this may be old, but for those looking for answer you can use this...

public void stopHandler() {
   handler.removeMessages(0);
}

cheers

Please check the below its working on my side in below code your handler will run after every 1 Second when you are on same activity

 HandlerThread handlerThread = new HandlerThread("HandlerThread");
                handlerThread.start();
                handler = new Handler(handlerThread.getLooper());
                runnable = new Runnable()
                {
                    @Override
                    public void run()
                    {

                            handler.postDelayed(this, 1000);
                        }
                };
                handler.postDelayed(runnable, 1000);

Another way is to handle the Runnable itself:

Runnable r = new Runnable {
    public void run() {
        if (booleanCancelMember != false) {
            //do what you need
        }
    }
}

There is another way of doing this with just JavaScript. All you have to do is toggle the visibility based on the current state of the DIV's visibility in CSS.

Example:

function toggleVideo() {
     var e = document.getElementById('video-over');

     if(e.style.visibility == 'visible') {
          e.style.visibility = 'hidden';
     } else if(e.style.visibility == 'hidden') {
          e.style.visibility = 'visible';
     }
}

What helped me to resolve this issue:

I have had another branch, have switched to that branch and built the project with mvn clean install. Everything was ok, then switched back to the master and build the project again and the errors disappeared. Invalidate caches and restart didn't help me.

Based on posted answered, this worked for me:

/* check for iOS 6 or 7 */
if ([[self navigationController].navigationBar respondsToSelector:@selector(setBarTintColor:)]) {
    [[self navigationController].navigationBar setBarTintColor:[UIColor whiteColor]];

} else {
    /* Set background and foreground */
    [[self navigationController].navigationBar setTintColor:[UIColor whiteColor]];
    [self navigationController].navigationBar.titleTextAttributes = [[NSDictionary alloc] initWithObjectsAndKeys:[UIColor blackColor],UITextAttributeTextColor,nil];
}

The solution that worked for me is as follows:

1. Make sure VirtualBox Manager is not running.
2. Back up the files ~\.VirtualBox\VirtualBox.xml and ~\.VirtualBox\VirtualBox.xml-prev.
3. Edit these files to modify the <HardDisks>...</HardDisks> section to remove the duplicate entry of <HardDisk />.
4. Now run VirtualBox Manager.

Example:

  <HardDisks>
    <HardDisk uuid="{38f266bd-0959-4caf-a0de-27ac9d52e3663}" location="~/VirtualBox VMs/VM1/box-disk001.vmdk" format="VMDK" type="Normal"/>
    <HardDisk uuid="{a6708d79-7393-4d96-89da-2539f75c5465e}" location="~/VirtualBox VMs/VM2/box-disk001.vmdk" format="VMDK" type="Normal"/>
    <HardDisk uuid="{bdce5d4e-9a1c-4f57-acfd-e2acfc8920552}" location="~/VirtualBox VMs/VM2/box-disk001.vmdk" format="VMDK" type="Normal"/>
  </HardDisks>

Note in the above fragment that the last two entries refer to the same VM but have different uuid's. One of them is invalid and should be removed. Which one is invalid can be found out by hit and trial -- first remove the second entry and try; if it doesn't work, remove the third entry.

This worked for me (on Windows 10):

1. Add the following lines into your scripts in the package.json file:

   "dev": "npm run development",
   "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
   "watch": "npm run development -- --watch",
   "watch-poll": "npm run watch -- --watch-poll",
   "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
   "prod": "npm run production",
   "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
   

2. Make your devDependencies looks something like this:

   "devDependencies": {
       "axios": "^0.18",
       "bootstrap": "^4.0.0",
       "popper.js": "^1.12",
       "cross-env": "^5.1",
       "jquery": "^3.2",
       "laravel-mix": "^2.0",
       "lodash": "^4.17.4",
       "vue": "^2.5.7"
   }
   

3. Remove node_modules folder

4. Run npm install
5. Run npm run dev

create a batch-file with the following code:

dir %1 /b /a-d > list.txt

Then drag & drop a directory on it and the files inside the directory will be listed in list.txt

No, it is not possible to seed Math.random(), but it's fairly easy to write your own generator, or better yet, use an existing one.

Check out: this related question.

Also, see David Bau's blog for more information on seeding.

Convert hashmap to a ArrayList with a pair class

Hashmap<Object,Object> items = new HashMap<>();

to

List<Pair<Object,Object>> items = new ArrayList<>();

so you can sort it as you want, or list sorted by adding order.

In general, when you get an error like this, just do

yum provides ld-linux.so.2

then you'll see something like:

glibc-2.20-5.fc21.i686 : The GNU libc libraries
Repo        : fedora
Matched from:
Provides    : ld-linux.so.2

and then you just run the following like BRPocock wrote (in case you were wondering what the logic was...):

yum install glibc.i686

For what it's worth, you can use the autofocus attribute on HTML5 compatible browsers. Works even on IE as of version 10.

<input name="myinput" value="whatever" autofocus />

You can use this for 24 hour to 12 hour:

echo date("h:i", strtotime($time));

And for vice versa:

echo date("H:i", strtotime($time));

Use <packages xmlns="urn:packages">in the place of <packages>

You probably want a dict instead of separate variables. For example

d = {}
for i in range(3):
    d["group" + str(i)] = self.getGroup(selected, header+i)

If you insist on actually modifying local variables, you could use the locals function:

for i in range(3):
    locals()["group"+str(i)] = self.getGroup(selected, header+i)

On the other hand, if what you actually want is to modify instance variables of the class you're in, then you can use the setattr function

for i in group(3):
    setattr(self, "group"+str(i), self.getGroup(selected, header+i)

And of course, I'm assuming with all of these examples that you don't just want a list:

groups = [self.getGroup(i,header+i) for i in range(3)]

You can use splice to remove objects or values from an array.

Let's consider an array of length 5, with values 10,20,30,40,50, and I want to remove the value 30 from it.

var array = [10,20,30,40,50];_x000D_
if (array.indexOf(30) > -1) {_x000D_
   array.splice(array.indexOf(30), 1);_x000D_
}_x000D_
console.log(array); // [10,20,40,50]

First of all, you don't need to use a layout inflater to create a simple Button. You can just use:

button = new Button(context);

If you want to style the button you have 2 choices: the simplest one is to just specify all the elements in code, like many of the other answers suggest:

button.setTextColor(Color.RED);
button.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);

The other option is to define the style in XML, and apply it to the button. In the general case, you can use a ContextThemeWrapper for this:

ContextThemeWrapper newContext = new ContextThemeWrapper(baseContext, R.style.MyStyle);
button = new Button(newContext);

To change the text-related attributes on a TextView (or its subclasses like Button) there is a special method:

button.setTextAppearance(R.style.MyTextStyle);

Or, if you need to support devices pre API-23 (Android 6.0)

button.setTextAppearance(context, R.style.MyTextStyle);

This method cannot be used to change all attributes; for example to change padding you need to use a ContextThemeWrapper. But for text color, size, etc. you can use setTextAppearance.

You'll have to do 2 things to make a Bootstrap label (or anything really) adjust sizes based on screen size:

• Use a media query per display size range to adjust the CSS.
• Override CSS sizing set by Bootstrap. You do this by making your CSS rules more specific than Bootstrap's. By default, Bootstrap sets .label { font-size: 75% }. So any extra selector on your CSS rule will make it more specific.

Here's an example CSS listing to accomplish what you are asking, using the default 4 sizes in Bootstrap:

@media (max-width: 767) {
    /* your custom css class on a parent will increase specificity */
    /* so this rule will override Bootstrap's font size setting */
    .autosized .label { font-size: 14px; }
}

@media (min-width: 768px) and (max-width: 991px) {
    .autosized .label { font-size: 16px; }
}

@media (min-width: 992px) and (max-width: 1199px) {
    .autosized .label { font-size: 18px; }
}

@media (min-width: 1200px) {
    .autosized .label { font-size: 20px; }
}

Here is how it could be used in the HTML:

<!-- any ancestor could be set to autosized -->
<div class="autosized">
    ...
        ...
            <span class="label label-primary">Label 1</span>
</div>

If you are using hash or browser history then you can do

hashHistory.push('/login');
browserHistory.push('/login');

Yes, you can run test scripts without a browser, But you should run them in headless mode.

sometimes something wrong in the syntax of the code inside the function throws this error. Check your function correctly. In my case it happened when I was trying to assign Json fields with values and was using colon : to make the assignment instead of equal sign = ...

http://maps.googleapis.com/maps/api/geocode/OUTPUT?address=YOUR_LOCATION&sensor=true

OUTPUT = json or xml;

Hope this will help

This is definitely a permissions issue. If someone is getting this error on linux, make sure you're running the command with sudo as the file most likely is owned by root. Hope that helps!

Follow this steps:

1. php artisan key:generate
2. php artisan config:cache
3. php artisan serve

That suggested error message may duplicate the error message the browser already displays. In chrome, the 2 similar error messages are displayed one after another in the same window.

In chrome, the text displayed after the custom message is: "Are you sure you want to leave this page?". In firefox, it does not display our custom error message at all (but still displays the dialog).

A more appropriate error message might be:

window.onbeforeunload = function() {
    return "If you leave this page, you will lose any unsaved changes.";
}

Or stackoverflow style: "You have started writing or editing a post."

Add a reference to System.Windows.Form.DataVisualization, then add the appropriate using statement:

using System.Windows.Forms.DataVisualization.Charting;

private void CreateChart()
{
    var series = new Series("Finance");

    // Frist parameter is X-Axis and Second is Collection of Y- Axis
    series.Points.DataBindXY(new[] { 2001, 2002, 2003, 2004 }, new[] { 100, 200, 90, 150 });
    chart1.Series.Add(series);

}

Use 'w' and not, 'a'.

if (!$handle = fopen($file, 'w'))

Apart from other answer There are calculator provided by Youtube to check your usage. It is good to identify your usage. https://developers.google.com/youtube/v3/determine_quota_cost

This worked for me... Created file /etc/sudoers.d/90-init-users file with NOPASSWD

echo "user ALL=(ALL)       NOPASSWD:ALL" > 90-init-users

where "user" is your userid.

As others already noted, in one case you are attempting to return cString (which is a char * value in this context - a pointer) from a function that is declared to return a char (which is an integer). In another case you do the reverse: you are assigning a char return value to a char * pointer. This is what triggers the warnings. You certainly need to declare your return values as char *, not as char.

Note BTW that these assignments are in fact constraint violations from the language point of view (i.e. they are "errors"), since it is illegal to mix pointers and integers in C like that (aside from integral constant zero). Your compiler is simply too forgiving in this regard and reports these violations as mere "warnings".

What I also wanted to note is that in several answers you might notice the relatively strange suggestion to return void from your functions, since you are modifying the string in-place. While it will certainly work (since you indeed are modifying the string in-place), there's nothing really wrong with returning the same value from the function. In fact, it is a rather standard practice in C language where applicable (take a look at the standard functions like strcpy and others), since it enables "chaining" of function calls if you choose to use it, and costs virtually nothing if you don't use "chaining".

That said, the assignments in your implementation of compareString look complete superfluous to me (even though they won't break anything). I'd either get rid of them

int compareString(char cString1[], char cString2[]) { 
    // To lowercase 
    strToLower(cString1); 
    strToLower(cString2); 

    // Do regular strcmp 
    return strcmp(cString1, cString2); 
} 

or use "chaining" and do

int compareString(char cString1[], char cString2[]) { 
    return strcmp(strToLower(cString1), strToLower(cString2)); 
} 

(this is when your char * return would come handy). Just keep in mind that such "chained" function calls are sometimes difficult to debug with a step-by-step debugger.

As an additional, unrealted note, I'd say that implementing a string comparison function in such a destructive fashion (it modifies the input strings) might not be the best idea. A non-destructive function would be of a much greater value in my opinion. Instead of performing as explicit conversion of the input strings to a lower case, it is usually a better idea to implement a custom char-by-char case-insensitive string comparison function and use it instead of calling the standard strcmp.

It is:

if [ $# -eq 0 ]
  then
    echo "No arguments supplied"
fi

The $# variable will tell you the number of input arguments the script was passed.

Or you can check if an argument is an empty string or not like:

if [ -z "$1" ]
  then
    echo "No argument supplied"
fi

The -z switch will test if the expansion of "$1" is a null string or not. If it is a null string then the body is executed.

>>> import datetime
>>> d = datetime.datetime.strptime('2011-06-09', '%Y-%m-%d')
>>> d.strftime('%b %d,%Y')
'Jun 09,2011'

In pre-2.5 Python, you can replace datetime.strptime with time.strptime, like so (untested): datetime.datetime(*(time.strptime('2011-06-09', '%Y-%m-%d')[0:6]))

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);       

Yes, you can get exact Keras representation, using pytorch-summary package.

Example for VGG16

from torchvision import models
from torchsummary import summary

vgg = models.vgg16()
summary(vgg, (3, 224, 224))

And in 2016.....I do this (which works in all browsers and does not create "illegal" html).

For the drop-down select that is to show/hide different values add that value as a data attribute.

<select id="animal">
    <option value="1" selected="selected">Dog</option>
    <option value="2">Cat</option>
</select>
<select id="name">
    <option value=""></option>
    <option value="1" data-attribute="1">Rover</option>
    <option value="2" selected="selected" data-attribute="1">Lassie</option>
    <option value="3" data-attribute="1">Spot</option>
    <option value="4" data-attribute="2">Tiger</option>
    <option value="5" data-attribute="2">Fluffy</option>
</select>

Then in your jQuery add a change event to the first drop-down select to filter the second drop-down.

$("#animal").change( function() {
    filterSelectOptions($("#name"), "data-attribute", $(this).val());
});

And the magic part is this little jQuery utility.

function filterSelectOptions(selectElement, attributeName, attributeValue) {
    if (selectElement.data("currentFilter") != attributeValue) {
        selectElement.data("currentFilter", attributeValue);
        var originalHTML = selectElement.data("originalHTML");
        if (originalHTML)
            selectElement.html(originalHTML)
        else {
            var clone = selectElement.clone();
            clone.children("option[selected]").removeAttr("selected");
            selectElement.data("originalHTML", clone.html());
        }
        if (attributeValue) {
            selectElement.children("option:not([" + attributeName + "='" + attributeValue + "'],:not([" + attributeName + "]))").remove();
        }
    }
}

This little gem tracks the current filter, if different it restores the original select (all items) and then removes the filtered items. If the filter item is empty we see all items.

For logging purposes, I'm afraid there's no nicer way of doing this but to construct the string yourself:

string query = cmd.CommandText;

foreach (SqlParameter p in cmd.Parameters)
{
    query = query.Replace(p.ParameterName, p.Value.ToString());
}

By adding using System.Timers; to your program you can use this function:

private static void delay(int Time_delay)
{
   int i=0;
  //  ameTir = new System.Timers.Timer();
    _delayTimer = new System.Timers.Timer();
    _delayTimer.Interval = Time_delay;
    _delayTimer.AutoReset = false; //so that it only calls the method once
    _delayTimer.Elapsed += (s, args) => i = 1;
    _delayTimer.Start();
    while (i == 0) { };
}

Delay is a function and can be used like:

delay(5000);

Intent myIntent = new Intent(MainActivity.this, Katra_home.class);
startActivity(myIntent);

This Should the perfect one :)

You can configure your port in application.properties file in the resources folder of your spring boot project.

server.port="port which you need"

Here is my example:

.box{_x000D_
        _x000D_
        width: 400px; _x000D_
        height: 80px; _x000D_
        background-color: #C9C; _x000D_
        text-align: center; _x000D_
        font: 20px normal Arial, Helvetica, sans-serif; _x000D_
        color: #fff; _x000D_
        padding: 100px 0 0 0;_x000D_
        -webkit-box-shadow: 0 8px 6px -6px black;_x000D_
           -moz-box-shadow: 0 8px 6px -6px black;_x000D_
                box-shadow: 0 8px 6px -6px black;_x000D_
    }

<div class="box">_x000D_
</div>

I believe its in /tmp/. Check your phpinfo function though, it should say session.save_path in there somewhere.

You could try using the system stored procedure sp_help_job. This returns information on the job, its steps, schedules and servers. For example

EXEC msdb.dbo.sp_help_job @Job_name = 'Your Job Name'

SQL Books Online should contain lots of information about the records it returns.

For returning information on multiple jobs, you could try querying the following system tables which hold the various bits of information on the job

• msdb.dbo.SysJobs
• msdb.dbo.SysJobSteps
• msdb.dbo.SysJobSchedules
• msdb.dbo.SysJobServers
• msdb.dbo.SysJobHistory

Their names are fairly self-explanatory (apart from SysJobServers which hold information on when the job last run and the outcome).

Again, information on the fields can be found at MSDN. For example, check out the page for SysJobs

As the others said, you can use Firebug, and that will sort you out no worries on Firefox. Chrome & Safari both have a built-in developer console which has an almost identical interface to Firebug's console, so your code should be portable across those browsers. For other browsers, there's Firebug Lite.

If Firebug isn't an option for you, then try this simple script:

function dump(obj) {
    var out = '';
    for (var i in obj) {
        out += i + ": " + obj[i] + "\n";
    }

    alert(out);

    // or, if you wanted to avoid alerts...

    var pre = document.createElement('pre');
    pre.innerHTML = out;
    document.body.appendChild(pre)
}

I'd recommend against alerting each individual property: some objects have a LOT of properties and you'll be there all day clicking "OK", "OK", "OK", "O... dammit that was the property I was looking for".

Type "gg" in command mode. This brings the cursor to the first line.

A variation. Produces an error if line number is greater than number of lines.

string GetLine(string fileName, int lineNum)
{
    using (StreamReader sr = new StreamReader(fileName))
    {
        string line;
        int count = 1;
        while ((line = sr.ReadLine()) != null)
        {
            if(count == lineNum)
            {
                return line;
            }
            count++;
        }
    }
    return "line number is bigger than number of lines";  
}

Try this

you just use select field id instead of #id (ie.#select_name)

instead of option value use your select option value

 <script>
    $(document).ready(function() {
$("#id option[value='option value']").attr('selected',true);
   });
    </script>

Please use below trick:

• Create an image button with your icon and set its background color to be transparent.
• Put the image button on the EditText
• Implement the 'onclic'k listener of the button to execute your function

Well, this is my final solution for a simple db, for Linux:

# Read this before!
#
# * roles in postgres are users, and can be used also as group of users
# * $ROLE_LOCAL will be the user that access the db for maintenance and
#   administration. $ROLE_REMOTE will be the user that access the db from the webapp
# * you have to change '$ROLE_LOCAL', '$ROLE_REMOTE' and '$DB'
#   strings with your desired names
# * it's preferable that $ROLE_LOCAL == $DB

If you use JSON properly, you can have nested object without any issue :

var xmlhttp = new XMLHttpRequest();   // new HttpRequest instance 
var theUrl = "/json-handler";
xmlhttp.open("POST", theUrl);
xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
xmlhttp.send(JSON.stringify({ "email": "[email protected]", "response": { "name": "Tester" } }));

I'm not sure if this answers your question, but using the IS NULL construct, you can test whether any given scalar expression is NULL:

SELECT * FROM customers WHERE first_name IS NULL

On MS SQL Server, the ISNULL() function returns the first argument if it's not NULL, otherwise it returns the second. You can effectively use this to make sure a query always yields a value instead of NULL, e.g.:

SELECT ISNULL(column1, 'No value found') FROM mytable WHERE column2 = 23

Other DBMSes have similar functionality available.

If you want to know whether a column can be null (i.e., is defined to be nullable), without querying for actual data, you should look into information_schema.

One simple method is to use place to use an image as a background image. This is the type of thing that place is really good at doing.

For example:

background_image=tk.PhotoImage(...)
background_label = tk.Label(parent, image=background_image)
background_label.place(x=0, y=0, relwidth=1, relheight=1)

You can then grid or pack other widgets in the parent as normal. Just make sure you create the background label first so it has a lower stacking order.

Note: if you are doing this inside a function, make sure you keep a reference to the image, otherwise the image will be destroyed by the garbage collector when the function returns. A common technique is to add a reference as an attribute of the label object:

background_label.image = background_image

According to this question, it's totally possible.

Just put all cases that contain the same logic together, and don't put break behind them.

switch (var) {
    case (value1):
    case (value2):
    case (value3):
        //the same logic that applies to value1, value2 and value3
        break;
    case (value4):
        //another logic
        break;
}

It's because case without break will jump to another case until break or return.

EDIT:

Replying the comment, if we really have 95 values with the same logic, but a way smaller number of cases with different logic, we can do:

switch (var) {
     case (96):
     case (97):
     case (98):
     case (99):
     case (100):
         //your logic, opposite to what you put in default.
         break;
     default: 
         //your logic for 1 to 95. we enter default if nothing above is met. 
         break;
}

If you need finer control, if-else is the choice.

If you are using MinGw, rename the mingw32-make.exe to make.exe in the folder " C:\MinGW\bin " or wherever minGw is installed in your system.

To Start Tomcat7 Service :

• Open cmd, go to bin directory within "Apache Tomcat 7" folder. You will see some this like C:\..\bin>

• Enter above command to start the service: C:\..\bin>service.bat install. The service will get started now.

• Enter above command to start tomcat7w monitory service. If you have issue with starting the tomcat7 service then remove the service with command : C:\..\bin>tomcat7 //DS//Tomcat7

• Now the service will no longer exist. Try the install command again, now the service will get installed and started: C:\..\bin>tomcat7w \\MS\tomcat7w

• You will see the tomcat 7 icon in the system tray. Now, the tomcat7 service and tomcat7w will start automatically when the windows get start.

You're looking for the toggle_comment command. (Edit > Comment > Toggle Comment)

By default, this command is mapped to:

• Ctrl+/ (On Windows and Linux)
• Command ?+/ (On Mac)

This command also takes a block argument, which allows you to use block comments instead of single lines (e.g. /* ... */ as opposed to // ... in JavaScript). By default, the following key combinations are mapped to toggle block comments:

• Ctrl+Shift+/ (On Windows and Linux)
• Command ?+Alt+/ (On Mac)

Modern string formatting:

"{} and {}".format("string", 1)

Based on the accepted solution:

function createTable (tableData) {
  const table = document.createElement('table').appendChild(
    tableData.reduce((tbody, rowData) => {
      tbody.appendChild(
        rowData.reduce((tr, cellData) => {
          tr.appendChild(
            document
              .createElement('td')
              .appendChild(document.createTextNode(cellData))
          )
          return tr
        }, document.createElement('tr'))
      )
      return tbody
    }, document.createElement('tbody'))
  )

  document.body.appendChild(table)
}

createTable([
  ['row 1, cell 1', 'row 1, cell 2'],
  ['row 2, cell 1', 'row 2, cell 2']
])

With a simple change it is possible to return the table as HTML element.

What you are using is called a list comprehension in Python, not an inline for-loop (even though it is similar to one). You would write your loop as a list comprehension like so:

p = [q.index(v) if v in q else 99999 for v in vm]

When using a list comprehension, you do not call list.append because the list is being constructed from the comprehension itself. Each item in the list will be what is returned by the expression on the left of the for keyword, which in this case is q.index(v) if v in q else 99999. Incidentially, if you do use list.append inside a comprehension, then you will get a list of None values because that is what the append method always returns.

I'm guessing

x= data[:,0]
y= data[:,1]

Install file loader first:

$ npm install file-loader --save-dev

And add this rule in webpack.config.js

           {
                test: /\.(png|jpg|gif)$/,
                use: [{
                    loader: 'file-loader',
                    options: {}
                }]
            }

unable to verify the first certificate

The certificate chain is incomplete.

It means that the webserver you are connecting to is misconfigured and did not include the intermediate certificate in the certificate chain it sent to you.

Certificate chain

It most likely looks as follows:

1. Server certificate - stores a certificate signed by intermediate.
2. Intermediate certificate - stores a certificate signed by root.
3. Root certificate - stores a self-signed certificate.

Intermediate certificate should be installed on the server, along with the server certificate.
Root certificates are embedded into the software applications, browsers and operating systems.

The application serving the certificate has to send the complete chain, this means the server certificate itself and all the intermediates. The root certificate is supposed to be known by the client.

Recreate the problem

Go to https://incomplete-chain.badssl.com using your browser.

It doesn't show any error (padlock in the address bar is green).
It's because browsers tend to complete the chain if it’s not sent from the server.

Now, connect to https://incomplete-chain.badssl.com using Node:

// index.js
const axios = require('axios');

axios.get('https://incomplete-chain.badssl.com')
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });

Logs: "Error: unable to verify the first certificate".

Solution

You need to complete the certificate chain yourself.

To do that:

1: You need to get the missing intermediate certificate in .pem format, then

2a: extend Node’s built-in certificate store using NODE_EXTRA_CA_CERTS,

2b: or pass your own certificate bundle (intermediates and root) using ca option.

1. How do I get intermediate certificate?

Using openssl (comes with Git for Windows).

Save the remote server's certificate details:

openssl s_client -connect incomplete-chain.badssl.com:443 -servername incomplete-chain.badssl.com | tee logcertfile

We're looking for the issuer (the intermediate certificate is the issuer / signer of the server certificate):

openssl x509 -in logcertfile -noout -text | grep -i "issuer"

It should give you URI of the signing certificate. Download it:

curl --output intermediate.crt http://cacerts.digicert.com/DigiCertSHA2SecureServerCA.crt

Finally, convert it to .pem:

openssl x509 -inform DER -in intermediate.crt -out intermediate.pem -text

2a. NODE_EXTRA_CERTS

I'm using cross-env to set environment variables in package.json file:

"start": "cross-env NODE_EXTRA_CA_CERTS=\"C:\\Users\\USERNAME\\Desktop\\ssl-connect\\intermediate.pem\" node index.js"

2b. ca option

This option is going to overwrite the Node's built-in root CAs.

That's why we need to create our own root CA. Use ssl-root-cas.

Then, create a custom https agent configured with our certificate bundle (root and intermediate). Pass this agent to axios when making request.

// index.js
const axios = require('axios');
const path = require('path');
const https = require('https');
const rootCas = require('ssl-root-cas').create();

rootCas.addFile(path.resolve(__dirname, 'intermediate.pem'));
const httpsAgent = new https.Agent({ca: rootCas});

axios.get('https://incomplete-chain.badssl.com', { httpsAgent })
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });

Instead of creating a custom https agent and passing it to axios, you can place the certifcates on the https global agent:

// Applies to ALL requests (whether using https directly or the request module)
https.globalAgent.options.ca = rootCas;

So... if you are running your containers using a Rancher server, Rancher v1.6 (not sure if 2.0 has this) containers have access to http://rancher-metadata/ which has a lot of useful information.

From inside the container the IP address can be found here: curl http://rancher-metadata/latest/self/host/agent_ip

For more details see: https://rancher.com/docs/rancher/v1.6/en/rancher-services/metadata-service/

The default Locale is constructed statically at runtime for your application process from the system property settings, so it will represent the Locale selected on that device when the application was launched. Typically, this is fine, but it does mean that if the user changes their Locale in settings after your application process is running, the value of getDefaultLocale() probably will not be immediately updated.

If you need to trap events like this for some reason in your application, you might instead try obtaining the Locale available from the resource Configuration object, i.e.

Locale current = getResources().getConfiguration().locale;

You may find that this value is updated more quickly after a settings change if that is necessary for your application.

You have different choices to handle this. It seem like its taking us back to old good plain SQL days :)

Read this: http://www.javacodegeeks.com/2012/07/four-solutions-to-lazyinitializationexc_05.html

I think that you can consider changing your markup. If I am not wrong, you'd like to put an invisible layer above the document and your invisible markup may be preceding your document image (is this correct?).

Instead, I propose that you put the invisible right after the document image but changing the position to absolute.

Notice that you need a parent element to have position: relative and then you will be able to use this idea. Otherwise your absolute layer will be placed just in the top left corner.

An absolute position element is positioned relative to the first parent element that has a position other than static. If no such element is found, the containing block is html

Hope this helps. See here for more information about CSS positioning.

1. Wrap the <input type="file"> with a <label> tag;
2. Add a tag (with the text that you need) inside the label, like a <span> or <a>;
3. Make this tag look like a button;
4. Make input[type="file"] invisible via display: none.

If you are using Visual Studio, then you can use "Start Without Debugging" in the Debug menu.

It will automatically write "Press any key to continue . . ." to the console for you upon completion of the application and it will leave the console open for you until a key is pressed.

To be able to detect unused imports, code or variables, make sure you have this options in tsconfig.json file

"compilerOptions": {
    "noUnusedLocals": true,
    "noUnusedParameters": true
}

have the typescript compiler installed, ifnot install it with:

npm install -g typescript

and the tslint extension installed in Vcode, this worked for me, but after enabling I notice an increase amount of CPU usage, specially on big projects.

I would also recomend using typescript hero extension for organizing your imports.

Note that following gnarf's idea you can also do:

var js = "alert('B:' + this.id); return false;";<br/>
var newclick = eval("(function(){"+js+"});");<br/>
$("a").get(0).onclick = newclick;

That will set the onclick without triggering the event (had the same problem here and it took me some time to find out).

Typically, git commit brings up an interactive editor (on Linux, and possibly Cygwin, determined by the contents of your $EDITOR environment variable) for you to edit your commit message in. When you save and exit, the commit completes.

You should make sure that the changes you are trying to commit have been added to the Git index; this determines what is committed. See http://gitref.org/basic/ for details on this.

I tried the binding according to the answer by @Szymon but It did not work for me. I tried basicHttpsBinding which is new in .net 4.5 and It solved the issue. Here is the complete configuration that works for me.

    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="false" />
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <basicHttpsBinding>
        <binding name="basicHttpsBindingForYourService">
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"/>
          </security>
        </binding>
      </basicHttpsBinding>
    </bindings>
    <services>
      <service name="YourServiceName">
        <endpoint address="" binding="basicHttpsBinding" bindingName="basicHttpsBindingForYourService" contract="YourContract" />
      </service>
    </services>   
</system.serviceModel>

FYI: My application's target framework is 4.5.1. IIS web site that I created to deploy this wcf service only has https binding enabled.

If you are talking about <input type=button>, it won't automatically submit the form

if you are talking about the <button> tag, that's newer and doesn't automatically submit in all browsers.

Bottom line, if you want the form to submit on click in all browsers, use <input type="submit">

I had the same issue in both VS 2010 and VS 2012. On my system the first static lib was built and then got immediately deleted when the main project started building.

The problem is the common intermediate folder for several projects. Just assign separate intermediate folder for each project.

Read more on this here

The current directory is not (necessarily) the directory the .class file is in. It's working directory of the process. (ie: the directory you were in when you started the JVM)

You can load files from the same directory^* as the .class file with getResourceAsStream(). That'll give you an InputStream which you can convert to a Reader with InputStreamReader.

_{^*Note that this "directory" may actually be a jar file, depending on where the class was loaded from.}

To Answer your first question, Jenkins variables are case sensitive. However, if you are writing a windows batch script, they are case insensitive, because Windows doesn't care about the case.

Since you are not very clear about your setup, let's make the assumption that you are using an ant build step to fire up your ant task. Have a look at the Jenkins documentation (same page that Adarsh gave you, but different chapter) for an example on how to make Jenkins variables available to your ant task.

EDIT:

Hence, I will need to access the environmental variable ${BUILD_NUMBER} to construct the URL.

Why don't you use $BUILD_URL then? Isn't it available in the extended email plugin?

I just had to implement a RESTfull api where I need to pass parameters. I did this by passing the parameters in the query string in the same style as described by Mark's first example "api/controller?start=date1&end=date2"

In the controller I used a tip from URL split in C#?

// uri: /api/courses
public IEnumerable<Course> Get()
{
    NameValueCollection nvc = HttpUtility.ParseQueryString(Request.RequestUri.Query);
    var system = nvc["System"];
    // BL comes here
    return _courses;
}

In my case I was calling the WebApi via Ajax looking like:

$.ajax({
        url: '/api/DbMetaData',
        type: 'GET',
        data: { system : 'My System',
                searchString: '123' },
        dataType: 'json',
        success: function (data) {
                  $.each(data, function (index, v) {
                  alert(index + ': ' + v.name);
                  });
         },
         statusCode: {
                  404: function () {
                       alert('Failed');
                       }
        }
   });

I hope this helps...

In ONLINE mode the new index is built while the old index is accessible to reads and writes. any update on the old index will also get applied to the new index. An antimatter column is used to track possible conflicts between the updates and the rebuild (ie. delete of a row which was not yet copied). See Online Index Operations. When the process is completed the table is locked for a brief period and the new index replaces the old index. If the index contains LOB columns, ONLINE operations are not supported in SQL Server 2005/2008/R2.

In OFFLINE mode the table is locked upfront for any read or write, and then the new index gets built from the old index, while holding a lock on the table. No read or write operation is permitted on the table while the index is being rebuilt. Only when the operation is done is the lock on the table released and reads and writes are allowed again.

Note that in SQL Server 2012 the restriction on LOBs was lifted, see Online Index Operations for indexes containing LOB columns.

I came to this question looking to restore a file I just deleted but I hadn't yet committed the change. Just in case you find yourself in this situation, all you need to do is the following:

git checkout HEAD -- path/to/file.ext

http://en.wikipedia.org/wiki/Post/Redirect/Get

The most common way to implement this pattern in ASP.Net is to use Response.Redirect(Request.RawUrl)

Consider the differences between Redirect and Transfer. Transfer really isn't telling the browser to forward to a clear form, it's simply returning a cleared form. That may or may not be what you want.

Response.Redirect() does not a waste round trip. If you post to a script that clears the form by Server.Transfer() and reload you will be asked to repost by most browsers since the last action was a HTTP POST. This may cause your users to unintentionally repeat some action, eg. place a second order which will have to be voided later.

OQ asked about static string vs const. Both have different use cases (although both are treated as static).

Use const only for truly constant values (e.g. speed of light - but even this varies depending on medium). The reason for this strict guideline is that the const value is substituted into the uses of the const in assemblies that reference it, meaning you can have versioning issues should the const change in its place of definition (i.e. it shouldn't have been a constant after all). Note this even affects private const fields because you might have base and subclass in different assemblies and private fields are inherited.

Static fields are tied to the type they are declared within. They are used for representing values that need to be the same for all instances of a given type. These fields can be written to as many times as you like (unless specified readonly).

If you meant static readonly vs const, then I'd recommend static readonly for almost all cases because it is more future proof.

There are optimizations the compiler can't do because they only work for a reduced set of inputs.

Below there is c++ sample code that can do a faster division doing a 64bits "Multiplication by the reciprocal". Both numerator and denominator must be below certain threshold. Note that it must be compiled to use 64 bits instructions to be actually faster than normal division.

#include <stdio.h>
#include <chrono>

static const unsigned s_bc = 32;
static const unsigned long long s_p = 1ULL << s_bc;
static const unsigned long long s_hp = s_p / 2;

static unsigned long long s_f;
static unsigned long long s_fr;

static void fastDivInitialize(const unsigned d)
{
    s_f = s_p / d;
    s_fr = s_f * (s_p - (s_f * d));
}

static unsigned fastDiv(const unsigned n)
{
    return (s_f * n + ((s_fr * n + s_hp) >> s_bc)) >> s_bc;
}

static bool fastDivCheck(const unsigned n, const unsigned d)
{
    // 32 to 64 cycles latency on modern cpus
    const unsigned expected = n / d;

    // At least 10 cycles latency on modern cpus
    const unsigned result = fastDiv(n);

    if (result != expected)
    {
        printf("Failed for: %u/%u != %u\n", n, d, expected);
        return false;
    }

    return true;
}

int main()
{
    unsigned result = 0;

    // Make sure to verify it works for your expected set of inputs
    const unsigned MAX_N = 65535;
    const unsigned MAX_D = 40000;

    const double ONE_SECOND_COUNT = 1000000000.0;

    auto t0 = std::chrono::steady_clock::now();
    unsigned count = 0;
    printf("Verifying...\n");
    for (unsigned d = 1; d <= MAX_D; ++d)
    {
        fastDivInitialize(d);
        for (unsigned n = 0; n <= MAX_N; ++n)
        {
            count += !fastDivCheck(n, d);
        }
    }
    auto t1 = std::chrono::steady_clock::now();
    printf("Errors: %u / %u (%.4fs)\n", count, MAX_D * (MAX_N + 1), (t1 - t0).count() / ONE_SECOND_COUNT);

    t0 = t1;
    for (unsigned d = 1; d <= MAX_D; ++d)
    {
        fastDivInitialize(d);
        for (unsigned n = 0; n <= MAX_N; ++n)
        {
            result += fastDiv(n);
        }
    }
    t1 = std::chrono::steady_clock::now();
    printf("Fast division time: %.4fs\n", (t1 - t0).count() / ONE_SECOND_COUNT);

    t0 = t1;
    count = 0;
    for (unsigned d = 1; d <= MAX_D; ++d)
    {
        for (unsigned n = 0; n <= MAX_N; ++n)
        {
            result += n / d;
        }
    }
    t1 = std::chrono::steady_clock::now();
    printf("Normal division time: %.4fs\n", (t1 - t0).count() / ONE_SECOND_COUNT);

    getchar();
    return result;
}

I required a specific colour, so filter didn't work for me.

Instead, I created a div, exploiting CSS multiple background images and the linear-gradient function (which creates an image itself). If you use the overlay blend mode, your actual image will be blended with the generated "gradient" image containing your desired colour (here, #BADA55)

.colored-image {_x000D_
        background-image: linear-gradient(to right, #BADA55, #BADA55), url("https://i.imgur.com/lYXT8R6.png");_x000D_
        background-blend-mode: overlay;_x000D_
        background-size: contain;_x000D_
        width: 200px;_x000D_
        height: 200px;        _x000D_
    }

<div class="colored-image"></div>

The virtual keyword in C# enables a method or property to be overridden by child classes. For more information please refer to the MSDN documentation on the 'virtual' keyword

_{UPDATE: This doesn't answer the question as currently asked, but I'll leave it here for anyone looking for a simple answer to the original, non-descriptive question asked.}

Try:

<div style="@(Model.booleanVariable ? "display:block" : "display:none")">Some links</div>

Use the "Display" style attribute with your bool model attribute to define the div's visibility.

I know this sounds a bit weird but have any of you tried to set the margin of the form page body tag to 0.

The problem is actually pretty simple, the reason is that the body tag margin by default is set to 8px (depending on browser) and if you just set it to 0 then it fixes the scrollbar.

The js configuration I have is as follows and it works well without changing the css of fancybox.

$(".iframe").fancybox({
    'autoScale'         : false,
    'autoDimensions'    : false,
    'transitionIn'      : 'none',
    'transitionOut'     : 'none',
    'type'              : 'iframe'
});

OP asked for users connected to a particular database:

-- Who's currently connected to my_great_database?
SELECT * FROM pg_stat_activity 
  WHERE datname = 'my_great_database';

This gets you all sorts of juicy info (as others have mentioned) such as

• userid (column usesysid)
• username (usename)
• client application name (appname), if it bothers to set that variable -- psql does :-)
• IP address (client_addr)
• what state it's in (a couple columns related to state and wait status)
• and everybody's favorite, the current SQL command being run (query)

For this particular relationship, you could use np.sign:

>>> df["C"] = np.sign(df.A - df.B)
>>> df
   A  B  C
a  2  2  0
b  3  1  1
c  1  3 -1

Some may take issue with changing the Bootstrap js (and perhaps validly so) but here is a two line approach to achieving this.

In bootstrap.js, look for the Collapse.prototype.show function and modify the this.$trigger call to add the html change as follows:

this.$trigger
  .removeClass('collapsed')
  .attr('aria-expanded', true)
  .html('Collapse')

Likewise in the Collapse.prototype.hide function change it to

this.$trigger
  .addClass('collapsed')
  .attr('aria-expanded', false)
  .html('Expand')

This will toggle the text between "Collapse" when everything is expanded and "Expand" when everything is collapsed.

Two lines. Done.

EDIT: longterm this won't work. bootstrap.js is part of a Nuget package so I don't think it was propogating my change to the server. As mentioned previously, not best practice anyway to edit bootstrap.js, so I implemented PSL's solution which worked great. Nonetheless, my solution will work locally if you need something quick just to try it out.

You can use "dd/MM/yyyy" format for using it in DateTime.ParseExact.

Converts the specified string representation of a date and time to its DateTime equivalent using the specified format and culture-specific format information. The format of the string representation must match the specified format exactly.

DateTime date = DateTime.ParseExact("24/01/2013", "dd/MM/yyyy", CultureInfo.InvariantCulture);

Here is a DEMO.

For more informations, check out Custom Date and Time Format Strings

If the list is empty I get an exception. This solution will take into account this issue:

int maxAge = context.Persons.Select(p => p.Age).DefaultIfEmpty(0).Max();

Try this using list comprehension:

import pandas as pd

df = pd.DataFrame(
    [p, p.team, p.passing_att, p.passer_rating()] for p in game.players.passing()
)

I know this is a pretty old topic but it might come in handy for anyone in the future. the script below does what the fella was trying to achieve purely using vbscript. when sorted terms starting in capital letters will have priority.

for a = UBound(ArrayOfTerms) - 1 To 0 Step -1
    for j= 0 to a
        if ArrayOfTerms(j)>ArrayOfTerms(j+1) then
            temp=ArrayOfTerms(j+1)
            ArrayOfTerms(j+1)=ArrayOfTerms(j)
            ArrayOfTerms(j)=temp
        end if
    next
next 

As an update...with ECMAScript 6 you can FINALLY set default values in function parameter declarations like so:

function f (x, y = 7, z = 42) {
  return x + y + z
}

f(1) === 50

As referenced by - http://es6-features.org/#DefaultParameterValues

Yeah Got it...

Date dob=null;
DateFormat df=new SimpleDateFormat("dd/MM/yyyy");
dob=df.parse( "13/06/1983" );
GregorianCalendar cal = new GregorianCalendar();
cal.setTime(dob);
XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance().newXMLGregorianCalendarDate(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH)+1, cal.get(Calendar.DAY_OF_MONTH), DatatypeConstants.FIELD_UNDEFINED);

This will give it in correct format.

The two approaches are not interchangeable. You should initialize state in the constructor when using ES6 classes, and define the getInitialState method when using React.createClass.

See the official React doc on the subject of ES6 classes.

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = { /* initial state */ };
  }
}

is equivalent to

var MyComponent = React.createClass({
  getInitialState() {
    return { /* initial state */ };
  },
});

You'll need a script to loop through them. Git doesn't a provide a "push all." You could theoretically do a push in multiple threads, but a native method is not available.

Fetch is even more complicated, and I'd recommend doing that linearly.

I think your best answer is to have once machine that everybody does a push / pull to, if that's at all possible.

On Windows 10, using Ionic, what worked great to me was combine 'findstr' with the "INFO:CONSOLE" generated by all App messages. So, my command in command line is:

adb logcat | findstr INFO:CONSOLE

when you add context:component-scan for the first time in an xml, the following needs to be added.

xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

I would use:

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {

    super.touchesBegan(touches, withEvent: event)
    let touch : UITouch = touches.anyObject() as UITouch

    if let touchView = touch.view as? UIPickerView
    {

    }
}

Your comment suggests you're trying to call this from a programming language. If that's the case, can your program fork a child process that calls sleep then does the work?

What about having your program calculate the number of seconds until the desired runtime, and have it call shell_exec("sleep ${secondsToWait) ; myCommandToRun");

If you want to make multiple operation use

select (sel1.s1+sel2+s2)

(select sum(hours) s1 from resource) sel1
join 
(select sum(hours) s2 from projects-time)sel2
on sel1.s1=sel2.s2

Short Answer

Yes.

Explanation

It is a good practice since an element can be a part of different groups, and you may want specific elements to be a part of more than one group. The element can hold an infinite number of classes in HTML5, while in HTML4 you are limited by a specific length.

The following example will show you the use of multiple classes.

The first class makes the text color red.

The second class makes the background-color blue.

See how the DOM Element with multiple classes will behave, it will wear both CSS statements at the same time.

Result: multiple CSS statements in different classes will stack up.

You can read more about CSS Specificity.

CSS

.class1 {
    color:red;
}

.class2 {
    background-color:blue;
}

HTML

<div class="class1">text 1</div>
<div class="class2">text 2</div>
<div class="class1 class2">text 3</div>

Live demo

The substitute command can be applied to a visual selection. Make a visual block over the lines that you want to change, and type :, and notice that the command-line is initialized like this: :'<,'>. This means that the substitute command will operate on the visual selection, like so:

:'<,'>s/$/,/

And this is a substitution that should work for your example, assuming that you really want the comma at the end of each line as you've mentioned. If there are trailing spaces, then you may need to adjust the command accordingly:

:'<,'>s/\s*$/,/

This will replace any amount of whitespace preceding the end of the line with a comma, effectively removing trailing whitespace.

The same commands can operate on a range of lines, e.g. for the next 5 lines: :,+5s/$/,/, or for the entire buffer: :%s/$/,/.

WHILE EXISTS (SELECT * FROM TableName WHERE Value <> 'abc1' AND Parameter1 = 'abc' AND Parameter2 = 123)
BEGIN
UPDATE TOP (1000) TableName
SET Value = 'abc1'
WHERE Parameter1 = 'abc' AND Parameter2 = 123 AND Value <> 'abc1'
END

A variable cannot be both null and undefined at the same time. However, the direct answer to your question is:

if (variable != null)

One =, not two.

There are two special clauses in the "abstract equality comparison algorithm" in the JavaScript spec devoted to the case of one operand being null and the other being undefined, and the result is true for == and false for !=. Thus if the value of the variable is undefined, it's not != null, and if it's not null, it's obviously not != null.

Now, the case of an identifier not being defined at all, either as a var or let, as a function parameter, or as a property of the global context is different. A reference to such an identifier is treated as an error at runtime. You could attempt a reference and catch the error:

var isDefined = false;
try {
  (variable);
  isDefined = true;
}
catch (x) {}

I would personally consider that a questionable practice however. For global symbols that may or may be there based on the presence or absence of some other library, or some similar situation, you can test for a window property (in browser JavaScript):

var isJqueryAvailable = window.jQuery != null;

or

var isJqueryAvailable = "jQuery" in window;

As stated in problem, to solve this error you MUST use correct annotations. In above problem, @NotBlank or @NotEmpty annotation must be applied on any String field only.

To validate long type field, use annotation @NotNull.

To understand the difference between a scripting language and a programming language, one has to understand why scripting languages were born.

Initially, there were programming languages that was written to build programs like excel, word, browsers, games and etc. These programs were built with languages like c and java. Overtime, these programs needed a way for users to create new functionality, so they had to provide an interface to their bytecode and hence scripting languages were born.

A scripting language usually isnt compiled so can run as soon as you write something meaningful. Hence excel may be built using C++ but it exposes a scripting language called VBA for users to define functionality. Similarly browsers may be built with C++/Java but they expose a scripting language called javascript (not related to java in any way). Games, are usually built with C++ but expose a language called Lua for users to define custom functionality.

A scripting language usually sits behind some programming language. Scripting languages usually have less access to the computers native abilities since they run on a subset of the original programming language. An example here is that Javascript will not be able to access your file system. Scripting languages are usually slower than programming languages.

Although scripting languages may have less access and are slower, they can be very powerful tools. One factor attributing to a scripting languages success is the ease of updating. Do you remember the days of java applets on the web, this is an example of running a programming language (java) vs running a scripting language (javascript). At the time, computers were not as powerful and javascript wasn't as mature so Java applets dominated the scenes. But Java applets were annoying, they required the user to sort of load and compile the language. Fast forward to today, Java applets are almost extinct and Javascript dominates the scene. Javascript is extremely fast to load since most of the browser components have been installed already.

Lastly, scripting languages are also considered programming languages (although some people refuse to accept this) - the term we should be using here is scripting languages vs compiled languages.

Compare date only instead of date + time (NOW) with:

CURDATE()

Here's a simple way

for (i in 1:10) {
  
  skip_to_next <- FALSE
  
  # Note that print(b) fails since b doesn't exist
  
  tryCatch(print(b), error = function(e) { skip_to_next <<- TRUE})
  
  if(skip_to_next) { next }     
}

Note that the loop completes all 10 iterations, despite errors. You can obviously replace print(b) with any code you want. You can also wrap many lines of code in { and } if you have more than one line of code inside the tryCatch

You can set the width in pixels via inline styling:

<input type="text" name="text" style="width: 195px;">

You can also set the width with a visible character length:

<input type="text" name="text" size="35">

As @swanliu pointed out it is due to a bad connection.
However before adjusting the server timing and client timeout , I would first try and use a better connection pooling strategy.

Connection Pooling

Hibernate itself admits that its connection pooling strategy is minimal

Hibernate's own connection pooling algorithm is, however, quite rudimentary. It is intended to help you get started and is not intended for use in a production system, or even for performance testing. You should use a third party pool for best performance and stability. Just replace the hibernate.connection.pool_size property with connection pool specific settings. This will turn off Hibernate's internal pool. For example, you might like to use c3p0.
As stated in Reference : http://docs.jboss.org/hibernate/core/3.3/reference/en/html/session-configuration.html

I personally use C3P0. however there are other alternatives available including DBCP.
Check out

• http://www.mchange.com/projects/c3p0/index.html
• http://commons.apache.org/dbcp/

Below is a minimal configuration of C3P0 used in my application:

<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
<property name="c3p0.acquire_increment">1</property> 
<property name="c3p0.idle_test_period">100</property> <!-- seconds --> 
<property name="c3p0.max_size">100</property> 
<property name="c3p0.max_statements">0</property> 
<property name="c3p0.min_size">10</property> 
<property name="c3p0.timeout">1800</property> <!-- seconds --> 

By default, pools will never expire Connections. If you wish Connections to be expired over time in order to maintain "freshness", set maxIdleTime and/or maxConnectionAge. maxIdleTime defines how many seconds a Connection should be permitted to go unused before being culled from the pool. maxConnectionAge forces the pool to cull any Connections that were acquired from the database more than the set number of seconds in the past.
As stated in Reference : http://www.mchange.com/projects/c3p0/index.html#managing_pool_size

Edit:
I updated the configuration file (Reference), as I had just copy pasted the one for my project earlier. The timeout should ideally solve the problem, If that doesn't work for you there is an expensive solution which I think you could have a look at:

Create a file “c3p0.properties” which must be in the root of the classpath (i.e. no way to override it for particular parts of the application). (Reference)

# c3p0.properties
c3p0.testConnectionOnCheckout=true

With this configuration each connection is tested before being used. It however might affect the performance of the site.

If you give the code a .c extension the compiler thinks it is C code, not C++. And the C++ compiler driver is called g++, if you use the gcc driver you will have linker problems, as the standard C++ libraries will not be linked by default. So you want:

g++ myprog.cpp

And do not even consider using an uppercase .C extension, unless you never want to port your code, and are prepared to be hated by those you work with.

Thanks Darin, For me, to be able to post to the create method, It only worked after I modified the BindModel code to :

public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
    var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
    var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

    if (!string.IsNullOrEmpty(displayFormat) && value != null)
    {
        DateTime date;
        displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
        // use the format specified in the DisplayFormat attribute to parse the date
         if (DateTime.TryParse(value.AttemptedValue, CultureInfo.GetCultureInfo("en-GB"), DateTimeStyles.None, out date))
        {
            return date;
        }
        else
        {
            bindingContext.ModelState.AddModelError(
                bindingContext.ModelName,
                string.Format("{0} is an invalid date format", value.AttemptedValue)
            );
        }
    }

    return base.BindModel(controllerContext, bindingContext);
}

Hope this could help someone else...

None of these solutions worked for me when mousing over/out of objects created after the document has loaded as the question requests. I know this question is old but I have a solution for those still looking:

$("#container").on('mouseenter', '.selector', function() {
    //do something
});
$("#container").on('mouseleave', '.selector', function() {
    //do something
});

This will bind the functions to the selector so that objects with this selector made after the document is ready will still be able to call it.

for more exactly positioning:

      background-position: bottom 5px right 7px;

Open angular.json file and find budgets keyword.

It should look like:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "2mb",
          "maximumError": "5mb"
       }
    ]

As you’ve probably guessed you can increase the maximumWarning value to prevent this warning, i.e.:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "4mb", <===
          "maximumError": "5mb"
       }
    ]

What does budgets mean?

A performance budget is a group of limits to certain values that affect site performance, that may not be exceeded in the design and development of any web project.

In our case budget is the limit for bundle sizes.

Considering 'when':
I tend to declare everything as private initially, if I'm not exactly sure. Reason being, that it's usually much easier to turn a private method public than the other way round. That's because you can at least be sure that the private method hasn't been used anywhere but in the class itself. A public method may already be in use everywhere, possibly requiring an extensive re-write.

Update: i go for a default of protected nowadays, because I've come to find that it's good enough for encapsulation and doesn't get in the way when I'm extending classes (which i try to avoid anyway). Only if i have a good reason to use the other two, i will.

A good reason for a private method would be one that implements something inherent to that object that even an extending class should not change (factual reason, in addition to encapsulation, like internal state management). Eventually, it's still easy enough to track down where a protected method is being used usually, so i default to protected nowadays. Maybe not 100% objective "in the trenches" experience, I admit.

to position the dialog in the center of the screen :

$('#my-selector').parent().position({
                    my: "center",
                    at: "center",
                    of: window
});

yes, simply use colspan.

I'd like to visualize the difference. Suppose we have:

class A { }
class B extends A { }
class C extends B { }

List<? extends T> - reading and assigning:

|-------------------------|-------------------|---------------------------------|
|         wildcard        |        get        |              assign             |
|-------------------------|-------------------|---------------------------------|
|    List<? extends C>    |    A    B    C    |                       List<C>   |
|-------------------------|-------------------|---------------------------------|
|    List<? extends B>    |    A    B         |             List<B>   List<C>   |
|-------------------------|-------------------|---------------------------------|
|    List<? extends A>    |    A              |   List<A>   List<B>   List<C>   |
|-------------------------|-------------------|---------------------------------|

List<? super T> - writing and assigning:

|-------------------------|-------------------|-------------------------------------------|
|         wildcard        |        add        |                   assign                  |
|-------------------------|-------------------|-------------------------------------------|
|     List<? super C>     |              C    |  List<Object>  List<A>  List<B>  List<C>  |
|-------------------------|-------------------|-------------------------------------------|
|     List<? super B>     |         B    C    |  List<Object>  List<A>  List<B>           |
|-------------------------|-------------------|-------------------------------------------|
|     List<? super A>     |    A    B    C    |  List<Object>  List<A>                    |
|-------------------------|-------------------|-------------------------------------------|

In all of the cases:

• you can always get Object from a list regardless of the wildcard.
  
• you can always add null to a mutable list regardless of the wildcard.

i have a simple solution without lot of changes. the initial statement is

I want to break the if statement above and stop executing echo "yes"; or such codes which are no longer necessary to be executed, there may be or may not be an additional condition, is there way to do this?

so, it seem simple. try code like this.

$a="test";
if("test"==$a)
{
  if (1==0){
      echo "yes"; // this line while never be executed. 
      // and can be reexecuted simply by changing if (1==0) to if (1==1) 
  }
}
echo "finish";

if you want to try without this code, it's simple. and you can back when you want. another solution is comment blocks. or simply thinking and try in another separated code and copy paste only the result in your final code. and if a code is no longer nescessary, in your case, the result can be

$a="test";
echo "finish";

with this code, the original statement is completely respected.. :) and more readable!

scp remote:"[A-C]/[12].txt" local:

If after changing the namespace and the config/auth.php it still fails, you could try the following:

1. In the file vendor/composer/autoload_classmap.php change the line App\\User' => $baseDir . '/app/User.php',, to App\\Models\\User' => $baseDir . '/app/Models/User.php',

2. At the beginning of the file app/Services/Registrar.php change "use App\User" to "App\Models\User"

Despite this being against the general SO policy on these matters, this seems to be what the OP genuinely wants:

http://www.google.com/search?btnG=1&pws=0&q=java+executable+wrapper

If you'd like, you could also try creating the appropriate batch or script file containing the single line:

java -jar MyJar.jar

Or in many cases on windows just double clicking the executable jar.

Add an item and set its "Selected" property to true, you will probably want to set "appenddatabounditems" property to true also so your initial value isn't deleted when databound.

If you are talking about setting an initial value that is in your databound items then hook into your ondatabound event and set which index you want to selected=true you will want to wrap it in "if not page.isPostBack then ...." though

Protected Sub DepartmentDropDownList_DataBound(ByVal sender As Object, ByVal e As    System.EventArgs) Handles DepartmentDropDownList.DataBound
    If Not Page.IsPostBack Then
        DepartmentDropDownList.SelectedValue = "somevalue"
    End If
End Sub

I have humbly modified a bit Alundaio code:

HTTP Solution

From the documentation, "the right way is to define a separate server for example.org":

server {
    listen       80;
    server_name  example.com;
    return       301 http://www.example.com$request_uri;
}

server {
    listen       80;
    server_name  www.example.com;
    ...
}

HTTPS Solution

For those who want a solution including https://...

server {
        listen 80;
        server_name www.domain.com;
        # $scheme will get the http protocol
        # and 301 is best practice for tablet, phone, desktop and seo
        return 301 $scheme://domain.com$request_uri;
}

server {
        listen 80;
        server_name domain.com;
        # here goes the rest of your config file
        # example 
        location / {

            rewrite ^/cp/login?$ /cp/login.php last;
            # etc etc...

        }
}

Note: I have not originally included https:// in my solution since we use loadbalancers and our https:// server is a high-traffic SSL payment server: we do not mix https:// and http://.

To check the nginx version, use nginx -v.

Strip www from url with nginx redirect

server {
    server_name  www.domain.com;
    rewrite ^(.*) http://domain.com$1 permanent;
}

server {
    server_name  domain.com;
    #The rest of your configuration goes here#
}

So you need to have TWO server codes.

Add the www to the url with nginx redirect

If what you need is the opposite, to redirect from domain.com to www.domain.com, you can use this:

server {
    server_name  domain.com;
    rewrite ^(.*) http://www.domain.com$1 permanent;
}

server {
    server_name  www.domain.com;
    #The rest of your configuration goes here#
}

As you can imagine, this is just the opposite and works the same way the first example. This way, you don't get SEO marks down, as it is complete perm redirect and move. The no WWW is forced and the directory shown!

Some of my code shown below for a better view:

server {
    server_name  www.google.com;
    rewrite ^(.*) http://google.com$1 permanent;
}
server {
       listen 80;
       server_name google.com;
       index index.php index.html;
       ####
       # now pull the site from one directory #
       root /var/www/www.google.com/web;
       # done #
       location = /favicon.ico {
                log_not_found off;
                access_log off;
       }
}

In this document it states:

There is (intentionally) no direct declarative way to define either prototype data properties (other than methods) class properties, or instance property

This means that it is intentionally like this.

Maybe you can define a variable in the constructor?

constructor(){
    this.key = value
}

Can I ask why this is important?

I know that this is not a direct answer to your question, but the fact that you are trying to preserve the object ID of a string might indicate that you should look again at what you are trying to do.

You might find, for instance, that relying on the object ID of a string will lead to bugs that are quite hard to track down.

Kinesics Text Editor.

It's super fast and handles large text files, though minimal in features. There's a GUI version and console version (k.exe) included. Should work the same on linux.

Example: In my test it took 7 seconds to open a 500mb disk image.

Just ask yourself: "is it an exceptional case that the object is not found"? If it is expected to happen in the normal course of your program, you probably should not raise an exception (since it is not exceptional behavior).

Short version: use exceptions to handle exceptional behavior, not to handle normal flow of control in your program.

-Alan.

var idPost=document.getElementById("status").innerHTML;

The 'status' element does not exist in your webpage.

So document.getElementById("status") return null. While you can not use innerHTML property of NULL.

You should add a condition like this:

if(document.getElementById("status") != null){
    var idPost=document.getElementById("status").innerHTML;
}

Hope this answer can help you. :)

Abstract methods means there is no default implementation for it and an implementing class will provide the details.

Essentially, you would have

abstract class AbstractObject {
   public abstract void method();
}

class ImplementingObject extends AbstractObject {
  public void method() {
    doSomething();
  }
}

So, it's exactly as the error states: your abstract method can not have a body.

There's a full tutorial on Oracle's site at: http://download.oracle.com/javase/tutorial/java/IandI/abstract.html

The reason you would do something like this is if multiple objects can share some behavior, but not all behavior.

A very simple example would be shapes:

You can have a generic graphic object, which knows how to reposition itself, but the implementing classes will actually draw themselves.

(This is taken from the site I linked above)

abstract class GraphicObject {
    int x, y;
    ...
    void moveTo(int newX, int newY) {
        ...
    }
    abstract void draw();
    abstract void resize();
}

class Circle extends GraphicObject {
    void draw() {
        ...
    }
    void resize() {
        ...
    }
}
class Rectangle extends GraphicObject {
    void draw() {
        ...
    }
    void resize() {
        ...
    }
}

There is no difference between environment variables and variables in a script. Environment variables are just defined earlier, outside the script, before the script is called. From the script's point of view, a variable is a variable.

You can check if a variable is defined:

if [ -z "$a" ]
then
    echo "not defined"
else 
    echo "defined"
fi

and then set a default value for undefined variables or do something else.

The -z checks for a zero-length (i.e. empty) string. See man bash and look for the CONDITIONAL EXPRESSIONS section.

You can also use set -u at the beginning of your script to make it fail once it encounters an undefined variable, if you want to avoid having an undefined variable breaking things in creative ways.

I would like to submit for the contest a gem called chaos-pp, which implements a functional language by means of the preprocessor macros.

One of the examples is calculating the 500th fibonacci number entirely by the preprocessor:

The original code before preprocessor looks as this:

int main(void) {
   printf
     ("The 500th Fibonacci number is "
      ORDER_PP(8stringize(8to_lit(8fib(8nat(5,0,0)))))
      ".\n");
   return 0;
}

preprocessing the file we get the following result (after a rather long wait):

$ cpp -I../inc fibonacci.c 2>/dev/null | tail
  return fib_iter(n, 0, 1);
}
# 63 "fibonacci.c"
int main(void) {
   printf
     ("The 500th Fibonacci number is "
      "139423224561697880139724382870407283950070256587697307264108962948325571622863290691557658876222521294125"
      ".\n");
   return 0;
}

It's been awhile since I've done anything with batch files but I think that the following works:

find /c "string" file
if %errorlevel% equ 1 goto notfound
echo found
goto done
:notfound
echo notfound
goto done
:done

This is really a proof of concept; clean up as it suits your needs. The key is that find returns an errorlevel of 1 if string is not in file. We branch to notfound in this case otherwise we handle the found case.

In my case, I left out wrapper sub folder while copying gradle folder and got the same error.

Could not find or load main class org.gradle.wrapper.GradleWrapperMain

make sure you have the correct folder structure if you copy wrapper from other location.

+-- build.gradle
+-- gradle
¦   +-- wrapper
¦       +-- gradle-wrapper.jar
¦       +-- gradle-wrapper.properties
+-- gradlew
+-- gradlew.bat
+-- settings.gradle

You miss the from clause

SELECT *  from TCCAWZTXD.TCC_COIL_DEMODATA WHERE CURRENT_INSERTTIME  BETWEEN(CURRENT_TIMESTAMP)-5 minutes AND CURRENT_TIMESTAMP

Model.select(:rating).distinct

You can place most of <script> references at the end of <body>,
But If there are active components on your page which are using external scripts,
then their dependency (js files) should come before that (ideally in head tag).

Cast the datetime to a date, then GROUP BY using this syntax:

SELECT SUM(foo), DATE(mydate) FROM a_table GROUP BY DATE(a_table.mydate);

Or you can GROUP BY the alias as @orlandu63 suggested:

SELECT SUM(foo), DATE(mydate) DateOnly FROM a_table GROUP BY DateOnly;

Though I don't think it'll make any difference to performance, it is a little clearer.

Use Scalable DP

Although making a different layout for different screen sizes is theoretically a good idea, it can get very difficult to accommodate for all screen dimensions, and pixel densities. Having over 20+ different dimens.xml files as suggested in the above answers, is not easy to manage at all.

How To Use:

To use sdp:

1. Include implementation 'com.intuit.sdp:sdp-android:1.0.5' in your build.gradle,

2. Replace any dp value such as 50dp with a @dimen/50_sdp like so:

   <TextView
    android:layout_width="@dimen/_50sdp"
    android:layout_height="@dimen/_50sdp"
    android:text="Hello World!" />
   

How It Works:

sdp scales with the screen size because it is essentially a huge list of different dimens.xml for every possible dp value.

See It In Action:

Here it is on three devices with widely differing screen dimensions, and densities:

Note that the sdp size unit calculation includes some approximation due to some performance and usability constraints.

I'm the creator of Restangular.

You can take a look at this CRUD example to see how you can PUT/POST/GET elements without all that URL configuration and $resource configuration that you need to do. Besides it, you can then use nested resources without any configuration :).

Check out this plunkr example:

http://plnkr.co/edit/d6yDka?p=preview

You could also see the README and check the documentation here https://github.com/mgonto/restangular

If you need some feature that's not there, just create an issue. I usually add features asked within a week, as I also use this library for all my AngularJS projects :)

Hope it helps!

To complement the preexisting, helpful answers with guidance of when to use which approach and a performance comparison.

• Outside of a pipeline^[1], use (PSv3+):

  $objects.Name

  as demonstrated in rageandqq's answer, which is both syntactically simpler and much faster.

  • Accessing a property at the collection level to get its members' values as an array is called member enumeration and is a PSv3+ feature.

  • Alternatively, in PSv2, use the foreach statement, whose output you can also assign directly to a variable:

    $results = foreach ($obj in $objects) { $obj.Name }

  • If collecting all output from a (pipeline) command in memory first is feasible, you can also combine pipelines with member enumeration; e.g.:

     (Get-ChildItem -File | Where-Object Length -lt 1gb).Name
    

  • Tradeoffs:

    • Both the input collection and output array must fit into memory as a whole.
    • If the input collection is itself the result of a command (pipeline) (e.g., (Get-ChildItem).Name), that command must first run to completion before the resulting array's elements can be accessed.

• In a pipeline, in case you must pass the results to another command, notably if the original input doesn't fit into memory as a whole, use:

  $objects | Select-Object -ExpandProperty Name

  • The need for -ExpandProperty is explained in Scott Saad's answer (you need it to get only the property value).
  • You get the usual pipeline benefits of the pipeline's streaming behavior, i.e. one-by-one object processing, which typically produces output right away and keeps memory use constant (unless you ultimately collect the results in memory anyway).
  • Tradeoff:
    • Use of the pipeline is comparatively slow.

For small input collections (arrays), you probably won't notice the difference, and, especially on the command line, sometimes being able to type the command easily is more important.

Here is an easy-to-type alternative, which, however is the slowest approach; it uses simplified ForEach-Object syntax called an operation statement (again, PSv3+): ; e.g., the following PSv3+ solution is easy to append to an existing command:

$objects | % Name      # short for: $objects | ForEach-Object -Process { $_.Name }

The PSv4+ .ForEach() array method, more comprehensively discussed in this article, is yet another, well-performing alternative, but note that it requires collecting all input in memory first, just like member enumeration:

# By property name (string):
$objects.ForEach('Name')

# By script block (more flexibility; like ForEach-Object)
$objects.ForEach({ $_.Name })

• This approach is similar to member enumeration, with the same tradeoffs, except that pipeline logic is not applied; it is marginally slower than member enumeration, though still noticeably faster than the pipeline.

• For extracting a single property value by name (string argument), this solution is on par with member enumeration (though the latter is syntactically simpler).

• The script-block variant ({ ... }) allows arbitrary transformations; it is a faster - all-in-memory-at-once - alternative to the pipeline-based ForEach-Object cmdlet (%).

Note: The .ForEach() array method, like its .Where() sibling (the in-memory equivalent of Where-Object), always returns a collection (an instance of [System.Collections.ObjectModel.Collection[psobject]]), even if only one output object is produced.
By contrast, member enumeration, Select-Object, ForEach-Object and Where-Object return a single output object as-is, without wrapping it in a collection (array).

Comparing the performance of the various approaches

Here are sample timings for the various approaches, based on an input collection of 10,000 objects, averaged across 10 runs; the absolute numbers aren't important and vary based on many factors, but it should give you a sense of relative performance (the timings come from a single-core Windows 10 VM:

Important

• The relative performance varies based on whether the input objects are instances of regular .NET Types (e.g., as output by Get-ChildItem) or [pscustomobject] instances (e.g., as output by Convert-FromCsv).
  The reason is that [pscustomobject] properties are dynamically managed by PowerShell, and it can access them more quickly than the regular properties of a (statically defined) regular .NET type. Both scenarios are covered below.

• The tests use already-in-memory-in-full collections as input, so as to focus on the pure property extraction performance. With a streaming cmdlet / function call as the input, performance differences will generally be much less pronounced, as the time spent inside that call may account for the majority of the time spent.

• For brevity, alias % is used for the ForEach-Object cmdlet.

General conclusions, applicable to both regular .NET type and [pscustomobject] input:

• The member-enumeration ($collection.Name) and foreach ($obj in $collection) solutions are by far the fastest, by a factor of 10 or more faster than the fastest pipeline-based solution.

Conclusions:

Conclusions:

• Note how with [pscustomobject] input .ForEach('Name') by far outperforms the script-block based variant, .ForEach({ $_.Name }).

• Similarly, [pscustomobject] input makes the pipeline-based Select-Object -ExpandProperty Name faster, in Windows PowerShell virtually on par with .ForEach({ $_.Name }), but in PowerShell Core still about 50% slower.

• In short: With the odd exception of % Name, with [pscustomobject] the string-based methods of referencing the properties outperform the scriptblock-based ones.

You can use map() function:

a = list(map(lambda x: x - 13, a))

Just add this lines to your codes :

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

This should work:

msiexec /i "msi path" TARGETDIR="C:\myfolder" /qb

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

I had this issue but it was fixed easily by going to the Internet Information Services (IIS) Manager, double clicking Directory Browsing and clicking Enable.

In my case, I could access files directly but could not access folders.

This link says it better than I could and helped in my decision making. I usually opt for an int as a primary key, unless I have a specific need not to and I also let SQL server auto-generate/maintain this field unless I have some specific reason not to. In reality, performance concerns need to be determined based on your specific app. There are many factors at play here including but not limited to expected db size, proper indexing, efficient querying, and more. Although people may disagree, I think in many scenarios you will not notice a difference with either option and you should choose what is more appropriate for your app and what allows you to develop easier, quicker, and more effectively (If you never complete the app what difference does the rest make :).

P.S. I'm not sure why you would use a Composite PK or what benefit you believe that would give you.

Use a Border of height 1 and don't set the Width (i.e. Width = Auto, HorizontalAlignment = Stretch, the default)

lvalue means "left value" -- it should be assignable. You cannot change the value of text since it is an array, not a pointer.

Either declare it as char pointer (in this case it's better to declare it as const char*):

const char *text;
if(number == 2) 
    text = "awesome"; 
else 
    text = "you fail";

Or use strcpy:

char text[60];
if(number == 2) 
    strcpy(text, "awesome"); 
else 
    strcpy(text, "you fail");

robertsd's code is elegant, yet to make it future-proof, change the declaration of n to type long

In case you want a formula to avoid macro's, here is something that works up to column 702 inclusive

=IF(A1>26,CHAR(INT((A1-1)/26)+64),"")&CHAR(MOD(A1-1,26)+65)

where A1 is the cell containing the column number to be converted to letters.

No, not exactly. But it can inherit from a class and implement one or more interfaces.

Clear terminology is important when discussing concepts like this. One of the things that you'll see mark out Jon Skeet's writing, for example, both here and in print, is that he is always precise in the way he decribes things.

Attributes are also data members and properties of a class. They are Variables declared inside class.

You can call tesseract API function from C code:

#include <tesseract/baseapi.h>
#include <tesseract/ocrclass.h>; // ETEXT_DESC

using namespace tesseract;

class TessAPI : public TessBaseAPI {
    public:
    void PrintRects(int len);
};

...
TessAPI *api = new TessAPI();
int res = api->Init(NULL, "rus");
api->SetAccuracyVSpeed(AVS_MOST_ACCURATE);
api->SetImage(data, w0, h0, bpp, stride);
api->SetRectangle(x0,y0,w0,h0);

char *text;
ETEXT_DESC monitor;
api->RecognizeForChopTest(&monitor);
text = api->GetUTF8Text();
printf("text: %s\n", text);
printf("m.count: %s\n", monitor.count);
printf("m.progress: %s\n", monitor.progress);

api->RecognizeForChopTest(&monitor);
text = api->GetUTF8Text();
printf("text: %s\n", text);
...
api->End();

And build this code:

g++ -g -I. -I/usr/local/include -o _test test.cpp -ltesseract_api -lfreeimageplus

(i need FreeImage for picture loading)

A slave isn't a server, it's a client type application. Network clients (almost) never use a specific port. Instead, they ask the OS for a random free port. This works much better since you usually run clients on many machines where the current configuration isn't known in advance. This prevents thousands of "client wouldn't start because port is already in use" bug reports every day.

You need to tell the security department that the slave isn't a server but a client which connects to the server and you absolutely need to have a rule which says client:ANY -> server:FIXED. The client port number should be >= 1024 (ports 1 to 1023 need special permissions) but I'm not sure if you actually gain anything by adding a rule for this - if an attacker can open privileged ports, they basically already own the machine.

If they argue, then ask them why they don't require the same rule for all the web browsers which people use in your company.

The simplest way to do this is use a table alias when you are referring parent query table inside the sub query.

Example :

insert into xxx_tab (trans_id) values ((select max(trans_id)+1 from xxx_tab));

Change it to:

insert into xxx_tab (trans_id) values ((select max(P.trans_id)+1 from xxx_tab P));

this is one:

ls -l . | egrep -c '^-'

Note:

ls -1 | wc -l

Which means: ls: list files in dir

-1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

|: pipe output onto...

wc: "wordcount"

-l: count lines.

You can use the UNPIVOT function to convert the columns into rows:

select id, entityId,
  indicatorname,
  indicatorvalue
from yourtable
unpivot
(
  indicatorvalue
  for indicatorname in (Indicator1, Indicator2, Indicator3)
) unpiv;

Note, the datatypes of the columns you are unpivoting must be the same so you might have to convert the datatypes prior to applying the unpivot.

You could also use CROSS APPLY with UNION ALL to convert the columns:

select id, entityid,
  indicatorname,
  indicatorvalue
from yourtable
cross apply
(
  select 'Indicator1', Indicator1 union all
  select 'Indicator2', Indicator2 union all
  select 'Indicator3', Indicator3 union all
  select 'Indicator4', Indicator4 
) c (indicatorname, indicatorvalue);

Depending on your version of SQL Server you could even use CROSS APPLY with the VALUES clause:

select id, entityid,
  indicatorname,
  indicatorvalue
from yourtable
cross apply
(
  values
  ('Indicator1', Indicator1),
  ('Indicator2', Indicator2),
  ('Indicator3', Indicator3),
  ('Indicator4', Indicator4)
) c (indicatorname, indicatorvalue);

Finally, if you have 150 columns to unpivot and you don't want to hard-code the entire query, then you could generate the sql statement using dynamic SQL:

DECLARE @colsUnpivot AS NVARCHAR(MAX),
   @query  AS NVARCHAR(MAX)

select @colsUnpivot 
  = stuff((select ','+quotename(C.column_name)
           from information_schema.columns as C
           where C.table_name = 'yourtable' and
                 C.column_name like 'Indicator%'
           for xml path('')), 1, 1, '')

set @query 
  = 'select id, entityId,
        indicatorname,
        indicatorvalue
     from yourtable
     unpivot
     (
        indicatorvalue
        for indicatorname in ('+ @colsunpivot +')
     ) u'

exec sp_executesql @query;

You can use a controller function to filter.

function MoviesCtrl($scope) {

    $scope.movies = [{name:'Shrek', genre:'Comedy'},
                     {name:'Die Hard', genre:'Action'},
                     {name:'The Godfather', genre:'Drama'}];

    $scope.selectedGenres = ['Action','Drama'];

    $scope.filterByGenres = function(movie) {
        return ($scope.selectedGenres.indexOf(movie.genre) !== -1);
    };

}

HTML:

<div ng-controller="MoviesCtrl">
    <ul>
        <li ng-repeat="movie in movies | filter:filterByGenres">
            {{ movie.name }} {{ movie.genre }}
        </li>
    </ul>
</div>

Edit December 2018: Apple seem to have finally added a button for removing the app in certain situations, including apps that never went on sale (thanks to @iwill for pointing that out), basically making the below answer irrelevant.

Edit: turns out the deleted apps still appear in Xcode -> Organizer -> Archives and there is no way to delete them from there even if there are no archives! So more looks like a fake delete of sorts.

Currently (Edit: as of July 2016) there is no way of deleting your app if it never went on sale.

However, all information except for SKU can be edited and thus reused for a new app, including the app name, Bundle ID, icon, etc etc. Because SKU can be anything (some people say they use numbers 1, 2, 3 for example) then it shouldn't be a big deal to use something unrelated for your new app.

(Honestly though I'm hoping Apple will fix this soon. I almost hear some Apple devs finding excuses for not implementing it (you know, it will break the database and will kill innocent pandas) and some managers telling the devs to just frigging do it regardless.)

"I don't want to use a trigger or any other thing other than Hibernate itself to generate the value for my property"

In that case, how about creating an implementation of UserType which generates the required value, and configuring the metadata to use that UserType for persistence of the mySequenceVal property?

I'd like to expand on Obertklep's answer. In his example it is an NPM module called body-parser which is doing most of the work. Where he puts req.body.name, I believe he/she is using body-parser to get the contents of the name attribute(s) received when the form is submitted.

If you do not want to use Express, use querystring which is a built-in Node module. See the answers in the link below for an example of how to use querystring.

It might help to look at this answer, which is very similar to your quest.

content doesn't support HTML, only text. You should probably use javascript, jQuery or something like that.

Another problem with your code is " inside a " block. You should mix ' and " (class='headingDetail').

If content did support HTML you could end up in an infinite loop where content is added inside content.

Storm's answer is not correct. No hard feelings Storm, and apologies to the OP as I'm a bit late to the party here (wish I could have helped sooner, but I didn't run into the problem until today, or this stack overflow answer until I was figuring out a solution.)

The Visual C++ 2003 runtime was not available as a seperate download because it was included with the .NET 1.1 runtime.

If you install the .NET 1.1 runtime you will get msvcr71.dll installed, and in addition added to C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322.

The .NET 1.1 runtime is available here: http://www.microsoft.com/downloads/en/details.aspx?familyid=262d25e3-f589-4842-8157-034d1e7cf3a3&displaylang=en (23.1 MB)

If you are looking for a file that ends with a "P" such as msvcp71.dll, this indicates that your file was compiled against a C++ runtime (as opposed to a C runtime), in some situations I noticed these files were only installed when I installed the full SDK. If you need one of these files, you may need to install the full .NET 1.1 SDK as well, which is available here: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=9b3a2ca6-3647-4070-9f41-a333c6b9181d (106.2 MB)

After installing the SDK I now have both msvcr71.dll and msvcp71.dll in my System32 folder, and the application I'm trying to run (boomerang c++ decompiler) works fine without any missing DLL errors.

Also on a side note: be VERY aware of the difference between a Hotfix Update and a Regular Update. As noted in the linked KB932298 download (linked below by Storm): "Please be aware this Hotfix has not gone through full Microsoft product regression testing nor has it been tested in combination with other Hotfixes."

Hotfixes are NOT meant for general users, but rather users who are facing a very specific problem. As described in the article only install that Hotfix if you are have having specific daylight savings time issues with the rules that changed in 2007. -- Likely this was a pre-release for customers who "just couldn't wait" for the official update (probably for some business critical application) -- for regular users Windows Update should be all you need.

Thanks, and I hope this helps others who run into this issue!

If you want to make a new copy of an object or array, you must explicitly copy the properties of the object or the elements of the array, for example:

var arr1 = ['a','b','c'];
var arr2 = [];

for (var i=0; i < arr1.length; i++) {
   arr2[i] = arr1[i];
}

You can search for more information on Google about immutable primitive values and mutable object references.

I had this problem i.e. works fine when pasted into browser but 505s when done through java. It was simply the spaces that needed to be escaped/encoded.

s='foo bar baz'
a=( $s )
echo ${a[0]}
echo ${a[1]}
...

Arrays are in fact objects, so a reference is passed (the reference itself is passed by value, confused yet?). Quick example:

// assuming you allocated the list
public void addItem(Integer[] list, int item) {
    list[1] = item;
}

You will see the changes to the list from the calling code. However you can't change the reference itself, since it's passed by value:

// assuming you allocated the list
public void changeArray(Integer[] list) {
    list = null;
}

If you pass a non-null list, it won't be null by the time the method returns.

you can 'invoke' alternative bindings on Y this way:

...registered(X, Y), (Y=ct101; Y=ct102; Y=ct103).

Note the parenthesis are required to keep the correct execution control flow. The ;/2 it's the general or operator. For your restricted use you could as well choice the more idiomatic

...registered(X, Y), member(Y, [ct101,ct102,ct103]).

that on backtracking binds Y to each member of the list.

edit I understood with a delay your last requirement. If you want that Y match all 3 values the or is inappropriate, use instead

...registered(X, ct101), registered(X, ct102), registered(X, ct103).

or the more compact

...findall(Y, registered(X, Y), L), sort(L, [ct101,ct102,ct103]).

findall/3 build the list in the very same order that registered/2 succeeds. Then I use sort to ensure the matching.

...setof(Y, registered(X, Y), [ct101,ct102,ct103]).

setof/3 also sorts the result list

As a note here: SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext and SpringBeanAutowiringSupport.processInjectionBasedOnServletContext DOES NOT work with @Resource annotation. So, there are difference.

cout is in std namespace, you shall use std::cout in your code. And you shall not add using namespace std; in your header file, it's bad to mix your code with std namespace, especially don't add it in header file.

^\+[1-9]{1}[0-9]{7,11}$ 

The Regular Expression ^\+[1-9]{1}[0-9]{7,11}$ fails for "+290 8000" and similar valid numbers that are shorter than 8 digits.

The longest numbers could be something like 3 digit country code, 3 digit area code, 8 digit subscriber number, making 14 digits.

Microsoft Docs gives us two approaches.

Recommended HttpPost Edit code: Read and update

This is the same old way we used to do in previous versions of Entity Framework. and this is what Microsoft recommends for us.

Advantages

• Prevents overposting
• EFs automatic change tracking sets the Modified flag on the fields that are changed by form input.

Alternative HttpPost Edit code: Create and attach

an alternative is to attach an entity created by the model binder to the EF context and mark it as modified.

As mentioned in the other answer the read-first approach requires an extra database read, and can result in more complex code for handling concurrency conflicts.

Try this:

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);

That works fine for me.

As for the missing "http://" I'd just do something like this:

if (!url.startsWith("http://") && !url.startsWith("https://"))
   url = "http://" + url;

I would also probably pre-populate your EditText that the user is typing a URL in with "http://".

This seems to be due to a problem in the UITableViewController subclass template. It comes with a version of the prepareForSegue method that would require you to unwrap the segue.

Replace your current prepareForSegue function with:

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    if (segue.identifier == "Load View") {
        // pass data to next view
    }
}

This version implicitly unwraps the parameters, so you should be fine.

From the jQuery documentation:

As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements. Handlers are attached to the currently selected elements in the jQuery object, so those elements must exist at the point the call to .bind() occurs. For more flexible event binding, see the discussion of event delegation in .on() or .delegate().

http://api.jquery.com/bind/

1. Create a .gitignore file, so to do that, you just create any blank .txt file.

2. Then you have to change its name writing the following line on the cmd (where git.txt is the name of the file you've just created):

   rename git.txt .gitignore

3. Then you can open the file and write all the untracked files you want to ignore for good. For example, mine looks like this:

```

OS junk files
[Tt]humbs.db
*.DS_Store

#Visual Studio files
*.[Oo]bj
*.user
*.aps
*.pch
*.vspscc

There's a whole collection of useful .gitignore files by GitHub

4. Once you have this, you need to add it to your git repository just like any other file, only it has to be in the root of the repository.

5. Then in your terminal you have to write the following line:

   git config --global core.excludesfile ~/.gitignore_global

From oficial doc:

You can also create a global .gitignore file, which is a list of rules for ignoring files in every Git repository on your computer. For example, you might create the file at ~/.gitignore_global and add some rules to it.

Open Terminal. Run the following command in your terminal: git config --global core.excludesfile ~/.gitignore_global

If the respository already exists then you have to run these commands:

git rm -r --cached .
git add .
git commit -m ".gitignore is now working"

If the step 2 doesn´t work then you should write the hole route of the files that you would like to add.

If you want a random number, use a random number library. If you want a unique identifier with effectively 0.00...many more 0s here...001% chance of collision, you should use UUIDv1. See Nick's post for UUIDv3 and v5.

UUIDv1 is NOT secure. It isn't meant to be. It is meant to be UNIQUE, not un-guessable. UUIDv1 uses the current timestamp, plus a machine identifier, plus some random-ish stuff to make a number that will never be generated by that algorithm again. This is appropriate for a transaction ID (even if everyone is doing millions of transactions/s).

To be honest, I don't understand why UUIDv4 exists... from reading RFC4122, it looks like that version does NOT eliminate possibility of collisions. It is just a random number generator. If that is true, than you have a very GOOD chance of two machines in the world eventually creating the same "UUID"v4 (quotes because there isn't a mechanism for guaranteeing U.niversal U.niqueness). In that situation, I don't think that algorithm belongs in a RFC describing methods for generating unique values. It would belong in a RFC about generating randomness. For a set of random numbers:

chance_of_collision = 1 - (set_size! / (set_size - tries)!) / (set_size ^ tries)

While using formControl, you have to import ReactiveFormsModule to your imports array.

Example:

import {FormsModule, ReactiveFormsModule} from '@angular/forms';

@NgModule({
  imports: [
    BrowserModule,
    FormsModule,
    ReactiveFormsModule,
    MaterialModule,
  ],
  ...
})
export class AppModule {}

The scheme is correct, User.ID must be the primary key of User, Job.ID should be the primary key of Job and Job.UserID should be a foreign key to User.ID. Also, your commands appear to be syntactically correct.

So what could be wrong? I believe you have at least a Job.UserID which doesn't have a pair in User.ID. For instance, if all values of User.ID are: 1,2,3,4,6,7,8 and you have a value of Job.UserID of 5 (which is not among 1,2,3,4,6,7,8, which are the possible values of UserID), you will not be able to create your foreign key constraint. Solution:

delete from Job where UserID in (select distinct User.ID from User);

will delete all jobs with nonexistent users. You might want to migrate these to a copy of this table which will contain archive data.

Post.find().sort({date:-1}, function(err, posts){
});

Should work as well

EDIT:

You can also try using this if you get the error sort() only takes 1 Argument :

Post.find({}, {
    '_id': 0,    // select keys to return here
}, {sort: '-date'}, function(err, posts) {
    // use it here
});

Using params allows you to call the function with no arguments. Without params:

static public int addTwoEach(int[] args)
{
    int sum = 0;

    foreach (var item in args)
    {
        sum += item + 2;
    }

    return sum;
}

addtwoEach(); // throws an error

Compare with params:

static public int addTwoEach(params int[] args)
{
    int sum = 0;

    foreach (var item in args)
    {
        sum += item + 2;
    }

    return sum;
}

addtwoEach(); // returns 0

Generally, you can use params when the number of arguments can vary from 0 to infinity, and use an array when numbers of arguments vary from 1 to infinity.

This is what events are for.

HTMLInputElementObject.addEventListener('input', function (evt) {
    something(this.value);
});

Take note of what is printed for x. You are trying to convert an array (basically just a list) into an int. length-1 would be an array of a single number, which I assume numpy just treats as a float. You could do this, but it's not a purely-numpy solution.

EDIT: I was involved in a post a couple of weeks back where numpy was slower an operation than I had expected and I realised I had fallen into a default mindset that numpy was always the way to go for speed. Since my answer was not as clean as ayhan's, I thought I'd use this space to show that this is another such instance to illustrate that vectorize is around 10% slower than building a list in Python. I don't know enough about numpy to explain why this is the case but perhaps someone else does?

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

time_start = datetime.datetime.now()

# My original answer
def f(x):
    rebuilt_to_plot = []
    for num in x:
        rebuilt_to_plot.append(np.int(num))
    return rebuilt_to_plot

for t in range(10000):
    x = np.arange(1, 15.1, 0.1)
    plt.plot(x, f(x))

time_end = datetime.datetime.now()

# Answer by ayhan
def f_1(x):
    return np.int(x)

for t in range(10000):
    f2 = np.vectorize(f_1)
    x = np.arange(1, 15.1, 0.1)
    plt.plot(x, f2(x))

time_end_2 = datetime.datetime.now()

print time_end - time_start
print time_end_2 - time_end

Try this, I hope it helps you.

mysqli_connect(): (HY000/2002): No such file or directory

I was facing same issue on debian9 VM, I tried to restart MySQL but it didn't solve the issue, after that I increased the RAM (I was reduced) and it worked.

I have just discovered a plugin on JSFiddle. Two possible alternatives : 1 single input OR 3 inputs, but looks like a single one... (use Tab key to go to the next input)

[link]http://jsfiddle.net/davidelrizzo/c8ASE/ It seems interesting !

So personally I really hate NSNotFound but understand its necessity.

But some people may not understand the complexities of comparing against NSNotFound

For example, this code:

- (BOOL)doesString:(NSString*)string containString:(NSString*)otherString {
    if([string rangeOfString:otherString].location != NSNotFound)
        return YES;
    else
        return NO;
}

has its problems:

1) Obviously if otherString = nil this code will crash. a simple test would be:

NSLog(@"does string contain string - %@", [self doesString:@"hey" containString:nil] ? @"YES": @"NO");

results in !! CRASH !!

2) What is not so obvious to someone new to objective-c is that the same code will NOT crash when string = nil. For example, this code:

NSLog(@"does string contain string - %@", [self doesString:nil containString:@"hey"] ? @"YES": @"NO");

and this code:

NSLog(@"does string contain string - %@", [self doesString:nil containString:nil] ? @"YES": @"NO");

will both result in

does string contains string - YES

Which is clearly NOT what you want.

So the better solution that I believe works is to use the fact that rangeOfString returns the length of 0 so then a better more reliable code is this:

- (BOOL)doesString:(NSString*)string containString:(NSString*)otherString {
    if(otherString && [string rangeOfString:otherString].length)
        return YES;
    else
        return NO;
}

OR SIMPLY:

- (BOOL)doesString:(NSString*)string containString:(NSString*)otherString {
    return (otherString && [string rangeOfString:otherString].length);
}

which will for cases 1 and 2 will return

does string contains string - NO

That's my 2 cents ;-)

Please check out my Gist for more helpful code.

Gwerder's solution wont work because hash = hmac.read(); happens before the stream is done being finalized. Thus AngraX's issues. Also the hmac.write statement is un-necessary in this example.

Instead do this:

var crypto    = require('crypto');
var hmac;
var algorithm = 'sha1';
var key       = 'abcdeg';
var text      = 'I love cupcakes';
var hash;

hmac = crypto.createHmac(algorithm, key);

// readout format:
hmac.setEncoding('hex');
//or also commonly: hmac.setEncoding('base64');

// callback is attached as listener to stream's finish event:
hmac.end(text, function () {
    hash = hmac.read();
    //...do something with the hash...
});

More formally, if you wish, the line

hmac.end(text, function () {

could be written

hmac.end(text, 'utf8', function () {

because in this example text is a utf string

Some Google services do not like to be used to much. Quite recently my account was locked because of script, which was sending two e-mails per second to the same user. Google considered it as a spam. So using sleep here is also justified to prevent such situations.
