A similar approach to @Peter Coppins answer. This, I think, is a bit easier and doesn't require the use of the Orca utility:

1. Check the "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Common\FilesPaths" registry key and make sure the value "mso.dll" is NOT present. If it is present, then Office 64-bit seems to be installed and you should not need this workaround.

2. Download the Microsoft Access Database Engine 2010 Redistributable.

3. From the command line, run: AccessDatabaseEngine_x64.exe /passive

(Note: this installer silently crashed or failed for me, so I unzipped the components and ran: AceRedist.msi /passive and that installed fine. Maybe a Windows 10 thing.)

4. Delete or rename the "mso.dll" value in the "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Common\FilesPaths" key.

eta: There's a killer article on this stuff by SO's own @Nick Craver that you should read

While the other responses say this, they don't make it explicit, so I will....

On VS2013.2, to actually trigger the emission of the cited information, you need to not read the message, which says:

C:\Program Files (x86)\MSBuild\12.0\bin\Microsoft.Common.CurrentVersion.targets(1697,5): warning MSB3277: Found conflicts between different versions of the same dependent assembly that could not be resolved. These reference conflicts are listed in the build log when log verbosity is set to detailed.

This is incorrect (or at least it was for some versions of Visual Studio - it seems to be OK on an up to date VS2015 Update 3 or later). Instead turn it to Diagnostic (from Tools->Options->Project and Solutions->Build and Run, set MSBuild project build output verbosity), whereupon you'll see messages such as:

There was a conflict between "Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed" and "Newtonsoft.Json, Version=6.0.5.17707, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed".

• "Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed" was chosen because it was primary and "Newtonsoft.Json, Version=6.0.5.17707, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed" was not.

Then

• Ctrl-Alt-O to go to Build output window
• search for "was chosen" to find the drilldown.

...And yes, for those looking at the detail of the [diagnostic] message, it was news to this ignoramus that there's a convention in town whereby all 6.x versions are, internally Assembly Version 6.0.0.0, i.e. only the SemVer Major component goes into the Assembly Version :)

When using request for an http POST you can add parameters this way:

var request = require('request');
request.post({
  url:     'http://localhost/test2.php',
  form:    { mes: "heydude" }
}, function(error, response, body){
  console.log(body);
});

Not from activities only:

    public static String getStringByIdName(Context context, String idName) {
        Resources res = context.getResources();
        return res.getString(res.getIdentifier(idName, "string", context.getPackageName()));
    }

Recently I found a way around this. I wanted to create a method in the array class with an optional parameter, to keep or discard elements in the array.

The way I simulated this was by passing an array as the parameter, and then checking if the value at that index was nil or not.

class Array
  def ascii_to_text(params)
    param_len = params.length
    if param_len > 3 or param_len < 2 then raise "Invalid number of arguments #{param_len} for 2 || 3." end
    bottom  = params[0]
    top     = params[1]
    keep    = params[2]
    if keep.nil? == false
      if keep == 1
        self.map{|x| if x >= bottom and x <= top then x = x.chr else x = x.to_s end}
      else
        raise "Invalid option #{keep} at argument position 3 in #{p params}, must be 1 or nil"
      end
    else
      self.map{|x| if x >= bottom and x <= top then x = x.chr end}.compact
    end
  end
end

Trying out our class method with different parameters:

array = [1, 2, 97, 98, 99]
p array.ascii_to_text([32, 126, 1]) # Convert all ASCII values of 32-126 to their chr value otherwise keep it the same (That's what the optional 1 is for)

output: ["1", "2", "a", "b", "c"]

Okay, cool that works as planned. Now let's check and see what happens if we don't pass in the the third parameter option (1) in the array.

array = [1, 2, 97, 98, 99]
p array.ascii_to_text([32, 126]) # Convert all ASCII values of 32-126 to their chr value else remove it (1 isn't a parameter option)

output: ["a", "b", "c"]

As you can see, the third option in the array has been removed, thus initiating a different section in the method and removing all ASCII values that are not in our range (32-126)

Alternatively, we could had issued the value as nil in the parameters. Which would look similar to the following code block:

def ascii_to_text(top, bottom, keep = nil)
  if keep.nil?
    self.map{|x| if x >= bottom and x <= top then x = x.chr end}.compact
  else
    self.map{|x| if x >= bottom and x <= top then x = x.chr else x = x.to_s end}
end

To check if a folder contains at least one file

>nul 2>nul dir /a-d "folderName\*" && (echo Files exist) || (echo No file found)

To check if a folder or any of its descendents contain at least one file

>nul 2>nul dir /a-d /s "folderName\*" && (echo Files exist) || (echo No file found)

To check if a folder contains at least one file or folder.
Note addition of /a option to enable finding of hidden and system files/folders.

dir /b /a "folderName\*" | >nul findstr "^" && (echo Files and/or Folders exist) || (echo No File or Folder found)

To check if a folder contains at least one folder

dir /b /ad "folderName\*" | >nul findstr "^" && (echo Folders exist) || (echo No folder found)

You have to wait for TypeScript 2.0 with async/await for ES5 support as it now supported only for TS to ES6 compilation.

You would be able to create delay function with async:

function delay(ms: number) {
    return new Promise( resolve => setTimeout(resolve, ms) );
}

And call it

await delay(300);

Please note, that you can use await only inside async function.

If you can't (let's say you are building nodejs application), just place your code in the anonymous async function. Here is an example:

    (async () => { 
        // Do something before delay
        console.log('before delay')

        await delay(1000);

        // Do something after
        console.log('after delay')
    })();

Example TS Application: https://github.com/v-andrew/ts-template

In OLD JS you have to use

setTimeout(YourFunctionName, Milliseconds);

or

setTimeout( () => { /*Your Code*/ }, Milliseconds );

However with every major browser supporting async/await it less useful.

Update: TypeScript 2.1 is here with async/await.

Just do not forget that you need Promise implementation when you compile to ES5, where Promise is not natively available.

PS

You have to export the function if you want to use it outside of the original file.

As explained in Python's super() considered super, one way is to have class eat the arguments it requires, and pass the rest on. Thus, when the call-chain reaches object, all arguments have been eaten, and object.__init__ will be called without arguments (as it expects). So your code should look like this:

class A(object):
    def __init__(self, *args, **kwargs):
        print "A"
        super(A, self).__init__(*args, **kwargs)

class B(object):
    def __init__(self, *args, **kwargs):
        print "B"
        super(B, self).__init__(*args, **kwargs)

class C(A):
    def __init__(self, arg, *args, **kwargs):
        print "C","arg=",arg
        super(C, self).__init__(*args, **kwargs)

class D(B):
    def __init__(self, arg, *args, **kwargs):
        print "D", "arg=",arg
        super(D, self).__init__(*args, **kwargs)

class E(C,D):
    def __init__(self, arg, *args, **kwargs):
        print "E", "arg=",arg
        super(E, self).__init__(*args, **kwargs)

print "MRO:", [x.__name__ for x in E.__mro__]
E(10, 20, 30)

You should use the * operator, like foo(*values) Read the Python doc unpackaging argument lists.

Also, do read this: http://www.saltycrane.com/blog/2008/01/how-to-use-args-and-kwargs-in-python/

def foo(x,y,z):
   return "%d, %d, %d" % (x,y,z)

values = [1,2,3]

# the solution.
foo(*values)

You can do this as follows:

for (Direction direction : EnumSet.allOf(Direction.class)) {
  // do stuff
}

Considering that the accepted answer is probably inefficient for large arrays, O(nm), I usually prefer this approach, O(2n + 2m):

function mergeArrays(arr1 = [], arr2 = []){
    //Creates an object map of id to object in arr1
    const arr1Map = arr1.reduce((acc, o) => {
        acc[o.id] = o;
        return acc;
    }, {});
    //Updates the object with corresponding id in arr1Map from arr2, 
    //creates a new object if none exists (upsert)
    arr2.forEach(o => {
        arr1Map[o.id] = o;
    });

    //Return the merged values in arr1Map as an array
    return Object.values(arr1Map);
}

Unit test:

it('Merges two arrays using id as the key', () => {
   var arr1 = [{id:'124',name:'qqq'}, {id:'589',name:'www'}, {id:'45',name:'eee'}, {id:'567',name:'rrr'}];
   var arr2 = [{id:'124',name:'ttt'}, {id:'45',name:'yyy'}];
   const actual = mergeArrays(arr1, arr2);
   const expected = [{id:'124',name:'ttt'}, {id:'589',name:'www'}, {id:'45',name:'yyy'}, {id:'567',name:'rrr'}];
   expect(actual.sort((a, b) => (a.id < b.id)? -1: 1)).toEqual(expected.sort((a, b) => (a.id < b.id)? -1: 1));
})

You can use DBMS_PIPE.SEND_MESSAGE with a message that is too large for the pipe, for example for a 5 second delay write XXX to a pipe that can only accept one byte using a 5 second timeout as below

dbms_pipe.pack_message('XXX');<br>
dummy:=dbms_pipe.send_message('TEST_PIPE', 5, 1);

But then that requires a grant for DBMS_PIPE so perhaps no better.

Jenkins 1.x

The following groovy snippet should pass the version (as you've already supplied), and store it in the job's variables as 'miniVersion'.

import hudson.model.*

def env = System.getenv()
def version = env['currentversion']
def m = version =~/\d{1,2}/
def minVerVal = m[0]+"."+m[1]

def pa = new ParametersAction([
  new StringParameterValue("miniVersion", minVerVal)
])

// add variable to current job
Thread.currentThread().executable.addAction(pa)

The variable will then be accessible from other build steps. e.g.

echo miniVersion=%miniVersion%

Outputs:

miniVersion=12.34

I believe you'll need to use the "System Groovy Script" (on the Master node only) as opposed to the "Groovy Plugin" - https://wiki.jenkins-ci.org/display/JENKINS/Groovy+plugin#Groovyplugin-GroovyScriptvsSystemGroovyScript

Jenkins 2.x

I believe the previous (Jenkins 1.x) behaviour stopped working because of this Security Advisory...

Solution (paraphrased from the Security Advisory)

It's possible to restore the previous behaviour by setting the system property hudson.model.ParametersAction.keepUndefinedParameters to true. This is potentially very unsafe and intended as a short-term workaround only.

java -Dhudson.model.ParametersAction.keepUndefinedParameters=true -jar jenkins.war

To allow specific, known safe parameter names to be passed to builds, set the system property hudson.model.ParametersAction.safeParameters to a comma-separated list of safe parameter names.

e.g.

java -Dhudson.model.ParametersAction.safeParameters=miniVersion,FOO,BAR -jar jenkins.war

you can do it using aws cli : https://aws.amazon.com/cli/ and some unix command.

this aws cli commands should work:

aws s3 rm s3://<your_bucket_name> --exclude "*" --include "<your_regex>" 

if you want to include sub-folders you should add the flag --recursive

or with unix commands:

aws s3 ls s3://<your_bucket_name>/ | awk '{print $4}' | xargs -I%  <your_os_shell>   -c 'aws s3 rm s3:// <your_bucket_name>  /% $1'

explanation:

1. list all files on the bucket --pipe-->
2. get the 4th parameter(its the file name) --pipe--> // you can replace it with linux command to match your pattern
3. run delete script with aws cli

It may also be usefull to understand the difference in term of Session Bean Identity when using @EJB and @Inject. According to the specifications the following code will always be true:

@EJB Cart cart1;
@EJB Cart cart2;
… if (cart1.equals(cart2)) { // this test must return true ...}

Using @Inject instead of @EJB there is not the same.

see also stateless session beans identity for further info

Try this:

<style>
   #wrapper { position: relative; }
   #over_map { position: absolute; top: 10px; left: 10px; z-index: 99; }
</style>

<div id="wrapper">
   <div id="google_map">

   </div>

   <div id="over_map">

   </div>
</div>

Try: http://mvcjqgridcontrol.codeplex.com/ It's basically a MVC-compliant jQuery Grid wrapper with full .Net support

Like @benvie said, its more efficient to change a style sheet rather than using jQuery.css (which will loop through all of the elements in the set). It is also important not to add a new style to the head every time the function is called because it will create a memory leak and thousands of CSS rules that have to be individually applied by the browser. I would do something like this:

//Add the stylesheet once and store a cached jQuery object
var $style = $("<style type='text/css'>").appendTo('head'); 

function onResize() {
    var css = "\
        .someClass {\
            left:   "+leftVal+";\
            width:  "+widthVal+";\
            height: "+heightVal+";\
        }";

    $style.html(css);
}

This solution will change your styles by modifying the DOM only once per resize. Note that for effective js minification and compression, you probably don't want to pretty-print the css, but I did for clarity.

Make sure you didn't skip all jars in

tomcat.util.scan.StandardJarScanFilter.jarsToSkip

in Tomcat catalina.properties.

There is no global solution. For any given country it is at best rather tricky.

In the UK, the PostOffice controlls postal addresses, and can provide (at a cost) address information for validation purposes.

Government agencies also keep an extensive list of addresses, and these are centrally collated in the NLPG (National Land and Property Gazetteer).

Actually validating against these lists is very difficult. Most people don't even know exactly how their address as it is held by the PostOffice. Some businesses don't even know what number they are on a particular street.

Your best bet is to approach a company that specialises in this kind of thing.

Also you can use postgres fdw system

https://www.postgresql.org/docs/9.5/postgres-fdw.html

You will be able to connect different db in postgres. After that, in one query, you can access tables that are in different databases.

Those GCD functions provided by Commons-Math and Guava have some differences.

• Commons-Math throws an ArithematicException.class only for Integer.MIN_VALUE or Long.MIN_VALUE.
  • Otherwise, handles the value as an absolute value.
• Guava throws an IllegalArgumentException.class for any negative values.

Since the .length property is special for arrays in javascript you can simply say

obj.length === +obj.length // true if obj is an array

Underscorejs and several other libraries use this short and simple trick.

use this JavaScript code:

<script>
    setTimeout(function(){
       window.location.href = 'form2.html';
    }, 5000);
</script>

I wondered why this appeared during my unit tests.

I have added a method declaration to a protocol which included throws; but the potentially throwing method wasn't even used in that particular test. Enabling Zombies in test sounded like too much trouble.

Turns out a ?K clean did the trick. I'm always flabberghasted when that solves actual problems.

I came to add:

map(str.strip, string.split(','))

but saw it had already been mentioned by Jason Orendorff in a comment.

Reading Glenn Maynard's comment in the same answer suggesting list comprehensions over map I started to wonder why. I assumed he meant for performance reasons, but of course he might have meant for stylistic reasons, or something else (Glenn?).

So a quick (possibly flawed?) test on my box applying the three methods in a loop revealed:

[word.strip() for word in string.split(',')]
$ time ./list_comprehension.py 
real    0m22.876s

map(lambda s: s.strip(), string.split(','))
$ time ./map_with_lambda.py 
real    0m25.736s

map(str.strip, string.split(','))
$ time ./map_with_str.strip.py 
real    0m19.428s

making map(str.strip, string.split(',')) the winner, although it seems they are all in the same ballpark.

Certainly though map (with or without a lambda) should not necessarily be ruled out for performance reasons, and for me it is at least as clear as a list comprehension.

Edit:

Python 2.6.5 on Ubuntu 10.04

A more general function to encode an array is:

/**
 * also for multidemensional arrays
 *
 * @param array $array
 * @param string $sourceEncoding
 * @param string $destinationEncoding
 *
 * @return array
 */
function encodeArray(array $array, string $sourceEncoding, string $destinationEncoding = 'UTF-8'): array
{
    if($sourceEncoding === $destinationEncoding){
        return $array;
    }

    array_walk_recursive($array,
        function(&$array) use ($sourceEncoding, $destinationEncoding) {
            $array = mb_convert_encoding($array, $destinationEncoding, $sourceEncoding);
        }
    );

    return $array;
}

If you have several figures or subplots that you want to modify, it can be helpful to use the matplotlib context manager to change the color, instead of changing each one individually. The context manager allows you to temporarily change the rc parameters only for the immediately following indented code, but does not affect the global rc parameters.

This snippet yields two figures, the first one with modified colors for the axis, ticks and ticklabels, and the second one with the default rc parameters.

import matplotlib.pyplot as plt
with plt.rc_context({'axes.edgecolor':'orange', 'xtick.color':'red', 'ytick.color':'green', 'figure.facecolor':'white'}):
    # Temporary rc parameters in effect
    fig, (ax1, ax2) = plt.subplots(1,2)
    ax1.plot(range(10))
    ax2.plot(range(10))
# Back to default rc parameters
fig, ax = plt.subplots()
ax.plot(range(10))

You can type plt.rcParams to view all available rc parameters, and use list comprehension to search for keywords:

# Search for all parameters containing the word 'color'
[(param, value) for param, value in plt.rcParams.items() if 'color' in param]

The other way to fix this in other circumstances is to use NODE_TLS_REJECT_UNAUTHORIZED=0 as an environment variable

NODE_TLS_REJECT_UNAUTHORIZED=0 node server.js

WARNING: This is a bad idea security-wise

For me, one neat way to do this is to show a SnackBar at the bottom while the Signing-In process is taken place, this is a an example of what I mean:

Here is how to setup the SnackBar.

Define a global key for your Scaffold

final GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();

Add it to your Scaffold key attribute

return new Scaffold(
      key: _scaffoldKey,
.......

My SignIn button onPressed callback:

onPressed: () {
                  _scaffoldKey.currentState.showSnackBar(
                      new SnackBar(duration: new Duration(seconds: 4), content:
                      new Row(
                        children: <Widget>[
                          new CircularProgressIndicator(),
                          new Text("  Signing-In...")
                        ],
                      ),
                      ));
                  _handleSignIn()
                      .whenComplete(() =>
                      Navigator.of(context).pushNamed("/Home")
                  );
                }

It really depends on how you want to build your layout, and I am not sure what you have in mind.

Edit

You probably want it this way, I have used a Stack to achieve this result and just show or hide my indicator based on onPressed

class TestSignInView extends StatefulWidget {
  @override
  _TestSignInViewState createState() => new _TestSignInViewState();
}


class _TestSignInViewState extends State<TestSignInView> {
  bool _load = false;
  @override
  Widget build(BuildContext context) {
    Widget loadingIndicator =_load? new Container(
      color: Colors.grey[300],
      width: 70.0,
      height: 70.0,
      child: new Padding(padding: const EdgeInsets.all(5.0),child: new Center(child: new CircularProgressIndicator())),
    ):new Container();
    return new Scaffold(
      backgroundColor: Colors.white,
      body:  new Stack(children: <Widget>[new Padding(
        padding: const EdgeInsets.symmetric(vertical: 50.0, horizontal: 20.0),
        child: new ListView(

          children: <Widget>[
            new Column(
              mainAxisAlignment: MainAxisAlignment.center,
              crossAxisAlignment: CrossAxisAlignment.center
              ,children: <Widget>[
            new TextField(),
            new TextField(),

            new FlatButton(color:Colors.blue,child: new Text('Sign In'),
                onPressed: () {
              setState((){
                _load=true;
              });

                  //Navigator.of(context).push(new MaterialPageRoute(builder: (_)=>new HomeTest()));
                }
            ),

            ],),],
        ),),
        new Align(child: loadingIndicator,alignment: FractionalOffset.center,),

      ],));
  }

}

If the text contains \r\n that need to be converted into new lines use the 'Extended' or 'Regular expression' modes and escape the backslash character in 'Find what':

Find what: \\r\\n

Replace with: \r\n

this is works good https://gist.github.com/pablosalgadom/4d75f30517edc6230a67 for root user should edit

$ /etc/profile

but if you non root should put the generate code in the following

$ ~/.bash_profile

$ ~/.bash_login

$ ~/.profile

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

I would give your tds a specific class, e.g. data-cell, and then use something like this:

$("td.data-cell").each(function () {
    // 'this' is now the raw td DOM element
    var txt = $(this).html();
});

You should be able to use the Clear() method.

In your case, since you are only showing 3 columns:

Name    Value       Business
  or
Name    Business    Ecommerce Pro

why not set all 3 to have a width of 33.3%. since only 3 are ever shown at once, the browser should render them all a similar width.

So at the most basic level a HANDLE of any sort is a pointer to a pointer or

#define HANDLE void **

Now as to why you would want to use it

Lets take a setup:

class Object{
   int Value;
}

class LargeObj{

   char * val;
   LargeObj()
   {
      val = malloc(2048 * 1000);
   }

}

void foo(Object bar){
    LargeObj lo = new LargeObj();
    bar.Value++;
}

void main()
{
   Object obj = new Object();
   obj.val = 1;
   foo(obj);
   printf("%d", obj.val);
}

So because obj was passed by value (make a copy and give that to the function) to foo, the printf will print the original value of 1.

Now if we update foo to:

void foo(Object * bar)
{
    LargeObj lo = new LargeObj();
    bar->val++;
}

There is a chance that the printf will print the updated value of 2. But there is also the possibility that foo will cause some form of memory corruption or exception.

The reason is this while you are now using a pointer to pass obj to the function you are also allocating 2 Megs of memory, this could cause the OS to move the memory around updating the location of obj. Since you have passed the pointer by value, if obj gets moved then the OS updates the pointer but not the copy in the function and potentially causing problems.

A final update to foo of:

void foo(Object **bar){
    LargeObj lo = LargeObj();
    Object * b = &bar;
    b->val++;
}

This will always print the updated value.

See, when the compiler allocates memory for pointers it marks them as immovable, so any re-shuffling of memory caused by the large object being allocated the value passed to the function will point to the correct address to find out the final location in memory to update.

Any particular types of HANDLEs (hWnd, FILE, etc) are domain specific and point to a certain type of structure to protect against memory corruption.

On my Linux system (Red Hat Enterprise 6.9), the split command does not have the command-line options for either -n or --additional-suffix.

Instead, I've used this:

split -d -l NUM_LINES really_big_file.txt split_files.txt.

where -d is to add a numeric suffix to the end of the split_files.txt. and -l specifies the number of lines per file.

For example, suppose I have a really big file like this:

$ ls -laF
total 1391952
drwxr-xr-x 2 user.name group         40 Sep 14 15:43 ./
drwxr-xr-x 3 user.name group       4096 Sep 14 15:39 ../
-rw-r--r-- 1 user.name group 1425352817 Sep 14 14:01 really_big_file.txt

This file has 100,000 lines, and I want to split it into files with at most 30,000 lines. This command will run the split and append an integer at the end of the output file pattern split_files.txt..

$ split -d -l 30000 really_big_file.txt split_files.txt.

The resulting files are split correctly with at most 30,000 lines per file.

$ ls -laF
total 2783904
drwxr-xr-x 2 user.name group        156 Sep 14 15:43 ./
drwxr-xr-x 3 user.name group       4096 Sep 14 15:39 ../
-rw-r--r-- 1 user.name group 1425352817 Sep 14 14:01 really_big_file.txt
-rw-r--r-- 1 user.name group  428604626 Sep 14 15:43 split_files.txt.00
-rw-r--r-- 1 user.name group  427152423 Sep 14 15:43 split_files.txt.01

-rw-r--r-- 1 user.name group  142454325 Sep 14 15:43 split_files.txt.03


$ wc -l *.txt*

You could try converting it to an unsigned short and then print just the last four hex digits. The resulting value might be unique enough for your needs.

I found an other difference. if you do not define a constructor in a class, the compiler will define one. but in a struct if you do not define a constructor, the compiler do not define a constructor too. so in some cases that we really do not need a constructor, struct is a better choice (performance tip). and sorry for my bad English.

Memcached client library was just recently released as stable. It is being used by digg ( was developed for digg by Andrei Zmievski, now no longer with digg) and implements much more of the memcached protocol than the older memcache client. The most important features that memcached has are:

1. Cas tokens. This made my life much easier and is an easy preventive system for stale data. Whenever you pull something from the cache, you can receive with it a cas token (a double number). You can than use that token to save your updated object. If no one else updated the value while your thread was running, the swap will succeed. Otherwise a newer cas token was created and you are forced to reload the data and save it again with the new token.
2. Read through callbacks are the best thing since sliced bread. It has simplified much of my code.
3. getDelayed() is a nice feature that can reduce the time your script has to wait for the results to come back from the server.
4. While the memcached server is supposed to be very stable, it is not the fastest. You can use binary protocol instead of ASCII with the newer client.
5. Whenever you save complex data into memcached the client used to always do serialization of the value (which is slow), but now with memcached client you have the option of using igbinary. So far I haven't had the chance to test how much of a performance gain this can be.

All of this points were enough for me to switch to the newest client, and can tell you that it works like a charm. There is that external dependency on the libmemcached library, but have managed to install it nonetheless on Ubuntu and Mac OSX, so no problems there so far.

If you decide to update to the newer library, I suggest you update to the latest server version as well as it has some nice features as well. You will need to install libevent for it to compile, but on Ubuntu it wasn't much trouble.

I haven't seen any frameworks pick up the new memcached client thus far (although I don't keep track of them), but I presume Zend will get on board shortly.

UPDATE

Zend Framework 2 has an adapter for Memcached which can be found here

Setting the image using picture.ImageLocation() works fine, but you are using a relative path. Check your path against the location of the .exe after it is built.

For example, if your .exe is located at:

<project folder>/bin/Debug/app.exe

The image would have to be at:

<project folder>/bin/Image/1.jpg

Of course, you could just set the image at design-time (the Image property on the PictureBox property sheet).

If you must set it at run-time, one way to make sure you know the location of the image is to add the image file to your project. For example, add a new folder to your project, name it Image. Right-click the folder, choose "Add existing item" and browse to your image (be sure the file filter is set to show image files). After adding the image, in the property sheet set the Copy to Output Directory to Copy if newer.

At this point the image file will be copied when you build the application and you can use

picture.ImageLocation = @"Image\1.jpg"; 

for me with bootstrap 4 datetime picker (http://www.eyecon.ro/bootstrap-datepicker/) format worked only with upper case:

$('.datepicker').datetimepicker({
            format: 'DD/MM/YYYY'
        });

"Hello! world!".TrimEnd('!');

EDIT:

What I've noticed in this type of questions that quite everyone suggest to remove the last char of given string. But this does not fulfill the definition of Trim method.

Trim - Removes all occurrences of white space characters from the beginning and end of this instance.

MSDN-Trim

Under this definition removing only last character from string is bad solution.

So if we want to "Trim last character from string" we should do something like this

Example as extension method:

public static class MyExtensions
{
  public static string TrimLastCharacter(this String str)
  {
     if(String.IsNullOrEmpty(str)){
        return str;
     } else {
        return str.TrimEnd(str[str.Length - 1]);
     }
  }
}

Note if you want to remove all characters of the same value i.e(!!!!)the method above removes all existences of '!' from the end of the string, but if you want to remove only the last character you should use this :

else { return str.Remove(str.Length - 1); }

Adding another entry for the debate about whether batch normalization should be called before or after the non-linear activation:

In addition to the original paper using batch normalization before the activation, Bengio's book Deep Learning, section 8.7.1 gives some reasoning for why applying batch normalization after the activation (or directly before the input to the next layer) may cause some issues:

It is natural to wonder whether we should apply batch normalization to the input X, or to the transformed value XW+b. Io?e and Szegedy (2015) recommend the latter. More speci?cally, XW+b should be replaced by a normalized version of XW. The bias term should be omitted because it becomes redundant with the ß parameter applied by the batch normalization reparameterization. The input to a layer is usually the output of a nonlinear activation function such as the recti?ed linear function in a previous layer. The statistics of the input are thus more non-Gaussian and less amenable to standardization by linear operations.

In other words, if we use a relu activation, all negative values are mapped to zero. This will likely result in a mean value that is already very close to zero, but the distribution of the remaining data will be heavily skewed to the right. Trying to normalize that data to a nice bell-shaped curve probably won't give the best results. For activations outside of the relu family this may not be as big of an issue.

Keep in mind that there are reports of models getting better results when using batch normalization after the activation, while others get best results when the batch normalization is placed before the activation. It is probably best to test your model using both configurations, and if batch normalization after activation gives a significant decrease in validation loss, use that configuration instead.

If you can use JQuery, then using the JQuery :focus selector will do the needful

$(this).is(':focus');

npm install <packagename> --registry http://registry.npmjs.org/

Try specifying the registry with the install command. Solved my problem.

EDIT: Are you using canvas transforms? If so, you'll have to track the transformation matrix. The following method should measure the height of text with the initial transform.

EDIT #2: Oddly the code below does not produce correct answers when I run it on this StackOverflow page; it's entirely possible that the presence of some style rules could break this function.

The canvas uses fonts as defined by CSS, so in theory we can just add an appropriately styled chunk of text to the document and measure its height. I think this is significantly easier than rendering text and then checking pixel data and it should also respect ascenders and descenders. Check out the following:

var determineFontHeight = function(fontStyle) {
  var body = document.getElementsByTagName("body")[0];
  var dummy = document.createElement("div");
  var dummyText = document.createTextNode("M");
  dummy.appendChild(dummyText);
  dummy.setAttribute("style", fontStyle);
  body.appendChild(dummy);
  var result = dummy.offsetHeight;
  body.removeChild(dummy);
  return result;
};

//A little test...
var exampleFamilies = ["Helvetica", "Verdana", "Times New Roman", "Courier New"];
var exampleSizes = [8, 10, 12, 16, 24, 36, 48, 96];
for(var i = 0; i < exampleFamilies.length; i++) {
  var family = exampleFamilies[i];
  for(var j = 0; j < exampleSizes.length; j++) {
    var size = exampleSizes[j] + "pt";
    var style = "font-family: " + family + "; font-size: " + size + ";";
    var pixelHeight = determineFontHeight(style);
    console.log(family + " " + size + " ==> " + pixelHeight + " pixels high.");
  }
}

You'll have to make sure you get the font style correct on the DOM element that you measure the height of but that's pretty straightforward; really you should use something like

var canvas = /* ... */
var context = canvas.getContext("2d");
var canvasFont = " ... ";
var fontHeight = determineFontHeight("font: " + canvasFont + ";");
context.font = canvasFont;
/*
  do your stuff with your font and its height here.
*/

Create a stored procedure which takes two parameters a_begin and a_end. Create a temporary table within it called t, declare a variable d, assign a_begin to d, and run a WHILE loop INSERTing d into t and calling ADDDATE function to increment the value d. Finally SELECT * FROM t.

Set return type to Void instead of void and return null

// Modify existing method
public static Void displayInt(Integer i) {
    System.out.println(i);
    return null;
}

OR

// Or use Lambda
myForEach(theList, i -> {System.out.println(i);return null;});

You might set location directly because it's slightly shorter. If you're trying to be terse, you can usually omit the window. too.

URL assignments to both location.href and location are defined to work in JavaScript 1.0, back in Netscape 2, and have been implemented in every browser since. So take your pick and use whichever you find clearest.

It's specified in the function type. When you have a function pointer, it's assumed to be cdecl if not explicitly stdcall. This means that if you get a stdcall pointer and a cdecl pointer, you can't exchange them. The two function types can call each other without issues, it's just getting one type when you expect the other. As for speed, they both perform the same roles, just in a very slightly different place, it's really irrelevant.

Make your property "windowname" a DependencyProperty and keep the remaining same.

Array notation and pointer arithmetic can be used interchangeably in C/C++ (this is not true for ALL the cases but by the time you get there, you will find the cases yourself). So although str is a pointer, you can use it as if it were an array like so:

char char_E = str[1];
char char_L1 = str[2];
char char_O = str[4];

...and so on. What you could also do is "add" 1 to the value of the pointer to a character str which will then point to the second character in the string. Then you can simply do:

str = str + 1; // makes it point to 'E' now
char myChar =  *str;

I hope this helps.

you should check if it is less than 10... not looking for the length of it , because this is a number and not a string

I had the same error. The problem was this extra symbol ">" added by mistake between the tags </ComboBox.SelectedValue> and </ComboBox>:

<ComboBox 
   ItemsSource="{Binding StatusTypes}"
   DisplayMemberPath="StatusName"
   SelectedValuePath="StatusID">
   <ComboBox.SelectedValue>
      <Binding Path="StatusID"/>
   </ComboBox.SelectedValue>

</ComboBox>

and here is the correct code:

<ComboBox 
   ItemsSource="{Binding StatusTypes}"
   DisplayMemberPath="StatusName"
   SelectedValuePath="StatusID">
   <ComboBox.SelectedValue>
      <Binding Path="StatusID"/>
   </ComboBox.SelectedValue>

Install Django pylint:

pip install pylint-django

ctrl+shift+p > Preferences: Configure Language Specific Settings > Python

The settings.json available for python language should look like the below:

This is the simplest solution to limit the number of digits after decimal point to two:

myeditText2 = (EditText) findViewById(R.id.editText2);  
myeditText2.setInputType(3);

For Swift 2.0 and above you should apply reverse on a range collection

for i in (0 ..< 10).reverse() {
  // process
}

It has been renamed to .reversed() in Swift 3.0

I have a 7GB SQLite database. To perform a particular query with an inner join takes 2.6s In order to speed this up I tried adding indexes. Depending on which index(es) I added, sometimes the query went down to 0.1s and sometimes it went UP to as much as 7s. I think the problem in my case was that if a column is highly duplicate then adding an index degrades performance :(

The mktemp(1) man page explains it fairly well:

Traditionally, many shell scripts take the name of the program with the pid as a suffix and use that as a temporary file name. This kind of naming scheme is predictable and the race condition it creates is easy for an attacker to win. A safer, though still inferior, approach is to make a temporary directory using the same naming scheme. While this does allow one to guarantee that a temporary file will not be subverted, it still allows a simple denial of service attack. For these reasons it is suggested that mktemp be used instead.

In a script, I invoke mktemp something like

mydir=$(mktemp -d "${TMPDIR:-/tmp/}$(basename $0).XXXXXXXXXXXX")

which creates a temporary directory I can work in, and in which I can safely name the actual files something readable and useful.

mktemp is not standard, but it does exist on many platforms. The "X"s will generally get converted into some randomness, and more will probably be more random; however, some systems (busybox ash, for one) limit this randomness more significantly than others

By the way, safe creation of temporary files is important for more than just shell scripting. That's why python has tempfile, perl has File::Temp, ruby has Tempfile, etc…

The library I've used is ini4j. It is lightweight and parses the ini files with ease. Also it uses no esoteric dependencies to 10,000 other jar files, as one of the design goals was to use only the standard Java API

This is an example on how the library is used:

Ini ini = new Ini(new File(filename));
java.util.prefs.Preferences prefs = new IniPreferences(ini);
System.out.println("grumpy/homePage: " + prefs.node("grumpy").get("homePage", null));

For those who are looking for the quick one-liner:

plt.gca().set_yticklabels(['{:.0f}%'.format(x*100) for x in plt.gca().get_yticks()]) 

Or if you are using Latex as the axis text formatter, you have to add one backslash '\'

plt.gca().set_yticklabels(['{:.0f}\%'.format(x*100) for x in plt.gca().get_yticks()]) 

EDIT: After your comments, I understand that you want to pass variable through your form.

You can do this using hidden field:

<input type='hidden' name='var' value='<?php echo "$var";?>'/> 

In PHP action File:

<?php 
   if(isset($_POST['var'])) $var=$_POST['var'];
?>

Or using sessions: In your first page:

 $_SESSION['var']=$var;

start_session(); should be placed at the beginning of your php page.

In PHP action File:

if(isset($_SESSION['var'])) $var=$_SESSION['var'];

First Answer:

You can also use $GLOBALS :

if (isset($_POST['save_exit']))
{

   echo $GLOBALS['var']; 

}

Check this documentation for more informations.

<?php
$php_multi_array = array("lang"=>"PHP", "type"=>array("c_type"=>"MULTI", "p_type"=>"ARRAY"));

//Iterate through an array declared above

foreach($php_multi_array as $key => $value)
{
    if (!is_array($value))
    {
        echo $key ." => ". $value ."\r\n" ;
    }
    else
    {
       echo $key ." => array( \r\n";

       foreach ($value as $key2 => $value2)
       {
           echo "\t". $key2 ." => ". $value2 ."\r\n";
       }

       echo ")";
    }
}
?>

OUTPUT:

lang => PHP
type => array( 
    c_type => MULTI
    p_type => ARRAY
)

Reference Source Code

You could try with this for mime type

$image = getimagesize($_FILES['image']['tmp_name']);

$image['mime'] will return the mime type.

This function doesn't require GD library. You can find the documentation here.

This returns the mime type of the image.

Some people use the $_FILES["file"]["type"] but it's not reliable as been given by the browser and not by PHP.

You can use pathinfo() as ThiefMaster suggested to retrieve the image extension.

First make sure that the image is being uploaded successfully while in development before performing any operations with the image.

on the web site box, you have selected .NETFramework 4.5 and it doesn show, so click there and choose the 3.5...i hope it helps.

I did this to solve the same issue (in OS X):

1. Help > Install New Software > Add or select this repository "http://download.eclipse.org/eclipse/updates/4.3"
2. Under "Eclipse platform" select the newest version of Eclipse.
3. The installer will ask if you want to uninstall the ADT, click finish.
4. Restart Eclipse and install ONLY the ADT 23 using this repository: https://dl-ssl.google.com/android/eclipse.
5. Restart Eclipse and install DDMS, Hierarchy Viewer, Trace View etc.
6. Restart Eclipse again.

Hope it helps.

Don't know why but in my case it doesn't work the way suggested earlier. But it works like this:

Time.now.change(offset: "-3000")

Of course you need to change offset value to yours.

(this answer was added to provide shorter and more generic examples to the question - without including all the case-specific details in the original question).

There are two distinct "problems" here, the first is if a table or subquery has no rows, the second is if there are NULL values in the query.

For all versions I've tested, postgres and mysql will ignore all NULL values when averaging, and it will return NULL if there is nothing to average over. This generally makes sense, as NULL is to be considered "unknown". If you want to override this you can use coalesce (as suggested by Luc M).

$ create table foo (bar int);
CREATE TABLE

$ select avg(bar) from foo;
 avg 
-----

(1 row)

$ select coalesce(avg(bar), 0) from foo;
 coalesce 
----------
        0
(1 row)

$ insert into foo values (3);
INSERT 0 1
$ insert into foo values (9);
INSERT 0 1
$ insert into foo values (NULL);
INSERT 0 1
$ select coalesce(avg(bar), 0) from foo;
      coalesce      
--------------------
 6.0000000000000000
(1 row)

of course, "from foo" can be replaced by "from (... any complicated logic here ...) as foo"

Now, should the NULL row in the table be counted as 0? Then coalesce has to be used inside the avg call.

$ select coalesce(avg(coalesce(bar, 0)), 0) from foo;
      coalesce      
--------------------
 4.0000000000000000
(1 row)

For a file:

if exist yourfilename (
  echo Yes 
) else (
  echo No
)

Replace yourfilename with the name of your file.

For a directory:

if exist yourfoldername\ (
  echo Yes 
) else (
  echo No
)

Replace yourfoldername with the name of your folder.

A trailing backslash (\) seems to be enough to distinguish between directories and ordinary files.

I got this in Github desk top after clicking "Update from..." when the wrong repo was selected. I then changed repo to the correct one but when I tried to remove changes I got this error. That's because these were new files in the repo I errantly selected but not in the one I wanted to update from.

I simply changed the repo selector back to the one I incorrectly selected the first time then I was able to remove the changes.

Then I changed the repo selector to the one I wanted.

System.Text.Encoding.ChooseYourEncoding.GetString(bytes).ToCharArray();

Substitute the right encoding above: e.g.

System.Text.Encoding.UTF8.GetString(bytes).ToCharArray();

Change the rule on your <a> element from:

.navigation ul a {
    color: #000;
    display: block;
    padding: 0 65px 0 0;
    text-decoration: none;
}?

to

.navigation ul a {
    color: #000;
    display: block;
    padding: 0 65px 0 0;
    text-decoration: none;
    width:100%;
    text-align:center;
}?

Just add two new rules (width:100%; and text-align:center;). You need to make the anchor expand to take up the full width of the list item and then text-align center it.

jsFiddle example

easiest by far is to return nil, or "" in func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? for a section where you do not wish to display header.

Maybe not as elegant as some previous answers, but if you want to achieve switch cases with few large ranges, just combine ranges to a single case beforehand:

// make a switch variable so as not to change the original value
int switchVariable = variable;

//combine range 1-100 to one single case in switch
if(1 <= variable && variable <=100)
    switchVariable = 1;
switch (switchVariable) 
{ 
    case 0:
        break; 
    case 1:
        // range 1-100
        doSomething(); 
        break;
    case 101: 
        doSomethingElse(); 
        break;
    etc.
} 

I would try setting it to max-width:50px;

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

1- You are using android.graphics.Bitmap which doesn't implements Serializable class so you have to remove that class then it will work.

2- for brief you can visit how to pass data between intents.

Call cmd at the end of the batch file.

Put that code in a function (the code that can't be executed on the same thread as the GUI), and to trigger that code's execution put the following.

Thread myThread= new Thread(nameOfFunction);

workerThread.Start();

Calling the start function on the thread object will cause the execution of your function call in a new thread.

I tried to implement the result of Nick which is:

$('.selectorUsedToCreateTheDialog').dialog('option', 'title', 'My New title');

But that didn't work for me because i had multiple dialogs on 1 page. In such a situation it will only set the title correct the first time. Trying to staple commands did not work:

    $("#modal_popup").html(data);
    $("#modal_popup").dialog('option', 'title', 'My New Title');
    $("#modal_popup").dialog({ width: 950, height: 550);

I fixed this by adding the title to the javascript function arguments of each dialog on the page:

function show_popup1() {
    $("#modal_popup").html(data);
    $("#modal_popup").dialog({ width: 950, height: 550, title: 'Popup Title of my First Dialog'});
}

function show_popup2() {
    $("#modal_popup").html(data);
    $("#modal_popup").dialog({ width: 950, height: 550, title: 'Popup Title of my Other Dialog'});
}

Warning: You can only compil/debug under "Any CPU" to access to 32bits Apps...

Static classes in languages like C# exist because there are no other top-level constructs to group data and functions. In JavaScript, however, they do and so it is much more natural to just declare an object like you did. To more closely mimick the class syntax, you can declare methods like so:

const myStaticClass = {
    property: 10,

    method() {

    }
}

You use uninstall the app and change the sharedPreferences name then run this application. I think it will resolve the issue.

A sample code to retrieve values from sharedPreferences you can use the following set of code,

SharedPreferences shared = getSharedPreferences(PREF_NAME, MODE_PRIVATE);
String channel = (shared.getString(keyValue, ""));

Add to VM options: -Dspring.profiles.active=dev

Or you can add it to the build.gradle file to make it work: bootRun.systemProperties = System.properties.

You should use npm run-script build or npm build <project_folder>. More info here: https://docs.npmjs.com/cli/build.

You can embed all dlls in you main dll. See: Embedding DLLs in a compiled executable

Another way to convert an Enum-Type to an int:

enum E
{
    A = 1,   /* index 0 */
    B = 2,   /* index 1 */
    C = 4,   /* index 2 */
    D = 4    /* index 3, duplicate use of 4 */
}

void Main()
{
    E e = E.C;
    int index = Array.IndexOf(Enum.GetValues(e.GetType()), e);
    // index is 2

    E f = (E)(Enum.GetValues(e.GetType())).GetValue(index);
    // f is  E.C
}

More complex but independent from the INT values assigned to the enum values.

Extract numbers from any string at beginning position.

x <- gregexpr("^[0-9]+", years)  # Numbers with any number of digits
x2 <- as.numeric(unlist(regmatches(years, x)))

Extract numbers from any string INDEPENDENT of position.

x <- gregexpr("[0-9]+", years)  # Numbers with any number of digits
x2 <- as.numeric(unlist(regmatches(years, x)))

It turns out you can do this, with the help of the built-in Zip File System provider. However, passing a resource URI directly to Paths.get won't work; instead, one must first create a zip filesystem for the jar URI without the entry name, then refer to the entry in that filesystem:

static Path resourceToPath(URL resource)
throws IOException,
       URISyntaxException {

    Objects.requireNonNull(resource, "Resource URL cannot be null");
    URI uri = resource.toURI();

    String scheme = uri.getScheme();
    if (scheme.equals("file")) {
        return Paths.get(uri);
    }

    if (!scheme.equals("jar")) {
        throw new IllegalArgumentException("Cannot convert to Path: " + uri);
    }

    String s = uri.toString();
    int separator = s.indexOf("!/");
    String entryName = s.substring(separator + 2);
    URI fileURI = URI.create(s.substring(0, separator));

    FileSystem fs = FileSystems.newFileSystem(fileURI,
        Collections.<String, Object>emptyMap());
    return fs.getPath(entryName);
}

Update:

It’s been rightly pointed out that the above code contains a resource leak, since the code opens a new FileSystem object but never closes it. The best approach is to pass a Consumer-like worker object, much like how Holger’s answer does it. Open the ZipFS FileSystem just long enough for the worker to do whatever it needs to do with the Path (as long as the worker doesn’t try to store the Path object for later use), then close the FileSystem.

Your reference image looks like a button. Try (can also be done in Interface Builder):

UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(50, 50, 100, 44)];
[button setImage:[UIImage imageNamed:@"img"] forState:UIControlStateNormal];
[button setImageEdgeInsets:UIEdgeInsetsMake(0, -30, 0, 0)];
[button setTitle:@"Abc" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button setBackgroundColor:[UIColor yellowColor]];
[view addSubview:button];

If we want only first 5 characters from any field, then this can be achieved by Left Attribute

Vessel = f.Vessel !=null ? f.Vessel.Left(5) : ""

One thing that happened for me is that the version of R provided by my linux distribution (R version 3.0.2 provided by Ubuntu 14.04) was too old for the latest version of the package available on CRAN (in my case, plyr version 1.8.3 as of today). The solution was to use the packaging system of my distribution instead of trying to install from R (apt-get install r-cran-plyr got me version 1.8.1 of plyr). Maybe I could have tried to update R using updateR(), but I'm afraid that doing so would interfere with my distribution's package manager.

Edit (04/08/2020): I recently had an issue with a package (XML) reportedly not available for my R version (3.6.3, latest supported on Debian stretch), after an update of the package in CRAN. It was very unexpected because I already had installed it with success before (on the same version of R and same OS).

For some reason, the package was still there, but install.packages was only looking at the updated (and incompatible) version. The solution was to find the URL of the compatible version and force install.packages to use it, as follows:

install.packages("https://cran.r-project.org/src/contrib/Archive/XML/XML_3.99-0.3.tar.gz", repos=NULL, type="source", ask=FALSE)

In my experience the pythonw.exe is faster at least with using pygame.

This is an option:

dbContext.Entry(entity).State = EntityState.Detached;

First install express and http-proxy-middleware

npm install express http-proxy-middleware --save

Then in your server.js

const express = require('express');
const proxy = require('http-proxy-middleware');

const app = express();
app.use(express.static('client'));

// Add middleware for http proxying 
const apiProxy = proxy('/api', { target: 'http://localhost:8080' });
app.use('/api', apiProxy);

// Render your site
const renderIndex = (req, res) => {
  res.sendFile(path.resolve(__dirname, 'client/index.html'));
}
app.get('/*', renderIndex);

app.listen(3000, () => {
  console.log('Listening on: http://localhost:3000');
});

In this example we serve the site on port 3000, but when a request end with /api we redirect it to localhost:8080.

http://localhost:3000/api/login redirect to http://localhost:8080/api/login

Seems there's a typo (missing colon) in the JSON dict provided by jro.

The correct syntax would be:

jdata = json.load('{"uri": "http:", "foo": "bar"}')

This cleared it up for me when playing with the code.

My answer below doesn't solve the question but it relates to.

If someone is using enum instead of a class model, like this example:

public enum Counter
{
    [Display(Name = "Number 1")]
    No1 = 1,
    [Display(Name = "Number 2")]
    No2 = 2,
    [Display(Name = "Number 3")]
    No3 = 3
}

And a property to get the value when submiting:

public int No { get; set; }

In the razor page, you can use Html.GetEnumSelectList<Counter>() to get the enum properties.

<select asp-for="No" asp-items="@Html.GetEnumSelectList<Counter>()"></select>

It generates the following HTML:

<select id="No" name="No">
    <option value="1">Number 1</option>
    <option value="2">Number 2</option>
    <option value="3">Number 3</option>
</select>

Many of Microsoft's secure functions, including fopen_s(), are part of C11, so they should be portable now. You should realize that the secure functions differ in exception behaviors and sometimes in return values. Additionally you need to be aware that while these functions are standardized, it's an optional part of the standard (Annex K) that at least glibc (default on Linux) and FreeBSD's libc don't implement.

However, I fought this problem for a few years. I posted a larger set of conversion macros here., For your immediate problem, put the following code in an include file, and include it in your source code:

#pragma once
#if !defined(FCN_S_MACROS_H)
   #define   FCN_S_MACROS_H

   #include <cstdio>
   #include <string> // Need this for _stricmp
   using namespace std;

   // _MSC_VER = 1400 is MSVC 2005. _MSC_VER = 1600 (MSVC 2010) was the current
   // value when I wrote (some of) these macros.

   #if (defined(_MSC_VER) && (_MSC_VER >= 1400) )

      inline extern
      FILE*   fcnSMacro_fopen_s(char *fname, char *mode)
      {  FILE *fptr;
         fopen_s(&fptr, fname, mode);
         return fptr;
      }
      #define fopen(fname, mode)            fcnSMacro_fopen_s((fname), (mode))

   #else
      #define fopen_s(fp, fmt, mode)        *(fp)=fopen( (fmt), (mode))

   #endif //_MSC_VER

#endif // FCN_S_MACROS_H

Of course this approach does not implement the expected exception behavior.

i was search for the answer in swift 3 and this question was showed as first result in search and i get inspired the answer from it so here is the swift 3 code

let array: [String] = nsMutableArrayObject.copy() as! [String]

• Use the background-image CSS property on the <a> tag
• Set display:block and adjust width and height in CSS

This should do the trick.

Yes you are right. There is no built in mechanism for automatically updation of Android Studio. You have to manually download it and configure it.

Main build.gradle - /build.gradle

buildscript {
    ...
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1' 
        // Versions: http://jcenter.bintray.com/com/android/tools/build/gradle/
    }
    ...
}

Module specific build.gradle - /app/build.gradle

The following program calculates nCr in an efficient manner (compared to calculating factorials etc.)

import operator as op
from functools import reduce

def ncr(n, r):
    r = min(r, n-r)
    numer = reduce(op.mul, range(n, n-r, -1), 1)
    denom = reduce(op.mul, range(1, r+1), 1)
    return numer // denom  # or / in Python 2

As of Python 3.8, binomial coefficients are available in the standard library as math.comb:

>>> from math import comb
>>> comb(10,3)
120

Create a UIImageView and add UIImage to it:

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image Name"]] ;

Then add it to your view:

[self.view addSubView: imageView];

The order of a dictionary doesn't have any relationship to the order it was defined in. This is true of all dictionaries, not just those turned into JSON.

>>> {"b": 1, "a": 2}
{'a': 2, 'b': 1}

Indeed, the dictionary was turned "upside down" before it even reached json.dumps:

>>> {"id":1,"name":"David","timezone":3}
{'timezone': 3, 'id': 1, 'name': 'David'}

1. Create a new Text document and copy-paste the above code and save it as log4j2.xml.

2. Now copy this log4j2.xml file and paste it under your src folder of your Java project.

3. Run your java program again, you will see error is gone.

You can avoid the if statement if you pad it out to the length you want to limit it to.

string name1 = "Christopher";
string name2 = "Jay";
int maxLength = 5;

name1 = name1.PadRight(maxLength).Substring(0, maxLength);
name2 = name2.PadRight(maxLength).Substring(0, maxLength);

name1 will have Chris

name2 will have Jay

No if statement needed to check the length before you use substring

:not selector:

You have to do two things:

• be sure to have imported right appcompat-v7 library in your project structure -> dependencies
• change the theme in the preview window to not an AppCompat theme. Try with Holo.light or Holo.dark for example.

Unless you need more than just the contents of the file, you could use file_get_contents.

$xml = file_get_contents("http://www.example.com/file.xml");

For anything more complex, I'd use cURL.

(Update September 2012):

MRT points out in the comments that "Eclipse Version" question references a .eclipseproduct in the main folder, and it contains:

name=Eclipse Platform
id=org.eclipse.platform
version=3.x.0

So that seems more straightforward than my original answer below.

Also, Neeme Praks mentions below that there is a eclipse/configuration/config.ini which includes a line like:

eclipse.buildId=4.4.1.M20140925-0400

Again easier to find, as those are Java properties set and found with System.getProperty("eclipse.buildId").

Original answer (April 2009)

For Eclipse Helios 3.6, you can deduce the Eclipse Platform version directly from the About screen:
It is a combination of the Eclipse global version and the build Id:

Here is an example for Eclipse 3.6M6:
The version would be: 3.6.0.v201003121448, after the version 3.6.0 and the build Id I20100312-1448 (an Integration build from March 12th, 2010 at 14h48

To see it more easily, click on "Plugin Details" and sort by Version.

Note: Eclipse3.6 has a brand new cool logo:

And you can see the build Id now being displayed during the loading step of the different plugin.

All that metadata is held in the DB2 catalog tables in the SYSIBM 'schema'. It varies for the DB2/z mainframe product and the DB2/LUW distributed product but they're coming closer and closer with each release.

IBM conveniently place all their manuals up on the publib site for the world to access. My area of expertise, DB2/z, has the pages you want here.

There are a number of tables there that you'll need to reference:

SYSTABLES        for table information.
SYSINDEXES    \
SYSINDEXPART   + for index information.
SYSKEYS       /
SYSCOLUMNS       for column information.

The list of all information centers is here which should point you to the DB2/LUW version if that's your area of interest.

//works for ASCII -- no clear advantage over what is already posted...

std::string toupper(const std::string & s)
{
    std::string ret(s.size(), char());
    for(unsigned int i = 0; i < s.size(); ++i)
        ret[i] = (s[i] <= 'z' && s[i] >= 'a') ? s[i]-('a'-'A') : s[i];
    return ret;
}

Using DevTools in the latest Chrome (v29) I find these two tips very helpful for debugging events:

1. Listing jQuery events of the last selected DOM element

   • Inspect an element on the page
   • type the following in the console:

     $._data($0, "events") //assuming jQuery 1.7+

   • It will list all jQuery event objects associated with it, expand the interested event, right-click on the function of the "handler" property and choose "Show function definition". It will open the file containing the specified function.

2. Utilizing the monitorEvents() command

PostgreSQL drivers jars are included in Central Repository of Maven:

• List of included versions of PostgreSQL drivers.

For PostgreSQL up to 9.1, use:

<dependency>
    <groupId>postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>VERSION</version>
</dependency>

or for 9.2+

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>VERSION</version>
</dependency>

(Thanks to @Caspar for the correction)

I hope the following sequence of code will help you:

Bitmap targetBitmap = Bitmap.createBitmap(targetWidth, targetHeight, config);
Canvas canvas = new Canvas(targetBitmap);
Matrix matrix = new Matrix();
matrix.setRotate(mRotation,source.getWidth()/2,source.getHeight()/2);
canvas.drawBitmap(source, matrix, new Paint());

If you check the following method from ~frameworks\base\graphics\java\android\graphics\Bitmap.java

public static Bitmap createBitmap(Bitmap source, int x, int y, int width, int height,
        Matrix m, boolean filter)

this would explain what it does with rotation and translate.

You can use BigInteger:

From Integers:

byte[] array = BigInteger.valueOf(0xAABBCCDD).toByteArray();
System.out.println(Arrays.toString(array))
// --> {-86, -69, -52, -35 }

The returned array is of the size that is needed to represent the number, so it could be of size 1, to represent 1 for example. However, the size cannot be more than four bytes if an int is passed.

From Strings:

BigInteger v = new BigInteger("AABBCCDD", 16);
byte[] array = v.toByteArray();

However, you will need to watch out, if the first byte is higher 0x7F (as is in this case), where BigInteger would insert a 0x00 byte to the beginning of the array. This is needed to distinguish between positive and negative values.

1. You need to add the L character to the end of the number to make Java recognize it as a long.

   long i = 12345678910L;
   

2. Yes.

See Primitive Data Types which says "An integer literal is of type long if it ends with the letter L or l; otherwise it is of type int."

The property you need is location.hash. For example:

location.hash = 'top'; //would jump to named anchor "top

I don't know how to do the nice scroll animation without the use of dojo or some toolkit like that, but if you just need it to jump to an anchor, location.hash should do it.

(tested on FF3 and Safari 3.1.2)

You have it covered aside from using the wrong property. The scrollbar can be triggered with any property overflow, overflow-x, or overflow-y and each can be set to any of visible, hidden, scroll, auto, or inherit. You are currently looking at these two:

• auto - This value will look at the width and height of the box. If they are defined, it won't let the box expand past those boundaries. Instead (if the content exceeds those boundaries), it will create a scrollbar for either boundary (or both) that exceeds its length.

• scroll - This values forces a scrollbar, no matter what, even if the content does not exceed the boundary set. If the content doesn't need to be scrolled, the bar will appear as "disabled" or non-interactive.

If you always want the vertical scrollbar to appear:

You should use overflow-y: scroll. This forces a scrollbar to appear for the vertical axis whether or not it is needed. If you can't actually scroll the context, it will appear as a"disabled" scrollbar.

If you only want a scrollbar to appear if you can scroll the box:

Just use overflow: auto. Since your content by default just breaks to the next line when it cannot fit on the current line, a horizontal scrollbar won't be created (unless it's on an element that has word-wrapping disabled). For the vertical bar,it will allow the content to expand up to the height you have specified. If it exceeds that height, it will show a vertical scrollbar to view the rest of the content, but will not show a scrollbar if it does not exceed the height.

STEP 1.

Make sure both your adb host computer and Android device are on the same Wifi network.

STEP 2.

Connect the Android device with the computer using your USB cable. As soon as you do that, your host computer will detect your device and adb will start running in the USB mode on the computer. You can check the attached devices with adb devices whereas ensure that adb is running in the USB mode by executing adb usb.

$ adb usb
restarting in USB mode
$ adb devices
List of devices attached
ZX1D63HX9R  device

STEP 3.

Restart adb in tcpip mode with this command:

$ adb tcpip 5556
restarting in TCP mode port: 5556

STEP 4.

Find out the IP address of the Android device. There are several ways to do that:

• WAY: 1 Go to Settings -> About phone/tablet -> Status -> IP address.
• WAY: 2 Go to the list of Wi-fi networks available. The one to which you’re connected, tap on that and get to know your IP.
• WAY: 3 Try $ adb shell netcfg.

Now that you know the IP address of your device, connect your adb host to it.

$ adb connect 192.168.0.102:5556
already connected to 192.168.0.102:5556
$ adb devices
List of devices attached
ZX1D63HX9R  device
192.168.0.102:5556  device

STEP 5.

Remove the USB cable and you should be connected to your device. If you don’t see it in adb devices then just reconnect using the previous step’s command:

$ adb connect 192.168.0.102:5556
connected to 192.168.0.102:5556
$ adb devices
List of devices attached
192.168.0.102:5556  device

Either you’re good to go now or you’ll need to kill your adb server by executing adb kill-server and go through all the steps again once more.

Hope that helps!

Here's what i have tried for Eric's bonus exercise. I try to unwind of my recursive loops and return as soon as I find a subtree to be not balanced.

int heightBalanced(node *root){
    int i = 1;
    heightBalancedRecursive(root, &i);
    return i; 
} 

int heightBalancedRecursive(node *root, int *i){

    int lb = 0, rb = 0;

    if(!root || ! *i)  // if node is null or a subtree is not height balanced
           return 0;  

    lb = heightBalancedRecursive(root -> left,i);

    if (!*i)         // subtree is not balanced. Skip traversing the tree anymore
        return 0;

    rb = heightBalancedRecursive(root -> right,i)

    if (abs(lb - rb) > 1)  // not balanced. Make i zero.
        *i = 0;

    return ( lb > rb ? lb +1 : rb + 1); // return the current height of the subtree
}

Starting from CSS Selectors 4 using multiple arguments in the :not selector becomes possible (see here).

In CSS3, the :not selector only allows 1 selector as an argument. In level 4 selectors, it can take a selector list as an argument.

Example:

/* In this example, all p elements will be red, except for 
   the first child and the ones with the class special. */

p:not(:first-child, .special) {
  color: red;
}

Unfortunately, browser support is limited. For now, it only works in Safari.

...allow use of an ORDER BY in a view definition.

That's not a good idea. A view should never have an ORDER BY defined.

An ORDER BY has an impact on performance - using it a view means that the ORDER BY will turn up in the explain plan. If you have a query where the view is joined to anything in the immediate query, or referenced in an inline view (CTE/subquery factoring) - the ORDER BY is always run prior to the final ORDER BY (assuming it was defined). There's no benefit to ordering rows that aren't the final result set when the query isn't using TOP (or LIMIT for MySQL/Postgres).

Consider:

CREATE VIEW my_view AS
    SELECT i.item_id,
           i.item_description,
           it.item_type_description
      FROM ITEMS i
      JOIN ITEM_TYPES it ON it.item_type_id = i.item_type_id
  ORDER BY i.item_description

...

  SELECT t.item_id,
         t.item_description,
         t.item_type_description
    FROM my_view t
ORDER BY t.item_type_description

...is the equivalent to using:

  SELECT t.item_id,
         t.item_description,
         t.item_type_description
    FROM (SELECT i.item_id,
                 i.item_description,
                 it.item_type_description
            FROM ITEMS i
            JOIN ITEM_TYPES it ON it.item_type_id = i.item_type_id
        ORDER BY i.item_description) t
ORDER BY t.item_type_description

This is bad because:

1. The example is ordering the list initially by the item description, and then it's reordered based on the item type description. It's wasted resources in the first sort - running as is does not mean it's running: ORDER BY item_type_description, item_description
2. It's not obvious what the view is ordered by due to encapsulation. This does not mean you should create multiple views with different sort orders...

If you are using CentOS linux system the Maven local repositary will be:

/root/.m2/repository/

You can remove .m2 and build your maven project in dev tool will fix the issue.

You can't increase the array's length if it is not declared in heap memory (see below code which first array input is asked by user and then it asks how much you want to increase array and also copy previous array elements):

#include<stdio.h>
#include<stdlib.h>

int * increasesize(int * p,int * q,int x)
{
    int i;
    for(i=0;i<x;i++)
    {
         q[i]=p[i];
    }
    free(p);
    p=q;
    return p;
}
void display(int * q,int x)
{
    int i;
    for(i=0;i<x;i++)
    {
        printf("%d \n",q[i]);
        
    }
}

int main()
{
    int x,i;
    printf("enter no of element to create array");
    scanf("%d",&x);
    int * p=(int *)malloc(x*sizeof(int));
    printf("\n enter number in the array\n");
    for(i=0;i<x;i++)
    {
        scanf("%d",&p[i]);
    }
    int y;
    printf("\nenter the new size to create new size of array");
    scanf("%d",&y);
    int * q=(int *)malloc(y*sizeof(int));
    display(increasesize(p,q,x),y);
    free(q);
}

$start_date = new DateTime();
$start_date->setTimestamp($dbResult->db_timestamp);

You can have return in a void method, you just can't return any value (as in return 5;), that's why they call it a void method. Some people always explicitly end void methods with a return statement, but it's not mandatory. It can be used to leave a function early, though:

void someFunct(int arg)
{
    if (arg == 0)
    {
        //Leave because this is a bad value
        return;
    }
    //Otherwise, do something
}

You could use RegEx:

Regex.IsMatch(hello, @"^[a-zA-Z]+$");

If you don't like that, you can use LINQ:

hello.All(Char.IsLetter);

Or, you can loop through the characters, and use isAlpha:

Char.IsLetter(character);

In addition at the Daniel Vassallo solution, if you use SQL Server 2016+, there is another solution that I used in some cases without considerable lost of performances.

You can create just a table with only the common field and add a single column with the JSON string that contains all the subtype specific fields.

I have tested this design for manage inheritance and I am very happy for the flexibility that I can use in the relative application.

Recursion can be hard to grasp sometimes. Just evaluate it on a piece of paper for a small number:

fib(4)
-> fib(3) + fib(2)
-> fib(2) + fib(1) + fib(1) + fib(0)
-> fib(1) + fib(0) + fib(1) + fib(1) + fib(0)
-> 1 + 0 + 1 + 1 + 0
-> 3

I am not sure how Java actually evaluates this, but the result will be the same.

Xml declaration is optional so your xml is well-formed without it. But it is recommended to use it so that wrong assumptions are not made by the parsers, specifically about the encoding used.

Try this

SELECT Count(*) AS N
FROM
(SELECT DISTINCT Name FROM table1) AS T;

Angular 2 provides good support for uploading files. No third party library is required.

<input type="file" (change)="fileChange($event)" placeholder="Upload file" accept=".pdf,.doc,.docx">

fileChange(event) {
    let fileList: FileList = event.target.files;
    if(fileList.length > 0) {
        let file: File = fileList[0];
        let formData:FormData = new FormData();
        formData.append('uploadFile', file, file.name);
        let headers = new Headers();
        /** In Angular 5, including the header Content-Type can invalidate your request */
        headers.append('Content-Type', 'multipart/form-data');
        headers.append('Accept', 'application/json');
        let options = new RequestOptions({ headers: headers });
        this.http.post(`${this.apiEndPoint}`, formData, options)
            .map(res => res.json())
            .catch(error => Observable.throw(error))
            .subscribe(
                data => console.log('success'),
                error => console.log(error)
            )
    }
}

A more modern solution that utilises the URL WebAPI:

(req, res) => {
  const { pathname } = new URL(req.url || '', `https://${req.headers.host}`)
}

A file can be tracked or not, you use hg add to track a file and hg remove or hg forget to un-track it. Using hg remove without flags will both delete the file and un-track it, hg forget will simply un-track it without deleting it.

Try this:

$categories     =   Category::all()->sortByDesc("created_at");

Library Seaborn has this built in with function .despine().

Just add:

import seaborn as sns

Now create your graph. And add at the end:

sns.despine()

If you look at some of the default parameter values of the function it removes the top and right spine and keeps the bottom and left spine:

sns.despine(top=True, right=True, left=False, bottom=False)

Check out further documentation here: https://seaborn.pydata.org/generated/seaborn.despine.html

Angular 2.0.0 Final:

I have found that using a ViewChild setter is most reliable way to set the initial form control focus:

@ViewChild("myInput")
set myInput(_input: ElementRef | undefined) {
    if (_input !== undefined) {
        setTimeout(() => {
            this._renderer.invokeElementMethod(_input.nativeElement, "focus");
        }, 0);
    }
}

The setter is first called with an undefined value followed by a call with an initialized ElementRef.

Working example and full source here: http://plnkr.co/edit/u0sLLi?p=preview

Using TypeScript 2.0.3 Final/RTM, Angular 2.0.0 Final/RTM, and Chrome 53.0.2785.116 m (64-bit).

UPDATE for Angular 4+

Renderer has been deprecated in favor of Renderer2, but Renderer2 does not have the invokeElementMethod. You will need to access the DOM directly to set the focus as in input.nativeElement.focus().

I'm still finding that the ViewChild setter approach works best. When using AfterViewInit I sometimes get read property 'nativeElement' of undefined error.

@ViewChild("myInput")
set myInput(_input: ElementRef | undefined) {
    if (_input !== undefined) {
        setTimeout(() => { //This setTimeout call may not be necessary anymore.
            _input.nativeElement.focus();
        }, 0);
    }
}

As Danack said in comments, there are 2 php.ini files. I uncommented the line with curl extension in the one in Apache folder, which is php.ini used by the web server.

Composer, on the other hand, uses php for console which is a whole different story. Php.ini file for that program is not the one in Apache folder but it's in the PHP folder and I had to uncomment the line in it too. Then I ran the installation again and it was OK.

This works for me

1. Open the file in BBEdit or TextWrangler*.
2. Set the file as Unicode (UTF-16 Little-Endian) (Line Endings can be Unix or Windows). Save!
3. In Excel: Data > Get External Data > Import Text File...

Now the key point, choose MacIntosh as File Origin (it should be the first choice).

This is using Excel 2011 (version 14.4.2)

*There's a little dropdown at the bottom of the window

Invoke mysql with the -N (the alias for -N is --skip-column-names) option:

mysql -N ...
use testdb;
select * from names;

+------+-------+
|    1 | pete  |
|    2 | john  |
|    3 | mike  |
+------+-------+
3 rows in set (0.00 sec)

Credit to ErichBSchulz for pointing out the -N alias.

To remove the grid (the vertical and horizontal lines) around the results use -s (--silent). Columns are separated with a TAB character.

mysql -s ...
use testdb;
select * from names;

id  name
1   pete
2   john
3   mike

To output the data with no headers and no grid just use both -s and -N.

mysql -sN ...

The file: URL scheme refers to a file on the client machine. There is no hostname in the file: scheme; you just provide the path of the file. So, the file on your local machine would be file:///~User/2ndFile.html. Notice the three slashes; the hostname part of the URL is empty, so the slash at the beginning of the path immediately follows the double slash at the beginning of the URL. You will also need to expand the user's path; ~ does no expand in a file: URL. So you would need file:///home/User/2ndFile.html (on most Unixes), file:///Users/User/2ndFile.html (on Mac OS X), or file:///C:/Users/User/2ndFile.html (on Windows).

Many browsers, for security reasons, do not allow linking from a file that is loaded from a server to a local file. So, you may not be able to do this from a page loaded via HTTP; you may only be able to link to file: URLs from other local pages.

for Python in Windows:

python -m pip uninstall "package_keyword"
uninstall **** (y/n)?

If you want to use requirements.txt file, you will need git and something like the entry below to anonymously fetch the master branch in your requirements.txt.

For regular install:

git+git://github.com/celery/django-celery.git

For "editable" install:

-e git://github.com/celery/django-celery.git#egg=django-celery

Editable mode downloads the project's source code into ./src in the current directory. It allows pip freeze to output the correct github location of the package.

@echo off
C:
SET mypath=%~dp0
c:\cygwin\bin\bash -c "cd '%mypath%'; export CHERE_INVOKING=1; exec /bin/bash --login -i"

Copy above commands in a text file and save it as .bat in any of "your folder of interest". It should open cygwin in "your folder of interest".

You have not defined the variable input_line.

Add this:

string input_line;

And add this include.

#include <string>

Here is the full example. I also removed the semi-colon after the while loop, and you should have getline inside the while to properly detect the end of the stream.

#include <iostream>
#include <string>

int main() {
    for (std::string line; std::getline(std::cin, line);) {
        std::cout << line << std::endl;
    }
    return 0;
}

Try this:

@keyframes animationName {
  0%   { opacity:0; }
  50%  { opacity:1; }
  100% { opacity:0; }
}
@-o-keyframes animationName{
  0%   { opacity:0; }
  50%  { opacity:1; }
  100% { opacity:0; }
}
@-moz-keyframes animationName{
  0%   { opacity:0; }
  50%  { opacity:1; }
  100% { opacity:0; }
}
@-webkit-keyframes animationName{
  0%   { opacity:0; }
  50%  { opacity:1; }
  100% { opacity:0; }
}   
.elementToFadeInAndOut {
   -webkit-animation: animationName 5s infinite;
   -moz-animation: animationName 5s infinite;
   -o-animation: animationName 5s infinite;
    animation: animationName 5s infinite;
}

SELECT cast( cast(round(37.0/38.0,2) AS DECIMAL(18,2)) as varchar(100)) + ' %'

RESULT:  0.97 %

You can try specifying a width for the div, whether it be in pixels, percentages or ems, and at that point the div will remain that width and the text will wrap automatically then within the div.

DANGER AHEAD: (please read the comments. Executing the command proposed in my answer might delete more than you want)

to completely remove all files including directories I had to run

git clean -f -d

Make sure that if you have nvarchar(50)in DB row you don't trying to insert more than 50characters in it. Stupid mistake but took me 3 hours to figure it out.

There is a built-in method to get the bounding rectangle: Element.getBoundingClientRect.

The result is the smallest rectangle which contains the entire element, with the read-only left, top, right, bottom, x, y, width, and height properties.

See the example below:

let innerBox = document.getElementById("myDiv").getBoundingClientRect().height;_x000D_
document.getElementById("data_box").innerHTML = "height: " + innerBox;

body {_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.relative {_x000D_

It's something like this, for a dotnet 2.x core console application:

        using Microsoft.Extensions.Configuration;
        using Microsoft.Extensions.DependencyInjection;
        using Microsoft.Extensions.Logging;

        [...]
        var configuration = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
            .AddEnvironmentVariables()
            .Build();
        var serviceProvider = new ServiceCollection()
            .AddLogging(options => options.AddConfiguration(configuration).AddConsole())
            .AddSingleton<IConfiguration>(configuration)
            .AddSingleton<SomeService>()
            .BuildServiceProvider();
        [...]
        await serviceProvider.GetService<SomeService>().Start();

The you could inject ILoggerFactory, IConfiguration in the SomeService.

You should investigate why VBA can't find queryname.

I have a saved query named qryAddLoginfoRow. It inserts a row with the current time into my loginfo table. That query runs successfully when called by name by CurrentDb.Execute.

CurrentDb.Execute "qryAddLoginfoRow"

My guess is that either queryname is a variable holding the name of a query which doesn't exist in the current database's QueryDefs collection, or queryname is the literal name of an existing query but you didn't enclose it in quotes.

Edit: You need to find a way to accept that queryname does not exist in the current db's QueryDefs collection. Add these 2 lines to your VBA code just before the CurrentDb.Execute line.

Debug.Print "queryname = '" & queryname & "'"
Debug.Print CurrentDb.QueryDefs(queryname).Name

The second of those 2 lines will trigger run-time error 3265, "Item not found in this collection." Then go to the Immediate window to verify the name of the query you're asking CurrentDb to Execute.

Haven't seen this solution yet so here's how I did it without using read_csv:

df.rename(columns={'A':'','B':''})

If you rename all your column names to empty strings your table will return without a header.

And if you have a lot of columns in your table you can just create a dictionary first instead of renaming manually:

df_dict = dict.fromkeys(df.columns, '')
df.rename(columns = df_dict)

The docker documentation (and self-explanation) makes a distinction between "virtual machines" vs. "containers". They have the tendency to interpret and use things in a little bit uncommon ways. They can do that because it is up to them, what do they write in their documentation, and because the terminology for virtualization is not yet really exact.

Fact is what the Docker documentation understands on "containers", is paravirtualization (sometimes "OS-Level virtualization") in the reality, contrarily the hardware virtualization, which is docker not.

Docker is a low quality paravirtualisation solution. The container vs. VM distinction is invented by the docker development, to explain the serious disadvantages of their product.

The reason, why it became so popular, is that they "gave the fire to the ordinary people", i.e. it made possible the simple usage of typically server ( = Linux) environments / software products on Win10 workstations. This is also a reason for us to tolerate their little "nuance". But it does not mean that we should also believe it.

The situation is made yet more cloudy by the fact that docker on Windows hosts used an embedded Linux in HyperV, and its containers have run in that. Thus, docker on Windows uses a combined hardware and paravirtualization solution.

In short, Docker containers are low-quality (para)virtual machines with a huge advantage and a lot of disadvantages.

on android devices using chrome we can't detect a backspace. You can use workaround for it:

var oldInput = '',
    newInput = '';

 $("#ID").keyup(function () {
  newInput = $('#ID').val();
   if(newInput.length < oldInput.length){
      //backspace pressed
   }
   oldInput = newInput;
 })

I have been looking at the answers all impressive. I think He should provide the code that is giving him a problem. Given the example below, If you have a script to link to jquery in page.php then you get that notice.

$().ready(function () {
    $.ajax({url: "page.php",
        type: 'GET',
        success: function (result) {
        $("#page").html(result);
   }});
 });

I think Todd is correct, but I think there's one other thing you should consider. You can reliably get the home directory from the JVM at runtime, and then you can create files objects relative to that location. It's not that much more trouble, and it's something you'll appreciate if you ever move to another computer or operating system.

File homedir = new File(System.getProperty("user.home"));
File fileToRead = new File(homedir, "java/ex.txt");

You can also use an online calculator to calculate the two's complement binary representation of a decimal number: http://www.convertforfree.com/twos-complement-calculator/

I had the same error when was trying to update linked table.

The issue was that linked table had no PRIMARY KEY.

After adding primary key constraint on database side and re linking this table to access problem was solved.

Hope it will help somebody.

You can't detect the codepage, you need to be told it. You can analyse the bytes and guess it, but that can give some bizarre (sometimes amusing) results. I can't find it now, but I'm sure Notepad can be tricked into displaying English text in Chinese.

Anyway, this is what you need to read: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!).

Specifically Joel says:

The Single Most Important Fact About Encodings

If you completely forget everything I just explained, please remember one extremely important fact. It does not make sense to have a string without knowing what encoding it uses. You can no longer stick your head in the sand and pretend that "plain" text is ASCII. There Ain't No Such Thing As Plain Text.

If you have a string, in memory, in a file, or in an email message, you have to know what encoding it is in or you cannot interpret it or display it to users correctly.

Here is another option.

os.scandir(path='.')

It returns an iterator of os.DirEntry objects corresponding to the entries (along with file attribute information) in the directory given by path.

Example:

with os.scandir(path) as it:
    for entry in it:
        if not entry.name.startswith('.'):
            print(entry.name)

Using scandir() instead of listdir() can significantly increase the performance of code that also needs file type or file attribute information, because os.DirEntry objects expose this information if the operating system provides it when scanning a directory. All os.DirEntry methods may perform a system call, but is_dir() and is_file() usually only require a system call for symbolic links; os.DirEntry.stat() always requires a system call on Unix but only requires one for symbolic links on Windows.

If you use Db Browser for sqlite ,then it will be easy for you to modify the table. you can add foreign key in existing table without writing a query.

• Open your database in Db browser,
• Just right click on table and click modify,
• At there scroll to foreign key column,
• double click on field which you want to alter,
• Then select table and it's field and click ok.

that's it. You successfully added foreign key in existing table.

I guess you are asking why is 1388516401 equal to 2014-01-01...?

There is an historical reason for that. There is a 32-bit integer variable, called time_t, that keeps the count of the time elapsed since 1970-01-01 00:00:00. Its value expresses time in seconds. This means that in 2014-01-01 00:00:01 time_t will be equal to 1388516401.

This leads us for sure to another interesting fact... In 2038-01-19 03:14:07 time_t will reach 2147485547, the maximum value for a 32-bit number. Ever heard about John Titor and the Year 2038 problem? :D

I was struggling with this recently, and found the right way to create a default task that runs sass then sass:watch was:

gulp.task('default', gulp.series('sass', 'sass:watch'));

I'm suprised that no one mentioned this.

Use the Sieve Of Eratosthenes

Details:

1. Basically nonprime numbers are divisible by another number besides 1 and themselves
2. Therefore: a nonprime number will be a product of prime numbers.

The sieve of Eratosthenes finds a prime number and stores it. When a new number is checked for primeness all of the previous primes are checked against the know prime list.

Reasons:

1. This algorithm/problem is known as "Embarrassingly Parallel"
2. It creates a collection of prime numbers
3. Its an example of a dynamic programming problem
4. Its quick!

In front-end JavaScript/HTML, you can load a binary file as an image, you do not have to convert to base64:

<img src="http://engci.nabisco.com/artifactory/repo/folder/my-image">

my-image is a binary image file. This will load just fine.

You need to pass in a sequence, but you forgot the comma to make your parameters a tuple:

cursor.execute('INSERT INTO images VALUES(?)', (img,))

Without the comma, (img) is just a grouped expression, not a tuple, and thus the img string is treated as the input sequence. If that string is 74 characters long, then Python sees that as 74 separate bind values, each one character long.

>>> len(img)
74
>>> len((img,))
1

If you find it easier to read, you can also use a list literal:

cursor.execute('INSERT INTO images VALUES(?)', [img])

You can use triple quotes (single ' or double "):

a = """
text
text
text
"""

print(a)

If it's just a substring search you can use string.find("substring").

You do have to be a little careful with find, index, and in though, as they are substring searches. In other words, this:

s = "This be a string"
if s.find("is") == -1:
    print("No 'is' here!")
else:
    print("Found 'is' in the string.")

It would print Found 'is' in the string. Similarly, if "is" in s: would evaluate to True. This may or may not be what you want.

I know this is a rather old post but I have another slightly simpler solution. You could create another class within and make it abstract. Next make an Abstract method name it whatever you like. In the original class make a method that takes the new class as a parameter, in this method call the abstract method. It will look something like this.

public class Demo {

    public Demo(/.../){

    }

    public void view(Action a){
        a.preform();
    }

    /**
     * The Action Class is for making the Demo
     * View Custom Code
     */
    public abstract class Action {

        public Action(/.../){

        }

        abstract void preform();
    }
}

Now you can do something like this to call a method from within the class.

/...
Demo d = new Demo;
Action a = new Action() {

    @Override
    void preform() {
        //Custom Method Code Goes Here
    }
};

/.../
d.view(a)

Like I said I know its old but this way I think is a little easier. Hope it helps.

i have some problems with it, and fixed it my using another config variable

$cfg['Servers'][$i]['AllowNoPassword'] = true;
instead
$cfg['Servers'][$i]['AllowNoPasswordRoot'] = true;

may be it will helpfull ot someone

The behavior you're trying to produce is not really best done using AJAX. AJAX would be best used if you wanted to only update a portion of the page, not completely redirect to some other page. That defeats the whole purpose of AJAX really.

I would suggest to just not use AJAX with the behavior you're describing.

Alternatively, you could try using jquery Ajax, which would submit the request and then you specify a callback when the request completes. In the callback you could determine if it failed or succeeded, and redirect to another page on success. I've found jquery Ajax to be much easier to use, especially since I'm already using the library for other things anyway.

You can find documentation about jquery ajax here, but the syntax is as follows:

jQuery.ajax( options )  

jQuery.get( url, data, callback, type)

jQuery.getJSON( url, data, callback )

jQuery.getScript( url, callback )

jQuery.post( url, data, callback, type)

One of the values you pass on to Ancestors becomes None at some point, it says, so check if otu, tree, tree[otu] or tree[otu][0] are None in the beginning of the function instead of only checking tree[otu][0][0] == None. But perhaps you should reconsider your path of action and the datatype in question to see if you could improve the structure somewhat.

I had similar problem . Two components communicating with each other was using a queue .

First component was not doing json.dumps before putting message to queue. So the JSON string generated by receiving component was in single quotes. This was causing error

 Expecting property name enclosed in double quotes

Adding json.dumps started creating correctly formatted JSON & solved issue.

I had the same issue. I added following attributes to <xs:schema..> elementFormDefault="qualified" attributeFormDefault="unqualified"

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns="http://www.example.com/schemas/ArrayOfMarketWithStations"
    targetNamespace="http://www.example.com/schemas/ArrayOfMarketWithStations" 
    elementFormDefault="qualified" attributeFormDefault="unqualified" >

and re-generated java classes by running xjc, which corrected package-info.java.

@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.example.com/schemas/ArrayOfMarketWithStations", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)

This fixed the issue for me.

The following CSS changes in bold (plus a bunch of content in the columns to test scrolling) will work. See the result in this Pen.

.content { flex: 1; display: flex; height: 1px; }

.column { padding: 20px; border-right: 1px solid #999; overflow: auto; }

The trick seems to be that a scrollable panel needs to have a height literally set somewhere (in this case, via its parent), not just determined by flexbox. So even height: 1px works. The flex-grow:1 will still size the panel to fit properly.

You are facing issue in

 s1.name="Paolo";

because, in the LHS, you're using an array type, which is not assignable.

To elaborate, from C11, chapter §6.5.16

assignment operator shall have a modifiable lvalue as its left operand.

and, regarding the modifiable lvalue, from chapter §6.3.2.1

A modifiable lvalue is an lvalue that does not have array type, [...]

You need to use strcpy() to copy into the array.

That said, data s1 = {"Paolo", "Rossi", 19}; works fine, because this is not a direct assignment involving assignment operator. There we're using a brace-enclosed initializer list to provide the initial values of the object. That follows the law of initialization, as mentioned in chapter §6.7.9

Each brace-enclosed initializer list has an associated current object. When no designations are present, subobjects of the current object are initialized in order according to the type of the current object: array elements in increasing subscript order, structure members in declaration order, and the first named member of a union.[....]

First, give permission for execution:-
chmod +x script_name

1. If script is not executable:-
   For running sh script file:-
   sh script_name
   For running bash script file:-
   bash script_name
2. If script is executable:-
   ./script_name

NOTE:-you can check if the file is executable or not by using 'ls -a'

I think you need to use one of those methods in order to be able to intercept the event before it gets sent to the appropriate components:

Activity.dispatchTouchEvent(MotionEvent) - This allows your Activity to intercept all touch events before they are dispatched to the window.

ViewGroup.onInterceptTouchEvent(MotionEvent) - This allows a ViewGroup to watch events as they are dispatched to child Views.

ViewParent.requestDisallowInterceptTouchEvent(boolean) - Call this upon a parent View to indicate that it should not intercept touch events with onInterceptTouchEvent(MotionEvent).

More information here.

Hope that helps.

Any user with a valid shell in /etc/passwd can potentially login. If you want to improve security, set up SSH with public-key authentication (there is lots of info on the web on doing this), install a public key in one user's ~/.ssh/authorized_keys file, and disable password-based authentication. This will prevent anybody except that one user from logging in, and will require that the user have in their possession the matching private key. Make sure the private key has a decent passphrase.

To prevent bots from trying to get in, run SSH on a port other than 22 (i.e. 3456). This doesn't improve security but prevents script-kiddies and bots from cluttering up your logs with failed attempts.

For use variables in for example alter table:

DO $$ 
DECLARE name_pk VARCHAR(200);
BEGIN
select constraint_name
from information_schema.table_constraints
where table_schema = 'schema_name'
      and table_name = 'table_name'
      and constraint_type = 'PRIMARY KEY' INTO name_pk;
IF (name_pk := '') THEN
EXECUTE 'ALTER TABLE schema_name.table_name DROP CONSTRAINT ' || name_pk;

How about alias gcc99= gcc -std=c99?

So, I tested above themes and found out none of them are showing proper color combination when using Productivity Power Tools in Visual Studio.
Ultimately, being a fan of dark themes, I created one myself which is fully supported from VS2005 to VS2013.
Here's the screenshot

Download this dark theme from here: Obsidian Meets Visual Studio

To use this theme go to Tools -> Import and Export Setting... -> import selected environment settings -> (optional to save current settings) -> Browse select and then Finish.

This is such a common problem, especially in GUI applications, that I'm surprised there isn't a BCL class to do this out of the box. Here's how I do it.

public static class ReflectiveEnumerator
{
    static ReflectiveEnumerator() { }

    public static IEnumerable<T> GetEnumerableOfType<T>(params object[] constructorArgs) where T : class, IComparable<T>
    {
        List<T> objects = new List<T>();
        foreach (Type type in 
            Assembly.GetAssembly(typeof(T)).GetTypes()
            .Where(myType => myType.IsClass && !myType.IsAbstract && myType.IsSubclassOf(typeof(T))))
        {
            objects.Add((T)Activator.CreateInstance(type, constructorArgs));
        }
        objects.Sort();
        return objects;
    }
}

A few notes:

• Don't worry about the "cost" of this operation - you're only going to be doing it once (hopefully) and even then it's not as slow as you'd think.
• You need to use Assembly.GetAssembly(typeof(T)) because your base class might be in a different assembly.
• You need to use the criteria type.IsClass and !type.IsAbstract because it'll throw an exception if you try to instantiate an interface or abstract class.
• I like forcing the enumerated classes to implement IComparable so that they can be sorted.
• Your child classes must have identical constructor signatures, otherwise it'll throw an exception. This typically isn't a problem for me.

You can use BIGINT as follows:

CREATE TABLE user_reg (
user_id INT NOT NULL AUTO_INCREMENT,
identifier INT,
phone_number CHAR(11) NOT NULL,
verified TINYINT UNSIGNED NOT NULL,
reg_time BIGINT,
last_active_time BIGINT,
PRIMARY KEY (user_id),
INDEX (phone_number, user_id, identifier)
   );

Working with bootstrap panels, I was seeking how to place "delete" link in header panel, which would not be obscured by long neighbour element. And here is the solution:

html:

<div class="with-right-link">
    <a class="left-link" href="#">Long link header Long link header</a>
    <a class="right-link" href="#">Delete</a>
</div>

css:

.with-right-link { position: relative; width: 275px; }
a.left-link { display: inline-block; margin-right: 100px; }
a.right-link { position: absolute; top: 0; right: 0; }

Of course you can modify "top" and "right" values, according to your indentations. Source

As of SciPy version 1.1, you can also use find_peaks. Below are two examples taken from the documentation itself.

Using the height argument, one can select all maxima above a certain threshold (in this example, all non-negative maxima; this can be very useful if one has to deal with a noisy baseline; if you want to find minima, just multiply you input by -1):

import matplotlib.pyplot as plt
from scipy.misc import electrocardiogram
from scipy.signal import find_peaks
import numpy as np

x = electrocardiogram()[2000:4000]
peaks, _ = find_peaks(x, height=0)
plt.plot(x)
plt.plot(peaks, x[peaks], "x")
plt.plot(np.zeros_like(x), "--", color="gray")
plt.show()

Another extremely helpful argument is distance, which defines the minimum distance between two peaks:

peaks, _ = find_peaks(x, distance=150)
# difference between peaks is >= 150
print(np.diff(peaks))
# prints [186 180 177 171 177 169 167 164 158 162 172]

plt.plot(x)
plt.plot(peaks, x[peaks], "x")
plt.show()

You can also misuse File.list(FilenameFilter) (and variants) for file traversal. Short code and works in early java versions, e.g:

// list files in dir
new File(dir).list(new FilenameFilter() {
    public boolean accept(File dir, String name) {
        String file = dir.getAbsolutePath() + File.separator + name;
        System.out.println(file);
        return false;
    }
});
