Joda-Time

Here is the same kind of code but using the third-party library Joda-Time 2.3.

In real life, I would specify a time zone, as relying on default zone is usually a bad practice. But omitted here for simplicity of example.

org.joda.time.DateTime now = new DateTime();
org.joda.time.format.DateTimeFormatter formatter = DateTimeFormat.forPattern( "MM/dd/yyyy h:mm:ss a" );
String nowAsString = formatter.print( now );

System.out.println( "nowAsString: " + nowAsString );

When run…

nowAsString: 11/28/2013 11:28:15 PM

I understand the original post is for Oracle 10 but this is for reference by anyone else who finds it via Google.

Under Oracle 12c, I found that that my registry$history is empty. This works instead:

select * from registry$sqlpatch;

The boost::dll::program_location function is one of the best cross platform methods of getting the path of the running executable that I know of. The DLL library was added to Boost in version 1.61.0.

The following is my solution. I have tested it on Windows, Mac OS X, Solaris, Free BSD, and GNU/Linux.

It requires Boost 1.55.0 or greater. It uses the Boost.Filesystem library directly and the Boost.Locale library and Boost.System library indirectly.

I have a complete project, including a test application and CMake build files available at SnKOpen - /cpp/executable_path/trunk. This version is more complete than the version I provided here. It is also supports more platforms.

I have tested the application on all supported operating systems in the following four scenarios.

1. Relative path, executable in current directory: i.e. ./executable_path_test
2. Relative path, executable in another directory: i.e. ./build/executable_path_test
3. Full path: i.e. /some/dir/executable_path_test
4. Executable in path, file name only: i.e. executable_path_test

In all four scenarios, both the executable_path and executable_path_fallback functions work and return the same results.

Notes

This is an updated answer to this question. I updated the answer to take into consideration user comments and suggestions. I also added a link to a project in my SVN Repository.

I use this method as a wrapper so that I can send parameters. Also using the variables in the top of the method allows it to be minimized at a higher ratio and allows for some code reuse if making multiple similar calls.

function InfoByDate(sDate, eDate){
    var divToBeWorkedOn = "#AjaxPlaceHolder";
    var webMethod = "http://MyWebService/Web.asmx/GetInfoByDates";
    var parameters = "{'sDate':'" + sDate + "','eDate':'" + eDate + "'}";

    $.ajax({
        type: "POST",
        url: webMethod,
        data: parameters,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(msg) {
            $(divToBeWorkedOn).html(msg.d);
        },
        error: function(e){
            $(divToBeWorkedOn).html("Unavailable");
        }
    });
}

I hope that helps.

Please note that this requires the 3.5 framework to expose JSON webmethods that can be consumed in this manner.

i don't know about converting into a byte array, but it's easy to convert it into a string:

import base64

with open("t.png", "rb") as imageFile:
    str = base64.b64encode(imageFile.read())
    print str

Here is what I would recommend.

It should conform to C89, and be completely portable. In particular, it works also on pipes and sockets on POSIXy systems.

The idea is that we read the input in large-ish chunks (READALL_CHUNK), dynamically reallocating the buffer as we need it. We only use realloc(), fread(), ferror(), and free():

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

/* Size of each input chunk to be
   read and allocate for. */
#ifndef  READALL_CHUNK
#define  READALL_CHUNK  262144
#endif

#define  READALL_OK          0  /* Success */
#define  READALL_INVALID    -1  /* Invalid parameters */
#define  READALL_ERROR      -2  /* Stream error */
#define  READALL_TOOMUCH    -3  /* Too much input */
#define  READALL_NOMEM      -4  /* Out of memory */

/* This function returns one of the READALL_ constants above.
   If the return value is zero == READALL_OK, then:
     (*dataptr) points to a dynamically allocated buffer, with
     (*sizeptr) chars read from the file.
     The buffer is allocated for one extra char, which is NUL,
     and automatically appended after the data.
   Initial values of (*dataptr) and (*sizeptr) are ignored.
*/
int readall(FILE *in, char **dataptr, size_t *sizeptr)
{
    char  *data = NULL, *temp;
    size_t size = 0;
    size_t used = 0;
    size_t n;

    /* None of the parameters can be NULL. */
    if (in == NULL || dataptr == NULL || sizeptr == NULL)
        return READALL_INVALID;

    /* A read error already occurred? */
    if (ferror(in))
        return READALL_ERROR;

    while (1) {

        if (used + READALL_CHUNK + 1 > size) {
            size = used + READALL_CHUNK + 1;

            /* Overflow check. Some ANSI C compilers
               may optimize this away, though. */
            if (size <= used) {
                free(data);
                return READALL_TOOMUCH;
            }

            temp = realloc(data, size);
            if (temp == NULL) {
                free(data);
                return READALL_NOMEM;
            }
            data = temp;
        }

        n = fread(data + used, 1, READALL_CHUNK, in);
        if (n == 0)
            break;

        used += n;
    }

    if (ferror(in)) {
        free(data);
        return READALL_ERROR;
    }

    temp = realloc(data, used + 1);
    if (temp == NULL) {
        free(data);
        return READALL_NOMEM;
    }
    data = temp;
    data[used] = '\0';

    *dataptr = data;
    *sizeptr = used;

    return READALL_OK;
}

Above, I've used a constant chunk size, READALL_CHUNK == 262144 (256*1024). This means that in the worst case, up to 262145 chars are wasted (allocated but not used), but only temporarily. At the end, the function reallocates the buffer to the optimal size. Also, this means that we do four reallocations per megabyte of data read.

The 262144-byte default in the code above is a conservative value; it works well for even old minilaptops and Raspberry Pis and most embedded devices with at least a few megabytes of RAM available for the process. Yet, it is not so small that it slows down the operation (due to many read calls, and many buffer reallocations) on most systems.

For desktop machines at this time (2017), I recommend a much larger READALL_CHUNK, perhaps #define READALL_CHUNK 2097152 (2 MiB).

Because the definition of READALL_CHUNK is guarded (i.e., it is defined only if it is at that point in the code still undefined), you can override the default value at compile time, by using (in most C compilers) -DREADALL_CHUNK=2097152 command-line option -- but do check your compiler options for defining a preprocessor macro using command-line options.

In my case the issue revealed to be chrome blocking the CORS request from localhost:4200 to facebook api website. Running Chrome with this setting: "YOUR_PATH_TO_CHROME\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="c:/chrome worked like a charm while developing. Even with no localhost added to facebook app's settings.

Python 2:

>>> theArray = [['a','b','c'],['d','e','f'],['g','h','i']]
>>> zip(*theArray)
[('a', 'd', 'g'), ('b', 'e', 'h'), ('c', 'f', 'i')]

Python 3:

>>> [*zip(*theArray)]
[('a', 'd', 'g'), ('b', 'e', 'h'), ('c', 'f', 'i')]

The ASCII table contains 128 codes, with a total of 95 printable characters, of which only 52 characters are letters:

• [0-127] ASCII codes
  • [32-126] printable characters
    • [48-57] digits [0-9]
    • [65-90] uppercase letters [A-Z]
    • [97-122] lowercase letters [a-z]

You can use String.codePoints method to get a stream over int values of characters of this string and filter out non-ASCII characters:

String str1 = "A função, Ãugent";

String str2 = str1.codePoints()
        .filter(ch -> ch < 128)
        .mapToObj(Character::toString)
        .collect(Collectors.joining());

System.out.println(str2); // A funo, ugent

Or you can explicitly specify character ranges. For example filter out everything except letters:

String str3 = str1.codePoints()
        .filter(ch -> ch >= 'A' && ch <= 'Z'
                || ch >= 'a' && ch <= 'z')
        .mapToObj(Character::toString)
        .collect(Collectors.joining());

System.out.println(str3); // Afunougent

What makes jQuery easy to use is that you don't have to apply attributes to each element. The jQuery object contains an array of elements, and the methods of the jQuery object applies the same attributes to all the elements in the array.

There is also a shorter form for $(document).ready(function(){...}) in $(function(){...}).

So, this is all you need:

$(function(){
  $('div.easy_editor').css('border','9px solid red');
});

If you want the code to work for any element with that class, you can just specify the class in the selector without the tag name:

$(function(){
  $('.easy_editor').css('border','9px solid red');
});

The git cherry-pick <commit> command allows you to take a single commit (from whatever branch) and, essentially, rebase it in your working branch.

Chapter 5 of the Pro Git book explains it better than I can, complete with diagrams and such. (The chapter on Rebasing is also good reading.)

Lastly, there are some good comments on the cherry-picking vs merging vs rebasing in another SO question.

I had the same problem because I changed the user from myself to someone else:

su

For some reason, after did the normal compiling I was not able to execute it (the same error message). Directly ssh to the other user account works.

All nice solutions, borrowing and improvising for special case -> If you want to add a label near the arrowhead:

    arr = [2,3]
    txt = “Vector X”
    ax.annotate(txt, arr)
    ax.arrow(0, 0, *arr, head_width=0.05, head_length=0.1)

I am developing an app to version 2.2, API version would in the 8th ... had the same error and the error told me it was to google maps API, all we did was change my ADV for my project API 2.2 and also for the API.

This worked for me and found the library API needed.

I'm probably late but this worked for me:

1. Open your build.xml file located in your project's directory.
2. Copy and Paste the following code in the main project tag : <target name="build" />

This has a good general description: https://gephi.wordpress.com/tag/maven/

Let me make a few statement that can put the difference in focus:

1. We migrated our code base from Ant to Maven

2. All 3rd party librairies have been uploaded to Nexus. Maven is using Nexus as a source for libraries.

3. Basic functionalities of a repository manager like Sonatype are:

   • Managing project dependencies,
   • Artifacts & Metadata,
   • Proxying external repositories
   • and deployment of packaged binaries and JARs to share those artifacts with other developers and end-users.

Let's say we need to use the class Classname that is contained in the jar file org.example.jar

And your source is in the file mysource.java Like this:

import org.example.Classname;

public class mysource {
    public static void main(String[] argv) {
    ......
   }
}

First, as you see, in your code you have to import the classes. To do that you need import org.example.Classname;

Second, when you compile the source, you have to reference the jar file.

Please note the difference in using : and ; while compiling

• If you are under a unix like operating system:

  javac -cp '.:org.example.jar' mysource.java
  

• If you are under windows:

  javac -cp .;org.example.jar mysource.java
  

After this, you obtain the bytecode file mysource.class

Now you can run this :

• If you are under a unix like operating system:

  java -cp '.:org.example.jar' mysource
  

• If you are under windows:

  java -cp .;org.example.jar mysource
  

-(void) addBlurEffectOverImageView:(UIImageView *) _imageView
{
    UIVisualEffect *blurEffect;
    blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];

    UIVisualEffectView *visualEffectView;
    visualEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];

    visualEffectView.frame = _imageView.bounds;
    [_imageView addSubview:visualEffectView];
}

You can do this:

/* Clearfix for the menu */
.ui-menu:after {
    content: ".";
    display: block;
    clear: both;
    visibility: hidden;
    line-height: 0;
    height: 0;
}

and also set:

.ui-menu .ui-menu-item {
    display: inline-block;
    float: left;
    margin: 0;
    padding: 0;
    width: auto;
}

Here is how I would do it if working with a large number of "to remove" values that would take a long time to manually remove.

• -Put Original List in Column A -Put To Remove list in Column B -Select both columns, then "Conditional Formatting"
  -Select "Hightlight Cells Rules" --> "Duplicate Values"
  -The duplicates should be hightlighted in both columns
  -Then select Column A and then "Sort & Filter" ---> "Custom Sort"
  -In the dialog box that appears, select the middle option "Sort On" and pick "Cell Color"
  -Then select the next option "Sort Order" and choose "No Cell Color" "On bottom"
  -All the highlighted cells should be at the top of the list. -Select all the highlighted cells by scrolling down the list, then click delete.

• UPDATED FOR CATALINA & SAFARI 13 (early 2020 Update) *

PLEASE PLEASE -- If you are having trouble, and really want to get help or help others by posting a comment about it, Post Your Browser and Device (MacBook/IPad/etc... with both browser and OS version numbers!)

Claiming none of these work is not accurate (and actually not even possible.) Many of these are not really 'hacks' but code built into versions of Safari by Apple. More info is needed. I love the fact that you came here, and really want things to work out for you.

If you have issues getting something from here working on your site, please do check the test site via links below -- If a hack is working there, but not on your site, the hack is not the issue - there is something else happening with your site, often just a CSS conflict as mentioned below, or perhaps nothing is working but you may be unaware that you are not actually using Safari at all. Remember that this info is here to help people with (hopefully) short term issues.

The test site:

https://browserstrangeness.bitbucket.io/css_hacks.html#safari

AND MIRROR!

https://browserstrangeness.github.io/css_hacks.html#safari

NOTE: Filters and compilers (such as the SASS engine) expect standard 'cross-browser' code -- NOT CSS hacks like these which means they will rewrite, destroy or remove the hacks since that is not what hacks do. Much of this is non-standard code that has been painstakingly crafted to target single browser versions only and cannot work if they are altered. If you wish to use it with those, you must load your chosen CSS hack AFTER any filter or compiler. This may seem like a given but there has been a lot of confusion among people who do not realize that they are undoing a hack by running it through such software which was not designed for this purpose.

Safari has changed since version 6.1, as many have noticed.

Please note: if you are using Chrome [and now also Firefox] on iOS (at least in iOS versions 6.1 and newer) and you wonder why none of the hacks seem to be separating Chrome from Safari, it is because the iOS version of Chrome is using the Safari engine. It uses Safari hacks not the Chrome ones. More about that here: https://allthingsd.com/20120628/googles-chrome-for-ios-is-more-like-a-chrome-plated-apple/ Firefox for iOS was released in Fall 2015. It also responds to the Safari Hacks, but none of the Firefox ones, same as iOS Chrome.

ALSO: If you have tried one or more of the hacks and have trouble getting them to work, please post sample code (better yet a test page) - the hack you are attempting, and what browser(s) (exact version!) you are using as well as the device you are using. Without that additional information, it is impossible for me or anyone else here to assist you.

Often it is a simple fix or a missing semicolon. With CSS it is usually that or a problem of which order the code is listed in the style sheets, if not just CSS errors. Please do test the hacks here on the test site. If it works there, that means the hack really is working for your setup, but it is something else that needs to be resolved. People here really do love to help, or at least point you in the right direction.

That out of the way here are hacks for you to use for more recent versions of Safari.

You should try this one first as it covers current Safari versions and is pure-Safari only:

This one still works properly with Safari 13 (early-2020):

/* Safari 7.1+ */

_::-webkit-full-page-media, _:future, :root .safari_only {

  color:#0000FF; 
  background-color:#CCCCCC; 

}

To cover more versions, 6.1 and up, at this time you have to use the next pair of css hacks. The one for 6.1-10.0 to go with one that handles 10.1 and up.

So then -- here is one I worked out for Safari 10.1+:

The double media query is important here, don't remove it.

/* Safari 10.1+ */

@media not all and (min-resolution:.001dpcm) { @media {

    .safari_only { 

        color:#0000FF; 
        background-color:#CCCCCC; 

    }
}}

Try this one if SCSS or other tool set has trouble with the nested media query:

/* Safari 10.1+ (alternate method) */

@media not all and (min-resolution:.001dpcm)
{ @supports (-webkit-appearance:none) {

    .safari_only { 

        color:#0000FF; 
        background-color:#CCCCCC; 

    }
}}

This next one works for 6.1-10.0 but not 10.1 (Late March 2017 update)

This hack I created over many months of testing and experimentation by combining multiple other hacks.

NOTES: like above, the double media query is NOT an accident -- it rules out many older browsers that cannot handle media query nesting. -- The missing space after one of the 'and's is important as well. This is after all, a hack... and the only one that works for 6.1 and all newer Safari versions at this time. Also be aware as listed in the comments below, the hack is non-standard css and must be applied AFTER a filter. Filters such as SASS engines will rewrite/undo or completely remove it outright.

As mentioned above, please check my test page to see it working as-is (without modification!)

And here is the code:

/* Safari 6.1-10.0 (not 10.1) */

@media screen and (min-color-index:0) and(-webkit-min-device-pixel-ratio:0) 
{ @media {
    .safari_only { 

        color:#0000FF; 
        background-color:#CCCCCC; 

    }
}}

For more 'version specific' Safari CSS, please continue to read below.

/* Safari 11+ */

@media not all and (min-resolution:.001dpcm)
{ @supports (-webkit-appearance:none) and (stroke-color:transparent) {

    .safari_only { 

        color:#0000FF; 
        background-color:#CCCCCC; 

    }
}}

One for Safari 11.0:

/* Safari 11.0 (not 11.1) */

html >> * .safari_only {

  color:#0000FF; 
  background-color:#CCCCCC; 

}

One for Safari 10.0:

/* Safari 10.0 (not 10.1) */

_::-webkit-:host:not(:root:root), .safari_only {

  color:#0000FF; 
  background-color:#CCCCCC; 

}

Slightly modified works for 10.1 (only):

/* Safari 10.1 */

@media not all and (min-resolution:.001dpcm)
{ @supports (-webkit-appearance:none) and (not (stroke-color:transparent)) {

    .safari_only { 

        color:#0000FF; 
        background-color:#CCCCCC; 

    }
}}

Safari 10.0 (Non-iOS Devices):

/* Safari 10.0 (not 10.1) but not on iOS */

_::-webkit-:-webkit-full-screen:host:not(:root:root), .safari_only {

  color:#0000FF; 
  background-color:#CCCCCC; 

}

Safari 9 CSS Hacks:

A simple supports feature query hack for Safari 9.0 and up:

@supports (-webkit-hyphens:none)
{

  .safari_only {
    color:#0000FF; 
    background-color:#CCCCCC; 
  }

}

A simple underscore hack for Safari 9.0 and up:

_:not(a,b), .safari_only {

  color:#0000FF; 
  background-color:#CCCCCC; 

}

Another one for Safari 9.0 and up:

/* Safari 9+ */

_:default:not(:root:root), .safari_only {

  color:#0000FF; 
  background-color:#CCCCCC; 

}

and another support features query too:

/* Safari 9+ */

@supports (-webkit-marquee-repetition:infinite) and (object-fit:fill) {

    .safari_only { 

        color:#0000FF; 
        background-color:#CCCCCC; 

    }
}

One for Safari 9.0-10.0:

/* Safari 9.0-10.0 (not 10.1) */

_::-webkit-:not(:root:root), .safari_only {

  color:#0000FF; 
  background-color:#CCCCCC; 

}

Safari 9 now includes feature detection so we can use that now...

/* Safari 9 */

@supports (overflow:-webkit-marquee) and (justify-content:inherit) 
{

  .safari_only {
    color:#0000FF; 
    background-color:#CCCCCC; 
  }

}

Now to target iOS devices only. As mentioned above, since Chrome on iOS is rooted in Safari, it of course hits that one as well.

/* Safari 9.0 (iOS Only) */

@supports (-webkit-text-size-adjust:none) and (not (-ms-ime-align:auto))
and (not (-moz-appearance:none))
{

  .safari_only {
    color:#0000FF; 
    background-color:#CCCCCC; 
  }

}

one for Safari 9.0+ but not iOS devices:

/* Safari 9+ (non-iOS) */

_:default:not(:root:root), .safari_only {

  color:#0000FF; 
  background-color:#CCCCCC; 

}

And one for Safari 9.0-10.0 but not iOS devices:

/* Safari 9.0-10.0 (not 10.1) (non-iOS) */

_:-webkit-full-screen:not(:root:root), .safari_only {

  color:#0000FF; 
  background-color:#CCCCCC; 

}

Below are hacks that separate 6.1-7.0, and 7.1+ These also required a combination of multiple hacks in order to get the right result:

/* Safari 6.1-7.0 */

@media screen and (-webkit-min-device-pixel-ratio:0) and (min-color-index:0)
{  
   .safari_only {(;

      color:#0000FF; 
      background-color:#CCCCCC; 

    );}
}

Since I have pointed out the way to block iOS devices, here is the modified version of Safari 6.1+ hack that targets non-iOS devices:

/* Safari 6.1-10.0 (not 10.1) (non-iOS) */

@media screen and (min-color-index:0) and(-webkit-min-device-pixel-ratio:0) 
{ @media {
    _:-webkit-full-screen, .safari_only { 

        color:#0000FF; 
        background-color:#CCCCCC; 

    }
}}

To use them:

<div class="safari_only">This text will be Blue in Safari</div>

Usually [like in this question] the reason people ask about Safari hacks is mostly in reference to separating it from Google Chrome (again NOT iOS!) It may be important to post the alternative: how to target Chrome separately from Safari as well, so I am providing that for you here in case it is needed.

Here are the basics, again check my test page for lots of specific versions of Chrome, but these cover Chrome in general. Chrome is version 45, Dev and Canary versions are up to version 47 at this time.

My old media query combo I put on browserhacks still works just for Chrome 29+:

/* Chrome 29+ */

@media screen and (-webkit-min-device-pixel-ratio:0) and (min-resolution:.001dpcm)
{
    .chrome_only {

       color:#0000FF; 
       background-color:#CCCCCC; 

    }
}

An @supports feature query works well for Chrome 29+ as well... a modified version of the one we were using for Chrome 28+ below. Safari 9, the coming Firefox browsers, and the Microsoft Edge browser are not picked up with this one:

/* Chrome 29+ */

@supports (-webkit-appearance:none) and (not (overflow:-webkit-marquee))
and (not (-ms-ime-align:auto)) and (not (-moz-appearance:none))
{
    .chrome_only {

       color:#0000FF; 
       background-color:#CCCCCC; 

    }
}

Previously, Chrome 28 and newer were easy to target. This is one I sent to browserhacks after seeing it included within a block of other CSS code (not originally intended as a CSS hack) and realized what it does, so I extracted the relevant portion for our purposes:

[ NOTE: ] This older method below now pics up Safari 9 and the Microsoft Edge browser without the above update. The coming versions of Firefox and Microsoft Edge have added support for multiple -webkit- CSS codes in their programming, and both Edge and Safari 9 have added support for @supports feature detection. Chrome and Firefox included @supports previously.

/* Chrome 28+, Now Also Safari 9+, Firefox, and Microsoft Edge */

@supports (-webkit-appearance:none) 
{
    .chrome_and_safari {

       color:#0000FF; 
       background-color:#CCCCCC; 

    }
}

The block of Chrome versions 22-28 (If needed to support older versions) are also possible to target with a twist on my Safari combo hacks I posted above:

/* Chrome 22-28 */

@media screen and(-webkit-min-device-pixel-ratio:0)
{
    .chrome_only {-chrome-:only(;

       color:#0000FF; 
       background-color:#CCCCCC; 

    );}
}

NOTE: If you are new, change class name but leave this the same-> {-chrome-:only(;

Like the Safari CSS formatting hacks above, these can be used as follows:

<div class="chrome_only">This text will be Blue in Chrome</div>

So you don't have to search for it in this post, here is my live test page again:

https://browserstrangeness.bitbucket.io/css_hacks.html#safari

[Or the Mirror]

https://browserstrangeness.github.io/css_hacks.html#safari

The test page has many others as well, specifically version-based to further help you differentiate between Chrome and Safari, and also many hacks for Firefox, Microsoft Edge, and Internet Explorer web browsers.

NOTE: If something doesn't work for you, check the test page first, but provide example code and WHICH hack you are attempting for anyone to assist you.

First of all, please remove the "{Not using Genymotion}" from the title. It distracts readers like me who don't know what Genymotion is. The absurd here is that you got the second highest voted answer with currently 90 points which says "go to GenyMotion settings"...

The main point that all the others have missed, is that you will get this error when you have a running adb process in the background. So the first step is to find it and kill it:

ps aux | grep adb
user          46803   0.0  0.0  2442020    816 s023  S+    5:07AM   0:00.00 grep adb
user          46636   0.0  0.0   651740   3084   ??  S     5:07AM   0:00.02 adb -P 5037 fork-server server

When you find it, you can kill it using kill -9 46636.

In my case, the problem was an old version of adb coming from GapDebug. If you got this with GapDebug, get out of it and then do

adb kill-server
adb start-server

because with GapDebug in the background, when you kill the adb server, GapDebug will start its own copy immediately, causing the start-server to be ignored

The following worked for me.

var iframe = top.frames[name].document;
var css = '' +
          '<style type="text/css">' +
          'body{margin:0;padding:0;background:transparent}' +
          '</style>';
iframe.open();
iframe.write(css);
iframe.close();

Here's another way to do this:

- name: my command
  command: echo stuff
  when: "'groupname' not in group_names"

group_names is a magic variable as documented here: https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html#accessing-information-about-other-hosts-with-magic-variables :

group_names is a list (array) of all the groups the current host is in.

I started this gist a year ago: https://gist.github.com/PascalPrecht/5411171

Brian Ford (member of the core team) has written this blog post about it: http://briantford.com/blog/angular-bower

And then we started with this component spec (which is not quite complete): https://github.com/angular/angular-component-spec

Since the last ng-conf there's this document for best practices by the core team: https://docs.google.com/document/d/1XXMvReO8-Awi1EZXAXS4PzDzdNvV6pGcuaF4Q9821Es/pub

I don't believe the expression is sensical as it is.

Elvis means "if truthy, use the value, else use this other thing."

Your "other thing" is a closure, and the value is status != null, neither of which would seem to be what you want. If status is null, Elvis says true. If it's not, you get an extra layer of closure.

Why can't you just use:

(it.description == desc) && ((status == null) || (it.status == status))

Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find calls, just use an intermediate variable.

Use #include conio.h

Then add getch(); before return 0;

I think the best thing to do, if you're really concerned about the efficiency of concatenating all of these files, is to copy them all into the same bytes buffer.

buf := bytes.NewBuffer(nil)
for _, filename := range filenames {
  f, _ := os.Open(filename) // Error handling elided for brevity.
  io.Copy(buf, f)           // Error handling elided for brevity.
  f.Close()
}
s := string(buf.Bytes())

This opens each file, copies its contents into buf, then closes the file. Depending on your situation you may not actually need to convert it, the last line is just to show that buf.Bytes() has the data you're looking for.

It's Possible now with ASP.Net MVC4 Razor View engine. the code will be this:

// c# class
public class A
{
    public string Hello(string msg)
    {
        return msg + " whatewer";
    }
}

// js snippet
<script type="text/javascript">
var a = new A();
console.log('@a.Hello('Call me')'); // i have a console.log implemented, don't worry, it's not a client-side code :)
</script>

and Razor isn't just for MVC4 or another web applications and you can use it in offline desktop applications.

This can be done in the SSMS GUI as well. I show a default date below but the default value can be whatever, of course.

1. Put your table in design view (Right click on the table in object explorer->Design)
2. Add a column to the table (or click on the column you want to update if it already exists)
3. In Column Properties below, enter (getdate()) or 'abc' or 0 or whatever value you want in Default Value or Binding field as pictured below:

Attempt to connect to localhost:

SQLSTATE[HY000] [2002] No such file or directory

Attempt to connect to 127.0.0.1:

SQLSTATE[HY000] [2002] Connection refused

OK, just comment / remove the following setting from my.cnf (on OS X 10.5: /opt/local/etc/mysqlxx/my.cnf) to obtain:

[mysqld]
# skip-networking

Of course, stop and start MySQL Server.

Another succinct way of doing this is pandas.DataFrame.clip.

For example:

import pandas as pd

In [20]: df = pd.DataFrame({'a': [-1, 100, -2]})

In [21]: df
Out[21]: 
     a
0   -1
1  100
2   -2

In [22]: df.clip(lower=0)
Out[22]: 
     a
0    0
1  100
2    0

There's also df.clip_lower(0).

fill_parent :

A component is arranged layout for the fill_parent will be mandatory to expand to fill the layout unit members, as much as possible in the space. This is consistent with the dockstyle property of the Windows control. A top set layout or control to fill_parent will force it to take up the entire screen.

wrap_content

Set up a view of the size of wrap_content will be forced to view is expanded to show all the content. The TextView and ImageView controls, for example, is set to wrap_content will display its entire internal text and image. Layout elements will change the size according to the content. Set up a view of the size of Autosize attribute wrap_content roughly equivalent to set a Windows control for True.

For details Please Check out this link : http://developer.android.com/reference/android/view/ViewGroup.LayoutParams.html

One obvious thing not yet mentioned is that can be both a pro or con (and is same for both) is that they are binary protocols. This allows for more compact representation and possibly more performance (pros), but with reduced readability (or rather, debuggability), a con.

Also, both have bit less tool support than standard formats like xml (and maybe even json).

(EDIT) Here's an Interesting comparison that tackles both size & performance differences, and includes numbers for some other formats (xml, json) as well.

I don't think there is a "best way". It really will depend on the technologies and type of application you are building.

Webapps can store the information in the database as other posters have suggested, but I recommend using seperate resource files. That is resource files seperate from your source. Seperate resource files reduces contention for the same files and as your project grows you may find localization will be done seperatly from business logic. (Programmers and Translators).

Microsoft WinForm and WPF gurus recommend using seperate resource assemblies customized to each locale.

WPF's ability to size UI elements to content lowers the layout work required eg: (japanese words are much shorter than english).

If you are considering WPF: I suggest reading this msdn article To be truthful I found the WPF localization tools: msbuild, locbaml, (and maybe an excel spreadsheet) tedious to use, but it does work.

Something only slightly related: A common problem I face is integrating legacy systems that send error messages (usually in english), not error codes. This forces either changes to legacy systems, or mapping backend strings to my own error codes and then to localized strings...yech. Error codes are localizations friend

HtmlAgilityPack uses XPath syntax, and though many argues that it is poorly documented, I had no trouble using it with help from this XPath documentation: https://www.w3schools.com/xml/xpath_syntax.asp

To parse

<h2>
  <a href="">Jack</a>
</h2>
<ul>
  <li class="tel">
    <a href="">81 75 53 60</a>
  </li>
</ul>
<h2>
  <a href="">Roy</a>
</h2>
<ul>
  <li class="tel">
    <a href="">44 52 16 87</a>
  </li>
</ul>

I did this:

string url = "http://website.com";
var Webget = new HtmlWeb();
var doc = Webget.Load(url);
foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//h2//a"))
{
  names.Add(node.ChildNodes[0].InnerHtml);
}
foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//li[@class='tel']//a"))
{
  phones.Add(node.ChildNodes[0].InnerHtml);
}

This is bit out of context but in case you are here because you want to tag a specific commit like i do

Here's a command to do that :-

Example:

git tag -a v1.0 7cceb02 -m "Your message here"

Where 7cceb02 is the beginning part of the commit id.

You can then push the tag using git push origin v1.0.

You can do git log to show all the commit id's in your current branch.

Actually, you don't have to use document.getElementById("mydiv") .
You can simply use the id of the div, like:

var w = mydiv.clientWidth;
or
var w = mydiv.offsetWidth;
etc.

This method name should do the trick:

Page<QueuedBook> findByBookIdRegion(Region region, Pageable pageable);

More info on that in the section about query derivation of the reference docs.

Use the @ViewChildren decorator combined with QueryList. Both of these are from "@angular/core"

@ViewChildren(CustomComponent) customComponentChildren: QueryList<CustomComponent>;

Doing something with each child looks like: this.customComponentChildren.forEach((child) => { child.stuff = 'y' })

There is further documentation to be had at angular.io, specifically: https://angular.io/docs/ts/latest/cookbook/component-communication.html#!#sts=Parent%20calls%20a%20ViewChild

Use System.Diagnostics.Process.Start() method.

Check out this article on how to use it.

Process.Start("notepad", "readme.txt");

string winpath = Environment.GetEnvironmentVariable("windir");
string path = System.IO.Path.GetDirectoryName(
              System.Windows.Forms.Application.ExecutablePath);

Process.Start(winpath + @"\Microsoft.NET\Framework\v1.0.3705\Installutil.exe",
path + "\\MyService.exe");

I've also created a utility called goat that you can use for easier navigation.

You can view the source code on GitHub.

As of v2.3.1 the usage overview looks like this:

# Create a link (h4xdir) to a directory:
goat h4xdir ~/Documents/dev

# Follow a link to change a directory:
cd h4xdir

# Follow a link (and don't stop there!):
cd h4xdir/awesome-project

# Go up the filesystem tree with '...' (same as `cd ../../`):
cd ...

# List all your links:
goat list

# Delete a link (or more):
goat delete h4xdir lojban

# Delete all the links which point to directories with the given prefix:
goat deleteprefix $HOME/Documents

# Delete all saved links:
goat nuke

# Delete broken links:
goat fix

I know it is an old question but I came across this problem too. Just for the record, There is a little API in developers mozilla web page.

Yoy can get any cookie by name using only JS. The code is also cleaner IMHO (except for the long line, that I'm sure you can easily fix).

function getCookie(sKey) {
    if (!sKey) { return null; }
    return decodeURIComponent(document.cookie.replace(new RegExp("(?:(?:^|.*;)\\s*" + encodeURIComponent(sKey).replace(/[\-\.\+\*]/g, "\\$&") + "\\s*\\=\\s*([^;]*).*$)|^.*$"), "$1")) || null;
}

As stated in the comments be aware that this method assumes that the key and value were encoded using encodeURIComponent(). Remove decode & encodeURIComponent() if the key and value of the cookie were not encoded.

All the parameters after ? can be accessed using $_GET array. So,

echo $_GET['email'];

will extract the emails from urls.

IE 8 doesn't have indexOf function, so I used jQuery inArray instead.

$('input').datepicker({
    beforeShowDay: function(date){
        var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
        return [$.inArray(string, array) == -1];
    }
});

You could also put non-breaking spaces ( ) in lieu of the spaces so that they're forced to stay together.

How do I wrap this line of text
- asked by Peter 2 days ago

There should be

$('.send_upload')

but not $('.upload')

A very low level approach, but I belive this would be the most performant way by only using fast integer calculations (and no slow string parsing and culture sensitive methods):

public static decimal Normalize(this decimal d)
{
    int[] bits = decimal.GetBits(d);

    int sign = bits[3] & (1 << 31);
    int exp = (bits[3] >> 16) & 0x1f;

    uint a = (uint)bits[2]; // Top bits
    uint b = (uint)bits[1]; // Middle bits
    uint c = (uint)bits[0]; // Bottom bits

    while (exp > 0 && ((a % 5) * 6 + (b % 5) * 6 + c) % 10 == 0)
    {
        uint r;
        a = DivideBy10((uint)0, a, out r);
        b = DivideBy10(r, b, out r);
        c = DivideBy10(r, c, out r);
        exp--;
    }

    bits[0] = (int)c;
    bits[1] = (int)b;
    bits[2] = (int)a;
    bits[3] = (exp << 16) | sign;
    return new decimal(bits);
}

private static uint DivideBy10(uint highBits, uint lowBits, out uint remainder)
{
    ulong total = highBits;
    total <<= 32;
    total = total | (ulong)lowBits;

    remainder = (uint)(total % 10L);
    return (uint)(total / 10L);
}

fun fact: height-100% works in the latest chrome; but not in safari;

so solution in tailwind would be

"flex items-stretch"

Please set your form action attribute as below it will solve your problem.

<form name="addProductForm" id="addProductForm" action="javascript:;" enctype="multipart/form-data" method="post" accept-charset="utf-8">

jQuery code:

$(document).ready(function () {
    $("#addProductForm").submit(function (event) {

        //disable the default form submission
        event.preventDefault();
        //grab all form data  
        var formData = $(this).serialize();

        $.ajax({
            url: 'addProduct.php',
            type: 'POST',
            data: formData,
            async: false,
            cache: false,
            contentType: false,
            processData: false,
            success: function () {
                alert('Form Submitted!');
            },
            error: function(){
                alert("error in ajax form submission");
            }
        });

        return false;
    });
});

Yes, Just be careful if you are also iterating over the list, because in this case you will need to synchronize on it. From the Javadoc:

It is imperative that the user manually synchronize on the returned list when iterating over it:

List list = Collections.synchronizedList(new ArrayList());
    ...
synchronized (list) {
    Iterator i = list.iterator(); // Must be in synchronized block
    while (i.hasNext())
        foo(i.next());
}

Or, you can use CopyOnWriteArrayList which is slower for writes but doesn't have this issue.

I found it, I was trying to compile my app which is using facebook sdk. I was made that like augst 2016. When I try to open it today i got same error. I had that line in my gradle " compile 'com.facebook.android:facebook-android-sdk:4.+' " and I went https://developers.facebook.com/docs/android/change-log-4x this page and i found the sdk version while i was running this app succesfully and it was 4.14.1 then I changed that line to " compile 'com.facebook.android:facebook-android-sdk:4.14.1' " and it worked.

Or if the Boolean value is not been returned, you can do something like this:

bool boolValue = (returnValue == "1");

Two ways to get this done:

Collections.sort(myArray)

given elements inside myArray implements Comparable

Second

Collections.sort(myArray, new MyArrayElementComparator());

where MyArrayElementComparator is Comparator for elements inside myArray

I have faced this issue, my certificates where having private key but i was getting this error("Keyset does not exist")

Cause: Your web site is running under "Network services" account or having less privileges.

Solution: Change Application pool identity to "Local System", reset IIS and check again. If it starts working it is permission/Less privilege issue, you can impersonate then using other accounts too.

I encountered the same problem when I was trying to compile a sample project provided by Apple. In the end I figured out that apparently they pre-compiled the sample code before shipping them to developers, so the binary had their signature.

The way to solve it is simple, just delete all the built binaries and re-compile using your own bundle identifier and you should be fine.

Just go to the menu bar, click on [Product] -> [Clean Build Folder] to delete all compiled binaries

Clean Build Folder

This is an old post but I have issues with coming across posts that have some incorrect information/syntax...

If you wanted to do this with a shorcut icon you could just create a shortcut on your desktop for the cmd.exe application. Then append a /K {your command} to the shorcut path.

So a default shorcut target path may look like "%windir%\system32\cmd.exe", just change it to %windir%\system32\cmd.exe /k {commands}

example: %windir%\system32\cmd.exe /k powercfg -lastwake

In this case i would use /k (keep open) to display results.

Arlen was right about the /k (keep open) and /c (close)

You can open a command prompt and type "cmd /?" to see your options.

http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/cmd.mspx?mfr=true

A batch file is kind of overkill for a single command prompt command...

Hope this helps someone else

The error regarding the file extension has been handled, you either use BMP (without the dot) or pass the output name with the extension already. Now to handle the error you need to properly modify your data in the frequency domain to be saved as an integer image, PIL is telling you that it doesn't accept float data to save as BMP.

Here is a suggestion (with other minor modifications, like using fftshift and numpy.array instead of numpy.asarray) for doing the conversion for proper visualization:

import sys
import numpy
from PIL import Image

img = Image.open(sys.argv[1]).convert('L')

im = numpy.array(img)
fft_mag = numpy.abs(numpy.fft.fftshift(numpy.fft.fft2(im)))

visual = numpy.log(fft_mag)
visual = (visual - visual.min()) / (visual.max() - visual.min())

result = Image.fromarray((visual * 255).astype(numpy.uint8))
result.save('out.bmp')

You could translate each string to lowercase once --- lazily only when you need it, or as a prepass to the sort if you know you'll be sorting the entire collection of strings. There are several ways to attach this comparison key to the actual data being sorted, but these techniques should be addressed in a separate issue.

Note that this technique can be used not only to handle upper/lower case issues, but for other types of sorting such as locale specific sorting, or "Library-style" title sorting that ignores leading articles and otherwise normalizes the data before sorting it.

Subclass the ArrayAdapter and override the method getView() to return your own view that contains the contents that you want to display.

You can use the pathinfo() function built into PHP for that:

$info = pathinfo(storage_path().'/uploads/categories/featured_image.jpg');
$ext = $info['extension'];

Or more concisely, you can pass an option get get it directly;

$ext = pathinfo(storage_path().'/uploads/categories/featured_image.jpg', PATHINFO_EXTENSION);

Here's a nice hack for windows

process.on('exit', async () => {
    require('fs').writeFileSync('./tmp.js', 'crash', 'utf-8')
});

It depends on the GC your java is using. Parallel GCs might work better on larger memory settings - I'm no expert on that though.

In general, if you have larger memory the less frequent it needs to be GC-ed - there is lots of room for garbage. However, when it comes to a GC, the GC has to work on more memory - which in turn might be slower.

The lodash 4.6.1 docs have this as an example for object key equality:

_.uniqWith(objects, _.isEqual);

https://lodash.com/docs#uniqWith

Leveraging from the good answers above and assuming you were only using plt as in

import matplotlib.pyplot as plt

then you can get all four plot limits using plt.axis() as in the following example.

import matplotlib.pyplot as plt

x = [1, 2, 3, 4, 5, 6, 7, 8]  # fake data
y = [1, 2, 3, 4, 3, 2, 5, 6]

plt.plot(x, y, 'k')

xmin, xmax, ymin, ymax = plt.axis()

s = 'xmin = ' + str(round(xmin, 2)) + ', ' + \
    'xmax = ' + str(xmax) + '\n' + \
    'ymin = ' + str(ymin) + ', ' + \
    'ymax = ' + str(ymax) + ' '

plt.annotate(s, (1, 5))

plt.show()

The above code should produce the following output plot.

I had a similar problem trying to POST to MailGun for some automated emails I was implementing in an app.

I was able to get this working properly with a large HTTP response. I put the full path into Keys.plist so that I can upload my code to github and broke out some of the arguments into variables so I can have them programmatically set later down the road.

// Email the FBO with desired information
// Parse our Keys.plist so we can use our path
var keys: NSDictionary?

if let path = NSBundle.mainBundle().pathForResource("Keys", ofType: "plist") {
    keys = NSDictionary(contentsOfFile: path)
}

if let dict = keys {
    // variablize our https path with API key, recipient and message text
    let mailgunAPIPath = dict["mailgunAPIPath"] as? String
    let emailRecipient = "[email protected]"
    let emailMessage = "Testing%20email%20sender%20variables"

    // Create a session and fill it with our request
    let session = NSURLSession.sharedSession()
    let request = NSMutableURLRequest(URL: NSURL(string: mailgunAPIPath! + "from=FBOGo%20Reservation%20%3Cscheduler@<my domain>.com%3E&to=reservations@<my domain>.com&to=\(emailRecipient)&subject=A%20New%20Reservation%21&text=\(emailMessage)")!)

    // POST and report back with any errors and response codes
    request.HTTPMethod = "POST"
    let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
        if let error = error {
            print(error)
        }

        if let response = response {
            print("url = \(response.URL!)")
            print("response = \(response)")
            let httpResponse = response as! NSHTTPURLResponse
            print("response code = \(httpResponse.statusCode)")
        }
    })
    task.resume()
}

The Mailgun Path is in Keys.plist as a string called mailgunAPIPath with the value:

https://API:key-<my key>@api.mailgun.net/v3/<my domain>.com/messages?

Hope this helps offers a solution to someone trying to avoid using 3rd party code for their POST requests!

This is all you need.

 rsync -e ssh file host:/directory/.

Pardon my ignorance, but why are you using $('.salesperson') instead of $('#salesperson') when dealing with an ID?

Calendar cal = Calendar.getInstance(); 
cal.add(Calendar.MONTH, 1);

In projects that use the Gradle build system, what you want to change is the applicationId in the build.gradle file. The build system uses this value to override anything specified by hand in the manifest file when it does the manifest merge and build.

For example, your module's build.gradle file looks something like this:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion "20.0.0"

    defaultConfig {
        // CHANGE THE APPLICATION ID BELOW
        applicationId "com.example.fred.myapplication"
        minSdkVersion 10
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
}

applicationId is the name the build system uses for the property that eventually gets written to the package attribute of the manifest tag in the manifest file. It was renamed to prevent confusion with the Java package name (which you have also tried to modify), which has nothing to do with it.

OS X alternative: The solution described earlier based on [[NSProcessInfo processInfo] processorCount] is only available on OS X 10.5.0, according to the docs. For earlier versions of OS X, use the Carbon function MPProcessors().

If you're a Cocoa programmer, don't be freaked out by the fact that this is Carbon. You just need to need to add the Carbon framework to your Xcode project and MPProcessors() will be available.

The answer is, "No."

What C programmers do is store the size of the array somewhere. It can be part of a structure, or the programmer can cheat a bit and malloc() more memory than requested in order to store a length value before the start of the array.

I cannot get a match using Xpather, but the following worked for me with plain XML and XSL files in Microsoft's XML Notepad:

<xsl:value-of select="count(//td[text()='&nbsp;'])" />

The value returned is 1, which is the correct value in my test case.

However, I did have to declare nbsp as an entity within my XML and XSL using the following:

<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#160;"> ]>

I'm not sure if that helps you, but I was able to actually find nbsp using an XPath expression.

Edit: My code sample actually contains the characters ' ' but the JavaScript syntax highlight converts it to the space character. Don't be mislead!

To check for all int chars, you can simply use a double negative. if (!searchString.matches("[^0-9]+$")) ...

[^0-9]+$ checks to see if there are any characters that are not integer, so the test fails if it's true. Just NOT that and you get true on success.

If you are unable to install with either of these:

sudo apt-get install python-distutils
sudo apt-get install python3-distutils

Try this instead:

sudo apt-get install python-distutils-extra

As far as I know you can't do that, I may be wrong. However I'd do this with php, generate a JPEG using php standard functions and then display the image, should not be a very hard job, however depends on how flashy the contents of the DIV are

String phoneNumberstr = "Tel: 00971-557890-999";
String numberRefined = phoneNumberstr.replaceAll("[^\\d-]", "");

result: 0097-557890-999

if you also do not need "-" in String you can do like this:

String phoneNumberstr = "Tel: 00971-55 7890 999";      
String numberRefined = phoneNumberstr.replaceAll("[^0-9]", "");

result: 0097557890999

you can use

var match=myList.Where(item=>item.Contains("Required String"));
foreach(var i in match)
{
//do something with the matched items
}

LINQ provides you with capabilities to "query" any collection of data. You can use syntax like a database query (select, where, etc) on a collection (here the collection (list) of strings).

so you are doing like "get me items from the list Where it satisfies a given condition"

inside the Where you are using a "lambda expression"

to tell briefly lambda expression is something like (input parameter => return value)

so for a parameter "item", it returns "item.Contains("required string")" . So it returns true if the item contains the string and thereby it gets selected from the list since it satisfied the condition.

Try to check outline on button's focus:

button:focus {
    outline: blue auto 5px; 
}

If you have it, just set it to none.

I am trying to get int x equal to 5 (as seen in the setNum() method) but when it prints it gives me 0.

To run the code in setNum you have to call it. If you don't call it, the default value is 0.

This question has more than 30 answers already. I am going to summarize and explain them (with a "my father" analogy) and add my suggested solution.

You have 4+1 classes of solutions:

1) Use a hacky incomplete quick one-liner

Good if you are in a rush and 99% correctness works.

Examples of this is, JSON.stringify() suggested by Pratik Bhalodiya, or JSON.encode by Joel Anair, or .toString(), or other methods that transform your objects into a String and then compare the two Strings using === character by character.

The drawback, however, is that there is no globally standard unique representation of an Object in String. e.g. { a: 5, b: 8} and {b: 8 and a: 5 } are equal.

• Pros: Fast, quick.
• Cons: Hopefully works! It will not work if the environment/browser/engine memorizes the ordering for objects (e.g. Chrome/V8) and the order of the keys are different (Thanks to Eksapsy.) So, not guaranteed at all. Performance wouldn't be great either in large objects.

My Father Analogy

When I am talking about my father, "my tall handsome father" and "my handsome tall father" are the same person! But the two strings are not the same.

Note that there is actually a correct (standard way) order of adjectives in English grammar, which says it should be a "handsome tall man," but you are risking your competency if you blindly assume Javascript engine of iOS 8 Safari is also abiding the same grammar, blindly! #WelcomeToJavascriptNonStandards

2) Write your own DIY recursive function

Good if you are learning.

Examples are atmin's solution.

The biggest disadvantage is you will definitely miss some edge cases. Have you considered a self-reference in object values? Have you considered NaN? Have you considered two objects that have the same ownProperties but different prototypical parents?

I would only encourage people to do this if they are practicing and the code is not going to go in production. That's the only case that reinventing the wheel has justifications.

• Pros: Learning opportunity.
• Cons: Not reliable. Takes time and concerns.

My Father Analogy

It's like assuming if my dad's name is "John Smith" and his birthday is "1/1/1970", then anyone whose name is "John Smith" and is born on "1/1/1970" is my father.

That's usually the case, but what if there are two "John Smith"s born on that day? If you think you will consider their height, then that's increasing the accuracy but still not a perfect comparison.

2.1 You limited scope DIY comparator

Rather than going on a wild chase of checking all the properties recursively, one might consider checking only "a limited" number of properties. For instance, if the objects are Users, you can compare their emailAddress field.

It's still not a perfect one, but the benefits over solution #2 are:

1. It's predictable, and it's less likely to crash.
2. You are driving the "definition" of equality, rather than relying on a wild form and shape of the Object and its prototype and nested properties.

3) Use a library version of equal function

Good if you need a production-level quality, and you cannot change the design of the system.

Examples are _.equal of lodash, already in coolaj86's answer or Angular's or Ember's as mentioned in Tony Harvey's answer or Node's by Rafael Xavier.

• Pros: It's what everyone else does.
• Cons: External dependency, which can cost you extra memory/CPU/Security concerns, even a little bit. Also, can still miss some edge cases (e.g. whether two objects having same ownProperties but different prototypical parents should be considered the same or not.) Finally, you might be unintentionally band-aiding an underlying design problem with this; just saying!

My Father Analogy

It's like paying an agency to find my biological father, based on his phone, name, address, etc.

It's gonna cost more, and it's probably more accurate than myself running the background check, but doesn't cover edge cases like when my father is immigrant/asylum and his birthday is unknown!

4) Use an IDentifier in the Object

Good if you [still] can change the design of the system (objects you are dealing with) and you want your code to last long.

It's not applicable in all cases, and might not be very performant. However, it's a very reliable solution, if you can make it.

The solution is, every object in the system will have a unique identifier along with all the other properties. The uniqueness of the identifier will be guaranteed at the time of generation. And you will use this ID (also known as UUID/GUID -- Globally/Universally Unique Identifier) when it comes to comparing two objects. i.e. They are equal if and only if these IDs are equal.

The IDs can be simple auto_incremental numbers, or a string generated via a library (advised) or a piece of code. All you need to do is make sure it's always unique, which in case of auto_incremental it can be built-in, or in case of UUID, can be checked will all existing values (e.g. MySQL's UNIQUE column attribute) or simply (if coming from a library) be relied upon giving the extremely low likelihood of a collision.

Note that you also need to store the ID with the object at all times (to guarantee its uniqueness), and computing it in real-time might not be the best approach.

• Pros: Reliable, efficient, not dirty, modern.
• Cons: Needs extra space. Might need a redesign of the system.

My Father Analogy

It's like known my father's Social Security Number is 911-345-9283, so anyone who has this SSN is my father, and anyone who claims to be my father must have this SSN.

Conclusion

I personally prefer solution #4 (ID) over them all for accuracy and reliability. If it's not possible I'd go with #2.1 for predictability, and then #3. If neither is possible, #2 and finally #1.

The best HTTP header for your client to send an access token (JWT or any other token) is the Authorization header with the Bearer authentication scheme.

This scheme is described by the RFC6750.

Example:

GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer eyJhbGciOiJIUzI1NiIXVCJ9TJV...r7E20RMHrHDcEfxjoYZgeFONFh7HgQ

If you need stronger security protection, you may also consider the following IETF draft: https://tools.ietf.org/html/draft-ietf-oauth-pop-architecture. This draft seems to be a good alternative to the (abandoned?) https://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac.

Note that even if this RFC and the above specifications are related to the OAuth2 Framework protocol, they can be used in any other contexts that require a token exchange between a client and a server.

Unlike the custom JWT scheme you mention in your question, the Bearer one is registered at the IANA.

Concerning the Basic and Digest authentication schemes, they are dedicated to authentication using a username and a secret (see RFC7616 and RFC7617) so not applicable in that context.

An object file is just what you get when you compile one (or several) source file(s).

It can be either a fully completed executable or library, or intermediate files.

The object files typically contain native code, linker information, debugging symbols and so forth.

Percentage in width works but percentage in height will not work unless you specify a specific height for any parent in the dependent loop...

See this : percentage in height doesn’t work?

Set up HADOOP_HOME variable in windows to resolve the problem.

You can find answer in org/apache/hadoop/hadoop-common/2.2.0/hadoop-common-2.2.0-sources.jar!/org/apache/hadoop/util/Shell.java :

IOException from

  public static final String getQualifiedBinPath(String executable) 
  throws IOException {
    // construct hadoop bin path to the specified executable
    String fullExeName = HADOOP_HOME_DIR + File.separator + "bin" 
      + File.separator + executable;
    File exeFile = new File(fullExeName);
    if (!exeFile.exists()) {
      throw new IOException("Could not locate executable " + fullExeName
        + " in the Hadoop binaries.");
    }
    return exeFile.getCanonicalPath();
  }

HADOOP_HOME_DIR from

// first check the Dflag hadoop.home.dir with JVM scope
String home = System.getProperty("hadoop.home.dir");
// fall back to the system/user-global env variable
if (home == null) {
  home = System.getenv("HADOOP_HOME");
}

Here is another cool way to do it- using en external viewer that accepts command line switches (IrfanView in this case) : * I based the loop on what Michal Krzych has written above.

Sub ExportPicturesToFiles()
    Const saveSceenshotTo As String = "C:\temp\"
    Const pictureFormat As String = ".jpg"

    Dim pic As Shape
    Dim sFileName As String
    Dim i As Long

    i = 1

    For Each pic In ActiveSheet.Shapes
        pic.Copy
        sFileName = saveSceenshotTo & Range("A" & i).Text & pictureFormat

        Call ExportPicWithIfran(sFileName)

        i = i + 1
    Next
End Sub

Public Sub ExportPicWithIfran(sSaveAsPath As String)
    Const sIfranPath As String = "C:\Program Files\IrfanView\i_view32.exe"
    Dim sRunIfran As String

    sRunIfran = sIfranPath & " /clippaste /convert=" & _
                            sSaveAsPath & " /killmesoftly"

    ' Shell is no good here. If you have more than 1 pic, it will
    ' mess things up (pics will over run other pics, becuase Shell does
    ' not make vba wait for the script to finish).
    ' Shell sRunIfran, vbHide

    ' Correct way (it will now wait for the batch to finish):
    call MyShell(sRunIfran )
End Sub

Edit:

I ran into this exact issue today. I had copied the entire /etc/httpd from RHEL 6 and put it onto a CentOS 6 system, and ensured all RPMs were installed.

Anytime apache would be started, it would silently fail. It took an strace to find the culprit: I was using CustomLog to call a program that was not installed on the target system. Once I installed the expected program, Apache HTTP Server started right up.

You can reset the index using reset_index to get back a default index of 0, 1, 2, ..., n-1 (and use drop=True to indicate you want to drop the existing index instead of adding it as an additional column to your dataframe):

In [19]: df2 = df2.reset_index(drop=True)

In [20]: df2
Out[20]:
   x  y
0  0  0
1  0  1
2  0  2
3  1  0
4  1  1
5  1  2
6  2  0

The problem with showing a file using Intent.ACTION_VIEW, is that if you pass the Uri parsing the path. Doesn't work in all cases. To fix that problem, you need to use:

Uri.fromFile(new File(filePath));

Instead of:

Uri.parse(filePath);

Edit

Here is my complete code:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(mediaFile.filePath)), mediaFile.getExtension());
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

Info

MediaFile is my domain class to wrap files from database in objects. MediaFile.getExtension() returns a String with Mimetype for the file extension. Example: "image/png"

Aditional code: needed for showing any file (extension)

import android.webkit.MimeTypeMap;

public String getExtension () {
    MimeTypeMap myMime = MimeTypeMap.getSingleton();
    return myMime.getMimeTypeFromExtension(MediaFile.fileExtension(filePath));
}

public static String fileExtension(String path) {
    if (path.indexOf("?") > -1) {
        path = path.substring(0, path.indexOf("?"));
    }
    if (path.lastIndexOf(".") == -1) {
        return null;
    } else {
        String ext = path.substring(path.lastIndexOf(".") + 1);
        if (ext.indexOf("%") > -1) {
            ext = ext.substring(0, ext.indexOf("%"));
        }
        if (ext.indexOf("/") > -1) {
            ext = ext.substring(0, ext.indexOf("/"));
        }
        return ext.toLowerCase();
    }
}

Let me know if you need more code.

The most important thing to know is that ES6 modules are, indeed, an official standard, while CommonJS (Node.js) modules are not.

In 2019, ES6 modules are supported by 84% of browsers. While Node.js puts them behind an --experimental-modules flag, there is also a convenient node package called esm, which makes the integration smooth.

Another issue you're likely to run into between these module systems is code location. Node.js assumes source is kept in a node_modules directory, while most ES6 modules are deployed in a flat directory structure. These are not easy to reconcile, but it can be done by hacking your package.json file with pre and post installation scripts. Here is an example isomorphic module and an article explaining how it works.

I thought I could add a method I use in many projects.

- (NSInteger)randomValueBetween:(NSInteger)min and:(NSInteger)max {
    return (NSInteger)(min + arc4random_uniform(max - min + 1));
}

If I end up using it in many files I usually declare a macro as

#define RAND_FROM_TO(min, max) (min + arc4random_uniform(max - min + 1))

E.g.

NSInteger myInteger = RAND_FROM_TO(0, 74) // 0, 1, 2,..., 73, 74

Note: Only for iOS 4.3/OS X v10.7 (Lion) and later

Simplest no code solution was to init an array with the range, and use the $index + however much I want to offset by:

<select ng-init="(_Array = []).length = 5;">
    <option ng-repeat="i in _Array track by $index">{{$index+5}}</option>
</select>

According to the discussion here you can directly compare two vectors using

==

if (vector1 == vector2){
   //true
}
else{
   //false
}

I have inherited a desktop app that makes calls to a series of Web Services on IIS. The web services (also) have to be able to run timed processes, independently (without having the client on). Hence they all have timers. The web service timers were shutting down (memory leak?) so we set the Idle time out to 0 and timers stay on.

If you want some custom mapping (like original Array.prototype.map) of Object into an Array, you can just use _.forEach:

let myObject = {
  key1: "value1",
  key2: "value2",
  // ...
};

let myNewArray = [];

_.forEach(myObject, (value, key) => {
  myNewArray.push({
    someNewKey: key,
    someNewValue: value.toUpperCase() // just an example of new value based on original value
  });
});

// myNewArray => [{ someNewKey: key1, someNewValue: 'VALUE1' }, ... ];

See lodash doc of _.forEach https://lodash.com/docs/#forEach

var attr = $(this).attr('name');

// For some browsers, `attr` is undefined; for others,
// `attr` is false.  Check for both.
if (typeof attr !== typeof undefined && attr !== false) {
    // ...
}

lapsList() {

    return this.state.laps.map((data) => {
      return (
        <View><Text>{data.time}</Text></View>
      )
    })
}

You forgot to return the map. this code will resolve the issue.

I'm not sure what you're trying to achieve, but you may want to consider using jQuery, which allows you to put your code in the head tag or a separate script file and still have the code executed after the DOM has loaded.

You can then do something like:

$(document).ready(function() {
$(document).remove();
});

as well as selectively removing elements (all DIVs, only DIVs with certain classes, etc.)

I used %matplotlib inline in the first cell of the notebook and it works. I think you should try:

%matplotlib inline

import matplotlib
import numpy as np
import matplotlib.pyplot as plt

You can also always start all your IPython kernels in inline mode by default by setting the following config options in your config files:

c.IPKernelApp.matplotlib=<CaselessStrEnum>
  Default: None
  Choices: ['auto', 'gtk', 'gtk3', 'inline', 'nbagg', 'notebook', 'osx', 'qt', 'qt4', 'qt5', 'tk', 'wx']
  Configure matplotlib for interactive use with the default matplotlib backend.

Even though above answers are correct, I wanna add a notice to distinguish types of storage:

• Internal storage: It should say 'private storage' because it belongs to the app and cannot be shared. Where it's saved is based on where the app installed. If the app was installed on an SD card (I mean the external storage card you put more into a cell phone for more space to store images, videos, ...), your file will belong to the app means your file will be in an SD card. And if the app was installed on an Internal card (I mean the onboard storage card coming with your cell phone), your file will be in an Internal card.
• External storage: It should say 'public storage' because it can be shared. And this mode divides into 2 groups: private external storage and public external storage. Basically, they are nearly the same, you can consult more from this site: https://developer.android.com/training/data-storage/files
• A real SD card (I mean the external storage card you put more into a cell phone for more space to store images, videos, ...): this was not stated clearly on Android docs, so many people might be confused with how to save files in this card.

Here is the link to source code for cases I mentioned above: https://github.com/mttdat/utils/blob/master/utils/src/main/java/mttdat/utils/FileUtils.java

Tab and Shift+Tab will do that.

Another cool trick is holding down ALT when you select text, it will allow you to make a square selection. Starting with VS2010, you can start typing and it will replace the contents of your square selection with what you type. Absolutely awesome for changing a bunch of lines at once.

For simplicity and well structured sake, use SpringMVC. It's just so simple.

@RequestMapping("/carlist.json")
public @ResponseBody List<String> getCarList() {
    return carService.getAllCars();
}

Regarding conventions in C#. Let's say you're reading a cell that contains a date, e.g. 2014-10-22.

When using:

.Text, you'll get the formatted representation of the date, as seen in the workbook on-screen:
2014-10-22. This property's type is always string but may not always return a satisfactory result.

.Value, the compiler attempts to convert the date into a DateTime object: {2014-10-22 00:00:00} Most probably only useful when reading dates.

.Value2, gives you the real, underlying value of the cell. In the case for dates, it's a date serial: 41934. This property can have a different type depending on the contents of the cell. For date serials though, the type is double.

So you can retrieve and store the value of a cell in either dynamic, var or object but note that the value will always have some sort of innate type that you will have to act upon.

dynamic x = ws.get_Range("A1").Value2;
object  y = ws.get_Range("A1").Value2;
var     z = ws.get_Range("A1").Value2;
double  d = ws.get_Range("A1").Value2;      // Value of a serial is always a double

Using the luxon.js library, same can be achieved using startOf and endOf methods by passing the 'day' as parameter

var DateTime = luxon.DateTime;
DateTime.local().startOf('day').toUTC().toISO(); //2017-11-16T18:30:00.000Z
DateTime.local().endOf('day').toUTC().toISO(); //2017-11-17T18:29:59.999Z
DateTime.fromISO(new Date().toISOString()).startOf('day').toUTC().toISO(); //2017-11-16T18:30:00.000Z

remove .toUTC() if you need only the local time

and you may ask why not moment.js, answer is here for that.

The characters you are reading on your screen now each have a numerical value. In the ASCII format, for example, the letter 'A' is 65, 'B' is 66, and so on. If you look at a table of characters available in ASCII you will see that it isn't much use for someone who wishes to write something in Mandarin, Arabic, or Japanese. For characters / words from those languages to be displayed we needed another system of encoding them to and from numbers stored in computer memory.

UTF-8 is just one of the encoding methods that were invented to implement this requirement. It lets you write text in all kinds of languages, so French accents will appear perfectly fine, as will text like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

If you copy and paste the above text into notepad and then try to save the file as ANSI (another format) you will receive a warning that saving in this format will lose some of the formatting. Accept it, then re-load the text file and you'll see something like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

The problem is going to be that you probably have no good means of keeping up with the changing postal code requirements of countries on the other side of the globe and which you share no common languages. Unless you have a large enough budget to track this, you are almost certainly better off giving the responsibility of validating addresses to google or yahoo.

Both companies provide address lookup facuilities through a programmable API.

As slashnick pointed out, you can use the "for in" construct to iterate over an object for its attribute names. However you'll be iterating over all attribute names in the object's prototype chain. If you want to iterate only over the object's own attributes, you can make use of the Object#hasOwnProperty() method. Thus having the following.

for (var key in obj) {
    if (obj.hasOwnProperty(key)) {
        /* useful code here */
    }
}

The following is nasty, but serves to demonstrate how you can treat functions like any other kind of object.

var foo = function () { alert('default function'); }

function pickAFunction(a_or_b) {
    var funcs = {
        a: function () {
            alert('a');
        },
        b: function () {
            alert('b');
        }
    };
    foo = funcs[a_or_b];
}

foo();
pickAFunction('a');
foo();
pickAFunction('b');
foo();

This works for stdlib on Python 3.2 onwards (assuming all the timestamps are UTC):

from datetime import datetime, timezone, timedelta
datetime.strptime(timestamp, "%Y-%m-%dT%H:%M:%S.%fZ").replace(
    tzinfo=timezone(timedelta(0)))

For example,

>>> datetime.utcnow().replace(tzinfo=timezone(timedelta(0)))
... datetime.datetime(2015, 3, 11, 6, 2, 47, 879129, tzinfo=datetime.timezone.utc)

The accepted answer by Adam (flex: 1 1 0) works perfectly for flexbox containers whose width is either fixed, or determined by an ancestor. Situations where you want the children to fit the container.

However, you may have a situation where you want the container to fit the children, with the children equally sized based on the largest child. You can make a flexbox container fit its children by either:

• setting position: absolute and not setting width or right, or
• place it inside a wrapper with display: inline-block

For such flexbox containers, the accepted answer does NOT work, the children are not sized equally. I presume that this is a limitation of flexbox, since it behaves the same in Chrome, Firefox and Safari.

The solution is to use a grid instead of a flexbox.

Demo: https://codepen.io/brettdonald/pen/oRpORG

<p>Normal scenario — flexbox where the children adjust to fit the container — and the children are made equal size by setting {flex: 1 1 0}</p>

<div id="div0">
  <div>
    Flexbox
  </div>
  <div>
    Width determined by viewport
  </div>
  <div>
    All child elements are equal size with {flex: 1 1 0}
  </div>
</div>

<p>Now we want to have the container fit the children, but still have the children all equally sized, based on the largest child. We can see that {flex: 1 1 0} has no effect.</p>

<div class="wrap-inline-block">
<div id="div1">
  <div>
    Flexbox
  </div>
  <div>
    Inside inline-block
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>
</div>

<div id="div2">
  <div>
    Flexbox
  </div>
  <div>
    Absolutely positioned
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>

<br><br><br><br><br><br>
<p>So let's try a grid instead. Aha! That's what we want!</p>

<div class="wrap-inline-block">
<div id="div3">
  <div>
    Grid
  </div>
  <div>
    Inside inline-block
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>
</div>

<div id="div4">
  <div>
    Grid
  </div>
  <div>
    Absolutely positioned
  </div>
  <div>
    We want all children to be the size of this text

Starting with Android 11, you can directly bring up the app-specific settings page for the location permission only using code like this: requestPermissions(arrayOf(Manifest.permission.ACCESS_BACKGROUND_LOCATION), PERMISSION_REQUEST_BACKGROUND_LOCATION)

However, the above will only work one time. If the user denies the permission or even accidentally dismisses the screen, the app can never trigger this to come up again.

Other than the above, the answer remains the same as prior to Android 11 -- the best you can do is bring up the app-specific settings page and ask the user to drill down two levels manually to enable the proper permission.

val intent = Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS)
val uri: Uri = Uri.fromParts("package", packageName, null)
intent.data = uri
// This will take the user to a page where they have to click twice to drill down to grant the permission
startActivity(intent)

See my related question here: Android 11 users can’t grant background location permission?

You can use the following code for your requirement

map.forEach((k,v)->System.out.println("Item : " + k + " Count : " + v));

Just an update, Feb 1, 2019: cmd+shift+n on Mac now opens a new window where you can drag over tabs. I didn't find that out until I when through KyleMit's response and saw his key mapping suggestion was already mapped to the correct action.

some thing as follows ::

Add this After the body tag

This is a rough sketch, you will need to modify it according to your needs.

<script>
var f = document.createElement("form");
f.setAttribute('method',"post");
f.setAttribute('action',"submit.php");

var i = document.createElement("input"); //input element, text
i.setAttribute('type',"text");
i.setAttribute('name',"username");

var s = document.createElement("input"); //input element, Submit button
s.setAttribute('type',"submit");
s.setAttribute('value',"Submit");

f.appendChild(i);
f.appendChild(s);

//and some more input elements here
//and dont forget to add a submit button

document.getElementsByTagName('body')[0].appendChild(f);

This question came up on stackexchange security, one of the suggestions was to use Keystore explorer

https://security.stackexchange.com/questions/3779/how-can-i-export-my-private-key-from-a-java-keytool-keystore

Having just tried it, it works really well and I strongly recommend it.

You can use the binary instead, I ran into the issue in dockerizing the application when Django tried to install it as part of its dependencies, to resolve that, I used this setup for requirements.txt where the binary is installed first and then django does not try to install it again: psycopg2-binary django gunicorn

You're missing a FROM and you need to give the subquery an alias.

SELECT COUNT(*) FROM 
(
  SELECT DISTINCT a.my_id, a.last_name, a.first_name, b.temp_val
   FROM dbo.Table_A AS a 
   INNER JOIN dbo.Table_B AS b 
   ON a.a_id = b.a_id
) AS subquery;

Here's a dplyr option:

library(dplyr)

# across all columns:
df %>% filter_all(any_vars(. %in% c('M017', 'M018')))

# or in only select columns:
df %>% filter_at(vars(col1, col2), any_vars(. %in% c('M017', 'M018')))                                                                                                     

On linux systems:

~/.sqldeveloper/system<sqldeveloper_version>/o.jdeveloper.db.connection/connections.xml

Solution :Laravel Migration table already exists... || It Works in Laravel 5.8 also

app\Providers\AppServiceProvider.php file

and inside the boot method set a default string length:

public function boot()
{
    Schema::defaultStringLength(191);
}

and open

config\database.php

'charset' =>'utf8mb4',
'collation' =>'utf8mb4_unicode_ci',

and change it to

'charset' =>'utf8',
'collation' =>'utf8_unicode_ci',

save all the files and go to command prompt

php artisan migrate

For anyone having same error for the same reason in ADOS CI Build:

This question was the first I found when looking for help. I have an ADOS CI build pipeline where first Node.js tool installer task is used to install Node. Then npm task is used to install gulp (npm install -g gulp). Then the following Gulp task runs default-task from gulpfile.js. There's some gulp-sass stuff in it.

When I changed the Node.js tool to install 12.x latest node instead of an older one and the latest gulp version was 4.0.2. The result was the same error as described in the question.

What worked for me in this case was to downgrade node.js to latest 11.x version as was already suggested by Alphonse R. Dsouza and Aymen Yaseen. In this case though there's no need to use any commands they suggested, but rather just set the Node.js tool installer version spec to latest Node version from 11.x.

The exact version of Node.js that got installed and is working was 11.15.0. I didn't have to downgrade the Gulp.

According to this post, you should enable it in XCode.

1. Click on your project in the Project Navigator
2. Open the Info tab
3. Click on the down arrow left to the "App Transport Security Settings"
4. Right click on "App Transport Security Settings" and select Add Row
5. For created row set the key “Allow Arbitrary Loads“, type to boolean and value to YES.

Using Swift 2.1+

 let vc = self.storyboard?.instantiateViewControllerWithIdentifier("settingsVC") as! SettingsViewController
 self.presentViewController(vc, animated: true, completion: nil)

You can access multiple columns by passing a list of column indices to dataFrame.ix.

For example:

>>> df = pandas.DataFrame({
             'a': np.random.rand(5),
             'b': np.random.rand(5),
             'c': np.random.rand(5),
             'd': np.random.rand(5)
         })

>>> df
          a         b         c         d
0  0.705718  0.414073  0.007040  0.889579
1  0.198005  0.520747  0.827818  0.366271
2  0.974552  0.667484  0.056246  0.524306
3  0.512126  0.775926  0.837896  0.955200
4  0.793203  0.686405  0.401596  0.544421

>>> df.ix[:,[1,3]]
          b         d
0  0.414073  0.889579
1  0.520747  0.366271
2  0.667484  0.524306
3  0.775926  0.955200
4  0.686405  0.544421

If you want to replace a simple string and you don't need the abilities of regular expressions, you can just use replace, not replaceAll.

replace replaces each matching substring but does not interpret its argument as a regular expression.

str = xpath.replace(".", "/*/");

I also don't under stand what the "-" means after the 200 140 section of the log

That value corresponds to the referer as described by Joachim. If you see a dash though, that means that there was no referer value to begin with (eg. the user went straight to a specific destination, like if he/she typed a URL in their browser)

I have implemented @satchmorun's suggestion here: https://github.com/andresesfm/angular-underscore-module

To use it:

1. Make sure you have included underscore.js in your project

   <script src="bower_components/underscore/underscore.js">
   

2. Get it:

   bower install angular-underscore-module
   

3. Add angular-underscore-module.js to your main file (index.html)

   <script src="bower_components/angular-underscore-module/angular-underscore-module.js"></script>
   

4. Add the module as a dependency in your App definition

   var myapp = angular.module('MyApp', ['underscore'])
   

5. To use, add as an injected dependency to your Controller/Service and it is ready to use

   angular.module('MyApp').controller('MyCtrl', function ($scope, _) {
   ...
   //Use underscore
   _.each(...);
   ...
   

It's as simple as:

>>> lists = [[1, 2], [3, 4]]
>>> np.array(lists)
array([[1, 2],
       [3, 4]])

So my question is: Is there a way to tell the compiler that a long long int is the also a int64_t, just like long int is?

This is a good question or problem, but I suspect the answer is NO.

Also, a long int may not be a long long int.

# if __WORDSIZE == 64
typedef long int  int64_t;
# else
__extension__
typedef long long int  int64_t;
# endif

I believe this is libc. I suspect you want to go deeper.

In both 32-bit compile with GCC (and with 32- and 64-bit MSVC), the output of the program will be:

int:           0
int64_t:       1
long int:      0
long long int: 1

32-bit Linux uses the ILP32 data model. Integers, longs and pointers are 32-bit. The 64-bit type is a long long.

Microsoft documents the ranges at Data Type Ranges. The say the long long is equivalent to __int64.

However, the program resulting from a 64-bit GCC compile will output:

int:           0
int64_t:       1
long int:      1
long long int: 0

64-bit Linux uses the LP64 data model. Longs are 64-bit and long long are 64-bit. As with 32-bit, Microsoft documents the ranges at Data Type Ranges and long long is still __int64.

There's a ILP64 data model where everything is 64-bit. You have to do some extra work to get a definition for your word32 type. Also see papers like 64-Bit Programming Models: Why LP64?

But this is horribly hackish and does not scale well (actual functions of substance, uint64_t, etc)...

Yeah, it gets even better. GCC mixes and matches declarations that are supposed to take 64 bit types, so its easy to get into trouble even though you follow a particular data model. For example, the following causes a compile error and tells you to use -fpermissive:

#if __LP64__
typedef unsigned long word64;
#else
typedef unsigned long long word64;
#endif

// intel definition of rdrand64_step (http://software.intel.com/en-us/node/523864)
// extern int _rdrand64_step(unsigned __int64 *random_val);

// Try it:
word64 val;
int res = rdrand64_step(&val);

It results in:

error: invalid conversion from `word64* {aka long unsigned int*}' to `long long unsigned int*'

So, ignore LP64 and change it to:

typedef unsigned long long word64;

Then, wander over to a 64-bit ARM IoT gadget that defines LP64 and use NEON:

error: invalid conversion from `word64* {aka long long unsigned int*}' to `uint64_t*'

There is a simplier way, create a form and post it, this runs the risk of resetting the page if the return mime type is something that a browser would open, but for csv and such it's perfect

Example requires underscore and jquery

var postData = {
    filename:filename,
    filecontent:filecontent
};
var fakeFormHtmlFragment = "<form style='display: none;' method='POST' action='"+SAVEAS_PHP_MODE_URL+"'>";
_.each(postData, function(postValue, postKey){
    var escapedKey = postKey.replace("\\", "\\\\").replace("'", "\'");
    var escapedValue = postValue.replace("\\", "\\\\").replace("'", "\'");
    fakeFormHtmlFragment += "<input type='hidden' name='"+escapedKey+"' value='"+escapedValue+"'>";
});
fakeFormHtmlFragment += "</form>";
$fakeFormDom = $(fakeFormHtmlFragment);
$("body").append($fakeFormDom);
$fakeFormDom.submit();

For things like html, text and such, make sure the mimetype is some thing like application/octet-stream

php code

<?php
/**
 * get HTTP POST variable which is a string ?foo=bar
 * @param string $param
 * @param bool $required
 * @return string
 */
function getHTTPPostString ($param, $required = false) {
    if(!isset($_POST[$param])) {
        if($required) {
            echo "required POST param '$param' missing";
            exit 1;
        } else {
            return "";
        }
    }
    return trim($_POST[$param]);
}

$filename = getHTTPPostString("filename", true);
$filecontent = getHTTPPostString("filecontent", true);

header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$filename\"");
echo $filecontent;

If you are in a JEE7 environment, you must have a decent implementation of JAXRS hanging around, which would allow you to easily make asynchronous HTTP request using its client API.

This would looks like this:

public class Main {

    public static Future<Response> getAsyncHttp(final String url) {
        return ClientBuilder.newClient().target(url).request().async().get();
    }

    public static void main(String ...args) throws InterruptedException, ExecutionException {
        Future<Response> response = getAsyncHttp("http://www.nofrag.com");
        while (!response.isDone()) {
            System.out.println("Still waiting...");
            Thread.sleep(10);
        }
        System.out.println(response.get().readEntity(String.class));
    }
}

Of course, this is just using futures. If you are OK with using some more libraries, you could take a look at RxJava, the code would then look like:

public static void main(String... args) {
    final String url = "http://www.nofrag.com";
    rx.Observable.from(ClientBuilder.newClient().target(url).request().async().get(String.class), Schedulers
            .newThread())
            .subscribe(
                    next -> System.out.println(next),
                    error -> System.err.println(error),
                    () -> System.out.println("Stream ended.")
            );
    System.out.println("Async proof");
}

And last but not least, if you want to reuse your async call, you might want to take a look at Hystrix, which - in addition to a bazillion super cool other stuff - would allow you to write something like this:

For example:

public class AsyncGetCommand extends HystrixCommand<String> {

    private final String url;

    public AsyncGetCommand(final String url) {
        super(Setter.withGroupKey(HystrixCommandGroupKey.Factory.asKey("HTTP"))
                .andCommandPropertiesDefaults(HystrixCommandProperties.Setter()
                        .withExecutionIsolationThreadTimeoutInMilliseconds(5000)));
        this.url = url;
    }

    @Override
    protected String run() throws Exception {
        return ClientBuilder.newClient().target(url).request().get(String.class);
    }

 }

Calling this command would look like:

public static void main(String ...args) {
    new AsyncGetCommand("http://www.nofrag.com").observe().subscribe(
            next -> System.out.println(next),
            error -> System.err.println(error),
            () -> System.out.println("Stream ended.")
    );
    System.out.println("Async proof");
}

PS: I know the thread is old, but it felt wrong that no ones mentions the Rx/Hystrix way in the up-voted answers.

I was just having this issue with my own program. I turned out that the value I was searching for was not in my reference table. I fixed my reference table, and then the error went away.

The /sys filesystem should contain plenty information for your quest. My system (2.6.32-40-generic #87-Ubuntu) suggests:

/sys/class/tty

Which gives you descriptions of all TTY devices known to the system. A trimmed down example:

# ll /sys/class/tty/ttyUSB*
lrwxrwxrwx 1 root root 0 2012-03-28 20:43 /sys/class/tty/ttyUSB0 -> ../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.0/ttyUSB0/tty/ttyUSB0/
lrwxrwxrwx 1 root root 0 2012-03-28 20:44 /sys/class/tty/ttyUSB1 -> ../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3/2-1.3:1.0/ttyUSB1/tty/ttyUSB1/

Following one of these links:

# ll /sys/class/tty/ttyUSB0/
insgesamt 0
drwxr-xr-x 3 root root    0 2012-03-28 20:43 ./
drwxr-xr-x 3 root root    0 2012-03-28 20:43 ../
-r--r--r-- 1 root root 4096 2012-03-28 20:49 dev
lrwxrwxrwx 1 root root    0 2012-03-28 20:43 device -> ../../../ttyUSB0/
drwxr-xr-x 2 root root    0 2012-03-28 20:49 power/
lrwxrwxrwx 1 root root    0 2012-03-28 20:43 subsystem -> ../../../../../../../../../../class/tty/
-rw-r--r-- 1 root root 4096 2012-03-28 20:43 uevent

Here the dev file contains this information:

# cat /sys/class/tty/ttyUSB0/dev
188:0

This is the major/minor node. These can be searched in the /dev directory to get user-friendly names:

# ll -R /dev |grep "188, *0"
crw-rw----   1 root dialout 188,   0 2012-03-28 20:44 ttyUSB0

The /sys/class/tty dir contains all TTY devices but you might want to exclude those pesky virtual terminals and pseudo terminals. I suggest you examine only those which have a device/driver entry:

# ll /sys/class/tty/*/device/driver
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS0/device/driver -> ../../../bus/pnp/drivers/serial/
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS1/device/driver -> ../../../bus/pnp/drivers/serial/
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS2/device/driver -> ../../../bus/platform/drivers/serial8250/
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS3/device/driver -> ../../../bus/platform/drivers/serial8250/
lrwxrwxrwx 1 root root 0 2012-03-28 20:43 /sys/class/tty/ttyUSB0/device/driver -> ../../../../../../../../bus/usb-serial/drivers/ftdi_sio/
lrwxrwxrwx 1 root root 0 2012-03-28 21:15 /sys/class/tty/ttyUSB1/device/driver -> ../../../../../../../../bus/usb-serial/drivers/ftdi_sio/

Actually using 100% will not make the image bigger if the image is smaller than the div size you specified. You need to set one of the dimensions, height or width in order to have all images fill the space. In my experience it's better to have the height set so each row is the same size, then all items wrap to next line properly. This will produce an output similar to fotolia.com (stock image website)

with css:

parent {
   width: 42px; /* I took the width from your post and placed it in css */
   height: 42px;
}

/* This will style any <img> element in .parent div */
.parent img {
   height: 42px;
}

without:

<div style="height:42px;width:42px">
    <img style="height:42px" src="http://someimage.jpg">
</div>

Use Set in Python

>>> a = [2,4]
>>> b = [1,4,3]
>>> set(a) - set(b)
set([2])

Don't forget to check whether the string is empty or null. If we forget checking null or empty then we would get NullPointerException or StringIndexOutOfBoundException if a given String is null or empty.

public class StartWithUpperCase{

        public static void main(String[] args){

            String str1 = ""; //StringIndexOfBoundException if 
                              //empty checking not handled
            String str2 = null; //NullPointerException if 
                                //null checking is not handled.
            String str3 = "Starts with upper case";
            String str4 = "starts with lower case";

            System.out.println(startWithUpperCase(str1)); //false
            System.out.println(startWithUpperCase(str2)); //false
            System.out.println(startWithUpperCase(str3)); //true
            System.out.println(startWithUpperCase(str4)); //false



        }

        public static boolean startWithUpperCase(String givenString){

            if(null == givenString || givenString.isEmpty() ) return false;
            else return (Character.isUpperCase( givenString.codePointAt(0) ) );
        }

    }

You can build it with list comprehension like this:

>>> dict((i, range(int(i), int(i) + 2)) for i in ['1', '2'])
{'1': [1, 2], '2': [2, 3]}

And for the second part of your question use defaultdict

>>> from collections import defaultdict
>>> s = [('yellow', 1), ('blue', 2), ('yellow', 3), ('blue', 4), ('red', 1)]
>>> d = defaultdict(list)
>>> for k, v in s:
        d[k].append(v)

>>> d.items()
[('blue', [2, 4]), ('red', [1]), ('yellow', [1, 3])]

I know this is an old question, but the following should work if you don't need the month name at the DB level:

  SELECT EXTRACT(YEAR_MONTH FROM summaryDateTime) summary_year_month 
    FROM trading_summary  
GROUP BY summary_year_month;

See EXTRACT function docs

You will probably find this to be better performing.. and if you are building a JSON object in the application layer, you can do the formatting/ordering as you run through the results.

N.B. I wasn't aware you could add DESC to a GROUP BY clause in MySQL, perhaps you are missing an ORDER BY clause:

  SELECT EXTRACT(YEAR_MONTH FROM summaryDateTime) summary_year_month 
    FROM trading_summary  
GROUP BY summary_year_month
ORDER BY summary_year_month DESC;

For ASP.NET try this:

<script type="text/javascript">
    Sys.Application.add_load(function() { ... });
</script>

This appears to work on page load and on update panel load

Please find the full discussion here.

You can also use below just simple to check:

If startDate <> Nothing Then
your logic
End If

It will check that the startDate variable of DateTime datatype is null or not.

My Resolution,

In my case, I have created a model file and kept it blank,

so when I imported it to other model, It gives me error. so write the definition when you create a model typescript file.

There is an issue with downloading and installing Python 3.6. Unchecking pip in the installation prevents the issue. So pip is not given in every installation.

num = int(input('Size of elements : '))
arr = list()

for i in range(num) :
  ele  = int(input())
  arr.append(ele)

print(arr)

SELECT * FROM ( 
    SELECT  2 AS RTYPE,V.ID AS VTYPE, DATE_FORMAT(ENTDT, ''%d-%m-%Y'')  AS ENTDT,V.NAME AS VOUCHERTYPE,VOUCHERNO,ROUND(IF((DR_CR)>0,(DR_CR),0),0) AS DR ,ROUND(IF((DR_CR)<0,(DR_CR)*-1,0),2) AS CR ,ROUND((dr_cr),2) AS BALAMT, IF(d.narr IS NULL OR d.narr='''',t.narration,d.narr) AS NARRATION

Say, you want to sort by 'created_on' field, then you can do like this,

.sort('{}'.format('created_on'), 1 if sort_type == 'asc' else -1)

<?php
    header("Location: index.html");
?>

Just make sure nothing is actually written to the page prior to this code, or it won't work.

You are iterating through an undefined value, ie, com property of the Array's object, you should iterate through the array itself:

$.each(obj, function(key,value) {
   // here `value` refers to the objects 
});

Also note that jQuery intelligently tries to parse the sent JSON, probably you don't need to parse the response. If you are using $.ajax(), you can set the dataType to json which tells jQuery parse the JSON for you.

If it still doesn't work, check the browser's console for troubleshooting.

Try something like this:

var node=document.createElement("LI");
var textnode=document.createTextNode(firstname);
node.appendChild(textnode);
document.getElementById("demo").appendChild(node);

Fiddle: http://jsfiddle.net/FlameTrap/3jDZd/

private <A, B> Map<B, A> invertMap(Map<A, B> map) {
    Map<B, A> reverseMap = new HashMap<>();
    for (Map.Entry<A, B> entry : map.entrySet()) {
        reverseMap.put(entry.getValue(), entry.getKey());
    }
    return reverseMap;
}

It's important to remember that put replaces the value when called with the same key. So if you map has two keys with the same value only one of them will exist in the inverted map.

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

if it's not a foreign key field, not using empty strings could save you some trouble. only allow nulls if you'll take null to mean something different than an empty string. for example if you have a password field, a null value could indicate that a new user has not created his password yet while an empty varchar could indicate a blank password. for a field like "address2" allowing nulls can only make life difficult. things to watch out for include null references and unexpected results of = and <> operators mentioned by Vagif Verdi, and watching out for these things is often unnecessary programmer overhead.

edit: if performance is an issue see this related question: Nullable vs. non-null varchar data types - which is faster for queries?

For completeness, we should mention PEP3119 where ABC was introduced and compared with interfaces, and original Talin's comment.

The abstract class is not perfect interface:

• belongs to the inheritance hierarchy
• is mutable

But if you consider writing it your own way:

def some_function(self):
     raise NotImplementedError()

interface = type(
    'your_interface', (object,),
    {'extra_func': some_function,
     '__slots__': ['extra_func', ...]
     ...
     '__instancecheck__': your_instance_checker,
     '__subclasscheck__': your_subclass_checker
     ...
    }
)

ok, rather as a class
or as a metaclass
and fighting with python to achieve the immutable object
and doing refactoring
...

you'll quite fast realize that you're inventing the wheel to eventually achieve abc.ABCMeta

abc.ABCMeta was proposed as a useful addition of the missing interface functionality, and that's fair enough in a language like python.

Certainly, it was able to be enhanced better whilst writing version 3, and adding new syntax and immutable interface concept ...

Conclusion:

The abc.ABCMeta IS "pythonic" interface in python

These answers were helpful, but I wanted to share my answer with both the app.config part and the c# code part, so there is less guessing for the next person.

<log4net>
  <appender name="SomeName" type="log4net.Appender.RollingFileAppender">
    <file value="c:/Console.txt" />
    <appendToFile value="true" />
    <rollingStyle value="Composite" />
    <datePattern value="yyyyMMdd" />
    <maxSizeRollBackups value="10" />
    <maximumFileSize value="1MB" />
  </appender>
  <appender name="Summary" type="log4net.Appender.FileAppender">
    <file value="SummaryFile.log" />
    <appendToFile value="true" />
  </appender>
  <root>
    <level value="ALL" />
    <appender-ref ref="SomeName" />
  </root>
  <logger additivity="false" name="Summary">
    <level value="DEBUG"/>
    <appender-ref ref="Summary" />
  </logger>
</log4net>

Then in code:

ILog Log = LogManager.GetLogger("SomeName");
ILog SummaryLog = LogManager.GetLogger("Summary");
Log.DebugFormat("Processing");
SummaryLog.DebugFormat("Processing2"));

Here c:/Console.txt will contain "Processing" ... and \SummaryFile.log will contain "Processing2"

Please incre max_iter to 10000 as default value is 1000. Possibly, increasing no. of iterations will help algorithm to converge. For me it converged and solver was -'lbfgs'

log_reg = LogisticRegression(solver='lbfgs',class_weight='balanced', max_iter=10000)

Theres no a reason to let all that console.log all over your project in prod enviroment... If you want to do it on the proper way, add UglifyJS2 to your deployment process using "drop_console" option.

I was facing the same issue because I was using Lombok @Data annotation that was creating toString and hashcode methods in class files, so I removed @Data annotation and used specific @Gettter @Setter annotation that fixed my issue.

we should use @Data only when we need all @ToString, @EqualsAndHashCode, @Getter on all fields, and @Setter on all non-final fields, and @RequiredArgsConstructor.

I got this after saving the JSON file using Notepad2, so I had to open it with Notepad++ and then say "Convert to UTF-8". Then it worked.

My awk-less, sed-less, Perl-less, Python-less POSIX-compliant alternative:

find . -type f | rev | cut -d. -f1 | rev  | tr '[:upper:]' '[:lower:]' | sort | uniq --count | sort -rn

The trick is that it reverses the line and cuts the extension at the beginning.
It also converts the extensions to lower case.

Example output:

   1036 png
    610 mp4

I created a small hackMD to install cocoapods on MacOS 10.15 (Catalina) and 11 (Big Sur)

https://hackmd.io/@sBJPlhRESGqCKCqV8ZjP1A/S1UY3W7HP

Installing Cocoapods on MacOS Catalina(MacOS 10.15.X) and Big Sur (MacOS 11)

1. Make sure you have xcode components are installed.

2. Download 'Command Line Tools' (about 500MB) directly from this link (Requires you to have apple account) https://developer.apple.com/downloads/index.action

3. Install the downloaded file

4. Click on Install

5. Install COCOAPODS files in terminal sudo gem install -n /usr/local/bin cocoapods

If you only want to match "" as an empty string

WHERE DATALENGTH(COLUMN) > 0 

If you want to count any string consisting entirely of spaces as empty

WHERE COLUMN <> '' 

Both of these will not return NULL values when used in a WHERE clause. As NULL will evaluate as UNKNOWN for these rather than TRUE.

CREATE TABLE T 
  ( 
     C VARCHAR(10) 
  ); 

INSERT INTO T 
VALUES      ('A'), 
            (''),
            ('    '), 
            (NULL); 

SELECT * 
FROM   T 
WHERE  C <> ''

Returns just the single row A. I.e. The rows with NULL or an empty string or a string consisting entirely of spaces are all excluded by this query.

SQL Fiddle

You can do it like this:

postData[postData.length] = { name: "variable_name", value: variable_value };

Just to add yet another answer to an old question... People have mentioned the @EnableWebMvc will prevent WebMvcAutoConfiguration from loading, which is the code responsible for creating the static resource handlers. There are other conditions that will prevent WebMvcAutoConfiguration from loading as well. Clearest way to see this is to look at the source:

https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration.java#L139-L141

In my case, I was including a library that had a class that was extending from WebMvcConfigurationSupport which is a condition that will prevent the autoconfiguration:

@ConditionalOnMissingBean(WebMvcConfigurationSupport.class)

It's important to never extend from WebMvcConfigurationSupport. Instead, extend from WebMvcConfigurerAdapter.

UPDATE: The proper way to do this in 5.x is to implement WebMvcConfigurer

logging.basicConfig() can take a keyword argument handlers since Python 3.3, which simplifies logging setup a lot, especially when setting up multiple handlers with the same formatter:

handlers – If specified, this should be an iterable of already created handlers to add to the root logger. Any handlers which don’t already have a formatter set will be assigned the default formatter created in this function.

The whole setup can therefore be done with a single call like this:

import logging

logging.basicConfig(
    level=logging.INFO,
    format="%(asctime)s [%(levelname)s] %(message)s",
    handlers=[
        logging.FileHandler("debug.log"),
        logging.StreamHandler()
    ]
)

(Or with import sys + StreamHandler(sys.stdout) per original question's requirements – the default for StreamHandler is to write to stderr. Look at LogRecord attributes if you want to customize the log format and add things like filename/line, thread info etc.)

The setup above needs to be done only once near the beginning of the script. You can use the logging from all other places in the codebase later like this:

logging.info('Useful message')
logging.error('Something bad happened')
...

Note: If it doesn't work, someone else has probably already initialized the logging system differently. Comments suggest doing logging.root.handlers = [] before the call to basicConfig().

Sometime only this helps:

View child = parent.findViewById(R.id.btnMoreText);
    child.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            View parent = (View) v.getParent();
            parent.performClick();
        }
    });

Another variant, works not always:

child.setOnClickListener(null);

@serenn's answer above is still a great one for the case of UINavigationControllers. However, for swift 3 the childViewController functions have been changed to vars. So the UINavigationController extension code should be:

override open var childViewControllerForStatusBarStyle: UIViewController? {
  return topViewController
}

override open var childViewControllerForStatusBarHidden: UIViewController? {
  return topViewController
}

And then in the view controller that should dictate the status bar style:

override var preferredStatusBarStyle: UIStatusBarStyle {
   return .lightContent
}

You can execute pip module for a specific python version using the corresponding python:

Python 2.6:

python2.6 -m pip install beautifulsoup4

Python 2.7

python2.7 -m pip install beautifulsoup4

None of the above solutions alone worked for me. On Windows 7 this worked:

Install Rapid Environment Editor and remove any entries for node, npm, angular-cli or @angular/cli

Uninstall node.js and reinstall. Run Rapid Environment Editor again and make sure node.js and npm are in your System or User path. Uninstall any existing ng versions with:

npm uninstall -g angular-cli

npm uninstall -g @angular/cli

npm cache clean

Delete the C:\Users\YOU\AppData\Roaming\npm\node_modules\@angular folder.

Reboot, then, finally, run:

npm install -g @angular/cli

Then hold your breath and run ng -v. If you're lucky, you'll get some love. Hold your breath henceforward every time you run the ng command, because 'command not found' has magically reappeared for me several times after ng was running fine and I thought the problem was solved.

It's easy to believe that deleting the whole Subversion repository requires "informing" Subversion that you're going to delete the repository. But Subversion only cares about managing a repository once it's created, not whether the repository exists or not ( if that makes sense ). It goes like this: the Subversion tools and commands are not adversely affected by just deleting your repository directory with the regular operating system utilities (like rm -R). A repository directory is not the same thing as an installed program directory, where deleting a program without uninstalling it might leave behind erratic config files or other dependencies. A repository is 100% self-contained in its directory, and deleting it is harmless (besides losing your project history). You just clean the slate to create a new Subversion repository and import your next project.

Please make sure that your file name should not be panda.py or pd.py. Also, make sure that panda is there in your Lib/site-packages directory, if not that you need to install panda using below command line:

pip install pandas

if you work with proxy then try calling below in command prompt:

python.exe -m pip install pandas --proxy="YOUR_PROXY_IP:PORT"

Teocci solution is as simple as it can be, thus, no need to add any CSS, just add class="fas" for Font Awesome 5, since it adds proper CSS font declaration to the element.

I've had the same error as you have and it turned out that there was nothing wrong with the code. The problem was that the webserver was sending the wrong Content-Type header.

Try wireshark or something similar to see what content-type the webserver is sending.

With API 8 and greater, the location of the SD card has changed. @fiXedd's answer is good, but for safer code, you should use Environment.getExternalStorageState() to check if the media is available. Then you can use getExternalFilesDir() to navigate to the directory you want (assuming you're using API 8 or greater).

You can read more in the SDK documentation.

Default interpreters from Microsoft are done in a way, that causes them exit when they reach EOF. If rake is another batch file, command interpreter switches to it and exits when rake interpretation is finished. To prevent this write:

@echo off
cls
call rake
pause

IMHO, call operator will lauch another instance of intepretator thereby preventing the current one interpreter from switching to another input file.

The sp_xml_preparedocument stored procedure will parse the XML and the OPENXML rowset provider will show you a relational view of the XML data.

Flyway changed the way it calculates the checksums from version 3 to version 5. You can re-calculate the checksums. Since the Flyway plugin doesn't properly read the Spring datasource properties, you have to manually specify them on the command line (or one of the other various ways Flyway accepts).

mvn flyway:repair -Dflyway.user=root -Dflyway.password= -Dflyway.url=jdbc:mysql://localhost:3306/mydatabase -Dflyway.table=schema_version

Flyway also changed the table it stores the checksums, so you also have to specify flyway-table=schema_version to use your old table, or else it will give you a warning (and probably an error in version 6).

Assuming that you are using a spfile to start the database

alter system set open_cursors = 1000 scope=both;

If you are using a pfile instead, you can change the setting for the running instance

alter system set open_cursors = 1000 

You would also then need to edit the parameter file to specify the new open_cursors setting. It would generally be a good idea to restart the database shortly thereafter to make sure that the parameter file change works as expected (it's highly annoying to discover months later the next time that you reboot the database that some parameter file change than no one remembers wasn't done correctly).

I'm also hoping that you are certain that you actually need more than 300 open cursors per session. A large fraction of the time, people that are adjusting this setting actually have a cursor leak and they are simply trying to paper over the bug rather than addressing the root cause.

After hacking around with this a bit, I found the best way was to use the setSelectionRange function if the browser supports it; if not, revert to using the method in Mike Berrow's answer (i.e. replace the value with itself).

I'm also setting scrollTop to a high value in case we're in a vertically-scrollable textarea. (Using an arbitrary high value seems more reliable than $(this).height() in Firefox and Chrome.)

I've made it is as a jQuery plugin. (If you're not using jQuery I trust you can still get the gist easily enough.)

I've tested in IE6, IE7, IE8, Firefox 3.5.5, Google Chrome 3.0, Safari 4.0.4, Opera 10.00.

It's available on jquery.com as the PutCursorAtEnd plugin. For your convenience, the code for release 1.0 is as follows:

// jQuery plugin: PutCursorAtEnd 1.0
// http://plugins.jquery.com/project/PutCursorAtEnd
// by teedyay
//
// Puts the cursor at the end of a textbox/ textarea

// codesnippet: 691e18b1-f4f9-41b4-8fe8-bc8ee51b48d4
(function($)
{
    jQuery.fn.putCursorAtEnd = function()
    {
    return this.each(function()
    {
        $(this).focus()

        // If this function exists...
        if (this.setSelectionRange)
        {
        // ... then use it
        // (Doesn't work in IE)

        // Double the length because Opera is inconsistent about whether a carriage return is one character or two. Sigh.
        var len = $(this).val().length * 2;
        this.setSelectionRange(len, len);
        }
        else
        {
        // ... otherwise replace the contents with itself
        // (Doesn't work in Google Chrome)
        $(this).val($(this).val());
        }

        // Scroll to the bottom, in case we're in a tall textarea
        // (Necessary for Firefox and Google Chrome)
        this.scrollTop = 999999;
    });
    };
})(jQuery);

Or you can do this:

MyString[0];

Swift "Button factory" extension for UIButton (and while we're at it) also for UILabel like so:

extension UILabel
{
// A simple UILabel factory function
// returns instance of itself configured with the given parameters

// use example (in a UIView or any other class that inherits from UIView):

//   addSubview(   UILabel().make(     x: 0, y: 0, w: 100, h: 30,
//                                   txt: "Hello World!",
//                                 align: .center,
//                                   fnt: aUIFont,
//                              fntColor: UIColor.red)                 )
//

func make(x: CGFloat, y: CGFloat, w: CGFloat, h: CGFloat,
          txt: String,
          align: NSTextAlignment,

    adjustsFontSizeToFitWidth = true
    textAlignment = align
    text = txt
    textColor = fntColor
    font = fnt
    return self
}
// Of course, you can make more advanced factory functions etc.
// Also one could subclass UILabel, but this seems to be a     convenient case for an extension.
}


extension UIButton
{
// UIButton factory returns instance of UIButton
//usage example:

// addSubview(UIButton().make(x: btnx, y:100, w: btnw, h: btnh,
// title: "play", backColor: .red,
// target: self,
// touchDown: #selector(play), touchUp: #selector(stopPlay)))


func make(   x: CGFloat,y: CGFloat,
             w: CGFloat,h: CGFloat,
                  title: String, backColor: UIColor,
                  target: UIView,
                  touchDown:  Selector,
                  touchUp:    Selector ) -> UIButton
{
    frame = CGRect(x: x, y: y, width: w, height: h)
    backgroundColor = backColor
    setTitle(title, for: .normal)

    addTarget(target, action: touchUp  , for: .touchUpInside)
    addTarget(target, action: touchUp  , for: .touchUpOutside)

    return self
}
}

If you want to overwrite the previous line (rather than continually adding to it), you can combine \r with print(), at the end of the print statement. For example,

from time import sleep

for i in xrange(0, 10):
    print("\r{0}".format(i)),
    sleep(.5)

print("...DONE!")

will count 0 to 9, replacing the old number in the console. The "...DONE!" will print on the same line as the last counter, 9.

In your case for the OP, this would allow the console to display percent complete of the install as a "progress bar", where you can define a begin and end character position, and update the markers in between.

print("Installing |XXXXXX              | 30%"),

Add a date of modification of js file at the end of your URL. With PHP it would look something like this:

echo '<script type="text/javascript" src="js/something.js?' . filemtime('js/something.js') . '"></script>';

When your script will be reloaded every time you update it.

Firstly, you should use randrange(0,1000) or randint(0,999), not randint(0,1000). The upper limit of randint is inclusive.

For efficiently, randint is simply a wrapper of randrange which calls random, so you should just use random. Also, use xrange as the argument to sample, not range.

You could use

[a for a in sample(xrange(1000),1000) for _ in range(10000/1000)]

to generate 10,000 numbers in the range using sample 10 times.

(Of course this won't beat NumPy.)

$ python2.7 -m timeit -s 'from random import randrange' '[randrange(1000) for _ in xrange(10000)]'
10 loops, best of 3: 26.1 msec per loop

$ python2.7 -m timeit -s 'from random import sample' '[a%1000 for a in sample(xrange(10000),10000)]'
100 loops, best of 3: 18.4 msec per loop

$ python2.7 -m timeit -s 'from random import random' '[int(1000*random()) for _ in xrange(10000)]' 
100 loops, best of 3: 9.24 msec per loop

$ python2.7 -m timeit -s 'from random import sample' '[a for a in sample(xrange(1000),1000) for _ in range(10000/1000)]'
100 loops, best of 3: 3.79 msec per loop

$ python2.7 -m timeit -s 'from random import shuffle
> def samplefull(x):
>   a = range(x)
>   shuffle(a)
>   return a' '[a for a in samplefull(1000) for _ in xrange(10000/1000)]'
100 loops, best of 3: 3.16 msec per loop

$ python2.7 -m timeit -s 'from numpy.random import randint' 'randint(1000, size=10000)'
1000 loops, best of 3: 363 usec per loop

But since you don't care about the distribution of numbers, why not just use:

development refers to the branch you want to pull from. If you want to pull from master branch then type this one.

git pull origin master

Unidecode is the correct answer for this. It transliterates any unicode string into the closest possible representation in ascii text.

Example:

accented_string = u'Málaga'
# accented_string is of type 'unicode'
import unidecode
unaccented_string = unidecode.unidecode(accented_string)
# unaccented_string contains 'Malaga'and is of type 'str'
