This could be your connectors for MySQL which need to be updated, as MySQL8 changed the encryption of passwords - so older connectors are encrypting them incorrectly.

The maven repo for the java connector can be found here.
If you use flyway plugin, you should also consider updating it, too!

Then you can simply update your maven pom with:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.17</version>
</dependency>

Or for others who use Gradle, you can update build.gradle with:

 buildscript {
    ext {
        ...
    }
    repositories {
        ...
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath('mysql:mysql-connector-java:8.0.11')
    }
 }

I faced similar issue "CrashLoopBackOff" when I debugged getting pods and logs of pod. Found out that my command arguments are wrong

Claiming that the C++ compiler can produce more optimal code than a competent assembly language programmer is a very bad mistake. And especially in this case. The human always can make the code better than the compiler can, and this particular situation is a good illustration of this claim.

The timing difference you're seeing is because the assembly code in the question is very far from optimal in the inner loops.

(The below code is 32-bit, but can be easily converted to 64-bit)

For example, the sequence function can be optimized to only 5 instructions:

    .seq:
        inc     esi                 ; counter
        lea     edx, [3*eax+1]      ; edx = 3*n+1
        shr     eax, 1              ; eax = n/2
        cmovc   eax, edx            ; if CF eax = edx
        jnz     .seq                ; jmp if n<>1

The whole code looks like:

include "%lib%/freshlib.inc"
@BinaryType console, compact
options.DebugMode = 1
include "%lib%/freshlib.asm"

start:
        InitializeAll
        mov ecx, 999999
        xor edi, edi        ; max
        xor ebx, ebx        ; max i

    .main_loop:

        xor     esi, esi
        mov     eax, ecx

    .seq:
        inc     esi                 ; counter
        lea     edx, [3*eax+1]      ; edx = 3*n+1
        shr     eax, 1              ; eax = n/2
        cmovc   eax, edx            ; if CF eax = edx
        jnz     .seq                ; jmp if n<>1

        cmp     edi, esi
        cmovb   edi, esi
        cmovb   ebx, ecx

        dec     ecx
        jnz     .main_loop

        OutputValue "Max sequence: ", edi, 10, -1
        OutputValue "Max index: ", ebx, 10, -1

        FinalizeAll
        stdcall TerminateAll, 0

In order to compile this code, FreshLib is needed.

In my tests, (1 GHz AMD A4-1200 processor), the above code is approximately four times faster than the C++ code from the question (when compiled with -O0: 430 ms vs. 1900 ms), and more than two times faster (430 ms vs. 830 ms) when the C++ code is compiled with -O3.

The output of both programs is the same: max sequence = 525 on i = 837799.

To add an exclusion for logback from Netbeans IDE

1. Access the >Projects explorer section for your project
2. Proceed to >Dependencies as displayed below
3. Trace 'spring-boot-starter-logging-X.X.X.jar'

4. Right click on the jar and select Exclude Dependency as shown below. This excludes the logback jar on the pom.xml like this;

     <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
       <exclusions>
           <exclusion>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-starter-logging</artifactId>
           </exclusion>
       </exclusions>
   </dependency>
   

Adding the spring boot starter dependency fixed my error.

This is required if you want to start the tomcat as an embeded server.

Had been over looking the issue having surfaced it. Believe this will be a good read for others who come down here with the same issue:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=387064

I answer this coming from a component-based architecture, where an organisation may be running many components that may rely on each other. During a propagating failure, logging levels should help to identify both which components are affected and which are a root cause.

• ERROR - This component has had a failure and the cause is believed to be internal (any internal, unhandled exception, failure of encapsulated dependency... e.g. database, REST example would be it has received a 4xx error from a dependency). Get me (maintainer of this component) out of bed.

• WARN - This component has had a failure believed to be caused by a dependent component (REST example would be a 5xx status from a dependency). Get the maintainers of THAT component out of bed.

• INFO - Anything else that we want to get to an operator. If you decide to log happy paths then I recommend limiting to 1 log message per significant operation (e.g. per incoming http request).

For all log messages be sure to log useful context (and prioritise on making messages human readable/useful rather than having reams of "error codes")

• DEBUG (and below) - Shouldn't be used at all (and certainly not in production). In development I would advise using a combination of TDD and Debugging (where necessary) as opposed to polluting code with log statements. In production, the above INFO logging, combined with other metrics should be sufficient.

A nice way to visualise the above logging levels is to imagine a set of monitoring screens for each component. When all running well they are green, if a component logs a WARNING then it will go orange (amber) if anything logs an ERROR then it will go red.

In the event of an incident you should have one (root cause) component go red and all the affected components should go orange/amber.

I take no credit for this answer, as it's merely a combination of the best two answers above: that of X. Wo Satuk and that of Sébastien Helbert: ThresholdFilter is lovely but you can't configure it to have an upper level as well as a lower level*, but combining it with two LevelFilters set to "DENY" WARN and ERROR works a treat.

Very important: do not forget the <target>System.err</target> tag in the STDERR appender: my omission of it had me frustrated for a few minutes.

* it does however have a method decide in the API but I haven't a clue how you'd use it in this context.

I seem to be having success doing

org.jboss.logmanager.Logger logger = org.jboss.logmanager.Logger.getLogger("");
logger.setLevel(java.util.logging.Level.ALL);

Then to get detailed logging from netty, the following has done it

org.slf4j.impl.SimpleLogger.setLevel(org.slf4j.impl.SimpleLogger.TRACE);

Just to help those in a similar situation to myself...

This can be caused when a dependent library has accidentally bundled an old version of slf4j. In my case, it was tika-0.8. See https://issues.apache.org/jira/browse/TIKA-556

The workaround is exclude the component and then manually depends on the correct, or patched version.

EG.

<dependency>
    <groupId>org.apache.tika</groupId>
    <artifactId>tika-parsers</artifactId>
    <version>0.8</version>
    <exclusions>
        <exclusion>
            <!-- NOTE: Version 4.2 has bundled slf4j -->
            <groupId>edu.ucar</groupId>
            <artifactId>netcdf</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <!-- Patched version 4.2-min does not bundle slf4j -->
    <groupId>edu.ucar</groupId>
    <artifactId>netcdf</artifactId>
    <version>4.2-min</version>

Try the jEscape plugin (download from google drive)

$(document).escape(function() { 
   alert('ESC button pressed'); 
});

or get keycode for cross browser

var code = (e.keyCode ? e.keyCode : e.which);
if (code === 27) alert('ESC');
if (code === 13) alert('ENTER');

maybe you can use switch

var code = (e.keyCode ? e.keyCode : e.which);
switch (code) {
    case 27:
       alert('ESC');
       break;
     case 13:
       alert('ENTER');
       break;
}

I am amazed to see so many string replace ideas of UUID. How about this:

UUID temp = UUID.randomUUID();
String uuidString = Long.toHexString(temp.getMostSignificantBits())
     + Long.toHexString(temp.getLeastSignificantBits());

This is the fasted way of doing it since the whole toString() of UUID is already more expensive not to mention the regular expression which has to be parsed and executed or the replacing with empty string.

I found a very simple solution for Firefox (only works with a relative rather than a direct href): add type="application/octet-stream":

<a href="./file.pdf" id='example' type="application/octet-stream">Example</a>

We are using akka with its camel plugin to distribute our analysis and trending processing for twimpact.com. We have to process between 50 and 1000 messages per second. In addition to multi-node processing with camel it is also used to distribute work on a single processor to multiple workers for maximum performance. Works quite well, but requires some understanding of how to handle congestions.

Here's my go:

UPDATE test as t1 
    INNER JOIN test as t2 ON 
        t1.NAME = t2.NAME AND 
        t2.value IS NOT NULL 
SET t1.VALUE = t2.VALUE;

EDIT: Removed superfluous t1.id != t2.id condition.

A "race condition" exists when multithreaded (or otherwise parallel) code that would access a shared resource could do so in such a way as to cause unexpected results.

Take this example:

for ( int i = 0; i < 10000000; i++ )
{
   x = x + 1; 
}

If you had 5 threads executing this code at once, the value of x WOULD NOT end up being 50,000,000. It would in fact vary with each run.

This is because, in order for each thread to increment the value of x, they have to do the following: (simplified, obviously)

Retrieve the value of x
Add 1 to this value
Store this value to x

Any thread can be at any step in this process at any time, and they can step on each other when a shared resource is involved. The state of x can be changed by another thread during the time between x is being read and when it is written back.

Let's say a thread retrieves the value of x, but hasn't stored it yet. Another thread can also retrieve the same value of x (because no thread has changed it yet) and then they would both be storing the same value (x+1) back in x!

Example:

Thread 1: reads x, value is 7
Thread 1: add 1 to x, value is now 8
Thread 2: reads x, value is 7
Thread 1: stores 8 in x
Thread 2: adds 1 to x, value is now 8
Thread 2: stores 8 in x

Race conditions can be avoided by employing some sort of locking mechanism before the code that accesses the shared resource:

for ( int i = 0; i < 10000000; i++ )
{
   //lock x
   x = x + 1; 
   //unlock x
}

Here, the answer comes out as 50,000,000 every time.

For more on locking, search for: mutex, semaphore, critical section, shared resource.

I am not 100% certain, but I think this does what you want using prop.table. See mostly the last 3 lines. The rest of the code is just creating fake data.

set.seed(1234)

total_bill <- rnorm(50, 25, 3)
tip <- 0.15 * total_bill + rnorm(50, 0, 1)
sex <- rbinom(50, 1, 0.5)
smoker <- rbinom(50, 1, 0.3)
day <- ceiling(runif(50, 0,7))
time <- ceiling(runif(50, 0,3))
size <- 1 + rpois(50, 2)
my.data <- as.data.frame(cbind(total_bill, tip, sex, smoker, day, time, size))
my.data

my.table <- table(my.data$smoker)

my.prop <- prop.table(my.table)

cbind(my.table, my.prop)

If you are using mysql client you can set up the resultFormat per session e.g.

mysql -h localhost -u root --resutl-format=json

or

mysql -h localhost -u root --vertical

Update your view with null value instead of parent viewgroup in Adapter viewholder onCreateViewHolder method.

@Override
public AdapterItemSku.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    View view = inflator.inflate(R.layout.layout_item, null, false);
    return new MyViewHolder(view);
}

Also, can be done using "stringr" library:

> library(stringr)
> chars <- "test"
> value <- "es"
> str_detect(chars, value)
[1] TRUE

### For multiple value case:
> value <- c("es", "l", "est", "a", "test")
> str_detect(chars, value)
[1]  TRUE FALSE  TRUE FALSE  TRUE

This works:

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

It will produce:

'abcdgxre'

You can also use a delimiter like a comma to produce:

'a,b,c,d,g,x,r,e'

By using:

','.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

Here is a solution using functions plot(), polygon() and lines().

 set.seed(1234)
 df <- data.frame(x =1:10,
                 F =runif(10,1,2),
                 L =runif(10,0,1),
                 U =runif(10,2,3))


 plot(df$x, df$F, ylim = c(0,4), type = "l")
 #make polygon where coordinates start with lower limit and 
 # then upper limit in reverse order
 polygon(c(df$x,rev(df$x)),c(df$L,rev(df$U)),col = "grey75", border = FALSE)
 lines(df$x, df$F, lwd = 2)
 #add red lines on borders of polygon
 lines(df$x, df$U, col="red",lty=2)
 lines(df$x, df$L, col="red",lty=2)

I went through this when trying to get a clientcert and private key out of a keystore.

The link above posted by welsh was great, but there was an extra step on my redhat distribution. If curl is built with NSS ( run curl --version to see if you see NSS listed) then you need to import the keys into an NSS keystore. I went through a bunch of convoluted steps, so this may not be the cleanest way, but it got things working

So export the keys into .p12

keytool -importkeystore -srckeystore $jksfile -destkeystore $p12file \
        -srcstoretype JKS -deststoretype PKCS12 \
        -srcstorepass $jkspassword -deststorepass $p12password  
        -srcalias $myalias -destalias $myalias \
        -srckeypass $keypass -destkeypass $keypass -noprompt

And generate the pem file that holds only the key

 echo making ${fileroot}.key.pem
 openssl pkcs12 -in $p12 -out ${fileroot}.key.pem  \
         -passin pass:$p12password  \
         -passout pass:$p12password  -nocerts

• Make an empty keystore:

mkdir ~/nss
chmod 700 ~/nss
certutil -N -d ~/nss

• Import the keys into the keystore

pks12util -i <mykeys>.p12 -d ~/nss -W <password for cert >

Now curl should work.

curl --insecure --cert <client cert alias>:<password for cert> \
     --key ${fileroot}.key.pem  <URL>

As I mentioned, there may be other ways to do this, but at least this was repeatable for me. If curl is compiled with NSS support, I was not able to get it to pull the client cert from a file.

Open command prompt and run the following commands

 C:\Users\username>netstat -o -n -a | findstr 0.0:3000
   TCP    0.0.0.0:3000      0.0.0.0:0              LISTENING       3116

C:\Users\username>taskkill /F /PID 3116

, here 3116 is the process ID

I created a more comprehensive and cleaner version that some people might find useful for remembering which name corresponds to which value. I used Chrome Dev Tool's color code and labels are organized symmetrically to pick up analogies faster:

• Note 1: clientLeft also includes the width of the vertical scroll bar if the direction of the text is set to right-to-left (since the bar is displayed to the left in that case)

• Note 2: the outermost line represents the closest positioned parent (an element whose position property is set to a value different than static or initial). Thus, if the direct container isn’t a positioned element, then the line doesn’t represent the first container in the hierarchy but another element higher in the hierarchy. If no positioned parent is found, the browser will take the html or body element as reference

Hope somebody finds it useful, just my 2 cents ;)

They are stored in the CGI fieldstorage object.

import cgi
form = cgi.FieldStorage()

print "The user entered %s" % form.getvalue("uservalue")

I'd suggest using such extension method:

public static class DataColumnCollectionExtensions
{
    public static IEnumerable<DataColumn> AsEnumerable(this DataColumnCollection source)
    {
        return source.Cast<DataColumn>();
    }
}

And therefore:

string[] columnNames = dataTable.Columns.AsEnumerable().Select(column => column.Name).ToArray();

You may also implement one more extension method for DataTable class to reduce code:

public static class DataTableExtensions
{
    public static IEnumerable<DataColumn> GetColumns(this DataTable source)
    {
        return source.Columns.AsEnumerable();
    }
}

And use it as follows:

string[] columnNames = dataTable.GetColumns().Select(column => column.Name).ToArray();

Either the parameter supplied for ZIP_CODE is larger (in length) than ZIP_CODEs column width or the parameter supplied for CITY is larger (in length) than CITYs column width.

It would be interesting to know the values supplied for the two ? placeholders.

This will work but there is still the possibility of a null record being returned. Though you may be setting the email address to a string of length zero when you insert the record, you may still want to handle the case of a NULL email address getting into the system somehow.

     $aUsers=$this->readToArray('
     SELECT `userID` 
     FROM `users` 
     WHERE `userID` 
     IN(SELECT `userID`
               FROM `users_indvSettings`
               WHERE `indvSettingID`=5 AND `optionID`='.$time.')
     AND `email` != "" AND `email` IS NOT NULL
     ');

img{display: flex; max-width: 80%; margin: auto;}

This is working for me. You can also use display: table in this case. Moreover, if you don't want to stick to this approach you can use the following:

img{position: relative; left: 50%;}

You could also try to enable long file paths.

If you run Windows 10 Home Edition you could change your Registry to enable long paths.

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem in regedit and then set LongPathsEnabled to 1.

If you have Windows 10 Pro or Enterprise you could also use Local Group Policies.

Go to Computer Configuration ? Administrative Templates ? System ? Filesystem in gpedit.msc, open Enable Win32 long paths and set it to Enabled.

In JPQL the same is actually true in the spec. The JPA spec does not allow an alias to be given to a fetch join. The issue is that you can easily shoot yourself in the foot with this by restricting the context of the join fetch. It is safer to join twice.

This is normally more an issue with ToMany than ToOnes. For example,

Select e from Employee e 
join fetch e.phones p 
where p.areaCode = '613'

This will incorrectly return all Employees that contain numbers in the '613' area code but will left out phone numbers of other areas in the returned list. This means that an employee that had a phone in the 613 and 416 area codes will loose the 416 phone number, so the object will be corrupted.

Granted, if you know what you are doing, the extra join is not desirable, some JPA providers may allow aliasing the join fetch, and may allow casting the Criteria Fetch to a Join.

Solution

The compiler is warning about this for a reason. It's very rare that this warning should simply be ignored, and it's easy to work around. Here's how:

if (!_controller) { return; }
SEL selector = NSSelectorFromString(@"someMethod");
IMP imp = [_controller methodForSelector:selector];
void (*func)(id, SEL) = (void *)imp;
func(_controller, selector);

Or more tersely (though hard to read & without the guard):

SEL selector = NSSelectorFromString(@"someMethod");
((void (*)(id, SEL))[_controller methodForSelector:selector])(_controller, selector);

Explanation

What's going on here is you're asking the controller for the C function pointer for the method corresponding to the controller. All NSObjects respond to methodForSelector:, but you can also use class_getMethodImplementation in the Objective-C runtime (useful if you only have a protocol reference, like id<SomeProto>). These function pointers are called IMPs, and are simple typedefed function pointers (id (*IMP)(id, SEL, ...))¹. This may be close to the actual method signature of the method, but will not always match exactly.

Once you have the IMP, you need to cast it to a function pointer that includes all of the details that ARC needs (including the two implicit hidden arguments self and _cmd of every Objective-C method call). This is handled in the third line (the (void *) on the right hand side simply tells the compiler that you know what you're doing and not to generate a warning since the pointer types don't match).

Finally, you call the function pointer².

Complex Example

When the selector takes arguments or returns a value, you'll have to change things a bit:

SEL selector = NSSelectorFromString(@"processRegion:ofView:");
IMP imp = [_controller methodForSelector:selector];
CGRect (*func)(id, SEL, CGRect, UIView *) = (void *)imp;
CGRect result = _controller ?
  func(_controller, selector, someRect, someView) : CGRectZero;

Reasoning for Warning

The reason for this warning is that with ARC, the runtime needs to know what to do with the result of the method you're calling. The result could be anything: void, int, char, NSString *, id, etc. ARC normally gets this information from the header of the object type you're working with.³

There are really only 4 things that ARC would consider for the return value:⁴

1. Ignore non-object types (void, int, etc)
2. Retain object value, then release when it is no longer used (standard assumption)
3. Release new object values when no longer used (methods in the init/ copy family or attributed with ns_returns_retained)
4. Do nothing & assume returned object value will be valid in local scope (until inner most release pool is drained, attributed with ns_returns_autoreleased)

The call to methodForSelector: assumes that the return value of the method it's calling is an object, but does not retain/release it. So you could end up creating a leak if your object is supposed to be released as in #3 above (that is, the method you're calling returns a new object).

For selectors you're trying to call that return void or other non-objects, you could enable compiler features to ignore the warning, but it may be dangerous. I've seen Clang go through a few iterations of how it handles return values that aren't assigned to local variables. There's no reason that with ARC enabled that it can't retain and release the object value that's returned from methodForSelector: even though you don't want to use it. From the compiler's perspective, it is an object after all. That means that if the method you're calling, someMethod, is returning a non object (including void), you could end up with a garbage pointer value being retained/released and crash.

Additional Arguments

One consideration is that this is the same warning will occur with performSelector:withObject: and you could run into similar problems with not declaring how that method consumes parameters. ARC allows for declaring consumed parameters, and if the method consumes the parameter, you'll probably eventually send a message to a zombie and crash. There are ways to work around this with bridged casting, but really it'd be better to simply use the IMP and function pointer methodology above. Since consumed parameters are rarely an issue, this isn't likely to come up.

Static Selectors

Interestingly, the compiler will not complain about selectors declared statically:

[_controller performSelector:@selector(someMethod)];

The reason for this is because the compiler actually is able to record all of the information about the selector and the object during compilation. It doesn't need to make any assumptions about anything. (I checked this a year a so ago by looking at the source, but don't have a reference right now.)

Suppression

In trying to think of a situation where suppression of this warning would be necessary and good code design, I'm coming up blank. Someone please share if they have had an experience where silencing this warning was necessary (and the above doesn't handle things properly).

More

It's possible to build up an NSMethodInvocation to handle this as well, but doing so requires a lot more typing and is also slower, so there's little reason to do it.

History

When the performSelector: family of methods was first added to Objective-C, ARC did not exist. While creating ARC, Apple decided that a warning should be generated for these methods as a way of guiding developers toward using other means to explicitly define how memory should be handled when sending arbitrary messages via a named selector. In Objective-C, developers are able to do this by using C style casts on raw function pointers.

With the introduction of Swift, Apple has documented the performSelector: family of methods as "inherently unsafe" and they are not available to Swift.

Over time, we have seen this progression:

1. Early versions of Objective-C allow performSelector: (manual memory management)
2. Objective-C with ARC warns for use of performSelector:
3. Swift does not have access to performSelector: and documents these methods as "inherently unsafe"

The idea of sending messages based on a named selector is not, however, an "inherently unsafe" feature. This idea has been used successfully for a long time in Objective-C as well as many other programming languages.

¹ All Objective-C methods have two hidden arguments, self and _cmd that are implicitly added when you call a method.

² Calling a NULL function is not safe in C. The guard used to check for the presence of the controller ensures that we have an object. We therefore know we'll get an IMP from methodForSelector: (though it may be _objc_msgForward, entry into the message forwarding system). Basically, with the guard in place, we know we have a function to call.

³ Actually, it's possible for it to get the wrong info if declare you objects as id and you're not importing all headers. You could end up with crashes in code that the compiler thinks is fine. This is very rare, but could happen. Usually you'll just get a warning that it doesn't know which of two method signatures to choose from.

⁴ See the ARC reference on retained return values and unretained return values for more details.

It seems nobody found a solution for this. I don't have one based on only css neither but by using this JavaScript trick I usually can handle disabled input fields.

Remember that disabled fields always follow the style that they got before becoming disabled. So the trick would be 1- Enabling them 2-Change the class 3- Disable them again. Since this happens very fast user cannot understand what happened.

A simple JavaScript code would be something like:

function changeDisabledClass (id, disabledClass){
var myInput=document.getElementById(id);
myInput.disabled=false;             //First make sure it is not disabled
myInput.className=disabledClass;    //change the class
myInput.disabled=true;             //Re-disable it
}

For HTTP things, the current choice should be: Requests- HTTP for Humans

The getActiveNetworkInfo() method of ConnectivityManager returns a NetworkInfo instance representing the first connected network interface it can find or null if none of the interfaces are connected. Checking if this method returns null should be enough to tell if an internet connection is available or not.

private boolean isNetworkAvailable() {
    ConnectivityManager connectivityManager 
          = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
    return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}

You will also need:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

in your android manifest.

Edit:

Note that having an active network interface doesn't guarantee that a particular networked service is available. Network issues, server downtime, low signal, captive portals, content filters and the like can all prevent your app from reaching a server. For instance you can't tell for sure if your app can reach Twitter until you receive a valid response from the Twitter service.

This is not strictly a bash solution but you can use piping with sed to get the last row of previous commands output.

First lets see what i have in folder "a"

rasjani@helruo-dhcp022206::~$ find a
a
a/foo
a/bar
a/bat
a/baz
rasjani@helruo-dhcp022206::~$ 

Then, your example with ls and cd would turn to sed & piping into something like this:

rasjani@helruo-dhcp022206::~$ cd `find a |sed '$!d'`
rasjani@helruo-dhcp022206::~/a/baz$ pwd
/home/rasjani/a/baz
rasjani@helruo-dhcp022206::~/a/baz$

So, the actual magic happens with sed, you pipe what ever output of what ever command into sed and sed prints the last row which you can use as parameter with back ticks. Or you can combine that to xargs also. ("man xargs" in shell is your friend)

In JavaScript, most functions are both callable and instantiable: they have both a [[Call]] and [[Construct]] internal methods.

As callable objects, you can use parentheses to call them, optionally passing some arguments. As a result of the call, the function can return a value.

var player = makeGamePlayer("John Smith", 15, 3);

The code above calls function makeGamePlayer and stores the returned value in the variable player. In this case, you may want to define the function like this:

function makeGamePlayer(name, totalScore, gamesPlayed) {
  // Define desired object
  var obj = {
    name:  name,
    totalScore: totalScore,
    gamesPlayed: gamesPlayed
  };
  // Return it
  return obj;
}

Additionally, when you call a function you are also passing an additional argument under the hood, which determines the value of this inside the function. In the case above, since makeGamePlayer is not called as a method, the this value will be the global object in sloppy mode, or undefined in strict mode.

As constructors, you can use the new operator to instantiate them. This operator uses the [[Construct]] internal method (only available in constructors), which does something like this:

1. Creates a new object which inherits from the .prototype of the constructor
2. Calls the constructor passing this object as the this value
3. It returns the value returned by the constructor if it's an object, or the object created at step 1 otherwise.

var player = new GamePlayer("John Smith", 15, 3);

The code above creates an instance of GamePlayer and stores the returned value in the variable player. In this case, you may want to define the function like this:

function GamePlayer(name,totalScore,gamesPlayed) {
  // `this` is the instance which is currently being created
  this.name =  name;
  this.totalScore = totalScore;
  this.gamesPlayed = gamesPlayed;
  // No need to return, but you can use `return this;` if you want
}

By convention, constructor names begin with an uppercase letter.

The advantage of using constructors is that the instances inherit from GamePlayer.prototype. Then, you can define properties there and make them available in all instances

You can also set the dimensions to the canvas

<canvas id="myChart" width="400" height="400"></canvas>

And then set the responsive options to false to always maintain the chart at the size specified.

options: {
    responsive: false,
}

you can use this too

.parent:hover * {
   /* ... */
}

#many .more.selectors h4 + p { ... }

This is called the adjacent sibling selector.

I got same error and it was due to older Lombok version. Check and update your Lombok version, Changes in Lombok

v1.18.4 - Many improvements for lombok's JDK10/11 support.

If you not want include other function like 'ReDimPreserve' could use temporal matrix for resizing. On based to your code:

 Dim n As Integer, m As Integer, i as Long, j as Long
 Dim arrTemporal() as Variant

    n = 1
    m = 0
    Dim arrCity() As String
    ReDim arrCity(n, m)

    n = n + 1
    m = m + 1

    'VBA automatically adapts the size of the receiving matrix.
    arrTemporal = arrCity
    ReDim arrCity(n, m)

    'Loop for assign values to arrCity
    For i = 1 To UBound(arrTemporal , 1)
        For j = 1 To UBound(arrTemporal , 2)
            arrCity(i, j) = arrTemporal (i, j)
        Next
    Next

If you not declare of type VBA assume that is Variant.

Dim n as Integer, m As Integer

This is usually happens when the remote is down/unavailable; or the remote machine doesn't have ssh installed; or a firewall doesn't allow a connection to be established to the remote host.

ssh returns 255 when an error occurred or 255 is returned by the remote script:

 EXIT STATUS

     ssh exits with the exit status of the remote command or
     with 255 if an error occurred.

Usually you would an error message something similar to:

ssh: connect to host host.domain.com port 22: No route to host

Or

ssh: connect to host HOSTNAME port 22: Connection refused

Check-list:

• What happens if you run the ssh command directly from the command line?

• Are you able to ping that machine?

• Does the remote has ssh installed?

• If installed, then is the ssh service running?

I solved this by changing owner from root to me on all files on /db dir.

Just do ls -l on that folder, if any of the filer is owned by root just change it to you, using: sudo chown user file

One consideration is that FTP can use non-standard ports, which can make getting though firewalls difficult (especially if you're using SSL). HTTP is typically on a known port, so this is rarely a problem.

If you do decide to use FTP, make sure you read about Active and Passive FTP.

In terms of performance, at the end of the day they're both spewing files directly down TCP connections so should be about the same.

I've added the following script as manage.sh inside my Django project, it sources the virtualenv and then runs the manage.py script with whatever arguments you pass to it. It makes it very easy in general to run commands inside the virtualenv (cron, systemd units, basically anywhere):

#! /bin/bash

# this is a convenience script that first sources the venv (assumed to be in
# ../venv) and then executes manage.py with whatever arguments you supply the
# script with. this is useful if you need to execute the manage.py from
# somewhere where the venv isn't sourced (e.g. system scripts)

# get the script's location
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null 2>&1 && pwd )"

# source venv <- UPDATE THE PATH HERE WITH YOUR VENV's PATH
source $DIR/../venv/bin/activate

# run manage.py script
$DIR/manage.py "$@"

Then in your cron entry you can just run:

0 3 * * * /home/user/project/manage.sh command arg

Just remember that you need to make the manage.sh script executable

Basically every 5 seconds the js will post to a php file that will track the user and the users ip address. Active users are simply a database record that have an update to the database time stamp within 5 seconds. Old users stop updating to the database. The ip address is used just to ensure that a user is unique so 2 people on the site at the same time don't register as 1 user.

Probably not the most efficient solution but it does the job.

You can use the col element as specified in HTML 4.0 (link). It works in every browser. You can give it an ID or a class or an inline style. only caveat is that it affects the whole column across all rows. Example:

<table>
    <col />
    <col width="50" />
    <col id="anId" />
    <col class="whatever" />
    <col style="border:1px solid #000;" />
    <tbody>
        <tr>
            <td>One</td>
            <td>Two</td>
            <td>Three</td>
            <td>Four</td>
            <td>Five</td>
        </tr>
    </tbody>
</table>

Don't forget any? which is generally !empty?. In Rails I typically check for the presence of something at the end of a statement with if something or unless something then use blank? where needed since it seems to work everywhere.

Just fetch. only gets one row. So no foreach loop needed :D

$row  = $STH -> fetch();

example (ty northkildonan):

$dbh = new PDO(" --- connection string --- "); 
$stmt = $dbh->prepare("SELECT name FROM mytable WHERE id=4 LIMIT 1"); 
$stmt->execute(); 
$row = $stmt->fetch();

This look like a duplicate of JSTL conditional check.

The error is having the && outside the expression. Instead use

<c:if test="${ISAJAX == 0 && ISDATE == 0}">

  class MyActivity{
    private final Handler handler = new Handler();
    private Runnable yourRunnable;
    protected void onCreate(@Nullable Bundle savedInstanceState) {
       // ....
       this.yourRunnable = new Runnable() {
               @Override
               public void run() {
                   //code
               }
            };

        this.handler.postDelayed(this.yourRunnable, 2000);
       }


     @Override
  protected void onDestroy() {
      // to avoid memory leaks
      this.handler.removeCallbacks(this.yourRunnable);
      }
    }

And to be double sure you can be combined it with the "static class" method as described in the tronman answer

You need to configure the security group as stated by cyraxjoe. Along with that you also need to open System port. Steps to open port in windows :-

1. On the Start menu, click Run, type WF.msc, and then click OK.
2. In the Windows Firewall with Advanced Security, in the left pane, right-click Inbound Rules, and then click New Rule in the action pane.
3. In the Rule Type dialog box, select Port, and then click Next.
4. In the Protocol and Ports dialog box, select TCP. Select Specific local ports, and then type the port number , such as 8787 for the default instance. Click Next.
5. In the Action dialog box, select Allow the connection, and then click Next.
6. In the Profile dialog box, select any profiles that describe the computer connection environment when you want to connect , and then click Next.
7. In the Name dialog box, type a name and description for this rule, and then click Finish.

If you are in need of the shadows properly to be applied then you have to do the following.

Consider this view, defined with a background drawable:

<TextView
    android:id="@+id/myview"
    ...
    android:elevation="2dp"
    android:background="@drawable/myrect" />

The background drawable is defined as a rectangle with rounded corners:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
    <solid android:color="#42000000" />
    <corners android:radius="5dp" />
</shape>

This is the recomended way of appying shadows check this out https://developer.android.com/training/material/shadows-clipping.html#Shadows

I would just like to throw the idea of annotation : @getter and @setter. With @getter, you should be able to obj = class.field but not class.field = obj. With @setter, vice versa. With @getter and @setter you should be able to do both. This would preserve encapsulation and reduce the time by not calling trivial methods at runtime.

your code :

 AddTaskViewController *add = [[AddTaskViewController alloc] init];
 [self presentViewController:add animated:YES completion:nil];

this code can goes to the other controller , but you get a new viewController , not the controller of your storyboard, you can do like this :

AddTaskViewController *add = [self.storyboard instantiateViewControllerWithIdentifier:@"YourStoryboardID"];
[self presentViewController:add animated:YES completion:nil];

Just in case someone else comes across this, to clarify the answer `n is grave accent n, not single tick n

Follow the code below exactly matched with your case.

1. Create an interface of the web element for the div under div with class as facetContainerDiv

ie for

<div class="facetContainerDiv">
    <div>

    </div>
</div>

2. Create an IList with all the elements inside the second div i.e for,

<label class="facetLabel">
   <input class="facetCheck" type="checkbox" />
</label>
<label class="facetLabel">
   <input class="facetCheck" type="checkbox" />
</label>
<label class="facetLabel">
   <input class="facetCheck" type="checkbox" />
</label>
<label class="facetLabel">
   <input class="facetCheck" type="checkbox" />
</label>
<label class="facetLabel">
   <input class="facetCheck" type="checkbox" />
</label>

3. Access each check boxes using the index

Please find the code below

  class ChechBoxClickWthIndex
    {
        static void Main(string[] args)
        {

            IWebDriver driver = new FirefoxDriver();

            driver.Navigate().GoToUrl("file:///C:/Users/chery/Desktop/CheckBox.html");

            // Create an interface WebElement of the div under div with **class as facetContainerDiv**
            IWebElement WebElement =    driver.FindElement(By.XPath("//div[@class='facetContainerDiv']/div"));
            // Create an IList and intialize it with all the elements of div under div with **class as facetContainerDiv**
            IList<IWebElement> AllCheckBoxes = WebElement.FindElements(By.XPath("//label/input"));
            int RowCount = AllCheckBoxes.Count;
            for (int i = 0; i < RowCount; i++)
            {
            // Check the check boxes based on index
               AllCheckBoxes[i].Click();

            }
            Console.WriteLine(RowCount);
            Console.ReadLine(); 

        }
    }
}

Here is solution that addresses the issue mentioned with previous answers, when isModal() returns true if pushed UIViewController is in a presented UINavigationController stack.

extension UIViewController {
    var isModal: Bool {
        if let index = navigationController?.viewControllers.firstIndex(of: self), index > 0 {
            return false
        } else if presentingViewController != nil {
            return true
        } else if navigationController?.presentingViewController?.presentedViewController == navigationController {
            return true
        } else if tabBarController?.presentingViewController is UITabBarController {
            return true
        } else {
            return false
        }
    }
}

It does work for me so far. If some optimizations, please share.

If you want to get the actually dependency path of specific package and want to know why you have it, you can simply ask yarn why <MODULE>. example:

    $> yarn why mime-db
    yarn why v1.5.1
    [1/4] Why do we have the module "mime-db"...?
    [2/4] Initialising dependency graph...
    [3/4] Finding dependency...
    [4/4] Calculating file sizes...
    => Found "[email protected]"
    info Reasons this module exists
       - "coveralls#request#mime-types" depends on it
       - Hoisted from "coveralls#request#mime-types#mime-db"
    info Disk size without dependencies: "196kB"
    info Disk size with unique dependencies: "196kB"
    info Disk size with transitive dependencies: "196kB"

If you want to remove the [ or the ], use the expression: "\\[|\\]".

The two backslashes escape the square bracket and the pipe is an "or".

I had many issues involving C# and SqlServer. I ended up doing the following:

1. On SQL Server I use the DateTime column type
2. On c# I use the .ToString("yyyy-MM-dd HH:mm:ss") method

Also make sure that all your machines run on the same timezone.

Regarding the different result sets you get, your first example is "July First" while the second is "4th of July" ...

Also, the second example can be also interpreted as "April 7th", it depends on your server localization configuration (my solution doesn't suffer from this issue).

EDIT: hh was replaced with HH, as it doesn't seem to capture the correct hour on systems with AM/PM as opposed to systems with 24h clock. See the comments below.

I use the following class. I found it on the Internet once, postulated to be the best NOW().

/// <summary>Class to get current timestamp with enough precision</summary>
static class CurrentMillis
{
    private static readonly DateTime Jan1St1970 = new DateTime (1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
    /// <summary>Get extra long current timestamp</summary>
    public static long Millis { get { return (long)((DateTime.UtcNow - Jan1St1970).TotalMilliseconds); } }
}

You can check your respone content, just console.log it and you will see whitch property have a status code. If you do not understand jsons, please refer to the video: https://www.youtube.com/watch?v=Bv_5Zv5c-Ts

It explains very basic knowledge that let you feel more comfortable with javascript.

You can do it with shorter version of ajax request, please see code above:

$.get("example.url.com", function(data) {
                console.log(data);
            }).done(function() {
               // TO DO ON DONE
            }).fail(function(data, textStatus, xhr) {
                 //This shows status code eg. 403
                 console.log("error", data.status);
                 //This shows status message eg. Forbidden
                 console.log("STATUS: "+xhr);
            }).always(function() {
                 //TO-DO after fail/done request.
                 console.log("ended");
            });

Example console output:

error 403 
STATUS: Forbidden 
ended

I am not sure, but maybe this logic would work.

var d = 10;
var prevDate = "";
var x = 0;
var oldVal = "";
var func = function (d) {
    if (x == 0 && d != prevDate && prevDate == "") {
        oldVal = d;
        prevDate = d;
    }
    else if (x == 1 && prevDate != d) {
        oldVal = prevDate;
        prevDate = d;
    }
    console.log(oldVal);
    x = 1;
};
/*
         ============================================
         Try:
         func(2);
         func(3);
         func(4);
*/

Just create An AnyName.cs file and paste following code.

using System;
using System.IO;
using Microsoft.Extensions.Configuration;

namespace Custom
{
    static class ConfigurationManager
    {
        public static IConfiguration AppSetting { get; }
        static ConfigurationManager()
        {
            AppSetting = new ConfigurationBuilder()
                    .SetBasePath(Directory.GetCurrentDirectory())
                    .AddJsonFile("YouAppSettingFile.json")
                    .Build();
        }
    }
}

Must replace YouAppSettingFile.json file name with your file name.
Your .json file should look like below.

{
    "GrandParent_Key" : {
        "Parent_Key" : {
            "Child_Key" : "value1"
        }
    },
    "Parent_Key" : {
        "Child_Key" : "value2"
    },
    "Child_Key" : "value3"
}

Now you can use it.
Don't forget to Add Reference in your class where you want to use.

using Custom;

Code to retrieve value.

string value1 = ConfigurationManager.AppSetting["GrandParent_Key:Parent_Key:Child_Key"];
string value2 = ConfigurationManager.AppSetting["Parent_Key:Child_Key"];
string value3 = ConfigurationManager.AppSetting["Child_Key"];

You can use '?' to set custom parameters in string using PreparedStatments.

statement =con.prepareStatement("SELECT * from employee WHERE  userID = ?");
statement.setString(1, userID);
ResultSet rs = statement.executeQuery();

If you directly pass userID in query as you are doing then it may get attacked by SQL INJECTION Attack.

You could use a Common Table Expression to get the top 10 distinct ID's and then join those to the rest of your data:

;WITH TopTenIDs AS
( 
   SELECT DISTINCT TOP 10 id
   FROM dm.labs 
   ORDER BY ......
)
SELECT 
    tti.id, pl.nm, pl.val, pl.txt_val
FROM
    TopTenIDs tti
INNER JOIN
    dm.labs pl ON pl.id = tti.id
INNER JOIN 
    mas_data.patients p ON pl.id = p.id
WHERE
    pl.nm like '%LDL%'
    AND val IS NOT NULL

That should work. Mind you: if you have a "TOP x" clause, you typically also need an ORDER BY clause - if you want the TOP 10, you need to tell the system in what order that "TOP" is.

PS: why do you even join the "patients" table, if you never select any fields from it??

This is how I did it. You don't need to delete Java 9 or newer version.

Step 1: Install Java 8

You can download Java 8 from here: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Step 2: After installation of Java 8. Confirm installation of all versions.Type the following command in your terminal.

/usr/libexec/java_home -V

Step 3: Edit .bash_profile

sudo nano ~/.bash_profile

Step 4: Add 1.8 as default. (Add below line to bash_profile file).

export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)

Now Press CTRL+X to exit the bash. Press 'Y' to save changes.

Step 5: Reload bash_profile

source ~/.bash_profile

Step 6: Confirm current version of Java

java -version

Haven't seen anything like this. It's concise, easy to understand & doesn't rely on any overly complicated regular expressions.

function moneyFormat(price, sign = '$') {
  const pieces = parseFloat(price).toFixed(2).split('')
  let ii = pieces.length - 3
  while ((ii-=3) > 0) {
    pieces.splice(ii, 0, ',')
  }
  return sign + pieces.join('')
}

console.log(
  moneyFormat(100),
  moneyFormat(1000),
  moneyFormat(10000.00),
  moneyFormat(1000000000000000000)
)

Here is a version with more options in the final output to allow formatting different currencies in different locality formats.

// higher order function that takes options then a price and will return the formatted price
const makeMoneyFormatter = ({
  sign = '$',
  delimiter = ',',
  decimal = '.',
  append = false,
  precision = 2,
  round = true,
  custom
} = {}) => value => {
  
  const e = [1, 10, 100, 1000, 10000, 100000, 1000000, 10000000]
  
  value = round
    ? (Math.round(value * e[precision]) / e[precision])
    : parseFloat(value)
  
  const pieces = value
    .toFixed(precision)
    .replace('.', decimal)
    .split('')
  
  let ii = pieces.length - (precision ? precision + 1 : 0)
  
  while ((ii-=3) > 0) {
    pieces.splice(ii, 0, delimiter)
  }
  
  if (typeof custom === 'function') {
    return custom({
      sign,
      float: value, 
      value: pieces.join('') 
    })
  }
  
  return append
    ? pieces.join('') + sign
    : sign + pieces.join('')
}

// create currency converters with the correct formatting options
const formatDollar = makeMoneyFormatter()
const formatPound = makeMoneyFormatter({ 
  sign: '£',
  precision: 0
})
const formatEuro = makeMoneyFormatter({
  sign: '€',
  delimiter: '.',
  decimal: ',',
  append: true
})

const customFormat = makeMoneyFormatter({
  round: false,
  custom: ({ value, float, sign }) => `SALE:$${value}USD`
})

console.log(
  formatPound(1000),
  formatDollar(10000.0066),
  formatEuro(100000.001),
  customFormat(999999.555)
)

You could use FindBin, Cwd, File::Basename, or a combination of them. They're all in the base distribution of Perl IIRC.

I used Cwd in the past:

Cwd:

use Cwd qw(abs_path);
my $path = abs_path($0);
print "$path\n";

Hit this error trying to run terraform/terragrunt (Single go binary).

Using which terragrunt to find where executable was, got strange error when running it in local dir or with full path

bash: ./terragrunt: No such file or directory

Problem was that there was two installations of terragrunt, used brew uninstall terragrunt to remove one fixed it.

After removing the one, which terragrunt showed the new path /usr/bin/terragrunt everything worked fine.

cat /path/* | bash

OR

cat commands.txt | bash

Another key difference between hashtable and hashmap is that Iterator in the HashMap is fail-fast while the enumerator for the Hashtable is not and throw ConcurrentModificationException if any other Thread modifies the map structurally by adding or removing any element except Iterator's own remove() method. But this is not a guaranteed behavior and will be done by JVM on best effort."

Pattern.compile() allow to reuse a regex multiple times (it is threadsafe). The performance benefit can be quite significant.

I did a quick benchmark:

    @Test
    public void recompile() {
        var before = Instant.now();
        for (int i = 0; i < 1_000_000; i++) {
            Pattern.compile("ab").matcher("abcde").matches();
        }
        System.out.println("recompile " + Duration.between(before, Instant.now()));
    }

    @Test
    public void compileOnce() {
        var pattern = Pattern.compile("ab");
        var before = Instant.now();
        for (int i = 0; i < 1_000_000; i++) {
            pattern.matcher("abcde").matches();
        }
        System.out.println("compile once " + Duration.between(before, Instant.now()));
    }

compileOnce was between 3x and 4x faster. I guess it highly depends on the regex itself but for a regex that is often used, I go for a static Pattern pattern = Pattern.compile(...)

A interesting writeup on the logical differences: SQL Server: JOIN vs IN vs EXISTS - the logical difference

I am pretty sure that assuming that the relations and indexes are maintained a Join will perform better overall (more effort goes into working with that operation then others). If you think about it conceptually then its the difference between 2 queries and 1 query.

You need to hook it up to the Query Analyzer and try it and see the difference. Also look at the Query Execution Plan and try to minimize steps.

This might help, I used to fi my files like this: http://security102.blogspot.ru/2010/04/findreplace-of-nul-objects-in-notepad.html

Basically you need to replace \x00 characters with regular expressions

Facebook uses what's called the Open Graph Protocol to decide what things to display when you share a link. The OGP looks at your page and tries to decide what content to show. We can lend a hand and actually tell Facebook what to take from our page.

The way we do that is with og:meta tags.

The tags look something like this -

  <meta property="og:title" content="Stuffed Cookies" />
  <meta property="og:image" content="http://fbwerks.com:8000/zhen/cookie.jpg" />
  <meta property="og:description" content="The Turducken of Cookies" />
  <meta property="og:url" content="http://fbwerks.com:8000/zhen/cookie.html">

You'll need to place these or similar meta tags in the <head> of your HTML file. Don't forget to substitute the values for your own!

For more information you can read all about how Facebook uses these meta tags in their documentation. Here is one of the tutorials from there - https://developers.facebook.com/docs/opengraph/tutorial/

Facebook gives us a great little tool to help us when dealing with these meta tags - you can use the Debugger to see how Facebook sees your URL, and it'll even tell you if there are problems with it.

One thing to note here is that every time you make a change to the meta tags, you'll need to feed the URL through the Debugger again so that Facebook will clear all the data that is cached on their servers about your URL.

netstat will work (at the top something like this) tcp 0 0 10.x.xx.xx:ssh someipaddress.or.domainame:9379 ESTABLISHED

You don't need to do anything, the Model Binding will pass null to property without any problem.

You can check instance of Chart by using Chart.instances. This will give you all the charts instances. Now you can iterate on that instances and and change the data, which is present inside config. suppose you have only one chart in your page.

for (var _chartjsindex in Chart.instances) {
/* 
 * Here in the config your actual data and options which you have given at the 
   time of creating chart so no need for changing option only you can change data
*/
 Chart.instances[_chartjsindex].config.data = [];
 // here you can give add your data
 Chart.instances[_chartjsindex].update();
 // update will rewrite your whole chart with new value
 }

Try this

package main

import "fmt"
import "strconv"

func FloatToString(input_num float64) string {
    // to convert a float number to a string
    return strconv.FormatFloat(input_num, 'f', 6, 64)
}

func main() {
    fmt.Println(FloatToString(21312421.213123))
}

If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg

strconv.FormatFloat(input_num, 'f', -1, 64)

Personally I find fmt easier to use. (Playground link)

fmt.Printf("x = %.6f\n", 21312421.213123)

Or if you just want to convert the string

fmt.Sprintf("%.6f", 21312421.213123)

I believe you can use something such as

if ___ (

do this

) else if ___ (

do this

)

You can do like this also:

HTML:

<a><img src='https://encrypted-tbn2.google.com/images?q=tbn:ANd9GcQB3a3aouZcIPEF0di4r9uK4c0r9FlFnCasg_P8ISk8tZytippZRQ' onmouseover="somefunction();"></a>

In javascript:

function somefunction()
{
  //Do somethisg.
}

?

Try like this

#testdiv{
  border-left:1px solid;

}

For UNIX, at least, this works...

import commands
username = commands.getoutput("echo $(whoami)")
print username

edit: I just looked it up and this works on Windows and UNIX:

import commands
username = commands.getoutput("whoami")

On UNIX it returns your username, but on Windows, it returns your user's group, slash, your username.

--

I.E.

UNIX returns: "username"

Windows returns: "domain/username"

--

It's interesting, but probably not ideal unless you are doing something in the terminal anyway... in which case you would probably be using os.system to begin with. For example, a while ago I needed to add my user to a group, so I did (this is in Linux, mind you)

import os
os.system("sudo usermod -aG \"group_name\" $(whoami)")
print "You have been added to \"group_name\"! Please log out for this to take effect"

I feel like that is easier to read and you don't have to import pwd or getpass.

I also feel like having "domain/user" could be helpful in certain applications in Windows.

Ran into the same problem, I'm using maven so I added this to the pom in my web project:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version> <!-- just used the latest version, make sure you use the one you need -->
    <scope>provided</scope>
</dependency>

This fixed the problem and I used "provided" scope because like the OP, everything was already working in JBoss.

Here's where I found the solution: http://alfredjava.wordpress.com/2008/12/22/jstl-connot-resolved/

The following is a very simple C++ example that shows that if you want to use a function to set a pointer to point to an object, you need a pointer to a pointer. Otherwise, the pointer will keep reverting to null.

(A C++ answer, but I believe it's the same in C.)

(Also, for reference: Google("pass by value c++") = "By default, arguments in C++ are passed by value. When an argument is passed by value, the argument's value is copied into the function's parameter.")

So we want to set the pointer b equal to the string a.

#include <iostream>
#include <string>

void Function_1(std::string* a, std::string* b) {
  b = a;
  std::cout << (b == nullptr);  // False
}

void Function_2(std::string* a, std::string** b) {
  *b = a;
  std::cout << (b == nullptr);  // False
}

int main() {
  std::string a("Hello!");
  std::string* b(nullptr);
  std::cout << (b == nullptr);  // True

  Function_1(&a, b);
  std::cout << (b == nullptr);  // True

  Function_2(&a, &b);
  std::cout << (b == nullptr);  // False
}

// Output: 10100

What happens at the line Function_1(&a, b);?

• The "value" of &main::a (an address) is copied into the parameter std::string* Function_1::a. Therefore Function_1::a is a pointer to (i.e. the memory address of) the string main::a.

• The "value" of main::b (an address in memory) is copied into the parameter std::string* Function_1::b. Therefore there are now 2 of these addresses in memory, both null pointers. At the line b = a;, the local variable Function_1::b is then changed to equal Function_1::a (= &main::a), but the variable main::b is unchanged. After the call to Function_1, main::b is still a null pointer.

What happens at the line Function_2(&a, &b);?

• The treatment of the a variable is the same: within the function, Function_2::a is the address of the string main::a.

• But the variable b is now being passed as a pointer to a pointer. The "value" of &main::b (the address of the pointer main::b) is copied into std::string** Function_2::b. Therefore within Function_2, dereferencing this as *Function_2::b will access and modify main::b . So the line *b = a; is actually setting main::b (an address) equal to Function_2::a (= address of main::a) which is what we want.

If you want to use a function to modify a thing, be it an object or an address (pointer), you have to pass in a pointer to that thing. The thing that you actually pass in cannot be modified (in the calling scope) because a local copy is made.

(An exception is if the parameter is a reference, such as std::string& a. But usually these are const. Generally, if you call f(x), if x is an object you should be able to assume that f won't modify x. But if x is a pointer, then you should assume that f might modify the object pointed to by x.)

Include <tchar.h> which has the line:

#define _tWinMain wWinMain

This is not so much an answer to your original question as to one of the queries you had in the body of your question.

A little preamble, so that my naming doesn't seem strange:

import matplotlib
from matplotlib import rc
from matplotlib.figure import Figure
ax = self.figure.add_subplot( 111 )

As has been mentioned you can use ticklabel_format to specify that matplotlib should use scientific notation for large or small values:

ax.ticklabel_format(style='sci',scilimits=(-3,4),axis='both')

You can affect the way that this is displayed using the flags in rcParams (from matplotlib import rcParams) or by setting them directly. I haven't found a more elegant way of changing between '1e' and 'x10^' scientific notation than:

ax.xaxis.major.formatter._useMathText = True

This should give you the more Matlab-esc, and indeed arguably better appearance. I think the following should do the same:

rc('text', usetex=True)

That's the compiler that comes with Apple's XCode tools package. They've hacked on it a little, but basically it's just g++.

You can download XCode for free (well, mostly, you do have to sign up to become an ADC member, but that's free too) here: http://developer.apple.com/technology/xcode.html

Edit 2013-01-25: This answer was correct in 2010. It needs an update.

While XCode tools still has a command-line C++ compiler, In recent versions of OS X (I think 10.7 and later) have switched to clang/llvm (mostly because Apple wants all the benefits of Open Source without having to contribute back and clang is BSD licensed). Secondly, I think all you have to do to install XCode is to download it from the App store. I'm pretty sure it's free there.

So, in order to get g++ you'll have to use something like homebrew (seemingly the current way to install Open Source software on the Mac (though homebrew has a lot of caveats surrounding installing gcc using it)), fink (basically Debian's apt system for OS X/Darwin), or MacPorts (Basically, OpenBSDs ports system for OS X/Darwin) to get it.

Fink definitely has the right packages. On 2016-12-26, it had gcc 5 and gcc 6 packages.

I'm less familiar with how MacPorts works, though some initial cursory investigation indicates they have the relevant packages as well.

Yes it is possible to have multiple $(document).ready() calls. However, I don't think you can know in which way they will be executed. (source)

The official docker answer to Run multiple services in a container.

It explains how you can do it with an init system (systemd, sysvinit, upstart) , a script (CMD ./my_wrapper_script.sh) or a supervisor like supervisord.

The && workaround can work only for services that starts in background (daemons) or that will execute quickly without interaction and release the prompt. Doing this with an interactive service (that keeps the prompt) and only the first service will start.

<link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />

add this to your HTML Head. Of course the file "favicon.ico" has to exist. I think 16x16 or 32x32 pixel files are best.

You could try qemu, which is what the Android emulator uses. I believe it actually emulates the ARM hardware.

The only solution works on Ubuntu 12.04:

echo -e "new_password\nnew_password" | (passwd user)

But the second option only works when I change from:

echo "password:name" | chpasswd

To:

echo "user:password" | chpasswd

See explanations in original post: Changing password via a script

Here's how I got rid of mine:

.main .row .thumbnail {
    display: inline-block;
    border: 0px;
    background-color: transparent;
}

pathinfo is what you're looking for

PHP.net

$file_parts = pathinfo($filename);

switch($file_parts['extension'])
{
    case "jpg":
    break;

    case "exe":
    break;

    case "": // Handle file extension for files ending in '.'
    case NULL: // Handle no file extension
    break;
}

As of version 2.4, you can create a text index on the field(s) to search and use the $text operator for querying.

First, create the index:

db.users.createIndex( { "username": "text" } )

Then, to search:

db.users.find( { $text: { $search: "son" } } )

Benchmarks (~150K documents):

• Regex (other answers) => 5.6-6.9 seconds
• Text Search => .164-.201 seconds

Notes:

• A collection can have only one text index. You can use a wildcard text index if you want to search any string field, like this: db.collection.createIndex( { "$**": "text" } ).
• A text index can be large. It contains one index entry for each unique post-stemmed word in each indexed field for each document inserted.
• A text index will take longer to build than a normal index.
• A text index does not store phrases or information about the proximity of words in the documents. As a result, phrase queries will run much more effectively when the entire collection fits in RAM.

Seems like you're #inline_content isn't there! Remove the jQuery-Selector or check the parent elements, maybe you have a typo or forgot to add the id.

(made you a jsfiddle, works after adding a parent <div id="inline_content">: http://jsfiddle.net/J5HdN/)

To clarify, the above example does work, my code in the example did not work for unrelated reasons.

If myvar is false, null or has never been used before (i.e. $scope.myvar or $rootScope.myvar never called), the div will not show. Once any value has been assigned to it, the div will show, except if the value is specifically false.

The following will cause the div to show:

$scope.myvar = "Hello World";

or

$scope.myvar = true;

The following will hide the div:

$scope.myvar = null;

or

$scope.myvar = false;

In C# you cannot define true global variables (in the sense that they don't belong to any class).

This being said, the simplest approach that I know to mimic this feature consists in using a static class, as follows:

public static class Globals
{
    public const Int32 BUFFER_SIZE = 512; // Unmodifiable
    public static String FILE_NAME = "Output.txt"; // Modifiable
    public static readonly String CODE_PREFIX = "US-"; // Unmodifiable
}

You can then retrieve the defined values anywhere in your code (provided it's part of the same namespace):

String code = Globals.CODE_PREFIX + value.ToString();

In order to deal with different namespaces, you can either:

• declare the Globals class without including it into a specific namespace (so that it will be placed in the global application namespace);
• insert the proper using directive for retrieving the variables from another namespace.

You can always encrypt data on the client side. Please note that not all of the data have to be encrypted because it has a performance issue.

I know this question was asked 2 years ago, but I run into the same issue and the answer for the problem is since ES2017, that you can simply await the functions return value (as of now, only works in async functions), like:

let AuthUser = function(data) {
  return google.login(data.username, data.password).then(token => { return token } )
}

let userToken = await AuthUser(data)
console.log(userToken) // your data

If you want to install a bunch of dependencies from, say a requirements.txt, you would do:

mkdir dependencies
pip download -r requirements.txt -d "./dependencies"
tar cvfz dependencies.tar.gz dependencies

And, once you transfer the dependencies.tar.gz to the machine which does not have internet you would do:

tar zxvf dependencies.tar.gz
cd dependencies
pip install * -f ./ --no-index

please check if code below would work for you; it iterates through cells of the datagris's first column and checks if cell content equals to the textbox.text value and selects the row.

for (int i = 0; i < dataGrid.Items.Count; i++)
{
    DataGridRow row = (DataGridRow)dataGrid.ItemContainerGenerator.ContainerFromIndex(i);
    TextBlock cellContent = dataGrid.Columns[0].GetCellContent(row) as TextBlock;
    if (cellContent != null && cellContent.Text.Equals(textBox1.Text))
    {
        object item = dataGrid.Items[i];
        dataGrid.SelectedItem = item;
        dataGrid.ScrollIntoView(item);
        row.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
        break;
    }
}

hope this helps, regards

You can simply do the following inside your TR loop:

$(this).find('td').each (function() {
  // do your cool stuff
});                          

Use subDays() method:

$users = Users::where('status_id', 'active')
           ->where( 'created_at', '>', Carbon::now()->subDays(30))
           ->get();

Using shell_exec:

<?php
$output = shell_exec('ping -c1 google.com');
echo "<pre>$output</pre>";
?>

The differences are covered at the PostgreSQL documentation for date/time types. Yes, the treatment of TIME or TIMESTAMP differs between one WITH TIME ZONE or WITHOUT TIME ZONE. It doesn't affect how the values are stored; it affects how they are interpreted.

The effects of time zones on these data types is covered specifically in the docs. The difference arises from what the system can reasonably know about the value:

• With a time zone as part of the value, the value can be rendered as a local time in the client.

• Without a time zone as part of the value, the obvious default time zone is UTC, so it is rendered for that time zone.

The behaviour differs depending on at least three factors:

• The timezone setting in the client.
• The data type (i.e. WITH TIME ZONE or WITHOUT TIME ZONE) of the value.
• Whether the value is specified with a particular time zone.

Here are examples covering the combinations of those factors:

foo=> SET TIMEZONE TO 'Japan';
SET
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP;
      timestamp      
---------------------
 2011-01-01 00:00:00
(1 row)

foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP WITH TIME ZONE;
      timestamptz       
------------------------
 2011-01-01 00:00:00+09
(1 row)

foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP;
      timestamp      
---------------------
 2011-01-01 00:00:00
(1 row)

foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP WITH TIME ZONE;
      timestamptz       
------------------------
 2011-01-01 06:00:00+09
(1 row)

foo=> SET TIMEZONE TO 'Australia/Melbourne';
SET
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP;
      timestamp      
---------------------
 2011-01-01 00:00:00
(1 row)

foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP WITH TIME ZONE;
      timestamptz       
------------------------

foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP;

foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP WITH TIME ZONE;

You probably are looking for find_in_set function:

Where find_in_set($needle,'column') > 0

This function acts like in_array function in PHP

It is important to remember that React expects STABLE keys, meaning you should assign the keys once and every item on your list should receive the same key every time, that way React can optimize around your data changes when it is reconciling the virtual DOM and decides which components need to re-render. So, if you are using UUID you need to do it at the data level, not at the UI level.

Also keep in mind you can use any string you want for the key, so you can often combine several fields into one unique ID, something like ${username}_${timestamp} can be a fine unique key for a line in a chat, for example.

You could have the function take a variable as the first arg and modify the variable with the string you want to return.

#!/bin/bash
set -x
function pass_back_a_string() {
    eval "$1='foo bar rab oof'"
}

return_var=''
pass_back_a_string return_var
echo $return_var

Prints "foo bar rab oof".

Edit: added quoting in the appropriate place to allow whitespace in string to address @Luca Borrione's comment.

Edit: As a demonstration, see the following program. This is a general-purpose solution: it even allows you to receive a string into a local variable.

#!/bin/bash
set -x
function pass_back_a_string() {
    eval "$1='foo bar rab oof'"
}

return_var=''
pass_back_a_string return_var
echo $return_var

function call_a_string_func() {
     local lvar=''
     pass_back_a_string lvar
     echo "lvar='$lvar' locally"
}

call_a_string_func
echo "lvar='$lvar' globally"

This prints:

+ return_var=
+ pass_back_a_string return_var
+ eval 'return_var='\''foo bar rab oof'\'''
++ return_var='foo bar rab oof'
+ echo foo bar rab oof
foo bar rab oof
+ call_a_string_func
+ local lvar=
+ pass_back_a_string lvar
+ eval 'lvar='\''foo bar rab oof'\'''
++ lvar='foo bar rab oof'
+ echo 'lvar='\''foo bar rab oof'\'' locally'
lvar='foo bar rab oof' locally
+ echo 'lvar='\'''\'' globally'
lvar='' globally

Edit: demonstrating that the original variable's value is available in the function, as was incorrectly criticized by @Xichen Li in a comment.

#!/bin/bash
set -x
function pass_back_a_string() {
    eval "echo in pass_back_a_string, original $1 is \$$1"
    eval "$1='foo bar rab oof'"
}

return_var='original return_var'
pass_back_a_string return_var
echo $return_var

function call_a_string_func() {
     local lvar='original lvar'
     pass_back_a_string lvar
     echo "lvar='$lvar' locally"
}

call_a_string_func
echo "lvar='$lvar' globally"

This gives output:

+ return_var='original return_var'
+ pass_back_a_string return_var
+ eval 'echo in pass_back_a_string, original return_var is $return_var'
++ echo in pass_back_a_string, original return_var is original return_var
in pass_back_a_string, original return_var is original return_var
+ eval 'return_var='\''foo bar rab oof'\'''
++ return_var='foo bar rab oof'
+ echo foo bar rab oof
foo bar rab oof
+ call_a_string_func
+ local 'lvar=original lvar'
+ pass_back_a_string lvar
+ eval 'echo in pass_back_a_string, original lvar is $lvar'
++ echo in pass_back_a_string, original lvar is original lvar
in pass_back_a_string, original lvar is original lvar
+ eval 'lvar='\''foo bar rab oof'\'''
++ lvar='foo bar rab oof'
+ echo 'lvar='\''foo bar rab oof'\'' locally'
lvar='foo bar rab oof' locally
+ echo 'lvar='\'''\'' globally'
lvar='' globally

The java compiler tries to interpret 600851475143 as a constant value of type int by default. This causes an error since 600851475143 can not be represented with an int.

To tell the compiler that you want the number interpretet as a long you have to add either l or L after it. Your number should then look like this 600851475143L.

Since some Fonts make it hard to distinguish "1" and lower case "l" from each other you should always use the upper case "L".

Commenting just so people can have a solution to the intended question.

You can do what you are wanting but it isn't quite as nice as Notepad++ but it may work for small solutions decently enough.

In sublime if you hold ctrl, or mac equiv., and select the word/characters you want on a single line with the mouse and still holding ctrl go to another line and select the word/characters you want on that line it will be additive and you will build your selection. I mainly use notepadd++ as my extractor and data cleanup and sublime for actual development.

The other way is if your columns are in perfect alignment you can simply middle click on windows or option + click on mac and this enables you to select text in a square like fashion, Columns, inside the lines of text.

I was working with a class that did not contain a reference to the context. So it was not possible for me to use runOnUIThread(); I used view.post(); and it was solved.

timer.scheduleAtFixedRate(new TimerTask() {

    @Override
    public void run() {
        final int currentPosition = mediaPlayer.getCurrentPosition();
        audioMessage.seekBar.setProgress(currentPosition / 1000);
        audioMessage.tvPlayDuration.post(new Runnable() {
            @Override
            public void run() {
                audioMessage.tvPlayDuration.setText(ChatDateTimeFormatter.getDuration(currentPosition));
            }
        });
    }
}, 0, 1000);

The Tuple approach :

This solution provides a strict FixedLengthArray (ak.a. SealedArray) type signature based in Tuples.

Syntax example :

// Array containing 3 strings
let foo : FixedLengthArray<[string, string, string]> 

This is the safest approach, considering it prevents accessing indexes out of the boundaries.

Implementation :

type ArrayLengthMutationKeys = 'splice' | 'push' | 'pop' | 'shift' | 'unshift' | number
type ArrayItems<T extends Array<any>> = T extends Array<infer TItems> ? TItems : never
type FixedLengthArray<T extends any[]> =
  Pick<T, Exclude<keyof T, ArrayLengthMutationKeys>>
  & { [Symbol.iterator]: () => IterableIterator< ArrayItems<T> > }

Tests :

var myFixedLengthArray: FixedLengthArray< [string, string, string]>

// Array declaration tests
myFixedLengthArray = [ 'a', 'b', 'c' ]  // ? OK
myFixedLengthArray = [ 'a', 'b', 123 ]  // ? TYPE ERROR
myFixedLengthArray = [ 'a' ]            // ? LENGTH ERROR
myFixedLengthArray = [ 'a', 'b' ]       // ? LENGTH ERROR

// Index assignment tests 
myFixedLengthArray[1] = 'foo'           // ? OK
myFixedLengthArray[1000] = 'foo'        // ? INVALID INDEX ERROR

// Methods that mutate array length
myFixedLengthArray.push('foo')          // ? MISSING METHOD ERROR
myFixedLengthArray.pop()                // ? MISSING METHOD ERROR

// Direct length manipulation
myFixedLengthArray.length = 123         // ? READ-ONLY ERROR

// Destructuring
var [ a ] = myFixedLengthArray          // ? OK
var [ a, b ] = myFixedLengthArray       // ? OK
var [ a, b, c ] = myFixedLengthArray    // ? OK
var [ a, b, c, d ] = myFixedLengthArray // ? INVALID INDEX ERROR

(*) This solution requires the noImplicitAny typescript configuration directive to be enabled in order to work (commonly recommended practice)

The Array(ish) approach :

This solution behaves as an augmentation of the Array type, accepting an additional second parameter(Array length). Is not as strict and safe as the Tuple based solution.

Syntax example :

let foo: FixedLengthArray<string, 3> 

Keep in mind that this approach will not prevent you from accessing an index out of the declared boundaries and set a value on it.

Implementation :

type ArrayLengthMutationKeys = 'splice' | 'push' | 'pop' | 'shift' |  'unshift'
type FixedLengthArray<T, L extends number, TObj = [T, ...Array<T>]> =
  Pick<TObj, Exclude<keyof TObj, ArrayLengthMutationKeys>>
  & {
    readonly length: L 
    [ I : number ] : T
    [Symbol.iterator]: () => IterableIterator<T>   
  }

Tests :

var myFixedLengthArray: FixedLengthArray<string,3>

// Array declaration tests
myFixedLengthArray = [ 'a', 'b', 'c' ]  // ? OK
myFixedLengthArray = [ 'a', 'b', 123 ]  // ? TYPE ERROR
myFixedLengthArray = [ 'a' ]            // ? LENGTH ERROR
myFixedLengthArray = [ 'a', 'b' ]       // ? LENGTH ERROR

// Index assignment tests 
myFixedLengthArray[1] = 'foo'           // ? OK
myFixedLengthArray[1000] = 'foo'        // ? SHOULD FAIL

// Methods that mutate array length
myFixedLengthArray.push('foo')          // ? MISSING METHOD ERROR
myFixedLengthArray.pop()                // ? MISSING METHOD ERROR

// Direct length manipulation
myFixedLengthArray.length = 123         // ? READ-ONLY ERROR

// Destructuring
var [ a ] = myFixedLengthArray          // ? OK
var [ a, b ] = myFixedLengthArray       // ? OK
var [ a, b, c ] = myFixedLengthArray    // ? OK
var [ a, b, c, d ] = myFixedLengthArray // ? SHOULD FAIL

Probably this bug https://code.google.com/p/chromium/issues/detail?id=278361

This is reproduced with my Chrome 31.0.1650.57 (Official Build 235101) on Linux.

I'm restarting browser to fix it.

FYI, strcmp() and stricmp() are vulnerable to buffer overflow, since they just process until they hit a null terminator. It's safer to use _strncmp() and _strnicmp().

Is there a way to initialize the EntityManager without a persistence unit defined?

You should define at least one persistence unit in the persistence.xml deployment descriptor.

Can you give all the required properties to create an Entitymanager?

• The name attribute is required. The other attributes and elements are optional. (JPA specification). So this should be more or less your minimal persistence.xml file:

<persistence>
    <persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
        SOME_PROPERTIES
    </persistence-unit>
</persistence>

In Java EE environments, the jta-data-source and non-jta-data-source elements are used to specify the global JNDI name of the JTA and/or non-JTA data source to be used by the persistence provider.

So if your target Application Server supports JTA (JBoss, Websphere, GlassFish), your persistence.xml looks like:

<persistence>
    <persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
        <!--GLOBAL_JNDI_GOES_HERE-->
        <jta-data-source>jdbc/myDS</jta-data-source>
    </persistence-unit>
</persistence>

If your target Application Server does not support JTA (Tomcat), your persistence.xml looks like:

<persistence>
    <persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
        <!--GLOBAL_JNDI_GOES_HERE-->
        <non-jta-data-source>jdbc/myDS</non-jta-data-source>
    </persistence-unit>
</persistence>

If your data source is not bound to a global JNDI (for instance, outside a Java EE container), so you would usually define JPA provider, driver, url, user and password properties. But property name depends on the JPA provider. So, for Hibernate as JPA provider, your persistence.xml file will looks like:

<persistence>
    <persistence-unit name="[REQUIRED_PERSISTENCE_UNIT_NAME_GOES_HERE]">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <class>br.com.persistence.SomeClass</class>
        <properties>
            <property name="hibernate.connection.driver_class" value="org.apache.derby.jdbc.ClientDriver"/>
            <property name="hibernate.connection.url" value="jdbc:derby://localhost:1527/EmpServDB;create=true"/>
            <property name="hibernate.connection.username" value="APP"/>
            <property name="hibernate.connection.password" value="APP"/>
        </properties>
    </persistence-unit>
</persistence>

Transaction Type Attribute

In general, in Java EE environments, a transaction-type of RESOURCE_LOCAL assumes that a non-JTA datasource will be provided. In a Java EE environment, if this element is not specified, the default is JTA. In a Java SE environment, if this element is not specified, a default of RESOURCE_LOCAL may be assumed.

• To insure the portability of a Java SE application, it is necessary to explicitly list the managed persistence classes that are included in the persistence unit (JPA specification)

I need to create the EntityManager from the user's specified values at runtime

So use this:

Map addedOrOverridenProperties = new HashMap();

// Let's suppose we are using Hibernate as JPA provider
addedOrOverridenProperties.put("hibernate.show_sql", true);

Persistence.createEntityManagerFactory(<PERSISTENCE_UNIT_NAME_GOES_HERE>, addedOrOverridenProperties);

To hide the prompt set xls.DisplayAlerts = False

ConflictResolution is not a true or false property, it should be xlLocalSessionChanges

Note that this has nothing to do with displaying the Overwrite prompt though!

Set xls = CreateObject("Excel.Application")    
xls.DisplayAlerts = False
Set wb = xls.Workbooks.Add
fullFilePath = importFolderPath & "\" & "A.xlsx"

wb.SaveAs fullFilePath, AccessMode:=xlExclusive,ConflictResolution:=Excel.XlSaveConflictResolution.xlLocalSessionChanges    
wb.Close (True)

Just add remove_button_css as class to your button tag. You can verify the code for Link 1

.remove_button_css { 
  outline: none;
  padding: 5px; 
  border: 0px; 
  box-sizing: none; 
  background-color: transparent; 
}

Extra Styles Edit

Add color: #337ab7; and :hover and :focus to match OOTB (bootstrap3)

.remove_button_css:focus,
.remove_button_css:hover {
    color: #23527c;
    text-decoration: underline;
}

$('p:after').css('display','none');

In my case in the module's build.gradle the mainClassName assignment must state the fully qualified class name, ie. as specified as the package name in the main class' source code file.

ZincX's solution adapted to include colon delimiters:

char buf[] = {0,1,10,11};
int i, size = sizeof(buf) / sizeof(char);
char *buf_str = (char*) malloc(3 * size), *buf_ptr = buf_str;
if (buf_str) {
  for (i = 0; i < size; i++)
    buf_ptr += sprintf(buf_ptr, i < size - 1 ? "%02X:" : "%02X\0", buf[i]);
  printf("%s\n", buf_str);
  free(buf_str);
}

As many people mentioned, using LD_PRELOAD to preload library. BTW, you can CHECK if the setting is available by ldd command.

Example: suppose you need to preload your own libselinux.so.1.

> ldd /bin/ls
    ...
    libselinux.so.1 => /lib/x86_64-linux-gnu/libselinux.so.1 (0x00007f3927b1d000)
    libacl.so.1 => /lib/x86_64-linux-gnu/libacl.so.1 (0x00007f3927914000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f392754f000)
    libpcre.so.3 => /lib/x86_64-linux-gnu/libpcre.so.3 (0x00007f3927311000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f392710c000)
    /lib64/ld-linux-x86-64.so.2 (0x00007f3927d65000)
    libattr.so.1 => /lib/x86_64-linux-gnu/libattr.so.1 (0x00007f3926f07000)

Thus, set your preload environment:

  export LD_PRELOAD=/home/patric/libselinux.so.1

Check your library again:

>ldd /bin/ls
    ...
    libselinux.so.1 =>
    /home/patric/libselinux.so.1 (0x00007fb9245d8000)
    ...

the problem for me was I was trying to use IBM RAD which appears to not work properly for this, I installed Eclipse and now have a different error but I should be able to get past it

I know this thread is old, but since a Google search brought me here, it will also do to other people who may find this useful.

Microsoft recenly launched Visual Studio Online, which is free for projects with up to 5 users:

http://www.visualstudio.com/en-us/products/visual-studio-online-overview-vs.aspx

I have been using it for a while, and it integrates completely with Visual Studio 2013. It claims integration with other IDEs too. Apart from TFS, Git can also be used with it.

I know this thread is old, but since a Google search brought me here

How about try some different mirrors? If you are in China, I highly recommend you try:

sudo pip install --index https://pypi.mirrors.ustc.edu.cn/simple/ opencv-contrib-python

If not, just replace the url address to some other mirrors you like! Good luck.

Update

While my original answer below is still valid and might be helpful to understand the cause for DNS based URL forwarding not being available via Amazon Route 53 out of the box, I highly recommend checking out Vivek M. Chawla's utterly smart indirect solution via the meanwhile introduced Amazon S3 Support for Website Redirects and achieving a self contained server less and thus free solution within AWS only like so.

• Implementing an automated solution to generate such redirects is left as an exercise for the reader, but please pay tribute to Vivek's epic answer by publishing your solution ;)

Original Answer

Nettica must be running a custom redirection solution for this, here is the problem:

You could create a CNAME alias like aws.example.com for myaccount.signin.aws.amazon.com, however, DNS provides no official support for aliasing a subdirectory like console in this example.

• It's a pity that AWS doesn't appear to simply do this by default when hitting https://myaccount.signin.aws.amazon.com/ (I just tried), because it would solve you problem right away and make a lot of sense in the first place; besides, it should be pretty easy to configure on their end.

For that reason a few DNS providers have apparently implemented a custom solution to allow redirects to subdirectories; I venture the guess that they are basically facilitating a CNAME alias for a domain of their own and are redirecting again from there to the final destination via an immediate HTTP 3xx Redirection.

So to achieve the same result, you'd need to have a HTTP service running performing these redirects, which is not the simple solution one would hope for of course. Maybe/Hopefully someone can come up with a smarter approach still though.

The first parentheses are for, if you will, order of operations. The 'result' of the set of parentheses surrounding the function definition is the function itself which, indeed, the second set of parentheses executes.

As to why it's useful, I'm not enough of a JavaScript wizard to have any idea. :P

Another way to remove VBA project password is;

• Open xls file with a hex editor. (ie. Hex Edit http://www.hexedit.com/)
• Search for DPB
• Replace DPB to DPx
• Save file.
• Open file in Excel.
• Click "Yes" if you get any message box.
• Set new password from VBA Project Properties.
• Close and open again file, then type your new password to unprotect.

UPDATE: For Excel 2010 (Works for MS Office Pro Plus 2010 [14.0.6023.1000 64bit]),

• Open the XLSX file with 7zip

If workbook is protected:

• Browse the folder xl
• If the workbook is protected, right click workbook.xml and select Edit
• Find the portion <workbookProtection workbookPassword="XXXX" lockStructure="1"/> (XXXX is your encrypted password)
• Remove XXXX part. (ie. <workbookProtection workbookPassword="" lockStructure="1"/>)
• Save the file.
• When 7zip asks you to update the archive, say Yes.
• Close 7zip and re-open your XLSX.
• Click Protect Workbook on Review tab.
• Optional: Save your file.

If worksheets are protected:

• Browse to xl/worksheets/ folder.
• Right click the Sheet1.xml, sheet2.xml, etc and select Edit.
• Find the portion <sheetProtection password="XXXX" sheet="1" objects="1" scenarios="1" />
• Remove the encrypted password (ie. <sheetProtection password="" sheet="1" objects="1" scenarios="1" />)
• Save the file.
• When 7zip asks you to update the archive, say Yes.
• Close 7zip and re-open your XLSX.
• Click Unprotect Sheet on Review tab.
• Optional: Save your file.

You can re-activate the actions by adding

this.delegateEvents();  // Re-activates the events for all the buttons

If you add it to the render function of a backbone js view, then you can use event.preventDefault() as required.

$result->num_rows; only returns the number of row(s) affected by a query. When you are performing a count(*) on a table it only returns one row so you can not have an other result than 1.

You can invoke reflections and also, set order of sequence for getter for values through annotations

About promise composition vs. Rxjs, as this is a frequently asked question, you can refer to a number of previously asked questions on SO, among which :

• How to do the chain sequence in rxjs
• RxJS Promise Composition (passing data)
• RxJS sequence equvalent to promise.then()?

Basically, flatMap is the equivalent of Promise.then.

For your second question, do you want to replay values already emitted, or do you want to process new values as they arrive? In the first case, check the publishReplay operator. In the second case, standard subscription is enough. However you might need to be aware of the cold. vs. hot dichotomy depending on your source (cf. Hot and Cold observables : are there 'hot' and 'cold' operators? for an illustrated explanation of the concept)

If you are on CloudFlare, make sure you use something like this.

# BEGIN SSL Redirect
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
# END SSL Redirect

This will save you from the redirect loop and will redirect your site to SSL safely.

P.S. It is a good idea to if check the mod_rewrite.c!

Got a solution that runs. Don't know if it is optimal though. What I do is to split the string according to http://blogs.oracle.com/aramamoo/2010/05/how_to_split_comma_separated_string_and_pass_to_in_clause_of_select_statement.html

Using:
select regexp_substr(' 1, 2 , 3 ','[^,]+', 1, level) from dual
connect by regexp_substr('1 , 2 , 3 ', '[^,]+', 1, level) is not null;

So my final code looks like this ($bp_gr1' are strings like 1,2,3):

Is there a way to make it run faster?

• If you just want to sort the array values and don't care for the keys, use sort(). This will give a new array with numeric keys starting from 0.
• If you want to keep the key-value associations, use asort().

See also the comparison table of sorting functions in PHP.

Try like this

String sql = "SELECT t FROM table t";
Query query = em.createQuery(sql);
query.setFirstResult(firstPosition);
query.setMaxResults(numberOfRecords);
List result = query.getResultList();

It should work

UPDATE*

You can also try like this

query.setMaxResults(1).getResultList();

This will work:

#div{
     max-height:300px;
     overflow:hidden;
}
#div:hover{
     overflow-y:scroll;
}

You can compare class tokens to each other, so you could use value.getClass() == Integer.class. However, the simpler and more canonical way is to use instanceof :

    if (value instanceof Integer) {
        System.out.println("This is an Integer");
    } else if(value instanceof String) {
        System.out.println("This is a String");
    } else if(value instanceof Float) {
        System.out.println("This is a Float");
    }

Notes:

• the only difference between the two is that comparing class tokens detects exact matches only, while instanceof C matches for subclasses of C too. However, in this case all the classes listed are final, so they have no subclasses. Thus instanceof is probably fine here.

• as JB Nizet stated, such checks are not OO design. You may be able to solve this problem in a more OO way, e.g.

  System.out.println("This is a(n) " + value.getClass().getSimpleName());
  

You don't need to escape it inside. You can use the | character to delimit searches.

Hendry's answer is 100% correct. I had the same problem with my application, where there is repository project dealing with database with use of methods encapsulating EF db context operation. Other projects use this repository, and I don't want to reference EF in those projects. Somehow I don't feel it's proper, I need EF only in repository project. Anyway, copying EntityFramework.SqlServer.dll to other project output directory solves the problem. To avoid problems, when you forget to copy this dll, you can change repository build directory. Go to repository project's properties, select Build tab, and in output section you can set output directory to other project's build directory. Sure, it's just workaround. Maybe the hack, mentioned in some placec, is better:

var instance = System.Data.Entity.SqlServer.SqlProviderServices.Instance;

Still, for development purposes it is enough. Later, when preparing install or publish, you can add this file to package.

I'm quite new to EF. Is there any better method to solve this issue? I don't like "hack" - it makes me feel that there is something that is "not secure".

Not programming related, but I'll answer anyway. It's in /etc/hosts.

You can change it with a simple text editor such as nano.

(Obviously you would need a jailbroken iphone for this)

• Short answer: for "can't find dependent library" error, check your $PATH (corresponds to bullet point #3 below)
• Long answer:
  1. Pure java world: jvm uses "Classpath" to find class files
  2. JNI world (java/native boundary): jvm uses "java.library.path" (which defaults to $PATH) to find dlls
  3. pure native world: native code uses $PATH to load other dlls

I just tried to make a transparent image with powerpoint after failing miserably with other online systems. I was successful. Amazing.

First I used word art to give me typefaces which convert well to PNG or JPEG. The ordinary text in powerpoint does not convert well. It gets fuzzy. Anyway, I typed in my words in white (my choice of colour as i wanted it against a navy blue background), arranged it how i wanted, then right clicked and selected format shape to remove lines, then shadow to set the transparency.

I took the transparency to 100%. It came out fine. i then right clicked to save as png. Opened the image with MS Picture manager and resized the image to my suiting. It did not come out with the powerpoint white background at all. Once resized, i dropped the image against my navy blue background and it was like magic.

round(float("123.789"))

will give you an integer value, but a float type. With Python's duck typing, however, the actual type is usually not very relevant. This will also round the value, which you might not want. Replace 'round' with 'int' and you'll have it just truncated and an actual int. Like this:

int(float("123.789"))

But, again, actual 'type' is usually not that important.

In the event that Chrome detects SSL connection timeouts, certificate errors, or other network issues that might be caused by a captive portal (a hotel's WiFi network, for instance), Chrome will make a cookieless request to http://www.gstatic.com/generate_204 and check the response code. If that request is redirected, Chrome will open the redirect target in a new tab on the assumption that it's a login page. Requests to the captive portal detection page are not logged.

There is an 'exceptions' window in VS2005 ... try Ctrl+Alt+E when debugging and click on the 'Thrown' checkbox for the exception you want to stop on.

With react-router v2.8.1 (probably other 2.x.x versions as well, but I haven't tested it) you can use this implementation to do a Router redirect.

import { Router } from 'react-router';

export default class Foo extends Component {

  static get contextTypes() {
    return {
      router: React.PropTypes.object.isRequired,
    };
  }

  handleClick() {
    this.context.router.push('/some-path');
  }
}

I can see the that the others answers shown above are right, but I'll make your life easy.

I even created an example for you. I added some rows and want delete them.

You have to right click on the table and as shown in the figure Script Table a> Delete to> New query Editor widows:

Then another window will open with a script. Delete the line of "where", because you want to delete all rows. Then click Execute.

To make sure you did it right right click over the table and click in "Select Top 1000 rows". Then you can see that the query is empty.

This might not be an ethical and preferred solution but it helps in environments where you can't access the console to kill the job using yarn application command.

Steps are

Go to application master page of spark job. Click on the jobs section. Click on the active job's active stage. You will see "kill" button right next to the active stage.

This works if the succeeding stages are dependent on the currently running stage. Though it marks job as " Killed By User"

When you set maven scope as provided, it means that when the plugin runs, the actual dependencies version used will depend on the version of Apache Maven you have installed.

I wrote a little groovy version that you can run

it matches the following URLs (which is good enough for me)

public static void main(args) {
    String url = "go to http://www.m.abut.ly/abc its awesome"
    url = url.replaceAll(/https?:\/\/w{0,3}\w*?\.(\w*?\.)?\w{2,3}\S*|www\.(\w*?\.)?\w*?\.\w{2,3}\S*|(\w*?\.)?\w*?\.\w{2,3}[\/\?]\S*/ , { it ->
        "woof${it}woof"
    })
    println url 
}

http://google.com/help.php
http://google.com/help.php?a=5

http://www.google.com
http://www.google.com/help.php
http://www.google.com?a=5

google.com?a=5
google.com/help.php
google.com/help.php?a=5

http://www.m.google.com/help.php?a=5 (and all its permutations)
www.m.google.com/help.php?a=5 (and all its permutations)
m.google.com/help.php?a=5 (and all its permutations)

The important thing for any URLs that don't start with http or www is that they must include a / or ?

I bet this can be tweaked a little more but it does the job pretty nice for being so short and compact... because you can pretty much split it in 3:

find anything that starts with http:

https?:\/\/w{0,3}\w*?\.\w{2,3}\S*

find anything that starts with www:

www\.\w*?\.\w{2,3}\S*

or find anything that must have a text then a dot then at least 2 letters and then a ? or /:

\w*?\.\w{2,3}[\/\?]\S*

If there is anyone like me who is experiencing this issue using Vue.js, simply adding .prevent will do the trick: @click.prevent="someAction"

Groovy accepts nearly all Java syntax, so there is a spectrum of choices, as illustrated below:

// Java syntax 

Map<String,List> map1  = new HashMap<>();
List list1 = new ArrayList();
list1.add("hello");
map1.put("abc", list1); 
assert map1.get("abc") == list1;

// slightly less Java-esque

def map2  = new HashMap<String,List>()
def list2 = new ArrayList()
list2.add("hello")
map2.put("abc", list2)
assert map2.get("abc") == list2

// typical Groovy

def map3  = [:]
def list3 = []
list3 << "hello"
map3.'abc'= list3
assert map3.'abc' == list3

Pass a duration to show() and hide():

When a duration is provided, .show() becomes an animation method.

E.g. element.delay(1000).show(0)

DEMO

$("#filter").click(function(){
    //Put your code here
});

You can handle the Firefox driver automatically using WebDriverManager.

This library downloads the proper binary (geckodriver) for your platform (Mac, Windows, Linux) and then exports the proper value of the required Java environment variable (webdriver.gecko.driver).

Take a look at a complete example as a JUnit test case:

public class FirefoxTest {

  private WebDriver driver;

  @BeforeClass
  public static void setupClass() {
    WebDriverManager.firefoxdriver().setup();
  }

  @Before
  public void setupTest() {
    driver = new FirefoxDriver();
  }

  @After
  public void teardown() {
    if (driver != null) {
      driver.quit();
    }
  }

  @Test
  public void test() {
    // Your test code here
  }
}

If you are using Maven you have to put at your pom.xml:

<dependency>
    <groupId>io.github.bonigarcia</groupId>
    <artifactId>webdrivermanager</artifactId>
    <version>4.3.1</version>
</dependency>

WebDriverManager does magic for you:

1. It checks for the latest version of the WebDriver binary
2. It downloads the WebDriver binary if it's not present on your system
3. It exports the required WebDriver Java environment variables needed by Selenium

So far, WebDriverManager supports Chrome, Opera, Internet Explorer, Microsoft Edge, PhantomJS, and Firefox.

I've seen many answers with many votes advocating using the ternary operator. The ternary is great if a) you do have an alternative option and b) you are returning a fairly simple value from a simple condition. But...

The original question didn't have an alternative, and the ternary operator with only a single (real) branch forces you to return a confected answer.

lemons ? "foo gave me a bar" : "who knows what you'll get back"

I think the most common variation is lemons ? 'foo...' : '', and, as you'll know from reading the myriad of articles for any language on true, false, truthy, falsey, null, nil, blank, empty (with our without ?) , you are entering a minefield (albeit a well documented minefield.)

As soon as any part of the ternary gets complicated you are better off with a more explicit form of conditional.

A long way to say that I am voting for if (lemons) "foo".

This is a typical case of java.lang.StackOverflowError... The method is recursively calling itself with no exit in doubleValue(), floatValue(), etc.

The easiest method to modify the placeholder text color is through the XCode storyboard interface builder. Select the UITextField of interest and open the identity inspector on the right. Click on the plus symbol in the User Defined Runtime Attributes and add a new row with Key Path as _placeholderLabel.textColor, Type as Color and Value to your desired color.

It depends where you put this initialisation.

If the array is static as in

char array[100] = {0};

int main(void)
{
...
}

then it is the compiler that reserves the 100 0 bytes in the data segement of the program. In this case you could have omitted the initialiser.

If your array is auto, then it is another story.

int foo(void)
{
char array[100] = {0};
...
}

In this case at every call of the function foo you will have a hidden memset.

The code above is equivalent to

int foo(void)
{ 
char array[100];

memset(array, 0, sizeof(array));
....
}

and if you omit the initializer your array will contain random data (the data of the stack).

If your local array is declared static like in

int foo(void)
{ 
static char array[100] = {0};
...
}

then it is technically the same case as the first one.

I didnt see this question answered:

How should I setup a default Area when the application starts?

So, here is how you can set up a default Area:

var route = routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    ).DataTokens = new RouteValueDictionary(new { area = "MyArea" });

InnerHTML clear all data like event for existing nodes

append child with firstChild adds only first child to innerHTML. For example if we have to append:

 <p>text1</p><p>text2</p>

only text1 will show up

What about this:

adds special tag to innerHTML by append child and then edit outerHTML by deleting tag we've created. Don't know how smart it is but it works for me or you might change outerHTML to innerHTML so it doesn't have to use function replace

function append(element, str)_x000D_
{_x000D_
_x000D_
  var child = document.createElement('someshittyuniquetag');_x000D_
  _x000D_
  child.innerHTML = str;_x000D_
_x000D_
  element.appendChild(child);_x000D_
_x000D_
  child.outerHTML = child.outerHTML.replace(/<\/?someshittyuniquetag>/, '');_x000D_
_x000D_
// or Even child.outerHTML = child.innerHTML_x000D_
_x000D_
_x000D_
  _x000D_
}

<div id="testit">_x000D_
This text is inside the div_x000D_
<button onclick="append(document.getElementById('testit'), '<button>dadasasdas</button>')">To div</button>_x000D_
<button onclick="append(this, 'some text')">to this</button>_x000D_
</div>

The combined answer for writing to a file can be;

MemoryStream ms = new MemoryStream();    
FileStream file = new FileStream("file.bin", FileMode.Create, FileAccess.Write);
ms.WriteTo(file);
file.Close();
ms.Close();

Your command is completely incorrect. The output format is not rawvideo and you don't need the bitstream filter h264_mp4toannexb which is used when you want to convert the h264 contained in an mp4 to the Annex B format used by MPEG-TS for example. What you want to use instead is the aac_adtstoasc for the AAC streams.

ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

Format with Currency format string

=Format(Fields!Price.Value, "C")

It will give you 2 decimal places with "$" prefixed.

You can find other format strings on MSDN: Adding Style and Formatting to a ReportViewer Report

Note: The MSDN article has been archived to the "VS2005_General" document, which is no longer directly accessible online. Here is the excerpt of the formatting strings referenced:

Formatting Numbers

The following table lists common .NET Framework number formatting strings.

Format string, Name

C or c Currency

D or d Decimal

E or e Scientific

F or f Fixed-point

G or g General

N or n Number

P or p Percentage

R or r Round-trip

X or x Hexadecimal

You can modify many of the format strings to include a precision specifier that defines the number of digits to the right of the

decimal point. For example, a formatting string of D0 formats the number so that it has no digits after the decimal point. You

can also use custom formatting strings, for example, #,###.

Formatting Dates

The following table lists common .NET Framework date formatting strings.

Format string, Name

d Short date

D Long date

t Short time

T Long time

f Full date/time (short time)

F Full date/time (long time)

g General date/time (short time)

G General date/time (long time)

M or m Month day

You can also a use custom formatting strings; for example, dd/MM/yy. For more information about .NET Framework formatting strings, see Formatting Types.

First approach with Windows Service is not easy..

A long time ago, I wrote a C# service.

This is the logic of the Service class (tested, works fine):

namespace MyServiceApp
{
    public class MyService : ServiceBase
    {
        private System.Timers.Timer timer;

        protected override void OnStart(string[] args)
        {
            this.timer = new System.Timers.Timer(30000D);  // 30000 milliseconds = 30 seconds
            this.timer.AutoReset = true;
            this.timer.Elapsed += new System.Timers.ElapsedEventHandler(this.timer_Elapsed);
            this.timer.Start();
        }

        protected override void OnStop()
        {
            this.timer.Stop();
            this.timer = null;
        }

        private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            MyServiceApp.ServiceWork.Main(); // my separate static method for do work
        }

        public MyService()
        {
            this.ServiceName = "MyService";
        }

        // service entry point
        static void Main()
        {
            System.ServiceProcess.ServiceBase.Run(new MyService());
        }
    }
}

I recommend you write your real service work in a separate static method (why not, in a console application...just add reference to it), to simplify debugging and clean service code.

Make sure the interval is enough, and write in log ONLY in OnStart and OnStop overrides.

Hope this helps!

I've found Django's FileField to be really helpful for letting users upload and download files. The Django documentation has a section on managing files. You can store some information about the file in a table, along with a FileField that points to the file itself. Then you can list the available files by searching the table.

You cannot use a variable to access a property via dot notation, instead use the array notation.

var obj= {
     'name' : 'jroi'
};
var a = 'name';
alert(obj.a); //will not work
alert(obj[a]); //should work and alert jroi'

I think this is most suited:

Do the merging backward, for instance, if the committed code contains the revision from rev 5612 to 5616, just merge it backwards. It works in my end.

For instance:

svn merge -r 5616:5612 https://<your_svn_repository>/

It would contain a merged code back to former revision, then you could commit it.

It can be convenient to approach argument detection by evoking your function with an Object of optional properties:

function foo(options) {
    var config = { // defaults
        list: 'string value',
        of: [a, b, c],
        optional: {x: y},
        objects: function(param){
           // do stuff here
        }
    }; 
    if(options !== undefined){
        for (i in config) {
            if (config.hasOwnProperty(i)){
                if (options[i] !== undefined) { config[i] = options[i]; }
            }
        }
    }
}

var exists = $("#yourSelect option")
               .filter(function (i, o) { return o.value === yourValue; })
               .length > 0;

This has the advantage of automatically escaping the value for you, which makes random quotes in the text much easier to deal with.

This article sums it up pretty well

Summary: It's implementation dependent, as there is no specified limit in the RFC. It'd be safe to use up to 2000 characters (IE's limit.) If you are anywhere near this length, you should make sure you really need URIs that long, maybe an alternative design could get around that.

URIs should be readable, even when used to send data.

because of two way binding, To prevent error of:

ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was 
checked.

you can call a function to change model like this:

<input [ngModel]="item.value" 
  (ngModelChange)="getNewValue($event)" name="inputField" type="text" />


import { UseMyPipeToFormatThatValuePipe } from './path';

constructor({
    private UseMyPipeToFormatThatValue: UseMyPipeToFormatThatValuePipe,
})

getNewValue(ev: any): any {
    item.value= this.useMyPipeToFormatThatValue.transform(ev);
}

it'll be good if there is a better solution to prevent this error.

Use Map<Integer, List<String>>:

Map<Integer, List<String>> map = new LinkedHashMap< Integer, List<String>>();

map.put(-1505711364, new ArrayList<>(Arrays.asList("4")));
map.put(294357273, new ArrayList<>(Arrays.asList("15", "71")));
//...

To add a new key/value pair in this map:

public void add(Integer key, String newValue) {
    List<String> currentValue = map.get(key);
    if (currentValue == null) {
        currentValue = new ArrayList<String>();
        map.put(key, currentValue);
    }
    currentValue.add(newValue);
}

var table;

$(document).ready(function() {

    //datatables
    table = $('#userTable').DataTable({ 

        "processing": true, //Feature control the processing indicator.
        "serverSide": true, //Feature control DataTables' server-side processing mode.
        "order": [], //Initial no order.
         "aaSorting": [],
        // Load data for the table's content from an Ajax source
        "ajax": {
            "url": "<?php echo base_url().'admin/ajax_list';?>",
            "type": "POST"
        },

        //Set column definition initialisation properties.
        "columnDefs": [
        { 
            "targets": [ ], //first column / numbering column
            "orderable": false, //set not orderable
        },
        ],

    });

});

set

"targets": [0]

to

 "targets": [ ]

With JUnit 5.4, you can specify the order :

@Test
@Order(2)
public void sendEmailTestGmail() throws MessagingException {

you just need to annotate your class

@TestMethodOrder(OrderAnnotation.class)

https://junit.org/junit5/docs/current/user-guide/#writing-tests-test-execution-order

i'm using this in my project and it works very well !

There are many methods to this, here are some of them:

1. Using the predefined str method islower():

   >>> c = 'a'
   >>> c.islower()
   True
   

2. Using the ord() function to check whether the ASCII code of the letter is in the range of the ASCII codes of the lowercase characters:

   >>> c = 'a'
   >>> ord(c) in range(97, 123)
   True
   

3. Checking if the letter is equal to it's lowercase form:

   >>> c = 'a'
   >>> c.lower() == c
   True
   

4. Checking if the letter is in the list ascii_lowercase of the string module:

   >>> from string import ascii_lowercase
   >>> c = 'a'
   >>> c in ascii_lowercase
   True
   

But that may not be all, you can find your own ways if you don't like these ones: D.

Finally, let's start detecting:

d = str(input('enter a string : '))
lowers = [c for c in d if c.islower()]

# here i used islower() because it's the shortest and most-reliable
# one (being a predefined function), using this list comprehension
# is (probably) the most efficient way of doing this

Note: Android Studio spits out a load of crazy errors like this if you upgrade the support libraries to 28.0.0 and your compileSdkVersion is not 28 also.

try:

$("td[id^=" + value + "]")

You can even set the prof. pic size to its high resolution that is '1080x1080'

replace "150x150" with 1080x1080 and remove /vp/ from the link.

navigate to the folder where you have installed your kibana if you have used yum to install kibana it will be placed in following location by default

/usr/share/kibana

then use the following command

bin/kibana --version

Put this in the App.java:

public static void main(String[] args) throws UnknownHostException {
    SpringApplication app = new SpringApplication(App.class);
    SimpleCommandLinePropertySource source = new SimpleCommandLinePropertySource(args);
    if (!source.containsProperty("spring.profiles.active") &&
            !System.getenv().containsKey("SPRING_PROFILES_ACTIVE")) {

        app.setAdditionalProfiles("production");
    }
    ...
}

This is how it is done in JHipster

Extrapolating from Edwin's answer:

from math import ceil, floor
def float_round(num, places = 0, direction = floor):
    return direction(num * (10**places)) / float(10**places)

To use:

>>> float_round(0.21111, 3, ceil)  #round up
>>> 0.212
>>> float_round(0.21111, 3)        #round down
>>> 0.211
>>> float_round(0.21111, 3, round) #round naturally
>>> 0.211

use Node sleep package. https://www.npmjs.com/package/sleep.

in your code you can use

var sleep = require('sleep'); 
sleep.sleep(n)

to sleep for a specific n seconds.

There are plenty of ways to align with CSS, each one has it's benefits and disadvantages, you could test them all to check which one fits your case better: http://www.w3schools.com/css/css_align.asp

TIP: Always search using W3 as extra word, that will give you in first places the resources of the W3school website or the w3.org if there's any relevant.

matches(); does not buffer, but find() buffers. find() searches to the end of the string first, indexes the result, and return the boolean value and corresponding index.

That is why when you have a code like

1:Pattern.compile("[a-z]");

2:Pattern.matcher("0a1b1c3d4");

3:int count = 0;

4:while(matcher.find()){

5:count++: }

At 4: The regex engine using the pattern structure will read through the whole of your code (index to index as specified by the regex[single character] to find at least one match. If such match is found, it will be indexed then the loop will execute based on the indexed result else if it didn't do ahead calculation like which matches(); does not. The while statement would never execute since the first character of the matched string is not an alphabet.

To delete a cookie with JQuery, set the value to null:

$.cookie("name", null, { path: '/' });

Edit: The final solution was to explicitly specify the path property whenever accessing the cookie, because the OP accesses the cookie from multiple pages in different directories, and thus the default paths were different (this was not described in the original question). The solution was discovered in discussion below, which explains why this answer was accepted - despite not being correct.

For some versions jQ cookie the solution above will set the cookie to string null. Thus not removing the cookie. Use the code as suggested below instead.

$.removeCookie('the_cookie', { path: '/' });

Approach 1: You can use pandas' pd.get_dummies.

Example 1:

import pandas as pd
s = pd.Series(list('abca'))
pd.get_dummies(s)
Out[]: 
     a    b    c
0  1.0  0.0  0.0
1  0.0  1.0  0.0
2  0.0  0.0  1.0
3  1.0  0.0  0.0

Example 2:

The following will transform a given column into one hot. Use prefix to have multiple dummies.

import pandas as pd
        
df = pd.DataFrame({
          'A':['a','b','a'],
          'B':['b','a','c']
        })
df
Out[]: 
   A  B
0  a  b
1  b  a
2  a  c

# Get one hot encoding of columns B
one_hot = pd.get_dummies(df['B'])
# Drop column B as it is now encoded
df = df.drop('B',axis = 1)
# Join the encoded df
df = df.join(one_hot)
df  
Out[]: 
       A  a  b  c
    0  a  0  1  0
    1  b  1  0  0
    2  a  0  0  1

Approach 2: Use Scikit-learn

Using a OneHotEncoder has the advantage of being able to fit on some training data and then transform on some other data using the same instance. We also have handle_unknown to further control what the encoder does with unseen data.

Given a dataset with three features and four samples, we let the encoder find the maximum value per feature and transform the data to a binary one-hot encoding.

>>> from sklearn.preprocessing import OneHotEncoder
>>> enc = OneHotEncoder()
>>> enc.fit([[0, 0, 3], [1, 1, 0], [0, 2, 1], [1, 0, 2]])   
OneHotEncoder(categorical_features='all', dtype=<class 'numpy.float64'>,
   handle_unknown='error', n_values='auto', sparse=True)
>>> enc.n_values_
array([2, 3, 4])
>>> enc.feature_indices_
array([0, 2, 5, 9], dtype=int32)
>>> enc.transform([[0, 1, 1]]).toarray()
array([[ 1.,  0.,  0.,  1.,  0.,  0.,  1.,  0.,  0.]])

Here is the link for this example: http://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.OneHotEncoder.html

The role you have created is not allowed to log in. You have to give the role permission to log in.

One way to do this is to log in as the postgres user and update the role:

psql -U postgres

Once you are logged in, type:

ALTER ROLE "asunotest" WITH LOGIN;

Here's the documentation http://www.postgresql.org/docs/9.0/static/sql-alterrole.html

One way is to use window.print() function. Which does not require any library

Pros

1.No external library require.

2.We can print only selected parts of body also.

3.No css conflicts and js issues.

4.Core html/js functionality

---Simply add below code

CSS to

@media print {
        body * {
            visibility: hidden; // part to hide at the time of print
            -webkit-print-color-adjust: exact !important; // not necessary use         
               if colors not visible
        }

        #printBtn {
            visibility: hidden !important; // To hide 
        }

        #page-wrapper * {
            visibility: visible; // Print only required part
            text-align: left;
            -webkit-print-color-adjust: exact !important;
        }
    }

JS code - Call bewlow function on btn click

$scope.printWindow = function () {
  window.print()
}

Note: Use !important in every css object

Example -

.legend  {
  background: #9DD2E2 !important;
}

You may have imported,

project/controllers/base

inside the

project/controllers/routes

You have already imported before. That's not supported.

Sometime using some standard libraries helps a lot. Try to look at the Apache Commons Collections. In this case your problems is simply transformed to something like this

String[] keys = {"blah", "blahblah"}
Set<String> myEmptySet = new HashSet<String>();
CollectionUtils.addAll(pythonKeywordSet, keys);

And here is the CollectionsUtils javadoc

Try mpstat from the sysstat package

> sudo apt-get install sysstat
Linux 3.0.0-13-generic (ws025)  02/10/2012  _x86_64_    (2 CPU)  

03:33:26 PM  CPU    %usr   %nice    %sys %iowait    %irq   %soft  %steal  %guest   %idle
03:33:26 PM  all    2.39    0.04    0.19    0.34    0.00    0.01    0.00    0.00   97.03

Then some cutor grepto parse the info you need:

mpstat | grep -A 5 "%idle" | tail -n 1 | awk -F " " '{print 100 -  $ 12}'a

The most common reason I've had for a "broken pipe" is that one machine (of a pair communicating via socket) has shut down its end of the socket before communication was complete. About half of those were because the program communicating on that socket had terminated.

If the program sending bytes sends them out and immediately shuts down the socket or terminates itself, it is possible for the socket to cease functioning before the bytes have been transmitted and read.

Try putting pauses anywhere you are shutting down the socket and before you allow the program to terminate to see if that helps.

FYI: "pipe" and "socket" are terms that get used interchangeably sometimes.

HTML 5 does support iframes. There were a few interesting attributes added like "sandbox" and "srcdoc".

http://www.w3schools.com/html5/tag_iframe.asp

or you can use

<object data="framed.html" type="text/html"><p>This is the fallback code!</p></object>

C# equivalent of your code is

  class Imagedata : PDFStreamEngine
  {
     // C# uses "base" keyword whenever Java uses "super" 
     // so instead of super(...) in Java we should call its C# equivalent (base):
     public Imagedata()
       : base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true)) 
     { }

     // Java methods are virtual by default, when C# methods aren't.
     // So we should be sure that processOperator method in base class 
     // (that is PDFStreamEngine)
     // declared as "virtual"
     protected override void processOperator(PDFOperator operations, List arguments)
     {
        base.processOperator(operations, arguments);
     }
  }

The simplest way is use return View.

return View("ViewName");

Remember, the physical name of the "ViewName" should be something like ViewName.cshtml in your project, if your are using MVC C# / .NET.
