HTTPS has encryption/decryption overhead so it will always be slightly slower. SSL termination is very CPU intensive. If you have devices to offload SSL, the difference in latencies might be barely noticeable depending on the load your servers are under.

To install OpenJDK 8 JRE using yum with non root user, run this command:

sudo yum install java-1.8.0-openjdk

to verify java -version

UPDATE:

After all the details summarized and discussed, I spent 2 fair hours in checking the options, and this update is to dot all is.

Preparations

First of all, I performed a clean Office 2010 x86 install on Clean Win7 SP1 Ultimate x64 virtual machine powered by VMWare (this is usual routine for my everyday testing tasks, so I have many of them deployed).

Then, I changed only the following Excel options (i.e. all the other are left as is after installation):

• Advanced > General > Ask to update automatic links checked:

• Trust Center > Trust Center Settings... > External Content > Enable All... (although that one that relates to Data Connections is most likely not important for the case):

Preconditions

I prepared and placed to C:\ a workbook exactly as per @Siddharth Rout suggestions in his updated answer (shared for your convenience): https://www.dropbox.com/s/mv88vyc27eljqaq/Book1withLinkToBook2.xlsx Linked book was then deleted so that link in the shared book is unavailable (for sure).

Manual Opening

The above shared file shows on opening (having the above listed Excel options) 2 warnings - in the order of appearance:

WARNING #1

After click on Update I expectedly got another:

WARNING #2

So, I suppose my testing environment is now pretty much similar to OP's) So far so good, we finally go to

VBA Opening

Now I'll try all possible options step by step to make the picture clear. I'll share only relevant lines of code for simplicity (complete sample file with code will be shared in the end).

1. Simple Application.Workbooks.Open

Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx"

No surprise - this produces BOTH warnings, as for manual opening above.

2. Application.DisplayAlerts = False

Application.DisplayAlerts = False
Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx"
Application.DisplayAlerts = True

This code ends up with WARNING #1, and either option clicked (Update / Don't Update) produces NO further warnings, i.e. Application.DisplayAlerts = False suppresses WARNING #2.

3. Application.AskToUpdateLinks = False

Application.AskToUpdateLinks = False
Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx"
Application.AskToUpdateLinks = True

Opposite to DisplayAlerts, this code ends up with WARNING #2 only, i.e. Application.AskToUpdateLinks = False suppresses WARNING #1.

4. Double False

Application.AskToUpdateLinks = False
Application.DisplayAlerts = False
Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx"
Application.DisplayAlerts = True
Application.AskToUpdateLinks = True

Apparently, this code ends up with suppressing BOTH WARNINGS.

5. UpdateLinks:=False

Application.Workbooks.Open Filename:="C:\Book1withLinkToBook2.xlsx", UpdateLinks:=False

Finally, this 1-line solution (originally proposed by @brettdj) works the same way as Double False: NO WARNINGS are shown!

Conclusions

Except a good testing practice and very important solved case (I may face such issues everyday while sending my workbooks to 3rd party, and now I'm prepared), 2 more things learned:

1. Excel options DO matter, regardless of version - especially when we come to VBA solutions.
2. Every trouble has short and elegant solution - together with not obvious and complicated one. Just one more proof for that!)

Thanks very much to everyone who contributed to the solution, and especially OP who raised the question. Hope my investigations and thoroughly described testing steps were helpful not only for me)

Sample file with the above code samples is shared (many lines are commented deliberately): https://www.dropbox.com/s/9bwu6pn8fcogby7/NoWarningsOpen.xlsm

Original answer (tested for Excel 2007 with certain options):

This code works fine for me - it loops through ALL Excel files specified using wildcards in the InputFolder:

Sub WorkbookOpening2007()

Dim InputFolder As String
Dim LoopFileNameExt As String

InputFolder = "D:\DOCUMENTS\" 'Trailing "\" is required!

LoopFileNameExt = Dir(InputFolder & "*.xls?")
Do While LoopFileNameExt <> ""

Application.DisplayAlerts = False
Application.Workbooks.Open (InputFolder & LoopFileNameExt)
Application.DisplayAlerts = True

LoopFileNameExt = Dir
Loop

End Sub

I tried it with books with unavailable external links - no warnings.

Sample file: https://www.dropbox.com/s/9bwu6pn8fcogby7/NoWarningsOpen.xlsm

I agree with @adietisheim and the rest of people that suggest HttpClient.

I spent time trying to make a simple call to rest service with HttpURLConnection and it hadn't convinced me and after that I tried with HttpClient and it was really more easy, understandable and nice.

An example of code to make a put http call is as follows:

DefaultHttpClient httpClient = new DefaultHttpClient();

HttpPut putRequest = new HttpPut(URI);

StringEntity input = new StringEntity(XML);
input.setContentType(CONTENT_TYPE);

putRequest.setEntity(input);
HttpResponse response = httpClient.execute(putRequest);

Template File

<h1>{title}</h1>
<div>{username}</div>

PHP

if (($text = file_get_contents("file.html")) === false) {
    $text = "";
}

$text = str_replace("{title}", "Title Here", $text);
$text = str_replace("{username}", "Username Here", $text);

then you can echo $text as string

Log in as root, then run the following MySQL commands:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost';
FLUSH PRIVILEGES;

i suggest you put it on route filter before on {project}/application/routes.php

Route::filter('before', function()
{
    // Do stuff before every request to your application...    
    Asset::add('jquery', 'js/jquery-2.0.0.min.js');
    Asset::add('style', 'template/style.css');
    Asset::add('style2', 'css/style.css');

});

and using blade template engine

{{ Asset::styles() }}
{{ Asset::scripts(); }}

As you point 499 a connection abortion logged by the nginx. But usually this is produced when your backend server is being too slow, and another proxy timeouts first or the user software aborts the connection. So check if uWSGI is answering fast or not of if there is any load on uWSGI / Database server.

In many cases there are some other proxies between the user and nginx. Some can be in your infrastructure like maybe a CDN, Load Balacer, a Varnish cache etc. Others can be in user side like a caching proxy etc.

If there are proxies on your side like a LoadBalancer / CDN ... you should set the timeouts to timeout first your backend and progressively the other proxies to the user.

If you have:

user >>> CDN >>> Load Balancer >>> Nginx >>> uWSGI

I'll recommend you to set:

• n seconds to uWSGI timeout
• n+1 seconds to nginx timeout
• n+2 senconds to timeout to Load Balancer
• n+3 seconds of timeout to the CDN.

If you can't set some of the timeouts (like CDN) find whats is its timeout and adjust the others according to it (n, n-1...).

This provides a correct chain of timeouts. and you'll find really whose giving the timeout and return the right response code to the user.

The answers did help, but I think a full implementation of this will help a lot of people.

You might find useful mosaic plot from statsmodels. Which can also give statistical highlighting for the variances.

from statsmodels.graphics.mosaicplot import mosaic
plt.rcParams['font.size'] = 16.0
mosaic(df, ['direction', 'colour']);

But beware of the 0 sized cell - they will cause problems with labels.

If you want to increase the height of the input field, you can specify line-height css property for the input field.

input {
    line-height: 2em; // 2em is (2 * default line height)
}

I have a better solution after read all of the existed answers. Everything could done by a workflow in a single right click. NO additional software, NO complicated command line stuffs and NO shell tricks.

The automator workflow:

• Input: files or folders from any application.
• Step 1: Create Archive, the system builtin with default parameters.

• Step 2: Run Shell command, with input as parameters. Copy command below.

  zip -d "$@" "__MACOSX/*" || true

  zip -d "$@" "*/.DS_Store" || true

Save it and we are done! Just right click folder or bulk of files and choose workflow from services menu. Archive with no metadata will be created alongside.

This solution seems to be working well for me. It builds on @pavok's solution by preserving ctrl key commands.

document.querySelector("input").addEventListener("keypress", function (e) {
  if (
    e.key.length === 1 && e.key !== '.' && isNaN(e.key) && !e.ctrlKey || 
    e.key === '.' && e.target.value.toString().indexOf('.') > -1
  ) {
    e.preventDefault();
  }
});

Run your container with --privileged flag.

docker run -it --privileged ...

Things changed a lot since the answer was posted. Now you will see a small key symbol on the right hand side of the URL bar.
Click the symbol and it will take you directly to the saved password dialog where you can remove the password.

How about just using the built-in types like this:

config = {
    "mysql": {
        "user": "root",
        "pass": "secret",
        "tables": {
            "users": "tb_users"
        }
        # etc
    }
}

You'd access the values as follows:

config["mysql"]["tables"]["users"]

If you are willing to sacrifice the potential to compute expressions inside your config tree, you could use YAML and end up with a more readable config file like this:

mysql:
  - user: root
  - pass: secret
  - tables:
    - users: tb_users

and use a library like PyYAML to conventiently parse and access the config file

Unless it's just a simplified example for the question, my advice is that drop the batch wrapper and schedule PHP directly, more specifically the php-win.exe program, which won't open unnecessary windows.

Program: c:\program files\php\php-win.exe
Arguments: D:\mydocs\mp\index.php param1 param2

Otherwise, just quote stuff as Andrew points out.

In older versions of Windows, you should be able to put everything in the single "Run" text box (as long as you quote everything that has spaces):

"c:\program files\php\php-win.exe" D:\mydocs\mp\index.php param1 param2

You need to define a Remote Java Application in the Eclipse debug configurations:

Open the debug configurations (select project, then open from menu run/debug configurations) Select Remote Java Application in the left tree and press "New" button On the right panel select your web app project and enter 8787 in the port field. Here is a link to a detailed description of this process.

When you start the remote debug configuration Eclipse will attach to the JBoss process. If successful the debug view will show the JBoss threads. There is also a disconnect icon in the toolbar/menu to stop remote debugging.

Simply restate the target field & condition;

where (field like "*AA*" and field not like "*BB*")

expand "Java Resources" and then 'Libraries' (in eclipse project). make sure that "Apache Tomcat" present.

if not follow- right click on project -> "Build Path" -> "Java Build Path" -> "Add Library" -> select "Server Runtime" -> next -> select "Apache Tomcat -> click finish

First try to understand how Entity Framework Connection string works then you will get idea of what is wrong.

1. You have two different models, Entity and ModEntity
2. This means you have two different contexts, each context has its own Storage Model, Conceptual Model and mapping between both.
3. You have simply combined strings, but how does Entity's context will know that it has to pickup entity.csdl and ModEntity will pickup modentity.csdl? Well someone could write some intelligent code but I dont think that is primary role of EF development team.
4. Also machine.config is bad idea.
5. If web apps are moved to different machine, or to shared hosting environment or for maintenance purpose it can lead to problems.
6. Everybody will be able to access it, you are making it insecure. If anyone can deploy a web app or any .NET app on server, they get full access to your connection string including your sensitive password information.

Another alternative is, you can create your own constructor for your context and pass your own connection string and you can write some if condition etc to load defaults from web.config

Better thing would be to do is, leave connection strings as it is, give your application pool an identity that will have access to your database server and do not include username and password inside connection string.

yes you can use MapView in v2... for further details you can get help from this

I found I had problems with this approach, basically because I was trying to write the output to a file and it was non encoded properly. Since JS seems to use UCS-2 encoding (source, source), we need to stretch this solution a step further, here's my enhanced solution that works to me.

I had no difficulties with generic text, but when it was down to Arab or Korean, the output file didn't have all the chars but instead was showing error characters

File output: ","10k unit":"",Follow:"Õ©íüY‹","Follow %{screen_name}":"%{screen_name}U“’Õ©íü",Tweet:"ĤüÈ","Tweet %{hashtag}":"%{hashtag} ’ĤüÈY‹","Tweet to %{name}":"%{name}U“xĤüÈY‹"},ko:{"%{followers_count} followers":"%{followers_count}…X \Ì","100K+":"100Ì tÁ","10k unit":"Ì è",Follow:"\°","Follow %{screen_name}":"%{screen_name} Ø \°X0",K:"œ",M:"1Ì",Tweet:"¸","Tweet %{hashtag}":"%{hashtag}

Original: ","10k unit":"?",Follow:"??????","Follow %{screen_name}":"%{screen_name}???????",Tweet:"????","Tweet %{hashtag}":"%{hashtag} ???????","Tweet to %{name}":"%{name}?????????"},ko:{"%{followers_count} followers":"%{followers_count}?? ???","100K+":"100? ??","10k unit":"? ??",Follow:"???","Follow %{screen_name}":"%{screen_name} ? ?????",K:"?",M:"??",Tweet:"??","Tweet %{hashtag}":"%{hashtag}

I took the information from dennis' solution and this post I found.

Here's my code:

function encode_utf8(s) {
  return unescape(encodeURIComponent(s));
}

function decode_utf8(s) {
  return decodeURIComponent(escape(s));
}

 function ab2str(buf) {
   var s = String.fromCharCode.apply(null, new Uint8Array(buf));
   return decode_utf8(decode_utf8(s))
 }

function str2ab(str) {
   var s = encode_utf8(str)
   var buf = new ArrayBuffer(s.length); 
   var bufView = new Uint8Array(buf);
   for (var i=0, strLen=s.length; i<strLen; i++) {
     bufView[i] = s.charCodeAt(i);
   }
   return bufView;
 }

This allows me to save the content to a file without encoding problems.

How it works: It basically takes the single 8-byte chunks composing a UTF-8 character and saves them as single characters (therefore an UTF-8 character built in this way, could be composed by 1-4 of these characters). UTF-8 encodes characters in a format that variates from 1 to 4 bytes in length. What we do here is encoding the sting in an URI component and then take this component and translate it in the corresponding 8 byte character. In this way we don't lose the information given by UTF8 characters that are more than 1 byte long.

You can change it by going File => Settings (Shortcut CTRL+ ALT+ S) , from Left panel Choose Appearance , Now from Right Panel choose theme.

Android Studio 2.1

Preference -> Search for Appearance -> UI options , Click on DropDown Theme

Android 2.2

Android studio -> File -> Settings -> Appearance & Behavior -> Look for UI Options

EDIT :

Import External Themes

You can download custom theme from this website. Choose your theme, download it. To set theme Go to Android studio -> File -> Import Settings -> Choose the .jar file downloaded.

Use nbio non-blocking i/o library or whatever, if you need more threads for doing I/O calls that block

Communicating between different JavaScript execution context was supported even before HTML5 if the documents was of the same origin. If not or you have no reference to the other Window object, then you could use the new postMessage API introduced with HTML5. I elaborated a bit on both approaches in this stackoverflow answer.

You can use this :

@GET("group/{id}/users")

Call<List<User>> groupList(@Path("id") int groupId, @Query("sort") String sort);

I think you can get it using subc1.text.

>>> html = """

>>> from bs4 import BeautifulSoup

>>> print soup.text


YOB: 1987
RACE: WHITE
GENDER: FEMALE
HEIGHT: 5'05''
WEIGHT: 118
EYE COLOR: GREEN
HAIR COLOR: BROWN

Or if you want to explore it, you can use .contents :

>>> p = soup.find('p')
>>> from pprint import pprint
>>> pprint(p.contents)
[u'\n',
 <strong class="offender">YOB:</strong>,
 u' 1987',

and filter out the necessary items from the list:

>>> data = dict(zip([x.text for x in p.contents[1::4]], [x.strip() for x in p.contents[2::4]]))
>>> pprint(data)

You can declare multiple type variables on a type or method. For example, using type parameters on the method:

<P, Q> int f(Set<P>, Set<Q>) {
  return 0;
}

From the fine manual:

ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;

There's no need to specify the type when you're just changing the nullability.

fill="#044B9466"

This is an RGBA color in hex notation inside the SVG, defined with hex values. This is valid, but not all programs can display it properly...

You can find the browser support for this syntax here: https://caniuse.com/#feat=css-rrggbbaa

As of August 2017: RGBA fill colors will display properly on Mozilla Firefox (54), Apple Safari (10.1) and Mac OS X Finder's "Quick View". However Google Chrome did not support this syntax until version 62 (was previously supported from version 54 with the Experimental Platform Features flag enabled).

Python doesn't have constants.

Perhaps the easiest alternative is to define a function for it:

def MY_CONSTANT():
    return 42

MY_CONSTANT() now has all the functionality of a constant (plus some annoying braces).

Read the Advanced Bash-Scripting Guide Chapter 19. Here Documents.

Here's an example which will write the contents to a file at /tmp/yourfilehere

cat << EOF > /tmp/yourfilehere
These contents will be written to the file.
        This line is indented.
EOF

Note that the final 'EOF' (The LimitString) should not have any whitespace in front of the word, because it means that the LimitString will not be recognized.

In a shell script, you may want to use indentation to make the code readable, however this can have the undesirable effect of indenting the text within your here document. In this case, use <<- (followed by a dash) to disable leading tabs (Note that to test this you will need to replace the leading whitespace with a tab character, since I cannot print actual tab characters here.)

#!/usr/bin/env bash

if true ; then
    cat <<- EOF > /tmp/yourfilehere
    The leading tab is ignored.
    EOF

If you don't want to interpret variables in the text, then use single quotes:

cat << 'EOF' > /tmp/yourfilehere
The variable $FOO will not be interpreted.
EOF

To pipe the heredoc through a command pipeline:

cat <<'EOF' |  sed 's/a/b/'
foo
bar
baz
EOF

Output:

foo
bbr
bbz

... or to write the the heredoc to a file using sudo:

cat <<'EOF' |  sed 's/a/b/' | sudo tee /etc/config_file.conf
foo
bar
baz
EOF

dt = dt.AsEnumerable().GroupBy(r => r.Field<int>("ID")).Select(g => g.First()).CopyToDataTable();

I had this problem for a couple of days now and finally figured it out! All other solutions didn't work for me btw.

Solution: I had special characters in my project path!

Just make sure to have none of those and you should be fine or at least one of the other solutions should work for you.

Hope this helps someone!

You could also use a LEFT JOIN and IS NULL condition:

SELECT 
  mac, 
  creation_date 
FROM 
  logs
    LEFT JOIN consols ON logs.mac = consols.mac
WHERE 
  logs_type_id=11
AND
  consols.mac IS NULL;

An index on the "mac" columns might improve performance.

i use like tim say sprintf('%0.6f', x), it's a string then i change it to number by using command str2double(x).

This one works with Firefox 43.0 (older not tested):

dl.js:

function download() {
  var msg="Hello world!";
  var blob = new File([msg], "hello.bin", {"type": "application/octet-stream"});

  var a = document.createElement("a");
  a.href = URL.createObjectURL(blob);

  window.location.href=a;
}

dl.html

<html lang="en" xmlns="http://www.w3.org/1999/xhtml">

<head>
    <meta charset="utf-8"/>
    <title>Test</title>
    <script type="text/javascript" src="dl.js"></script>
</head>

<body>
<button id="create" type="button" onclick="download();">Download</button>
</body>
</html>

If button is clicked it offered a file named hello.bin for download. Trick is to use File instead of Blob.

Sometimes two classes may have some parameter names in common. In that case, you can't pop the key-value pairs off of **kwargs or remove them from *args. Instead, you can define a Base class which unlike object, absorbs/ignores arguments:

class Base(object):
    def __init__(self, *args, **kwargs): pass

class A(Base):
    def __init__(self, *args, **kwargs):
        print "A"
        super(A, self).__init__(*args, **kwargs)

class B(Base):
    def __init__(self, *args, **kwargs):
        print "B"
        super(B, self).__init__(*args, **kwargs)

class C(A):
    def __init__(self, arg, *args, **kwargs):
        print "C","arg=",arg
        super(C, self).__init__(arg, *args, **kwargs)

class D(B):
    def __init__(self, arg, *args, **kwargs):
        print "D", "arg=",arg
        super(D, self).__init__(arg, *args, **kwargs)

class E(C,D):
    def __init__(self, arg, *args, **kwargs):
        print "E", "arg=",arg
        super(E, self).__init__(arg, *args, **kwargs)

print "MRO:", [x.__name__ for x in E.__mro__]
E(10)

yields

MRO: ['E', 'C', 'A', 'D', 'B', 'Base', 'object']
E arg= 10
C arg= 10
A
D arg= 10
B

Note that for this to work, Base must be the penultimate class in the MRO.

ucfagls is right, providing you use the plot() command. If not, please give us more detail.

In any case, you can control every axis seperately by using the axis() command and the xaxt/yaxt options in plot(). Using the data of ucfagls, this becomes :

plot(Y ~ X, data=foo,yaxt="n")
axis(2,cex.axis=2)

the option yaxt="n" is necessary to avoid that the plot command plots the y-axis without changing. For the x-axis, this works exactly the same :

plot(Y ~ X, data=foo,xaxt="n")
axis(1,cex.axis=2)

See also the help files ?par and ?axis

Edit : as it is for a barplot, look at the options cex.axis and cex.names :

tN <- table(sample(letters[1:5],100,replace=T,p=c(0.2,0.1,0.3,0.2,0.2)))

op <- par(mfrow=c(1,2))
barplot(tN, col=rainbow(5),cex.axis=0.5) # for the Y-axis
barplot(tN, col=rainbow(5),cex.names=0.5) # for the X-axis
par(op)

Your first code will work by doing this

DateTime myDateTime = DateTime.Now;
string sqlFormattedDate = myDateTime.ToString("yyyy-MM-dd HH:mm:ss"); //Remove myDateTime.Date part 

Even simpler one that I just wrote:

public class JsonFormatter
{
    public static string Indent = "    ";

    public static string PrettyPrint(string input)
    {
        var output = new StringBuilder(input.Length * 2);
        char? quote = null;
        int depth = 0;

        for(int i=0; i<input.Length; ++i)
        {
            char ch = input[i];

            switch (ch)
            {
                case '{':
                case '[':
                    output.Append(ch);
                    if (!quote.HasValue)
                    {
                        output.AppendLine();
                        output.Append(Indent.Repeat(++depth));
                    }
                    break;
                case '}':
                case ']':
                    if (quote.HasValue)  
                        output.Append(ch);
                    else
                    {
                        output.AppendLine();
                        output.Append(Indent.Repeat(--depth));
                        output.Append(ch);
                    }
                    break;
                case '"':
                case '\'':
                    output.Append(ch);
                    if (quote.HasValue)
                    {
                        if (!output.IsEscaped(i))
                            quote = null;
                    }
                    else quote = ch;
                    break;
                case ',':
                    output.Append(ch);
                    if (!quote.HasValue)
                    {
                        output.AppendLine();
                        output.Append(Indent.Repeat(depth));
                    }
                    break;
                case ':':
                    if (quote.HasValue) output.Append(ch);
                    else output.Append(" : ");
                    break;
                default:
                    if (quote.HasValue || !char.IsWhiteSpace(ch)) 
                        output.Append(ch);
                    break;
            }
        }

        return output.ToString();
    }
}

Necessary extensions:

    public static string Repeat(this string str, int count)
    {
        return new StringBuilder().Insert(0, str, count).ToString();
    }

    public static bool IsEscaped(this string str, int index)
    {
        bool escaped = false;
        while (index > 0 && str[--index] == '\\') escaped = !escaped;
        return escaped;
    }

    public static bool IsEscaped(this StringBuilder str, int index)
    {
        return str.ToString().IsEscaped(index);
    }

I know one aspect: Although CBC gives better security by changing the IV for each block, it's not applicable to randomly accessed encrypted content (like an encrypted hard disk).

So, use CBC (and the other sequential modes) for sequential streams and ECB for random access.

You can simply use the following syntax to create a new class (this is handy if you're creating a factory):

$className = $whatever;
$object = new $className;

As an (exceptionally crude) example factory method:

public function &factory($className) {

    require_once($className . '.php');
    if(class_exists($className)) return new $className;

    die('Cannot create new "' . $className . '" class - includes not found or class unavailable.');
}

A browser's default styles are defined in its user agent stylesheet, the sources of which you can find here. Unfortunately, the Cascading and Inheritance level 3 spec does not appear to propose a way to reset a style property to its browser default. However there are plans to reintroduce a keyword for this in Cascading and Inheritance level 4 — the working group simply hasn't settled on a name for this keyword yet (the link currently says revert, but it is not final). Information about browser support for revert can be found on caniuse.com.

While the level 3 spec does introduce an initial keyword, setting a property to its initial value resets it to its default value as defined by CSS, not as defined by the browser. The initial value of display is inline; this is specified here. The initial keyword refers to that value, not the browser default. The spec itself makes this note under the all property:

For example, if an author specifies all: initial on an element it will block all inheritance and reset all properties, as if no rules appeared in the author, user, or user-agent levels of the cascade.

This can be useful for the root element of a "widget" included in a page, which does not wish to inherit the styles of the outer page. Note, however, that any "default" style applied to that element (such as, e.g. display: block from the UA style sheet on block elements such as <div>) will also be blown away.

So I guess the only way right now using pure CSS is to look up the browser default value and set it manually to that:

div.foo { display: inline-block; }
div.foo.bar { display: block; }

(An alternative to the above would be div.foo:not(.bar) { display: inline-block; }, but that involves modifying the original selector rather than an override.)

Try marking the field with [NonSerialized()] attribute. This will tell the serializer to ignore the field.

It's not really something you need jQuery to do. There is a very simple plain old javascript method for doing this:

window.open('http://www.google.com','GoogleWindow', 'width=800, height=600');

That's it.

The first arg is the url, the second is the name of the window, this should be specified because IE will throw a fit about trying to use window.opener later if there was no window name specified (just a little FYI), and the last two params are width/height.

EDIT: Full specification can be found in the link mmmshuddup provided.

You could also use zip

I downloaded the desired certificate again and installed it. Now I don't see an empty file in Xcode. The build also works now (no code sign error).

What I also did: I downloaded the WWDR and installed it, but I don't know if that was the reason (because I think it's always the same)

Probably because I didn't shut down my dev server properly or a similar reason. To fix it, remove the lock and start the server with: sudo rm /var/lib/mongodb/mongod.lock ; sudo start mongodb

Usage of formdata in react-native

I have used react-native-image-picker to select photo. In my case after choosing the photp from mobile. I'm storing it's info in component state. After, I'm sending POST request using fetch like below

const profile_pic = {
  name: this.state.formData.profile_pic.fileName,
  type: this.state.formData.profile_pic.type,
  path: this.state.formData.profile_pic.path,
  uri: this.state.formData.profile_pic.uri,
}
const formData = new FormData()
formData.append('first_name', this.state.formData.first_name);
formData.append('last_name', this.state.formData.last_name);
formData.append('profile_pic', profile_pic);
const Token = 'secret'

fetch('http://10.0.2.2:8000/api/profile/', {
    method: "POST",
    headers: {
      Accept: "application/json",
      "Content-Type": "multipart/form-data",
      Authorization: `Token ${Token}`
    },
    body: formData
  })
  .then(response => console.log(response.json()))

If you use IIS, I'd suggest trying IIS CORS module.
It's easy to configure and works for all types of controllers.

Here is an example of configuration:

    <system.webServer>
        <cors enabled="true" failUnlistedOrigins="true">
            <add origin="*" />
            <add origin="https://*.microsoft.com"
                 allowCredentials="true"
                 maxAge="120"> 
                <allowHeaders allowAllRequestedHeaders="true">
                    <add header="header1" />
                    <add header="header2" />
                </allowHeaders>
                <allowMethods>
                     <add method="DELETE" />
                </allowMethods>
                <exposeHeaders>
                    <add header="header1" />
                    <add header="header2" />
                </exposeHeaders>
            </add>
            <add origin="http://*" allowed="false" />
        </cors>
    </system.webServer>

The closest equivalent to your VB would be (see this):

Convert.IsDBNull()

But there are a number of ways to do this, and most are linked from here

Why could you not just make a file structure on the Windows file system and populate it with your desired names, then use a screen grabber like HyperSnap (or the ubiquitous Alt-PrtScr) to capture a section of the Explorer window.

I did this when 'demoing' an internet application which would have collapsible sections, I just had to create files that looked like my desired entries.

HyperSnap gives JPGs at least (probably others but I've never bothered to investigate).

Or you could screen capture the icons +/- from Explorer and use them within MS Word Draw itself to do your picture, but I've never been able to get MS Word Draw to behave itself properly.

There's actually an easier way than exporting and unsetting or sourcing again (at least in bash, as long as you're ok with passing the environment variables manually):

let a.sh be

#!/bin/bash
secret="winkle my tinkle"
echo Yo, lemme tell you \"$secret\", b.sh!
Message=$secret ./b.sh

and b.sh be

#!/bin/bash
echo I heard \"$Message\", yo

Observed output is

[rob@Archie test]$ ./a.sh
Yo, lemme tell you "winkle my tinkle", b.sh!
I heard "winkle my tinkle", yo

The magic lies in the last line of a.sh, where Message, for only the duration of the invocation of ./b.sh, is set to the value of secret from a.sh. Basically, it's a little like named parameters/arguments. More than that, though, it even works for variables like $DISPLAY, which controls which X Server an application starts in.

Remember, the length of the list of environment variables is not infinite. On my system with a relatively vanilla kernel, xargs --show-limits tells me the maximum size of the arguments buffer is 2094486 bytes. Theoretically, you're using shell scripts wrong if your data is any larger than that (pipes, anyone?)

The before and after pseudo-selectors don't insert HTML elements — they insert text before or after the existing content of the targeted element. Because image elements don't contain text or have descendants, neither img:before or img:after will do you any good. This is also the case for elements like <br> and <hr> for the same reason.

I used this one for list view loading may helpful.

ListView listView;
LinearLayout layout;
List<String> stringValues;
ArrayAdapter<String> adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    listView = (ListView) findViewById(R.id.listView);
    layout = (LinearLayout) findViewById(R.id.progressbar_view);

    stringValues = new ArrayList<String>();

    adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, stringValues);

    listView.setAdapter(adapter);
    new Task().execute();
}

class Task extends AsyncTask<String, Integer, Boolean> {
    @Override
    protected void onPreExecute() {
        layout.setVisibility(View.VISIBLE);
        listView.setVisibility(View.GONE);
        super.onPreExecute();
    }

    @Override
    protected void onPostExecute(Boolean result) {
        layout.setVisibility(View.GONE);
        listView.setVisibility(View.VISIBLE);
        adapter.notifyDataSetChanged();
        super.onPostExecute(result);
    }

    @Override
    protected Boolean doInBackground(String... params) {
        stringValues.add("String 1");
        stringValues.add("String 2");
        stringValues.add("String 3");
        stringValues.add("String 4");
        stringValues.add("String 5");

        try {
            Thread.sleep(3000);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
}
}

this activity display progress for 3sec then it will display listview, instead of adding data statically to stringValues list you can get data from server in doInBackground() and display it.

For GNU/Linux & MacOS (or generally UNIX like) systems, I've used below method which works fine:

private int tryGetPid(Process process)
{
    if (process.getClass().getName().equals("java.lang.UNIXProcess"))
    {
        try
        {
            Field f = process.getClass().getDeclaredField("pid");
            f.setAccessible(true);
            return f.getInt(process);
        }
        catch (IllegalAccessException | IllegalArgumentException | NoSuchFieldException | SecurityException e)
        {
        }
    }

    return 0;
}

Follow up to accepted answer.

You need something other than CTRL-D to designate the end if using this in a script. Try this instead:

cat << EOF >> filename
This is text entered via the keyboard or via a script.
EOF

This will append text to the stated file (not including "EOF").

It utilizes a here document (or heredoc).

However if you need sudo to append to the stated file, you will run into trouble utilizing a heredoc due to I/O redirection if you're typing directly on the command line.

This variation will work when you are typing directly on the command line:

sudo sh -c 'cat << EOF >> filename
This is text entered via the keyboard.
EOF'

Or you can use tee instead to avoid the command line sudo issue seen when using the heredoc with cat:

tee -a filename << EOF
This is text entered via the keyboard or via a script.
EOF

According to Effective Java 2nd edition (Item 13):

"If a package-private top-level class (or interface) is used by only one class, consider making the top-level class a private nested class of the sole class that uses it (Item 22). This reduces its accessibility from all the classes in its package to the one class that uses it. But it is far more important to reduce the accessibility of a gratuitously public class than a package-private top-level class: ... "

The nested class may be static or non-static based on whether the member class needs access to the enclosing instance (Item 22).

The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. "r-" for a red line, or by explicitely stating the color argument.

import matplotlib.pyplot as plt

plt.plot([1,2,3], [2,3,1], "r-") # red line
plt.plot([1,2,3], [5,5,3], color="blue") # blue line

plt.show()

See also the plot command's documentation.

In case you already have a line with a certain color, you can change that with the lines2D.set_color() method.

line, = plt.plot([1,2,3], [4,5,3], color="blue")
line.set_color("black")

import matplotlib.pyplot as plt
import pandas as pd

df = pd.DataFrame({ "x" : [1,2,3,5], "y" : [3,5,2,6]})
df.plot("x", "y", color="r") #plot red line

plt.show()

If you want to change this color later on, you can do so by

plt.gca().get_lines()[0].set_color("black")

This will get you the first (possibly the only) line of the current active axes.
In case you have more axes in the plot, you could loop through them

for ax in plt.gcf().axes:
    ax.get_lines()[0].set_color("black")

and if you have more lines you can loop over them as well.

I was able to setup Oracle Instant Client (Basic) 11g2 and Oracle ODBC (32bit) drivers on my 32bit Windows 7 PC. Note: you'll need a 'tnsnames.ora' file because it doesn't come with one. You can Google examples and copy/paste into a text file, change the parameters for your environment.

Setting up Oracle Instant Client-Basic 11g2 (Win7 32-bit)
(I think there's another step or two if your using 64-bit)

Oracle Instant Client

• Unzip Oracle Instant Client - Basic
• Put contents in folder like "C:\instantclient"
• Edit PATH evironment variable, add path to Instant Client folder to the Variable Value.
• Add new Variable called "TNS_ADMIN" point to same folder as Instant Client.
• I had to create a "tnsnames.ora" file because it doesn't come with one. Put it in same folder as the client.
• reboot or use Task Manager to kill "explorer.exe" and restart it to refresh the PATH environment variables.

ODBC Drivers

• Unzip ODBC drivers
• Copy all files into same folder as client "C:\instantclient"
• Use command prompt to run "odbc_install.exe" (should say it was successful)

Note: The "un-documented" things that were hanging me up where...
- All files (Client and Drivers) needed to be in the same folder (nothing in sub-folders).
- Running the ODBC driver from the command prompt will allow you to see if it installs successfully. Double-clicking the installer just flashed a box on the screen, no idea it was failing because no error dialog.

After you've done this you should be able to setup a new DSN Data Source using the Oracle ODBC driver.
-Hope this helps someone else.

Try this one.

cmbEmployeeStatus.SelectedIndex = cmbEmployeeStatus.FindString(employee.employmentstatus);

Hope that helps. :)

As you noticed, these are Makefile {macros or variables}, not compiler options. They implement a set of conventions. (Macros is an old name for them, still used by some. GNU make doc calls them variables.)

The only reason that the names matter is the default make rules, visible via make -p, which use some of them.

If you write all your own rules, you get to pick all your own macro names.

In a vanilla gnu make, there's no such thing as CCFLAGS. There are CFLAGS, CPPFLAGS, and CXXFLAGS. CFLAGS for the C compiler, CXXFLAGS for C++, and CPPFLAGS for both.

Why is CPPFLAGS in both? Conventionally, it's the home of preprocessor flags (-D, -U) and both c and c++ use them. Now, the assumption that everyone wants the same define environment for c and c++ is perhaps questionable, but traditional.

P.S. As noted by James Moore, some projects use CPPFLAGS for flags to the C++ compiler, not flags to the C preprocessor. The Android NDK, for one huge example.

You only have to add these two lines in your pom.xml. After that, your problem will be gone.

<!--pom.xml-->
<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

If you know about how many you want on a page, you could always do this. It will start a new page after every 20th item.

.row-item:nth-child(20n) {
    page-break-after: always;
    page-break-inside: avoid;
}

I know this is not the problem you had, however another reason this could happen is you have a non background thread open in your application.

using System;
using System.Threading;
using System.Windows.Forms;

namespace Sandbox_Form
{
    static class Program
    {
        private static Thread thread;

        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);

            thread = new Thread(BusyWorkThread);
            thread.IsBackground = false;
            thread.Start();

            Application.Run(new Form());

        }

        public static void BusyWorkThread()
        {
            while (true)
            {
                Thread.Sleep(1000);
            }
        }
    }
}

When IsBackground is false it will keep your program open till the thread completes, if you set IsBackground to true the thread will not keep the program open. Things like BackgroundWoker, ThreadPool, and Task all internally use a thread with IsBackground set to true.

There are many way, you check angular version Just pent the comand prompt(for windows) and type

1. ng version
2. ng v
3. ng -v

4. You can pakage.json file

5.You can check in browser by presing F12 then goto elements tab

Full understanding of subversion about(x.x.x) please see angular documentation angularJS and angular 2+

You have to specify project_id:

reverse('edit_project', kwargs={'project_id':4})

You can just use Arrays#sort(), it's working perfectly. See this example :

String [] a = {"English","German","Italian","Korean","Blablablabla.."};
//before sort
for(int i = 0;i<a.length;i++)
{
  System.out.println(a[i]);
}
Arrays.sort(a);
System.out.println("After sort :");
for(int i = 0;i<a.length;i++)
{
  System.out.println(a[i]);
}

You can fix the issue by deleting the __MigrationHistory table which is created automatically in the database and logs any update in the database using code-first migrations. Here, in this case, you manually changed your database while EF assumed you had to do it with the migration tool. Deleting the table means to the EF that there are no updates and no need to do code-first migrations thus it works perfectly fine.

You have done it correctly. The pull request will automatically update. The process is:

1. Open pull request
2. Commit changes based on feedback in your local repo
3. Push to the relevant branch of your fork

The pull request will automatically add the new commits at the bottom of the pull request discussion (ie, it's already there, scroll down!)

import * as express from "express";

This is the suggested way of doing it because it is the standard for JavaScript (ES6/2015) since last year.

In any case, in your tsconfig.json file, you should target the module option to commonjs which is the format supported by nodejs.

write display:inline-block instead of float:left.

li {
        display:inline-block;
        *display:inline; /*IE7*/
        *zoom:1; /*IE7*/
        background:blue;
        color:white;
        margin-right:10px;
}

JSONObject json = new JSONObject();
json.put("fromZIPCode","123456"); 

JSONObject json1 = new JSONObject();
json1.put("fromZIPCode","123456"); 
       sList.add(json1);
       sList.add(json);

System.out.println(sList);

Output will be

[{"fromZIPCode":"123456"},{"fromZIPCode":"123456"}]

Create a new constraint first and then drop the old one.
That way you ensure that:

• constraints are always in place
• existing rows do not violate new constraints
• no illegal INSERT/UPDATEs are attempted after you drop a constraint and before a new one is applied.

Works for me. Notice the use of background-image for transition.

#poster-img {
  background-repeat: no-repeat;
  background-position: center;
  position: absolute;
  overflow: hidden;
  -webkit-transition: background-image 1s ease-in-out;
  transition: background-image 1s ease-in-out;
}

Related issue:

I was having trouble converting struct to JSON, sending it as response from Golang, then, later catch the same in JavaScript via Ajax.

Wasted a lot of time, so posting solution here.

In Go:

// web server

type Foo struct {
    Number int    `json:"number"`
    Title  string `json:"title"`
}

foo_marshalled, err := json.Marshal(Foo{Number: 1, Title: "test"})
fmt.Fprint(w, string(foo_marshalled)) // write response to ResponseWriter (w)

In JavaScript:

// web call & receive in "data", thru Ajax/ other

var Foo = JSON.parse(data);
console.log("number: " + Foo.number);
console.log("title: " + Foo.title);

I found this question today, but I'm not sure why was this made so complicated rather than implementing it simply like:

var input = $('#target');
var inputVal = input.val();
input.on('change', function() {
  console.log('Current Value: ', $(this).val());
  console.log('Old Value: ', inputVal);
  inputVal = $(this).val();
});

If you want to target multiple inputs then, use each function:

$('input').each(function() {
  var inputVal = $(this).val();
  $(this).on('change', function() {
    console.log('Current Value: ',$(this).val());
    console.log('Old Value: ', inputVal);
    inputVal = $(this).val();
});

Many of the answers seem to me to be ignoring the stated requirements:

• The result should be a byte array
• It should be as efficient as possible

These two together rule out a LINQ sequence of bytes - anything with yield is going to make it impossible to get the final size without iterating through the whole sequence.

If those aren't the real requirements of course, LINQ could be a perfectly good solution (or the IList<T> implementation). However, I'll assume that Superdumbell knows what he wants.

(EDIT: I've just had another thought. There's a big semantic difference between making a copy of the arrays and reading them lazily. Consider what happens if you change the data in one of the "source" arrays after calling the Combine (or whatever) method but before using the result - with lazy evaluation, that change will be visible. With an immediate copy, it won't. Different situations will call for different behaviour - just something to be aware of.)

Here are my proposed methods - which are very similar to those contained in some of the other answers, certainly :)

public static byte[] Combine(byte[] first, byte[] second)
{
    byte[] ret = new byte[first.Length + second.Length];
    Buffer.BlockCopy(first, 0, ret, 0, first.Length);
    Buffer.BlockCopy(second, 0, ret, first.Length, second.Length);
    return ret;
}

public static byte[] Combine(byte[] first, byte[] second, byte[] third)
{
    byte[] ret = new byte[first.Length + second.Length + third.Length];
    Buffer.BlockCopy(first, 0, ret, 0, first.Length);
    Buffer.BlockCopy(second, 0, ret, first.Length, second.Length);
    Buffer.BlockCopy(third, 0, ret, first.Length + second.Length,
                     third.Length);
    return ret;
}

public static byte[] Combine(params byte[][] arrays)
{
    byte[] ret = new byte[arrays.Sum(x => x.Length)];
    int offset = 0;
    foreach (byte[] data in arrays)
    {
        Buffer.BlockCopy(data, 0, ret, offset, data.Length);
        offset += data.Length;
    }
    return ret;
}

Of course the "params" version requires creating an array of the byte arrays first, which introduces extra inefficiency.

'L' means wchar_t, which, as opposed to a normal character, requires 16-bits of storage rather than 8-bits. Here's an example:

"A"    = 41
"ABC"  = 41 42 43
L"A"   = 00 41
L"ABC" = 00 41 00 42 00 43

A wchar_t is twice big as a simple char. In daily use you don't need to use wchar_t, but if you are using windows.h you are going to need it.

This example works perfectly in Android

In kotlin you can use a lambda expression for this. The Kotlin Array Constructor definition is:

Array(size: Int, init: (Int) -> T)

Which evaluates to:

skillsSummaryDetailLinesArray = Array(linesLen) {
        i: Int -> skillsSummaryDetailLines!!.getString(i)
}

Or:

skillsSummaryDetailLinesArray = Array<String>(linesLen) {
        i: Int -> skillsSummaryDetailLines!!.getString(i)
}

In this example the field definition was:

private var skillsSummaryDetailLinesArray: Array<String>? = null

Hope this helps

Relative to the default size defined to that font.

If someone opens your page on a web browser, there's a default font and font size it uses.

This is not actually adding the CSS to the cell, but gives the same effect. While providing the same result as others above, this version is a little more intuitive to me, but I'm a novice, so take it for what it's worth:

$(".hoverCell").bind('mouseover', function() {
    var old_color = $(this).css("background-color");
    $(this)[0].style.backgroundColor = '#ffff00';

    $(".hoverCell").bind('mouseout', function () {
        $(this)[0].style.backgroundColor = old_color;
    });
});

This requires setting the Class for each of the cells you want to highlight to "hoverCell".

I had an issue with node.exe programs like test output with mocha.

In my case, I solved it by removing some default "node.exe" alias.

I'm using Git Bash for Windows(2.29.2) and some default aliases are set from /etc/profile.d/aliases.sh,

  # show me alias related to 'node'
  $ alias|grep node
  alias node='winpty node.exe'`

To remove the alias, update aliases.sh or simply do

unalias node

I don't know why winpty has this side effect on console.info buffered output but with a direct node.exe use, I've no more stdout issue.

If you are matching with sqlite database:
In your php folder open php.ini file, go to:

;extension=pdo_sqlite

Just remove the semicolon and it will work.

All you have to do is assign this property:

img {
    display: block;
}

The images by default have this property:

img {
    display: inline;
}

Check out the implode() function as an alternative. This will convert the array into a list. The first param is how you want the items separated. Here I have used a comma with a space after it.

$invite = implode(', ', $_POST['invite']);
echo $invite;

Had similar issue but the message was shown when I tried to open a project solution. What worked for me was:

TOOLS -> Import and Export Settings...-> Reset all settings

It could be the encoding of the special characters. You could ask json_last_error() to get definite information.

Update: The issue is solved, look at the "Solution" paragraph in the question.

Your code doesn't get the UTF-8 into memory as you read it back into a string again, so its no longer in UTF-8, but back in UTF-16 (though ideally its best to consider strings at a higher level than any encoding, except when forced to do so).

To get the actual UTF-8 octets you could use:

var serializer = new XmlSerializer(typeof(SomeSerializableObject));

var memoryStream = new MemoryStream();
var streamWriter = new StreamWriter(memoryStream, System.Text.Encoding.UTF8);

serializer.Serialize(streamWriter, entry);

byte[] utf8EncodedXml = memoryStream.ToArray();

I've left out the same disposal you've left. I slightly favour the following (with normal disposal left in):

var serializer = new XmlSerializer(typeof(SomeSerializableObject));
using(var memStm = new MemoryStream())
using(var  xw = XmlWriter.Create(memStm))
{
  serializer.Serialize(xw, entry);
  var utf8 = memStm.ToArray();
}

Which is much the same amount of complexity, but does show that at every stage there is a reasonable choice to do something else, the most pressing of which is to serialise to somewhere other than to memory, such as to a file, TCP/IP stream, database, etc. All in all, it's not really that verbose.

I have the same issue, when I try to export the content of email to csv and still keep it break line when importing to excel.

I export the conent as this: ="Line 1"&CHAR(10)&"Line 2"

When I import it to excel(google), excel understand it as string. It still not break new line.

We need to trigger excel to treat it as formula by: Format -> Number | Scientific.

This is not the good way but it resolve my issue.

It is quite evident that there is only a single id corresponding to a single username because username is unique.

But the actual problem lies in the query itself-

$sql = "SELECT 'id' FROM Users WHERE username='$name'";

O/P

+----+
| id |
+----+
| id |
+----+

i.e. 'id' actually is treated as a string not as the id attribute.

Correct synatx:

$sql = "SELECT `id` FROM Users WHERE username='$name'";

i.e. use grave accent(`) instead of single quote(').

or

$sql = "SELECT id FROM Users WHERE username='$name'";

Complete code

session_start();
$name = $_GET["username"];
$sql = "SELECT `id` FROM Users WHERE username='$name'";
$result = mysql_query($sql);
$row=mysql_fetch_array($result)
$value = $row[0];
$_SESSION['myid'] = $value;

I had to go look for ojdbc compatible with version on oracle that was installed this fixed my problem, my bad was thinking one ojdbc would work for all

You just have to define that Animal implements Comparable<Animal> i.e. public class Animal implements Comparable<Animal>. And then you have to implement the compareTo(Animal other) method that way you like it.

@Override
public int compareTo(Animal other) {
    return Integer.compare(this.year_discovered, other.year_discovered);
}

Using this implementation of compareTo, animals with a higher year_discovered will get ordered higher. I hope you get the idea of Comparable and compareTo with this example.

You can do:

def mul_table(n,i=1):
    print(n*i)
    if i !=10:
        mul_table(n,i+1)
mul_table(7)

In my case the bitmap image file already existed in the system drive, so my app threw the error "A Generic error occured in GDI+".

The working directory is a common concept across virtually all operating systems and program languages etc. It's the directory in which your program is running. This is usually (but not always, there are ways to change it) the directory the application is in.

Relative paths are ones that start without a drive specifier. So in linux they don't start with a /, in windows they don't start with a C:\, etc. These always start from your working directory.

Absolute paths are the ones that start with a drive (or machine for network paths) specifier. They always go from the start of that drive.

If none of the above help you out, and you have the option, try obtaining one of the rpm files eg:

wget http://rpms.famillecollet.com/enterprise/6/remi/x86_64/php-mbstring-5.4.45-2.el6.remi.x86_64.rpm

then using rpm, install it ignoring the depenecies like so:

rpm -i --nodeps php-mbstring-5.4.45-2.el6.remi.x86_64.rpm

Hope that helps out.

Don't waste your time trying to resolve this issue, this was made clear by the makers themselves. Instead of cv2.imshow() use this:

img = cv2.imread('path_to_image')
plt.imshow(img, cmap = 'gray', interpolation = 'bicubic')
plt.xticks([]), plt.yticks([])  # to hide tick values on X and Y axis
plt.show()

I installed the module by running the following from the directory with MANIFEST.in:

python setup.py install

Then, from a totally different location on my filesystem /moustache/armwrestle I was able to run:

import a
dir(a)

Which confirmed that a.cats indeed equalled 0 and a.b.dogs indeed equalled 1, as intended.

You can also use logical tests

x <- data.frame(a = c(0,1,2,NA), b = c(0,NA,1,2), c = c(NA, 0, 1, 2)) 
x
x$a <- replace(x$a, is.na(x$a), 0)
x
x$b <- replace(x$b, x$b==2, 333)

While searching for doc to point to about how pragma are directives for the compiler, I found this NSHipster article that does the job pretty well.

I hope you'll enjoy the reading

This is not directly to your code sample, but in general about the error. I'm writing it here, because Google directs this error to this question, so it may be useful for the other devs.

Another use case when you can receive such error is when you're adding a selector to method in another class, eg:

private class MockTextFieldTarget {
private(set) var didCallDoneAction = false
    @objc func doneActionHandler() {
        didCallDoneAction = true
    }
}

And then in another class:

final class UITextFieldTests: XCTestCase {
    func testDummyCode() {
        let mockTarget = MockTextFieldTarget()
        UIBarButtonItem(barButtonSystemItem: .cancel, target: mockTarget, action: MockTextFieldTarget.doneActionHandler)
        // ... do something ...
    }
}

If in the last line you'd simply call #selector(cancelActionHandler) instead of #selector(MockTextFieldTarget.cancelActionHandler), you'd get

use of unresolved identifier

error.

If you want to use a function form a package or module in python you have to import and reference them. For example normally you do the following to draw 5 points( [1,5],[2,4],[3,3],[4,2],[5,1]) in the space:

import matplotlib.pyplot
matplotlib.pyplot.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
matplotlib.pyplot.show()

In your solution

from matplotlib import*

This imports the package matplotlib and "plot is not defined" means there is no plot function in matplotlib you can access directly, but instead if you import as

from matplotlib.pyplot import *
plot([1,2,3,4,5],[5,4,3,2,1],"bx")
show()

Now you can use any function in matplotlib.pyplot without referencing them with matplotlib.pyplot.

I would recommend you to name imports you have, in this case you can prevent disambiguation and future problems with the same function names. The last and clean version of above example looks like:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
plt.show()

You are mixing mysqli and mysql function.

If your are using mysql function then instead mysqli_real_escape_string($your_variable); use

$username = mysql_real_escape_string($_POST['username']);
$pass = mysql_real_escape_string($_POST['pass']);
$pass1 = mysql_real_escape_string($_POST['pass1']);
$email = mysql_real_escape_string($_POST['email']);

If your using mysqli_* function then you have to include your connection to database into mysqli_real_escape function :

$username = mysqli_real_escape_string($your_connection, $_POST['username']);
$pass = mysqli_real_escape_string($your_connection, $_POST['pass']);
$pass1 = mysqli_real_escape_string($your_connection, $_POST['pass1']);
$email = mysqli_real_escape_string($your_connection, $_POST['email']);

Note : Use mysqli_* function since mysql has been deprecated. For information please read mysqli_*

With stringquery Package:

import qs from "stringquery";

const obj = qs("?status=APPROVED&page=1limit=20");  
// > { limit: "10", page:"1", status:"APPROVED" }

With query-string Package:

import qs from "query-string";
const obj = qs.parse(this.props.location.search);
console.log(obj.param); // { limit: "10", page:"1", status:"APPROVED" } 

No Package:

const convertToObject = (url) => {
  const arr = url.slice(1).split(/&|=/); // remove the "?", "&" and "="
  let params = {};

  for(let i = 0; i < arr.length; i += 2){
    const key = arr[i], value = arr[i + 1];
    params[key] = value ; // build the object = { limit: "10", page:"1", status:"APPROVED" }
  }
  return params;
};


const uri = this.props.location.search; // "?status=APPROVED&page=1&limit=20"

const obj = convertToObject(uri);

console.log(obj); // { limit: "10", page:"1", status:"APPROVED" }


// obj.status
// obj.page
// obj.limit

Hope that helps :)

Happy coding!

I had this problem while trying to mix figures and text. What worked for me was the 'H' option without the '!' option. \begin{figure}[H]
'H' tries to forces the figure to be exactly where you put it in the code. This requires you include \usepackage{float}

The options are explained here

As others have pointed out, thread safety means that a piece of code will work without errors if it's used by more than one thread at once.

It's worth being aware that this sometimes comes at a cost, of computer time and more complex coding, so it isn't always desirable. If a class can be safely used on only one thread, it may be better to do so.

For example, Java has two classes that are almost equivalent, StringBuffer and StringBuilder. The difference is that StringBuffer is thread-safe, so a single instance of a StringBuffer may be used by multiple threads at once. StringBuilder is not thread-safe, and is designed as a higher-performance replacement for those cases (the vast majority) when the String is built by only one thread.

I feel like all that was wrong here was the order, Selçuklu wanted the app to wait for a second before filling in the grid, so the Sleep command should have come before the fill command.

    System.Threading.Thread.Sleep(1000);
    dataGridView1.Rows[x1].Cells[y1].Style.BackColor = System.Drawing.Color.Red;

Another possible reason for this problem is that your OS runs python3 by default.

Either you have to explicitly do: python2 manage.py

or you need to edit the shebang of manage.py, like so:

#!/usr/bin/env python2

or if you are using python3:

#!/usr/bin/env python3

Simplification from the above Andrew's answer leads to this key theme to generate the half border.

theme (panel.border = element_blank(),
       axis.line    = element_line(color='black'))

Well all of the above answers are pretty good but here is a small simple function I whipped up. It works pretty well.

function hasClass(el, cn){
    var classes = el.classList;
    for(var j = 0; j < classes.length; j++){
        if(classes[j] == cn){
            return true;
        }
    }
}

Something like this substitutions will be needed for your tables and field names.

Declare @TableUsers Table (User_ID, MyRowCount Int Identity(1,1)
Declare @i Int, @MaxI Int, @UserID nVarchar(50)

Insert into @TableUser
Select User_ID
From Users 
Where (My Criteria)
Select @MaxI = @@RowCount, @i = 1

While @i <= @MaxI
Begin
Select @UserID = UserID from @TableUsers Where MyRowCount = @i
Exec prMyStoredProc @UserID
Select

 @i = @i + 1, @UserID = null
End

if (isset($_POST['Register']))
    {
        $ErrorArrays = array (); //Empty array for input errors 

        $Input_Username = $_POST['Username'];
        $Input_Password = $_POST['Password'];
        $Input_Confirm = $_POST['ConfirmPass'];
        $Input_Email = $_POST['Email'];

        if (empty($Input_Username))
        {
            $ErrorArrays[] = "Username Is Empty";
        }
        if (empty($Input_Password))
        {
            $ErrorArrays[] = "Password Is Empty";
        }
        if ($Input_Password !== $Input_Confirm)
        {
            $ErrorArrays[] = "Passwords Do Not Match!";
        }
        if (!filter_var($Input_Email, FILTER_VALIDATE_EMAIL))
        {
            $ErrorArrays[] = "Incorrect Email Formatting";
        }

        if (count($ErrorArrays) == 0)
        {
            // No Errors
        }
        else
        {
            foreach ($ErrorArrays AS $Errors)
            {
                echo "<font color='red'><b>".$Errors."</font></b><br>";
            }
        }
    }

?>

    <form method="POST"> 
        Username: <input type='text' name='Username'> <br>
        Password: <input type='password' name='Password'><br>
        Confirm Password: <input type='password' name='ConfirmPass'><br>
        Email: <input type='text' name='Email'> <br><br>

        <input type='submit' name='Register' value='Register'>


    </form> 

This is a very basic PHP Form validation. This could be put in a try block, but for basic reference, I see this fit following our conversation in the comment box.

What this script will do, is process each of the post elements, and act accordingly, for example:

    if (!filter_var($Input_Email, FILTER_VALIDATE_EMAIL))
        {
            $ErrorArrays[] = "Incorrect Email Formatting";
        }

This will check:

if $Input_Email is not a valid email. If this is not a valid E-mail, then a message will get added to a empty array.

Further down the script, you will see:

    if (count($ErrorArrays) == 0)
    {
        // No Errors
    }
    else
    {
        foreach ($ErrorArrays AS $Errors)
        {
            echo "<font color='red'><b>".$Errors."</font></b><br>";
        }
    }

Basically. if the array count is not 0, errors have been found. Then the script will print out the errors.

Remember, this is a reference based on our conversation in the comment box, and should be used as such.

No, there is absolutely nothing wrong with using the ! operator in if..then..else statements.

The naming of variables, and in your example, methods is what is important. If you are using:

if(!isPerson()) { ... } // Nothing wrong with this

However:

if(!balloons()) { ... } // method is named badly

It all comes down to readability. Always aim for what is the most readable and you won't go wrong. Always try to keep your code continuous as well, for instance, look at Bill the Lizards answer.

You can use colorRampPalette from base or RColorBrewer package:

With colorRampPalette, you can specify colours as follows:

colorRampPalette(c("red", "green"))(5)
# [1] "#FF0000" "#BF3F00" "#7F7F00" "#3FBF00" "#00FF00"

You can alternatively provide hex codes as well:

colorRampPalette(c("#3794bf", "#FFFFFF", "#df8640"))(5)
# [1] "#3794BF" "#9BC9DF" "#FFFFFF" "#EFC29F" "#DF8640"
# Note that the mid color is the mid value...

With RColorBrewer you could use colors from pre-existing palettes:

require(RColorBrewer)
brewer.pal(9, "Set1")
# [1] "#E41A1C" "#377EB8" "#4DAF4A" "#984EA3" "#FF7F00" "#FFFF33" "#A65628" "#F781BF"
# [9] "#999999"

Look at RColorBrewer package for other available palettes. Hope this helps.

SELECT terms.*
FROM terms JOIN terms_relation ON id=term_id
WHERE taxonomy='categ'

perl -lne '$x += $_; END { print $x; }' < infile.txt

I had a similar goal - and came to this solution:

select *
from jobdetails as JD
where not exists ( select code from table_of_codes as TC 
                      where JD.job_no like TC.code ) 

I'm assuming that your various codes ('0711%', '0712%', etc), including the %, are stored in a table, which I'm calling *table_of_codes*, with field code.

If the % is not stored in the table of codes, just concatenate the '%'. For example:

select *
from jobdetails as JD
where not exists ( select code from table_of_codes as TC 
                      where JD.job_no like concat(TC.code, '%') ) 

The concat() function may vary depending on the particular database, as far as I know.

I hope that it helps. I adapted it from:

http://us.generation-nt.com/answer/subquery-wildcards-help-199505721.html

You can't easily do this in a generic way: you can only convert an integer to a specific type of enum. As Nicholas has shown, this is a trivial cast if you only care about one kind of enum, but if you want to write a generic method that can handle different kinds of enums, things get a bit more complicated. You want a method along the lines of:

public static string GetEnumDescription<TEnum>(int value)
{
  return GetEnumDescription((Enum)((TEnum)value));  // error!
}

but this results in a compiler error that "int can't be converted to TEnum" (and if you work around this, that "TEnum can't be converted to Enum"). So you need to fool the compiler by inserting casts to object:

public static string GetEnumDescription<TEnum>(int value)
{
  return GetEnumDescription((Enum)(object)((TEnum)(object)value));  // ugly, but works
}

You can now call this to get a description for whatever type of enum is at hand:

GetEnumDescription<MyEnum>(1);
GetEnumDescription<YourEnum>(2);

I came up with the solution and posted it on my blog

http://web.archive.org/web/20130310123646/http://onlinemarketingexperts.com.au/2013/01/how-to-permanently-redirect-301-all-404-missing-pages-in-htaccess/

here is the htaccess code also

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . / [L,R=301]

but I posted other solutions on my blog too, it depends what you need really

When I align elements in center I use the bootstrap class text-center:

<div class="text-center">Centered content goes here</div>

bool b = list.Contains("Hello", StringComparer.CurrentCultureIgnoreCase);

[EDIT] extension code:

public static bool Contains(this string source, string cont
                                                    , StringComparison compare)
{
    return source.IndexOf(cont, compare) >= 0;
}

This could work :)

you can use this command by getting your data. this will extract your data...

select * from employees where to_char(es_date,'dd/mon/yyyy')='17/jun/2003';

EncodedParams variable is redefined as params variable will not work. You need to have same predefined call to variable, otherwise it looks possible with a little more work. Cheers! json is not used to its full capabilities in php there are better ways to call json which I don't recall at the moment.

latest is really designed to work with date fields (it probably does work with other total-ordered types too, but not sure). And the only way you can use it without specifying the field name is by setting the get_latest_by meta attribute, as mentioned here.

Here you can find all hadoop shell commands:

deleting: rmr Usage: hadoop fs -rmr URI [URI …]

Recursive version of delete.

Example:

hadoop fs -rmr /user/hadoop/dir
hadoop fs -rmr hdfs://nn.example.com/user/hadoop/dir

Exit Code:

Returns 0 on success and -1 on error.

• System properties are set on the Java command line using the -Dpropertyname=value syntax. They can also be added at runtime using System.setProperty(String key, String value) or via the various System.getProperties().load() methods.
  To get a specific system property you can use System.getProperty(String key) or System.getProperty(String key, String def).

• Environment variables are set in the OS, e.g. in Linux export HOME=/Users/myusername or on Windows SET WINDIR=C:\Windows etc, and, unlike properties, may not be set at runtime.
  To get a specific environment variable you can use System.getenv(String name).

$this->db->where_in('id', ['20','15','22','42','86']);

Reference: where_in

In case someone google for this, the solutions above didn't work for me so i ended using "pure" javascript

document.getElementById("The id of the element").value = "The value"

And that would set the value and make the current value selected in the combo box. Tested in firefox.

it was easier than keep googling a solution for jQuery

A String is an object in Java.

you could compare like so,

if(this.lastName.compareTo(s.getLastName() == 0)//last names are the same

You sure can.

protected void GetColumNames_DataReader()
{
  System.Data.SqlClient.SqlConnection SqlCon = new System.Data.SqlClient.SqlConnection("server=localhost;database=northwind;trusted_connection=true");
  System.Data.SqlClient.SqlCommand SqlCmd = new System.Data.SqlClient.SqlCommand("SELECT * FROM Products", SqlCon);

  SqlCon.Open();

  System.Data.SqlClient.SqlDataReader SqlReader = SqlCmd.ExecuteReader();
  System.Int32 _columncount = SqlReader.FieldCount;

  System.Web.HttpContext.Current.Response.Write("SqlDataReader Columns");
  System.Web.HttpContext.Current.Response.Write(" ");

  for ( System.Int32 iCol = 0; iCol < _columncount; iCol ++ )
  {
    System.Web.HttpContext.Current.Response.Write("Column " + iCol.ToString() + ": ");
    System.Web.HttpContext.Current.Response.Write(SqlReader.GetName( iCol ).ToString());
    System.Web.HttpContext.Current.Response.Write(" ");
  }

This article helped me alot figuring out why it wasn't working for me either. It give me a lesson to think of the webpage loading and how angular 2 interacts as a timeline and not just the point in time i'm thinking of. I didn't see anyone else mention this point, so I will...

The reason the *ngIf is needed because it will try to check the length of that variable before the rest of the OnInit stuff happens, and throw the "length undefined" error. So thats why you add the ? because it won't exist yet, but it will soon.

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

This is not exactly what you asked for, but for http(s):

• you can put the password in .netrc file (_netrc on windows). From there it would be picked up automatically. It would go to your home folder with 600 permissions.
• you could also just clone the repo with https://user:pass@domain/repo but that's not really recommended as it would show your user/pass in a lot of places...
• a new option is to use the credential helper. Note that credentials would be stored in clear text in your local config using standard credential helper. credential-helper with wincred can be also used on windows.

Usage examples for credential helper

• git config credential.helper store - stores the credentials indefinitely.
• git config credential.helper 'cache --timeout=3600'- stores for 60 minutes

For ssh-based access, you'd use ssh agent that will provide the ssh key when needed. This would require generating keys on your computer, storing the public key on the remote server and adding the private key to relevant keystore.

Yet another way: if you are working with a C string, e.g. const char *, C native atoi() is more convenient.

You seem to be doing file name comparisons, so I would just add that OrdinalIgnoreCase is closest to what NTFS does (it's not exactly the same, but it's closer than InvariantCultureIgnoreCase)

This solution does not work correctly in some situations.
So I extend it:

FontsReplacer.java

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        FontsReplacer.replaceFonts(this);
        super.onCreate();
    }

}

https://gist.github.com/orwir/6df839e3527647adc2d56bfadfaad805

Without the 0b in front:

"{0:b}".format(int)

Starting with Python 3.6 you can also use formatted string literal or f-string, --- PEP:

f"{int:b}"

You're missing a required space between the bracket and -e:

#!/bin/bash
if [ -e x.txt ]
then
    echo "ok"
else
    echo "nok"
fi

From client side, I cant solve this problem. From nodejs express side, you can use cors module to handle it.

var express       = require('express');
var app           = express();
var bodyParser = require('body-parser');
var cors = require('cors');

var port = 3000; 
var ip = '127.0.0.1';

app.use('*/myapi', 
          cors(), // with this row OPTIONS has handled
          bodyParser.text({type:'text/*'}),
          function( req, res, next ){
    console.log( '\n.----------------' + req.method + '------------------------' );
        console.log( '| prot:'+req.protocol );
        console.log( '| host:'+req.get('host') );
        console.log( '| url:'+req.originalUrl );
        console.log( '| body:',req.body );
        //console.log( '| req:',req );
    console.log( '.----------------' + req.method + '------------------------' );
    next();
    });

app.listen(port, ip, function() {
    console.log('Listening to port:  ' + port );
});
 
console.log(('dir:'+__dirname ));
console.log('The server is up and running at http://'+ip+':'+port+'/');

Without cors() this OPTIONS has appears before POST.

.----------------OPTIONS------------------------
| prot:http
| host:localhost:3000
| url:/myapi
| body: {}
.----------------OPTIONS------------------------

.----------------POST------------------------
| prot:http
| host:localhost:3000
| url:/myapi
| body: <SOAP-ENV:Envelope .. P-ENV:Envelope>
.----------------POST------------------------

The ajax call:

$.ajax({
    type: 'POST',
    contentType: "text/xml; charset=utf-8",
// these does not works
    //beforeSend: function(request) { 
    //  request.setRequestHeader('Content-Type', 'text/xml; charset=utf-8');
    //  request.setRequestHeader('Accept', 'application/vnd.realtime247.sct-giro-v1+cms');
    //  request.setRequestHeader('Access-Control-Allow-Origin', '*');
    //  request.setRequestHeader('Access-Control-Allow-Methods', 'POST, GET');
    //  request.setRequestHeader('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type');
    //},
    //headers: {
    //  'Content-Type': 'text/xml; charset=utf-8',

    //  'Access-Control-Allow-Methods': 'POST, GET',
    //  'Access-Control-Allow-Headers': 'Origin, X-Requested-With, Content-Type'
    //},
    url: 'http://localhost:3000/myapi',             
    data:       '<SOAP-ENV:Envelope .. P-ENV:Envelope>',                
    success: function( data ) {
      console.log(data.documentElement.innerHTML);
    },
    error: function(jqXHR, textStatus, err) {
      console.log( jqXHR,'\n', textStatus,'\n', err )
    }
  });

This is my edited version : you just need to add an extra argument "autoClose".

example :

 $('input[name="fieldName"]').datepicker({ autoClose: true});

also you can specify a close callback if you want. :)

replace datepicker.js with this:

!function( $ ) {

// Picker object

var Datepicker = function(element, options , closeCallBack){
    this.element = $(element);
    this.format = DPGlobal.parseFormat(options.format||this.element.data('date-format')||'dd/mm/yyyy');
    this.autoClose = options.autoClose||this.element.data('date-autoClose')|| true;
    this.closeCallback = closeCallBack || function(){};
    this.picker = $(DPGlobal.template)
                        .appendTo('body')
                        .on({
                            click: $.proxy(this.click, this)//,
                            //mousedown: $.proxy(this.mousedown, this)
                        });
    this.isInput = this.element.is('input');
    this.component = this.element.is('.date') ? this.element.find('.add-on') : false;

    if (this.isInput) {
        this.element.on({
            focus: $.proxy(this.show, this),
            //blur: $.proxy(this.hide, this),
            keyup: $.proxy(this.update, this)
        });
    } else {
        if (this.component){
            this.component.on('click', $.proxy(this.show, this));
        } else {
            this.element.on('click', $.proxy(this.show, this));
        }
    }

    this.minViewMode = options.minViewMode||this.element.data('date-minviewmode')||0;
    if (typeof this.minViewMode === 'string') {
        switch (this.minViewMode) {

You can use git cherry-pick for this. 'cherry-pick' will apply a commit onto the branch your on now.

then do

git rebase --hard <SHA1 of A>

then apply the D and E commits.

git cherry-pick <SHA1 of D>
git cherry-pick <SHA1 of E>

This will skip out the B and C commit. Having said that it might be impossible to apply the D commit to the branch without B, so YMMV.

You have to account for all values in the pivot set. you can accomplish this using a cartesian product.

select pivoted.*
from (
    select cartesian.key1, cartesian.key2, isnull(relationship.[value],'nullvalue') as [value]
    from (
      select k1.key1, k2.key2
      from ( select distinct key1 from relationship) k1
          ,( select distinct key2 from relationship) k2
    ) cartesian
      left outer join relationship on relationship.key1 = cartesian.key1 and  relationship.key2 = carterisan.key2
) data
  pivot (
    max(data.value) for ([key2_v1], [key2_v2], [key2_v3], ...)
  ) pivoted

You also can use in this form:

<a href="@Url.Action("Information", "Admin", null)"> Admin</a>

find . -name '*.pyc' -print0 | xargs -0 rm

The find recursively looks for *.pyc files. The xargs takes that list of names and sends it to rm. The -print0 and the -0 tell the two commands to seperate the filenames with null characters. This allows it to work correctly on file names containing spaces, and even a file name containing a new line.

The solution with -exec works, but it spins up a new copy of rm for every file. On a slow system or with a great many files, that'll take too long.

You could also add a couple more args:

find . -iname '*.pyc' -print0 | xargs -0 --no-run-if-empty  rm

iname adds case insensitivity, like *.PYC . The no-run-if-empty keeps you from getting an error from rm if you have no such files.

try using

background-color: none;

that worked for me.

You might want to consider using a div element pop-up window that contains an iframe.

jQuery Dialog is a simple way to get started. Just add an iframe as the content.

Given your specs, I'd use slice-assignment:

>>> L = ['title', 'email', 'password2', 'password1', 'first_name', 'last_name', 'next', 'newsletter']
>>> i = L.index('password2')
>>> L[i:i+2] = L[i+1:i-1:-1]
>>> L
['title', 'email', 'password1', 'password2', 'first_name', 'last_name', 'next', 'newsletter']

The right-hand side of the slice assignment is a "reversed slice" and could also be spelled:

L[i:i+2] = reversed(L[i:i+2])

if you find that more readable, as many would.

iOS 5 has support for position:fixed.

For everyone saying to get the bytes, copy it to MemoryStream, etc. - if the content isn't expected to be larger than computer's memory should be reasonably be expected to allow, why not just use StreamReader's built in ReadLine() or ReadToEnd()? I saw these weren't even mentioned, and they do everything for you.

I had a use-case where I just wanted to store the path of a SQLite file from a FileDialogResult that the user picks during the synching/initialization process. My program then later needs to use this path when it is run for normal application processes. Maybe not the ideal way to capture/re-use the information, but it's not much different than writing to/reading from an .ini file - I just didn't want to set one up for one value. So I just read it from a flat, one-line text file. Here's what I did:

string filePath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
if (!filePath.EndsWith(@"\")) temppath += @"\"; // ensures we have a slash on the end
filePath = filePath.Replace(@"\\", @"\"); // Visual Studio escapes slashes by putting double-slashes in their results - this ensures we don't have double-slashes
filePath += "SQLite.txt";

string path = String.Empty;
FileStream fs = new FileStream(filePath, FileMode.Open);
StreamReader sr = new StreamReader(fs);
path = sr.ReadLine();  // can also use sr.ReadToEnd();
sr.Close();
fs.Close();
fs.Flush();

return path;

If you REALLY need a byte[] instead of a string for some reason, using my example, you can always do:

byte[] toBytes;
FileStream fs = new FileStream(filePath, FileMode.Open);
StreamReader sr = new StreamReader(fs);
toBytes = Encoding.ASCII.GetBytes(path);
sr.Close();
fs.Close();
fs.Flush();

return toBytes;

(Returning toBytes instead of path.)

If you don't want ASCII you can easily replace that with UTF8, Unicode, etc.

There exist breakpoint() method nowadays, which replaces import pdb; pdb.set_trace().

It also has several new features, such as possible environment variables.

I found some answers, but I don't know if it is the right way.This is my solution for now. Fortunatelly it didn´t broke my design mode.

    `
    /// <summary>
    /// set config, if key is not in file, create
    /// </summary>
    /// <param name="key">Nome do parâmetro</param>
    /// <param name="value">Valor do parâmetro</param>
    public static void SetConfig(string key, string value)
    {
        var configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        var settings = configFile.AppSettings.Settings;
        if (settings[key] == null)
        {
            settings.Add(key, value);
        }
        else
        {
            settings[key].Value = value;
        }
        configFile.Save(ConfigurationSaveMode.Modified);
        ConfigurationManager.RefreshSection(configFile.AppSettings.SectionInformation.Name);
    }

    /// <summary>
    /// Get key value, if not found, return null
    /// </summary>
    /// <param name="key"></param>
    /// <returns>null if key is not found, else string with value</returns>
    public static string GetConfig(string key)
    {
        return ConfigurationManager.AppSettings[key];
    }`

Here is the same style as in large datasets:

x = df[:5]
y = pd.DataFrame([['...']*df.shape[1]], columns=df.columns, index=['...'])
z = df[-5:]
frame = [x, y, z]
result = pd.concat(frame)

print(result)

Output:

I started a bit more systematic listing of what values you can expect using the various modules (feel free to edit and add your system):

• tried with archlinux and mint, got same results
• on python2 sys.platform is suffixed by kernel version, e.g. linux2, everything else stays identical
• same output on Windows Subsystem for Linux (tried with ubuntu 18.04 LTS), except platform.architecture() = ('64bit', 'ELF')

Some remarks:

• there is also distutils.util.get_platform() which is identical to `sysconfig.get_platform
• anaconda on windows is same as official python windows installer
• I don't have a Mac nor a true 32bit system and was not motivated to do it online

To compare with your system, simply run this script (and please append results here if missing :)

from __future__ import print_function
import os
import sys
import platform
import sysconfig

print("os.name                      ",  os.name)
print("sys.platform                 ",  sys.platform)
print("platform.system()            ",  platform.system())
print("sysconfig.get_platform()     ",  sysconfig.get_platform())
print("platform.machine()           ",  platform.machine())
print("platform.architecture()      ",  platform.architecture())

move and del ARE certainly the equivalents, but from a functionality standpoint they are woefully NOT equivalent. For example, you can't move both files AND folders (in a wildcard scenario) with the move command. And the same thing applies with del.

The preferred solution in my view is to use Win32 ports of the Linux tools, the best collection of which I have found being here.

mv and rm are in the CoreUtils package and they work wonderfully!

If the file is large, you may not want to load it entirely into memory at once. This approach avoids that. (Of course, making a dict out of it could still take up some RAM, but it's guaranteed to be smaller than the original file.)

my_dict = {}
for i, line in enumerate(file):
    if (i - 8) % 7:
        continue
    k, v = line.split("\t")[:3:2]
    my_dict[k] = v

Edit: Not sure where I got extend from before. I meant update

Nice shorthand for Multiple variable assignments

{% set label_cls, field_cls = "col-md-7", "col-md-3" %}

Just in case somebody ist still coming along this question:

There is a body query object in any request. You do not need to parse it yourself.

E.g. if you want to send an accessToken from a client with GET, you could do it like this:

const request = require('superagent');_x000D_
_x000D_
request.get(`http://localhost:3000/download?accessToken=${accessToken}`).end((err, res) => {_x000D_
  if (err) throw new Error(err);_x000D_
  console.log(res);_x000D_
});

The server request object then looks like {request: { ... query: { accessToken: abcfed } ... } }

The above answers won't let you quote inside the quotes. This solution will:

sudo -su nobody umask 0000 \; mkdir -p "$targetdir"

Both the umask command and the mkdir-command runs in with the 'nobody' user.

Here's a nice 2013 update using FastMember from NuGet:

IEnumerable<SomeType> data = ...
DataTable table = new DataTable();
using(var reader = ObjectReader.Create(data)) {
    table.Load(reader);
}

This uses FastMember's meta-programming API for maximum performance. If you want to restrict it to particular members (or enforce the order), then you can do that too:

IEnumerable<SomeType> data = ...
DataTable table = new DataTable();
using(var reader = ObjectReader.Create(data, "Id", "Name", "Description")) {
    table.Load(reader);
}

Editor's Dis/claimer: FastMember is a Marc Gravell project. It's gold and full-on flies!

Yes, this is pretty much the exact opposite of this one; reflection would suffice - or if you need quicker, HyperDescriptor in 2.0, or maybe Expression in 3.5. Actually, HyperDescriptor should be more than adequate.

For example:

// remove "this" if not on C# 3.0 / .NET 3.5
public static DataTable ToDataTable<T>(this IList<T> data)
{
    PropertyDescriptorCollection props =
        TypeDescriptor.GetProperties(typeof(T));
    DataTable table = new DataTable();
    for(int i = 0 ; i < props.Count ; i++)
    {
        PropertyDescriptor prop = props[i];
        table.Columns.Add(prop.Name, prop.PropertyType);
    }
    object[] values = new object[props.Count];
    foreach (T item in data)
    {
        for (int i = 0; i < values.Length; i++)
        {
            values[i] = props[i].GetValue(item);
        }
        table.Rows.Add(values);
    }
    return table;        
}

Now with one line you can make this many many times faster than reflection (by enabling HyperDescriptor for the object-type T).

Edit re performance query; here's a test rig with results:

Vanilla 27179
Hyper   6997

I suspect that the bottleneck has shifted from member-access to DataTable performance... I doubt you'll improve much on that...

Code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
public class MyData
{
    public int A { get; set; }
    public string B { get; set; }
    public DateTime C { get; set; }
    public decimal D { get; set; }
    public string E { get; set; }
    public int F { get; set; }
}

static class Program
{
    static void RunTest(List<MyData> data, string caption)
    {
        GC.Collect(GC.MaxGeneration, GCCollectionMode.Forced);
        GC.WaitForPendingFinalizers();
        GC.WaitForFullGCComplete();
        Stopwatch watch = Stopwatch.StartNew();
        for (int i = 0; i < 500; i++)
        {
            data.ToDataTable();
        }
        watch.Stop();
        Console.WriteLine(caption + "\t" + watch.ElapsedMilliseconds);
    }
    static void Main()
    {
        List<MyData> foos = new List<MyData>();
        for (int i = 0 ; i < 5000 ; i++ ){
            foos.Add(new MyData
            { // just gibberish...
                A = i,
                B = i.ToString(),
                C = DateTime.Now.AddSeconds(i),
                D = i,
                E = "hello",
                F = i * 2
            });
        }
        RunTest(foos, "Vanilla");
        Hyper.ComponentModel.HyperTypeDescriptionProvider.Add(
            typeof(MyData));
        RunTest(foos, "Hyper");
        Console.ReadLine(); // return to exit        
    }
}

If you want to format your table via kable, you can use row.names = F

kable(df, row.names = F)

Looks like you got what you need from @matt, but if you want a quick way to get a value for a key, or just the first value if that key doesn’t exist:

extension Dictionary {
    func keyedOrFirstValue(key: Key) -> Value? {
        // if key not found, replace the nil with 
        // the first element of the values collection
        return self[key] ?? first(self.values)
        // note, this is still an optional (because the
        // dictionary could be empty)
    }
}

let d = ["one":"red", "two":"blue"]

d.keyedOrFirstValue("one")  // {Some "red"}
d.keyedOrFirstValue("two")  // {Some "blue"}
d.keyedOrFirstValue("three")  // {Some "red”}

Note, no guarantees what you'll actually get as the first value, it just happens in this case to return “red”.

I couldn't get any of these suggestions to work with nUnit 2.5.10 so I ended up using nUnit's Project -> Edit functionality to specify the config file to target (as others have said it needs to be in the same folder as the .nunit file itself). The positive side of this is that I can give the config file a Test.config name which makes it much clearer what it is and why it is)

Well @sonida's answer helped me but Here I am posting complete step How I did it.

Change Mobile Device Settings:

1. Unplug the device from the computer
2. Go to Mobile Settings -> Storage.
3. In the ActionBar, click the option menu and choose "USB computer connection".
4. Check "Camera (PTP)" connection.

Download Google USB Driver:

5 .Now go to http://developer.android.com/sdk/win-usb.html#top and download USB Drivers --> unzip folder.

Install USB Drivers and Get Connected Device:

6.Then Right click on My computer -->Manage --> Device Manager.

7.You should seed Nexus 5 in the list.

8.Right click on Nexus 5 --> Update Driver Software... --> Browse my computer for driver software

9.select the folder we downloaded/unzipped "latest_usb_driver_windows" and Next ...Ok.

10.Now you will see pop-up dialogue asking for Allow device --> Ok.

11 .That's it!! device is connected now, you can see in DDMS.

Hope this will help someone.

I got this error and i fixed the issue with iconv function like following:

iconv('latin5', 'utf-8', $data['index']);

NumPy is not just more efficient; it is also more convenient. You get a lot of vector and matrix operations for free, which sometimes allow one to avoid unnecessary work. And they are also efficiently implemented.

For example, you could read your cube directly from a file into an array:

x = numpy.fromfile(file=open("data"), dtype=float).reshape((100, 100, 100))

Sum along the second dimension:

s = x.sum(axis=1)

Find which cells are above a threshold:

(x > 0.5).nonzero()

Remove every even-indexed slice along the third dimension:

x[:, :, ::2]

Also, many useful libraries work with NumPy arrays. For example, statistical analysis and visualization libraries.

Even if you don't have performance problems, learning NumPy is worth the effort.

#include<stdio.h>
#define n 3
struct body
{
    double p[3];//position
    double v[3];//velocity
    double a[3];//acceleration
    double radius;
    double mass;
};

struct body bodies[n];

int main()
{
    int a, b;
     for(a = 0; a < n; a++)
     {
            for(b = 0; b < 3; b++)
            {
                bodies[a].p[b] = 0;
                bodies[a].v[b] = 0;
                bodies[a].a[b] = 0;
            }
            bodies[a].mass = 0;
            bodies[a].radius = 1.0;
     }

    return 0;
}

this works fine. your question was not very clear by the way, so match the layout of your source code with the above.

My solution,

function isNumeric(input) {
    var number = /^\-{0,1}(?:[0-9]+){0,1}(?:\.[0-9]+){0,1}$/i;
    var regex = RegExp(number);
    return regex.test(input) && input.length>0;
}

It appears to work in every situation, but I might be wrong.

You'll need at least C++11.

#include <thread>
#include <chrono>

...

std::this_thread::sleep_for(std::chrono::milliseconds(200));

I'm probably a bit late to the party, but I wrote the junitcategorizer for my thesis project at TOPdesk. Earlier versions indeed used a company internal Parent POM. So your problems are caused by the Parent POM not being resolvable, since it is not available to the outside world.

You can either:

• Remove the <parent> block, but then have to configure the Surefire, Compiler and other plugins yourself
• (Only applicable to this specific case!) Change it to point to our Open Source Parent POM by setting:

<parent>
    <groupId>com.topdesk</groupId>
    <artifactId>open-source-parent</artifactId>
    <version>1.2.0</version>
</parent>

If there's a possibility that the to be written file already exists and is read only, use the following code:

ATTRIB -R filename.ext
CD .>filename.ext

If no file exists, simply do:

CD .>filename.ext

(updated/changed code according to DodgyCodeException's comment)

To supress any errors that may arise:

ATTRIB -R filename.ext>NUL
(CD .>filename.ext)2>NUL

Since I didn't see this in any of the other answers, and since it's more efficient (in lines of code and in speed), here's a solution in VB.NET using a stringbuilder and lambda functions with String.Join instead of For loops for the columns.

Dim sb As New StringBuilder
sb.Append("<table>")
sb.Append("<tr>" & String.Join("", dt.Columns.OfType(Of DataColumn)().Select(Function(x) "<th>" & x.ColumnName & "</th>").ToArray()) & "</tr>")
For Each row As DataRow In dt.Rows
    sb.Append("<tr>" & String.Join("", row.ItemArray.Select(Function(f) "<td>" & f.ToString() & "</td>")) & "</tr>")
Next
sb.Append("</table>")

You can add your own styles to this pretty easily.

Just a note that the currently accepted answer is deprecated in Rails 3. You should do this instead:

Comment.where(:created_at => @selected_date.beginning_of_day..@selected_date.end_of_day)

Or, if you want to or have to use pure string conditions, you can do:

Comment.where('created_at BETWEEN ? AND ?', @selected_date.beginning_of_day, @selected_date.end_of_day)

When writing queries with our server LIKE or INSTR (or CHARINDEX in T-SQL) takes too long, so we use LEFT like in the following structure:

select *
from little
left join big
on left( big.key, len(little.key) ) = little.key

I understand that might only work with varying endings to the query, unlike other suggestions with '%' + b + '%', but is enough and much faster if you only need b+'%'.

Another way to optimize it for speed (but not memory) is to create a column in "little" that is "len(little.key)" as "lenkey" and user that instead in the query above.

Answer is very straight forward :

First take a backup of folder bootstrap/cache.

Then delete all the files from bootstrap/cache folder .

Now run:

php artisan migrate 

I had this similar problem in a coding competition and this is how I handled it. Setting a precision of 2 to all double values

First adding the header to use setprecision

#include <iomanip>

Then adding the following code in our main

  double answer=5.9999;
  double answer2=5.0000;
  cout<<setprecision(2)<<fixed;
  cout <<answer << endl;
  cout <<answer2 << endl;

Output:

5.99
5.00

You need to use fixed for writing 5.00 thats why,your output won't come for 5.00.

A short reference video link I'm adding which is helpful

in Windows, you can use the runas command. For linux users, there are some alternatives for sudo in windows, you can check this out

http://helpdeskgeek.com/free-tools-review/5-windows-alternatives-linux-sudo-command/

{{ word|striptags('<b>,<a>,<pre>')|raw }}

if you want to allow multiple tags

You can easily center multiple things by creating a chain. It works both vertically and horizontally

You have the horizontal chain : first_score <=> second_score <=> third_score. second_score is centered vertically. The other scores are centered vertically according to it.

You can definitely create a vertical chain first_score <=> subtitle and center it according to second_score

Using jQuery:

$(function() {
    window.isActive = true;
    $(window).focus(function() { this.isActive = true; });
    $(window).blur(function() { this.isActive = false; });
    showIsActive();
});

function showIsActive()
{
    console.log(window.isActive)
    window.setTimeout("showIsActive()", 2000);
}

function doWork()
{
    if (window.isActive) { /* do CPU-intensive stuff */}
}

If anyone using MS SQL Server 2008 and higher lands on this question: SQL Server 2008 and higher has a new "hierarchyId" feature designed specifically for this task.

More info at https://docs.microsoft.com/en-us/sql/relational-databases/hierarchical-data-sql-server

The easiest way to do that is by binding the array itself as a parameter:

$queryBuilder->andWhere('r.winner IN (:ids)')
             ->setParameter('ids', $ids);

I liked the plugin that Vinny's written and have been using. But in case of tables inside sliding row (tr/td), the rows of nested table are always hidden even after slid up. So I did a quick and simple hack in the plugin not to hide the rows of nested table. Just change the following line

var $cells = $(this).find('td');

to

var $cells = $(this).find('> td');

which finds only immediate tds not nested ones. Hope this helps someone using the plugin and have nested tables.

Short answer: Use the change event. Here's a couple of practical examples. Since I misread the question, I'll include jQuery examples along with plain JavaScript. You're not gaining much, if anything, by using jQuery though.

Single checkbox

Using querySelector.

var checkbox = document.querySelector("input[name=checkbox]");

checkbox.addEventListener('change', function() {
  if (this.checked) {
    console.log("Checkbox is checked..");
  } else {
    console.log("Checkbox is not checked..");
  }
});

<input type="checkbox" name="checkbox" />

Single checkbox with jQuery

$('input[name=checkbox]').change(function() {
  if ($(this).is(':checked')) {
    console.log("Checkbox is checked..")
  } else {
    console.log("Checkbox is not checked..")
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input type="checkbox" name="checkbox" />

Multiple checkboxes

Here's an example of a list of checkboxes. To select multiple elements we use querySelectorAll instead of querySelector. Then use Array.filter and Array.map to extract checked values.

// Select all checkboxes with the name 'settings' using querySelectorAll.
var checkboxes = document.querySelectorAll("input[type=checkbox][name=settings]");
let enabledSettings = []

/*
For IE11 support, replace arrow functions with normal functions and
use a polyfill for Array.forEach:
https://vanillajstoolkit.com/polyfills/arrayforeach/
*/

// Use Array.forEach to add an event listener to each checkbox.
checkboxes.forEach(function(checkbox) {
  checkbox.addEventListener('change', function() {
    enabledSettings = 
      Array.from(checkboxes) // Convert checkboxes to an array to use filter and map.
      .filter(i => i.checked) // Use Array.filter to remove unchecked checkboxes.
      .map(i => i.value) // Use Array.map to extract only the checkbox values from the array of objects.
      
    console.log(enabledSettings)
  })
});

<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Multiple checkboxes with jQuery

let checkboxes = $("input[type=checkbox][name=settings]")
let enabledSettings = [];

// Attach a change event handler to the checkboxes.
checkboxes.change(function() {
  enabledSettings = checkboxes
    .filter(":checked") // Filter out unchecked boxes.
    .map(function() { // Extract values using jQuery map.
      return this.value;
    }) 
    .get() // Get array.
    
  console.log(enabledSettings);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Is there a way to get a list of all the keys in a Go language map?

ks := reflect.ValueOf(m).MapKeys()

how do I iterate over all the keys?

Use the accepted answer:

for k, _ := range m { ... }

A jQuery plugin based on M4N's answer

jQuery.fn.cssNumber = function(prop){
    var v = parseInt(this.css(prop),10);
    return isNaN(v) ? 0 : v;
};

So then you just use this method to get number values

$("#logo").cssNumber("top")

I've posted this comment on a seperate StackOverflow thread, but thought it was worth repeating here:

For our in-house ASP.Net app, adding the "X-UA-Compatible" tag on the web page, in the web.config or in the code-behind made absolutely no difference.

The only thing that worked for us was to manually turn off this setting in IE8:

(Sigh.)

This problem only seems to happen with IE8 & IE9 on intranet sites. External websites will work fine and use the correct version of IE8/9, but for internal websites, IE9 suddenly decides it's actually IE7, and doesn't have any HTML 5 support.

No, I don't quite understand this logic either.

My reluctant solution has been to test whether the browser has HTML 5 support (by creating a canvas, and testing if it's valid), and displaying this message to the user if it's not valid:

It's not particularly user-friendly, but getting the user to turn off this annoying setting seems to be the only way to let them run in-house HTML 5 web apps properly.

Or get the users to use Chrome. ;-)
