You use the "as" statement to avoid the possibility of an exception, e.g. you can handle the cast failure gracefully via logic. Only use the cast when you are sure that the object is of the desired type. I almost always use the "as" and then check for null.

Use regex in data annotation

[RegularExpression("([0-9]+)", ErrorMessage = "Please enter valid Number")]
public int MaxJsonLength { get; set; }

Here's a version using the excellent requests library:

from requests import session

payload = {
    'action': 'login',
    'username': USERNAME,
    'password': PASSWORD
}

with session() as c:
    c.post('http://example.com/login.php', data=payload)
    response = c.get('http://example.com/protected_page.php')
    print(response.headers)
    print(response.text)

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

Setup 1: compile your own glibc without dedicated GCC and use it

Since it seems impossible to do just with symbol versioning hacks, let's go one step further and compile glibc ourselves.

This setup might work and is quick as it does not recompile the whole GCC toolchain, just glibc.

But it is not reliable as it uses host C runtime objects such as crt1.o, crti.o, and crtn.o provided by glibc. This is mentioned at: https://sourceware.org/glibc/wiki/Testing/Builds?action=recall&rev=21#Compile_against_glibc_in_an_installed_location Those objects do early setup that glibc relies on, so I wouldn't be surprised if things crashed in wonderful and awesomely subtle ways.

For a more reliable setup, see Setup 2 below.

Build glibc and install locally:

export glibc_install="$(pwd)/glibc/build/install"

git clone git://sourceware.org/git/glibc.git
cd glibc
git checkout glibc-2.28
mkdir build
cd build
../configure --prefix "$glibc_install"
make -j `nproc`
make install -j `nproc`

Setup 1: verify the build

test_glibc.c

#define _GNU_SOURCE
#include <assert.h>
#include <gnu/libc-version.h>
#include <stdatomic.h>
#include <stdio.h>
#include <threads.h>

atomic_int acnt;
int cnt;

int f(void* thr_data) {
    for(int n = 0; n < 1000; ++n) {
        ++cnt;
        ++acnt;
    }
    return 0;
}

int main(int argc, char **argv) {
    /* Basic library version check. */
    printf("gnu_get_libc_version() = %s\n", gnu_get_libc_version());

    /* Exercise thrd_create from -pthread,
     * which is not present in glibc 2.27 in Ubuntu 18.04.
     * https://stackoverflow.com/questions/56810/how-do-i-start-threads-in-plain-c/52453291#52453291 */
    thrd_t thr[10];
    for(int n = 0; n < 10; ++n)
        thrd_create(&thr[n], f, NULL);
    for(int n = 0; n < 10; ++n)
        thrd_join(thr[n], NULL);
    printf("The atomic counter is %u\n", acnt);
    printf("The non-atomic counter is %u\n", cnt);
}

Compile and run with test_glibc.sh:

#!/usr/bin/env bash
set -eux
gcc \
  -L "${glibc_install}/lib" \
  -I "${glibc_install}/include" \
  -Wl,--rpath="${glibc_install}/lib" \
  -Wl,--dynamic-linker="${glibc_install}/lib/ld-linux-x86-64.so.2" \
  -std=c11 \
  -o test_glibc.out \
  -v \
  test_glibc.c \
  -pthread \
;
ldd ./test_glibc.out
./test_glibc.out

The program outputs the expected:

gnu_get_libc_version() = 2.28
The atomic counter is 10000
The non-atomic counter is 8674

Command adapted from https://sourceware.org/glibc/wiki/Testing/Builds?action=recall&rev=21#Compile_against_glibc_in_an_installed_location but --sysroot made it fail with:

cannot find /home/ciro/glibc/build/install/lib/libc.so.6 inside /home/ciro/glibc/build/install

so I removed it.

ldd output confirms that the ldd and libraries that we've just built are actually being used as expected:

+ ldd test_glibc.out
        linux-vdso.so.1 (0x00007ffe4bfd3000)
        libpthread.so.0 => /home/ciro/glibc/build/install/lib/libpthread.so.0 (0x00007fc12ed92000)
        libc.so.6 => /home/ciro/glibc/build/install/lib/libc.so.6 (0x00007fc12e9dc000)
        /home/ciro/glibc/build/install/lib/ld-linux-x86-64.so.2 => /lib64/ld-linux-x86-64.so.2 (0x00007fc12f1b3000)

The gcc compilation debug output shows that my host runtime objects were used, which is bad as mentioned previously, but I don't know how to work around it, e.g. it contains:

COLLECT_GCC_OPTIONS=/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/crt1.o

Setup 1: modify glibc

Now let's modify glibc with:

diff --git a/nptl/thrd_create.c b/nptl/thrd_create.c
index 113ba0d93e..b00f088abb 100644
--- a/nptl/thrd_create.c
+++ b/nptl/thrd_create.c
@@ -16,11 +16,14 @@
    License along with the GNU C Library; if not, see

+#include <stdio.h>
+
 #include "thrd_priv.h"

 int
 thrd_create (thrd_t *thr, thrd_start_t func, void *arg)
 {
+  puts("hacked");
   _Static_assert (sizeof (thr) == sizeof (pthread_t),
                   "sizeof (thr) != sizeof (pthread_t)");

Then recompile and re-install glibc, and recompile and re-run our program:

cd glibc/build
make -j `nproc`
make -j `nproc` install
./test_glibc.sh

and we see hacked printed a few times as expected.

This further confirms that we actually used the glibc that we compiled and not the host one.

Tested on Ubuntu 18.04.

Setup 2: crosstool-NG pristine setup

This is an alternative to setup 1, and it is the most correct setup I've achieved far: everything is correct as far as I can observe, including the C runtime objects such as crt1.o, crti.o, and crtn.o.

In this setup, we will compile a full dedicated GCC toolchain that uses the glibc that we want.

The only downside to this method is that the build will take longer. But I wouldn't risk a production setup with anything less.

crosstool-NG is a set of scripts that downloads and compiles everything from source for us, including GCC, glibc and binutils.

Yes the GCC build system is so bad that we need a separate project for that.

This setup is only not perfect because crosstool-NG does not support building the executables without extra -Wl flags, which feels weird since we've built GCC itself. But everything seems to work, so this is only an inconvenience.

Get crosstool-NG and configure it:

git clone https://github.com/crosstool-ng/crosstool-ng
cd crosstool-ng
git checkout a6580b8e8b55345a5a342b5bd96e42c83e640ac5
export CT_PREFIX="$(pwd)/.build/install"
export PATH="/usr/lib/ccache:${PATH}"
./bootstrap
./configure --enable-local
make -j `nproc`
./ct-ng x86_64-unknown-linux-gnu
./ct-ng menuconfig

The only mandatory option that I can see, is making it match your host kernel version to use the correct kernel headers. Find your host kernel version with:

uname -a

which shows me:

4.15.0-34-generic

so in menuconfig I do:

• Operating System
  • Version of linux

so I select:

4.14.71

which is the first equal or older version. It has to be older since the kernel is backwards compatible.

Now you can build with:

env -u LD_LIBRARY_PATH time ./ct-ng build CT_JOBS=`nproc`

and now wait for about thirty minutes to two hours for compilation.

Setup 2: optional configurations

The .config that we generated with ./ct-ng x86_64-unknown-linux-gnu has:

CT_GLIBC_V_2_27=y

To change that, in menuconfig do:

• C-library
• Version of glibc

save the .config, and continue with the build.

Or, if you want to use your own glibc source, e.g. to use glibc from the latest git, proceed like this:

• Paths and misc options
  • Try features marked as EXPERIMENTAL: set to true
• C-library
  • Source of glibc
    • Custom location: say yes
    • Custom location
      • Custom source location: point to a directory containing your glibc source

where glibc was cloned as:

git clone git://sourceware.org/git/glibc.git
cd glibc
git checkout glibc-2.28

Setup 2: test it out

Once you have built he toolchain that you want, test it out with:

#!/usr/bin/env bash
set -eux
install_dir="${CT_PREFIX}/x86_64-unknown-linux-gnu"
PATH="${PATH}:${install_dir}/bin" \
  x86_64-unknown-linux-gnu-gcc \
  -Wl,--dynamic-linker="${install_dir}/x86_64-unknown-linux-gnu/sysroot/lib/ld-linux-x86-64.so.2" \
  -Wl,--rpath="${install_dir}/x86_64-unknown-linux-gnu/sysroot/lib" \
  -v \
  -o test_glibc.out \
  test_glibc.c \
  -pthread \
;
ldd test_glibc.out
./test_glibc.out

Everything seems to work as in Setup 1, except that now the correct runtime objects were used:

COLLECT_GCC_OPTIONS=/home/ciro/crosstool-ng/.build/install/x86_64-unknown-linux-gnu/bin/../x86_64-unknown-linux-gnu/sysroot/usr/lib/../lib64/crt1.o

Setup 2: failed efficient glibc recompilation attempt

It does not seem possible with crosstool-NG, as explained below.

If you just re-build;

env -u LD_LIBRARY_PATH time ./ct-ng build CT_JOBS=`nproc`

then your changes to the custom glibc source location are taken into account, but it builds everything from scratch, making it unusable for iterative development.

If we do:

./ct-ng list-steps

it gives a nice overview of the build steps:

Available build steps, in order:
  - companion_tools_for_build
  - companion_libs_for_build
  - binutils_for_build
  - companion_tools_for_host
  - companion_libs_for_host
  - binutils_for_host
  - cc_core_pass_1
  - kernel_headers
  - libc_start_files
  - cc_core_pass_2
  - libc
  - cc_for_build
  - cc_for_host
  - libc_post_cc
  - companion_libs_for_target
  - binutils_for_target
  - debug
  - test_suite
  - finish
Use "<step>" as action to execute only that step.
Use "+<step>" as action to execute up to that step.
Use "<step>+" as action to execute from that step onward.

therefore, we see that there are glibc steps intertwined with several GCC steps, most notably libc_start_files comes before cc_core_pass_2, which is likely the most expensive step together with cc_core_pass_1.

In order to build just one step, you must first set the "Save intermediate steps" in .config option for the intial build:

• Paths and misc options
  • Debug crosstool-NG
    • Save intermediate steps

and then you can try:

env -u LD_LIBRARY_PATH time ./ct-ng libc+ -j`nproc`

but unfortunately, the + required as mentioned at: https://github.com/crosstool-ng/crosstool-ng/issues/1033#issuecomment-424877536

Note however that restarting at an intermediate step resets the installation directory to the state it had during that step. I.e., you will have a rebuilt libc - but no final compiler built with this libc (and hence, no compiler libraries like libstdc++ either).

and basically still makes the rebuild too slow to be feasible for development, and I don't see how to overcome this without patching crosstool-NG.

Furthermore, starting from the libc step didn't seem to copy over the source again from Custom source location, further making this method unusable.

Bonus: stdlibc++

A bonus if you're also interested in the C++ standard library: How to edit and re-build the GCC libstdc++ C++ standard library source?

1. Download the latest CMake Mac binary distribution here: https://cmake.org/download/ (current latest is: https://cmake.org/files/v3.17/cmake-3.17.1-Darwin-x86_64.dmg)

2. Double click the downloaded .dmg file to install it. In the window that pops up, drag the CMake icon into the Application folder.

3. Add this line to your .bashrc file: PATH="/Applications/CMake.app/Contents/bin":"$PATH"

4. Reload your .bashrc file: source ~/.bashrc

5. Verify the latest cmake version is installed: cmake --version

6. You can launch the CMake GUI by clicking on LaunchPad and typing cmake. Click on the CMake icon that appears.

//a[contains(@prop,'Foo')]

Works if I use this XML to get results back.

<bla>
 <a prop="Foo1">a</a>
 <a prop="Foo2">b</a>
 <a prop="3Foo">c</a>
 <a prop="Bar">a</a>
</bla>

Edit: Another thing to note is that while the XPath above will return the correct answer for that particular xml, if you want to guarantee you only get the "a" elements in element "bla", you should as others have mentioned also use

/bla/a[contains(@prop,'Foo')]

This will search you all "a" elements in your entire xml document, regardless of being nested in a "blah" element

//a[contains(@prop,'Foo')]  

I added this for the sake of thoroughness and in the spirit of stackoverflow. :)

It looks like get-pip.py has been updated to use the environment variables http_proxy and https_proxy.

Windows:

set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
python get-pip.py

Linux/OS X:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E python get-pip.py

However if this still doesn't work for you, you can always install pip through a proxy using setuptools' easy_install by setting the same environment variables.

Windows:

set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
easy_install pip

Linux/OS X:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E easy_install pip

Then once it's installed, use:

pip install --proxy="user:password@server:port" packagename

From the pip man page:

--proxy
Have pip use a proxy server to access sites. This can be specified using "user:[email protected]:port" notation. If the password is left out, pip will ask for it.

Just reboot the Ec2 Instance once you applied Rules

UPDATE: Now it's very simple to add HTML attributes to the default editor templates. It neans instead of doing this:

@Html.TextBoxFor(m => m.userCode, new { @readonly="readonly" })

you simply can do this:

@Html.EditorFor(m => m.userCode, new { htmlAttributes = new { @readonly="readonly" } })

Benefits: You haven't to call .TextBoxFor, etc. for templates. Just call .EditorFor.

While @Shark's solution works correctly, and it is simple and useful, my solution (that I use always) is this one: Create an editor-template that can handles readonly attribute:

1. Create a folder named EditorTemplates in ~/Views/Shared/
2. Create a razor PartialView named String.cshtml

3. Fill the String.cshtml with this code:

   @if(ViewData.ModelMetadata.IsReadOnly) {
       @Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue,
           new { @class = "text-box single-line readonly", @readonly = "readonly", disabled = "disabled" })
   } else {
       @Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue,
           new { @class = "text-box single-line" })
   }
   

4. In model class, put the [ReadOnly(true)] attribute on properties which you want to be readonly.

For example,

public class Model {
    // [your-annotations-here]
    public string EditablePropertyExample { get; set; }

    // [your-annotations-here]
    [ReadOnly(true)]
    public string ReadOnlyPropertyExample { get; set; }
}

Now you can use Razor's default syntax simply:

@Html.EditorFor(m => m.EditablePropertyExample)
@Html.EditorFor(m => m.ReadOnlyPropertyExample)

The first one renders a normal text-box like this:

<input class="text-box single-line" id="field-id" name="field-name" />

And the second will render to;

<input readonly="readonly" disabled="disabled" class="text-box single-line readonly" id="field-id" name="field-name" />

You can use this solution for any type of data (DateTime, DateTimeOffset, DataType.Text, DataType.MultilineText and so on). Just create an editor-template.

In our, the problem appeared after making changes in Debug -> myProject Properties -> Web, specifically changing the project URL and then closing VS. Upon reopening, VS had trouble parsing the new URL and so threw the error. Unfortunately, further configuration through the VS UI was not possible since the project won't load.

Since the file configuration changes are persisted in the myProject.csproj.user file, which lives in the project's root folder, the problem was easy to correct by simply removing the myProject.csproj.user file. At that point the project would load and the user file was then regenerated when the project was next run in debug mode.

Note, the project URL in the regenerated file had to be changed from the default http://localhost:58995 to the original https://localhost:44302 before the entire application could be accessed since we have the app locked down under SSL. Your ports may be different. This was done through VS under Debug -> myProject Properties -> Web after running the project.

Rachel's solution is working fine, although you need to use the third party script from raw.githubusercontent.com

By now there is a feature they show on the landing page when advertisng the "modular" script. You can see a legend there with this structure:

<div class="labeled-chart-container">
    <div class="canvas-holder">
        <canvas id="modular-doughnut" width="250" height="250" style="width: 250px; height: 250px;"></canvas>
    </div>

<ul class="doughnut-legend">
    <li><span style="background-color:#5B90BF"></span>Core</li>
    <li><span style="background-color:#96b5b4"></span>Bar</li>
    <li><span style="background-color:#a3be8c"></span>Doughnut</li>
    <li><span style="background-color:#ab7967"></span>Radar</li>
    <li><span style="background-color:#d08770"></span>Line</li>
    <li><span style="background-color:#b48ead"></span>Polar Area</li>
</ul>
</div>

To achieve this they use the chart configuration option legendTemplate

legendTemplate : "<ul class=\"<%=name.toLowerCase()%>-legend\"><% for (var i=0; i<segments.length; i++){%><li><span style=\"background-color:<%=segments[i].fillColor%>\"></span><%if(segments[i].label){%><%=segments[i].label%><%}%></li><%}%></ul>"

You can find the doumentation here on chartjs.org This works for all the charts although it is not part of the global chart configuration.

Then they create the legend and add it to the DOM like this:

var legend = myPie.generateLegend();
$("#legend").html(legend);

Simply you can use this method:

1. If you have a database with same name: WIN+R -> services.msc -> SQL SERVER(MSSQLSERVER) -> Stop
2. Go to your MySQL Data folder path and delete previews database files
3. Start sql service
4. Right click on database and select Restore database
5. in Files tab change Data file folder and Log file folder
6. Click on OK to restore your database

my problem was solved with this method BY...

The algorithm has 4 simple steps:

1. Divide the array into 3 different parts: left, pivot and right, where pivot will have only one element. Let us choose this pivot element as the first element of array
2. Append elements to the respective part by comparing them to pivot element. (explanation in comments)
3. Recurse this algorithm till all elements in the array have been sorted
4. Finally, join left+pivot+right parts

Code for the algorithm in python:

def my_sort(A):

      p=A[0]                                       #determine pivot element. 
      left=[]                                      #create left array
      right=[]                                     #create right array
      for i in range(1,len(A)):
        #if cur elem is less than pivot, add elem in left array
        if A[i]< p:
          left.append(A[i])         
          #the recurssion will occur only if the left array is atleast half the size of original array
          if len(left)>1 and len(left)>=len(A)//2:          
              left=my_sort(left)                            #recursive call
        elif A[i]>p: 
          right.append(A[i])                                #if elem is greater than pivot, append it to right array
          if len(right)>1 and len(right)>=len(A)//2:        # recurssion will occur only if length of right array is atleast the size of original array
              right=my_sort(right)
     A=left+[p]+right                                        #append all three part of the array into one and return it
     return A

my_sort([12,4,5,6,7,3,1,15])

Carry on with this algorithm recursively with the left and right parts.

While creating a project from a full folder may or may not work within the workspace, there's a condition outside of the workspace that prevents starting a new project with a full folder.

This is relevant if you use numerous folder locations for sources, for example an htdocs or www folder for web projects, and a different location for desktop Java applications.

The condition mentioned occurs when Eclipse is told to create a new project, and given a full folder outside the workspace. Eclipse will say the folder isn't empty, and prevent creating a new project within the given folder. I haven't found a way around this, and any solution requires extra steps.

My favorite solution is as follows

1. Rename the full folder with an appended "Original" or "Backup.
2. Create the Eclipse project with the name of the full folder before the folder was renamed.
3. Copy all the relabeled full folders contents into the new project folder.

Eclipse should make a new project, and update that project with the new folder contents as it scans for changes. The existing sources are now part of the new project.

Although you had to perform three extra steps, you now have a backup with the original sources available, and are also able to use a copy of them in an existing project. If storage space is a concern, simply move/cut the source rather than fully copy the original folder contents.

I had this error with Visual Studion 2019, my project was NopCommerce 4.30 which is an ASP.Net Core 3.1 project. I added page "gouden-munten-buitenland" to be the starting page and I only got the error when going to that page. Turned out that Visual Studio generated an invalid applicationHost.config :

<applicationPools>
    ....
    <add name="gouden-munten-buitenland AppPool" autoStart="true" />
    <add name="gouden-munten-buitenland AppPool 2" autoStart="true" /> <!-- WRONG -->
    <add name="Nop.Web AppPool" managedRuntimeVersion="" />
    <applicationPoolDefaults managedRuntimeVersion="v4.0">
    <processModel loadUserProfile="true" setProfileEnvironment="false" />
    </applicationPoolDefaults>
</applicationPools>

and

<sites>
    ....
    <site name="Nop.Web" id="2">
    ...
    <application path="/gouden-munten-buitenland/gouden-munten-buitenland" applicationPool="gouden-munten-buitenland AppPool">
        <virtualDirectory path="/" physicalPath="C:\Usr\Stephan\Wrk\Kevelam\kNop.430\Presentation\Nop.Web" />
    </application>
    <application path="/gouden-munten-buitenland" applicationPool="gouden-munten-buitenland AppPool 2">
        <virtualDirectory path="/" physicalPath="C:\Usr\Stephan\Wrk\Kevelam\kNop.430\Presentation\Nop.Web" />
    </application> <!-- WRONG -->
    ....
    </site>
    ...
</sites>

I removed the nodes identified as 'WRONG' and then it worked.

Also as important is to make sure that, your database name matches the data base name in the backup you are trying to restore. If it does not match, you will get the same error.

In your link function, do this:

// link function
function (scope, element, attrs) {
  var myEl = angular.element(element[0].querySelector('.list-scrollable'));
}

Also, in your link function, don't name your scope variable using a $. That is an angular convention that is specific to built in angular services, and is not something that you want to use for your own variables.

WHERE project.project_name='Trail' and  create_test.project_name ='Trail' and project.uid= create_test.uid = '1';

If anyone cares, for NTEXT, use the following format:

SELECT CAST(REPLACE(CAST([ColumnValue] AS NVARCHAR(MAX)),'find','replace') AS NTEXT) 
    FROM [DataTable]

I had a similar problem just recently. The way it worked for me it was realizing that "setup.py" was wrong

Previously I deleted my previous src folder, and added a new one with other name, but I didn't change anything on the setup.py (newbie mistake I guess).

So pointing setup.py to the right packages folder did the trick for me

from setuptools import find_packages, setup

setup(
    name="-> YOUR SERVICE NAME <-",
    extras_Require=dict(test=["pytest"]),
    packages=find_packages(where="->CORRECT FOLDER<-"),
    package_dir={"": "->CORRECT FOLDER<-"},
)

Also, not init.py in test folder nor in the root one.

Hope it helps someone =)

Best!

WebApiConfig.Register(GlobalConfiguration.Configuration);

Should be first in App_start event. I have tried it at last position in APP_start event, but that did not work.

There are two ways to do this.

1. providing the SHA of the commit you want to see to git log

git log -p a2c25061

Where -p is short for patch

2. use git show

git show a2c25061

The output for both commands will be:

• the commit
• the author
• the date
• the commit message
• the patch information

It's faster than RegEx.

$input = "0987654321"; 

$output = substr($input, -10, -7) . "-" . substr($input, -7, -4) . "-" . substr($input, -4); 
echo $output;

I recommend to read this entire article, but here is the most relevant section that addresses your question:

Rollback and Error Handling is Difficult

In my articles on Error and Transaction Handling in SQL Server, I suggest that > you should always have an error handler like

BEGIN CATCH
   IF @@trancount > 0 ROLLBACK TRANSACTION
   EXEC error_handler_sp
   RETURN 55555
END CATCH

The idea is that even if you do not start a transaction in the procedure, you should always include a ROLLBACK, because if you were not able to fulfil your contract, the transaction is not valid.

Unfortunately, this does not work well with INSERT-EXEC. If the called procedure executes a ROLLBACK statement, this happens:

Msg 3915, Level 16, State 0, Procedure SalesByStore, Line 9 Cannot use the ROLLBACK statement within an INSERT-EXEC statement.

The execution of the stored procedure is aborted. If there is no CATCH handler anywhere, the entire batch is aborted, and the transaction is rolled back. If the INSERT-EXEC is inside TRY-CATCH, that CATCH handler will fire, but the transaction is doomed, that is, you must roll it back. The net effect is that the rollback is achieved as requested, but the original error message that triggered the rollback is lost. That may seem like a small thing, but it makes troubleshooting much more difficult, because when you see this error, all you know is that something went wrong, but you don't know what.

Try this:

String newString = "";
Sting oldString = "/Users/smcho/filegen_from_directory/AIRPassthrough";

int indexOfLastSlash = oldString.LastIndexOf('/', 0, oldString.length());

newString = oldString.subString(indexOfLastSlash, oldString.length());

Code may be off (I haven't tested it) but the idea should work

There's a :data() filter plugin that does just this :)

Some examples based on your question:

$('a:data("category=music")')
$('a:data("user.name.first=Tom")');
$('a:data("category=music"):data("artist.name=Madonna")');
//jQuery supports multiple of any selector to restrict further, 
//just chain with no space in-between for this effect

The performance isn't going to be extremely great compared to what's possible, selecting from $._cache and grabbing the corresponding elements is by far the fastest, but a lot more round-about and not very "jQuery-ey" in terms of how you get to stuff (you usually come in from the element side). Of th top of my head, I'm not sure this is fastest anyway since the process of going from unique Id to element is convoluted in itself, in terms of performance.

The comparison selector you mentioned will be best to do in a .filter(), there's no built-in support for this in the plugin, though you could add it in without a lot of trouble.

If you want to run .py files in Windows, Try installing Git bash Then download python(Required Version) from python.org and install in the main c drive folder

For me, its :

"C:\Python38"

then open Git Bash and go to the respective folder where your .py file is stored :

For me, its :

File Location : "Downloads" File Name : Train.py

So i changed my Current working Directory From "C:/User/(username)/" to "C:/User/(username)/Downloads"

then i will run the below command

" /c/Python38/python Train.py "

and it will run successfully.

But if it give the below error :

from sklearn.model_selection import train_test_split ModuleNotFoundError: No module named 'sklearn'

Then Do not panic :

and use this command :

" /c/Python38/Scripts/pip install sklearn "

and after it has installed sklearn go back and run the previous command :

" /c/Python38/python Train.py "

and it will run successfully.

!!!!HAPPY LEARNING !!!!

Update

This answer is, as I write this, nearly eight years old, and about five years stale. But it's still (as I write this) the "accepted" answer, because it answered the question when it was asked.

The newer answer, that applies to the newer Android Studio tools, can be found here: https://stackoverflow.com/a/35828035/62 -- it's a great answer with screen shots. If you're using Android Studio, ignore the Eclipse answer below.

Original Eclipse-based Answer

I was searching for the answer to this question, and was unsatisfied with the above answers. But then I found the answer, so here it is for future reference:

To summarize (and clarify), in Eclipse, go to "Debug Configurations". You can find that in the drop-down under the "debug" icon. Select "target", and select a preferred emulator target to launch. Then under "additional emulator command line options," add this:

-partition-size 1024

Then CLOSE the emulator (and remove any devices), and click the debug icon, which will launch the preferred emulator you selected. This is important: Eclipse needs to launch the debugger, not AVD.

That fixed the problem for me.

Try this,

 body.modal-open {
    overflow: hidden;
    position:fixed;
    width: 100%;
}

yet another edit: As of version 5.2 pluck is not deprecated anymore, it just got new behaviour (same as lists previously - see side-note below):

edit: As of version 5.1 pluck is deprecated, so start using value instead:

DB::table('users')->where('username', $username)->value('groupName');    

// valid for L4 / L5.0 only
DB::table('users')->where('username', $username)->pluck('groupName');

this will return single value of groupName field of the first row found.

SIDE NOTE reg. @TomasButeler comment: As Laravel doesn't follow sensible versioning, there are sometimes cases like this. At the time of writing this answer we had pluck method to get SINGLE value from the query (Laravel 4.* & 5.0).

Then, with L5.1 pluck got deprecated and, instead, we got value method to replace it.

But to make it funny, pluck in fact was never gone. Instead it just got completely new behaviour and... deprecated lists method.. (L5.2) - that was caused by the inconsistency between Query Builder and Collection methods (in 5.1 pluck worked differently on the collection and query, that's the reason).

The answers above seem partly outdated.

The URL builder on https://developers.facebook.com/docs/plugins/like-button/ worked nicely for me.

You can configure, preview and the get the code/URL in different flavors: HTML5, XFBML, IFRAME, URL

I use this funcion:

DATEDIFF("31/01/2016", "01/03/2016") // me return 30 days

my function:

import java.util.Date;

public long DATEDIFF(String date1, String date2) {
        long MILLISECS_PER_DAY = 24 * 60 * 60 * 1000;
        long days = 0l;
        SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy"); // "dd/MM/yyyy HH:mm:ss");

        Date dateIni = null;
        Date dateFin = null;        
        try {       
            dateIni = (Date) format.parse(date1);
            dateFin = (Date) format.parse(date2);
            days = (dateFin.getTime() - dateIni.getTime())/MILLISECS_PER_DAY;                        
        } catch (Exception e) {  e.printStackTrace();  }   

        return days; 
     }

Seaborn box plot returns a matplotlib axes instance. Unlike pyplot itself, which has a method plt.title(), the corresponding argument for an axes is ax.set_title(). Therefore you need to call

sns.boxplot('Day', 'Count', data= gg).set_title('lalala')

A complete example would be:

import seaborn as sns
import matplotlib.pyplot as plt

tips = sns.load_dataset("tips")
sns.boxplot(x=tips["total_bill"]).set_title("LaLaLa")

plt.show()

Of course you could also use the returned axes instance to make it more readable:

ax = sns.boxplot('Day', 'Count', data= gg)
ax.set_title('lalala')
ax.set_ylabel('lololo')

If you have problem with libclntsh.so, need create symlink for libclntsh.so from /usr/lib/oracle/11.2/client64/lib to /usr/lib

What about using ternary operator?

<?php
 // Example usage for: Ternary Operator
 $action = (empty($_POST['action'])) ? 'default' : $_POST['action'];
?>

Which is identical to this if/else statement:

<?php
 if (empty($_POST['action'])) {
   $action = 'default';
 } else {
   $action = $_POST['action'];
 }
?>

This answer is quite old. pguardiario's got it.

One site to check out is JSON implementation for Ruby. This site offers a gem you can install for a much faster C extension variant.

With the benchmarks given their documentation page they claim that it is 21.500x faster than ActiveSupport::JSON.decode

The code would be the same as Milan Novota's answer with this gem, but the parsing would just be:

parsed_json = JSON(your_json_string)

You shouldn't be using .findall() at all - .search() is what you want. It finds the leftmost match, which is what you want (or returns None if no match exists).

m = re.search(pattern, text)
result = m.group(0) if m else ""

Whether you want to put that in a function is up to you. It's unusual to want to return an empty string if no match is found, which is why nothing like that is built in. It's impossible to get confused about whether .search() on its own finds a match (it returns None if it didn't, or an SRE_Match object if it did).

Simply pass latitude, longitude and your Google API Key to the following query string, you will get a json array, fetch your city from there.

https://maps.googleapis.com/maps/api/geocode/json?latlng=44.4647452,7.3553838&key=YOUR_API_KEY

Note: Ensure that no space exists between the latitude and longitude values when passed in the latlng parameter.

Click here to get an API key

console.log(Math.floor(100000 + Math.random() * 900000));

Will always create a number of 6 digits and it ensures the first digit will never be 0. The code in your question will create a number of less than 6 digits.

You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -, like script.ps1 -server http://devserver

Then you handle them in param section in the beginning of the file.

You can also assign default values to your params, read them from console if not available or stop script execution:

 param (
    [string]$server = "http://defaultserver",
    [Parameter(Mandatory=$true)][string]$username,
    [string]$password = $( Read-Host "Input password, please" )
 )

Inside the script you can simply

write-output $server

since all parameters become variables available in script scope.

In this example, the $server gets a default value if the script is called without it, script stops if you omit the -username parameter and asks for terminal input if -password is omitted.

Update: You might also want to pass a "flag" (a boolean true/false parameter) to a PowerShell script. For instance, your script may accept a "force" where the script runs in a more careful mode when force is not used.

The keyword for that is [switch] parameter type:

 param (
    [string]$server = "http://defaultserver",
    [string]$password = $( Read-Host "Input password, please" ),
    [switch]$force = $false
 )

Inside the script then you would work with it like this:

if ($force) {
  //deletes a file or does something "bad"
}

Now, when calling the script you'd set the switch/flag parameter like this:

.\yourscript.ps1 -server "http://otherserver" -force

If you explicitly want to state that the flag is not set, there is a special syntax for that

.\yourscript.ps1 -server "http://otherserver" -force:$false

Links to relevant Microsoft documentation (for PowerShell 5.0; tho versions 3.0 and 4.0 are also available at the links):

• about_Scripts
• about_Functions
• about_Functions_Advanced_Parameters

Solution provide in the questions which you linked is correct. Problem with your implementation is that You have not specified the ID of element correctly.

Secondly you need to use load event to execute your code. Currently DOM is not loaded hence element is not found thus you are getting error.

HTML

<div id="YourElementId" ng-app='MyModule' ng-controller="MyController">
    Hi
</div>

JS Code

angular.module('MyModule', [])
    .controller('MyController', function ($scope) {
    $scope.myfunction = function (data) {
        alert("---" + data);
    };
});

window.onload = function () {
    angular.element(document.getElementById('YourElementId')).scope().myfunction('test');
}

An easy solution for most situations: copy/paste the markdown into a viewer in the "cloud." Here are two choices:

1. Dillinger.io
2. Dingus

Nothing to install! Cross platform! Cross browser! Always available!

Disadvantages: could be hassle for large files, standard cloud application security issues.

At least with Active Directory, I have been able to search by DistinguishedName by doing an LDAP query in this format (assuming that such a record exists with this distinguishedName):

"(distinguishedName=CN=Dev-India,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com)"

No, Google Chrome does not work with Selenium IDE. As Selenium IDE is a Firefox plugin it works only with FF.

According to your last portion of question: Or is there any alternative tool which can work with Chrome? The possible answer is as follows:

You can use Sahi with Chrome. Sahi Test Automation tool supports Chrome, Firefox and IE. You can visit for details:

http://sahi.co.in/

There is an alternative solution, use Chrome-Developer-Mode-Extension-Warning-Patcher:

1. Download the latest release from here from Github.
2. Close Chrome.
3. Unpack the zip archive and run ChromeDevExtWarningPatcher.exe as administrator.
4. Select your Chrome installation from the just opened GUI and then click on Patch button:

5. Enjoy Chrome without any DevMode pop-up!

I've used MongoDB extensively (for the past 6 months), building a hierarchical data management system, and I can vouch for both the ease of setup (install it, run it, use it!) and the speed. As long as you think about indexes carefully, it can absolutely scream along, speed-wise.

I gather that Cassandra, due to its use with large-scale projects like Twitter, has better scaling functionality, although the MongoDB team is working on parity there. I should point out that I've not used Cassandra beyond the trial-run stage, so I can't speak for the detail.

The real swinger for me, when we were assessing NoSQL databases, was the querying - Cassandra is basically just a giant key/value store, and querying is a bit fiddly (at least compared to MongoDB), so for performance you'd have to duplicate quite a lot of data as a sort of manual index. MongoDB, on the other hand, uses a "query by example" model.

For example, say you've got a Collection (MongoDB parlance for the equivalent to a RDMS table) containing Users. MongoDB stores records as Documents, which are basically binary JSON objects. e.g:

{
   FirstName: "John",
   LastName: "Smith",
   Email: "[email protected]",
   Groups: ["Admin", "User", "SuperUser"]
}

If you wanted to find all of the users called Smith who have Admin rights, you'd just create a new document (at the admin console using Javascript, or in production using the language of your choice):

{
   LastName: "Smith",
   Groups: "Admin"
}

...and then run the query. That's it. There are added operators for comparisons, RegEx filtering etc, but it's all pretty simple, and the Wiki-based documentation is pretty good.

the documentations refers to an ASP.NET application.
You can try and have a look at my answer here.
I have an example attached to my reply.
Another example for ASP.NET MVC3 can be found here.

if the type is list, use len(list) and len(list[0]) to get the row and column.

l = [[1,2,3,4], [0,1,3,4]]

len(l) will be 2 len(l[0]) will be 4

Adding to Rob?'s answer: in case you want to print rather large numbers, using thousand separators can be a great help (note the comma).

>>> f'{a*1000:,.2f}'
'10,123.40'

Easiest way to solve this problem with the focus function of JavaScript as follows:

You can copy and try it @ home!

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <title></title>
  </head>
  <body>

    <input id="input1" type="text" onkeypress="pressEnter()" />
    <input id="input2" type="text" onkeypress="pressEnter2()" />
    <input id="input3" type="text"/>

    <script type="text/javascript">
    function pressEnter() {
      // Key Code for ENTER = 13
      if ((event.keyCode == 13)) {
        document.getElementById("input2").focus({preventScroll:false});
      }
    }
    function pressEnter2() {
      if ((event.keyCode == 13)) {
        document.getElementById("input3").focus({preventScroll:false});
      }
    }
    </script>

  </body>
</html>

I came here because I was trying to use ifconfig on the container to find its IPAaddress and there was no ifconfig. If you really need ifconfig on the container go with @vishnu-narayanan answer above, however you may be able to get the information you need by using docker inspect on the host:

docker inspect <containerid>

There is lots of good stuff in the output including IPAddress of container:

"Networks": {
    "bridge": {
        "IPAMConfig": null,
        "Links": null,
        "Aliases": null,
        "NetworkID": "12345FAKEID",
        "EndpointID": "12345FAKEENDPOINTID",
        "Gateway": "172.17.0.1",
        "IPAddress": "172.17.0.3",
        "IPPrefixLen": 16,
        "IPv6Gateway": "",
        "GlobalIPv6Address": "",
        "GlobalIPv6PrefixLen": 0,
        "MacAddress": "01:02:03:04:05:06",
        "DriverOpts": null
    }
}

Use Uri class and use Host property

Uri url = new Uri(@"http://support.domain.com/default.aspx?id=12345");
Console.WriteLine(url.Host);

if you just need to get a key-value from a simple dictionary like e.g:

os_type = {'ubuntu': '20.04'}

use popitem() method:

os, version = os_type.popitem()
print(os) # 'ubuntu'
print(version) # '20.04'

++ This worked for me. It's vanilla javascirpt and good for use cases such as de-cluttering when testing with ngMocks library:

<!-- specRunner.html - keep this at the top of your <script> asset loading so that it is available readily -->
<!--  Frienly tip - have all JSON files in a json-data folder for keeping things organized-->
<script src="json-data/findByIdResults.js" charset="utf-8"></script>
<script src="json-data/movieResults.js" charset="utf-8"></script>

This is your javascript file that contains the JSON data

// json-data/JSONFindByIdResults.js
var JSONFindByIdResults = {
     "Title": "Star Wars",
     "Year": "1983",
     "Rated": "N/A",
     "Released": "01 May 1983",
     "Runtime": "N/A",
     "Genre": "Action, Adventure, Sci-Fi",
     "Director": "N/A",
     "Writer": "N/A",
     "Actors": "Harrison Ford, Alec Guinness, Mark Hamill, James Earl Jones",
     "Plot": "N/A",
     "Language": "English",
     "Country": "USA",
     "Awards": "N/A",
     "Poster": "N/A",
     "Metascore": "N/A",
     "imdbRating": "7.9",
     "imdbVotes": "342",
     "imdbID": "tt0251413",
     "Type": "game",
     "Response": "True"
};

Finally, work with the JSON data anywhere in your code

// working with JSON data in code
var findByIdResults = window.JSONFindByIdResults;

Note:- This is great for testing and even karma.conf.js accepts these files for running tests as seen below. Also, I recommend this only for de-cluttering data and testing/development environment.

// extract from karma.conf.js
files: [
     'json-data/JSONSearchResultHardcodedData.js',
     'json-data/JSONFindByIdResults.js'
     ...
]

Hope this helps.

UPDATE

An easier way that worked for me is just include a function at the bottom of the code returning whatever JSON.

// within test code
let movies = getMovieSearchJSON();
.....
...
...
....
// way down below in the code
function getMovieSearchJSON() {
      return {
         "Title": "Bri Squared",
         "Year": "2011",
         "Rated": "N/A",

         "Runtime": "N/A",
         "Genre": "Comedy",
         "Director": "Joy Gohring",
         "Writer": "Briana Lane",
         "Actors": "Brianne Davis, Briana Lane, Jorge Garcia, Gabriel Tigerman",
         "Plot": "N/A",
         "Language": "English",
         "Country": "USA",
         "Awards": "N/A",
         "Poster": "http://ia.media-imdb.com/images/M/MV5BMjEzNDUxMDI4OV5BMl5BanBnXkFtZTcwMjE2MzczNQ@@._V1_SX300.jpg",

         "Response": "True"
   }
}

HashMap<String, List<Integer>> map = new HashMap<String, List<Integer>>();
HashMap<String, int[]> map = new HashMap<String, int[]>();

pick one, for example

HashMap<String, List<Integer>> map = new HashMap<String, List<Integer>>();
map.put("Something", new ArrayList<Integer>());
for (int i=0;i<numarulDeCopii; i++) {
    map.get("Something").add(coeficientUzura[i]); 
}

or just

HashMap<String, int[]> map = new HashMap<String, int[]>();
map.put("Something", coeficientUzura);

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

Here is another idea that allow you to affect other elements without considering any specific selector and by only using the :hover state of the main element.

For this, I will rely on the use of custom properties (CSS variables). As we can read in the specification:

Custom properties are ordinary properties, so they can be declared on any element, are resolved with the normal inheritance and cascade rules ...

The idea is to define custom properties within the main element and use them to style child elements and since these properties are inherited we simply need to change them within the main element on hover.

Here is an example:

#container {_x000D_
  width: 200px;_x000D_
  height: 30px;_x000D_
  border: 1px solid var(--c);_x000D_
  --c:red;_x000D_
}_x000D_
#container:hover {_x000D_
  --c:blue;_x000D_
}_x000D_
#container > div {_x000D_
  width: 30px;_x000D_
  height: 100%;_x000D_
  background-color: var(--c);_x000D_
}

<div id="container">_x000D_
  <div>_x000D_
  </div>_x000D_
</div>

Why this can be better than using specific selector combined with hover?

I can provide at least 2 reasons that make this method a good one to consider:

1. If we have many nested elements that share the same styles, this will avoid us complex selector to target all of them on hover. Using Custom properties, we simply change the value when hovering on the parent element.
2. A custom property can be used to replace a value of any property and also a partial value of it. For example we can define a custom property for a color and we use it within a border, linear-gradient, background-color, box-shadow etc. This will avoid us reseting all these properties on hover.

Here is a more complex example:

.container {_x000D_
  --c:red;_x000D_
  width:400px;_x000D_
  display:flex;_x000D_
  border:1px solid var(--c);_x000D_
  justify-content:space-between;_x000D_
  padding:5px;_x000D_
  background:linear-gradient(var(--c),var(--c)) 0 50%/100% 3px no-repeat;_x000D_
}_x000D_
.box {_x000D_
  width:30%;_x000D_
  background:var(--c);_x000D_
  box-shadow:0px 0px 5px var(--c);_x000D_
  position:relative;_x000D_
}_x000D_
.box:before {_x000D_
  content:"A";_x000D_

As we can see above, we only need one CSS declaration in order to change many properties of different elements.

Which version of JUnit is this? I've only ever seen delta, not epsilon - but that's a side issue!

From the JUnit javadoc:

delta - the maximum delta between expected and actual for which both numbers are still considered equal.

It's probably overkill, but I typically use a really small number, e.g.

private static final double DELTA = 1e-15;

@Test
public void testDelta(){
    assertEquals(123.456, 123.456, DELTA);
}

If you're using hamcrest assertions, you can just use the standard equalTo() with two doubles (it doesn't use a delta). However if you want a delta, you can just use closeTo() (see javadoc), e.g.

private static final double DELTA = 1e-15;

@Test
public void testDelta(){
    assertThat(123.456, equalTo(123.456));
    assertThat(123.456, closeTo(123.456, DELTA));
}

FYI the upcoming JUnit 5 will also make delta optional when calling assertEquals() with two doubles. The implementation (if you're interested) is:

private static boolean doublesAreEqual(double value1, double value2) {
    return Double.doubleToLongBits(value1) == Double.doubleToLongBits(value2);
}

you can set an image URL for the content prop instead of the background-image.

content: url(/img/border-left3.png);

I use the filter solution above, for ie8. However.. In order to solve the freezing links problem , do also the following:

background: no-repeat center center fixed\0/; /* IE8 HACK */

This has solved the frozen links problem for me.

you can use default ng-submitted is set if the form was submitted.

https://docs.angularjs.org/api/ng/directive/form

example: http://jsbin.com/cowufugusu/1/

1. Use ref attribute on DOM element for reference

<div class="content scrollable" ref="msgContainer">
    <!-- content -->
</div>

2. You need to setup a WATCH

  data() {
    return {
      count: 5
    };
  },
  watch: {
    count: function() {
      this.$nextTick(function() {
        var container = this.$refs.msgContainer;
        container.scrollTop = container.scrollHeight + 120;
      });
    }
  }

3. Ensure you're using proper CSS

.scrollable {
  overflow: hidden;
  overflow-y: scroll;
  height: calc(100vh - 20px);
}

Or, in order to avoid modifying slowFunc (say you don't have access to the source code for instance):

var source = new CancellationTokenSource(); //original code
source.Token.Register(CancelNotification); //original code
source.CancelAfter(TimeSpan.FromSeconds(1)); //original code
var completionSource = new TaskCompletionSource<object>(); //New code
source.Token.Register(() => completionSource.TrySetCanceled()); //New code
var task = Task<int>.Factory.StartNew(() => slowFunc(1, 2), source.Token); //original code

//original code: await task;  
await Task.WhenAny(task, completionSource.Task); //New code

You can also use nice extension methods from https://github.com/StephenCleary/AsyncEx and have it looks as simple as:

await Task.WhenAny(task, source.Token.AsTask());

You can always use a hidden div and use javascript to "popup" the div and have buttons that are like yes and or no. Pretty easy stuff to do.

May be with:

SELECT count(*) FROM `table` 
where 
    created_at>='2011-03-17 06:42:10' and created_at<='2011-03-17 07:42:50';

or use between:

SELECT count(*) FROM `table` 
where 
    created_at between '2011-03-17 06:42:10' and '2011-03-17 07:42:50';

You can change the datetime as per your need. May be use curdate() or now() to get the desired dates.

This website contains a much cleaner solution, it leaves pip intact as-well and one can easily switch between 3.5 and 3.6 and then whenever 3.7 is released.

http://ubuntuhandbook.org/index.php/2017/07/install-python-3-6-1-in-ubuntu-16-04-lts/

A short summary:

sudo apt-get install python python-pip python3 python3-pip
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

Then

$ pip -V
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.5/dist-packages (python 3.5)

Then to select python 3.6 run

sudo update-alternatives --config python3

and select '2'. Then

$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

To update pip select the desired version and

pip3 install --upgrade pip

$ pip3 -V
pip 9.0.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

Tested on Ubuntu 16.04.

select * 
from tempdb.INFORMATION_SCHEMA.COLUMNS 
where TABLE_NAME=OBJECT_NAME(OBJECT_ID('#table'))

SQL Server DateDiff

DECLARE @startdate datetime2 = '2007-05-05 12:10:09.3312722';
DECLARE @enddate datetime2 = '2009-05-04 12:10:09.3312722'; 
SELECT DATEDIFF(day, @startdate, @enddate);

It's usually \t in command-line interfaces, which will convert the char \t into the whitespace tab character.

For example, hello\talex -> hello--->alex.

For tomcat you can increase the permGem space by using

 -XX:MaxPermSize=128m

For this you need to create (if not already exists) a file named setenv.sh in tomcat/bin folder and include following line in it

   export JAVA_OPTS="-XX:MaxPermSize=128m"

As explained on another answer using pandas.DataFrame() directly here will not act as you think.

What you can do is use pandas.DataFrame.from_dict with orient='index':

In[7]: pandas.DataFrame.from_dict({u'2012-06-08': 388,
 u'2012-06-09': 388,
 u'2012-06-10': 388,
 u'2012-06-11': 389,
 u'2012-06-12': 389,
 .....
 u'2012-07-05': 392,
 u'2012-07-06': 392}, orient='index', columns=['foo'])
Out[7]: 
            foo
2012-06-08  388
2012-06-09  388
2012-06-10  388
2012-06-11  389
2012-06-12  389
........
2012-07-05  392
2012-07-06  392

To stop executing java code just use this command:

    System.exit(1);

After this command java stops immediately!

for example:

    int i = 5;
    if (i == 5) {
       System.out.println("All is fine...java programm executes without problem");
    } else {
       System.out.println("ERROR occured :::: java programm has stopped!!!");
       System.exit(1);
    }

stack size can indeed be unlimited. _STK_LIM is the default, _STK_LIM_MAX is something that differs per architecture, as can be seen from include/asm-generic/resource.h:

/*
 * RLIMIT_STACK default maximum - some architectures override it:
 */
#ifndef _STK_LIM_MAX
# define _STK_LIM_MAX           RLIM_INFINITY
#endif

As can be seen from this example generic value is infinite, where RLIM_INFINITY is, again, in generic case defined as:

/*
 * SuS says limits have to be unsigned.
 * Which makes a ton more sense anyway.
 *
 * Some architectures override this (for compatibility reasons):
 */
#ifndef RLIM_INFINITY
# define RLIM_INFINITY          (~0UL)
#endif

So I guess the real answer is - stack size CAN be limited by some architecture, then unlimited stack trace will mean whatever _STK_LIM_MAX is defined to, and in case it's infinity - it is infinite. For details on what it means to set it to infinite and what implications it might have, refer to the other answer, it's way better than mine.

Using application/x-www-form-urlencoded format in axios

By default, axios serializes JavaScript objects to JSON. To send data in the application/x-www-form-urlencoded format instead, you can use one of the following options.

Browser

In a browser, you can use the URLSearchParams API as follows:

const params = new URLSearchParams();

params.append('param1', 'value1');

params.append('param2', 'value2');

axios.post('/foo', params);

Note that URLSearchParams is not supported by all browsers (see caniuse.com), but there is a polyfill available (make sure to polyfill the global environment).

Alternatively, you can encode data using the qs library:

const qs = require('qs');

axios.post('/foo', qs.stringify({ 'bar': 123 }));

Or in another way (ES6),

import qs from 'qs';

const data = { 'bar': 123 };

const options = {

method: 'POST',

headers: { 'content-type': 'application/x-www-form-urlencoded' },

data: qs.stringify(data),

url, };

axios(options);

Change

 mAdapter = new RecordingsListAdapter(this, recordings);

to

 mAdapter = new RecordingsListAdapter(getActivity(), recordings);

and also make sure that recordings!=null at mAdapter = new RecordingsListAdapter(this, recordings);

Take a look at this this post from android-developers, that might help increasing the security on the stored data in your Android app.

Using Cryptography to Store Credentials Safely

You can try this:

function Get-UrlStatusCode([string] $Url)
{
    try
    {
        (Invoke-WebRequest -Uri $Url -UseBasicParsing -DisableKeepAlive).StatusCode
    }
    catch [Net.WebException]
    {
        [int]$_.Exception.Response.StatusCode
    }
}

$statusCode = Get-UrlStatusCode 'httpstat.us/500'

take look at this sample code from my project

public static IList<Letter> GetDepartmentLettersLinq(int departmentId)
{
    IEnumerable<Letter> allDepartmentLetters =
        from allLetter in LetterService.GetAllLetters()
        join allUser in UserService.GetAllUsers() on allLetter.EmployeeID equals allUser.ID into usersGroup
        from user in usersGroup.DefaultIfEmpty()// here is the tricky part
        join allDepartment in DepartmentService.GetAllDepartments() on user.DepartmentID equals allDepartment.ID
        where allDepartment.ID == departmentId
        select allLetter;

    return allDepartmentLetters.ToArray();
}

in this code I joined 3 tables and I spited join condition from where clause

note: the Services classes are just warped(encapsulate) the database operations

WARNING: This tweak is not truly working as it turns out. Sorry for the inconvenience.

Original post below:

I found a solution while playing with Git internals!

1. Suppose you are in your repository.

2. Create your empty directory:

   $ mkdir path/to/empty-folder
   

3. Add it to the index using a plumbing command and the empty tree SHA-1:

   $ git update-index --index-info
   040000 tree 4b825dc642cb6eb9a060e54bf8d69288fbee4904    path/to/empty-folder
   

   Type the command and then enter the second line. Press Enter and then Ctrl + D to terminate your input. Note: the format is mode [SPACE] type [SPACE] SHA-1hash [TAB] path (the tab is important, the answer formatting does not preserve it).

4. That's it! Your empty folder is in your index. All you have to do is commit.

This solution is short and apparently works fine (see the EDIT!), but it is not that easy to remember...

The empty tree SHA-1 can be found by creating a new empty Git repository, cd into it and issue git write-tree, which outputs the empty tree SHA-1.

EDIT:

I've been using this solution since I found it. It appears to work exactly the same way as creating a submodule, except that no module is defined anywhere. This leads to errors when issuing git submodule init|update. The problem is that git update-index rewrites the 040000 tree part into 160000 commit.

Moreover, any file placed under that path won't ever be noticed by Git, as it thinks they belong to some other repository. This is nasty as it can easily be overlooked!

However, if you don't already (and won't) use any Git submodules in your repository, and the "empty" folder will remain empty or if you want Git to know of its existence and ignore its content, you can go with this tweak. Going the usual way with submodules takes more steps that this tweak.

Remove the index and do reset

rm -f .git/index
git reset

As far as the Markdown syntax is concerned, if you want to get that detailed, you'll just have to use HTML.

<a href="http://example.com/" target="_blank">Hello, world!</a>

Most Markdown engines I've seen allow plain old HTML, just for situations like this where a generic text markup system just won't cut it. (The StackOverflow engine, for example.) They then run the entire output through an HTML whitelist filter, regardless, since even a Markdown-only document can easily contain XSS attacks. As such, if you or your users want to create _blank links, then they probably still can.

If that's a feature you're going to be using often, it might make sense to create your own syntax, but it's generally not a vital feature. If I want to launch that link in a new window, I'll ctrl-click it myself, thanks.

dynamically allocate some memory using new:

int* array = new int[SIZE];

There is an overload with 3 arguments. Html.DropdownList(name, selectList, optionLabel) Update: there was a typo in the below code snippet.

@Html.DropDownList("Cat", new SelectList(ViewBag.Categories,"ID", "CategoryName"), "-Select Category-")

For the validator use

@Html.ValidationMessage("Cat")

If it's jQuery...

$("#myText").val('');

or

document.getElementById('myText').value = '';

Hidden layers are used in accordance with the complexity of our data. If we have input data which is linearly separable then we need not to use hidden layer e.g. OR gate but if we have a non linearly seperable data then we need to use hidden layer for example ExOR logical gate. Number of nodes taken at any layer depends upon the degree of cross validation of our output.

            console.log("arr ", arr)
            var dataNueva = []

            arr.forEach(data => {
                console.log("data renaes ", data)
            })
            // this.setState({ DataEESSsend: dataNueva })
            console.log("dataNueva ", dataNueva)

        };


        if (rABS) reader.readAsBinaryString(file);
        else reader.readAsArrayBuffer(file);

    handleChange = e => {
        const files = e.target.files;
        if (files && files[0]) {
            this.handleFile(files[0]);
        }
    };

Likewise, here's a 2nd caveat to @Artif3x elaboration of @max-malysh's excellent answer, both above.

With any delayed application of transactions from the master the follower(s) will have an older, stale view of the data. Therefore while providing time for the query on the follower to finish by setting max_standby_archive_delay and max_standby_streaming_delay makes sense, keep both of these caveats in mind:

• the value of the follower as a standby / backup diminishes
• any other queries running on the follower may return stale data.

If the value of the follower for backup ends up being too much in conflict with hosting queries, one solution would be multiple followers, each optimized for one or the other.

Also, note that several queries in a row can cause the application of wal entries to keep being delayed. So when choosing the new values, it’s not just the time for a single query, but a moving window that starts whenever a conflicting query starts, and ends when the wal entry is finally applied.

Your Fragment can subclass ListFragment.
And onCreateView() from ListFragment will return a ListView you can then populate.

If you have initialized the form like this

form = CustomForm()

then the correct way as of Jan 2019, is to use .initial to replace the data. This will replace the data in the intial dict that goes along with the form. It also works if you have initialized using some instance such as form = CustomForm(instance=instance)

To replace data in the form, you need to

form.initial['Email'] = GetEmailString()

Generalizing this it would be,

form.initial['field_name'] = new_value

I don't belive there's a way to do it within one query, but you can play tricks like this with a temporary variable:

declare @s varchar(max)
set @s = ''
select @s = @s + City + ',' from Locations

select @s

It's definitely less code than walking over a cursor, and probably more efficient.

The workaround I used was a LifeCycleCallback. Still waiting to see if there is any more "native" method, for instance @Column(type="string", default="hello default value").

/**
 * @Entity @Table(name="posts") @HasLifeCycleCallbacks
 */
class Post implements Node, \Zend_Acl_Resource_Interface {

...

/**
 * @PrePersist
 */
function onPrePersist() {
    // set default date
    $this->dtPosted = date('Y-m-d H:m:s');
}

You need to checkout the branch:

git checkout master

See the Git cheat sheets for more information.

Edit: Please note that git does not manage empty directories, so you'll have to manage them yourself. If your directory is empty, just remove it directly.

This SP looks very strange. It does not modify what is passed to @b. And nowhere in the SP you assign anything to @b. And @Password is not defined, so this SP will not work at all.

I would guess you actually want to return @Password, or to have SET @b = (SELECT...)

Much simpler will be if you modify your SP to (note, no OUTPUT parameter):

set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go

ALTER PROCEDURE [dbo].[Validate] @a varchar(50)

AS

SELECT TOP 1 Password FROM dbo.tblUser WHERE Login = @a

Then, your code can use cmd.ExecuteScalar, and receive the result.

If you are add more than argument ya dropdownlist in Asp.Net MVC. When you Edit record or pass value in view bag.

Use this it will be work:-

@Html.DropDownList("CurrencyID",null,String.Empty, new { @class = "form-control-mandatory" })

As I understand , all of previous answers , does not make an Array output, In my case : I have a model with parent-children structure (simplified code here):

public function parent(){

    return $this->belongsTo('App\Models\Accounting\accounting_coding', 'parent_id');
}


public function children()
{

    return $this->hasMany('App\Models\Accounting\accounting_coding', 'parent_id');
}

and if you want to have all of children IDs as an Array , This approach is fine and working for me :

public function allChildren()
{
    $allChildren = [];
    if ($this->has_branch) {

        foreach ($this->children as $child) {

            $subChildren = $child->allChildren();

            if (count($subChildren) == 1) {
                $allChildren  [] = $subChildren[0];
            } else if (count($subChildren) > 1) {
                $allChildren += $subChildren;
            }
        }
    }
    $allChildren  [] = $this->id;//adds self Id to children Id list

    return $allChildren; 
}

the allChildren() returns , all of childrens as a simple Array .

Are you sure the odbc connector is well created ? if not check the step "Create an ODBC Connection" again

EDIT: Connection without DSN from php.net

// Microsoft Access

$connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=$mdbFilename", $user, $password);

in your case it might be if your filename is northwind and your file extension mdb:

$connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=northwind", "", "");

Well then: welcome to the R world ;-)

Here you go

Setting up the code

urls <- c(
    "http://stat.ethz.ch/R-manual/R-devel/library/base/html/connections.html",
    "http://en.wikipedia.org/wiki/Xz",
    "xxxxx"
)
readUrl <- function(url) {
    out <- tryCatch(
        {
            # Just to highlight: if you want to use more than one 
            # R expression in the "try" part then you'll have to 
            # use curly brackets.
            # 'tryCatch()' will return the last evaluated expression 
            # in case the "try" part was completed successfully

            message("This is the 'try' part")

            readLines(con=url, warn=FALSE) 
            # The return value of `readLines()` is the actual value 
            # that will be returned in case there is no condition 
            # (e.g. warning or error). 
            # You don't need to state the return value via `return()` as code 
            # in the "try" part is not wrapped inside a function (unlike that
            # for the condition handlers for warnings and error below)
        },
        error=function(cond) {
            message(paste("URL does not seem to exist:", url))
            message("Here's the original error message:")
            message(cond)
            # Choose a return value in case of error
            return(NA)
        },
        warning=function(cond) {
            message(paste("URL caused a warning:", url))
            message("Here's the original warning message:")
            message(cond)
            # Choose a return value in case of warning
            return(NULL)
        },
        finally={
        # NOTE:
        # Here goes everything that should be executed at the end,
        # regardless of success or error.
        # If you want more than one expression to be executed, then you 
        # need to wrap them in curly brackets ({...}); otherwise you could
        # just have written 'finally=<expression>' 
            message(paste("Processed URL:", url))
            message("Some other message at the end")
        }
    )    
    return(out)
}

Applying the code

> y <- lapply(urls, readUrl)
Processed URL: http://stat.ethz.ch/R-manual/R-devel/library/base/html/connections.html
Some other message at the end
Processed URL: http://en.wikipedia.org/wiki/Xz
Some other message at the end
URL does not seem to exist: xxxxx
Here's the original error message:

Processed URL: xxxxx
Some other message at the end
Warning message:

Additional remarks

tryCatch

tryCatch returns the value associated to executing expr unless there's an error or a warning. In this case, specific return values (see return(NA) above) can be specified by supplying a respective handler function (see arguments error and warning in ?tryCatch). These can be functions that already exist, but you can also define them within tryCatch() (as I did above).

The implications of choosing specific return values of the handler functions

As we've specified that NA should be returned in case of error, the third element in y is NA. If we'd have chosen NULL to be the return value, the length of y would just have been 2 instead of 3 as lapply() will simply "ignore" return values that are NULL. Also note that if you don't specify an explicit return value via return(), the handler functions will return NULL (i.e. in case of an error or a warning condition).

"Undesired" warning message

As warn=FALSE doesn't seem to have any effect, an alternative way to suppress the warning (which in this case isn't really of interest) is to use

suppressWarnings(readLines(con=url))

instead of

readLines(con=url, warn=FALSE)

Multiple expressions

Note that you can also place multiple expressions in the "actual expressions part" (argument expr of tryCatch()) if you wrap them in curly brackets (just like I illustrated in the finally part).

Here is how to do this as of Typescript 2.0: (tsd and typings are being deprecated in favor of the following):

$ npm install --save lodash

# This is the new bit here: 
$ npm install --save-dev @types/lodash

Then, in your .ts file:

Either:

import * as _ from "lodash";

Or (as suggested by @Naitik):

import _ from "lodash";

I'm not positive what the difference is. We use and prefer the first syntax. However, some report that the first syntax doesn't work for them, and someone else has commented that the latter syntax is incompatible with lazy loaded webpack modules. YMMV.

Edit on Feb 27th, 2017:

According to @Koert below, import * as _ from "lodash"; is the only working syntax as of Typescript 2.2.1, lodash 4.17.4, and @types/lodash 4.14.53. He says that the other suggested import syntax gives the error "has no default export".

The wording of your question is odd - Abstraction vs Encapsulation? It should be - someone explain abstraction and encapsulation...

Abstraction is understanding the essence of the thing.

A real world example is abstract art. The artists of this style try to capture/paint the essence of the thing that still allows it to be the thing. This brown smear of 4 lines captures the essence of what a bull is.

Encapsulation is black boxing.

A cell phone is a great example. I have no idea how the cell phone connects to a satellite, tower, or another phone. I have no idea how the damn thing understands my key presses or how it takes and sends pictures to an email address or another phone number. I have no idea about the intricate details of most of how a modern smart phone works. But, I can use it! The phones have standard interfaces (yes - both literal and software design) that allows someone who understand the basics of one to use almost all of them.

How are the two related?

Both abstraction and encapsulation are underlying foundations of object oriented thought and design. So, in our cell phone example. The notion of a smart phone is an abstraction, within which certain features and services are encapsulated. The iPhone and Galaxy are further abstractions of the higher level abstraction. Your physical iPhone or Galaxy are concrete examples of multiple layers of abstractions which contain encapsulated features and services.

A small update to this one:

if you use the following it will update on the fly rather than on mouse release.

"change mousemove", function"

<script>
$('input[type="range"]').on("change mousemove", function () {
    var val = ($(this).val() - $(this).attr('min')) / ($(this).attr('max') - $(this).attr('min'));

    $(this).css('background-image',
                '-webkit-gradient(linear, left top, right top, '
                + 'color-stop(' + val + ', #2f466b), '
                + 'color-stop(' + val + ', #d3d3db)'
                + ')'
                );
});</script>

Note: I will elaborate more my answer for Python 3 since the end of life of Python 2 is very close.

In Python 3

bytes consists of sequences of 8-bit unsigned values, while str consists of sequences of Unicode code points that represent textual characters from human languages.

>>> # bytes
>>> b = b'h\x65llo'
>>> type(b)
<class 'bytes'>
>>> list(b)
[104, 101, 108, 108, 111]
>>> print(b)
b'hello'
>>>
>>> # str
>>> s = 'nai\u0308ve'
>>> type(s)
<class 'str'>
>>> list(s)
['n', 'a', 'i', '¨', 'v', 'e']
>>> print(s)
nai¨ve

Even though bytes and str seem to work the same way, their instances are not compatible with each other, i.e, bytes and str instances can't be used together with operators like > and +. In addition, keep in mind that comparing bytes and str instances for equality, i.e. using ==, will always evaluate to False even when they contain exactly the same characters.

>>> # concatenation
>>> b'hi' + b'bye' # this is possible
b'hibye'
>>> 'hi' + 'bye' # this is also possible
'hibye'
>>> b'hi' + 'bye' # this will fail
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: can't concat str to bytes
>>> 'hi' + b'bye' # this will also fail
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: can only concatenate str (not "bytes") to str
>>>
>>> # comparison
>>> b'red' > b'blue' # this is possible
True
>>> 'red'> 'blue' # this is also possible
True
>>> b'red' > 'blue' # you can't compare bytes with str
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: '>' not supported between instances of 'bytes' and 'str'
>>> 'red' > b'blue' # you can't compare str with bytes
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: '>' not supported between instances of 'str' and 'bytes'
>>> b'blue' == 'red' # equality between str and bytes always evaluates to False
False
>>> b'blue' == 'blue' # equality between str and bytes always evaluates to False
False

Another issue when dealing with bytes and str is present when working with files that are returned using the open built-in function. On one hand, if you want ot read or write binary data to/from a file, always open the file using a binary mode like 'rb' or 'wb'. On the other hand, if you want to read or write Unicode data to/from a file, be aware of the default encoding of your computer, so if necessary pass the encoding parameter to avoid surprises.

In Python 2

str consists of sequences of 8-bit values, while unicode consists of sequences of Unicode characters. One thing to keep in mind is that str and unicode can be used together with operators if str only consists of 7-bit ASCI characters.

It might be useful to use helper functions to convert between str and unicode in Python 2, and between bytes and str in Python 3.

More general sorted, where the key keyword defines the sorting method, minus before numerical type indicates descending:

>>> x = Counter({'a':5, 'b':3, 'c':7})
>>> sorted(x.items(), key=lambda k: -k[1])  # Ascending
[('c', 7), ('a', 5), ('b', 3)]

If you have a github account and don't want to download software, you can export to github, then download a zip from github.

Another trap of note is making sure you're not decorating controllers with the Consume Attribute as below:

[Produces("application/json")]
[Consumes("application/json")]
public class MyController : Controller

This will fail with a 415 Unsupported Media Type if the upload is NOT JSON.

A "friend of mine" was recently caught out by this like so:

public class MyFileUploadController : MyCustomController {

}

[Produces("application/json")]
[Consumes("application/json")]
public class MyCustomController : ControllerBase {

}

Converting the date to the first of the month allows you to Group By and Order By a single attribute, and it's faster in my experience.

declare @mytable table(mydate datetime)
declare @date datetime
set @date = '19000101'
while @date < getdate() begin
    insert into @mytable values(@date)
    set @date = dateadd(day,1,@date)
end

select count(*) total_records from @mytable

select dateadd(month,datediff(month,0,mydate),0) first_of_the_month, count(*) cnt
from @mytable
group by dateadd(month,datediff(month,0,mydate),0)

Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.

In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.

Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.

It's 2021... keep it simple.

Times have changed and now the cleanest and most readable way to do this is:

Array.from(document.querySelectorAll('widget hover')).forEach((el) => el.classList.remove('hover'));

If you can't support arrow functions then just convert it like this:

Array.from(document.querySelectorAll('widget hover')).forEach(function(el) { 
    el.classList.remove('hover');
});

Additionally if you need to support extremely old browsers then use a polyfil for the forEach and Array.from and move on with your life.

I ended up figuring out a (pretty good) solution for this problem!

You can use a TransitionDrawable to accomplish this. For example, in an XML file in the drawable folder you could write something like:

<?xml version="1.0" encoding="UTF-8"?>
<transition xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- The drawables used here can be solid colors, gradients, shapes, images, etc. -->
    <item android:drawable="@drawable/original_state" />
    <item android:drawable="@drawable/new_state" />
</transition>

Then, in your XML for the actual View you would reference this TransitionDrawable in the android:background attribute.

At this point you can initiate the transition in your code on-command by doing:

TransitionDrawable transition = (TransitionDrawable) viewObj.getBackground();
transition.startTransition(transitionTime);

Or run the transition in reverse by calling:

transition.reverseTransition(transitionTime);

See Roman's answer for another solution using the Property Animation API, which wasn't available at the time this answer was originally posted.

I would perform a git clone via the command line (outside Eclipse) then use File -> Import... -> Existing Maven Projects.

Your projects will be understood as using Git and Maven. It's the fastest and most reliable way to import IMO.

You may use jQuery:

<input type="text" name="IP" id="IP" value=""/>
@Html.ActionLink(@Resource.ButtonTitleAdd, "Add", "Configure", new { ipValue ="xxx", TypeId = "1" }, new {@class = "link"})

<script>
  $(function () {
    $('.link').click(function () {
      var ipvalue = $("#IP").val();
      this.href = this.href.replace("xxx", ipvalue);
    });
  });
</script>

1. You can use Microsoft.Extensions.Configuration API with any .NET Core app, not only with ASP.NET Core app. Look into sample provided in the link, that shows how to read configs in the console app.

2. In most cases, the JSON source (read as .json file) is the most suitable config source.

   Note: don't be confused when someone says that config file should be appsettings.json. You can use any file name, that is suitable for you and file location may be different - there are no specific rules.

   But, as the real world is complicated, there are a lot of different configuration providers:

   • File formats (INI, JSON, and XML)
   • Command-line arguments
   • Environment variables

   and so on. You even could use/write a custom provider.

3. Actually, app.config configuration file was an XML file. So you can read settings from it using XML configuration provider (source on github, nuget link). But keep in mind, it will be used only as a configuration source - any logic how your app behaves should be implemented by you. Configuration Provider will not change 'settings' and set policies for your apps, but only read data from the file.

MSDeploy can migrate all content, config, etc. that is what the IIS team recommends. http://www.iis.net/extensions/WebDeploymentTool

To create a package, run the following command (replace Default Web Site with your web site name):

msdeploy.exe -verb:sync -source:apphostconfig="Default Web Site" -dest:package=c:\dws.zip > DWSpackage7.log

To restore the package, run the following command:

msdeploy.exe -verb:sync -source:package=c:\dws.zip -dest:apphostconfig="Default Web Site" > DWSpackage7.log

I was looking for this, and wrote a deep recursive one with indentation :

function objToString(obj, ndeep) {
  if(obj == null){ return String(obj); }
  switch(typeof obj){
    case "string": return '"'+obj+'"';
    case "function": return obj.name || obj.toString();
    case "object":
      var indent = Array(ndeep||1).join('\t'), isArray = Array.isArray(obj);
      return '{['[+isArray] + Object.keys(obj).map(function(key){
           return '\n\t' + indent + key + ': ' + objToString(obj[key], (ndeep||1)+1);
         }).join(',') + '\n' + indent + '}]'[+isArray];
    default: return obj.toString();
  }
}

Usage : objToString({ a: 1, b: { c: "test" } })

As long as you override equals() on each key and value contained in the map, then m1.equals(m2) should be reliable to check for maps equality.

The same result can be obtained also by comparing toString() of each map as you suggested, but using equals() is a more intuitive approach.

May not be your specific situation, but if you store arrays in the map, may be a little tricky, because they must be compared value by value, or using Arrays.equals(). More details about this see here.

During my current projects, I'm often passing rear parts of a path to a function and therefore use the Path module. To get the n-th part in reverse order, I'm using:

from typing import Union
from pathlib import Path

def get_single_subpath_part(base_dir: Union[Path, str], n:int) -> str:
    if n ==0:
        return Path(base_dir).name
    for _ in range(n):
        base_dir = Path(base_dir).parent
    return getattr(base_dir, "name")

path= "/folderA/folderB/folderC/folderD/"

# for getting the last part:
print(get_single_subpath_part(path, 0))
# yields "folderD"

# for the second last
print(get_single_subpath_part(path, 1))
#yields "folderC"

Furthermore, to pass the n-th part in reverse order of a path containing the remaining path, I use:

from typing import Union
from pathlib import Path

def get_n_last_subparts_path(base_dir: Union[Path, str], n:int) -> Path:
    return Path(*Path(base_dir).parts[-n-1:])

path= "/folderA/folderB/folderC/folderD/"

# for getting the last part:
print(get_n_last_subparts_path(path, 0))
# yields a `Path` object of "folderD"

# for second last and last part together 
print(get_n_last_subparts_path(path, 1))
# yields a `Path` object of "folderc/folderD"

Note that this function returns a Pathobject which can easily be converted to a string (e.g. str(path))

DateTime currentDateTime = DateTime.Now;
int week = (int) currentDateTime.DayOfWeek;

If only the field is required you could go with input:valid

#foo-thing:valid + .msg { visibility: visible!important; }      

 <input type="text" id="foo-thing" required="required">_x000D_
 <span class="msg" style="visibility: hidden;">Yay not empty</span>

See live on jsFiddle

OR negate using #foo-thing:invalid (credit to @SamGoody)

You can add new function to your jQuery library by adding these line on your own script file and you can easily use fadeSlideRight() and fadeSlideLeft().

Note: you can change width of animation as you like instance of 750px.

$.fn.fadeSlideRight = function(speed,fn) {
    return $(this).animate({
        'opacity' : 1,
        'width' : '750px'
    },speed || 400, function() {
        $.isFunction(fn) && fn.call(this);
    });
}

$.fn.fadeSlideLeft = function(speed,fn) {
    return $(this).animate({
        'opacity' : 0,
        'width' : '0px'
    },speed || 400,function() {
        $.isFunction(fn) && fn.call(this);
    });
}

The Array.find method support for Microsoft's browsers started with Edge.

The W3Schools compatibility table states that the support started on version 12, while the Can I Use compatibility table says that the support was unknown between version 12 and 14, being officially supported starting at version 15.

In Get:

public IActionResult Create()
{
    ViewData["Tags"] = new SelectList(_context.Tags, "Id", "Name");
    return View();
}

In Post:

var selectedIds= Request.Form["Tags"];

In View :

It's been a 5+ years for this question but heay always welcome to the efficient ways of coding/scripting.

var n = 123456789;
var arrayN = (`${n}`).split("").map(e => parseInt(e))

You don't need to change the delimiter to display the right part of the string with cut.

The -f switch of the cut command is the n-TH element separated by your delimiter : :, so you can just type :

 grep puddle2_1557936 | cut -d ":" -f2

Another solutions (adapt it a bit) if you want fun :

Using grep :

grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                        
/home/rogers.williams/folderz/puddle2

or still with look around regex

grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                    
/home/rogers.williams/folderz/puddle2

or with perl :

perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                      
/home/rogers.williams/folderz/puddle2

or using ruby (thanks to glenn jackman)

ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with awk :

awk -F'puddle2_1557936:' '{print $2}'  <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with python :

python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or using only bash :

IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2

or using js in a shell :

js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2

or using php in a shell :

php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2' 
/home/rogers.williams/folderz/puddle2

If I had to guess, you did this:

import datetime

at the top of your code. This means that you have to do this:

datetime.datetime.strptime(date, "%Y-%m-%d")

to access the strptime method. Or, you could change the import statement to this:

from datetime import datetime

and access it as you are.

The people who made the datetime module also named their class datetime:

#module  class    method
datetime.datetime.strptime(date, "%Y-%m-%d")

For this case word boundary (\b) can also be used instead of start anchor (^) and end anchor ($):

\b\d{1,45}\b

\b is a position between \w and \W (non-word char), or at the beginning or end of a string.

Note: Egg packaging has been superseded by Wheel packaging.

Same concept as a .jar file in Java, it is a .zip file with some metadata files renamed .egg, for distributing code as bundles.

Specifically: The Internal Structure of Python Eggs

A "Python egg" is a logical structure embodying the release of a specific version of a Python project, comprising its code, resources, and metadata. There are multiple formats that can be used to physically encode a Python egg, and others can be developed. However, a key principle of Python eggs is that they should be discoverable and importable. That is, it should be possible for a Python application to easily and efficiently find out what eggs are present on a system, and to ensure that the desired eggs' contents are importable.

The .egg format is well-suited to distribution and the easy uninstallation or upgrades of code, since the project is essentially self-contained within a single directory or file, unmingled with any other projects' code or resources. It also makes it possible to have multiple versions of a project simultaneously installed, such that individual programs can select the versions they wish to use.

pseudo-code:

minutes = floor(326.4/60)
seconds = round(326.4 - minutes * 60)

You can just loop though the items:

$("input[name^='card']").each(function() {
    console.log($(this).val());
});

There are multiple solutions for this. If you want the page to be refreshed you actually don't need JavaScript, the browser can do it for you if you add this meta tag in your head tag.

<meta http-equiv="refresh" content="30">

The browser will then refresh the page every 30 seconds.

If you really want to do it with JavaScript, then you can refresh the page every 30 seconds with location.reload() (docs) inside a setTimeout():

window.setTimeout(function () {
  window.location.reload();
}, 30000);

If you don't need to refresh the whole page but only a part of it, I guess an Ajax call would be the most efficient way.

var result = string.Join(",", arr);

This uses the following overload of string.Join:

public static string Join<T>(string separator, IEnumerable<T> values);

if (File.Exists(localUploadDirectory + "/" + fileName))
{                        
    `Your code here`
}

A nice solution that I've found is to do on UI something like:

<div *ngIf="vendorServicePricing && quantityPricing && service">
 ...Your page...
</div

Only when: vendorServicePricing, quantityPricing and service are loaded the page is rendered.

A lot of dancing around the answer. You can add the UDF context help, but you have to export the Module and edit the contents in a text editor, then re-import it to VBA. Here's the example from Chip Pearson: Adding Code Attributes

root:~/project#  -> root:~/project(dev)# 

add the following code to the end of your ~/.bashrc

force_color_prompt=yes
color_prompt=yes
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
if [ "$color_prompt" = yes ]; then
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[01;31m\]$(parse_git_branch)\[\033[00m\]\$ '
else
PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w$(parse_git_branch)\$ '
fi
unset color_prompt force_color_prompt

Try this, it was worked for me

.child {
    width: 100%;
    position: absolute;
    top: 0px;
    bottom: 0px;
    z-index: 1;
}

It will set child height to parent height

you can define a custom ScrollView class, & add an interface be called when scrolling like this:

public class ScrollChangeListenerScrollView extends HorizontalScrollView {


private MyScrollListener mMyScrollListener;

public ScrollChangeListenerScrollView(Context context) {
    super(context);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}


public void setOnMyScrollListener(MyScrollListener myScrollListener){
    this.mMyScrollListener = myScrollListener;
}


@Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
    super.onScrollChanged(l, t, oldl, oldt);
    if(mMyScrollListener!=null){
        mMyScrollListener.onScrollChange(this,l,t,oldl,oldt);
    }

}

public interface MyScrollListener {
    void onScrollChange(View view,int scrollX,int scrollY,int oldScrollX, int oldScrollY);
}

}

As of version 4.5 Microsoft changed the way it stores the .NET Framework indicator in the registry. There official guidance on how to retrieve the .NET framework and the CLR versions can be found here: https://msdn.microsoft.com/en-us/library/hh925568(v=vs.110).aspx

I am including modified version of their code to address the bounty question of how you determine the .NET framework for 4.5 and higher here:

using System;
using System.Reflection;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Win32;

namespace stackoverflowtesting
{
    class Program
    {
        static void Main(string[] args)
        {
            Dictionary<int, String> mappings = new Dictionary<int, string>();

            mappings[378389] = "4.5";
            mappings[378675] = "4.5.1 on Windows 8.1";
            mappings[378758] = "4.5.1 on Windows 8, Windows 7 SP1, and Vista";
            mappings[379893] = "4.5.2";
            mappings[393295] = "4.6 on Windows 10";
            mappings[393297] = "4.6 on Windows not 10";

            using (RegistryKey ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32).OpenSubKey("SOFTWARE\\Microsoft\\NET Framework Setup\\NDP\\v4\\Full\\"))
            {
                int releaseKey = Convert.ToInt32(ndpKey.GetValue("Release"));
                if (true)
                {
                    Console.WriteLine("Version: " + mappings[releaseKey]);
                }
            }
            int a = Console.Read();
        }
    }
}

Your thisdoesn't refer to the element in the step callback, instead you want to keep a reference to it at the beginning of your function (wrapped in $thisin my example):

$('.Count').each(function () {
  var $this = $(this);
  jQuery({ Counter: 0 }).animate({ Counter: $this.text() }, {
    duration: 1000,
    easing: 'swing',
    step: function () {
      $this.text(Math.ceil(this.Counter));
    }
  });
});

Update: If you want to display decimal numbers, then instead of rounding the value with Math.ceil you can round up to 2 decimals for instance with value.toFixed(2):

step: function () {
  $this.text(this.Counter.toFixed(2));
}

According to Laravel 5.2 docs, your publicly accessible files should be put in directory

storage/app/public

To make them accessible from the web, you should create a symbolic link from public/storage to storage/app/public.

ln -s /path/to/laravel/storage/app/public /path/to/laravel/public/storage

Now you can create in your view an URL to the files using the asset helper:

echo asset('storage/file.txt');

The following is nasty, but serves to demonstrate how you can treat functions like any other kind of object.

var foo = function () { alert('default function'); }

function pickAFunction(a_or_b) {
    var funcs = {
        a: function () {
            alert('a');
        },
        b: function () {
            alert('b');
        }
    };
    foo = funcs[a_or_b];
}

foo();
pickAFunction('a');
foo();
pickAFunction('b');
foo();

For TortoiseGit 1.8.1.2 or later, there is a GUI to switch on/off credential helper.

It supports git-credential-wincred and git-credential-winstore.

TortoiseGit 1.8.16 add support for git-credential-manager (Git Credential Manager, the successor of git-credential-winstore)

For the first time you sync you are asked for user and password, you enter them and they will be saved to Windows credential store. It won't ask for user or password the next time you sync.

To use: Right click → TortoiseGit → Settings → Git → Credential. Select Credential helper: wincred - this repository only / wincred - current Windows user

For excluding multiple file types, you can use '+' to concatenate other lists. For example:

xcopy /r /d /i /s /y /exclude:excludedfileslist1.txt+excludedfileslist2.txt C:\dev\apan C:\web\apan

This error also occurred when I compiled with MinGW using gcc with the following options: -lstdc++ -lm, rather than g++

I did not notice these options, and added: -static-libgcc -static-libstdc++

I still got the error, and finally realized I was using gcc, and changed the compiler to g++ and removed -stdc++ and -lm, and everything linked fine.

(I was using LINK.c rather than LINK.cpp... use make -pn | less to see what everything does!)

I don't know why the previous author was using gcc with -stdc++. I don't see any reason not to use g++ which will link with stdc++ automatically... and as far as I know, provide other benefits (it is the c++ compiler after all).

1. this is just simple here i'm appending html table into a div at the end
2. we can achieve this or any thing with a simple concept of calling a JavaScript function when we want (here on drop.)
3. In this example you can drag & drop any number of tables, new table will be added below the last table exists in the div other wise it will be the first table in the div.
4. here we can add text between tables or we can say the section where we drop tables is editable we can type text between tables.

Thanks... :)

Use json_decode to transform your JSON into a PHP array. Example:

$json = '{"a":"b"}';
$array = json_decode($json, true);
echo $array['a']; // b

You can use Reference Assistant extension from the Visual Studio extension gallery.

Used and works for Visual Studio 2010.

I tried this and got a ';'-delimited csv file:

--#SET TERMINATOR % 
EXPORT TO result.csv OF DEL MODIFIED BY CHARDEL;

=> true
>> "[email protected]".is_a? Integer
=> false
>> nil.is_a? Integer
=> false

Because the number can be up to 15 digits, you'll need to cast to an 64 bit (8-byte) integer. Try this:

SELECT * FROM table
WHERE myint = mytext::int8

The :: cast operator is historical but convenient. Postgres also conforms to the SQL standard syntax

myint = cast ( mytext as int8)

If you have literal text you want to compare with an int, cast the int to text:

SELECT * FROM table
WHERE myint::varchar(255) = mytext

Your code "for /f "tokens=* delims=" %%x in (a.txt) do echo %%x" will work on most Windows Operating Systems unless you have modified commands.

So you could instead "cd" into the directory to read from before executing the "for /f" command to follow out the string. For instance if the file "a.txt" is located at C:\documents and settings\%USERNAME%\desktop\a.txt then you'd use the following.

cd "C:\documents and settings\%USERNAME%\desktop"
for /f "tokens=* delims=" %%x in (a.txt) do echo %%x
echo.
echo.
echo.
pause >nul
exit

But since this doesn't work on your computer for x reason there is an easier and more efficient way of doing this. Using the "type" command.

@echo off
color a
cls
cd "C:\documents and settings\%USERNAME%\desktop"
type a.txt
echo.
echo.
pause >nul
exit

Or if you'd like them to select the file from which to write in the batch you could do the following.

@echo off
:A
color a
cls
echo Choose the file that you want to read.
echo.
echo.
tree
echo.
echo.
echo.
set file=
set /p file=File:
cls
echo Reading from %file%
echo.
type %file%
echo.
echo.
echo.
set re=
set /p re=Y/N?:
if %re%==Y goto :A
if %re%==y goto :A
exit

Of course you can, say for example, you want to use the DescriptionAttribue on your enum values:

using System.ComponentModel.DataAnnotations;

public enum Duration 
{ 
    [Description("Eight hours")]
    Day,

    [Description("Five days")]
    Week,

    [Description("Twenty-one days")] 
    Month 
}

Now you want to be able to do something like:

Duration duration = Duration.Week;
var description = duration.GetDescription(); // will return "Five days"

Your extension method GetDescription() can be written as follows:

using System.ComponentModel;
using System.Reflection;

public static string GetDescription(this Enum value)
{
    FieldInfo fieldInfo = value.GetType().GetField(value.ToString());
    if (fieldInfo == null) return null;
    var attribute = (DescriptionAttribute)fieldInfo.GetCustomAttribute(typeof(DescriptionAttribute));
    return attribute.Description;
}

Just to confirm: You are sure you are running MySQL 5.7, and not MySQL 5.6 or earlier version. And the plugin column contains "mysql_native_password". (Before MySQL 5.7, the password hash was stored in a column named password. Starting in MySQL 5.7, the password column is removed, and the password has is stored in the authentication_string column.) And you've also verified the contents of authentication string matches the return from PASSWORD('mysecret'). Also, is there a reason we are using DML against the mysql.user table instead of using the SET PASSWORD FOR syntax? – spencer7593

So Basically Just make sure that the Plugin Column contains "mysql_native_password".

Not my work but I read comments and noticed that this was stated as the answer but was not posted as a possible answer yet.

Altova's DiffDog has free 30-day trial and should do what you're looking for:

Edit: After Docker 1.9, the docker network command (see below https://stackoverflow.com/a/35184695/977939) is the recommended way to achieve this.

My solution is to set up a dnsmasq on the host to have DNS record automatically updated: "A" records have the names of containers and point to the IP addresses of the containers automatically (every 10 sec). The automatic updating script is pasted here:

#!/bin/bash

# 10 seconds interval time by default
INTERVAL=${INTERVAL:-10}

# dnsmasq config directory
DNSMASQ_CONFIG=${DNSMASQ_CONFIG:-.}

# commands used in this script
DOCKER=${DOCKER:-docker}
SLEEP=${SLEEP:-sleep}
TAIL=${TAIL:-tail}

declare -A service_map

while true
do
    changed=false
    while read line
    do
        name=${line##* }
        ip=$(${DOCKER} inspect --format '{{.NetworkSettings.IPAddress}}' $name)
        if [ -z ${service_map[$name]} ] || [ ${service_map[$name]} != $ip ] # IP addr changed
        then
            service_map[$name]=$ip
            # write to file
            echo $name has a new IP Address $ip >&2
            echo "host-record=$name,$ip"  > "${DNSMASQ_CONFIG}/docker-$name"
            changed=true
        fi
    done < <(${DOCKER} ps | ${TAIL} -n +2)

    # a change of IP address occured, restart dnsmasq
    if [ $changed = true ]
    then
        systemctl restart dnsmasq
    fi

    ${SLEEP} $INTERVAL
done

Make sure your dnsmasq service is available on docker0. Then, start your container with --dns HOST_ADDRESS to use this mini dns service.

Having the same error trying to install matplotlib for Python 3, those solutions didn't work for me. It was just a matter of dependencies, though it wasn't clear in the error message.

I used sudo apt-get build-dep python3-matplotlib then sudo pip3 install matplotlib and it worked.

Hope it'll help !

The answer given by Nico O is correct. However this doesn't get the desired result on Internet Explorer 10 to 11 and Firefox.

For IE, I found that changing

.flex > div
{
   flex: 1 0 50%;
}

to

.flex > div
{
   flex: 1 0 45%;
}

seems to do the trick. Don't ask me why, I haven't gone any further into this but it might have something to do with how IE renders the border-box or something.

In the case of Firefox I solved it by adding

display: inline-block;

to the items.

To make multiple checking statements more readable (and avoid nested ifs):

var tmp = 'Test[[email protected]]';

var posStartEmail = undefined;
var posEndEmail = undefined;
var email = undefined;

do {
    if (tmp.toLowerCase().substring(0,4) !== 'test') { break; }

    posStartEmail = tmp.toLowerCase().substring(4).indexOf('[');
    posEndEmail = tmp.toLowerCase().substring(4).indexOf(']');

    if (posStartEmail === -1 || posEndEmail === -1) { break; }

    email = tmp.substring(posStartEmail+1+4,posEndEmail);

    if (email.indexOf('@') === -1) { break; }

// all checks are done - do what you intend to do

    alert ('All checks are ok')

    break; // the most important break of them all

} while(true);

By removing the parameter from the anonymous function will be available in the body.

    myButton.onclick = function() { alert(myMessage); };

To cast, the actual object must be of a Type equal to or derived from the Type you are attempting to cast to...

or, to state it in the opposite way, the Type you are trying to cast it to must be the same as, or a base class of, the actual type of the object.

if your actual object is of type Baseclass, then you can't cast it to a derived class Type...

Fake loop that breaks on the first iteration:

$key = $value = NULL;
foreach ($array as $key => $value) {
    break;
}

echo "$key = $value\n";

Or use each() (warning: deprecated as of PHP 7.2.0):

reset($array);
list($key, $value) = each($array);

echo "$key = $value\n";

You could embed your code in C/C++ and compile Embedding Python in Another Application

embedded.c

#include <Python.h>

int
main(int argc, char *argv[])
{
  Py_SetProgramName(argv[0]);  /* optional but recommended */
  Py_Initialize();
  PyRun_SimpleString("print('Hello world !')");
  Py_Finalize();
  return 0;
}

In Ubuntu/Debian

$ sudo apt-get install python-dev

In Centos/Redhat/Fedora

$ sudo yum install python-devel

compile with

$ gcc -o embedded -fPIC -I/usr/include/python2.7 -lpython2.7 embedded.c

run with

$ chmod u+x ./embedded
$ time ./embedded
Hello world !

real  0m0.014s
user  0m0.008s
sys 0m0.004s

initial script: hello_world.py:

print('Hello World !')

run the script

$ time python hello_world.py
Hello World !

real  0m0.014s
user  0m0.008s
sys 0m0.004s

however some strings of the python code may be found in the compiled file

$ grep "Hello" ./embedded
Binary file ./embedded matches

$ grep "Hello World" ./embedded
$

In case you want an extra bit of obfuscation you could use base64

...
PyRun_SimpleString("import base64\n"
                  "base64_code = 'your python code in base64'\n"
                  "code = base64.b64decode(base64_code)\n"
                  "exec(code)");
...

e.g:

create the base 64 string of your code

$ base64 hello_world.py
cHJpbnQoJ0hlbGxvIFdvcmxkICEnKQoK

embedded_base64.c

#include <Python.h>

int
main(int argc, char *argv[])
{
  Py_SetProgramName(argv[0]);  /* optional but recommended */
  Py_Initialize();
  PyRun_SimpleString("import base64\n"
                    "base64_code = 'cHJpbnQoJ0hlbGxvIFdvcmxkICEnKQoK'\n"
                    "code = base64.b64decode(base64_code)\n"
                    "exec(code)\n");
  Py_Finalize();
  return 0;
}

all commands

$ gcc -o embedded_base64 -fPIC -I/usr/include/python2.7 -lpython2.7 ./embedded_base64.c
$ chmod u+x ./embedded_base64

$ time ./embedded_base64
Hello World !

user  0m0.008s
sys 0m0.004s

$ grep "Hello" ./embedded_base64

Swift 3:

    do {
        let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String:Any]

    }
}

I had the same problem.

Solved by sharing internet connection (on the hosting OS).

Network Connection Properties -> advanced -> Allow other users to connect...

Below Code snippet will surely work:

    InternetExplorerOptions ops = new InternetExplorerOptions();
    // ops.ignoreZoomSettings(); -- Not necessarily in case 100% zoom.
    ops.introduceFlakinessByIgnoringSecurityDomains(); -- Necessary to skip protected 
     mode setup

    System.setProperty("webdriver.ie.driver",
            <path>\\IEDriverServer.exe");
    WebDriver dr = new InternetExplorerDriver(ops);

$('.button1').click(function() {
   document.location.href='/index.php?id=' + $(this).attr('id');
});

Try putting both columns in the same orderby.

orderby p.LowestPrice.HasValue descending, p.LowestPrice

Otherwise each orderby is a separate operation on the collection re-ordering it each time.

This should order the ones with a value first, "then" the order of the value.

Powershell Solution:

If you're running windows, you can use PowerShell to remove multiple branches at once...

git branch -D ((git branch | Select-String -Pattern '^\s*3\.2\..*') | foreach{$_.ToString().Trim()})
//this will remove all branches starting with 3.2.

git branch -D ((git branch | Select-String -Pattern 'feature-*') | foreach{$_.ToString().Trim()})
// this will delete all branches that contains the word "feature-" as a substring.

You can also fine tune how the pattern matching should work using Powershell's Select-String command. Take a look at powershell docs.

The shortest in terms of lines of code i can think of is for the first question.

>>> import numpy as np
>>> p = np.array([[1,2],[3,4]])

>>> p = np.append(p, [[5,6]], 0)
>>> p = np.append(p, [[7],[8],[9]],1)

>>> p
array([[1, 2, 7],
   [3, 4, 8],
   [5, 6, 9]])

And the for the second question

    p = np.array(range(20))
>>> p.shape = (4,5)
>>> p
array([[ 0,  1,  2,  3,  4],
       [ 5,  6,  7,  8,  9],
       [10, 11, 12, 13, 14],
       [15, 16, 17, 18, 19]])
>>> n = 2
>>> p = np.append(p[:n],p[n+1:],0)
>>> p = np.append(p[...,:n],p[...,n+1:],1)
>>> p
array([[ 0,  1,  3,  4],
       [ 5,  6,  8,  9],
       [15, 16, 18, 19]])

This will select the last two iems of a list:

li:nth-last-child(-n+2) {color:red;}

<ul>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
</ul>

Study up on multidimensional arrays. This question might help.

If use data from json and use Datatable v 1.10.19, you can do this:

More info

$(document).ready(function() {
     $('#example').dataTable( {

        columns= [
          { 
           "data": "name_data",
           "visible": false
           }
        ]
  });
});

Try with:

select TO_CHAR(dates,'dd/MM/yyy hh24:mi') from (  SELECT min  (TO_DATE(a.PAYM_DATE)) as dates from user_payment a )

I use this one:

find . -name ".git" -type d | sed 's/\/.git//' |  xargs -P10 -I{} git -C {} pull

Universal: Updates all git repositories that are below current directory.

You can use the HttpWebRequest class to do so.

Example here:

using System;
using System.Net;
using System.Text;
using System.IO;


    public class Test
    {
        // Specify the URL to receive the request.
        public static void Main (string[] args)
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create (args[0]);

            // Set some reasonable limits on resources used by this request
            request.MaximumAutomaticRedirections = 4;
            request.MaximumResponseHeadersLength = 4;
            // Set credentials to use for this request.
            request.Credentials = CredentialCache.DefaultCredentials;
            HttpWebResponse response = (HttpWebResponse)request.GetResponse ();

            Console.WriteLine ("Content length is {0}", response.ContentLength);
            Console.WriteLine ("Content type is {0}", response.ContentType);

            // Get the stream associated with the response.
            Stream receiveStream = response.GetResponseStream ();

            // Pipes the stream to a higher level stream reader with the required encoding format. 
            StreamReader readStream = new StreamReader (receiveStream, Encoding.UTF8);

            Console.WriteLine ("Response stream received.");
            Console.WriteLine (readStream.ReadToEnd ());
            response.Close ();
            readStream.Close ();
        }
    }

/*
The output from this example will vary depending on the value passed into Main 
but will be similar to the following:

Content length is 1542
Content type is text/html; charset=utf-8
Response stream received.
<html>
...
</html>

*/

I know this is kind of old but if you are reading the contents of a SqlDataReader into a class, then this will be very handy. the column names of reader and class should be same

public static List<T> Fill<T>(this SqlDataReader reader) where T : new()
        {
            List<T> res = new List<T>();
            while (reader.Read())
            {
                T t = new T();
                for (int inc = 0; inc < reader.FieldCount; inc++)
                {
                    Type type = t.GetType();
                    string name = reader.GetName(inc);
                    PropertyInfo prop = type.GetProperty(name);
                    if (prop != null)
                    {
                        if (name == prop.Name)
                        {
                            var value = reader.GetValue(inc);
                            if (value != DBNull.Value)
                            { 
                                prop.SetValue(t, Convert.ChangeType(value, prop.PropertyType), null);
                            }
                            //prop.SetValue(t, value, null);

                        }
                    }
                }
                res.Add(t);
            }
            reader.Close();

            return res;
        }

There are many other binaries that need to be linked so I think it's much better to try something like sudo update-alternatives --all and choosing the right alternatives for everything else besides java and javac.

Blanket.js works perfect too.

npm install --save-dev blanket

in front of your test/tests.js

require('blanket')({
    pattern: function (filename) {
        return !/node_modules/.test(filename);
    }
});

run mocha -R html-cov > coverage.html

Please take a good look here: http://jquerymobile.com/test/docs/api/methods.html

$.mobile.changePage() is to change from one page to another, and the parameter can be a url or a page object. ( only #result will also work )

$.mobile.page() isn't recommended anymore, please use .trigger( "create"), see also: JQuery Mobile .page() function causes infinite loop?

Important: Create vs. refresh: An important distinction

Note that there is an important difference between the create event and refresh method that some widgets have. The create event is suited for enhancing raw markup that contains one or more widgets. The refresh method that some widgets have should be used on existing (already enhanced) widgets that have been manipulated programmatically and need the UI be updated to match.

For example, if you had a page where you dynamically appended a new unordered list with data-role=listview attribute after page creation, triggering create on a parent element of that list would transform it into a listview styled widget. If more list items were then programmatically added, calling the listview’s refresh method would update just those new list items to the enhanced state and leave the existing list items untouched.

$.mobile.refresh() doesn't exist i guess

So what are you using for your results? A listview? Then you can update it by doing:

$('ul').listview('refresh');

Example: http://operationmobile.com/dont-forget-to-call-refresh-when-adding-items-to-your-jquery-mobile-list/

Otherwise you can do:

$('#result').live("pageinit", function(){ // or pageshow
    // your dom manipulations here
});

My last adventure with MSDTC and this error today turned out to be a DNS issue. You're on the right track asking if the machines are on the same domain, EBarr. Terrific list for this issue, by the way!

My situation: I needed a server in a child domain to be able to run distributed transactions against a server in the parent domain through a firewall. I've used linked servers quite a bit over the years, so I had all the usual settings in SQL for a linked server and in MSDTC that Ian documented so nicely above. I set up MSDTC with a range of TCP ports (5000-5200) to use on both servers, and arranged for a firewall hole between the boxes for ports 1433 and 5000-5200. That should have worked. The linked server tested OK and I could query the remote SQL server via the linked server nicely, but I couldn't get it to allow a distributed transaction. I could even see a connection on the QA server from the DEV server, but something wasn't making the trip back.

I could PING the DEV server from QA using a FQDN like: PING DEVSQL.dev.domain.com

I could not PING the DEV server with just the machine name: PING DEVSQL

The DEVSQL server was supposed to be a member of both domains, but the name wasn't resolving in the parent domain's DNS... something had happened to the machine account for DEVSQL in the parent domain. Once we added DEVSQL to the DNS for the parent domain, and "PING DEVSQL" worked from the remote QA server, this issue was resolved for us.

I hope this helps!

If you don't want to use a submission service like Litmus (Litmus is the best, BTW) then you're just going to have to run Outlook 2007 to test your email.

It sounds like you want something a little more automatic (though I'm not sure why), but fortunately Outlook is easy to automate using Visual Basic for Applications (VBA).

You can write a VBA tool that runs from the command line to generate an email, load the email up in Outlook, and even capture a screenshot if you wish. (Presumably this is what the Litmus team does on the backend.)

(BTW, do not attempt to use MS Word to test mail; the renderer is similar but subtle differences in page layout can affect the rendering of your email.)

You can do it using array module. array module is part of python standard library:

from array import array
from itertools import repeat

a = array("i", repeat(0, 10))
# or
a = array("i", [0]*10)

repeat function repeats 0 value 10 times. It's more memory efficient than [0]*10, since it doesn't allocate memory, but repeats returning the same number x number of times.

I don't like setting CLASSPATH. CLASSPATH is a global variable and as such it is evil:

• If you modify it in one script, suddenly some java programs will stop working.
• If you put there the libraries for all the things which you run, and it gets cluttered.
• You get conflicts if two different applications use different versions of the same library.
• There is no performance gain as libraries in the CLASSPATH are not shared - just their name is shared.
• If you put the dot (.) or any other relative path in the CLASSPATH that means a different thing in each place - that will cause confusion, for sure.

Therefore the preferred way is to set the classpath per each run of the jvm, for example:

java -Xmx500m -cp ".:../somejar.jar:../mysql-connector-java-5.1.6-bin.jar"    "folder.subfolder../dit1/some.xml

If it gets long the standard procedure is to wrap it in a bash or batch script to save typing.
