Researchers can now access new information about how the COVID-19 pandemic impacted the lives of almost 28,000 cohort study participants during the third national lockdown in February and March.
This newly released data comes from Wave 3 of the COVID-19 Survey in Five National Longitudinal Studies. Together with the information gathered during the first two waves of survey data collection, researchers now have access to data about the experiences of more than 34,000 individuals during the coronavirus crisis.
This new Wave 3 information will help researchers understand how people's lives have changed since the earlier two surveys, which took place in May 2020 (Wave 1) and then during September and October (Wave 2). The data collected from participants, aged between 19 and 74 at the time of Wave 1, provides important insights into the economic, health and social consequences of the coronavirus outbreak.
The latest survey closely mirrored the topics covered in Waves 1 and 2. However, new questions were included to reflect the evolving crisis, on subjects such as the vaccination programme and long COVID. In addition, as in Wave 1, participants were asked to share, in their own words, how the pandemic had affected them and their loved ones, providing an opportunity for qualitative research.
Around 5,000 new participants completed the survey in Wave 3, in addition to the 23,000 participants who also took part in one or both of the previous two waves.
The survey was sent to participants in all four national longitudinal cohort studies run by the UCL Centre for Longitudinal Studies (CLS) as well as participants in the MRC National Survey of Health and Development, run by the MRC Unit for Lifelong Health and Ageing (LHA), also based at UCL. The five studies included are:
These studies have been following large, representative cohorts since birth, gathering information about different aspects of participants' lives, at different stages of their lives. Researchers will be able to analyse these new Wave 3 COVID-19 survey data in conjunction with data from Waves 1 and 2 of the survey, as well as the longitudinal data collected over the lifetime of each study.
Professor Alissa Goodman said: "Since first contacting our study participants in May 2020, more than 34,000 people from across four generations have shared their insights into how the coronavirus outbreak has affected their livelihoods, their families and relationships and their physical and mental health.
"With each new wave of the survey, we've seen the numbers of respondents increase, helping us to build a more representative, accurate picture of how the COVID-19 crisis has impacted the whole of society. Using the information we've gathered from these three waves with other study data, collected across more than 70 years, researchers will be able to examine how prior life experiences shape resilience or vulnerability to the effects of the pandemic both in the short term, and much further into the future."
Find out more about the data
For more information about the design and content of the survey, the response, data collected and weights, see the CLS website COVID-19 survey page. The questionnaire and user guide are both available to download.
A CLS webinar on Thursday 17 June will give researchers an overview of the three waves of the survey, focusing on content, how to deal with non-response and research findings. For more details and to register, see the CLS website.
Access the data
The online survey data from Waves 1, 2 and 3 from the four CLS studies taking part, namely the MCS, Next Steps, BCS70 and NCDS, have been de-identified and are available for researchers to download under End User Licence from the UK Data Service:
To download the data (SN: 8658), visit the UK Data Service website.
The data are also available from each of the main pages for the four studies on the UK Data Service website:
Weights have been provided with this COVID-19 dataset to take account of non-response to the survey, in order to help researchers produce representative results.
See the user guide to the data for more information.
Wave 1 and Wave 2 data from the MRC National Survey of Health and Development is available from the UK Data Service under Special Licence Access. Wave 3 data will be available from the UK Data Service shortly, and in the interim researchers can submit an application to the study to access the Wave 3 data.

Halloween, Valentine's Day Found to Influence Birth Timing
Halloween and Valentine's Day appear to influence when expecting mothers give birth, new research at the Yale School of Public Health has found. Halloween, with its symbolism of witches and death, is treated as an unfavorable day for childbirth. In contrast, Valentine's Day, with its symbolism of flowers and love, is treated as a favorable day for childbirth. The study found a decrease in births on Halloween and an increase on Valentine's Day. The association of the two holidays with birth patterns was shown for the first time. On Halloween there was a 5.3 percent decrease in spontaneous births and a 16.9 percent decrease in cesarean births, compared to other births occurring within one week before and one week after the October holiday. Whereas, on Valentine's Day there was a 3.6 percent increase in spontaneous births and a 12.1 percent increase in cesarean births.
"The study suggests that beliefs arising from our culture can have a greater impact on physical functioning than we might suspect," says Becca Levy, lead author and associate professor of epidemiology and psychology at Yale. Study co-authors were Martin Slade and Pil Chung, also at Yale. The findings show that pregnant women may have some control over the timing of spontaneous births—traditionally believed to be beyond their control—and that scheduled births are also affected by the symbolism of the two holidays. The study drew on birth-certificate information for all births in the United States across 11 years. The Halloween period included 1.8 million births, and the Valentine's Day period included 1.6 million births. The findings are published in the current issue of the journal Social Science and Medicine.

Social media such as Twitter generate large quantities of data about what a person is thinking and doing in a particular location. We leverage this data to build models of locations to improve our understanding of a user's geographic context. Understanding the user's geographic context can in turn enable a variety of services that allow us to present information, recommend businesses and services, and place advertisements that are relevant at a hyper-local level.
In this paper we create language models of locations using coordinates extracted from geotagged Twitter data. We model locations at varying levels of granularity, from the zip code to the country level. We measure the accuracy of these models by the degree to which we can predict the location of an individual tweet, and further by the accuracy with which we can predict the location of a user. We find that we can meet the performance of the industry standard tool for predicting both the tweet and the user at the country, state and city levels, and far exceed its performance at the hyper-local level, achieving a threeto ten-fold increase in accuracy at the zip code level.

Massive Animal Feces are the special excrements currently only produced by Titanosaur in ARK: Survival Evolved. From time to time, they automatically drop from these creatures. If you eat this you will probably die.
Usage[edit | edit source]
Massive Animal Feces can be used as fertilizer and add 35,000 points to fertilization when they are put in the inventory of a Crop Plot.
They can be combined with Thatch in a Compost Bin to produce Fertilizer.
However, it is the only Feces which is partially not worth doing it, it would be better to directly insert them into Crop Plots, as a Fertilizer has less fertilization points (54,000) than 2 or 3 Massive Animal Feces separated (70,000 or 105,000). Therefore, it would be more efficient to combine any other animal feces with thatch to produce fertilizers. The only way it could be somewhat efficient to combine it into fertilizer is if one would use a single Massive animal Feces with 2 other smaller variants. (Excluding two Large Animal Feces or one Large Animal Feces and one Medium Animal Feces, as the sum of their separated fertilization points would still be greater than the Fertilizer's)
Unlike the other size variations of feces, as of Patch 243.2, Massive Animal Feces cannot be used for taming Dung Beetles. However, they can be converted by the Dung Beetles, given a high enough weight stat, into 16 bags of Fertilizer and 14 Oil per feces.[1]

Supporting the Development of Lightweight Design Structures with Simple Methods in Early Stages
Editor: Miko Laakso, Kalevi Ekman
Author: Posner, Benedikt; Binz, Hansgeorg; Roth, Daniel
Institution: University of Stuttgart, Germany
Section: Tools, methods and approaches in product development
Mattheck presents very simple methods for developing lightweight design structures based on bionic ideas. These methods can already be used to develop structures on a very low level of detail. This allows developing structures with a view on lightweight design already in the conceptual phase. In order to do this there is no need for computer aided methods. However, the methods of Mattheck focus on static problems and do not support finding solutions for problems with a limited installation space. Thus, within this contribution the methods were combined with the Contact and Channel Model which is a method for supporting designers in analysing products, their structures and functions and synthesising solutions for design problems. In addition, the methods of Mattheck are further developed in order to support developing lightweight structures respecting also the problem of moved structures with different loadings over time and respecting the installation space limitation.

Henry Fairfield Osborn was an American naturalist, notable for his involvement in and contribution to many environmental organizations.
Osborn was born in Princeton, New Jersey, in 1887. He attended both Princeton and Cambridge Universities, after which he worked in a variety of jobs, including as a soldier in World War I.
Having followed his paleontologist father on archeological digs, however, Osborn became interested in science as a career. He soon became secretary of the New York Zoological Society and went on to serve for many years as its president. He also worked
to support the creation of the Marine Aquarium at Coney Island, New Jersey, and the upkeep of the Bronx Zoological Park. Concerned for endangered species, in 1947 Osborn also founded the Conservation Foundation, an adjunct to the New York Zoological Society and later part of the World Wildlife Fund.
Osborn took his environmentalism to Washington, D.C. He served on the
Conservation Advisory Committee of the U.S. Department of the Interior and on the Planning Committee of the Economic and Social Council of the United Nations.
Osborn was also concerned about the effect of population growth on the supply of natural resources, and he worked for solutions to this problem. He wrote two books, Our Plundered Planet (1948), and The Limits of the Earth (1953). He was a member of many other environmental organizations
including the Save-the-Redwoods League and the International Council for Bird Preservation. Henry Osborn died in 1968.

San Francisco (CA) – The Federal Communications Commission (FCC) has confirmed plans to hold a public meeting aimed at scrutinizing the wireless industry. An FCC spokesperson told TG Daily that the probe will include three separate presentations, including one session dedicated to the 'empowerment' of American consumers.
"The Commission will consider a Notice of Inquiry that seeks comment on whether there are opportunities to protect and empower American consumers by ensuring sufficient access to relevant information about communications services," the FCC explained in an official statement.
The agency is also expected to review various factors meant to encourage wireless innovation and "identify concrete steps" to encourage further investment. Finally, the FCC is slated to examine information for the next annual report to Congress on the status of competition in the mobile wireless market.
As TG Daily previously reported, the federal government has made a salient effort to step up its scrutiny of the wireless industy.
For example, the FCC recently initiated an informal investigation into Apple's rejection of Google's iPhone voice application.
In addition, the Department of Justice (DoJ) launched a wide-ranging review of major telecommunications companies over possible anti-trust violations, while four senators informed the FCC of their intention to investigate wireless exclusivity agreements.

WP-MIRROR is a free utility for building mirrors of any desired set of Wikimedia Foundation wikis.
Which Wikis[edit | edit source]
WP-MIRROR can build mirrors of any desired set of these wikis.
Why Build a Mirror[edit | edit source]
The main use cases for a mirror are these:
- Development. If you are technically minded and need a mirror with which you may conduct experiments;
- Infrastructure. If you need redundancy, or need to serve pages locally to minimize telecommunications traffic;
- Offline browsing. If you need off-line access, perhaps for reasons of mobility, availability, and privacy; and
- Research. If you need a mirror as a tool to assist your research on the contents of any given wiki.
Key Features[edit | edit source]
WP-MIRROR builds a set of mirrors with the properties:
- Appearance. A wiki page rendered by a mirror looks very similar to the same page rendered by the WMF servers;
- Behavior. A wiki page rendered by a mirror behaves almost the same (e.g. edit, search, user account creation, beta features); and
- Completeness. Builds a complete mirror with original size images.
WP-MIRROR is easy:
- Easy to install. Available as a DEB package, and is available from a Debian package repository;
- Easy to configure. The user may select any desired set of wikis by editing just one line in a configuration file;
- Easy to use. Sets up virtual hosts such as _URL_ _URL_ and _URL_ one for each wiki in the set, which the user may access with a web browser; and
- Robust. Stable even in the face of: corrupt dump files, corrupt media files, incomplete downloads, Internet access interruptions, and low disk space; and uses check-pointing to resume after process interruption.
WP-MIRROR automatically configures other software:
- Apache2. Enables the URL rewrite module, and enables virtual hosts;
- Cron. Sets up a cron job that updates the mirrors weekly;
- MediaWiki. Configures MediaWiki 1.24 and several dozen extensions; and
- MySQL. Configures MySQL to achieve an order-of-magnitude improvement in database performance.
WP-MIRROR is free:
- Free software. Software is released under the GNU General Public License (GPLv3); and
- Free documentation. Documentation is released under the GNU Free Documentation License, version 1.3.
Out-of-the-box Experience[edit | edit source]
WP-MIRROR by default, builds the following set of mirrors:
where Simple English means shorter sentences, and Wikidata is a centralized collection of facts usable by all other wikis (e.g. to populate infoboxes).
The default works out-of-the-box with no user configuration. It should build in 200ks (two days), occupy 150G of disk space, be served locally by virtual hosts: _URL_ _URL_ and _URL_ and update automatically every week.
The default should be suitable for anyone who learned English as a second language (ESL).
Largest Wikis[edit | edit source]
The largest wikis (with over a million articles each) are: en, sv, de, nl, fr, war, ru, it, ceb, es, vi, and pl. Because WP-MIRROR uses original size media files, the largest wikis are too large to fit on a laptop with a single 500G disk, unless the user does not need the images (and this is configurable). The en wikipedia is the most demanding case. It should build in 1Ms (twelve days), occupy 3T of disk space, be served locally by virtual host _URL_ and update automatically every month.
Platforms[edit | edit source]
WP-MIRROR 0.7.4 is known to install out-of-the-box on the following platforms:
- Debian 7.4 (wheezy) with backports. Tested both on a host, and on a virtual machine.
- Ubuntu 14.04 (trusty). Tested on a virtual machine.

Take the 2-minute tour ×
There is a well known correspondence between line bundles over curves and divisors. For each line bundle, consider a rational section, take poles and zeros and we have a corresponding divisor (up to linear equivalence ). But what if there is no such section? For example, consider a line bundle over $\mathbb{P}^1$ with transition function $e^{1/z}$ with $z \neq 0,\infty$. What is the degree of this line bundle?
share|improve this question
The transition function is holomorphic at $\infty$ so the line bundle is trivial. – Torsten Ekedahl Jul 20 '11 at 6:33
Dear Torsten, your argument is a little incomplete. After all, the non-trivial bundle $\mathcal O(k)$ for $k>0$ has as transition function $1/z^k$, which is holomorphic at $\infty$. The crucial point is that indeed $e^{1/z}$ is holomorphic but also that it has neither zeros nor poles on $\mathbb P^1\setminus 0$. – Georges Elencwajg Jul 20 '11 at 8:59
Dear Georges, yes I forgot to say that it and its inverse are holomorphic at $\infty$. – Torsten Ekedahl Jul 20 '11 at 14:15
2 Answers 2
Here is the way you get a non-vanishing holomorphic section which will trivialize your line bundle.
Denote $U_1=\{[x:y]; x\neq 0 \}$ and $U_2=\{[x:y]; y\neq 0\}$, this is a covering of $\mathbb P^1$. The transition function of the bundle is $g_{12}([x:y])=e^{y/x}$ (you could also take $e^{x/y}$, this wouldn't change the argument), defined on $U_1 \cap U_2$.
Then you may defined the following holomorphic functions: on $U_1$, you put $s_1([x:y]):=e^{y/x}$ and on $U_2$, $s_2([x:y]):=1$. Thus $s_1$ and $s_2$ are non-vanishing holomorphic functions, and on $U_1 \cap U_2$, you have $s_1=g_{12}s_2$ so that they form a section of our line bundle.
EDIT: In particular the degree of the line bundle is 0!
Moreover, on a Riemann surface (or more generally on any smooth projective complex variety), any line bundle admits a meromorphic section, so that the correspondence your are talking about still holds.
share|improve this answer
As several people have pointed out, your example has degree $0$. Another way to see this is to observe that given a section, the number of zeros minus poles in both hemispheres is a difference of two winding numbers. This would work out to $(1/2\pi i)\int_\gamma d\log g_{12}$, where $\gamma$ is the equator and $g_{12}$ is the transition function (as in Henri's answer). In fancier terms, this is the first Chern number. In your example, this works out to $0$ (again). For $\mathbb{P}^1$, the degree is the sole invariant.

Аннотация: A simple test procedure was developed for testing pitch infiltration (pitch wetting) in to the coke, which is based on using pitch preformed specifically made for the tests. The test procedure avoids some of the issues with existing pitch wetting procedures related to the time consumed in the test, degree of variation of test resulПоказать полностьюts and sensitivity to even minor changes in the experimental lay-out. The test procedure looks for the coefficient of pitch infiltration which is not dependent on such factors as the mass of pitch or coke, the shape or size of the pitch or coke and it eliminates the influence of the test container material with the coke and pitch placed for experiments. The procedure is highly sensitive to changes in the pitch properties and the resultant rate of pitch infiltration into the coke is independent of the coke and pitch properties.

Numerous forms of policies, licensing terms, and related conditions are associated with Web data and services. A natural goal for facilitating the re-use and re-combination of such content is to model usage policies as part of the data so as to enable their exchange and automated processing. This paper thus proposes a concrete policy modelling language. A particular difficulty are self-referential policies such as Creative Commons ShareAlike, that mandate that derived content is published under some license with the same permissions and requirements. We present a general semantic framework for evaluating such recursive statements, show that it has desirable formal properties, and explain how it can be evaluated using existing tools. We then show that our approach is compatible with both OWL DL and Datalog, and illustrate how one can concretely model self-referential policies in these languages to obtain the desired conclusions.

At the end of last month, September 27th-29th, the Climate Advanced Forecasting of sub-seasonal Extremes Final Conference (CAFE) was celebrated. CAFE is a Marie Skłodowska-Curie Innovative Training Network with a consortium formed by ten international partners recruiting, hosting and interdisciplinary training a total of 12 Early Stage Researchers (ESRs). The research aim of the project is to improve the predictability of extreme weather events at the sub-seasonal scale from fields such as climate science, complex networks and data analysis.
The conference was meant to bring together the project's principal researchers and the pre-docs trained through it. It also gathered other senior scientists related to the partners of the project or working in similar topics. For a total of 7 plenary talks, 9 contributed talks and 8 ESRs presentations, they shared their latest developments. During the poster sessions and more informally in eating breaks and social events, they could discuss their different approaches to the study of extreme events. The different backgrounds of the participants were also valuable during the three round tables, two under the framework of the European Researchers Night (ERN).
The conference took place in Casa de la Convalescència in Barcelona, since one of the partners of the project is Centre de Recerca Matemàtica, a Catalan research center located in Bellaterra, near Barcelona.
On Tuesday morning, Álvaro Corral (the CAFE coordinator, researcher at CRM) and Arantxa Sanz (CRM's Executive Director) were in charge of welcoming attendants of the conference. After that, Frederic Vitart from ECMWF, the first keynote speaker, set the scene of the project. He introduced the sub-seasonal study of extreme events and their challenges, as well as the main sources of predictability. After that, Shradda Gupta was the first ESR to present her research. During the day, 3 more of them presented the academic work of these past years, mostly focusing on the applications on prediction models and warning systems. All in all, Monday was a day with a focus on the users of climate services, with Carlo's Buontempo (ECMWF) and Albert Soret's (BSC) plenary talks and a round table moderated by Cèline Deàndreis (Aria Technologies) of Forecasting made with and for the Users.

Wednesday's sessions started with Ileana Bladé's plenary talk on evidence and hypothesis for the increase of extreme weather events in midlatitudes. The morning went on with talks related to climate change and the prospects of its impact on the climate from different perspectives: from the anthropogenic role on it, to the tools used for the simulations. After lunch the participants enjoyed a tour in the beautiful Hospital de Sant Pau modernist building.

On Wednesday afternoon, some scientists from the Final Conference participated in the Catalan version of the European Research Night in the same venue as the closing event. There were two round tables and 4 talks that shared the intention of making the research on the project more understandable to non-scientists and had the aim of motivating potential young climate scientists as well as giving them tips to get started in a scientific career. As a highlight, the last round table reunited 4 senior researchers from the project that gave their point of views on the new methods in meteorology and climatology, as well as, for example, climate change communication and science communication in general.
Round Table: ¿Qué hace un doctorando como tú en una red europea como esta?¿Y después? (in Spanish) with Pedro Herrera Lorméndez (TU Bergakademie Freiberg), Niclas Rieger (CRM), Mónica Minjares (CRM), Iago Pérez (Universidad de la República) and Giulio Tirabassi (UPC). Moderated by Anna Drou (CRM).

Round Table: Nuevos métodos en meteorología y climatología (in Spanish) with Marcelo Barreiro (Universidad de la República), Ileana Bladé (UB), Emilio Hernández-García (IFISC-CSIC) and Cristina Masoller (UPC). Moderated by Daniel Ramos (CRM).
Wednesday was a last powerful day with several plenary and contributed talks that addressed issues such as drivers behind weather extreme events, how climate change has potentially been affecting some of them, how these drivers affect large-scale circulations, and more on complex systems models and statistical methods to predict weather extremes.
During the three days of the conference, a wide variety of topics related to extreme weather events and the methods to improve their prediction in a sub-seasonal timescale were discussed in different formats. It was an encounter that grouped most of the participants in the CAFE project as well as opened to the research community with shared interests. The Conference was an important milestone of the CAFE project, that was helpful to put in common the work of the pre-docs and partners from the last three years.
At this stage of the project, it is close to its finalization. However, there are some things left to do to report the scientific outcomes. Next steps to collect and organize all the results of the project are to develop an exploitation roadmap of the outputs of the project to make sure that they reach different users, from businesses to government agencies. Another deliverable will be a summary of the findings to be used by policy makers.


text: Highly functionalized picolinic acids are plant growth regulators used as broadleaf herbicides to control weeds that crop up in grain fields and pastures. In an effort to develop more potent versions of the herbicides and with an eye toward lowering their environmental impact, a research team at Dow AgroSciences has developed a new synthetic approach to making picolinic acids (Org. Lett. 2015, DOI: 10.1021/acs.orglett.5b01176). Peter L. Johnson, Gregory T. Whiteker, Natalie C. Giampietro, and coworkers first scoped out how to make 4-amino-3-chloro-5-fluoropicolinates (shown) that have alkyl or aryl groups (R) at the 6-position of the pyridine ring. Chemists previously had tried fluorinating aminopicolinic acids followed by a standard cross-coupling step to add the alkyl or aryl group but with limited success. The Dow researchers decided to try a cascade cyclization reaction strategy instead. They generated N-protected fluoroalkyl alkynylimine intermediates, treated the intermediates with a primary amine, and after deprotection and chlorination steps reached their target. The cascade cyclization reaction has been patented by Dow, and the team has already used it to synthesize Rinskor Active, a low-application-rate herbicide that is pending regulatory approval for use on rice and other crops.

Part of the confusion about this is the order:

Insurance license renewal and initiation is an important process for insurers to consider. Each state has different processes and necessities that must be fulfilled in order for the renewal process to become satisfied. Understanding these requirements and complying with them is crucial. Here are a few things to keep in mind regarding insurance licensing:
1. Understand the Requirements for Each State
When initiating a license in a particular state, there may be different requirements for each state. For example, Georgia requires a citizenship affidavit and Florida requires finger prints. It is important to understand these issues and take note of them to order licenses correctly.
2. Follow Changes In Laws and Regulations
These are constantly changing in every state. If you are not properly informed of these changes you may fall out of compliance. For example, Massachusetts recently changed continuing education requirements to include three credits of ethics as well as changing the CE deadline to the producer's license renewal date (see here).
3. Take Note of Renewal Dates
It is crucial to take note of when these dates are upcoming so your licenses do not become out of compliance. When you forget to renew a given license, fees and penalties can follow along with them. Selling policies while improperly licensed not only can result in penalties, but also result in suspension as well as adversely affecting your reputation.
The insurance license process can be hard for businesses to manage with so many other priorities needing attention. The National License Compliance Group (NLC Group) can take care of these critical tasks for you and ensure you will never become out of compliance. With our specialized services offering email alert notifications and management dashboards to display license and appointment information, the license management process can be a breeze.

David Griffiths, Timothy Goddard and Mi Wang: Why has IMS LD not led to the advances which were hoped for?
Cloud created by:
5 October 2011
The publication of the IMS Learning Design (LD) specification in 2003 led to high hopes that the specification would lead to advances both in formalising the description of learning designs and patterns, and also of extending the range of possible learning designs which could be implemented with technological support. Today, however, there is no evidence that it has achieved anything approaching widespread adoption within the education sector. This study seeks to identify the reasons for this, and the lessons which can be learned for future research into learning designs and patterns. We describe how data is currently being gathered in the form of interviews with leading participants in IMS LD research, and how this will be analysed in order to identify hypotheses which can clarify the history of the specification in the form of proposed explanatory mechanisms. The results of this process will be presented at the ASLD workshop. Subsequently an open process will be carried out to contrast these hypotheses with evidence in the existing literature, and to develop conclusions regarding the lessons for future research into learning design and pedagogic patterns.


a Python frame is active. This feature is not enabled by default, so you turn it on by right-clicking in the Locals window and toggling the Python > Show C++ View Nodes menu option.
Enabling C++ View
The "[C++ View]" node provides a representation of the underlying C/C++ structure for a value, identical to what you'd see in a native frame. For example, it shows an instance of _longobject (for which PyLongObject is a typedef) for a Python long integer, and it tries to infer types for native classes that you have authored yourself. The children of this node are editable.
C++ View
If a child field of an object is of type PyObject, or one of the other supported types, then it has a "[Python View]" representation node (if those representations are enabled), making it possible to navigate object graphs where links are not directly exposed to Python.
Unlike "[Python View]" nodes, which use Python object metadata to determine the type of the object, there's no similarly reliable mechanism for "[C++ View]". Generally speaking, given a Python value (that is, a PyObject reference) it's not possible to reliably determine which C/C++ structure is backing it. The mixed-mode debugger tries to guess that type by looking at various fields of the object's type (such as the PyTypeObject referenced by its ob_type field) that have function pointer types. If one of those function pointers references a function that can be resolved, and that function has a self parameter with type more specific than PyObject*, then that type is assumed to be the backing type. For example, if ob_type->tp_init of a given object points at the following function:
static int FobObject_init(FobObject* self, PyObject* args, PyObject* kwds) {
 return 0;
}
then the debugger can correctly deduce that the C type of the object is FobObject. If it's unable to determine a more precise type from tp_init, it moves on to other fields. If it's unable to deduce the type from any of those fields, the "[C++ View]" node presents the object as a PyObject instance.
To always get a useful representation for custom authored types, it's best to register at least one special function when registering the type, and use a strongly-typed self parameter. Most types fulfill that requirement naturally; if that's not the case, then tp_init is usually the most convenient entry to use for this purpose. A dummy implementation of tp_init for a type that is present solely to enable debugger type inference can just return zero immediately, as in the code sample above.
Differences from standard Python debugging
The mixed-mode debugger is distinct from the standard Python debugger in that it introduces some additional features but lacks some Python-related capabilities:
 - Unsupported features: conditional breakpoints, Debug Interactive window, and cross-platform remote debugging.
 - Immediate window: is available but with a limited subset of its functionality, including all the limitations listed here.
 - Supported Python versions: CPython 2.7 and 3.3+ only.
 - Visual Studio Shell: When using Python with Visual Studio Shell (for example, if you installed it using the integrated installer), Visual Studio is unable to open C++ projects, and the editing experience for C++ files is that of a basic text editor only. However, C/C++ debugging and mixed-mode debugging are fully supported in Shell with source code, stepping into native code, and C++ expression evaluation in debugger windows.
 - Viewing and expanding objects: When viewing Python objects in the Locals and Watch debugger tool windows, the mixed-mode debugger shows only the structure of the objects. It does not automatically evaluate properties, or show computed attributes. For collections, it shows only elements for built-in collection types (tuple, list, dict, set). Custom collection types are not visualized as collections, unless they are inherited from some built-in collection type.
 - Expression evaluation: see below.
Expression evaluation
The standard Python debugger allows evaluation of arbitrary Python expressions in Watch and Immediate windows when the debugged process is paused at any point in the code, so long as it is not blocked in an I/O operation or other similar system call. In mixed-mode debugging, arbitrary expressions can be evaluated only when stopped in Python code, after a breakpoint, or when stepping into the code. Expressions can be evaluated only on the thread on which the breakpoint or the stepping operation occurred.
When stopped in native code, or in Python code where the conditions above do not apply (for example, after a step-out operation, or on a different thread), expression evaluation is limited to accessing local and global variables in scope of the currently selected frame, accessing their fields, and indexing built-in collection types with literals. For example, the following expression can be evaluated in any context (provided that all identifiers refer to existing variables and fields of appropriate types):
foo.bar[0].baz['key']
The mixed-mode debugger also resolves such expressions differently. All member-access operations look up only fields that are directly part of the object (such as an entry in its __dict__ or __slots__, or a field of a native struct that is exposed to Python via tp_members), and ignore any __getattr__, __getattribute__ or descriptor logic. Similarly, all indexing operations ignore __getitem__, and access the inner data structures of collections directly.
For the sake of consistency, this name resolution scheme is used for all expressions that match the constraints for limited expression evaluation, regardless of whether arbitrary expressions are allowed at the current stop point. To force proper Python semantics when a full-featured evaluator is available, enclose the expression in parentheses:
(foo.bar[0].baz['key'])


Plotting equations using EZPLOT – Matlab
Plotting is a very important step in the study of a system, since it helps understand the behavior and the restrictions of system with the less effort possible.
Plotting an equation is not always an easy task especially if you have to work out all the parameters manually, luckily nowadays there are tons of tools that help plot equations.
Matlab is the most popular tools out there when it comes to the study of system, and in this post we are going to work with some basic equations, Matlab, and most importantly make use of EZPLOT for plotting equations.
Plotting equations in Matlab using EZPLOT
 Ezplot Matlab example
plot-equation-in-matlab
To plot this equation in Matlab using the EZPLOT, We will write the equation the following way
plot-equation-in-matlab
Now type the following code and press ENTER
ezplot('y-x^3-x^2+x-1',[-5 5 -5 5])
And you will obtain the following figure
plotting-in-matlab
If you would like to have more information about the command we just used, you can find it by using the following code
doc ezplot
While using the EZPLOT, the structure of the code is the following
ezplot(fun,[xmin,xmax,ymin,ymax])
Where fun is the equation, xmin and xmax are respectively the lower and the highest value of x, ymin and ymax the lowest and highest value of y. If the most interesting part of the graph your are plotting is happening in a larger interval than the one we just plotted, you may need to increase the value of xmin, xmax, ymin and ymax.

In the world of home construction, balloon framing stands tall as a pioneering technique. Like a thread weaving through time, it has left a profound mark on the industry.
This method boasts cost-effectiveness, creating spacious interiors and facilitating rapid construction. However, its fiery nature and insulation challenges raise concerns. Nevertheless, its structural integrity remains a point of admiration.
This article dives into the pros and cons of balloon framing, shedding light on its historical significance and practical considerations.
- Balloon framing emerged in the mid-19th century, simplifying the construction process and reducing costs.
- Balloon framing offers a spacious interior with an open floor plan and versatile room layout.
- Rapid construction is possible with balloon framing, allowing for quicker project completion.
- However, balloon framing presents fire hazards and insulation challenges that need to be addressed for safety and energy efficiency.
The construction technique of balloon framing has significantly influenced the history of architecture. Balloon framing, which emerged in the mid-19th century, revolutionized the way buildings were constructed. Prior to its introduction, most buildings were constructed using traditional timber framing, which was time-consuming and required skilled craftsmen.
Balloon framing, on the other hand, simplified the construction process and allowed for faster and cheaper building projects. One of the main advantages of balloon framing was its use of long, continuous studs that extended from the foundation to the roof. This eliminated the need for load-bearing walls on each floor, resulting in more open and flexible interior spaces. Moreover, balloon framing allowed for the construction of taller buildings, as the continuous studs provided increased structural support.
The widespread adoption of balloon framing had a profound impact on the growth of cities and towns. It enabled the rapid construction of residential and commercial buildings, meeting the increasing demand for urban infrastructure during the Industrial Revolution. This construction technique also played a significant role in the westward expansion of the United States, as it allowed for quick and efficient building in new settlements.
Balloon framing offers a cost-effective solution for construction projects. This method of construction, which originated in the 19th century, involves long, continuous studs that extend from the foundation to the roof. It eliminates the need for intermediate load-bearing walls, reducing the overall material and labor costs.
One of the main advantages of balloon framing is its efficiency in utilizing lumber. By using longer studs, fewer pieces of lumber are needed, resulting in cost savings. Additionally, the simplicity of the construction process allows for faster and more efficient assembly, reducing labor costs.
To further highlight the cost-effectiveness of balloon framing, let's compare it to the traditional platform framing method in a table:
|Aspect||Balloon Framing||Platform Framing|
As shown in the table, balloon framing offers advantages in terms of lumber usage, construction time, labor cost, and material cost compared to platform framing.
Balloon framing offers a spacious interior due to its open floor plan, allowing for a seamless flow between rooms. This design also provides versatility in room layout, giving homeowners the freedom to customize and rearrange spaces according to their needs.
With maximum living space, balloon framing proves to be an excellent choice for those who value a spacious and adaptable home.
Open Floor Plan
A popular feature of balloon framing is its ability to create an expansive and inviting open floor plan. With balloon framing, the use of long vertical studs allows for larger spans between walls, eliminating the need for load-bearing walls in the interior. This design concept opens up the space, creating a seamless flow from room to room.
The absence of walls not only creates a sense of spaciousness but also allows for more natural light to penetrate the entire area, making it feel bright and airy. Additionally, an open floor plan promotes better communication and interaction among family members or guests.
It provides a flexible layout that can be easily customized to suit the needs and preferences of the homeowners. Whether it's for entertaining, family gatherings, or simply enjoying a comfortable and open living space, an open floor plan is a desirable feature that balloon framing offers.
Versatile Room Layout
The versatile room layout of balloon framing allows for a spacious interior, providing homeowners with endless possibilities for arranging and organizing their living space.
Balloon framing, with its minimal use of interior load-bearing walls, creates wide open spaces that can be easily reconfigured to meet the changing needs of a household. This flexibility allows homeowners to create a layout that suits their lifestyle and preferences.
Whether they want an open concept design for entertaining guests or separate rooms for privacy and functionality, balloon framing can accommodate it all. Additionally, the absence of load-bearing walls allows for creative and unique room shapes and sizes, giving homeowners the freedom to think outside the box and design a space that truly reflects their individuality.
With a versatile room layout, homeowners can maximize the use of their interior space and create a home that suits their needs perfectly.
Maximum Living Space
To maximize their living space, homeowners can enjoy a spacious interior by utilizing balloon framing in their home construction. Balloon framing offers several advantages that contribute to creating a generous amount of living space:
- Taller ceilings: Balloon framing allows for higher ceilings, creating a sense of openness and spaciousness.
- Uninterrupted floor plans: With fewer interior walls needed for support, homeowners can enjoy uninterrupted floor plans, allowing for flexible and customizable room layouts.
- Ample natural light: The taller walls in balloon framing allow for larger windows, flooding the interior with natural light and making the space feel even more expansive.
- Potential for additional levels: Balloon framing provides the structural integrity needed to add additional levels, further increasing the living space available.
- Greater design possibilities: The open and flexible nature of balloon framing allows for creative design choices, such as open concept living areas and unique architectural features.
Typically, balloon framing allows for more rapid construction compared to traditional methods. This is mainly due to the fact that balloon framing utilizes long, continuous studs that run from the foundation all the way up to the roof. This eliminates the need for time-consuming and labor-intensive framing of individual floor levels, resulting in a faster construction process.
With balloon framing, once the foundation is laid and the initial studs are in place, the construction crew can quickly install the exterior walls by attaching them to the continuous studs. This method allows for the simultaneous construction of multiple floors, as the studs extend vertically through the entire height of the building. As a result, the construction process is significantly expedited, allowing for the completion of the framing stage in a shorter timeframe.
Moreover, the rapid construction offered by balloon framing can save both time and money. The quicker construction time means that the building can be completed sooner, enabling owners to move in or start generating revenue sooner. Additionally, the reduced labor required for framing can lead to cost savings, especially when considering the shorter construction schedule.
Unfortunately, fires can occasionally occur due to the unique construction method of balloon framing. While this method offers several advantages, it also presents certain fire hazards that need to be considered. Here are some of the key concerns:
- Vertical Fire Spread: One of the main dangers of balloon framing is the potential for rapid vertical fire spread. The open wall cavities act as chimneys, allowing flames and smoke to quickly travel from one floor to another.
- Lack of Firestopping: Balloon framed walls often lack firestopping materials, which are essential for containing fires and preventing their spread. Without proper firestopping, flames can easily move throughout the structure, endangering occupants and causing extensive damage.
- Difficult Access for Firefighters: The vertical design of balloon framed buildings can make it challenging for firefighters to access the upper levels during a fire. This can delay their response and potentially hinder rescue efforts.
- Hidden Fires: Another concern is the possibility of hidden fires within the wall cavities. This can make it difficult to detect and extinguish fires, allowing them to grow undetected until they break out and cause significant damage.
- Obsolete Fire Safety Standards: Balloon framing was popularized in the 1800s when fire safety standards were less stringent. As a result, older balloon framed buildings may not meet modern fire safety codes, further increasing the risk of fire incidents.
While balloon framing offers many benefits in terms of construction speed and flexibility, it's crucial to address these fire hazards and implement appropriate fire safety measures to protect both the occupants and the structure itself.
Due to the unique construction of balloon framing, homeowners and contractors may face insulation challenges, but they can be overcome with careful planning and implementation.
Balloon framing, characterized by long vertical studs that extend from the foundation to the roof, creates uninterrupted vertical cavities throughout the walls. This design makes it difficult to properly insulate the walls and prevent heat loss or gain.
One of the main challenges with insulating balloon framed walls is the potential for air leakage. The long vertical cavities can create pathways for air to flow freely, reducing the effectiveness of insulation. To address this issue, homeowners and contractors need to ensure that all gaps and cracks in the walls are sealed properly. This can be achieved by using caulking or foam insulation to seal any openings.
Another challenge is ensuring consistent insulation coverage in the walls. The vertical cavities can make it difficult to evenly distribute insulation material. To overcome this, it's important to use proper installation techniques, such as dense packing or blowing insulation into the cavities. Additionally, installing a vapor barrier can help prevent moisture from entering the wall cavities and causing damage to the insulation.
One of the main advantages of balloon framing is that it allows for longer spans and fewer load-bearing walls, resulting in a more open and flexible floor plan. This type of framing relies on the structural integrity of

ABSTRACT

Trace-driven simulations of numerical Fortran programs are used to study the impact ofthe parallel loop scheduling strategy on data prefetching in a shared memorymultiprocessor with private data caches. The simulations indicate that to maximizememory performance, it is important to schedule blocks of consecutive iterations toexecute on each processor, and then to adaptively prefetch single-word cache blocks tomatch the number of iterations scheduled. Prefetching multiple single-word cache blockson a miss reduces the miss ratio by approximately 5% to 30% compared to a system withno prefetching. In addition, the proposed adaptive prefetching scheme further reducesthe miss ratio while significantly reducing the false sharing among cache blocks compared to nonadaptive prefetching strategies. Reducing the false sharing causes fewer coherence invalidations to be generated, and thereby reduces the total network traffic. The impact of the prefetching and scheduling strategies on the temporal distribution ofcoherence invalidations also is examined. It is found that invalidations tend to be evenlydistributed throughout the execution of parallel loops, but tend to be clustered whenexecuting sequential program sections. The distribution of invalidations in both types of program sections is relatively insensitive to the prefetching and scheduling strategy.

text:
qc is a testing tool that lets you write properties that you expect to hold true, and let the computer generate randomized test cases to check that these properties actually hold. For example, if you have written compress and decompress functions for some data compression program, an obvious property to test is that compressing and decompressing a string gives back the original string. Here's how you could express that:
"""Test that compressing and decompressing returns the original data."""
data = qc.str() # An arbitrary string. Values are randomized.
self.assertEqual(data, decompress(compress(data)), repr(data))
That's an ordinary test with Python's built-in unittest framework (which is why there's so much boilerplate). Alternately, you could do the exact same thing with a different testing framework, like the minimally verbose, quite pleasant nose. The _USER_.property decorator runs the decorated function several times, and each time the values returned by functions like qc.string() are different. In other words, QuickCheck is compatible with pretty much every unit test framework out there; it's not particularly demanding.
Functions like qc.str(), qc.int(), and so on, generate arbitrary values of a certain type. In the example above, we're asserting that the property holds true for all strings. When you run the tests, QuickCheck will generate randomized strings for testing.
You'll notice that I said "randomized", not "random". This is intentional. The distribution of values is tweaked to include interesting values, like empty strings, or strings with NUL characters in the middle, or strings containing English text. In general, QuickCheck tries to give a good mix of clever tricky values and randomness. This is essentially what you would do, if you had to write really thorough test cases by hand, except that you don't have to do it. In practice, the computer has fewer preconceptions about what constitutes sane data, so it will often find bugs that would never have occurred to you to write test cases for. It doesn't know how to subconsciously avoid the bugs.
You're not limited to the built-in arbitrary value functions. You can use them as building blocks to generate your own. For example:
def __init__(self, x, y):
self.x, self.y = float(x), float(y)
"""Get an arbitrary point."""
x = qc.int(-20, 20)
y = qc.int(-34, 50)
return Point(x, y)
You can then use this to generate arbitrary point values in properties. Here's a nose-style test:
pt = point()
assert abs(pt.x) + abs(pt.y) >= math.sqrt(pt.x**2 + pt.y**2), (pt.x, pt.y)
When you run this, something magical happens: QuickCheck will try to generate tricky values for both the x and y variables in the Point class, together, so you'll see points like (0, 0), (1, 1), (0, 1), (385904, 0), as well as totally random ones like (584, -35809648). In other words, rather than just drawing x and y values from a stream of random numbers with some tricky values in it, QuickCheck will actually try to generate tricky combinations of x and y coordinates.
Functions for getting arbitrary data
- int(low, high) gives ints, between the optional bounds low and high.
- long(low, high) gives longs, between the optional bounds low and high.
- float(low, high) gives floats, between the optional bounds low and high. No Infinities or NaN values.
str(length=None, maxlen=None) gives strings, of type str. The encoding is UTF-8. If length is given, the strings will be exactly that long. If maxlen is given, the string length will be at most maxlen characters.
- unicode(length=None, maxlen=None) gives unicode strings, of type unicode. If length is given, the strings will be exactly that long. If maxlen is given, the string length will be at most maxlen characters.
- name() gives names, in Unicode. These range from the prosaic, like "John Smith", to the exotic -- names containing non-breaking spaces, or email addresses, or Unicode characters outside the Basic Multilingual Plane. This is, if anything, less perverse than the names you will see in a sufficiently large set of Internet data.
- nameUtf8() is the same as name().encode('utf8').
- fromList(items) returns random items from a list. This is mostly useful for creating your own arbitrary data generator functions.
- randstr(length=None, maxlen=sys.maxint) gives strings of random bytes. If length is given, the strings will be exactly that long. If maxlen is given, the string length will be at most maxlen bytes.
The strings produced by str and unicode are randomized, but some effort has been put into making them sufficiently perverse as to reveal bugs in a whole lot of string processing code. The name list is loosely based on horrible memories of seeing name processing code crash on real-world data, over and over and over again, as it became ever more clear that the world is mad, and we are truly doomed. (This feeling passes once you get enough test coverage and things finally stop crashing. There is hope!)
The name and string example data in qc.arbitrary may be interesting as a source of more deteministic test case data. Feel free to borrow any of it. The internals are magic, but of the magical internal parts, the most interesting ones are in qc.arbitrary and qc.

ClickHouse is an open-source, OLAP (Online Analytical Processing) database originally developed by the company Yandex, for the needs of its Metrica solution (similar to Google Analytics). Yandex is the first search engine used in Russia.

ClickHouse was developed with a simple objective: to filter and aggregate as much data as possible and as quickly as possible. Similar to other solutions of the same type (eg. Druid, Pinot), ClickHouse uses a column-oriented model for data storage. It also relies on various parallelization and vectorization mechanisms to take the most advantage of multi-core architectures. Hence, Clickhouse can support data volumes of several petabytes.

Let's start with Kyligence Cloud
First, I used Kyligence Cloud, if you also like to try Kyligence cloud, you may visit Kyligence to get a free trial. In order to analyze data, it is necessary to import data. I used a 100 million rows dataset which can fully exhibit strong query performance of ClickHouse.

The SSB (Star Schema Benchmark) dataset is designed to measure the performance of database products in support of classical data warehousing applications and is based on the TPC-H benchmark.There are 5 tables in the SSB dataset - table sampling is turned on by default. With sampling I can get statistical information of the entire dataset.

Auto-Modeling
In Kyligence Cloud, I enabled AI Augmented Mode to build models with SQL.

Created a model automatically from SQL command.

MDX
After building the model, let's explore MDX in Kyligence Cloud.

I need to set a name for MDX dataset. Here, the dataset was Kyligence Cloud model.

You could even define more complicated relationships among MDX datasets.

kyligence mdx3

When defining Semantics, you can define more objects, like Dimension, Measure, Hierarchy, Calculated Measure, etc.

In the C++ standard libraries I found only a floating point log method. Now I use log to find the level of an index in a binary tree ( floor(2log(index)) ).
Code (C++):
int targetlevel = int(log(index)/log(2));
I am afraid that for some of the edge elements (the elements with value 2^n) log will return n-1.999999999999 instead of n.0. Is this fear correct? How can I modify my statement so that it always will return a correct answer?
share|improve this question
I don't get the question. Why would it return n - 1,9(9)? – sharptooth Jun 15 '09 at 5:37
Because not all integers can be stored exactly in as a floating point number. If 7 would be not fitting, it would be stored as 7.000001 or 6.999999 for example. – Peter Smit Jun 15 '09 at 5:43
Yeap, I know that. But where has this 1,9(9) come from? Perhaps you could reformat the question using for upper indices and for lower indices? – sharptooth Jun 15 '09 at 5:49
Any integer can be stored exactly in a floating-point number. However, the log() function isn't necessarily precise, and even if it is log(2) is irrational for either natural logs or base 10, so there's no reason to expect an exact result. Given that exact results can't be guaranteed, it makes sense to worry about the exact border conditions. – David Thornley Jun 15 '09 at 14:00
You have to have pretty large integers, probably 2^exponentsize before they can't be exactly represented. If you have loss of precision in this case, it's because log(2) can't be exactly represented. Will you only ever call this method for 2^n? If so, you can round to nearest integer (or just use the accepted answer) – erikkallen Jun 15 '09 at 14:03

You can use this method instead:
int targetlevel = 0;
while (index >>= 1) ++targetlevel;
Note: this will modify index. If you need it unchanged, create another temporary int.
The corner case is when index is 0. You probably should check it separately and throw an exception or return an error if index == 0.
share|improve this answer
Does the while loop evaluate 0-integers to false? – Peter Smit Jun 15 '09 at 5:57
If index = 0, targetlevel is going to be 0. In your code it will probably cause exception. What value would you like to get for index = 0? – Igor Krivokon Jun 15 '09 at 6:02
I mean to say, the loop has to stop when index >>= 1 evaluates to 0. I couldn't find somewhere quickly that the while loop will really stop when the expression evaluates to an integer zero. It is of course logic it will, because the bits are the same then as boolean false. – Peter Smit Jun 15 '09 at 6:07
...actually, in your code it's not not exception - it will evaluate to minus infinity and then converted to int as maximum negative int value. – Igor Krivokon Jun 15 '09 at 6:07
Make sure to specify index as unsigned int, otherwise you have a very dangerous potentially infinite loop bug on your hands. – bobobobo Feb 14 '13 at 17:41
If you are on a recent-ish x86 or x86-64 platform (and you probably are), use the bsr instruction which will return the position of the highest set bit in an unsigned integer. It turns out that this is exactly the same as log2(). Here is a short C or C++ function that invokes bsr using inline ASM:
_TAG_
static inline uint32_t log2(const uint32_t x) {
 uint32_t y;
 asm ( "\tbsr %1, %0\n"
 : "=r"(y)
 : "r" (x)
 return y;
share|improve this answer
And on ARM you'd want clz, which returns 31 minus the value you want. GCC has __builtin_clz, which presumably uses bsr on x86. – Steve Jessop Jun 15 '09 at 11:44
That is a really great answer – bobobobo Feb 14 '13 at 17:46
To avoid the subtraction, use __builtin_ctz instead. int log2 (int x){return __builtin_ctz (x);} It also works on x86. – user2573802 Sep 8 '13 at 16:43
_USER_ This is wrong. __builtin_ctz(9) = 0 which is not log2(9). – nixeagle Oct 11 '13 at 1:52
Oh, I remember now. It's finding the lowest-order bit that's set, so it only works for numbers which are exact powers of two. The first bit (bit 0) is set for 9 (1001), so it returns 0. – user2573802 Nov 25 '13 at 1:35
If you just want a fast integer log2 operation, the following function will do it without having to worry about floating-point accuracy:
static unsigned int mylog2 (unsigned int val) {
 unsigned int ret = -1;
 while (val!= 0) {
 val >>= 1;
 return ret;
It will return -1 for an input value of 0, rather than the correct infinity (which is a little hard to represent in an integer :-)
By the way, there are some insanely fast hacks to do exactly this (find the highest bit set in a 2's complement number) available from here. I wouldn't suggest using them unless speed is of the essence (I prefer readability myself) but you should be made aware that they exist.
share|improve this answer
paxdiablo — I like that you're returning –1 for an input value of 0. Note, however, that you aren't actually returning -1, but actually instead ~0 (e.g., 0xFFFFFFFF if you have 32-bit integers), since you've declared the function to return an unsigned int rather than int. In this sense, ~0 is the closest to infinity that you can get in an integer. – Todd Lehman Jul 21 '14 at 18:31
Base-2 Integer Logarithm
Here is what I do for 64-bit unsigned integers. This calculates the floor of the base-2 logarithm, which is equivalent to the index of the most significant bit. This method is smokingly fast for large numbers because it uses an unrolled loop that executes always in log₂64 = 6 steps.
Essentially, what it does is subtracts away progressively smaller squares in the sequence { 0 ≤ k ≤ 5: 2^(2^k) } = { 2³², 2¹⁶, 2⁸, 2⁴, 2², 2¹ } = { _PHONE_, 65536, 256, 16, 4, 2, 1 } and sums the exponents k of the subtracted values.
int uint64_log2(uint64_t n)
 _TAG_ S(k) if (n >= (UINT64_C(1) << k)) { i += k; n >>= k; }
 int i = -(n == 0); S(32); S(16); S(8); S(4); S(2); S(1); return i;
 _TAG_ S
Note that this returns –1 if given the invalid input of 0 (which is what the initial -(n == 0) is checking for). If you never expect to invoke it with n == 0, you could substitute int i = 0; for the initializer and add assert(n!= 0); at entry to the function.
Base-10 Integer Logarithm
Base-10 integer logarithms can be calculated using similarly — with the largest square to test being 10¹⁶ because log₁₀2⁶⁴ ≅ 19.2659...
int uint64_log10(uint64_t n)
 _TAG_ S(k, m) if (n >= UINT64_C(m)) { i += k; n /= UINT64_C(m); }
 int i = -(n == 0);
 S(16,10000000000000000); S(8,100000000); S(4,10000); S(2,100); S(1,10);
 return i;
 _TAG_ S

Very pretty. With a decent compiler and the right instruction set, the conditional actions might all be implemented as predicated instructions, so there are no branch mispredicts; it is all pure computation in the registers at the (superscalar) rate the typical modern processor can achieve. – Ira Baxter Aug 9 '14 at 17:03

at Stonegate Farm
at Stonegate Farm
Stonegate Farm is a nineteenth-century estate farm in New York's picturesque Hudson River Valley. Located one-hour north of New York City, the historic carpenter-gothic farm is a model of bio-intensive organic farming where growing and cultivating is practiced as an art form, where healthy and sustainable land-stewardship is prioritized, and where ideas on the value, meaning and processes of small-scale, sustainable farming are passionately explored. The farm's philosophy is manifest in the cultivation of its beauty and wellness products, its various food and event programs, and its public outreach as a model of aspirational growing.
The farm cultivates a seasonal abundance of medicinal and culinary herbs, botanicals for topical and ingestible beauty and wellness, as well as historic tree and bramble fruit, vegetables and raw honey. Our methods are organic and sustainable, with no chemical fertilizers or pesticides in practice. Our soil is regularly replenished with local compost, minerals and low-impact, cultivation. Though herbs and flowers are the farm's priority, it's Stonegate's diverse and varied ecosystem of living things that is essential to the harmonic balance and interaction of soil and plant health, as well as to the efficacy of the farm's products and services.
We are Jill Rowe and Matthew Benson, co-founders of Cultivate Apothecary at Stonegate Farm and blissed-out stewards of this magical and productive piece of earth. We and our amazing team at Stonegate Farm are passionate about creating the most beautiful and potent botanical beauty and wellness products for you. We care as much about the impact and efficacy of what we create for you, as we do the impact we impress on our environment. We are multi-passionates–with past lives in publishing, film, fashion, photography, art, food, horticulture, and beauty–but mostly we are compulsive creative obsessives with never enough hours in the day.

Engelberg Monastery 900th Anniversary
When monks arrived in this region in the High Middle Ages, it is said that they were greeted by singing angels. This is where Engelberg Monastery, founded in 1120, and the nearby town get their name. The prominent mountain, where the singing was heard, is now called Hahnen and is Engelberg's local mountain. Ever since it was founded, the Benedictine monastery has shaped the history of the high valley. Following the founding of the Engelberg writing school in the mid-1100s, it has played a leading role in education, and today, it has its own training campus. The current monastery building was built after its third fire in 1729 and is one of the largest baroque buildings in Central Switzerland. The monastery's church is in fact also a parish church. In the western gallery, you will find the organ. With its 9097 pipes distributed across 137 stops, it is the largest organ in Switzerland and one of the largest in the world.

AbstractIn this paper, we propose optimal linear detectors for non-orthogonal amplify-and-forward cooperative protocol when considering a single-relay scenario. Two types of detectors are proposed based on the principles of minimum mean square error (MMSE) and minimum bit error rate (MBER). The MMSE detector minimizes the mean square error, while the MBER minimizes the system bit error rate (BER). Both detectors exhibit excellent BER performance with relatively low complexity as compared to the maximal likelihood (ML) detector. The BER performance of both detectors is superior to the channel inversion, the maximal ratio combining, and the biased ML detectors. © 2013 IEEE.

A video letter is a communication tool allowing people to connect with communities around the world. Video letters can take the form of a "postcard"– small video snapshots intended to be sent from one community to another, or to advocate for a specific social cause. It can also take the form of a full length "Video Letter" that more closely resembles a media advocacy piece or short form documentary. Both provide a simple, but powerful, framework for self-representation.
Youth media, and more specifically the video letter, has the following goals:
1. To Inspire youth to reflect about themselves, their communities and the world.
2. To inspire leadership and advocacy within their communities.
3. To provide the media tools and platforms (as an alternatives to mainstream media) to share their stories and raise awareness about their communities and cultural identities.
4. To open up communication and understanding between communities where physical dialogue is difficult.
5. To empower youth to become advocates for social change, and proud members of strong communities.
A video letter is a youth friendly media advocacy tool that fosters self-representation and empowerment. These films afford an opportunity for communities to provide inside perspectives that are often under-represented, overlooked or ignored by mainstream media.
Video letters are made through a series of workshops where youth are taught basic film production and journalism along with human rights and advocacy concepts including the rights of the child as declared by UNICEF in the Convention on the Rights of the Child (CRC).
It is a relatively accessible and affordable means to self represent. All that is needed are cameras, a computer with Internet access and an interest in creating youth media.
After the film is made, it can be shared with communities around the world. We often use the video letters in workshops as an example and to inspire communication between two or more communities. These films are also highlighted on this website– a nodal point for all the video letters which together will be a powerful manifestation of the Convention on the Rights of the Child.

The operators of the hydroelectric dam near the Newport Avenue Bridge began drawing down the water level in Mirror Pond on Monday to allow for maintenance work on the dam.
The project should take about two weeks, according to a news release from PacifiCorp, the company that owns and maintains the dam.
The utility said it intends to lower Mirror Pond about 7 feet in order to bring in equipment to install panels along 20 feet of the upstream side of the 250-foot dam. The panels are intended to reduce water leakage through the dam, allowing for more effective regulation of the water level in Mirror Pond.
Built in 1910, the dam was added to the PacifiCorp generation system in 1930. It produces 1 megawatt of electricity, roughly enough to power 450 average homes, according to Tom Gauntt, spokesman for PacifiCorp.

Kintu created the kingdom of Buganda by forcefully taking over the five clans that lived in the region. To signify his victory over a clan, he would sleep in the conquered leader's home; tradition says that Buganda was the name of the first house that he slept in after his victory over Bemba and his tribe. Buganda was later used to refer to the entire area he subdued.
Kintu Kato is not to be confused with Kintu, the first person on the earth according to Buganda legend. Kato Kintu gave himself the name Kintu, a name that he knew the Baganda associated with the father of all people.

In 1890, the Board of Trustees commissioned Merry L. Pence to survey prospects for a campus lake. The early campus catalogs describe the university lake as deriving from the "natural conformation of the ground and an abundant supply of water from the Maxwell Spring." These two things rendered the construction of an artificial lake with a boating course a quarter of a mile in length, "thus providing for a beautiful sheet of water to add to the attractions of the landscape." It was six feet deep at the Limestone Street end and three feet deep at the other.
|Barker Hall, left and the Main Building, right.|
In the summer, students boated on the lake and in the winter, they ice skated. But by 1917, the lake had become an eyesore for the campus and it had essentially become a swamp. Discussions by the Board of Trustees to either restore it as a lake or turn it into a botanical garden ensued. The problem was resolved in the 1920s during preparation of the ground for building the Alumni Gymnasium and McLean Stadium.

Keenan and Lower Richland High Schools Salad Bar Kick-Off!!
Student Nutrition Services will kick-off Salad Bars at both Keenan and Lower Richland High Schools kick-off on Monday, February 17th. Both schools are the recipients of the salad bars donated to the Richland One School District by Whole Foods. This program is part of the Let's Move Salad Bars to Schools national campaign that connects donors and schools with the goal of giving away free salad bars. All schools-both public and private-that participate in the National School Lunch Program are eligible.
Let's Move Salad Bars to Schools is a comprehensive grassroots public health effort to mobilize and engage stakeholders at the local, state and national level to support salad bars in schools. Their vision is to significantly increase salad bars in schools across the country until every child has the choice of healthy fruits and vegetables every day at school. Let's Move Salad Bars to Schools is an initiative of the Food Family Farming Association Foundation, National Fruit and Vegetable Alliance, United Fresh Produce Association Foundation and Whole Foods Marketto support First Lady Michelle Obama's Let's Move! initiative. The goal of the Let's Move Salad Bars to Schools program is to fund and award 6000 salad bars over the next three years.
Why salad bars?
· Kids eat more fruits and vegetables when they have choices. Since most children are not eating enough fruits and vegetables on a given day, salad bars are a great opportunity to help them meet their nutritional needs.
· Kids who eat a balance and nutritious diet are better learners.
· Kids learn to make decisions that carry over outside of school, providing a platform a lifetime of healthy snack and meal choices.
· Salad bars are a perfect place to showcase fresh foods from your local farmer, which is good for the farmer and good for the local economy
