you can use it.

  toolbar.setTitleTextColor(getResources().getColor(R.color.white));

There seem to be a lot of solutions for Windows here but this is the simplest:

Tools -> Build System -> New Build System, type in the above, save as Browser.sublime-build:

{
    "cmd": "explorer $file"
}

Then go back to your HTML file. Tools -> Build System -> Browser. Then press CTRL-B and the file will be opened in whatever browser is your system default browser.

Using nextline and System.in.read as often proposed requires the user to hit enter after typing a character. However, people searching for an answer to this question, may also be interested in directly respond to a key press in a console!

I found a solution to do so using jline3, wherein we first change the terminal into rawmode to directly respond to keys, and then wait for the next entered character:

var terminal = TerminalBuilder.terminal()
terminal.enterRawMode()
var reader = terminal.reader()

var c = reader.read()

<dependency>
    <groupId>org.jline</groupId>
    <artifactId>jline</artifactId>
    <version>3.12.3</version>
</dependency>

If you want a formula to do it then:

=IF(ISNUMBER(SEARCH("*texts are *",A1)),LEFT(A1,FIND("texts are ",A1) + 9) & "WORD",A1)

This will do it. Change `"WORD" To the word you want.

_([1,2,3]).find(function(v){
    return v if (v==2);
})

Assuming the value is nvarchar type for that only we are using N''

If the formulas are identical you can use Find and Replace with Match entire cell contents checked and Look in: Formulas. Select the range, go into Find and Replace, make your entries and `Replace All.

Or do you mean that there are several formulas with this same form, but different cell references? If so, then one way to go is a regular expression match and replace. Regular expressions are not built into Excel (or VBA), but can be accessed via Microsoft's VBScript Regular Expressions library.

The following function provides the necessary match and replace capability. It can be used in a subroutine that would identify cells with formulas in the specified range and use the formulas as inputs to the function. For formulas strings that match the pattern you are looking for, the function will produce the replacement formula, which could then be written back to the worksheet.

Function RegexFormulaReplace(formula As String)
    Dim regex As New RegExp
    regex.Pattern = "=\(\(([A-Z]+\d+)-([A-Z]+\d+)\)/([A-Z]+\d+)\)"
'   Test if a match is found
    If regex.Test(formula) = True Then
        RegexFormulaReplace = regex.Replace(formula, "=(EXP((LN($1/$2)/14.32))-1")
    Else
        RegexFormulaReplace = CVErr(xlErrValue)
    End If
    Set regex = Nothing
End Function

In order for the function to work, you would need to add a reference to the Microsoft VBScript Regular Expressions 5.5 library. From the Developer tab of the main ribbon, select VBA and then References from the main toolbar. Scroll down to find the reference to the library and check the box next to it.

If you don't care about the security of your SSH keys, there are many good answers here. If you do, the best answer I found was from a link in a comment above to this GitHub comment by diegocsandrim. So that others are more likely to see it, and just in case that repo ever goes away, here is an edited version of that answer:

Most solutions here end up leaving the private key in the image. This is bad, as anyone with access to the image has access to your private key. Since we don't know enough about the behavior of squash, this may still be the case even if you delete the key and squash that layer.

We generate a pre-sign URL to access the key with aws s3 cli, and limit the access for about 5 minutes, we save this pre-sign URL into a file in repo directory, then in dockerfile we add it to the image.

In dockerfile we have a RUN command that do all these steps: use the pre-sing URL to get the ssh key, run npm install, and remove the ssh key.

By doing this in one single command the ssh key would not be stored in any layer, but the pre-sign URL will be stored, and this is not a problem because the URL will not be valid after 5 minutes.

The build script looks like:

# build.sh
aws s3 presign s3://my_bucket/my_key --expires-in 300 > ./pre_sign_url
docker build -t my-service .

Dockerfile looks like this:

FROM node

COPY . .

RUN eval "$(ssh-agent -s)" && \
    wget -i ./pre_sign_url -q -O - > ./my_key && \
    chmod 700 ./my_key && \
    ssh-add ./my_key && \
    ssh -o StrictHostKeyChecking=no [email protected] || true && \
    npm install --production && \
    rm ./my_key && \
    rm -rf ~/.ssh/*

ENTRYPOINT ["npm", "run"]

CMD ["start"]

Using moment will be much easier in this case, You could try this:

    let days = moment(yourFirstDateString).diff(moment(yourSecondDateString), 'days');

It will give you integer value like 1,2,5,0etc so you can easily use condition check like:

if(days < 1) {

Also, one more thing is you can get more accurate result of the time difference (in decimals like 1.2,1.5,0.7etc) to get this kind of result use this syntax:

let days = moment(yourFirstDateString).diff(moment(yourSecondDateString), 'days', true);

Let me know if you have any further query

all:
    echo ${PATH}

Or change PATH just for one command:

all:
    PATH=/my/path:${PATH} cmd

This question actually is not JSP related, it is HTTP related. you can just do:

window.location = window.location;

You could use diff with following output formatting:

diff --old-line-format='' --unchanged-line-format='' file1 file2

--old-line-format='' , disable output for file1 if line was differ compare in file2.
--unchanged-line-format='', disable output if lines were same.

This is very simple if you are not using SQLite:

You can delete the SQLite DLLs from your solution's bin folders, then from the folder where you reference ELMAH. Rebuild, and your app won't try to load this DLL that you are not using.

^[ _]*[A-Z0-9][A-Z0-9 _]*$

You can optionally have some spaces or underscores up front, then you need one letter or number, and then an arbitrary number of numbers, letters, spaces or underscores after that.

Something that contains only spaces and underscores will fail the [A-Z0-9] portion.

Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity).

Make sure you refer to the property as fileName in the Criteria query, not filename.

Specifically, Hibernate will call the getter method of the filename property when executing that Criteria query, so it will look for a method called getFilename(). But the property is called FileName and the getter getFileName().

So, change the projection like so:

criteria.setProjection(Projections.property("fileName"));

SELECT * 
FROM table 
WHERE id = (SELECT MAX(id) FROM TABLE)

I just create a "help" version of the function. Shows up right below the function in autocomplete - the user can select it instead in an adjacent cell for instructions.

Public Function Foo(param1 as range, param2 as string) As String

    Foo = "Hello world"

End Function

Public Function Foo_Help() as String

Foo_Help = "The Foo function was designed to return the Foo value for a specified range a cells given a specified constant." & CHR(10) & "Parameters:" & CHR(10)
& "  param1 as Range   :   Specifies the range of cells the Foo function should operate on." & CHR(10)
&"  param2 as String  :   Specifies the constant the function should use to calculate Foo"
&" contact the Foo master at [email protected] for more information."

END FUNCTION

The carriage returns improve readability with wordwrap on. 2 birds with one stone, now the function has some documentation.

Just found an article from Anand Mani Sankar wich shows a simple way of using nginx upstream proxy with docker composer.

Basically one must configure the instance linking and ports at the docker-compose file and update upstream at nginx.conf accordingly.

Maybe you want unpack elements of array, I don't know if I got it, but below a example:

def my_func(*args):
    for a in args:
        print a

my_func(*[1,2,3,4])
my_list = ['a','b','c']
my_func(*my_list)

The standard MIME type for ZIP files is application/zip. The types for the files inside the ZIP does not matter for the MIME type.

As always, it ultimately depends on your server setup.

It's possible to "natively" select by value:

Cache.delete() can also be used for new chrome, firefox and opera.

Let's get you started. Do you have any knowledge in Oracle?

First you need to understand what a SCHEMA is. A schema is a collection of logical structures of data, or schema objects. A schema is owned by a database user and has the same name as that user. Each user owns a single schema. Schema objects can be created and manipulated with SQL.

1. CREATE USER acoder; -- whenever you create a new user in Oracle, a schema with the same name as the username is created where all his objects are stored.
2. GRANT CREATE SESSION TO acoder; -- Failure to do this you cannot do anything.

To access another user's schema, you need to be granted privileges on specific object on that schema or optionally have SYSDBA role assigned.

That should get you started.

Android Studio (version: 1.3.2) allows you to seamlessly access the .jar inside a .aar.

Bonus: it automatically decompiles the classes!

Simply follow these steps:

1. File > New > New Module > Import .JAR/.AAR Package to import you .aar as a module

2. Add the newly created module as a dependency to your main project (not sure if needed)

3. Right click on "classes.jar" as shown in the capture below, and click "Show in explorer". Here is your .jar.

You can also try pressing the "FN" or function key with the button "Break" or with the button "sys rq" - system request as this - must be pressed together and this stops any running macro

At the place of uniqueIntNo put unique integer number like this:

mNotificationManager.notify(uniqueIntNo, builder.build());

here you go get_the_category( $post->ID ); will return the array of categories of that post you need to loop through the array

$category_detail=get_the_category('4');//$post->ID
foreach($category_detail as $cd){
echo $cd->cat_name;
}

get_the_category

I know this post is old, but I had a Situation like this and just want to share my solution. All the answers above work fine. But if you have a Code such as those in data.table chaining Syntax it becomes abit challenging. e.g. I had a Problem like this.

mass <- files[, Veg:=tstrsplit(files$file, "/")[1:4][[1]]][, Rain:=tstrsplit(files$file, "/")[1:4][[2]]][, Roughness:=tstrsplit(files$file, "/")[1:4][[3]]][, Geom:=tstrsplit(files$file, "/")[1:4][[4]]][time_[s]<=12000]

I tried most of the suggestions above and they didn´t work. but I figured out that they can be split after the comma within []. Splitting at ][ doesn´t work.

mass <- files[, Veg:=tstrsplit(files$file, "/")[1:4][[1]]][, 
    Rain:=tstrsplit(files$file, "/")[1:4][[2]]][, 
    Roughness:=tstrsplit(files$file, "/")[1:4][[3]]][, 
    Geom:=tstrsplit(files$file, "/")[1:4][[4]]][`time_[s]`<=12000]

Managed Code

Managed code is what Visual Basic .NET and C# compilers create. It runs on the CLR (Common Language Runtime), which, among other things, offers services like garbage collection, run-time type checking, and reference checking. So, think of it as, "My code is managed by the CLR."

Visual Basic and C# can only produce managed code, so, if you're writing an application in one of those languages you are writing an application managed by the CLR. If you are writing an application in Visual C++ .NET you can produce managed code if you like, but it's optional.

Unmanaged Code

Unmanaged code compiles straight to machine code. So, by that definition all code compiled by traditional C/C++ compilers is 'unmanaged code'. Also, since it compiles to machine code and not an intermediate language it is non-portable.

No free memory management or anything else the CLR provides.

Since you cannot create unmanaged code with Visual Basic or C#, in Visual Studio all unmanaged code is written in C/C++.

Mixing the two

Since Visual C++ can be compiled to either managed or unmanaged code it is possible to mix the two in the same application. This blurs the line between the two and complicates the definition, but it's worth mentioning just so you know that you can still have memory leaks if, for example, you're using a third party library with some badly written unmanaged code.

Here's an example I found by googling:

#using <mscorlib.dll>
using namespace System;

#include "stdio.h"

void ManagedFunction()
{
    printf("Hello, I'm managed in this section\n");
}

#pragma unmanaged
UnmanagedFunction()
{
    printf("Hello, I am unmanaged through the wonder of IJW!\n");
    ManagedFunction();
}

#pragma managed
int main()
{
    UnmanagedFunction();
    return 0;
}

As of 2019 there is a subcommand: vagrant box repackage

vagrant box repackage --help 
Usage: vagrant box repackage <name> <provider> <version>
    -h, --help                       Print this help

You can find name provider and version by running vagrant box list

vagrant box list
macinbox (virtualbox, 10.14.5)

The ouput of vagrant box repackage is a file called package.box which is basically a tgz file which the content can be listed as below:

tar tzf package.box
./metadata.json
./box.ovf
./Vagrantfile
./box-disk001.vmdk

If the child is always going to be a specific tag then you could do it like this

function test(el)
{
 var children = el.getElementsByTagName('div');// any tag could be used here..

  for(var i = 0; i< children.length;i++)
  {
    if (children[i].getAttribute('id') == 'child') // any attribute could be used here
    {
     // do what ever you want with the element..  
     // children[i] holds the element at the moment..

    }
  }
}

Your code is indeed using the normal way to create and delete a dynamic object. Yes, it's perfectly normal (and indeed guaranteed by the language standard!) that delete will call the object's destructor, just like new has to invoke the constructor.

If you weren't instantiating Object1 directly but some subclass thereof, I'd remind you that any class intended to be inherited from must have a virtual destructor (so that the correct subclass's destructor can be invoked in cases analogous to this one) -- but if your sample code is indeed representative of your actual code, this cannot be your current problem -- must be something else, maybe in the destructor code you're not showing us, or some heap-corruption in the code you're not showing within that function or the ones it calls...?

BTW, if you're always going to delete the object just before you exit the function which instantiates it, there's no point in making that object dynamic -- just declare it as a local (storage class auto, as is the default) variable of said function!

yes is possible to run your android emulator without have a hardware accelerator. In fact to do that, you need to open your android virtual device. When you reached to system image configure, it suggest you which version of android image you want to use. Whatever version of android system image that you select,you need to make sure that,ABI is armeabi-v7a and, you target is System image ameabi-v7a with google APIs. And then complete the rest of task and check out your emulator.

You would have to tune it according to your environment.

Sometimes it's more useful to increase the size of the backlog (acceptCount) instead of the maximum number of threads.

Say, instead of

<Connector ... maxThreads="500" acceptCount="50"

you use

<Connector ... maxThreads="300" acceptCount="150"

you can get much better performance in some cases, cause there would be less threads disputing the resources and the backlog queue would be consumed faster.

In any case, though, you have to do some benchmarks to really know what is best.

I don't know why this question was reopened but here is a tidyverse option.

x %>% 
  arrange(desc(value)) %>%
  mutate(variable=fct_reorder(variable,value)) %>% 
ggplot(aes(variable,value,fill=variable)) + geom_bar(stat="identity") + 
  scale_y_continuous("",label=scales::percent) + coord_flip() 

This is the best and easiest code:

public class test
{
    public static void main(String str[])
    {
        String jsonString = "{\"stat\": { \"sdr\": \"aa:bb:cc:dd:ee:ff\", \"rcv\": \"aa:bb:cc:dd:ee:ff\", \"time\": \"UTC in millis\", \"type\": 1, \"subt\": 1, \"argv\": [{\"type\": 1, \"val\":\"stackoverflow\"}]}}";
        JSONObject jsonObject = new JSONObject(jsonString);
        JSONObject newJSON = jsonObject.getJSONObject("stat");
        System.out.println(newJSON.toString());
        jsonObject = new JSONObject(newJSON.toString());
        System.out.println(jsonObject.getString("rcv"));
       System.out.println(jsonObject.getJSONArray("argv"));
    }
}

The library definition of the json files are given here. And it is not same libraries as posted here, i.e. posted by you. What you had posted was simple json library I have used this library.

You can download the zip. And then create a package in your project with org.json as name. and paste all the downloaded codes there, and have fun.

I feel this to be the best and the most easiest JSON Decoding.

for element in somelist:
    do_action(element)
somelist[:] = (x for x in somelist if not check(x))

If you really need to do it in one pass without copying the list

i=0
while i < len(somelist):
    element = somelist[i] 
    do_action(element)
    if check(element):
        del somelist[i]
    else:
        i+=1

It's probably easier to create your keys under linux and use PuTTYgen to convert the keys to PuTTY format.

PuTTY Faq: A.2.2

In a broad sense, Socket - is just that, a socket, just like your electrical, cable or telephone socket. A point where "requisite stuff" (power, signal, information) can go out and come in from. It hides a lot of detailed stuff, which is not required for the use of the "requisite stuff". In software parlance, it provides a generic way of defining a mechanism of communication between two entities (those entities could be anything - two applications, two physically separate devices, User & Kernel space within an OS, etc)

A Port is an endpoint discriminator. It differentiates one endpoint from another. At networking level, it differentiates one application from another, so that the networking stack can pass on information to the appropriate application.

You can write yourself a little console app and use System.Environment.Version to find out the version. Scott Hanselman gives a blog post about it.

Or look in the registry for the installed versions. HKLM\Software\Microsoft\NETFramework Setup\NDP

To view the content in alert use:

alert( $(response).find("#result").html() );

sort() was deprecated for DataFrames in favor of either:

• sort_values() to sort by column(s)
• sort_index() to sort by the index

sort() was deprecated (but still available) in Pandas with release 0.17 (2015-10-09) with the introduction of sort_values() and sort_index(). It was removed from Pandas with release 0.20 (2017-05-05).

You haven't specified what kind of html element you are trying to do an absolute xpath search on. In your case, it's the input element.

Try this:

element = findElement(By.xpath("//input[@class='t-TextBox' and @type='email' and @test-    
id='test-username']");

Using GNU sed:

sed "/cdef/aline1\nline2\nline3\nline4" input.txt

If you started with:

abcd
accd
cdef
line
web

this would produce:

abcd
accd
cdef
line1
line2
line3
line4
line
web

If you want to save the changes to the file in-place, say:

sed -i "/cdef/aline1\nline2\nline3\nline4" input.txt

You forgot the .class:

if (value.getClass() == Integer.class) {
    System.out.println("This is an Integer");
} 
else if (value.getClass() == String.class) {
    System.out.println("This is a String");
}
else if (value.getClass() == Float.class) {
    System.out.println("This is a Float");
}

Note that this kind of code is usually the sign of a poor OO design.

Also note that comparing the class of an object with a class and using instanceof is not the same thing. For example:

"foo".getClass() == Object.class

is false, whereas

"foo" instanceof Object

is true.

Whether one or the other must be used depends on your requirements.

As you know JBoss is a purely filesystem based installation. To install you simply unzip a file and thats it. Once you install a certain folder structure is created by default and as you run the JBoss instance for the first time, it creates additional folders for runtime operation. For comparison here is the structure of JBoss AS 7 before and after you start for the first time

Before

jboss-as-7
 |
 |---> standalone
 |      |----> lib
 |      |----> configuration
 |      |----> deployments
 |      
 |---> domain
 |....

After

jboss-as-7
     |
     |---> standalone
     |      |----> lib
     |      |----> configuration
     |      |----> deployments
     |      |----> tmp
     |      |----> data
     |      |----> log
     |      
     |---> domain
     |....

As you can see 3 new folders are created (log, data & tmp). These folders can all be deleted without effecting the application deployed in deployments folder unless your application generated Data that's stored in those folders. In development, its ok to delete all these 3 new folders assuming you don't have any need for the logs and data stored in "data" directory.

For production, ITS NOT RECOMMENDED to delete these folders as there maybe application generated data that stores certain state of the application. For ex, in the data folder, the appserver can save critical Tx rollback logs. So contact your JBoss Administrator if you need to delete those folders for any reason in production.

Good luck!

also try include_once() instead of include() that can also work

Check that your remote host (i.e. the web hosting server you're trying to connect FROM) allows OUTGOING traffic on port 3306.

I saw the (100) error in this situation. I could connect from my PC/Mac, but not from my website. The MySQL instance was accessible via the internet, but my hosting company wasn't allowing my website to connect to the database on port 3306.

Once I asked my hosting company to open my web hosting account up to outgoing traffic on port 3306, my website could connect to my remote database.

There is no config file unless you create one yourself. However, the port is a parameter of the listen() function. For example, to listen on port 8124:

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(8124, "127.0.0.1");
console.log('Server running at http://127.0.0.1:8124/');

If you're having problems finding a port that's open, you can go to the command line and type:

netstat -ano

To see a list of all ports in use per adapter.

You need a delimiter for your pattern. It should be added at the start and end of the pattern like so:

$pattern = "/My name is '(.*)' and im fine/";  // With / as a delimeter 

To do this, I had to come up with an intermediate data structure:

class KeyDataPoint {
    String key;
    DateTime timestamp;
    Number data;
    // obvious constructor and getters
}

With this in place, the approach is to "flatten" each MultiDataPoint into a list of (timestamp, key, data) triples and stream together all such triples from the list of MultiDataPoint.

Then, we apply a groupingBy operation on the string key in order to gather the data for each key together. Note that a simple groupingBy would result in a map from each string key to a list of the corresponding KeyDataPoint triples. We don't want the triples; we want DataPoint instances, which are (timestamp, data) pairs. To do this we apply a "downstream" collector of the groupingBy which is a mapping operation that constructs a new DataPoint by getting the right values from the KeyDataPoint triple. The downstream collector of the mapping operation is simply toList which collects the DataPoint objects of the same group into a list.

Now we have a Map<String, List<DataPoint>> and we want to convert it to a collection of DataSet objects. We simply stream out the map entries and construct DataSet objects, collect them into a list, and return it.

The code ends up looking like this:

Collection<DataSet> convertMultiDataPointToDataSet(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.getData().entrySet().stream()
                           .map(e -> new KeyDataPoint(e.getKey(), mdp.getTimestamp(), e.getValue())))
        .collect(groupingBy(KeyDataPoint::getKey,
                    mapping(kdp -> new DataPoint(kdp.getTimestamp(), kdp.getData()), toList())))
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

I took some liberties with constructors and getters, but I think they should be obvious.

Somebody posted this code, which has the problem of not retaining the scroll position when restored. The reason is that people tend to apply it to html and body or just the body but it should be applied to html only. This way when restored the scroll position will be kept:

$('html').css({
    'overflow': 'hidden',
    'height': '100%'
});

To restore:

$('html').css({
    'overflow': 'auto',
    'height': 'auto'
});

Just saw that question on one of the interview question, if possible to change final variable with reflection or in runtime. Got really interested, so that what I became with:

 /**
 * @author Dmitrijs Lobanovskis
 * @since 03/03/2016.
 */
public class SomeClass {

    private final String str;

    SomeClass(){
        this.str = "This is the string that never changes!";
    }

    public String getStr() {
        return str;
    }

    @Override
    public String toString() {
        return "Class name: " + getClass() + " Value: " + getStr();
    }
}

Some simple class with final String variable. So in the main class import java.lang.reflect.Field;

/**
 * @author Dmitrijs Lobanovskis
 * @since 03/03/2016.
 */
public class Main {


    public static void main(String[] args) throws Exception{

        SomeClass someClass = new SomeClass();
        System.out.println(someClass);

        Field field = someClass.getClass().getDeclaredField("str");
        field.setAccessible(true);

        field.set(someClass, "There you are");

        System.out.println(someClass);
    }
}

_{I guess many people are entering in this question looking for a way to avoid the new line in awk. Thus, I am going to offer a solution to just that, since the answer to the specific context was already solved!}

In awk, print automatically inserts a ORS after printing. ORS stands for "output record separator" and defaults to the new line. So whenever you say print "hi" awk prints "hi" + new line.

This can be changed in two different ways: using an empty ORS or using printf.

Using an empty ORS

awk -v ORS= '1' <<< "hello
man"

This returns "helloman", all together.

The problem here is that not all awks accept setting an empty ORS, so you probably have to set another record separator.

awk -v ORS="-" '{print ...}' file

For example:

awk -v ORS="-" '1' <<< "hello
man"

Returns "hello-man-".

Using printf (preferable)

While print attaches ORS after the record, printf does not. Thus, printf "hello" just prints "hello", nothing else.

$ awk 'BEGIN{print "hello"; print "bye"}'
hello
bye
$ awk 'BEGIN{printf "hello"; printf "bye"}'
hellobye

Finally, note that in general this misses a final new line, so that the shell prompt will be in the same line as the last line of the output. To clean this, use END {print ""} so a new line will be printed after all the processing.

$ seq 5 | awk '{printf "%s", $0}'
12345$
#    ^ prompt here

$ seq 5 | awk '{printf "%s", $0} END {print ""}'
12345

Just as an FYI, here is my working code:

src_dir = "C:\\temp\\CSV\\"
target_dir = "C:\\temp\\output2\\"
keyword = "KEYWORD"

for f in os.listdir(src_dir):
    file_name = os.path.join(src_dir, f)
    out_file = os.path.join(target_dir, f)
    with open(file_name, "r+") as fi, open(out_file, "w") as fo:
        for line in fi:
            if keyword not in line:
                fo.write(line)

Thanks again to everyone for all the great feedback!

I am late to the game but I found a nice solution. I created a custom attribute directive all you need to do is pass in the gridApi and it will automatically calculate the height. It also subscribes to the pagination change event so if the user changes page size it will resize.

class UIGridAutoResize implements ng.IDirective {
    link: (scope: ng.IScope, element: ng.IAugmentedJQuery, attrs: ng.IAttributes) => void;
    scope: { gridApi: "=" };
    restrict = "A";

    private previousValue: string;
    private isValid: boolean = true;
    private watch: any;

    constructor($timeout: ng.ITimeoutService) {
        UIGridAutoResize.prototype.link = (scope: ng.IScope, element: ng.IAugmentedJQuery, attrs: ng.IAttributes) => {
            const gridOptions = scope.$eval(attrs.uiGrid) as any;
            const gridApi = scope.$eval(attrs.gridResize) as any;

            gridApi.core.on.rowsRendered(scope, () => {
                $timeout(() => {
                    this.autoSizeGrid(element, attrs, gridOptions, gridApi, false);
                }, 100);
            });

            gridApi.core.on.filterChanged(scope, () => {
                this.autoSizeGrid(element, attrs, gridOptions, gridApi, false);
            });

            if (attrs.uiGridPagination === "") {
                gridApi.pagination.on.paginationChanged(null, () => {
                    this.autoSizeGrid(element, attrs, gridOptions, gridApi, true);
                });
            }

            angular.element(window).resize(() => {

Just go to OUTPUT window, then click on Packages icon (it is located between Plot and Help icons). Remove "tick / check mark" from the package you wanted be unload.

For again using the package just put a "tick or Check mark" in front of package or use :

You need to add the "Maven Dependency" in the Deployment Assembly

• right click on your project and choose properties.
• click on Deployment Assembly.
• click add
• click on "Java Build Path Entries"
• select Maven Dependencies"
• click Finish.

Rebuild and deploy again

Note: This is also applicable for non maven project.

Maybe you mean

select x
from some_table
where some_column is null or some_column = ''

but I can't tell since you didn't really ask a question.

By default a span is an inline element... so that's not the default behavior.

You can make the span behave that way by adding display: block; to your CSS.

span {
    display: block;
    width: 100px;
}

I would still recommend Firebug. Not only it can debug JS within your JSP files, it can enhance debugging experience with addons like JS Deminifier (if your production JS is minified), FireQuery, FireRainbow and more.

There is also Firebug lite which is nothing but a bookmarklet. It lets you do limited things but still is useful.

Chrome as a developer console built-in that would let you modify javascript.

Using these tools, you should be able to inject your own JS too.

As far as I know Angular-cli file can't be created via a command like Package-lock file, If you want to create it, you have to do it manually.

1. You can type ng new to create a new angular project

2. Locate its .angular-cli.json file

3. Copy all its content

4. Create a folder in your original project, and name it .angular-cli.json

5. Paste what copied from new project in newly created angular cli file of original project.

6. Locate this line in angular cli file you created, and change the name field to original project's name. You can find the project name in package.json file

project": {
  "name": "<name of the project>"
},

However, in newer angular version now it uses angular.json instead of angular-cli.json.

Simple two formatters we have used:

1. Which format date do we want?
2. Which format date is actually present?

We parse the full date to time format:

date="2016-05-06 16:40:32";

public static String setDateParsing(String date) throws ParseException {

    // This is the format date we want
    DateFormat mSDF = new SimpleDateFormat("hh:mm a");

    // This format date is actually present
    SimpleDateFormat formatter = new SimpleDateFormat("yyyy-mm-dd hh:mm");
    return mSDF.format(formatter.parse(date));
}

In your code, try enclosing password inside single quote. Alternatively, as per the documentation of mysql, following should work -

SET PASSWORD FOR 'jeffrey'@'localhost' = PASSWORD('cleartext password');

FLUSH PRIVILEGES;

The last line is important or else your password change won't take effect unfortunately.

EDIT:

I ran a test in my local and it worked -

mysql>  set password for 'test' = PASSWORD('$w0rdf1sh');
Query OK, 0 rows affected (0.00 sec)

Mine is version 5. You can use following command to determine your version -

SHOW VARIABLES LIKE "%version%";

Try running the command brew doctor and let us know what sort of output you get

edit: And to answer the title question, this is from their FAQ :

Homebrew doesn’t write files outside its prefix. So generally you can just rm -rf the folder you installed it in.

So following that up with a clean re-install (following their latest recommended steps) should be your best bet.

There is an option to disable cross-origin restrictions in Safari 9, different from local file restrictions as mentioned above.

In Firefox, any invalid Date is returned as a Date object as Date 1899-11-29T19:00:00.000Z, therefore check if browser is Firefox then get Date object of string "1899-11-29T19:00:00.000Z".getDate(). Finally compare it with the date.

You can override the __new__ method like this:

class Singleton(object):
    _instance = None
    def __new__(cls, *args, **kwargs):
        if not cls._instance:
            cls._instance = super(Singleton, cls).__new__(
                                cls, *args, **kwargs)
        return cls._instance


if __name__ == '__main__':
    s1 = Singleton()
    s2 = Singleton()
    if (id(s1) == id(s2)):
        print "Same"
    else:
        print "Different"

Simply call list on the generator.

lst = list(gen)
lst

Be aware that this affects the generator which will not return any further items.

You also cannot directly call list in IPython, as it conflicts with a command for listing lines of code.

Tested on this file:

def gen():
    yield 1
    yield 2
    yield 3
    yield 4
    yield 5
import ipdb
ipdb.set_trace()

g1 = gen()

text = "aha" + "bebe"

mylst = range(10, 20)

which when run:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> lst = list(g1)
ipdb> lst
[1, 2, 3, 4, 5]
ipdb> q
Exiting Debugger.

General method for escaping function/variable/debugger name conflicts

There are debugger commands p and pp that will print and prettyprint any expression following them.

So you could use it as follows:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> p list(g1)
[1, 2, 3, 4, 5]
ipdb> c

There is also an exec command, called by prefixing your expression with !, which forces debugger to take your expression as Python one.

ipdb> !list(g1)
[]

For more details see help p, help pp and help exec when in debugger.

ipdb> help exec
(!) statement
Execute the (one-line) statement in the context of
the current stack frame.
The exclamation point can be omitted unless the first word
of the statement resembles a debugger command.
To assign to a global variable you must always prefix the
command with a 'global' command, e.g.:
(Pdb) global list_options; list_options = ['-l']

I guess the dirtiest solution is this:

list(eval('0, 0, 0, 11, 0, 0, 0, 11'))

Because comparison doesn't work that way. 'Y' || 'y' is a logical-or operator; it returns 1 (true) if either of its arguments is true. Since 'Y' and 'y' are both true, you're comparing *answer with 1.

What you want is if(*answer == 'Y' || *answer == 'y') or perhaps:

switch (*answer) {
  case 'Y':
  case 'y':
    /* Code for Y */
    break;
  default:
    /* Code for anything else */
}

IIS sessions timeout value is for classic .asp applications only, this is controlled on IIS configuration. In your case For ASP.NET apps, only the web.config-specified timeout value applies.

It might be a wrong path. Ensure in your main app file you have:

app.use(express.static(path.join(__dirname,"public")));

Example link to your css as:

<link href="/css/clean-blog.min.css" rel="stylesheet">

similar for link to js files:

<script src="/js/clean-blog.min.js"></script>

If you haven't already pushed the commits then you can go back to a previous commit using git reset HEAD^[1,2,3,4...]

For example

git commit <file1> -m "Updated files 1 and 2"
git commit <file3> -m "Updated file 3"

Oops, forgot to add file2 to the first commit...

git reset HEAD^1 // because I only need to go back 1 commit

git add <file2>

This will add file2 to the first commit.

If you want 8 bit representation of characters that used in many encoding, this may help you.

You must change variable targetEncoding to whatever encoding you want.

Encoding targetEncoding = Encoding.GetEncoding(874); // Your target encoding
Encoding utf8 = Encoding.UTF8;

var stringBytes = utf8.GetBytes(Name);
var stringTargetBytes = Encoding.Convert(utf8, targetEncoding, stringBytes);
var ascii8BitRepresentAsCsString = Encoding.GetEncoding("Latin1").GetString(stringTargetBytes);

Looking at the Toolbar and TintManager source, drawable/abc_ic_ab_back_mtrl_am_alpha is tinted with the value of the style attribute colorControlNormal.

I did try setting this in my project (with <item name="colorControlNormal">@color/my_awesome_color</item> in my theme), but it's still black for me.

Update:

Found it. You need to set the actionBarTheme attribute (not actionBarStyle) with colorControlNormal.

Eg:

<style name="MyTheme" parent="Theme.AppCompat.Light">        
    <item name="actionBarTheme">@style/MyApp.ActionBarTheme</item>
    <item name="actionBarStyle">@style/MyApp.ActionBar</item>
    <!-- color for widget theming, eg EditText. Doesn't effect ActionBar. -->
    <item name="colorControlNormal">@color/my_awesome_color</item>
    <!-- The animated arrow style -->
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

<style name="MyApp.ActionBarTheme" parent="@style/ThemeOverlay.AppCompat.ActionBar">       
    <!-- THIS is where you can color the arrow! -->
    <item name="colorControlNormal">@color/my_awesome_color</item>
</style>

<style name="MyApp.ActionBarStyle" parent="@style/Widget.AppCompat.Light.ActionBar">
    <item name="elevation">0dp</item>      
    <!-- style for actionBar title -->  
    <item name="titleTextStyle">@style/ActionBarTitleText</item>
    <!-- style for actionBar subtitle -->  
    <item name="subtitleTextStyle">@style/ActionBarSubtitleText</item>

    <!-- 
    the actionBarTheme doesn't use the colorControlNormal attribute
    <item name="colorControlNormal">@color/my_awesome_color</item>
     -->
</style>

I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer

Clear file input with JavaScript

document.getElementById("fileInputId").value = null;

I know this is way old, but I have a really cool way of doing this that is worth sharing.

What is required in Conemu and WinSCP. These are simple instructions

1. Open WinSCP.exe and login to my desired remote server (I have
   found that it's important to login before attaching ... ).

2. In the preferences for WinSCP - two settings to change. Choose Explorer type interface and rather than Commander - so you don't see local files. Unless you want to (but that seems like it would suck here). Set up Sublime as your default editor.

3. With ConEmu open, right click the tab bar and select the option Attach to.... A dialog box will open with your running applications. Choose, WinSCP and select OK. ConEmu will now have an open tab with WinSCP displaying your remote files.

4. Right click on the WinSCP tab and choose New console.... When the dialog box opens, enter the path to the Sublime executable on your system. Before you press Start, In the box that says New console split select the radio button to right and set the percentage. I usually choose 75%, but you can customize this to your liking, and it can be changed later.

   5. Now you will see Sublime in the same window running to the right of WinSCP. In Sublime, from the View menu, choose Sidebar->Hide Sidebar, and bam, you now have remote files in exactly the same manner as you would locally - with a few caveats of course that comes with editing anything remotely. WinSCP is lightening fast though.

I have two monitors - left monitor display's Chrome browser, right monitor displays code editor. Also in ConEmu, I create another tab and ssh into the site I'm working on, so I can do things like run gulp or grunt remotely and also manipulate files from the command line. Seriously sped up development.

Here's a screenshot:

In Xcode > 4.3:

You click on the scheme drop down bar -> edit scheme -> arguments tab and then add NSZombieEnabled in the Environment Variables column and YES in the value column.

Good Luck !!!

You can do this:

.thing {
  border: 2px solid transparent;
}
.thing:hover {
  border: 2px solid green;
}

You can use MD5() in mysql or md5() in php. To use salt add it to password before running md5, f.e.:

$salt ='my_string';
$hash = md5($salt . $password);

It's better to use different salt for every password. For this you have to save your salt in db (and also hash). While authentication user will send his login and pass. You will find his hash and salt in db and find out:

if ($hash == md5($salt . $_POST['password'])) {}

The code below works. Replace the text within the single quotes with your image name. If it is in the same folder, if not add ../foldername/'yourimagename' I hope that helps.

NOTE:

use of the single quotes by most of the programmers is not advised but I use it and it works. Also, if you would write a PHP you would appreciate what it can do i.e. add the background image automatically from the variable etc.

<html>
<head>
<style type="text/css">
.btn-pTool{
margin:0;
padding:0;
background-image: url('your name of the field');
height:100px;
width:200px;
display:block;
}

.btn-pToolName{
    text-align: center; 
    width: 26px; 
    height: 190px; 
    display: block; 
    color: #fff; 
    text-decoration: none;  
    font-family: Arial, Helvetica, sans-serif;  
    font-weight: bold; 
    font-size: 1em; 
    line-height: 32px; 
    }
    </style>
    </head>
    <body>
    <div class="pToolContainer">
    <span class="btn-pTool"><a class="btn-pToolName" href="#">Test text</a></span>
    <div class="pToolSlidePanel">Test text</div>
    </div>
    </body>
    </html>

Let me help you understand it with an example of "codaddict's algorithm"

'Dictionary in C#' is 'Hashmap in Java' in parallel universe.

Some implementations are different. See the example below to understand better.

Declaring Java HashMap:

Map<Integer, Integer> pairs = new HashMap<Integer, Integer>();

Declaring C# Dictionary:

Dictionary<int, int> Pairs = new Dictionary<int, int>();

Getting a value from a location:

pairs.get(input[i]); // in Java
Pairs[input[i]];     // in C#

Setting a value at location:

pairs.put(k - input[i], input[i]); // in Java
Pairs[k - input[i]] = input[i];    // in C#

An Overall Example can be observed from below Codaddict's algorithm.

codaddict's algorithm in Java:

import java.util.HashMap;

public class ArrayPairSum {

    public static void printSumPairs(int[] input, int k)
    {
        Map<Integer, Integer> pairs = new HashMap<Integer, Integer>();

        for (int i = 0; i < input.length; i++)
        {
            if (pairs.containsKey(input[i]))
                System.out.println(input[i] + ", " + pairs.get(input[i]));
            else
                pairs.put(k - input[i], input[i]);
        }

    }

    public static void main(String[] args)
    {
        int[] a = { 2, 45, 7, 3, 5, 1, 8, 9 };
        printSumPairs(a, 10);

    }
}

Codaddict's algorithm in C#

using System;
using System.Collections.Generic;

class Program
{
    static void checkPairs(int[] input, int k)
    {
        Dictionary<int, int> Pairs = new Dictionary<int, int>();

        for (int i = 0; i < input.Length; i++)
        {
            if (Pairs.ContainsKey(input[i]))
            {
                Console.WriteLine(input[i] + ", " + Pairs[input[i]]);
            }
            else
            {
                Pairs[k - input[i]] = input[i];
            }
        }
    }
    static void Main(string[] args)
    {
        int[] a = { 2, 45, 7, 3, 5, 1, 8, 9 };
        //method : codaddict's algorithm : O(n)
        checkPairs(a, 10);
        Console.Read();
    }
}

If you want to add a sourceSet for testing in addition to all the existing ones, within a module regardless of the active flavor:

sourceSets {
    test {
        java.srcDirs += [
                'src/customDir/test/kotlin'
        ]
        print(java.srcDirs)   // Clean
    }
}

Pay attention to the operator += and if you want to run integration tests change test to androidTest.

Yes, open a postscript() device with a filename ending in .eps, do your plot(s) and call dev.off().

Anaconda does not use the PYTHONPATH. One should however note that if the PYTHONPATH is set it could be used to load a library that is not in the anaconda environment. That is why before activating an environment it might be good to do a

unset PYTHONPATH

For instance this PYTHONPATH points to an incorrect pandas lib:

export PYTHONPATH=/home/john/share/usr/anaconda/lib/python
source activate anaconda-2.7
python
>>>> import pandas as pd
/home/john/share/usr/lib/python/pandas-0.12.0-py2.7-linux-x86_64.egg/pandas/hashtable.so: undefined symbol: PyUnicodeUCS2_DecodeUTF8
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/john/share/usr/lib/python/pandas-0.12.0-py2.7-linux-x86_64.egg/pandas/__init__.py", line 6, in <module>
    from . import hashtable, tslib, lib
ImportError: /home/john/share/usr/lib/python/pandas-0.12.0-py2.7-linux-x86_64.egg/pandas/hashtable.so: undefined symbol: PyUnicodeUCS2_DecodeUTF8

unsetting the PYTHONPATH prevents the wrong pandas lib from being loaded:

unset PYTHONPATH
source activate anaconda-2.7
python
>>>> import pandas as pd
>>>>

Have you tried DATENAME(MONTH, S0.OrderDateTime) ?

I had exact issue and here is how I fixed:

I found out that I had first installed Keras then installed pandas in my virtual env. When you install keras, pandas is shipped with it. Do not need to pip install pandas.

I tested this hypothesis by creating new virtual environment and wala... pandas appeared without me installing it. Thus I came to the conclusion that pandas is automatically installed when you pip install keras.

I also had this issue and my solution was different, so adding here for any who have similar problem.

My controller had:

@RequestMapping(value = "/setPassword", method = RequestMethod.POST)
public String setPassword(Model model, @RequestParameter SetPassword setPassword) {
    ...
}

The issue was that this should be @ModelAttribute for the object, not @RequestParameter. The error message for this is the same as you describe in your question.

@RequestMapping(value = "/setPassword", method = RequestMethod.POST)
public String setPassword(Model model, @ModelAttribute SetPassword setPassword) {
    ...
}

If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user, picked from your example), then the syntax is quite simple:

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin('a.user', 'u')
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

Since you are applying a condition on the joined result here, using a LEFT JOIN or simply JOIN is the same.

If no association is available, then the query looks like following

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin(
            'User\Entity\User',
            'u',
            \Doctrine\ORM\Query\Expr\Join::WITH,
            'a.user = u.id'
        )
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

This will produce a resultset that looks like following:

array(
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    // ...
)

If you're iterating over an object instead of an array, you'll need to access the properties using:

$id = $blog->id;
$title = $blog->title;
$content = $blog->content;

That, or change your object to an array.

I had a different approach. I've sub-classed a Thread class and in the constructor I've created an Event object. Then I've written custom join() method, which first sets this event and then calls a parent's version of itself.

Here is my class, I'm using for serial port communication in wxPython app:

import wx, threading, serial, Events, Queue

class PumpThread(threading.Thread):

    def __init__ (self, port, queue, parent):
        super(PumpThread, self).__init__()
        self.port = port
        self.queue = queue
        self.parent = parent

        self.serial = serial.Serial()
        self.serial.port = self.port
        self.serial.timeout = 0.5
        self.serial.baudrate = 9600
        self.serial.parity = 'N'

        self.stopRequest = threading.Event()

    def run (self):
        try:
            self.serial.open()
        except Exception, ex:
            print ("[ERROR]\tUnable to open port {}".format(self.port))
            print ("[ERROR]\t{}\n\n{}".format(ex.message, ex.traceback))
            self.stopRequest.set()
        else:
            print ("[INFO]\tListening port {}".format(self.port))
            self.serial.write("FLOW?\r")

        while not self.stopRequest.isSet():
            msg = ''
            if not self.queue.empty():
                try:
                    command = self.queue.get()
                    self.serial.write(command)
                except Queue.Empty:
                    continue

            while self.serial.inWaiting():
                char = self.serial.read(1)
                if '\r' in char and len(msg) > 1:
                    char = ''
                    #~ print('[DATA]\t{}'.format(msg))
                    event = Events.PumpDataEvent(Events.SERIALRX, wx.ID_ANY, msg)
                    wx.PostEvent(self.parent, event)
                    msg = ''
                    break
                msg += char
        self.serial.close()

    def join (self, timeout=None):
        self.stopRequest.set()
        super(PumpThread, self).join(timeout)

    def SetPort (self, serial):
        self.serial = serial

    def Write (self, msg):
        if self.serial.is_open:
            self.queue.put(msg)
        else:
            print("[ERROR]\tPort {} is not open!".format(self.port))

    def Stop(self):
        if self.isAlive():
            self.join()

The Queue is used for sending messages to the port and main loop takes responses back. I've used no serial.readline() method, because of different end-line char, and I have found the usage of io classes to be too much fuss.

Use position: fixed instead of position: absolute.

See here.

Bounds checked:

 [a[index] for index in (1,2,5,20) if 0 <= index < len(a)]
 # [11, 12, 15] 

Because of things like this, as a general rule of thumb, I try to avoid as much XAML "trickery" as possible and keep the XAML as dumb and simple as possible and do the rest in the ViewModel (or attached properties or IValueConverters etc. if really necessary).

If possible I would give the ViewModel of the current DataContext a reference (i.e. property) to the relevant parent ViewModel

public class ThisViewModel : ViewModelBase
{
    TypeOfAncestorViewModel Parent { get; set; }
}

and bind against that directly instead.

<TextBox Text="{Binding Parent}" />

In Python 3 you can use a variation on:

def Deb(msg = None):
  print(f"Debug {sys._getframe().f_back.f_lineno}: {msg if msg is not None else ''}")

In code, you can then use:

Deb("Some useful information")
Deb()

To produce:

123: Some useful information
124:

Where the 123 and 124 are the lines that the calls are made from.

How can I get the item name "Mon, Tue, etc" when I already have the item value "0, 1, etc."

On some older C code (quite some time ago), I found code analogous to:

std::string weekEnumToStr(int n)
{
   std::string s("unknown");
   switch (n)
   {
   case 0: { s = "Mon"; } break;
   case 1: { s = "Tue"; } break;
   case 2: { s = "Wed"; } break;
   case 3: { s = "Thu"; } break;
   case 4: { s = "Fri"; } break;
   case 5: { s = "Sat"; } break;
   case 6: { s = "Sun"; } break;
   }
   return s;
}

Con: This establishes a "pathological dependency" between the enumeration values and the function... meaning if you change the enum you must change the function to match. I suppose this is true even for a std::map.

I vaguely remember we found a utility to generate the function code from the enum code. The enum table length had grown to several hundred ... and at some point it is maybe a sound choice to write code to write code.

Note -

in an embedded system enhancement effort, my team replaced many tables (100+?) of null-terminated-strings used to map enum int values to their text strings.

The problem with the tables was that a value out of range was often not noticed because many of these tables were gathered into one region of code / memory, such that a value out-of-range reached past the named table end(s) and returned a null-terminated-string from some subsequent table.

Using the function-with-switch statement also allowed us to add an assert in the default clause of the switch. The asserts found several more coding errors during test, and our asserts were tied into a static-ram-system-log our field techs could search.

Do not hesitate to put constraints on the database. You'll be sure to have a consistent database, and that's one of the good reasons to use a database. Especially if you have several applications requesting it (or just one application but with a direct mode and a batch mode using different sources).

With MySQL you do not have advanced constraints like you would have in postgreSQL but at least the foreign key constraints are quite advanced.

We'll take an example, a company table with a user table containing people from theses company

CREATE TABLE COMPANY (
     company_id INT NOT NULL,
     company_name VARCHAR(50),
     PRIMARY KEY (company_id)
) ENGINE=INNODB;

CREATE TABLE USER (
     user_id INT, 
     user_name VARCHAR(50), 
     company_id INT,
     INDEX company_id_idx (company_id),
     FOREIGN KEY (company_id) REFERENCES COMPANY (company_id) ON...
) ENGINE=INNODB;

Let's look at the ON UPDATE clause:

• ON UPDATE RESTRICT : the default : if you try to update a company_id in table COMPANY the engine will reject the operation if one USER at least links on this company.
• ON UPDATE NO ACTION : same as RESTRICT.
• ON UPDATE CASCADE : the best one usually : if you update a company_id in a row of table COMPANY the engine will update it accordingly on all USER rows referencing this COMPANY (but no triggers activated on USER table, warning). The engine will track the changes for you, it's good.
• ON UPDATE SET NULL : if you update a company_id in a row of table COMPANY the engine will set related USERs company_id to NULL (should be available in USER company_id field). I cannot see any interesting thing to do with that on an update, but I may be wrong.

And now on the ON DELETE side:

• ON DELETE RESTRICT : the default : if you try to delete a company_id Id in table COMPANY the engine will reject the operation if one USER at least links on this company, can save your life.
• ON DELETE NO ACTION : same as RESTRICT
• ON DELETE CASCADE : dangerous : if you delete a company row in table COMPANY the engine will delete as well the related USERs. This is dangerous but can be used to make automatic cleanups on secondary tables (so it can be something you want, but quite certainly not for a COMPANY<->USER example)
• ON DELETE SET NULL : handful : if you delete a COMPANY row the related USERs will automatically have the relationship to NULL. If Null is your value for users with no company this can be a good behavior, for example maybe you need to keep the users in your application, as authors of some content, but removing the company is not a problem for you.

usually my default is: ON DELETE RESTRICT ON UPDATE CASCADE. with some ON DELETE CASCADE for track tables (logs--not all logs--, things like that) and ON DELETE SET NULL when the master table is a 'simple attribute' for the table containing the foreign key, like a JOB table for the USER table.

Edit

It's been a long time since I wrote that. Now I think I should add one important warning. MySQL has one big documented limitation with cascades. Cascades are not firing triggers. So if you were over confident enough in that engine to use triggers you should avoid cascades constraints.

• http://dev.mysql.com/doc/refman/5.6/en/triggers.html

MySQL triggers activate only for changes made to tables by SQL statements. They do not activate for changes in views, nor by changes to tables made by APIs that do not transmit SQL statements to the MySQL Server

• http://dev.mysql.com/doc/refman/5.6/en/stored-program-restrictions.html#stored-routines-trigger-restrictions

==> See below the last edit, things are moving on this domain

Triggers are not activated by foreign key actions.

And I do not think this will get fixed one day. Foreign key constraints are managed by the InnoDb storage and Triggers are managed by the MySQL SQL engine. Both are separated. Innodb is the only storage with constraint management, maybe they'll add triggers directly in the storage engine one day, maybe not.

But I have my own opinion on which element you should choose between the poor trigger implementation and the very useful foreign keys constraints support. And once you'll get used to database consistency you'll love PostgreSQL.

12/2017-Updating this Edit about MySQL:

as stated by @IstiaqueAhmed in the comments, the situation has changed on this subject. So follow the link and check the real up-to-date situation (which may change again in the future).

When you find it necessary to update a primary key value as well as all matching foreign keys, then the entire design needs to be fixed.

It is tricky to cascade all the necessary foreign keys changes. It is a best practice to never update the primary key, and if you find it necessary, you should use a Surrogate Primary Key, which is a key not derived from application data. As a result its value is unrelated to the business logic and never needs to change (and should be invisible to the end user). You can then update and display some other column.

for example:

BadUserTable
UserID     varchar(20) primary key --user last name
other columns...

when you create many tables that have a FK to UserID, to track everything that the user has worked on, but that user then gets married and wants a ID to match their new last name, you are out of luck.

GoodUserTable
UserID    int identity(1,1) primary key
UserLogin varchar(20) 
other columns....

you now FK the Surrogate Primary Key to all the other tables, and display UserLogin when necessary, allow them to login using that value, and when they need to change it, you change it in one column of one row only.

You want:

this.value = ''; // straight JS, no jQuery

or

$(this).val(''); // jQuery

With $(this).value = '' you're assigning an empty string as the value property of the jQuery object that wraps this -- not the value of this itself.

So as far as AJAX is concerned...

Pressing back while using most web-apps that use AJAX to navigate specific parts of a page is a HUGE issue. I don't accept that 'having to disable the button means you're doing something wrong' and in fact developers in different facets have long run into this problem. Here's my solution:

window.onload = function () {
    if (typeof history.pushState === "function") {
        history.pushState("jibberish", null, null);
        window.onpopstate = function () {
            history.pushState('newjibberish', null, null);
            // Handle the back (or forward) buttons here
            // Will NOT handle refresh, use onbeforeunload for this.
        };
    }
    else {
        var ignoreHashChange = true;
        window.onhashchange = function () {
            if (!ignoreHashChange) {
                ignoreHashChange = true;
                window.location.hash = Math.random();
                // Detect and redirect change here
                // Works in older FF and IE9
                // * it does mess with your hash symbol (anchor?) pound sign
                // delimiter on the end of the URL
            }
            else {
                ignoreHashChange = false;   
            }
        };
    }
}

As far as Ive been able to tell this works across chrome, firefox, haven't tested IE yet.

In Jake's ViewPageIndicator he has implemented View pager to display a String array (i.e. ["this","is","a","text"]) which you pass from YourAdapter.java (that extends FragmentPagerAdapter) to the YourFragment.java which returns a View to the viewpager.

In order to display something different, you simply have to change the context type your passing. In this case you want to pass images instead of text, as shown in the sample below:

This is how you setup your Viewpager:

public class PlaceDetailsFragment extends SherlockFragment {
    PlaceSlidesFragmentAdapter mAdapter;
    ViewPager mPager;
    PageIndicator mIndicator;

    public static final String TAG = "detailsFragment";

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_place_details,
                container, false);

        mAdapter = new PlaceSlidesFragmentAdapter(getActivity()
                .getSupportFragmentManager());

        mPager = (ViewPager) view.findViewById(R.id.pager);
        mPager.setAdapter(mAdapter);

        mIndicator = (CirclePageIndicator) view.findViewById(R.id.indicator);
        mIndicator.setViewPager(mPager);
        ((CirclePageIndicator) mIndicator).setSnap(true);

        mIndicator
                .setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
                    @Override
                    public void onPageSelected(int position) {
                        Toast.makeText(PlaceDetailsFragment.this.getActivity(),

You should get a View pager like this from the above code.

Please be aware that some answers in this thread suggesting use $[] is WRONG.

db.collection.update(
   {"events.profile":10},
   {$set:{"events.$[].handled":0}},
   {multi:true}
)

The above code will update "handled" to 0 for all elements in "events" array, regardless of its "profile" value. The query {"events.profile":10} is only to filter the whole document, not the documents in the array. In this situation it is a must to use $[elem] with arrayFilters to specify the condition of array items so Neil Lunn's answer is correct.

The lstrip() method will remove leading whitespaces, newline and tab characters on a string beginning:

>>> '     hello world!'.lstrip()
'hello world!'

Edit

As balpha pointed out in the comments, in order to remove only spaces from the beginning of the string, lstrip(' ') should be used:

>>> '   hello world with 2 spaces and a tab!'.lstrip(' ')
'\thello world with 2 spaces and a tab!'

• Trimming a string in Python

You can also use this

let str = "hello single ' double \" and slash \\ yippie";

let escapeStr = escape(str);
document.write("<b>str : </b>"+str);
document.write("<br/><b>escapeStr : </b>"+escapeStr);
document.write("<br/><b>unEscapeStr : </b> "+unescape(escapeStr));

This works with Bootstrap 4.1.3:

    $("input[type=file]").change(function () {
        var fieldVal = $(this).val();

        // Change the node's value by removing the fake path (Chrome)
        fieldVal = fieldVal.replace("C:\\fakepath\\", "");

        if (fieldVal != undefined || fieldVal != "") {
            $(this).next(".custom-file-label").attr('data-content', fieldVal);
            $(this).next(".custom-file-label").text(fieldVal);
        }
    });
</script>

Microsoft API Code Pack. ShellObjectWatcher class.

Google used to recommend putting it just before the </body> tag, because the original method they provided for loading ga.js was blocking. The newer async syntax, though, can safely be put in the head with minimal blockage, so the current recommendation is just before the </head> tag.

<head> will add a little latency; in the footer will reduce the number of pageviews recorded at some small margin. It's a tradeoff. ga.js is heavily cached and present on a large percentage of sites across the web, so its often served from the cache, reducing latency to almost nil.

As a matter of personal preference, I like to include it in the <head>, but its really a matter of preference.

What about a parallel implementation

public static void InitializeArray<T>(T[] array, T value)
{
    var cores = Environment.ProcessorCount;

    ArraySegment<T>[] segments = new ArraySegment<T>[cores];

    var step = array.Length / cores;
    for (int i = 0; i < cores; i++)
    {
        segments[i] = new ArraySegment<T>(array, i * step, step);
    }
    var remaining = array.Length % cores;
    if (remaining != 0)
    {
        var lastIndex = segments.Length - 1;
        segments[lastIndex] = new ArraySegment<T>(array, lastIndex * step, array.Length - (lastIndex * step));
    }

    var initializers = new Task[cores];
    for (int i = 0; i < cores; i++)
    {
        var index = i;
        var t = new Task(() =>
        {
            var s = segments[index];
            for (int j = 0; j < s.Count; j++)
            {
                array[j + s.Offset] = value;
            }
        });
        initializers[i] = t;
        t.Start();
    }

    Task.WaitAll(initializers);
}

When only initializing an array the power of this code can't be seen but I think you should definitely forget about the "pure" for.

This seems a lot cleaner than the answer above...

var maxID = 0;
function getTemplateRow() {
var x = document.getElementById("templateRow").cloneNode(true);
x.id = "";
x.style.display = "";
x.innerHTML = x.innerHTML.replace(/{id}/, ++maxID);
return x;
}
function addRow() {
var t = document.getElementById("theTable");
var rows = t.getElementsByTagName("tr");
var r = rows[rows.length - 1];
r.parentNode.insertBefore(getTemplateRow(), r);

}
</script>


<table id="theTable">
<tr>
<td>id</td>
<td>name</td>
</tr>
<tr id="templateRow" style="display:none">

<td><input /></td>
</tr>
</table>

Although already over a year old, I stumbled across this question a couple of times on other Google search and I believe I can improve on the previous answer for the benefit of others.

Short answer is you cannot combine both action in one line, but you can create a chain that does what you want and then call it in a one liner.

Let's create a chain to log and accept:

iptables -N LOG_ACCEPT

And let's populate its rules:

iptables -A LOG_ACCEPT -j LOG --log-prefix "INPUT:ACCEPT:" --log-level 6
iptables -A LOG_ACCEPT -j ACCEPT

Now let's create a chain to log and drop:

iptables -N LOG_DROP

And let's populate its rules:

iptables -A LOG_DROP -j LOG --log-prefix "INPUT:DROP: " --log-level 6
iptables -A LOG_DROP -j DROP

Now you can do all actions in one go by jumping (-j) to you custom chains instead of the default LOG / ACCEPT / REJECT / DROP:

iptables -A <your_chain_here> <your_conditions_here> -j LOG_ACCEPT
iptables -A <your_chain_here> <your_conditions_here> -j LOG_DROP

Although an old question all the contributions helped me a lot so here's my solution, which works within my own DbContext class. The $rows parameter is simply an array of associative arrays representing rows or models: field name => insert value.

If you use a pattern that uses models this fits in nicely when passed model data as an array, say from a ToRowArray method within the model class.

Note: It should go without saying but never allow the arguments passed to this method to be exposed to the user or reliant on any user input, other than the insert values, which have been validated and sanitised. The $tableName argument and the column names should be defined by the calling logic; for instance a User model could be mapped to the user table, which has its column list mapped to the model's member fields.

public function InsertRange($tableName, $rows)
{
    // Get column list
    $columnList = array_keys($rows[0]);
    $numColumns = count($columnList);
    $columnListString = implode(",", $columnList);

    // Generate pdo param placeholders
    $placeHolders = array();

    foreach($rows as $row)
    {
        $temp = array();

        for($i = 0; $i < count($row); $i++)
            $temp[] = "?";

        $placeHolders[] = "(" . implode(",", $temp) . ")";
    }

    $placeHolders = implode(",", $placeHolders);

    // Construct the query
    $sql = "insert into $tableName ($columnListString) values $placeHolders";
    $stmt = $this->pdo->prepare($sql);

    $j = 1;
    foreach($rows as $row)
    {
        for($i = 0; $i < $numColumns; $i++)
        {
            $stmt->bindParam($j, $row[$columnList[$i]]);
            $j++;
        }
    }

    $stmt->execute();
}

I uninstall Only Android studio (keep the SDK and Emulator) and then reinstall it just android studio. took me 2 minutes and my android studio work again.

There is no "standard place" for a sqlite database. The file's location is specified to the library, and may be in your home directory, in the invoking program's folder, or any other place.

If it helps, sqlite databases are, by convention, named with a .db file extension.

The only way you should be getting values "out of" an Observable/Subject is with subscribe!

If you're using getValue() you're doing something imperative in declarative paradigm. It's there as an escape hatch, but 99.9% of the time you should NOT use getValue(). There are a few interesting things that getValue() will do: It will throw an error if the subject has been unsubscribed, it will prevent you from getting a value if the subject is dead because it's errored, etc. But, again, it's there as an escape hatch for rare circumstances.

There are several ways of getting the latest value from a Subject or Observable in a "Rx-y" way:

1. Using BehaviorSubject: But actually subscribing to it. When you first subscribe to BehaviorSubject it will synchronously send the previous value it received or was initialized with.
2. Using a ReplaySubject(N): This will cache N values and replay them to new subscribers.
3. A.withLatestFrom(B): Use this operator to get the most recent value from observable B when observable A emits. Will give you both values in an array [a, b].
4. A.combineLatest(B): Use this operator to get the most recent values from A and B every time either A or B emits. Will give you both values in an array.
5. shareReplay(): Makes an Observable multicast through a ReplaySubject, but allows you to retry the observable on error. (Basically it gives you that promise-y caching behavior).
6. publishReplay(), publishBehavior(initialValue), multicast(subject: BehaviorSubject | ReplaySubject), etc: Other operators that leverage BehaviorSubject and ReplaySubject. Different flavors of the same thing, they basically multicast the source observable by funneling all notifications through a subject. You need to call connect() to subscribe to the source with the subject.

Appending single space to output file with stream variable.

// declare output file stream varaible and open file ofstream fout; fout.open("flux_capacitor.txt"); fout << var << " ";

Since you've got both the shell that you're typing into and the shell that sudo -s runs, you need to quote or escape twice. (EDITED fixed quoting)

sudo -su db2inst1 '/opt/ibm/db2/V9.7/bin/db2 force application \(1995\)'

or

sudo -su db2inst1 /opt/ibm/db2/V9.7/bin/db2 force application \\\(1995\\\)

Out of curiosity, why do you need -s? Can't you just do this:

sudo -u db2inst1 /opt/ibm/db2/V9.7/bin/db2 force application \(1995\)

Look in the \application\config\config.php file, there is a variable named index_page

It should look like this

$config['index_page'] = "index.php";

change it to

$config['index_page'] = "";

Then as mentioned you also need to add a rewrite rule to the .htaccess file like this:

RewriteEngine on
RewriteCond $1 !^(index\\.php|resources|robots\\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

It work for me, hope you too.

What about this:

while ($row = mysql_fetch_array($result)) 
{
    $new_array[$row['id']]['id'] = $row['id'];
    $new_array[$row['id']]['link'] = $row['link'];
}

To retrieve link and id:

foreach($new_array as $array)
{       
   echo $array['id'].'<br />';
   echo $array['link'].'<br />';
}

Intellij User, make sure you have 3 things,

1. Lombok dependency

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.8</version>
            <scope>provided</scope>
        </dependency>

2. IntelliJ plugin for Lombok

3. Lombok annotation, like @Getter @Setter (make sure it is coming from lombok and not from somewhere else)

and it should work.

The MySQL Administrator (part of the MySQL GUI Tools) can do that for you on a database level.

Just select your schema and press the Maintenance button in the bottom right corner.

Since the GUI Tools have reached End-of-life status they are hard to find on the mysql page. Found them via Google: http://dev.mysql.com/downloads/gui-tools/5.0.html

I don't know if the new MySQL Workbench can do that, too.

And you can use the mysqlcheck command line tool which should be able to do that, too.

My solution is entrypoint2. Example:

from entrypoint2 import entrypoint
@entrypoint
def add(file, quiet=True): 
    ''' This function writes report.

    :param file: write report to FILE
    :param quiet: don't print status messages to stdout
    '''
    print file,quiet

help text:

usage: report.py [-h] [-q] [--debug] file

This function writes report.

positional arguments:
  file         write report to FILE

optional arguments:
  -h, --help   show this help message and exit
  -q, --quiet  don't print status messages to stdout
  --debug      set logging level to DEBUG

I usually use like this:

 var x = object.any ? object.any.a : 'def';

All rendering is based on OpenGL, so no you can't go over this limit (GL_MAX_TEXTURE_SIZE depends on the device, but the minimum is 2048x2048, so any image lower than 2048x2048 will fit).

With such big images, if you want to zoom in out, and in a mobile, you should setup a system similar to what you see in google maps for example. With the image split in several pieces, and several definitions.

Or you could scale down the image before displaying it (see user1352407's answer on this question).

And also, be careful to which folder you put the image into, Android can automatically scale up images. Have a look at Pilot_51's answer below on this question.

Translated from here:

Dimension getScaledDimension(Dimension imageSize, Dimension boundary) {

    double widthRatio = boundary.getWidth() / imageSize.getWidth();
    double heightRatio = boundary.getHeight() / imageSize.getHeight();
    double ratio = Math.min(widthRatio, heightRatio);

    return new Dimension((int) (imageSize.width  * ratio),
                         (int) (imageSize.height * ratio));
}

You can also use imgscalr to resize images while maintaining aspect ratio:

BufferedImage resizeMe = ImageIO.read(new File("orig.jpg"));
Dimension newMaxSize = new Dimension(255, 255);
BufferedImage resizedImg = Scalr.resize(resizeMe, Method.QUALITY,
                                        newMaxSize.width, newMaxSize.height);

Swift 4.0

func rotateImageView()
{
    UIView.animate(withDuration: 0.3, delay: 0, options: .curveLinear, animations: {() -> Void in
        self.imageView.transform = self.imageView.transform.rotated(by: .pi / 2)
    }, completion: {(_ finished: Bool) -> Void in
        if finished {
            rotateImageView()
        }
    })
}

Oh, I found it. You use last instead of break

for my $entry (@array){
    if ($string eq "text"){
         last;
    }
}

On OSX the following works from the command line:

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --allow-running-insecure-content

I modified my response to include the code for a test app I did.

Update: I have updated the jQuery to set the 'traditional' setting to true so this will work again (per @DustinDavis' answer).

First the javascript:

function test()
{
    var stringArray = new Array();
    stringArray[0] = "item1";
    stringArray[1] = "item2";
    stringArray[2] = "item3";
    var postData = { values: stringArray };

    $.ajax({
        type: "POST",
        url: "/Home/SaveList",
        data: postData,
        success: function(data){
            alert(data.Result);
        },
        dataType: "json",
        traditional: true
    });
}

And here's the code in my controller class:

public JsonResult SaveList(List<String> values)
{
    return Json(new { Result = String.Format("Fist item in list: '{0}'", values[0]) });
}

When I call that javascript function, I get an alert saying "First item in list: 'item1'". Hope this helps!

Use

git apply patchfile

if possible.

patch -p1 < patchfile 

has potential side-effect.

git apply also handles file adds, deletes, and renames if they're described in the git diff format, which patch won't do. Finally, git apply is an "apply all or abort all" model where either everything is applied or nothing is, whereas patch can partially apply patch files, leaving your working directory in a weird state.

I'm not able to comment (not enough reputation) so I'll amend Luis Rosety's answer here:

function between($n, $a, $b) {
    return ($n-$a)*($n-$b) <= 0;
}

This function works also in cases where n == a or n == b.

Proof: Let n belong to range [a,b], where [a,b] is a subset of real numbers.

Now a <= n <= b. Then n-a >= 0 and n-b <= 0. That means that (n-a)*(n-b) <= 0.

Case b <= n <= a works similarly.

To remove also the [] use:

\[.+\]

I know my solution is not very popular from the pythonic point of view, but I prefer to use the Java approach of one module->one class, with the module named as the class. I do understand the reason behind the python style, but I am not too fond of having a very large file containing a lot of classes. I find it difficult to browse, despite folding.

Another reason is version control: having a large file means that your commits tend to concentrate on that file. This can potentially lead to a higher quantity of conflicts to be resolved. You also loose the additional log information that your commit modifies specific files (therefore involving specific classes). Instead you see a modification to the module file, with only the commit comment to understand what modification has been done.

Summing up, if you prefer the python philosophy, go for the suggestions of the other posts. If you instead prefer the java-like philosophy, create a Nib.py containing class Nib.

The Authenticity Token is rails' method to prevent 'cross-site request forgery (CSRF or XSRF) attacks'.

To put it simple, it makes sure that the PUT / POST / DELETE (methods that can modify content) requests to your web app are made from the client's browser and not from a third party (an attacker) that has access to a cookie created on the client side.

Please try:

str1.contains(str2)

You can add the android:textAllCaps="true" property to your xml file in the EditText. This will enforce the softinput keyboard to appear in all caps mode. The value you enter will appear in Uppercase. However, this won't ensure that the user can only enter in UpperCase letters. If they want, they can still fall back to the lower case letters. If you want to ensure that the output of the Edittext is in All caps, then you have to manually convert the input String using toUpperCase() method of String class.

I've been in a situation like you (JPA/Hibernate sequence for non @Id field) and I ended up creating a trigger in my db schema that add a unique sequence number on insert. I just never got it to work with JPA/Hibernate

You have two versions of ADB

$ /usr/local/bin/adb version
Android Debug Bridge version 1.0.36
Revision 0e9850346394-android

and

$ /Users/user/Library/Android/sdk/platform-tools/adb version
Android Debug Bridge version 1.0.39
Revision 3db08f2c6889-android

You could see which one your PATH is pointing to (echo $PATH) but I fixed it with a adb stop-server on one version and a adb start-server on the other.

A one liner shell script to remove a file if it already exist (based on Jindra Helcl's answer):

[ -f file ] && rm file

or with a variable:

#!/bin/bash

file="/path/to/file.ext"
[ -f $file ] && rm $file

Not sure what you call FIFO these days since Queue is FILO, but when I was a student we used the Stack<E> with the simple push, pop, and a peek... It is really that simple, no need for complicating further with Queue and whatever the accepted answer suggests.

If you are writing a module in your own code for a specific usage, majkinetor's method MIGHT have worked. But there are some problems.

First, the official document does NOT guarantee that the GetHashCode() returns an unique identifier (see Object.GetHashCode Method ()):

You should not assume that equal hash codes imply object equality.

Second, assume you have a very small amount of objects so that GetHashCode() will work in most cases, this method can be overridden by some types.
For example, you are using some class C and it overrides GetHashCode() to always return 0. Then every object of C will get the same hash code. Unfortunately, Dictionary, HashTable and some other associative containers will make use this method:

A hash code is a numeric value that is used to insert and identify an object in a hash-based collection such as the Dictionary<TKey, TValue> class, the Hashtable class, or a type derived from the DictionaryBase class. The GetHashCode method provides this hash code for algorithms that need quick checks of object equality.

So, this approach has great limitations.

And even more, what if you want to build a general purpose library? Not only are you not able to modify the source code of the used classes, but their behavior is also unpredictable.

I appreciate that Jon and Simon have posted their answers, and I will post a code example and a suggestion on performance below.

using System.Diagnostics;
using System.Runtime.CompilerServices;
using System.Runtime.Serialization;
using System.Collections.Generic;


namespace ObjectSet
{
    public interface IObjectSet
    {
        /// <summary> check the existence of an object. </summary>
        /// <returns> true if object is exist, false otherwise. </returns>
        bool IsExist(object obj);

        /// <summary> if the object is not in the set, add it in. else do nothing. </summary>
        /// <returns> true if successfully added, false otherwise. </returns>
        bool Add(object obj);
    }

    public sealed class ObjectSetUsingConditionalWeakTable : IObjectSet
    {
        /// <summary> unit test on object set. </summary>
        internal static void Main() {
            Stopwatch sw = new Stopwatch();
            sw.Start();
            ObjectSetUsingConditionalWeakTable objSet = new ObjectSetUsingConditionalWeakTable();
            for (int i = 0; i < 10000000; ++i) {
                object obj = new object();
                if (objSet.IsExist(obj)) { Console.WriteLine("bug!!!"); }
                if (!objSet.Add(obj)) { Console.WriteLine("bug!!!"); }
                if (!objSet.IsExist(obj)) { Console.WriteLine("bug!!!"); }
            }
            sw.Stop();
            Console.WriteLine(sw.ElapsedMilliseconds);
        }


        public bool IsExist(object obj) {
            return objectSet.TryGetValue(obj, out tryGetValue_out0);
        }

        public bool Add(object obj) {
            if (IsExist(obj)) {
                return false;
            } else {
                objectSet.Add(obj, null);
                return true;
            }
        }

        /// <summary> internal representation of the set. (only use the key) </summary>
        private ConditionalWeakTable<object, object> objectSet = new ConditionalWeakTable<object, object>();

        /// <summary> used to fill the out parameter of ConditionalWeakTable.TryGetValue(). </summary>
        private static object tryGetValue_out0 = null;
    }

    [Obsolete("It will crash if there are too many objects and ObjectSetUsingConditionalWeakTable get a better performance.")]
    public sealed class ObjectSetUsingObjectIDGenerator : IObjectSet
    {
        /// <summary> unit test on object set. </summary>
        internal static void Main() {
            Stopwatch sw = new Stopwatch();
            sw.Start();
            ObjectSetUsingObjectIDGenerator objSet = new ObjectSetUsingObjectIDGenerator();
            for (int i = 0; i < 10000000; ++i) {
                object obj = new object();
                if (objSet.IsExist(obj)) { Console.WriteLine("bug!!!"); }
                if (!objSet.Add(obj)) { Console.WriteLine("bug!!!"); }
                if (!objSet.IsExist(obj)) { Console.WriteLine("bug!!!"); }
            }
            sw.Stop();
            Console.WriteLine(sw.ElapsedMilliseconds);
        }


        public bool IsExist(object obj) {
            bool firstTime;
            idGenerator.HasId(obj, out firstTime);
            return !firstTime;
        }

        public bool Add(object obj) {
            bool firstTime;
            idGenerator.GetId(obj, out firstTime);
            return firstTime;
        }


        /// <summary> internal representation of the set. </summary>
        private ObjectIDGenerator idGenerator = new ObjectIDGenerator();
    }
}

In my test, the ObjectIDGenerator will throw an exception to complain that there are too many objects when creating 10,000,000 objects (10x than in the code above) in the for loop.

Also, the benchmark result is that the ConditionalWeakTable implementation is 1.8x faster than the ObjectIDGenerator implementation.

Loop like

foreach (GridViewRow row in grid.Rows)
{
   if (((CheckBox)row.FindControl("chkboxid")).Checked)
   {
    //read the label            
   }            
}

The Tuple approach :

This solution provides a strict FixedLengthArray (ak.a. SealedArray) type signature based in Tuples.

Syntax example :

// Array containing 3 strings
let foo : FixedLengthArray<[string, string, string]> 

This is the safest approach, considering it prevents accessing indexes out of the boundaries.

Implementation :

type ArrayLengthMutationKeys = 'splice' | 'push' | 'pop' | 'shift' | 'unshift' | number
type ArrayItems<T extends Array<any>> = T extends Array<infer TItems> ? TItems : never
type FixedLengthArray<T extends any[]> =
  Pick<T, Exclude<keyof T, ArrayLengthMutationKeys>>
  & { [Symbol.iterator]: () => IterableIterator< ArrayItems<T> > }

Tests :

var myFixedLengthArray: FixedLengthArray< [string, string, string]>

// Array declaration tests
myFixedLengthArray = [ 'a', 'b', 'c' ]  // ? OK
myFixedLengthArray = [ 'a', 'b', 123 ]  // ? TYPE ERROR
myFixedLengthArray = [ 'a' ]            // ? LENGTH ERROR
myFixedLengthArray = [ 'a', 'b' ]       // ? LENGTH ERROR

// Index assignment tests 
myFixedLengthArray[1] = 'foo'           // ? OK
myFixedLengthArray[1000] = 'foo'        // ? INVALID INDEX ERROR

// Methods that mutate array length
myFixedLengthArray.push('foo')          // ? MISSING METHOD ERROR
myFixedLengthArray.pop()                // ? MISSING METHOD ERROR

// Direct length manipulation
myFixedLengthArray.length = 123         // ? READ-ONLY ERROR

// Destructuring
var [ a ] = myFixedLengthArray          // ? OK
var [ a, b ] = myFixedLengthArray       // ? OK
var [ a, b, c ] = myFixedLengthArray    // ? OK
var [ a, b, c, d ] = myFixedLengthArray // ? INVALID INDEX ERROR

(*) This solution requires the noImplicitAny typescript configuration directive to be enabled in order to work (commonly recommended practice)

The Array(ish) approach :

This solution behaves as an augmentation of the Array type, accepting an additional second parameter(Array length). Is not as strict and safe as the Tuple based solution.

Syntax example :

let foo: FixedLengthArray<string, 3> 

Keep in mind that this approach will not prevent you from accessing an index out of the declared boundaries and set a value on it.

Implementation :

type ArrayLengthMutationKeys = 'splice' | 'push' | 'pop' | 'shift' |  'unshift'
type FixedLengthArray<T, L extends number, TObj = [T, ...Array<T>]> =
  Pick<TObj, Exclude<keyof TObj, ArrayLengthMutationKeys>>
  & {
    readonly length: L 
    [ I : number ] : T
    [Symbol.iterator]: () => IterableIterator<T>   
  }

Tests :

var myFixedLengthArray: FixedLengthArray<string,3>

// Array declaration tests
myFixedLengthArray = [ 'a', 'b', 'c' ]  // ? OK
myFixedLengthArray = [ 'a', 'b', 123 ]  // ? TYPE ERROR
myFixedLengthArray = [ 'a' ]            // ? LENGTH ERROR
myFixedLengthArray = [ 'a', 'b' ]       // ? LENGTH ERROR

// Index assignment tests 
myFixedLengthArray[1] = 'foo'           // ? OK
myFixedLengthArray[1000] = 'foo'        // ? SHOULD FAIL

// Methods that mutate array length
myFixedLengthArray.push('foo')          // ? MISSING METHOD ERROR
myFixedLengthArray.pop()                // ? MISSING METHOD ERROR

// Direct length manipulation
myFixedLengthArray.length = 123         // ? READ-ONLY ERROR

// Destructuring
var [ a ] = myFixedLengthArray          // ? OK
var [ a, b ] = myFixedLengthArray       // ? OK
var [ a, b, c ] = myFixedLengthArray    // ? OK
var [ a, b, c, d ] = myFixedLengthArray // ? SHOULD FAIL

As suggested by Alan, function 'mapply' applies a function to multiple Multiple Lists or Vector Arguments:

mapply(myfun, arg1, arg2)

See man page: https://stat.ethz.ch/R-manual/R-devel/library/base/html/mapply.html

You could perhaps use the if-let-where clause:

Swift 3:

if let string = string, !string.isEmpty {
    /* string is not blank */
}

Swift 2:

if let string = string where !string.isEmpty {
    /* string is not blank */
}

I use this. It is just about the same thing as the others, but it is just another way to write it.

@ECHO off
set count=0
:Loop
if %count%==[how many times to loop] goto end
::[Commands to execute here]
set count=%count%+1
goto Loop
:end

There are two cases:

• const reference --good idea, sometimes, especially for heavy objects or proxy classes, compiler optimization

• non-const reference --bad idea, sometimes, breaks encapsulations

Both share same issue -- can potentially point to destroyed object...

I would recommend using smart pointers for many situations where you require to return a reference/pointer.

Also, note the following:

There is a formal rule - the C++ Standard (section 13.3.3.1.4 if you are interested) states that a temporary can only be bound to a const reference - if you try to use a non-const reference the compiler must flag this as an error.

A regular REST API uses HTTP as the underlying protocol for communication, which follows the request and response paradigm, meaning the communication involves the client requesting some data or resource from a server, and the server responding back to that client. However, HTTP is a stateless protocol, so every request-response cycle will end up having to repeat the header and metadata information. This incurs additional latency in case of frequently repeated request-response cycles.

With WebSockets, although the communication still starts off as an initial HTTP handshake, it is further upgraded to follow the WebSockets protocol (i.e. if both the server and the client are compliant with the protocol as not all entities support the WebSockets protocol).

Now with WebSockets, it is possible to establish a full-duplex and persistent connection between the client and a server. This means that unlike a request and a response, the connection stays open for as long as the application is running (i.e. it’s persistent), and since it is full-duplex, two-way simultaneous communication is possible i.e now the server is capable of initiating communication and 'push' some data to the client when new data (that the client is interested in) becomes available.

The WebSockets protocol is stateful and allows you to implement the Publish-Subscribe (or Pub/Sub) messaging pattern which is the primary concept used in the real-time technologies where you are able to get new updates in the form of server push without the client having to request (refresh the page) repeatedly. Examples of such applications are Uber car's location tracking, Push Notifications, Stock market prices updating in real-time, chat, multiplayer games, live online collaboration tools, etc.

You can check out a deep dive article on Websockets which explains the history of this protocol, how it came into being, what it’s used for and how you can implement it yourself.

Here's a video from a presentation I did about WebSockets and how they are different from using the regular REST APIs: Standardisation and leveraging the exponential rise in data streaming

Can you try this, you can use content: counter(page);

     @page {
       @bottom-left {
            content: counter(page) "/" counter(pages);
        }
     }

git pull and git rebase are not interchangeable, but they are closely connected.

git pull fetches the latest changes of the current branch from a remote and applies those changes to your local copy of the branch. Generally this is done by merging, i.e. the local changes are merged into the remote changes. So git pull is similar to git fetch & git merge.

Rebasing is an alternative to merging. Instead of creating a new commit that combines the two branches, it moves the commits of one of the branches on top of the other.

You can pull using rebase instead of merge (git pull --rebase). The local changes you made will be rebased on top of the remote changes, instead of being merged with the remote changes.

Atlassian has some excellent documentation on merging vs. rebasing.

If you are running a modern Intel processor make sure HAXM (Intel® Hardware Accelerated Execution Manager) is installed:

1. In Android SDK Manager, ensure the option is ticked (and then installed)

2. Run the HAXM installer via the path below:

   your_sdk_folder\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe
   or
   your_sdk_folder\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm-android.exe
   

This video shows all the required steps which may help you to solve the problem.

For AMD CPUs (or older Intel CPUs without VT-x technology), you will not be able to install this and the best option is to emulate your apps using Genymotion. See: Intel's HAXM equivalent for AMD on Windows OS

Like Jon Skeet says, use the Process.Exited:

proc.StartInfo.FileName = exportPath + @"\" + fileExe;
proc.Exited += new EventHandler(myProcess_Exited);
proc.Start();
inProcess = true;

while (inProcess)
{
    proc.Refresh();
    System.Threading.Thread.Sleep(10);
    if (proc.HasExited)
    {
        inProcess = false;
    }
}

private void myProcess_Exited(object sender, System.EventArgs e)
{
    inProcess = false;
    Console.WriteLine("Exit time:    {0}\r\n" +
      "Exit code:    {1}\r\n", proc.ExitTime, proc.ExitCode);
}

A really simple implementation is:

out = "".join(c for c in asking if c not in ('!','.',':'))

and keep adding any other types of punctuation.

A more efficient way would be

import string
stringIn = "string.with.punctuation!"
out = stringIn.translate(stringIn.maketrans("",""), string.punctuation)

Edit: There is some more discussion on efficiency and other implementations here: Best way to strip punctuation from a string in Python

This Can be Done by Style Property.

<!DOCTYPE html>

</html>

Its Result will be :

Enjoy... Please Note: This works in Higher version of CSS (>3.0).

You can set the CSS of a notebook by calling a stylesheet from any cell. As an example, take a look at the 12 Steps to Navier Stokes course.

In particular, creating a file containing

<style>
    div.cell{
        width:100%;
        margin-left:1%;
        margin-right:auto;
    }
</style>

should give you a starting point. However, it may be necessary to also adjust e.g div.text_cell_render to deal with markdown as well as code cells.

If that file is custom.css then add a cell containing:

from IPython.core.display import HTML
def css_styling():
    styles = open("custom.css", "r").read()
    return HTML(styles)
css_styling()

This will apply all the stylings, and, in particular, change the cell width.

This is probably the simplest one, besides list1.filter(n => list2.includes(n))

var list1 = ['bread', 'ice cream', 'cereals', 'strawberry', 'chocolate']_x000D_
var list2 = ['bread', 'cherry', 'ice cream', 'oats']_x000D_
_x000D_
function check_common(list1, list2){_x000D_
 _x000D_
 list3 = []_x000D_
 for (let i=0; i<list1.length; i++){_x000D_
  _x000D_
  for (let j=0; j<list2.length; j++){ _x000D_
   if (list1[i] === list2[j]){_x000D_
    list3.push(list1[i]);    _x000D_
   }  _x000D_
  }_x000D_
  _x000D_
 }_x000D_
 return list3_x000D_
 _x000D_
}_x000D_
_x000D_
check_common(list1, list2) // ["bread", "ice cream"]

The ionic approach rocks:

https://dotnetzip.codeplex.com/wikipage?title=PS-Examples

supports passwords, other crypto methods, etc.

One advantage your current approach does have is that it will raise an error if multiple rows are returned by the predicate. To reproduce that you can use.

SELECT @currentTerm = currentterm,
       @termID = termid,
       @endDate = enddate
FROM   table1
WHERE  iscurrent = 1

IF( @@ROWCOUNT <> 1 )
  BEGIN
      RAISERROR ('Unexpected number of matching rows',
                 16,
                 1)

      RETURN
  END  

If you are sending anything other than simple strings I would recommend using a POST with an appropriate request body, or passing the entire list as an appropriately encoded JSON string. However, with simple strings you just need to append each value to the request URL appropriately and Jersey will deserialize it for you. So given the following example endpoint:

@Path("/service/echo") public class MyServiceImpl {
    public MyServiceImpl() {
        super();
    }

    @GET
    @Path("/withlist")
    @Produces(MediaType.TEXT_PLAIN)
    public Response echoInputList(@QueryParam("list") final List<String> inputList) {
        return Response.ok(inputList).build();
    }
}

Your client would send a request corresponding to:

GET http://example.com/services/echo?list=Hello&list=Stay&list=Goodbye

Which would result in inputList being deserialized to contain the values 'Hello', 'Stay' and 'Goodbye'

This works like magic, use it in the CSS file on the div you want to have on the new line:

.div_class {
    clear: left;
}

Or declare it in the html:

<div style="clear: left">
     <!-- Content... -->
</div>

http://en.wikibooks.org/wiki/LaTeX/Tables#Resize_tables talks about two ways to do this.

I used:

\scalebox{0.7}{
  \begin{tabular}
    ...
  \end{tabular}
}

There's no easy way (in terms of performance) to do what you want to do.

Reflection works with assemblys and types mainly so you'll have to get all the types of the assembly and query them for the right interface. Here's an example:

Assembly asm = Assembly.Load("MyAssembly");
Type[] types = asm.GetTypes();
Type[] result = types.where(x => x.GetInterface("IMyInterface") != null);

That will get you all the types that implement the IMyInterface in the Assembly MyAssembly

It looks like you're willing to strip fractions of a second... the problem is you can't use '00' as the hour with %I

>>> time.strptime('00:00:00,000'.split(',')[0],'%H:%M:%S')
time.struct_time(tm_year=1900, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=0, tm_yday=1, tm_isdst=-1)
>>>

I ran into the same problem and found that the documentation has example for this type of scenario (where we write STDERR TO STDOUT and always exit successfully with return code 0) without causing/catching an exception.

output = subprocess.check_output("ping -c 2 -W 2 1.1.1.1; exit 0", stderr=subprocess.STDOUT, shell=True)

Now, you can use standard string function find to check the output string output.

import("time")

layout := "2006-01-02T15:04:05.000Z"
str := "2014-11-12T11:45:26.371Z"
t, err := time.Parse(layout, str)
if err != nil {
    fmt.Println(err)
}
fmt.Println(t)

gives:

>> 2014-11-12 11:45:26.371 +0000 UTC

The same answer as @Richard W but for Windows (PowerShell)

git tag | foreach-object -process { git tag -d $_ }
git fetch -t

Do it like this: Remember to close iframe tag.

<iframe src="http://samplepdf.com/sample.pdf" width="800" height="600"></iframe>

I tried every answer but without success. The following solution helped me. If you don't have write access on the repository or getting a fatal 403 error, you can solve this easily by forking the cloned project, creating a new branch and pushing that branch to your repository. You will be able to make a pull request on the cloned project and let the person that has the write permission to do the merge.

You could do this in one of three ways:

1. Use single and double quotes together:

    print('"A word that needs quotation marks"')
    "A word that needs quotation marks"

2. Escape the double quotes within the string:

    print("\"A word that needs quotation marks\"")
    "A word that needs quotation marks" 

3. Use triple-quoted strings:

    print(""" "A word that needs quotation marks" """)
    "A word that needs quotation marks" 

BehaviorSubject keeps in memory the last value that was emitted by the observable. A regular Subject doesn't.

BehaviorSubject is like ReplaySubject with a buffer size of 1.

There is an example how to achieve it, when the card is at the very bottom of the screen. If someone has this kind of problem just do something like that:

<android.support.v7.widget.CardView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="-5dp"
    card_view:cardCornerRadius="4dp">

    <SomeView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="5dp">

    </SomeView>

</android.support.v7.widget.CardView>

Card View has a negative bottom margin. The view inside a Card View has the same, but positive bottom margin. This way rounded parts are hidden below the screen, but everything looks exactly the same, because the inner view has a counter margin.

There should be one - and preferably only one - obvious way to do it.

Therefore list(dictionary.values()) is the one way.

Yet, considering Python3, what is quicker?

[*L] vs. [].extend(L) vs. list(L)

small_ds = {x: str(x+42) for x in range(10)}
small_df = {x: float(x+42) for x in range(10)}

print('Small Dict(str)')
%timeit [*small_ds.values()]
%timeit [].extend(small_ds.values())
%timeit list(small_ds.values())

print('Small Dict(float)')
%timeit [*small_df.values()]
%timeit [].extend(small_df.values())
%timeit list(small_df.values())

big_ds = {x: str(x+42) for x in range(1000000)}
big_df = {x: float(x+42) for x in range(1000000)}

print('Big Dict(str)')
%timeit [*big_ds.values()]
%timeit [].extend(big_ds.values())
%timeit list(big_ds.values())

print('Big Dict(float)')

%timeit list(big_df.values())

1. For small dictionaries * operator is quicker
2. For big dictionaries where it matters list() is maybe slightly quicker

use #include "ClasseAusiliaria.c" [Dont use angle brackets (< >) ]

and I prefer save file with .h extension in the same Directory/folder.

#include "ClasseAusiliaria.h"

Try this

<input type="button" onClick="return click();">button text</input>  

You can do this, I am using

DataTable 1.10.5

using this code:

var versionNo = $.fn.dataTable.version;
alert(versionNo);

This is how I insert new record on my DataTable using row.add (My table has 10 columns), which can also includes HTML tag elements:

function fncInsertNew() {
            var table = $('#tblRecord').DataTable();

            table.row.add([
                    "Tiger Nixon",
                    "System Architect",
                    "$3,120",
                    "2011/04/25",
                    "Edinburgh",
                    "5421",
                    "Tiger Nixon",
                    "System Architect",
                    "$3,120",
                    "<p>Hello</p>"
            ]).draw();
        }

For multiple inserts at the same time, use rows.add instead:

var table = $('#tblRecord').DataTable();

table.rows.add( [ {
        "Tiger Nixon",
        "System Architect",
        "$3,120",
        "2011/04/25",
        "Edinburgh",
        "5421"
    }, {
        "Garrett Winters",
        "Director",
        "$5,300",
        "2011/07/25",
        "Edinburgh",
        "8422"
    }]).draw();

1. You should not be updating 10k rows in a set unless you are certain that the operation is getting Page Locks (due to multiple rows per page being part of the UPDATE operation). The issue is that Lock Escalation (from either Row or Page to Table locks) occurs at 5000 locks. So it is safest to keep it just below 5000, just in case the operation is using Row Locks.

2. You should not be using SET ROWCOUNT to limit the number of rows that will be modified. There are two issues here:

   1. It has that been deprecated since SQL Server 2005 was released (11 years ago):

      Using SET ROWCOUNT will not affect DELETE, INSERT, and UPDATE statements in a future release of SQL Server. Avoid using SET ROWCOUNT with DELETE, INSERT, and UPDATE statements in new development work, and plan to modify applications that currently use it. For a similar behavior, use the TOP syntax

   2. It can affect more than just the statement you are dealing with:

      Setting the SET ROWCOUNT option causes most Transact-SQL statements to stop processing when they have been affected by the specified number of rows. This includes triggers. The ROWCOUNT option does not affect dynamic cursors, but it does limit the rowset of keyset and insensitive cursors. This option should be used with caution.

   Instead, use the TOP () clause.

3. There is no purpose in having an explicit transaction here. It complicates the code and you have no handling for a ROLLBACK, which isn't even needed since each statement is its own transaction (i.e. auto-commit).

4. Assuming you find a reason to keep the explicit transaction, then you do not have a TRY / CATCH structure. Please see my answer on DBA.StackExchange for a TRY / CATCH template that handles transactions:

   Are we required to handle Transaction in C# Code as well as in Store procedure

I suspect that the real WHERE clause is not being shown in the example code in the Question, so simply relying upon what has been shown, a better model would be:

DECLARE @Rows INT,
        @BatchSize INT; -- keep below 5000 to be safe

SET @BatchSize = 2000;

SET @Rows = @BatchSize; -- initialize just to enter the loop

BEGIN TRY    
  WHILE (@Rows = @BatchSize)
  BEGIN
      UPDATE TOP (@BatchSize) tab
      SET    tab.Value = 'abc1'
      FROM  TableName tab
      WHERE tab.Parameter1 = 'abc'
      AND   tab.Parameter2 = 123
      AND   tab.Value <> 'abc1' COLLATE Latin1_General_100_BIN2;
      -- Use a binary Collation (ending in _BIN2, not _BIN) to make sure
      -- that you don't skip differences that compare the same due to
      -- insensitivity of case, accent, etc, or linguistic equivalence.

      SET @Rows = @@ROWCOUNT;
  END;
END TRY
BEGIN CATCH
  RAISERROR(stuff);
  RETURN;
END CATCH;

By testing @Rows against @BatchSize, you can avoid that final UPDATE query (in most cases) because the final set is typically some number of rows less than @BatchSize, in which case we know that there are no more to process (which is what you see in the output shown in your answer). Only in those cases where the final set of rows is equal to @BatchSize will this code run a final UPDATE affecting 0 rows.

I also added a condition to the WHERE clause to prevent rows that have already been updated from being updated again.

For Bash/Python, here is a basic wrapper around python's simplejson:

json_parser() {
    local jsonfile="my_json_file.json"
    local tc="import simplejson,sys; myjsonstr=sys.stdin.read(); "`
            `"myjson=simplejson.loads(myjsonstr);"
    # Build python print command based on $@
    local printcmd="print myjson"
    for (( argn=1; argn<=$#; argn++ )); do
        printcmd="$printcmd['${!argn}']"
    done
    local result=$(python -c "$tc $printcmd.keys()" <$jsonfile 2>/dev/null \
        || python -c "$tc $printcmd" <$jsonfile 2>/dev/null)
    # For returning space-separated values
    echo $result|sed -e "s/[]|[|,|']//g"
    #echo $result 
}

It really only handles the nested-dictionary style of data, but it works for what I needed, and is useful for walking through the json. It could probably be adapted to taste.

Anyway, something homegrown for those not wanting to source in yet another external dependency. Except for python, of course.

Ex. json_parser {field1} {field2} would run print myjson['{field1}']['{field2}'], yielding either the keys or the values associated with {field2}, space-separated.

ViewBag is server side code.
Javascript is client side code.

You can't really connect them.

You can do something like this:

var x = $('#' + '@(ViewBag.CC)').val();

But it will get parsed on the server, so you didn't really connect them.

Use ssh for that purpose. Generate keys without using a password and place it to .authorized_keys at the remote machine. Create the script to be run remotely, copy it to the other machine and then just run it remotely using ssh.

I used this approach many times with a big success. Also note that it is much more secure than telnet.

lonesomeday's answer is absolutely correct, I just thought I would add this tidbit. I had made a method a while back for getting browser in Vanilla JS and eventually curved it to replace jQuery.browser in later versions of jQuery. It does not interfere with any part of the new jQuery lib, but provides the same functionality of the traditional jQuery.browser object, as well as some other little features.

New Extended Version!

Is much more thorough for newer browser. Also, 90+% accuracy on mobile testing! I won't say 100%, as I haven't tested on every mobile browser, but new feature adds $.browser.mobile boolean/string. It's false if not mobile, else it will be a String name for the mobile device or browser (Best Guesss like: Android, RIM Tablet, iPod, etc...).

One possible caveat, may not work with some older (unsupported) browsers as it is completely reliant on userAgent string.

Given the right programmer, Assembler programs can always be made faster than their C counterparts (at least marginally). It would be difficult to create a C program where you couldn't take out at least one instruction of the Assembler.

The alert() wants to display a string, so it will interpret "2">"10" as a string.

Use the following:

var greater = parseInt("2") > parseInt("10");
alert("Is greater than? " + greater);

var less = parseInt("2") < parseInt("10");
alert("Is less than? " + less);
