For those of you who, like me, come to this issue from Django, you should know that the docs provide a solution: https://docs.djangoproject.com/en/1.10/ref/models/fields/#foreignkey

"...To refer to models defined in another application, you can explicitly specify a model with the full application label. For example, if the Manufacturer model above is defined in another application called production, you’d need to use:

class Car(models.Model):
    manufacturer = models.ForeignKey(
        'production.Manufacturer',
        on_delete=models.CASCADE,
)

This sort of reference can be useful when resolving circular import dependencies between two applications...."

I know its too longtime to reply but just as an information purpose for future readers:

WebRequest

System.Object
    System.MarshalByRefObject
        System.Net.WebRequest

The WebRequest is an abstract base class. So you actually don't use it directly. You use it through it derived classes - HttpWebRequest and FileWebRequest.

You use Create method of WebRequest to create an instance of WebRequest. GetResponseStream returns data stream.

There are also FileWebRequest and FtpWebRequest classes that inherit from WebRequest. Normally, you would use WebRequest to, well, make a request and convert the return to either HttpWebRequest, FileWebRequest or FtpWebRequest, depend on your request. Below is an example:

Example:

var _request = (HttpWebRequest)WebRequest.Create("http://stackverflow.com");
var _response = (HttpWebResponse)_request.GetResponse();

WebClient

System.Object
        System.MarshalByRefObject
            System.ComponentModel.Component
                System.Net.WebClient

WebClient provides common operations to sending and receiving data from a resource identified by a URI. Simply, it’s a higher-level abstraction of HttpWebRequest. This ‘common operations’ is what differentiate WebClient from HttpWebRequest, as also shown in the sample below:

Example:

var _client = new WebClient();
var _stackContent = _client.DownloadString("http://stackverflow.com");

There are also DownloadData and DownloadFile operations under WebClient instance. These common operations also simplify code of what we would normally do with HttpWebRequest. Using HttpWebRequest, we have to get the response of our request, instantiate StreamReader to read the response and finally, convert the result to whatever type we expect. With WebClient, we just simply call DownloadData, DownloadFile or DownloadString.

However, keep in mind that WebClient.DownloadString doesn’t consider the encoding of the resource you requesting. So, you would probably end up receiving weird characters if you don’t specify and encoding.

NOTE: Basically "WebClient takes few lines of code as compared to Webrequest"

Differences between IEnumerable and IEnumerator :

• IEnumerable uses IEnumerator internally.
• IEnumerable doesn't know which item/object is executing.
• Whenever we pass IEnumerator to another function, it knows the current position of item/object.

• Whenever we pass an IEnumerable collection to another function, it doesn't know the current position of item/object (doesn't know which item its executing)

  IEnumerable have one method GetEnumerator()

public interface IEnumerable<out T> : IEnumerable
{
    IEnumerator<T> GetEnumerator();
}

IEnumerator has one property called Current and two methods, Reset() and MoveNext() (which is useful for knowing the current position of an item in a list).

public interface IEnumerator
{
     object Current { get; }
     bool MoveNext();
     void Reset();
}

This is what I found as I was plotting only 3 cells from each 4 columns lumped together. My chart has a merged cell with the date which is my x axis. The problem: BC26-BE27 are plotting as ZERO on my chart. enter image description here

I click on the filter on the side of the chart and found where it is showing all the columns for which the data points are charted. I unchecked the boxes that do not have values. enter image description here

It worked for me.

If you are debugging or similar - In chrome developer tools, you can simply use

$x('/html/.//div[@id="text"]')

If you wish to create a pdf from php, pdflib will help you (as some others suggested).

Else, if you want to convert an HTML page to PDF via PHP, you'll find a little trouble outta here.. For 3 years I've been trying to do it as best as I can.

So, the options I know are:

DOMPDF : php class that wraps the html and builds the pdf. Works good, customizable (if you know php), based on pdflib, if I remember right it takes even some CSS. Bad news: slow when the html is big or complex.

HTML2PS: same as DOMPDF, but this one converts first to a .ps (ghostscript) file, then, to whatever format you need (pdf, jpg, png). For me is little better than dompdf, but has the same speed problem.. but, better compatibility with CSS.

Those two are php classes, but if you can install some software on the server, and access it throught passthru() or system(), give a look to these too:

wkhtmltopdf: based on webkit (safari's wrapper), is really fast and powerful.. seems like this is the best one (atm) for converting html pages to pdf on the fly; taking only 2 seconds for a 3 page xHTML document with CSS2. It is a recent project, anyway, the google.code page is often updated.

htmldoc : This one is a tank, it never really stops/crashes.. the project looks dead since 2007, but anyway if you don't need CSS compatibility this can be nice for you.

If you are using impdp command example from @sathyajith-bhat response:

impdp <username>/<password> directory=<directoryname> dumpfile=<filename>.dmp logfile=<filename>.log full=y;

you will need to use mandatory parameter directory and create and grant it as:

CREATE OR REPLACE DIRECTORY DMP_DIR AS 'c:\Users\USER\Downloads';
GRANT READ, WRITE ON DIRECTORY DMP_DIR TO {USER};

or use one of defined:

select * from DBA_DIRECTORIES;

My ORACLE Express 11g R2 has default named DATA_PUMP_DIR (located at {inst_dir}\app\oracle/admin/xe/dpdump/) you sill need to grant it for your user.

From Docker 17.06 onwards, a special Mac-only DNS name is available in docker containers that resolves to the IP address of the host. It is:

docker.for.mac.localhost

The documentation is here: https://docs.docker.com/docker-for-mac/networking/#httphttps-proxy-support

No, that's the standard way to do it. It shouldn't cause errors.

I can't comment on how efficient this is, but here's a solution:

applyToGivenRow = @(func, matrix) @(row) func(matrix(row, :))
applyToRows = @(func, matrix) arrayfun(applyToGivenRow(func, matrix), 1:size(matrix,1))'

% Example
myMx = [1 2 3; 4 5 6; 7 8 9];
myFunc = @sum;

applyToRows(myFunc, myMx)

I'm a few years late, but why not this?

[Tt][Ee][Ss][Tt]

A small note about the efficiency of abovementioned methods:

 library(microbenchmark)

  microbenchmark(
    which("Feb" == month.abb)[[1]],
    which(month.abb %in% "Feb"))

  Unit: nanoseconds
   min     lq    mean median     uq  max neval
   891  979.0 1098.00   1031 1135.5 3693   100
   1052 1175.5 1339.74   1235 1390.0 7399  100

So, the best one is

    which("Feb" == month.abb)[[1]]

I had to include -lmysqlcppconn to my build in order to get it to work.

It's all a matter of style. It's useful for debugging but otherwise it shouldn't be used in the final version of the program. It really doesn't matter on the memory issue because I'm sure that those guys who invented the system("pause") were anticipating that it'd be used often. In another perspective, computers get throttled on their memory for everything else we use on the computer anyways and it doesn't pose a direct threat like dynamic memory allocation, so I'd recommend it for debugging code, but nothing else.

If you are using jQuery:

$('#sel').val('bike');

Below is an example that gets as close as you get.

for(var key in data){
  var value = data[key];    
  //your processing here
}

If you're using jQuery see: http://api.jquery.com/jQuery.each/

a solution can be having the close inside your modal

take a look at this simple example

Cursors may also be used, although it is inefficient. The following stackoverflow post discusses the usage of cursors :

INSERT and UPDATE a record using cursors in oracle

To get the index by value, simply add .index[0] to the end of a query. This will return the index of the first row of the result...

So, applied to your dataframe:

In [1]: a[a['c2'] == 1].index[0]     In [2]: a[a['c1'] > 7].index[0]   
Out[1]: 0                            Out[2]: 4                         

Where the query returns more than one row, the additional index results can be accessed by specifying the desired index, e.g. .index[n]

In [3]: a[a['c2'] >= 7].index[1]     In [4]: a[(a['c2'] > 1) & (a['c1'] < 8)].index[2]  
Out[3]: 4                            Out[4]: 3 

It can now be changed to lambda version

@Override
public void actionPerformed(ActionEvent e) {
    Platform.runLater(() -> {
        try {
            //an event with a button maybe
            System.out.println("button is clicked");
        } catch (IOException | COSVisitorException ex) {
            Exceptions.printStackTrace(ex);
        }
    });
}

By looking at www.npmjs.com/install.sh I found there is a way to install a specific version by setting an environment-variable

export npm_install="2.14.14"

Then run the download-script as described at npmjs.com:

curl -L https://www.npmjs.com/install.sh | sh

If you omit setting the npm_install variable, then it will install the the version they have marked as latest

Change ownership and permissions folder

sudo chown -R username.www-data /var/www

sudo chmod -R +rwx /var/www

A very common usecase of calc is take 100% width and adding some margin around the element.

One can do so with:

@someMarginVariable = 15px;

margin: @someMarginVariable;
width: calc(~"100% - "@someMarginVariable*2);
width: -moz-calc(~"100% - "@someMarginVariable*2);
width: -webkit-calc(~"100% - "@someMarginVariable*2);

Change file AndroidManifest.xml

<uses-sdk android:minSdkVersion="19"/>

<uses-sdk android:minSdkVersion="14"/>

I have written a complete article at Spring Boot JPA Multiple Data Sources Example. In this article, we will learn how to configure multiple data sources and connect to multiple databases in a typical Spring Boot web application. We will use Spring Boot 2.0.5, JPA, Hibernate 5, Thymeleaf and H2 database to build a simple Spring Boot multiple data sources web application.

You don't set a timeout for the socket, you set a timeout for the operations you perform on that socket.

For example socket.connect(otherAddress, timeout)

Or socket.setSoTimeout(timeout) for setting a timeout on read() operations.

See: http://docs.oracle.com/javase/7/docs/api/java/net/Socket.html

The html

<select id="drop"  name="company" class="company btn btn-outline   dropdown-toggle" >
   <option value="demo1">Group Medical</option>
   <option value="demo">Motor Insurance</option>
</select>

Script.js

$("#drop").change(function () {                            
   var category= $('select[name=company]').val() // Here we can get the value of selected item
   alert(category); 
});

The solution of creating a new HTML file with HTML (Web Forms) Designer worked for that file but not for other, individual HTML files that I wanted to edit.

I did find the Open With option in the Open File dialogue and was able to select the HTML (Web Forms) Editor there. Having clicked the "Set as Default" option in that window, VS then remembered to use that editor when I opened other HTML files.

Use Fail module.

1. Use ignore_errors with every task that you need to ignore in case of errors.
2. Set a flag (say, result = false) whenever there is a failure in any task execution
3. At the end of the playbook, check if flag is set, and depending on that, fail the execution

- fail: msg="The execution has failed because of errors."
  when: flag == "failed"

Update:

Use register to store the result of a task like you have shown in your example. Then, use a task like this:

- name: Set flag
  set_fact: flag = failed
  when: "'FAILED' in command_result.stderr"

You can get the channel ID with the username (in your case "klauskkpm") using the filter "forUsername", like this:

I was having the same problem with 3 of 4 inline svgs I was using, and they only disappeared (in one case, partially) on IE11.

I had <meta http-equiv="x-ua-compatible" content="ie=edge"> on the page.

In the end, the problem was extra clipping paths on the svg file. I opened the files on Illustrator, removed the clipping path (normally at the bottom of the layers) and now they're all working.

svn log -q -v shows paths and hides comments. All the paths are indented so you can search for lines starting with whitespace. Then pipe to cut and sort to tidy up:

svn log --stop-on-copy -q -v | grep '^[[:space:]]'| cut -c6- | sort -u

This gets all the paths mentioned on the branch since its branch point. Note it will list deleted and added, as well as modified files. I just used this to get the stuff I should worry about reviewing on a slightly messy branch from a new dev.

I already showed this elsewhere on SO (How to use a variable in the format specifier statement? , not an exact duplicate IMHO), but I think it is worthwhile to place it here. It is possible to use the techniques from other answers for this question to make a simple function

function itoa(i) result(res)
  character(:),allocatable :: res
  integer,intent(in) :: i
  character(range(i)+2) :: tmp
  write(tmp,'(i0)') i
  res = trim(tmp)
end function

which you can use after without worrying about trimming and left-adjusting and without writing to a temporary variable:

OPEN(1, FILE = 'Output'//itoa(i)//'.TXT')

It requires Fortran 2003 because of the allocatable string.

In my case, the correct menu path was:

File > Default settings > Project Interpreter

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

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

if you are looking to change the colour of the cell in case of vlookup error then go for conditional formatting . To do this go the "CONDITIONAL FORMATTING" > "NEW RULE". In this choose the "Select the rule type" = "Format only cells that contains" . After this the window below changes , in which choose "Error" in the first drop-down .After this proceed accordingly.

Say you have a branch master with the following commit history:

A -- B -- C -- D

Now, you create a branch test, work on it, and do 4 commits:

                 E -- F -- G -- H
                /
A -- B -- C -- D

master's head points to D, and test's head points to H.

The "Already up-to-date" message shows up when the HEAD of the branch you are merging into is a parent of the chain of commits of the branch you want to merge. That's the case, here: D is a parent of E.

There is nothing to merge from test to master, since nothing has changed on master since then. What you want to do here is literally to tell Git to have master's head to point to H, so master's branch has the following commits history:

A -- B -- C -- D -- E -- F -- G -- H

This is a job for Git command reset. You also want the working directory to reflect this change, so you'll do a hard reset:

git reset --hard H

Using Excel 2010 ? Try

Do not use @@fetch_status - this will return status from the last cursor in the current connection. Use the example below:

declare @sqCur cursor;
declare @data varchar(1000);
declare @i int = 0, @lastNum int, @rowNum int;
set @sqCur = cursor local static read_only for 
    select
         row_number() over (order by(select null)) as RowNum
        ,Data -- you fields
    from YourIntTable
open @cur
begin try
    fetch last from @cur into @lastNum, @data
    fetch absolute 1 from @cur into @rowNum, @data --start from the beginning and get first value 
    while @i < @lastNum
    begin
        set @i += 1

        --Do your job here
        print @data

        fetch next from @cur into @rowNum, @data
    end
end try
begin catch
    close @cur      --|
    deallocate @cur --|-remove this 3 lines if you do not throw
    ;throw          --|
end catch
close @cur
deallocate @cur

The clientside-require library provides an asynchronous load() function that can be used to load any JS file or NPM module (which uses module.exports), any .css file, any .json, any .html, any any other file as text.

e.g., npm install clientside-require --save

<script src = '/node_modules/clientside-require/dist/bundle.js'></script>
<script>
load('color-name') // an npm module
   .then(color_name=>{
        console.log(color_name.blue); // outputs  [0, 0, 255]
   })
</script>

A really cool part of this project is that inside of any load()ed script, you can use the synchronous require() function the same way you would expect in node.js!

e.g.,

load('/path/to/functionality.js')

and inside /path/to/functionality.js:

var query_string = require("qs") // an npm module
module.exports = function(name){
    return qs.stringify({
         name:name,
         time:new Date()
    }
}

That last part, implementing the synchronous require() method, is what enables it to utilize NPM packages built to run on the server.

This module was designed to implement the require functionality as closely as possible in the browser. Disclaimer: I have written this module.

If you want to clean your database named "example_db":

1) Login to another db(for example 'postgres'):

psql postgres

2) Remove your database:

DROP DATABASE example_db;

3) Recreate your database:

CREATE DATABASE example_db;

For immutable data types:

l = [0] * 100
# [0, 0, 0, 0, 0, ...]

l = ['foo'] * 100
# ['foo', 'foo', 'foo', 'foo', ...]

For values that are stored by reference and you may wish to modify later (like sub-lists, or dicts):

l = [{} for x in range(100)]

(The reason why the first method is only a good idea for constant values, like ints or strings, is because only a shallow copy is does when using the <list>*<number> syntax, and thus if you did something like [{}]*100, you'd end up with 100 references to the same dictionary - so changing one of them would change them all. Since ints and strings are immutable, this isn't a problem for them.)

If you want to add to an existing list, you can use the extend() method of that list (in conjunction with the generation of a list of things to add via the above techniques):

a = [1,2,3]
b = [4,5,6]
a.extend(b)
# a is now [1,2,3,4,5,6]

CORRECTION: I found out that the above solution is terrible. Especially when your phone is slow. And here, I found another solution: calculate out the px value of the element, including the margins and paddings: dp to px: https://stackoverflow.com/a/6327095/1982712

or dimens.xml to px: https://stackoverflow.com/a/16276351/1982712

sp to px: https://stackoverflow.com/a/9219417/1982712 (reverse the solution)

or dimens to px: https://stackoverflow.com/a/16276351/1982712

and that's it.

There are two main differences.

Accessing the association sides

The first one is related to how you will access the relationship. For a unidirectional association, you can navigate the association from one end only.

So, for a unidirectional @ManyToOne association, it means you can only access the relationship from the child side where the foreign key resides.

If you have a unidirectional @OneToMany association, it means you can only access the relationship from the parent side which manages the foreign key.

For the bidirectional @OneToMany association, you can navigate the association in both ways, either from the parent or from the child side.

You also need to use add/remove utility methods for bidirectional associations to make sure that both sides are properly synchronized.

Performance

The second aspect is related to performance.

1. For @OneToMany, unidirectional associations don't perform as well as bidirectional ones.
2. For @OneToOne, a bidirectional association will cause the parent to be fetched eagerly if Hibernate cannot tell whether the Proxy should be assigned or a null value.
3. For @ManyToMany, the collection type makes quite a difference as Sets perform better than Lists.

Actually, For me below works fine.

@Component
public class MyBean {

   public static String prop;

   @Value("${some.prop}")
   public void setProp(String prop) {
      this.prop= prop;
   }

   public MyBean() {

   }

   @PostConstruct
   public void init() {
      System.out.println("================== " + prop + "================== ");
   }

}

Now whereever i want, just invoke

MyBean.prop

it will return value.

First uninstall python and again install the latest version during installation use custom install and mark all user checkbox and set the installation path C:\Python 3.9 and make PYTHON_HOME value C:\Python 3.9 in the Environmental variable it works for me

.button{
    background-image:url('/image/btn.png');
    background-repeat:no-repeat;
}

It should be like that

public static void main(String[] args) {
        EchoServer0 e = new EchoServer0();
        // TODO Auto-generated method stub
        e.listen();
}

Your variable of type Object truly doesn't have such a method, but the type EchoServer0 you define above certainly has.

I believe that this is known as "interned" strings. Python does this, so does Java, and so do C and C++ when compiling in optimized modes.

If you use two identical strings, instead of wasting memory by creating two string objects, all interned strings with the same contents point to the same memory.

This results in the Python "is" operator returning True because two strings with the same contents are pointing at the same string object. This will also happen in Java and in C.

This is only useful for memory savings though. You cannot rely on it to test for string equality, because the various interpreters and compilers and JIT engines cannot always do it.

I've added some more to the above functions, to check strings like, "Go hang a salami, I'm a lasagna hog".

function checkPalindrom(str) {
    var str = str.replace(/[^a-zA-Z0-9]+/gi, '').toLowerCase();
    return str == str.split('').reverse().join('');
}

Thanks

You can change the way Safari opens a new page in Safari > Preferences > Tabs > 'Open pages in tabs instead of windows' > 'Automatically'

To grant a permission:

grant select on schema_name.sequence_name to user_or_role_name;

To check which permissions have been granted

select * from all_tab_privs where TABLE_NAME = 'sequence_name'

You can use sed for this too -

sed -n '320123'p filename 

This will print line number 320123.

If you want a range then you can do -

sed -n '320123,320150'p filename 

If you want from a particular line to the very end then -

sed -n '320123,$'p filename 

If SET time_zone or SET GLOBAL time_zone does not work, you can change as below:

• Change timezone system, example: ubuntu... $ sudo dpkg-reconfigure tzdata

• Restart the server or you can restart apache2 and mysql (/etc/init.d/mysql restart)

Another option

min.getTime() <= d.getTime() && d.getTime() <= max.getTime()

Another way to pass named parameters to Bash... is passing by reference. This is supported as of Bash 4.0

#!/bin/bash
function myBackupFunction(){ # directory options destination filename
local directory="$1" options="$2" destination="$3" filename="$4";
  echo "tar cz ${!options} ${!directory} | ssh root@backupserver \"cat > /mnt/${!destination}/${!filename}.tgz\"";
}

declare -A backup=([directory]=".." [options]="..." [destination]="backups" [filename]="backup" );

myBackupFunction backup[directory] backup[options] backup[destination] backup[filename];

An alternative syntax for Bash 4.3 is using a nameref.

Although the nameref is a lot more convenient in that it seamlessly dereferences, some older supported distros still ship an older version, so I won't recommend it quite yet.

Try adding animation-fill-mode: forwards;. For example like this:

-webkit-animation: bubble 1.0s forwards; /* for less modern browsers */
        animation: bubble 1.0s forwards;

If you keep track of the tail node, you don't need to loop through every element in the list.

Just update the tail to point to the new node:

AddValueToListEnd(value) {
    var node = new Node(value);

    if(!this.head) {
        this.head = node;
        this.tail = node;
    } else {
        this.tail.next = node; //point old tail to new node
    }
        
    this.tail = node; //now set the new node as the new tail
}

In plain English:

• Create a new node with the given value
• If the list is empty, point head and tail to the new node
• If the list is not empty, set the old tail.next to be the new node
• In either case, update the tail pointer to be the new node

x is used to print t pointer argument in hexadecimal.

A typical address when printed using %x would look like bfffc6e4 and the sane address printed using %p would be 0xbfffc6e4

Modifying the location of window might cause some issue especially when you have a persistent connection like websocket. So I always resort to good old iframe solution.

HTML

<input type="button" onclick="downloadButtonClicked()" value="Download"/>
...
...
...
<iframe style="display:none;" name="hiddenIframe" id="hiddenIframe"></iframe>

Javascript

function downloadButtonClicked() {
    // Simulate a link click
    var url = 'your_download_url_here';
    var elem = document.createElement('a');
    elem.href = url;
    elem.target = 'hiddenIframe';
    elem.click();
}

There may be a better solution, but this is what came to mind:

var value = $("#yourInput").val();
$("#yourInput").on('keyup change click', function () {
    if(this.value !== value) {
        value = this.value;
        //Do stuff
    }        
});

Here's a working example.

It simply binds an event handler to the keyup, change and click events. It checks whether or not the value has changed, and if so, stores the current value so it can check again next time. The check is required to deal with the click event.

You're accessing the latitude and longitude incorrectly.

Try

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">

var geocoder = new google.maps.Geocoder();
var address = "new york";

geocoder.geocode( { 'address': address}, function(results, status) {

  if (status == google.maps.GeocoderStatus.OK) {
    var latitude = results[0].geometry.location.lat();
    var longitude = results[0].geometry.location.lng();
    alert(latitude);
  } 
}); 
</script>

If you want to use a RecyclerView with the GridLayoutManager, this is the way to achieve horizontal scroll.

recyclerView.setLayoutManager(
new GridLayoutManager(recyclerView.getContext(), rows, GridLayoutManager.HORIZONTAL, false));

Use BigDecimal.valueOf(double d) instead of new BigDecimal(double d). The last one has precision errors by float and double.

A base R solution is to combine the output of aggregate() with a merge() step. I find the formula interface to aggregate() a little more useful than the standard interface, partly because the names on the output are nicer, so I'll use that:

The aggregate() step is

maxs <- aggregate(Score ~ Group, data = dat, FUN = max)

and the merge() step is simply

merge(maxs, dat)

This gives us the desired output:

R> maxs <- aggregate(Score ~ Group, data = dat, FUN = max)
R> merge(maxs, dat)
  Group Score Info
1     1     3    c
2     2     4    d

You could, of course, stick this into a one-liner (the intermediary step was more for exposition):

merge(aggregate(Score ~ Group, data = dat, FUN = max), dat)

The main reason I used the formula interface is that it returns a data frame with the correct names for the merge step; these are the names of the columns from the original data set dat. We need to have the output of aggregate() have the correct names so that merge() knows which columns in the original and aggregated data frames match.

The standard interface gives odd names, whichever way you call it:

R> aggregate(dat$Score, list(dat$Group), max)
  Group.1 x
1       1 3
2       2 4
R> with(dat, aggregate(Score, list(Group), max))
  Group.1 x
1       1 3
2       2 4

We can use merge() on those outputs, but we need to do more work telling R which columns match up.

For the truly lazy (no typing, only totally easy copy and paste):

sudo usermod -aG vboxsf $USER

Log out and back in to make the change active.

I know it's a "me too" solution, but I am truly lazy and didn't find any other solution to appeal my innate apathy... :)

For those of you who are interested in getting the value adding a custom column name, this worked for me:

CAST(
    CASE WHEN EXISTS ( 
           SELECT * 
           FROM mytable 
           WHERE mytable.id = 1
    ) 
    THEN TRUE 
    ELSE FALSE 
    END AS bool) 
AS "nameOfMyColumn"

You can skip the double quotes from the column name in case you're not interested in keeping the case sensitivity of the name (in some clients).

I slightly tweaked @Chad's answer for this.

I don't know why those commands are not working for you, but you can also try timeout

timeout <delay in seconds>

If you want to keep your bashrc simple, you can remove all the conda init generated clutter, and keep only a single line:

. "/Users/geoff/anaconda2/etc/profile.d/conda.sh"

See Recommended change to enable conda in your shell.

This will make the conda command available without activating the base environment.

If you want to use your bashrc on other systems where conda is not installed in the same path, you can keep the if/fi lines as well to avoid error messages, i.e.:

if [ -f "/Users/geoff/anaconda2/etc/profile.d/conda.sh" ]; then
    . "/Users/geoff/anaconda2/etc/profile.d/conda.sh"
fi

I think you can also think of alternative architectures. Sometimes something can be done in another way much more easier. If the producer of HTML file is you, then you can write an HTTP handler to create an Excel document on the server (which is much more easier than in JavaScript) and send a file to the client. If you receive that HTML file from somewhere (like an HTML version of a report), then you still can use a server side language like C# or PHP to create the Excel file still very easily. I mean, you may have other ways too. :)

In my case, the table's id column was not set as an Identity column.

Tests

On the Tests class we will add an @XmlRootElement annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData property differs from the default mapping we will use the @XmlElement annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted

package forum11221136;

import javax.xml.bind.annotation.*;

@XmlRootElement
public class Tests {

    TestData testData;

    @XmlElement(name="test-data")
    public TestData getTestData() {
        return testData;
    }

    public void setTestData(TestData testData) {
        this.testData = testData;
    }

}

TestData

On this class I used the @XmlType annotation to specify the order in which the elements should be ordered in. I added a testData property that appeared to be missing. I also used an @XmlElement annotation for the same reason as in the Tests class.

package forum11221136;

import java.util.List;
import javax.xml.bind.annotation.*;

@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
    String title;
    String book;
    String count;
    List<TestData> testData;

    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getBook() {
        return book;
    }
    public void setBook(String book) {
        this.book = book;
    }
    public String getCount() {
        return count;
    }
    public void setCount(String count) {
        this.count = count;
    }
    @XmlElement(name="test-data")
    public List<TestData> getTestData() {
        return testData;
    }
    public void setTestData(List<TestData> testData) {
        this.testData = testData;
    }
}

Demo

Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.

package forum11221136;

import java.io.File;
import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Tests.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/forum11221136/input.xml");
        Tests tests = (Tests) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(tests, System.out);
    }

}

re is powerful:

import re


def isprime(n):
    return re.compile(r'^1?$|^(11+)\1+$').match('1' * n) is None

print [x for x in range(100) if isprime(x)]

###########Output#############
[2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97]

It's not smart enough to realize it's still a "vector" in math terms.

Say rather that it's smart enough to recognize a difference in dimensionality. :-)

I think the simplest thing you can do is select that row positionally using iloc, which gives you a Series with the columns as the new index and the values as the values:

>>> df = pd.DataFrame([list(range(5))], columns=["a{}".format(i) for i in range(5)])
>>> df
   a0  a1  a2  a3  a4
0   0   1   2   3   4
>>> df.iloc[0]
a0    0
a1    1
a2    2
a3    3
a4    4
Name: 0, dtype: int64
>>> type(_)
<class 'pandas.core.series.Series'>

class Graph<E> {
    private List<Vertex<E>> vertices;

    private static class Vertex<E> {
        E elem;
        List<Vertex<E>> neighbors;
    }
}

TextPad will allow you to perform this operation.

example:

test this sentence

Find what: \([^ ]*\) \(.*\) Replace with: \U\1\E \2

the \U will cause all following chars to be upper

the \E will turn off the \U

the result will be:

TEST this sentence

If you want a Popup that closes automatically, you should look for Toasts. But if you want a dialog that the user has to close first before proceeding, you should look for a Dialog.

For both approaches it is possible to read a text file with the text you want to display. But you could also hardcode the text or use R.String to set the text.

1. In "Structure" tab of your table
2. Click on the pencil of the variable you want auto_increment
3. under "Extra" tab choose "auto_increment"
4. then go to "Operations" tab of your table
5. Under "Table options" -> auto_increment type -> 10000

Set the value to "" and the expiry date to yesterday (or any date in the past)

setcookie("hello", "", time()-3600);

Then the cookie will expire the next time the page loads.

Apart from the options already given in other answers, there's a current more active, recent and open-source project called pygubu.

This is the first description by the author taken from the github repository:

Pygubu is a RAD tool to enable quick & easy development of user interfaces for the python tkinter module.

The user interfaces designed are saved as XML, and by using the pygubu builder these can be loaded by applications dynamically as needed. Pygubu is inspired by Glade.

Pygubu hello world program is an introductory video explaining how to create a first project using Pygubu.

The following in an image of interface of the last version of pygubu designer on a OS X Yosemite 10.10.2:

I would definitely give it a try, and contribute to its development.

$this->db->where('accommodation BETWEEN '' . $sdate . '' AND '' . $edate . ''');

this is my solution

In config.inc.php in the top-level directory, set

$cfg['DefaultLang'] = 'en-utf-8'; // Language if no other language is recognized
// or
$cfg['Lang'] = 'en-utf-8'; // Force this language for all users

If Lang isn't set, you should be able to select the language in the initial welcome screen, and the language your browser prefers should be preselected there.

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

Note that if typing if ( exists $hash{ key } ) isn’t too much work for you (which I prefer to use since the matter of interest is really the presence of a key rather than the truthiness of its value), then you can use the short and sweet

@hash{@key} = ();

I had to go into my GitExtensions Remote Repositories as nothing here seemed to be working. There I saw that 2 branches had no remote repository configured. after adjusting it looks as follows

Notice branch noExternal3 still shows as not having a remote repository. Not sure what combo of bash commands would have found or adjusted that.

useEffect has its own state/lifecycle, it will not update until you pass a function in parameters or effect destroyed.

object and array spread or rest will not work inside useEffect.

React.useEffect(() => {
    console.log("effect");
    (async () => {
        try {
            let result = await fetch("/query/countries");
            const res = await result.json();
            let result1 = await fetch("/query/projects");
            const res1 = await result1.json();
            let result11 = await fetch("/query/regions");
            const res11 = await result11.json();
            setData({
                countries: res,
                projects: res1,
                regions: res11
            });
        } catch {}
    })(data)
}, [setData])
# or use this
useEffect(() => {
    (async () => {
        try {
            await Promise.all([
                fetch("/query/countries").then((response) => response.json()),
                fetch("/query/projects").then((response) => response.json()),
                fetch("/query/regions").then((response) => response.json())
            ]).then(([country, project, region]) => {
                // console.log(country, project, region);
                setData({
                    countries: country,
                    projects: project,
                    regions: region
                });
            })
        } catch {
            console.log("data fetch error")
        }
    })()
}, [setData]);

Maybe you can use matplotlib for this, you can also plot normal images with it. If you call show() the image pops up in a window. Take a look at this:

http://matplotlib.org/users/image_tutorial.html

I just found my own solution to this problem, or at least my problem.
I was using justify-content: space-around instead of justify-content: space-between;.

This way the end elements will stick to the top and bottom, and you could have custom margins if you wanted.

Wrap text in a span and use jquery width()

select * from mytable where mydate > now() - interval '1 year';

If you only care about the date and not the time, substitute current_date for now()

The + operator is the normal concatenation choice, and is probably the fastest way to concatenate strings.

The difference between + and << is that << changes the object on its left hand side, and + doesn't.

irb(main):001:0> s = 'a'
=> "a"
irb(main):002:0> s + 'b'
=> "ab"
irb(main):003:0> s
=> "a"
irb(main):004:0> s << 'b'
=> "ab"
irb(main):005:0> s
=> "ab"

I found a shorter solution that does exactly what I want https://github.com/http-party/node-http-proxy

After installing http-proxy

npm install http-proxy --save

Use it like below in your server/index/app.js

var proxyServer = require('http-route-proxy');
app.use('/api/BLABLA/', proxyServer.connect({
  to: 'other_domain.com:3000/BLABLA',
  https: true,
  route: ['/']
}));

I really have spent days looking everywhere to avoid this issue, tried plenty of solutions and none of them worked but this one.

Hope it is going to help someone else too :)

It really all comes down to how you want to handle output that the command might return and whether you want your PHP script to wait for the callee program to finish or not.

• exec executes a command and passes output to the caller (or returns it in an optional variable).

• passthru is similar to the exec() function in that it executes a command . This function should be used in place of exec() or system() when the output from the Unix command is binary data which needs to be passed directly back to the browser.

• system executes an external program and displays the output, but only the last line.

If you need to execute a command and have all the data from the command passed directly back without any interference, use the passthru() function.

this code disable the button with 'YOUR_BUTTON_LABEL'. you can replace name in contains(). to disable

$(".ui-dialog-buttonpane button:contains('YOUR_BUTTON_LABEL')").button("disable");

replace 'YOUR_BUTTON_LABEL' with your button's label. to enable

$(".ui-dialog-buttonpane button:contains('YOUR_BUTTON_LABEL')").button("enable");

Java SE is use for the desktop applications and simple core functions. Java EE is used for desktop, but also web development, networking, and advanced things.

You can bind the mouseenter and mouseleave events and jQuery will emulate those where they are not native.

$("div.system_box").on('mouseenter', function(){
    //enter
})
.on('mouseleave', function(){
    //leave
});

note: do not use hover as that is deprecated

The following solution seems more accurate to me than combine JavaScript with Razor. Check this out: https://github.com/brooklynDev/NGon

You can add almost any complex data to ViewBag.Ngon and access it in JavaScript

In the controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var person = new Person { FirstName = "John", LastName = "Doe", Age = 30 };
        ViewBag.NGon.Person = person;
        return View();
    }
}

In JavaScript:

<script type="text/javascript">
    $(function () {
        $("#button").click(function () {
            var person = ngon.Person;
            var div = $("#output");
            div.html('');
            div.append("FirstName: " + person.FirstName);
            div.append(", LastName: " + person.LastName);
            div.append(", Age: " + person.Age);
        });
    });
</script>

It's allows any plain old CLR objects (POCOs) that can be serialized using the default JavascriptSerializer.

The basic idea behing the XToOnes in Hibernate is that they are not lazy in most case.

One reason is that, when Hibernate have to decide to put a proxy (with the id) or a null,
it has to look into the other table anyway to join. The cost of accessing the other table in the database is significant, so it might as well fetch the data for that table at that moment (non-lazy behaviour), instead of fetching that in a later request that would require a second access to the same table.

Edited: for details, please refer to ChssPly76 's answer. This one is less accurate and detailed, it has nothing to offer. Thanks ChssPly76.

Since 1.4 this is now possible with the * operator. When given two objects, it will merge them recursively. For example,

jq -s '.[0] * .[1]' file1 file2

Important: Note the -s (--slurp) flag, which puts files in the same array.

Would get you:

{
  "value1": 200,
  "timestamp": 1382461861,
  "value": {
    "aaa": {
      "value1": "v1",
      "value2": "v2",
      "value3": "v3",
      "value4": 4
    },
    "bbb": {
      "value1": "v1",
      "value2": "v2",
      "value3": "v3"
    },
    "ccc": {
      "value1": "v1",
      "value2": "v2"
    },
    "ddd": {
      "value3": "v3",
      "value4": 4
    }
  },
  "status": 200
}

If you also want to get rid of the other keys (like your expected result), one way to do it is this:

jq -s '.[0] * .[1] | {value: .value}' file1 file2

Or the presumably somewhat more efficient (because it doesn't merge any other values):

jq -s '.[0].value * .[1].value | {value: .}' file1 file2

I know it's not exactly what you're asking, but, for replacing a comma with a newline, this works great:

tr , '\n' < file

Adding answer to show example of stripping multiple characters including \r using tr and using sed. And illustrating using hexdump.

In my case I had found that a command ending with awk print of the last item |awk '{print $2}' in the line included a carriage-return \r as well as quotes.

I used sed 's/["\n\r]//g' to strip both the carriage-return and quotes.

I could also have used tr -d '"\r\n'.

Interesting to note sed -z is needed if one wishes to remove \n line-feed chars.

$ COMMAND=$'\n"REBOOT"\r   \n'

$ echo "$COMMAND" |hexdump -C
00000000  0a 22 52 45 42 4f 4f 54  22 0d 20 20 20 0a 0a     |."REBOOT".   ..|

$ echo "$COMMAND" |tr -d '"\r\n' |hexdump -C
00000000  52 45 42 4f 4f 54 20 20  20                       |REBOOT   |

$ echo "$COMMAND" |sed 's/["\n\r]//g' |hexdump -C
00000000  0a 52 45 42 4f 4f 54 20  20 20 0a 0a              |.REBOOT   ..|

$ echo "$COMMAND" |sed -z 's/["\n\r]//g' |hexdump -C
00000000  52 45 42 4f 4f 54 20 20  20                       |REBOOT   |

And this is relevant: What are carriage return, linefeed, and form feed?

• CR == \r == 0x0d
• LF == \n == 0x0a

DateTime inherits its equals method from AbstractInstant. It is implemented as such

public boolean equals(Object readableInstant) {     // must be to fulfil ReadableInstant contract     if (this == readableInstant) {         return true;     }     if (readableInstant instanceof ReadableInstant == false) {         return false;     }     ReadableInstant otherInstant = (ReadableInstant) readableInstant;     return         getMillis() == otherInstant.getMillis() &&         FieldUtils.equals(getChronology(), otherInstant.getChronology()); } 

Notice the last line comparing chronology. It's possible your instances' chronologies are different.

If you are on LINUX follow the steps below:

• Go to the download https://gradle.org/ and download the latest zip file (currently 3.1 is the latest version)

• Extract the downloaded zip file into /opt/android-studio/gradle/.

• Open your project in Android Studio and hit Ctrl + Alt + S

• Search for Gradle in the Search bar of the setting window

• Select: (X) Use local gradle distribution and set Gradle home to /opt/andriod-studio/gradle/gradle.x.x (where x.x is the vesrion of the gradle zip file you just downloaded.). Then click on apply.

• Try to sync Gradle again if the sync has already failed.If not close your project and reopen your project.

  Hope this solves your problem.

You might not have write permissions to install a node module in the global location such as /usr/local/lib/node_modules, in which case run npm install -g package as root.

I know this is a really old thread but I maintain that:

The easiest and safest method to fix this is to delete your hidden ".svn" folder and check everything out again.

It fixes most problems when svn screws around should keep local changes (marked as "conflicted") when you check out the head revision again.

Here is a more compact version of Jaydeep's idea of showing one dialog after the other. I like this solution because it has no dependencies.

        Date value = new Date();
        final Calendar cal = Calendar.getInstance();
        cal.setTime(value);
        new DatePickerDialog(this,
            new DatePickerDialog.OnDateSetListener() {
                @Override public void onDateSet(DatePicker view, 
                        int y, int m, int d) {
                    cal.set(Calendar.YEAR, y);
                    cal.set(Calendar.MONTH, m);
                    cal.set(Calendar.DAY_OF_MONTH, d);

                    // now show the time picker
                    new TimePickerDialog(NoteEditor.this,
                        new TimePickerDialog.OnTimeSetListener() {
                            @Override public void onTimeSet(TimePicker view, 
                                    int h, int min) {
                                cal.set(Calendar.HOUR_OF_DAY, h);
                                cal.set(Calendar.MINUTE, min);
                                value = cal.getTime();
                            }
                        }, cal.get(Calendar.HOUR_OF_DAY), 
                            cal.get(Calendar.MINUTE), true).show();
                 }
            }, cal.get(Calendar.YEAR), cal.get(Calendar.MONTH),
            cal.get(Calendar.DAY_OF_MONTH)).show();

You've correctly diagnosed your problem, so good job. Once you call into your search code, the for loop just keeps right on going.

I'm a big fan of https://github.com/caolan/async, and it serves me well. Basically with it you'd end up with something like:

var async = require('async')
async.eachSeries(Object.keys(config), function (key, next){ 
  search(config[key].query, function(err, result) { // <----- I added an err here
    if (err) return next(err)  // <---- don't keep going if there was an error

    var json = JSON.stringify({
      "result": result
    });
    results[key] = {
      "result": result
    }
    next()    /* <---- critical piece.  This is how the forEach knows to continue to
                       the next loop.  Must be called inside search's callback so that
                       it doesn't loop prematurely.*/
  })
}, function(err) {
  console.log('iterating done');
}); 

I hope that helps!

ipv=raw_input("Enter an ip address")
a=ipv.split('.')
s=str(bin(int(a[0]))+bin(int(a[1]))+bin(int(a[2]))+bin(int(a[3])))
s=s.replace("0b",".")
m=re.search('\.[0,1]{1,8}\.[0,1]{1,8}\.[0,1]{1,8}\.[0,1]{1,8}$',s)
if m is not None:
    print "Valid sequence of input"
else :
    print "Invalid input sequence"

Just to keep it simple I have used this approach. Simple as in to explain how really ipv4 address is evaluated. Checking whether its a binary number is although not required. Hope you like this.

Put this code in your .htaccess file

RewriteEngine On
ErrorDocument 404 /404.php

where 404.php is the file name and placed at root. You can put full path over here.

you can use this for example

$array = json_decode($string,true)

but validate the Json before. You can validate from http://jsonviewer.stack.hu/

Here is one more example:

function sortObject(obj) {_x000D_
  var arr = [];_x000D_
  var prop;_x000D_
  for (prop in obj) {_x000D_
    if (obj.hasOwnProperty(prop)) {_x000D_
      arr.push({_x000D_
        'key': prop,_x000D_
        'value': obj[prop]_x000D_
      });_x000D_
    }_x000D_
  }_x000D_
  arr.sort(function(a, b) {_x000D_
    return a.value - b.value;_x000D_
  });_x000D_
  return arr; // returns array_x000D_
}_x000D_
var list = {_x000D_
  car: 300,_x000D_
  bike: 60,_x000D_
  motorbike: 200,_x000D_
  airplane: 1000,_x000D_
  helicopter: 400,_x000D_
  rocket: 8 * 60 * 60_x000D_
};_x000D_
var arr = sortObject(list);_x000D_
console.log(arr);

I know it's a very late answer but I'd like to share what I did as per this link:

I added the below code to the pom.xml:

                    <goals>
                        <goal>build-info</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

And this Advice Controller in order to get the version as model attribute:

       {
          String version = buildProperties.getVersion();
          return version;
       }
    }

Even if your data falls within your specified limits (e.g. c(0, 335)), adding a geom_jitter() statement could push some points outside those limits, producing the same error message.

library(ggplot2)

range(mtcars$hp)

# No jitter -- no error message
ggplot(mtcars, aes(mpg, hp)) + 
    geom_point() +
    scale_y_continuous(limits=c(0,335))


# Jitter is too large -- this generates the error message
ggplot(mtcars, aes(mpg, hp)) + 
    geom_point() +
    geom_jitter(position = position_jitter(w = 0.2, h = 0.2)) +
    scale_y_continuous(limits=c(0,335))
#> Warning: Removed 1 rows containing missing values (geom_point).

While it's not currently possible with the script tag, it is possible with an iframe if it's from the same domain.

<iframe
id="mySpecialId"
src="/my/link/to/some.json"
onload="(()=>{if(!window.jsonData){window.jsonData={}}try{window.jsonData[this.id]=JSON.parse(this.contentWindow.document.body.textContent.trim())}catch(e){console.warn(e)}this.remove();})();"
onerror="((err)=>console.warn(err))();"
style="display: none;"
></iframe>

To use the above, simply replace the id and src attribute with what you need. The id (which we'll assume in this situation is equal to mySpecialId) will be used to store the data in window.jsonData["mySpecialId"].

In other words, for every iframe that has an id and uses the onload script will have that data synchronously loaded into the window.jsonData object under the id specified.

I did this for fun and to show that it's "possible' but I do not recommend that it be used.

Here is an alternative that uses a callback instead.

<script>
    function someCallback(data){
        /** do something with data */
        console.log(data);

    }
    function jsonOnLoad(callback){
        const raw = this.contentWindow.document.body.textContent.trim();
        try {
          const data = JSON.parse(raw);
          /** do something with data */
          callback(data);
        }catch(e){
          console.warn(e.message);
        }
        this.remove();
    }
</script>
<!-- I frame with src pointing to json file on server, onload we apply "this" to have the iframe context, display none as we don't want to show the iframe -->
<iframe src="your/link/to/some.json" onload="jsonOnLoad.apply(this, someCallback)" style="display: none;"></iframe>

Tested in chrome and should work in firefox. Unsure about IE or Safari.

Go to dev.twitter.com and create an application. This will provide you with the credentials you need. Here is an implementation I've recently written with PHP and cURL.

<?php
    function buildBaseString($baseURI, $method, $params) {
        $r = array();
        ksort($params);
        foreach($params as $key=>$value){
            $r[] = "$key=" . rawurlencode($value);
        }
        return $method."&" . rawurlencode($baseURI) . '&' . rawurlencode(implode('&', $r));
    }

    function buildAuthorizationHeader($oauth) {
        $r = 'Authorization: OAuth ';
        $values = array();
        foreach($oauth as $key=>$value)
            $values[] = "$key=\"" . rawurlencode($value) . "\"";
        $r .= implode(', ', $values);
        return $r;
    }

    $url = "https://api.twitter.com/1.1/statuses/user_timeline.json";

    $oauth_access_token = "YOURVALUE";
    $oauth_access_token_secret = "YOURVALUE";
    $consumer_key = "YOURVALUE";
    $consumer_secret = "YOURVALUE";

    $oauth = array( 'oauth_consumer_key' => $consumer_key,
                    'oauth_nonce' => time(),
                    'oauth_signature_method' => 'HMAC-SHA1',
                    'oauth_token' => $oauth_access_token,
                    'oauth_timestamp' => time(),
                    'oauth_version' => '1.0');

    $base_info = buildBaseString($url, 'GET', $oauth);
    $composite_key = rawurlencode($consumer_secret) . '&' . rawurlencode($oauth_access_token_secret);
    $oauth_signature = base64_encode(hash_hmac('sha1', $base_info, $composite_key, true));
    $oauth['oauth_signature'] = $oauth_signature;

    // Make requests
    $header = array(buildAuthorizationHeader($oauth), 'Expect:');
    $options = array( CURLOPT_HTTPHEADER => $header,
                      //CURLOPT_POSTFIELDS => $postfields,
                      CURLOPT_HEADER => false,
                      CURLOPT_URL => $url,
                      CURLOPT_RETURNTRANSFER => true,
                      CURLOPT_SSL_VERIFYPEER => false);

    $feed = curl_init();
    curl_setopt_array($feed, $options);
    $json = curl_exec($feed);
    curl_close($feed);

    $twitter_data = json_decode($json);

//print it out
print_r ($twitter_data);

?>

This can be run from the command line:

$ php <name of PHP script>.php

i tried the last answer from Sandeep Kumar, and i found way more simple :

<option value="1" <c:if test="${item.key == 1}"> selected </c:if>>

I have done it by the following way

1. Start cmd
2. Go to the "C:\Program Files\MySQL\MySQL Server 5.6\bin"
3. type mysqld --install

Like the following image. See for more information.

Assume s = socket.socket() The server can be bound by following methods: Method 1:

host = socket.gethostname()
s.bind((host, port))

Method 2:

host = socket.gethostbyname("localhost")  #Note the extra letters "by"
s.bind((host, port))

Method 3:

host = socket.gethostbyname("192.168.1.48")
s.bind((host, port))

If you do not exactly use same method on the client side, you will get the error: socket.error errno 111 connection refused.

So, you have to use on the client side exactly same method to get the host, as you do on the server. For example, in case of client, you will correspondingly use following methods:

Method 1:

host = socket.gethostname() 
s.connect((host, port))

Method 2:

host = socket.gethostbyname("localhost") # Get local machine name
s.connect((host, port))

Method 3:

host = socket.gethostbyname("192.168.1.48") # Get local machine name
s.connect((host, port))

Hope that resolves the problem.

I have to call ko.applyBinding each time search button click, and filtered data is return from server, and in this case following work for me without using ko.cleanNode.

I experienced, if we replace foreach with template then it should work fine in case of collections/observableArray.

You may find this scenario useful.

<ul data-bind="template: { name: 'template', foreach: Events }"></ul>

<script id="template" type="text/html">
    <li><span data-bind="text: Name"></span></li>
</script>

Note: If you're using AngularJS, then in addition to changing the step value, you may have to set ng-model-options="{updateOn: 'blur change'}" on the html input.

The reason for this is in order to have the validators run less often, as they are preventing the user from entering a decimal point. This way, the user can type in a decimal point and the validators go into effect after the user blurs.

You can pass multiple arguments like this.

List<object> arguments = new List<object>();
arguments.Add("first");      //argument 1
arguments.Add(new Object()); //argument 2
// ...
arguments.Add(10);           //argument n

backgroundWorker.RunWorkerAsync(arguments);

private void worker_DoWork(object sender, DoWorkEventArgs e) 
{
  List<object> genericlist = e.Argument as List<object>;
  //extract your multiple arguments from 
  //this list and cast them and use them. 
}

You have two options here. You can either add the untracked files to your Git repository (as the warning message suggested), or you can add the files to your .gitignore file, if you want Git to ignore them.

To add the files use git add:

git add Optimization/language/languageUpdate.php
git add email_test.php

To ignore the files, add the following lines to your .gitignore:

/Optimization/language/languageUpdate.php
/email_test.php

Either option should allow the git pull to succeed afterwards.

Using a random 'name' attribute works for me.

I reset the name attribute when sending the form so you can still access it by name when the form is sent. (using the id attribute to store the name)

Missing images will either just display nothing, or display a [ ? ] style box when their source cannot be found. Instead you may want to replace that with a "missing image" graphic that you are sure exists so there is better visual feedback that something is wrong. Or, you might want to hide it entirely. This is possible, because images that a browser can't find fire off an "error" JavaScript event we can watch for.

    //Replace source
    $('img').error(function(){
            $(this).attr('src', 'missing.png');
    });

   //Or, hide them
   $("img").error(function(){
           $(this).hide();
   });

Additionally, you may wish to trigger some kind of Ajax action to send an email to a site admin when this occurs.

The problem is that you're putting .name class instead of nameclass

Quoting the Forms Page in the HTML manual:

Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content. For example, a BUTTON element that contains an image functions like and may resemble an INPUT element whose type is set to "image", but the BUTTON element type allows content.

Here is an extension method that overloads the AppendText method with a color parameter:

public static class RichTextBoxExtensions
{
    public static void AppendText(this RichTextBox box, string text, Color color)
    {
        box.SelectionStart = box.TextLength;
        box.SelectionLength = 0;

        box.SelectionColor = color;
        box.AppendText(text);
        box.SelectionColor = box.ForeColor;
    }
}

And this is how you would use it:

var userid = "USER0001";
var message = "Access denied";
var box = new RichTextBox
              {
                  Dock = DockStyle.Fill,
                  Font = new Font("Courier New", 10)
              };

box.AppendText("[" + DateTime.Now.ToShortTimeString() + "]", Color.Red);
box.AppendText(" ");
box.AppendText(userid, Color.Green);
box.AppendText(": ");
box.AppendText(message, Color.Blue);
box.AppendText(Environment.NewLine);

new Form {Controls = {box}}.ShowDialog();

Note that you may notice some flickering if you're outputting a lot of messages. See this C# Corner article for ideas on how to reduce RichTextBox flicker.

You can use various options with FINDSTR to remove the lines do not want, like so:

DIR /S | FINDSTR "\-" | FINDSTR /VI DIR

Normal output contains entries like these:

28-Aug-14  05:14 PM    <DIR>          .
28-Aug-14  05:14 PM    <DIR>          ..

You could remove these using the various filtering options offered by FINDSTR. You can also use the excellent unxutils, but it converts the output to UNIX by default, so you no longer get CR+LF; FINDSTR offers the best Windows option.

An excerpt from the RFC 2616: Hypertext Transfer Protocol -- HTTP/1.1:

The POST method is used to request that the origin server accept the entity enclosed in the request as a new subordinate of the resource identified by the Request-URI in the Request-Line. POST is designed to allow a uniform method to cover the following functions:

• Annotation of existing resources;
• Posting a message to a bulletin board, newsgroup, mailing list, or similar group of articles;
• Providing a block of data, such as the result of submitting a form, to a data-handling process;
• Extending a database through an append operation.

Despite this being against the general SO policy on these matters, this seems to be what the OP genuinely wants:

http://www.google.com/search?btnG=1&pws=0&q=java+executable+wrapper

If you'd like, you could also try creating the appropriate batch or script file containing the single line:

java -jar MyJar.jar

Or in many cases on windows just double clicking the executable jar.

My solution:

.modal.in .modal-dialog 
{
    -webkit-transform: translate(0, calc(50vh - 50%));
    -ms-transform: translate(0, 50vh) translate(0, -50%);
    -o-transform: translate(0, calc(50vh - 50%));
    transform: translate(0, 50vh) translate(0, -50%);
}

There's a slightly better way:

int valueParsed;
if(Int32.TryParse(txtMyText.Text.Trim(), out valueParsed))
{ ... }

If you try to parse the text and it can't be parsed, the Int32.Parse method will raise an exception. I think it is better for you to use the TryParse method which will capture the exception and let you know as a boolean if any exception was encountered.

There are lot of complications in parsing text which Int32.Parse takes into account. It is foolish to duplicate the effort. As such, this is very likely the approach taken by VB's IsNumeric. You can also customize the parsing rules through the NumberStyles enumeration to allow hex, decimal, currency, and a few other styles.

Another common approach for non-web based applications is to restrict the input of the text box to only accept characters which would be parseable into an integer.

EDIT: You can accept a larger variety of input formats, such as money values ("$100") and exponents ("1E4"), by specifying the specific NumberStyles:

int valueParsed;
if(Int32.TryParse(txtMyText.Text.Trim(), NumberStyles.AllowCurrencySymbol | NumberStyles.AllowExponent, CultureInfo.CurrentCulture, out valueParsed))
{ ... }

... or by allowing any kind of supported formatting:

int valueParsed;
if(Int32.TryParse(txtMyText.Text.Trim(), NumberStyles.Any, CultureInfo.CurrentCulture, out valueParsed))
{ ... }

When we are going to migrate JQuery from 1.x to 2x or 3.x in our old existing application , then we will use .done,.fail instead of success,error as JQuery up gradation is going to be deprecated these methods.For example when we make a call to server web methods then server returns promise objects to the calling methods(Ajax methods) and this promise objects contains .done,.fail..etc methods.Hence we will the same for success and failure response. Below is the example(it is for POST request same way we can construct for request type like GET...)

 $.ajax({
            type: "POST",
            url: url,
            data: '{"name" :"sheo"}',
            contentType: "application/json; charset=utf-8",
            async: false,
            cache: false
            }).done(function (Response) {
                  //do something when get response            })
           .fail(function (Response) {
                    //do something when any error occurs.
                });

$ git push

It is just a selector that helps you select specific tag <p id = 'demo'></p> elements which help you change the behavior, in any event (either mouse or keyboard).

If you can't use that library for some reason, consider using ConcurrentHashMap instead of SynchronizedHashMap; it has a nifty putIfAbsent(K,V) method with which you can atomically add the element list if it's not already there. Also, consider using CopyOnWriteArrayList for the map values if your usage patterns warrant doing so.

But while mocking read-only properties means properties with getter method only you should declare it as virtual otherwise System.NotSupportedException will be thrown because it is only supported in VB as moq internally override and create proxy when we mock anything.

If you have an issue where you only want to remove trailing characters, you can try this:

WHILE EXISTS
(SELECT * FROM @ReportSet WHERE
    ASCII(right(addr_3,1)) = 10
    OR ASCII(right(addr_3,1)) = 13
    OR ASCII(right(addr_3,1)) = 32)
BEGIN
    UPDATE @ReportSet
    SET addr_3 = LEFT(addr_3,LEN(addr_3)-1)
    WHERE 
    ASCII(right(addr_3,1)) = 10
    OR ASCII(right(addr_3,1)) = 13
    OR ASCII(right(addr_3,1)) = 32
END

This solved a problem I had with addresses where a procedure created a field with a fixed number of lines, even if those lines were empty. To save space in my SSRS report, I cut them down.

You can fill a hidden field from your JavaScript code and do an explicit postback from JavaScript. Then from the server side, check that hiddenfield and do whatever necessary.

@heridev and I created a small function in jQuery.

jQuery

// apply the two-digits behaviour to elements with 'two-digits' as their class

            if($(this).val().split(".")[1].length > 2){                
                if( isNaN( parseFloat( this.value ) ) ) return;
                this.value = parseFloat(this.value).toFixed(2);
            }  
         }            
         return this; //for chaining

You are correct, I think the [0,len(xs)] is throwing you off. You'll want to reuse the original x-axis variable xs and plot that with another numpy array of the same length that has your variable in it.

annual = np.arange(1,21,1)
l = np.array(value_list) # a list with 20 values
spl = UnivariateSpline(annual,l)
xs = np.linspace(1,21,200)
plt.plot(xs,spl(xs),'b')

#####horizontal line
horiz_line_data = np.array([40 for i in xrange(len(xs))])
plt.plot(xs, horiz_line_data, 'r--') 
###########plt.plot([0,len(xs)],[40,40],'r--',lw=2)
pylab.ylim([0,200])
plt.show()

Hopefully that fixes the problem!

Try "pip3 install jupyter", instead of pip. It worked for me.

Because timedelta is defined like:

class datetime.timedelta([days,] [seconds,] [microseconds,] [milliseconds,] [minutes,] [hours,] [weeks])

All arguments are optional and default to 0.

You can easily say "Three days and four milliseconds" with optional arguments that way.

>>> datetime.timedelta(days=3, milliseconds=4)
datetime.timedelta(3, 0, 4000)
>>> datetime.timedelta(3, 0, 0, 4) #no need for that.
datetime.timedelta(3, 0, 4000)

And for str casting, it returns a nice formatted value instead of __repr__ to improve readability. From docs:

str(t) Returns a string in the form [D day[s], ][H]H:MM:SS[.UUUUUU], where D is negative for negative t. (5)

>>> datetime.timedelta(seconds = 42).__repr__()
'datetime.timedelta(0, 42)'
>>> datetime.timedelta(seconds = 42).__str__()
'0:00:42'

I had simular problem and fixed it with the next command

sudo pip3 install py

this ans is for eclipse user......

first u check the jdbc jar file is add in Ear libraries....

if yes...then check...in web Content->web Inf folder->lib

and past here jdbc jar file in lib folder.....

With the following, it is easy to link the Cell address...

=SUM(SUMIFS(FAGLL03!$I$4:$I$1048576,FAGLL03!$A$4:$A$1048576,">="&INDIRECT("A"&ROW()),FAGLL03!$A$4:$A$1048576,"<="&INDIRECT("B"&ROW()),FAGLL03!$Q$4:$Q$1048576,E$2))

Can use address / substitute / Column functions as required to use Cell addresses in full DYNAMIC.

floor((day(@DateValue)-1)/7)+1

best way to Round off number to decimal places is that

a=parseFloat(Math.round(numbertobeRound*10^decimalplaces)/10^decimalplaces);

for Example ;

numbertobeRound=58.8965896589;

if you want 58.90

decimalplaces is 2

a=parseFloat(Math.round(58.8965896589*10^2)/10^2);

you can use line.seperator for appending new line in

You just have to go to the AndroidManifest.xml and inside or in your activities labels, you have to type this line of code as someone up there said:

android:configChanges="orientation|screenSize"

So, you'll have something like this:

<activity android:name="ActivityMenu"
android:configChanges="orientation|screenSize">
</activity>

Hope it works!

This is an interesting question and since it isn't explained very explicitly in the documentation I'll answer this by going through the sourcecode of mod_rewrite; demonstrating a big benefit of open-source.

In the top section you'll quickly spot the defines used to name these flags:

#define CONDFLAG_NONE               1<<0
#define CONDFLAG_NOCASE             1<<1
#define CONDFLAG_NOTMATCH           1<<2
#define CONDFLAG_ORNEXT             1<<3
#define CONDFLAG_NOVARY             1<<4

and searching for CONDFLAG_ORNEXT confirms that it is used based on the existence of the [OR] flag:

else if (   strcasecmp(key, "ornext") == 0
         || strcasecmp(key, "OR") == 0    ) {
    cfg->flags |= CONDFLAG_ORNEXT;
}

The next occurrence of the flag is the actual implementation where you'll find the loop that goes through all the RewriteConditions a RewriteRule has, and what it basically does is (stripped, comments added for clarity):

# loop through all Conditions that precede this Rule
for (i = 0; i < rewriteconds->nelts; ++i) {
    rewritecond_entry *c = &conds[i];

    # execute the current Condition, see if it matches
    rc = apply_rewrite_cond(c, ctx);

    # does this Condition have an 'OR' flag?
    if (c->flags & CONDFLAG_ORNEXT) {
        if (!rc) {
            /* One condition is false, but another can be still true. */
            continue;
        }
        else {
            /* skip the rest of the chained OR conditions */
            while (   i < rewriteconds->nelts
                   && c->flags & CONDFLAG_ORNEXT) {
                c = &conds[++i];
            }
        }
    }
    else if (!rc) {
        return 0;
    }
}

You should be able to interpret this; it means that OR has a higher precedence, and your example indeed leads to if ( (A OR B) AND (C OR D) ). If you would, for example, have these Conditions:

RewriteCond A [or]
RewriteCond B [or]
RewriteCond C
RewriteCond D

it would be interpreted as if ( (A OR B OR C) and D ).

The full list is:

DB, DW, DD, DQ, DT, DDQ, and DO (used to declare initialized data in the output file.)

See: http://www.tortall.net/projects/yasm/manual/html/nasm-pseudop.html

They can be invoked in a wide range of ways: (Note: for Visual-Studio - use "h" instead of "0x" syntax - eg: not 0x55 but 55h instead):

    db      0x55                ; just the byte 0x55
    db      0x55,0x56,0x57      ; three bytes in succession
    db      'a',0x55            ; character constants are OK
    db      'hello',13,10,'$'   ; so are string constants
    dw      0x1234              ; 0x34 0x12
    dw      'A'                 ; 0x41 0x00 (it's just a number)
    dw      'AB'                ; 0x41 0x42 (character constant)
    dw      'ABC'               ; 0x41 0x42 0x43 0x00 (string)
    dd      0x12345678          ; 0x78 0x56 0x34 0x12
    dq      0x1122334455667788  ; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
    ddq     0x112233445566778899aabbccddeeff00
    ; 0x00 0xff 0xee 0xdd 0xcc 0xbb 0xaa 0x99
    ; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
    do      0x112233445566778899aabbccddeeff00 ; same as previous
    dd      1.234567e20         ; floating-point constant
    dq      1.234567e20         ; double-precision float
    dt      1.234567e20         ; extended-precision float

DT does not accept numeric constants as operands, and DDQ does not accept float constants as operands. Any size larger than DD does not accept strings as operands.

This might help you out:

    Dim diaFolder As FileDialog
    Dim Fname As String

    Set diaFolder = Application.FileDialog(msoFileDialogFolderPicker)
    diaFolder.AllowMultiSelect = False
    diaFolder.Show

    Fname = diaFolder.SelectedItems(1)

    ActiveSheet.Range("B9") = Fname

request is now deprecated. It is recommended you use an alternative

In no particular order and dreadfully incomplete:

• native HTTP/S, const https = require('https');
• node-fetch
• axios
• got
• superagent
• bent
• make-fetch-happen
• unfetch
• tiny-json-http
• needle
• urllib

Stats comparision Some code examples

Original answer:

This gets a lot easier if you use the request library.

var request = require('request');

request.post(
    'http://www.yoursite.com/formpage',
    { json: { key: 'value' } },
    function (error, response, body) {
        if (!error && response.statusCode == 200) {
            console.log(body);
        }
    }
);

Aside from providing a nice syntax it makes json requests easy, handles oauth signing (for twitter, etc.), can do multi-part forms (e.g. for uploading files) and streaming.

To install request use command npm install request

After I plotted all the lines, I was able to set the transparency of all of them as follows:

You can use MySQL JSON datatype to store the array

mysql> CREATE TABLE t1 (jdoc JSON);

Query OK, 0 rows affected (0.20 sec)

mysql> INSERT INTO t1 VALUES('{"key1": "value1", "key2": "value2"}');

Query OK, 1 row affected (0.01 sec)

To get the above object in PHP

json_encode(["key1"=> "value1", "key2"=> "value2"]);

It's short for Dimension, as it was originally used in BASIC to specify the size of arrays.

DIM — (short for dimension) define the size of arrays

Ref: http://en.wikipedia.org/wiki/Dartmouth_BASIC

A part of the original BASIC compiler source code, where it would jump when finding a DIM command, in which you can clearly see the original intention for the keyword:

DIM    LDA XR01             BACK OFF OBJECT POINTER
       SUB N3
       STA RX01
       LDA L        2       GET VARIABLE TO BE DIMENSIONED
       STA 3
       LDA S        3
       CAB N36              CHECK FOR $ ARRAY
       BRU *+7              NOT $
       ...

Ref: http://dtss.dartmouth.edu/scans/BASIC/BASIC%20Compiler.pdf

Later on it came to be used to declare all kinds of variables, when the possibility to specify the type for variables was added in more recent implementations.

An unmodifiable map may still change. It is only a view on a modifiable map, and changes in the backing map will be visible through the unmodifiable map. The unmodifiable map only prevents modifications for those who only have the reference to the unmodifiable view:

Map<String, String> realMap = new HashMap<String, String>();
realMap.put("A", "B");

Map<String, String> unmodifiableMap = Collections.unmodifiableMap(realMap);

// This is not possible: It would throw an 
// UnsupportedOperationException
//unmodifiableMap.put("C", "D");

// This is still possible:
realMap.put("E", "F");

// The change in the "realMap" is now also visible
// in the "unmodifiableMap". So the unmodifiableMap
// has changed after it has been created.
unmodifiableMap.get("E"); // Will return "F". 

In contrast to that, the ImmutableMap of Guava is really immutable: It is a true copy of a given map, and nobody may modify this ImmutableMap in any way.

Update:

As pointed out in a comment, an immutable map can also be created with the standard API using

Map<String, String> immutableMap = 
    Collections.unmodifiableMap(new LinkedHashMap<String, String>(realMap)); 

This will create an unmodifiable view on a true copy of the given map, and thus nicely emulates the characteristics of the ImmutableMap without having to add the dependency to Guava.

I think the commands you are looking for are:

cd repo2
git checkout master
git remote add r1remote **url-of-repo1**
git fetch r1remote
git merge r1remote/master --allow-unrelated-histories
git remote rm r1remote

After that repo2/master will contain everything from repo2/master and repo1/master, and will also have the history of both of them.

Java strings are simply an array of char. So, char c = s[0] where s is string.

If you are working with Windows and Visual Studio 2015

• Install miniconda http://conda.pydata.org/miniconda.html
• Change your python environment to python 3.4 (32bit)
• click on python environment 3.4 and open cmd

Enter the following commands

• "conda install numpy"
• "conda install pandas"
• "conda install scipy"

The easiest way to do so is using jQuery and animate.css animation library.

Javascript

/* --- Show DIV --- */
$( '.example' ).removeClass( 'fadeOutRight' ).show().addClass( 'fadeInRight' );

/* --- Hide DIV --- */
$( '.example' ).removeClass( 'fadeInRight' ).addClass( 'fadeOutRight' );

HTML

<div class="example">Some text over here.</div>

Easy enough to implement. Just don't forget to include the animate.css file in the header :)

This is probably more verbose than you want, but you're asking for a slightly complex operation so actual code might be involved (the horror).

My recommendation, with zipObject that's pretty logical:

_.zipObject(_.map(params, 'name'), _.map(params, 'input'));

Another option, more hacky, using fromPairs:

_.fromPairs(_.map(params, function(val) { return [val['name'], val['input']));

The anonymous function shows the hackiness -- I don't believe JS guarantees order of elements in object iteration, so callling .values() won't do.

Cmd below solved my problem:

$ sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

In my case, I upgraded to Xcode 8 and downloaded another version 7.3.1 later (renamed it to "Xcode 7.3.1"), then cannot get the simulator list in Xcode 8.

Try this:

$('select[name="' + name + '"] option:selected').val();

This will get the selected value of your menu.

I found this code working:

from distutils.dir_util import copy_tree

# copy subdirectory example
fromDirectory = "/a/b/c"
toDirectory = "/x/y/z"

copy_tree(fromDirectory, toDirectory)

Reference:

• Python 2: https://docs.python.org/2/distutils/apiref.html#distutils.dir_util.copy_tree
• Python 3: https://docs.python.org/3/distutils/apiref.html#distutils.dir_util.copy_tree

This functions should help you...

bool isThereSpace(String s){
    return s.Contains(" ");
}

Request.Url.PathAndQuery

should work perfectly, especially if you only want the relative Uri (but keeping querystrings)

guys This error because of Element Id not Visible from js Try to inspect element from UI and paste it on javascript file:

Incomplete information: we need to know which line is throwing the NullReferenceException in order to tell precisely where the problem lies.

Obviously, you are using an uninitialized variable (i.e., a variable that has been declared but not initialized) and try to access one of its non-static method/property/whatever.

Solution: - Find the line that is throwing the exception from the exception details - In this line, check that every variable you are using has been correctly initialized (i.e., it is not null)

Good luck.

Follow bellow steps:

shell> mysqldump -hlocalhost -uroot -p  database1  > dump.sql

mysql> CREATE DATABASE database2;

shell> mysql -hlocalhost -uroot -p database2 < dump.sql

If you want to drop database1 otherwise leave it.

mysql> DROP DATABASE database1;

Note : shell> denote command prompt and mysql> denote mysql prompt.

Make sure your jquery is inside $(document).ready function or similar.

Also you can improve your code by using jquery data

$('#amount').data('min','1000');

<div id="amount" data-min=""></div>

Update,

A working example of your full code (pretty much) here. http://jsfiddle.net/blowsie/c6VAy/3/

Try the following:

df[df['Col2'].isnull()]

Below code with Redirected "while-read" loop works fine for me

while read LINE
do
      let count++
      echo "$count $LINE"

done < $FILENAME

echo -e "\nTotal $count Lines read"

Use LinkedHashMap and use this function.

private LinkedHashMap<Integer, String> map = new LinkedHashMap<Integer, String>();

Define like this and.

private Entry getEntry(int id){
        Iterator iterator = map.entrySet().iterator();
        int n = 0;
        while(iterator.hasNext()){
            Entry entry = (Entry) iterator.next();
            if(n == id){
                return entry;
            }
            n ++;
        }
        return null;
    }

The function can return the selected entry.

I would use the first one. It is clear to see right away what it does. I dont think the null check is necessary here.

Edit

This answer is now deprecated. See the answer by apsillers.

Since this is for a Chrome extension, you might as well use the standard DOM event - DOMSubtreeModified. See the support for this event across browsers. It has been supported in Chrome since 1.0.

$("#someDiv").bind("DOMSubtreeModified", function() {
    alert("tree changed");
});

See a working example here.

If you want to do the following by using JSTL Tag Libe, please follow the following steps:

[Requirement] if a number is a grater than equal 40 and lower than 50 then display "Two digit number starting with 4" otherwise "Other numbers".

[Solutions]

1. Please Add the JSTL tag lib on the top of the page.`
     <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>`

2. Please Write the following code
`
<c:choose>
       <c:when test="${params.number >=40 && params.number <50}">
              <p> Two digit number starting with 4. </p>
       </c:when>
       <c:otherwise>
              <p> Other numbers. </p>
       </c:otherwise>
  </c:choose>`

If you want to encode URI path components, you can also use standard JDK functions, e.g.

public static String encodeURLPathComponent(String path) {
    try {
        return new URI(null, null, path, null).toASCIIString();
    } catch (URISyntaxException e) {
        // do some error handling
    }
    return "";
}

The URI class can also be used to encode different parts of or whole URIs.

To compare local repository with remote one, simply use the below syntax:

git diff @{upstream}

Or, if you need to do something with each folder, have a look at the System.IO.DirectoryInfo class. It also has a Parent property that allows you to navigate to the parent directory.

I had a same problem because I installed both of python2.7 and python3. when I run program with python3 I received same error. I install scipy with this command and problem has been solved:

sudo apt-get install python3-scipy

Use quit() in this context. break expects to be inside a loop, and return expects to be inside a function.

I had the same problem and trouble getting it to work on all browsers.

So this is the best font stack for Helvetica Neue Condensed Bold I could find:
