In lightsail a virtual machine, SSD-based storage, data transfer, DNS management, and a static IP are all offered as a package. Whereas in normal case you provision an EC2 instance and then setup the rest of these things.Also Bandwidth included in the price, no security groups to set up, no need to worry about EBS volumes sizing.

So many complicated methods... Just find all "Titled" group and join its lower cased variant with underscore.

>>> import re
>>> def camel_to_snake(string):
...     groups = re.findall('([A-z0-9][a-z]*)', string)
...     return '_'.join([i.lower() for i in groups])
...
>>> camel_to_snake('ABCPingPongByTheWay2KWhereIsOurBorderlands3???')
'a_b_c_ping_pong_by_the_way_2_k_where_is_our_borderlands_3'

If you don't want make numbers like first character of group or separate group - you can use ([A-z][a-z0-9]*) mask.

SupressFinalize tells the system that whatever work would have been done in the finalizer has already been done, so the finalizer doesn't need to be called. From the .NET docs:

Objects that implement the IDisposable interface can call this method from the IDisposable.Dispose method to prevent the garbage collector from calling Object.Finalize on an object that does not require it.

In general, most any Dispose() method should be able to call GC.SupressFinalize(), because it should clean up everything that would be cleaned up in the finalizer.

SupressFinalize is just something that provides an optimization that allows the system to not bother queuing the object to the finalizer thread. A properly written Dispose()/finalizer should work properly with or without a call to GC.SupressFinalize().

For Win32:

While GetSystemInfo() gets you the number of logical processors, use GetLogicalProcessorInformationEx() to get the number of physical processors.

Pure Bash, without an extra process:

for (( COUNTER=0; COUNTER<=10; COUNTER+=2 )); do

git add . equals git add -A . adds files to index only from current and children folders.

git add -A adds files to index from all folders in working tree.

P.S.: information relates to Git 2.0 (2014-05-28).

I am new to Rust, but this solution seems to work:

#[macro_use]
extern crate lazy_static;

use std::sync::{Arc, Mutex};

lazy_static! {
    static ref GLOBAL: Arc<Mutex<GlobalType> =
        Arc::new(Mutex::new(GlobalType::new()));
}

Another solution is to declare a crossbeam channel tx/rx pair as an immutable global variable. The channel should be bounded and can only hold 1 element. When you initialize the global variable, push the global instance into the channel. When using the global variable, pop the channel to acquire it and push it back when done using it.

Both solutions should provide a safe approach to using global variables.

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

There's nothing wrong with include file in head. It seems you forgot to add;. Please try this one:

<body onload="imageRefreshBig();">

But as per my knowledge semicolons are optional. You can try with ; but better debug code and see if chrome console gives any error.

I hope this helps.

You'll get this error as well if you are verifying that an extension method of an interface is called.

For example if you are mocking:

var mockValidator = new Mock<IValidator<Foo>>();
mockValidator
  .Verify(validator => validator.ValidateAndThrow(foo, null));

You will get the same exception because .ValidateAndThrow() is an extension on the IValidator<T> interface.

public static void ValidateAndThrow<T>(this IValidator<T> validator, T instance, string ruleSet = null)...

Case 1 : Yes, this works fine.

Case 2 : This will fail with the error ORA-01441 : cannot decrease column length because some value is too big.

Share and enjoy.

The purist way to do this would be to add event handlers to the button, instead of mixing behavior with the content (LSM, Layered Semantic Markup)

<input type="button" value="Increment" id="increment"/>

<script type="text/javascript">
    var count = 0;
    // JQuery way
    $('#increment').click(function (e) {
        e.preventDefault();
        count++;
    });
    // YUI way
    YAHOO.util.Event.on('increment', 'click', function (e) {
        YAHOO.util.Event.preventDefault(e);
        count++;
    });
    // Simple way
    document.getElementById('increment').onclick = function (e) {
        count++;
        if (e.preventDefault) {
            e.preventDefault();
        }
        e.returnValue = false;
    };
</script>

I made some minor modification to you code and tested it with a spring project that I have and it works, The logic will only work with POST if I use GET it throws an error with invalid request. Also in your ajax call I commented out commit(true), the browser debugger flagged and error that it is not defined. Just modify the url to fit your Spring project architecture.

 $.ajax({ 
                    url: "/addDepartment", 
                    method: 'POST', 
                    dataType: 'json', 
                    data: "{\"message\":\"abc\",\"success\":true}",
                    contentType: 'application/json',
                    mimeType: 'application/json',
                    success: function(data) { 
                        alert(data.success + " " + data.message);
                        //commit(true);
                    },
                    error:function(data,status,er) { 
                        alert("error: "+data+" status: "+status+" er:"+er);
                    }
                });



@RequestMapping(value="/addDepartment", method=RequestMethod.POST)
  public AjaxResponse addDepartment(@RequestBody final AjaxResponse  departmentDTO)
  {
    System.out.println("addDepartment: >>>>>>> "+departmentDTO);
    AjaxResponse response=new AjaxResponse();
    response.setSuccess(departmentDTO.isSuccess());
    response.setMessage(departmentDTO.getMessage());
    return response;
  }

ENABLE is what you are looking for

USAGE: type this command once and then you are good to go. Your service will start automaticaly at boot up

 sudo systemctl enable postgresql

DISABLE exists as well ofc

Some DOC: freedesktop man systemctl

c = truediv(a, b)

This is the sort of thing that the CSS flexbox model will fix, because it will let you specify that each li will receive an equal proportion of the remaining width.

i used replace feature in Notepad++ and replaced " (without quotes) with " and result was valid json

By using pandas:

df.time_diff.quantile([0.25,0.5,0.75])


Out[793]: 
0.25    0.483333
0.50    0.500000
0.75    0.516667
Name: time_diff, dtype: float64

There's nothing deep happening here.. Basically, it's handy to test something to see if it's of a certain type (i.e. use 'as'). You would want to check the result of the 'as' call to see if the result is null.

When you expect a cast to work and you want the exception to be thrown, use the 'classic' method.

Use blur event to call your function when element loses focus :

$('#filter').blur(function() {
  $('#options').hide();
});

You need to pass in a sequence, but you forgot the comma to make your parameters a tuple:

cursor.execute('INSERT INTO images VALUES(?)', (img,))

Without the comma, (img) is just a grouped expression, not a tuple, and thus the img string is treated as the input sequence. If that string is 74 characters long, then Python sees that as 74 separate bind values, each one character long.

>>> len(img)
74
>>> len((img,))
1

If you find it easier to read, you can also use a list literal:

cursor.execute('INSERT INTO images VALUES(?)', [img])

For Bootstrap v4.1

Add the data-parent attribute to the collapse elements instead on the button.

<div id="myGroup">
<button class="btn dropdown" data-toggle="collapse" data-target="#keys"><i class="icon-chevron-right"></i> Keys  <span class="badge badge-info pull-right">X</span></button>
<button class="btn dropdown" data-toggle="collapse" data-target="#attrs"><i class="icon-chevron-right"></i> Attributes</button>
<button class="btn dropdown" data-toggle="collapse" data-target="#edit"><i class="icon-chevron-right"></i> Edit Details</button>

<div class="accordion-group">
    <div class="collapse indent" id="keys"  data-parent="#myGroup">
        keys
    </div>

    <div class="collapse indent" id="attrs"  data-parent="#myGroup">
        attrs
    </div>

    <div class="collapse" id="edit"  data-parent="#myGroup">
        edit
    </div>
</div>

Update to Swift 3

let image = UIImage(named: "name")
let button = UIButton(type: .custom)
button.frame = CGRect(x: 100, y: 100, width: 100, height: 100)
button.setImage(image, for: .normal)
button.addTarget(self, action: #selector(self.btnAbsRetClicked(_:)), for:.touchUpInside)
self.view.addSubview(button)

All the answers work but they always traverse the whole list. If I understand your question, you only need the first match. So you don't have to consider the rest of the list if you found your first match:

mylist = ['abc123', 'def456', 'ghi789']
sub = 'abc'
next((s for s in mylist if sub in s), None) # returns 'abc123'

If the match is at the end of the list or for very small lists, it doesn't make a difference, but consider this example:

import timeit

mylist = ['abc123'] + ['xyz123']*1000
sub = 'abc'

timeit.timeit('[s for s in mylist if sub in s]', setup='from __main__ import mylist, sub', number=100000)
# for me 7.949463844299316 with Python 2.7, 8.568840944994008 with Python 3.4
timeit.timeit('next((s for s in mylist if sub in s), None)', setup='from __main__ import mylist, sub', number=100000) 
# for me 0.12696599960327148 with Python 2.7, 0.09955992100003641 with Python 3.4

Just something to help you to start on.

A (simple idea of) binary tree search would be quite likely be implement in python according the lines:

def search(node, key):
    if node is None: return None  # key not found
    if key< node.key: return search(node.left, key)
    elif key> node.key: return search(node.right, key)
    else: return node.value  # found key

Now you just need to implement the scaffolding (tree creation and value inserts) and you are done.

Since assertThat which was the old answer is now deprecated, I am posting the correct solution:

assertTrue(objectUnderTest instanceof TargetObject);

Some time you miss below line. add this router will understand this.

module.exports = router;

Unfortunately, AFAIK you cannot run multiple SQL statements under one named query in Access in the traditional sense.

You can make several queries, then string them together with VBA (DoCmd.OpenQuery if memory serves).

You can also string a bunch of things together with UNION if you wish.

Found the answer on a blog and it's as simple as:

strtotime(date("Y"."-01-01")) -strtotime($newdate))/86400

And you'll get the days between the 2 dates.

raise SystemExit

this worked on the first try, where

self.destroy()
root.destroy()

did not

Found these docu on the google docu pages:

• row --- int --- top row of the range
• column --- int--- leftmost column of the range
• optNumRows --- int --- number of rows in the range.
• optNumColumns --- int --- number of columns in the range

In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns

edit

Using the example on the docu:

// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);

The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G

So you come to the range: C2:G8

Which model is the "best fitting model" depends on what you mean by "best". R has tools to help, but you need to provide the definition for "best" to choose between them. Consider the following example data and code:

x <- 1:10
y <- x + c(-0.5,0.5)

plot(x,y, xlim=c(0,11), ylim=c(-1,12))

fit1 <- lm( y~offset(x) -1 )
fit2 <- lm( y~x )
fit3 <- lm( y~poly(x,3) )
fit4 <- lm( y~poly(x,9) )
library(splines)
fit5 <- lm( y~ns(x, 3) )
fit6 <- lm( y~ns(x, 9) )

fit7 <- lm( y ~ x + cos(x*pi) )

xx <- seq(0,11, length.out=250)
lines(xx, predict(fit1, data.frame(x=xx)), col='blue')
lines(xx, predict(fit2, data.frame(x=xx)), col='green')
lines(xx, predict(fit3, data.frame(x=xx)), col='red')
lines(xx, predict(fit4, data.frame(x=xx)), col='purple')
lines(xx, predict(fit5, data.frame(x=xx)), col='orange')
lines(xx, predict(fit6, data.frame(x=xx)), col='grey')
lines(xx, predict(fit7, data.frame(x=xx)), col='black')

Which of those models is the best? arguments could be made for any of them (but I for one would not want to use the purple one for interpolation).

Same problem - easy fix for me.

To find the underlying problem I navigated to the actual swagger.json file which gave me the real error

/swagger/v1/swagger.json

The actual error displayed from this Url was

NotSupportedException: Ambiguous HTTP method for action  ... Actions require an explicit HttpMethod binding for Swagger/OpenAPI 3.0

The point being

Actions require an explicit HttpMethod

I then decorated my controller methods with [HttpGet]

[Route("GetFlatRows")]
 [HttpGet]
 public IActionResult GetFlatRows()
 {

Problem solved

One option would be to add your working directory to your Chrome "workspace" which allows Chrome to map local files to those on the page. It will then detect changes in the local files, and update the page in real-time.

This can be done from the "Sources" tab of Devtools:

Click on the "Filesystem" tab in the file browser sidebar, then click the +Plus sign button to "Add folder to workspace" - you will be prompted with a banner at the top of the screen to allow or deny local file access:

Once allowed, the folder will appear in the "Filesystem" tab on the left. Chrome will now attempt to associate each file in the filesystem tab with a file in the page. Sometimes you will need to reload the page once for this to function correctly.

Once this is done, Chrome should have no trouble picking up local changes, in fact you won't even need to reload to get the changes in many cases, and you can make edits to the local files directly from Devtools (which is extremely useful for CSS, it even comments out CSS lines when you toggle the checkboxes in the Styles tab).

More information on Workspaces in Chrome.

Reading Unicode from a file is therefore simple:

import codecs
with codecs.open('unicode.rst', encoding='utf-8') as f:
    for line in f:
        print repr(line)

It's also possible to open files in update mode, allowing both reading and writing:

with codecs.open('test', encoding='utf-8', mode='w+') as f:
    f.write(u'\u4500 blah blah blah\n')
    f.seek(0)
    print repr(f.readline()[:1])

EDIT: I'm assuming that your intended goal is just to be able to read the file properly into a string in Python. If you're trying to convert to an ASCII string from Unicode, then there's really no direct way to do so, since the Unicode characters won't necessarily exist in ASCII.

If you're trying to convert to an ASCII string, try one of the following:

1. Replace the specific unicode chars with ASCII equivalents, if you are only looking to handle a few special cases such as this particular example

2. Use the unicodedata module's normalize() and the string.encode() method to convert as best you can to the next closest ASCII equivalent (Ref https://web.archive.org/web/20090228203858/http://techxplorer.com/2006/07/18/converting-unicode-to-ascii-using-python):

   >>> teststr
   u'I don\xe2\x80\x98t like this'
   >>> unicodedata.normalize('NFKD', teststr).encode('ascii', 'ignore')
   'I donat like this'
   

A bit verbose, but it's the standard way of parsing and formatting dates in Java:

DateFormat formatter = new SimpleDateFormat("HH:mm:ss");
try {
  Date dt = formatter.parse("08:19:12");
  Calendar cal = Calendar.getInstance();
  cal.setTime(dt);
  int hour = cal.get(Calendar.HOUR);
  int minute = cal.get(Calendar.MINUTE);
  int second = cal.get(Calendar.SECOND);
} catch (ParseException e) {
  // This can happen if you are trying to parse an invalid date, e.g., 25:19:12.
  // Here, you should log the error and decide what to do next
  e.printStackTrace();
}

Using the idea of totem and zlangner, I have created a KnownTypeConverter that will be able to determine the most appropriate inheritor, while taking into account that json data may not have optional elements.

So, the service sends a JSON response that contains an array of documents (incoming and outgoing). Documents have both a common set of elements and different ones. In this case, the elements related to the outgoing documents are optional and may be absent.

In this regard, a base class Document was created that includes a common set of properties. Two inheritor classes are also created: - OutgoingDocument adds two optional elements "device_id" and "msg_id"; - IncomingDocument adds one mandatory element "sender_id";

The task was to create a converter that based on json data and information from KnownTypeAttribute will be able to determine the most appropriate class that allows you to save the largest amount of information received. It should also be taken into account that json data may not have optional elements. To reduce the number of comparisons of json elements and properties of data models, I decided not to take into account the properties of the base class and to correlate with json elements only the properties of the inheritor classes.

Data from the service:

{
    "documents": [
        {
            "document_id": "76b7be75-f4dc-44cd-90d2-0d1959922852",

}

        jObjectReader.SupportMultipleContent = reader.SupportMultipleContent;
        return jObjectReader;
    }
}

PS: In my case, if no one inheritor has not been selected by converter (this can happen if the JSON data contains information only from the base class or the JSON data does not contain optional elements from the OutgoingDocument), then an object of the OutgoingDocument class will be created, since it is listed first in the list of KnownTypeAttribute attributes. At your request, you can vary the implementation of the KnownTypeConverter in this situation.

What you can do to resolve your conflict is

svn resolve --accept working -R <path>

where <path> is where you have your conflict (can be the root of your repo).

Explanations:

• resolve asks svn to resolve the conflict
• accept working specifies to keep your working files
• -R stands for recursive

Hope this helps.

EDIT:

To sum up what was said in the comments below:

• <path> should be the directory in conflict (C:\DevBranch\ in the case of the OP)
• it's likely that the origin of the conflict is
  • either the use of the svn switch command
  • or having checked the Switch working copy to new branch/tag option at branch creation
• more information about conflicts can be found in the dedicated section of Tortoise's documentation.
• to be able to run the command, you should have the CLI tools installed together with Tortoise:

It would depend on the implementation, but the limit is not defined by the List interface.

The interface however defines the size() method, which returns an int.

Returns the number of elements in this list. If this list contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

So, no limit, but after you reach Integer.MAX_VALUE, the behaviour of the list changes a bit

ArrayList (which is tagged) is backed by an array, and is limited to the size of the array - i.e. Integer.MAX_VALUE

static final String[] keypad = {"", "", "ABC", "DEF", "GHI", "JKL", "MNO", "PQRS", "TUV", "WXYZ"};



String[] printAlphabet(int num){
        if (num >= 0 && num < 10){
            String[] retStr;
            if (num == 0 || num ==1){
                retStr = new String[]{""};
            } else {
                retStr = new String[keypad[num].length()];
                for (int i = 0 ; i < keypad[num].length(); i++){
                    retStr[i] = String.valueOf(keypad[num].charAt(i));
                }
            }
            return retStr;
        }

        String[] nxtStr = printAlphabet(num/10);

        int digit = num % 10;

        String[] curStr = null;
        if(digit == 0 || digit == 1){
            curStr = new String[]{""};
        } else {
            curStr = new String[keypad[digit].length()];
            for (int i = 0; i < keypad[digit].length(); i++){
                curStr[i] = String.valueOf(keypad[digit].charAt(i));
            }
        }

        String[] result = new String[curStr.length * nxtStr.length];
        int k=0;

        for (String cStr : curStr){
            for (String nStr : nxtStr){
                result[k++] = nStr + cStr;
            }
        }
        return result;
    }

However, the code below allows spaces.

No, it doesn't. However, it will only match on input with a length of 1. For inputs with a length greater than or equal to 1, you need a + following the character class:

var regexp = /^[a-zA-Z0-9-_]+$/;
var check = "checkme";
if (check.search(regexp) === -1)
    { alert('invalid'); }
else
    { alert('valid'); }

Note that neither the - (in this instance) nor the _ need escaping.

I found the above when looking for downloading from FTP with username and address in URL. Users supply information and then make the calls.

This was helpful because our organization has Kaspersky AV which blocks active FTP.exe, but not web connections. We were unable to develop in house with ftp.exe and this was our solution. Hope this helps other looking for info!

If you still have problems with Eclipse finding your files, you might try the following:

1. Verify that the file exists according to the current execution environment by using the java.io.File class to get a canonical path format and verify that (a) the file exists and (b) what the canonical path is.

2. Verify the default working directory by printing the following in your main:

       System.out.println("Working dir:  " + System.getProperty("user.dir"));
   

For (1) above, I put the following debugging code around the specific file I was trying to access:

            File imageFile = new File(source);
            System.out.println("Canonical path of target image: " + imageFile.getCanonicalPath());
            if (!imageFile.exists()) {
                System.out.println("file " + imageFile + " does not exist");
            }
            image = ImageIO.read(imageFile);                

For whatever reason, I ended up ignoring most of the other posts telling me to put the image files in "src" or some other variant, as I verified that the system was looking at the root of the Eclipse project directory hierarchy (e.g., $HOME/workspace/myProject).

Having the images in src/ (which is automatically copied to bin/) didn't do the trick on Eclipse Luna.

In this case, random is actually pseudo-random. Given a seed, it will generate numbers with an equal distribution. But with the same seed, it will generate the same number sequence every time. If you want it to change, you'll have to change your seed. A lot of people like to generate a seed based on the current time or something.

Any sort of console input works well with do-while because you prompt the first time, and re-prompt whenever the input validation fails.

As Christian's answer with assign() shows, there is a way to assign in the global environment. A simpler, shorter (but not better ... stick with assign) way is to use the <<- operator, ie

    a <<- "new" 

inside the function.

if permission issue and you have ssh access in root folder

find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;

will resolve your error

You can use position:absolute to position an overlay inside of your div and then stretch it in all directions like so:

CSS ^{updated *}

.overlay {
    position:absolute;
    top:0;
    left:0;
    right:0;
    bottom:0;
    background-color:rgba(0, 0, 0, 0.85);
    background: url(data:;base64,iVBORw0KGgoAAAANSUhEUgAAAAIAAAACCAYAAABytg0kAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAgY0hSTQAAeiYAAICEAAD6AAAAgOgAAHUwAADqYAAAOpgAABdwnLpRPAAAABl0RVh0U29mdHdhcmUAUGFpbnQuTkVUIHYzLjUuNUmK/OAAAAATSURBVBhXY2RgYNgHxGAAYuwDAA78AjwwRoQYAAAAAElFTkSuQmCC) repeat scroll transparent\9; /* ie fallback png background image */
    z-index:9999;
    color:white;
}

You just need to make sure that your parent div has the position:relative property added to it and a lower z-index.

Made a demo that should work in all browsers, including IE7+, for a commenter below.

Demo

Removed the opacity property from the css and instead used an rGBA color to give the background, and only the background, an opacity level. This way the content that the overlay carries will not be affected. Since IE does not support rGBA i used an IE hack instead to give it an base64 encoded PNG background image that fills the overlay div instead, this way we can evade IEs opacity issue where it applies the opacity to the children elements as well.

Go to the MinGW http sourceforge.net tree. Under Home/MinGW/Base/gcc/Version4(or whatever version use are using)/gcc-4(version)/ you'll find a file like gcc-core-4.8.1-4-mingw32-dll.tar.lzma. Extract it and go into the bin folder where you'll find your libgcc_s_dw2-1.dll and other dll's. Copy and paste what you need into your bin directory.

The clean, install and deploy phases are valid lifecycle phases and invoking them will trigger all the phases preceding them, and the goals bound to these phases.

mvn clean install

This command invokes the clean phase and then the install phase sequentially:

• clean: removes files generated at build-time in a project's directory (target by default)
• install: installs the package into the local repository, for use as a dependency in other projects locally.

mvn deploy

This command invokes the deploy phase:

• deploy: copies the final package to the remote repository for sharing with other developers and projects.

mvn release

This is not a valid phase nor a goal so this won't do anything. But if refers to the Maven Release Plugin that is used to automate release management. Releasing a project is done in two steps: prepare and perform. As documented:

Preparing a release goes through the following release phases:

• Check that there are no uncommitted changes in the sources
• Check that there are no SNAPSHOT dependencies
• Change the version in the POMs from x-SNAPSHOT to a new version (you will be prompted for the versions to use)
• Transform the SCM information in the POM to include the final destination of the tag
• Run the project tests against the modified POMs to confirm everything is in working order
• Commit the modified POMs
• Tag the code in the SCM with a version name (this will be prompted for)
• Bump the version in the POMs to a new value y-SNAPSHOT (these values will also be prompted for)
• Commit the modified POMs

And then:

Performing a release runs the following release phases:

• Checkout from an SCM URL with optional tag
• Run the predefined Maven goals to release the project (by default, deploy site-deploy)

OMG, I tried to find a simple solution to this for hours. I knew the code was simple but no one provided me what I wanted. So finally got to work on some example code and made something simple that anyone can use no JQuery required. Simple javascript and css and html. In order for the animation to work you have to set the height and width or the animation wont work. Found that out the hard way.

<script>
        function dostuff() {
            if (document.getElementById('MyBox').style.height == "0px") {

                document.getElementById('MyBox').setAttribute("style", "background-color: #45CEE0; height: 200px; width: 200px; transition: all 2s ease;"); 
            }
            else {
                document.getElementById('MyBox').setAttribute("style", "background-color: #45CEE0; height: 0px; width: 0px; transition: all 2s ease;"); 
             }
        }
    </script>
    <div id="MyBox" style="height: 0px; width: 0px;">
    </div>

    <input type="button" id="buttontest" onclick="dostuff()" value="Click Me">

I've found that the following works if you're not using jQuery and only interested in cloning simple objects (see comments).

JSON.parse(JSON.stringify(json_original));

You can do this entirely with html and css and i have.

HTML First you give the div you wish to hide an ID to target like #view_element and a class to target like #hide_element. You can if you wish make both of these classes but i don't know if you can make them both IDs. Then have your Show button target your show id and your Hide button target your hide class. That is it for the html the hiding and showing is done in the CSS.

CSS The css to show and hide this should look something like this

#hide_element:target {
    display:none;
}

.show_element:target{
    display:block;
}

This should allow you to hide and show elements at will. This should work nicely on spans and divs.

You have to run 'bibtex':

Third match in google for "C++ slicing" gives me this Wikipedia article http://en.wikipedia.org/wiki/Object_slicing and this (heated, but the first few posts define the problem) : http://bytes.com/forum/thread163565.html

So it's when you assign an object of a subclass to the super class. The superclass knows nothing of the additional information in the subclass, and hasn't got room to store it, so the additional information gets "sliced off".

If those links don't give enough info for a "good answer" please edit your question to let us know what more you're looking for.

The best solution I could find for this problem is to specify private key file in ansible.cfg (I usually keep it in the same folder as a playbook):

[defaults]
inventory=ec2.py
vault_password_file = ~/.vault_pass.txt
host_key_checking = False
private_key_file = /Users/eric/.ssh/secret_key_rsa

Though, it still sets private key globally for all hosts in playbook.

Note: You have to specify full path to the key file - ~user/.ssh/some_key_rsa silently ignored.

I run a large number of PHP daemons.

I agree with you that PHP is not the best (or even a good) language for doing this, but the daemons share code with the web-facing components so overall it is a good solution for us.

We use daemontools for this. It is smart, clean and reliable. In fact we use it for running all of our daemons.

You can check this out at http://cr.yp.to/daemontools.html.

EDIT: A quick list of features.

• Automatically starts the daemon on reboot
• Automatically restart dameon on failure
• Logging is handled for you, including rollover and pruning
• Management interface: 'svc' and 'svstat'
• UNIX friendly (not a plus for everyone perhaps)

For the Android library projects, I do it as in the attached screenshot:

Right click the project, select Properties->Android and in the library section click Add. From here you can select the available libraries.

If you are importing a jar file, then importing them as jar or external jar, as other posters posted would work. I prefer to copy/paste jar file in the libs folder (create one if it doesn't exist) and then import as jar.

To overwrite one file's content to another file. use cat eg.

echo  "this is foo" > foobar.txt
cat foobar.txt

echo "this is bar" > bar.txt
cat bar.txt

Now to overwrite foobar we can use a cat command as below

cat bar.txt >> foobar.txt
cat foobar.txt

1. Make an images folder inside src(/src/images) And keep your image in it. Then import this image in your component(use your relative path). Like below-

   import imageSrc from './images/image-name.jpg';

   And then in your component.

   <img title="my-img" src={imageSrc} alt="my-img" />

2. Another way is to keep images in public folder and import them using relative path. For this make an image folder in public folder and keep your image in it. And then in your component use it like below.

   <img title="my-img" src='/images/my-image.jpg' alt="my-img" />

   Both method work but first one is recommended because its cleaner way and images are handled by webpack during build time.

You're looking for axhline (a horizontal axis line). For example, the following will give you a horizontal line at y = 0.5:

import matplotlib.pyplot as plt
plt.axhline(y=0.5, color='r', linestyle='-')
plt.show()

Using this to push it to the remote upstream branch solved this issue for me:

git push <remote> master:origin/master

The remote had no access to the upstream repo so this was a good way to get the latest changes into that remote

In .Net, an assembly can be:

A collection of various manageable parts containing Types (or Classes), Resources (Bitmaps/Images/Strings/Files), Namespaces, Config Files compiled Privately or Publicly; deployed to a local or Shared (GAC) folder; discover-able by other programs/assemblies and; can be version-ed.

There's no way to do that in markdown's native features. However markdown allows inline HTML, so writing

      This will appear with six space characters in front of it

will produce:

      This will appear with six space characters in front of it

If you have control over CSS on the page, you could also use a tag and style it, either inline or with CSS rules.

Either way, markdown is not meant as a tool for layout, it is meant to simplify the process of writing for the web, so if you find yourself stretching its feature set to do what you need, you might look at whether or not you're using the right tool here. Check out Gruber's docs:

http://daringfireball.net/projects/markdown/syntax#html

use MouseDown, MouseMove and MouseUp. You can set a variable flag for that. I have a sample, but I think you need to revise.

I am coding the mouse action to a panel. Once you click the panel, your form will move with it.

//Global variables;
private bool _dragging = false;
private Point _offset;
private Point _start_point=new Point(0,0);


private void panel1_MouseDown(object sender, MouseEventArgs e)
{
   _dragging = true;  // _dragging is your variable flag
   _start_point = new Point(e.X, e.Y);
}

private void panel1_MouseUp(object sender, MouseEventArgs e)
{
   _dragging = false; 
}

private void panel1_MouseMove(object sender, MouseEventArgs e)
{
  if(_dragging)
  {
     Point p = PointToScreen(e.Location);
     Location = new Point(p.X - this._start_point.X,p.Y - this._start_point.Y);     
  }
}

Transmission Delay:

This is the amount of time required to transmit all of the packet's bits into the link. Transmission delays are typically on the order of microseconds or less in practice. 

L: packet length (bits)
R: link bandwidth (bps)
so transmission delay is = L/R

Propagation Delay:

Is the time it takes a bit to propagate over the transmission medium from the source router to the destination router; it is a function of the distance between the two routers, but has nothing to do with the packet's length or the transmission rate of the link. 

d: length of physical link
S: propagation speed in medium (~2x10⁸m/sec, for copper wires & ~3x10⁸m/sec, for wireless media)
so propagation delay is = d/s

setattr(x, attr, 'magic')

For help on it:

>>> help(setattr)
Help on built-in function setattr in module __builtin__:

setattr(...)
    setattr(object, name, value)

    Set a named attribute on an object; setattr(x, 'y', v) is equivalent to
    ``x.y = v''.

Edit: However, you should note (as pointed out in a comment) that you can't do that to a "pure" instance of object. But it is likely you have a simple subclass of object where it will work fine. I would strongly urge the O.P. to never make instances of object like that.

It is mentioned under "Index expressions".

An index expression on a map a of type map[K]V used in an assignment or initialization of the special form

v, ok = a[x] 
v, ok := a[x] 
var v, ok = a[x]

yields an additional untyped boolean value. The value of ok is true if the key x is present in the map, and false otherwise.

I happened to run with the same issue in iOS 7 (with some devices no simulators).

Looks like Safari in iOS 7 has a lower storage quota, which apparently is reached by having a long history log.

I guess the best practice will be to catch the exception.

The Modernizr project has an easy patch, you should try something similar: https://github.com/Modernizr/Modernizr/blob/master/feature-detects/storage/localstorage.js

Example: Display different output depending on whether the user is logged in or not.

<?php

if ( is_user_logged_in() ) {
    echo 'Welcome, registered user!';
} else {
    echo 'Welcome, visitor!';
}

?>

So you need a natural sort ?

If so, than maybe this script by Brian Huisman based on David koelle's work would be what you need.

It seems like Brian Huisman's solution is now directly hosted on David Koelle's blog:

• David koelle's article on the subject

I use in my batch files - c:\progra~2\ instead of C:\Program Files (x86)\ and it works.

The other answers are fine, but this is a little cleaner, in that it only gives the values like you would get from a DISTINCT query, without any cruft from Django.

>>> set(ProductOrder.objects.values_list('category', flat=True))
{u'category1', u'category2', u'category3', u'category4'}

or

>>> list(set(ProductOrder.objects.values_list('category', flat=True)))
[u'category1', u'category2', u'category3', u'category4']

And, it works without PostgreSQL.

This is less efficient than using a .distinct(), presuming that DISTINCT in your database is faster than a python set, but it's great for noodling around the shell.

Shouldn't you have:

DELETE FROM tableA WHERE entitynum IN (...your select...)

Now you just have a WHERE with no comparison:

DELETE FROM tableA WHERE (...your select...)

So your final query would look like this;

DELETE FROM tableA WHERE entitynum IN (
    SELECT tableA.entitynum FROM tableA q
      INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum) 
    WHERE (LENGTH(q.memotext) NOT IN (8,9,10) OR q.memotext NOT LIKE '%/%/%')
      AND (u.FldFormat = 'Date')
)

Update

Mongoose 5.7.1 was release and seems to fix the issue, so setting up the useUnifiedTopology option work as expected.

mongoose.connect(mongoConnectionString, {useNewUrlParser: true, useUnifiedTopology: true});

Original answer

I was facing the same issue and decided to deep dive on Mongoose code: https://github.com/Automattic/mongoose/search?q=useUnifiedTopology&unscoped_q=useUnifiedTopology

Seems to be an option added on version 5.7 of Mongoose and not well documented yet. I could not even find it mentioned in the library history https://github.com/Automattic/mongoose/blob/master/History.md

According to a comment in the code:

• @param {Boolean} [options.useUnifiedTopology=false] False by default. Set to true to opt in to the MongoDB driver's replica set and sharded cluster monitoring engine.

There is also an issue on the project GitHub about this error: https://github.com/Automattic/mongoose/issues/8156

In my case I don't use Mongoose in a replica set or sharded cluster and though the option should be false. But if false it complains the setting should be true. Once is true it still don't work, probably because my database does not run on a replica set or sharded cluster.

I've downgraded to 5.6.13 and my project is back working fine. So the only option I see for now is to downgrade it and wait for the fix to update for a newer version.

This is the minimum configuration that solves the problem.

use:

dependencies {
    ...
    implementation 'com.android.support:appcompat-v7:26.1.0'
    ...
}

with:

 compileSdkVersion 26
 buildToolsVersion "26.0.1"

and into the build.gradle file located inside the root of the proyect:

buildscript {
    ...
    ....
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        ...
        ...
    }
}

Since many browsers block popups by default and popups are really ugly, I recommend using lightbox or thickbox.

They are prettier and are not popups. They are extra HTML markups that are appended to your document's body with the appropriate CSS content.

If the record exists, it will be overwritten; if it does not yet exist, it will be created.

If you are trying to do something very similar: a is not None, the same issue comes up. That is, Numpy complains that one must use a.any or a.all.

A workaround is to do:

if not (a is None):
    pass

Not too pretty, but it does the job.

$myarray = array_values($myarray);

Windows provides QueryPerformanceCounter() function, and Unix has gettimeofday() Both functions can measure at least 1 micro-second difference.

I had a similar issue and I had to check "Build Active Architecture Only" on each of the Project configurations (Debug, Release and Deployment) and in the Build Settings of the Target.

I like to use properties in a class instead of methods, since they look more enum-like.

Here's a example for a Logger:

public class LogCategory
{
    private LogCategory(string value) { Value = value; }

    public string Value { get; set; }

    public static LogCategory Trace   { get { return new LogCategory("Trace"); } }
    public static LogCategory Debug   { get { return new LogCategory("Debug"); } }
    public static LogCategory Info    { get { return new LogCategory("Info"); } }
    public static LogCategory Warning { get { return new LogCategory("Warning"); } }
    public static LogCategory Error   { get { return new LogCategory("Error"); } }
}

Pass in type-safe string values as a parameter:

public static void Write(string message, LogCategory logCategory)
{
    var log = new LogEntry { Message = message };
    Logger.Write(log, logCategory.Value);
}

Usage:

Logger.Write("This is almost like an enum.", LogCategory.Info);

An instance variable would probably be the way to do what you want. You could make it static to persist the same value for the life of the program (or thread depending on your static memory model), or make it an ordinary instance var to control it over the life of an object instance. If that instance is a singleton, they'll behave the same way.

#if DEBUG
private /*static*/ bool s_bDoDebugOnlyCode = false;
#endif

void foo()
{   
  // ...
#if DEBUG
  if (s_bDoDebugOnlyCode)
  {
      // Code here gets executed only when compiled with the DEBUG constant, 
      // and when the person debugging manually sets the bool above to true.  
      // It then stays for the rest of the session until they set it to false.
  }
#endif
 // ...
}

Just to be complete, pragmas (preprocessor directives) are considered a bit of a kludge to use to control program flow. .NET has a built-in answer for half of this problem, using the "Conditional" attribute.

private /*static*/ bool doDebugOnlyCode = false; 
[Conditional("DEBUG")]
void foo()
{   
  // ...    
  if (doDebugOnlyCode)
  {
      // Code here gets executed only when compiled with the DEBUG constant, 
      // and when the person debugging manually sets the bool above to true.  
      // It then stays for the rest of the session until they set it to false.
  }    
  // ...
}

No pragmas, much cleaner. The downside is that Conditional can only be applied to methods, so you'll have to deal with a boolean variable that doesn't do anything in a release build. As the variable exists solely to be toggled from the VS execution host, and in a release build its value doesn't matter, it's pretty harmless.

I believe you are now able to use Window.getComputedStyle()

Documentation MDN

var style = window.getComputedStyle(element[, pseudoElt]);

Example to get width of an element:

window.getComputedStyle(document.querySelector('#mainbar')).width

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.

SQL doesn't return any ordering by default because it's faster this way. It doesn't have to go through your data first and then decide what to do.

You need to add an order by clause, and probably order by which ever ID you expect. (There's a duplicate of names, thus I'd assume you want One.ID)

select * From one
inner join two
ON one.one_name = two.one_name
ORDER BY one.ID

log4j2 has a very flexible configuration system (which IMHO is more a distraction than a help), you can even use JSON. See https://logging.apache.org/log4j/2.x/manual/configuration.html for a reference.

Personally, I just recently started using log4j2, but I'm tending toward the "strict XML" configuration (that is, using attributes instead of element names), which can be schema-validated.

Here is my simple example using autoconfiguration and strict mode, using a "Property" for setting the filename:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration monitorinterval="30" status="info" strict="true">
    <Properties>
        <Property name="filename">log/CelsiusConverter.log</Property>
    </Properties>
    <Appenders>
        <Appender type="Console" name="Console">
            <Layout type="PatternLayout" pattern="%d %p [%t] %m%n" />
        </Appender>
        <Appender type="Console" name="FLOW">
            <Layout type="PatternLayout" pattern="%C{1}.%M %m %ex%n" />
        </Appender>
        <Appender type="File" name="File" fileName="${filename}">
            <Layout type="PatternLayout" pattern="%d %p %C{1.} [%t] %m%n" />
        </Appender>
    </Appenders>
    <Loggers>
        <Root level="debug">
            <AppenderRef ref="File" />
            <AppenderRef ref="Console" />
            <!-- Use FLOW to trace down exact method sending the msg -->
            <!-- <AppenderRef ref="FLOW" /> -->
        </Root>
    </Loggers>
</Configuration>

Python 3

• class MyClass(object): = New-style class
• class MyClass: = New-style class (implicitly inherits from object)

Python 2

• class MyClass(object): = New-style class
• class MyClass: = OLD-STYLE CLASS

Explanation:

When defining base classes in Python 3.x, you’re allowed to drop the object from the definition. However, this can open the door for a seriously hard to track problem…

Python introduced new-style classes back in Python 2.2, and by now old-style classes are really quite old. Discussion of old-style classes is buried in the 2.x docs, and non-existent in the 3.x docs.

The problem is, the syntax for old-style classes in Python 2.x is the same as the alternative syntax for new-style classes in Python 3.x. Python 2.x is still very widely used (e.g. GAE, Web2Py), and any code (or coder) unwittingly bringing 3.x-style class definitions into 2.x code is going to end up with some seriously outdated base objects. And because old-style classes aren’t on anyone’s radar, they likely won’t know what hit them.

So just spell it out the long way and save some 2.x developer the tears.

Node is missing from the SYSTEM PATH, try this in your command line

SET PATH=C:\Program Files\Nodejs;%PATH%

and then try running node

To set this system wide you need to set in the system settings - cf - http://banagale.com/changing-your-system-path-in-windows-vista.htm

To be very clean, create a new system variable NODEJS

NODEJS="C:\Program Files\Nodejs"

Then edit the PATH in system variables and add %NODEJS%

I found that setting the file's Copy To Output Directory parameter to Copy Always seems to have cleared up the locking issue. Although now I have 2 copies of the files and need to delete one.

Try changing your workspace. I am not sure this is the exact solution . I did face the same issue for sometime untill i changed my workspace.

You can increase the limit as follows:

1. Stop IIS.
2. Locate the file %WinDir%\System32\Inetsrv\Metabase.xml
3. Modify the AspBufferingLimit value. The default value is 4194304, which is about 4 MB. Changing it to 20MB (20971520).
4. Restart IIS.

Form values in HTTP POSTs are sent in the request body, in the same format as the querystring.

For more information, see the spec.

Sometimes it is just easier to try something simple like this.

validateNumber(control: FormControl): { [s: string]: boolean } {

  //revised to reflect null as an acceptable value 
  if (control.value === null) return null;

  // check to see if the control value is no a number
  if (isNaN(control.value)) {
    return { 'NaN': true };
  }

  return null; 
}

Hope this helps.

updated as per comment, You need to to call the validator like this

number: new FormControl('',[this.validateNumber.bind(this)])

The bind(this) is necessary if you are putting the validator in the component which is how I do it.

step by step

given you have a textbox as following,

<asp:TextBox ID="TextBox13" runat="server" 
  onkeypress="return functionx(event)" >
</asp:TextBox>

you create a JavaScript function like this:

     <script type = "text/javascript">
         function functionx(evt) 
         {
            if (evt.charCode > 31 && (evt.charCode < 48 || evt.charCode > 57))
                  {
                    alert("Allow Only Numbers");
                    return false;
                  }
          }
     </script>

the first part of the if-statement excludes the ASCII control chars, the or statements exclued anything, that is not a number

Example without any XML

Put your image image_name.jpg into res/drawable/image_name.jpg and use:

import android.app.Activity;
import android.os.Bundle;
import android.widget.ImageView;

public class Main extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        final ImageView imageView = new ImageView(this);
        imageView.setImageResource(R.drawable.image_name);
        setContentView(imageView);
    }
}

Tested on Android 22.

round(number, 1)

This is another option:

     switch (true) {
         case (value > 100):
             //do stuff
             break;
         case (value <= 100)&&(value > 75):
             //do stuff
             break;
         case (value < 50):
            //do stuff
             break;
     }

Edit the code to be as follows:

// Upload file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "images/" . "myFile.txt" );

if( $moved ) {
  echo "Successfully uploaded";         
} else {
  echo "Not uploaded because of error #".$_FILES["file"]["error"];
}

It will give you one of the following error code values 1 to 8:

UPLOAD_ERR_INI_SIZE = Value: 1; The uploaded file exceeds the upload_max_filesize directive in php.ini.

UPLOAD_ERR_FORM_SIZE = Value: 2; The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.

UPLOAD_ERR_PARTIAL = Value: 3; The uploaded file was only partially uploaded.

UPLOAD_ERR_NO_FILE = Value: 4; No file was uploaded.

UPLOAD_ERR_NO_TMP_DIR = Value: 6; Missing a temporary folder. Introduced in PHP 5.0.3.

UPLOAD_ERR_CANT_WRITE = Value: 7; Failed to write file to disk. Introduced in PHP 5.1.0.

UPLOAD_ERR_EXTENSION = Value: 8; A PHP extension stopped the file upload. PHP does not provide a way to ascertain which extension caused the file upload to stop; examining the list of loaded extensions with phpinfo() may help.

You can call window.focus();

but moving or losing the focus is bound to interfere with anyone using the tab key to get around the page.

By default the grid view will take care, just pass empty data set.

I frequently use std::string to hold utf-8 characters without any problems at all. I heartily recommend doing this when interfacing with API's which use utf-8 as the native string type as well.

For example, I use utf-8 when interfacing my code with the Tcl interpreter.

The major caveat is the length of the std::string, is no longer the number of characters in the string.

COPY your table (Name, Latitude, Longitude) FROM 'C:\Temp\your file.csv' DELIMITERS ',' CSV HEADER;

Use c:\Temp\"Your File"\.

The cut command is designed for this exact situation. It will "cut" on any delimiter and then you can specify which chunks should be output.

For instance: echo "foo bar <foo> bla 1 2 3.4" | cut -d " " -f 6-7

Will result in output of: 2 3.4

-d sets the delimiter

-f selects the range of 'fields' to output, in this case, it's the 6th through 7th chunks of the original string. You can also specify the range as a list, such as 6,7.

You have no shell at /bin/sh? Have you tried docker run -it pensu/busybox /usr/bin/sh ?

I assume you want to make modal use as much screen space as possible on phones. I've made a plugin to fix this UX problem of Bootstrap modals on mobile phones, you can check it out here - https://github.com/keaukraine/bootstrap-fs-modal

All you will need to do is to apply modal-fullscreen class and it will act similar to native screens of iOS/Android.

If you want to store a python dict in redis, it is better to store it as json string.

import redis

r = redis.StrictRedis(host='localhost', port=6379, db=0)
mydict = { 'var1' : 5, 'var2' : 9, 'var3': [1, 5, 9] }
rval = json.dumps(mydict)
r.set('key1', rval)

While retrieving de-serialize it using json.loads

data = r.get('key1')
result = json.loads(data)
arr = result['var3']

What about types (eg.bytes) that are not serialized by json functions ?

You can write encoder/decoder functions for types that cannot be serialized by json functions. eg. writing base64/ascii encoder/decoder function for byte array.

If you want to see how the Java compiler does certain things, you don't want decompilation, you want disassembly. Decompilation involves transforming the bytecode into Java source, meaning that a lot of low level information is lost, and if you're wondering about compiler optimization, this is probably the very information you're interested in.

Anyway, I happen to have written an open source Java disassembler. Unlike Javap, this works even on highly pathological classes, so you can see what obfuscation tools are doing to your classes as well. It can also do decompilation, though I wouldn't recommend it.

This is horrifying. All these answers suggesting adding to the start of the label text, and there is not one word in the Java 11 (or earlier) documentation for JLabel to suggest that the text of a label is handled differently if it happens to start with <html>. Who says that works everywhere and always will? And you can get big, big surprises wrapping arbitrary text in and handing it to an html layout engine.

I've upvoted the answer that suggests JTextArea. But I'll note that JTextArea isn't a drop-in replacement; by default it expands to fill rows, which is not how JLabel acts. I haven't come up with a solution to that yet.

Here's the solution implementing the concept of Iteration:

def gcdIter(a, b):
    '''
    a, b: positive integers

    returns: a positive integer, the greatest common divisor of a & b.
    '''
    if a > b:
        result = b
    result = a

    if result == 1:
        return 1

    while result > 0:
        if a % result == 0 and b % result == 0:
            return result
        result -= 1

Try,

String className = this.getClass().getSimpleName();

This will work as long as you don't use it in a static method.

The problem is that you are returning the toString() of the call to Base64.encodeBase64(bytes) which returns a byte array. So what you get in the end is the default string representation of a byte array, which corresponds to the output you get.

Instead, you should do:

encodedfile = new String(Base64.encodeBase64(bytes), "UTF-8");

Per correct answer by fargth, follows is a small code sample that might help.

First, create a class that extends WebViewClient and which is set to ignore SSL errors:

// SSL Error Tolerant Web View Client
private class SSLTolerentWebViewClient extends WebViewClient {

            @Override
            public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
                handler.proceed(); // Ignore SSL certificate errors
            }

}

Then with your web view object (initiated in the OnCreate() method), set its web view client to be an instance of the override class:

 mWebView.setWebViewClient(
                new SSLTolerentWebViewClient()
        );

On a recent project we had the challenge of working with and manipulating a large collection of data. Our client provided us with a 50 CSV files ranging from 30 MB to 350 MB in size and all in all containing approximately 20 million rows of data and 15 columns of data. Our end goal was to import and manipulate the data into a MySQL relational database to be used to power a front-end PHP script that we also developed. Now, working with a dataset this large or larger is not the simplest of tasks and in working on it we wanted to take a moment to share some of the things you should consider and know when working with large datasets like this.

1. Analyze Your Dataset Pre-Import

   I can’t stress this first step enough! Make sure that you take the time to analyze the data you are working with before importing it at all. Getting an understand of what all of the data represents, what columns related to what and what type of manipulation you need to will end up saving you time in the long run.

2. LOAD DATA INFILE is Your Friend

   Importing large data files like the ones we worked with (and larger ones) can be tough to do if you go ahead and try a regular CSV insert via a tool like PHPMyAdmin. Not only will it fail in many cases because your server won’t be able to handle a file upload as large as some of your data files due to upload size restrictions and server timeouts, but even if it does succeed, the process could take hours depending our your hardware. The SQL function LOAD DATA INFILE was created to handle these large datasets and will significantly reduce the time it takes to handle the import process. Of note, this can be executed through PHPMyAdmin, but you may still have file upload issues. In that case you can upload the files manually to your server and then execute from PHPMyAdmin (see their manual for more info) or execute the command via your SSH console (assuming you have your own server)

   LOAD DATA INFILE '/mylargefile.csv' INTO TABLE temp_data FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n'
   

3. MYISAM vs InnoDB

   Large or small database it’s always good to take a little time to consider which database engine you are going to use for your project. The two main engines you are going to read about are MYISAM and InnoDB and each has their own benefits and drawbacks. In brief the things to consider (in general) are as follows:

   MYISAM

   • Lower Memory Usage
   • Allows for Full-Text Searching
   • Table Level Locking – Locks Entire Table on Write
   • Great for Read-Intensive Applications

   InnoDB

   • List item
   • Uses More Memory
   • No Full-Text Search Support
   • Faster Performance
   • Row Level Locking – Locks Single Row on Write
   • Great for Read/Write Intensive Applications

4. Plan Your Design Carefully

   MySQL AnalyzeYour databases design/structure is going to be a large factor in how it performs. Take your time when it comes to planning out the different fields and analyze the data to figure out what the best field types, defaults and field length. You want to accommodate for the right amounts of data and try to avoid varchar columns and overly large data types when the data doesn’t warrant it. As an additional step after you are done with your database, you make want to see what MySQL suggests as field types for all of your different fields. You can do this by executing the following SQL command:

   ANALYZE TABLE my_big_table
   

   The result will be a description of each columns information along with a recommendation for what type of datatype it should be along with a proper length. Now you don’t necessarily need to follow the recommendations as they are based solely on existing data, but it may help put you on the right track and get you thinking

5. To Index or Not to Index

   For a dataset as large as this it’s infinitely important to create proper indexes on your data based off of what you need to do with the data on the front-end, BUT if you plan to manipulate the data beforehand refrain from placing too many indexes on the data. Not only will it will make your SQL table larger, but it will also slow down certain operations like column additions, subtractions and additional indexing. With our dataset we needed to take the information we just imported and break it into several different tables to create a relational structure as well as take certain columns and split the information into additional columns. We placed an index on the bare minimum of columns that we knew would help us with the manipulation. All in all, we took 1 large table consisting of 20 million rows of data and split its information into 6 different tables with pieces of the main data in them along with newly created data based off the existing content. We did all of this by writing small PHP scripts to parse and move the data around.

6. Finding a Balance

   A big part of working with large databases from a programming perspective is speed and efficiency. Getting all of the data into your database is great, but if the script you write to access the data is slow, what’s the point? When working with large datasets it’s extremely important that you take the time to understand all of the queries that your script is performing and to create indexes to help those queries where possible. One such way to analyze what your queries are doing is by executing the following SQL command:

   EXPLAIN SELECT some_field FROM my_big_table WHERE another_field='MyCustomField';
   

   By adding EXPLAIN to the start of your query MySQL will spit out information describing what indexes it tried to use, did use and how it used them. I labeled this point ‘Finding a balance’ because although indexes can help your script perform faster, they can just as easily make it run slower. You need to make sure you index what is needed and only what is needed. Every index consumes disk space and adds to the overhead of the table. Every time you make an edit to your table, you have to rebuild the index for that particular row and the more indexes you have on those rows, the longer it will take. It all comes down to making smart indexes, efficient SQL queries and most importantly benchmarking as you go to understand what each of your queries is doing and how long it’s taking to do it.

7. Index On, Index Off

   As we worked on the database and front-end script, both the client and us started to notice little things that needed changing and that required us to make changes to the database. Some of these changes involved adding/removing columns and changing the column types. As we had already setup a number of indexes on the data, making any of these changes required the server to do some serious work to keep the indexes in place and handle any modifications. On our small VPS server, some of the changes were taking upwards of 6 hours to complete…certainly not helpful to us being able to do speedy development. The solution? Turn off indexes! Sometimes it’s better to turn the indexes off, make your changes and then turn the indexes back on….especially if you have a lot of different changes to make. With the indexes off, the changes took a matter of seconds to minutes versus hours. When we were happy with our changes we simply turned our indexes back on. This of course took quite some time to re-index everything, but it was at least able to re-index everything all at once, reducing the overall time needed to make these changes one by one. Here’s how to do it:

   • Disable Indexes: ALTER TABLE my_big_table DISABLE KEY
   • Enable Indexes: ALTER TABLE my_big_table ENABLE KEY

8. Give MySQL a Tune-Up

   Don’t neglect your server when it comes to making your database and script run quickly. Your hardware needs just as much attention and tuning as your database and script does. In particular it’s important to look at your MySQL configuration file to see what changes you can make to better enhance its performance. A great little tool that we’ve come across is the MySQL Tuner http://mysqltuner.com/ . It’s a quick little Perl script that you can download right to your server and run via SSH to see what changes you might want to make to your configuration. Note that you should actively use your front-end script and database for several days before running the tuner so that the tuner has data to analyze. Running it on a fresh server will only provide minimal information and tuning options. We found it great to use the tuner script every few days for the two weeks to see what recommendations it would come up with and at the end we had significantly increased the databases performance.

9. Don’t be Afraid to Ask

   Working with SQL can be challenging to begin with and working with extremely large datasets only makes it that much harder. Don’t be afraid to go to professionals who know what they are doing when it comes to large datasets. Ultimately you will end up with a superior product, quicker development and quicker front-end performance. When it comes to large databases sometimes it’s take a professionals experienced eyes to find all the little caveats that could be slowing your databases performance.

The best way to get good control over the colorbar position is to give it its own axis. Like so:

# What I imagine your plotting looks like so far
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(your_data)

# Now adding the colorbar
cbaxes = fig.add_axes([0.8, 0.1, 0.03, 0.8]) 
cb = plt.colorbar(ax1, cax = cbaxes)  

The numbers in the square brackets of add_axes refer to [left, bottom, width, height], where the coordinates are just fractions that go from 0 to 1 of the plotting area.

You can use .indexOf() and .substr() like this:

var val = $("input").val();
var myString = val.substr(val.indexOf("?") + 1)

You can test it out here. If you're sure of the format and there's only one question mark, you can just do this:

var myString = $("input").val().split("?").pop();

import re
regex = ur"\[P\] (.+?) \[/P\]+?"
line = "President [P] Barack Obama [/P] met Microsoft founder [P] Bill Gates [/P], yesterday."
person = re.findall(regex, line)
print(person)

yields

['Barack Obama', 'Bill Gates']

The regex ur"[\u005B1P\u005D.+?\u005B\u002FP\u005D]+?" is exactly the same unicode as u'[[1P].+?[/P]]+?' except harder to read.

The first bracketed group [[1P] tells re that any of the characters in the list ['[', '1', 'P'] should match, and similarly with the second bracketed group [/P]].That's not what you want at all. So,

• Remove the outer enclosing square brackets. (Also remove the stray 1 in front of P.)
• To protect the literal brackets in [P], escape the brackets with a backslash: \[P\].
• To return only the words inside the tags, place grouping parentheses around .+?.

Java has a Random class in the java.util package. Using it you can do the following:

Random rnd = new Random();
int randomNumberFromArray = array[rnd.nextInt(3)];

Hope this helps!

I realize there are a ton of solutions here, but I found none of them hit every requirement I had:

• No custom coding required
• Code works on page load
• No custom classes required (checkboxes or their parent)
• I needed several checkbox lists to share the same name for submitting Github issues via their API, and was using the name label[] to assign labels across many form fields (two checkbox lists and a few selects and textboxes) - granted I could have achieved this without them sharing the same name, but I decided to try it, and it worked.

The only requirement for this one is jQuery. You can combine this with @ewall's great solution to add custom validation error messages.

For that I wrote a bash script:

#set -x 
branchname=`git branch | grep -F '*' |  awk '{print $2}'`
echo $branchname
git fetch origin ${branchname}
for file in `git status | awk '{if ($1 == "modified:") print $2;}'`
do
echo "PLEASE CHECK OUT GIT DIFF FOR "$file 
git difftool  FETCH_HEAD $file ;
done

In the above script, I fetch the remote main branch (not necessary its master branch ANY branch) to FETCH_HEAD, then make a list of my modified file only and compare modified files to git difftool.

There are many difftool supported by git, I configured Meld Diff Viewer for good GUI comparison.
From the above script, I have prior knowledge what changes done by other teams in same file, before I follow git stages untrack-->staged-->commit which help me to avoid unnecessary resolve merge conflict with remote team or make new local branch and compare and merge on the main branch.

This means that somewhere else in your code, you have something like:

sum = 0

Which shadows the builtin sum (which is callable) with an int (which isn't).

As other posters have pointed out, there are some limitations with the AWS Transfer for SFTP service. You need to closely align requirements. For example, there are no quotas, whitelists/blacklists, file type limits, and non key based access requires external services. There is also a certain overhead relating to user management and IAM, which can get to be a pain at scale.

We have been running an SFTP S3 Proxy Gateway for about 5 years now for our customers. The core solution is wrapped in a collection of Docker services and deployed in whatever context is needed, even on-premise or local development servers. The use case for us is a little different as our solution is focused data processing and pipelines vs a file share. In a Salesforce example, a customer will use SFTP as the transport method sending email, purchase...data to an SFTP/S3 enpoint. This is mapped an object key on S3. Upon arrival, the data is picked up, processed, routed and loaded to a warehouse. We also have fairly significant auditing requirements for each transfer, something the Cloudwatch logs for AWS do not directly provide.

As other have mentioned, rolling your own is an option too. Using AWS Lightsail you can setup a cluster, say 4, of $10 2GB instances using either Route 53 or an ELB.

In general, it is great to see AWS offer this service and I expect it to mature over time. However, depending on your use case, alternative solutions may be a better fit.

just cut the string using split (the easy way):

var myString = "http://localhost/dms/mduserSecurity/UIL/index.php?menu=true&submenu=true&pcode=1235"
var mySplitResult = myString.split("?");
alert(mySplitResult[0]);

For Splashscreen you should use this line in manifest and don't use getActionBar()

<item name="android:windowActionBar">false</item>

and once when Splash Activity is finished in the main Activity use below or nothing

<item name="android:windowActionBar">true</item>

You can use isTRUE for such cases. isTRUE is the same as { is.logical(x) && length(x) == 1 && !is.na(x) && x }

If you use shiny there you could use isTruthy which covers the following cases:

• FALSE

• NULL

• ""

• An empty atomic vector

• An atomic vector that contains only missing values

• A logical vector that contains all FALSE or missing values

• An object of class "try-error"

• A value that represents an unclicked actionButton()

Don't write tests to get full coverage of your code. Write tests that guarantee your requirements. You may discover codepaths that are unnecessary. Conversely, if they are necessary, they are there to fulfill some kind of requirement; find it what it is and test the requirement (not the path).

Keep your tests small: one test per requirement.

Later, when you need to make a change (or write new code), try writing one test first. Just one. Then you'll have taken the first step in test-driven development.

Update April 2013: Don't do this. It wasn't a good idea in 2009 when I first answered the question and it really isn't a good idea now. See this answer by hackbod for reasons:

Avoid reloading activity with asynctask on orientation change in android

Add android:configChanges="keyboardHidden|orientation" to your AndroidManifest.xml. This tells the system what configuration changes you are going to handle yourself - in this case by doing nothing.

<activity android:name="MainActivity"
     android:screenOrientation="portrait"
     android:configChanges="keyboardHidden|orientation">

See Developer reference configChanges for more details.

However, your application can be interrupted at any time, e.g. by a phone call, so you really should add code to save the state of your application when it is paused.

Update: As of Android 3.2, you also need to add "screenSize":

<activity
    android:name="MainActivity"
    android:screenOrientation="portrait"
    android:configChanges="keyboardHidden|orientation|screenSize">

From Developer guide Handling the Configuration Change Yourself

Caution: Beginning with Android 3.2 (API level 13), the "screen size" also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), you must include the "screenSize" value in addition to the "orientation" value. That is, you must declare android:configChanges="orientation|screenSize". However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device).

You are actually getting the correct value out.

The way your x86 (compatible) processor stores data like this, is in Little Endian order, meaning that, the MSB is last in your output.

So, given your output:

10101010

the last two hex values 10 are the Most Significant Byte (2 hex digits = 1 byte = 8 bits (for (possibly unnecessary) clarification).

So, by reversing the memory storage order of the bytes, your value is actually: 01010101.

Hope that clears it up!

if you using react 16.8 you can use react Hooks... React Hooks are functions that let you “hook into” React state and lifecycle features from function components... docs

Adding a solution for people with multiple Java versions installed

We have a large codebase, most of which is in Java. The majority of what I work on is written in either Java 1.7 or 1.8. Since JAVA_HOME is static, I created aliases in my .bashrc for running Maven with different values:

alias mvn5="JAVA_HOME=/usr/local/java5 && mvn"
alias mvn6="JAVA_HOME=/usr/local/java6 && mvn"
alias mvn7="JAVA_HOME=/usr/local/java7 && mvn"
alias mvn8="JAVA_HOME=/usr/local/java8 && mvn"

This lets me run Maven from the command line on my development machine regardless of the JDK version used on the project.

Edit: A better solution is presented by the answer from Ondrej, which obviates remembering aliases.

SELECT DATEADD(month, DATEDIFF(month, 0, @mydate), 0) AS StartOfMonth

You need to set index=False in to_excel in order for it to not write the index column out, this semantic is followed in other Pandas IO tools, see http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.to_excel.html and http://pandas.pydata.org/pandas-docs/stable/io.html

No, there is no such construct in C#, but the .NET JIT compiler could decide to do inline function calls on JIT time. But i actually don't know if it is really doing such optimizations.
(I think it should :-))

Section 6.16 Frame target names in the HTML 4.01 spec defines the meanings, but it is partly outdated. It refers to “windows”, whereas HTML5 drafts more realistically speak about “browsing contexts”, since modern browsers often use tabs instead of windows in this context.

Briefly, _self is the default (current browsing context, i.e. current window or tab), so it is useful only to override a <base target=...> setting. The value _parent refers to the frameset that is the parent of the current frame, whereas _top “breaks out of all frames” and opens the linked document in the entire browser window.

Implicitly wait and Thread.sleep Both are used for synchronization only..but the difference is we can use Implicitly wait for entire program but Thread.sleep will works for that single code only..Here my suggestion is use Implicitly wait once in the program when every time your Webpage will get refreshed means use Thread.sleep at that time..it will much Better :)

Here is My Code :

package beckyOwnProjects;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.Actions;

public class Flip {

    public static void main(String[] args) throws InterruptedException {
        WebDriver driver=new FirefoxDriver();
        driver.manage().window().maximize();
        driver.manage().timeouts().implicitlyWait(2, TimeUnit.MINUTES);
        driver.get("https://www.flipkart.com");
    WebElement ele=driver.findElement(By.cssSelector(".menu-text.fk-inline-block"));
    Actions act=new Actions(driver);
    Thread.sleep(5000);
    act.moveToElement(ele).perform();
    }

}

If you install the application on your device via adb install you should look for the reinstall option which should be -r. So if you do adb install -r you should be able to install without uninstalling before.

My guess is it's not in your path.
in bash, try:
echo $PATH
and
sudo which nginx
And see if the folder containing nginx is also in your $PATH variable.
If not, either add the folder to your path environment variable, or create an alias (and put it in your .bashrc) ooor your could create a link i guess.
or sudo nginx -v if you just want that...

The usual way is to use zip():

for x, y in zip(a, b):
    # x is from a, y is from b

This will stop when the shorter of the two iterables a and b is exhausted. Also worth noting: itertools.izip() (Python 2 only) and itertools.izip_longest() (itertools.zip_longest() in Python 3).

No because this fundamentally means that you will not be grouping anything. If you group by all columns (and have a properly defined table w/ a unique index) then SELECT * FROM table is essentially the same thing as SELECT * FROM table GROUP BY *.

If you dont want to process response

private RestTemplate restTemplate = new RestTemplate();
restTemplate.postForObject(serviceURL, request, Void.class);

If you need response to process

String result = restTemplate.postForObject(url, entity, String.class);

Easy way to get the text inside of the editor or the length of it :)

 var editorText = CKEDITOR.instances['<%= your_editor.ClientID %>'].getData();
 alert(editorText);

 var editorTextLength = CKEDITOR.instances['<%= your_editor.ClientID %>'].getData().length;
 alert(editorTextLength);

Simple workaround I used just now while in a similar situation:

1. Make a duplicate of the worksheet.
2. Cut + Paste the cells with formulas from the duplicate worksheet (e.g. Copy of Sheet1) into the original worksheet.
3. Remove all occurrences of the the duplicate sheet's name from the newly pasted formulas; e.g. find-and-replace all occurrences of the search term 'Copy of Sheet1'! with an empty string (i.e. blank).
4. Delete duplicate worksheet to clean up.

Note: if your sheet name lacks spaces you won't need to use the single quote/apostrophe (').

Your cell references are now copied without being altered.

Download android SDK from developer.android.com (its currently a 149mb file for windows OS). It is worthy of note that android has removed the sdkmanager GUI but has a command line version of the sdkmanager in the bin folder which is located inside the tools folder.

1. When inside the bin folder, hold down the shift key, right click, then select open command line here. Shift+right click >> open command line here.
2. When the command line opens, type sdkmanager click enter.
3. Then run type sdkmanager (space), double hyphen (--), type list sdkmanager --list (this lists all the packages in the SDK manager)
4. Type sdkmanager (space) then package name, press enter. Eg. sdkmanager platform-tools (press enter) It will load licence agreement. With options (y/n). Enter y to accept and it will download the package you specified.

If anyone is looking into this, I've been trying different options and the following approach yields very good results. The following are the steps to get a working example:

1. Add .NET Wrapper for tesseract to your project. It can be added via NuGet package Install-Package Tesseract(https://github.com/charlesw/tesseract).
2. Go to the Downloads section of the official Tesseract project (https://code.google.com/p/tesseract-ocr/ EDIT: It's now located here: https://github.com/tesseract-ocr/langdata).
3. Download the preferred language data, example: tesseract-ocr-3.02.eng.tar.gz English language data for Tesseract 3.02.
4. Create tessdata directory in your project and place the language data files in it.
5. Go to Properties of the newly added files and set them to copy on build.
6. Add a reference to System.Drawing.
7. From .NET Wrapper repository, in the Samples directory copy the sample phototest.tif file into your project directory and set it to copy on build.
8. Create the following two files in your project (just to get started):

Program.cs

using System;
using Tesseract;
using System.Diagnostics;

namespace ConsoleApplication
{
    class Program
    {
        public static void Main(string[] args)
        {
            var testImagePath = "./phototest.tif";
            if (args.Length > 0)
            {
                testImagePath = args[0];
            }

            try
            {
                var logger = new FormattedConsoleLogger();
                var resultPrinter = new ResultPrinter(logger);
                using (var engine = new TesseractEngine(@"./tessdata", "eng", EngineMode.Default))
                {
                    using (var img = Pix.LoadFromFile(testImagePath))
                    {
                        using (logger.Begin("Process image"))
                        {
                            var i = 1;
                            using (var page = engine.Process(img))
                            {
                                var text = page.GetText();
                                logger.Log("Text: {0}", text);
                                logger.Log("Mean confidence: {0}", page.GetMeanConfidence());

                                using (var iter = page.GetIterator())
                                {
                                    iter.Begin();

                                        {
                                            using (logger.Begin("Line {0}", i))
                                            {

                                                    {
                                                        if (iter.IsAtBeginningOf(PageIteratorLevel.Block))

                                                        }
                                                        if (iter.IsAtBeginningOf(PageIteratorLevel.TextLine))

Thank you php-b-grader. I improved the code, it is not necessary to use window.open(), the target is already specified in the form.

// Create a form
var mapForm = document.createElement("form");
mapForm.target = "_blank";    
mapForm.method = "POST";
mapForm.action = "abmCatalogs.ftl";

// Create an input
var mapInput = document.createElement("input");
mapInput.type = "text";
mapInput.name = "variable";
mapInput.value = "lalalalala";

// Add the input to the form
mapForm.appendChild(mapInput);

// Add the form to dom
document.body.appendChild(mapForm);

// Just submit
mapForm.submit();

for target options --> w3schools - Target

If the input field has a class name formData use this : $(".formData").val("data")

If the input field has an id attribute name formData use this : $("#formData").val("data")

If the input name is given use this : $("input[name='formData']").val("data")

You can also mention the type. Then it will refer to all the inputs of that type and the given class name: $("input[type='text'].formData").val("data")

Try this

Sub Txt2Col()
    Dim rng As Range

    Set rng = [C7]
    Set rng = Range(rng, Cells(Rows.Count, rng.Column).End(xlUp))

    rng.TextToColumns Destination:=rng, DataType:=xlDelimited, ' rest of your settings

Update: button click event to act on another sheet

Private Sub CommandButton1_Click()
    Dim rng As Range
    Dim sh As Worksheet

    Set sh = Worksheets("Sheet2")
    With sh
        Set rng = .[C7]
        Set rng = .Range(rng, .Cells(.Rows.Count, rng.Column).End(xlUp))

        rng.TextToColumns Destination:=rng, DataType:=xlDelimited, _
        TextQualifier:=xlDoubleQuote,  _
        ConsecutiveDelimiter:=False, _
        Tab:=False, _
        Semicolon:=False, _
        Comma:=True, 
        Space:=False, 
        Other:=False, _
        FieldInfo:=Array(Array(1, xlGeneralFormat), Array(2, xlGeneralFormat), Array(3, xlGeneralFormat)), _
        TrailingMinusNumbers:=True
    End With
End Sub

Note the .'s (eg .Range) they refer to the With statement object

Starting with the 3.2 release of MongoDB, you can get N random docs from a collection using the $sample aggregation pipeline operator:

// Get one random document from the mycoll collection.
db.mycoll.aggregate([{ $sample: { size: 1 } }])

If you want to select the random document(s) from a filtered subset of the collection, prepend a $match stage to the pipeline:

// Get one random document matching {a: 10} from the mycoll collection.
db.mycoll.aggregate([
    { $match: { a: 10 } },
    { $sample: { size: 1 } }
])

As noted in the comments, when size is greater than 1, there may be duplicates in the returned document sample.

Language features:

Templates and Generic Code

• Template argument deduction for class templates

  • Like how functions deduce template arguments, now constructors can deduce the template arguments of the class
  • http://wg21.link/p0433r2 http://wg21.link/p0620r0 http://wg21.link/p0512r0

• template <auto>

  • Represents a value of any (non-type template argument) type.

• Non-type template arguments fixes

• template<template<class...>typename bob> struct foo {}

• ( Folding + ... + expressions ) and Revisions

• auto x{8}; is an int

• modernizing using with ... and lists

Lambda

• constexpr lambdas

  • Lambdas are implicitly constexpr if they qualify

• Capturing *this in lambdas

  • [*this]{ std::cout << could << " be " << useful << '\n'; }

Attributes

• [[fallthrough]], [[nodiscard]], [[maybe_unused]] attributes

• [[attributes]] on namespaces and enum { erator[[s]] }

• using in attributes to avoid having to repeat an attribute namespace.

• Compilers are now required to ignore non-standard attributes they don't recognize.

  • The C++14 wording allowed compilers to reject unknown scoped attributes.

Syntax cleanup

• Inline variables

  • Like inline functions
  • Compiler picks where the instance is instantiated
  • Deprecate static constexpr redeclaration, now implicitly inline.

• namespace A::B

• Simple static_assert(expression); with no string

• no throw unless throw(), and throw() is noexcept(true).

Cleaner multi-return and flow control

• Structured bindings

  • Basically, first-class std::tie with auto
  • Example:
    • const auto [it, inserted] = map.insert( {"foo", bar} );
    • Creates variables it and inserted with deduced type from the pair that map::insert returns.
  • Works with tuple/pair-likes & std::arrays and relatively flat structs
  • Actually named structured bindings in standard

• if (init; condition) and switch (init; condition)

  • if (const auto [it, inserted] = map.insert( {"foo", bar} ); inserted)
  • Extends the if(decl) to cases where decl isn't convertible-to-bool sensibly.

• Generalizing range-based for loops

  • Appears to be mostly support for sentinels, or end iterators that are not the same type as begin iterators, which helps with null-terminated loops and the like.

• if constexpr

  • Much requested feature to simplify almost-generic code.

Misc

• Hexadecimal float point literals

• Dynamic memory allocation for over-aligned data

• Guaranteed copy elision

  • Finally!
  • Not in all cases, but distinguishes syntax where you are "just creating something" that was called elision, from "genuine elision".

• Fixed order-of-evaluation for (some) expressions with some modifications

  • Not including function arguments, but function argument evaluation interleaving now banned
  • Makes a bunch of broken code work mostly, and makes .then on future work.

• Direct list-initialization of enums

• Forward progress guarantees (FPG) (also, FPGs for parallel algorithms)

  • I think this is saying "the implementation may not stall threads forever"?

• u8'U', u8'T', u8'F', u8'8' character literals (string already existed)

• "noexcept" in the type system

• __has_include

  • Test if a header file include would be an error
  • makes migrating from experimental to std almost seamless

• Arrays of pointer conversion fixes

• inherited constructors fixes to some corner cases (see P0136R0 for examples of behavior changes)

• aggregate initialization with inheritance.

• std::launder, type punning, etc

Library additions:

Data types

• std::variant<Ts...>

  • Almost-always non-empty last I checked?
  • Tagged union type
  • {awesome|useful}

• std::optional

  • Maybe holds one of something
  • Ridiculously useful

• std::any

  • Holds one of anything (that is copyable)

• std::string_view

  • std::string like reference-to-character-array or substring
  • Never take a string const& again. Also can make parsing a bajillion times faster.
  • "hello world"sv
  • constexpr char_traits

• std::byte off more than they could chew.

  • Neither an integer nor a character, just data

Invoke stuff

• std::invoke
  • Call any callable (function pointer, function, member pointer) with one syntax. From the standard INVOKE concept.
• std::apply
  • Takes a function-like and a tuple, and unpacks the tuple into the call.

• std::make_from_tuple, std::apply applied to object construction

• is_invocable, is_invocable_r, invoke_result

  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0077r2.html
  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0604r0.html
  • Deprecates result_of
  • is_invocable<Foo(Args...), R> is "can you call Foo with Args... and get something compatible with R", where R=void is default.
  • invoke_result<Foo, Args...> is std::result_of_t<Foo(Args...)> but apparently less confusing?

File System TS v1

• [class.path]

• [class.filesystem.error]

• [class.file_status]

• [class.directory_entry]

• [class.directory_iterator] and [class.recursive_directory_iterator]

  • Untimed, which can be more efficient if you don't need it.

• atomic<T>::is_always_lockfree

• scoped_lock<Mutexes...>

  • Saves some std::lock pain when locking more than one mutex at a time.

• Parallelism TS v1

  • The linked paper from 2014, may be out of date
  • Parallel versions of std algorithms, and related machinery

• hardware_*_interference_size

(parts of) Library Fundamentals TS v1 not covered above or below

• [func.searchers] and [alg.search]
  • A searching algorithm and techniques

• [pmr]

  • Polymorphic allocator, like std::function for allocators
  • And some standard memory resources to go with it.
  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0358r1.html

• std::sample, sampling from a range?

Container Improvements

• try_emplace and insert_or_assign

  • gives better guarantees in some cases where spurious move/copy would be bad

• Splicing for map<>, unordered_map<>, set<>, and unordered_set<>

  • Move nodes between containers cheaply.
  • Merge whole containers cheaply.

• non-const .data() for string.

• non-member std::size, std::empty, std::data

  • like std::begin/end

• Minimal incomplete type support in containers

• Contiguous iterator "concept"

• constexpr iterators

• The emplace family of functions now returns a reference to the created object.

Smart pointer changes

• unique_ptr<T[]> fixes and other unique_ptr tweaks.
• weak_from_this and some fixed to shared from this

Other std datatype improvements:

• {} construction of std::tuple and other improvements
• TriviallyCopyable reference_wrapper, can be performance boost

Misc

• C++17 library is based on C11 instead of C99

• Reserved std[0-9]+ for future standard libraries

• destroy(_at|_n), uninitialized_move(_n), uninitialized_value_construct(_n), uninitialized_default_construct(_n)

• std::not_fn
  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0358r1.html
• Rules for noexcept within std
• std::is_contiguous_layout, useful for efficient hashing
• std::to_chars/std::from_chars, high performance, locale agnostic number conversion; finally a way to serialize/deserialize to human readable formats (JSON & co)
• std::default_order, indirection over std::less. (breaks ABI of some compilers due to name mangling, removed.)

Traits

• swap
• is_aggregate
• has_unique_object_representations

Deprecated

• Some C libraries,
• <codecvt>
• memory_order_consume
• result_of, replaced with invoke_result
• shared_ptr::unique, it isn't very threadsafe

Isocpp.org has has an independent list of changes since C++14; it has been partly pillaged.

Naturally TS work continues in parallel, so there are some TS that are not-quite-ripe that will have to wait for the next iteration. The target for the next iteration is C++20 as previously planned, not C++19 as some rumors implied. C++1O has been avoided.

Initial list taken from this reddit post and this reddit post, with links added via googling or from the above isocpp.org page.

Additional entries pillaged from SD-6 feature-test list.

clang's feature list and library feature list are next to be pillaged. This doesn't seem to be reliable, as it is C++1z, not C++17.

these slides had some features missing elsewhere.

While "what was removed" was not asked, here is a short list of a few things ((mostly?) previous deprecated) that are removed in C++17 from C++:

Removed:

• register, keyword reserved for future use
• bool b; ++b;
• trigraphs
  • if you still need them, they are now part of your source file encoding, not part of language
• ios aliases
• auto_ptr, old <functional> stuff, random_shuffle
• allocators in std::function

There were rewordings. I am unsure if these have any impact on code, or if they are just cleanups in the standard:

Papers not yet integrated into above:

• P0505R0 (constexpr chrono)

• P0418R2 (atomic tweaks)

• P0512R0 (template argument deduction tweaks)

• P0490R0 (structured binding tweaks)

• P0513R0 (changes to std::hash)

• P0502R0 (parallel exceptions)

• P0509R1 (updating restrictions on exception handling)

• P0012R1 (make exception specifications be part of the type system)

• P0510R0 (restrictions on variants)

• P0504R0 (tags for optional/variant/any)

• P0497R0 (shared ptr tweaks)

• P0508R0 (structured bindings node handles)

• P0521R0 (shared pointer use count and unique changes?)

Spec changes:

• exception specs and throw expressions

Further reference:

• papers grouped by year; not all accepted

• https://isocpp.org/files/papers/p0636r0.html

  • Should be updated to "Modifications to existing features" here.

For those looking for a Swift version of @amro's answer:

    let userDefaults = NSUserDefaults.standardUserDefaults()

    if userDefaults.boolForKey("hasRunBefore") == false {

        // remove keychain items here


        // update the flag indicator
        userDefaults.setBool(true, forKey: "hasRunBefore")
        userDefaults.synchronize() // forces the app to update the NSUserDefaults

        return
    }

I would like to make a little bit more emphasis on some key differences between res.end() & res.send() with respect to response headers and why they are important.

1. res.send() will check the structure of your output and set header information accordingly.

    app.get('/',(req,res)=>{
       res.send('<b>hello</b>');
    });

     app.get('/',(req,res)=>{
         res.send({msg:'hello'});
     });

Where with res.end() you can only respond with text and it will not set "Content-Type"

      app.get('/',(req,res)=>{
           res.end('<b>hello</b>');
      }); 

2. res.send() will set "ETag" attribute in the response header

      app.get('/',(req,res)=>{
            res.send('<b>hello</b>');
      });

¿Why is this tag important?
The ETag HTTP response header is an identifier for a specific version of a resource. It allows caches to be more efficient, and saves bandwidth, as a web server does not need to send a full response if the content has not changed.

res.end() will NOT set this header attribute

It is called favicon.ico and you can generate it from this site.

I had this problem on android Studio because in my Debug build i've added version name suffix -DEBUG and the - was the problem.

Try to only have letters, numbers and dots on your version names and application ids

The lookup function returns an array of matching elements. You could check if the length is zero. Note the change to only look up the elements once and reuse the results as needed.

var elem = $("#btext" + i);
if (elem.length != 0) {
   elem.text("Branch " + i);
}

Also, have you tried just using the text function -- if no element exists, it will do nothing.

$("#btext" + i).text("Branch " + i);

(pathlib.Path('../../') ).resolve()

Using appendEncodePath() could save you multiple lines than appendPath(), the following code snippet builds up this url: http://api.openweathermap.org/data/2.5/forecast/daily?zip=94043

Uri.Builder urlBuilder = new Uri.Builder();
urlBuilder.scheme("http");
urlBuilder.authority("api.openweathermap.org");
urlBuilder.appendEncodedPath("data/2.5/forecast/daily");
urlBuilder.appendQueryParameter("zip", "94043,us");
URL url = new URL(urlBuilder.build().toString());

this error happens if you try access un-exists property

my guess is that sorting is done by spring by property name and not by real column name. and the error indicates that, in "UserBoard" there is no property named "boardId".

bests,

Because a null collection is not the same thing as an empty collection. An empty collection is a collection object with no elements; a null collection is a nonexistent object.

Here's something to try: Declare two collections of any sort. Initialize one normally so that it's empty, and assign the other the value null. Then try adding an object to both collections and see what happens.

I have changes from varchar to nvarchar, works for me.

What does it mean?

It means that you should not try to use the same iterator in two threads. If you have two threads that need to iterate over the keys, values or entries, then they each should create and use their own iterators.

What happens if I try to iterate the map with two threads at the same time?

It is not entirely clear what would happen if you broke this rule. You could just get confusing behavior, in the same way that you do if (for example) two threads try to read from standard input without synchronizing. You could also get non-thread-safe behavior.

But if the two threads used different iterators, you should be fine.

What happens if I put or remove a value from the map while iterating it?

That's a separate issue, but the javadoc section that you quoted adequately answers it. Basically, the iterators are thread-safe, but it is not defined whether you will see the effects of any concurrent insertions, updates or deletions reflected in the sequence of objects returned by the iterator. In practice, it probably depends on where in the map the updates occur.

After python 3.6, you can use formatted string literal. It's neat! (https://docs.python.org/3/whatsnew/3.6.html#whatsnew36-pep498)

try
 ...
except Exception as e:
    logger.error(f"Failed to upload to ftp: {e}")

Multiple right answers were presented, but there are still more methods: Class.isAssignableFrom() and simply attempting to cast the object (which might throw a ClassCastException).

Possible ways summarized

Let's summarize the possible ways to test if an object obj is an instance of type C:

// Method #1
if (obj instanceof C)
    ;

// Method #2
if (C.class.isInstance(obj))
    ;

// Method #3
if (C.class.isAssignableFrom(obj.getClass()))
    ;

// Method #4
try {
    C c = (C) obj;
    // No exception: obj is of type C or IT MIGHT BE NULL!
} catch (ClassCastException e) {
}

// Method #5
try {
    C c = C.class.cast(obj);
    // No exception: obj is of type C or IT MIGHT BE NULL!
} catch (ClassCastException e) {
}

Differences in null handling

There is a difference in null handling though:

• In the first 2 methods expressions evaluate to false if obj is null (null is not instance of anything).
• The 3rd method would throw a NullPointerException obviously.
• The 4th and 5th methods on the contrary accept null because null can be cast to any type!

To remember: null is not an instance of any type but it can be cast to any type.

Notes

• Class.getName() should not be used to perform an "is-instance-of" test becase if the object is not of type C but a subclass of it, it may have a completely different name and package (therefore class names will obviously not match) but it is still of type C.
• For the same inheritance reason Class.isAssignableFrom() is not symmetric:
  obj.getClass().isAssignableFrom(C.class) would return false if the type of obj is a subclass of C.

I'm just going to do this

def function():
  while True:
    #code here

    break

Use "break" to stop the function.

The message from Linus Torvalds may answer your question:

Modify/edit old commit messages

Short answer: you can not (if pushed).

extract (Linus refers to BitKeeper as BK):

Side note, just out of historical interest: in BK you could.

And if you're used to it (like I was) it was really quite practical. I would apply a patch-bomb from Andrew, notice something was wrong, and just edit it before pushing it out.

I could have done the same with git. It would have been easy enough to make just the commit message not be part of the name, and still guarantee that the history was untouched, and allow the "fix up comments later" thing.

But I didn't.

Part of it is purely "internal consistency". Git is simply a cleaner system thanks to everything being SHA1-protected, and all objects being treated the same, regardless of object type. Yeah, there are four different kinds of objects, and they are all really different, and they can't be used in the same way, but at the same time, even if their encoding might be different on disk, conceptually they all work exactly the same.

But internal consistency isn't really an excuse for being inflexible, and clearly it would be very flexible if we could just fix up mistakes after they happen. So that's not a really strong argument.

The real reason git doesn't allow you to change the commit message ends up being very simple: that way, you can trust the messages. If you allowed people to change them afterwards, the messages are inherently not very trustworthy.

To be complete, you could rewrite your local commit history in order to reflect what you want, as suggested by sykora (with some rebase and reset --hard, gasp!)

However, once you publish your revised history again (with a git push origin +master:master, the + sign forcing the push to occur, even if it doesn't result in a "fast-forward" commit)... you might get into some trouble.

Extract from this other SO question:

I actually once pushed with --force to git.git repository and got scolded by Linus BIG TIME. It will create a lot of problems for other people. A simple answer is "don't do it".

You can move Application.java to a folder under the java.

In order to create a File from a HTTP URL you need to download the contents from that URL:

URL url = new URL("http://www.google.ro/logos/2011/twain11-hp-bg.jpg");
URLConnection connection = url.openConnection();
InputStream in = connection.getInputStream();
FileOutputStream fos = new FileOutputStream(new File("downloaded.jpg"));
byte[] buf = new byte[512];
while (true) {
    int len = in.read(buf);
    if (len == -1) {
        break;
    }
    fos.write(buf, 0, len);
}
in.close();
fos.flush();
fos.close();

The downloaded file will be found at the root of your project: {project}/downloaded.jpg

With numpy :

im = Image.open('image.gif')
im_matrix = np.array(im)
print(im_matrix[0][0])

Give RGB vector of the pixel in position (0,0)

In case you use a different database schemas than ".dbo" or your db is containing Pk´s, which are composed by several fields, please don´t use the the solution of Carter Medlin, otherwise you will damage your db!!!

When you are working with different schemas try this (don´t forget to make a backup of your database before!):

DECLARE @sql AS NVARCHAR(max)=''
select @sql = @sql +
    'ALTER INDEX ALL ON ' + SCHEMA_NAME( t.schema_id) +'.'+ '['+ t.[name] + '] DISABLE;'+CHAR(13)
from  
    sys.tables t
where type='u'

select @sql = @sql +
    'ALTER INDEX ' + i.[name] + ' ON ' + SCHEMA_NAME( t.schema_id) +'.'+'[' + t.[name] + '] REBUILD;'+CHAR(13)
from  
    sys.key_constraints i
join
    sys.tables t on i.parent_object_id=t.object_id
where     i.type='PK'

exec dbo.sp_executesql @sql;
go

After doing some Fk-free actions, you can switch back with

DECLARE @sql AS NVARCHAR(max)=''
select @sql = @sql +
    'ALTER INDEX ALL ON ' + SCHEMA_NAME( t.schema_id) +'.'+'[' +  t.[name] + '] REBUILD;'+CHAR(13)
from  
    sys.tables t
where type='u'
print @sql

exec dbo.sp_executesql @sql;
exec sp_msforeachtable "ALTER TABLE ? WITH NOCHECK CHECK CONSTRAINT ALL";

It is completely fine to leave memory unfreed when you exit; malloc() allocates the memory from the memory area called "the heap", and the complete heap of a process is freed when the process exits.

That being said, one reason why people still insist that it is good to free everything before exiting is that memory debuggers (e.g. valgrind on Linux) detect the unfreed blocks as memory leaks, and if you have also "real" memory leaks, it becomes more difficult to spot them if you also get "fake" results at the end.

To remove the ", " part which is immediately followed by end of string, you can do:

str = str.replaceAll(", $", "");

This handles the empty list (empty string) gracefully, as opposed to lastIndexOf / substring solutions which requires special treatment of such case.

Example code:

String str = "kushalhs, mayurvm, narendrabz, ";
str = str.replaceAll(", $", "");
System.out.println(str);  // prints "kushalhs, mayurvm, narendrabz"

NOTE: Since there has been some comments and suggested edits about the ", $" part: The expression should match the trailing part that you want to remove.

• If your input looks like "a,b,c,", use ",$".
• If your input looks like "a, b, c, ", use ", $".
• If your input looks like "a , b , c , ", use " , $".

I think you get the point.

just insert class navbar-dark or navbar-light in the nav element:

<nav class="navbar navbar-dark navbar-expand-md">
    <button class="navbar-toggler">
        <span class="navbar-toggler-icon"></span>
    </button>
</nav>

If you have intl extension installed, you can use Transliterator::transliterate function to create a slug easily.

<?php
$string = 'Namnet på bildtävlingen';
$slug = \Transliterator::createFromRules(
    ':: Any-Latin;'
    . ':: NFD;'
    . ':: [:Nonspacing Mark:] Remove;'
    . ':: NFC;'
    . ':: [:Punctuation:] Remove;'
    . ':: Lower();'
    . '[:Separator:] > \'-\''
)
    ->transliterate( $string );
echo $slug; // namnet-pa-bildtavlingen
?>

JSON is perfectly capable of expressing lists of integers, and the JSON you have posted is valid. You can simply separate the integers by commas:

{
    "Id": "610",
    "Name": "15",
    "Description": "1.99",
    "ItemModList": [42, 47, 139]
}

What about using extension method?

public static class StringExtensions
{
   public static string Repeat(this char chatToRepeat, int repeat) {

       return new string(chatToRepeat,repeat);
   }
   public  static string Repeat(this string stringToRepeat,int repeat)
   {
       var builder = new StringBuilder(repeat*stringToRepeat.Length);
       for (int i = 0; i < repeat; i++) {
           builder.Append(stringToRepeat);
       }
       return builder.ToString();
   }
}

You could then write :

Debug.WriteLine('-'.Repeat(100)); // For Chars  
Debug.WriteLine("Hello".Repeat(100)); // For Strings

Note that a performance test of using the stringbuilder version for simple characters instead of strings gives you a major preformance penality : on my computer the difference in mesured performance is 1:20 between: Debug.WriteLine('-'.Repeat(1000000)) //char version and
Debug.WriteLine("-".Repeat(1000000)) //string version

Try this one:

 $ find . -name "*.txt" -type f -print | xargs file | grep "foo=" | cut -d: -f1

I'd like to add that inline functions are crucial when you are building shared library. Without marking function inline, it will be exported into the library in the binary form. It will be also present in the symbols table, if exported. On the other side, inlined functions are not exported, neither to the library binaries nor to the symbols table.

It may be critical when library is intended to be loaded at runtime. It may also hit binary-compatible-aware libraries. In such cases don't use inline.

We use groovy job file:

description('')
steps {
    environmentVariables {
        envs(PUPPETEER_SKIP_CHROMIUM_DOWNLOAD: true)
    }
}

Here is a one line lambda that also works:

df["TrueFalse"] = df['col1'].apply(lambda x: 1 if any(i in x for i in searchfor) else 0)

Input:

searchfor = ['og', 'at']

df = pd.DataFrame([('cat', 1000.0), ('hat', 2000000.0), ('dog', 1000.0), ('fog', 330000.0),('pet', 330000.0)], columns=['col1', 'col2'])

   col1  col2
0   cat 1000.0
1   hat 2000000.0
2   dog 1000.0
3   fog 330000.0
4   pet 330000.0

Apply Lambda:

df["TrueFalse"] = df['col1'].apply(lambda x: 1 if any(i in x for i in searchfor) else 0)

Output:

    col1    col2        TrueFalse
0   cat     1000.0      1
1   hat     2000000.0   1
2   dog     1000.0      1
3   fog     330000.0    1
4   pet     330000.0    0

int day = (int)DateTime.Now.DayOfWeek;

First day of the week: Sunday (with a value of zero)

If logical test is against a single column then you could use something like

USE AdventureWorks2012;  
GO  
SELECT   ProductNumber, Category =  
      CASE ProductLine  
         WHEN 'R' THEN 'Road'  
         WHEN 'M' THEN 'Mountain'  
         WHEN 'T' THEN 'Touring'  
         WHEN 'S' THEN 'Other sale items'  
         ELSE 'Not for sale'  
      END,  
   Name  
FROM Production.Product  
ORDER BY ProductNumber;  
GO

Here is the contents of the configuration file I used to support both .NET 2.0 and .NET 4 assemblies:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <!-- http://msdn.microsoft.com/en-us/library/w4atty68.aspx -->
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" />
    <supportedRuntime version="v2.0.50727" />
  </startup>
</configuration>

Also, here’s a simplified version of the PowerShell 1.0 compatible code I used to execute our scripts from the passed in command line arguments:

class Program {
  static void Main( string[] args ) {
    Console.WriteLine( ".NET " + Environment.Version );

    string script = "& " + string.Join( " ", args );
    Console.WriteLine( script );
    Console.WriteLine( );

    // Simple host that sends output to System.Console
    PSHost host = new ConsoleHost( this );
    Runspace runspace = RunspaceFactory.CreateRunspace( host );

    Pipeline pipeline = runspace.CreatePipeline( );
    pipeline.Commands.AddScript( script );

    try {
      runspace.Open( );
      IEnumerable<PSObject> output = pipeline.Invoke( );
      runspace.Close( );

      // ...
    }
    catch( RuntimeException ex ) {
      string psLine = ex.ErrorRecord.InvocationInfo.PositionMessage;
      Console.WriteLine( "error : {0}: {1}{2}", ex.GetType( ), ex.Message, psLine );
      ExitCode = -1;
    }
  }
}

In addition to the basic error handling shown above, we also inject a trap statement into the script to display additional diagnostic information (similar to Jeffrey Snover's Resolve-Error function).

I was thinking the error is due to "s3:ListObjects" action but I had to add the action "s3:ListBucket" to solve the issue "AccessDenied for ListObjects for S3 bucket"

In the first case you are declaring "int a" as a local variable(as declared inside a method) and local varible do not get default value.

But instance variable are given default value both for static and non-static.

Default value for instance variable:

int = 0

float,double = 0.0

reference variable = null

char = 0 (space character)

boolean = false

well there is a way to do it a little more code but really effective

$sql = "SELECT * FROM messages";  //your query_x000D_
$result=$connvar->query($sql);    //$connvar is the connection variable_x000D_
$flag=0;_x000D_
     while($rows2=mysqli_fetch_assoc($result2))_x000D_
    { $flag++;}_x000D_
    _x000D_
if($flag==0){no rows selected;}_x000D_
else{_x000D_
echo $flag." "."rows are selected"_x000D_
}

This is now trivial in tidyr with replace_na(). The function appears to work for data.tables as well as data.frames:

tidyr::replace_na(x, list(a=0, b=0))

you can try this exapmple

 START TRANSACTION;
 SET foreign_key_checks = 0;
 ALTER TABLE `job_definers` ADD CONSTRAINT `job_cities_foreign` FOREIGN KEY 
 (`job_cities`) REFERENCES `drop_down_lists`(`id`) ON DELETE CASCADE ON UPDATE CASCADE;
 SET foreign_key_checks = 1;
 COMMIT;

Note : if you are using phpmyadmin just uncheck Enable foreign key checks

as example

hope this soloution fix your problem :)

Try adding JSON.stringify(result) to convert the JS Object into a JSON string.

From your code I can see you are logging the result in error which is called if the AJAX request fails, so I'm not sure how you'd go about accessing the id/name/etc. then (you are checking for success inside the error condition!).

Note that if you use Chrome's console you should be able to browse through the object without having to stringify the JSON, which makes it easier to debug.

With help from the accepted answer here and the accepted answer above, I have used:

$ sed 's/^ *//; s/ *$//; /^$/d; /^\s*$/d' file.txt > output.txt

`s/^ *//`  => left trim
`s/ *$//`  => right trim
`/^$/d`    => remove empty line
`/^\s*$/d` => delete lines which may contain white space

This covers all the bases and works perfectly for my needs. Kudos to the original posters @Kent and @kev

I had actually done this from Django a while back. Open up a legitimate GMail account & enter the credentials here. Here's my code -

from email import Encoders
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.MIMEMultipart import MIMEMultipart

def sendmail(to, subject, text, attach=[], mtype='html'):
    ok = True
    gmail_user = settings.EMAIL_HOST_USER
    gmail_pwd  = settings.EMAIL_HOST_PASSWORD

    msg = MIMEMultipart('alternative')

    msg['From']    = gmail_user
    msg['To']      = to
    msg['Cc']      = '[email protected]'
    msg['Subject'] = subject

    msg.attach(MIMEText(text, mtype))

    for a in attach:
        part = MIMEBase('application', 'octet-stream')
        part.set_payload(open(attach, 'rb').read())
        Encoders.encode_base64(part)
        part.add_header('Content-Disposition','attachment; filename="%s"' % os.path.basename(a))
        msg.attach(part)

    try:
        mailServer = smtplib.SMTP("smtp.gmail.com", 687)
        mailServer.ehlo()
        mailServer.starttls()
        mailServer.ehlo()
        mailServer.login(gmail_user, gmail_pwd)
        mailServer.sendmail(gmail_user, [to,msg['Cc']], msg.as_string())
        mailServer.close()
    except:
        ok = False
    return ok

exec sp_helptext 'your_sp_name' -- don't forget the quotes

In management studio by default results come in grid view. If you would like to see it in text view go to:

Query --> Results to --> Results to Text

or CTRL + T and then Execute.

You can also try and use the caching built into ASP MVC:

Add the following attribute to the controller method you'd like to cache:

[OutputCache(Duration=10)]

In this case the ActionResult of this will be cached for 10 seconds.

More on this here

In situations where the class under test can be modified and when it's desirable to avoid byte code manipulation, to keep things fast or to minimise third party dependencies, here is my take on the use of a factory to extract the new operation.

public class TestedClass {

    interface PojoFactory { Pojo getNewPojo(); }

    private final PojoFactory factory;

    /** For use in production - nothing needs to change. */
    public TestedClass() {
        this.factory = new PojoFactory() {
            @Override
            public Pojo getNewPojo() {
                return new Pojo();
            }
        };
    }

    /** For use in testing - provide a pojo factory. */
    public TestedClass(PojoFactory factory) {
        this.factory = factory;
    }

    public void doSomething() {
        Pojo pojo = this.factory.getNewPojo();
        anythingCouldHappen(pojo);
    }
}

With this in place, your testing, asserts and verify calls on the Pojo object are easy:

public  void testSomething() {
    Pojo testPojo = new Pojo();
    TestedClass target = new TestedClass(new TestedClass.PojoFactory() {
                @Override
                public Pojo getNewPojo() {
                    return testPojo;
                }
            });
    target.doSomething();
    assertThat(testPojo.isLifeStillBeautiful(), is(true));
}

The only downside to this approach potentially arises if TestClass has multiple constructors which you'd have to duplicate with the extra parameter.

For SOLID reasons you'd probably want to put the PojoFactory interface onto the Pojo class instead, and the production factory as well.

public class Pojo {

    interface PojoFactory { Pojo getNewPojo(); }

    public static final PojoFactory productionFactory = 
        new PojoFactory() {
            @Override 
            public Pojo getNewPojo() {
                return new Pojo();
            }
        };
