Tech Insight Data Centre Management: Trends and Challenges
Data Centre Management in the U.S. and China: Trends and Challenges
Business and technology decision makers often focus on factors such as performance and uptime when investing in new solutions. However, as the amount of data that companies collect grows, organisations have had to place more emphasis on a larger number of factors than they have in years past. Seagate surveyed data centre managers throughout the United States and China to explore the most prominent issues facing facility decision makers.
The Seagate Data Centre Manager study polled 651 respondents, who were screened based on several qualification criteria. Those polled had to have IT management responsibilities and work in their organisation's data centre (with a minimum of 50 servers or 100 terabytes of storage). In addition, individuals had to have some responsibility over storage devices. Below is a summary of the study's key findings:
 - Security is a top priority and challenge for both regions.
 - Time-consuming drive management activities represent the largest storage-related pain point.
This report will explore the key issues that data centre managers face, as well as how storage relates to common challenges associated with running a facility. However, it is necessary to first understand general data centre growth and budget trends.
Data Centre and Data Growth Trends
As many businesses place greater demands on their IT departments to spur innovation and generate new efficiencies, it makes sense to first look at the issue of facility budgets. The good news is that a majority of data centre budgets are expected to increase over the next year. This is countered by the fact that storage capacity demand is expected to grow at approximately double that rate. Below is a breakdown of how respondents plan to accommodate expanding data growth.[see Datat Growth Strategies chart below]
The most commonly cited strategies involved new investment; the majority of data centre operators in both regions planned to purchase new hardware, while replacing or upgrading existing solutions was the second highest response. However, fewer respondents (30%) planned to hire new employees to manage these assets, suggesting that they will likely turn to the hardware and software to ease the burden of management. This is also reflected in the most common storage pain points, which are focused on drive management activities.
Although respondents in China tended to be more likely to have new investments planned, some of this may be due to differences in budget growth. While the amount of increase was similar for both regions, more respondents in China (75%) expected larger budgets than those in the United States (54%). This gap may also help to explain some of the key differences in concerns among data centres in the two regions.
Data Centre Operators: Key Concerns and Top Priorities
Managing the modern data centre presents a myriad of challenges, and managers are feeling pressure due to a number of different factors. While there were some regional differences in this area, one factor was prevalent in both countries. When asked to identify the top three challenges for their data centres in 2013, security topped the list with 31% of all survey respondents ranking it the highest. {see Challenges (Top 10) chart below}
Interestingly, data security was ranked below system performance and staff issues for U.S. respondents as a top challenge, but this group ranked improving security as a first priority.
Hardware management presented another top challenge for organisations, but some of the reasons for this difficulty were different depending on region. For instance, U.S. respondents were more likely to cite staffing issues as a top challenge, while data centre operators in China expressed frustration with infrastructure complexity. The difference can likely be attributed to the lower frequency of budget growth in the former. However, both of these problems suggest a heightened demand for streamlining management activities. A limited number of employees will ultimately impact the ability to detect and prevent issues, while the issue of complexity can make it difficult even for a large staff to operate efficiently.
In addition to challenges, Seagate asked respondents what their data centre's top three priorities were for 2013. There was some overlap in the area of security, which garnered the highest number of responses. However, this question also raised new issues and presented some significant regional differences. For example, data centre operators in the United States (28%) placed more emphasis on reducing cost than those in China (19%).
The other top priorities for data centres in China were to increase agility and consolidate operations. This may be a reflection of frustration with infrastructure complexity, as it can become more difficult to incorporate new technologies when the IT ecosystem consists of so many moving parts. Similarly, the focus on operational consolidation suggests that emphasis is placed on improving efficiency to deal with expanding data volume.
It is also worth noting that these issues are not entirely separate. While U.S. respondents were more likely to deal with constrained budgets, the activities associated with data centre consolidation would likely produce cost benefits, whether they stem from lower hardware costs or fewer staff hours spent managing devices. In other words, motivations for doing so may differ, but addressing the core challenges of data centre operation is likely to achieve comparable results.
Data Security: A Detailed Look
The importance of protecting information stored in data centres has risen in prominence alongside news of high-profile breaches. Given that it is a top priority for both regions, it may be helpful to take a closer look at this problem in particular.
Security in general has been climbing executive agendas due to three main factors: mobile security, big data and advanced targeted attacks.
Although not all of those issues are storage problems, the mention of big data does corroborate the notion that expanding volume and complexity plays a role in making data centre security more stressful. In addition, the emergence of targeted attacks makes it more important to protect data in transit, while stored on active drives and after devices have been retired.
InformationWeek's 2013 Strategic Security Study revealed another layer of complexity to the issue. Although the IT industry pays a lot of attention to external attacks, organisations are comparably worried about malicious insiders. When asked about the greatest security risks they face, 53% of respondents said cyber criminals, while 51% cited authorised users.
Fortunately, the Ponemon Institute's 2013 IT Security Tracking Study found that senior-level IT professionals were well aware of the need for comprehensive security {see Important Technologies for Combating Security Risk chart below}. Encryption for data at rest was rated as the third most important technology for mitigating risk, behind security intelligence and access governance systems. Considering that more than 50% of respondents rated numerous solutions as important, businesses have recognised the need for a multifaceted strategy to address this problem.
One potential issue that could arise from utilising numerous solutions is difficulty in managing them. For example, employing encryption for data at rest can be a cumbersome and time-consuming process, particularly if the organisation does not have an information governance strategy in place.
The Issue of Storage
Rapid data growth and increasing demand for capacity place storage at the heart of many data centre challenges. Particularly as enterprises collect and generate larger amounts of information, understanding the issues affecting storage can lead to significant improvements in overall data centre management activity. {See earlier Data Growth Strategies chart}
The leading strategy for accommodating data growth is to purchase new storage solutions, cited by 60% of respondents. This is followed by hardware replacement at 55%, suggesting a dynamic storage ecosystem in most data centres as drives are retired and new hardware is purchased. Despite the rapid rate of change in the average storage environment, fewer respondents (30% of those polled) planned to increase staffing.
This means that data centre operators worldwide will likely have to follow the "do more with less" paradigm that has become prevalent in resource-strapped organisations. The other issues facing data centres, such as existing staffing difficulties in the United States, means that managers would benefit from adjusting storage management practices and vendors will need to implement solutions that streamline drive management activities. For example, one prominent concern regarding ageing drives is that older hardware is more likely to fail and may experience performance degradation. However, retiring drives too early will result in higher total cost of ownership. In this case, it may be beneficial to adopt performance analytics software to ensure drives are working optimally and to use predictive analysis to identify potential failures before they disrupt operations.
Conclusions and Recommendations
As the research shows, data centres face a number of challenges that can all affect total cost of ownership and the difficulty of managing their hardware. Businesses are expected to continue generating large volumes of information, and addressing that data growth requires a comprehensive strategy that makes strategic purchases while maximising those investments.
It is important to consider total cost of ownership from both a process and a technological perspective. While storage hardware management represents a core concern among data centre operators, organisations would also benefit from making these tasks more efficient. For context, Payscale.com lists the median hourly rate for a data centre technician as US$26.11, and Seagate research revealed the five most time-consuming storage drive activities:
 - Monitoring or analysing devices (2.09 hours)
 - Troubleshooting drives (1.46 hours)
 - Improving drive management processes (1.25 hours)
 - Researching new solutions (1.24 hours)
 - Training new staff on procedures (1.22 hours)
** Average hours spent per drive management employee (per week)
Three of those activities are directly related to daily management tasks, meaning that organisations would see an immediate reduction in total cost of ownership by improving operational efficiency. For example, a 20% reduction in drive monitoring and analysis time alone would save US$44 per drive management employee per month. The savings would be even greater if carried out across other key activities, and improving some processes would likely create widespread benefit.
The hardware itself can also play a role in how efficiently tasks can be completed, so it is important to consider the impact of IT investments. Data security serves as a good example. Technology that makes it easier to encrypt stored data would make the process itself faster while mitigating the risk of

FOR IMMEDIATE RELEASE
December 13, 2012
When Where You Live May Determine If You Live
Rural dwellers less likely to follow cancer screening guidelines
SALT LAKE CITY— People who reside in rural areas of Utah are less likely to follow colorectal cancer (CRC) screening recommendations than their urban counterparts, according to researchers from Huntsman Cancer Institute (HCI) at the University of Utah. This geographic disparity is evident across all risk groups, including those who have a family history of the disease.
"Our hypothesis was that geography matters," said Anita Kinney, Ph.D., R.N., who leads HCI's Cancer Control and Populations Sciences Research Program and is principal investigator of the study. "And what we found is that it does indeed matter."
Kinney is a professor in the Department of Medicine at the University of Utah, a Jon and Karen Huntsman Presidential Professor in Cancer Research, and an HCI investigator. The research team's findings are reported in an article appearing in the current issue of the journal Clinical Gastroenterology and Hepatology.
"Other studies have confirmed differences in health care behaviors between urban and rural residents. Ours is the first study to examine the influence of distance from, and availability of, CRC screening providers on the use of risk-appropriate screening among urban and rural dwellers," Kinney said.
American Cancer Society screening guidelines for patients with a family history of CRC recommend earlier and more frequent testing. Individuals with a parent, sibling, or child diagnosed with the disease when less than 60 years old are considered at high risk and should begin colonoscopy screening at age 40, or 10 years before the youngest age of diagnosis in the immediate family, whichever is earlier, and continue at five-year intervals.
Kinney's team analyzed data from the Behavior Risk Factor Surveillance System, a set of telephone surveys coordinated by the Centers for Disease Control and state health departments. The survey routinely includes questions about cancer screening, but not about familial CRC history. Working with the Utah Department of Health, the research team added questions concerning family history of CRC that indicated whether increased familial cancer risk was present.
"One fact that gets overlooked in addressing compliance with screening recommendations is the amount of time required for a person to obtain the appropriate screening," said co-author Kevin Henry, Ph.D., an HCI investigator and assistant professor in the Department of Geography at the University of Utah. "With the longer distance travelled, a person may need to set aside a day or more from regular activities for preparations and travel as well as the procedure itself."
Other problems for rural residents may compound the problem, the researchers said. One is that rural residents are less likely to have health insurance that pays for cancer screening. Kinney pointed out that "preventive services such as cancer screening are covered in the Affordable Care Act, and this should increase the number of people who get regular screening."
Another problem, according to the researchers, is that rural dwellers are less likely than urban dwellers to receive a recommendation for CRC screening from a health care provider, which may be due to primary care provider shortages and provider time constraints.
"We know that CRC screening saves lives. The more people screened, the more lives we save," Kinney said.
Other co-authors on the study include Allison E. Anderson, M.P.H., and N. Jewel Samadder, M.D., of HCI, and Ray M. Merrill, Ph.D., M.P.H. of Brigham Young University. Financial support for this study was provided by the Huntsman Cancer Foundation, and grant numbers CA125194 and CA042014 (CCSG) from the National Cancer Institute of the National Institutes of Health.

Analysis and Synthesis of Head Motionfor Life like Conversational Agents
Kawamoto, Shin ichi
Hofer, Gregor O
MetadataShow full item record
This study aims to investigate which and what motions of lifelike conversational agents play essential role to make the agents natural. Some preliminary experimental results and future plan are shown. Embodying conversational agents is intended to imitate paralinguistic channel or back channel which plays important role in human-human conversation. Although there have been not a few lifelike conversational agents developed, appearance and behaviour of the agents are far from being natural, and merits of embodying have not been realized that much. One of the main reasons is the lack of natural motions of the agents, including the motion of head, mouth, eyes and eye brows. To improve the quality of these motions, several pioneering works have been reported [1–3]. To tackle the problem, the present study was started conducting a subjective test of head motion and analysis of head motion using signal processing techniques.

More 60-Second Science
What does an 800-pound gorilla eat? If you said: "anything it wants," you're not thinking like a scientist.
A scientist would say, "Let me analyze the isotopic composition of its excreta and I'll get back to you." Because a new study shows that the ratio of carbon isotopes found in mountain gorilla feces reveals how much fruit the apes have consumed. The scoop's in the latest issue of the Proceedings of the National Academy of Sciences. [Scott A. Blumenthal et al., Detecting intraannual dietary variability in wild mountain gorillas by stable isotope analysis of feces]
Knowing what animals nosh on in the wild and how that diet fluctuates can offer a key to their health and the overall health of the species. But not all beasties like to dine al fresco, at least not where scientists can watch. So researchers decided to reach for the scat.
As a test case they focused on four mountain gorillas in a park in Uganda, because they could actually see what these apes ingested. Different plants have different ratios of carbon's common isotopes. So for 10 months the researchers measured the carbon in the plants that went into the gorillas and then what came back out.
And they found that the dung don't lie, at least when it comes to what's been on Koko's menu.

Accessing containers
For accessing the values inside containers:
 - Struct<>, Tuple<> and Variant<>, use a dot. The set of keys (for the tuple and the corresponding variant — indexes) is known at the query compilation time. The key is validated before beginning the query execution.
 - List<> and Dict<>, use square brackets. The set of keys (set of indexes for keys) is known only at the query execution time. The key is not validated before beginning the query execution. If no value is found, an empty value (NULL) is returned.
Description and list of available containers.
When using this syntax to access containers within table columns, be sure to specify the full column name, including the table name or table alias separated by a dot (see the first example below).

Putting Faulty Cores to Work
Since the non-cache parts of a core are less regular, compared to on-chip caches, tolerating manufacturing defects in the processing core is a more challenging problem. Due to the lack of effective solutions, disabling non-functional cores is a common practice in industry, which results in a significant reduction in system throughput. Although a faulty core cannot be trusted to correctly execute programs, they observe that for most defects, when starting from a valid architectural state, execution traces on a defective core coarsely resemble those of fault-free executions. In light of this insight, the authors propose a robust and heterogeneous core coupling execution scheme, Necromancer that exploits a functionally dead core to improve system throughput by supplying hints regarding high-level program behavior.


warning C28616: Multithreaded AV condition
In a multithreaded environment, it is impossible to know when a thread is preempted, with the consequence that the apparent effect of reducing the reference count of an object is that it is deleted without further action on the part of the current thread. There should be no access to a reference-counted object after the reference count could potentially be at zero.
The following is an example of threading time sequence that could expose this problem:
A thread T1 executes lines 1, 2, and 3, decrements m_cRef to 1, and is preempted.
Another thread T2 executes lines 1, 2, and 3 decrements m_cRef to 0. Then it executes lines 4 and 5, where this is deleted, and finally executes line 6.
When T1 is rescheduled, it will reference m_cref on line 9. Thus it will access a member variable after the related this pointer has been deleted—and when the heap for the object is in an unknown state.
 1 ULONG CObject::Release()
 2 {
 3 if ( 0 == InterlockedDecrement(&m_cRef) )
 4 {
 5 delete this;
 6 return NULL;
 7 }
 8 /* this.m_cRef isn't thread safe */
 9 return m_cRef;
 10 }
The corrected example does not reference any heap memory after the object is deleted.
ULONG CObject::Release()
 ASSERT( 0!= m_cRef );
 ULONG cRef = InterlockedDecrement(&m_cRef);
 if ( 0 == cRef )
 delete this;
 return cRef;

What they needed
The Cornell High Energy Synchrotron Source (CHESS) is a high-intensity X-ray source primarily supported by the National Science Foundation, which provides state-of-the-art synchrotron radiation facilities for research in various physical sciences.
CHESS needed a complex online reporting and management system for accepting and reviewing proposals from users around the world, as well as scheduling beamtime and tracking user visits.
Our custom software solution
GORGES created a custom web application using the Yii PHP framework, which incorporates several key features:
- User registration and profile editing, to track demographics and changing institutional affiliations
- Proposal submission interface for users – including detailed information on scientific approach, funding sources, and related publications
- Tools for CHESS staff to review and approve proposals based on scientific merit and safety concerns
- Interactive scheduling tools to coordinate availability of beamline stations and other resources
- Check-in interface to allow operators to track user visits and radiation safety badges
- Tools to support CHESS's reporting requirements to its various funding agencies
We are continually adding features and refactoring the application to meet CHESS's needs, while also keeping it compatible with current web standards. The application has been in production use for more than five years – which is an eternity in Internet Time. One of our major upgrades was adding responsive layout via the Bootstrap CSS framework, to support mobile devices.

Published by Peter Boler on November 10, 2020
In part one of this series, I pointed out that in times of economic downturns, like we are seeing with COVID-19, the natural tendency is to reduce if not eliminate the level of investment in new technologies and methodologies – an obvious approach to dealing with economic uncertainty. However, while this is viable over the short term, the reality is that all businesses have to re-evaluate their operational priorities to ensure they emerge from the crisis in a better position to deal with new economic realities. For many laboratory-dependent organizations, this means looking for ways to become more efficient, perhaps even increasing throughput while spending less, but still generating accurate results.
I want to dig a little deeper into the advantages of the VUV Analyzer™ Platform for Fuels as it relates to improvements in operational efficiency and long-term cost reduction.
Let's start by looking at the platform itself. The VUV Analyzer Platform for Fuels is designed to analyze different fuel types (Figure 1), with no changes in hardware or setup. This is significant because it means you can easily switch between gasoline (ASTM D8071), jet fuel (ASTM D8267) and diesel/biodiesel (ASTM # Pending).
Table 1 highlights the traditional analytical techniques and methods used for the analysis of these different fuels. Depending on what you are trying to achieve, you will need to run multiple samples on different analytical techniques. From an efficiency standpoint, this requires a lot of time and depending on the techniques, significant expertise. Since the VUV Analyzer Platform is automated and uses a single column, there is minimal impact to productivity when switching between analysis types. This allows you to consolidate fuels analysis to a single platform while increasing the efficiency of the analyst. Ultimately you can increase analytical throughput with fewer analytical techniques. But what about cost?
Logically, it would make sense that reducing the number of analytical techniques would have a dramatic impact on cost. In part 1, I showed that when using the VUV Analyzer Platform for Fuels running ASTM D8071, you could reduce the cost-per-analysis from approximately $64.63 USD per sample to $5.21 USD. For jet fuel (Figure 2), cost-per-analysis can be reduced to $3.07 USD per sample compared to FIA (ASTM D1319) at $51.49 USD, and HPLC (ASTM D6379) at $8.98 USD per sample. How is this possible?
The answer is not all that complicated and takes into account three different variables: cost-of-acquisition, cost-of-maintenance and consumables, and cost-of-labor. Let's consider each:
Usually the cost to acquire the hardware gets the most attention as it is the upfront cost needed. Depending on the instrumentation required, it can be inexpensive like FIA or more expensive like GC-MS. To be fair implementing the VUV Analyzer Platform does require more capital investment compared to other techniques, which is reflected in Figure 2 with a higher cost-per-sample on the capital line. It is important to note that the number is greatly influenced by whether or not the VUV Analyzer hardware is being added-on to an existing GC (which reduces the capital requirement) or a new GC. However, the capital investment is only a small part of the story.
Cost-of-Maintenance and Consumables
Consolidating from multiple analytical techniques reduces the number of instruments in the lab. This means less maintenance and consumables cost over time. Simply put, using the VUV Analyzer Platform reduces the number of GCs and gas consumption, eliminates expensive consumables like platinum reactors used in GC-OFID, eliminates the need for ion source cleanings and expensive deuterated standards. Additionally, there are no expensive dyes (FIA) or hazardous solvents like those used in HPLC. The VUV Analyzer Platform has one consumable – a lamp that only needs to be replaced every 2000 hours. To put this in perspective, one user of the VUV Analyzer Platform running ASTM D8071 and D8267 has calculated that they will save approximately $125,000 USD per year (excluding labor) by replacing the other techniques with the VUV Analyzer Platform.
The last variable is labor. Any discussion of labor cost almost always revolves around reduction. However, when I refer to reducing the cost-of-labor, I am actually referring to better utilization of existing resources as opposed to the elimination of that cost. Simply put, since the VUV Analyzer Platform eliminates the need for multiple analytical techniques, is automated and calibration free, and does not require any changes in hardware or setup when changing between fuels types, laboratory resources can be utilized on other high priority projects – which means more productivity.
As discussed in part 1, in times of economic uncertainty, it is usually capital expenditures which get delayed or eliminated first. Laboratories that look to eliminate long-term recurring costs first are often better positioned to emerge from economic uncertainties. Strategic capital investments that have a positive impact on reducing operating costs and generating operational efficiencies over the long term are critical to future success.

Taking and Comparing Screenshots
You can take and compare screenshots with reference screenshots taken earlier. If there are differences, you can fail the test case.
Screenshot Parameters
The screenshot configuration parameters are defined with static methods in the com.vaadin.testbench.Parameters class.
screenshotErrorDirectory(default: null)
Defines the directory where screenshots for failed tests or comparisons are stored.
screenshotReferenceDirectory(default: null)
Defines the directory where the reference images for screenshot comparison are stored.
screenshotComparisonTolerance(default: 0.01)
Screen comparison is usually not done with exact pixel values, because rendering in browser often has some tiny inconsistencies. Also image compression may cause small artifacts.
screenshotComparisonCursorDetection(default: false)
Some field component get a blinking cursor when they have the focus. The cursor can cause unnecessary failures depending on whether the blink happens to make the cursor visible or invisible when taking a screenshot. This parameter enables cursor detection that tries to minimize these failures.
maxScreenshotRetries(default: 2)
Sometimes a screenshot comparison may fail because the screen rendering has not yet finished, or there is a blinking cursor that is different from the reference screenshot. For these reasons, Vaadin TestBench retries the screenshot comparison for a number of times defined with this parameter.
screenshotRetryDelay(default: 500)
Delay in milliseconds for making a screenshot retry when a comparison fails.
For example:
@Before
public void setUp() throws Exception {
 Parameters.setScreenshotErrorDirectory(
 "screenshots/errors");
 Parameters.setScreenshotReferenceDirectory(
 "screenshots/reference");
 Parameters.setMaxScreenshotRetries(2);
 Parameters.setScreenshotComparisonTolerance(1.0);
 Parameters.setScreenshotRetryDelay(10);
 Parameters.setScreenshotComparisonCursorDetection(true);
 Parameters.setCaptureScreenshotOnFailure(true);
}
Taking Screenshots on Failure
Vaadin TestBench can take screenshots automatically when a test fails. To enable the feature, you need to include the ScreenshotOnFailureRule JUnit rule with a member variable annotated with @Rule in the test case as follows:
@Rule
public ScreenshotOnFailureRule screenshotOnFailureRule =
 new ScreenshotOnFailureRule(this, true);
Notice that you must not call quit() for the driver in the @After method, as that would close the driver before the rule takes the screenshot.
The screenshots are written to the error directory defined with the screenshotErrorDirectory parameter. You can configure it in the test case setup as follows:
@Before
public void setUp() throws Exception {
 Parameters.setScreenshotErrorDirectory("screenshots/errors");
 ...
}
Taking Screenshots for Comparison
Vaadin TestBench allows taking screenshots of the web browser window with the compareScreen() command in the TestBenchCommands interface. The method has a number of variants.
The compareScreen([classname]#File)# takes a File object pointing to the reference image. In this case, a possible error image is written to the error directory with the same file name. You can get a file object to a reference image with the static ImageFileUtil.getReferenceScreenshotFile() helper method.
assertTrue("Screenshots differ",
 testBench(driver).compareScreen(
 ImageFileUtil.getReferenceScreenshotFile(
 "myshot.png")));
The compareScreen([classname]#String)# takes a base name of the screenshot. It is appended with browser identifier and the file extension.
assertTrue(testBench(driver).compareScreen("tooltip"));
The compareScreen([classname]#BufferedImage,String)# allows keeping the reference image in memory. An error image is written to a file with a name determined from the base name given as the second parameter.
Screenshots taken with the compareScreen() method are compared to a reference image stored in the reference image folder. If differences are found (or the reference image is missing), the comparison method returns false and stores the screenshot in the error folder. It also generates an HTML file that highlights the differing regions.
Screenshot Comparison Error Images
Screenshots with errors are written to the error folder, which is defined with the screenshotErrorDirectory parameter described in Screenshot Parameters.
For example, the error caused by a missing reference image could be written to screenshot/errors/tooltip_firefox_12.0.png. The image is shown in A screenshot taken by a test run.
tt screenshot calc
A screenshot taken by a test run
Screenshots cover the visible page area in the browser. The size of the browser is therefore relevant for screenshot comparison. The browser is normally sized with a predefined default size. You can set the size of the browser window in a couple of ways. You can set the size of the browser window with, for example, driver.manage().window().setSize(new Dimension(1024, 768)); in the @Before method. The size includes any browser chrome, so the actual screenshot size will be smaller. To set the actual view area, you can use TestBenchCommands.resizeViewPortTo(1024, 768).
Reference Images
Reference images are expected to be found in the reference image folder, as defined with the screenshotReferenceDirectory parameter described in Screenshot Parameters. To create a reference image, just copy a screenshot from the errors/ directory to the reference/ directory.
For example:
$ cp screenshot/errors/tooltip_firefox_12.0.png screenshot/reference/
Now, when the proper reference image exists, rerunning the test outputs success:
$ java …
JUnit version 4.5
.
Time: 18.222
OK (1 test)
Masking Screenshots
You can make masked screenshot comparison with reference images that have non-opaque regions. Non-opaque pixels in the reference image, that is, ones with less than 1.0 value in the alpha channel, are ignored in the screenshot comparison.
Please see the ScreenshotITCase.java example in the TestBench Demo for an example of using masked screenshots. The example/Screenshot_Comparison_Tests.pdf document describes how to enable the example and how to create the screenshot masks in an image editor.
Visualization of Differences in Screenshots with Highlighting
Vaadin TestBench supports advanced difference visualization between a captured screenshot and the reference image. A difference report is written to a HTML file that has the same name as the failed screenshot, but with .html suffix. The reports are written to the same errors/ folder as the screenshots from the failed tests.
The differences in the images are highlighted with blue rectangles. Moving the mouse pointer over a square shows the difference area as it appears in the reference image. Clicking the image switches the entire view to the reference image and back. Text " Image for this run" is displayed in the top-left corner of the screenshot to distinguish it from the reference image.
The reference image and a highlighted error image shows a difference report with one difference between the visualized screenshot (bottom) and the reference image (top).
tt screenshot comparison 1
The reference image and a highlighted error image
Practices for Handling Screenshots
Access to the screenshot reference image directory should be arranged so that a developer who can view the results can copy the valid images to the reference directory. One possibility is to store the reference images in a version control system and check-out them to the reference/ directory.
A build system or a continuous integration system can be configured to automatically collect and store the screenshots as build artifacts.
Known Compatibility Problems
Screenshots when running Internet Explorer 9 in Compatibility Mode
:: Internet Explorer prior to version 9 adds a two-pixel border around the content area. Version 9 no longer does this and as a result screenshots taken using Internet Explorer 9 running in compatibility mode (IE7/IE8) will include the two pixel border, contrary to what the older versions of Internet Explorer do.

Welcome to the Global Runoff Data Centre
This is the Global Runoff Data Centre, a repository for the world's river discharge data and associated metadata.
The GRDC is an international archive of data up to 200 years old, and fosters multinational and global long-term hydrological studies. Originally established two decades ago, the aim of the GRDC is to help earth scientists analyse global climate trends and assess environmental impacts and risks. Positioned as a facilitator for exchanges between data providers and data users, the GRDC has become a focal point for international cooperation. Researchers, universities and other organisations make use of the facilities available for research programmes and projects.
The Global Runoff Database at GRDC is a unique collection of river discharge data collected at daily or monthly intervals from nearly 9000 stations in 157 countries. This adds up to around 360.000 station-years with an average record length of 40 years. The GRDC provides discharge data and data products for non-commercial applications.
The GRDC operates under the auspices of the World Meteorological Organisation (WMO) and supports research on climate variability and global change. The German Federal Institute of Hydrology (Bundesanstalt für Gewässerkunde or BfG) hosts the GRDC in Koblenz near the confluence of the Moselle and Rhine Rivers.

Cognitive Decision Entities for Cooperative Management in Networks of the Future (CoDECoM) is a collaboration project between DAI-Labor and Huawei, funded by Huawei's Innovation Research Program (HIRP). CoDECoM targets an efficient implementation of a knowledge plane based on distributed cognitive nodes and a distributed decision making solution, to address the problem of lacking efficient methods to re-configure the network for a highly dynamic environment. The project intends to design cognitive agent and converged control/management agents and to evaluate cognitive functions in the network nodes that collaborate to provide dynamic management (operation) and resource optimizations based on operator policies.
Within this research direction, CoDECoM proposes:
- A new cognitive node architecture consisting of two sub-components – The cognitive agent takes part in a distributed control process with all other agents on the end-to-end service path. It incorporates the network operator policies in making optimal decisions. The converged control/management agent implements reconfigurable routing based on the decisions of the cognitive agent.
- An efficient implementation of the knowledge plane based on a distributed peer-to-peer storage on individual network entities – Access to the knowledge plane will be through an efficient implementation of publish-subscribe paradigm. The organization of knowledge, as well as the subscription to contents will be through low-weight ontologies, which allow efficient establishment of meaning across different domains.
- A network-application interface gateway – An important part of the knowledge plane information comes from the applications. Furthermore it is important for the applications to describe their requirements to the network entities. CoDECoM's simple network API will serve for this purpose.
- A testbed on which diverse application scenarios can be tested – The node architecture and integration of CoDECoM components will be tested on a proof-of-concept demonstrator.

Technology is clearly among the most influential characteristics of a country experiencing rapid growth and development. The importance of satellite technology in improving the lives of the people cannot be underestimated. Satellite technology has made tremendous impact in enhancing agricultural productivity, security, environment, communication, geology and mining, governance, transportation, aviation, education, military etc. This study was carried out in order to determine the effect of satellites on the technological growth of Nigeria based on three aspects of satellite technology, satellite communication, satellite navigation and satellite remote sensing. To determine this, a quantitative research was carried out by administering questionnaires to experts in various fields affected by satellite technology to determine the extent to which these aspects of satellite technology have positively affected their jobs using the likert 5 ranking scale. A regression analysis of the result shows that all the aspects of satellite technology (communication, navigation and remote sensing) as a whole has made a significant impact on the technological growth of Nigeria. This significance can be attributed mainly to satellite communication. Satellite Navigation and Satellite Remote Sensing have contributed insignificantly to the technological growth of Nigeria. We therefore recommend from this study that for Nigeria to reap from the applications of satellite technology as experienced in more developed countries, more research and development to be carried out in the area of satellite remote sensing and navigation to improve on the lives of the people and for better national security.

Have you ever looked down at your pup's droppings and said to yourself "Wow, that's an odd color." Your pup's poop can come in a variety of colors, each with their own story to tell you. As a pup owner, studying your pup's poop is important to ensure that they remain healthy. So when you discover that your pup has pooped the color orange, you have to ask "what does it mean?"
Your pup's poop is naturally darker on the outside and light on the inside. A healthy pup's droppings will normally be a tan or brown color when they first unload. So if you notice that your pup has left a few orange droppings behind them, there are two possibilities to consider.
Is it something he ate?
Often times orange poop will be the outcome of certain things they ate. A change in diet or new treats can affect the tone of their droppings. Usually if the color shows up once and then disappears, it is likely that your pup's diet has changed, or perhaps even a neighbor has slipped them a treat.
If your pup's droppings are dark orange or continuously orange in color, this may be signs of intestinal problems. Some infections can cause internal bleeding, and though most times a pup's poop will be black or extreme brown when this happens, bleeding in the lower intestines can lead to fresh blood in the stool, giving it an orange color. Along with infections, parasites such as worms can also damage your pup's digestive track. If you suspect that this is a problem, take your pup to the vet immediately.
Remember to always keep track of your pup's poop, whether on walks, in the yard or in their litter box. Droppings come in all different sizes and consistencies, so those must also be factored into your analysis. You don't want to jump to conclusions, but it is always better to be safe than sorry.
So next time you take your pup out for their daily walk, stop and check out their droppings, (you should pick it up to be polite to your neighbor too) and make sure that your pup's health is in tip-top shape.

Life rafts are an important safety requirement on ships. In their absence, marine fatalities could occur which otherwise could have been prevented. Ships, large boats, and other marine vessels incorporate the usage of life rafts, making them indispensable in the nature of marine vessel operations.
Like any equipment, even life rafts require periodic servicing and maintenance.
- Constant usage during drills or previous emergencies can render the life raft weather worn which could cause problems at the time of emergencies.
- The inflation system of the raft could have problems and the lack of the same could pose problems during exigency situations.
- There are a few necessary instrumentations that are stored in the life rafts for using as and when the situation arises. The lack of workability of these equipments necessitates life raft servicing.
Life raft repair services do not just mean repairing and servicing the rafts. They include proper prior inspection and monitoring carried out by qualified technicians. Generally, the inspection of the rafts for any problems or damage is prescribed to be carried annually. A regular yearly monitoring of the life raft ensures longevity of its usage for a considerable span of time.
However, the professionals in-charge of the life raft maintenance operations need to possess a few requirements that would certify them to be proficient to carry out the required maintenance work. These requirements can be specified as follows:
- The technicians need to have a certification allowing them to carry out the repairing operation. The validity of the aforesaid certificate however, is only for a period of three years. Therefore it becomes a primary requirement to ensure that a technician's certification of life raft servicing is valid for the current time period.
- The service centre needs to be as per the appropriate marine industry standards. The absence of a certified service centre would make the repairing services redundant and cause a person to incur further damages and problems.
- The service centre for life rafts needs to be chosen as per the stipulations of the authority sanctioning the usage of the rafts. In case of any discrepancy between the raft sanctioning body and the life rafts servicing centres, there could be unwanted problems for a person getting the necessary repairs carried out.
- Thorough inspection of the external case of the life raft is carried out followed an equally thorough inspection of the raft
- The inflation of the raft with respect to pressure, its maximum inflation capacity, the toughness of the raft material and the stitches is thoroughly monitored and recorded
- Instrumentations and gadgets stored in the raft are monitored for their date of expiry. A very important gadget necessitating a careful and meticulous monitoring is the cylinders used for the purpose of the raft-inflating gas.
- Following the completion of the monitoring, the technicians have to follow the standard protocol while re-folding the life rafts. The prescribed protocols differ as per the requirements of the makers of the rafts and a strict adhering to the re-folding aspect needs to be maintained.
- Rafts as per USCG and SOLAS standards mandatorily require a ten-yearly servicing inspection a few specific areas that raft owners need to comply with. In addition to these servicing requirements, the owners of USCG and SOLAS standard rafts also need to carry out a five-yearly servicing inspection for the overall system of gas inflation of the rafts.
- Following the completion of the life raft repair services, the required certifications are issued to the owners while records of the monitoring carried are meticulously maintained. These processes ensure a complete transparency in the procedure, which helps to avoid complications.
There are many authentic and established service centres where life raft repair services are carried out. These service centres state their standards of carrying out the life raft repairing operations leaving no doubt about their authenticity to a person.

Residents are advised to continue conserving water, as rationing may resume in mid-2024.
The current water supply in catchments can last six months, contingent on receiving adequate rainfall to replenish them.
Beyond that, if there's no runoff by June next year, a return to conservation measures is likely. Potworks Dam currently supplies about 9 percent of the local demand, with 700,000 gallons daily.
The Delaps Water Treatment Plant processes and distributes 600 to 800 thousand gallons daily.
Recent heavy rains from Tropical Storm Phillipe and Hurricane Tammy increased catchment water levels.
Antigua operates eight reverse osmosis plants, with Crabbs, Shell Beach, and Delaps being the highest producers.

The DataWORKS Reading Diagnostic Assessment (RDA) is designed to assess the current reading level of a student based on the five components of literacy:
The Reading Diagnostic Assessment is designed to pinpoint at what grade level students are reading based on their mastery of the content within each literacy component. A student entering a grade should ideally display reading skills typical of the low end of that grade. For example, a student entering first grade should know all of the letter names and sounds of those letters; whereas a student entering fifth grade should be able to read a fifth-grade passage fluently.
But, the reality is that many students are not reading at grade level, so the Reading Diagnostic Assessment allows teachers to pinpoint the areas where further instruction or remediation is required for each student.
See some samples of our Reading Diagnostic Assessments.
The Reading Diagnostic Assessment is available as an online assessment, or it can be downloaded and printed for hand-scoring.
Sample Online Assessment
Sample Printed Assessment
The assessment should be administered multiple times throughout the year. At the beginning of each school year, the assessment should be given to establish a baseline score for each student and to help teachers plan instruction or organize reading groups.
The assessment should then be repeated in the fall and spring to determine how much students have learned and what needs to be reviewed.
Finally, the assessment can be given a final time at the end of the school year to mark the highest level of literacy for that school year. The results from this end-of-year assessment can also be used in place of a baseline test at the beginning of the next school year, if needed.


"U" is the unit of weight. 2U stands for 90-94.9 grams, 3U stands for 85-89.9 grams, 4U stands for 80-84.9 grams, and 5U stands for 75-79.9 grams (all are unstrung weight).
VICTOR releases new grip indicator in 2013, provides consumers an easier way to select the racket that best suits their needs.
Tension, divided into lateral line H and vertical line V tension, is the safety factor of a racket frame, the maximum poundage that can be safety reached when a racket is strung. For example, H≤30lb V≤28lb means that, when a racket is strung, the highest lateral line tension is 30 lb and the highest vertical line tension is 28 lb.
The racket balance point is the distance from the front sleeve to the fulcrum, the higher the value the heavier the head is (HH), and the smaller the value the lighter the head (HL).
The stiffness of the shaft affects the feeling when you play badminton. When a soft racket (shaft) is used, the shuttlecock stays on the racket face for a longer time and is easier to control. Soft rackets are suited for use by beginners. When a stiff racket hits a shuttlecock, accuracy and efficiency of power delivery are better than with a soft racket; stiff rackets are best used only by advanced players.
The Response Indicator is classified into 10 levels which shows on the racket's shaft. The dot closes left side with stiff response, while right side with flexible response.

MTH RealTrax O-31 switch
Here are a few tips and tricks when working with MTH RealTrax:
 1. The two ground rails are not tied together. This is true for other track systems using non-metallic ties, including those from Atlas O and GarGraves. If you add a switch, you need to add a lockon and make sure it's on the opposite side of the track from the first lockon. This assures ground on both outside rails and prevents loss of ground through the switches. It also enhances the signal using a command system, and it gives a better chance that the ground power will be on all the track sections in case a copper connector was missed during assembly.
MTH RealTrax O-31 switch
MTH Illuminated Lock-On
 1. The larger the layout becomes, the more lockons are needed. Alternate the sides as you install them. MTH sells a separate ground track, which connects the two outside rails. If you can't find an MTH ground track, it's easy to make. Take any piece of track and solder a wire (under the track) from one copper contact to the other ground rail.
 1. If you're having trouble snapping the track together, put a small drop of plastic-compatible oil, such as Labelle no. 108, on the mating plastic connections.
 1. If you have an area where trains stop, remove the track in question and check that the copper contacts are still spot-welded to the rail. If they are, use a digital multimeter set to read resistance in ohms to check continuity. Disconnect the transformer, and then hold one probe on top of the rail while gently pressing down on the copper contact. It should show continuity. If it doesn't, the weld has broken and you should replace the track. Or see no. 5.
 1. Fortunately, a broken weld is easily fixed. Using a 1⁄16-inch bit, drill through the copper contact slightly into the rail where it was spot-welded. Using a soldering iron, fill the hole with solder.
 1. A "chattering" switch or a switch that throws by itself is usually caused by the non-derailing feature. Underneath are two ground rails that come together to form a V; they throw the points if a train approaches and they're set in the wrong direction. Once wheels have touched them, they ground and energize the switch rails to throw the points. Sometimes when the track hasn't been laid straight, it can cause these rails to touch. One way to solve this is to grind a small amount of metal from the end of the rail and insert a piece of plastic as an insulator. Attach the plastic to the rail with super glue, and sand to the same contour as the rail.
 1. If a train stops after going through a switch, the ground was probably lost. Place another lockon after the switch on the opposite side of the first lockon. Check track continuity before, through, and after the switch.
 1. If the points fail to close against the stock rail, turn the switch over and remove the bottom plate. You'll see two small, V-shaped springs with a round piece of plastic between them. Both legs of the spring should be on the same side of the post. If one has jumped over, carefully lift it to the correct side.

 1. Switch won't throw? When using track power, be sure the copper jumper under the first two screw terminals is making contact. If you're using auxiliary power, remove the jumper. Sometimes it's just a matter of reseating the switch motor. Watch the small magnets in the throw bars. They're sensitive to polarity, which can repel instead of grabbing the throw bar if in the wrong direction. Most often it's a problem with the controller. Take the controller apart and remove the light bulbs. Set your multimeter to ohms, and touch one probe to the black wire and the other to the red one. Move the handle and check for continuity. Then check the green wire and bend the copper contacts as needed.
 1. You can test switches on a workbench. Using wires with alligator clips, hook them to a power source. Clip the red, or hot, to a center rail. Take the ground, and touch each of the control rails for the non-derailing feature opposite from where the points are set. The switch points should throw to the correct position. Next, touch the ground to each of the two screws where the red and green wires would go from the controller. The switch should throw both ways.

NServiceBus creates a child container for each transport message that is received. During message processing, all InstancePerUnitOfWork scoped instances that are created are resolved as singletons within the context of the same message. This is helpful to support the sharing of database sessions and other resources with lifetimes specific to the processed message.
Objects can be configured in a child container scope using the InstancePerUnitOfWork lifetime:
 registration: components =>
Deterministic disposal
Child containers automatically dispose all IDisposable instances created with InstancePerUnitOfWork lifetime once the message is processed. This is useful for managing things like database sessions which must be disposed of properly.

How to Record Class Lectures with A Lecture Recorder
Download Screen Recorder For FREE！
As a teacher, you have to create innovative teaching methods time and again to avoid boring and tedious language so as to achieve better teaching quality. While as a student, heavy books and strain resulted from attending the class full of students and unwanted distraction may exhaust your spirits and led to poor absorption of knowledge. As a result, many students prefer written or video notes or online video lectures to improve their learning efficiency. Thus, is there any possible for teachers or lecturers to record lectures and upload them online for students? Of course! Here in this article, I would like to introduce you how to record class lectures with ease.
Ultimate Guidance - Record Class Lectures with VideoSolo Screen Recorder
Before we get started, you need to figure out that lectures can be divided into formal classroom lecture, private teaching and Webinar. The recording equipment will be different under different circumstances. Generally speaking, formal classroom lectures need specialized equipment to record, which is time-consuming and expensive. We are going to talk about how to record private teaching lecture and Webinar below.
To record lecture, you need to get a laptop with sufficient battery backup and a proper lecture recorder or screen recorder. Well, our highly recommendation is VideoSolo Screen Recorder, which can record and capture anything you want on the computer screen and even add a webcam footage. With this lecture capture software, you are able to:
- Record a detailed lecture with porfessional recording functions;
- Add voice comments or explain the lecture by turning on the audio recorder;
- Create a lecture with high-quality output for sharing online …
Step 1. Prepare Learning Materials
Firstly, get your lecture contents and slides prepared can help you maximize student engagement. Your learning materials may include a PowerPoint presentation, a video, images or web links in a browser etc.
Step 2. Launch the Program
Then, download and install VideoSolo Screen Recorder on your computer and launch the program. Then choose "Video Recorder" on the main interface to enter into the recording interface.
Step 3. Select Recording Area
Pull up all the learning materials on the computer screen and choose a suitable recording area. Turn on the webcam button and then you can see yourself on the screen. Now you need to make sure that you have a good light and neutral background. All your learning materials must be included in the recording area so that your students can understand what you are doing clearly.
The System Sound and Microphone buttons need to turn on at the same time, and you can adjust the volume to make your lecture presentation more clearly.
Step 4. Start Recording Your Lecture
Once other settings are done and the ambient environment is good, you can click "REC" to start recording. While recording, you can also annotate by adding shapes, letter and lines to emphasize your PowerPoint or images.
Step 5. Output the Lecture Recorded
Once you finished the recording, click the "Red square button" from the floating bar to stop the recording, then you can preview the video you just recorded. If you don't like it, click "Re-record" to record your lecture again; if it is good, click "Save" to output the video to your computer. Then you can share with your students or upload online.
From the above, teachers or other lecturers know how to record your teaching lectures to share with your students. If you are students and want to record what your teachers talking during the class, you can also use such screen recorder to record. However, you need to get permission from your teacher and should not break the law. Please follow the steps above to finish your recording.
That's how you can record lecture with lecture recorder. To sum it up, VideoSolo Screen Recorder to record lecture is great for individual creator. It is very important to create interesting and rich lecture in today's dynamic learning environment. With more and more flipped classroom and blended learning techniques appeared on schools and universities, efficient and high quality lecture capture is a huge part of that. If you want to record class lecture, why not download and have a try? Good luck!

How can mobile network operators optimise the network to give their subscribers the best performance for specific social media and data apps?
The best way to do so would be to understand how users are experiencing the application, and then understand what network optimisations will affect that QoE for the better.
But understanding the impact that the mobile network itself has on app QoE is not easy, as this large scale field trial investigating the performance of Facebook and Dropbox apps on the network found.
This report from Rohde & Schwarz explains the impact that various factors have on the final performance of an app. That includes the behaviour of the app itself, server availability and performance, as well as network parameters.
The report details:
– How the QoE of interactions with data smartphone apps can be measured
– The characteristics of a data transfer with a popular service like Facebook compared to a plain HTTP transfer to a self-hosted server
– How app tests should be used in mobile network testing campaigns
– The best process operators can take to optimise app performance

Calcium vapour deposition on semiconducting polymers studied by adsorption calorimetry and visible light absorption Hon, Sherman Siu-Man
A novel UHV microcalorimeter has been used to study the interaction between calcium and three polymers: MEH-PPV, MEH-PPP and P3HT. All three polymers behave differently in their reaction kinetics with calcium. On MEH-PPV we measure 45 μJ/cm² of heat generated in excess of the heat of bulk metal growth, 120 μJ/cm² for MEH-PPP, and 100 μJ/cm² for P3HT. Comparison of the MEH-PPV and MEHPPP data indicate that the initial reaction of calcium with MEH-PPV occurs at the vinylene group. We propose, based on hypothetical models, that calcium reacts with the vinylene groups of MEH-PPV with a reaction heat of 360 kJ/mol and at a projected surface density of 1.7 sites/nm², while it reacts with the phenylene groups of MEH-PPP in a two-step process with reaction heats of 200 and 360 kJ/mol respectively, at a projected surface density of 3.5 sites/nm². Optical absorption experiments, using either a 1.85 eV diode laser or a xenon lamp coupled to a scanning monochromator, have also been performed using the same calorimeter sensor. In the case of MEH-PPV, using the laser we find an optical absorption cross-section of 3E-¹⁷ cm² per incident calcium atom at low coverages. The change in absorptance at higher coverages correlates perfectly with the population of reacted Ca atoms determined calorimetrically. The size of the absorbance cross-section, and its position just within the band gap of the polymer, are consistent with the reaction being one of polaron formation. Calcium does not appear to dope P3HT, while the photon energy range of 1.5 to 3.75 eV used in these experiments is likely too small for probing polaronic energy states in MEH-PPP.

TODO after 1.10.
Implementation Notes
Changes from Current Behaviour
Rules Defined Only Once
The config-based parser would merge and override access entries in redefined rules. The new parser rejects authz files that define the same rule more than once.
New Rule Syntax for Wildcard Rules
Existing rules come in two flavours; repository-specific and global:
 [repos:/path]
 [/path]
In these rules, /path is always matched literally. The new parser supports two new forms for rules with paths that contain wildcards:
 [:glob:repos:/path]
 [:glob:/path]
Because a glob rule is not required to actually contain wildcards in the path, two sections with different names may represent the same rule; for example,
 [/path]
 [:glob:/path]
the above two rules are identical. The new parser detects (and rejects) such collisions.
Write-only Access is Not Allowed
The config-based authz parser will allow access entries that grant only write access; e.g.,
 [/]
 * = w
The new parser flags such entries as invalid; our authz implementation does not support write-only access.
Only Group Definitions in the Global Groups File
The new parser allows only group definitions (i.e., only the [groups] section) in the global groups file. The config-based parser would allow other sections there, but they would be ignored.
 - No labels

Question – Describe the causes for the tribal movements occurred during the British period. – 2 August 2021
Tribal movements were carried out on local issues, by local leadership and common people. These movements were mainly violent. These movements were sometimes against the British and sometimes against non-British such as money lenders, forest contractors etc.
Causes of tribal movements
- Forest laws: SuchForest laws were enacted by the British government that prevented tribals from living in protected areas. These forest laws also prohibited the use of products derived from forests. The British government established a forest department in 1864 to control the rich resources of Indian forests. The Government Forest Act, 1865 and the Indian Forest Act, 1868 established complete government monopoly on forest land.
- Land revenue system: The British government introducedstringent land revenue system. In addition to this, the traditions of joint ownership of land of tribals was deeply affected by extension of agriculture in the tribal areas or forest area by non-tribals and increased socio-economic discrimination in the egalitarian structure of tribal society.
- Exploitation: Beggar forced on the tribals by the forest contractors and external people and encroachment in tribal lands.
- Religious reform: Forced religious reform and conversion of tribal communities. The activities of Christian missionaries brought changes in the socio-economic and cultural equations of the tribals, they discouraging people to take up arms against the government. For this reason missionaries were seen as an extension of colonialism.
The area of influence of most tribal movements was limited, but these movements laid the foundation of future national movements.


What is Pretzel Salt?
Pretzel salt is a coarse large-grained white salt of uniform size with no additives. The grains are rectangular shaped and flat. This ensures that they adhere to pretzels and other baked goods like bagels, focaccia, bread or hard rolls. The salt can also be used in coarse rubs, for curing meat, for salt crusted fish, pickling and for zucchini fritters.
Pretzel salt is also described non-melting. (King Arthur)
A distinctive feature of Rock-Pretzel Salt is that it has a translucent appearance (Morton Salt)
Pretzel salt is also known as coarse food grade salt.
Common substitutes for pretzel salt include: bagel salt, kosher salt, Red Diamond sea salt, rock salt, and Coarse Mediterranean Sea Salt.
Where to buy it. you can buy it online at Amazon and other independent sellers. it can also be bought in supermarkets like Walmart.

Chatting With Astronauts
Students Connect With the International Space Station
NEW YORK, May 31, 2018 – Students at the Vaughn Next Century Learning Center, a member of the Center for Global Education's International Studies Schools Network, recently had the opportunity to interview two astronauts at the International Space Station.
Students from all of Vaughn's P–12 classes asked astronauts and former teachers Ricky Arnold and Scott Tingle questions on all sorts of topics, and a few even asked about cultural competence and global understanding!
You can watch the whole conversation below:

In early April, the Kids Fashion Weekend Spring Festival was held at the Zagreb Zoo, where children had the opportunity to participate in several exciting workshops and activities. The event was also supported by JGL in the form of an Aqua Maris corner, where children could take part in an educational workshop titled "Plant for cleaner air because breathing means life!".
In addition to planting and sowing seeds of plants well-known for their air-purifying qualities, children and their parents learned about the importance of plants for human health. They decorated their plant pots, which they could take home as an incentive to continue caring for their plants.
The little creative minds joined a workshop on making butterflies, picture frames and jewellery from repurposed materials. This reaffirmed the idea that not all waste should be thrown away and that it can be used creatively with the ultimate goal of preserving nature and the environment.
