During our regular "tech lunch," we have got our brains blown by the talk Lucas Cavalcanti & Edward Wible - Exploring four hidden superpowers of Datomic (slides) that summarizes the key benefits a startup bank in Brazil got from using this revolutionary database as the core of their technical backbone. We would like to share our highlights from the talk and a few other interesting resources.
What is Datomic?
Datomic is a transactional database (fully ACID) targeting the same audience as PostgreSQL and Oracle but with a radically different design and "interface," created by the same people as Clojure. It is append-only (i.e. no data overwrites), all data is stored in the simple yet very flexible and powerful form of entity-attribute-value-... tuples, queries run typically in the memory of the application and are written in Datalog, a declarative logic programming language. It may sound crazy but it actually makes great sense in the 21st century, contrary to the databases designed based on the constraints of 1970s.
Highlights from the talk
The 4 + 5 superpowers of Datomic are:
(1) Audit Trail - data is immutable, Datomic never forgets what was true at a point in time and fully integrates the concept of time. You can thus look at the database as of a certain time to discover the source of an error, the sequence of events, or to try new code with a particular past situation. Every "insertion" of a fact belongs to a transaction, which can be annotated with additional metadata such as who did it, why, and a correlation ID.
(2) Authorization - ensure that a customer only sees her data. You can define custom "rules" that can check facts about the data and use them as predicates to filter results, for example owns? that detects whether an entity is - directly or indirectly - owned by the requesting customer. Rules use the same query language and can recursively call themselves, making it possible to traverse the data tree - e.g. find all entities owned by a customer. Moreover, you can use Datomic's d/filter to return a "view" of the database that contains only the data that satisfies a rule, i.e. only the data owned by the customer.
(3) HTTP Caching - with Datomic it is trivial to find out when any (set of) data - f.ex. any data of a customer - has last changed and return 304 Not Modified if it hasn't changed since last, saving bandwidth.
(4) Mobile Sync - similarly you can use d/history and d/since to get the "diff" of the data between two dates and only send to the client the data that has changed.
(5) Future DB - you can easily "add" data locally to the database without "committing" them and pass this "future database" to your functions, for example to test a new piece of code that depends on the data.
(6) Testing - the d/with makes it easy to ensure a particular database state for a test without complicated set up and without any tear down. Moreover, a DB is just a collection of facts, so you can easily mock it in your code with normal data structures: (let [testdb [fact1, fact2, ..]] ..)
(7) Extend schema Every attribute in Datomic has a schema, defining its type (string, long, ..), cardinality, name, etc. But you can add your own attributes to the schema. The speakers have added :nubank/transform with values such as :pii, instructing their code that thus annotated attribute holds personally identifying information and needs to be encrypted at rest. (RDBMS databases certainlydon't let you extend their Data Definition Language to add new attributes to columns!)
(8) Sharding reads Note: Datomic doesn't do sharding so I am not sure what they spoked about. What you can do is create multiple "peers" - the servers that do the querying in their own memory - or (in Datomic Cloud) "query groups" for different user groups, such as production vs. analytics, so that heavy queries of one group do not affect the other ones. You can also split your database into multiple databases [not sure how that works] or partition your data for more efficient caching.
(9) DB aggregation When you have multiple databases - physical or "virtual" - it is trivial to query over all of them with a single query - just pass all of the databases as arguments to your query.
 - What Datomic brings to businesses by Val Waeselynck - explains the value of Datomic in business terms while also providing the technical background, mentions some drawbacks, and shares his company's experiences with it. Benefits: high query power => it's straightforward to translate a question about data to code, no data loss, straightforward and flexible data modeling, simplified testing, easy to reproduce the circumstances of a bug in your local environment, easy to detect "what changed" and send that to other systems, great performance characteristics for the most common use cases, some of the hardest problems with databases are gone (object-relational impedance mismatch, N+1 selects problem, cache invalidation, concurrency). Other highlights: From MongoDB and NodeJS to Datomic and Clojure: In 4 weeks, 13k lines of hacky, untested JavaScript code turned into 9k lines of well-tested Clojure code (plus 3k lines of tests). After migrating, our situation drastically improved, mostly because of the above-mentioned properties of Datomic (although Clojure's interactive development story also played a significant role in increasing productivity and quality): - the time we spend fixing bugs has gone down below 5% [from 30-50%], [..] Datomic enables us to write mostly system-level tests [... which] yield much more coverage
 - Talk Domain modeling with datalog by Norbert Wojtowicz - This talk introduces Datalog from its primitives and builds a mental model of how complicated queries can be resolved using simple data structures. This, in turn, will help you understand when and how you should apply Datalog in practice: on the client, on the server, as a graph database, as a communication protocol ala GraphQL/Falcor, or as an event-sourcing storage mechanism. A well done introduction to querying with Datalog and data modeling with entity-attribute-value on the example of GitHub, demonstrating the power and simplicity of Datalog. Mention of (possibly recursive) "rules" e.g. for graph traversal with upfront unknown distance, creating a "subset view of a DB" with filter, annotating transactions with additional metadata for troubleshooting. On the model - every new feature typically adds a new relation (playlist = user -> songs, ...) which leads in RDBMS to more joins and a performance nightmare while in Datalog/Datomic it is just new facts, i.e. more of the same. Explanation of how Datomic can be used as relational (table-based) / key-value / graph /... storage, having 4 indices to support all these traversals. Briefly about Pull API, i.e. "GraphQL on steroids".
 - Talk KotlinConf 2018 - Datomic: The Most Innovative DB You've Never Heard Of by August Lilleaas a really good talk that presents the "weird" things about Datomic (single write thread, client-side queries, weird transactions, 4 "covering indices") and how they actually make perfect sense, plus a demo of inserting, querying, and updating data and of "time travel". There is also blog post with ± the same content and two later (2018) interesting posts, Datomic: Look at all the things I'm not doing! and Datomic: Look at all the things I'm not doing! (Cont.)

Will I notice a meaningful reduction in my local mosquito population?
Many people have anecdotally reported reduced mosquitos. Another controlled study documented that bats could significantly reduce egg laying success for mosquitoes. Recently, a paper published in the Journal of Mammalogy reported a new study from Wisconsin that documented widespread consumption, by little brown and big brown bats, of 15 species of mosquitoes, nine of which are known carriers of West Nile virus. These two species are the most frequent bat house users in the northern half of the U.S. and Canada.

Introduction
If you've been working with ASP.NET MVC, then you are almost certainly familiar with Html.BeginForm(). Html.BeginForm() is an HTML helper that makes it easier to write an HTML form block in an MVC view.
Listing 1 shows how you would use this helper in a Razor view. The using statement is used to ensure that the form is closed at the end of the using block. (This is exactly the same using keyword that we can use in C# code to ensure objects are disposed once execution leaves the using block.) The resulting HTML is shown in Listing 2.
Listing 1: Using Html.BeginForm() to create an HTML form
@using (Html.BeginForm())
{
 <fieldset>
 @Html.LabelFor(m => m.EmailAddress)
 @Html.TextBoxFor(m => m.EmailAddress)
 @Html.ValidationMessageFor(m => m.EmailAddress)
 <input type="submit" value="Submit" />
 </fieldset>
}
Listing 2: The HTML produced from Listing 1
<form action="/" method="post">
 <fieldset>
 Email address
 <input data-val="true" data-val-required="The Email address field is required."
 id="EmailAddress" name="EmailAddress" type="text" value="" />

 <input type="submit" value="Submit" />
 </fieldset>
</form>
Note that, in the example above, the form is just posting back to the same action. Html.BeginForm() has a number of overloads that take additional arguments for doing things like posting to another action.
BeginForm() and AJAX
There are times when, in response to the user submitting a form, you don't want the entire page to refresh. For example, let's say you have a small form to send an email. When the user sends that email, you might want them to remain on the current page. Perhaps you'd like to simply pop up a message that says the email was sent, rather than refreshing the entire page or redirecting to another page. Depending on your application's workflow, this approach might provider a better user experience. And AJAX is the perfect solution for implementing this type of behavior.
You can use AJAX in combination with the HTML.BeginForm() helper. For example, you could write jQuery to handle $('form').submit() and simply write your own code to perform an AJAX post or any other custom tasks.
There's nothing about Html.BeginForm() that is incompatible with AJAX posts. However, if you are looking for syntax to perform an AJAX post that is as simple and easy as the syntax described above for performing regular posts, then you'll be interested in the Ajax.BeginForm() HTML helper.
Ajax.BeginForm()
Ajax.BeginForm() is designed to work very much like Html.BeginForm() except that Ajax.BeginForm(), as you might expect, performs an AJAX post.
Like Html.BeginForm(), Ajax.BeginForm() has a number of overloads that accept additional arguments. For example, you can specify the action and controller (just as you can with Html.BeginForm()). You can specify an element in your view that will automatically be updated with text that is returned from the action. You can also specify JavaScript functions that should be called in response to various events of the AJAX post.
Listing 3 shows some code that uses Ajax.BeginForm(). The code specifies an action in the current controller that the data will be posted to. It also specifies a JavaScript function to call after the AJAX post succeeds, and another function to call should the AJAX post fail.
My OnSuccess() function simply displays the string returned from the action. We could also return complex JSON objects if we needed additional information. My OnFailure() function just displays a general error message.
I should point out that, if there is an error in my action, it's up to me to handle that error and return an appropriate result. The OnSuccess() function will still be called. OnFailure() only gets called if there was an error during the process of calling or returning from the action.
Listing 3: Example using Ajax.BeginForm()
@using (Ajax.BeginForm("PerformAction",
 new AjaxOptions { OnSuccess = "OnSuccess", OnFailure = "OnFailure" }))
{
 <fieldset>
 @Html.LabelFor(m => m.EmailAddress)
 @Html.TextBoxFor(m => m.EmailAddress)
 @Html.ValidationMessageFor(m => m.EmailAddress)
 <input type="submit" value="Submit" />
 </fieldset>
}

The code above also demonstrates that client-side validation still works for forms created with Ajax.BeginForm(). Just make sure you include the appropriate JavaScript files.
A link to download my demo application is at the top of this article. It extends the code above into a small but fully functional project that illustrates this technique.
Conclusion
So, there you have my description of Ajax.BeginForm(), a convenience when implementing AJAX posts in your MVC views.
I should point out, however, that there are some who prefer not to use this helper. Some developers prefer using Html.BeginForm() and then writing jQuery to implement the AJAX post, a technique I described earlier in this article. These developers sometimes feel that writing their own jQuery gives them more control.
So it's probably a trade off between a convenience that requires less typing and an approach that gives you maximum control. As long as you understand the two approaches, you'll be in a good position to judge which one makes the most sense for you.

There is complete lack of information on roosting behavior of the house swift, Apus affinis native to Chhattisgarh. Therefore, we studied the roosting behavior (exit and entry patterns from/to its roosting site) of the house swift. Attempts were also made to ascertain the modulatory role of environmental factors. We monitored the exit and entry timings of the house swift in the roosting site located on the busiest commercial area of Raipur city, India, for eight consecutive days, every month over a period of two years. The exit and entry timings showed positive relationship with the sunrise and sunset, respectively. The house swift exited tater and entered earlier in winter as compared with summer and monsoon seasons. A significant negative correlation between exit time and morning ambient temperature, and positive correlation between entry time and evening temperature was witnessed. Unlike exit time, the entry time was negatively associated with the humidity. The emry time was also associated with light intensity. In summary, we conclude that various environmental factors, viz., sunrise time, sunset time, temperature, humidity and light intensity are likely to produce statistically significant effect on roosting behavior of the house swift. This study is, however, inadequate to answer the following questions: (1) how the first bird of the colony determines that it is the time to fly out? (2) Is it the same individual that flies out first daily? Nonetheless, the findings of the present study may have important bearings on the safety of civil and military flights.

fluid. High amounts of carbon indicate thermal degradation of the fluid and a probable coking/sludge problem on the heat exchanger/heater surfaces or fluid oxidation. Coke and sludge can adversely affect a system's heat transfer efficiency by heat transfer surface fouling. An insolubles level of 50mg solids /100ml fluids can sometimes indicate problems.
High and Low Boilers
High and low boilers are formed when heat transfer fluids are heated to a high temperature and certain molecular bonds begin to break or thermally degrade. Some of the new materials that form have a lower molecular weight and typically a lower boiling point than the original fluid: These are low boilers. Other compounds resulting from thermal degradation will polymerize into higher molecular weight and higher boiling point molecules than the original fluid: These are high boilers. High and low boilers seen in components may not have the heat transfer efficiency and thermal stability of the original heat transfer fluid molecules. This measure of the charge in chemical composition to determine the presence of high and low boilers can be determined by two tests performed for cross reference. The first is an atmospheric or vacuum distillation; the second is a simulated distillation using gas chromatography (GC). The atmospheric or vacuum distillation test accurately detects high boilers, and in this test, the fluid is completely distilled. By comparison, the GC completes the run at a specific final temperature. GC analysis is extremely accurate detecting low boilers, especially aromatics, up to the initial boiling temperature of the fluid.
This test measures certain fluid flow characteristics per unit time. It can be used as an indicator of thermal degradation since low boilers will tend to reduce viscosity while high boilers will increase it. Viscosity changes also affect the overall heat transfer capabilities of the fluid.
GC Scan
This test gives a signature of the components of heat transfer fluids, degradation products (highlow boilers) and often can detect contamination. This information is cross-referenced with the atmospheric boiling range test to confirm levels of high and low boilers as well as the presence or absence of outside contaminants.
Flashpoint (Cleveland Open Cup)
This test provides a means of determining the fire/flashpoint of a fluid. Low boilers created as a result of thermal degradation will lower of the flashpoint. Outside contaminants may have a similar effect. As such, a low flashpoint serves to indicated the presence of thermal degradation products/outside contaminants.
Putting the tests to use
Preventive maintenance analysis of heat transfer fluids can aid in maintaining high level heat transfer system performance at minimum cost through proper interpretation of the sample data. Some of the common tests serve as primary indicators of fluid condition while others serve to confirm these primary indicators. The primary tests are: Moisture [ASTM D1744 (Karl Fischer)] Percentage of high/low boilers (ASTM D86 or ASTM D1160 and ASTM D2887) Insolubles [ASTM 893 (Modifies)] Each of these tests defines a major area of fluid quality and system performance. The secondary tests – specific gravity, acid number, viscosity and flashpoint – then can be used to confirm the interpretations reached with the data generated by the primary tests. The moisture content, as defined by ASTM D1744 (Karl Fisher), generally is a primary indicator of the integrity of a water/fluid interface. Two examples of this interface would be water-cooled heat exchangers or reactor jackets in which water is a component of the product being processed. Although some moisture from humid air may be drawn into the fluid through improperly blanketed expansion tanks in liquid-phase systems or during the cooling phase of sample collection, moisture levels in excess of 500 ppm (0.05%) or the presence of free water in a sample generally indicate a failure at a water/fluid interface. Initially, such failures usually are not dramatic. Generally, the leak is of the "pinhole" variety, and in fact, depending on the type of fluid in use, system pressures may not be noticeably affected at the onset. Sample frequency should be increased to confirm and monitor the situation, and plans should be made to examine or repair the appropriate heat exchange surface at the next scheduled shutdown. Should moisture levels in subsequent samples increase, or the system begin to excessively pressurize, more immediate action may be required. High/low boiler content as defined by ASTM D86 or ASTM D1160 and ASTM D2887 serve as an indicator of heat transfer fluid thermal degradation or outside contamination. ASTM D86 and D1160 are initialand final-boiling point determination distillations. ASTM D1160, a vacuum distillation, is used when the boiling points are too elevated to make atmospheric distillation practical (d86) or the product being tested thermally degrades at its atmospheric boiling point/range. ASTM D2887 is a gas chromatography-simulated distillation, which also defines the initial and final boiling points of products being tested. In each case, once the initial and final boiling points of virgin products are known, used fluid may be tested to determine if high/low boilers are present. Heat transfer fluids gradually degrade during normal use with the rate of thermal degradation increasing as the fluid approaches the high end of its bulk fluid operating temperature. Experience indicates that under normal conditions, most fluids with 5% low boilers or 10% high boiler levels call for reprocessing or replacement to maintain heat transfer capabilities. In the case of a dramatic increase in high or low boiler levels from the previous sample, and with the fluid still operating within its maximum bulk operating temperatures, either outside contamination, heater malfunction or decreased fluid flow rate may be assumed to be the cause. The presence of other outside contaminants can be determined by an examination of the ASTM D2887 GC trace of the sample and a comparison of that with the virgin product trace. One caution: With petroleum-based fluids, the contaminant, depending on molecular weight, may sometimes be masked within the characteristic bell-shaped petroleum CG trace. However, the contaminant usually will thermally degrade, and its components may be seen as high or low boilers. In either case, the product being processed by the system should be the first candidate as the outside contaminant. If the identity of the contaminant is confirmed to be product under process, a leaking product/heat transfer fluid interface should be suspected. The solution is similar to that of high moisture: Increase sample frequency to monitor the situation while making provision for repair. In some cases, the nature of the contaminant or the size of the leak may require immediate action. A rapid increase in high/low boiler also may be indicative of heater malfunction. Either flame impingement on a tube and/or excessive tube carboning can cause abnormally high film temperatures, resulting in increased thermal degradation. A low fluid flow rate due to circulation pump wear or a restriction to flow in the system may contribute to the problem, especially in systems operating at maximum bulk fluid/film temperature. Again, increased sampling is warranted, the process pump flow rate and heater should be checked and provision made for heater tube wall examination during the next scheduled shutdown. Insolubles, as defined by ASTM D893 (modified) primarily measures pipe slag, metal fines, hard carbon and other inorganic contaminants. Insoluble solids measurements in excess of 50mg solids/100ml fluids, and especially in excess of 250mg solids/100ml fluids of particles above 10pm, call for installation of slip-stream filtration in the system where a modest pressure drop is available to filter a low flow slip stream (less than 1% of the main flow rate). This will minimize wear on mechanical components such as pumps and valves. The presence of metal fines may indicate process pump, mechanical seal, or valve wear. Pipe slag, bits of welding beads, sand, etc. are commonly found in new systems after systems after startup or in older systems that have not been filtered. The presence of hard carbon may confirm heater tube fouling, degraded process material for contamination and often, insoluble fluid oxidation products. Of note, the presence of hard carbon also may indicate heat exchange surface fouling that will decrease production capabilities. A simple ashing test or solvent-washing and vacuum-drying solids collected from the system will determine if the solids are inorganic (mill scale, sand, etc.) or organic (fluid oxidation products or carbon from over heating) in origin. High ash content indicates the solids are inorganic in nature while a low ash content indicates the origin of the solids was from an organic material. These changes in solids content may lead to heat exchange surface fouling and result in increases in production times of only a few seconds per day. However, over the course of years, a significant reduction of production capability may occur almost unnoticed. As a result, if excessive hard carbon is present, heat exchange surfaces should be checked periodically to determine if fouling and its resultant production loss is present. Preventive maintenance analysis of high temperature heat transfer fluids greatly reduces the unpredictability of heat transfer system performance. Proper interpretation of the data allows early identification of potential system problems. Planned maintenance based on the used fluid analysis reduces unscheduled system downtime caused by system upsets. In addition to these cost reductions, fluid costs are reduced since fluid changeouts or reprocessing can occur on a scheduled basis, maximizing fluid life and heat transfer capabilities.
Cost Effective Alternatives to Changing Thermal System Fluid
By Michael R. Damiani, Radco Industries Inc. During normal operation, heat transfer fluids can degrade due to thermal stress or oxidation. Fluids can also become contaminated through heat exchanger leaks. Often, degradation and contamination lead to a significant decrease in heat transfer fluid efficiency, increasing production time and costs. In many cases a full fluid change-out may be required to restore system performance, but many times these other cost-effective alternatives listed below can extend fluid life and maximize system performance: Fluid Reprocessing.

Before you start you will need an android tablet and a wireless router in the Lab.
I have a Samsung Galaxy Tab E and an Airport Express, but other tablets and routers should work as well.
To install knobby tablet follow the following steps:
- Download knobby tablet from the Google Play store.
- Download and install the latest version of Scanbox (as always keep a copy of previous version).
- Download and install PyOSC. To install, open a terminal, go to the directory where you uncompressed PyOSC, and type "python setup.py install".
- Copy over the settings in the scanbox_config.m file.
- Connect the computer running Scanbox to your local wireless router
- Open a terminal window and check the IP assigned to the computer by typing ifconfig.
- Set the tri_knob configuration variable in scanbox_config.m to a string that contains the IP address, for example, '184.108.40.206'.
- Start Scanbox. You should also get a command window with the knobby tablet console. We will check if commands from the tablet are received there.
- Open knobby tablet on your Android. You will likely get a message saying that the default IP is invalid. Click Ok.
- Click on the IP number button. A keyboard will show up. Enter the IP number you found above. However, make sure that every section has 3 digits (use zeros if necessary). Thus, in the example above, one would type 164.034.123.031
- If the tablet cannot connect, you will see an "Invalid IP" message. Otherwise, you should be ready to go. The IP gets stored in the tablet, so launching knobby tablet later will retrieve it.
- Remove the objective from the microscope (just in case).
- Make sure the scope is roughly in the middle of its travel for all axes.
- Click the "Normal" button on the tablet. Do you see a message printed on the knobby console? If so, communication is working Ok. If not, something is wrong. Contact me.
- Stand close to the motor box so you can quickly power it off if something does not work as expected.
- Now touch the button corresponding to the Z axis on the red region. The z-axis will begin to move so long as you keep touching it. The speed of movement will be faster the farther away you are from the center. Slide your finger left and right, the speed will change and it should reverse if you move over to the blue side.
- Test the other axes.
- Touch "Velocity" to switch to velocity mode.
- Warning: the microscope will move fast now… Touch the red or blue areas of each button. The microscope will move at a fast/fixed speed so long as you keep touching the area. It will stop when you release.
- Store/Recall buttons work as before
- Go back and try the Fine and Super-Fine modes.
- Play with it for a while and install the objective back after you familiarize yourself with the tablet interface and everything seems to be working Ok.
- You can minimize the knobby console once testing is done (I will do this automatically in future versions).
- The green buttons on the side lock the button area (bottom) or knob area (top). So if you are acquiring data and don't want to have a situation where people touch the tablet by mistake and move the microscope you can use the buttons to lock them. Touching them again will unlock.
- Make sure you open knobby on your tablet after you start Scanbox.
If you run into problems don't hesitate to write.

jsvutil
A Node.js utility wrapper for the JSON Schema Validator (JSV).
Overview
JSV is an excellent module by Gary Court. This jsvutil module provides a simple framework around JSV for validating JSON instances and checking JSON schemas.
Features
This module augments JSV with the following features:
 1. A validate function that combines JSV report errors into a single Error exception instance.
 2. Applies any default values in the schema to the instance being validated.
 3. A check function that validates a schema.
 4. Supports callback functions as well as standard exceptions (useful in Node.js environments).
Installation
$ npm install jsvutil
Examples
The following two examples illustrate how a configuration file can be validated. Note that the validate function applies the default values in the schema so that after validation, the config object returned by the validate function may be different than the one read using the require function.
Using Exceptions
var jsvutil = require('jsvutil')
var config = require('./config.json');
var schema = require('./schema.json');
try {
 config = jsvutil.validate(config, schema);
 console.log('config file is valid');
} catch (e) {
 console.error(e.message);
 process.exit(1);
}
// Use the config object...
Using Callbacks
var jsvutil = require('jsvutil')
var config = require('./config.json');
var schema = require('./schema.json');
jsvutil.validate(config, schema, function (err, config) {
 if (err) {
 console.error(e.message);
 process.exit(1);
 } else {
 console.log('config file is valid');
 }
});
// Use the config object...
API
This section specifies the Application Programming Interface (API) for the jsvutil package. The API consists of the validate and check functions.
Important: If the instance or schema parameter is a string, then it is parsed as JSON text using the JSON.parse function. Otherwise, it must be a JSON-compatible JavaScript object or array. This is consistent with RFC 4627 and inconsistent with ECMAScript 5 § 15.12, which allows strings as top level productions.
The optional callback function complies with Node.js conventions. The first argument is either an error object on failure or null on success. The second argument is the equivalent return value of the function.
validate (function)
validate(instance, schema, [cb])
Validates the specified instance against the specified schema. The return value (or callback value) is the JSON instance with any schema default values applied to any unset instance values. The original instance parameter is not modified by this function.
Parameters:
 - instance - {String|Object|Array} The JSON instance to validate. The instance is parsed using the JSON.parse function if it is a string.
 - schema - {String|Object} The JSON schema against which to validate the instance. The schema is parsed using the JSON.parse function if it is a string.
 - [cb] - {Function} The optional cb(err, instance) callback function.
Returns:
 - {Object|Array} The validated JSON instance with any schema default values applied to any unset instance values.
Errors:
 - Throws an error (or passes it to the callback function) if the specified JSON instance cannot be validated.
check (function)
check(schema, [cb])
Checks that the specified schema is valid.
Parameters:
 - schema - {String|Object} The schema to check. The schema is parsed using the JSON.parse function if it is a string.
 - [cb] - {Function} The optional cb(err, schema) callback function.

The defensive team
in American football
or Canadian football
, is the team that begins a play from scrimmage
not in possession of the ball.
Several different "defensive sets" are used. The numbers of linemen and linebackers will vary, but most sets used in American football include a line composed of defensive ends and defensive tackles and, behind the line, linebackers, cornerbacks, a strong safety and a free safety.
- defensive end - the two defensive ends play on the outside of the defensive line. Their function is to rush the passer or stop runs.
- defensive tackle - (sometimes called a defensive guard), defensive tackles are linemen who lines up inside the defensive ends. Their function is to rush the passer, and defend against running plays. A defensive tackle that lines up directly across from the ball (on the nose of the center) is often called a nose guard. Common defensive sets have from one to three defensive tackles.
- linebacker - linebackers play behind the defensive line and perform various duties depending on the situation, including rushing the passer, covering receivers, and defending against the run. Most defensive sets have between three and five linebackers.
- cornerback - the cornerbacks primarily cover the wide receivers.
- safety - the safeties are the last line of defense (farthest from the line of scrimmage), and provide help on deep pass coverage.

Manage Multiple Social Accounts-01
By nature, social media managers are multitaskers. They're constantly juggling the need to engage with customers, publish new content, analyze success, monitor conversions, report to stakeholders and–if time allows–sleep. Not only do most social media managers have to complete these activities, but many of them do all of that work for multiple social profiles and networks.
What drives this need for multiple social media profiles and networks? Surely companies aren't creating superfluous accounts to generate more work for their communications teams.
This article is going to dive into which circumstances companies would need multiple social media accounts, give some examples of specific business types that benefit from a larger presence and most importantly, look into how you can effectively manage multiple social media accounts.
Why Do You Need Multiple Social Accounts?
Creating multiple social media accounts gives you much more control over the type of content that corresponds to various products, locations or departments of your company. We'll get into examples of specific organizations that frequently use multiple social media profiles, but here are a few reasons why a company may go that route.
 - Multiple products – if you have several different popular products that get asked their own questions or that need to create their own content.
 - Multiple locations – if you have multiple locations that all offer different promotions or have different hours that need to be shared.
 - Different goals – different portions of your business may have their own unique goals when it comes to social, and may require a different strategy.
 - Different social voices – each product or portion of your business may have a different "social voice." For instance, one brand voice may err on the serious side, while another could have the chance to be more humorous and lighthearted.
 - Different teams – each team within an organization–like customer service, human resources, or research & development–may want their own social presence to better control the flow of conversations and content.
Those are just a handful of the many reasons why companies may want to create multiple profiles on each social network. To paint a better picture of this, it's helpful to look at specific examples of who needs multiple accounts.

Who Needs to Manage Multiple Social Accounts?
The idea of creating multiple social media pages may seem trivial–you're essentially just creating more work for yourself–so who would do it? There are a lot of reasons why a company may want to split their online personalities into multiple social media pages.
1. SMBs
The most common reason a smallor medium-sized business creates multiple social media pages is to separate unique portions of their business. A company may give their blog a separate handle so they can distribute their content more frequently to those that want to read it. SMBs may also give their customer support team a separate handle so their main page isn't bogged down with customer service issues.
2. Corporations
Corporations could use multiple pages for the same reasons as SMBs, but there are a few more use-cases unique to this group. Some corporations, for instance, could use the social media profiles of a C-level employee to share company-wide news and updates.
Corporations could also create new profiles for some of their different departments–like human resources, R&D or finance–who can handle the messages better suited for their team.
3. Franchises
A lot of major corporations with several locations will create unique social profiles for the various branches of their business. McDonalds, for instance, has several location-based Twitter pages, including accounts for different countries, states and cities.
This gives the franchises the freedom to post about exclusive deals, operating hours or contests that the entire organization may not participate in. That frees up the corporate pages to continue creating content that advocates for the success of the individual franchises.
4. Agencies
The whole idea of agencies is that they can manage the work for multiple companies all at once–freeing those companies to work on the other functions of their business. So, it should come as no surprise that most agencies need to manage multiple social media profiles simultaneously. Some of the larger agencies can even be responsible for handling hundreds of different social pages at once.
5. Universities
This is one of the most popular use-cases for needing multiple social media profiles. Universities have so many different sub-organizations with different needs and voices that could require unique social media pages.
Here are a few more instances of different social media accounts universities could own:
 - Student clubs and organizations
 - Student services, such as housing and dining
 - Student newspapers
 - College programs
 - Libraries and buildings
 - Residence halls
 - Alumni groups
 - Emergency notifications
 - Athletics
 - Even accounts for the mascot!
Another example would be Harvard, which has more than 100 different social media profiles built out for the various organizations at their university.
How to Manage Multiple Social Media Accounts
At a high level, the key to managing multiple social media accounts simultaneously is to utilize a single stream social media management platform. The functionality to handle multiple pages all at once just isn't available on most networks, especially when you're talking about combining multiple social media sites such as Instagram, Facebook, Twitter and LinkedIn. At Sprout Social, we've created our own social media software for handling these exact needs.
We feel like we have a good idea about what makes social media managers tick. Our platform was built to make managing multiple social profiles easier, especially when there are several accounts tied to a single business.
If you're interested in diving into the platform to test it for yourself, check out our completely free trial–no need to download any software or enter credit card information.
Engaging on Multiple Social Media Accounts
The most important thing you can do on social media is engage with your current and prospective customers in order to build lasting, profitable relationships. However, that can be difficult when you're managing several social network accounts across different platforms. Without any sort of tool, you'd find yourself constantly logging in and out of your various pages to find and field important messages.
That's a lot of time spent entering email addresses and passwords, which can be annoying when doing it just once. Additionally, you run the risk of accidentally promoting one social profile while logged into the other–or even worse–post personal social messages on corporate feeds.
You need a way to centralize the messages sent to all of your social profiles and that something could be Sprout Social's Smart Inbox.
You can easily work your way through every message sent to all of your profiles by yourself, or with a team, and mark them as complete as you go. This will help ensure you never miss an important social interaction.
Publishing to Multiple Social Media Accounts
Most of the different pages you manage require unique content, because what's relevant for one audience may not be relevant for another. Without a social media tool, it could take all of your time finding, creating and sharing content across multiple different accounts.
However, with Sprout Social you can queue, schedule and publish all of your content to multiple social media networks simultaneously from within the platform. This will save you countless hours you could have used to engage with customers to grow relationships.
Analyzing Multiple Social Media Accounts
With social media marketing, it's important to look at what has worked in the past so you can utilize that success moving forward. Analyzing the data you have at hand is key in creating more successful campaigns moving forward. Unfortunately, collecting and analyzing data for multiple pages is cumbersome.
Sprout's social media analytics suite makes it easy to view your data on a profile level so that you can see what specifically works for your individual social pages. Not only that, but you can combine that data with our group and roll-up reports to see what is working across all of your profiles and campaigns.

Collaborating on Multiple Social Media Accounts
The key to managing multiple social media profiles is teamwork. Even if you can't convince your company that you need more social media managers, try recruiting some internal teams to help out when queries come in relating to their department.
Sprout's collaboration was made for multiuser teams to work within all at once. Manage the Smart Inbox as a team, create internal notes, task specific messages to the proper departments, run reports to see how everyone is performing, and take out all of the stress of double-responding with collision detection features.
Get Managing
There are plenty of reasons why a company may need manage multiple social media accounts, and without the right management platform, things can get hairy. So try and figure out which parts of your organization would thrive with their own social media presence and get them established online. Once these members have their own space to work, they can work freely in your social media management platform!

Some distinction can be made interpreting data in a spectrogram. An easier and quicker way to distinguish orders and quantify the acoustic emissions is an analysis based on orders (order analysis). NoiseImage 4 and the Order Analysis module allow to calculate acoustic maps via ordergram, order line selection in the spectrogram (Figure 1), or order spectrum (Figure 2). This gives way to fast analysis of all-sizes machines ranging from large scale infrastructure as shown to small items in the range of centimeters.
Based on the analysis results, you are enabled to quickly localize noise emissions and e. g. compare prototype iterations. The results also allow to narrow down regions of interest for more detailed testing including vibration analysis and troubleshooting of resonance effects.
The array used in this example can be used for testing on ground level as well as for suspended operation using a crane e. g. to cover the top view. It is foldable for transport.
The powerful data recorder collects data at 192 kS/s of up to hundreds of channels including individual microphones, accelerometers and rotational speed sensors. Analyses can be automated by the Project Manager. This NoiseImage module allows you to transfer measurement and analysis configurations to entire measurement campaigns.


To set up an audition, actors should be contacted by email (see sample email) and sent a copy of the script along with the role you would like them to read for. Five-to-seven actors per role. You should then follow-up with a phone call to make a personal connection and make sure there is no confusion about your expectations. Let them know what pages of the script you would like them to prepare for the audition.
How to Choose Sides for Auditions
 1. Sides should ideally have two characters, but no more than three.
 2. The best sides give the actor a chance to act and react. Therefore, exposition is not a good choice.
 3. Do not choose scenes that are primarily action. If you must see an actor move, give them an improv that is directed (called out).
 4. Sides should be no more than two minutes, preferably closer to one minute.
 5. Sides may be from a script that is not your own if it contains similar characters and situations.
 6. Sides may be specifically written for audition purposes to satisfy the recommendations above. For example, if your character does not speak, you could write an interview of that character for sides. This is a good way to verbalize how a character is feeling. Or, think about if you were making your film into a longer form piece. What scenes do you wish you could write? Write them for sides!

VariableTypeNode
VariableTypes are used to provide type definitions for variables. VariableTypes constrain the data type, value rank and array dimensions attributes of variable instances. Furthermore, instantiating from a specific variable type may provide semantic information. For example, an instance from MotorTemperatureVariableType is more meaningful than a float variable instantiated from BaseDataVariable.

 UA_NodeHead head;
 UA_NODE_VARIABLEATTRIBUTES
 UA_Boolean isAbstract;
 /* Members specific to open62541 */
 UA_NodeTypeLifecycle lifecycle;
} UA_VariableTypeNode;
MethodNode
Methods define callable functions and are invoked using the Call service. MethodNodes may have special properties (variable children with a hasProperty reference) with the QualifiedName (0, "InputArguments") and (0, "OutputArguments"). The input and output arguments are both described via an array of UA_Argument. While the Call service uses a generic array of Variant for input and output, the actual argument values are checked to match the signature of the MethodNode.
Note that the same MethodNode may be referenced from several objects (and object types). For this, the NodeId of the method and of the object providing context is part of a Call request message.
typedef UA_StatusCode
(*UA_MethodCallback)(UA_Server *server, const UA_NodeId *sessionId,
 void *sessionContext, const UA_NodeId *methodId,
 void *methodContext, const UA_NodeId *objectId,
 void *objectContext, size_t inputSize,
 const UA_Variant *input, size_t outputSize,
 UA_Variant *output);
typedef struct {
 UA_NodeHead head;
 UA_Boolean executable;
 /* Members specific to open62541 */
 UA_MethodCallback method;
#if UA_MULTITHREADING >= 100
 UA_Boolean async; /* Indicates an async method call */
#endif
} UA_MethodNode;
ObjectNode
Objects are used to represent systems, system components, real-world objects and software objects. Objects are instances of an object type and may contain variables, methods and further objects.
typedef struct {
 UA_NodeHead head;
 UA_Byte eventNotifier;
} UA_ObjectNode;
ObjectTypeNode
ObjectTypes provide definitions for Objects. Abstract objects cannot be instantiated. See Node Lifecycle: Constructors, Destructors and Node Contexts for the use of constructor and destructor callbacks.
typedef struct {
 UA_NodeHead head;
 UA_Boolean isAbstract;
 /* Members specific to open62541 */
 UA_NodeTypeLifecycle lifecycle;
} UA_ObjectTypeNode;
ReferenceTypeNode
Each reference between two nodes is typed with a ReferenceType that gives meaning to the relation. The OPC UA standard defines a set of ReferenceTypes as a mandatory part of OPC UA information models.
 - Abstract ReferenceTypes cannot be used in actual references and are only used to structure the ReferenceTypes hierarchy
 - Symmetric references have the same meaning from the perspective of the source and target node
The figure below shows the hierarchy of the standard ReferenceTypes (arrows indicate a hasSubType relation). Refer to Part 3 of the OPC UA specification for the full semantics of each ReferenceType.

nope. You would have to jump up to cancel out the downward speed of the falling helicopter. … Even if you were to be able to somehow cancel out all motion (which is probably not possible), there is going to be a lot of wreckage strewn about in a helicopter crash, especially if the rotors are still turning.
Can you wear a parachute on a helicopter?
Helicopter pilots do not wear parachutes but there are a few helicopters with parachute rescue systems. Most helicopters operate low-level and to safely exit a helicopter and parachute away would require altitude and a safe route away from the main rotor system. Both are never really available.
Can you parachute out of a crashing plane?
Yes. It's called "bailing out". During WWII, fighter pilots and bomber crews of every nation wore parachutes so that they could escape from crashing aircraft. Today, the norm is for aircrew to use ejection seats.
Why can't helicopters have parachutes?
The number of times planes lose their wings in circumstances in which you could deploy a parachute is effectively zero. Extra weight and cost for something that would never be used. Rotors fail more often, but the difficulty of deploying a parachute when you have got a rotor makes them not sensible.
Do helicopter crash victims die instantly?
The graphic report made it clear: Bryant and the passengers almost certainly were dead in an instant due to blunt trauma. "These injuries are rapidly if not instantly fatal," wrote Juan Carrillo, senior deputy medical examiner, in Bryant's report.
Do pilots wear parachutes?
Sometimes pilots do wear parachutes. It is a requirement for aerobatic flight that all occupants wear emergency parachutes. … The seats in the aircraft are also designed to accommodate an emergency parachute which doubles as a backrest or seat cushion.
Is it better to crash on land or water?
On land, the plane has no risk of flooding or sinking, and its occupants have no risk of drowning. If you're on a plane with total engine failure, the pilots will try everything to land you on a runway. If, and ONLY if, their efforts fail, water is your best shot.
Can you jump out of a plane right before it crashes?
In a plane crash, the plane and the people in the plane are moving at the same speed. … It doesn't help to jump right before landing because you are going the same speed as the elevator. Plane crashes on commercial flights are incredibly rare.
Do you die instantly in plane crash?
Some airplane crashes happen with the plane colliding with a mountain at a couple of hundred miles per hour. In such an accident, everyone will likely die instantly. Other airplane crashes are of the variety where the pilot has some control and the plane slows down and hits the ground moving until it comes to a stop.
Why didn't Kobe have a parachute?
—they had no time to put parachutes on, —they certainly had no training on how to use parachutes, —and ads-b shows that the helicopter was going 120 to 160 mph which is really too fast for inexperienced jumpers.
What do helicopter pilots wear?
For instance, you'll likely wear a helmet, gloves, and a flight suit. Flight suits are designed to keep you warm while flying at high altitudes, and most flight suits are also flame retardant to protect your skin from burns in case of a fire.
What are the chances of surviving a helicopter crash?
Of these, 119 occupants (26%) did not survive; of those who did survive, 38% were injured. Twelve died after making a successful escape from the helicopter.
How did Vanessa Bryant Find out about Kobe's passing?
Vanessa Bryant learned about the crash from an employee of Kobe Inc., but was told there were survivors. She then received Instagram messages, expressing condolences. "Mrs.
What kills you in a plane crash?
In almost every crash, there are some who survived — or probably survived — the actual crash. In fact, the vast majority of accident deaths occur after the actual crash. Most of those subsequent deaths are due to fire and smoke inhalation. … Most of those subsequent deaths are due to fire and smoke inhalation.


Herman Wouk, a novel force
From 'The Caine Mutiny' to 'The Winds of War' to his latest, 'The Lawgiver,' he's made his mark in American letters.
Herman Wouk
Herman Wouk (Patrick Ecclesine)
The year Herman Wouk was born, Woodrow Wilson was in his first term in the White House, the Lusitania's sinking was on the front page and "The Birth of a Nation" was playing in silent movie theaters. In the 97 years since, with such books as "The Caine Mutiny," "Marjorie Morningstar and "The Winds of War," Wouk became a force in American letters, and in film and television as well. His latest novel, "The Lawgiver," tells the tale of a Hollywood struggle to make a movie about Moses. Wouk's modern story about the ancient and long-lived biblical hero unfolds via text messages, emails and plain old-fashioned letters. And he's made himself and his late wife, Betty Sarah, characters in the book. Wouk is a devotee of Skype, which is how he talked to me from his Palm Springshome.
So many towering characters in the Bible — David, Solomon. Why did you choose Moses?
When I first started, I was a comedy writer for Fred Allen. Out at sea [during World War II], I had plenty of time to think, and I decided to write a lightweight novel, "Aurora Dawn," and it did fairly well. So I was in the novel-writing business. Then I wrote "The Caine Mutiny." I discovered a narrative power I didn't know I had. I was going to be a funny writer, but here I was doing something dramatic and panoramic. I have a very strong Jewish background, and I rediscovered in the five books of Moses the greatest narrative ever written. My thought was someday I'll write a novel about Moses. As I wrote more serious, more ambitious books, I discovered I couldn't write a novel about Moses because there's no narrative that equals [the Bible's].
So I gave up on that for many years. But [after] my last book was published, I thought, what about a new book? By not making it a narrative, just doing it as somebody trying to [make a Moses movie]. That's Hollywood. I've heard there are a couple of Moses movies in the works. I even thought, as I was writing "The Lawgiver," well, suppose one of those comes out in the meantime? What does it matter? I'm doing my version.
Were you able to say things about Hollywood and yourself that you couldn't do in a traditional narrative novel?
That's right. Of course, I have mixed feelings about Hollywood, depending on how my work has turned out. I thought "The Caine Mutiny" movie was quite good. I don't want to mention the ones that were terrible. Dan Curtis, the best of the TV directors, we got together and we made a great match. I wrote the screenplays [for "Winds of War" and "War and Remembrance"] mostly directed by him. They were very long — 18 hours for "Winds of War." He kept telling me, cut out the history! They won't sit still for the history! But I pushed him on the history and he pushed me on the story, and it came out very well together.
Moviemaking is, shall I say, a very intense and self-absorbed process.
That's in the nature of not onlyartbut entertainment. I've done plays on Broadway; nothing else matters while that show is on. I'm a Sabbath observer, and I would leave for 25 hours and they'd plead, don't go away, the show is going to collapse! Twenty-five hours later it's going on the same way, the tearing of hair is the same. Anything you're really engaged in, particularly entertainment, where you face the public — it's in the nature of it to be intense. If you're not intense about it, it shows up on screen, in the play, in the novel too.
This book is composed of text messages, emails, notes of conversations — is there any future for sustained literary fictional narratives?
Whatever form it takes, storytelling will exist, and words are the medium. In film and theater you have the staging to help the story along. In a novel, all you have are the words. But there's magic in words. And one way or another, a writer who has a story to tell, like "Jane Eyre," will find a way to tell it in words. And one way or another, through Amazon or the Nook or whatever, it will show up.
Frankly, I'm very glad that there was a window in time 30 or 40 years ago when I was able to write long novels and be reasonably sure they would be read. It's an incredible business, sitting down and saying, well, I will now write "The Winds of War," it'll be 1,000 pages long, and somebody's going to print it and somebody's going to read it.
Your literary generation includes names like Norman Mailer and Saul Bellow.
I've never discussed in public or in print any of my contemporaries. It's just a rule of mine and I've stayed with it. Generally speaking, it was a pretty good generation of writers.
Whose work influenced you?
One that was very strong was "Tristram Shandy" by Laurence Sterne. It was the first anti-novel; it takes the novel and turns it inside out. There's no direct narration at all — it's all skipping around and intensely personal. The idea of the anti-novel, the story told by not being told, that's very sophisticated. When it came to doing the Moses novel, I figured the only way to tell it was not to tell it.
You were born in New York but came west decades ago.
The first time I saw the West was when Fred Allen came out to do a movie. I was writing for him then. [We] came out on the Super Chief; it was something — two or three days between Chicago and L.A. and the food was incredibly wonderful. To see the West for the first time from the Super Chief was a pleasurable thing.
Did you have an epiphany that you belonged here?
Not exactly. It was more of a "Wow! Paradise!" Until we got off the train and ran into the smog.
You met your future wife in L.A. during the war.

Do you have the new version of the Guidance Automation Toolkit and the Guidance Automation Extensions installed? Well, then it's time we take off on a trip into the "zone" just like Thomas likes to say… In this case, we're leaving to the "guidance-zone"!
So what are the possibilities? What kind of guidance package do we want to develop? What audience will it target? What procedures will it automate? That's a whole set of questions we have to answer before starting the development phase. But we have to do something else too… Before you can start off experimenting fully with the Guidance Automation Toolkit, there are some basic concepts that one should understand well so we can take full advantage of the capabilities of the toolkit.
One of the first concepts, a true GAPD (Guidance Automation Package Developer) should master, is the diference between bound and unbound recipes. When do we use bound recipes, or when do we choose to implement unbound recipes? …
Some basic things to know…
The goal of a recipe, is automating a serie of actions, that are normally manually performed by a developer in each project. Using a recipe will ensure that these series of actions will be performed correctly and consistently. A recipe, can trigger a number of actions which have to be defined within the recipe. You can use an existing action (meaning one provided by the Recipe Framework) within the XML-file, or you can develop your own custom actions. The only key to defining your own actions, is making them inherit the Microsoft.Practices.RecipeFramework.Action-class.
More information and an example of developing actions, will follow later…
In most of the cases, a recipe needs a set of arguments to execute its actions. These arguments can be either required or optional. We can gather these arguments in two different ways: we let the user define the argument's value using a wizard or we can use value providers, which are implementations of interfaces that can be used by the framework to gather arguments. The strength of value providers lies in the ability to intercept changes in other arguments, so you always obtain a value that's completely up-to-date. Value providers implement the Observer pattern in this way. When an argument which is observed, changes it's value, it notifies all the arguments that are observing it, so they can update their values.
Getting to the different recipe types
As we all have derived from the title by now, there are two kind of recipes within the Recipe Framework: bound and unbound recipes.
A bound recipe, is a recipe that is associated with a specified Visual Studio solution element. This can be a solution, a project, a class file… The recipe will only appear in the context menu on the item you have specified to bound it to (only on solution level for example).
A bound recipe can again be recurring or non-recurring.
Easily said: a recurring recipe is like a recipe to add a test class, it wil contain a basic test method from which to start, it wil contain the correct namespace references to get you started, and so on… You can add as many test classes as you want, meaning that that specific recipe, is recurring.
When using a non-recurring recipe, once the recipe is executed, you can't choose to execute it again. A case scenario in which you would want to create a non-recurring recipe is when you want to create a static gateway. Imagine this static singleton class only serves to hold single instances of objects and provide it for usage in other classes using properties. We could develop a recipe that would create this class, for all objects you want to instantiate just once (you could let the user choose these classes in a wizard for example). You only want to create this static gateway once, so once the recipe is executed, it is never again available. It's possible you would want to regenerate this static singleton class, adding more or less objects in the wizard, but let's assume in this case, you would do this in a phase of your project where this decision can't vary.
Bound recipes are bound to a bound recipe reference. A bound recipe reference is an object used by the Recipe Framework to associate a particular recipe with a particular launch point – or speaking in Visual Studio terms, a command. The reference enables the recipe to be executed, and stores it's state (for example, has it been executed already?).
On the other hand, we have unbound recipes. Unbound recipes aren't asociated with any item within Visual Studio. The recipe is not "placed" on solution-, project-, nor item-level. These kind of recipes work in a whole other way. Unbound recipes are associated with unbound recipe references, and these references, selects the solution items it's associated with or used in.
As I just said, the unbound recipe reference chooses the solution items to appear on, but it does this according to a selection condition, a so called Target Condition. This condition is written in code, thus it is defined by us, the GAPD's. It can be a simple condition and be satisfied by a very broad number of scenarios, or quite complex thus only satisfied in very specific cases. A TargetCondition is a piece of code returning a boolean value which specifies whether the condition was met or not.
Let's discuss a concrete example. You're developing a guidance package, which contains a number of folders inside the Domain-project that you have predefined for usage. Since you specify an "Exceptions" folder, you want all the custom Exceptions placed inside this folder, that's obvious. You also developed a start for custom Exception classes, which you defined as "Exception class" (which is the same as a normal class, but already inherits the ApplicationException class and contains the correct namespace instead). You only want Exception classes within the specific Exceptions-folder, but how do we enforce it???
Well, this is where the unbound recipes come to the rescue. You write a simple condition in code, which checks if the item on which the user clicked is a folder, and also checks it name…. If the recipe is satisfied, an extra command appears in the context menu of that folder: "Add new Custom Exception class".
How does VS deal with this?
Actually I really wondered how this worked when I started with GAT. When we register a guidance package, one of the main things that happen, is that Visual Studio is told what commands we want to specify on each item in Visual Studio. In the Visual Studio world, this is not dynamic. The commands are loaded before the package, thus Visual Studio needs to know what "icons" it has to display on context-menu's before anything. That's why the registering process is so important (of course, this is not the only reason). The action behind the command, that's where the guidance package comes to the scene. Olaf Conijn explained this to us on the VISUG-event about Software Factories we had a while ago.
So, what about the unbound recipes? How could this be predefined? They actually seem quite dynamic since the commands to unbound recipes are only shown if the condition was satisfied… Well, every time a solution element is selected, Visual Studio queries the Recipe Framework and calls the TargetCondition of each unbound recipe in the package. If the condition returns true, the corresponding command is displayed in the context menu. In the last sentence, I want to emphasise "displayed in the context menu". VS uses dynamic visibility for unbound recipes. When registering a package, the items on which the unbound recipes can be available, are in deed registered. But it's when such an item in VS is clicked, that VS adjusts the visibility of commands according to the TargetCondition of the unbound recipes.
Summary
So, I think -and hope- you now understand the difference between bound and unbound recipes.
To summarize it in a sentence, a bound recipe is a recipe attached to a particular item in your project while unbound recipes aren't attached to any item, but contain a serie of conditions which in combination decide whether you can or not execute the recipe in a certain scenario.
Stay tuned for more GAT-talks!

GAT/GAX – Creating a guidance package
14 06 2008
In this post we will start of with our Domain Driven Design Software Factory, the first step is obviously creating the package itself. But before we commence, I need to give some credits to my former colleague Jelle Druyts as this post is blatant plagiarism of his blog post from back in the year 2006 … but at least the pictures of this post are based on the 2008 edition of the Guidance Automation Toolkit.
To start of creating your own package, you can make use of a guidance package specifically designed for creating other guidance packages. That's what I call eating your own dog food. So let's generate the source for our package in a solution called Factory, which can be obtained in its current form from our codeplex team project.

The second part of this wizard allows you to set some package options like the package name, the namespace and some other information. Make sure not to include spaces in the package name as that will give issues later on.

There's water on comets. But not water water. A different kind of water, unlike that on earth. So where did Earth's water come from? The Huffington Post and others want to know:
Where did the Earth get its water? For years some scientists have argued that it was brought here by water-bearing comets that smashed into our planet during its infancy. But new data from the European Space Agency's Rosetta mission suggest that that theory is all wet.
The data show that the chemical signature of water found on Comet 67P/Churyumov-Gerasimenko differs significantly from that of the water found on Earth. (Comet 67P's water contains about three times more of the heavy hydrogen isotope deuterium than does terrestrial water.) And that has Dr. Kathrin Altwegg, the principal investigator for the Rosetta instrument that collected the data, arguing that it's unlikely that comets brought water our way.
So what – or who – brought good old H20 to earth?
Instead of comets, Altwegg said in a written statement, it could have been asteroids. She said that while asteroids today contain limited amounts of water, that probably wasn't the case billions of years ago, according to The Guardian.
Next question: who put the water in the asteroids? Or is it comets and asteroids all the way down?
Meanwhile back on the idiot front:

Federal District Court in Kentucky Enjoins Application of Governor's Order to Drive-in Church Services
Written by: Ken Ciccoli
As a response to the ongoing coronavirus pandemic and to further emphasize Kentucky's social distancing order, on April 9, 2020, the mayor of Louisville, Greg Fischer, ordered police forces to dismantle all in-person church services. This order, issued four days before Easter, banned even "drive-in" gatherings in which practitioners were poised to stay in their vehicles throughout the entire service. On Fire Christian Center (OFCC), having already planned a drive-in Easter service, filed a temporary restraining order, seeking injunctive relief from the United States District Court for the Western District of Kentucky to stop the mayor from carrying out his restrictive interpretation of the State's social distancing order. The district court granted the temporary restraining order, holding that despite his good intentions, the mayor's order was unconstitutional.
The court opened its opinion with an overview of the long and sordid history of religious persecution in the United States. It began with the plight of the Pilgrims and their quest to be free of religious prosecution. It then detailed instances when religious freedom has been neglected in American history, such as slaves being beaten for attending prayer gatherings, the disparaging treatment of Mormons, and the exclusion of Jewish students from universities.
After that emotional introduction, the court applied a four-part test for determining whether to issue a temporary restraining order. First, the court determined first that OFCC had a strong likelihood of success on the merits on both its Free Exercise claim and its statutory claim under Kentucky's Religious Freedom Restoration Act. The Court held that the mayor's order likely violated the church's free exercise rights because the mayor's order was non-neutral between religious and non-religious conduct and therefore triggered strict scrutiny. The order was discriminatory because it forbid drive-through religious services while permitting non-religious drive-through arrangements, including those of liquor stores and ice cream shops. The court also found that the Kentucky Religious Freedom Restoration Act barred enforcement of the order.
Having found that OFCC was likely to succeed on the merits, the court then explained why OFCC would suffer irreparable injury without a temporary restraining order. "The loss of First Amendment freedoms, for even minimal periods of time,'" the court said, "unquestionably constitutes irreparable injury." Additionally, the balance of equities tipped in OFCC's favor, the court held, because churchgoers would be giving up a fundamental right by skipping church services (or facing arrest if they did attend). Finally, the court explained that an injunction is in the public interest because there was no evidence that drive-through church services were more likely to spread the coronavirus than other open parking lot arrangements permitted under the order.
The United States District Court for the Western District of Kentucky concluded by admitting that while its decision might be disagreeable to many, it was one meant to protect OFCC's, and other believers' right to practice their Christian faith, as guaranteed by the First Amendment.
Supreme Court, in a 5-4 decision, refuses to stay the application of California occupancy limits on religious worship services
Written By: Lea Solakian
California Governor Gavin Newsom's Executive Order limits the attendance at places of worship to a 25% capacity or a maximum of 100 attendees while exempting secular businesses such as grocery stores and banks from any capacity limit. In response to this discrepancy, South Bay Pentecostal Church sought to enjoin application of the law to in-person religious services. A district court declined to order emergency relief, and the Ninth Circuit subsequently denied the Church's motion for injunctive relief pending appeal. On May 29, 2020, the Supreme Court, by a 5 to 4 vote, summarily denied the Church's application for temporary injunctive relief. Chief Justice John Roberts wrote a concurring opinion for himself, and Justice Kavanaugh wrote a dissent to the denial of the application, which was signed by Justice Clarence Thomas and Justice Neil Gorsuch.
Chief Justice Roberts, in his concurring opinion, stated that the Order does not run afoul of the Free Exercise Clause under the First Amendment. Although not expressly stated, Roberts implicitly found that the California Order was a neutral law of general applicability that was not targeted at religious practice. Analogizing places of worship to the shut down and secular businesses like concert halls and movie theaters, he noted that all result in large groups of people gathering in long term close contact. Moreover, he distinguished the exempt secular businesses under the Order, such as laundromats and banks, in that people neither convene in large groups nor remain in close proximity for a long time. "Our Constitution principally entrusts '[t]he safety and the health of the people' to the politically accountable officials of the States 'to guard and protect.'" South Bay Pentecostal Church v. Newsom, No. 19A1044, slip op. at 2 (Roberts, J., concurring) (quoting Jacobson v. Massachusetts, 197 U. S. 11, 38 (1905)). Thus, he determined that Governor Newsom's actions are wholly constitutional.
In sharp contrast, Justice Kavanaugh dissented, finding that the Order violated the First Amendment by discriminating against religious practice. He stated that the problem with the Order is that similar secular businesses such as pharmacies and grocery stores are not subject to the 25% occupancy cap. What is more, he pointed out, is that the Church is willing to follow social distancing guidelines that apply to these similar secular businesses. He noted that although states have the authority to "draw lines" during an emergency, the Constitution forbids states from discriminating against religion. South Bay Pentecostal Church v. Newsom, No. 19A1044, slip op. at 2 (U.S. May 29, 2020) (Kavanaugh, J., dissenting). There are other nondiscriminatory ways that California could mitigate the spread of COVID-19, Justice Kavanaugh detailed. For example, California could mandate that places of worship abide by social distancing guidelines or impose an occupancy limit on all businesses. However, absent a compelling justification for this disparate treatment, he believes that California cannot merely assume that the spread of the virus will worsen by sitting in a church pew as opposed to walking down a grocery store aisle. Ultimately, he concluded that enforcing the Order will cause the Church irreparable harm by not being able to conduct its Sunday Services.
Maine District Court Upholds Gathering Limits for Churches
Written by: Nathaniel Belluso
The United States District Court for the District of Maine recently denied injunctive relief to Calvary Chapel of Bangor, which had sought an exemption from the governor's order limiting public gatherings. Due to the COVID-19 pandemic, the governor of Maine put in place several orders attempting to reduce the spread of the virus and reduce possible infection. These orders include the "Gathering Orders," which prohibited "gatherings of more than 10 people … throughout the state." Calvary Chapel of Bangor v. Mills, 1:20-CV-00156-NT, 2020 WL _PHONE_, at *4 (D. Me. May 9, 2020). There was also orders for when the state began opening up its economy, called "Restarting Maine's Economy," in which churches were allowed to conduct "limited drive-in, stay-in-your-vehicle church services." Id. at *3. Depending on the spread of the virus, churches might eventually have the opportunity to conduct services with up to 50 people depending on the state of the virus.
Calvary Chapel petitioned the Court for injunctive relief claiming that these orders violated their Free Exercise rights under the First Amendment by not allowing them to conduct their services as usual (with more than 10 people). Chapel argued that these Orders were not neutral laws of general applicability but instead targeted places of worship. Chapel contended that the laws were not generally applicable because they did not apply to many secular businesses such as liquor and grocery stores, which were allowed to operate with more than 10 individuals present at the same time. Id. at *5, *8.
The Court began its analysis by stating the governor's orders did not place a "significant burden on Calvary Chapel's religious beliefs." Other courts around the country have held that an occupancy limit on places of worship to no more than 10 people and a ban on allowing for drive-in services do not violate the First Amendment. Id. at *7. "A community has the right to protect itself against an epidemic of disease which threatens the safety of its members" and during an ongoing national emergency, the "traditional tiers of constitutional scrutiny do not apply." Id. (quoting Jacobson v. Commonwealth of Mass., 197 U.S. 11, 27 (1905)). Jacobson instructs courts to overturn state action, such as Governor Mills' orders, when it lacks a "real or substantial relation to the protection of the public health." Id. Ultimately, the Court found that the Orders in Maine were necessary to protect its citizens from the spread of COVID-19.
Under the traditional Free Exercise analysis, "'neutral, generally applicable laws' that do not target religious practice are subject to a rational basis review." Id. A law would violate Free Exercise if it was enacted "because of religious practice" and intended to

Northern Crayfish Frog
The northern crayfish frog grows to a length of nearly four inches. It has dark round spots surrounded by light borders on its chin, and the back is noticeably humped. This somewhat stubby frog lives in the southern half of Illinois and is closely associated with the hardpan clay soils south of the Shelbyville Moraine. This nocturnal frog spends the daytime hiding in crayfish or other animal burrows or under boards or logs in wet prairies, pastures or golf courses. It lays its eggs from early March to mid-April in flooded fields, farm ponds and small lakes. The call of the crayfish frog carries a considerable distance. It resembles a deep, roaring snore.

The Impact of the Adversary's Eavesdropping Stations on the Location Privacy Level in Internet of Vehicles
The Internet of Vehicles (IoV) has got the interest of different research bodies as a promising technology. IoV is mainly developed to reduce the number of crashes by enabling vehicles to sense the environment and spread their locations to the neighborhood via safety-beacons to enhance the system functioning. Nevertheless, a bunch of security and privacy threats is looming; by exploiting the spatio-data included in these beacons. A lot of privacy schemes were developed to cope with the problem like CAPS, CPN, RSP, and SLOW. The schemes provide a certain level of location privacy yet the strength of the adversary, e.g., the number of eavesdropping stations has not been fully considered. In this paper, we aim at investigating the effect of the adversary's eavesdropping stations number and position on the overall system functioning via privacy and QoS metrics. We also show the performances of these schemes in a manhattan-grid model which gives a comparison between the used schemes. The results show that both the number and the emplacement of the eavesdropping stations have a real negative impact on the achieved location privacy of the IoV users.
