You should use variables to store the names.

Numbers can't store strings.

For me (using the Ubuntu Subsystem for Windows) the error message changed to:

 Permissions 0555 for 'key.pem' are too open

after using chmod 400. It turns out that using root as a default user was the reason.

Change this using the cmd:

 ubuntu config --default-user your_username

As others have pointed out, the cd command needs to start with a percentage sign:

%cd SwitchFrequencyAnalysis

Difference between % and !

Google Colab seems to inherit these syntaxes from Jupyter (which inherits them from IPython). Jake VanderPlas explains this IPython behaviour here. You can see the excerpt below.

If you play with IPython's shell commands for a while, you might notice that you cannot use !cd to navigate the filesystem:

In [11]: !pwd 
/home/jake/projects/myproject

In [12]: !cd ..

In [13]: !pwd 
/home/jake/projects/myproject 

The reason is that shell commands in the notebook are executed in a temporary subshell. If you'd like to change the working directory in a more enduring way, you can use the %cd magic command:

In [14]: %cd ..
/home/jake/projects

Another way to look at this: you need % because changing directory is relevant to the environment of the current notebook but not to the entire server runtime.

In general, use ! if the command is one that's okay to run in a separate shell. Use % if the command needs to be run on the specific notebook.

Try to do this:

SQL> select dept,count(*) "no of emp" from employee group by dept;

DEPT                  no of emp
-------------------- ----------
HR                            2
Account                       2
Admin                         3

I don't know about that specific SharePoint web service, but you can decorate a page method or a web service with <WebMethod()> (in VB.NET) to ensure that it serializes to JSON. You can probably just wrap the method that webservice.asmx uses internally, in your own web service.

Dave Ward has a nice walkthrough on this.

Here is an example

                            GHI             Temp  Power Day_Type
2016-03-15 06:00:00 -7.99999952505459e-7    18.3    0   NaN
2016-03-15 06:01:00 -7.99999952505459e-7    18.2    0   NaN
2016-03-15 06:02:00 -7.99999952505459e-7    18.3    0   NaN
2016-03-15 06:03:00 -7.99999952505459e-7    18.3    0   NaN
2016-03-15 06:04:00 -7.99999952505459e-7    18.3    0   NaN

but if this is all string values...as was in my case... Convert the desired columns to floats:

df_inv_29['GHI'] = df_inv_29.GHI.astype(float)
df_inv_29['Temp'] = df_inv_29.Temp.astype(float)
df_inv_29['Power'] = df_inv_29.Power.astype(float)

Your dataframe will now have float values :-)

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

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

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

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

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

To do this in any ES5-compatible environment

Object.keys(obj).length

(Browser support from here)
(Doc on Object.keys here, includes method you can add to non-ECMA5 browsers)

The number of column parameters in your insert query is 9, but you've only provided 8 values.

INSERT INTO dbname (id, Name, Description, shortDescription, Ingredients, Method, Length, dateAdded, Username) VALUES ('', '%s', '%s', '%s', '%s', '%s', '%s', '%s')

The query should omit the "id" parameter, because it is auto-generated (or should be anyway):

INSERT INTO dbname (Name, Description, shortDescription, Ingredients, Method, Length, dateAdded, Username) VALUES ('', '%s', '%s', '%s', '%s', '%s', '%s', '%s')

You need to use the makecert tool.

Open a command prompt as admin and type the following:

makecert -sky exchange -r -n "CN=<CertificateName>" -pe -a sha1 -len 2048 -ss My "<CertificateName>.cer"

Where <CertifcateName> = the name of your cert to create.

Then you can open the Certificate Manager snap-in for the management console by typing certmgr.msc in the Start menu, click personal > certificates > and your cert should be available.

Here is an article.

I think this question needs an updated answer, because both PostgreSQL and SQLDeveloper have been updated several times since it was originally asked.

I've got a PostgreSQL instance running in Azure, with SSLMODE=Require. While I've been using DBeaverCE to access that instance and generate an ER Diagram, I've gotten really familiar with SQLDeveloper, which is now at v19.4.

The instructions about downloading the latest PostgreSQL JDBC driver and where to place it are correct. What has changed, though, is where to configure your DB access.

You'll find a file $HOME/.sqldeveloper/system19.4.0.354.1759/o.jdeveloper.db.connection.19.3.0.354.1759/connections.json:

{
  "connections": [
    {
      "name": "connection-name-goes-here",
      "type": "jdbc",
      "info": {
        "customUrl": "jdbc:postgresql://your-postgresql-host:5432/DBNAME?sslmode=require",
        "hostname": "your-postgresql-host",
        "driver": "org.postgresql.Driver",
        "subtype": "SDPostgreSQL",
        "port": "5432",
        "SavePassword": "false",
        "RaptorConnectionType": "SDPostgreSQL",
        "user": "your_admin_user",
        "sslmode": "require"
      }
    }
  ]
}

You can use this connection with both Data Modeller and the admin functionality of SQLDeveloper. Specifying all the port, dbname and sslmode in the customUrl are required because SQLDeveloper isn't including the sslmode in what it sends via JDBC, so you have to construct it by hand.

I suspect that the xcopy command is the magic bullet you're looking for.

It can copy files, directories, and even entire drives while preserving the original directory hierarchy. There are also a handful of additional options available, compared to the basic copy command.

Check out the documentation here.

If your batch file only needs to run on Windows Vista or later, you can use robocopy instead, which is an even more powerful tool than xcopy, and is now built into the operating system. It's documentation is available here.

EXPLAIN PLAN FOR

In SQL Developer, you don't have to use EXPLAIN PLAN FOR statement. Press F10 or click the Explain Plan icon.

It will be then displayed in the Explain Plan window.

If you are using SQL*Plus then use DBMS_XPLAN.

For example,

SQL> EXPLAIN PLAN FOR
  2  SELECT * FROM DUAL;

Explained.

SQL> SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);

PLAN_TABLE_OUTPUT

"not equal" So in this case, $RESULT is tested to not be equal to zero.

However, the test is done numerically, not alphabetically:

n1 -ne n2     True if the integers n1 and n2 are not algebraically equal.

compared to:

s1 != s2      True if the strings s1 and s2 are not identical.

Correct Way would be :

<select id="select-type-basic" [(ngModel)]="status">
    <option *ngFor="let status_item of status_values">
    {{status_item}}
    </option>
</select>

Value Should be avoided inside option if the value is to be dynamic,since that will set the default value of the 'Select field'. Default Selection should be binded with [(ngModel)] and Options should be declared likewise.

status : any = "47";
status_values: any = ["45", "46", "47"];

Swift 3 version of Confile's answer:

import UIKit

extension UIView {
    func addTopBorderWithColor(color: UIColor, width: CGFloat) {
        let border = CALayer()
        border.backgroundColor = color.cgColor
        border.frame = CGRect(x: 0, y: 0, width: self.frame.size.width, height: width)
        self.layer.addSublayer(border)
    }

    func addRightBorderWithColor(color: UIColor, width: CGFloat) {
        let border = CALayer()
        border.backgroundColor = color.cgColor
        border.frame = CGRect(x: self.frame.size.width - width, y: 0, width: width, height: self.frame.size.height)
        self.layer.addSublayer(border)
    }

    func addBottomBorderWithColor(color: UIColor, width: CGFloat) {
        let border = CALayer()
        border.backgroundColor = color.cgColor
        border.frame = CGRect(x: 0, y: self.frame.size.height - width, width: self.frame.size.width, height: width)
        self.layer.addSublayer(border)
    }

    func addLeftBorderWithColor(color: UIColor, width: CGFloat) {
        let border = CALayer()
        border.backgroundColor = color.cgColor
        border.frame = CGRect(x: 0, y: 0, width: width, height: self.frame.size.height)
        self.layer.addSublayer(border)
    }
}

Usage when using auto layout:

class CustomView: UIView {

    override func awakeFromNib() {
        super.awakeFromNib()
    }

    override func layoutSubviews() {
        addBottomBorderWithColor(color: UIColor.white, width: 1)
    }
}

Swift 5.2, UIView+Extension

extension UIView {
    public func addViewBorder(borderColor:CGColor,borderWith:CGFloat,borderCornerRadius:CGFloat){
        self.layer.borderWidth = borderWith
        self.layer.borderColor = borderColor
        self.layer.cornerRadius = borderCornerRadius

    }
}

You used this extension;

yourView.addViewBorder(borderColor: #colorLiteral(red: 0.6, green: 0.6, blue: 0.6, alpha: 1), borderWith: 1.0, borderCornerRadius: 20)

If I understand your question correctly, you can always just wrap the get function like so:

var $someJqueryEl = $($('.myJqueryEls').get(3));

My problem: I don't want any style in my HTML content. I want my body directly scrollable without any scrollbar, and only a vertical scroll, working with CSS grids for any screen size.

The box-sizing value impact padding or margin solutions, they works with box-sizing:content-box.

I still need the "-moz-scrollbars-none" directive, and like gdoron and Mr_Green, I had to hide the scrollbar. I tried -moz-transform and -moz-padding-start, to impact only Firefox, but there was responsive side effects that needed too much work.

This solution works for HTML body content with "display: grid" style, and it is responsive.

/* Hide HTML and body scroll bar in CSS grid context */
html, body {
  position: static; /* Or relative or fixed ... */
  box-sizing: content-box; /* Important for hidding scrollbar */
  display: grid; /* For CSS grid */

  /* Full screen */
  width: 100vw;
  min-width: 100vw;
  max-width: 100vw;
  height: 100vh;
  min-height: 100vh;
  max-height: 100vh;
  margin: 0;
  padding: 0;
}

html {
  -ms-overflow-style: none;  /* Internet Explorer 10+ */
  overflow: -moz-scrollbars-none; /* Should hide the scroll bar */
}

/* No scroll bar for Safari and Chrome */
html::-webkit-scrollbar,
body::-webkit-scrollbar {
  display: none; /* Might be enough */
  background: transparent;
  visibility: hidden;
  width: 0px;
}

/* Firefox only workaround */
@-moz-document url-prefix() {
  /* Make HTML with overflow hidden */
  html {
    overflow: hidden;
  }

  /* Make body max height auto */
  /* Set right scroll bar out the screen  */
  body {
    /* Enable scrolling content */
    max-height: auto;

    /* 100vw +15px: trick to set the scroll bar out the screen */
    width: calc(100vw + 15px);
    min-width: calc(100vw + 15px);
    max-width: calc(100vw + 15px);

    /* Set back the content inside the screen */
    padding-right: 15px;
  }
}

body {
  /* Allow vertical scroll */
  overflow-y: scroll;
}

remove the http or https from wget https:github.com/facebook/facebook-php-sdk/archive/master.zip . this worked fine for me.

I also looked for a simple console replacement, just to dump text. So what I did was this function:

function remoteLog (arg) {
    var file = '/files/remoteLog.php';
    $.post(file, {text: arg});
}

The remote PHP file recorded all the output to a database in arg. It took me 5 minutes (OK, on the server side I used a simple logging library that records and displays text messages, but still...).

The money datatype on SQL Server has four digits after the decimal.

From SQL Server 2000 Books Online:

Monetary data represents positive or negative amounts of money. In Microsoft® SQL Server™ 2000, monetary data is stored using the money and smallmoney data types. Monetary data can be stored to an accuracy of four decimal places. Use the money data type to store values in the range from -922,337,203,685,477.5808 through +922,337,203,685,477.5807 (requires 8 bytes to store a value). Use the smallmoney data type to store values in the range from -214,748.3648 through 214,748.3647 (requires 4 bytes to store a value). If a greater number of decimal places are required, use the decimal data type instead.

• The children of a row-flexbox container automatically fill the container's vertical space.

Use on :

$('#registered_participants').on('click', '.new_participant_form', function() {

So that the click is delegated to any element in #registered_participants having the class new_participant_form, even if it's added after you bound the event handler.

In my strange case, Intellij remembers forever about my project even if I delete .iml... Thus I did the following:

1. Close project. Delete the .iml file.
2. Rename my project directory (say my_proj) to my_proj_backup.
3. (Possibly not needed) Open my_proj_backup in Intellij and close.
4. Create an empty directory called my_proj, and open it in Intellij. Then close it.
5. Remove the my_proj and move my_proj_backup back to my_proj. Then open my_proj in Intellij.

Then it happily forgot the old my_proj :)

if you are windows user, then it's in C:\Users\your_user_name\Envs. You can delete it from there.

Also try in command prompt rmvirtualenv environment name.

I tried with command prompt so it said deleted but it was still existed. So i manually delete it.

• Processing: Java derived language

• Wiring: C/C++ derived language (Wiring is derived from Processing)

• Early versions of Arduino: C/C++ derived (Arduino IDE is derived from Wiring)

For Arduino for example the IDE preprocessor is adding some #defines and some C/C++ files before giving all to gcc.

I just install stylus by default under my home dir, so I just use npm uninstall stylus to detach it, or you can try npm rm <package_name> out.

A slightly different implementation of a half sieve using Numpy:

http://rebrained.com/?p=458

import math
import numpy
def prime6(upto):
    primes=numpy.arange(3,upto+1,2)
    isprime=numpy.ones((upto-1)/2,dtype=bool)
    for factor in primes[:int(math.sqrt(upto))]:
        if isprime[(factor-2)/2]: isprime[(factor*3-2)/2:(upto-1)/2:factor]=0
    return numpy.insert(primes[isprime],0,2)

Can someone compare this with the other timings? On my machine it seems pretty comparable to the other Numpy half-sieve.

From LDAP, there is not a query method to determine an empty string.

The best practice would be to scrub your data inputs to LDAP as an empty or null value in LDAP is no value at all.

To determine this you would need to query for all with a value (manager=*) and then use code to determine the ones that were a "space" or null value.

And as Terry said, storing an empty or null value in an attribute of DN syntax is wrong.

Some LDAP server implementations will not permit entering a DN where the DN entry does not exist.

Perhaps, you could, if your DN's are consistent, use something like:

(&(!(manager=cn*))(manager=*))

This should return any value of manager where there was a value for manager and it did not start with "cn".

However, some LDAP implementations will not allow sub-string searches on DN syntax attributes.

The traceback module and sys.exc_info are overkill for tracking down the source of an exception. That's all in the default traceback. So instead of calling exit(1) just re-raise:

try:
    assert "birthday cake" == "ice cream cake", "Should've asked for pie"
except AssertionError:
    print 'Houston, we have a problem.'
    raise

Which gives the following output that includes the offending statement and line number:

Houston, we have a problem.
Traceback (most recent call last):
  File "/tmp/poop.py", line 2, in <module>
    assert "birthday cake" == "ice cream cake", "Should've asked for pie"
AssertionError: Should've asked for pie

Similarly the logging module makes it easy to log a traceback for any exception (including those which are caught and never re-raised):

import logging

try:
    assert False == True 
except AssertionError:
    logging.error("Nothing is real but I can't quit...", exc_info=True)

.phtml was the standard file extension for PHP 2 programs. .php3 took over for PHP 3. When PHP 4 came out they switched to a straight .php.

The older file extensions are still sometimes used, but aren't so common.

What do you mean by delete? In Python, removing a reference (or a name) can be done with the del keyword, but if there are other names to the same object that object will not be deleted.

--> test = 3
--> print(test)
3
--> del test
--> print(test)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'test' is not defined

compared to:

--> test = 5
--> other is test  # check that both name refer to the exact same object
True
--> del test       # gets rid of test, but the object is still referenced by other
--> print(other)
5

With git there is a https format

https://github.com/equivalent/we_demand_serverless_ruby.git

This format accepts User + password

https://bot-user:[email protected]/equivalent/we_demand_serverless_ruby.git

So what you can do is create a new user that will be used just as a bot, add only enough permissions that he can just read the repository you want to load in NPM modules and just have that directly in your packages.json

 Github > Click on Profile > Settings > Developer settings > Personal access tokens > Generate new token

In Select Scopes part, check the on repo: Full control of private repositories

This is so that token can access private repos that user can see

Now create new group in your organization, add this user to the group and add only repositories that you expect to be pulled this way (READ ONLY permission !)

You need to be sure to push this config only to private repo

Then you can add this to your / packages.json (bot-user is name of user, xxxxxxxxx is the generated personal token)

// packages.json


{
  // ....
    "name_of_my_lib": "https://bot-user:[email protected]/ghuser/name_of_my_lib.git"
  // ...
}

echo -n "$PROC_NAME $(printf '\055%.0s' {1..40})" | head -c 40 ; echo -n " [UP]"

Explanation:

• printf '\055%.0s' {1..40} - Create 40 dashes
  (dash is interpreted as option so use escaped ascii code instead)
• "$PROC_NAME ..." - Concatenate $PROC_NAME and dashes
• | head -c 40 - Trim string to first 40 chars

There is also a slight difference in the html output for a string data type.

Html.EditorFor:  
<input id="Contact_FirstName" class="text-box single-line" type="text" value="Greg" name="Contact.FirstName">

Html.TextBoxFor:
<input id="Contact_FirstName" type="text" value="Greg" name="Contact.FirstName">

For security reasons, you can only get the url for as long as the contents of the iframe, and the referencing javascript, are served from the same domain. As long as that is true, something like this will work:

document.getElementById("iframe_id").contentWindow.location.href

If the two domains are mismatched, you'll run into cross site reference scripting security restrictions.

I would use the Apache Commons Lang library. It has a class called StringUtils that is useful for all sorts of String operations. For checking if a String is not all whitespaces, you can use the following:

StringUtils.isBlank(<your string>)

It sounds like you're looking for applicationHost.config, which is located in C:\Windows\System32\inetsrv\config.

Yes, it's an XML file, and yes, editing the file by hand will affect the IIS config after a restart. You can think of IIS Manager as a GUI front-end for editing applicationHost.config and web.config.

substitute:

mMyListView.invalidate();

for:

((BaseAdapter) mMyListView.getAdapter()).notifyDataSetChanged();

Error 4 means "The cause was a user-mode read resulting in no page being found.". There's a tool that decodes it here.

Here's the definition from the kernel. Keep in mind that 4 means that bit 2 is set and no other bits are set. If you convert it to binary that becomes clear.

/*

Now then, "ip 00007f9bebcca90d" means the instruction pointer was at 0x00007f9bebcca90d when the segfault happened.

"libQtWebKit.so.4.5.2[7f9beb83a000+f6f000]" tells you:

• The object the crash was in: "libQtWebKit.so.4.5.2"
• The base address of that object "7f9beb83a000"
• How big that object is: "f6f000"

If you take the base address and subtract it from the ip, you get the offset into that object:

0x00007f9bebcca90d - 0x7f9beb83a000 = 0x49090D

Then you can run addr2line on it:

addr2line -e /usr/lib64/qt45/lib/libQtWebKit.so.4.5.2 -fCi 0x49090D

In my case it wasn't successful, either the copy I installed isn't identical to yours, or it's stripped.

This happened to me when I was debugging my C# WinForms application in Visual Studio. My application makes calls to Win32 stuff via DllImport, e.g.

[DllImport("Secur32.dll", SetLastError = false)]
private static extern uint LsaEnumerateLogonSessions(out UInt64 LogonSessionCount, out IntPtr LogonSessionList);

Running Visual Studio "as Administrator" solved the problem for me.

There is also this tool you can use. It supports multi-events .ics file creation. It also supports timezone as well.

You can find the first and last visible children of the recycle view and check if the view you're looking for is in the range:

var visibleChild: View = rv.getChildAt(0)
val firstChild: Int = rv.getChildAdapterPosition(visibleChild)
visibleChild = rv.getChildAt(rv.childCount - 1)
val lastChild: Int = rv.getChildAdapterPosition(visibleChild)
println("first visible child is: $firstChild")
println("last visible child is: $lastChild")

In the current version (Android Studio 0.5.2) there is now a device type for "Google APIs x86 (Google Inc.) - API Level 19".

An absolute URL includes the parts before the "path" part - in other words, it includes the scheme (the http in http://foo/bar/baz) and the hostname (the foo in http://foo/bar/baz) (and optionally port, userinfo and port).

Relative URLs start with a path.

Absolute URLs are, well, absolute: the location of the resource can be resolved looking only at the URL itself. A relative URL is in a sense incomplete: to resolve it, you need the scheme and hostname, and these are typically taken from the current context. For example, in a web page at

http://myhost/mypath/myresource1.html

you could put a link like so

<a href="pages/page1">click me</a>

In the href attribute of the link, a relative URLs used, and if it is clicked, it has to be resolved in order to follow it. In this case, the current context is

http://myhost/mypath/myresource1.html

so the schema, hostname, and leading path of these are taken and prepended to pages/page1, yielding

http://myhost/mypath/pages/page1

If the link would have been:

<a href="/pages/page1">click me</a>

(note the / appearing at the start of the URL) then it would have been resolved as

http://myhost/pages/page1

because the leading / indicates the root of the host.

In a webapplication, I would advise to use relative URLs for all resources that belong to your app. That way, if you change the location of the pages, everything will continue to work. Any external resources (could be pages completely outside your application, but also static content that you deliver through a content delivery network) should always be pointed to using absolute URLs: if you don't there simply is no way to locate them, because they reside on a different server.

First off, RangeToHTML. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b?u?t?c?h?e?r?e?d? modified.

On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.

For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

No, MSSQL doesn't allow such queries. You should use col LIKE '...' OR col LIKE '...' etc.

If possible I would suggest creating the Path directly from the path elements:

Path path = Paths.get("C:", "dir1", "dir2", "dir3");
// if needed
String textPath = path.toString(); // "C:\\dir1\\dir2\\dir3"

Ensure your encoding is correct for all of your files, this can sometimes happen if you have the encoding wrong for your file or the wrong encoding in your XML header.

So, if I have the following NewFile.xml:

<?xml version="1.0" encoding="UTF-16"?>
<bar foo="foiré" />

And the eclipse encoding is UTF-8:

The encoding of your file, the defined encoding in Eclipse (through Properties->Resource) and the declared encoding in the XML document all need to agree.

The validator is attempting to read the file, expecting <?xml ... but because the encoding is different from that expected, it's not finding it. Hence the error: Content is not allowed in prolog. The prolog is the bit before the <?xml declaration.

EDIT: Sorry, didn't realise that the .xml files were generated and actually contain javascript.

When you suspend the validators, the error messages that you've generated don't go away. To get them to go away, you have to manually delete them.

1. Suspend the validators
2. Click on the 'Content is not allowed in prolog' message, right click and delete. You can select multiple ones, or all of them.
3. Do a Project->Clean. The messages should not come back.

I think that because you've suspended the validators, Eclipse doesn't realise it has to delete the old error messages which came from the validators.

Apparently, the compiler thinks NSSearchPathDirectory:0 is an array, and of course it expects the type NSSearchPathDirectory instead. Certainly not a helpful error message.

But as to the reasons:

First, you are confusing the argument names and types. Take a look at the function definition:

func NSSearchPathForDirectoriesInDomains(
    directory: NSSearchPathDirectory,
    domainMask: NSSearchPathDomainMask,
    expandTilde: Bool) -> AnyObject[]!

• directory and domainMask are the names, you are using the types, but you should leave them out for functions anyway. They are used primarily in methods.
• Also, Swift is strongly typed, so you shouldn't just use 0. Use the enum's value instead.
• And finally, it returns an array, not just a single path.

So that leaves us with (updated for Swift 2.0):

let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]

and for Swift 3:

let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]

It's \n. When you're reading or writing text mode files, or to stdin/stdout etc, you must use \n, and C will handle the translation for you. When you're dealing with binary files, by definition you are on your own.

Here is a very simple jade file that have a loop in it. Jade is very sensitive about white space. After loop definition line (for) you should give an indent(tab) to stuff that want to go inside the loop. You can do this without {}:

- var arr=['one', 'two', 'three'];
- var s = 'string';
doctype html
html
    head
    body
        section= s
        - for (var i=0; i<3; i++)
            div= arr[i]

A php.ini file is not installed by default with Wordpress. You may have one already installed by your web host. Look in your root directory or ask your web host or read your web host's documentation on how to install one.

Look for max_execution_time in your php.ini file and change to 60 or 90

It may be better to set the surefire-plugin version in the parent pom, otherwise including it as a dependency will override any configuration (includes file patterns etc) that may be inherited, e.g. from Spring Boots spring-boot-starter-test pom using pluginManagement

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.0</version>
            </plugin>

I have several JDK (1.4, 1.5, 1.6) installed in C:\Java with their JREs. Then I let Sun update the public JRE in C:\Program Files\Java.
Lately there is an improvement, installing in jre6. Previously, there was a different folder per new version (1.5.0_4, 1.5.0_5, etc.), which was taking lot of space

For using scroll view along with Relative layout :

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:fillViewport="true"> <!--IMPORTANT otherwise backgrnd img. will not fill the whole screen -->

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        android:background="@drawable/background_image"
    >

    <!-- Bla Bla Bla i.e. Your Textviews/Buttons etc. -->
    </RelativeLayout>
</ScrollView>

This will also work

$(this).parent().parent().find('td').text()

  xsel -b

Does the job for X Window, and it is mostly already installed. A look in the man page of xsel is worth the effort.

Generally speaking, for boolean or bit data types, you would use 0 or 1 like so:

UPDATE tbl SET bitCol = 1 WHERE bitCol = 0

You want reorder(). Here is an example with dummy data

set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))

require("ggplot2")

p1 <- ggplot(df, aes(x = Category, y = Count)) +
         geom_bar(stat = "identity")

p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
         geom_bar(stat = "identity")

require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))

Giving:

Use reorder(Category, Count) to have Category ordered from low-high.

The difference between creating an array with the implicit array and the array constructor is subtle but important.

When you create an array using

var a = [];

You're telling the interpreter to create a new runtime array. No extra processing necessary at all. Done.

If you use:

var a = new Array();

You're telling the interpreter, I want to call the constructor "Array" and generate an object. It then looks up through your execution context to find the constructor to call, and calls it, creating your array.

You may think "Well, this doesn't matter at all. They're the same!". Unfortunately you can't guarantee that.

Take the following example:

function Array() {
    this.is = 'SPARTA';
}

var a = new Array();
var b = [];

alert(a.is);  // => 'SPARTA'
alert(b.is);  // => undefined
a.push('Woa'); // => TypeError: a.push is not a function
b.push('Woa'); // => 1 (OK)

In the above example, the first call will alert 'SPARTA' as you'd expect. The second will not. You will end up seeing undefined. You'll also note that b contains all of the native Array object functions such as push, where the other does not.

While you may expect this to happen, it just illustrates the fact that [] is not the same as new Array().

It's probably best to just use [] if you know you just want an array. I also do not suggest going around and redefining Array...

Interestingly enough I tried both of these in LinqPad and the variant using group from Dmitry Gribkov by appears to be quicker. (also the final distinct is not required as the result is already distinct.

My (somewhat simple) code was:

public class Pair 
{ 
    public int id {get;set;}
    public string Arb {get;set;}
}

void Main()
{

    var theList = new List<Pair>();
    var randomiser = new Random();
    for (int count = 1; count < 10000; count++)
    {
        theList.Add(new Pair 
        {
            id = randomiser.Next(1, 50),
            Arb = "not used"
        });
    }

    var timer = new Stopwatch();
    timer.Start();
    var distinct = theList.GroupBy(c => c.id).Select(p => p.First().id);
    timer.Stop();
    Debug.WriteLine(timer.Elapsed);

    timer.Start();
    var otherDistinct = theList.Select(p => p.id).Distinct();
    timer.Stop();
    Debug.WriteLine(timer.Elapsed);
}

Well, I had the same trouble ... so I found this thread

I think the answer from user:"pmg" does not work always.

unsigned int int_to_int(unsigned int k) {
    return (k == 0 || k == 1 ? k : ((k % 2) + 10 * int_to_int(k / 2)));
}

Reason: the binary representation is stored as an integer. That is quite limited. Imagine converting a decimal to binary:

 dec 255  -> hex 0xFF  -> bin 0b1111_1111
 dec 1023 -> hex 0x3FF -> bin 0b11_1111_1111

and you have to store this binary representation as it were a decimal number.

I think the solution from Andy Finkenstadt is the closest to what you need

unsigned int_to_int(unsigned int k) {
    char buffer[65]; // any number higher than sizeof(unsigned int)*bits_per_byte(8)
    return itoa( atoi(k, buffer, 2) );
}

but still this does not work for large numbers. No suprise, since you probably don't really need to convert the string back to decimal. It makes less sense. If you need a binary number usually you need for a text somewhere, so leave it in string format.

simply use itoa()

char buffer[65];
itoa(k, buffer, 2);

Run this

$ rbenv init
# Load rbenv automatically by appending
# the following to ~/.zshrc:

eval "$(rbenv init -)"

Follow instructions, (in my case add to ~/.zshrc) ;)

Also important: Changes only take effect if you reboot your console. Two options

• Enter source <modified file>
• close and open again

Also make sure avoid not use [ValidateAntiForgeryToken] under [HttpGet].

An enum is only guaranteed to be large enough to hold int values. The compiler is free to choose the actual type used based on the enumeration constants defined so it can choose a smaller type if it can represent the values you define. If you need enumeration constants that don't fit into an int you will need to use compiler-specific extensions to do so.

Important:

I'm sorry to say that the response from "Borealid" is imprecise and somewhat incorrect - firstly there is no relation to statefulness or statelessness to answer this question, and most importantly the definition of the tuple for a socket is incorrect.

First remember below two rules:

1. Primary key of a socket: A socket is identified by {SRC-IP, SRC-PORT, DEST-IP, DEST-PORT, PROTOCOL} not by {SRC-IP, SRC-PORT, DEST-IP, DEST-PORT} - Protocol is an important part of a socket's definition.

2. OS Process & Socket mapping: A process can be associated with (can open/can listen to) multiple sockets which might be obvious to many readers.

Example 1: Two clients connecting to same server port means: socket1 {SRC-A, 100, DEST-X,80, TCP} and socket2{SRC-B, 100, DEST-X,80, TCP}. This means host A connects to server X's port 80 and another host B also connects to same server X to the same port 80. Now, how the server handles these two sockets depends on if the server is single threaded or multiple threaded (I'll explain this later). What is important is that one server can listen to multiple sockets simultaneously.

To answer the original question of the post:

Irrespective of stateful or stateless protocols, two clients can connect to same server port because for each client we can assign a different socket (as client IP will definitely differ). Same client can also have two sockets connecting to same server port - since such sockets differ by SRC-PORT. With all fairness, "Borealid" essentially mentioned the same correct answer but the reference to state-less/full was kind of unnecessary/confusing.

To answer the second part of the question on how a server knows which socket to answer. First understand that for a single server process that is listening to same port, there could be more than one sockets (may be from same client or from different clients). Now as long as a server knows which request is associated with which socket, it can always respond to appropriate client using the same socket. Thus a server never needs to open another port in its own node than the original one on which client initially tried to connect. If any server allocates different server-ports after a socket is bound, then in my opinion the server is wasting its resource and it must be needing the client to connect again to the new port assigned.

A bit more for completeness:

Example 2: It's a very interesting question: "can two different processes on a server listen to the same port". If you do not consider protocol as one of parameter defining socket then the answer is no. This is so because we can say that in such case, a single client trying to connect to a server-port will not have any mechanism to mention which of the two listening processes the client intends to connect to. This is the same theme asserted by rule (2). However this is WRONG answer because 'protocol' is also a part of the socket definition. Thus two processes in same node can listen to same port only if they are using different protocol. For example two unrelated clients (say one is using TCP and another is using UDP) can connect and communicate to the same server node and to the same port but they must be served by two different server-processes.

Server Types - single & multiple:

When a server's processes listening to a port that means multiple sockets can simultaneously connect and communicate with the same server-process. If a server uses only a single child-process to serve all the sockets then the server is called single-process/threaded and if the server uses many sub-processes to serve each socket by one sub-process then the server is called multi-process/threaded server. Note that irrespective of the server's type a server can/should always uses the same initial socket to respond back (no need to allocate another server-port).

Suggested Books and rest of the two volumes if you can.

A Note on Parent/Child Process (in response to query/comment of 'Ioan Alexandru Cucu')

Wherever I mentioned any concept in relation to two processes say A and B, consider that they are not related by parent child relationship. OS's (especially UNIX) by design allow a child process to inherit all File-descriptors (FD) from parents. Thus all the sockets (in UNIX like OS are also part of FD) that a process A listening to, can be listened by many more processes A1, A2, .. as long as they are related by parent-child relation to A. But an independent process B (i.e. having no parent-child relation to A) cannot listen to same socket. In addition, also note that this rule of disallowing two independent processes to listen to same socket lies on an OS (or its network libraries) and by far it's obeyed by most OS's. However, one can create own OS which can very well violate this restrictions.

1. Create a .gitignore file, so to do that, you just create any blank .txt file.

2. Then you have to change its name writing the following line on the cmd (where git.txt is the name of the file you've just created):

   rename git.txt .gitignore

3. Then you can open the file and write all the untracked files you want to ignore for good. For example, mine looks like this:

```

OS junk files
[Tt]humbs.db
*.DS_Store

#Visual Studio files
*.[Oo]bj

There's a whole collection of useful .gitignore files by GitHub

4. Once you have this, you need to add it to your git repository just like any other file, only it has to be in the root of the repository.

5. Then in your terminal you have to write the following line:

   git config --global core.excludesfile ~/.gitignore_global

You can also create a global .gitignore file, which is a list of rules for ignoring files in every Git repository on your computer. For example, you might create the file at ~/.gitignore_global and add some rules to it.

Open Terminal. Run the following command in your terminal: git config --global core.excludesfile ~/.gitignore_global

If the respository already exists then you have to run these commands:

git rm -r --cached .
git add .
git commit -m ".gitignore is now working"

If the step 2 doesn´t work then you should write the hole route of the files that you would like to add.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<script>_x000D_
$(document).ready(function(){_x000D_
    var form=$("#myForm");_x000D_
    $("#smt").click(function(){_x000D_
        $.ajax({_x000D_
            type:"POST",_x000D_
            url:form.attr("action"),_x000D_
            data:form.serialize(),_x000D_
            success: function(response){_x000D_
                console.log(response);  _x000D_
            }_x000D_
        });_x000D_
    });_x000D_

</script>

This is perfect code , there is no problem.. You have to check that in php script.

We need to add host security certificate to php.ini file. For local developement enviroment we can add cacert.pem in your local php.ini.

do phpinfo(); and file your php.ini path open and add uncomment ;curl.capath

curl.capath=path_of_your_cacert.pem

You can use the sDom option for this.

Default with search input in its own div:

sDom: '<"search-box"r>lftip'

If you use jQuery UI (bjQueryUI set to true):

sDom: '<"search-box"r><"H"lf>t<"F"ip>'

The above will put the search/filtering input element into it's own div with a class named search-box that is outside of the actual table.

Even though it uses its special shorthand syntax it can actually take any HTML you throw at it.

Anything that is not stored on an EBS volume that is mounted to the instance will be lost.

For example, if you mount your EBS volume at /mystuff, then anything not in /mystuff will be lost. If you don't mount an ebs volume and save stuff on it, then I believe everything will be lost.

You can create an AMI from your current machine state, which will contain everything in your ephemeral storage. Then, when you launch a new instance based on that AMI it will contain everything as it is now.

Update: to clarify based on comments by mattgmg1990 and glenn bech:

Note that there is a difference between "stop" and "terminate". If you "stop" an instance that is backed by EBS then the information on the root volume will still be in the same state when you "start" the machine again. According to the documentation, "By default, the root device volume and the other Amazon EBS volumes attached when you launch an Amazon EBS-backed instance are automatically deleted when the instance terminates" but you can modify that via configuration.

Select s.stock_code,s.stock_desc,s.stock_desc_ar,
mc.category_name,s.sel_price,
case when s.allow_discount=0 then 'Non Promotional Item' else 'Prmotional 
item' end 'Promotion'
From tbl_stock s inner join tbl_stock_category c on s.stock_id=c.stock_id
inner join tbl_category mc on c.category_id=mc.category_id
where mc.category_id=2 and s.isSerialBased=0 

In the servlet code, with the instruction request.setAttribute("servletName", categoryList), you save your list in the request object, and use the name "servletName" for refering it.
By the way, using then name "servletName" for a list is quite confusing, maybe it's better call it "list" or something similar: request.setAttribute("list", categoryList)
Anyway, suppose you don't change your serlvet code, and store the list using the name "servletName". When you arrive to your JSP, it's necessary to retrieve the list from the request, and for that you just need the request.getAttribute(...) method.

<%  
// retrieve your list from the request, with casting 
ArrayList<Category> list = (ArrayList<Category>) request.getAttribute("servletName");

// print the information about every category of the list
for(Category category : list) {
    out.println(category.getId());
    out.println(category.getName());
    out.println(category.getMainCategoryId());
}
%>

Use this class.

public static class Extensions
{
    public static void CopyTo(this DirectoryInfo source, DirectoryInfo target, bool overwiteFiles = true)
    {
        if (!source.Exists) return;
        if (!target.Exists) target.Create();

        Parallel.ForEach(source.GetDirectories(), (sourceChildDirectory) => 
            CopyTo(sourceChildDirectory, new DirectoryInfo(Path.Combine(target.FullName, sourceChildDirectory.Name))));

        foreach (var sourceFile in source.GetFiles())
            sourceFile.CopyTo(Path.Combine(target.FullName, sourceFile.Name), overwiteFiles);
    }
    public static void CopyTo(this DirectoryInfo source, string target, bool overwiteFiles = true)
    {
        CopyTo(source, new DirectoryInfo(target), overwiteFiles);
    }
}

IN ES5

E.G. you have this kind of object:

var ELEMENTS = {
    STEP_ELEMENT: { ID: "0", imageName: "el_0.png" },
    GREEN_ELEMENT: { ID: "1", imageName: "el_1.png" },
    BLUE_ELEMENT: { ID: "2", imageName: "el_2.png" },
    ORANGE_ELEMENT: { ID: "3", imageName: "el_3.png" },
    PURPLE_ELEMENT: { ID: "4", imageName: "el_4.png" },
    YELLOW_ELEMENT: { ID: "5", imageName: "el_5.png" }
};

And now if you want to have a function that if you pass '0' as a param - to get 'STEP_ELEMENT', if '2' to get 'BLUE_ELEMENT' and so for

function(elementId) {
    var element = null;

    Object.keys(ELEMENTS).forEach(function(key) {
        if(ELEMENTS[key].ID === elementId.toString()){
            element = key;
            return;
        }    
    });

    return element;
}

This is probably not the best solution to the problem but its good to give you an idea how to do it.

Cheers.

If you pass jQuery a function, it will not run until the page has loaded:

<script type="text/javascript">
$(function() {
    //your header rotation code goes here
});
</script>

I had the same issue on my Mac machine (correctly followed all the installation steps suggested by brew install).

Deleting the error file fixed it for me:

sudo rm -rf /usr/local/var/mysql/dev.work.err (dev.work is my hostname)

This worked because dev.work.err was owned by _mysql:wheel instead of my own username. CHOWN-ing the error file would have probably fixed it as well.

I have done this by assigning footer an id and then styling using css :

    <table border="1" class="dataTable" id="dataTable_${dtoItem.key}" >
     <thead>
        <tr>
            <th></th>

        </tr>
    </thead>
 <tfoot>
    <tr>
            <th id="FooterHidden"></th>
    </tr>
</tfoot>
<tbody>

    <tr>

                <td class="copyableField"></td>

    </tr>
 </tbody>
</table>

then styling using css :

#FooterHidden{
   display: none;
}

As above mentioned ways aren't working for me.

I use this class to handle database.I hope it will help some one in future.

Happy coding.

The following is working code with two ways of achieving this:

I use this

function getBrowserName() {
    var name = "Unknown";
    if(navigator.userAgent.indexOf("MSIE")!=-1){
        name = "MSIE";
    }
    else if(navigator.userAgent.indexOf("Firefox")!=-1){
        name = "Firefox";
    }
    else if(navigator.userAgent.indexOf("Opera")!=-1){
        name = "Opera";
    }
    else if(navigator.userAgent.indexOf("Chrome") != -1){
        name = "Chrome";
    }
    else if(navigator.userAgent.indexOf("Safari")!=-1){
        name = "Safari";
    }
    return name;   
}

if( getBrowserName() == "Safari" ){
    alert("You are using Safari");
}else{
    alert("You are surfing on " + getBrowserName(name));
}

I had the same problem because of an table column which was defined as ENUM('x','y','z') and later on I was trying to save the value 'a' into this column, thus I got the mentioned error.

Solved by altering the table column definition and added value 'a' into the enum set.

You may define your enum like so and use cast where needed

public enum MyEnum
{
    VariablePeriods = 1,
    FixedPeriods = 2
}

Usage

public class Entity
{
    public MyEnum Property { get; set; }
}

var returnedFromDB = 1;
var entity = new Entity();
entity.Property = (MyEnum)returnedFromDB;

There sure is (in gnuplot 4.4+):

plot for [i=1:1000] 'data'.i.'.txt' using 1:2 title 'Flow '.i

The variable i can be interpreted as a variable or a string, so you could do something like

plot for [i=1:1000] 'data'.i.'.txt' using 1:($2+i) title 'Flow '.i

if you want to have lines offset from each other.

Type help iteration at the gnuplot command line for more info.

Also be sure to see @DarioP's answer about the do for syntax; that gives you something closer to a traditional for loop.

And if you're using Xamarin (monotouch) framework, simply call

SystemSound.Vibrate.PlayAlertSound()

Make sure you first check for null and empty and ten converts existing string to upper. Use S.O.P if want to see outputs otherwise boolean like Rabiz did.

 public static void main(String[] args)
 {
     System.out.println("Enter name");
     Scanner kb = new Scanner (System.in);
     String text =  kb.next();

     if ( null == text || text.isEmpty())
     {
         System.out.println("Text empty");
     }
     else if (text.charAt(0) == (text.toUpperCase().charAt(0)))
     {
         System.out.println("First letter in word "+ text + " is upper case");
     }
  }

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"
          ^^^^^^^^^^
          |        |
          1       10

Make the div

runat="server" 

and do

if (lstFilePrefix1.SelectedValue=="Prefix2")
{
    int TotalRows = this.BindList(1);
    this.Prepare_Pager(TotalRows);
    data.Style["display"] = "block";
}

Your method isn't working because the javascript is being rendered in the top of the body tag, before the div is rendered. You'd have to include code to tell the javascript to wait for the DOM to be completely ready to take on your request, which would probably be easiest to do with jQuery.

First of all you should get JdK 8.

if you have Jdk installed.

you should set its path using cmd prompt or system variables.

sometimes it can happen that the path is not set due to which eclipse is unable to get the properties for jdk.

Installing latest ecipse luna can solve your problem.

i have indigo and luna. i can set 1.8 in luna but 1.7 in indigo.Eclipse luna

You can check the eclipse site. it says that the eclipse luna was certainly to associate the properties for jdk 8.

I got the same error with a class like the following StockPickBean. Called from this code:

List<StockPickBean> beansListcatMap.getValue();
beansList.sort(StockPickBean.Comparators.VALUE);

public class StockPickBean implements Comparable<StockPickBean> {
    private double value;
    public double getValue() { return value; }
    public void setValue(double value) { this.value = value; }

    @Override
    public int compareTo(StockPickBean view) {
        return Comparators.VALUE.compare(this,view); //return 
        Comparators.SYMBOL.compare(this,view);
    }

    public static class Comparators {
        public static Comparator<StockPickBean> VALUE = (val1, val2) -> 
(int) 
         (val1.value - val2.value);
    }
}

After getting the same error:

java.lang.IllegalArgumentException: Comparison method violates its general contract!

I changed this line:

public static Comparator<StockPickBean> VALUE = (val1, val2) -> (int) 
         (val1.value - val2.value);

to:

public static Comparator<StockPickBean> VALUE = (StockPickBean spb1, 
StockPickBean spb2) -> Double.compare(spb2.value,spb1.value);

That fixes the error.

The double '%' works also in ".Format(…). Example (with iDrawApertureMask == 87, fCornerRadMask == 0.05): csCurrentLine.Format("\%ADD%2d%C,%6.4f*\%",iDrawApertureMask,fCornerRadMask) ; gives the desired and expected value of (string contents in) csCurrentLine; "%ADD87C, 0.0500*%"

It's not magic.

The behavior of this code in C is described in section 6.7.8.21 of the C specification (online draft of C spec): for the elements that don't have a specified value, the compiler initializes pointers to NULL and arithmetic types to zero (and recursively applies this to aggregates).

The behavior of this code in C++ is described in section 8.5.1.7 of the C++ specification (online draft of C++ spec): the compiler aggregate-initializes the elements that don't have a specified value.

Also, note that in C++ (but not C), you can use an empty initializer list, causing the compiler to aggregate-initialize all of the elements of the array:

char array[100] = {};

As for what sort of code the compiler might generate when you do this, take a look at this question: Strange assembly from array 0-initialization

I am using JPA (OpenJPA implementation from Apache which is based on the KODO JDO codebase which is 5+ years old and extremely fast/reliable). IMHO anyone who tells you to bypass the specs is giving you bad advice. I put the time in and was definitely rewarded. With either JDO or JPA you can change vendors with minimal changes (JPA has orm mapping so we are talking less than a day to possibly change vendors). If you have 100+ tables like I do this is huge. Plus you get built0in caching with cluster-wise cache evictions and its all good. SQL/Jdbc is fine for high performance queries but transparent persistence is far superior for writing your algorithms and data input routines. I only have about 16 SQL queries in my whole system (50k+ lines of code).

try importing the below package from random import*

There is a solution here : Add

/full /netfx at the end of the path!

This should clear almost all. You should only be left with SQL Server.

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

lea is an abbreviation of "load effective address". It loads the address of the location reference by the source operand to the destination operand. For instance, you could use it to:

lea ebx, [ebx+eax*8]

to move ebx pointer eax items further (in a 64-bit/element array) with a single instruction. Basically, you benefit from complex addressing modes supported by x86 architecture to manipulate pointers efficiently.

The variables you need are explained here in the jenkins wiki: https://wiki.jenkins.io/display/JENKINS/Features+controlled+by+system+properties

The default variable ITEM_ROOTDIR points to a directory inside the jenkins installation. As you already found out you need:

• Workspace Root Directory: E:/myJenkinsRootFolderOnE/${ITEM_FULL_NAME}/workspace
• Build Record Root Directory: E:/myJenkinsRootFolderOnE/${ITEM_FULL_NAME}/builds

You need to achieve this through config.xml nowerdays. Citing from the wiki page linked above:

This used to be a UI setting, but was removed in 2.119 as it did not support migration of existing build records and could lead to build-related errors until restart.

One technique I think is a little easier and that hasn't been mentioned before here:

var asdf = new [] { 
    (Age: 1, Name: "cow"), 
    (Age: 2, Name: "bird")
}.ToList();

I think that's a little cleaner than:

var asdf = new List<Tuple<int, string>> { 
    (Age: 1, Name: "cow"), 
    (Age: 2, Name: "bird")
};

$ git remote remove <name>

ie.

$ git remote remove upstream

that should do the trick

You can use an event listener to close the clip after it is played

import java.io.File;
import javax.sound.sampled.*;

public void play(File file) 
{
    try
    {
        final Clip clip = (Clip)AudioSystem.getLine(new Line.Info(Clip.class));

        clip.addLineListener(new LineListener()
        {
            @Override
            public void update(LineEvent event)
            {
                if (event.getType() == LineEvent.Type.STOP)
                    clip.close();
            }
        });

        clip.open(AudioSystem.getAudioInputStream(file));
        clip.start();
    }
    catch (Exception exc)
    {
        exc.printStackTrace(System.out);
    }
}

I recently found out that :active:focus does the same thing in css as :active:hover if you need to override a custom css library, they might use both.

With the Return statement from the proc, I needed to assign the temp variable and pass it to another stored procedure. The value was getting assigned fine but when passing it as a parameter, it lost the value. I had to create a temp table and set the variable from the table (SQL 2008)

From this: 
declare @anID int
exec @anID = dbo.StoredProc_Fetch @ID, @anotherID, @finalID
exec dbo.ADifferentStoredProc @anID (no value here)

To this:
declare @t table(id int) 
declare @anID int
insert into @t exec dbo.StoredProc_Fetch @ID, @anotherID, @finalID
set @anID= (select Top 1 * from @t)

Replacing the \n or the escaped <br/> does the trick while keeping the rest of the HTML escaped:

$(document).tooltip({
    content: function() {
        var title = $(this).attr("title") || "";
        return $("<a>").text(title).html().replace(/&lt;br *\/?&gt;/, "<br/>");
    },
});

I found the solution of this problem and i should work i'm sure about this because i also face the same problem

here is my solution----->

var request = require('request');

//set url
var url = 'http://localhost:8088/example';

//set header
var headers = {
    'Authorization': 'Your authorization'
};

//set form data
var form = {first_name: first_name, last_name: last_name};

//set request parameter
request.post({headers: headers, url: url, form: form, method: 'POST'}, function (e, r, body) {

    var bodyValues = JSON.parse(body);
    res.send(bodyValues);
});

For me, It's working like this one.

C:\Program Files\PostgreSQL\12\bin> psql -U postgres -p 5432  -d dummy -f C:\Users\Downloads\d2cm_test.sql

You should pass utf8 encoded string in json_encode. You can use utf8_encode and array_map() function like below:

<?php
    $encoded_rows = array_map('utf8_encode', $rows);
    echo json_encode($encoded_rows);
?>

You should not include commands.c in your header file. In general, you should not include .c files. Rather, commands.c should include commands.h. As defined here, the C preprocessor is inserting the contents of commands.c into commands.h where the include is. You end up with two definitions of f123 in commands.h.

commands.h

#ifndef COMMANDS_H_
#define COMMANDS_H_

void f123();

#endif

commands.c

#include "commands.h"

void f123()
{
    /* code */
}

Functional Component

Actually, for functional component the best practice is like below, I create a sample Spinner component:

import React from 'react';
import { ActivityIndicator } from 'react-native';
import { colors } from 'helpers/theme';
import type { FC } from 'types';

interface SpinnerProps {
  color?: string;
  size?: 'small' | 'large' | 1 | 0;
  animating?: boolean;
  hidesWhenStopped?: boolean;
}

const Spinner: FC<SpinnerProps> = ({
  color,
  size,
  animating,
  hidesWhenStopped,
}) => (
  <ActivityIndicator
    color={color}
    size={size}
    animating={animating}
    hidesWhenStopped={hidesWhenStopped}
  />
);

Spinner.defaultProps = {
  animating: true,
  color: colors.primary,
  hidesWhenStopped: true,
  size: 'small',
};

export default Spinner;

#include <stdio.h>

int main(void)
{
    int number = 7; /* signed */
    int vbool[8 * sizeof(int)];
    int i;
        for (i = 0; i < 8 * sizeof(int); i++)
        {
            vbool[i] = number<<i < 0;   
            printf("%d", vbool[i]);
        }
    return 0;
}

In Kotlin we can do in one line

 TEXT_VIEW_ID.typeface = Typeface.defaultFromStyle(Typeface.BOLD)

If any exception occurs, the transaction will rollback automatically.

Laravel Basic transaction format

    try{
    DB::beginTransaction();

    /* 
    * SQL operation one 
    * SQL operation two
    ..................     
    ..................     
    * SQL operation n */


    DB::commit();
   /* Transaction successful. */
}catch(\Exception $e){       

    DB::rollback();
    /* Transaction failed. */
}

You could use an IN clause

Something like

SELECT
  status,
  CASE
    WHEN STATUS IN('a1','a2','a3')
    THEN 'Active'
    WHEN STATUS = 'i'
    THEN 'Inactive'
    WHEN STATUS = 't'
    THEN 'Terminated'
  END AS STATUSTEXT
FROM
  STATUS

instead

   <meta-data
        android:name="onesignal_google_project_number"
        android:value="@string/google_project_number" />

Hope it helps!!

For those new to Java and wondering why Jiri's answer doesn't work, make sure you do what he says and handle the exception or else it won't compile. Here's the bare minimum:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class ReadFile {

    public static void main(String args[]) throws IOException {
        BufferedReader br = new BufferedReader(new FileReader("test.txt"));
        for (String line; (line = br.readLine()) != null;) {
            System.out.print(line);
        }
        br.close()
    }
}

Here I am going to explain not only the GROUP clause use, but also the Aggregate functions use.

The GROUP BY clause is used in conjunction with the aggregate functions to group the result-set by one or more columns. e.g.:

-- GROUP BY with one parameter:
SELECT column_name, AGGREGATE_FUNCTION(column_name)
FROM table_name
WHERE column_name operator value
GROUP BY column_name;

-- GROUP BY with two parameters:
SELECT
    column_name1,
    column_name2,
    AGGREGATE_FUNCTION(column_name3)
FROM
    table_name
GROUP BY
    column_name1,
    column_name2;

Remember this order:

1. SELECT (is used to select data from a database)

2. FROM (clause is used to list the tables)

3. WHERE (clause is used to filter records)

4. GROUP BY (clause can be used in a SELECT statement to collect data across multiple records and group the results by one or more columns)

5. HAVING (clause is used in combination with the GROUP BY clause to restrict the groups of returned rows to only those whose the condition is TRUE)

6. ORDER BY (keyword is used to sort the result-set)

You can use all of these if you are using aggregate functions, and this is the order that they must be set, otherwise you can get an error.

Aggregate Functions are:

MIN() returns the smallest value in a given column

MAX() returns the maximum value in a given column.

SUM() returns the sum of the numeric values in a given column

AVG() returns the average value of a given column

COUNT() returns the total number of values in a given column

COUNT(*) returns the number of rows in a table

SQL script examples about using aggregate functions:

Let's say we need to find the sale orders whose total sale is greater than $950. We combine the HAVING clause and the GROUP BY clause to accomplish this:

SELECT 
    orderId, SUM(unitPrice * qty) Total
FROM
    OrderDetails
GROUP BY orderId
HAVING Total > 950;

Counting all orders and grouping them customerID and sorting the result ascendant. We combine the COUNT function and the GROUP BY, ORDER BY clauses and ASC:

SELECT 
    customerId, COUNT(*)
FROM
    Orders
GROUP BY customerId
ORDER BY COUNT(*) ASC;

Retrieve the category that has an average Unit Price greater than $10, using AVG function combine with GROUP BY and HAVING clauses:

SELECT 
    categoryName, AVG(unitPrice)
FROM
    Products p
INNER JOIN
    Categories c ON c.categoryId = p.categoryId
GROUP BY categoryName
HAVING AVG(unitPrice) > 10;

Getting the less expensive product by each category, using the MIN function in a subquery:

SELECT categoryId,
       productId,
       productName,
       unitPrice
FROM Products p1
WHERE unitPrice = (
                SELECT MIN(unitPrice)
                FROM Products p2
                WHERE p2.categoryId = p1.categoryId)

The following statement groups rows with the same values in both categoryId and productId columns:

SELECT 
    categoryId, categoryName, productId, SUM(unitPrice)
FROM
    Products p
INNER JOIN
    Categories c ON c.categoryId = p.categoryId
GROUP BY categoryId, productId

I extended the getArgs function just to get also commands, as well as flags (-f, --anotherflag) and named args (--data=blablabla):

1. The module

/**
 * @module getArgs.js
 * get command line arguments (commands, named arguments, flags)
 *
 * @see https://stackoverflow.com/a/54098693/1786393
 *
 * @return {Object}
 *
 */
function getArgs () {
  const commands = []
  const args = {}
  process.argv
    .slice(2, process.argv.length)
    .forEach( arg => {
      // long arg
      if (arg.slice(0,2) === '--') {
        const longArg = arg.split('=')
        const longArgFlag = longArg[0].slice(2,longArg[0].length)
        const longArgValue = longArg.length > 1 ? longArg[1] : true
        args[longArgFlag] = longArgValue
     }
     // flags
      else if (arg[0] === '-') {
        const flags = arg.slice(1,arg.length).split('')
        flags.forEach(flag => {
          args[flag] = true
        })
      }
     else {
      // commands
      commands.push(arg)
     } 
    })
  return { args, commands }
}


// test
if (require.main === module) {
  // node getArgs test --dir=examples/getUserName --start=getUserName.askName
  console.log( getArgs() )
}

module.exports = { getArgs }

2. Usage example:

$ node lib/getArgs test --dir=examples/getUserName --start=getUserName.askName
{
  args: { dir: 'examples/getUserName', start: 'getUserName.askName' },
  commands: [ 'test' ]
}

$ node lib/getArgs --dir=examples/getUserName --start=getUserName.askName test tutorial
{
  args: { dir: 'examples/getUserName', start: 'getUserName.askName' },
  commands: [ 'test', 'tutorial' ]
}

// Fill it with numbers using a for-loop for (int i = 0; i < nums.length; i++)

{ 
     nums[i] = i + 1;
    sum += n;
}

System.out.println(sum);

Adding on to what @tjg184 said, you could do something like...

if (String.IsNullOrEmpty(MaterialTextBox.Text.Trim())) 

...

It partly depends on which overload you're talking about, but the basic idea is:

• Start with a seed as the "current value"
• Iterate over the sequence. For each value in the sequence:
  • Apply a user-specified function to transform (currentValue, sequenceValue) into (nextValue)
  • Set currentValue = nextValue
• Return the final currentValue

You may find the Aggregate post in my Edulinq series useful - it includes a more detailed description (including the various overloads) and implementations.

One simple example is using Aggregate as an alternative to Count:

// 0 is the seed, and for each item, we effectively increment the current value.
// In this case we can ignore "item" itself.
int count = sequence.Aggregate(0, (current, item) => current + 1);

Or perhaps summing all the lengths of strings in a sequence of strings:

int total = sequence.Aggregate(0, (current, item) => current + item.Length);

Personally I rarely find Aggregate useful - the "tailored" aggregation methods are usually good enough for me.

If you develop in Visual Studio 2013 and 2015 versions, you can use their GPU Usage tool:

• GPU Usage Tool in Visual Studio (video) https://www.youtube.com/watch?v=Gjc5bPXGkTE
• GPU Usage Visual Studio 2015 https://msdn.microsoft.com/en-us/library/mt126195.aspx
• GPU Usage tool in Visual Studio 2013 Update 4 CTP1 (blog) http://blogs.msdn.com/b/vcblog/archive/2014/09/05/gpu-usage-tool-in-visual-studio-2013-update-4-ctp1.aspx
• GPU Usage for DirectX in Visual Studio (blog) http://blogs.msdn.com/b/ianhu/archive/2014/12/16/gpu-usage-for-directx-in-visual-studio.aspx

Screenshot from MSDN:

Moreover, it seems you can diagnose any application with it, not only Visual Studio Projects:

In addition to Visual Studio projects you can also collect GPU usage data on any loose .exe applications that you have sitting around. Just open the executable as a solution in Visual Studio and then start up a diagnostics session and you can target it with GPU usage. This way if you are using some type of engine or alternative development environment you can still collect data on it as long as you end up with an executable.

<context:component-scan base-package="package name" />:

This is used to tell the container that there are bean classes in my package scan those bean classes. In order to scan bean classes by container on top of the bean we have to write one of the stereo type annotation like following.

@Component, @Service, @Repository, @Controller

<context:annotation-config />:

If we don't want to write bean tag explicitly in XML then how the container knows if there is a auto wiring in the bean. This is possible by using @Autowired annotation. we have to inform to the container that there is auto wiring in my bean by context:annotation-config.

Great question and great idea, but in SQL you'll need to do this:

For data type datetime, something like this-

declare @BeginDate    datetime = '1/1/2016',
        @EndDate      datetime = '12/1/2016'
create table #months (dates datetime)
declare @var datetime = @BeginDate
   while @var < dateadd(MONTH, +1, @EndDate)
   Begin
          insert into #months Values(@var)
          set @var = Dateadd(MONTH, +1, @var)
   end

If all you really want is numbers, do this-

create table #numbas (digit int)
declare @var int = 1        --your starting digit
    while @var <= 12        --your ending digit
    begin
        insert into #numbas Values(@var)
        set @var = @var +1
    end

just in case you are using a remote access and want to dump all database data, you can use:

pg_dump -a -h your_host -U your_user -W -Fc your_database > DATA.dump

it will create a dump with all database data and use

pg_restore -a -h your_host -U your_user -W -Fc your_database < DATA.dump

to insert the same data in your data base considering you have the same structure

Command:

grep -rl --include="*.js" "searchString" ${PWD}

Returned output:

/root/test/bas.js

numpy.linspace() gives you a one-dimensional NumPy array. For example:

>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([  1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.])

Therefore:

for index,point in my_array

cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:

>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])

Now you can do this:

>>> for x, y in two_d:
    print(x, y)

1 2
4 5

The previous answers are fine, just adding my preferred way of handling this:

var timePortion = myDate.getTime() % (3600 * 1000 * 24);
var dateOnly = new Date(myDate - timePortion);

If you start with a string, you first need to parse it like so:

var myDate = new Date(dateString);

And if you come across timezone related problems as I have, this should fix it:

var timePortion = (myDate.getTime() - myDate.getTimezoneOffset() * 60 * 1000) % (3600 * 1000 * 24);

The accepted answer didn't work for me but the following did:

>PsExec.exe \\<SERVER FQDN> -u <DOMAIN\USER> -p <PASSWORD> /accepteula cmd 
    /c "powershell -noninteractive -command gci c:\"

Example from here

I guess you want to do this:

$total_rating_count = count($total_rating_count);
if ($total_rating_count > 0) // because you can't divide through zero
   $avg = round($total_rating_points / $total_rating_count, 1);

I fully agree with the Key error comments. You could also use the dictionary's get() method as well to avoid the exceptions. This could also be used to give a default path rather than None as shown below.

>>> d = {"a":1, "b":2}
>>> x = d.get("A",None)
>>> print x
None

If you're using Building Standalone Apps with Expo, the versionCode error might creep up owing to the fact that the standard app.json config only has a reference to the version property.

I was able to add a versionCode property under android as follows:

Sample App.json

{
  "expo": {
    "sdkVersion": "29.0.0",
    "name": "App Name",
    "version": "1.1.0",
    "slug": "app-name",
    "icon": "src/images/app-icon.png",
    "privacy": "public",
    "android": {
      "package": "com.madhues.app",
      "permissions": [],
      "versionCode": 2 // Notice the versionCode added under android.
    }
  }
}

You need to use JNI.

First of all use create a .dll using visual studio, that call system("cls"). After that use JNI to use this DDL.

I found this article that is nice:

http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=5170&lngWId=2

I have noticed that when intellisence doesn't work for an object there is usually an error somewhere in the class above line you are working on.

The other option is that you didn't instantiated the FileUpload object as an instance variable. make sure the code:

FileUpload fileUpload = new FileUpload();

is not inside a function in your code behind.

You can use setattr

name  = 'varname'
value = 'something'

setattr(self, name, value) #equivalent to: self.varname= 'something'

print (self.varname)
#will print 'something'

But, since you should inform an object to receive the new variable, this only works inside classes or modules.

If you use the JMX provided history of GC runs you can use the same before/after numbers, you just dont have to force a GC.

You just need to keep in mind that those GC runs (typically one for old and one for new generation) are not on regular intervalls, so you need to extract the starttime as well for plotting (or you plot against a sequence number, for most practical purposes that would be enough for plotting).

For example on Oracle HotSpot VM with ParNewGC, there is a JMX MBean called java.lang:type=GarbageCollector,name=PS Scavenge, it has a attribute LastGCInfo, it returns a CompositeData of the last YG scavenger run. It is recorded with duration, absolute startTime and memoryUsageBefore and memoryUsageAfter.

Just use a timer to read that attribute. Whenever a new startTime shows up you know that it describes a new GC event, you extract the memory information and keep polling for the next update. (Not sure if a AttributeChangeNotification somehow can be used.)

Tip: in your timer you might measure the distance to the last GC run, and if that is too long for the resulution of your plotting, you could invoke System.gc() conditionally. But I would not do that in a OLTP instance.

There are a couple of approaches here.

If you want to perform a case-insensitive check for just this instance, do something like the following.

if (referrer.toLowerCase().indexOf("Ral".toLowerCase()) == -1) {
    ...

Alternatively, if you're performing this check regularly, you can add a new indexOf()-like method to String, but make it case insensitive.

String.prototype.indexOfInsensitive = function (s, b) {
    return this.toLowerCase().indexOf(s.toLowerCase(), b);
}

// Then invoke it
if (referrer.indexOfInsensitive("Ral") == -1) { ...

The solution with the /etc/docker/daemon.json file didn't work for me on Ubuntu.

I was able to configure Docker insecure registries on Ubuntu by providing command line options to the Docker daemon in /etc/default/docker file, e.g.:

# /etc/default/docker    
DOCKER_OPTS="--insecure-registry=a.example.com --insecure-registry=b.example.com"

The same way can be used to configure custom directory for docker images and volumes storage, default DNS servers, etc..

Now, after the Docker daemon has restarted (after executing sudo service docker restart), running docker info will show:

Insecure Registries:
  a.example.com
  b.example.com
  127.0.0.0/8

The short answer

Use one of these two methods:

• Class.getResource(String)
• Class.getResourceAsStream(String)

For example:

InputStream inputStream = YourClass.class.getResourceAsStream("image.jpg");

--

The long answer

Typically, one would not want to load files using absolute paths. For example, don’t do this if you can help it:

File file = new File("C:\\Users\\Joe\\image.jpg");

This technique is not recommended for at least two reasons. First, it creates a dependency on a particular operating system, which prevents the application from easily moving to another operating system. One of Java’s main benefits is the ability to run the same bytecode on many different platforms. Using an absolute path like this makes the code much less portable.

Second, depending on the relative location of the file, this technique might create an external dependency and limit the application’s mobility. If the file exists outside the application’s current directory, this creates an external dependency and one would have to be aware of the dependency in order to move the application to another machine (error prone).

Instead, use the getResource() methods in the Class class. This makes the application much more portable. It can be moved to different platforms, machines, or directories and still function correctly.

Here is the snippets from my code.. If it solves your problems..

Client Code :

Set jsonpCallBack : 'photos' and dataType:'jsonp'

 $('document').ready(function() {
            var pm_url = 'http://localhost:8080/diztal/rest/login/test_cor?sessionKey=4324234';
            $.ajax({
                crossDomain: true,
                url: pm_url,
                type: 'GET',
                dataType: 'jsonp',
                jsonpCallback: 'photos'
            });
        });
        function photos (data) {
            alert(data);
            $("#twitter_followers").html(data.responseCode);
        };

Server Side Code (Using Rest Easy)

@Path("/test_cor")
@GET
@Produces(MediaType.TEXT_PLAIN)
public String testCOR(@QueryParam("sessionKey") String sessionKey, @Context HttpServletRequest httpRequest) {
    ResponseJSON<LoginResponse> resp = new ResponseJSON<LoginResponse>();
    resp.setResponseCode(sessionKey);
    resp.setResponseText("Wrong Passcode");
    resp.setResponseTypeClass("Login");
    Gson gson = new Gson();
    return "photos("+gson.toJson(resp)+")"; // CHECK_THIS_LINE
}

This looks like a behavior difference in the handling of \s between grep 2.5 and newer versions (a bug in old grep?). I confirm your result with grep 2.5.4, but all four of your greps do work when using grep 2.6.3 (Ubuntu 10.10).

Note:

GNU grep 2.5.4
echo "foo bar" | grep "\s"
   (doesn't match)

whereas

GNU grep 2.6.3
echo "foo bar" | grep "\s"
foo bar

Probably less trouble (as \s is not documented):

Both GNU greps
echo "foo bar" | grep "[[:space:]]"
foo bar

My advice is to avoid using \s ... use [ \t]* or [[:space:]] or something like it instead.

Like so?

>>>> [path for path in os.listdir(os.getcwd()) if os.path.isdir(path)]

1.) I need to check if the object is not null; Is the following expression correct;

if (person == null){ }

YES. This is how you check if object is null.

2.) I need to know if the ID contains an Int.

if(person.getId()==null){}

NO Since id is defined as primitive int, it will be default initialized with 0 and it will never be null. There is no need to check primitive types, if they are null. They will never be null. If you want, you can compare against the default value 0 as if(person.getId()==0){}.

# here database details      
mysql_connect('hostname', 'username', 'password');
mysql_select_db('database-name');

$sql = "SELECT username FROM userregistraton";
$result = mysql_query($sql);

echo "<select name='username'>";
while ($row = mysql_fetch_array($result)) {
    echo "<option value='" . $row['username'] ."'>" . $row['username'] ."</option>";
}
echo "</select>";

# here username is the column of my table(userregistration)
# it works perfectly

How about setInterval, to check for complete iteration count, brings guarantee. not sure if it won't overload the scope though but I use it and seems to be the one

_.forEach(actual_JSON, function (key, value) {

     // run any action and push with each iteration 

     array.push(response.id)

});


setInterval(function(){

    if(array.length > 300) {

        callback()

    }

}, 100);

There's a great deal of research on this. Here's a quick summary.

Response Times: The 3 Important Limits

by Jakob Nielsen on January 1, 1993

Summary: There are 3 main time limits (which are determined by human perceptual abilities) to keep in mind when optimizing web and application performance.

Excerpt from Chapter 5 in my book Usability Engineering, from 1993:

The basic advice regarding response times has been about the same for thirty years [Miller 1968; Card et al. 1991]:

• 0.1 second is about the limit for having the user feel that the system is reacting instantaneously, meaning that no special feedback is necessary except to display the result.
• 1.0 second is about the limit for the user's flow of thought to stay uninterrupted, even though the user will notice the delay. Normally, no special feedback is necessary during delays of more than 0.1 but less than 1.0 second, but the user does lose the feeling of operating directly on the data.
• 10 seconds is about the limit for keeping the user's attention focused on the dialogue. For longer delays, users will want to perform other tasks while waiting for the computer to finish, so they should be given feedback indicating when the computer expects to be done. Feedback during the delay is especially important if the response time is likely to be highly variable, since users will then not know what to expect.

jQuery Mobile now has this built in:

<input type="text" name="clear" id="clear-demo" value="" data-clear-btn="true">

Jquery Mobile API TextInput docs

as simple as:

find . -mtime -1 | xargs tar --no-recursion -czf myfile.tgz

where find . -mtime -1 will select all the files in (recursively) current directory modified day before. you can use fractions, for example:

find . -mtime -1.5 | xargs tar --no-recursion -czf myfile.tgz

the below code does exactly what you want

//use this intent on click event

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(cameraIntent,CAMERA_REQUEST);

// the above code is used in 'on activity Result'

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);

    if (requestCode == CAMERA_REQUEST) {
        Bitmap photo = (Bitmap) data.getExtras().get("data");
        image.setImageBitmap(photo);
    }
}

In XSLT the same <xsl:variable> can be declared only once and can be given a value only at its declaration. If more than one variables are declared at the same time, they are in fact different variables and have different scope.

Therefore, the way to achieve the wanted conditional setting of the variable and producing its value is the following:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>

    <xsl:template match="class">
    <xsl:variable name="subexists">
            <xsl:choose>
                <xsl:when test="joined-subclass">true</xsl:when>
                <xsl:otherwise>false</xsl:otherwise>
            </xsl:choose>
        </xsl:variable>
        subexists:  <xsl:text/>    
        <xsl:value-of select="$subexists" />
    </xsl:template>
</xsl:stylesheet>

When the above transformation is applied on the following XML document:

<class>
 <joined-subclass/>
</class>

the wanted result is produced:

    subexists:  true

Here's another way that might be faster, in terms of compute time, than iterating. Not sure. The idea is to convert the array to a string, truncate it, and get the size of the new array.

For example, to find the index of 'd':

arr=(a b c d)    
temp=`echo ${arr[@]}`
temp=( ${temp%%d*} )
index=${#temp[@]}

You could turn this into a function like:

get-index() {

    Item=$1
    Array="$2[@]"

    ArgArray=( ${!Array} )
    NewArray=( ${!Array%%${Item}*} )

    Index=${#NewArray[@]}

    [[ ${#ArgArray[@]} == ${#NewArray[@]} ]] && echo -1 || echo $Index

}

You could then call:

get-index d arr

and it would echo back 3, which would be assignable with:

index=`get-index d arr`

When you do self.button = Button(...).grid(...), what gets assigned to self.button is the result of the grid() command, not a reference to the Button object created.

You need to assign your self.button variable before packing/griding it. It should look something like this:

self.button = Button(self,text="Click Me",command=self.color_change,bg="blue")
self.button.grid(row = 2, column = 2, sticky = W)

=COUNTIF(A:A;"lisa")

You can replace the criteria with cell references from Column B

If you only care about the conflict resolution and not about keeping the commit history, the following method should work. Say you want to merge a.py b.py from BRANCHA into BRANCHB. First, make sure any changes in BRANCHB are either committed or stashed away, and that there are no untracked files. Then:

git checkout BRANCHB
git merge BRANCHA
# 'Accept' all changes
git add .
# Clear staging area
git reset HEAD -- .
# Stash only the files you want to keep
git stash push a.py b.py
# Remove all other changes
git add .
git reset --hard
# Now, pull the changes
git stash pop

git won't recognize that there are conflicts in a.py b.py, but the merge conflict markers are there if there were in fact conflicts. Using a third-party merge tool, such as VSCode, one will be able to resolve conflicts more comfortably.

I have nice solution that i would like to share. First you need to detect if user is on mobile like this:

var touchDevice = /ipad|iphone|android|windows phone|blackberry/i.test(navigator.userAgent.toLowerCase());

Then just add:

if (!touchDevice) {
    $(".navbar-ul").addClass("hoverable");
}

And in CSS:

.navbar-ul.hoverable li a:hover {
    color: #fff;
}

As well as find listed in other answers, better shells allow both recurvsive globs and filtering of glob matches, so in zsh for example...

ls -lad **/*(/)

...lists all directories while keeping all the "-l" details that you want, which you'd otherwise need to recreate using something like...

find . -type d -exec ls -ld {} \;

(not quite as easy as the other answers suggest)

The benefit of find is that it's more independent of the shell - more portable, even for system() calls from within a C/C++ program etc..

IF "%1"=="" will fail, all versions of this will fail under certain poison character conditions. Only IF DEFINED or IF NOT DEFINED are safe

string currentDirectory = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
string archiveFolder = Path.Combine(currentDirectory, "archive");

The first parameter is the path. The second is the search pattern you want to use.

Here are the steps:

• Install the subclipse plugin (provides svn connectivity in eclipse) and connect to the repository. Instructions here: http://subclipse.tigris.org/install.html
• Go to File->New->Other->Under the SVN category, select Checkout Projects from SVN.
• Select your project's root folder and select checkout as a project in the workspace.

It seems you are checking the .project file into the source repository. I would suggest not checking in the .project file so users can have their own version of the file. Also, if you use the subclipse plugin it allows you to check out and configure a source folder as a java project. This process creates the correct .project for you(with the java nature),

Libman seems to be the tool preferred by Microsoft now. It is integrated in Visual Studio 2017(15.8).

This article describes how to use it and even how to set up a restore performed by the build process.

Bootstrap's documentation tells you what files you need in your project.

The following example should work as a configuration for libman.json.

{
  "version": "1.0",
  "defaultProvider": "cdnjs",
  "libraries": [
  {
    "library": "[email protected]",
    "destination": "wwwroot/lib/bootstrap",
    "files": [
    "js/bootstrap.bundle.js",
    "css/bootstrap.min.css"
    ]
  },
  {
    "library": "[email protected]",
    "destination": "wwwroot/lib/jquery",
    "files": [
      "jquery.min.js"
    ]
  }
]
}

It's a bad idea to change the behavior of the home key. This is why Google doesn't allow you to override the home key. I wouldn't mess with the home key generally speaking. You need to give the user a way to get out of your app if it goes off into the weeds for whatever reason.

I'd image any work around will have unwanted side effects.

There is no extension methods in Java, but you can have it by manifold as below,

You define "echo" method for strings by below sample,

@Extension
public class MyStringExtension {
    public static void echo(@This String thiz) {
        System.out.println(thiz);
    }
}

And after that, you can use this method (echo) for strings anywhere like,

"Hello World".echo();   //prints "Hello World"
"Welcome".echo();       //prints "Welcome"
String name = "Jonn";
name.echo();            //prints "John"

You can also, of course, have parameters like,

@Extension
public class MyStringExtension {
    public static void echo(@This String thiz, String suffix) {
        System.out.println(thiz + " " + suffix);
    }
}

And use like this,

"Hello World".echo("programming");   //prints "Hello World programming"
"Welcome".echo("2021");              //prints "Welcome 2021"
String name = "Jonn";

I don't like to force interrupt my async tasks with cancel(true) unnecessarily because they may have resources to be freed, such as closing sockets or file streams, writing data to the local database etc. On the other hand, I have faced situations in which the async task refuses to finish itself part of the time, for example sometimes when the main activity is being closed and I request the async task to finish from inside the activity's onPause() method. So it's not a matter of simply calling running = false. I have to go for a mixed solution: both call running = false, then giving the async task a few milliseconds to finish, and then call either cancel(false) or cancel(true).

if (backgroundTask != null) {
    backgroundTask.requestTermination();
    try {
        Thread.sleep((int)(0.5 * 1000));
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    if (backgroundTask.getStatus() != AsyncTask.Status.FINISHED) {
        backgroundTask.cancel(false);
    }
    backgroundTask = null;
}

As a side result, after doInBackground() finishes, sometimes the onCancelled() method is called, and sometimes onPostExecute(). But at least the async task termination is guaranteed.

A char is actually a numeric datatype - you can add one to an int, for example. It's an unsigned short (16 bits). In that regard you can just cast the output to, say, an int to get the numeric value.

However you need to think a little more about what it is you're asking - not all characters are ASCII values. What output do you expect for â, for example, or ??

Moreover, why do you want this? In this day and age you ought to be thinking about Unicode, not ASCII. If you let people know what your goal is, and how you intend to use this returned value, we can almost certainly let you know of a better way to achieve it.

Use:

android:screenOrientation="portrait" 

Just write this line in your application's manifest file in each activity which you want to show in portrait mode only.

You can easily append to the end of a file, by using the redirection char twice (>>).

This will copy source.txt to destination.txt, overwriting destination in the process:

type source.txt > destination.txt

This will copy source.txt to destination.txt, appending to destination in the process:

type source.txt >> destination.txt

I worked on both Travis and Jenkins: I will list down some of the features of both:

Setup CI for a project

Travis comes in first place. It's very easy to setup. Takes less than a minute to setup with GitHub.

1. Login to GitHub
2. Create Web Hook for Travis.
3. Return to Travis, and login with your GitHub credentials
4. Sync your GitHub repo and enable Push and Pull requests.

Jenkins:

1. Create an Environment (Master Jenkins)
2. Create web hooks
3. Configure each job (takes time compare to Travis)

Re-running builds

Travis: Anyone with write access on GitHub can re-run the build by clicking on `restart build

Jenkins: Re-run builds based on a phrase. You provide phrase text in PR/commit description, like reverify jenkins.

Controlling environment

Travis: Travis provides hosted environment. It installs required software for every build. It’s a time-consuming process.

Jenkins: One-time setup. Installs all required software on a node/slave machine, and then builds/tests on a pre-installed environment.

Build Logs:

Travis: Supports build logs to place in Amazon S3.

Jenkins: Easy to setup with build artifacts plugin.

This will flatten a list or dictionary (or list of lists or dictionaries of dictionaries etc). It assumes that the values are strings and it creates a string that concatenates each item with a separator argument. If you wanted you could use the separator to split the result into a list object afterward. It uses recursion if the next value is a list or a string. Use the key argument to tell whether you want the keys or the values (set key to false) from the dictionary object.

def flatten_obj(n_obj, key=True, my_sep=''):
    my_string = ''
    if type(n_obj) == list:
        for val in n_obj:
            my_sep_setter = my_sep if my_string != '' else ''
            if type(val) == list or type(val) == dict:
                my_string += my_sep_setter + flatten_obj(val, key, my_sep)
            else:
                my_string += my_sep_setter + val
    elif type(n_obj) == dict:
        for k, v in n_obj.items():
            my_sep_setter = my_sep if my_string != '' else ''
            d_val = k if key else v
            if type(v) == list or type(v) == dict:
                my_string += my_sep_setter + flatten_obj(v, key, my_sep)
            else:
                my_string += my_sep_setter + d_val
    elif type(n_obj) == str:
        my_sep_setter = my_sep if my_string != '' else ''
        my_string += my_sep_setter + n_obj
        return my_string
    return my_string

print(flatten_obj(['just', 'a', ['test', 'to', 'try'], 'right', 'now', ['or', 'later', 'today'],
                [{'dictionary_test': 'test'}, {'dictionary_test_two': 'later_today'}, 'my power is 9000']], my_sep=', ')

yields:

just, a, test, to, try, right, now, or, later, today, dictionary_test, dictionary_test_two, my power is 9000

Try escaping the single quote with a single quote:

Replace(@strip, '''', '')

var scrollBottom = $(window).scrollTop() + $(window).height();

here is my two cents. In comparisson to other solutions, one does not need to add extra containers. Therefor this solution is a bit more elegant. Beneath the code example i'll explain why this works.

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title>test</title>
        <style>

            html
            {
                height:100%;
            }

            body
            {
                min-height:100%;
                padding:0; /*not needed, but otherwise header and footer tags have padding and margin*/
                margin:0; /*see above comment*/
            }

            body
            {
                position:relative;
                padding-bottom:60px; /* Same height as the footer. */           
            }

            footer
            {
                position:absolute;
                bottom:0px;
                height: 60px;

                background-color: red;
            }

        </style>
    </head>
    <body>
        <header>header</header>


        <footer>footer</footer>
    </body>
</html>

So the first thing we do, is make the biggest container( html ) 100%. The html page is as big as the page itself. Next we set the body height, it can be bigger than the 100% of the html tag, but it should at least be as big, therefore we use min-height 100%.

We also make the body relative. Relative means you can move the block element around relative from its original position. We don't use that here though. Because relative has a second use. Any absolute element is either absolute to the root (html) or to the first relative parent/grandparent. That's what we want, we want the footer to be absolute, relative to the body, namely the bottom.

The last step is to set the footer to absolute and bottom:0, which moves it to the bottom of the first parent/grandparent that is relative ( body ofcourse ).

Now we still have one problem to fix, when we fill the complete page, the content goes beneath the footer. Why? well, because the footer is no longer inside the "html flow", because it is absolute. So how do we fix this? We will add padding-bottom to the body. This makes sure the body is actually bigger than it's content.

I hope i made a lot clear for you guys.

if you need double quoted JSON use JSON.stringify( object)

var $items = $('#firstName, #lastName,#phoneNumber,#address ')
var obj = {}
$items.each(function() {
    obj[this.id] = $(this).val();
})

var json= JSON.stringify( obj);

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

Use Activity.getWindow() to get the window of your activity; use Window.addFlags() to add whichever of the following flags in WindowManager.LayoutParams that you desire:

• FLAG_DISMISS_KEYGUARD

• FLAG_SHOW_WHEN_LOCKED

• FLAG_TURN_SCREEN_ON

It's in the python docs.

import datetime
datetime.datetime.combine(datetime.date(2011, 1, 1), 
                          datetime.time(10, 23))

returns

datetime.datetime(2011, 1, 1, 10, 23)

I upgraded from Newtonsoft.Json 11.0.1 to 12.0.2. Opening the project file in Notepad++ I discovered both

<Reference Include="Newtonsoft.Json, Version=12.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed, processorArchitecture=MSIL">
      <HintPath>..\packages\Newtonsoft.Json.12.0.2\lib\net45\Newtonsoft.Json.dll</HintPath>
    </Reference>

and

<ItemGroup>
    <Reference Include="Newtonsoft.Json">
      <HintPath>..\packages\Newtonsoft.Json.11.0.1\lib\net45\Newtonsoft.Json.dll</HintPath>
    </Reference>
  </ItemGroup>

I deleted the ItemGroup wrapping the reference with the hint path to version 11.0.1.

These issues can be insanely frustrating to find. What's more, developers often follow the same steps as previous project setups. The prior setups didn't encounter the issue. For whatever reason the project file occasionally is updated incorrectly.

I desperately wish Microsoft would fix these visual studio DLL hell issues from popping up. It happens far too often and causing progress to screech to a halt until it is fixed, often by trial and error.

int sum = 0;
for(int i = 0; i < A.length; i++){
  sum += A[i];
