Doing

SET FOREIGN_KEY_CHECKS=0;

before the Operation can also do the trick.

There is a syntax problem, because the right syntax to alter command is ALTER TABLE tablename CHANGE OldColumnName NewColunmName DATATYPE;

For those who are getting to this question via google... this error can also happen if you try to rename a field that is acting as a foreign key.

Try this:

alter table Documents drop
  FK__Documents__Custo__2A4B4B5E

You can use axis:

> axis(side=1, at=c(0:23))

That is, something like this:

plot(0:23, d, type='b', axes=FALSE)
axis(side=1, at=c(0:23))
axis(side=2, at=seq(0, 600, by=100))
box()

For those working in Visual Studio simply add the include, Lib and libs directories to the Include Directories and Library Directories under Projects Properties -> Configuration Properties > VC++ Directories :

For example I have Anaconda3 on my system and working with Visual Studio 2015 This is how the settings looks like (note the Include and Library directories) :

Edit:

As also pointed out by bossi setting PYTHONPATH in your user Environment Variables section seems necessary. a sample input can be like this (in my case):

C:\Users\Master\Anaconda3\Lib;C:\Users\Master\Anaconda3\libs;C:\Users\Master\Anaconda3\Lib\site-packages;C:\Users\Master\Anaconda3\DLLs

is necessary it seems.

Also, you need to restart Visual Studio after you set up the PYTHONPATH in your user Environment Variables for the changes to take effect.

Also note that :

Make sure the PYTHONHOME environment variable is set to the Python interpreter you want to use. The C++ projects in Visual Studio rely on this variable to locate files such as python.h, which are used when creating a Python extension.

In the case of Linux, You get the version of Android SDK using sdkmanager.

your_path/android-sdk/tools/bin/sdkmanager --version

in my case

/var/lib/jenkins/android-sdk/tools/bin/sdkmanager --version

If you want the margin-left to work on a span element you'll need to make it display: inline-block or display:block as well.

use:

<div class="row form-group"></div>

Here is an updated version for Chart.js 2.3

Sep 23, 2016: Edited my code to work with v2.3 for both line/bar type.

If you have PHP installed on your server, you can chek it in runtime using "extension_loaded" funciontion. Just like this:

<?php
if (!extension_loaded('openssl')) {
    // no openssl extension loaded.
}
?>

This gives you the needed results:

string time = "16:23:01";
var result = Convert.ToDateTime(time);
string test = result.ToString("hh:mm:ss tt", CultureInfo.CurrentCulture);
//This gives you "04:23:01 PM"  string

You could also use CultureInfo.CreateSpecificCulture("en-US") as not all cultures will display AM/PM.

You're probably trying to to update the same row of the target table multiple times. I just encountered the very same problem in a merge statement I developed. Make sure your update does not touch the same record more than once in the execution of the merge.

IE displays a active x warning and ask for permission if you allow it to run or not. To overcome this the only solution is to;

1. Open Internet Explorer.
2. Click the Tools menu, and then click Internet Options.
3. On the Security tab, click the Custom level button.
4. Scroll down the Security Settings list until you see ActiveX controls and plug-ins.
5. For Automatic prompting for ActiveX controls, click Enable.
6. Scroll down to Download signed ActiveX controls and click Enable or Prompt.
7. Scroll down to Run ActiveX controls and plug-ins and click Enable or Prompt.
8. Scroll down to Script ActiveX controls marked safe for scripting and click Enable or Prompt.
9. Click OK, and then click OK again.

There is no way to overcome this issue except changing manually Internet explorer settings. Try checking if plugin works fine while changed settings. If its still not working or not showing any warning is display try checking console for other errors which are not related to active x. Good luck!

A UDF will only return a value it won't allow you to change the properties of a cell/sheet/workbook. Move your code to a Worksheet_Change event or similar to change properties.

Eg

Private Sub worksheet_change(ByVal target As Range)
  target.Font.Bold = True
End Sub

First add an Enrty and Category class:

public class Entry {     public string Id { get; set; }     public string Title { get; set; }     public string Updated { get; set; }     public string Summary { get; set; }     public string GPoint { get; set; }     public string GElev { get; set; }     public List<string> Categories { get; set; } }  public class Category {     public string Label { get; set; }     public string Term { get; set; } } 

Then use LINQ to XML

XDocument xDoc = XDocument.Load("path");          List<Entry> entries = (from x in xDoc.Descendants("entry")             select new Entry()             {                 Id = (string) x.Element("id"),                 Title = (string)x.Element("title"),                 Updated = (string)x.Element("updated"),                 Summary = (string)x.Element("summary"),                 GPoint = (string)x.Element("georss:point"),                 GElev = (string)x.Element("georss:elev"),                 Categories = (from c in x.Elements("category")                                   select new Category                                   {                                       Label = (string)c.Attribute("label"),                                       Term = (string)c.Attribute("term")                                   }).ToList();             }).ToList(); 

Basically http.antMatcher() tells Spring to only configure HttpSecurity if the path matches this pattern.

It doesn't work if you use Function, but works if you Sub. However, you cannot call a sub from a cell using formula.

I got the same exception also, but it was previously running fine in another machine. Anyway above solution didn't worked for me. What i did to resolve it?

1. Copy dependencies list into clipboard.
2. enter "npm init" to create fresh new package.json
3. Paste the dependencies again back to package.json
4. run "npm install" again!

Done :) Hope it helps.

Here is how I do that using moment:

  let today = moment().format('DD MMMM YYYY');

  let tomorrow = moment().add(1, 'days').format('DD MMMM YYYY').toString();

  let yesterday = moment().subtract(1, 'days').startOf('day').format('DD MMMM YYYY').toString();

You can't currently animate on height when one of the heights involved is auto, you have to set two explicit heights.

From the comment by @ZhekaKozlov: ojdkbuild has OpenJDK builds (currently 8 and 11) for Windows (zip and msi).

Another possibility is:

d = datetime.datetime.utcnow()
epoch = datetime.datetime(1970,1,1)
t = (d - epoch).total_seconds()

This works as both "d" and "epoch" are naive datetimes, making the "-" operator valid, and returning an interval. total_seconds() turns the interval into seconds. Note that total_seconds() returns a float, even d.microsecond == 0

In order to set the ImageView and Height Programatically, you can do

            //Makesure you calculate the density pixel and multiply it with the size of width/height
            float dpCalculation = getResources().getDisplayMetrics().density;
            your_imageview.getLayoutParams().width = (int) (150 * dpCalculation);

            //Set ScaleType according to your choice...
            your_imageview.setScaleType(ImageView.ScaleType.CENTER_CROP);

Try using autocomplete="off". Not sure if every browser supports it, though. MSDN docs here.

EDIT: Note: most browsers have dropped support for this attribute. See Is autocomplete="off" compatible with all modern browsers?

This is arguably something that should be left up to the user rather than the web site designer.

I hope this would be helpful:

.top_image img{
display: block;
margin: 0 auto;
}

This is a Python solution.

You can easily debug such things when you go through the generated CSS. In this case the pseudo-selector after conversion has to be attached to the class. Which is not the case. Use "&".

http://sass-lang.com/documentation/file.SASS_REFERENCE.html#parent-selector

.class {
    margin:20px;
    &:hover {
        color:yellow;

Expanding a bit on @Eruant's answer,

$(window).on('load', function() {
    // your code here
});

Works very well with both async and defer while loading on scripts.

So you can import all scripts like this:

<script src="/js/script1.js" async defer></script>
<script src="/js/script2.js" async defer></script>
<script src="/js/script3.js" async defer></script>

Just make sure script1 doesn't call functions from script3 before $(window).on('load' ..., make sure to call them inside window load event.

More about async/defer here.

The type attribute is used to define the MIME type within the HTML document. Depending on what DOCTYPE you use, the type value is required in order to validate the HTML document.

The language attribute lets the browser know what language you are using (Javascript vs. VBScript) but is not necessarily essential and, IIRC, has been deprecated.

IP can be any LAN or WAN IP address. But you'll want to set your firewall connection allow it.

Device connection with webserver pc can be by LAN or WAN (i.e by wifi, connectify, adhoc, cable, mypublic wifi etc)

You should follow these steps:

1. Go to the control panel
2. Inbound rules > new rules
3. Click port > next > specific local port > enter 8080 > next > allow the connection>
4. Next > tick all (domain, private, public) > specify any name
5. Now you can access your localhost by any device (laptop, mobile, desktop, etc).
6. Enter ip address in browser url as 123.23.xx.xx:8080 to access localhost by any device.

This IP will be of that device which has the web server.

If the culture of the result doesn't matters or we're only talking of integer values, CONVERT or CAST will be fine.

However, if the result must match a specific culture, FORMAT might be the function to go:

DECLARE @value DECIMAL(19,4) = 1505.5698
SELECT CONVERT(NVARCHAR, @value)        -->  1505.5698
SELECT FORMAT(@value, 'N2', 'en-us')    --> 1,505.57
SELECT FORMAT(@value, 'N2', 'de-de')    --> 1.505,57

For more information on FORMAT see here.

Of course, formatting the result should be a matter of the UI layer of the software.

Unfortunately, this is not possible. Per the spec:

Generated content does not alter the document tree. In particular, it is not fed back to the document language processor (e.g., for reparsing).

In other words, for string values this means the value is always treated literally. It is never interpreted as markup, regardless of the document language in use.

As an example, using the given CSS with the following HTML:

<h1 class="header">Title</h1>

... will result in the following output:

<a href="#top">Back</a>Title

Spring exposes the current HttpServletRequest object (as well as the current HttpSession object) through a wrapper object of type ServletRequestAttributes. This wrapper object is bound to ThreadLocal and is obtained by calling the static method RequestContextHolder.currentRequestAttributes().

ServletRequestAttributes provides the method getRequest() to get the current request, getSession() to get the current session and other methods to get the attributes stored in both the scopes. The following code, though a bit ugly, should get you the current request object anywhere in the application:

HttpServletRequest curRequest = 
((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes())
.getRequest();

Note that the RequestContextHolder.currentRequestAttributes() method returns an interface and needs to be typecasted to ServletRequestAttributes that implements the interface.

Well, Even I tried to log in with the admin/password which was failed. So I created my own user like this.

1. Go to Jenkins home folder (C:\User.jenkins or you can find this in Jenkins server startup logs)
2. Go to Config file config.xml
3. set disableSignup to false false if at all you want to disable login security 4.set ser security to false. true

Since git is a distributed version control system, the difference is that commit will commit changes to your local repository, whereas push will push changes up to a remote repo.

SELECT DATEDIFF( now(), '2013-06-20' );

here datediff takes two arguments 'upto-date', 'from-date'

What i have done is, using now() function, i can get no. of days since 20-june-2013 till today.

• In your app.component.html use:

    [ngStyle]="{'background-color':backcolor}"
  

• In app.ts declare variable of string type backcolor:string.

• Set the variable this.backcolor="red".

I would go like this (regex explained in comments):

import re

# If you need to use the regex more than once it is suggested to compile it.
pattern = re.compile(r"</{0,}\[\d+>")

# <\/{0,}\[\d+>
# 
# Match the character “<” literally «<»
# Match the character “/” literally «\/{0,}»
#    Between zero and unlimited times, as many times as possible, giving back as needed (greedy) «{0,}»
# Match the character “[” literally «\[»
# Match a single digit 0..9 «\d+»
#    Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
# Match the character “>” literally «>»

subject = """this is a paragraph with<[1> in between</[1> and then there are cases ... where the<[99> number ranges from 1-100</[99>. 
and there are many other lines in the txt files
with<[3> such tags </[3>"""

result = pattern.sub("", subject)

print(result)

git stash apply n

works as of git version 2.11

Original answer, possibly helping to debug issues with the older syntax involving shell escapes:

As pointed out previously, the curly braces may require escaping or quoting depending on your OS, shell, etc.

See "stash@{1} is ambiguous?" for some detailed hints of what may be going wrong, and how to work around it in various shells and platforms.

git stash list
git stash apply stash@{n}

git stash apply version

You can use format:

library(zoo)
x <- as.yearmon(Sys.time())
format(x,"%b")
[1] "Mar"
format(x,"%Y")
[1] "2012"

When in doubt, follow MVC conventions.

Create a viewModel if you haven't already that contains a property for JobID

public class Model
{
     public string JobId {get; set;}
     public IEnumerable<MyCurrentModel> myCurrentModel { get; set; }
     //...any other properties you may need
}

Strongly type your view

@model Fully.Qualified.Path.To.Model

Add a hidden field for JobId to the form

using (@Html.BeginForm("myMethod", "Home", FormMethod.Post))
{   
    //...    
    @Html.HiddenFor(m => m.JobId)
}

And accept the model as the parameter in your controller action:

[HttpPost]
public FileStreamResult myMethod(Model model)
{
    sting str = model.JobId;
}

Cleartext is any transmitted or stored information that is not encrypted or meant to be encrypted.

When an app communicates with servers using a cleartext network traffic, such as HTTP (not https), it could raise the risk of hacking and tampering of content. Third parties can inject unauthorized data or leak information about the users. That is why developers are encouraged to secure traffic only, such as HTTPS. Here is the implementation and the reference of how to resolve this problem.

boost::timer will probably give you as much accuracy as you'll need. It's nowhere near accurate enough to tell you how long a = a+1; will take, but I what reason would you have to time something that takes a couple nanoseconds?

First you have to ensure that there is a SMTP server listening on port 25.

To look whether you have the service, you can try using TELNET client, such as:

C:\> telnet localhost 25

(telnet client by default is disabled on most recent versions of Windows, you have to add/enable the Windows component from Control Panel. In Linux/UNIX usually telnet client is there by default.

$ telnet localhost 25

If it waits for long then time out, that means you don't have the required SMTP service. If successfully connected you enter something and able to type something, the service is there.

If you don't have the service, you can use these:

• A mock SMTP server that will mimic the behavior of actual SMTP server, as you are using Java, it is natural to suggest Dumbster fake SMTP server. This even can be made to work within JUnit tests (with setup/tear down/validation), or independently run as separate process for integration test.
• If your host is Windows, you can try installing Mercury email server (also comes with WAMPP package from Apache Friends) on your local before running above code.
• If your host is Linux or UNIX, try to enable the mail service such as Postfix,
• Another full blown SMTP server in Java, such as Apache James mail server.

If you are sure that you already have the service, may be the SMTP requires additional security credentials. If you can tell me what SMTP server listening on port 25 I may be able to tell you more.

This has been working for me:

1. Create your war file (mysite.war) locally.
2. Rename it locally to something besides .war, like mysite.www
3. With tomcat still running, upload mysite.www to webapps directory.
4. After it finishes uploading, delete the previous version mysite.war
5. List the directory, watching for the directory /mysite to disappear.
6. Rename mysite.www to be mysite.war
7. List the directory, watching for the new /mysite to be created.

If you try uploading the new file as a war file, with tomcat still running, it will attempt to expand it before it is all there. It will fail. Having failed, it will not try again. Thus, uploading a www file, then renaming it, allows the whole war file to be present before tomcat notices it.

Hint, don't forget to check that the war file's owner is tomcat (Use chown)

it means ONLY one byte will be allocated per character - so if you're using multi-byte charsets, your 1 character won't fit

if you know you have to have at least room enough for 1 character, don't use the BYTE syntax unless you know exactly how much room you'll need to store that byte

when in doubt, use VARCHAR2(1 CHAR)

same thing answered here Difference between BYTE and CHAR in column datatypes

Also, in 12c the max for varchar2 is now 32k, not 4000. If you need more than that, use CLOB

in Oracle, don't use VARCHAR

Use ConfigParser.

Your config:

[myvars]
var_a: 'home'
var_b: 'car'
var_c: 15.5

Your python code:

import ConfigParser

config = ConfigParser.ConfigParser()
config.read("config.ini")
var_a = config.get("myvars", "var_a")
var_b = config.get("myvars", "var_b")
var_c = config.get("myvars", "var_c")

What HIVE can do which is not possible in PIG?

Partitioning can be done using HIVE but not in PIG, it is a way of bypassing the output.

What PIG can do which is not possible in HIVE?

Positional referencing - Even when you dont have field names, we can reference using the position like $0 - for first field, $1 for second and so on.

And another fundamental difference is, PIG doesn't need a schema to write the values but HIVE does need a schema.

You can connect from any external application to HIVE using JDBC and others but not with PIG.

Note: Both runs on top of HDFS (hadoop distributed file system) and the statements are converted to Map Reduce programs.

have a look at http://au.php.net/reserved.variables

I think the variable you are looking for is: $_SERVER["DOCUMENT_ROOT"]

In Java, a two-dimensional array can be declared as the same as a one-dimensional array. In a one-dimensional array you can write like

  int array[] = new int[5];

where int is a data type, array[] is an array declaration, and new array is an array with its objects with five indexes.

Like that, you can write a two-dimensional array as the following.

  int array[][];
  array = new int[3][4];

Here array is an int data type. I have firstly declared on a one-dimensional array of that types, then a 3 row and 4 column array is created.

In your code

int[][] multD = new int[5][];
multD[0] = new int[10];

means that you have created a two-dimensional array, with five rows. In the first row there are 10 columns. In Java you can select the column size for every row as you desire.

Here are some more console logging "pro tips":

console.table

var animals = [
    { animal: 'Horse', name: 'Henry', age: 43 },
    { animal: 'Dog', name: 'Fred', age: 13 },
    { animal: 'Cat', name: 'Frodo', age: 18 }
];

console.table(animals);

console.trace

Shows you the call stack for leading up to the console.

You can even customise your consoles to make them stand out

console.todo = function(msg) {
    console.log(‘ % c % s % s % s‘, ‘color: yellow; background - color: black;’, ‘–‘, msg, ‘–‘);
}

console.important = function(msg) {
    console.log(‘ % c % s % s % s’, ‘color: brown; font - weight: bold; text - decoration: underline;’, ‘–‘, msg, ‘–‘);
}

console.todo(“This is something that’ s need to be fixed”);
console.important(‘This is an important message’);

If you really want to level up don't limit your self to the console statement.

Here is a great post on how you can integrate a chrome debugger right into your code editor!

https://hackernoon.com/debugging-react-like-a-champ-with-vscode-66281760037

I do always this:

from h in OH
where h.Hierarchy.Contains("/12/")
select h

I know I don't use the like statement but it's work fine in the background is this translated into a query with a like statement.

Using direct conditions (like ==, !=, !condition) will have a slight performance improvement over the .equals(condition) as in one case you are calling the method from an object whereas direct comparisons are performed directly.

As above mentioned, there is no special command to do it. However, if all those connection are inactive, using 'flush tables;' is able to release all those connection which are not active.

Another way simpler than me has worked with SQL Developer 4 in Windows 7

spool "path_to_file\\filename.txt"
query to execute
spool of

You have to execute it as a script, because if not only the query will be saved in the output file In the path name I use the double character "\" as a separator when working with Windows and SQL, The output file will display the query and the result.

Depends on what your definition of "offscreen" is. Is that within the viewport, or within the defined boundaries of your page?

Using Element.getBoundingClientRect() you can easily detect whether or not your element is within the boundries of your viewport (i.e. onscreen or offscreen):

jQuery.expr.filters.offscreen = function(el) {
  var rect = el.getBoundingClientRect();
  return (
           (rect.x + rect.width) < 0 
             || (rect.y + rect.height) < 0
             || (rect.x > window.innerWidth || rect.y > window.innerHeight)
         );
};

You could then use that in several ways:

// returns all elements that are offscreen
$(':offscreen');

// boolean returned if element is offscreen
$('div').is(':offscreen');

It is because you haven't qualified Cells(1, 1) with a worksheet object, and the same holds true for Cells(10, 2). For the code to work, it should look something like this:

Dim ws As Worksheet

Set ws = Sheets("SheetName")
Range(ws.Cells(1, 1), ws.Cells(10, 2)).ClearContents

Alternately:

With Sheets("SheetName")
    Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With

EDIT: The Range object will inherit the worksheet from the Cells objects when the code is run from a standard module or userform. If you are running the code from a worksheet code module, you will need to qualify Range also, like so:

ws.Range(ws.Cells(1, 1), ws.Cells(10, 2)).ClearContents

or

With Sheets("SheetName")
    .Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With

PixlUI project allows you to use textAllCaps in any textview or subclass of textview including: Button, EditText AutoCompleteEditText Checkbox RadioButton and several others.

You will need to create your textviews using the pixlui version rather than the ones from the android source, meaning you have to do this:

<com.neopixl.pixlui.components.textview.TextView

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world"
        pixlui:textAllCaps="true" />

PixlUI also allows you to set a custom typeface/font which you put in your assets folder.

I'm working on a Gradle fork of the PixlUI framework which uses gradle and allows one to specify textAllCaps as well as the typeface from styles rather than requiring them inline as the original project does.

For the latest version of the API the exact opposite seems to be true for me.

When calling the url https://maps.googleapis.com/maps/api/geocode/json?address=<address>&key=<key> I was getting the following error

Once I switched the order to https://maps.googleapis.com/maps/api/geocode/json?key=<key>&address=<address> it worked fine.

Note that the error message received above was the message I got when going directly to the URL in the browser. When I called the API from a software program I received an HTML response with basically the following message:

if you don't want to import the apache commons library try this simple code:

final static int MAX_ELEMENT = 20;

public static void main(final String[] args) {

    final List<String> list = new ArrayList<String>();

    for (int i = 1; i <= 161; i++) {
        list.add(String.valueOf(i));
        System.out.print("," + String.valueOf(i));
    }
    System.out.println("");
    System.out.println("### >>> ");
    final List<List<String>> result = splitList(list, MAX_ELEMENT);

    for (final List<String> entry : result) {
        System.out.println("------------------------");
        for (final String elm : entry) {
            System.out.println(elm);
        }
        System.out.println("------------------------");
    }

}

private static List<List<String>> splitList(final List<String> list, final int maxElement) {

    final List<List<String>> result = new ArrayList<List<String>>();

    final int div = list.size() / maxElement;

    System.out.println(div);

    for (int i = 0; i <= div; i++) {

        final int startIndex = i * maxElement;

        if (startIndex >= list.size()) {
            return result;
        }

        final int endIndex = (i + 1) * maxElement;

        if (endIndex < list.size()) {
            result.add(list.subList(startIndex, endIndex));
        } else {
            result.add(list.subList(startIndex, list.size()));
        }

    }

    return result;
}

If you want to edit that file (or any file in generally), you can't edit it simply writing its name in terminal. You must to use a command to a text editor to do this. For example:

nano ~/.bashrc

or

gedit ~/.bashrc

And in general, for any type of file:

xdg-open ~/.bashrc

Writing only ~/.bashrc in terminal, this will try to execute that file, but .bashrc file is not meant to be an executable file. If you want to execute the code inside of it, you can source it like follow:

source ~/.bashrc

or simple:

. ~/.bashrc 

By default CM10 only allows root access from Apps not ADB. Go to Settings -> Developer options -> Root access, and change option to "Apps and ADB".

You could include the same project in more than one solution, but you're guaranteed to run into problems sometime down the road (relative paths can become invalid when you move directories around for example)

After years of struggling with this, I finally came up with a workable solution, but it requires you to use Subversion for source control (which is not a bad thing)

At the directory level of your solution, add a svn:externals property pointing to the projects you want to include in your solution. Subversion will pull the project from the repository and store it in a subfolder of your solution file. Your solution file can simply use relative paths to refer to your project.

If I find some more time, I'll explain this in detail.

You can use istringstream.

string s = "10";

// create an input stream with your string.
istringstream is(str);

int i;
// use is like an input stream
is >> i;

This would be helpful for someone like me. Create custom dialog style:

<style name="MyDialog" parent="Theme.AppCompat.Light.Dialog">
    <item name="windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowIsFloating">false</item>
</style>

In AndroidManifest.xml file set theme for wanted activity:

<activity
        android:name=".CustomDialog"
        ...
        android:theme="@style/MyDialog"/>

That is all, no need to call methods programaticaly.

The following code will work:

ComboBox1.SelectedIndex.Equals(String.Empty);

I think its not html target properties problem but you unchecked "open nw windows in a new tab instead" option in "tab" tab under firefox "options" menu. check it and try again.

use .NET3.5 it worked for me for similar issue.

Use Perl instead perhaps?

perl -e 'print scalar localtime( time - 86400 ) . "\n";'

Or, use nawk and (ab)use /usr/bin/adb:

nawk 'BEGIN{printf "0t%d=Y\n", srand()-86400}' | adb

Came across this too ... insane!

/usr/bin/truss /usr/bin/date 2>&1 | nawk -F= '/^time\(\)/ {gsub(/ /,"",$2);printf "0t%d=Y\n", $2-86400}' | adb

Well, the <head> tag has nothing to do with the <header> tag. In the head comes all the metadata and stuff, while the header is just a layout component.
And layout comes into body. So I disagree with you.

It cannot be done. It is impossible.

I also had the issue of parsing and using JSON objects in C#. I checked the dynamic type with some libraries, but the issue was always checking if a property exists.

In the end, I stumbled upon this web page, which saved me a lot of time. It automatically creates a strongly typed class based on your JSON data, that you will use with the Newtonsoft library, and it works perfectly. It also works with languages other than C#.

I don't believe AJAX can handle file uploads but this can be achieved with libraries that leverage flash. Another advantage of the flash implementation is the ability to do multiple files at once (like gmail).

SWFUpload is a good start : http://www.swfupload.org/documentation

jQuery and some of the other libraries have plugins that leverage SWFUpload. On my last project we used SWFUpload and Java without a problem.

Also helpful and worth looking into is Apache's FileUpload : http://commons.apache.org/fileupload/index.html

here's an updated version, not using deprecated methods, based upon @danh32's answer:

protected int getScale(Double contentWidth) {
    if(this.getActivity() != null) {
        DisplayMetrics displaymetrics = new DisplayMetrics();
        this.getActivity().getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
        Double val = displaymetrics.widthPixels / contentWidth * 100d;
        return val.intValue();
    } else {
        return 100;
    }
}

to be used alike:

int initialScale = this.getScale(420d);
this.mWebView.setInitialScale(initialScale);

You can't.

So just don't apply styles directly like that, and apply a class "foo", and then define that in your CSS specification:

a.foo { color : orange; }
a.foo:hover { font-weight : bold; }

Installing Visual C++ is a good first step, though I couldn't say for sure whether the 2010 version will work. Anyway give it a try.

Look for vcvarsall.bat in the Visual C++ installation directory (for Visual Studio 2010 it's in ProgramFiles\Microsoft Visual Studio 10.0\VC). Then add that directory to the system path. If you're doing this on the command line, you can try:

path %path%;c:\path\to\vs2010\bin

then try again to run whatever you were trying to run.

For more permanent effect, add it in the computer system path settings.

I think the answer of Curt is correct, however, what if you want to add a class to a div that already has a class declared in the ASP.NET code.

Here is my solution for that, it is a generic method so you can call it directly as this:

Asp Net Div declaration:

<div id="divButtonWrapper" runat="server" class="text-center smallbutton fixPad">

Code to add class:

divButtonWrapper.AddClassToHtmlControl("nameOfYourCssClass")

Generic class:

public static class HtmlGenericControlExtensions
{
    public static void AddClassToHtmlControl(this HtmlGenericControl htmlGenericControl, string className)
    {
        if (string.IsNullOrWhiteSpace(className))
            return;

        htmlGenericControl
            .Attributes.Add("class", string.Join(" ", htmlGenericControl
            .Attributes["class"]
            .Split(' ')
            .Except(new[] { "", className })
            .Concat(new[] { className })
            .ToArray()));
    }
}

The man page has very detailed descriptions of all of the various options (the status bar is highly configurable). Your best bet is to read through man tmux and pay particular attention to those options that begin with status-.

So, for example, status-bg red would set the background colour of the bar.

The three components of the bar, the left and right sections and the window-list in the middle, can all be configured to suit your preferences. status-left and status-right, in addition to having their own variables (like #S to list the session name) can also call custom scripts to display, for example, system information like load average or battery time.

The option to rename windows or panes based on what is currently running in them is automatic-rename. You can set, or disable it globally with:

setw -g automatic-rename [on | off]

The most straightforward way to become comfortable with building your own status bar is to start with a vanilla one and then add changes incrementally, reloading the config as you go.¹

You might also want to have a look around on github or bitbucket for other people's conf files to provide some inspiration. You can see mine here².

¹ You can automate this by including this line in your .tmux.conf:

bind R source-file ~/.tmux.conf \; display-message "Config reloaded..."

You can then test your new functionality with Ctrlb,Shiftr. tmux will print a helpful error message—including a line number of the offending snippet—if you misconfigure an option.

² Note: I call a different status bar depending on whether I am in X or the console - I find this quite useful.

You can serialize simple data to check for equality:

data1 = {firstName: 'John', lastName: 'Smith'};
data2 = {firstName: 'Jane', lastName: 'Smith'};
JSON.stringify(data1) === JSON.stringify(data2)

This will give you something like

'{firstName:"John",lastName:"Smith"}' === '{firstName:"Jane",lastName:"Smith"}'

As a function...

function compare(a, b) {
  return JSON.stringify(a) === JSON.stringify(b);
}
compare(data1, data2);

EDIT

If you're using chai like you say, check out http://chaijs.com/api/bdd/#equal-section

EDIT 2

If you just want to check keys...

function compareKeys(a, b) {
  var aKeys = Object.keys(a).sort();
  var bKeys = Object.keys(b).sort();
  return JSON.stringify(aKeys) === JSON.stringify(bKeys);
}

should do it.

Why don't you just save/serve the CSS file as UTF-8?

nav a:hover:after {
    content: "?";
}

If that's not good enough, and you want to keep it all-ASCII:

nav a:hover:after {
    content: "\2193";
}

The general format for a Unicode character inside a string is \000000 to \FFFFFF – a backslash followed by six hexadecimal digits. You can leave out leading 0 digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.

Relevant part of the CSS2 spec:

Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:

1. with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
2. by providing exactly 6 hexadecimal digits: "\000026B" ("&B")

In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.

If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).

• Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).
  The identifier "te\st" is exactly the same identifier as "test".

Comprehensive list: Unicode Character 'DOWNWARDS ARROW' (U+2193).

I needed this information too and got information with this method,

Launch PowerShell

run the 'import-module servermanager' command ( without quotes )

after that for asp.net 3.5 check run the 'get-windowsfeature web-asp-net' command ( without quotes )

for asp.net 4.5 check run the 'get-windowsfeature Net-Framework-45-Core' command ( without quotes )

Both of the commands will inform you below Install State header.

Detecting version via GUI in server environment and details can be found in this link.

You have a multiple options:

First, you can use kill. But you need the pid of your process, which you can get by using ps, pidof or pgrep.

ps -A  // to get the pid, can be combined with grep
-or-
pidof <name>
-or-
pgrep <name>

kill <pid>

It is possible to kill a process by just knowing the name. Use pkill or killall.

pkill <name>
-or-
killall <name>

All commands send a signal to the process. If the process hung up, it might be neccessary to send a sigkill to the process (this is signal number 9, so the following examples do the same):

pkill -9 <name>
pkill -SIGKILL <name>

You can use this option with kill and killall, too.

yes, static block is used for initialize the code and it will load at the time JVM start for execution.

static block is used in previous versions of java but in latest version it doesn't work.

The solution is to add height:100%; to all the parent elements of your .wrapper-div as well. So:

html{
    height: 100%;
}

body{ 
    margin:0;
    padding:0;
    overflow:hidden;
    height:100%;
}

#container{
    width:1000px;
    margin:0 auto;
    height:100%;
}

Basically, you have three options:

1. Neither specify EXPOSE nor -p
2. Only specify EXPOSE
3. Specify EXPOSE and -p

1) If you specify neither EXPOSE nor -p, the service in the container will only be accessible from inside the container itself.

2) If you EXPOSE a port, the service in the container is not accessible from outside Docker, but from inside other Docker containers. So this is good for inter-container communication.

3) If you EXPOSE and -p a port, the service in the container is accessible from anywhere, even outside Docker.

The reason why both are separated is IMHO because:

• choosing a host port depends on the host and hence does not belong to the Dockerfile (otherwise it would be depending on the host),
• and often it's enough if a service in a container is accessible from other containers.

The documentation explicitly states:

The EXPOSE instruction exposes ports for use within links.

It also points you to how to link containers, which basically is the inter-container communication I talked about.

PS: If you do -p, but do not EXPOSE, Docker does an implicit EXPOSE. This is because if a port is open to the public, it is automatically also open to other Docker containers. Hence -p includes EXPOSE. That's why I didn't list it above as a fourth case.

Assuming you've checked the file is actually present on the server, this could also be caused by your web server restricting which file types are served:

• In Apache this could be done with with the <FilesMatch> directive or a RewriteRule if you're using mod_rewrite.
• In IIS you'd need to look to the Web.config file.

There's a Windows answer, and a Debian answer, so here's a Mac one:

This assumes you're just here looking for a quick way to make a customisable alert sound, and not specifically the piezeoelectric beep you get on Windows:

os.system( "say beep" )

Disclaimer: You can replace os.system with a call to the subprocess module if you're worried about someone hacking on your beep code.

See: How to make the hardware beep sound in Mac OS X 10.6

A simple solution is

UUID.randomUUID().toString().replace("-", "")

(Like the existing solutions, only that it avoids the String#replaceAll call. Regular expression replacement is not required here, so String#replace feels more natural, though technically it still is implemented with regular expressions. Given that the generation of the UUID is more costly than the replacement, there should not be a significant difference in runtime.)

Using the UUID class is probably fast enough for most scenarios, though I would expect that some specialized hand-written variant, which does not need the postprocessing, to be faster. Anyway, the bottleneck of the overall computation will normally be the random number generator. In case of the UUID class, it uses SecureRandom.

Which random number generator to use is also a trade-off that depends on the application. If it is security-sensitive, SecureRandom is, in general, the recommendation. Otherwise, ThreadLocalRandom is an alternative (faster than SecureRandom or the old Random, but not cryptographically secure).

Another thing to check before you start playing with Xcode preferences is:

Select your target and go to Build Settings > Packaging > Wrapper Extension

The value there should be: app

If not double click it and type "app" without the qoutes.

Removes everything between & and ; which all such symbols have. if you juts want to get rid of them.

text.replace(/&.*;/g,'');

FIXED!

I've been wrestling with the same issue, and just had a breakthrough! We've established that if you give the image a background color or image, the png displays properly on top of it. The black border is gone, but now you've got an opaque background, and that pretty much defeats the purpose.

Then I remembered a rgba to ie filter converter I came across. (Thanks be to Michael Bester). So I wondered what would happen if I gave my problem pngs an ie filtered background emulating rgba(255,255,255,0), fully expecting it not to work, but lets try it anyway...

.item img {
    background: transparent;
    -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#00FFFFFF,endColorstr=#00FFFFFF)"; /* IE8 */   
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#00FFFFFF,endColorstr=#00FFFFFF);   /* IE6 & 7 */      
    zoom: 1;

}

Presto! Goodbye black, and hello working alpha channels in ie7 and 8. Fade your pngs in and out, or animate them across the screen - it's all good.

The GUI based approach would be to add an additional module in your project.

1. From the File menu select Project Structure and click on the green plus icon on the top left.
2. The new Module dialog pops
3. From the phone and tablet application group select the "Import JAR or AAR package" option and click next.
4. Follow the steps to create a new module that contains your JAR file.
5. Click on the entry that corresponds to your main project and select the dependencies tab.
6. Add a dependency to the module that you created in step 4.

One final piece of advice. Make sure that the JAR file you include is build with at most JDK 1.7. Many problems relating to error message "com.android.dx.cf.iface.ParseException: bad class file magic (cafebabe) or version (0034.0000)" root straight to this :0.

The code below should be enough to get you started. Tested in Opera, IE and Chrome.

<script>
var l=0;
function f(i){
im = 'i' + l;
d=document.all[im];
d.height=99;
document.all.f1.t1.value=i;
im = 'i' + i;
d=document.all[im];
d.height=1;
l=i;
}
</script>
<center>
<form id='f1'>
<input type=text value=0 id='t1'>
</form>
<script>
for (i=0;i<=50;i++)
 {
 s = "<img src='j.jpg' height=99 width=9 onMouseOver='f(" + i + ")' id='i" + i + "'>";
 document.write(s);
 }
</script>

Using more_itertools.with_iter, it is possible to open, read, close and assign an equivalent output in one line (excluding the import statement):

import more_itertools as mit


output = "".join(line for line in mit.with_iter(open("pagehead.section.htm", "r")))

Although possible, I would look for another approach other than assigning the contents of a file to a variable, i.e. lazy iteration - this can be done using a traditional with block or in the example above by removing join() and iterating output.

There is an implementation in my TypeScript utilities based on JavaScript GUID generators.

Here is the code:

class Guid {_x000D_
  static newGuid() {_x000D_
    return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {_x000D_
      var r = Math.random() * 16 | 0,_x000D_
        v = c == 'x' ? r : (r & 0x3 | 0x8);_x000D_
      return v.toString(16);_x000D_
    });_x000D_
  }_x000D_
}_x000D_
_x000D_
// Example of a bunch of GUIDs_x000D_
for (var i = 0; i < 100; i++) {_x000D_
  var id = Guid.newGuid();_x000D_
  console.log(id);_x000D_
}

Please note the following:

C# GUIDs are guaranteed to be unique. This solution is very likely to be unique. There is a huge gap between "very likely" and "guaranteed" and you don't want to fall through this gap.

JavaScript-generated GUIDs are great to use as a temporary key that you use while waiting for a server to respond, but I wouldn't necessarily trust them as the primary key in a database. If you are going to rely on a JavaScript-generated GUID, I would be tempted to check a register each time a GUID is created to ensure you haven't got a duplicate (an issue that has come up in the Chrome browser in some cases).

This answer is counting that the second parameter is useless when calling removeAttr! (as it was when this answer was posted) Do not use this otherwise!

Can't beat RienNeVaPlus's clean answer, but it does the job as well, it's basically a more compressed way to do the ternary operation:

$('.list-sort')[$('.list-sort').hasAttr('colspan') ? 
    'removeAttr' : 'attr']('colspan', 6);

an extra variable can be used in these cases, when you need to use the reference more than once:

var $listSort = $('.list-sort'); 
$listSort[$listSort.hasAttr('colspan') ? 'removeAttr' : 'attr']('colspan', 6);

System.gc(); 

Runs the garbage collector.

Calling the gc method suggests that the Java Virtual Machine expend effort toward recycling unused objects in order to make the memory they currently occupy available for quick reuse. When control returns from the method call, the Java Virtual Machine has made a best effort to reclaim space from all discarded objects.

Not recommended.

Edit: I wrote the original response in 2009. It's now 2015.

Garbage collectors have gotten steadily better in the ~20 years Java's been around. At this point, if you're manually calling the garbage collector, you may want to consider other approaches:

• If you're forcing GC on a limited number of machines, it may be worth having a load balancer point away from the current machine, waiting for it to finish serving to connected clients, timeout after some period for hanging connections, and then just hard-restart the JVM. This is a terrible solution, but if you're looking at System.gc(), forced-restarts may be a possible stopgap.
• Consider using a different garbage collector. For example, the (new in the last six years) G1 collector is a low-pause model; it uses more CPU overall, but does it's best to never force a hard-stop on execution. Since server CPUs now almost all have multiple cores, this is A Really Good Tradeoff to have available.
• Look at your flags tuning memory use. Especially in newer versions of Java, if you don't have that many long-term running objects, consider bumping up the size of newgen in the heap. newgen (young) is where new objects are allocated. For a webserver, everything created for a request is put here, and if this space is too small, Java will spend extra time upgrading the objects to longer-lived memory, where they're more expensive to kill. (If newgen is slightly too small, you're going to pay for it.) For example, in G1:
  • XX:G1NewSizePercent (defaults to 5; probably doesn't matter.)
  • XX:G1MaxNewSizePercent (defaults to 60; probably raise this.)
• Consider telling the garbage collector you're not okay with a longer pause. This will cause more-frequent GC runs, to allow the system to keep the rest of it's constraints. In G1:
  • XX:MaxGCPauseMillis (defaults to 200.)

I did something similar but I use binding to get the selected item :

<DataGrid Grid.Row="1" AutoGenerateColumns="False" Name="dataGrid"
          IsReadOnly="True" SelectionMode="Single"
          ItemsSource="{Binding ObservableContactList}" 
          SelectedItem="{Binding SelectedContact}">
  <DataGrid.Columns>
    <DataGridTextColumn Binding="{Binding Path=Name}" Header="Name"/>
    <DataGridTextColumn Binding="{Binding Path=FamilyName}" Header="FamilyName"/>
    <DataGridTextColumn Binding="{Binding Path=Age}" Header="Age"/>
    <DataGridTextColumn Binding="{Binding Path=Relation}" Header="Relation"/>
    <DataGridTextColumn Binding="{Binding Path=Phone.Display}" Header="Phone"/>
    <DataGridTextColumn Binding="{Binding Path=Address.Display}" Header="Addr"/>
    <DataGridTextColumn Binding="{Binding Path=Mail}" Header="E-mail"/>
  </DataGrid.Columns>
</DataGrid>

So I can access my SelectedContact.Name in my ViewModel.

You can install multiple Java runtimes under Windows (including Windows 7) as long as each is in their own directory.

For example, if you are running Win 7 64-bit, or Win Server 2008 R2, you may install 32-bit JRE in "C:\Program Files (x86)\Java\jre6" and 64-bit JRE in "C:\Program Files\Java\jre6", and perhaps IBM Java 6 in "C:\Program Files (x86)\IBM\Java60\jre".

The Java Control Panel app theoretically has the ability to manage multiple runtimes: Java tab >> View... button

There are tabs for User and System settings. You can add additional runtimes with Add or Find, but once you have finished adding runtimes and hit OK, you have to hit Apply in the main Java tab frame, which is not as obvious as it could be - otherwise your changes will be lost.

If you have multiple versions installed, only the main version will auto-update. I have not found a solution to this apart from the weak workaround of manually updating whenever I see an auto-update, so I'd love to know if anyone has a fix for that.

Most Java IDEs allow you to select any Java runtime on your machine to build against, but if not using an IDE, you can easily manage this using environment variables in a cmd window. Your PATH and the JAVA_HOME variable determine which runtime is used by tools run from the shell. Set the JAVA_HOME to the jre directory you want and put the bin directory into your path (and remove references to other runtimes) - with IBM you may need to add multiple bin directories. This is pretty much all the set up that the default system Java does. You can also set CLASSPATH, ANT_HOME, MAVEN_HOME, etc. to unique values to match your runtime.

One of the possible solution you might be interested in. Traversing an array of chars from right to left and vise versa in one loop.

public static string WordsToCapitalLetter(string value)
    {
        if (string.IsNullOrWhiteSpace(value))
        {
            throw new ArgumentException("value");
        }

        int inputValueCharLength = value.Length;
        var valueAsCharArray = value.ToCharArray();

        int min = 0;
        int max = inputValueCharLength - 1;

        while (max > min)
        {
            char left = value[min];
            char previousLeft = (min == 0) ? left : value[min - 1];

            char right = value[max];
            char nextRight = (max == inputValueCharLength - 1) ? right : value[max - 1];

            if (char.IsLetter(left) && !char.IsUpper(left) && char.IsWhiteSpace(previousLeft))
            {
                valueAsCharArray[min] = char.ToUpper(left);
            }

            if (char.IsLetter(right) && !char.IsUpper(right) && char.IsWhiteSpace(nextRight))
            {
                valueAsCharArray[max] = char.ToUpper(right);
            }

            min++;
            max--;
        }

        return new string(valueAsCharArray);
    }

Keep in mind that you don't want to zoom in/out UIImage. Instead try to zoom in/out the View which contains the UIImage View Controller.

I have made a solution for this problem. Take a look at my code:

@IBAction func scaleImage(sender: UIPinchGestureRecognizer) {
        self.view.transform = CGAffineTransformScale(self.view.transform, sender.scale, sender.scale)
        sender.scale = 1
    }
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        view.backgroundColor = UIColor.blackColor()
    }

N.B.: Don't forget to hook up the PinchGestureRecognizer.

You shouldn't be importing android.R. That should be automatically generated and recognized. This question contains a lot of helpful tips if you get some error referring to R after removing the import.

Some basic steps after removing the import, if those errors appear:

• Clean your build, then rebuild
• Make sure there are no errors or typos in your XML files
• Make sure your resource names consist of [a-z0-9.]. Capitals or symbols are not allowed for some reason.
• Perform a Gradle sync (via Tools > Android > Sync Project with Gradle Files)

Now, I can't use DateTime?, I am using DBNull.Value for all data types. It works great.

eventCustom.DateTimeEnd = string.IsNullOrWhiteSpace(dateTimeEnd)
  ? DBNull.Value
  : DateTime.Parse(dateTimeEnd);

I have a Windows 2008 server that I'm working on, so my answer is not completely the same as what the OP has on a Windows 2003 server.

Here is what I did (recording this here so I can find it later).

I was having this same issue:

In my Web.config file, I had this section:

<system.web>
    <authentication mode="Windows" />
    <authorization>

Under IIS, all of these seems to be solved under the Authentication icon.

1. Edit Permissions: Make sure your ASP.NET account has permission. Mine was not originally added.

Now go into the features of Authentication:

Enable Anonymous Authentication with the IUSR:

Enable Windows Authentication, then Right-Click to set the Providers.

NTLM needs to be FIRST!

Next, check that under Advanced Settings... the Extended Protection is Accept and Enable Kernel-mode authentication is CHECKED:

Once I did this, I went back to my web application, clicked the Browse link, and logged in without having to provide my credentials again.

I hope this proves beneficial to many of you, and I hope it is useful for me later as well.

This is the sdk path Android Studio installed for me: "C:\Users\<username>\appdata\local\android\sdk"

I'm running windows 8.1.

You can find the path going into Android Studio -> Configure -> SDK Manager -> On the top left it should say SDK Path.

I don't think it's necessary to install the sdk separately, as the default option for Android Studio is to install the latest sdk too.

A library implements functionality for a narrowly-scoped purpose whereas a framework tends to be a collection of libraries providing support for a wider range of features. For example, the library System.Drawing.dll handles drawing functionality, but is only one part of the overall .NET framework.

That part is written to stderr, use 2> to redirect it. For example:

foo > stdout.txt 2> stderr.txt

or if you want in same file:

foo > allout.txt 2>&1

Note: this works in (ba)sh, check your shell for proper syntax

Unfortunately, that's not an Angular2 error, that's an error your browser is running into (i.e. outside of your app).

That CORS header will have to be added to that endpoint on the server before you can make ANY requests.

You're not far; you need to do something like this:

[WebMethod]
public static string GetProducts()
{
  // instantiate a serializer
  JavaScriptSerializer TheSerializer = new JavaScriptSerializer();

  //optional: you can create your own custom converter
  TheSerializer.RegisterConverters(new JavaScriptConverter[] {new MyCustomJson()});

  var products = context.GetProducts().ToList();   

  var TheJson = TheSerializer.Serialize(products);

  return TheJson;
}

You can reduce this code further but I left it like that for clarity. In fact, you could even write this:

return context.GetProducts().ToList();

and this would return a json string. I prefer to be more explicit because I use custom converters. There's also Json.net but the framework's JavaScriptSerializer works just fine out of the box.

This is one "trick" you can do since your out of an async function so can't use await keywork

Do what you want to do with vm.feed inside a setTimeout

vm.feed = getFeed().then(function(data) {return data;});

 setTimeout(() => {
    // do you stuf here
    // after the time you promise will be revolved or rejected
    // if you need some of the values in here immediately out of settimeout
    // might occur an error if promise wore not yet resolved or rejected
    console.log("vm.feed",vm.feed);
 }, 100);

Just in case anyone is in my boat where none of these answers worked exactly, here's what I did.

Perhaps our in house Bitbucket server is set up a little differently than most, but here's the URL that I'd normally go to just to view the files in the master branch:

https://<BITBUCKET_URL>/projects/<PROJECT_GROUP>/repos/<REPO_NAME>/browse

If I select a different branch than master from the drop down menu, I get this:

https://<BITBUCKET_URL>/projects/<PROJECT_GROUP>/repos/<REPO_NAME>/browse?at=refs%2Fheads%2F<BRANCH_NAME>

So I tried doing this and it worked:

https://<BITBUCKET_URL>/projects/<PROJECT_GROUP>/repos/<REPO_NAME>/browse?at=<COMMIT_ID>

Now I can browse the whole repo as it was at the time of that commit.

It's here http://www.android.com/market/featured.html Weirdly, you don't get to that page if you start from the android market and hit "featured". Mary

All the previous answers are correct. Following is the little deep dive into the problem and solution.

The driver constructor in Selenium for example

WebDriver driver = new ChromeDriver();

searches for the driver executable, in this case the Google Chrome driver searches for a Chrome driver executable. In case the service is unable to find the executable, the exception is thrown.

This is where the exception comes from (note the check state method)

 /**
   *
   * @param exeName Name of the executable file to look for in PATH
   * @param exeProperty Name of a system property that specifies the path to the executable file
   * @param exeDocs The link to the driver documentation page
   * @param exeDownload The link to the driver download page
   *
   * @return The driver executable as a {@link File} object
   * @throws IllegalStateException If the executable not found or cannot be executed
   */
  protected static File findExecutable(
      String exeName,
      String exeProperty,
      String exeDocs,
      String exeDownload) {
    String defaultPath = new ExecutableFinder().find(exeName);
    String exePath = System.getProperty(exeProperty, defaultPath);
    checkState(exePath != null,
        "The path to the driver executable must be set by the %s system property;"
            + " for more information, see %s. "
            + "The latest version can be downloaded from %s",
            exeProperty, exeDocs, exeDownload);

    File exe = new File(exePath);
    checkExecutable(exe);
    return exe;
  }

The following is the check state method which throws the exception:

  /**
   * Ensures the truth of an expression involving the state of the calling instance, but not
   * involving any parameters to the calling method.
   *
   * <p>See {@link #checkState(boolean, String, Object...)} for details.
   */
  public static void checkState(
      boolean b,
      @Nullable String errorMessageTemplate,
      @Nullable Object p1,
      @Nullable Object p2,
      @Nullable Object p3) {
    if (!b) {
      throw new IllegalStateException(format(errorMessageTemplate, p1, p2, p3));
    }
  }

SOLUTION: set the system property before creating driver object as follows.

System.setProperty("webdriver.gecko.driver", "path/to/chromedriver.exe");
WebDriver driver = new ChromeDriver();

The following is the code snippet (for Chrome and Firefox) where the driver service searches for the driver executable:

Chrome:

   @Override
    protected File findDefaultExecutable() {
      return findExecutable("chromedriver", CHROME_DRIVER_EXE_PROPERTY,
          "https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver",
          "http://chromedriver.storage.googleapis.com/index.html");
    }

Firefox:

@Override
 protected File findDefaultExecutable() {
      return findExecutable(
        "geckodriver", GECKO_DRIVER_EXE_PROPERTY,
        "https://github.com/mozilla/geckodriver",
        "https://github.com/mozilla/geckodriver/releases");
    }

where CHROME_DRIVER_EXE_PROPERTY = "webdriver.chrome.driver" and GECKO_DRIVER_EXE_PROPERTY = "webdriver.gecko.driver"

Similar is the case for other browsers, and the following is the snapshot of the list of the available browser implementation:

Use the formaction HTML attribute (5th line):

<form action="/action_page.php" method="get">
    First name: <input type="text" name="fname"><br>
    Last name: <input type="text" name="lname"><br>
    <button type="submit">Submit</button><br>
    <button type="submit" formaction="/action_page2.php">Submit to another page</button>
</form>

I ran into the same exact problem around noon today and finally found a solution here --> Trying to resize2fs EB volume fails

I skipped mounting, since the partition was already mounted.

Apparently CentOS 7 uses XFS as the default file system and as a result resize2fs will fail.

I took a look in /etc/fstab, and guess what, XFS was staring me in the face... Hope this helps.

Note that Details is a "View" page under the "Products" folder.

ProductId is the primary key of the table . Here is the line from Index.cshtml

 @Html.ActionLink("Details", "Details","Products" , new  {  id=item.ProductId  },null)

My previous answer was not enough accurate. As truly it was horrible :D But now I can post much more useful and correct answer.

I did some additional tests. You can find it's source by the following link and reCheck it on your environment by your own: https://github.com/ukushu/DataStructuresTestsAndOther.git

Short results:

• Array need to use:

  • So often as possible. It's fast and takes smallest RAM range for same amount information.
  • If you know exact count of cells needed
  • If data saved in array < 85000 b (85000/32 = 2656 elements for integer data)
  • If needed high Random Access speed

• List need to use:

  • If needed to add cells to the end of list (often)
  • If needed to add cells in the beginning/middle of the list (NOT OFTEN)
  • If data saved in array < 85000 b (85000/32 = 2656 elements for integer data)
  • If needed high Random Access speed

• LinkedList need to use:

  • If needed to add cells in the beginning/middle/end of the list (often)
  • If needed only sequential access (forward/backward)
  • If you need to save LARGE items, but items count is low.
  • Better do not use for large amount of items, as it's use additional memory for links.

More details:

Interesting to know:

1. LinkedList<T> internally is not a List in .NET. It's even does not implement IList<T>. And that's why there are absent indexes and methods related to indexes.

2. LinkedList<T> is node-pointer based collection. In .NET it's in doubly linked implementation. This means that prior/next elements have link to current element. And data is fragmented -- different list objects can be located in different places of RAM. Also there will be more memory used for LinkedList<T> than for List<T> or Array.

3. List<T> in .Net is Java's alternative of ArrayList<T>. This means that this is array wrapper. So it's allocated in memory as one contiguous block of data. If allocated data size exceeds 85000 bytes, it will be moved to Large Object Heap. Depending on the size, this can lead to heap fragmentation(a mild form of memory leak). But in the same time if size < 85000 bytes -- this provides a very compact and fast-access representation in memory.

4. Single contiguous block is preferred for random access performance and memory consumption but for collections that need to change size regularly a structure such as an Array generally need to be copied to a new location whereas a linked list only needs to manage the memory for the newly inserted/deleted nodes.

Here's a really simple example that might get you started:

$(document).ready(function() {
    var $dragging = null;

    $(document.body).on("mousemove", function(e) {
        if ($dragging) {
            $dragging.offset({
                top: e.pageY,
                left: e.pageX
            });
        }
    });


    $(document.body).on("mousedown", "div", function (e) {
        $dragging = $(e.target);
    });

    $(document.body).on("mouseup", function (e) {
        $dragging = null;
    });
});

Example: http://jsfiddle.net/Jge9z/

I understand that I shall use the mouse position relative to the container div (in which the div shall be dragged) and that I shall set the divs offset relative to those values.

Not so sure about that. It seems to me that in drag and drop you'd always want to use the offset of the elements relative to the document.

If you mean you want to constrain the dragging to a particular area, that's a more complicated issue (but still doable).

Those answers aren't bad, but they are limited in that they don't actually allow you to enter data. We had a similar problem where we were using barcode readers to enter data into a field, but we wanted to suppress the keyboard.

This is what I put together, it works pretty well:

https://codepen.io/bobjase/pen/QrQQvd/

<!-- must be a select box with no children to suppress the keyboard -->
input: <select id="hiddenField" /> 
<span id="fakecursor" />

<input type="text" readonly="readonly" id="visibleField" />
<div id="cursorMeasuringDiv" />

#hiddenField {
  height:17px; 
  width:1px;
  position:absolute;
  margin-left:3px;
  margin-top:2px;
  border:none;
  border-width:0px 0px 0px 1px;
}

#cursorMeasuringDiv {
  position:absolute;
  visibility:hidden;
  margin:0px;
  padding:0px;
}

#hiddenField:focus {
  border:1px solid gray;  
  border-width:0px 0px 0px 1px;
  outline:none;
  animation-name: cursor;
  animation-duration: 1s;
  animation-iteration-count: infinite;
}

@keyframes cursor {
    from {opacity:0;}
    to {opacity:1;}
}

// whenever the visible field gets focused
$("#visibleField").bind("focus", function(e) {
  // silently shift the focus to the hidden select box
  $("#hiddenField").focus();
  $("#cursorMeasuringDiv").css("font", $("#visibleField").css("font"));
});

// whenever the user types on his keyboard in the select box
// which is natively supported for jumping to an <option>
$("#hiddenField").bind("keypress",function(e) {
  // get the current value of the readonly field
  var currentValue = $("#visibleField").val();

  // and append the key the user pressed into that field
  $("#visibleField").val(currentValue + e.key);
  $("#cursorMeasuringDiv").text(currentValue + e.key);

  // measure the width of the cursor offset
  var offset = 3;
  var textWidth = $("#cursorMeasuringDiv").width();
  $("#hiddenField").css("marginLeft",Math.min(offset+textWidth,$("#visibleField").width()));

});

When you click in the <input> box, it simulates a cursor in that box but really puts the focus on an empty <select> box. Select boxes naturally allow for keypresses to support jumping to an element in the list so it was only a matter of rerouting the keypress to the original input and offsetting the simulated cursor.

This won't work for backspace, delete, etc... but we didn't need those. You could probably use jQuery's trigger to send the keyboard event directly to another input box somewhere but we didn't need to bother with that so I didn't do it.

The problem is with percentage sizing. You are not defining the size of the parent div (the new one), so the browser can not report the size to the Google Maps API. Giving the wrapper div a specific size, or a percentage size if the size of its parent can be determined, will work.

See this explanation from Mike Williams' Google Maps API v2 tutorial:

If you try to use style="width:100%;height:100%" on your map div, you get a map div that has zero height. That's because the div tries to be a percentage of the size of the <body>, but by default the <body> has an indeterminate height.

There are ways to determine the height of the screen and use that number of pixels as the height of the map div, but a simple alternative is to change the <body> so that its height is 100% of the page. We can do this by applying style="height:100%" to both the <body> and the <html>. (We have to do it to both, otherwise the <body> tries to be 100% of the height of the document, and the default for that is an indeterminate height.)

Add the 100% size to html and body in your css

    html, body, #map-canvas {
        margin: 0;
        padding: 0;
        height: 100%;
        width: 100%;
    }

Add it inline to any divs that don't have an id:

<body>
  <div style="height:100%; width: 100%;"> 
    <div id="map-canvas"></div>
  </div>
</body>

You have a file myFile.txt you want to commit.

The right procedure is :

1. Move to the file folder
2. svn up
3. svn commit myFile.txt -m "Insert here a commit message!!!"

Hope this will help someone.

Instead of exceptions, just use:

if (Build.VERSION.SDK_INT >= 11)

and use

@SuppressLint("NewApi")

to suppress the warnings.

One of the simplest way is to use flatten(), like this example :

 import numpy as np

 batch_y =train_output.iloc[sample, :]
 batch_y = np.array(batch_y).flatten()

My array it was like this :

    0
0   6
1   6
2   5
3   4
4   3
.
.
.

After using flatten():

array([6, 6, 5, ..., 5, 3, 6])

It's also the solution of errors of this type :

Cannot feed value of shape (100, 1) for Tensor 'input/Y:0', which has shape '(?,)' 

For something a little more readable, run this command once:

git config --global alias.lg "log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit --date=relative"

so that when you then run:

git lg

you get a nice readout. To show only the last line:

git lg -1

Try using the WHERE clause:

SELECT column1 FROM table WHERE Isnumeric(column1);

VueJS can't pickup your changes to the state if you manipulate arrays like this.

For the record and Google search users, If you are a .NET Core developer, you should set the content-types manually, because their default value is null or empty:

var provider = new FileExtensionContentTypeProvider();
app.UseStaticFiles(new StaticFileOptions
{
    ContentTypeProvider = provider
});

I think you mean to use map instead of filter:

>>> from string import upper
>>> mylis=['this is test', 'another test']
>>> map(upper, mylis)
['THIS IS TEST', 'ANOTHER TEST']

Even simpler, you could use str.upper instead of importing from string (thanks to @alecxe):

>>> map(str.upper, mylis)
['THIS IS TEST', 'ANOTHER TEST']

In Python 2.x, map constructs a new list by applying a given function to every element in a list. filter constructs a new list by restricting to elements that evaluate to True with a given function.

In Python 3.x, map and filter construct iterators instead of lists, so if you are using Python 3.x and require a list the list comprehension approach would be better suited.

Decimal representation of floating point numbers is kind of strange. If you have a number with 15 decimal places and convert that to a double, then print it out with exactly 15 decimal places, you should get the same number. On the other hand, if you print out an arbitrary double with 15 decimal places and the convert it back to a double, you won't necessarily get the same value back—you need 17 decimal places for that. And neither 15 nor 17 decimal places are enough to accurately display the exact decimal equivalent of an arbitrary double. In general, you need over 100 decimal places to do that precisely.

See the Wikipedia page for double-precision and this article on floating-point precision.

Using FilenameUtils in Apache Commons IO :

String name1 = FilenameUtils.getName("/ab/cd/xyz.txt");
String name2 = FilenameUtils.getName("c:\\ab\\cd\\xyz.txt");

You can use the bridgeToObjectiveC() function to make the dictionary a NSDictionary.

Will be like the following:

var dict1 = ["a":"Foo"]
var dict2 = ["b":"Boo"]

var combinedDict = dict1.bridgeToObjectiveC()
var mutiDict1 : NSMutableDictionary! = combinedDict.mutableCopy() as NSMutableDictionary

var combineDict2 = dict2.bridgeToObjectiveC()

var combine = mutiDict1.addEntriesFromDictionary(combineDict2)

Then you can convert the NSDictionary(combine) back or do whatever.

You can use this to fill zeroes in a Mat object already containing data:

image1 = Scalar::all(0);

For eg, if you use it this way:

Mat image,image1;
image = imread("IMG_20160107_185956.jpg", CV_LOAD_IMAGE_COLOR);   // Read the file

if(! image.data )                              // Check for invalid input
{
    cout <<  "Could not open or find the image" << std::endl ;
    return -1;
}
cvtColor(image,image1,CV_BGR2GRAY);
image1 = Scalar::all(0);

It will work fine. But you cannot use this for uninitialised Mat. For that you can go for other options mentioned in above answers, like

Mat drawing = Mat::zeros( image.size(), CV_8UC3 );

You can send it and insert the data to the body:

var xhr = new XMLHttpRequest();
xhr.open("POST", yourUrl, true);
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.send(JSON.stringify({
    value: value
}));

By the way, for get request:

var xhr = new XMLHttpRequest();
// we defined the xhr

xhr.onreadystatechange = function () {
    if (this.readyState != 4) return;

    if (this.status == 200) {
        var data = JSON.parse(this.responseText);

        // we get the returned data
    }

    // end of state change: it can be after some time (async)
};

xhr.open('GET', yourUrl, true);
xhr.send();

You can also register $location on the scope in the controller (to make it accessible from html)

angular.module(...).controller("...", function($location) {
  $scope.$location = $location;
  ...
});

and then go straight for the honey in your html:

<button ng-click="$location.path('#/new-page.html')">New Page<button>

Use typings to access node functions from TypeScript:

typings install env~node --global

If you don't have typings install it:

npm install typings --global

The class attribute can contain multiple styles, so you could specify it as

<tr class="row-even highlight">

and do string manipulation to remove 'highlight' from element.className

element.className=element.className.replace('hightlight','');

Using jQuery would make this simpler as you have the methods

$("#id").addClass("highlight");
$("#id").removeClass("hightlight");

that would enable you to toggle highlighting easily

The [p] is a neat trick to remove the search from showing from ps

@Jeremy If you post the output of ps -ef | grep "port 10", and what you need from the line, it would be more easy to help you getting correct syntax

name() is a "built-in" method of enum. It is final and you cannot change its implementation. It returns the name of enum constant as it is written, e.g. in upper case, without spaces etc.

Compare MOBILE_PHONE_NUMBER and Mobile phone number. Which version is more readable? I believe the second one. This is the difference: name() always returns MOBILE_PHONE_NUMBER, toString() may be overriden to return Mobile phone number.

For scanf, you need to use %hu since you're passing a pointer to an unsigned short. For printf, it's impossible to pass an unsigned short due to default promotions (it will be promoted to int or unsigned int depending on whether int has at least as many value bits as unsigned short or not) so %d or %u is fine. You're free to use %hu if you prefer, though.

Abstraction is hiding the information or providing only necessary details to the client.

e.g Car Brakes- You just know that pressing the pedals will stop the vehicle but you don't need to know how it works internally.

Advantage of Abstraction Tomorrow if brake implementation changes from drum brake to disk brake, as a client, you don't need to change(i.e your code will not change)

Encapsulation is binding the data and behaviors together in a single unit. Also it is a language mechanism for restricting access to some components(this can be achieved by access modifiers like private,protected etc.)

For e.g. Class has attributes(i.e data) and behaviors (i.e methods that operate on that data)

Run this Command

alter user myuser with superuser;

If you want to see the permission to a user run following command

\du

If you simply need a list, you could use:

List<Answer> answers = Arrays.asList(answer1, answer2, answer3);

If you specifically require an ArrayList, you could use:

ArrayList<Answer> answers = new ArrayList(Arrays.asList(answer1, answer2, answer3));

Coming late to the party, but I found this fantastic step-by-step guide on getting control of your SQLExpress instance if you don't have your sa password. I used this process to not only reset my sa password, but I also added my domain account to all the available server roles. I can now create databases, alter logins, do bulk operations, backups/restores, etc using my normal login.

To summarize, you use SQL Server Configuration Manager to put your instance into single-user mode. This elevates you to sysadmin when you connect, allowing you the ability to set everything up.

Edit: I've copied the steps below - kudos to the original author of the link above.

1. Log on to the computer as an Administrator (or Any user with administrator privileges)
2. Open "SQL Server Configuration Manager"
3. Click "SQL Server Services" on the left pane
4. Stop "SQL Server" and "SQL Server Agent" instance on the right pane if it is running
5. Run the SQL Express in single-user mode by right clicking on "SQL Server" instance -> Properties (on the right pane of SQL Server Configuration Manager).
6. Click Advanced Tab, and look for "Startup Parameters". Change the "Startup Parameters" so that the new value will be -m; (without the <>) example: from: -dc:\Program Files\Microsoft SQL.............(til end of string) to: -m;-dc:\Program Files\Microsoft SQL.............(til end of string)
7. Start the SQL Server
8. Open your MS SQL Server Management Studio and log on to the SQL server with "Windows Authentication" as the authentication mode. Since we have the SQL Server running on single user mode, and you are logged on to the computer with Administrator privileges, you will have a "sysadmin" access to the database.
9. Expand the "Security" node on MS SQL Server Management Studio on the left pane
10. Expand the "Logins" node
11. Double-click the 'sa' login
12. Change the password by entering a complex password if "Enforce password policy" is ticked, otherwise, just enter any password.
13. Make sure that "sa" Account is "enabled" by clicking on Status on the left pane. Set the radio box under "Login" to "Enabled"
14. Click "OK"
15. Back on the main window of MS SQL Server Management Studio, verify if SQL Server Authentication is used by right clicking on the top most node in the left pane (usually ".\SQLEXPRESS (SQL Server )") and choosing properties.
16. Click "Security" in the left pane and ensure that "SQL Server and Windows Authentication mode" is the one selected under "Server authentication"
17. Click "OK"
18. Disconnect from MS SQL Server Management Studio
19. Open "Sql Server Configuration Manager" again and stop the SQL Server instance.
20. Right-click on SQL Server instance and click on "Advanced" tab. Again look for "Startup Parameters" and remove the "-m;" that you added earlier.
21. Click "OK" and start the SQL Server Instance again
22. You should now be able to log on as "sa" using the new password that you have set in step 12.

Case 1

INSERT INTO tab_student (name_student, id_teacher_fk)
    VALUES ('dan red', 
           (SELECT id_teacher FROM tab_teacher WHERE name_teacher ='jason bourne')

it is advisable to store your values in lowercase to make retrieval easier and less error prone

Case 2

mysql docs

INSERT INTO tab_teacher (name_teacher) 
    VALUES ('tom stills')
INSERT INTO tab_student (name_student, id_teacher_fk)
    VALUES ('rich man', LAST_INSERT_ID())

<ul>
  <li ng-repeat=interface in interfaces>
       <img src='green-checkmark.png' ng-show="interface=='UP'" />
       <img src='big-black-X.png' ng-show="interface=='DOWN'" />
  </li>
</ul>

In case that you're using a directive like me this is how it works when you need the two data way binding for example after updating an attribute in any model or collection:

angular.module('yourApp').directive('setSurveyInEditionMode', setSurveyInEditionMode)

function setSurveyInEditionMode() {
  return {
    restrict: 'A',
    link: function(scope, element, $attributes) {
      element.on('click', function(event){
        event.stopPropagation();
        // In order to work with stopPropagation and two data way binding
        // if you don't use scope.$apply in my case the model is not updated in the view when I click on the element that has my directive
        scope.$apply(function () {
          scope.mySurvey.inEditionMode = true;
          console.log('inside the directive')
        });
      });
    }
  }
}

Now, you can easily use it in any button, link, div, etc. like so:

<button set-survey-in-edition-mode >Edit survey</button>

Please note: this answer is obsolete, the functionality was removed from iOS simulator.

I have just found that you don't need to copy the mobile application bundle to the iPhone Simulator's folder to start it on the simulator, as described in the forum. That way you need to click on the app to get it started, not confortable when you want to do testing and start the app numerous times.

There are undocumented command line parameters for the iOS Simulator, which can be used for such purposes. The one you are looking for is: -SimulateApplication

An example command line starting up YourFavouriteApp:

/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app/Contents/MacOS/iPhone\ Simulator -SimulateApplication path_to_your_app/YourFavouriteApp.app/YourFavouriteApp

This will start up your application without any installation and works with iOS Simulator 4.2 at least. You cannot reach the home menu, though.

There are other unpublished command line parameters, like switching the SDK. Happy hunting for those...

Sine you've mentioned you're using Eclipse... Eclipse can create the JARs for you, so long as you've run each class that has a main once. Right-click the project and click Export, then select "Runnable JAR file" under the Java folder. Select the class name in the launch configuration, choose a place to save the jar, and make a decision how to handle libraries if necessary. Click finish, wipe hands on pants.

Sure. Here's a completely silly program that demonstrates calling main recursively.

public class main
{
    public static void main(String[] args)
    {
        for (int i = 0; i < args.length; ++i)
        {
            if (args[i] != "")
            {
                args[i] = "";
                System.out.println((args.length - i) + " left");
                main(args);
            }
        }

    }
}

Using environment variable is sometimes more convenient when you do not control the build scripts / process.

For C includes use C_INCLUDE_PATH.

For C++ includes use CPLUS_INCLUDE_PATH.

See this link for other gcc environment variables.

Example usage in MacOS / Linux

# `pip install` will automatically run `gcc` using parameters
# specified in the `asyncpg` package (that I do not control)

C_INCLUDE_PATH=/home/scott/.pyenv/versions/3.7.9/include/python3.7m pip install asyncpg

Example usage in Windows

set C_INCLUDE_PATH="C:\Users\Scott\.pyenv\versions\3.7.9\include\python3.7m"

pip install asyncpg

# clear the environment variable so it doesn't affect other builds
set C_INCLUDE_PATH=

Public Function CheckWholeNumber(Number As Double) As Boolean

        Minutes = Fix(Minutes)
    End If
    If Seconds >= 60 Then
        Seconds = Seconds - 60
        Minutes = Minutes + 1
    End If
    If Minutes >= 60 Then
        Minutes = Minutes - 60
        Hours = Hours + 1
    End If
    If Hours >= 24 Then
        Hours = Hours - 24
        Days = Days + 1
    End If
    Application.Wait _
    ( _

        TimeSerial(Hours + Days * 24, Minutes, 0) + _
        Seconds * TimeSerial(0, 0, 1) _
    )
End Sub

example:

call TimeDelay(1.9,23.9,59.9,59.9999999)

hopy you enjoy.

edit:

here's one without any additional functions, for people who like it being faster

    If Minutes - Fix(Minutes) > 0 Then
        Seconds = Seconds + (Minutes - Fix(Minutes)) * 60
        Minutes = Fix(Minutes)

It appears the proper way to resolve this issue is to run

 pip install --upgrade virtualenv

after you have upgraded python with Homebrew.

This should be a general procedure for any formula that installs something like python, which has it's own package management system. When you install brew install python, you install python and pip and easy_install and virtualenv and so on. So, if those tools can be self-updated, it's best to try to do so before looking to Homebrew as the source of problems.

Is it acceptable & safe to run pip install under sudo?

It's not safe and it's being frowned upon – see What are the risks of running 'sudo pip'? To install Python package in your home directory you don't need root privileges. See description of --user option to pip.

why not use date() just like below,try this

$t = strtotime('20130409163705');
echo date('d/m/y H:i:s',$t);

and will be output

09/04/13 16:37:05

Using this regular expression you can validate different kinds of Date/Time samples, just a little change is needed.

^\d\d\d\d/(0?[1-9]|1[0-2])/(0?[1-9]|[12][0-9]|3[01]) (00|[0-9]|1[0-9]|2[0-3]):([0-9]|[0-5][0-9]):([0-9]|[0-5][0-9])$ -->validate this: 2018/7/12 13:00:00

for your format you cad change it to:

^(0?[1-9]|[12][0-9]|3[01])/(0?[1-9]|1[0-2])/\d\d$ --> validates this: 11/12/98

'Date' is your index so you want to do,

print (df.index.min())
print (df.index.max())

2014-03-13 00:00:00
2014-03-31 00:00:00

Expanding on @stephen's answer, added a few very minor tweaks for display purposes.

function pp($arr){
    $retStr = '<ul>';
    if (is_array($arr)){
        foreach ($arr as $key=>$val){
            if (is_array($val)){
                $retStr .= '<li>' . $key . ' => array(' . pp($val) . '),</li>';
            }else{
                $retStr .= '<li>' . $key . ' => ' . ($val == '' ? '""' : $val) . ',</li>';
            }
        }
    }
    $retStr .= '</ul>';
    return $retStr;
}

Will format any multidimensional array like so:

You can write in this way

<string name="you_me">You &#38; Me<string>

Output: You & Me

Depends, if i remember correctly i think asp.net won't render the html object out when you set visible to false.

If you want to be able to control it from the client side, then you better just include the css value to set it invisible rather than using visible =false.

If your input file is in.txt, you can use freopen to set stdin file as in.txt

freopen("in.txt","r",stdin);

if you want to do the same with your output:

freopen("out.txt","w",stdout);

this will work for std::cin (if using c++), printf, etc...

This will also help you in debugging your code in clion, vscode

My typical expectation is than when "subject" is used a context like this, it means the target of the certificate. If you think of a certificate as a cryptographically secured description of a thing (person, device, communication channel, etc), then the subject is the stuff related to that thing.

It's not the thing itself. For example, no one would say "the subject takes his SmartCard and authenticates his PIN". That would be the "user".

But it usually relates to the various data items related to that that thing. For example:

• Subject DN = Subject Distinguished Name = the unique identifier for what this thing is. Includes information about the thing being certified, including common name, organization, organization unit, country codes, etc.
• Subject Key = part (or all) of the certificate's private/public key pair. If it's coming from the certificate, it's the public key. If it's coming from a key store in a secure location, it's probably the private key. Either part of the key is the cryptographic data used by the thing that received the certificate.
• Subject certificate - the end point for the transaction - this is the thing requesting some secure capability - like integrity checking, authentication, privacy, etc.

Usually, it's used to distinguish between the other players in the PKI world. Namely the "issuer" and the "root". The issuer is the CA that issued the cert (to the subject), and the root is the CA that is end point of all the trust in the heirarchy. The typical relationship is root--->issuer--->subject.

If the numbers aren't supposed to be absurdly huge, maybe use:

new RegExp(
    '^' +                           // No leading content.
    '[-+]?' +                       // Optional sign.
    '(?:[0-9]{0,30}\\.)?' +         // Optionally 0-30 decimal digits of mantissa.
    '[0-9]{1,30}' +                 // 1-30 decimal digits of integer or fraction.
    '(?:[Ee][-+]?[1-2]?[0-9])?' +   // Optional exponent 0-29 for scientific notation.
    '$'                             // No trailing content.
)

This tries to avoid some scenarios, just in case:

• Overflowing any buffers the original string might get passed to.
• Slowness or oddities caused by denormal numbers like 1E-323.
• Passing Infinity when a finite number is expected (try 1E309 or -1E309).

Please try module pexpect. Here is my code:

Here's a Kotlin extension function:

fun EditText.transformIntoDatePicker(context: Context, format: String, maxDate: Date? = null) {
    isFocusableInTouchMode = false
    isClickable = true
    isFocusable = false

    val myCalendar = Calendar.getInstance()
    val datePickerOnDataSetListener =
        DatePickerDialog.OnDateSetListener { _, year, monthOfYear, dayOfMonth ->
            myCalendar.set(Calendar.YEAR, year)
            myCalendar.set(Calendar.MONTH, monthOfYear)
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth)
            val sdf = SimpleDateFormat(format, Locale.UK)
            setText(sdf.format(myCalendar.time))
        }

    setOnClickListener {
        DatePickerDialog(
            context, datePickerOnDataSetListener, myCalendar
                .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
            myCalendar.get(Calendar.DAY_OF_MONTH)
        ).run {
            maxDate?.time?.also { datePicker.maxDate = it }
            show()
        }
    }
}

Usage:

In Activity:

editText.transformIntoDatePicker(this, "MM/dd/yyyy")
editText.transformIntoDatePicker(this, "MM/dd/yyyy", Date())

In Fragments:

editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy")
editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy", Date())

You can also create a database named 'mydatabasename' and then try restoring it again.

Create a new database using MySQL CLI:

mysql -u[username] -p[password]
CREATE DATABASE mydatabasename;

Then try to restore your database:

mysql -u[username] -p[password] mydatabase<mydatabase.sql;

Use django-widget-tweaks, it is easy to use and works pretty well.

Otherwise this can be done using a custom template filter.

Considering you render your form this way :

<form action="/contact/" method="post">
    {{ form.non_field_errors }}
    <div class="fieldWrapper">
        {{ form.subject.errors }}
        <label for="id_subject">Email subject:</label>
        {{ form.subject }}
    </div>
</form>

form.subject is an instance of BoundField which has the as_widget method.

you can create a custom filter "addcss" in "my_app/templatetags/myfilters.py"

from django import template

register = template.Library()

@register.filter(name='addcss')
def addcss(value, arg):
    css_classes = value.field.widget.attrs.get('class', '').split(' ')
    if css_classes and arg not in css_classes:
        css_classes = '%s %s' % (css_classes, arg)
    return value.as_widget(attrs={'class': css_classes})

And then apply your filter:

{% load myfilters %}
<form action="/contact/" method="post">
    {{ form.non_field_errors }}
    <div class="fieldWrapper">
        {{ form.subject.errors }}
        <label for="id_subject">Email subject:</label>
        {{ form.subject|addcss:'MyClass' }}
    </div>
</form>

form.subjects will then be rendered with the "MyClass" css class.

Hope this help.

EDIT 1

• Update filter according to dimyG's answer

• Add django-widget-tweak link

EDIT 2

• Update filter according to Bhyd's comment

The most underrated method is insertAdjacentElement. You can literally add your HTML using one single line.

document.body.insertAdjacentElement('beforeend', html)

Read about it here - https://developer.mozilla.org/en-US/docs/Web/API/Element/insertAdjacentElement

How about std::remove() instead:

#include <algorithm>
...
vec.erase(std::remove(vec.begin(), vec.end(), 8), vec.end());

This combination is also known as the erase-remove idiom.

The only i was able to resolve this issue was to delete the local and git repo and create the same again at both ends. Works fine for now.

The keyboard seems to pop up when the EditText gains focus. To prevent this, set focusable to false:

<EditText
    ...
    android:focusable="false"
    ... />

This behavior can vary on different manufacturers' Android OS flavors, but on the devices I've tested I have found this to to be sufficient. If the keyboard still pops up, using hints instead of text seems to help as well:

myEditText.setText("My text");    // instead of this...
myEditText.setHint("My text");    // try this

Once you've done this, your on click listener should work as desired:

myEditText.setOnClickListener(new OnClickListener() {...});

Don’t add the .table class to your <table> tag. From the Bootstrap docs on tables:

For basic styling—light padding and only horizontal dividers—add the base class .table to any <table>. It may seem super redundant, but given the widespread use of tables for other plugins like calendars and date pickers, we've opted to isolate our custom table styles.

You need to install popperjs along with bootstrap to get rid of this error.Note that if you are using "bootstrap": "^4.4.1", and @popperjs/core v2.x combinations,bootstrap may not support popperjs version. So downgrade your version.

Option 1: npm install popper.js@^1.12.9 --save

and Add following script between jquery and bootstrap scripts.

"node_modules/popper.js/dist/umd/popper.min.js",

Option 2: Add following script tag to index.html

<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js" integrity="sha384-b/U6ypiBEHpOf/4+1nzFpr53nxSS+GLCkfwBdFNTxtclqqenISfwAzpKaMNFNmj4" crossorigin="anonymous"></script

Curly braces. Passing keyword arguments into dict(), though it works beautifully in a lot of scenarios, can only initialize a map if the keys are valid Python identifiers.

This works:

a = {'import': 'trade', 1: 7.8}

a = dict({'import': 'trade', 1: 7.8})

This won't work:

a = dict(import='trade', 1=7.8)

It will result in the following error:

    a = dict(import='trade', 1=7.8)
             ^

This answer only really works if you don't need to do anything other than transferring the inner code (innerHTML) from one to the other:

// Define old parent
var oldParent = document.getElementById('old-parent');

// Define new parent
var newParent = document.getElementById('new-parent');

// Basically takes the inner code of the old, and places it into the new one
newParent.innerHTML = oldParent.innerHTML;

// Delete / Clear the innerHTML / code of the old Parent
oldParent.innerHTML = '';

Hope this helps!

Notepad++ only has column editing. This is not completely the same as multiple cursors.

Sublime Text has a marvelous implementation of this, might be worth checking out...
It's a relatively new editor (2011) that is gaining popularity quite fast: http://www.google.com/trends/explore#q=Notepad%2B%2B%2C%20Sublime%20Text&cmpt=q

Edit: Apparently somewhere around Notepad++ version 6.x multi-cursor editing got added, but there are still a few more advanced features for it in Sublime, like "select next occurrence".

According to the JavaDoc for the .contains(Object obj):

Returns true if this list contains the specified element. More formally, returns true if and only if this list contains at least one element e such that (o==null ? e==null : o.equals(e)).

So if you override your .equals() method for your given object, you should be able to do: if(list1.contains(object2))...

If the elements will be unique (ie. have different attributes) you could override the .equals() and .hashcode() and store everything in HashSets. This will allow you to check if one contains another element in constant time.

=>Create a new table directly with the following query:

CREATE TABLE table_name (Column_1 TEXT,Column_2 TEXT);

=>Now insert the data into table_name from existing_table with the following query:

INSERT INTO table_name (Column_1,Column_2) FROM existing_table;

=>Now drop the existing_table by following query:

DROP TABLE existing_table;

Use this filter mask on email input: emailMask: /[\w.\-@'"!#$%&'*+/=?^_{|}~]/i`

For increased performance you should not evaluate the dataframe using your predicate. You can just use the outcome of your predicate directly as illustrated below:

In [1]: import pandas as pd
        import numpy as np
        df = pd.DataFrame(np.random.randn(20,4),columns=list('ABCD'))


In [2]: df.head()
Out[2]:
          A         B         C         D
0 -2.019868  1.227246 -0.489257  0.149053
1  0.223285 -0.087784 -0.053048 -0.108584
2 -0.140556 -0.299735 -1.765956  0.517803
3 -0.589489  0.400487  0.107856  0.194890
4  1.309088 -0.596996 -0.623519  0.020400

In [3]: %time sum((df['A']>0) & (df['B']>0))
CPU times: user 1.11 ms, sys: 53 µs, total: 1.16 ms
Wall time: 1.12 ms
Out[3]: 4

In [4]: %time len(df[(df['A']>0) & (df['B']>0)])
CPU times: user 1.38 ms, sys: 78 µs, total: 1.46 ms
Wall time: 1.42 ms
Out[4]: 4

Keep in mind that this technique only works for counting the number of rows that comply with your predicate.

loadRequest: is an instance method, not a class method. You should be attempting to call this method with an instance of UIWebview as the receiver, not the class itself.

webviewInstance.loadRequest(NSURLRequest(URL: NSURL(string: "google.ca")!))

However, as @radex correctly points out below, you can also take advantage of currying to call the function like this:

UIWebView.loadRequest(webviewInstance)(NSURLRequest(URL: NSURL(string: "google.ca")!))   

Swift 5

webviewInstance.load(NSURLRequest(url: NSURL(string: "google.ca")! as URL) as URLRequest)

try to use diffrent font-size for li and a

.farParentDiv ul li {
   list-style-type: disc;
   font-size:20px;
}

.farParentDiv ul li a {
   font-size:10px;
}

this saved me from using images

new Date("2011-07-14 11:23:00"); works fine for me.

In Html5, you can now use

<form>
<input type="number" min="1" max="100">
</form>

When loading a resource make sure you notice the difference between:

getClass().getClassLoader().getResource("com/myorg/foo.jpg") //relative path

and

getClass().getResource("/com/myorg/foo.jpg")); //note the slash at the beginning

I guess, this confusion is causing most of problems when loading a resource.

Also, when you're loading an image it's easier to use getResourceAsStream():

BufferedImage image = ImageIO.read(getClass().getResourceAsStream("/com/myorg/foo.jpg"));

When you really have to load a (non-image) file from a JAR archive, you might try this:

File file = null;
String resource = "/com/myorg/foo.xml";
URL res = getClass().getResource(resource);
if (res.getProtocol().equals("jar")) {
    try {
        InputStream input = getClass().getResourceAsStream(resource);
        file = File.createTempFile("tempfile", ".tmp");
        OutputStream out = new FileOutputStream(file);
        int read;
        byte[] bytes = new byte[1024];

        while ((read = input.read(bytes)) != -1) {
            out.write(bytes, 0, read);
        }
        out.close();
        file.deleteOnExit();
    } catch (IOException ex) {
        Exceptions.printStackTrace(ex);
    }
} else {
    //this will probably work in your IDE, but not from a JAR
    file = new File(res.getFile());
}

if (file != null && !file.exists()) {
    throw new RuntimeException("Error: File " + file + " not found!");
}

Floating Point Exception happens because of an unexpected infinity or NaN. You can track that using gdb, which allows you to see what is going on inside your C program while it runs. For more details: https://www.cs.swarthmore.edu/~newhall/unixhelp/howto_gdb.php

In a nutshell, these commands might be useful...

gcc -g myprog.c

gdb a.out

gdb core a.out

ddd a.out

Have the below js inside the iframe and use ajax to submit the form.

$(function(){

   $("form").submit(e){
        e.preventDefault();

       //Use ajax to submit the form
       $.ajax({
          url: this.action,
          data: $(this).serialize(),
          success: function(){
             window.parent.$("#target").load("urlOfThePageToLoad");
          });
       });

   });
