ssh user@machine 'bash -s' < local_script.sh

or you can just

 ssh user@machine "remote command to run" 

You could just declare a DBMS_SQL.VARCHAR2_TABLE to hold an in-memory variable length array indexed by a BINARY_INTEGER:

DECLARE
   name_array dbms_sql.varchar2_table;
BEGIN
   name_array(1) := 'Tim';
   name_array(2) := 'Daisy';
   name_array(3) := 'Mike';
   name_array(4) := 'Marsha';
   --
   FOR i IN name_array.FIRST .. name_array.LAST
   LOOP
      -- Do something
   END LOOP;
END;

You could use an associative array (used to be called PL/SQL tables) as they are an in-memory array.

DECLARE
   TYPE employee_arraytype IS TABLE OF employee%ROWTYPE
        INDEX BY PLS_INTEGER;
   employee_array employee_arraytype;
BEGIN
   SELECT *
     BULK COLLECT INTO employee_array
     FROM employee
    WHERE department = 10;
   --
   FOR i IN employee_array.FIRST .. employee_array.LAST
   LOOP
      -- Do something
   END LOOP;
END;

The associative array can hold any make up of record types.

Hope it helps, Ollie.

The documentation says that there only one context variable, form.

If you're having trouble with login (which is common), the documentation says there are three context variables:

• form: A Form object representing the login form. See the forms documentation for more on Form objects.
• next: The URL to redirect to after successful login. This may contain a query string, too.
• site_name: The name of the current Site, according to the SITE_ID setting.

What about overriding the method with

void f(int value)
{
  f((byte)value);
}

this will allow for f(0)

This has always worked for me:

type Props = {
  children: JSX.Element;
};

Found the list in a similar question, previously on StackOverflow:

Hash Table - used for fast data lookup - symbol table for compilers, database indexing, caches,Unique data representation.

Trie - dictionary, such as one found on a mobile telephone for autocompletion and spell-checking.

Suffix tree - fast full text searches used in most word processors.

Stack - undo\redo operation in word processors, Expression evaluation and syntax parsing, many virtual machines like JVM are stack oriented.

Queues - Transport and operations research where various entities are stored and held to be processed later ie the queue performs the function of a buffer.

Priority queues - process scheduling in the kernel

Trees - Parsers, Filesystem

Radix tree - IP routing table

BSP tree - 3D computer graphics

Graphs - Connections/relations in social networking sites, Routing ,networks of communication, data organization etc.

Before applying WORKDIR. Here the WORKDIR is at the wrong place and is not used wisely.

FROM microsoft/aspnetcore:2
COPY --from=build-env /publish /publish
WORKDIR /publish
ENTRYPOINT ["dotnet", "/publish/api.dll"]

We corrected the above code to put WORKDIR at the right location and optimised the following statements by removing /Publish

FROM microsoft/aspnetcore:2
WORKDIR /publish
COPY --from=build-env /publish .
ENTRYPOINT ["dotnet", "api.dll"]

So it acts like a cd and sets the tone for the upcoming statements.

Typescript is (a superset of) javascript, so you just use JSON.parse as you would in javascript:

let obj = JSON.parse(jsonString);

Only that in typescript you can have a type to the resulting object:

interface MyObj {
    myString: string;
    myNumber: number;
}

let obj: MyObj = JSON.parse('{ "myString": "string", "myNumber": 4 }');
console.log(obj.myString);
console.log(obj.myNumber);

I got into this state recently. After resolving conflicts during a rebase, I committed my changes, rather than running git rebase --continue. This yields the same messages you saw when you ran your git status and git rebase --continue commands. I resolved the issue by running git rebase --abort, and then re-running the rebase. One could likely also skip the rebase, but I wasn't sure what state that would leave me in.

$ git rebase --continue
Applying: <commit message>
No changes - did you forget to use 'git add'?
If there is nothing left to stage, chances are that something else
already introduced the same changes; you might want to skip this patch.

When you have resolved this problem, run "git rebase --continue".
If you prefer to skip this patch, run "git rebase --skip" instead.
To check out the original branch and stop rebasing, run "git rebase --abort".

$ git status
rebase in progress; onto 4df0775
You are currently rebasing branch '<local-branch-name>' on '4df0775'.
  (all conflicts fixed: run "git rebase --continue")

nothing to commit, working directory clean

A simple solution using importlib instead of the imp package (tested for Python 2.7, although it should work for Python 3 too):

import importlib

dirname, basename = os.path.split(pyfilepath) # pyfilepath: '/my/path/mymodule.py'
sys.path.append(dirname) # only directories should be added to PYTHONPATH
module_name = os.path.splitext(basename)[0] # '/my/path/mymodule.py' --> 'mymodule'
module = importlib.import_module(module_name) # name space of defined module (otherwise we would literally look for "module_name")

Now you can directly use the namespace of the imported module, like this:

a = module.myvar
b = module.myfunc(a)

The advantage of this solution is that we don't even need to know the actual name of the module we would like to import, in order to use it in our code. This is useful, e.g. in case the path of the module is a configurable argument.

You can use the :not filter selector:

$('foo:not(".someClass")')

Or not() method:

$('foo').not(".someClass")

More Info:

• http://api.jquery.com/not-selector/
• http://api.jquery.com/not/

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.

Once you read what What Every Computer Scientist Should Know About Floating-Point Arithmetic you could use the .toFixed() function:

var result = parseFloat('2.3') + parseFloat('2.4');
alert(result.toFixed(2));?

Just adding a parameter like the below worked for me.

cursor=conn.cursor(dictionary=True)

I hope this would be helpful either.

Note about tag of tag (tagging a tag), which is at the origin of your issue, as Charles Bailey correctly pointed out in the comment:

Make sure you study this thread, as overriding a signed tag is not as easy:

• if you already pushed a tag, the git tag man page seriously advised against a simple git tag -f B to replace a tag name "A"

• don't try to recreate a signed tag with git tag -f (see the thread extract below)

  (it is about a corner case, but quite instructive about tags in general, and it comes from another SO contributor Jakub Narebski):

Please note that the name of tag (heavyweight tag, i.e. tag object) is stored in two places:

• in the tag object itself as a contents of 'tag' header (you can see it in output of "git show <tag>" and also in output of "git cat-file -p <tag>", where <tag> is heavyweight tag, e.g. v1.6.3 in git.git repository),
• and also is default name of tag reference (reference in "refs/tags/*" namespace) pointing to a tag object.
  Note that the tag reference (appropriate reference in the "refs/tags/*" namespace) is purely local matter; what one repository has in 'refs/tags/v0.1.3', other can have in 'refs/tags/sub/v0.1.3' for example.

So when you create signed tag 'A', you have the following situation (assuming that it points at some commit)

  35805ce   <--- 5b7b4ead  <=== refs/tags/A
  (commit)       tag A
                 (tag)

Please also note that "git tag -f A A" (notice the absence of options forcing it to be an annotated tag) is a noop - it doesn't change the situation.

If you do "git tag -f -s A A": note that you force owerwriting a tag (so git assumes that you know what you are doing), and that one of -s / -a / -m options is used to force annotated tag (creation of tag object), you will get the following situation

  35805ce   <--- 5b7b4ea  <--- ada8ddc  <=== refs/tags/A
  (commit)       tag A         tag A
                 (tag)         (tag)

Note also that "git show A" would show the whole chain down to the non-tag object...

Use the "Go To Find Combo Box" with the ">of" command. CTRL+/ or CTRL+D are the standard hotkeys.

For example, go to the combo box (CTRL+/) and type: >of MyClassName. As you type, intellisense will refine the options in the dropdown.

In my experience, this is faster than Navigate To and doesn't bring up another dialog to deal with. Also, this combo box has a lot of other nifty little shortcut commands:

Using the Go To Find Combo Box

This textbox used to be the default on the Standard toolbar in Visual Studio. It was removed in Visual Studio 2012, so you have to add it back using menu Tools ? Customize. The hotkeys may have changed too: I'm not sure since mine are all customized.

I needed something similar, so I wrote https://github.com/beradrian/jsbandwidth. This is a rewrite of https://code.google.com/p/jsbandwidth/.

The idea is to make two calls through Ajax, one to download and the other to upload through POST.

It should work with both jQuery.ajax or Angular $http.

Inserting data into the middle of a text file is not a simple task. If possible, you should append it to the end of your file.

The easiest way to append data some text file is to use build-in fs.appendFile(filename, data[, options], callback) function from fs module:

var fs = require('fs')
fs.appendFile('log.txt', 'new data', function (err) {
  if (err) {
    // append failed
  } else {
    // done
  }
})

But if you want to write data to log file several times, then it'll be best to use fs.createWriteStream(path[, options]) function instead:

var fs = require('fs')
var logger = fs.createWriteStream('log.txt', {
  flags: 'a' // 'a' means appending (old data will be preserved)
})

logger.write('some data') // append string to your file
logger.write('more data') // again
logger.write('and more') // again

Node will keep appending new data to your file every time you'll call .write, until your application will be closed, or until you'll manually close the stream calling .end:

logger.end() // close string

What Ed Guiness suggested is really a performance booster , I had a query like this

select * from table where id in (id1,id2.........long list)

what i did :

DECLARE @temp table(
            ID  int
            )
insert into @temp 
select * from dbo.fnSplitter('#idlist#')

Then inner joined the temp with main table :

select * from table inner join temp on temp.id = table.id

And performance improved drastically.

<?php

    $val = $myService->getValue(); // Makes an API and database call

    echo "
        <script>
            myPlugin.start({$val});
        </script> ";

?>

If you are in a domain environment, you can also use:

winrs -r:PCNAME cmd

This will open a remote command shell.

You can use the sp_columns stored procedure:

exec sp_columns MyTable

The document.location is an object that contains properties for the current location.

The href property is one of these properties, containing the complete URL, i.e. all the other properties put together.

Some browsers allow you to assign an URL to the location object and acts as if you assigned it to the href property. Some other browsers are more picky, and requires you to use the href property. Thus, to make the code work in all browsers, you have to use the href property.

Both the window and document objects has a location object. You can set the URL using either window.location.href or document.location.href. However, logically the document.location object should be read-only (as you can't change the URL of a document; changing the URL loads a new document), so to be on the safe side you should rather use window.location.href when you want to set the URL.

I haven't had to do this, so take this with a grain of salt and a big helping of "test, test, test".

What happens if (in a safe controlled test environment) you directly modify the Host column in the mysql.user and probably mysql.db tables? (E.g., with an update statement.) I don't think MySQL uses the user's host as part of the password encoding (the PASSWORD function doesn't suggest it does), but you'll have to try it to be sure. You may need to issue a FLUSH PRIVILEGES command (or stop and restart the server).

For some storage engines (MyISAM, for instance), you may also need to check/modify the .frm file any views that user has created. The .frm file stores the definer, including the definer's host. (I have had to do this, when moving databases between hosts where there had been a misconfiguration causing the wrong host to be recorded...)

NONE of the above-given answers works for me.

My original goal was to fix the sometimes CONSTANT COMPILING of my project with VSCode.

I tried many, many ways, but NOTHING was working -- the project just WON'T COMPILIE!

Finally I found out what the problem here is:

I cloned the project from my company's repository, and all the code from there HAS TO go exactly with the versions of dependencies when the existing part of the project was coded.

In the end, I deleted the previously cloned project AGAIN (quite a few times), and cloned AGAIN (also a few times), and DID NOTHING BUT RAN "npm install", and everything started to work.

The lesson I learned here is that:

Sometimes you'll make the situation worse when you try to fix some problems (the one I had was the CONSTANT COMPILING of my project).

But it doesn't mean we cannot try to fix the problems. We can. But when everything becomes a mess, we'd better go with the original code.

Fortunately the CONSTANT COMPILING of my project happens only once a while, not all the time. It's not fixed, but I have to bear with it, otherwise my project won't even compile.

This is certainly something that has a lot of traps. I was working with Paolo Bergantino's answer, and realising that even that has some limitations. I found working with string representations of dates a good place to quickly find some of the main problems. Start with an input string like this: '12-2-2019 5:1:48.670'

and set up Paolo's function like this:

function count(re, str) {
    if (typeof re !== "string") {
        return 0;
    }
    re = (re === '.') ? ('\\' + re) : re;
    var cre = new RegExp(re, 'g');
    return ((str || '').match(cre) || []).length;
}

I wanted the regular expression to be passed in, so that the function is more reusable, secondly, I wanted the parameter to be a string, so that the client doesn't have to make the regex, but simply match on the string, like a standard string utility class method.

Now, here you can see that I'm dealing with issues with the input. With the following:

if (typeof re !== "string") {
    return 0;
}

I am ensuring that the input isn't anything like the literal 0, false, undefined, or null, none of which are strings. Since these literals are not in the input string, there should be no matches, but it should match '0', which is a string.

With the following:

re = (re === '.') ? ('\\' + re) : re;

I am dealing with the fact that the RegExp constructor will (I think, wrongly) interpret the string '.' as the all character matcher \.\

Finally, because I am using the RegExp constructor, I need to give it the global 'g' flag so that it counts all matches, not just the first one, similar to the suggestions in other posts.

I realise that this is an extremely late answer, but it might be helpful to someone stumbling along here. BTW here's the TypeScript version:

function count(re: string, str: string): number {
    if (typeof re !== 'string') {
        return 0;
    }
    re = (re === '.') ? ('\\' + re) : re;
    const cre = new RegExp(re, 'g');    
    return ((str || '').match(cre) || []).length;
}

I'd just use zip:

In [1]: from pandas import *

In [2]: def calculate(x):
   ...:     return x*2, x*3
   ...: 

In [3]: df = DataFrame({'a': [1,2,3], 'b': [2,3,4]})

In [4]: df
Out[4]: 
   a  b
0  1  2
1  2  3
2  3  4

In [5]: df["A1"], df["A2"] = zip(*df["a"].map(calculate))

In [6]: df
Out[6]: 
   a  b  A1  A2
0  1  2   2   3
1  2  3   4   6
2  3  4   6   9

We can use a not famous built-in function; divmod:

>>> s = 1234.5678
>>> i, d = divmod(s, 1)
>>> i
1234.0
>>> d
0.5678000000000338

I kind of fail to see the point, for jqGrid you can use the virtual scrolling functionality:

http://www.trirand.net/aspnetmvc/grid/performancevirtualscrolling

but then again, millions of rows with filtering can be done:

http://www.trirand.net/aspnetmvc/grid/performancelinq

I really fail to see the point of "as if there are no pages" though, I mean... there is no way to display 1,000,000 rows at once in the browser - this is 10MB of HTML raw, I kind of fail to see why users would not want to see the pages.

Anyway...

From the XAMPP panel, click on the ADMIN button on the Apache site. Then choose to edit php.ini And add the missing post_max_size to a value you are comfortable with.

Instead of downloading separate java files as suggested by Veer, you could just add this JAR file to your package.

To add the jar file to your project in Eclipse, do the following:

1. Right click on your project, click Build Path > Configure Build Path
2. Goto Libraries tab > Add External JARs
3. Locate the JAR file and add

Better Go with more simpler way by using org.json lib. Just do a very simple approach as below:

JSONObject obj = new JSONObject();
obj.put("phonetype", "N95");
obj.put("cat", "WP");

Now obj is your converted JSONObject form of your respective String. This is in case if you have name-value pairs.

For a string you can directly pass to the constructor of JSONObject. If it'll be a valid json String, then okay otherwise it'll throw an exception.

You can't select a sheet in a non-active workbook.

You must first activate the workbook, then you can select the sheet.

workbooks("A").activate
workbooks("A").worksheets("B").select 

When you use Activate it automatically activates the workbook.

Note you can select >1 sheet in a workbook:

activeworkbook.sheets(array("sheet1","sheet3")).select

but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.

1. Place a breakpoint
2. Right click on the breakpoint and select 'Edit breakpoint'
3. Insert your code. Use SHIFT+ENTER to create a new line.

It seems there is a change in how Application.COUNTA works in VB7 vs VB6. I tried the following in both versions of VB.

   ReDim allData(0 To 1, 0 To 15)
   Debug.Print Application.WorksheetFunction.CountA(allData)

In VB6 this returns 0.

Inn VB7 it returns 32

Looks like VB7 doesn't consider COUNTA to be COUNTA anymore.

Short answer is no.

XAMPP is normally built around a specific PHP version to ensure plugins and modules are all compatible and working correctly.

If your project specifically needs PHP 5.3 - the cleanest method is simply reinstalling an older version of XAMPP with PHP 5.3 packaged into it.

XAMPP 1.7.7 was their last update before moving off PHP 5.3.

Microsoft Core Library, ie they are at the heart of everything.

There is a more "massaged" explanation you may prefer:

"When Microsoft first started working on the .NET Framework, MSCorLib.dll was an acronym for Microsoft Common Object Runtime Library. Once ECMA started to standardize the CLR and parts of the FCL, MSCorLib.dll officially became the acronym for Multilanguage Standard Common Object Runtime Library."

From http://weblogs.asp.net/mreynolds/archive/2004/01/31/65551.aspx

Around 1999, to my personal memory, .Net was known as "COOL", so I am a little suspicious of this derivation. I never heard it called "COR", which is a silly-sounding name to a native English speaker.

Those two parameters (or variants of) are sent, by convention, with all events.

• sender: The object which has raised the event
• e an instance of EventArgs including, in many cases, an object which inherits from EventArgs. Contains additional information about the event, and sometimes provides ability for code handling the event to alter the event somehow.

In the case of the events you mentioned, neither parameter is particularly useful. The is only ever one page raising the events, and the EventArgs are Empty as there is no further information about the event.

Looking at the 2 parameters separately, here are some examples where they are useful.

sender

Say you have multiple buttons on a form. These buttons could contain a Tag describing what clicking them should do. You could handle all the Click events with the same handler, and depending on the sender do something different

private void HandleButtonClick(object sender, EventArgs e)
{
    Button btn = (Button)sender;
    if(btn.Tag == "Hello")
      MessageBox.Show("Hello")
    else if(btn.Tag == "Goodbye")
       Application.Exit();
    // etc.
}

Disclaimer : That's a contrived example; don't do that!

e

Some events are cancelable. They send CancelEventArgs instead of EventArgs. This object adds a simple boolean property Cancel on the event args. Code handling this event can cancel the event:

private void HandleCancellableEvent(object sender, CancelEventArgs e)
{
    if(/* some condition*/)
    {
       // Cancel this event
       e.Cancel = true;
    }
}

Most answers here are strictly related to notations and syntax of the data models at different levels of abstraction. The key difference has not been mentioned by anyone. Conceptual models surface concepts. Concepts relate to other concepts in a different way that an Entity relates to another Entity at the Logical level of abstraction. Concepts are closer to Types. Usually at Conceptual level you display Types of things (this does not mean you must use the term "type" in your naming convention) and relationships between such types. Therefore, the existence of many-to-many relationships is not the rule but rather the consequence of the relationships between type-wise elements. In Logical Models Entities represent one instance of that thing in the real world. In Conceptual models it is not expected the description of an instance of an Entity and their relationships but rather the description of the "type" or "class" of that particular Entity. Examples: - Vehicles have Wheels and Wheels are used in Vehicles. At Conceptual level this is a many-to-many relationship - A particular Vehicle (a car by instance), with one specific registration number have 5 wheels and each particular wheel, each one with a serial number is related to only that particular car. At Logical level this is a one-to-many relationship.

Conceptual covers "types/classes". Logical covers "instances".

I would add another comment about databases. I agree with one of the colleagues who commented above that Conceptual and Logical models have absolutely nothing about databases. Conceptual and Logical models describe the real world from a data perspective using notations such as ER or UML. Database vendors, smartly, designed their products to follow the same philosophy used to logically model the World and them created Relational Databases, making everyone's lifes easier. You can describe your organisation's data landscape at all the levels using Conceptual and Logical model and never use a relational database.

Well I guess this is my 2 cents...

It seems to work fine in Google Chrome. Which browser are you using? Here the proof http://jsfiddle.net/CN8XL/

Anyhow you can also access to the input value parameter through the document.FormName.checkyear.value. You have to wrap in the input in a <form> tag like with the proper name attribute, like shown below:

<form name="FormName">

If you are unfortunate enough to be stuck with an earlier version, you could do something like this,

WITH Rows AS
(
    SELECT
              ROW_NUMBER() OVER (ORDER BY [dbo].[SomeColumn]) [Row]
            , *
        FROM
              [dbo].[SomeTable]
)
SELECT TOP 10
          *
     FROM
         Rows
    WHERE Row > 10

I believe is functionaly equivalent to

SELECT * FROM SomeTable LIMIT 10 OFFSET 10 ORDER BY SomeColumn

and the best performing way I know of doing it in TSQL, before MS SQL 2012.

If there are very many rows you may get better performance using a temp table instead of a CTE.

Try this solution. It works fine.

 try{
        String url = textBox1.Text;
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        StreamReader sr = new StreamReader(response.GetResponseStream());
        HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
        doc.Load(sr);
        var aTags = doc.DocumentNode.SelectNodes("//a");
        int counter = 1;
        if (aTags != null)
        {
            foreach (var aTag in aTags)
            {
                richTextBox1.Text +=  aTag.InnerHtml +  "\n" ;
                counter++;
            }
        }
        sr.Close();
        }
        catch (Exception ex)
        {
            MessageBox.Show("Failed to retrieve related keywords." + ex);
        }

set the height to 200

Set the Font to a large variant (150+ px). As already mentioned, control the width using columns, and use a layout manager (or constraint) that will respect the preferred width & height.

Yes, you can specify the notebooks location in your profile configuration. Since it's not saving them to the directory where you started the notebook, I assume that you have this option set in your profile. You can find out the the path to the profiles directory by using:

$ ipython locate

Either in your default profile or in the profile you use, edit the ipython_notebook_config.py file and change the lines:

Note: In case you don't have a profile, or the profile folder does not contain the ipython_notebook_config.py file, use ipython profile create.

# The directory to use for notebooks.
c.NotebookManager.notebook_dir = u'/path/to/your/notebooks'

and

# The directory to use for notebooks.
c.FileNotebookManager.notebook_dir = u'/path/to/your/notebooks'

Or just comment them out if you want the notebooks saved in the current directory.

Update (April 11th 2014): in IPython 2.0 the property name in the config file changed, so it's now:

c.NotebookApp.notebook_dir = u'/path/to/your/notebooks'

Try this:

SELECT CONVERT(VARCHAR(10),GETDATE(),111)

The above statement converts your current format to YYYY/MM/DD, please refer to this link to choose your preferable format.

'1' >>> Catchall for general errors

'2' >>> Misuse of shell builtins (according to Bash documentation)

'126'>>> Command invoked cannot execute

'127'>>>"command not found"

'128'>>> Invalid argument to exit

'128+n'>>>Fatal error signal "n"

'130'>>> Script terminated by Control-C

'255'>>>Exit status out of range

This is for bash. However, for other applications, there are different exit codes.

Strings in Python are immutable (meaning that their data cannot be modified) so the replace method doesn't modify the string - it returns a new string. You could fix your code as follows:

for i in hello:
    j = i.replace(' ','')
    k.append(j)

However a better way to achieve your aim is to use a list comprehension. For example the following code removes leading and trailing spaces from every string in the list using strip:

hello = [x.strip(' ') for x in hello]

To complement the other answers: if you want to reset all background properties to their initial value (which includes background-color: transparent and background-image: none) without explicitly specifying any value such as transparent or none, you can do so by writing:

background: initial;

Yes you can achive this by ajax post method. on server side you can use httphandler. So we are not using any server controls as per your requirement.

with ajax you can show the upload progress also.

you will have to read the file as a inputstream.

using (FileStream fs = File.Create("D:\\_Workarea\\" + fileName))
    {
        Byte[] buffer = new Byte[32 * 1024];
        int read = context.Request.GetBufferlessInputStream().Read(buffer, 0, buffer.Length);
        while (read > 0)
        {
            fs.Write(buffer, 0, read);
            read = context.Request.GetBufferlessInputStream().Read(buffer, 0, buffer.Length);
        }
    } 

Sample Code

function sendFile(file) {              
        debugger;
        $.ajax({
            url: 'handler/FileUploader.ashx?FileName=' + file.name, //server script to process data
            type: 'POST',
            xhr: function () {
                myXhr = $.ajaxSettings.xhr();
                if (myXhr.upload) {
                    myXhr.upload.addEventListener('progress', progressHandlingFunction, false);
                }
                return myXhr;
            },
            success: function (result) {                    
                //On success if you want to perform some tasks.
            },
            data: file,
            cache: false,
            contentType: false,
            processData: false
        });
        function progressHandlingFunction(e) {
            if (e.lengthComputable) {
                var s = parseInt((e.loaded / e.total) * 100);
                $("#progress" + currFile).text(s + "%");
                $("#progbarWidth" + currFile).width(s + "%");
                if (s == 100) {
                    triggerNextFileUpload();
                }
            }
        }
    }

As karim79 mentioned, the first is the most concise. However I could argue that the second is more understandable as it is not obvious/known to some Javascript/jQuery programmers that non-zero/false values are evaluated to true in if-statements. And because of that, the third method is incorrect.

With the help of user=User.query.filter_by(username=form.username.data).first() statement you will get the specified user in user variable.

Now you can change the value of the new object variable like user.no_of_logins += 1 and save the changes with the session's commit method.

If you are switching on the value of a single variable then I'd use a switch every time, it's what the construct was made for.

Otherwise, stick with multiple if-else statements.

For jquery users, how about $.trim(s)

To do this, I had to come up with an intermediate data structure:

class KeyDataPoint {
    String key;
    DateTime timestamp;
    Number data;
    // obvious constructor and getters
}

With this in place, the approach is to "flatten" each MultiDataPoint into a list of (timestamp, key, data) triples and stream together all such triples from the list of MultiDataPoint.

Then, we apply a groupingBy operation on the string key in order to gather the data for each key together. Note that a simple groupingBy would result in a map from each string key to a list of the corresponding KeyDataPoint triples. We don't want the triples; we want DataPoint instances, which are (timestamp, data) pairs. To do this we apply a "downstream" collector of the groupingBy which is a mapping operation that constructs a new DataPoint by getting the right values from the KeyDataPoint triple. The downstream collector of the mapping operation is simply toList which collects the DataPoint objects of the same group into a list.

Now we have a Map<String, List<DataPoint>> and we want to convert it to a collection of DataSet objects. We simply stream out the map entries and construct DataSet objects, collect them into a list, and return it.

The code ends up looking like this:

Collection<DataSet> convertMultiDataPointToDataSet(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.getData().entrySet().stream()
                           .map(e -> new KeyDataPoint(e.getKey(), mdp.getTimestamp(), e.getValue())))
        .collect(groupingBy(KeyDataPoint::getKey,
                    mapping(kdp -> new DataPoint(kdp.getTimestamp(), kdp.getData()), toList())))
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

I took some liberties with constructors and getters, but I think they should be obvious.

You can also replace complicated condition with single method call to make it less evil in maintain.

If you're live watching if unloading class worked in JConsole or something, try also adding java.lang.System.gc() at the end of your class unloading logic. It explicitly triggers Garbage Collector.

That's a half-open interval.

• A closed interval [a,b] includes the end points.
• An open interval (a,b) excludes them.

In your case the end-point at the start of the interval is included, but the end is excluded. So it means the interval "first1 <= x < last1".

Half-open intervals are useful in programming because they correspond to the common idiom for looping:

for (int i = 0; i < n; ++i) { ... } 

Here i is in the range [0, n).

The internals of the GUI system call that method, and they pass in the Graphics parameter as a graphics context onto which you can draw.

deleting the local maven repository helped me

This is just a version mismatch. You have compiled your code using java version 9 and your current JRE is version 8. Try upgrading your JRE to 9.

49 = Java 5
50 = Java 6
51 = Java 7
52 = Java 8
53 = Java 9
54 = Java 10
55 = Java 11
56 = Java 12
57 = Java 13
58 = Java 14

Just change the directory to another one and come back. Probably that one has been deleted or moved.

In C++, 5/9 computes the result as an integer as both the operands are integers. You need to give an hint to the compiler that you want the result as a float/double. You can do it by explictly casting one of the operands like ((double)5)/9;

EDIT Since it is tagged C++, you can do the casting bit more elegantly using the static_cast. For example: static_cast<double>(5)/9. Although in this particular case you can directly use 5.0/9 to get the desired result, the casting will be helpful when you have variables instead of constant values such as 5.

I create HashMaps in bash 3 using dynamic variables. I explained how that works in my answer to: Associative arrays in Shell scripts

Also you can take a look in shell_map, which is a HashMap implementation made in bash 3.

You can try something like this.

<html>
<head>
    <title>test</title>
    <script>
        function openChecking(){
            // alert("open");
            var width = Number(screen.width-(screen.width*0.25));  
            var height = Number(screen.height-(screen.height*0.25));
            var leftscr = Number((screen.width/2)-(width/2)); // center the window
            var topscr = Number((screen.height/2)-(height/2));
            var url = "";
            var title = 'popup';
            var properties = 'width='+width+', height='+height+', top='+topscr+', left='+leftscr;
            var popup = window.open(url, title, properties);
            var crono = window.setInterval(function() {
                if (popup.closed !== false) { // !== opera compatibility reasons
                    window.clearInterval(crono);
                    checkClosed();
                }
            }, 250); //we check if the window is closed every 1/4 second
        }   
        function checkClosed(){
            alert("closed!!");
            // do something
        }
    </script>    
</head>
<body>
    <button onclick="openChecking()">Click Me</button>
</body>
</html>

When the user closes the window, the callback will be fired.

You could do this:

SELECT * FROM table WHERE cast(YOUR_INTEGER_VALUE as varchar) = 'string of numbers'

Taken from this comment on the PHP manual, you could use this:

function gen_uuid() {
    return sprintf( '%04x%04x-%04x-%04x-%04x-%04x%04x%04x',
        // 32 bits for "time_low"
        mt_rand( 0, 0xffff ), mt_rand( 0, 0xffff ),

        // 16 bits for "time_mid"
        mt_rand( 0, 0xffff ),

        // 16 bits for "time_hi_and_version",
        // four most significant bits holds version number 4
        mt_rand( 0, 0x0fff ) | 0x4000,

        // 16 bits, 8 bits for "clk_seq_hi_res",
        // 8 bits for "clk_seq_low",
        // two most significant bits holds zero and one for variant DCE1.1
        mt_rand( 0, 0x3fff ) | 0x8000,

        // 48 bits for "node"
        mt_rand( 0, 0xffff ), mt_rand( 0, 0xffff ), mt_rand( 0, 0xffff )
    );
}

1. Use below JPQL query.

select i from Instructor i where i.address LIKE CONCAT('%',:address ,'%')");

2. Use below Criteria code for the same:

@Test
public void findAllHavingAddressLike() {
    CriteriaBuilder cb = criteriaUtils.criteriaBuilder();
    CriteriaQuery<Instructor> cq = cb.createQuery(Instructor.class);
    Root<Instructor> root = cq.from(Instructor.class);
    printResultList(cq.select(root).where(
        cb.like(root.get(Instructor_.address), "%#1074%")));
}

Here is example for list of Objects

Map<String, Long> requirementCountMap = requirements.stream().collect(Collectors.groupingBy(Requirement::getRequirementType, Collectors.counting()));

This walks all sub-directories; summing file sizes:

import os

def get_size(start_path = '.'):
    total_size = 0
    for dirpath, dirnames, filenames in os.walk(start_path):
        for f in filenames:
            fp = os.path.join(dirpath, f)
            # skip if it is symbolic link
            if not os.path.islink(fp):
                total_size += os.path.getsize(fp)

    return total_size

print(get_size(), 'bytes')

And a oneliner for fun using os.listdir (Does not include sub-directories):

import os
sum(os.path.getsize(f) for f in os.listdir('.') if os.path.isfile(f))

Reference:

• os.path.getsize - Gives the size in bytes
• os.walk
• os.path.islink

Updated To use os.path.getsize, this is clearer than using the os.stat().st_size method.

Thanks to ghostdog74 for pointing this out!

os.stat - st_size Gives the size in bytes. Can also be used to get file size and other file related information.

import os

nbytes = sum(d.stat().st_size for d in os.scandir('.') if d.is_file())

Update 2018

If you use Python 3.4 or previous then you may consider using the more efficient walk method provided by the third-party scandir package. In Python 3.5 and later, this package has been incorporated into the standard library and os.walk has received the corresponding increase in performance.

Update 2019

Recently I've been using pathlib more and more, here's a pathlib solution:

from pathlib import Path

root_directory = Path('.')
sum(f.stat().st_size for f in root_directory.glob('**/*') if f.is_file())

Map [Enter] key to work like the [Tab] key

I've rewritten Andre Van Zuydam's answer, which didn't work for me, in jQuery. This caputures both Enter and Shift+Enter. Enter tabs forward, and Shift+Enter tabs back.

I've also rewritten the way self is initialized by the current item in focus. The form is also selected that way. Here's the code:

// Map [Enter] key to work like the [Tab] key
// Daniel P. Clark 2014

// Catch the keydown for the entire document
$(document).keydown(function(e) {

  // Set self as the current item in focus
  var self = $(':focus'),
      // Set the form by the current item in focus
      form = self.parents('form:eq(0)'),
      focusable;

  // Array of Indexable/Tab-able items
  focusable = form.find('input,a,select,button,textarea,div[contenteditable=true]').filter(':visible');

  function enterKey(){
    if (e.which === 13 && !self.is('textarea,div[contenteditable=true]')) { // [Enter] key

      // If not a regular hyperlink/button/textarea
      if ($.inArray(self, focusable) && (!self.is('a,button'))){
        // Then prevent the default [Enter] key behaviour from submitting the form
        e.preventDefault();
      } // Otherwise follow the link/button as by design, or put new line in textarea

      // Focus on the next item (either previous or next depending on shift)
      focusable.eq(focusable.index(self) + (e.shiftKey ? -1 : 1)).focus();

      return false;
    }
  }
  // We need to capture the [Shift] key and check the [Enter] key either way.
  if (e.shiftKey) { enterKey() } else { enterKey() }
});

The reason textarea

is included is because we "do" want to tab into it. Also, once in, we don't want to stop the default behavior of Enter from putting in a new line.

The reason a and button

allow the default action, "and" still focus on the next item, is because they don't always load another page. There can be a trigger/effect on those such as an accordion or tabbed content. So once you trigger the default behavior, and the page does its special effect, you still want to go to the next item since your trigger may have well introduced it.

Have look at dom4j or jdom. Both libraries allow creating a Document and allow printing the document as xml. Both are widly used, pretty easy to use and you'll find a lot of examples and snippets.

dom4j - Quick start guide

cp -r `ls -A | grep -v "c"` $HOME/

Core jQuery doesn't have anything special for touch events, but you can easily build your own using the following events

• touchstart
• touchmove
• touchend
• touchcancel

For example, the touchmove

document.addEventListener('touchmove', function(e) {
    e.preventDefault();
    var touch = e.touches[0];
    alert(touch.pageX + " - " + touch.pageY);
}, false);

This works in most WebKit based browsers (incl. Android).

Here is some good documentation.

It will depend on your purpose. If interoperability with other systems is important then it seems rawurlencode is the way to go. The one exception is legacy systems which expect the query string to follow form-encoding style of spaces encoded as + instead of %20 (in which case you need urlencode).

rawurlencode follows RFC 1738 prior to PHP 5.3.0 and RFC 3986 afterwards (see http://us2.php.net/manual/en/function.rawurlencode.php)

Returns a string in which all non-alphanumeric characters except -_.~ have been replaced with a percent (%) sign followed by two hex digits. This is the encoding described in » RFC 3986 for protecting literal characters from being interpreted as special URL delimiters, and for protecting URLs from being mangled by transmission media with character conversions (like some email systems).

Note on RFC 3986 vs 1738. rawurlencode prior to php 5.3 encoded the tilde character (~) according to RFC 1738. As of PHP 5.3, however, rawurlencode follows RFC 3986 which does not require encoding tilde characters.

urlencode encodes spaces as plus signs (not as %20 as done in rawurlencode)(see http://us2.php.net/manual/en/function.urlencode.php)

Returns a string in which all non-alphanumeric characters except -_. have been replaced with a percent (%) sign followed by two hex digits and spaces encoded as plus (+) signs. It is encoded the same way that the posted data from a WWW form is encoded, that is the same way as in application/x-www-form-urlencoded media type. This differs from the » RFC 3986 encoding (see rawurlencode()) in that for historical reasons, spaces are encoded as plus (+) signs.

This corresponds to the definition for application/x-www-form-urlencoded in RFC 1866.

Also, RFC 2396 is worth a look. RFC 2396 defines valid URI syntax. The main part we're interested in is from 3.4 Query Component:

Within a query component, the characters ";", "/", "?", ":", "@",
"&", "=", "+", ",", and "$" are reserved.

As you can see, the + is a reserved character in the query string and thus would need to be encoded as per RFC 3986 (as in rawurlencode).

Use $.ajax to call a server context (or URL, or whatever) to invoke a particular 'action'. What you want is something like:

$.ajax({ url: '/my/site',
         data: {action: 'test'},
         type: 'post',
         success: function(output) {
                      alert(output);
                  }
});

On the server side, the action POST parameter should be read and the corresponding value should point to the method to invoke, e.g.:

if(isset($_POST['action']) && !empty($_POST['action'])) {
    $action = $_POST['action'];
    switch($action) {
        case 'test' : test();break;
        case 'blah' : blah();break;
        // ...etc...
    }
}

I believe that's a simple incarnation of the Command pattern.

I prefer doing a "PAD" to the data. MySql calls it LPAD, but you can work your way around to doing the same thing in SQL Server.

ORDER BY  REPLACE(STR(ColName, 3), SPACE(1), '0') 

This formula will provide leading zeroes based on the Column's length of 3. This functionality is very useful in other situations outside of ORDER BY, so that is why I wanted to provide this option.

Results: 1 becomes 001, and 10 becomes 010, while 100 remains the same.

Why don't you introduce a service layer. then your controller will be lean and more readable, then your all controller functions will be pure actions. you can decompose business logic as you much as you need within service layer . code reusability is hight . no impact on models and repositories.

You can now use RPC libraries that support Python and Javascript such as zerorpc

From their front page:

Node.js Client

var zerorpc = require("zerorpc");

var client = new zerorpc.Client();
client.connect("tcp://127.0.0.1:4242");

client.invoke("hello", "RPC", function(error, res, more) {
    console.log(res);
});

Python Server

import zerorpc

class HelloRPC(object):
    def hello(self, name):
        return "Hello, %s" % name

s = zerorpc.Server(HelloRPC())
s.bind("tcp://0.0.0.0:4242")
s.run()

inside shell:

mongod --version

So in Short,

vi ~/.proxy_info

export http_proxy=<username>:<password>@<proxy>:8080
export https_proxy=<username>:<password>@<proxy>:8080

source ~/.proxy_info

Hope this helps someone in hurry :)

I would always recommend going to the authoritative source when trying to understand the meaning and purpose of HTTP headers.

The "Host" header field in a request provides the host and port
information from the target URI, enabling the origin server to
distinguish among resources while servicing requests for multiple
host names on a single IP address.

If You have 404 or errors while sudo apt-get install php-curl just try

sudo apt-get update

and again try

sudo apt-get install php-curl

But notice what version was installed (i use php7.3 and php7.4-curl was installed - so it will not work)

try then

sudo apt-get install php7.3-curl

At the end You may want to restart services like: apache2 or php-fpm:

sudo apache2 restart
sudo service php7.3-fpm restart

this worked for me.

Check if curl is on the installed modules list for current php:

php -m

I found that it was better to add to the table row by row if your table has a primary key. Inserting the entire table at once creates a conflict on the auto increment.

Here's my stored Proc

CREATE PROCEDURE dbo.usp_InsertRowsIntoTable
@Year       int,
@TeamName   nvarchar(50),
AS
INSERT INTO [dbo.TeamOverview]
(Year,TeamName)
VALUES (@Year, @TeamName);
RETURN

I put this code in a loop for every row that I need to add to my table:

insertRowbyRowIntoTable(Convert.ToInt16(ddlChooseYear.SelectedValue), name);

And here is my Data Access Layer code:

        public void insertRowbyRowIntoTable(int ddlValue, string name)
    { 
        SqlConnection cnTemp = null;
        string spName = null;
        SqlCommand sqlCmdInsert = null;

        try
        {
            cnTemp = helper.GetConnection();
            using (SqlConnection connection = cnTemp)
            {
                if (cnTemp.State != ConnectionState.Open)
                    cnTemp.Open();
                using (sqlCmdInsert = new SqlCommand(spName, cnTemp))
                {
                    spName = "dbo.usp_InsertRowsIntoOverview";
                    sqlCmdInsert = new SqlCommand(spName, cnTemp);
                    sqlCmdInsert.CommandType = CommandType.StoredProcedure;

                    sqlCmdInsert.Parameters.AddWithValue("@Year", ddlValue);
                    sqlCmdInsert.Parameters.AddWithValue("@TeamName", name);

                    sqlCmdInsert.ExecuteNonQuery();

                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
        finally
        {
            if (sqlCmdInsert != null)
                sqlCmdInsert.Dispose();

            if (cnTemp.State == ConnectionState.Open)
                cnTemp.Close();
        }

    }

You can make <button> tag to do action like this:

<a href="http://www.google.com/">
   <button>Visit Google</button>
</a>

or:

<a href="http://www.google.com/">
   <input type="button" value="Visit Google" />
</a>

It's simple and no javascript required!

NOTE:

This approach is not valid from HTML structure. But, it works on many modern browser. See following reference :

• For <button>; and
• For <input type="button />

The easiest way is to set your repository to the branch you want to merge with, and then run

git checkout [branch with file] [path to file you would like to merge]

If you run

git status

you will see the file already staged...

Then run

git commit -m "Merge changes on '[branch]' to [file]"

Simple.

Here is an example

private void doOpenFile() {
    int result = myFileChooser.showOpenDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        Path path = myFileChooser.getSelectedFile().toPath();

        try {
            String contentString = "";

            for (String s : Files.readAllLines(path, StandardCharsets.UTF_8)) {
                contentString += s;
            }

            jText.setText(contentString);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

private void doSaveFile() {
    int result = myFileChooser.showSaveDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        // We'll be making a mytmp.txt file, write in there, then move it to
        // the selected
        // file. This takes care of clearing that file, should there be
        // content in it.
        File targetFile = myFileChooser.getSelectedFile();

        try {
            if (!targetFile.exists()) {
                targetFile.createNewFile();
            }

            FileWriter fw = new FileWriter(targetFile);

            fw.write(jText.getText());
            fw.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

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

Should look something like this, added to your code:

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

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

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

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

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

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

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

For decoding a series of bytes to a normal string message I finally got it working with UTF-8 encoding with this code:

/* Convert a list of UTF-8 numbers to a normal String
 * Usefull for decoding a jms message that is delivered as a sequence of bytes instead of plain text
 */
public String convertUtf8NumbersToString(String[] numbers){
    int length = numbers.length;
    byte[] data = new byte[length];

    for(int i = 0; i< length; i++){
        data[i] = Byte.parseByte(numbers[i]);
    }
    return new String(data, Charset.forName("UTF-8"));
}

I think that none of the above answers give the real example to you the difference between a nested class and a static nested class in term of application design. And the main difference between static nested class and inner class is the ability to access the outer class instance field.

Let us take a look at the two following examples.

Static nest class: An good example of using static nested classes is builder pattern (https://dzone.com/articles/design-patterns-the-builder-pattern).

For BankAccount we use a static nested class, mainly because

1. Static nest class instance could be created before the outer class.

2. In the builder pattern, the builder is a helper class which is used to create the BankAccount.

3. BankAccount.Builder is only associated with BankAccount. No other classes are related to BankAccount.Builder. so it is better to organize them together without using name convention.

public class BankAccount {

    private long accountNumber;
    private String owner;
    ...

    public static class Builder {

    private long accountNumber;
    private String owner;
    ...

    static public Builder(long accountNumber) {
        this.accountNumber = accountNumber;
    }

    public Builder withOwner(String owner){
        this.owner = owner;
        return this; 
    }

    ...
    public BankAccount build(){
            BankAccount account = new BankAccount(); 
            account.accountNumber = this.accountNumber;
            account.owner = this.owner;
            ...
            return account;
        }
    }
}

Inner class: A common use of inner classes is to define an event handler. https://docs.oracle.com/javase/tutorial/uiswing/events/generalrules.html

For MyClass, we use the inner class, mainly because:

1. Inner class MyAdapter need to access the outer class member.

2. In the example, MyAdapter is only associated with MyClass. No other classes are related to MyAdapter. so it is better to organize them together without using a name convention

public class MyClass extends Applet {
    ...
        someObject.addMouseListener(new MyAdapter());
    ...
    class MyAdapter extends MouseAdapter {
        public void mouseClicked(MouseEvent e) {
            ...// Event listener implementation goes here...
            ...// change some outer class instance property depend on the event
        }
    }
}

From the documentation:

contentType (default: 'application/x-www-form-urlencoded; charset=UTF-8')

Type: String

When sending data to the server, use this content type. Default is "application/x-www-form-urlencoded; charset=UTF-8", which is fine for most cases. If you explicitly pass in a content-type to $.ajax(), then it'll always be sent to the server (even if no data is sent). If no charset is specified, data will be transmitted to the server using the server's default charset; you must decode this appropriately on the server side.

and:

dataType (default: Intelligent Guess (xml, json, script, or html))

Type: String

The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response (an XML MIME type will yield XML, in 1.4 JSON will yield a JavaScript object, in 1.4 script will execute the script, and anything else will be returned as a string).

They're essentially the opposite of what you thought they were.

Another way would be to open terminal ctrl+` execute node. Now you have a node REPL active. You can now send your file or selected text to terminal. In order to do that open VSCode command pallete (F1 or ctrl+shift+p) and execute >run selected text in active terminal or >run active file in active terminal.

If you need a clean REPL before executing your code you will have to restart the node REPL. This is done when in the Terminal with the node REPL ctrl+c ctrl+c to exit it and typing node to start new.

You could probably key bind the command pallete commands to whatever key you wish.

PS: node should be installed and in your path

So to put it all together by using malloc():

int main(int argc, char** argv) {
    typedef struct{
        char* firstName;
        char* lastName;
        int day;
        int month;
        int year;

    }STUDENT;

    int numStudents=3;
    int x;
    STUDENT* students = malloc(numStudents * sizeof *students);
    for (x = 0; x < numStudents; x++){
        students[x].firstName=(char*)malloc(sizeof(char*));
        scanf("%s",students[x].firstName);
        students[x].lastName=(char*)malloc(sizeof(char*));
        scanf("%s",students[x].lastName);
        scanf("%d",&students[x].day);
        scanf("%d",&students[x].month);
        scanf("%d",&students[x].year);
    }

    for (x = 0; x < numStudents; x++)
        printf("first name: %s, surname: %s, day: %d, month: %d, year: %d\n",students[x].firstName,students[x].lastName,students[x].day,students[x].month,students[x].year);

    return (EXIT_SUCCESS);
}

If you are using Ubuntu Linux:

1. Install zip

   sudo apt-get install zip
   

2. Zip your folder:

   zip -r {filename.zip} {foldername}
   

If you are using Microsoft Windows:

Windows does not come with a command-line zip program, despite Windows Explorer natively supporting Zip files since the Plus! pack for Windows 98.

I recommend the open-source 7-Zip utility which includes a command-line executable and supports many different archive file types, especially its own *.7z format which offers superior compression ratios to traditional (PKZIP) *.zip files:

1. Download 7-Zip from the 7-Zip home page

2. Add the path to 7z.exe to your PATH environment variable. See this QA: How to set the path and environment variables in Windows

3. Open a new command-prompt window and use this command to create a PKZIP *.zip file:

   7z a -tzip {yourfile.zip} {yourfolder}
   

Cross-platform Java:

If you have the Java JDK installed then you can use the jar utility to create Zip files, as *.jar files are essentially just renamed *.zip (PKZIP) files:

jar -cfM {yourfile.zip} {yourfolder}

Explanation: * -c compress * -f specify filename * -M do not include a MANIFEST file

This is the simple way:

text = "the little red hen"
count = text.Split("e").Length -1 ' Equals 4
count = text.Split("t").Length -1 ' Equals 3

Here's a brief one for getting a specified number of tweets from your timeline. It basically does the same thing as the other examples, only with less code.

Just fill in the keys and adjust $count to your liking:

$url = 'https://api.twitter.com/1.1/statuses/user_timeline.json';
$count = '10';

$oauth = array('count' => $count,
               'oauth_consumer_key' => '[CONSUMER KEY]',
               'oauth_nonce' => md5(mt_rand()),
               'oauth_signature_method' => 'HMAC-SHA1',
               'oauth_timestamp' => time(),
               'oauth_token' => '[ACCESS TOKEN]',
               'oauth_version' => '1.0');

$oauth['oauth_signature'] = base64_encode(hash_hmac('sha1', 'GET&' . rawurlencode($url) . '&' . rawurlencode(implode('&', array_map(function ($v, $k) { return $k . '=' . $v; }, $oauth, array_keys($oauth)))), '[CONSUMER SECRET]&[ACCESS TOKEN SECRET]', true));

$twitterData = json_decode(file_get_contents($url . '?count=' . $count, false, stream_context_create(array('http' => array('method' => 'GET',
                                                                                                                           'header' => 'Authorization: OAuth ' 
                                                                                                                                       . implode(', ', array_map(function ($v, $k) { return $k . '="' . rawurlencode($v) . '"'; }, $oauth, array_keys($oauth))))))));

This one uses anonymous functions and file_get_contents instead of the cURL library. Note the use of an MD5 hashed nonce. Everyone seems to be going along with the time() nonce, however, most examples on the web concerning OAuth use some kind of encrypted string (like this one: http://www.sitepoint.com/understanding-oauth-1/). This makes more sense to me too.

Further note: you need PHP 5.3+ for the anonymous functions (in case your server/computer is in some cold war cave and you can't upgrade it).

The solution is DO NOT USE SPACES!

<urlMappings enabled="true">
<add mappedUrl="~/loginout.aspx" url="~/Account/Login"/>
</urlMappings>

That worked but it's ugly. Eventually we traced it down to a web.config entry added by Visual Studio some time earlier:

<add key="webpages:Enabled" value="true" />

As we'd been unable to work out precisely what that does, we took it out, which solved the problem for us immediately.

Yes, you can select the data, calculate the difference, and insert all values in the other table:

insert into #temp2 (Difference)
select previous - Present
from #TEMP1

The Substring method provides us a way to extract a particular string from the original string based on a starting position and length. If only one argument is provided, it is taken to be the starting position, and the remainder of the string is outputted.

PS > "test_string".Substring(0,4)
Test
PS > "test_string".Substring(4)
_stringPS >

link text

But this is easier...

 $s = 'Hello World is in here Hello World!'
 $p = 'Hello World'
 $s -match $p

And finally, to recurse through a directory selecting only the .txt files and searching for occurrence of "Hello World":

dir -rec -filter *.txt | Select-String 'Hello World'

You should create separate component, which will be listening to state changes and updating on every state change:

import store from '../reducers/store';

class Items extends Component {
  constructor(props) {
    super(props);

    this.state = {
      items: [],
    };

    store.subscribe(() => {
      // When state will be updated(in our case, when items will be fetched), 
      // we will update local component state and force component to rerender 
      // with new data.

      this.setState({
        items: store.getState().items;
      });
    });
  }

  render() {
    return (
      <div>
        {this.state.items.map((item) => <p> {item.title} </p> )}
      </div>
    );
  }
};

render(<Items />, document.getElementById('app'));

It is very simple to update using join query in SQL .You can do it without using FROM clause. Here is an example :

    UPDATE customer_table c 

      JOIN  
          employee_table e
          ON c.city_id = e.city_id  
      JOIN 
          anyother_ table a
          ON a.someID = e.someID

    SET c.active = "Yes"

    WHERE c.city = "New york";

You can use the following code:

dateForButton = dateForButton.Subtract(TimeSpan.FromDays(1));

With Java8, non heap region no more contains PermGen but Metaspace, which is a major change in Java8, supposed to get rid of out of memory errors with java as metaspace size can be increased depending on the space required by jvm for class data.

Easiest Solution I found:

You can force json_encode to use actual numbers for values that look like numbers:

json_encode($data, JSON_NUMERIC_CHECK) 

(since PHP 5.3.3).

Or you could just cast your ID to an int.

$row = $result->fetch_assoc();
$id = (int) $row['userid'];

I actually don‘t see your issue. Globally is any package which is in your python3 path‘s site package folder.

If you want to use it just locally then you must configure a virtualenv and reinstall the packages with an activated virtual environment.

Despite its very explicit and forceful description, RETURN did not work for me inside a stored procedure (to skip further execution). I had to modify the condition logic. Happens on both SQL 2008, 2008 R2:

create proc dbo.prSess_Ins
(
    @sSessID    varchar( 32 )
,   @idSess     int out
)
as
begin
    set nocount on

    select  @id=    idSess
        from    tbSess
        where   sSessID = @sSessID

    if  @idSess > 0 return  -- exit sproc here

    begin   tran
        insert  tbSess  ( sSessID ) values  ( @sSessID )
        select  @idSess=    scope_identity( )
    commit
end

had to be changed into:

    if  @idSess is null
    begin
        begin   tran
            insert  tbSess  ( sSessID ) values  ( @sSessID )
            select  @idSess=    scope_identity( )
        commit
    end

Discovered as a result of finding duplicated rows. Debugging PRINTs confirmed that @idSess had value greater than zero in the IF check - RETURN did not break execution!

The solution is given in the error itself, Goto My computer(Right click)-->properties-->Advanced system settings-->Environment variables-->Create new variable.

Give the following details to it:

Variable name : JAVA_HOME.

Variable value : (your path to java jdk installation folder).

To find the path for java installation, go to program files in your window installation drive (normally C drive). Find folder named JAVA, in that navigate to JDK folder.

Copy the link address from the top, and paste it in the Variable value .

Now Press Ok and once environment variable gets created restart the android studio.

Hope it helps.

You can try this way -

ObjectAnimator.ofFloat(view, "translationX", 100f).apply {
    duration = 2000
    start()
}

Note - view is your view where you want animation.

If you need to convert the instance of System.Xml.Linq.XDocument into the instance of the System.Xml.XmlDocument this extension method will help you to do not lose the XML declaration in the resulting XmlDocument instance:

using System.Xml; 
using System.Xml.Linq;

namespace www.dimaka.com
{ 
    internal static class LinqHelper 
    { 
        public static XmlDocument ToXmlDocument(this XDocument xDocument) 
        { 
            var xmlDocument = new XmlDocument(); 
            using (var reader = xDocument.CreateReader()) 
            { 
                xmlDocument.Load(reader); 
            }

            var xDeclaration = xDocument.Declaration; 
            if (xDeclaration != null) 
            { 
                var xmlDeclaration = xmlDocument.CreateXmlDeclaration( 
                    xDeclaration.Version, 
                    xDeclaration.Encoding, 
                    xDeclaration.Standalone);

                xmlDocument.InsertBefore(xmlDeclaration, xmlDocument.FirstChild); 
            }

            return xmlDocument; 
        } 
    } 
}

Hope that helps!

CellSpacing as the name suggests it is the Space between the Adjacent cells and CellPadding on the other hand means the padding around the cell content.

You need a reference to the class that contains the method you want to call. Let's say we have two classes, A and B. B has a method you want to call from A. Class A would look like this:

public class A
{
    B b; // A reference to B

    b = new B(); // Creating object of class B

    b.doSomething();  // Calling a method contained in class B from class A
}

B, which contains the doSomething() method would look like this:

public class B
{
    public void doSomething()
    {
        System.out.println("Look, I'm doing something in class B!");
    }
}

All you need to do is to add filter method in RecyclerView.Adapter:

public void filter(String text) {
    items.clear();
    if(text.isEmpty()){
        items.addAll(itemsCopy);
    } else{
        text = text.toLowerCase();
        for(PhoneBookItem item: itemsCopy){
            if(item.name.toLowerCase().contains(text) || item.phone.toLowerCase().contains(text)){
                items.add(item);
            }
        }
    }
    notifyDataSetChanged();
}

itemsCopy is initialized in adapter's constructor like itemsCopy.addAll(items).

If you do so, just call filter from OnQueryTextListener:

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
    @Override
    public boolean onQueryTextSubmit(String query) {
        adapter.filter(query);
        return true;
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        adapter.filter(newText);
        return true;
    }
});

It's an example from filtering my phonebook by name and phone number.

I recently had this issue and all above solutions didn't work for me.

The reason why it works on your simulator but not real devices is probably related to your Development Certificate.

So I revoked my certificate on Apple Developer Portal and request a new one on my computer. Here are the steps:

1. Goto Apple Developer Portal and revoke your old (not working) development certificate.
2. Add iOS App Development Certificate
3. Follow the step on from Apple
4. Download the newly generated certificate and add it (double click) to your Keychain
5. Make sure it is in your XCode Accounts

Then it works!

Hope it helps!

In an Excel pivot table, you are correct that a filter only allows values that are explicitly selected. If the filter field is placed on the pivot table rows or columns, however, you get a much wider set of Label Filter conditions, including Greater Than. If you did that in your case, then the added benefit would be that the various probability levels that match your condition are shown in the body of the table.

We declare a variable 'a'

SET **@a** = (SELECT MAX( customer_id ) FROM customers) +1;

INSERT INTO customers
  ( customer_id, firstname, surname )
VALUES 
  (**@a**, 'jim', 'sock')

I really love this excerpt from 10 Things I hate about git (it gives a short explanation for rebase in its second example):

3. Crappy documentation

The man pages are one almighty “f*** you”¹. They describe the commands from the perspective of a computer scientist, not a user. Case in point:

git-push – Update remote refs along with associated objects

Here’s a description for humans:

git-push – Upload changes from your local repository into a remote repository

Update, another example: (thanks cgd)

git-rebase – Forward-port local commits to the updated upstream head

Translation:

git-rebase – Sequentially regenerate a series of commits so they can be 
             applied directly to the head node

And then we have

git-merge - Join two or more development histories together

which is a good description.

Remember that collections in C# are zero-based (in other words, the first item in a collection is at position zero). If you have two items in your list, and you want to select the last item, use SelectedIndex = 1.

Despite the existence of =begin and =end, the normal and a more correct way to comment is to use #'s on each line. If you read the source of any ruby library, you will see that this is the way multi-line comments are done in almost all cases.

tr td 
{
    border-bottom: 2px solid silver;
}

or if you want the border inside the TR tag, you can do this:

tr td {
    box-shadow: inset 0px -2px 0px silver;
}

As a quick solution you can copy the JavaFX runtime JAR file and those referenced from Oracle JRE(JDK) or any self-contained application that uses JavaFX(e.g. JavaFX Scene Builder 2.0):

cp <JRE_WITH_JAVAFX_HOME>/lib/ext/jfxrt.jar     <JRE_HOME>/lib/ext/
cp <JRE_WITH_JAVAFX_HOME>/lib/javafx.properties <JRE_HOME>/lib/
cp <JRE_WITH_JAVAFX_HOME>/lib/amd64/libprism_*  <JRE_HOME>/lib/amd64/
cp <JRE_WITH_JAVAFX_HOME>/lib/amd64/libglass.so <JRE_HOME>/lib/amd64/
cp <JRE_WITH_JAVAFX_HOME>/lib/amd64/libjavafx_* <JRE_HOME>/lib/amd64/

just make sure you have the gtk 2.18 or higher

Am afraid this question has been answered a few times, Pls take a look at the following if it's related

• Flexbox and Internet Explorer 11 (display:flex in <html>?)
• Flexbox not working in Internet Explorer 11

If you're deploying a local website just for yourself or certain clients, you can get around this by running mklink /D MyImages "C:/MyImages" in the website root directory as an admin in cmd. Then in the html, do <img src="MyImages/whatever.jpg"> and the symbolic link established by mklink will connect the relative src link with the link on your C drive. It solved this issue for me, so it may help others who come to this question.

(Obviously this won't work for public websites since you can't run cmd commands on people's computers easily)

Copy the ROOT (Default) Web App into Eclipse.

Eclipse forgets to copy the default apps (ROOT, examples, etc.) when it creates a Tomcat folder inside the Eclipse workspace.

• Go to C:\apache-tomcat-7.0.27\webapps, R-click on the ROOT folder and copy it.
• Then go to your Eclipse workspace, go to the .metadata folder, and search for "wtpwebapps". You should find something like your-eclipse-workspace.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps (or .../tmp1/wtpwebapps if you already had another server registered in Eclipse).
• Go to the wtpwebapps folder, right-click, and paste ROOT (say "yes" if asked if you want to merge/replace folders/files).
• Then reload localhost:8080 to see the Tomcat welcome page.

Since a new question has just been closed against this: you shouldn't create Thread objects yourself. Here's another way to do it:

public void method() {
    Executors.newSingleThreadExecutor().submit(() -> {
        // yourCode
    });
}

You should probably retain the executor service between calls though.

Use tqdm_notebook

from tqdm import tqdm_notebook as tqdm

x=[1,2,3,4,5]

for i in tqdm(range(0,len(x))):

    print(x[i])

JSON.stringify(...) solved my issues

Code that is built into shared libraries should normally be position-independent code, so that the shared library can readily be loaded at (more or less) any address in memory. The -fPIC option ensures that GCC produces such code.

Give Safe User Permission To Use Port 80

Remember, we do NOT want to run your applications as the root user, but there is a hitch: your safe user does not have permission to use the default HTTP port (80). You goal is to be able to publish a website that visitors can use by navigating to an easy to use URL like http://ip:port/

Unfortunately, unless you sign on as root, you’ll normally have to use a URL like http://ip:port - where port number > 1024.

A lot of people get stuck here, but the solution is easy. There a few options but this is the one I like. Type the following commands:

sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``

Now, when you tell a Node application that you want it to run on port 80, it will not complain.

Check this reference link

Take a look at limits.h. You can find the specific values for your compiler. INT_MIN and INT_MAX will be of interest.

if the link element is:

<a id="misc" href="#misc">Miscellaneous</a>

and the Miscellaneous category is bounded by something like:

<p id="miscCategory" name="misc">....</p>

you can use jQuery to do the desired effect:

<script type="text/javascript">
  $("#misc").click(function() {
    $("#miscCategory").animate({scrollTop: $("#miscCategory").offset().top});
  });
</script>

as far as I remember it correctly.. (though, I haven't tested it and wrote it from memory)

I've searched deep into the code, step by step into the following files:

https://github.com/sdepold/sequelize/blob/master/test/Model/destroy.js

https://github.com/sdepold/sequelize/blob/master/lib/model.js#L140

https://github.com/sdepold/sequelize/blob/master/lib/query-interface.js#L207-217

https://github.com/sdepold/sequelize/blob/master/lib/connectors/mysql/query-generator.js

What I found:

There isn't a deleteAll method, there's a destroy() method you can call on a record, for example:

Project.find(123).on('success', function(project) {
  project.destroy().on('success', function(u) {
    if (u && u.deletedAt) {
      // successfully deleted the project
    }
  })
})

There is an easy way of doing it in Node.js

var object1 = {name: "John"};
var object2 = {location: "San Jose"};

To combine/extend this we can use ... operator in ECMA6

var object1 = {name: "John"};_x000D_
var object2 = {location: "San Jose"};_x000D_
_x000D_
var result = {_x000D_
  ...object1,_x000D_
  ...object2_x000D_
}_x000D_
_x000D_
console.log(result)

Diagnose

If you have pip installed (you should have it until you use Python 3.5), list the installed Python packages, like this:

$ pip list | grep -i keras
Keras (1.1.0)

If you don’t see Keras, it means that the previous installation failed or is incomplete (this lib has this dependancies: numpy (1.11.2), PyYAML (3.12), scipy (0.18.1), six (1.10.0), and Theano (0.8.2).)

Consult the pip.log to see what’s wrong.

You can also display your Python path like this:

$ python3 -c 'import sys, pprint; pprint.pprint(sys.path)'
['',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python35.zip',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/plat-darwin',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/lib-dynload',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages']

Make sure the Keras library appears in the /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages path (the path is different on Ubuntu).

If not, try do uninstall it, and retry installation:

$ pip uninstall Keras

Use a virtualenv

It’s a bad idea to use and pollute your system-wide Python. I recommend using a virtualenv (see this guide).

The best usage is to create a virtualenv directory (in your home, for instance), and store your virtualenvs in:

cd virtualenv/
virtualenv -p python3.5 py-keras
source py-keras/bin/activate
pip install -q -U pip setuptools wheel

Then install Keras:

pip install keras

You get:

$ pip list
Keras (1.1.0)
numpy (1.11.2)
pip (8.1.2)
PyYAML (3.12)
scipy (0.18.1)
setuptools (28.3.0)
six (1.10.0)
Theano (0.8.2)
wheel (0.30.0a0)

But, you also need to install extra libraries, like Tensorflow:

$ python -c "import keras"
Using TensorFlow backend.
Traceback (most recent call last):
  ...
ImportError: No module named 'tensorflow'

The installation guide of TesnsorFlow is here: https://www.tensorflow.org/versions/r0.11/get_started/os_setup.html#pip-installation

The problem is

When a Scanner is closed, it will close its input source if the source implements the Closeable interface.

http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Scanner.html

Thus scan.close() closes System.in.

To fix it you can make

Scanner scan static and do not close it in PromptCustomerQty. Code below works.

public static void main (String[] args) {   

// Create a customer
// Future proofing the possabiltiies of multiple customers
Customer customer = new Customer("Will");

// Create object for each Product
// (Name,Code,Description,Price)
// Initalize Qty at 0
Product Computer = new Product("Computer","PC1003","Basic Computer",399.99); 
Product Monitor = new Product("Monitor","MN1003","LCD Monitor",99.99);
Product Printer = new Product("Printer","PR1003x","Inkjet Printer",54.23);

// Define internal variables 
// ## DONT CHANGE 
ArrayList<Product> ProductList = new ArrayList<Product>(); // List to store Products
String formatString = "%-15s %-10s %-20s %-10s %-10s %n"; // Default format for output

// Add objects to list
ProductList.add(Computer);
ProductList.add(Monitor);
ProductList.add(Printer);

// Ask users for quantities 
PromptCustomerQty(customer, ProductList);

// Ask user for payment method
PromptCustomerPayment(customer);

// Create the header
PrintHeader(customer, formatString);

// Create Body
PrintBody(ProductList, formatString);   
}

static Scanner scan;

public static void PromptCustomerQty(Customer customer, ArrayList<Product> ProductList)               {
// Initiate a Scanner
scan = new Scanner(System.in);

// **** VARIABLES ****
int qty = 0;

// Greet Customer
System.out.println("Hello " + customer.getName());

// Loop through each item and ask for qty desired
for (Product p : ProductList) {

    do {
    // Ask user for qty
    System.out.println("How many would you like for product: " + p.name);
    System.out.print("> ");

    // Get input and set qty for the object
    qty = scan.nextInt();

    }
    while (qty < 0); // Validation

    p.setQty(qty); // Set qty for object
    qty = 0; // Reset count
}

// Cleanup

}

public static void PromptCustomerPayment (Customer customer) {
// Variables
String payment = "";

// Prompt User
do {
System.out.println("Would you like to pay in full? [Yes/No]");
System.out.print("> ");

payment = scan.next();

} while ((!payment.toLowerCase().equals("yes")) && (!payment.toLowerCase().equals("no")));

// Check/set result
if (payment.toLowerCase() == "yes") {
    customer.setPaidInFull(true);
}
else {
    customer.setPaidInFull(false);
}
}

On a side note, you shouldn't use == for String comparision, use .equals instead.

This is an old post but regardless, you can also get boldface and italic characters by leveraging utf-32. There are even greek and math symbols that can be used as well as the roman alphabet.

If you only need the standard functionality of hide only with visibility:hidden to keep the current layout you can use the callback function of hide to alter the css in the tag. Hide docs in jquery

An example :

$('#subs_selection_box').fadeOut('slow', function() {
      $(this).css({"visibility":"hidden"});
      $(this).css({"display":"block"});
});

This will use the normal cool animation to hide the div, but after the animation finish you set the visibility to hidden and display to block.

An example : http://jsfiddle.net/bTkKG/1/

I know you didnt want the $("#aa").css() solution, but you did not specify if it was because using only the css() method you lose the animation.

For 3d graphics applications the lwjgl.util vector implementation out-performed above mentioned jblas by a factor of about 3.

I have done 1 million matrix multiplications of a vec4 with a 4x4 matrix.

lwjgl finished in about 18ms, jblas required about 60ms.

(I assume, that the JNI approach is not very suitable for fast successive application of relatively small multiplications. Since the translation/mapping may take more time than the actual execution of the multiplication.)

Why not just use ToString?

public string generateID()
{
    return Guid.NewGuid().ToString("N");
}

If you would like it to be based on a URL, you could simply do the following:

public string generateID(string sourceUrl)
{
    return string.Format("{0}_{1:N}", sourceUrl, Guid.NewGuid());
}

If you want to hide the URL, you could use some form of SHA1 on the sourceURL, but I'm not sure what that might achieve.

By using this query you can see all open transactions.

see 5.5.x with the integrated OPcache module, volatile in a shared memory, much more performance and the dynamism principle of php remain untouched.

http://www.php.net/manual/en/opcache.installation.php

float 7 digits of precision

double has about 15 digits of precision

decimal has about 28 digits of precision

If you need better accuracy, use double instead of float. In modern CPUs both data types have almost the same performance. The only benifit of using float is they take up less space. Practically matters only if you have got many of them.

I found this is interesting. What Every Computer Scientist Should Know About Floating-Point Arithmetic

The best analogy I can think of is the surgeon and his assistant(s) in an operation theater, where the surgeon is the main person and his assistant who provides the various surgical components when he needs it so that the surgeon can concentrate on the one thing he does best (surgery). Without the assistant the surgeon has to get the components himself every time he needs one.

DI for short, is a technique to remove a common additional responsibility (burden) on components to fetch the dependent components, by providing them to it.

DI brings you closer to the Single Responsibility (SR) principle, like the surgeon who can concentrate on surgery.

When to use DI : I would recommend using DI in almost all production projects ( small/big), particularly in ever changing business environments :)

Why : Because you want your code to be easily testable, mockable etc so that you can quickly test your changes and push it to the market. Besides why would you not when you there are lots of awesome free tools/frameworks to support you in your journey to a codebase where you have more control.

I know this is an old answer but for others searching for this; in your CSS try:

background-size: auto 100%;

UPDATED ANSWER:

Old answer, correct method nowadays is to use jQuery's .prop(). IE, element.prop("selected", true)

OLD ANSWER:

Use this instead:

$("#routetype option[value='quietest']").attr("selected", "selected");

Fiddle'd: http://jsfiddle.net/x3UyB/4/

but on the other hand it creates a completely useless list of integers just to loop over them. Isn't it a waste of memory, especially as far as big numbers of iterations are concerned?

That is what xrange(n) is for. It avoids creating a list of numbers, and instead just provides an iterator object.

In Python 3, xrange() was renamed to range() - if you want a list, you have to specifically request it via list(range(n)).

Check your server's Java version. Happened to me because my Weblogic 10.3.6 was on JDK 1.7.0_75 which was on TLSv1. The rest endpoint I was trying to consume was shutting down anything below TLSv1.2.

By default Weblogic was trying to negotiate the strongest shared protocol. See details here: Issues with setting https.protocols System Property for HTTPS connections.

I added verbose SSL logging to identify the supported TLS. This indicated TLSv1 was being used for the handshake.
-Djavax.net.debug=ssl:handshake:verbose:keymanager:trustmanager -Djava.security.debug=access:stack

I resolved this by pushing the feature out to our JDK8-compatible product, JDK8 defaults to TLSv1.2. For those restricted to JDK7, I also successfully tested a workaround for Java 7 by upgrading to TLSv1.2. I used this answer: How to enable TLS 1.2 in Java 7

The question is already answered, Updating answer to add the PyCharm bin directory to $PATH var, so that pycharm editor can be opened from anywhere(path) in terminal.

nano .bashrc

export PATH="<path-to-unpacked-pycharm-installation-directory>/bin:$PATH"

pycharm.sh

For me the issue was about a comma not in the filename but as below: -

Response.ok(streamingOutput,MediaType.APPLICATION_OCTET_STREAM_TYPE).header("content-disposition", "attachment, filename=your_file_name").build();

I accidentally put a comma after attachment. Got it resolved by replacing comma with a semicolon.

const filteredObject = Object.fromEntries(Object.entries(originalObject).filter(([key, value]) => key !== uuid))

with parse.JSON

var obj = jQuery.parseJSON( '{ "name": "John" }' );
alert( obj.name === "John" );

Thanks,Bruno for giving me heads up on Common Name and Subject Alternative Name. As we figured out certificate was generated with CN with DNS name of network and asked for regeneration of new certificate with Subject Alternative Name entry i.e. san=ip:10.0.0.1. which is the actual solution.

But, we managed to find out a workaround with which we can able to run on development phase. Just add a static block in the class from which we are making ssl connection.

static {
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()
        {
            public boolean verify(String hostname, SSLSession session)
            {
                // ip address of the service URL(like.23.28.244.244)
                if (hostname.equals("23.28.244.244"))
                    return true;
                return false;
            }
        });
}

If you happen to be using Java 8, there is a much slicker way of achieving the same result:

static {
    HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> hostname.equals("127.0.0.1"));
}

this is my solution

JTextField username = new JTextField();
JTextField password = new JPasswordField();
Object[] message = {
    "Username:", username,
    "Password:", password
};

int option = JOptionPane.showConfirmDialog(null, message, "Login", JOptionPane.OK_CANCEL_OPTION);
if (option == JOptionPane.OK_OPTION) {
    if (username.getText().equals("h") && password.getText().equals("h")) {
        System.out.println("Login successful");
    } else {
        System.out.println("login failed");
    }
} else {
    System.out.println("Login canceled");
}

Important things for Java benchmarks are:

• Warm up the JIT first by running the code several times before timing it
• Make sure you run it for long enough to be able to measure the results in seconds or (better) tens of seconds
• While you can't call System.gc() between iterations, it's a good idea to run it between tests, so that each test will hopefully get a "clean" memory space to work with. (Yes, gc() is more of a hint than a guarantee, but it's very likely that it really will garbage collect in my experience.)
• I like to display iterations and time, and a score of time/iteration which can be scaled such that the "best" algorithm gets a score of 1.0 and others are scored in a relative fashion. This means you can run all algorithms for a longish time, varying both number of iterations and time, but still getting comparable results.

I'm just in the process of blogging about the design of a benchmarking framework in .NET. I've got a couple of earlier posts which may be able to give you some ideas - not everything will be appropriate, of course, but some of it may be.

try adding this to your js function:

    var outputvar = document.getElementById("your_div_id_inside_html_form");
    outputvar.innerHTML='<input id=id_to_send_to_php value='+your_js_var+'>';

Later in html:

    <div id="id_you_choosed_for_outputvar"></div>

this div will contain the js var to be passed through a form to another js function or to php, remember to place it inside your html form!. This solution is working fine for me.

In your specific geolocation case you can try adding the following to function showPosition(position):

    var outputlon = document.getElementById("lon1");
    outputlon.innerHTML = '<input id=lon value='+lon+'>';
    var outputlat = document.getElementById("lat1");
    outputlat.innerHTML = '<input id=lat value='+lat+'>';  

later add these div to your html form:

<div id=lat1></div>
<div id=lon1></div>

In these div you'll get latitude and longitude as input values for your php form, you would better hide them using css (show only the marker on a map if used) in order to avoid users to change them before to submit, and set your database to accept float values with lenght 10,7.

Hope this will help.

You can do that but the changes will affect for new data that is inserted on the database. On the long run follow as suggested above.

Also there are certain tricks you can override the collation, such as parameters for stored procedures or functions, alias data types, and variables are assigned the default collation of the database. To change the collation of an alias type, you must drop the alias and re-create it.

You can override the default collation of a literal string by using the COLLATE clause. If you do not specify a collation, the literal is assigned the database default collation. You can use DATABASEPROPERTYEX to find the current collation of the database.

You can override the server, database, or column collation by specifying a collation in the ORDER BY clause of a SELECT statement.

What I did is moved the dependencies list to the end of

#Pods for <app>

In Podfile. Like this:

    # Uncomment the next line to define a global platform for your project
    # platform :ios, '9.0'

    target '<app>' do
    # Comment the next line if you don't want to use dynamic frameworks
    use_frameworks!

  # Pods for <app>

  target '<app>Tests' do
    inherit! :search_paths
    # Pods for testing
  end

  target '<app>UITests' do
    inherit! :search_paths
    # Pods for testing
  end

    pod 'Firebase/Core'
    pod 'Firebase/Database'

end

You don't want to stretch the span in height?
You have the possiblity to affect one or more flex-items to don't stretch the full height of the container.

To affect all flex-items of the container, choose this:
You have to set align-items: flex-start; to div and all flex-items of this container get the height of their content.

div {_x000D_
  align-items: flex-start;_x000D_
  background: tan;_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
}_x000D_
span {_x000D_
  background: red;_x000D_
}

<div>_x000D_
  <span>This is some text.</span>_x000D_
</div>

To affect only a single flex-item, choose this:
If you want to unstretch a single flex-item on the container, you have to set align-self: flex-start; to this flex-item. All other flex-items of the container aren't affected.

div {_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
  background: tan;_x000D_
}_x000D_
span.only {_x000D_
  background: red;_x000D_
  align-self:flex-start;_x000D_
}_x000D_
span {_x000D_
    background:green;_x000D_
}

<div>_x000D_
  <span class="only">This is some text.</span>_x000D_
  <span>This is more text.</span>_x000D_
</div>

Why is this happening to the span?
The default value of the property align-items is stretch. This is the reason why the span fill the height of the div.

Difference between baseline and flex-start?
If you have some text on the flex-items, with different font-sizes, you can use the baseline of the first line to place the flex-item vertically. A flex-item with a smaller font-size have some space between the container and itself at top. With flex-start the flex-item will be set to the top of the container (without space).

div {_x000D_
  align-items: baseline;_x000D_
  background: tan;_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
}_x000D_
span {_x000D_
  background: red;_x000D_
}_x000D_
span.fontsize {_x000D_
  font-size:2em;_x000D_
}

<div>_x000D_
  <span class="fontsize">This is some text.</span>_x000D_
  <span>This is more text.</span>_x000D_
</div>

You can find more information about the difference between baseline and flex-start here:

man ssh gives me this options would could be useful.

-i identity_file Selects a file from which the identity (private key) for RSA or DSA authentication is read. The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for pro- tocol version 2. Identity files may also be specified on a per- host basis in the configuration file. It is possible to have multiple -i options (and multiple identities specified in config- uration files).

So you could create an alias in your bash config with something like

alias ssh="ssh -i /path/to/private_key"

I haven't looked into a ssh configuration file, but like the -i option this too could be aliased

-F configfile Specifies an alternative per-user configuration file. If a configuration file is given on the command line, the system-wide configuration file (/etc/ssh/ssh_config) will be ignored. The default for the per-user configuration file is ~/.ssh/config.

Find and download old SDK. Older SDKs are found here.

I have copied the xcode.app directory as Xcode_4.6.3.app.

Now you can test and debug in both xcode versions. You have to run them from the corresponding folders or create shortcuts in your desktop. When building from command line give the parameter as iPhoneOS6.1 instead of iPhoneOS7.0

This worked great for me in Xcode5 and iOS.

Go to into Xcode5's SDK dir. Its usually located at:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs

Add a symbolic link to the old SDK like this:

sudo ln -s /Applications/Xcode_4.6.3.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk iPhoneOS6.1.sdk

Or more accurately from anywhere in the command line,

sudo ln -s /Applications/Xcode_4.6.3.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk  /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk

For something really basic use this:

<a href="#middle">Go To Middle</a>

Or for something simple in javascript check out this jQuery plugin ScrollTo. Quite useful for scrolling smoothly.

An alternative way to code Brettski's answer, with which I otherwise agree entirely, might be

With New FileSystemObject
    If .FileExists(yourFilePath) Then
        .DeleteFile yourFilepath
    End If
End With

Same effect but fewer (well, none at all) variable declarations.

The FileSystemObject is a really useful tool and well worth getting friendly with. Apart from anything else, for text file writing it can actually sometimes be faster than the legacy alternative, which may surprise a few people. (In my experience at least, YMMV).

Use the load event:

img = new Image();

img.onload = function(){
  // image  has been loaded
};

img.src = image_url;

Also have a look at:

• Preloading and the JavaScript Image() object

I'm searched many answers that suggest me to type in cmd:

set path = "%path%;c:program files\java\jdk1.7.0\bin"

but this is WRONG!

the right solution is that you leave "set" and just type

path = %path%;c:program files\java\jdk1.7.0\bin

P/s: of course you have to replace "jdk1.7.0" folder by your current java version folder. This works well on win 7 32bit, but I think it also works on win 8 - try it!

 $('input.theclass[type=checkbox]').each(function () {
   var sThisVal = (this.checked ? $(this).val() : "");
 });

I had mostly the same problem and ended up a a different solution that makes this type of problem trivial to query.

I have a table of sensor data (1 minute data from about 30 sensors)

SensorReadings->(timestamp,value,idSensor)

and I have a sensor table that has lots of mostly static stuff about the sensor but the relevant fields are these:

Sensors->(idSensor,Description,tvLastUpdate,tvLastValue,...)

The tvLastupdate and tvLastValue are set in a trigger on inserts to the SensorReadings table. I always have direct access to these values without needing to do any expensive queries. This does denormalize slightly. The query is trivial:

SELECT idSensor,Description,tvLastUpdate,tvLastValue 
FROM Sensors

I use this method for data that is queried often. In my case I have a sensor table, and a large event table, that have data coming in at the minute level AND dozens of machines are updating dashboards and graphs with that data. With my data scenario the trigger-and-cache method works well.

Have you considered using:

where('date', '<', '2014-08-11')

You should avoid using the DATE() function on indexed columns in MySQL, as this prevents the engine from using the index.

UPDATE

As there seems to be some disagreement about the importance of DATE() and indexes, I have created a fiddle that demonstrates the difference, see POSSIBLE KEYS.

I've received the same error when working in a Spring Boot Application because when running as Spring Boot, it's easy to do localhost:8080/hello/World but when you've built the artifact and deployed to Tomcat, then you need to switch to using localhost:8080/<artifactName>/hello/World

Decision tree:

1. Frameworks like Qt and SWT need native DLLs. So you have to ask yourself: Are all necessary platforms supported? Can you package the native DLLs with your app?

   See here, how to do this for SWT.

   If you have a choice here, you should prefer Qt over SWT. Qt has been developed by people who understand UI and the desktop while SWT has been developed out of necessity to make Eclipse faster. It's more a performance patch for Java 1.4 than a UI framework. Without JFace, you're missing many major UI components or very important features of UI components (like filtering on tables).

   If SWT is missing a feature that you need, the framework is somewhat hostile to extending it. For example, you can't extend any class in it (the classes aren't final, they just throw exceptions when the package of this.getClass() isn't org.eclipse.swt and you can't add new classes in that package because it's signed).

2. If you need a native, pure Java solution, that leaves you with the rest. Let's start with AWT, Swing, SwingX - the Swing way.

   AWT is outdated. Swing is outdated (maybe less so but not much work has been done on Swing for the past 10 years). You could argue that Swing was good to begin with but we all know that code rots. And that's especially true for UIs today.

   That leaves you with SwingX. After a longer period of slow progress, development has picked up again. The major drawback with Swing is that it hangs on to some old ideas which very kind of bleeding edge 15 years ago but which feel "clumsy" today. For example, the table views do support filtering and sorting but you still have to configure this. You'll have to write a lot of boiler plate code just to get a decent UI that feels modern.

   Another weak area is theming. As of today, there are a lot of themes around. See here for a top 10. But some are slow, some are buggy, some are incomplete. I hate it when I write a UI and users complain that something doesn't work for them because they selected an odd theme.

3. JGoodies is another layer on top of Swing, like SwingX. It tries to make Swing more pleasant to use. The web site looks great. Let's have a look at the tutorial ... hm ... still searching ... hang on. It seems that there is no documentation on the web site at all. Google to the rescue. Nope, no useful tutorials at all.

   I'm not feeling confident with a UI framework that tries so hard to hide the documentation from potential new fans. That doesn't mean JGoodies is bad; I just couldn't find anything good to say about it but that it looks nice.

4. JavaFX. Great, stylish. Support is there but I feel it's more of a shiny toy than a serious UI framework. This feeling roots in the lack of complex UI components like tree tables. There is a webkit-based component to display HTML.

   When it was introduced, my first thought was "five years too late." If your aim is a nice app for phones or web sites, good. If your aim is professional desktop application, make sure it delivers what you need.

5. Pivot. First time I heard about it. It's basically a new UI framework based on Java2D. So I gave it a try yesterday. No Swing, just tiny bit of AWT (new Font(...)).

   My first impression was a nice one. There is an extensive documentation that helps you getting started. Most of the examples come with live demos (Note: You must have Java enabled in your web browser; this is a security risk) in the web page, so you can see the code and the resulting application side by side.

   In my experience, more effort goes into code than into documentation. By looking at the Pivot docs, a lot of effort must have went into the code. Note that there is currently a bug which prevents some of the examples to work (PIVOT-858) in your browser.

   My second impression of Pivot is that it's easy to use. When I ran into a problem, I could usually solve it quickly by looking at an example. I'm missing a reference of all the styles which each component supports, though.

   As with JavaFX, it's missing some higher level components like a tree table component (PIVOT-306). I didn't try lazy loading with the table view. My impression is that if the underlying model uses lazy loading, then that's enough.

   Promising. If you can, give it a try.

You can pass in a pointer to a time_t object that time will fill up with the current time (and the return value is the same one that you pointed to). If you pass in NULL, it just ignores it and merely returns a new time_t object that represents the current time.

Nb:time(&timer); is equivalent to timer = time(NULL);

If you're a homebrew user instead of macports, homebrew has an ant recipe.

brew install ant

First, checkout to your Branch3:

git checkout Branch3

Then merge the Branch1:

git merge Branch1

And if you want the updated commits of Branch1 on Branch2, you are probaly looking for git rebase

git checkout Branch2
git rebase Branch1

This will update your Branch2 with the latest updates of Branch1.

Variable set outside __init__ belong to the class. They're shared by all instances.

Variables created inside __init__ (and all other method functions) and prefaced with self. belong to the object instance.

I have used the following:

public static double Index2Freq(int i, double samples, int nFFT) {
  return (double) i * (samples / nFFT / 2.);
}

public static int Freq2Index(double freq, double samples, int nFFT) {
  return (int) (freq / (samples / nFFT / 2.0));
}

The inputs are:

• i: Bin to access
• samples: Sampling rate in Hertz (i.e. 8000 Hz, 44100Hz, etc.)
• nFFT: Size of the FFT vector

try this

public static final Pattern EMAIL_ADDRESS_PATTERN = Pattern.compile(

              "[a-zA-Z0-9\\+\\.\\_\\%\\-\\+]{1,256}" +
              "\\@" +
              "[a-zA-Z0-9][a-zA-Z0-9\\-]{0,64}" +
              "(" +
              "\\." +
              "[a-zA-Z0-9][a-zA-Z0-9\\-]{0,25}" +
              ")+"
          );

and in tne edit text

final String emailText = email.getText().toString();
EMAIL_ADDRESS_PATTERN.matcher(emailText).matches()

A regular for each will do:

foreach (var item in collection)
{
    // do your stuff   
}

For Windows, you have the problem of how to strip the executable from the result of GetModuleFileName(). The Windows API call PathRemoveFileSpec() that Nate used for that purpose in his answer changed between Windows 8 and its predecessors. So how to remain compatible with both and safe? Luckily, there's C++17 (or Boost, if you're using an older compiler). I do this:

#include <windows.h>
#include <string>
#include <filesystem>
namespace fs = std::experimental::filesystem;

// We could use fs::path as return type, but if you're not aware of
// std::experimental::filesystem, you probably handle filenames
// as strings anyway in the remainder of your code.  I'm on Japanese
// Windows, so wide chars are a must.
std::wstring getDirectoryWithCurrentExecutable()
{
    int size = 256;
    std::vector<wchar_t> charBuffer;
    // Let's be safe, and find the right buffer size programmatically.
    do {
        size *= 2;
        charBuffer.resize(size);
        // Resize until filename fits.  GetModuleFileNameW returns the
        // number of characters written to the buffer, so if the
        // return value is smaller than the size of the buffer, it was
        // large enough.
    } while (GetModuleFileNameW(NULL, charBuffer.data(), size) == size);
    // Typically: c:/program files (x86)/something/foo/bar/exe/files/win64/baz.exe
    // (Note that windows supports forward and backward slashes as path
    // separators, so you have to be careful when searching through a path
    // manually.)

    // Let's extract the interesting part:
    fs::path path(charBuffer.data());  // Contains the full path including .exe
    return path.remove_filename()  // Extract the directory ...
               .w_str();           // ... and convert to a string.
}

docker stop CONTAINER_ID & docker rm -v CONTAINER_ID

Here's an option if you have multiple records for each Customer and are looking for the latest balance for each (say they are dated records):

SELECT ID, BALANCE FROM (
    SELECT ROW_NUMBER() OVER (PARTITION BY ID ORDER BY DateModified DESC) as RowNum, ID, BALANCE
    FROM CUSTOMERS
) C
WHERE RowNum = 1
