The most common reason could be the database connection string. You have to change the connection string attachDBFile=|DataDirectory|file_name.mdf. there might be problem in host name which would be (local),localhost or .\sqlexpress.

Once you have a paid account on GitHub, it is not obvious how to create a private repository. To create a private repository for an organization with paid account, go to https://github.com/organizations/MYORGANIZATIONNAME.

The only way I've figured how to navigate there is:

• Go to to your organization's home page: https://github.com/MYORGANIZATIONNAME
• Click on the "Edit MYORGANIZATION's Profile" button at the top right
• Click on the "GitHub" icon at the top left (non-obvious)
• Click on the "News Feed" tab (non-obvious)
• Click on the "New Repository" button at the right ...

If you are using this form of the branch command (with start point), it does not matter where your HEAD is.

What you are doing:

git checkout dev
git branch test 07aeec983bfc17c25f0b0a7c1d47da8e35df7af8

• First, you set your HEAD to the branch dev,

• Second, you start a new branch on commit 07aeec98. There is no bb.txt at this commit (according to your github repo).

If you want to start a new branch at the location you have just checked out, you can either run branch with no start point:

git branch test

or as other have answered, branch and checkout there in one operation:

git checkout -b test

I think that you might be confused by that fact that 07aeec98 is part of the branch dev. It is true that this commit is an ancestor of dev, its changes are needed to reach the latest commit in dev. However, they are other commits that are needed to reach the latest dev, and these are not necessarily in the history of 07aeec98.

8480e8ae (where you added bb.txt) is for example not in the history of 07aeec98. If you branch from 07aeec98, you won't get the changes introduced by 8480e8ae.

In other words: if you merge branch A and branch B into branch C, then create a new branch on a commit of A, you won't get the changes introduced in B.

Same here, you had two parallel branches master and dev, which you merged in dev. Branching out from a commit of master (older than the merge) won't provide you with the changes of dev.

If you want to permanently integrate new changes from master into your feature branches, you should merge master into them and go on. This will create merge commits in your feature branches, though.

If you have not published your feature branches, you can also rebase them on the updated master: git rebase master featureA. Be prepared to solve possible conflicts.

If you want a workflow where you can work on feature branches free of merge commits and still integrate with newer changes in master, I recommend the following:

• base every new feature branch on a commit of master
• create a dev branch on a commit of master
• when you need to see how your feature branch integrates with new changes in master, merge both master and the feature branch into dev.

Do not commit into dev directly, use it only for merging other branches.

For example, if you are working on feature A and B:

a---b---c---d---e---f---g -master
    \       \
     \       \-x -featureB
      \
       \-j---k -featureA

Merge branches into a dev branch to check if they work well with the new master:

a---b---c---d---e---f---g -master
    \       \            \
     \       \            \--x'---k' -dev
      \       \             /    /   
       \       \-x----------    /    -featureB
        \                      /
         \-j---k--------------- -featureA

You can continue working on your feature branches, and keep merging in new changes from both master and feature branches into dev regularly.

a---b---c---d---e---f---g---h---i----- -master
    \       \            \            \
     \       \            \--x'---k'---i'---l' -dev
      \       \             /    /         /
       \       \-x----------    /         /  -featureB
        \                      /         /  
         \-j---k-----------------l------ -featureA

When it is time to integrate the new features, merge the feature branches (not dev!) into master.

Array's has

array.length

whereas List has

list.size()

Replace array.size() to array.length

I think there is only one intuitive solution and it is:

int[] someArray = {1,2,3,4,5};
int first = someArray[0];
int last = someArray[someArray.length - 1];
System.out.println("First: " + first + "\n" + "Last: " + last);

Output:

First: 1
Last: 5

After Commenting

          // [DataType(DataType.DateTime)] 

Use the Data Annotation Attribute:

[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]

STEP-7 of the following link may help you...

http://ilyasmamunbd.blogspot.com/2014/12/jquery-datepicker-in-aspnet-mvc-5.html

You should re-assign the result of the replacement, like this:

 sentence = sentence.replace("and", " ");

Be aware that the String class is immutable, meaning that all of its methods return a new string and never modify the original string in-place, so the result of invoking a method in an instance of String must be assigned to a variable or used immediately for the change to take effect.

I was checking how ax.axvline does work, and I've written a small function that resembles part of its idea:

import matplotlib.pyplot as plt
import matplotlib.lines as mlines

def newline(p1, p2):
    ax = plt.gca()
    xmin, xmax = ax.get_xbound()

    if(p2[0] == p1[0]):
        xmin = xmax = p1[0]
        ymin, ymax = ax.get_ybound()
    else:
        ymax = p1[1]+(p2[1]-p1[1])/(p2[0]-p1[0])*(xmax-p1[0])
        ymin = p1[1]+(p2[1]-p1[1])/(p2[0]-p1[0])*(xmin-p1[0])

    l = mlines.Line2D([xmin,xmax], [ymin,ymax])
    ax.add_line(l)
    return l

So, if you run the following code you will realize how does it work. The line will span the full range of your plot (independently on how big it is), and the creation of the line doesn't rely on any data point within the axis, but only in two fixed points that you need to specify.

import numpy as np
x = np.linspace(0,10)
y = x**2

p1 = [1,20]
p2 = [6,70]

plt.plot(x, y)
newline(p1,p2)
plt.show()

You can use jquery load for that.

<script type="text/javascript">
$(document).ready(function(e) {
    $('#header').load('name.html',function(){alert('loaded')});
});
</script>

Don't forget to include jquery library befor above code.

we have two way to concatenate columns in MySql

select concat(hobbies) as `Hobbies` from people_hobbies where 1

Or

select group_concat(hobbies) as `Hobbies` from people_hobbies where 1

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+

Another way to work out here is to use java.sql.Date as sql Date doesn't have time associated with it, whereas java.util.Date always have a timestamp. Whats catching point here is java.sql.Date extends java.util.Date, therefore java.util.Date variable can be a reference to java.sql.Date(without time) and to java.util.Date of course(with timestamp).

Use try_files and named location block ('@apachesite'). This will remove unnecessary regex match and if block. More efficient.

location / {
    root /path/to/root/of/static/files;
    try_files $uri $uri/ @apachesite;

    expires max;
    access_log off;
}

location @apachesite {
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
}

Update: The assumption of this config is that there doesn't exist any php script under /path/to/root/of/static/files. This is common in most modern php frameworks. In case your legacy php projects have both php scripts and static files mixed in the same folder, you may have to whitelist all of the file types you want nginx to serve.

Sometimes the .gz extension is wrongfully appended to the filename.

• Run file foo.csv.gz to know the actual file type.
• Rename the file to foo.csv or whatever the actual file type is.

This is not an answer but a feedback with few compilers of 2021. On Intel CoffeeLake 9900k.

With Microsoft compiler (VS2019), toolset v142:

unsigned        209695540000    1.8322 sec      28.6152 GB/s
uint64_t        209695540000    3.08764 sec     16.9802 GB/s

With Intel compiler 2021:

unsigned        209695540000    1.70845 sec     30.688 GB/s
uint64_t        209695540000    1.57956 sec     33.1921 GB/s

According to Mysticial's answer, Intel compiler is aware of False Data Dependency, but not Microsoft compiler.

For intel compiler, I used /QxHost (optimize of CPU's architecture which is that of the host) /Oi (enable intrinsic functions) and #include <nmmintrin.h> instead of #include <immintrin.h>.

Full compile command: /GS /W3 /QxHost /Gy /Zi /O2 /D "NDEBUG" /D "_CONSOLE" /D "_UNICODE" /D "UNICODE" /Qipo /Zc:forScope /Oi /MD /Fa"x64\Release\" /EHsc /nologo /Fo"x64\Release\" //fprofile-instr-use "x64\Release\" /Fp"x64\Release\Benchmark.pch" .

Coffee lake specification update "POPCNT instruction may take longer to execute than expected".

Do not use Class.newInstance(); see this thread: Why is Class.newInstance() evil?

Like other answers say, use Constructor.newInstance() instead.

If you get the context via the parameter list of Configure in Startup.cs, You can instead do this:

public void Configure(IApplicationBuilder app, IHostingEnvironment env,  LoggerFactory loggerFactory,
    ApplicationDbContext context)
 {
      context.Database.Migrate();
      ...

Of course you can, in the sense that your RDBMS will let you do it. The answer to a question of whether or not you should do it is different, though: in most situations, values that have a meaning outside your database system should not be chosen to be a primary key.

If you know that the value is unique in the system that you are modeling, it is appropriate to add a unique index or a unique constraint to your table. However, your primary key should generally be some "meaningless" value, such as an auto-incremented number or a GUID.

The rationale for this is simple: data entry errors and infrequent changes to things that appear non-changeable do happen. They become much harder to fix on values which are used as primary keys.

This error can happen because some MFC library (eg. mfc120.dll) from which the DLL is dependent is missing in windows/system32 folder.

Every time you are creating plots you might get this error - "Error in plot.new() : figure margins too large". To avoid such errors you can first check par("mar") output. You should be getting:

[1] 5.1 4.1 4.1 2.1

To change that write:

par(mar=c(1,1,1,1))

This should rectify the error. Or else you can change the values accordingly.

Hope this works for you.

I agree with Jim Blizard. The database is not the part of your technology stack that should send emails. For example, what if you send an email but then roll back the change that triggered that email? You can't take the email back.

It's better to send the email in your application code layer, after your app has confirmed that the SQL change was made successfully and committed.

Best solution I've found:

AppendToHead('script', 'alert("hii"); ');
//or
AppendToHead('script', 'http://example.com/script.js');
//or
AppendToHead('style',  '#myDiv{color:red;} ');
//or
AppendToHead('style',  'http://example.com/style.css');



function AppendToHead(elemntType, content){
    // detect whether provided content is "link" (instead of inline codes)
    var Is_Link = content.split(/\r\n|\r|\n/).length <= 1  &&  content.indexOf("//") > -1 && content.indexOf(" ")<=-1;
    if(Is_Link){
        if (elemntType=='script')    { var x=document.createElement('script');x.id=id;  x.src=content;  x.type='text/javascript'; }
        else if (elemntType=='style'){ var x=document.createElement('link');  x.id=id;  x.href=content; x.type='text/css';  x.rel = 'stylesheet'; }
    }
    else{
        var x = document.createElement(elemntType);
        if (elemntType=='script')    { x.type='text/javascript';    x.innerHTML = content;  }
        else if (elemntType=='style'){ x.type='text/css';    if (x.styleSheet){ x.styleSheet.cssText=content; } else { x.appendChild(document.createTextNode(content)); }   }
    }
    //append in head
    (document.head || document.getElementsByTagName('head')[0]).appendChild(x);
}

Adding external Jar is not smart in case you want to change the project location in filesystem.

The best way is to add the jar to build path so your project will compile if exported:

1. Create a folder called lib in your project folder.

2. copy to this folder all the jar files you need.

3. Refresh your project in eclipse.

4. Select all the jar files, then right click on one of them and select Build Path -> Add to Build Path

Your concatenation syntax is correct.

Most likely the callback function isn't even being called. You can test that by putting an alert(), console.log() or debugger line in that function.

If it isn't being called, most likely there's an AJAX error. Look at chaining a .fail() handler after $.post() to find out what the error is, e.g.:

$.post('ajaxskeleton.php', {
    red: text       
}, function(){
    $('#part' + number).html(text);
}).fail(function(jqXHR, textStatus, errorThrown) {
    console.log(arguments);
});

Using PHP i've found a quite simple way to do this. Guys, Just Use something like this

<input list="customers" name="customer_id" required class="form-control" placeholder="Customer Name">
            <datalist id="customers">
                <?php 
    $querySnamex = "SELECT * FROM `customer` WHERE fname!='' AND lname!='' order by customer_id ASC";
    $resultSnamex = mysqli_query($con,$querySnamex) or die(mysql_error());

                while ($row_this = mysqli_fetch_array($resultSnamex)) {
                    echo '<option data-value="'.$row_this['customer_id'].'">'.$row_this['fname'].' '.$row_this['lname'].'</option>
                    <input type="hidden" name="customer_id_real" value="'.$row_this['customer_id'].'" id="answerInput-hidden">';
                }

                 ?>
            </datalist>

The Code Above lets the form carry the id of the option also selected.

The following is the complete example containing both XML and XSLT where substring-before and substring-after are used

<?xml version="1.0" encoding="UTF-8"?>
<persons name="Group_SOEM">
    <person>
        <first>Joe Smith</first>
        <last>Joe Smith</last>
        <address>123 Main St, Anycity</address>
    </person>
</persons>    

The following is XSLT which changes value of first/last name by separating the value by space so that after applying this XSL the first name element will have value "Joe" and last "Smith".

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="first">
    <first>
        <xsl:value-of select="substring-before(.,' ')" />
    </first>
</xsl:template> 
<xsl:template match="last">
    <last>
        <xsl:value-of select="substring-after(.,' ')" />
    </last>
</xsl:template> 
<xsl:template match="@* | node()">
    <xsl:copy>
        <xsl:apply-templates select="@* | node()" />
    </xsl:copy>
</xsl:template>
</xsl:stylesheet>   

No, there is not; see §3.2.4 "Compound Commands" in the Bash Reference Manual for information about the control structures that do exist. In particular, note the mention of break and continue, which aren't as flexible as goto, but are more flexible in Bash than in some languages, and may help you achieve what you want. (Whatever it is that you want . . .)

I believe you are all wrong. you need to do:

array = array[] in order to define it, and then:

array.append ["hello"] to add to it.

Try to

source ~/anaconda3/bin/activate root
anaconda-navigator

https://github.com/ContinuumIO/anaconda-issues/issues/1580

In short, if you have multiple routes defined for your app's routing, enclosed with Switch component like this;

<Switch>

  <Route exact path="/" component={Home} />
  <Route path="/detail" component={Detail} />

  <Route exact path="/functions" component={Functions} />
  <Route path="/functions/:functionName" component={FunctionDetails} />

</Switch>

Then you have to put exact keyword to the Route which it's path is also included by another Route's path. For example home path / is included in all paths so it needs to have exact keyword to differentiate it from other paths which start with /. The reason is also similar to /functions path. If you want to use another route path like /functions-detail or /functions/open-door which includes /functions in it then you need to use exact for the /functions route.

If you don't wish to mess with IFS (perhaps for the code within the loop) this might help.

If know that your string will not have whitespace, you can substitute the ';' with a space and use the for/in construct:

#local str
for str in ${STR//;/ } ; do 
   echo "+ \"$str\""
done

But if you might have whitespace, then for this approach you will need to use a temp variable to hold the "rest" like this:

#local str rest
rest=$STR
while [ -n "$rest" ] ; do
   str=${rest%%;*}  # Everything up to the first ';'
   # Trim up to the first ';' -- and handle final case, too.
   [ "$rest" = "${rest/;/}" ] && rest= || rest=${rest#*;}
   echo "+ \"$str\""
done

SELECT * FROM table SAMPLE(10) WHERE ROWNUM <= 20;

This is more efficient as it doesn't need to sort the Table.

You have to define the compare first. There are 3 ways to do that:

1. use class
2. use struct (which is same as class)
3. use lambda function.

It's easy to use class/struct because easy to declare just write this line of code above your executing code

struct compare{
  public:
  bool operator()(Node& a,Node& b) // overloading both operators 
  {
      return a.w < b.w: // if you want increasing order;(i.e increasing for minPQ)
      return a.w > b.w // if you want reverse of default order;(i.e decreasing for minPQ)
   }
};

Calling code:

priority_queue<Node,vector<Node>,compare> pq;

Most commands allow args to come in any order. Just move the commented flags to the end of the line:

ls -l -a /etc # -F is turned off

Then to turn it back on, just uncomment and remove the text:

ls -l -a /etc -F

From javadoc:

Unlike commit(), which writes its preferences out to persistent storage synchronously, apply() commits its changes to the in-memory SharedPreferences immediately but starts an asynchronous commit to disk and you won't be notified of any failures. If another editor on this SharedPreferences does a regular commit() while a > apply() is still outstanding, the commit() will block until all async commits are completed as well as the commit itself

I had the same problem. This doesn't work:

npm uninstall -g angular/cli
npm cache clean

instead use:

npm uninstall -g @ angular/cli

For me the shortest way to get locale date and in correct format for input type="date" is this :

var d = new Date(); 
var today = d.getFullYear()+"-"+("0"+(d.getMonth()+1)).slice(-2)+"-"+("0"+d.getDate()).slice(-2);

Or this :

var d = new Date().toLocaleDateString().split('/');
var today = d[2]+"-"+("0"+d[0]).slice(-2)+"-"+("0"+d[1]).slice(-2);

Then just set the date input value :

$('#datePicker').val(today);

Option 1 is the only good solution.

Why?

• Option 2 does the same but you repeat the column name lots of times; additionally the SQL engine doesn't immediately know that you want to check if the value is one of the values in a fixed list. However, a good SQL engine could optimize it to have equal performance like with IN. There's still the readability issue though...

• Option 3 is simply horrible performance-wise. It sends a query every loop and hammers the database with small queries. It also prevents it from using any optimizations for "value is one of those in a given list"

This will be used to change the Html content inside the span

 $('#abc span').html('goes inside the span');

if you want to change the text inside the span, you can use:

 $('#abc span').text('goes inside the span');

This flexbox principle also works horizontally

During calculations of flex bases and flexible lengths, auto margins are treated as 0.
Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Setting an automatic left margin for the Last Item will do the work.

.last-item {
  margin-left: auto;
}

Code Example:

.container {_x000D_
  display: flex;_x000D_
  width: 400px;_x000D_
  outline: 1px solid black;_x000D_
}_x000D_
_x000D_
p {_x000D_
  height: 50px;_x000D_
  width: 50px;_x000D_
  margin: 5px;_x000D_
  background-color: blue;_x000D_
}_x000D_
_x000D_
.last-item {_x000D_
  margin-left: auto;_x000D_
}

<div class="container">_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p class="last-item"></p>_x000D_
</div>

kennytm's links are dead and he doesn't provide an example so here's how you do substrings:

=MID(text, start_num, char_num)

Let's say cell A1 is Hello.

=MID(A1, 2, 3) 

Would return

ell

Because it says to start at character 2, e, and to return 3 characters.

Here is a complete example. It tries to get the country code from TelephonyManager (from SIM or CDMA devices), and if not available, tries to get it from the local configuration.

            countryCode = getCDMACountryIso();
        }
        else {
            // For 3G devices (with SIM) query getNetworkCountryIso()
            countryCode = tm.getNetworkCountryIso();
        }

        if (countryCode != null && countryCode.length() == 2)
            return countryCode.toLowerCase();
    }

    // If network country not available (tablets maybe), get country code from Locale class
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        countryCode = context.getResources().getConfiguration().getLocales().get(0).getCountry();
    }

        countryCode = context.getResources().getConfiguration().locale.getCountry();
    }

    if (countryCode != null && countryCode.length() == 2)

Also another idea is to try an API request like in this answer.

std::stringstream::str() is the method you are looking for.

With std::stringstream:

template <class T>
std::string YourClass::NumericToString(const T & NumericValue)
{
    std::stringstream ss;
    ss << NumericValue;
    return ss.str();
}

std::stringstream is a more generic tool. You can use the more specialized class std::ostringstream for this specific job.

template <class T>
std::string YourClass::NumericToString(const T & NumericValue)
{
    std::ostringstream oss;
    oss << NumericValue;
    return oss.str();
}

If you are working with std::wstring type of strings, you must prefer std::wstringstream or std::wostringstream instead.

template <class T>
std::wstring YourClass::NumericToString(const T & NumericValue)
{
    std::wostringstream woss;
    woss << NumericValue;
    return woss.str();
}

if you want the character type of your string could be run-time selectable, you should also make it a template variable.

template <class CharType, class NumType>
std::basic_string<CharType> YourClass::NumericToString(const NumType & NumericValue)
{
    std::basic_ostringstream<CharType> oss;
    oss << NumericValue;
    return oss.str();
}

For all the methods above, you must include the following two header files.

#include <string>
#include <sstream>

Note that, the argument NumericValue in the examples above can also be passed as std::string or std::wstring to be used with the std::ostringstream and std::wostringstream instances respectively. It is not necessary for the NumericValue to be a numeric value.

The code below will convert any XMLObject or string to a native JavaScript object. Then you can walk on the object to extract any value you want.

/**

 * 
 * @param {XMLDomElement|String} source The XML string or the XMLDomElement prefreably which containts the necessary data for the object.
 * @param {Boolean} [includeRoot] Whether the "required" main container node should be a part of the resultant object or not.
 * @return {Object} The native JavaScript object which is contructed from the given XML data or false if any error occured.

            }
        }
        source = source.nextSibling;

A message has a header part and a message body separated by a blank line. The blank line is ALWAYS needed even if there is no message body. The header starts with a command and has additional lines of key value pairs separated by a colon and a space. If there is a message body, it can be anything you want it to be.

Lines in the header and the blank line at the end of the header must end with a carraige return and linefeed pair (see HTTP header line break style) so that's why those lines have \r\n at the end.

A URL has the form of http://host:port/path?query_string

There are two main ways of submitting a request to a website:

• GET: The query string is optional but, if specified, must be reasonably short. Because of this the header could just be the GET command and nothing else. A sample message could be:

  GET /path?query_string HTTP/1.0\r\n
  \r\n
  

• POST: What would normally be in the query string is in the body of the message instead. Because of this the header needs to include the Content-Type: and Content-Length: attributes as well as the POST command. A sample message could be:

  POST /path HTTP/1.0\r\n
  Content-Type: text/plain\r\n
  Content-Length: 12\r\n
  \r\n
  query_string
  

So, to answer your question: if the URL you are interested in POSTing to is http://api.somesite.com/apikey=ARG1&command=ARG2 then there is no body or query string and, consequently, no reason to POST because there is nothing to put in the body of the message and so nothing to put in the Content-Type: and Content-Length:

I guess you could POST if you really wanted to. In that case your message would look like:

POST /apikey=ARG1&command=ARG2 HTTP/1.0\r\n
\r\n

So to send the message the C program needs to:

• create a socket
• lookup the IP address
• open the socket
• send the request
• wait for the response
• close the socket

The send and receive calls won't necessarily send/receive ALL the data you give them - they will return the number of bytes actually sent/received. It is up to you to call them in a loop and send/receive the remainder of the message.

What I did not do in this sample is any sort of real error checking - when something fails I just exit the program. Let me know if it works for you:

#include <stdio.h> /* printf, sprintf */
#include <stdlib.h> /* exit */
#include <unistd.h> /* read, write, close */
#include <string.h> /* memcpy, memset */
#include <sys/socket.h> /* socket, connect */
#include <netinet/in.h> /* struct sockaddr_in, struct sockaddr */
#include <netdb.h> /* struct hostent, gethostbyname */

void error(const char *msg) { perror(msg); exit(0); }

int main(int argc,char *argv[])
{
    /* first what are we going to send and where are we going to send it? */
    int portno =        80;
    char *host =        "api.somesite.com";
    char *message_fmt = "POST /apikey=%s&command=%s HTTP/1.0\r\n\r\n";

    struct hostent *server;
    struct sockaddr_in serv_addr;
    int sockfd, bytes, sent, received, total;
    char message[1024],response[4096];

    if (argc < 3) { puts("Parameters: <apikey> <command>"); exit(0); }

    /* fill in the parameters */
    sprintf(message,message_fmt,argv[1],argv[2]);
    printf("Request:\n%s\n",message);

    /* create the socket */
    sockfd = socket(AF_INET, SOCK_STREAM, 0);
    if (sockfd < 0) error("ERROR opening socket");

    /* lookup the ip address */
    server = gethostbyname(host);
    if (server == NULL) error("ERROR, no such host");

    /* fill in the structure */
    memset(&serv_addr,0,sizeof(serv_addr));
    serv_addr.sin_family = AF_INET;
    serv_addr.sin_port = htons(portno);
    memcpy(&serv_addr.sin_addr.s_addr,server->h_addr,server->h_length);

    /* connect the socket */
    if (connect(sockfd,(struct sockaddr *)&serv_addr,sizeof(serv_addr)) < 0)
        error("ERROR connecting");

    /* send the request */
    total = strlen(message);
    sent = 0;
    do {
        bytes = write(sockfd,message+sent,total-sent);
        if (bytes < 0)
            error("ERROR writing message to socket");
        if (bytes == 0)
            break;
        sent+=bytes;
    } while (sent < total);

    /* receive the response */
    memset(response,0,sizeof(response));
    total = sizeof(response)-1;
    received = 0;
    do {
        bytes = read(sockfd,response+received,total-received);
        if (bytes < 0)
            error("ERROR reading response from socket");
        if (bytes == 0)
            break;
        received+=bytes;
    } while (received < total);

    if (received == total)
        error("ERROR storing complete response from socket");

    /* close the socket */
    close(sockfd);

    /* process response */
    printf("Response:\n%s\n",response);

    return 0;
}

Like the other answer pointed out, 4096 bytes is not a very big response. I picked that number at random assuming that the response to your request would be short. If it can be big you have two choices:

• read the Content-Length: header from the response and then dynamically allocate enough memory to hold the whole response.
• write the response to a file as the pieces arrive

Additional information to answer the question asked in the comments:

What if you want to POST data in the body of the message? Then you do need to include the Content-Type: and Content-Length: headers. The Content-Length: is the actual length of everything after the blank line that separates the header from the body.

Here is a sample that takes the following command line arguments:

• host
• port
• command (GET or POST)
• path (not including the query data)
• query data (put into the query string for GET and into the body for POST)
• list of headers (Content-Length: is automatic if using POST)

So, for the original question you would run:

a.out api.somesite.com 80 GET "/apikey=ARG1&command=ARG2"

And for the question asked in the comments you would run:

a.out api.somesite.com 80 POST / "name=ARG1&value=ARG2" "Content-Type: application/x-www-form-urlencoded"

Here is the code:

#include <stdio.h> /* printf, sprintf */
#include <stdlib.h> /* exit, atoi, malloc, free */
#include <unistd.h> /* read, write, close */
#include <string.h> /* memcpy, memset */

#include <netdb.h> /* struct hostent, gethostbyname */

You can (should) use CROSS JOIN. Following query will be equivalent to yours:

SELECT 
   table1.columnA
 , table2.columnA
FROM table1 
CROSS JOIN table2
WHERE table1.columnA = 'Some value'

or you can even use INNER JOIN with some always true conditon:

FROM table1 
INNER JOIN table2 ON 1=1

Robocopy is designed for reliable copying with many copy options, file selection restart, etc.

/xf to excludes files and /e for subdirectories:

robocopy $copyAdmin $AdminPath /e /xf "web.config" "Deploy"

Procedure for global setting of client/server logging of SOAP/REST requests/ responses with log4j logger. This way you set up logging for the whole application without having to change the code, war, jar files, etc.

1. install file cxf-rt-features-logging-X.Y.Z.jar to your CLASS_PATH

2. create file (path for example: /opt/cxf/cxf-logging.xml):

   <?xml version="1.0" encoding="UTF-8"?>
   <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://cxf.apache.org/core" xsi:schemaLocation="http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
   <cxf:bus>
    <cxf:features>
    <bean class="org.apache.cxf.ext.logging.LoggingFeature">
    <property name="prettyLogging" value="true"/>
    </bean>
    </cxf:features>
    </cxf:bus>
    </beans>
   

3. set logging for org.apache.cxf (log4j 1.x) log4j.logger.org.apache.cxf=INFO,YOUR_APPENDER

4. set these properties on java start-up

java ... -Dcxf.config.file.url=file:///opt/cxf/cxf-logging.xml -Dorg.apache.cxf.Logger=org.apache.cxf.common.logging.Log4jLogger -Dcom.sun.xml.ws.transport.http.client.HttpTransportPipe.dump=true -Dcom.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.dump=true -Dcom.sun.xml.ws.transport.http.HttpAdapter.dump=true -Dcom.sun.xml.internal.ws.transport.http.HttpAdapter.dump=true ...

I don't know why, but it is necessary to set variables as well com.sun.xml.*

I have Had the same issue and the only Solution i found was open Package manager> Select Microsoft and .Net as Package Source and You will install it..

Resize image with high quality:

private static InputStream resizeImage(InputStream uploadedInputStream, String fileName, int width, int height) {

        try {
            BufferedImage image = ImageIO.read(uploadedInputStream);
            Image originalImage= image.getScaledInstance(width, height, Image.SCALE_DEFAULT);

            int type = ((image.getType() == 0) ? BufferedImage.TYPE_INT_ARGB : image.getType());
            BufferedImage resizedImage = new BufferedImage(width, height, type);

            Graphics2D g2d = resizedImage.createGraphics();
            g2d.drawImage(originalImage, 0, 0, width, height, null);
            g2d.dispose();
            g2d.setComposite(AlphaComposite.Src);
            g2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION,RenderingHints.VALUE_INTERPOLATION_BILINEAR);
            g2d.setRenderingHint(RenderingHints.KEY_RENDERING,RenderingHints.VALUE_RENDER_QUALITY);
            g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);

            ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

            ImageIO.write(resizedImage, fileName.split("\\.")[1], byteArrayOutputStream);
            return new ByteArrayInputStream(byteArrayOutputStream.toByteArray());
        } catch (IOException e) {
            // Something is going wrong while resizing image
            return uploadedInputStream;
        }
    }

According to Dangerously Set innerHTML,

Improper use of the innerHTML can open you up to a cross-site scripting (XSS) attack. Sanitizing user input for display is notoriously error-prone, and failure to properly sanitize is one of the leading causes of web vulnerabilities on the internet.

Our design philosophy is that it should be "easy" to make things safe, and developers should explicitly state their intent when performing “unsafe” operations. The prop name dangerouslySetInnerHTML is intentionally chosen to be frightening, and the prop value (an object instead of a string) can be used to indicate sanitized data.

After fully understanding the security ramifications and properly sanitizing the data, create a new object containing only the key __html and your sanitized data as the value. Here is an example using the JSX syntax:

function createMarkup() {
    return {
       __html: 'First · Second'    };
 }; 

<div dangerouslySetInnerHTML={createMarkup()} /> 

Read more about it using below link:

documentation: React DOM Elements - dangerouslySetInnerHTML.

protected void gvTurnos_RowDataBound(object sender, GridViewRowEventArgs e)
{
    try
    {

        if (e.Row.RowType == DataControlRowType.EmptyDataRow)
        {
            LinkButton btn = (LinkButton)e.Row.FindControl("btnAgregarVacio");
            if (btn != null)
            {
                btn.Visible = rbFiltroEstatusCampus.SelectedValue == "1" ? true : false;
            }
        }
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

Your code looks fine except the possibility that if the variable declaration is inside a dom read handler then it will not be a global variable... it will be a closure variable

jQuery(function(){
    //here it is a closure variable
    var a_href;
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

To make the variable global, one solution is to declare the variable in global scope

var a_href;
jQuery(function(){
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

another is to set the variable as a property of the window object

window.a_href = $(this).attr('href')

Why console printing undefined

You are getting the output as undefined because even though the variable is declared, you have not initialized it with a value, the value of the variable is set only after the a element is clicked till that time the variable will have the value undefined. If you are not declaring the variable it will throw a ReferenceError

you can try to use cv2 like this

import cv2

image= cv2.imread('image page')

cv2.imshow('image', image)

cv2.waitKey(0)

cv2.destroyAllWindows()

It is very simple:

1. To check the current status of any file in the current dir, whether it is staged or not:

   git status

2. Staging any files:

   git add . for all files in the current directory

   git add <filename> for specific file

3. Unstaging the file:

   git restore --staged <filename>

One caveat, though. Note that np.array(None).size returns 1! This is because a.size is equivalent to np.prod(a.shape), np.array(None).shape is (), and an empty product is 1.

>>> import numpy as np
>>> np.array(None).size
1
>>> np.array(None).shape
()
>>> np.prod(())
1.0

Therefore, I use the following to test if a numpy array has elements:

>>> def elements(array):
    ...     return array.ndim and array.size

>>> elements(np.array(None))
0
>>> elements(np.array([]))
0
>>> elements(np.zeros((2,3,4)))
24

Here are the high-level differences:

Forking

Pros

• Keeps branches separated by user
• Reduces clutter in the primary repository
• Your team process reflects the external contributor process

Cons

• Makes it more difficult to see all of the branches that are active (or inactive, for that matter)
• Collaborating on a branch is trickier (the fork owner needs to add the person as a collaborator)
• You need to understand the concept of multiple remotes in Git
  • Requires additional mental bookkeeping
  • This will make the workflow more difficult for people who aren't super comfortable with Git

Branching

Pros

• Keeps all of the work being done around a project in one place
• All collaborators can push to the same branch to collaborate on it
• There's only one Git remote to deal with

Cons

• Branches that get abandoned can pile up more easily
• Your team contribution process doesn't match the external contributor process
• You need to add team members as contributors before they can branch

Use pure js

async function saveFile() _x000D_
{_x000D_
    let formData = new FormData();           _x000D_
    formData.append("file", sortpicture.files[0]);_x000D_
    await fetch('/uploads', {method: "POST", body: formData});    _x000D_
    alert('works');_x000D_
}

<input id="sortpicture" type="file" name="sortpic" />_x000D_
<button id="upload" onclick="saveFile()">Upload</button>_x000D_
<br>Before click upload look on chrome>console>network (in this snipped we will see 404)

The filename is automatically included to request and server can read it, the 'content-type' is automatically set to 'multipart/form-data'. Here is more developed example with error handling and additional json sending

async function saveFile(inp) _x000D_
{_x000D_
    let user = { name:'john', age:34 };_x000D_
    let formData = new FormData();_x000D_
    let photo = inp.files[0];      _x000D_
         _x000D_
    formData.append("photo", photo);_x000D_
    formData.append("user", JSON.stringify(user));  _x000D_
    _x000D_
    try {_x000D_
       let r = await fetch('/upload/image', {method: "POST", body: formData}); _x000D_
       console.log('HTTP response code:',r.status); _x000D_
       alert('success');_x000D_
    } catch(e) {_x000D_
       console.log('Huston we have problem...:', e);_x000D_
    }_x000D_
    _x000D_
}

<input type="file" onchange="saveFile(this)" >_x000D_
<br><br>_x000D_
Before selecting the file Open chrome console > network tab to see the request details._x000D_
<br><br>_x000D_
<small>Because in this example we send request to https://stacksnippets.net/upload/image the response code will be 404 ofcourse...</small>

I often use this pattern and recommend you to use it as well:

class MyMap : public std::map<int, int>
{
public:
    MyMap()
    {
        //either
        insert(make_pair(1, 2));
        insert(make_pair(3, 4));
        insert(make_pair(5, 6));
        //or
        (*this)[1] = 2;
        (*this)[3] = 4;
        (*this)[5] = 6;
    }
} const static my_map;

Sure it is not very readable, but without other libs it is best we can do. Also there won't be any redundant operations like copying from one map to another like in your attempt.

This is even more useful inside of functions: Instead of:

void foo()
{
   static bool initComplete = false;
   static Map map;
   if (!initComplete)
   {
      initComplete = true;
      map= ...;
   }
}

Use the following:

void bar()
{
    struct MyMap : Map
    {
      MyMap()
      {
         ...
      }
    } static mymap;
}

Not only you don't need here to deal with boolean variable anymore, you won't have hidden global variable that is checked if initializer of static variable inside function was already called.

I personally don't like atoi function. I would suggest sscanf:

char myarray[5] = {'-', '1', '2', '3', '\0'};
int i;
sscanf(myarray, "%d", &i);

It's very standard, it's in the stdio.h library :)

And in my opinion, it allows you much more freedom than atoi, arbitrary formatting of your number-string, and probably also allows for non-number characters at the end.

EDIT I just found this wonderful question here on the site that explains and compares 3 different ways to do it - atoi, sscanf and strtol. Also, there is a nice more-detailed insight into sscanf (actually, the whole family of *scanf functions).

EDIT2 Looks like it's not just me personally disliking the atoi function. Here's a link to an answer explaining that the atoi function is deprecated and should not be used in newer code.

Try something like this to convert JToken to JArray:

static public JArray convertToJArray(JToken obj)
{
    // if ((obj).Type == JTokenType.Null) --> You can check if it's null here

    if ((obj).Type == JTokenType.Array)
        return (JArray)(obj);
    else
        return new JArray(); // this will return an empty JArray
}

When you use the start command to a website it will use the default browser by default but if you want to use a specific browser then use start iexplorer.exe www.website.com

Also you cannot have http:// in the url.

I find this code and is resolve my problem.

http://arcware.net/setting-http-header-authorization-for-web-services/

protected override WebRequest GetWebRequest(Uri uri)
{
    // Assuming authValue is set from somewhere, such as the config file
    HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(uri);
    request.Headers.Add("Authorization", string.Format("Basic {0}", authValue));
    return request;
}

SimpleDateFormat.format(...) takes a Date as parameter and format Date to String. So you need have a look API carefully

It cant find the entry point for your program, in this case main(). Your linker settings are likely incorrect.

See this post here

In actionPerformed(ActionEvent e) you call encrypt(), which is declared to throw Exception. However, actionPerformed neither catches this Exception (with try/catch around the call to encrypt()) nor declares that it throws Exception itself.

Your encrypt method, however, does not truly throw Exception. It swallows all Exceptions without even as much as logging a complaint. (Bad practice and bad style!)

Also, your encrypt method does the following:

public static byte[] encrypt(String toEncrypt) throws Exception {
  try{
    ....
    return encrypted; // HERE YOU CORRECTLY RETURN A VALUE
  } catch(Exception e) {
  }
  // YOU DO NOT RETURN ANYTHING HERE
}

That is, if you do catch any Exception, you discard it silently and then fall off the bottom of your encrypt method without actually returning anything. This won't compile (as you see), because a method that is declared to return a value must either return a value or throw an Exception for every single possible code path.

Plain JavaScript is the best pick for small onetimers.

On the other hand, if you need more date stuff, MomentJS is a great solution.

For example:

moment().format('YYYY-MM-DD HH:m:s');     // now() -> 2015-03-24 14:32:20
moment("20111031", "YYYYMMDD").fromNow(); // 3 years ago
moment("20120620", "YYYYMMDD").fromNow(); // 3 years ago
moment().startOf('day').fromNow();        // 11 hours ago
moment().endOf('day').fromNow();          // in 13 hours

There is no method for dropping a collection from mongoose, the best you can do is remove the content of one :

Model.remove({}, function(err) { 
   console.log('collection removed') 
});

But there is a way to access the mongodb native javascript driver, which can be used for this

mongoose.connection.collections['collectionName'].drop( function(err) {
    console.log('collection dropped');
});

Warning

Make a backup before trying this in case anything goes wrong!

Given your URL:

http://locahost:8000/example?a=10

The best way that I have found to get the value for 'a' and display it on the page is to use the following:

{{ request()->get('a') }}

However, if you want to use it within an if statement, you could use:

@if( request()->get('a') )
    <script>console.log('hello')</script>
@endif

Hope that helps someone! :)

If you routinely use pandas, and aesthetics is preferred over performance, then consider the built-in function pandas.Series.drop_duplicates:

    import pandas as pd
    import numpy as np

    uniquifier = lambda alist: pd.Series(alist).drop_duplicates().tolist()

    # from the chosen answer 
    def f7(seq):
        seen = set()
        seen_add = seen.add
        return [ x for x in seq if not (x in seen or seen_add(x))]

    alist = np.random.randint(low=0, high=1000, size=10000).tolist()

    print uniquifier(alist) == f7(alist)  # True

Timing:

    In [104]: %timeit f7(alist)
    1000 loops, best of 3: 1.3 ms per loop
    In [110]: %timeit uniquifier(alist)
    100 loops, best of 3: 4.39 ms per loop

I did some search on this topic finally got some custom change

For MySQL workbench 6.3.7 Version Graphical inter phase is available

1. Start Workbench and select the connection.
2. Go to management or Instance and select Options File.
3. If Workbench ask you permission to read configuration file and then allow it by pressing OK two times.
4. At center place Administrator options file window comes.
5. Go To InnoDB tab and check the innodb_large_prefix if it not checked in the General section.
6. set innodb_default_row_format option value to DYNAMIC.

For Versions below 6.3.7 direct options are not available so need to go with command prompt

1. Start CMD as administrator.
2. Go To director where mysql server is install Most of cases its at "C:\Program Files\MySQL\MySQL Server 5.7\bin" so command is "cd \" "cd Program Files\MySQL\MySQL Server 5.7\bin".
3. Now Run command mysql -u userName -p databasescheema Now it asked for password of respective user. Provide password and enter into mysql prompt.
4. We have to set some global settings enter the below commands one by one set global innodb_large_prefix=on; set global innodb_file_format=barracuda; set global innodb_file_per_table=true;
5. Now at the last we have to alter the ROW_FORMAT of required table by default its COMPACT we have to set it to DYNAMIC.
6. use following command alter table table_name ROW_FORMAT=DYNAMIC;
7. Done

Try this :

use Illuminate\Support\Facades\Request;
public function add_question(Request $request)
{
    return $request->all();
}

Tiff images can be displayed directly onto IE and safari only.. no support of tiff images on chrome and firefox. you can encode the image and then display it on browser by decoding the encoded image to some other format. Hope this works for you

On Linux use below to test (it would replace the whitespaces with comma)

 sed 's/\s/,/g' /tmp/test.txt | head

later you can take the output into the file using below command:

sed 's/\s/,/g' /tmp/test.txt > /tmp/test_final.txt

PS: test is the file which you want to use

1. Use negative margins on the element you would like to minus pixels off. (desired element)
2. Make overflow:hidden; on the containing element
3. Switch to overflow:auto; on the desired element.

It worked for me!

The previous answers show 3 approaches

1. By creating a new data frame
2. By using "cbind"
3. By adding column "a", and sort data frame by columns using column names or indexes

Let me show #4 approach "By using "cbind" and "rename" that works for my case

1. Create data frame

df <- data.frame(b = c(1, 1, 1), c = c(2, 2, 2), d = c(3, 3, 3))

2. Get values for "new" column

new_column = c(0, 0, 0)

3. Combine "new" column with existed

df <- cbind(new_column, df)

4. Rename "new" column name

colnames(df)[1] <- "a"

If you can use JSONObject library, you could just

    JSONArray ja = new JSONArray("[{\"Date\":\"2012-1-4T00:00:00\",\"keywords\":null,\"NeededString\":\"this is the sample string I am needed for my project\",\"others\":\"not needed\"}]");
    String result = ja.getJSONObject(0).getString("NeededString");

To expand on the Wikipedia-based answers:

The Social Security Administration (SSA) explicitly states in this document that the having "000" in the first group of numbers "will NEVER be a valid SSN":

• http://www.socialsecurity.gov/employer/stateweb.htm

I'd consider that pretty definitive.

However, that the 2nd or 3rd groups of numbers won't be "00" or "0000" can be inferred from a FAQ that the SSA publishes which indicates that allocation of those groups starts at "01" or "0001":

• http://ssa-custhelp.ssa.gov/cgi-bin/ssa.cfg/php/enduser/std_adp.php?p_faqid=87

But this is only a FAQ and it's never outright stated that "00" or "0000" will never be used.

In another FAQ they provide (http://www.socialsecurity.gov/employer/randomizationfaqs.html#a0=6) that "00" or "0000" will never be used.

I can't find a reference to the 'advertisement' reserved SSNs on the SSA site, but it appears that no numbers starting with a 3 digit number higher than 772 (according to the document referenced above) have been assigned yet, but there's nothing I could find that states those numbers are reserved. Wikipedia's reference is a book that I don't have access to. The Wikipedia information on the advertisement reserved numbers is mentioned across the web, but many are clearly copied from Wikipedia. I think it would be nice to have a citation from the SSA, though I suspect that now that Wikipedia has made the idea popular that these number would now have to be reserved for advertisements even if they weren't initially.

The SSA has a page with a couple of stories about SSN's they've had to retire because they were used in advertisements/samples (maybe the SSA should post a link to whatever their current policy on this might be):

• http://www.ssa.gov/history/ssn/misused.html

In my case $(document).ready(function() was missing. Try this.

$(document).ready(function(){   
("#table tr").click(function(){
       $(this).addClass('selected').siblings().removeClass('selected');    
       var value=$(this).find('td:first').html();
       alert(value);    
    });
    $('.ok').on('click', function(e){
        alert($("#table tr.selected td:first").html());
    });
});

This is probably a rare case, but for me a library that was included in the settings.gradle was not there.

E.g. I had: include ':libraries:Android-RateThisApp:library' in my settings.gradle

but the folder Android-RateThisApp was empty. As soon as I checked out this submodule the gradle sync succeed.

If you transferred these files through disk or other means, it is likely they were not saved properly.

1. The first thing that you will need to do is remove the Podfile, Podfile.lock, the Pods folder, and the generated workspace.
2. Next, in the .xcodeproj, remove the references to the Pods.xcconfig files and the libPods.a file.
3. Within the Build Phases project tab, delete the Check Pods Manifest.lock section (open), Copy Pods Resources section (bottom) and Embed Pod Resources(bottom).
4. Remove Pods.framework.

The only thing you may want to do is include some of the libraries that you were using before. You can do this by simply draging whatever folders where in the pods folders into your project (I prefer to put them into my Supporting Files folder).

It worked for me.

You need to achieve that using CSS

Free read-only viewers:

• Large Text File Viewer (Windows) – Fully customizable theming (colors, fonts, word wrap, tab size). Supports horizontal and vertical split view. Also support file following and regex search. Very fast, simple, and has small executable size.
• klogg (Windows, macOS, Linux) – A maintained fork of glogg, its main feature is regular expression search. It can also watch files, allows the user to mark lines, and has serious optimizations built in. But from a UI standpoint, it's ugly and clunky.
• LogExpert (Windows) – "A GUI replacement for tail." It's really a log file analyzer, not a large file viewer, and in one test it required 10 seconds and 700 MB of RAM to load a 250 MB file. But its killer features are the columnizer (parse logs that are in CSV, JSONL, etc. and display in a spreadsheet format) and the highlighter (show lines with certain words in certain colors). Also supports file following, tabs, multifiles, bookmarks, search, plugins, and external tools.
• Lister (Windows) – Very small and minimalist. It's one executable, barely 500 KB, but it still supports searching (with regexes), printing, a hex editor mode, and settings.
• loxx (Windows) – Supports file following, highlighting, line numbers, huge files, regex, multiple files and views, and much more. The free version can not: process regex, filter files, synchronize timestamps, and save changed files.

Free editors:

• Your regular editor or IDE. Modern editors can handle surprisingly large files. In particular, Vim (Windows, macOS, Linux), Emacs (Windows, macOS, Linux), Notepad++ (Windows), Sublime Text (Windows, macOS, Linux), and VS Code (Windows, macOS, Linux) support large (~4 GB) files, assuming you have the RAM.
• Large File Editor (Windows) – Opens and edits TB+ files, supports Unicode, uses little memory, has XML-specific features, and includes a binary mode.
• GigaEdit (Windows) – Supports searching, character statistics, and font customization. But it's buggy – with large files, it only allows overwriting characters, not inserting them; it doesn't respect LF as a line terminator, only CRLF; and it's slow.

Builtin programs (no installation required):

• less (macOS, Linux) – The traditional Unix command-line pager tool. Lets you view text files of practically any size. Can be installed on Windows, too.
• Notepad (Windows) – Decent with large files, especially with word wrap turned off.
• MORE (Windows) – This refers to the Windows MORE, not the Unix more. A console program that allows you to view a file, one screen at a time.

Web viewers:

• readfileonline.com – Another HTML5 large file viewer. Supports search.

Paid editors:

• 010 Editor (Windows, macOS, Linux) – Opens giant (as large as 50 GB) files.
• SlickEdit (Windows, macOS, Linux) – Opens large files.
• UltraEdit (Windows, macOS, Linux) – Opens files of more than 6 GB, but the configuration must be changed for this to be practical: Menu » Advanced » Configuration » File Handling » Temporary Files » Open file without temp file...
• EmEditor (Windows) – Handles very large text files nicely (officially up to 248 GB, but as much as 900 GB according to one report).
• BssEditor (Windows) – Handles large files and very long lines. Don’t require an installation. Free for non commercial use.

Strings.xml file content:

However I would like to point out major implementation limitation here. If you are planning to put your javascript code in different file and include that file in your template. This won't work.

This works only when you main template and javascript code is in same file. Probably django team can address this limitation.

First, hstore is a contrib module, which only allows you to store key => value pairs, where keys and values can only be texts (however values can be sql NULLs too).

Both json & jsonb allows you to store a valid JSON value (defined in its spec).

F.ex. these are valid JSON representations: null, true, [1,false,"string",{"foo":"bar"}], {"foo":"bar","baz":[null]} - hstore is just a little subset compared to what JSON is capable (but if you only need this subset, it's fine).

The only difference between json & jsonb is their storage:

• json is stored in its plain text format, while
• jsonb is stored in some binary representation

There are 3 major consequences of this:

• jsonb usually takes more disk space to store than json (sometimes not)
• jsonb takes more time to build from its input representation than json
• json operations take significantly more time than jsonb (& parsing also needs to be done each time you do some operation at a json typed value)

When jsonb will be available with a stable release, there will be two major use cases, when you can easily select between them:

1. If you only work with the JSON representation in your application, PostgreSQL is only used to store & retrieve this representation, you should use json.
2. If you do a lot of operations on the JSON value in PostgreSQL, or use indexing on some JSON field, you should use jsonb.

You don't need to loop or to check anything. Just take a cube root of 12,000 and round it down:

r = int(12000**(1/3.0))
print r*r*r # 10648

I found that "_sleep(milliseconds);" (without the quotes) works well for Win32 if you include the chrono library

E.g:

#include <chrono>

using namespace std;

main
{
    cout << "text" << endl;
    _sleep(10000); // pauses for 10 seconds
}

Make sure you include the underscore before sleep.

If you have an object, you can easily create a FormData object and append the names and values from that object to formData.

You haven't posted any code, so it's a general example;

var form_data = new FormData();

for ( var key in item ) {
    form_data.append(key, item[key]);
}

$.ajax({
    url         : 'http://example.com/upload.php',
    data        : form_data,
    processData : false,
    contentType : false,
    type: 'POST'
}).done(function(data){
    // do stuff
});

There are more examples in the documentation on MDN

You need to set line-height.

<div style="border: 1px solid red;">
<span style="font-size: 38px; vertical-align:middle; float:left; line-height: 38px">Hejsan</span>
<span style="font-size: 13px; vertical-align:middle; float:right; line-height: 38px">svejsan</span>
<div style="clear: both;"></div>

http://jsfiddle.net/VBR5J/

Try this

myApp.config(['$httpProvider', function($httpProvider) {
        $httpProvider.defaults.useXDomain = true;
        delete $httpProvider.defaults.headers.common['X-Requested-With'];
    }
]);

Just setting useXDomain = true is not enough. AJAX request are also send with the X-Requested-With header, which indicate them as being AJAX. Removing the header is necessary, so the server is not rejecting the incoming request.

function printr($data)
{
   echo "<pre>";
      print_r($data);
   echo "</pre>";
}

And call your function on the page you need, don't forget to include the file where you put your function in for example: functions.php

include('functions.php');

printr($data);

Default log location (rhel) are

General messages:

/var/log/messages

Authentication messages:

/var/log/secure

Mail events:

Check your /etc/syslog.conf or /etc/syslog-ng.conf (it depends on which of syslog facility you have installed)

Example:

$ cat /etc/syslog.conf
# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none         /var/log/messages

# The authpriv file has restricted access.
authpriv.*                             /var/log/secure

# Log all the mail messages in one place.
mail.*                                 /var/log/maillog

#For a start, use this simplified approach.
*.*                                     /var/log/messages

Edit: EF Core 2.1 finally supports GroupBy

But always look out in the console / log for messages. If you see a notification that your query could not be converted to SQL and will be evaluated locally then you may need to rewrite it.

Entity Framework 7 (now renamed to Entity Framework Core 1.0 / 2.0) does not yet support GroupBy() for translation to GROUP BY in generated SQL (even in the final 1.0 release it won't). Any grouping logic will run on the client side, which could cause a lot of data to be loaded.

Eventually code written like this will automagically start using GROUP BY, but for now you need to be very cautious if loading your whole un-grouped dataset into memory will cause performance issues.

For scenarios where this is a deal-breaker you will have to write the SQL by hand and execute it through EF.

If in doubt fire up Sql Profiler and see what is generated - which you should probably be doing anyway.

https://blogs.msdn.microsoft.com/dotnet/2016/05/16/announcing-entity-framework-core-rc2

 img {
     display: block;
     margin-left: auto;
   }

You can also initialize data members at the point you declare them:

class another_example{
public:
    another_example();
    ~another_example();
private:
    int m_iInteger=10;
    double m_dDouble=10.765;
};

I use this form pretty much exclusively, although I have read some people consider it 'bad form', perhaps because it was only recently introduced - I think in C++11. To me it is more logical.

Another useful facet to the new rules is how to initialize data-members that are themselves classes. For instance suppose that CDynamicString is a class that encapsulates string handling. It has a constructor that allows you specify its initial value CDynamicString(wchat_t* pstrInitialString). You might very well use this class as a data member inside another class - say a class that encapsulates a windows registry value which in this case stores a postal address. To 'hard code' the registry key name to which this writes you use braces:

class Registry_Entry{
public:
    Registry_Entry();
    ~Registry_Entry();
    Commit();//Writes data to registry.
    Retrieve();//Reads data from registry;
private:
    CDynamicString m_cKeyName{L"Postal Address"};
    CDynamicString m_cAddress;
};

Note the second string class which holds the actual postal address does not have an initializer so its default constructor will be called on creation - perhaps automatically setting it to a blank string.

$array = @()
for($i=0; $i -lt 5; $i++)
{
    $array += $i
}

You can achieve this with the following snippet:

import java.lang.reflect.ParameterizedType;

public class SomeContainer<E> {
   E createContents() throws InstantiationException, IllegalAccessException {
      ParameterizedType genericSuperclass = (ParameterizedType)
         getClass().getGenericSuperclass();
      @SuppressWarnings("unchecked")
      Class<E> clazz = (Class<E>)
         genericSuperclass.getActualTypeArguments()[0];
      return clazz.newInstance();
   }
   public static void main( String[] args ) throws Throwable {
      SomeContainer< Long > scl = new SomeContainer<>();
      Long l = scl.createContents();
      System.out.println( l );
   }
}

I assigned the javascript in my Controller:

model.linkCode = "window.open('https://www.yahoo.com', '_blank')";

And in my view:

@section Scripts{
    <script @Html.CspScriptNonce()>

    $(function () {

        @if (!String.IsNullOrEmpty(Model.linkCode))
        {
            WriteLiteral(Model.linkCode);
        }
    });

That opened a new tab with the link, and went to it.

Interestingly, run locally it engaged a popup blocker, but seemed to work fine on the servers.

One more option if your id isn't autoincrement and you know which one to insert/update:

$object = MyModel::findOrNew($id);
//assign attributes to update...
$object->save();

This is what I used to copy some resource files: the copy-files is an empty target to ignore errors

    COMMAND ${CMAKE_COMMAND} -E copy_directory
    ${CMAKE_BINARY_DIR}/SOURCEDIRECTORY
    ${CMAKE_BINARY_DIR}/DESTINATIONDIRECTORY

6. After Adding the Rule go to your android studio -> inside your code URL(http://127.0.0.1:4880). Remember to change the port from 480 -> 4880.

7. Go to Remote Device Tab in Chrome and Click on your connected Device. Add New URL(127.0.0.1:4880) Inspect the Android Device Chrome Browser

Check your Actual Device Chrome Browser and start Debugging the code on Actual Android device.

I encountered the same question, and my solution was: add the JQuery script.

Especially, we should make sure the corresponding JQuery is loaded when we debug our js under the firefox/chrome.

Use the adb tool that comes with the SDK.

adb push myDirectory /sdcard/targetDir

If you only specify /sdcard/ (with the trailing slash) as destination, then the CONTENTS of myDirectory will end up in the root of /sdcard.

The best safe way is: <%= sanitize @x %>

It will avoid XSS!

In order to actually swap the escape key with the caps lock key (not just map one to the other) using both PCKeyboardHack and KeyRemap4MacBook, you have to follow the instructions in this thread, mapping the caps lock key to a keycode not used by the keyboard but accounted for by KeyRemap4MacBook (eg. 110). Then, in PCKeyboardHack, select the appropriate option that maps that keycode to escape (in the case of 110, it's "Application Key to Escape"). Here's what your KeyRemap4MacBook preferences should look like (provided you've selected the "show enabled only" checkbox).

I originally attempted to post this information as an edit to cwd's excellent answer, but it was rejected. I encourage anyone who wants to go the route that I describe to first read his/her response.

Yes, the value of any argument can be found using getArgs

@Before("execution(* com.mkyong.customer.bo.CustomerBo.addCustomer(..))")
public void logBefore(JoinPoint joinPoint) {

   Object[] signatureArgs = thisJoinPoint.getArgs();
   for (Object signatureArg: signatureArgs) {
      System.out.println("Arg: " + signatureArg);
      ...
   }
}

1. This is a vast subject. Do not underestimate this point. And do not underestimate my point to not underestimate it.
2. I hear the Dragon Book is a (the?) place to start, along with searching. :) Get better at searching, eventually it will be your life.
3. Building your own programming language is absolutely a good exercise! But know that it will never be used for any practical purpose in the end. Exceptions to this are few and very far between.

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

Try this:

REGEXP '^[a-z0-9]+$'

As regexp is not case sensitive except for binary fields.

To expand on John's answer you can also use the Dockerfile CMD command as following (in case you want it to self start without additional args)

CMD ["nginx", "-g", "daemon off;"]

use google Guava and do it in 2 lines:

import java.util.Map;
import com.google.common.base.Splitter;

public class Parser {
    public static void main(String... args) {
        String uri = "https://google.com.ua/oauth/authorize?client_id=SS&response_type=code&scope=N_FULL&access_type=offline&redirect_uri=http://localhost/Callback";
        String query = uri.split("\\?")[1];
        final Map<String, String> map = Splitter.on('&').trimResults().withKeyValueSeparator('=').split(query);
        System.out.println(map);
    }
}

which gives you

{client_id=SS, response_type=code, scope=N_FULL, access_type=offline, redirect_uri=http://localhost/Callback}

I assume that you are using MasterPage so within your master page you should have

<head runat="server">
    <asp:ContentPlaceHolder ID="head" runat="server">
    </asp:ContentPlaceHolder>
</head>

And within any of your pages based on that MasterPage add this

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
    <script src="js/yourscript.js" type="text/javascript"></script>
</asp:Content>

1. Select the <html> tag in Elements.
2. Do CTRL-C.
3. Check if there is only lefting <!DOCTYPE html> before the <html>.

Update: More useful information What does <meta http-equiv="X-UA-Compatible" content="IE=edge"> do?

Maybe this url can help you: Activating Browser Modes with Doctype

Edit: Today we were able to override the compatibility view with: <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />

jQuery API specifically says not to bind to beforeunload, and instead should bind directly to the window.onbeforeunload, I just ran across a pretty bad memory in part due binding to beforeunload with jQuery.

Also if you want to export inner json fields use dot (. operator).

JSON record:

{
    "_id" : "00118685076F2C77",
    "value" : {
        "userIds" : [ 
            "u1"
        ],
        "deviceId" : "dev"
}

mongoexport command with dot operator (using mongo version 3.4.7):

./mongoexport --host localhost --db myDB --collection myColl --type=csv --out out.csv --fields value.deviceId,value.userIds

Output csv:

value.deviceId,value.userIds
d1,"[""u1""]"
d2,"[""u2""]"

Note: Make sure you do not export an array. It would corrupt the CSV format like field userIds shown above

• Pro base64: the encoded representation you handle is a pretty safe string. It contains neither control chars nor quotes. The latter point helps against SQL injection attempts. I wouldn't expect any problem to just add the value to a "hand coded" SQL query string.

• Pro BLOB: the database manager software knows what type of data it has to expect. It can optimize for that. If you'd store base64 in a TEXT field it might try to build some index or other data structure for it, which would be really nice and useful for "real" text data but pointless and a waste of time and space for image data. And it is the smaller, as in number of bytes, representation.

Keep in mind that if you want to use the chrome inspect in Windows, besides enabling usb debugging on you mobile, you should also install the usb driver for Windows.

You can find the drivers you need from the list here:

http://androidxda.com/download-samsung-usb-drivers

Furthermore, you should use a newer version of Chrome mobile than the one in your Desktop.

There's a few ways (note this is not a complete list).

1) Single will return a single result, but will throw an exception if it finds none or more than one (which may or may not be what you want):

string search = "lookforme";
List<string> myList = new List<string>();
string result = myList.Single(s => s == search);

Note SingleOrDefault() will behave the same, except it will return null for reference types, or the default value for value types, instead of throwing an exception.

2) Where will return all items which match your criteria, so you may get an IEnumerable with one element:

IEnumerable<string> results = myList.Where(s => s == search);

3) First will return the first item which matches your criteria:

string result = myList.First(s => s == search);

Note FirstOrDefault() will behave the same, except it will return null for reference types, or the default value for value types, instead of throwing an exception.

I was using firefox and some reason, it was not taking the click command though from past 2months it was working. My feeling was to make use of sendKeys and this page solved the problem. Now I am using sendKeys(Keys.Enter)

Sometimes your json is not a string. For example if you are getting a json from a url like this:

j = urllib2.urlopen('http://site.com/data.json')

you will need to use json.load, not json.loads:

j_obj = json.load(j)

(it is easy to forget: the 's' is for 'string')

Both .ics and .vcs files are in ASCII. If you use "Save As" option to save a calendar entry (Appt, Meeting Request/Response/Postpone/Cancel and etc) in both .ics and .vcs format and use vimdiff, you can easily see the difference.

Both .vcs (vCal) and .ics (iCal) belongs to the same VCALENDAR camp, but .vcs file shows "VERSION:1.0" whereas .ics file uses "VERSION:2.0".

The spec for vCalendar v1.0 can be found at http://www.imc.org/pdi/pdiproddev.html. The spec for iCalendar (vCalendar v2.0) is in RFC5545. In general, the newer is better, and that is true for Outlook 2007 and onward, but not for Outlook 2003.

For Outlook 2003, the behavior is peculiar. It can save the same calendar entry in both .ics and .vcs format, but it only read & display .vcs file correctly. It can read .ics file but it omits some fields and does not display it in calendar mode. My guess is that back then Microsoft wanted to provide .ics to be compatible with Mac's iCal but not quite committed to v2.0 yet.

So I would say for Outlook 2003, .vcs is the native format.

Update: Nowadays installing is done with pip, but libyaml is still required to build the C extension (on mac):

brew install libyaml
python -m pip install pyyaml

Outdated method:

For MacOSX (mavericks), the following seems to work:

brew install libyaml
sudo python -m easy_install pyyaml

if you want to get the first document for each language field unique value, you can do this:

{
 "query": {
    "match_all": {

  },
  "collapse": {
    "field": "language.keyword",
    "inner_hits": {
    "name": "latest",
      "size": 1
    }
  }
}

To clear cookie and cache from Webview,

    // Clear all the Application Cache, Web SQL Database and the HTML5 Web Storage
    WebStorage.getInstance().deleteAllData();

    // Clear all the cookies
    CookieManager.getInstance().removeAllCookies(null);
    CookieManager.getInstance().flush();

    webView.clearCache(true);
    webView.clearFormData();
    webView.clearHistory();
    webView.clearSslPreferences();

If you have enough memory, I've found some performance gains by reading the entire file into a memory stream, and then opening a stream reader on that to read the lines. As long as you actually plan on reading the whole file anyway, this can yield some improvements.

There is no magic solution. C is not a reflective language. Objects don't automatically know what they are.

But you have many choices:

1. Obviously, add a parameter
2. Wrap the call in a macro and automatically add a parameter
3. Use a more complex object. Define a structure which contains the dynamic array and also the size of the array. Then, pass the address of the structure.

This selects elements that have the specified attribute with a value containing the given substring "ckbItem":

$('input[name *= ckbItem]').prop('checked', true);

It will select all elements that contain ckbItem in its name attribute.

This is built on some of the previous answers and comments. The following covers all the edge cases and fairly concise as well:

const isNumRegEx = /^-?(\d*\.)?\d+$/;

function isNumeric(n, allowScientificNotation = false) {
    return allowScientificNotation ? 
                !Number.isNaN(parseFloat(n)) && Number.isFinite(n) :
                isNumRegEx.test(n);
}

Populate the text box values in the Page Init event as opposed to using the Postback.

protected void Page_Init(object sender, EventArgs e)
{
    DropDownTitle();
}

I had the same issue on the Linux server I was working on. Connecting java to a X11 display worked on the head node, but not on any other. After contacting the administrator, it turned out that the current version of our job-scheduling system (SLURM) did not support X11 forwarding. They had to update SLURM (newer versions of SLURM support it) for it to work.

This is a FAQ:

//somexpression[$N]

means "Find every node selected by //somexpression that is the $Nth child of its parent".

What you want is:

(//input[@id="search_query"])[2]

Remember: The [] operator has higher precedence (priority) than the // abbreviation.

Closing a SpringApplication basically means closing the underlying ApplicationContext. The SpringApplication#run(String...) method gives you that ApplicationContext as a ConfigurableApplicationContext. You can then close() it yourself.

For example,

@SpringBootApplication
public class Example {
    public static void main(String[] args) {
        ConfigurableApplicationContext ctx = SpringApplication.run(Example.class, args);
        // ...determine it's time to shut down...
        ctx.close();
    }
}

Alternatively, you can use the static SpringApplication.exit(ApplicationContext, ExitCodeGenerator...) helper method to do it for you. For example,

@SpringBootApplication
public class Example {
    public static void main(String[] args) {
        ConfigurableApplicationContext ctx = SpringApplication.run(Example.class, args);
        // ...determine it's time to stop...
        int exitCode = SpringApplication.exit(ctx, new ExitCodeGenerator() {
            @Override
            public int getExitCode() {
                // no errors
                return 0;
            }
        });

        // or shortened to
        // int exitCode = SpringApplication.exit(ctx, () -> 0);

        System.exit(exitCode);
    }
}

It's because there is no long in javascript.

After reading this post, from Baeldung. I found that the solution is pretty simple.

What I have done, is to add the role and permissions into the GrantedAuthority. I was able to access both methods hasRole() and hasAuthority().

jQuery 1.6+

jQuery added a :focus selector so we no longer need to add it ourselves. Just use $("..").is(":focus")

jQuery 1.5 and below

Edit: As times change, we find better methods for testing focus, the new favorite is this gist from Ben Alman:

jQuery.expr[':'].focus = function( elem ) {
  return elem === document.activeElement && ( elem.type || elem.href );
};

Quoted from Mathias Bynens here:

Note that the (elem.type || elem.href) test was added to filter out false positives like body. This way, we make sure to filter out all elements except form controls and hyperlinks.

You're defining a new selector. See Plugins/Authoring. Then you can do:

if ($("...").is(":focus")) {
  ...
}

or:

$("input:focus").doStuff();

Any jQuery

If you just want to figure out which element has focus, you can use

$(document.activeElement)

If you aren't sure if the version will be 1.6 or lower, you can add the :focus selector if it is missing:

(function ( $ ) {
    var filters = $.expr[":"];
    if ( !filters.focus ) { 
        filters.focus = function( elem ) {
           return elem === document.activeElement && ( elem.type || elem.href );
        };
    }
})( jQuery );

That's because the return type for [data bytes] is a void* c-style array, not a Uint8 (which is what Byte is a typedef for).

The error is because you are trying to set an allocated array when the return is a pointer type, what you are looking for is the getBytes:length: call which would look like:

[data getBytes:&byteData length:len];

Which fills the array you have allocated with data from the NSData object.

The problem was in nulls in the values; then the concatenation does not work with nulls. The solution is as follows:

SELECT coalesce(a, '') || coalesce(b, '') FROM foo;

Ran into a issue with the HTTPClient, even with the suggestions still could not get it to authenticate. Turns out I needed a trailing '/' in my relative path.

i.e.

var result = await _client.GetStringAsync(_awxUrl + "api/v2/inventories/?name=" + inventoryName);

var result = await _client.PostAsJsonAsync(_awxUrl + "api/v2/job_templates/" + templateId+"/launch/" , new {
                inventory = inventoryId
            });

Have a look at C++11 Features (Modern C++)

and section "Quick Reference Guide to Visual C++ Version Numbers" ...

Position your <div> absolutely at the bottom and don't forget to give div.A a position: relative - http://jsfiddle.net/TTaMx/

    .A {
        position: relative;
        margin: 40px 0;
        height: 40px;
        width: 200px;
        background: #eee;
    }

    .A:after {
        content: " ";
        display: block;
        background: #c00;
        height: 29px;
        width: 100%;

        position: absolute;
        bottom: -29px;
    }?

When you are sure your script is perfectly working, you can get rid of warning and notices like this: Put this line at the beginning of your PHP script:

error_reporting(E_ERROR);

Before that, when working on your script, I would advise you to properly debug your script so that all notice or warning disappear one by one.

So you should first set it as verbose as possible with:

error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);

UPDATE: how to log errors instead of displaying them

As suggested in the comments, the better solution is to log errors into a file so only the PHP developer sees the error messages, not the users.

A possible implementation is via the .htaccess file, useful if you don't have access to the php.ini file (source).

# Suppress PHP errors
php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
php_value docref_root 0
php_value docref_ext 0

# Enable PHP error logging
php_flag  log_errors on
php_value error_log  /home/path/public_html/domain/PHP_errors.log

# Prevent access to PHP error log
<Files PHP_errors.log>
 Order allow,deny
 Deny from all
 Satisfy All
</Files>

https://github.com/requery/sqlite-android allows you to query JSON fields (and arrays in them, I've tried it and am using it). Before that I was just storing JSON strings into a TEXT column. It supports FTS3, FTS4, & JSON1

As of July 2019, it still gets version bumps every now and then, so it isn't a dead project.

• https://www.sqlite.org/json1.html (store and query JSON documents)
• https://www.sqlite.org/fts3.html (perform full-text searches)

For the record, here is an example using a sqlite database:

import pandas as pd
import sqlite3

with sqlite3.connect("whatever.sqlite") as con:
    sql = "SELECT * FROM table_name"
    df = pd.read_sql_query(sql, con)
    print df.shape

Here is a working solution - http://jsfiddle.net/STTaf/

I used simple jQuery:

$(function() {
    $('li').css('cursor', 'pointer')

    .click(function() {
        window.location = $('a', this).attr('href');
        return false;
    });
});

This:

var foo = new Foo();

and

var foo = Object.create(Foo.prototype);

are quite similar. One important difference is that new Foo actually runs constructor code, whereas Object.create will not execute code such as

function Foo() {
    alert("This constructor does not run with Object.create");
}

Note that if you use the two-parameter version of Object.create() then you can do much more powerful things.

The selector should not be #input. That means a field with id="input" which is not your case. You want:

$('#chag_sort').val(sort2);

Or if your hidden input didn't have an unique id but only a name="chag_sort":

$('input[name="chag_sort"]').val(sort2);

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

I got this error because I forgot the type="module" inside the script tag:

<script type="module" src="milsymbol-2.0.0/src/milsymbol.js"></script>

Have had the same problem happen to me twice now, the only fix sofa has been to restart the tomcat server and restart the build.

If the variable you are checking would be in the global scope you could do:

array_key_exists('v', $GLOBALS) 

Run this to find all instances of Xcode in your filesystem:

for i in find / -name Xcode -print; do echo $i; done

I use below approach and works fine for me,

class MyTableViewCell : UITableViewCell {

                var defaultStateColor:UIColor?
                var hitStateColor:UIColor?

                 override func awakeFromNib(){
                     super.awakeFromNib()
                     self.selectionStyle = .None
                 }

// if you are overriding init you should set selectionStyle = .None

                override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
                    if let hitColor = hitStateColor {
                        self.contentView.backgroundColor = hitColor
                    }
                }

                override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
                    if let defaultColor = defaultStateColor {
                        self.contentView.backgroundColor = defaultColor
                    }
                }

                override func touchesCancelled(touches: Set<UITouch>?, withEvent event: UIEvent?) {
                    if let defaultColor = defaultStateColor {
                        self.contentView.backgroundColor = defaultColor
                    }
                }
            }

Read this:

http://www.quora.com/OAuth-2-0/How-does-OAuth-2-0-work

or an even simpler but quick explanation:

http://agileanswer.blogspot.se/2012/08/oauth-20-for-my-ninth-grader.html

The redirect URI is the callback entry point of the app. Think about how OAuth for Facebook works - after end user accepts permissions, "something" has to be called by Facebook to get back to the app, and that "something" is the redirect URI. Furthermore, the redirect URI should be different than the initial entry point of the app.

The other key point to this puzzle is that you could launch your app from a URL given to a webview. To do this, i simply followed the guide on here:

http://iosdevelopertips.com/cocoa/launching-your-own-application-via-a-custom-url-scheme.html

and

http://inchoo.net/mobile-development/iphone-development/launching-application-via-url-scheme/

note: on those last 2 links, "http://" works in opening mobile safari but "tel://" doesn't work in simulator

in the first app, I call

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"secondApp://"]];

In my second app, I register "secondApp" (and NOT "secondApp://") as the name of URL Scheme, with my company as the URL identifier.

When hosted in docker containers (linux version for me), you might get a 'Connection Refused' message. In that case you can use IP address 0.0.0.0 which means "all IP addresses on this machine" instead of the localhost loopback to fix the port forwarding.

public class Program
{
    public static void Main(string[] args)
    {
        var host = new WebHostBuilder()
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseIISIntegration()
            .UseStartup<Startup>()
            .UseUrls("http://0.0.0.0:5000/")
            .Build();

        host.Run();
    }
}

Add %CATALINA_HOME%/bin to path system variable.

Go to Environment Variables screen under System Variables there will be a Path variable edit the variable and add ;%CATALINA_HOME%\bin to the variable then click OK to save the changes. Close all opened command prompts then open a new command prompt and try to use the command startup.bat.

The cin.clear() clears the error flag on cin (so that future I/O operations will work correctly), and then cin.ignore(10000, '\n') skips to the next newline (to ignore anything else on the same line as the non-number so that it does not cause another parse failure). It will only skip up to 10000 characters, so the code is assuming the user will not put in a very long, invalid line.

Fastest way for Android Studio 3.x.x and Android Studio 4.x.x

1.Go to the design tab of the activity layout

2.At the top you should press on the orientation for preview button, there is a option to create a landscape layout (check image), a new folder will be created as your xml layout file for that particular orientation

QR codes have three parameters: Datatype, size (number of 'pixels') and error correction level. How much information can be stored there also depends on these parameters. For example the lower the error correction level, the more information that can be stored, but the harder the code is to recognize for readers.

The maximum size and the lowest error correction give the following values:
Numeric only Max. 7,089 characters
Alphanumeric Max. 4,296 characters
Binary/byte Max. 2,953 characters (8-bit bytes)

That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:

DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87

Double check your table definition. Maybe you just missed adding something.

I also tried google-ing this problem and saw this:

Update 2019

The :has() pseudo-selector is propsed in the CSS Selectors 4 spec, and will address this use case once implemented.

To use it, we will write something like:

.foo > .bar:has(> .baz) { /* style here */ }

In a structure like:

<div class="foo">
  <div class="bar">
    <div class="baz">Baz!</div>
  </div>
</div>

This CSS will target the .bar div - because it both has a parent .foo and from its position in the DOM, > .baz resolves to a valid element target.

Original Answer (left for historical purposes) - this portion is no longer accurate

For completeness, I wanted to point out that in the Selectors 4 specification (currently in proposal), this will become possible. Specifically, we will gain Subject Selectors, which will be used in the following format:

!div > span { /* style here */

The ! before the div selector indicates that it is the element to be styled, rather than the span. Unfortunately, no modern browsers (as of the time of this posting) have implemented this as part of their CSS support. There is, however, support via a JavaScript library called Sel, if you want to go down the path of exploration further.

This answer changes with .NET 4.5. Creating a zip file becomes incredibly easy. No third-party libraries will be required.

string startPath = @"c:\example\start";
string zipPath = @"c:\example\result.zip";
string extractPath = @"c:\example\extract";

ZipFile.CreateFromDirectory(startPath, zipPath);
ZipFile.ExtractToDirectory(zipPath, extractPath);

For what it's worth I had this issue and had to go into cPanel where I saw the error message

"Attention! Please register your email IDs used in non-smtp mails through cpanel plugin. Unregistered email IDs will not be allowed in non-smtp emails sent through scripts. Go to Mail section and find "Registered Mail IDs" plugin in paper_lantern theme."

Registering the emails in cPanel (Register Mail IDs) and waiting 10 mins got mine to work.

Hope that helps someone.

If your function have two vector variables and must compute itself on each value of them (as mentioned by @Ari B. Friedman) you can use mapply as follows:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
mapply(mult_one,vars1,vars2)

which gives you:

> mapply(mult_one,vars1,vars2)
[1] 10 40 90

The answer you selected is correct, however if you are using a sorting table it will crash since rowInfo will became undefined as you search, would recommend using this function instead

                getTrGroupProps={(state, rowInfo, column, instance) => {
                    if (rowInfo !== undefined) {
                        return {
                            onClick: (e, handleOriginal) => {
                              console.log('It was in this row:', rowInfo)
                              this.setState({
                                  firstNameState: rowInfo.row.firstName,
                                  lastNameState: rowInfo.row.lastName,
                                  selectedIndex: rowInfo.original.id
                              })
                            },
                            style: {
                                cursor: 'pointer',
                                background: rowInfo.original.id === this.state.selectedIndex ? '#00afec' : 'white',
                                color: rowInfo.original.id === this.state.selectedIndex ? 'white' : 'black'
                            }
                        }
                    }}
                }

This is what myself and tekromancr came up with.

Example element:

<a href="http://www.google.com" id="btn" type="button" class="btn btn-disabled" data-placement="top" data-toggle="tooltip" data-title="I'm a tooltip">Press Me</a>

note: the tooltip attributes can be added to a separate div, in which the id of that div is to be used when calling .tooltip('destroy'); or .tooltip();

this enables the tooltip, put it in any javascript that is included in the html file. this line might not be necessary to add, however. (if the tooltip shows w/o this line then don't bother including it)

$("#element_id").tooltip();

destroys tooltip, see below for usage.

$("#element_id").tooltip('destroy');

prevents the button from being clickable. because the disabled attribute is not being used, this is necessary, otherwise the button would still be clickable even though it "looks" as if it is disabled.

$("#element_id").click(
  function(evt){
    if ($(this).hasClass("btn-disabled")) {
      evt.preventDefault();
      return false;
    }
  });

Using bootstrap, the classes btn and btn-disabled are available to you. Override these in your own .css file. you can add any colors or whatever you want the button to look like when disabled. Make sure you keep the cursor: default; you can also change what .btn.btn-success looks like.

.btn.btn-disabled{
    cursor: default;
}

add the code below to whatever javascript is controlling the button becoming enabled.

$("#element_id").removeClass('btn-disabled');
$("#element_id").addClass('btn-success');
$('#element_id).tooltip('destroy');

tooltip should now only show when the button is disabled.

if you are using angularjs i also have a solution for that, if desired.

On Windows add following lines to _vimrc

" store backup, undo, and swap files in temp directory
set directory=$HOME/temp//
set backupdir=$HOME/temp//
set undodir=$HOME/temp//

This is a clarification because I have seen things done in code which are honestly confusing - I think the following example might assist others.

As others have said before - Bitmap inherits from the Abstract Image class

Abstract effectively means you cannot create a New() instance of it.

    Image imgBad1 = new Image();        // Bad - won't compile
    Image imgBad2 = new Image(200,200); // Bad - won't compile

But you can do the following:

    Image imgGood;  // Not instantiated object!
    // Now you can do this
    imgGood = new Bitmap(200, 200);

You can now use imgGood as you would the same bitmap object if you had done the following:

    Bitmap bmpGood = new Bitmap(200,200);

The nice thing here is you can draw the imgGood object using a Graphics object

    Graphics gr = default(Graphics);
    gr = Graphics.FromImage(new Bitmap(1000, 1000));
    Rectangle rect = new Rectangle(50, 50, imgGood.Width, imgGood.Height); // where to draw
    gr.DrawImage(imgGood, rect);

Here imgGood can be any Image object - Bitmap, Metafile, or anything else that inherits from Image!

Use \t to add tab and \n for new line, here is a simple example below.

<string name="list_with_tab_tag">\tbanana\torange\tblueberry\tmango</string>
<string name="sentence_with_new_line_tag">This is the first sentence\nThis is the second scentence\nThis is the third sentence</string>

Bdizzle,

I would recommend that you read this link

You will see that Newsletters can have different widths, There seems to be no major standard, What is recommended is that the width will be about 95% of the page width, as different browsers use the extra margins differently. You will also find that email readers have problems when reading css so applying the guide lines in this tutorial might help you save some time and trouble-shooting down the road.

Be happy, Julian

-p|--parent will be used if you are trying to create a directory with top-down approach. That will create the parent directory then child and so on iff none exists.

-p, --parents no error if existing, make parent directories as needed

About rlidwka it means giving full or administrative access. Found it here https://itservices.stanford.edu/service/afs/intro/permissions/unix.

You can refer to the following article: http://www.wellho.net/mouth/3934_Multiple-identical-keys-in-a-Python-dict-yes-you-can-.html

In a dict, if a key is an object, there are no duplicate problems.

For example:

class p(object):
    def __init__(self, name):
        self.name = name
    def __repr__(self):
        return self.name
    def __str__(self):
        return self.name
d = {p('k'): 1, p('k'): 2}

Try this it may help you:

private void changeFragment(Fragment targetFragment){

    getSupportFragmentManager()
         .beginTransaction()
         .replace(R.id.main_fragment, targetFragment, "fragment")
         .setTransitionStyle(FragmentTransaction.TRANSIT_FRAGMENT_FADE)
         .commit();

}

you should use "append" mode redirection >> instead of >

This will give you the current screen based on the top left of the window just call this.CurrentScreen() to get info on the current screen.

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

namespace Common.Helpers
{
    public static class WindowHelpers
     {
        public static Screen CurrentScreen(this Window window)
         {
             return Screen.FromPoint(new System.Drawing.Point((int)window.Left,(int)window.Top));
         }
     }
}

I would just white list the characters.

^[a-zA-Z0-9äöüÄÖÜ]*$

Building a black list is equally simple with regex but you might need to add much more characters - there are a lot of Chinese symbols in unicode ... ;)

^[^<>%$]*$

The expression [^(many characters here)] just matches any character that is not listed.

Right click and open SVN Repo-browser:

Right click on Trunk (working copy) and choose Copy to...:

Input the respective branch's name/path:

Click OK, type the respective log message, and click OK.

If you in any doubt, have a look at JDK source code

ArrayList.clear() source code:

public void clear() {
    modCount++;

    // Let gc do its work
    for (int i = 0; i < size; i++)
        elementData[i] = null;

    size = 0;
}

You will see that size is set to 0 so you start from 0 position.

Please note that when adding elements to ArrayList, the backend array is extended (i.e. array data is copied to bigger array if needed) in order to be able to add new items. When performing ArrayList.clear() you only remove references to array elements and sets size to 0, however, capacity stays as it was.

Navigate to the folder on your new machine you want to download from git on git bash.

Use below command to download the code from any branch you like

git clone 'git ssh url' -b 'Branch Name'

It will download the respective branch code.

You can open it in a new window with window.open('https://support.wwf.org.uk/earth_hour/index.php?type=individual');. If you want to open it in new tab open the current page in two tabs and then alllow the script to run so that both current page and the new page will be obtained.

The simplest of all

Create a config.ts file

import { HttpHeaders } from '@angular/common/http';

export class Config {
    url: string = 'http://localhost:3000';
    httpOptions: any = {
        headers: new HttpHeaders({
           'Content-Type': 'application/json',
           'Authorization': JSON.parse(localStorage.getItem('currentUser')).token
        })
    }
}

Then on your service, just import the config.ts file

import { Config } from '../config';
import { HttpClient } from '@angular/common/http';

@Injectable()
export class OrganizationService {
  config = new Config;

  constructor(
    private http: HttpClient
  ) { }

  addData(data): Observable<any> {
     let sendAddLink = `${this.config.url}/api/addData`;

     return this.http.post(sendAddLink , data, this.config.httpOptions).pipe(
       tap(snap => {
      return snap;
        })
    );
 } 

I think it was the simplest and the safest.

You cannot store arrays in a vector or any other container. The type of the elements to be stored in a container (called the container's value type) must be both copy constructible and assignable. Arrays are neither.

You can, however, use an array class template, like the one provided by Boost, TR1, and C++0x:

std::vector<std::array<double, 4> >

(You'll want to replace std::array with std::tr1::array to use the template included in C++ TR1, or boost::array to use the template from the Boost libraries. Alternatively, you can write your own; it's quite straightforward.)

This should fulfill your requirements.

ABC:\s*(\(\D+\)\s*.*?)\\n

Here it is with some tests http://www.regexplanet.com/cookbook/ahJzfnJlZ2V4cGxhbmV0LWhyZHNyDgsSBlJlY2lwZRiEjiUM/index.html

Futher reading on regular expressions: http://www.regular-expressions.info/characters.html

Mysql isn't very clever. When you want to use the same timestamp in multiple update or insert queries, you need to declare a variable.

When you use the now() function, the system will call the current timestamp every time you call it in another query.

Reverse a string without python magic.

>>> def reversest(st):
    a=len(st)-1
    for i in st:
        print(st[a],end="")
        a=a-1

This is all you need.

 rsync -e ssh file host:/directory/.

As a little trick to know what you are obtaining you can use var, so the compiler will tell you the type to expect:

int a = 1;
int b = 2;
var result = a/b;

your compiler will tell you that result would be of type int here.

git remove or git rm can be used for this, with the --cached flag. Try:

git help rm

You can solve this issue be adding max-width:

#element {
   width: 100vw;
   height: 100vw;
   max-width: 100%;
}

When you using CSS to make the wrapper full width using the code width: 100vw; then you will notice a horizontal scroll in the page, and that happened because the padding and margin of html and body tags added to the wrapper size, so the solution is to add max-width: 100%

Proxies may send a HTTP_X_FORWARDED_FOR header but even that is optional.

Also keep in mind that visitors may share IP addresses; University networks, large companies and third-world/low-budget ISPs tend to share IPs over many users.

What you want is a SQL case statement. The form of these is either:

  select case [expression or column]
  when [value] then [result]
  when [value2] then [result2]
  else [value3] end

or:

  select case 
  when [expression or column] = [value] then [result]
  when [expression or column] = [value2] then [result2]
  else [value3] end

In your example you are after:

declare @temp as varchar(100)
set @temp='Measure'

select case @temp 
   when 'Measure' then Measure 
   else OtherMeasure end
from Measuretable

Comparing Java 7 and C# 3

(Some features of Java 7 aren't mentioned here, but the using statement advantage of all versions of C# over Java 1-6 has been removed.)

Not all of your summary is correct:

• In Java methods are virtual by default but you can make them final. (In C# they're sealed by default, but you can make them virtual.)
• There are plenty of IDEs for Java, both free (e.g. Eclipse, Netbeans) and commercial (e.g. IntelliJ IDEA)

Beyond that (and what's in your summary already):

• Generics are completely different between the two; Java generics are just a compile-time "trick" (but a useful one at that). In C# and .NET generics are maintained at execution time too, and work for value types as well as reference types, keeping the appropriate efficiency (e.g. a List<byte> as a byte[] backing it, rather than an array of boxed bytes.)
• C# doesn't have checked exceptions
• Java doesn't allow the creation of user-defined value types
• Java doesn't have operator and conversion overloading
• Java doesn't have iterator blocks for simple implemetation of iterators
• Java doesn't have anything like LINQ
• Partly due to not having delegates, Java doesn't have anything quite like anonymous methods and lambda expressions. Anonymous inner classes usually fill these roles, but clunkily.
• Java doesn't have expression trees
• C# doesn't have anonymous inner classes
• C# doesn't have Java's inner classes at all, in fact - all nested classes in C# are like Java's static nested classes
• Java doesn't have static classes (which don't have any instance constructors, and can't be used for variables, parameters etc)
• Java doesn't have any equivalent to the C# 3.0 anonymous types
• Java doesn't have implicitly typed local variables
• Java doesn't have extension methods
• Java doesn't have object and collection initializer expressions
• The access modifiers are somewhat different - in Java there's (currently) no direct equivalent of an assembly, so no idea of "internal" visibility; in C# there's no equivalent to the "default" visibility in Java which takes account of namespace (and inheritance)
• The order of initialization in Java and C# is subtly different (C# executes variable initializers before the chained call to the base type's constructor)
• Java doesn't have properties as part of the language; they're a convention of get/set/is methods
• Java doesn't have the equivalent of "unsafe" code
• Interop is easier in C# (and .NET in general) than Java's JNI
• Java and C# have somewhat different ideas of enums. Java's are much more object-oriented.
• Java has no preprocessor directives (#define, #if etc in C#).
• Java has no equivalent of C#'s ref and out for passing parameters by reference
• Java has no equivalent of partial types
• C# interfaces cannot declare fields
• Java has no unsigned integer types
• Java has no language support for a decimal type. (java.math.BigDecimal provides something like System.Decimal - with differences - but there's no language support)
• Java has no equivalent of nullable value types
• Boxing in Java uses predefined (but "normal") reference types with particular operations on them. Boxing in C# and .NET is a more transparent affair, with a reference type being created for boxing by the CLR for any value type.

This is not exhaustive, but it covers everything I can think of off-hand.

There's the NUMBERFORMATTER jQuery plugin, details below:

https://code.google.com/p/jquery-numberformatter/

From the above link:

This plugin is a NumberFormatter plugin. Number formatting is likely familiar to anyone who's worked with server-side code like Java or PHP and who has worked with internationalization.

EDIT: Replaced the link with a more direct one.

The HttpParams interface isn't there for specifying query string parameters, it's for specifying runtime behaviour of the HttpClient object.

If you want to pass query string parameters, you need to assemble them on the URL yourself, e.g.

new HttpGet(url + "key1=" + value1 + ...);

Remember to encode the values first (using URLEncoder).
