For a single string String.ToCharArray should be used

string str = "One";
var charArray = str.ToCharArray();

For an array of strings

string[] arrayStrings = { "One", "Two", "Three" };
var charArrayList = arrayStrings.Select(str => str.ToCharArray()).ToList();

For a single character from a single string:

string str = "One";
var ch = str[0]; // means 'O'

You can also face problems if a subdirectory itself is a git repository - ie .has a .git directory - check with ls -a.

To remove go to the subdirectory and rm .git -rf.

Its important to mention that once in 4-5 years this method might give a 1 second error, becase of a leap-second (http://www.nist.gov/pml/div688/leapseconds.cfm), and the correct formula for that day would be

(24*60*60 + 1) * 1000

There is a question Are leap seconds catered for by Calendar? and the answer is no.

So, if You're designing super time-dependant software, be careful about this formula.

Use This code

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
void main(){
char a[10];
clrscr();
gets(a);
int i,length=0;
for(i=0;a[i]!='\0';i++)
length+=1;
for(i=0;i<length;i++){
a[i]=a[i]^32;
}
printf("%s",&a);
getch();
}

Significant differences that have not really been adequately mentioned here:

• map keeps iterators to all elements stable, in C++17 you can even move elements from one map to the other without invalidating iterators to them (and if properly implemented without any potential allocation).
• map timings for single operations are typically more consistent since they never need large allocations.
• unordered_map using std::hash as implemented in the libstdc++ is vulnerable to DoS if fed with untrusted input (it uses MurmurHash2 with a constant seed - not that seeding would really help, see https://emboss.github.io/blog/2012/12/14/breaking-murmur-hash-flooding-dos-reloaded/).
• Being ordered enables efficient range searches, e.g. iterate over all elements with key = 42.

Swift 4:

To add an overlay, or the popup view You can also use the Container View with which you get a free View Controller ( you get the Container View from the usual object palette/library)

Steps:

1. Have a View (ViewForContainer in the pic) that holds this Container View, to dim it when the contents of Container View are displayed. Connect the outlet inside the first View Controller

2. Hide this View when 1st VC loads

3. Unhide when Button is clicked

4. To dim this View when the Container View content is displayed, set the Views Background to Black and opacity to 30%

You will get this effect when you click on the Button

In registration/login.html (nested within templates folder) if you insert the following line, the page will render like Django's original admin login page:

{% include "admin/login.html" %}

Note: The file should contain above lines only.

std::string::data would seem to be sufficient and most efficient. If you want to have non-const memory to manipulate (strange for encryption) you can copy the data to a buffer using memcpy:

unsigned char buffer[mystring.length()];
memcpy(buffer, mystring.data(), mystring.length());

STL fanboys would encourage you to use std::copy instead:

std::copy(mystring.begin(), mystring.end(), buffer);

but there really isn't much of an upside to this. If you need null termination use std::string::c_str() and the various string duplication techniques others have provided, but I'd generally avoid that and just query for the length. Particularly with cryptography you just know somebody is going to try to break it by shoving nulls in to it, and using std::string::data() discourages you from lazily making assumptions about the underlying bits in the string.

The fastest solution if you are not embedding js into your template is:

Put <script type="text/javascript"> window.CSRF_TOKEN = "{{ csrf_token }}"; </script> before your reference to script.js file in your template, then add csrfmiddlewaretoken into your data dictionary:

$.ajax({
            type: 'POST',
            url: somepathname + "do_it/",
            data: {csrfmiddlewaretoken: window.CSRF_TOKEN},
            success: function() {
                console.log("Success!");
            }
        })

If you do embed your js into the template, it's as simple as: data: {csrfmiddlewaretoken: '{{ csrf_token }}'}

All you need to do is pass in hours as the second parameter to moments diff function.

var a = moment([21,30,00], "HH:mm:ss")
var b = moment([09,30,00], "HH:mm:ss")
a.diff(b, 'hours') // 12

Docs: https://momentjs.com/docs/#/displaying/difference/

Example:

const dateFormat = "YYYY-MM-DD HH:mm:ss";_x000D_
// Get your start and end date/times_x000D_
const rightNow = moment().format(dateFormat);_x000D_
const thisTimeYesterday = moment().subtract(1, 'days').format(dateFormat);_x000D_
// pass in hours as the second parameter to the diff function_x000D_
const differenceInHours = moment(rightNow).diff(thisTimeYesterday, 'hours');_x000D_
_x000D_
console.log(`${differenceInHours} hours have passed since this time yesterday`);

<script _x000D_

</script>

EDIT: An unofficial Bootstrap Modal modification has been built to address responsive/mobile issues. This is perhaps the simplest and easiest way to remedy the problem.

There has since been a fix found in one of the issues you discussed earlier

in bootstrap-responsive.css

.modal { 
    position: fixed; 
    top: 3%; 
    right: 3%; 
    left: 3%; 
    width: auto; 
    margin: 0; 
}
.modal-body { 
    height: 60%; 
}

and in bootstrap.css

.modal-body { 
    max-height: 350px; 
    padding: 15px; 
    overflow-y: auto; 
    -webkit-overflow-scrolling: touch; 
 }

You can get back a commit after doing a reset --hard HEAD.

Make use of "git reflog" to check the history of the HEAD in the branch.

You will see your commit and its id here.

Do a

git reset {commit Id of the commit you want to bring back}

You can do something like:

s = np.random.normal(2, 3, 1000)
import matplotlib.pyplot as plt
count, bins, ignored = plt.hist(s, 30, density=True)
plt.plot(bins, 1/(3 * np.sqrt(2 * np.pi)) * np.exp( - (bins - 2)**2 / (2 * 3**2) ), 
linewidth=2, color='r')
plt.show()

Given that none of the answers here worked for me, I finally tracked down my issue connecting to Bitbucket (or Github, doesn't matter in this case) with ssh -vT [email protected].

In my case, the failure was due to using a DSA key instead of RSA, and apparently my SSH client no longer allows that.

debug1: Skipping ssh-dss key /c/Users/USER/.ssh/id_dsa for not in PubkeyAcceptedKeyTypes

The solution was to add this to .ssh/config:

Host *
    PubkeyAcceptedKeyTypes +ssh-dss

This elegantly appends the ssh-dss key type to all existing accepted public key types and after this was done, git can now ssh into Bitbucket no problem.

Your if statement is always false and T gets initialized only if a condition is met, so the code doesn't reach the point where T gets a value (and by that, gets defined/bound). You should introduce the variable in a place that always gets executed.

Try:

def temp_sky(lreq, breq):
    T = <some_default_value> # None is often a good pick
    for line in tfile:
        data = line.split()
        if abs(float(data[0])-lreq) <= 0.1 and abs(float(data[1])-breq) <= 0.1:            
            T = data[2]
    return T

You will need these imports...

import javax.servlet.*;
import javax.servlet.http.*;

And, if you're using Maven, you'll also need this in the dependencies block of the pom.xml file in your project's base directory.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>

Then the above-listed fix by Jason will work:

@ResponseBody
    public ResponseEntity<Boolean> saveData(HttpServletRequest request,
        HttpServletResponse response, Model model){
        String jsonString = request.getParameter("json");
    }

Traditionally PHP has been tolerant to bad practice and failures in code, which makes debugging quite hard. The problem in this specific case is that both mysqli and PDO by default don't tell you, when a query failed and just return FALSE. (I will not talk about the depricated mysql extention. The support for prepared statements is reason anough to switch either to PDO or mysqli.) But you can change the default behavior of PHP to always throw exceptions when a query fails.

For PDO: Use $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

error_reporting(E_ALL);

$pdo = new PDO("mysql:host=localhost;dbname=test", "test","");
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$result = $pdo->query('select emal from users');
$data = $result->fetchAll();

This will show you the following:

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'emal' in 'field list'' in E:\htdocs\test\mysql_errors\pdo.php on line 8

PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'emal' in 'field list' in E:\htdocs\test\mysql_errors\pdo.php on line 8

As you see, it tells you exactly, what is wrong with the query, and where to fix it in your code.

Without $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); you will get

Fatal error: Call to a member function fetchAll() on boolean in E:\htdocs\test\mysql_errors\pdo.php on line 9

For mysqli: Use mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

error_reporting(E_ALL);

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli('localhost', 'test', '', 'test');

$result = $mysqli->query('select emal from users');
$data = $result->fetch_all();

You will get

Fatal error: Uncaught exception 'mysqli_sql_exception' with message 'Unknown column 'emal' in 'field list'' in E:\htdocs\test\mysql_errors\mysqli.php on line 8

mysqli_sql_exception: Unknown column 'emal' in 'field list' in E:\htdocs\test\mysql_errors\mysqli.php on line 8

Without mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT); you only get

Fatal error: Call to a member function fetch_all() on boolean in E:\htdocs\test\mysql_errors\mysqli.php on line 10

Of course, you could manually check the MySQL errors. But I would go crazy if I had to do that every time I made a typo - or worse - every time I want to query the database.

/^[a-z0-9]+$/i

^         Start of string
[a-z0-9]  a or b or c or ... z or 0 or 1 or ... 9
+         one or more times (change to * to allow empty string)
$         end of string    
/i        case-insensitive

Update (supporting universal characters)

if you need to this regexp supports universal character you can find list of unicode characters here.

for example: /^([a-zA-Z0-9\u0600-\u06FF\u0660-\u0669\u06F0-\u06F9 _.-]+)$/

this will support persian.

Unfortunately this is invalid HTML. An ID has to be unique in the whole HTML file.

When you use Javascript's document.getElementById() it depends on the browser, which element it will return, mostly it's the first with a given ID.

You will have no other chance as to re-assign your IDs, or alternatively using the class attribute.

I found @naota's solution useful, and extended it to use dates as well

//taken from StackOverflow:
//https://stackoverflow.com/questions/3880615/how-can-i-determine-whether-a-given-string-represents-a-date
function isDate(val) {
    var d = new Date(val);
    return !isNaN(d.valueOf());
}

var getVal = function(elm, n){
  var v = $(elm).children('td').eq(n).text().toUpperCase();
  if($.isNumeric(v)){
    v = parseFloat(v,10);
    return v;
  }
  if (isDate(v)) {
    v = new Date(v);
    return v;
  }
  return v;
}

Because JSON has a string data type (which is practically anything between " and "). It does not have a data type that matches something

So, this is definitely not the "shorter" version - and one might digress if "shortest" and "Pythonic" are actually compatible.

But if one needs this pattern often, just put the logic in to a 10-liner generator - and get any meta-data related to an element's position directly on the for call. Another advantage here is that it will work wit an arbitrary iterable, not only Sequences.

_sentinel = object()

def iter_check_last(iterable):
    iterable = iter(iterable)
    current_element = next(iterable, _sentinel)
    while current_element is not _sentinel:
        next_element = next(iterable, _sentinel)
        yield (next_element is _sentinel, current_element)
        current_element = next_element

In [107]: for is_last, el in iter_check_last(range(3)):
     ...:     print(is_last, el)
     ...: 
     ...: 
False 0
False 1
True 2

My situation was something akin to:

switch (text) {
  case SOME_CONSTANT || ANOTHER_CONSTANT:
    console.log('Case 1 entered');

  break;

  case THIRD_CONSTANT || FINAL_CONSTANT:
    console.log('Case 2 entered');

  break;

  default:
    console.log('Default entered');
}

The default case always entered. If you're running into a similar multi-case switch statement issue, you're looking for this:

switch (text) {
  case SOME_CONSTANT:
  case ANOTHER_CONSTANT:
    console.log('Case 1 entered');

  break;

  case THIRD_CONSTANT:
  case FINAL_CONSTANT:
    console.log('Case 2 entered');

  break;

  default:
    console.log('Default entered');
}

Over time, we might have a really long list of branches.

While some of the other solutions are great, Here is what I do (simplified from Jacob's answer):

git branch | grep \*

Now,

git status

works, but only If there are any local changes

System.Diagnostics.Process.Start( "notepad.exe", "text.txt");

int val = b? 1 : 0;

So to make your expression work, changing && for -a will do the trick.

It is correct like this:

 if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
 then  ....

or like

 if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
 then  ....

or even

 if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
 then  ....

You can find further details in this question bash : Multiple Unary operators in if statement and some references given there like What is the difference between test, [ and [[ ?.

Make Executable your jar and after that double click on it on Mac OS then it works successfully.

sudo chmod +x filename.jar

Try this, I hope this works.

git checkout branch_name file_name

Example:

git checkout master App.java

This will not work if your branch name has a period in it.

git checkout "fix.june" alive.html
error: pathspec 'fix.june' did not match any file(s) known to git.

You can use this simple plugin to add scrollUp and scrollDown to your jQuery

https://github.com/phpust/JQueryScrollDetector

var lastScrollTop = 0;
var action = "stopped";
var timeout = 100;
// Scroll end detector:
$.fn.scrollEnd = function(callback, timeout) {    
      $(this).scroll(function(){
        // get current scroll top 
        var st = $(this).scrollTop();
        var $this = $(this);
        // fix for page loads
        if (lastScrollTop !=0 )
        {
            // if it's scroll up
            if (st < lastScrollTop){
                action = "scrollUp";
            } 
            // else if it's scroll down
            else if (st > lastScrollTop){
                action = "scrollDown";
            }
        }
        // set the current scroll as last scroll top
        lastScrollTop = st;
        // check if scrollTimeout is set then clear it
        if ($this.data('scrollTimeout')) {
          clearTimeout($this.data('scrollTimeout'));
        }
        // wait until timeout done to overwrite scrolls output
        $this.data('scrollTimeout', setTimeout(callback,timeout));
    });
};

$(window).scrollEnd(function(){
    if(action!="stopped"){
        //call the event listener attached to obj.
        $(document).trigger(action); 
    }
}, timeout);

The other answers are excellent and I just want to provide a straight forward answer to this. Just limiting to jQuery asynchronous calls

All ajax calls (including the $.get or $.post or $.ajax) are asynchronous.

Considering your example

var outerScopeVar;  //line 1
$.post('loldog', function(response) {  //line 2
    outerScopeVar = response;
});
alert(outerScopeVar);  //line 3

The code execution starts from line 1, declares the variable and triggers and asynchronous call on line 2, (i.e., the post request) and it continues its execution from line 3, without waiting for the post request to complete its execution.

Lets say that the post request takes 10 seconds to complete, the value of outerScopeVar will only be set after those 10 seconds.

To try out,

var outerScopeVar; //line 1
$.post('loldog', function(response) {  //line 2, takes 10 seconds to complete
    outerScopeVar = response;
});
alert("Lets wait for some time here! Waiting is fun");  //line 3
alert(outerScopeVar);  //line 4

Now when you execute this, you would get an alert on line 3. Now wait for some time until you are sure the post request has returned some value. Then when you click OK, on the alert box, next alert would print the expected value, because you waited for it.

In real life scenario, the code becomes,

var outerScopeVar;
$.post('loldog', function(response) {
    outerScopeVar = response;
    alert(outerScopeVar);
});

All the code that depends on the asynchronous calls, is moved inside the asynchronous block, or by waiting on the asynchronous calls.

In Windows Forms, if your string is in a textbox, you can easily use this:

textBoxcsharp.SelectAll();
textBoxcsharp.Copy();
textBoxcsharp.DeselectAll();

In my case, Tile Image loaded from remote url and tilesloaded event was triggered before render the image.

I solved with following dirty way.

var tileCount = 0;
var options = {
    getTileUrl: function(coord, zoom) {
        tileCount++;
        return "http://posnic.com/tiles/?param"+coord;
    },
    tileSize: new google.maps.Size(256, 256),
    opacity: 0.5,
    isPng: true
};
var MT = new google.maps.ImageMapType(options);
map.overlayMapTypes.setAt(0, MT);
google.maps.event.addListenerOnce(map, 'tilesloaded', function(){
    var checkExist = setInterval(function() {
        if ($('#map_canvas > div > div > div:nth-child(1) > div:nth-child(1) > div:nth-child(1) > div:nth-child(2) > div > div').length === tileCount) {
            callyourmethod();
            clearInterval(checkExist);
        }
    }, 100); // check every 100ms
});

You only need <script></script> Tag that's it. <script type="text/javascript"></script> is not a valid HTML tag, so for best SEO practice use <script></script>

git diff revision_n revision_m

if revision_n and revision_m are successive commits then it outputs same as git show revision_m

Convert each character to its ASCII code, subtract the ASCII code for "a" and add 1. I'm deliberately leaving the code as an exercise.

This sounds like homework. If so, please tag it as such.

Also, this won't deal with upper case letters, since you didn't state any requirement to handle them, but if you need to then just lowercase the string before you start.

Oh, and this will only deal with the latin "a" through "z" characters without any accents, etc.

To do what most people would want, create a placeholder that isn't an actual line breaking character. Then you can actually combine the approaches for:

REPLACE(REPLACE(REPLACE(MyField, CHAR(13) + CHAR(10), 'something else'), CHAR(13), 'something else'), CHAR(10), 'something else')

This way you replace only once. The approach of:

REPLACE(REPLACE(MyField, CHAR(13), ''), CHAR(10), '')

Works great if you just want to get rid of the CRLF characters, but if you want a placeholder, such as

<br/>

or something, then the first approach is a little more accurate.

Since http proxy protocol is similar to raw http protocol, you can redirect desired traffic to your development server by telling firefox it's a proxy server.

two limitations:

A. this won't let you use https connections.

B. some frameworks (e,g: wordpress) don't like this method and redirect the request the wrong way

just copy the following code into a .pac file (enter your site domain and IP address, of course), and switch development/production just by changing proxy configuration.

function FindProxyForURL(url, host) {
    var prox4site = {
        "mysite.com":"PROXY 10.0.1.100:80",
        "www.mysite.com":"PROXY 10.0.1.100:80"
    }

    return prox4site[host] || "DIRECT";
}

ES6 Update:

As the first answer mentions, with ES6/Babel, you can now create multi-line strings simply by using backticks:

const htmlString = `Say hello to 
multi-line
strings!`;

Interpolating variables is a popular new feature that comes with back-tick delimited strings:

const htmlString = `${user.name} liked your post about strings`;

This just transpiles down to concatenation:

user.name + ' liked your post about strings'

Original ES5 answer:

Google's JavaScript style guide recommends to use string concatenation instead of escaping newlines:

Do not do this:

var myString = 'A rather long string of English text, an error message \
                actually that just keeps going and going -- an error \
                message to make the Energizer bunny blush (right through \
                those Schwarzenegger shades)! Where was I? Oh yes, \
                you\'ve got an error and all the extraneous whitespace is \
                just gravy.  Have a nice day.';

The whitespace at the beginning of each line can't be safely stripped at compile time; whitespace after the slash will result in tricky errors; and while most script engines support this, it is not part of ECMAScript.

Use string concatenation instead:

var myString = 'A rather long string of English text, an error message ' +
               'actually that just keeps going and going -- an error ' +
               'message to make the Energizer bunny blush (right through ' +
               'those Schwarzenegger shades)! Where was I? Oh yes, ' +
               'you\'ve got an error and all the extraneous whitespace is ' +
               'just gravy.  Have a nice day.';

Until PHP 5.3, const could not be used in the global scope. You could only use this from within a class. This should be used when you want to set some kind of constant option or setting that pertains to that class. Or maybe you want to create some kind of enum.

define can be used for the same purpose, but it can only be used in the global scope. It should only be used for global settings that affect the entire application.

An example of good const usage is to get rid of magic numbers. Take a look at PDO's constants. When you need to specify a fetch type, you would type PDO::FETCH_ASSOC, for example. If consts were not used, you'd end up typing something like 35 (or whatever FETCH_ASSOC is defined as). This makes no sense to the reader.

An example of good define usage is maybe specifying your application's root path or a library's version number.

I don't think you can, and CSS is supposed to describe how the page looks not what it does, so even if you could, it's not really how you should be using it.

Perhaps you should think about using JQuery to apply common functionality to your form components?

In C++11 you have raw string literals. Sort of like here-text in shells and script languages like Python and Perl and Ruby.

const char * vogon_poem = R"V0G0N(
             O freddled gruntbuggly thy micturations are to me
                 As plured gabbleblochits on a lurgid bee.
              Groop, I implore thee my foonting turlingdromes.   
           And hooptiously drangle me with crinkly bindlewurdles,
Or I will rend thee in the gobberwarts with my blurlecruncheon, see if I don't.

                (by Prostetnic Vogon Jeltz; see p. 56/57)
)V0G0N";

All the spaces and indentation and the newlines in the string are preserved.

These can also be utf-8|16|32 or wchar_t (with the usual prefixes).

I should point out that the escape sequence, V0G0N, is not actually needed here. Its presence would allow putting )" inside the string. In other words, I could have put

                "(by Prostetnic Vogon Jeltz; see p. 56/57)"

(note extra quotes) and the string above would still be correct. Otherwise I could just as well have used

const char * vogon_poem = R"( ... )";

The parens just inside the quotes are still needed.

you can also use this code

//test" class="btn btn-primary pull-right">

It's working fine for me by the following way -

public async Task<object> TestMethod(TestModel model)
    {
        try
        {
            var apicallObject = new
            {
                Id= model.Id,
                name= model.Name
            };

            if (apicallObject != null)
            {
                var bodyContent = JsonConvert.SerializeObject(apicallObject);
                using (HttpClient client = new HttpClient())
                {
                    var content = new StringContent(bodyContent.ToString(), Encoding.UTF8, "application/json");
                    content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
                    client.DefaultRequestHeaders.Add("access-token", _token); // _token = access token
                    var response = await client.PostAsync(_url, content); // _url =api endpoint url
                    if (response != null)
                    {
                        var jsonString = await response.Content.ReadAsStringAsync();

                        try
                        {
                            var result = JsonConvert.DeserializeObject<TestModel2>(jsonString); // TestModel2 = deserialize object
                        }
                        catch (Exception e){
                            //msg
                            throw e;
                        }
                    }
                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
        return null;
    }

I think a more flexible option would be to wrap the Text() with Align() like so:

Align(
  alignment: Alignment.center, // Align however you like (i.e .centerRight, centerLeft)
  child: Text("My Text"),
),

Using Center() seems to ignore TextAlign entirely on the Text widget. It will not align TextAlign.left or TextAlign.right if you try, it will remain in the center.

You can use Swift4 or Swift 5 bellow like:

let date = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"
let current_date = dateFormatter.string(from: date)
print("current_date-->",current_date)

output like:

2020-03-02

Original answer:

I too tried to change the support library to "23". When I changed the targetSdkVersion to 23, Android Studio reported the following error:

This support library should not use a lower version (22) than the targetSdkVersion (23)

I simply changed:

compile 'com.android.support:appcompat-v7:23.0.0'

to

compile 'com.android.support:appcompat-v7:+'

Although this fixed my issue, you should not use dynamic versions. After a few hours the new support repository was available and it is currently 23.0.1.

Pro tip:

You can use double quotes and create a ${supportLibVersion} variable for simplicity. Example:

ext {
    supportLibVersion = '23.1.1'
}

compile "com.android.support:appcompat-v7:${supportLibVersion}"
compile "com.android.support:design:${supportLibVersion}"
compile "com.android.support:palette-v7:${supportLibVersion}"
compile "com.android.support:customtabs:${supportLibVersion}"
compile "com.android.support:gridlayout-v7:${supportLibVersion}"

Java doesn't natively allow building of an exe, that would defeat its purpose of being cross-platform.

AFAIK, these are your options:

1. Make a runnable JAR. If the system supports it and is configured appropriately, in a GUI, double clicking the JAR will launch the app. Another option would be to write a launcher shell script/batch file which will start your JAR with the appropriate parameters

2. There also executable wrappers - see How can I convert my Java program to an .exe file?

You can also use lowercaseString and capitalizedString

For me, the problem was using svg images. I switched them to png and it worked.

byte messageDigest[] = algorithm.digest();
StringBuffer hexString = new StringBuffer();
for (int i = 0; i < messageDigest.length; i++) {
    String hexByte = Integer.toHexString(0xFF & messageDigest[i]);
    int numDigits = 2 - hexByte.length();
    while (numDigits-- > 0) {
        hexString.append('0');
    }
    hexString.append(hexByte);
}

this worked for me .

    const filterData = this.state.data2.filter(item=>((item.name.includes(text)) || (item.surname.includes(text)) || (item.email.includes(text)) || (item.userId === Number(text))) ) ;

select min(table.id), table.column1
from table 
group by table.column1

You won't face any terrible consequence, just the history will look kind of confusing.

You could change the commit message by doing

git commit --amend
git push --force-with-lease # (as opposed to --force, it doesn't overwrite others' work)

BUT this will override the remote history with yours, meaning that if anybody pulled that repo in the meanwhile, this person is going to be very mad at you...

Just do it if you are the only person accessing the repo.

Go to Menu Server and Click on Data Export. There you can select the table and select the option Dump Structure and Data' from the drop-down.

If you are using non-parallel direct path loads then consider and benchmark not dropping the indexes at all, particularly if the indexes only cover a minority of the columns. Oracle has a mechanism for efficient maintenance of indexes on direct path loads.

Otherwise, I'd also advise making the indexes unusable instead of dropping them. Less chance of accidentally not recreating an index.

After reading Byte Commander's answer, I want to introduce a tiny possible improvement:

You can generate a regexp that will match either n words, as long as your n is predetermined. For instance, if I want to match between 1 and 3 words, the regexp:

^([A-Z]+)(?:,([A-Z]+))?(?:,([A-Z]+))?$

will match the next sentences, with one, two or three capturing groups.

HELLO,LITTLE,WORLD
HELLO,WORLD
HELLO

You can see a fully detailed explanation about this regular expression on Regex101.

As I said, it is pretty easy to generate this regexp for any groups you want using your favorite language. Since I'm not much of a swift guy, here's a ruby example:

def make_regexp(group_regexp, count: 3, delimiter: ",")
  regexp_str = "^(#{group_regexp})"
  (count - 1).times.each do
    regexp_str += "(?:#{delimiter}(#{group_regexp}))?"
  end
  regexp_str += "$"
  return regexp_str
end

puts make_regexp("[A-Z]+")

That being said, I'd suggest not using regular expression in that case, there are many other great tools from a simple split to some tokenization patterns depending on your needs. IMHO, a regular expression is not one of them. For instance in ruby I'd use something like str.split(",") or str.scan(/[A-Z]+/)

Android Studio 0.8.10+ has introduced an incredibly useful tool called Memory Monitor.

What it's good for:

• Showing available and used memory in a graph, and garbage collection events over time.
• Quickly testing whether app slowness might be related to excessive garbage collection events.
• Quickly testing whether app crashes may be related to running out of memory.

Figure 1. Forcing a GC (Garbage Collection) event on Android Memory Monitor

You can have plenty good information on your app's RAM real-time consumption by using it.

'&' --> '&'

'<' --> '&lt;'

'>' --> '&gt;'

I usually do the following for my rails 4 projects:

In application.js

function onInit(callback){
    $(document).ready(callback);
    $(document).on('page:load', callback);
}

Then in the rest of the .js files, instead of using $(function (){}) I call onInit(function(){})

I'm a big fan of Bash job control, mainly the use of Control-Z and fg, especially if I'm doing development in a terminal. If I've got emacs open and need to compile, deploy, etc. I just Control-Z to suspend emacs, do what I need, and fg to bring it back. This keeps all of the emacs buffers intact and makes things much easier than re-launching whatever I'm doing.

Also another important note. You have to set android.permission.ACCESS_NETWORK_STATE in your AndroidManifest.xml for this to work.

_ how could I have found myself the information I needed in the online documentation?

You just have to read the documentation the the classes properly enough and you'll find all answers you are looking for. Check out the documentation on ConnectivityManager. The description tells you what to do.

SELECT COUNT(*) FROM information_schema.tables WHERE table_schema = 'database_name';

A more elegant way is to assign the whole array at once:

Sub PrintArray(Data, SheetName, StartRow, StartCol)

    Dim Rng As Range

    With Sheets(SheetName)
        Set Rng = .Range(.Cells(StartRow, StartCol), _
            .Cells(UBound(Data, 1) - LBound(Data, 1) + StartRow, _
            UBound(Data, 2) - LBound(Data, 2) + StartCol))
    End With
    Rng.Value2 = Data

End Sub

But watch out: it only works up to a size of about 8,000 cells. Then Excel throws a strange error. The maximum size isn't fixed and differs very much from Excel installation to Excel installation.

It's easy to do this like

private static boolean isNeg(T l) {
        return (Math.abs(l-1)>Math.abs(l));
 }

It is the directory from where you run the command to execute your batch file.

As mentioned in the above answers you can add the below command to your script to verify:

> set current_dir=%cd%
> echo %current_dir%  

The only difference between the RANK() and DENSE_RANK() functions is in cases where there is a “tie”; i.e., in cases where multiple values in a set have the same ranking. In such cases, RANK() will assign non-consecutive “ranks” to the values in the set (resulting in gaps between the integer ranking values when there is a tie), whereas DENSE_RANK() will assign consecutive ranks to the values in the set (so there will be no gaps between the integer ranking values in the case of a tie).

For example, consider the set {30, 30, 50, 75, 75, 100}. For such a set, RANK() will return {1, 1, 3, 4, 4, 6} (note that the values 2 and 5 are skipped), whereas DENSE_RANK() will return {1,1,2,3,3,4}.

$search_string = 4;
$original_array = [1,2,1,3,2,4,4,4,4,4,10];
$step1 = implode(",", $original_array); // convert original_array to string
$step2 = explode($search_string, $step1); // break step1 string into a new array using the search string as delimiter
$result = count($step2)-1; // count the number of elements in the resulting array, minus the first empty element
print_r($result); // result is 5

Here's what you need:

function mainfunc (){
    window[Array.prototype.shift.call(arguments)].apply(null, arguments);
}

The first argument is used as the function name and all of the remaining ones are used as arguments to the called function...

We're able to use the shift method to return and then delete the first value from the arguments array. Note that we've called it from the Array prototype since, strictly speaking, 'arguments' is not a real array and so doesn't inherit the shift method like a regular array would.

You can also call the shift method like this:

[].shift.call(arguments);

I don't see the benefit in aliasing out users tied to Schemas. Here is why....

Most people connect their user accounts to databases via roles initially, As soon as you assign a user to either the sysadmin, or the database role db_owner, in any form, that account is either aliased to the "dbo" user account, or has full permissions on a database. Once that occurs, no matter how you assign yourself to a scheme beyond your default schema (which has the same name as your user account), those dbo rights are assigned to those object you create under your user and schema. Its kinda pointless.....and just a namespace and confuses true ownership on those objects. Its poor design if you ask me....whomever designed it.

What they should have done is created "Groups", and thrown out schemas and role and just allow you to tier groups of groups in any combination you like, then at each tier tell the system if permissions are inherited, denied, or overwritten with custom ones. This would have been so much more intuitive and allowed DBA's to better control who the real owners are on those objects. Right now its implied in most cases the dbo default SQL Server user has those rights....not the user.

I came across the situation where I met a condition that broke the loop, however the code after the .each() function still executed. I then set a flag to "true" with an immediate check for the flag after the .each() function to ensure the code that followed was not executed.

$('.groupName').each(function() {
    if($(this).text() == groupname){
        alert('This group already exists');
        breakOut = true;
        return false;
    }
});
if(breakOut) {
    breakOut = false;
    return false;
} 

I would like to add that if the initial value comes from a binding from some parent element or 1.5 component, make sure that the proper type is passed. If using @ in binding, the variable passed will be string and if the options are eg. integers then the empty option will show up.

Either parse properly the value in init, or binding with < and not @ (less recommended for performance unless necessary).

** Update**: 11/19/2019

Microsoft has released a new version of the control 150.1400.0 in their Nuget library. My short testing shows that it works again in the forms designer where 150.1357.0 and 150.1358.0 did not. This includes being able to resize and modify the ReportViewer Tasks on the control itself.

** Update**: 8/18/2019

Removing the latest version and rolling back to 150.900.148.0 seems to work on multiple computers I'm using with VS2017 and VS2019.

You can roll back to 150.900.148 in the Nuget solution package manager. It works similarly to the previous versions. Use the drop down box to select the older version.

It may be easier to manually delete references to post 150.900 versions of ReportViewer and readd them than it is to fix them.

Remember to restart Visual Studio after changing the toolbox entry.

Update: 8/7/2019

A newer version of the ReportViewer control has been released, probably coinciding with Visual Studio 2019. I was working with V150.1358.0.

Following the directions in this answer gets the control in the designer's toolbox. But once dropped on the form it doesn't display. The control shows up below the form as a non-visual component.

This is working as designed according to Microsoft SQL BI support. This is the group responsible for the control.

While you still cannot interact with the control directly, these additional steps give a workaround so the control can be sized on the form. While now visible, the designer treats the control as if it didn't exist.

I've created a feedback request at the suggestion of Microsoft SQL BI support. Please consider voting on it to get Microsoft's attention.

Microsoft Azure Feedback page - Restore Designtime features of the WinForms ReportViewer Control

Additional steps:

• After adding the reportviewer to the WinForm
• Add a Panel Control to the WinForm.

• In the form's form.designer.cs file, add the Reportviewer control to the panel.

    // 
    // panel1
    // 
    this.panel1.Controls.Add(this.reportViewer1);
  

• Return to the form's designer, you should see the reportViewer on the panel

• In the Properties panel select the ReportViewer in the controls list dropdown
• Set the reportViewer's Dock property to Fill

Now you can position the reportViewer by actually interacting with the panel.

Update: Microsoft released a document on April 18, 2017 describing how to configure and use the reporting tool in Visual Studio 2017.

Visual Studio 2017 does not have the ReportViewer tool installed by default in the ToolBox. Installing the extension Microsoft Rdlc Report Designer for Visual Studio and then adding that to the ToolBox results in a non-visual component that appears below the form.

Microsoft Support had told me this is a bug, but as of April 21, 2017 it is "working as designed".

The following steps need to be followed for each project that requires ReportViewer.

• If you have ReportViewer in the Toolbox, remove it. Highlight, right-click and delete.
  • You will have to have a project with a form open to do this.

Edited 8/7/2019 - It looks like the current version of the RDLC Report Designer extension no longer interferes. You need this to actually edit the reports.

• If you have the Microsoft Rdlc Report Designer for Visual Studio extension installed, uninstall it.

• Close your solution and restart Visual Studio. This is a crucial step, errors will occur if VS is not restarted when switching between solutions.

• Open your solution.
• Open the NuGet Package Manager Console (Tools/NuGet Package Manager/Package Manager Console)

• At the PM> prompt enter this command, case matters.

  Install-Package Microsoft.ReportingServices.ReportViewerControl.WinForms

  You should see text describing the installation of the package.

Now we can temporarily add the ReportViewer tool to the tool box.

• Right-click in the toolbox and use Choose Items...

• We need to browse to the proper DLL that is located in the solutions Packages folder, so hit the browse button.

• In our example we can paste in the packages folder as shown in the text of Package Manager Console.

  C:\Users\jdoe\Documents\Projects\_Test\ReportViewerTest\WindowsFormsApp1\packages

• Then double click on the folder named Microsoft.ReportingServices.ReportViewerControl.Winforms.140.340.80

  The version number will probably change in the future.

• Then double-click on lib and again on net40.

• Finally, double click on the file Microsoft.ReportViewer.WinForms.dll

  You should see ReportViewer checked in the dialog. Scroll to the right and you will see the version 14.0.0.0 associated to it.

• Click OK.

ReportViewer is now located in the ToolBox.

• Drag the tool to the desired form(s).

• Once completed, delete the ReportViewer tool from the tool box. You can't use it with another project.

• You may save the project and are good to go.

Remember to restart Visual Studio any time you need to open a project with ReportViewer so that the DLL is loaded from the correct location. If you try and open a solution with a form with ReportViewer without restarting you will see errors indicating that the “The variable 'reportViewer1' is either undeclared or was never assigned.“.

If you add a new project to the same solution you need to create the project, save the solution, restart Visual Studio and then you should be able to add the ReportViewer to the form. I have seen it not work the first time and show up as a non-visual component.

When that happens, removing the component from the form, deleting the Microsoft.ReportViewer.* references from the project, saving and restarting usually works.

Use the title attribute, for example:

<div title="them's hoverin' words">hover me</div>

or:

<span title="them's hoverin' words">hover me</span>

<input type="hidden" id="date"/>
<script>document.getElementById("date").value = new Date().toJSON().slice(0,10)</script>

It is always C:\Windows\System32\WindowsPowershell\v1.0. It was left like that for backward compability is what I heard or read somewhere.

You may want to look at http://tug.ctan.org/tex-archive/macros/latex/contrib/float/ which allows you to define new floats using \newfloat

I say this because captions are usually applied to floats.

Straight ahead equations (those written with $ ... $, $$ ... $$, begin{equation}...) are in-line objects that do not support \caption.

This can be done using the following snippet just before \begin{document}

\usepackage{float}
\usepackage{aliascnt}
\newaliascnt{eqfloat}{equation}
\newfloat{eqfloat}{h}{eqflts}
\floatname{eqfloat}{Equation}

\newcommand*{\ORGeqfloat}{}
\let\ORGeqfloat\eqfloat
\def\eqfloat{%
  \let\ORIGINALcaption\caption
  \def\caption{%
    \addtocounter{equation}{-1}%
    \ORIGINALcaption
  }%
  \ORGeqfloat
}

and when adding an equation use something like

\begin{eqfloat}
\begin{equation}
f( x ) = ax + b
\label{eq:linear}
\end{equation}
\caption{Caption goes here}
\end{eqfloat}

Since seotweaks was originally created as a branch from master, merging it back in is a good idea. However if you are in a situation where one of your branches is not really a branch from master or your history is so different that you just want to obliterate the master branch in favor of the new branch that you've been doing the work on you can do this:

git push [-f] origin seotweaks:master

This is especially helpful if you are getting this error:

! [remote rejected] master (deletion of the current branch prohibited)

And you are not using GitHub and don't have access to the "Administration" tab to change the default branch for your remote repository. Furthermore, this won't cause down time or race conditions as you may encounter by deleting master:

git push origin :master

I made the following little scss mixin to build for all the bootstrap breakpoints...

With it I get .col-xs-divider-left or col-lg-divider-right etc.

Note: this uses v4-alpha bootstrap syntax...

@import 'variables';

$divider-height: 100%;

@mixin make-column-dividers($breakpoints: $grid-breakpoints) {
    // Common properties for all breakpoints
    %col-divider {
        position: absolute;
        content: " ";
        top: (100% - $divider-height)/2;
        height: $divider-height;
        width: $hr-border-width;
        background-color: $hr-border-color;
    }
    @each $breakpoint in map-keys($breakpoints) {
        .col-#{$breakpoint}-divider-right:before {
            @include media-breakpoint-up($breakpoint) {
                @extend %col-divider;
                right: 0;
            }
        }
        .col-#{$breakpoint}-divider-left:before {
            @include media-breakpoint-up($breakpoint) {
                @extend %col-divider;
                left: 0;
            }
        }
    }
}

You should execute script for install docker and launch it from command line:

brew install --cask docker
sudo -H pip3 install --upgrade pip3
open -a Docker
docker-compose ... 

after that docker-compose should work

I found this link helpful

$scope.loadSkillTags = function (query) {
var data = {qData: query};
   return SkillService.querySkills(data).then(function(response) {
   return response.data;
  });
 };

EDIT 2 (final) : According to the bootstrap 4 documentation, class="font-weight-bold" is what you are looking for.

EDIT : You can use class="font-weight-bold" as shown here (Bootstrap 4 alpha).

I kept the original answer below for clarity purposes.

I am posting this answer because this thread seems to have a lot of visitors, yet it had no proper solution to solve this issue. But there will be soon now a way with Bootstrap 4 :

As this GitHub pull request shows, you will just have to use the text-weight-normal, text-weight-bold and text-weight-italic classes.

This can maybe change until the official stable release. At this date of writing, this pull request is not merged yet in the alpha branch.

I will update this post once Bootstrap v4 has been released.

Created working Plunker for this. https://plnkr.co/edit/vR9aGoCwoOUL9tevIEen $('#console').append("<br/>"+$('#test_s :selected').text())

include.prepload.js file will have a line something like below. probably as the last line.

//# sourceMappingURL=include.prepload.js.map

Delete it and the error will go away.

Edit: As has been noted in the other answers, the standard actually guarantees that "the resulting value is the least unsigned integer congruent to the source integer (modulo 2n where n is the number of bits used to represent the unsigned type)". So even if your platform did not store signed ints as two's complement, the behavior would be the same.

Apparently your signed integer -62 is stored in two's complement (Wikipedia) on your platform:

62 as a 32-bit integer written in binary is

0000 0000 0000 0000 0000 0000 0011 1110

To compute the two's complement (for storing -62), first invert all the bits

1111 1111 1111 1111 1111 1111 1100 0001

then add one

1111 1111 1111 1111 1111 1111 1100 0010

And if you interpret this as an unsigned 32-bit integer (as your computer will do if you cast it), you'll end up with 4294967234 :-)

Use this : -- SQL Server 2008 or later

You should use Node.contains, since it's now standard and available in all browsers.

I'm new to JavaScript, but cant you just use: document.domain ?

Example:

<p id="ourdomain"></p>

<script>
var domainstring = document.domain;
document.getElementById("ourdomain").innerHTML = (domainstring);
</script>

Output:

domain.com

or

www.domain.com

Depending on what you use on your website.

states = "Alaska Alabama Arkansas American Samoa Arizona California Colorado"
states_list = states.split (' ')

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

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

Delete application IDs is allowed. Make sure you deleted all certificates, APNS certs and provisioning profiles associated with your application. Then go to Identitifies --> App IDs, select the application ID, Edit and Delete button should be enabled.

My issue was very particular: in my .env file, I put a comment in the line that had my api url:

API_URL=https://6ec1259f.ngrok.io #comment

I'd get the Invariant violation error when trying to log in/sign up, as the api url was wrong.

display: inline-flex does not make flex items display inline. It makes the flex container display inline. That is the only difference between display: inline-flex and display: flex. A similar comparison can be made between display: inline-block and display: block, and pretty much any other display type that has an inline counterpart.¹

There is absolutely no difference in the effect on flex items; flex layout is identical whether the flex container is block-level or inline-level. In particular, the flex items themselves always behave like block-level boxes (although they do have some properties of inline-blocks). You cannot display flex items inline; otherwise you don't actually have a flex layout.

It is not clear what exactly you mean by "vertically align" or why exactly you want to display the contents inline, but I suspect that flexbox is not the right tool for whatever you are trying to accomplish. Chances are what you're looking for is just plain old inline layout (display: inline and/or display: inline-block), for which flexbox is not a replacement; flexbox is not the universal layout solution that everyone claims it is (I'm stating this because the misconception is probably why you're considering flexbox in the first place).

¹ _{The differences between block layout and inline layout are outside the scope of this question, but the one that stands out the most is auto width: block-level boxes stretch horizontally to fill their containing block, whereas inline-level boxes shrink to fit their contents. In fact, it is for this reason alone you will almost never use display: inline-flex unless you have a very good reason to display your flex container inline.}

I came up with the following solution:

SELECT [Str], DecimalParsed = CASE 
WHEN ISNUMERIC([Str]) = 1 AND CHARINDEX('.', [Str])=0 AND LEN(REPLACE(REPLACE([Str], '-', ''), '+', '')) < 29 THEN CONVERT(decimal(38,10), [Str])
WHEN ISNUMERIC([Str]) = 1 AND (CHARINDEX('.', [Str])!=0 AND CHARINDEX('.', REPLACE(REPLACE([Str], '-', ''), '+', ''))<=29) THEN 
    CONVERT(decimal(38,10), 
            CASE WHEN LEN([Str]) - LEN(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE([Str], '0', ''), '1', ''), '2', ''), '3', ''), '4', ''), '5', ''), '6', ''), '7', ''), '8', ''), '9', '')) <= 38 
                 THEN [Str] 
                 ELSE SUBSTRING([Str], 1, 38 + LEN(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE([Str], '0', ''), '1', ''), '2', ''), '3', ''), '4', ''), '5', ''), '6', ''), '7', ''), '8', ''), '9', ''))) END)
ELSE NULL END
FROM TestStrToDecimal

I know it looks like an overkill and probably it is, but it works for me (checked both positive, negative, big and small numbers of different precision and scale - everything is converted to decimal(38,10) or NULL).

It is hard-coded to decimal(38,10) type, so if you need different precision, change the constants in the code (38, 10, 29).

How it works? The result is:

• if conversion is simple without overflow or precision loss (e.g. 123 or 123.456), then it just convert it.
• if number is not too big, but has too many digits after decimal point (e.g. 123.1234567890123456789012345678901234567890), then it trims the exceeding digits at the end keeping only 38 first digits.
• if number is too big and can't be converted to decimal without an overflow (e.g. 9876543210987654321098765432109876543210), then NULL is returned

each case is separate WHEN statement inthe code above.

Here are few examples of conversion:

For a precise answer to this question on "How to send data via intent from an Activity to Service", Is that you have to override the onStartCommand() method which is where you receive the intent object:

When you create a Service you should override the onStartCommand() method so if you closely look at the signature below, this is where you receive the intent object which is passed to it:

  public int onStartCommand(Intent intent, int flags, int startId)

So from an activity you will create the intent object to start service and then you place your data inside the intent object for example you want to pass a UserID from Activity to Service:

 Intent serviceIntent = new Intent(YourService.class.getName())
 serviceIntent.putExtra("UserID", "123456");
 context.startService(serviceIntent);

When the service is started its onStartCommand() method will be called so in this method you can retrieve the value (UserID) from the intent object for example

public int onStartCommand (Intent intent, int flags, int startId) {
    String userID = intent.getStringExtra("UserID");
    return START_STICKY;
}

Note: the above answer specifies to get an Intent with getIntent() method which is not correct in context of a service

The classic standpoint is to consider TCP as safe and UDP as unreliable.

But when TCP-IP protocols are used in safety critical applications, TCP is not recommended because it can stop on error for multiple reasons. Whereas UDP lets the application software deal with errors, retransmission timers, etc.

Moreover, TCP has more processing overhead than UDP.

Currently, UDP is used in aircraft controls and flight instruments, in the ARINC 664 standard also named AFDX (Avionics Full-Duplex Switched Ethernet). In ARINC 664, TCP is optional but UDP is used with the RTOS (real time operating systems) designed for the ARINC 653 standard (high reliability control software in civil aircrafts).

For more information about real time controls using IP and UDP in AFDX, you can read the pages 27 to 50 in http://www.afdx.com/pdf/AFDX_Training_October_2010_Full.pdf

Use cbind e.g.

df <- data.frame(b = runif(6), c = rnorm(6))
cbind(a = 0, df)

giving:

> cbind(a = 0, df)
  a         b          c
1 0 0.5437436 -0.1374967
2 0 0.5634469 -1.0777253
3 0 0.9018029 -0.8749269
4 0 0.1649184 -0.4720979
5 0 0.6992595  0.6219001
6 0 0.6907937 -1.7416569

Most developers of text editing programs misuse this name (auto-indent). The correct name is "maintain indentation". Auto-indent is what you actually want, but it is not implemented.

I would also like to see this feature in Notepad++.

You can use exec for that:

>>> foo = "bar"
>>> exec(foo + " = 'something else'")
>>> print bar
something else
>>> 

The answer to the question depends. There are 2 scenarios in this situation and you'll need to make a choice based on your appropriate scenario.

Scenario 1 - Critical script / Must needed script

In case the script you are using is important to load the website, it is recommended to be placed at the top of your HTML document i.e, <head>. Some examples include - application code, bootstrap, fonts, etc.

Scenario 2 - Less important / analytics scripts

There are also scripts used which do not affect the website's view. Such scripts are recommended to be loaded after all the important segments are loaded. And the answer to that will be bottom of the document i.e, bottom of your <body> before the closing tag. Some examples include - Google analytics, hotjar, etc.

Bonus - async / defer

You can also tell the browsers that the script loading can be done simultaneously with others and can be loaded based on the browser's choice using a defer / async argument in the script code.

eg. <script async src="script.js"></script>

Here is a list of converters (not updated since 2011):

• https://www2.sqlite.org/cvstrac/wiki?p=ConverterTools (or snapshot at archive.org)

i.e. you could do this:

1. Load data from source database using the ORM class.
2. Store data in memory or serialize to disk.
3. Store data into destination database using the ORM class.

INSERTED and DELETED are virtual tables. They need to be used in a FROM clause.

CREATE TRIGGER sampleTrigger
    ON database1.dbo.table1
    FOR DELETE
AS
    IF EXISTS (SELECT foo
               FROM database2.dbo.table2
               WHERE id IN (SELECT deleted.id FROM deleted)
               AND bar = 4)

The answers above are great. If you are in need of parsing all numbers out of a string that are nonconsecutive then the following may be of some help:

string input = "1-205-330-2342";
string result = Regex.Replace(input, @"[^\d]", "");
Console.WriteLine(result); // >> 12053302342

The main point is this:

col-lg-* col-md-* col-xs-* col-sm define how many columns will there be in these different screen sizes.

Example: if you want there to be two columns in desktop screens and in phone screens you put two col-md-6 and two col-xs-6 classes in your columns.

If you want there to be two columns in desktop screens and only one column in phone screens (ie two rows stacked on top of each other) you put two col-md-6 and two col-xs-12 in your columns and because sum will be 24 they will auto stack on top of each other, or just leave xs style out.

Selected date at the example is interesting. Example code block is:

Calendar c1 = GregorianCalendar.getInstance();
c1.set(2000, 1, 30);  //January 30th 2000
Date sDate = c1.getTime();

System.out.println(sDate);

and output Wed Mar 01 19:32:21 JST 2000.

When I first read the example i think that output is wrong but it is true:)

• Calendar.Month is starting from 0 so 1 means February.
• February last day is 28 so output should be 2 March.
• But selected year is important, it is 2000 which means February 29 so result should be 1 March.

If file filename.tar.gz gives this message: POSIX tar archive, the archive is a tar, not a GZip archive.

Unpack a tar without the z, it is for gzipped (compressed), only:

mv filename.tar.gz filename.tar # optional
tar xvf filename.tar

Or try a generic Unpacker like unp (https://packages.qa.debian.org/u/unp.html), a script for unpacking a wide variety of archive formats.

determine the file type:

$ file ~/Downloads/filename.tbz2
/User/Name/Downloads/filename.tbz2: bzip2 compressed data, block size = 400k

Personally, I would print them to a file using Perl or Python in the format

<COL_NAME>:  <COL_VAL>

for each row so that the file has as many lines as there are columns. Then I'd do a diff between the two files, assuming you are on Unix or compare them using some equivalent utilty on another OS. If you have multiple recordsets (i.e. more than one row), I would prepend to each file row and then the file would have NUM_DB_ROWS * NUM_COLS lines

You can use the npm-remote-ls module. You can install it globally:

npm install -g npm-remote-ls

And then call:

npm-remote-ls bower

Alternatively, [email protected] installed then you can use npx and avoid globally installing the command - just call:

npx npm-remote-ls bower

I know this is dated, but, you don't need to re-implement anything.

What I did was to negate the value on the property like this:

<!-- XAML code -->
<StackPanel Name="x"  Visibility="{Binding    Path=Specials, ElementName=MyWindow, Converter={StaticResource BooleanToVisibilityConverter}}"></StackPanel>    
<StackPanel Name="y"  Visibility="{Binding Path=NotSpecials, ElementName=MyWindow, Converter={StaticResource BooleanToVisibilityConverter}}"></StackPanel>        

....

//Code behind
public bool Specials
{
    get { return (bool) GetValue(SpecialsProperty); }
    set
    {
        NotSpecials= !value; 
        SetValue(SpecialsProperty, value);
    }
}

public bool NotSpecials
{
    get { return (bool) GetValue(NotSpecialsProperty); }
    set { SetValue(NotSpecialsProperty, value); }
}

And it works just fine!

Am I missing something?

Add div and it will solve the problem

To fix the port 80 problem do:

From cmd as administrator:

1. sc config http start= demand (you need a space after the equal sign and not before)
2. Reboot
3. Run the command (netsh http show servicestate) as administrator to check that the port 80 is in use

After you have run this command, you can disable http.sys as follows:

1. net stop http (stop the process)
2. Sc config http start= disabled (if you want to disable the service forever)

it works for me.

A much simpler solution:

<script language="javascript" src="http://maps.google.com/maps/api/js?v=3.2&sensor=false"></script>

and later in the code:

var online;
// check whether this function works (online only)
try {
  var x = google.maps.MapTypeId.TERRAIN;
  online = true;
} catch (e) {
  online = false;
}
console.log(online);

When not online the google script will not be loaded thus resulting in an error where an exception will be thrown.

A note about 64bit Windows which seems to trip up a few folks. If your app is running under 64bit Windows, you likely have to set the DWORD under [HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION] instead.

I think the best way to do this - if keeping the same font that is already assigned to the UILabel would be:

(using Swift)

label.font = label.font.fontWithSize(20)

(using Swift 3)

label.font = label.font.withSize(20)

Ideally I would set this in the viewDidLayoutSubviews method, as it doesn't need to change every time the view appears.

In Summary:

conda list   

(It will provide all the libraries along with version details).

And:

pip show tensorflow

(It gives complete library details).

This will convert n seconds into d days, h hours, m minutes, and s seconds.

from datetime import datetime, timedelta

def GetTime():
    sec = timedelta(seconds=int(input('Enter the number of seconds: ')))
    d = datetime(1,1,1) + sec

    print("DAYS:HOURS:MIN:SEC")
    print("%d:%d:%d:%d" % (d.day-1, d.hour, d.minute, d.second))

1) Update conda

Run the anaconda prompt as administrator

conda update -n base -c defaults conda

2) Create an environment for python new version say, 3.6

conda create --name py36 python=3.6

3) Activate the new environment

conda activate py36

4) Upgrade pip

pip install --upgrade pip

5) Install tensorflow

pip install https://testpypi.python.org/packages/db/d2/876b5eedda1f81d5b5734277a155fa0894d394a7f55efa9946a818ad1190/tensorflow-0.12.1-cp36-cp36m-win_amd64.whl

If it doesn't work

If you have problem with wheel at the environment location, or pywrap_tensorflow problem,

 pip install tensorflow --upgrade --force-reinstall

The S parameter does not do anything on its own.

/C      Carries out the command specified by string and then terminates  
/K      Carries out the command specified by string but remains  

Try something like this instead

Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)

You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.

Shell("perl a.pl c:\temp")

-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1

wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn

Look at the traceback:

Traceback (most recent call last):
  File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
    out = iter(out)
TypeError: 'bool' object is not iterable

Your code isn't iterating the value, but the code receiving it is.

The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)) or enclose it in a tuple ((False,)).

Always read the traceback: it's correct, and it's helpful.

I solved this issue by doing following:

1. Enter to system preferences -> mysql

2. Select "Initialize database" and enter a new root password selecting "Use Legacy Password Encryption".

3. Login into phpmyadmin with the new password.

You can use format like here,

  public static double getDoubleValue(String value,int digit){
    if(value==null){
        value="0";
     }
    double i=0;
     try {
         DecimalFormat digitformat = new DecimalFormat("#.##");
         digitformat.setMaximumFractionDigits(digit);
        return Double.valueOf(digitformat.format(Double.parseDouble(value)));

    } catch (NumberFormatException numberFormatExp) {
        return i;   
    }
}

There's an easier way, by extending an empty LatLngBounds rather than creating one explicitly from two points. (See this question for more details)

Should look something like this, added to your code:

//create empty LatLngBounds object
var bounds = new google.maps.LatLngBounds();
var infowindow = new google.maps.InfoWindow();    

for (i = 0; i < locations.length; i++) {  
  var marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i][1], locations[i][2]),
    map: map
  });

  //extend the bounds to include each marker's position
  bounds.extend(marker.position);

  google.maps.event.addListener(marker, 'click', (function(marker, i) {
    return function() {
      infowindow.setContent(locations[i][0]);
      infowindow.open(map, marker);
    }
  })(marker, i));
}

//now fit the map to the newly inclusive bounds
map.fitBounds(bounds);

//(optional) restore the zoom level after the map is done scaling
var listener = google.maps.event.addListener(map, "idle", function () {
    map.setZoom(3);
    google.maps.event.removeListener(listener);
});

This way, you can use an arbitrary number of points, and don't need to know the order beforehand.

Depending on the libc release it could be needed to set both SO_REUSEADDR and SO_REUSEPORT socket options as explained in socket(7) documentation :

   SO_REUSEPORT (since Linux 3.9)
          Permits multiple AF_INET or AF_INET6 sockets to be bound to an
          identical socket address.  This option must be set on each
          socket (including the first socket) prior to calling bind(2)
          on the socket.  To prevent port hijacking, all of the
          processes binding to the same address must have the same
          effective UID.  This option can be employed with both TCP and
          UDP sockets.

As this socket option appears with kernel 3.9 and raspberry use 3.12.x, it will be needed to set SO_REUSEPORT.

You can set theses two options before calling bind like this :

    int reuse = 1;
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, (const char*)&reuse, sizeof(reuse)) < 0)
        perror("setsockopt(SO_REUSEADDR) failed");

#ifdef SO_REUSEPORT
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEPORT, (const char*)&reuse, sizeof(reuse)) < 0) 
        perror("setsockopt(SO_REUSEPORT) failed");
#endif

Dealing with markup in floats is a non trivial task. In the English/American notation you format one thousand plus 46*10-2:

1,000.46

But in Germany you would change comma and point:

1.000,46

This makes it really hard guessing the right number in multi-language applications.
I strongly suggest using Zend_Measure of the Zend Framework for this task. This component will parse the string to a float by the users language.

Use:

/*
Creates an empty file, which can take all of the disk
space. Just specify the desired file size on the
command line.
*/

#include <windows.h>
#include <stdlib.h>

int main (int argc, char* ARGV[])
{
    int size;
    size = atoi(ARGV[1]);
    const char* full = "fulldisk.dsk";
    HANDLE hf = CreateFile(full,
                           GENERIC_WRITE,
                           0,
                           0,
                           CREATE_ALWAYS,
                           0,
                           0);
    SetFilePointer(hf, size, 0, FILE_BEGIN);
    SetEndOfFile(hf);
    CloseHandle(hf);
    return 0;
}

for some iPhone you have to put your viewport like this

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, shrink-to-fit=no, user-scalable=0" />

create the new name from scratch and delete the old one.

I believe the way to do this is $location.url('/RouteTo/Login');

Edit for Clarity

Say my route for my login view was /Login, I would say $location.url('/Login') to navigate to that route.

For locations outside of the Angular app (i.e. no route defined), plain old JavaScript will serve:

window.location = "http://www.my-domain.com/login"

Declare the following delay function:

var delay = (function () {
    var timer = 0;
    return function (callback, ms) {
        clearTimeout(timer);
        timer = setTimeout(callback, ms);
    };
})()

and then use it:

let $filter = $('#item-filter');
$filter.on('keydown', function () {
    delay(function () {            
        console.log('this will hit, once user has not typed for 1 second');            
    }, 1000);
});    

I assume you're using GCC. The standard solution would be to profile with gprof.

Be sure to add -pg to compilation before profiling:

cc -o myprog myprog.c utils.c -g -pg

I haven't tried it yet but I've heard good things about google-perftools. It is definitely worth a try.

Related question here.

A few other buzzwords if gprof does not do the job for you: Valgrind, Intel VTune, Sun DTrace.

If you set

-Djava.io.tmpdir=C:\temp

"Stdafx.h" is a precompiled header.It include file for standard system include files and for project-specific include files that are used frequently but are changed infrequently.which reduces compile time and Unnecessary Processing.

Precompiled Header stdafx.h is basically used in Microsoft Visual Studio to let the compiler know the files that are once compiled and no need to compile it from scratch. You can read more about it

There are no quotes in the return value, only in the default output from print() when you display the value. Try

> print(char[1], quote=FALSE)
[1] one

or

> cat(char[1], "\n")
one

to see the value without quotes.

Neither is "more correct". My personal preference is for the more concise form but either is fine. To me, life is too short to even think about arguing the toss over stuff like this.

This works for me:

function animateRotate (object,fromDeg,toDeg,duration){
    var dummy = $('<span style="margin-left:'+fromDeg+'px;">')
    $(dummy).animate({
        "margin-left":toDeg+"px"
    },{
        duration:duration,
        step: function(now,fx){
            $(object).css('transform','rotate(' + now + 'deg)');
        }
    });
};

A convenient function for saving plots is ggsave(), which can automatically guess the device type based on the file extension, and smooths over differences between devices. You save with a certain size and units like this:

ggsave("mtcars.png", width = 20, height = 20, units = "cm")

In R markdown, figure size can be specified by chunk:

```{r, fig.width=6, fig.height=4}  
plot(1:5)
```

I know this is a bit of an old thread but with pandas 19.02, you can do:

I had python 2.6 installed by default (Amazon EC2 AMI), but needed python2.7 plus some external packages for my application. Assuming you already installed python2.7 alongside with default python (2.6 in my case). Here is how to install pip and packages for non-default python2.7

Install pip for your python version:

curl -O https://bootstrap.pypa.io/get-pip.py
python27 get-pip.py

Use specific pip version to install packages:

pip2.7 install mysql-connector-python --allow-external mysql-connector-python

Javascript doesn't have it, as you point out.

A quick search came up with:

function strcmp ( str1, str2 ) {
    // http://kevin.vanzonneveld.net
    // +   original by: Waldo Malqui Silva
    // +      input by: Steve Hilder
    // +   improved by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)
    // +    revised by: gorthaur
    // *     example 1: strcmp( 'waldo', 'owald' );
    // *     returns 1: 1
    // *     example 2: strcmp( 'owald', 'waldo' );
    // *     returns 2: -1

    return ( ( str1 == str2 ) ? 0 : ( ( str1 > str2 ) ? 1 : -1 ) );
}

from http://kevin.vanzonneveld.net/techblog/article/javascript_equivalent_for_phps_strcmp/

Of course, you could just add localeCompare if needed:

if (typeof(String.prototype.localeCompare) === 'undefined') {
    String.prototype.localeCompare = function(str, locale, options) {
        return ((this == str) ? 0 : ((this > str) ? 1 : -1));
    };
}

And use str1.localeCompare(str2) everywhere, without having to worry wether the local browser has shipped with it. The only problem is that you would have to add support for locales and options if you care about that.

&& is new in C++11. int&& a means "a" is an r-value reference. && is normally only used to declare a parameter of a function. And it only takes a r-value expression. If you don't know what an r-value is, the simple explanation is that it doesn't have a memory address. E.g. the number 6, and character 'v' are both r-values. int a, a is an l-value, however (a+2) is an r-value. For example:

void foo(int&& a)
{
    //Some magical code...
}

int main()
{
    int b;
    foo(b); //Error. An rValue reference cannot be pointed to a lValue.
    foo(5); //Compiles with no error.
    foo(b+3); //Compiles with no error.

    int&& c = b; //Error. An rValue reference cannot be pointed to a lValue.
    int&& d = 5; //Compiles with no error.
}

Hope that is informative.

I would like to suggest new EmailAddressAttribute().IsValid(emailTxt) for additional validation before/after validating using RegEx

Remember EmailAddressAttribute is part of System.ComponentModel.DataAnnotations namespace.

Use string literal operator if C++14 (operator ""s)

using namespace std::string_literals;

throw std::exception("Could not load config file '"s + configfile + "'"s);

or define your own if in C++11. For instance

std::string operator ""_s(const char * str, std::size_t len) {
    return std::string(str, str + len);
}

Your throw statement will then look like this

throw std::exception("Could not load config file '"_s + configfile + "'"_s);

which looks nice and clean.

The standard Python library does not come with any tzinfo implementations at all. I've always considered this a surprising shortcoming of the datetime module.

The documentation for the tzinfo class does come with some useful examples. Look for the large code block at the end of the section.

For Logging your request and response you need an interceptor and also for setting the header you need an interceptor, Here's the solution for adding both the interceptor at once using retrofit 2.1

 public OkHttpClient getHeader(final String authorizationValue ) {
        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient okClient = new OkHttpClient.Builder()
                .addInterceptor(interceptor)
                .addNetworkInterceptor(
                        new Interceptor() {
                            @Override
                            public Response intercept(Interceptor.Chain chain) throws IOException {
                                Request request = null;
                                if (authorizationValue != null) {
                                    Log.d("--Authorization-- ", authorizationValue);

                                    Request original = chain.request();
                                    // Request customization: add request headers
                                    Request.Builder requestBuilder = original.newBuilder()
                                            .addHeader("Authorization", authorizationValue);

                                    request = requestBuilder.build();
                                }
                                return chain.proceed(request);
                            }
                        })
                .build();
        return okClient;

    }

Now in your retrofit object add this header in the client

Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(url)
                .client(getHeader(authorizationValue))
                .addConverterFactory(GsonConverterFactory.create())
                .build();

You can use the DataGridViewCell.Value Property to retrieve the value stored in a particular cell.

So to retrieve the value of the 'first' selected Cell and display in a MessageBox, you can:

MessageBox.Show(dataGridView1.SelectedCells[0].Value.ToString());

Using imgscalr – Java Image Scaling Library:

BufferedImage image =
     Scalr.resize(originalImage, Scalr.Method.BALANCED, newWidth, newHeight);

This is fast enough for me.

For GUI I'd say that the Object-Oriented Paradigma is very well suited. The Window is an Object, the Textboxes are Objects, and the Okay-Button is one too. On the other Hand stuff like String Processing can be done with much less overhead and therefore more straightforward with simple procedural paradigma.

I don't think it is a question of the language neither. You can write functional, procedural or object-oriented in almost any popular language, although it might be some additional effort in some.

for (i = 0; i < 16; i++)
{
    fscanf(myFile, "%d", &numberArray[i]);
}

This is attempting to read the whole string, "5623125698541159" into &numArray[0]. You need spaces between the numbers:

5 6 2 3 ...

There is no structure in numpy that allows you to append more data later.

Instead, numpy puts all of your data into a contiguous chunk of numbers (basically; a C array), and any resize requires allocating a new chunk of memory to hold it. Numpy's speed comes from being able to keep all the data in a numpy array in the same chunk of memory; e.g. mathematical operations can be parallelized for speed and you get less cache misses.

So you will have two kinds of solutions:

1. Pre-allocate the memory for the numpy array and fill in the values, like in JoshAdel's answer, or
2. Keep your data in a normal python list until it's actually needed to put them all together (see below)

images = []
for i in range(100):
    new_image = # pull image from somewhere
    images.append(new_image)
images = np.stack(images, axis=3)

Note that there is no need to expand the dimensions of the individual image arrays first, nor do you need to know how many images you expect ahead of time.

Therefore, before starting '$ sqlplus' on OS, run the followings:

• On Windows

  set NLS_LANG=AMERICAN_AMERICA.UTF8

• On Unix (Solaris and Linux, centos etc)

  export NLS_LANG=AMERICAN_AMERICA.UTF8

It would also be advisable to set env variable in your '.bash_profile' [on start up script]

This is the place where other ORACLE env variables (ORACLE_SID, ORACLE_HOME) are usually set.

just fyi - SQL Developer is good at displaying/handling non-English UTF8 characters.

Java references always point to an object. The object has a header that amongst other things identifies the concrete type (so casts can fail with ClassCastException). For arrays, the start of the object also includes the length, the data then follows immediately after in memory (technically an implementation is free to do what it pleases, but it would be daft to do anything else). So, you can;t have a reference that points somewhere into an array.

In C pointers point anywhere and to anything, and you can point to the middle of an array. But you can't safely cast or find out how long the array is. In D the pointer contains an offset into the memory block and length (or equivalently a pointer to the end, I can't remember what the implementation actually does). This allows D to slice arrays. In C++ you would have two iterators pointing to the start and end, but C++ is a bit odd like that.

So getting back to Java, no you can't. As mentioned, NIO ByteBuffer allows you to wrap an array and then slice it, but gives an awkward interface. You can of course copy, which is probably very much faster than you would think. You could introduce your own String-like abstraction that allows you to slice an array (the current Sun implementation of String has a char[] reference plus a start offset and length, higher performance implementation just have the char[]). byte[] is low level, but any class-based abstraction you put on that is going to make an awful mess of the syntax, until JDK7 (perhaps).

For the official CLI client "psql" see here. And "pgAdmin3" 1.10 (still in beta) has "pgScript".

The pack() method is defined in Window class in Java and it sizes the frame so that all its contents are at or above their preferred sizes.

Here is a hint Hint for gradle users without admin rights: add this line to your jaxb-task:

System.setProperty('javax.xml.accessExternalSchema', 'all')

it will look like this:

jaxb {
    System.setProperty('javax.xml.accessExternalSchema', 'all')
    xsdDir = "${project.name}/xsd"
    xjc {
        taskClassname = "com.sun.tools.xjc.XJCTask"
        args = ["-npa", "-no-header"]
    }
}

Two alternatives

1) Ordering the original array with sortInPlace

self.assignments.sortInPlace({ $0.order < $1.order })
self.printAssignments(assignments)

2) Using an alternative array to store the ordered array

var assignmentsO = [Assignment] ()
assignmentsO = self.assignments.sort({ $0.order < $1.order })
self.printAssignments(assignmentsO)

You mention you are using Pandas (in your title). If so, there is no need to use an external library, you can just use to_datetime

>>> pandas.to_datetime('today').normalize()
Timestamp('2015-10-14 00:00:00')

This will always return today's date at midnight, irrespective of the actual time, and can be directly used in pandas to do comparisons etc. Pandas always includes 00:00:00 in its datetimes.

Replacing today with now would give you the date in UTC instead of local time; note that in neither case is the tzinfo (timezone) added.

In pandas versions prior to 0.23.x, normalize may not have been necessary to remove the non-midnight timestamp.

In C# it doesn't matter. The two code samples you give are utterly equivalent. In the first example the C# compiler (or is it the CLR?) will construct an empty constructor and initialise the variables as if they were in the constructor (there's a slight nuance to this that Jon Skeet explains in the comments below). If there is already a constructor then any initialisation "above" will be moved into the top of it.

In terms of best practice the former is less error prone than the latter as someone could easily add another constructor and forget to chain it.

May be Method 3.

I always prefer to keep logic separate.

Predicate<Long> greaterThan100 = new Predicate<Long>() {
    @Override
    public boolean test(Long currentParameter) {
        return currentParameter > 100;
    }
};
        
List<Long> sourceLongList = Arrays.asList(1L, 10L, 50L, 80L, 100L, 120L, 133L, 333L);
List<Long> resultList = sourceLongList.parallelStream().filter(greaterThan100).collect(Collectors.toList());

I don't think using one printf statement to print string literals as seen above is a good programming practice; rather, one can use the piece of code below:

printf("name: %s\t",sp->name);
printf("args: %s\t",sp->args);
printf("value: %s\t",sp->value);
printf("arraysize: %s\t",sp->name); 

Nothing worked for me until I encoded the video properly. Try this guide for the correct handbrake settings: http://forum.handbrake.fr/viewtopic.php?f=7&t=9694

It doesn't because the href value is not sign_up.It is #sign_up. Try like below, You need to add "#" to indicate the id of the href value.

});

Each database's implementation but you can probably guess that they all solve common problems in more or less the same way. If you are using MSSQL have a look at the execution plan that is generated. You can do this by turning on the profiler and executions plans. This will give you a text version when you run the command.

I am not sure what version of MSSQL you are using but you can get a graphical one in SQL Server 2000 in the query analyzer. I am sure that this functionality is lurking some where in SQL Server Studio Manager in later versions.

Have a look at the exeuction plan. As far as possible avoid table scans unless of course your table is small in which case a table scan is faster than using an index. Read up on the different join operations that each different scenario produces.

In some scenarios, port can only be designated by the environment and is saved in a user environment variable. Below is how node.js apps work with it.

The process object is a global that provides information about, and control over, the current Node.js process. As a global, it is always available to Node.js applications without using require().

The process.env property returns an object containing the user environment.

An example of this object looks like:

{
  TERM: 'xterm-256color',
  SHELL: '/usr/local/bin/bash',
  USER: 'maciej',
  PATH: '~/.bin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin',
  PWD: '/Users/maciej',
  EDITOR: 'vim',
  SHLVL: '1',
  HOME: '/Users/maciej',
  LOGNAME: 'maciej',
  _: '/usr/local/bin/node'
}

For example,

terminal: set a new user environment variable, not permanently

export MY_TEST_PORT=9999

app.js: read the new environment variable from node app

console.log(process.env.MY_TEST_PORT)

terminal: run the node app and get the value

$ node app.js
9999

Assuming your file is named "myfile.ext"

If the file you're trying to load is not an R-script, for which you would use

source("myfile.ext")

you might try the readRDSfunction and assign it to a variable-name:

my.data <- readRDS("myfile.ext")

For me I had a typo and my remote branch didn't exist

Use git branch -a to list remote branches

You can't detect it with javascript.

Only events that do detect page unloading/closing are window.onbeforeunload and window.unload. Neither of these events can tell you the way that you closed the page.

Since vars passed through url are $_GET vars, you can use filter_input() function:

$id = filter_input(INPUT_GET, 'id', FILTER_SANITIZE_NUMBER_INT);
$othervar = filter_input(INPUT_GET, 'othervar', FILTER_SANITIZE_FULL_SPECIAL_CHARS);

It would store the values of each var and sanitize/validate them too.

Try this search and replace:

:%s/foo/bar/gc

Change each 'foo' to 'bar', but ask for confirmation first.

Press y or n to change or keep your text.

To have greater control of the track color (no API controlled alpha changes), I extended SwitchCompat and style the elements programmatically:

    public class CustomizedSwitch extends SwitchCompat {

    public CustomizedSwitch(Context context) {
        super(context);
        initialize(context);
    }

    public CustomizedSwitch(Context context, AttributeSet attrs) {
        super(context, attrs);
        initialize(context);
    }

    public CustomizedSwitch(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initialize(context);
    }

    public void initialize(Context context) {
        // DisplayMeasurementConverter is just a utility to convert from dp to px and vice versa
        DisplayMeasurementConverter displayMeasurementConverter = new DisplayMeasurementConverter(context);
        // Sets the width of the switch
        this.setSwitchMinWidth(displayMeasurementConverter.dpToPx((int) getResources().getDimension(R.dimen.tp_toggle_width)));
        // Setting up my colors
        int mediumGreen = ContextCompat.getColor(context, R.color.medium_green);
        int mediumGrey = ContextCompat.getColor(context, R.color.medium_grey);
        int alphaMediumGreen = Color.argb(127, Color.red(mediumGreen), Color.green(mediumGreen), Color.blue(mediumGreen));
        int alphaMediumGrey = Color.argb(127, Color.red(mediumGrey), Color.green(mediumGrey), Color.blue(mediumGrey));
        // Sets the tints for the thumb in different states
        DrawableCompat.setTintList(this.getThumbDrawable(), new ColorStateList(
                new int[][]{
                        new int[]{android.R.attr.state_checked},
                        new int[]{}
                },
                new int[]{
                        mediumGreen,
                        ContextCompat.getColor(getContext(), R.color.light_grey)
                }));
        // Sets the tints for the track in different states
        DrawableCompat.setTintList(this.getTrackDrawable(), new ColorStateList(
                new int[][]{
                        new int[]{android.R.attr.state_checked},
                        new int[]{}
                },
                new int[]{
                        alphaMediumGreen,
                        alphaMediumGrey
                }));
    }
}

Whenever I want to use the CustomizedSwitch, I just add one to my xml file.

For ignoring all warnings use this sample, on the top of your code :

error_reporting(0);

It doesn't matter which of those extensions you'd use. Pick whichever you like more, just be consistent with naming. The only exception I'm aware of with this naming convention is that I couldn't make WinDDK (or is it WDK now?) to compile .cc files. On Linux though that's hardly a problem.

The problem is that you are using getSystemResourceAsStream. Use simply getResourceAsStream. System resources load from the system classloader, which is almost certainly not the class loader that your jar is loaded into when run as a webapp.

It works in Eclipse because when launching an application, the system classloader is configured with your jar as part of its classpath. (E.g. java -jar my.jar will load my.jar in the system class loader.) This is not the case with web applications - application servers use complex class loading to isolate webapplications from each other and from the internals of the application server. For example, see the tomcat classloader how-to, and the diagram of the classloader hierarchy used.

EDIT: Normally, you would call getClass().getResourceAsStream() to retrieve a resource in the classpath, but as you are fetching the resource in a static initializer, you will need to explicitly name a class that is in the classloader you want to load from. The simplest approach is to use the class containing the static initializer, e.g.

[public] class MyClass {
  static
  {
    ...
    props.load(MyClass.class.getResourceAsStream("/someProps.properties"));
  }
}

As the answers here demonstrates nicely, yes, there are several ways. However, in PHP you rarely actually need to do that. The "dogmatic way" to write PHP is to rely on the language's loose typing system, which will transparently coerce the type as needed. For integer values, this is usually without trouble. You should be very careful with floating point values, though.

The WordPress password hasher implements the Portable PHP password hashing framework, which is used in Content Management Systems like WordPress and Drupal.

They used to use MD5 in the older versions, but sadly for me, no more. You can generate hashes using this encryption scheme at http://scriptserver.mainframe8.com/wordpress_password_hasher.php.

Use this code to not only check if the memcache extension is enabled, but also whether the daemon is running and able to store and retrieve data successfully:

<?php
if (class_exists('Memcache')) {
    $server = 'localhost';
    if (!empty($_REQUEST['server'])) {
        $server = $_REQUEST['server'];
    }
    $memcache = new Memcache;
    $isMemcacheAvailable = @$memcache->connect($server);

    if ($isMemcacheAvailable) {
        $aData = $memcache->get('data');
        echo '<pre>';
        if ($aData) {
            echo '<h2>Data from Cache:</h2>';
            print_r($aData);
        } else {
            $aData = array(
                'me' => 'you',
                'us' => 'them',
            );
            echo '<h2>Fresh Data:</h2>';
            print_r($aData);
            $memcache->set('data', $aData, 0, 300);
        }
        $aData = $memcache->get('data');
        if ($aData) {
            echo '<h3>Memcache seem to be working fine!</h3>';
        } else {
            echo '<h3>Memcache DOES NOT seem to be working!</h3>';
        }
        echo '</pre>';
    }
}
if (!$isMemcacheAvailable) {
    echo 'Memcache not available';
}

I couldn't get the parse ifconfig script to work for me on an AMI so got this to work measuring received traffic averaged over 10 seconds

date && rxstart=`ifconfig eth0 | grep bytes | awk '{print $2}' | cut -d : -f 2` && sleep 10 && rxend=`ifconfig eth0 | grep bytes | awk '{print $2}' | cut -d : -f 2` && difference=`expr $rxend - $rxstart` && echo "Received `expr $difference / 10` bytes per sec"

Sorry, it's ever so cheap and nasty but it worked!

Starting from Java 10:

Set<E> oldSet = Set.of();
Set<E> newSet = Set.copyOf(oldSet);

Set.copyOf() returns an unmodifiable Set containing the elements of the given Collection.

The given Collection must not be null, and it must not contain any null elements.

I wanted a more compact output than the great answers above using lapply, so here's an alternative wrapped as a small function.

# Example data
df <-
    data.frame(
        w = seq.int(10),
        x = LETTERS[seq.int(10)],
        y = factor(letters[seq.int(10)]),
        z = seq(
            as.POSIXct('2020-01-01'),
            as.POSIXct('2020-10-01'),
            length.out = 10
        )
    )

# Function returning compact column classes
col_classes <- function(df) {
    t(as.data.frame(lapply(df, function(x) paste(class(x), collapse = ','))))
}

# Return example data's column classes
col_classes(df)

  [,1]            
w "integer"       
x "character"     
y "factor"        
z "POSIXct,POSIXt"

I use a variant of the above, and isolate sections of my app to be embedded in differing NavControllers. This way, i don't have to reset visibility. Very useful in startup sequences, for example.

var inValid = new RegExp('^[_A-z0-9]{1,}$');
var value = "test string";
var k = inValid.test(value);
alert(k);

This will work:

#div{
     max-height:300px;
     overflow:hidden;
}
#div:hover{
     overflow-y:scroll;
}

you want something like:

SELECT count(id), SUM(hour) as totHour, SUM(kind=1) as countKindOne;

Note that your second example was close, but the IF() function always takes three arguments, so it would have had to be COUNT(IF(kind=1,1,NULL)). I prefer the SUM() syntax shown above because it's concise.

In getUserById you shouldn't create a new object (user1) which isn't used. Just assign it to the already (but null) initialized user. Otherwise Hibernate.initialize(user); is actually Hibernate.initialize(null);

Here's the new getUserById (I haven't tested this ;)):

public User getUserById(Long user_id) {
    Session session = null;
    Object user = null;
    try {
        session = HibernateUtil.getSessionFactory().openSession();
        user = (User)session.load(User.class, user_id);
        Hibernate.initialize(user);
    } catch (Exception e) {
       e.printStackTrace();
    } finally {
        if (session != null && session.isOpen()) {
            session.close();
        }
    }
    return user;
}

You can do it like this:

public void LogEmployees<T>(List<T> list) // Or IEnumerable<T> list
{
    foreach (T item in list)
    {

    }
}

... but you won't get to do much with each item. You could call ToString, but you won't be able to use (say) Name and Id directly.

If you want programmatic setText without add string to string.xml

see its hexadecimal code here:

http://fortawesome.github.io/Font-Awesome/cheatsheet/

replace  to 0xf066

 Typeface typeface = Typeface.createFromAsset(getAssets(), "fontawesome-webfont.ttf");
    textView.setTypeface(typeface);
    textView.setText(new String(new char[]{0xf006 }));

Open Registry Editor by pressing Win + R and type regedit Enter

Navigate to:

\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Client

Change the value of DisabledByDefault key 0 to 1

Then restart the Visual Studio.

There can be a problem with "\00a0" in pseudo-elements because it takes the text-decoration of its defining element, so that, for example, if the defining element is underlined, then the white space of the pseudo-element is also underlined.

The easiest way to deal with this is to define the opacity of the pseudo-element to be zero, eg:

element:before{
  content: "_";
  opacity: 0;
}
