This is what worked for me for extracting TTFs from .dfont and .ttc files from Mac OS X: http://transfonter.org/ttc-unpack

The resulting TTFs work fine in Windows 7.

Ignore the chrome warning. There is no standard MIME type for OTF fonts.

font/opentype may silence the warning, but that doesn't make it the "right" thing to do.

Arguably, you're better off making one up, e.g. with "application/x-opentype" because at least "application" is a registered content type, while "font" is not.

Update: OTF remains a problem, but WOFF grew an IANA MIME type of application/font-woff in January 2013.

Update 2: OTF has grown a MIME type: application/font-sfnt In March 2013. This type also applies to .ttf

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

Decode it.

>>> b'a string'.decode('ascii')
'a string'

To get bytes from string, encode it.

>>> 'a string'.encode('ascii')
b'a string'

You can use this function (I found it here: http://excelribbon.tips.net/T010780_Colors_in_an_IF_Function.html):

Function GetFillColor(Rng As Range) As Long
    GetFillColor = Rng.Interior.ColorIndex
End Function

Here is an explanation, how to create user-defined functions: http://www.wikihow.com/Create-a-User-Defined-Function-in-Microsoft-Excel

In your worksheet, you can use the following: =GetFillColor(B5)

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

You are using encode("utf-8") incorrectly. Python byte strings (str type) have an encoding, Unicode does not. You can convert a Unicode string to a Python byte string using uni.encode(encoding), and you can convert a byte string to a Unicode string using s.decode(encoding) (or equivalently, unicode(s, encoding)).

If fullFilePath and path are currently a str type, you should figure out how they are encoded. For example, if the current encoding is utf-8, you would use:

path = path.decode('utf-8')
fullFilePath = fullFilePath.decode('utf-8')

If this doesn't fix it, the actual issue may be that you are not using a Unicode string in your execute() call, try changing it to the following:

cur.execute(u"update docs set path = :fullFilePath where path = :path", locals())

You can use replace instead of gsub.

"hello _there_".replace(/_(.*?)_/g, "<div>\$1</div>")

<div>
    <p class="some_class">lohrem text (it will be of red color )</p>    
    <div>
        <p class="some_class">lohrem text (it will  NOT be of red color)</p> 
    </div>
    <p class="some_class">lohrem text (it will be  of red color )</p>
</div>

div > p.some_class{
    color:red;
}

All the direct children that are <p> with .some_class would get the style applied to them.

Try

<select id="xxx" name="xxx" class="input-medium" disabled>

Just inserting the line

DateFormatSymbols.getInstance().getMonths()[view.getMonth()] 

will do the trick.

just click file in your android studio then click Sync Project with Gradle Files..

if it won't work, click Build click Clean Project.

it always work for me

Your code was compiled with Java 8.

Either compile your code with an older JDK (compliance level) or run it on a Java 8 JRE.

Hope this helps...

a = ['a1','b2','c3']
b = ['a1','b2','c3']
c = ['b2','a1','c3']

# if you care about order
a == b # True
a == c # False

# if you don't care about order AND duplicates
set(a) == set(b) # True
set(a) == set(c) # True

By casting a, b and c as a set, you remove duplicates and order doesn't count. Comparing sets is also much faster and more efficient than comparing lists.

I just solved this problem very elegantly after a lot of trial and error.

Check out my blog post: http://geon.github.io/programming/2016/02/24/flexbox-full-page-web-app-layout

Basically, to make a flexbox cell scrollable, you have to make all its parents overflow: hidden;, or it will just ignore your overflow settings and make the parent larger instead.

$(document).ready(function() {
  $('#emailid').focusout(function(){
    $('#emailid').filter(function(){
      var email = $('#emailid').val();
      var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
      if ( !emailReg.test( email ) ) {
        alert('Please enter valid email');
      } else {
        alert('Thank you for your valid email');
      }
    });
  });                 
});

The difference from the Java API Specifications is as follows.

For ClassNotFoundException:

Thrown when an application tries to load in a class through its string name using:

• The forName method in class Class.
• The findSystemClass method in class ClassLoader.
• The loadClass method in class ClassLoader.

but no definition for the class with the specified name could be found.

For NoClassDefFoundError:

Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.

The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found.

So, it appears that the NoClassDefFoundError occurs when the source was successfully compiled, but at runtime, the required class files were not found. This may be something that can happen in the distribution or production of JAR files, where not all the required class files were included.

As for ClassNotFoundException, it appears that it may stem from trying to make reflective calls to classes at runtime, but the classes the program is trying to call is does not exist.

The difference between the two is that one is an Error and the other is an Exception. With NoClassDefFoundError is an Error and it arises from the Java Virtual Machine having problems finding a class it expected to find. A program that was expected to work at compile-time can't run because of class files not being found, or is not the same as was produced or encountered at compile-time. This is a pretty critical error, as the program cannot be initiated by the JVM.

On the other hand, the ClassNotFoundException is an Exception, so it is somewhat expected, and is something that is recoverable. Using reflection is can be error-prone (as there is some expectations that things may not go as expected. There is no compile-time check to see that all the required classes exist, so any problems with finding the desired classes will appear at runtime.

Fast and easy with HAVING:

SELECT * FROM tblpm n 
FROM tblpm GROUP BY control_number 
HAVING date_updated=MAX(date_updated);

In the context of HAVING, MAX finds the max of each group. Only the latest entry in each group will satisfy date_updated=max(date_updated). If there's a tie for latest within a group, both will pass the HAVING filter, but GROUP BY means that only one will appear in the returned table.

I'm seeing this issue using Rails 4.0.2 and compass-rails 1.1.3

I got past this error by moving gem 'compass-rails' outside of the :assets group in my Gemfile

It looks something like this:

# stuff
gem 'compass-rails', '~> 1.1.3'
group :assets do
  # more stuff
end

I was also facing this issue when we upgraded from java 8 to java 10. I solved by removing -Djava.endorsed.dirs="C:\Program Files\Apache Software Foundation\Tomcat 8.5\endorsed" from the argument.

I appreciate all correct answers but this is the kotlin answer for the same question

I hope would be helpful to kotlin developers

fun calculateAge(birthDate: Date): Int {
        val now = Date()
        val timeBetween = now.getTime() - birthDate.getTime();
        val yearsBetween = timeBetween / 3.15576e+10;
        return Math.floor(yearsBetween).toInt()
    }

You can read it from the input stream:

public ActionResult ManagePhotos(ManagePhotos model)
{
    if (ModelState.IsValid)
    {
        byte[] image = new byte[model.File.ContentLength];
        model.File.InputStream.Read(image, 0, image.Length); 

        // TODO: Do something with the byte array here
    }
    ...
}

And if you intend to directly save the file to the disk you could use the model.File.SaveAs method. You might find the following blog post useful.

Here's another re + itertools version that should work when searching for either a str or a RegexpObject. I will freely admit that this is likely over-engineered, but for some reason it entertained me.

import itertools
import re

def find_nth(haystack, needle, n = 1):
    """
    Find the starting index of the nth occurrence of ``needle`` in \
    ``haystack``.

    If ``needle`` is a ``str``, this will perform an exact substring
    match; if it is a ``RegexpObject``, this will perform a regex
    search.

    If ``needle`` doesn't appear in ``haystack``, return ``-1``. If
    ``needle`` doesn't appear in ``haystack`` ``n`` times,
    return ``-1``.

    Arguments
    ---------
    * ``needle`` the substring (or a ``RegexpObject``) to find
    * ``haystack`` is a ``str``
    * an ``int`` indicating which occurrence to find; defaults to ``1``

    >>> find_nth("foo", "o", 1)
    1
    >>> find_nth("foo", "o", 2)
    2
    >>> find_nth("foo", "o", 3)
    -1
    >>> find_nth("foo", "b")
    -1
    >>> import re
    >>> either_o = re.compile("[oO]")
    >>> find_nth("foo", either_o, 1)
    1
    >>> find_nth("FOO", either_o, 1)
    1
    """
    if (hasattr(needle, 'finditer')):
        matches = needle.finditer(haystack)
    else:
        matches = re.finditer(re.escape(needle), haystack)
    start_here = itertools.dropwhile(lambda x: x[0] < n, enumerate(matches, 1))
    try:
        return next(start_here)[1].start()
    except StopIteration:
        return -1

Although not as straightforward as isinstance(x, list) one could use as well:

this_is_a_list=[1,2,3]
if type(this_is_a_list) == type([]):
    print("This is a list!")

and I kind of like the simple cleverness of that

Use vim. ^-^ (gVim, to be precise)

You'll have it all (with some plugins).

Btw, snippetsEmu is a nice tool for coding with useful snippets (like in TextMate). You can use (or modify) a pre-made package or make your own.

just tested doing this and it seems to work in firefox & IE

All OS comes with a default version of python and it resides in /usr/bin. All scripts that come with the OS (e.g. yum) point this version of python residing in /usr/bin. When you want to install a new version of python you do not want to break the existing scripts which may not work with new version of python.

The right way of doing this is to install the python as an alternate version.

e.g.
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2 
tar xf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure --prefix=/usr/local/
make && make altinstall

Now by doing this the existing scripts like yum still work with /usr/bin/python. and your default python version would be the one installed in /usr/local/bin. i.e. when you type python you would get 2.7.3

This happens because. $PATH variable has /usr/local/bin before usr/bin.

/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

If python2.7 still does not take effect as the default python version you would need to do

export PATH="/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin"

We passed Json object by HttpPost method, and parse it in dynamic object. it works fine. this is sample code:

webapi:

[HttpPost]
public string DoJson2(dynamic data)
{
   //whole:
   var c = JsonConvert.DeserializeObject<YourObjectTypeHere>(data.ToString()); 

   //or 
   var c1 = JsonConvert.DeserializeObject< ComplexObject1 >(data.c1.ToString());

   var c2 = JsonConvert.DeserializeObject< ComplexObject2 >(data.c2.ToString());

   string appName = data.AppName;
   int appInstanceID = data.AppInstanceID;
   string processGUID = data.ProcessGUID;
   int userID = data.UserID;
   string userName = data.UserName;
   var performer = JsonConvert.DeserializeObject< NextActivityPerformers >(data.NextActivityPerformers.ToString());

   ...
}

The complex object type could be object, array and dictionary.

ajaxPost:
...
Content-Type: application/json,
data: {"AppName":"SamplePrice",
       "AppInstanceID":"100",
       "ProcessGUID":"072af8c3-482a-4b1c??-890b-685ce2fcc75d",
       "UserID":"20",
       "UserName":"Jack",
       "NextActivityPerformers":{
           "39??c71004-d822-4c15-9ff2-94ca1068d745":[{
                 "UserID":10,
                 "UserName":"Smith"
           }]
       }}
...

In addition to the accepted answer, one other check is to make sure that you have the right reference to your entity package in sessionFactory.setPackagesToScan(...) while setting up your session factory.

sh files are unix (linux) shell executables files, they are the equivalent (but much more powerful) of bat files on windows.

So you need to run it from a linux console, just typing its name the same you do with bat files on windows.

Make sure you really need to invert the matrix. This is often unnecessary and can be numerically unstable. When most people ask how to invert a matrix, they really want to know how to solve Ax = b where A is a matrix and x and b are vectors. It's more efficient and more accurate to use code that solves the equation Ax = b for x directly than to calculate A inverse then multiply the inverse by B. Even if you need to solve Ax = b for many b values, it's not a good idea to invert A. If you have to solve the system for multiple b values, save the Cholesky factorization of A, but don't invert it.

See Don't invert that matrix.

As answered misc.imread is deprecated in SciPy 1.0.0, and will be removed in 1.2.0. imageio is one option,it will return object of type :

<class 'imageio.core.util.Image'>

but instead of imageio, use cv2

import cv2
im = cv2.imread('astronaut.png')

im will be of type : <class 'numpy.ndarray'>

As numpy arrays are faster to compute.

I ran into this issue where a client was insisting on this, and they were on a Mac and and iPhone.

I wound up using media queries and a percentage padding for padding-left. Was this a satisfying solution? Not at all, but it let me move on.

way of getting home directory of current user is

String currentUsersHomeDir = System.getProperty("user.home");

and to append path separator

String otherFolder = currentUsersHomeDir + File.separator + "other";

File.separator

The system-dependent default name-separator character, represented as a string for convenience. This string contains a single character, namely separatorChar.

You're looking for the function strcmp, or strncmp from string.h.

Since strings are just arrays, you need to compare each character, so this function will do that for you:

if (strcmp(favoriteDairyProduct, "cheese") == 0)
{
    printf("You like cheese too!");
}
else
{
    printf("I like cheese more.");
}

This Javascript function purports to show the difference between the Blob File API and the Data API to download a JSON file in the client browser:

/**_x000D_
 * Save a text as file using HTML <a> temporary element and Blob_x000D_
 * @author Loreto Parisi_x000D_
 */_x000D_
_x000D_
var saveAsFile = function(fileName, fileContents) {_x000D_
    if (typeof(Blob) != 'undefined') { // Alternative 1: using Blob_x000D_
        var textFileAsBlob = new Blob([fileContents], {type: 'text/plain'});_x000D_
        var downloadLink = document.createElement("a");_x000D_
        downloadLink.download = fileName;_x000D_
        if (window.webkitURL != null) {_x000D_
            downloadLink.href = window.webkitURL.createObjectURL(textFileAsBlob);_x000D_
        } else {_x000D_
            downloadLink.href = window.URL.createObjectURL(textFileAsBlob);_x000D_
            downloadLink.onclick = document.body.removeChild(event.target);_x000D_
            downloadLink.style.display = "none";_x000D_
            document.body.appendChild(downloadLink);_x000D_
        }_x000D_
        downloadLink.click();_x000D_
    } else { // Alternative 2: using Data_x000D_
        var pp = document.createElement('a');_x000D_
        pp.setAttribute('href', 'data:text/plain;charset=utf-8,' +_x000D_
            encodeURIComponent(fileContents));_x000D_
        pp.setAttribute('download', fileName);_x000D_
        pp.onclick = document.body.removeChild(event.target);_x000D_
        pp.click();_x000D_
    }_x000D_
} // saveAsFile_x000D_
_x000D_
/* Example */_x000D_
var jsonObject = {"name": "John", "age": 30, "car": null};_x000D_
saveAsFile('out.json', JSON.stringify(jsonObject, null, 2));

The function is called like saveAsFile('out.json', jsonString);. It will create a ByteStream immediately recognized by the browser that will download the generated file directly using the File API URL.createObjectURL.

In the else, it is possible to see the same result obtained via the href element plus the Data API, but this has several limitations that the Blob API has not.

I might be late. Simply add a new field ID in the table with type AutoNumber. This will generate unique IDs and can utilize in Access too

Add the "extern" keyword to the function definitions in point.h

For me save_queries option was turned off so,

$this->db->save_queries = TRUE; //Turn ON save_queries for temporary use.
$str = $this->db->last_query();
echo $str;

router.navigate vs router.navigateByUrl

router.navigate is just a convenience method that wraps router.navigateByUrl, it boils down to:

navigate(commands: any[], extras) {
    return router.navigateByUrl(router.createUrlTree(commands, extras), extras);
}

As mentioned in other answers router.navigateByUrl will only accept absolute URLs:

// This will work
router.navigateByUrl("http://localhost/team/33/user/11")
// This WON'T work even though relativeTo parameter is in the signature
router.navigateByUrl("../22", {relativeTo: route})

All the relative calculations are done by router.createUrlTree and router.navigate. Array syntax is used to treat every array element as a URL modifying "command". E.g. ".." - go up, "path" - go down, {expand: true} - add query param, etc.. You can use it like this:

// create /team/33/user/11
router.navigate(['/team', 33, 'user', 11]);

// assuming the current url is `/team/33/user/11` and the route points to `user/11`

// navigate to /team/33/user/11/details
router.navigate(['details'], {relativeTo: route});

// navigate to /team/33/user/22
router.navigate(['../22'], {relativeTo: route});

// navigate to /team/44/user/22
router.navigate(['../../team/44/user/22'], {relativeTo: route});

That {relativeTo: route} parameter is important as that's what router will use as the root for relative operations.

Get it through your component's constructor:

  // In my-awesome.component.ts:

  constructor(private route: ActivatedRoute, private router: Router) {}
  
  // Example call
  onNavigateClick() {
    // Navigates to a parent component
    this.router.navigate([..], { relativeTo: this.route })
  }

routerLink directive

Nicest thing about this directive is that it will retrieve the ActivatedRoute for you. Under the hood it's using already familiar:

router.navigateByUrl(router.createUrlTree(commands, { relativeTo: route }), { relativeTo: route });

Following variants will produce identical result:

[routerLink]="['../..']"

// if the string parameter is passed it will be wrapped into an array
routerLink="../.."

Sure, I had a similar issue and a simple

npm uninstall @babel/polyfill --save &&
npm install @babel/polyfill --save

did the trick for me.

However, usage of @babel/polyfill is deprecated (according to this comment) so only try this if you think you have older packages installed or if all else fails.

You can have multiple contexts for single database. It can be useful for example if your database contains multiple database schemas and you want to handle each of them as separate self contained area.

The problem is when you want to use code first to create your database - only single context in your application can do that. The trick for this is usually one additional context containing all your entities which is used only for database creation. Your real application contexts containing only subsets of your entities must have database initializer set to null.

There are other issues you will see when using multiple context types - for example shared entity types and their passing from one context to another, etc. Generally it is possible, it can make your design much cleaner and separate different functional areas but it has its costs in additional complexity.

In JavaScript, the type of key/value store you are attempting to use is an object literal, rather than an array. You are mistakenly creating a composite array object, which happens to have other properties based on the key names you provided, but the array portion contains no elements.

Instead, declare valueToPush as an object and push that onto cookie_value_add:

// Create valueToPush as an object {} rather than an array []
var valueToPush = {};

// Add the properties to your object
// Note, you could also use the valueToPush["productID"] syntax you had
// above, but this is a more object-like syntax
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;

cookie_value_add.push(valueToPush);

// View the structure of cookie_value_add
console.dir(cookie_value_add);

The following code will set the media stream volume to max:

AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,
    audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC),
    AudioManager.FLAG_SHOW_UI);

Try this:

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setTitle("Confirm");
builder.setMessage("Are you sure?");

builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int which) {
        // Do nothing but close the dialog

        dialog.dismiss();
    }
});

builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {

        // Do nothing
        dialog.dismiss();
    }
});

AlertDialog alert = builder.create();
alert.show();

EDIT: You say "I am concatenating simple and short XML file and I do not use serialization, so I need to explicitly escape XML character by hand".

I would strongly advise you not to do it by hand. Use the XML APIs to do it all for you - read in the original files, merge the two into a single document however you need to (you probably want to use XmlDocument.ImportNode), and then write it out again. You don't want to write your own XML parsers/formatters. Serialization is somewhat irrelevant here.

If you can give us a short but complete example of exactly what you're trying to do, we can probably help you to avoid having to worry about escaping in the first place.

Original answer

It's not entirely clear what you mean, but normally XML APIs do this for you. You set the text in a node, and it will automatically escape anything it needs to. For example:

LINQ to XML example:

using System;
using System.Xml.Linq;

class Test
{
    static void Main()
    {
        XElement element = new XElement("tag",
                                        "Brackets & stuff <>");

        Console.WriteLine(element);
    }
}

DOM example:

using System;
using System.Xml;

class Test
{
    static void Main()
    {
        XmlDocument doc = new XmlDocument();
        XmlElement element = doc.CreateElement("tag");
        element.InnerText = "Brackets & stuff <>";
        Console.WriteLine(element.OuterXml);
    }
}

Output from both examples:

<tag>Brackets &amp; stuff &lt;&gt;</tag>

That's assuming you want XML escaping, of course. If you're not, please post more details.

I had this problem with an existing Mongodb setup. I'm still not sure why it happened, but for some reason the Mongod process couldn't find the mongod.config file. Because it could not find the config file it tried to find the DB files in /data/db, a folder that didn't exist. However, the config file was still available so I made sure the process has permissions to the config file and run the mongod process with the --config flag as follows:

mongod --config /etc/mongod.conf

In the config file itself I had this setting:

storage:
  dbPath: /var/lib/mongodb

And this is how the process could find the real DB folder again.

i encountered this error in quite a stupid way

@Autowired
// private Bean bean;

public void myMethod() {
  return;
}

what happened is that I commented a line for some reason and left the annotation which made spring think that the method needs to be autowired

I often using the following is enough

curl -s http://mywebsite.com/myscript.txt | sh

But in a old system( kernel2.4 ), it encounter problems, and do the following can solve it, I tried many others, only the following works

curl -s http://mywebsite.com/myscript.txt -o a.sh && sh a.sh && rm -f a.sh

Examples

$ curl -s someurl | sh
Starting to insert crontab
sh: _name}.sh: command not found
sh: line 208: syntax error near unexpected token `then'
sh: line 208: ` -eq 0 ]]; then'
$

The problem may cause by network slow, or bash version too old that can't handle network slow gracefully

However, the following solves the problem

$ curl -s someurl -o a.sh && sh a.sh && rm -f a.sh
Starting to insert crontab
Insert crontab entry is ok.
Insert crontab is done.
okay

SharePoint uses a lot of different logging mechanisms. Most importantly you can configure the location of the logs through Central Admin. To give you an understanding of the logs involved, here is a quote from http://raiumair.wordpress.com/2007/06/19/quick-a-to-z-of-sharepoint-logs/

All file based logs can be read by text editors and can be parsed by using popular log parsing tools (Log Parser 2.2 from Microsoft or Funnel Web). It will also be a good idea to read the IIS Logs which are generally saved at (System Drive):\WINDOWS\system32\LogFiles

a) Diagnostics Logs

· Event Throttling Logs – These end up going to the Windows Event Log and can be viewed in the Event Viewer. They show Errors and Warnings.

· Trace Logs – These show detailed line by line tracing infomration emitted during a web request or service execution. They end up being stored at a known location on the front-end server. Default Location: (System Drive):\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\LOGS\

b) Audit Logs - They end up in the associated Content Database tables and can be viewed at Site Collection Level as well as Site Level using the web browser. WSS 3.0 and MOSS 2007 use different pages to show Audit Log Reports.

c) Usage Logs – They get stored locally on the front-end servers and get processed both locally and at farm level via SSP (this is based on the setup as I understand the results from the local processing are merged by SSP) and can be viewed at both the Site Level and Site Collection Level. Default Location: (System Drive):\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\Logs

d) Search\Query Logs – These are saved in the associated SSP database but can be viewed at SSP level via the Web Browser and in MOSS at Site Collection Level by going to the settings page.

e) Information Management Logs – Stored in the associated Content Database and can be can be viewed at the Site Collection Level.

f) Content and Structure Logs – This option is only available after one enables the publication feature. This store is saved in the Content Database associated with the Site Collection and can be viewed at Site Collection level by going to the settings page.

If you have readonly attribute, blur by itself would not work. Contraption below should do the job.

$('#myInputID').removeAttr('readonly').trigger('blur').attr('readonly','readonly');

Another truncate with no rounding solution and example.

    Convert 71.950005666 to a single decimal place number (71.9)
    1) 71.950005666 * 10.0 = 719.50005666
    2) Floor(719.50005666) = 719.0
    3) 719.0 / 10.0 = 71.9

    select Floor(71.950005666 * 10.0) / 10.0

On the command prompt, do:

netstat -nb

What you have written in your sql string is a Timestamp not Date. You must convert it to Date or change type of database field to Timestamp for it to be seen correctly.

A view is simply any SELECT query that has been given a name and saved in the database. For this reason, a view is sometimes called a named query or a stored query. To create a view, you use the SQL syntax:

     CREATE OR REPLACE VIEW <view_name> AS
     SELECT <any valid select query>;

In my case the error 1067 was caused with a specific version of Tomcat 7.0.96 32-bit in combination with AdoptOpenJDK. Spent two hours on it, un-installing, re-installing and trying different Java settings but Tomcat would not start. See... ASF Bugzilla – Bug 63625 seems to point at the issue though they refer to seeing a different error.

I tried 7.0.99 32-bit and it started straight away with the same AdoptOpenJDK 32-bit binary install.

@Warren and @DCookie have covered the solution, one thing to emphasise is the use of tnsping. You can use this to prove your TNSNames is correct before attempting to connect.

Once you have set up tnsnames correctly you could use ODBC or try TOra which will use your native oracle connection. TOra or something similar (TOAD, SQL*Plus etc) will prove invaluable in debugging and improving your SQL.

Last but not least when you eventually connect with ASP.net remember that you can use the Oracle data connection libraries. See Oracle.com for a host of resources.

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

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

There seems to be some interest in Gavin's answer for which cortijon proposed a javascript version in the comments and iMalc provided a version with slightly fewer computations. Some have pointed out shortcomings with various code proposals and others have commented on the efficiency of some code proposals.

The algorithm provided by iMalc via Gavin's answer is the one that I am currently using in a javascript project and I just wanted to provide a cleaned up version here if it may help anyone.

// Some variables for reuse, others may do this differently
var p0x, p1x, p2x, p3x, ix,
    p0y, p1y, p2y, p3y, iy,
    collisionDetected;

// do stuff, call other functions, set endpoints...

// note: for my purpose I use |t| < |d| as opposed to
// |t| <= |d| which is equivalent to 0 <= t < 1 rather than
// 0 <= t <= 1 as in Gavin's answer - results may vary

var lineSegmentIntersection = function(){
    var d, dx1, dx2, dx3, dy1, dy2, dy3, s, t;

    dx1 = p1x - p0x;      dy1 = p1y - p0y;
    dx2 = p3x - p2x;      dy2 = p3y - p2y;
    dx3 = p0x - p2x;      dy3 = p0y - p2y;

    collisionDetected = 0;

    d = dx1 * dy2 - dx2 * dy1;

    if(d !== 0){
        s = dx1 * dy3 - dx3 * dy1;
        if((s <= 0 && d < 0 && s >= d) || (s >= 0 && d > 0 && s <= d)){
            t = dx2 * dy3 - dx3 * dy2;
            if((t <= 0 && d < 0 && t > d) || (t >= 0 && d > 0 && t < d)){
                t = t / d;
                collisionDetected = 1;
                ix = p0x + t * dx1;
                iy = p0y + t * dy1;
            }
        }
    }
};

All the solutions given in this thread don't mention an existing - and native - way to solve this problem without reordering DOM and/or using event preventing tricks. But there's a good reason: this way is proprietary - and available on MS web platform only. Quoting MSDN:

-ms-scroll-chaining property - specifies the scrolling behavior that occurs when a user hits the scroll limit during a manipulation. Property values:

chained - Initial value. The nearest scrollable parent element begins scrolling when the user hits a scroll limit during a manipulation. No bounce effect is shown.

none - A bounce effect is shown when the user hits a scroll limit during a manipulation.

Granted, this property is supported on IE10+/Edge only. Still, here's a telling quote:

To give you a sense of how popular preventing scroll chaining may be, according to my quick http-archive search "-ms-scroll-chaining: none" is used in 0.4% of top 300K pages despite being limited in functionality and only supported on IE/Edge.

And now good news, everyone! Starting from Chrome 63, we finally have a native cure for Blink-based platforms too - and that's both Chrome (obviously) and Android WebView (soon).

Quoting the introducing article:

The overscroll-behavior property is a new CSS feature that controls the behavior of what happens when you over-scroll a container (including the page itself). You can use it to cancel scroll chaining, disable/customize the pull-to-refresh action, disable rubberbanding effects on iOS (when Safari implements overscroll-behavior), and more.[...]

The property takes three possible values:

auto - Default. Scrolls that originate on the element may propagate to ancestor elements.

contain - prevents scroll chaining. Scrolls do not propagate to ancestors but local effects within the node are shown. For example, the overscroll glow effect on Android or the rubberbanding effect on iOS which notifies the user when they've hit a scroll boundary. Note: using overscroll-behavior: contain on the html element prevents overscroll navigation actions.

none - same as contain but it also prevents overscroll effects within the node itself (e.g. Android overscroll glow or iOS rubberbanding).

[...] The best part is that using overscroll-behavior does not adversely affect page performance like the hacks mentioned in the intro!

Here's this feature in action. And here's corresponding CSS Module document.

UPDATE: Firefox, since version 59, has joined the club, and MS Edge is expected to implement this feature in version 18. Here's the corresponding caniusage.

Ubuntu 17.10 default doesn't have the ~/.vimrc file, we need create it and put the setting colorscheme color_scheme_name in it.

By the way, colorscheme desert is good scheme to choose.

I solved this error "Compilation failed to see the compiler error output for details"

Great work from @Avanka!

I solved this like this:

    <section className="container-fluid">
            <div className="row justify-content-center">

                <article className="d-flex flex-column justify-content-center align-items-center vh-100">
                        <!-- content -->
                </article>

            </div>
    </section>

Use forward slashes to specify the UNC Path:

open('//HOST/share/path/to/file')

(if your Python client code is also running under Windows)

If Multiset extends from the Array class

x = [1, 1, 2, 4, 7]
y = [1, 2, 2, 2]
z = [1, 1, 3, 7]

UNION

x.union(y)           # => [1, 2, 4, 7]      (ONLY IN RUBY 2.6)
x.union(y, z)        # => [1, 2, 4, 7, 3]   (ONLY IN RUBY 2.6)
x | y                # => [1, 2, 4, 7]

DIFFERENCE

x.difference(y)      # => [4, 7] (ONLY IN RUBY 2.6)
x.difference(y, z)   # => [4] (ONLY IN RUBY 2.6)
x - y                # => [4, 7]

INTERSECTION

x & y                # => [1, 2]

Here's a somewhat cleaner way of implementing this. This makes the following changes:

1. The code is DRYed up a bit to remove redundant and repeated code and strings.
2. The code is made more generic/reusable.
3. We make the cache into an object so it has a self-contained interface and there are fewer globals.
4. We compare .src attributes instead of DOM elements to make it work properly.

Code:

function imageCache(base, firstNum, lastNum) {
    this.cache = [];
    var img;
    for (var i = firstNum; i <= lastnum; i++) {
        img = new Image();
        img.src = base + i + ".jpg";
        this.cache.push(img);
    }
}

imageCache.prototype.nextImage(id) {
    var element = document.getElementById(id);
    var targetSrc = element.src;
    var cache = this.cache;
    for (var i = 0; i < cache.length; i++) {
        if (cache[i].src) === targetSrc) {
            i++;
            if (i >= cache.length) {
                i = 0;
            }
            element.src = cache[i].src;
            return;
        }
    }
}

// sample usage

var myCache = new imageCache('images/img/Splash_image', 1, 6);
myCache.nextImage("foo");

Some advantages of this more object oriented and DRYed approach:

1. You can add more images by just creating the images in the numeric sequences and changing one numeric value in the constructor rather than copying lots more lines of array declarations.
2. You can use this more than one place in your app by just creating more than one imageCache object.
3. You can change the base URL by changing one string rather than N strings.
4. The code size is smaller (because of the removal of repeated code).
5. The cache object could easily be extended to offer more capabilities such as first, last, skip, etc...
6. You could add centralize error handling in one place so if one image doesn't exist and doesn't load successfully, it's automatically removed from the cache.
7. You can reuse this in other web pages you develop by only change the arguments to the constructor and not actually changing the implementation code.

P.S. If you don't know what DRY stands for, it's "Don't Repeat Yourself" and basically means that you should never have many copies of similar looking code. Anytime you have that, it should be reduced somehow to a loop or function or something that removes the need for lots of similarly looking copies of code. The end result will be smaller, usually easier to maintain and often more reusable.

Tip #2

Can't you use the classical 2> redirection operator.

(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) 2> $NULL
if(!$?){
   'foo'
}

I don't like errors so I avoid them at all costs.

You can use df.plot.scatter, and pass an array to c= argument defining the color of each point:

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), index = pd.date_range('2010-01-01', freq = 'M', periods = 10), columns = ('one', 'two', 'three'))
df['key1'] = (4,4,4,6,6,6,8,8,8,8)
colors = np.where(df["key1"]==4,'r','-')
colors[df["key1"]==6] = 'g'
colors[df["key1"]==8] = 'b'
print(colors)
df.plot.scatter(x="one",y="two",c=colors)
plt.show()

Just as an extra to anyone using the above answers that implement:

ObjectType instance = (ObjectType)Activator.CreateInstance(objectType);

Be careful - if your Constructor isn't "Public" then you will get the following error:

"System.MissingMethodException: 'No parameterless constructor defined for this object."

Your class can be Internal/Friend, or whatever you need but the constructor must be public.

Corner case: if you are using m2Eclipse, it automatically puts in excludes on your resources folders. Then when you try to run tests inside eclipse, the subsequent absence of persistence.xml will produce this error.

When Bootstrap Select initializes, it'll build a set of custom divs that run alongside the original <select> element and will typically synchronize state between the two input mechanisms.

Which is to say that one way to handle events on bootstrap select is to listen for events on the original select that it modifies, regardless of who updated it.

Solution 1 - Native Events

Just listen for a change event and get the selected value using javascript or jQuery like this:

$('select').on('change', function(e){

Solution 2 - Bootstrap Select Custom Events

As this answer alludes, Bootstrap Select has their own set of custom events, including changed.bs.select which:

fires after the select's value has been changed. It passes through event, clickedIndex, newValue, oldValue.

And you can use that like this:

$("select").on("changed.bs.select", 
      function(e, clickedIndex, newValue, oldValue) {
    console.log(this.value, clickedIndex, newValue, oldValue)
});

Demo in Stack Snippets:

$(function() {_x000D_
_x000D_
  $("select").on("changed.bs.select", _x000D_
        function(e, clickedIndex, newValue, oldValue) {_x000D_
      console.log(this.value, clickedIndex, newValue, oldValue)_x000D_
  });_x000D_
_x000D_
});

Browser caching strategies can be controlled by HTTP headers. Remember that they are just a hint, really. Since browsers are terribly inconsistent in this (and any other) field, you'll need several headers to get the desired effect on a range of browsers.

header ("Pragma-directive: no-cache");
header ("Cache-directive: no-cache");
header ("Cache-control: no-cache");
header ("Pragma: no-cache");
header ("Expires: 0");

Buttons can be added to frozen rows as images. Assigning a function within the attached script to the button makes it possible to run the function. The comment which says you can not is of course a very old comment, possibly things have changed now.

I can see that this only for actually turning the dialogs back on. But if you are a web dev and you would like to see a way to possibly have some form of notification when these are off...in the case that you are using native alerts/confirms for validation or whatever. Check this solution to detect and notify the user https://stackoverflow.com/a/23697435/1248536

Use .val() instead of .innerHTML for getting value of selected option

Use .text() for getting text of selected option

Thanks for correcting :)

A Ternary is not a good solution for what you want. It will not be readable in your code, and there are much better solutions available.

Why not use an array lookup "map" or "dictionary", like so:

$vocations = array(
    1 => "Sorcerer",
    2 => "Druid",
    3 => "Paladin",
    ...
);

echo $vocations[$result->vocation];

A ternary for this application would end up looking like this:

echo($result->group_id == 1 ? "Player" : ($result->group_id == 2 ? "Gamemaster" : ($result->group_id == 3 ? "God" : "unknown")));

Why is this bad? Because - as a single long line, you would get no valid debugging information if something were to go wrong here, the length makes it difficult to read, plus the nesting of the multiple ternaries just feels odd.

A Standard Ternary is simple, easy to read, and would look like this:

$value = ($condition) ? 'Truthy Value' : 'Falsey Value';

or

echo ($some_condition) ? 'The condition is true!' : 'The condition is false.';

A ternary is really just a convenient / shorter way to write a simple if else statement. The above sample ternary is the same as:

if ($some_condition) {
    echo 'The condition is true!';
} else {
    echo 'The condition is false!';
}

However, a ternary for a complex logic quickly becomes unreadable, and is no longer worth the brevity.

echo($result->group_id == 1 ? "Player" : ($result->group_id == 2 ? "Gamemaster" : ($result->group_id == 3 ? "God" : "unknown")));

Even with some attentive formatting to spread it over multiple lines, it's not very clear:

echo($result->group_id == 1 
    ? "Player" 
    : ($result->group_id == 2 
        ? "Gamemaster" 
        : ($result->group_id == 3 
            ? "God" 
            : "unknown")));

I haven't used it yet but I would take a look at http://www.zoneminder.com/ The documentation explains you can install it on a modest machine with linux and use IP cameras for remote recording.

I think the best way to convert is:

static java.sql.Timestamp SQLDateTime(Long utilDate) {
    return new java.sql.Timestamp(utilDate);
}

Date date = new Date();
java.sql.Timestamp dt = SQLDateTime(date.getTime());

If you want to insert the dt variable into an SQL table you can do:

insert into table (expireAt) values ('"+dt+"');

The best we could come up with is this:

^\\$?(([1-9](\\d*|\\d{0,2}(,\\d{3})*))|0)(\\.\\d{1,2})?$

I realize it might seem too much, but as far as I can test it matches anything that a human eye would accept as valid currency value and weeds out everything else.

It matches these:

1 => true
1.00 => true
$1 => true
$1000 => true
0.1 => true
1,000.00 => true
$1,000,000 => true
5678 => true

And weeds out these:

1.001 => false
02.0 => false
22,42 => false
001 => false
192.168.1.2 => false
, => false
.55 => false
2000,000 => false

The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

ob_start(); 

should be added in the line 1 itself. like in below example

<?php
ob_start(); // needs to be added here
?>
<!DOCTYPE html>
<html lang="en">
// your code goes here
</html>
<?php
if(isset($_POST['submit']))
{ 
//code to save data in db goes here
}
header('location:index.php?msg=sav'); 
?>

adding it below html also doesnt work. like below

<!DOCTYPE html>
<html lang="en">
// your code goes here
</html>
<?php
ob_start(); // it doesnt work even if you add here
if(isset($_POST['submit']))
{ 
//code to save data in db goes here
}
header('location:index.php?msg=sav'); 
?>

You can use this function if you want to add the data into database, with a button. I hope it will help.

// dgvBill is name of DataGridView

string StrQuery;
try
{
    using (SqlConnection conn = new SqlConnection(ConnectingString))
    {
        using (SqlCommand comm = new SqlCommand())
        {
            comm.Connection = conn;
            conn.Open();
            for (int i = 0; i < dgvBill.Rows.Count; i++) 
            {
                StrQuery = @"INSERT INTO tblBillDetails (IdBill, productID, quantity, price,  total) VALUES ('" + IdBillVar+ "','" + dgvBill.Rows[i].Cells[0].Value + "', '" + dgvBill.Rows[i].Cells[4].Value + "', '" + dgvBill.Rows[i].Cells[3].Value + "', '" + dgvBill.Rows[i].Cells[2].Value + "');";
                comm.CommandText = StrQuery;
                comm.ExecuteNonQuery();         
             }
         }
     }
 }
 catch (Exception err)
 {
     MessageBox.Show(err.Message  , "Error !");

There are reserved characters, that have a reserved meanings, those are delimiters — :/?#[]@ — and subdelimiters — !$&'()*+,;=

There is also a set of characters called unreserved characters — alphanumerics and -._~ — which are not to be encoded.

That means, that anything that doesn't belong to unreserved characters set is supposed to be %-encoded, when they do not have special meaning (e.g. when passed as a part of GET parameter).

See also RFC3986: Uniform Resource Identifier (URI): Generic Syntax

Building upon the type-hints answer (https://stackoverflow.com/a/9195565/2418922), which provides a better structured way to document types of parameters, there exist also a structured manner to document both type and descriptions of parameters:

def copy_net(
    infile: (str, 'The name of the file to send'),
    host: (str, 'The host to send the file to'),
    port: (int, 'The port to connect to')):

    pass

Just to mention, you can also use the default a theme like android.R.style.Theme_DeviceDefault_Light_Dialog instead.

new DatePickerDialog(MainActivity.this, android.R.style.Theme_DeviceDefault_Light_Dialog, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    //DO SOMETHING
    }
}, 2015, 02, 26).show();

If you're feeling adventurous, take a look at JScience. It has a Rational class that represents fractions.

If you've not pushed either commit to your remote repository, you could use interactive rebasing to 'reorder' your commits and stash the (new) most recent commit's changes only.

Assuming you have the tip of your current branch (commit 111 in your example) checked out, execute the following:

git rebase -i HEAD~2

This will open your default editor, listing most recent 2 commits and provide you with some instructions. Be very cautious as to what you do here, as you are going to effectively 'rewrite' the history of your repository, and can potentially lose work if you aren't careful (make a backup of the whole repository first if necessary). I've estimated commit hashes/titles below for example

pick 222 commit to be stashed
pick 111 commit to be pushed to remote

# Rebase 111..222 onto 333
#
# Commands:
#  p, pick = use commit
#  r, reword = use commit, but edit the commit message
#  e, edit = use commit, but stop for amending
#  s, squash = use commit, but meld into previous commit
#  f, fixup = like "squash", but discard this commit's log message
#  x, exec = run command (the rest of the line) using shell
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.
#
# Note that empty commits are commented out

Reorder the two commits (they are listed oldest => newest) like this:

pick 111 commit to be pushed to remote
pick 222 commit to be stashed

Save and exit, at which point git will do some processing to rewrite the two commits you have changed. Assuming no issues, you should have reversed the order of your two changesets. This can be confirmed with git log --oneline -5 which will output newest-first.

At this point, you can simply do a soft-reset on the most recent commit, and stash your working changes:

git reset --soft HEAD~1
git stash

It's important to mention that this option is only really viable if you have not previously pushed any of these changes to your remote, otherwise it can cause issues for everyone using the repository.

While templates are probably best for the case you describe, if you have or want your data and/or arguments in iterable/array form, you can use String.raw.

String.raw({
  raw: ["I'm ", " years old!"]
}, 3);

With the data as an array, one can use the spread operator:

const args = [3, 'yesterday'];
String.raw({
  raw: ["I'm ", " years old as of ", ""]
}, ...args);

Here's what I think is safest and simplest. There is nothing here not stated above. I just want to see an answer that shows a safe step-by-step procedure. You start one folder up from the repository (repo) you want to make bare. I've adopted the convention implied above that bare repository folders have a .git extension.

(1) Backup, just in case.
    (a) > mkdir backup
    (b) > cd backup
    (c) > git clone ../repo
(2) Make it bare, then move it
    (a) > cd ../repo
    (b) > git config --bool core.bare true
    (c) > mv .git ../repo.git
(3) Confirm the bare repository works (optional, since we have a backup)
    (a) > cd ..
    (b) > mkdir test
    (c) > cd test
    (d) > git clone ../repo.git
(4) Clean up
    (a) > rm -Rf repo
    (b) (optional) > rm -Rf backup/repo
    (c) (optional) > rm -Rf test/repo

The working directory is a operating system feature (set when the process starts). Why don't you just pass your own System property (-Dsomeprop=/my/path) and use that in your code as the parent of your File:

File f = new File ( System.getProperty("someprop"), myFilename)

Try adding $(document).ready(function(){ to the beginning of your script, and then });. Also, does the div have the id in it properly, i.e., as an id, not a class, etc.?

OneToOneField: if second table is related with

table2_col1 = models.OneToOneField(table1,on_delete=models.CASCADE, related_name='table1_id')

table2 will contains only one record corresponding to table1's pk value, i.e table2_col1 will have unique value equal to pk of table

table2_col1 == models.ForeignKey(table1, on_delete=models.CASCADE, related_name='table1_id')

table2 may contains more than one record corresponding to table1's pk value.

A "program" can be as simple as a "set of instructions" to implement a logic.

It can be part of an "application", "component", "service" or another "program".

Application is a possibly a collection of coordinating program instances to solve a user's purpose.

Use the oncontextmenu event.

Here's an example:

<div oncontextmenu="javascript:alert('success!');return false;">
    Lorem Ipsum
</div>

And using event listeners (credit to rampion from a comment in 2011):

el.addEventListener('contextmenu', function(ev) {
    ev.preventDefault();
    alert('success!');
    return false;
}, false);

Don't forget to return false, otherwise the standard context menu will still pop up.

If you are going to use a function you've written rather than javascript:alert("Success!"), remember to return false in BOTH the function AND the oncontextmenu attribute.

The important thing of table-layout: fixed is that the column widths are determined by the first row of the table.

So

if your table structure is as follow (standard table structure)

<table>
  <thead>
      <tr>
          <th> First column </th>
          <th> Second column </th>
          <th> Third column </th>        
      </tr>
  </thead>

   <tbody>
      <tr>
          <td> First column </td>
          <td> Second column </td>
          <td> Third column </td>        
      </tr>
  </tbody>

if you would like to give a width to second column then

<style> 
    table{
        table-layout:fixed;
        width: 100%;
    }

    table tr th:nth-child(2){
       width: 60%;
     }

</style>

Please look that we style the th not the td.

There are several issues here.

1. You can't assign DataContext as DataContext="{Binding Employee}" because it's a complex object which can't be assigned as string. So you have to use <Window.DataContext></Window.DataContext> syntax.
2. You assign the class that represents the data context object to the view, not an individual property so {Binding Employee} is invalid here, you just have to specify an object.
3. Now when you assign data context using valid syntax like below

   <Window.DataContext>
      <local:Employee/>
   </Window.DataContext>

know that you are creating a new instance of the Employee class and assigning it as the data context object. You may well have nothing in default constructor so nothing will show up. But then how do you manage it in code behind file? You have typecast the DataContext.

    private void my_button_Click(object sender, RoutedEventArgs e)
    {
        Employee e = (Employee) DataContext;
    }

4. A second way is to assign the data context in the code behind file itself. The advantage then is your code behind file already knows it and can work with it.

   public partial class MainWindow : Window
   {
      Employee employee = new Employee();
   
      public MainWindow()
      {
          InitializeComponent();
   
          DataContext = employee;
      }
   }
   

If you need Unicode support in the lower case function see this question: Light C Unicode Library

See section 5.1:

http://docs.python.org/library/stdtypes.html

Any object can be tested for truth value, for use in an if or while condition or as operand of the Boolean operations below. The following values are considered false:

None

False

zero of any numeric type, for example, 0, 0L, 0.0, 0j.

any empty sequence, for example, '', (), [].

any empty mapping, for example, {}.

instances of user-defined classes, if the class defines a __nonzero__() or __len__() method, when that method returns the integer zero or bool value False. [1]

All other values are considered true — so objects of many types are always true.

Operations and built-in functions that have a Boolean result always return 0 or False for false and 1 or True for true, unless otherwise stated. (Important exception: the Boolean operations or and and always return one of their operands.)

I'm using the resposive table code from http://getbootstrap.com/css/#tables-responsive

ie:

<div class="table-responsive">
<table class="table">
...
</table>
</div>

1. First solution

   Avoid System.IO.File.Move solutions posted here (marked answer included). It fails over networks. However, copy/delete pattern works locally and over networks. Follow one of the move solutions, but replace it with Copy instead. Then use File.Delete to delete the original file.

   You can create a Rename method to simplify it.

2. Ease of use

   Use the VB assembly in C#. Add reference to Microsoft.VisualBasic

   Then to rename the file:

   Microsoft.VisualBasic.FileIO.FileSystem.RenameFile(myfile, newName);

   Both are strings. Note that myfile has the full path. newName does not. For example:

   a = "C:\whatever\a.txt";
   b = "b.txt";
   Microsoft.VisualBasic.FileIO.FileSystem.RenameFile(a, b);
   

   The C:\whatever\ folder will now contain b.txt.

I realize this has been well answered but here's a comparison between "$@" $@ "$*" and $*

Contents of test script:

# cat ./test.sh

echo "================================="

echo "Quoted DOLLAR-AT"
for ARG in "$@"; do
    echo $ARG

echo "================================="

echo "NOT Quoted DOLLAR-AT"
for ARG in $@; do
    echo $ARG
done

echo "================================="

echo "Quoted DOLLAR-STAR"
for ARG in "$*"; do
    echo $ARG
done

echo "================================="

echo "NOT Quoted DOLLAR-STAR"
for ARG in $*; do
    echo $ARG
done

echo "================================="

Now, run the test script with various arguments:

# ./test.sh  "arg with space one" "arg2" arg3
=================================
Quoted DOLLAR-AT
arg with space one

=================================
NOT Quoted DOLLAR-AT

The length of an array is immutable in java. This means you can't change the size of an array once you have created it. If you initialised it with 2 elements, its length is 2. You can however use a different collection.

List<Integer> myList = new ArrayList<Integer>();
myList.add(5);
myList.add(7);

And with a wrapper method

public void addMember(Integer x) {
    myList.add(x);
};

Try to do...

 DELIMITER $$
        CREATE TRIGGER aumentarsalario

          if (NEW.SALARIO < 900) THEN 
             set NEW.SALARIO = NEW.SALARIO + (NEW.SALARIO * 0.1);
          END IF;
        END $$
  DELIMITER ;

I find this type of approach works for me:

Product     ProductDetail        Country
=========   ==================   =========
ProductId   ProductDetailId      CountryId
- etc -     ProductId            CountryName
            CountryId            Language
            ProductName          - etc -
            ProductDescription
            - etc -

The ProductDetail table holds all the translations (for product name, description etc..) in the languages you want to support. Depending on your app's requirements, you may wish to break the Country table down to use regional languages too.

JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm page.

One idea is to let the the browser know that it should redirect by adding a redirect variable to to the resulting object and checking for it in JQuery:

$(document).ready(function(){ 
    jQuery.ajax({ 
        type: "GET", 
        url: "populateData.htm", 
        dataType:"json", 
        data:"userId=SampleUser", 
        success:function(response){ 
            if (response.redirect) {
                window.location.href = response.redirect;
            }
            else {
                // Process the expected results...
            }
        }, 
     error: function(xhr, textStatus, errorThrown) { 
            alert('Error!  Status = ' + xhr.status); 
         } 

    }); 
}); 

You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1") and in JQuery you do on success(!):

//....
        success:function(response){ 
            if (response.getResponseHeader('REQUIRES_AUTH') === '1'){ 
                window.location.href = 'login.htm'; 
            }
            else {
                // Process the expected results...
            }
        }
//....

Hope that helps.

My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.

>>> d={'a':1,'b':2,'c':3}
>>> for kv in d.items():
...     print kv[0],'\t',kv[1]
... 
a   1
c   3
b   2

@Controller
@RequestMapping(value = "/topic")
@Transactional

i solve this problem by adding @Transactional,i think this can make session open

I guess that what you want to do is an UNION of both tables.

If both tables have the same columns then you can just do

SELECT category_id, col1, col2, col3
  FROM items_a
UNION 
SELECT category_id, col1, col2, col3 
  FROM items_b

Else, you might have to do something like

SELECT category_id, col1, col2, col3
  FROM items_a 
UNION 
SELECT category_id, col_1 as col1, col_2 as col2, col_3 as col3
  FROM items_b

Coping with Scoping is a good overview of Perl scoping rules. It's old enough that our is not discussed in the body of the text. It is addressed in the Notes section at the end.

The article talks about package variables and dynamic scope and how that differs from lexical variables and lexical scope.

Since the third version of Swift you can do the following:

let desiredString = NSString(data: yourData, encoding: String.Encoding.utf8.rawValue)

simialr to what Sunkas advised.

If you are working with bytes you could use the builtin bytearray. If you are working with other integral types look at the builtin array.

Specifically understand that a list is not an array.

If, for example, you are trying to create a buffer for reading file contents into you could use bytearray as follows (there are better ways to do this but the example is valid):

with open(FILENAME, 'rb') as f:
    data = bytearray(os.path.getsize(FILENAME))
    f.readinto(data)

In this snippet the bytearray memory is preallocated with the fixed length of FILENAMEs size in bytes. This preallocation allows the use of the buffer protocol to more efficiently read the file into a mutable buffer without an array copy. There are yet better ways to do this but I believe this provides one answer to your question.

Your view can reference some external table containing your parameters.

As others mentioned, the view in SQL Server cannot have external input parameters. However, you can easily fake a variable in your view using CTE. You can test-run it in your version of SQL Server.

CREATE VIEW vwImportant_Users AS
WITH params AS (
    SELECT 
    varType='%Admin%', 
    varMinStatus=1)
SELECT status, name 
    FROM sys.sysusers, params
    WHERE status > varMinStatus OR name LIKE varType

SELECT * FROM vwImportant_Users

yielding output:

status  name
12      dbo
0       db_accessadmin
0       db_securityadmin
0       db_ddladmin

also via JOIN

WITH params AS ( SELECT varType='%Admin%', varMinStatus=1)
SELECT status, name 
    FROM sys.sysusers INNER JOIN params ON 1=1
    WHERE status > varMinStatus OR name LIKE varType

also via CROSS APPLY

WITH params AS ( SELECT varType='%Admin%', varMinStatus=1)
SELECT status, name 
    FROM sys.sysusers CROSS APPLY params
    WHERE status > varMinStatus OR name LIKE varType

Oh no no! That's not how you redirect. It's far more simpler:

public class ModHelloWorld extends HttpServlet{
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException{
        response.sendRedirect("http://www.google.com");
    }
}

Also, it's a bad practice to write HTML code within a servlet. You should consider putting all that markup into a JSP and invoking the JSP using:

response.sendRedirect("/path/to/mynewpage.jsp");

Let me answer this question:
First of all, using annotations as our configure method is just a convenient method instead of coping the endless XML configuration file.

The @Idannotation is inherited from javax.persistence.Id, indicating the member field below is the primary key of current entity. Hence your Hibernate and spring framework as well as you can do some reflect works based on this annotation. for details please check javadoc for Id

The @GeneratedValue annotation is to configure the way of increment of the specified column(field). For example when using Mysql, you may specify auto_increment in the definition of table to make it self-incremental, and then use

@GeneratedValue(strategy = GenerationType.IDENTITY)

in the Java code to denote that you also acknowledged to use this database server side strategy. Also, you may change the value in this annotation to fit different requirements.

1. Define Sequence in database

For instance, Oracle has to use sequence as increment method, say we create a sequence in Oracle:

create sequence oracle_seq;

2. Refer the database sequence

Now that we have the sequence in database, but we need to establish the relation between Java and DB, by using @SequenceGenerator:

@SequenceGenerator(name="seq",sequenceName="oracle_seq")

sequenceName is the real name of a sequence in Oracle, name is what you want to call it in Java. You need to specify sequenceName if it is different from name, otherwise just use name. I usually ignore sequenceName to save my time.

3. Use sequence in Java

Finally, it is time to make use this sequence in Java. Just add @GeneratedValue:

@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="seq")

The generator field refers to which sequence generator you want to use. Notice it is not the real sequence name in DB, but the name you specified in name field of SequenceGenerator.

4. Complete

So the complete version should be like this:

public class MyTable
{
    @Id
    @SequenceGenerator(name="seq",sequenceName="oracle_seq")        
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="seq")               
    private Integer pid;
}

Now start using these annotations to make your JavaWeb development easier.

There is no automated uninstaller.

You have to remove Eclipse manually. At least Eclipse does not write anything in the system registry, so deleting some directories and files is enough.

Note: I use Unix style paths in this answer but the locations should be the same on Windows or Unix systems, so ~ refers to the user home directory even on Windows.

Why is there no uninstaller?

According to this discussion about uninstalling Eclipse, the reasoning for not providing an uninstaller is that the Eclipse installer is supposed to just automate a few tasks that in the past had to be done manually (like downloading and extracting Eclipse and adding shortcuts), so they also can be undone manually. There is no entry in "Programs and Features" because the installer does not register anything in the system registry.

How to quickly uninstall Eclipse

Just delete the Eclipse directory and any desktop and start menu shortcuts and be done with it, if you don't mind a few leftover files.

In my opinion this is generally enough and I would stop here, because multiple Eclipse installations can share some files and you don't accidentally want to delete those shared files. You also keep all your projects.

How to completely uninstall Eclipse

If you really want to remove Eclipse without leaving any traces, you have to manually delete

• all desktop and start menu shortcuts
• the installation directory (e.g. ~/eclipse/photon/)
• the p2 bundle pool (which is often shared with other eclipse installations)

The installer has a "Bundle Pools" menu entry which lists the locations of all bundle pools. If you have other Eclipse installations on your system you can use the "Cleanup Agent" to clean up unused bundles. If you don't have any other Eclipse installations you can delete the whole bundle pool directory instead (by default ~/p2/).

If you want to completely remove the Eclipse installer too, delete the installer's executable and the ~/.eclipse/ directory.

Depending on what kind of work you did with Eclipse, there can be more directories that you may want to delete. If you used Maven, then ~/.m2/ contains the Maven cache and settings (shared with Maven CLI and other IDEs). If you develop Eclipse plugins, then there might be JUnit workspaces from test runs, next to you Eclipse workspace. Likewise other build tools and development environments used in Eclipse could have created similar directories.

How to delete all projects

If you want to delete your projects and workspace metadata, you have to delete your workspace(s). The default workspace location is ´~/workspace/´. You can also search for the .metadata directory to get all Eclipse workspaces on your machine.

If you are working with Git projects, these are generally not saved in the workspace but in the ~/git/ directory.

This can be achieved by

<input type="file" accept="image/*" /> 

But this is not a good way. you have to code on the server side to check the file an image or not.

Check if image file is an actual image or fake image

if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    }
    else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}

Basically, if you are developing a client- server application. You may use WCF -> in order to make connection between client and server, WPF -> as client side to present the data.

This solution has the benefit of showing the URL of the linked-to page on hover, as most browsers do by default, instead of history.go(-1) or similar:

<script>
    document.write('<a href="' + document.referrer + '">Go Back</a>');
</script>

Unlike in the case of Angular, in React.js you need to update the state manually. You can do something like this:

<input
    className="form-control"
    type="text" value={this.state.name}
    id={'todoName' + this.props.id}
    onChange={e => this.onTodoChange(e.target.value)}
/>

And then in the function:

onTodoChange(value){
        this.setState({
             name: value
        });
    }

Also, you can set the initial state in the constructor of the component:

  constructor (props) {
    super(props);
    this.state = {
        updatable: false,
        name: props.name,
        status: props.status
    };
  }

If you do not care about the data in management database; i.e. users, vhosts, messages etc., and neither about other queues, then you can reset via commandline by running the following commands in order:

WARNING: In addition to the queues, this will also remove any users and vhosts, you have configured on your RabbitMQ server; and will delete any persistent messages

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app

The rabbitmq documentation says that the reset command:

Returns a RabbitMQ node to its virgin state.

Removes the node from any cluster it belongs to, removes all data from the management database, such as configured users and vhosts, and deletes all persistent messages.

So, be careful using it.

From my own question:

start /b myProgram.exe params...

works if you start the program from an existing DOS session.

If not, call a vb script

wscript.exe invis.vbs myProgram.exe %*

The Windows Script Host Run() method takes:

• intWindowStyle : 0 means "invisible windows"
• bWaitOnReturn : false means your first script does not need to wait for your second script to finish

Here is invis.vbs:

set args = WScript.Arguments
num = args.Count

if num = 0 then
    WScript.Echo "Usage: [CScript | WScript] invis.vbs aScript.bat <some script arguments>"
    WScript.Quit 1
end if

sargs = ""
if num > 1 then
    sargs = " "
    for k = 1 to num - 1
        anArg = args.Item(k)
        sargs = sargs & anArg & " "
    next
end if

Set WshShell = WScript.CreateObject("WScript.Shell")

WshShell.Run """" & WScript.Arguments(0) & """" & sargs, 0, False

In Linux I've resolved this by deleting all the folders with names starting as ".AndroidStudio" in my home directory and then rerunning the Android Studio.

The "Leader key" is a way of extending the power of VIM's shortcuts by using sequences of keys to perform a command. The default leader key is backslash. Therefore, if you have a map of <Leader>Q, you can perform that action by typing \Q.

Wood-eye be careful. After looking at all this code, I feel obligated to post:

Let's start with the shortest, but very strict way:

var str = "true";
var mybool = JSON.parse(str);

And end with a proper, more tolerant way:

var parseBool = function(str) 
{
    // console.log(typeof str);
    // strict: JSON.parse(str)

    if(str == null)
        return false;

    if (typeof str === 'boolean')
    {
        if(str === true)
            return true;

        return false;
    } 

    if(typeof str === 'string')
    {
        if(str == "")
            return false;

        str = str.replace(/^\s+|\s+$/g, '');
        if(str.toLowerCase() == 'true' || str.toLowerCase() == 'yes')
            return true;

        str = str.replace(/,/g, '.');
        str = str.replace(/^\s*\-\s*/g, '-');
    }

    // var isNum = string.match(/^[0-9]+$/) != null;
    // var isNum = /^\d+$/.test(str);
    if(!isNaN(str))
        return (parseFloat(str) != 0);

    return false;
}

Testing:

var array_1 = new Array(true, 1, "1",-1, "-1", " - 1", "true", "TrUe", "  true  ", "  TrUe", 1/0, "1.5", "1,5", 1.5, 5, -3, -0.1, 0.1, " - 0.1", Infinity, "Infinity", -Infinity, "-Infinity"," - Infinity", " yEs");

var array_2 = new Array(null, "", false, "false", "   false   ", " f alse", "FaLsE", 0, "00", "1/0", 0.0, "0.0", "0,0", "100a", "1 00", " 0 ", 0.0, "0.0", -0.0, "-0.0", " -1a ", "abc");


for(var i =0; i < array_1.length;++i){ console.log("array_1["+i+"] ("+array_1[i]+"): " + parseBool(array_1[i]));}

for(var i =0; i < array_2.length;++i){ console.log("array_2["+i+"] ("+array_2[i]+"): " + parseBool(array_2[i]));}

for(var i =0; i < array_1.length;++i){ console.log(parseBool(array_1[i]));}
for(var i =0; i < array_2.length;++i){ console.log(parseBool(array_2[i]));}

Add the below code

input[type="submit"]:hover {
    border: 1px solid #999;
    color: #000;
}

If you need only for these button then you can add id name

#paginate input[type="submit"]:hover {
    border: 1px solid #999;
    color: #000;
}

DEMO

Simply use

java.util.Collections.sort(list)

without String.CASE_INSENSITIVE_ORDER comparator parameter.

I understand that this is fairly old question and has some pretty good answers. But, here is my two cents for the sake of completeness.

As per the official documentation, there are four ways, you can allow complete access for robots to access your site.

Clean:

Specify a global matcher with a disallow segment as mentioned by @unor. So your /robots.txt looks like this.

User-agent: *
Disallow:

The hack:

Create a /robots.txt file with no content in it. Which will default to allow all for all type of Bots.

I don't care way:

Do not create a /robots.txt altogether. Which should yield the exact same results as the above two.

The ugly:

From the robots documentation for meta tags, You can use the following meta tag on all your pages on your site to let the Bots know that these pages are not supposed to be indexed.

<META NAME="ROBOTS" CONTENT="NOINDEX">

In order for this to be applied to your entire site, You will have to add this meta tag for all of your pages. And this tag should strictly be placed under your HEAD tag of the page. More about this meta tag here.

Analogous to @Resh32, but without the need to use the USE statement:

SELECT TABLE_NAME,
       COLUMN_NAME,
       CONSTRAINT_NAME,
       REFERENCED_TABLE_NAME,
       REFERENCED_COLUMN_NAME
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE TABLE_SCHEMA = "database_name" 
      AND TABLE_NAME = "table_name" 
      AND REFERENCED_COLUMN_NAME IS NOT NULL;

Useful, e.g. using the ORM.

std::bitset has a .to_string() method that returns a std::string holding a text representation in binary, with leading-zero padding.

Choose the width of the bitset as needed for your data, e.g. std::bitset<32> to get 32-character strings from 32-bit integers.

#include <iostream>
#include <bitset>

int main()
{
    std::string binary = std::bitset<8>(128).to_string(); //to binary
    std::cout<<binary<<"\n";

    unsigned long decimal = std::bitset<8>(binary).to_ulong();
    std::cout<<decimal<<"\n";
    return 0;
}

EDIT: Please do not edit my answer for Octal and Hexadecimal. The OP specifically asked for Decimal To Binary.

<script type="text/javascript">

Try it out here: http://jsfiddle.net/2K3Vp/

For Spring 2

val hostName = InetAddress.getLocalHost().hostName

var webServerPort: Int = 0
@Configuration
class ApplicationListenerWebServerInitialized : ApplicationListener<WebServerInitializedEvent> {
    override fun onApplicationEvent(event: WebServerInitializedEvent) {
        webServerPort = event.webServer.port
    }
}

then you can use also webServerPort from anywhere...

I also struggled finding articles on how to just generate the token part. I never found one and wrote my own. So if it helps:

The things to do are:

• Create a new web application
• Install the following NuGet packages:
  • Microsoft.Owin
  • Microsoft.Owin.Host.SystemWeb
  • Microsoft.Owin.Security.OAuth
  • Microsoft.AspNet.Identity.Owin
• Add a OWIN startup class

Then create a HTML and a JavaScript (index.js) file with these contents:

var loginData = 'grant_type=password&[email protected]&password=test123';

var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function () {
    if (xmlhttp.readyState === 4 && xmlhttp.status === 200) {
        alert(xmlhttp.responseText);
    }
}
xmlhttp.open("POST", "/token", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(loginData);

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
    <script type="text/javascript" src="index.js"></script>
</body>
</html>

The OWIN startup class should have this content:

using System;
using System.Security.Claims;
using Microsoft.Owin;
using Microsoft.Owin.Security.OAuth;
using OAuth20;
using Owin;

[assembly: OwinStartup(typeof(Startup))]

namespace OAuth20
{
    public class Startup
    {
        public static OAuthAuthorizationServerOptions OAuthOptions { get; private set; }

        public void Configuration(IAppBuilder app)
        {
            OAuthOptions = new OAuthAuthorizationServerOptions()
            {
                TokenEndpointPath = new PathString("/token"),
                Provider = new OAuthAuthorizationServerProvider()
                {
                    OnValidateClientAuthentication = async (context) =>
                    {
                        context.Validated();
                    },
                    OnGrantResourceOwnerCredentials = async (context) =>
                    {
                        if (context.UserName == "[email protected]" && context.Password == "test123")
                        {
                            ClaimsIdentity oAuthIdentity = new ClaimsIdentity(context.Options.AuthenticationType);
                            context.Validated(oAuthIdentity);
                        }
                    }
                },
                AllowInsecureHttp = true,
                AccessTokenExpireTimeSpan = TimeSpan.FromDays(1)
            };

            app.UseOAuthBearerTokens(OAuthOptions);
        }
    }
}

Run your project. The token should be displayed in the pop-up.

There is a gem called active_record_union that might be what you are looking for.

It's example usages is the following:

current_user.posts.union(Post.published)
current_user.posts.union(Post.published).where(id: [6, 7])
current_user.posts.union("published_at < ?", Time.now)
user_1.posts.union(user_2.posts).union(Post.published)
user_1.posts.union_all(user_2.posts)

Try crypto.randomBytes():

require('crypto').randomBytes(48, function(err, buffer) {
  var token = buffer.toString('hex');
});

The 'hex' encoding works in node v0.6.x or newer.

If you don't want to use Windows Forms nor edit manifest files, I came up with a very simple hack using WPF's SaveAs dialog for actually selecting a directory.

No using directive needed, you may simply copy-paste the code below !

It should still be very user-friendly and most people will never notice.

The idea comes from the fact that we can change the title of that dialog, hide files, and work around the resulting filename quite easily.

It is a big hack for sure, but maybe it will do the job just fine for your usage...

In this example I have a textbox object to contain the resulting path, but you may remove the related lines and use a return value if you wish...

// Create a "Save As" dialog for selecting a directory (HACK)
var dialog = new Microsoft.Win32.SaveFileDialog();
dialog.InitialDirectory = textbox.Text; // Use current value for initial dir
dialog.Title = "Select a Directory"; // instead of default "Save As"
dialog.Filter = "Directory|*.this.directory"; // Prevents displaying files
dialog.FileName = "select"; // Filename will then be "select.this.directory"
if (dialog.ShowDialog() == true) {
    string path = dialog.FileName;
    // Remove fake filename from resulting path
    path = path.Replace("\\select.this.directory", "");
    path = path.Replace(".this.directory", "");
    // If user has changed the filename, create the new directory
    if (!System.IO.Directory.Exists(path)) {
        System.IO.Directory.CreateDirectory(path);
    }
    // Our final value is in path
    textbox.Text = path;
}

The only issues with this hack are :

• Acknowledge button still says "Save" instead of something like "Select directory", but in a case like mines I "Save" the directory selection so it still works...
• Input field still says "File name" instead of "Directory name", but we can say that a directory is a type of file...
• There is still a "Save as type" dropdown, but its value says "Directory (*.this.directory)", and the user cannot change it for something else, works for me...

Most people won't notice these, although I would definitely prefer using an official WPF way if microsoft would get their heads out of their asses, but until they do, that's my temporary fix.

So far all proposed solutions work with separate char items, not code points. I'd like to propose two solutions to properly handle surrogate pairs as well (those are characters from U+10000 to U+10FFFF, composed of two char items).

1) One-line O(n logn) solution which utilizes Java 8 CharSequence.codePoints() stream:

static boolean areAnagrams(CharSequence a, CharSequence b) {
    return Arrays.equals(a.codePoints().sorted().toArray(),
                         b.codePoints().sorted().toArray());
}

2) Less elegant O(n) solution (in fact, it will be faster only for long strings with low chances to be anagrams):

static boolean areAnagrams(CharSequence a, CharSequence b) {
    int len = a.length();
    if (len != b.length())
        return false;

    // collect codepoint occurrences in "a"
    Map<Integer, Integer> ocr = new HashMap<>(64);
    a.codePoints().forEach(c -> ocr.merge(c, 1, Integer::sum));

    // for each codepoint in "b", look for matching occurrence
    for (int i = 0, c = 0; i < len; i += Character.charCount(c)) {
        int cc = ocr.getOrDefault((c = Character.codePointAt(b, i)), 0);
        if (cc == 0)                        
            return false;            
        ocr.put(c, cc - 1);
    }
    return true;
}

You should consider that a "true value" is everything except 0 and not only 1. So instead of 1=1 you should write 1<>0.

Because when you will use parameter (@param <> 0) you could have some conversion issue.

The most know is Access which translate True value on control as -1 instead of 1.

I made this simple Notification wrapper. It works on Chrome, Safari and Firefox.

Probably on Opera, IE and Edge as well but I haven't tested it yet.

Just get the notify.js file from here https://github.com/gravmatt/js-notify and put it into your page.

Get it on Bower

$ bower install js-notify

This is how it works:

notify('title', {
    body: 'Notification Text',
    icon: 'path/to/image.png',
    onclick: function(e) {}, // e -> Notification object
    onclose: function(e) {},
    ondenied: function(e) {}
  });

You have to set the title but the json object as the second argument is optional.

try this:-

select to_char(to_date('01/10/2017','dd/mm/yyyy'),'fmMonth fmDD,YYYY') from dual;

select to_char(sysdate,'fmMonth fmDD,YYYY') from dual;

code for a simple copy.

cp -r ./SourceFolder ./DestFolder

code for a copy with success result

cp -rv ./SourceFolder ./DestFolder

code for Forcefully if source contains any readonly file it will also copy

cp -rf ./SourceFolder ./DestFolder

for details help

cp --help

This function should do what you want:

char* readLine( FILE* file )
 {
 char buffer[1024];
 char* result = 0;
 int length = 0;

 while( !feof(file) )
  {
  fgets( buffer, sizeof(buffer), file );
  int len = strlen(buffer);
  buffer[len] = 0;

  length += len;
  char* tmp = (char*)malloc(length+1);
  tmp[0] = 0;

  if( result )
   {
   strcpy( tmp, result );
   free( result );
   result = tmp;
   }

  strcat( result, buffer );

  if( strstr( buffer, "\n" ) break;
  }

 return result;
 }

char* line = readLine( stdin );
/* Use it */
free( line );

I hope this helps.

Yes. The sequence doesn't have the 54th item.

I've successfully used int(x or 0) for this type of error, so long as None should equate to 0 in the logic. Note that this will also resolve to 0 in other cases where testing x returns False. e.g. empty list, set, dictionary or zero length string. Sorry, Kindall already gave this answer.

First-class functions

It's not really a hidden feature, but the fact that functions are first class objects is simply great. You can pass them around like any other variable.

>>> def jim(phrase):
...   return 'Jim says, "%s".' % phrase
>>> def say_something(person, phrase):
...   print person(phrase)

>>> say_something(jim, 'hey guys')
'Jim says, "hey guys".'

Check if the string is not null then convert the first character to upper case and the rest of them to lower case:

public static string FirstCharToUpper(string str)
{
    return str?.First().ToString().ToUpper() + str?.Substring(1).ToLower();
}

Trailing whitespace is any spaces or tabs after the last non-whitespace character on the line until the newline.

In your posted question, there is one extra space after try:, and there are 12 extra spaces after pass:

>>> post_text = '''\
...             if self.tagname and self.tagname2 in list1:
...                 try: 
...                     question = soup.find("div", "post-text")
...                     title = soup.find("a", "question-hyperlink")
...                     self.list2.append(str(title)+str(question)+url)
...                     current += 1
...                 except AttributeError:
...                     pass            
...             logging.info("%s questions passed, %s questions \
...                 collected" % (count, current))
...             count += 1
...         return self.list2
... '''
>>> for line in post_text.splitlines():
...     if line.rstrip() != line:
...         print(repr(line))
... 
'                try: '
'                    pass            '

See where the strings end? There are spaces before the lines (indentation), but also spaces after.

Use your editor to find the end of the line and backspace. Many modern text editors can also automatically remove trailing whitespace from the end of the line, for example every time you save a file.

You can't guarantee that you're always going to get String objects back, or that the object you're working with in the List implements a way to ignore case.

If you do want to compare Strings in a collection to something independent of case, you'd want to iterate over the collection and compare them without case.

String word = "Some word";
List<String> aList = new ArrayList<>(); // presume that the list is populated

for(String item : aList) {
    if(word.equalsIgnoreCase(item)) {
        // operation upon successful match
    }
}

I had to encounter a situation as such, and simply, the

str_replace("\/","/",$variable)

did work for me.

By far the most practical answer is the one given by tvanfosson, all i can do is give you an updated version with ES6:

setInterval( ()=>{ funca(10,3); }, 500);

Visibility : Hidden Vs Collapsed

Consider following code which only shows three Labels and has second Label visibility as Collapsed:

 <StackPanel Orientation="Horizontal" VerticalAlignment="Top" HorizontalAlignment="Center">
    <StackPanel.Resources>
        <Style TargetType="Label">
            <Setter Property="Height" Value="30" />
            <Setter Property="Margin" Value="0"/>
            <Setter Property="BorderBrush" Value="Black"/>
            <Setter Property="BorderThickness" Value="1" />
        </Style>
    </StackPanel.Resources>
    <Label Width="50" Content="First"/>
    <Label Width="50" Content="Second" Visibility="Collapsed"/>
    <Label Width="50" Content="Third"/>
</StackPanel>

Output Collapsed:

Now change the second Label visibility to Hiddden.

<Label Width="50" Content="Second" Visibility="Hidden"/>

Output Hidden:

As simple as that.

Edit: Today I learned the better way of doing this. Please see ircmaxell's answer.

Parse the output of SHOW COLUMNS FROM table;

Here's more about it here: http://dev.mysql.com/doc/refman/5.0/en/show-columns.html

I was facing the same problem and found a solution to get the code to work.

The code given in the android-Sdk/samples/android-?/ApiDemos works fine. Copy paste each folder in the android project and then in the MediaPlayerDemo_Video.java put the path of the video you want to stream in the path variable. It is left blank in the code.

The following video stream worked for me: http://www.pocketjourney.com/downloads/pj/video/famous.3gp

I know that RTSP protocol is to be used for streaming, but mediaplayer class supports http for streaming as mentioned in the code.

I googled for the format of the video and found that the video if converted to mp4 or 3gp using Quicktime Pro works fine for streaming.

I tested the final apk on android 2.1. The application dosent work on emulators well. Try it on devices.

I hope this helps..

You can get this issue if Apple update their terms. Simply log into your dev account and accept any updated terms and you should be good (you will need to goto Xcode -> project->signing and capabilities and retry the certificate check. This should get you going if terms are the issue.

For Windows, you can check the official Intel MKL optimization for TensorFlow wheels that are compiled with AVX2. This solution speeds up my inference ~x3.

conda install tensorflow-mkl

Here's another command line solution, but this works for Windows.

It requires winrar installed (edit the set winrar line to point to the winrar installation).

It also requires imagemagick to be installed and its path to be added in your commandline.

One last comment is I recommend running this before opening Eclipse for the first time (ie, fresh install). There are icons that get automatically unpacked from jars and saved in eclipse/configuration/org.eclips.osgi/... (potentially among other folders) and editing the .jar file prevents the icon from being resized. You might be able to delete this folder and it might autoextract again, but I can't confirm.

To run, just create a doubler.bat file in your eclipse/plugins directory and it should resize any icon smaller than 32x32 to that proportioned size.

Here's the code:

@echo off
set winrar="C:\Program Files\WinRAR\winrar.exe"
set startpath=%~dp0

::All *.jar in this folder
FOR %%G in (*.jar) do (call :EachJar "%%G")

GOTO :eof

:EachJar
  ::echo %1
  set nameWOQuotes=%~1
  mkdir "tmp\%nameWOQuotes%"
  ::copy "%nameWOQuotes%" "tmp\%nameWOQuotes%.bak" >NUL
  %winrar% x -inul "%nameWOQuotes%" *.jpg *.gif *.png *.tif *.tiff "tmp\%nameWOQuotes%\"
  ::pause
  cd "tmp\%nameWOQuotes%"
  FOR /R .\ %%H in (*.jpg *.gif *.png *.tif *.tiff) do ( 
    ::echo %nameWOQuotes%-%%~nxH >> "%startpath%\output.txt"
    identify "%%H" >> "%startpath%\output.txt"
   convert "%%H" -resize 32x32^< "%%H" )
  %winrar% a -r -u "%startpath%\%nameWOQuotes%" "*"
  cd "%startpath%"
  rmdir /s /q "tmp\%nameWOQuotes%"
Goto :eof

It creates a file output.txt and inserts all the ORIGINAL images metadata before it is converted, regardless of whether or not it changed size.

This answer is not the direct answer for the question. But it should help you figure out which solution fits best for your problem.

When analysing the problem you should activate the debug option -vv

Then rsync will output which files are included or excluded by which pattern:

building file list ... 
[sender] hiding file FILE1 because of pattern FILE1*
[sender] showing file FILE2 because of pattern *

You can easily fetch last inserted record Id

$user = User::create($userData);
$lastId = $user->value('id');

It's an awesome trick to fetch Id from the last inserted record in the DB.

Thread.interrupt() sets the interrupted status/flag of the target thread to true which when checked using Thread.interrupted() can help in stopping the endless thread. Refer http://www.yegor256.com/2015/10/20/interrupted-exception.html

You can create an extension method similar to ToDictionary() with the difference being that it allows duplicates. Something like:

    public static Dictionary<TKey, TElement> SafeToDictionary<TSource, TKey, TElement>(
        this IEnumerable<TSource> source, 
        Func<TSource, TKey> keySelector, 
        Func<TSource, TElement> elementSelector, 
        IEqualityComparer<TKey> comparer = null)
    {
        var dictionary = new Dictionary<TKey, TElement>(comparer);

        if (source == null)
        {
            return dictionary;
        }

        foreach (TSource element in source)
        {
            dictionary[keySelector(element)] = elementSelector(element);
        }

        return dictionary; 
    }

In this case, if there are duplicates, then the last value wins.

Just implement an Interface given by PHP JsonSerializable.

This happens when you index a row/column with a number that is larger than the dimensions of your dataframe. For instance, getting the eleventh column when you have only three.

import pandas as pd

df = pd.DataFrame({'Name': ['Mark', 'Laura', 'Adam', 'Roger', 'Anna'],
                   'City': ['Lisbon', 'Montreal', 'Lisbon', 'Berlin', 'Glasgow'],
                   'Car': ['Tesla', 'Audi', 'Porsche', 'Ford', 'Honda']})

You have 5 rows and three columns:

    Name      City      Car
0   Mark    Lisbon    Tesla
1  Laura  Montreal     Audi
2   Adam    Lisbon  Porsche
3  Roger    Berlin     Ford
4   Anna   Glasgow    Honda

Let's try to index the eleventh column (it doesn't exist):

df.iloc[:, 10] # there is obviously no 11th column

IndexError: single positional indexer is out-of-bounds

If you are a beginner with Python, remember that df.iloc[:, 10] would refer to the eleventh column.

This seems to be a serious limitation of WebDriver. Obviously waiting for an element will not imply the page being loaded, in particular the DOM can be fully build (onready state) whereby JS is still executing and CSS and images are still loading.

I believe the simplest solution is to set a JS variable upon the onload event after everything is initialized and check and wait for this JS variable in Selenium.

I actually came to this question looking for an answer myself, and after reading the given answers I can only agree that the best way to compare DB queries performance is to get real-world numbers because there are just to many variables to be taken into account BUT, I also think that comparing the numbers between them leads to no good in almost all cases. What I mean is that the numbers should always be compared with an acceptable number and definitely not compared with each other.

I can understand if one way of querying takes say 0.02 seconds and the other one takes 20 seconds, that's an enormous difference. But what if one way of querying takes 0.0000000002 seconds, and the other one takes 0.0000002 seconds ? In both cases one way is a whopping 1000 times faster than the other one, but is it really still "whopping" in the second case ?

Bottom line as I personally see it: if it performs well, go for the easy solution.

You'll want to:

• Read in an entire line from the console
• Tokenize the line, splitting along spaces.
• Place those split pieces into an array or list
• Step through that array/list, performing your prime/perfect/etc tests.

What has your class covered along these lines so far?

For nearly all programming purposes, VBA and VB 6.0 are the same thing.

VBA cannot compile your program into an executable binary. You'll always need the host (a Word file and MS Word, for example) to contain and execute your project. You'll also not be able to create COM DLLs with VBA.

Apart from that, there is a difference in the IDE - the VB 6.0 IDE is more powerful in comparison. On the other hand, you have tight integration of the host application in VBA. Application-global objects (like "ActiveDocument") and events are available without declaration, so application-specific programming is straight-forward.

Still, nothing keeps you from firing up Word, loading the VBA IDE and solving a problem that has no relation to Word whatsoever. I'm not sure if there is anything that VB 6.0 can do (technically), and VBA cannot. I'm looking for a comparison sheet on the MSDN though.

Use this to implement mask:

https://rawgit.com/RobinHerbots/jquery.inputmask/3.x/dist/jquery.inputmask.bundle.js

<input id="phn-number" class="ant-input" type="text" placeholder="(XXX) XXX-XXXX" data-inputmask-mask="(999) 999-9999">


jQuery( '#phn-number[data-inputmask-mask]' ).inputmask();

CSS does not have this ability. You would need to use client-side scripting.

I use

decimal Debitvalue = 1156.547m;
decimal DEBITAMT = Convert.ToDecimal(string.Format("{0:F2}", Debitvalue));

I think this way is better

const index = projects.findIndex(project => project.value==='jquery-ui');
projects[index].desc = "updated desc";

I had the same problem with foo.new being set to null for rows of foo that had no matching key in bar. I did something like this in Oracle:

update foo
set    foo.new = (select bar.new
                  from bar 
                  where foo.key = bar.key)
where exists (select 1
              from bar
              where foo.key = bar.key)

select case when [am or _pm] ='PM' and datepart(HOUR,time_received)<>12 
           then dateadd(hour,12,time_received) 
           else time_received 
       END 
from table

works

You should try this one:

Console.WriteLine("{0}.{1}.{2}", mon, da, yet);

See http://www.dotnetperls.com/console-writeline for more details.

Have you had a look at Enumerable.Union

This method excludes duplicates from the return set. This is different behavior to the Concat method, which returns all the elements in the input sequences including duplicates.

List<int> list1 = new List<int> { 1, 12, 12, 5};
List<int> list2 = new List<int> { 12, 5, 7, 9, 1 };
List<int> ulist = list1.Union(list2).ToList();

// ulist output : 1, 12, 5, 7, 9

I did a log file which prints data into text file using "Winston" log. The source code is here below,

const { createLogger, format, transports } = require('winston');
var fs = require('fs')
var logger = fs.createWriteStream('Data Log.txt', {`
flags: 'a' 
})
const os = require('os');
var sleep = require('system-sleep');
var endOfLine = require('os').EOL;
var t = '             ';var s = '         ';var q = '               ';
var array1=[];
var array2=[];
var array3=[];
var array4=[];

array1[0]  =  78;`
array1[1]  =  56;
array1[2]  =  24;
array1[3]  =  34;

for (var n=0;n<4;n++)
{
array2[n]=array1[n].toString();
}

for (var k=0;k<4;k++)
{
array3[k]=Buffer.from('                    ');
}

for (var a=0;a<4;a++)  
{
array4[a]=Buffer.from(array2[a]);
}

for (m=0;m<4;m++)
{
array4[m].copy(array3[m],0);
}

logger.write('Date'+q);
logger.write('Time'+(q+'  '))
logger.write('Data 01'+t);
logger.write('Data 02'+t); 
logger.write('Data 03'+t);
logger.write('Data 04'+t)

logger.write(endOfLine);
logger.write(endOfLine);
enter code here`enter code here`
}

function mydata()      //user defined function
{
logger.write(datechar+s);
logger.write(timechar+s);
for ( n = 0; n < 4; n++) 
{
logger.write(array3[n]);
}
logger.write(endOfLine); 
}

for (;;)
}
var now = new Date();
var dateFormat = require('dateformat');
var date = dateFormat(now,"isoDate");
var time = dateFormat(now, "h:MM:ss TT ");
var datechar = date.toString();
var timechar = time.toString();
mydata();
sleep(5*1000);
}

This is how I did for my CRUDManager class initialized in Angular controller, which later passed over to jQuery button-click event defined outside the controller:

In Angular Controller:

        // Note that I can even pass over the $scope to my CRUDManager's constructor.
        var crudManager = new CRUDManager($scope, contextData, opMode);

        crudManager.initialize()
            .then(() => {
                crudManager.dataBind();
                $scope.crudManager = crudManager;
                $scope.$apply();
            })
            .catch(error => {
                alert(error);
            });

In jQuery Save button click event outside the controller:

    $(document).on("click", "#ElementWithNgControllerDefined #btnSave", function () {
        var ngScope = angular.element($("#ElementWithNgControllerDefined")).scope();
        var crudManager = ngScope.crudManager;
        crudManager.saveData()
            .then(finalData => {
               alert("Successfully saved!");
            })
            .catch(error => {
               alert("Failed to save.");
            });
    });

This is particularly important and useful when your jQuery events need to be placed OUTSIDE OF CONTROLLER in order to prevent it from firing twice.

Sometimes it is useful to temporarily change Git's case sensitivity.

Method #1 - Change case sensitivity for a single command:

git -c core.ignorecase=true checkout mybranch to turn off case-sensitivity for a single checkout command. Or more generally: git -c core.ignorecase= <<true or false>> <<command>>. (Credit to VonC for suggesting this in the comments.)

Method #2 - Change case sensitivity for multiple commands:

To change the setting for longer (e.g. if multiple commands need to be run before changing it back):

1. git config core.ignorecase (this returns the current setting, e.g. false).
2. git config core.ignorecase <<true or false>> - set the desired new setting.
3. ...Run multiple other commands...
4. git config core.ignorecase <<false or true>> - set config value back to its previous setting.

Terminal opens a login shell. This means, ~/.bash_profile will get executed, ~/.bashrc not.

The solution on most systems is to "require" the ~/.bashrc in the ~/.bash_profile: just put this snippet in your ~/.bash_profile:

[[ -s ~/.bashrc ]] && source ~/.bashrc

To use video extensions that are MKV. You should use video, not source

For example :

  <!-- mkv -->
  <video width="320" height="240" controls src="assets/animation.mkv"></video>
<!-- mp4 -->
  <video width="320" height="240" controls>
    <source src="assets/animation.mp4" type="video/mp4" />
  </video>

Variable interpolation does not happen in single quotes. You need to use double quotes as:

$i = 1
echo "<p class=\"paragraph$i\"></p>";
++i;

To use the Bash builtin time rather than /bin/time you can set this variable:

TIMEFORMAT='%3R'

which will output the real time that looks like this:

5.009

or

65.233

The number specifies the precision and can range from 0 to 3 (the default).

You can use:

TIMEFORMAT='%3lR'

to get output that looks like:

3m10.022s

The l (ell) gives a long format.

There is a much easier way to run JavaScript, no configuration needed:

1. Install the Code Runner Extension
2. Open the JavaScript code file in Text Editor, then use shortcut Control+Alt+N (or ^ Control+? Option+N on macOS), or press F1 and then select/type Run Code, the code will run and the output will be shown in the Output Window.

Besides, you could select part of the JavaScript code and run the code snippet. The extension also works with unsaved files, so you can just create a file, change it to Javascript and write code fast (for when you just need to try something quick). Very convenient!

SUMIF didn't worked for me, had to use SUMIFS.

=SUMIFS(TableAmount,TableMonth,"January")

TableAmount is the table to sum the values, TableMonth the table where we search the condition and January, of course, the condition to meet.

Hope this can help someone!

A log of your commands may be available in your shell history.

history

If seeing the list of executed commands fly by isn't for you, export the list into a file.

history > path/to/file

You can restrict the exported dump to only show commands with "git" in them by piping it with grep

history | grep "git " > path/to/file

The history may contain lines formatted as such

518  git status -s
519  git commit -am "injects sriracha to all toppings, as required"

Using the number you can re-execute the command with an exclamation mark

$ !518
git status -s

You can make a static property that initializes and returns a default "rational" number:

public static Rational One => new Rational(0, 1); 

And use it like:

var rat = Rational.One;

Set Python 3.5 with higher priority

sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.5 2

Check the result

sudo update-alternatives --config python
python -V

I'll right simple example show you the right way to use wait and notify in Java. So I'll create two class named ThreadA & ThreadB. ThreadA will call ThreadB.

public class ThreadA {
    public static void main(String[] args){
        ThreadB b = new ThreadB();//<----Create Instance for seconde class
        b.start();//<--------------------Launch thread

        synchronized(b){
            try{
                System.out.println("Waiting for b to complete...");
                b.wait();//<-------------WAIT until the finish thread for class B finish
            }catch(InterruptedException e){
                e.printStackTrace();
            }

            System.out.println("Total is: " + b.total);
        }
    }
} 

and for Class ThreadB:

class ThreadB extends Thread{
    int total;
    @Override
    public void run(){
        synchronized(this){
            for(int i=0; i<100 ; i++){
                total += i;
            }
            notify();//<----------------Notify the class wich wait until my    finish 
//and tell that I'm finish
            }
        }
    }

SELECT * FROM information_schema.columns
WHERE table_schema = DATABASE()
ORDER BY table_name, ordinal_position

Since I don't have enough rep to comment, here's a minor improvement (in my view) over nick rulez's excellent answer: replacing WHERE table_schema = 'your_db' with WHERE table_schema = DATABASE().

I assume you mean list and not array? There is such a thing as an array in Python, but more often than not you want a list instead of an array.

The way to check if a list contains a value is to use in:

if paid[j] in d:
    # ...

If using SQL Server, SqlBulkCopy.WriteToServer(DataTable)

• SqlBulkCopy.WriteToServer Method (DataTable)

Or also with SQL Server, you can write it to a .csv and use BULK INSERT

• BULK INSERT (Transact-SQL)

If using MySQL, you could write it to a .csv and use LOAD DATA INFILE

• LOAD DATA INFILE Syntax

If using Oracle, you can use the array binding feature of ODP.NET

• Bulk Insert to Oracle using .NET

If SQLite:

NSTimer has been renamed to Timer in Swift 4.2. this syntax will work in 4.2:

let timer = Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(UIMenuController.update), userInfo: nil, repeats: true)

The following class might come quite handy:

struct Error : std::exception
{
    char text[1000];

    Error(char const* fmt, ...) __attribute__((format(printf,2,3))) {
        va_list ap;
        va_start(ap, fmt);
        vsnprintf(text, sizeof text, fmt, ap);
        va_end(ap);
    }

    char const* what() const throw() { return text; }
};

Usage example:

throw Error("Could not load config file '%s'", configfile.c_str());
