We had a situation where IE forced us to post as text/plain, so we had to manually parse the parameters using getReader. The servlet was being used for long polling, so when AsyncContext::dispatch was executed after a delay, it was literally reposting the request empty handed.

So I just stored the post in the request when it first appeared by using HttpServletRequest::setAttribute. The getReader method empties the buffer, where getParameter empties the buffer too but stores the parameters automagically.

    String input = null;

    // we have to store the string, which can only be read one time, because when the
    // servlet awakens an AsyncContext, it reposts the request and returns here empty handed
    if ((input = (String) request.getAttribute("com.xp.input")) == null) {
        StringBuilder buffer = new StringBuilder();
        BufferedReader reader = request.getReader();

        String line;
        while((line = reader.readLine()) != null){
            buffer.append(line);
        }
        // reqBytes = buffer.toString().getBytes();

        input = buffer.toString();
        request.setAttribute("com.xp.input", input);
    }

    if (input == null) {
        response.setContentType("text/plain");
        PrintWriter out = response.getWriter();
        out.print("{\"act\":\"fail\",\"msg\":\"invalid\"}");
    }       

Try to rebuild openssl (if you are linking with it) with flag no-threads.

Then try to link like this:

target_link_libraries(${project_name} dl pthread crypt m ${CMAKE_DL_LIBS})

Or the minified version of the file...

<script src="angular-route.min.js"></script>

More information about this here:

"This error occurs when a module fails to load due to some exception. The error message above should provide additional context."

"In AngularJS 1.2.0 and later, ngRoute has been moved to its own module. If you are getting this error after upgrading to 1.2.x, be sure that you've installed ngRoute."

Listed under section Error: $injector:modulerr Module Error in the Angularjs docs.

String runtimeVersion = System.getProperty("java.runtime.version");

should return you a string along the lines of:

1.5.0_01-b08

That's the version of Java that Eclipse is using to run your code which is not necessarily the same version that's being used to run Eclipse itself.

Remove the inline event handler and do it completly unobtrusive, like

?$('????#race').bind('change', function(){
  var $this = $(this),
      id    = $this[0].id;

  if(/^other$/.test($(this).val())){
      $this.replaceWith($('<input/>', {
          type: 'text',
          name:  id,
          id: id
      }));
  }
});???

Compile:

gcc -ggdb3 -O0 -o main -std=c99 -Wall -Wextra -pedantic main.c -lGL -lGLU -lglut

Run with glOrtho:

./main 1

Run with glFrustrum:

./main

Tested on Ubuntu 18.10.

Schema

Ortho: camera is a plane, visible volume a rectangle:

Frustrum: camera is a point,visible volume a slice of a pyramid:

Image source.

Parameters

We are always looking from +z to -z with +y upwards:

glOrtho(left, right, bottom, top, near, far)

• left: minimum x we see
• right: maximum x we see
• bottom: minimum y we see
• top: maximum y we see
• -near: minimum z we see. Yes, this is -1 times near. So a negative input means positive z.
• -far: maximum z we see. Also negative.

Schema:

Image source.

How it works under the hood

In the end, OpenGL always "uses":

glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);

If we use neither glOrtho nor glFrustrum, that is what we get.

glOrtho and glFrustrum are just linear transformations (AKA matrix multiplication) such that:

• glOrtho: takes a given 3D rectangle into the default cube
• glFrustrum: takes a given pyramid section into the default cube

This transformation is then applied to all vertexes. This is what I mean in 2D:

Image source.

The final step after transformation is simple:

• remove any points outside of the cube (culling): just ensure that x, y and z are in [-1, +1]
• ignore the z component and take only x and y, which now can be put into a 2D screen

With glOrtho, z is ignored, so you might as well always use 0.

One reason you might want to use z != 0 is to make sprites hide the background with the depth buffer.

Deprecation

glOrtho is deprecated as of OpenGL 4.5: the compatibility profile 12.1. "FIXED-FUNCTION VERTEX TRANSFORMATIONS" is in red.

So don't use it for production. In any case, understanding it is a good way to get some OpenGL insight.

Modern OpenGL 4 programs calculate the transformation matrix (which is small) on the CPU, and then give the matrix and all points to be transformed to OpenGL, which can do the thousands of matrix multiplications for different points really fast in parallel.

Manually written vertex shaders then do the multiplication explicitly, usually with the convenient vector data types of the OpenGL Shading Language.

Since you write the shader explicitly, this allows you to tweak the algorithm to your needs. Such flexibility is a major feature of more modern GPUs, which unlike the old ones that did a fixed algorithm with some input parameters, can now do arbitrary computations.

Output:

The matrix for glOrtho is really simple, composed only of scaling and translation:

scalex, 0,      0,      translatex,
0,      scaley, 0,      translatey,
0,      0,      scalez, translatez,
0,      0,      0,      1

as mentioned in the OpenGL 2 docs.

The glFrustum matrix is not too hard to calculate by hand either, but starts getting annoying. Note how frustum cannot be made up with only scaling and translations like glOrtho, more info at: https://gamedev.stackexchange.com/a/118848/25171

The GLM OpenGL C++ math library is a popular choice for calculating such matrices. http://glm.g-truc.net/0.9.2/api/a00245.html documents both an ortho and frustum operations.

A class is a blueprint which you use to create objects. An object is an instance of a class - it's a concrete 'thing' that you made using a specific class. So, 'object' and 'instance' are the same thing, but the word 'instance' indicates the relationship of an object to its class.

This is easy to understand if you look at an example. For example, suppose you have a class House. Your own house is an object and is an instance of class House. Your sister's house is another object (another instance of class House).

// Class House describes what a house is
class House {
    // ...
}

// You can use class House to create objects (instances of class House)
House myHouse = new House();
House sistersHouse = new House();

The class House describes the concept of what a house is, and there are specific, concrete houses which are objects and instances of class House.

Note: This is exactly the same in Java as in all object oriented programming languages.

Great answers, but just wanted to mention a gotcha that "pass" keyword will not work in the if/else part of the list-comprehension (as posted in the examples mentioned above).

#works
list1 = [10, 20, 30, 40, 50]
newlist2 = [x if x > 30 else x**2 for x in list1 ]
print(newlist2, type(newlist2))

#but this WONT work
list1 = [10, 20, 30, 40, 50]
newlist2 = [x if x > 30 else pass for x in list1 ]
print(newlist2, type(newlist2))

This is tried and tested on python 3.4. Error is as below:

newlist2 = [x if x > 30 else pass for x in list1 ]                                    
SyntaxError: invalid syntax

So, try to avoid pass-es in list comprehensions

Yes you can pass the model that you have shown using

return RedirectToAction("GetStudent", "Student", student1 );

assuming student1 is an instance of Student

which will generate the following url (assuming your using the default routes and the value of student1 are ID=4 and Name="Amit")

.../Student/GetStudent/4?Name=Amit

Internally the RedirectToAction() method builds a RouteValueDictionary by using the .ToString() value of each property in the model. However, binding will only work if all the properties in the model are simple properties and it fails if any properties are complex objects or collections because the method does not use recursion. If for example, Student contained a property List<string> Subjects, then that property would result in a query string value of

....&Subjects=System.Collections.Generic.List'1[System.String]

and binding would fail and that property would be null

The match attribute indicates on which parts the template transformation is going to be applied. In that particular case the "/" means the root of the xml document. The value you have to provide into the match attribute should be XPath expression. XPath is the language you have to use to refer specific parts of the target xml file.

To gain a meaningful understanding of what else you can put into match attribute you need to understand what xpath is and how to use it. I suggest yo look at links I've provided for youat the bottom of the answer.

Could I write "table" or any other html tag instead of "/" ?

Yes you can. But this depends what exactly you are trying to do. if your target xml file contains HMTL elements and you are triyng to apply this xsl:template on them it makes sense to use table, div or anithing else.

Here a few links:

• XSL templates
• XPath
• A good book about XML - Beginning XML

Xcode 12.2 solution: Go to:

This is when you want a AlertDialog in a Fragment

            AlertDialog.Builder adb = new AlertDialog.Builder(getActivity());
            adb.setTitle("My alert Dialogue \n");
            adb.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {

                  //some code

            } });
            adb.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {

                 dialog.dismiss();

                } });
            adb.show();

In my case.. following steps resolved:

There was a column value which was set to "Update" - replaced it with Edit (non sql keyword) There was a space in one of the column names (removed the extra space or trim)

Here is a link from developer.nokia.com wiki pages, which explains how to install Windows Phone 8 SDK on a Virtual Machine with Working Emulator

And another link here

AFAIK, it is not possible to directly install WP8 SDK in Windows 7, because WP8 sdk is VS 2012 supported and also its emulator works on a Hyper-V (which is integrated into the Windows 8).

You should add some prefixes, check caniuse.

Android uses some files called resources where values are stored for the XML files.

Now when you use @id/ for an XML object, It is trying to refer to an id which is already registered in the values files. On the other hand, when you use @+id/ it registers a new id in the values files as implied by the '+' symbol.

Hope this helps :).

The answer is to use Welford's algorithm, which is very clearly defined after the "naive methods" in:

• Wikipedia: Algorithms for calculating variance

It's more numerically stable than either the two-pass or online simple sum of squares collectors suggested in other responses. The stability only really matters when you have lots of values that are close to each other as they lead to what is known as "catastrophic cancellation" in the floating point literature.

You might also want to brush up on the difference between dividing by the number of samples (N) and N-1 in the variance calculation (squared deviation). Dividing by N-1 leads to an unbiased estimate of variance from the sample, whereas dividing by N on average underestimates variance (because it doesn't take into account the variance between the sample mean and the true mean).

I wrote two blog entries on the topic which go into more details, including how to delete previous values online:

• Computing Sample Mean and Variance Online in One Pass
• Deleting Values in Welford’s Algorithm for Online Mean and Variance

You can also take a look at my Java implement; the javadoc, source, and unit tests are all online:

• Javadoc: stats.OnlineNormalEstimator
• Source: stats.OnlineNormalEstimator.java
• JUnit Source: test.unit.stats.OnlineNormalEstimatorTest.java
• LingPipe Home Page

The actual answer to this (reduce) problem is: Just use a loop!

initial_value = 0
for x in the_list:
    initial_value += x #or any function.

This will be faster than a reduce and things like PyPy can optimize loops like that.

BTW, the sum case should be solved with the sum function

I had a similar issue in windows 7 + ubuntu 12.04 as guest. I resolved by

• open 'network and sharing center' in windows
• right click 'nw-bridge' -> 'properties'
• Select "virtual box host only network" for the option "select adapters you want to use to connect computers on your local network"
• go to virtual box.. select the network type as NAT.

ssh -v -L 8783:localhost:8783 [email protected]
...
channel 3: open failed: connect failed: Connection refused

When you connect to port 8783 on your local system, that connection is tunneled through your ssh link to the ssh server on server.com. From there, the ssh server makes TCP connection to localhost port 8783 and relays data between the tunneled connection and the connection to target of the tunnel.

The "connection refused" error is coming from the ssh server on server.com when it tries to make the TCP connection to the target of the tunnel. "Connection refused" means that a connection attempt was rejected. The simplest explanation for the rejection is that, on server.com, there's nothing listening for connections on localhost port 8783. In other words, the server software that you were trying to tunnel to isn't running, or else it is running but it's not listening on that port.

Edit 08/13/2018: There is now support for native array operations in Cloud Firestore. See Doug's answer below.

There is currently no way to update a single array element (or add/remove a single element) in Cloud Firestore.

This code here:

firebase.firestore()
.collection('proprietary')
.doc(docID)
.set(
  { sharedWith: [{ who: "[email protected]", when: new Date() }] },
  { merge: true }

This says to set the document at proprietary/docID such that sharedWith = [{ who: "[email protected]", when: new Date() } but to not affect any existing document properties. It's very similar to the update() call you provided however the set() call with create the document if it does not exist while the update() call will fail.

So you have two options to achieve what you want.

Option 1 - Set the whole array

Call set() with the entire contents of the array, which will require reading the current data from the DB first. If you're concerned about concurrent updates you can do all of this in a transaction.

Option 2 - Use a subcollection

You could make sharedWith a subcollection of the main document. Then adding a single item would look like this:

firebase.firestore()
  .collection('proprietary')
  .doc(docID)
  .collection('sharedWith')
  .add({ who: "[email protected]", when: new Date() })

Of course this comes with new limitations. You would not be able to query documents based on who they are shared with, nor would you be able to get the doc and all of the sharedWith data in a single operation.

The problem is that buttons render differently across browsers. In Firefox, 24px is sufficient to cover the default padding and space allowed for your "A" character and center it. In IE and Chrome, it does not, so it defaults to the minimum value needed to cover the left padding and the text without cutting it off, but without adding any additional width to the button.

You can either increase the width, or as suggested above, alter the padding. If you take away the explicit width, it should work too.

You can test it here: https://regex101.com/r/kB0rQ4/1

Try this CSS:

body {
  margin: 0;
  padding: 0;
}

.logo {
  float: left;
}
/* ~~ Top Navigation Bar ~~ */

#navigation-container {
  width: 1200px;
  margin: 0 auto;
  height: 70px;
}

.navigation-bar {
  background-color: #352d2f;
  height: 70px;
  width: 100%;
}

#navigation-container img {
  float: left;
}

#navigation-container ul {
  padding: 0px;
  margin: 0px;
  text-align: center;
  display:inline-block;
}

#navigation-container li {
  list-style-type: none;
  padding: 0px;
  height: 24px;
  margin-top: 4px;
  margin-bottom: 4px;
  display: inline;
}

#navigation-container li a {
  color: white;
  font-size: 16px;
  font-family: "Trebuchet MS", Arial, Helvetica, sans-serif;
  text-decoration: none;
  line-height: 70px;
  padding: 5px 15px;
  opacity: 0.7;
}

#menu {
  float: right;
}

Depending on which style you want to set, you have to use different methods. TextAppearance stuff has its own setter, TypeFace has its own setter, background has its own setter, etc.

How wide is the text column?

With a GROUP BY there's not much you can do to avoid a data scan (at least an index scan).

I'd recommend:

1. If possible, changing the schema to remove duplication of text data. This way the count will happen on a narrow foreign key field in the 'many' table.

2. Alternatively, creating a generated column with a HASH of the text, then GROUP BY the hash column. Again, this is to decrease the workload (scan through a narrow column index)

Edit:

Your original question did not quite match your edit. I'm not sure if you're aware that the COUNT, when used with a GROUP BY, will return the count of items per group and not the count of items in the entire table.

To really get this clear, here's my for-beginners answer: You inputed the arguments in the wrong order.
A keyword argument has this style:

nullable=True, unique=False

A fixed parameter should be defined: True, False, etc. A non-keyword argument is different:

name="Ricardo", fruit="chontaduro" 

This syntax error asks you to first put name="Ricardo" and all of its kind (non-keyword) before those like nullable=True.

This was driving me bonkers as the .astype() solution above didn't work for me. But I found another way. Haven't timed it or anything, but might work for others out there:

t1 = pd.to_datetime('1/1/2015 01:00')
t2 = pd.to_datetime('1/1/2015 03:30')

print pd.Timedelta(t2 - t1).seconds / 3600.0

...if you want hours. Or:

print pd.Timedelta(t2 - t1).seconds / 60.0

...if you want minutes.

Here is the formula I'm using

=IF( ISNUMBER(FIND(".",A1)), LEN(A1) - FIND(".",A1), 0 )

Using StringSolver tools (windows & Linux bash) which process by examples:

filter fghfilea ok fghreport ok notfghfile notok; mv --all --filter fghfilea jklfilea

It first computes a filter based on examples, where the input is the file names and the output (ok and notok, arbitrary strings). If filter had the option --auto or was invoked alone after this command, it would create a folder ok and a folder notok and push files respectively to them.

Then using the filter, the mv command is a semi-automatic move which becomes automatic with the modifier --auto. Using the previous filter thanks to --filter, it finds a mapping from fghfilea to jklfilea and then applies it on all filtered files.

Other one-line solutions

Other equivalent ways of doing the same (each line is equivalent), so you can choose your favorite way of doing it.

filter fghfilea ok fghreport ok notfghfile notok; mv --filter fghfilea jklfilea; mv
filter fghfilea ok fghreport ok notfghfile notok; auto --all --filter fghfilea "mv fghfilea jklfilea"
# Even better, automatically infers the file name
filter fghfilea ok fghreport ok notfghfile notok; auto --all --filter "mv fghfilea jklfilea"

Multi-step solution

To carefully find if the commands are performing well, you can type the following:

filter fghfilea ok
filter fghfileb ok
filter fghfileb notok

and when you are confident that the filter is good, perform the first move:

mv fghfilea jklfilea

If you want to test, and use the previous filter, type:

mv --test --filter

If the transformation is not what you wanted (e.g. even with mv --explain you see that something is wrong), you can type mv --clear to restart moving files, or add more examples mv input1 input2 where input1 and input2 are other examples

When you are confident, just type

mv --filter

and voilà! All the renaming is done using the filter.

According to the latest doc you can do the following-

Add a day

moment().add(1, 'days').calendar();

Add Year

moment().add(1, 'years').calendar();

Add Month

moment().add(1, 'months').calendar();

Try the following:

    ....
    character(len=30) :: filename  ! length depends on expected names
    integer           :: inuit
    ....
    do i=1,n
        write(filename,'("output",i0,".txt")') i
        open(newunit=iunit,file=filename,...)
        ....
        close(iunit)
    enddo
    ....

Where "..." means other appropriate code for your purpose.

To add to tacaswell's answer, the colorbar() function has an optional cax input you can use to pass an axis on which the colorbar should be drawn. If you are using that input, you can directly set a label using that axis.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

fig, ax = plt.subplots()
heatmap = ax.imshow(data)
divider = make_axes_locatable(ax)
cax = divider.append_axes('bottom', size='10%', pad=0.6)
cb = fig.colorbar(heatmap, cax=cax, orientation='horizontal')

cax.set_xlabel('data label')  # cax == cb.ax

The most likely place to find this sort of information is in the event viewer (under Administrative tools in XP or run eventvwr) This is where most services log warnings errors etc.

No need to import any library:

>>> bytearray.fromhex("7061756c").decode()
'paul'

If you do want to use null values with '=' or '<>' operators you may find the

answer from @egallardo hier

very useful.

Short example for '=': The expression

WHERE t.field = :param

you refactor like this

WHERE ((:param is null and t.field is null) or t.field = :param)

Now you can set the parameter param either to some non-null value or to null:

query.setParameter("param", "Hello World"); // Works
query.setParameter("param", null);          // Works also

This can be done without explicitly using hooks provided you add a prop to your component and a state to the stateless component's parent component:

const ParentComponent = props => {
  const [updateNow, setUpdateNow] = useState(true)

  const updateFunc = () => {
    setUpdateNow(!updateNow)
  }

  const MyComponent = props => {
    return (<div> .... </div>)
  }

  const MyButtonComponent = props => {
    return (<div> <input type="button" onClick={props.updateFunc} />.... </div>)
  }

  return (
    <div> 
      <MyComponent updateMe={updateNow} />
      <MyButtonComponent updateFunc={updateFunc}/>
    </div>
  )
}

tl;dr

For Spark Context you may use:

sc.setLogLevel(<logLevel>)

where loglevel can be ALL, DEBUG, ERROR, FATAL, INFO, OFF, TRACE or WARN.

Details-

Internally, setLogLevel calls org.apache.log4j.Level.toLevel(logLevel) that it then uses to set using org.apache.log4j.LogManager.getRootLogger().setLevel(level).

You may directly set the logging levels to OFF using:

LogManager.getLogger("org").setLevel(Level.OFF)

You can set up the default logging for Spark shell in conf/log4j.properties. Use conf/log4j.properties.template as a starting point.

Setting Log Levels in Spark Applications

In standalone Spark applications or while in Spark Shell session, use the following:

import org.apache.log4j.{Level, Logger}

Logger.getLogger(classOf[RackResolver]).getLevel
Logger.getLogger("org").setLevel(Level.OFF)
Logger.getLogger("akka").setLevel(Level.OFF)

Disabling logging(in log4j):

Use the following in conf/log4j.properties to disable logging completely:

log4j.logger.org=OFF

You'd need attach an onFocus event to the input field via Javascript:

<input type="text" onfocus="this.value=''" value="..." ... />

Adding on to the one mentioned by @abarnert

a better one is to catch the exception

import subprocess
try:
    py2output = subprocess.check_output(['python', 'py2.py', '-i', 'test.txt'],stderr= subprocess.STDOUT)  
    #print('py2 said:', py2output)
    print "here"
except subprocess.CalledProcessError as e:
    print "Calledprocerr"

this stderr= subprocess.STDOUT is for making sure you dont get the filenotfound error in stderr- which cant be usually caught in filenotfoundexception, else you would end up getting

python: can't open file 'py2.py': [Errno 2] No such file or directory

Infact a better solution to this might be to check, whether the file/scripts exist and then to run the file/script

== has higher precedence than &. You might want to wrap your operations in () to specify how you want your operands to bind to the operators.

((a[0] & 1) == 0)

Similarly for all parts of the if condition.

Try the negation operand - 'not'!

Well, if you can perform 'AND' operation on an if statement using nested 'if's (refer previous answers), then you can do the same thing with 'if not' to perform an 'or' operation.

If you haven't got the idea quite as yet, read on. Otherwise, just don't waste your time and get back to programming.

Just as nested 'if's are satisfied only when all conditions are true, nested 'if not's are satisfied only when all conditions are false. This is similar to what you want to do with an 'or' operand, isn't it?

Even when any one of the conditions in the nested 'if not' is true, the whole statement remains non-satisfied. Hence, you can use negated 'if's in succession by remembering that the body of the condition statement should be what you wanna do if all your nested conditions are false. The body that you actually wanted to give should come under the else statement.

And if you still didn't get the jist of the thing, sorry, I'm 16 and that's the best I can do to explain.

Allocate a large map in the beginning. If you know it will have 26 million entries and you have the memory for it, do a new HashMap(30000000).

Are you sure, you have enough memory for 26 million entries with 26 million keys and values? This sounds like a lot memory to me. Are you sure that the garbage collection is doing still fine at your 2 to 3 million mark? I could imagine that as a bottleneck.

In postgres this works very nicely..Tell the server the time at which the time is saved, 'utc', and then ask it to convert to a specific timezone, in this case 'Brazil/East'

quiz_step_progresses.created_at  at time zone 'utc' at time zone 'Brazil/East'

Get a complete list of timezones with the following select;

select * from pg_timezone_names;

See details here.

https://popsql.com/learn-sql/postgresql/how-to-convert-utc-to-local-time-zone-in-postgresql

int total = 0;
protected void gvEmp_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType==DataControlRowType.DataRow)
{
total += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "Amount"));
}
if(e.Row.RowType==DataControlRowType.Footer)
{
Label lblamount = (Label)e.Row.FindControl("lblTotal");
lblamount.Text = total.ToString();
}
}

As an alternative you can also query the information_schema database and retrieve the data from the global_variables (and global_status of course too). This approach provides the same information, but gives you the opportunity to do more with the results, as it is a plain old query.

For example you can convert units to become more readable. The following query provides the current global setting for the innodb_log_buffer_size in bytes and megabytes:

SELECT
  variable_name,
  variable_value AS innodb_log_buffer_size_bytes,
  ROUND(variable_value / (1024*1024)) AS innodb_log_buffer_size_mb
FROM information_schema.global_variables
WHERE variable_name LIKE  'innodb_log_buffer_size';

As a result you get:

+------------------------+------------------------------+---------------------------+
| variable_name          | innodb_log_buffer_size_bytes | innodb_log_buffer_size_mb |
+------------------------+------------------------------+---------------------------+
| INNODB_LOG_BUFFER_SIZE | 268435456                    |                       256 |

I tried both the 32-bit and 64-bit installers of both Oracle and IBM Java on Windows, and the presence of C:\Windows\SysWOW64\java.exe seems to be a reliable way to determine that 32-bit Java is available. I haven't tested older versions of these installers, but this at least looks like it should be a reliable way to test, for the most recent versions of Java.

Referring to Gamaliel 's answer: $args is an array of the arguments that are passed into a script at runtime - as such cannot be used the way Gamaliel is using it. This is actually working:

$myPath = 'C:\whatever.file'

$myAcl = Get-Acl "$myPath"
$myAclEntry = "Domain\User","FullControl","Allow"
$myAccessRule = New-Object System.Security.AccessControl.FileSystemAccessRule($myAclEntry)
# prepare new Acl
$myAcl.SetAccessRule($myAccessRule)
$myAcl | Set-Acl "$MyPath"
# check if added entry present
Get-Acl "$myPath" | fl

• A submodule can be deleted by running git rm <submodule path> && git commit. This can be undone using git revert.
  • The deletion removes the superproject's tracking data, which are both the gitlink entry and the section in the .gitmodules file.
  • The submodule's working directory is removed from the file system, but the Git directory is kept around as it to make it possible to checkout past commits without requiring fetching from another repository.

BundleConfig is nothing more than bundle configuration moved to separate file. It used to be part of app startup code (filters, bundles, routes used to be configured in one class)

To add this file, first you need to add the Microsoft.AspNet.Web.Optimization nuget package to your web project:

Install-Package Microsoft.AspNet.Web.Optimization

Then under the App_Start folder create a new cs file called BundleConfig.cs. Here is what I have in my mine (ASP.NET MVC 5, but it should work with MVC 4):

using System.Web;
using System.Web.Optimization;

namespace CodeRepository.Web
{
    public class BundleConfig
    {
        // For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862
        public static void RegisterBundles(BundleCollection bundles)
        {
            bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                        "~/Scripts/jquery-{version}.js"));

            bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                        "~/Scripts/jquery.validate*"));

            // Use the development version of Modernizr to develop with and learn from. Then, when you're
            // ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                        "~/Scripts/modernizr-*"));

            bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                      "~/Scripts/bootstrap.js",
                      "~/Scripts/respond.js"));

            bundles.Add(new StyleBundle("~/Content/css").Include(
                      "~/Content/bootstrap.css",
                      "~/Content/site.css"));
        }
    }
}

Then modify your Global.asax and add a call to RegisterBundles() in Application_Start():

using System.Web.Optimization;

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

  const navLink = ({match}) => {

    return (

        <Link to={to}>
          {children}
        </Link>
      </li>
    )

  }

  return (
    <Route
      path={typeof to === 'object' ? to.pathname : to}
      exact={exact}
      strict={false}
      children={navLink}
    />
  )
}

Haven't tried it, but Elcomsoft released a product they claim is capable of decrypting backups, for forensics purposes. Maybe not as cool as engineering a solution yourself, but it might be faster.

http://www.elcomsoft.com/eppb.html

You can use

"Hello World ".replace(/\s+/g, '');

trim() only removes trailing spaces on the string (first and last on the chain). In this case this regExp is faster because you can remove one or more spaces at the same time.

If you change the replacement empty string to '$', the difference becomes much clearer:

var string= '  Q  W E   R TY ';
console.log(string.replace(/\s/g, '$'));  // $$Q$$W$E$$$R$TY$
console.log(string.replace(/\s+/g, '#')); // #Q#W#E#R#TY#

Performance comparison - /\s+/g is faster. See here: http://jsperf.com/s-vs-s

For Django versions > 1.10, according to the documentation, a custom MIDDLEWARE can be written as a function, let's say in the file: yourproject/middleware.py (as a sibling of settings.py):

def open_access_middleware(get_response):
    def middleware(request):
        response = get_response(request)
        response["Access-Control-Allow-Origin"] = "*"
        response["Access-Control-Allow-Headers"] = "*"
        return response
    return middleware

and finally, add the python path of this function (w.r.t. the root of your project) to the MIDDLEWARE list in your project's settings.py:

MIDDLEWARE = [
  .
  .
  'django.middleware.clickjacking.XFrameOptionsMiddleware',
  'yourproject.middleware.open_access_middleware'
]

Easy peasy!

jQuery.noop() can help

$(".row").each( function() {
    if (skipIteration) {
        $.noop()
    }
    else{doSomething}
});

Solution: where some_column NOT LIKE '%[^0-9]%' Is correct.

Just one important note: Add validation for when the string column = '' (empty string). This scenario will return that '' is a valid number as well.

Supposing you know when the list data has changed, you can manually tell the list to scroll to the bottom by setting the list selection to the last row. Something like:

private void scrollMyListViewToBottom() {
    myListView.post(new Runnable() {
        @Override
        public void run() {
            // Select the last row so it will scroll into view...
            myListView.setSelection(myListAdapter.getCount() - 1);
        }
    });
}

If you have properly structured your tables so that each contains relatively unique values, then the less intensive way to do this would be to do 3 separate insert-into statements, 1 for each table, with the join-filter in place for each insert -

INSERT INTO SkusBought...

SELECT t1.customer, t1.SKU, t1.TypeDesc
FROM transactiondatatransit AS T1
LEFT OUTER JOIN topThreetransit AS T2
ON t1.customer = t2.customernum
WHERE T2.customernum IS NOT NULL

Repeat this for the other two tables - copy/paste is a fine method, simply change the FROM table name. ** IF you are trying to prevent duplicated entries in your SkusBought table you can add the following join code in each section prior to the WHERE clause.

LEFT OUTER JOIN SkusBought AS T3
ON  t1.customer = t3.customer
AND t1.sku = t3.sku

-and then the last line of WHERE clause-

AND t3.customer IS NULL

Your initial code is using a number of sub-queries, and the UNION statement can be expensive as it will first create its own temporary table to populate the data from the three separate sources before inserting into the table you want ALONG with running another sub-query to filter results.

You can follow uploaded images

Strangely, for me it's SubmitChanges as opposed to SaveChanges:

    foreach (var item in w)
    {
        if (Convert.ToInt32(e.CommandArgument) == item.ID)
        {
            item.Sort = 1;
        }
        else
        {
            item.Sort = null;
        }
        db.SubmitChanges();            
    }                   

There are two problems on our way to the absolute path:

1. The placement found will be not where the source files lie, but where the class is saved. And the resource folder almost surely will lie somewhere in the source folder of the project.
2. The same functions for retrieving the resource work differently if the class runs in a plugin or in a package directly in the workspace.

The following code will give us all useful paths:

    URL localPackage = this.getClass().getResource("");
    URL urlLoader = YourClassName.class.getProtectionDomain().getCodeSource().getLocation();
    String localDir = localPackage.getPath();
    String loaderDir = urlLoader.getPath();
    System.out.printf("loaderDir = %s\n localDir = %s\n", loaderDir, localDir);

Here both functions that can be used for localization of the resource folder are researched. As for class, it can be got in either way, statically or dynamically.

If the project is not in the plugin, the code if run in JUnit, will print:

loaderDir = /C:.../ws/source.dir/target/test-classes/
 localDir = /C:.../ws/source.dir/target/test-classes/package/

So, to get to src/rest/resources we should go up and down the file tree. Both methods can be used. Notice, we can't use getResource(resourceFolderName), for that folder is not in the target folder. Nobody puts resources in the created folders, I hope.

If the class is in the package that is in the plugin, the output of the same test will be:

loaderDir = /C:.../ws/plugin/bin/
 localDir = /C:.../ws/plugin/bin/package/

So, again we should go up and down the folder tree.

The most interesting is the case when the package is launched in the plugin. As JUnit plugin test, for our example. The output is:

loaderDir = /C:.../ws/plugin/
 localDir = /package/

Here we can get the absolute path only combining the results of both functions. And it is not enough. Between them we should put the local path of the place where the classes packages are, relatively to the plugin folder. Probably, you will have to insert something as src or src/test/resource here.

You can insert the code into yours and see the paths that you have.

Update for Java 8 and higher

You can now simply do Instant.parse("2015-04-28T14:23:38.521Z") and get the correct thing now, especially since you should be using Instant instead of the broken java.util.Date with the most recent versions of Java.

You should be using DateTimeFormatter instead of SimpleDateFormatter as well.

Original Answer:

The explanation below is still valid as as what the format represents. But it was written before Java 8 was ubiquitous so it uses the old classes that you should not be using if you are using Java 8 or higher.

This works with the input with the trailing Z as demonstrated:

In the pattern the T is escaped with ' on either side.

The pattern for the Z at the end is actually XXX as documented in the JavaDoc for SimpleDateFormat, it is just not very clear on actually how to use it since Z is the marker for the old TimeZone information as well.

first, you need to delete all old mysql data using

docker-compose down -v

after that add two lines in your docker-compose.yml

volumes:
  - mysql-data:/var/lib/mysql

and

volumes:
  mysql-data:

your final docker-compose.yml will looks like

version: '3.1'

services:
  php:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - 80:80
    volumes:
      - ./src:/var/www/html/
  db:
    image: mysql
    command: --default-authentication-plugin=mysql_native_password
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: example
    volumes:
      - mysql-data:/var/lib/mysql

  adminer:
    image: adminer
    restart: always
    ports:
      - 8080:8080
volumes:
  mysql-data:

after that use this command

docker-compose up -d

now your data will persistent and will not be deleted even after using this command

docker-compose down

extra:- but if you want to delete all data then you will use

docker-compose down -v

TL;DR Check the network mode of your VirtualBox host - it should be bridged if you want the virtual machine (and the Docker container it's hosting) accessible on your local network.

It sounds like your confusion lies in which host to connect to in order to access your application via HTTP. You haven't really spelled out what your configuration is - I'm going to make some guesses, based on the fact that you've got "Windows" and "VirtualBox" in your tags.

I'm guessing that you have Docker running on some flavour of Linux running in VirtualBox on a Windows host. I'm going to label the IP addresses as follows:

D = the IP address of the Docker container

L = the IP address of the Linux host running in VirtualBox

W = the IP address of the Windows host

When you run your Go application on your Windows host, you can connect to it with http://W:8080/ from anywhere on your local network. This works because the Go application binds the port 8080 on the Windows machine and anybody who tries to access port 8080 at the IP address W will get connected.

And here's where it becomes more complicated:

VirtualBox, when it sets up a virtual machine (VM), can configure the network in one of several different modes. I don't remember what all the different options are, but the one you want is bridged. In this mode, VirtualBox connects the virtual machine to your local network as if it were a stand-alone machine on the network, just like any other machine that was plugged in to your network. In bridged mode, the virtual machine appears on your network like any other machine. Other modes set things up differently and the machine will not be visible on your network.

So, assuming you set up networking correctly for the Linux host (bridged), the Linux host will have an IP address on your local network (something like 192.168.0.x) and you will be able to access your Docker container at http://L:8080/.

If the Linux host is set to some mode other than bridged, you might be able to access from the Windows host, but this is going to depend on exactly what mode it's in.

EDIT - based on the comments below, it sounds very much like the situation I've described above is correct.

Let's back up a little: here's how Docker works on my computer (Ubuntu Linux).

Imagine I run the same command you have: docker run -p 8080:8080 dockertest. What this does is start a new container based on the dockertest image and forward (connect) port 8080 on the Linux host (my PC) to port 8080 on the container. Docker sets up it's own internal networking (with its own set of IP addresses) to allow the Docker daemon to communicate and to allow containers to communicate with one another. So basically what you're doing with that -p 8080:8080 is connecting Docker's internal networking with the "external" network - ie. the host's network adapter - on a particular port.

With me so far? OK, now let's take a step back and look at your system. Your machine is running Windows - Docker does not (currently) run on Windows, so the tool you're using has set up a Linux host in a VirtualBox virtual machine. When you do the docker run in your environment, exactly the same thing is happening - port 8080 on the Linux host is connected to port 8080 on the container. The big difference here is that your Windows host is not the Linux host on which the container is running, so there's another layer here and it's communication across this layer where you are running into problems.

What you need is one of two things:

1. to connect port 8080 on the VirtualBox VM to port 8080 on the Windows host, just like you connect the Docker container to the host port.

2. to connect the VirtualBox VM directly to your local network with the bridged network mode I described above.

If you go for the first option, you will be able to access the container at http://W:8080 where W is the IP address or hostname of the Windows host. If you opt for the second, you will be able to access the container at http://L:8080 where L is the IP address or hostname of the Linux VM.

So that's all the higher-level explanation - now you need to figure out how to change the configuration of the VirtualBox VM. And here's where I can't really help you - I don't know what tool you're using to do all this on your Windows machine and I'm not at all familiar with using Docker on Windows.

If you can get to the VirtualBox configuration window, you can make the changes described below. There is also a command line client that will modify VMs, but I'm not familiar with that.

For bridged mode (and this really is the simplest choice), shut down your VM, click the "Settings" button at the top, and change the network mode to bridged, then restart the VM and you're good to go. The VM should pick up an IP address on your local network via DHCP and should be visible to other computers on the network at that IP address.

A free and easy to use service is provided at Webtechriser (click here to read the article) (called wipmania). This one is a JSONP service and requires plain javascript coding with HTML. It can also be used in JQuery. I modified the code a bit to change the output format and this is what I've used and found to be working: (it's the code of my HTML page)

It is worth noting that @Marius's second answer could be used as pure Javascript solution.

document.getElementById('elementId').tagName

I had the same issue as OP (I think!), but I couldn't get it to work in the way that Lastalda specified. I don't know if I have interpreted the question properly, but I have found another solution (it probably is a really bad way of doing it though).

This was the way that I did it:

plt.hist([1,11,21,31,41], bins=[0,10,20,30,40,50], weights=[10,1,40,33,6]);

Which creates this:

So the first parameter basically 'initialises' the bin - I'm specifically creating a number that is in between the range I set in the bins parameter.

To demonstrate this, look at the array in the first parameter ([1,11,21,31,41]) and the 'bins' array in the second parameter ([0,10,20,30,40,50]):

• The number 1 (from the first array) falls between 0 and 10 (in the 'bins' array)
• The number 11 (from the first array) falls between 11 and 20 (in the 'bins' array)
• The number 21 (from the first array) falls between 21 and 30 (in the 'bins' array), etc.

Then I'm using the 'weights' parameter to define the size of each bin. This is the array used for the weights parameter: [10,1,40,33,6].

So the 0 to 10 bin is given the value 10, the 11 to 20 bin is given the value of 1, the 21 to 30 bin is given the value of 40, etc.

I needed both the date and time and used:

mkdir %date%-%time:~0,2%.%time:~3,2%.%time:~6,2%

Which created a folder that looked like: 2018-10-23-17.18.34

The time had to be concatenated because it contained : which is not allowed on Windows.

If you want to set the column you filter on as a new index, you could also consider to use .filter; if you want to keep it as a separate column then str.contains is the way to go.

Let's say you have

df = pd.DataFrame({'vals': [1, 2, 3, 4, 5], 'ids': [u'aball', u'bball', u'cnut', u'fball', 'ballxyz']})

       ids  vals
0    aball     1
1    bball     2
2     cnut     3
3    fball     4
4  ballxyz     5

and your plan is to filter all rows in which ids contains ball AND set ids as new index, you can do

df.set_index('ids').filter(like='ball', axis=0)

which gives

         vals
ids          
aball       1
bball       2
fball       4
ballxyz     5

But filter also allows you to pass a regex, so you could also filter only those rows where the column entry ends with ball. In this case you use

df.set_index('ids').filter(regex='ball$', axis=0)

       vals
ids        
aball     1
bball     2
fball     4

Note that now the entry with ballxyz is not included as it starts with ball and does not end with it.

If you want to get all entries that start with ball you can simple use

df.set_index('ids').filter(regex='^ball', axis=0)

yielding

         vals
ids          
ballxyz     5

The same works with columns; all you then need to change is the axis=0 part. If you filter based on columns, it would be axis=1.

Afer looking at the source, for WP7 Hammock doesn't actually use Json.Net for JSON parsing. Instead it uses it's own parser which doesn't cope with custom types very well.

If using Json.Net directly it is possible to deserialize to a strongly typed collection inside a wrapper object.

var response = @"
    {
        ""data"": [
            {
                ""name"": ""A Jones"",
                ""id"": ""500015763""
            },
            {
                ""name"": ""B Smith"",
                ""id"": ""504986213""
            },
            {
                ""name"": ""C Brown"",
                ""id"": ""509034361""
            }
        ]
    }
";

var des = (MyClass)Newtonsoft.Json.JsonConvert.DeserializeObject(response, typeof(MyClass));

return des.data.Count.ToString();

and with:

public class MyClass
{
    public List<User> data { get; set; }
}

public class User
{
    public string name { get; set; }
    public string id { get; set; }
}

Having to create the extra object with the data property is annoying but that's a consequence of the way the JSON formatted object is constructed.

This seemed far harder to find than it needs to be for OSX. Too many conflicting posts

For MAC OSX Mavericks Java JDK 7, follow these steps to locate keytool:

Firstly make sure to install Java JDK:

http://docs.oracle.com/javase/7/docs/webnotes/install/mac/mac-jdk.html

Then type this into command prompt:

/usr/libexec/java_home -v 1.7

it will spit out something like:

/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home

keytool is located in the same directory as javac. ie:

/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bin

From bin directory you can use the keytool.

select * from global_name;

You can use readlink on /proc/self/fd/NNN where NNN is the file descriptor. This will give you the name of the file as it was when it was opened — however, if the file was moved or deleted since then, it may no longer be accurate (although Linux can track renames in some cases). To verify, stat the filename given and fstat the fd you have, and make sure st_dev and st_ino are the same.

Of course, not all file descriptors refer to files, and for those you'll see some odd text strings, such as pipe:[1538488]. Since all of the real filenames will be absolute paths, you can determine which these are easily enough. Further, as others have noted, files can have multiple hardlinks pointing to them - this will only report the one it was opened with. If you want to find all names for a given file, you'll just have to traverse the entire filesystem.

If you're using T-SQL, the only thing wrong with your code is that you used braces {} instead of parentheses ().

PS: Both IDENTITY and PRIMARY KEY imply NOT NULL, so you can omit that if you wish.

There's a lot of verbosity in here, and I'm deeply against it, so, my conclusive answer would be:

/^\w+$/

\w is equivalent to [A-Za-z0-9_], which is pretty much what you want. (unless we introduce unicode to the mix)

Using the + quantifier you'll match one or more characters. If you want to accept an empty string too, use * instead.

You can adjust the plot margins with plot.margin in theme() and then move your axis labels and title with the vjust argument of element_text(). For example :

library(ggplot2)
library(grid)
qplot(rnorm(100)) +
    ggtitle("Title") +
    theme(axis.title.x=element_text(vjust=-2)) +
    theme(axis.title.y=element_text(angle=90, vjust=-0.5)) +
    theme(plot.title=element_text(size=15, vjust=3)) +
    theme(plot.margin = unit(c(1,1,1,1), "cm"))

will give you something like this :

If you want more informations about the different theme() parameters and their arguments, you can just enter ?theme at the R prompt.

Just simply use this:

String primary_sd = System.getenv("EXTERNAL_STORAGE");
if(primary_sd != null)
    Log.i("EXTERNAL_STORAGE", primary_sd);
String secondary_sd = System.getenv("SECONDARY_STORAGE");
if(secondary_sd != null)
    Log.i("SECONDARY_STORAGE", secondary_sd)

The issue was with the dmp file itself. I had to re-export the file and the command works fine. Thank you @Justin Cave

You're trying to write more data than a specific column can store. Check the sizes of the data you're trying to insert against the sizes of each of the fields.

In this case transaction_status is a varchar(10) and you're trying to store 19 characters to it.

Dynamic Array Example:

Console.WriteLine("Define Array Size? ");
int number = Convert.ToInt32(Console.ReadLine());

Console.WriteLine("Enter numbers:\n");
int[] arr = new int[number];

for (int i = 0; i < number; i++)
{
    arr[i] = Convert.ToInt32(Console.ReadLine());
}
for (int i = 0; i < arr.Length; i++ )
{
    Console.WriteLine("Array Index: "+i + " AND Array Item: " + arr[i].ToString());
}
Console.ReadKey();

A slight adaptation to the solution above by kingjeffrey for when you want to create and echo the CSV within a template (Ie - most frameworks will have output buffering enabled and you are required to set headers etc in controllers.)

// Create Some data
<?php
    $data = array(
        array( 'row_1_col_1', 'row_1_col_2', 'row_1_col_3' ),
        array( 'row_2_col_1', 'row_2_col_2', 'row_2_col_3' ),
        array( 'row_3_col_1', 'row_3_col_2', 'row_3_col_3' ),
    );


// Create a stream opening it with read / write mode
$stream = fopen('data://text/plain,' . "", 'w+');

// Iterate over the data, writting each line to the text stream
foreach ($data as $val) {
    fputcsv($stream, $val);
}

// Rewind the stream
rewind($stream);

// You can now echo it's content
echo stream_get_contents($stream);

// Close the stream 
fclose($stream);

Credit to Kingjeffrey above and also to this blog post where I found the information about creating text streams.

The problem is with slashes: your variable contains them and the final command will be something like sed "s/string/path/to/something/g", containing way too many slashes.

Since sed can take any char as delimiter (without having to declare the new delimiter), you can try using another one that doesn't appear in your replacement string:

replacement="/my/path"
sed --expression "s@pattern@$replacement@"

Note that this is not bullet proof: if the replacement string later contains @ it will break for the same reason, and any backslash sequences like \1 will still be interpreted according to sed rules. Using | as a delimiter is also a nice option as it is similar in readability to /.

You can use the lsof command. Let port number like here is 8090

lsof -i:8090

This command returns a list of open processes on this port.

Something like…

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
ssh 75782 eoin 5u IPv6 0x01c1c234 0t0 TCP localhost:8090 (LISTEN)

To free the port, kill the process using it(the process id is 75782)…

kill -9 75782

This one worked for me. here is the link from the original post: link

You can use /* tslint:disable-next-line */ to locally disable tslint. However, as this is a compiler error disabling tslint might not help.

You can always temporarily cast $ to any:

delete ($ as any).summernote.options.keyMap.pc.TAB

which will allow you to access whatever properties you want.

Edit: As of Typescript 2.6, you can now bypass a compiler error/warning for a specific line:

if (false) {
    // @ts-ignore: Unreachable code error
    console.log("hello");
}

Note that the official docs "recommend you use [this] very sparingly". It is almost always preferable to cast to any instead as that better expresses intent.

std::move itself doesn't really do much. I thought that it called the moved constructor for an object, but it really just performs a type cast (casting an lvalue variable to an rvalue so that the said variable can be passed as an argument to a move constructor or assignment operator).

So std::move is just used as a precursor to using move semantics. Move semantics is essentially an efficient way for dealing with temporary objects.

Consider Object A = B + C + D + E + F;

This is nice looking code, but E + F produces a temporary object. Then D + temp produces another temporary object and so on. In each normal "+" operator of a class, deep copies occur.

For example

Object Object::operator+ (const Object& rhs) {
    Object temp (*this);
    // logic for adding
    return temp;
}

The creation of the temporary object in this function is useless - these temporary objects will be deleted at the end of the line anyway as they go out of scope.

We can rather use move semantics to "plunder" the temporary objects and do something like

 Object& Object::operator+ (Object&& rhs) {
     // logic to modify rhs directly
     return rhs;
 }

This avoids needless deep copies being made. With reference to the example, the only part where deep copying occurs is now E + F. The rest uses move semantics. The move constructor or assignment operator also needs to be implemented to assign the result to A.

Without explicitly defining the height I determined I need to apply the flex value to the parent and grandparent div elements...

<div style="display: flex;">
<div style="display: flex;">
 <img alt="No, he'll be an engineer." src="theknack.png" style="margin: auto;" />
</div>
</div>

If you're using a single element (e.g. dead-centered text in a single flex element) use the following:

align-items: center;
display: flex;
justify-content: center;

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

        $result1 = mysqli_query($connection,$sql1) or die(mysqli_error($connection));

        foreach ($_FILES["file"]["error"] as $key => $error) {

$result = mysqli_query($connection,$query) or die(mysqli_error());


  if($result->num_rows > 0) {
      while($r = mysqli_fetch_assoc($result)){

            $image_name = $row['image'];

I had the exact same error trying to connect via ssh to my server. As I can see you're using a server provided by Hetzner connecting to it on port 22:

debug1: Connecting to xxx.your-server.de [188.40.3.15] port 22.

The offical wiki/documention from Hetzner says:

Protocol for encrypted remote diagnostics for servers/computers(consoles). The SSH port to be used is 222.

So you have to connect via port 222:

ssh -p 222 [email protected]

If you want to keep it simple go ahead and try this out.

$page_number = mysqli_escape_string($con, $_GET['page']);
$count_per_page = 20;
$next_offset = $page_number * $count_per_page;
$cat =mysqli_query($con, "SELECT * FROM categories LIMIT $count_per_page OFFSET $next_offset");
while ($row = mysqli_fetch_array($cat))
        $count = $row[0];

The rest is up to you. If you have result comming from two tables i suggest you try a different approach.

If you don't have permission to link servers, here are the steps to import a table from one server to another using Sql Server Import/Export Wizard:

• Right click on the source database you want to copy from.
• Select Tasks - Export Data.
• Select Sql Server Native Client in the data source.
• Select your authentication type (Sql Server or Windows authentication).
• Select the source database.
• Next, choose the Destination: Sql Server Native Client
• Type in your Server Name (the server you want to copy the table to).
• Select your authentication type (Sql Server or Windows authentication).
• Select the destination database.
• Select Copy data.
• Select your table from the list.
• Hit Next, Select Run immediately, or optionally, you can also save the package to a file or Sql Server if you want to run it later.
• Finish

Others have answered the question, but just for the fun of it, here is a visual dice throwing example, using the Math.random javascript method, a background image and some recursive timeouts.

http://www.jsfiddle.net/zZUgF/3/

Addressing an element of dictionary is like sitting on donkey and enjoy the ride.

As a rule of Python, a DICTIONARY is orderless

If there is

dic = {1: "a", 2: "aa", 3: "aaa"}

Now suppose if I go like dic[10] = "b", then it will not add like this always

dic = {1:"a",2:"aa",3:"aaa",10:"b"}

It may be like

dic = {1: "a", 2: "aa", 3: "aaa", 10: "b"}

Or

dic = {1: "a", 2: "aa", 10: "b", 3: "aaa"}

Or

dic = {1: "a", 10: "b", 2: "aa", 3: "aaa"}

Or any such combination.

So a rule of thumb is that a DICTIONARY is orderless!

I know that it may be not directly answer to your question, because you said that null values have to be supported.

But I just want to note that supporting nulls in compareTo is not in line with compareTo contract described in official javadocs for Comparable:

Note that null is not an instance of any class, and e.compareTo(null) should throw a NullPointerException even though e.equals(null) returns false.

So I would either throw NullPointerException explicitly or just let it be thrown first time when null argument is being dereferenced.

To specify the coordinates within the SVG image independently of the scaled size of the image, use the viewBox attribute on the SVG element to define what the bounding box of the image is in the coordinate system of the image, and use the width and height attributes to define what the width or height are with respect to the containing page.

For instance, if you have the following:

<svg>
    <polygon fill=red stroke-width=0 
             points="0,10 20,10 10,0" />
</svg>

It will render as a 10px by 20px triangle:

Now, if you set only the width and height, that will change the size of the SVG element, but not scale the triangle:

<svg width=100 height=50>
    <polygon fill=red stroke-width=0 
             points="0,10 20,10 10,0" />
</svg>

If you set the view box, that causes it to transform the image such that the given box (in the coordinate system of the image) is scaled up to fit within the given width and height (in the coordinate system of the page). For instance, to scale up the triangle to be 100px by 50px:

<svg width=100 height=50 viewBox="0 0 20 10">
    <polygon fill=red stroke-width=0 
             points="0,10 20,10 10,0" />
</svg>

If you want to scale it up to the width of the HTML viewport:

<svg width="100%" viewBox="0 0 20 10">
    <polygon fill=red stroke-width=0 
             points="0,10 20,10 10,0" />
</svg>

Note that by default, the aspect ratio is preserved. So if you specify that the element should have a width of 100%, but a height of 50px, it will actually only scale up to the height of 50px (unless you have a very narrow window):

<svg width="100%" height="50px" viewBox="0 0 20 10">
    <polygon fill=red stroke-width=0 
             points="0,10 20,10 10,0" />
</svg>

If you actually want it to stretch horizontally, disable aspect ratio preservation with preserveAspectRatio=none:

<svg width="100%" height="50px" viewBox="0 0 20 10" preserveAspectRatio="none">
    <polygon fill=red stroke-width=0 
             points="0,10 20,10 10,0" />
</svg>

(note that while in my examples I use syntax that works for HTML embedding, to include the examples as an image in StackOverflow I am instead embedding within another SVG, so I need to use valid XML syntax)

I've had the same issue. When I was clicking on item's toggle button in my recyclerView checked Toggle button appeared in every 10th item (for example if it was clicked in item with 0 index, items with 9, 18, 27 indexes were getting clicked too). Firstly, my code in onBindViewHolder was:

if (newsItems.get(position).getBookmark() == 1) {
            holder.getToggleButtonBookmark().setChecked(true);
        }

But then I added Else statement

if (newsItems.get(position).getBookmark() == 1) {
            holder.getToggleButtonBookmark().setChecked(true);
//else statement prevents auto toggling
        } else{
            holder.getToggleButtonBookmark().setChecked(false);
        }

And the problem was solved

Update for mid 2016:

The things are changing so fast that if it's late 2017 this answer might not be up to date anymore!

Beginners can quickly get lost in choice of build tools and workflows, but what's most up to date in 2016 is not using Bower, Grunt or Gulp at all! With help of Webpack you can do everything directly in NPM!

• Google "npm as build tool" result: https://medium.com/@dabit3/introduction-to-using-npm-as-a-build-tool-b41076f488b0#.c33e74tsa

• Webpack: https://webpack.github.io/docs/installation.html

Don't get me wrong people use other workflows and I still use GULP in my legacy project(but slowly moving out of it), but this is how it's done in the best companies and developers working in this workflow make a LOT of money!

Look at this template it's a very up-to-date setup consisting of a mixture of the best and the latest technologies: https://github.com/coryhouse/react-slingshot

• Webpack
• NPM as a build tool (no Gulp, Grunt or Bower)
• React with Redux
• ESLint
• the list is long. Go and explore!

Your questions:

When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json

• Everything belongs in package.json now

• Dependencies required for build are in "devDependencies" i.e. npm install require-dir --save-dev (--save-dev updates your package.json by adding an entry to devDependencies)

• Dependencies required for your application during runtime are in "dependencies" i.e. npm install lodash --save (--save updates your package.json by adding an entry to dependencies)

If that is the case, when should I ever install packages explicitly like that without adding them to the file that manages dependencies (apart from installing command line tools globally)?

Always. Just because of comfort. When you add a flag (--save-dev or --save) the file that manages deps (package.json) gets updated automatically. Don't waste time by editing dependencies in it manually. Shortcut for npm install --save-dev package-name is npm i -D package-name and shortcut for npm install --save package-name is npm i -S package-name

Yes, it can be done.
It is based on the new html5 "download" attribute of anchor tags.
The flow should be something like this :

1. load the image
2. draw the image into a canvas with the crop boundaries specified
3. get the image data from the canvas and make it a href attribute for an anchor tag in the dom
4. add the download attribute (download="desired-file-name") to that a element That's it. all the user has to do is click your "download link" and the image will be downloaded to his pc.

I'll come back with a demo when I get the chance.

Update
Here's the live demo as I promised. It takes the jsfiddle logo and crops 5px of each margin.
The code looks like this :

var img = new Image();
img.onload = function(){
    var cropMarginWidth = 5,
        canvas = $('<canvas/>')
                    .attr({
                         width: img.width - 2 * cropMarginWidth,
                         height: img.height - 2 * cropMarginWidth
                     })
                    .hide()
                    .appendTo('body'),
        ctx = canvas.get(0).getContext('2d'),
        a = $('<a download="cropped-image" title="click to download the image" />'),
        cropCoords = {
            topLeft : {
                x : cropMarginWidth,
                y : cropMarginWidth 
            },
            bottomRight :{
                x : img.width - cropMarginWidth,
                y : img.height - cropMarginWidth
            }
        };

    ctx.drawImage(img, cropCoords.topLeft.x, cropCoords.topLeft.y, cropCoords.bottomRight.x, cropCoords.bottomRight.y, 0, 0, img.width, img.height);
    var base64ImageData = canvas.get(0).toDataURL();


    a
        .attr('href', base64ImageData)
        .text('cropped image')
        .appendTo('body');

    a
        .clone()
        .attr('href', img.src)
        .text('original image')
        .attr('download','original-image')
        .appendTo('body');

    canvas.remove();
}
img.src = 'some-image-src';

Update II
Forgot to mention : of course there is a downside :(.
Because of the same-origin policy that is applied to images too, if you want to access an image's data (through the canvas method toDataUrl).
So you would still need a server-side proxy that would serve your image as if it were hosted on your domain.

Update III Although I can't provide a live demo for this (for security reasons), here is a php sample code that solves the same-origin policy :

file proxy.php :

$imgData = getimagesize($_GET['img']);
header("Content-type: " . $imgData['mime']);
echo file_get_contents($_GET['img']);  

This way, instead of loading the external image direct from it's origin :

img.src = 'http://some-domain.com/imagefile.png';

You can load it through your proxy :

img.src = 'proxy.php?img=' + encodeURIComponent('http://some-domain.com/imagefile.png');  

And here's a sample php code for saving the image data (base64) into an actual image :

file save-image.php :

$data = preg_replace('/data:image\/(png|jpg|jpeg|gif|bmp);base64/','',$_POST['data']);
$data = base64_decode($data);
$img = imagecreatefromstring($data);

$path = 'path-to-saved-images/';
// generate random name
$name  = substr(md5(time()),10);
$ext = 'png';
$imageName = $path.$name.'.'.$ext;

// write the image to disk
imagepng($img,  $imageName);
imagedestroy($img);
// return the image path
echo $imageName;

All you have to do then is post the image data to this file and it will save the image to disc and return you the existing image filename.

Of course all this might feel a bit complicated, but I wanted to show you that what you're trying to achieve is possible.

I am doing like this in MSSQL

zip extension is missing, You can avoid this error by simple running below command, It will take version by default

sudo apt-get install php-zip

In case you need any specific version, You need to mention a specific version of your php, Suppose I need to install X version of php-zip then the command will be.

sudo apt-get install phpX-zip  

Replace X with your required version, In my case, it is X = 7.3

The built-in matrix function has the nice option to enter data byrow. Combine that with an unlist on your source list will give you a matrix. We also need to specify the number of rows so it can break up the unlisted data. That is:

> matrix(unlist(a), byrow=TRUE, nrow=length(a) )
      [,1] [,2] [,3] [,4] [,5] [,6]
 [1,]    1    1    2    3    4    5
 [2,]    2    1    2    3    4    5
 [3,]    3    1    2    3    4    5

Happens for me after failed builds run outside of the IDE. If cleaning your workspace doesn't work, try: 1) Delete all projects 2) Close and restart STS/eclipse, 3) Re-import the projects

I had the same exception. The problem was, that I used the annotation

@RepositoryRestController

instead of

@RestController

On Debian, Ubuntu or Linux Mint:

$ sudo apt-get install rubygems ruby-dev

On CentOS, Fedora or RHEL:

$ sudo yum install rubygems ruby-devel

i would suggest the following way:

@PropertySource(ignoreResourceNotFound = true, value = "classpath:otherprops.properties")
@Controller
public class ClassA {
    @Value("${myName}")
    private String name;

    @RequestMapping(value = "/xyz")
    @ResponseBody
    public void getName(){
        System.out.println(name);
    }
}

Here your new properties file name is "otherprops.properties" and the property name is "myName". This is the simplest implementation to access properties file in spring boot version 1.5.8.

try

CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    [CreateTS] [smalldatetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [smalldatetime] NOT NULL

)

PS I think a smalldatetime is good enough. You may decide differently.

Can you not do this at the "moment of impact" ?

In Sql Server, this is common:

Update dbo.MyTable 
Set 

ColA = @SomeValue , 
UpdateDS = CURRENT_TIMESTAMP
Where...........

Sql Server has a "timestamp" datatype.

But it may not be what you think.

Here is a reference:

http://msdn.microsoft.com/en-us/library/ms182776(v=sql.90).aspx

Here is a little RowVersion (synonym for timestamp) example:

CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)


INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Maybe a complete working example:

DROP TABLE [dbo].[Names]
GO


CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)

GO

CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER INSERT, UPDATE
AS

BEGIN

Update dbo.Names Set UpdateTS = CURRENT_TIMESTAMP from dbo.Names myAlias , inserted triggerInsertedTable where 
triggerInsertedTable.Name = myAlias.Name

END


GO






INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Matching on the "Name" value is probably not wise.

Try this more mainstream example with a SurrogateKey

DROP TABLE [dbo].[Names]
GO


CREATE TABLE [dbo].[Names]
(
    SurrogateKey int not null Primary Key Identity (1001,1),
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)

GO

CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER UPDATE
AS

BEGIN

   UPDATE dbo.Names
    SET UpdateTS = CURRENT_TIMESTAMP
    From  dbo.Names myAlias

END


GO






INSERT INTO dbo.Names (Name,UpdateTS)

Strange that noone posted this way:

debug_print_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS);

This actually prints backtrace without the garbage - just what method was called and where.

Check this page out: http://matplotlib.org/examples/pylab_examples/subplots_demo.html

plt.subplots is similar. I think it's better since it's easier to set parameters of the figure. The first two arguments define the layout (in your case 1 row, 2 columns), and other parameters change features such as figure size:

import numpy as np
import matplotlib.pyplot as plt

x1 = np.linspace(0.0, 5.0)
x2 = np.linspace(0.0, 2.0)
y1 = np.cos(2 * np.pi * x1) * np.exp(-x1)
y2 = np.cos(2 * np.pi * x2)

fig, axes = plt.subplots(nrows=1, ncols=2, figsize=(5, 3))
axes[0].plot(x1, y1)
axes[1].plot(x2, y2)
fig.tight_layout()

I ran into this problem when SQL Server 2014 standard was installed on a server where SQL Server Express was also installed. I had opened SSMS from a desktop shortcut, not realizing right away that it was SSMS for SQL Server Express, not for 2014. SSMS for Express returned the error, but SQL Server 2014 did not.

Install and use PHP's GeoIP extension if you can. On debian lenny:

sudo wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
sudo gunzip GeoLiteCity.dat.gz
sudo mkdir -v /usr/share/GeoIP
sudo mv -v GeoLiteCity.dat /usr/share/GeoIP/GeoIPCity.dat

sudo apt-get install php5-geoip
# or sudo apt-get install php-geoip for PHP7

and then try it in PHP:

$ip = $_SERVER['REMOTE_ADDR'];
$country = geoip_country_name_by_name($ip);
echo 'The current user is located in: ' . $country;

returns:

The current user is located in: Cameroon

You could try with OpenNew and then with Write but that's a bit strange use of that class. More info on MSDN.

You have to specify the name of the custom view and its related model in Controller Action method.

public ActionResult About()
{            
   return View("NameOfViewYouWantToReturn",Model); 
}

How about this one? I guess it's not as fancy as the other suggestions because it demands the initial specification of the previous result to produce the expected output, but I feel is a very readable option, i.e., all it does is to provide the result and the previous result to the recursion.

#count the number of recursions
num_rec = 0

def fibonacci(num, prev, num_rec, cycles):

    num_rec = num_rec + 1

    if num == 0 and prev == 0:
        result  = 0;
        num = 1;
    else:
        result = num + prev

    print(result)

    if num_rec == cycles:
        print("done")
    else:
        fibonacci(result, num, num_rec, cycles)

#Run the fibonacci function 10 times
fibonacci(0, 0, num_rec, 10)

Here's the output:

0
1
1
2
3
5
8
13
21
34
done

You can check https://github.com/rajesh38/ng-only-number

1. It restricts input to only numbers and decimal point in a textbox while typing.
2. You can limit the number of digits to be allowed before and after the decimal point
3. It also trims the digits after the decimal point if the decimal point is removed from the textbox e.g. if you have put 123.45 and then remove the decimal point it will also remove the trailing digits after the decimal point and make it 123.

SwiftRichString works perfect! You can use + to concatenate two attributed string

There also is XML schema learner which is available on Github.

It can take multiple xml files and extract a common XSD from all of those files.

Use non-static position along with greater z-index in child element:

.parent {
    position: absolute
    z-index: 100;
}

.child {
    position: relative;
    z-index: 101;
}

For those wondering if jQuery id selectors are slower than document.getElementById, the answer is yes, but not because of the preconception that it searches through the entire DOM looking for an element. jQuery does actually use the native method. It's actually because jQuery uses a regular expression first to separate out strings in the selector to check by, and of course running the constructor:

rquickExpr = /^(?:(<[\w\W]+>)[^>]*|#([\w-]*))$/

Whereas using a DOM element as an argument returns immediately with 'this'.

So this:

$(document.getElementById('blah')).doSomething();

Will always be faster than this:

$('#blah').doSomething();

For EF 4.1,

var objectContext = (myEntities as IObjectContextAdapter).ObjectContext;
objectContext.ExecuteStoreCommand("delete from [myTable];");

First of all, %d is for a int

So %1.16lld makes no sense, because %d is an integer

That typedef you do, is also unnecessary, use the type straight ahead, makes a much more readable code.

What you want to use is the type double, for calculating pi and then using %f or %1.16f.

You cannot set height and width for elements with display:inline;. Use display:inline-block; instead.

From the CSS2 spec:

10.6.1 Inline, non-replaced elements

The height property does not apply. The height of the content area should be based on the font, but this specification does not specify how. A UA may, e.g., use the em-box or the maximum ascender and descender of the font. (The latter would ensure that glyphs with parts above or below the em-box still fall within the content area, but leads to differently sized boxes for different fonts; the former would ensure authors can control background styling relative to the 'line-height', but leads to glyphs painting outside their content area.)

EDIT — You're also missing a ; terminator for the height property:

<div style="display:inline; height:20px width: 70px">My Text Here</div>
<!--                                  ^^ here                       -->

Working example: http://jsfiddle.net/FpqtJ/

thatLine = thatLine.replace('\n', '<br />')

Strings in Python are immutable. You might need to recreate it with the assignment operator.

As others said, class variables are shared between a given class and its subclasses. Class instance variables belong to exactly one class; its subclasses are separate.

Why does this behavior exist? Well, everything in Ruby is an object—even classes. That means that each class has an object of the class Class (or rather, a subclass of Class) corresponding to it. (When you say class Foo, you're really declaring a constant Foo and assigning a class object to it.) And every Ruby object can have instance variables, so class objects can have instance variables, too.

The trouble is, instance variables on class objects don't really behave the way you usually want class variables to behave. You usually want a class variable defined in a superclass to be shared with its subclasses, but that's not how instance variables work—the subclass has its own class object, and that class object has its own instance variables. So they introduced separate class variables with the behavior you're more likely to want.

In other words, class instance variables are sort of an accident of Ruby's design. You probably shouldn't use them unless you specifically know they're what you're looking for.

I got this error message with vs2015, ssdt 14.1.xxx, ssrs. For me I think it was something different than described above with a 2 column, same name problem. I added this report, then deleted the report, then when I tried to add the query back in the ssrs wizard I got this message, " An error occurred while the query design method was being saved :invalid object name: tablename" . where tablename was the table on the query the wizard was reading. I tried cleaning the project, I tried rebuilding the project. In my opinion Microsoft isn't completing cleaning out the report when you delete it and as long as you try to add the original query back it won't add. The way I was able to fix it was to create the ssrs report in a whole new project (obviously nothing wrong with the query) and save it off to the side. Then I reopened my original ssrs project, right clicked on Reports, then Add, then add Existing Item. The report added back in just fine with no name conflict.

I know you asked for Windows but thought I'd add this anyway,in Unix/Linux you could do:

cp `ls -t1 | head -1` /somedir/

Which will list all files in the current directory sorted by modification time and then cp the most recent to /somedir/

If you revise your regular expression like this:

drupal-6.14/(?=sites(?!/all|/default)).*
             ^^

...then it will match all inputs that contain drupal-6.14/ followed by sites followed by anything other than /all or /default. For example:

drupal-6.14/sites/foo
drupal-6.14/sites/bar
drupal-6.14/sitesfoo42
drupal-6.14/sitesall

Changing ?= to ?! to match your original regex simply negates those matches:

drupal-6.14/(?!sites(?!/all|/default)).*
             ^^

So, this simply means that drupal-6.14/ now cannot be followed by sites followed by anything other than /all or /default. So now, these inputs will satisfy the regex:

drupal-6.14/sites/all
drupal-6.14/sites/default
drupal-6.14/sites/all42

But, what may not be obvious from some of the other answers (and possibly your question) is that your regex will also permit other inputs where drupal-6.14/ is followed by anything other than sites as well. For example:

drupal-6.14/foo
drupal-6.14/xsites

Conclusion: So, your regex basically says to include all subdirectories of drupal-6.14 except those subdirectories of sites whose name begins with anything other than all or default.

To get Single/Multiple values without regular expression

// For Single
var value = inputString.Split("<tag1>", '</tag1>')[1];

// For Multiple
var values = inputString.Split("<tag1>", '</tag1>').Where((_, index) => index % 2 != 0);

Declare

public static int[] locations={1,2,3};

outside of the main method.

I had this problem when TortoiseGIT was installed on my machine. After changing the environment variable GIT_SSH from

"c:\Program Files\TortoiseGit\bin\TortoisePlink.exe"

to

"c:\Program Files (x86)\Git\bin\ssh.exe"

and following this tutorial with ssh-keygen and keys:add, it works!

When you install third-party extensions you need to make sure that all the compilation parameters match:

• PHP version
• Architecture (32/64 bits)
• Compiler (VC9, VC10, VC11...)
• Thread safety

Common glitches includes:

• Editing the wrong php.ini file (that's typical with bundles); the right path is shown in phpinfo().
• Forgetting to restart Apache.

• Not being able to see the startup errors; those should show up in Apache logs, but you can also use the command line to diagnose it, e.g.:

  php -d display_startup_errors=1 -d error_reporting=-1 -d display_errors -c "C:\Path\To\php.ini" -m
  

If everything's right you should see sqlsrv in the command output and/or phpinfo() (depending on what SAPI you're configuring):

[PHP Modules]
bcmath
calendar
Core
[...]
SPL
sqlsrv
standard

try {
    LdapContext ctx = new InitialLdapContext(env, null);
    ctx.setRequestControls(null);
    NamingEnumeration<?> namingEnum = ctx.search("ou=people,dc=example,dc=com", "(objectclass=user)", getSimpleSearchControls());
    while (namingEnum.hasMore ()) {
        SearchResult result = (SearchResult) namingEnum.next ();    
        Attributes attrs = result.getAttributes ();
        System.out.println(attrs.get("cn"));

    } 
    namingEnum.close();
} catch (Exception e) {
    e.printStackTrace();
}

private SearchControls getSimpleSearchControls() {
    SearchControls searchControls = new SearchControls();
    searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE);
    searchControls.setTimeLimit(30000);
    //String[] attrIDs = {"objectGUID"};
    //searchControls.setReturningAttributes(attrIDs);
    return searchControls;
}

The Mike R's solution works for me. This is the full set of commands:

Xvfb :99 -ac -screen 0 1280x1024x24 &
export DISPLAY=:99
nice -n 10 x11vnc 2>&1 &

Later you can run google-chrome:

google-chrome --no-sandbox &

Or start google chrome via selenium driver (for example):

ng e2e --serve true --port 4200 --watch true

Protractor.conf file:

capabilities: {
    'browserName': 'chrome',
    'chromeOptions': {
        'args': ['no-sandbox']
    }
},

Don't use CREATE TYPE to return a polymorphic result. Use and abuse the RECORD type instead. Check it out:

CREATE FUNCTION test_ret(a TEXT, b TEXT) RETURNS RECORD AS $$
DECLARE 
  ret RECORD;
BEGIN
  -- Arbitrary expression to change the first parameter
  IF LENGTH(a) < LENGTH(b) THEN
      SELECT TRUE, a || b, 'a shorter than b' INTO ret;
  ELSE
      SELECT FALSE, b || a INTO ret;
  END IF;
RETURN ret;
END;$$ LANGUAGE plpgsql;

Pay attention to the fact that it can optionally return two or three columns depending on the input.

test=> SELECT test_ret('foo','barbaz');
             test_ret             
----------------------------------
 (t,foobarbaz,"a shorter than b")
(1 row)

test=> SELECT test_ret('barbaz','foo');
             test_ret             
----------------------------------
 (f,foobarbaz)
(1 row)

This does wreak havoc on code, so do use a consistent number of columns, but it's ridiculously handy for returning optional error messages with the first parameter returning the success of the operation. Rewritten using a consistent number of columns:

CREATE FUNCTION test_ret(a TEXT, b TEXT) RETURNS RECORD AS $$
DECLARE 
  ret RECORD;
BEGIN
  -- Note the CASTING being done for the 2nd and 3rd elements of the RECORD
  IF LENGTH(a) < LENGTH(b) THEN
      ret := (TRUE, (a || b)::TEXT, 'a shorter than b'::TEXT);
  ELSE
      ret := (FALSE, (b || a)::TEXT, NULL::TEXT);
   END IF;
RETURN ret;
END;$$ LANGUAGE plpgsql;

Almost to epic hotness:

test=> SELECT test_ret('foobar','bar');
   test_ret    
----------------
 (f,barfoobar,)
(1 row)

test=> SELECT test_ret('foo','barbaz');
             test_ret             
----------------------------------
 (t,foobarbaz,"a shorter than b")
(1 row)

But how do you split that out in to multiple rows so that your ORM layer of choice can convert the values in to your language of choice's native data types? The hotness:

test=> SELECT a, b, c FROM test_ret('foo','barbaz') AS (a BOOL, b TEXT, c TEXT);
 a |     b     |        c         
---+-----------+------------------
 t | foobarbaz | a shorter than b
(1 row)

test=> SELECT a, b, c FROM test_ret('foobar','bar') AS (a BOOL, b TEXT, c TEXT);
 a |     b     | c 
---+-----------+---
 f | barfoobar | 
(1 row)

This is one of the coolest and most underused features in PostgreSQL. Please spread the word.

If you are in .NET stack with MVC with AngularJS, this is what you have to do to remove the '#' from url:

1. Set up your base href in your _Layout page: <head> <base href="/"> </head>

2. Then, add following in your angular app config : $locationProvider.html5Mode(true)

3. Above will remove '#' from url but page refresh won't work e.g. if you are in "yoursite.com/about" page refreash will give you a 404. This is because MVC does not know about angular routing and by MVC pattern it will look for a MVC page for 'about' which does not exists in MVC routing path. Workaround for this is to send all MVC page request to a single MVC view and you can do that by adding a route that catches all

url:

routes.MapRoute(
    name: "App",
    url: "{*url}",
    defaults: new {
        controller = "Home", action = "Index"
    }
);

I ran into the same issue, here's my post:

Android Studio - Gradle build failing - Java Heap Space

exec summary: Windows looks for the gradle.properties file here:

C:\Users\.gradle\gradle.properties

So create that file, and add a line like this:

org.gradle.jvmargs=-XX\:MaxHeapSize\=256m -Xmx256m

as per @Faiz Siddiqui post

The item from iterrows() is not a Series, but a tuple of (index, Series), so you can unpack the tuple in the for loop like so:

for (idx, row) in df.iterrows():
    print(row.loc['A'])
    print(row.A)
    print(row.index)

#0.890618586836
#0.890618586836
#Index(['A', 'B', 'C', 'D'], dtype='object')

INSERT INTO Table1 (Column1) VALUES ('John''s')

Or you can use a stored procedure and pass the parameter as -

usp_Proc1 @Column1 = 'John''s'

If you are using an INSERT query and not a stored procedure, you'll have to escape the quote with two quotes, else its OK if you don't do it.

Keep in mind that the copy constructor limits the class type to that of the copy constructor. Consider the example:

// Need to clone person, which is type Person
Person clone = new Person(person);

This doesn't work if person could be a subclass of Person (or if Person is an interface). This is the whole point of clone, is that it can can clone the proper type dynamically at runtime (assuming clone is properly implemented).

Person clone = (Person)person.clone();

or

Person clone = (Person)SomeCloneUtil.clone(person); // See Bozho's answer

Now person can be any type of Person assuming that clone is properly implemented.

No one has mentioned -m option for remote shutdown:

shutdown -r -f -m \\machinename

Also:

• The -r parameter causes a reboot (which is usually what you want on a remote machine, since physically starting it might be difficult).
• The -f parameter option forces the reboot.
• You must have appropriate privileges to shut down the remote machine, of course.

If your file looks like this:

[
    {
        "firstname": "toto",
        "lastname": "titi"
    },
    {
        "firstname": "toto2",
        "lastname": "titi2"
    },
]

You can do:

import json from './json/data.json';
// ....
json.forEach(x => { console.log(x.firstname, x.lastname); });

Strictly speaking; With no Java EE features your app hardly need an appserver at all ;-)

Like others have pointed out JBoss has a (more or less) full Java EE stack while Tomcat is a webcontainer only. JBoss can be configured to only serve as a webcontainer as well, it'd then just be a thin wrapper around the included tomcat webcontainer. That way you could have an almost as lightweight JBoss, which would actually just be a thin "wrapper" around Tomcat. That would be almost as lightweigth.

If you won't need any of the extras JBoss has to offer, go for the one you're most comfortable with. Which is easiest to configure and maintain for you?

Opaque will cause less system strain since 'transparent' will still attempt to apply alpha. The reason you see transparent used instead is because most web authors don't pay attention to detail (ie, just copy-pasted some embed code they found).

BTW, you are correct about it being undocumented. The best I've ever seen is a blog by a guy who claims to have talked to a Macromedia developer about it. Unfortunaetly I can't find the link.

EDIT: I think it was this one: http://www.communitymx.com/content/article.cfm?cid=e5141

simple as this myObj.name = value;

This works for me if you have config and the private key file in the /Jenkins/.ssh/ you need to chown (change owner) for these 2 files then restart jenkins in order for the jenkins instance to read these 2 files.

As long as you have unique integers (or some unique value) in the current PK, you could create a new table, and insert into it with IDENTITY INSERT ON. Then drop the old table, and rename the new table.

Don't forget to recreate any indexes.

In my case I was getting a 404 for glyphicons-halflings-regular.woff, and non visible glyphicons on mobile browsers.

Looks like there is some confusion about the MIME type for woff, more than one MIME type being accepted by different browsers, but the W3C says:

application/font-woff

Edit: After testing the following MIME type for woff works on all browsers currently:

application/x-font-woff

Edit: Latest version of Bootstrap at this time (3.3.5) uses .woff2 fonts with the same initial result as .woff, the W3C still defining the spec but at the moment the MIME type seems to be:

application/font-woff2

The "&" denotes a reference instead of a pointer to an object (In your case a constant reference).

The advantage of having a function such as

foo(string const& myname) 

over

foo(string const* myname)

is that in the former case you are guaranteed that myname is non-null, since C++ does not allow NULL references. Since you are passing by reference, the object is not copied, just like if you were passing a pointer.

Your second example:

const string &GetMethodName() { ... }

Would allow you to return a constant reference to, for example, a member variable. This is useful if you do not wish a copy to be returned, and again be guaranteed that the value returned is non-null. As an example, the following allows you direct, read-only access:

class A
{
  public:
  int bar() const {return someValue;}
  //Big, expensive to copy class
}

class B
{
public:
 A const& getA() { return mA;}
private:
 A mA;
}
void someFunction()
{
 B b = B();
 //Access A, ability to call const functions on A
 //No need to check for null, since reference is guaranteed to be valid.
 int value = b.getA().bar(); 
}

You have to of course be careful to not return invalid references. Compilers will happily compile the following (depending on your warning level and how you treat warnings)

int const& foo() 
{
 int a;

 //This is very bad, returning reference to something on the stack. This will
 //crash at runtime.
 return a; 
}

Basically, it is your responsibility to ensure that whatever you are returning a reference to is actually valid.

I've been downloaded the "SDK ADT Bundle for Windows" adt-bundle-windows-x86.zip to "Documents and settings\myusername\My Documents\Downloads" and tried to unzip to a folder c:\Android

When all seems to be decompressed I saw some files where missing in the destination folder including the eclipse.ini.

I solved this by renaming adt-bundle-windows-x86.zip to a short name adt.zip, moving it to c:\ and repeating the decompression.

All is due to bad treatment of long file-names in windows

In your example, the second return will never happen - the first return is the last thing PHP will run. If you need to return multiple values, return an array:

function test($testvar) {

    return array($var1, $var2);
}

$result = test($testvar);
echo $result[0]; // $var1
echo $result[1]; // $var2

Solution for busybox, macOS bash, and non-bash shells

The accepted answer is certainly the best choice for bash. I'm working in a Busybox environment without access to bash, and it does not understand the exec > >(tee log.txt) syntax. It also does not do exec >$PIPE properly, trying to create an ordinary file with the same name as the named pipe, which fails and hangs.

Hopefully this would be useful to someone else who doesn't have bash.

Also, for anyone using a named pipe, it is safe to rm $PIPE, because that unlinks the pipe from the VFS, but the processes that use it still maintain a reference count on it until they are finished.

Note the use of $* is not necessarily safe.

#!/bin/sh

if [ "$SELF_LOGGING" != "1" ]
then
    # The parent process will enter this branch and set up logging

    # Create a named piped for logging the child's output
    PIPE=tmp.fifo
    mkfifo $PIPE

    # Launch the child process with stdout redirected to the named pipe
    SELF_LOGGING=1 sh $0 $* >$PIPE &

    # Save PID of child process
    PID=$!

    # Launch tee in a separate process
    tee logfile <$PIPE &

    # Unlink $PIPE because the parent process no longer needs it
    rm $PIPE    

    # Wait for child process, which is running the rest of this script
    wait $PID

    # Return the error code from the child process
    exit $?
fi

# The rest of the script goes here

Kotlin code is a lot simpler:

if(isVisable) {
    clearButton.visibility = View.INVISIBLE
}
else {
    clearButton.visibility = View.VISIBLE
}

Try using GET method,

var request = $.ajax({
    url: 'url',
    type: 'GET',
    data: { field1: "hello", field2 : "hello2"} ,
    contentType: 'application/json; charset=utf-8'
});

request.done(function(data) {
      // your success code here
});

request.fail(function(jqXHR, textStatus) {
      // your failure code here
});

You cannot see parameters in URL with POST method.

Edit:

Deprecation Notice: The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks are removed as of jQuery 3.0. You can use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

This function adds all data from object to FormData

http://rreddy.blogspot.com/2009/07/vncviewer-clipboard-operations-like.html

Many times you must have observed that clipboard operations like copy/cut and paste suddenly stops workings with the vncviewer. The main reason for this there is a program called as vncconfig responsible for these clipboard transfers. Some times the program may get closed because of some bug in vnc or some other reasons like you closed that window.

To get those clipboard operations back you need to run the program "vncconfig &".

After this your clipboard actions should work fine with out any problems.

Run "vncconfig &" on the client.

For what it's worth, I've tried both Eigen and Armadillo. Below is a brief evaluation.

Eigen Advantages: 1. Completely self-contained -- no dependence on external BLAS or LAPACK. 2. Documentation decent. 3. Purportedly fast, although I haven't put it to the test.

Disadvantage: The QR algorithm returns just a single matrix, with the R matrix embedded in the upper triangle. No idea where the rest of the matrix comes from, and no Q matrix can be accessed.

Armadillo Advantages: 1. Wide range of decompositions and other functions (including QR). 2. Reasonably fast (uses expression templates), but again, I haven't really pushed it to high dimensions.

Disadvantages: 1. Depends on external BLAS and/or LAPACK for matrix decompositions. 2. Documentation is lacking IMHO (including the specifics wrt LAPACK, other than changing a #define statement).

Would be nice if an open source library were available that is self-contained and straightforward to use. I have run into this same issue for 10 years, and it gets frustrating. At one point, I used GSL for C and wrote C++ wrappers around it, but with modern C++ -- especially using the advantages of expression templates -- we shouldn't have to mess with C in the 21st century. Just my tuppencehapenny.

The above answers unfortunately don't quite work. In particular, the compile stage does not have access to scope, so you can't customize the field based on dynamic attributes. Using the linking stage seems to offer the most flexibility (in terms of asynchronously creating dom, etc.) The below approach addresses that:

<!-- Usage: -->
<form>
  <form-field ng-model="formModel[field.attr]" field="field" ng-repeat="field in fields">
</form>

// directive
angular.module('app')
.directive('formField', function($compile, $parse) {
  return { 
    restrict: 'E', 
    compile: function(element, attrs) {
      var fieldGetter = $parse(attrs.field);

      return function (scope, element, attrs) {
        var template, field, id;
        field = fieldGetter(scope);
        template = '..your dom structure here...'
        element.replaceWith($compile(template)(scope));
      }
    }
  }
})

I've created a gist with more complete code and a writeup of the approach.

The json is kind of odd, it's like the students are properties of the "GetQuestion" object, it should be easy to be a List.....

About the libraries you could use are.

• JavaScriptSerializer
• NewtonSoft.Json
• SimpleJson ...

And there could be many more, but that are what I've used

About the json I don't now maybe something like this

public class GetQuestions
{
    public List<Student> Questions { get; set; }
}

public class Student
{
    public string Code { get; set; }
    public string Questions { get; set; }
}

void Main()
{
    var gq = new GetQuestions
    {
        Questions = new List<Student>
        {
            new Student {Code = "s1", Questions = "Q1,Q2"},
            new Student {Code = "s2", Questions = "Q1,Q2,Q3"},
            new Student {Code = "s3", Questions = "Q1,Q2,Q4"},
            new Student {Code = "s4", Questions = "Q1,Q2,Q5"},
        }
    };

    //Using Newtonsoft.json. Dump is an extension method of [Linqpad][4]
    JsonConvert.SerializeObject(gq).Dump();
}

Linqpad

and the result is this

{
     "Questions":[
        {"Code":"s1","Questions":"Q1,Q2"},
        {"Code":"s2","Questions":"Q1,Q2,Q3"},
        {"Code":"s3","Questions":"Q1,Q2,Q4"},
        {"Code":"s4","Questions":"Q1,Q2,Q5"}
      ]
 }

Yes I know the json is different, but the json that you want with dictionary.

void Main()
{
    var f = new Foo
    {
        GetQuestions = new Dictionary<string, string>
                {
                    {"s1", "Q1,Q2"},
                    {"s2", "Q1,Q2,Q3"},
                    {"s3", "Q1,Q2,Q4"},
                    {"s4", "Q1,Q2,Q4,Q6"},
                }
    };

    JsonConvert.SerializeObject(f).Dump();
}

class Foo
{
    public Dictionary<string, string> GetQuestions { get; set; }
}

And with Dictionary is as you want it.....

{
      "GetQuestions":
       {
              "s1":"Q1,Q2",
              "s2":"Q1,Q2,Q3",
              "s3":"Q1,Q2,Q4",
              "s4":"Q1,Q2,Q4,Q6"
       }
 }

I am not sure since I am not an Oracle user, but I assume that the difference lies when you use multi-byte character sets such as Unicode (UTF-16/32). In this case, 11 Bytes could account for less than 11 characters.

Also those field types might be treated differently in regard to accented characters or case, for example 'binaryField(ete) = "été"' will not match while 'charField(ete) = "été"' might (again not sure about Oracle).

Extension for @Kleist answer:

Since CMake 3.12 additional option CONFIGURE_DEPENDS is supported by commands file(GLOB) and file(GLOB_RECURSE). With this option there is no needs to manually re-run CMake after addition/deletion of a source file in the directory - CMake will be re-run automatically on next building the project.

However, the option CONFIGURE_DEPENDS implies that corresponding directory will be re-checked every time building is requested, so build process would consume more time than without CONFIGURE_DEPENDS.

Even with CONFIGURE_DEPENDS option available CMake documentation still does not recommend using file(GLOB) or file(GLOB_RECURSE) for collect the sources.

A binary tree is made of nodes, where each node contains a "left" pointer, a "right" pointer, and a data element. The "root" pointer points to the topmost node in the tree. The left and right pointers recursively point to smaller "subtrees" on either side. A null pointer represents a binary tree with no elements -- the empty tree. The formal recursive definition is: a binary tree is either empty (represented by a null pointer), or is made of a single node, where the left and right pointers (recursive definition ahead) each point to a binary tree.

A binary search tree (BST) or "ordered binary tree" is a type of binary tree where the nodes are arranged in order: for each node, all elements in its left subtree are less to the node (<), and all the elements in its right subtree are greater than the node (>).

    5
   / \
  3   6 
 / \   \
1   4   9    

The tree shown above is a binary search tree -- the "root" node is a 5, and its left subtree nodes (1, 3, 4) are < 5, and its right subtree nodes (6, 9) are > 5. Recursively, each of the subtrees must also obey the binary search tree constraint: in the (1, 3, 4) subtree, the 3 is the root, the 1 < 3 and 4 > 3.

Watch out for the exact wording in the problems -- a "binary search tree" is different from a "binary tree".

As kmcamara discovered, this is exactly the kind of problem that VLOOKUP is intended to solve, and using vlookup is arguably the simplest of the alternative ways to get the job done.

In addition to the three parameters for lookup_value, table_range to be searched, and the column_index for return values, VLOOKUP takes an optional fourth argument that the Excel documentation calls the "range_lookup".

Expanding on deathApril's explanation, if this argument is set to TRUE (or 1) or omitted, the table range must be sorted in ascending order of the values in the first column of the range for the function to return what would typically be understood to be the "correct" value. Under this default behavior, the function will return a value based upon an exact match, if one is found, or an approximate match if an exact match is not found.

If the match is approximate, the value that is returned by the function will be based on the next largest value that is less than the lookup_value. For example, if "12AT8003" were missing from the table in Sheet 1, the lookup formulas for that value in Sheet 2 would return '2', since "12AT8002" is the largest value in the lookup column of the table range that is less than "12AT8003". (VLOOKUP's default behavior makes perfect sense if, for example, the goal is to look up rates in a tax table.)

However, if the fourth argument is set to FALSE (or 0), VLOOKUP returns a looked-up value only if there is an exact match, and an error value of #N/A if there is not. It is now the usual practice to wrap an exact VLOOKUP in an IFERROR function in order to catch the no-match gracefully. Prior to the introduction of IFERROR, no matches were checked with an IF function using the VLOOKUP formula once to check whether there was a match, and once to return the actual match value.

Though initially harder to master, deusxmach1na's proposed solution is a variation on a powerful set of alternatives to VLOOKUP that can be used to return values for a column or list to the left of the lookup column, expanded to handle cases where an exact match on more than one criterion is needed, or modified to incorporate OR as well as AND match conditions among multiple criteria.

Repeating kcamara's chosen solution, the VLOOKUP formula for this problem would be:

   =VLOOKUP(A1,Sheet1!A$1:B$600,2,FALSE)

Following is the util function to get current timestamp in milliseconds:

#include <sys/time.h>

long long current_timestamp() {
    struct timeval te; 
    gettimeofday(&te, NULL); // get current time
    long long milliseconds = te.tv_sec*1000LL + te.tv_usec/1000; // calculate milliseconds
    // printf("milliseconds: %lld\n", milliseconds);
    return milliseconds;
}

About timezone:

gettimeofday() support to specify timezone, I use NULL, which ignore the timezone, but you can specify a timezone, if need.

@Update - timezone

Since the long representation of time is not relevant to or effected by timezone itself, so setting tz param of gettimeofday() is not necessary, since it won't make any difference.

And, according to man page of gettimeofday(), the use of the timezone structure is obsolete, thus the tz argument should normally be specified as NULL, for details please check the man page.

The answer with "round-tripping" is not exact : when you do

LocalDateTime ldt = LocalDateTime.ofInstant(instant, ZoneOffset.UTC);

if your system timezone is not UTC/GMT, you change the time !

Just go on that directory of your JS file from cmd and write node jsFile.js or even node jsFile; both will work fine.

This is fast & works for whatever length.

public static String prefixZeros(String value, int len) {
    char[] t = new char[len];
    int l = value.length();
    int k = len-l;
    for(int i=0;i<k;i++) { t[i]='0'; }
    value.getChars(0, l, t, k);
    return new String(t);
}

maybe with "and" or "or"

after false need to write "or"

after true need to write "and"

like

n=0
def returnsfalse():
    global n
    n=n+1
    print ("false %d" % (n))
    return False
def returnstrue():
    global n
    n=n+1
    print ("true %d" % (n))
    return True
n=0
returnsfalse() or  returnsfalse() or returnsfalse() or returnstrue() and returnsfalse()

result:

false 1
false 2
false 3
true 4
false 5

or maybe like

(returnsfalse() or true) and (returnstrue() or true) and ...

got here by searching google "how to put multiple statments in one line python", not answers question directly, maybe somebody else needs this.

In Spring STS, Right click the project & select "Open Project", This provision do the necessary action on the background & bring the project back to work space.

In my case, i was not able to see logs because there is some text in Filter field, which caused results of console.log to disappear. Once we clear text in Filter field, it should show.

By using (,), you are capturing the group, if you simply remove them you will not have this problem.

>>> str1 = "a    b     c      d"
>>> re.split(" +", str1)
['a', 'b', 'c', 'd']

However there is no need for regex, str.split without any delimiter specified will split this by whitespace for you. This would be the best way in this case.

>>> str1.split()
['a', 'b', 'c', 'd']

If you really wanted regex you can use this ('\s' represents whitespace and it's clearer):

>>> re.split("\s+", str1)
['a', 'b', 'c', 'd']

or you can find all non-whitespace characters

>>> re.findall(r'\S+',str1)
['a', 'b', 'c', 'd']

I'm assuming you want to store the interestKeys in a list.

Using the org.json library:

JSONObject obj = new JSONObject("{interests : [{interestKey:Dogs}, {interestKey:Cats}]}");

List<String> list = new ArrayList<String>();
JSONArray array = obj.getJSONArray("interests");
for(int i = 0 ; i < array.length() ; i++){
    list.add(array.getJSONObject(i).getString("interestKey"));
}

For case sensitive renaming, git mv somefolder someFolder has worked for me before but didn't today for some reason. So as a workaround I created a new folder temp, moved all the contents of somefolder into temp, deleted somefolder, committed the temp, then created someFolder, moved all the contents of temp into someFolder, deleted temp, committed and pushed someFolder and it worked! Shows up as someFolder in git.

Try this:

@echo off &setlocal
setlocal enabledelayedexpansion

set "search=%1"
set "replace=%2"
set "textfile=Input.txt"
set "newfile=Output.txt"
(for /f "delims=" %%i in (%textfile%) do (
    set "line=%%i"
    set "line=!line:%search%=%replace%!"
    echo(!line!
))>"%newfile%"
del %textfile%
rename %newfile%  %textfile%
endlocal
