You did not post the code generated by the compiler, so there' some guesswork here, but even without having seen it, one can say that this:

test rax, 1
jpe even

... has a 50% chance of mispredicting the branch, and that will come expensive.

The compiler almost certainly does both computations (which costs neglegibly more since the div/mod is quite long latency, so the multiply-add is "free") and follows up with a CMOV. Which, of course, has a zero percent chance of being mispredicted.

You miss the from clause

SELECT *  from TCCAWZTXD.TCC_COIL_DEMODATA WHERE CURRENT_INSERTTIME  BETWEEN(CURRENT_TIMESTAMP)-5 minutes AND CURRENT_TIMESTAMP

In my case the user could not connect to the database. If will have same issue if the log contains a warning just before the exception:

There's only one error:

cout.cpp:26:29: error: no match for ‘operator<<’ in ‘std::operator<< [with _Traits = std::char_traits]((* & std::cout), ((const char*)"my structure ")) << m’

This means that the compiler couldn't find a matching overload for operator<<. The rest of the output is the compiler listing operator<< overloads that didn't match. The third line actually says this:

cout.cpp:26:29: note: candidates are:

I was getting this error after adding the include files and linking the library. It was because the lib was built with non-unicode and my application was unicode. Matching them fixed it.

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

There is a vcvars32.bat in your Visual Studio installation directory. You can add call cmd.exe at the end of that batch program and launch it. From that shell you can use CMake or cmake-gui and cl.exe would be known to CMake.

You need to move the unique_ptr:

vec.push_back(std::move(ptr2x));

unique_ptr guarantees that a single unique_ptr container has ownership of the held pointer. This means that you can't make copies of a unique_ptr (because then two unique_ptrs would have ownership), so you can only move it.

Note, however, that your current use of unique_ptr is incorrect. You cannot use it to manage a pointer to a local variable. The lifetime of a local variable is managed automatically: local variables are destroyed when the block ends (e.g., when the function returns, in this case). You need to dynamically allocate the object:

std::unique_ptr<int> ptr(new int(1));

In C++14 we have an even better way to do so:

make_unique<int>(5);

I've tried a select statement now with a PreparedStatement, but it turned out that it was not faster than the Jdbc template. Maybe, as mezmo suggested, it automatically creates prepared statements.

Anyway, the reason for my sql SELECTs being so slow was another one. In the WHERE clause I always used the operator LIKE, when all I wanted to do was finding an exact match. As I've found out LIKE searches for a pattern and therefore is pretty slow.

I'm using the operator = now and it's much faster.

if the name of your list is listlen then just type len(listlen). This will return the size of your list in the python.

Technically 'Yes'

(but not really...)

HTML 5's <video> tag is protocol agnostic—it does not care. You place the protocol in the src attribute as part of the URL. E.g.:

<video src="rtp://myserver.com/path/to/stream">
    Your browser does not support the VIDEO tag and/or RTP streams.
</video>

or maybe

<video src="http://myserver.com:1935/path/to/stream/myPlaylist.m3u8">
    Your browser does not support the VIDEO tag and/or RTP streams.
</video>

That said, the implementation of the <video> tag is browser specific. Since it is early days for HTML 5, I expect frequently changing support (or lack of support).

From the W3C's HTML5 spec (The video element):

User agents may support any video and audio codecs and container formats

I did some development with Mifare Classic (ISO 14443A) cards about 7-8 years ago. You can read and write to all sectors of the card, IIRC the only data you can't change is the serial number. Back then we used a proprietary library from Philips Semiconductors. The command interface to the card was quite alike the ISO 7816-4 (used with standard Smart Cards).

I'd recomment that you look at the OpenPCD platform if you are into development.

This is also of interest regarding the cryptographic functions in some RFID cards.

Try this:

mtcars %>%
  group_by(am, gear) %>%
  summarise(n = n()) %>%
  mutate(freq = n / sum(n))

#   am gear  n      freq
# 1  0    3 15 0.7894737
# 2  0    4  4 0.2105263
# 3  1    4  8 0.6153846
# 4  1    5  5 0.3846154

From the dplyr vignette:

When you group by multiple variables, each summary peels off one level of the grouping. That makes it easy to progressively roll-up a dataset.

Thus, after the summarise, the last grouping variable specified in group_by, 'gear', is peeled off. In the mutate step, the data is grouped by the remaining grouping variable(s), here 'am'. You may check grouping in each step with groups.

The outcome of the peeling is of course dependent of the order of the grouping variables in the group_by call. You may wish to do a subsequent group_by(am), to make your code more explicit.

For rounding and prettification, please refer to the nice answer by @Tyler Rinker.

I had similar issue when connecting to RDS Oracle even when client and server were both set to TLSv1.2 the certs was right and java was 1.8.0_141 So Finally I had to apply patch at Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files

After applying the patch the issue went away and connection went fine.

Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:

Sub FilterAndCopy()
Dim LastRow As Long

Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
    .Range("$A:$E").AutoFilter
    .Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
    .Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
    .Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
    .Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
    LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    .Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
            Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub

As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.

I don't think "blueprint" is a good word to use. A blueprint tells you how to build something. An interface specifically avoids telling you how to build something.

An interface defines how you can interact with a class, i.e. what methods it supports.

May be there password is not set and you are passing password as argument. Try ommitting password argument during connection..

Others are correct in saying that setting button.enabled = false doesn't prevent the button from triggering. However, I found that setting button.visible = false does work. The button disappears and can't be clicked until you set visible to true again.

I had the same problem. For some reason --initialize did not work. After about 5 hours of trial and error with different parameters, configs and commands I found out that the problem was caused by the file system.

The "d.ts" file is used to provide typescript type information about an API that's written in JavaScript. The idea is that you're using something like jQuery or underscore, an existing javascript library. You want to consume those from your typescript code.

Rather than rewriting jquery or underscore or whatever in typescript, you can instead write the d.ts file, which contains only the type annotations. Then from your typescript code you get the typescript benefits of static type checking while still using a pure JS library.

Subtracting the Minimum of the ends of the ranges from the Maximum of the beginning seems to do the trick. If the result is less than or equal to zero, we have an overlap. This visualizes it well:

Replace

with following

include_path="C:\Program Files (x86)\xampp\php\PEAR"

I don't want to suggest a product out of turn, since getting Intellisense running is probably the best option, but I've struggled with the accursed no intellisense on Management Studio for months. Reinstallation, CU7 update, refreshing caches, sacrificing chickens to pagan gods; nothing has helped.

I was about to pay for RedGate's SqlPrompt (pretty damned pricey, $195 US), when I found SqlComplete.

http://www.devart.com/dbforge/sql/sqlcomplete/?gclid=CN2xs_Lw7akCFcYZHAodpicXXw

There is a free version which does the basics, and the full version is only $50!

I'm a database architect, and while I can remember the commands, auto complete saves me heaps of time. If you're stuck and can't get Intellisense to work, try SqlComplete. It saved me hours of hassle.

You can combine the two functions; coerce to characters thence to numerics:

I'm surprised there isn't this easy way : key.delete() :

from boto.s3.connection import S3Connection, Bucket, Key

conn = S3Connection(AWS_ACCESS_KEY, AWS_SECERET_KEY)
bucket = Bucket(conn, S3_BUCKET_NAME)
k = Key(bucket = bucket, name=path_to_file)
k.delete()

Start with:

setup.exe /?

And you should see a dialog popup with some options displayed.

If the file is coming off the disk and as others have stated, use the BaseName and Extension properties:

PS C:\> dir *.xlsx | select BaseName,Extension

BaseName                                Extension
--------                                ---------
StackOverflow.com Test Config           .xlsx  

If you are given the file name as part of string (say coming from a text file), I would use the GetFileNameWithoutExtension and GetExtension static methods from the System.IO.Path class:

PS C:\> [System.IO.Path]::GetFileNameWithoutExtension("Test Config.xlsx")
Test Config
PS H:\> [System.IO.Path]::GetExtension("Test Config.xlsx")
.xlsx

Write down this and try to import pandas again!

It worked for me, hope will work for you too.

The much longer example below combines some of the useful snippets above:

• You can specify any number of sheets you want to copy across
• You can copy entire sheets, i.e. like dragging the tab across, or you can copy over the contents of cells as values-only but preserving formatting.

It could still do with a lot of work to make it better (better error-handling, general cleaning up), but it hopefully provides a good start.

Note that not all formatting is carried across because the new sheet uses its own theme's fonts and colours. I can't work out how to copy those across when pasting as values only.

Behe's answer with sorting plugins did not work on my Jenkins machine. I received the error java.lang.UnsupportedOperationException due to trying to sort an immutable collection i.e. Jenkins.instance.pluginManager.plugins. Simple fix for the code:

jenkinsPlugins.sort { it.displayName }
              .each { plugin ->
                   println ("${plugin.shortName}:${plugin.version}")
              }

v-model
it is two way data binding, it is used to bind html input element when you change input value then bounded data will be change.

v-model is used only for HTML input elements

ex: <input type="text" v-model="name" > 

v-bind
it is one way data binding,means you can only bind data to input element but can't change bounded data changing input element. v-bind is used to bind html attribute
ex:
<input type="text" v-bind:class="abc" v-bind:value="">

<a v-bind:href="home/abc" > click me </a>

CSS3: http://webdesign.about.com/od/styleproperties/p/blspbgsize.htm

.style1 {
  ...
  background-size: 100%;

You can specify just width or height with:

background-size: 100% 50%;

Which will stretch it 100% of the width and 50% of the height.

A new library called ts-optchain provides this functionality, and unlike lodash' solution, it also keeps your types safe, here is a sample of how it is used (taken from the readme):

import { oc } from 'ts-optchain';

interface I {
  a?: string;
  b?: {
    d?: string;
  };
  c?: Array<{
    u?: {
      v?: number;
    };
  }>;
  e?: {
    f?: string;
    g?: () => string;
  };
}

const x: I = {
  a: 'hello',
  b: {
    d: 'world',
  },
  c: [{ u: { v: -100 } }, { u: { v: 200 } }, {}, { u: { v: -300 } }],
};

// Here are a few examples of deep object traversal using (a) optional chaining vs
// (b) logic expressions. Each of the following pairs are equivalent in
// result. Note how the benefits of optional chaining accrue with
// the depth and complexity of the traversal.

oc(x).a(); // 'hello'
x.a;

oc(x).b.d(); // 'world'
x.b && x.b.d;

oc(x).c[0].u.v(); // -100
x.c && x.c[0] && x.c[0].u && x.c[0].u.v;

oc(x).c[100].u.v(); // undefined
x.c && x.c[100] && x.c[100].u && x.c[100].u.v;

oc(x).c[100].u.v(1234); // 1234
(x.c && x.c[100] && x.c[100].u && x.c[100].u.v) || 1234;

oc(x).e.f(); // undefined
x.e && x.e.f;

oc(x).e.f('optional default value'); // 'optional default value'
(x.e && x.e.f) || 'optional default value';

// NOTE: working with function value types can be risky. Additional run-time
// checks to verify that object types are functions before invocation are advised!
oc(x).e.g(() => 'Yo Yo')(); // 'Yo Yo'
((x.e && x.e.g) || (() => 'Yo Yo'))();

I want to make this function generic, without using ifs; is it possible?

The only simple way I see is to use overloading .. which is not available in C programming langage AFAIK.

Did you consider the C++ programming langage for your programm ? Or is there any constraint that forbids its use?

(Mar 2017) The accepted answer is not the best solution. It relies on manual translation using Apps Script, and the code may not be resilient, requiring maintenance. If your legacy system autogenerates CSV files, it's best they go into another folder for temporary processing (importing [uploading to Google Drive & converting] to Google Sheets files).

My thought is to let the Drive API do all the heavy-lifting. The Google Drive API team released v3 at the end of 2015, and in that release, insert() changed names to create() so as to better reflect the file operation. There's also no more convert flag -- you just specify MIMEtypes... imagine that!

The documentation has also been improved: there's now a special guide devoted to uploads (simple, multipart, and resumable) that comes with sample code in Java, Python, PHP, C#/.NET, Ruby, JavaScript/Node.js, and iOS/Obj-C that imports CSV files into Google Sheets format as desired.

Below is one alternate Python solution for short files ("simple upload") where you don't need the apiclient.http.MediaFileUpload class. This snippet assumes your auth code works where your service endpoint is DRIVE with a minimum auth scope of https://www.googleapis.com/auth/drive.file.

# filenames & MIMEtypes
DST_FILENAME = 'inventory'
SRC_FILENAME = DST_FILENAME + '.csv'
SHT_MIMETYPE = 'application/vnd.google-apps.spreadsheet'
CSV_MIMETYPE = 'text/csv'

# Import CSV file to Google Drive as a Google Sheets file
METADATA = {'name': DST_FILENAME, 'mimeType': SHT_MIMETYPE}
rsp = DRIVE.files().create(body=METADATA, media_body=SRC_FILENAME).execute()

Better yet, rather than uploading to My Drive, you'd upload to one (or more) specific folder(s), meaning you'd add the parent folder ID(s) to METADATA. (Also see the code sample on this page.) Finally, there's no native .gsheet "file" -- that file just has a link to the online Sheet, so what's above is what you want to do.

If not using Python, you can use the snippet above as pseudocode to port to your system language. Regardless, there's much less code to maintain because there's no CSV parsing. The only thing remaining is to blow away the CSV file temp folder your legacy system wrote to.

please try with below query

select id,numbers_from,created_date,amount_numbers,SMS_text 
from Test_Table
where 
convert(datetime, convert(varchar(10), created_date, 102))  <= convert(datetime,'2013-04-12')

MAMP 5.3, you will not find my.cnf and adding them does not work as that max_allowed_packet is stored in variables.

One solution can be:

1. Go to http://localhost/phpmyadmin
2. Go to SQL tab
3. Run SHOW VARIABLES and check the values, if it is small then run with big values

4. Run the following query, it set max_allowed_packet to 7gb:

   set global max_allowed_packet=268435456;

For some, you may need to increase the following values as well:

set global wait_timeout = 600;
set innodb_log_file_size =268435456;

Well, it is maybe not a really beautiful solution in the code, but it is really beautiful in the interface of your function. And it is also very efficient. It is ideal if the second is more important for you (for example, you are developing a library).

The trick is this:

1. A line A a = b.make(); is internally converted to a constructor of A, i.e. as if you had written A a(b.make());.
2. Now b.make() should result a new class, with a callback function.
3. This whole thing can be fine handled only by classes, without any template.

Here is my minimal example. Check only the main(), as you can see it is simple. The internals aren't.

From the viewpoint of the speed: the size of a Factory::Mediator class is only 2 pointers, which is more that 1 but not more. And this is the only object in the whole thing which is transferred by value.

#include <stdio.h>

class Factory {
  public:
    class Mediator;

    class Result {
      public:
        Result() {
          printf ("Factory::Result::Result()\n");
        };

        Result(Mediator fm) {
          printf ("Factory::Result::Result(Mediator)\n");
          fm.call(this);
        };
    };

    typedef void (*MakeMethod)(Factory* factory, Result* result);

    class Mediator {
      private:
        Factory* factory;
        MakeMethod makeMethod;

      public:
        Mediator(Factory* factory, MakeMethod makeMethod) {
          printf ("Factory::Mediator::Mediator(Factory*, MakeMethod)\n");
          this->factory = factory;
          this->makeMethod = makeMethod;
        };

        void call(Result* result) {
          printf ("Factory::Mediator::call(Result*)\n");
          (*makeMethod)(factory, result);
        };
    };
};

class A;

class B : private Factory {
  private:
    int v;

  public:
    B(int v) {
      printf ("B::B()\n");
      this->v = v;
    };

    int getV() const {
      printf ("B::getV()\n");
      return v;
    };

    static void makeCb(Factory* f, Factory::Result* a);

    Factory::Mediator make() {
      printf ("Factory::Mediator B::make()\n");
      return Factory::Mediator(static_cast<Factory*>(this), &B::makeCb);
    };
};

class A : private Factory::Result {
  friend class B;

  private:
    int v;

  public:
    A() {
      printf ("A::A()\n");
      v = 0;
    };

    A(Factory::Mediator fm) : Factory::Result(fm) {
      printf ("A::A(Factory::Mediator)\n");
    };

    int getV() const {
      printf ("A::getV()\n");
      return v;
    };

    void setV(int v) {
      printf ("A::setV(%i)\n", v);
      this->v = v;
    };
};

void B::makeCb(Factory* f, Factory::Result* r) {
      printf ("B::makeCb(Factory*, Factory::Result*)\n");
      B* b = static_cast<B*>(f);
      A* a = static_cast<A*>(r);
      a->setV(b->getV()+1);
    };

int main(int argc, char **argv) {
  B b(42);
  A a = b.make();
  printf ("a.v = %i\n", a.getV());
  return 0;
}

Equivalent memory allocation for char a[10][20] would be as follows.

char **a;

a=(char **) malloc(10*sizeof(char *));

for(i=0;i<10;i++)
    a[i]=(char *) malloc(20*sizeof(char));

I hope this looks simple to understand.

Had a similar problem. My solution was to give the inner table a fixed height of 1px and set the height of the td in the inner table to 100%. Against all odds, it works fine, tested in IE, Chrome and FF!

I had this similar problem in a coding competition and this is how I handled it. Setting a precision of 2 to all double values

First adding the header to use setprecision

#include <iomanip>

Then adding the following code in our main

  double answer=5.9999;
  double answer2=5.0000;
  cout<<setprecision(2)<<fixed;
  cout <<answer << endl;
  cout <<answer2 << endl;

Output:

5.99
5.00

You need to use fixed for writing 5.00 thats why,your output won't come for 5.00.

A short reference video link I'm adding which is helpful

I see this is a fairly old question, but this looks like one of those times when something's been written without knowledge of a language feature. The collections library exists to fulfill these purposes.

from collections import Counter
letter_counter = Counter()
for letter in 'The quick brown fox jumps over the lazy dog':
    letter_counter[letter] += 1

>>> letter_counter
Counter({' ': 8, 'o': 4, 'e': 3, 'h': 2, 'r': 2, 'u': 2, 'T': 1, 'a': 1, 'c': 1, 'b': 1, 'd': 1, 'g': 1, 'f': 1, 'i': 1, 'k': 1, 'j': 1, 'm': 1, 'l': 1, 'n': 1, 'q': 1, 'p': 1, 's': 1, 't': 1, 'w': 1, 'v': 1, 'y': 1, 'x': 1, 'z': 1})

In this example the spaces are being counted, obviously, but whether or not you want those filtered is up to you.

As for the dict.get(a_key, default_value), there have been several answers to this particular question -- this method returns the value of the key, or the default_value you supply. The first argument is the key you're looking for, the second argument is the default for when that key is not present.

I'm not able to comment (too little reputation? I'm pretty new) on Lukas' post.

On my PG setup to_number(NULL) does not work, so my solution would be:

SELECT CASE WHEN column = NULL THEN NULL ELSE column :: Integer END
FROM table

I've put this answer on a similar question that was marked as a duplicate of this question. The answer has helped a decent amount of people so I thought I'd add it here too in just in case.

This doesn't exactly answer the question but for anyone using AngularJS trying to achieve this, the answer is slightly different. And actually the normal answer won't work (at least it didn't for me).

Your html will look pretty similar to the normal radio button:

<input type='radio' name='group' ng-model='mValue' value='first' />First
<input type='radio' name='group' ng-model='mValue' value='second' /> Second

In your controller you'll have declared the mValue that is associated with the radio buttons. To have one of these radio buttons preselected, assign the $scope variable associated with the group to the desired input's value:

$scope.mValue="second"

This makes the "second" radio button selected on loading the page.

If you're using IDLE, you can use Ctrl+] to indent and Ctrl+[ to unindent.

CSS will skip over style declarations it doesn't understand. Mozilla-based browsers will not understand -webkit-prefixed declarations, and WebKit-based browsers will not understand -moz-prefixed declarations.

Because of this, we can simply declare width twice:

elem {
    width: 100%;
    width: -moz-available;          /* WebKit-based browsers will ignore this. */
    width: -webkit-fill-available;  /* Mozilla-based browsers will ignore this. */
    width: fill-available;
}

The width: 100% declared at the start will be used by browsers which ignore both the -moz and -webkit-prefixed declarations or do not support -moz-available or -webkit-fill-available.

As others have mentioned, this is an old thread and even with this thread there tends to be different solutions that worked for different people. The solution that worked for is as follows:

Right Click Project Name > Properties
Linker > General 
Output File > $(OutDir)$(TargetName)$(TargetExt) as indicated by @ReturnVoid
Click Apply

For whatever reason this initial correction didn't fix my problem (I'm using VS2015 Community to build c++ program). If you still get the error message try the following additional steps:

Back in Project > Properties > Linker > General > Output File > 

You'll see the previously entered text in bold

Select Drop Down > Select "inherit from parent or project defaults"
Select Apply

Previously bold font is no longer bold

Build > Rebuild > Debug

It doesn't make since to me to require these additional steps in addition to what @ReturnVoid posted but...what works is what works...hope it helps someone else out too. Thanks @ReturnVoid

try this function

public static Date StringToDate(String strDate) throws ModuleException {
    Date dtReturn = null;
    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-mm-dd");
    try {
        dtReturn = simpleDateFormat.parse(strDate);
    } catch (ParseException e) {
        e.printStackTrace();
    }
    return dtReturn;
}

You can change project facet from Project --> Properties --> Project Facet --> Java --> {required JDK version}

The response itself seems to have the size of the records. You can use that to check if records exist. Something like:

if($response->size > 0){
    $role_arr = getRole($response->records);
}

Self-explanatory code follows which first creates a std::tm corresponding to 10-10-2012 12:38:40, converts that to a std::chrono::system_clock::time_point, adds 0.123456 seconds, and then prints that out by converting back to a std::tm. How to handle the fractional seconds is in the very last step.

#include <iostream>
#include <chrono>
#include <ctime>

int main()
{
    // Create 10-10-2012 12:38:40 UTC as a std::tm
    std::tm tm = {0};
    tm.tm_sec = 40;
    tm.tm_min = 38;
    tm.tm_hour = 12;
    tm.tm_mday = 10;
    tm.tm_mon = 9;
    tm.tm_year = 112;
    tm.tm_isdst = -1;
    // Convert std::tm to std::time_t (popular extension)
    std::time_t tt = timegm(&tm);
    // Convert std::time_t to std::chrono::system_clock::time_point
    std::chrono::system_clock::time_point tp = 
                                     std::chrono::system_clock::from_time_t(tt);
    // Add 0.123456 seconds
    // This will not compile if std::chrono::system_clock::time_point has
    //   courser resolution than microseconds
    tp += std::chrono::microseconds(123456);
    
    // Now output tp

    // Convert std::chrono::system_clock::time_point to std::time_t
    tt = std::chrono::system_clock::to_time_t(tp);
    // Convert std::time_t to std::tm (popular extension)
    tm = std::tm{0};
    gmtime_r(&tt, &tm);
    // Output month
    std::cout << tm.tm_mon + 1 << '-';
    // Output day
    std::cout << tm.tm_mday << '-';
    // Output year
    std::cout << tm.tm_year+1900 << ' ';
    // Output hour
    if (tm.tm_hour <= 9)
        std::cout << '0';
    std::cout << tm.tm_hour << ':';
    // Output minute
    if (tm.tm_min <= 9)
        std::cout << '0';
    std::cout << tm.tm_min << ':';
    // Output seconds with fraction
    //   This is the heart of the question/answer.
    //   First create a double-based second
    std::chrono::duration<double> sec = tp - 
                                    std::chrono::system_clock::from_time_t(tt) +
                                    std::chrono::seconds(tm.tm_sec);
    //   Then print out that double using whatever format you prefer.
    if (sec.count() < 10)
        std::cout << '0';
    std::cout << std::fixed << sec.count() << '\n';
}

For me this outputs:

10-10-2012 12:38:40.123456

Your std::chrono::system_clock::time_point may or may not be precise enough to hold microseconds.

Update

An easier way is to just use this date library. The code simplifies down to (using C++14 duration literals):

#include "date.h"
#include <iostream>
#include <type_traits>

int
main()
{
    using namespace date;
    using namespace std::chrono;
    auto t = sys_days{10_d/10/2012} + 12h + 38min + 40s + 123456us;
    static_assert(std::is_same<decltype(t),
                               time_point<system_clock, microseconds>>{}, "");
    std::cout << t << '\n';
}

which outputs:

2012-10-10 12:38:40.123456

You can skip the static_assert if you don't need to prove that the type of t is a std::chrono::time_point.

If the output isn't to your liking, for example you would really like dd-mm-yyyy ordering, you could:

#include "date.h"
#include <iomanip>
#include <iostream>

int
main()
{
    using namespace date;
    using namespace std::chrono;
    using namespace std;
    auto t = sys_days{10_d/10/2012} + 12h + 38min + 40s + 123456us;
    auto dp = floor<days>(t);
    auto time = make_time(t-dp);
    auto ymd = year_month_day{dp};
    cout.fill('0');
    cout << ymd.day() << '-' << setw(2) << static_cast<unsigned>(ymd.month())
         << '-' << ymd.year() << ' ' << time << '\n';
}

which gives exactly the requested output:

10-10-2012 12:38:40.123456

Update

Here is how to neatly format the current time UTC with milliseconds precision:

#include "date.h"
#include <iostream>

int
main()
{
    using namespace std::chrono;
    std::cout << date::format("%F %T\n", time_point_cast<milliseconds>(system_clock::now()));
}

which just output for me:

2016-10-17 16:36:02.975

C++17 will allow you to replace time_point_cast<milliseconds> with floor<milliseconds>. Until then date::floor is available in "date.h".

std::cout << date::format("%F %T\n", date::floor<milliseconds>(system_clock::now()));

Update C++20

In C++20 this is now simply:

#include <chrono>
#include <iostream>

int
main()
{
    using namespace std::chrono;
    auto t = sys_days{10d/10/2012} + 12h + 38min + 40s + 123456us;
    std::cout << t << '\n';
}

Or just:

std::cout << std::chrono::system_clock::now() << '\n';

std::format will be available to customize the output.

The solution for multi-indexes is inside jezrael's cyclopedic answer, but it took me a while to find it so I am posting a new answer:

    Fixed a bug in space world automation

and you want to merge the top two commits just do following easy steps:

1. First to be on safe side checkout the second last commit in a separate branch. You can name the branch anything. git checkout 77df2a40e53136c7a2d58fd847372 -b merged-commits
2. Now, just cherry-pick your changes from the last commit into this new branch as: git cherry-pick -n -x ac72a4308ba70cc42aace47509a5e. (Resolve conflicts if arise any)
3. So now, your changes in last commit are there in your second last commit. But you still have to commit, so first add the changes you just cherry-picked and then execute git commit --amend.

That's it. You may push this merged version in branch "merged-commits" if you like.

Also, you can discard the back-to-back two commits in your master branch now. Just update your master branch as:

git checkout master
git reset --hard origin/master (CAUTION: This command will remove any local changes to your master branch)
git pull

Got a gotcha for those with their headspace in Pandas and moving to pyspark

 from pyspark import SparkConf, SparkContext
 from pyspark.sql import SQLContext

 spark_conf = SparkConf().setMaster("local").setAppName("MyAppName")
 sc = SparkContext(conf = spark_conf)
 sqlContext = SQLContext(sc)

 records = [
     {"colour": "red"},
     {"colour": "blue"},
     {"colour": None},
 ]

 pandas_df = pd.DataFrame.from_dict(records)
 pyspark_df = sqlContext.createDataFrame(records)

So if we wanted the rows that are not red:

pandas_df[~pandas_df["colour"].isin(["red"])]

Looking good, and in our pyspark DataFrame

pyspark_df.filter(~pyspark_df["colour"].isin(["red"])).collect()

So after some digging, I found this: https://issues.apache.org/jira/browse/SPARK-20617 So to include nothingness in our results:

pyspark_df.filter(~pyspark_df["colour"].isin(["red"]) | pyspark_df["colour"].isNull()).show()

You need to login to your mysql terminal first using mysql -u username -p password

Then use this:

SELECT @@sql_mode; or SELECT @@GLOBAL.sql_mode;

output will be like this:

STRICT_TRANS_TABLES,STRICT_ALL_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,TRADITIONAL,NO_AUTO_CREATE_USER,NO_ENGINE_SUB

You can also set sql mode by this:

SET GLOBAL sql_mode=TRADITIONAL;

You can simply do:

"123456".Select(q => new string(q,1)).ToArray();

to have an enumerable of integers, as per comment request, you can:

"123456".Select(q => int.Parse(new string(q,1))).ToArray();

It is a little weak since it assumes the string actually contains numbers.

You can use the following approaches-

var obj = {a:1}
console.log('a' in obj)               // 1
console.log(obj.hasOwnProperty('a'))  // 2
console.log(Boolean(obj.a))         // 3

The difference between the following approaches are as follows-

1. In the first and third approach we are not just searching in object but its prototypal chain too. If the object does not have the property, but the property is present in its prototype chain it is going to give true.

var obj = {
    a: 2,
    __proto__ : {b: 2}
}

console.log('b' in obj)
console.log(Boolean(obj.b))

2. The second approach will check only for its own properties. Example -

var obj = {
    a: 2,
    __proto__ : {b: 2}
}

console.log(obj.hasOwnProperty('b'))

3. The difference between the first and the third is if there is a property which has value undefined the third approach is going to give false while first will give true.

var obj = {
    b : undefined
}

console.log(Boolean(obj.b))
console.log('b' in obj);

select controls are still clickable even on readonly attrib

if you want to still disable the control but you want its value posted. You might consider creating a hidden field. with the same value as your control.

then create a jquery, on select change

$('#your_select_id').change(function () {
    $('#your_hidden_selectid').val($('#your_select_id').val());
});

A simple way to see remote branches is:

git branch -r

To see local branches:

git branch -l

Consider this as the current update (Windows 10 (Version 1803) and Visual Studio 2017): I was unable to view the stack trace window and did find an option/menu item to view it. On investigating further, it seems this feature is not available on Windows 10. For further information please refer:

https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/viewing-the-call-stack-in-visual-studio

Copied from the above link: "This feature is not available in Windows 10, version 1507 and later versions of the WDK."

Here's another pure bash solution:

• it's using heredoc, so:
  • complexity doesn't increase because of additionaly required syntax
  • template can include bash code
    • that also allows you to indent stuff properly. See below.
• it doesn't use eval, so:
  • no problems with the rendering of trailing empty lines
  • no problems with quotes in the template

$ cat code

#!/bin/bash
LISTING=$( ls )

cat_template() {
  echo "cat << EOT"
  cat "$1"
  echo EOT
}

cat_template template | LISTING="$LISTING" bash

$ cat template (with trailing newlines and double quotes)

<html>
  <head>
  </head>
  <body> 
    <p>"directory listing"
      <pre>
$( echo "$LISTING" | sed 's/^/        /' )
      <pre>
    </p>
  </body>
</html>

output

<html>
  <head>
  </head>
  <body> 
    <p>"directory listing"
      <pre>
        code
        template
      <pre>
    </p>
  </body>
</html>

I had problems with all above solutions. Finally i used aspectRatio to do the trick. When you know image width and height and they are large, just calculate aspectRatio and add it to image like:

<PhotoImage
    source={{uri: `data:image/jpeg;base64,${image.base64}`}}
    style={{ aspectRatio: image.width / image.height }}
 />

AspectRatio is a layout property of React Native, to keep aspect ratio of image and fit into parent container: https://facebook.github.io/react-native/docs/layout-props#aspectratio

When you use a function ...

<p onclick="update_url('/en/step2');">Link</p>

<script>
function update_url(url) {
    history.pushState(null, null, url);
}
</script>

Use setInterval:

$(function(){
setInterval(oneSecondFunction, 1000);
});

function oneSecondFunction() {
// stuff you want to do every second
}

Here's an article on the difference between setTimeout and setInterval. Both will provide the functionality you need, they just require different implementations.

You have to close that application first. There is no way to delete it, if it's used by some application.

UnLock IT is a neat utility that helps you to take control of any file or folder when it is locked by some application or system. For every locked resource, you get a list of locking processes and can unlock it by terminating those processes. EMCO Unlock IT offers Windows Explorer integration that allows unlocking files and folders by one click in the context menu.

There's also Unlocker (not recommended, see Warning below), which is a free tool which helps locate any file locking handles running, and give you the option to turn it off. Then you can go ahead and do anything you want with those files.

Warning: The installer includes a lot of undesirable stuff. You're almost certainly better off with UnLock IT.

Lets say you just want the first char from a part of $_POST, lets call it 'type'. And that $_POST['type'] is currently 'Control'. If in this case if you use $_POST['type'][0], or substr($_POST['type'], 0, 1)you will get C back.

However, if the client side were to modify the data they send you, from type to type[] for example, and then send 'Control' and 'Test' as the data for this array, $_POST['type'][0] will now return Control rather than C whereas substr($_POST['type'], 0, 1) will simply just fail.

So yes, there may be a problem with using $str[0], but that depends on the surrounding circumstance.

In case that you need to add the http redirect in many sites, you could use it as a c# console program:

   class Program
{
    static int Main(string[] args)
    {
        if (args.Length < 3)
        {
            Console.WriteLine("Please enter an argument: for example insert-redirect ./web.config http://stackoverflow.com");
            return 1;
        }

        if (args.Length == 3)
        {
            if (args[0].ToLower() == "-insert-redirect")
            {
                var path = args[1];
                var value = args[2];

                if (InsertRedirect(path, value))
                    Console.WriteLine("Redirect added.");
                return 0;
            }
        }

        Console.WriteLine("Wrong parameters.");
        return 1;

    }

    static bool InsertRedirect(string path, string value)
    {
        try
        {
            XmlDocument doc = new XmlDocument();

            doc.Load(path);

            // This should find the appSettings node (should be only one):
            XmlNode nodeAppSettings = doc.SelectSingleNode("//system.webServer");

            var existNode = nodeAppSettings.SelectSingleNode("httpRedirect");
            if (existNode != null)
                return false;

            // Create new <add> node
            XmlNode nodeNewKey = doc.CreateElement("httpRedirect");

            XmlAttribute attributeEnable = doc.CreateAttribute("enabled");
            XmlAttribute attributeDestination = doc.CreateAttribute("destination");
            //XmlAttribute attributeResponseStatus = doc.CreateAttribute("httpResponseStatus");

            // Assign values to both - the key and the value attributes:

            attributeEnable.Value = "true";
            attributeDestination.Value = value;
            //attributeResponseStatus.Value = "Permanent";

            // Add both attributes to the newly created node:
            nodeNewKey.Attributes.Append(attributeEnable);
            nodeNewKey.Attributes.Append(attributeDestination);
            //nodeNewKey.Attributes.Append(attributeResponseStatus);

            // Add the node under the 
            nodeAppSettings.AppendChild(nodeNewKey);
            doc.Save(path);

            return true;
        }
        catch (Exception e)
        {
            Console.WriteLine($"Exception adding redirect: {e.Message}");
            return false;
        }
    }
}

If you have a URL, you can pass url.toString() into this method. First decode, to avoid double encoding (for example, encoding a space results in %20 and encoding a percent sign results in %25, so double encoding will turn a space into %2520). Then, use the URI as explained above, adding in all the parts of the URL (so that you don't drop the query parameters).

public URL convertToURLEscapingIllegalCharacters(String string){
    try {
        String decodedURL = URLDecoder.decode(string, "UTF-8");
        URL url = new URL(decodedURL);
        URI uri = new URI(url.getProtocol(), url.getUserInfo(), url.getHost(), url.getPort(), url.getPath(), url.getQuery(), url.getRef()); 
        return uri.toURL(); 
    } catch (Exception ex) {
        ex.printStackTrace();
        return null;
    }
}

you can call mysql_fetch_array() for no_of_row time

Pretty strange, it should work out of the box as the ".modal-backdrop" class is defined top-level in the css.

<div class="modal-backdrop"></div>

Made a small demo: http://jsfiddle.net/PfBnq/

This method uses a tidyverse package (purrr).

The list:

x <- as.list(mtcars)

Converting it into a data frame (a tibble more specifically):

Use the <shape> tag to create a drawable in XML with rounded corners. (You can do other stuff with the shape tag like define a color gradient as well).

Here's a copy of a XML file I'm using in one of my apps to create a drawable with a white background, black border and rounded corners:

<?xml version="1.0" encoding="UTF-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
    <solid android:color="#ffffffff"/>    
             
    <stroke android:width="3dp"
            android:color="#ff000000" />

    <padding android:left="1dp"
             android:top="1dp"
             android:right="1dp"
             android:bottom="1dp" /> 
             
    <corners android:radius="7dp" /> 
</shape>

The problem with your code is in your loop in Check_Circular. You are advancing through the list using n1 by going one node at a time. By reassigning n2 to n2.next.next you are advancing through it two at a time.

When you do that, n2.next.next may be null, so n2 will be null after the assignment. When the loop repeats and it checks if n2.next is not null, it throws the NPE because it can't get to next since n2 is already null.

You want to do something like what Alex posted instead.

setTimeout('$("#someDivId").hide()',1500);

• props --- you can not change its value.
• states --- you can change its value in your code, but it would be active when a render happens.

At least on 10.10.5, system_profiler SPUSBDataType output is NOT dynamically updated when a new USB device gets plugged in, while ioreg -p IOUSB -l -w 0 does.

If you are use nginx try this

#Control-Allow-Origin access

    # Authorization headers aren't passed in CORS preflight (OPTIONS) calls. Always return a 200 for options.
    add_header Access-Control-Allow-Credentials "true" always;
    add_header Access-Control-Allow-Origin "https://URL-WHERE-ORIGIN-FROM-HERE " always;
    add_header Access-Control-Allow-Methods "GET,OPTIONS" always;
    add_header Access-Control-Allow-Headers "x-csrf-token,authorization,content-type,accept,origin,x-requested-with,access-control-allow-origin" always;

    if ($request_method = OPTIONS ) {
        return 200;
    }

You can also use

   $(document).ready(function() {

    //some even that will run ajax request - for example click on a button

    var uname = $('#username').val();
    $.ajax({
    type: 'POST',
    url: 'func.php', //this should be url to your PHP file
    dataType: 'html',
    data: {func: 'toptable', user_id: uname},
    beforeSend: function() {
        $('#right').html('checking');
    },
    complete: function() {},
    success: function(html) {
        $('#right').html(html);
    }
    });

    });
And your func.php:

  function toptable()
 {
  echo 'something happens in here';
 }

Hope it helps somebody

We should rather use Javascript.

    <button href="images/car.jpg" id="myButton">
        Here is the Button to be clicked
    </button>


    <script>

        $(document).ready(function(){
            document.getElementById("myButton").click();
        });

    </script>

I'm going to answer my own question.

1. innerJoin should use the keyword "WITH" instead of "ON" (Doctrine's documentation [13.2.6. Helper methods] is inaccurate; [13.2.5. The Expr class] is correct)
2. no need to link foreign keys in join condition as they're already specified in the entity mapping.

Therefore, the following works for me

$qb->select('c')
    ->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
    ->where('c.username = :username');

or

$qb->select('c')
    ->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
    ->where('c.username = :username');

See Should my constructors use "initialization lists" or "assignment"?

Briefly: in your specific case, it does not change anything. But:

• for class/struct members with constructors, it may be more efficient to use option 1.
• only option 1 allows you to initialize reference members.
• only option 1 allows you to initialize const members
• only option 1 allows you to initialize base classes using their constructor
• only option 2 allows you to initialize array or structs that do not have a constructor.

My guess for why option 2 is more common is that option 1 is not well-known, neither are its advantages. Option 2's syntax feels more natural to the new C++ programmer.

Use a simple background image for the textarea suffice.

Or

<div onselectstart="return false">your text</div>

It seems none of the current answers will actually remove 100% of whitespace from the start and end of a string.

As mentioned in other posts, the default TRIM only removes spaces - not tabs, formfeeds etc. A combination of TRIMs specifying other whitespace characters may provide a limited improvement e.g. TRIM(BOTH '\r' FROM TRIM(BOTH '\n' FROM TRIM(BOTH '\f' FROM TRIM(BOTH '\t' FROM TRIM(txt))))). But the problem with this approach is only a single character can be specified for a particular TRIM and those characters are only removed from the start and end. So if the string being trimmed is something like \t \t \t \t (i.e. alternate spaces and tab characters), more TRIMs would be needed - and in the general case this could go on indefinitely.

For a lightweight solution, it should be possible to write a simple User Defined Function (UDF) to do the job by looping through the characters at the start and end of a string. But I'm not going to do that... as I've already written a rather more heavyweight regular expression replacer which can also do the job - and may come in useful for other reasons, as described in this blog post.

I had the same problem as yours. I found that when i use the BoundField tag in GridView to show my data. The row.Cells[1].Text is working in:

GridViewRow row = dgCustomer.SelectedRow;
TextBox1.Text = "Cell Value" + row.Cells[1].Text + "";

But when i use TemplateField tag to show data like this:

 <asp:TemplateField HeaderText="??">
    <ItemTemplate>
    <asp:Label ID="Part_No" runat="server" Text='<%# Eval("Part_No")%>' ></asp:Label>
    </ItemTemplate>
    <HeaderStyle CssClass="bhead" />
    <ItemStyle CssClass="bbody" />
    </asp:TemplateField>

The row.Cells[1].Text just return null. I got stuck in this problem for a long time. I figur out recently and i want to share with someone who have the same problem my solution. Please feel free to edit this post and/or correct me.

My Solution:

Label lbCod = GridView1.Rows["AnyValidIndex"].Cells["AnyValidIndex"].Controls["AnyValidIndex"] as Label;

I use Controls attribute to find the Label control which i use to show data, and you can find yours. When you find it and convert to the correct type object than you can extract text and so on. Ex:

string showText = lbCod.Text;

Reference: reference

Try this:

String str="name=john age=13 year=2001";
String s[]=str.split(" ");
StringBuilder v=new StringBuilder();
for (String string : s) {
    v.append(string);
}
str=v.toString();

Since nobody so far felt fit to point out why what you're trying doesn't work:

1. NA == NA doesn't return TRUE, it returns NA (since comparing to undefined values should yield an undefined result).
2. You're trying to call apply on an atomic vector. You can't use apply to loop over the elements in a column.
3. Your subscripts are off - you're trying to give two indices into a$x, which is just the column (an atomic vector).

I'd fix up 3. to get to a$x[is.na(a$x)] <- 0

You can use find option to select an element inside another. For example, to find an element with id txtName in a particular div, you can use like

var name = $('#div1').find('#txtName').val();

Like this:

border: 1px solid black;

Why it didn't work? because:

Always declare the border-style (solid in my example) property before the border-width property. An element must have borders before you can change the color.

In addition to what others have said,

SET YOUR LABEL'S CONSTRAINTS RELATIVE TO THE SUPERVIEW!

So instead of placing your label's constraints relative to other things around it, constrain it to the table view cell's content view.

Then, make sure your label's height is set to more than or equal 0, and the number of lines is set to 0.

Then in ViewDidLoad add:

tableView.estimatedRowHeight = 695

tableView.rowHeight = UITableViewAutomaticDimension

It's even easier in Windows 8.1 and Server 2012 R2.

Do this once: Right-click on the task bar, choose Properties. In the Navigation tab, turn on [✓] Replace Command Prompt with Windows PowerShell in the menu when I right-click the lower-left corner or press Windows key+X.

Then whenever you want a PowerShell prompt, hit Win+X, I. (Or Win+X, A for an Admin PowerShell prompt)

Application.SetOption "Auto compact", False '(mentioned above) Use this with a button caption: "DB Not Compact On Close"

Write code to toggle the caption with "DB Compact On Close" along with Application.SetOption "Auto compact", True

AutoCompact can be set by means of the button or by code, ex: after importing large temp tables.

The start up form can have code that turns off Auto Compact, so that it doesn't run every time.

This way, you are not trying to fight Access.

Start to look at the execution plans to see the differences in how the SQl Server will interpret them. You can also use Profiler to actually run the queries multiple times and get the differnce.

I would not expect these to be so horribly different, where you can get get real, large performance gains in using joins instead of subqueries is when you use correlated subqueries.

EXISTS is often better than either of these two and when you are talking left joins where you want to all records not in the left join table, then NOT EXISTS is often a much better choice.

As explained in other answers, to use this ParameterizedType approach, you need to extend the class, but that seems like extra work to make a whole new class that extends it...

So, making the class abstract it forces you to extend it, thus satisfying the subclassing requirement. (using lombok's @Getter).

@Getter
public abstract class ConfigurationDefinition<T> {

    private Class<T> type;
    ...

    public ConfigurationDefinition(...) {
        this.type = (Class<T>) ((ParameterizedType) this.getClass().getGenericSuperclass()).getActualTypeArguments()[0];
        ...
    }
}

Now to extend it without defining a new class. (Note the {} on the end... extended, but don't overwrite anything - unless you want to).

private ConfigurationDefinition<String> myConfigA = new ConfigurationDefinition<String>(...){};
private ConfigurationDefinition<File> myConfigB = new ConfigurationDefinition<File>(...){};
...
Class stringType = myConfigA.getType();
Class fileType = myConfigB.getType();

because the OR operator will return true if any one of the conditions is true, and in your code there are two conditions that are true.

You add to the back state from the FragmentTransaction and remove from the backstack using FragmentManager pop methods:

FragmentManager manager = getActivity().getSupportFragmentManager();
FragmentTransaction trans = manager.beginTransaction();
trans.remove(myFrag);
trans.commit();
manager.popBackStack();

Use option bty = "n" in legend to remove the box around the legend. For example:

legend(1, 5,
       "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",
       bty = "n")

Do you have bluestacks installed? If you do, the background processes that it runs creates the offline device "emulator-5554".

Go to the task manager and end all the processes with the description of "Bluestacks"

Try this

string stringToCheck = "text1text2text3";
string[] stringArray = new string[] { "text1" };

var t = lines.ToList().Find(c => c.Contains(stringToCheck));

It will return you the line with the first incidence of the text that you are looking for.

OK It's A Wrong Approach But If You Use it Like This :

compile "com.android.support:appcompat-v7:+"

Android Studio Will Use The Last Version It Has.

In My Case Was 26.0.0alpha-1.

You Can See The Used Version In External Libraries (In The Project View).

I Tried Everything But Couldn't Use Anything Above 26.0.0alpha-1, It Seems My IP Is Blocked By Google. Any Idea? Comment

Your data.frame mat is rectangular (n_rows!= n_cols).

Therefore, you cannot make a data.frame out of the column- and rownames, because each column in a data.frame must be the same length.

Maybe this suffices your needs:

require(reshape2)
mat$id <- rownames(mat) 
melt(mat)

I just hit this issue myself, and neither this nor any of the other answers on the net solved my issue. For me it was a strange one whereby the virtual directory had been created on a different branch in another source control server (basically, we upgraded from TFS 2010 to 2013) and the solution somehow remembered it's mapping.

Anyway, I clicked the "Create Virtual Directory" button again, in the Properties of the Service project. It gave me a message about being mapped to a different folder and would I like to update it. I clicked yes, and that fixed the issue.

I determined that this problem was a corrupt connection manager by identifying the specific connection that was failing. I'm working in SQL Server 2016 and I have created the SSISDB catalog and I am deploying my projects there.

Here's the short answer. Delete the connection manager and then re-create it with the same name. Make sure the packages using that connection are still wired up correctly and you should be good to go. If you're not sure how to do that, I've included the detailed procedure below.

To identify the corrupt connection, I did the following. In SSMS, I opened the Integration Services Catalogs folder, then the SSISDB folder, then the folder for my solution, and on down until I found my list of packages for that project.

By right clicking the package that failed, going to reports>standard reports>all executions, selecting the last execution, and viewing the "All Messages" report I was able to isolate which connection was failing. In my case, the connection manager to my destination. I simply deleted the connection manager and then recreated a new connection manager with the same name.

Subsequently, I went into my package, opened the data flow, found that some of my destinations had lit up with the red X. I opened the destination, re-selected the correct connection name, re-selected the target table, and checked the mappings were still correct. I had six destinations and only three had the red X but I clicked all of them and made sure they were still configured correctly.

Since this question is quite old, but still comes up in google searches, I thought it would be good to point out the newer (and recommended) way to save Keras models. Instead of saving them using the older h5 format like has been shown before, it is now advised to use the SavedModel format, which is actually a dictionary that contains both the model configuration and the weights.

More information can be found here: https://www.tensorflow.org/guide/keras/save_and_serialize

The snippets to save & load can be found below:

model.fit(test_input, test_target)
# Calling save('my_model') creates a SavedModel folder 'my_model'.
model.save('my_model')

# It can be used to reconstruct the model identically.
reconstructed_model = keras.models.load_model('my_model')

A sample output of this :

You can add that line to your console config file (e.g. .bashrc) , or to .profile

The answer given by minrk (included for completeness) is good, but there is another way that I like even more.

You can also render an entire cell as LaTeX by typing %%latex as the first line in a text cell. This is usefull if you

• want more control,
• want more than just a math environment,
• or if you are going to write a lot of math in one cell.

minrk's answer:

IPython notebook uses MathJax to render LaTeX inside html/markdown. Just put your LaTeX math inside $$.

$$c = \sqrt{a^2 + b^2}$$

Or you can display LaTeX / Math output from Python, as seen towards the end of the notebook tour:

from IPython.display import display, Math, Latex
display(Math(r'F(k) = \int_{-\infty}^{\infty} f(x) e^{2\pi i k} dx'))

30x30 is points, which means 30px @1x, 60px @2x, not somewhere in-between. Also, it's not a great idea to embed the title of the tab into the image—you're going to have pretty poor accessibility and localization results like that.

You might want to take a look this:

HotSwap support: the object-oriented architecture of the Java HotSpot VM enables advanced features such as on-the-fly class redefinition, or "HotSwap". This feature provides the ability to substitute modified code in a running application through the debugger APIs. HotSwap adds functionality to the Java Platform Debugger Architecture, enabling a class to be updated during execution while under the control of a debugger. It also allows profiling operations to be performed by hotswapping in versions of methods in which profiling code has been inserted.

For the moment, this only allows for newly compiled method body to be redeployed without restarting the application. All you have to do is to run it with a debugger. I tried it in Eclipse and it works splendidly.

Also, as Emmanuel Bourg mentioned in his answer (JEP 159), there is hope to have support for the addition of supertypes and the addition and removal of methods and fields.

To select the item from the contextual menu, you have to just move your mouse positions with the use of Key down event like this:-

Actions action= new Actions(driver);
action.contextClick(productLink).sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.RETURN).build().perform();

hope this will works for you. Have a great day :)

Using getcwd() to extract in the same directory

<?php
$unzip = new ZipArchive;
$out = $unzip->open('wordpress.zip');
if ($out === TRUE) {
  $unzip->extractTo(getcwd());
  $unzip->close();
  echo 'File unzipped';
} else {
  echo 'Error';
}
?>

This is the format I used to exclude some paths:

$ find ./ -type f -name "pattern" ! -path "excluded path" ! -path "excluded path"

I used this to find all files not in ".*" paths:

$ find ./ -type f -name "*" ! -path "./.*" ! -path "./*/.*"

Simply use this:

public static List<String> GetAllFiles(String directory)
{
    return Directory.GetFiles(directory, "*.*", SearchOption.AllDirectories).ToList();
}

And if you want every file, even extensionless ones:

public static List<String> GetAllFiles(String directory)
{
    return Directory.GetFiles(directory, "*", SearchOption.AllDirectories).ToList();
}

Type "msg /?" in the command prompt to get various ways of sending meessages to a user.

Type "net send /?" in the command prompt to get another variation of sending messages across.

You can use a third-party library like base64-img or base64-to-image.

1. base64-img

const base64Img = require('base64-img');

const data = 'data:image/png;base64,...';
const destpath = 'dir/to/save/image';
const filename = 'some-filename';

base64Img.img(data, destpath, filename, (err, filepath) => {}); // Asynchronous using

const filepath = base64Img.imgSync(data, destpath, filename); // Synchronous using

2. base64-to-image

const base64ToImage = require('base64-to-image');

const base64Str = 'data:image/png;base64,...';
const path = 'dir/to/save/image/'; // Add trailing slash
const optionalObj = { fileName: 'some-filename', type: 'png' };

const { imageType, fileName } = base64ToImage(base64Str, path, optionalObj); // Only synchronous using

I know this is an old thread, but hope it helps some one.

public static void SetRequest(string mXml)
{
    HttpWebRequest webRequest = (HttpWebRequest)HttpWebRequest.CreateHttp("http://dork.com/service");
    webRequest.Method = "POST";
    webRequest.Headers["SOURCE"] = "WinApp";

    // Decide your encoding here

    //webRequest.ContentType = "application/x-www-form-urlencoded";
    webRequest.ContentType = "text/xml; charset=utf-8";

    // You should setContentLength
    byte[] content = System.Text.Encoding.UTF8.GetBytes(mXml);
    webRequest.ContentLength = content.Length;

    var reqStream = await webRequest.GetRequestStreamAsync();
    reqStream.Write(content, 0, content.Length);

    var res = await httpRequest(webRequest);
}

There's a problem with immediate asynchronous call of your function, because standard setTimeout/setInterval has a minimal timeout about several milliseconds even if you directly set it to 0. It caused by a browser specific work.

An example of code with a REAL zero delay wich works in Chrome, Safari, Opera

function setZeroTimeout(callback) {
var channel = new MessageChannel();
channel.port1.onmessage = callback;
channel.port2.postMessage('');
}

You can find more information here

And after the first manual call you can create an interval with your function.

I ran into this issue using laravel datatables. I was storing a JSON value called properties in an activity log and wanted to show a button based on this value being empty or not.

Well, datatables was interpreting this as an array if it was empty, and an object if it was not, therefore, the following solution worked for me:

render: function (data, type, full) {
    if (full.properties.length !== 0) {
        // do stuff
    }
}

An object does not have a length property.

You can get NaN from "inf - inf", and you can get "inf" from a number greater than 2e308, so, I generally used:

>>> inf = 9e999
>>> inf
inf
>>> inf - inf
nan

try this

df.rename(columns={ df.columns[1]: "your value" }, inplace = True)

The following ways work.

// The old way of using ParameterizedThreadStart. This requires a
// method which takes ONE object as the parameter so you need to
// encapsulate the parameters inside one object.
Thread t = new Thread(new ParameterizedThreadStart(StartupA));
t.Start(new MyThreadParams(path, port));

// You can also use an anonymous delegate to do this.
Thread t2 = new Thread(delegate()
{
    StartupB(port, path);
});
t2.Start();

// Or lambda expressions if you are using C# 3.0
Thread t3 = new Thread(() => StartupB(port, path));
t3.Start();

The Startup methods have following signature for these examples.

public void StartupA(object parameters);

public void StartupB(int port, string path);

The point is that the first line of your codes is not what you expected.

You should use:

val map = scala.collection.mutable.Map[A,B]()

You then have multiple equivalent alternatives to add items:

scala> val map = scala.collection.mutable.Map[String,String]()
map: scala.collection.mutable.Map[String,String] = Map()


scala> map("k1") = "v1"

scala> map
res1: scala.collection.mutable.Map[String,String] = Map((k1,v1))


scala> map += "k2" -> "v2"
res2: map.type = Map((k1,v1), (k2,v2))


scala> map.put("k3", "v3")
res3: Option[String] = None

scala> map
res4: scala.collection.mutable.Map[String,String] = Map((k3,v3), (k1,v1), (k2,v2))

And starting Scala 2.13:

scala> map.addOne("k4" -> "v4")
res5: map.type = HashMap(k1 -> v1, k2 -> v2, k3 -> v3, k4 -> v4)

<input type="text" autocomplete="off"/>

Should work. Alternatively, use:

<form autocomplete="off" … >

for the entire form (see this related question).

Using boost:

#include <boost/algorithm/hex.hpp>

std::string s("tralalalala");
std::string result;
boost::algorithm::hex(s.begin(), s.end(), std::back_inserter(result));

I know this is a two year old question, but this is a quick answer for those searching for a 'how to'.

If you don't want to have to put quotes around anything you can simply write a block of text to a file, and escape variables you want to export as text (for instance for use in a script) and not escape one's you want to export as the value of the variable.

#!/bin/bash

FILE_NAME="test.txt"
VAR_EXAMPLE="\"string\""

cat > ${FILE_NAME} << EOF
\${VAR_EXAMPLE}=${VAR_EXAMPLE} in ${FILE_NAME}  
EOF

Will write "${VAR_EXAMPLE}="string" in test.txt" into test.txt

This can also be used to output blocks of text to the console with the same rules by omitting the file name

#!/bin/bash

VAR_EXAMPLE="\"string\""

cat << EOF
\${VAR_EXAMPLE}=${VAR_EXAMPLE} to console 
EOF

Will output "${VAR_EXAMPLE}="string" to console" to the console

In short, yes.

Suppose we are on a 32-bit machine.

If it is little endian, the x in the memory will be something like:

       higher memory
          ----->
    +----+----+----+----+
    |0x01|0x00|0x00|0x00|
    +----+----+----+----+
    A
    |
   &x

so (char*)(&x) == 1, and *y+48 == '1'.

If it is big endian, it will be:

    +----+----+----+----+
    |0x00|0x00|0x00|0x01|
    +----+----+----+----+
    A
    |
   &x

so this one will be '0'.

}

In the Windows command prompt you can disable tab completion, by launching it thusly:

cmd.exe /f:off

Then the tab character will be echoed to the screen and work as you expect. Or you can disable the tab completion character, or modify what character is used for tab completion by modifying the registry.

The cmd.exe help page explains it:

You can enable or disable file name completion for a particular invocation of CMD.EXE with the /F:ON or /F:OFF switch. You can enable or disable completion for all invocations of CMD.EXE on a machine and/or user logon session by setting either or both of the following REG_DWORD values in the registry using REGEDIT.EXE:

HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\CompletionChar
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\PathCompletionChar

    and/or

HKEY_CURRENT_USER\Software\Microsoft\Command Processor\CompletionChar
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\PathCompletionChar

with the hex value of a control character to use for a particular function (e.g. 0x4 is Ctrl-D and 0x6 is Ctrl-F). The user specific settings take precedence over the machine settings. The command line switches take precedence over the registry settings.

If completion is enabled with the /F:ON switch, the two control characters used are Ctrl-D for directory name completion and Ctrl-F for file name completion. To disable a particular completion character in the registry, use the value for space (0x20) as it is not a valid control character.

If there is only 1 occurrence, the answer of ivanovic is the best way I guess. But if there are many occurrences, you should use regexp:

\[(.*?)\] this is your pattern. And in each group(1) will get you your string.

Pattern p = Pattern.compile("\\[(.*?)\\]");
Matcher m = p.matcher(input);
while(m.find())
{
    m.group(1); //is your string. do what you want
}

Have you noticed that you don't get the error if you run

python ./script.py

instead of

python script.py

This is because sys.argv[0] will read ./script.py in the former case, which gives os.path.dirname something to work with. When you don't specify a path, sys.argv[0] reads simply script.py, and os.path.dirname cannot determine a path.

In my case opening 'Help' >> "Install New Software" had no entries for any URLs (previous url's were not there) - so I Manually added 'em. And updated ... and Voilaaaa !! Above posts have been very helpful in resolving this issue for me.

An ioctl, which means "input-output control" is a kind of device-specific system call. There are only a few system calls in Linux (300-400), which are not enough to express all the unique functions devices may have. So a driver can define an ioctl which allows a userspace application to send it orders. However, ioctls are not very flexible and tend to get a bit cluttered (dozens of "magic numbers" which just work... or not), and can also be insecure, as you pass a buffer into the kernel - bad handling can break things easily.

An alternative is the sysfs interface, where you set up a file under /sys/ and read/write that to get information from and to the driver. An example of how to set this up:

static ssize_t mydrvr_version_show(struct device *dev,
        struct device_attribute *attr, char *buf)
{
    return sprintf(buf, "%s\n", DRIVER_RELEASE);
}

static DEVICE_ATTR(version, S_IRUGO, mydrvr_version_show, NULL);

And during driver setup:

device_create_file(dev, &dev_attr_version);

You would then have a file for your device in /sys/, for example, /sys/block/myblk/version for a block driver.

Another method for heavier use is netlink, which is an IPC (inter-process communication) method to talk to your driver over a BSD socket interface. This is used, for example, by the WiFi drivers. You then communicate with it from userspace using the libnl or libnl3 libraries.

To avoid placing HTML tags in the title attribute, another solution is to use markdown. For instance, you could use [br] to represent a line break, then perform a simple replace in the content function.

In title attribute:

"Sample Line 1[br][br]Sample Line 2"

In your content function:

content: function () {
    return $(this).attr('title').replace(/\[br\]/g,"<br />");
}

loggingOutInterceptor.setPrettyLogging(true);
factory.getInInterceptors().add(loggingInInterceptor);
factory.getOutInterceptors().add(loggingOutInterceptor);

Math.max() is actually as3 code compiled to AVM2 opcodes, and as such is not more "native" than any other as3 code. As a consequence, it is not necessarily the fastest implementation.

Actually, given that it works on Array type, it is slower than carefully written code usign Vector:

I did a quick benchmark comparison of several naive Vector and Array implementations of Math.max, using gskinner's PerformanceTest (Vector and Array being filled with identical random Numbers). The fastest Vector implementation appeared to be more than 3x faster than Math.max with recent AIR SDK/release player (flash player WIN 14,0,0,122 RELEASE, compiled with AIR SDK 14):

average 3.5 ms for 1,000,000 values, compared to Math.max() average of 11ms :

function max(values:Vector.<Number>):Number
{
    var max:Number = Number.MIN_VALUE;
    var length:uint = values.length;
    for (var i:uint = 0; i < length ; ++i)
        if (values[i] > max)
            max = values[i];
    return max;
}

Conclusion is that if you are concerned by performance, you should use Vector over Array anywhere you can in the first place, and not always rely on default implementations, especially when they force the use of Array

PS:same implementation with a for each() loop is 12x slower ...!

The explanation for how it works:

JUnit wraps your test method in a Statement object so statement and Execute() runs your test. Then instead of calling statement.Execute() directly to run your test, JUnit passes the Statement to a TestRule with the @Rule annotation. The TestRule's "apply" function returns a new Statement given the Statement with your test. The new Statement's Execute() method can call the test Statement's execute method (or not, or call it multiple times), and do whatever it wants before and after.

Now, JUnit has a new Statement that does more than just run the test, and it can again pass that to any more rules before finally calling Execute.

On Arch Linux run the following:

sudo pacman -S base-devel

Adding usefulness to @Dan's example, I had the need to find the next midday or midnight.

var d = new Date();
if(d.getHours() < 12) {
   d.setHours(12,0,0,0); // next midnight/midday is midday
} else {
   d.setHours(24,0,0,0); // next midnight/midday is midnight
}

This allowed me to set a frequency cap for an event, only allowing it to happen once in the morning and once in the afternoon for any visitor to my site. The date captured was used to set the expiration of the cookie.

The above error in my case was actually due to the wrong username and password. Solving the issue: 1. Go to the line DriverManager.getConnection("jdbc:mysql://localhost:3306/?useSSL=false", "username", "password"); The fields username and password might be wrong. Enter the username and password which you use to start your mysql client. The username is generally root and password is the string which you enter when a screen similar to this appears Startup screen of mysql

Note: The portname 3306 might be different in your case.

If you use Linux or use Cygwin or MinGW in windows you can use bash-like solutions like the following. Contrasting with other similar ones presented here, this one takes into account file name spaces:

svn status| grep ^? | while read line ; do  svn add "`echo $line|cut --complement -c 1,2`" ;done

Yes. I have checked so many books and other blogs... The conclusion is, there isn't any system variable for the loop counter. We have to make our own counter. Correct me if I'm wrong.

You can add and retrieve a numpy array from dataframe using this:

import numpy as np
import pandas as pd

df = pd.DataFrame({'b':range(10)}) # target dataframe
a = np.random.normal(size=(10,2)) # numpy array
df['a']=a.tolist() # save array
np.array(df['a'].tolist()) # retrieve array

This builds on the previous answer that confused me because of the sparse part and this works well for a non-sparse numpy arrray.

For SQL Server

select *
from YourTable
where DateCol between getdate() and dateadd(d, 90, getdate())

In your example, Java is performing integer arithmetic, rounding off the result of the division.

Based on your question, you would like to perform floating-point arithmetic. To do so, at least one of your terms must be specified as (or converted to) floating-point:

Specifying floating point:

3.0/2
3.0/2.0
3/2.0

Converting to floating point:

int a = 2;
int b = 3;
float q = ((float)a)/b;

or

double q = ((double)a)/b;

(See Java Traps: double and Java Floating-Point Number Intricacies for discussions on float and double)

delay() will not do the job. The problem with delay() is it's part of the animation system, and only applies to animation queues.

What if you want to wait before executing something outside of animation??

Use this:

window.setTimeout(function(){
                 // do whatever you want to do     
                  }, 600);

What happens?: In this scenario it waits 600 miliseconds before executing the code specified within the curly braces.

This helped me a great deal once I figured it out and hope it will help you as well!

IMPORTANT NOTICE: 'window.setTimeout' happens asynchronously. Keep that in mind when writing your code!

First enable mod_headers on your server, then you can use header directive in both Apache conf and .htaccess.

1. enable mod_headers

• a2enmod headers

2. configure header in .htaccess file

• Header add Access-Control-Allow-Origin "*"
• Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
• Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"

Yet another solution using the previous suggestions, but with the "correct" parse error from argparse:

def str2bool(v):
    if isinstance(v, bool):
       return v
    if v.lower() in ('yes', 'true', 't', 'y', '1'):
        return True
    elif v.lower() in ('no', 'false', 'f', 'n', '0'):
        return False
    else:
        raise argparse.ArgumentTypeError('Boolean value expected.')

This is very useful to make switches with default values; for instance

parser.add_argument("--nice", type=str2bool, nargs='?',
                        const=True, default=False,
                        help="Activate nice mode.")

allows me to use:

script --nice
script --nice <bool>

and still use a default value (specific to the user settings). One (indirectly related) downside with that approach is that the 'nargs' might catch a positional argument -- see this related question and this argparse bug report.

Use -H or --header.

One important thing to mention as well is the security improvement that comes with the package-lock file. Since it keeps all the hashes of the packages if someone would tamper with the public npm registry and change the source code of a package without even changing the version of the package itself it would be detected by the package-lock file.

This is not an issue, this is a design of Android. See here:

You should design each fragment as a modular and reusable activity component. That is, because each fragment defines its own layout and its own behavior with its own lifecycle callbacks, you can include one fragment in multiple activities, so you should design for reuse and avoid directly manipulating one fragment from another fragment.

A possible workaround would be to do something like this in your MainActivity:

Fragment someFragment;    

...onCreate etc instantiating your fragments

public void myClickMethod(View v){
    someFragment.myClickMethod(v);
}

and then in your Fragment class:

public void myClickMethod(View v){
    switch(v.getid()){
       // Your code here
    }
 } 

Other answers have suggested using TryParse, which might fit your needs, but the safest way to provide the functionality of the IsNumeric function is to reference the VB library and use the IsNumeric function.

IsNumeric is more flexible than TryParse. For example, IsNumeric returns true for the string "$100", while the TryParse methods all return false.

To use IsNumeric in C#, add a reference to Microsoft.VisualBasic.dll. The function is a static method of the Microsoft.VisualBasic.Information class, so assuming you have using Microsoft.VisualBasic;, you can do this:

if (Information.IsNumeric(txtMyText.Text.Trim())) //...

This is a great spot for a reduce

var uniqueArray = o.DATA.reduce(function (a, d) {
       if (a.indexOf(d.name) === -1) {
         a.push(d.name);
       }
       return a;
    }, []);

Follow the below steps for push the local repo into Master branchenter code here

$git status

you can specify fields like this:

LOAD XML LOCAL INFILE '/pathtofile/file.xml' 
INTO TABLE my_tablename(personal_number, firstname, ...); 

You can add this to your _Layout.cshtml:

@using MyProj.ViewModels;
...
    @if (TempData["UserMessage"] != null)
    {
        var message = (MessageViewModel)TempData["UserMessage"];
        <div class="alert @message.CssClassName" role="alert">
            <button type="button" class="close" data-dismiss="alert" aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
            <strong>@message.Title</strong>
            @message.Message
        </div>
    }

Then if you want to throw an error message in your controller:

    TempData["UserMessage"] = new MessageViewModel() { CssClassName = "alert-danger  alert-dismissible", Title = "Error", Message = "This is an error message" };

MessageViewModel.cs:

public class MessageViewModel
    {
        public string CssClassName { get; set; }
        public string Title { get; set; }
        public string Message { get; set; }
    }

Note: Using Bootstrap 4 classes.

another alternative, just in case you want to have a shell script which creates the database if it does not exist and otherwise just keeps it as it is:

psql -U postgres -tc "SELECT 1 FROM pg_database WHERE datname = 'my_db'" | grep -q 1 || psql -U postgres -c "CREATE DATABASE my_db"

I found this to be helpful in devops provisioning scripts, which you might want to run multiple times over the same instance.

For those of you who would like an explanation:

-c = run command in database session, command is given in string
-t = skip header and footer
-q = silent mode for grep 
|| = logical OR, if grep fails to find match run the subsequent command

Enums are just classes in disguise, so for the most part, anything you can do with a class you can do with an enum.

I cannot think of a reason that an enum should not be able to implement an interface, at the same time I cannot think of a good reason for them to either.

I would say once you start adding thing like interfaces, or method to an enum you should really consider making it a class instead. Of course I am sure there are valid cases for doing non-traditional enum things, and since the limit would be an artificial one, I am in favour of letting people do what they want there.

A helper method would alleviate this extra overhead, and give you the same jQuery feel.

function Deferred() {
    let resolve;
    let reject;
    const promise = new Promise((res, rej) => {
        resolve = res;
        reject = rej;
    });
    return { promise, resolve, reject };
}

Usage would be

const { promise, resolve, reject } = Deferred();
displayConfirmationDialog({
    confirm: resolve,
    cancel: reject
});
return promise;

Which is similar to jQuery

const dfd = $.Deferred();
displayConfirmationDialog({
    confirm: dfd.resolve,
    cancel: dfd.reject
});
return dfd.promise();

Although, in a use case this simple, native syntax is fine

return new Promise((resolve, reject) => {
    displayConfirmationDialog({
        confirm: resolve,
        cancel: reject
    });
});

as Harry Joy points out, set the image as the div's background and then, if you only have one line of text you can set the line-height of the text to be the same as the div height and this will place your text in the center of the div.

If you have more than one line you'll want to set the display to be table-cell and vertical-alignment to middle.

I'm trying for the simplest and most self-explanatory method here:

git status | grep "On branch" | cut -c 11-

I haven't been able to get good results from ImageMagick in this instance, but Inkscape does a nice job of scaling an SVG on Linux and Windows:

inkscape -z -w 1024 -h 1024 input.svg -e output.png

Note that you can omit one of the width/height parameters to have the other parameter scaled automatically based on the input image dimensions.

Edit (May 2020): Inkscape 1.0 users, please note that the command line arguments have changed:

inkscape -w 1024 -h 1024 input.svg -o output.png

Here's the result of scaling a 16x16 SVG to a 200x200 PNG using this command:

Just for reference, my Inkscape version (on Ubuntu 12.04) is:

Inkscape 0.48.3.1 r9886 (Mar 29 2012)

and on Windows 7, it is:

Inkscape 0.48.4 r9939 (Dec 17 2012)

Every time you call itr2.next() you are getting a distinct value. Not the same value. You should only call this once in the loop.

        System.out.println("Key: "+v+" ,value: "+m.get(v));
    }

UPDATE 7/3/2014: As of now, jquery-latest.js is no longer being updated. From the jQuery blog:

We know that http://code.jquery.com/jquery-latest.js is abused because of the CDN statistics showing it’s the most popular file. That wouldn’t be the case if it was only being used by developers to make a local copy.

We have decided to stop updating this file, as well as the minified copy, keeping both files at version 1.11.1 forever.

The Google CDN team has joined us in this effort to prevent inadvertent web breakage and no longer updates the file at http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js. That file will stay locked at version 1.11.1 as well.

The following, now moot, answer is preserved here for historical reasons.

Don't do this. Seriously, don't.

Linking to major versions of jQuery does work, but it's a bad idea -- whole new features get added and deprecated with each decimal update. If you update jQuery automatically without testing your code COMPLETELY, you risk an unexpected surprise if the API for some critical method has changed.

Here's what you should be doing: write your code using the latest version of jQuery. Test it, debug it, publish it when it's ready for production.

Then, when a new version of jQuery rolls out, ask yourself: Do I need this new version in my code? For instance, is there some critical browser compatibility that didn't exist before, or will it speed up my code in most browsers?

If the answer is "no", don't bother updating your code to the latest jQuery version. Doing so might even add NEW errors to your code which didn't exist before. No responsible developer would automatically include new code from another site without testing it thoroughly.

There's simply no good reason to ALWAYS be using the latest version of jQuery. The old versions are still available on the CDNs, and if they work for your purposes, then why bother replacing them?

A secondary, but possibly more important, issue is caching. Many people link to jQuery on a CDN because many other sites do, and your users have a good chance of having that version already cached.

The problem is, caching only works if you provide a full version number. If you provide a partial version number, far-future caching doesn't happen -- because if it did, some users would get different minor versions of jQuery from the same URL. (Say that the link to 1.7 points to 1.7.1 one day and 1.7.2 the next day. How will the browser make sure it's getting the latest version today? Answer: no caching.)

In fact here's a breakdown of several options and their expiration settings...

http://code.jquery.com/jquery-latest.min.js (no cache)

http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js (1 hour)

http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js (1 hour)

http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js (1 year)

So, by linking to jQuery this way, you're actually eliminating one of the major reasons to use a CDN in the first place.

http://code.jquery.com/jquery-latest.min.js may not always give you the version you expect, either. As of this writing, it links to the latest version of jQuery 1.x, even though jQuery 2.x has been released as well. This is because jQuery 1.x is compatible with older browsers including IE 6/7/8, and jQuery 2.x is not. If you want the latest version of jQuery 2.x, then (for now) you need to specify that explicitly.

The two versions have the same API, so there is no perceptual difference for compatible browsers. However, jQuery 1.x is a larger download than 2.x.

If you don't want to use a FormData object (e.g. your API takes specific content-type signatures and multipart/formdata isn't one of them) then you can do this instead:

uploadFile: function (event) {
    const file = event.target.files[0]
    axios.post('upload_file', file, {
        headers: {
          'Content-Type': file.type
        }
    })
}

To address the question more generally...

Keep in mind that using synchronized on methods is really just shorthand (assume class is SomeClass):

synchronized static void foo() {
    ...
}

is the same as

static void foo() {
    synchronized(SomeClass.class) {
        ...
    }
}

and

synchronized void foo() {
    ...
}

is the same as

void foo() {
    synchronized(this) {
        ...
    }
}

You can use any object as the lock. If you want to lock subsets of static methods, you can

class SomeClass {
    private static final Object LOCK_1 = new Object() {};
    private static final Object LOCK_2 = new Object() {};
    static void foo() {
        synchronized(LOCK_1) {...}
    }
    static void fee() {
        synchronized(LOCK_1) {...}
    }
    static void fie() {
        synchronized(LOCK_2) {...}
    }
    static void fo() {
        synchronized(LOCK_2) {...}
    }
}

(for non-static methods, you would want to make the locks be non-static fields)

This worked for me:

@Override
protected void onStart() {
    super.onStart();
    mySpinner.setSelection(position);
}

It's similar to @sberezin's solution but calling setSelection() in onStart().

You can use a conditional expression:

x if x is not None else some_value

Example:

In [22]: x = None

In [23]: print x if x is not None else "foo"
foo

In [24]: x = "bar"

In [25]: print x if x is not None else "foo"
bar

You're almost there. Although I agree with @Alex Young answer about using props for that, you simply need a reference to the instance before trying to spy on the method.

describe('my sweet test', () => {
 it('clicks it', () => {
    const app = shallow(<App />)
    const instance = app.instance()
    const spy = jest.spyOn(instance, 'myClickFunc')

    instance.forceUpdate();    

    const p = app.find('.App-intro')
    p.simulate('click')
    expect(spy).toHaveBeenCalled()
 })
})

Atlassian's Stash (Now called BitBucket Server) is getting there to being a good Github Enterprise alternative. I'm a bit of a JIRA whore so I like the integrations you have with that.

I found an easier way to do it and it works perfectly even if you don't know the path where the chrome is located.

First of all, you have to paste this code in the top of the module.

Option Explicit
Private pWebAddress As String
Public Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
(ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, _
ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

After that you have to create this two modules:

Sub LoadExplorer()
    LoadFile "Chrome.exe" ' Here you are executing the chrome. exe
End Sub

Sub LoadFile(FileName As String)
    ShellExecute 0, "Open", FileName, "http://test.123", "", 1 ' You can change the URL.
End Sub

With this you will be able (if you want) to set a variable for the url or just leave it like hardcode.

Ps: It works perfectly for others browsers just changing "Chrome.exe" to opera, bing, etc.

It can also mean that the server is completely inaccessible - I was getting this when trying to hit a server that was offline

My client was configured to connect to localhost:3000, but no server was running on that port.

if you are using event.preventDefault() in your script then comment it out because IE doesn't likes it.

2017 Update - since WooCommerce 3:

global $product;
$id = $product->get_id();

Woocommerce doesn't like you accessing those variables directly. This will get rid of any warnings from woocommerce if your wp_debug is true.

if you don't need variable, you can define text in
translations/messages.en.yaml :
CiteExampleHtmlCode: "<b> my static text </b>"

then use it with twig:
templates/about/index.html.twig
… {{ 'CiteExampleHtmlCode' }}
or if you need multilangages like me:
… {{ 'CiteExampleHtmlCode' | trans }}

Let's have a look of https://symfony.com/doc/current/translation.html for more information about translations use.

Add this to your project file:

CONFIG += console

Unless PHP has a builtin for that, you won't be able to do it in less than O(n) - enumerating over all the keys and checking for integer type. In fact, you also want to make sure there are no holes, so your algorithm might look like:

for i in 0 to len(your_array):
    if not defined(your-array[i]):
        # this is not an array array, it's an associative array :)

But why bother? Just assume the array is of the type you expect. If it isn't, it will just blow up in your face - that's dynamic programming for you! Test your code and all will be well...

You can simply do it like this with an object literal:

function makeGamePlayer(name,totalScore,gamesPlayed) {
    return {
        name: name,
        totalscore: totalScore,
        gamesPlayed: gamesPlayed
    };
}

Try this configuration. It worked for me:

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <warSourceDirectory>mywebRoot</warSourceDirectory>

It depends on what you are trying to do.

file, err := os.Open("file.txt")
fmt.print(file)

The reason it outputs &{0xc082016240}, is because you are printing the pointer value of a file-descriptor (*os.File), not file-content. To obtain file-content, you may READ from a file-descriptor.

To read all file content(in bytes) to memory, ioutil.ReadAll

package main

import (
    "fmt"
    "io/ioutil"
    "os"
    "log"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


  b, err := ioutil.ReadAll(file)
  fmt.Print(b)
}

But sometimes, if the file size is big, it might be more memory-efficient to just read in chunks: buffer-size, hence you could use the implementation of io.Reader.Read from *os.File

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


    buf := make([]byte, 32*1024) // define your buffer size here.

    for {
        n, err := file.Read(buf)

        if n > 0 {
            fmt.Print(buf[:n]) // your read buffer.
        }

        if err == io.EOF {
            break
        }
        if err != nil {
            log.Printf("read %d bytes: %v", n, err)
            break
        }
    }

}

Otherwise, you could also use the standard util package: bufio, try Scanner. A Scanner reads your file in tokens: separator.

By default, scanner advances the token by newline (of course you can customise how scanner should tokenise your file, learn from here the bufio test).

package main

import (
    "fmt"
    "os"
    "log"
    "bufio"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()

    scanner := bufio.NewScanner(file)

    for scanner.Scan() {             // internally, it advances token based on sperator
        fmt.Println(scanner.Text())  // token in unicode-char
        fmt.Println(scanner.Bytes()) // token in bytes

    }
}

Lastly, I would also like to reference you to this awesome site: go-lang file cheatsheet. It encompassed pretty much everything related to working with files in go-lang, hope you'll find it useful.

Not sure what you are asking, but... Class.forname, maybe?

The List<T> has a constructor that accepts an IEnumerable<T>:

List<string> listOfNames = new List<string>(names.Split(','));

The other answers cover how to do std dev in python sufficiently, but no one explains how to do the bizarre traversal you've described.

I'm going to assume A-Z is the entire population. If not see Ome's answer on how to inference from a sample.

So to get the standard deviation/mean of the first digit of every list you would need something like this:

#standard deviation
numpy.std([A_rank[0], B_rank[0], C_rank[0], ..., Z_rank[0]])

#mean
numpy.mean([A_rank[0], B_rank[0], C_rank[0], ..., Z_rank[0]])

To shorten the code and generalize this to any nth digit use the following function I generated for you:

def getAllNthRanks(n):
    return [A_rank[n], B_rank[n], C_rank[n], D_rank[n], E_rank[n], F_rank[n], G_rank[n], H_rank[n], I_rank[n], J_rank[n], K_rank[n], L_rank[n], M_rank[n], N_rank[n], O_rank[n], P_rank[n], Q_rank[n], R_rank[n], S_rank[n], T_rank[n], U_rank[n], V_rank[n], W_rank[n], X_rank[n], Y_rank[n], Z_rank[n]] 

Now you can simply get the stdd and mean of all the nth places from A-Z like this:

#standard deviation
numpy.std(getAllNthRanks(n))

#mean
numpy.mean(getAllNthRanks(n))
