The error is:

Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])

In JSON, platforms look like this:

"platforms": [
    {
        "platform": "iphone"
    },
    {
        "platform": "ipad"
    },
    {
        "platform": "android_phone"
    },
    {
        "platform": "android_tablet"
    }
]

So try change your pojo to something like this:

private List platforms;

public List getPlatforms(){
    return this.platforms;
}

public void setPlatforms(List platforms){
    this.platforms = platforms;
}

EDIT: you will need change mobile_networks too. Will look like this:

private List mobile_networks;

public List getMobile_networks() {
    return mobile_networks;
}

public void setMobile_networks(List mobile_networks) {
    this.mobile_networks = mobile_networks;
}

Margin is applied to the outside of you element hence effecting how far your element is away from other elements.

Padding is applied to the inside of your element hence effecting how far your element's content is away from the border.

Also, using margin will not affect your element's dimensions whereas padding will make your elements dimensions (set height + padding) so for example if you have a 100x100px div with a 5 px padding, your div will actually be 105x105px

In Netbeans you can right click on the project and run it, but in IntelliJ IDEA you have to select the index.jsp file or the welcome file to run the project.

this is because Netbeans generate the following tag in web.xml and IntelliJ do not.

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

Other possible solution:

tv.setText(Integer.toString(a1));  // where a1 - int value

Yes, but you need to declare it readonly instead of const:

public static readonly string[] Titles = { "German", "Spanish", "Corrects", "Wrongs" };

The reason is that const can only be applied to a field whose value is known at compile-time. The array initializer you've shown is not a constant expression in C#, so it produces a compiler error.

Declaring it readonly solves that problem because the value is not initialized until run-time (although it's guaranteed to have initialized before the first time that the array is used).

Depending on what it is that you ultimately want to achieve, you might also consider declaring an enum:

public enum Titles { German, Spanish, Corrects, Wrongs };

I would prefer to keep the "Show Whitespace" button on the toolbar, so that in one click you can toggle it.

Go to Window -> Perspective -> Customize Perspective and enable to show the button on toolbar.

You can kill by job number. When you put a task in the background you'll see something like:

$ ./script &
[1] 35341

That [1] is the job number and can be referenced like:

$ kill %1
$ kill %%  # Most recent background job

To see a list of job numbers use the jobs command. More from man bash:

There are a number of ways to refer to a job in the shell. The character % introduces a job name. Job number n may be referred to as %n. A job may also be referred to using a prefix of the name used to start it, or using a substring that appears in its command line. For example, %ce refers to a stopped ce job. If a prefix matches more than one job, bash reports an error. Using %?ce, on the other hand, refers to any job containing the string ce in its command line. If the substring matches more than one job, bash reports an error. The symbols %% and %+ refer to the shell's notion of the current job, which is the last job stopped while it was in the foreground or started in the background. The previous job may be referenced using %-. In output pertaining to jobs (e.g., the output of the jobs command), the current job is always flagged with a +, and the previous job with a -. A single % (with no accompanying job specification) also refers to the current job.

 //working code from laravel 5.2

 public function store(Request $request)
 {
          $file = $request->file('file');
            if($file)
            {
                    $extension =  $file->clientExtension();
            }
            echo $extension;
 }

In the case where you don't know the locale of the string value received and it is not necessarily the same locale as the current default locale you can use this :

private static double parseDouble(String price){
    String parsedStringDouble;
    if (price.contains(",") && price.contains(".")){
        int indexOfComma = price.indexOf(",");
        int indexOfDot = price.indexOf(".");
        String beforeDigitSeparator;
        String afterDigitSeparator;
        if (indexOfComma < indexOfDot){
            String[] splittedNumber = price.split("\\.");
            beforeDigitSeparator = splittedNumber[0];
            afterDigitSeparator = splittedNumber[1];
        }
        else {
            String[] splittedNumber = price.split(",");
            beforeDigitSeparator = splittedNumber[0];
            afterDigitSeparator = splittedNumber[1];
        }
        beforeDigitSeparator = beforeDigitSeparator.replace(",", "").replace(".", "");
        parsedStringDouble = beforeDigitSeparator+"."+afterDigitSeparator;
    }
    else {
        parsedStringDouble = price.replace(",", "");
    }

    return Double.parseDouble(parsedStringDouble);

}

It will return a double no matter what the locale of the string is. And no matter how many commas or points there are. So passing 1,000,000.54 will work so will 1.000.000,54 so you don't have to rely on the default locale for parsing the string anymore. The code isn't as optimized as it can be so any suggestions are welcome. I tried to test most of the cases to make sure it solves the problem but I am not sure it covers all. If you find a breaking value let me know.

If you want to automatically/periodically clean up exited containers and remove images and volumes that aren't in use by a running container you can download the Docker image meltwater/docker-cleanup.

That way you don't need to go clean it up by hand.

Just run:

docker run -d -v /var/run/docker.sock:/var/run/docker.sock:rw  -v /var/lib/docker:/var/lib/docker:rw --restart=unless-stopped meltwater/docker-cleanup:latest

It will run every 30 minutes (or however long you set it using DELAY_TIME=1800 option) and clean up exited containers and images.

More details: https://github.com/meltwater/docker-cleanup/blob/master/README.md

Google is full of information on this. As Hans Passant said, Form controls are built in to Excel whereas ActiveX controls are loaded separately.

Generally you'll use Forms controls, they're simpler. ActiveX controls allow for more flexible design and should be used when the job just can't be done with a basic Forms control.

Many user's computers by default won't trust ActiveX, and it will be disabled; this sometimes needs to be manually added to the trust center. ActiveX is a microsoft-based technology and, as far as I'm aware, is not supported on the Mac. This is something you'll have to also consider, should you (or anyone you provide a workbook to) decide to use it on a Mac.

The behaviour is not defined, so you must explicit set a commit or a rollback:

http://docs.oracle.com/cd/B10500_01/java.920/a96654/basic.htm#1003303

"If auto-commit mode is disabled and you close the connection without explicitly committing or rolling back your last changes, then an implicit COMMIT operation is executed."

Hsqldb makes a rollback

con.setAutoCommit(false);
stmt.executeUpdate("insert into USER values ('" +  insertedUserId + "','Anton','Alaf')");
con.close();

result is

2011-11-14 14:20:22,519 main INFO [SqlAutoCommitExample:55] [AutoCommit enabled = false] 2011-11-14 14:20:22,546 main INFO [SqlAutoCommitExample:65] [Found 0# users in database]

Although this isn't using the np array format, (to lazy to modify my code) this should do what you want... If, you truly want a column vector you will want to transpose the vector result. It all depends on how you are planning to use this.

def getVector(data_array,col):
    vector = []
    imax = len(data_array)
    for i in range(imax):
        vector.append(data_array[i][col])
    return ( vector )
a = ([1,2,3], [4,5,6])
b = getVector(a,1)
print(b)

Out>[2,5]

So if you need to transpose, you can do something like this:

def transposeArray(data_array):
    # need to test if this is a 1D array 
    # can't do a len(data_array[0]) if it's 1D
    two_d = True
    if isinstance(data_array[0], list):
        dimx = len(data_array[0])
    else:
        dimx = 1
        two_d = False
    dimy = len(data_array)
    # init output transposed array
    data_array_t = [[0 for row in range(dimx)] for col in range(dimy)]
    # fill output transposed array
    for i in range(dimx):
        for j in range(dimy):
            if two_d:
                data_array_t[j][i] = data_array[i][j]
            else:
                data_array_t[j][i] = data_array[j]
    return data_array_t

My solution is a wrapper around app.route:

def corsapp_route(path, origin=('127.0.0.1',), **options):
    """
    Flask app alias with cors
    :return:
    """

    def inner(func):
        def wrapper(*args, **kwargs):
            if request.method == 'OPTIONS':
                response = make_response()
                response.headers.add("Access-Control-Allow-Origin", ', '.join(origin))
                response.headers.add('Access-Control-Allow-Headers', ', '.join(origin))
                response.headers.add('Access-Control-Allow-Methods', ', '.join(origin))
                return response
            else:
                result = func(*args, **kwargs)
            if 'Access-Control-Allow-Origin' not in result.headers:
                result.headers.add("Access-Control-Allow-Origin", ', '.join(origin))
            return result

        wrapper.__name__ = func.__name__

        if 'methods' in options:
            if 'OPTIONS' in options['methods']:
                return app.route(path, **options)(wrapper)
            else:
                options['methods'].append('OPTIONS')
                return app.route(path, **options)(wrapper)

        return wrapper

    return inner

@corsapp_route('/', methods=['POST'], origin=['*'])

Value of textarea is also taken with val method:

Other answers are doing a good job of summarizing the requirements of main. I want to gather references to where those requirements are documented.

The most authoritative source is the VM spec (second edition cited). As main is not a language feature, it is not considered in the Java Language Specification.

• 2.17.1 Execution - Virtual Machine Start-up
• 5.2 Virtual Machine Start-up

Another good resource is the documentation for the application launcher itself:

• java - the Java application launcher

echo date("l M j, Y",$res1['timep']);
This is really good for converting a unix timestamp to a readable date along with day. Example: Thursday Jul 7, 2016

Above answers works fine. Here is another approach when we have lot of branches in local repo and we have to delete many branches except few which are lying in local machine.

First git branch will list all the local branches.

To transpose the column of branch names into single row in file by running a unix command
git branch > sample.txt
This will save it in sample.txt file. And run
awk 'BEGIN { ORS = " " } { print }' sample.txt
command in shell. This will transform the column to row and copy the list of branch names in single row.

And then run
git branch -D branch_name(s).
This will delete all listed branches present in local

I don't believe you can do just a string, but if you put the string inside of a <span> with the correct attributes (size, font-weight, etc); you should then be able to use jQuery to get the width of the span.

<span id='string_span' style='font-weight: bold; font-size: 12'>Here is my string</span>
<script>
  $('#string_span').width();
</script>

My first answer!

This will set the safemode switch:

bcdedit /set {current} safeboot minimal 

with networking:

bcdedit /set {current} safeboot network

then reboot the machine with

shutdown /r

to put back in normal mode via dos:

bcdedit /deletevalue {current} safeboot

While this question was asked a while ago and I don't know the state of the libraries at that point, it is worth mentioning for searchers that GitPython does a good job of abstracting the command line tools so that you don't need to use subprocess. There are some useful built in abstractions that you can use, but for everything else you can do things like:

import git
repo = git.Repo( '/home/me/repodir' )
print repo.git.status()
# checkout and track a remote branch
print repo.git.checkout( 'origin/somebranch', b='somebranch' )
# add a file
print repo.git.add( 'somefile' )
# commit
print repo.git.commit( m='my commit message' )
# now we are one commit ahead
print repo.git.status()

Everything else in GitPython just makes it easier to navigate. I'm fairly well satisfied with this library and appreciate that it is a wrapper on the underlying git tools.

UPDATE: I've switched to using the sh module for not just git but most commandline utilities I need in python. To replicate the above I would do this instead:

import sh
git = sh.git.bake(_cwd='/home/me/repodir')
print git.status()
# checkout and track a remote branch
print git.checkout('-b', 'somebranch')
# add a file
print git.add('somefile')
# commit
print git.commit(m='my commit message')
# now we are one commit ahead
print git.status()

When you do the for/in loop you put up first, i is the property name. So you have the property name, i, and access the value by doing myObject[i].

Try this:

<li onclick="myfunction(this)">

function myfunction(li) {
    var TextInsideLi = li.getElementsByTagName('p')[0].innerHTML;
}

A FragmentActivity is a subclass of Activity that was built for the Android Support Package.

The FragmentActivity class adds a couple new methods to ensure compatibility with older versions of Android, but other than that, there really isn't much of a difference between the two. Just make sure you change all calls to getLoaderManager() and getFragmentManager() to getSupportLoaderManager() and getSupportFragmentManager() respectively.

You have to tell your compiler where is the include directory. Something like this:

gcc -I/usr/lib/jvm/jdk1.7.0_07/include

But it depends on your makefile.

As id is the primary key, you cannot have different rows with the same value. Try to change your table so that the id is auto incremented:

id int NOT NULL AUTO_INCREMENT

and then set the primary key as follows:

PRIMARY KEY (id)

All together:

CREATE TABLE card_games (
   id int(11) NOT NULL AUTO_INCREMENT,
   nafnleiks varchar(50),
   leiklysing varchar(3000), 
   prentadi varchar(1500), 
   notkunarheimildir varchar(1000),
   upplysingar varchar(1000),
   ymislegt varchar(500),
   PRIMARY KEY (id));

Otherwise, you can indicate the id in every insertion, taking care to set a different value every time:

insert into card_games (id, nafnleiks, leiklysing, prentadi, notkunarheimildir, upplysingar, ymislegt)

values(1, 'Svartipétur', 'Leiklýsingu vantar', 'Er prentað í: Þórarinn Guðmundsson (2010). Spilabókin - Allir helstu spilaleikir og spil.', 'Heimildir um notkun: Árni Sigurðsson (1951). Hátíðir og skemmtanir fyrir hundrað árum', 'Aðrar upplýsingar', 'ekkert hér sem stendur' );

SQL Server 2008 R2:

For an existing database that you wish to "restore: from a backup of a different database follow these steps:

1. From the toolbar, click the Activity Monitor button.
2. Click processes. Filter by the database you want to restore. Kill all running processes by right clicking on each process and selecting "kill process".
3. Right click on the database you wish to restore, and select Tasks-->Restore-->From Database.
4. Select the "From Device:" radio button.
5. Select ... and choose the backup file of the other database you wish to restore from.
6. Select the backup set you wish to restore from by selecting the check box to the left of the backup set.
7. Select "Options".
8. Select Overwrite the existing database (WITH REPLACE)
9. Important: Change the "Restore As" Rows Data file name to the file name of the existing database you wish to overwrite or just give it a new name.
10. Do the same with the log file file name.
11. Verify from the Activity Monitor Screen that no new processes were spawned. If they were, kill them.
12. Click OK.

Use awk with a flag to trigger the print when necessary:

$ awk '/abc/{flag=1;next}/mno/{flag=0}flag' file
def1
ghi1
jkl1
def2
ghi2
jkl2

How does this work?

• /abc/ matches lines having this text, as well as /mno/ does.
• /abc/{flag=1;next} sets the flag when the text abc is found. Then, it skips the line.
• /mno/{flag=0} unsets the flag when the text mno is found.
• The final flag is a pattern with the default action, which is to print $0: if flag is equal 1 the line is printed.

For a more detailed description and examples, together with cases when the patterns are either shown or not, see How to select lines between two patterns?.

If you want the underline to be present while the mouse hovers over the link, then:

a:hover {text-decoration: underline; }

is sufficient, however you can also use a class-name of 'hover' if you wish, and the following would be equally applicable:

a.hover:hover {text-decoration: underline; }

Incidentally it may be worth pointing out that the class name of 'hover' doesn't really add anything to the element, as the psuedo-element of a:hover does the same thing as that of a.hover:hover. Unless it's just a demonstration of using a class-name.

As already stated there is nothing you can do except restore from a backup. At least now you will have learned to always wrap statements in a transaction to see what happens before you decide to commit. Also, if you don't have a backup of your database this will also teach you to make regular backups of your database.

While we haven't been much help for your imediate problem...hopefully these answers will ensure you don't run into this problem again in the future.

I faced the same problem and never worked for me except until go to the emulator folder, I tried to export the emulator folder but not worked for me

Hope So this logic will help some one.

Straight out from the documentation:

Suppose the website example.com would like to send notifications to its users via a Telegram bot. Here's what they could do to enable notifications for a user with the ID 123.

1. Create a bot with a suitable username, e.g. @ExampleComBot
2. Set up a webhook for incoming messages
3. Generate a random string of a sufficient length, e.g. $memcache_key = "vCH1vGWJxfSeofSAs0K5PA"
4. Put the value 123 with the key $memcache_key into Memcache for 3600 seconds (one hour)
5. Show our user the button https://telegram.me/ExampleComBot?start=vCH1vGWJxfSeofSAs0K5PA
6. Configure the webhook processor to query Memcached with the parameter that is passed in incoming messages beginning with /start. If the key exists, record the chat_id passed to the webhook as telegram_chat_id for the user 123. Remove the key from Memcache.
7. Now when we want to send a notification to the user 123, check if they have the field telegram_chat_id. If yes, use the sendMessage method in the Bot API to send them a message in Telegram.

There's another layout manager that may be of interest here: Overlay Layout Here's a simple tutorial: OverlayLayout: for layout management of components that lie on top of one another. Overlay Layout allows you to position panels on top of one another, and set a layout inside each panel. You are also able to set size and position of each panel separately.

(The reason I'm answering this question from years ago is because I have stumbled upon the same problem, and I have seen very few mentions of the Overlay Layout on StackOverflow, while it seems to be pretty well documented. Hopefully this may help someone else who keeps searching for it.)

"not equal" So in this case, $RESULT is tested to not be equal to zero.

However, the test is done numerically, not alphabetically:

n1 -ne n2     True if the integers n1 and n2 are not algebraically equal.

compared to:

s1 != s2      True if the strings s1 and s2 are not identical.

In first statement you define variable, which common for all of the objects (class static field).

In the second statement you define variable, which belongs to each created object (a lot of copies).

In your case you should use the first one.

If you're sharing code between C and C++, remember to add the following to the shared.hfile:

#ifdef __cplusplus
extern "C" {
#endif

extern int my_global;
/* other extern declarations ... */

#ifdef __cplusplus
}

alter table table_name 
add( "NISFLAG"    NUMBER(1,0) )

comment on column "ELIXIR"."PRD_INFO_1"."NISPRODGSTAPPL" is 'comment here'

commit;

Best way for Oracle:

With hardcoded datetime:

SELECT TO_CHAR(CAST((FROM_TZ(CAST(TO_DATE('2018-10-27 21:00', 'YYYY-MM-DD HH24:MI') AS TIMESTAMP), 'UTC') AT  TIME ZONE 'EET') AS DATE), 'YYYY-MM-DD HH24:MI') UTC_TO_EET FROM DUAL

Result: 2018-10-28 00:00

With column and table names:

SELECT TO_CHAR(CAST((FROM_TZ(CAST(COLUMN_NAME AS TIMESTAMP), 'UTC') AT  TIME ZONE 'EET') AS DATE), 'YYYY-MM-DD HH24:MI') UTC_TO_EET FROM TABLE_NAME

It wont break if you wrap each item in a div. Check out my fiddle with the link below. I made the width of the fieldset 125px and made each item 50px wide. You'll see the label and checkbox remain side by side on a new line and don't break.

<fieldset>
<div class="item">
    <input type="checkbox" id="a">
    <label for="a">a</label>
</div>
<div class="item">
   <input type="checkbox" id="b">
<!-- depending on width, a linebreak can occur here. -->
    <label for="b">bgf bh fhg fdg hg dg gfh dfgh</label>
</div>
<div class="item">
    <input type="checkbox" id="c">
    <label for="c">c</label>
</div>
</fieldset>

I thought my Git windows screen was struck but actually a sign in prompt comes behind it.Check for it and enter your credentials and that's it.

Dynatrace AJAX Edition shows you the exact sequence of page loading, parsing and execution.

Updating an entry:

A simple increment should do the trick.

UPDATE mytable 
  SET logins = logins + 1 
  WHERE id = 12

Insert new row, or Update if already present:

If you would like to update a previously existing row, or insert it if it doesn't already exist, you can use the REPLACE syntax or the INSERT...ON DUPLICATE KEY UPDATE option (As Rob Van Dam demonstrated in his answer).

Inserting a new entry:

Or perhaps you're looking for something like INSERT...MAX(logins)+1? Essentially you'd run a query much like the following - perhaps a bit more complex depending on your specific needs:

INSERT into mytable (logins) 
  SELECT max(logins) + 1 
  FROM mytable

you can use localStorage for storing the json data:

the example is given below:-

let JSONDatas = [
    {"id": "Open"},
    {"id": "OpenNew", "label": "Open New"},
    {"id": "ZoomIn", "label": "Zoom In"},
    {"id": "ZoomOut", "label": "Zoom Out"},
    {"id": "Find", "label": "Find..."},
    {"id": "FindAgain", "label": "Find Again"},
    {"id": "Copy"},
    {"id": "CopyAgain", "label": "Copy Again"},
    {"id": "CopySVG", "label": "Copy SVG"},
    {"id": "ViewSVG", "label": "View SVG"}
]

localStorage.setItem("datas", JSON.stringify(JSONDatas));

let data = JSON.parse(localStorage.getItem("datas"));

console.log(data);

So to add the string hello to a list as individual characters, try this:

newlist = []
newlist[:0] = 'hello'
print (newlist)

  ['h','e','l','l','o']

However, it is easier to do this:

splitlist = list(newlist)
print (splitlist)

Another similar way to do it by css:

#img {  }_x000D_
#img:hover {visibility:hidden}_x000D_
#thistext {font-size:22px;color:white }_x000D_
#thistext:hover {color:black;}_x000D_
#hoverme {width:50px;height:50px;}_x000D_
_x000D_
#hoverme:hover { _x000D_
background-color:green;_x000D_
position:absolute ;_x000D_
left:300px;_x000D_
top:100px;_x000D_
width:40%;_x000D_
height:20%;_x000D_
}

<p id="hoverme"><img id="img" src="http://a.deviantart.net/avatars/l/o/lol-cat.jpg"></img><span id="thistext">LOCATZ!!!!</span></p>

And here is some links about transitions and new ways to do it: http://www.w3schools.com/css3/css3_transitions.asp http://dev.opera.com/articles/view/css3-show-and-hide/

For most common markdown generators. You have a simple self generated anchor in each header. For instance with pandoc, the generated anchor will be a kebab case slug of your header.

 echo "# Hello, world\!" | pandoc
 # => <h1 id="hello-world">Hello, world!</h1>

Depending on which markdown parser you use, the anchor can change (take the exemple of symbolrush and La muerte Peluda answers, they are different!). See this babelmark where you can see generated anchors depending on your markdown implementation.

The difference between memcpy and memmove is that

1. in memmove, the source memory of specified size is copied into buffer and then moved to destination. So if the memory is overlapping, there are no side effects.

2. in case of memcpy(), there is no extra buffer taken for source memory. The copying is done directly on the memory so that when there is memory overlap, we get unexpected results.

These can be observed by the following code:

//include string.h, stdio.h, stdlib.h
int main(){
  char a[]="hare rama hare rama";

  char b[]="hare rama hare rama";

  memmove(a+5,a,20);
  puts(a);

  memcpy(b+5,b,20);
  puts(b);
}

Output is:

hare hare rama hare rama
hare hare hare hare hare hare rama hare rama

If you know the number of elements per "row" and the width of the container you can use a selector to add a margin to the elements you need to cause a justified look.

I had rows of three divs I wanted justified so used the:

.tile:nth-child(3n+2) { margin: 0 10px }

this allows the center div in each row to have a margin that forces the 1st and 3rd div to the outside edges of the container

Also great for other things like borders background colors etc

From git reset

"pull" or "merge" always leaves the original tip of the current branch in ORIG_HEAD.

git reset --hard ORIG_HEAD

Resetting hard to it brings your index file and the working tree back to that state, and resets the tip of the branch to that commit.

git reset --merge ORIG_HEAD

After inspecting the result of the merge, you may find that the change in the other branch is unsatisfactory. Running "git reset --hard ORIG_HEAD" will let you go back to where you were, but it will discard your local changes, which you do not want. "git reset --merge" keeps your local changes.

Before any patches are applied, ORIG_HEAD is set to the tip of the current branch.
This is useful if you have problems with multiple commits, like running 'git am' on the wrong branch or an error in the commits that is more easily fixed by changing the mailbox (e.g. +errors in the "From:" lines).

In addition, merge always sets '.git/ORIG_HEAD' to the original state of HEAD so a problematic merge can be removed by using 'git reset ORIG_HEAD'.

Note: from here

HEAD is a moving pointer. Sometimes it means the current branch, sometimes it doesn't.

So HEAD is NOT a synonym for "current branch" everywhere already.

HEAD means "current" everywhere in git, but it does not necessarily mean "current branch" (i.e. detached HEAD).

But it almost always means the "current commit".
It is the commit "git commit" builds on top of, and "git diff --cached" and "git status" compare against.
It means the current branch only in very limited contexts (exactly when we want a branch name to operate on --- resetting and growing the branch tip via commit/rebase/etc.).

Reflog is a vehicle to go back in time and time machines have interesting interaction with the notion of "current".

HEAD@{5.minutes.ago} could mean "dereference HEAD symref to find out what branch we are on RIGHT NOW, and then find out where the tip of that branch was 5 minutes ago".
Alternatively it could mean "what is the commit I would have referred to as HEAD 5 minutes ago, e.g. if I did "git show HEAD" back then".

git1.8.4 (July 2013) introduces introduced a new notation!
(Actually, it will be for 1.8.5, Q4 2013: reintroduced with commit 9ba89f4), by Felipe Contreras.

Instead of typing four capital letters "HEAD", you can say "@" now,
e.g. "git log @".

See commit cdfd948

Typing 'HEAD' is tedious, especially when we can use '@' instead.

The reason for choosing '@' is that it follows naturally from the ref@op syntax (e.g. HEAD@{u}), except we have no ref, and no operation, and when we don't have those, it makes sens to assume 'HEAD'.

So now we can use 'git show @~1', and all that goody goodness.

Until now '@' was a valid name, but it conflicts with this idea, so let's make it invalid. Probably very few people, if any, used this name.

SELECT *
FROM logs
WHERE pw='correct'
  AND CASE
          WHEN id<800 THEN success=1
          ELSE 1=1
      END
  AND YEAR(TIMESTAMP)=2011

This will open up the debugger, open the file and then run the debugger in the GUI mode.

According to https://bugzilla.mozilla.org/show_bug.cgi?id=592284, the pref network.http.connection-retry-timeout controls the amount of time in ms (Milliseconds !) to wait for success on the initial connection before beginning the second one. Setting it to 0 disables the parallel connection.

A boolean is not an integer; 1 and 0 are not boolean values in Java. You'll need to convert them explicitly:

boolean multipleContacts = (1 == jsonObject.getInt("MultipleContacts"));

or serialize the ints as booleans from the start.

I have two solutions for this Question.

1. The first solution is on getting display names from enum.

public enum CourseLocationTypes
{
    [Display(Name = "On Campus")]
    OnCampus,
    [Display(Name = "Online")]
    Online,
    [Display(Name = "Both")]
    Both
}

public static string DisplayName(this Enum value)
{
    Type enumType = value.GetType();
    string enumValue = Enum.GetName(enumType, value);
    MemberInfo member = enumType.GetMember(enumValue)[0];

    object[] attrs = member.GetCustomAttributes(typeof(DisplayAttribute), false);
    string outString = ((DisplayAttribute)attrs[0]).Name;

    if (((DisplayAttribute)attrs[0]).ResourceType != null)
    {
        outString = ((DisplayAttribute)attrs[0]).GetName();
    }

    return outString;
}

<h3 class="product-title white">@Model.CourseLocationType.DisplayName()</h3>

2. The second Solution is on getting display name from enum name but that will be enum split in developer language it's called patch.

public static string SplitOnCapitals(this string text)
{
        var r = new Regex(@"
            (?<=[A-Z])(?=[A-Z][a-z]) |
             (?<=[^A-Z])(?=[A-Z]) |
             (?<=[A-Za-z])(?=[^A-Za-z])", RegexOptions.IgnorePatternWhitespace);

        return r.Replace(text, " ");
}

 <div class="widget-box pt-0">
     @foreach (var item in Enum.GetNames(typeof(CourseLocationType)))
     {
         <label class="pr-2 pt-1">
             @Html.RadioButtonFor(x => x.CourseLocationType, item, new { type = "radio", @class = "iCheckBox control-label" })&nbsp; @item.SplitOnCapitals()
         </label>
     }
     @Html.ValidationMessageFor(x => x.CourseLocationType)
 </div>

Either you set LDAP_DOMAIN variable or you misconfigured it. Jump inside of ldap machine/container and run:

slapcat > backup.ldif

If it fails, check punctuation, quotes etc while you assigned variable "LDAP_DOMAIN" Otherwise you will find answer inside on backup.ldif file.

For me This was the solution on macOS ReInstall the psql

brew install postgres

Start PostgreSQL server

pg_ctl -D /usr/local/var/postgres start

Initialize DB

initdb /usr/local/var/postgres

If this command throws an error the rm the old database file and re-run the above command

rm -r /usr/local/var/postgres

Create a new database

createdb postgres_test
psql -W postegres_test

You will be logged into this db and can create a user in here to login

If your current min. API level is 23, you can simply use getColor() like we are using for getString():

//example
textView.setTextColor(getColor(R.color.green));
// if context is not available(ex: not in activity) use with context.getColor()

If you want below API level 23, just use this:

textView.setTextColor(getResources().getColor(R.color.green));

But note that getResources().getColor() is deprecated in API Level 23. In that case replace above with:

textView.setTextColor(ContextCompat.getColor(this /*context*/, R.color.green)) //Im in an activity, so I can use `this`

ContextCompat: Helper for accessing features in Context

If You want, you can constraint with SDK_INT like below:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    textView.setTextColor(getColor(R.color.green));
} else {
    textView.setTextColor(getResources().getColor(R.color.green));
}

set number set nonumber

DO work inside .vimrc and make sure you DO NOT precede commands in .vimrc with :

for the first question

$key = 'Home';
echo $key." is at ".$page[$key];

I know I should not necromancy on a subject, but given the details of the question, I usually expand it to mean:

• I want to replace multiple occurences of whitespace inside the string with a single space
• ...and... I do not want whitespaces in the beginnin or end of the string (trim)

For this, I use code like this (the parenthesis on the first regexp are there just in order to make the code a bit more readable ... regexps can be a pain unless you are familiar with them):

s = s.replace(/^(\s*)|(\s*)$/g, '').replace(/\s+/g, ' ');

The reason this works is that the methods on String-object return a string object on which you can invoke another method (just like jQuery & some other libraries). Much more compact way to code if you want to execute multiple methods on a single object in succession.

Late reply, but adding that Mongoose also has the concept of Subdocuments

With this syntax, you should be able to reference your userSchema as a type in your postSchema like so:

var userSchema = new Schema({
    twittername: String,
    twitterID: Number,
    displayName: String,
    profilePic: String,
});

var postSchema = new Schema({
    name: String,
    postedBy: userSchema,
    dateCreated: Date,
    comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});

Note the updated postedBy field with type userSchema.

This will embed the user object within the post, saving an extra lookup required by using a reference. Sometimes this could be preferable, other times the ref/populate route might be the way to go. Depends on what your application is doing.

Because UTF-8 is multibyte and there is no char corresponding to your combination of \xe9 plus following space.

Why should it succeed in both utf-8 and latin-1?

Here how the same sentence should be in utf-8:

>>> o.decode('latin-1').encode("utf-8")
'a test of \xc3\xa9 char'

fields() and fieldNames() both were not working for me. And I had to spend quite sometime to find a way to iterate over the keys. There are two ways by which it can be done.

One is by converting it into a map (takes up more space):

ObjectMapper mapper = new ObjectMapper();
Map<String, Object> result = mapper.convertValue(jsonNode, Map.class);
for (String key : result.keySet())
{
    if(key.equals(foo))
    {
        //code here
    }
}

Another, by using a String iterator:

Iterator<String> it = jsonNode.getFieldNames();
while (it.hasNext())
{
    String key = it.next();
    if (key.equals(foo))
    {
         //code here
    }
}

Sometimes you need to remove the .lock file to get the service to run

The simplest way to add a column is to use "withColumn". Since the dataframe is created using sqlContext, you have to specify the schema or by default can be available in the dataset. If the schema is specified, the workload becomes tedious when changing every time.

Below is an example that you can consider:

from pyspark.sql import SQLContext
from pyspark.sql.types import *
sqlContext = SQLContext(sc) # SparkContext will be sc by default 

# Read the dataset of your choice (Already loaded with schema)
Data = sqlContext.read.csv("/path", header = True/False, schema = "infer", sep = "delimiter")

# For instance the data has 30 columns from col1, col2, ... col30. If you want to add a 31st column, you can do so by the following:
Data = Data.withColumn("col31", "Code goes here")

# Check the change 
Data.printSchema()

First make sure you have installed Nginx with the HTTP rewrite module. To install this we need to have pcre-library

How to install pcre library

If the above mentioned are done or if you already have them, then just add the below code in your nginx server block

  if ($host !~* ^www\.) {
    rewrite ^(.*)$ http://www.$host$1 permanent;
  }

To remove www from every request you can use

  if ($host = 'www.your_domain.com' ) {
   rewrite  ^/(.*)$  http://your_domain.com/$1  permanent;
  }

so your server block will look like

  server {
            listen       80;
            server_name  test.com;
            if ($host !~* ^www\.) {
                    rewrite ^(.*)$ http://www.$host$1 permanent;
            }
            client_max_body_size   10M;
            client_body_buffer_size   128k;

            root       /home/test/test/public;
            passenger_enabled on;
            rails_env production;

            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                    root   html;
            }
    }

You have two options to fix the issue:

1- Manually make sure the two versions match.
2- Use the IDE's help as follows:
- Right mouse click on the error in the 'Problems' view
- Select the 'Quick Fix' menu item from the pop-up menu
- Select the right compiler level in the provided dialog and click 'Finish'.

Taken from Eclipse: Java compiler level and project facet mismatch

Also gives location of where you can access the Java compiler and facet version.

var mouseX;
var mouseY;
$(document).mousemove( function(e) {
   mouseX = e.pageX; 
   mouseY = e.pageY;
});  
$(".classForHoverEffect").mouseover(function(){
  $('#DivToShow').css({'top':mouseY,'left':mouseX}).fadeIn('slow');
});

the function above will make the DIV appear over the link wherever that may be on the page. It will fade in slowly when the link is hovered. You could also use .hover() instead. From there the DIV will stay, so if you would like the DIV to disappear when the mouse moves away, then,

$(".classForHoverEffect").mouseout(function(){
  $('#DivToShow').fadeOut('slow');
});

If you DIV is already positioned, you can simply use

$('.classForHoverEffect').hover(function(){
  $('#DivToShow').fadeIn('slow');
});

Also, keep in mind, your DIV style needs to be set to display:none; in order for it to fadeIn or show.

Two steps works fine:

create table bu_x as (select a,b,c,d from x ) WITH no data;

insert into bu_x (a,b,c,d) select select a,b,c,d from x ;

Now only I came across this situation and found some more interesting features around GROUP_CONCAT. I hope these details will make you feel interesting.

Another use case could be something like OAuth, it's may not be called by the API directly, instead the callback URL will be called by the browser after completing the authencation with the identity provider.

Normally after end user key in the username password, the identity service provider will trigger a browser redirect to your "callback" url with the temporary authroization code, e.g.

https://example.com/callback?code=AUTHORIZATION_CODE

Then your application could use this authorization code to request a access token with the identity provider which has a much longer lifetime.

@PropertySource can be configured by factory argument. So you can do something like:

@PropertySource(value = "classpath:application-test.yml", factory = YamlPropertyLoaderFactory.class)

Where YamlPropertyLoaderFactory is your custom property loader:

public class YamlPropertyLoaderFactory extends DefaultPropertySourceFactory {
    @Override
    public PropertySource<?> createPropertySource(String name, EncodedResource resource) throws IOException {
        if (resource == null){
            return super.createPropertySource(name, resource);
        }

        return new YamlPropertySourceLoader().load(resource.getResource().getFilename(), resource.getResource(), null);
    }
}

Not jQuery, but it works well for a calendar with time: JavaScript Date Time Picker.

I just bound the click event to pop it up:

$(".arrival-date").click(function() {
    NewCssCal($(this).attr('id'), 'mmddyyyy', 'dropdown', true, 12);
});

GZip is simply deflate plus a checksum and header/footer. Deflate is faster, though, as I learned the hard way.

func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {

       let strString = ((textField.text)! as NSString).stringByReplacingCharactersInRange(range, withString: string)

 }

The Hibernate configuration file must define the entity classes:

<mapping class="annotations.Users"/>

Or you must explicitly add the class to the configuration using

configuration.addClass(annotations.Users.class)
// Read mappings as a application resourceName
 // addResource is for add hbml.xml files in case of declarative approach
configuration.addResource("myFile.hbm.xml");  // not hibernateAnnotations.cfg.xml

If you run into this problem with Visual Studio 2019 (VS2019), you can download the build tools from https://visualstudio.microsoft.com/downloads/. And, under Tools for Visual Studio 2019 and download Build Tools for Visual Studios 2019.

@ericholscher says on Twitter, "The one in the official docs.."

It's a great point, you should do what the docs say.

Quoted from the official pip installation instructions at http://www.pip-installer.org/en/latest/installing.html:

$ curl -O https://github.com/pypa/virtualenv/raw/master/virtualenv.py
$ python virtualenv.py my_new_env
$ . my_new_env/bin/activate
(my_new_env)$ pip install ...

is it still actual?

As I can see you wrote <target depends="build-subprojects,build-project" name="build"/>, then you wrote <target name="build-subprojects"/> (it does nothing). Could it be a reason? Does this <echo message="${ant.project.name}: ${ant.file}"/> print appropriate message? If no then target is not running. Take a look at the next link http://www.sqaforums.com/showflat.php?Number=623277

There's actually no direct way to get path to webdir in Symfony2 as the framework is completely independent of the webdir.

You can use getRootDir() on instance of kernel class, just as you write. If you consider renaming /web dir in future, you should make it configurable. For example AsseticBundle has such an option in its DI configuration (see here and here).

exit(int code); is declared in stdlib.h so you need an

#include <stdlib.h>

Also:
- You have no parameter for the exit(), it requires an int so provide one.
- Burn this book, it uses goto which is (for everyone but linux kernel hackers) bad, very, very, VERY bad.

Edit:
Oh, and

void main()

is bad, too, it's:

int main(int argc, char *argv[])

Also, this might help finding the actual location the btsnoop_hci.log is being saved:

adb shell "cat /etc/bluetooth/bt_stack.conf | grep FileName"

xDoc.LoadXML("<head><body><Inner> welcome </head> </Inner> <Outer> Bye</Outer>                    
                    </body></head>");

Binary strings store raw-byte data, whilst character strings store text. Use binary data when storing hexi-decimal values such as SID, GUID and so on. The uniqueidentifier data type contains a globally unique identifier, or GUID. This value is derived by using the NEWID() function to return a value that is unique to all objects. It's stored as a binary value but it is displayed as a character string.

Here is an example.

USE AdventureWorks2008R2;
GO
CREATE TABLE MyCcustomerTable
(
    user_login   varbinary(85) DEFAULT SUSER_SID()
    ,data_value   varbinary(1)
);
GO

INSERT MyCustomerTable (data_value)
    VALUES (0x4F);
GO

Applies to: SQL Server The following example creates the cust table with a uniqueidentifier data type, and uses NEWID to fill the table with a default value. In assigning the default value of NEWID(), each new and existing row has a unique value for the CustomerID column.

-- Creating a table using NEWID for uniqueidentifier data type.  
CREATE TABLE cust  
(  
 CustomerID uniqueidentifier NOT NULL  
   DEFAULT newid(),  
 Company varchar(30) NOT NULL,  
 ContactName varchar(60) NOT NULL,   
 Address varchar(30) NOT NULL,   
 City varchar(30) NOT NULL,  
 StateProvince varchar(10) NULL,  
 PostalCode varchar(10) NOT NULL,   
 CountryRegion varchar(20) NOT NULL,   
 Telephone varchar(15) NOT NULL,  
 Fax varchar(15) NULL  
);  
GO  
-- Inserting 5 rows into cust table.  
INSERT cust  
(CustomerID, Company, ContactName, Address, City, StateProvince,   
 PostalCode, CountryRegion, Telephone, Fax)  
VALUES  
 (NEWID(), 'Wartian Herkku', 'Pirkko Koskitalo', 'Torikatu 38', 'Oulu', NULL,  
 '90110', 'Finland', '981-443655', '981-443655')  
,(NEWID(), 'Wellington Importadora', 'Paula Parente', 'Rua do Mercado, 12', 'Resende', 'SP',  
 '08737-363', 'Brasil', '(14) 555-8122', '')

The model has a save method, which saves all the details necessary to reconstitute the model. An example from the keras documentation:

from keras.models import load_model

model.save('my_model.h5')  # creates a HDF5 file 'my_model.h5'
del model  # deletes the existing model

# returns a compiled model
# identical to the previous one
model = load_model('my_model.h5')

Add one unique session or cookie in button click event then redirect page on same URL using Request.RawUrl Now add code in Page_Load event to grab that session or coockie. If session/cookie matches then you can knows that page redirected using refresh button. So decrease hit counter by 1 to keep it on same number do hitcountr -= hitconter

Else increase the hit counter.

You do want to add App.config to your tests class library, if you're using a tracer/logger. Otherwise nothing gets logged when you run the test through a test runner such as TestDriven.Net.

For example, I use TraceSource in my programs, but running tests doesn't log anything unless I add an App.config file with the trace/log configuration to the test class library too.

Otherwise, adding App.config to a class library doesn't do anything.

If you need a free and simple API for converting one currency to another, try free.currencyconverterapi.com.

Disclaimer, I'm the author of the website and I use it for one of my other websites.

The service is free to use even for commercial applications but offers no warranty. For performance reasons, the values are only updated every hour.

A sample conversion URL is: http://free.currencyconverterapi.com/api/v6/convert?q=EUR_PHP&compact=ultra&apiKey=sample-api-key which will return a json-formatted value, e.g. {"EUR_PHP":60.849184}

I use Ext, so I ended up doing this:

var theForm = Ext.get("theform");
var inputButtons = Ext.DomQuery.jsSelect('input[type="submit"]', theForm.dom);
var inputButtonPressed = null;
for (var i = 0; i < inputButtons.length; i++) {
    Ext.fly(inputButtons[i]).on('click', function() {
        inputButtonPressed = this;
    }, inputButtons[i]);
}

and then when it was time submit I did

if (inputButtonPressed !== null) inputButtonPressed.click();
else theForm.dom.submit();

Wait, you say. This will loop if you're not careful. So, onSubmit must sometimes return true

// Notice I'm not using Ext here, because they can't stop the submit
theForm.dom.onsubmit = function () {
    if (gottaDoSomething) {
        // Do something asynchronous, call the two lines above when done.
        gottaDoSomething = false;
        return false;
    }
    return true;
}

In Tensorflow 2.0+ (or in Eager mode environment) you can call .numpy() method:

import tensorflow as tf

matrix1 = tf.constant([[3., 3.0]])
matrix2 = tf.constant([[2.0],[2.0]])
product = tf.matmul(matrix1, matrix2)

print(product.numpy()) 

You can get this error if you define a project as an .exe but intent to create a .lib or a .dll

I found that the first solution in the accepted answer to be problematic for cases where the newline character is still required. The easiest solution to the problem was doing this:

numpy.savetxt(filename, [a], delimiter='\t')

Might benefit you to be aware of another option, word-wrap: break-word;

The difference here is that words that can completely fit on 1 line will do that, vs. being forced to break simply because there is no more real estate on the line the word starts on.

See the fiddle for an illustration http://jsfiddle.net/Jqkcp/

Here is a pretty simple stored procedure that does the trick as well...

    CREATE PROCEDURE GetBCPTable
    @table_name varchar(200)
AS
BEGIN
    DECLARE @raw_sql nvarchar(3000)

    DECLARE @columnHeader VARCHAR(8000)
    SELECT @columnHeader = COALESCE(@columnHeader+',' ,'')+ ''''+column_name +'''' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @table_name

    DECLARE @ColumnList VARCHAR(8000)
    SELECT @ColumnList = COALESCE(@ColumnList+',' ,'')+ 'CAST('+column_name +' AS VARCHAR)' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @table_name

    SELECT @raw_sql = 'SELECT '+ @columnHeader +' UNION ALL SELECT ' + @ColumnList + ' FROM ' + @table_name
    --PRINT @raw_SQL
    EXECUTE sp_executesql  @raw_sql
END
GO

I would consider using the attr_defaults found here. Your wildest dreams will come true.

For split string by space like in Python lang, can be used:

   var w = "hello    my brothers    ;";
   w.split(/(\s+)/).filter( function(e) { return e.trim().length > 0; } );

output:

   ["hello", "my", "brothers", ";"]

or similar:

   w.split(/(\s+)/).filter( e => e.trim().length > 0)

(output some)

// C++11. 
std::string index_html=R"html(
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>VIPSDK MONITOR</title>
    <meta http-equiv="refresh" content="10">
</head>
<style type="text/css">
</style>
</html>
)html";

There's several things that all need to be in place. Just to summarize them all in one location:

Set the following option:

:filetype indent on
:set filetype=html           # abbrev -  :set ft=html
:set smartindent             # abbrev -  :set si

Then either move the cursor to the top of the file and indent to the end: gg =G
Or select the desired text to indent and hit = to indent it.

For a <br> on each line, use

<textarea wrap="physical"></textarea>

You will get \ns in the value of the textarea. Then, use the nl2br() function to create <br>s, or you can explode() it for <br> or \n.

Hope this helps

You can specify an empty string as an argument to join, if no argument is specified a comma is used.

 arr.join('');

I have a more general answer; but I believe it is useful for counting the columns for all tables in a DB:

SELECT table_name, count(*)
FROM information_schema.columns
GROUP BY table_name;

You will need to install the Apple Developer Tools. Once you have done that, the easiest thing is to either use the Xcode IDE or use gcc, or nowadays better cc (the clang LLVM compiler), from the command line.

According to Apple's site, the latest version of Xcode (3.2.1) only runs on Snow Leopard (10.6) so if you have an earlier version of OS X you will need to use an older version of Xcode. Your Mac should have come with a Developer Tools DVD which will contain a version that should run on your system. Also, the Apple Developer Tools site still has older versions available for download. Xcode 3.1.4 should run on Leopard (10.5).

You could use a "variable" inside the output filename, for example:

/tmp/FetchBlock-${current_date}.txt

current_date:

Returns the current system time formatted as yyyyMMdd_HHmm. An optional argument can be used to provide alternative formatting. The argument must be valid pattern for java.util.SimpleDateFormat.

Or you can also use a system_property or an env_var to specify something dynamic (either one needs to be specified as arguments)

The following example is from the Code Project article, (Almost) Everything In Active Directory via C#:

// userDn is a Distinguished Name such as:
// "LDAP://CN=Joe Smith,OU=Sales,OU=domain,OU=com"
public ArrayList Groups(string userDn, bool recursive)
{
    ArrayList groupMemberships = new ArrayList();
    return AttributeValuesMultiString("memberOf", userDn,
        groupMemberships, recursive);
}

public ArrayList AttributeValuesMultiString(string attributeName,
     string objectDn, ArrayList valuesCollection, bool recursive)
{
    DirectoryEntry ent = new DirectoryEntry(objectDn);
    PropertyValueCollection ValueCollection = ent.Properties[attributeName];
    IEnumerator en = ValueCollection.GetEnumerator();

    while (en.MoveNext())
    {
        if (en.Current != null)
        {
            if (!valuesCollection.Contains(en.Current.ToString()))
            {
                valuesCollection.Add(en.Current.ToString());
                if (recursive)
                {
                    AttributeValuesMultiString(attributeName, "LDAP://" +
                    en.Current.ToString(), valuesCollection, true);
                }
            }
        }
    }
    ent.Close();
    ent.Dispose();
    return valuesCollection;
}

Just call the Groups method with the Distinguished Name for the user, and pass in the bool flag to indicate if you want to include nested / child groups memberships in your resulting ArrayList:

ArrayList groups = Groups("LDAP://CN=Joe Smith,OU=Sales,OU=domain,OU=com", true);
foreach (string groupName in groups)
{
    Console.WriteLine(groupName);
}

If you need to do any serious level of Active Directory programming in .NET I highly recommend bookmarking & reviewing the Code Project article I mentioned above.

You can't return because you're not in a function. You can exit though.

import sys
sys.exit(0)

0 (the default) means success, non-zero means failure.

I solved this issue following the indication provided in the article http://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/ with little changes.

SSLContext context = SSLContext.getInstance("TLS");
context.init(null, null, null);
SSLSocketFactory noSSLv3Factory = null;
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
    noSSLv3Factory = new TLSSocketFactory(sslContext.getSocketFactory());
} else {
    noSSLv3Factory = sslContext.getSocketFactory();
}
connection.setSSLSocketFactory(noSSLv3Factory);

This is the code of the custom TLSSocketFactory:

public static class TLSSocketFactory extends SSLSocketFactory {

    private SSLSocketFactory internalSSLSocketFactory;

    public TLSSocketFactory(SSLSocketFactory delegate) throws KeyManagementException, NoSuchAlgorithmException {
        internalSSLSocketFactory = delegate;
    }

    @Override
    public String[] getDefaultCipherSuites() {
        return internalSSLSocketFactory.getDefaultCipherSuites();
    }

    @Override
    public String[] getSupportedCipherSuites() {
        return internalSSLSocketFactory.getSupportedCipherSuites();
    }

    @Override
    public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
    }

    @Override
    public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
    }

    @Override
    public Socket createSocket(InetAddress host, int port) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
    }

    /*
     * Utility methods
     */

    private static Socket enableTLSOnSocket(Socket socket) {
        if (socket != null && (socket instanceof SSLSocket)
                && isTLSServerEnabled((SSLSocket) socket)) { // skip the fix if server doesn't provide there TLS version
            ((SSLSocket) socket).setEnabledProtocols(new String[]{TLS_v1_1, TLS_v1_2});
        }
        return socket;
    }

    private static boolean isTLSServerEnabled(SSLSocket sslSocket) {
        System.out.println("__prova__ :: " + sslSocket.getSupportedProtocols().toString());
        for (String protocol : sslSocket.getSupportedProtocols()) {
            if (protocol.equals(TLS_v1_1) || protocol.equals(TLS_v1_2)) {
                return true;
            }
        }
        return false;
    }
}

Edit: Thank's to ademar111190 for the kotlin implementation (link)

class TLSSocketFactory constructor(
        private val internalSSLSocketFactory: SSLSocketFactory
) : SSLSocketFactory() {

    private val protocols = arrayOf("TLSv1.2", "TLSv1.1")

    override fun getDefaultCipherSuites(): Array<String> = internalSSLSocketFactory.defaultCipherSuites

    override fun getSupportedCipherSuites(): Array<String> = internalSSLSocketFactory.supportedCipherSuites

    override fun createSocket(s: Socket, host: String, port: Int, autoClose: Boolean) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose))

    override fun createSocket(host: String, port: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port))

    override fun createSocket(host: String, port: Int, localHost: InetAddress, localPort: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort))

    override fun createSocket(host: InetAddress, port: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port))

    override fun createSocket(address: InetAddress, port: Int, localAddress: InetAddress, localPort: Int) =
            enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort))

    private fun enableTLSOnSocket(socket: Socket?) = socket?.apply {
        if (this is SSLSocket && isTLSServerEnabled(this)) {
            enabledProtocols = protocols
        }
    }

    private fun isTLSServerEnabled(sslSocket: SSLSocket) = sslSocket.supportedProtocols.any { it in protocols }

}

Access-Engine does not support

SELECT count(DISTINCT....) FROM ...

You have to do it like this:

SELECT count(*) 
FROM
(SELECT DISTINCT Name FROM table1)

Its a little workaround... you're counting a DISTINCT selection.

I was able to fix this problem by setting font-size: 0 .

The toString is supposed to return a String.

public String toString() { 
    return "Name: '" + this.name + "', Height: '" + this.height + "', Birthday: '" + this.bDay + "'";
} 

I suggest you make use of your IDE's features to generate the toString method. Don't hand-code it.

For instance, Eclipse can do so if you simply right-click on the source code and select Source > Generate toString

Easiest way would be to use join like this:

>>> myTuple = ['h','e','l','l','o']
>>> ''.join(myTuple)
'hello'

This works because your delimiter is essentially nothing, not even a blank space: ''.

To start a new session

screen -S your_session_name

To rename an existing session

Ctrl+a, : sessionname YOUR_SESSION_NAME Enter

You must be inside the session

in this thread i found my answer.

1. I went to google console,
2. generate a new project, made refresh, because in my case after create the page didn't reload
3. select new project
4. create a client ID
5. use it for what you need

thanks guys :D

I have written the following code in my last assignment, it may help you:

// A method that converts the nano-seconds to Seconds-Minutes-Hours form
private static String formatTime(long nanoSeconds)
{
    int hours, minutes, remainder, totalSecondsNoFraction;
    double totalSeconds, seconds;


    // Calculating hours, minutes and seconds
    totalSeconds = (double) nanoSeconds / 1000000000.0;
    String s = Double.toString(totalSeconds);
    String [] arr = s.split("\\.");
    totalSecondsNoFraction = Integer.parseInt(arr[0]);
    hours = totalSecondsNoFraction / 3600;
    remainder = totalSecondsNoFraction % 3600;
    minutes = remainder / 60;
    seconds = remainder % 60;
    if(arr[1].contains("E")) seconds = Double.parseDouble("." + arr[1]);
    else seconds += Double.parseDouble("." + arr[1]);


    // Formatting the string that conatins hours, minutes and seconds
    StringBuilder result = new StringBuilder(".");
    String sep = "", nextSep = " and ";
    if(seconds > 0)
    {
        result.insert(0, " seconds").insert(0, seconds);
        sep = nextSep;
        nextSep = ", ";
    }
    if(minutes > 0)
    {
        if(minutes > 1) result.insert(0, sep).insert(0, " minutes").insert(0, minutes);
        else result.insert(0, sep).insert(0, " minute").insert(0, minutes);
        sep = nextSep;
        nextSep = ", ";
    }
    if(hours > 0)
    {
        if(hours > 1) result.insert(0, sep).insert(0, " hours").insert(0, hours);
        else result.insert(0, sep).insert(0, " hour").insert(0, hours);
    }
    return result.toString();
}

Just convert nano-seconds to milli-seconds.

There's another very simple answer which can work for some simple graphs.

Just add a call to guide_legend() into your graph.

ggplot(...) + ... + guide_legend(title="my awesome title")

As shown in the very nice ggplot docs.

If that doesn't work, you can more precisely set your guide parameters with a call to guides:

ggplot(...) + ... + guides(fill=guide_legend("my awesome title"))

You can also vary the shape/color/size by specifying these parameters for your call to guides as well.

try this single command to both delete and insert the data:

DELETE MyTable
    OUTPUT DELETED.Col1, DELETED.COl2,...
        INTO MyBackupTable

working sample:

--set up the tables
DECLARE @MyTable table (col1 int, col2 varchar(5))
DECLARE @MyBackupTable table (col1 int, col2 varchar(5))
INSERT INTO @MyTable VALUES (1,'A')
INSERT INTO @MyTable VALUES (2,'B')
INSERT INTO @MyTable VALUES (3,'C')
INSERT INTO @MyTable VALUES (4,'D')

--single command that does the delete and inserts
DELETE @MyTable
    OUTPUT DELETED.Col1, DELETED.COl2
        INTO @MyBackupTable

--show both tables final values
select * from @MyTable
select * from @MyBackupTable

OUTPUT:

(1 row(s) affected)

(1 row(s) affected)

(1 row(s) affected)

(1 row(s) affected)

(4 row(s) affected)
col1        col2
----------- -----

(0 row(s) affected)

col1        col2
----------- -----
1           A
2           B
3           C

int min and max values

Int -2,147,483,648 / 2,147,483,647 Int 64 -9,223,372,036,854,775,808 / 9,223,372,036,854,775,807

i guess you could set a to equal 9,223,372,036,854,775,807 but it would need to be an int64

if you always want a to be grater that b why do you need to check it? just set it to be true always

I also had similar problems when trying to link static compiled fontconfig and expat into a linux shared object:

/opt/rh/devtoolset-7/root/usr/libexec/gcc/x86_64-redhat-linux/7/ld: /3rdparty/fontconfig/lib/linux-x86_64/libfontconfig.a(fccfg.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
/opt/rh/devtoolset-7/root/usr/libexec/gcc/x86_64-redhat-linux/7/ld: /3rdparty/expat/lib/linux-x86_64/libexpat.a(xmlparse.o): relocation R_X86_64_PC32 against symbol `stderr@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC
[...]

This contrary to the fact that I was already passing -fPIC flags though CFLAGS variable, and other compilers/linkers variants (clang/lld) were perfectly working with the same build configuration. It ended up that these dependencies control position-independent code settings through despicable autoconf scripts and need --with-pic switch during build configuration on linux gcc/ld combination, and its lack probably overrides same the setting in CFLAGS. Pass the switch to configure script and the dependencies will be correctly compiled with -fPIC.

Well /etc/crontab just an ascii file so the simplest is to just

 echo "*/15 * * * *   root     date" >> /etc/crontab

which will add a job which will email you every 15 mins. Adjust to taste, and test via grep or other means whether the line was already added to make your script idempotent.

On Ubuntu et al, you can also drop files in /etc/cron.* which is easier to do and test for---plus you don't mess with (system) config files such as /etc/crontab.

Another way.

try (BufferedReader reader = Files.newBufferedReader(
        Paths.get("file.txt"), StandardCharsets.UTF_8)) {
    List<String> line = reader.lines()
                              .skip(31)
                              .limit(1)
                              .collect(Collectors.toList());

    line.stream().forEach(System.out::println);
}

I've had the same problem, our work environment is based on Eclipse Java projects, and we needed to build automatically an ANT file so that we could use a continuous integration server (Jenkins, in our case).

We rolled out our own Eclipse Java to Ant tool, which is now available on GitHub:

ant-build-for-java

To use it, call:

java -jar ant-build-for-java.jar <folder with repositories> [<.userlibraries file>]

The first argument is the folder with the repositories. It will search the folder recursively for any .project file. The tool will create a build.xml in the given folder.

Optionally, the second argument can be an exported .userlibraries file, from Eclipse, needed when any of the projects use Eclipse user libraries. The tool was tested only with user libraries using relative paths, it's how we use them in our repo. This implies that JARs and other archives needed by projects are inside an Eclipse project, and referenced from there.

The tool only supports dependencies from other Eclipse projects and from Eclipse user libraries.

I remember one time when I stumbled upon this issue a few years ago, it's because windows don't have readline, therefore no interactive shell, to use php interactive mode without readline support, you can do this instead:

C:\>php -a 
Interactive mode enabled 

<?php 
echo "Hello, world!"; 
?> 
^Z 
Hello, world!

After entering interactive mode, type using opening (<?php) and closing (?>) php tag, and end with control Z (^Z) which denotes the end of file.

I also recall that I found the solution from php's site user comment: http://www.php.net/manual/en/features.commandline.interactive.php#105729

As everyone has said, you definitely need the key. There's no workaround for that. However, you might be surprised at how good the data recovery software can be, and how long the key may linger on your systems -- it's a tiny, tiny file, after all, and may not yet be overwritten. I was pleasantly surprised on both counts.

I develop on an OSX machine. I unintentionally deleted my app key around 6 weeks ago. When I tried to update, I realized my schoolboy error. I tried all the recovery tools I could find for OSX, but none could find the file -- not because it wasn't there, but because these tools are optimized to find the sorts of files the majority of users want back (photos, Word docs, etc.). They're definitely not looking for a 1KB file with an unusual file signature.

Now this next part is going to sound like a plug, but it isn't -- I don't have any connection to the developers:

The only recover tool I found that worked was one called Data Rescue by Prosoft Engineering (which I believe works for other files systems as well -- not just HFS+). It worked because it has a feature which allows you to train it to look for any file type -- even an Android key. You give it several examples. (I generated a few keys, filling in the data fields in as like manner as possible to the original). You then tell it to "deep search". If you're lucky, you'll get your key back in the "custom files" section.

For me, it was a life saver.

It's $100 to purchase, so it's not cheap, but it's worth it if you've got a mass of users and no further means of feeding them updates.

I believe they allow you 1 free file recovery in demo mode, but, unfortunately, in my case, I had several keys and could not tell which one was the one I needed without recovering them all (file names are not preserved on HFS+).

Try it first in demo mode, you may get lucky and be able to recover the key without paying anything.

May this message help someone. It's a sickening feeling, I know, but there may be relief.

For me the solution was besides using "Ntlm" as credential type:

    XxxSoapClient xxxClient = new XxxSoapClient();
    ApplyCredentials(userName, password, xxxClient.ClientCredentials);

    private static void ApplyCredentials(string userName, string password, ClientCredentials clientCredentials)
    {
        clientCredentials.UserName.UserName = userName;
        clientCredentials.UserName.Password = password;
        clientCredentials.Windows.ClientCredential.UserName = userName;
        clientCredentials.Windows.ClientCredential.Password = password;
        clientCredentials.Windows.AllowNtlm = true;
        clientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
    }  

* Very Easy Solution:

1. Go to IIS

2. Select your application from left Pane.

3. Double click on Directory Browsing in middle Pane.

4. Now go to right pane and under Action tab, Just click 'ENABLE'

That's all !!

People, try to understand the error: Config Error Cannot read configuration file due to insufficient permissions

You might not be able to change npm registry using .bat file as Gntem pointed out. But I understand that you need the ability to automate changing registries. You can do so by having your .npmrc configs in separate files (say npmrc_jfrog & npmrc_default) and have your .bat files do the copying task.

For example (in Windows): Your default_registry.bat will have

xcopy /y npmrc_default .npmrc

and your jfrog_registry.bat will have

xcopy /y npmrc_jfrog .npmrc

Note: /y suppresses prompting to confirm that you want to overwrite an existing destination file.

This will make sure that all the config properties (registry, proxy, apiKeys, etc.) get copied over to .npmrc.

You can read more about xcopy here.

While the marked answer gets it working, all you really need to add to the webconfig is:

    <handlers>
      <!-- Your other remove tags-->
      <remove name="UrlRoutingModule-4.0"/>
      <!-- Your other add tags-->
      <add name="UrlRoutingModule-4.0" path="*" verb="*" type="System.Web.Routing.UrlRoutingModule" preCondition=""/>
    </handlers>

Note that none of those have a particular order, though you want your removes before your adds.

The reason that we end up getting a 404 is because the Url Routing Module only kicks in for the root of the website in IIS. By adding the module to this application's config, we're having the module to run under this application's path (your subdirectory path), and the routing module kicks in.

In ASP.net WebApi, the simplest way to pass-in a header on Swagger UI is to implement the Apply(...) method on the IOperationFilter interface.

Add this to your project:

public class AddRequiredHeaderParameter : IOperationFilter
{
    public void Apply(Operation operation, SchemaRegistry schemaRegistry, ApiDescription apiDescription)
    {
        if (operation.parameters == null)
            operation.parameters = new List<Parameter>();

        operation.parameters.Add(new Parameter
        {
            name = "MyHeaderField",
            @in = "header",
            type = "string",
            description = "My header field",
            required = true
        });
    }
}

In SwaggerConfig.cs, register the filter from above using c.OperationFilter<>():

public static void Register()
{
    var thisAssembly = typeof(SwaggerConfig).Assembly;

    GlobalConfiguration.Configuration 
        .EnableSwagger(c =>
        {
            c.SingleApiVersion("v1", "YourProjectName");
            c.IgnoreObsoleteActions();
            c.UseFullTypeNameInSchemaIds();
            c.DescribeAllEnumsAsStrings();
            c.IncludeXmlComments(GetXmlCommentsPath());
            c.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());


            c.OperationFilter<AddRequiredHeaderParameter>(); // Add this here
        })
        .EnableSwaggerUi(c =>
        {
            c.DocExpansion(DocExpansion.List);
        });
}

You can use ng-repeat with option like this:

<form>
    <select ng-model="yourSelect" 
        ng-options="option as option for option in ['var1', 'var2', 'var3']"
        ng-init="yourSelect='var1'"></select>
    <input type="hidden" name="yourSelect" value="{{yourSelect}}" />
</form>

When you submit your form you can get value of input hidden.

When you send bytes from a buffer with a normal TCP socket, the send function returns the number of bytes of the buffer that were sent. If it is a non-blocking socket or a non-blocking send then the number of bytes sent may be less than the size of the buffer. If it is a blocking socket or blocking send, then the number returned will match the size of the buffer but the call may block. With WebSockets, the data that is passed to the send method is always either sent as a whole "message" or not at all. Also, browser WebSocket implementations do not block on the send call.

But there are more important differences on the receiving side of things. When the receiver does a recv (or read) on a TCP socket, there is no guarantee that the number of bytes returned corresponds to a single send (or write) on the sender side. It might be the same, it may be less (or zero) and it might even be more (in which case bytes from multiple send/writes are received). With WebSockets, the recipient of a message is event-driven (you generally register a message handler routine), and the data in the event is always the entire message that the other side sent.

Note that you can do message based communication using TCP sockets, but you need some extra layer/encapsulation that is adding framing/message boundary data to the messages so that the original messages can be re-assembled from the pieces. In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message. The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message.

What about the ansicolors library? You can simple do:

from colors import color, red, blue

# common colors
print(red('This is red'))
print(blue('This is blue'))

# colors by name or code
print(color('Print colors by name or code', 'white', '#8a2be2'))

#change-avatar-file is a file input #change-avatar-file is a img tag (the target of jcrop) The "key" is FR.onloadend Event https://developer.mozilla.org/en-US/docs/Web/API/FileReader

$('#change-avatar-file').change(function(){
        var currentImg;
        if ( this.files && this.files[0] ) {
            var FR= new FileReader();
            FR.onload = function(e) {
                $('#avatar-change-img').attr( "src", e.target.result );
                currentImg = e.target.result;
            };
            FR.readAsDataURL( this.files[0] );
            FR.onloadend = function(e){
                //console.log( $('#avatar-change-img').attr( "src"));
                var jcrop_api;

                $('#avatar-change-img').Jcrop({
                    bgFade:     true,
                    bgOpacity: .2,
                    setSelect: [ 60, 70, 540, 330 ]
                },function(){
                    jcrop_api = this;
                });
            }
        }
    });

In Sql the with statement specifies a temporary named result set, known as a common table expression (CTE). It can be used for recursive queries, but in this case, it specifies as subset. If mysql allows for subselectes i would try

select t1.* 
from  (
            SELECT  article.*, 
                    userinfo.*, 
                    category.* 
            FROM    question INNER JOIN 
                    userinfo ON userinfo.user_userid=article.article_ownerid INNER JOIN category ON article.article_categoryid=category.catid
            WHERE   article.article_isdeleted = 0
     ) t1
ORDER BY t1.article_date DESC Limit 1, 3

exec sp_lock

This query should give you existing locks.

exec sp_who SPID -- will give you some info

Having spids, you could check activity monitor(processes tab) to find out what processes are locking the tables ("details" for more info and "kill process" to kill it).

The h1 tags unfortunately do not receive the onmouseout events.

The simple Javascript snippet below will work for all elements and uses only 1 mouse event.

Note: "The borders in the snippet are applied to provide a visual demarcation of the elements."

document.body.onmousemove = function(){ move("The dog is in its shed"); };_x000D_
_x000D_
document.body.style.border = "2px solid red";_x000D_
document.getElementById("h1Tag").style.border = "2px solid blue";_x000D_
_x000D_
function move(what) {_x000D_
    if(event.target.id == "h1Tag"){ document.getElementById("goy").innerHTML = "what"; } else { document.getElementById("goy").innerHTML = ""; }_x000D_
}

<h1 id="h1Tag">lalala</h1>_x000D_
<div id="goy"></div>

This can also be done in pure CSS by adding the hover selector css property to the h1 tag.

adjust his code:

Object.prototype.each = function(iterateFunc) {
        var counter = 0,
keys = Object.keys(this),
currentKey,
len = keys.length;
        var that = this;
        var next = function() {

            if (counter < len) {
                currentKey = keys[counter++];
                iterateFunc(currentKey, that[currentKey]);

                next();
            } else {
                that = counter = keys = currentKey = len = next = undefined;
            }
        };
        next();
    };

    ({ property1: 'sdsfs', property2: 'chat' }).each(function(key, val) {
        // do things
        console.log(key);
    });

just a simple class that benchmark the codeblock :

using namespace std::chrono;

class benchmark {
  public:
  time_point<high_resolution_clock>  t0, t1;
  unsigned int *d;
  benchmark(unsigned int *res) : d(res) { 
                 t0 = high_resolution_clock::now();
  }
  ~benchmark() { t1 = high_resolution_clock::now();
                  milliseconds dur = duration_cast<milliseconds>(t1 - t0);
                  *d = dur.count();
  }
};
// simple usage 
// unsigned int t;
// { // put the code in a block
//  benchmark bench(&t);
//  // ...
//  // code to benchmark
// }
// HERE the t contains time in milliseconds

// one way to use it can be :
#define BENCH(TITLE,CODEBLOCK) \
  unsigned int __time__##__LINE__ = 0;  \
  { benchmark bench(&__time__##__LINE__); \
      CODEBLOCK \
  } \
  printf("%s took %d ms\n",(TITLE),__time__##__LINE__);


int main(void) {
  BENCH("TITLE",{
    for(int n = 0; n < testcount; n++ )
      int a = n % 3;
  });
  return 0;
}

When connecting to Mysql remotely, I got the error. I had this warning in /var/log/mysqld.log:

[Warning] IP address 'X.X.X.X' could not be resolved: Temporary failure in name resolution

I just added this line to /etc/hosts file:

X.X.X.X some_name

Problem solved! Not using skip-name-resolve caused some errors in my local app when connecting to MySQL.

exit is a helper for the interactive shell - sys.exit is intended for use in programs.

The site module (which is imported automatically during startup, except if the -S command-line option is given) adds several constants to the built-in namespace (e.g. exit). They are useful for the interactive interpreter shell and should not be used in programs.

Technically, they do mostly the same: raising SystemExit. sys.exit does so in sysmodule.c:

static PyObject *
sys_exit(PyObject *self, PyObject *args)
{
    PyObject *exit_code = 0;
    if (!PyArg_UnpackTuple(args, "exit", 0, 1, &exit_code))
        return NULL;
    /* Raise SystemExit so callers may catch it or clean up. */
    PyErr_SetObject(PyExc_SystemExit, exit_code);
   return NULL;
}

While exit is defined in site.py and _sitebuiltins.py, respectively.

class Quitter(object):
    def __init__(self, name):
        self.name = name
    def __repr__(self):
        return 'Use %s() or %s to exit' % (self.name, eof)
    def __call__(self, code=None):
        # Shells like IDLE catch the SystemExit, but listen when their
        # stdin wrapper is closed.
        try:
            sys.stdin.close()
        except:
            pass
        raise SystemExit(code)
__builtin__.quit = Quitter('quit')
__builtin__.exit = Quitter('exit')

Note that there is a third exit option, namely os._exit, which exits without calling cleanup handlers, flushing stdio buffers, etc. (and which should normally only be used in the child process after a fork()).

Please note there's also git reset --soft HEAD^. It's similar to git reset (which defaults to --mixed) but it retains the index contents. So that if you've added/removed files, you have them in the index already.

Turns out to be very useful in case of giant commits.

The following are tried, tested and proven methods to check if a row exists.

(Some of which I use myself, or have used in the past).

Edit: I made an previous error in my syntax where I used mysqli_query() twice. Please consult the revision(s).

I.e.:

if (!mysqli_query($con,$query)) which should have simply read as if (!$query).

• I apologize for overlooking that mistake.

Side note: Both '".$var."' and '$var' do the same thing. You can use either one, both are valid syntax.

Here are the two edited queries:

$query = mysqli_query($con, "SELECT * FROM emails WHERE email='".$email."'");

    if (!$query)
    {
        die('Error: ' . mysqli_error($con));
    }

if(mysqli_num_rows($query) > 0){

    echo "email already exists";

}else{

    // do something

}

and in your case:

$query = mysqli_query($dbl, "SELECT * FROM `tblUser` WHERE email='".$email."'");

    if (!$query)
    {
        die('Error: ' . mysqli_error($dbl));
    }

if(mysqli_num_rows($query) > 0){

    echo "email already exists";

}else{

    // do something

}

You can also use mysqli_ with a prepared statement method:

$query = "SELECT `email` FROM `tblUser` WHERE email=?";

if ($stmt = $dbl->prepare($query)){

        $stmt->bind_param("s", $email);

        if($stmt->execute()){
            $stmt->store_result();

            $email_check= "";         
            $stmt->bind_result($email_check);
            $stmt->fetch();

            if ($stmt->num_rows == 1){

            echo "That Email already exists.";
            exit;

            }
        }
    }

Or a PDO method with a prepared statement:

<?php
$email = $_POST['email'];

$mysql_hostname = 'xxx';
$mysql_username = 'xxx';
$mysql_password = 'xxx';
$mysql_dbname = 'xxx';

try {
$conn= new PDO("mysql:host=$mysql_hostname;dbname=$mysql_dbname", $mysql_username, $mysql_password); 
     $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
     exit( $e->getMessage() );
}

// assuming a named submit button
if(isset($_POST['submit']))
    {

        try {
            $stmt = $conn->prepare('SELECT `email` FROM `tblUser` WHERE email = ?');
            $stmt->bindParam(1, $_POST['email']); 
            $stmt->execute();
            while($row = $stmt->fetch(PDO::FETCH_ASSOC)) {

            }
        }
        catch(PDOException $e) {
            echo 'ERROR: ' . $e->getMessage();
        }

    if($stmt->rowCount() > 0){
        echo "The record exists!";
    } else {
        echo "The record is non-existant.";
    }


    }
?>

• Prepared statements are best to be used to help protect against an SQL injection.

N.B.:

When dealing with forms and POST arrays as used/outlined above, make sure that the POST arrays contain values, that a POST method is used for the form and matching named attributes for the inputs.

• FYI: Forms default to a GET method if not explicity instructed.

Note: <input type = "text" name = "var"> - $_POST['var'] match. $_POST['Var'] no match.

• POST arrays are case-sensitive.

Please note that MySQL APIs do not intermix, in case you may be visiting this Q&A and you're using mysql_ to connect with (and querying with).

• You must use the same one from connecting to querying.

Consult the following about this:

• Can I mix MySQL APIs in PHP?

If you are using the mysql_ API and have no choice to work with it, then consult the following Q&A on Stack:

• MySql php: check if Row exists

The mysql_* functions are deprecated and will be removed from future PHP releases.

• It's time to step into the 21st century.

You can also add a UNIQUE constraint to (a) row(s).

I am having OpenCV version 3.4.3 on MacOS. I was getting the same error as above.

I changed my code from

frame = cv2.resize(frame, (0,0), fx=0.5, fy=0.5)   

to

frame = cv2.resize(frame, None, fx=0.5, fy=0.5)    

Now its working fine for me.

I use this script in bash:

#!/bin/bash

now=$(date +"%b%d-%Y-%H%M%S")
FILE="$1"
name="${FILE%.*}"
ext="${FILE##*.}"

cp -v $FILE $name-$now.$ext

This script copies filename.ext to filename-date.ext, there is another that moves filename.ext to filename-date.ext, you can download them from here. Hope you find them useful!!

$(document).bind('contextmenu', function(e) {
    e.stopPropagation();
    e.preventDefault();
    e.stopImmediatePropagation();
    return false;
});

to enable it again:

$(document).unbind('click');
$(document).unbind('contextmenu');

First redirect stderr to stdout — the pipe; then redirect stdout to /dev/null (without changing where stderr is going):

command 2>&1 >/dev/null | grep 'something'

For the details of I/O redirection in all its variety, see the chapter on Redirections in the Bash reference manual.

Note that the sequence of I/O redirections is interpreted left-to-right, but pipes are set up before the I/O redirections are interpreted. File descriptors such as 1 and 2 are references to open file descriptions. The operation 2>&1 makes file descriptor 2 aka stderr refer to the same open file description as file descriptor 1 aka stdout is currently referring to (see dup2() and open()). The operation >/dev/null then changes file descriptor 1 so that it refers to an open file description for /dev/null, but that doesn't change the fact that file descriptor 2 refers to the open file description which file descriptor 1 was originally pointing to — namely, the pipe.

After generating ctags, you can also use the following in vim:

:tag <f_name>

Above will take you to function definition.

I ran into this problem where the one liner provided by the first answer worked well. However, I had the extra complication where the second copy of the column had all of the data. The first copy did not.

The solution was to create two data frames by splitting the one data frame by toggling the negation operator. Once I had the two data frames, I ran a join statement using the lsuffix. This way, I could then reference and delete the column without the data.

you will need to specify which branch and which remote when pushing:

? git init ./
? git add Readme.md
? git commit -m "Initial Commit"
? git remote add github <project url>
? git push github master

Will work as expected.

You can set this up by default by doing:

? git branch -u github/master master

which will allow you to do a git push from master without specifying the remote or branch.

In Excel, there is a way to embed relative reference to file or directory. You can try type in excel cell : =HYPERLINK("..\Name_of_file_or_folder\","DisplayLinkName")

You didn't do what you're being asked to do.

What is asked:

I have to execute ../gradlew build

What you do

cd ..
gradlew build

That's not the same thing.

The first one will use the gradlew command found in the .. directory (mdeinum...), and look for the build file to execute in the current directory, which is (for example) chapter1-bookstore.

The second one will execute the gradlew command found in the current directory (mdeinum...), and look for the build file to execute in the current directory, which is mdeinum....

So the build file executed is not the same.

I would like to expand open jfs's answer, which worked great for my problem: sorting two lists by a third, decorated list:

We can create our decorated list in any way, but in this case we will create it from the elements of one of the two original lists, that we want to sort:

# say we have the following list and we want to sort both by the algorithms name 
# (if we were to sort by the string_list, it would sort by the numerical 
# value in the strings)
string_list = ["0.123 Algo. XYZ", "0.345 Algo. BCD", "0.987 Algo. ABC"]
dict_list = [{"dict_xyz": "XYZ"}, {"dict_bcd": "BCD"}, {"dict_abc": "ABC"}]

# thus we need to create the decorator list, which we can now use to sort
decorated = [text[6:] for text in string_list]  
# decorated list to sort
>>> decorated
['Algo. XYZ', 'Algo. BCD', 'Algo. ABC']

Now we can apply jfs's solution to sort our two lists by the third

# create and sort the list of indices
sorted_indices = list(range(len(string_list)))
sorted_indices.sort(key=decorated.__getitem__)

# map sorted indices to the two, original lists
sorted_stringList = list(map(string_list.__getitem__, sorted_indices))
sorted_dictList = list(map(dict_list.__getitem__, sorted_indices))

# output
>>> sorted_stringList
['0.987 Algo. ABC', '0.345 Algo. BCD', '0.123 Algo. XYZ']
>>> sorted_dictList
[{'dict_abc': 'ABC'}, {'dict_bcd': 'BCD'}, {'dict_xyz': 'XYZ'}]

Here is the code:

// Input string.
const string input = "Dot Net Perls";

// Invoke GetBytes method.
// ... You can store this array as a field!
byte[] array = Encoding.ASCII.GetBytes(input);

// Loop through contents of the array.
foreach (byte element in array)
{
    Console.WriteLine("{0} = {1}", element, (char)element);
}

Another alternative is to use the heatmap function in seaborn to plot the covariance. This example uses the Auto data set from the ISLR package in R (the same as in the example you showed).

import pandas.rpy.common as com
import seaborn as sns
%matplotlib inline

# load the R package ISLR
infert = com.importr("ISLR")

# load the Auto dataset
auto_df = com.load_data('Auto')

# calculate the correlation matrix
corr = auto_df.corr()

# plot the heatmap
sns.heatmap(corr, 
        xticklabels=corr.columns,
        yticklabels=corr.columns)

If you wanted to be even more fancy, you can use Pandas Style, for example:

cmap = cmap=sns.diverging_palette(5, 250, as_cmap=True)

def magnify():
    return [dict(selector="th",
                 props=[("font-size", "7pt")]),
            dict(selector="td",
                 props=[('padding', "0em 0em")]),
            dict(selector="th:hover",
                 props=[("font-size", "12pt")]),
            dict(selector="tr:hover td:hover",
                 props=[('max-width', '200px'),
                        ('font-size', '12pt')])
]

corr.style.background_gradient(cmap, axis=1)\
    .set_properties(**{'max-width': '80px', 'font-size': '10pt'})\
    .set_caption("Hover to magify")\
    .set_precision(2)\
    .set_table_styles(magnify())

Smoke Testing:-

Smoke test is scripted, i.e you have either manual test cases or automated scripts for it.

Sanity Testing:-

Sanity tests are mostly non scripted.

In general you cannot rely on a fixed pixel size for fonts, the user may be scaling the screen and the defaults are not always the same (depends on DPI settings of the screen etc.).

Maybe have a look at this (pixel to point) and this link.

But of course you can set the font size to px, so that you do know how many pixels the font actually is. This may help if you really need a fixed layout, but this practice reduces accessibility of your web site.

You could use the INDIRECT function. This takes a string and converts it into a range

More info here

=INDIRECT("K"&A2)

But it's preferable to use INDEX as it is less volatile.

=INDEX(K:K,A2)

This returns a value or the reference to a value from within a table or range

More info here

Put either function into cell B2 and fill down.

The second parameter of findBy is for ORDER.

$ens = $em->getRepository('AcmeBinBundle:Marks')
          ->findBy(
             array('type'=> 'C12'), 
             array('id' => 'ASC')
           );

Follow these steps to begin using Angular Material.

Step 1: Install Angular Material

npm install --save @angular/material

Step 2: Animations

Some Material components depend on the Angular animations module in order to be able to do more advanced transitions. If you want these animations to work in your app, you have to install the @angular/animations module and include the BrowserAnimationsModule in your app.

npm install --save @angular/animations

Then

import {BrowserAnimationsModule} from '@angular/platform browser/animations';

@NgModule({
...
  imports: [BrowserAnimationsModule],
...
})
export class PizzaPartyAppModule { }

Step 3: Import the component modules

Import the NgModule for each component you want to use:

import {MdButtonModule, MdCheckboxModule} from '@angular/material';

@NgModule({
...
imports: [MdButtonModule, MdCheckboxModule],
...
 })
 export class PizzaPartyAppModule { }

be sure to import the Angular Material modules after Angular's BrowserModule, as the import order matters for NgModules

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';

import {MdCardModule} from '@angular/material';
@NgModule({
    declarations: [
        AppComponent,
        HeaderComponent,
        HomeComponent
    ],
    imports: [
        BrowserModule,
        FormsModule,
        HttpModule,
        MdCardModule
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule { }

Step 4: Include a theme

Including a theme is required to apply all of the core and theme styles to your application.

To get started with a prebuilt theme, include the following in your app's index.html:

<link href="../node_modules/@angular/material/prebuilt-themes/indigo-pink.css" rel="stylesheet">

You need to stop the submission if an error occured:

HTML

<form name ="myform" onsubmit="return validation();"> 

JS

if (document.myform.username.value == "") {
     document.getElementById('errors').innerHTML="*Please enter a username*";
     return false;
}

You can use String arrays to add jComboBox items

String [] items = { "First item", "Second item", "Third item", "Fourth item" };

JComboBox comboOne = new JComboBox (items);

Type in cmd.exe Powershell -Help and see the examples.

There is also a new option now in http://vimr.org/, which looks quite promising.

I don't know if this will be helpful for someone, but I had the same problem. I wrote pip install xlrd in the anaconda prompt while in the specific environment and it said it was installed, but when I looked at the installed packages it wasn't there. What solved the problem was "moving" (I don't know the terminology for it) into the Scripts folder of the specific environment and do the pip install xlrd there. Hope this is useful for someone :D

Here's an example that puts the Now() value in column A.

Sub move()
    Dim i As Integer
    Dim sh1 As Worksheet
    Dim sh2 As Worksheet
    Dim nextRow As Long
    Dim copyRange As Range
    Dim destRange As Range

    Application.ScreenUpdating = False

        Set sh1 = ActiveWorkbook.Worksheets("Sheet1")
        Set sh2 = ActiveWorkbook.Worksheets("Sheet2")
        Set copyRange = sh1.Range("A1:A5")

        i = Application.WorksheetFunction.CountA(sh2.Range("B:B")) + 4

        Set destRange = sh2.Range("B" & i)

        destRange.Resize(1, copyRange.Rows.Count).Value = Application.Transpose(copyRange.Value)
        destRange.Offset(0, -1).Value = Format(Now(), "MMM-DD-YYYY")

        copyRange.Clear

    Application.ScreenUpdating = True

End Sub

There are better ways of getting the last row in column B than using a While loop, plenty of examples around here. Some are better than others but depend on what you're doing and what your worksheet structure looks like. I used one here which assumes that column B is ALL empty except the rows/records you're moving. If that's not the case, or if B1:B3 have some values in them, you'd need to modify or use another method. Or you could just use your loop, but I'd search for alternatives :)

In Python 3.x the raw_input() of Python 2.x has been replaced by input() function. However in both the cases you cannot input multi-line strings, for that purpose you would need to get input from the user line by line and then .join() them using \n, or you can also take various lines and concatenate them using + operator separated by \n

To get multi-line input from the user you can go like:

no_of_lines = 5
lines = ""
for i in xrange(no_of_lines):
    lines+=input()+"\n"

print(lines)

Or

lines = []
while True:
    line = input()
    if line:
        lines.append(line)
    else:
        break
text = '\n'.join(lines)

Try something like this (should work for Apache and IIS):

if (empty($_SERVER['HTTPS']) || $_SERVER['HTTPS'] === "off") {
    $location = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    header('HTTP/1.1 301 Moved Permanently');
    header('Location: ' . $location);
    exit;
}

This worked for me:

1. Open control panel
2. click System
3. Then go to Change Environment Variables
4. Then click create a new environment variables
5. Create a new variable named ANDROID_HOME path C:\Android\sdk

i had the same case on linux ubuntu and just fixed it, it seems that OS was confused between the /root/.ssh/ and home/user/.ssh/ dir, what i did was:

1. removed all keys from root and home/user .shh directory.
2. generated a new key make sure to pay attention to the path of creation (/home/you/.ssh/id_rsa) or (/root/.ssh/id_rsa)
3. check heroku keys heroku keys
4. if keys in there clear heroku keys:clear
5. heroku keys:add now in here if heroku couldn't find a key and asked to generate one right no, and this mean you have the same issue as mine, do the add command like this heroku keys:add /root/.ssh/id_rsa.pub the path that you'll add will be the one that you got in step 2.
6. try git push heroku master now

All of the answers (at the time of this writing) assume each of Redis, MongoDB, and perhaps an SQL-based relational database are essentially the same tool: "store data". They don't consider data models at all.

MongoDB: Complex Data

MongoDB is a document store. To compare with an SQL-driven relational database: relational databases simplify to indexed CSV files, each file being a table; document stores simplify to indexed JSON files, each file being a document, with multiple files grouped together.

JSON files are similar in structure to XML and YAML files, and to dictionaries as in Python, so think of your data in that sort of hierarchy. When indexing, the structure is the key: A document contains named keys, which contain either further documents, arrays, or scalar values. Consider the below document.

{
  _id:  0x194f38dc491a,
  Name:  "John Smith",
  PhoneNumber:
    Home: "555 999-1234",
    Work: "555 999-9876",
    Mobile: "555 634-5789"
  Accounts:
    - "379-1111"
    - "379-2574"
    - "414-6731"
}

The above document has a key, PhoneNumber.Mobile, which has value 555 634-5789. You can search through a collection of documents where the key, PhoneNumber.Mobile, has some value; they're indexed.

It also has an array of Accounts which hold multiple indexes. It is possible to query for a document where Accounts contains exactly some subset of values, all of some subset of values, or any of some subset of values. That means you can search for Accounts = ["379-1111", "379-2574"] and not find the above; you can search for Accounts includes ["379-1111"] and find the above document; and you can search for Accounts includes any of ["974-3785","414-6731"] and find the above and whatever document includes account "974-3785", if any.

Documents go as deep as you want. PhoneNumber.Mobile could hold an array, or even a sub-document (PhoneNumber.Mobile.Work and PhoneNumber.Mobile.Personal). If your data is highly structured, documents are a large step up from relational databases.

If your data is mostly flat, relational, and rigidly structured, you're better off with a relational database. Again, the big sign is whether your data models best to a collection of interrelated CSV files or a collection of XML/JSON/YAML files.

For most projects, you'll have to compromise, accepting a minor work-around in some small areas where either SQL or Document Stores don't fit; for some large, complex projects storing a broad spread of data (many columns; rows are irrelevant), it will make sense to store some data in one model and other data in another model. Facebook uses both SQL and a graph database (where data is put into nodes, and nodes are connected to other nodes); Craigslist used to use MySQL and MongoDB, but had been looking into moving entirely onto MongoDB. These are places where the span and relationship of the data faces significant handicaps if put under one model.

Redis: Key-Value

Redis is, most basically, a key-value store. Redis lets you give it a key and look up a single value. Redis itself can store strings, lists, hashes, and a few other things; however, it only looks up by name.

Cache invalidation is one of computer science's hard problems; the other is naming things. That means you'll use Redis when you want to avoid hundreds of excess look-ups to a back-end, but you'll have to figure out when you need a new look-up.

The most obvious case of invalidation is update on write: if you read user:Simon:lingots = NOTFOUND, you might SELECT Lingots FROM Store s INNER JOIN UserProfile u ON s.UserID = u.UserID WHERE u.Username = Simon and store the result, 100, as SET user:Simon:lingots = 100. Then when you award Simon 5 lingots, you read user:Simon:lingots = 100, SET user:Simon:lingots = 105, and UPDATE Store s INNER JOIN UserProfile u ON s.UserID = u.UserID SET s.Lingots = 105 WHERE u.Username = Simon. Now you have 105 in your database and in Redis, and can get user:Simon:lingots without querying the database.

The second case is updating dependent information. Let's say you generate chunks of a page and cache their output. The header shows the player's experience, level, and amount of money; the player's Profile page has a block that shows their statistics; and so forth. The player gains some experience. Well, now you have several templates:Header:Simon, templates:StatsBox:Simon, templates:GrowthGraph:Simon, and so forth fields where you've cached the output of a half-dozen database queries run through a template engine. Normally, when you display these pages, you say:

$t = GetStringFromRedis("templates:StatsBox:" + $playerName);
if ($t == null) {
  $t = BuildTemplate("StatsBox.tmpl",
                     GetStatsFromDatabase($playerName));
  SetStringInRedis("Templates:StatsBox:" + $playerName, $t);
}
print $t;

Because you just updated the results of GetStatsFromDatabase("Simon"), you have to drop templates:*:Simon out of your key-value cache. When you try to render any of these templates, your application will churn away fetching data from your database (PostgreSQL, MongoDB) and inserting it into your template; then it will store the result in Redis and, hopefully, not bother making database queries and rendering templates the next time it displays that block of output.

Redis also lets you do publisher-subscribe message queues and such. That's another topic entirely. Point here is Redis is a key-value cache, which differs from a relational database or a document store.

Conclusion

Pick your tools based on your needs. The largest need is usually data model, as that determines how complex and error-prone your code is. Specialized applications will lean on performance, places where you write everything in a mixture of C and Assembly; most applications will just handle the generalized case and use a caching system such as Redis or Memcached, which is a lot faster than either a high-performance SQL database or a document store.

Thanks to @Pax Diablo, @bvmou and @Arachnid for the suggestion of using full datetimes throughout. If I have to accept datetime.time objects from an external source, then this seems to be an alternative add_secs_to_time() function:

def add_secs_to_time(timeval, secs_to_add):
    dummy_date = datetime.date(1, 1, 1)
    full_datetime = datetime.datetime.combine(dummy_date, timeval)
    added_datetime = full_datetime + datetime.timedelta(seconds=secs_to_add)
    return added_datetime.time()

This verbose code can be compressed to this one-liner:

(datetime.datetime.combine(datetime.date(1, 1, 1), timeval) + datetime.timedelta(seconds=secs_to_add)).time()

but I think I'd want to wrap that up in a function for code clarity anyway.

You have to pass $ in function()

<script>
jQuery(document).ready(function($){

// jQuery code is in here

});
</script>

I always use multiple statements with "-e"

$ sed -e 's:AND:\n&:g' -e 's:GROUP BY:\n&:g' -e 's:UNION:\n&:g' -e 's:FROM:\n&:g' file > readable.sql

This will append a '\n' before all AND's, GROUP BY's, UNION's and FROM's, whereas '&' means the matched string and '\n&' means you want to replace the matched string with an '\n' before the 'matched'

You can convert .jar file to .exe on these ways:

_{(source: viralpatel.net)}

1- JSmooth .exe wrapper:
JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself. When no VM is available, the wrapper can automatically download and install a suitable JVM, or simply display a message or redirect the user to a web site.

JSmooth provides a variety of wrappers for your java application, each of them having their own behaviour: Choose your flavour!

Download: http://jsmooth.sourceforge.net/

2- JarToExe 1.8
Jar2Exe is a tool to convert jar files into exe files. Following are the main features as describe in their website:

• Can generate “Console”, “Windows GUI”, “Windows Service” three types of exe files.
• Generated exe files can add program icons and version information.
• Generated exe files can encrypt and protect java programs, no temporary files will be generated when program runs.
• Generated exe files provide system tray icon support.
• Generated exe files provide record system event log support.
• Generated windows service exe files are able to install/uninstall itself, and support service pause/continue.
• New release of x64 version, can create 64 bits executives. (May 18, 2008)
• Both wizard mode and command line mode supported. (May 18, 2008)

Download: http://www.brothersoft.com/jartoexe-75019.html

3- Executor
Package your Java application as a jar, and Executor will turn the jar into a Windows exe file, indistinguishable from a native application. Simply double-clicking the exe file will invoke the Java Runtime Environment and launch your application.

Download: http://mpowers.net/executor/

EDIT: The above link is broken, but here is the page (with working download) from the Internet Archive. http://web.archive.org/web/20090316092154/http://mpowers.net/executor/

4- Advanced Installer
Advanced Installer lets you create Windows MSI installs in minutes. This also has Windows Vista support and also helps to create MSI packages in other languages.
Download: http://www.advancedinstaller.com/ Let me know other tools that you have used to convert JAR to EXE.

My Oracle is a bit rusty, but I think this would work:

SELECT * FROM TableA
WHERE ROWID IN ( SELECT MAX(ROWID) FROM TableA GROUP BY Language )

You can use HttpEntity to read both Body and Headers.

   @RequestMapping(value = "/restURL")
   public String serveRest(HttpEntity<String> httpEntity){
                MultiValueMap<String, String> headers = 
                httpEntity.getHeaders();
                Iterator<Map.Entry<String, List<String>>> s = 
                headers.entrySet().iterator();
                while(s.hasNext()) {
                    Map.Entry<String, List<String>> obj = s.next();
                    String key = obj.getKey();
                    List<String> value = obj.getValue();
                }
                
                String body = httpEntity.getBody();

    }

 WebClient client = new WebClient();
            using (Stream data = client.OpenRead(Text))
            {
                using (StreamReader reader = new StreamReader(data))
                {
                    string content = reader.ReadToEnd();
                    string pattern = @"((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\\\))+[\w\d:#@%/;$()~_?\+-=\\\.&]*)";
                    MatchCollection matches = Regex.Matches(content,pattern);
                    List<string> urls = new List<string>();
                    foreach (Match match in matches)
                    {
                            urls.Add(match.Value);
                    }

              }

Here you go. Just specify the chars you want to allow on the first line.

char[] chars = "abcdefghijklmnopqrstuvwxyz".toCharArray();
StringBuilder sb = new StringBuilder(20);
Random random = new Random();
for (int i = 0; i < 20; i++) {
    char c = chars[random.nextInt(chars.length)];
    sb.append(c);
}
String output = sb.toString();
System.out.println(output);

If you are using this to generate something sensitive like a password reset URL or session ID cookie or temporary password reset, be sure to use java.security.SecureRandom instead. Values produced by java.util.Random and java.util.concurrent.ThreadLocalRandom are mathematically predictable.

See my answer to Stack Overflow question Finish All previous activities.

What you need is to add the Intent.FLAG_CLEAR_TOP. This flag makes sure that all activities above the targeted activity in the stack are finished and that one is shown.

Another thing that you need is the SINGLE_TOP flag. With this one you prevent Android from creating a new activity if there is one already created in the stack.

Just be wary that if the activity was already created, the intent with these flags will be delivered in the method called onNewIntent(intent) (you need to overload it to handle it) in the target activity.

Then in onNewIntent you have a method called restart or something that will call finish() and launch a new intent toward itself, or have a repopulate() method that will set the new data. I prefer the second approach, it is less expensive and you can always extract the onCreate logic into a separate method that you can call for populate.

In my case when I use something like result.class.name I got something like Module1::class_name. But if we only want class_name, use

result.class.table_name.singularize

• Gendarme is an open source rules based static analyzer (similar to FXCop, but finds a lot of different problems).
• Clone Detective is a nice plug-in for Visual Studio that finds duplicate code.
• Also speaking of Mono, I find the act of compiling with the Mono compiler (if your code is platform independent enough to do that, a goal you might want to strive for anyway) finds tons of unreferenced variables and other Warnings that Visual Studio completely misses (even with the warning level set to 4).

You shouldn't be using the BinaryFormatter for this - that's for serializing .Net types to a binary file so they can be read back again as .Net types.

If it's stored in the database, hopefully, as a varbinary - then all you need to do is get the byte array from that (that will depend on your data access technology - EF and Linq to Sql, for example, will create a mapping that makes it trivial to get a byte array) and then write it to the file as you do in your last line of code.

With any luck - I'm hoping that fileContent here is the byte array? In which case you can just do

System.IO.File.WriteAllBytes("hello.pdf", fileContent);

I spent couple of hours with google and found the answer here

PUT => If user can update all or just a portion of the record, use PUT (user controls what gets updated)

PUT /users/123/email
[email protected]

PATCH => If user can only update a partial record, say just an email address (application controls what can be updated), use PATCH.

PATCH /users/123
[description of changes]

Why Patch

PUT method need more bandwidth or handle full resources instead on partial. So PATCH was introduced to reduce the bandwidth.

Explanation about PATCH

PATCH is a method that is not safe, nor idempotent, and allows full and partial updates and side-effects on other resources.

PATCH is a method which enclosed entity contains a set of instructions describing how a resource currently residing on the origin server should be modified to produce a new version.

PATCH /users/123
[
  { "op": "replace", "path": "/email", "value": "[email protected]" }
]

index=1

awk -F"," -v i=$index -v v=$value '$(i)==v' file

import os
current_file = os.path.abspath(os.path.dirname(__file__))
parent_of_parent_dir = os.path.join(current_file, '../../')

In general, I break lines before operators, and indent the subsequent lines:

Map<long parameterization> longMap
    = new HashMap<ditto>();

String longString = "some long text"
                  + " some more long text";

To me, the leading operator clearly conveys that "this line was continued from something else, it doesn't stand on its own." Other people, of course, have different preferences.

Use wildcards:

cp /home/ankur/folder/* /home/ankur/dest

If you don't want to copy all the files, you can use braces to select files:

cp /home/ankur/folder/{file{1,2},xyz,abc} /home/ankur/dest

This will copy file1, file2, xyz, and abc.

You should read the sections of the bash man page on Brace Expansion and Pathname Expansion for all the ways you can simplify this.

Another thing you can do is cd /home/ankur/folder. Then you can type just the filenames rather than the full pathnames, and you can use filename completion by typing Tab.

I know you said "ignore what the macro does", but people will find this question by searching based on the title, so I think discussion of further techniques to emulate functions with macros are warranted.

Closest I know of is:

#define MACRO(X,Y) \
do { \
    auto MACRO_tmp_1 = (X); \
    auto MACRO_tmp_2 = (Y); \
    using std::cout; \
    using std::endl; \
    cout << "1st arg is:" << (MACRO_tmp_1) << endl;    \
    cout << "2nd arg is:" << (MACRO_tmp_2) << endl;    \
    cout << "Sum is:" << (MACRO_tmp_1 + MACRO_tmp_2) << endl; \
} while(0)

This does the following:

• Works correctly in each of the stated contexts.
• Evaluates each of its arguments exactly once, which is a guaranteed feature of a function call (assuming in both cases no exceptions in any of those expressions).
• Acts on any types, by use of "auto" from C++0x. This is not yet standard C++, but there's no other way to get the tmp variables necessitated by the single-evaluation rule.
• Doesn't require the caller to have imported names from namespace std, which the original macro does, but a function would not.

However, it still differs from a function in that:

• In some invalid uses it may give different compiler errors or warnings.
• It goes wrong if X or Y contain uses of 'MACRO_tmp_1' or 'MACRO_tmp_2' from the surrounding scope.
• Related to the namespace std thing: a function uses its own lexical context to look up names, whereas a macro uses the context of its call site. There's no way to write a macro that behaves like a function in this respect.
• It can't be used as the return expression of a void function, which a void expression (such as the comma solution) can. This is even more of an issue when the desired return type is not void, especially when used as an lvalue. But the comma solution can't include using declarations, because they're statements, so pick one or use the ({ ... }) GNU extension.

You can try with both the ways with XML and programmatically. But the issue you may face is (below API 21) by doing it with XML will not work . So it's better to set it programmatically in your Activity / Fragment.

XML code:

<android.support.v7.widget.RecyclerView
      android:id="@+id/recycleView"
      android:layout_width="match_parent"
      android:visibility="gone"
      android:nestedScrollingEnabled="false"
      android:layout_height="wrap_content"
      android:layout_below="@+id/linearLayoutBottomText" /> 

Programmatically:

 recycleView = (RecyclerView) findViewById(R.id.recycleView);
 recycleView.setNestedScrollingEnabled(false);

Microsoft® SQL Server™ 2000 uses these SQL-92 keywords for outer joins specified in a FROM clause:

• LEFT OUTER JOIN or LEFT JOIN

• RIGHT OUTER JOIN or RIGHT JOIN

• FULL OUTER JOIN or FULL JOIN

From MSDN

The full outer join or full join returns all rows from both tables, matching up the rows wherever a match can be made and placing NULLs in the places where no matching row exists.

Try to use this free way to this, https://freenetexcel.codeplex.com

 Workbook workbook = new Workbook();

 workbook.LoadFromFile(@"..\..\parts.xls",ExcelVersion.Version97to2003);
 //Initialize worksheet
 Worksheet sheet = workbook.Worksheets[0];

 DataTable dataTable = sheet.ExportDataTable();

Just an observation - haven't found any documentation corroborating this

If a section contains another section, a h1-header in the inner section is displayed in a smaller font than a h1- header in outer section. When using div instead of section the inner div h1-header is diplayed as h1.

<section>
  <h1>Level1</h1>
  some text
  <section>
    <h1>Level2</h1>
    some more text
  </section>
</section>

-- the Level2 - header is displayed in a smaller font than the Level1 - header.

When using css to color h1 header, the inner h1 were also colored (behaves as regular h1). It's the same behaviour in Firefox 18, IE 10 and Chrome 28.

The URL decoder should only be used for decoding strings from the urls generated by html forms which are in the "application/x-www-form-urlencoded" mime type. This does not support html characters.

After a search I found a Translate class within the HTML Parser library.
