Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

Carriage return is "\r". Mind the double quotes!

I think you want "\r\n" btw to put a line break in your text so it will be rendered correctly in different operating systems.

• Mac: \r
• Linux/Unix: \n
• Windows: \r\n

You don't need --header "Content-Length: $LENGTH".

curl --request POST --data-binary "@template_entry.xml" $URL

Note that GET request does not support content body widely.

Also remember that POST request have 2 different coding schema. This is first form:

  $ nc -l -p 6666 &
  $ curl  --request POST --data-binary "@README" http://localhost:6666

POST / HTTP/1.1
User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6

You probably request this:

-F/--form name=content
           (HTTP) This lets curl emulate a filled-in form in
              which a user has pressed the submit button. This
              causes curl to POST data using the Content- Type
              multipart/form-data according to RFC2388. This
              enables uploading of binary files etc. To force the
              'content' part to be a file, prefix the file name
              with an @ sign. To just get the content part from a
              file, prefix the file name with the symbol <. The
              difference between @ and < is then that @ makes a
              file get attached in the post as a file upload,
              while the < makes a text field and just get the
              contents for that text field from a file.

Using dplyr you can:

df <- df %>% dplyr:: select(grep("ABC", names(df)), grep("XYZ", names(df)))

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

Yes it is definitely possible, but you will have to do

List<MyEnum> al = new ArrayList<MyEnum>();

You can then add elements to al: al.add(ONE) or al.add(TWO).

Place hidden UILabel underneath your textview. Label lines = 0. Set constraints of UITextView to be equal to the UILabel (centerX, centerY, width, height). Works even if you leave scroll behaviour of textView.

Use this

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

From the Tools menu, click on Options, select Designers from the side menu and untick prevent changes that can lead to recreation of a table. Then save the changes

Created the Data frame:

import pandas as pd
dk=pd.DataFrame({"BrandName":['A','B','ABC','D','AB'],"Specialty":['H','I','J','K','L']})

Now use DataFrame.replace() function:

dk.BrandName.replace(to_replace=['ABC','AB'],value='A')

A dirty and easy solution could look like

$scope.showdetails = function(fish_id) {
    angular.forEach($scope.fish, function(fish, key) {
        fish.more = fish.id == fish_id;
    });
};

The difference between different date/time formats in ActiveRecord has little to do with Rails and everything to do with whatever database you're using.

Using MySQL as an example (if for no other reason because it's most popular), you have DATE, DATETIME, TIME and TIMESTAMP column data types; just as you have CHAR, VARCHAR, FLOAT and INTEGER.

So, you ask, what's the difference? Well, some of them are self-explanatory. DATE only stores a date, TIME only stores a time of day, while DATETIME stores both.

The difference between DATETIME and TIMESTAMP is a bit more subtle: DATETIME is formatted as YYYY-MM-DD HH:MM:SS. Valid ranges go from the year 1000 to the year 9999 (and everything in between. While TIMESTAMP looks similar when you fetch it from the database, it's really a just a front for a unix timestamp. Its valid range goes from 1970 to 2038. The difference here, aside from the various built-in functions within the database engine, is storage space. Because DATETIME stores every digit in the year, month day, hour, minute and second, it uses up a total of 8 bytes. As TIMESTAMP only stores the number of seconds since 1970-01-01, it uses 4 bytes.

You can read more about the differences between time formats in MySQL here.

In the end, it comes down to what you need your date/time column to do. Do you need to store dates and times before 1970 or after 2038? Use DATETIME. Do you need to worry about database size and you're within that timerange? Use TIMESTAMP. Do you only need to store a date? Use DATE. Do you only need to store a time? Use TIME.

Having said all of this, Rails actually makes some of these decisions for you. Both :timestamp and :datetime will default to DATETIME, while :date and :time corresponds to DATE and TIME, respectively.

This means that within Rails, you only have to decide whether you need to store date, time or both.

check the following link https://www.geeksforgeeks.org/how-to-create-an-unordered_map-of-user-defined-class-in-cpp/ for more details.

• the custom class must implement the == operator
• must create a hash function for the class (for primitive types like int and also types like string the hash function is predefined)

I've been using Typescript in my current angular project for about a year and a half and while there are a few issues with definitions every now and then the DefinitelyTyped project does an amazing job at keeping up with the latest versions of most popular libraries.

Having said that there is a definite learning curve when transitioning from vanilla JavaScript to TS and you should take into account the ability of you and your team to make that transition. Also if you are going to be using angular 1.x most of the examples you will find online will require you to translate them from JS to TS and overall there are not a lot of resources on using TS and angular 1.x together right now.

If you plan on using angular 2 there are a lot of examples using TS and I think the team will continue to provide most of the documentation in TS, but you certainly don't have to use TS to use angular 2.

ES6 does have some nice features and I personally plan on getting more familiar with it but I would not consider it a production-ready language at this point. Mainly due to a lack of support by current browsers. Of course, you can write your code in ES6 and use a transpiler to get it to ES5, which seems to be the popular thing to do right now.

Overall I think the answer would come down to what you and your team are comfortable learning. I personally think both TS and ES6 will have good support and long futures, I prefer TS though because you tend to get language features quicker and right now the tooling support (in my opinion) is a little better.

Starting with MySQL 5.7, the performance schema exposes all metadata locks, including locks related to the GET_LOCK() function.

See http://dev.mysql.com/doc/refman/5.7/en/metadata-locks-table.html

nvarchar with preprocessing to standardize them as much as possible. You'll probably want to extract extensions and store them in another field.

I've come up with this:

String url = "http://www.example.com/some/path/to/a/file.xml";
String file = url.substring(url.lastIndexOf('/')+1, url.lastIndexOf('.'));

Just add the following rules to the parent element:

display: flex;
justify-content: center; /* align horizontal */
align-items: center; /* align vertical */

Here's a sample demo (Resize window to see the image align)

Browser support for Flexbox nowadays is quite good.

For cross-browser compatibility for display: flex and align-items, you can add the older flexbox syntax as well:

display: -webkit-box;
display: -webkit-flex;
display: -moz-box;
display: -ms-flexbox;
display: flex;
-webkit-flex-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;

Wikipedia has a good article on this, and the official spec is here. From Wikipdia:

The local-part of the e-mail address may use any of these ASCII characters:

• Uppercase and lowercase English letters (a-z, A-Z)
• Digits 0 to 9
• Characters ! # $ % & ' * + - / = ? ^ _ ` { | } ~
• Character . (dot, period, full stop) provided that it is not the first or last character, and provided also that it does not appear two or more times consecutively.

Additionally, quoted-strings (ie: "John Doe"@example.com) are permitted, thus allowing characters that would otherwise be prohibited, however they do not appear in common practice. RFC 5321 also warns that "a host that expects to receive mail SHOULD avoid defining mailboxes where the Local-part requires (or uses) the Quoted-string form".

Wouldn't it be significantly more readable to do a positive match and reject those strings - rather than match the negative to find strings to accept?

/^my/

For individual variables you want to make available on a one off basis you can make it part of the command.

sudo http_proxy=$http_proxy wget "http://stackoverflow.com"

This is usually caused by incorrectly setting up permissions related to running Wireshark correctly. While you can avoid this issue by running Wireshark with elevated privileges (e.g. with sudo), it should generally be avoided (see here, specifically here). This sometimes results from an incomplete or partially successful installation of Wireshark. Since you are running Ubuntu, this can be resolved by following the instructions given in this answer on the Wireshark Q&A site. In summary, after installing Wireshark, execute the following commands:

sudo dpkg-reconfigure wireshark-common 
sudo usermod -a -G wireshark $USER

Then log out and log back in (or reboot), and Wireshark should work correctly without needing additional privileges. Finally, if the problem is still not resolved, it may be that dumpcap was not correctly configured, or there is something else preventing it from operating correctly. In this case, you can set the setuid bit for dumpcap so that it always runs as root.

sudo chmod 4711 `which dumpcap`

One some distros you might get the following error when you execute the command above:

chmod: missing operand after ‘4711’

Try 'chmod --help' for more information.

In this case try running

sudo chmod 4711 `sudo which dumpcap`

I ran into this a while ago and it drove me crazy because it turned out to be simple. So within my View I was using a grid control that obtained data for the grid via an http request. Once the middle tier completed my request and returned the dataset, I received the same error. Turns out my return statement was 'return View(dataset);' instead of 'return Json(dataset);

I had the same problem. In my case I had 2 nested Relative Layouts. RelativeLayout always has to do two measure passes. If you nest RelativeLayouts, you get an exponential measurement algorithm.

One way:

var1="1:2:3:4:5"
var2=${var1##*:}

Another, using an array:

var1="1:2:3:4:5"
saveIFS=$IFS
IFS=":"
var2=($var1)
IFS=$saveIFS
var2=${var2[@]: -1}

Yet another with an array:

var1="1:2:3:4:5"
saveIFS=$IFS
IFS=":"
var2=($var1)
IFS=$saveIFS
count=${#var2[@]}
var2=${var2[$count-1]}

Using Bash (version >= 3.2) regular expressions:

var1="1:2:3:4:5"
[[ $var1 =~ :([^:]*)$ ]]
var2=${BASH_REMATCH[1]}

A generic,simpler and a bit primitive approach to find tag, attribute and value

    Pattern pattern = Pattern.compile("<(\\w+)( +.+)*>((.*))</\\1>");
    System.out.println(pattern.matcher("<asd> TEST</asd>").find());
    System.out.println(pattern.matcher("<asd TEST</asd>").find());
    System.out.println(pattern.matcher("<asd attr='3'> TEST</asd>").find());
    System.out.println(pattern.matcher("<asd> <x>TEST<x>asd>").find());
    System.out.println("-------");
    Matcher matcher = pattern.matcher("<as x> TEST</as>");
    if (matcher.find()) {
        for (int i = 0; i <= matcher.groupCount(); i++) {
            System.out.println(i + ":" + matcher.group(i));
        }
    }

Following up on @Bruno Bronosky and @mrteatime, I offer the suggestion that you just write your boolean return "backwards". This is what I mean:

foo()
{
    if [ "$1" == "bar" ]; then
        true; return
    else
        false; return
    fi;
}

That eliminates the ugly two line requirement for every return statement.

Detailed Example of Normalization Methods

• Pandas normalization (unbiased)
• Sklearn normalization (biased)
• Does biased-vs-unbiased affect Machine Learning?
• Mix-max scaling

References: Wikipedia: Unbiased Estimation of Standard Deviation

Example Data

import pandas as pd
df = pd.DataFrame({
               'A':[1,2,3],
               'B':[100,300,500],
               'C':list('abc')
             })
print(df)
   A    B  C
0  1  100  a
1  2  300  b
2  3  500  c

Normalization using pandas (Gives unbiased estimates)

When normalizing we simply subtract the mean and divide by standard deviation.

df.iloc[:,0:-1] = df.iloc[:,0:-1].apply(lambda x: (x-x.mean())/ x.std(), axis=0)
print(df)
     A    B  C
0 -1.0 -1.0  a
1  0.0  0.0  b
2  1.0  1.0  c

Normalization using sklearn (Gives biased estimates, different from pandas)

If you do the same thing with sklearn you will get DIFFERENT output!

import pandas as pd

from sklearn.preprocessing import StandardScaler
scaler = StandardScaler()


df = pd.DataFrame({
               'A':[1,2,3],
               'B':[100,300,500],
               'C':list('abc')
             })
df.iloc[:,0:-1] = scaler.fit_transform(df.iloc[:,0:-1].to_numpy())
print(df)
          A         B  C
0 -1.224745 -1.224745  a
1  0.000000  0.000000  b
2  1.224745  1.224745  c

Does Biased estimates of sklearn makes Machine Learning Less Powerful?

NO.

The official documentation of sklearn.preprocessing.scale states that using biased estimator is UNLIKELY to affect the performance of machine learning algorithms and we can safely use them.

From official documentation:

We use a biased estimator for the standard deviation, equivalent to numpy.std(x, ddof=0). Note that the choice of ddof is unlikely to affect model performance.

What about MinMax Scaling?

There is no Standard Deviation calculation in MinMax scaling. So the result is same in both pandas and scikit-learn.

import pandas as pd
df = pd.DataFrame({
               'A':[1,2,3],
               'B':[100,300,500],
             })
(df - df.min()) / (df.max() - df.min())
     A    B
0  0.0  0.0
1  0.5  0.5
2  1.0  1.0


# Using sklearn
from sklearn.preprocessing import MinMaxScaler

scaler = MinMaxScaler() 
arr_scaled = scaler.fit_transform(df) 

print(arr_scaled)
[[0.  0. ]
 [0.5 0.5]
 [1.  1. ]]

df_scaled = pd.DataFrame(arr_scaled, columns=df.columns,index=df.index)
print(df_scaled)
     A    B
0  0.0  0.0
1  0.5  0.5
2  1.0  1.0

Since Unity 4.3 you also have to enable External option from preferences, so full setup process looks like:

1. Enable External option in Unity ? Preferences ? Packages ? Repository
2. Switch to Hidden Meta Files in Editor ? Project Settings ? Editor ? Version Control Mode
3. Switch to Force Text in Editor ? Project Settings ? Editor ? Asset Serialization Mode
4. Save scene and project from File menu

Note that the only folders you need to keep under source control are Assets and ProjectSettigns.

More information about keeping Unity Project under source control you can find in this post.

Imagine if one went into a store and asked for a device with a power switch. You didn't say whether you wanted a copier, television, vacuum cleaner, desk lamp, waffle maker, or anything. You asked for a device with a power switch. Would you expect the clerk to offer you something that could only be described as "a device with a power switch"?

A typical interface would be analogous to the description "a device with a power switch". Knowing that a piece of equipment is " a device with a power switch" would allow one to do some operations with it (i.e. turn it on and off), and one might plausibly want a list of e.g. "devices with power switches that will need to be turned off at the end of the day", without the devices having to share any characteristic beyond having a power switch, but such situations generally only apply when applying some common operation to devices that were created for some more specific purpose. When creating something from scratch, one would more likely wand a "copier", "television", "vacuum cleaner", or other particular type of device, than some random "device with a power switch".

There are some circumstances where one may want a vaguely-defined object, and really not care about what exactly it is. "Give me your cheapest device that can boil water". It would be nice if one could specify that when someone asks for an arbitrary object with "water boiling" ability, they should be offered an Acme 359 Electric Teakettle, and indeed when using classes it's possible to do that. Note, however, that someone who asks for a "device to boil water" would not be given a "device to boil water", but an "Acme 359 Electric Teakettle".

So I figured out what is wrong with this statement:

Import-Csv H:\Programs\scripts\SomeText.csv |`

(Original)

Import-Csv H:\Programs\scripts\SomeText.csv -Delimiter "|"

(Proposed, You must use quotations; otherwise, it will not work and ISE will give you an error)

It requires the -Delimiter "|", in order for the variable to be populated with an array of items. Otherwise, Powershell ISE does not display the list of items.

I cannot say that I would recommend the | operator, since it is used to pipe cmdlets into one another.

I still cannot get the if statement to return true and output the values entered via the prompt.

If anyone else can help, it would be great. I still appreciate the post, it has been very helpful!

Here's a combination of some of these answers. This can be used for input fields. Deals with phone numbers that are 7 and 10 digits long.

// Used to format phone number
function phoneFormatter() {
  $('.phone').on('input', function() {
    var number = $(this).val().replace(/[^\d]/g, '')
    if (number.length == 7) {
      number = number.replace(/(\d{3})(\d{4})/, "$1-$2");
    } else if (number.length == 10) {
      number = number.replace(/(\d{3})(\d{3})(\d{4})/, "($1) $2-$3");
    }
    $(this).val(number)
  });
}

Please use this on SQL Server 2005:

sp_rename old_table_name , new_table_name

it will give you:

Caution: Changing any part of an object name could break scripts and stored procedures.

but your table name will be changed.

Original answer:

I too tried to change the support library to "23". When I changed the targetSdkVersion to 23, Android Studio reported the following error:

This support library should not use a lower version (22) than the targetSdkVersion (23)

I simply changed:

compile 'com.android.support:appcompat-v7:23.0.0'

to

compile 'com.android.support:appcompat-v7:+'

Although this fixed my issue, you should not use dynamic versions. After a few hours the new support repository was available and it is currently 23.0.1.

Pro tip:

You can use double quotes and create a ${supportLibVersion} variable for simplicity. Example:

ext {
    supportLibVersion = '23.1.1'
}

compile "com.android.support:appcompat-v7:${supportLibVersion}"
compile "com.android.support:design:${supportLibVersion}"
compile "com.android.support:palette-v7:${supportLibVersion}"
compile "com.android.support:customtabs:${supportLibVersion}"
compile "com.android.support:gridlayout-v7:${supportLibVersion}"

@rap-2-h and @Ztuons Ch's answer doesn't allow for the showTooltips option to be active, but what you can do is create and layer a second canvas object behind the one rendering the chart.

The important part is the styling required in the divs and for the canvas object itself so that they render on top of each other.

Update

Module not specified

According to the snapshot you have provided this problem is because you have not determined the app module of your project, so I suggest you to choose the app module from configuration. For example:

There may be many ways.. But I implemented by following two ways

Given example is of maven project.

1. Using Dockerfile in maven project

Use the following file structure:

Demo
+-- src
|    +-- main
|    ¦   +-- java
|    ¦       +-- org
|    ¦           +-- demo
|    ¦               +-- Application.java
|    ¦   
|    +-- test
|
+---- Dockerfile
+---- pom.xml

And update the Dockerfile as:

FROM java:8
EXPOSE 8080
ADD /target/demo.jar demo.jar
ENTRYPOINT ["java","-jar","demo.jar"]

Navigate to the project folder and type following command you will be ab le to create image and run that image:

$ mvn clean
$ mvn install
$ docker build -f Dockerfile -t springdemo .
$ docker run -p 8080:8080 -t springdemo

Get video at Spring Boot with Docker

2. Using Maven plugins

Add given maven plugin in pom.xml

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <version>0.4.5</version>
        <configuration>
            <imageName>springdocker</imageName>
            <baseImage>java</baseImage>
            <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>
            <resources>
                <resource>
                    <targetPath>/</targetPath>
                    <directory>${project.build.directory}</directory>
                    <include>${project.build.finalName}.jar</include>
                </resource>
            </resources>
        </configuration>
    </plugin>

Navigate to the project folder and type following command you will be able to create image and run that image:

$ mvn clean package docker:build
$ docker images
$ docker run -p 8080:8080 -t <image name>

In first example we are creating Dockerfile and providing base image and adding jar an so, after doing that we will run docker command to build an image with specific name and then run that image..

Whereas in second example we are using maven plugin in which we providing baseImage and imageName so we don't need to create Dockerfile here.. after packaging maven project we will get the docker image and we just need to run that image..

Press Windows + R type cmd and Enter

In command prompt type

telnet "machine name/ip" "port number"

If port is not open, this message will display:

"Connecting To "machine name"...Could not open connection to the host, on port "port number":

Otherwise you will be take in to opened port (empty screen will display)

I ran across this article in the results returned by a search related to the IF command in a batch file, and I couldn't resist the opportunity to correct the misconception that IF blocks are limited to single commands. Following is a portion of a production Windows NT command script that runs daily on the machine on which I am composing this reply.

    if "%COPYTOOL%" equ "R" (
    WWLOGGER.exe "%APPDATA%\WizardWrx\%~n0.LOG" "Using RoboCopy to make a backup of %USERPROFILE%\My Documents\Outlook Files\*"
    %TOOLPATH% %SRCEPATH% %DESTPATH% /copyall %RCLOGSTR% /m /np /r:0 /tee
    C:\BIN\ExitCodeMapper.exe C:\BIN\ExitCodeMapper.INI[Robocopy] %TEMP%\%~n0.TMP %ERRORLEVEL%
) else (
    WWLOGGER.exe "%APPDATA%\WizardWrx\%~n0.LOG" "Using XCopy to make a backup of %USERPROFILE%\My Documents\Outlook Files\*"
    call %TOOLPATH%  "%USERPROFILE%\My Documents\Outlook Files\*" "%USERPROFILE%\My Documents\Outlook Files\_backups" /f /m /v /y
    C:\BIN\ExitCodeMapper.exe C:\BIN\ExitCodeMapper.INI[Xcopy] %TEMP%\%~n0.TMP %ERRORLEVEL%
)

Perhaps blocks of two or more lines applies exclusively to Windows NT command scripts (.CMD files), because a search of the production scripts directory of an application that is restricted to old school batch (.BAT) files, revealed only one-command blocks. Since the application has gone into extended maintenance (meaning that I am not actively involved in supporting it), I can't say whether that is because I didn't need more than one line, or that I couldn't make them work.

Regardless, if the latter is true, there is a simple workaround; move the multiple lines into either a separate batch file or a batch file subroutine. I know that the latter works in both kinds of scripts.

add this to your my.cnf

innodb_buffer_pool_size=1G

restart your mysql to make it effect

To quote the Christmas analogy again:

In SQL, NULL basically means "closed box" (unknown). So, the result of comparing two closed boxes will also be unknown (null).

I understand, for a developer, this is counter-intuitive, because in programming languages, often NULL rather means "empty box" (known). And comparing two empty boxes will naturally yield true / equal.

This is why JavaScript for example distinguishes between null and undefined.

You can change your model method to property and use it in serializer with this approach.

class Foo(models.Model):
    . . .
    @property
    def my_field(self):
        return stuff
    . . .

class FooSerializer(ModelSerializer):
    my_field = serializers.ReadOnlyField(source='my_field')

    class Meta:
        model = Foo
        fields = ('my_field',)

Edit: With recent versions of rest framework (I tried 3.3.3), you don't need to change to property. Model method will just work fine.

Best general purpose - Especially short arrays (1000 items or less) and coders that are unsure of what optimizations best suit their needs.

# $value can be any regex. be safe
if ( grep( /^$value$/, @array ) ) {
  print "found it";
}

It has been mentioned that grep passes through all values even if the first value in the array matches. This is true, however grep is still extremely fast for most cases. If you're talking about short arrays (less than 1000 items) then most algorithms are going to be pretty fast anyway. If you're talking about very long arrays (1,000,000 items) grep is acceptably quick regardless of whether the item is the first or the middle or last in the array.

Optimization Cases for longer arrays:

If your array is sorted, use a "binary search".

If the same array is repeatedly searched many times, copy it into a hash first and then check the hash. If memory is a concern, then move each item from the array into the hash. More memory efficient but destroys the original array.

If same values are searched repeatedly within the array, lazily build a cache. (as each item is searched, first check if the search result was stored in a persisted hash. if the search result is not found in the hash, then search the array and put the result in the persisted hash so that next time we'll find it in the hash and skip the search).

Note: these optimizations will only be faster when dealing with long arrays. Don't over optimize.

The tomcat version is implied by the jboss server version.

EDIT:

A complete list of versions you find here VersionOfTomcatInJBossAS

Where you reach your JBoss depends on the interface it is bound, using -b hostname If you start using JBoss with -b 0.0.0.0 option. That way, you can access the system using localhost, machineName and even the IP address. By default it's localhost, if you use th -b option you need to replace localhost by yourhostname.

Bitmasks are used when you want to encode multiple layers of information in a single number.

So (assuming unix file permissions) if you want to store 3 levels of access restriction (read, write, execute) you could check for each level by checking the corresponding bit.

rwx
---
110

110 in base 2 translates to 6 in base 10.

So you can easily check if someone is allowed to e.g. read the file by and'ing the permission field with the wanted permission.

Pseudocode:

PERM_READ = 4
PERM_WRITE = 2
PERM_EXEC = 1

user_permissions = 6

if (user_permissions & PERM_READ == TRUE) then
  // this will be reached, as 6 & 4 is true
fi

You need a working understanding of binary representation of numbers and logical operators to understand bit fields.

Use Console.Write instead, so there's no newline written:

Console.Write("What is your name? ");
var name = Console.ReadLine();

To post your html, javascript,c# and java you should convert special characters to HTML code. as '<' as < and '>' to > and e.t.c..

Add this link Code Converter to iGoogle. This will help you to convert the special characters.

Then add SyntaxHighlighter 3.0.83 new version to customize your code in blogger. But you should know How to configure the syntaxHighlighter in your blogger template.

you can try this

this will keep the table head fixed ,and scroll only the table content .

To do so without compiling the Regex first, use a lambda function - for example:

from re import match

values = ['123', '234', 'foobar']
filtered_values = list(filter(lambda v: match('^\d+$', v), values))

print(filtered_values)

Returns:

['123', '234']

filter() just takes a callable as it's first argument, and returns a list where that callable returned a 'truthy' value.

A Swift3 version:

extension UIView {

    func startRotate() {
        let rotation : CABasicAnimation = CABasicAnimation(keyPath: "transform.rotation.z")
        rotation.fromValue = 0
        rotation.toValue = NSNumber(value: M_PI * 2)
        rotation.duration = 2
        rotation.isCumulative = true
        rotation.repeatCount = FLT_MAX
        self.layer.add(rotation, forKey: "rotationAnimation")
    }

    func stopRotate() {
        self.layer.removeAnimation(forKey: "rotationAnimation")
    }
}

And remember to call startRotate in viewWillAppear not in viewDidLoad.

You want .charAt()

Here's a tutorial

"mystring".charAt(2)

returns s

If you're hellbent on having a string there are a couple of ways to convert a char to a string:

String mychar = Character.toString("mystring".charAt(2));

Or

String mychar = ""+"mystring".charAt(2);

Or even

String mychar = String.valueOf("mystring".charAt(2));

For example.

A nice practical use of this is if you want to make your own HtmlHelper extensions. For example, I hate trying to remember the <link> tag syntax, so I've created my own extension method to make a <link> tag:

<Extension()> _
Public Function CssBlock(ByVal html As HtmlHelper, ByVal src As String, ByVal Optional ByVal htmlAttributes As Object = Nothing) As MvcHtmlString
    Dim tag = New TagBuilder("link")
    tag.MergeAttribute("type", "text/css")
    tag.MergeAttribute("rel", "stylesheet")
    tag.MergeAttribute("href", src)
    tag.MergeAttributes(New RouteValueDictionary(htmlAttributes))
    Dim result = tag.ToString(TagRenderMode.Normal)
    Return MvcHtmlString.Create(result)
End Function

I could have returned String from this method, but if I had the following would break:

<%: Html.CssBlock(Url.Content("~/sytles/mysite.css")) %>

With MvcHtmlString, using either <%: ... %> or <%= ... %> will both work correctly.

Simple socket server app example

I've already posted a client example at: https://stackoverflow.com/a/35971718/895245 , so here goes a server example.

This example app runs a server that returns a ROT-1 cypher of the input.

You would then need to add an Exit button + some sleep delays, but this should get you started.

To play with it:

• install the app
• get your phone and PC on a LAN
• find your phone's IP with https://android.stackexchange.com/a/130468/126934
• run netcat $PHONE_IP 12345
• type some lines

Android sockets are the same as Java's, except we have to deal with some permission issues.

Just go to start and then type tomcat. If it is installed it will give you the directory where it is installed. Then you can select that path and run it from command prompt. Example if tomcat is installed in C:\Programfile\tomcat. You need to set this path in command prompt,go to bin folder and startup. Example: C:\Programfile\tomcat\bin\startup. Else you can also run it by directly going to the path and run startup batch file.

I use this for a couple built-in primitive functions that I felt were really missing. One example is a find function that has the same usage semantics as filter, map, reduce.

def builtin_find(f, x, d=None):
    for i in x:
        if f(i):
            return i
    return d

import __builtin__
__builtin__.find = builtin_find

Once this is run (for instance, by importing near your entry point) all your modules can use find() as though, obviously, it was built in.

find(lambda i: i < 0, [1, 3, 0, -5, -10])  # Yields -5, the first negative.

Note: You can do this, of course, with filter and another line to test for zero length, or with reduce in one sort of weird line, but I always felt it was weird.

Yes, I think for Windows users you need to change all the python3 calls to python to solve your original error. This change will run the Python version set in your current environment. If you need to keep this call as it is (aka python3) because you are working in cross-platform or for any other reason, then a work around is to create a soft link. To create it, go to the folder that contains the Python executable and create the link. For example, this worked in my case in Windows 10 using mklink:

cd C:\Python3
mklink python3.exe python.exe

Use a (soft) symbolic link in Linux:

cd /usr/bin/python3
ln -s python.exe python3.exe

This is work for me 100% :

let data:Observable<any> = this.http.post(url, postData);
  data.subscribe((data) => {

  let d = data.json();
  console.log(d);
  console.log("result = " + d.result);
  console.log("url = " + d.image_url);      
  loader.dismiss();
});

You can get posted form data from request.form and query string data from request.args.

myvar =  request.form["myvar"]

myvar = request.args["myvar"]

First off, (though this won't change the performance at all) consider cleaning up your code, similar to this:

import matplotlib.pyplot as plt
import numpy as np
import time

x = np.arange(0, 2*np.pi, 0.01)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)
styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
lines = [ax.plot(x, y, style)[0] for ax, style in zip(axes, styles)]

fig.show()

tstart = time.time()
for i in xrange(1, 20):
    for j, line in enumerate(lines, start=1):
        line.set_ydata(np.sin(j*x + i/10.0))
    fig.canvas.draw()

print 'FPS:' , 20/(time.time()-tstart)

With the above example, I get around 10fps.

Just a quick note, depending on your exact use case, matplotlib may not be a great choice. It's oriented towards publication-quality figures, not real-time display.

However, there are a lot of things you can do to speed this example up.

There are two main reasons why this is as slow as it is.

1) Calling fig.canvas.draw() redraws everything. It's your bottleneck. In your case, you don't need to re-draw things like the axes boundaries, tick labels, etc.

2) In your case, there are a lot of subplots with a lot of tick labels. These take a long time to draw.

Both these can be fixed by using blitting.

To do blitting efficiently, you'll have to use backend-specific code. In practice, if you're really worried about smooth animations, you're usually embedding matplotlib plots in some sort of gui toolkit, anyway, so this isn't much of an issue.

However, without knowing a bit more about what you're doing, I can't help you there.

Nonetheless, there is a gui-neutral way of doing it that is still reasonably fast.

import matplotlib.pyplot as plt
import numpy as np
import time

x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)

fig.show()

# We need to draw the canvas before we start animating...
fig.canvas.draw()

styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
    return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]

# Let's capture the background of the figure
backgrounds = [fig.canvas.copy_from_bbox(ax.bbox) for ax in axes]

tstart = time.time()
for i in xrange(1, 2000):
    items = enumerate(zip(lines, axes, backgrounds), start=1)
    for j, (line, ax, background) in items:
        fig.canvas.restore_region(background)
        line.set_ydata(np.sin(j*x + i/10.0))
        ax.draw_artist(line)
        fig.canvas.blit(ax.bbox)

print 'FPS:' , 2000/(time.time()-tstart)

This gives me ~200fps.

To make this a bit more convenient, there's an animations module in recent versions of matplotlib.

As an example:

import matplotlib.pyplot as plt
import matplotlib.animation as animation
import numpy as np

x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)

styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
    return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]

def animate(i):
    for j, line in enumerate(lines, start=1):
        line.set_ydata(np.sin(j*x + i/10.0))
    return lines

# We'd normally specify a reasonable "interval" here...
ani = animation.FuncAnimation(fig, animate, xrange(1, 200), 
                              interval=0, blit=True)
plt.show()

What kind of collection? If it's an implementation of the List interface then you could just use it.nextIndex() - 1.

If all else fails, like it did in my case, then just disable annotations. I started a c++11 project with own makefile but couldn't fix all the problems. Even if you disable annotations, eclipse will still be able to help you do some autocompletion. Most importantly, the debugger still works!

Sometimes I wish it were possible to write a function in MSIL inline in C#, similar to how you can write inline assembler in C.

For the record, I once wrote a helper library for C# with various functions for things that were impossible to write in C# but can be written in MSIL (non-zero-based arrays for example). I had this function:

.method public hidebysig static void Swap<T> (
        !!T& a,
        !!T& b
    ) cil managed 
{
    .maxstack 4

    ldarg.1      // push a& reference
    ldarg.2      // push b& reference
    ldobj !!T    // pop b&, push b
    ldarg.2      // push b& reference
    ldarg.1      // push a& reference
    ldobj !!T    // pop a&, push a
    stobj !!T    // store a in b&
    stobj !!T    // store b in a&
    ret
}

And no locals needed. Of course this was just me being silly...

Please try this code

$(this).animate({'width': 'toggle'});

I reference all the methods.

Encode the query twice is the fast solution.

const query = a=123&b=456;
const url = `https://example.com/test?${encodeURIComponent(encodeURIComponent(query),)}`;


const twitterSharingURL=`https://twitter.com/intent/tweet?&url=${url}`

Inputs of type="image" don't send their name/value pair when used to submit the form. To me, that sounds like a bug, but that's how it is.

To get around this, you can replace the input with a button of type="submit", and put a img element inside.

Unfortunately, that causes your image to be in a ugly HTML "button". However, assuming you aren't using the standard HTML button anywhere, you can just override the stylesheet, and then everything should work as expected:

button, input[type="submit"], input[type="reset"] {_x000D_
 background: none;_x000D_
 color: inherit;_x000D_
 border: none;_x000D_
 padding: 0;_x000D_
 font: inherit;_x000D_
 cursor: pointer;_x000D_
 outline: inherit;_x000D_
}

<form action="/post">_x000D_
<input name="test">_x000D_
<button type="submit" name="submit_button" value="submitted">_x000D_
<img src="https://via.placeholder.com/32" alt="image">_x000D_
</button>_x000D_
</form>

Eclipse doesn't pull the tooltips from the javadoc location. It only uses the javadoc location to prepend to the link if you say open in browser, you need to download and attach the source for the JDK in order to get the tooltips. For all the JARs under the JRE you should have the following for the javadoc location: http://java.sun.com/javase/6/docs/api/. For resources.jar, rt.jar, jsse.jar, jce.jar and charsets.jar you should attach the source available here.

Have you tried, after calling DataBind on your DropDownList, to do something like ddl.SelectedIndex = 0 ?

Building on the brilliant logic / code from mathematix and scottyc, I submit:

DECLARE @a INT, @b INT, @c INT = 0

WHILE @c < 100
    BEGIN
        SET @c += 1
        SET @a = ROUND(RAND()*100,0)-50
        SET @b = ROUND(RAND()*100,0)-50
        SELECT @a AS a, @b AS b,
            @a - ( ABS(@a-@b) + (@a-@b) ) / 2 AS MINab,
            @a + ( ABS(@b-@a) + (@b-@a) ) / 2 AS MAXab,
            CASE WHEN (@a <= @b AND @a = @a - ( ABS(@a-@b) + (@a-@b) ) / 2)
            OR (@a >= @b AND @a = @a + ( ABS(@b-@a) + (@b-@a) ) / 2)
            THEN 'Success' ELSE 'Failure' END AS Status
    END

Although the jump from scottyc's MIN function to the MAX function should have been obvious to me, it wasn't, so I've solved for it and included it here: SELECT @a + ( ABS(@b-@a) + (@b-@a) ) / 2. The randomly generated numbers, while not proof, should at least convince skeptics that both formulae are correct.

Routes monitor the $location service and respond to changes in URL (typically through the hash). To "activate" a route, you simply change the URL. The easiest way to do that is with anchor tags.

<a href="#/home">Go Home</a>
<a href="#/about">Go to About</a>

Nothing more complicated is needed. If, however, you must do this from code, the proper way is by using the $location service:

$scope.go = function ( path ) {
  $location.path( path );
};

Which, for example, a button could trigger:

<button ng-click="go('/home')"></button>

An Enumerator shows you the items in a list or collection. Each instance of an Enumerator is at a certain position (the 1st element, the 7th element, etc) and can give you that element (IEnumerator.Current) or move to the next one (IEnumerator.MoveNext). When you write a foreach loop in C#, the compiler generates code that uses an Enumerator.

An Enumerable is a class that can give you Enumerators. It has a method called GetEnumerator which gives you an Enumerator that looks at its items. When you write a foreach loop in C#, the code that it generates calls GetEnumerator to create the Enumerator used by the loop.

Typescript does not yet support Map.

In newer versions of VS Code, you navigate to settings (Ctrl+,), and make sure to select Workspace Settings at the top right.

Then add a files.exclude option to specify patterns to exclude.

You can also add search.exclude if you only want to exclude a file from search results, and not from the folder explorer.

A lot of folks get confused about the difference between char* and char[] in conjunction with string literals in C. When you write:

char *foo = "hello world";

...you are actually pointing foo to a constant block of memory (in fact, what the compiler does with "hello world" in this instance is implementation-dependent.)

Using char[] instead tells the compiler that you want to create an array and fill it with the contents, "hello world". foo is the a pointer to the first index of the char array. They both are char pointers, but only char[] will point to a locally allocated and mutable block of memory.

If I have to change the contents of my options menu I perform it during the onMenuOpened(). This allows me to check the running state at the very moment that the user is accessing the menu.

public boolean onMenuOpened(int featureid, Menu menu)
    {
        menu.clear();
        if (!editable)
        {
            MenuItem itemAdd = menu.add(0, REASSIGN, Menu.NONE, context.getString(R.string.reassign));
            MenuItem itemMod = menu.add(1, EDIT, Menu.NONE, context.getString(R.string.modify));
            MenuItem itemDel = menu.add(2, DELETE, Menu.NONE, context.getString(R.string.delete));
            itemAdd.setShortcut('0', 'a');
            itemMod.setShortcut('1', 'm');
            itemDel.setShortcut('2', 'd');
        }
        else
        {
            MenuItem itemSave = menu.add(3, SAVE, Menu.NONE, context.getString(R.string.savechanges));
            itemSave.setShortcut('0', 'S');
        }


        return true;
    }

For the next visitor coming along: use the recursive array walk; it visits every "leaf" in the multidimensional array. Here's for inspiration:

function getMDArrayValueByKey($a, $k) {
    $r = [];
    array_walk_recursive ($a, 
                          function ($item, $key) use ($k, &$r) {if ($key == $k) $r[] = $item;}
                          );
    return $r;
}

You need to use a global regular expression for this. Try it this way:

str.replace(/"/g, '\\"');

Check out regex syntax and options for the replace function in Using Regular Expressions with JavaScript.

print(flag.utf16.count)
// Prints "4"

// Prints "8"

To develop the answer of @Caumons:

Imagine one father class has many children and there is a need to add a common field into that class. If you consider the mentioned approach, you should go to each children class one by one and refactor their constructors for the new field. therefore that solution is not a promising solution in this scenario

Now take a look at this solution.

A father can receive an self object from each children. Here is a father class:

public class Father {

    protected String fatherField;

    public Father(Father a){
        fatherField = a.fatherField;
    }

    //Second constructor
    public Father(String fatherField){
        this.fatherField = fatherField;
    }

    //.... Other constructors + Getters and Setters for the Fields
}

Here is our child class that should implement one of its father constructor, in this case the aforementioned constructor :

public class Child extends Father {

    protected String childField;

    public Child(Father father, String childField ) {
        super(father);
        this.childField = childField;
    }

    //.... Other constructors + Getters and Setters for the Fields

    @Override
    public String toString() {
        return String.format("Father Field is: %s\nChild Field is: %s", fatherField, childField);
    }
}

Now we test out application:

public class Test {
    public static void main(String[] args) {
        Father fatherObj = new Father("Father String");
        Child child = new Child(fatherObj, "Child String");
        System.out.println(child);
    }
}

And here is the result :

Father Field is: Father String

Child Field is: Child String

Now you can easily add new fields to father class without being worried of your children codes to break;

Try this

if(!a || a.length === 0)

List<T>.Insert(0, item);

It wants the full time in DD-MM-YYYY_HH-MM-SS.TT where TT is the ticks. The exception says it all.

this.router.navigate([<route>]));

For joins, I strongly prefer query-syntax for all the details that are happily hidden (not the least of which are the transparent identifiers involved with the intermediate projections along the way that are apparent in the dot-syntax equivalent). However, you asked regarding Lambdas which I think you have everything you need - you just need to put it all together.

var categorizedProducts = product
    .Join(productcategory, p => p.Id, pc => pc.ProdId, (p, pc) => new { p, pc })
    .Join(category, ppc => ppc.pc.CatId, c => c.Id, (ppc, c) => new { ppc, c })
    .Select(m => new { 
        ProdId = m.ppc.p.Id, // or m.ppc.pc.ProdId
        CatId = m.c.CatId
        // other assignments
    });

If you need to, you can save the join into a local variable and reuse it later, however lacking other details to the contrary, I see no reason to introduce the local variable.

Also, you could throw the Select into the last lambda of the second Join (again, provided there are no other operations that depend on the join results) which would give:

var categorizedProducts = product
    .Join(productcategory, p => p.Id, pc => pc.ProdId, (p, pc) => new { p, pc })
    .Join(category, ppc => ppc.pc.CatId, c => c.Id, (ppc, c) => new {
        ProdId = ppc.p.Id, // or ppc.pc.ProdId
        CatId = c.CatId
        // other assignments
    });

...and making a last attempt to sell you on query syntax, this would look like this:

var categorizedProducts =
    from p in product
    join pc in productcategory on p.Id equals pc.ProdId
    join c in category on pc.CatId equals c.Id
    select new {
        ProdId = p.Id, // or pc.ProdId
        CatId = c.CatId
        // other assignments
    };

Your hands may be tied on whether query-syntax is available. I know some shops have such mandates - often based on the notion that query-syntax is somewhat more limited than dot-syntax. There are other reasons, like "why should I learn a second syntax if I can do everything and more in dot-syntax?" As this last part shows - there are details that query-syntax hides that can make it well worth embracing with the improvement to readability it brings: all those intermediate projections and identifiers you have to cook-up are happily not front-and-center-stage in the query-syntax version - they are background fluff. Off my soap-box now - anyhow, thanks for the question. :)

For some hosting accounts, I'm on Ultimate Classic Linux, the file name you need to use is .user.ini.

Try this http://ionicframework.com/docs/api/service/$ionicScrollDelegate/

It does scroll to the top of the list scrollTop()

Since I just ran in to this problem on a shared host and was unable to add the values to my .htaccess file I thought I'd share my solution.

I made an ini file with the values in it. Simple as that:

Make a file called ".user.ini" and add your values

upload_max_filesize = 150M
post_max_size = 150M

Boom, problem solved.

Note that this information is readily available in the documentation; just press F1. The page you link to deals with Visual Basic .NET, not VBA. While (no pun intended) there is some degree of overlap in syntax between VBA and VB.NET, one can't just assume that the documentation for the one can be applied directly to the other.

Also in the VBA help file:

Tip The Do...Loop statement provides a more structured and flexible way to perform looping.

According to the documentation:

If this abstract pathname does not denote a directory, then this method returns null.

So you should check if listFiles is null and only continue if it's not

boolean deleteDirectory(File path) {
    if(path.exists()) {
        File[] files = path.listFiles();
        if (files == null) {
            return false;
        }
        for (File file : files) {
            if (file.isDirectory()) {
                deleteDirectory(file);
            } else {
                boolean wasSuccessful = file.delete();
                if (wasSuccessful) {
                    Log.i("Deleted ", "successfully");
                }
            }
        }
    }
    return(path.delete());
}

From man 1 pkill

-f     The pattern is normally only matched against the process name.
       When -f is set, the full command line is used.

Which means, for example, if we see these lines in ps aux:

apache   24268  0.0  2.6 388152 27116 ?        S    Jun13   0:10 /usr/sbin/httpd
apache   24272  0.0  2.6 387944 27104 ?        S    Jun13   0:09 /usr/sbin/httpd
apache   24319  0.0  2.6 387884 27316 ?        S    Jun15   0:04 /usr/sbin/httpd

We can kill them all using the pkill -f option:

pkill -f httpd

This worked for me plt.savefig(save_path,bbox_inches='tight', pad_inches=0, transparent=True)

If you just want the date:

SELECT MIN(date) as EarliestDate
FROM YourTable
WHERE id = 2

If you want all of the information:

SELECT TOP 1 id, name, score, date
FROM YourTable
WHERE id = 2
ORDER BY Date

Prevent loops when you can. Loops often lead to cursors, and cursors are almost never necessary and very often really inefficient.

CSS3 has the overflow-x property, but I wouldn't expect great support for that. In CSS2 all you can do is set a general scroll policy and work your widths and heights not to mess them up.

I wrote a simple wrapper around Google's .Net client library, it exposes a simpler database-like interface, with strongly-typed record types. Here's some sample code:

public class Entity {
    public int IntProp { get; set; }
    public string StringProp { get; set; }
}

var e1 = new Entity { IntProp = 2 };
var e2 = new Entity { StringProp = "hello" };
var client = new DatabaseClient("[email protected]", "password");
const string dbName = "IntegrationTests";
Console.WriteLine("Opening or creating database");
db = client.GetDatabase(dbName) ?? client.CreateDatabase(dbName); // databases are spreadsheets
const string tableName = "IntegrationTests";
Console.WriteLine("Opening or creating table");
table = db.GetTable<Entity>(tableName) ?? db.CreateTable<Entity>(tableName); // tables are worksheets
table.DeleteAll();
table.Add(e1);
table.Add(e2);
var r1 = table.Get(1);

There's also a LINQ provider that translates to google's structured query operators:

var q = from r in table.AsQueryable()
        where r.IntProp > -1000 && r.StringProp == "hello"
        orderby r.IntProp
        select r;

All the other responses I see are fine, but C# has support for named groups!

I'd use the following code:

const string input = "Lorem ipsum dolor sit %download%#456 amet, consectetur adipiscing %download%#3434 elit. Duis non nunc nec mauris feugiat porttitor. Sed tincidunt blandit dui a viverra%download%#298. Aenean dapibus nisl %download%#893434 id nibh auctor vel tempor velit blandit.";

static void Main(string[] args)
{
    Regex expression = new Regex(@"%download%#(?<Identifier>[0-9]*)");
    var results = expression.Matches(input);
    foreach (Match match in results)
    {
        Console.WriteLine(match.Groups["Identifier"].Value);
    }
}

The code that reads: (?<Identifier>[0-9]*) specifies that [0-9]*'s results will be part of a named group that we index as above: match.Groups["Identifier"].Value

The copy() runs for the least length of dst and src, so you must initialize the dst to the desired length.

A := []int{1, 2, 3}
B := make([]int, 3)
copy(B, A)
C := make([]int, 2)
copy(C, A)
fmt.Println(A, B, C)

Output:

[1 2 3] [1 2 3] [1 2]

You can initialize and copy all elements in one line using append() to a nil slice.

x := append([]T{}, []...)

Example:

A := []int{1, 2, 3}
B := append([]int{}, A...)
C := append([]int{}, A[:2]...)
fmt.Println(A, B, C)    

Output:

[1 2 3] [1 2 3] [1 2]

Comparing with allocation+copy(), for greater than 1,000 elements, use append. Actually bellow 1,000 the difference may be neglected, make it a go for rule of thumb unless you have many slices.

There is indeed a Groovier Way.

if(members){
    //Some work
}

does everything if members is a collection. Null check as well as empty check (Empty collections are coerced to false). Hail Groovy Truth. :)

from row in TableA select row

Or just:

TableA

In method syntax, with other operators:

TableA.Where(row => row.IsInteresting) // no .Select(), returns the whole row.

Essentially, you already are selecting all columns, the select then transforms that to the columns you care about, so you can even do things like:

from user in Users select user.LastName+", "+user.FirstName

For anyone wishing to do this in a single line (e.g in the Display/Immediate window, a watch expression or similar in a debug session), the following will do so and "pretty print" the SQL:

new org.hibernate.jdbc.util.BasicFormatterImpl().format((new org.hibernate.loader.criteria.CriteriaJoinWalker((org.hibernate.persister.entity.OuterJoinLoadable)((org.hibernate.impl.CriteriaImpl)crit).getSession().getFactory().getEntityPersister(((org.hibernate.impl.CriteriaImpl)crit).getSession().getFactory().getImplementors(((org.hibernate.impl.CriteriaImpl)crit).getEntityOrClassName())[0]),new org.hibernate.loader.criteria.CriteriaQueryTranslator(((org.hibernate.impl.CriteriaImpl)crit).getSession().getFactory(),((org.hibernate.impl.CriteriaImpl)crit),((org.hibernate.impl.CriteriaImpl)crit).getEntityOrClassName(),org.hibernate.loader.criteria.CriteriaQueryTranslator.ROOT_SQL_ALIAS),((org.hibernate.impl.CriteriaImpl)crit).getSession().getFactory(),(org.hibernate.impl.CriteriaImpl)crit,((org.hibernate.impl.CriteriaImpl)crit).getEntityOrClassName(),((org.hibernate.impl.CriteriaImpl)crit).getSession().getEnabledFilters())).getSQLString());

...or here's an easier to read version:

new org.hibernate.jdbc.util.BasicFormatterImpl().format(
  (new org.hibernate.loader.criteria.CriteriaJoinWalker(
     (org.hibernate.persister.entity.OuterJoinLoadable)
      ((org.hibernate.impl.CriteriaImpl)crit).getSession().getFactory().getEntityPersister(
        ((org.hibernate.impl.CriteriaImpl)crit).getSession().getFactory().getImplementors(
          ((org.hibernate.impl.CriteriaImpl)crit).getEntityOrClassName())[0]),
     new org.hibernate.loader.criteria.CriteriaQueryTranslator(
          ((org.hibernate.impl.CriteriaImpl)crit).getSession().getFactory(),
          ((org.hibernate.impl.CriteriaImpl)crit),
          ((org.hibernate.impl.CriteriaImpl)crit).getEntityOrClassName(),
          org.hibernate.loader.criteria.CriteriaQueryTranslator.ROOT_SQL_ALIAS),
     ((org.hibernate.impl.CriteriaImpl)crit).getSession().getFactory(),
     (org.hibernate.impl.CriteriaImpl)crit,
     ((org.hibernate.impl.CriteriaImpl)crit).getEntityOrClassName(),
     ((org.hibernate.impl.CriteriaImpl)crit).getSession().getEnabledFilters()
   )
  ).getSQLString()
);

Notes:

1. The answer is based on the solution posted by ramdane.i.
2. It assumes the Criteria object is named crit. If named differently, do a search and replace.
3. It assumes the Hibernate version is later than 3.3.2.GA but earlier than 4.0 in order to use BasicFormatterImpl to "pretty print" the HQL. If using a different version, see this answer for how to modify. Or perhaps just remove the pretty printing entirely as it's just a "nice to have".
4. It's using getEnabledFilters rather than getLoadQueryInfluencers() for backwards compatibility since the latter was introduced in a later version of Hibernate (3.5???)
5. It doesn't output the actual parameter values used if the query is parameterized.

You need to instruct the console to clear.

For serial terminals this was typically done through so called "escape sequences", where notably the vt100 set has become very commonly supported (and its close ANSI-cousin).

Windows has traditionally not supported such sequences "out-of-the-box" but relied on API-calls to do these things. For DOS-based versions of Windows, however, the ANSI.SYS driver could be installed to provide such support.

So if you are under Windows, you need to interact with the appropriate Windows API. I do not believe the standard Java runtime library contains code to do so.

Here's an example to use ngclick & ng-if directives.

Note: that ng-if removes the element from the DOM, but ng-hide just hides the display of the element.

<!-- <input type="checkbox" ng-model="hideShow" ng-init="hideShow = false"></input> -->

<input type = "button" value = "Add Book"ng-click="hideShow=(hideShow ? false : true)"> </input>
     <div ng-app = "mainApp" ng-controller = "bookController" ng-if="hideShow">
             Enter book name: <input type = "text" ng-model = "book.name"><br>
             Enter book category: <input type = "text" ng-model = "book.category"><br>
             Enter book price: <input type = "text" ng-model = "book.price"><br>
             Enter book author: <input type = "text" ng-model = "book.author"><br>


             You are entering book: {{book.bookDetails()}}
     </div>

    <script>
             var mainApp = angular.module("mainApp", []);

             mainApp.controller('bookController', function($scope) {
                $scope.book = {
                   name: "",
                   category: "",
                   price:"",
                   author: "",


                   bookDetails: function() {
                      var bookObject;
                      bookObject = $scope.book;
                      return "Book name: " + bookObject.name +  '\n' + "Book category: " + bookObject.category + "  \n" + "Book price: " + bookObject.price + "  \n" + "Book Author: " + bookObject.author;
                   }

                };
             });
    </script>

I am able to achieve the necessary code coverage exclusions by updating jacoco-maven-plugin configuration in pom.xml

                        <exclude>**/ErrorResponse*.*</exclude>
                    </excludes>
                </configuration>
            </plugin>

this configuration excludes the GlobalExceptionHandler.java and ErrorResponse.java in the jacoco coverage.

And the following two lines does the same for sonar coverage .

    <sonar.exclusions> **/*GlobalExceptionHandler*.*, **/*ErrorResponse*.</sonar.exclusions>
        <sonar.coverage.exclusions> **/*GlobalExceptionHandler*.*, **/*ErrorResponse*.* </sonar.coverage.exclusions>

The problem with information_schema is that it can be terribly slow. It is faster to use the SHOW commands.

After you select the database you first send the query SHOW TABLES. And then you do SHOW COLUMNS for each of the tables.

In PHP that would look something like

    $res = mysqli_query("SHOW TABLES");
    while($row = mysqli_fetch_array($res))
    {   $rs2 = mysqli_query("SHOW COLUMNS FROM ".$row[0]);
        while($rw2 = mysqli_fetch_array($rs2))
        {   if($rw2[0] == $target)
               ....
        }
    }

This trick only requires one command: type net session into the command prompt.

If you are NOT an admin, you get an access is denied message.

System error 5 has occurred.

Access is denied.

If you ARE an admin, you get a different message, the most common being:

There are no entries in the list.

From MS Technet:

Used without parameters, net session displays information about all sessions with the local computer.

If (as I understand) you're trying to completely block inheritance in the web config of your child application, I suggest you to avoid using the tag in web.config. Instead create a new apppool and edit the applicationHost.config file (located in %WINDIR%\System32\inetsrv\Config and %WINDIR%\SysWOW64\inetsrv\config). You just have to find the entry for your apppool and add the attribute enableConfigurationOverride="false" like in the following example:

<add name="MyAppPool" autoStart="true" managedRuntimeVersion="v4.0" managedPipelineMode="Integrated" enableConfigurationOverride="false">
    <processModel identityType="NetworkService" />
</add>

This will avoid configuration inheritance in the applications served by MyAppPool.

In general, i.e. unlimited decimal places:

^-?(([1-9]\d*)|0)(.0*[1-9](0*[1-9])*)?$.

I created a simple plugin for YAML settings: Yettings

It works in a similar fashion to the code in khelll's answer, but you only need to add this YAML configuration file:

app/config/yetting.yml

The plugin dynamically creates a class that allows you to access the YML settings as class methods in your app like so:

Yetting.your_setting

Also, if you want to use multiple settings files with unique names, you can place them in a subdirectory inside app/config like this:

app/config/yettings/first.yml
app/config/yettings/second.yml

Then you can access the values like this:

FirstYetting.your_setting
SecondYetting.your_setting

It also provides you with default settings that can be overridden per environment. You can also use erb inside the yml file.

You shouldn't be trying to parse html with regexes see this question and how it turned out.

In the simplest terms, html is not a regular language so you can't fully parse is with regular expressions.

Having said that you can parse subsets of html when there are no similar tags nested. So as long as anything between and is not that tag itself, this will work:

preg_match("/<([\w]+)[^>]*>(.*?)<\/\1>/", $subject, $matches);
$matches = array ( [0] => full matched string [1] => tag name [2] => tag content )

A better idea is to use a parser, like the native DOMDocument, to load your html, then select your tag and get the inner html which might look something like this:

$obj = new DOMDocument();
$obj -> load($html);
$obj -> getElementByTagName('el');
$value = $obj -> nodeValue();

And since this is a proper parser it will be able to handle nesting tags etc.

Another possible solution is that the project name is not acceptable. For example, creating a project with spaces in the name does not block the project creation but the proper sources are not marked and when those are marked manually, I still was unable to create classes. Recreating the project with hyphens (-) instead of spaces corrected the problem for me.

check this link. It has helped me with errno 150: http://verysimple.com/2006/10/22/mysql-error-number-1005-cant-create-table-mydbsql-328_45frm-errno-150/

On the top of my head two things come to mind.

• Is your foreign key index a unique name in the whole database (#3 in the list)?
• Are you trying to set the table PK to NULL on update (#5 in the list)?

I'm guessing the problem is with the set NULL on update (if my brains aren't on backwards today as they so often are...).

Edit: I missed the comments on your original post. Unsigned/not unsigned int columns maybe resolved your case. Hope my link helps someone in the future thought.

After some tests, I can say the following:

• using the private interface : [UIApplication sharedApplication] will cause the app looking like it crashed, BUT it will call - (void)applicationWillTerminate:(UIApplication *)application before doing so;
• using exit(0); will also terminate the application, but it will look "normal" (the springboard's icons appears like expected, with the zoom out effect), BUT it won't call the - (void)applicationWillTerminate:(UIApplication *)application delegate method.

My advice:

1. Manually call the - (void)applicationWillTerminate:(UIApplication *)application on the delegate.
2. Call exit(0);.

Taking Shiraz's idea and running with it...

In your application, are you explicitly defining a domain User Account and Password to access AD?

When you are executing the application explicitly it may be inherently using your credentials (your currently logged in domain account) to interrogate AD. However, when calling the application from the script, I'm not sure if the application is in the System context.

A VBScript example would be as follows:

  Dim objConnection As ADODB.Connection
    Set objConnection = CreateObject("ADODB.Connection")
    objConnection.Provider = "ADsDSOObject"
    objConnection.Properties("User ID") = "MyDomain\MyAccount"
    objConnection.Properties("Password") = "MyPassword"
    objConnection.Open "Active Directory Provider"

If this works, of course it would be best practice to create and use a service account specifically for this task, and to deny interactive login to that account.

Interestingly, if you're just typing at the python interactive interpreter, you have to follow a function with a blank line. This does not work:

def foo(x):
  return x+1
print "last"

although it is perfectly legal python syntax in a file. There are other syntactic differences when typing to the interpreter too, so beware.

Here's a more portable version (just for fun, it is not necessary in your case):

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from subprocess import Popen, PIPE, STDOUT

try:
    from subprocess import DEVNULL # py3k
except ImportError:
    import os
    DEVNULL = open(os.devnull, 'wb')

text = u"René Descartes"
p = Popen(['espeak', '-b', '1'], stdin=PIPE, stdout=DEVNULL, stderr=STDOUT)
p.communicate(text.encode('utf-8'))
assert p.returncode == 0 # use appropriate for your program error handling here

For using DOSBox with SDL, you will need to set or change the following:

[sdl]
windowresolution=1280x960
output=opengl

Here is three options to put those settings:

1. Edit user's default configuration, for example, using vi:

   $ dosbox -printconf
   /home/USERNAME/.dosbox/dosbox-0.74.conf
   $ vi "$(dosbox -printconf)"
   $ dosbox
   

2. For temporary resize, create a new configuration with the three lines above, say newsize.conf:

   $ dosbox -conf newsize.conf
   

   You can use -conf to load multiple configuration and/or with -userconf for default configuration, for example:

   $ dosbox -userconf -conf newsize.conf 
   [snip]
   ---
   CONFIG:Loading primary settings from config file /home/USERNAME/.dosbox/dosbox-0.74.conf
   CONFIG:Loading additional settings from config file newsize.conf
   [snip]
   

3. Create a dosbox.conf under current directory, DOSBox loads it as default.

DOSBox should start up and resize to 1280x960 in this case.

Note that you probably would not get any size you desired, for instance, I set 1280x720 and I got 1152x720.

There are two storage areas involved: the stack and the heap.The stack is where the current state of a method call is kept (ie local variables and references), and the heap is where objects are stored. recursion and memory

I gues there are too many keys in the counter dict that will consume too much memory of the heap region, so the Python runtime will raise a OutOfMemory exception.

To save it, don't create a giant object, e.g. the counter.

1.StackOverflow

a program that create too many local variables.

Python 2.7.9 (default, Mar  1 2015, 12:57:24)

... 
>>> f.write('foo()')
>>> f.close()
>>> execfile('stack_overflow.py')
Killed

2.OutOfMemory

a program that creats a giant dict includes too many keys.

>>> f = open('out_of_memory.py','w')
>>> f.write('def foo():\n')
>>> f.write('\tcounter = {}\n')
>>> for x in xrange(10000000):
...   f.write('counter[%d] = %d\n' % (x, x))
... 
>>> f.write('foo()\n')
>>> f.close()
>>> execfile('out_of_memory.py')
Killed

• 7. Memory : Stack vs Heap
• recursion and memory

With df.plot()

Normally when quickly plotting a DataFrame, I use pd.DataFrame.plot(). This takes the index as the x value, the value as the y value and plots each column separately with a different color. A DataFrame in this form can be achieved by using set_index and unstack.

import matplotlib.pyplot as plt
import pandas as pd

carat = [5, 10, 20, 30, 5, 10, 20, 30, 5, 10, 20, 30]
price = [100, 100, 200, 200, 300, 300, 400, 400, 500, 500, 600, 600]
color =['D', 'D', 'D', 'E', 'E', 'E', 'F', 'F', 'F', 'G', 'G', 'G',]

df = pd.DataFrame(dict(carat=carat, price=price, color=color))

df.set_index(['color', 'carat']).unstack('color')['price'].plot(style='o')
plt.ylabel('price')

With this method you do not have to manually specify the colors.

This procedure may make more sense for other data series. In my case I have timeseries data, so the MultiIndex consists of datetime and categories. It is also possible to use this approach for more than one column to color by, but the legend is getting a mess.

Well, the important point it seems here is that svcutil is not available by default from command line, you can run it from the vs xommand line shortcut but if you make a batch file normally that wont help unless you run the vcvarsall.bat file before the script. Below is a sample

"C:\Program Files\Microsoft Visual Studio *version*\VC\vcvarsall.bat"
svcutil.exe /language:cs /out:generatedProxy.cs /config:app.config http://localhost:8000/ServiceModelSamples/service

find supports wildcard matches, just add a *:

find / -type d -name "ora10*"

OAuth is an open standard for authorization, commonly used as a way for Internet users to log into third party websites using their Microsoft, Google, Facebook or Twitter accounts without exposing their password.

And you can use HTML5's autofocus attribute (works in all current browsers except IE9 and below). Only call your script if it's IE9 or earlier, or an older version of other browsers.

<input type="text" name="fname" autofocus>

Turn the Pluralization On. The problem is that you model object are using singular name (Pupil) convention, while in your database you are using pluralized names Pupils with s.

UPDATE

This post shows how can you turn it on or off. Some relevant excerpt of that post:

To turn pluralization on and off

• On the Tools menu, click Options.

• In the Options dialog box, expand Database Tools. Note: Select Show all settings if the Database Tools node is not visible.

• Click O/R Designer.

• Set Pluralization of names to Enabled = False to set the O/R Designer so that it does not change class names.

• Set Pluralization of names to Enabled = True to apply pluralization rules to the class names of objects added to the O/R Designer.

UPDATE 2

But note that, you should avoid pluralized names. You can read here how to do it (I'll cite it here, just in case the link gets broken).

(...) When you work with Entity Framework Code First approach, you are creating your database tables from your model classes. Usually Entity Framework will create tables with Pluralized names. that means if you have a model class called PhoneNumber, Entity framework will create a table for this class called “PhoneNumbers“. If you wish to avoid pluralized name and wants singular name like Customer , you can do it like this In your DBContext class, Override the “OnModelCreating” method like this (...)

(...) Having this Method Overriding will avoid creating tables with pluralized names. Now it will create a Table called “PhoneNumber” , Not “PhoneNumbers” (...)

Using suggestions from others, I think I got it to work:

(using SDK v1 R2)

It's not perfect, since i need to delete the entire conversation, but for our purposes, it's a sufficient compromise as we will at least know all messages will be looked at and verified. Our flow will probably need to then listen for the message, capture for the message we want, do a query to get the thread_id of the recently inbounded message and do the delete() call.

In our Activity:

Uri uriSms = Uri.parse("content://sms/inbox");
Cursor c = getContentResolver().query(uriSms, null,null,null,null); 
int id = c.getInt(0);
int thread_id = c.getInt(1); //get the thread_id
getContentResolver().delete(Uri.parse("content://sms/conversations/" + thread_id),null,null);

Note: I wasn't able to do a delete on content://sms/inbox/ or content://sms/all/

Looks like the thread takes precedence, which makes sense, but the error message only emboldened me to be angrier. When trying the delete on sms/inbox/ or sms/all/, you will probably get:

java.lang.IllegalArgumentException: Unknown URL
    at com.android.providers.telephony.SmsProvider.delete(SmsProvider.java:510)
    at android.content.ContentProvider$Transport.delete(ContentProvider.java:149)
    at android.content.ContentProviderNative.onTransact(ContentProviderNative.java:149)

For additional reference too, make sure to put this into your manifest for your intent receiver:

<receiver android:name=".intent.MySmsReceiver">
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED"></action>
    </intent-filter>
</receiver>

Note the receiver tag does not look like this:

<receiver android:name=".intent.MySmsReceiver" 
    android:permission="android.permission.RECEIVE_SMS">

When I had those settings, android gave me some crazy permissions exceptions that didn't allow android.phone to hand off the received SMS to my intent. So, DO NOT put that RECEIVE_SMS permission attribute in your intent! Hopefully someone wiser than me can tell me why that was the case.

If you use psycopg2 (and possibly some other client library), you can simply pass a Python datetime object as a parameter to a SQL-query:

from datetime import datetime, timezone

dt = datetime.now(timezone.utc)
cur.execute('INSERT INTO mytable (mycol) VALUES (%s)', (dt,))

(This assumes that the timestamp with time zone type is used on the database side.)

More Python types that can be adapted into SQL (and returned as Python objects when a query is executed) are listed here.

I solved the issue by simply deleting my whole /build folder and rebuilding (menu Build > rebuild project).

public class MyObject implements Cloneable, Serializable{   

    @Override
    @SuppressWarnings(value = "unchecked")
    protected MyObject clone(){
        ObjectOutputStream oos = null;
        ObjectInputStream ois = null;
        try {
            ByteArrayOutputStream bOs = new ByteArrayOutputStream();
            oos = new ObjectOutputStream(bOs);
            oos.writeObject(this);
            ois = new ObjectInputStream(new ByteArrayInputStream(bOs.toByteArray()));
            return  (MyObject)ois.readObject();

        } catch (Exception e) {
            //Some seriouse error :< //
            return null;
        }finally {
            if (oos != null)
                try {
                    oos.close();
                } catch (IOException e) {

                }
            if (ois != null)
                try {
                    ois.close();
                } catch (IOException e) {

                }
        }
    }
}

MySQL function example:

Open the mysql terminal:

el@apollo:~$ mysql -u root -pthepassword yourdb
mysql>

Drop the function if it already exists

mysql> drop function if exists myfunc;
Query OK, 0 rows affected, 1 warning (0.00 sec)

Create the function

mysql> create function hello(id INT)
    -> returns CHAR(50)
    -> return 'foobar';
Query OK, 0 rows affected (0.01 sec)

Create a simple table to test it out with

mysql> create table yar (id INT);
Query OK, 0 rows affected (0.07 sec)

Insert three values into the table yar

mysql> insert into yar values(5), (7), (9);
Query OK, 3 rows affected (0.04 sec)
Records: 3  Duplicates: 0  Warnings: 0

Select all the values from yar, run our function hello each time:

mysql> select id, hello(5) from yar;
+------+----------+
| id   | hello(5) |
+------+----------+
|    5 | foobar   |
|    7 | foobar   |
|    9 | foobar   |
+------+----------+
3 rows in set (0.01 sec)

Verbalize and internalize what just happened:

You created a function called hello which takes one parameter. The parameter is ignored and returns a CHAR(50) containing the value 'foobar'. You created a table called yar and added three rows to it. The select statement runs the function hello(5) for each row returned by yar.

In Python 3, you can use

"one" in d.values()

to test if "one" is among the values of your dictionary.

In Python 2, it's more efficient to use

"one" in d.itervalues()

instead.

Note that this triggers a linear scan through the values of the dictionary, short-circuiting as soon as it is found, so this is a lot less efficient than checking whether a key is present.

$('div[id ^= "player_"]');

This worked for me..select all Div starts with "players_" keyword and display it.

Short and sweet:

def remove_prefix(text, prefix):
    return text[text.startswith(prefix) and len(prefix):]

You should have a look at Boost.Python. Here is the short introduction taken from their website:

The Boost Python Library is a framework for interfacing Python and C++. It allows you to quickly and seamlessly expose C++ classes functions and objects to Python, and vice-versa, using no special tools -- just your C++ compiler. It is designed to wrap C++ interfaces non-intrusively, so that you should not have to change the C++ code at all in order to wrap it, making Boost.Python ideal for exposing 3rd-party libraries to Python. The library's use of advanced metaprogramming techniques simplifies its syntax for users, so that wrapping code takes on the look of a kind of declarative interface definition language (IDL).

Have appended the html in componentDidMount using jQuery append. This should solve the problem.

 var MyComponent = React.createClass({
    render: function() {

        return (
           <div>

           </div>
        );
    },
    componentDidMount() {
        $(ReactDOM.findDOMNode(this)).append(this.props.text);
    }
});

Yes, you are correct. If you are using a jQuery plugin, do not put the code in the controller. Instead create a directive and put the code that you would normally have inside the link function of the directive.

There are a couple of points in the documentation that you could take a look at. You can find them here:
Common Pitfalls

Using controllers correctly

Ensure that when you are referencing the script in your view, you refer it last - after the angularjs library, controllers, services and filters are referenced.

EDIT: Rather than using $(element), you can make use of angular.element(element) when using AngularJS with jQuery

The c variable already contains the char code!

"string".each_byte do |c|
    puts c
end

yields

115
116
114
105
110
103

Use a for loop to iterate through your array. For each string, create a new option element, assign the string as its innerHTML and value, and then append it to the select element.

var cuisines = ["Chinese","Indian"];     
var sel = document.getElementById('CuisineList');
for(var i = 0; i < cuisines.length; i++) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisines[i];
    opt.value = cuisines[i];
    sel.appendChild(opt);
}

DEMO

UPDATE: Using createDocumentFragment and forEach

If you have a very large list of elements that you want to append to a document, it can be non-performant to append each new element individually. The DocumentFragment acts as a light weight document object that can be used to collect elements. Once all your elements are ready, you can execute a single appendChild operation so that the DOM only updates once, instead of n times.

var cuisines = ["Chinese","Indian"];     

var sel = document.getElementById('CuisineList');
var fragment = document.createDocumentFragment();

cuisines.forEach(function(cuisine, index) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisine;
    opt.value = cuisine;
    fragment.appendChild(opt);
});

sel.appendChild(fragment);

DEMO

For me Visual Studio had created a projectname.v11 of type "Visual Studio Solution User Options". I deleted this file and restarted and everything was fine.

Another solution that I would consider is using K9S which is a great kube administration tool.

After installation, the usage is very straightforward:

 k9s -n my-namespace --context the_context_name_in_kubeconfig

(If kubeconfig is not in the default location add KUBECONFIG=path/to/kubeconfig prefix).

The default view will list all pods as a list:

We can change the view to other Kube controllers like replica set (question asked for replication controllers so notice they are deprecated), deployments, cron jobs, etc' by entering a colon : and start typing the desired controller - as we can see K9S provides autocompletion for us:

And we can see all replica sets in the current namespace:

We can just choose the desired replica set by clicking enter and then we'll see the list of all pods which are related to this replica set - we can then press on 'l' to view logs of each pod.

So, unlike in the case of stern, we still need to go on each pod and view its logs but I think it is very convenient with K9S - we first view all pods of a related controller and then investigate logs of each pod by simply navigating with enter, l and escape.

Veverke mentioned that it is possible to disable generation of binding redirects by setting AutoGEneratedBindingRedirects to false. Not sure if it's a new thing since this question was posted, but there is an "Skip applying binding redirects" option in Tools/Options/Nuget Packet Manager, which can be toggled. By default it is off, meaning the redirects will be applied. However if you do this, you will have to manage any necessary binding redirects manually.

As described in the IPv6 Wikipedia article,

IPv6 addresses are normally written as eight groups of four hexadecimal digits, where each group is separated by a colon (:)

A typical IPv6 address:

2001:0db8:85a3:0000:0000:8a2e:0370:7334

This is 39 characters long. IPv6 addresses are 128 bits long, so you could conceivably use a binary(16) column, but I think I'd stick with an alphanumeric representation.

Instructions to install from private repo using ssh credentials:

$ pip install git+ssh://[email protected]/myuser/foo.git@my_version

In my case, I forgot (' or ") at the end of string. E.g 'ABC' or "ABC"

Just to be clear, This still have to be tested more...

public class Splitter {

public static <T> List<List<T>> splitList(List<T> listTobeSplit, int size) {
    List<List<T>> sublists= new LinkedList<>();
    if(listTobeSplit.size()>size) {
    int counter=0;
    boolean lastListadded=false;

    List<T> subList=new LinkedList<>();

    for(T t: listTobeSplit) {           
         if (counter==0) {               
             subList =new LinkedList<>();
             subList.add(t);
             counter++;
             lastListadded=false;
         }
         else if(counter>0 && counter<size-1) {
             subList.add(t);
             counter++;
         }
         else {
             lastListadded=true;
             subList.add(t);
             sublists.add(subList);
             counter=0;
         }              
    }
    if(lastListadded==false)
        sublists.add(subList);      
    }
    else {
        sublists.add(listTobeSplit);
    }
    log.debug("sublists: "+sublists);
    return sublists;
 }
}

Example: say you have an 'image' you want to scale you will need a bufferedImage probably, and probably will be starting out with just 'Image' object. So this works I think... The AVATAR_SIZE is the target width we want our image to be:

Image imgData = image.getScaledInstance(Constants.AVATAR_SIZE, -1, Image.SCALE_SMOOTH);     

BufferedImage bufferedImage = new BufferedImage(imgData.getWidth(null), imgData.getHeight(null), BufferedImage.TYPE_INT_RGB);

bufferedImage.getGraphics().drawImage(imgData, 0, 0, null);

If the replacement character can be '?' instead of a space, then I'd suggest result = text.encode('ascii', 'replace').decode():

"""Test the performance of different non-ASCII replacement methods."""


import re
from timeit import timeit


# 10_000 is typical in the project that I'm working on and most of the text
# is going to be non-ASCII.
text = 'Æ' * 10_000


print(timeit(
    """
result = ''.join([c if ord(c) < 128 else '?' for c in text])
    """,
    number=1000,
    globals=globals(),
))

print(timeit(
    """
result = text.encode('ascii', 'replace').decode()
    """,
    number=1000,
    globals=globals(),
))

Results:

0.7208260721400134
0.009975979187503592

According to this discussion, Promise has finally been called CompletableFuture for inclusion in Java 8, and its javadoc explains:

A Future that may be explicitly completed (setting its value and status), and may be used as a CompletionStage, supporting dependent functions and actions that trigger upon its completion.

An example is also given on the list:

f.then((s -> aStringFunction(s)).thenAsync(s -> ...);

Note that the final API is slightly different but allows similar asynchronous execution:

CompletableFuture<String> f = ...;
f.thenApply(this::modifyString).thenAccept(System.out::println);

The solution can be achieved in two ways

1. Using display:table and display:table-cell
2. Using padding and negative margin.

The classes which are used to obtain the above solution are not provided in bootstrap 3. display:table and display:table-cell are given but only when using tables in HTML. negative margin and padding classes are also not there.

Hence we have to use custom css to achieve this.

The below is the first solution

I had a similar issue when migrating over to React-Router v4 so I'll try to explain my solution below.

Please do not consider this answer as the right way to solve the problem, I imagine there's a good chance something better will arise as React Router v4 becomes more mature and leaves beta (It may even already exist and I just didn't discover it).

For context, I had this problem because I occasionally use Redux-Saga to programmatically change the history object (say when a user successfully authenticates).

In the React Router docs, take a look at the <Router> component and you can see you have the ability to pass your own history object via a prop. This is the essence of the solution - we supply the history object to React-Router from a global module.

Steps:

1. Install the history npm module - yarn add history or npm install history --save

2. create a file called history.js in your App.js level folder (this was my preference)

   // src/history.js
   
   import createHistory from 'history/createBrowserHistory';
   export default createHistory();`
   

3. Add this history object to your Router component like so

   // src/App.js
   
   import history from '../your/path/to/history.js;'
   <Router history={history}>
   // Route tags here
   </Router>
   

4. Adjust the URL just like before by importing your global history object:

   import history from '../your/path/to/history.js;'
   history.push('new/path/here/');
   

Everything should stay synced up now, and you also have access to a way of setting the history object programmatically and not via a component/container.

=IF(INDEX(a,b,c)="0","", INDEX(a,b,c)) worked for me with a minor modification. Excluding the 0 and no spaces in between quotations: =IF(INDEX(a,b,c)="","", INDEX(a,b,c))

Yes you can do that.

Materials you need:

1. WebServer
2. A Database Stored in the webserver
3. And a little bit android knowledge :)
4. Webservices (json ,Xml...etc) whatever you are comfortable with

1. First set the internet permissions in your manifest file

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

2. Make a class to make an HTTPRequest from the server (i am using json parisng to get the values)

for eg:

    public class JSONfunctions {

    public static JSONObject getJSONfromURL(String url) {
        InputStream is = null;
        String result = "";
        JSONObject jArray = null;

        // Download JSON data from URL
        try {
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(url);
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();
            is = entity.getContent();

        } catch (Exception e) {
            Log.e("log_tag", "Error in http connection " + e.toString());
        }

        // Convert response to string
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            result = sb.toString();
        } catch (Exception e) {
            Log.e("log_tag", "Error converting result " + e.toString());
        }

        try {

            jArray = new JSONObject(result);
        } catch (JSONException e) {
            Log.e("log_tag", "Error parsing data " + e.toString());
        }

        return jArray;
    }
}

3. In your MainActivity Make an object of the class JsonFunctions and pass the url as an argument from where you want to get the data

eg:

JSONObject jsonobject;

jsonobject = JSONfunctions.getJSONfromURL("http://YOUR_DATABASE_URL");

4. And then finally read the jsontags and store the values in an arraylist and later show it in listview if you want

and if you have any problem you can follow this blog he gives excellent android tutorials AndroidHive

Since the above answer i wrote was long back and now HttpClient, HttpPost,HttpEntity have been removed in Api 23. You can use the below code in the build.gradle(app-level) to still continue using org.apache.httpin your project.

android {
    useLibrary 'org.apache.http.legacy'
    signingConfigs {}
    buildTypes {}
}

or You can use HttpURLConnection like below to get your response from server

public String getJSON(String url, int timeout) {
HttpURLConnection c = null;
try {
    URL u = new URL(url);
    c = (HttpURLConnection) u.openConnection();
    c.setRequestMethod("GET");
    c.setRequestProperty("Content-length", "0");
    c.setUseCaches(false);
    c.setAllowUserInteraction(false);
    c.setConnectTimeout(timeout);
    c.setReadTimeout(timeout);
    c.connect();
    int status = c.getResponseCode();

    switch (status) {
        case 200:
        case 201:
            BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
            StringBuilder sb = new StringBuilder();
            String line;
            while ((line = br.readLine()) != null) {
                sb.append(line+"\n");
            }
            br.close();
            return sb.toString();
    }

} catch (MalformedURLException ex) {
    Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
    Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
} finally {
   if (c != null) {
      try {
          c.disconnect();
      } catch (Exception ex) {
         Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
      }
   }
}
return null;

}

or You can use 3rd party Library like Volley, Retrofit to call the webservice api and get the response and later parse it with using FasterXML-jackson, google-gson.

The original code is a bit cumbersome and you might want to use the collections.deque instead if you want to use BFS to find if a path exists between 2 points on the graph. Here is a quick solution I hacked up:

Note: this method might continue infinitely if there exists no path between the two nodes. I haven't tested all cases, YMMV.

from collections import deque

# a sample graph
  graph = {'A': ['B', 'C','E'],
           'B': ['A','C', 'D'],
           'C': ['D'],
           'D': ['C'],
           'E': ['F','D'],
           'F': ['C']}

   def BFS(start, end):
    """ Method to determine if a pair of vertices are connected using BFS

    Args:
      start, end: vertices for the traversal.

    Returns:
      [start, v1, v2, ... end]
    """
    path = []
    q = deque()
    q.append(start)
    while len(q):
      tmp_vertex = q.popleft()
      if tmp_vertex not in path:
        path.append(tmp_vertex)

      if tmp_vertex == end:
        return path

      for vertex in graph[tmp_vertex]:
        if vertex not in path:
          q.append(vertex)

I had an issue at work. The oracle server was "patched" and one of the databases I use could not be connect via the TNSNames entry but via Basic connection. The Database was up and admin could see it was up and running.

Addionally any application that used TNS for connecting to the database would not work either.

The problem found was that the database name was not correct in the TNS file but for some reason it's been working for years. Correcting the name fixed it for us. I did find that Oracle SQL Developer kept using the old TNS entry even after I updated it and I don't feel like reinstalling it for just one DB Connection. It appears that when the database was created it was given a smaller name then the others and via some cut and paste action within the TNSNames file it got mixed up. No one is sure how its worked as we're investigating it but the oracle patch ensured that the name had to be correct

An example of the name was it was down as "DBName.Part1.Part2" but in fact the DB name was "DBName"

I've used these techniques before and they both work well. If you read the pros/cons of each you can decide which is right for your site.

Alternatively you could use the full size background image jQuery plugin if you want to get away from the bugs in the above.

I'm using: Win Server 2012 R2 / IIS 8.5 / MVC4 / .Net 4.5

If none of the above worked then try this:

Uncheck "Precompile during Publishing"

This kicked my butt for a few days.

I had a similar requirement, and had to do it it basic CSS and JavaScript. No JQuery available.

This is what I got working.

<html>
      <head>
            <style>
                   img {
                          max-width: 95% !important;
                          max-height: 95% !important;
                       }
            </style>
            <script>
                   function FitImagesToScreen() {
                      var images = document.getElementsByTagName('img');
                      if(images.length > 0){
                         for(var i=0; i < images.length; i++){
                             if(images[i].width >= (window.innerWidth - 10)){
                                 images[i].style.width = 'auto';
                               }
                            }
                         }
                   }
             </script>
      </head>
      <body onload='FitImagesToScreen()'>
      ----    
      </body>
</html>

Note : I haven't used 100% for image width as there was always a bit of padding to be considered.

You can do it now with HTML5

In essence you use the multiple attribute on the file input.

<input type='file' multiple>

var str = "0000000...0000";
var arr = str.split("");

usage in expressions: arr[i]*1;

EDIT: if arr supposed to be used in integer expressions, then please don't mind the char value of '0'. You just use it as follows: a = a * arr[i] (assuming a has integer value).

Late answer, but two things to add:

• For information on how to change the 'ColorOrder' property and how to set a global default with 'DefaultAxesColorOrder', see the "Appendix" at the bottom of this post.
• There is a great tool on the MATLAB Central File Exchange to generate any number of visually distinct colors, if you have the Image Processing Toolbox to use it. Read on for details.

The ColorOrder axes property allows MATLAB to automatically cycle through a list of colors when using hold on/all (again, see Appendix below for how to set/get the ColorOrder for a specific axis or globally via DefaultAxesColorOrder). However, by default MATLAB only specifies a short list of colors (just 7 as of R2013b) to cycle through, and on the other hand it can be problematic to find a good set of colors for more data series. For 10 plots, you obviously cannot rely on the default ColorOrder.

A great way to define N visually distinct colors is with the "Generate Maximally Perceptually-Distinct Colors" (GMPDC) submission on the MATLAB Central File File Exchange. It is best described in the author's own words:

This function generates a set of colors which are distinguishable by reference to the "Lab" color space, which more closely matches human color perception than RGB. Given an initial large list of possible colors, it iteratively chooses the entry in the list that is farthest (in Lab space) from all previously-chosen entries.

For example, when 25 colors are requested:

The GMPDC submission was chosen on MathWorks' official blog as Pick of the Week in 2010 in part because of the ability to request an arbitrary number of colors (in contrast to MATLAB's built in 7 default colors). They even made the excellent suggestion to set MATLAB's ColorOrder on startup to,

distinguishable_colors(20)

Of course, you can set the ColorOrder for a single axis or simply generate a list of colors to use in any way you like. For example, to generate 10 "maximally perceptually-distinct colors" and use them for 10 plots on the same axis (but not using ColorOrder, thus requiring a loop):

% Starting with X of size N-by-P-by-2, where P is number of plots
mpdc10 = distinguishable_colors(10) % 10x3 color list
hold on
for ii=1:size(X,2),
    plot(X(:,ii,1),X(:,ii,2),'.','Color',mpdc10(ii,:));
end

The process is simplified, requiring no for loop, with the ColorOrder axis property:

% X of size N-by-P-by-2
mpdc10 = distinguishable_colors(10)
ha = axes; hold(ha,'on')
set(ha,'ColorOrder',mpdc10)    % --- set ColorOrder HERE ---
plot(X(:,:,1),X(:,:,2),'-.')   % loop NOT needed, 'Color' NOT needed. Yay!

APPENDIX

To get the ColorOrder RGB array used for the current axis,

get(gca,'ColorOrder')

To get the default ColorOrder for new axes,

get(0,'DefaultAxesColorOrder')

Example of setting new global ColorOrder with 10 colors on MATLAB start, in startup.m:

set(0,'DefaultAxesColorOrder',distinguishable_colors(10))

I think in the question and in some of the answers there is a bit of confusion about the meaning of this pseudocode in DOS: IF A IF B X ELSE Y. It does not mean IF(A and B) THEN X ELSE Y, but in fact means IF A( IF B THEN X ELSE Y). If the test of A fails, then he whole of the inner if-else will be ignored.

As one of the answers mentioned, in this case only one of the tests can succeed so the 'else' is not needed, but of course that only works in this example, it isn't a general solution for doing if-else.

There are lots of ways around this. Here is a few ideas, all are quite ugly but hey, this is (or at least was) DOS!

@echo off

set one=1
set two=2

REM Example 1

IF %one%_%two%==1_1 (
   echo Example 1 fails
) ELSE IF %one%_%two%==1_2 (
   echo Example 1 works correctly
) ELSE (
    echo Example 1 fails
)

REM Example 2

set test1result=0
set test2result=0

if %one%==1 if %two%==1 set test1result=1
if %one%==1 if %two%==2 set test2result=1

IF %test1result%==1 (
   echo Example 2 fails
) ELSE IF %test2result%==1 (
   echo Example 2 works correctly
) ELSE (
    echo Example 2 fails
)

REM Example 3

if %one%==1 if %two%==1 (
   echo Example 3 fails
   goto :endoftests
)
if %one%==1 if %two%==2 (
   echo Example 3 works correctly
   goto :endoftests
)
echo Example 3 fails
)
:endoftests

The URL file://[servername]/[sharename] should open an explorer window to the shared folder on the network.

To use copying with xargs to directories using wildcards on Mac OS, the only solution that worked for me with spaces in the directory name is:

find ./fs*/* -type d -print0 | xargs -0 -n 1 cp test 

Where test is the file to copy
And ./fs*/* the directories to copy to

The problem is that xargs sees spaces as a new argument, the solutions to change the delimiter character using -d or -E is unfortunately not properly working on Mac OS.

This works quite well in my local.py, saves me messing up the regular logging:

from .settings import *

LOGGING['handlers']['console'] = {
    'level': 'DEBUG',
    'class': 'logging.StreamHandler',
    'formatter': 'verbose'
}
LOGGING['loggers']['foo.bar'] = {
    'handlers': ['console'],
    'propagate': False,
    'level': 'DEBUG',
}

You need to open the file in append mode, by setting "a" or "ab" as the mode. See open().

When you open with "a" mode, the write position will always be at the end of the file (an append). You can open with "a+" to allow reading, seek backwards and read (but all writes will still be at the end of the file!).

Example:

>>> with open('test1','wb') as f:
        f.write('test')
>>> with open('test1','ab') as f:
        f.write('koko')
>>> with open('test1','rb') as f:
        f.read()
'testkoko'

Note: Using 'a' is not the same as opening with 'w' and seeking to the end of the file - consider what might happen if another program opened the file and started writing between the seek and the write. On some operating systems, opening the file with 'a' guarantees that all your following writes will be appended atomically to the end of the file (even as the file grows by other writes).

A few more details about how the "a" mode operates (tested on Linux only). Even if you seek back, every write will append to the end of the file:

>>> f = open('test','a+') # Not using 'with' just to simplify the example REPL session
>>> f.write('hi')
>>> f.seek(0)
>>> f.read()
'hi'
>>> f.seek(0)
>>> f.write('bye') # Will still append despite the seek(0)!
>>> f.seek(0)
>>> f.read()
'hibye'

In fact, the fopen manpage states:

Opening a file in append mode (a as the first character of mode) causes all subsequent write operations to this stream to occur at end-of-file, as if preceded the call:

fseek(stream, 0, SEEK_END);

Old simplified answer (not using with):

Example: (in a real program use with to close the file - see the documentation)

>>> open("test","wb").write("test")
>>> open("test","a+b").write("koko")
>>> open("test","rb").read()
'testkoko'

To iterate over all the key-value pairs in a table you can use pairs:

for k, v in pairs(arr) do
  print(k, v[1], v[2], v[3])
end

outputs:

pears   2   p   green
apples  0   a   red
oranges 1   o   orange

Edit: Note that Lua doesn't guarantee any iteration order for the associative part of the table. If you want to access the items in a specific order, retrieve the keys from arr and sort it. Then access arr through the sorted keys:

local ordered_keys = {}

for k in pairs(arr) do
    table.insert(ordered_keys, k)
end

table.sort(ordered_keys)
for i = 1, #ordered_keys do
    local k, v = ordered_keys[i], arr[ ordered_keys[i] ]
    print(k, v[1], v[2], v[3])
end

outputs:

  apples  a   red     5
  oranges o   orange  12
  pears   p   green   7

IF EXISTS (SELECT * FROM sys.types WHERE is_table_type = 1 AND name = 'MyType')

Update, Mar 2013

You can use TYPE_ID too

git pull prints Already up-to-date

solution:

you might be created a repository/project in remote(server) and added some file there, Then again created a Folder in your local and initialised git git init - this is the mistake, you should not create git init in local, instead clone the project to your local using git clone

then pull

Using String#gsub with regular expression:

"((String1))".gsub(/^\(+|\)+$/, '')
# => "String1"
"(((((( parentheses )))".gsub(/^\(+|\)+$/, '')
# => " parentheses "

This will remove surrounding parentheses only.

"(((((( This (is) string )))".gsub(/^\(+|\)+$/, '')
# => " This (is) string "

Before understanding JSONP, you need to know JSON format and XML. Currently the most frequently used data format on the web is XML, but XML is very complicated. It makes users inconvenient to process embedded in Web pages.

To make JavaScript can easily exchange data, even as the data processing program, we use the wording according to JavaScript objects and developed a simple data exchange format, which is JSON. JSON can be used as data, or as a JavaScript program.

JSON can be directly embedded in JavaScript, using them you can directly execute certain JSON program, but due to security constraints, the browser Sandbox mechanism disables cross-domain JSON code execution.

To make JSON can be passed after the execution, we developed a JSONP. JSONP bypass the security limits of the browser with JavaScript Callback functionality and the < script > tag.

So in short it explains what JSONP is, what problem it solves (when to use it).

2 GB by default. If the application is large address space aware (linked with /LARGEADDRESSAWARE), it gets 4 GB (not 3 GB, see http://msdn.microsoft.com/en-us/library/aa366778.aspx)

They're still limited to 2 GB since many application depends on the top bit of pointers to be zero.

How about the following one? Should allow you to use either raw_input or input in both Python2 and Python3 with the semantics of Python2's raw_input (aka the semantics of Python3's input)

# raw_input isn't defined in Python3.x, whereas input wasn't behaving like raw_input in Python 2.x
# this should make both input and raw_input work in Python 2.x/3.x like the raw_input from Python 2.x 
try: input = raw_input
except NameError: raw_input = input

Following worked for me in JSON config file:

"scripts": {
  "start": "webpack-dev-server --host 127.0.0.1 --port 80 ./js/index.js"
},

Unfortunately GIT commands like prune and reset or push didn't work for me. Prune worked once and then the issue returned.

The permanent solution which worked for me is to edit a git file manually. Just go to the project's .git folder and then open the file packed-refs in a text editor like Notepad++. Then navigate to the row with the failing branch and update its guid to the expected one.

If you have a message like:

error: cannot lock ref 'refs/remotes/origin/feature/branch_xxx': is at 425ea23facf96f51f412441f41ad488fc098cf23 but expected 383de86fed394ff1a1aeefc4a522d886adcecd79

then in the file find the row with refs/remotes/origin/feature/branch_xxx. The guid there will be the expected (2nd) one - 383de86fed394ff1a1aeefc4a522d886adcecd79. You need to change it to the real (1st) one - 425ea23facf96f51f412441f41ad488fc098cf23.

Repeat for the other failing branches and you'll be good to proceed. Sometimes after re-fetch I had to repeat for the same branches which i already 'fixed' earlier. On re-fetch GIT updates guids and gives you the latest one.

Anyways the issue isn't a show stopper. The branch list gets updated. This is rather a warning.

For your iphone You could use in your head balise :

"width=device-width"

Rebase and Cherry-pick is the only way you can keep clean commit history. Avoid using merge and avoid creating merge conflict. If you are using gerrit set one project to Merge if necessary and one project to cherry-pick mode and try yourself.

The answers seem a bit dated, they don't work for me. What did work was

I've posted a step-by-step procedure for creating a Windows service in C# here. It sounds like you're at least to this point, and now you're wondering how to start the service once it is installed. Setting the StartType property to Automatic will cause the service to start automatically after rebooting your system, but it will not (as you've discovered) automatically start your service after installation.

I don't remember where I found it originally (perhaps Marc Gravell?), but I did find a solution online that allows you to install and start your service by actually running your service itself. Here's the step-by-step:

1. Structure the Main() function of your service like this:

   static void Main(string[] args)
   {
       if (args.Length == 0) {
           // Run your service normally.
           ServiceBase[] ServicesToRun = new ServiceBase[] {new YourService()};
           ServiceBase.Run(ServicesToRun);
       } else if (args.Length == 1) {
           switch (args[0]) {
               case "-install":
                   InstallService();
                   StartService();
                   break;
               case "-uninstall":
                   StopService();
                   UninstallService();
                   break;
               default:
                   throw new NotImplementedException();
           }
       }
   }
   

2. Here is the supporting code:

   using System.Collections;
   using System.Configuration.Install;
   using System.ServiceProcess;
   
   private static bool IsInstalled()
   {
       using (ServiceController controller = 
           new ServiceController("YourServiceName")) {
           try {
               ServiceControllerStatus status = controller.Status;
           } catch {
               return false;
           }
           return true;
       }
   }
   
   private static bool IsRunning()
   {
       using (ServiceController controller = 
           new ServiceController("YourServiceName")) {
           if (!IsInstalled()) return false;
           return (controller.Status == ServiceControllerStatus.Running);
       }
   }
   
   private static AssemblyInstaller GetInstaller()
   {
       AssemblyInstaller installer = new AssemblyInstaller(
           typeof(YourServiceType).Assembly, null);
       installer.UseNewContext = true;
       return installer;
   }
   

3. Continuing with the supporting code...

   private static void InstallService()
   {
       if (IsInstalled()) return;
   
       try {
           using (AssemblyInstaller installer = GetInstaller()) {
               IDictionary state = new Hashtable();
               try {
                   installer.Install(state);
                   installer.Commit(state);
               } catch {
                   try {
                       installer.Rollback(state);
                   } catch { }
                   throw;
               }
           }
       } catch {
           throw;
       }
   }
   
   private static void UninstallService()
   {
       if ( !IsInstalled() ) return;
       try {
           using ( AssemblyInstaller installer = GetInstaller() ) {
               IDictionary state = new Hashtable();
               try {
                   installer.Uninstall( state );
               } catch {
                   throw;
               }
           }
       } catch {
           throw;
       }
   }
   
   private static void StartService()
   {
       if ( !IsInstalled() ) return;
   
       using (ServiceController controller = 
           new ServiceController("YourServiceName")) {
           try {
               if ( controller.Status != ServiceControllerStatus.Running ) {
                   controller.Start();
                   controller.WaitForStatus( ServiceControllerStatus.Running, 
                       TimeSpan.FromSeconds( 10 ) );
               }
           } catch {
               throw;
           }
       }
   }
   
   private static void StopService()
   {
       if ( !IsInstalled() ) return;
       using ( ServiceController controller = 
           new ServiceController("YourServiceName")) {
           try {
               if ( controller.Status != ServiceControllerStatus.Stopped ) {
                   controller.Stop();
                   controller.WaitForStatus( ServiceControllerStatus.Stopped, 
                        TimeSpan.FromSeconds( 10 ) );
               }
           } catch {
               throw;
           }
       }
   }
   

4. At this point, after you install your service on the target machine, just run your service from the command line (like any ordinary application) with the -install command line argument to install and start your service.

I think I've covered everything, but if you find this doesn't work, please let me know so I can update the answer.

Here is my solution. Use [ExportModelStateToTempData] / [ImportModelStateFromTempData] is uncomfortable in my opinion.

~/Views/Home/Error.cshtml:

@{
    ViewBag.Title = "Error";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Error</h2>
<hr/>

<div style="min-height: 400px;">

    @Html.ValidationMessage("Error")

    <br />
    <br />

    <button onclick="Error_goBack()" class="k-button">Go Back</button>
    <script>
        function Error_goBack() {
            window.history.back()
        }
    </script>

</div>

~/Controllers/HomeController.sc:

public class HomeController : BaseController
{
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Error()
    {
        return this.View();
    }

    ...
}

~/Controllers/BaseController.sc:

public class BaseController : Controller
{
    public BaseController() { }

    protected override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        if (filterContext.Result is ViewResult)
        {
            if (filterContext.Controller.TempData.ContainsKey("Error"))
            {
                var modelState = filterContext.Controller.TempData["Error"] as ModelState;
                filterContext.Controller.ViewData.ModelState.Merge(new ModelStateDictionary() { new KeyValuePair<string, ModelState>("Error", modelState) });
                filterContext.Controller.TempData.Remove("Error");
            }
        }
        if ((filterContext.Result is RedirectResult) || (filterContext.Result is RedirectToRouteResult))
        {
            if (filterContext.Controller.ViewData.ModelState.ContainsKey("Error"))
            {
                filterContext.Controller.TempData["Error"] = filterContext.Controller.ViewData.ModelState["Error"];
            }
        }

        base.OnActionExecuted(filterContext);
    }
}

~/Controllers/MyController.sc:

public class MyController : BaseController
{
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Details(int id)
    {
        if (id != 5)
        {
            ModelState.AddModelError("Error", "Specified row does not exist.");
            return RedirectToAction("Error", "Home");
        }
        else
        {
            return View("Specified row exists.");
        }
    }
}

I wish you successful projects ;-)

Storm's answer is not correct. No hard feelings Storm, and apologies to the OP as I'm a bit late to the party here (wish I could have helped sooner, but I didn't run into the problem until today, or this stack overflow answer until I was figuring out a solution.)

The Visual C++ 2003 runtime was not available as a seperate download because it was included with the .NET 1.1 runtime.

If you install the .NET 1.1 runtime you will get msvcr71.dll installed, and in addition added to C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322.

The .NET 1.1 runtime is available here: http://www.microsoft.com/downloads/en/details.aspx?familyid=262d25e3-f589-4842-8157-034d1e7cf3a3&displaylang=en (23.1 MB)

If you are looking for a file that ends with a "P" such as msvcp71.dll, this indicates that your file was compiled against a C++ runtime (as opposed to a C runtime), in some situations I noticed these files were only installed when I installed the full SDK. If you need one of these files, you may need to install the full .NET 1.1 SDK as well, which is available here: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=9b3a2ca6-3647-4070-9f41-a333c6b9181d (106.2 MB)

After installing the SDK I now have both msvcr71.dll and msvcp71.dll in my System32 folder, and the application I'm trying to run (boomerang c++ decompiler) works fine without any missing DLL errors.

Also on a side note: be VERY aware of the difference between a Hotfix Update and a Regular Update. As noted in the linked KB932298 download (linked below by Storm): "Please be aware this Hotfix has not gone through full Microsoft product regression testing nor has it been tested in combination with other Hotfixes."

Hotfixes are NOT meant for general users, but rather users who are facing a very specific problem. As described in the article only install that Hotfix if you are have having specific daylight savings time issues with the rules that changed in 2007. -- Likely this was a pre-release for customers who "just couldn't wait" for the official update (probably for some business critical application) -- for regular users Windows Update should be all you need.

Thanks, and I hope this helps others who run into this issue!

at new chrome version (maybe 67.0.3396.62) , CSS hex color can use this model display,

eg:

div{
  background-color:#FF00FFcc;
}

cc is opacity , but old chrome not support that mod

Try this:

 str = String.valueOf(a)+String.valueOf(b)+String.valueOf(c);

Output:

ice

Since .Net >= 5.0 the best way is to use Any:

if(!array.Any()) {
   //now you sure it's empty
}

For nullable arrays:

if(!(array?.Any() == true)) {
   //now you sure it's null or empty
}

I'll share my very simple code for sample purpose. Hope it will help someone like me searching for quick code reference. My goal was to receive rsa signature from backend, then validate against input string using public key and store locally for future periodic verifications. Here is main part used for signature verification:

        ...
        var signature = Get(url); // base64_encoded signature received from server
        var inputtext= "inputtext"; // this is main text signature was created for
        bool result = VerifySignature(inputtext, signature);
        ...

    private bool VerifySignature(string input, string signature)
    {
        var result = false;
        using (var cps=new RSACryptoServiceProvider())
        {
            // converting input and signature to Bytes Arrays to pass to VerifyData rsa method to verify inputtext was signed using privatekey corresponding to public key we have below
            byte[] inputtextBytes = Encoding.UTF8.GetBytes(input);
            byte[] signatureBytes  = Convert.FromBase64String(signature);

            cps.FromXmlString("<RSAKeyValue><Modulus>....</Modulus><Exponent>....</Exponent></RSAKeyValue>"); // xml formatted publickey
            result = cps.VerifyData(inputtextBytes , new SHA1CryptoServiceProvider(), signatureBytes  );
        }

        return result;
    }

I wanted to add to the discussion above but don't have the reputation to comment.

Python 3.8 is not quite released yet, but it will even include the reversed() function on dictionaries (removing another difference from OrderedDict.

Dict and dictviews are now iterable in reversed insertion order using reversed(). (Contributed by Rémi Lapeyre in bpo-33462.) See what's new in python 3.8

I don't see any mention of the equality operator or other features of OrderedDict so they are still not entirely the same.

In my case,I was using SubQuery and had a same problem. I realized that the problem is from memory leakage.

Restarting MSSQL service cause to flush tempDb resource and free huge amount of memory. so this was solve the problem.

In rare cases, it can be useful to change the line that is given by __LINE__ to something else. I've seen GNU configure does that for some tests to report appropriate line numbers after it inserted some voodoo between lines that do not appear in original source files. For example:

#line 100

Will make the following lines start with __LINE__ 100. You can optionally add a new file-name

#line 100 "file.c"

It's only rarely useful. But if it is needed, there are no alternatives I know of. Actually, instead of the line, a macro can be used too which must result in any of the above two forms. Using the boost preprocessor library, you can increment the current line by 50:

#line BOOST_PP_ADD(__LINE__, 50)

I thought it's useful to mention it since you asked about the usage of __LINE__ and __FILE__. One never gets enough surprises out of C++ :)

Edit: @Jonathan Leffler provides some more good use-cases in the comments:

Messing with #line is very useful for pre-processors that want to keep errors reported in the user's C code in line with the user's source file. Yacc, Lex, and (more at home to me) ESQL/C preprocessors do that.

The command (or the URL in it) to add the github repository as a remote isn't quite correct. If I understand your repository name correctly, it should be;

git remote add demo_app '[email protected]:levelone/demo_app.git'

Add the following code to wp-config

define('FS_METHOD', 'direct');

FS_METHOD forces the filesystem method. It should only be direct, ssh2, ftpext, or ftpsockets. Generally, you should only change this if you are experiencing update problems. If you change it and it doesn't help, change it back/remove it. Under most circumstances, setting it to 'ftpsockets' will work if the automatically chosen method does not.

(Primary Preference) "direct" forces it to use Direct File I/O requests from within PHP, this is fraught with opening up security issues on poorly configured hosts, This is chosen automatically when appropriate.

(Secondary Preference) "ssh2" is to force the usage of the SSH PHP Extension if installed

(3rd Preference) "ftpext" is to force the usage of the FTP PHP Extension for FTP Access, and finally

(4th Preference) "ftpsockets" utilises the PHP Sockets Class for FTP Access

If once solved a similar issue by simply checking out a new working copy and replacing the .svn directory throwing the commit errors with this newly checked out one. The reason in my case was that after a repository corruption and restore from a backup the working copy was pointing towards a revision that didn't exist in the restored repository. Also got "item out of date" errors. Updating the working copy before commit didn't solve this but replacing the .svn as described above did.

Yes.

In essence, as long as nothing is output, you can do whatever you want (kill a session, remove user cookies, calculate Pi to 'n' digits, etc.) prior to issuing a location header.

I was facing exact same error

Computed property "callRingtatus" was assigned to but it has no setter

here is a sample code according to my scenario

computed: {

callRingtatus(){
            return this.$store.getters['chat/callState']===2
      }

}

I change the above code into the following way

computed: {

callRingtatus(){
       return this.$store.state.chat.callState===2
    }
}

fetch values from vuex store state instead of getters inside the computed hook

Steps to manually configure DNS:

1. You can access Network and Sharing center by right clicking on the Network icon on the taskbar.

2. Now choose adapter settings from the side menu.

3. This will give you a list of the available network adapters in the system . From them right click on the adapter you are using to connect to the internet now and choose properties option.

4. In the networking tab choose ‘Internet Protocol Version 4 (TCP/IPv4)’.

5. Now you can see the properties dialogue box showing the properties of IPV4. Here you need to change some properties.

   Select ‘use the following DNS address’ option. Now fill the following fields as given here.

   Preferred DNS server: 208.67.222.222

   Alternate DNS server : 208.67.220.220

   This is an available Open DNS address. You may also use google DNS server addresses.

   After filling these fields. Check the ‘validate settings upon exit’ option. Now click OK.

You have to add this DNS server address in the router configuration also (by referring the router manual for more information).

Refer : for above method & alternative

If none of this works, then open command prompt(Run as Administrator) and run these:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log
Exit

Hopefully that fixes it, if its still not fixed there is a chance that its a NIC related issue(driver update or h/w).

Also FYI, this has a thread on Microsoft community : Windows 10 - DNS Issue
