At restaurants with multiple locations, it is common that one user may need to make changes to another user's Permissions, Basic Information, and Jobs and Wages at another location.
This article will cover the requirements for a user to make changes to Employee Information, Jobs and Wages, or User Permissions to:
1) their own account at another location
2) another user's account at another location
Permissions Hierarchy -
Multi-location restaurants must have at least one "super user" at the corporate level that has access to all Toast permissions. This access is granted by a Toast employee. The "super user" should then choose a minimum of one manager user at each individual location that also has access to all permissions.
However, the permissions granted to the manager user at the individual locations are still to the super user's discretion. For example, the super user may not want a manager user to have access to certain Admin Permissions such as Financial Accounts or Franchisee Fees.
In order to make changes to a specific permission for another user, the user making the change must also have access to that permission.
To make changes to a specific permission for a user at another location, the user making the change must have the same permission granted to them at their original location AND at the location where the user's permission needs to be changed.
- Example: A user has the ability to Void Items / Orders at Location A but not at Location B.
- This user will only have the ability to grant other users access to the Void Items / Orders permission at Location A.
- If a user has the ability to Void Items / Orders at Location A, Location B, and Location C, then the user can grant the Void Items / Orders permissions to another user at all three locations.
Employee Information - The ability to edit a user's basic information (including contact information, password, and passcode) is based off of the Employee Info permission.
In order for a user to make changes to their own employee information OR to another user's employee information, the user making the changes must have the Employee Info permission granted to them.
To make changes to a user's employee information at another location, the user making the change must have the Employee Info permission granted to them at their original location AND at the location where the user's employee information needs to be changed.
Jobs and Wages - The ability to add or remove job roles from an employee is based off of the Employee Jobs & Wages permission and also on the permissions within the job role.
Requirements to add or remove a job role from a user at another location:
- The user adding/removing editing the job role must have all of the permissions that are required of the job role.
- Example: In order for User A to assign the Key Employee role to User B at User B's location, User A must have access to all of the permissions that are required within that job role.


How To Quit A Function In Python
When working with Python functions, there are times when you want to exit or quit a function before it fully completes its execution. This blog post will explain different ways to quit a function using Python, including the return statement, the sys.exit() method, and the raise statement with a custom exception.
1. Using the return Statement
The most common way to quit a function in Python is by using the return statement. When the return statement is executed, the function immediately exits, and any code following the return statement will not be executed.
Let's look at an example:
def my_function(num):
 if num < 0:
 print("Negative number. Exiting the function.")
 return
 result = num * 2
 print("The result is:", result)
my_function(-3)
my_function(5)
In this example, the function my_function checks if the input number is negative. If it is, the function prints a message and quits using the return statement before calculating the result. In this case, only the positive number (5) is processed, and its result is printed.
2. Using sys.exit()
Another way to quit a function in Python is by using the sys.exit() method. This method exits the entire Python program, not just the function. To use sys.exit(), you need to import the sys module first.
Note that sys.exit() should be used with caution, as it stops the entire program, not just the function from which it is called.
Here's an example:
import sys
def my_function(num):
 if num < 0:
 print("Negative number. Exiting the program.")
 sys.exit()
 result = num * 2
 print("The result is:", result)
my_function(-3)
my_function(5)
In this example, when the negative number is encountered, the sys.exit() method is called, and the entire program is terminated. The second function call with the positive number is never executed.
3. Raising a Custom Exception
Another approach to quit a function is by raising a custom exception. This method allows you to handle specific cases in your code more gracefully and provides more information about the reason for quitting the function.
Here's an example:
class NegativeNumberError(Exception):
 pass
def my_function(num):
 if num < 0:
 raise NegativeNumberError("Negative number encountered. Quitting the function.")
 result = num * 2
 print("The result is:", result)
try:
 my_function(-3)
except NegativeNumberError as e:
 print(e)
my_function(5)
In this example, we define a custom exception called NegativeNumberError and raise it when a negative number is encountered. Then, we wrap the function call in a try and except block to catch the custom exception and print its message.
In conclusion, there are several ways to quit a function in Python, including the return statement, the sys.exit() method, and raising a custom exception. The method you choose depends on your specific use case and requirements.

We observe two areas differences.
-Half exposed to sunlight directly have a growth of algae (zone green). In the water see bubbles of oxygen produced by algae, too there are a zone of glucose in the superfice.
-Other half with exposition sunlight indirect there isn't green zone but the black zone caused by the sulfurous precipitated is more expensive.

Here at RedRabbit, we know exactly how time-consuming and tedious maintenance management can be. That's why we provide you with the tools to easily organise and track each maintenance ticket from logged to completed.
Dealing with maintenance requires a lot of communication to keep all stakeholders informed. With our maintenance dashboards, you can easily track what has been done on any ticket and have all your communication and documentation in one place.
Residential Property Maintenance can originate from the following sources:
 - Inspections
 - Issue reported by the Tenant
 - Preventive maintenance initiated by the Landlord
Each of the above maintenance events will require:
 - Consultation with the Landlord
 - Quotes for work to be done
 - Tasking of Contractors to do the agreed to Maintenance
 - Keeping all parties informed
 - Quality control to ensure that the job has been done properly
 - Managing of the workflow from start to finish ensuring closure on every issue
In most cases the Agent will act on behalf of the Landlord with the Landlord only being involved at certain stages of the process. Since this might differ from Landlord to Landlord, it is extremely important to calibrate and agree with the landlord on how the process will work and where the Landlord would want to be involved. Specifically the following needs to be agreed to:
 - Basic process workflow when a new issue needs to be managed
 - The types of maintenance that will require a quote vs just permission to attend on a call out basis.
 - The number of quotes that the Landlord would require.
 - The discretionary amount that the agent can spend to deal with emergency situations where he cannot get hold of the Landlord within a reasonable amount of time.
 - How quality control will be handled
 - How payment for work will be done (direct by the landlord or paid from the rent)
Dealing with Maintenance requires lots of communication to keep all stakeholders informed and it is extremely important to have a system in place that will make it easy to communicate via Email and / or SMS. Typical communication that might be required include the following:
 - Letting Landlords and Tenants know that a new issue has been logged
 - Letting Contractors know that a job card has been issued for their attention
 - Letting Tenants know when a Contractor has been tasked to attend to an Issue
 - Asking for quality feedback after receipt of confirmation from a Contractor that a job has been completed.
 - Keeping Landlords and Tenants updated on progress for larger jobs or where there are delays.
A good system will allow you to use templates to avoid having to retype the same messages over and over again. In addition Email threads related to the same job should preferably be saved in an email repository that will make it easy to see all related email with the click of a button.
From time to time, certain difficult maintenance situations will require special attention and it is always a good idea to discuss these upfront with the Landlord and how you intend dealing with them. Examples of these include:
Water Leaks – Slow leaks might not be detected above ground until the Landlord is confronted by a huge water account. This would then probably require leak detection to determine the exact location of the leak before it can be repaired. If the leak are on the municipal side of the water connection to the property, it might require a call to the municipality to deal with the issue. High water readings might also be caused by faulty water meters. This will require meter testing by the municipality. They would normally require you to pay upfront for the testing and will refund you if it turns out that the water meter is faulty. Dealing with these kinds of leaks is very frustrating and the cost involved when having to do leak detection or meter testing.
Process Tips when you receive a high water account and suspect a water leak:
 1. Close all water outlets on the property.
 2. Take a water meter reading.
 3. Wait an hour and take another meter reading. If there has been any usage even with all outlets closed, you have a water leak or defective water meter.
 4. Inspect your property above ground looking specifically for obvious signs of a water leak. If any of these are present, a concealed water pipe could be the source of the problem and you will need to get a plumber involved to locate and fix the leak.
 1. Wet areas above ground
 2. Damp and Paint peeling on walls
 3. Damp and stains on ceilings
 5. If after following the above process, there is still no obvious sign of where the problem is, you might have to get a Leak Detection company involved. They have specialised equipment that allows them to do a pressure test to locate the specific location of the leak.
 6. If there are still no obvious leaks, you might be dealing with a defective water meter and you will then have to log a call with the municipality to test the meter.
Blocked Drains -Traditionally blocked drains are the Tenant's responsibility with the following two exceptions:
 - If it can be proven within an agreed to grace period from taking occupation that the drain has been blocked when the tenant moved in
 - If it can be proven that the blocked drain is caused by a structural problem such as a pipe collapse or tree roots penetrating a pipe.
In order to reduce the emotional response when encountering the effects of a blocked drain, it will serve you well to implement the following countermeasures pro-actively:
 - Ensure that your Lease includes a clause stating what the grace period is for reporting blocked drains after which it should be the Tenant's responsibility.
 - Include as part of the in-going inspection that all toilets should be flushed, baths, basins and showers tested to see if the water runs away freely.
 - Specifically check for large damp areas outside that might point to outside drain problems.
Break-ins – Any break-in is an emotional issue and since it involves blatant intrusion into a tenant's private space, you can expect that questions will be asked about the general safety of the property. If the tenant does not have short term insurance, it will be an even bigger issue since it will now involve money.
In order to be prepared should this happen to you, you can consider the following:
 1. Identify security related issues and shortcomings upfront when you list the property and advise the Landlord on how to make the Property as secure as possible by adding burglar bars, security gates, fencing, alarm systems, etc.
 2. Ensure that your Lease contains a specific clause stipulating that the Tenant is responsible for his / her own short term insurance.
 3. Have an emergency number and process available that can see the Tenant over in terms of ensuring their safety until the necessary maintenance has been done to fix broken doors and windows.
Leaking Roofs – This is one of the most problematic issues since it is so unpredictable. A roof might not leak for many years and then suddenly the wind blows from a unique direction and with enough force to penetrate and expose a weakness. Many tenants can be very unreasonable when it comes to roof leaks and might demand that it be fixed immediately. The problem is that roof leaks can only be fixed reliably when the roof is dry.
You can prepare for this by considering the following:
 1. Make a point to explain the issues associated with roof leaks to the Landlord and specifically ask about potential roof leaks and if possible, get them fixed before the tenant takes occupation.
 2. Ensure that the Tenant has short term insurance and that any such sort term insurance covers resultant water damage from leaking roofs, etc.
 3. When a roof leak is reported, explain to the tenant that it can only be fixed when the roof had time to dry out. Ask the tenant to temporarily move furniture that might be affected in order to avoid unnecessary resultant damage.
 4. Make sure that you have a reliable Contractor who specialises in Leaking Roofs and that you understand the process. There is nothing more frustrating having to deal with the same leak over and over again as a result of an incompetent contractor.
Wear and Tear Issues – these issues mostly relate to the upkeep of the basic structure and involves the walls, roof structure and ceilings, window and door frames, etc. If this kind of maintenance is not done, it can lead to huge costs and might even require complete replacement. In addition, if the structure is not good, you might have to be satisfied with a reduction in rent.
Wear and tear is the change or damage to the condition of a property that happens as a result of everyday use. It is not caused by abuse or neglect. Typical examples include:
 - Some scratches on a wooden floor
 - Color of carpet of hardwood fading due to sunlight exposure
 - Dirty Grout
 - Deterioration of paint or varnish condition on walls, windows and doors as a result of exposure to the elements
 - Cracked tiles resulting from structural movement
You should proactively avoid this at all cost. Considering the following:
 - Explain to the Landlord upfront what constitutes wear and tear.
 - Give the Landlord a condition report of times that might require regular preventive maintenance together with a 5 year schedule of when what needs to be done to keep the property (his asset) in tip top condition and worthy of the rental return he expects.
 - Provide the Landlord with a saving option whereby a small amount is taken from the rent every month and put in a savings account for the Landlord in order to provide funding for preventive maintenance.
Issues involving a Sectional Title Scheme
Many rental properties form part of a sectional title scheme which means that the Landlord is no longer responsible for all the maintenance issues associated with the Property.

Landmarking is a novel approach to describing tasks in meta-learning. Previous approaches to meta-learning mostly considered only statistics-inspired measures of the data as a source for the definition of meta-attributes. Contrary to such approaches, landmarking tries to determine the location of a specific learning problem in the space of all learning problems by directly measuring the performance of some simple and efficient learning algorithms themselves. In the experiments reported we show how such a use of landmark values can help to distinguish between areas of the learning space favouring different learners. Experiments, both with artificial and real-world databases, show that landmarking selects, with moderate but reasonable level of success, the best performing of a set of learning algorithms.

Staphorst alleyway residents caught in postal delivery bind
Tags: Excerpts from the Windmill
STAPHORST – Residents of rare alleyways in the tourism weary but very picturesque Dutch town of Staphorst are battling the one-size-fits-all bureaucratic attitude of their postal services and the heritage protection rules of their municipal government. Through the centuries, local residents, usually farming families, kept adding traditional farmsteads on dead-end alleyways as the next generation needed a place of their own. These structures were buildings with the farmer's family and livestock all under one roof (a traditional and common Dutch practice). The alleyways and the linear 'peat colony' layout of the town were all given protected heritage status under the so-called Belvedere legislation, which combines cultural historical aspects with space concerns. The postal services want the residents to pick up the mail from proposed mailboxes on the main road, which the residents are resisting. A high court sided with the postal services but now the municipality opposes the idea of modern mailboxes since these are seen to ruin the quaint appearance of the protected town site. The residents say they are not impressed with the help they received from their municipal officials.

Hiawatha Maintenance Facility wins 2012 EcoBLEND Award
The City of Minneapolis Hiawatha Maintenance Facility received the 2012 EcoBLEND Award for its commitment to ecologically sound practices while using design to be a good neighbor. The EcoBLEND Award honors builders, architects and homeowners for eco-friendly design and sustainable building practices in new and remodeled projects in Minneapolis.
The judges were impressed with the commitment to ecologically sound practices while being sensitive to the neighborhood in their approach to the building's design. Judges applauded the massive recycling (including benches made of shredded money), the focus on repurposing items (including using onsite wood) rather than simply landfilling the demolition waste and the building's approach to the geothermal and the heat sink materials that were used
This standard of building reflects the City policy requiring new or major renovations of municipal buildings to meet Leadership in Energy and Environment Design (LEED) silver level requirements. LEED creates a set of standards that call for buildings to be constructed in ways that have been proven to reduce the consumption of energy and other natural resources, and improve building performance, cost efficiency and building longevity.
The 2009-2010 project transformed an unsightly, partly historic public-works facility into an attractive and environmentally-responsible maintenance complex. The Hiawatha Maintenance facility has LEED Platinum certification, the highest certification awarded by LEED. The award-winning facility was constructed on a site that used to house a complex of 18 Public Works buildings, some dating back to the turn of the 20th century. More than 1,300 tons of construction waste were diverted from a landfill through recycling. The costs associated with the energy-saving features will pay for themselves in four to six years, and did not cost more than simply building to code. The energy-saving strategies result in approximately $112,998 per year savings. Find features, details and a photo gallery at _URL_
ECoBLEND is sponsored by Linden Hills Power and Light and is part of the citywide B.L.E.N.D. award, which encourages builders, architects and homeowners to blend newly built or remodeled homes and businesses into the fabric of Minneapolis neighborhoods.

Top 5 Reasons to Choose Popular Piercings
Navel piercingThere are some very popular piercing types that many people choose for themselves. Piercings such as earlobe, navel, eyebrow, tongue, nostril or labret piercings are among the most common body piercings in the world.
Since they are so popular, it means that there are always many people who have the same piercing. It may make these piercings more ordinary and less unique than some other piercing types.
However, common piercings have some important advantages so there are many reasons to choose popular piercings for yourself.
Here are some of the most important reasons to choose popular piercings:
 1. Experienced Piercers
If a piercing is popular, then it means there are many piercers who know how to perform it and who have at least some experience with this piercing type. Remember, you should not look for a … read more


"}
Each template can have multiple tr_context statements. The default context that is set with this construct is valid until the next one is encountered.
tr
The tr construct defines a translatable string, the simplest form of this construct is:
{tr "String to translate"}
This will only work however, if there is a default context set with tr_context. In case there is none set, you have to specify it yourself with the "context" parameter. The following two templates are equivalent:
{tr_context "admin/forget_password"} {tr "String to translate"}
and:
{tr "String to translate" context "admin/forget_password"}
When a translator translates a text, it is sometimes useful to have slightly more information than just the context and the string itself. The tr construct therefore allows to add a comment to the translatable string with the "comment" parameter. This has no effect on how the tr construct is interpreted however. An example:
{tr "Login" context "user/login" comment "Text before login input box"}
In many occasions, the translatable strings allow positional or named parameters to allow for changing the order of arguments. For example the English string "Search for 'appelmoes' returned 3 matches" can be translated in Dutch as: "Er zijn 3 items gevonden bij het zoeken naar 'appelmoes'". A simple concatenation mechanism of multiple translatable strings would no longer work. The tr construct supports parameterized strings in two different ways: with numerical replacement identifiers (such as %1 and %2) and with associative identifiers (such as %search_string and %matches). The following example illustrates how this is done in the simplest possible way:
{tr "Search for '%1' returned '%2' matches" vars 'appelmoes', 3}
If no key is specified for variables, like in the above example, they are automatically given numbers, starting by 1. It is also possible to add specific positions to variables, like:
{tr "Search for '%1' returned '%2' matches" vars 2 => 'appelmoes', 1 => 3}
This is perhaps not so useful for positional parameters like here, but it is necessary for named parameters as illustrated in the example here:
{tr "Search for '%what' returned '%matchcount' matches" vars 'what' => 'appelmoes', 'matchcount' => 3}
It is of course also possible to mix those two cases:
{tr "Search for '%1' returned '%matchcount' matches" vars 'matchcount' => 3, 'appelmoes'}
or:
{tr "Search for '%1' returned '%matchcount' matches" vars 'appelmoes', 'matchcount' => 3}
Variables without any key, are always given positional identifiers in sequential order. When doing so, variables with a named key are ignored, while variables with a numerical key reset the next number in the auto-numbering sequence to the number of the key. The following example shows that:
{tr "%1 %2 %3 %4 context "test" vars 3 => 'three', 'four', 1 => 'one', 'two'}
For information on how to setup translations for your templates, please refer to the section Translations.
Extensions
This section explains how you can extend your Template language. Extending the Template language gives you the opportunity to add more application specific functionality. Some examples of Template language extensions are:
Currently, there are two ways of adding custom functionality to the template. The methods are named: custom blocks and custom functions. Together we call them custom extensions.
First, we'll explain how to create a custom block. With the knowledge of these custom blocks, we explain - much shorter - the custom functions.
Custom blocks
Custom blocks are extra functionality that could be used inside the template language. These blocks are implemented in PHP. The next section explains how an custom block can be used. The sections thereafter discuss how to add a new custom block.
Custom blocks in the Template language
Custom blocks add specific behavior to the Template language. The most basic structure of a custom block - without any parameters - is:
'{' <name> '}'
The block starts and ends with curly braces. The <name> identifies the custom block. Optionally, a custom block has also a closing block:
'{' '/' <name> '}'
The name must be the same as the start block, but starts with a forward slash ('/'). The text between the open and close tag is considered as input data. Whether a custom block should have a close tag is up to the developer.
The next example demonstrates a custom block with an open and close tag that capitalizes the text in between:
{capitalize} Guybrush Threepwood. {/capitalize}
Another example that uses a custom block without a close tag:
{capitalize "Guybrush Threepwood."}
Whether or not a custom block has a close tag, it handles the parameters the same. The structure of a custom block is as follows:
'{' block_name [start_expression] [ <param_name> ['='] <value> ... ] '}'
Basically, it describes that a custom block can have:
Some example blocks that use parameters:
{link "eZ systems" to "_URL_"} {table border=true bgcolor="red"} {debug} {calculate 5 plus 5} {join array( 'Hello', "world" ) with "_"} {header style="bold"} Hello world {/header}
Note that the values used in the examples are just ordinary expressions. Therefore it is possible to write:
{link "eZ" . " systems" to 'http'. "://" . "ez.no"} {calculate 2 + 3 plus 1 * 2 + 3}
Again, the optional and required parameters are up to the developer.
Adding a custom block
New custom blocks are added to the Template engine with the ezcTemplateConfiguration::addExtension() method. This method expects the class name which implements the new custom block. The next example adds a custom block to the Template engine which is implemented in MyClass:
$config = ezcTemplateConfiguration::getInstance(); $config->addExtension( "MyClass" );
The custom block class should implement the ezcTemplateCustomBlock interface. This interface has only one method getCustomBlockDefinition(). The class implementing this method should return an ezcTemplateCustomBlockDefinition object from a given block name, if possible.
Custom block definition
The custom block definition describes how the Template engine should interpret the custom block. The information is provided by returning an instance of the ezcTemplateCustomBlockDefinition:
class ezcTemplateCustomBlockDefinition extends ezcTemplateCustomExtension { public $class; public $method; public $hasCloseTag; public $startExpressionName; public $optionalParameters = array(); public $requiredParameters = array(); public $isStatic; }
The member variables that should be set in this class are:
The following custom block creates a hyper-link from a name and an URL:
{link "name" to "url" [title "title"]}
This custom block has a:
Except for the class and the method name the CustomBlockDefinition should look like:
$def = new ezcTemplateCustomBlockDefinition; $def->class = "MyLink"; $def->method = "linkMethod"; $def->hasCloseTag = false; $def->startExpressionName = "from"; $def->optionalParameters = array( "title" ); $def->requiredParameters = array( "from", "to" );
The CB definition should be made available to the Template engine via a class implementing the ezcTemplateCustomBlock interface:
interface ezcTemplateCustomBlock { public static function getCustomBlockDefinition( $name ); }
The class implementing the getCustomBlockDefinition() method should return an ezcTemplateCustomBlockDefinition for the given block name $name. The next code demonstrates a class that implements the interface:
class MyLink implements ezcTemplateCustomBlock { public static function getCustomBlockDefinition( $name ) { switch ($name ) { case "link": $def = new ezcTemplateCustomBlockDefinition; $def->class = "MyLink"; // // Create definition // return $def; } return false; } }
Implementing the custom block
In the CB definition is specified which class and what method should produce the custom block output. A typical implementation to create a hyper-link would be:
public static function link( $parameters ) { $title = ""; if( isset( $

ALBUQUERQUE, N.M. - New Mexico State University Extension specialists will provide the latest information on raising livestock, vegetables, and fruit and berries, as well as ways to market agricultural products, during the annual New Mexico Pueblo and Community Agriculture Conference.
The conference will be from 7:30 a.m. to 4:30 p.m. Wednesday and Thursday, April 6-7, at the Bernalillo County 4-H Building, 1510 Menaul NW, Albuquerque.
"This agricultural conference is the result of direct input and direction from our pueblo producers," said Edmund Gomez, director of NMSU's Rural Agricultural Improvement and Public Affairs Project. "With the partnership of NMSU Cooperative Extension Service and several United States Department of Agriculture agencies, we will provide research-based information that is timely and appropriate to the Pueblo agricultural needs."
A highlight the conference is the involvement of youth, including Lincoln Calabaza of Kewa Pueblo (formerly known as Santo Domingo Pueblo), who is the winner of the national 2010 Native Women and Youth in Agriculture youth essay competition. He was honored at the Intertribal Agriculture Council and Indian Nations Conservation Alliance Agriculture Symposium at Las Vegas, Nevada, in December.
A student at Santa Fe Indian School, Calabaza will present his essay titled "Do Your Reservation Farmers and Ranchers Feed You?" during the luncheon.
"We are also very pleased that youth from Kewa Pueblo Elementary School, who have been involved in a hoop house project, and students from Santa Fe Indian School have registered to attend this conference, thus showing promise from another generation of farmers and ranchers on our native pueblos," Gomez said.
Jon Boren, assistant dean of the College of Agricultural, Consumer and Environmental Sciences and director of the NMSU Cooperative Extension Service, will open the conference with greetings on Wednesday. Invocation will be given by Percy Reano of Santo Domingo Pueblo on Wednesday and Anthony Dorame, Jr., of Tesuque Pueblo on Thursday.
The first day's morning sessions include integrated pest management with vegetable crops, hoop house production, building good soils, berry and fruit production, and market development for fruits and vegetables. During the afternoon, there will be two tracks. Track one will address tractor maintenance, implement selection and custom farming. Track two will include rules and regulations for food processing and a session on food preservation.
On the second day, representatives from the USDA Farm Service Agency, Natural Resource Conservation Service, Rural Development and National Agricultural Statistics Service will discuss how their programs can help the producers.
Other sessions will address controlling birds, rodents and predators; beef cattle marketing; current issues of hantavirus; sheep production and marketing; and horse care. Two sessions will feature John Wenzel, NMSU Extension veterinarian, discussing bull selection and giving an overview of bovine trichomoniasis.
Registration prior to April 1 is $10 per day. After April 1, registration is $15 for a single day or $25 for both days. Lunch is included. The first 100 people to register will have their fees waived. Registration for the conference may be done by calling August Archuleta at _PHONE_, or by mailing name, address, phone and e-mail information with registration fee to Archuleta at NMSU CES/RAIPAP, P.O. Box 159, Alcalde, NM 87511.

NASA's Destination Station Exhibit Opens In Mesa, Arizona
HOUSTON, Dec. 21, 2012 /PRNewswire-USNewswire/ -- Arizonans can get a sense of what spaceflight is like starting today, as NASA's Destination Station exhibit opens at the Arizona Museum of Natural History in Mesa. The interactive exhibit reveals the inside of America's orbiting laboratory while educating visitors about the vast array of science and research being done in low-Earth orbit.
"This exhibit is a magnificent way for children, especially, to be able to imagine what it is like for astronauts living in space," said Kathy Eastman of the museum. "It brings to life what many children dream about when they look at the stars."
The exhibit opening is a precursor to more NASA activities coming in 2013. Destination Station is NASA's International Space Station Program national awareness campaign, promoting station research and opportunities, educating communities about the people living and working on the station, and communicating the real and potential benefits for our everyday lives. The exhibit is free with admission to the museum. NASA will be sponsoring many activities that will be open to the public at various locations in the Phoenix and Tucson areas Feb. 21 through March 3.
The space station is a multinational research facility and the largest spacecraft ever built. It is an official U.S. National Laboratory where astronauts and scientists from around the world conduct experiments in fundamental life, physical, Earth and space science, as well as human health, technologies for space exploration and the improvement of life on Earth.

Tech Tip: testing DC armatures
DC armatures are the most time-consuming components to test, but they are also the easiest.
DC armatures are the most time-consuming components to test, but they are also the easiest. There are three basic methods that can be used.
With trending, all measurements are used; however, a bar-to-bar impedance measurement is used for assembled and disassembled testing.
When testing an assembled DC armature, the best method is to perform a bar-to-bar test using the motor brushes. If the motor has two brushes, they don't need to be raised. If there are four or more sets of brushes, all but two sets 90 degrees from each other need to be raised, which takes them out of the testing circuit. Good contact is maintained by ensuring more than 90% of the brush is in contact with the commutator bars, which should be clean.
Once set, mark the position of one bar on the commutator, then bring the bar to a position where it is just under the leading edge of one of the brushes. In the assembled test, you will probably be covering at least one and a half bars with the brush. Perform an impedance test, mark down the reading, and move the armature so that the leading edge of the brush is over the next commutator bar. Take the next impedance reading and continue until each bar has been tested.
A good result will show a consistent pattern, while an inconsistent pattern will identify a poor armature.
In disassembled bar-to-bar testing, the tester will use an armature fixture or test leads to connect from bar-to-bar. The spacing between each impedance reading should be constant and about 90 to 180 degrees from each other. The first bar should be marked and testing should then be continued until one leg of the testing fixture or test lead has made it 360 degrees around the commutator. Mark the impedance for each bar-to-bar test then look to ensure there is a consistent pattern.

Microtunneling (also spelt microtunnelling) is currently the most accurate pipeline installation method available to the civil construction industry. Line and grade tolerances of +/- 25mm/one inch are the microtunneling industry standard. UEA specialises in Pilot Tube Microtunneling using a Laser Guided Boring Machine (GBM).
Pilot Tube Microtunneling
The pilot tube microtunneling system can be used on its own or in conjunction with an auger boring system.
Pilot tube microtunneling is an on grade pilot hole system capable of installing pipes up to 1200mm in diameter and, subject to diameter and ground type, up to 120m in length. The technique is predominantly used to install casing pipes on grade.
When the pilot tube is being installed it displaces the soil as it is thrust forward and must be used in displaceable soil. This system is most suitable for ground condition up to 10Mpa.
UEA Trenchless offers the following pilot tube microtunneling services and capabilities:
- Carrier pipe directly installed up to 600mm diameter
- Steel casing sleeves installed up to 1500mm
- Installation distances up to 120m (subject to diameter and ground type)
- All utilities catered for
- Civil works associated with the tunneling installation
- On grade boring capability

Y3 Attract or Repel (black and White)?
Pupils investigate magnets and learn that they have two ends that we call poles. One end is the magnetic north pole (N) and the other is the magnetic south pole (S). Pupils investigate what happens when these poles are positioned together and learn that magnets, depending on their arrangement of poles, can either attract or repel each other.
Learning Objectives:
 - POS - notice that some forces need contact between two objects, but magnetic forces can act at a distance; observe how magnets attract or repel each other and attract some materials and not others; describe magnets as having two poles; predict whether two magnets will attract or repel each other, depending on which poles are facing
 - NaG - pupils should look for patterns in the way that magnets behave in relation to each other and what might affect this
 - WS - pupils should set up simple practical enquiries, comparative and fair tests; use straightforward scientific evidence to answer questions or to support their findings; gather, record, classify and present data in a variety of ways to help in answering questions

How Many Monks?
No comments :
how many monks riddle
There's a monastry of fifty monks that have taken a vow of silence. They go through the same routine every day. They wake up, pray. They go to lunch, their only meal of the day, were they all sit round a big circular table, and eat a simple meal. Then they go back to their rooms and pray. Then they fall asleep.
One day, the head monk of the area comes to visit. He's a bit different - he's allowed to talk and has a life outside the monastry. He tells them that there is currently a plague ravaging the land. People everywhere are dying. The disease manifests itself as red blotches on the forehead. The blotches are the only manifestation of the disease for three months, whereupon the next stage starts, a horribly painful death.
The head monk tells them that at least one of their midst will have the disease, probably more. Anybody with the disease should kill themselves, to save all of the pain and suffering. By killing themselves, they will restrict the movement of the disease, and will go to heaven. Anybody with the disease will show the first symptoms within a month. The chief monk then leaves. He returns two months later, to find that all of the infected monks have killed themselves, and they all did it on the same day.
Bear in mind the following:
 - They have no mirrors or any other way of seeing themselves
 - The blotches appear only on the forehead and cannot be seen by the monk
 - Infected monks feel no different - the only manifestation of the first part of the disease are the blotches.
 - The monks cannot talk to each other or in any other way communicate.
 - Any monks with the disease will display the blotches within a month of the head monk leaving.
 - At least one monk definitely has the disease.
 - The monks only see each other once per day, at lunch, when they are all sat round the round table.
 - These monks are brighter than the average monk....
How did they know whether or not they were infected and why did they all kill themselves on the same day?
How Many Monks? Puzzle Solution
The way they work this out and the reason it happens on the same day is as follows. It is important to note that not only are the monks intelligent but they all know all their fellow monks are as well.
Start with one monk:
He knows he is the only one who can have the disease so he kills himself on
day 1.
Then two monks:
They know that either one of them has the disease or both do. If monk1
doesn't see the mark of the disease on monk2 then he will realise that he
must have it so will kill himself. If he sees the mark then he knows that
monk2 will following the same reasoning and kill himself. If the next day
the other monk is still alive then he realises that the other monk must have
seen the mark on him and so they both have the disease and he must kill
himself. Both follow the same reasoning and kill themselves on day 2.
Three monks:
If only one of the monks has the disease he will see no mark on the other
two and so diagnose himself. He will kill himself on day one. If two monks
have the disease then they will each see one monk with the mark and one
without. When they see each other again the next day they will deduce that
the monk they see with the mark would only not have killed himself if he
could see someone else with the mark. They know it is not the third monk so
it must be them. Both diseased monks follow the same reasoning and kill
themselves on day two. If all three monks have the disease then they are all
in the same position as the healthy monk in looking on in the previous
example. Each of them can see two diseased men. When they haven't both
killed themselves on day two there can be only one reason - the viewing monk
must have the mark as well. All taking the same reasoning they all kill
themselves on day three.
And so on...
N monks all with the disease will all kill themselves on day N.

A previously unknown population of vampire moths has been found in Siberia. And in a twist worthy of a Halloween horror movie, entomologists say the bloodsuckers may have evolved from a purely fruit-eating species.
Only slight variations in wing patterns distinguish the Russian population from a widely distributed moth species, Calyptra thalictri, in central and southern Europe known to feed only on fruit.
When the Russian moths were experimentally offered human hands this summer, the insects drilled their hook-and-barb-lined tongues under the skin and sucked blood.
Entomologist Jennifer Zaspel at the University of Florida in Gainesville said the discovery suggests the moth population could be on an "evolutionary trajectory" away from other C. thalictri populations. This is the second population of vampire moths Zaspel and her team have found. They discovered the first in Russia in 2006.
Next January, she will compare the Russian population's DNA to that of other populations and other species to confirm her suspicions.
"Based on geography, based on behavior, and based on a phenotypic variation we saw in the wing pattern, we can speculate that this represents something different, something new," Zaspel said.
"But it is really difficult to say without knowing genetic differences between individuals in that population, and among individuals from other populations, how different this group is going to be."
(Zaspel's research is funded in part by a grant from the National Geographic Society's Committee for Research and Exploration. National Geographic owns National Geographic News.)
If it turns out that Zaspel has indeed caught a fruit-eating moth evolving blood-feeding behavior, it could provide clues as to how some moths develop a taste for blood.

predictNLS (Part 2, Taylor approximation): confidence intervals for 'nls' models
Initial Remark: Reload this page if formulas don't display well!
As promised, here is the second part on how to obtain confidence intervals for fitted values obtained from nonlinear regression via nls or nlsLM (package 'minpack.lm').
I covered a Monte Carlo approach in _URL_ but here we will take a different approach: First- and second-order Taylor approximation around f(x): f(x) \approx f(a)+\frac {f'(a)}{1!} (x-a)+ \frac{f''(a)}{2!} (x-a)^2.
Using Taylor approximation for calculating confidence intervals is a matter of propagating the uncertainties of the parameter estimates obtained from vcov(model) to the fitted value. When using first-order Taylor approximation, this is also known as the "Delta method". Those familiar with error propagation will know the formula
\displaystyle \sum_{i=1}^2 \rm{j_i}^2 \sigma_i^2 + 2\sum_{i=1\atop i \neq k}^n\sum_{k=1\atop k \neq i}^n \rm{j_i j_k} \sigma_{ik}.
Heavily underused is the matrix notation of the famous formula above, for which a good derivation can be found at _URL_
\sigma_y^2 = \nabla_x\mathbf{C}_x\nabla_x^T,
where \nabla_x is the gradient vector of first-order partial derivatives and \mathbf{C}_x is the variance-covariance matrix. This formula corresponds to the first-order Taylor approximation. Now the problem with first-order approximations is that they assume linearity around f(x). Using the "Delta method" for nonlinear confidence intervals in R has been discussed in _URL_ or _URL_
For highly nonlinear functions we need (at least) a second-order polynomial around f(x) to realistically estimate the surrounding interval (red is linear approximation, blue is second-order polynomial on a sine function around x = 5):
Taylor
Interestingly, there are also matrix-like notations for the second-order mean and variance in the literature (see _URL_ or _URL_
Second-order mean: \rm{E}[y] = f(\bar{x}_i) + \frac{1}{2}\rm{tr}(\mathbf{H}_{xx}\mathbf{C}_x).
Second-order variance: \sigma_y^2 = \nabla_x\mathbf{C}_x\nabla_x^T + \frac{1}{2}\rm{tr}(\mathbf{H}_{xx}\mathbf{C}_x\mathbf{H}_{xx}\mathbf{C}_x),
where \mathbf{H}_{xx} is the Hessian matrix of second-order partial derivatives and tr(\cdot) is the matrix trace (sum of diagonals).
Enough theory, for wrapping this all up we need three utility functions:
1) numGrad for calculating numerical first-order partial derivatives.
numGrad <- function(expr, envir = .GlobalEnv)
{
 f0 <- eval(expr, envir)
 vars <- all.vars(expr)
 p <- length(vars)
 x <- sapply(vars, function(a) get(a, envir))
 eps <- 1e-04
 d <- 0.1
 r <- 4
 v <- 2
 zero.tol <- sqrt(.Machine$_URL_
 h0 <- abs(d * x) + eps * (abs(x) < zero.tol)
 D <- matrix(0, length(f0), p)
 Daprox <- matrix(0, length(f0), r)
 for (i in 1:p) {
 h <- h0
 for (k in 1:r) {
 x1 <- x2 <- x
 x1 <- x1 + (i == (1:p)) * h
 f1 <- eval(expr, as.list(x1))
 x2 <- x2 - (i == (1:p)) * h
 f2 <- eval(expr, envir = as.list(x2))
 Daprox[, k] <- (f1 - f2)/(2 * h[i])
 h <- h/v
 }
 for (m in 1:(r - 1)) for (k in 1:(r - m)) {
 Daprox[, k] <- (Daprox[, k + 1] * (4^m) - Daprox[, k])/(4^m - 1)
 }
 D[, i] <- Daprox[, 1]
 }
 return(D)
}
2) numHess for calculating numerical second-order partial derivatives.
numHess <- function(expr, envir = .GlobalEnv)
{
 f0 <- eval(expr, envir)
 vars <- all.vars(expr)
 p <- length(vars)
 x <- sapply(vars, function(a) get(a, envir))
 eps <- 1e-04
 d <- 0.1
 r <- 4
 v <- 2
 zero.tol <- sqrt(.Machine$_URL_
 h0 <- abs(d * x) + eps * (abs(x) < zero.tol)
 Daprox <- matrix(0, length(f0), r)
 Hdiag <- matrix(0, length(f0), p)
 Haprox <- matrix(0, length(f0), r)
 H <- matrix(NA, p, p)
 for (i in 1:p) {
 h <- h0
 for (k in 1:r) {
 x1 <- x2 <- x
 x1 <- x1 + (i == (1:p)) * h
 f1 <- eval(expr, as.list(x1))
 x2 <- x2 - (i == (1:p)) * h
 f2 <- eval(expr, envir = as.list(x2))
 Haprox[, k] <- (f1 - 2 * f0 + f2)/h[i]^2
 h <- h/v
 }
 for (m in 1:(r - 1)) for (k in 1:(r - m)) {
 Haprox[, k] <- (Haprox[, k + 1] * (4^m) - Haprox[, k])/(4^m - 1)
 }
 Hdiag[, i] <- Haprox[, 1]
 }
 for (i in 1:p) {
 for (j in 1:i) {
 if (i == j) {
 H[i, j] <- Hdiag[, i]
 }
 else {
 h <- h0
 for (k in 1:r) {
 x1 <- x2 <- x
 x1 <- x1 + (i == (1:p)) * h + (j == (1:p)) *
 h
 f1 <- eval(expr, as.list(x1))
 x2 <- x2 - (i == (1:p)) * h - (j == (1:p)) *
 h
 f2 <- eval(expr, envir = as.list(x2))
 Daprox[, k] <- (f1 - 2 * f0 + f2 - Hdiag[, i] * h[i]^2 - Hdiag[, j] * h[j]^2)/(2 * h[i] * h[j])
 h <- h/v
 }
 for (m in 1:(r - 1)) for (k in 1:(r - m)) {
 Daprox[, k] <- (Daprox[, k + 1] * (4^m) - Daprox[, k])/(4^m - 1)
 }
 H[i, j] <- H[j, i] <- Daprox[, 1]
 }
 }
 }
 return(H)
}
And a small function for the matrix trace:
tr <- function(mat) sum(diag(mat), na.rm = TRUE)
1) and 2) are modified versions of the genD function in the "numDeriv" package that can handle expressions.
Now we need the predictNLS function that wraps it all up:

v5: Incompatible Disk Selected
This article explains the reasons why you might see the error message "Incompatible Disk Selected" when attempting a Restore or Clone operation.
Notes:
 - This is only an issue with when the structure of the target disk for a restore or clone differs from the source. It does not concern disks used to store images / backup files.
 - There are no disks currently available that would cause this issue when connected directly (i.e. not via USB). However, some external disk enclosures are remapping the native disk structure to enable > 2TB disks to be used with Windows XP.
When restoring or cloning you may see the error message box below and be prevented from continuing with the operation:
The error indicates that the target disk has a larger sector size than the source or you are using a USB disk enclosure that is changing the reported sector size of the disk. This is not supported.
The table below shows compatible disks for the source and target of restore and clone operations:
 Source Sector Size
Target Sector Size
 Compatible
 512 or 512e 512 or 512e
 512 or 512e 4096 No
 4096 512 or 512e
 4096 4096

How do I check disk sector sizes?
1. Press the 'Windows' key, type 'System
Information' and press 'Enter'
2. In the Window that opens, expand 'Components' > 'Storage' and select 'Disks'. A list of all locally attached disk will be displayed in the right Window. The 'Bytes/Sector' field will display the sector size.
Note:
Disks with a physical sector size of 4096 Bytes that implement 512e will show 512
Note: If your PC uses "Intel Rapid Storage Technology" (RST) also known as "Intel Matrix Storage" then you may need to update the Intel Matrix/RST driver to the latest release when moving to a disk that supports Advanced Format 512eIntel RST Driver Download
What is a disk sector?
A sector is the smallest addressable block on a disk and until recently all disks had a sector size of 512 Bytes. With the advent of larger, multi Terabyte, disks the physical sector size has increased on some disks to 4096 Bytes. These are sometimes referred to as 4K sector disks. To overcome Windows compatibility issues the majority of disks use a technology called Advanced Format 512e. This enables 4K disks to emulate 512 Byte sector size disks by providing an emulated sector size of 512 Bytes.
So what's the problem?
The NTFS file system contains a data structure called the Master File Table (MFT). The MFT is critical to the file system and defines all the files and directories. The MFT contains 'records' and each record is 1024 Bytes (1K) long if the disk sector size is 512 Bytes. For a 512 Bytes per sector disk this equates to 2 sectors. If the entire file system is restored or cloned to a disk with a sector size of 4096 Bytes then each MFT record (at 1K) would be a quarter of a sector. Since a sector is the smallest amount data that can be read or written to a disk this means that NTFS cannot directly read it's own data! 4K Disks that support Advanced Format 512e do not have this problem as these disks permit directly accessing 512 Bytes of data.
Update for external USB enclosures...
We have identified that a number of recent external USB enclosures will 'fake' 4096 Bytes per sector disks and cause the error above. This happens regardless of the actual sector size of the attached disk and even if the disk supports 512e.
Why do they do this?
Normally disks with 512 Bytes per sector that are larger than 2TB would need to be initialized using the GUID Partition Table (GPT) format. Note that GPT disks are not supported by Windows XP, however, MBR disks are supported by all Windows Operating Systems, including Windows XP.
If the reported sector size is changed to 4096 Bytes then MBR disks can be as large as 16 Terabytes and still be accessible by Windows. So, by changing the reported disk sector size to 4096 Bytes for disks attached to the enclosure this enables all Windows PC's from XP onwards to be able to access disks greater then 2TB. If you are selling USB enclosures then this gives you a larger potential market and is a 'no-brainer' product feature.
Isn't this good?
Well yes, if the only purpose for the USB enclosure is to provide additional storage and you do not intend to take out the disk. But this is bad if you intend to clone to a disk in the enclosure and then use the cloned disk to boot your PC. It simply won't work. If you remove the disk from the enclosure then it cannot be read. This is because the sector size will change and the partition structures on the disk will be unreadable.
So what do I do?
If you receive the 'Incompatible Disk Selected' error shown above and you are using an external USB enclosure, then either try a different enclosure which doesn't change the reported disk sector size or directly attach the disk to a spare SATA port on your PC's motherboard. This will ensure that the disk manufacturer's drive geometry is reported correctly and may allow you to proceed with your clone or restore operation providing that the reported sector size is now compatible.

Stuffing Stuff"ing, n. 1. That which is used for filling anything; as, the stuffing of a saddle or cushion. [1913 Webster]
2. (Cookery) Any seasoning preparation used to stuff meat; especially, a composition of bread, condiments, spices, etc.; forcemeat; dressing. [1913 Webster]
3. A mixture of oil and tallow used in softening and dressing leather. [1913 Webster]
{Stuffing box}, a device for rendering a joint impervious where there is a hole through which a movable cylindrical body, as the paston rod of a steam engine, or the plunger of a pump, slides back and forth, or in which a shaft turns. It usually consists of a box or chamber, made by an enlargement of part of the hole, forming a space around the rod or shaft for containing packing which is compressed and made to fill the space closely by means of a sleeve, called the gland, which fits loosely around the rod, and is pressed upon the packing by bolts or other means.

Magnetic materials: a journey from finding north to an exciting printed future
The potential implications/applications of printing technologies are being recognized worldwide across different disciplines and industries. Printed magnetoactive smart materials, whose physical properties can be changed by the application of external magnetic fields, are an exclusive class of smart materials that are highly valuable due to their magnetically activated smart and/or multifunctional response. Such smart behavior allows, among others, high speed and low-cost wireless activation, fast response, and high controllability with no relevant limitations in design, shape, or dimensions. Nevertheless, the printing of magnetoactive materials is still in its infancy, and the design apparatus, the material set, and the fabrication procedures are far from their optimum features. Thus, this review presents the main concepts that allow interconnecting printing technologies with magnetoactive materials by discussing the advantages and disadvantages of this joint field, trying to highlight the scientific obstacles that still limit a wider application of these materials nowadays. Additionally, it discusses how these limitations could be overcome, together with an outlook of the remaining challenges in the emerging digitalization, Internet of Things, and Industry 4.0 paradigms. Finally, as magnetoactive materials will play a leading role in energy generation and management, the magnetic-based Green Deal is also addressed.

Assume that I have an Ecore-model containing a package and some classes that make reference to each other. If i create a "Dynamic Instance", Eclipse produces an XMI-file and I can instantiate some classes. Containment-relations are directly serialized to an XML-tree in the XMI (the children elements in the example). But if I instantiate references to elements that are already contained somewhere in the tree, the Editor writes Path-Expressions like in the following, for the currentChild attribute:
As far as I know this is not XPath, because:
 1. The "childrens" are elements not attributes and have not to be referenced via "@"
 2. XPath uses the e.g., elem[1] and not elem.1 to get e.g., the second elem of a list
What is it and where can I find a information on it? I already tried to browse the EMF pages/specs but could not find it.

It's an EMF Fragment Path. The Javadoc describes it like this:
String org.eclipse.emf.ecore.InternalEObject.eURIFragmentSegment(EStructuralFeature eFeature, EObject eObject) Returns the fragment segment that, when passed to eObjectForURIFragmentSegment, will resolve to the given object in this object's given feature.
The feature argument may be null in which case it will be deduced, if possible. The default result will be of the form:
The index is used only for many-valued features; it represents the position within the list.
Parameters: eFeature the feature relating the given object to this object, or null. eObject the object to be identified. Returns: the fragment segment that resolves to the given object in this object's given feature.

text: Raspberries contain flavonoid antioxidants whose relative concentrations may vary between the juice, pulp, and seed fractions. Oxygen radical absorbance capacity (ORAC), total anthocyanin content, and berry color were determined for six cultivars of primocane raspberries grown in a dry climate (Utah, USA). Significant ORAC differences were found between juice (18.4 ± 0.39 μmol TE/g), pulp (24.45 ± 0.43), and seeds (273.27 ± 11.15) with all Utah cultivars combined. A significantly higher concentration of anthocyanins was present in Utah raspberry juice (20.86 ± 0.35 mg cyanidin-3-glucoside eq./100 g), compared to pulp (13.96 ± 0.35). Anthocyanin content of juice and pulp were significantly positively correlated with dark color (L*). This is the first report of fractional differences in dry climate raspberries, and has implications for the juice and supplement industries.

Am besten testen Sie, ob eine Zeile in einer MySQL-Tabelle vorhanden ist
Ich versuche herauszufinden, ob eine Zeile in einer Tabelle vorhanden ist. Wenn Sie MySQL verwenden, ist es besser, eine Abfrage wie die folgende durchzuführen:
SELECT COUNT(*) AS total FROM table1 WHERE ...
und prüfen Sie, ob die Summe ungleich Null ist oder ob es besser ist, eine Abfrage wie die folgende durchzuführen:
SELECT * FROM table1 WHERE ... LIMIT 1
und überprüfen Sie, ob Zeilen zurückgegeben wurden?
In beiden Abfragen verwendet die WHERE-Klausel einen Index.

Sie könnten es auch mit versuchen
SELECT EXISTS(SELECT * FROM table1 WHERE ...)
per die Dokumentation
Nachstehend ein Kommentar:
SELECT EXISTS(SELECT 1 FROM table1 WHERE ...)

Ich habe in letzter Zeit einige Nachforschungen zu diesem Thema angestellt. Die Art der Implementierung muss anders sein, wenn das Feld ein TEXT-Feld ist, ein nicht eindeutiges Feld.
Ich habe einige Tests mit einem TEXT-Feld durchgeführt. In Anbetracht der Tatsache, dass wir eine Tabelle mit 1 Million Einträgen haben. 37 Einträge sind gleich 'etwas':
 - SELECT * FROM test WHERE texte LIKE '%something%' LIMIT 1 Mit mysql_num_rows(): 0.039061069488525s. (SCHNELLER)
 - SELECT count(*) as count FROM test WHERE text LIKE '%something%: 16.028197050095s.
 - SELECT EXISTS(SELECT 1 FROM test WHERE text LIKE '%something%'): 0.87045907974243s.
 - SELECT EXISTS(SELECT 1 FROM test WHERE text LIKE '%something%' LIMIT 1): 0.044898986816406s.
Aber jetzt, mit einem BIGINT PK-Feld, ist nur ein Eintrag gleich '321321':
 - SELECT * FROM test2 WHERE id ='321321' LIMIT 1 Mit mysql_num_rows(): 0.0089840888977051s.
 - SELECT count(*) as count FROM test2 WHERE id ='321321': 0,00033879280090332s.
 - SELECT EXISTS(SELECT 1 FROM test2 WHERE id ='321321'): 0,00023889541625977s.
 - SELECT EXISTS(SELECT 1 FROM test2 WHERE id ='321321' LIMIT 1): 0,00020313262939453s. (SCHNELLER)

Ich halte es für erwähnenswert, darauf hinzuweisen, dass in dieser Situation, obwohl dies in den Kommentaren angesprochen wurde:
SELECT 1 FROM my_table WHERE *indexed_condition* LIMIT 1
Ist überlegen gegenüber:
SELECT * FROM my_table WHERE *indexed_condition* LIMIT 1
Dies liegt daran, dass die erste Abfrage vom Index erfüllt werden kann, während für die zweite Abfrage eine Zeilensuche erforderlich ist (es sei denn, möglicherweise befinden sich alle Spalten der Tabelle im verwendeten Index).
Durch Hinzufügen der LIMIT -Klausel kann die Engine nach dem Auffinden einer Zeile angehalten werden.
Die erste Abfrage sollte vergleichbar sein mit:
SELECT EXISTS(SELECT * FROM my_table WHERE *indexed_condition*)
Was die gleichen Signale an die Engine sendet (1/* macht hier keinen Unterschied), aber ich würde trotzdem die 1 schreiben, um die Gewohnheit bei der Verwendung von EXISTS zu verstärken:
SELECT EXISTS(SELECT 1 FROM my_table WHERE *indexed_condition*)
Es kann sinnvoll sein, den Zeilenumbruch EXISTS hinzuzufügen, wenn Sie eine explizite Rückgabe benötigen, wenn keine Zeilen übereinstimmen.

Schlagen Sie vor, Count nicht zu verwenden, da count für db use SELECT 1 Immer zusätzliche Ladevorgänge verursacht und 1 zurückgibt, wenn Ihr Datensatz genau dort ist, andernfalls null zurückgibt und Sie damit umgehen können es.

Fatih Karatana
Manchmal ist es sehr praktisch, den Auto-Inkrement-Primärschlüssel (id) der Zeile abzurufen, falls vorhanden, und 0 wenn nicht.
So können Sie dies in einer einzelnen Abfrage tun:
SELECT IFNULL('id', COUNT(*)) FROM WHERE ...

] not necessarily identify a family or a relationship; it signified a place of residence. If farmer Ole Olsen Li moved from Li to another farm, such as Dal, he would then be known as Ole Olsen Dal. A farm laborer could be named in the same way, even though he was not related to the farmer."[1]
Another problem with including farm names as part of someone's surname is making the decision of which farm name to use. It is not uncommon for a person to live more than one place over the course of their lifetime. Would you use:
 - The farm on which they were born
 - The farm where they were living at the time of their confirmation
 - Where they lived when the census was taken
 - The farm they lived on when they were married
 - The farm where their children were born
 - The farm where they died
Farm Names in Local Histories[edit | edit source]
Many local histories (bygdebøker) published in Norway appear to include farm names as part of a person's name. This use is frequently misunderstood by persons who are not familiar with the literature and incorrectly assume it is the person's surname.
For example, this entry for Ljono farm from Ulvik gardsog ættesoga. Under the entries for Gjele, a smaller part of Ljono farm, Jon Asbjørnsson Håheim is identified[2]. Here Håheim is used to indicate which farm more information about him can be found, and does not mean Håheim is part of his name.
Norwegian-American Name Changes[edit | edit source]
Anders Halvorsen of Stordahl farm marries Kari Knutsdatter and has the following children:
 1. Halvor Andersen, b. 1830
 2. Anne Andersdatter, b. 1832
 3. Knut Andersen, b. 1834
 4. Mari Andersdatter, b. 1836
 5. Erik Andersen, b. 1838
 - Halvor Andersen lived at Bråten farm before emigrating to the United States in 1855. He goes by the name Halvor A. Bratten.
 - Anne Andersdatter emigrates with her brother in 1855. She uses the name Anderson when married in 1857 in Minnesota.
 - Knut Andersen emigrates in 1856. He uses the name Knut A. Stordahl.
 - Mari remained in Norway and was known as Mari Andersdatter.
 - Anders Halvorsen and his wife Kari Knutsdatter emigrated with the two youngest children in 1862. They and the two children carry on with the name Halvorson in the US.

The Architects Who Made London
15 February—4 June 2008
In the Architecture Space
Adjacent to the Royal Academy Restaurant
Installation photograph of 'The Architects Who Made London' display 2008. Photograph by Richard Bryant/ arcaid.co.uk
Against a backdrop of contextual photographs of London by Richard Bryant, this display looks at six architects from the mid-19th to the mid-20th century who have had a significant impact on the London we see today. Drawings, plans and photographs of their major London buildings, illustrate the impact of architects including Norman Shaw, Lutyens and Lubetkin on the capital.
Through their buildings and urban visions, their ideas influenced the physical and social structure of the city. In contrast to previous generations of architects, they faced often outwardly incompatible tasks, such as creating an identity for railway suburbs on the city's expanding fringe, giving a semblance of unity to the ceremonial approach to Buckingham Palace, or developing an architectural idiom for social housing.

Washington, Mar 19 : When it comes to recognising positive emotions like sensual pleasure, relief and achievement, there exists a strong cultural divide, according to researchers at University College London''s psychology department.
The scientists studied a range of non-verbal emotional vocalizations, such as screams and laughs, in two very different cultural groups.
They compared the responses of Westerners to those of the remote and culturally isolated semi-nomadic Himba people of Namibia.
And it was found that both groups recognised vocalizations expressing the six basic emotions - anger, disgust, fear, joy, sadness, and surprise.
This indicated that they, like facial expressions, are universally evolved functions.
However, when an additional set of positive emotions was introduced - achievement, sensual pleasure and relief - they were only reliably recognized by the Western subjects.
These newly discovered cultural variations suggested that the vocalization of some positive emotions might be learned socially, rather than representing products of evolution.
Describing the experiment as ''fascinating'' in her review, F1000 Faculty Member Argye Hills, of Johns Hopkins Medical Institute, said that the study "highlights the importance of considering a range of positive emotions in cross-cultural research."
The study has been published in Proceedings of the National Academy of Sciences of the USA. (ANI)
