If you don't want any changes in design and definitely want it to just match a remote's branch, you can also just delete the branch and recreate it:

# Switch to some branch other than design
$ git br -D design
$ git co -b design origin/design            # Will set up design to track origin's design branch

If you define table type as InnoDB, you can use transactions. You will need set AUTOCOMMIT=0, and after you can issue COMMIT or ROLLBACK at the end of query or session to submit or cancel a transaction.

ROLLBACK -- will undo the changes that you have made

To directly answer the question of how to "get a copy of that file":

svn cat -r 666 file > file_r666

then you can view the newly created file_r666 with any viewer or comparison program, e.g.

kompare file_r666 file

nicely shows the differences.

I posted the answer because the accepted answer's commands do actually not give a copy of the file and because svn cat -r 666 file | vim does not work with my system (Vim: Error reading input, exiting...)

The accepted answer is not always correct. If you configure binary logging on MySQL, you can rollback the database to any previous point you still have a snapshot and binlog for.

7.5 Point-in-Time (Incremental) Recovery Using the Binary Log is a good starting point for learning about this facility.

in this example we run 2 line insert into query and if all of them true it run but if not no run anything and ROLLBACK

DECLARE @rowcount int  set @rowcount = 0 ; 
BEGIN TRANSACTION [Tran1]
BEGIN TRY 
 insert into [database].[dbo].[tbl1] (fld1) values('1') ;
    set @rowcount = (@rowcount + @@ROWCOUNT); 
 insert into [database].[dbo].[tbl2] (fld1) values('2') ;
    set @rowcount = (@rowcount + @@ROWCOUNT); 

IF @rowcount =  2
  COMMIT TRANSACTION[Tran1]
ELSE
  ROLLBACK TRANSACTION[Tran1]
END TRY
  BEGIN CATCH
  ROLLBACK TRANSACTION[Tran1]
END CATCH

To rollback the last migration you can do:

rake db:rollback

If you want to rollback a specific migration with a version you should do:

rake db:migrate:down VERSION=YOUR_MIGRATION_VERSION

For e.g. if the version is 20141201122027, you will do:

rake db:migrate:down VERSION=20141201122027

to rollback that specific migration.

First, Update your last perfect migration via this command :

Update-Database –TargetMigration

Example:

Update-Database -20180906131107_xxxx_xxxx

And, then delete your unused migration manually.

Have you tried:

ifconfig 10:35978f0 down

As the physical interface is 10 and the virtual aspect is after the colon :.

Everything is fine, just one mistake is there. Change this:

$query = mysql_query("SELECT username FROM Users WHERE username=$username", $con);
$query = mysql_query("SELECT Count(*) FROM Users WHERE username=$username, $con");

if (mysql_num_rows($query) != 0)
{
    echo "Username already exists";
}
else
{
  ...
}

SELECT * will not work, use with SELECT COUNT(*).

I solved it by using the developer tools for IE7 (its a toolbar) and adding a negative z-index to the container of the div that will be below that the other div.

I'm using EasyPHP in making my Thesis about Content Management System. So far, this tool is very good and easy to use.

I have defined one pattern to look for any of the ASCII Special Characters ranging between 032 to 126 except the alpha-numeric. You may use something like the one below:

To find any Special Character:

[ -\/:-@\[-\`{-~]

To find minimum of 1 and maximum of any count:

(?=.*[ -\/:-@\[-\`{-~]{1,})

These patterns have Special Characters ranging between 032 to 047, 058 to 064, 091 to 096, and 123 to 126.

Using the C++ API, the function name has slightly changed and it writes now:

#include <opencv2/imgproc/imgproc.hpp>

cv::Mat greyMat, colorMat;
cv::cvtColor(colorMat, greyMat, CV_BGR2GRAY);

The main difficulties are that the function is in the imgproc module (not in the core), and by default cv::Mat are in the Blue Green Red (BGR) order instead of the more common RGB.

OpenCV 3

Starting with OpenCV 3.0, there is yet another convention. Conversion codes are embedded in the namespace cv:: and are prefixed with COLOR. So, the example becomes then:

#include <opencv2/imgproc/imgproc.hpp>

cv::Mat greyMat, colorMat;
cv::cvtColor(colorMat, greyMat, cv::COLOR_BGR2GRAY);

As far as I have seen, the included file path hasn't changed (this is not a typo).

Try CSS:

<h2 style="color:#069">Process Report</h2>

If you have more than one h2 tags which should have the same color add a style tag to the head tag like this:

<style type="text/css">
h2 {
    color:#069;
}
</style>

ALTER TABLE (Your_Table_Name) MODIFY (Your_Column_Name) DATA_TYPE();

For you problem:

ALTER TABLE (Your_Table_Name) MODIFY (Your_Column_Name) DECIMAL(Precision, Scale); 

ApplicationId must be of type UniqueIdentifier. Your code works fine if you do:

DECLARE @TTEST TABLE
(
  TEST UNIQUEIDENTIFIER
)

DECLARE @UNIQUEX UNIQUEIDENTIFIER
SET @UNIQUEX = NEWID();

INSERT INTO @TTEST
(TEST)
VALUES
(@UNIQUEX);

SELECT * FROM @TTEST

Therefore I would say it is safe to assume that ApplicationId is not the correct data type.

With CSS 2 you can do this:

input[type='checkbox'] { ... }

This should be pretty widely supported by now. See support for browsers

Included page:

<!-- opening and closing tags of included page -->
<ui:composition ...>
</ui:composition>

Including page:

<!--the inclusion line in the including page with the content-->
<ui:include src="yourFile.xhtml"/>

• You start your included xhtml file with ui:composition as shown above.
• You include that file with ui:include in the including xhtml file as also shown above.

If you are working with core java, create your file(.properties) by right clicking your project. If the file is present inside your package or src folder it will throw an file not found error

I was looking at a project that makes it easy to create web apps as full fledged installable applications on the iPhone called QuickConnect, and found a solution that works, if you don't want your screen to be scrollable at all, which in my case I didn't.

In the above mentioned project/blog post, they mention a javascript function you can add to turn off the bouncing, which essentially boils down to this:

    document.ontouchmove = function(event){
        event.preventDefault();
    }

If you want to see more about how they implement it, simply download QuickConnect and check it out.... But basically all it does is call that javascript on page load... I tried just putting it in the head of my document, and it seems to work fine.

var dataArray = [];
var obj = jQuery.parseJSON(response);
  for( key in obj ) 
  dataArray.push([key.toString(), obj [key]]);
};

If you for some reason want to separate the act of creating and writing, the Java equivalent of touch is

try {
   //create a file named "testfile.txt" in the current working directory
   File myFile = new File("testfile.txt");
   if ( myFile.createNewFile() ) {
      System.out.println("Success!");
   } else {
      System.out.println("Failure!");
   }
} catch ( IOException ioe ) { ioe.printStackTrace(); }

createNewFile() does an existence check and file create atomically. This can be useful if you want to ensure you were the creator of the file before writing to it, for example.

var ref = new Firebase('https://your.firebaseio.com/');

Query query = ref.orderByChild('genre').equalTo('comedy');
query.addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        for (DataSnapshot movieSnapshot : dataSnapshot.getChildren()) {
            Movie movie = dataSnapshot.getValue(Movie.class);
            if (movie.getLead().equals('Jack Nicholson')) {
                console.log(movieSnapshot.getKey());
            }
        }
    }

    @Override
    public void onCancelled(FirebaseError firebaseError) {

    }
});

"I do not know if it is out of ignorance, but I do not like that kind of programming, as it is using exceptions to perform flow control."

In the Python world, using exceptions for flow control is common and normal.

Even the Python core developers use exceptions for flow-control and that style is heavily baked into the language (i.e. the iterator protocol uses StopIteration to signal loop termination).

In addition, the try-except-style is used to prevent the race-conditions inherent in some of the "look-before-you-leap" constructs. For example, testing os.path.exists results in information that may be out-of-date by the time you use it. Likewise, Queue.full returns information that may be stale. The try-except-else style will produce more reliable code in these cases.

"It my understanding that exceptions are not errors, they should only be used for exceptional conditions"

In some other languages, that rule reflects their cultural norms as reflected in their libraries. The "rule" is also based in-part on performance considerations for those languages.

The Python cultural norm is somewhat different. In many cases, you must use exceptions for control-flow. Also, the use of exceptions in Python does not slow the surrounding code and calling code as it does in some compiled languages (i.e. CPython already implements code for exception checking at every step, regardless of whether you actually use exceptions or not).

In other words, your understanding that "exceptions are for the exceptional" is a rule that makes sense in some other languages, but not for Python.

"However, if it is included in the language itself, there must be a good reason for it, isn't it?"

Besides helping to avoid race-conditions, exceptions are also very useful for pulling error-handling outside loops. This is a necessary optimization in interpreted languages which do not tend to have automatic loop invariant code motion.

Also, exceptions can simplify code quite a bit in common situations where the ability to handle an issue is far removed from where the issue arose. For example, it is common to have top level user-interface code calling code for business logic which in turn calls low-level routines. Situations arising in the low-level routines (such as duplicate records for unique keys in database accesses) can only be handled in top-level code (such as asking the user for a new key that doesn't conflict with existing keys). The use of exceptions for this kind of control-flow allows the mid-level routines to completely ignore the issue and be nicely decoupled from that aspect of flow-control.

There is a nice blog post on the indispensibility of exceptions here.

Also, see this Stack Overflow answer: Are exceptions really for exceptional errors?

"What is the reason for the try-except-else to exist?"

The else-clause itself is interesting. It runs when there is no exception but before the finally-clause. That is its primary purpose.

Without the else-clause, the only option to run additional code before finalization would be the clumsy practice of adding the code to the try-clause. That is clumsy because it risks raising exceptions in code that wasn't intended to be protected by the try-block.

The use-case of running additional unprotected code prior to finalization doesn't arise very often. So, don't expect to see many examples in published code. It is somewhat rare.

Another use-case for the else-clause is to perform actions that must occur when no exception occurs and that do not occur when exceptions are handled. For example:

recip = float('Inf')
try:
    recip = 1 / f(x)
except ZeroDivisionError:
    logging.info('Infinite result')
else:
    logging.info('Finite result')

Another example occurs in unittest runners:

try:
    tests_run += 1
    run_testcase(case)
except Exception:
    tests_failed += 1
    logging.exception('Failing test case: %r', case)
    print('F', end='')
else:
    logging.info('Successful test case: %r', case)
    print('.', end='')

Lastly, the most common use of an else-clause in a try-block is for a bit of beautification (aligning the exceptional outcomes and non-exceptional outcomes at the same level of indentation). This use is always optional and isn't strictly necessary.

I always use this in jQuery for disabling links

$("form a").attr("disabled", "disabled");

Class WebMvcConfigurerAdapter is deprecated as of 5.0 WebMvcConfigurer has default methods and can be implemented directly without the need for this adapter. For this case:

@Configuration
@EnableWebMvc
public class WebMvcConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedOrigins("http://localhost:3000");
    }
}

In the service.ts file -

a. import 'of' from observable/of
b. create a json list
c. return json object using Observable.of()

import { of } from 'rxjs/observable/of';

@Injectable()
export class ClientListService {
    private clientList;

    constructor() {

            {name: 'ghi', address: 'Panagarh'},
            {name: 'jkl', address: 'Panagarh 2'},
        ];
    }

    getClientList () {
        return Observable.of(this.clientList);
    }
};

In the component where we are calling the get function of the service -

this.clientListService.getClientList().subscribe(res => this.clientList = res);

Run the below commands as admin to install NuGet using Powershell:

The documentation for focusout says (emphasis mine):

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

The same distinction exists between the focusin and focus events.

Your error appears when you have modified a file and the branch that you are switching to has changes for this file too (from latest merge point).

Your options, as I see it, are - commit, and then amend this commit with extra changes (you can modify commits in git, as long as they're not pushed); or - use stash:

git stash save your-file-name
git checkout master
# do whatever you had to do with master
git checkout staging
git stash pop

git stash save will create stash that contains your changes, but it isn't associated with any commit or even branch. git stash pop will apply latest stash entry to your current branch, restoring saved changes and removing it from stash.

I had this problem, but not via the Header. My placeholder was in the body. So I replaced all the <%= with <%# and did

protected void Page_Load(object sender, EventArgs e)
{
    Page.Header.DataBind();    
}

and it worked.

Okay,I have re-installed the package via pip even that didn't help. And then I rsync'ed the entire /usr/lib/python-2.7 directory from other working machine with similar configuration to the current machine.It started working. I don't have any idea ,what was wrong with my setup. I see some difference "print sys.path" output earlier and now. but now my issue is resolved by this work around.

EDIT:Found the real solution for my setup. upgrading "sqlalchemy only doesn't solve the issue" I also need to upgrade flask-sqlalchemy that resolved the issue.

        //create PdfReader object to read from the existing document
        using (PdfReader reader = new PdfReader(pathin))
        //create PdfStamper object to write to get the pages from reader 
        using (PdfStamper stamper = new PdfStamper(reader, new FileStream(pathout, FileMode.Create)))
        {
            //select two pages from the original document
            reader.SelectPages("1-2");

            //gettins the page size in order to substract from the iTextSharp coordinates
            var pageSize = reader.GetPageSize(1);

            // PdfContentByte from stamper to add content to the pages over the original content
            PdfContentByte pbover = stamper.GetOverContent(1);

            //add content to the page using ColumnText
            Font font = new Font();
            font.Size = 45;

            //setting up the X and Y coordinates of the document
            int x = point.X;
            int y = point.Y;

            y = (int) (pageSize.Height - y);

            ColumnText.ShowTextAligned(pbover, Element.ALIGN_CENTER, new Phrase(textToAdd, font), x, y, 0);
        }
    }

I prefer to use :

then you can edit work and save

Here is a simple code for javascript validation, and after it validates it will clean the input file.

<input type="file" id="image" accept="image/*" onChange="validate(this.value)"/>

function validate(file) {
    var ext = file.split(".");
    ext = ext[ext.length-1].toLowerCase();      
    var arrayExtensions = ["jpg" , "jpeg", "png", "bmp", "gif"];

    if (arrayExtensions.lastIndexOf(ext) == -1) {
        alert("Wrong extension type.");
        $("#image").val("");
    }
}

If they are in the same directory as your script that contains:

./a.sh > /dev/null 2>&1 &
./b.sh > /dev/null 2>&1 &

The & at the end is what makes your script run in the background.

The > /dev/null 2>&1 part is not necessary - it redirects the stdout and stderr streams so you don't have to see them on the terminal, which you may want to do for noisy scripts with lots of output.

according to above ideas, I created a shell script that to make a proxy environment for composer.

#!/bin/bash
export HTTP_PROXY=http://127.0.0.1:8888/
export HTTPS_PROXY=http://127.0.0.1:8888/
zsh # you can alse use bash or other shell

This piece of code is in a file named ~/bin/proxy_mode_shell and it will create a new zsh shell instance when you need proxy. After update finished, you can simply press key Ctrl+D to quit the proxy mode.

add export PATH=~/bin:$PATH to ~/.bashrc or ~/.zshrc if you cannot run proxy_mode_shell directly.

Deleting files and folders

If you want to delete an item from the repository, but keep it locally as an unversioned file/folder, use Extended Context Menu ? Delete (keep local). You have to hold the Shift key while right clicking on the item in the explorer list pane (right pane) in order to see this in the extended context menu.

Delete completely:
right mouse click ? Menu ? Delete

Delete & Keep local:
Shift + right mouse click ? Menu ? Delete

This looks a little ugly. Is it possible to cast an entire stream to a different type? Like cast Stream<Object> to a Stream<Client>?

No that wouldn't be possible. This is not new in Java 8. This is specific to generics. A List<Object> is not a super type of List<String>, so you can't just cast a List<Object> to a List<String>.

Similar is the issue here. You can't cast Stream<Object> to Stream<Client>. Of course you can cast it indirectly like this:

Stream<Client> intStream = (Stream<Client>) (Stream<?>)stream;

but that is not safe, and might fail at runtime. The underlying reason for this is, generics in Java are implemented using erasure. So, there is no type information available about which type of Stream it is at runtime. Everything is just Stream.

BTW, what's wrong with your approach? Looks fine to me.

    /**
     * Check if a number is even or not using modulus operator.
     *
     * @param number the number to be checked.
     * @return {@code true} if the given number is even, otherwise {@code false}.
     */
    public static boolean isEven(int number) {
        return number % 2 == 0;
    }

    /**
     * Check if a number is even or not using & operator.
     *
     * @param number the number to be checked.
     * @return {@code true} if the given number is even, otherwise {@code false}.
     */
    public static boolean isEvenFaster(int number) {
        return (number & 1) == 0;

The simplest solution I can think of is this method, which will return the modified URI. I feel like most of you are working way too hard.

function setParam(uri, key, val) {
    return uri
        .replace(new RegExp("([?&]"+key+"(?=[=&#]|$)[^#&]*|(?=#|$))"), "&"+key+"="+encodeURIComponent(val))
        .replace(/^([^?&]+)&/, "$1?");
}

For some reason classLoader.getResource() always returned null when I deployed the web application to WildFly 14. getting classLoader from getClass().getClassLoader() or Thread.currentThread().getContextClassLoader() returns null.

getClass().getClassLoader() API doc says,

"Returns the class loader for the class. Some implementations may use null to represent the bootstrap class loader. This method will return null in such implementations if this class was loaded by the bootstrap class loader."

may be if you are using WildFly and yours web application try this

request.getServletContext().getResource() returned the resource url. Here request is an object of ServletRequest.

Good question. :) I don't have a complete answer...

That said, you can get a list of remote tags via git ls-remote. To list the tags in the repository referenced by origin, you'd run:

git ls-remote --tags origin

That returns a list of hashes and friendly tag names, like:

94bf6de8315d9a7b22385e86e1f5add9183bcb3c        refs/tags/v0.1.3
cc047da6604bdd9a0e5ecbba3375ba6f09eed09d        refs/tags/v0.1.4
...
2f2e45bedf67dedb8d1dc0d02612345ee5c893f2        refs/tags/v0.5.4

You could certainly put together a bash script to compare the tags generated by this list with the tags you have locally. Take a look at git show-ref --tags, which generates the tag names in the same form as git ls-remote).

As an aside, git show-ref has an option that does the opposite of what you'd like. The following command would list all the tags on the remote branch that you don't have locally:

git ls-remote --tags origin | git show-ref --tags --exclude-existing

I would continue your "convert number to string" approach. However, you will realize that your proposed algorithm fails if your ID is a prime and greater than 52.

Theoretical background

You need a Bijective Function f. This is necessary so that you can find a inverse function g('abc') = 123 for your f(123) = 'abc' function. This means:

• There must be no x1, x2 (with x1 ? x2) that will make f(x1) = f(x2),
• and for every y you must be able to find an x so that f(x) = y.

How to convert the ID to a shortened URL

1. Think of an alphabet we want to use. In your case, that's [a-zA-Z0-9]. It contains 62 letters.

2. Take an auto-generated, unique numerical key (the auto-incremented id of a MySQL table for example).

   For this example, I will use 125₁₀ (125 with a base of 10).

3. Now you have to convert 125₁₀ to X₆₂ (base 62).

   125₁₀ = 2×62¹ + 1×62⁰ = [2,1]

   This requires the use of integer division and modulo. A pseudo-code example:

   digits = []
   
   while num > 0
     remainder = modulo(num, 62)
     digits.push(remainder)
     num = divide(num, 62)
   
   digits = digits.reverse
   

   Now map the indices 2 and 1 to your alphabet. This is how your mapping (with an array for example) could look like:

   0  ? a
   1  ? b
   ...
   25 ? z
   ...
   52 ? 0
   61 ? 9
   

   With 2 ? c and 1 ? b, you will receive cb₆₂ as the shortened URL.

   http://shor.ty/cb
   

How to resolve a shortened URL to the initial ID

The reverse is even easier. You just do a reverse lookup in your alphabet.

1. e9a₆₂ will be resolved to "4th, 61st, and 0th letter in the alphabet".

   e9a₆₂ = [4,61,0] = 4×62² + 61×62¹ + 0×62⁰ = 19158₁₀

2. Now find your database-record with WHERE id = 19158 and do the redirect.

If all you want to do is change a single line, use \r. \r means carriage return. It's effect is solely to put the caret back at the start of the current line. It does not erase anything. Similarly, \b can be used to go one character backward. (some terminals may not support all those features)

I'm running Eclipse Indigo 64 bit on Windows 7 64 bit and I kept getting missing dependency errors associated with Maven and other plugins using the JBoss Tools 3.3.X latest download. Here is the link.

So, I opted to only install Hibernate Tools with nothing else by typing in "hibernate" at the top of the install software dialog in eclipse. Only 4 items showed up, so that is all I installed. It worked fine with no problems. Here is the tutorial that I used to get it installed properly after several failed attempts.

I don't know if part of this was due to having a lot of plugins already installed or if this is the best solution or not, but I thought I'd share it with everyone.

You can use this below.

rename --no-act 's/\.html$/\.php/' *.html */*.html

Go to Project-><Projectname> Properties. Then click on the Debug tab, and fill in your arguments in the textbox called Command line arguments.

the over partition keyword is as if we are partitioning the data by client_id creation a subset of each client id

select client_id, operation_date,
       row_number() count(*) over (partition by client_id order by client_id ) as operationctrbyclient
from client_operations e
order by e.client_id;

this query will return the number of operations done by the client_id

$("html, body").scrollTop($(element).offset().top); // <-- Also integer can be used

Before actually answering your question:

Parameters in a URL (e.g. key=listOfUsers/user1) are GET parameters and you shouldn't be using them for POST requests. A quick explanation of the difference between GET and POST can be found here.

In your case, to make use of REST principles, you should probably have:

http://ip:5000/users
http://ip:5000/users/<user_id>

Then, on each URL, you can define the behaviour of different HTTP methods (GET, POST, PUT, DELETE). For example, on /users/<user_id>, you want the following:

GET /users/<user_id> - return the information for <user_id>
POST /users/<user_id> - modify/update the information for <user_id> by providing the data
PUT - I will omit this for now as it is similar enough to `POST` at this level of depth
DELETE /users/<user_id> - delete user with ID <user_id> 

So, in your example, you want do a POST to /users/user_1 with the POST data being "John". Then the XPath expression or whatever other way you want to access your data should be hidden from the user and not tightly couple to the URL. This way, if you decide to change the way you store and access data, instead of all your URL's changing, you will simply have to change the code on the server-side.

Now, the answer to your question: Below is a basic semi-pseudocode of how you can achieve what I mentioned above:

from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/users/<user_id>', methods = ['GET', 'POST', 'DELETE'])
def user(user_id):
    if request.method == 'GET':
        """return the information for <user_id>"""
        .
        .
        .
    if request.method == 'POST':
        """modify/update the information for <user_id>"""
        # you can use <user_id>, which is a str but could
        # changed to be int or whatever you want, along
        # with your lxml knowledge to make the required
        # changes
        data = request.form # a multidict containing POST data
        .
        .
        .
    if request.method == 'DELETE':
        """delete user with ID <user_id>"""
        .
        .
        .
    else:
        # POST Error 405 Method Not Allowed
        .
        .
        .

There are a lot of other things to consider like the POST request content-type but I think what I've said so far should be a reasonable starting point. I know I haven't directly answered the exact question you were asking but I hope this helps you. I will make some edits/additions later as well.

Thanks and I hope this is helpful. Please do let me know if I have gotten something wrong.

I faced a problem upgrading pip from version 9.0.1 to 9.0.3 The upgrade failed middle way(after uninstalling version 9.0.1 and without installing version 9.0.3). This usually creates a broken pip file. Broken pip can be solved by the command-->

easy_install pip

Which usually installs the latest version of pip, and solves the issue. In order to confirm, type

pip --version

Hope this was helpfull...

Since there is a delimiter, you should use that instead of worrying about how long the md5 is.

>>> s = "416d76b8811b0ddae2fdad8f4721ddbe|d4f656ee006e248f2f3a8a93a8aec5868788b927|12a5f648928f8e0b5376d2cc07de8e4cbf9f7ccbadb97d898373f85f0a75c47f"
>>> md5sum, delim, rest = s.partition('|')
>>> md5sum
'416d76b8811b0ddae2fdad8f4721ddbe'

Alternatively

>>> md5sum, sha1sum, sha5sum = s.split('|')
>>> md5sum
'416d76b8811b0ddae2fdad8f4721ddbe'
>>> sha1sum
'd4f656ee006e248f2f3a8a93a8aec5868788b927'
>>> sha5sum
'12a5f648928f8e0b5376d2cc07de8e4cbf9f7ccbadb97d898373f85f0a75c47f'

If you want the date, given a month and a year, this seems about right:

public static DateTime GetLastDayOfMonth(this DateTime dateTime)
{
    return new DateTime(dateTime.Year, dateTime.Month, DateTime.DaysInMonth(dateTime.Year, dateTime.Month));
}

if you used the java 7, you could have used the following Date Time Pattern. Seems like this pattern is not supported in the Earlier version of java.

String dateTimeString  = "2010-03-01T00:00:00-08:00";
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX");
Date date = df.parse(dateTimeString);

For More information refer to the SimpleDateFormat documentation.

Move the session_start(); to top of the page always.

<?php
@ob_start();
session_start();
?>

To expand a little on Andrew's answer: The fact that regular expressions define extractors can be used to decompose the substrings matched by the regex very nicely using Scala's pattern matching, e.g.:

val Process = """([a-cA-C])([^\s]+)""".r // define first, rest is non-space
for (p <- Process findAllIn "aha bah Cah dah") p match {
  case Process("b", _) => println("first: 'a', some rest")
  case Process(_, rest) => println("some first, rest: " + rest)
  // etc.
}

You can use Programmatic Navigation.In order to go back, you use this:

router.go(n) 

Where n can be positive or negative (to go back). This is the same as history.back().So you can have your element like this:

<a @click="$router.go(-1)">back</a>

All the answers above are helpful but none solved my issue. In my production file, my STATIC_URL was https://<URL>/static and I used the same STATIC_URL in my dev settings.py file.

This causes a silent failure in django/conf/urls/static.py.

The test elif not settings.DEBUG or '://' in prefix: picks up the '//' in the URL and does not add the static URL pattern, causing no static files to be found.

It would be thoughtful if Django spit out an error message stating you can't use a http(s):// with DEBUG = True

I had to change STATIC_URL to be '/static/'

The other answers are preferable, but for a pure Bash solution, I've modified the script in my answer here to be able to output a continuous stream of hex characters representing the contents of a file. (Its normal mode is to emulate hexdump -C.)

If the list to compare against is large, (ie the manilaListRange range in the example above), it is a smart move to use the match function. It avoids the use of a loop which could slow down the procedure. If you can ensure that the manilaListRange is all upper or lower case then this seems to be the best option to me. It is quick to apply 'UCase' or 'LCase' as you do your match.

If you did not have control over the ManilaListRange then you might have to resort to looping through this range in which case there are many ways to compare 'search', 'Instr', 'replace' etc.

You could use display: table-row-group for your div.

<table>
  <div style="display: table-row-group">
    <tr><td></td></tr>
  </div>
  <div style="display: table-row-group">
    <tr><td></td></tr>
  </div>
</table>

Yes, that's usually happens after 1440s (24 minutes)

Here's a script that claims to be able to fix this.

Get admin rights to your local SQL Server Express with this simple script

Download link to the script

Description

This command script allows you to easily add yourself to the sysadmin role of a local SQL Server instance. You must be a member of the Windows local Administrators group, or have access to the credentials of a user who is. The script supports SQL Server 2005 and later.

The script is most useful if you are a developer trying to use SQL Server 2008 Express that was installed by someone else. In this situation you usually won't have admin rights to the SQL Server 2008 Express instance, since by default only the person installing SQL Server 2008 is granted administrative privileges.

The user who installed SQL Server 2008 Express can use SQL Server Management Studio to grant the necessary privileges to you. But what if SQL Server Management Studio was not installed? Or worse if the installing user is not available anymore?

This script fixes the problem in just a few clicks!

Note: You will need to provide the BAT file with an 'Instance Name' (Probably going to be 'MSSQLSERVER' - but it might not be): you can get the value by first running the following in the "Microsoft SQL Server Management Console":

 SELECT @@servicename

Then copy the result to use when the BAT file prompts for 'SQL instance name'.

The color and window sizing are defined by the shortcut LNK file. I think I found a way that will do what you need, try this:

explorer.exe "Windows PowerShell.lnk"

The LNK file is in the all user start menu which is located in different places depending whether your on XP or Windows 7. In 7 the LNK file is here:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Windows PowerShell

I know this is from quite a while back, but I found a quite interesting answer, so here goes:

-round(-x-0.5)

This fixes the edges cases and works for both positive and negative numbers, and doesn't require any function import

Cheers

1. The function expects a string.

2. file_exists() does not work properly with HTTP URLs.

use text transform property in your style tag

textTransform:'uppercase'

Instead of doing all these.. cant you use a simpler approach as shown below.

Response.ClearContent();
            Response.AddHeader("content-disposition", "attachment; filename=" + strFileName);
            Response.ContentType = "application/excel";
            System.IO.StringWriter sw = new System.IO.StringWriter();
            HtmlTextWriter htw = new HtmlTextWriter(sw);
            gv.RenderControl(htw);
            Response.Write(sw.ToString());
            Response.End();

You can get the entire walkthrough here

You suggested "Catching any unexpected errors and return some error code signaling "unexpected situation" " but couldn't find an appropriate error code.

Guess what: That's what 5xx is there for.

Use itoa, as is shown here.

char buf[5];
// Convert 123 to string [buf]
itoa(123, buf, 10);

buf will be a string array as you documented. You might need to increase the size of the buffer.

The most recent version of Sublime has fixed this issue, click on Preferences, click on Theme select Adaptive.sublime-theme. This will change the sidebar to a dark colored background.

I just want to edit this for posterity that the tags for oracle weren't added when I answered this question. My response was more applicable to MS SQL.

Merge join is the best possible as it exploits the ordering, resulting in a single pass down the tables to do the join. IF you have two tables (or covering indexes) that have their ordering the same such as a primary key and an index of a table on that key then a merge join would result if you performed that action.

Hash join is the next best, as it's usually done when one table has a small number (relatively) of items, its effectively creating a temp table with hashes for each row which is then searched continuously to create the join.

Worst case is nested loop which is order (n * m) which means there is no ordering or size to exploit and the join is simply, for each row in table x, search table y for joins to do.

    $where.= '(';
    $where.= 'admin_trek.trek='."%$search%".'  AND ';
    $where.= 'admin_trek.state_id='."$search".'  OR ';
    $where.= 'admin_trek.difficulty='."$search".' OR ';
    $where.= 'admin_trek.month='."$search".'  AND ';
    $where.= 'admin_trek.status = 1)';

    $this->db->select('*');
    $this->db->from('admin_trek');
    $this->db->join('admin_difficulty',admin_difficulty.difficulty_id = admin_trek.difficulty');
    $this->db->where($where); 
    $query = $this->db->get();

Be aware that changing locale is process-wide and not thread safe (iow., can have side effects or can affect other code executed within the same process).

My proposition: check out the Babel package. Some means of integrating with Django templates are available.

If you are using fpdf, in order to be able to use line breaks you will need to use a multi-line text cell as described here.

If you use this, then line breaks in your text should be interpreted and converted correctly.

Just a quick example:

$pdf->Multicell(0,2,"This is a multi-line text string\nNew line\nNew line"); 

Here, 2 is the height of the multi-line text box. I don't know what units that's measured in or if you can just set it to 0 and ignore it. Perhaps try it with a large number if at first it doesn't work.

Put the text file in the assets directory. If there isnt an assets dir create one in the root of the project. Then you can use Context.getAssets().open("BlockForTest.txt"); to open a stream to this file.

You could check with:

($Member.PropertyNames -contains "Name") this will check for the Named property

EDIT: Maybe your class for sending emails has an option for HTML emails and then you can use <br />

1) Double-quotes

$output = "Good news! The item# $item_number  on which you placed a bid of \$ $bid_price is now available for purchase at your bid price.\nThe seller, $bid_user is making this offer.\n\nItem Title : $title\n\nAll the best,\n $bid_user\n$email\n";

If you use double-quotes then \n will work (there will be no newline in browser but see the source code in your browser - the \n characters will be replaced for newlines)

2) Single quotes doesn't have the effect as the double-quotes above:

$output = 'Good news! The item# $item_number  on which you placed a bid of \$ $bid_price is now available for purchase at your bid price.\nThe seller, $bid_user is making this offer.\n\nItem Title : $title\n\nAll the best,\n $bid_user\n$email\n';

all characters will be printed as is (even variables!)

3) Line breaks in HTML

$html_output = "Good news! The item# $item_number  on which you placed a bid of <br />$ $bid_price is now available for purchase at your bid price.<br />The seller, $bid_user is making this offer.<br /><br />Item Title : $title<br /><br />All the best,<br /> $bid_user<br />$email<br />";

• There will be line breaks in your browser and variables will be replaced with their content.

Preserve the name of the column and avoid extra column addition by using the same name as input column:

changedTypedf = joindf.withColumn("show", joindf["show"].cast(DoubleType()))

I'm using this:

if(count($array)==count(array_count_values($array))){
    echo("all values are unique");
}else{
    echo("there's dupe values");
}

I don't know if it's the fastest but works pretty good so far

Well, the simplest way using LINQ would be something like this:

list = list.OrderBy(x => x.AVC ? 0 : 1)
           .ToList();

or

list = list.OrderByDescending(x => x.AVC)
           .ToList();

I believe that the natural ordering of bool values is false < true, but the first form makes it clearer IMO, because everyone knows that 0 < 1.

Note that this won't sort the original list itself - it will create a new list, and assign the reference back to the list variable. If you want to sort in place, you should use the List<T>.Sort method.

The answer given here works for some MVC versions but not for others.

The simple solution worked for MVC1 but on upgrading to MVC2 the views were no longer being compliled. This was due to a bug in the website project files. See this Haacked article.

See this: http://haacked.com/archive/2011/05/09/compiling-mvc-views-in-a-build-environment.aspx

The issue here is that JSON, as a format, is generally parsed in full and then handled in-memory, which for such a large amount of data is clearly problematic.

The solution to this is to work with the data as a stream - reading part of the file, working with it, and then repeating.

The best option appears to be using something like ijson - a module that will work with JSON as a stream, rather than as a block file.

Edit: Also worth a look - kashif's comment about json-streamer and Henrik Heino's comment about bigjson.

I will add for those that get stuck trying to run PHP (Laravel in may case) or other unique IIS hosting situation with the 405 error, that you need to change the verbs in the handler for that for that specific situation... so since I was using PHP I went to the PHP handler and in the Request Restrictions, then Verbs tab, add the verbs you need. This was all I needed to add to the web.config to enable CORS in Laravel.

<handlers>
  <remove name="php-5.6.40" />
  <add name="php-5.6.40" path="*.php" verb="GET,HEAD,POST,PUT,DELETE,OPTIONS" modules="FastCgiModule" scriptProcessor="C:\Program Files (x86)\PHP\v5.6\php-cgi.exe" resourceType="Either" requireAccess="Script" />
</handlers>

i was also facing the same issue, I resolved it by after selecting the Google's font that i was using, then I clicked on (Family-Selected) minimized tab and then clicked on "CUSTOMIZE" button. Then I selected the font weights that I want and then embedded the updated link in my html..

1)Goto Server tab 2)Right on server -> general -> click on switch location. 3)Double click on the server -> under server location -> select tomcat installation. 4) restart the server.

Well, it generally depends on the shell. For bash, it marks the variable as "exportable" meaning that it will show up in the environment for any child processes you run.

Non-exported variables are only visible from the current process (the shell).

From the bash man page:

export [-fn] [name[=word]] ...
export -p

The supplied names are marked for automatic export to the environment of subsequently executed commands.

If the -f option is given, the names refer to functions. If no names are given, or if the -p option is supplied, a list of all names that are exported in this shell is printed.

The -n option causes the export property to be removed from each name.

If a variable name is followed by =word, the value of the variable is set to word.

export returns an exit status of 0 unless an invalid option is encountered, one of the names is not a valid shell variable name, or -f is supplied with a name that is not a function.

You can also set variables as exportable with the typeset command and automatically mark all future variable creations or modifications as such, with set -a.

As I mentioned in lyceus answer, his code will fail on non-English locale Windows because then the output of mode may not contain the substrings "columns" or "lines":

You can find the correct substring without looking for text:

 preg_match('/---+(\n[^|]+?){2}(?<cols>\d+)/', `mode`, $matches);
 $cols = $matches['cols'];

Note that I'm not even bothering with lines because it's unreliable (and I actually don't care about them).

Edit: According to comments about Windows 8 (oh you...), I think this may be more reliable:

 preg_match('/CON.*:(\n[^|]+?){3}(?<cols>\d+)/', `mode`, $matches);
 $cols = $matches['cols'];

Do test it out though, because I didn't test it.

If you want to use it in JavaScript then you can use

str.replace("SP","\\SP");

But in Java

str.replaceAll("SP","\\SP");

will work perfectly.

SP: special character

Otherwise you can use Apache's EscapeUtil. It will solve your problem.

Try with this

public class ConnectionBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {


    if (<Check internet connection available >) { 
        Toast.makeText(context, "connect to the internet", Toast.LENGTH_LONG).show();

        /*upload background upload service*/
        Intent serviceIntent = new Intent(context,<your service class>);
        context.startService(serviceIntent);


    }else{
        Toast.makeText(context, "Connection failed", Toast.LENGTH_LONG).show();

    }
    }
}

As soon as internet connection trigger, this (BroadcastReciever) will be loaded

I wrote a solution for this to practice myself. It doesn't seem nearly as awesome as the other answers posted, but I'm going to post it anyway, and then learn how to do this using the other methods as well. Enjoy:

public static Integer[] countItems(String[] arr)
{
    List<Integer> itemCount = new ArrayList<Integer>();
    Integer counter = 0;
    String lastItem = arr[0];

    for(int i = 0; i < arr.length; i++)
    {
        if(arr[i].equals(lastItem))
        {
            counter++;
        }
        else
        {
            itemCount.add(counter);
            counter = 1;
        }
        lastItem = arr[i];
    }
    itemCount.add(counter);

    return itemCount.toArray(new Integer[itemCount.size()]);
}

public static void main(String[] args)
{
    String[] array = {"name1","name1","name2","name2", "name2", "name3",
            "name1","name1","name2","name2", "name2", "name3"};
    Arrays.sort(array);
    Integer[] cArr = countItems(array);
    int num = 0;
    for(int i = 0; i < cArr.length; i++)
    {
        num += cArr[i]-1;
        System.out.println(array[num] + ": " + cArr[i].toString());
    }
}

You seem to be using grep() like the Unix grep utility, which is wrong.

Perl's grep() in scalar context evaluates the expression for each element of a list and returns the number of times the expression was true. So when $match contains any "true" value, grep($match, @array) in scalar context will always return the number of elements in @array.

Instead, try using the pattern matching operator:

if (grep /$match/, @array) {
    print "found it\n";
}

We are using Response.SetCookie() for update the old one cookies and Response.Cookies.Add() are use to add the new cookies. Here below code CompanyId is update in old cookie[OldCookieName].

HttpCookie cookie = Request.Cookies["OldCookieName"];//Get the existing cookie by cookie name.
cookie.Values["CompanyID"] = Convert.ToString(CompanyId);
Response.SetCookie(cookie); //SetCookie() is used for update the cookie.
Response.Cookies.Add(cookie); //The Cookie.Add() used for Add the cookie.

SQL Server autocreates indices for Primary Keys, but not for Foreign Keys. Create the index for the Foreign Keys. It's probably worth the overhead.

It can be done using classes from the official bootstrap 3.x version, without any custom css.

Use input-group-addon before the input tag, inside of input-group then use any of the glyphicons, here is the code

<form>
  <div class="form-group">
    <div class="col-xs-5">
      <div class="input-group">
          <span class="input-group-addon transparent"><span class="glyphicon glyphicon-user"></span></span>
          <input class="form-control left-border-none" placeholder="User Name" type="text" name="username">
      </div>
    </div>
  </div>
</form>

Here is the output

To customise it further add a couple of lines of custom css to your own custom.css file (adjust padding if needed)

.transparent {
    background-color: transparent !important;
    box-shadow: inset 0px 1px 0 rgba(0,0,0,.075);
 }
 .left-border-none {
    border-left:none !important;
    box-shadow: inset 0px 1px 0 rgba(0,0,0,.075);
 }

By making the background of the input-group-addon transparent and making the left gradient of the input tag to zero the input will have a seamless appearance. Here is the customised output

Here is a jsbin example

This will solve the custom css problems of overlapping with labels, alignment while using input-lg and focus on tab issue.

Try this...

$('p').append('<span id="add_here">new-dynamic-text</span>');

OR if there is an existing span, do this.

$('p').children('span').text('new-dynamic-text');

DEMO

Try by changing X[:,3] to X.iloc[:,3] in label encoder

As Unwind points out f and g provide different default outputs.

Roughly speaking if you care more about the details of what comes after the decimal point I would do with f and if you want to scale for large numbers go with g. From some dusty memories f is very nice with small values if your printing tables of numbers as everything stays lined up but something like g is needed if you stand a change of your numbers getting large and your layout matters. e is more useful when your numbers tend to be very small or very large but never near ten.

An alternative is to specify the output format so that you get the same number of characters representing your number every time.

Sorry for the woolly answer but it is a subjective out put thing that only gets hard answers if the number of characters generated is important or the precision of the represented value.

This works for me...

Maybe try this:

            :controller => "car", 
            :action => "add_to_cart", 
            :car => car.attributes %>

But I'd really like to see where the car object is getting setup for this page (i.e., the rest of the view).

Here's a version without recursion:

def get_subclasses_gen(cls):

    def _subclasses(classes, seen):
        while True:
            subclasses = sum((x.__subclasses__() for x in classes), [])
            yield from classes
            yield from seen
            found = []
            if not subclasses:
                return

            classes = subclasses
            seen = found

    return _subclasses([cls], [])

This differs from other implementations in that it returns the original class. This is because it makes the code simpler and:

class Ham(object):
    pass

assert(issubclass(Ham, Ham)) # True

If get_subclasses_gen looks a bit weird that's because it was created by converting a tail-recursive implementation into a looping generator:

def get_subclasses(cls):

    def _subclasses(classes, seen):
        subclasses = sum(*(frozenset(x.__subclasses__()) for x in classes))
        found = classes + seen
        if not subclasses:
            return found

        return _subclasses(subclasses, found)

    return _subclasses([cls], [])

You can use the & operator on the Method instance of your method to convert the method to a block.

Example:

def foo(arg)
  p arg
end

def bar(&block)
  p 'bar'
  block.call('foo')
end

bar(&method(:foo))

More details at http://weblog.raganwald.com/2008/06/what-does-do-when-used-as-unary.html

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

It is correct like this:

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

or like

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

or even

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

You could also use to localStorage feature of HTML5 to store your test value and then access it at any other point in your website by using the localStorage.getItem() method. To see how this works you should look at the w3schools explanation or the explanation from the Opera Developer website. Hope this helps.

Mongoose's findById method casts the id parameter to the type of the model's _id field so that it can properly query for the matching doc. This is an ObjectId but "foo" is not a valid ObjectId so the cast fails.

This doesn't happen with 41224d776a326fb40f000001 because that string is a valid ObjectId.

One way to resolve this is to add a check prior to your findById call to see if id is a valid ObjectId or not like so:

if (id.match(/^[0-9a-fA-F]{24}$/)) {
  // Yes, it's a valid ObjectId, proceed with `findById` call.
}

Remove the comma?

select /*+USE_HASH( a b ) */ to_char(date, 'MM/DD/YYYY HH24:MI:SS') as LABEL,
ltrim(rtrim(substr(oled, 9, 16))) as VALUE
from rrfh a, rrf b
where ltrim(rtrim(substr(oled, 1, 9))) = 'stata kish' 
and a.xyz = b.xyz

Have a look at FROM

SELECTING from multiple tables You can include multiple tables in the FROM clause by listing the tables with a comma in between each table name

You must add an id that auto-increment for each row, after that you can delet the row by its id. so your table will have an unique id for each row and the id_user, id_product ecc...

I'd like to offer yet another solution. It's similar to the already proposed ones as it uses HTML-code in a JLabel, and registers a MouseListener on it, but it also displays a HandCursor when you move the mouse over the link, so the look&feel is just like what most users would expect. If browsing is not supported by the platform, no blue, underlined HTML-link is created that could mislead the user. Instead, the link is just presented as plain text. This could be combined with the SwingLink class proposed by @dimo414.

If you are using the LinearLayoutManager or Staggered GridLayoutManager, they each have a scrollToPositionWithOffset method that takes both the position and also the offset of the start of the item from the start of the RecyclerView, which seems like it would accomplish what you need (setting the offset to 0 should align with the top).

For instance:

I am using git push <remote-name> tag <tag-name> to ensure that I am pushing a tag. I use it like: git push origin tag v1.0.1. This pattern is based upon the documentation (man git-push):

OPTIONS
   ...
   <refspec>...
       ...
       tag <tag> means the same as refs/tags/<tag>:refs/tags/<tag>.

I was facing the same problem when import projects into IntelliJ.

for in my case first, check SDK details and check you have configured JDK correctly or not.

Go to File-> Project Structure-> platform Settings-> SDKs

Check your JDK is correct or not.

Next, I Removed project from IntelliJ and delete all IntelliJ and IDE related files and folder from the project folder (.idea, .settings, .classpath, dependency-reduced-pom). Also, delete the target folder and re-import the project.

The above solution worked in my case.

Applying the recursive function on numpy arrays will be faster than the current answer.

df = pd.DataFrame(np.repeat(np.arange(2, 6),3).reshape(4,3), columns=['A', 'B', 'D'])
new = [df.D.values[0]]
for i in range(1, len(df.index)):
    new.append(new[i-1]*df.A.values[i]+df.B.values[i])
df['C'] = new

Output

      A  B  D    C
   0  1  1  1    1
   1  2  2  2    4
   2  3  3  3   15
   3  4  4  4   64
   4  5  5  5  325

It works if id value and name value are different:

<input type="password" class="form-control"name="password" id="mainpassword">
password: {     required: true,     } , 
cpassword: {required: true, equalTo: '#mainpassword' },

WARNING: setting this value too high may cause your system to experience a significant hiccup. The higher the value you set, the more virtual memory is allocated to the screen process when initiating the screen session. I set my ~/.screenrc to "defscrollback 123456789" and when I initiated a screen, my entire system froze up for a good 10 minutes before coming back to the point that I was able to kill the screen process (which was consuming 16.6GB of VIRT mem by then).

I usually find that ProgrammableWeb is a good place to go when looking for APIs.

Try this:

excelBook.Close(0); 
excelApp.Quit();

When closing the work-book, you have three optional parameters:

Workbook.close SaveChanges, filename, routeworkbook 

Workbook.Close(false) or if you are doing late binding, it sometimes is easier to use zero Workbook.Close(0) That is how I've done it when automating closing of workbooks.

Also I went and looked up the documentation for it, and found it here: Excel Workbook Close

As of docker-compose version 3 and later, you can just use the hostname key:

version: '3'
services:
  dns:
    hostname: 'your-name'

A quick fix where nothing else works:

const a.b = 5 // error

const a['b'] = 5 // error if ts-lint rule no-string-literal is enabled

const B = 'b'
const a[B] = 5 // always works

Not good practice but provides a solution without needing to turn off no-string-literal

Install PAR::Packer from CPAN (it is free) and use pp utility.

Hierarchy of log4j logging levels are as follows in Highest to Lowest order :

• TRACE
• DEBUG
• INFO
• WARN
• ERROR
• FATAL
• OFF

TRACE log level provides highest logging which would be helpful to troubleshoot issues. DEBUG log level is also very useful to trouble shoot the issues.

You can also refer this link for more information about log levels : https://logging.apache.org/log4j/2.0/manual/architecture.html

...5+ years later, I strongly suggest using date-fns instead

import endOfDayfrom 'date-fns/endOfDay'
import startOfDay from 'date-fns/startOfDay'

MyModel.find({
  createdAt: {
    $gte: startOfDay(new Date()),
    $lte: endOfDay(new Date())
  }
})

For those of us using Moment.js

const moment = require('moment')

const today = moment().startOf('day')

MyModel.find({
  createdAt: {
    $gte: today.toDate(),
    $lte: moment(today).endOf('day').toDate()
  }
})

Important: all moments are mutable!

tomorrow = today.add(1, 'days') does not work since it also mutates today. Calling moment(today) solves that problem by implicitly cloning today.

You can find the codes in the DB2 Information Center. Here's a definition of the -302 from the z/OS Information Center:

THE VALUE OF INPUT VARIABLE OR PARAMETER NUMBER position-number IS INVALID OR TOO LARGE FOR THE TARGET COLUMN OR THE TARGET VALUE

On Linux/Unix/Windows DB2, you'll look under SQL Messages to find your error message. If the code is positive, you'll look for SQLxxxxW, if it's negative, you'll look for SQLxxxxN, where xxxx is the code you're looking up.

if you have added a new line, Make sure you have added next line syntax in previous line. typically if "\" is missing in your previous line of changes, you will get this error.

If you are planing to use the same image for retina and non-retina screen then here is the solution. Say that you have a image of 200x200 and have two icons in top row and two icon in bottom row. So, it's four quadrants.

.sprite-of-icons {
  background: url("../images/icons-in-four-quad-of-200by200.png") no-repeat;
  background-size: 100px 100px /* Scale it down to 50% rather using 200x200 */
}

.sp-logo-1 { background-position: 0 0; }

/* Reduce positioning of the icons down to 50% rather using -50px */
.sp-logo-2 { background-position: -25px 0 }
.sp-logo-3 { background-position: 0 -25px }
.sp-logo-3 { background-position: -25px -25px }

Scaling and positioning of the sprite icons to 50% than actual value, you can get the expected result.

It could be some un-initialized function pointer, in particular if you have corrupted memory (then the bogus vtable of C++ bad pointers to invalid objects might give that).

BTW gdb watchpoints & tracepoints, and also valgrind might be useful (if available) to debug such issues. Or some address sanitizer.

Header fields are not copied to subsequent requests. You should use either cookie for this (addCookie method) or store "REMOTE_USER" in session (which you can obtain with getSession method).

The following steps will help you to sort your problem out.

Steps: developer_identity.cer <= download from Apple mykey.p12 <= Your private key

Commands to follow:

    openssl x509 -in developer_identity.cer -inform DER -out developer_identity.pem -outform PEM

    openssl pkcs12 -nocerts -in mykey.p12 -out mykey.pem

    openssl pkcs12 -export -inkey mykey.pem -in developer_identity.pem -out iphone_dev.p12

Final p12 that we will require is iphone_dev.p12 file and the passphrase.

use this file as your p12 and then try. This indeed is the solution.:)

You could use the video-out and capture that somehow with a firewire or sumthing.. The class MPTVOutWindow can help you out! Here's a nice sample of that!

use process monitor and search for name not found log for tnsnames.ora file.

check your environment variables. if not valid than uninstall all oracle client and reinstall.

For me, .htaccess was redirecting when mod_rewrite wasn't installed. Install mod_rewite and all is fine.

Specifically:

<IfModule !mod_rewrite.c>
  ErrorDocument 404 /index.php
</Ifmodule>

was executing.

I find this lecture very valuable https://vimeo.com/190275665, in point 3 it summarizes these generators and also gives some performance analysis and guideline one when you use each one.

Try this:

this.TextBox3.Text = String.Format("{0: MM.dd.yyyy}",DateTime.Now);

Embarrassing to say it, but when I had this problem, it was simply a mistake that I was closing the connection before I read all the data. In cases with small strings being returned, it worked, but that was probably due to the whole response was buffered, before I closed it.

In cases of longer amounts of text being returned, the exception was thrown, since more then a buffer was coming back.

You might check for this oversight. Remember opening a URL is like a file, be sure to close it (release the connection) once it has been fully read.

You can also place the SQL statement in a separate file, action.sql, and load it in the .py file with:

with open('action.sql') as f:
   query = f.read()

So the SQL statements will be separated from the Python code. If there are parameters in the SQL statement which needs to be filled from Python, you can use string formatting (like %s or {field}).

You can set the following environment variable:

PIP_TARGET=/path/to/pip/dir

https://pip.pypa.io/en/stable/user_guide/#environment-variables

For whatever it's worth now: here is yet another solution:

• create two divs within a display: inline-block
• in the first div, put a table with only the header (header table tabhead)
• in the 2nd div, put a table with header and data (data table / full table tabfull)
• use JavaScript, use setTimeout(() => {/*...*/}) to execute code after render / after filling the table with results from fetch
• measure the width of each th in the data table (using clientWidth)
• apply the same width to the counterpart in the header table
• set visibility of the header of the data table to hidden and set the margin top to -1 * height of data table thead pixels

With a few tweaks, this is the method to use (for brevity / simplicity, I used d3js, the same operations can be done using plain DOM):

setTimeout(() => { // pass one cycle
  d3.select('#tabfull')
    .style('margin-top', (-1 * d3.select('#tabscroll').select('thead').node().getBoundingClientRect().height) + 'px')
    .select('thead')
      .style('visibility', 'hidden');
  let widths=[]; // really rely on COMPUTED values
  d3.select('#tabfull').select('thead').selectAll('th')
    .each((n, i, nd) => widths.push(nd[i].clientWidth));
  d3.select('#tabhead').select('thead').selectAll('th')
    .each((n, i, nd) => d3.select(nd[i])
          .style('padding-right', 0)
          .style('padding-left', 0)
          .style('width', widths[i]+'px'));
})

Waiting on render cycle has the advantage of using the browser layout engine thoughout the process - for any type of header; it's not bound to special condition or cell content lengths being somehow similar. It also adjusts correctly for visible scrollbars (like on Windows)

I've put up a codepen with a full example here: https://codepen.io/sebredhh/pen/QmJvKy

I want to extend @theutz's answers - namely this line :

// services.AddAutoMapper(typeof(Startup));  // <-- newer automapper version uses this signature.

There is a bug (probably) in AutoMapper.Extensions.Microsoft.DependencyInjection version 3.2.0. (I'm using .NET Core 2.0)

This is tackled in this GitHub issue. If your classes inheriting AutoMapper's Profile class exist outside of assembly where you Startup class is they will probably not be registered if your AutoMapper injection looks like this:

services.AddAutoMapper();

unless you explicitly specify which assemblies to search AutoMapper profiles for.

It can be done like this in your Startup.ConfigureServices:

services.AddAutoMapper(<assembies> or <type_in_assemblies>);

where "assemblies" and "type_in_assemblies" point to the assembly where Profile classes in your application are specified. E.g:

services.AddAutoMapper(typeof(ProfileInOtherAssembly), typeof(ProfileInYetAnotherAssembly));

I suppose (and I put emphasis on this word) that due to following implementation of parameterless overload (source code from GitHub) :

public static IServiceCollection AddAutoMapper(this IServiceCollection services)
{
     return services.AddAutoMapper(null, AppDomain.CurrentDomain.GetAssemblies());
}

we rely on CLR having already JITed assembly containing AutoMapper profiles which might be or might not be true as they are only jitted when needed (more details in this StackOverflow question).

numpy.linspace() gives you a one-dimensional NumPy array. For example:

>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([  1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.])

Therefore:

for index,point in my_array

cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:

>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])

Now you can do this:

>>> for x, y in two_d:
    print(x, y)

1 2
4 5

you also can simply use

<script type="text/javascript">

   var data = [];

   @foreach (var r in Model.rows)
   {
       @:data.push([ @r.UnixTime * 1000, @r.Value ]);
   }
</script>

note @:

Try the below code:

[Route("/test")]
[HttpPost]
public async Task Test()
{
   using (var reader = new StreamReader(Request.Body, Encoding.UTF8))
   {
      var textFromBody = await reader.ReadToEndAsync();                    
   }            
}

The algorithm you are using, "AES", is a shorthand for "AES/ECB/NoPadding". What this means is that you are using the AES algorithm with 128-bit key size and block size, with the ECB mode of operation and no padding.

In other words: you are only able to encrypt data in blocks of 128 bits or 16 bytes. That's why you are getting that IllegalBlockSizeException exception.

If you want to encrypt data in sizes that are not multiple of 16 bytes, you are either going to have to use some kind of padding, or a cipher-stream. For instance, you could use CBC mode (a mode of operation that effectively transforms a block cipher into a stream cipher) by specifying "AES/CBC/NoPadding" as the algorithm, or PKCS5 padding by specifying "AES/ECB/PKCS5", which will automatically add some bytes at the end of your data in a very specific format to make the size of the ciphertext multiple of 16 bytes, and in a way that the decryption algorithm will understand that it has to ignore some data.

In any case, I strongly suggest that you stop right now what you are doing and go study some very introductory material on cryptography. For instance, check Crypto I on Coursera. You should understand very well the implications of choosing one mode or another, what are their strengths and, most importantly, their weaknesses. Without this knowledge, it is very easy to build systems which are very easy to break.

Update: based on your comments on the question, don't ever encrypt passwords when storing them at a database!!!!! You should never, ever do this. You must HASH the passwords, properly salted, which is completely different from encrypting. Really, please, don't do what you are trying to do... By encrypting the passwords, they can be decrypted. What this means is that you, as the database manager and who knows the secret key, you will be able to read every password stored in your database. Either you knew this and are doing something very, very bad, or you didn't know this, and should get shocked and stop it.

Come on Google, you guys are smarter than the API Credential page lets on. (I know because I have two sons working there.)

The list of "referrers" is far pickier than it lets on. (Of course, it should be more forgiving.) Here are some rules that took me hours to discover:

• The order in the list is important. Moving your URL up in the list may make it work.
• "http://" prefix is required.
• Even "localhost" needs it: "http://localhost/foo/bar.html"
• A trailing * as a wildcard seems to work as if it is a string compare.
• Even with "http://localhost/foo/bar.html", "http://localhost/foo/bar.html?arg=1" will not work. (Will a wildcard help?)
• For both prod dev, have (at least) two rows: "http://localhost/foo/bar.html" and "http://my.site.com/foo/bar.html"
• A port number (8085? 4000?) does not seem to be necessary.

There are probably other rules, but this is a tedious guessing game.

The string class's Replace method can also be used to remove multiple characters from a string:

Dim newstring As String
newstring = oldstring.Replace(",", "").Replace(";", "")

This is the most correct answer for IE and Chrome::

javascript=>

var element = document.getElementById('xxxx');
var evt = document.createEvent('HTMLEvents');
evt.initEvent('change', false, true);
element.dispatchEvent(evt);

It's a tree, so recursion is your friend: start with the parent directory and call the method to get an array of child Files. Iterate through the child array. If the current value is a directory, pass it to a recursive call of your method. If not, process the leaf file appropriately.

As far as I know, an input element may not have a href attribute, which is where Fancybox gets its information about the content. The following code uses an a element instead of the input element. Also, this is what I would call the "standard way".

That's it! Now you can access it in PHP:

<?php $myArray = $_REQUEST['activitiesArray']; ?>

I couldn't figure out what exactly you meant by byte String, but here are some conversions from byte to String and vice versa, of course there is a lot more on the official documentations

Integer intValue = 149;

The corresponding byte value is:

Byte byteValue = intValue.byteValue(); // this will convert the rightmost byte of the intValue to byte, because Byte is an 8 bit object and Integer is at least 16 bit, and it will give you a signed number in this case -107

get the integer value back from a Byte variable:

Integer anInt = byteValue.intValue(); // This will convert the byteValue variable to a signed Integer

From Byte and Integer to hex String:
This is the way I do it:

Integer anInt = 149
Byte aByte = anInt.byteValue();

String hexFromInt = "".format("0x%x", anInt); // This will output 0x95
String hexFromByte = "".format("0x%x", aByte); // This will output 0x95

Converting an array of bytes to a hex string:
As far as I know there is no simple function to convert all the elements inside an array of some Object to elements of another Object, So you have to do it yourself. You can use the following functions:

From byte[] to String:

    public static String byteArrayToHexString(byte[] byteArray){
        String hexString = "";

        for(int i = 0; i < byteArray.length; i++){
            String thisByte = "".format("%x", byteArray[i]);
            hexString += thisByte;
        }

        return hexString;
    }

And from hex string to byte[]:

public static byte[] hexStringToByteArray(String hexString){
    byte[] bytes = new byte[hexString.length() / 2];

    for(int i = 0; i < hexString.length(); i += 2){
        String sub = hexString.substring(i, i + 2);
        Integer intVal = Integer.parseInt(sub, 16);
        bytes[i / 2] = intVal.byteValue();
        String hex = "".format("0x%x", bytes[i / 2]);
    }

    return bytes;
}  

It is too late but I hope this could help some others ;)

Here is creating a ComboBox adding a listener for item selection change:

JComboBox comboBox = new JComboBox();

comboBox.setBounds(84, 45, 150, 20);
contentPane.add(comboBox);

comboBox_1.setBounds(84, 97, 150, 20);
contentPane.add(comboBox_1);
comboBox.addItemListener(new ItemListener() {
    public void itemStateChanged(ItemEvent arg0) {
        //Do Something

check the official example. X,Y and Z are indeed 2d arrays, numpy.meshgrid() is a simple way to get 2d x,y mesh out of 1d x and y values.

here's pythonic way to convert your 3-tuples to 3 1d arrays.

data = [(1,2,3), (10,20,30), (11, 22, 33), (110, 220, 330)]
X,Y,Z = zip(*data)
In [7]: X
Out[7]: (1, 10, 11, 110)
In [8]: Y
Out[8]: (2, 20, 22, 220)
In [9]: Z
Out[9]: (3, 30, 33, 330)

Here's mtaplotlib delaunay triangulation (interpolation), it converts 1d x,y,z into something compliant (?):

There are a few steps to see the tables in an SQLite database:

1. List the tables in your database:

   .tables
   

2. List how the table looks:

   .schema tablename
   

3. Print the entire table:

   SELECT * FROM tablename;
   

4. List all of the available SQLite prompt commands:

   .help
   

re.match attempts to match a pattern at the beginning of the string. re.search attempts to match the pattern throughout the string until it finds a match.

Greedy Quantifiers are like the IRS/ATO

If it’s there, they’ll take it all.

The IRS matches with this regex: .*

$50,000

This will match everything!

See here for an example: Greedy-example

Non-greedy quantifiers - they take as little as they can

If I ask for a tax refund, the IRS sudden becomes non-greedy, and they use this quantifier:

(.{2,5}?)([0-9]*) against this input: $50,000

The first group is non-needy and only matches $5 – so I get a $5 refund against the $50,000 input. They're non-greedy. They take as little as possible.

See here: Non-greedy-example.

Why bother?

It becomes important if you are trying to match certain parts of an expression. Sometimes you don't want to match everything.

Hopefully that analogy will help you remember!

        var gmtHours = Math.floor(gmtOffSet / 60);
        var GMTMin = Math.abs(gmtOffSet % 60);
        var dot = ".";
        var retVal = "" + gmtHours + dot + GMTMin;
       document.getElementById('<%= offSet.ClientID%>').value = retVal;

      }
  </script>

As other comments here pointed out, you'll need to uncomment disable_overscan=1 in /boot/config.txt

if you are using NOOBS (this is what im using), you'll find in the end of the file a set of default settings that has disable_overscan=0 attribute. you'll need to change its value to 1, and re-boot.

Use + plus sign (Match one or more of the previous items),

var regexp = /^\S+$/

Worksheets("Sheet1").Delete
Worksheets("Sheet2").Delete

I have slightly modified the accepted answer by handling value types. I came across this when trying to do the following and because GetProperties() is zero length for value types I was getting an empty dataset. I know this is not the use case for the OP but thought I'd post this change in case anyone else came across the same thing.

Enumerable.Range(1, 10).ToList().ToDataSet();

public static DataSet ToDataSet<T>(this IList<T> list)
{
    var elementType = typeof(T);
    var ds = new DataSet();
    var t = new DataTable();
    ds.Tables.Add(t);

    if (elementType.IsValueType)
    {
        var colType = Nullable.GetUnderlyingType(elementType) ?? elementType;
        t.Columns.Add(elementType.Name, colType);

    } else
    {
        //add a column to table for each public property on T
        foreach (var propInfo in elementType.GetProperties())
        {
            var colType = Nullable.GetUnderlyingType(propInfo.PropertyType) ?? propInfo.PropertyType;
            t.Columns.Add(propInfo.Name, colType);
        }
    }

    //go through each property on T and add each value to the table
    foreach (var item in list)
    {
        var row = t.NewRow();

        if (elementType.IsValueType)
        {
            row[elementType.Name] = item;
        }
        else
        {
            foreach (var propInfo in elementType.GetProperties())
            {
                row[propInfo.Name] = propInfo.GetValue(item, null) ?? DBNull.Value;
            }
        }
        t.Rows.Add(row);
    }

    return ds;
}

If you use sql server Management studio go to Tools >> Options >> Designers and uncheck “Prevent Saving changes that require table re-creation” It works with me

The following worked for me taken from the official Mozilla documentation Error.

function NotImplementedError(message) {
    var instance = new Error(message);
    instance.name = 'NotImplementedError';

    Object.setPrototypeOf(instance, Object.getPrototypeOf(this));
    if (Error.captureStackTrace) {
        Error.captureStackTrace(instance, NotImplementedError);
    }
    return instance;
}

NotImplementedError.prototype = Object.create(Error.prototype, {
    constructor: {
        value: Error,
        enumerable: false,
        writable: true,
        configurable: true
    }
});

If you get to the point where all the mentioned solutions don't work (as it got for me), do this:

• Create two tables. One for the header and another for the body
• Give the two tables different parent containers/divs
• Style the second table's div to allow vertical scroll of its contents.

Like this, in your HTML

<div class="table-header-class">
    <table>
       <thead>
          <tr>
            <th>Ava</th>
            <th>Alexis</th>
            <th>Mcclure</th>
          </tr>
       </thead>
    </table>
</div>
<div class="table-content-class">
   <table>
       <tbody>
          <tr>
            <td>I am the boss</td>
            <td>No, da-da is not the boss!</td>
            <td>Alexis, I am the boss, right?</td>
          </tr>
       </tbody>
    </table>
</div>

Then style the second table's parent to allow vertical scroll, in your CSS

    .table-content-class {
        overflow-y: scroll;    // use auto; or scroll; to allow vertical scrolling; 
        overflow-x: hidden;    // disable horizontal scroll 
    }

I faced the same problem, I added android support design dependencies to the app level build.gradle

Add following:

implementation 'com.android.support:design:27.1.0'

in build.gradle. Now its working for me.

If you are uploading your files through GIT from your local machine then you can use the same command you are using in your local machine while you are connected to your live server using BASH or something like.You can use this as like you use locally.

php artisan cache:clear

php artisan route:cache

It should work.

foreach (DataTable table in dataSet.Tables)
{
    foreach (DataRow row in table.Rows)
    {
        foreach (object item in row.ItemArray)
        {
            // read item
        }
    }
}

Or, if you need the column info:

foreach (DataTable table in dataSet.Tables)
{
    foreach (DataRow row in table.Rows)
    {
        foreach (DataColumn column in table.Columns)
        {
            object item = row[column];
            // read column and item
        }
    }
}

For me, when using IntelliJ IDEA, this error arose because I had the Java SDK, rather than an Android SDK, set at the Project level.

My fix:

• IntelliJ > File > Project Structure ...
• Project > Project SDK > [Select] 'Android API 19 Platform (java version "1.7.0_40")'

I'm on:

• IntelliJ IDEA: 13.1.3
• Gradle: 1.10
• Android Plugin for Gradle: 0.9.+

I tried the code by @alex-martelli but found some discrepancies

python -mtimeit -s "xs=range(123456)" "map(hex, xs)"
1000000 loops, best of 5: 218 nsec per loop
python -mtimeit -s "xs=range(123456)" "[hex(x) for x in xs]"
10 loops, best of 5: 19.4 msec per loop

map takes the same amount of time even for very large ranges while using list comprehension takes a lot of time as is evident from my code. So apart from being considered "unpythonic", I have not faced any performance issues relating to usage of map.

Use switch!

I hate to maintain if-else-blocks! Have a test:

Your best option here, is to use the Query String to 'send' the value.

how to get query string value using javascript

• So page 1 redirects to page2.html?someValue=ABC
• Page 2 can then read the query string and specifically the key 'someValue'

If this is anything more than a learning exercise you may want to consider the security implications of this though.

Global variables wont help you here as once the page is re-loaded they are destroyed.

Yes, tasks waiting for IO are blocked, and other tasks get executed. Selecting the next task is done by the Linux scheduler.

There are a couple of ways to solve this problem

Pyinx - a pretty lightweight tool that allows you to call Python from withing the excel process space http://code.google.com/p/pyinex/

I've used this one a few years ago (back when it was being actively developed) and it worked quite well

If you don't mind paying, this looks pretty good

https://datanitro.com/product.html

I've never used it though

Though if you are already writting in Python, maybe you could drop excel entirely and do everything in pure python? It's a lot easier to maintain one code base (python) rather than 2 (python + whatever excel overlay you have).

If you really have to output your data into excel there are even some pretty good tools for that in Python. If that may work better let me know and I'll get the links.

In case of your jdk version less than 1.5, following option can be used.

    int iTest = 2;
    StringBuffer sTest = new StringBuffer("000000"); //if the string size is 6
    sTest.append(String.valueOf(iTest));
    System.out.println(sTest.substring(sTest.length()-6, sTest.length()));

If you're using jQuery and want to keep using indexOf without worrying about compatibility issues, you can do this :

if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function(val) {
        return jQuery.inArray(val, this);
    };
}

This is helpful when you want to keep using indexOf but provide a fallback when it's not available.

With recent version of Pandas, you can do df.N.hist(by=df.Letter)

Just like with the solutions above, the axes will be different for each subplot. I have not solved that one yet.

Assuming your json object from your GET request looks like the one you posted above simply do:

let list: string[] = [];

json.Results.forEach(element => {
    list.push(element.Id);
});

Or am I missing something that prevents you from doing it this way?

Edit: In Bootstrap 4, native classes can produce full-height columns (DEMO) because they changed their grid system to flexbox. (Read on for Bootstrap 3)

Bootply demo / Codepen

Markup:

<header>Header</header>
<div class="container">
    <div class="row">
        <div class="col-md-3 no-float">Navigation</div>
        <div class="col-md-9 no-float">Content</div>
    </div>
</div>

(Relevant) CSS

html,body,.container {
    height:100%;
}
.container {
    display:table;
    width: 100%;
    margin-top: -50px;
    padding: 50px 0 0 0; /*set left/right padding according to needs*/
    box-sizing: border-box;
}

.row {
    height: 100%;
    display: table-row;
}

.row .no-float {
  display: table-cell;
  float: none;
}

The above code will achieve full-height columns (due to the custom css-table properties which we added) and with ratio 1:3 (Navigation:Content) for medium screen widths and above - (due to bootstrap's default classes: col-md-3 and col-md-9)

NB:

1) In order not to mess up bootstrap's native column classes we add another class like no-float in the markup and only set display:table-cell and float:none on this class (as apposed to the column classes themselves).

2) If we only want to use the css-table code for a specific break-point (say medium screen widths and above) but for mobile screens we want to default back to the usual bootstrap behavior than we can wrap our custom CSS within a media query, say:

@media (min-width: 992px) {
  .row .no-float {
      display: table-cell;
      float: none;
  }
}

Codepen demo

Now, for smaller screens, the columns will behave like default bootstrap columns (each getting full width).

3) If the 1:3 ratio is necessary for all screen widths - then it's probably a better to remove bootstrap's col-md-* classes from the markup because that's not how they are meant to be used.

Codepen demo

Just window.location = "http://wherever.you.wanna.go.com/", or, for local links, window.location = "my_relative_link.html".

You can try it by typing it into your address bar as well, e.g. javascript: window.location = "http://www.google.com/".

Also note that the protocol part of the URL (http://) is not optional for absolute links; omitting it will make javascript assume a relative link.

I was able to get Font Awesome to work by using the all.min.css file.

Replace your jquery files with followings :

<script src="//code.jquery.com/jquery-1.11.3.min.js"></script> <script src="//code.jquery.com/jquery-migrate-1.2.1.min.js"></script>

Now you can do it with the GitHub Desktop application.

After launching the application

1. Click on the project containing the branch

2. Switch to the branch you would like to delete

   

3. From the "Branch" menu, select, "Unpublish...", to have the branch deleted from the GitHub servers.

   

4. From the "Branch" menu, select, 'Delete "branch_name"...', to have the branch deleted off of your local machine (AKA the machine you are currently working on)

   

Additional useful info:

You can provide several og:images, whatsapp will use the last one. This will help with the problem that e.g. facebook want 1.91:1 ratio and whatsapp 1:1

This topic is discussed at CProgramming.com:
https://www.cprogramming.com/compilingandlinking.html

Here is what the author there wrote:

Compiling isn't quite the same as creating an executable file! Instead, creating an executable is a multistage process divided into two components: compilation and linking. In reality, even if a program "compiles fine" it might not actually work because of errors during the linking phase. The total process of going from source code files to an executable might better be referred to as a build.

Compilation

Compilation refers to the processing of source code files (.c, .cc, or .cpp) and the creation of an 'object' file. This step doesn't create anything the user can actually run. Instead, the compiler merely produces the machine language instructions that correspond to the source code file that was compiled. For instance, if you compile (but don't link) three separate files, you will have three object files created as output, each with the name .o or .obj (the extension will depend on your compiler). Each of these files contains a translation of your source code file into a machine language file -- but you can't run them yet! You need to turn them into executables your operating system can use. That's where the linker comes in.

Linking

Linking refers to the creation of a single executable file from multiple object files. In this step, it is common that the linker will complain about undefined functions (commonly, main itself). During compilation, if the compiler could not find the definition for a particular function, it would just assume that the function was defined in another file. If this isn't the case, there's no way the compiler would know -- it doesn't look at the contents of more than one file at a time. The linker, on the other hand, may look at multiple files and try to find references for the functions that weren't mentioned.

You might ask why there are separate compilation and linking steps. First, it's probably easier to implement things that way. The compiler does its thing, and the linker does its thing -- by keeping the functions separate, the complexity of the program is reduced. Another (more obvious) advantage is that this allows the creation of large programs without having to redo the compilation step every time a file is changed. Instead, using so called "conditional compilation", it is necessary to compile only those source files that have changed; for the rest, the object files are sufficient input for the linker. Finally, this makes it simple to implement libraries of pre-compiled code: just create object files and link them just like any other object file. (The fact that each file is compiled separately from information contained in other files, incidentally, is called the "separate compilation model".)

To get the full benefits of condition compilation, it's probably easier to get a program to help you than to try and remember which files you've changed since you last compiled. (You could, of course, just recompile every file that has a timestamp greater than the timestamp of the corresponding object file.) If you're working with an integrated development environment (IDE) it may already take care of this for you. If you're using command line tools, there's a nifty utility called make that comes with most *nix distributions. Along with conditional compilation, it has several other nice features for programming, such as allowing different compilations of your program -- for instance, if you have a version producing verbose output for debugging.

Knowing the difference between the compilation phase and the link phase can make it easier to hunt for bugs. Compiler errors are usually syntactic in nature -- a missing semicolon, an extra parenthesis. Linking errors usually have to do with missing or multiple definitions. If you get an error that a function or variable is defined multiple times from the linker, that's a good indication that the error is that two of your source code files have the same function or variable.

Query below should help you achieve what you want.

select scountry, headofstate from data 
where data.scountry like 'a%'and ttlppl>=100000

You can change the hook to wipe everything clean.

# Danger! Wipes local data!

# Remove all local changes to tracked files
git reset --hard HEAD

# Remove all untracked files and directories
git clean -dfx

git pull ...

For complex select with ORDER BY I use the following:

SELECT * FROM (
    SELECT 'Column name #1', 'Column name #2', 'Column name ##'
    UNION ALL
    (
        // complex SELECT statement with WHERE, ORDER BY, GROUP BY etc.
    )
) resulting_set
INTO OUTFILE '/path/to/file';

You didn't explicitly state emacs, but since you've highlighted lots of editors...

In emacs, you can use rectangles for this, where a column is a rectangle of width 1.

To create a rectangle, mark the top-left and bottom-right of the rectangle (where the bottom-right mark is one to the right of the further right point included in the rectangle. You can then manipulate via:

C-x r k
Kill the text of the region-rectangle, saving its contents as the "last killed rectangle" (kill-rectangle).

C-x r d
Delete the text of the region-rectangle (delete-rectangle).

C-x r y
Yank the last killed rectangle with its upper left corner at point (yank-rectangle).

C-x r o
Insert blank space to fill the space of the region-rectangle (open-rectangle). This pushes the previous contents of the region-rectangle rightward.

M-x clear-rectangle
Clear the region-rectangle by replacing its contents with spaces.

M-x delete-whitespace-rectangle
Delete whitespace in each of the lines on the specified rectangle, starting from the left edge column of the rectangle.

C-x r t string RET
Replace rectangle contents with string on each line. (string-rectangle).

M-x string-insert-rectangle RET string RET
Insert string on each line of the rectangle.

i dont know if there is a function but this would do the job in case there is no exsiting one:

String s = "here are a bunch of words";

final StringBuilder result = new StringBuilder(s.length());
String[] words = s.split("\\s");
for(int i=0,l=words.length;i<l;++i) {
  if(i>0) result.append(" ");      
  result.append(Character.toUpperCase(words[i].charAt(0)))
        .append(words[i].substring(1));

}

Try

this.dataset.id

$("#list li").on('click', function() {_x000D_
  alert( this.dataset.id );_x000D_
});

<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script>_x000D_

The approved answer from @jbochi does not work for me. The str() function call raises an exception because it cannot encode the non-ascii characters in the BeautifulSoup element. Here is a more succinct way to filter the example web page to visible text.

html = open('21storm.html').read()
soup = BeautifulSoup(html)
[s.extract() for s in soup(['style', 'script', '[document]', 'head', 'title'])]
visible_text = soup.getText()

Based on William McBrine's answer, here is a solution for fixed-length strings which is 9% faster for my use case:

import itertools
import struct
def make_strxor(size):
    def strxor(a, b, izip=itertools.izip, pack=struct.pack, unpack=struct.unpack, fmt='%dB' % size):
        return pack(fmt, *(a ^ b for a, b in izip(unpack(fmt, a), unpack(fmt, b))))
    return strxor
strxor_3 = make_strxor(3)
print repr(strxor_3('foo', 'bar'))

Within Crystal, you can do it by creating a formula that uses the ToNumber function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:

If NumericText ({field}) then ToNumber ({field}) else 0

Alternatively, you might find it easier to convert the field's datatype within the query used in the report.

Using cygwin bash to do the chopping

  :: e.g. FILE=basename.mp4 => FILE_NO_EXT=basename
  set FILE=%1
  for /f "delims=" %%a in ('bash -c "FILE=%FILE%; echo ${FILE/.*/}" ') do set FILE_NO_EXT=%%a

if you have only one xml in your table, you can convert it in 2 steps:

CREATE TABLE Batches( 
   BatchID int,
   RawXml xml 
)

declare @xml xml=(select top 1 RawXml from @Batches)

SELECT  --b.BatchID,
        x.XmlCol.value('(ReportHeader/OrganizationReportReferenceIdentifier)[1]','VARCHAR(100)') AS OrganizationReportReferenceIdentifier,
        x.XmlCol.value('(ReportHeader/OrganizationNumber)[1]','VARCHAR(100)') AS OrganizationNumber
FROM    @xml.nodes('/CasinoDisbursementReportXmlFile/CasinoDisbursementReport') x(XmlCol)

And now for some clever shell programming.

There is a cost with this solution, but at least it is based on everyday iteration and recursion. This can be converted to bash by paying careful attention to the typeset commands and converting them to declare or local where appropriate.

Discussion

When killing a process, one must deal with the realty that it could be a parent to many children, and that each child could be the parent of even more children, and on, and on, an on.

What to do?

If only there was a function to test if a process had children, and another function to return the child PIDs of a parent process.

Then, the game would be much simpler, because you could create a loop to iterate over a list of PIDs, checking each one for children before killing it. If there are no children, just kill the process. If there are children, call the driving function recursively and pass it the results of a function that gets the PIDs of a parent's children.

The base case action (process does not have children).

#!/bin/ksh

function killProcess ()
{
    typeset -r PID=$1

    if [[ ! isProcess $PID ]]
    then
        echo -e "Process $PID cannot be terminated because it does not exist.\n" 1>&2
        return 1
    elif [[ kill -s TERM $PID ]] && [[ ! isProcess $PID ]]
    then
        echo -e "Process $PID was terminated.\n" 1>&2
        return 0
    elif kill -s KILL $PID
        echo -e "Process $PID killed with SIGKILL (9) signal. No time to clean up potential files.\n" 1>&2
        return 0
    elif isZombie $PID
    then
        echo -e "Process $PID in the zombie status.\n" 1>&2 
        return 2
    else
        echo -e "Process $PID is alive. SIGTERM and SIGKILL had no effect. It is not a zombie.\n" 1>&2
    fi

    return 3
}

function attemptToKillPid ()
{
    typeset -r PID=$1

    if killProcess $PID
    then 
        return 0
    fi

    ppid=$(getParentPid $pid)
    echo -e "Process $pid of parent $ppid was not able to be killed.\n" 1>&2
    return 1
}

The general case action (process has children).

function killPidFamily ()
{
    typeset -r PROCESSES=$*
    typeset -ir NUM_PROCESSES_TO_KILL=$(countLines $PROCESSES)
    typeset -i numKilledProcesses=0
    typeset ppid

    for pid in $PROCESSES
    do
        pid=$(trim $pid)

        if ! hasChildPids $pid
        then
            attemptToKillPid $pid && (( numKilledProcesses++ ))
        else
            killPidFamily $(getChildPids $pid) && attemptToKillPid $pid && (( numKilledProcesses++ ))
        fi
    done

    (( numKilledProcesses == NUM_PROCESSES_TO_KILL ))
    return $?
}

Library of supporting functions.

#!/bin/ksh

function trim ()
{
    echo -n "$1" | tr -d [:space:]
}

function countLines ()
{
    typeset -r $LIST=$*
    trim $(echo $LIST | wc -l | awk {'print $1'})
}

function getProcesses ()
{
    # NOTE: -o pgid below would be $4 in awk.

    ps -e -o comm,pid,ppid,pgid,user,ruid,euid,group,rgid,egid,etime,etimes,stat --no-headers
}

function getProcess ()
{
   typeset -r PID=$1
   ps -p $PID -o comm,pid,ppid,pgid,user,ruid,euid,group,rgid,egid,etime,etimes,stat --no-headers
}

function isProcess ()
{
    typeset -r PID=$1

    ps -p $PID -o pid --no-headers 1>&2
    return $?
}

function getProcessStatus ()
{
    typeset -r PID=$1
    trim $(ps -p $PID -o stat --no-headers)
}

function isZombie ()
{
    typeset -r PID=$1
    typeset processStatus

    processStatus=$(getProcessStatus $PID)

    [[ "$processStatus" == "Z" ]]
    return $?
}

function hasChildPids ()
{
    typeset -r PPID=$1
    echo $(getProcesses) | awk '{print $3}' | sort -n | uniq | grep "^${PPID}$"
    return $?
}

function getChildPids ()
{
    typeset -r PPID=$1
    echo $(getProcesses) | awk '{print $2, $3}' | sort -k 2 | awk "\$2 == $PPID {print \$1}" | sort -n
}

function getParentPid ()
{
    typeset -r PID=$1
    trim $(echo $(getProcess $PID) | awk '{print $3}')
}

In this way, you know for sure that the process tree is being destroyed from the branches, moving up to the root. This helps avoid the potential of creating zombies and other undesirable situations.

Now, that you have seen the most expensive way to do this (killing one process at a time), investigate how you could alter this solution to use the PGID (process group ID). The getProcesses () function already prints the PGID ($4 in awk), so learn how to use it, or don't.

All in All, after reading this all page and other ones and a lot of documentation. Here's the summary:

• For first/last child: Safe to use now (Supported by all modern browsers)
• :nth-child() Also safe to use now (Supported by all modern browsers). But be careful it even counts siblings! So, the following won't work properly:

/* This should select the first 2 element with class display_class
* but it will NOT WORK Because the nth-child count even siblings 
* including the first div skip_class
*/
.display_class:nth-child(-n+2){ 
    background-color:green; 
}

<ul>
   <li class="skip_class">test 1</li>
   <li class="display_class">test 2 should be in green</li>
   <li class="display_class">test 3 should be in green</li>
   <li class="display_class">test 4</li>
 </ul>

Currently, there is a selector :nth-child(-n+2 of .foo) that supports selection by class but not supported by modern browsers so not useful.

So, that leaves us with Javascript solution (we'll fix the example above):

// Here we'll go through the elements with the targeted class
// and add our classmodifer to only the first 2 elements!


[...document.querySelectorAll('.display_class')].forEach((element,index) => {
  if (index < 2) element.classList.add('display_class--green');
});

.display_class--green {
    background-color:green;
}

<ul>
   <li class="skip_class">test 1</li>
   <li class="display_class">test 2 should be in green</li>
   <li class="display_class">test 3 should be in green</li>
   <li class="display_class">test 4</li>
 </ul>
