Apparently the files were added in remote repository, no matter what was the content of .gitignore file in the origin.

As the files exist in the remote repository, git has to pull them to your local work tree as well and therefore complains that the files already exist.

.gitignore is used only for scanning for the newly added files, it doesn't have anything to do with the files which were already added.

So the solution is to remove the files in your work tree and pull the latest version. Or the long-term solution is to remove the files from the repository if they were added by mistake.

A simple example to remove files from the remote branch is to

$git checkout <brachWithFiles>
$git rm -r *.extension
$git commit -m "fixin...."
$git push

Then you can try the $git merge again

Based on molecular's answer:

DECLARE @F FLOAT = 1000000000.1234;
SELECT @F AS Original, CAST(FORMAT(@F, N'#.##############################') AS VARCHAR) AS Formatted;

SET @F = 823399066925.049
SELECT @F AS Original, CAST(@F AS VARCHAR) AS Formatted
UNION ALL SELECT @F AS Original, CONVERT(VARCHAR(128), @F, 128) AS Formatted
UNION ALL SELECT @F AS Original, CAST(FORMAT(@F, N'G') AS VARCHAR) AS Formatted;

SET @F = 0.502184537571209
SELECT @F AS Original, CAST(@F AS VARCHAR) AS Formatted
UNION ALL SELECT @F AS Original, CONVERT(VARCHAR(128), @F, 128) AS Formatted
UNION ALL SELECT @F AS Original, CAST(FORMAT(@F, N'G') AS VARCHAR) AS Formatted;

I have one tip for you!

I would use:

$('#myModal').on('hidden.bs.modal', function () {
    $('#myModal iframe').removeAttr('src');
})

instead of:

$('#myModal button').click(function () {
    $('#myModal iframe').removeAttr('src');
});

Because you can also close the modal without the button, so there for with this code it will remove the video every time the modal will hide.

If you are using sbt:

//hadoop
lazy val HADOOP_VERSION = "2.8.0"

lazy val dependenceList = Seq(

//hadoop
//The order is important: "hadoop-hdfs" and then "hadoop-common"
"org.apache.hadoop" % "hadoop-hdfs" % HADOOP_VERSION

,"org.apache.hadoop" % "hadoop-common" % HADOOP_VERSION
)

nbextensions ToC instructions

Introduction

As @Ian and @Sergey have mentioned, nbextensions is a simple solution. To elaborate their answer, here is a few more information.

What is nbextensions?

The nbextensions contains a collection of extensions that add functionality to your Jupyter notebook.

For example, just to cite a few extensions:

• Table of Contents

  

• Collapsible headings

  

Install nbextensions

The installation can be done through Conda or PIP

# If conda:
conda install -c conda-forge jupyter_contrib_nbextensions
# or with pip:
pip install jupyter_contrib_nbextensions

You will see the new tab Nbextensions in the jupyter notebook menu. Uncheck the checkbox at the top disable configuration for nbextensions without explicit compatibility (they may break your notebook environment, but can be useful to show for nbextension development) and then check Table of Contents(2). That is all. Screenshot:

Copy js and css files

To copy the nbextensions' javascript and css files into the jupyter server's search directory, do the following:

jupyter contrib nbextension install --user

Toggle extensions

Note that if you are not familiar with the terminal, it would be better to install nbextensions configurator (see the next section)

You can enable/disable the extensions of your choice. As the documentation mentions, the generic command is:

jupyter nbextension enable <nbextension require path>

Concretely, to enable the ToC (Table of Contents) extension, do:

jupyter nbextension enable toc2/main

Install Configuration interface (optional but useful)

As its documentation says, nbextensions_configurator provides config interfaces for nbextensions.

It looks like the following:

To install it if you use conda:

conda install -c conda-forge jupyter_nbextensions_configurator

If you don't have Conda or don't want to install through Conda, then do the following 2 steps:

pip install jupyter_nbextensions_configurator
jupyter nbextensions_configurator enable --user

I just found a solution for jaxrs-ri-2.16 - simply use

String output = response.readEntity(String.class)

this delivers the content as expected.

Building on top of @ReBa's answer above, this custom-border class is what worked for me.

Mods:

• working with border instead of backaground-color since background-color is not consistent.
• Setting height & top of the properties of :after in such a way that the total comes up to 100% where bottom's value is implicit.

To assign value to a single Form control/individually, I propose to use setValue in the following way:

this.editqueForm.get('user').setValue(this.question.user);

this.editqueForm.get('questioning').setValue(this.question.questioning);

file_get_contents() usually has permission issues. To avoid them, use:

function get_xml_from_url($url){
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

    $xmlstr = curl_exec($ch);
    curl_close($ch);

    return $xmlstr;
}

Example:

$xmlstr = get_xml_from_url('http://www.camara.gov.br/SitCamaraWS/Deputados.asmx/ObterDeputados');
$xmlobj = new SimpleXMLElement($xmlstr);
$xmlobj = (array)$xmlobj;//optional

As a bonus, I'd like to offer kind of a different solution to your issue. You seem to be dealing with nested dictionaries, which is usually tedious, especially when you have to check for existence of an inner key.

There are some interesting libraries regarding this on pypi, here is a quick search for you.

In your specific case, dict_digger seems suited.

>>> import dict_digger
>>> d = {
  'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
  'Grapes':{'Arabian':'25','Indian':'20'} 
}

>>> print(dict_digger.dig(d, 'Apple','American'))
16
>>> print(dict_digger.dig(d, 'Grapes','American'))
None

This is the more powerful grouping / rollup syntax you'll want to use in SQL Server 2008+. Always useful to specify the version you're using so we don't have to guess.

SELECT 
  [Type] = COALESCE([Type], 'Total'), 
  [Total Sales] = SUM([Total Sales])
FROM dbo.Before
GROUP BY GROUPING SETS(([Type]),());

Craig Freedman wrote a great blog post introducing GROUPING SETS.

You should initialize yours recordings. You are passing to adapter null

ArrayList<String> recordings = null; //You are passing this null

I think os.environ.copy() is better if you don't intend to modify the os.environ for the current process:

import subprocess, os
my_env = os.environ.copy()
my_env["PATH"] = "/usr/sbin:/sbin:" + my_env["PATH"]
subprocess.Popen(my_command, env=my_env)

The traditional way to flag a method so that it will appear in Interface Builder, and you can drag a connection to it, has been to make the method return type IBAction. However, if you make your method void, instead (IBAction is #define'd to be void), and provide an (id) argument, the method is still visible. This provides extra flexibility, al

All 3 of these are visible from Interface Builder:

-(void) someMethod1:(id) sender; 
-(IBAction) someMethod2; 
-(IBAction) someMethod3:(id) sender;

See Apple's Interface Builder User Guide for details, particularly the section entitled Xcode Integration.

I tried out the filters referenced above and strongly disliked the effect it created. I also didn't want to use any plugins since they'd slow down loading time for what seems like such a basic effect.

In my case I was looking for a text shadow with a 0px blur, which means the shadow is an exact replica of the text but just offset and behind. This effect can be easily recreated with jquery.

<script>
    var shadowText = $(".ie9 .normalText").html();  
    $(".ie9 .normalText").before('<div class="shadow">' + shadowText + '</div>');
</script>
<style>
    .ie9 .shadow { position: relative; top: 2px; left: -3px; }
</style>

This will create an identical effect to the css3 text-shadow below.

    text-shadow: -3px 2px 0px rgba(0, 0, 0, 1.0);

here's a working example (see the large white text over the main banner image) http://www.cb.restaurantconnectinc.com/

Here is a simple minimum script to run from any python console. It assumes that you have extracted the Spark libraries that you have downloaded into C:\Apache\spark-1.6.1.

This works in Windows without building anything and solves problems where Spark would complain about recursive pickling.

import sys
import os
spark_home = 'C:\Apache\spark-1.6.1'

sys.path.insert(0, os.path.join(spark_home, 'python'))
sys.path.insert(0, os.path.join(spark_home, 'python\lib\pyspark.zip')) 
sys.path.insert(0, os.path.join(spark_home, 'python\lib\py4j-0.9-src.zip')) 

# Start a spark context:
sc = pyspark.SparkContext()

# 
lines = sc.textFile(os.path.join(spark_home, "README.md")
pythonLines = lines.filter(lambda line: "Python" in line)
pythonLines.first()

htmlspecialchars() is perfectly adequate for filtering user input that is displayed in html forms.

This one worked for me.

$('#inputName')
  .datepicker()
  .datepicker('setDate', new Date());

in devices which has Android 4.3 and above you should follow these steps:

How to enable Developer Options:

Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.

In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.

A stack in principle is quite simple: imagine a rifle's clip - You can only access the topmost bullet - taking it out is called "pop", inserting a new one is called "push".
A very useful example for that is for applications that allow you to "undo".
Imagine you save each state of the application in a stack. e.g. the state of the application after every type the user makes.
Now when the user presses "undo" you just "pop" the previous state from the stack. For every action the user does - you "push" the new state to the stack (that's of course simplified).

To get this working for Calabash automated tests

There is a pull request up to fix the issue of xcode 12 not working with calabash https://github.com/calabash/run_loop/pull/757

A temporary solution is to use this WIP branch, although it is not great to have to use this as it is a draft PR. Xcode 12 support for Calabash will hopefully come in the future.

Change in your Gemfile

gem "run_loop"

to

gem 'run_loop', git: 'https://github.com/calabash/run_loop.git', branch: 'xcode_14_support'

For anyone who lands here and all the other solutions did not work give this a try. I am using typescript + react and my problem was that I was associating the files in vscode as javascriptreact not typescriptreact so check your settings for the following entries.

   "files.associations": {
    "*.tsx": "typescriptreact",
    "*.ts": "typescriptreact"
  },

You need to use

 $rootScope.$broadcast()

in the controller that must send datas. And in the one that receive those datas, you use

 $scope.$on

Here is a fiddle that i forked a few time ago (I don't know who did it first anymore

http://jsfiddle.net/patxy/RAVFM/

As per official documentation ConfigurationCompat is deprecated in support libraries

You can consider using

LocaleListCompat.getDefault()[0].toLanguageTag() 0th position will be user preferred locale

To get Default locale at 0th position would be LocaleListCompat.getAdjustedDefault()

What happens if the fragment that you want to remove is not on top of the stack?

Then you can use theses functions

popBackStack(int arg0, int arg1);

popBackStack(String arg0, int arg1);

When using matplotlib.pyplot, you must first save your plot and then close it using these 2 lines:

fig.savefig('plot.png') # save the plot, place the path you want to save the figure in quotation
plt.close(fig) # close the figure window

For Linux/Unix:

Simple search for linux utility using following command

netstat -nlp | grep 8888

It'll show processing running at this port, then kill that process using PID (look for a PID in row) of that process.

kill PID

It seems like what you're looking for is a variant on the CSS Holy Grail Layout, but in two columns. Check out the resources at this answer for more information.

You can do this with html/css like this:

    <iframe src="http: //www.google.com.tw" style="position:fixed;top:30px;bottom:0px;width:100%;"></iframe>
</body>

r = ("1"+"2"+"3")           // step1 | build string ==> "123"
r = +r                      // step2 | to number    ==> 123
r = r+100                   // step3 | +100         ==> 223
r = ""+r                    // step4 | to string    ==> "223"

//in one line
r = ""+(+("1"+"2"+"3")+100);

Have you verified that there is in fact a row where Staff_Id = @PersonID? What you've posted works fine in a test script, assuming the row exists. If you comment out the insert statement, then the error is raised.

Found an awesome JavaScript version here: http://oskarhane.com/create-a-nested-array-recursively-in-javascript/

Let’s say you have an array like this:

const models = [
    {id: 1, title: 'hello', parent: 0},
    {id: 2, title: 'hello', parent: 0},
    {id: 3, title: 'hello', parent: 1},
    {id: 4, title: 'hello', parent: 3},
    {id: 5, title: 'hello', parent: 4},
    {id: 6, title: 'hello', parent: 4},
    {id: 7, title: 'hello', parent: 3},
    {id: 8, title: 'hello', parent: 2}
];

And you want to have the objects nested like this:

const nestedStructure = [
    {
        id: 1, title: 'hello', parent: 0, children: [
            {
                id: 3, title: 'hello', parent: 1, children: [
                    {
                        id: 4, title: 'hello', parent: 3, children: [
                            {id: 5, title: 'hello', parent: 4},
                            {id: 6, title: 'hello', parent: 4}
                        ]
                    },
                    {id: 7, title: 'hello', parent: 3}
                ]
            }
        ]
    },
    {
        id: 2, title: 'hello', parent: 0, children: [
            {id: 8, title: 'hello', parent: 2}
        ]
    }
];

Here’s a recursive function that makes it happen.

function getNestedChildren(models, parentId) {
    const nestedTreeStructure = [];
    const length = models.length;

    for (let i = 0; i < length; i++) { // for-loop for perf reasons, huge difference in ie11
        const model = models[i];

        if (model.parent == parentId) {
            const children = getNestedChildren(models, model.id);

            if (children.length > 0) {
                model.children = children;
            }

            nestedTreeStructure.push(model);
        }
    }

    return nestedTreeStructure;
}

Usuage:

const models = [
    {id: 1, title: 'hello', parent: 0},
    {id: 2, title: 'hello', parent: 0},
    {id: 3, title: 'hello', parent: 1},
    {id: 4, title: 'hello', parent: 3},
    {id: 5, title: 'hello', parent: 4},
    {id: 6, title: 'hello', parent: 4},
    {id: 7, title: 'hello', parent: 3},
    {id: 8, title: 'hello', parent: 2}
];
const nestedStructure = getNestedChildren(models, 0);

I have done with this.

The Bootstrap datepicker is able to set date-range. But it is not available in the initial release/Master Branch. Check the branch as 'range' there (or just see at https://github.com/eternicode/bootstrap-datepicker), you can do it simply with startDate and endDate.

Example:

$('#datepicker').datepicker({
    startDate: '-2m',
    endDate: '+2d'
});

I was facing the same issue while i was using JDK 1.8.0_05 64 bit and eclipse-jee-oxygen-3a-win32-x86_64 on Windows 64 bit Operating System.

You should be able to do the following:

$params = @{"@type"="login";
 "username"="[email protected]";
 "password"="yyy";
}

Invoke-WebRequest -Uri http://foobar.com/endpoint -Method POST -Body $params

This will send the post as the body. However - if you want to post this as a Json you might want to be explicit. To post this as a JSON you can specify the ContentType and convert the body to Json by using

Invoke-WebRequest -Uri http://foobar.com/endpoint -Method POST -Body ($params|ConvertTo-Json) -ContentType "application/json"

Extra: You can also use the Invoke-RestMethod for dealing with JSON and REST apis (which will save you some extra lines for de-serializing)

No, abstract class can never be instantiated.

The manual for GNU Make gives a clear definition for all in its list of standard targets.

If the author of the Makefile is following that convention then the target all should:

1. Compile the entire program, but not build documentation.
2. Be the the default target. As in running just make should do the same as make all.

To achieve 1 all is typically defined as a .PHONY target that depends on the executable(s) that form the entire program:

.PHONY : all
all : executable

To achieve 2 all should either be the first target defined in the make file or be assigned as the default goal:

.DEFAULT_GOAL := all

UPDATE:

Like @scottyseus said in the comments, starting from Maven Surefire 2.22.0 the following is sufficient:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.22.1</version>
</plugin>

When using JUnit 5, i ran into the same problem. Maven Surefire needs a plugin to run JUnit 5 tests. Add this to our pom.xml:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.21.0</version>
    <dependencies>
        <dependency>
            <groupId>org.junit.platform</groupId>
            <artifactId>junit-platform-surefire-provider</artifactId>
            <version>1.2.0-M1</version>
        </dependency>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>5.2.0-M1</version>
        </dependency>
    </dependencies>

open your web.xml file. (if you don't know where is it, then just google it.) it is like this:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
.
.
.
.
</web-app>

just below the <?xml version="1.0" encoding="UTF-8"?> line, add a tag <element> and close it in the very bottom with </element> tag. Done.

It is a little bit weird, but it works and IMHO is good readable:

it('should throw Error with message \'UNKNOWN ERROR\' when no parameters were passed', () => {
  try {
      throwError();
      // Fail test if above expression doesn't throw anything.
      expect(true).toBe(false);
  } catch (e) {
      expect(e.message).toBe("UNKNOWN ERROR");
  }
});

The Catch block catches your exception, and then you can test on your raised Error. Strange expect(true).toBe(false); is needed to fail your test if the expected Error will be not thrown. Otherwise, this line is never reachable (Error should be raised before them).

@Kenny Body suggested a better solution which improve a code quality if you use expect.assertions():

it('should throw Error with message \'UNKNOWN ERROR\' when no parameters were passed', () => {
  expect.assertions(1);
  try {
      throwError();
  } catch (e) {
      expect(e.message).toBe("UNKNOWN ERROR");
  }
});

I solved the problem for me by addressing also the worksheet first:

ws.rows(x & ":" & y).Select

without the reference to the worksheet (ws) I got an error.

The GMaps Utility Library has a plugin called MapIconMaker that makes it easy to generate different marker styles on the fly. It uses Google Charts to draw the markers.

There's a good demo here that shows what kind of markers you can make with it.

i use this code for navbar on bootstrap 3.2.0, the image should be at most 50px high, or else it will bleed the standard bs navbar.

Notice that i purposely do not use the class='navbar-brand' as that introduces padding on the image

    <div class="container">
    <!-- Brand and toggle get grouped for better mobile display -->

Online index rebuilds are less intrusive when it comes to locking tables. Offline rebuilds cause heavy locking of tables which can cause significant blocking issues for things that are trying to access the database while the rebuild takes place.

"Table locks are applied for the duration of the index operation [during an offline rebuild]. An offline index operation that creates, rebuilds, or drops a clustered, spatial, or XML index, or rebuilds or drops a nonclustered index, acquires a Schema modification (Sch-M) lock on the table. This prevents all user access to the underlying table for the duration of the operation. An offline index operation that creates a nonclustered index acquires a Shared (S) lock on the table. This prevents updates to the underlying table but allows read operations, such as SELECT statements."

http://msdn.microsoft.com/en-us/library/ms188388(v=sql.110).aspx

Additionally online index rebuilds are a enterprise (or developer) version only feature.

Yes. Look at http://jerrywickey.com/test/testJerrysLibrary.php

It gives sample code examples for RSA encryption and decryption in PHP as well as RSA encryption in javascript.

If you want to encrypt text instead of just base 10 numbers, you'll also need a base to base conversion. That is convert text to a very large number. Text is really just writing in base 63. 26 lowercase letters plus 26 uppercase + 10 numerals + space character. The code for that is below also.

The $GETn parameter is a file name that holds keys for the cryption functions. If you don't figure it out, ask. I'll help.

I actually posted this whole encryption library yesterday, but Brad Larson a mod, killed it and said this kind of stuff isn't really what Stack Overflow is about. But you can still find all the code examples and the whole function library to carry out client/server encryption decryption for AJAX at the link above.

Had the same exception. In my case, I had to run Command Prompt with Administrator Rights.

From the Start Menu, right click on Command Prompt, select "Run as administrator".

While answers that refer to @ModelAttribute, @RequestParam, @PathParam and the likes are valid, there is a small gotcha I ran into. The resulting method parameter is a proxy that Spring wraps around your DTO. So, if you attempt to use it in a context that requires your own custom type, you may get some unexpected results.

The following will not work:

@GetMapping(produces = APPLICATION_JSON_VALUE)
public ResponseEntity<CustomDto> request(@ModelAttribute CustomDto dto) {
    return ResponseEntity.ok(dto);
}

In my case, attempting to use it in Jackson binding resulted in a com.fasterxml.jackson.databind.exc.InvalidDefinitionException.

You will need to create a new object from the dto.

you can use the below command for reset of single file

git checkout HEAD -- path_to_file/file_name

List all changed files to get path_to_file/filename with below command

git status

You can just do this:

long currentTime = (long)(NSTimeInterval)([[NSDate date] timeIntervalSince1970]);

this will return a value en milliseconds, so if you multiply the resulting value by 1000 (as suggested my Eimantas) you'll overflow the long type and it'll result in a negative value.

For example, if I run that code right now, it'll result in

currentTime = 1357234941

and

currentTime /seconds / minutes / hours / days = years
1357234941 / 60 / 60 / 24 / 365 = 43.037637652207

Add to your .gitconfig file next code:

[color]
    ui = auto
[color "branch"]
    current = yellow reverse
    local = yellow
    remote = green
[color "diff"]
    meta = yellow bold
    frag = magenta bold
    old = red bold
    new = green bold
[color "status"]
    added = yellow
    changed = green
    untracked = cyan

<init-param> will be used if you want to initialize some parameter for a particular servlet. When request come to servlet first its init method will be called then doGet/doPost whereas if you want to initialize some variable for whole application you will need to use <context-param> . Every servlet will have access to the context variable.

Here's another solution. this one uses very simple syntax. The first example of the accepted solution did not work on older versions of Microsoft SQL (i.e 2000)

SELECT age, count(*)
FROM Students 
GROUP by age
ORDER BY age

New themes are probably not (yet?) part of the Material Icons font. Link.

In iOS 9.2 they renamed the 'Profiles' to 'Device Management'

This is how you should do it now:

1. Settings -> General -> Device Management
2. Verify the app

I know it's been eight years but I wanted to share this piece of code found in MRuby that shows how __declspec() can bee used at the same level as the export keyword.

/** Declare a public MRuby API function. */
#if defined(MRB_BUILD_AS_DLL)
#if defined(MRB_CORE) || defined(MRB_LIB)
# define MRB_API __declspec(dllexport)
#else
# define MRB_API __declspec(dllimport)
#endif
#else
# define MRB_API extern
#endif

In addition to the other answers, you can use this less-known method to grab elements of a certain parent like so,

$('child', 'parent');

In your case, that would be

if ($(event.target, 'div#hello')[0]) console.log(`${event.target.tagName} is an offspring of div#hello`);

Note the use of commas between the child and parent and their separate quotation marks. If they were surrounded by the same quotes

$('child, parent');

you'd have an object containing both objects, regardless of whether they exist in their document trees.

sudo bash -c "nohup /opt/viptel/viptel_bin/log.sh $* &> /dev/null"  &

Redirecting the output of sudo causes sudo to reask for the password, thus an awkward mechanism is needed to do this variant.

Try calling it like: obj.some_function( '1', 2, '3', g="foo", h="bar" ). After the required positional arguments, you can specify specific optional arguments by name.

Tables work differently; sometimes counter-intuitively.

The solution is to use width on the table cells instead of max-width.

Although it may sound like in that case the cells won't shrink below the given width, they will actually.
with no restrictions on c, if you give the table a width of 70px, the widths of a, b and c will come out as 16, 42 and 12 pixels, respectively.
With a table width of 400 pixels, they behave like you say you expect in your grid above.
Only when you try to give the table too small a size (smaller than a.min+b.min+the content of C) will it fail: then the table itself will be wider than specified.

I made a snippet based on your fiddle, in which I removed all the borders and paddings and border-spacing, so you can measure the widths more accurately.

table {_x000D_
  width: 70px;_x000D_

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:

ffmpeg -i input.mov -qscale 0 output.mp4

Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):

ffmpeg -i input.mov -q:v 0 output.mp4

Whenever you need to resize the textview according to the inside content size, like in messageing app. Use cocoapods(GrowingTextView), it will make your life easier, than coding the dynamic resizing of textview on your own.

To check if variable is null or empty use this:

IF LEN(ISNULL(@var, '')) = 0
    -- Is empty or NULL
ELSE
    -- Is not empty and is not NULL

EXCEPTION
      WHEN DUP_VAL_ON_INDEX

I agree with Shivam's answer except for textract doesn't exist for windows. And, for some reason antiword also fails to read the '.doc' files and gives an error:

'filename.doc' is not a word document. # This happens when the file wasn't generated via MS Office. Eg: Web-pages may be stored in .doc format offline.

So, I've got the following workaround to extract the text:

from bs4 import BeautifulSoup as bs
soup = bs(open(filename).read())
[s.extract() for s in soup(['style', 'script'])]
tmpText = soup.get_text()
text = "".join("".join(tmpText.split('\t')).split('\n')).encode('utf-8').strip()
print text

This script will work with most kinds of files. Have fun!

Yes I think this would be quicker.

Get-ChildItem $folder | Sort-Object -Descending -Property LastWriteTime -Top 1 

Use "\t". That's the tab space character.

You can find a list of many of the Java escape characters here: http://java.sun.com/docs/books/tutorial/java/data/characters.html

Follow these steps:

1. Add path to gitignore file

2. Run this command

   git rm -r --cached foldername
   

3. commit changes as usually.

You can use jsoup to parse any kind of web page. Here you can find the jsoup library and full source code.

Here is an example: http://desicoding.blogspot.com/2011/03/how-to-parse-html-in-java-jsoup.html

To install in Eclipse:

1. Right Click on project
2. BuildPath
3. Add External Archives
4. select the .jar file

You can parse according to tag/parent/child very comfortably

It is quite easy to solve your task. You should create and use a new variable for summing values of the "Doctor Payment" column.

In your case the variable can be declared like this:

<variable name="total" class="java.lang.Integer" calculation="Sum">
    <variableExpression><![CDATA[$F{payment}]]></variableExpression>
</variable>

• the Calculation type is Sum;
• the Reset type is Report;
• the Variable expression is $F{payment}, where $F{payment} is the name of a field contains sum (Doctor Payment).

The working example.

The result will be:

You can find a lot of info in the JasperReports Ultimate Guide.

An alternative that also has the added benefit of easily logging its output:

hexs = "13 00 00 00 08 00"
logging.debug(hexs)
key = bytearray.fromhex(hexs)

allows you to do easy substitutions like so:

hexs = "13 00 00 00 08 {:02X}".format(someByte)
logging.debug(hexs)
key = bytearray.fromhex(hexs)

I would not make the primary key of the "info" table a composite of the two values from other tables.

Others can articulate the reasons better, but it feels wrong to have a column that is really made up of two pieces of information. What if you want to sort on the ID from the second table for some reason? What if you want to count the number of times a value from either table is present?

I would always keep these as two distinct columns. You could use a two-column primay key in mysql ...PRIMARY KEY(id_a, id_b)... but I prefer using a two-column unique index, and having an auto-increment primary key field.

The currently accepted answer does not actually address the question, which asks how to save lists that contain both strings and float numbers. For completeness I provide a fully working example, which is based, with some modifications, on the link given in @joris comment.

import numpy as np

names  = np.array(['NAME_1', 'NAME_2', 'NAME_3'])
floats = np.array([ 0.1234 ,  0.5678 ,  0.9123 ])

ab = np.zeros(names.size, dtype=[('var1', 'U6'), ('var2', float)])
ab['var1'] = names
ab['var2'] = floats

np.savetxt('test.txt', ab, fmt="%10s %10.3f")

Update: This example also works properly in Python 3 by using the 'U6' Unicode string dtype, when creating the ab structured array, instead of the 'S6' byte string. The latter dtype would work in Python 2.7, but would write strings like b'NAME_1' in Python 3.

The differences between Model() and Model.objects.create() are the following:

1. INSERT vs UPDATE

   Model.save() does either INSERT or UPDATE of an object in a DB, while Model.objects.create() does only INSERT.

   Model.save() does

   • UPDATE If the object’s primary key attribute is set to a value that evaluates to True

   • INSERT If the object’s primary key attribute is not set or if the UPDATE didn’t update anything (e.g. if primary key is set to a value that doesn’t exist in the database).

2. Existing primary key

   If primary key attribute is set to a value and such primary key already exists, then Model.save() performs UPDATE, but Model.objects.create() raises IntegrityError.

   Consider the following models.py:

   class Subject(models.Model):
      subject_id = models.PositiveIntegerField(primary_key=True, db_column='subject_id')
      name = models.CharField(max_length=255)
      max_marks = models.PositiveIntegerField()
   

   1. Insert/Update to db with Model.save()

      physics = Subject(subject_id=1, name='Physics', max_marks=100)
      physics.save()
      math = Subject(subject_id=1, name='Math', max_marks=50)  # Case of update
      math.save()
      

      Result:

      Subject.objects.all().values()
      <QuerySet [{'subject_id': 1, 'name': 'Math', 'max_marks': 50}]>
      

   2. Insert to db with Model.objects.create()

      Subject.objects.create(subject_id=1, name='Chemistry', max_marks=100)
      IntegrityError: UNIQUE constraint failed: m****t.subject_id
      

   Explanation: In the example, math.save() does an UPDATE (changes name from Physics to Math, and max_marks from 100 to 50), because subject_id is a primary key and subject_id=1 already exists in the DB. But Subject.objects.create() raises IntegrityError, because, again the primary key subject_id with the value 1 already exists.

3. Forced insert

   Model.save() can be made to behave as Model.objects.create() by using force_insert=True parameter: Model.save(force_insert=True).

4. Return value

   Model.save() return None where Model.objects.create() return model instance i.e. package_name.models.Model

Conclusion: Model.objects.create() does model initialization and performs save() with force_insert=True.

Excerpt from the source code of Model.objects.create()

def create(self, **kwargs):
    """
    Create a new object with the given kwargs, saving it to the database
    and returning the created object.
    """
    obj = self.model(**kwargs)
    self._for_write = True
    obj.save(force_insert=True, using=self.db)
    return obj

The way to do was looking at the code in code/core/Mage/Catalog/Model/Resource/Category/Flat/Collection.php at line 380 in Magento 1.7.2 on the function setPage($pageNum, $pageSize)

 $collection = Mage::getModel('model')
     ->getCollection()
     ->setCurPage(2) // 2nd page
     ->setPageSize(10); // 10 elements per pages

I hope this will help someone.

It is necessary to tell that a Stored Proc is being called:

comm.CommandType = CommandType.StoredProcedure;

In Python 3, print is a function, whereas it used to be a statement in previous versions. As @holdenweb suggested, use 2to3 to translate your code.

You can simply use DataFrame.fillna to fill the nan's directly:

In [27]: df 
Out[27]: 
          A         B         C
0 -0.166919  0.979728 -0.632955

In [28]: df.mean()
Out[28]:

C   -0.530307
dtype: float64

In [29]: df.fillna(df.mean())
Out[29]: 
          A         B         C
0 -0.166919  0.979728 -0.632955

8  1.948430  1.025011 -2.982224
9  0.019698 -0.795876 -0.046431

The docstring of fillna says that value should be a scalar or a dict, however, it seems to work with a Series as well. If you want to pass a dict, you could use df.mean().to_dict().

For SQL Server 2012:

SELECT name, modify_date, create_date, type
FROM sys.procedures
WHERE name like '%XXX%' 
ORDER BY modify_date desc

for resizing my table I went with this solution in my tableview controller witch is perfectly fine:

[objectManager getObjectsAtPath:self.searchURLString
                         parameters:nil
                            success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
                                NSArray* results = [mappingResult array];
                                self.eventArray = results;
                                NSLog(@"Events number at first: %i", [self.eventArray count]);
                                CGRect newFrame = self.activityFeedTableView.frame;
                                newFrame.size.height = self.cellsHeight + 30.0;
                                self.activityFeedTableView.frame = newFrame;

                                self.cellsHeight = 0.0;

                            }
                            failure:^(RKObjectRequestOperation *operation, NSError *error) {
                                UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error"
                                                                                message:[error localizedDescription]
                                                                               delegate:nil
                                                                      cancelButtonTitle:@"OK"
                                                                      otherButtonTitles:nil];
                                [alert show];
                                NSLog(@"Hit error: %@", error);
                            }];

The resizing part is in a method but here is just so you can see it. Now the only problem I haveis resizing the scroll view in the other view controller as I have no idea when the tableview has finished resizing. At the moment I'm doing it with performSelector: afterDelay: but this is really not a good way to do it. Any ideas?

I've not yet tested with large DB but I think this could be faster than joining tables:

SELECT *, Max(Id) FROM messages GROUP BY Name

You can use it to transform some aggregate functions into analytic:

SELECT  MAX(date)
FROM    mytable

will return 1 row with a single maximum,

SELECT  MAX(date) OVER (ORDER BY id)
FROM    mytable

will return all rows with a running maximum.

An alternative crontab method inspired by this answer and this blog post.

1. Create a bash script file (change bob to desired user).

vi /home/bob/node_server_init.sh

2. Copy and paste this inside the file you've just created.

#!/bin/sh

export NODE_ENV=production
export PATH=/usr/local/bin:$PATH
forever start /node/server/path/server.js > /dev/null

Make sure to edit the paths above according to your config!

3. Make sure the bash script can be executed.

chmod 700 /home/bob/node_server_init.sh

4. Test the bash script.

sh /home/bob/node_server_init.sh

5. Replace "bob" with the runtime user for node.

crontab -u bob -e

6. Copy and paste (change bob to desired user).

@reboot /bin/sh /home/bob/node_server_init.sh

Save the crontab.

You've made it to the end, your prize is a reboot (to test) :)

The answer by @GordonM is good. But it would fail if the $string is already true (ie, the string isn't a string but boolean TRUE)...which seems illogical.

Extending his answer, I'd use:

$test_mode_mail = ($string === 'true' OR $string === true));

Internally, Javascript strings are all Unicode (actually UCS-2, a subset of UTF-16).

If you're retrieving the JSON files separately via AJAX, then you only need to make sure that the JSON files are served with the correct Content-Type and charset: Content-Type: application/json; charset="utf-8"). If you do that, jQuery should already have interpreted them properly by the time you access the deserialized objects.

Could you post an example of the code you’re using to retrieve the JSON objects?

String.split seems to be much slower than StringTokenizer. The only advantage with split is that you get an array of the tokens. Also you can use any regular expressions in split. org.apache.commons.lang.StringUtils has a split method which works much more faster than any of two viz. StringTokenizer or String.split. But the CPU utilization for all the three is nearly the same. So we also need a method which is less CPU intensive, which I am still not able to find.

Switching from gcc 4.6 to gcc 4.8 resolved this for me.

I have following solution and it worked for me.

Whenever login page is requested, write the referer value to the session:

@RequestMapping(value="/login", method = RequestMethod.GET)
public String login(ModelMap model,HttpServletRequest request) {

    String referrer = request.getHeader("Referer");
    if(referrer!=null){
        request.getSession().setAttribute("url_prior_login", referrer);
    }
    return "user/login";
}

Then, after successful login custom implementation of SavedRequestAwareAuthenticationSuccessHandler will redirect user to the previous page:

HttpSession session = request.getSession(false);
if (session != null) {
    url = (String) request.getSession().getAttribute("url_prior_login");
}

Redirect the user:

if (url != null) {
    response.sendRedirect(url);
}

127.0.0.1 is normally the IP address assigned to the "loopback" or local-only interface. This is a "fake" network adapter that can only communicate within the same host. It's often used when you want a network-capable application to only serve clients on the same host. A process that is listening on 127.0.0.1 for connections will only receive local connections on that socket.

"localhost" is normally the hostname for the 127.0.0.1 IP address. It's usually set in /etc/hosts (or the Windows equivalent named "hosts" somewhere under %WINDIR%). You can use it just like any other hostname - try "ping localhost" to see how it resolves to 127.0.0.1.

0.0.0.0 has a couple of different meanings, but in this context, when a server is told to listen on 0.0.0.0 that means "listen on every available network interface". The loopback adapter with IP address 127.0.0.1 from the perspective of the server process looks just like any other network adapter on the machine, so a server told to listen on 0.0.0.0 will accept connections on that interface too.

That hopefully answers the IP side of your question. I'm not familiar with Jekyll or Vagrant, but I'm guessing that your port forwarding 8080 => 4000 is somehow bound to a particular network adapter, so it isn't in the path when you connect locally to 127.0.0.1

Few years later, want to suggest just for this: https://github.com/casey/just

action v1 v2=default:
    @echo 'take action on {{v1}} and {{v2}}...'

While I agree that in general inline-block is better, there's one extra thing to take into account if you're using percentage widths to create a responsive grid (or if you want pixel-perfect widths):

If you're using inline-block for grids that total 100% or near to 100% width, you need to make sure your HTML markup contains no white space between columns.

With floats, this is not something you need to worry about - the columns float over any whitespace or other content between columns. This question's answers have some good tips on ways to remove HTML whitespace without making your code ugly.

If for any reason you can't control the HTML markup (e.g. a restrictive CMS), you can try the tricks described here, or you might need to compromise and use floats instead of inline-block. There are also ugly CSS tricks that should only be used in extreme circumstances, like font-size:0; on the column container then reapply font size within each column.

For example:

• Here's a 3-column grid of 33.3% width with float: left. It "just works" (but for the wrapper needing to be cleared).
• Here's the exact same grid, with inline-block. The whitespace between blocks creates a fixed-width space which pushes the total width beyond 100%, breaking the layout and causing the last column to drop down a line.
• Here' s the same grid, with inline-block and no whitespace between columns in the HTML. It "just works" again - but the HTML is uglier and your CMS might force some kind of prettification or indenting to its HTML output making this difficult to achieve in reality.

go to python/scripts folder, open a command window to this path, type the following:

C:\python34\scripts> python -m pip install pygame

To test it, open python IDE and type

import pygame

print (pygame.ver)

It worked for me...

You need the :not() selector:

$('div[class^="first-"]:not(.first-bar)')

or, alternatively, the .not() method:

$('div[class^="first-"]').not('.first-bar');

In cell A1, enter the time.
In cell B2, enter =A1+1/24

&& is new in C++11. int&& a means "a" is an r-value reference. && is normally only used to declare a parameter of a function. And it only takes a r-value expression. If you don't know what an r-value is, the simple explanation is that it doesn't have a memory address. E.g. the number 6, and character 'v' are both r-values. int a, a is an l-value, however (a+2) is an r-value. For example:

void foo(int&& a)
{
    //Some magical code...
}

int main()
{
    int b;
    foo(b); //Error. An rValue reference cannot be pointed to a lValue.
    foo(5); //Compiles with no error.
    foo(b+3); //Compiles with no error.

    int&& c = b; //Error. An rValue reference cannot be pointed to a lValue.
    int&& d = 5; //Compiles with no error.
}

Hope that is informative.

Any element can have a class or an id.

A class is used to reference a certain type of display, for example you may have a css class for a div that represents the answer to this question. As there will be many answers, multiple divs would need the same styling and you would use a class.

An id refers to only a single element, for example the related section at the right may have styling specific to it not reused elsewhere, it would use an id.

Technically you can use classes for all of it, or split them up logically. You can not, however, reuse id's for multiple elements.

I used pdf unite on the linux terminal by leveraging subprocess (assumes one.pdf and two.pdf exist on the directory) and the aim is to merge them to three.pdf

 import subprocess
 subprocess.call(['pdfunite one.pdf two.pdf three.pdf'],shell=True)

There is one other possible way, and the one that I like best. Basically it's the same way lightbox disables a whole page, by placing a div and fiddling with z-index. Here is relevant snippets from a project of mine. This works in all browsers!!!!!

Javascript (jQuery):

var windowResizer = function(){
        var offset = $('#back').offset();   
        var buttontop = offset.top;
        var buttonleft = offset.left;
        $('#backdisabler').css({'top':buttontop,'left':buttonleft,'visibility':'visible'});
        offset = $('#next').offset();
        buttontop = offset.top;
        buttonleft = offset.left;
        $('#nextdisabler').css({'top':buttontop,'left':buttonleft,'visibility':'visible'});
}

$(document).ready(function() {
    $(window).resize(function() {   
        setTimeout(function() {
            windowResizer();
        }, 5); //when the maximize/restore buttons are pressed, we have to wait or it will fire to fast
    });
});

and in html

<a href="" id="back" style="float: left"><img src="images/icons/back.png" style="height: 50px; width: 50px" /></a>
<a href="" id="next" style="float: right"><img src="images/icons/next.png" style="height: 50px; width: 50px" /></a>
<img id="backdisabler" src="images/icons/disabled.png" style="visibility: hidden; position: absolute; padding: 5px; height: 62px; width: 62px; z-index: 9000"/>
<img id="nextdisabler" src="images/icons/disabled.png" style="visibility: hidden; position: absolute; padding: 5px; height: 62px; width: 62px; z-index: 9000"/>

So the resizer finds the anchor's (the images are just arrows) locations and places the disabler on top. The disabler's image is a translucent grey square (change the width/height of the disablers in the html to match your link) to show that it is disabled. The floating allows the page to resize dynamically, and the disablers will follow suit in windowResizer(). You can find suitable images through google. I have placed the relevant css inline for simplicity.

then based on some condition,

$('#backdisabler').css({'visibility':'hidden'});
$('#nextdisabler').css({'visibility':'visible'});

This is because the script is not in your $PATH. Use

./scriptname

You can also copy this to one of the folders in your $PATH or alter the $PATH variable so you can always use just the script name. Take care, however, there is a reason why your current folder is not in $PATH. It might be a security risk.

If you still have problems executing the script, you might want to check its permissions - you must have execute permissions to execute it, obviously. Use

chmod u+x scriptname

A .sh file is a Unix shell script. A .bat file is a Windows batch file.

I did it this way, where 'struts2ActionName' is the struts2 action in my case. You may use any url instead.

var urlAdditionCert =${pageContext.request.contextPath}/struts2ActionName";
$("#dialogId").load( urlAdditionCert).dialog({
    modal: true,
    height: $("#body").height(),
    width: $("#body").width()*.8
});

In Windows, you can execute the pip module by mentioning the python version ( You need to ensure that the launcher is on your path )

Old question, but this is what I typically do to make things a bit more readable:

Func<int, string, Tuple<int, string>> tc = Tuple.Create;

var tupleList = new List<Tuple<int, string>>
{
    tc( 1, "cow" ),
    tc( 5, "chickens" ),
    tc( 1, "airplane" )
};

Note that in an attribute selector (e.g., [attr~=value]), the tilde

Represents an element with an attribute name of attr whose value is a whitespace-separated list of words, one of which is exactly value.

Given the following tables..

Domain Table
dom_id | dom_url

Review Table
rev_id | rev_dom_from | rev_dom_for

Try this sql... (It's pretty much the same thing that Stephen Wrighton wrote above) The trick is that you are basically selecting from the domain table twice in the same query and joining the results.

I came to this post because I had the same error.

In my case the database evolutions weren't been executed, so the table wasn't there at all.

My problem was that the folder structure for the evolution scripts was wrong.

from: https://www.playframework.com/documentation/2.0/Evolutions

Play tracks your database evolutions using several evolutions script. These scripts are written in plain old SQL and should be located in the conf/evolutions/{database name} directory of your application. If the evolutions apply to your default database, this path is conf/evolutions/default.

I had a folder called conf/evolutions.default created by eclipse. The issue disappeared after I corrected the folder structure to conf/evolutions/default

Gson allows for one of the simplest possible solutions. Compared to similar APIs like Jackson or svenson, Gson by default doesn't even need the unused JSON elements to have bindings available in the Java structure. Specific to the question asked, here's a working solution.

import com.google.gson.Gson;

public class Foo
{
  static String jsonInput = 
    "{" + 
      "\"name\":\"John\"," + 
      "\"age\":\"20\"," + 
      "\"address\":\"some address\"," + 
      "\"someobject\":" +
      "{" + 
        "\"field\":\"value\"" + 
      "}" + 
    "}";

  String age;

  public static void main(String[] args) throws Exception
  {
    Gson gson = new Gson();
    Foo thing = gson.fromJson(jsonInput, Foo.class);
    if (thing.age != null)
    {
      System.out.println("age is " + thing.age);
    }
    else
    {
      System.out.println("age element not present or value is null");
    }
  }
}

Type npm list graceful-fs and you will see which versions of graceful-fs are currently installed.

In my case I got:

npm list graceful-fs

As you can see gulp deep down depends on a very old version. Unfortunately, I can't update that myself using npm update graceful-fs. gulp would need to update their dependencies. So if you have a case like this you are out of luck. But you may open an issue for the project with the old dependency - i.e. gulp.

Just replace the first line with the below;

SqlConnection con = new SqlConnection("Server=localhost;Database=employeedetails;Trusted_Connection=True");

You are facing a double-encoding issue.

¦ and • are absolutely equivalent to each other. Both refer to the Unicode character 'BULLET' (U+2022) and can exist side-by-side in HTML source code.

However, if that source-code is HTML-encoded again at some point, it will contain ¦ and •. The former is rendered unchanged, the latter will come out as "•" on the screen.

This is correct behavior under these circumstances. You need to find the point where the superfluous second HTML-encoding occurs and get rid of it.

Directly from ngStyle docs:

Expression which evals to an object whose keys are CSS style names and values are corresponding values for those CSS keys.

<div ng-style="{'width': '20px', 'height': '20px', ...}"></div>

So you could do this:

<div ng-style="{'background-color': data.backgroundCol}"></div>

Hope this helps!

Easier procedure on latest versions:

• Copy jar to libs directory in the app (you can create the directory it if not there)
• Refresh project so libs show up in the structure (right click on project top level, refresh/synchronize)
• Expand libs and right click on the jar
• Select "Add as Library"

Done

easiest way to append class name using javascript. It can be useful when .siblings() are misbehaving.

document.getElementById('myId').className += ' active';

What I found !!!, In tables CSS td{height:60px;} works same as CSS td{min-height:60px;}

I know that situation when cells height looks bad . This javascript solution don't need overflow hidden.

For Limiting max-height of all cells or rows in table with Javascript:

This script is good for horizontal overflow tables.

This script increase the table width 300px each time (maximum 4000px) until rows shrinks to max-height(160px) , and you can also edit numbers as your need.

var i = 0, row, table = document.getElementsByTagName('table')[0], j = table.offsetWidth;
while (row = table.rows[i++]) {
    while (row.offsetHeight > 160 && j < 4000) {
        j += 300;
        table.style.width = j + 'px';
    }
}

For Eclipse: menu bar-> window -> show view then find "debug" option if not in list then select other ...

new window will open and then search using keyword "debug" -> select debug from list

it will added near console tab. use debug tab to terminate and remove previous executions. ( right clicking on executing process will show you many option including terminate)

I have found the creates option in the command module useful. How about this:

- name: Move foo to bar
  command: creates="path/to/bar" mv /path/to/foo /path/to/bar

I used to do a 2 task approach using stat like Bruce P suggests. Now I do this as one task with creates. I think this is a lot clearer.

If you using formview or something similar you can databind the gridview on the iteminserted event of the formview too. Like below

protected void FormView1_ItemInserted(object sender, FormViewInsertedEventArgs e)
    {
        GridView1.DataBind();
    }

You can do this on the data source iteminserted too.

$servername = "";
$username = "";
$password = "";
$database = "";
$port = "1433";
try {
    $conn = new PDO("sqlsrv:server=$servername,$port;Database=$database;ConnectionPooling=0", $username, $password,
        array(
            PDO::ATTR_PERSISTENT => true,
            PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
        )
    );
} catch (PDOException $e) {
    echo ("Error connecting to SQL Server: " . $e->getMessage());
}

May be simpler than the simplest one above:

>>> a = ["foo", "bar"]
>>> b = [1, 2, 3]
>>> [(x,y) for x in a for y in b]  # for a list
[('foo', 1), ('foo', 2), ('foo', 3), ('bar', 1), ('bar', 2), ('bar', 3)]
>>> ((x,y) for x in a for y in b)  # for a generator if you worry about memory or time complexity.
<generator object <genexpr> at 0x1048de850>

For some reason [IgnoreDataMember] does not always work for me, and I sometimes get StackOverflowException (or similar). So instead (or in addition) i've started using a pattern looking something like this when POSTing in Objects to my API:

[Route("api/myroute")]
[AcceptVerbs("POST")]
public IHttpActionResult PostMyObject(JObject myObject)
{
    MyObject myObjectConverted = myObject.ToObject<MyObject>();

    //Do some stuff with the object

    return Ok(myObjectConverted);
}

So basically i pass in an JObject and convert it after it has been recieved to aviod problems caused by the built-in serializer that sometimes cause an infinite loop while parsing the objects.

If someone know a reason that this is in any way a bad idea, please let me know.

It may be worth noting that it is the following code for an EntityFramework Class-property that causes the problem (If two classes refer to each-other):

[Serializable]
public partial class MyObject
{
   [IgnoreDataMember]
   public MyOtherObject MyOtherObject => MyOtherObject.GetById(MyOtherObjectId);
}

[Serializable]
public partial class MyOtherObject
{
   [IgnoreDataMember]
   public List<MyObject> MyObjects => MyObject.GetByMyOtherObjectId(Id);
}

And if you mean select the ID of the last record inserted, its

SELECT @@IDENTITY FROM table

This does the trick:

function findAncestor (el, cls) {
    while ((el = el.parentElement) && !el.classList.contains(cls));
    return el;
}

The while loop waits until el has the desired class, and it sets el to el's parent every iteration so in the end, you have the ancestor with that class or null.

Here's a fiddle, if anyone wants to improve it. It won't work on old browsers (i.e. IE); see this compatibility table for classList. parentElement is used here because parentNode would involve more work to make sure that the node is an element.

SELECT * INTO newtable
from Oldtable

var list = new List<string>();
var queryable = list.AsQueryable();

Add a reference to: System.Linq

The easiest solution I found, is given on python.org devguide:

sudo apt-get build-dep python3.6

If that package is not available for your system, try reducing the minor version until you find a package that is available in your system’s package manager.

I tried explaining details, on my blog.

You can test like this:

create table test1(
 id number,
 name varchar2(20)
);

insert into test1 values (1,'abc');
insert into test1 values (1,'abc');

select * from test1;
select count(*) from test1;
select count(1) from test1;
select count(ALL 1) from test1;
select count(DISTINCT 1) from test1;

I had a similar issue to this. I solved it by making all the projects within my solution target the same .NET Framework 4 Client Profile and then rebuilding the entire solution.

Use loggers and print statements in the Development Environment, you can go for sentry in case of production environments.

just want to share, i've played around with the viewport settings for my responsive design, if i set the Max scale to 0.8, the initial scale to 1 and scalable to no then i get the smallest view in portrait mode and the iPad view for landscape :D... this is properly an ugly hack but it seems to work, i don't know why so i won't be using it, but interesting results

<meta name="viewport" content="user-scalable=no, initial-scale = 1.0,maximum-scale = 0.8,width=device-width" />

enjoy :)

You can try this:

pushd ../
maven install [...]
popd

You have three options:

• Use another way to get the file on the server, and use a mysql client on the server
• Use another client to connect to the server and load the data
• Change your PHP settings to allow such huge files. Don't forget to increment the execution time as well.

There is no show event in js - you need to bind your button either to the click event:

$('#id').on('click', function (e) {

     //your awesome code here

})

Mind that if your button is inside a form, you may prefer to bind the whole form to the submit event.

You can use the code below.

String strFilter = "_id=" + Id;
ContentValues args = new ContentValues();
args.put(KEY_TITLE, title);
myDB.update("titles", args, strFilter, null);

That's invalid Javascript syntax; a property name cannot have a -.

Use either zIndex or "z-index".

Now, there is gcc-4.9 available for Ubuntu/precise.

Create a group of compiler alternatives where the distro compiler has a higher priority:

root$ VER=4.6 ; PRIO=60
root$ update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-$VER $PRIO --slave /usr/bin/g++ g++ /usr/bin/g++-$VER
root$ update-alternatives --install /usr/bin/cpp cpp-bin /usr/bin/cpp-$VER $PRIO

root$ VER=4.9 ; PRIO=40
root$ update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-$VER $PRIO --slave /usr/bin/g++ g++ /usr/bin/g++-$VER
root$ update-alternatives --install /usr/bin/cpp cpp-bin /usr/bin/cpp-$VER $PRIO

NOTE: g++ version is changed automatically with a gcc version switch. cpp-bin has to be done separately as there exists a "cpp" master alternative.

List available compiler alternatives:

root$ update-alternatives --list gcc
root$ update-alternatives --list cpp-bin

To select manually version 4.9 of gcc, g++ and cpp, do:

root$ update-alternatives --config gcc
root$ update-alternatives --config cpp-bin

Check compiler versions:

root$ for i in gcc g++ cpp ; do $i --version ; done

Restore distro compiler settings (here: back to v4.6):

root$ update-alternatives --auto gcc
root$ update-alternatives --auto cpp-bin

You have to add the row explicitly to the table

table.Rows.Add(row);

To completely detail out the summary of all the above answers.

Reason

This problem is occuring because git cannot complete the https handshake with the git server were the repository you are trying to access is present.

Solution

Steps to get the certificate from the github server

1. Open the github you are trying to access in the browser
2. Press on the lock icon in the address bar > click on 'certicicate'
3. Go to 'Certification Path' tab > select the top most node in the heirarchy of certifcates > click on 'view certificate'
4. Now click on 'Details' and click on 'Copy to File..' > Click 'Next' > Select 'Base 64 encoded X509 (.CER)' > save it to any of your desired path.

Steps to add the certificate to local git certificate store

1. Now open the certicate you saved in the notepad and copy the content along with --Begin Certificate-- and --end certificate--

2. To find the path were all the certificates are stored for your git, execute the following command in cmd.

   git config --list

3. Check for the key 'http.sslcainfo', the correspondig value will be path.

4. Now open 'ca-bundle.crt' present in that path.

Note 1 : open this file administrator mode otherwise you will not be able to save it after update. (Tip - you can use Notepad++ for this purpose)

Note 2 : Before modifying this file please keep a backup elsewhere.

5. Now copy the contents of file mentioned in step 1 to the file in step 4 at end file, like how other certificates are placed in ca-bundle.crt.
6. Now open a new terminal and now you should be able to perform opertions related to the git server using https.

You can use groups (indicated with '(' and ')') to capture parts of the string. The match object's group() method then gives you the group's contents:

>>> import re
>>> s = 'name my_user_name is valid'
>>> match = re.search('name (.*) is valid', s)
>>> match.group(0)  # the entire match
'name my_user_name is valid'
>>> match.group(1)  # the first parenthesized subgroup
'my_user_name'

In Python 3.6+ you can also index into a match object instead of using group():

>>> match[0]  # the entire match 
'name my_user_name is valid'
>>> match[1]  # the first parenthesized subgroup
'my_user_name'

Connect to mysql

mysql -uusername -p  -hhostname

show full processlist:

mysql> show full processlist;
+---------+--------+-------------------+---------+---------+------+-------+------------------+
| Id      | User   | Host              | db      | Command | Time | State | Info             |
+---------+--------+-------------------+---------+---------+------+-------+------------------+
| 9255451 | logreg | dmin001.ops:37651 | logdata | Query   |    0 | NULL  | show processlist |
+---------+--------+-------------------+---------+---------+------+-------+------------------+

Kill the specific query. Here id=9255451

mysql> kill 9255451;

If you get permission denied, try this SQL:

CALL mysql.rds_kill(9255451)

This is a state-of-the-union answer as of Windows PowerShell v5.1 / PowerShell Core v6.2.0:

• Andrew Savinykh's ill-fated answer, despite being the accepted one, is, as of this writing, fundamentally flawed (I do hope it gets fixed - there's enough information in the comments - and in the edit history - to do so).

• Ansgar Wiecher's helpful answer works well, but requires direct use of the .NET Framework (and reads the entire file into memory, though that could be changed). Direct use of the .NET Framework is not a problem per se, but is harder to master for novices and hard to remember in general.

• A future version of PowerShell Core will have a
  Convert-TextFile cmdlet with a -LineEnding parameter to allow in-place updating of text files with a specific newline style, as being discussed on GitHub.

In PSv5+, PowerShell-native solutions are now possible, because Set-Content now supports the -NoNewline switch, which prevents undesired appending of a platform-native newline^[1] :

# Convert CRLFs to LFs only.
# Note:
#  * (...) around Get-Content ensures that $file is read *in full*
#    up front, so that it is possible to write back the transformed content
#    to the same file.
#  * + "`n" ensures that the file has a *trailing LF*, which Unix platforms
#     expect.
((Get-Content $file) -join "`n") + "`n" | Set-Content -NoNewline $file

The above relies on Get-Content's ability to read a text file that uses any combination of CR-only, CRLF, and LF-only newlines line by line.

Caveats:

• You need to specify the output encoding to match the input file's in order to recreate it with the same encoding. The command above does NOT specify an output encoding; to do so, use -Encoding; without -Encoding:

  • In Windows PowerShell, you'll get "ANSI" encoding, your system's single-byte, 8-bit legacy encoding, such as Windows-1252 on US-English systems.
  • In PowerShell Core, you'll get UTF-8 encoding without a BOM.

• The input file's content as well as its transformed copy must fit into memory as a whole, which can be problematic with large input files.

• There's a risk of file corruption, if the process of writing back to the input file gets interrupted.

^{[1] In fact, if there are multiple strings to write, -NoNewline also doesn't place a newline between them; in the case at hand, however, this is irrelevant, because only one string is written.}

I realize that an answer was already accepted for this, but from a "strictly *nix purist angle" it seems like the right tool for the job is pcregrep, which doesn't seem to have been mentioned yet. Try changing the lines:

    echo $f | grep -oEi '[0-9]+_([a-z]+)_[0-9a-z]*'
    name=$?

to the following:

    name=$(echo $f | pcregrep -o1 -Ei '[0-9]+_([a-z]+)_[0-9a-z]*')

to get only the contents of the capturing group 1.

The pcregrep tool utilizes all of the same syntax you've already used with grep, but implements the functionality that you need.

The parameter -o works just like the grep version if it is bare, but it also accepts a numeric parameter in pcregrep, which indicates which capturing group you want to show.

With this solution there is a bare minimum of change required in the script. You simply replace one modular utility with another and tweak the parameters.

Interesting Note: You can use multiple -o arguments to return multiple capture groups in the order in which they appear on the line.

A slight change in the execute query will solve the problem:

DECLARE @dbName nvarchar(128) = 'myDb'
DECLARE @siteId int 
exec ('SELECT TOP 1 **''@siteId''** = Id FROM ' + @dbName + '..myTbl')  
select @siteId

You could try something like this:

#!/bin/bash

all_but()
{
    target="$(git rev-parse $1)"
    echo "$target --not"
    git for-each-ref --shell --format="ref=%(refname)" refs/heads | \
    while read entry
    do
        eval "$entry"

        test "$ref" != "$target" && echo "$ref"
    done
}

git log $(all_but $1)

Or, borrowing from the recipe in the Git User's Manual:

#!/bin/bash
git log $1 --not $( git show-ref --heads | cut -d' ' -f2 | grep -v "^$1" )

You can write the where clause as:

where (case when (:stateCode = '') then (1)
            when (:stateCode != '') and (vw.state_cd in (:stateCode)) then 1
            else 0)
       end) = 1;

Alternatively, remove the case entirely:

where (:stateCode = '') or
      ((:stateCode != '') and vw.state_cd in (:stateCode));

Or, even better:

where (:stateCode = '') or vw.state_cd in (:stateCode)

Another (and I think better) way to achieve this is to actually intercept the data. limitTo is okay but what if you're limiting to 10 when your array actually contains thousands?

When calling my service I simply did this:

TaskService.getTasks(function(data){
    $scope.tasks = data.slice(0,10);
});

This limits what is sent to the view, so should be much better for performance than doing this on the front-end.

This process preserve history, but is little workarround:

# make branchs to new files
$: git mv arquivos && git commit

# in original branch, remove original files
$: git rm arquivos && git commit

# do merge and fix conflicts
$: git merge branch-copia-arquivos

# back to original branch and revert commit removing files
$: git revert commit

For setting the name of an existing anonymous function:
(Based on @Marcosc's answer)

var anonymous = function() { return true; }

var name = 'someName';
var strFn = anonymous.toString().replace('function ', 'return function ' + name);
var fn = new Function(strFn)();

console.log(fn()); // —> true

Demo.

Note: Don't do it ;/

As it's not specified if you mean the system's current date or the date held in a variable, I'll answer for latter with an example.

<?php
$dateAsString = "Wed, 11 Apr 2018 19:00:00 -0500";

// This converts it to a unix timestamp so that the date() function can work with it.
$dateAsUnixTimestamp = strtotime($dateAsString);

// Output it month is various formats according to http://php.net/date

echo date('M',$dateAsUnixTimestamp);
// Will output Apr

echo date('n',$dateAsUnixTimestamp);
// Will output 4

echo date('m',$dateAsUnixTimestamp);
// Will output 04
?>

The abort function does this. For example:

abort("Message goes here")

Note: the abort message will be written to STDERR as opposed to puts which will write to STDOUT.

Just posting a some else solution)

function flatMultidimensionalArray(array &$_arr): array
{
    $result = [];
    \array_walk_recursive($_arr, static function (&$value, &$key) use (&$result) {
        $result[$key] = $value;
    });

    return $result;
}

np.max is just an alias for np.amax. This function only works on a single input array and finds the value of maximum element in that entire array (returning a scalar). Alternatively, it takes an axis argument and will find the maximum value along an axis of the input array (returning a new array).

>>> a = np.array([[0, 1, 6],
                  [2, 4, 1]])
>>> np.max(a)
6
>>> np.max(a, axis=0) # max of each column
array([2, 4, 6])

The default behaviour of np.maximum is to take two arrays and compute their element-wise maximum. Here, 'compatible' means that one array can be broadcast to the other. For example:

>>> b = np.array([3, 6, 1])
>>> c = np.array([4, 2, 9])
>>> np.maximum(b, c)
array([4, 6, 9])

But np.maximum is also a universal function which means that it has other features and methods which come in useful when working with multidimensional arrays. For example you can compute the cumulative maximum over an array (or a particular axis of the array):

>>> d = np.array([2, 0, 3, -4, -2, 7, 9])
>>> np.maximum.accumulate(d)
array([2, 2, 3, 3, 3, 7, 9])

This is not possible with np.max.

You can make np.maximum imitate np.max to a certain extent when using np.maximum.reduce:

>>> np.maximum.reduce(d)
9
>>> np.max(d)
9

Basic testing suggests the two approaches are comparable in performance; and they should be, as np.max() actually calls np.maximum.reduce to do the computation.

solution for me:

• apc.ttl=0
• apc.shm_size=anything you want

edit start

warning!

@bokan indicated me that i should add a warning here.

if you have a ttl of 0 this means the every cached item can be purged immediately. so if you have a small cache size like 2mb and a ttl of 0 this would render the apc useless, because the data in the cache gets always overwritten.

lowering the ttl means only that the cache cannot become full, only with items which can't be replaced.

so you have to choose a good balance between ttl and cache size.

in my case i had a cache size of 1gb, so it was more than enough for me.

edit end

had the same issue on centos 5 with php 5.2.17 and noticed that if the cache size is small and the ttl parameter is "high" (like 7200) while having a lot of php files to cache, then the cache fills up quite fast and apc doesn't find anything which it can remove because all files in the cache still fit in the ttl.

increasing the memory size is only a part solution, you still run in this error if you cache fills up and all files are within the ttl.

so my solution was to set the ttl to 0, so apc fills up the cache an there is allways the possibility for apc to clear some memory for new data.

hope that helps

edit: see also: http://pecl.php.net/bugs/bug.php?id=16966

download http://pecl.php.net/get/APC extract and run the apc.php, there you have a nice diagram how your cache usage look like

Seems like the accepted answer does not work anymore. I found the correct method from another post: https://stackoverflow.com/a/46811403/6368026

Now you should use:

http://www.youtube.com/embed/videoseries?list=USERID And the USERID is your youtube user id with 'UU' appended.

For example, if your user id is TlQ5niAIDsLdEHpQKQsupg then you should put UUTlQ5niAIDsLdEHpQKQsupg. If you only have the channel id (which you can find in your channel URL) then just replace the first two characters (UC) with UU.

So in the end you would have an URL like this:

http://www.youtube.com/embed/videoseries?list=UUTlQ5niAIDsLdEHpQKQsupg

When the normType is NORM_MINMAX, cv::normalize normalizes _src in such a way that the min value of dst is alpha and max value of dst is beta. cv::normalize does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).

CV_8UC1 says how many channels dst has.

The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize

It seems like you have it worked out, but for others looking for this answer, an easy way to do this is by printing to stderr. You can do that like this:

from __future__ import print_function # In python 2.7
import sys

@app.route('/button/')
def button_clicked():
    print('Hello world!', file=sys.stderr)
    return redirect('/')

Flask will display things printed to stderr in the console. For other ways of printing to stderr, see this stackoverflow post

And the Postgres equivalent (second line is mandatory only if you want "id" to be a key):

ALTER TABLE tableName ADD id SERIAL;
ALTER TABLE tableName ADD PRIMARY KEY (id);

You must also have the following imports in order to import the DLL

using System.Runtime.InteropServices;
using System.Diagnostics;

Open Terminal and type:

Something I stumbled upon today for a DLL I knew was working fine with my VS2013 project, but not with VS2015:

Go to: Project -> XXXX Properties -> Build -> Uncheck "Prefer 32-bit"

This answer is way overdue and probably won't do any good, but if you. But I hope this will help somebody someday.

You should loop through all tables and test if table.Rows.Count is 0

bool IsEmpty(DataSet dataSet)
{
    foreach(DataTable table in dataSet.Tables)
        if (table.Rows.Count != 0) return false;

    return true;
}

Update: Since a DataTable could contain deleted rows RowState = Deleted, depending on what you want to achive, it could be a good idea to check the DefaultView instead (which does not contain deleted rows).

bool IsEmpty(DataSet dataSet)
{
    return !dataSet.Tables.Cast<DataTable>().Any(x => x.DefaultView.Count > 0);
}

Actions action = new Actions(driver);
action.sendKeys(Keys.RETURN);

The gcf method is depricated in V 0.14, The below code works for me:

plot = dtf.plot()
fig = plot.get_figure()
fig.savefig("output.png")

Using $injector to call service methods in config

I had a similar issue and resolved it by using the $injector service as shown above. I tried injecting the service directly but ended up with a circular dependency on $http. The service displays a modal with the error and I am using ui-bootstrap modal which also has a dependency on $https.

    $httpProvider.interceptors.push(function($injector) {
    return {
        "responseError": function(response) {

            console.log("Error Response status: " + response.status);

            if (response.status === 0) {
                var myService= $injector.get("myService");
                myService.showError("An unexpected error occurred. Please refresh the page.")
            }
        }
    }

The snippet you're showing doesn't seem to be directly responsible for the error.

This is how you can CAUSE the error:

namespace MyNameSpace
{
   int i; <-- THIS NEEDS TO BE INSIDE THE CLASS

   class MyClass
   {
      ...
   }
}

If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }.

There is a syntax problem, because the right syntax to alter command is ALTER TABLE tablename CHANGE OldColumnName NewColunmName DATATYPE;

Set the items into display: inline and use :after:

.text span { display: inline }
.break-after:after { content: '\A'; white-space:pre; }

and add the class into your html spans:

<span class="medium break-after">We</span>

I use this query

SELECT id FROM table_name WHERE field_name REGEXP '"key_name":"([^"])key_word([^"])"';
or
SELECT id FROM table_name WHERE field_name RLIKE '"key_name":"[[:<:]]key_word[[:>:]]"';

The first query I use it to search partial value. The second query I use it to search exact word.

As @milosmns said, you should use imageView.setColorFilter(getResouces().getColor(R.color.blue),android.graphics.PorterDuff.Mode.MULTIPLY);

This API need color value instead of color resource id, That's the root cause why your statement didn't work.

I know it is a tangential answer to the question, but if the intention of the question is 'how do I validate a date?', then why not try letting the programming language do all the hard work (if you are using a language that can)?

e.g. in php

$this_date_object = date_create($this_date);

if ($this_date_object == false )
    {

        // process the error

    }

try this

public static string cleanPhone(string inVal)
        {
            char[] newPhon = new char[inVal.Length];
            int i = 0;
            foreach (char c in inVal)
                if (c.CompareTo('0') > 0 && c.CompareTo('9') < 0)
                    newPhon[i++] = c;
            return newPhon.ToString();
        }

I know, that question has been asked a long long time ago...

I was looking for a short and elegant solution, but couldn't find satisfaction for two reasons:

First, most of the existing solutions replace a list of characters by a list of other characters. Unfortunately, it require to use a specific encoding for the php script file itself which might be unwanted.

Second, using iconv seems to be a good way, but it's not enough as the result of a converted character could be one or two characters, or a Fatal Exception.

So I wrote that small function which does the job :

function replaceAccent($string, $replacement = '_')
{
    $alnumPattern = '/^[a-zA-Z0-9 ]+$/';

    if (preg_match($alnumPattern, $string)) {
        return $string;
    }

    $ret = array_map(
        function ($chr) use ($alnumPattern, $replacement) {
            if (preg_match($alnumPattern, $chr)) {
                return $chr;
            } else {
                $chr = @iconv('ISO-8859-1', 'ASCII//TRANSLIT', $chr);
                if (strlen($chr) == 1) {
                    return $chr;
                } elseif (strlen($chr) > 1) {
                    $ret = '';
                    foreach (str_split($chr) as $char2) {
                        if (preg_match($alnumPattern, $char2)) {
                            $ret .= $char2;
                        }
                    }
                    return $ret;
                } else {
                    // replace whatever iconv fail to convert by something else
                    return $replacement;
                }
            }
        },
        str_split($string)
    );

    return implode($ret);
}

We can read properties file in spring boot using 3 way

1. Read value from application.properties Using @Value

map key as

public class EmailService {

 @Value("${email.username}")
 private String username;

}

2. Read value from application.properties Using @ConfigurationProperties

In this we will map prefix of key using ConfigurationProperties and key name is same as field of class

  @Component
   @ConfigurationProperties("email")
    public class EmailConfig {

        private String   username;
    }

3. Read application.properties Using using Environment object

public class EmailController {

@Autowired
private Environment env;

@GetMapping("/sendmail")
public void sendMail(){     
    System.out.println("reading value from application properties file  using Environment ");
    System.out.println("username ="+ env.getProperty("email.username"));
    System.out.println("pwd ="+ env.getProperty("email.pwd"));
}

Reference : how to read value from application.properties in spring boot

Use the length() method in the File class. From the javadocs:

Returns the length of the file denoted by this abstract pathname. The return value is unspecified if this pathname denotes a directory.

UPDATED Nowadays we should use the Files.size() method:

Paths path = Paths.get("/path/to/file");
long size = Files.size(path);

For the second part of the question, straight from File's javadocs:

• getUsableSpace() Returns the number of bytes available to this virtual machine on the partition named by this abstract pathname

• getTotalSpace() Returns the size of the partition named by this abstract pathname

• getFreeSpace() Returns the number of unallocated bytes in the partition named by this abstract path name

You could do this with an INSTEAD OF INSERT trigger on the table, that checks for the existance of the row and then updates/inserts depending on whether it exists already. There is an example of how to do this for SQL Server 2000+ on MSDN here:

CREATE TRIGGER IO_Trig_INS_Employee ON Employee
INSTEAD OF INSERT
AS
BEGIN
SET NOCOUNT ON
-- Check for duplicate Person. If no duplicate, do an insert.
IF (NOT EXISTS (SELECT P.SSN
      FROM Person P, inserted I
      WHERE P.SSN = I.SSN))
   INSERT INTO Person
      SELECT SSN,Name,Address,Birthdate
      FROM inserted
ELSE
-- Log attempt to insert duplicate Person row in PersonDuplicates table.
   INSERT INTO PersonDuplicates
      SELECT SSN,Name,Address,Birthdate,SUSER_SNAME(),GETDATE()
      FROM inserted
-- Check for duplicate Employee. If no duplicate, do an insert.
IF (NOT EXISTS (SELECT E.SSN
      FROM EmployeeTable E, inserted
      WHERE E.SSN = inserted.SSN))
   INSERT INTO EmployeeTable
      SELECT EmployeeID,SSN, Department, Salary
      FROM inserted
ELSE
--If duplicate, change to UPDATE so that there will not
--be a duplicate key violation error.
   UPDATE EmployeeTable
      SET EmployeeID = I.EmployeeID,
          Department = I.Department,
          Salary = I.Salary
   FROM EmployeeTable E, inserted I
   WHERE E.SSN = I.SSN
END

Assuming you do as David Zaslavsky suggests, so that the first argument simply is the program to run (no option-parsing required), you're dealing with the question of how to pass arguments 2 and on to your external program. Here's a convenient way:

#!/bin/bash
ext_program="$1"
shift
"$ext_program" "$@"

The shift will remove the first argument, renaming the rest ($2 becomes $1, and so on).$@` refers to the arguments, as an array of words (it must be quoted!).

If you must have your --file syntax (for example, if there's a default program to run, so the user doesn't necessarily have to supply one), just replace ext_program="$1" with whatever parsing of $1 you need to do, perhaps using getopt or getopts.

If you want to roll your own, for just the one specific case, you could do something like this:

if [ "$#" -gt 0 -a "${1:0:6}" == "--file" ]; then
    ext_program="${1:7}"
else
    ext_program="default program"
fi

Here is a cheap linq trick.

            SecureString sec = new SecureString();
            string pwd = "abc123"; /* Not Secure! */
            pwd.ToCharArray().ToList().ForEach(sec.AppendChar);
            /* and now : seal the deal */
            sec.MakeReadOnly();

I would recommend checking the connections to show the maximum thread connection is

show variables like "max_connections";

sample

+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 13  |
+-----------------+-------+
1 row in set

Then increase it by example

set global max_connections = 500;

This is an old post, but if anyone comes up with this problem, i post what solved my problem:

I was trying to add the Action Bar Sherlock to my proyect when i get the error:

Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Holo.ActionBar'.

I turns out that the action bar sherlock proyect and my proyect had differents minSdkVersion and targetSdkVersion. Changing that parameters to match in both proyect solved my problem.

<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="17"/>

but layer 02, will cover all drawings in layer 01. I used this to show drawing in both layers. use (background-color: transparent;) in style.

    <div style="position: relative;"> _x000D_
      <canvas id="lay01" width="500" height="500" style="position: absolute; left: 0; top: 0; z-index: 0; background-color: transparent;">_x000D_
      </canvas> _x000D_
      <canvas id="lay02" width="500" height="500" style="position: absolute; left: 0; top: 0; z-index: 1; background-color: transparent;">_x000D_
      </canvas>_x000D_
</div>

Try following command sequence on Ubuntu terminal:

sudo apt-get install software-properties-common
sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install python-pip

If you just want to change file permissions, you want to be careful about using -R on chmod since it will change anything, files or folders. If you are doing a relative change (like adding write permission for everyone), you can do this:

sudo chmod -R a+w /var/www

But if you want to use the literal permissions of read/write, you may want to select files versus folders:

sudo find /var/www -type f -exec chmod 666 {} \;

(Which, by the way, for security reasons, I wouldn't recommend either of these.)

Or for folders:

sudo find /var/www -type d -exec chmod 755 {} \;

Obviously, you'll need a rooted android device. Then set up an FTP server and transfer the files.

The underlying XMLHttpRequest object (used by jQuery to make the request) supports the asynchronous property. Set it to false. Like

async: false

Use Manatee.Json https://github.com/gregsdennis/Manatee.Json/wiki/Usage

And you can convert the entire object to a string, filename.json is expected to be located in documents folder.

        var text = File.ReadAllText("filename.json");
        var json = JsonValue.Parse(text);

        while (JsonValue.Null != null)
        {
            Console.WriteLine(json.ToString());

        }
        Console.ReadLine();

This warning is displayed because a new extension has appeared. It suppouse that you still can use the old one but in some cases it´s impossible.

I show you how I do the connection with database. You need just change the values of the variables.

My connection file: connection.php

<?php    
 $host='IP or Server Name (usually "localhost") ';
 $user='Database user';
 $password='Database password';
 $db='Database name';

 //PHP 5.4 o earlier (DEPRECATED)
 $con = mysql_connect($host,$user,$password) or exit("Connection Error");
 $connection = mysql_select_db($db, $con);

 //PHP 5.5 (New method)
 $connection =  mysqli_connect($host,$user,$password,$db);
?>

The extension changes too when performing a query.

Query File: "example.php"

<?php
 //First I call for the connection
 require("connection.php");

 // ... Here code if you need do something ...

 $query = "Here the query you are going to perform";

 //QUERY PHP 5.4 o earlier (DEPRECATED)
 $result = mysql_query ($query) or exit("The query could not be performed");

 //QUERY PHP 5.5 (NEW EXTENSION)
 $result = mysqli_query ($query) or exit("The query could not be performed");    
?>

This way is using MySQL Improved Extension, but you can use PDO (PHP Data Objects).

First method can be used only with MySQL databases, but PDO can manage different types of databases.

I'm going to put an example but it´s necessary to say that I only use the first one, so please correct me if there is any error.

My PDO connection file: "PDOconnection.php"

<?php
 $hostDb='mysql:host= "Here IP or Server Name";dbname="Database name" ';
 $user='Database user';
 $password='Database password';

 $connection = new PDO($hostDb, $user, $password);
?>

Query File (PDO): "example.php"

<?php
 $query = "Here the query you are going to perform";
 $result=$connection->$query;
?>

To finish just say that of course you can hide the warning but it´s not a good idea because can help you in future save time if an error happens (all of us knows the theory but if you work a lot of hours sometimes... brain is not there ^^ ).

The simplest way today would be to simply request the Material Icons font from Google Fonts, for example in your HTML header tag:

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

or in your stylesheet:

@import url(https://fonts.googleapis.com/icon?family=Material+Icons);

and then use as font icon with ligatures as explained in the md-icon directive. For example:

<md-icon aria-label="Menu" class="material-icons">menu</md-icon>

The complete list of icons/ligatures is at https://www.google.com/design/icons/
