At least in Node v8.9.1, you can just do

var json_data = require('/path/to/local/file.json');

and access all the elements of the JSON object.

You can load local CSV file to Hive only if:

1. You are doing it from one of the Hive cluster nodes.
2. You installed Hive client on non-cluster node and using hive or beeline for upload.

Add-on software packages.

See http://www.pathname.com/fhs/2.2/fhs-3.12.html for details.

Also described at Wikipedia.

Its use dates back at least to the late 1980s, when it was a standard part of System V UNIX. These days, it's also seen in Linux, Solaris (which is SysV), OSX Cygwin, etc. Other BSD unixes (FreeBSD, NetBSD, etc) tend to follow other rules, so you don't usually see BSD systems with an /opt unless they're administered by someone who is more comfortable in other environments.

private Object actuallyT;

public <T> List<T> magicalListGetter(Class<T> klazz) {
    List<T> list = new ArrayList<>();
    list.add(klazz.cast(actuallyT));
    try {
        list.add(klazz.getConstructor().newInstance()); // If default constructor
    } ...
    return list;
}

One can give a generic type parameter to a method too. You have correctly deduced that one needs the correct class instance, to create things (klazz.getConstructor().newInstance()).

SELECT *
FROM logs
WHERE pw='correct'
  AND CASE
          WHEN id<800 THEN success=1
          ELSE 1=1
      END
  AND YEAR(TIMESTAMP)=2011

If you want user readable data but still detailed, you can use platform.platform()

>>> import platform
>>> platform.platform()
'Linux-3.3.0-8.fc16.x86_64-x86_64-with-fedora-16-Verne'

platform also has some other useful methods:

>>> platform.system()
'Windows'
>>> platform.release()
'XP'
>>> platform.version()
'5.1.2600'

Here's a few different possible calls you can make to identify where you are

import platform
import sys

def linux_distribution():
  try:
    return platform.linux_distribution()
  except:
    return "N/A"

print("""Python version: %s
dist: %s
linux_distribution: %s
system: %s
machine: %s
platform: %s
uname: %s
version: %s
mac_ver: %s
""" % (
sys.version.split('\n'),
str(platform.dist()),
linux_distribution(),
platform.system(),
platform.machine(),
platform.platform(),
platform.uname(),
platform.version(),
platform.mac_ver(),
))

The outputs of this script ran on a few different systems (Linux, Windows, Solaris, MacOS) and architectures (x86, x64, Itanium, power pc, sparc) is available here: https://github.com/hpcugent/easybuild/wiki/OS_flavor_name_version

e.g. Solaris on sparc gave:

Python version: ['2.6.4 (r264:75706, Aug  4 2010, 16:53:32) [C]']
dist: ('', '', '')
linux_distribution: ('', '', '')

version: Generic_122300-60
mac_ver: ('', ('', '', ''), '')

Based on bnkdev's answer I modified Narayana's Code to search all columns even numeric ones.

It'll run slower, but this version actually finds all matches not just those found in text columns.

I can't thank this guy enough. Saved me days of searching by hand!

The exact wording of the latest published standard (C++14) is:

An implementation shall allow both

• a function of () returning int and

• a function of (int, pointer to pointer to char) returning int

as the type of main.

This makes it clear that alternative spellings are permitted so long as the type of main is the type int() or int(int, char**). So the following are also permitted:

• int main(void)
• auto main() -> int
• int main ( )
• signed int main()
• typedef char **a; typedef int b, e; e main(b d, a c)

Use the below command to copy data from CSV in a single line without casting and changing your datatype. Please replace "NULL" by your string which creating error in copy data

copy table_name from 'path to csv file' (format csv, null "NULL", DELIMITER ',', HEADER);

Your css is fine, but I think it's not applying on divs. Just write simple class name and then try. You can check it at Jsfiddle.

.left {
  float: left;
  width: 125px;
  text-align: right;
  margin: 2px 10px;
  display: inline;
}

.right {
  float: left;
  text-align: left;
  margin: 2px 10px;
  display: inline;
}

Let me share an example which I developed with BS4, thymeleaf and Spring boot.

I am using two SELECTs, where the second ("subtopic") gets filled by an AJAX call based on the selection of the first("topic").

First, the thymeleaf snippet:

 <div class="form-group">
     <label th:for="topicId" th:text="#{label.topic}">Topic</label>
     <select class="custom-select"
             th:id="topicId" th:name="topicId"
             th:field="*{topicId}"
             th:errorclass="is-invalid" required>
         <option value="" selected
                 th:text="#{option.select}">Select
         </option>
         <optgroup th:each="topicGroup : ${topicGroups}"
                   th:label="${topicGroup}">
             <option th:each="topicItem : ${topics}"
                     th:if="${topicGroup == topicItem.grp} "
                     th:value="${{topicItem.baseIdentity.id}}"
                     th:text="${topicItem.name}"
                     th:selected="${{topicItem.baseIdentity.id==topicId}}">
             </option>
         </optgroup>
         <option th:each="topicIter : ${topics}"
                 th:if="${topicIter.grp == ''} "
                 th:value="${{topicIter.baseIdentity.id}}"
                 th:text="${topicIter.name}"
                 th:selected="${{topicIter.baseIdentity?.id==topicId}}">
         </option>
     </select>
     <small id="topicHelp" class="form-text text-muted"
            th:text="#{label.topic.tt}">select</small>
</div><!-- .form-group -->

<div class="form-group">
    <label for="subtopicsId" th:text="#{label.subtopicsId}">subtopics</label>
    <select class="custom-select"
            id="subtopicsId" name="subtopicsId"
            th:field="*{subtopicsId}"
            th:errorclass="is-invalid" multiple="multiple">
        <option value="" disabled
                th:text="#{option.multiple.optional}">Select
        </option>
        <option th:each="subtopicsIter : ${subtopicsList}"
                th:value="${{subtopicsIter.baseIdentity.id}}"
                th:text="${subtopicsIter.name}">
        </option>
    </select>
    <small id="subtopicsHelp" class="form-text text-muted"
           th:unless="${#fields.hasErrors('subtopicsId')}"
           th:text="#{label.subtopics.tt}">select</small>
    <small id="subtopicsIdError" class="invalid-feedback"
           th:if="${#fields.hasErrors('subtopicsId')}"
           th:errors="*{subtopicsId}">Errors</small>
</div><!-- .form-group -->

I am iterating over a list of topics that is stored in the model context, showing all groups with their topics, and after that all topics that do not have a group. BaseIdentity is an @Embedded composite key BTW.

Now, here's the jQuery that handles changes:

$('#topicId').change(function () {
    selectedOption = $(this).val();
    if (selectedOption === "") {
        $('#subtopicsId').prop('disabled', 'disabled').val('');
        $("#subtopicsId option").slice(1).remove(); // keep first
    } else {
        $('#subtopicsId').prop('disabled', false)
        var orig = $(location).attr('origin');
        var url = orig + "/getsubtopics/" + selectedOption;
        $.ajax({
            url: url,
           success: function (response) {
                  var len = response.length;
                    $("#subtopicsId option[value!='']").remove(); // keep first 
                    for (var i = 0; i < len; i++) {
                        var id = response[i]['baseIdentity']['id'];
                        var name = response[i]['name'];
                        $("#subtopicsId").append("<option value='" + id + "'>" + name + "</option>");
                    }
                },
                error: function (e) {
                    console.log("ERROR : ", e);
                }
        });
    }
}).change(); // and call it once defined

The initial call of change() makes sure it will be executed on page re-load or if a value has been preselected by some initialization in the backend.

BTW: I am using "manual" form validation (see "is-valid"/"is-invalid"), because I (and users) didn't like that BS4 marks non-required empty fields as green. But that's byond scope of this Q and if you are interested then I can post it also.

You can by hardcoding the sequence, like so:

li, li + li + li, li + li + li + li + li {
  background-color: black;
}

li + li, li + li + li + li {
  background-color: white;
}

if you have a dataframe where some columns are numeric and some are other (character or factor) and you only want to do the correlations for the numeric columns, you could do the following:

set.seed(10)

x = as.data.frame(matrix(rnorm(100), ncol = 10))
x$L1 = letters[1:10]
x$L2 = letters[11:20]

cor(x)

Error in cor(x) : 'x' must be numeric

but

cor(x[sapply(x, is.numeric)])

Spring.Net is quite solid, but the documentation took some time to wade through. Autofac is good, and while .Net 2.0 is supported, you need VS 2008 to compile it, or else use the command line to build your app.

Try this:

<?php
  $date = date_parse('July');
  var_dump($date['month']);
?>

This blog post explains very well:

(just replace 9.X by your version. e.g: 9.6)

A. If installed PostgreSQL with homebrew, enter brew uninstall postgresql

B. If you used the EnterpriseDB installer, follow the following step.

Run the uninstaller on terminal window: sudo /Library/PostgreSQL/9.X/uninstall-postgresql.app/Contents/MacOS/installbuilder.sh

C. If installed with Postgres Installer, do:

open /Library/PostgreSQL/9.X/uninstall-postgresql.app

Remove the PostgreSQL and data folders. The Wizard will notify you that these were not removed.

sudo rm -rf /Library/PostgreSQL

Remove the ini file:

sudo rm /etc/postgres-reg.ini

Remove the PostgreSQL user using System Preferences -> Users & Groups.

Unlock the settings panel by clicking on the padlock and entering your password. Select the PostgreSQL user and click on the minus button. Restore your shared memory settings: sudo rm /etc/sysctl.conf

Here's how you can change the android sdk path in Android studio:

1. Open your required android project in Android studio
2. Click on the main project folder and press F4
3. Now click on "SDKs" under Platform Settings (Left hand side of the dialog box)
4. You should now see a plus sign on the top, click it and choose "Android SDK"
5. Now you would be asked to choose the required SDK folder
6. Select the required build target(if necessary) and click "ok"
7. Now you should see the new entry in the list of SDKs
8. Click "Modules" under Project Settings
9. Select your project folder and in the Dropdown for "Module SDK", select the new SDK entry and click "apply"
10. Now click "OK" and your done.

Note: If changes do not take effect, restarting android studio should fix the problem.

I used this one is working for me. One thing needs to be consider that what appcompat version you are using. I am using appcompat-v7:26.+ so this is working for me.

implementation 'com.android.support:recyclerview-v7:26.+'

One way is to use the multiple class selector (no space as that is the descendant selector):

.reMode_hover:not(.reMode_selected):hover _x000D_
{_x000D_
   background-color: #f0ac00;_x000D_
}

<a href="" title="Design" class="reMode_design  reMode_hover">_x000D_
    <span>Design</span>_x000D_
</a>_x000D_
_x000D_
<a href="" title="Design" _x000D_
 class="reMode_design  reMode_hover reMode_selected">_x000D_
    <span>Design</span>_x000D_
</a>

Look at node-ffi.

node-ffi is a Node.js addon for loading and calling dynamic libraries using pure JavaScript. It can be used to create bindings to native libraries without writing any C++ code.

I think you can use JSON.stringify:

// after your each loop
JSON.stringify(values);

Try this below code for binding html through attr

.directive('dynamic', function ($compile) {
    return {
      restrict: 'A',
      replace: true,
      scope: { dynamic: '=dynamic'},
      link: function postLink(scope, element, attrs) {
        scope.$watch( 'attrs.dynamic' , function(html){
          element.html(scope.dynamic);
          $compile(element.contents())(scope);
        });
      }
    };
  });

Try this element.html(scope.dynamic); than element.html(attr.dynamic);

<p> tags have built in padding and margin. You could create a CSS selector combined with some javascript for instances when your <p> is empty. Probably overkill, but it should do what you need it to do.

CSS example: .NoPaddingOrMargin {padding: 0px; margin:0px}

Another option which doesn't require numpy is:

precision = 2  
myRoundedList = [int(elem*(10**precision)+delta)/(10.0**precision) for elem in myList]

# delta=0 for floor
# delta = 0.5 for round
# delta = 1 for ceil

Although some of them are correct, I've found quite confusing the previous responses. At the same time, the OP asked for a solution without setting a custom header or using beforeSend, so I've being looking for a clearer explanation. I hope my conclusions provide some light to others.

The code

jQuery.ajax({
    .... 
    accepts: "application/json; charset=utf-8",
    ....
});

doesn't work because accepts must be a PlainObject (not a String) according to the jQuery doc (http://api.jquery.com/jquery.ajax/). Specifically, jQuery expect zero or more key-value pairs relating each dataType with the accepted MIME type for them. So what I've finally using is:

jQuery.ajax({
    ....
    dataType: 'json',
    accepts: {
        json: 'application/json'
    },
    ....
});

Sounds like you got your answer. Passing by value is expensive, but gives you a copy to work with if you need it.

Try this:

mBox = new TextView(context);
mBox.setText(Html.fromHtml("<b>" + title + "</b>" +  "<br />" + 
      "<small>" + description + "</small>" + "<br />" + 
      "<small>" + DateAdded + "</small>"));

What's even easier is to just use the BackgroundWorker control...

Answer seems to be a little old, What I did was to use this mapper to convert a MAP

      ObjectMapper mapper = new ObjectMapper().configure(SerializationConfig.Feature.WRITE_NULL_MAP_VALUES, false);

a simple Map:

          Map<String, Object> user = new HashMap<String,Object>();
            user.put( "id",  teklif.getAccount().getId() );
            user.put( "fname", teklif.getAccount().getFname());
            user.put( "lname", teklif.getAccount().getLname());
            user.put( "email", teklif.getAccount().getEmail());
            user.put( "test", null);

Use it like this for example:

      String json = mapper.writeValueAsString(user);

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

for(var call of myObj) {
    console.log(call)
    
    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {
        result = false
        break
    }
}

Use @Test annotation on one of the test methods or annotate your test class with @RunWith(JMockit.class) if using jmock. Intellij should identify that as test class & enable navigation. Also make sure junit plugin is enabled.

I got the same same error.

I was using gmail account and Google's SMTP server to send emails. The problem was due to SMTP server refusing to authorize as it considered my web host (through whom I sent email) as an intruder.

I followed Google's process to identify my web host as an valid entity to send email through my account and problem was solved.

2018 Update

Font Awesome 5 now features light, regular and solid variants. The icon featured in this question has the following style under the different variants:

A modern answer to this question would be that different variants of the icon can be used to make the icon appear bolder or lighter. The only downside is that if you're already using solid you will have to fall back to the original answers here to make those bolder, and likewise if you're using light you'd have to do the same to make those lighter.

Font Awesome's How To Use documentation walks through how to use these variants.

Original Answer

Font Awesome makes use of the Private Use region of Unicode. For example, this .icon-remove you're using is added in using the ::before pseudo-selector, setting its content to \f00d ():

.icon-remove:before {
    content: "\f00d";
}

Font Awesome does only come with one font-weight variant, however browsers will render this as they would render any font with only one variant. If you look closely, the normal font-weight isn't as bold as the bold font-weight. Unfortunately a normal font weight isn't what you're after.

What you can do however is change its colour to something less dark and reduce its font size to make it stand out a bit less. From your image, the "tags" text appears much lighter than the icon, so I'd suggest using something like:

.tag .icon-remove {
    color:#888;
    font-size:14px;
}

Here's a JSFiddle example, and here is further proof that this is definitely a font.

you can use linkbutton for navigating to another section in the same page by using PostBackUrl="#Section2"

For MS compilers:

#define inc_enum(i) ((decltype(i)) ((int)i + 1))

enum enumtype { one, two, three, count};
for(enumtype i = one; i < count; i = inc_enum(i))
{ 
    dostuff(i); 
}

Note: this is a lot less code than the simple templatized custom iterator answer.

You can get this to work with GCC by using typeof instead of decltype, but I don't have that compiler handy at the moment to make sure it compiles.

Use a vertical bar (|) for "or".

case "$C" in
"1")
    do_this()
    ;;
"2" | "3")
    do_what_you_are_supposed_to_do()
    ;;
*)
    do_nothing()
    ;;

A lock is used for either visibility or for protecting some data from concurrent modification which may lead to race.

When you need to just make primitive type operations to be atomic there are available options like AtomicInteger and the likes.

But suppose you have two integers which are related to each other like x and y co-ordinates, which are related to each other and should be changed in an atomic manner. Then you would protect them using a same lock.

A lock should only protect the state that is related to each other. No less and no more. If you use synchronized(this) in each method then even if the state of the class is unrelated all the threads will face contention even if updating unrelated state.

class Point{
   private int x;
   private int y;

   public Point(int x, int y){
       this.x = x;
       this.y = y;
   }

   //mutating methods should be guarded by same lock
   public synchronized void changeCoordinates(int x, int y){
       this.x = x;
       this.y = y;
   }
}

In the above example I have only one method which mutates both x and y and not two different methods as x and y are related and if I had given two different methods for mutating x and y separately then it would not have been thread safe.

This example is just to demonstrate and not necessarily the way it should be implemented. The best way to do it would be to make it IMMUTABLE.

Now in opposition to Point example, there is an example of TwoCounters already provided by @Andreas where the state which is being protected by two different locks as the state is unrelated to each other.

The process of using different locks to protect unrelated states is called Lock Striping or Lock Splitting

Following code will work for all the versions. I did checked this in a device with gingerbread as well as on JellyBean device

 private void actionBarIdForAll()
    {
        int titleId = 0;

        if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.HONEYCOMB)
        {
            titleId = getResources().getIdentifier("action_bar_title", "id", "android");
        }
        else
        {
          // This is the id is from your app's generated R class when ActionBarActivity is used for SupportActionBar

            titleId = R.id.action_bar_title;
        }

        if(titleId>0)
        {
            // Do whatever you want ? It will work for all the versions.

            // 1. Customize your fonts
            // 2. Infact, customize your whole title TextView

            TextView titleView = (TextView)findViewById(titleId);
            titleView.setText("RedoApp");
            titleView.setTextColor(Color.CYAN);
        }
    }

This question already mentions, and links to other Stack Overflow questions regarding this topic.

string = string.split("\\");

In JavaScript, the backslash is used to escape special characters, such as newlines (\n). If you want to use a literal backslash, a double backslash has to be used.

So, if you want to match two backslashes, four backslashes has to be used. For example,alert("\\\\") will show a dialog containing two backslashes.

declare @sql1 nvarchar(max) 
SELECT @sql1 =
  STUFF(
         (
           select ' drop table dbo.[' + name + ']'

           FROM sys.sysobjects AS sobjects
           WHERE (xtype = 'U') AND (name LIKE 'GROUP_BASE_NEW_WORK_%')
           for xml path('')
        ),
     1, 1, '')

  execute sp_executesql @sql1

Remove the visible="false" attribute and add a CSS class that is not visible by default. Then you should be able to reference the dropdown by the correct id, for example:

$("#ctl00_cphTest_test1").show();

Above ID you should serach for in the source of the rendered page in your browser.

using angularjs:

$timeout(function(){
if(yourvariable===-1){
doSomeThingAfter5Seconds();
}
},5000)

Using Java 6 or later, the classpath option supports wildcards. Note the following:

• Use straight quotes (")
• Use *, not *.jar

Windows

java -cp "Test.jar;lib/*" my.package.MainClass

Unix

java -cp "Test.jar:lib/*" my.package.MainClass

This is similar to Windows, but uses : instead of ;. If you cannot use wildcards, bash allows the following syntax (where lib is the directory containing all the Java archive files):

java -cp "$(printf %s: lib/*.jar)"

(Note that using a classpath is incompatible with the -jar option. See also: Execute jar file with multiple classpath libraries from command prompt)

Understanding Wildcards

From the Classpath document:

Class path entries can contain the basename wildcard character *, which is considered equivalent to specifying a list of all the files in the directory with the extension .jar or .JAR. For example, the class path entry foo/* specifies all JAR files in the directory named foo. A classpath entry consisting simply of * expands to a list of all the jar files in the current directory.

A class path entry that contains * will not match class files. To match both classes and JAR files in a single directory foo, use either foo;foo/* or foo/*;foo. The order chosen determines whether the classes and resources in foo are loaded before JAR files in foo, or vice versa.

Subdirectories are not searched recursively. For example, foo/* looks for JAR files only in foo, not in foo/bar, foo/baz, etc.

The order in which the JAR files in a directory are enumerated in the expanded class path is not specified and may vary from platform to platform and even from moment to moment on the same machine. A well-constructed application should not depend upon any particular order. If a specific order is required then the JAR files can be enumerated explicitly in the class path.

Expansion of wildcards is done early, prior to the invocation of a program's main method, rather than late, during the class-loading process itself. Each element of the input class path containing a wildcard is replaced by the (possibly empty) sequence of elements generated by enumerating the JAR files in the named directory. For example, if the directory foo contains a.jar, b.jar, and c.jar, then the class path foo/* is expanded into foo/a.jar;foo/b.jar;foo/c.jar, and that string would be the value of the system property java.class.path.

The CLASSPATH environment variable is not treated any differently from the -classpath (or -cp) command-line option. That is, wildcards are honored in all these cases. However, class path wildcards are not honored in the Class-Path jar-manifest header.

Note: due to a known bug in java 8, the windows examples must use a backslash preceding entries with a trailing asterisk: https://bugs.openjdk.java.net/browse/JDK-8131329

Check PHP's strtotime-function to convert your set date/time to a timestamp: http://php.net/manual/en/function.strtotime.php

If strtotime can't handle your date/time format correctly ("4:00PM" will probably work but not "at 4PM"), you'll need to use string-functions, e.g. substr to parse/correct your format and retrieve your timestamp through another function, e.g. mktime.

Then compare the resulting timestamp with the current date/time (if ($calulated_timestamp > time()) { /* date in the future */ }) to see whether the set date/time is in the past or the future.

I suggest to read the PHP-doc on date/time-functions and get back here with some of your source-code once you get stuck.

127.0.0.1 is normally the IP address assigned to the "loopback" or local-only interface. This is a "fake" network adapter that can only communicate within the same host. It's often used when you want a network-capable application to only serve clients on the same host. A process that is listening on 127.0.0.1 for connections will only receive local connections on that socket.

"localhost" is normally the hostname for the 127.0.0.1 IP address. It's usually set in /etc/hosts (or the Windows equivalent named "hosts" somewhere under %WINDIR%). You can use it just like any other hostname - try "ping localhost" to see how it resolves to 127.0.0.1.

0.0.0.0 has a couple of different meanings, but in this context, when a server is told to listen on 0.0.0.0 that means "listen on every available network interface". The loopback adapter with IP address 127.0.0.1 from the perspective of the server process looks just like any other network adapter on the machine, so a server told to listen on 0.0.0.0 will accept connections on that interface too.

That hopefully answers the IP side of your question. I'm not familiar with Jekyll or Vagrant, but I'm guessing that your port forwarding 8080 => 4000 is somehow bound to a particular network adapter, so it isn't in the path when you connect locally to 127.0.0.1

The following as a batch file will open an elevated command prompt with the path set to the same directory as the one from where the batch file was invoked

set OLDDIR=%CD%
powershell -Command "Start-Process cmd -ArgumentList '/K cd %OLDDIR%' -Verb RunAs "

print "Number of lines: $nids\n";
print "Content: $ids\n";

How did Perl complain? print $ids should work, though you probably want a newline at the end, either explicitly with print as above or implicitly by using say or -l/$\.

If you want to interpolate a variable in a string and have something immediately after it that would looks like part of the variable but isn't, enclose the variable name in {}:

print "foo${ids}bar";

MP3 files have headers you need to respect.

You could ether use a library like Open Source Audio Library Project and write a tool around it. Or you can use a tool that understands mp3 files like Audacity.

Step 1: check your current configuration

cat .git/config

You will get:

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
    ignorecase = true
    precomposeunicode = true
[remote "origin"]
    url = https://github.com/path_to_your_git.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[user]
    name = your_username
    email = your_email
[branch "master-staging"]
    remote = origin
    merge = refs/heads/master-staging

Step 2: remove your remote origin

git remote rm origin

Step 3: add remote origin back with your username and password

git remote add origin https://your_git_username:[email protected]/path_to_your_git.git

For fix the "Overriding method... has incompatible type..." error I've changed the function declaration to

override func tableView(tableView: (UITableView!), 
                        cellForRowAtIndexPath indexPath: (NSIndexPath!)) 
    -> UITableViewCell {...}

(was -> UITableViewCell! -- with exclamation mark at the end)

I agree with Robert Martin's quote in Clean Code (as cited above): the fewer parameters the better. More than 5-7 parameters and method calls become pretty hard to comprehend. Things get especially bad if some of the parameters are optional (and so take null values), or if all the parameters have the same type (making it even harder to figure out which parameter is which). If you can bundle parameters into cohesive domain objects like Customer and Account, your code will be much more pleasant to work with.

There is an edge case: if you have a method call that takes a variable number of parameters which form a logical set, there's less cognitive overhead having more parameters. For example you may need a method that specifies a number of HTTP request retries, in terms of the number of milliseconds between retries. Three retries at 1s, 2s, and 3s intervals could be specified as:

retries(1000, 2000, 3000)

In this limited case, adding more parameters to a call doesn't increase the mental overload that much.

Another consideration is if your language supports named parameter lists and allows you to leave out optional parameters. Larger named parameter lists are easier to comprehend than larger unnamed parameter lists.

But I'd still err on the side of fewer rather than more parameters.

QTip has bug with jQuery 1.4.2. I had to switch to jQuery Bubble Pop up http://www.vegabit.com/jquery_bubble_popup_v2/#examples and it works great!

Eclipse doesn't pull the tooltips from the javadoc location. It only uses the javadoc location to prepend to the link if you say open in browser, you need to download and attach the source for the JDK in order to get the tooltips. For all the JARs under the JRE you should have the following for the javadoc location: http://java.sun.com/javase/6/docs/api/. For resources.jar, rt.jar, jsse.jar, jce.jar and charsets.jar you should attach the source available here.

Well, since this is such a hot topic... here is what works for me. I got errors if I didn't do it this way because Activate() will error out on you if you cannot see the window.

Xaml:

<Window .... 
        Topmost="True" 
        .... 
        ContentRendered="mainWindow_ContentRendered"> .... </Window>

Codebehind:

private void mainWindow_ContentRendered(object sender, EventArgs e)
{
    this.Topmost = false;
    this.Activate();
    _UsernameTextBox.Focus();
}

This was the only way for me to get the window to show on top. Then activate it so you can type in the box without having to set focus with the mouse. control.Focus() wont work unless the window is Active();

Just update the date format as like bellow

yyyy-MM-dd hh:MM:ss

It solves the problem for me and it works fine

FYI - I have been struggling with this issue for the past 3 hours. tried everything, flushing DNS, using a proxy, resetting catalog using netsh and clearing the routes. nothing worked so i decided to give windows restore a try, I did it using a windows cd -> repair -> system restore and it worked ! couldnt find any solutions online so i figured id post it

If you are using Fish shell, you can leverage the string functions:

git branch -d (git branch -l "<your pattern>" | string trim)

This is not much different from the Powershell options in some of the other answers.

Though this does not directly answer the question, but I think it is a good alternative to avoid the question altogether.

To avoid all the autoload_paths or eager_load_paths hassle, create a "lib" or a "misc" directory under "app" directory. Place codes as you would normally do in there, and Rails will load files just like how it will load (and reload) model files.

Custom Error Decorator

This is based on George Bailey's answer, but extends and simplifies the original idea. It is written in CoffeeScript, but is easy to convert to JavaScript. The idea is extend Bailey's custom error with a decorator that wraps it, allowing you to create new custom errors easily.

Note: This will only work in V8. There is no support for Error.captureStackTrace in other environments.

Define

The decorator takes a name for the error type, and returns a function that takes an error message, and encloses the error name.

CoreError = (@message) ->

    @constructor.prototype.__proto__ = Error.prototype
    Error.captureStackTrace @, @constructor
    @name = @constructor.name

BaseError = (type) ->

    (message) -> new CoreError "#{ type }Error: #{ message }"

Use

Now it is simple to create new error types.

StorageError   = BaseError "Storage"
SignatureError = BaseError "Signature"

For fun, you could now define a function that throws a SignatureError if it is called with too many args.

f = -> throw SignatureError "too many args" if arguments.length

This has been tested pretty well and seems to work perfectly on V8, maintaing the traceback, position etc.

Note: Using new is optional when constructing a custom error.

Setting .value to the value of one of the options works on all vaguely-current browsers. On very old browsers, you used to have to set the selectedIndex:

document.getElementById("select").selectedIndex = 0;

If neither that nor your original code is working, I wonder if you might be using IE and have something else on the page creating something called "select"? (Either as a name or as a global variable?) Because some versions of IE have a problem where they conflate namespaces. Try changing the select's id to "fluglehorn" and if that works, you know that's the problem.

No, you're not allocating memory for y->x twice.

Instead, you're allocating memory for the structure (which includes a pointer) plus something for that pointer to point to.

Think of it this way:

         1          2
        +-----+    +------+
y------>|  x------>|  *x  |
        |  n  |    +------+
        +-----+

So you actually need the two allocations (1 and 2) to store everything.

Additionally, your type should be struct Vector *y since it's a pointer, and you should never cast the return value from malloc in C since it can hide certain problems you don't want hidden - C is perfectly capable of implicitly converting the void* return value to any other pointer.

And, of course, you probably want to encapsulate the creation of these vectors to make management of them easier, such as with:

struct Vector {
    double *data;    // no place for x and n in readable code :-)
    size_t size;
};

struct Vector *newVector (size_t sz) {
    // Try to allocate vector structure.

    struct Vector *retVal = malloc (sizeof (struct Vector));
    if (retVal == NULL)
        return NULL;

    // Try to allocate vector data, free structure if fail.

    retVal->data = malloc (sz * sizeof (double));
    if (retVal->data == NULL) {
        free (retVal);
        return NULL;
    }

    // Set size and return.

    retVal->size = sz;
    return retVal;
}

void delVector (struct Vector *vector) {
    // Can safely assume vector is NULL or fully built.

    if (vector != NULL) {
        free (vector->data);
        free (vector);
    }
}

By encapsulating the creation like that, you ensure that vectors are either fully built or not built at all - there's no chance of them being half-built. It also allows you to totally change the underlying data structures in future without affecting clients (for example, if you wanted to make them sparse arrays to trade off space for speed).

You don't have g++ installed, simple way to have all the needed build tools is to install the package build-essential:

sudo apt-get install build-essential

, or just the g++ package:

sudo apt-get install g++

I ran across this question, and the one line of code I needed was hiding in big blocks of code.

Short answer: this.files[0].size

By the way, no JQuery needed.

I use the following object:

function Padder(len, pad) {
  if (len === undefined) {
    len = 1;
  } else if (pad === undefined) {
    pad = '0';
  }

  var pads = '';
  while (pads.length < len) {
    pads += pad;
  }

  this.pad = function (what) {
    var s = what.toString();
    return pads.substring(0, pads.length - s.length) + s;
  };
}

With it you can easily define different "paddings":

var zero4 = new Padder(4);
zero4.pad(12); // "0012"
zero4.pad(12345); // "12345"
zero4.pad("xx"); // "00xx"
var x3 = new Padder(3, "x");
x3.pad(12); // "x12"

This worked for me like a magic.

I logged into database and registered the listener.

An instance variable is a variable that is a member of an instance of a class (i.e., associated with something created with a new), whereas a class variable is a member of the class itself.

Every instance of a class will have its own copy of an instance variable, whereas there is only one of each static (or class) variable, associated with the class itself.

What’s the difference between a class variable and an instance variable?

This test class illustrates the difference:

public class Test {
   
    public static String classVariable = "I am associated with the class";
    public String instanceVariable = "I am associated with the instance";
    
    public void setText(String string){
        this.instanceVariable = string;
    }
    
    public static void setClassText(String string){
        classVariable = string;
    }
    
    public static void main(String[] args) {
        Test test1 = new Test();
        Test test2 = new Test();
        
        // Change test1's instance variable
        test1.setText("Changed");
        System.out.println(test1.instanceVariable); // Prints "Changed"
        // test2 is unaffected
        System.out.println(test2.instanceVariable); // Prints "I am associated with the instance"
        
        // Change class variable (associated with the class itself)
        Test.setClassText("Changed class text");
        System.out.println(Test.classVariable); // Prints "Changed class text"
        
        // Can access static fields through an instance, but there still is only one
        // (not best practice to access static variables through instance)
        System.out.println(test1.classVariable); // Prints "Changed class text"
        System.out.println(test2.classVariable); // Prints "Changed class text"
    }
}

That's as easy as

IsNull(FieldName, 0)

Or more completely:

SELECT iar.Description, 
  ISNULL(iai.Quantity,0) as Quantity, 
  ISNULL(iai.Quantity * rpl.RegularPrice,0) as 'Retail', 
  iar.Compliance 
FROM InventoryAdjustmentReason iar
LEFT OUTER JOIN InventoryAdjustmentItem iai  on (iar.Id = iai.InventoryAdjustmentReasonId)
LEFT OUTER JOIN Item i on (i.Id = iai.ItemId)
LEFT OUTER JOIN ReportPriceLookup rpl on (rpl.SkuNumber = i.SkuNo)
WHERE iar.StoreUse = 'yes'

I think that you should make the reference to your config file

26399:C 16 Jan 08:51:13.413 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

you can try to start your redis server like

./redis-server /path/to/redis-stable/redis.conf

The easiest way for me to convert a date was to stringify it then slice it.

var event = new Date("Fri Apr 05 2019 16:59:00 GMT-0700 (Pacific Daylight Time)");

let date = JSON.stringify(event)
date = date.slice(1,11)

// console.log(date) = '2019-04-05'

A common use case I have is a dictionary of numpy arrays or lists where I know they're all the same length, and I just need to know one of them (e.g. I'm plotting timeseries data and each timeseries has the same number of timesteps). I often use this:

length = len(next(iter(d.values())))

You can define your own exception class extending java.lang.Exception (that's for a checked exception - these which must be caught), or extending java.lang.RuntimeException - these exceptions does not have to be caught.

The other solution is to review the Java API and finding an appropriate exception describing your situation: in this particular case I think that the best one would be IllegalArgumentException.

This is impossible to answer and has been brought up many many times before. Do a search, read those threads, then pick the framework you and your team have experience with.

I've gotten around this with

mystr = ' '.join(
        ["Why, hello there",
         "wonderful stackoverflow people!"])

in the past. It's not perfect, but it works nicely for very long strings that need to not have line breaks in them.

Use the jQuery hashchange event plugin instead. Regarding your full ajax navigation, try to have SEO friendly ajax. Otherwise your pages shown nothing in browsers with JavaScript limitations.

In contrast to what the accepted answer proposes, the documentation says that for JSONArray() you must use put(value) no add(value).

I've heard this called "auto versioning". The most common method is to include the static file's modification time somewhere in the URL, and strip it out using rewrite handlers or URL configurations:

I'm afraid that you've put constraints on the set of solutions that, well, leave you with the null set.

Using :set textwidth=80 will fix all of the problems you mentioned except that you can't easily see the line limit coming up. If you :set ruler, you'll enable the x,y position display on the status bar, which you can use to see which column you're in.

Aside from that, I'm not sure what to tell you. It's a shame to lose the number column, fold column and splits just because you have to :set columns=80.

When you push a new branch the first time use: >git push -u origin

After that, you can just type a shorter command: >git push

The first-time -u option created a persistent upstream tracking branch with your local branch.

Thanks to @LyphTEC that gave a very interesting way to open an Office file in edit mode!

It gave me the idea to change the function _DispEx that is called when the user clicks on a file into a document library. By hacking the original function we can them be able to open a dialog (for Firefox/Chrome) and ask the user if he/she wants to readonly or edit the file:

See below the JavaScript code I used. My code is for Excel files, but it could be modified to work with Word documents too:

    /**

 * @param  {HTMLElement} p the <A> element
 * @param  {HTMLEvent} a the click event
 * @param  {Boolean} h TRUE
 * @param  {Boolean} e FALSE
 * @param  {Boolean} g FALSE
 * @param  {Strin} k the ActiveX command (e.g. "SharePoint.OpenDocuments.3")
 * @param  {Number} c 0
 * @param  {String} o the activeX command, here we look at "SharePoint.OpenDocuments"
 * @param  {String} m
 * @param  {String} b the replacement URL to the xslviewer

Create a Shell script that checks if tomcat is up or down and set a cron for sh to make it check every few minutes, and auto start tomcat if down. Sample Snippet of code below

TOMCAT_PID=$(ps -ef | awk '/[t]omcat/{print $2}')
echo TOMCAT PROCESSID $TOMCAT_PID

if [ -z "$TOMCAT_PID" ]
then
    echo "TOMCAT NOT RUNNING"
    sudo /opt/tomcat/bin/startup.sh
else
   echo "TOMCAT RUNNING"
fi

I think it'd be okay if you commented it, e.g. // ^ == XOR.

There are few steps to overcome this problem:

1. Uninstall Java related softwares
2. Uninstall NodeJS if installed
3. Download java 8 update161
4. Install it

The problem solved: The problem raised to me at the uninstallation on openfire server.

MYSQL_HOME variable value:C:\Program Files\MySQL\MySQL Server 5.0\bin %MYSQL_HOME%\bin

See the problem? This resolves to a path of C:\Program Files\MySQL\MySQL Server 5.0\bin\bin

Try the below:

testlist = [1,2,3,5,3,1,2,1,6]    
position=0
for i in testlist:
   if i == 1:
      print(position)
   position=position+1

in order for this to work:

yourButton.isEnabled = false

you need to create an outlet in addition to your UI button.

In a ListView set:

android:choiceMode="singleChoice"

Create a selector for a background (drawable/selector_gray.xml):

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/gray" android:state_checked="true" />
    <item android:drawable="@color/white" />
</selector>

Add an item for a list:

<?xml version="1.0" encoding="utf-8"?>
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:padding="5dp"
    android:background="@drawable/selector_gray"
    android:textColor="@color/colorPrimary"
    tools:text="Your text" />

In a ViewHolder you can inflate this item.

It is better to use ng-switch

<div ng-switch on="details.Payment[0].Status">
    <div ng-switch-when="1">
        <!-- code to render a large video block-->
    </div>
    <div ng-switch-default>
        <!-- code to render the regular video block -->
    </div>
</div>

You can like:

window.open('url', 'window name', 'window settings')

jQuery:

$('a#link_id').click(function(){
  window.open('url', 'window name', 'window settings');
  return false;
});

You could also set the target to _blank actually.

How to install PyQt4 on anaconda python 2 on Windows:

At first I have tried to isntall pyqt4 via pip install:

C:\Users\myuser\Anaconda2\Scripts\pip.exe search pyqt4 > pyqt4.txt

It shows:

PyQt4 (4.11.4) - Python bindings for the Qt cross platform GUI toolkit

But when I tried to install, it gives an error:

C:\Users\myuser\Anaconda2\Scripts\pip.exe install PyQt4

Second: create a converter to mapping the model extending the AbstractHttpMessageConverter

Third: tell to spring use this converter implementing a WebMvcConfigurer.class overriding the configureMessageConverters method

Fourth and final: using this implementation setting in the mapping inside your controller the consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE and @RequestBody in front of your object.

I'm using spring boot 2.

You are consuming a line at, which is discarded

while((str=input.readLine())!=null && str.length()!=0)

and reading a bigint at

BigInteger n = new BigInteger(input.readLine());

so try getting the bigint from string which is read as

BigInteger n = new BigInteger(str);

   Constructor used: BigInteger(String val)

Aslo change while((str=input.readLine())!=null && str.length()!=0) to

while((str=input.readLine())!=null)

see related post string to bigint

readLine()
Returns:
    A String containing the contents of the line, not including any line-termination characters, or null if the end of the stream has been reached

Very often you have no option to setup the sending server so what I did I changed the XMLHttpRequest.open call in my javascript to a local get-file.php file where I have the following code in it:

<?php_x000D_
  $file = file($_GET['url']);_x000D_
  echo implode('', $file);_x000D_
?>

javascript is doing this:

var xhttp = new XMLHttpRequest();_x000D_
xhttp.onreadystatechange = function() {_x000D_
  if (this.readyState == 4 && this.status == 200) {_x000D_
    // File content is now in the this.responseText_x000D_
  }_x000D_
};_x000D_
xhttp.open("GET", "get-file.php?url=http://site/file", true);_x000D_
xhttp.send();

In my case this solved the restriction/situation just perfectly. No need to hack Firefox or servers. Just load your javascript/html file with that small php file into the server and you're done.

type is actually a metaclass -- a class that creates another classes. Most metaclass are the subclasses of type. The metaclass receives the new class as its first argument and provide access to class object with details as mentioned below:

>>> class MetaClass(type):
...     def __init__(cls, name, bases, attrs):
...         print ('class name: %s' %name )
...         print ('Defining class %s' %cls)
...         print('Bases %s: ' %bases)
...         print('Attributes')
...         for (name, value) in attrs.items():
...             print ('%s :%r' %(name, value))
... 

>>> class NewClass(object, metaclass=MetaClass):
...    get_choch='dairy'
... 
class name: NewClass
Bases <class 'object'>: 
Defining class <class 'NewClass'>
get_choch :'dairy'
__module__ :'builtins'
__qualname__ :'NewClass'

Note:

Notice that the class was not instantiated at any time; the simple act of creating the class triggered execution of the metaclass.

Inspired by yarkee, I combined it with some of the code I already got. You can also call this from another script, just by calling the function run_unit_tests() without requiring to use the command line, or just call it from the command line with python3 my_test_file.py.

import my_test_file
my_test_file.run_unit_tests()

Sadly this only works for Python 3.3 or above:

import unittest

class LineBalancingUnitTests(unittest.TestCase):

    @classmethod
    def setUp(self):
        self.maxDiff = None

    def test_it_is_sunny(self):
        self.assertTrue("a" == "a")

    def test_it_is_hot(self):
        self.assertTrue("a" != "b")

Runner code:

#! /usr/bin/env python3
# -*- coding: utf-8 -*-
import unittest
from .somewhere import LineBalancingUnitTests

def create_suite(classes, unit_tests_to_run):
    suite = unittest.TestSuite()
    unit_tests_to_run_count = len( unit_tests_to_run )

    for _class in classes:
        _object = _class()
        for function_name in dir( _object ):
            if function_name.lower().startswith( "test" ):
                if unit_tests_to_run_count > 0 \
                        and function_name not in unit_tests_to_run:
                    continue
                suite.addTest( _class( function_name ) )
    return suite

def run_unit_tests():
    runner = unittest.TextTestRunner()
    classes =  [
        LineBalancingUnitTests,
    ]

    # Comment all the tests names on this list, to run all Unit Tests
    unit_tests_to_run =  [
        "test_it_is_sunny",
        # "test_it_is_hot",
    ]
    runner.run( create_suite( classes, unit_tests_to_run ) )

if __name__ == "__main__":
    print( "\n\n" )
    run_unit_tests()

Editing the code a little, you can pass an array with all unit tests you would like to call:

...
def run_unit_tests(unit_tests_to_run):
    runner = unittest.TextTestRunner()

    classes = \
    [
        LineBalancingUnitTests,
    ]

    runner.run( suite( classes, unit_tests_to_run ) )
...

And another file:

import my_test_file

# Comment all the tests names on this list, to run all unit tests
unit_tests_to_run = \
[
    "test_it_is_sunny",
    # "test_it_is_hot",
]

my_test_file.run_unit_tests( unit_tests_to_run )

Alternatively, you can use load_tests Protocol and define the following method in your test module/file:

def load_tests(loader, standard_tests, pattern):
    suite = unittest.TestSuite()

    # To add a single test from this file
    suite.addTest( LineBalancingUnitTests( 'test_it_is_sunny' ) )

    # To add a single test class from this file
    suite.addTests( unittest.TestLoader().loadTestsFromTestCase( LineBalancingUnitTests ) )

    return suite

If you want to limit the execution to one single test file, you just need to set the test discovery pattern to the only file where you defined the load_tests() function.

#! /usr/bin/env python3
# -*- coding: utf-8 -*-
import os
import sys
import unittest

test_pattern = 'mytest/module/name.py'
PACKAGE_ROOT_DIRECTORY = os.path.dirname( os.path.realpath( __file__ ) )

loader = unittest.TestLoader()
start_dir = os.path.join( PACKAGE_ROOT_DIRECTORY, 'testing' )

suite = loader.discover( start_dir, test_pattern )
runner = unittest.TextTestRunner( verbosity=2 )
results = runner.run( suite )

print( "results: %s" % results )
print( "results.wasSuccessful: %s" % results.wasSuccessful() )

sys.exit( not results.wasSuccessful() )

2. Is there a way to loop through and execute all of the functions in a Python class?
3. looping over all member variables of a class in python

Alternatively, to the last main program example, I came up with the following variation after reading the unittest.main() method implementation:

1. https://github.com/python/cpython/blob/master/Lib/unittest/main.py#L65

#! /usr/bin/env python3
# -*- coding: utf-8 -*-

import os
import sys
import unittest

PACKAGE_ROOT_DIRECTORY = os.path.dirname( os.path.realpath( __file__ ) )
start_dir = os.path.join( PACKAGE_ROOT_DIRECTORY, 'testing' )

from testing_package import main_unit_tests_module
testNames = ["TestCaseClassName.test_nameHelloWorld"]

loader = unittest.TestLoader()
suite = loader.loadTestsFromNames( testNames, main_unit_tests_module )

runner = unittest.TextTestRunner(verbosity=2)
results = runner.run( suite )

print( "results: %s" % results )
print( "results.wasSuccessful: %s" % results.wasSuccessful() )
sys.exit( not results.wasSuccessful() )

I found the it wonderful to cover multiple variants of date time format like this:

final DateTimeFormatterBuilder dtfb = new DateTimeFormatterBuilder();
dtfb.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSS"))
    .appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"))
    .appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SS"))
    .appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.S"))
    .parseDefaulting(ChronoField.HOUR_OF_DAY, 0)
    .parseDefaulting(ChronoField.MINUTE_OF_HOUR, 0)
    .parseDefaulting(ChronoField.SECOND_OF_MINUTE, 0);

request has been deprecated as of February 2020, I'll leave the answer below for historical reasons, but please consider moving to an alternative listed in this issue.

I did something similar but I used request instead:

var request = require('request');
app.get('/', function(req,res) {
  //modify the url in any way you want
  var newurl = 'http://google.com/';
  request(newurl).pipe(res);
});

I hope this helps, took me a while to realize that I could do this :)

This also works in matplotlib 3:

x1 = [0,1,2,3]
squad = ['Fultz','Embiid','Dario','Simmons']

plt.xticks(x1, squad, rotation=45)

The /Date(ms + timezone)/ is a ASP.NET syntax for JSON dates. You might want to use a library like momentjs for parsing such dates. It would come in handy if you need to manipulate or print the dates any time later.

From this document, this DTU percent is determined by this query:

SELECT end_time,   
  (SELECT Max(v)    
   FROM (VALUES (avg_cpu_percent), (avg_data_io_percent), 
(avg_log_write_percent)) AS    
   value(v)) AS [avg_DTU_percent]   
FROM sys.dm_db_resource_stats;  

looks like the max of avg_cpu_percent, avg_data_io_percent and avg_log_write_percent

So does C99.

The IEEE 754 floating point representation used by all modern processors has several special bit patterns reserved for positive infinity (sign=0, exp=~0, frac=0), negative infinity (sign=1, exp=~0, frac=0), and many NaN (Not a Number: exp=~0, frac?0).

All you need to worry about: some arithmetic may cause floating point exceptions/traps, but those aren't limited to only these "interesting" constants.

How about create a bat file, run the batch file before closing, and then close the current instance.

The batch file does this:

1. wait in a loop to check whether the process has exited.
2. start the process.

add the section in your code example

"linterOptions": {
"exclude": [
  "node_modules/**/*.",
  "db/**/*.",
  "integrations/**/*."
]

},

Below code for an uploading a single file at a time. This is correct and perfect to upload a single file. Read all commented instructions and follow the code. Definitely, it is worked.

public function upload_file() {
    ***// Upload folder location***
    $config['upload_path'] = './public/upload/';

    ***// Allowed file type***
    $config['allowed_types'] = 'jpg|jpeg|png|pdf';

    ***// Max size, i will set 2MB***
    $config['max_size'] = '2024';

    $config['max_width'] = '1024';
    $config['max_height'] = '768';

    ***// load upload library***            
    $this->load->library('upload', $config);

    ***// do_upload is the method, to send the particular image and file on that 
       // particular 
       // location that is detail in $config['upload_path']. 
       // In bracks will set name upload, here you need to set input name attribute 
       // value.***

    if($this->upload->do_upload('upload')) {
       $data = $this->upload->data();
       $post['upload'] = $data['file_name'];
    } else {
      $error = array('error' => $this->upload->display_errors());
    }
 }

Open up terminal first and then go to directory of web server

cd /Library/WebServer/Documents

and then type this and what you will do is you will give read and write permission

sudo chmod -R o+w /Library/WebServer/Documents

This will surely work!

I have also faced this issue when my window service started throwing the exception

System.UnauthorizedAccessException: Access to the path "C:\\Order\\Media
44aa4857-3bac-4a18-a307-820450361662.mp4" is denied.

So as a solution, I checked the user account associated with my service, as shown in below screen capture

So in my case it was NETWORK SERVICE

And then went to the folder properties to check if the associated user account also exists under their permission tab. It was missing in my case and when I added it and it fixed my issue.

MAC users - this issue was winding me up, as its not possible to open two different Visual Studio instances at the same time. Ive found a solution that works fine, though its a little unorthodox : get the latest beta testing version, which will install alongside your normal VS install in a separate sandbox (it does this automatically). You can then run both versions side by side, which is enough for what I needed - to be able to examine one project for structure, code etc., while doing the actual coding I need to do in the 'current' VS install instance.

You could use the following snippet:

private void textBox1_TextChanged(object sender, EventArgs e)
{
    if (!System.Text.RegularExpressions.Regex.IsMatch(textBox1.Text, "^[a-zA-Z ]"))
    {
        MessageBox.Show("This textbox accepts only alphabetical characters");
        textBox1.Text.Remove(textBox1.Text.Length - 1);
    }
}

I made this work in this way:

<button class="btn" ng-click='toggleClass($event)'>button one</button>
<button class="btn" ng-click='toggleClass($event)'>button two</button>

in your controller:

$scope.toggleClass = function (event) {
    $(event.target).toggleClass('active');
}

Well the answer was sitting right in front of me the whole time.

In SQL Server Management Studio 2008 there is a Debug button in the toolbar. Set a break point in a query window to step through.

I dismissed this functionality at the beginning because I didn't think of stepping INTO the stored procedure, which you can do with ease.

SSMS basically does what FinnNK mentioned with the MSDN walkthrough but automatically.

So easy! Thanks for your help FinnNK.

Edit: I should add a step in there to find the stored procedure call with parameters I used SQL Profiler on my database.

or you can call tableView method to set the footer height in 1 point, and it will add an last line, but you can hide it too, by setting footer background color.

code:

func tableView(tableView: UITableView,heightForFooterInSection section: Int) -> CGFloat {

}

looks like last line

MSI is an installer file which installs your program on the executing system.

Setup.exe is an application (executable file) which has msi file(s) as its one of the resources. Executing Setup.exe will in turn execute msi (the installer) which writes your application to the system.

Edit (as suggested in comment): Setup executable files don't necessarily have an MSI resource internally

You can use the built in dir() function to get a list of all the attributes a module has. Try this at the command line to see how it works.

>>> import moduleName
>>> dir(moduleName)

Also, you can use the hasattr(module_name, "attr_name") function to find out if a module has a specific attribute.

See the Guide to Python introspection for more information.

must please see guys that the error is in the cv2.imread() .Give the right path of the image. and firstly, see if your system loads the image or not. this can be checked first by simple load of image using cv2.imread(). after that ,see this code for the face detection

import numpy as np
import cv2

cascPath = "/Users/mayurgupta/opt/anaconda3/lib/python3.7/site-   packages/cv2/data/haarcascade_frontalface_default.xml"

eyePath = "/Users/mayurgupta/opt/anaconda3/lib/python3.7/site-packages/cv2/data/haarcascade_eye.xml"

smilePath = "/Users/mayurgupta/opt/anaconda3/lib/python3.7/site-packages/cv2/data/haarcascade_smile.xml"

face_cascade = cv2.CascadeClassifier(cascPath)
eye_cascade = cv2.CascadeClassifier(eyePath)
smile_cascade = cv2.CascadeClassifier(smilePath)

img = cv2.imread('WhatsApp Image 2020-04-04 at 8.43.18 PM.jpeg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

faces = face_cascade.detectMultiScale(gray, 1.3, 5)
for (x,y,w,h) in faces:
    img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
    roi_gray = gray[y:y+h, x:x+w]
    roi_color = img[y:y+h, x:x+w]
    eyes = eye_cascade.detectMultiScale(roi_gray)
    for (ex,ey,ew,eh) in eyes:
        cv2.rectangle(roi_color,(ex,ey),(ex+ew,ey+eh),(0,255,0),2)

cv2.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()

Here, cascPath ,eyePath ,smilePath should have the right actual path that's picked up from lib/python3.7/site-packages/cv2/data here this path should be to picked up the haarcascade files

I'd give a general rule of thumb that if you have a large codebase, all built on top of lower level libraries (eg a Utils or Gui framework), which you want to partition into more manageable libraries then make them static libraries. Dynamic libraries don't really buy you anything and there are fewer surprises -- there will only be one instance of singletons for instance.

If you have a library that is entirely separate to the rest of the codebase (eg a third party library) then consider making it a dll. If the library is LGPL you may need to use a dll anyway due to the licensing conditions.

Here's a way!

<?php

$url = "http://www.google.com";

if(@file_get_contents($url)){
echo "Url Exists!";
} else {
echo "Url Doesn't Exist!";
}

?>

This simple script simply makes a request to the URL for its source code. If the request is completed successfully, it will output "URL Exists!". If not, it will output "URL Doesn't Exist!".

Note: There is no magic to animating a gif: it is either an animated gif or it is not. If the gif is not visible, very likely the path to the gif is wrong - or, as in your case, the container (div/p/etc) is not large enough to display it. In your code sample, you did not specify height or width and that appeared to be problem.

If the gif is displayed but not animating, see reference links at very bottom of this answer.

Displaying the gif + overlay, however, is easier than you might think.

All you need are two absolute-position DIVs: an overlay div, and a div that contains your loading gif. Both have higher z-index than your page content, and the image has a higher z-index than the overlay - so they will display above the page when visible.

So, when the button is pressed, just unhide those two divs. That's it!

Once upon a midnight dreary, while I pondered weak and weary, over many a quaint and curious routine of forgotten code... While I nodded, nearly napping, suddenly there came a tapping... as of someone gently rapping - rapping at my office door. 'Tis the team leader, I muttered, tapping at my office door - only this and nothing more. Ah, distinctly I remember it was in the bleak December and each separate React print-out lay there crumpled on the floor. Eagerly I wished the morrow; vainly I had sought to borrow from Stack-O surcease from sorrow - sorrow for my routine's core. For the brilliant but unworking code my angels seem to just ignore. I'll be tweaking code... forevermore! - <a href="http://www.online-literature.com/poe/335/" target="_blank">Apologies To Poe</a></div>_x000D_

You might enjoy playing with the new backdrop-filter:blur(_px) css property that gives a blur effect to the underlying content, as used in above demo... (As of April 2020: works in Chrome, Edge, Safari, Android, but not yet in Firefox)

You can also consider using Record, like this:

const someArray: Record<string, string>[] = [
    {'first': 'one'},
    {'second': 'two'}
];

Or write something like this:

const someArray: {key: string, value: string}[] = [
    {key: 'first', value: 'one'},
    {key: 'second', value: 'two'}
];

Below command worked out pretty good:

javac -version

I also manually verified by navigating to the Java Folder on my Mac

/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk

The conventional syntax is d[key] = value, but if your keyboard is missing the square bracket keys you could also do:

d.__setitem__(key, value)

In fact, defining __getitem__ and __setitem__ methods is how you can make your own class support the square bracket syntax. See https://python.developpez.com/cours/DiveIntoPython/php/endiveintopython/object_oriented_framework/special_class_methods.php

You can convert a string to a DATE using the TO_DATE function, then reformat the date as another string using TO_CHAR, i.e.:

SELECT TO_CHAR(
         TO_DATE('15/August/2009,4:30 PM'
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM DUAL;

15-08-2009

For example, if your table name is MYTABLE and the varchar2 column is MYDATESTRING:

SELECT TO_CHAR(
         TO_DATE(MYDATESTRING
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM MYTABLE;

For static resources right caching would be to use query parameters with value of each deployment or file version. This will have effect of clearing cache after each deployment.

/Content/css/Site.css?version={FileVersionNumber}

Here is ASP.NET MVC example.

<link href="@Url.Content("~/Content/Css/Reset.css")[email protected]().Assembly.GetName().Version" rel="stylesheet" type="text/css" />

Don't forget to update assembly version.

$given = 685;

 /*
 * In case $given == 86400, gmdate( "H" ) will convert it into '00' i.e. midnight.
 * We would need to take this into consideration, and so we will first
 * check the ratio of the seconds i.e. $given:$number_of_sec_in_a_day
 * and then after multiplying it by the number of hours in a day (24), we
 * will just use "floor" to get the number of hours as the rest would
 * be the minutes and seconds anyways.
 *
 * We can also have minutes and seconds combined in one variable,
 * e.g. $min_sec = gmdate( "i:s", $given );
 * But for versatility sake, I have taken them separately.
 */

$hours = ( $given > 86399 ) ? '0'.floor( ( $given / 86400 ) * 24 )-gmdate( "H", $given ) : gmdate("H", $given );

$min = gmdate( "i", $given );

$sec = gmdate( "s", $given );

echo $formatted_string = $hours.':'.$min.':'.$sec;

To convert it into a function:

function getHoursFormat( $given ){

 $hours = ( $given > 86399 ) ? '0'.floor( ( $given / 86400 ) * 24 )-gmdate( "H", $given ) : gmdate("H", $given );

 $min = gmdate( "i", $given );

 $sec = gmdate( "s", $given );

 $formatted_string = $hours.':'.$min.':'.$sec;

 return $formatted_string;

}

Every class or interface can be used as a type in TypeScript.

 const date = new Date();

will already know about the date type definition as Date is an internal TypeScript object referenced by the DateConstructor interface.

And for the constructor you used, it is defined as:

interface DateConstructor {
    new(): Date;
    ...
}

To make it more explicit, you can use:

 const date: Date = new Date();

You might be missing the type definitions though, the Date is coming for my example from the ES6 lib, and in my tsconfig.json I have defined:

"compilerOptions": {
    "target": "ES6",
    "lib": [
        "es6",
        "dom"
    ],

You might adapt these settings to target your wanted version of JavaScript.

The Date is by the way an Interface from lib.es6.d.ts:

/** Enables basic storage and retrieval of dates and times. */
interface Date {
    /** Returns a string representation of a date. The format of the string depends on the locale. */
    toString(): string;
    /** Returns a date as a string value. */
    toDateString(): string;
    /** Returns a time as a string value. */
    toTimeString(): string;

List is an interface. You need a specific class in the end so either try

List l = new ArrayList();

or

List l = new LinkedList();

Whichever suit your needs.

Get Both View Position and Dimension on screen

val viewTreeObserver: ViewTreeObserver = videoView.viewTreeObserver;

    if (viewTreeObserver.isAlive) {
        viewTreeObserver.addOnGlobalLayoutListener(object : ViewTreeObserver.OnGlobalLayoutListener {
            override fun onGlobalLayout() {
                //Remove Listener
                videoView.viewTreeObserver.removeOnGlobalLayoutListener(this);
                
                //View Dimentions
                viewWidth = videoView.width;
                viewHeight = videoView.height;

                //View Location
                val point = IntArray(2)
                videoView.post {
                    videoView.getLocationOnScreen(point) // or getLocationInWindow(point)
                    viewPositionX = point[0]
                    viewPositionY = point[1]
                }

            }
        });
    }

Here's a compact way to do something different in all four cases:

if(empty($youtube)) {
    if(empty($link)) {
        # both empty
    } else {
        # only $youtube not empty
    }
} else {
    if(empty($link)) {
        # only $link empty
    } else {
        # both not empty
    }
}

If you want to use an expression instead, you can use ?: instead:

echo empty($youtube) ? ( empty($link) ? 'both empty' : 'only $youtube not empty' )
                     : ( empty($link) ? 'only $link empty' : 'both not empty' );

Use an interval:

select some_date_column + interval '1' hour 
from your_table;

Like this:

import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);

Or adding from an Array/ or multiple literals; wrap to a list, first.

Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b));         // from an array variable
b.addAll( Arrays.asList( 8, 9, 10));  // from literals

To get the intersection:

// copies all from A;  then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print;   r.toString() implied.
System.out.println("A intersect B="+r);

Hope this answer helps. Vote for it!

TortoiseSVN is an astonishingly good Windows client for the Subversion version control system. One feature which I just discovered that it has is that when you click to get a diff between versions of an Excel file, it will open both versions in Excel and highlight (in red) the cells that were changed. This is done through the magic of a vbs script, described here.

You may find this useful even if NOT using TortoiseSVN.

The way to do this is to set the EnableHeadersVisualStyles flag for the data grid view to False, and set the background colour via the ColumnHeadersDefaultCellStyle.BackColor property. For example, to set the background colour to blue, use the following (or set in the designer if you prefer):

_dataGridView.ColumnHeadersDefaultCellStyle.BackColor = Color.Blue;
_dataGridView.EnableHeadersVisualStyles = false;

If you do not set the EnableHeadersVisualStyles flag to False, then the changes you make to the style of the header will not take effect, as the grid will use the style from the current users default theme. The MSDN documentation for this property is here.

The way I did this is similar to the code that the accepted answer provided, bit is a bit different so I thought I would put it out there as well. Note that this sorting is being done to a DataTable before it is being bound to the GridView.DataSource.

Option One: Using ViewState

void DataGrid_Sorting(object sender, GridViewSortEventArgs e)
{
    if (e.SortExpression == (string)ViewState["SortColumn"])
    {
        // We are resorting the same column, so flip the sort direction
        e.SortDirection = 
            ((SortDirection)ViewState["SortColumnDirection"] == SortDirection.Ascending) ? 
            SortDirection.Descending : SortDirection.Ascending;
    }
    // Apply the sort
    this._data.DefaultView.Sort = e.SortExpression +
        (string)((e.SortDirection == SortDirection.Ascending) ? " ASC" : " DESC");
    ViewState["SortColumn"] = e.SortExpression;
    ViewState["SortColumnDirection"] = e.SortDirection;
}

Option Two: Using Session

Note that the following is being provided for legacy purposes in the event that you see it in the field, or that you are still supporting company systems that are targeting older browsers.

void DataGrid_Sorting(object sender, GridViewSortEventArgs e)
{
    if (e.SortExpression == (string)HttpContext.Current.Session["SortColumn"])
    {
        // We are resorting the same column, so flip the sort direction
        e.SortDirection = 
            ((SortDirection)HttpContext.Current.Session["SortColumnDirection"] == SortDirection.Ascending) ? 
            SortDirection.Descending : SortDirection.Ascending;
    }
    // Apply the sort
    this._data.DefaultView.Sort = e.SortExpression +
        (string)((e.SortDirection == SortDirection.Ascending) ? " ASC" : " DESC");
    HttpContext.Current.Session["SortColumn"] = e.SortExpression;
    HttpContext.Current.Session["SortColumnDirection"] = e.SortDirection;
}

Sure is easy with pure JS, just do this, work for fixed and animated HTML 5 panels too, i made and try this code and it works for any brower (include IE 8):

<script type="text/javascript">
    function fGetCSSProperty(s, e) {
        try { return s.currentStyle ? s.currentStyle[e] : window.getComputedStyle(s)[e]; }
        catch (x) { return null; } 
    }
    function fGetOffSetParent(s) {
        var a = s.offsetParent || document.body;

        while (a && a.tagName && a != document.body && fGetCSSProperty(a, 'position') == 'static')
            a = a.offsetParent;
        return a;
    }
    function GetPosition(s) {
        var b = fGetOffSetParent(s);

        return { Left: (b.offsetLeft + s.offsetLeft), Top: (b.offsetTop + s.offsetTop) };
    }    
</script>

Depends on the database server. MySQL doesn't care, its basically the same thing.

Oracle, DB2, and other enterprise level database solutions make a distinction. Usually a schema is a collection of tables and a Database is a collection of schemas.

None of the above worked for me using JQM 1.2.0

This did work for me:

.ui-page.ui-body-c {
    background: url(bg.png);
    background-repeat:no-repeat;
    background-position:center center;
    background-size:cover;  
}

Below you'll find a complete example that covers both iOS8 and iOS7 (and lower versions). Please note that prior to iOS8 you can't distinguish between "remote notifications disabled" and "only View in lockscreen enabled".

BOOL remoteNotificationsEnabled = false, noneEnabled,alertsEnabled, badgesEnabled, soundsEnabled;

if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    // iOS8+
    remoteNotificationsEnabled = [UIApplication sharedApplication].isRegisteredForRemoteNotifications;

    UIUserNotificationSettings *userNotificationSettings = [UIApplication sharedApplication].currentUserNotificationSettings;

    noneEnabled = userNotificationSettings.types == UIUserNotificationTypeNone;
    alertsEnabled = userNotificationSettings.types & UIUserNotificationTypeAlert;
    badgesEnabled = userNotificationSettings.types & UIUserNotificationTypeBadge;
    soundsEnabled = userNotificationSettings.types & UIUserNotificationTypeSound;

} else {
    // iOS7 and below
    UIRemoteNotificationType enabledRemoteNotificationTypes = [UIApplication sharedApplication].enabledRemoteNotificationTypes;

    noneEnabled = enabledRemoteNotificationTypes == UIRemoteNotificationTypeNone;
    alertsEnabled = enabledRemoteNotificationTypes & UIRemoteNotificationTypeAlert;
    badgesEnabled = enabledRemoteNotificationTypes & UIRemoteNotificationTypeBadge;
    soundsEnabled = enabledRemoteNotificationTypes & UIRemoteNotificationTypeSound;
}

if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    NSLog(@"Remote notifications enabled: %@", remoteNotificationsEnabled ? @"YES" : @"NO");
}

NSLog(@"Notification type status:");
NSLog(@"  None: %@", noneEnabled ? @"enabled" : @"disabled");
NSLog(@"  Alerts: %@", alertsEnabled ? @"enabled" : @"disabled");
NSLog(@"  Badges: %@", badgesEnabled ? @"enabled" : @"disabled");
NSLog(@"  Sounds: %@", soundsEnabled ? @"enabled" : @"disabled");

As already mentioned you can use Fine Code Coverage that visualize coverlet output. If you create a xunit test project (dotnet new xunit) you'll find coverlet reference already present in csproj file because Coverlet is the default coverage tool for every .NET Core and >= .NET 5 applications.

Microsoft has an example using ReportGenerator that converts coverage reports generated by coverlet, OpenCover, dotCover, Visual Studio, NCover, Cobertura, JaCoCo, Clover, gcov or lcov into human readable reports in various formats.

Example report:

While the article focuses on C# and xUnit as the test framework, both MSTest and NUnit would also work.

Guide:

https://docs.microsoft.com/en-us/dotnet/core/testing/unit-testing-code-coverage?tabs=windows#generate-reports

If you want code coverage in .xml files you can run any of these commands:

dotnet test --collect:"XPlat Code Coverage"

dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura

The \ on it's own is used to escape special characters, such as \n (new line), \t (tabulation), \" (quotes) when typing these specific values in a System.out.println() statement.

Thus, if you want to print a backslash, \, you can't have it on it's own since the compiler will be expecting a special character (such as the ones above). Thus, to print a backslash you need to escape it, since itself is also one of these special characters, thus, \\ yields \.

Christoph's answer is perfect. Sometimes however you may want to go more classes up than one. In this case you could try the @at-root and #{} css features which would enable two root classes to sit next to each other using &.

This wouldn't work (due to the nothing before & rule):

container {_x000D_
    background:red;_x000D_
    color:white;_x000D_
    _x000D_
    .desc& {_x000D_
      background: blue;_x000D_
    }_x000D_
_x000D_
    .hello {_x000D_
        padding-left:50px;_x000D_
    }_x000D_
}

But this would (using @at-root plus #{&}):

container {_x000D_
    background:red;_x000D_
    color:white;_x000D_
    _x000D_
    @at-root .desc#{&} {_x000D_
      background: blue;_x000D_
    }_x000D_
_x000D_
    .hello {_x000D_
        padding-left:50px;_x000D_
    }_x000D_
}

You can also use web storage too if the app specs allows you that (it has support for IE8+).

It has 5M (most browsers) or 10M (IE) of memory at its disposal.

"Web Storage (Second Edition)" is the API and "HTML5 Local Storage" is a quick start.

For example two class A,B having same method m1(). And class C extends both A, B.

 class C extends A, B // for explaining purpose.

Now, class C will search the definition of m1. First, it will search in class if it didn't find then it will check to parents class. Both A, B having the definition So here ambiguity occur which definition should choose. So JAVA DOESN'T SUPPORT MULTIPLE INHERITANCE.

You could use a negative look-ahead assertion:

^(?!tbd_).+

Or a negative look-behind assertion:

(^.{1,3}$|^.{4}(?<!tbd_).*)

Or just plain old character sets and alternations:

^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

I also have this problem today. The solution is setting your "ssh key". Click the url below, follow the steps, then you will sovle it.

http://github.com/guides/providing-your-ssh-key

If you doesn't want to touch the config object, you just hide the grid by css:

.chart-container .highcharts-grid {
   display: none;
}

Storage

Given numbers are only for storing 1 character

• ASCII ? 2⁷ bits (1 byte)
• Extended ASCII ? 2⁸ bits (1 byte)
• UTF-8 ? minimum 2⁸, maximum 2³² bits (min 1, max 4 bytes)
• UTF-16 ? minimum 2¹⁶, maximum 2³² bits (min 2, max 4 bytes)
• UTF-32 ? 2³² bits (4 bytes)

Usage (as of Feb 2020)

Note to under

connetionString =@"server=XXX;Trusted_Connection=yes;database=yourDB;";

Note: XXX = . OR .\SQLEXPRESS OR .\MSSQLSERVER OR (local)\SQLEXPRESS OR (localdb)\v11.0 &...

you can replace 'server' with 'Data Source'

too you can replace 'database' with 'Initial Catalog'

Sample:

 connetionString =@"server=.\SQLEXPRESS;Trusted_Connection=yes;Initial Catalog=books;";

If they are in the same controller class, it would be:

foreach ( $characters as $character) {
    $num += $this->getFactorial($index) * $index;
    $index ++;
}

Otherwise you need to create a new instance of the class, and call the method, ie:

$controller = new MyController();
foreach ( $characters as $character) {
    $num += $controller->getFactorial($index) * $index;
    $index ++;
}

This is an example to use ONLY p12 file it's not optimazed but it work. The pkcs12 file where generated by OpenSSL by me. Example how to load p12 file and build Trust zone from it... It outputs certificates from p12 file and add good certs to TrustStore

KeyStore ks=KeyStore.getInstance("pkcs12");
ks.load(new FileInputStream("client_t_c1.p12"),"c1".toCharArray());

KeyStore jks=KeyStore.getInstance("JKS");
jks.load(null);

for (Enumeration<String>t=ks.aliases();t.hasMoreElements();)
{
    String alias = t.nextElement();
    System.out.println("@:" + alias);
    if (ks.isKeyEntry(alias)){
        Certificate[] a = ks.getCertificateChain(alias);
        for (int i=0;i<a.length;i++)
        {
            X509Certificate x509 = (X509Certificate)a[i];
            System.out.println(x509.getSubjectDN().toString());
            if (i>0)
                jks.setCertificateEntry(x509.getSubjectDN().toString(), x509);
            System.out.println(ks.getCertificateAlias(x509));
            System.out.println("ok");
        }
    }
}

System.out.println("init Stores...");

KeyManagerFactory kmf=KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, "c1".toCharArray());

TrustManagerFactory tmf=TrustManagerFactory.getInstance("SunX509");
tmf.init(jks);

SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);

You're probably going to want use a Regular Expression to find the parameter you want to remove from the querystring, then remove it and redirect the browser to the same file with your new querystring.

When you have a more complex id string the double quotes are mandatory.

For example if you have an id like this: id="2.2", the correct way to access it is: $('input[id="2.2"]')

As much as possible use the double quotes, for safety reasons.

For me i tried everything on here and eventually it boiled down to a corporate proxy that kept on resetting the INET Settings.

I worked my way down the list of suggestions but in the end turned out to be the proxy settings. I had hunch about it but i wanted to be thorogh about it before going to 'IT' and saying can i have local bindows proxy settings override please?

I asked for the proxy management software to be removed and then within a second fiddler started working. If you cannot override the proxy settings in Internet Properties then fiddler will never work.

<body> 
    <form method="post">
        name<input type="text" name="text">

    </form>
</body>

Using something like self-clearing div is perfect for a situation like this. Then you'll just use a class on the parent... like:

<div id="parent" class="clearfix">

You must have seen some application that run from the commandline and let you to pass them arguments. If you write one such app in C#, the array args serves as the collection of the said arguments.

This how you process them:

static void Main(string[] args) {
    foreach (string arg in args) {
       //Do something with each argument
    }
}

Set the [Console]::OuputEncoding as encoding whatever you want, and print out with [Console]::WriteLine.

If powershell ouput method has a problem, then don't use it. It feels bit bad, but works like a charm :)

Using Moment library, see their website -> https://momentjs.com/timezone/docs/#/using-timezones/converting-to-zone/

i notice they also user their own library in their website, so you can have a try using the browser console before installing it

moment().tz(String);

The moment#tz mutator will change the time zone and update the offset.

moment("2013-11-18").tz("America/Toronto").format('Z'); // -05:00
moment("2013-11-18").tz("Europe/Berlin").format('Z');   // +01:00

This information is used consistently in other operations, like calculating the start of the day.

var m = moment.tz("2013-11-18 11:55", "America/Toronto");
m.format();                     // 2013-11-18T11:55:00-05:00
m.startOf("day").format();      // 2013-11-18T00:00:00-05:00
m.tz("Europe/Berlin").format(); // 2013-11-18T06:00:00+01:00
m.startOf("day").format();      // 2013-11-18T00:00:00+01:00

Without an argument, moment#tz returns:

    the time zone name assigned to the moment instance or
    undefined if a time zone has not been set.

var m = moment.tz("2013-11-18 11:55", "America/Toronto");
m.tz();  // America/Toronto
var m = moment.tz("2013-11-18 11:55");
m.tz() === undefined;  // true

It selects the next paragraph and indents the beginning of the paragraph from the left just as you might in Microsoft Word.

You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -, like script.ps1 -server http://devserver

Then you handle them in param section in the beginning of the file.

You can also assign default values to your params, read them from console if not available or stop script execution:

 param (
    [string]$server = "http://defaultserver",
    [Parameter(Mandatory=$true)][string]$username,
    [string]$password = $( Read-Host "Input password, please" )
 )

Inside the script you can simply

write-output $server

since all parameters become variables available in script scope.

In this example, the $server gets a default value if the script is called without it, script stops if you omit the -username parameter and asks for terminal input if -password is omitted.

Update: You might also want to pass a "flag" (a boolean true/false parameter) to a PowerShell script. For instance, your script may accept a "force" where the script runs in a more careful mode when force is not used.

The keyword for that is [switch] parameter type:

 param (
    [string]$server = "http://defaultserver",
    [string]$password = $( Read-Host "Input password, please" ),
    [switch]$force = $false
 )

Inside the script then you would work with it like this:

if ($force) {
  //deletes a file or does something "bad"
}

Now, when calling the script you'd set the switch/flag parameter like this:

.\yourscript.ps1 -server "http://otherserver" -force

If you explicitly want to state that the flag is not set, there is a special syntax for that

.\yourscript.ps1 -server "http://otherserver" -force:$false

Had the same issue after installing mysql mariadb 10.3. The password was not NULL so simply pressing ENTER didn't worked for me. So finally had to change the password. I followed instruction from here. In nutshell; stop the server

sudo systemctl stop mariadb.service

gain access to the server through a backdoor by starting the database server and skipping networking and permission tables.

sudo mysqld_safe --skip-grant-tables --skip-networking &

login as root

sudo mysql -u root

then change server password

use mysql;
update user set password=PASSWORD("new_password_here") where User='root';

Note that after MySQL 5.7, the password field in mysql.user table field was removed, now the field name is 'authentication_string'. So use appropriate table name based on mysql version. finally save changes & restart the server

flush privileges;
sudo systemctl stop mariadb.service
sudo systemctl start mariadb.service

Instead of the often suggested SystemChrome.setSystemUIOverlayStyle() which is a system wide service and does not reset on a different route, you can use an AnnotatedRegion<SystemUiOverlayStyle> which is a widget and only has effect for the widget that you wrap.

AnnotatedRegion<SystemUiOverlayStyle>(
   value: SystemUiOverlayStyle(
      statusBarColor: Colors.white,
  ),
  child: Scaffold(
      ...
  ),
)

For fitting y = A + B log x, just fit y against (log x).

>>> x = numpy.array([1, 7, 20, 50, 79])
>>> y = numpy.array([10, 19, 30, 35, 51])
>>> numpy.polyfit(numpy.log(x), y, 1)
array([ 8.46295607,  6.61867463])
# y ˜ 8.46 log(x) + 6.62

For fitting y = Ae^Bx, take the logarithm of both side gives log y = log A + Bx. So fit (log y) against x.

Note that fitting (log y) as if it is linear will emphasize small values of y, causing large deviation for large y. This is because polyfit (linear regression) works by minimizing ?_i (?Y)² = ?_i (Y_i − Y_i)². When Y_i = log y_i, the residues ?Y_i = ?(log y_i) ˜ ?y_i / |y_i|. So even if polyfit makes a very bad decision for large y, the "divide-by-|y|" factor will compensate for it, causing polyfit favors small values.

This could be alleviated by giving each entry a "weight" proportional to y. polyfit supports weighted-least-squares via the w keyword argument.

>>> x = numpy.array([10, 19, 30, 35, 51])
>>> y = numpy.array([1, 7, 20, 50, 79])
>>> numpy.polyfit(x, numpy.log(y), 1)
array([ 0.10502711, -0.40116352])
#    y ˜ exp(-0.401) * exp(0.105 * x) = 0.670 * exp(0.105 * x)
# (^ biased towards small values)
>>> numpy.polyfit(x, numpy.log(y), 1, w=numpy.sqrt(y))
array([ 0.06009446,  1.41648096])
#    y ˜ exp(1.42) * exp(0.0601 * x) = 4.12 * exp(0.0601 * x)
# (^ not so biased)

Note that Excel, LibreOffice and most scientific calculators typically use the unweighted (biased) formula for the exponential regression / trend lines. If you want your results to be compatible with these platforms, do not include the weights even if it provides better results.

Now, if you can use scipy, you could use scipy.optimize.curve_fit to fit any model without transformations.

For y = A + B log x the result is the same as the transformation method:

>>> x = numpy.array([1, 7, 20, 50, 79])
>>> y = numpy.array([10, 19, 30, 35, 51])
>>> scipy.optimize.curve_fit(lambda t,a,b: a+b*numpy.log(t),  x,  y)
(array([ 6.61867467,  8.46295606]), 
 array([[ 28.15948002,  -7.89609542],
        [ -7.89609542,   2.9857172 ]]))
# y ˜ 6.62 + 8.46 log(x)

For y = Ae^Bx, however, we can get a better fit since it computes ?(log y) directly. But we need to provide an initialize guess so curve_fit can reach the desired local minimum.

>>> x = numpy.array([10, 19, 30, 35, 51])
>>> y = numpy.array([1, 7, 20, 50, 79])
>>> scipy.optimize.curve_fit(lambda t,a,b: a*numpy.exp(b*t),  x,  y)
(array([  5.60728326e-21,   9.99993501e-01]),
 array([[  4.14809412e-27,  -1.45078961e-08],
        [ -1.45078961e-08,   5.07411462e+10]]))
# oops, definitely wrong.
>>> scipy.optimize.curve_fit(lambda t,a,b: a*numpy.exp(b*t),  x,  y,  p0=(4, 0.1))
(array([ 4.88003249,  0.05531256]),
 array([[  1.01261314e+01,  -4.31940132e-02],
        [ -4.31940132e-02,   1.91188656e-04]]))
# y ˜ 4.88 exp(0.0553 x). much better.

@RequestBody MultipartFile[] submissions

should be

@RequestParam("file") MultipartFile[] submissions

The files are not the request body, they are part of it and there is no built-in HttpMessageConverter that can convert the request to an array of MultiPartFile.

You can also replace HttpServletRequest with MultipartHttpServletRequest, which gives you access to the headers of the individual parts.

Edit 2020: This does not work any more. It seems so, that the browser vendors patched this out. Because the most browsers rely on chromium, it might be in its core.

Old answer: You can also hook mouseenter (this event is fired after page reload, when the mousecursor is inside the page). Extending Corrupted's code should do the trick:

var x = null;_x000D_
var y = null;_x000D_
    _x000D_
document.addEventListener('mousemove', onMouseUpdate, false);_x000D_
document.addEventListener('mouseenter', onMouseUpdate, false);_x000D_
    _x000D_
function onMouseUpdate(e) {_x000D_
  x = e.pageX;_x000D_
  y = e.pageY;_x000D_
  console.log(x, y);_x000D_
}_x000D_
_x000D_
function getMouseX() {_x000D_
  return x;_x000D_
}_x000D_
_x000D_
function getMouseY() {_x000D_
  return y;_x000D_
}

You can also set x and y to null on mouseleave-event. So you can check if the user is on your page with it's cursor.

Try This

<button class="click_on_enterkey" type="button" onclick="return false;">
<script>
$('.click_on_enterkey').on('keyup',function(event){
  if(event.keyCode == 13){
    $(this).click();
  }
});
<script>

You actually had it correct in your third attempt.

 <select ng-model="myselect" ng-options="o as o for o in options"></select>

See a working example here: http://plnkr.co/edit/xEERH2zDQ5mPXt9qCl6k?p=preview

The trick is that AngularJS writes the keys as numbers from 0 to n anyway, and translates back when updating the model.

As a result, the HTML will look incorrect but the model will still be set properly when choosing a value. (i.e. AngularJS will translate '0' back to 'var1')

The solution by Epokk also works, however if you're loading data asynchronously you might find it doesn't always update correctly. Using ngOptions will correctly refresh when the scope changes.

(In Kotlin) If you are going to put the answer into a TextView or something you can instead use a string resource:

<string name="time">%02d:%02d</string>

And then you can use this String resource to then set the text at run time using:

private fun setTime(time: Int) {
    val hour = time / 60
    val min = time % 60
    main_time.text = getString(R.string.time, hour, min)
}

try this

 alert(document.getElementById("dropDownMenuKategorie").selectedIndex);

To check if a float value is a whole number, use the float.is_integer() method:

>>> (1.0).is_integer()
True
>>> (1.555).is_integer()
False

The method was added to the float type in Python 2.6.

Take into account that in Python 2, 1/3 is 0 (floor division for integer operands!), and that floating point arithmetic can be imprecise (a float is an approximation using binary fractions, not a precise real number). But adjusting your loop a little this gives:

>>> for n in range(12000, -1, -1):
...     if (n ** (1.0/3)).is_integer():
...         print n
... 
27
8
1
0

which means that anything over 3 cubed, (including 10648) was missed out due to the aforementioned imprecision:

>>> (4**3) ** (1.0/3)
3.9999999999999996
>>> 10648 ** (1.0/3)
21.999999999999996

You'd have to check for numbers close to the whole number instead, or not use float() to find your number. Like rounding down the cube root of 12000:

>>> int(12000 ** (1.0/3))
22
>>> 22 ** 3
10648

If you are using Python 3.5 or newer, you can use the math.isclose() function to see if a floating point value is within a configurable margin:

>>> from math import isclose
>>> isclose((4**3) ** (1.0/3), 4)
True
>>> isclose(10648 ** (1.0/3), 22)
True

For older versions, the naive implementation of that function (skipping error checking and ignoring infinity and NaN) as mentioned in PEP485:

def isclose(a, b, rel_tol=1e-9, abs_tol=0.0):
    return abs(a - b) <= max(rel_tol * max(abs(a), abs(b)), abs_tol)

There is no way to delete or read the past history.

You could try going around it by emulating history in your own memory and calling history.pushState everytime window popstate event is emitted (which is proposed by the currently accepted Mike's answer), but it has a lot of disadvantages that will result in even worse UX than not supporting the browser history at all in your dynamic web app, because:

• popstate event can happen when user goes back ~2-3 states to the past
• popstate event can happen when user goes forward

So even if you try going around it by building virtual history, it's very likely that it can also lead into a situation where you have blank history states (to which going back/forward does nothing), or where that going back/forward skips some of your history states totally.

You can do the following which escapes both PHP and MySQL.

<?
$text = '<a href="javascript:window.open(\\\'http://www.google.com\\\');"></a>';
?> 

This will reflect MySQL as

<a href="javascript:window.open('http://www.google.com');"></a>

How does it work?

We know that both PHP and MySQL apostrophes can be escaped with backslash and then apostrophe.

\'

Because we are using PHP to insert into MySQL, we need PHP to still write the backslash to MySQL so it too can escape it. So we use the PHP escape character of backslash-backslash together with backslash-apostrophe to achieve this.

I used Mosh's solution, but it was not obvious to me how to implement the composition key correctly in code first.

So here is the solution:

public class Holiday
{
    [Key, Column(Order = 0), DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int HolidayId { get; set; }
    [Key, Column(Order = 1), ForeignKey("Location")]
    public LocationEnum LocationId { get; set; }

    public virtual Location Location { get; set; }

    public DateTime Date { get; set; }
    public string Name { get; set; }
}

If you don't want to use dangerouslySetInnerHTML then you can use the below mentioned solution

var Iframe = React.createClass({     
  render: function() {
    return(         
      <div>          
        <iframe src={this.props.src} height={this.props.height} width={this.props.width}/>         
      </div>
    )
  }
});

ReactDOM.render(
  <Iframe src="http://plnkr.co/" height="500" width="500"/>,
  document.getElementById('example')

No. Python Strings are immutable.

Visual Studio Community 2015 suffices to build extensions for Python 3.5. It's free but a 6 GB download (overkill). On my computer it installed vcvarsall at C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat

For Python 3.4 you'd need Visual Studio 2010. I don't think there's any free edition. See https://matthew-brett.github.io/pydagogue/python_msvc.html

Without using external tools, if you are connecting to the server view SSH, this is a relatively easy command:

From a Windows 7+ command prompt:

ssh user@server cat /etc/passwd | clip

This will put the content of the remote file to your local clipboard.

(The command requires running Pageant for the key, or it will ask you for a password.)

I would suggest using numpy's sort, as it is anyway what pandas is doing in background:

import numpy as np
np.sort(df.A.unique())

But doing all in pandas is valid as well.

Using unless is fine for statements with single include? clauses but, for example, when you need to check the inclusion of something in one Array but not in another, the use of include? with exclude? is much friendlier.

if @players.include? && @spectators.exclude? do
  ....
end

But as dizzy42 says above, the use of exclude? requires ActiveSupport

The best thing to do is to install the Tampermonkey extension.

This will allow you to easily install Greasemonkey scripts, and to easily manage them. Also it makes it easier to install userscripts directly from sites like OpenUserJS, MonkeyGuts, etc.

Finally, it unlocks most all of the GM functionality that you don't get by installing a GM script directly with Chrome. That is, more of what GM on Firefox can do, is available with Tampermonkey.

But, if you really want to install a GM script directly, it's easy a right pain on Chrome these days...

Chrome After about August, 2014:

You can still drag a file to the extensions page and it will work... Until you restart Chrome. Then it will be permanently disabled. See Continuing to "protect" Chrome users from malicious extensions for more information. Again, Tampermonkey is the smart way to go. (Or switch browsers altogether to Opera or Firefox.)

Chrome 21+ :

Chrome is changing the way extensions are installed. Userscripts are pared-down extensions on Chrome but. Starting in Chrome 21, link-click behavior is disabled for userscripts. To install a user script, drag the **.user.js* file into the Extensions page (chrome://extensions in the address input).

Older Chrome versions:

Merely drag your **.user.js* files into any Chrome window. Or click on any Greasemonkey script-link.

You'll get an installation warning:

Click Continue.

You'll get a confirmation dialog:

Click Add.

Notes:

1. Scripts installed this way have limitations compared to a Greasemonkey (Firefox) script or a Tampermonkey script. See Cross-browser user-scripting, Chrome section.

Controlling the Script and name:

By default, Chrome installs scripts in the Extensions folder¹, full of cryptic names and version numbers. And, if you try to manually add a script under this folder tree, it will be wiped the next time Chrome restarts.

To control the directories and filenames to something more meaningful, you can:

1. Create a directory that's convenient to you, and not where Chrome normally looks for extensions. For example, Create: C:\MyChromeScripts\.

2. For each script create its own subdirectory. For example, HelloWorld.

3. In that subdirectory, create or copy the script file. For example, Save this question's code as: HelloWorld.user.js.

4. You must also create a manifest file in that subdirectory, it must be named: manifest.json.

   For our example, it should contain:

   {
       "manifest_version": 2,
       "content_scripts": [ {
           "exclude_globs":    [  ],
           "include_globs":    [ "*" ],
           "js":               [ "HelloWorld.user.js" ],
           "matches":          [   "https://stackoverflow.com/*",
                                   "https://stackoverflow.com/*"
                               ],
           "run_at": "document_end"
       } ],
       "converted_from_user_script": true,
       "description":  "My first sensibly named script!",
       "name":         "Hello World",
       "version":      "1"
   }
   

   The manifest.json file is automatically generated from the meta-block by Chrome, when an user script is installed. The values of @include and @exclude meta-rules are stored in include_globs and exclude_globs, @match (recommended) is stored in the matches list. "converted_from_user_script": true is required if you want to use any of the supported GM_* methods.

5. Now, in Chrome's Extension manager (URL = chrome://extensions/), Expand "Developer mode".

6. Click the Load unpacked extension... button.

7. For the folder, paste in the folder for your script, In this example it is: C:\MyChromeScripts\HelloWorld.

8. Your script is now installed, and operational!

9. If you make any changes to the script source, hit the Reload link for them to take effect:

   

¹ The folder defaults to:

Windows XP:
  Chrome  : %AppData%\..\Local Settings\Application Data\Google\Chrome\User Data\Default\Extensions\
  Chromium: %AppData%\..\Local Settings\Application Data\Chromium\User Data\Default\Extensions\

Windows Vista/7/8:
  Chrome  : %LocalAppData%\Google\Chrome\User Data\Default\Extensions\
  Chromium: %LocalAppData%\Chromium\User Data\Default\Extensions\

Linux:
  Chrome  : ~/.config/google-chrome/Default/Extensions/
  Chromium: ~/.config/chromium/Default/Extensions/

Mac OS X:
  Chrome  : ~/Library/Application Support/Google/Chrome/Default/Extensions/
  Chromium: ~/Library/Application Support/Chromium/Default/Extensions/

Although you can change it by running Chrome with the --user-data-dir= option.

Use a combination of of fopen, fwrite and fread. PHP.net has excellent documentation and examples of each of them.

http://us2.php.net/manual/en/function.fread.php

The problem could be that the Python libraries, per HTTP-Standard, first send an unauthenticated request, and then only if it's answered with a 401 retry, are the correct credentials sent. If the Foursquare servers don't do "totally standard authentication" then the libraries won't work.

Try using headers to do authentication:

import urllib2, base64

request = urllib2.Request("http://api.foursquare.com/v1/user")
base64string = base64.b64encode('%s:%s' % (username, password))
request.add_header("Authorization", "Basic %s" % base64string)   
result = urllib2.urlopen(request)

Had the same problem as you and found the solution from this thread: http://forums.shopify.com/categories/9/posts/27662

You can do it with a simple jquery code.

$('#Mymodal').modal('hide');

If you are using the package device_id to get the unique device id then that will add an android.permission.READ_PHONE_STATE without your knowledge which eventually will lead to the Play Store warning.

Instead you can use the device_info package for the same purpose without the need of the extra permission. Check this SO thread

Better approach may be a polyfill like this

jQuery.fn.load = function(callback){ $(window).on("load", callback) };

With this you can leave the legacy code untouched. If you use webpack be sure to use script-loader.

Options and dependencies need to be inside arrays:

namespace :thing do
  desc "it does a thing"
  task :work, [:option, :foo, :bar] do |task, args|
    puts "work", args
  end
  
  task :another, [:option, :foo, :bar] do |task, args|
    puts "another #{args}"
    Rake::Task["thing:work"].invoke(args[:option], args[:foo], args[:bar])
    # or splat the args
    # Rake::Task["thing:work"].invoke(*args)
  end

end

Then

rake thing:work[1,2,3]
=> work: {:option=>"1", :foo=>"2", :bar=>"3"}

rake thing:another[1,2,3]
=> another {:option=>"1", :foo=>"2", :bar=>"3"}
=> work: {:option=>"1", :foo=>"2", :bar=>"3"}

NOTE: variable task is the task object, not very helpful unless you know/care about Rake internals.

RAILS NOTE:

If running the task from Rails, it's best to preload the environment by adding => [:environment] which is a way to setup dependent tasks.

  task :work, [:option, :foo, :bar] => [:environment] do |task, args|
    puts "work", args
  end

The var keyword in C#'s main benefit is to enhance readability, not functionality. Technically, the var keywords allows for some other unlocks (e.g. use of anonymous objects), but that seems to be outside the scope of this question. Every variable declared with the var keyword has a type. For instance, you'll find that the following code outputs "String".

var myString = "";
Console.Write(myString.GetType().Name);

Furthermore, the code above is equivalent to:

String myString = "";
Console.Write(myString.GetType().Name);

The var keyword is simply C#'s way of saying "I can figure out the type for myString from the context, so don't worry about specifying the type."

var myVariable = (MyType)null or MyType myVariable = null should work because you are giving the C# compiler context to figure out what type myVariable should will be.

Check for the mongo version of the client from where we are connecting to mongo server.

My case, mongo server was of version Mongo4.0.0 but my client was of version 2.4.9. Update the mongo version to update mongo cli.
