merged tables. If no other tools are available, you can use diff(1) to collect differences between the /before and /after files, and merge manually with a text editor.
 The following example assumes that the merged results are available in /after.
 7. Load the merged data into NIS+. The following example uses the group table.
 # nisaddent -m -f /after/group group
 8. Remove LDAP entries that should not exist after the merge.
 A. If there are LDAP entries that do not exist in the (now merged) NIS+ data, and that should not exist in LDAP after the upload, you must remove those LDAP entries.
 Your LDAP server might provide a convenient method for removing multiple entries, such as a way to delete all entries in a container. If this is not the case, you can use ldapsearch(1) to generate a list of entries for each container. For example, to generate a list of all entries in the ou=Rpc container, use ldapsearch(1) as follows.
 # ldapsearch -h server-address -D bind-DN -w password \
 -b ou=Rpc,search-base 'objectClass=*' dn | \
 grep -i ou=Rpc | grep -v -i \^ou=Rpc > /tmp/delete-dn
 See Performance and Indexing for an explanation of the meta-arguments (server-address, bind-DN, for example).
 B. You can now edit the result file (/tmp/delete-dn) to specify only those entries that should be removed. Alternatively, in order to remove all entries in the container, use the file as is, and rely on the NIS+ upload to restore the LDAP data. Either way, you should backup the LDAP data before performing the ldapdelete operation below.
 C. Use ldapdelete to remove LDAP entries, redirecting stdout (which usually is one blank line for each entry removed) to /dev/null.
 # ldapdelete -h server-address -D bind-DN -w password \
 /tmp/delete-dn /dev/null
 D. Repeat the above procedure for each container that has at least one entry which must be removed.

How to capture Lazy Loading Images for Visual Regression Testing in Cypress
By Priyanka Bhat & Ganesh Hegde, Community Contributors -
Table of Contents
Website performance and speed it the key to customer engagement and retention. Developers use various methods to ensure that the website loading time is less. Lazy loading is one such strategy that loads web contents/resources only when needed, to increase the performance of web pages.
The web resources such as images, and files consume a lot of memory and decrease performance. Lazy loading is sometimes referred to as on-demand loading. This method ensures that the images load only when required, making the website faster.
One good example of lazy loading is _URL_ Once you navigated to the home page, you can scroll down, and the articles keep loading, this is a form of lazy loading with an infinity scroll.
Advantages of Lazy Loading
 - Improved User Experience: Lazy loading, ensure that it loads only part of the web page which is required. This reduces the load time of the web page and resource crunch which makes the web page glitch-free.
 - Less Resouce Utilization: This optimizes the resources so that website works seamlessly on lower configuration systems.
 - Improved Performance: As mentioned above it not only makes the user experience smoother but also makes the performance faster.
Disadvantages of Lazy Loading
 - Complicated Implementation: Lazy loading needs additional lines of code needs to be written so, this adds additional work to developers.
 - Search Engine Optimization: Lazy loading make impact adversely if indexing has not done properly. Hence, one should be very careful when implementing lazy loading.
 - Visual Testing: It is a testing technique, which compares two images pixel by pixel and provides the output that both are the same or different which can be used as pass/fail results for our tests. However, in case of Lazy Loading it might generate false results, since the images load on demand.
Difficulties with Lazy Loading in Visual Testing
As Visual Testing takes the screenshot of the web page and compares it with base images. Lazy loading makes the web resources load on demand, Images are also considered a resource so if you take a screenshot of the web page after navigating, you might not get the complete webpage. So, you need to work on a special testing mechanism for Visual Regression in Lazy Loading.
For example, when testing web page _URL_ when you navigate to this webpage only a few images will be loaded as you scroll the images keeps on loading. This is an example of lazy loading.
How to capture Lazy Loading Images for Visual Regression Testing in Cypress
Cypress is a Test Automation tool built with NodeJS. It can be used for different types of testing, such as API Testing, End to End testing, Unit Testing, Integration Testing, and Component Testing.
Cypress supports Visual Regression Testing. The Cypress Visual Regression Testing article explains the basic setup. This article explores how to set up a Cypress Visual Regression Test for Lazy loading web pages.
Usually, Lazy Loading website loads assets as you scroll, so when you perform Visual Regression tests you need to scroll down the page to the bottom. This action can be done using the cypress command
cy.scrollTo('bottom');
The above command scrolls the page to the bottom so all resources will be loaded, and then you can take a screenshot.
Run Cypress Tests on Real Device Cloud
The complete test script look like the below.
// visual-test.js
describe('Cypress Visual Testing Lazy Loading', () => {
it('Lazy Loading Test', () => {
cy.visit("_URL_
cy.scrollTo('bottom');
cy.compareSnapshot('lazy-loading');
})
})
Once you execute the test with the Cypress command
npx cypress run
The tests get executed, and the first run will be considered as the base run, Cypress captures the base image, and the subsequent run will compare with the base image and provide the result.
The report shows if there is any difference, highlighting the differences as seen below
Cypress Visual Test Result with Difference
If there is no difference Cypress simply mark the test result as Pass
Cypress Visual Test Result With No Difference
Visual Testing with Lazy Loading Web Pages using Percy and Cypress
BrowserStack's Percy is a cloud-based Visual Comparision tool, it provides a dedicated dashboard to compare the screenshots. Percy helps to review the images on the dashboard. The Percy provides cypress integration.
Cypress Visual Testing guide explains the integration of Cypress with Percy. Let's discuss how to implement Cypress Percy for lazy loading websites.
Step 1 Install @percy/cypress and @percy/cli
npm install --save-dev @percy/cli @percy/cypress
Step 2 Import @percy/cypress
Add the import statement inside cypress/support/index.js
//inside cypress/support/index.js
import '@percy/cypress';
Step 3 Create your lazy loading Visual Tests with Cypress and Percy
// visual-test.js
describe('Cypress Visual Testing Lazy Loading', () => {
it('Lazy Loading Test', () => {
cy.visit("_URL_
cy.scrollTo('bottom');
cy.percySnapshot('lazy-loading');
})
})
Step 4 Sign into Percy and create a Project. To do so Copy the Percy Token from Project Settings
Step 5 Enter the Percy Token using the following command for
 - macOS
export PERCY_TOKEN=<your_token>
 - Windows OS Command Line
set PERCY_TOKEN=<your_token>
 - PowerShell
$env:PERCY_TOKEN ="<your_token>"
Run your Percy Test
Execute your Percy Test using the command
npx percy exec -- cypress run
Once execution is completed, Navigate to Percy Dashboard and Check for the latest build
Lazy Loading Cypress Visual Test Result with Difference
If there is a change Percy will show the difference side by side
Lazy Loading Cypress Visual Test Result with No Difference
If there are no changes then Percy shows the message no Changes
Visual Testing is a smart and easy way for testing website UI functionality, However, with the modern architecture and design of web pages, Visual Testing has, its challenges. Lazy loading is one such challenge, at some extent the lazy loading website can be tested. However, if the website has implemented infinity scrolling then it would be difficult to test such a website with Visual testing.
For more accurate results, it is always recommended to use a Visual Testing tool like Percy that allows users to test on real devices and browser. Moreover, it uses pixel by pixel comparison to ensure that the visual regression is accurate and supports all the popular test automation frameworks such as Cypress, Playwright, Puppeteer, Storybook, TestCafe, etc.

Lost or Damaged Instructional Material Liability
Information from California Education Code (EC) regarding damage to student-issued instructional materials.
EC Section 60010 (h) defines instructional materials:
"Instructional materials" means all materials that are designed for use by pupils and their teachers as a learning resource and help pupils to acquire facts, skills, or opinions or to develop cognitive processes. Instructional materials may be printed or nonprinted, and may include textbooks, technology-based materials, other educational materials, and tests.
EC Section 60119(c)(1) defines sufficient textbooks or instructional materials as follows:
each pupil, including English learners, has a standards-aligned textbook or instructional materials, or both, to use in class and to take home.
EC Section 48904(a)(1) holds parents or guardians responsible for the cost of replacing a textbook that is willfully defaced or not returned:
…the parent or guardian of any minor…who willfully cuts, defaces, or otherwise injures in any way any property, real or personal, belonging to a school district or private school, or personal property of any school employee, shall be liable for all damages so caused by the minor. The liability of the parent or guardian shall not exceed ten thousand dollars ($10,000). The parent or guardian shall also be liable for the amount of any reward not exceeding ten thousand dollars ($10,000) paid pursuant to Section 53069.5 of the Government Code. The parent or guardian of a minor shall be liable to a school district or private school for all property belonging to the school district or private school loaned to the minor and not returned upon demand of an employee of the district or private school authorized to make the demand.
Thus wear or damage to instructional materials through ordinary use, or from manufacturing defect, would not apply.
EC Section 48904 (b)(1) allows schools to withhold student grades, diploma and transcripts:
Any school district or private school whose real or personal property has been willfully cut, defaced, or otherwise injured, or whose property is loaned to a pupil and willfully not returned upon demand of an employee of the district or private school authorized to make the demand may, after affording the pupil his or her due process rights, withhold the grades, diploma, and transcripts of the pupil responsible for the damage until the pupil or the pupil's parent or guardian has paid for the damages thereto…
EC Section 48904 (b)(2) provides the process:
The school district or private school shall notify the parent or guardian of the pupil in writing of the pupil's alleged misconduct before withholding the pupil's grades, diploma, or transcripts pursuant to this subdivision. When the minor and parent are unable to pay for the damages, or to return the property, the school district or private school shall provide a program of voluntary work for the minor in lieu of the payment of monetary damages. Upon completion of the voluntary work, the grades, diploma, and transcripts of the pupil shall be released.
EC Section 48904(b)(3) requires school districts to establish local policy:
The governing board of each school district or governing body of each private school shall establish rules and regulations governing procedures for the implementation of this subdivision…
In regards to a district specific policy, it's important to remember that a student must have access to textbooks both in the classroom and at home, thus withholding textbooks from a student or restricting textbook use to the library would be problematic. Also, please note the requirements of EC 48904(b)(2) requiring parent notification and the necessary opportunity for the student to be able to "work off" the cost of the instructional materials.
Please also be aware of EC Section 60070 which states:
No school official shall require any pupil, except pupils in classes for adults to purchase any instructional material for the pupils' use in the school.

Faddeev–Popov ghost
From Wikipedia, the free encyclopedia
Jump to: navigation, search
In physics, Faddeev–Popov ghosts (also called ghost fields) are additional fields which are introduced into gauge quantum field theories to maintain the consistency of the path integral formulation. They are named after Ludvig Faddeev and Victor Popov.[1]
There is also a more general meaning of the word "ghost" in theoretical physics, which is discussed below (see general ghosts in theoretical physics).
Overcounting in Feynman path integrals[edit]
The necessity for Faddeev–Popov ghosts follows from the requirement that in the path integral formulation, quantum field theories should yield unambiguous, non-singular solutions. This is not possible when a gauge symmetry is present since there is no procedure for selecting any one solution from a range of physically equivalent solutions, all related by a gauge transformation. The problem stems from the path integrals overcounting field configurations related by gauge symmetries, since those correspond to the same physical state; the measure of the path integrals contains a factor which does not allow obtaining various results directly from the original action using the regular methods (e.g., Feynman diagrams). It is possible, however, to modify the action, such that the regular methods will be applicable by adding some additional fields, which break the gauge symmetry, which are called the ghost fields. This technique is called the "Faddeev–Popov procedure" (see also BRST quantization). The ghost fields are a computational tool in that they do not correspond to any real particles in external states: they only appear as virtual particles in Feynman diagrams – or as the absence of some gauge configurations. However they are necessary to preserve unitarity.
The exact form or formulation of ghosts is dependent on the particular gauge chosen, although the same physical results are obtained with all the gauges. The Feynman-'t Hooft gauge is usually the simplest gauge for this purpose, and is assumed for the rest of this article.
Spin-statistics relation violated[edit]
The Faddeev–Popov ghosts violate the spin-statistics relation, which is another reason why they are often regarded as "non-physical" particles.
For example, in Yang–Mills theories (such as quantum chromodynamics) the ghosts are complex scalar fields (spin 0), but they anti-commute (like fermions).
In general, anti-commuting ghosts are associated with fermionic symmetries, while commuting ghosts are associated with bosonic symmetries.
Gauge fields and associated ghost fields[edit]
Appearance in Feynman diagrams[edit]
In Feynman diagrams the ghosts appear as closed loops wholly composed of 3-vertices, attached to the rest of the diagram via a gauge particle at each 3-vertex. Their contribution to the S-matrix is exactly cancelled (in the Feynman-'t Hooft gauge) by a contribution from a similar loop of gauge particles with only 3-vertex couplings or gauge attachments to the rest of the diagram. (A loop of gauge particles not wholly composed of 3-vertex couplings is not cancelled by ghosts.) The opposite sign of the contribution of the ghost and gauge loops is due to them having opposite fermionic/bosonic natures. (Closed fermion loops have an extra −1 associated with them; bosonic loops don't.)
Ghost field Lagrangian[edit]
The Lagrangian for the ghost fields c^a(x)\, in Yang–Mills theories (where a is an index in the adjoint representation of the gauge group) is given by
\mathcal{L}_\mathrm{ghost} = \partial_\mu \overline{c}^a\partial^\mu c^a + g f^{abc}(\partial^\mu\overline{c}^a) A_\mu^b c^c.
The first term is a kinetic term like for regular complex scalar fields, and the second term describes the interaction with the gauge fields. Note that in abelian gauge theories (such as quantum electrodynamics) the ghosts do not have any effect since f^{abc} = 0 and, consequently, the ghost particles do not interact with the gauge fields.
General ghosts in theoretical physics[edit]
The Faddeev–Popov ghosts are sometimes referred to as "good ghosts". The "bad ghosts" represent another, more general meaning of the word "ghost" in theoretical physics: states of negative norm—or fields with the wrong sign of the kinetic term, such as Pauli–Villars ghosts—whose existence allows the probabilities to be negative thus violating unitarity.
Changing the symmetry[edit]
Ghost particles could obtain the symmetry or break it in gauge fields. The "good ghost" particles actually obtain the symmetry by unchanging the "gauge fixing lagrangian" in a gauge transformation, while bad ghost particles break the symmetry by bringing in the non-abelian G-matrix which does change the symmetry, and this was the main reason to introduce the Gauge covariant and contravariant derivatives.

Since Foo has an Inner struct, though, we'll need to also provide a definition for this struct if we want to access the val value:
...
#define sandbox_fields_reflection_mylib_class_Inner(f, g, ...) \

Each struct file is intended to hold all struct definitions associated with a library.
Danger
The compiler currently doesn't catch type mismatches, missing members, or incorrectly ordered members in the struct definition.
Take a look at the ogg struct layout in Firefox for a complete example.
In the future we will likely generate these kinds of files automatically.
3.2 Invoking varargs functions
RLBox does not (yet) support calling functions with variable arguments currently. So, if the library you are sandboxing has APIs with variable arguments you need to monomorphize the usages. Specifically, you need to create wrapper functions for each usage you wish to expose. Consider the following example:
// Original library function:
int example_call(int x, int y, ...);
...
// Original invocations in application code:
rv = example_call(x, y, RESET_FLAG);
rv = example_call(x, y, INVERT_FLAG, 'c');
One way to handle this in RLBox is to expose two functions as follows:
int example_call_reset(int x, int y, uint8_t flag) {
 return example_call(x, y, flag);
}
int example_call_invert(int x, int y, uint8_t flag, char c) {
 return example_call(x, y, flag, c);
}
Then, you can call them as usual:
rv = sandbox.invoke_sandbox_function(example_call_reset, x, y, RESET_FLAG);
rv = sandbox.invoke_sandbox_function(example_call_invert, x, y, INVERT_FLAG, 'c');
3.3 Invoking C++ functions in a sandbox
RLBox does not currently let you invoke C++ library functions directly. Instead you need to expose a C ABI. Functions are largely straightforward. Methods require a bit of work since the receiver object is implicit: The simplest way to do this for class methods is to expose C functions and just pass a pointer to the receiver object as the first argument.
3.4 Passing application pointers into the sandbox with app_pointer
It's sometimes useful to pass application pointers into the sandbox. For example, you may need to pass a pointer to the receiver (this) so sandbox library can pass this pointer back in a callback. We can't trust the sandbox with actual applications pointers. RLBox instead provides a level of indirection.
If you want to pass a pointer into the sandbox you can use the get_app_pointer() <get_app_pointer> API, which returns an app_pointer. For example, in the expat library we need to pass a pointer to the receiver:
mAppPtr = mSandbox->get_app_pointer(static_cast<void*>(this));
// convert the app_pointer to tainted
tainted_expat<void*> t_driver = mAppPtr.to_tainted();
// call function as usual:
mSandbox->invoke_sandbox_function(..., t_driver);
where mAppPtr is a member of the class:
app_pointer_expat<void*> mAppPtr;
Internally, RLBox keeps a map between app pointers and the corresponding tainted pointers exposed to the sandbox. This lets you lookup the pointers in callbacks, for example:
void callback(rlbox_sandbox_expat& aSandbox, ... tainted_expat<void*> t_driver) {
 nsExpatDriver* self = aSandbox.lookup_app_ptr(rlbox::sandboxstatic_cast<nsExpatDriver*>(t_driver));
Like callbacks, you need to keep app pointers alive and unregister them when you're done:
mAppPtr.unregister();
4 Additional material
Here is some additional material on how to use RLBox.
 - A good next step after this tutorial is to get hands-on migrating an application to using a library that you want to sandbox. The simple library example repo is a "toy" application that uses a potentially "buggy" library. Try migrating the application to use the RLBox API based on what you've learnt in this tutorial. The solution is available in the solution folder in the same repo.
 - Here is an alternate short tutorial on using the RLBox APIs. Note that this tutorial uses an alternate RLBox sandbox plugin (which uses the Lucet Wasm compiler and RLBox plugin rather than the wasm2c based plugin recommended in this tutorial, but this does not affect the use of the RLBox APIs themselves).
 - Another useful example of using the RLBox APIs is the RLBox test suite itself.
 - You can also see usage of the RLBox APIs in the Firefox browser by using the Firefox code search.
 - Finally, the academic paper discussing the development of RLBox and its use in Firefox [RLBoxPaper] at the USENIX Security conference 2020 and the accompanying video explanations are a good way to get an overview of RLBox.

Development and Application of Grain Distillers Dried Yeast for Pacific White Shrimp Litopenaeus vannamei
Type of Degreethesis
Fisheries and Allied Aquacultures
MetadataShow full item record
In recent years there has been an increasing interest in developing low-cost feeds for the Pacific white shrimp, Litopenaeus vannamei. High prices and limited supply are the main factors that have affected primarily feed manufacturing companies. Therefore, animal and plant-based proteins have been evaluated as protein sources in order to reduce commercial shrimp feed costs. Facing this scenario, the idea of replacing fish meal with alternative protein sources, has reduced the dependence on marine ingredients commonly utilized in shrimp formulations. Fish meal has been used in shrimp diets as an excellent protein source due to its high level of nutrients as well as palatability. Nevertheless, the supply of fish meal have become very limited and most importantly, fluctuations in the price has stimulated alternative feed ingredients to be considered. Generally, animal proteins are more expensive than plant ingredients resulting in a considerable interest to evaluate plant by-products as protein sources. Shrimp formulations have included soybean meal, an acceptable protein ingredient with suitable digestibility and steady supply. However, soy products have a lower nutrient content compared to fish meal with regards to protein, essential amino acids, fatty acids, and minerals. Toward this goal, grain distillers dried yeast (GDDY), a co-product obtained from the bioethanol industry, has been evaluated in sunshine bass and rainbow trout with positive results. Therefore, a series of growth trials were conducted to evaluate the substitution of soybean meal with GDDY in clear and green water systems as well as pond conditions for shrimp culture. Results from these studies suggest that formulated diets containing increasing percentages of GDDY (20, and 30% of diet) with or without lysine supplementation can be utilized as a protein source. Positive results were demonstrated using GDDY up to 30% of diet without affecting growth, feed conversion ratio, and survival in clear water tanks. Consequently, GDDY was assessed up to 15% of diet in green water tanks as well as production ponds. Feed response was acceptable for all commercial shrimp feeds and production parameters were at suitable levels. There were no significant differences between any of the GDDY dietary treatments in either ponds or tank growth trials. Overall, results from these studies reveal that GDDY can be utilized as a promising protein source in combination with soybean meal in formulated diets for Pacific white shrimp, as long as dietary nutrients are well-balanced to meet their requirements. In conclusion, diets formulated with GDDY (up to 30% of diet) as the main protein source, did not impair shrimp performance. Furthermore, utilizing GDDY in commercial feeds might reduce feed costs and most importantly, promotes optimum growth.

'Method is quite similar to how your own ears work,' scientists say
Scientists have developed wireless earbuds that use AI for background noise cancellation in real time, an advance that may find a range of applications, including in smart-home speakers and tracking robots.
The earbuds, named "ClearBuds", were described in a presentation at the Association for Computing Machinery (ACM) International Conference on Mobile Systems, Applications, and Services last month.
Researchers from the University of Washington in the US used a novel microphone system and one of the first AI systems of the kind to operate in real-time and run on a smartphone to enhance the speaker's voice and reduce background noise.
"ClearBuds differentiate themselves from other wireless earbuds in two key ways," study co-lead author Maruchi Kim, a doctoral student in the Paul G Allen School of Computer Science & Engineering, said.
First, he explained that the novel earbuds use a dual microphone array – one in which each earbud creates two synchronised audio streams that provide information and allow spatial separation of sounds coming from different directions with higher resolution.
Second, researchers say the lightweight AI system further enhances the speaker's voice.
Although most commercial earbuds have microphones on each earbud, they say only one of them is actively sending audio to a phone at a time.
On the other hand, in ClearBuds, scientists say, each earbud sends a stream of audio to the phone.
Researchers developed bluetooth networking protocols for the earbuds to allow the two streams to be synchronised within 70 microseconds of each other.
The scientists' AI algorithm runs on the phone to process the audio streams.
They say it suppresses any non-voice sounds, and then isolates and enhances the speaker's voice that's coming in at the same time from both earbuds.
"Because the speaker's voice is close by and approximately equidistant from the two earbuds, the neural network can be trained to focus on just their speech and eliminate background sounds, including other voices," Ishan Chatterjee, a co-author of the study, said.
"This method is quite similar to how your own ears work. They use the time difference between sounds coming to your left and right ears to determine from which direction a sound came from," Mr Chatterjee explained.
Researchers also tested the earbuds by recording eight people reading from Project Gutenberg in noisy environments, such as a coffee shop or on a busy street.
In the test, scientists had 37 people rate 10- to 60-second clips of these recordings.
Clips processed through ClearBuds' AI were rated by participants as having the best noise suppression and the best overall listening experience, according to the study.
Citing one of the limitations of the earbuds, scientists said people would have to wear both the buds to get the noise suppression experience.
They say the real time communication system developed in the study could find other applications, including smart-home speakers, tracking robot locations, or search and rescue missions.

How to implement in-memory caching in ASP.NET Core
[ad_1]
Design patterns have evolved to address problems that are often encountered in software applications. They are solutions to recurring problems and complexities in software design. Design patterns fall into thrее distinct catеgoriеs: crеational, structural, and bеhavioral.
Crеational dеsign pattеrns arе usеd to abstract and simplify objеct crеation. Structural pattеrns arе usеd to define thе rеlationships among objects (e.g., inheritance and composition). And bеhavioral design patterns are used to control the ways objects interact with each other (e.g., collaboration and delegation).
Thе dеcorator dеsign pattеrn is a structural pattеrn that can bе usеd to attach functionality or bеhavior to an objеct dynamically or statically without altеring thе objеct's structurе. In this article, we'll use the decorator pattern to implement an in-memory cache in an ASP.NET Core application.
Note that ASP.NET Core does not have a cache object like its predecessor ASP.NET. However, it does offer various aching options including in-memory caching, distributed caching, and response caching. We can implement caching seamlessly in an ASP.NET Core application by leveraging the power of middleware or services alongside the decorator pattern.
To use the code examples provided in this article, you should have Visual Studio 2022 installed in your system. If you don't already have a copy, you can download Visual Studio 2022 here.
Create an ASP.NET Core Web API project in Visual Studio 2022
To create an ASP.NET Core 7 Web API project in Visual Studio 2022, follow the steps outlined below.
 1. Launch the Visual Studio 2022 IDE.
 2. Click on "Create new project."
 3. In the "Create new project" window, select "ASP.NET Core Web API" from the list of templates displayed.
 4. Click Next.
 5. In the "Configure your new project" window, specify the name and location for the new project.
 6. Optionally check the "Place solution and project in the same directory" check box, depending on your preferences.
 7. Click Next.
 8. In the "Additional Information" window shown next, leave the "Use controllers (uncheck to use minimal APIs)" box checked. We won't be using minimal APIs in this project.
 9. Elsewhere in the "Additional Information" window, leave the "Authentication Type" set to "None" (the default) and make sure the check boxes "Enable Open API Support," "Configure for HTTPS," and "Enable Docker" remain unchecked. We won't be using any of those features here.
 10. Click Create.
We'll use this ASP.NET Core Web API project to work with the code examples in the sections below.
What is a cached repository? Why do we need one?
Thе rеpository pattеrn is a widеly usеd dеsign pattеrn that hеlps sеparatе thе data accеss logic from thе rеst of an application. A cachеd rеpository is usеd to еnhancе thе еfficiеncy and pеrformancе of data accеss opеrations. It combinеs thе commonly usеd rеpository pattеrn with caching tеchniquеs.
Encapsulating opеrations likе quеrying, insеrting, updating, and dеlеting data in a rеpository class providеs a clеar abstraction layеr that allows thе application to intеract with thе undеrlying data storagе through thе rеpository. Adding caching functionality to the rеpository we can short-circuit rеpеtitivе, rеsourcе-intеnsivе data accеss opеrations and improve the performance our our application.
How a cached repository works
Hеrе is how a cachеd rеpository typically works:
 1. Thе cachеd rеpository first vеrifies if data requested by the client is storеd in the cachе.
 2. If thе data is not found in thе cachе, thе cachеd rеpository will pass thе rеquеst to thе undеrlying rеpository. Thе undеrlying rеpository will thеn fеtch thе data from its original sourcе, such as a databasе.
 3. Aftеr thе data is rеtriеvеd from thе data sourcе it is storеd in thе cachе.
 4. Finally, thе rеquеstеd data is rеturnеd to the client.
Using a caching mеchanism improvеs ovеrall pеrformancе and rеducеs thе load on thе data sourcе. Instеad of pеrforming thе еxpеnsivе opеration of rеtriеving data from the underlying data source again and again, subsеquеnt rеquеsts for thе samе data can bе sеrvеd from thе cachе.
You can implеmеnt cachеd rеpositoriеs using diffеrеnt caching mеchanisms such as in-mеmory caching, distributеd caching, or еvеn custom caching solutions. A cachеd rеpository can significantly еnhancе your application's pеrformancе by rеducing data accеss timе, reducing latеncy, and improving scalability.
By minimizing calls to thе original data sourcе, a cached repository improves application rеsponsivеnеss. Howеvеr, maintaining data consistеncy of the cache with thе actual data sourcе rеquirеs carеful considеration of cachе invalidation stratеgiеs.
Create a cache repository in ASP.NET Core
Before we create our cache repository, let's create a model class for our application. Right-click on our Web API project in the Solution Explorer window and create a new .cs file. Replace the default generated code with the following piece of code to create our model class.
 public class Author
 {
 public Guid Id { get; set; }
 public string FirstName { get; set; }
 public string LastName { get; set; }
 public string Address { get; set; }
 public string Phone { get; set; }
 public string City { get; set; }
 public string PostalCode { get; set; }
 public string Country { get; set; }
 }
Next, create an interface named IAuthorRepository that contains the declaration of the methods corresponding to the operations supported by our repository class. Replace the default generated code with the following code.
public interface IAuthorRepository
{
 Task<List<Author>> GetAuthorsAsync();
}
Now create a new class named AuthorRepository in a file having the same name with a .cs extension and enter the following code in there.
public class AuthorRepository: IAuthorRepository
 {
 private readonly List<Author> authorList;
 public AuthorRepository()
 {
 authorList = new List<Author>() {
 new Author()
 {
 Id = Guid.NewGuid(),
 FirstName = "Joydip",
 LastName = "Kanjilal",
 Address = "1 ABC Road",
 City = "Hyderabad",
 Country = "India",
 PostalCode = "500089",
 Phone = "_PHONE_"
 },
 new Author()
 {
 Id = Guid.NewGuid(),
 FirstName = "Steve",
 LastName = "Barnes",
 Address = "9/2A CT Road",
 City = "Chicago",
 Country = "USA",
 PostalCode = "101010",
 Phone = "_PHONE_"
 },
 new Author()
 {
 Id = Guid.NewGuid(),
 FirstName = "Michael",
 LastName = "Bogan",
 Address = "81 Red Road",
 City = "Sydney",
 Country = "Australia",
 PostalCode = "123456",
 Phone = "_PHONE_"
 }
 };
 }
 public async Task<List<Author>> GetAuthorsAsync()
 {
 return await Task.FromResult(authorList);
 }
 }

Spinal angiolipomas: MR features.
PURPOSE: To determine the MR features of spinal angiolipomas and to compare these findings with their histologic appearance. METHODS: The MR examinations of three patients with surgically proved angiolipomas were reviewed for tumor location and extent, signal characteristics, and pattern of contrast enhancement, and were then compared with the histologic findings. RESULTS: Four tumors were found in the three patients, all located in the posterior epidural compartment, averaging about 2.5 vertebral bodies in length. On noncontrast T1-weighted images, all lesions were inhomogeneous and hypointense relative to epidural fat. Inhomogeneous enhancement was seen in three lesions on postcontrast T1-weighted images obtained with fat-saturation techniques. Angiolipomas were least conspicuous on T2-weighted images. A high vascular content correlated with the presence of large hypointense regions on T1-weighted images. CONCLUSION: Spinal angiolipomas are typically hyperintense on noncontrast T-1-weighted images relative to other tumors. Angiolipomas that contain large hypointense foci on noncontrast T1-weighted images can be expected to have a high degree of vascularity.

Re: Counter - number of tags per intervalby LanX (Chancellor)
|on May 04, 2013 at 22:08 UTC||Need Help??|
Just another idea based on tuning your current algorithm which is quite clever! (Well after being understood - you know my opinion about clear naming ;-)
After analyzing the numbers you provided, I suppose that intersections of different ranges are comparatively rare and if they appear they stretch over long distances.
So it doesn't really make sense to go into the count loop for each individual point, just go on counting the "1" till you reach the next "boundary" and add them collectively to your counter instead incrementing them one by one with++.
The boundaries are nothing else as the sorted list of range starts-1 and stops. In your example for ID "b"
this means [9,11,15].
and results in the following flow
As you see, you can also stop counting between ranges and even try to jump forward in the file with seek.
3e6 Intervals/50 IDs *2 Borders = 120000 Borders
6e9 Points / ID
=> in average 6e9/12e4=50000 points between two adjacent borders, where you can avoid the whole count loop.
This should lead to a considerable boost!

We present a heuristic approach to solve a complex problem in production planning, the multistage lot-sizing problem with capacity constraints. It consists of determining the quantity to be produced in different periods in a planning horizon, such that an initially given demand forecast can be attained. We consider setup costs and setup times. Due the complexity to solve this problem, we developed methods based on evolutionary metaheuristics, more specifically a memetic algorithm. The proposed heuristics are evaluated using randomly generated instances and well-known examples in the literature.

Blood-clotting material mimics adhesive proteins of marine mussels
doi:10.1038/nindia.2020.189 Published online 27 December 2020
A biocompatible and biodegradable peptide-based hybrid material can help stop bleeding, a study reveals1. The material mimics the blood-clotting properties of fibrin and the adhesiveness of specific proteins found in the foot pad of marine mussels.
The material, when applied on rabbit wounds, has accelerated blood-clotting and wound healing with less blood loss than fibrin, a team of researchers has found.
The material, named as 'sealant', could potentially be used for treating traumatic injuries of accident victims and injured soldiers, the researchers say.
Scientists from the Indian Institute of Science Education and Research, and the West Bengal University of Animal and Fishery Sciences, both in Kolkata, India, synthesised a peptide-based sealant.
The researchers, led by Rituparna Sinha Roy and Samit Kumar Nandi, then tested the efficiency of the sealant in aiding blood clotting and closing wounds in rabbits without a suture.
They found that the sealant stopped bleeding from a rabbit liver wound within about 100 seconds. The sealant also closed full-thickness rabbit-skin wounds more efficiently than the fibrin, suture and stapler without causing any adverse immune reactions.
The sealant-treated wounds showed the growth of thick, matured and organised collagen bundles, suggesting that it is a better wound-healing agent than fibrin.
The sealant could prevent bacterial growth, indicating its potential to promote infection-free wound healing. Its clotting mechanism doesn't depend on the body's own blood-clotting process, making it potentially useful for treating patients with bleeding disorders such as haemophilia, the researchers say.

Starting up SACHIP v.0.21 NAME sachip v.0.21 -- a script to allow the user to create filtered spectra and light curves from XTE/SA data with either a single command-line entry, or a simplified Q/A session. USAGE sachip -[bcdghilmopt] DESCRIPTION SACHIP is a Perl script which allows the user to create and plot spectra and light curves for a given list of XTE Science Array files, taking into account (optional) time and energy filter information. All necessary information can be supplied by the user as switches on the command line, and the script can/will take sensible defaults in the absence of overriding user input. Alternatively, the script can be run interactively, in which case the user will be prompted for important parameters not supplied as switches. PARAMETERS (actually SWITCHES/FLAGS) (grouped by function): -i {file} - provide name of ASCII file containing list of XTE/SA files (assumed default: 'fits_files.txt'). -p {file} - provide root filename for product files - i.e.,'sachip -p paris' will create files, paris.pha. (assumed default:'sachip_out'). -b {number} - provide requested binning for light curve file - i.e.'sachip -b 1.0' will create 1-second bins. (assumed default: 32 seconds). -c "{channels}" - provide range of ORIGINAL (not binned) channel filters to be used in the accumulation, e.g. "10-20,40-100". -t "{times}" - provide range of times to be used to filter the data (additional to those already present in the GTI extension) when accumulating, e.g. "48798400.0-48798900.0". -m - Resultant spectra/curves will contain separate columns for each of the good data columns in the input files. -o - Resultant spectra/curves will contain the sum of all the good data columns (the default). -d - Take default values for all parameters not set on the command line. -g - Take all GOOD columns (this is not only the current default, but your only option at the moment). -s - Device to plot on (assumed default: '/xterm'). -l - Logfile switch. Currently, logging is the default (in a file sachip.log), and -l will disable this logging. -h - Print this help information. EXAMPLES sachip -b 8.0 -m -p torres -d will create and plot one spectra and one light curve file, The output files will be called and torres.pha, and will contain one column per input good data column. The light curve will have 8-sec binning. Sensible defaults taken for all other values. sachip -i kim.txt -t "{times}" -c "{channels}" -b 1000.0 -og will look in file 'kim.txt' for the list of input files, apply time and channel filter ranges as applied, and create and plot a 1000-sec binned light curve and a single spectrum, to be found in and sachip_out.pha. Values not provided will be prompted for (in this case, the root for the product file). sachip -d will take fits_files.txt and plot a spectrum and light curve for all the data with 32-sec resolution and put the data in and sachip_out.pha. sachip will prompt the user for each parameter. NOTES SACHIP is intended as a 'fast' tool to minimize the amount of FTOOLing around for the user with straightforward data analysis requirements. It is not intended to replace or reproduce the full functionality available from the individual FTOOLS. However, I'm open to suggestions about how to improve the script to meet commonly-occuring data analysis needs. Future versions will include calls to XTEFILT and MKTIME to apply simple data cleaning. BUGS Please report problems to SEE ALSO SAEXTRCT and FPLOT for more information.

A body-of-revolution finite-difference time-domain (BOR-FDTD) method was developed and employed to rigorously analyze axisymmetric transformation optics (TO) lenses. The novelty of the proposed BOR-FDTD technique is that analytical expressions were derived and presented to introduce obliquely incident plane waves into the total-field/ scattered-field formulation, allowing for accurate simulation of BOR objects in layered media illuminated by obliquely incident waves. The accuracy of the proposed method was verified by comparing numerical results with analytical solutions. The developed code was further utilized to study the imaging properties of a cylindrical TO Luneburg lens on a substrate, demonstrating the desired focusing of light onto a flat plane.

CASE STUDY: ACCESSIBLE EARTHQUAKES
Using research and color to solve accessibility problems for color blind and low vision users.
Earthquake Map, Original
Background
To ensure corporate risk insurance managers purchase the right amount of natural hazard coverage, my property insurance firm created detailed maps defining where disasters are more likely.
With earthquakes, bands of color were used to define zones where they are likely to happen within 50 to >500 year spans.
Challenge
During interviews, I learned color blind users were having trouble reading the maps. I recommended to the team that we revise the colors to make the maps more accessible.
Utilizing software that simulated color blindness, I presented the problem to my team. Using California to illustrate the problem, it was shown that as colors shift, it becomes difficult for color blind users to understand how the zones relate to each other, and several of the zones start to blend together. This lack of contrast between zones would also impact low vision users who have difficulty seeing subtle tonal variations.
Maps as viewed by users with Deuteranopia, Protanopia and Monochromacy color blindness.
Earthquake Map, Deuteranopia Earthquake Map, Protanopia Earthquake Map, Monochromacy
Earthquake Map, Adjusted
SOLUTION
Though it was important to keep colors close to their original versions to support legacy users, I created a revised palette, calibrating color hue and value, that would be more accessible.
Revising the colors became even more crucial as the resolution of the maps was improved mid-project, adding finer detail and demanding clear delineation between zones.
To further assure the maps could be easily read, I suggested the areas of least risk were left without color.
RESOLUTION
When evaluated using the simulation software, the revised maps performed much better. Subsequent user testing confirmed that the adjusted colors improved overall accessibility.
Revised colors as seen by people with Deuteranopia, Protanopia and Monochromacy.

IceBot
From RepRap
Jump to: navigation, search
PAGE UNDER CONSTRUCTION
The IceBot is a large scale 3D printer that is still in the development stages. Some parts and areas of the design change from day to day while others have remained the same since the initial phase of design.
The IceBot is set to have a printable area of 3'-0" cubed. Thats 3'-0" in in the XYZ directions. This printer is not being designed to move around much but to have a stationary spot in my shop.
Currently the printer will be using a Gantry system to move the extruder head on the XY axis. This design is similar to the Ultimaker. The Gantry design allows for fast and accurate printing due to low momentum and weight of the extruder head. The weight of the extruder is further reduced by the use of a Bowden extrusion system. The Bowden system allows for the motor pushing the plastic filament to be mounted to the frame as opposed to the printer head.
The Gantry system of the IceBot will use Torqspline Screws as opposed to the traditional belt method. This is due to the size of the printable area as well as the cost of belts large enough to accommodate movement along the axis'.
'''Z Axis'''
The Z Axis of the IceBot is the part that has changed the most both in design and concept. ABS and PLA plastics are both light weight and functional materials when used with smaller scale printers. The IceBot has the opportunity to do large prints of heavier materials such as Wax. Because of this the Z Axis has been redesigned many times in order to try to accomidate the possibility of 50 pound+ prints.
The current design uses 2 upright Acme screws placed at the center edge of the Z platform. In order to help stabalize the platform 4 smooth steel rods will be placed at each corner. These 4 rods will be removable in order to help remove objects from the printer.

UK researchers develop ultrasonic needle
A University of Glasgow-led project, which is developing this new type of surgical needle, is one of 15 engineering projects to share in 12.2 million pounds of funding from the Engineering and Physical Sciences Research Council (EPSRC).
Margaret Lucas, Professor of Ultrasonics at the University's School of Engineering, and her partner researchers at the Universities of Dundee and Edinburgh have received 982,000 pounds to support three years of work to develop a needle which vibrates at ultrasonic frequencies.
Previous ultrasonic cutting technology developed by Prof Lucas and her team is capable of removing the shell of an egg without damaging the membrane below.
The technology would allow doctors to penetrate bone with needles with much less force than is currently required, improving the effectiveness of biopsies and allowing a more effective delivery of drugs to parts of the body obscured by bone.
Ultrasonic needles could also make it easier for doctors to penetrate areas of hard tissue without affecting the surrounding soft tissue.
Previous research carried out by Professor Lucas has led to the development of ultrasonic cutting tools precise enough to remove sections from the shell of an egg without breaking the membrane underneath.
Professor Lucas said: "We've been working for several years to explore the applications of ultrasonic vibrations to allow surgeons to cut through bone more quickly and easily, and we're excited about the potential of applying

Proceedings of the XXVIII Congress of the International Society of Biomechanics in Sports
This study evaluated and compared the peak vertical ground reaction force (GRF) and rate of force development (RFD) for the eccentric and concentric phases of 4 lower body resistance training exercises, including the back squat, deadlift, step-up, and forward lunge. Sixteen women performed 2 repetitions of each of the 4 exercises at a 6 repetition maximum load. Kinetic data were acquired using a force platform. A repeated measures ANOVA was used to evaluate the differences in GRF between the exercises. Results revealed significant main effects for GRF both the eccentric (p ≤ 0.001) and concentric (p ≤ 0.001) phases. Significant main effects were also found for RFD for the eccentric (p ≤ 0.001) and concentric phases (p ≤ 0.001). Force and power requirements and osteogenic potential differ between these resistance training exercises.


text: We report on the interference that hydrogen sulfide can generate on the measurement of phosphorus in seawater with the Murphy & Riley method. Free sulfide can be found in a variety of saline systems, from partially closed fjords to eutrophic estuaries, river saline wedges, saline lagoons, etc. in concentrations ranging from 0.02 up to 10 mM and, thus, may be present in water samples without the analysts suspicion. We tested the effects of sulfide concentrations ranging from 0.005 up to 0.7 mM on the measurement of phosphorus concentrations from 10 mgP to 1.5 mgP-PO4 l-1. We characterized spectrophotometrically, the product and the dynamics of the interference and we provide a simple method to detect the interference "a posteriori" by computing the ratio between the absorbances at 350 and 690 nm. If sulfide has been measured in parallel, the absorbances, even those that have had high interference, can be corrected to values without the interference with the equations that we provide. We propose the routine use of this method whenever dealing with samples that could have some sulfide in solution.

Biomarkers study in rainbow trout exposed to industrially contaminated groundwater
AbstractThe spill of liquid industrial waste from chemical and petrochemical industries in Mercier lagoons located 20 km south of Montreal, Quebec, caused a major groundwater contamination by industrial contaminants. The aim of this study was to investigate the toxic effects of Mercier groundwater, following 4 and 14 days of exposure to graded concentrations from three wells at increasing distances 1.2, 2.7 and 5.4 km from the source of contamination. Rainbow trout were examined for several biomarkers of defense [ethoxyresorufin O-deethylase (EROD) and gluthatione S-transferase (GST) activities] and those of tissue damage [lipid peroxidation (LPO) and DNA strand breaks]. The results showed that EROD activity was significantly enhanced in hepatic tissue at 1.2 and 5.4 km, whereas inhibition in activity was observed in group at 2.7 km. Therefore, GST activity was significantly increased at 3.1% concentration for the 2.7 km well. No change in LPO was observed. However, a significant induction of DNA strand breaks in liver was obtained at each distance. In conclusion, the data suggest that the release of these contaminants in groundwater leads to increased biotransformation for coplanar aromatic hydrocarbons and DNA damage in groundwater.

Outdoor Activity Tracker
By transitioning their Mile-A-Day program to a mobile app, Come Alive Outside was able to automatically measure distance and use gamification concepts like points, streaks and badges to improve user adoption and program completion rates.
Programs the first year
User growth over the first year
Increase in reported participation the first year vs the previous year
Appivo built a comprehensive solution consisting of a mobile application for users and a web interface for program administration. Come Alive Outside is able to manage users and teams, launch programs with different goals, track usage and encourage users. Users of the mobile app are able to track their walks, view individual and team leader boards, unlock badges and send encouraging notes to each other.
The brainstorming process started by analyzing the original paper-based program and processes, taking into account rules and any required flexibility. While translating the program for the digital world, processes were optimized to improve the experience of both program administrators and participants.
The design process focused on simplicity and ease-of-use, as well as ensuring that the mobile app would be visually appealing and inline with Come Alive Outside's brand. Understanding the user types was key, as the app needed to resonate with children, adults, and adults entering data for their children. The iterative design process progressed from sketches to wireframes to full-color mockups.
The comprehensive design effort resulted in a strong roadmap for the development team to follow. The iterative development process started with the administrative web interface before moving on to the mobile app. The final development phase consisted of an internal test run and the completion of a few final tasks before launching to an initial group of participants.

Random positive definite matrix
How can I get a random positive definite (or positive semi definite) matrix of given order? I know that there is a inbuilt function random_matrix with an additional feature algorithm to set with it. But there we can get some special matrices like 'echelon_form', 'orthogonal' ', 'echelonizable', 'diagonalizable'.... but positive definite command is not in built there. Some other important matrix classes are not there. So how to obtain random matrix of those classes?

Description Usage Arguments Value Examples
Description
Once the preliminary work is done using "GA.prelim()", this function tests a specifc region/gene. Single SNP analyses are also incorporated.
Usage
1
2
GA.test(result.prelim,G,Gsub.id=NULL,bootstrap=NULL,
MinP.adjust=NULL,impute.method='fixed')
Arguments
result.prelim
The output of function "GEI.prelim()"
G
Genetic variants in the target region/gene, an m*q matrix where m is the subject ID and q is the total number of genetic variables. Note that the number of rows in Z should be same as the number of subjects.
Gsub.id
The subject id corresponding to the genotype matrix, an m dimensional vector. This is in order to match the phenotype and genotype matrix. The default is NULL, where the order is assumed to be matched with Y, X and time.
bootstrap
Whether to use bootstrap for small sample size adjustement. This is recommended when the number of subjects is small, or the set contains rare variants. The default is NULL, but a suggested number is 10000 when it is needed.
MinP.adjust
If the users would like to compare with the MinP test, this parameter specify the adjustment thereshold as in Gao, et al. (2008) "A multiple testing correction method for genetic association studies using correlated single nucleotide polymorphisms". Values from 0 to 1 are permitted. The default is NULL, i.e., no comparison. The value suggested by Gao, et al. (2008) is 0.95.
impute.method
Choose the imputation method when there is missing genotype. Can be "random", "fixed" or "bestguess". Given the estimated allele frequency, "random" simulates the genotype from binomial distribution; "fixed" uses the genotype expectation; "Best guess" uses the genotype with highest probability.

Here is how I do it on App Engine:
Step 1) Register an "app" on Facebook (cf. _URL_ ). You give Facebook a name for the app and a url. The url you register is the url to the page (jsp or servlet) that you want to handle the login. From the registration you get two strings, an "app ID" and an "app secret" (the latter being your password, do not give this out or write it in html).
For this example, let's say the url I register is "_URL_
2) From a webpage, say with a button, you redirect the user to the following url on Facebook, substituting your app id for "myfacebookappid" in the below example. You also have to choose which permissions (or "scopes") you want the ask the user (cf. _URL_ ). In the example I ask for access to the user's email only.
(A useful thing to know is that you can also pass along an optional string that will be returned unchanged in the "scope" parameter. For instance, I pass the user's datastore key, so I can retrieve the user when Facebook passes the key back to me. I do not do this in the example.)
Here is a jsp snippet:
<%_USER_ import="java.net.URLEncoder" %>
 String fbURL = "_URL_ + URLEncoder.encode("_URL_ + "&scope=email";
3) Your user will be forwarded to Facebook, and asked to approve the permissions you ask for. Then, the user will be redirected back to the url you have registered. In this example, this is "_URL_ which in my web.xml maps to the following servlet:
import org.json.JSONObject;
import org.json.JSONException;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class SignInFB extends HttpServlet {
 public void service(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
 String code = req.getParameter("code");
 if (code == null || code.equals("")) {
 // an error occurred, handle this
 String token = null;
 try {
 String g = "_URL_ + URLEncoder.encode("_URL_ "UTF-8") + "&client_secret=myfacebookappsecret&code=" + code;
 URL u = new URL(g);
 URLConnection c = u.openConnection();
 BufferedReader in = new BufferedReader(new InputStreamReader(c.getInputStream()));
 String inputLine;
 StringBuffer b = new StringBuffer();
 b.append(inputLine + "\n");
 token = b.toString();
 if (token.startsWith("{"))
 throw new Exception("error on requesting token: " + token + " with code: " + code);
 } catch (Exception e) {
 // an error occurred, handle this
 String graph = null;
 try {
 String g = "_URL_ + token;
 URL u = new URL(g);
 URLConnection c = u.openConnection();
 String inputLine;
 StringBuffer b = new StringBuffer();
 b.append(inputLine + "\n");
 graph = b.toString();
 } catch (Exception e) {
 // an error occurred, handle this
 String facebookId;
 String firstName;
 String middleNames;
 String lastName;
 String email;
 Gender gender;
 try {
 JSONObject json = new JSONObject(graph);
 facebookId = json.getString("id");
 firstName = json.getString("first_name");
 if (json.has("middle_name"))
 middleNames = json.getString("middle_name");
 middleNames = null;
 if (middleNames!= null && middleNames.equals(""))
 middleNames = null;
 lastName = json.getString("last_name");
 email = json.getString("email");
 if (json.has("gender")) {
 String g = json.getString("gender");
 if (g.equalsIgnoreCase("female"))
 gender = Gender.FEMALE;
 else if (g.equalsIgnoreCase("male"))
 gender = Gender.MALE;
 gender = Gender.UNKNOWN;
 } else {
 gender = Gender.UNKNOWN;
 } catch (JSONException e) {
 // an error occurred, handle this
I have removed error handling code, as you may want to handle it differently than I do. (Also, "Gender" is of course a class that I have defined.) At this point, you can use the data for whatever you want, like registering a new user or look for an existing user to log in. Note that the "myfacebookappsecret" string should of course be your app secret from Facebook.
You will need the "org.json" package to use this code, which you can find at: _URL_ (just take the.java files and add them to your code in an org/json folder structure).
I hope this helps. If anything is unclear, please do comment, and I will update the answer.
Ex animo, - Alexander.
I want to add a few tidbits of information, my apologies if some of this seems a bit excessive.
To be able to log in a user by his/her Facebook account, you need to know which user in the datastore we are talking about. If it's a new user, easy, create a new user object (with a field called "facebookId", or whatever you want to call it, whose value you get from Facebook), persist it in the datastore and log the user in.
If the user exist, you need to have the field with the facebookId. When the user is redirected from Facebook, you can grab the facebookId, and look in the datastore to find the user you want to log in.
If you already have users, you will need to let them log in the way you usually do, so you know who they are, then send them to Facebook, get the facebookId back and update their user object. This way, they can log in using Facebook the next time.
Another small note: The user will be presented with a screen on Facebook asking to allow your app access to whatever scopes you ask for, there is no way around this (the less scopes you ask for, the less intrusive it seems, though). However, this only happens the first time a user is redirected (unless you ask for more scopes later, then it'll ask again).

I don't see you validating the signed_request property to verify if the user/request is actually valid, but apart from that, those are indeed the steps to be taken... – Marcelo Mar 6 '12 at 11:01
Alexander, with this code, if the user was logged into facebook, and open my GAE, it will auto-check the facebook account? or the user will always need to click somewhere to "Authenticate"? – LeandroRezende Mar 6 '12 at 12:39
You can do two things with this code. (1) Allow new users to click "sign up with facebook" and (2) allow existing users to log in just by clicking a "log in with your facebook account". They can both click the same link, and when the servlet above is run, you can check the database and see if you have a registered user with this facebookId. If so, you can log that user in. If not, you can create a new user, and store the facebookId. Yes, if the user is logged into facebook and has approved any permissions, this code will log the person in, without having to click anywhere. – yngling Mar 6 '12 at 12:55
A small additional note: You can of course also allow existing users of your app to log in with Facebook (i.e. updating their user object with their facebookId). This can for instance be done by passing the user's datastore key in the state parameter I briefly mention, then letting the servlet above grab it and update the user with the facebookId (or you could use the session to detect the user instead). – yngling Mar 6 '12 at 13:35
Alexander, thx for all your ideas, tonight i will try to make it work on my APP – LeandroRezende Mar 6 '12 at 19:25
You can try face4j _URL_ We've used it on our product _URL_ and have open sourced it for anyone to use. It works well on GAE.
There is an example on the wiki which should help you integrate login with facebook in a few minutes.

When it comes to home décor, people are often drawn to unique and distinctive pieces that add character and charm to their space. One such item that has been gaining popularity in recent years is the church pew.
These timeless wooden benches have a rich history and bring with them an air of nostalgia and elegance. If you've ever wondered how to incorporate a church pew into your home, this article will guide you through the process of transforming this traditional seating into a stunning focal point for any room.
Church pews have long been considered staples of religious gatherings, providing comfort and support to worshipers throughout the years. However, their appeal extends far beyond the walls of churches. The craftsmanship and design details found in church pews can enhance any interior style, whether it be modern, rustic, or traditional. By introducing a church pew into your home, you not only bring a piece of history but also create a unique seating option that is both functional and visually striking.
The versatility of church pews allows you to place them in various areas of your home, from the entryway or hallway for a grand entrance statement to the dining room or living area for additional seating options. Regardless of where it is placed, decorating a church pew involves thoughtful consideration of its surroundings while honoring its historical significance.
In the following sections, we will explore step-by-step how to transform an ordinary church pew into an extraordinary addition to your home décor.
Choosing the Perfect Church Pew for Your Home
When it comes to decorating your home with a church pew, choosing the perfect one is essential. There are various styles and materials to consider, as well as factors to think about when selecting a church pew for your home. By taking these aspects into account, you can ensure that the church pew not only adds charm and character to your space but also fits seamlessly with your existing interior design.
When searching for a church pew, you'll come across different styles such as Victorian, Gothic, or Mission. Each style has its own unique characteristics and can make a distinct statement in your home. Additionally, you'll need to consider the material of the pew. Common options include wood, metal, or a combination of both. The choice of material will depend on the overall aesthetic of your home and your personal preferences.
In addition to style and material, there are several important factors to keep in mind when selecting a church pew for your home. First and foremost, consider the size of the space where you plan to place the pew. Measure the area carefully to ensure that the pew will fit comfortably without overcrowding the room.
It's also crucial to assess the condition of the pew before purchasing it. Look for any signs of damage or wear that may require restoration or repair.
|Mission||Combination (wood and metal)|
Ultimately, finding the perfect church pew for your home requires careful consideration of style, material, size, and condition. By taking the time to choose wisely, you can ensure that the church pew becomes a beloved and cherished addition to your home decor.
Preparing the Church Pew for Transformation
Before you begin decorating your church pew, it is important to assess the condition of the piece and make any necessary repairs or restorations. Here are some steps to help you prepare your church pew for its transformation:
- Assessing the Condition: Start by thoroughly examining the church pew for any damage, such as cracks, loose joints, or missing pieces. Make a note of any areas that require repair or restoration.
- Cleaning Techniques: Depending on the material of your church pew, there are different cleaning techniques to consider. For wooden pews, use a mild soap and water solution to gently clean the surface. Avoid using harsh chemicals that can damage the wood. For metal pews, wipe them down with a damp cloth and use a metal polish to remove any tarnish or rust.
- Restoring Techniques: If your church pew requires more extensive restoration work, such as repairing broken parts or refinishing the surface, you may want to consider hiring a professional furniture restorer who specializes in antique or vintage pieces. They can help bring back the original beauty of your church pew while ensuring its structural integrity.
Once you have completed these preparatory steps, you are ready to move on to transforming your church pew into a focal point of charm and character in your home decor.
Below is an ordered list of key steps in preparing your church pew for transformation:
- Assess the condition of the pew.
- Determine if any repairs or restorations are needed.
- Clean the pew using appropriate techniques based on its material.
- Consider professional restoration for more extensive repairs.
By taking these steps to properly prepare your church pew, you can ensure that it will be in optimal condition before moving on to the next stage of transforming it to fit into your home decor vision.
Working with the Existing Style of Your Home
When incorporating a church pew into your home decor, one important consideration is how to work with the existing style of your home. Whether your interior design theme is traditional, modern, or somewhere in between, there are ways to harmonize the church pew with your surroundings and create a cohesive look.
Harmonizing the church pew with your existing interior design theme
To ensure that the church pew seamlessly blends in with your home decor, it's essential to consider the overall style and aesthetic of your space. If you have a traditional or vintage-inspired interior, opt for a classic wooden church pew that complements the warm tones and finishes in the room. On the other hand, if your home has a more contemporary or minimalist design, choose a sleek and streamlined pew with clean lines.
To achieve harmony between the church pew and your existing furniture pieces, pay attention to details such as wood tone and shape. If you have predominantly dark wood furniture in your home, select a church pew with similar undertones. Similarly, if you have curved or ornate furnishings, look for a pew that features similar design elements.
Blending traditional and modern elements
Sometimes, it can be exciting to mix different styles within your home decor. By blending traditional and modern elements together with the church pew, you can create a unique and eclectic look. For instance, pair a rustic wooden pew with contemporary artwork or abstract sculptures for an intriguing contrast.
Another way to combine traditional and modern elements is by incorporating contrasting materials. If you have sleek metal accents in your space, consider choosing a church pew upholstered in luxurious velvet or textured fabric to add warmth and coziness.
Remember that achieving harmony between styles doesn't mean everything has to match perfectly. Instead, focus on creating visual interest through thoughtful juxtapositions that complement rather than clash with each other.
By working with the existing style of your home when decorating your church pew, you can seamlessly integrate this historical piece into your interior design. Whether you choose to harmonize the church pew with your existing theme or blend traditional and modern elements, the result will be a cohesive and visually appealing space that highlights the unique character of the pew.
Color and Finishing Touches
When it comes to decorating a church pew in your home, choosing the right colors and finishing touches can make all the difference in transforming its appearance. Here are some tips and ideas to help you bring out the beauty of your church pew.
1. Painting or Staining the Church Pew: One of the first decisions you will need to make is whether to paint or stain your church pew. Both options have their merits and it ultimately depends on the style you want to achieve.
If you're looking for a more rustic or vintage look, staining the wood can bring out its natural beauty. On the other hand, painting allows for more versatility when it comes to matching your home's color scheme or adding a pop of color as an accent piece.
2. Choosing the Right Upholstery or Cushions: Adding cushions or upholstery is not only a practical choice for comfort but also an opportunity to enhance the visual appeal of your church pew. When selecting fabrics, think about durability and how well they will coordinate with your existing décor. Neutral colors are always a safe choice, but don't be afraid to experiment with patterns or textures that reflect your personal style.
– TIP: Consider using removable cushion covers so that you can easily change them according to seasons or whenever you want a fresh new look.
3. Accessories and Decorative Accents: The finishing touches on your church pew can truly elevate its overall aesthetic. Think about incorporating decorative accents that reflect your personal taste and style. For example, if you want to emphasize its religious significance, consider placing religious icons or symbols on a small shelf attached to the back of the pew. Alternatively, you could display a collection of antique books or decorative objects that align with your interior design theme.
– TIP: You can also personalize your church pew by adding custom-made throw pillows or blankets that showcase your family name, monogram, or a meaningful quote.
By carefully choosing the colors and finishing touches for your church pew, you can create a stunning focal point in your home that seamlessly integrates with your existing décor. Whether you decide to paint or stain it, upholster it with luxurious fabrics, or showcase sentimental items on its surface, these details will help bring out the unique charm and character of your church pew.
Adding Personal Touches to Your Church Pew
Once you have chosen and prepared your church pew for transformation, it's time to add personal touches that will make it truly unique and reflective of your style. By incorporating sentimental items or family heirlooms, as well as displaying religious or decorative accents, you can create a meaningful and personalized space in your home.
One way to add a personal touch to your church pew is by including sentimental items or family heirlooms. These can be items that have been passed down through generations or hold special meaning to you and your family.
Consider placing small picture frames on the pew with

Evaluation-oriented software architecture modeling and user behavior analysis model
The University of Auckland
Wednesday 18 October 2006, 4-5 pm
School of IT Building, Lecture Theatre 123, Level 1
Software architecture design decides the quality of future product. How to choose suitable frameworks (such as middleware) and architectural styles is challenging. Our research shows that architecture modeling and automated architecture performance evaluation are essential and achievable at early stage of SDLC. MaramaMTE project (based on ArgoMTE project) is an environment for architects to model architecture designs, generate evaluation (mainly performance evaluation) test bed, and get evaluation results instantly. Architects can then choose the most suitable architecture for the next stage of software development life cycle. MaramaMTE project also supports user behavior analysis modeling, which generates complicated testing plan for load testing, currently, web load testing. The integration of MaramaMTE with complicated user behavior analysis model and other possible models makes MaramaMTE a comprehensive environment for software architecture modeling and evaluation.

|Abstract:||The stability of a thin conductive liquid film flowing along a solid wall is an important problem that occurs in many proposed fusion device designs. In this paper we investigate the linear stability of an electrically conductive liquid film of finite thickness in the presence of a strong magnetic field. Inviscid flows of finite and infinite electric conductivity are considered. The magnetic field is found to decrease the unstable growth rate for both finite and infinite conductivity fluids but only narrows the unstable modes for infinite conductivity fluids. Our theory serves as an extension to the classical theory by Chandrasekhar (1961) by considering the finite-thickness and finite-conductivity effects.|

Preparing the Land
In preparing the land, the Gather By team has to ensure that the seedlings are put in an environment where they can blossom to their full potential. Unfortunately, a huge threat to this is kikuyu grass, which is an invasive pest that interconnects underground and takes all the vital nutrients out of the plants around it. In order for these plants to blossom, the Gather By team has to implement necessary yet environmentally friendly measures to get rid of the kikuyu grass while ensuring minimal harm is caused to the leptospermum, surrounding plants, and to the bees. We found it beneficial to use organic pelargonic acid combined with the use of weed mats as you can see from the images below. The weed mats were put down early in the planting process with pelargonic acid to cut out light to start the first of bioregion plantings.
With the help of individuals, like Gavin Smith, we were able to connect with new people and we were able to bring in volunteers who shared our passion for bush regeneration and conservation. This was our first volunteering session, which has become an integral part of the Gather By model.
