If you have code in your Page_Load() event. Try adding this:

if (!Page.IsPostBack)
{ 
//your code here 
}

Check out JGraphT for a very simple and powerful Java graph library that is pretty well done and, to allay any confusion, is different than JGraph. Some sample code:

UndirectedGraph<String, DefaultEdge> g =
        new SimpleGraph<String, DefaultEdge>(DefaultEdge.class);

    String v1 = "v1";
    String v2 = "v2";
    String v3 = "v3";
    String v4 = "v4";

    // add the vertices
    g.addVertex(v1);
    g.addVertex(v2);
    g.addVertex(v3);
    g.addVertex(v4);

    // add edges to create a circuit
    g.addEdge(v1, v2);
    g.addEdge(v2, v3);
    g.addEdge(v3, v4);
    g.addEdge(v4, v1);

According to http://php.net/manual/en/function.error-get-last.php, use:

print_r(error_get_last());

Which will return an array of the last error generated. You can access the [message] element to display the error.

and here's one with Python

randport=$(python -S -c "import random; print random.randrange(2000,63000)")

and one with awk

awk 'BEGIN{srand();print int(rand()*(63000-2000))+2000 }'

Non-matched part of the URL is exposed as a request attribute named HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE:

@RequestMapping("/{id}/**")
public void foo(@PathVariable("id") int id, HttpServletRequest request) {
    String restOfTheUrl = (String) request.getAttribute(
        HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
    ...
}

First, &:name is a shortcut for &:name.to_proc, where :name.to_proc returns a Proc (something that is similar, but not identical to a lambda) that when called with an object as (first) argument, calls the name method on that object.

Second, while & in def foo(&block) ... end converts a block passed to foo to a Proc, it does the opposite when applied to a Proc.

Thus, &:name.to_proc is a block that takes an object as argument and calls the name method on it, i. e. { |o| o.name }.

I've had better results by checking the browsers readystate before continuing to the next step. This will do nothing until the browser is has a "complete" readystate

Do While WebBrowser1.ReadyState <> 4
''' put anything here. 
Loop

Here is the simplest thing I've found

-- Midnight floor of current date

SELECT Convert(DateTime, DATEDIFF(DAY, 0, GETDATE()))

The DATEDIFF returns the integer number of days before or since 1900-1-1, and the Convert Datetime obligingly brings it back to that date at midnight.

Since DateDiff returns an integer you can use add or subtract days to get the right offset.

SELECT Convert(DateTime, DATEDIFF(DAY, 0, GETDATE()) + @dayOffset)

This isn't rounding this is truncating...But I think that is what is being asked. (To round add one and truncate...and that's not rounding either, that the ceiling, but again most likely what you want. To really round add .5 (does that work?) and truncate.

It turns out you can add .5 to GetDate() and it works as expected.

-- Round Current time to midnight today or midnight tomorrow

SELECT Convert(DateTime, DATEDIFF(DAY, 0, GETDATE() + .5))

I did all my trials on SQL Server 2008, but I think these functions apply to 2005 as well.

EDIT Since not so recently by now, MinGW-w64 has "absorbed" one of the toolchain building projects. The downloads can be found here. The installer should work, and allow you to pick a version that you need.

Note the Qt SDK comes with the same toolchain. So if you are developing in Qt and using the SDK, just use the toolchain it comes with.

Another alternative that has up to date toolchains comes from... harhar... a Microsoft developer, none other than STL (Stephan T. Lavavej, isn't that a spot-on name for the maintainer of MSVC++ Standard Library!). You can find it here. It includes Boost.

Another option which is highly useful if you care for prebuilt dependencies is MSYS2, which provides a Unix shell (a Cygwin fork modified to work better with Windows pathnames and such), also provides a GCC. It usually lags a bit behind, but that is compensated for by its good package management system and stability. They also provide a functional Clang with libc++ if you care for such thing.

I leave the below for reference, but I strongly suggest against using MinGW.org, due to limitations detailed below. TDM-GCC (the MinGW-w64 version) provides some hacks that you may find useful in your specific situation, although I recommend using vanilla GCC at all times for maximum compatibility.

GCC for Windows is provided by two projects currently. They both provide a very own implementation of the Windows SDK (headers and libraries) which is necessary because GCC does not work with Visual Studio files.

1. The older mingw.org, which @Mat already pointed you to. They provide only a 32-bit compiler. See here for the downloads you need:

   • Binutils is the linker and resource compiler etc.
   • GCC is the compiler, and is split in core and language packages
   • GDB is the debugger.
   • runtime library is required only for mingw.org
   • You might need to download mingw32-make seperately.
   • For support, you can try (don't expect friendly replies) [email protected]

   Alternatively, download mingw-get and use that.

2. The newer mingw-w64, which as the name predicts, also provides a 64-bit variant, and in the future hopefully some ARM support. I use it and built toolchains with their CRT. Personal and auto builds are found under "Toolchains targetting Win32/64" here. They also provide Linux to Windows cross-compilers. I suggest you try a personal build first, they are more complete. Try mine (rubenvb) for GCC 4.6 to 4.8, or use sezero's for GCC 4.4 and 4.5. Both of us provide 32-bit and 64-bit native toolchains. These packages include everything listed above. I currently recommend the "MinGW-Builds" builds, as these are currently sanctioned as "official builds", and come with an installer (see above).

   For support, send an email to [email protected] or post on the forum via sourceforge.net.

Both projects have their files listed on sourceforge, and all you have to do is either run the installer (in case of mingw.org) or download a suitable zipped package and extract it (in the case of mingw-w64).

There are a lot of "non-official" toolchain builders, one of the most popular is TDM-GCC. They may use patches that break binary compatibility with official/unpatched toolchains, so be careful using them. It's best to use the official releases.

Very close! In your select expression, you have to use a pipe (|) before contains.

This filter produces the expected output.

. - map(select(.Names[] | contains ("data"))) | .[] .Id

The jq Cookbook has an example of the syntax.

Filter objects based on the contents of a key

E.g., I only want objects whose genre key contains "house".

$ json='[{"genre":"deep house"}, {"genre": "progressive house"}, {"genre": "dubstep"}]'
$ echo "$json" | jq -c '.[] | select(.genre | contains("house"))'
{"genre":"deep house"}
{"genre":"progressive house"}

Colin D asks how to preserve the JSON structure of the array, so that the final output is a single JSON array rather than a stream of JSON objects.

The simplest way is to wrap the whole expression in an array constructor:

$ echo "$json" | jq -c '[ .[] | select( .genre | contains("house")) ]'
[{"genre":"deep house"},{"genre":"progressive house"}]

You can also use the map function:

$ echo "$json" | jq -c 'map(select(.genre | contains("house")))'
[{"genre":"deep house"},{"genre":"progressive house"}]

map unpacks the input array, applies the filter to every element, and creates a new array. In other words, map(f) is equivalent to [.[]|f].

I had the same problem, caused by the Debian/ Ubuntu default configuration of module suphp. It contained suPHP_Engine off for whole /usr/share, which resulted in the php sources being shown in the browser. Deactivating with a2dismod suphp was the interim solution.

Edit: I just found out while debugging that the class is instantiated before every test too. I guess the @BeforeClass annotation is the best here.

You can set up on the constructor too, the test class is a class after all. I'm not sure if it's a bad practice because almost all other methods are annotated, but it works. You could create a constructor like that:

public UT () {
    // initialize once here
}
@Test
// Some test here...

The ctor will be called before the tests because they are not static.

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

I have implemented this way and it works.It is much easier than all that is reported.

We have two activities : one is the main and another is the secondary.

In secondary activity, which is where we want to end the main activity , define the following variable:

public static Activity ACTIVIDAD;

And then the following method:

public static void enlaceActividadPrincipal(Activity actividad) 
{
    tuActividad.ACTIVIDAD=actividad;
}

Then, in your main activity from the onCreate method , you make the call:

    actividadSecundaria.enlaceActividadPrincipal(this);

Now, you're in control. Now, from your secondary activity, you can complete the main activity. Finish calling the function, like this:

ACTIVIDAD.finish();

It is not possible to directly make a 3d surface using your data. I would recommend you to build an interpolation model using some tools like pykridge. The process will include three steps:

1. Train an interpolation model using pykridge
2. Build a grid from X and Y using meshgrid
3. Interpolate values for Z

Having created your grid and the corresponding Z values, now you're ready to go with plot_surface. Note that depending on the size of your data, the meshgrid function can run for a while. The workaround is to create evenly spaced samples using np.linspace for X and Y axes, then apply interpolation to infer the necessary Z values. If so, the interpolated values might different from the original Z because X and Y have changed.

You say that if int(splitLine[0]) > int(lastUnix): is causing the trouble, but you don't actually show anything which suggests that. I think this line is the problem instead:

print 'Pulled', + stock

Do you see why this line could cause that error message? You want either

>>> stock = "AAAA"
>>> print 'Pulled', stock
Pulled AAAA

or

>>> print 'Pulled ' + stock
Pulled AAAA

not

>>> print 'Pulled', + stock
PulledTraceback (most recent call last):
  File "<ipython-input-5-7c26bb268609>", line 1, in <module>
    print 'Pulled', + stock
TypeError: bad operand type for unary +: 'str'

You're asking Python to apply the + symbol to a string like +23 makes a positive 23, and she's objecting.

Either way gets the job done. I assume that by zigzag you mean something like this: (numbers are order of rendering)

..  ..  01  ..  ..
  ..  06  02  ..
..  11  07  03  ..
  16  12  08  04
21  17  13  09  05
  22  18  14  10
..  23  19  15  ..
  ..  24  20  ..
..  ..  25  ..  ..

And by diamond you mean:

..  ..  ..  ..  ..
  01  02  03  04
..  05  06  07  ..
  08  09  10  11
..  12  13  14  ..
  15  16  17  18
..  19  20  21  ..
  22  23  24  25
..  ..  ..  ..  ..

The first method needs more tiles rendered so that the full screen is drawn, but you can easily make a boundary check and skip any tiles fully off-screen. Both methods will require some number crunching to find out what is the location of tile 01. In the end, both methods are roughly equal in terms of math required for a certain level of efficiency.

Oracle does not have a simple database model like MySQL or MS SQL Server. I find the closest thing is to query the tablespaces and the corresponding users within them.

For example, I have a DEV_DB tablespace with all my actual 'databases' within them:

SQL> SELECT TABLESPACE_NAME FROM USER_TABLESPACES;

Resulting in:

SYSTEM
SYSAUX
UNDOTBS1
TEMP
USERS
EXAMPLE
DEV_DB

It is also possible to query the users in all tablespaces:

SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS;

Or within a specific tablespace (using my DEV_DB tablespace as an example):

SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS where DEFAULT_TABLESPACE = 'DEV_DB';

ROLES DEV_DB
DATAWARE DEV_DB
DATAMART DEV_DB
STAGING DEV_DB

Datatables only can order by DateTime in "ISO-8601" format, so you have to convert your date in "date-order" to this format (example using Razor):

<td data-sort="@myDate.ToString("o")">@myDate.ToShortDateString() - @myDate.ToShortTimeString()</td>

-O is the option to specify the path of the file you want to download to:

wget <uri> -O /path/to/file.ext

-P is prefix where it will download the file in the directory:

wget <uri> -P /path/to/folder

If you don't want Jquery (and can use ES6)

for (const option of document.getElementById('mySelect')) {
  console.log(option);
}

Update for Swift 4.2

var attributes = [NSAttributedString.Key: AnyObject]()

attributes[.foregroundColor] = UIColor.blue

let attributedString = NSAttributedString(string: "Very Bad",
attributes: attributes)

label.attributedText = attributedString

This will get you all the user created tables:

select * from sysobjects where xtype='U'

To get the cols:

Select * from Information_Schema.Columns Where Table_Name = 'Insert Table Name Here'

Also, I find http://www.sqlservercentral.com/ to be a pretty good db resource.

I found this to be the easiest way to change it server side.

Looks like something is messed up with your MySQL installation. The mysql.user table should definitely exist. Try running the command below on your server to create the tables in the database called mysql:

mysql_install_db

If that doesn't work, maybe the permissions on your MySQL data directory are messed up. Look at a "known good" installation as a reference for what the permissions should be.

You could also try re-installing MySQL completely.

Look into git-reflog. It will list all the states it remembers (default is 30 days), and you can simply checkout the one you want. For example:

$ git init > /dev/null
$ touch a
$ git add .
$ git commit -m"Add file a" > /dev/null
$ echo 'foo' >> a
$ git commit -a -m"Append foo to a" > /dev/null
$ for i in b c d e; do echo $i >>a; git commit -a -m"Append $i to a" ;done > /dev/null
$ git reset --hard HEAD^^ > /dev/null
$ cat a
foo
b
c
$ git reflog
145c322 HEAD@{0}: HEAD^^: updating HEAD
ae7c2b3 HEAD@{1}: commit: Append e to a
fdf2c5e HEAD@{2}: commit: Append d to a
145c322 HEAD@{3}: commit: Append c to a
363e22a HEAD@{4}: commit: Append b to a
fa26c43 HEAD@{5}: commit: Append foo to a
0a392a5 HEAD@{6}: commit (initial): Add file a
$ git reset --hard HEAD@{2}
HEAD is now at fdf2c5e Append d to a
$ cat a
foo

Since I have to store various types of content in my blob field/column, I am suppose to update my code like this:

echo "data: $mime" $result['$data']";

where: mime can be an image of any kind, text, word document, text document, PDF document, etc... content datatype is blob in database.

You can create $i outside the loop and do $i++ at the bottom of the loop.

If you care target files to be symbolic link, firstly you can check it and get the original file. The if clause below may help you.

if [ -h $file ]
then
 base=$(dirname $(readlink $file))
else
 base=$(dirname $file)

This is how I fixed this issue on Windows 10:

My JDK is located in C:\Program Files\Java\jdk-11.0.2 and the problem I had was the space in Program Files. If I set JAVA_HOME using set JAVA_HOME="C:\Program Files\Java\jdk-11.0.2" then Maven had an issue with the double quotes:

C:\Users>set JAVA_HOME="C:\Program Files\Java\jdk-11.0.2"

C:\Users>echo %JAVA_HOME%
"C:\Program Files\Java\jdk-11.0.2"

C:\Users>mvn -version

Referring to Program Files as PROGRA~1 didn't help either. The solution is using the PROGRAMFILES variable inside of JAVA_HOME:

You can simply use

$str = '<textformat leading="2"><p align="left"><font size="10">get me</font></p></textformat>';
echo strip_tags($str);

https://www.php.net/manual/en/function.strip-tags.php

/** eworkyou **//

$('#navigation a').bind('click',function(e){

    var $this   = $(this);
    var prev    = current;

    if (current == 1){
    $("#navigation a:eq(1)").unbind("click"); // 
    }
    if (current >= 2){
    $("#navigation a:eq(1)").bind("click"); // 
    }

It is possible only in the case when the factor labels match the original values. I will explain it with an example.

Assume the data is vector x:

x <- c(20, 10, 30, 20, 10, 40, 10, 40)

Now I will create a factor with four labels:

f <- factor(x, levels = c(10, 20, 30, 40), labels = c("A", "B", "C", "D"))

1) x is with type double, f is with type integer. This is the first unavoidable loss of information. Factors are always stored as integers.

> typeof(x)
[1] "double"
> typeof(f)
[1] "integer"

2) It is not possible to revert back to the original values (10, 20, 30, 40) having only f available. We can see that f holds only integer values 1, 2, 3, 4 and two attributes - the list of labels ("A", "B", "C", "D") and the class attribute "factor". Nothing more.

> str(f)
 Factor w/ 4 levels "A","B","C","D": 2 1 3 2 1 4 1 4
> attributes(f)
$levels
[1] "A" "B" "C" "D"

$class
[1] "factor"

To revert back to the original values we have to know the values of levels used in creating the factor. In this case c(10, 20, 30, 40). If we know the original levels (in correct order), we can revert back to the original values.

> orig_levels <- c(10, 20, 30, 40)
> x1 <- orig_levels[f]
> all.equal(x, x1)
[1] TRUE

And this will work only in case when labels have been defined for all possible values in the original data.

So if you will need the original values, you have to keep them. Otherwise there is a high chance it will not be possible to get back to them only from a factor.

There is also EntityFunctions.TruncateTime or DbFunctions.TruncateTime in EF 6.0

With modern SVN you can just run svn auth to display the list of cached credentials.

You have a JSON string, not an object. Tell jQuery that you expect a JSON response and it will parse it for you. Either use $.getJSON instead of $.get, or pass the dataType argument to $.get:

$.get(
    'index.php?r=admin/post/ajax',
    {"parentCatId":parentCatId},
    function(data){                     
        $.each(data, function(key, value){
            console.log(key + ":" + value)
        })
    },
    'json'
);

I think this is the easiest answer.

Use a "Name" to reference the offset.

Say you want to sum a column (Column A) all the way to, but not including, the cell holding the summation (say Cell A100); do this:

(I assume you are using A1 referencing when creating the Name; R1C1 can subsequently be switched to)

1. Click anywhere in the sheet not on the top row - say Cell D9
2. Define a Named Range called, say "OneCellAbove", but overwrite the 'RefersTo' box with "=D8" (no quotes)
3. Now, in Cell A100 you can use the formula

   =SUM(A1:OneCellAbove)

Arrays in JS have two types of properties:

Regular elements and associative properties (which are nothing but objects)

When you define a = new Array(), you are defining an empty array. Note that there are no associative objects yet

When you define b = new Array(2), you are defining an array with two undefined locations.

In both your examples of 'a' and 'b', you are adding associative properties i.e. objects to these arrays.

console.log (a) or console.log(b) prints the array elements i.e. [] and [undefined, undefined] respectively. But since a1/a2 and b1/b2 are associative objects inside their arrays, they can be logged only by console.log(a.a1, a.a2) kind of syntax

You can achieve what you want with the mysql console with the -s (--silent) option passed in.

It's probably a good idea to also pass in the -r (--raw) option so that special characters don't get escaped. You can use this to pipe queries like you're wanting.

mysql -u username -h hostname -p -s -r -e "select concat('this',' ','works')"

EDIT: Also, if you want to remove the column name from your output, just add another -s (mysql -ss -r etc.)

You could use Levenshtein distance to calculate the difference between two strings. http://en.wikipedia.org/wiki/Levenshtein_distance

if you need the full URL as everything from the http to the querystring you will need to concatenate the following variables

Request.ServerVariables("HTTPS") // to check if it's HTTP or HTTPS
Request.ServerVariables("SERVER_NAME") 
Request.ServerVariables("SCRIPT_NAME") 
Request.ServerVariables("QUERY_STRING")

The iterator_facade documentation from Boost.Iterator provides what looks like a nice tutorial on implementing iterators for a linked list. Could you use that as a starting point for building a random-access iterator over your container?

If nothing else, you can take a look at the member functions and typedefs provided by iterator_facade and use it as a starting point for building your own.

The best way I found is count by converting it to a list.

IEnumerable<T> enumList = ReturnFromSomeFunction();

int count = new List<T>(enumList).Count;

There's two parts to this question, really.

1. Q: Which browsers support the "async" attribute on a script tag in markup?

   A: IE10p2+, Chrome 11+, Safari 5+, Firefox 3.6+

2. Q: Which browsers support the new spec that defines behavior for the "async" property in JavaScript, on a dynamically created script element?

   A: IE10p2+, Chrome 12+, Safari 5.1+, Firefox 4+

As for Opera, they are very close to releasing a version which will support both types of async. I've been working with them closely on this, and it should come out soon (I hope!).

More info on ordered-async (aka, "async=false") can be found here: http://wiki.whatwg.org/wiki/Dynamic_Script_Execution_Order

Also, to test if a browser supports the new dynamic async property behavior: http://test.getify.com/test-async/

Spring Framework provides an excellent utils class for achieving this.

For anyone who needs to run a program in the background "without PHP waiting for it to finish" do this:

 pclose(popen("start /B ".$cmd, "r")); 

where $cmd is the string command for the program that you need to run (e.g. $cmd can equal notepad.exe or node Path\to\server.js).

Source: https://www.php.net/manual/en/function.exec.php (see Arno van den Brink's note in the section titled "User Contributed Notes").

you should have three tables: users, comments and comment_users.

comment_users has just two fields: fk_user_id and fk_comment_id

That way you can keep your performance up to a maximum :)

Damir is correct,

Your subquery needs to ensure that dps_user.id equals um.profile_id, otherwise it will grab the top row which might, but probably not equal your id of 'u162231993'

Your query should look like this:

SELECT u.id, mbg.marker_value 
FROM dps_user u
LEFT JOIN 
    (SELECT TOP 1 m.marker_value, um.profile_id
     FROM dps_usr_markers um (NOLOCK)
         INNER JOIN dps_markers m (NOLOCK) 
             ON m.marker_id= um.marker_id AND 
                m.marker_key = 'moneyBackGuaranteeLength'
     WHERE u.id = um.profile_id
     ORDER BY m.creation_date
    ) MBG ON MBG.profile_id=u.id 
WHERE u.id = 'u162231993'

@DanielChapman gives a good explanation of serialVersionUID, but no solution. the solution is this: run the serialver program on all your old classes. put these serialVersionUID values in your current versions of the classes. as long as the current classes are serial compatible with the old versions, you should be fine. (note for future code: you should always have a serialVersionUID on all Serializable classes)

if the new versions are not serial compatible, then you need to do some magic with a custom readObject implementation (you would only need a custom writeObject if you were trying to write new class data which would be compatible with old code). generally speaking adding or removing class fields does not make a class serial incompatible. changing the type of existing fields usually will.

Of course, even if the new class is serial compatible, you may still want a custom readObject implementation. you may want this if you want to fill in any new fields which are missing from data saved from old versions of the class (e.g. you have a new List field which you want to initialize to an empty list when loading old class data).

if you want to fill all the column:

update 'column' set 'info' where keyID!=0;

shift double click on Windows then type "unused", you will find an option Remove unused Resources,
also

 android {
        buildTypes {
            release {
                minifyEnabled true
                shrinkResources true
            }
   }
}

when you set these settings on, AS will automatically remove unused resources.

As Alexander Jank mentioned <base href="http://www.example.com/default/"> is great. When using sub-domains e.g. default.example.com base works great, because the JS and CSS loads from the said sub-domain and is accessible to both default.example.com and example.com/default

When using the root path, and your JS and CSS files are located in example.com/css, or example.com/js, then the subdomain has no access and the root of the subdomain is not accessible, except using the base.

SELECT * FROM sample_table WHERE last_visit = DATE_FORMAT('2014-11-24 10:48:09','%Y-%m-%d %H:%i:%s')

Three slightly different answers depending how you look at the question:

1) Good enough for the exact question asked is Jonathan Leffler's solution, except that to round up to 16-aligned, you only need 15 extra bytes, not 16.

A:

/* allocate a buffer with room to add 0-15 bytes to ensure 16-alignment */
void *mem = malloc(1024+15);
ASSERT(mem); // some kind of error-handling code
/* round up to multiple of 16: add 15 and then round down by masking */
void *ptr = ((char*)mem+15) & ~ (size_t)0x0F;

B:

free(mem);

2) For a more generic memory allocation function, the caller doesn't want to have to keep track of two pointers (one to use and one to free). So you store a pointer to the 'real' buffer below the aligned buffer.

A:

void *mem = malloc(1024+15+sizeof(void*));
if (!mem) return mem;
void *ptr = ((char*)mem+sizeof(void*)+15) & ~ (size_t)0x0F;
((void**)ptr)[-1] = mem;
return ptr;

B:

if (ptr) free(((void**)ptr)[-1]);

Note that unlike (1), where only 15 bytes were added to mem, this code could actually reduce the alignment if your implementation happens to guarantee 32-byte alignment from malloc (unlikely, but in theory a C implementation could have a 32-byte aligned type). That doesn't matter if all you do is call memset_16aligned, but if you use the memory for a struct then it could matter.

I'm not sure off-hand what a good fix is for this (other than to warn the user that the buffer returned is not necessarily suitable for arbitrary structs) since there's no way to determine programatically what the implementation-specific alignment guarantee is. I guess at startup you could allocate two or more 1-byte buffers, and assume that the worst alignment you see is the guaranteed alignment. If you're wrong, you waste memory. Anyone with a better idea, please say so...

[Added: The 'standard' trick is to create a union of 'likely to be maximally aligned types' to determine the requisite alignment. The maximally aligned types are likely to be (in C99) 'long long', 'long double', 'void *', or 'void (*)(void)'; if you include <stdint.h>, you could presumably use 'intmax_t' in place of long long (and, on Power 6 (AIX) machines, intmax_t would give you a 128-bit integer type). The alignment requirements for that union can be determined by embedding it into a struct with a single char followed by the union:

struct alignment
{
    char     c;
    union
    {
        intmax_t      imax;
        long double   ldbl;
        void         *vptr;
        void        (*fptr)(void);
    }        u;
} align_data;
size_t align = (char *)&align_data.u.imax - &align_data.c;

You would then use the larger of the requested alignment (in the example, 16) and the align value calculated above.

On (64-bit) Solaris 10, it appears that the basic alignment for the result from malloc() is a multiple of 32 bytes.
]

In practice, aligned allocators often take a parameter for the alignment rather than it being hardwired. So the user will pass in the size of the struct they care about (or the least power of 2 greater than or equal to that) and all will be well.

3) Use what your platform provides: posix_memalign for POSIX, _aligned_malloc on Windows.

4) If you use C11, then the cleanest - portable and concise - option is to use the standard library function aligned_alloc that was introduced in this version of the language specification.

This error occurs because the default value is true for the Embed Interop Types property of the TestStand API Interop assembly referenced in the new project. To resolve this error, change the value of the Embed Interop Types property to False by following these steps: Select the TestStand Interop Assembly reference in the references section of your project in the Solution Explorer. Find the Embed Interop Types property in the Property Browser, and change the value to False

The correct sentence is: svnadmin deltify $PATH. do not forghet to delet the project or repository from the file svn-acl (if you use it). if you simply delete the folder of repository you may corrupt the svn directory depending on how your svn is configured in your environment.

I found this image most helpful for understanding frame, bounds, etc.

Also please note that frame.size != bounds.size when the image is rotated.

just indent your code correctly:

def determine_period(universe_array):
    period=0
    tmp=universe_array
    while True:
        tmp=apply_rules(tmp)#aplly_rules is a another function
        period+=1
        if numpy.array_equal(tmp,universe_array) is True:
            return period
        if period>12:  #i wrote this line to stop it..but seems its doesnt work....help..
            return 0
        else:   
            return period

You need to understand that the break statement in your example will exit the infinite loop you've created with while True. So when the break condition is True, the program will quit the infinite loop and continue to the next indented block. Since there is no following block in your code, the function ends and don't return anything. So I've fixed your code by replacing the break statement by a return statement.

Following your idea to use an infinite loop, this is the best way to write it:

def determine_period(universe_array):
    period=0
    tmp=universe_array
    while True:
        tmp=apply_rules(tmp)#aplly_rules is a another function
        period+=1
        if numpy.array_equal(tmp,universe_array) is True:
            break
        if period>12:  #i wrote this line to stop it..but seems its doesnt work....help..
            period = 0
            break

    return period

Consider a Windows app with FormA and FormB. FormA is the primary form and it displays FormB. Imagine FormB needing to pass data back to its parent.

If you did this:

class FormA 
{
    FormB fb = new FormB( this );

    ...
    fb.Show();
}

class FormB 
{
    FormA parent;

    public FormB( FormA parent )
    {
        this.parent = parent;
    }     
}

FormB is tightly coupled to FormA. FormB can have no other parent than that of type FormA.

If, on the other hand, you had FormB publish an event and have FormA subscribe to that event, then FormB could push data back through that event to whatever subscriber that event has. In this case then, FormB doesn't even know its talking back to its parent; through the loose coupling the event provides it's simply talking to subscribers. Any type can now be a parent to FormA.

I think that const solves the problem for most people looking for this anwwer. If you really need an immutable constant, look into the other answers. To keep everything organized I save all constants on a folder and then require the whole folder.

src/main.js file

const constants = require("./consts_folder");

src/consts_folder/index.js

const deal = require("./deal.js")
const note = require("./note.js")


module.exports = {
  deal,
  note
}

Ps. here the deal and note will be first level on the main.js

src/consts_folder/note.js

exports.obj = {
  type: "object",
  description: "I'm a note object"
}

Ps. obj will be second level on the main.js

src/consts_folder/deal.js

exports.str = "I'm a deal string"

Ps. str will be second level on the main.js

Final result on main.js file:

console.log(constants.deal); Ouput:

{ deal: { str: 'I\'m a deal string' },

console.log(constants.note); Ouput:

note: { obj: { type: 'object', description: 'I\'m a note object' } }

With the addition of androidx in Studio 3.0+ the Toolbar compatibility is now in a new library, accessible like this

import androidx.appcompat.widget.Toolbar

Now you can make use of sets to do that easily.

let a= ['a', 'a', 'a', 'a']; // true_x000D_
let b =['a', 'a', 'b', 'a'];// false_x000D_
_x000D_
console.log(new Set(a).size === 1);_x000D_
console.log(new Set(b).size === 1);

i'm not sure if i understand you, but to query the source code of your triggers, procedures, package and functions you can try with the "user_source" table.

select * from user_source

In newer versions of pycharm u can do simply by right clicking on the directory or python package from which you want to import a file, then click on 'Mark Directory As' -> 'Sources Root'

This is much like a previous answer but simpler to read:

def make_trie(words):
    trie = {}
    for word in words:
        head = trie
        for char in word:
            if char not in head:
                head[char] = {}
            head = head[char]
        head["_end_"] = "_end_"
    return trie

In my opinion, it's much cleaner and easier to understand if you extract the retrieval of environment variables into a utility (you probably want to include a check to fail fast if an environment variable is not set anyway), and then you can just mock the utility.

// util.js
exports.getEnv = (key) => {
    const value = process.env[key];
    if (value === undefined) {
      throw new Error(`Missing required environment variable ${key}`);
    }
    return value;
};

// app.test.js
const util = require('./util');
jest.mock('./util');

With Eclipse and Windows:

you have to copy 2 files - xxxPROJECTxxx.properties - log4j.properties here : C:\Eclipse\CONTENER\TOMCAT\apache-tomcat-7\lib

All the magic seems to be in

visitortime.getTimezoneOffset()

That's cool, I didn't know about that. Does it work in Internet Explorer etc? From there you should be able to use JavaScript to Ajax, set cookies whatever. I'd probably go the cookie route myself.

You'll need to allow the user to change it though. We tried to use geo-location (via maxmind) to do this a while ago, and it was wrong enough to make it not worth doing. So we just let the user set it in their profile, and show a notice to users who haven't set theirs yet.

An observablecollection can be a List

{
    BuchungsSatz item = BuchungsListe.ToList.Find(x => x.BuchungsAuftragId == DGBuchungenAuftrag.CurrentItem.Id);
}

try
{

    $conn = new PDO("sqlsrv:Server=$server_name;Database=$db_name;ConnectionPooling=0", "", "");
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

}
catch(PDOException $e)
{

    $e->getMessage();

}

I don't know where the hang comes from, but redirecting (or piping) commands into an interactive ssh is in general a recipe for problems. It is more robust to use the command-to-run-as-a-last-argument style and pass the script on the ssh command line:

ssh user@server 'DEP_ROOT="/home/matthewr/releases"
datestamp=$(date +%Y%m%d%H%M%S)
REL_DIR=$DEP_ROOT"/"$datestamp
if [ ! -d "$DEP_ROOT" ]; then
    echo "creating the root directory"
    mkdir $DEP_ROOT
fi
mkdir $REL_DIR'

(All in one giant '-delimited multiline command-line argument).

The pseudo-terminal message is because of your -t which asks ssh to try to make the environment it runs on the remote machine look like an actual terminal to the programs that run there. Your ssh client is refusing to do that because its own standard input is not a terminal, so it has no way to pass the special terminal APIs onwards from the remote machine to your actual terminal at the local end.

What were you trying to achieve with -t anyway?

If you are looking for a direct approach and using a local File in that case. Try

<div
style={{ background-image: 'url(' + Image + ')', background-size: 'auto' }}
/>

This is the case of JS with inline styling where Image is a local file that you must have imported with a path.

If you have Java 5, use char c = ...; String s = String.format ("\\u%04x", (int)c);

If your source isn't a Unicode character (char) but a String, you must use charAt(index) to get the Unicode character at position index.

Don't use codePointAt(index) because that will return 24bit values (full Unicode) which can't be represented with just 4 hex digits (it needs 6). See the docs for an explanation.

[EDIT] To make it clear: This answer doesn't use Unicode but the method which Java uses to represent Unicode characters (i.e. surrogate pairs) since char is 16bit and Unicode is 24bit. The question should be: "How can I convert char to a 4-digit hex number", since it's not (really) about Unicode.

Just as Martin Konecny's answer said, you need to change the versionCode to something higher.

Your previous version code was 28. it should be changed to 29.

According to the document on the android developer website. a version code is

An integer value that represents the version of the application code, relative to other versions.

So it should be related(by related I mean higher) to the previous versionCode as noted by the document:

you should make sure that each successive release of your application uses a greater value.

As mentioned again in the document

the android:versionCode value does not necessarily have a strong resemblance to the application release version that is visible to the user (see android:versionName, below)

So even though this is the release 2.0001 of your app, it does not necessarily mean that the versionCode is 2.

Hope this helps :)

Use the built-in isinstance() function.

import pandas as pd

def f(var):
    if isinstance(var, pd.DataFrame):
        print("do stuff")

You can clear DataGridView in this manner

dataGridView1.Rows.Clear();
dataGridView1.Refresh();

If it is databound then try this

dataGridView1.Rows.Clear() // If dgv is bound to datatable
dataGridView1.DataBind();

Try CTRL+P,CTRL+Q to turn interactive mode to daemon.

If this does not work and you attached through docker attach, you can detach by killing the docker attach process.

Better way is to use sig-proxy parameter to avoid passing the CTRL+C to your container :

docker attach --sig-proxy=false [container-name]

Same option is available for docker run command.

You can simply make it by REGEX:

Form:

<form method="post" action="" enctype="multipart/form-data">
    <div class="uploadExtensionError" style="display: none">Only PDF allowed!</div>
    <input type="file" name="item_file" />
    <input type="submit" id='submit' value="submit"/>
</form>

And java script validation:

<script>
    $('#submit').click(function(event) {
        var val = $('input[type=file]').val().toLowerCase();
        var regex = new RegExp("(.*?)\.(pdf|docx|doc)$");
        if(!(regex.test(val))) {
            $('.uploadExtensionError').show();
            event.preventDefault();
        }
    });
</script>

Cheers!

I'm using mariadb. When I try to put this line at /etc/my.cnf:

[mysqld]
tmpdir=/tmp 

It solved the error generated from website frontend related to /tmp. But, it has backend problem with /tmp. Example, when I try to rebuild mariadb from the backend, it couldn't read the /tmp dir, and then generated the similar error.

mysqldump: Couldn't execute 'show fields from `wp_autoupdate`': Can't create/write to file '/tmp/#sql_1680_0.MAI' (Errcode: 2 "No such file or directory") (1)

So this one work for both front end and back end:

1. mkdir /var/lib/mysql/tmp

2. chown mysql:mysql /var/lib/mysql/tmp

3. Add the following line into the [mysqld] section:

    tmpdir = /var/lib/mysql/tmp

4. Restart mysqld (eg. Centos7: systemctl restart mysqld)

If you want to iterate over every item in the array as if it were a flattened array, you can just do:

foreach (int i in array) {
    Console.Write(i);
}

which would print

123456

If you want to be able to know the x and y indexes as well, you'll need to do:

for (int x = 0; x < array.GetLength(0); x += 1) {
    for (int y = 0; y < array.GetLength(1); y += 1) {
        Console.Write(array[x, y]);
    }
}

Alternatively you could use a jagged array instead (an array of arrays):

int[][] array = new int[2][] { new int[3] {1, 2, 3}, new int[3] {4, 5, 6} };
foreach (int[] subArray in array) {
    foreach (int i in subArray) {
        Console.Write(i);
    }
}

or

int[][] array = new int[2][] { new int[3] {1, 2, 3}, new int[3] {4, 5, 6} };
for (int j = 0; j < array.Length; j += 1) {
    for (int k = 0; k < array[j].Length; k += 1) {
        Console.Write(array[j][k]);
    }
}

To add onto what Miguel Ping answered, here is another section from the documentation that answers this as well:

Short version: use an ApplicationContext unless you have a really good reason for not doing so. For those of you that are looking for slightly more depth as to the 'but why' of the above recommendation, keep reading.

(posting this for any future Spring novices who might read this question)

I guess you want user to be redirected to ~/AreaZ URL once (s)he has visited ~/ URL. I'd achieve by means of the following code within your root HomeController.

public class HomeController
{
    public ActionResult Index()
    {
        return RedirectToAction("ActionY", "ControllerX", new { Area = "AreaZ" });
    }
}

And the following route in Global.asax.

routes.MapRoute(
    "Redirection to AreaZ",
    String.Empty,
    new { controller = "Home ", action = "Index" }
);

or you could use this line:

 link.setAttribute('onClick', 'onClickLink('+i+')');

instead of this one:

link.onclick=  function() { onClickLink(i+'');};

Found the solution after some searching.

You need to add a <meta> tag in your <head> containing name="theme-color", with your HEX code as the content value. For example:

<meta name="theme-color" content="#999999" />

Update:

If the android device has native dark-mode enabled, then this meta tag is ignored.

Chrome for Android does not use the color on devices with native dark-mode enabled.

Python 3

• class MyClass(object): = New-style class
• class MyClass: = New-style class (implicitly inherits from object)

Python 2

• class MyClass(object): = New-style class
• class MyClass: = OLD-STYLE CLASS

Explanation:

When defining base classes in Python 3.x, you’re allowed to drop the object from the definition. However, this can open the door for a seriously hard to track problem…

Python introduced new-style classes back in Python 2.2, and by now old-style classes are really quite old. Discussion of old-style classes is buried in the 2.x docs, and non-existent in the 3.x docs.

The problem is, the syntax for old-style classes in Python 2.x is the same as the alternative syntax for new-style classes in Python 3.x. Python 2.x is still very widely used (e.g. GAE, Web2Py), and any code (or coder) unwittingly bringing 3.x-style class definitions into 2.x code is going to end up with some seriously outdated base objects. And because old-style classes aren’t on anyone’s radar, they likely won’t know what hit them.

So just spell it out the long way and save some 2.x developer the tears.

var fs = require("fs");
var filename = "./index.html";

function start(resp) {
    resp.writeHead(200, {
        "Content-Type": "text/html"
    });
    fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        resp.write(data);
        resp.end();
    });
}

The new keyword allocates memory on the Java heap. The heap is the main pool of memory, accessible to the whole of the application. If there is not enough memory available to allocate for that object, the JVM attempts to reclaim some memory from the heap with a garbage collection. If it still cannot obtain enough memory, an OutOfMemoryError is thrown, and the JVM exits.

The heap is split into several different sections, called generations. As objects survive more garbage collections, they are promoted into different generations. The older generations are not garbage collected as often. Because these objects have already proven to be longer lived, they are less likely to be garbage collected.

When objects are first constructed, they are allocated in the Eden Space. If they survive a garbage collection, they are promoted to Survivor Space, and should they live long enough there, they are allocated to the Tenured Generation. This generation is garbage collected much less frequently.

There is also a fourth generation, called the Permanent Generation, or PermGen. The objects that reside here are not eligible to be garbage collected, and usually contain an immutable state necessary for the JVM to run, such as class definitions and the String constant pool. Note that the PermGen space is planned to be removed from Java 8, and will be replaced with a new space called Metaspace, which will be held in native memory. reference:http://www.programcreek.com/2013/04/jvm-run-time-data-areas/

It was proposed to set a timeout and then assume load failure after a timeout.

setTimeout(fireCustomOnerror, 4000);

The problem with that approach is that the assumption is based on chance. After your timeout expires, the request is still pending. The request for the pending script may load, even after the programmer assumed that load won't happen.

If the request could be canceled, then the program could wait for a period, then cancel the request.

Currently there is a far simpler solution than the ones already provided. When running your application you just have to pass along the threaded=True parameter to the app.run() call, like:

app.run(host="your.host", port=4321, threaded=True)

Another option as per what we can see in the werkzeug docs, is to use the processes parameter, which receives a number > 1 indicating the maximum number of concurrent processes to handle:

• threaded – should the process handle each request in a separate thread?
• processes – if greater than 1 then handle each request in a new process up to this maximum number of concurrent processes.

Something like:

app.run(host="your.host", port=4321, processes=3) #up to 3 processes

More info on the run() method here, and the blog post that led me to find the solution and api references.

Note: on the Flask docs on the run() methods it's indicated that using it in a Production Environment is discouraged because (quote): "While lightweight and easy to use, Flask’s built-in server is not suitable for production as it doesn’t scale well."

However, they do point to their Deployment Options page for the recommended ways to do this when going for production.

IIF is a non-standard T-SQL function. It was added to SQL SERVER 2012, so that Access could migrate to SQL Server without refactoring the IIF's to CASE before hand. Once the Access db is fully migrated into SQL Server, you can refactor.

In addition to all the answers above:

If you are on Android 6.0+ (API Level 23+) you have to explicitly ask for permission to access external storage. Simply having

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

in your manifest won't be enough. You also have actively request the permission in your activity:

//check for permission
if(ContextCompat.checkSelfPermission(this,
            Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED){
    //ask for permission
    requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, READ_EXTERNAL_STORAGE_PERMISSION_CODE);
}

I recommend reading this: http://developer.android.com/training/permissions/requesting.html#perm-request

I had a similar problem and upon looking into it, it was simply a field in the actual table missing id (id was empty/null) - meaning when you try to make the id field the primary key it will result in error because the table contains a row with null value for the primary key.

This could be the fix if you see a temp table associated with the error. I was using SQL Server Management Studio.

• SQL a language for talking to the database. It lets you select data, mutate and create database objects (like tables, views, etc.), change database settings.
• PL-SQL a procedural programming language (with embedded SQL)
• T-SQL (procedural) extensions for SQL used by SQL Server

To make matplotlib inline by default in Jupyter (IPython 3):

1. Edit file ~/.ipython/profile_default/ipython_config.py

2. Add line c.InteractiveShellApp.matplotlib = 'inline'

Please note that adding this line to ipython_notebook_config.py would not work. Otherwise it works well with Jupyter and IPython 3.1.0

For those who struggled the same as me with laravel artisan console command that makes a lot of requests to same wsdl of external soap server and then after some time fails with Could not connect to host error.

The problem was because I was creating new SoapClient instance each time before request was made. Do not do that. Create it once and make each request from the same client.

Hope it helps.

Even if u use DailyRollingFileAppender like @gedevan suggested, u will still get logname.log.2008-10-10 (After a day, because the previous day log will get archived and the date will be concatenated to it's filename). So if u want .log at the end, u'll have to do it like this on the DatePattern:

log4j.appender.file.DatePattern='.'yyyy-MM-dd-HH-mm'.log'

Identify the real process programmatically

(when the process ID is shown as 4)

The answers here, as usual, expect a level of interactivity.

The problem is when something is listening through HTTP.sys; then, the PID is always 4 and, as most people find, you need some tool to find the real owner.

Here's how to identify the offending process programmatically. No TcpView, etc (as good as those tools are). Does rely on netsh; but then, the problem is usually related to HTTP.sys.

$Uri = "http://127.0.0.1:8989"    # for example


# Shows processes that have registered URLs with HTTP.sys
$QueueText = netsh http show servicestate view=requestq verbose=yes | Out-String

# Break into text chunks; discard the header
$Queues    = $QueueText -split '(?<=\n)(?=Request queue name)' | Select-Object -Skip 1

# Find the chunk for the request queue listening on your URI
$Queue     = @($Queues) -match [regex]::Escape($Uri -replace '/$')


if ($Queue.Count -eq 1)
{
    # Will be null if could not pick out exactly one PID
    $ProcessId = [string]$Queue -replace '(?s).*Process IDs:\s+' -replace '(?s)\s.*' -as [int]

    if ($ProcessId)
    {
        Write-Verbose "Identified process $ProcessId as the HTTP listener. Killing..."
        Stop-Process -Id $ProcessId -Confirm
    }
}

Your [hidden] will work but you need to check the css:

And the css:

[hidden] {
  display: none !important;
}

That should work as you want.

npm install material-design-icons

This is what you need:

 =NOT(ISERROR(MATCH(<cell in col A>,<column B>, 0)))  ## pseudo code

For the first cell of A, this would be:

 =NOT(ISERROR(MATCH(A2,$B$2:$B$5, 0)))

Enter formula (and drag down) as follows:

You will get:

Have you looked into ControlsFx Popover control.

import org.controlsfx.control.PopOver;
import org.controlsfx.control.PopOver.ArrowLocation;

private PopOver item;

final Scene scene = addItemButton.getScene();

final Point2D windowCoord = new Point2D(scene.getWindow()
        .getX(), scene.getWindow().getY());

final Point2D sceneCoord = new Point2D(scene.getX(), scene.
                getY());

final Point2D nodeCoord = addItemButton.localToScene(0.0,
                        0.0);
final double clickX = Math.round(windowCoord.getX()
    + sceneCoord.getY() + nodeCoord.getX());

final double clickY = Math.round(windowCoord.getY()
        + sceneCoord.getY() + nodeCoord.getY());
item.setContentNode(addItemScreen);
item.setArrowLocation(ArrowLocation.BOTTOM_LEFT);
item.setCornerRadius(4);                            
item.setDetachedTitle("Add New Item");
item.show(addItemButton.getParent(), clickX, clickY);

This is only an example but a PopOver sounds like it could accomplish what you want. Check out the documentation for more info.

Important note: ControlsFX will only work on JavaFX 8.0 b118 or later.

There's another, very secure method. It's client certificates. Know how servers present an SSL Cert when you contact them on https? Well servers can request a cert from a client so they know the client is who they say they are. Clients generate certs and give them to you over a secure channel (like coming into your office with a USB key - preferably a non-trojaned USB key).

You load the public key of the cert client certificates (and their signer's certificate(s), if necessary) into your web server, and the web server won't accept connections from anyone except the people who have the corresponding private keys for the certs it knows about. It runs on the HTTPS layer, so you may even be able to completely skip application-level authentication like OAuth (depending on your requirements). You can abstract a layer away and create a local Certificate Authority and sign Cert Requests from clients, allowing you to skip the 'make them come into the office' and 'load certs onto the server' steps.

Pain the neck? Absolutely. Good for everything? Nope. Very secure? Yup.

It does rely on clients keeping their certificates safe however (they can't post their private keys online), and it's usually used when you sell a service to clients rather then letting anyone register and connect.

Anyway, it may not be the solution you're looking for (it probably isn't to be honest), but it's another option.

According to the documentation AnimationSet

Represents a group of Animations that should be played together. The transformation of each individual animation are composed together into a single transform. If AnimationSet sets any properties that its children also set (for example, duration or fillBefore), the values of AnimationSet override the child values

AnimationSet mAnimationSet = new AnimationSet(false); //false means don't share interpolators

Pass true if all of the animations in this set should use the interpolator associated with this AnimationSet. Pass false if each animation should use its own interpolator.

ImageView imageView= (ImageView)findViewById(R.id.imageView);
Animation fadeInAnimation = AnimationUtils.loadAnimation(this, R.anim.fade_in);
Animation fadeOutAnimation = AnimationUtils.loadAnimation(this, R.anim.fade_out);
mAnimationSet.addAnimation(fadeInAnimation);
mAnimationSet.addAnimation(fadeOutAnimation);
imageView.startAnimation(mAnimationSet);

I hope this will help you.

Make the multiple axes first and pass them to the Pandas plot function, like:

fig, axs = plt.subplots(1,2)

df['korisnika'].plot(ax=axs[0])
df['osiguranika'].plot(ax=axs[1])

It still gives you 1 figure, but with two different plots next to each other.

If you use bpython, all your command history is by default saved to ~/.pythonhist.

To save the commands for later reusage you can copy them to a python script file:

$ cp ~/.pythonhist mycommands.py

Then edit that file to clean it up and put it under Python path (global or virtual environment's site-packages, current directory, mentioning in *.pth, or some other way).

To include the commands into your shell, just import them from the saved file:

>>> from mycommands import *

If your data has the names grouped as shown then you can use this formula in D2 copied down to get a total against the last entry for each name

=IF((A2=A3)*(B2=B3),"",SUM(C$2:C2)-SUM(D$1:D1))

See screenshot

you can add security provider by editing java.security by adding security.provider.=org.bouncycastle.jce.provider.BouncyCastleProvider

or add a line in your top of your class

Security.addProvider(new BouncyCastleProvider());

you can use below line to specify provider while specifying algorithms

Cipher cipher = Cipher.getInstance("AES", "SunJCE");

if you are using other provider like Bouncy Castle then

Cipher cipher =  Cipher.getInstance("AES", "BC");

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

One of the things you should remember when converting QString to std::string is the fact that QString is UTF-16 encoded while std::string... May have any encodings.

So the best would be either:

QString qs;

// Either this if you use UTF-8 anywhere
std::string utf8_text = qs.toUtf8().constData();

// or this if you're on Windows :-)
std::string current_locale_text = qs.toLocal8Bit().constData();

The suggested (accepted) method may work if you specify codec.

See: http://doc.qt.io/qt-5/qstring.html#toLatin1

Note: if you need to use sudo, do this:

sudo bash -c 'cat file2 >> file1'

The usual method of simply prepending sudo to the command will fail, since the privilege escalation doesn't carry over into the output redirection.

I got a problem The type Initializer.. my config file resolved it..

i forgot to have a connection element like this
"connectionStrings" "/connectionStrings" maybe it depends on what you did in a code. my error is i cant open a class because of this connection element.

yes,the sorting proceed differently. in first scenario, orders based on column1 and in addition to that process further by sorting colmun2 based on column1 .. in second scenario ,it orders completely based on column 1 only... please proceed with a simple example...u will get quickly..

%__CD__% , %CD% , %=C:%

There's also another dynamic variable %__CD__% which points to the current directory but alike %CD% it has a backslash at the end. This can be useful if you want to append files to the current directory.

With %=C:% %=D:% you can access the last accessed directory for the corresponding drive. If the variable is not defined you haven't accessed the drive on the current cmd session.

And %__APPDIR__% expands to the executable that runs the current script a.k.a. cmd.exe directory.

Embrace the future! Just to be complete, you can also do this the Python 3k way by using the print function:

from __future__ import print_function  # Py 2.6+; In Py 3k not needed

mylist = ['10', 12, '14']    # Note that 12 is an int

print(*mylist,sep='\n')

Prints:

10
12
14

Eventually, print as Python statement will go away... Might as well start to get used to it.

%d is for integers use %f instead, it works for both float and double types:

double d = 1.2;
float f = 1.2f;
System.out.printf("%f %f",d,f); // prints 1.200000 1.200000

short answer, specific to OAuth2,

• HS256 user client secret to generate the token signature and same secret is required to validate the token in back-end. So you should have a copy of that secret in your back-end server to verify the signature.
• RS256 use public key encryption to sign the token.Signature(hash) will create using private key and it can verify using public key. So, no need of private key or client secret to store in back-end server, but back-end server will fetch the public key from openid configuration url in your tenant (https://[tenant]/.well-known/openid-configuration) to verify the token. KID parameter inside the access_toekn will use to detect the correct key(public) from openid-configuration.

For a new project select the home directory of the jdk

eg C:\Java\jdk1.7.0_99 or C:\Program Files\Java\jdk1.7.0_99

For an existing project.

1) You need to have a jdk installed on the system.

for instance in

C:\Java\jdk1.7.0_99

2) go to project structure under File menu ctrl+alt+shift+S

3) SDKs is located under Platform Settings. Select it.

4) click the green + up the top of the window.

5) select JDK (I have to use keyboard to select it do not know why).

select the home directory for your jdk installation.

should be good to go.

If you can use PL/SQL, try (EDIT: Incorporates Neil's xlnt suggestion to start at next higher value):

SELECT 'CREATE SEQUENCE transaction_sequence MINVALUE 0 START WITH '||MAX(trans_seq_no)+1||' INCREMENT BY 1 CACHE 20'
  INTO v_sql
  FROM transaction_log;

EXECUTE IMMEDIATE v_sql;

Another point to consider: By setting the CACHE parameter to 20, you run the risk of losing up to 19 values in your sequence if the database goes down. CACHEd values are lost on database restarts. Unless you're hitting the sequence very often, or, you don't care that much about gaps, I'd set it to 1.

One final nit: the values you specified for CACHE and INCREMENT BY are the defaults. You can leave them off and get the same result.

This may be a very late answer. in operator checks for memberships. That is, it checks if its left operand is a member of its right operand. In this case, raw_input() returns an str object of what is supplied by the user at the standard input. So, the if condition checks whether the input contains substrings "0" or "1". Considering the typecasting (int()) in the following line, the if condition essentially checks if the input contains digits 0 or 1.

you could also do it this way, in my case i use it before and after an h1 (brute force it ehehehe)

.titleImage::before {
content: "--------";
letter-spacing: -3px;
}

.titreImage::after {
content: "--------";
letter-spacing: -3px;
}

If the letter spacing makes it so the line get in the text just use a margin to push it away!

You could try using df['column'].str. and then use any string function. Pandas documentation includes those like split

Yes, you are using it incorrectly, Series.replace() is not inplace operation by default, it returns the replaced dataframe/series, you need to assign it back to your dataFrame/Series for its effect to occur. Or if you need to do it inplace, you need to specify the inplace keyword argument as True Example -

data['sex'].replace(0, 'Female',inplace=True)
data['sex'].replace(1, 'Male',inplace=True)

Also, you can combine the above into a single replace function call by using list for both to_replace argument as well as value argument , Example -

data['sex'].replace([0,1],['Female','Male'],inplace=True)

Example/Demo -

In [10]: data = pd.DataFrame([[1,0],[0,1],[1,0],[0,1]], columns=["sex", "split"])

In [11]: data['sex'].replace([0,1],['Female','Male'],inplace=True)

In [12]: data
Out[12]:
      sex  split
0    Male      0
1  Female      1
2    Male      0
3  Female      1

You can also use a dictionary, Example -

In [15]: data = pd.DataFrame([[1,0],[0,1],[1,0],[0,1]], columns=["sex", "split"])

In [16]: data['sex'].replace({0:'Female',1:'Male'},inplace=True)

In [17]: data
Out[17]:
      sex  split
0    Male      0
1  Female      1
2    Male      0
3  Female      1

you can remove last comma from a string by using slice() method, find the below example:

var strVal = $.trim($('.txtValue').val());
var lastChar = strVal.slice(-1);
if (lastChar == ',') {
    strVal = strVal.slice(0, -1);
}

Here is an Example

function myFunction() {_x000D_
 var strVal = $.trim($('.txtValue').text());_x000D_
 var lastChar = strVal.slice(-1);_x000D_
 if (lastChar == ',') { // check last character is string_x000D_
  strVal = strVal.slice(0, -1); // trim last character_x000D_
  $("#demo").text(strVal);_x000D_
 }_x000D_
}

Have only tried this on Mac:

• Create a data directory in the root folder of your app
• cd into your wherever you placed your mongo directory when you installed it

• run this command:

  mongod --dbpath ~/path/to/your/app/data

You should be good to go!

You can also use something like the code below. I used lombok to avoid writing some of the boilerplate codes for getters and constructor.

@AllArgsConstructor
@Getter
public enum RetroDeviceStatus {
    DELIVERED(0,"Delivered"),
    ACCEPTED(1, "Accepted"),
    REJECTED(2, "Rejected"),
    REPAIRED(3, "Repaired");

    private final Integer value;
    private final String stringValue;

    @Override
    public String toString() {
        return this.stringValue;
    }
}

All you need - add another key and use it.

Go to the metadata directory as below

Restart eclipse and rebuild project. It worked for me !

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

To my surprise, clearing temp files located in the %TEMP% directory resolved the issue for me.

Note: This path is generally at C:\Users\(yourusername)\AppData\Local\Temp

As @Warren-P included, you can navigate to the temp folder by putting in %temp% in Start Menu, or launch "File Explorer" and enter %temp% in the address bar.

The following is an example of how you might write and read a pickle file. Note that if you keep appending pickle data to the file, you will need to continue reading from the file until you find what you want or an exception is generated by reaching the end of the file. That is what the last function does.

import os
import pickle


PICKLE_FILE = 'pickle.dat'


def main():
    # append data to the pickle file
    add_to_pickle(PICKLE_FILE, 123)
    add_to_pickle(PICKLE_FILE, 'Hello')
    add_to_pickle(PICKLE_FILE, None)
    add_to_pickle(PICKLE_FILE, b'World')
    add_to_pickle(PICKLE_FILE, 456.789)
    # load & show all stored objects
    for item in read_from_pickle(PICKLE_FILE):
        print(repr(item))
    os.remove(PICKLE_FILE)


def add_to_pickle(path, item):
    with open(path, 'ab') as file:
        pickle.dump(item, file, pickle.HIGHEST_PROTOCOL)


def read_from_pickle(path):
    with open(path, 'rb') as file:
        try:
            while True:
                yield pickle.load(file)
        except EOFError:
            pass


if __name__ == '__main__':
    main()

static string ByteArrayToHexViaLookupPerByte2(byte[] bytes)
{                
        var result3 = new uint[bytes.Length];
        for (int i = 0; i < bytes.Length; i++)
                result3[i] = _Lookup32[bytes[i]];
        var handle = GCHandle.Alloc(result3, GCHandleType.Pinned);
        try
        {
                var result = Marshal.PtrToStringUni(handle.AddrOfPinnedObject(), bytes.Length * 2);
                return result;
        }
        finally
        {
                handle.Free();
        }
}

This functions in my tests is always the second entry after the unsafe implementation.

Unfortunately, the test bench is not so reliable... if you run it multiple times the list got shuffled so much that who knows after the unsafe which is really the fastest! It doesn't take into a account pre-warming, jit compilation time, and GC performance hits. I would like to have rewritten it to have more information, but I didn't had really the time for it.

Direct value should work just fine:

var sv = sel.value;
alert(sv);

The only reason your code might fail is when there is no item selected, then the selectedIndex returns -1 and the code breaks.

All of these are kinds of indices.

primary: must be unique, is an index, is (likely) the physical index, can be only one per table.

unique: as it says. You can't have more than one row with a tuple of this value. Note that since a unique key can be over more than one column, this doesn't necessarily mean that each individual column in the index is unique, but that each combination of values across these columns is unique.

index: if it's not primary or unique, it doesn't constrain values inserted into the table, but it does allow them to be looked up more efficiently.

fulltext: a more specialized form of indexing that allows full text search. Think of it as (essentially) creating an "index" for each "word" in the specified column.

In general you can concatenate a whole sequence of arrays along any axis:

numpy.concatenate( LIST, axis=0 )

but you do have to worry about the shape and dimensionality of each array in the list (for a 2-dimensional 3x5 output, you need to ensure that they are all 2-dimensional n-by-5 arrays already). If you want to concatenate 1-dimensional arrays as the rows of a 2-dimensional output, you need to expand their dimensionality.

As Jorge's answer points out, there is also the function stack, introduced in numpy 1.10:

numpy.stack( LIST, axis=0 )

This takes the complementary approach: it creates a new view of each input array and adds an extra dimension (in this case, on the left, so each n-element 1D array becomes a 1-by-n 2D array) before concatenating. It will only work if all the input arrays have the same shape—even along the axis of concatenation.

vstack (or equivalently row_stack) is often an easier-to-use solution because it will take a sequence of 1- and/or 2-dimensional arrays and expand the dimensionality automatically where necessary and only where necessary, before concatenating the whole list together. Where a new dimension is required, it is added on the left. Again, you can concatenate a whole list at once without needing to iterate:

numpy.vstack( LIST )

This flexible behavior is also exhibited by the syntactic shortcut numpy.r_[ array1, ...., arrayN ] (note the square brackets). This is good for concatenating a few explicitly-named arrays but is no good for your situation because this syntax will not accept a sequence of arrays, like your LIST.

There is also an analogous function column_stack and shortcut c_[...], for horizontal (column-wise) stacking, as well as an almost-analogous function hstack—although for some reason the latter is less flexible (it is stricter about input arrays' dimensionality, and tries to concatenate 1-D arrays end-to-end instead of treating them as columns).

Finally, in the specific case of vertical stacking of 1-D arrays, the following also works:

numpy.array( LIST )

...because arrays can be constructed out of a sequence of other arrays, adding a new dimension to the beginning.

This is how it is done using the fluent interface of the op4j Java library (1.1. was released Dec '10) :-

List<String> names = Op.onListFor("Ryan", "Julie", "Bob").get();

It's a very cool library that saves you a tonne of time.

Does Add to homescreen work on Chrome for iOS?

No.

Array.from() for details go to MDN

var a = "1,2,3,4";
var b = Array.from(a.split(','),Number);

b is an array of numbers

Since dates are converted to UNIX epoch (numbers), you can use Math.max/min to find those:

var maxDate = Math.max.apply(null, dates)
// convert back to date object
maxDate = new Date(maxDate)

(tested in chrome only, but should work in most browsers)

You have to call the function you want to be called on load (i.e., load of the document/page). For example, the function you want to load when document or page load is called "yourFunction". This can be done by calling the function on load event of the document. Please see the code below for more detail.

Try the code below:

<script src="js/jquery-1.11.0.min.js" type="text/javascript"></script>
<script type="text/javascript">

    $(document).ready(function () {
        yourFunction();
    });
    function yourFunction(){
      //some code
    }
</script>

I know this is an old thread, but for others looking, the above solutions are maybe not as good as the following, instead of checking change events, check the input events.

$("#myInput").on("input", function() {
    // Print entered value in a div box
    $("#result").text($(this).val());
});

A previous answer using LPAD() is optimal. However, in the event you want to do special or advanced processing, here is a method that allows more iterative control over the padding. Also serves as an example using other constructs to achieve the same thing.

UPDATE
    mytable
SET
    mycolumn = CONCAT(
        REPEAT(
            "0",
            8 - LENGTH(mycolumn)
        ),
        mycolumn
    )
WHERE
    LENGTH(mycolumn) < 8;

What @JosephSilber said, or pass the $event object into ng-click callback and stop the propagation inside of it:

<div ng-controller="OverlayCtrl" class="overlay" ng-click="hideOverlay()">
  <img src="http://some_src" ng-click="nextImage($event)"/>
</div>

$scope.nextImage = function($event) {
  $event.stopPropagation();
  // Some code to find and display the next image
}

Java 10 introduced List#copyOf which returns unmodifiable List while preserving the order:

List<Integer> list = List.copyOf(coll);

SHIFT

It's a way to iterate through a variable number of arguments passed into a script (or sub-routine) on the command line. In its simplest usage, it shifts %2 to be %1, %3 to be %2, and so-on. (You can also pass in a parameter to SHIFT to skip multiple arguments.) This makes the command "destructive" (i.e. %1 goes away forever), but it allows you to avoid hard-coding a maximum number of supported arguments.

Here's a short example to process command-line arguments one at a time:

:ParseArgs

if "%1"=="" (
    goto :DoneParsingArgs
)

rem ... do something with %1 ...

shift

goto :ParseArgs


:DoneParsingArgs

rem ...

ES6 supports now class & static keywords like a charm :

class Foo {
    constructor() {}

    talk() {
        console.log("i am not static");
    }

    static saying() {
        console.log(this.speech);
    }

    static get speech() {
        return "i am static method";
    }

}

This is meant as more of historical information than a "real" answer.

Remember that back in the day you had LOTS of unix like operating systems whose designers all had their own notion of where to put stuff, and sometimes didn't include Python, Perl, Bash, or lots of other GNU/Open Source stuff at all.

This was even true of different Linux distributions. On Linux--pre-FHS[1]-you might have python in /usr/bin/ or /usr/local/bin/. Or it might not have been installed, so you built your own and put it in ~/bin

Solaris was the worst I ever worked on, partially as the transition from Berkeley Unix to System V. You could wind up with stuff in /usr/, /usr/local/, /usr/ucb, /opt/ etc. This could make for some really long paths. I have memories of the stuff from Sunfreeware.com installing each package in it's own directory, but I can't recall if it symlinked the binaries into /usr/bin or not.

Oh, and sometimes /usr/bin was on an NFS server[2].

So the env utility was developed to work around this.

Then you could write #!/bin/env interpreter and as long as the path was proper things had a reasonable chance of running. Of course, reasonable meant (for Python and Perl) that you had also set the appropriate environmental variables. For bash/ksh/zsh it just worked.

This was important because people were passing around shell scripts (like perl and python) and if you'd hard coded /usr/bin/python on your Red Hat Linux workstation it was going to break bad on a SGI...well, no, I think IRIX put python in the right spot. But on a Sparc station it might not run at all.

I miss my sparc station. But not a lot. Ok, now you've got me trolling around on E-Bay. Bastages.

Here is a basic example of a global variable that the rest of your functions can access. Here is a live example for you: http://jsfiddle.net/fxCE9/

var myVariable = 'Hello';
alert('value: ' + myVariable);
myFunction1();
alert('value: ' + myVariable);
myFunction2();
alert('value: ' + myVariable);


function myFunction1() {
    myVariable = 'Hello 1';
}

function myFunction2() {
    myVariable = 'Hello 2';
}

If you are doing this within a jQuery ready() function then make sure your variable is inside the ready() function along with your other functions.

Simplest answer will be:

const firstDate = moment('2020/10/14'); // the date to be checked
const secondDate = moment('2020/10/15'); // the date to be checked

firstDate.startOf('day').diff(secondDate.startOf('day'), 'days'); // result = -1
secondDate.startOf('day').diff(firstDate.startOf('day'), 'days'); // result = 1

It will check with the midnight value and will return an accurate result. It will work also when time diff between two dates is less than 24 hours also.

"Clear" JavaScript:

function myKeyPress(e){
  var keynum;

  if(window.event) { // IE                  
    keynum = e.keyCode;
  } else if(e.which){ // Netscape/Firefox/Opera                 
    keynum = e.which;
  }

  alert(String.fromCharCode(keynum));
}

<input type="text" onkeypress="return myKeyPress(event)" />

JQuery:

$("input").keypress(function(event){
  alert(String.fromCharCode(event.which)); 
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input/>

I solve this problem from a different perspective.

I think if the server sends JSON data with Content-Type: text/html header. It doesn't mean the server guy intended to send you some html but accidentally changed to JSON. It does mean the server guy just doesn't care about what the Content-Type header is. So if the server guy doesn't care as the client side you better ignore the Content-Type header as well. To ignore the Content-Type header check in AFNetworking

manager.responseSerializer.acceptableContentTypes = nil;

In this way the AFJSONResponseSerializer (the default one) will serialize the JSON data without checking Content-Type in response header.

Sorry to wake the dead, but I thought someone might find this useful for future reference.

Here is how I handle it. It handles floating point numbers, but can easily be modified for integers.

Basically you can only press 0 - 9 and .

You can only have one 0 before the .

All other characters are ignored and the cursor position maintained.

    private bool _myTextBoxChanging = false;

    private void validateText(TextBox box)
    {
        // stop multiple changes;
        if (_myTextBoxChanging)
            return;
        _myTextBoxChanging = true;

        string text = box.Text;
        if (text == "")
            return;
        string validText = "";
        bool hasPeriod = false;
        int pos = box.SelectionStart;
        for (int i = 0; i < text.Length; i++ )
        {
            bool badChar = false;
            char s = text[i];
            if (s == '.')
            {
                if (hasPeriod)
                    badChar = true;
                else
                    hasPeriod = true;
            }
            else if (s < '0' || s > '9')
                badChar = true;

            if (!badChar)
                validText += s;
            else
            {
                if (i <= pos)
                    pos--;
            }
        }

        // trim starting 00s
        while (validText.Length >= 2 && validText[0] == '0')
        {
            if (validText[1] != '.')
            {
                validText = validText.Substring(1);
                if (pos < 2)
                    pos--;
            }
            else
                break;
        }

        if (pos > validText.Length)
            pos = validText.Length;
        box.Text = validText;
        box.SelectionStart = pos;
        _myTextBoxChanging = false;
    }

Here is a quickly modified int version:

    private void validateText(TextBox box)
    {
        // stop multiple changes;
        if (_myTextBoxChanging)
            return;
        _myTextBoxChanging = true;

        string text = box.Text;
        if (text == "")
            return;
        string validText = "";
        int pos = box.SelectionStart;
        for (int i = 0; i < text.Length; i++ )
        {
            char s = text[i];
            if (s < '0' || s > '9')
            {
                if (i <= pos)
                    pos--;
            }
            else
                validText += s;
        }

        // trim starting 00s 
        while (validText.Length >= 2 && validText.StartsWith("00")) 
        { 
            validText = validText.Substring(1); 
            if (pos < 2) 
                pos--; 
        } 

        if (pos > validText.Length)
            pos = validText.Length;
        box.Text = validText;
        box.SelectionStart = pos;
        _myTextBoxChanging = false;
    }

I have used something like the following in C++ code before:

#include <sstream>
int main()
{
    char* str = "1234";
    std::stringstream s_str( str );
    int i;
    s_str >> i;
}

Try using matplotlib.pyplot.ticklabel_format:

import matplotlib.pyplot as plt
...
plt.ticklabel_format(style='sci', axis='x', scilimits=(0,0))

This applies scientific notation (i.e. a x 10^b) to your x-axis tickmarks

These guys have an API that will give the results. It's also free to use.

Note: they also provide data source download in xls or sql format at a premium price. but these data also provides technical specifications for all the make model and trim options.

As Chemical Programer said in this comment, in latest DRF you can just do it like this:

class FooSerializer(serializers.ModelSerializer):
    extra_field = serializers.SerializerMethodField()

    def get_extra_field(self, foo_instance):
        return foo_instance.a + foo_instance.b

    class Meta:
        model = Foo
        fields = ('extra_field', ...)

Prepared statements / parameterized queries are generally sufficient to prevent 1st order injection on that statement^*. If you use un-checked dynamic sql anywhere else in your application you are still vulnerable to 2nd order injection.

2nd order injection means data has been cycled through the database once before being included in a query, and is much harder to pull off. AFAIK, you almost never see real engineered 2nd order attacks, as it is usually easier for attackers to social-engineer their way in, but you sometimes have 2nd order bugs crop up because of extra benign ' characters or similar.

You can accomplish a 2nd order injection attack when you can cause a value to be stored in a database that is later used as a literal in a query. As an example, let's say you enter the following information as your new username when creating an account on a web site (assuming MySQL DB for this question):

' + (SELECT UserName + '_' + Password FROM Users LIMIT 1) + '

If there are no other restrictions on the username, a prepared statement would still make sure that the above embedded query doesn't execute at the time of insert, and store the value correctly in the database. However, imagine that later the application retrieves your username from the database, and uses string concatenation to include that value a new query. You might get to see someone else's password. Since the first few names in users table tend to be admins, you may have also just given away the farm. (Also note: this is one more reason not to store passwords in plain text!)

We see, then, that prepared statements are enough for a single query, but by themselves they are not sufficient to protect against sql injection attacks throughout an entire application, because they lack a mechanism to enforce all access to a database within an application uses safe code. However, used as part of good application design — which may include practices such as code review or static analysis, or use of an ORM, data layer, or service layer that limits dynamic sql — prepared statements are the primary tool for solving the Sql Injection problem. If you follow good application design principles, such that your data access is separated from the rest of your program, it becomes easy to enforce or audit that every query correctly uses parameterization. In this case, sql injection (both first and second order) is completely prevented.

_{^*It turns out that MySql/PHP are (okay, were) just dumb about handling parameters when wide characters are involved, and there is still a rare case outlined in the other highly-voted answer here that can allow injection to slip through a parameterized query.}

Following link gives very good explanation on SaaS, PaaS and Iaas.. http://opensourceforgeeks.blogspot.in/2015/01/difference-between-saas-paas-and-iaas.html

Just some brief:

IaaS, here vendor provides infra to user where an user gets hardware/virtualization infra, storage and Networking infra.

PaaS, here vendor provides platform to user where an user gets all required things for their work like OS, Database, Execution Environment along with IaaS provided environment. So pass is platform + IaaS.

SaaS seems to be quite wide area where vendor provides almost everything from infra to platform to software. So SaaS is Iaas+PaaS along with different softwares like ms office, virtual box etc..

Don't use your browser to test your API.

Instead, try to use an HTTP client that allows you to specify your request, such as CURL, or even Fiddler.

The problem with this issue is in the client, not in the API. The web API behaves correctly, according to the browser's request.

You need a more specific expression. Try grep " OK$" or grep "[0-9]* OK". You want to choose a pattern that matches what you want, but won't match what you don't want. That pattern will depend upon what your whole file contents might look like.

You can also do: grep -w "OK" which will only match a whole word "OK", such as "1 OK" but won't match "1OK" or "OKFINE".

$ cat test.txt | grep -w "OK"
1 OK
2 OK
4 OK

I'm the author of iso8601 utils. It can be found on GitHub or on PyPI. Here's how you can parse your example:

>>> from iso8601utils import parsers
>>> parsers.datetime('2008-09-03T20:56:35.450686Z')
datetime.datetime(2008, 9, 3, 20, 56, 35, 450686)

Apparently some POST requests looks like a "GET" to the server (like Heroku...)

So I use this strategy and it works for me:

@RequestMapping(value = "/salvar", method = { RequestMethod.GET, RequestMethod.POST })

As Andrew Brower says, but adding a trim

ALTER PROCEDURE <Name>
(
    @PartialName VARCHAR(50) = NULL
)

SELECT Name 
    FROM <table>
    WHERE Name LIKE '%' + LTRIM(RTRIM(@PartialName)) + '%'

If I understand your question right you are asking what is difference if you register listener callback with $watch or if you do it with $observe.

Callback registerd with $watch is fired when $digest is executed.

Callback registered with $observe are called when value changes of attributes that contain interpolation (e.g. attr="{{notJetInterpolated}}").

Inside directive you can use both of them on very similar way:

    attrs.$observe('attrYouWatch', function() {
         // body
    });

or

    scope.$watch(attrs['attrYouWatch'], function() {
         // body
    });

Use ByteArrayInputStream:

InputStream is = new ByteArrayInputStream(decodedBytes);

AFAIK, fragments cannot hold other fragments.

UPDATE

With current versions of the Android Support package -- or native fragments on API Level 17 and higher -- you can nest fragments, by means of getChildFragmentManager(). Note that this means that you need to use the Android Support package version of fragments on API Levels 11-16, because even though there is a native version of fragments on those devices, that version does not have getChildFragmentManager().

Documentation here. Or if that doesn't work, try Google Code's GIT Documentation

IANAL but as I see it....

While you can combine GPL and MIT code, the GPL is tainting. Which means the package as a whole gets the limitations of the GPL. As that is more restrictive you can no longer use it in commercial (or rather closed source) software. Which also means if you have a MIT/BSD/ASL project you will not want to add dependencies to GPL code.

Adding a GPL dependency does not change the license of your code but it will limit what people can do with the artifact of your project. This is also why the ASF does not allow dependencies to GPL code for their projects.

I had a simular issue and resolved it using android:adjustViewBounds="true" on the ImageView.

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:contentDescription="@string/banner_alt"
    android:src="@drawable/banner_portrait" />

The iFrame attribute does not support percent in HTML5. It only supports pixels. http://www.w3schools.com/tags/att_iframe_height.asp

allow_url_fopen is generally set to On. If it is not On, then you can try two things.

1. Create an .htaccess file and keep it in root folder ( sometimes it may need to place it one step back folder of the root) and paste this code there.

   php_value allow_url_fopen On
   

2. Create a php.ini file (for update server php5.ini) and keep it in root folder (sometimes it may need to place it one step back folder of the root) and paste the following code there:

   allow_url_fopen = On;
   

I have personally tested the above solutions; they worked for me.

You can use HTML5 <figcaption>:

<figure>
  <img src="img.jpg" alt="my img"/>
  <figcaption> Your text </figcaption>
</figure>

Working example.

Demo:

function password_check() {_x000D_
  pass = document.getElementById("password").value;_x000D_
  console.log(pass);_x000D_
  regex = /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,}$/;_x000D_
  if (regex.exec(pass) == null) {_x000D_
    alert('invalid password!')_x000D_
  }_x000D_
  else {_x000D_
    console.log("valid");_x000D_
  }_x000D_
}

<input type="text" id="password" value="Sample@1">_x000D_
<input type="button" id="submit" onclick="password_check()" value="submit">

Whatever I understood from my learning and what I think it is is here. I am Quoting some part from a book i learnt this things. Nexus Repository Manager and Nexus Repository Manager OSS started as a repository manager supporting the Maven repository format. While it supports many other repository formats now, the Maven repository format is still the most common and well supported format for build and provisioning tools running on the JVM and beyond. This chapter shows example configurations for using the repository manager with Apache Maven and a number of other tools. The setups take advantage of merging many repositories and exposing them via a repository group. Setting this up is documented in the chapter in addition to the configuration used by specific tools.

What about this? I presume it can be counted on to handle dates before 1970 and after 2038.

target_date_time_ms = 200000 # or whatever
base_datetime = datetime.datetime( 1970, 1, 1 )
delta = datetime.timedelta( 0, 0, 0, target_date_time_ms )
target_date = base_datetime + delta

as mentioned in the Python standard lib:

fromtimestamp() may raise ValueError, if the timestamp is out of the range of values supported by the platform C localtime() or gmtime() functions. It’s common for this to be restricted to years in 1970 through 2038.

I just ran into this question and, while it is old, I figured I'd add an answer for the archives. The OP asked about for loops, but their goal was to gather a random sample of rows from the table. For that task, Postgres 9.5+ offers the TABLESAMPLE clause on WHERE. Here's a good rundown:

https://www.2ndquadrant.com/en/blog/tablesample-in-postgresql-9-5-2/

I tend to use Bernoulli as it's row-based rather than page-based, but the original question is about a specific row count. For that, there's a built-in extension:

https://www.postgresql.org/docs/current/tsm-system-rows.html

CREATE EXTENSION tsm_system_rows;

Then you can grab whatever number of rows you want:

select * from playtime tablesample system_rows (15);
