If you are doing Unity Project. You can get this error.

Command PhaseScriptExecution failed with a nonzero exit code

The solution is very simple

https://forum.unity.com/threads/error-on-build.561706/

Pre-requisites: Have cocoapods installed

Not Needed: 1. Install "cocoapods" for installing run following line in your terminal: $sudo gem install cocoapods

2. Open your project folder using terminal
3. Run this line: chmod +x MapFileParser.sh
4. Run this line: chmod +x process_symbols.sh

It worked for me)

I think that installing "cocoapods" is not necessary, only step 3 and 4 enough to solve, but it does not work, you can try it.

From comments:

But, this code never stops (because of integer overflow) !?! Yves Daoust

For many numbers it will not overflow.

If it will overflow - for one of those unlucky initial seeds, the overflown number will very likely converge toward 1 without another overflow.

Still this poses interesting question, is there some overflow-cyclic seed number?

Any simple final converging series starts with power of two value (obvious enough?).

2^64 will overflow to zero, which is undefined infinite loop according to algorithm (ends only with 1), but the most optimal solution in answer will finish due to shr rax producing ZF=1.

Can we produce 2^64? If the starting number is 0x5555555555555555, it's odd number, next number is then 3n+1, which is 0xFFFFFFFFFFFFFFFF + 1 = 0. Theoretically in undefined state of algorithm, but the optimized answer of johnfound will recover by exiting on ZF=1. The cmp rax,1 of Peter Cordes will end in infinite loop (QED variant 1, "cheapo" through undefined 0 number).

How about some more complex number, which will create cycle without 0? Frankly, I'm not sure, my Math theory is too hazy to get any serious idea, how to deal with it in serious way. But intuitively I would say the series will converge to 1 for every number : 0 < number, as the 3n+1 formula will slowly turn every non-2 prime factor of original number (or intermediate) into some power of 2, sooner or later. So we don't need to worry about infinite loop for original series, only overflow can hamper us.

So I just put few numbers into sheet and took a look on 8 bit truncated numbers.

There are three values overflowing to 0: 227, 170 and 85 (85 going directly to 0, other two progressing toward 85).

But there's no value creating cyclic overflow seed.

Funnily enough I did a check, which is the first number to suffer from 8 bit truncation, and already 27 is affected! It does reach value 9232 in proper non-truncated series (first truncated value is 322 in 12th step), and the maximum value reached for any of the 2-255 input numbers in non-truncated way is 13120 (for the 255 itself), maximum number of steps to converge to 1 is about 128 (+-2, not sure if "1" is to count, etc...).

Interestingly enough (for me) the number 9232 is maximum for many other source numbers, what's so special about it? :-O 9232 = 0x2410 ... hmmm.. no idea.

Unfortunately I can't get any deep grasp of this series, why does it converge and what are the implications of truncating them to k bits, but with cmp number,1 terminating condition it's certainly possible to put the algorithm into infinite loop with particular input value ending as 0 after truncation.

But the value 27 overflowing for 8 bit case is sort of alerting, this looks like if you count the number of steps to reach value 1, you will get wrong result for majority of numbers from the total k-bit set of integers. For the 8 bit integers the 146 numbers out of 256 have affected series by truncation (some of them may still hit the correct number of steps by accident maybe, I'm too lazy to check).

Not the cleanest approach, but you can just clone the object each time you change the value?

   rawLapsData = Object.assign({}, rawLapsData);

I think I would prefer this approach over implementing your own ngDoCheck() but maybe someone like @GünterZöchbauer could chime in.

I deleted the file with main() function in my project when I wanted to change project type to static library.

I Forgot to change Properties -> General -> Configuration Type

from

Application(.exe)

to

Static Library (.lib)

This too gave me the same error.

The required file can be accessed as below from resource folder in scala

val file = scala.io.Source.fromFile(s"src/main/resources/app.config").getLines().mkString

Here's a fixed version of it: http://play.golang.org/p/w2ZcOzGHKR

The biggest fix that was needed is when Unmarshalling an array, that property needs to be an array/slice in the struct as well.

For example:

{ "things": ["a", "b", "c"] }

Would Unmarshal into a:

type Item struct {
    Things []string
}

And not into:

type Item struct {
    Things string
}

The other thing to watch out for when Unmarshaling is that the types line up exactly. It will fail when Unmarshalling a JSON string representation of a number into an int or float field -- "1" needs to Unmarshal into a string, not into an int like we saw with ShippingAdditionalCost int

In the error message, instead of telling you that you can't concatenate two objects by showing their values (a string and None in this example), the Python interpreter tells you this by showing the types of the objects that you tried to concatenate. The type of every string is str while the type of the single None instance is called NoneType.

You normally do not need to concern yourself with NoneType, but in this example it is necessary to know that type(None) == NoneType.

Use display: flex to stretch your divs:

JSFIDDLE

When you have everything #included, an unresolved external symbol is often a missing * or & in the declaration or definition of a function.

I was having the same problem while running bulk tests for an assignment. Turns out when I relocated some iostream operations (printing to console) from class constructor to a method in class it was solved.

I assume it was something to do with iostream manipulations in the constructor.

Here is the fix:

// Before
CommandPrompt::CommandPrompt() : afs(nullptr), aff(nullptr) {
    cout << "Some text I was printing.." << endl;
};


// After
CommandPrompt::CommandPrompt() : afs(nullptr), aff(nullptr) {

};

Please feel free to explain more what the error is behind the scenes since it goes beyond my cpp knowledge.

HTTP Error 413.0 - Request Entity Too Large

The page was not displayed because the request entity is too large.

Most likely causes:

• The Web server is refusing to service the request because the request entity is too large.

• The Web server cannot service the request because it is trying to negotiate a client certificate but the request entity is too large.

• The request URL or the physical mapping to the URL (i.e., the physical file system path to the URL's content) is too long.

Things you can try:

• Verify that the request is valid.

• If using client certificates, try:

  • Increasing system.webServer/serverRuntime@uploadReadAheadSize

  • Configure your SSL endpoint to negotiate client certificates as part of the initial SSL handshake. (netsh http add sslcert ... clientcertnegotiation=enable) .vs\config\applicationhost.config

Solve this by editing \.vs\config\applicationhost.config. Switch serverRuntime from Deny to Allow like this:

<section name="serverRuntime" overrideModeDefault="Allow" />

If this value is not edited, you will get an error like this when setting uploadReadAheadSize:

HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid.

This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".

Then edit Web.config with the following values:

<system.webServer>
  <serverRuntime uploadReadAheadSize="10485760" />
...

I've just solved this problem on a site I'm working on, and thought I would share it in the hope it helps someone.

My solution takes the distance from the footer to the top of the page - if the user has scrolled further than this, it pulls the sidebar back up with a negative margin.

$(window).scroll(() => { 
  // Distance from top of document to top of footer.
  topOfFooter = $('#footer').position().top;
  // Distance user has scrolled from top, adjusted to take in height of sidebar (570 pixels inc. padding).
  scrollDistanceFromTopOfDoc = $(document).scrollTop() + 570;
  // Difference between the two.
  scrollDistanceFromTopOfFooter = scrollDistanceFromTopOfDoc - topOfFooter;

  // If user has scrolled further than footer,
  // pull sidebar up using a negative margin.
  if (scrollDistanceFromTopOfDoc > topOfFooter) {
    $('#cart').css('margin-top',  0 - scrollDistanceFromTopOfFooter);
  } else  {
    $('#cart').css('margin-top', 0);
  }
});

Might it be possible that you're using a WCF-based web service reference? By default, the ServiceThrottlingBehavior.MaxConcurrentCalls is 16.

You could try updating your service reference behavior's <serviceThrottling> element

<serviceThrottling
    maxConcurrentCalls="999" 
    maxConcurrentSessions="999" 
    maxConcurrentInstances="999" />

(Note that I'd recommend the settings above.) See MSDN for more information how to configure an appropriate <behavior> element.

This is due to using obsolete mysql-connection-java version, your MySQl is updated but not your MySQL jdbc Driver, you can update your connection jar from the official site Official MySQL Connector site. Good Luck.

Long time since I've done Assembly programming, but this link might be useful...

The processor has a collection of registers which are used to store data. Some of these are direct values while others are pointing to an area within RAM. Registers do tend to be used for certain specific actions and every operand in assembly will require a certain amount of data in specific registers.

The stack pointer is mostly used when you're calling other procedures. With modern compilers, a bunch of data will be dumped first on the stack, followed by the return address so the system will know where to return once it's told to return. The stack pointer will point at the next location where new data can be pushed to the stack, where it will stay until it's popped back again.

Base registers or segment registers just point to the address space of a large amount of data. Combined with a second regiser, the Base pointer will divide the memory in huge blocks while the second register will point at an item within this block. Base pointers therefor point to the base of blocks of data.

Do keep in mind that Assembly is very CPU specific. The page I've linked to provides information about different types of CPU's.

The problem is that the EventLog.SourceExists tries to access the EventLog\Security key, access which is only permitted for an administrator.

A common example for a C# Program logging into EventLog is:

string sSource;
string sLog;
string sEvent;

sSource = "dotNET Sample App";
sLog = "Application";
sEvent = "Sample Event";

if (!EventLog.SourceExists(sSource))
    EventLog.CreateEventSource(sSource, sLog);

EventLog.WriteEntry(sSource, sEvent);
EventLog.WriteEntry(sSource, sEvent, EventLogEntryType.Warning, 234);

However, the following lines fail if the program hasn't administrator permissions and the key is not found under EventLog\Application as EventLog.SourceExists will then try to access EventLog\Security.

if (!EventLog.SourceExists(sSource))
    EventLog.CreateEventSource(sSource, sLog);

Therefore the recommended way is to create an install script, which creates the corresponding key, namely:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application\dotNET Sample App

One can then remove those two lines.

You can also create a .reg file to create the registry key. Simply save the following text into a file create.reg:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application\dotNET Sample App]

I can't comment up thread due to lack of rep. Another commenter stated they couldn't migrate from a lower version to a higher version of IIS. This is true if you don't merge some files, but if you do you can as I just migrated my IIS 7.5 site to IIS 8.0 using the answer posted by chews.

When the export is created (II7.5), there are two key files (administration.config and applicationHost.config) which have references to resources on the IIS7.5 server. For example, a DLL will be referred with a public key and version specific to 7.5. These are NOT the same on the IIS8 server. The feature configuration may differ as well (I ensured mine were identical). There are some new features in 8 which will never exist in 7.5.

If you are brave enough to merge the two files - it will work. I had to uninstall IIS once because I messed it up, but got it the second time.

I used a merge tool (Beyond Compare) and without something equivalent it would be a huge PITA - but was pretty easy with a good diff tool (five minutes).

To do the merge, the 8.0 files need to be diffed against the exported 7.5 files BEFORE an import is attempted. For the most part, the 8.0 files need to overwrite the server specific stuff in the exported 7.5 files, while leaving the site/app pool specific stuff.

I found that administration.config was almost identical, sans the version info of many entries. This one was easy.

The applicationHost.config has a lot more differences. Some entries are ordered differently, but otherwise identical, so you will have to pick through each difference and figure it out.

I put my 7.5 export files in the System32\inetsrv\config\Export folder prior to merging.

I merged FROM folder System32\inetsrv\config to folder System32\inetsrv\config\Export for both files I mentioned above. I pushed over everything in the FROM files except site specific tags/elements (e.g. applicationPools, customMetadata, sites, authentication). Of special note, there were also many site specific "location" tag blocks that I had to keep, but the new server had its own "location" tag block with server specific defaults that has to be kept.

Lastly, do note that if you use service accounts, these cached passwords are junk and will have to be re-entered for your app pools. None of my sites worked initially, but all that was required was re-entering the passwords for all my app pools and I was up and running.

If someone who can comment mention this post down thread - it will probably help someone else like me who has many sites on one server with complicated configurations.

Stuart

I had a similar problem with the same error message:

System.Web.Services.Protocols.SoapException: Server did not recognize the value of HTTP Header SOAPAction:

We utilize dynamic URL's in our web service calls. We have a central configuration server that manages the location of all web service calls so that our code can run in DEV, test or live without recompiling. The URL for a specific web service call for the test environment was incorrect in our configuration server. The web service call was being sent to the wrong server and the wrong web service.

So this error can simply be the result of the web service request not matching the web service being called.

It took running fiddler on the Web App server to see that the actual call was to the incorrect web service.

I've always used FMOD for things like this because it's free for non-commercial use and works well.

That said, I'd gladly switch to something that's smaller (FMOD is ~300k) and open-source. Super bonus points if it's fully managed so that I can compile / merge it with my .exe and not have to take extra care to get portability to other platforms...

(FMOD does portability too but you'd obviously need different binaries for different platforms)

I've seen people mention a rename command, but it is not routinely available on Unix systems (as opposed to Linux systems, say, or Cygwin - on both of which, rename is an executable rather than a script). That version of rename has a fairly limited functionality:

rename from to file ...

It replaces the from part of the file names with the to, and the example given in the man page is:

rename foo foo0 foo? foo??

This renames foo1 to foo01, and foo10 to foo010, etc.

I use a Perl script called rename, which I originally dug out from the first edition Camel book, circa 1992, and then extended, to rename files.

            print STDERR "rename failed: $was - $!\n"

        }
    }
    else
    {
        print STDERR "$_ - $!\n";

This allows you to write any Perl substitute or transliterate command to map file names. In the specific example requested, you'd use:

rename 's/^/new./' original.filename

Instead of concatenating paths like in some answers, I use File.expand_path:

Dir[File.expand_path('importers/*.rb', File.dirname(__FILE__))].each do |file|
  require file
end

Update:

Instead of using File.dirname you could do the following:

Dir[File.expand_path('../importers/*.rb', __FILE__)].each do |file|
  require file
end

Where .. strips the filename of __FILE__.

so just try to use the sugested lines of my xml configuration.

There is the hint feature? You can use the setHint() to set it, or set it in XML (though you probably don't want that, because the XML doesn't 'know' the name/adress of your user :) )

Let's fill in the gaps in your code, by adding the other branches in the logic, and see what happens:

SQL> DECLARE
  2   str1  varchar2(4000);
  3   str2  varchar2(4000);
  4  BEGIN
  5     str1:='';

  7     IF(str1<>str2) THEN

  9     ELSIF (str1=str2) THEN
 10      dbms_output.put_line('The two strings are the same');
 11     ELSE
 12      dbms_output.put_line('Who knows?');
 13     END IF;
 14   END;
 15  /
Who knows?

PL/SQL procedure successfully completed.

SQL>

So the two strings are neither the same nor are they not the same? Huh?

It comes down to this. Oracle treats an empty string as a NULL. If we attempt to compare a NULL and another string the outcome is not TRUE nor FALSE, it is NULL. This remains the case even if the other string is also a NULL.

I arrived here from a google search, since my other code is 'tidy' so leaving the 'tidy' way for anyone who else who may find it useful

library(dplyr)
iris %>% 
  mutate(Species = ifelse(as.character(Species) == "virginica", "newValue", as.character(Species)))

map :

is a higher-order method that takes a function as input and applies it to each element in the source RDD.

http://commandstech.com/difference-between-map-and-flatmap-in-spark-what-is-map-and-flatmap-with-examples/

flatMap:

a higher-order method and transformation operation that takes an input function.

function _modulename_getData($field, $table) {
  try {
    if (empty($field)) {
      throw new Exception("The field is undefined."); 
    }
    // rest of code here...
  }
  catch (Exception $e) {
    /*
        Here you can either echo the exception message like: 
        echo $e->getMessage(); 

        Or you can throw the Exception Object $e like:
        throw $e;
    */
  }
}

You could write a function that runs getElementsByTagName('*'), and returns only those elements with a "data-foo" attribute:

function getAllElementsWithAttribute(attribute)
{
  var matchingElements = [];
  var allElements = document.getElementsByTagName('*');
  for (var i = 0, n = allElements.length; i < n; i++)
  {
    if (allElements[i].getAttribute(attribute) !== null)
    {
      // Element exists with attribute. Add to array.
      matchingElements.push(allElements[i]);
    }
  }
  return matchingElements;
}

Then,

getAllElementsWithAttribute('data-foo');

I experienced this error and did all the suggestions from you guys here but none had any effect for my error.

I caught the culprit: if you are using *.ini file for your system, you might want to check what server name was input there and make sure it is the same as the one in your web.config connection string.

Just to add to the other examples, there are inner(nested) classes that appear with the $ sign. For example:

public class Test {

    private static void privateMethod() {
        throw new RuntimeException();
    }

    public static void main(String[] args) throws Exception {
        Runnable runnable = new Runnable() {
            @Override public void run() {
                privateMethod();
            }
        };
        runnable.run();
    }
}

Will result in this stack trace:

Exception in thread "main" java.lang.RuntimeException
        at Test.privateMethod(Test.java:4)
        at Test.access$000(Test.java:1)
        at Test$1.run(Test.java:10)
        at Test.main(Test.java:13)

If you want to handle different 404s in different ways, consider catching them in your controllers. This will allow you to do things like tracking the number of 404s generated by different user groups, have support interact with users to find out what went wrong / what part of the user experience might need tweaking, do A/B testing, etc.

I have here placed the base logic in ApplicationController, but it can also be placed in more specific controllers, to have special logic only for one controller.

The reason I am using an if with ENV['RESCUE_404'], is so I can test the raising of AR::RecordNotFound in isolation. In tests, I can set this ENV var to false, and my rescue_from would not fire. This way I can test the raising separate from the conditional 404 logic.

class ApplicationController < ActionController::Base

  rescue_from ActiveRecord::RecordNotFound, with: :conditional_404_redirect if ENV['RESCUE_404']

private

  def conditional_404_redirect
    track_404(@current_user)
    if @current_user.present?
      redirect_to_user_home          
    else
      redirect_to_front
    end
  end

end

Everything is possible (or almost) with css, just use:

display: none; //to hide

display: table-cell //to show

My numeric control:

function CheckNumeric(event) {
    var _key = (window.Event) ? event.which : event.keyCode;
    if (_key > 95 && _key < 106) {
        return true;
    }
    else if (_key > 47 && _key < 58) {
        return true;
    }
    else {
        return false;
    }
}

<input type="text" onkeydown="return CheckNumerick(event);" />

Download Microsoft Drivers for PHP for SQL Server. Extract the files and use one of:

File                             Thread Safe         VC Bulid
php_sqlsrv_53_nts_vc6.dll           No                  VC6
php_sqlsrv_53_nts_vc9.dll           No                  VC9
php_sqlsrv_53_ts_vc6.dll            Yes                 VC6
php_sqlsrv_53_ts_vc9.dll            Yes                 VC9

You can see the Thread Safety status in phpinfo().

Add the correct file to your ext directory and the following line to your php.ini:

extension=php_sqlsrv_53_*_vc*.dll

Use the filename of the file you used.

As Gordon already posted this is the new Extension from Microsoft and uses the sqlsrv_* API instead of mssql_*

Update:
On Linux you do not have the requisite drivers and neither the SQLSERV Extension.
Look at Connect to MS SQL Server from PHP on Linux? for a discussion on this.

In short you need to install FreeTDS and YES you need to use mssql_* functions on linux. see update 2

To simplify things in the long run I would recommend creating a wrapper class with requisite functions which use the appropriate API (sqlsrv_* or mssql_*) based on which extension is loaded.

Update 2: You do not need to use mssql_* functions on linux. You can connect to an ms sql server using PDO + ODBC + FreeTDS. On windows, the best performing method to connect is via PDO + ODBC + SQL Native Client since the PDO + SQLSRV driver can be incredibly slow.

You can use the Sum function, but you'll have to convert the strings to integers, like so:

int total = monValues.Sum(x => Convert.ToInt32(x));

In this step I have Set the variable first:

<c:set var="structureId" value="<%=article.getStructureId()%>" scope="request"></c:set>

In this step I have checked the variable empty or not:

 <c:if test="${not empty structureId }">
    <a href="javascript:void(0);">Change Design</a>
 </c:if>

exec('wget http://<url to the php script>') worked for me.

It enable me to integrate two php files that were designed as web pages and run them as code to do work without affecting the calling page

Don't use document.write, here is workaround:

var script = document.createElement('script');  
script.src = "....";  
document.head.appendChild(script);

Although I am very late to this but after seeing some legitimate questions for those who wanted to use INSERT-SELECT query with GROUP BY clause, I came up with the work around for this.

Taking further the answer of Marcus Adams and accounting GROUP BY in it, this is how I would solve the problem by using Subqueries in the FROM Clause

INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, 
                inact, inadur, inadist, 
                smlct, smldur, smldist, 
                larct, lardur, lardist, 
                emptyct, emptydur)
SELECT sb.id, uid, sb.location, sb.animal, sb.starttime, sb.endtime, sb.entct, 
       sb.inact, sb.inadur, sb.inadist, 
       sb.smlct, sb.smldur, sb.smldist, 
       sb.larct, sb.lardur, sb.lardist, 
       sb.emptyct, sb.emptydur
FROM
(SELECT id, uid, location, animal, starttime, endtime, entct, 
       inact, inadur, inadist, 
       smlct, smldur, smldist, 
       larct, lardur, lardist, 
       emptyct, emptydur 
FROM tmp WHERE uid=x
GROUP BY location) as sb
ON DUPLICATE KEY UPDATE entct=sb.entct, inact=sb.inact, ...

you need to cast int to str before concatenating. for that use str(temperature). Or you can print the same output using , if you don't want to convert like this.

print("the furnace is now",temperature , "degrees!")

Minimal use of FormData to submit an AJAX request

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=Edge, chrome=1"/>
<script>
"use strict";
function submitForm(oFormElement)
{
  var xhr = new XMLHttpRequest();
  xhr.onload = function(){ alert (xhr.responseText); } // success case
  xhr.onerror = function(){ alert (xhr.responseText); } // failure case
  xhr.open (oFormElement.method, oFormElement.action, true);
  xhr.send (new FormData (oFormElement));
  return false;
}
</script>
</head>

<body>
<form method="post" action="somewhere" onsubmit="return submitForm(this);">
  <input type="hidden" value="person"   name="user" />
  <input type="hidden" value="password" name="pwd" />
  <input type="hidden" value="place"    name="organization" />
  <input type="hidden" value="key"      name="requiredkey" />
  <input type="submit" value="post request"/>
</form>
</body>
</html>

Remarks

1. This does not fully answer the OP question because it requires the user to click in order to submit the request. But this may be useful to people searching for this kind of simple solution.

2. This example is very simple and does not support the GET method. If you are interesting by more sophisticated examples, please have a look at the excellent MDN documentation. See also similar answer about XMLHttpRequest to Post HTML Form.

3. Limitation of this solution: As pointed out by Justin Blank and Thomas Munk (see their comments), FormData is not supported by IE9 and lower, and default browser on Android 2.3.

Here's intuitive understanding of runtime complexity of Euclid's algorithm. The formal proofs are covered in various texts such as Introduction to Algorithms and TAOCP Vol 2.

First think about what if we tried to take gcd of two Fibonacci numbers F(k+1) and F(k). You might quickly observe that Euclid's algorithm iterates on to F(k) and F(k-1). That is, with each iteration we move down one number in Fibonacci series. As Fibonacci numbers are O(Phi ^ k) where Phi is golden ratio, we can see that runtime of GCD was O(log n) where n=max(a, b) and log has base of Phi. Next, we can prove that this would be the worst case by observing that Fibonacci numbers consistently produces pairs where the remainders remains large enough in each iteration and never become zero until you have arrived at the start of the series.

We can make O(log n) where n=max(a, b) bound even more tighter. Assume that b >= a so we can write bound at O(log b). First, observe that GCD(ka, kb) = GCD(a, b). As biggest values of k is gcd(a,c), we can replace b with b/gcd(a,b) in our runtime leading to more tighter bound of O(log b/gcd(a,b)).

Because you are asking the compiler to initialize a static variable with code that is inherently dynamic.

Will not necessarily work

• Backup / Restore - will not work when the target is an earlier MS SQL version.

• Copy Database - will not work when the target is SQL Server Express: "The destination server cannot be a SQL Server 2005 or later Express instance."

• Data import - Will not copy the schema.

Will work

• Script generation - Tasks -> Generate Scripts. Make sure you set the desired target SQL Server version on the Set Scripting Options -> Advanced page. You can also choose there whether to copy schema, data, or both. Note that in the generated script, you may need to change the DATA folder for the mdf/ldf files if moving from non-express to express or vice versa.

• Microsoft SQL Server Database Publishing Services - comes with SQL Server 2005 and above, I think. Download the latest version from here. Prerequisites: sqlncli.msi/sqlncli_x64.msi/sqlncli_ia64.msi, SQLServer2005_XMO.msi/SQLServer2005_XMO_x64.msi/SQLServer2005_XMO_ia64.msi (download here).

In current version of Jekyll, it defaults to http://127.0.0.1:4000/.
This is good, if you are connected to a network but do not want anyone else to access your application.

However it may happen that you want to see how your application runs on a mobile or from some other laptop/computer.

In that case, you can use

jekyll serve --host 0.0.0.0

This binds your application to the host & next use following to connect to it from some other host

http://host's IP adress/4000 

For me the major difference is all the ancilliary files that TFS will add to your solution (.vssscc) to 'support' TFS - we've had recent issues with these files ending up mapped to the wrong branch, which lead to some interesting debugging...

A few people have an example using setAttribute which I like. However it assumes you don't have any styles currently set. I would maybe do something like:

nFilter.setAttribute('style', nFilter.getAttribute('style') + ';width:330px;float:left;');

Or make it into a helper function like this:

function setStyle(el, css){
  el.setAttribute('style', el.getAttribute('style') + ';' + css);
}

setStyle(nFilter, 'width:330px;float:left;');

This makes sure that you can add styles to it continuously and it won't remove any style currently set by always appending to the current styles. It also adds an extra semi colon so that if there is a style ever missing one it will append another to make sure it is fully delimited.

git branch -r says the object name is invalid, because that branch name isn't in Git's local branch list. Update your local branch list from origin with:

git remote update

And then try checking out your remote branch again.

This worked for me.

I believe git fetch pulls in all remote branches, which is not what the original poster wanted.

There are multiple places where Linux can have limits on the number of file descriptors you are allowed to open.

You can check the following:

cat /proc/sys/fs/file-max

That will give you the system wide limits of file descriptors.

On the shell level, this will tell you your personal limit:

ulimit -n

This can be changed in /etc/security/limits.conf - it's the nofile param.

However, if you're closing your sockets correctly, you shouldn't receive this unless you're opening a lot of simulataneous connections. It sounds like something is preventing your sockets from being closed appropriately. I would verify that they are being handled properly.

I've always used this syntax, which yields more predictable results than using !=.

<xsl:when test="not($AccountNumber = '12345') and not($Balance = '0')" />

SDK developers prefer to define their own types using typedef. This allows changing underlying types only in one place, without changing all client code. It is important to follow this convention. DWORD is unlikely to be changed, but types like DWORD_PTR are different on different platforms, like Win32 and x64. So, if some function has DWORD parameter, use DWORD and not unsigned int, and your code will be compiled in all future windows headers versions.

If you want to delete using line numbers you can use:

:startingline, last line d

Example:

:7,20 d

This example will delete line 7 to 20.

Read line by line, not the whole file:

for line in open(file_name, 'rb'):
    # process line here

Even better use with for automatically closing the file:

with open(file_name, 'rb') as f:
    for line in f:
        # process line here

The above will read the file object using an iterator, one line at a time.

The answer is to DISABLE "Enable auto-completion on each input". Tested and works perfectly.

When you open phpinfo() see if the thread safety is enable or not enable also see the version of php and see MSVC-- what is the number in place of -- and see the architecture these all things help u to get the suitable php driver

I take different approach, you may agree or not but I want to control from .properties file instead of compiled Java code

Inside application.properties file

endpoint.url = https://yourHost/resource?requestParam1={0}&requestParam2={1}

Java code goes here, you can write if or switch condition to find out if endpoint URL in .properties file has @PathVariable (contains {}) or @RequestParam (yourURL?key=value) etc... then invoke method accordingly... that way its dynamic and not need to code change in future one stop shop...

I'm trying to give more of idea than actual code here ...try to write generic method each for @RequestParam, and @PathVariable etc... then call accordingly when needed

  @Value("${endpoint.url}")
  private String endpointURL;
  // you can use variable args feature in Java
  public String requestParamMethodNameHere(String value1, String value2) {
    RestTemplate restTemplate = new RestTemplate();
    restTemplate
           .getMessageConverters()
           .add(new MappingJackson2HttpMessageConverter());

    HttpHeaders headers = new HttpHeaders();
    headers.set("Accept", MediaType.APPLICATION_JSON_VALUE);
    HttpEntity<String> entity = new HttpEntity<>(headers);

    try {
      String formatted_URL = MessageFormat.format(endpointURL, value1, value2);
      ResponseEntity<String> response = restTemplate.exchange(
                    formatted_URL ,
                    HttpMethod.GET,
                    entity,
                    String.class);
     return response.getBody();
    } catch (Exception e) { e.printStackTrace(); }

You can bind listeners to one common functions -

$(window).bind("load resize scroll",function(e){
  // do stuff
});

Or another way -

$(window).bind({
     load:function(){

     },
     resize:function(){

     },
     scroll:function(){

    }
});

Alternatively, instead of using .bind() you can use .on() as bind directly maps to on(). And maybe .bind() won't be there in future jquery versions.

$(window).on({
     load:function(){

     },
     resize:function(){

     },
     scroll:function(){

    }
});

This below worked for me:

    SELECT count(*)
    INTO @exist
    FROM information_schema.columns
    WHERE table_schema = 'mydatabase'
    and COLUMN_NAME = 'mycolumn'
    AND table_name = 'mytable' LIMIT 1;

    set @query = IF(@exist <= 0, 'ALTER TABLE mydatabase.`mytable`  ADD COLUMN `mycolumn` MEDIUMTEXT NULL',
    'select \'Column Exists\' status');

    prepare stmt from @query;

    EXECUTE stmt;

A simplified version, I had a similar issue to this when using the Google Maps JS SDK.

My solution was to extract the divand ViewChild into it's own child component which when used in the parent component was able to be hid/displayed using an *ngIf.

Before

HomePageComponent Template

<div *ngIf="showMap">
  <div #map id="map" class="map-container"></div>
</div>

HomePageComponent Component

@ViewChild('map') public mapElement: ElementRef; 

public ionViewDidLoad() {
    this.loadMap();
});

private loadMap() {

  const latLng = new google.maps.LatLng(-1234, 4567);
  const mapOptions = {
    center: latLng,
    zoom: 15,
    mapTypeId: google.maps.MapTypeId.ROADMAP,
  };
   this.map = new google.maps.Map(this.mapElement.nativeElement, mapOptions);
}

public toggleMap() {
  this.showMap = !this.showMap;
 }

After

MapComponent Template

 <div>
  <div #map id="map" class="map-container"></div>
</div>

MapComponent Component

@ViewChild('map') public mapElement: ElementRef; 

public ngOnInit() {
    this.loadMap();
});

private loadMap() {

  const latLng = new google.maps.LatLng(-1234, 4567);
  const mapOptions = {
    center: latLng,
    zoom: 15,
    mapTypeId: google.maps.MapTypeId.ROADMAP,
  };
   this.map = new google.maps.Map(this.mapElement.nativeElement, mapOptions);
}

HomePageComponent Template

<map *ngIf="showMap"></map>

HomePageComponent Component

public toggleMap() {
  this.showMap = !this.showMap;
 }

ASP.NET Core 3.1

This is my implementation of the feature, it works on server side as well as with jquery validation unobtrusive with a custom error message just like any other attribute:

The attribute:

  [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = false)]
    public class MustBeIntegerAttribute : ValidationAttribute, IClientModelValidator
    {
        public void AddValidation(ClientModelValidationContext context)
        {
            MergeAttribute(context.Attributes, "data-val", "true");
            var errorMsg = FormatErrorMessage(context.ModelMetadata.GetDisplayName());
            MergeAttribute(context.Attributes, "data-val-mustbeinteger", errorMsg);
        }

        public override bool IsValid(object value)
        {
            return int.TryParse(value?.ToString() ?? "", out int newVal);
        }

        private bool MergeAttribute(
              IDictionary<string, string> attributes,
              string key,
              string value)
        {
            if (attributes.ContainsKey(key))
            {
                return false;
            }
            attributes.Add(key, value);
            return true;
        }
    }

Client side logic:

$.validator.addMethod("mustbeinteger",
    function (value, element, parameters) {
        return !isNaN(parseInt(value)) && isFinite(value);
    });

$.validator.unobtrusive.adapters.add("mustbeinteger", [], function (options) {
    options.rules.mustbeinteger = {};
    options.messages["mustbeinteger"] = options.message;
});

And finally the Usage:

 [MustBeInteger(ErrorMessage = "You must provide a valid number")]
 public int SomeNumber { get; set; }

FWIW, you can provide an error message like so:

USERNAME=${1:?"Specify a username"}

This displays a message like this and exits with code 1:

./myscript.sh
./myscript.sh: line 2: 1: Specify a username

A more complete example of everything:

#!/bin/bash
ACTION=${1:?"Specify 'action' as argv[1]"}
DIRNAME=${2:-$PWD}
OUTPUT_DIR=${3:-${HOMEDIR:-"/tmp"}}

echo "$ACTION"
echo "$DIRNAME"
echo "$OUTPUT_DIR"

Output:

$ ./script.sh foo
foo
/path/to/pwd
/tmp

$ export HOMEDIR=/home/myuser
$ ./script.sh foo
foo
/path/to/pwd
/home/myuser

• $ACTION takes the value of the first argument, and exits if empty
• $DIRNAME is the 2nd argument, and defaults to the current directory
• $OUTPUT_DIR is the 3rd argument, or $HOMEDIR (if defined), else, /tmp. This works on OS X, but I'm not positive that it's portable.

select ID from A where ID not in (select ID from B);

or

select ID from A except select ID from B;

Your second question:

delete from A where ID not in (select ID from B);

Usually what you choose will depend on which methods you need access to. In general - IEnumerable<> (MSDN: http://msdn.microsoft.com/en-us/library/system.collections.ienumerable.aspx) for a list of objects that only needs to be iterated through, ICollection<> (MSDN: http://msdn.microsoft.com/en-us/library/92t2ye13.aspx) for a list of objects that needs to be iterated through and modified, List<> for a list of objects that needs to be iterated through, modified, sorted, etc (See here for a full list: http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx).

From a more specific standpoint, lazy loading comes in to play with choosing the type. By default, navigation properties in Entity Framework come with change tracking and are proxies. In order for the dynamic proxy to be created as a navigation property, the virtual type must implement ICollection.

A navigation property that represents the "many" end of a relationship must return a type that implements ICollection, where T is the type of the object at the other end of the relationship. -Requirements for Creating POCO Proxies^MSDN

What worked for me is to change the access of the Git repository from private to public.

In my memory, excel (versions >= 2007) limits the power 2 of 20: 1.048.576 lines.

Csv is over to this boundary, like ordinary text file. So you will be care of the transfer between two formats.

you can:

use integer;

it is explained by Michael Ratanapintha or else use manually:

$a=3.7;
$b=2.1;

$c=int(int($a)/int($b));

notice, 'int' is not casting. this is function for converting number to integer form. this is because Perl 5 does not have separate integer division. exception is when you 'use integer'. Then you will lose real division.

Actually without PDB files and symbolic information they have it would be impossible to create a successful crash report (memory dump files) and Microsoft would not have the complete picture what caused the problem.

And so having PDB improves crash reporting.

@Logan has put this perfectly. Potentially something worth pointing out also is that you can use

printf(whatever you want to print);

For example if you were printing a string:

printf("hello");

Came up with a quick and dirty fix to this. Just used <select onchange='this.options[this.selectedIndex].onclick();> <option onclick='alert("hello world")' ></option> </select>

Hope this helps

If your script's redirect contains a variable, and the script body defines that variable in a section enclosed by parenthesis, you will get the "ambiguous redirect" error. Here's a reproducible example:

1. vim a.sh to create the script
2. edit script to contain (logit="/home/ubuntu/test.log" && echo "a") >> ${logit}
3. chmod +x a.sh to make it executable
4. a.sh

If you do this, you will get "/home/ubuntu/a.sh: line 1: $logit: ambiguous redirect". This is because

"Placing a list of commands between parentheses causes a subshell to be created, and each of the commands in list to be executed in that subshell, without removing non-exported variables. Since the list is executed in a subshell, variable assignments do not remain in effect after the subshell completes."

From Using parenthesis to group and expand expressions

To correct this, you can modify the script in step 2 to define the variable outside the parenthesis: logit="/home/ubuntu/test.log" && (echo "a") >> $logit

When you hit on the submit button, the page is sent to the server. If you want to send it async, you can do it with ajax.

The other answers are good if you are dealing only with numbers using the format string, but this is good when you may have strings that need to be padded (although admittedly a little diffent than the question asked, seems similar in spirit). Also, be careful if the string is longer than the pad.

   let str = "a str"
   let padAmount = max(10, str.count)
   String(repeatElement("-", count: padAmount - str.count)) + str

Output "-----a str"

Here's what u can also try....

run your application....while it is still running launch your command prompt

while your application is running type netstat -n on the command prompt. You should see a list of TCP/IP connections. Check if your list is not very long. Ideally you should have less than 5 connections in the list. Check the status of the connections.
If you have too many connections with a TIME_WAIT status it means the connection has been closed and is waiting for the OS to release the resources. If you are running on Windows, the default ephemeral port rang is between 1024 and 5000 and the default time it takes Windows to release the resource from TIME_WAIT status is 4 minutes. So if your application used more then 3976 connections in less then 4 minutes, you will get the exception you got.

Suggestions to fix it:

1. Add a connection pool to your connection string.

If you continue to receive the same error message (which is highly unlikely) you can then try the following: (Please don't do it if you are not familiar with the Windows registry)

1. Run regedit from your run command. In the registry editor look for this registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters:

Modify the settings so they read:

MaxUserPort = dword:00004e20 (10,000 decimal) TcpTimedWaitDelay = dword:0000001e (30 decimal)

This will increase the number of ports to 10,000 and reduce the time to release freed tcp/ip connections.

Only use suggestion 2 if 1 fails.

Thank you.

Please "include" both Controller and the module(s) where the controller and the functions called in the Controller are.

module(theModule);

(number/10**x)%10

You can use this in a loop, where number is the full number, x is each iteration of the loop (0,1,2,3,...,n) with n being the stop point. x = 0 gives the ones place, x = 1 gives the tens, x = 2 gives the hundreds, and so on. Keep in mind that this will give the value of the digits from right to left, so this might not be the for an ISBN but it will still isolate each digit.

Use a Temp Table or a Table variable, e.g.

select 'A' as [value]
into #tmp
union
select 'B'
union 
select 'C'

and then

SELECT   
blah 
FROM    foo 
WHERE   myField IN (select [value] from #tmp) 

or

SELECT   
f.blah 
FROM foo f INNER JOIN #tmp t ON f.myField = t.[value]

One suggestion is to use LINQ to Entity Framework only for single-record CRUD statements.

For more involved queries, searches, reporting, etc, write a stored procedure and add it to the Entity Framework model as described on MSDN.

This is the approach I've taken with a couple of my sites and it seems to be a good compromise between productivity and performance. Entity Framework will not always generate the most efficient SQL for the task at hand. And rather than spending the time to figure out why, writing a stored procedure for the more complex queries actually saves time for me. Once you're familiar with the process, it's not too much of a hassle to add stored procs to your EF model. And of course the benefit of adding it to your model is that you get all that strongly typed goodness that comes from using an ORM.

there you go

date('d.m.Y',strtotime("-1 days"));

this will work also if month change

You could use this jQuery plugin waitForImage or you could put you images into an hidden div or (width:0 and height:0) and use onload event on images.

If you only have like 2-3 images you can bind events and trigger them in a chain so after every image you can do some code.

Your questions:

Q 1.) I would like to know why it returns all the texts that following the div?
It should not and I think in will not. It returns all div with 'id' attribute value equal 'containter' (and all children of this). But you are printing the results with ele.getText() Where getText will return all text content of all children of your result.

Get the visible (i.e. not hidden by CSS) innerText of this element, including sub-elements, without any leading or trailing whitespace.
Returns:
The innerText of this element.

Q 2.) how should I modify the code so it just return first or first few nodes that follow the parent note
This is not really clear what you are looking for. Example:

<p1> <div/> </p1 <p2/> 

The following to parent of the div is p2. This would be:

 //div[@id='container'][1]/parent::*/following-sibling::* 

or shorter

 //div[@id='container'][1]/../following-sibling::* 

If you are only looking for the first one extent the expression with an "predicate" (e.g [1] - for the first one. or [position() < 4]for the first three)

If your are looking for the first child of the first div:

//div[@id='container'][1]/*[1]

If there is only one div with id an you are looking for the first child:

   //div[@id='container']/*[1]

and so on.

The same answer : JOptionpane with an example :)

package experiments;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;

public class CreateDialogFromOptionPane {

    public static void main(final String[] args) {
        final JFrame parent = new JFrame();
        JButton button = new JButton();

        button.setText("Click me to show dialog!");
        parent.add(button);
        parent.pack();
        parent.setVisible(true);

        button.addActionListener(new java.awt.event.ActionListener() {
            @Override
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                String name = JOptionPane.showInputDialog(parent,
                        "What is your name?", null);
            }
        });
    }
}

>>> u"\u00b0"
u'\xb0'
>>> print _
°

BTW, all I did was search "unicode degree" on Google. This brings up two results: "Degree sign U+00B0" and "Degree Celsius U+2103", which are actually different:

>>> u"\u2103"
u'\u2103'
>>> print _
?

You must want to determine the lower and upper bound before writing the condition

function between(value,first,last) {

 let lower = Math.min(first,last) , upper = Math.max(first,last);
 return value >= lower &&  value <= upper ;

}

You are only scrolling the height of your element. offset() returns the coordinates of an element relative to the document, and top param will give you the element's distance in pixels along the y-axis:

$("html, body").animate({ scrollTop: $('#title1').offset().top }, 1000);

And you can also add a delay to it:

$("html, body").delay(2000).animate({scrollTop: $('#title1').offset().top }, 2000);

DateTime is capable of storing only two distinct times, the local time and UTC. The Kind property indicates which.

DateTimeOffset expands on this by being able to store local times from anywhere in the world. It also stores the offset between that local time and UTC. Note how DateTime cannot do this unless you'd add an extra member to your class to store that UTC offset. Or only ever work with UTC. Which in itself is a fine idea btw.

The problem with for ... in ... — and this only becomes a problem when a programmer doesn't really understand the language; it's not really a bug or anything — is that it iterates over all members of an object (well, all enumerable members, but that's a detail for now). When you want to iterate over just the indexed properties of an array, the only guaranteed way to keep things semantically consistent is to use an integer index (that is, a for (var i = 0; i < array.length; ++i) style loop).

Any object can have arbitrary properties associated with it. There would be nothing terrible about loading additional properties onto an array instance, in particular. Code that wants to see only indexed array-like properties therefore must stick to an integer index. Code that is fully aware of what for ... in does and really need to see all properties, well then that's ok too.

I faced the same issue today,

And solved it easily by following points

1) Start the StandAlone SDK manager (To open the standalone sdk manager - Tools>Android>SDKManager> at Bottom YOu will see a link to launch StandAlone SDK manager)

2) Delete tha package of SDK Build Tools that you have already installed for e.g 24.0.0 rc4.

3) Close the standalone SDK manager then Restart Android Studio.

4) Once after restart the gradle will start building the project and you will get an alert download the package of SDK build tool and Sync. CLick on that and you will start downloading like that...

I hope this helps

Stacks a considered a vertical collection. First understand that a collection is an OBJECT that gathers and organizes other smaller OBJECTS. These smaller OBJECTS are commonly referred to as Elements. These elements are "Pushed" on the stack in an A B C order where A is first and C is last. vertically it would look like this: 3rd element added) C 2nd element added) B 1st element added) A

Notice that the "A" which was first added to the stack is on the bottom. If you want to remove the "A" from the stack you first have to remove "C", then "B", and then finally your target element "A". The stack requires a LIFO approach while dealing with the complexities of a stack.(Last In First Out) When removing an element from a stack, the correct syntax is pop. we don't remove an element off a stack we "pop" it off.

Recall that "A" was the first element pushed on to the stack and "C" was the last item Pushed on the stack. Should you decide that you would like to see what is on bottom the stack, being the 3 elements are on the stack ordered A being the first B being the second and C being the third element, the top would have to be popped off then the second element added in order to view the bottom of the stack.

Try this:

!unpack file.zip

If its now working or file is 7z try below

!apt-get install p7zip-full
!p7zip -d file_name.tar.7z
!tar -xvf file_name.tar

Or

!pip install pyunpack
!pip install patool

from pyunpack import Archive
Archive(‘file_name.tar.7z’).extractall(‘path/to/’)
!tar -xvf file_name.tar

While this question is quite old I just want to add another possibility of doing a merge while keeping keys.

Besides adding key/values to existing arrays using the + sign you could do an array_replace.

$a = array('foo' => 'bar', 'some' => 'string');
$b = array(42 => 'answer to the life and everything', 1337 => 'leet');

$merged = array_replace($a, $b);

The result will be:

Array
(
  [foo] => bar
  [some] => string
  [42] => answer to the life and everything
  [1337] => leet
)

Same keys will be overwritten by the latter array.
There is also an array_replace_recursive, which do this for subarrays, too.

Live example on 3v4l.org

Just call each section of the accordion as its own accordion. active: n will be 0 for the first one( so it will display) and 1, 2, 3, 4, etc for the rest. Since each one is it's own accordion, they will all have only 1 section, and the rest will be collapsed to start.

$('.accordian').each(function(n, el) {
  $(el).accordion({
    heightStyle: 'content',
    collapsible: true,
    active: n
  });
});

I tend not to use the .on() syntax, if not necessary. For example you can migrate easier like this:

old:

$('.myButton').live('click', function);

new:

$('.myButton').click(function)

Here is a list of valid event handlers: https://api.jquery.com/category/forms/

When you call setAdapter, that does not immediately lay out and position items on the screen (that takes a single layout pass) hence your scrollToPosition() call has no actual elements to scroll to when you call it.

Instead, you should register a ViewTreeObserver.OnGlobalLayoutListener (via addOnGlobalLayoutListner() from a ViewTreeObserver created by conversationView.getViewTreeObserver()) which delays your scrollToPosition() until after the first layout pass:

conversationView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
  public void onGlobalLayout() {
    conversationView.scrollToPosition(GENERIC_MESSAGE_LIST.size();
    // Unregister the listener to only call scrollToPosition once
    conversationView.getViewTreeObserver().removeGlobalOnLayoutListener(this);

    // Use vto.removeOnGlobalLayoutListener(this) on API16+ devices as 
    // removeGlobalOnLayoutListener is deprecated.
    // They do the same thing, just a rename so your choice.
  }
});

In Chrome, go to options (Customize and Control, the 3 dots/bars at top right) ---> More Tools ---> save page as

save page as  
filename     : any_name.html 
save as type : webpage complete.

Then you will get any_name.html and any_name folder.

This is called the adjacent sibling selector, and it is represented by a plus sign...

h1.hc-reform + p {
  clear:both;
}

Note: this is not supported in IE6 or older.

Use GETDATE()

Returns the current database system timestamp as a datetime value without the database time zone offset. This value is derived from the operating system of the computer on which the instance of SQL Server is running.

UPDATE table SET date = GETDATE()

You're looking for the toggle_comment command. (Edit > Comment > Toggle Comment)

By default, this command is mapped to:

• Ctrl+/ (On Windows and Linux)
• Command ?+/ (On Mac)

This command also takes a block argument, which allows you to use block comments instead of single lines (e.g. /* ... */ as opposed to // ... in JavaScript). By default, the following key combinations are mapped to toggle block comments:

• Ctrl+Shift+/ (On Windows and Linux)
• Command ?+Alt+/ (On Mac)

Expansion for multi-dimension array total length,

Generally for your case, since the shape of the 2D array is "squared".

int length = nir.length * nir[0].length;

However, for 2D array, each row may not have the exact same number of elements. Therefore we need to traverse through each row, add number of elements up.

int length = 0;
for ( int lvl = 0; lvl < _levels.length; lvl++ )
{
    length += _levels[ lvl ].length;
}

If N-D array, which means we need N-1 for loop to get each row's size.

You can do this. It looks more wordy than a tuple, but it's a big improvement because you get type checking.

Edit: Replaced snippet with complete working example, following Nick's suggestion. Playground link: http://play.golang.org/p/RNx_otTFpk

package main

import "fmt"

func main() {
    queue := make(chan struct {string; int})
    go sendPair(queue)
    pair := <-queue
    fmt.Println(pair.string, pair.int)
}

func sendPair(queue chan struct {string; int}) {
    queue <- struct {string; int}{"http:...", 3}
}

Anonymous structs and fields are fine for quick and dirty solutions like this. For all but the simplest cases though, you'd do better to define a named struct just like you did.

I know this is an old question, but we were faced with the same problem when trying to inject Strings. So we invented a JUnit5/Mockito extension that does exactly what you want: https://github.com/exabrial/mockito-object-injection

EDIT:

@InjectionMap
 private Map<String, Object> injectionMap = new HashMap<>();

 @BeforeEach
 public void beforeEach() throws Exception {
  injectionMap.put("securityEnabled", Boolean.TRUE);
 }

 @AfterEach
 public void afterEach() throws Exception {
  injectionMap.clear();
 }

This answer is technically similar or equal to what jcoffland answered. I just added a query to detect if a script is already present or not. I need this because I work in an intranet website with a couple of modules, of which some are sharing scripts or bring their own, but these scripts do not need to be loaded everytime again. I am using this snippet since more than a year in production environment, it works like a charme. Commenting to myself: Yes I know, it would be more correct to ask if a function exists... :-)

if (!$('head > script[src="js/jquery.searchable.min.js"]').length) {
    $('head').append($('<script />').attr('src','js/jquery.searchable.min.js'));
}

I've found the solution :

You have to add the html5=1 in the src attribute of the iframe :

<iframe src="http://www.youtube.com/embed/dP15zlyra3c?html5=1"></iframe>

The video will be displayed as HTML5 if available, or fallback into flash player.

Here is a log lifecycle of each fragment in ViewPager which have 4 fragment and offscreenPageLimit = 1 (default value)

FragmentStatePagerAdapter

Go to Fragment1 (launch activity)

Fragment1: onCreateView
Fragment1: onStart
Fragment2: onCreateView
Fragment2: onStart

Go to Fragment2

Fragment3: onCreateView
Fragment3: onStart

Go to Fragment3

Fragment1: onStop
Fragment1: onDestroyView
Fragment1: onDestroy
Fragment1: onDetach
Fragment4: onCreateView
Fragment4: onStart

Go to Fragment4

Fragment2: onStop
Fragment2: onDestroyView
Fragment2: onDestroy

FragmentPagerAdapter

Go to Fragment1 (launch activity)

Fragment1: onCreateView
Fragment1: onStart
Fragment2: onCreateView
Fragment2: onStart

Go to Fragment2

Fragment3: onCreateView
Fragment3: onStart

Go to Fragment3

Fragment1: onStop
Fragment1: onDestroyView
Fragment4: onCreateView
Fragment4: onStart

Go to Fragment4

Fragment2: onStop
Fragment2: onDestroyView

Conclusion: FragmentStatePagerAdapter call onDestroy when the Fragment is overcome offscreenPageLimit while FragmentPagerAdapter not.

Note: I think we should use FragmentStatePagerAdapter for a ViewPager which have a lot of page because it will good for performance.

Example of offscreenPageLimit:

If we go to Fragment3, it will detroy Fragment1 (or Fragment5 if have) because offscreenPageLimit = 1. If we set offscreenPageLimit > 1 it will not destroy.
If in this example, we set offscreenPageLimit=4, there is no different between using FragmentStatePagerAdapter or FragmentPagerAdapter because Fragment never call onDestroyView and onDestroy when we change tab

When I accidentally switched to a guest wifi network I got this error. Had to switch back to my default wifi network.

If we declare a variable as static, there will be only one copy of the variable. So, whenever different threads access that variable, there will be only one final value for the variable(since there is only one memory location allocated for the variable).

If a variable is declared as volatile, all threads will have their own copy of the variable but the value is taken from the main memory.So, the value of the variable in all the threads will be the same.

So, in both cases, the main point is that the value of the variable is same across all threads.

The With clause would do the trick. Something like this:

WITH SELECTION AS (SELECT id FROM products LIMIT 1)
SELECT a.id, c.id, c.title FROM selection a JOIN categories c ON (c.id = a.id);

If you actually want to sort the dictionary instead of just obtaining a sorted list use collections.OrderedDict

>>> from collections import OrderedDict
>>> from operator import itemgetter
>>> data = {1: 'b', 2: 'a'}
>>> d = OrderedDict(sorted(data.items(), key=itemgetter(1)))
>>> d
OrderedDict([(2, 'a'), (1, 'b')])
>>> d.values()
['a', 'b']

This command works:

sc create startSvn binPath= "\"C:\Subversion\bin\svnserve.exe\" --service -r \"C:\SVN_Repository\"" displayname= "MyServer" depend= tcpip start= auto

First check if Git* installed or not in your system

by typing the command in cmd /command prompt (In windows)

where git

if you get an output like this

? where git
C:\cmder\vendor\git-for-windows\cmd\git.exe

Then Go to Settings > Preferences > Settings and put the bellow code** right part.

 {
    // If git enabled ?
    "git.enabled": true,

    // Path to the git executable
    "git.path": "C:\\cmder\\vendor\\git-for-windows\\cmd\\git.exe"
}

• If you don't have Git installed , Install git from here https://git-scm.com/

** Just add double slash (\\) just like the above code.

Here is a "shade" class that you can add directly to any <img> tag like so

<img src="imgs/myimg.png" class="shade">

img.shade:hover {
    -webkit-filter: brightness(85%);
    -webkit-transition: all 10ms ease;
    -moz-transition: all 10ms ease;
    -o-transition: all 10ms ease;
    -ms-transition: all 10ms ease;
    transition: all 10ms ease;
}

What you need to do is update the config.ini file for the device and re-download the system image.

Update the following values in C:\Users\USER\.android\avd\DEVICE_ID\config.ini (on Windows) or ~/.android/avd/DEVICE_ID/config.ini (on Linux)

PlayStore.enabled = true
image.sysdir.1=system-images\android-27\google_apis_playstore\x86\
tag.display=Google Play
tag.id=google_apis_playstore

Then re-download the system image for the device from Android Studio > Tools > AVD Manager

That is all. Restart your device and you'll have the Play Store installed.

This has also been answered here: How to install Google Play app in Android Studio emulator?

Well one thing you could do is if you have a switch:

switch(SomeEnum)
{
  case SomeEnum.One:
      DoThings(someUser);
      break;
  case SomeEnum.Two:
      DoSomethingElse(someUser);
      break;
}

And with the might power of actions you can turn that switch into a dictionary:

Dictionary<SomeEnum, Action<User>> methodList = 
    new Dictionary<SomeEnum, Action<User>>()

methodList.Add(SomeEnum.One, DoSomething);
methodList.Add(SomeEnum.Two, DoSomethingElse); 

...

methodList[SomeEnum](someUser);

Or you could take this farther:

SomeOtherMethod(Action<User> someMethodToUse, User someUser)
{
    someMethodToUse(someUser);
}  

....

var neededMethod = methodList[SomeEnum];
SomeOtherMethod(neededMethod, someUser);

Just a couple of examples. Of course the more obvious use would be Linq extension methods.

set scan off; Above command also works.

Why reinvent the wheel? RandomStringUtils from Apache Commons has functions to which you can specify the character set from which characters are generated. You can take what you need to your app:

http://kickjava.com/src/org/apache/commons/lang/RandomStringUtils.java.htm

From my experience with GCC I know that static and static inline differs in a way how compiler issue warnings about unused functions. More precisely when you declare static function and it isn't used in current translation unit then compiler produce warning about unused function, but you can inhibit that warning with changing it to static inline.

Thus I tend to think that static should be used in translation units and benefit from extra check compiler does to find unused functions. And static inline should be used in header files to provide functions that can be in-lined (due to absence of external linkage) without issuing warnings.

Unfortunately I cannot find any evidence for that logic. Even from GCC documentation I wasn't able to conclude that inline inhibits unused function warnings. I'd appreciate if someone will share links to description of that.

I am looking for the same problem and here is what help me. Here is the jQuery version 3.1.0 and the load event is deprecated for use since jQuery version 1.8. The load event is removed from jQuery 3.0. Instead, you can use on method and bind the JavaScript load event:

$(window).on('load', function () {
  alert("Window Loaded");
});

You can use a regular expression such as:

var x = "|f|oo||";
var y = x.replace(/^\|+|\|+$/g, "");
alert(y); // f|oo

UPDATE:

Should you wish to generalize this into a function, you can do the following:

var escapeRegExp = function(strToEscape) {
    // Escape special characters for use in a regular expression
    return strToEscape.replace(/[\-\[\]\/\{\}\(\)\*\+\?\.\\\^\$\|]/g, "\\$&");
};

var trimChar = function(origString, charToTrim) {
    charToTrim = escapeRegExp(charToTrim);
    var regEx = new RegExp("^[" + charToTrim + "]+|[" + charToTrim + "]+$", "g");
    return origString.replace(regEx, "");
};

var x = "|f|oo||";
var y = trimChar(x, "|");
alert(y); // f|oo

How to import csv file to sqlite3

1. Create database

   sqlite3 NYC.db
   

2. Set the mode & tablename

   .mode csv tripdata
   

3. Import the csv file data to sqlite3

   .import yellow_tripdata_2017-01.csv tripdata
   

4. Find tables

   .tables
   

5. Find your table schema

   .schema tripdata
   

6. Find table data

   select * from tripdata limit 10;
   

7. Count the number of rows in the table

   select count (*) from tripdata;
   

You have to free() the allocated memory in exact reverse order of how it was allocated using malloc().

Note that You should free the memory only after you are done with your usage of the allocated pointers.

memory allocation for 1D arrays:

    buffer = malloc(num_items*sizeof(double));

memory deallocation for 1D arrays:

    free(buffer);

memory allocation for 2D arrays:

    double **cross_norm=(double**)malloc(150 * sizeof(double *));
    for(i=0; i<150;i++)
    {
        cross_norm[i]=(double*)malloc(num_items*sizeof(double));
    }

memory deallocation for 2D arrays:

    for(i=0; i<150;i++)
    {
        free(cross_norm[i]);
    }

    free(cross_norm);

Your else statement should look like this (note the ^):

{{^avatar}}
 ...
{{/avatar}}

In mustache this is called 'Inverted sections'.

I would put this as a comment, but I don't have the rep for it. What Josh Crozier answered is correct, but for IE .cur and .ani are the only supported formats for this. So you should probably have a fallback just in case:

.test {
    cursor:url("http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif"), url(foo.cur), auto;
}

If you are using SQL server 2016 or higher and if your table is having partitions created based on column you are trying to delete(for example Timestamp column), then you could use this new command to delete data by partitions.

TRUNCATE TABLE WITH ( PARTITIONS ( { | } [ , ...n ] ) )

This will delete the data in selected partition(s) only and should be the most efficient way to delete data from part of table since it will not create transaction logs and will be done just as fast as regular truncate but without having all the data deleted from the table.

Drawback is if your table is not setup with partition, then you need to go old school and delete the data with regular approach and then recreate the table with partitions so that you can do this in future, which is what I did. I added the partition creation and deletion into insertion procedure itself. I had table with 500 million rows so this was the only option to reduce deletion time.

For more details refer to below links: https://docs.microsoft.com/en-us/sql/t-sql/statements/truncate-table-transact-sql?view=sql-server-2017

We all have those problems that we encounter just infrequently enough that when we see them again, we know we’ve solved this, but can’t remember how.

The NonUniqueObjectException thrown when using Session.saveOrUpdate() in Hibernate is one of mine. I’ll be adding new functionality to a complex application. All my unit tests work fine. Then in testing the UI, trying to save an object, I start getting an exception with the message “a different object with the same identifier value was already associated with the session.” Here’s some example code from Java Persistence with Hibernate.

            Session session = sessionFactory1.openSession();
            Transaction tx = session.beginTransaction();
            Item item = (Item) session.get(Item.class, new Long(1234));
            tx.commit();
            session.close(); // end of first session, item is detached

            item.getId(); // The database identity is "1234"
            item.setDescription("my new description");
            Session session2 = sessionFactory.openSession();
            Transaction tx2 = session2.beginTransaction();
            Item item2 = (Item) session2.get(Item.class, new Long(1234));
            session2.update(item); // Throws NonUniqueObjectException
            tx2.commit();
            session2.close();

To understand the cause of this exception, it’s important to understand detached objects and what happens when you call saveOrUpdate() (or just update()) on a detached object.

When we close an individual Hibernate Session, the persistent objects we are working with are detached. This means the data is still in the application’s memory, but Hibernate is no longer responsible for tracking changes to the objects.

If we then modify our detached object and want to update it, we have to reattach the object. During that reattachment process, Hibernate will check to see if there are any other copies of the same object. If it finds any, it has to tell us it doesn’t know what the “real” copy is any more. Perhaps other changes were made to those other copies that we expect to be saved, but Hibernate doesn’t know about them, because it wasn’t managing them at the time.

Rather than save possibly bad data, Hibernate tells us about the problem via the NonUniqueObjectException.

So what are we to do? In Hibernate 3, we have merge() (in Hibernate 2, use saveOrUpdateCopy()). This method will force Hibernate to copy any changes from other detached instances onto the instance you want to save, and thus merges all the changes in memory before the save.

        Session session = sessionFactory1.openSession();
        Transaction tx = session.beginTransaction();
        Item item = (Item) session.get(Item.class, new Long(1234));
        tx.commit();
        session.close(); // end of first session, item is detached

        item.getId(); // The database identity is "1234"
        item.setDescription("my new description");
        Session session2 = sessionFactory.openSession();
        Transaction tx2 = session2.beginTransaction();
        Item item2 = (Item) session2.get(Item.class, new Long(1234));
        Item item3 = session2.merge(item); // Success!
        tx2.commit();
        session2.close();

It’s important to note that merge returns a reference to the newly updated version of the instance. It isn’t reattaching item to the Session. If you test for instance equality (item == item3), you’ll find it returns false in this case. You will probably want to work with item3 from this point forward.

It’s also important to note that the Java Persistence API (JPA) doesn’t have a concept of detached and reattached objects, and uses EntityManager.persist() and EntityManager.merge().

I’ve found in general that when using Hibernate, saveOrUpdate() is usually sufficient for my needs. I usually only need to use merge when I have objects that can have references to objects of the same type. Most recently, the cause of the exception was in the code validating that the reference wasn’t recursive. I was loading the same object into my session as part of the validation, causing the error.

Where have you encountered this problem? Did merge work for you or did you need another solution? Do you prefer to always use merge, or prefer to use it only as needed for specific cases

Every action in gradle is a task, and so is test. And to exclude a task from gradle run, you can use the option --exclude-task or it's shorthand -x followed by the task name which needs to be excluded. Example:

gradle build -x test

The -x option should be repeated for all the tasks that needs to be excluded.

If you have different tasks for different type of tests in your build.gradle file, then you need to skip all those tasks that executes test. Say you have a task test which executes unit-tests and a task testFunctional which executes functional-tests. In this case, you can exclude all tests like below:

gradle build -x test -x testFunctional

Use repr:

a = "Hello\tWorld\nHello World"
print(repr(a))
# 'Hello\tWorld\nHello World'

Note you do not get \s for a space. I hope that was a typo...?

But if you really do want \s for spaces, you could do this:

print(repr(a).replace(' ',r'\s'))

In some VPS hostings (like linode) you have to click Ctrl+A and then ESC. Exit with double ESC too.

You could also try the shortKeys jQuery plugin. Usage example:

$(document).shortkeys({
  'g': function () { alert('g'); }
});

I fixed this by adding another div in the one that overflows. Then you compare the heights of the 2 divs.

<div class="AAAA overflow-hidden" style="height: 20px;" >
    <div class="BBBB" >
        Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
    </div>
</div>

and the js

    if ($('.AAAA').height() < $('.BBBB').height()) {
        console.log('we have overflow')
    } else {
        console.log('NO overflow')
    }

This looks easier...

In short:

Container is a division (virtual) in a kernel which shares a common OS and runs an image (Docker image).

A container is a self-sustainable application that will have packages and all the necessary dependencies together to run the code.

Use this XPath expression:

/*/*/X/node()

This selects any node (element, text node, comment or processing instruction) that is a child of any X element that is a grand-child of the top element of the XML document.

To verify what is selected, here is this XSLT transformation that outputs exactly the selected nodes:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>
 <xsl:template match="/">
  <xsl:copy-of select="/*/*/X/node()"/>
 </xsl:template>
</xsl:stylesheet>

and it produces exactly the wanted, correct result:

   First Text Node #1            
    <y> Y can Have Child Nodes #                
        <child> deep to it </child>
    </y>            Second Text Node #2 
    <z />

Explanation:

1. As defined in the W3 XPath 1.0 Spec, "child::node() selects all the children of the context node, whatever their node type." This means that any element, text-node, comment-node and processing-instruction node children are selected by this node-test.

2. node() is an abbreviation of child::node() (because child:: is the primary axis and is used when no axis is explicitly specified).

I'm the author of the article in question.

No doubt there are multiple ways to do it, but the way I typically do it is to implement a custom UserDetails that knows about roles and permissions. Role and Permission are just custom classes that you write. (Nothing fancy--Role has a name and a set of Permission instances, and Permission has a name.) Then the getAuthorities() returns GrantedAuthority objects that look like this:

PERM_CREATE_POST, PERM_UPDATE_POST, PERM_READ_POST

instead of returning things like

ROLE_USER, ROLE_MODERATOR

The roles are still available if your UserDetails implementation has a getRoles() method. (I recommend having one.)

Ideally you assign roles to the user and the associated permissions are filled in automatically. This would involve having a custom UserDetailsService that knows how to perform that mapping, and all it has to do is source the mapping from the database. (See the article for the schema.)

Then you can define your authorization rules in terms of permissions instead of roles.

Hope that helps.

If you have a class for each of your input box, then you can do it as

        var checked = []
        $('input.Booking').each(function ()
        {
            checked.push($(this).val());
        });

You can also use scikit-image, which provides some functions to convert an image in ndarray, like rgb2gray.

from skimage import color
from skimage import io

img = color.rgb2gray(io.imread('image.png'))

Notes: The weights used in this conversion are calibrated for contemporary CRT phosphors: Y = 0.2125 R + 0.7154 G + 0.0721 B

Alternatively, you can read image in grayscale by:

from skimage import io
img = io.imread('image.png', as_gray=True)

I have found the answer to my question.

client.DefaultRequestHeaders.Add("X-Version","1");

That should add a custom header to your request

Also, be aware of differences in casting, especially when working with bitmasks, due to casting to signed char:

bool a = 0x0100;
a == true;  // expression true

BOOL b = 0x0100;
b == false; // expression true on !((TARGET_OS_IPHONE && __LP64__) || TARGET_OS_WATCH), e.g. MacOS
b == true;  // expression true on (TARGET_OS_IPHONE && __LP64__) || TARGET_OS_WATCH

If BOOL is a signed char instead of a bool, the cast of 0x0100 to BOOL simply drops the set bit, and the resulting value is 0.

Your group statement will group by group ID. For example, if you then write:

foreach (var group in groupedCustomerList)
{
    Console.WriteLine("Group {0}", group.Key);
    foreach (var user in group)
    {
        Console.WriteLine("  {0}", user.UserName);
    }
}

that should work fine. Each group has a key, but also contains an IGrouping<TKey, TElement> which is a collection that allows you to iterate over the members of the group. As Lee mentions, you can convert each group to a list if you really want to, but if you're just going to iterate over them as per the code above, there's no real benefit in doing so.

This post already has a checked answer, but the answer doesn't filter for null values. The correct answer should prevent null values by using the Object::nonNull function as a predicate.

BigDecimal result = invoiceList.stream()
    .map(Invoice::total)
    .filter(Objects::nonNull)
    .filter(i -> (i.getUnit_price() != null) && (i.getQuantity != null))
    .reduce(BigDecimal.ZERO, BigDecimal::add);

This prevents null values from attempting to be summed as we reduce.

You should be able to declare a cursor to be a bind variable (called parameters in other DBMS')

like Vincent wrote, you can do something like this:

begin
  open :yourCursor
    for 'SELECT "'|| :someField ||'" from yourTable where x = :y'
      using :someFilterValue;
end;

You'd have to bind 3 vars to that script. An input string for "someField", a value for "someFilterValue" and an cursor for "yourCursor" which has to be declared as output var.

Unfortunately, I have no idea how you'd do that from C++. (One could say fortunately for me, though. ;-) )

Depending on which access library you use, it might be a royal pain or straight forward.

its an old question but anyway heres something i used incase someone was looking for the same thing

if (!$('#myModal').is(':visible')) {
    // if modal is not shown/visible then do something
}

Check if you have any elevation on one of the Views in XML. If so, add elevation to the other item or remove the elevation to solve the issue. From there, it's the order of the views that dictates what comes above the other.

If you are using VB, you need to drop the semicolon:

<% Response.Redirect("new.aspx", true) %>

Set a cookie:

res.cookie('cookie', 'monster')

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors at your server side.

You can fetch request using mode: 'cors'. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.

So in both condition you need to configure cors in your server or you need to use custom proxy server.

You can use imshow() method from matplotlib

import pandas as pd
import matplotlib.pyplot as plt
plt.style.use('ggplot')

plt.imshow(X.corr(), cmap=plt.cm.Reds, interpolation='nearest')
plt.colorbar()
tick_marks = [i for i in range(len(X.columns))]
plt.xticks(tick_marks, X.columns, rotation='vertical')
plt.yticks(tick_marks, X.columns)
plt.show()

This often happens when your SQL is bad (implicit type conversions etc.).

Turn on hibernate SQL logging by adding the following lines to your log4j properties file:

logs the SQL statements

log4j.logger.org.hibernate.SQL=debug

Logs the JDBC parameters passed to a query

log4j.logger.org.hibernate.type=trace

Before failing you will see the last SQL statement attempted in your log, copy and paste this SQL into an external SQL client and run it.

As you can see in the Java Source of the java.lang.String class:

/**
 * Allocates a new <code>String</code> that contains characters from
 * a subarray of the character array argument. The <code>offset</code>
 * argument is the index of the first character of the subarray and
 * the <code>count</code> argument specifies the length of the
 * subarray. The contents of the subarray are copied; subsequent
 * modification of the character array does not affect the newly
 * created string.
 *
 * @param      value    array that is the source of characters.
 * @param      offset   the initial offset.
 * @param      count    the length.
 * @exception  IndexOutOfBoundsException  if the <code>offset</code>
 *               and <code>count</code> arguments index characters outside

 */
public String(char value[], int offset, int count) {
    if (offset < 0) {
        throw new StringIndexOutOfBoundsException(offset);
    }
    if (count < 0) {
        throw new StringIndexOutOfBoundsException(count);
    }
    // Note: offset or count might be near -1>>>1.
    if (offset > value.length - count) {
        throw new StringIndexOutOfBoundsException(offset + count);
    }

    this.value = new char[count];
    this.count = count;
    System.arraycopy(value, offset, this.value, 0, count);
}

Parameter references are surrounded by <code></code> tags, which means that the Javadoc syntax does not provide any way to do such a thing. (I think String.class is a good example of javadoc usage).

Prefix the variable name with env:

$env:path

For example, if you want to print the value of environment value "MINISHIFT_USERNAME", then command will be:

$env:MINISHIFT_USERNAME

You can also enumerate all variables via the env drive:

http://blogs.msdn.com/b/peterhal/archive/2005/07/05/435760.aspx

We get a lot of requests for addditions to the C# language and today I'm going to talk about one of the more common ones - switch on type. Switch on type looks like a pretty useful and straightforward feature: Add a switch-like construct which switches on the type of the expression, rather than the value. This might look something like this:

switch typeof(e) { 
        case int:    ... break; 
        case string: ... break; 
        case double: ... break; 
        default:     ... break; 
}

This kind of statement would be extremely useful for adding virtual method like dispatch over a disjoint type hierarchy, or over a type hierarchy containing types that you don't own. Seeing an example like this, you could easily conclude that the feature would be straightforward and useful. It might even get you thinking "Why don't those #*&%$ lazy C# language designers just make my life easier and add this simple, timesaving language feature?"

Unfortunately, like many 'simple' language features, type switch is not as simple as it first appears. The troubles start when you look at a more significant, and no less important, example like this:

class C {}
interface I {}
class D : C, I {}

switch typeof(e) {
case C: … break;
case I: … break;
default: … break;
}

Data elements (e.g. members of classes and structs) are typically aligned on WORD or DWORD boundaries for current generation processors in order to improve access times. Retrieving a DWORD at an address which isn't divisible by 4 requires at least one extra CPU cycle on a 32 bit processor. So, if you have e.g. three char members char a, b, c;, they actually tend to take 6 or 12 bytes of storage.

#pragma allows you to override this to achieve more efficient space usage, at the expense of access speed, or for consistency of stored data between different compiler targets. I had a lot of fun with this transitioning from 16 bit to 32 bit code; I expect porting to 64 bit code will cause the same kinds of headaches for some code.

For the best practice - use style="display:"

it will work every where..

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

You can use serializeArray ^[docs] and add the additional data:

var data = $('#myForm').serializeArray();
data.push({name: 'wordlist', value: wordlist});

$.post("page.php", data);

Spring has a built in BeanUtils.copyProperties method. But it doesn't work with classes without getters/setters. JSON serialization/deserialization can be another option for copying fields. Jackson can be used for this purpose. If you are using Spring In most cases Jackson is already in your dependency list.

ObjectMapper mapper     = new ObjectMapper().configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
Clazz        copyObject = mapper.readValue(mapper.writeValueAsString(sourceObject), Clazz.class);

By default setTextSize, without units work in SP (scales pixel)

public void setTextSize (float size) 
Added in API level 1
Set the default text size to the given value, interpreted as "scaled pixel" units. This 
size is adjusted based on the current density and user font size preference.

It fails "when trying to execute the function manually" because you have a different 'this'. This will refer not to the thing you have in mind when invoking the method manually, but something else, probably the window object, or whatever context object you have when invoking manually.

You can find some demos and plugins here.

You can do the folllwoing: import the jar file inside you class:

import javax.servlet.http.HttpServletResponse

add the Apache Tomcat library as follow:

Project > Properties > Java Build Path > Libraries > Add library from library tab > Choose server runtime > Next > choose Apache Tomcat v 6.0 > Finish > Ok

Also First of all, make sure that Servlet jar is included in your class path in eclipse as PermGenError said.

I think this will solve your error

In addition to the answer
1. Open POSTMAN
2. Click on "import" tab on the upper left side.
3. Select the Raw Text option and paste your cURL command.
4. Hit import and you will have the command in your Postman builder!
5. If -u admin:admin are not imported, just go to the Authorization 
   tab, select Basic Auth -> enter the user name eg admin and password eg admin.
This will automatically generate Authorization header based on Base64 encoder

There should be svn utility on you box, if installed:

$ svn checkout http://example.com/svn/somerepo somerepo

This will check out a working copy from a specified repository to a directory somerepo on our file system.

You may want to print commands, supported by this utility:

$ svn help

uname -a output in your question is identical to one, used by Parallels Virtuozzo Containers for Linux 4.0 kernel, which is based on Red Hat 5 kernel, thus your friends are rpm or the following command:

$ sudo yum install subversion

For example string s="(U+007c)"

To remove only the parentheses from s, try the below one:

import re
a=re.sub("\\(","",s)
b=re.sub("\\)","",a)
print(b)

Gradle cache is located at

• On Windows: %USERPROFILE%\.gradle\caches
• On Mac / UNIX: ~/.gradle/caches/

You can browse to these directory and manually delete it or run

rm -rf $HOME/.gradle/caches/

on UNIX system. Run this command will also force to download dependencies.

UPDATE

Clear the Android build cache of current project

NOTE: Android Studio's File > Invalidate Caches / Restart doesn't clear the Android build cache, so you'll have to clean it separately.

On Windows:

gradlew cleanBuildCache

On Mac or UNIX:

./gradlew cleanBuildCache

If you are using the glyphicon as the first character of the string, you can use the html char (see https://glyphicons.bootstrapcheatsheets.com/) and then apply the font to the first character of the element:

    option::first-letter{
        font-family: Glyphicons Halflings;
    }

Why not

DELETE FROM table ORDER BY id DESC LIMIT 1, 123456789

Just delete all but the first row (order is DESC!), using a very very large nummber as second LIMIT-argument. See here

For fields where NULL is acceptable, you could use var_export($var, true) to output the string, integer, or NULL literal. Note that you would not surround the output with quotes because they will be automatically added or omitted.

For example:

mysql_query("insert into table2 (f1, f2) values ('{$row['string_field']}', ".var_export($row['null_field'], true).")");

You can loop through each the cells in your range and use the InStr function to check if a cell contains a string, in your case; a hyphen.

Sub DeleteRowsWithHyphen()

    Dim rng As Range

    For Each rng In Range("A2:A10") 'Range of values to loop through

        If InStr(1, rng.Value, "-") > 0 Then 'InStr returns an integer of the position, if above 0 - It contains the string
            rng.Delete
        End If

    Next rng

End Sub

Like this:

function createJSON() {
    jsonObj = [];
    $("input[class=email]").each(function() {

        var id = $(this).attr("title");
        var email = $(this).val();

        item = {}
        item ["title"] = id;
        item ["email"] = email;

        jsonObj.push(item);
    });

    console.log(jsonObj);
}

Explanation

You are looking for an array of objects. So, you create a blank array. Create an object for each input by using 'title' and 'email' as keys. Then you add each of the objects to the array.

If you need a string, then do

jsonString = JSON.stringify(jsonObj);

Sample Output

[{"title":"QA","email":"a@b"},{"title":"PROD","email":"b@c"},{"title":"DEV","email":"c@d"}] 

Better to use independent code.....

var xhrQueue = []; 

$(document).ajaxSend(function(event,jqxhr,settings){
    xhrQueue.push(jqxhr); //alert(settings.url);
});

$(document).ajaxComplete(function(event,jqxhr,settings){
    var i;   
    if((i=$.inArray(jqxhr,xhrQueue)) > -1){
        xhrQueue.splice(i,1); //alert("C:"+settings.url);
    }
});

ajaxAbort = function (){  //alert("abortStart");
    var i=0;
    while(xhrQueue.length){ 
        xhrQueue[i++] .abort(); //alert(i+":"+xhrQueue[i++]);
    }
};

AngularJS is doing it right as it doing the following content-type inside the http-request header:

Content-Type: application/json

If you are going with php like me, or even with Symfony2 you can simply extend your server compatibility for the json standard like described here: http://silex.sensiolabs.org/doc/cookbook/json_request_body.html

The Symfony2 way (e.g. inside your DefaultController):

$request = $this->getRequest();
if (0 === strpos($request->headers->get('Content-Type'), 'application/json')) {
    $data = json_decode($request->getContent(), true);
    $request->request->replace(is_array($data) ? $data : array());
}
var_dump($request->request->all());

The advantage would be, that you dont need to use jQuery param and you could use AngularJS its native way of doing such requests.

I think that it's because the locale is hardcoded into the DatePipe. See this link:

• https://github.com/angular/angular/blob/master/modules/%40angular/common/src/pipes/date_pipe.ts

And there is no way to update this locale by configuration right now.

Why not use nautilus the default file manager in gnome? Here is how you may -
Best SCP GUI on Linux

As Yoni already mentioned, you probably deleted the project named "Servers" from your Project Explorer. If config files for the server still present on a file system, the quickest way to restore it will be Right Click in Project Explorer->Import->General->Existing Projects into Workspace, then select the root dir where Servers dir located, set checkbox near "Servers" and finally click Finish. If everything works as expected, you should see the 'Servers' project added to the Project Explorer view and your old config files will be there. Finally, save the tomcat configuration which you had open. You can startup your Tomcat server without errors now.

Very close! In your select expression, you have to use a pipe (|) before contains.

This filter produces the expected output.

. - map(select(.Names[] | contains ("data"))) | .[] .Id

The jq Cookbook has an example of the syntax.

Filter objects based on the contents of a key

E.g., I only want objects whose genre key contains "house".

$ json='[{"genre":"deep house"}, {"genre": "progressive house"}, {"genre": "dubstep"}]'
$ echo "$json" | jq -c '.[] | select(.genre | contains("house"))'
{"genre":"deep house"}
{"genre":"progressive house"}

Colin D asks how to preserve the JSON structure of the array, so that the final output is a single JSON array rather than a stream of JSON objects.

The simplest way is to wrap the whole expression in an array constructor:

$ echo "$json" | jq -c '[ .[] | select( .genre | contains("house")) ]'
[{"genre":"deep house"},{"genre":"progressive house"}]

You can also use the map function:

$ echo "$json" | jq -c 'map(select(.genre | contains("house")))'
[{"genre":"deep house"},{"genre":"progressive house"}]

map unpacks the input array, applies the filter to every element, and creates a new array. In other words, map(f) is equivalent to [.[]|f].

To be relative to the root directory, just start the URI with a /

<link type="text/css" rel="stylesheet" href="/style.css" />
<script src="/script.js" type="text/javascript"></script>

struct ScreenSize {
    static let width = UIScreen.main.bounds.size.width
    static let height = UIScreen.main.bounds.size.height
    static let maxLength = max(ScreenSize.width, ScreenSize.height)
    static let minLength = min(ScreenSize.width, ScreenSize.height)
    static let frame = CGRect(x: 0, y: 0, width: ScreenSize.width, height: ScreenSize.height)
}

struct DeviceType {
    static let iPhone4orLess = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.maxLength < 568.0
    static let iPhone5orSE = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.maxLength == 568.0
    static let iPhone678 = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.maxLength == 667.0
    static let iPhone678p = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.maxLength == 736.0
    static let iPhoneX = UIDevice.current.userInterfaceIdiom == .phone && ScreenSize.maxLength == 812.0

    static let IS_IPAD              = UIDevice.current.userInterfaceIdiom == .pad && ScreenSize.maxLength == 1024.0
    static let IS_IPAD_PRO          = UIDevice.current.userInterfaceIdiom == .pad && ScreenSize.maxLength == 1366.0
}

Using this function you can get Image Bitmap. Just pass image url

 public Bitmap getBitmapFromURL(String strURL) {
      try {
        URL url = new URL(strURL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
      } catch (IOException e) {
        e.printStackTrace();
        return null;
      }
 }

To get a deterministic value for the day of week for a given date you could use a combination of DATEPART() and @@datefirst. Otherwise your dependent on the settings on the server.

Check out the following site for a better solution: MS SQL: Day of Week

The day of week will then be in the range 0 to 6, where 0 is Sunday, 1 is Monday, etc. Then you can use a simple case statement to return the correct weekday name.

Given an array you can use the Array.ConvertAll method:

int[] myInts = Array.ConvertAll(arr, s => int.Parse(s));

Thanks to Marc Gravell for pointing out that the lambda can be omitted, yielding a shorter version shown below:

int[] myInts = Array.ConvertAll(arr, int.Parse);

A LINQ solution is similar, except you would need the extra ToArray call to get an array:

int[] myInts = arr.Select(int.Parse).ToArray();

If I understand you correctly, you need to use -SearchBase:

Get-ADUser -SearchBase "OU=Accounts,OU=RootOU,DC=ChildDomain,DC=RootDomain,DC=com" -Filter *

Note that Get-ADUser defaults to using

 -SearchScope Subtree

so you don't need to specify it. It's this that gives you all sub-OUs (and sub-sub-OUs, etc.).

Since you've asked to read and modify the xls file I have changed @mj82's answer to correspond your needs.

HSSFWorkbook does not have Save method, but it does have Write to a stream.

static void Main(string[] args)
        {
            string filepath = @"C:\test.xls";

            HSSFWorkbook hssfwb;

            using (FileStream file = new FileStream(filepath, FileMode.Open, FileAccess.Read))
            {
                hssfwb = new HSSFWorkbook(file);
            }

            ISheet sheet = hssfwb.GetSheetAt(0);

            for (int row = 0; row <= sheet.LastRowNum; row++)
            {
                if (sheet.GetRow(row) != null) //null is when the row only contains empty cells

                    // Set new cell value
                    sheet.GetRow(row).GetCell(0).SetCellValue("foo");
                    Console.WriteLine("Row {0} = {1}", row, sheet.GetRow(row).GetCell(0).StringCellValue);
                }
            }

            // Save the file
            using (FileStream file = new FileStream(filepath, FileMode.Open, FileAccess.Write))
            {
                hssfwb.Write(file);

It would appear that the ADB daemon on the device (adbd) is disagreeing with the ADB server process on your host computer as to which version of the protocol they are speaking. Which version of the SDK are you running and what is the OS version on the device you are debugging?

What you might need to do is actually downgrade your version of the SDK tools so that the ADB daemon and process are in agreement. I thought the server process was completely backward compatible, but this could be one of those corner cases where it doesn't. Google doesn't advertise the fact that you can get their old SDK tools packages, but they can be found by looking in the archives area at http://developer.android.com.

Tkinter is a GUI module for python. you can use it to make GUI based applications in python. Tkinter provides several GUI widgets like buttons,menu, canvas,text,frame,label etc. to develop desktop applications.Though Tkinter is very popular and is included with windows, macosx install of python, There are also alternative choices like pyQt, wxPython...

In this tutorial we will see how to install it on linux and use it with an example.

First, check if you have python installed and also check its version

Open up your terminal and type python. if its installed then it will show information like version, help... check your version (mine is python 2.7.9)

aman@vostro:~$ python Python 2.7.9 (default, Apr 2 2015, 15:33:21) [GCC 4.9.2] on linux2 Type "help", "copyright", "credits" or "license" for more information.

If you don't have python then install it sudo apt-get install python

If you want to install python 3 then enter the following. If you are a newbie, I would recommend python 2 instead of python 3. Python 2 is still very popular and many apps are made on it. On ubuntu python2 is still the default sudo apt-get install python3

Finally, Install Tkinter

sudo apt-get install python-tk

for python 3

sudo apt-get install python3-tk

How to Use it

Now, lets check if Tkinter is working well with this little example

open your terminal and enter into your python shell. python

for python3 python3

if python was installed correctly you will get a >>> prompt. aman@vostro:~$ python

Python 2.7.9 (default, Apr  2 2015, 15:33:21)
[GCC 4.9.2] on linux2

Type "help", "copyright", "credits" or "license" for more information.
>>>

Now import Tkinter module. it wont show any error if it got imported correctly. NOTE: Make sure you type Tkinter (not tkinter) in python2 and tkinter (not Tkinter) in python3.

>>>import Tkinter

Now, just to check you can create an empty window using Tkinter.

>>>Tkinter.Tk()

The ultimate solution would be setting overflow: hidden; on document.documentElement like so:

/* element is an HTML element You want catch the touch */
element.addEventListener('touchstart', function(e) {
    document.documentElement.style.overflow = 'hidden';
});

document.addEventListener('touchend', function(e) {
    document.documentElement.style.overflow = 'auto';
});

By setting overflow: hidden on start of touch it makes everything exceeding window hidden thus removing availability to scroll anything (no content to scroll).

After touchend the lock can be freed by setting overflow to auto (the default value).

It is better to append this to <html> because <body> may be used to do some styling, plus it can make children behave unexpectedly.

EDIT: About touch-action: none; - Safari doesn't support it according to MDN.

It is also interesting to compare the file of the current working revision with the same file of another revision.

You can do as follows:

$ svn diff -r34 file

I would like to add to the answer provided by Sangam Belose. Here's his code:

select ('id') as id, ('time') as time, ('unit') as unit
UNION ALL
SELECT * INTO OUTFILE 'C:/Users/User/Downloads/data.csv'
  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
  LINES TERMINATED BY '\n'
  FROM sensor

However, if you have not set up your "secure_file_priv" within the variables, it may not work. For that, check the folder set on that variable by:

SHOW VARIABLES LIKE "secure_file_priv"

The output should look like this:

mysql> show variables like "%secure_file_priv%";
+------------------+------------------------------------------------+
| Variable_name    | Value                                          |
+------------------+------------------------------------------------+
| secure_file_priv | C:\ProgramData\MySQL\MySQL Server 8.0\Uploads\ |
+------------------+------------------------------------------------+
1 row in set, 1 warning (0.00 sec)

You can either change this variable or change the query to output the file to the default path showing.

These three line all together worked for me.

background-image: url("pages/images/backImage.png");
background-size: 100%;
background-repeat: no-repeat;

I sorted this problem by verifying the json on JSONLint.com and then using Jackson. Below is the code for the same.

 Main Class:-

String jsonStr = "[{\r\n" + "       \"name\": \"John\",\r\n" + "        \"city\": \"Berlin\",\r\n"
                + "         \"cars\": [\r\n" + "            \"FIAT\",\r\n" + "          \"Toyata\"\r\n"
                + "     ],\r\n" + "     \"job\": \"Teacher\"\r\n" + "   },\r\n" + " {\r\n"
                + "     \"name\": \"Mark\",\r\n" + "        \"city\": \"Oslo\",\r\n" + "        \"cars\": [\r\n"
                + "         \"VW\",\r\n" + "            \"Toyata\"\r\n" + "     ],\r\n"
                + "     \"job\": \"Doctor\"\r\n" + "    }\r\n" + "]";

        ObjectMapper mapper = new ObjectMapper();

        MyPojo jsonObj[] = mapper.readValue(jsonStr, MyPojo[].class);

        for (MyPojo itr : jsonObj) {

            System.out.println("Val of getName is: " + itr.getName());
            System.out.println("Val of getCity is: " + itr.getCity());
            System.out.println("Val of getJob is: " + itr.getJob());
            System.out.println("Val of getCars is: " + itr.getCars() + "\n");

        }

POJO:

public class MyPojo {

private List<String> cars = new ArrayList<String>();

private String name;

private String job;

private String city;

public List<String> getCars() {
    return cars;
}

public void setCars(List<String> cars) {
    this.cars = cars;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getJob() {
    return job;
}

public void setJob(String job) {
    this.job = job;
}

public String getCity() {
    return city;
}

public void setCity(String city) {
    this.city = city;
} }

  RESULT:-
         Val of getName is: John
         Val of getCity is: Berlin
         Val of getJob is: Teacher
         Val of getCars is: [FIAT, Toyata]

          Val of getName is: Mark
          Val of getCity is: Oslo
          Val of getJob is: Doctor
          Val of getCars is: [VW, Toyata]

Here how I solved it using Cookies:

First of all, inside the website main script:

var browserWindowSize = getCookie("_browserWindowSize");
var newSize = $(window).width() + "," + $(window).height();
var reloadForCookieRefresh = false;

if (browserWindowSize == undefined || browserWindowSize == null || newSize != browserWindowSize) {
    setCookie("_browserWindowSize", newSize, 30);
    reloadForCookieRefresh = true;
}

if (reloadForCookieRefresh)
    window.location.reload();

function setCookie(name, value, days) {
    var expires = "";
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        expires = "; expires=" + date.toUTCString();
    }
    document.cookie = name + "=" + (value || "") + expires + "; path=/";
}

function getCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1, c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
    }
    return null;
}

And inside MVC action filter:

public class SetCurrentRequestDataFilter : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // currentRequestService is registered per web request using IoC
        var currentRequestService = iocResolver.Resolve<ICurrentRequestService>();

        if (filterContext.HttpContext.Request.Cookies.AllKeys.Contains("_browserWindowSize"))
        {
            var browserWindowSize = filterContext.HttpContext.Request.Cookies.Get("_browserWindowSize").Value.Split(',');
            currentRequestService.browserWindowWidth = int.Parse(browserWindowSize[0]);
            currentRequestService.browserWindowHeight = int.Parse(browserWindowSize[1]);
        }

    }
}

In cordova 3.3.1-0.1.2 the expected behavior is not working right.

in

http://cordova.apache.org/docs/en/3.3.0/config_ref_images.md.html#Icons%20and%20Splash%20Screens

it clearly states you're suppose to put them into your main www folder in a folder called res and icons that follow a particular naming convention instead of the original customizable config.xml specified way (in which you point to a file of your choosing, which was/is much better). it should take then from there for each platform and put them into the platforms/?android?/res/drawable-?dpi/icon.png but it does no such correct behavior at this time... bug.

so I guess we have to manually put them there for each platform. it would of course need to remove that from duplicating it into the www folder again. for me I had to totally replace the contents in the main www folder anyway because it simply didn't work with even hello world without hacking a redirect index.html to find some weird random folder there. Putting the res folder beside www makes the most sense but what ever it seems to be for me caused by this series of cascading and confusing design choices/flaws.

I woudn't bother with the likelihood of collision. Just generate a random string and check if it exists. If it does, try again and you shouldn't need to do it more that a couple of times unless you have a huge number of plates already assigned.

Another solution for generating an 8-character long pseudo-random string in pure (My)SQL:

SELECT LEFT(UUID(), 8);

You can try the following (pseudo-code):

DO 
    SELECT LEFT(UUID(), 8) INTO @plate;
    INSERT INTO plates (@plate);
WHILE there_is_a_unique_constraint_violation
-- @plate is your newly assigned plate number

Since this post has received a unexpected level of attention, let me highlight ADTC's comment : the above piece of code is quite dumb and produces sequential digits.

For slightly less stupid randomness try something like this instead :

SELECT LEFT(MD5(RAND()), 8)

And for true (cryptograpically secure) randomness, use RANDOM_BYTES() rather than RAND() (but then I would consider moving this logic up to the application layer).

- (void) imageConvert
{
     UIImage *snapshot = self.myImageView.image;
     [self encodeImageToBase64String:snapshot];
}    


call this method for image convert in base 64 
    -(NSString *)encodeImageToBase64String:(UIImage *)image
    {
        return [UIImagePNGRepresentation(image) base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
    }

Maybe you can wrap the PowerShell invocation in a .bat file like so:

rem ps.bat
@echo off
powershell.exe -command "%*"

If you then placed this file under a folder in your PATH, you could call PowerShell scripts like this:

ps foo 1 2 3

Quoting can get a little messy, though:

ps write-host """hello from cmd!""" -foregroundcolor green

that scp command must be issued on the local command-line, for putty the command is pscp.

C:\something> pscp [email protected]:/dir/of/file.txt \local\dir\

This should work...tested on a mac...

#include <stdio.h>
#include <sys/time.h>

int main() {
        struct timeval tv;
        struct timezone tz;
        struct tm *tm;
        gettimeofday(&tv,&tz);
        tm=localtime(&tv.tv_sec);
        printf("StartTime: %d:%02d:%02d %d \n", tm->tm_hour, tm->tm_min, tm->tm_sec, tv.tv_usec);
}

Yeah...run it twice and subtract...

I am adding this A because I got caught with a bizarre version of this which really had me scratching my head for about a hour until I spotted the root cause. My load was failing because of multiple repeats of this format

<path>/linit.o:(.rodata1.libs+0x50): multiple definition of `lua_lib_BASE'
<path>/linit.o:(.rodata1.libs+0x50): first defined here

I turned out to be a bug in my Makefile magic where I had a list of C files and using vpath etc., so the compiles would pick them up from the correct directory in hierarchy. However one C file was repeated in the list, at the end of one line and the start of the next so the gcc load generated by the make had the .o file twice on the command line. Durrrrh. The multiple definitions were from multiple occurances of the same file. The linker ignored duplicates apart from static initialisers!

You can try cactoos for that.

final InputStream input = new InputStreamOf("example");

The object is created with new and not a static method for a reason.

You can set height and width like this:

myGraphView.setLayoutParams(new LayoutParams(width, height));

Today I filed a JEP draft to OpenJDK about this aliasing feature. I hope they will reconsider it.

If you are interested, you can find a JEP draft here: https://gist.github.com/cardil/b29a81efd64a09585076fe00e3d34de7

Collection.contains() is implemented by calling equals() on each object until one returns true.

So one way to implement this is to override equals() but of course, you can only have one equals.

Frameworks like Guava therefore use predicates for this. With Iterables.find(list, predicate), you can search for arbitrary fields by putting the test into the predicate.

Other languages built on top of the VM have this built in. In Groovy, for example, you simply write:

def result = list.find{ it.name == 'John' }

Java 8 made all our lives easier, too:

List<Foo> result = list.stream()
    .filter(it -> "John".equals(it.getName())
    .collect(Collectors.toList());

If you care about things like this, I suggest the book "Beyond Java". It contains many examples for the numerous shortcomings of Java and how other languages do better.

I fixed mine. The fb sdk downloaded (from my browser) as 'FacebookSDKs-iOS-4.22.0' -- I just had to rename the folder to FacebookSDK. So now in Build

Settings --> Framework Search Paths

the path looks something like /Users/.../Documents/FacebookSDK (where as before it was /Users/.../Documents/FacebookSDKs-iOS-4.22.0) Hope this helps!?

JLS Standard

JLS 7 15.17.2. Division Operator / says:

Integer division rounds toward 0. That is, the quotient produced for operands n and d that are integers after binary numeric promotion (§5.6.2) is an integer value q whose magnitude is as large as possible while satisfying |d · q| = |n|. Moreover, q is positive when |n| = |d| and n and d have the same sign, but q is negative when |n| = |d| and n and d have opposite signs.

This is why 1/2 does not give a float.

Converting just either one to float as in (float)1/2 suffices because 15.17. Multiplicative Operators says:

Binary numeric promotion is performed on the operands

and 5.6.2. Binary Numeric Promotion says:

• If either operand is of type double, the other is converted to double.
• Otherwise, if either operand is of type float, the other is converted to float

This isn't a "slice", but it is a general solution that doesn't use explicit indexing, and works for the scenario where the sequence in question is anonymous (so you can create and "slice" on the same line, without creating twice and indexing twice): operator.itemgetter

import operator

# Done once and reused
first_and_last = operator.itemgetter(0, -1)

...

first, last = first_and_last(some_list)

You could just inline it as (after from operator import itemgetter for brevity at time of use):

first, last = itemgetter(0, -1)(some_list)

but if you'll be reusing the getter a lot, you can save the work of recreating it (and give it a useful, self-documenting name) by creating it once ahead of time.

Thus, for your specific use case, you can replace:

x, y = a.split("-")[0], a.split("-")[-1]

with:

x, y = itemgetter(0, -1)(a.split("-"))

and split only once without storing the complete list in a persistent name for len checking or double-indexing or the like.

Note that itemgetter for multiple items returns a tuple, not a list, so if you're not just unpacking it to specific names, and need a true list, you'd have to wrap the call in the list constructor.

SimpleDateFormat sdf = new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss" );
// or SimpleDateFormat sdf = new SimpleDateFormat( "MM/dd/yyyy KK:mm:ss a Z" );
sdf.setTimeZone( TimeZone.getTimeZone( "UTC" ) );
System.out.println( sdf.format( new Date() ) );

The real problem here is that there is a bug in hibernate where it uses select-list aliases in the where-clause:

http://opensource.atlassian.com/projects/hibernate/browse/HHH-817

Just in case someone lands here looking for answers, go look at the ticket. It took 5 years to fix but in theory it'll be in one of the next releases and then I suspect your issue will go away.

There is a type of constraint which breaks the scroll function:

Just make sure you are not using this constraint on any view when wanting your ConstraintLayout to be scrollable with ScrollView :

app:layout_constraintBottom_toBottomOf=“parent”

If you remove these your scroll should work.

Explanation:

Setting the height of the child to match that of a ScrollView parent is contradictory to what the component is meant to do. What we want most of the time is for some dynamic sized content to be scrollable when it is larger than a screen/frame; matching the height with the parent ScrollView would force all the content to be displayed into a fixed frame (the height of the parent) hence invalidating any scrolling functionality.

This also happens when regular direct child components are set to layout_height="match_parent".

If you want the child of the ScrollView to match the height of the parent when there is not enough content, simply set android:fillViewport to true for the ScrollView.

providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")

This should be

compile("org.springframework.boot:spring-boot-starter-tomcat")

If you are using terminal(ssh or something) and you want to keep a long-time script working after you log out from the terminal, you can try this:

screen

apt-get install screen

create a virtual terminal inside( namely abc): screen -dmS abc

now we connect to abc: screen -r abc

So, now we can run python script: python keep_sending_mails.py

from now on, you can directly close your terminal, however, the python script will keep running rather than being shut down

Since this keep_sending_mails.py's PID is a child process of the virtual screen rather than the terminal(ssh)

If you want to go back check your script running status, you can use screen -r abc again

Here's how I do it:

new WebDriverWait(driver, 20).until(
       ExpectedConditions.jsReturnsValue(
                   "return document.readyState === 'complete' ? true : false"));
