Easy:

print my_queryset.query

For example:

from django.contrib.auth.models import User
print User.objects.filter(last_name__icontains = 'ax').query

It should also be mentioned that if you have DEBUG = True, then all of your queries are logged, and you can get them by accessing connection.queries:

from django.db import connections
connections['default'].queries

The django debug toolbar project uses this to present the queries on a page in a neat manner.

Homebrew and macports both solve the same problem - that is the installation of common libraries and utilities that are not bundled with osx.

Typically these are development related libraries and the most common use of these tools is for developers working on osx.

They both need the xcode command line tools installed (which you can download separately from https://developer.apple.com/), and for some specific packages you will need the entire xcode IDE installed.

xcode can be installed from the mac app store, its a free download but it takes a while since its around 5GB (if I remember correctly).

macports is an osx version of the port utility from BSD (as osx is derived from BSD, this was a natural choice). For anyone familiar with any of the BSD distributions, macports will feel right at home.

One major difference between homebrew and macports; and the reason I prefer homebrew is that it will not overwrite things that should be installed "natively" in osx. This means that if there is a native package available, homebrew will notify you instead of overwriting it and causing problems further down the line. It also installs libraries in the user space (thus, you don't need to use "sudo" to install things). This helps when getting rid of libraries as well since everything is in a path accessible to you.

homebrew also enjoys a more active user community and its packages (called formulas) are updated quite often.

macports does not overwrite native OSX packages - it supplies its own version - This is the main reason I prefer macports over home-brew, you need to be certain of what you are using and Apple's change at different times to the ports and have been know to be years behind updates in some projects

Can you give a reference showing that macports overwrites native OS X packages? As far as I can tell, all macports installation happens in /opt/local

Perhaps I should clarify - I did not say anywhere in my answer that macports overwrites OSX native packages. They both install items separately.

Homebrew will warn you when you should install things "natively" (using the library/tool's preferred installer) for better compatibility. This is what I meant. It will also use as many of the local libraries that are available in OS X. From the wiki:

We really don’t like dupes in Homebrew/homebrew

However, we do like dupes in the tap!

Stuff that comes with OS X or is a library that is provided by RubyGems, CPAN or PyPi should not be duped. There are good reasons for this:

• Duplicate libraries regularly break builds
• Subtle bugs emerge with duplicate libraries, and to a lesser extent, duplicate tools
• We want you to try harder to make your formula work with what OS X comes with

You can optionally overwrite the macosx supplied versions of utilities with homebrew.

Constructors are not inherited. They are called implicitly or explicitly by the child constructor.

The compiler creates a default constructor (one with no arguments) and a default copy constructor (one with an argument which is a reference to the same type). But if you want a constructor that will accept an int, you have to define it explicitly.

class A
{
public: 
    explicit A(int x) {}
};

class B: public A
{
public:
    explicit B(int x) : A(x) { }
};

UPDATE: In C++11, constructors can be inherited. See Suma's answer for details.

Try adding this rule to the top of your htaccess:

RewriteEngine On
RewriteRule ^404/?$ /pages/errors/404.php [L]

Then under that (or any other rules that you have):

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^ http://domain.com/404/ [L,R]

For me, Visual Studio on Mac doesn't support Node.js (editing and debugging) whereas Visual Studio Code does this very well.

This may not be the correct way to do it. But I have solved the problem using substring function.

Select max(start_ts), min(start_ts)from db where SUBSTR(start_ts, 0,9) ='13-may-2016'

using this I was able to retrieve the max and min timestamp.

Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.

1. Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .

2. if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .

3. if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .

4. after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).

5. if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.

6. If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.

7. If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.

8. If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.

   9. Restart your sql server instance after making any changes in property as some changes will require restart.

if you further face any difficulty then you need to provide more information about your web site and sql server .

I'm currently fighting with dropdowns and I'd like to share my experiences:

There are specific situations where <select> can't be used and must be 'emulated' with dropdown.

For example if you want to create bootstrap input groups, like Buttons with dropdowns (see http://getbootstrap.com/components/#input-groups-buttons-dropdowns). Unfortunately <select> is not supported in input groups, it will not be rendered properly.

Or does anybody solved this already? I would be very interested on the solution.

And to make it even more complicated, you can't use so simply $(this).text() to catch what user selected in dropdown if you're using glypicons or font awesome icons as content for dropdown. For example: <li id="someId"><a href="#0"><i class="fa fa-minus"></i></a></li> Because in this case there is no text and if you will add some then it will be also displayed in dropdown element and this is unwanted.

I found two possible solutions:

1) Use $(this).html() to get content of the selected <li> element and then to examine it, but you will get something like <a href="#0"><i class="fa fa-minus"></i></a> so you need to play with this to extract what you need.

2) Use $(this).text() and hide the text in element in hidden span: <li id="someId"><a href="#0"><i class="fa fa-minus"><span class="hidden">text</span></i></a></li>. For me this is simple and elegant solution, you can put any text you need, text will be hidden, and you don't need to do any transformations of $(this).html() result like in option 1) to get what you need.

I hope it's clear and can help somebody :-)

Try this:

android:text="Lorem Ipsum \nDolor Ait Amet \nLorem Ipsum"

That is because you have continuous text, means single long word without space. To break it add word-break: break-all;

.submenu div p {
    color:#fff;
    margin: 0;
    padding:0;
    width:100%;
    position: relative; word-break: break-all; background:red
}

DEMO

What worked for me now is:

CSS:

.right {
  text-align: right;
  margin-right: 1em;
}

.left {
  text-align: left;
  margin-left: 1em;
}

HTML:

<table width="100%">
  <tbody>
    <tr>
      <td class="left">
        <input id="abort" type="submit" name="abort" value="Back">
        <input id="save" type="submit" name="save" value="Save">
      </td>
      <td class="right">
        <input id="delegate" type="submit" name="delegate" value="Delegate">
        <input id="unassign" type="submit" name="unassign" value="Unassign">
        <input id="complete" type="submit" name="complete" value="Complete">
      </td>
    </tr>
  </tbody>
</table>

See the following fiddle:

If you are sorting strings that are mixed text & numbers, for example filenames of rolling logs then sorting with sort -n doesn't work as expected:

$ ls |sort -n
output.log.1
output.log.10
output.log.11
output.log.12
output.log.13
output.log.14
output.log.15
output.log.16
output.log.17
output.log.18
output.log.19
output.log.2
output.log.20
output.log.3
output.log.4
output.log.5
output.log.6
output.log.7
output.log.8
output.log.9

In that case option -V does the trick:

$ ls |sort -V
output.log.1
output.log.2
output.log.3
output.log.4
output.log.5
output.log.6
output.log.7
output.log.8
output.log.9
output.log.10
output.log.11
output.log.12
output.log.13
output.log.14
output.log.15
output.log.16
output.log.17
output.log.18
output.log.19
output.log.20

from man page:

   -V, --version-sort
          natural sort of (version) numbers within text

int (t.strftime("%s")) also works

THE only way to know if a variable is defined in current scope ($GLOBALS is not trustworthy) is array_key_exists( 'var_name', get_defined_vars() ).

If you need to retrieve more columns other than columns which are in group by then you can consider below query. Check it once whether it is performing well or not.

SELECT 
a.[CUSTOMER ID], 
a.[NAME], 
(select SUM(b.[AMOUNT]) from INV_DATA b
where b.[CUSTOMER ID] = a.[CUSTOMER ID]
GROUP BY b.[CUSTOMER ID]) AS [TOTAL AMOUNT]
FROM RES_DATA a

That's interesting, but as far as I know the answer is a firm no. I don't see why you need a nested ID, since you'll usually cross it with another element that has the same nested ID. If you don't there's no point, if you do there's still very little point.

The function name does not reflect the semantic of the function. In fact you do not append a character. You create a new character array that contains the original array plus the given character. So if you indeed need a function that appends a character to a character array I would write it the following way

bool AppendCharToCharArray( char *array, size_t n, char c )
{
    size_t sz = std::strlen( array );

    if ( sz + 1 < n ) 
    {
        array[sz] = c;
        array[sz + 1] = '\0';
    }       

    return ( sz + 1 < n );
} 

If you need a function that will contain a copy of the original array plus the given character then it could look the following way

char * CharArrayPlusChar( const char *array, char c )
{
    size_t sz = std::strlen( array );
    char *s = new char[sz + 2];

    std::strcpy( s, array );
    s[sz] = c;
    s[sz + 1] = '\0';

    return ( s );
} 

Use the SimpleDateFormat class parse() method. This method will return a Date object. You can then create a Calendar object for this Date and add 2 hours to it.

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = formatter.parse(theDateToParse);
Calendar cal = Calendar.getInstance();
cal.setTime(date);
cal.add(Calendar.HOUR_OF_DAY, 2);
cal.getTime(); // This will give you the time you want.

Usually substring_index does what you want:

mysql> select substring_index("[email protected]","@",-1);
+-----------------------------------------+
| substring_index("[email protected]","@",-1) |
+-----------------------------------------+
| gmail.com                               |
+-----------------------------------------+
1 row in set (0.00 sec)

That string2Bin can be written even more succinctly, and without any loops, to boot!

function string2Bin ( str ) {
    return str.split("").map( function( val ) { 
        return val.charCodeAt( 0 ); 
    } );
}

you can also mark the application as private if you don’t plan to put it in an actual repository.

{
  "name": "my-application",
  "version": "0.0.1",
  "private": true
}

Neither of these does anything useful. Use isalpha() or isdigit() from the standard library. They're in <ctype.h>.

Try :

SELECT count(*),group FROM table GROUP BY group ORDER BY group

to order by count descending do

SELECT count(*),group FROM table GROUP BY group ORDER BY count(*) DESC

This will group the results by the group column returning the group and the count and will return the order in group order

Removing the name from your binding will make it apply to all endpoints, and should produce the desired results. As so:

<services>
  <service name="Service.IService">
    <clear />
    <endpoint binding="basicHttpBinding" contract="Service.IService" />
  </service>
</services>
<bindings>
  <basicHttpBinding>
    <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
      <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
        maxArrayLength="16348" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
    </binding>
  </basicHttpBinding>
  <webHttpBinding>
    <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" />
  </webHttpBinding>
</bindings>

Also note that I removed the bindingConfiguration attribute from the endpoint node. Otherwise you would get an exception.

This same solution was found here : Problem with large requests in WCF

Typically for a use case which involves a sequence of pages and in the final stage or page we post the data to the server. In this scenario we need to maintain the state. In the below snippet we maintain the state on the client side

As mentioned in the above post. The session is created using the factory recipe.

Client side session can be maintained using the value provider recipe as well.

Please refer to my post for the complete details. session-tracking-in-angularjs

Let's take an example of a shopping cart which we need to maintain across various pages / angularjs controller.

In typical shopping cart we buy products on various product / category pages and keep updating the cart. Here are the steps.

Here we create the custom injectable service having a cart inside using the "value provider recipe".

'use strict';
function Cart() {
    return {
        'cartId': '',
        'cartItem': []
    };
}
// custom service maintains the cart along with its behavior to clear itself , create new , delete Item or update cart 

app.value('sessionService', {
    cart: new Cart(),
    clear: function () {
        this.cart = new Cart();
        // mechanism to create the cart id 
        this.cart.cartId = 1;
    },
    save: function (session) {
        this.cart = session.cart;
    },
    updateCart: function (productId, productQty) {
        this.cart.cartItem.push({
            'productId': productId,
            'productQty': productQty
        });
    },
    //deleteItem and other cart operations function goes here...
});

If you want to remove the glow from buttons in Bootstrap (which is not necessarily bad UX in my opinion), you'll need the following code:

.btn:focus, .btn:active:focus, .btn.active:focus{
  outline-color: transparent;
  outline-style: none;
}

You can use the DevExpress PdfDocumentProcessor.Print(PdfPrinterSettings) Method.

public void Print(string pdfFilePath)
{
      if (!File.Exists(pdfFilePath))
          throw new FileNotFoundException("No such file exists!", pdfFilePath);

      // Create a Pdf Document Processor instance and load a PDF into it.
      PdfDocumentProcessor documentProcessor = new PdfDocumentProcessor();
      documentProcessor.LoadDocument(pdfFilePath);

      if (documentProcessor != null)
      {
          PrinterSettings settings = new PrinterSettings();

          //var paperSizes = settings.PaperSizes.Cast<PaperSize>().ToList();
          //PaperSize sizeCustom = paperSizes.FirstOrDefault<PaperSize>(size => size.Kind == PaperKind.Custom); // finding paper size

          settings.DefaultPageSettings.PaperSize = new PaperSize("Label", 400, 600);

          // Print pdf
          documentProcessor.Print(settings);
      }
}

select m.definition from sys.all_sql_modules m inner join  sys.triggers t
on m.object_id = t.object_id 

Here just copy the definition and alter the trigger.

Else you can just goto SSMS and Expand the your DB and under Programmability expand Database Triggeres then right click on the specific trigger and click modify there also you can change.

You write like this-:

xAxis: {
        type: 'datetime',
        dateTimeLabelFormats: {
           day: '%d %b %Y'    //ex- 01 Jan 2016
        }
}

also check for other datetime format

http://api.highcharts.com/highcharts#xAxis.dateTimeLabelFormats

Since this came up on a Google search for "javascript get number of digits", I wanted to throw it out there that there is a shorter alternative to this that relies on internal casting to be done for you:

var int_number = 254;
var int_length = (''+int_number).length;

var dec_number = 2.12;
var dec_length = (''+dec_number).length;

console.log(int_length, dec_length);

Yields

3 4

Well, there are plenty of database tutorials online for java (what you're looking for is called JDBC). But if you are using plain servlets, you will have a class that extends HttpServlet and inside it you will have two methods that look like

public void doPost(HttpServletRequest req, HttpServletResponse resp){

}

and

public void doGet(HttpServletRequest req, HttpServletResponse resp){

}

One of them is called to handle GET operations and another is used to handle POST operations. You will then use the HttpServletRequest object to get the parameters that were passed as part of the form like so:

String name = req.getParameter("name");

Then, once you have the data from the form, it's relatively easy to add it to a database using a JDBC tutorial that is widely available on the web. I also suggest searching for a basic Java servlet tutorial to get you started. It's very easy, although there are a number of steps that need to be configured correctly.

You can achieve this by utilizing the jsPDF library and the toDataURL function.

I made a little demonstration:

TryGetValue is slightly faster, because FindEntry will only be called once.

How much faster? It depends on the dataset at hand. When you call the Contains method, Dictionary does an internal search to find its index. If it returns true, you need another index search to get the actual value. When you use TryGetValue, it searches only once for the index and if found, it assigns the value to your variable.

FYI: It's not actually catching an error.

It's calling:

public bool TryGetValue(TKey key, out TValue value)
{
    int index = this.FindEntry(key);
    if (index >= 0)
    {
        value = this.entries[index].value;
        return true;
    }
    value = default(TValue);
    return false;
}

ContainsKey is this:

public bool ContainsKey(TKey key)
{
    return (this.FindEntry(key) >= 0);
}

Try this:

var charArray = "this is a test".ToCharArray().Select(c=>c.ToString());

You can't do the second, because even if you use the remove() method on Iterator, you'll get an Exception thrown.

Personally, I would prefer the first for all Collection instances, despite the additional overheard of creating the new Collection, I find it less prone to error during edit by other developers. On some Collection implementations, the Iterator remove() is supported, on other it isn't. You can read more in the docs for Iterator.

The third alternative, is to create a new Collection, iterate over the original, and add all the members of the first Collection to the second Collection that are not up for deletion. Depending on the size of the Collection and the number of deletes, this could significantly save on memory, when compared to the first approach.

what platform are you running?..
if its unix, maybe adding

alias java='java -Xmx1g'  

to .bashrc (or similar) work

edit: Changing XmX to Xmx

You could use a bit of workaround by placing a sass file in folder what you would like to import and import all files in that file like this:

file path:main/current/_current.scss

@import "placeholders"; @import "colors";

and in next dir level file you just use import for file what imported all files from that dir:

file path:main/main.scss

@import "EricMeyerResetCSSv20"; @import "clearfix"; @import "current";

That way you have same number of files, like you are importing the whole dir. Beware of order, file that comes last will override the matching stiles.

May be I come later to answer but right now I'm facing with this... if helps there are one more solution (the way i solved it).

    var query2 = (
    from users in Repo.T_Benutzer
    join mappings in Repo.T_Benutzer_Benutzergruppen on mappings.BEBG_BE equals users.BE_ID into tmpMapp
    join groups in Repo.T_Benutzergruppen on groups.ID equals mappings.BEBG_BG into tmpGroups
    from mappings in tmpMapp.DefaultIfEmpty()
    from groups in tmpGroups.DefaultIfEmpty()
    select new
    {
         UserId = users.BE_ID
        ,UserName = users.BE_User
        ,UserGroupId = mappings.BEBG_BG
        ,GroupName = groups.Name
    }

);

By the way, I tried using the Stefan Steiger code which also helps but it was slower as hell.

According to this issue, the problem has been resolved and was likely released some time near the beginning of 2015. A quote from that same thread:

It is specifically related to calling notifyDataSetChanged. [...]

Btw, I strongly advice not using notifyDataSetChanged because it kills animations and performance. Also for this case, using specific notify events will work around the issue.

If you are still having issues with a recent version of the support library, I would suggest reviewing your calls to notifyXXX (specifically, your use of notifyDataSetChanged) inside your adapter, to make sure you are adhering to the (somewhat delicate/obscure) RecyclerView.Adapter contract. Also be sure to issue those notifications on the main thread.

It might be cause of a library, I faced it because of Glide.

It was

implementation 'com.github.bumptech.glide:glide:4.7.1'

So I added exclude group: "com.android.support" And it becomes

implementation ('com.github.bumptech.glide:glide:4.7.1') {
        exclude group: "com.android.support"
    }

var result_style = document.getElementById('result_tr').style;
result_style.display = '';

is working perfectly for me..

Searching for non-printable chars. TLDR; Executive Summary

1. search for control chars AND extended unicode
2. locale setting e.g. LC_ALL=C needed to make grep do what you might expect with extended unicode

SO the preferred non-ascii char finders:

$ perl -ne 'print "$. $_" if m/[\x00-\x08\x0E-\x1F\x80-\xFF]/' notes_unicode_emoji_test

as in top answer, the inverse grep:

$ grep --color='auto' -P -n "[^\x00-\x7F]" notes_unicode_emoji_test

as in top answer but WITH LC_ALL=C:

$ LC_ALL=C grep --color='auto' -P -n "[\x80-\xFF]" notes_unicode_emoji_test

. . more . . excruciating detail on this: . . .

I agree with Harvey above buried in the comments, it is often more useful to search for non-printable characters OR it is easy to think non-ASCII when you really should be thinking non-printable. Harvey suggests "use this: "[^\n -~]". Add \r for DOS text files. That translates to "[^\x0A\x020-\x07E]" and add \x0D for CR"

Also, adding -c (show count of patterns matched) to grep is useful when searching for non-printable chars as the strings matched can mess up terminal.

I found adding range 0-8 and 0x0e-0x1f (to the 0x80-0xff range) is a useful pattern. This excludes the TAB, CR and LF and one or two more uncommon printable chars. So IMHO a quite a useful (albeit crude) grep pattern is THIS one:

grep -c -P -n "[\x00-\x08\x0E-\x1F\x80-\xFF]" *

ACTUALLY, generally you will need to do this:

LC_ALL=C grep -c -P -n "[\x00-\x08\x0E-\x1F\x80-\xFF]" *

breakdown:

LC_ALL=C - set locale to C, otherwise many extended chars will not match (even though they look like they are encoded > 0x80)
\x00-\x08 - non-printable control chars 0 - 7 decimal
\x0E-\x1F - more non-printable control chars 14 - 31 decimal
\x80-1xFF - non-printable chars > 128 decimal
-c - print count of matching lines instead of lines
-P - perl style regexps

Instead of -c you may prefer to use -n (and optionally -b) or -l
-n, --line-number
-b, --byte-offset
-l, --files-with-matches

E.g. practical example of use find to grep all files under current directory:

LC_ALL=C find . -type f -exec grep -c -P -n "[\x00-\x08\x0E-\x1F\x80-\xFF]" {} + 

You may wish to adjust the grep at times. e.g. BS(0x08 - backspace) char used in some printable files or to exclude VT(0x0B - vertical tab). The BEL(0x07) and ESC(0x1B) chars can also be deemed printable in some cases.

UPDATE: I had to revisit this recently. And, YYMV depending on terminal settings/solar weather forecast BUT . . I noticed that grep was not finding many unicode or extended characters. Even though intuitively they should match the range 0x80 to 0xff, 3 and 4 byte unicode characters were not matched. ??? Can anyone explain this? YES. @frabjous asked and @calandoa explained that LC_ALL=C should be used to set locale for the command to make grep match.

e.g. my locale LC_ALL= empty

$ locale
LANG=en_IE.UTF-8
LC_CTYPE="en_IE.UTF-8"
.
.
LC_ALL=

grep with LC_ALL= empty matches 2 byte encoded chars but not 3 and 4 byte encoded:

$ grep -P -n "[\x00-\x08\x0E-\x1F\x80-\xFF]" notes_unicode_emoji_test
5:© copyright c2a9
7:call  underscore c2a0
9:CTRL
31:5 © copyright
32:7 call  underscore

grep with LC_ALL=C does seem to match all extended characters that you would want:

$ LC_ALL=C grep --color='auto' -P -n "[\x80-\xFF]" notes_unicode_emoji_test  
1:???? unicode dashes e28090
3:??? Heart With Arrow Emoji - Emojipedia == UTF8? f09f9298

7:call? underscore c2a0
11:LIVE??E! ?????????? ???? ?????????? ???? ?? ?? ???? ????  YEOW, mix of japanese and chars from other e38182 e38184 . . e0a487

34:52 LIVE??E! ?????????? ???? ?????????? ???? ?? ?? ???? ????  YEOW, mix of japanese and chars from other
81:LIVE??E! ?????????? ???? ?????????? ???? ?? ?? ???? ????  YEOW, mix of japanese and chars from other

THIS perl match (partially found elsewhere on stackoverflow) OR the inverse grep on the top answer DO seem to find ALL the ~weird~ and ~wonderful~ "non-ascii" characters without setting locale:

$ grep --color='auto' -P -n "[^\x00-\x7F]" notes_unicode_emoji_test

$ perl -ne 'print "$. $_" if m/[\x00-\x08\x0E-\x1F\x80-\xFF]/' notes_unicode_emoji_test  

1 -- unicode dashes e28090
3  Heart With Arrow Emoji - Emojipedia == UTF8? f09f9298
5 © copyright c2a9
7 call  underscore c2a0
9 CTRL-H CHARS URK URK URK 
11 LIVE-E! ????? ?? ????? ?? ? ? ?? ??  YEOW, mix of japanese and chars from other e38182 e38184 . . e0a487
29 1 -- unicode dashes
30 3  Heart With Arrow Emoji - Emojipedia == UTF8 e28090
31 5 © copyright
32 7 call  underscore
33 11 LIVE-E! ????? ?? ????? ?? ? ? ?? ??  YEOW, mix of japanese and chars from other
34 52 LIVE-E! ????? ?? ????? ?? ? ? ?? ??  YEOW, mix of japanese and chars from other
73 LIVE-E! ????? ?? ????? ?? ? ? ?? ??  YEOW, mix of japanese and chars from other

SO the preferred non-ascii char finders:

$ perl -ne 'print "$. $_" if m/[\x00-\x08\x0E-\x1F\x80-\xFF]/' notes_unicode_emoji_test

as in top answer, the inverse grep:

$ grep --color='auto' -P -n "[^\x00-\x7F]" notes_unicode_emoji_test

as in top answer but WITH LC_ALL=C:

$ LC_ALL=C grep --color='auto' -P -n "[\x80-\xFF]" notes_unicode_emoji_test

You can generate scripts to a file via SQL Server Management Studio, here are the steps:

1. Right click the database you want to generate scripts for (not the table) and select tasks - generate scripts
2. Next, select the requested table/tables, views, stored procedures, etc (from select specific database objects)
3. Click advanced - select the types of data to script
4. Click Next and finish

MSDN Generate Scripts

When generating the scripts, there is an area that will allow you to script, constraints, keys, etc. From SQL Server 2008 R2 there is an Advanced Option under scripting:

Actually, it is as simple as setting major and minor separately:

In [9]: plot([23, 456, 676, 89, 906, 34, 2345])
Out[9]: [<matplotlib.lines.Line2D at 0x6112f90>]

In [10]: yscale('log')

In [11]: grid(b=True, which='major', color='b', linestyle='-')

In [12]: grid(b=True, which='minor', color='r', linestyle='--')

The gotcha with minor grids is that you have to have minor tick marks turned on too. In the above code this is done by yscale('log'), but it can also be done with plt.minorticks_on().

For others in my situation, the solution was:

qmake -qt=qt5

This was on Ubuntu 14.04 after install qt5-qmake. qmake was a symlink to qtchooser which takes the -qt argument.

If you want to preserve column order in the index, here's a (very ugly) way to do that:

select table_name,
    index_name,
    array_agg(column_name)
from (
    select
        t.relname as table_name,
        i.relname as index_name,
        a.attname as column_name,
        unnest(ix.indkey) as unn,
        a.attnum
    from
        pg_class t,
        pg_class i,
        pg_index ix,
        pg_attribute a
    where
        t.oid = ix.indrelid
        and i.oid = ix.indexrelid
        and a.attrelid = t.oid
        and a.attnum = ANY(ix.indkey)
        and t.relkind = 'r'
        and t.relnamespace = <oid of the schema you're interested in>
    order by
        t.relname,
        i.relname,
        generate_subscripts(ix.indkey,1)) sb
where unn = attnum
group by table_name, index_name

column order is stored in the pg_index.indkey column, so I ordered by the subscripts from that array.

You can simply use one of the system dependent end-of-file indicators ( d for Unix/Linux/Ubuntu, z for windows) to make the while statement false. This should get you out of the loop nicely. :)

1. Go to the project folder and right click on it -> properties -> check off the read only box and click ok

2. Right-click on your project and select "Android Tools -> Fix Project Properties"

3. Right-click on your project and select "Properties -> Java Compiler", check "Enable project specific settings" and select 1.5 or 1.6 from "Compiler compliance settings" select box. (try all the levels one by one just in case)

4. Under Window -> Preferences -> Java -> Compiler, set Compiler compliance level to 1.6 or 1.5.

Hopefully it will settle the problem.

Try this:

Dim myarray As Variant
myarray = Array("Cat", "Dog", "Rabbit")

You can also specify columns on related model at the time of accessing it.

Post::first()->user()->get(['columns....']);

This may also work:

SELECT 
    COUNT(DISTINCT T.tag) as DistinctTag,
    COUNT(DISTINCT T2.tag) as DistinctPositiveTag
FROM Table T
    LEFT JOIN Table T2 ON T.tag = T2.tag AND T.entryID = T2.entryID AND T2.entryID > 0

You need the entryID condition in the left join rather than in a where clause in order to make sure that any items that only have a entryID of 0 get properly counted in the first DISTINCT.

It seems that the original test case is wrong.

I can confirm that the selector #my_parent_element * works with unbind().

Let's take the following html as an example:

<div id="#my_parent_element">
  <div class="div1">
    <div class="div2">hello</div>
    <div class="div3">my</div>
  </div>
  <div class="div4">name</div>
  <div class="div5">
    <div class="div6">is</div>
    <div class="div7">
      <div class="div8">marco</div>
      <div class="div9">(try and click on any word)!</div>
    </div>
  </div>
</div>
<button class="unbind">Now, click me and try again</button>

And the jquery bit:

$('.div1,.div2,.div3,.div4,.div5,.div6,.div7,.div8,.div9').click(function() {
  alert('hi!');
})
$('button.unbind').click(function() {
  $('#my_parent_element *').unbind('click');
})

Unpopular opinion from 2020:

When it comes to ASP.NET apps I still prefer WebClient over HttpClient because:

1. The modern implementation comes with async/awaitable task-based methods
2. Has smaller memory footprint and 2x-5x faster (other answers already mention that)
3. It's suggested to "reuse a single instance of HttpClient for the lifetime of your application". But ASP.NET has no "lifetime of application", only lifetime of a request.

tl;dr: You don't have to remove the slashes, you have nested JSON, and hence have to decode the JSON twice: DEMO (note I used double slashes in the example, because the JSON is inside a JS string literal).

I assume that your actual JSON looks like

{"data":"{\n \"taskNames\" : [\n \"01 Jan\",\n \"02 Jan\",\n \"03 Jan\",\n \"04 Jan\",\n \"05 Jan\",\n \"06 Jan\",\n \"07 Jan\",\n \"08 Jan\",\n \"09 Jan\",\n \"10 Jan\",\n \"11 Jan\",\n \"12 Jan\",\n \"13 Jan\",\n \"14 Jan\",\n \"15 Jan\",\n \"16 Jan\",\n \"17 Jan\",\n \"18 Jan\",\n \"19 Jan\",\n \"20 Jan\",\n \"21 Jan\",\n \"22 Jan\",\n \"23 Jan\",\n \"24 Jan\",\n \"25 Jan\",\n \"26 Jan\",\n \"27 Jan\"]}"}

I.e. you have a top level object with one key, data. The value of that key is a string containing JSON itself. This is usually because the server side code didn't properly create the JSON. That's why you see the \" inside the string. This lets the parser know that " is to be treated literally and doesn't terminate the string.

So you can either fix the server side code, so that you don't double encode the data, or you have to decode the JSON twice, e.g.

var data = JSON.parse(JSON.parse(json).data));

tl;dr If you want the length of a String type in terms of the number of human-readable characters, use countElements(). If you want to know the length in terms of the number of extended grapheme clusters, use endIndex. Read on for details.

The String type is implemented as an ordered collection (i.e., sequence) of Unicode characters, and it conforms to the CollectionType protocol, which conforms to the _CollectionType protocol, which is the input type expected by countElements(). Therefore, countElements() can be called, passing a String type, and it will return the count of characters.

However, in conforming to CollectionType, which in turn conforms to _CollectionType, String also implements the startIndex and endIndex computed properties, which actually represent the position of the index before the first character cluster, and position of the index after the last character cluster, respectively. So, in the string "ABC", the position of the index before A is 0 and after C is 3. Therefore, endIndex = 3, which is also the length of the string.

So, endIndex can be used to get the length of any String type, then, right?

Well, not always...Unicode characters are actually extended grapheme clusters, which are sequences of one or more Unicode scalars combined to create a single human-readable character.

let circledStar: Character = "\u{2606}\u{20DD}" // ??

circledStar is a single character made up of U+2606 (a white star), and U+20DD (a combining enclosing circle). Let's create a String from circledStar and compare the results of countElements() and endIndex.

let circledStarString = "\(circledStar)"
countElements(circledStarString) // 1
circledStarString.endIndex // 2

From Stack Overflow question What is the Python 3 equivalent of "python -m SimpleHTTPServer":

The following works for me:

python -m http.server [<portNo>]

Because I am using Python 3 the module SimpleHTTPServer has been replaced by http.server, at least in Windows.

os.system('command') returns a 16 bit number, which first 8 bits from left(lsb) talks about signal used by os to close the command, Next 8 bits talks about return code of command.

Refer my answer for more detail in What is the return value of os.system() in Python?

I add the changes directly to my virtualhost instead the global config of nginx, like this:

   server {
     client_max_body_size 100M;
     ...
   }

And then I change the params in php.ini, like the comments above:

   max_input_time = 24000
   max_execution_time = 24000
   upload_max_filesize = 12000M
   post_max_size = 24000M
   memory_limit = 12000M

and what you can not forget is to restart nginx and php-fpm, in centos 7 is like this:

  systemctl restart nginx
  systemctl restart php-fpm

With PowerShell 5 we now have the ability to create classes. Change your function into a class, and return will only return the object immediately preceding it. Here is a real simple example.

class test_class {
    [int]return_what() {
        Write-Output "Hello, World!"
        return 808979
    }
}
$tc = New-Object -TypeName test_class
$tc.return_what()

If this was a function the expected output would be

Hello World
808979

but as a class the only thing returned is the integer 808979. A class is sort of like a guarantee that it will only return the type declared or void.

I'm not sure why. But

oTable6.fnDraw();

Works for me. I put it in the next line.

You can also do it without the [xml] cast. (Although xpath is a world unto itself. https://www.w3schools.com/xml/xml_xpath.asp)

$xml = (select-xml -xpath / -path stack.xml).node
$xml.objects.object.property

Or just this, xpath is case sensitive. Both have the same output:

$xml = (select-xml -xpath /Objects/Object/Property -path stack.xml).node
$xml


Name         Type                                                #text

You can take advantage of Groovy features like with(), improvements to URLConnection, and simplified getters/setters:

GET:

String getResult = new URL('http://mytestsite/bloop').text

POST:

String postResult
((HttpURLConnection)new URL('http://mytestsite/bloop').openConnection()).with({
    requestMethod = 'POST'
    doOutput = true
    setRequestProperty('Content-Type', '...') // Set your content type.
    outputStream.withPrintWriter({printWriter ->
        printWriter.write('...') // Your post data. Could also use withWriter() if you don't want to write a String.
    })
    // Can check 'responseCode' here if you like.
    postResult = inputStream.text // Using 'inputStream.text' because 'content' will throw an exception when empty.
})

Note, the POST will start when you try to read a value from the HttpURLConnection, such as responseCode, inputStream.text, or getHeaderField('...').

solution is easy:

replace

 mask = (50  < df['heart rate'] < 101 &
            140 < df['systolic blood pressure'] < 160 &
            90  < df['dyastolic blood pressure'] < 100 &
            35  < df['temperature'] < 39 &
            11  < df['respiratory rate'] < 19 &
            95  < df['pulse oximetry'] < 100
            , "excellent", "critical")

by

mask = ((50  < df['heart rate'] < 101) &
        (140 < df['systolic blood pressure'] < 160) &
        (90  < df['dyastolic blood pressure'] < 100) &
        (35  < df['temperature'] < 39) &
        (11  < df['respiratory rate'] < 19) &
        (95  < df['pulse oximetry'] < 100)
        , "excellent", "critical")

To bring the existing answers together with an important clarification:

As stated, the problem with NAME=sam echo "$NAME" is that $NAME gets expanded by the current shell before assignment NAME=sam takes effect.

Solutions that preserve the original semantics (of the (ineffective) solution attempt NAME=sam echo "$NAME"):

Use either eval^[1] (as in the question itself), or printenv (as added by Aaron McDaid to heemayl's answer), or bash -c (from Ljm Dullaart's answer), in descending order of efficiency:

NAME=sam eval 'echo "$NAME"'  # use `eval` only if you fully control the command string
NAME=sam printenv NAME
NAME=sam bash -c 'echo "$NAME"'

^{printenv is not a POSIX utility, but it is available on both Linux and macOS/BSD.}

What this style of invocation (<var>=<name> cmd ...) does is to define NAME:

• as an environment variable
• that is only defined for the command being invoked.

In other words: NAME only exists for the command being invoked, and has no effect on the current shell (if no variable named NAME existed before, there will be none after; a preexisting NAME variable remains unchanged).

POSIX defines the rules for this kind of invocation in its Command Search and Execution chapter.

The following solutions work very differently (from heemayl's answer):

NAME=sam; echo "$NAME"
NAME=sam && echo "$NAME"

While they produce the same output, they instead define:

• a shell variable NAME (only) rather than an environment variable
  • if echo were a command that relied on environment variable NAME, it wouldn't be defined (or potentially defined differently from earlier).
• that lives on after the command.

Note that every environment variable is also exposed as a shell variable, but the inverse is not true: shell variables are only visible to the current shell and its subshells, but not to child processes, such as external utilities and (non-sourced) scripts (unless they're marked as environment variables with export or declare -x).

^{[1] Technically, bash is in violation of POSIX here (as is zsh): Since eval is a special shell built-in, the preceding NAME=sam assignment should cause the the variable $NAME to remain in scope after the command finishes, but that's not what happens.
However, when you run bash in POSIX compatibility mode, it is compliant.
dash and ksh are always compliant.
The exact rules are complicated, and some aspects are left up to the implementations to decide; again, see Command Search and Execution.
Also, the usual disclaimer applies: Use eval only on input you fully control or implicitly trust.}

If you have PHP 5.2 Joey's answer won't work. You need to extend PHP's DateTime class:

class ExDateTime extends DateTime{
    public static function createFromFormat($frmt,$time,$timezone=null){
        $v = explode('.', phpversion());
        if(!$timezone) $timezone = new DateTimeZone(date_default_timezone_get());
        if(((int)$v[0]>=5&&(int)$v[1]>=2&&(int)$v[2]>17)){
            return parent::createFromFormat($frmt,$time,$timezone);
        }
        return new DateTime(date($frmt, strtotime($time)), $timezone);
    }
}

and than you can use this class without problems:

ExDateTime::createFromFormat('d.m.Y G:i',$timevar);

Try the following code.

 TimeSpan CurrentTime = DateTime.Now.TimeOfDay;

Get the time of the day and assign it to TimeSpan variable.

To me, handling exception can be seen as business rule. Obviously, the first approach is unacceptable. The second one is better one and it might be 100% correct way IF the context says so. Now, for example, you are developing an Outlook Addin. If you addin throws unhandled exception, the outlook user might now know it since the outlook will not destroy itself because of one plugin failed. And you have hard time to figure out what went wrong. Therefore, the second approach in this case, to me, it is a correct one. Beside logging the exception, you might decide to display error message to user - i consider it as a business rule.

IF you want to filter with NOT IN for a subquery containg NULLs justcheck for not null

Machine code is binary (1's and 0's) code that can be executed directly by the CPU. If you open a machine code file in a text editor you would see garbage, including unprintable characters (no, not those unprintable characters ;) ).

Object code is a portion of machine code not yet linked into a complete program. It's the machine code for one particular library or module that will make up the completed product. It may also contain placeholders or offsets not found in the machine code of a completed program. The linker will use these placeholders and offsets to connect everything together.

Assembly code is plain-text and (somewhat) human read-able source code that mostly has a direct 1:1 analog with machine instructions. This is accomplished using mnemonics for the actual instructions, registers, or other resources. Examples include JMP and MULT for the CPU's jump and multiplication instructions. Unlike machine code, the CPU does not understand assembly code. You convert assembly code to machine code with the use of an assembler or a compiler, though we usually think of compilers in association with high-level programming language that are abstracted further from the CPU instructions.

Building a complete program involves writing source code for the program in either assembly or a higher level language like C++. The source code is assembled (for assembly code) or compiled (for higher level languages) to object code, and individual modules are linked together to become the machine code for the final program. In the case of very simple programs the linking step may not be needed. In other cases, such as with an IDE (integrated development environment) the linker and compiler may be invoked together. In other cases, a complicated make script or solution file may be used to tell the environment how to build the final application.

There are also interpreted languages that behave differently. Interpreted languages rely on the machine code of a special interpreter program. At the basic level, an interpreter parses the source code and immediately converts the commands to new machine code and executes them. Modern interpreters are now much more complicated: evaluating whole sections of source code at a time, caching and optimizing where possible, and handling complex memory management tasks.

One final type of program involves the use of a runtime-environment or virtual machine. In this situation, a program is first pre-compiled to a lower-level intermediate language or byte code. The byte code is then loaded by the virtual machine, which just-in-time compiles it to native code. The advantage here is the virtual machine can take advantage of optimizations available at the time the program runs and for that specific environment. A compiler belongs to the developer, and therefore must produce relatively generic (less-optimized) machine code that could run in many places. The runtime environment or virtual machine, however, is located on the end user's computer and therefore can take advantage of all the features provided by that system.

After installing Pillow, I was able to access imread as follows:

In [1]: import scipy.misc

In [2]: scipy.misc.imread
Out[2]: <function scipy.misc.pilutil.imread>

There are numerous methods of accomplishing this, which I'll detail with a few examples below.

Pure CSS (using only one colored image)

img.grayscale {
  filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0\'/></filter></svg>#grayscale"); /* Firefox 3.5+ */
  filter: gray; /* IE6-9 */
  -webkit-filter: grayscale(100%); /* Chrome 19+ & Safari 6+ */
}

img.grayscale:hover {

  -webkit-filter: grayscale(0%);

You can find an article related to this technique here.

Pure CSS (using a grayscale and colored images)

This approach requires two copies of an image: one in grayscale and the other in full color. Using the CSS :hover psuedoselector, you can update the background of your element to toggle between the two:

#yourimage { 
    background: url(../grayscale-image.png);
}
#yourImage:hover { 
    background: url(../color-image.png};
}

#google {_x000D_
  background: url('http://www.google.com/logos/keystroke10-hp.png');_x000D_
  height: 95px;_x000D_
  width: 275px;_x000D_
  display: block;_x000D_
  /* Optional for a gradual animation effect */_x000D_
  transition: 0.5s;_x000D_
}_x000D_
_x000D_
#google:hover {_x000D_
  background: url('https://graphics217b.files.wordpress.com/2011/02/logo1w.png');_x000D_
}

<a id='google' href='http://www.google.com'></a>

This could also be accomplished by using a Javascript-based hover effect such as jQuery's hover() function in the same manner.

Consider a Third-Party Library

The desaturate library is a common library that allows you to easily switch between a grayscale version and full-colored version of a given element or image.

Yup. :) You can use Hipify to convert CUDA code very easily to HIP code which can be compiled run on both AMD and nVidia hardware pretty good. Here are some links

GPUOpen very cool site by AMD that has tons of tools and software libraries to help with different aspects of GPU computing many of which work on both platforms

HIP Github Repository that shows the process to hipify

HIP GPUOpen Blog

The api will return the list in increments of 1000. Check the IsTruncated property to see if there are still more. If there are, you need to make another call and pass the last key that you got as the Marker property on the next call. You would then continue to loop like this until IsTruncated is false.

See this Amazon doc for more info: Iterating Through Multi-Page Results

Change the checkboxes so that the name includes the index inside the brackets:

<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>"> 

The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.

Thought I would supplement other answers with my own personal experience on this.

Recently I had an issue whereby two targets would build, and two would fail with the following error:

Code Sign error: No code signing identites found: No valid signing identities (i.e. certificate and private key pair) matching the team ID “XXXXXXXXXX” were found. CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 7.1'

This was despite having updated everything in Xcode and on the iOS Developer Center.

The hint was that the team ID shown in the build failure message about was out of date.

Sure enough, opening Xcode's project.pbxproj file in a Text editor found the old team id:

D29A93A318AB96440099C177 = {
        DevelopmentTeam = XXXXXXXXXX;
};

Incidentally, to get your project.pbxproj file, select your .xcodeproj file and do show contents as shown here:

Searching on the target Id D29A93A318AB96440099C177, I could see that it matched one of the failing targets:

targets = (
    F5E8B19A16E64505006F22D4 /* MyTarget1 */,
    93DB2342183F737100BEA69F /* MyTarget2 */,
    D29A93A318AB96440099C177 /* MyTarget3 */,
    D200F4B518AB968A00F58C21 /* MyTarget4 */,
    F5E8B1C016E64505006F22D4 /* MyTarget5 */,
    589FB35119114DED003D9350 /* MyTarget6 */,
);

In this case, MyTarget3. To resolve, a simple text search replaced the old team Id with the new correct Id. Problem solved.

To Summarise, hopefully your situation will be resolved using the answers above rather than delving into the complexities of Xcode's project file. However, if it doesn't, and the error shows an invalid team ID, then it's worth checking to see if that team ID is still around.

You do not specify why you think it is wrong but I can se two dangers:

BETWEEN can be implemented differently in different databases sometimes it is including the border values and sometimes excluding, resulting in that 1 and 31 of january would end up NOTHING. You should test how you database does this.

Also, if RATE_DATE contains hours also 2010-01-31 might be translated to 2010-01-31 00:00 which also would exclude any row with an hour other that 00:00.

Coming here from first Google hit:

You can turn off the behavior AND and warning by exporting GIT_DISCOVERY_ACROSS_FILESYSTEM=1.

On heroku, if you heroku config:set GIT_DISCOVERY_ACROSS_FILESYSTEM=1 the warning will go away.

It's probably because you are building a gem from source and the gemspec shells out to git, like many do today. So, you'll still get the warning fatal: Not a git repository (or any of the parent directories): .git but addressing that is for another day :)

My answer is a duplicate of: - comment GIT_DISCOVERY_ACROSS_FILESYSTEM problem when working with terminal and MacFusion

Here's an alternative following the last answer

declare @t tinyint,@v tinyint
set @t=23
set @v=232
Select replace(str(@t,4),' ','0'),replace(str(@t,5),' ','0')

This will work on any number and by varying the length of the str() function you can stipulate how many leading zeros you require. Provided of course that your string length is always >= maximum number of digits your number type can hold.

128M == 134217728, the number you are seeing.

The memory limit is working fine. When it says it tried to allocate 32 bytes, that the amount requested by the last operation before failing.

Are you building any huge arrays or reading large text files? If so, remember to free any memory you don't need anymore, or break the task down into smaller steps.

Thanks for the really useful script.

You may need to add the following modification to the code if your tables have non-convertable fields:

SET @ColumnName =
    (
        SELECT MIN(QUOTENAME(COLUMN_NAME))
        FROM    INFORMATION_SCHEMA.COLUMNS
        WHERE       TABLE_SCHEMA    = PARSENAME(@TableName, 2)
            AND TABLE_NAME  = PARSENAME(@TableName, 1)
            AND DATA_TYPE NOT IN ('text', 'image', 'ntext')                 
            AND QUOTENAME(COLUMN_NAME) > @ColumnName
    )

It is possible by recreating table.Its work for me please follow following step:

1. create temporary table using as select * from your table
2. drop your table, create your table using modify column type
3. now insert records from temp table to your newly created table
4. drop temporary table

do all above steps in worker thread to reduce load on uithread

echo '< span style = "font-color: #ff0000"> Movie List for {$key} 2013 </span>';

As @Sean said, fcntl() is largely standardized, and therefore available across platforms. The ioctl() function predates fcntl() in Unix, but is not standardized at all. That the ioctl() worked for you across all the platforms of relevance to you is fortunate, but not guaranteed. In particular, the names used for the second argument are arcane and not reliable across platforms. Indeed, they are often unique to the particular device driver that the file descriptor references. (The ioctl() calls used for a bit-mapped graphics device running on an ICL Perq running PNX (Perq Unix) of twenty years ago never translated to anything else anywhere else, for example.)

In my case I had an image in different folders (with same name) for supporting different dpi and device sizes. All images had same name except one of them. It was mistyped and once I renamed it like other names, it resolved my issue.

Its easy, just wrap it in a relative box like so:

<div class="relative">
 <div class="absolute">LOGO</div>
</div>

The relative box has a margin: 0 Auto; and, important, a width...

A few people have an example using setAttribute which I like. However it assumes you don't have any styles currently set. I would maybe do something like:

nFilter.setAttribute('style', nFilter.getAttribute('style') + ';width:330px;float:left;');

Or make it into a helper function like this:

function setStyle(el, css){
  el.setAttribute('style', el.getAttribute('style') + ';' + css);
}

setStyle(nFilter, 'width:330px;float:left;');

This makes sure that you can add styles to it continuously and it won't remove any style currently set by always appending to the current styles. It also adds an extra semi colon so that if there is a style ever missing one it will append another to make sure it is fully delimited.

Prefer EntityManagerFactory and EntityManager. They are defined by the JPA standard.

SessionFactory and Session are hibernate-specific. The EntityManager invokes the hibernate session under the hood. And if you need some specific features that are not available in the EntityManager, you can obtain the session by calling:

Session session = entityManager.unwrap(Session.class);

Use the mouse

Sometimes, the easiest way to edit a commandline is using a mouse. Some previous answers give a command to open your current line in your $EDITOR. For me (zhs with grml config) that combination is Alt+e. If you enable mouse in your editor, you can make use of it.

To enable mouse in Vim, add this to your ~/.vimrc

set mouse=a
set ttymouse=xterm2

If you then want to do a text selection in terminal (instead of passing the mouseclick to vim), hold Shift when you click; this is terminal specific, of course.

Sysadmins should not be afraid of the mouse.

I think the project you are looking for is: https://github.com/sarxos/webcam-capture (I'm the author)

There is an example working exactly as you've described - after it's run, the window appear where, after you press "Start" button, you can see live image from webcam device and save it to file after you click on "Snapshot" (source code available, please note that FPS counter in the corner can be disabled):

The project is portable (WinXP, Win7, Win8, Linux, Mac, Raspberry Pi) and does not require any additional software to be installed on the PC.

API is really nice and easy to learn. Example how to capture single image and save it to PNG file:

Webcam webcam = Webcam.getDefault();
webcam.open();
ImageIO.write(webcam.getImage(), "PNG", new File("test.png"));

To illustrate this, consider:

public interface FileOperation {
  void perform(File file) throws FileNotFoundException;
}

public class OpenOnly implements FileOperation {
  void perform(File file) throws FileNotFoundException {
    FileReader r = new FileReader(file);
  }
}

Suppose you then write:

public class OpenClose implements FileOperation {
  void perform(File file) throws FileNotFoundException {
    FileReader r = new FileReader(file);
    r.close();
  }
}

This will give you a compilation error, because r.close() throws an IOException, which is broader than FileNotFoundException.

To fix this, if you write:

public class OpenClose implements FileOperation {
  void perform(File file) throws IOException {
    FileReader r = new FileReader(file);
    r.close();
  }
}

You will get a different compilation error, because you are implementing the perform(...) operation, but throwing an exception not included in the interface's definition of the method.

Why is this important? Well a consumer of the interface may have:

FileOperation op = ...;
try {
  op.perform(file);
}
catch (FileNotFoundException x) {
  log(...);
}

If the IOException were allowed to be thrown, the client's code is nolonger correct.

Note that you can avoid this sort of issue if you use unchecked exceptions. (I am not suggesting you do or don't, that is a philosophical issue)

Use ThisWorkbook which will refer to the original workbook which holds the code.

Alternatively at code start

Dim Wb As Workbook
Set Wb = ActiveWorkbook

sample code that activates all open books before returning to ThisWorkbook

Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
    Wb2.Activate
Next
Wb.Activate
End Sub

You are mixing code that was compiled with /MD (use DLL version of CRT) with code that was compiled with /MT (use static CRT library). That cannot work, all source code files must be compiled with the same setting. Given that you use libraries that were pre-compiled with /MD, almost always the correct setting, you must compile your own code with this setting as well.

Project + Properties, C/C++, Code Generation, Runtime Library.

Beware that these libraries were probably compiled with an earlier version of the CRT, msvcr100.dll is quite new. Not sure if that will cause trouble, you may have to prevent the linker from generating a manifest. You must also make sure to deploy the DLLs you need to the target machine, including msvcr100.dll

I don't think this is possible (at least not without using some internals). And I don't think you would gain much by optimizing this.

Sometimes things might be simpler. I came here with the exact issue and tried all the suggestions. But later found that the problem was just the local file path was different and I was on a different folder. :-)

eg -

~/myproject/mygitrepo/app/$ git diff app/TestFile.txt

should have been

~/myproject/mygitrepo/app/$ git diff TestFile.txt

I had the same issue with Xcode... black screen on launching apps, no debugging and clicking would lock up Xcode.

I finally found the problem... following the lead that the simulator could not connect to Xcode I took a look at my etc/hosts file and found that months ago to solve a different issue I had edited the host file to map localhost to my fixed IP instead of the default... my value:

10.0.1.17 localhost

This should work since that is my IP, but changing it back to the default IP fixed Xcode...

127.0.0.1 localhost

Hope this helps.

This is the bash script to print commands for syncing two directories

dir1=/tmp/path_to_dir1
dir2=/tmp/path_to_dir2
diff -rq $dir1 $dir2 | sed -e "s|Only in $dir2\(.*\): \(.*\)|cp -r $dir2\1/\2 $dir1\1|" |  sed -e "s|Only in $dir1\(.*\): \(.*\)|cp -r $dir1\1/\2 $dir2\1|" 

CSS

:active denotes the interaction state (so for a button will be applied during press), :focus may be a better choice here. However, the styling will be lost once another element gains focus.

The final potential alternative using CSS would be to use :target, assuming the items being clicked are setting routes (e.g. anchors) within the page- however this can be interrupted if you are using routing (e.g. Angular), however this doesnt seem the case here.

.active:active {_x000D_
  color: red;_x000D_
}_x000D_
.focus:focus {_x000D_
  color: red;_x000D_
}_x000D_
:target {_x000D_
  color: red;_x000D_
}

<button class='active'>Active</button>_x000D_
<button class='focus'>Focus</button>_x000D_
<a href='#target1' id='target1' class='target'>Target 1</a>_x000D_
<a href='#target2' id='target2' class='target'>Target 2</a>_x000D_
<a href='#target3' id='target3' class='target'>Target 3</a>

Javascript / jQuery

As such, there is no way in CSS to absolutely toggle a styled state- if none of the above work for you, you will either need to combine with a change in your HTML (e.g. based on a checkbox) or programatically apply/remove a class using e.g. jQuery

$('button').on('click', function(){_x000D_
    $('button').removeClass('selected');_x000D_
    $(this).addClass('selected');_x000D_
});

button.selected{_x000D_
  color:red;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<button>Item</button><button>Item</button><button>Item</button>_x000D_
  

for those who expect a behaviour like the apache StringUtils.isBlank or Guava Strings.isNullOrEmpty :

if mystring and mystring.strip():
    print "not blank string"
else:
    print "blank string"

You should be able to use join, which joins on the index as default. Given your desired result, you must use outer as the join type.

>>> df1.join(df2, how='outer')
            V1  V2
A 1/1/2012  12  15
  2/1/2012  14 NaN
  3/1/2012 NaN  21
B 1/1/2012  15  24
  2/1/2012   8   9
C 1/1/2012  17 NaN
  2/1/2012   9 NaN
D 1/1/2012 NaN   7
  2/1/2012 NaN  16

Signature: _.join(other, on=None, how='left', lsuffix='', rsuffix='', sort=False) Docstring: Join columns with other DataFrame either on index or on a key column. Efficiently Join multiple DataFrame objects by index at once by passing a list.

This is what I like to do:

$files = array_values(array_filter(scandir($path), function($file) use ($path) { 
    return !is_dir($path . '/' . $file);
}));

foreach($files as $file){
    echo $file;
}

Use WebElement.send_keys method to simulate key typing.

name in the code (Username, Password) does not match actual name of the elements (username, password).

username = browser.find_element_by_name('username')
username.send_keys('user1')

password = browser.find_element_by_name('password')
password.send_keys('secret')

form = browser.find_element_by_id('loginForm')
form.submit()

# OR  browser.find_element_by_id('submit').click()

None of the above answers worked for me. I kept getting this error:

Copy-Item : Access is denied
+ CategoryInfo          : PermissionDenied: (\\192.168.1.100\Shared\test.txt:String) [Copy-Item], UnauthorizedAccessException>   
+ FullyQualifiedErrorId : ItemExistsUnauthorizedAccessError,Microsoft.PowerShell.Commands.CopyItemCommand

So this did it for me:

netsh advfirewall firewall set rule group="File and Printer Sharing" new enable=yes

Then from my host my machine in the Run box I just did this:

\\{IP address of nanoserver}\C$

Make a file SOMEFILENAME.udl then double click on it and set it up as an ODBC connection object, username, pwd, target server

Another MySQL option that may look more like Oracle's DECODE is a combination of FIELD and ELT. In the code that follows, FIELD() returns the argument list position of the string that matches Age. ELT() returns the string from ELTs argument list at the position provided by FIELD(). For example, if Age is 14, FIELD(Age, ...) returns 2 because 14 is the 2nd argument of FIELD (not counting Age). Then, ELT(2, ...) returns 'Fourteen', which is the 2nd argument of ELT (not counting the FIELD() argument). IFNULL returns the default AgeBracket if no match to Age is found in the list.

Select Name, IFNULL(ELT(FIELD(Age,
       13, 14, 15, 16, 17, 18, 19),'Thirteen','Fourteen','Fifteen','Sixteen',
       'Seventeen','Eighteen','Nineteen'),
       'Adult') AS AgeBracket
FROM Person

While I don't think this is the best solution to the question either in terms of performance or readability it is interesting as an exploration of MySQL's string functions. Keep in mind that FIELD's output does not seem to be case sensitive. I.e., FIELD('A','A') and FIELD('a','A') both return 1.

there should has a concurrent implemention of List interface supporting such operation.

try java.util.concurrent.CopyOnWriteArrayList.class

After you connect the UIButton that you want to change its background as an OUtlet to your ViewController.swift file you can use the following:

 yourUIButton.backgroundColor = UIColor.blue

I faced the same problem and solved it. Try to log in manually to your gmail account first. This issue is due to google has detected your gmail account has been abusing. E.g send a lot of emails over a short period of time.

You can use this code to insert some items into a combo box with text and value.

C#

private void ComboBox_SelectionChanged_1(object sender, SelectionChangedEventArgs e)
{
    combox.Items.Insert(0, "Copenhagen");
    combox.Items.Insert(1, "Tokyo");
    combox.Items.Insert(2, "Japan");
    combox.Items.Insert(0, "India");   
}

XAML

<ComboBox x:Name="combox" SelectionChanged="ComboBox_SelectionChanged_1"/>

I met these warnings on mempcpy function. Man page says this function is a GNU extension and synopsis shows:

#define _GNU_SOURCE
#include <string.h>

When #define is added to my source before the #include, declarations for the GNU extensions are made visible and warnings disappear.

I think that every JSON response should contain a property (e.g. {authenticated: false}) and the client has to test it everytime: if false, then the Angular controller/service will "redirect" to the login page.

And what happen if the user catch de JSON and change the bool to True?

I think you should never rely on client side to do these kind of stuff. If the user is not authenticated, the server should just redirect to a login/error page.

One other method that could be used depending on the need $('input').onfocus(function(){this.blur()}); I think this is how you would write it. I am not proficient in jquery.

To kill the puma process first run

    lsof -wni tcp:3000 

to show what is using port 3000. Then use the PID that comes with the result to run the kill process.

For example after running lsof -wni tcp:3000 you might get something like

    COMMAND  PID  USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
    ruby    3366 dummy    8u  IPv4  16901      0t0  TCP 127.0.0.1:3000 (LISTEN)

Now run the following to kill the process. (where 3366 is the PID)

kill -9 3366

Should resolve the issue

It seems you are hitting a UTF-8 byte order mark (BOM). Try using this unicode string with BOM extracted out:

import codecs

content = unicode(q.content.strip(codecs.BOM_UTF8), 'utf-8')
parser.parse(StringIO.StringIO(content))

I used strip instead of lstrip because in your case you had multiple occurences of BOM, possibly due to concatenated file contents.

The default colours in Gecko, assuming the user hasn't changed their preferences, are:

• standard link: #0000EE (blue)
• visited link: #551A8B (purple)
• active link: #EE0000 (red)

Source

Gecko also provides names for the user's colours; they are -moz-hyperlinktext -moz-visitedhyperlinktext and -moz-activehyperlinktext and they also provide -moz-nativehyperlinktext which is the system link colour.

You can use it in a more compact way as:

var tifs = {1: 'Joe', 2: 'Jane'};
...

return (
   <select id="tif" name="tif" onChange={this.handleChange}>  
      { Object.entries(tifs).map((t,k) => <option key={k} value={t[0]}>{t[1]}</option>) }          
   </select>
)

And another slightly different flavour:

 Object.entries(tifs).map(([key,value],i) => <option key={i} value={key}>{value}</option>)  

You can use the following in Firebase (FCM) to get the token:

FirebaseInstanceId.getInstance().getToken();

Use LinkedList instead. Than, you can create an array if necessary.

I just want to build upon Serpens answer and add the line:

logger.setLevel('DEBUG')

This will allow you to chose what level of message gets logged.

For example in Serpens example,

logger.info('Info message')

Will not get recorded as it defaults to only recording Warnings and above.

More about levels used can be read about here

This is what worked for me, since I wanted to have a separate index column

df = pd.DataFrame.from_dict(some_dict, orient="index").reset_index()
df.columns = ['A', 'B']

Since Mockito 2.0 there's also possibility to use static method Matchers.argThat(ArgumentMatcher). With the help of Java 8 it is now much cleaner and more readable to write:

verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("OneSurname")));
verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("AnotherSurname")));

If you're tied to lower Java version there's also not-that-bad:

verify(mockBar).doSth(argThat(new ArgumentMatcher<Employee>() {
        @Override
        public boolean matches(Object emp) {
            return ((Employee) emp).getSurname().equals("SomeSurname");
        }
    }));

Of course none of those can verify order of calls - for which you should use InOrder :

InOrder inOrder = inOrder(mockBar);

inOrder.verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("FirstSurname")));
inOrder.verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("SecondSurname")));

Please take a look at mockito-java8 project which makes possible to make calls such as:

verify(mockBar).doSth(assertArg(arg -> assertThat(arg.getSurname()).isEqualTo("Surname")));

I hope this could be helpful for whom has similar problem . In ObjectExplorer window, select your database=> Tables,=> your table=> Constraints. If the customer is defined on create column time, you can see the default name of constraint including the column name. then use:

ALTER TABLE  yourTableName DROP CONSTRAINT DF__YourTa__NewCo__47127295;

(the constraint name is just an example)

If you always search based on value3, you could store the objects in a Map:

Map<String, List<Sample>> map = new HashMap <>();

You can then populate the map with key = value3 and value = list of Sample objects with that same value3 property.

You can then query the map:

List<Sample> allSamplesWhereValue3IsDog = map.get("Dog");

Note: if no 2 Sample instances can have the same value3, you can simply use a Map<String, Sample>.

This far I've found this one is working, having to set a Timeout of 1ms for the action to complete after chrome's auto-filling ..

$(window).on('load', function() {
    setTimeout(function(){
        $('input[name*=email],input[name*=Password]').val('-').val(null);
    },1);
});

I'm wondering if there's any way of attaching this function to chrome self-completion firing, or even, redeclaring it

Anyone interested in doing this should read the documentation of the Django Sessions framework. It stores a session ID in the user's cookies, but maps all the cookies-like data to your database. This is an improvement on the typical cookies-based workflow for HTTP requests.

Here is an example with a Django view ...

def homepage(request):

    request.session.setdefault('how_many_visits', 0)
    request.session['how_many_visits'] += 1

    print(request.session['how_many_visits'])

    return render(request, 'home.html', {})

If you keep visiting the page over and over, you'll see the value start incrementing up from 1 until you clear your cookies, visit on a new browser, go incognito, or do anything else that sidesteps Django's Session ID cookie.

If you use checkbox

<input 
    type='checkbox'
    onChange={this.checkboxHandler}
/>

stopPropagation and stopImmediatePropagation won't be working.

Because you must using onClick={this.checkboxHandler}

If you are using SDK 28 or higher, you need to migrate to AndroidX library.

With Android Studio 3.2 and higher, you can migrate an existing project to AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.

What if you want your parts to contain commas? Well, quote them. And then what about the quotes? Well, double them up. In other words:

part1,"part2,with a comma and a quote "" in it",part3

PHP provides the https://php.net/str_getcsv function to parse a string as if it were a line in a CSV file which can be used with the above line instead of explode:

print_r(str_getcsv('part1,"part2,with a comma and a quote "" in it",part3'));
Array
(
    [0] => part1
    [1] => part2,with a comma and a quote " in it
    [2] => part3
)

Try this:

if [ ${STATUS} -ne 100 -a "${STRING}" = "${VALUE}" ]

or

if [ ${STATUS} -ne 100 ] && [ "${STRING}" = "${VALUE}" ]

If you add helper fields to the coordinates table, you can improve response time of the query.

Like this:

CREATE TABLE `Coordinates` (
`id` INT(10) UNSIGNED NOT NULL COMMENT 'id for the object',
`type` TINYINT(4) UNSIGNED NOT NULL DEFAULT '0' COMMENT 'type',
`sin_lat` FLOAT NOT NULL COMMENT 'sin(lat) in radians',
`cos_cos` FLOAT NOT NULL COMMENT 'cos(lat)*cos(lon) in radians',
`cos_sin` FLOAT NOT NULL COMMENT 'cos(lat)*sin(lon) in radians',
`lat` FLOAT NOT NULL COMMENT 'latitude in degrees',
`lon` FLOAT NOT NULL COMMENT 'longitude in degrees',
INDEX `lat_lon_idx` (`lat`, `lon`)
)    

If you're using TokuDB, you'll get even better performance if you add clustering indexes on either of the predicates, for example, like this:

alter table Coordinates add clustering index c_lat(lat);
alter table Coordinates add clustering index c_lon(lon);

You'll need the basic lat and lon in degrees as well as sin(lat) in radians, cos(lat)*cos(lon) in radians and cos(lat)*sin(lon) in radians for each point. Then you create a mysql function, smth like this:

CREATE FUNCTION `geodistance`(`sin_lat1` FLOAT,
                              `cos_cos1` FLOAT, `cos_sin1` FLOAT,
                              `sin_lat2` FLOAT,
                              `cos_cos2` FLOAT, `cos_sin2` FLOAT)
    RETURNS float
    LANGUAGE SQL
    DETERMINISTIC
    CONTAINS SQL
    SQL SECURITY INVOKER
   BEGIN
   RETURN acos(sin_lat1*sin_lat2 + cos_cos1*cos_cos2 + cos_sin1*cos_sin2);
   END

This gives you the distance.

Don't forget to add an index on lat/lon so the bounding boxing can help the search instead of slowing it down (the index is already added in the CREATE TABLE query above).

INDEX `lat_lon_idx` (`lat`, `lon`)

Given an old table with only lat/lon coordinates, you can set up a script to update it like this: (php using meekrodb)

$users = DB::query('SELECT id,lat,lon FROM Old_Coordinates');

foreach ($users as $user)
{
  $lat_rad = deg2rad($user['lat']);
  $lon_rad = deg2rad($user['lon']);

  DB::replace('Coordinates', array(
    'object_id' => $user['id'],
    'object_type' => 0,
    'sin_lat' => sin($lat_rad),
    'cos_cos' => cos($lat_rad)*cos($lon_rad),
    'cos_sin' => cos($lat_rad)*sin($lon_rad),
    'lat' => $user['lat'],
    'lon' => $user['lon']
  ));
}

Then you optimize the actual query to only do the distance calculation when really needed, for example by bounding the circle (well, oval) from inside and outside. For that, you'll need to precalculate several metrics for the query itself:

// assuming the search center coordinates are $lat and $lon in degrees
// and radius in km is given in $distance
$lat_rad = deg2rad($lat);
$lon_rad = deg2rad($lon);
$R = 6371; // earth's radius, km
$distance_rad = $distance/$R;
$distance_rad_plus = $distance_rad * 1.06; // ovality error for outer bounding box
$dist_deg_lat = rad2deg($distance_rad_plus); //outer bounding box
$dist_deg_lon = rad2deg($distance_rad_plus/cos(deg2rad($lat)));
$dist_deg_lat_small = rad2deg($distance_rad/sqrt(2)); //inner bounding box
$dist_deg_lon_small = rad2deg($distance_rad/cos(deg2rad($lat))/sqrt(2));

Given those preparations, the query goes something like this (php):

$neighbors = DB::query("SELECT id, type, lat, lon,
       geodistance(sin_lat,cos_cos,cos_sin,%d,%d,%d) as distance
       FROM Coordinates WHERE
       lat BETWEEN %d AND %d AND lon BETWEEN %d AND %d
       HAVING (lat BETWEEN %d AND %d AND lon BETWEEN %d AND %d) OR distance <= %d",
  // center radian values: sin_lat, cos_cos, cos_sin
       sin($lat_rad),cos($lat_rad)*cos($lon_rad),cos($lat_rad)*sin($lon_rad),
  // min_lat, max_lat, min_lon, max_lon for the outside box
       $lat-$dist_deg_lat,$lat+$dist_deg_lat,
       $lon-$dist_deg_lon,$lon+$dist_deg_lon,
  // min_lat, max_lat, min_lon, max_lon for the inside box
       $lat-$dist_deg_lat_small,$lat+$dist_deg_lat_small,
       $lon-$dist_deg_lon_small,$lon+$dist_deg_lon_small,
  // distance in radians
       $distance_rad);

EXPLAIN on the above query might say that it's not using index unless there's enough results to trigger such. The index will be used when there's enough data in the coordinates table. You can add FORCE INDEX (lat_lon_idx) to the SELECT to make it use the index with no regards to the table size, so you can verify with EXPLAIN that it is working correctly.

With the above code samples you should have a working and scalable implementation of object search by distance with minimal error.

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))

na.omit(dat)
  x1  x2
1  1 100
3  3 300
5  5 500

Constructor is part of ES6 also typescript is using es6 syntax and now days es7 as well so you can utilise advance feature which typescript would compile to es5/es4 (as per you define) to provide support to old browser.

While ngOnInIt is lifecycle hook of angular. It is initialised when your component is initialised. (Consider it's state as born of any new life)

It's wise to use ngOnInIt compare to constructor, because you have another lifecycle hook like ngOnDestory (Consider it as death of any life). Here you can unsubscribe to any observable which is good to prevent any memory leak.

Incase any question feel free to comment on this answer.

I had same problem when using VPN. Simple fixed with restarting internet connection.

Try this function....it works...

$(function() {
        var myOptions = {
            zoom: 10,
            center: latlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        var map = new google.maps.Map(document.getElementById("map_canvas"),myOptions);
        var latlng_pos=[];
        var j=0;
         $(".property_item").each(function(){
            latlng_pos[j]=new google.maps.LatLng($(this).find(".latitude").val(),$(this).find(".longitude").val());
            j++;
            var marker = new google.maps.Marker({
                position: new google.maps.LatLng($(this).find(".latitude").val(),$(this).find(".longitude").val()),
                // position: new google.maps.LatLng(-35.397, 150.640),
                map: map
            });
        }
        );
        // map: an instance of google.maps.Map object
        // latlng: an array of google.maps.LatLng objects
        var latlngbounds = new google.maps.LatLngBounds( );
        for ( var i = 0; i < latlng_pos.length; i++ ) {
            latlngbounds.extend( latlng_pos[ i ] );
        }
        map.fitBounds( latlngbounds );



    });

In my opinion every programmer has his or her own "words" that is used every time you need an arbitrary word when programming. For some people it's the first words from a childs song, for other it's names and for other its something completely different. Now for the programmer community there are these "words" as well, and these words are 'foo' and 'bar'. The use of this is that if you have to communicate publicly about programming you don't have to say that you would use arbitratry words, you would simply write 'foo' or 'bar' and every programmer knows that this is just arbitrary words.

I use

if(!my_set.count(that_element)) //Element is present...
;

But it is not as efficient as

if(my_set.find(that_element)!=my_set.end()) ....;

My version only saves my time in writing the code. I prefer it this way for competitive coding.

Use the correct doc type; it will solve the problem. Add the below line to the top of your HTML file:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

You can use many ports together for each project,

  php artisan serve --port=8000

  php artisan serve --port=8001   

  php artisan serve --port=8002

  php artisan serve --port=8003

inside shell:

mongod --version

Type the values in single cells, because google spreadsheet cant handle duration formats at all, in any way shape or form. Or you have to learn to make scripts and graduate as a chopper pilot. that is also a option.

To call a sub inside another sub you only need to do:

Call Subname()

So where you have CalculateA(Nc,kij, xi, a1, a) you need to have call CalculateA(Nc,kij, xi, a1, a)

As the which runs first problem it's for you to decide, when you want to run a sub you can go to the macro list select the one you want to run and run it, you can also give it a key shortcut, therefore you will only have to press those keys to run it. Although, on secondary subs, I usually do it as Private sub CalculateA(...) cause this way it does not appear in the macro list and it's easier to work

Hope it helps, Bruno

PS: If you have any other question just ask, but this isn't a community where you ask for code, you come here with a question or a code that isn't running and ask for help, not like you did "It would be great if you could write it in the Excel VBA format."

There are only two options:

• Find out by reading all rows (and then you might as well store them)

• run a specialized SELECT COUNT(*) query beforehand.

Going twice through the DataReader loop is really expensive, you would have to re-execute the query.

And (thanks to Pete OHanlon) the second option is only concurrency-safe when you use a transaction with a Snapshot isolation level.

Since you want to end up storing all rows in memory anyway the only sensible option is to read all rows in a flexible storage (List<> or DataTable) and then copy the data to any format you want. The in-memory operation will always be much more efficient.

The problem is that the function returns UTF-8 (it can check using mb_detect_encoding), but do not convert, and these characters takes as UTF-8. ?herefore, it's necessary to do the reverse-convert to initial encoding (Windows-1251 or CP1251) using iconv. But since by the fgetcsv returns an array, I suggest to write a custom function: [Sorry for my english]

function customfgetcsv(&$handle, $length, $separator = ';'){
    if (($buffer = fgets($handle, $length)) !== false) {
        return explode($separator, iconv("CP1251", "UTF-8", $buffer));
    }
    return false;
}

If you haven't committed changes

If your changes are compatible with the other branch

This is the case from the question because the OP wants to commit to a new branch and also applies if your changes are compatible with the target branch without triggering an overwrite.

As in the accepted answer by John Brodie, you can simply checkout the new branch and commit the work:

git checkout -b branch_name
git add <files>
git commit -m "message"

If your changes are incompatible with the other branch

If you get the error:

error: Your local changes to the following files would be overwritten by checkout:
...
Please commit your changes or stash them before you switch branches

Then you can stash your work, create a new branch, then pop your stash changes, and resolve the conflicts:

git stash
git checkout -b branch_name
git stash pop

It will be as if you had made those changes after creating the new branch. Then you can commit as usual:

git add <files>
git commit -m "message"

If you have committed changes

If you want to keep the commits in the original branch

See the answer by Carl Norum with cherry-picking, which is the right tool in this case:

git checkout <target name>
git cherry-pick <original branch>

If you don't want to keep the commits in the original branch

See the answer by joeytwiddle on this potential duplicate. Follow any of the above steps as appropriate, then roll back the original branch:

git branch -f <original branch> <earlier commit id>

If you have pushed your changes to a shared remote like GitHub, you should not attempt this roll-back unless you know what you are doing.

Windows path C:\src under cygwin becomes /cygdrive/c/src

If you already have the figure object use:

f.set_figheight(15)
f.set_figwidth(15)

But if you use the .subplots() command (as in the examples you're showing) to create a new figure you can also use:

f, axs = plt.subplots(2,2,figsize=(15,15))

Oracle's security model is such that when executing dynamic SQL using Execute Immediate (inside the context of a PL/SQL block or procedure), the user does not have privileges to objects or commands that are granted via role membership. Your user likely has "DBA" role or something similar. You must explicitly grant "drop table" permissions to this user. The same would apply if you were trying to select from tables in another schema (such as sys or system) - you would need to grant explicit SELECT privileges on that table to this user.

if you're using jQuery you would have:

$('#elementId').change(function() { alert('Do Stuff'); });

or MS AJAX:

$addHandler($get('elementId'), 'change', function(){ alert('Do Stuff'); });

Or in the raw HTML of the element:

<input type="text" onchange="alert('Do Stuff');" id="myElement" />

After re-reading the question I think I miss-read what was to be done. I've never found a way to update a DOM element in a manner which will force a change event, what you're best doing is having a separate event handler method, like this:

$addHandler($get('elementId'), 'change', elementChanged);
function elementChanged(){
  alert('Do Stuff!');
}
function editElement(){
  var el = $get('elementId');
  el.value = 'something new';
  elementChanged();
}

Since you're already writing a JavaScript method which will do the changing it's only 1 additional line to call.

Or, if you are using the Microsoft AJAX framework you can access all the event handlers via:

$get('elementId')._events

It'd allow you to do some reflection-style workings to find the right event handler(s) to fire.

in my case, datas is an objects of Array for more information please Click Here

<% for(let [index,data] of datas.entries() || []){  %>
 Index : <%=index%>
 Data : <%=data%>
<%} %>

The best way is this:

a = get_list()
return a[0] if a else None

You could also do it in one line, but it's much harder for the programmer to read:

return (get_list()[:1] or [None])[0]

This has nothing to do with the MULTILINE flag; what you're seeing is the difference between the find() and matches() methods. find() succeeds if a match can be found anywhere in the target string, while matches() expects the regex to match the entire string.

Pattern p = Pattern.compile("xyz");

Matcher m = p.matcher("123xyzabc");
System.out.println(m.find());    // true
System.out.println(m.matches()); // false

Matcher m = p.matcher("xyz");
System.out.println(m.matches()); // true

Furthermore, MULTILINE doesn't mean what you think it does. Many people seem to jump to the conclusion that you have to use that flag if your target string contains newlines--that is, if it contains multiple logical lines. I've seen several answers here on SO to that effect, but in fact, all that flag does is change the behavior of the anchors, ^ and $.

Normally ^ matches the very beginning of the target string, and $ matches the very end (or before a newline at the end, but we'll leave that aside for now). But if the string contains newlines, you can choose for ^ and $ to match at the start and end of any logical line, not just the start and end of the whole string, by setting the MULTILINE flag.

So forget about what MULTILINE means and just remember what it does: changes the behavior of the ^ and $ anchors. DOTALL mode was originally called "single-line" (and still is in some flavors, including Perl and .NET), and it has always caused similar confusion. We're fortunate that the Java devs went with the more descriptive name in that case, but there was no reasonable alternative for "multiline" mode.

In Perl, where all this madness started, they've admitted their mistake and gotten rid of both "multiline" and "single-line" modes in Perl 6 regexes. In another twenty years, maybe the rest of the world will have followed suit.

On Windows, start up Command Prompt (cmd.exe) or PowerShell (powershell.exe). To do this quickly, open a Run Command window by pressing Windows Key + R. In the Run Command window, type "cmd.exe" to launch Command Prompt; However, to start PowerShell instead, then type "powershell". If you are connecting your Android device to your computer using a USB cable, then you will need to check whether your device is communicating with adb by entering the command below:

# adb devices -l  

Next, pull (copy) the file from your Android device over to Windows. This can be accomplished by entering the following command:

# adb pull /sdcard/log.txt %HOME%\Desktop\log.txt  

Optionally, you may enter this command instead:

# adb pull /sdcard/log.txt C:\Users\admin\Desktop\log.txt 

pip is a package manager.

conda is both a package manager and an environment manager.

The approach I use is to start the "Visual Studio Command Prompt" which can be found in the Start menu. E.g. my visual studio 2010 Express install has a shortcute Visual Studio Command Prompt (2010) at Start Menu\Programs\Microsoft Visual Studio 2010\Visual Studio Tools.

This shortcut prepares an environment by calling a script vcvarsall.bat where the compiler, linker, etc. are setup from the right Visual Studio installation.

Alternatively, if you already have a prompt open, you can prepare the environment by calling a similar script:

:: For x86 (using the VS100COMNTOOLS env-var)
call "%VS100COMNTOOLS%"\..\..\VC\bin\vcvars32.bat

or

:: For amd64 (using the full path)
call C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\amd64\vcvars64.bat

However:

Your output (with the '$' prompt) suggests that you are attempting to run CMake from a MSys shell. In that case it might be better to run CMake for MSys or MinGW, by explicitly specifying a makefile generator:

cmake -G"MSYS Makefiles"
cmake -G"MinGW Makefiles"

Run cmake --help to get a list of all possible generators.

If you want to just compare dates,

yourdatetime.date() < datetime.today().date()

Or, obviously,

yourdatetime.date() == datetime.today().date()

If you want to check that they're the same date.

The documentation is usually helpful. It is also usually the first google result for python thing_i_have_a_question_about. Unless your question is about a function/module named "snake".

Basically, the datetime module has three types for storing a point in time:

• date for year, month, day of month
• time for hours, minutes, seconds, microseconds, time zone info
• datetime combines date and time. It has the methods date() and time() to get the corresponding date and time objects, and there's a handy combine function to combine date and time into a datetime.

I found the documentation of the various states of locking in SQLite to be very helpful. Michael, if you can perform reads but can't perform writes to the database, that means that a process has gotten a RESERVED lock on your database but hasn't executed the write yet. If you're using SQLite3, there's a new lock called PENDING where no more processes are allowed to connect but existing connections can sill perform reads, so if this is the issue you should look at that instead.

Other answers already explained that this isn't possible using the encoding/json package features directly.

Instead, I'd like to offer an alternative solution using a third-party library. Disclaimer: I am the author of the library.

https://github.com/wI2L/jettison

Jettison is a faster and flexible alternative to encoding/json, while still retaining a behavior identical to the standard library by default.

You can use the DenyList option to filter-out fields that should be omitted from the result. Note that the feature is limited, and only works for 1st-level fields.

I saw that two people put that question to their favorites so I will try to answer the solution which works for me: Instead of using find modules I'm writing configuration files for all libraries which are installed. Those files are extremly simple and can also be used to set non-standard variables. CMake will (at least on windows) search for those configuration files in

CMAKE_PREFIX_PATH/<<package_name>>-<<version>>/<<package_name>>-config.cmake

(which can be set through an environment variable). So for example the boost configuration is in the path

CMAKE_PREFIX_PATH/boost-1_50/boost-config.cmake

In that configuration you can set variables. My config file for boost looks like that:

set(boost_INCLUDE_DIRS ${boost_DIR}/include)
set(boost_LIBRARY_DIR ${boost_DIR}/lib)
foreach(component ${boost_FIND_COMPONENTS}) 
    set(boost_LIBRARIES ${boost_LIBRARIES} debug ${boost_LIBRARY_DIR}/libboost_${component}-vc110-mt-gd-1_50.lib)
    set(boost_LIBRARIES ${boost_LIBRARIES} optimized ${boost_LIBRARY_DIR}/libboost_${component}-vc110-mt-1_50.lib)
endforeach()
add_definitions( -D_WIN32_WINNT=0x0501 )

Pretty straight forward + it's possible to shrink the size of the config files even more when you write some helper functions. The only issue I have with this setup is that I havn't found a way to give config files a priority over find modules - so you need to remove the find modules.

Hope this this is helpful for other people.

Or in your SQL query wrap that field with IsNull or Coalesce (SQL Server).

Either way works, I like to put that logic in the query so the report has to do less.

Here's how I addressed this (using a MEAN derivative)

My variables:

{
  NODE_ENV : development,
  ...
  ui_varables {
     var1: one,
     var2: two
  }
}

First I had to make sure that the necessary config variables were being passed. MEAN uses the node nconf package, and by default is set up to limit which variables get passed from the environment. I had to remedy that:

config/config.js:

original:

nconf.argv()
  .env(['PORT', 'NODE_ENV', 'FORCE_DB_SYNC'] ) // Load only these environment variables
  .defaults({
  store: {
    NODE_ENV: 'development'
  }
});

after modifications:

nconf.argv()
  .env('__') // Load ALL environment variables
  // double-underscore replaces : as a way to denote hierarchy
  .defaults({
  store: {
    NODE_ENV: 'development'
  }
});

Now I can set my variables like this:

export ui_varables__var1=first-value
export ui_varables__var2=second-value

Note: I reset the "heirarchy indicator" to "__" (double underscore) because its default was ":", which makes variables more difficult to set from bash. See another post on this thread.

Now the jade part: Next the values need to be rendered, so that javascript can pick them up on the client side. A straightforward way to write these values to the index file. Because this is a one-page app (angular), this page is always loaded first. I think ideally this should be a javascript include file (just to keep things clean), but this is good for a demo.

app/controllers/index.js:

'use strict';
var config = require('../../config/config');

exports.render = function(req, res) {
  res.render('index', {
    user: req.user ? JSON.stringify(req.user) : "null",
    //new lines follow:
    config_defaults : {
       ui_defaults: JSON.stringify(config.configwriter_ui).replace(/<\//g, '<\\/')  //NOTE: the replace is xss prevention
    }
  });
};

app/views/index.jade:

extends layouts/default

block content
  section(ui-view)
    script(type="text/javascript").
    window.user = !{user};
    //new line here
    defaults = !{config_defaults.ui_defaults};

In my rendered html, this gives me a nice little script:

<script type="text/javascript">
 window.user = null;         
 defaults = {"var1":"first-value","var2:"second-value"};
</script>        

From this point it's easy for angular to utilize the code.

Some context additional about basic authentication, it consists in a header which contains the key/value pair:

Authorization: Basic Z2VybWFuOmdlcm1hbg==

where "Authorization" is the headers key, and the headers value has a string ( "Basic" word plus blank space) concatenated to "Z2VybWFuOmdlcm1hbg==", which are the user and password in base 64 joint by double dot

String name = "username";
String password = "secret";
String authString = name + ":" + password;
String authStringEnc = new BASE64Encoder().encode(authString.getBytes());
...
objectXXX.header("Authorization", "Basic " + authStringEnc);

byte[] a = new byte[50];

char [] cArray= System.Text.Encoding.ASCII.GetString(a).ToCharArray();

From the URL thedixon posted

http://bytes.com/topic/c-sharp/answers/250261-byte-char

You cannot ToCharArray the byte without converting it to a string first.

To quote Jon Skeet there

There's no need for the copying here - just use Encoding.GetChars. However, there's no guarantee that ASCII is going to be the appropriate encoding to use.

In case you have to download a file with a size larger than the allowed memory limit (memory_limit ini setting), which would cause the PHP Fatal error: Allowed memory size of 5242880 bytes exhausted error, you can do this:

// File to download.
$file = '/path/to/file';

// Maximum size of chunks (in bytes).
$maxRead = 1 * 1024 * 1024; // 1MB

// Give a nice name to your download.
$fileName = 'download_file.txt';

// Open a file in read mode.
$fh = fopen($file, 'r');

// These headers will force download on browser,
// and set the custom file name for the download, respectively.
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . $fileName . '"');

// Run this until we have read the whole file.
// feof (eof means "end of file") returns `true` when the handler
// has reached the end of file.
while (!feof($fh)) {
    // Read and output the next chunk.
    echo fread($fh, $maxRead);

    // Flush the output buffer to free memory.
    ob_flush();
}

// Exit to make sure not to output anything else.
exit;

In such case you will need to parse zip local header entries. Each file, stored in zip file, has preceding Local File Header entry, which (normally) contains enough information for decompression, Generally, you can make simple parsing of such entries in stream, select needed file, copy header + compressed file data to other file, and call unzip on that part (if you don't want to deal with the whole Zip decompression code or library).

How about this?

boolean uses_votes =
  ( "|1|yes|on|true|"
      .indexOf("|"+o.get("uses_votes").toLowerCase()+"|")
      > -1
  );

Use if foo or if not foo. There isn't any need for either == or is for that.

For checking against None, is None and is not None are recommended. This allows you to distinguish it from False (or things that evaluate to False, like "" and []).

Whether get_attr should return None would depend on the context. You might have an attribute where the value is None, and you wouldn't be able to do that. I would interpret None as meaning "unset", and a KeyError would mean the key does not exist in the file.

You can do this without additional tools in VBScript:

Do Until WScript.StdIn.AtEndOfStream
  WScript.StdOut.WriteLine WScript.StdIn.ReadLine
Loop

Put the above lines in a file unix2dos.vbs and run it like this:

cscript //NoLogo unix2dos.vbs <C:\path\to\input.txt >C:\path\to\output.txt

or like this:

type C:\path\to\input.txt | cscript //NoLogo unix2dos.vbs >C:\path\to\output.txt

You can also do it in PowerShell:

(Get-Content "C:\path\to\input.txt") -replace "`n", "`r`n" |
  Set-Content "C:\path\to\output.txt"

which could be further simplified to this:

(Get-Content "C:\path\to\input.txt") | Set-Content "C:\path\to\output.txt"

The above statement works without an explicit replacement, because Get-Content implicitly splits input files at any kind of linebreak (CR, LF, and CR-LF), and Set-Content joins the input array with Windows linebreaks (CR-LF) before writing it to a file.

To change password using Linux command line, use:

Just want to give one example why we decided to store image in DB not files or CDN, it is storing images of signatures.

We have tried to do so via CDN, cloud storage, files, and finally decided to store in DB and happy about the decision as it was proven us right in our subsequent events when we moved, upgraded our scripts and migrated the sites serveral times.

For my case, we wanted the signatures to be with the records that belong to the author of documents.

Storing in files format risks missing them or deleted by accident.

We store it as a blob binary format in MySQL, and later as based64 encoded image in a text field. The decision to change to based64 was due to smaller size as result for some reason, and faster loading. Blob was slowing down the page load for some reason.

In our case, this solution to store signature images in DB, (whether as blob or based64), was driven by:

1. Most signature images are very small.
2. We don't need to index the signature images stored in DB.
3. Index is done on the primary key.
4. We may have to move or switch servers, moving physical images files to different servers, may cause the images not found due to links change.
5. it is embarrassed to ask the author to re-sign their signatures.
6. it is more secured saving in the DB as compared to exposing it as files which can be downloaded if security is compromised. Storing in DB allows us better control over its access.
7. any future migrations, change of web design, hosting, servers, we have zero worries about reconcilating the signature file names against the physical files, it is all in the DB!

    defer { UIGraphicsEndImageContext() }

Set the tagName as an explicit attribute:

for(var i=0,els=document.querySelectorAll('*'); i<els.length;
          els[i].setAttribute('tagName',els[i++].tagName) );

I needed this myself, for an XML Document, with Nested Tags ending in _Sequence. See JaredMcAteer answer for more details.

document.querySelectorAll('[tagName$="_Sequence"]')

I didn't say it would be pretty :) PS: I would recommend to use tag_name over tagName, so you do not run into interferences when reading 'computer generated', implicit DOM attributes.

to join a windows path, try

mypath=os.path.join('c:\\', 'sourcedir')

basically, you will need to escape the slash

Try to not use the -W parameter and leave the password in blank. Sometimes the user is created with no-password.

If that doesn't work reset the password. There are several ways to do it, but this works on many systems:

$ su root
$ su postgres
$ psql -h localhost
> ALTER USER postgres with password 'YourNewPassword';

What is the double pipe operator (||)?

The double pipe operator (||) is the logical OR operator . In most languages it works the following way:

• If the first value is false, it checks the second value. If that's true, it returns true and if the second value is false, it returns false.
• If the first value is true, it always returns true, no matter what the second value is.

So basically it works like this function:

function or(x, y) {
  if (x) {
    return true;
  } else if (y) {
    return true;
  } else {
    return false;
  }
}

If you still don't understand, look at this table:

      | true   false  
------+---------------
true  | true   true   
false | true   false  

In other words, it's only false when both values are false.

How is it different in JavaScript?

JavaScript is a bit different, because it's a loosely typed language. In this case it means that you can use || operator with values that are not booleans. Though it makes no sense, you can use this operator with for example a function and an object:

(function(){}) || {}

What happens there?

If values are not boolean, JavaScript makes implicit conversion to boolean. It means that if the value is falsey (e.g. 0, "", null, undefined (see also All falsey values in JavaScript)), it will be treated as false; otherwise it's treated as true.

So the above example should give true, because empty function is truthy. Well, it doesn't. It returns the empty function. That's because JavaScript's || operator doesn't work as I wrote at the beginning. It works the following way:

• If the first value is falsey, it returns the second value.
• If the first value is truthy, it returns the first value.

Surprised? Actually, it's "compatible" with the traditional || operator. It could be written as following function:

function or(x, y) {
  if (x) {
    return x;
  } else {
    return y;
  }
}

If you pass a truthy value as x, it returns x, that is, a truthy value. So if you use it later in if clause:

(function(x, y) {
  var eitherXorY = x || y;
  if (eitherXorY) {
    console.log("Either x or y is truthy.");
  } else {
    console.log("Neither x nor y is truthy");
  }
}(true/*, undefined*/));

you get "Either x or y is truthy.".

If x was falsey, eitherXorY would be y. In this case you would get the "Either x or y is truthy." if y was truthy; otherwise you'd get "Neither x nor y is truthy".

The actual question

Now, when you know how || operator works, you can probably make out by yourself what does x = x || y mean. If x is truthy, x is assigned to x, so actually nothing happens; otherwise y is assigned to x. It is commonly used to define default parameters in functions. However, it is often considered a bad programming practice, because it prevents you from passing a falsey value (which is not necessarily undefined or null) as a parameter. Consider following example:

function badFunction(/* boolean */flagA) {
  flagA = flagA || true;
  console.log("flagA is set to " + (flagA ? "true" : "false"));
}

It looks valid at the first sight. However, what would happen if you passed false as flagA parameter (since it's boolean, i.e. can be true or false)? It would become true. In this example, there is no way to set flagA to false.

It would be a better idea to explicitly check whether flagA is undefined, like that:

function goodFunction(/* boolean */flagA) {
  flagA = typeof flagA !== "undefined" ? flagA : true;
  console.log("flagA is set to " + (flagA ? "true" : "false"));
}

Though it's longer, it always works and it's easier to understand.

You can also use the ES6 syntax for default function parameters, but note that it doesn't work in older browsers (like IE). If you want to support these browsers, you should transpile your code with Babel.

The error is misleading - it says "pubkey" while pointing to a private key file ~/.ssh/id_rsa.

In my case, it was simply a missing public key (as I haven't restored it from a vault).

DETAILS

I used to skip deploying ~/.ssh/id_rsa.pub by automated scripts.

All ssh usages worked, but the error made me think of a possible mess.

Not at all - strace helped to notice that the trigger was actually the *.pub file:

strace ssh example.com
...
openat(AT_FDCWD, "/home/uvsmtid/.ssh/id_rsa.pub", O_RDONLY) = -1 ENOENT (No such file or directory)
...
write(2, "load pubkey \"/home/uvsmtid/.ssh/"..., 57) = 57
load pubkey "/home/uvsmtid/.ssh/id_rsa": invalid format

This should work for you :) Yes var should be used

Object doesn't support this property or method.

Think of it like if anything after the dot is called on an object. It's like a chain.

An object is a class instance. A class instance supports some properties defined in that class type definition. It exposes whatever intelli-sense in VBE tells you (there are some hidden members but it's not related to this). So after each dot . you get intelli-sense (that white dropdown) trying to help you pick the correct action.

(you can start either way - front to back or back to front, once you understand how this works you'll be able to identify where the problem occurs)

Type this much anywhere in your code area

Dim a As Worksheets
a.

you get help from VBE, it's a little dropdown called Intelli-sense

It lists all available actions that particular object exposes to any user. You can't see the .Selection member of the Worksheets() class. That's what the error tells you exactly.

Object doesn't support this property or method.

If you look at the example on MSDN

Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count

It activates the sheet first then calls the Selection... it's not connected together because Selection is not a member of Worksheets() class. Simply, you can't prefix the Selection

What about

Sub DisplayColumnCount()
    Dim iAreaCount As Integer
    Dim i As Integer

    Worksheets("GRA").Activate
    iAreaCount = Selection.Areas.Count

    If iAreaCount <= 1 Then
        MsgBox "The selection contains " & Selection.Columns.Count & " columns."
    Else
        For i = 1 To iAreaCount
        MsgBox "Area " & i & " of the selection contains " & _
        Selection.Areas(i).Columns.Count & " columns."
        Next i
    End If
End Sub

why not simply use php's urlencode? it replaces "dangerous" characters with their hex representation for urls (i.e. %20 for a space)

The code from Alex works great. Just note that when you use request.getParameter you must use a request dispatcher

//Pass results back to the client
RequestDispatcher dispatcher =   getServletContext().getRequestDispatcher("TestPages/ServiceServlet.jsp");
dispatcher.forward(request, response);

If you want more control over how the conversion takes place, you can use ConvertAll:

var stringList = myList.ConvertAll(obj => obj.SomeToStringMethod());

Lets take an anchor tag with an onclick event, that calls a Javascript function.

<a href="#" onClick="showDiv(1);">1</a>

Now in javascript write the below code

function showDiv(pageid)
{
   alert(pageid);
}

This will show you an alert of "1"....

Rather give names of the column on which you want to merge:

exporttab <- merge(x=dwd_nogap, y=dwd_gap, by.x='x1', by.y='x2', fill=-9999)

If you want to get Syntax Error with line number, use this

error: function(xhr, status, error) {
  alert(error);
}

After reading the w3.org spec. I found the sandbox property.

You can set sandbox="", which prevents the iframe from redirecting. That being said it won't redirect the iframe either. You will lose the click essentially.

Use the GeoCoding API

For example, to lookup zip 77379 use a request like this:

https://maps.googleapis.com/maps/api/geocode/json?address=77379&sensor=true&key=YOUR_GOOGLE_PLATFORM_API_KEY

Try replaceAll() method of the String class.

BTW here is the method, return type and parameters.

public String replaceAll(String regex,
                         String replacement)

Example:

String str = "Hello +-^ my + - friends ^ ^^-- ^^^ +!";
str = str.replaceAll("[-+^]*", "");

It should remove all the {'^', '+', '-'} chars that you wanted to remove!

You can pass an object which is refering to all the values at a particular index.

import java.util.ArrayList;

public class HelloWorld{

 public static void main(String []args){


ArrayList<connect> a=new ArrayList<connect>();

a.add(new connect(100,100,100,100,100));

System.out.println(a.get(0).p1);

System.out.println(a.get(0).p2);

System.out.println(a.get(0).p3);
}

}

class connect
{
int p1,p2,p3,p4,p5;

connect(int a,int b,int c,int d,int e)
{

this.p1=a;

this.p2=b;

this.p3=c;

this.p4=d;

this.p5=e;
}

}

Later to get a particular value at a specific index, you can do this:

a.get(0).p1;

a.get(0).p2;

a.get(0).p3;.............

and so on.

You can do something like this to automatically register them all into a collection with which to then easily convert the integers to the corresponding enum. (BTW, adding them to the map in the enum constructor is not allowed. It's nice to learn new things even after many years of using Java. :)

public enum PcapLinkType {
    DLT_NULL(0),
    DLT_EN10MB(1),
    DLT_EN3MB(2),
    DLT_AX25(3),
    /*snip, 200 more enums, not always consecutive.*/
    DLT_UNKNOWN(-1);

    private static final Map<Integer, PcapLinkType> typesByValue = new HashMap<Integer, PcapLinkType>();

    static {
        for (PcapLinkType type : PcapLinkType.values()) {
            typesByValue.put(type.value, type);
        }
    }

    private final int value;

    private PcapLinkType(int value) {
        this.value = value;
    }

    public static PcapLinkType forValue(int value) {
        return typesByValue.get(value);
    }
}

Using MySQL inbuilt function group_concat() will be a good choice for getting the desired result. The syntax will be -

SELECT group_concat(STRINGVALUE) 
FROM Jira.customfieldvalue
WHERE CUSTOMFIELD = 12534
AND ISSUE = 19602

Before you execute the above command make sure you increase the size of group_concat_max_len else the the whole output may not fit in that cell.

To set the value of group_concat_max_len, execute the below command-

SET group_concat_max_len = 50000;

You can change the value 50000 accordingly, you increase it to a higher value as required.

The latest version was not available as a binary for mac on git-scm.com, so I installed from source. I was missing a required package for localization, and added NO_GETTEXT=true to install without localization.

git clone https://github.com/git/git.git
cd git
make NO_GETTEXT=true
make NO_GETTEXT=true install

This installed git under ~/bin which I then had to add to the beginning of my PATH variable.
