Inside single quotes everything is preserved literally, without exception.

That means you have to close the quotes, insert something, and then re-enter again.

'before'"$variable"'after'
'before'"'"'after'
'before'\''after'

Word concatenation is simply done by juxtaposition. As you can verify, each of the above lines is a single word to the shell. Quotes (single or double quotes, depending on the situation) don't isolate words. They are only used to disable interpretation of various special characters, like whitespace, $, ;... For a good tutorial on quoting see Mark Reed's answer. Also relevant: Which characters need to be escaped in bash?

Do not concatenate strings interpreted by a shell

You should absolutely avoid building shell commands by concatenating variables. This is a bad idea similar to concatenation of SQL fragments (SQL injection!).

Usually it is possible to have placeholders in the command, and to supply the command together with variables so that the callee can receive them from the invocation arguments list.

For example, the following is very unsafe. DON'T DO THIS

script="echo \"Argument 1 is: $myvar\""
/bin/sh -c "$script"

If the contents of $myvar is untrusted, here is an exploit:

myvar='foo"; echo "you were hacked'

Instead of the above invocation, use positional arguments. The following invocation is better -- it's not exploitable:

script='echo "arg 1 is: $1"'
/bin/sh -c "$script" -- "$myvar"

Note the use of single ticks in the assignment to script, which means that it's taken literally, without variable expansion or any other form of interpretation.

Use the %02X format parameter:

printf("%02X",word[i]);

In javascript/jquery most of the developer uses From & To date comparison which is string, without converting into date format. The simplest way to compare from date is greater then to date is.

Date.parse(fromDate) > Date.parse(toDate)

Always parse from and to date before comparison to get accurate results

I just found a simple solution. You can drag an opened file and move towards the four sides of the Editor, it will show a highlighted area that you can drop to. It will split the view automatically, either horizontally, vertically, or even into three rows.

VSCode v1.30.2

Update: you can also drag a file from the Explorer to split the Editor in the same way above.

Dictionary Class is exactly what you want, correct.

You can declare the field directly as Dictionary, instead of IDictionary, but that's up to you.

Create an SSLSocket factory yourself, and set it on the HttpsURLConnection before connecting.

...
HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
conn.setSSLSocketFactory(sslFactory);
conn.setMethod("POST");
...

You'll want to create one SSLSocketFactory and keep it around. Here's a sketch of how to initialize it:

/* Load the keyStore that includes self-signed cert as a "trusted" entry. */
KeyStore keyStore = ... 
TrustManagerFactory tmf = 
  TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(keyStore);
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(null, tmf.getTrustManagers(), null);
sslFactory = ctx.getSocketFactory();

If you need help creating the key store, please comment.

Here's an example of loading the key store:

KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
keyStore.load(trustStore, trustStorePassword);
trustStore.close();

To create the key store with a PEM format certificate, you can write your own code using CertificateFactory, or just import it with keytool from the JDK (keytool won't work for a "key entry", but is just fine for a "trusted entry").

keytool -import -file selfsigned.pem -alias server -keystore server.jks

if you use pg_dump with -Fp to backup in plain text format, use following command:

cat db.txt | psql dbname

to copy all data to your database with name dbname

You can mark it as @JsonIgnore.

With 1.9, you can add @JsonIgnore for getter, @JsonProperty for setter, to make it deserialize but not serialize.

var stringNumb: String = "1357"
var someNumb = Int(stringNumb)

or

var stringNumb: String = "1357"
var someNumb:Int? = Int(stringNumb)

Int(String) returns an optional Int?, not an Int.

Safe use: do not explicitly unwrap

let unwrapped:Int = Int(stringNumb) ?? 0

or

if let stringNumb:Int = stringNumb { ... }

(*) None of the answers actually addressed why var someNumb: Int = Int(stringNumb) was not working.

If checkout master was the last thing you did, then the reflog entry HEAD@{1} will contain your commits (otherwise use git reflog or git log -p to find them). Use git merge HEAD@{1} to fast forward them into master.

EDIT:

As noted in the comments, Git Ready has a great article on this.

git reflog and git reflog --all will give you the commit hashes of the mis-placed commits.

Source: http://gitready.com/intermediate/2009/02/09/reflog-your-safety-net.html

In order to query a table for the number of rows in that table, you want your query to be as efficient as possible. Reference.

Use something like this:

/**
 * Query the Number of Entries in a Sqlite Table
 * */
public long QueryNumEntries()
{
    SQLiteDatabase db = this.getReadableDatabase();
    return DatabaseUtils.queryNumEntries(db, "table_name");
}

You can use text.

text(x, y, s, fontsize=12)

text coordinates can be given relative to the axis, so the position of your text will be independent of the size of the plot:

The default transform specifies that text is in data coords, alternatively, you can specify text in axis coords (0,0 is lower-left and 1,1 is upper-right). The example below places text in the center of the axes::

text(0.5, 0.5,'matplotlib',
     horizontalalignment='center',
     verticalalignment='center',
     transform = ax.transAxes)

To prevent the text to interfere with any point of your scatter is more difficult afaik. The easier method is to set y_axis (ymax in ylim((ymin,ymax))) to a value a bit higher than the max y-coordinate of your points. In this way you will always have this free space for the text.

EDIT: here you have an example:

In [17]: from pylab import figure, text, scatter, show
In [18]: f = figure()
In [19]: ax = f.add_subplot(111)
In [20]: scatter([3,5,2,6,8],[5,3,2,1,5])
Out[20]: <matplotlib.collections.CircleCollection object at 0x0000000007439A90>
In [21]: text(0.1, 0.9,'matplotlib', ha='center', va='center', transform=ax.transAxes)
Out[21]: <matplotlib.text.Text object at 0x0000000007415B38>
In [22]:

The ha and va parameters set the alignment of your text relative to the insertion point. ie. ha='left' is a good set to prevent a long text to go out of the left axis when the frame is reduced (made narrower) manually.

Note however:

If you issue SET TRANSACTION ISOLATION LEVEL in a stored procedure or trigger, when the object returns control the isolation level is reset to the level in effect when the object was invoked. For example, if you set REPEATABLE READ in a batch, and the batch then calls a stored procedure that sets the isolation level to SERIALIZABLE, the isolation level setting reverts to REPEATABLE READ when the stored procedure returns control to the batch.

Although there are many solutions offered already, I recommend the following two:

1. HTM2PDF - offers an API to convert HTML to PDF and also has a PHP SDK, which makes it very easy to implement in PHP; It offers a choice of server locations in Europe, Asia and the USA
2. PDFmyURL - offers an API that does URL and HTML to PDF as well, with roughly the same functionality as HTM2PDF, but works on a load balanced landscape and has been around a little longer

The thing that's different about these two APIs from all the previously mentioned solutions, is that - besides converting HTML to PDF with CSS and JavaScript - it also offers PDF rights management, watermarking and encryption. Therefore it's an all-in-one solution for those who want to hit the ground running.

Disclaimer: I work for Kaiomi, a company that operates both of these websites.

I couldn't copy files using the answers above but I have putty and I found a workaround on Quora.

1. Change settings of your PuTTY session, go to logging and change it to "printable characters". Set the log file
2. Do a cat of the respective file
3. Go to the file you set in step #1 and you will have your content in the log file.

Note: it copies all the printed characters of that session to the log file, so it will get big eventually. In that case, delete the log file and cat the target file so you get that particular file's content copied on your machine.

you can easily resolve this problem by changing the port number of glassfish.

Go to glassfich configuration File domain.xml which is located under GlassFish_Server\glassfish\domains\domain1\config.

Open this file, then change the following line:

<network-listener port="8080" protocol="http-listener-1" transport="tcp" 
name="http-listener-1" thread-pool="http-thread-pool"></network-listener>  

replace 8080 by 9090 for example, then save file and run glassfish again. it should nicely work.

I had a similar issue for weeks but i had the design lib version with + in my build.gradle which made it download the latest version. So i set it to the version of the package and it worked.

With Visual Studio 1.43 (Q1 2020), the Ctrl+K then O keyboard shortcut will work for a file.

See issue 89989:

It should be possible to e.g. invoke the "Open Active File in New Window" command and open that file into an empty workspace in the web.

To complement Jakub's answer, if you have access to the remote git server in ssh, you can go into the git remote directory and set:

user@remote$ git config receive.denyNonFastforwards false

Then go back to your local repo, try again to do your commit with --force:

user@local$ git push origin +master:master --force

And finally revert the server's setting in the original protected state:

user@remote$ git config receive.denyNonFastforwards true

string::c.str() returns a string of type const char * as seen here

A quick fix: try casting printfunc(num,addr,(char *)data.str().c_str());

While the above may work, it is undefined behaviour, and unsafe.

Here's a nicer solution using templates:

char * my_argument = const_cast<char*> ( ...c_str() );

I know there is already an answer to this but I just found a better solution using the variableWidth parameter, just set it to true in the settings of each breakpoint, like this:

$('#featured-articles').slick({
  arrows: true,
  autoplay: true,
  autoplaySpeed: 3000,
  dots: true,
  draggable: false,
  fade: true,
  infinite: false,
  responsive: [
  {
    breakpoint: 620,
    settings: {
        arrows: true,
        variableWidth: true
    }
  },
  {
    breakpoint: 345,
    settings: {
        arrows: true,
        variableWidth: true
    }
  }
  ]
});

You will need to create a virtual device that runs on ARM. Virtual devices running on X86 require an Intel processor. AMD support as specified by Android is only available for Linux systems. If you want a better experience when creating your Virtual Device, use "Store a snapshot for faster startup" instead of the default "Use Host GPU".

Previous answers are correct but here is one more way of doing this and some tips:

Option #1 Go to you Jenkins job and search for "add build step" and then just copy and paste your script there

Option #2 Go to Jenkins and do the same again "add build step" but this time put the fully qualified path for your script in there example : ./usr/somewhere/helloWorld.sh

things to watch for /tips:

• Environment variables, if your job is running at the same time then you need to worry about concurrency issues. One job may be setting the value of environment variables and the next may use the value or take some action based on that incorrectly.
• Make sure all paths are fully qualified
• Think about logging /var/log or somewhere so you would also have something to go to on the server (optional)
• thing about space issue and permissions, running out of space and permission issues are very common in linux environment
• Alerting and make sure your script/job fails the jenkin jobs when your script fails

I recently read Dreaming in Code and found it to be an interesting read. Perhaps more so since the day I started reading it Chandler 1.0 was released. Reading about the growing pains and mistakes of a project team of talented people trying to "change the world" gives you a lot to learn from. Also Scott brings up a lot of programmer lore and wisdom in between that's just an entertaining read.

Beautiful Code had one or two things that made me think differently, particularly the chapter on top down operator precedence.

I already said that I was new to exec() function. After doing some more digging, I came upon 2>&1 which needs to be added at the end of command in exec().

Thanks @mattosmat for pointing it out in the comments too. I did not try this at once because you said it is a Linux command, I am on Windows.

So, what I have discovered, the command is actually executing in the back-end. That is why I could not see it actually running, which I was expecting to happen.

For all of you, who had similar problem, my advise is to use that command. It will point out all the errors and also tell you info/details about execution.

exec('some_command 2>&1', $output);
print_r($output);  // to see the response to your command

Thanks for all the help guys, I appreciate it ;)

Use element.outerHTML to get full representation of element, including outer tags and attributes.

With SASS Bootstrap - if you are compiling Bootstrap yourself - you can set all border radius (or more specific) simply to zero:

$border-radius:               0;
$border-radius-lg:            0;
$border-radius-sm:            0;

I have increased target in my tsconfig.json to enable this feature in TypeScript

{
    "compilerOptions": {
        "target": "es2017",
        ......
    }
}

To add to Silfheed's answer, which was useful, I needed to patch multiple methods of the object in question. I found it more elegant to do it this way:

Given the following function to test, located in module.a_function.to_test.py:

from some_other.module import SomeOtherClass

def add_results():
    my_object = SomeOtherClass('some_contextual_parameters')
    result_a = my_object.method_a()
    result_b = my_object.method_b()
    
    return result_a + result_b

To test this function (or class method, it doesn't matter), one can patch multiple methods of the class SomeOtherClass by using patch.object() in combination with sys.modules:

@patch.object(sys.modules['module.a_function.to_test'], 'SomeOtherClass')
def test__should_add_results(self, mocked_other_class):
  mocked_other_class().method_a.return_value = 4
  mocked_other_class().method_b.return_value = 7

  self.assertEqual(add_results(), 11)

This works no matter the number of methods of SomeOtherClass you need to patch, with independent results.

Also, using the same patching method, an actual instance of SomeOtherClass can be returned if need be:

@patch.object(sys.modules['module.a_function.to_test'], 'SomeOtherClass')
def test__should_add_results(self, mocked_other_class):
  other_class_instance = SomeOtherClass('some_controlled_parameters')
  mocked_other_class.return_value = other_class_instance 
  ...

Another Option (was handy for our scenario):

We have a User Table, storing ADName, LastName, FirstName

• Users should be alphabetical
• Accounts with no First- / LastName as well, based on their ADName - but at the end of the User-List
• Dummy User with ID "0" ("No Selection") Should be topmost always.

We altered the table schema and added a "SortIndex" Column, which defines some sorting groups. (We left a gap of 5, so we can insert groups later)

ID | ADName |      First Name | LastName | SortIndex
0    No Selection  null         null     | 0
1    AD\jon        Jon          Doe      | 5
3    AD\Support    null         null     | 10     
4    AD\Accounting null         null     | 10
5    AD\ama        Amanda       Whatever | 5

Now, query-wise it would be:

SELECT * FROM User order by SortIndex, LastName, FirstName, AdName;

in Method Expressions:

db.User.OrderBy(u => u.SortIndex).ThenBy(u => u.LastName).ThenBy(u => u.FirstName).ThenBy(u => u.AdName).ToList();

which yields the expected result:

ID | ADName |      First Name | LastName | SortIndex
0    No Selection  null         null     | 0
5    AD\ama        Amanda       Whatever | 5
1    AD\jon        Jon          Doe      | 5
4    AD\Accounting null         null     | 10
3    AD\Support    null         null     | 10     

Well if you store the data as UTC date in the database you can do something as simple as

select 
 [MyUtcDate] + getdate() - getutcdate()
from [dbo].[mytable]

this was it's always local from the point of the server and you are not fumbling with AT TIME ZONE 'your time zone name', if your database get moved to another time zone like a client installation a hard coded time zone might bite you.

Simplest Way

<TableRow>
    <TextView android:id="@+id/address1"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:gravity="left"
        android:maxLines="4" 
        android:singleLine="false"              
        android:text="Johar Mor,\n Gulistan-e-Johar,\n Karachi" >
    </TextView> 
</TableRow>

Use \n where you want to insert a new line Hopefully it will help you

I just tested and for me, none of the other solutions worked. I simply tried this and it worked perfectly on Firefox and Chrome, just as I had expected:

<div class='wrap'>
    <iframe ...></iframe>
</div>

and the css:

.wrap {
    width: 640px;
    height: 480px;
    overflow: hidden;
}

iframe {
    width: 76.92% !important;
    height: 76.92% !important;
    -webkit-transform: scale(1.3);
    transform: scale(1.3);
    -webkit-transform-origin: 0 0;
    transform-origin: 0 0;
}

This scales all the content by 30%. The width/height percentages of course need to be adjusted accordingly (1/scale_factor).

Split on tab, but then remove all blank matches.

text = "hi\tthere\t\t\tmy main man"
print [splits for splits in text.split("\t") if splits is not ""]

Outputs:

['hi', 'there', 'my main man']

your code

SELECT * FROM Cases WHERE created_at BETWEEN '2013-05-01' AND '2013-05-01'

how SQL reading it

SELECT * FROM Cases WHERE '2013-05-01 22:25:19' BETWEEN '2013-05-01 00:00:00' AND '2013-05-01 00:00:00'

if you don't mention time while comparing DateTime and Date by default hours:minutes:seconds will be zero in your case dates are the same but if you compare time created_at is 22 hours ahead from your end date range

if the above is clear you fix this in many ways like putting ending hours in your end date eg BETWEEN '2013-05-01' AND ''2013-05-01 23:59:59''

OR

simply cast create_at as date like cast(created_at as date) after casting as date '2013-05-01 22:25:19' will be equal to '2013-05-01 00:00:00'

In Rails 2, I would have written:

validates_uniqueness_of :zipcode, :scope => :recorded_at

In Rails 3:

validates :zipcode, :uniqueness => {:scope => :recorded_at}

For multiple attributes:

validates :zipcode, :uniqueness => {:scope => [:recorded_at, :something_else]}

// .blur is triggered when element loses focus

$('#target').blur(function() {
  alert($(this).val());
});

// To trigger manually use:

$('#target').blur();

I like to do this

input[type="text"]
{
    background: rgba(0, 0, 0, 0);
    border: none;
    outline: none;
}

Setting the outline property to none stops the browser from highlighting the box when the cursor enters

There are a bunch of reasons here: http://macresearch.org/difference-between-alloc-init-and-new

Some selected ones are:

• new doesn't support custom initializers (like initWithString)
• alloc-init is more explicit than new

General opinion seems to be that you should use whatever you're comfortable with.

In short, yes. But there are times when you might favor one vs. the other. Google "case switch vs. if else". There are some discussions already on SO too. Also, here is a good video that talks about it in the context of MATLAB:

http://blogs.mathworks.com/pick/2008/01/02/matlab-basics-switch-case-vs-if-elseif/

Personally, when I have 3 or more cases, I usually just go with case/switch.

In current release

Assuming you have handled the verification of the request to reset the forgotten password, use following code as a sample code steps.

ApplicationDbContext =new ApplicationDbContext()
String userId = "<YourLogicAssignsRequestedUserId>";
String newPassword = "<PasswordAsTypedByUser>";
ApplicationUser cUser = UserManager.FindById(userId);
String hashedNewPassword = UserManager.PasswordHasher.HashPassword(newPassword);
UserStore<ApplicationUser> store = new UserStore<ApplicationUser>();            
store.SetPasswordHashAsync(cUser, hashedNewPassword);

In AspNet Nightly Build

The framework is updated to work with Token for handling requests like ForgetPassword. Once in release, simple code guidance is expected.

Update:

This update is just to provide more clear steps.

ApplicationDbContext context = new ApplicationDbContext();
UserStore<ApplicationUser> store = new UserStore<ApplicationUser>(context);
UserManager<ApplicationUser> UserManager = new UserManager<ApplicationUser>(store);
String userId = User.Identity.GetUserId();//"<YourLogicAssignsRequestedUserId>";
String newPassword = "test@123"; //"<PasswordAsTypedByUser>";
String hashedNewPassword = UserManager.PasswordHasher.HashPassword(newPassword);                    
ApplicationUser cUser = await store.FindByIdAsync(userId);
await store.SetPasswordHashAsync(cUser, hashedNewPassword);
await store.UpdateAsync(cUser);

If your computer is a 64bit, all you need to do is uninstall your Java x86 version and install a 64bit version. I had the same problem and this worked. Nothing further needs to be done.

Might wanna check this, got everything you need for your app icons

update

I think by default it uses your launcher icon... Your best bet is to create a separate image... Designed for the action bar and using that. For that check: http://developer.android.com/guide/topics/ui/actionbar.html#ActionItems

there is a command called dialog which uses the ncurses library. "Dialog is a program that will let you to present a variety of questions or display messages using dialog boxes from a shell script. These types of dialog boxes are implemented (though not all are necessarily compiled into dialog)"

I do not know if you are talking about a footer within your actual graphic or the url the print process within the browser is doing.

If its the url the print process is doing its really up to the browser if he has a feature to turn that off.

If its the footer information i would recommend using a print stylesheet and within that stylesheet to do

display: none;

For the particular ID or class of the footer.

To do a print stylesheet, you need to add this to the head.

<link rel="stylesheet" type="text/css" href="/css/print.css" media="print" />

First change the method parameter Enum supportedPermissions to SupportedPermissions supportedPermissions.

Then create your file like this

file = new File
{  
    Name = name,
    Id = id,
    Description = description,
    SupportedPermissions = supportedPermissions
};

And the call to your method should be

CreateFile(id, name, description, SupportedPermissions.basic);

The easiest solution is to convert your categorical variable to a factor prior to the subsetting. Bottomline is that you need a factor variable with exact the same levels in all your subsets.

library(ggplot2)
dataset <- data.frame(category = rep(LETTERS[1:5], 100), 
    x = rnorm(500, mean = rep(1:5, 100)), y = rnorm(500, mean = rep(1:5, 100)))
dataset$fCategory <- factor(dataset$category)
subdata <- subset(dataset, category %in% c("A", "D", "E"))

With a character variable

ggplot(dataset, aes(x = x, y = y, colour = category)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = category)) + geom_point()

With a factor variable

ggplot(dataset, aes(x = x, y = y, colour = fCategory)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = fCategory)) + geom_point()

You could also just do it in one go, by doing the sort first and using head to take the first 3 of each group.

In[34]: df.sort_values(['job','count'],ascending=False).groupby('job').head(3)

Out[35]: 
   count     job source
4      7   sales      E
2      6   sales      C
1      4   sales      B
5      5  market      A
8      4  market      D
6      3  market      B

This question is old and so are the correct previous answers. But what I was looking for when I found this topic was something like this solution. Hopefully it helps someone.

public class MySQLExample {
  public void run(String sql) {
    // JDBC driver name and database URL

You need to set the Format of the DateTimePicker to Custom and then assign the CustomFormat.

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
    DateTimePicker1.Format = DateTimePickerFormat.Custom
    DateTimePicker1.CustomFormat = "dd/MM/yyyy"
End Sub

You can use dapper library:

conn2.Execute(@"INSERT INTO klant(klant_id,naam,voornaam) VALUES (@p1,@p2,@p3)", 
                new { p1 = klantId, p2 = klantNaam, p3 = klantVoornaam });

BTW Dapper is a Stack Overflow project :)

UPDATE: I believe you can't do it simpler without something like EF. Also try to use using statements when you are working with database connections. This will close connection automatically, even in case of exception. And connection will be returned to connections pool.

private readonly string _spionshopConnectionString;

private void Form1_Load(object sender, EventArgs e)
{            
    _spionshopConnectionString = ConfigurationManager
          .ConnectionStrings["connSpionshopString"].ConnectionString;
}

private void button4_Click(object sender, EventArgs e)
{
    using(var connection = new SqlConnection(_spionshopConnectionString))
    {
         connection.Execute(@"INSERT INTO klant(klant_id,naam,voornaam) 
                              VALUES (@klantId,@klantNaam,@klantVoornaam)",
                              new { 
                                      klantId = Convert.ToInt32(textBox1.Text), 
                                      klantNaam = textBox2.Text, 
                                      klantVoornaam = textBox3.Text 
                                  });
    }
}

This landed in Chrome on 2012-08-26 Not sure about the exact version, I noticed it in Chrome 24.

A screenshot is worth a million words:

I am inspecting an object with methods in the Console. Clicking on the "Show function definition" takes me to the place in the source code where the function is defined. Or I can just hover over the function () { word to see function body in a tooltip. You can easily inspect the whole prototype chain like this! CDT definitely rock!!!

Hope you all find it helpful!

Try this for creating a column3 as a sum of column1 + column 2 in a table

tablename$column3=rowSums(cbind(tablename$column1,tablename$column2))

Well in order to do this, you are not limited with the Class abstraction of ES6. Accessing the parent constructor's prototype methods is possible through the __proto__ property (I am pretty sure there will be fellow JS coders to complain that it's depreciated) which is depreciated but at the same time discovered that it is actually an essential tool for sub-classing needs (especially for the Array sub-classing needs though). So while the __proto__ property is still available in all major JS engines that i know, ES6 introduced the Object.getPrototypeOf() functionality on top of it. The super() tool in the Class abstraction is a syntactical sugar of this.

So in case you don't have access to the parent constructor's name and don't want to use the Class abstraction you may still do as follows;

function ChildObject(name) {
    // call the parent's constructor
    ParentObject.call(this, name);
    this.myMethod = function(arg) {
    //this.__proto__.__proto__.myMethod.call(this,arg);
    Object.getPrototypeOf(Object.getPrototypeOf(this)).myMethod.call(this,arg);
    }
}

just disable "world wide web publishing service" , it solve my problem.

The following code will negate the enter key from being used to submit a form, but will still allow you to use the enter key in a textarea. You can edit it further depending on your needs.

<script type="text/javascript">
        function stopRKey(evt) {
          var evt = (evt) ? evt : ((event) ? event : null);
          var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
          if ((evt.keyCode == 13) && ((node.type=="text") || (node.type=="radio") || (node.type=="checkbox")) )  {return false;}
        }

        document.onkeypress = stopRKey;
</script> 

Tested these options with python3.5 and pip 9.0.3:

pip install --target /myfolder [packages]

Installs ALL packages including dependencies under /myfolder. Does not take into account that dependent packages are already installed elsewhere in Python. You will find packages from /myfolder/[package_name]. In case you have multiple Python versions, this doesn't take that into account (no Python version in package folder name).

pip install --prefix /myfolder [packages]

Checks are dependencies already installed. Will install packages into /myfolder/lib/python3.5/site-packages/[packages]

pip install --root /myfolder [packages]

Checks dependencies like --prefix but install location will be /myfolder/usr/local/lib/python3.5/site-packages/[package_name].

pip install --user [packages]

Will install packages into $HOME: /home/[USER]/.local/lib/python3.5/site-packages Python searches automatically from this .local path so you don't need to put it to your PYTHONPATH.

=> In most of the cases --user is the best option to use. In case home folder can't be used because of some reason then --prefix.

You can pass it as Action<string> - which means it is a method with a single parameter of type string that doesn't return anything (void) :

public void DoRequest(string request, Action<string> callback)
{
    // do stuff....
    callback("asdf");
}

I believe, you need to capture this.

cat ./script.sh | ssh <user>@<host>

After ?o many tries I got my solution

I have commented this line

app.use(bodyParser.json());

and I put

app.use(bodyParser.json({limit: '50mb'}))

Then it works

Replace in your views (blade files) all

{{route('/')}} ----- by ----> {{url('/')}}

I have found the above answer to be the best solution, but I don't like the leading space before the percent sign. I have seen somewhat complicated solutions, but I just use this Replace addition to the answer above instead of using other rounding solutions.

String.Format("Value: {0:P2}.", 0.8526).Replace(" %","%") // formats as 85.26% (varies by culture)

Adding more to Andreas' answer. I had the same problem with ES6 code, but I did not want to mutate the imports. That looked hacky. So I did this:

import myModule from '../myModule';
import dependency from '../dependency';
jest.mock('../dependency');

describe('myModule', () => {
  it('calls the dependency with double the input', () => {
    myModule(2);
  });
});

And added file dependency.js in the " __ mocks __" folder parallel to file dependency.js. This worked for me. Also, this gave me the option to return suitable data from the mock implementation. Make sure you give the correct path to the module you want to mock.

Adding to the crazy ideas: with Python 3 accepting unicode identifiers, you could declare a variable ? = frozenset() (? is U+03D5) and use it instead.

I, too, have need for this! My situation involves comparing actuals with budget for cost centers, where expenses may have been mis-applied and therefore need to be re-allocated to the correct cost center so as to match how they were budgeted. It is very time consuming to try and scan row-by-row to see if each expense item has been correctly allocated. I decided that I should apply conditional formatting to highlight any cells where the actuals did not match the budget. I set up the conditional formatting to change the background color if the actual amount under the cost center did not match the budgeted amount.

Here's what I did:

Start in cell A1 (or the first cell you want to have the formatting). Open the Conditional Formatting dialogue box and select Apply formatting based on a formula. Then, I wrote a formula to compare one cell to another to see if they match:

=A1=A50

If the contents of cells A1 and A50 are equal, the conditional formatting will be applied. NOTICE: no $$, so the cell references are RELATIVE! Therefore, you can copy the formula from cell A1 and PasteSpecial (format). If you only click on the cells that you reference as you write your conditional formatting formula, the cells are by default locked, so then you wouldn't be able to apply them anywhere else (you would have to write out a new rule for each line- YUK!)

What is really cool about this is that if you insert rows under the conditionally formatted cell, the conditional formatting will be applied to the inserted rows as well!

Something else you could also do with this: Use ISBLANK if the amounts are not going to be exact matches, but you want to see if there are expenses showing up in columns where there are no budgeted amounts (i.e., BLANK) .

This has been a real time-saver for me. Give it a try and enjoy!

You can access the function itself using arguments.callee ^[MDN]:

if (counter>0) {
    arguments.callee(counter-1);
}

This will break in strict mode, however.

You want multiple lines of text indented on the left. Try the following:

CSS:

    margin-left: 10px;
}

span.info {
    color: #b1b1b1;
    font-size: 11px;
    font-style: italic;
    font-weight:bold;
}

HTML:

<div class="info"><span class="info">blah blah <br/> blah blah</span></div>

tl;dr: Do not use unique_ptr's like that.

I believe you're making a terrible mess - for those who will need to read your code, maintain it, and probably those who need to use it.

1. Only take unique_ptr constructor parameters if you have publicly-exposed unique_ptr members.

unique_ptrs wrap raw pointers for ownership & lifetime management. They're great for localized use - not good, nor in fact intended, for interfacing. Wanna interface? Document your new class as ownership-taking, and let it get the raw resource; or perhaps, in the case of pointers, use owner<T*> as suggested in the Core Guidelines.

Only if the purpose of your class is to hold unique_ptr's, and have others use those unique_ptr's as such - only then is it reasonable for your constructor or methods to take them.

2. Don't expose the fact that you use unique_ptrs internally

Using unique_ptr for list nodes is very much an implementation detail. Actually, even the fact that you're letting users of your list-like mechanism just use the bare list node directly - constructing it themselves and giving it to you - is not a good idea IMHO. I should not need to form a new list-node-which-is-also-a-list to add something to your list - I should just pass the payload - by value, by const lvalue ref and/or by rvalue ref. Then you deal with it. And for splicing lists - again, value, const lvalue and/or rvalue.

I'd avoid modifying the chart.js code to accomplish this, since it's pretty easy with regular CSS and HTML. Here's my solution:

HTML:

<canvas id="productChart1" width="170"></canvas>
<div class="donut-inner">
    <h5>47 / 60 st</h5>
    <span>(30 / 25 st)</span>
</div>

CSS:

.donut-inner {
   margin-top: -100px;
   margin-bottom: 100px;
}
.donut-inner h5 {
   margin-bottom: 5px;
   margin-top: 0;
}
.donut-inner span {
   font-size: 12px;
}

The output looks like this:

select table_name
from information_schema.columns
where COLUMN_NAME = 'MyColumn'

I know this question is 5 years old, but for anybody wondering how to do this without re-rendering the main page. This solution uses the dart editor/scripting language.

You could have an <object> tag that contains a data attribute. Make the <object> 1px by 1px and then use something like dart to dynamically change the <object>'s data attribute which re-renders the data in the 1px by 1px object.

HTML Script:

<object id="external_source" type="text/html" data="" width="1px" height="1px">
</object>

<button id="button1" type="button">Start Script</button>

<script async type="application/dart" src="dartScript.dart"></script>
<script async src="packages/browser/dart.js"></script>

someScript.php:

<?php
echo 'hello world';
?>

dartScript.dart:

import 'dart:html';

InputElement button1;
ObjectElement externalSource;

void main() {
    button1 = querySelector('#button1')
        ..onClick.listen(runExternalSource);

    externalSource = querySelector('#external_source');
}

void runExternalSource(Event e) {
    externalSource.setAttribute('data', 'someScript.php');
}

So long as you aren't posting any information and you are just looking to run a script, this should work just fine.

Just build the dart script using "pub Build(generate JS)" and then upload the package onto your server.

I've found this css (scss) solution that works quite well. On webkit browsers it shows the ellipsis and on other browsers it just truncates the text. Which is fine for my intended use.

$font-size: 26px;
$line-height: 1.4;
$lines-to-show: 3;

h2 {
  display: block; /* Fallback for non-webkit */
  display: -webkit-box;
  max-width: 400px;
  height: $font-size*$line-height*$lines-to-show; /* Fallback for non-webkit */
  margin: 0 auto;
  font-size: $font-size;
  line-height: $line-height;
  -webkit-line-clamp: $lines-to-show;
  -webkit-box-orient: vertical;
  overflow: hidden;
  text-overflow: ellipsis;
}

An example by the creator: http://codepen.io/martinwolf/pen/qlFdp

Range.EntireColumn

Yes! You can use Range.EntireColumn MSDN

dim column : column = 4

dim column_range : set column_range = Sheets(1).Cells(column).EntireColumn

Range("ColumnName:ColumnName")

If you were after a specific column, you could create a hard coded column range with the syntax e.g. Range("D:D").

However, I'd use entire column as it provides more flexibility to change that column at a later time.

Worksheet.Columns

Worksheet.Columns provides Range access to a column within a worksheet. MSDN

If you would like access to the first column of the first sheet. You would call the Columns function on the worksheet.

dim column_range: set column_range = Sheets(1).Columns(1)

The Columns property is also available on any Range MSDN

EntireRow can also be useful if you have a range for a single cell but would like to reach other cells on the row, akin to a LOOKUP

dim id : id = 12345


dim found : set found = Range("A:A").Find(id)

if not found is Nothing then
    'Get the fourth cell from the match
    MsgBox found.EntireRow.Cells(4)
end if

Try this one. It centers vertically and horizontally.

Center(
  child: Column(
    mainAxisAlignment: MainAxisAlignment.center,
    children: children,
  ),
)

well after spending about 10 days trying to solve this issue, i finally figured it out today and decide to post the solution

It's Work for me.

Add ?var1=data1&var2=data2 to the end of url to submit values to the page via GET:

using System.Net;
using System.IO;

string url = "https://www.example.com/scriptname.php?var1=hello";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream resStream = response.GetResponseStream();

If you have jest running as a script command, something like npm test, you need to use the following command to make it work:

npm test -- -t "fix order test"

1. Your call to MessageBox.Show needs to pass MessageBoxButtons.YesNo to get the Yes/No buttons instead of the OK button.

2. Compare the result of that call (which will block execution until the dialog returns) to DialogResult.Yes....

if (MessageBox.Show("Are you sure?", "Confirm", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{
    // user clicked yes
}
else
{
    // user clicked no
}

Just keep going with your code - you're on the right track:

//call SQL helper class to get initial data 
DataTable dt = sql.ExecuteDataTable("sp_MyProc");

dt.Columns.Add("NewColumn", typeof(System.Int32));

foreach(DataRow row in dt.Rows)
{
    //need to set value to NewColumn column

Since the back button is a function of the browser, it can be difficult to change the default functionality. There are some work arounds though. Take a look at this article:

http://www.irt.org/script/311.htm

Typically, the need to disable the back button is a good indicator of a programming issue/flaw. I would look for an alternative method like setting a session variable or a cookie that stores whether the form has already been submitted.

We can prove it mathematically which is something I was missing in the above answers.

It can dramatically help you understand how to calculate any method. I recommend reading it from top to bottom to fully understand how to do it:

1. T(n) = T(n-1) + 1 It means that the time it takes for the method to finish is equal to the same method but with n-1 which is T(n-1) and we now add + 1 because it's the time it takes for the general operations to be completed (except T(n-1)). Now, we are going to find T(n-1) as follow: T(n-1) = T(n-1-1) + 1. It looks like we can now form a function that can give us some sort of repetition so we can fully understand. We will place the right side of T(n-1) = ... instead of T(n-1) inside the method T(n) = ... which will give us: T(n) = T(n-1-1) + 1 + 1 which is T(n) = T(n-2) + 2 or in other words we need to find our missing k: T(n) = T(n-k) + k. The next step is to take n-k and claim that n-k = 1 because at the end of the recursion it will take exactly O(1) when n<=0. From this simple equation we now know that k = n - 1. Let's place k in our final method: T(n) = T(n-k) + k which will give us: T(n) = 1 + n - 1 which is exactly n or O(n).
2. Is the same as 1. You can test it your self and see that you get O(n).
3. T(n) = T(n/5) + 1 as before, the time for this method to finish equals to the time the same method but with n/5 which is why it is bounded to T(n/5). Let's find T(n/5) like in 1: T(n/5) = T(n/5/5) + 1 which is T(n/5) = T(n/5^2) + 1. Let's place T(n/5) inside T(n) for the final calculation: T(n) = T(n/5^k) + k. Again as before, n/5^k = 1 which is n = 5^k which is exactly as asking what in power of 5, will give us n, the answer is log5n = k (log of base 5). Let's place our findings in T(n) = T(n/5^k) + k as follow: T(n) = 1 + logn which is O(logn)
4. T(n) = 2T(n-1) + 1 what we have here is basically the same as before but this time we are invoking the method recursively 2 times thus we multiple it by 2. Let's find T(n-1) = 2T(n-1-1) + 1 which is T(n-1) = 2T(n-2) + 1. Our next place as before, let's place our finding: T(n) = 2(2T(n-2)) + 1 + 1 which is T(n) = 2^2T(n-2) + 2 that gives us T(n) = 2^kT(n-k) + k. Let's find k by claiming that n-k = 1 which is k = n - 1. Let's place k as follow: T(n) = 2^(n-1) + n - 1 which is roughly O(2^n)
5. T(n) = T(n-5) + n + 1 It's almost the same as 4 but now we add n because we have one for loop. Let's find T(n-5) = T(n-5-5) + n + 1 which is T(n-5) = T(n - 2*5) + n + 1. Let's place it: T(n) = T(n-2*5) + n + n + 1 + 1) which is T(n) = T(n-2*5) + 2n + 2) and for the k: T(n) = T(n-k*5) + kn + k) again: n-5k = 1 which is n = 5k + 1 that is roughly n = k. This will give us: T(n) = T(0) + n^2 + n which is roughly O(n^2).

I now recommend reading the rest of the answers which now, will give you a better perspective. Good luck winning those big O's :)

While you should certainly provide more information, if you are trying to go through each row, you can just iterate with a for loop:

import numpy
m = numpy.ones((3,5),dtype='int')
for row in m:
  print str(row)

In my case I have two activities. In the second activity I forgot to put super on the onCreate method.

super.onCreate(savedInstanceState);

I just encountered this exception and in my case it was cause by a white space between asp:content elements

So, this failed:

<asp:content runat="server" ContentPlaceHolderID="Header">
    Header
</asp:content>

<asp:Content runat="server" ContentPlaceHolderID="Content">
    Content
</asp:Content>

But removing the white spaces between the elements worked:

<asp:content runat="server" ContentPlaceHolderID="Header">
    Header
</asp:content><asp:Content runat="server" ContentPlaceHolderID="Content">
    Content
</asp:Content>

Once I'd discovered all the information of how my client was handling the encryption/decryption at their end it was straight forward using the AesManaged example suggested by dtb.

The finally implemented code started like this:

    try
    {
        // Create a new instance of the AesManaged class.  This generates a new key and initialization vector (IV).
        AesManaged myAes = new AesManaged();

        // Override the cipher mode, key and IV
        myAes.Mode = CipherMode.ECB;
        myAes.IV = new byte[16] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; // CRB mode uses an empty IV
        myAes.Key = CipherKey;  // Byte array representing the key
        myAes.Padding = PaddingMode.None;

        // Create a encryption object to perform the stream transform.
        ICryptoTransform encryptor = myAes.CreateEncryptor();

        // TODO: perform the encryption / decryption as required...

    }
    catch (Exception ex)
    {
        // TODO: Log the error 
        throw ex;
    }

ArrayList<Matrices> list = new ArrayList<Matrices>();
list.add( new Matrices(1,1,10) );
list.add( new Matrices(1,2,20) );

For people using swift [2.2] on Linux i.e. Ubuntu, the import is different!

The correct way to do this is to use Glibc. This is because on OS X and iOS, the basic Unix-like API's are in Darwin but in linux, these are located in Glibc. Importing Foundation won't help you here because it doesn't make the distinction by itself. To do this, you have to explicitly import it yourself:

#if os(macOS) || os(iOS)
import Darwin
#elseif os(Linux) || CYGWIN
import Glibc
#endif

You can follow the development of the Foundation framework here to learn more

EDIT: December 26th, 2018

As pointed out by @Cœur, starting from swift 3.0 some math functions are now part of the types themselves. For example, Double now has a squareRoot function. Similarly, ceil, floor, round, can all be achieved with Double.rounded(FloatingPointRoundingRule) -> Double.

Furthermore, I just downloaded and installed the latest stable version of swift on Ubuntu 18.04, and it looks like Foundation framework is all you need to import to have access to the math functions now. I tried finding documentation for this, but nothing came up.

? swift

tested and workes fine...

To "loop" and take advantage of Spark's parallel computation framework, you could define a custom function and use map.

def customFunction(row):

   return (row.name, row.age, row.city)

sample2 = sample.rdd.map(customFunction)

or

sample2 = sample.rdd.map(lambda x: (x.name, x.age, x.city))

The custom function would then be applied to every row of the dataframe. Note that sample2 will be a RDD, not a dataframe.

Map may be needed if you are going to perform more complex computations. If you just need to add a simple derived column, you can use the withColumn, with returns a dataframe.

sample3 = sample.withColumn('age2', sample.age + 2)

var IsPlainObject = function ( obj ) { return obj instanceof Object && ! ( obj instanceof Function || obj.toString( ) !== '[object Object]' || obj.constructor.name !== 'Object' ); },
    IsDOMObject = function ( obj ) { return obj instanceof EventTarget; },
    IsDOMElement = function ( obj ) { return obj instanceof Node; },
    IsListObject = function ( obj ) { return obj instanceof Array || obj instanceof NodeList; },

// In fact I am more likely t use these inline, but sometimes it is good to have these shortcuts for setup code

Following on from Richard's comment. Here's the easy way to convert your file to UNIX line endings. If you're like me you created it in Windows Notepad and then tried to run it in Linux - bad idea.

1. Download and install yourself a copy of Notepad++ (free).
2. Open your script file in Notepad++.
3. File menu -> Save As ->
4. Save as type: Unix script file (*.sh;*.bsh)
5. Copy the new .sh file to your Linux system
6. Maxe it executable with: chmod 755 the_script_filename
7. Run it with: ./the_script_filename

Any other problems try this link.

Both will have a key of 0, and that method of combining the arrays will collapse duplicates. Try using array_merge() instead.

$arr1 = array('foo'); // Same as array(0 => 'foo')
$arr2 = array('bar'); // Same as array(0 => 'bar')

// Will contain array('foo', 'bar');
$combined = array_merge($arr1, $arr2);

If the elements in your array used different keys, the + operator would be more appropriate.

$arr1 = array('one' => 'foo');
$arr2 = array('two' => 'bar');

// Will contain array('one' => 'foo', 'two' => 'bar');
$combined = $arr1 + $arr2;

Edit: Added a code snippet to clarify

Like the comments suggest, the solution is to use nested spans/rows.

<div class="container">
    <div class="row">
        <div class="span4">1</div>
        <div class="span8">
            <div class="row">
                <div class="span4">2</div>
                <div class="span4">3</div>
            </div>
            <div class="row">
                <div class="span4">4</div>
                <div class="span4">5</div>
            </div>
        </div>
    </div>
    <div class="row">
        <div class="span4">6</div>
        <div class="span4">7</div>
        <div class="span4">8</div>

My freeze on startup issue seemed to be related to the proxy settings. I saw the username\password dialog on startup, but Eclipse froze whenever I tried to click ok, cancel, or even just click away from the dialog. For a time, I was seeing this authentication pop-up with no freeze issue.

To fix it, I started eclipse using a different workspace, which thankfully didn't freeze on me. Then I went to Window --> Preferences --> General --> Network Connections. I edited my HTTP Proxy entry and unchecked "Requires Authentication". Then I started my original problematic workspace, which launched this time without freezing. Success!

I had no further issues when I re-opened my workspace, and was able to re-enable authentication without having a problem. I didn't see the username\password pop-up anymore on start-up, so there's a chance my authentication info was FUBAR at the time.

A much easier solution: Using a dynamic type

As of Json.NET 4.0 Release 1, there is native dynamic support. You don't need to declare a class, just use dynamic :

dynamic jsonDe = JsonConvert.DeserializeObject(json);

All the fields will be available:

foreach (string typeStr in jsonDe.Type[0])
{
    // Do something with typeStr
} 

string t = jsonDe.t;
bool a = jsonDe.a;
object[] data = jsonDe.data;
string[][] type = jsonDe.Type;

With dynamic you don't need to create a specific class to hold your data.

In some cases it might make more sense to process each selected item one at a time.

In other words, make a separate server call for each selected item passing the value of the selected item. In some cases the list will need to be processed as a whole, but in some not.

I needed to process a list of selected people and then have the results of the query show up on an existing page beneath the existing data for that person. I initially though of passing the whole list to the server, parsing the list, then passing back the data for all of the patients. I would have then needed to parse the returning data and insert it into the page in each of the appropriate places. Sending the request for the data one person at a time turned out to be much easier. Javascript for getting the selected items is described here: check if checkbox is checked javascript and jQuery for the same is described here: How to check whether a checkbox is checked in jQuery?.

For me the problem was my file encoding...I used powershell to write the xml file and this was not UTF-8 ... It seems that spring requires UTF8 because as soon as I changed the encoding (using notepad++) it works again without any errors

Now i Use in my powershellscript the following line to output the xml file in UTF-8: [IO.File]::WriteAllLines($fname_dataloader_xml_config_file, $dataloader_configfile)

instead of using the redirection operator > to create my file

Note: I didn't put any xml parameters in my beans tag and it works

Microsoft has the Windows Performance Toolkit.

It does require Windows Vista, Windows Server 2008, or Windows 7.

Use CTRL+D at each line and it will find the matching words and select them then you can use multiple cursors.

You can also use find to find all the occurrences and then it would be multiple cursors too.

Nesting of 'a' will not be possible. However if you badly want to keep the structure and still make it work like the way you want, then override the anchor tag click in javascript /jquery .

so you can have 2 event listeners for the two and control them accordingly.

Roll your own method

This is a generic approach for left padding anything. The concept is to use REPLICATE to create a version which is nothing but the padded value. Then concatenate it with the actual value, using a isnull/coalesce call if the data is NULLable. You now have a string that is double the target size to exactly the target length or somewhere in between. Now simply sheer off the N right-most characters and you have a left padded string.

SELECT RIGHT(REPLICATE('0', 2) + CAST(DATEPART(DAY, '2012-12-09') AS varchar(2)), 2) AS leftpadded_day

Go native

The CONVERT function offers various methods for obtaining pre-formatted dates. Format 103 specifies dd which means leading zero preserved so all that one needs to do is slice out the first 2 characters.

SELECT CONVERT(char(2), CAST('2012-12-09' AS datetime), 103) AS convert_day

            break;
        case KeyEvent.VK_DOWN:
            // handle down 
            break;
        case KeyEvent.VK_LEFT:
            // handle left
            break;
        case KeyEvent.VK_RIGHT :

m2e is only included in the Java developer version of Eclipse, as you can see on this page ("Maven" topic): http://www.eclipse.org/downloads/compare.php

However, an easy way to get m2e is through the Eclipse Marketplace:

Go to Help -> Eclipse Marketplace and look for m2e. Click "Maven Integration for Eclipse", then on Install (or drag and drop the install link to your running Eclipse workspace if you opened the marketplace in a browser), et voila!

Along with the points made by others, the $= selector is the "ends with" selector. You will want the *= (contains) selector, like so:

$('a').each(function() {
    if ($(this).is('[href*="?"')) {
        alert("Contains questionmark");
    }
});

Here's a live demo ->

As noted by Matt Ball, unless you will need to also manipulate links without a question mark (which may be the case, since you say your example is simplified), it would be less code and much faster to simply select only the links you want to begin with:

$('a[href*="?"]').each(function() {
    alert("Contains questionmark");
});

I had similar problem with IntelliJ when tried to run some Groovy scripts. Here is how I solved it.

Go to "Project Structure"-> "Project" -> "Project language level" and select "SDK default". This should use the same SDK for all project modules.

Try to use 3rd party tool, such as SQL Data Examiner which compares Oracle databases and shows you differences.

System.String is a reference type and already "nullable".

Nullable<T> and the ? suffix are for value types such as Int32, Double, DateTime, etc.

object["property"] = value;

or

object.property = value;

Object and Array in JavaScript are different in terms of usage. Its best if you understand them:

Object vs Array: JavaScript

Take a look here: https://reacttraining.com/react-router/core/api/Route/exact-bool

exact: bool

When true, will only match if the path matches the location.pathname exactly.

**path**    **location.pathname**   **exact**   **matches?**

/one        /one/two                true        no
/one        /one/two                false       yes

Newtonsoft.JSON is a good solution for these kind of situations. Also Newtonsof.JSON is faster than others, such as JavaScriptSerializer, DataContractJsonSerializer.

In this sample, you can the following:

var jsonData = JObject.Parse("your JSON data here");

Then you can cast jsonData to JArray, and you can use a for loop to get data at each iteration.

Also, I want to add something:

for (int i = 0; (JArray)jsonData["data"].Count; i++)
{
    var data = jsonData[i - 1];
}

Working with dynamic object and using Newtonsoft serialize is a good choice.

Most code I've seen is camelCase functions (lower case initial letter), and ProperCase/PascalCase class names, and (most usually), snake_case variables.

But, to be honest, this is all just guidance. The single most important thing is to be consistent across your code base. Pick what seems natural / works for you, and stick to it. If you're joining a project in progress, follow their standards.

Your best option will probably be to adjust the top padding & compare across browsers. It's not perfect, but I think it's as close as you can get.

padding-top:4px;

The amount of padding you need will depend on the font size.

Tip: If your font is set in px, set padding in px as well. If your font is set in em, set the padding in em too.

EDIT

These are the options I think you have, since vertical-align isn't consistant across the browsers.

A. Remove height attribute and let the browser handle it. This usually works the best for me.

 <style>
    select{
        border: 1px solid #ABADB3;
        margin: 0;
        padding: auto 0;
        font-size:14px;
    }
    </style>
    <select>
        <option>option 1</option>
        <option>number 2</option>
    </select>

B. Add top-padding to push down the text. (Pushed down the arrow in some browsers)

<style>
select{
    height: 28px !important;
    border: 1px solid #ABADB3;
    margin: 0;
    padding: 4px 0 0 0;
    font-size:14px;
}
</style>
<select>
    <option>option 1</option>
    <option>number 2</option>
</select>

C. You can make the font larger to try and match the select height a little nicer.

You want to look at CodeDOM. It allows defining code elements and compiling them. Quoting MSDN:

...This object graph can be rendered as source code using a CodeDOM code generator for a supported programming language. The CodeDOM can also be used to compile source code into a binary assembly.

In my case I am running 3 nodes in VM's by using Hyper-V. By using the following steps I was able to "restart" the cluster after restarting all VM's.

1. (Optional) Swap off

   $ swapoff -a

2. You have to restart all Docker containers

   $ docker restart $(docker ps -a -q)

3. Check the nodes status after you performed step 1 and 2 on all nodes (the status is NotReady)

   $ kubectl get nodes

4. Restart the node

   $ systemctl restart kubelet

5. Check again the status (now should be in Ready status)

Note: I do not know if it does metter the order of nodes restarting, but I choose to start with the k8s master node and after with the minions. Also it will take a little bit to change the node state from NotReady to Ready

Just call the "type" built in using three parameters, like this:

ClassName = type("ClassName", (Base1, Base2,...), classdictionary)

update as stated in the comment bellow this is not the answer to this question at all. I will keep it undeleted, since there are hints some people get here trying to dynamically create classes - which is what the line above does.

To create an object of a class one has a reference too, as put in the accepted answer, one just have to call the class:

instance = ClassObject()

The mechanism for instantiation is thus:

Python does not use the new keyword some languages use - instead it's data model explains the mechanism used to create an instantance of a class when it is called with the same syntax as any other callable:

Its class' __call__ method is invoked (in the case of a class, its class is the "metaclass" - which is usually the built-in type). The normal behavior of this call is to invoke the (pseudo) static __new__ method on the class being instantiated, followed by its __init__. The __new__ method is responsible for allocating memory and such, and normally is done by the __new__ of object which is the class hierarchy root.

So calling ClassObject() invokes ClassObject.__class__.call() (which normally will be type.__call__) this __call__ method will receive ClassObject itself as the first parameter - a Pure Python implementation would be like this: (the cPython version is of course, done in C, and with lots of extra code for cornercases and optimizations)

class type:
    ...
    def __call__(cls, *args, **kw):
          constructor = getattr(cls, "__new__")
          instance = constructor(cls) if constructor is object.__new__ else constructor(cls, *args, **kw)
          instance.__init__(cls, *args, **kw)
          return instance

(I don't recall seeing on the docs the exact justification (or mechanism) for suppressing extra parameters to the root __new__ and passing it to other classes - but it is what happen "in real life" - if object.__new__ is called with any extra parameters it raises a type error - however, any custom implementation of a __new__ will get the extra parameters normally)

public void onClick1(View v) {
  DatePickerDialog dialog = new DatePickerDialog(this, this, 2013, 2, 18);
  dialog.show();
}

public void onDateSet1(DatePicker view, int year1, int month1, int day1) {
  e1.setText(day1 + "/" + (month1+1) + "/" + year1);
}

In PowerShell, you could set the http_proxy and https_proxy environment variables like so:

$env:http_proxy="http://proxy:3128"
$env:https_proxy="http://proxy:3128"

Getting the last item of an array can be achieved by using the slice method with negative values.

You can read more about it here at the bottom.

var fileName = loc_array.slice(-1)[0];
if(fileName.toLowerCase() == "index.html")
{
  //your code...
}

Using pop() will change your array, which is not always a good idea.

An alternative would be to use Font-Awesome for icons:

Including Font-Awesome

Open Font-Awesome on CDNJS and copy the CSS url of the latest version:

<link rel="stylesheet" href="<url>">

Or in CSS

@import url("<url>");

For example (note, the version will change):

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.css">

Usage:

<i class="fa fa-bed"></i>

It contains a lot of icons!

We also have same problem with phonegap application tested in chrome. One windows machine we use below batch file everyday before Opening Chrome. Remember before running this you need to clean all instance of chrome from task manager or you can select chrome to not to run in background.

BATCH: (use cmd)

cd D:\Program Files (x86)\Google\Chrome\Application\chrome.exe --disable-web-security

val() is more like a shortcut for attr('value'). For your usage use text() or html() instead

No, it is not valid. But a "solution" can be creating a modal window outside of form "a" containing the form "b".

<div id="myModalFormB" class="modal">
    <form action="b">
        <input.../>
        <input.../>
        <input.../>
        <button type="submit">Save</button>
    </form>
</div>

<form action="a">
    <input.../>
    <a href="#myModalFormB">Open modal b </a>
    <input.../>
</form>

It can be easily done if you are using bootstrap or materialize css. I'm doing this to avoid using iframe.

The loopj library can be used straight-forward for this purpose:

SyncHttpClient client = new SyncHttpClient();
RequestParams params = new RequestParams();
params.put("text", "some string");
params.put("image", new File(imagePath));

client.post("http://example.com", params, new TextHttpResponseHandler() {
  @Override
  public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
    // error handling
  }

  @Override
  public void onSuccess(int statusCode, Header[] headers, String responseString) {
    // success
  }
});

http://loopj.com/

This line of code might not work in IE 8 because of native support problems.

$(".hidden").attr("placeholder", "Type here to search");

You can try importing a JQuery placeholder plugin for this task. Simply import it to your libraries and initiate from the sample code below.

$('input, textarea').placeholder();

Don't pass db models directly to your views. You're lucky enough to be using MVC, so encapsulate using view models.

Create a view model class like this:

public class EmployeeAddViewModel
{
    public Employee employee { get; set; }
    public Dictionary<int, string> staffTypes { get; set; }
    // really? a 1-to-many for genders
    public Dictionary<int, string> genderTypes { get; set; }

    public EmployeeAddViewModel() { }
    public EmployeeAddViewModel(int id)
    {
        employee = someEntityContext.Employees
            .Where(e => e.ID == id).SingleOrDefault();

        // instantiate your dictionaries

        foreach(var staffType in someEntityContext.StaffTypes)
        {
            staffTypes.Add(staffType.ID, staffType.Type);
        }

        // repeat similar loop for gender types
    }
}

Controller:

[HttpGet]
public ActionResult Add()
{
    return View(new EmployeeAddViewModel());
}

[HttpPost]
public ActionResult Add(EmployeeAddViewModel vm)
{
    if(ModelState.IsValid)
    {
        Employee.Add(vm.Employee);
        return View("Index"); // or wherever you go after successful add
    }

    return View(vm);
}

Then, finally in your view (which you can use Visual Studio to scaffold it first), change the inherited type to ShadowVenue.Models.EmployeeAddViewModel. Also, where the drop down lists go, use:

@Html.DropDownListFor(model => model.employee.staffTypeID,
    new SelectList(model.staffTypes, "ID", "Type"))

and similarly for the gender dropdown

@Html.DropDownListFor(model => model.employee.genderID,
    new SelectList(model.genderTypes, "ID", "Gender"))

Update per comments

For gender, you could also do this if you can be without the genderTypes in the above suggested view model (though, on second thought, maybe I'd generate this server side in the view model as IEnumerable). So, in place of new SelectList... below, you would use your IEnumerable.

@Html.DropDownListFor(model => model.employee.genderID,
    new SelectList(new SelectList()
    {
        new { ID = 1, Gender = "Male" },
        new { ID = 2, Gender = "Female" }
    }, "ID", "Gender"))

Finally, another option is a Lookup table. Basically, you keep key-value pairs associated with a Lookup type. One example of a type may be gender, while another may be State, etc. I like to structure mine like this:

ID | LookupType | LookupKey | LookupValue | LookupDescription | Active
1  | Gender     | 1         | Male        | male gender       | 1
2  | State      | 50        | Hawaii      | 50th state        | 1
3  | Gender     | 2         | Female      | female gender     | 1
4  | State      | 49        | Alaska      | 49th state        | 1
5  | OrderType  | 1         | Web         | online order      | 1

I like to use these tables when a set of data doesn't change very often, but still needs to be enumerated from time to time.

Hope this helps!

If A1 has the week number and year as a 3 or 4 digit integer in the format wwYY then the formula would be:

=INT(A1/100)*7+DATE(MOD([A1,100),1,1)-WEEKDAY(DATE(MOD(A1,100),1,1))-5

the subtraction of the weekday ensures you return a consistent start day of the week. Use the final subtraction to adjust the start day.

Use current_url element for Python 2:

print browser.current_url

For Python 3 and later versions of selenium:

print(driver.current_url)

You can use commercial tools like Sisulizer. It will create satellite assembly for each language. Only thing you should pay attention is not to obfuscate form class names (if you use obfuscator).

Callbacks in C are usually implemented using function pointers and an associated data pointer. You pass your function on_event() and data pointers to a framework function watch_events() (for example). When an event happens, your function is called with your data and some event-specific data.

Callbacks are also used in GUI programming. The GTK+ tutorial has a nice section on the theory of signals and callbacks.

IMHO the best option is to use YAML's native block scalars. Specifically in this case, the folded style block.

By invoking sh -c you can pass arguments to your container as commands, but if you want to elegantly separate them with newlines, you'd want to use the folded style block, so that YAML will know to convert newlines to whitespaces, effectively concatenating the commands.

A full working example:

apiVersion: v1
kind: Pod
metadata:
  name: myapp
  labels:
    app: myapp
spec:
  containers:
  - name: busy
    image: busybox:1.28
    command: ["/bin/sh", "-c"]
    args:
    - >
      command_1 &&
      command_2 &&
      ... 
      command_n

You are asking to initialize four variables using a single float object, which of course is not iterable. You can do -

1. grade_1, grade_2, grade_3, grade_4 = [0.0 for _ in range(4)]
2. grade_1 = grade_2 = grade_3 = grade_4 = 0.0

Unless you want to initialize them with different values of course.

Returning pure array is slightly faster than returning an array of objects.

Why not use a library function to validate the ip address?

>>> ip="241.1.1.112343434" 
>>> socket.inet_aton(ip)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
socket.error: illegal IP address string passed to inet_aton

Do attributes migrated from parent to child help identify¹ the child?

• If yes: the identification-dependence exists, the relationship is identifying and the child entity is "weak".
• If not: the identification-dependence doesn't exists, the relationship is non-identifying and the child entity "strong".

Note that identification-dependence implies existence-dependence, but not the other way around. Every non-NULL FK means a child cannot exist without parent, but that alone doesn't make the relationship identifying.

For more on this (and some examples), take a look at the "Identifying Relationships" section of the ERwin Methods Guide.

P.S. I realize I'm (extremely) late to the party, but I feel other answers are either not entirely accurate (defining it in terms of existence-dependence instead of identification-dependence), or somewhat meandering. Hopefully this answer provides more clarity...

¹ The child's FK is a part of child's PRIMARY KEY or (non-NULL) UNIQUE constraint.

In my case, the issue was that I had another element in the center of the div with a conflicting z-index.

.wrapper {_x000D_
  color: white;_x000D_
  width: 320px;_x000D_
  position: relative;_x000D_

  right: 0;_x000D_
  /* This z-index override is needed to display on top of the other_x000D_
     div. Or, just swap the order of the HTML tags. */_x000D_
  z-index: 1;_x000D_
}_x000D_
_x000D_
.child {_x000D_
  background: green;_x000D_
}_x000D_
_x000D_
.conflicting {_x000D_
  position: absolute;_x000D_
  left: 120px;_x000D_
  height: 40px;_x000D_
  background: red;_x000D_
  margin: 0 auto;_x000D_
}

<div class="wrapper">_x000D_
  <div class="parent">_x000D_
    <div class="child">_x000D_
       Centered_x000D_
    </div>_x000D_
  </div>_x000D_
  <div class="conflicting">_x000D_
    Conflicting_x000D_
  </div>_x000D_
</div>

You could have a div for the top with one background and another for the main page, and seperate the page content between them or put the content in a floating div on another z-level. The way you are doing it may work but I doubt it will work across every browser you encounter.

Pay attention: you cannot install arbitrary versions of tensorflow, they have to correspond to your python installation, which isn't conveyed by most of the answers here. This is also true for the current wheels like https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-1.1.0-cp35-cp35m-win_amd64.whl (from this answer above). For this example, the cp35-cp35m hints that it is for Python 3.5.x

A huge list of different wheels/compatibilities can be found here on github. By using this, you can downgrade to almost every availale version in combination with the respective for python. For example:

pip install tensorflow==2.0.0

(note that previous to installing Python 3.7.8 alongside version 3.8.3 in my case, you would get

ERROR: Could not find a version that satisfies the requirement tensorflow==2.0.0 (from versions: 2.2.0rc1, 2.2.0rc2, 2.2.0rc3, 2.2.0rc4, 2.2.0, 2.3.0rc0, 2.3.0rc1)
ERROR: No matching distribution found for tensorflow==2.0.0

this also holds true for other non-compatible combinations.)

This should also be useful for legacy CPU without AVX support or GPUs with a compute capability that's too low.

If you only need the most recent releases (which it doesn't sound like in your question) a list of urls for the current wheel packages is available on this tensorflow page. That's from this SO-answer.

Note: This link to a list of different versions didn't work for me.

For anyone having issues with this on https://forge.laravel.com, I managed to get this to work using a compilation of SO answers;

You will need the sudo password.

I am too late but let me explain how I solved this problem.

This problem is basically because of improper folders/solution structure.

this issue may occur because 1. If you have copied project from other location and trying to run the project.

so to resolve this go to original location and crosscheck the folders and files again.

this works for me.

Use slidedown():

$("test").slideDown("slow");

You can use parseInt() but, as mentioned, the radix (base) should be specified:

x = parseInt(x, 10);
y = parseInt(y, 10);

10 means a base-10 number.

See this link for an explanation of why the radix is necessary.

Enter while securing an area dynamically

E.G.

char *inputString(FILE* fp, size_t size){
//The size is extended by the input with the value of the provisional
    char *str;
    int ch;
    size_t len = 0;
    str = realloc(NULL, sizeof(*str)*size);//size is start size
    if(!str)return str;
    while(EOF!=(ch=fgetc(fp)) && ch != '\n'){
        str[len++]=ch;
        if(len==size){
            str = realloc(str, sizeof(*str)*(size+=16));

end

In case of Oracle since 12c you have DEFAULT ON NULL which implies a NOT NULL constraint.

ALTER TABLE tbl ADD (col VARCHAR(20) DEFAULT ON NULL 'MyDefault');

ALTER TABLE

ON NULL

If you specify the ON NULL clause, then Oracle Database assigns the DEFAULT column value when a subsequent INSERT statement attempts to assign a value that evaluates to NULL.

When you specify ON NULL, the NOT NULL constraint and NOT DEFERRABLE constraint state are implicitly specified. If you specify an inline constraint that conflicts with NOT NULL and NOT DEFERRABLE, then an error is raised.

All the symptoms you describe suggest that you never tell MySQL what time zone to use so it defaults to system's zone. Think about it: if all it has is '2011-03-13 02:49:10', how can it guess that it's a local Tanzanian date?

As far as I know, MySQL doesn't provide any syntax to specify time zone information in dates. You have to change it a per-connection basis; something like:

SET time_zone = 'EAT';

If this doesn't work (to use named zones you need that the server has been configured to do so and it's often not the case) you can use UTC offsets because Tanzania does not observe daylight saving time at the time of writing but of course it isn't the best option:

SET time_zone = '+03:00';

>>> import subprocess
>>> cmd = [ 'echo', 'arg1', 'arg2' ]
>>> output = subprocess.Popen( cmd, stdout=subprocess.PIPE ).communicate()[0]
>>> print output
arg1 arg2

>>> 

There is a bug in using of the subprocess.PIPE. For the huge output use this:

import subprocess
import tempfile

with tempfile.TemporaryFile() as tempf:
    proc = subprocess.Popen(['echo', 'a', 'b'], stdout=tempf)
    proc.wait()
    tempf.seek(0)
    print tempf.read()

This code works. I have a date input field that has been set to read only which forces the user to select from the calendar.

for a start date:

var updateInput = "var input = document.getElementById('startDateInput');" +
    "input.value = '18-Jan-2016';" +
    "angular.element(input).scope().$apply(function(s) { s.$parent..searchForm[input.name].$setViewValue(input.value);})";
browser.executeScript(updateInput);

for an end date:

var updateInput = "var input = document.getElementById('endDateInput');" +
    "input.value = '22-Jan-2016';" +
    "angular.element(input).scope().$apply(function(s) { s.$parent.searchForm[input.name].$setViewValue(input.value);})";
    browser.executeScript(updateInput);

It sounds like you're trying to link with your resulting object file with gcc instead of g++:

Note that programs using C++ object files must always be linked with g++, in order to supply the appropriate C++ libraries. Attempting to link a C++ object file with the C compiler gcc will cause "undefined reference" errors for C++ standard library functions:

$ g++ -Wall -c hello.cc
$ gcc hello.o       (should use g++)
hello.o: In function `main':
hello.o(.text+0x1b): undefined reference to `std::cout'
.....
hello.o(.eh_frame+0x11):
  undefined reference to `__gxx_personality_v0'

I'd like to add a correction/update to the bit about $HOME taking precedence. The home directory in /etc/passwd takes precedence over everything.

I'm a long time Cygwin user and I just did a clean install of Windows 7 x64 and Cygwin V1.126. I was going nuts trying to figure out why every time I ran ssh I kept getting:

e:\>ssh foo.bar.com
Could not create directory '/home/dhaynes/.ssh'.
The authenticity of host 'foo.bar.com (10.66.19.19)' can't be established.
...

I add the HOME=c:\users\dhaynes definition in the Windows environment but still it kept trying to create '/home/dhaynes'. I tried every combo I could including setting HOME to /cygdrive/c/users/dhaynes. Googled for the error message, could not find anything, couldn't find anything on the cygwin site. I use cygwin from cmd.exe, not bash.exe but the problem was present in both.

I finally realized that the home directory in /etc/passwd was taking precedence over the $HOME environment variable. I simple re-ran 'mkpasswd -l >/etc/passwd' and that updated the home directory, now all is well with ssh.

That may be obvious to linux types with sysadmin experience but for those of us who primarily use Windows it's a bit obscure.

Since OP asked for best practices, I think we're still missing some good advices here.

A single helpers.php file is far from a good practice. Firstly because you mix a lot of different kind of functions, so you're against the good coding principles. Moreover, this could hurt not only the code documentation but also the code metrics like Cyclomatic Complexity, Maintainability Index and Halstead Volume. The more functions you have the more it gets worse.

Code documentation would be Ok using tools like phpDocumentor, but using Sami it won't render procedural files. Laravel API documentation is such a case - there's no helper functions documentation: https://laravel.com/api/5.4

Code metrics can be analyzed with tools like PhpMetrics. Using PhpMetrics version 1.x to analyze Laravel 5.4 framework code will give you very bad CC/MI/HV metrics for both src/Illuminate/Foundation/helpers.php and src/Illuminate/Support/helpers.php files.

Multiple contextual helper files (eg. string_helpers.php, array_helpers.php, etc.) would certainly improve those bad metrics resulting in an easier code to mantain. Depending on the code documentation generator used this would be good enough.

It can be further improved by using helper classes with static methods so they can be contextualized using namespaces. Just like how Laravel already does with Illuminate\Support\Str and Illuminate\Support\Arr classes. This improves both code metrics/organization and documentation. Class aliases could be used to make them easier to use.

Structuring with classes makes the code organization and documentation better but on the other hand we end up loosing those great short and easy to remember global functions. We can further improve that approach by creating function aliases to those static classes methods. This can be done either manually or dynamically.

Laravel internally use the first approach by declaring functions in the procedural helper files that maps to the static classes methods. This might be not the ideal thing as you need to redeclare all the stuff (docblocks/arguments).
I personally use a dynamic approach with a HelperServiceProvider class that create those functions in the execution time:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class HelperServiceProvider extends ServiceProvider
{
    /**
     * The helper mappings for the application.
     *
     * @var array
     */
    protected $helpers = [
        'uppercase' => 'App\Support\Helpers\StringHelper::uppercase',
        'lowercase' => 'App\Support\Helpers\StringHelper::lowercase',
    ];

    /**
     * Bootstrap the application helpers.
     *
     * @return void
     */
    public function boot()
    {
        foreach ($this->helpers as $alias => $method) {
            if (!function_exists($alias)) {
                eval("function {$alias}(...\$args) { return {$method}(...\$args); }");
            }
        }
    }

    /**
     * Register the service provider.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

One can say this is over engineering but I don't think so. It works pretty well and contrary to what might be expected it does not cost relevant execution time at least when using PHP 7.x.

I started to save this as a function, and call it as needed for whatever reactions require it:

function Remove(){
    while(scene.children.length > 0){ 
    scene.remove(scene.children[0]); 
}
}

Now you can call the Remove(); function where appropriate.

In order an element to appear in front of another you have to give higher z-index to the front element, and lower z-index to the back element, also you should indicate position: absolute/fixed...

Example:

<div style="z-index:100; position: fixed;">Hello</div>
<div style="z-index: -1;">World</div>

You can save a string raw as is by using FileReader.

Save the string in a blob and call readAsArrayBuffer(). Then the onload-event results an arraybuffer, which can converted in a Uint8Array. Unfortunately this call is asynchronous.

This little function will help you:

function stringToBytes(str)
{
    let reader = new FileReader();
    let done = () => {};

    reader.onload = event =>
    {
        done(new Uint8Array(event.target.result), str);
    };
    reader.readAsArrayBuffer(new Blob([str], { type: "application/octet-stream" }));

    return { done: callback => { done = callback; } };
}

Call it like this:

stringToBytes("\u{1f4a9}").done(bytes =>
{
    console.log(bytes);
});

output: [240, 159, 146, 169]

explanation:

JavaScript use UTF-16 and surrogate-pairs to store unicode characters in memory. To save unicode character in raw binary byte streams an encoding is necessary. Usually and in the most case, UTF-8 is used for this. If you not use an enconding you can't save unicode character, just ASCII up to 0x7f.

FileReader.readAsArrayBuffer() uses UTF-8.

XmlWriter is the fastest way to write good XML. XDocument, XMLDocument and some others works good aswell, but are not optimized for writing XML. If you want to write the XML as fast as possible, you should definitely use XmlWriter.

SQL ad hoc query abilities are enough of a reason for me. With a good schema and indexing on the tables, this is fast and effective and will have good performance.

You just need a binary (with debugging symbols included) that is identical to the one that generated the core dump file. Then you can run gdb path/to/the/binary path/to/the/core/dump/file to debug it.

When it starts up, you can use bt (for backtrace) to get a stack trace from the time of the crash. In the backtrace, each function invocation is given a number. You can use frame number (replacing number with the corresponding number in the stack trace) to select a particular stack frame.

You can then use list to see code around that function, and info locals to see the local variables. You can also use print name_of_variable (replacing "name_of_variable" with a variable name) to see its value.

Typing help within GDB will give you a prompt that will let you see additional commands.

The check can be made easier with diff:

diff <(ssh-keygen -y -f $private_key_file) $public_key_file

The only odd thing is that diff says nothing if the files are the same, so you'll only be told if the public and private don't match.

You are asking two separate questions here:

What's the maximum length of an HTTP GET request?

As already mentioned, HTTP itself doesn't impose any hard-coded limit on request length; but browsers have limits ranging on the 2 KB - 8 KB (255 bytes if we count very old browsers).

Is there a response error defined that the server can/should return if it receives a GET request exceeds this length?

That's the one nobody has answered.

HTTP 1.1 defines status code 414 Request-URI Too Long for the cases where a server-defined limit is reached. You can see further details on RFC 2616.

For the case of client-defined limits, there isn't any sense on the server returning something, because the server won't receive the request at all.

This is not ideal as it removes all, but might work for your needs:

z = document.querySelector('video');
z.parentNode.replaceChild(z.cloneNode(1), z);

Cloning a node copies all of its attributes and their values, including intrinsic (in–line) listeners. It does not copy event listeners added using addEventListener()

Node.cloneNode()

I found it was impossible to assign a layout to the centralwidget until I had added at least one child beneath it. Then I could highlight the tiny icon with the red 'disabled' mark and then click on a layout in the Designer toolbar at top.

If you return a FileResult from your action method, and use the File() extension method on the controller, doing what you want is pretty easy. There are overrides on the File() method that will take the binary contents of the file, the path to the file, or a Stream.

public FileResult DownloadFile()
{
    return File("path\\to\\pdf.pdf", "application/pdf");
}

I have some issues to setup it in a Vagrant machine. Whats really works for me was execute a:

chmod -R o+w app/storage/

from inside the Vagrant machine.

My initial guess would be that the Java SDK is for building the JVM while the JDK is for building apps for the JVM.

Edit: Although this looks to be incorrect at the moment. Sun are in the process of opensourcing the JVM (perhaps they've even finished, now) so I wouldn't be too surprised if my answer does become correct... But at the moment, the SDK and JDK are the same thing.

I was working on something like this. But is working only with structures generated from proto. https://github.com/flowup-labs/grpc-utils

in your proto

message Msg {
  Firstname string = 1 [(gogoproto.jsontag) = "name.firstname"];
  PseudoFirstname string = 2 [(gogoproto.jsontag) = "lastname"];
  EmbedMsg = 3  [(gogoproto.nullable) = false, (gogoproto.embed) = true];
  Lastname string = 4 [(gogoproto.jsontag) = "name.lastname"];
  Inside string  = 5 [(gogoproto.jsontag) = "name.inside.a.b.c"];
}

message EmbedMsg{
   Opt1 string = 1 [(gogoproto.jsontag) = "opt1"];
}

Then your output will be

{
"lastname": "Three",
"name": {
    "firstname": "One",
    "inside": {
        "a": {
            "b": {
                "c": "goo"
            }
        }
    },
    "lastname": "Two"
},
"opt1": "var"
}

Hey there, this works for me (I couldn't get this working with the Google API links you were using):

I believe the correct answer is actually a combination of both approaches: viewWIllTransition(toSize:) and NotificationCenter's UIDeviceOrientationDidChange.

viewWillTransition(toSize:) notifies you before the transition.

NotificationCenter UIDeviceOrientationDidChange notifies you after.

You have to be very careful. For example, in UISplitViewController when the device rotates into certain orientations, the DetailViewController gets popped off the UISplitViewController's viewcontrollers array, and pushed onto the master's UINavigationController. If you go searching for the detail view controller before the rotation has finished, it may not exist and crash.

Sometimes deleting the .lock file does not work. You can try this:

Remove RECENT_WORKSPACES line from eclipse/configuration/.settings/org.eclipse.ui.ide.prefs

We copy/paste html pages from our ERP to Excel using "paste special.. as html/unicode" and it works quite well with tables.

@eljenso : intrafest-servlet.xml webapplication context xml will be used if the application uses SPRING WEB MVC.

Otherwise the @kosoant configuration is fine.

Simple example if you dont use SPRING WEB MVC, but want to utitlize SPRING IOC :

In web.xml:

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:application-context.xml</param-value>
</context-param>

Then, your application-context.xml will contain: <import resource="foo-services.xml"/> these import statements to load various application context files and put into main application-context.xml.

Thanks and hope this helps.

Getting JMX through the Firewall is really hard. The Problem is that standard RMI uses a second random assigned port (beside the RMI registry).

We have three solution that work, but every case needs a different one:

1. JMX over SSH Tunnel with Socks proxy, uses standard RMI with SSH magic http://simplygenius.com/2010/08/jconsole-via-socks-ssh-tunnel.html

2. JMX MP (alternative to standard RMI), uses only one fixed port, but needs a special jar on server and client http://meteatamel.wordpress.com/2012/02/13/jmx-rmi-vs-jmxmp/

3. Start JMX Server form code, there it is possible to use standard RMI and use a fixed second port: https://issues.apache.org/bugzilla/show_bug.cgi?id=39055

As long as your array $phpinfo['PHP Core']['memory_limit'] contains the value of memory_limit, it does work the following:

• The last character of that value can signal the shorthand notation. If it's an invalid one, it's ignored.
• The beginning of the string is converted to a number in PHP's own specific way: Whitespace ignored etc.
• The text between the number and the shorthand notation (if any) is ignored.

Example:

# Memory Limit equal or higher than 64M?
$ok = (int) (bool) setting_to_bytes($phpinfo['PHP Core']['memory_limit']) >= 0x4000000;

/**
 * @param string $setting
 *
 * @return NULL|number
 */
function setting_to_bytes($setting)
{
    static $short = array('k' => 0x400,
                          'm' => 0x100000,
                          'g' => 0x40000000);

    $setting = (string)$setting;
    if (!($len = strlen($setting))) return NULL;
    $last    = strtolower($setting[$len - 1]);
    $numeric = (int) $setting;
    $numeric *= isset($short[$last]) ? $short[$last] : 1;
    return $numeric;
}

Details of the shorthand notation are outline in a PHP manual's FAQ entry and extreme details are part of Protocol of some PHP Memory Stretching Fun.

Take care if the setting is -1 PHP won't limit here, but the system does. So you need to decide how the installer treats that value.

If you are working with ActionBarSherlock

In your theme add this:

<style name="MyTheme" parent="Theme.Sherlock">
    ....
    <item name="windowContentOverlay">@null</item>
    <item name="android:windowContentOverlay">@null</item>
    ....
</style>

You wrote """I assume that means the HTML contains some wrongly-formed attempt at unicode somewhere."""

The HTML is NOT expected to contain any kind of "attempt at unicode", well-formed or not. It must of necessity contain Unicode characters encoded in some encoding, which is usually supplied up front ... look for "charset".

You appear to be assuming that the charset is UTF-8 ... on what grounds? The "\xA0" byte that is shown in your error message indicates that you may have a single-byte charset e.g. cp1252.

If you can't get any sense out of the declaration at the start of the HTML, try using chardet to find out what the likely encoding is.

Why have you tagged your question with "regex"?

Update after you replaced your whole question with a non-question:

html = urllib.urlopen(link).read()
# html refers to a str object. To get unicode, you need to find out
# how it is encoded, and decode it.

html.encode("utf8","ignore")
# problem 1: will fail because html is a str object;
# encode works on unicode objects so Python tries to decode it using 
# 'ascii' and fails
# problem 2: even if it worked, the result will be ignored; it doesn't 
# update html in situ, it returns a function result.
# problem 3: "ignore" with UTF-n: any valid unicode object 
# should be encodable in UTF-n; error implies end of the world,
# don't try to ignore it. Don't just whack in "ignore" willy-nilly,
# put it in only with a comment explaining your very cogent reasons for doing so.
# "ignore" with most other encodings: error implies that you are mistaken
# in your choice of encoding -- same advice as for UTF-n :-)
# "ignore" with decode latin1 aka iso-8859-1: error implies end of the world.
# Irrespective of error or not, you are probably mistaken
# (needing e.g. cp1252 or even cp850 instead) ;-)

Got similar issue. Did following steps, issue resolved:

1. Remove project in eclipse.
2. Delete .Project file and . Settings folder.
3. Import project as existing maven project again to eclipse.

try using:

RAISERROR('your message here!!!',0,1) WITH NOWAIT

you could also try switching to "Results to Text" it is just a few icons to the right of "Execute" on the default tool bar.

With both of the above in place, and you still you do not see the messages, make sure you are running the same server/database/owner version of the procedure that you are editing. Make sure you are hitting the RAISERROR command, make it the first command inside the procedure.

If all else fails, you could create a table:

create table temp_log (RowID int identity(1,1) primary key not null
                      , MessageValue varchar(255))

then:

INSERT INTO temp_log VALUES ('Your message here')

then after running the procedure (provided no rollbacks) just select the table.

For me this worked in a vagrant VM:

sudo /usr/bin/passwd root <<EOF
12345678
12345678
EOF

Use -e or --env value to set environment variables (default []).

An example from a startup script:

 docker run  -e myhost='localhost' -it busybox sh

If you want to use multiple environments from the command line then before every environment variable use the -e flag.

Example:

 sudo docker run -d -t -i -e NAMESPACE='staging' -e PASSWORD='foo' busybox sh

Note: Make sure put the container name after the environment variable, not before that.

If you need to set up many variables, use the --env-file flag

For example,

 $ docker run --env-file ./my_env ubuntu bash

For any other help, look into the Docker help:

 $ docker run --help

Official documentation: https://docs.docker.com/compose/environment-variables/

0 values of basic types ⁽¹⁾⁽²⁾map to false.

Other values map to true.

This convention was established in original C, via its flow control statements; C didn't have a boolean type at the time.

It's a common error to assume that as function return values, false indicates failure. But in particular from main it's false that indicates success. I've seen this done wrong many times, including in the Windows starter code for the D language (when you have folks like Walter Bright and Andrei Alexandrescu getting it wrong, then it's just dang easy to get wrong), hence this heads-up beware beware.

There's no need to cast to bool for built-in types because that conversion is implicit. However, Visual C++ (Microsoft's C++ compiler) has a tendency to issue a performance warning (!) for this, a pure silly-warning. A cast doesn't suffice to shut it up, but a conversion via double negation, i.e. return !!x, works nicely. One can read !! as a “convert to bool” operator, much as --> can be read as “goes to”. For those who are deeply into readability of operator notation. ;-)

^{1) C++14 §4.12/1 “A zero value, null pointer value, or null member pointer value is converted to false; any other value is converted to true. For direct-initialization (8.5), a prvalue of type std::nullptr_t can be converted to a prvalue of type bool; the resulting value is false.”
2) C99 and C11 §6.3.1.2/1 “When any scalar value is converted to _Bool, the result is 0 if the value compares equal to 0; otherwise, the result is 1.”}

This works for me. Take your vector v

length(summary(as.factor(v),maxsum=50000))

Comment: set maxsum to be large enough to capture the number of unique values

or with the magrittr package

v %>% as.factor %>% summary(maxsum=50000) %>% length
