var myCallback = function(data) {
  console.log('got data: '+data);
};

var usingItNow = function(callback) {
  callback('get it?');
};

Now open node or browser console and paste the above definitions.

Finally use it with this next line:

usingItNow(myCallback);

With Respect to the Node-Style Error Conventions

Costa asked what this would look like if we were to honor the node error callback conventions.

In this convention, the callback should expect to receive at least one argument, the first argument, as an error. Optionally we will have one or more additional arguments, depending on the context. In this case, the context is our above example.

Here I rewrite our example in this convention.

var myCallback = function(err, data) {
  if (err) throw err; // Check for the error and throw if it exists.
  console.log('got data: '+data); // Otherwise proceed as usual.
};

var usingItNow = function(callback) {
  callback(null, 'get it?'); // I dont want to throw an error, so I pass null for the error argument
};

If we want to simulate an error case, we can define usingItNow like this

var usingItNow = function(callback) {
  var myError = new Error('My custom error!');
  callback(myError, 'get it?'); // I send my error as the first argument.
};

The final usage is exactly the same as in above:

usingItNow(myCallback);

The only difference in behavior would be contingent on which version of usingItNow you've defined: the one that feeds a "truthy value" (an Error object) to the callback for the first argument, or the one that feeds it null for the error argument.

Here is an extension method that will convert an object to a ViewDataDictionary.

public static ViewDataDictionary ToViewDataDictionary(this object values)
{
    var dictionary = new ViewDataDictionary();
    foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(values))
    {
        dictionary.Add(property.Name, property.GetValue(values));
    }
    return dictionary;
}

You can then use it in your view like so:

@Html.Partial("_MyPartial", new
{
    Property1 = "Value1",
    Property2 = "Value2"
}.ToViewDataDictionary())

Which is much nicer than the new ViewDataDictionary { { "Property1", "Value1" } , { "Property2", "Value2" }} syntax.

Then in your partial view, you can use ViewBag to access the properties from a dynamic object rather than indexed properties, e.g.

<p>@ViewBag.Property1</p>
<p>@ViewBag.Property2</p>

I ran into a similar situation trying to convert a table with several 100k rows with a C++ program (MFC/ODBC).

Since this operation took a very long time, I figured bundling multiple inserts into one (up to 1000 due to MSSQL limitations). My guess that a lot of single insert statements would create an overhead similar to what is described here.

However, it turns out that the conversion took actually quite a bit longer:

        Method 1       Method 2     Method 3 
        Single Insert  Multi Insert Joined Inserts
Rows    1000           1000         1000
Insert  390 ms         765 ms       270 ms
per Row 0.390 ms       0.765 ms     0.27 ms

So, 1000 single calls to CDatabase::ExecuteSql each with a single INSERT statement (method 1) are roughly twice as fast as a single call to CDatabase::ExecuteSql with a multi-line INSERT statement with 1000 value tuples (method 2).

Update: So, the next thing I tried was to bundle 1000 separate INSERT statements into a single string and have the server execute that (method 3). It turns out this is even a bit faster than method 1.

Edit: I am using Microsoft SQL Server Express Edition (64-bit) v10.0.2531.0

Import namespace :

using System.Configuration;

Create ConfigurationElement Company :

public class Company : ConfigurationElement
{

        [ConfigurationProperty("name", IsRequired = true)]
        public string Name
        {
            get
            {
                return this["name"] as string;

                return this["code"] as string;
            }
        }
}

ConfigurationElementCollection:

public class Companies
        : ConfigurationElementCollection
    {
        public Company this[int index]
        {
            get
            {
                return base.BaseGet(index) as Company ;
            }

                {
                    base.BaseRemoveAt(index);
                }
                this.BaseAdd(index, value);
            }
        }

       public new Company this[string responseString]
       {

        protected override object GetElementKey(System.Configuration.ConfigurationElement element)
        {
            return ((Company)element).Name;
        }
    }

and ConfigurationSection:

public class RegisterCompaniesConfig
        : ConfigurationSection
    {

        public static RegisterCompaniesConfig GetConfig()
        {
            return (RegisterCompaniesConfig)System.Configuration.ConfigurationManager.GetSection("RegisterCompanies") ?? new RegisterCompaniesConfig();
        }

        [System.Configuration.ConfigurationProperty("Companies")]
            [ConfigurationCollection(typeof(Companies), AddItemName = "Company")]
        public Companies Companies
        {
            get
            {
                object o = this["Companies"];
                return o as Companies ;
            }
        }

    }

and you must also register your new configuration section in web.config (app.config):

<configuration>       
    <configSections>
          <section name="Companies" type="blablabla.RegisterCompaniesConfig" ..>

then you load your config with

var config = RegisterCompaniesConfig.GetConfig();
foreach(var item in config.Companies)
{
   do something ..
}

Here's a python way. Note: this isn't really that "pythonic" but it demonstrates the algorithm.

def IsPalindromeString(n):
    myLen = len(n)
    i = 0
    while i <= myLen/2:
        if n[i] != n[myLen-1-i]:
            return False
        i += 1
    return True

Go to USB Debugging and disable MIUI Inspection and allow the phone to reboot. Things should be fine from here

Normally Python throws NameError if the variable is not defined:

>>> d[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined

However, you've managed to stumble upon a name that already exists in Python.

Because dict is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.

The type of dict is a type. All types are objects in Python. Thus you are actually trying to index into the type object. This is why the error message says that the "'type' object is not subscriptable."

>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable

Note that you can blindly assign to the dict name, but you really don't want to do that. It's just going to cause you problems later.

>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'

The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:

d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))

The SSL is not properly configured. Those trustAnchor errors usually mean that the trust store cannot be found. Check your configuration and make sure you are actually pointing to the trust store and that it is in place.

Make sure you have a -Djavax.net.ssl.trustStore system property set and then check that the path actually leads to the trust store.

You can also enable SSL debugging by setting this system property -Djavax.net.debug=all. Within the debug output you will notice it states that it cannot find the trust store.

Since git 1.8.5 (Q4 2013):

"git fetch" (hence "git pull" as well) learned to check "fetch.prune" and "remote.*.prune" configuration variables and to behave as if the "--prune" command line option was given.

That means that, if you set remote.origin.prune to true:

git config remote.origin.prune true

Any git fetch or git pull will automatically prune.

Note: Git 2.12 (Q1 2017) will fix a bug related to this configuration, which would make git remote rename misbehave.
See "How do I rename a git remote?".

See more at commit 737c5a9:

Without "git fetch --prune", remote-tracking branches for a branch the other side already has removed will stay forever.
Some people want to always run "git fetch --prune".

To accommodate users who want to either prune always or when fetching from a particular remote, add two new configuration variables "fetch.prune" and "remote.<name>.prune":

• "fetch.prune" allows to enable prune for all fetch operations.
• "remote.<name>.prune" allows to change the behaviour per remote.

The latter will naturally override the former, and the --[no-]prune option from the command line will override the configured default.

Since --prune is a potentially destructive operation (Git doesn't keep reflogs for deleted references yet), we don't want to prune without users consent, so this configuration will not be on by default.

Try it like,

<?php 
    $name='your name';
    echo '<table>
       <tr><th>Name</th></tr>
       <tr><td>'.$name.'</td></tr>
    </table>';
?>

Updated

<?php 
    echo '<table>
       <tr><th>Rst</th><th>Marks</th></tr>
       <tr><td>'.$rst4.'</td><td>'.$marks4.'</td></tr>
    </table>';
?>

YML definition:

dir:
  default: /home/data/in/
  proj1: ${dir.default}p1
  proj2: ${dir.default}p2
  proj3: ${dir.default}p3 

Somewhere in thymeleaf

<p th:utext='${@environment.getProperty("dir.default")}' />
<p th:utext='${@environment.getProperty("dir.proj1")}' /> 

Output: /home/data/in/ /home/data/in/p1

I understand the original poster was looking for a simple solution, but unfortunately there really is no simple solution.

Nevertheless, I've recently created an open-source freeware clipping library (written in Delphi, C++ and C#) which clips all kinds of polygons (including self-intersecting ones). This library is pretty simple to use: http://sourceforge.net/projects/polyclipping/ .

There is often the tip to use 'echo.'

But that is slow, and it could fail with an error message, as cmd.exe will search first for a file named 'echo' (without extension) and only when the file doesn't exists it outputs an empty line.

You could use echo(. This is approximately 20 times faster, and it works always. The only drawback could be that it looks odd.

More about the different ECHO:/\ variants is at DOS tips: ECHO. FAILS to give text or blank line.

In the package explorer, in the upper right corner of the view, there is a little down arrow. Tool tip will say view menu. From that menu, select filters

From there, uncheck .* resources.

So Package Explorer -> View Menu -> Filters -> uncheck .* resources.

With Eclipse Kepler and OS X this is a bit different:

Package Explorer -> Customize View -> Filters -> uncheck .* resources

If you want get "insert statement" for your table you can try the following code.

SELECT 
    CONCAT(
        GROUP_CONCAT(
            CONCAT(
                'INSERT INTO `your_table` (`field_1`, `field_2`, `...`, `field_n`) VALUES ("',
                `field_1`,
                '", "',
                `field_2`,
                '", "',
                `...`,
                '", "',
                `field_n`,
                '")'
            ) SEPARATOR ';\n'
        ), ';'
    ) as `QUERY`
FROM `your_table`;

As a result, you will have insers statement:

INSERT INTO your_table (field_1, field_2, ..., field_n) VALUES (value_11, value_12, ... , value_1n);

INSERT INTO your_table (field_1, field_2, ..., field_n) VALUES (value_21, value_22, ... , value_2n);

/...................................................../

INSERT INTO your_table (field_1, field_2, ..., field_n) VALUES (value_m1, value_m2, ... , value_mn);

, where m - number of records in your_table

CSS {vertical-align: top;} or html Attribute {valign="top"}

.table td, 
.table th {
    border: 1px solid #161b21;
    text-align: left;
    padding: 8px;
    width: 250px;
    height: 100px;
    
    /* style for table */
}

.table-body-text {
  vertical-align: top;
}

<table class="table">
    <tr>
      <th valign="top">Title 1</th>
      <th valign="top">Title 2</th>
    </tr>
    <tr>
      <td class="table-body-text">text</td>
      <td class="table-body-text">text</td>
    </tr>
   </table>

For table vertical-align we have 2 options.

1. is to use css {vertical-align: top;}

2. another way is to user attribute "valign" and the property should be "top" {valign="top"}

You can wrap all tasks which can fail in block, and use ignore_errors: yes with that block.

tasks:
  - name: ls
    command: ls -la
  - name: pwd
    command: pwd

  - block:
    - name: ls non-existing txt file
      command: ls -la no_file.txt
    - name: ls non-existing pic
      command: ls -la no_pic.jpg
    ignore_errors: yes 

Read more about error handling in blocks here.

Another cause of "TCP ACKed Unseen" is the number of packets that may get dropped in a capture. If I run an unfiltered capture for all traffic on a busy interface, I will sometimes see a large number of 'dropped' packets after stopping tshark.

On the last capture I did when I saw this, I had 2893204 packets captured, but once I hit Ctrl-C, I got a 87581 packets dropped message. Thats a 3% loss, so when wireshark opens the capture, its likely to be missing packets and report "unseen" packets.

As I mentioned, I captured a really busy interface with no capture filter, so tshark had to sort all packets, when I use a capture filter to remove some of the noise, I no longer get the error.

Write below function to get date in string, convert and return in string format.

getParsedDate(strDate){
    var strSplitDate = String(strDate).split(' ');
    var date = new Date(strSplitDate[0]);
    // alert(date);
    var dd = date.getDate();
    var mm = date.getMonth() + 1; //January is 0!

    var yyyy = date.getFullYear();
    if (dd < 10) {
        dd = '0' + dd;
    }
    if (mm < 10) {
        mm = '0' + mm;
    }
    date =  dd + "-" + mm + "-" + yyyy;
    return date.toString();
}

Print it where you required: Date : {this.getParsedDate(stringDate)}

Since iOS 11, you can use the native framework called PDFKit for displaying and manipulating PDFs.

After importing PDFKit, you should initialize a PDFView with a local or a remote URL and display it in your view.

if let url = Bundle.main.url(forResource: "example", withExtension: "pdf") {
    let pdfView = PDFView(frame: view.frame)
    pdfView.document = PDFDocument(url: url)
    view.addSubview(pdfView)
}

Read more about PDFKit in the Apple Developer documentation.

Open Advanced Mode in the Groupings pane. (Click the arrow to the right of the Column Groups and select Advanced Mode.)

In the Row Groups area (not Column Groups), click on a Static group, which highlights the corresponding textbox in the tablix.

Click through each Static group until it highlights the leftmost column header. This is generally the first Static group listed.

In the properties grid:

• set KeepWithGroup to After
• set RepeatOnNewPage to True for repeating headers
• set FixedData to True for keeping headers visible

I ran into a similar error trying to run rails with postgresql. (I found this SO looking for a solution. Homebrew broke alot of things when it switched to open SSL 1.1.1) The above answers did not work for me (Mac 10.14.6). However, the answer found here did:

brew install --upgrade openssl
brew reinstall postgresql

The issue is that you are serializing your bean with a custom Gson object while the application is attempting to deserialize your JSON with a Jackson ObjectMapper (within MappingJackson2HttpMessageConverter).

If you open up your server logs, you should see something like

Exception in thread "main" com.fasterxml.jackson.databind.exc.InvalidFormatException: Can not construct instance of java.util.Date from String value '2013-34-10-10:34:31': not a valid representation (error: Failed to parse Date value '2013-34-10-10:34:31': Can not parse date "2013-34-10-10:34:31": not compatible with any of standard forms ("yyyy-MM-dd'T'HH:mm:ss.SSSZ", "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", "EEE, dd MMM yyyy HH:mm:ss zzz", "yyyy-MM-dd"))
 at [Source: java.io.StringReader@baea1ed; line: 1, column: 20] (through reference chain: com.spring.Bean["publicationDate"])

among other stack traces.

One solution is to set your Gson date format to one of the above (in the stacktrace).

The alternative is to register your own MappingJackson2HttpMessageConverter by configuring your own ObjectMapper to have the same date format as your Gson.

This is a mistake:

m.check(side);

That code has to go inside a function. Your class definition can only contain declarations and functions.

Classes don't "run", they provide a blueprint for how to make an object.

The line Message m; means that an Orderbook will contain Message called m, if you later create an Orderbook.

Here is a recursive solution in PHP. WhirlWind's post accurately describes the logic. It's worth mentioning that generating all permutations runs in factorial time, so it might be a good idea to use an iterative approach instead.

public function permute($sofar, $input){
  for($i=0; $i < strlen($input); $i++){
    $diff = strDiff($input,$input[$i]);
    $next = $sofar.$input[$i]; //next contains a permutation, save it
    $this->permute($next, $diff);
  }
}

The strDiff function takes two strings, s1 and s2, and returns a new string with everything in s1 without elements in s2 (duplicates matter). So, strDiff('finish','i') => 'fnish' (the second 'i' is not removed).

You can use array_sum().

$total = array_sum($group);

Accepted answer throws a java.lang.StackOverflowError when calling the setParent or addChild methods.

Here's a slightly simpler implementation without those bugs:

public class MyTreeNode<T>{
    private T data = null;
    private List<MyTreeNode> children = new ArrayList<>();
    private MyTreeNode parent = null;

    public MyTreeNode(T data) {
        this.data = data;
    }

    public void addChild(MyTreeNode child) {
        child.setParent(this);
        this.children.add(child);
    }

    public void addChild(T data) {
        MyTreeNode<T> newChild = new MyTreeNode<>(data);
        this.addChild(newChild);
    }

    public void addChildren(List<MyTreeNode> children) {
        for(MyTreeNode t : children) {
            t.setParent(this);
        }
        this.children.addAll(children);
    }

    public List<MyTreeNode> getChildren() {
        return children;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }

    private void setParent(MyTreeNode parent) {
        this.parent = parent;
    }

    public MyTreeNode getParent() {
        return parent;
    }
}

Some examples:

MyTreeNode<String> root = new MyTreeNode<>("Root");

MyTreeNode<String> child1 = new MyTreeNode<>("Child1");
child1.addChild("Grandchild1");
child1.addChild("Grandchild2");

MyTreeNode<String> child2 = new MyTreeNode<>("Child2");
child2.addChild("Grandchild3");

root.addChild(child1);
root.addChild(child2);
root.addChild("Child3");

root.addChildren(Arrays.asList(
        new MyTreeNode<>("Child4"),
        new MyTreeNode<>("Child5"),
        new MyTreeNode<>("Child6")
));

for(MyTreeNode node : root.getChildren()) {
    System.out.println(node.getData());
}

You can use the -quit option of find:

find <dir> -maxdepth 1 -type d -name '*foo*' -print -quit

Had the same issue with target version 19 on both project.properties and AndroidManifest.xml with Ant.

Fixed it by:

• Uninstalled Android SDK Build-Tools 19.0.1
• Installed Android SDK Build-Tools 19.0.2

I think @Al-Kathiri-Khalid is spot on. The issue is only due to missing support for the API level in Build Tools.

This code creates the file temp.xls in the desktop but it uses the SpecialFolders property, which is very useful sometimes!

set WshShell = WScript.CreateObject("WScript.Shell")
strDesktop = WshShell.SpecialFolders("Desktop")

set objExcel = CreateObject("Excel.Application")
Set objWorkbook = objExcel.Workbooks.Add()
objWorkbook.SaveAs(strDesktop & "\temp.xls")

What you want can be achieved by modifying the hosts file through Fiddler 2 application.

Follow these steps:

1. Install Fiddler2

2. Navigate to Fiddler2 menu:- Tools > HOSTS.. (Click to select)

3. Add a line like this:-

   localhost:8080 www.mydomainname.com

4. Save the file & then checkout www.mydomainname.com in browser.

macOS - revised 2017

IN 2017, the VS CODE keyboard shortcuts have changed to CTRL+1, CTRL+2,CTRL+3 etc..to switch between tabs.

CMD+1, CMD+2, and CMD+3 switch between and create tab groups

As mentioned above:

The GOPATH environment variable specifies the location of your workspace.

For Windows, this worked for me (in Ms-dos window):

set GOPATH=D:\my_folder_for_go_code\

This creates a GOPATH variable that Ms-dos recognizes when used as follows:

cd %GOPATH%

Differentiating between the possible origins of exceptions raised from a compound with statement

Differentiating between exceptions that occur in a with statement is tricky because they can originate in different places. Exceptions can be raised from either of the following places (or functions called therein):

• ContextManager.__init__
• ContextManager.__enter__
• the body of the with
• ContextManager.__exit__

For more details see the documentation about Context Manager Types.

If we want to distinguish between these different cases, just wrapping the with into a try .. except is not sufficient. Consider the following example (using ValueError as an example but of course it could be substituted with any other exception type):

try:
    with ContextManager():
        BLOCK
except ValueError as err:
    print(err)

Here the except will catch exceptions originating in all of the four different places and thus does not allow to distinguish between them. If we move the instantiation of the context manager object outside the with, we can distinguish between __init__ and BLOCK / __enter__ / __exit__:

try:
    mgr = ContextManager()
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        with mgr:
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
    except ValueError as err:
        # At this point we still cannot distinguish between exceptions raised from
        # __enter__, BLOCK, __exit__ (also BLOCK since we didn't catch ValueError in the body)
        pass

Effectively this just helped with the __init__ part but we can add an extra sentinel variable to check whether the body of the with started to execute (i.e. differentiating between __enter__ and the others):

try:
    mgr = ContextManager()  # __init__ could raise
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        entered_body = False
        with mgr:
            entered_body = True  # __enter__ did not raise at this point
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
    except ValueError as err:
        if not entered_body:
            print('__enter__ raised:', err)
        else:
            # At this point we know the exception came either from BLOCK or from __exit__
            pass

The tricky part is to differentiate between exceptions originating from BLOCK and __exit__ because an exception that escapes the body of the with will be passed to __exit__ which can decide how to handle it (see the docs). If however __exit__ raises itself, the original exception will be replaced by the new one. To deal with these cases we can add a general except clause in the body of the with to store any potential exception that would have otherwise escaped unnoticed and compare it with the one caught in the outermost except later on - if they are the same this means the origin was BLOCK or otherwise it was __exit__ (in case __exit__ suppresses the exception by returning a true value the outermost except will simply not be executed).

try:
    mgr = ContextManager()  # __init__ could raise
except ValueError as err:
    print('__init__ raised:', err)
else:
    entered_body = exc_escaped_from_body = False
    try:
        with mgr:
            entered_body = True  # __enter__ did not raise at this point
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
            except Exception as err:  # this exception would normally escape without notice
                # we store this exception to check in the outer `except` clause
                # whether it is the same (otherwise it comes from __exit__)
                exc_escaped_from_body = err
                raise  # re-raise since we didn't intend to handle it, just needed to store it
    except ValueError as err:
        if not entered_body:
            print('__enter__ raised:', err)
        elif err is exc_escaped_from_body:
            print('BLOCK raised:', err)
        else:
            print('__exit__ raised:', err)

Alternative approach using the equivalent form mentioned in PEP 343

PEP 343 -- The "with" Statement specifies an equivalent "non-with" version of the with statement. Here we can readily wrap the various parts with try ... except and thus differentiate between the different potential error sources:

import sys

try:
    mgr = ContextManager()
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        value = type(mgr).__enter__(mgr)
    except ValueError as err:
        print('__enter__ raised:', err)
    else:
        exit = type(mgr).__exit__
        exc = True
        try:
            try:
                BLOCK
            except TypeError:
                pass
            except:
                exc = False
                try:
                    exit_val = exit(mgr, *sys.exc_info())
                except ValueError as err:
                    print('__exit__ raised:', err)
                else:
                    if not exit_val:
                        raise
        except ValueError as err:
            print('BLOCK raised:', err)
        finally:
            if exc:
                try:
                    exit(mgr, None, None, None)
                except ValueError as err:
                    print('__exit__ raised:', err)

Usually a simpler approach will do just fine

The need for such special exception handling should be quite rare and normally wrapping the whole with in a try ... except block will be sufficient. Especially if the various error sources are indicated by different (custom) exception types (the context managers need to be designed accordingly) we can readily distinguish between them. For example:

try:
    with ContextManager():
        BLOCK
except InitError:  # raised from __init__
    ...
except AcquireResourceError:  # raised from __enter__
    ...
except ValueError:  # raised from BLOCK
    ...
except ReleaseResourceError:  # raised from __exit__
    ...

This is an old question, but I just had a similar situation where I needed to check on the status of jobs on SQL Server. A lot of people mentioned the sysjobactivity table and pointed to the MSDN documentation which is great. However, I'd also like to highlight the Job Activity Monitor which provides the status on all jobs that are defined on your server.

With your private key and public certificate, you need to create a PKCS12 keystore first, then convert it into a JKS.

# Create PKCS12 keystore from private key and public certificate.
openssl pkcs12 -export -name myservercert -in selfsigned.crt -inkey server.key -out keystore.p12

# Convert PKCS12 keystore into a JKS keystore
keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert

To verify the contents of the JKS, you can use this command:

keytool -list -v -keystore mykeystore.jks

If this was not a self-signed certificate, you would probably want to follow this step with importing the certificate chain leading up to the trusted CA cert.

Don't be a dumb dumb like me. Was getting the same error as above, NONE of the options in this thread worked. Then I realized I capitalized 'F' in FormGroup. Doh!

Instead Of:

[FormGroup]="form"

Do:

[formGroup]="form"

Well, first you need to select the elements with a function like getElementById.

var targetDiv = document.getElementById("foo").getElementsByClassName("bar")[0];

getElementById only returns one node, but getElementsByClassName returns a node list. Since there is only one element with that class name (as far as I can tell), you can just get the first one (that's what the [0] is for—it's just like an array).

Then, you can change the html with .textContent.

targetDiv.textContent = "Goodbye world!";

var targetDiv = document.getElementById("foo").getElementsByClassName("bar")[0];_x000D_
targetDiv.textContent = "Goodbye world!";

<div id="foo">_x000D_
    <div class="bar">_x000D_
        Hello world!_x000D_
    </div>_x000D_
</div>

Edit the file /etc/postgresql/8.4/main/pg_hba.conf and replace ident or peer by either md5 or trust, depending on whether you want it to ask for a password on your own computer or not. Then reload the configuration file with:

/etc/init.d/postgresql reload

it is because view child require two argument try like this

@ViewChild('nameInput', { static: false, }) nameInputRef: ElementRef;

@ViewChild('amountInput', { static: false, }) amountInputRef: ElementRef;

You can use the isAfter() query function of momentjs:

Check if a moment is after another moment.

moment('2010-10-20').isAfter('2010-10-19'); // true

If you want to limit the granularity to a unit other than milliseconds, pass the units as the second parameter.

moment('2010-10-20').isAfter('2010-01-01', 'year'); // false

moment('2010-10-20').isAfter('2009-12-31', 'year'); // true

http://momentjs.com/docs/#/query/is-after/

echo "<pre>";
print_r($this->session->all_userdata());
echo "</pre>";

Display yet formatting then you can view properly.

If you use Hadoop version 2.6.1 above, while the command works, it complains that its depreciated. I actually could not use the hadoop dfsadmin -safemode leave because I was running Hadoop in a Docker container and that command magically fails when run in the container, so what I did was this. I checked doc and found dfs.safemode.threshold.pct in documentation that says

Specifies the percentage of blocks that should satisfy the minimal replication requirement defined by dfs.replication.min. Values less than or equal to 0 mean not to wait for any particular percentage of blocks before exiting safemode. Values greater than 1 will make safe mode permanent.

so I changed the hdfs-site.xml into the following (In older Hadoop versions, apparently you need to do it in hdfs-default.xml:

<configuration>
    <property>
        <name>dfs.safemode.threshold.pct</name>
        <value>0</value>
    </property>
</configuration>

All you have to do is set you video tag to display:block; FTW the default is inline-block FTL.

Try this

.center {
  margin: 0 auto;
  width: (whatever you want);
  display: block;
}

I've solved that like this:

$RootPath = Split-Path (Split-Path $PSScriptRoot -Parent) -Parent

If you want to add 20% or 30% transparency, you should pre-pend two more characters to the hexadecimal code, like CC.

Note

android:background="#CCFF0088" in XML

where CC is the alpha value, FF is the red factor, 00 is the green factor, and 88 is the blue factor.

Some opacity code:

Hex Opacity Values

100% — FF
95% — F2
90% — E6
85% — D9
80% — CC
75% — BF
70% — B3
65% — A6
60% — 99
55% — 8C
50% — 80
45% — 73
40% — 66
35% — 59
30% — 4D
25% — 40
20% — 33
15% — 26
10% — 1A
5%  — 0D
0% —  00

You can also set opacity programmatically like:

yourView.getBackground().setAlpha(127);

Set opacity between 0 (fully transparent) to 255 (completely opaque). The 127.5 is exactly 50%.

You can create any level of transparency using the given formula. If you want half transparent:

 16 |128          Where 128 is the half of 256.
    |8 -0         So it means 80 is half transparent.

And for 25% transparency:

16 |64            Where 64 is the quarter of 256.
   |4 -0          So it means 40 is quarter transparent.

According to documentation:

random.sample(population, k)

Return a k length list of unique elements chosen from the population sequence. Used for random sampling without replacement.

Basically, it picks k unique random elements, a sample, from a sequence:

>>> import random
>>> c = list(range(0, 15))
>>> c
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14]
>>> random.sample(c, 5)
[9, 2, 3, 14, 11]

random.sample works also directly from a range:

>>> c = range(0, 15)
>>> c
range(0, 15)
>>> random.sample(c, 5)
[12, 3, 6, 14, 10]

In addition to sequences, random.sample works with sets too:

>>> c = {1, 2, 4}
>>> random.sample(c, 2)
[4, 1]

However, random.sample doesn't work with arbitrary iterators:

>>> c = [1, 3]
>>> random.sample(iter(c), 5)
TypeError: Population must be a sequence or set.  For dicts, use list(d).

In C#, you'd do something like this:

MyButton.Attributes.Add("onclick", "put your javascript here including... return false;");

A convenient function for saving plots is ggsave(), which can automatically guess the device type based on the file extension, and smooths over differences between devices. You save with a certain size and units like this:

ggsave("mtcars.png", width = 20, height = 20, units = "cm")

In R markdown, figure size can be specified by chunk:

```{r, fig.width=6, fig.height=4}  
plot(1:5)
```

HTML

<form enctype="multipart/form-data" action="upload.php" method="post">
    <input name="file[]" type="file" />
    <button class="add_more">Add More Files</button>
    <input type="button" value="Upload File" id="upload"/>
</form>

Javascript

 $(document).ready(function(){
    $('.add_more').click(function(e){
        e.preventDefault();
        $(this).before("<input name='file[]' type='file'/>");
    });
});

for ajax upload

$('#upload').click(function() {
    var filedata = document.getElementsByName("file"),
            formdata = false;
    if (window.FormData) {
        formdata = new FormData();
    }
    var i = 0, len = filedata.files.length, img, reader, file;

    for (; i < len; i++) {
        file = filedata.files[i];

        if (window.FileReader) {
            reader = new FileReader();
            reader.onloadend = function(e) {
                showUploadedItem(e.target.result, file.fileName);
            };
            reader.readAsDataURL(file);
        }
        if (formdata) {
            formdata.append("file", file);
        }
    }
    if (formdata) {
        $.ajax({
            url: "/path to upload/",
            type: "POST",
            data: formdata,
            processData: false,
            contentType: false,
            success: function(res) {

            },       
            error: function(res) {

             }       
             });
            }
        });

PHP

for($i=0; $i<count($_FILES['file']['name']); $i++){
    $target_path = "uploads/";
    $ext = explode('.', basename( $_FILES['file']['name'][$i]));
    $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext)-1]; 

    if(move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {
        echo "The file has been uploaded successfully <br />";
    } else{
        echo "There was an error uploading the file, please try again! <br />";
    }
}

/** 
    Edit: $target_path variable need to be reinitialized and should 
    be inside for loop to avoid appending previous file name to new one. 
*/

Please use the script above script for ajax upload. It will work

I am late for this but i want put some more solution relevant to this.

 @GetMapping
public ResponseEntity<List<JSONObject>> getRole() {
    return ResponseEntity.ok(service.getRole());
}

use the following

It will return a true or false

theObject instanceof Object

I was searching how to do something similar in WPF and I got this solution:

<ItemsControl ItemsSource="{Binding MyItems,Mode=OneWay}">
<ItemsControl.ItemsPanel>
    <ItemsPanelTemplate>
        <StackPanel Orientation="Vertical" />
    </ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
    <DataTemplate>
        <RadioButton 
            Content="{Binding}" 
            Command="{Binding Path=DataContext.CustomCommand, 
                        RelativeSource={RelativeSource Mode=FindAncestor,      
                        AncestorType={x:Type ItemsControl}} }"
            CommandParameter="{Binding}" />
    </DataTemplate>
</ItemsControl.ItemTemplate>

I hope this works for somebody else. I have a data context which is set automatically to the ItemsControls, and this data context has two properties: MyItems -which is a collection-, and one command 'CustomCommand'. Because of the ItemTemplate is using a DataTemplate, the DataContext of upper levels is not directly accessible. Then the workaround to get the DC of the parent is use a relative path and filter by ItemsControl type.

for bootstrap 4 documentation

  <div class="row justify-content-end">
    <div class="col-4">

    <div class="col-4">

time difference between now and 10 minutes later using momentjs

let start_time = moment().format('YYYY-MM-DD HH:mm:ss');
let next_time = moment().add(10, 'm').format('YYYY-MM-DD HH:mm:ss');

let diff_milliseconds = Date.parse(next_time) - Date.parse(star_time);
let diff_seconds = diff_milliseconds * 1000;

From the documentation I found this

JObject o = new JObject(
   new JProperty("Name", "John Smith"),
   new JProperty("BirthDate", new DateTime(1983, 3, 20))
);

JsonSerializer serializer = new JsonSerializer();
Person p = (Person)serializer.Deserialize(new JTokenReader(o), typeof(Person));

Console.WriteLine(p.Name);

The class definition for Person should be compatible to the following:

class Person {
    public string Name { get; internal set; }
    public DateTime BirthDate { get; internal set; }
}

Edit

If you are using a recent version of JSON.net and don't need custom serialization, please see TienDo's answer above (or below if you upvote me :P ), which is more concise.

Understanding that regex is not always the best solution, I'd probably use one here:

>>> import re
>>> s = "ababdfegtduab"
>>> [m.start() for m in re.finditer(r"ab",s)]
[0, 2, 11]
>>> [m.start() for m in re.finditer(r"ab",s)][2] #index 2 is third occurrence 
11

work with you apply runat="server" in your div section...

<div runat="server" id="hideid">

On your button click event:

 protected void btnSubmit_Click(object sender, EventArgs e)
    {
      hideid.Visible = false;
    }

In HTML5, there is no correct value, all the major browsers do not really care what the attribute is, they are just checking if the attribute exists so the element is disabled.

Here is my version: "Send Email In C # Using Gmail".

using System;
using System.Net;
using System.Net.Mail;

namespace SendMailViaGmail
{
   class Program
   {
   static void Main(string[] args)
   {

      //Specify senders gmail address
      string SendersAddress = "[email protected]";
      //Specify The Address You want to sent Email To(can be any valid email address)
      string ReceiversAddress = "[email protected]";
      //Specify The password of gmial account u are using to sent mail(pw of [email protected])
      const string SendersPassword = "Password";
      //Write the subject of ur mail
      const string subject = "Testing";
      //Write the contents of your mail
      const string body = "Hi This Is my Mail From Gmail";

      try
      {
        //we will use Smtp client which allows us to send email using SMTP Protocol
        //i have specified the properties of SmtpClient smtp within{}
        //gmails smtp server name is smtp.gmail.com and port number is 587
        SmtpClient smtp = new SmtpClient
        {
           Host = "smtp.gmail.com",
           Port = 587,
           EnableSsl = true,
           DeliveryMethod = SmtpDeliveryMethod.Network,
           Credentials    = new NetworkCredential(SendersAddress, SendersPassword),
           Timeout = 3000
        };

        //MailMessage represents a mail message
        //it is 4 parameters(From,TO,subject,body)

        MailMessage message = new MailMessage(SendersAddress, ReceiversAddress, subject, body);
        /*WE use smtp sever we specified above to send the message(MailMessage message)*/

        smtp.Send(message);
        Console.WriteLine("Message Sent Successfully");
        Console.ReadKey();
     }

     catch (Exception ex)
     {
        Console.WriteLine(ex.Message);
        Console.ReadKey();
     }
    }
   }
 }

If you want them to be displayed side by side, why is sideContent the child of mainContent? make them siblings then use:

float:left; display:inline; width: 49%;

on both of them.

#mainContent, #sideContent {float:left; display:inline; width: 49%;}

If you're on windows and using apache, maybe via WAMP or the Drupal stack installer, you can additionally download the git for windows package, which includes many useful linux command line tools, one of which is openssl.

The following command creates the self signed certificate and key needed for apache and works fine in windows:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privatekey.key -out certificate.crt

I happened to run into this problem because of missing SELinux permissions. By default, SELinux only allowed apache/httpd to bind to the following ports:

80, 81, 443, 488, 8008, 8009, 8443, 9000

So binding to my httpd.conf-configured Listen 88 HTTP port and config.d/ssl.conf-configured Listen 8445 TLS/SSL port would fail with that default SELinux configuration.

To fix my problem, I had to add ports 88 and 8445 to my system's SELinux configuration:

1. Install semanage tools: sudo yum -y install policycoreutils-python
2. Allow port 88 for httpd: sudo semanage port -a -t http_port_t -p tcp 88
3. Allow port 8445 for httpd: sudo semanage port -a -t http_port_t -p tcp 8445

OK guys, this is a small solution, but it works fine.

suppose the following code:

<div id='the_div_holder' style='height: 400px; overflow-y: scroll'>
  <div class='post'>1st post</div>
  <div class='post'>2nd post</div>
  <div class='post'>3rd post</div>
</div>

you want when a new post is added to 'the_div_holder' then it scrolls its inner content (the div's .post) to the last one like a chat. So, do the following whenever a new .post is added to the main div holder:

var scroll = function(div) {
    var totalHeight = 0;
    div.find('.post').each(function(){
       totalHeight += $(this).outerHeight();
    });
    div.scrollTop(totalHeight);
  }
  // call it:
  scroll($('#the_div_holder'));

In simple terms

• Coarse-grained - larger components than fine-grained, large subcomponents. Simply wraps one or more fine-grained services together into a more coarse­-grained operation.
• Fine-grained - smaller components of which the larger ones are composed, lower­level service

It is better to have more coarse-grained service operations, which are composed by fine-grained operations

A disabled element is, (self-explaining) disabled and thereby logically not editable, so:

set the disabled attribute [...] changes the editable attribute too

Is an intended and well-defined behaviour.

The real problem here seems to be you're trying to set disabled to false via setAttribute() which doesn't do what you're expecting. an element is disabled if the disabled-attribute is set, independent of it's value (so, disabled="true", disabled="disabled" and disabled="false" all do the same: the element gets disabled). you should instead remove the complete attribute:

element.removeAttribute("disabled");

or set that property directly:

element.disabled = false;

Use the below code in android.support.v4

FragmentTransaction ft1 = getFragmentManager().beginTransaction();
WebViewFragment w1 = new WebViewFragment();
w1.init(linkData.getLink());
ft1.addToBackStack(linkData.getName());
ft1.replace(R.id.listFragment, w1);
ft1.commit();

lista = list.sort(lista)

This should be

lista.sort()

The .sort() method is in-place, and returns None. If you want something not in-place, which returns a value, you could use

sorted_list = sorted(lista)

Aside #1: please don't call your lists list. That clobbers the builtin list type.

Aside #2: I'm not sure what this line is meant to do:

print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")

is it simply

print "value 1a + value 2 = value 3a value 4"

? In other words, I don't know why you're calling str on things which are already str.

Aside #3: sometimes you use print("something") (Python 3 syntax) and sometimes you use print "something" (Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..

The exception TypeError: 'NoneType' object is not subscriptable happens because the value of lista is actually None. You can reproduce TypeError that you get in your code if you try this at the Python command line:

None[0]

The reason that lista gets set to None is because the return value of list.sort() is None... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).

If you do not want to alter the original version you can use

other_list = sorted(lista)

Here is Whatangs answer if you want to get both sorted lists (python3).

X = ["a", "b", "c", "d", "e", "f", "g", "h", "i"]
Y = [ 0,   1,   1,    0,   1,   2,   2,   0,   1]

Zx, Zy = zip(*[(x, y) for x, y in sorted(zip(Y, X))])

print(list(Zx))  # [0, 0, 0, 1, 1, 1, 1, 2, 2]
print(list(Zy))  # ['a', 'd', 'h', 'b', 'c', 'e', 'i', 'f', 'g']

Just remember Zx and Zy are tuples. I am also wandering if there is a better way to do that.

Warning: If you run it with empty lists it crashes.

Because of the One Definition Rule (probably¹).

In C++, each non-inline object and function must have exactly one definition within the program. By #includeing the file in which foo(int) is defined (the CPP file), it is defined both in every file where foop.cpp is #included, and in foop.cpp itself (assuming foop.cpp is compiled).

You can make a function inline to override this behavior, but I'm not recommending that here. I have never seen a situation where it is necessary or even desirable to #include a CPP file.

There are situations where it is desireable to include a definition of something. This is specially true when you try to seperate the definition of a template from the declaration of it. In those cases, I name the file HPP rather than CPP to denote the difference.

¹: "(probably)" I say probably here because the actual code you've posted should compile without errors, but given the compiler error it seems likely that the code you posted isn't exactly the same as the code you're compiling.

The solution works for signed / negative numbers with leading zeros, for all Sql versions:

DECLARE
    @n money = -3,
    @length tinyint = 15,
    @decimals tinyint = 0

SELECT REPLICATE('-', CHARINDEX('-', @n, 1)) + REPLACE(REPLACE(str(@n, @length, @decimals), '-', ''), ' ', '0')

key is just a variable name.

for key in d:

will simply loop over the keys in the dictionary, rather than the keys and values. To loop over both key and value you can use the following:

For Python 3.x:

for key, value in d.items():

For Python 2.x:

for key, value in d.iteritems():

To test for yourself, change the word key to poop.

In Python 3.x, iteritems() was replaced with simply items(), which returns a set-like view backed by the dict, like iteritems() but even better. This is also available in 2.7 as viewitems().

The operation items() will work for both 2 and 3, but in 2 it will return a list of the dictionary's (key, value) pairs, which will not reflect changes to the dict that happen after the items() call. If you want the 2.x behavior in 3.x, you can call list(d.items()).

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

PURE JavaScript:

Creating the XMLHttpRequest:

function getHTTPObject() {
    /* Crea el objeto AJAX. Esta funcion es generica para cualquier utilidad de este tipo, 
       por lo que se puede copiar tal como esta aqui */
    var xmlhttp = false;
    /* No mas soporte para Internet Explorer
    try { // Creacion del objeto AJAX para navegadores no IE
        xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
    } catch(nIE) {
        try { // Creacion del objet AJAX para IE
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        } catch(IE) {
            if (!xmlhttp && typeof XMLHttpRequest!='undefined') 
                xmlhttp = new XMLHttpRequest();
        }
    }
    */
    xmlhttp = new XMLHttpRequest();
    return xmlhttp; 
}

JavaScript function to Send the info via POST:

function sendInfo() {
    var URL = "somepage.html"; //depends on you
    var Params = encodeURI("var1="+val1+"var2="+val2+"var3="+val3);
    console.log(Params);
    var ajax = getHTTPObject();     
    ajax.open("POST", URL, true); //True:Sync - False:ASync
    ajax.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
    ajax.setRequestHeader("Content-length", Params.length);
    ajax.setRequestHeader("Connection", "close");
    ajax.onreadystatechange = function() { 
        if (ajax.readyState == 4 && ajax.status == 200) {
            alert(ajax.responseText);
        } 
    }
    ajax.send(Params);
}

I have a similar solution to the above and it works for opening, saving, file selecting. I paste it into its own module and use in all the Access DB's I create. As the code states it requires Microsoft Office 14.0 Object Library. Just another option I suppose:

Public Function Select_File(InitPath, ActionType, FileType)
    ' Requires reference to Microsoft Office 14.0 Object Library.

    Dim fDialog As Office.FileDialog
    Dim varFile As Variant


    If ActionType = "FilePicker" Then
        Set fDialog = Application.FileDialog(msoFileDialogFilePicker)
        ' Set up the File Dialog.
    End If
    If ActionType = "SaveAs" Then
        Set fDialog = Application.FileDialog(msoFileDialogSaveAs)
    End If
    If ActionType = "Open" Then
        Set fDialog = Application.FileDialog(msoFileDialogOpen)
    End If
    With fDialog
        .AllowMultiSelect = False
        ' Disallow user to make multiple selections in dialog box
        .Title = "Please specify the file to save/open..."
        ' Set the title of the dialog box.
        If ActionType <> "SaveAs" Then
            .Filters.Clear
            ' Clear out the current filters, and add our own.
            .Filters.Add FileType, "*." & FileType
        End If
        .InitialFileName = InitPath
        ' Show the dialog box. If the .Show method returns True, the
        ' user picked a file. If the .Show method returns
        ' False, the user clicked Cancel.
        If .Show = True Then
        'Loop through each file selected and add it to our list box.
            For Each varFile In .SelectedItems
                'return the subroutine value as the file path & name selected
                Select_File = varFile
            Next
        End If
    End With
End Function

The error message means that you need to invoke volteado and siprimo on an instance of the Program class. E.g.:

...
Program p = new Program();
long av = p.volteado(a); // av is "a" but swapped

if (p.siprimo(a) == false && p.siprimo(av) == false)
...

They cannot be invoked directly from the Main method because Main is static while volteado and siprimo are not.

The easiest way to fix this is to make the volteado and siprimo methods static:

private static bool siprimo(long a)
{
    ...
}

private static bool volteado(long a)
{
   ...
}

There is not really any other way in JavaScript to concatenate strings.
You could theoretically use .concat(), but that's way slower than just +

Libraries are more often than not slower than native JavaScript, especially on basic operations like string concatenation, or numerical operations.

Simply put: + is the fastest.

Here is the answer from @mvanle, converted to Scala: scala> val Array(javaVerPrefix, javaVerMajor, javaVerMinor, _, _) = System.getProperty("java.runtime.version").split("\\.|_|-b") javaVerPrefix: String = 1 javaVerMajor: String = 8 javaVerMinor: String = 0

Update:

This is not the best answer anymore, please follow gregers' advice.

Old answer:

You can now use Safari for remote debugging. But it requires iOS 6.

Here is a quick translation of http://html5-mobile.de/blog/ios6-remote-debugging-web-inspector

1. Connect your iDevice via USB with your Mac
2. Open Safari on your Mac and activate the dev tools
3. On your iDevice: go to settings > safari > advanced and activate the web inspector
4. Go to any website with your iDevice
5. On your Mac: Open the developer menu and chose the site from your iDevice (its at the top Safari Menu)

As pointed out by Simons answer one need to turn off private browsing to make remote debugging work.

Settings > Safari > Private Browsing > OFF

I am Fully agree With BugFinder.

In simple Words, just put ip address 192.168.1.56 in your browser running on 192.168.1.2!

if it does not work then there are following possible reasons for that :

1. Network Connectivity Issue :

   • First of all Check your network Connectivity using ping 192.168.1.56 command in command prompt/terminal on 192.168.1.2 computer.

2. Firewall Problem : Your windows firewall setting do not have allowing rule for XAMPP(apache). (Most probable problem)

   • (solution) go to advanced firewall settings and add inbound and outbound rules for Apache executable file.

3. Apache Configuration problem. : Your apache is configured to listen only local requests.

   • (Solution) you can it by opening httpd.conf file and replace Listen 127.0.0.1:80 to Listen 80 or *Listen :80

4. Port Conflict with other Servers(IIS etc.)

   • (Solution) Turn off apache server and then open local host in browser. if any response is obtained then turnoff that server then start Apache.

if all above does not work then probably there is some configuration problem on your apache server.try to find it out otherwise just reinstall it and transfer all php files(htdocs) to new installation of XAMPP/WAMP.

For people who don't want to use Bouncy, and are trying some of the code included in other answers, I've found that the code works MOST of the time, but trips up on some RSA private strings, such as the one I've included below. By looking at the bouncy code, I tweaked the code provided by wprl to

    RSAparams.D = ConvertRSAParametersField(D, MODULUS.Length);
    RSAparams.DP = ConvertRSAParametersField(DP, P.Length);
    RSAparams.DQ = ConvertRSAParametersField(DQ, Q.Length);
    RSAparams.InverseQ = ConvertRSAParametersField(IQ, Q.Length);

    private static byte[] ConvertRSAParametersField(byte[] bs, int size)
    {
        if (bs.Length == size)
            return bs;

        if (bs.Length > size)
            throw new ArgumentException("Specified size too small", "size");

        byte[] padded = new byte[size];
        Array.Copy(bs, 0, padded, size - bs.Length, bs.Length);
        return padded;
    }

an even simpler solution is:

df = df.reindex(columns = header_list)                

where "header_list" is a list of the headers you want to appear.

any header included in the list that is not found already in the dataframe will be added with blank cells below.

so if

header_list = ['a','b','c', 'd']

then c and d will be added as columns with blank cells

Sometimes it doesn't get login with username = root and password, then you can change the default settings or the reset settings.

Open config.inc.php file in the phpmyadmin folder

Instead of

$cfg['Servers'][$i]['AllowNoPassword'] = false;

change it to:

$cfg['Servers'][$i]['AllowNoPassword'] = true;

Do not specify any password and put the user name as it was before, which means root.

E.g.

$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';

This worked for me after i had edited my config.inc.php file.

I had to include "PROJECT_NAME/osdep.h" and that includes the os specific configurations.

I would look in other files using the types you are interested in and find where/how they are defined (by looking at includes).

The trick is to intercept the form post and change the check boxes to hidden input fields.

Example: Plain Submit

$('form').on("submit", function (e) {
    //find the checkboxes
    var $checkboxes = $(this).find('input[type=checkbox]');

    //loop through the checkboxes and change to hidden fields
    $checkboxes.each(function() {
        if ($(this)[0].checked) {
            $(this).attr('type', 'hidden');
            $(this).val(1);
        } else {
            $(this).attr('type', 'hidden');
            $(this).val(0);
        }
    });
});

Example: AJAX

You need to jump through a few more hoops if you are posting the form via ajax to not update the UI.

$('form').on("submit", function (e) {
    e.preventDefault();

    //clone the form, we don't want this to impact the ui
    var $form = $('form').clone();

    //find the checkboxes
    var $checkboxes = $form.find('input[type=checkbox]');

    //loop through the checkboxes and change to hidden fields
    $checkboxes.each(function() {
        if ($(this)[0].checked) {
            $(this).attr('type', 'hidden');
            $(this).val(1);
        } else {
            $(this).attr('type', 'hidden');
            $(this).val(0);
        }
    });

    $.post("/your/path", $form.serialize());

try this code I think it is more optimal.

HeaderRow is used to repeat the header of the table for each new page automatically

        BaseFont bfTimes = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, false);
        iTextSharp.text.Font times = new iTextSharp.text.Font(bfTimes, 6, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);

        PdfPTable table = new PdfPTable(10) { HorizontalAlignment = Element.ALIGN_CENTER, WidthPercentage = 100, HeaderRows = 2 };
        table.SetWidths(new float[] { 2f, 6f, 6f, 3f, 5f, 8f, 5f, 5f, 5f, 5f });
        table.AddCell(new PdfPCell(new Phrase("SER.\nNO.", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("TYPE OF SHIPPING", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("ORDER NO.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("QTY.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DISCHARGE PPORT", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DESCRIPTION OF GOODS", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("LINE DOC. RECL DATE", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("CLEARANCE DATE", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("CUSTOM PERMIT NO.", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DISPATCH DATE", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("AWB/BL NO.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("COMPLEX NAME", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("G. W. Kgs.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DESTINATION", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("OWNER DOC. RECL DATE", times)) { GrayFill = 0.95f });

For positive numbers:

    q = x/y + (x % y != 0);

Interop with other languages founded on the DLR is #1 reason I can think of. You can't pass them a Dictionary<string, object> as it's not an IDynamicMetaObjectProvider. Another added benefit is that it implements INotifyPropertyChanged which means in the databinding world of WPF it also has added benefits beyond what Dictionary<K,V> can provide you.

This way you eliminate every special char outside of the alphabet:

def wordsToList(strn):
    L = strn.split()
    cleanL = []
    abc = 'abcdefghijklmnopqrstuvwxyz'
    ABC = abc.upper()
    letters = abc + ABC
    for e in L:
        word = ''
        for c in e:
            if c in letters:
                word += c
        if word != '':
            cleanL.append(word)
    return cleanL

s = 'She loves you, yea yea yea! '
L = wordsToList(s)
print(L)  # ['She', 'loves', 'you', 'yea', 'yea', 'yea']

I'm not sure if this is fast or optimal or even the right way to program.

When TOP is used with INSERT, UPDATE, MERGE, or DELETE, the referenced rows are not arranged in any order and the ORDER BY clause can not be directly specified in these statements. If you need to use TOP to insert, delete, or modify rows in a meaningful chronological order, you must use TOP together with an ORDER BY clause that is specified in a subselect statement.

TOP cannot be used in an UPDATE and DELETE statements on partitioned views.

TOP cannot be combined with OFFSET and FETCH in the same query expression (in the same query scope). For more information, see http://technet.microsoft.com/en-us/library/ms189463.aspx

Use +, the string concatenation operator:

ed = (EditText) findViewById (R.id.box);
int x = 10;
ed.setText(""+x);

or use String.valueOf(int):

ed.setText(String.valueOf(x));

or use Integer.toString(int):

ed.setText(Integer.toString(x));

Using String format will help but you must be care full with the locale. In germany float will be separates with in comma instead an point.

Using String.format("geo:%f,%f",5.1,2.1); on locale english the result will be "geo:5.1,2.1" but with locale german you will get "geo:5,1,2,1"

You should use the English locale to prevent this behavior.

String uri = String.format(Locale.ENGLISH, "geo:%f,%f", latitude, longitude);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
context.startActivity(intent);

To set an label to the geo point you can extend your geo uri by using:

!!! but be carefull with this the geo-uri is still under develoment http://tools.ietf.org/html/draft-mayrhofer-geo-uri-00

String uri = String.format(Locale.ENGLISH, "geo:%f,%f?z=%d&q=%f,%f (%s)", 
                           latitude, longitude, zoom, latitude, longitude, label);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
context.startActivity(intent);

If you could provide some reason as to why you need to replace the label with a div, that would certainly help...

Also, could you paste a sample that'd be helpful ( http://dpaste.com/ or http://pastebin.com/)

public static void DirectorySearch(string dir)
{
    try
    {
        foreach (string f in Directory.GetFiles(dir))
        {
            Console.WriteLine(Path.GetFileName(f));
        }
        foreach (string d in Directory.GetDirectories(dir))
        {
            Console.WriteLine(Path.GetFileName(d));
            DirectorySearch(d);
        }
    }
    catch (System.Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
}

Note: the function shows only names without relative paths.

Normally I use selenium, which is software for testing automation. You can control a browser through a webdriver, so you will not have problems with javascripts and it is usually not very detected if you use the full version. Headless browsers can be more identified.

For List<List<List<x>>> and so on, use

list.SelectMany(x => x.SelectMany(y => y)).ToList();

This has been posted in a comment, but it does deserves a separate reply in my opinion.

I'm not sure you can exclude packages explicitly with an <exclude-filter>, but I bet using a regex filter would effectively get you there:

 <context:component-scan base-package="com.example">
    <context:exclude-filter type="regex" expression="com\.example\.ignore\..*"/>
 </context:component-scan>

To make it annotation-based, you'd annotate each class you wanted excluded for integration tests with something like @com.example.annotation.ExcludedFromITests. Then the component-scan would look like:

 <context:component-scan base-package="com.example">
    <context:exclude-filter type="annotation" expression="com.example.annotation.ExcludedFromITests"/>
 </context:component-scan>

That's clearer because now you've documented in the source code itself that the class is not intended to be included in an application context for integration tests.

Install nmap,

sudo apt-get install nmap

then

nmap -sP 192.168.1.*

or more commonly

nmap -sn 192.168.1.0/24

will scan the entire .1 to .254 range

This does a simple ping scan in the entire subnet to see which hosts are online.

I've given this problem a lot of thought and have determined that the optimal solution should follow two rules.

1. For scalability, modify the array in place; no copying to a new array
2. For performance, each comparison should be made only once

With that in mind and given all of PHP's quirks, below is the solution I came up with. Unlike some of the other answers, it has the ability to remove elements based on whatever key(s) you want. The input array is expected to be numeric keys.

$count_array = count($input);
for ($i = 0; $i < $count_array; $i++) {
    if (isset($input[$i])) {
        for ($j = $i+1; $j < $count_array; $j++) {
            if (isset($input[$j])) {
                //this is where you do your comparison for dupes
                if ($input[$i]['checksum'] == $input[$j]['checksum']) {
                    unset($input[$j]);
                }
            }
        }
    }
}

The only drawback is that the keys are not in order when the iteration completes. This isn't a problem if you're subsequently using only foreach loops, but if you need to use a for loop, you can put $input = array_values($input); after the above to renumber the keys.

Sometimes you need to first update the apt repo list.

sudo apt-get update
sudo apt purge python2.7-minimal

Other than ERRORLEVEL, batch files have no error handling. You'd want to look at a more powerful scripting language. I've been moving code to PowerShell.

The ability to easily use .Net assemblies and methods was one of the major reasons I started with PowerShell. The improved error handling was another. The fact that Microsoft is now requiring all of its server programs (Exchange, SQL Server etc) to be PowerShell drivable was pure icing on the cake.

Right now, it looks like any time invested in learning and using PowerShell will be time well spent.

Use this to get the page scroll position.

var screenTop = $(document).scrollTop();

$('#content').css('top', screenTop);

I had the same problem and the solution was to encapsulate the json inside this function

jsonp(

Why do you get these ^M in your git diff?

In my case I was working on a project which was developed in Windows and I used OS X. When I changed some code, I saw ^M at the end of the lines I added in git diff. I think the ^M were showing up because they were different line endings than the rest of the file. Because the rest of the file was developed in Windows it used CR line endings, and in OS X it uses LF line endings.

Apparently, the Windows developer didn't use the option "Checkout Windows-style, commit Unix-style line endings" during the installation of Git.

So what should we do about this?

You can have the Windows users reinstall git and use the "Checkout Windows-style, commit Unix-style line endings" option. This is what I would prefer, because I see Windows as an exception in its line ending characters and Windows fixes its own issue this way.

If you go for this option, you should however fix the current files (because they're still using the CR line endings). I did this by following these steps:

1. Remove all files from the repository, but not from your filesystem.

   git rm --cached -r .
   

2. Add a .gitattributes file that enforces certain files to use a LF as line endings. Put this in the file:

   *.ext text eol=crlf
   

   Replace .ext with the file extensions you want to match.

3. Add all the files again.

   git add .
   

   This will show messages like this:

   warning: CRLF will be replaced by LF in <filename>.
   The file will have its original line endings in your working directory.
   

4. You could remove the .gitattributes file unless you have stubborn Windows users that don't want to use the "Checkout Windows-style, commit Unix-style line endings" option.

5. Commit and push it all.

6. Remove and checkout the applicable files on all the systems where they're used. On the Windows systems, make sure they now use the "Checkout Windows-style, commit Unix-style line endings" option. You should also do this on the system where you executed these tasks because when you added the files git said:

   The file will have its original line endings in your working directory.
   

   You can do something like this to remove the files:

   git ls | grep ".ext$" | xargs rm -f
   

   And then this to get them back with the correct line endings:

   git ls | grep ".ext$" | xargs git checkout
   

   Of course replacing .ext with the extension you want.

Now your project only uses LF characters for the line endings, and the nasty CR characters won't ever come back :).

The other option is to enforce windows style line endings. You can also use the .gitattributes file for this.

The wildcard library efficiently does both glob and regex filename matching:

</head>
<body>
<input type='file' onchange="readURL(this);" />
<img id="blah" src="#" alt="your image" />
</body>
</html>

JavaScript :

function readURL(input) {
  if (input.files && input.files[0]) {
    var reader = new FileReader();
    reader.onload = function (e) {
      $('#blah')
        .attr('src', e.target.result)
        .width(150)
        .height(200);
    };
    reader.readAsDataURL(input.files[0]);
  }
}

Like this:

public String getLocalIpAddress() {
    try {
        for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
            NetworkInterface intf = en.nextElement();
            for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
                InetAddress inetAddress = enumIpAddr.nextElement();
                if (!inetAddress.isLoopbackAddress()) {
                    return inetAddress.getHostAddress().toString();
                }
            }
        }
    } catch (SocketException ex) {
        Log.e(LOG_TAG, ex.toString());
    }
    return null;
}

Check the docs for more info: NetworkInterface.

There are three options:

Using jQuery (download from jQuery website) - jquery.com

var lines = $("#ptest").val().split("\n");
return lines.length;

Using Regex

var lines = str.split(/\r\n|\r|\n/);
return lines.length;

Or, a recreation of a for each loop

var length = 0;
for(var i = 0; i < str.length; ++i){
    if(str[i] == '\n') {
        length++;
    }
}
return length;

To exclude the lines that contain any of the strings in $arrayOfStringsNotInterestedIn, you should use:

(Get-Content $FileName) -notmatch [String]::Join('|',$arrayofStringsNotInterestedIn)

The code proposed by Chris only works if $arrayofStringsNotInterestedIn contains the full lines you want to exclude.

What's wrong with UNIX commands ? (given you're not working on Windows) :

ls | xargs cat | tee output.txt does the job ( you can call it from python with subprocess if you want)

var value_input = $("input[name*='xxxx']").val();

There are no conventions. There are some logical structure.

The only one thing that I can say: Never use camelCase file and directory names. Why? It works but on Mac and Windows there are no different between someAction and some action. I met this problem, and not once. I require'd a file like this:

var isHidden = require('./lib/isHidden');

But sadly I created a file with full of lowercase: lib/ishidden.js. It worked for me on mac. It worked fine on mac of my co-worker. Tests run without errors. After deploy we got a huge error:

Error: Cannot find module './lib/isHidden'

Oh yeah. It's a linux box. So camelCase directory structure could be dangerous. It's enough for a colleague who is developing on Windows or Mac.

So use underscore (_) or dash (-) separator if you need.

Controller :

public ActionResult Refresh(string ID)
    {
        DetailsViewModel vm = new DetailsViewModel();  // Model
        vm.productDetails = _product.GetproductDetails(ID); 
        /* "productDetails " is a property in "DetailsViewModel"
        "GetProductDetails" is a method in "Product" class
        "_product" is an interface of "Product" class */

        return PartialView("_Details", vm); // Details is a partial view
    }

In yore index page you should to have refresh link :

     <a href="#" id="refreshItem">Refresh</a>

This Script should be also in your index page:

<script type="text/javascript">

    $(function () {
    $('a[id=refreshItem]:last').click(function (e) {
        e.preventDefault();

        var url = MVC.Url.action('Refresh', 'MyController', { itemId: '@(Model.itemProp.itemId )' }); // Refresh is an Action in controller, MyController is a controller name

        $.ajax({
            type: 'GET',
            url: url,
            cache: false,
            success: function (grid) {
                $('#tabItemDetails').html(grid);
                clientBehaviors.applyPlugins($("#tabProductDetails")); // "tabProductDetails" is an id of div in your "Details partial view"
            }
        });
    });
});

Pattern p = Pattern.compile("(\\D+)(\\d+)(.*)");
Matcher m = p.matcher("this is your number:1234 thank you");
if (m.find()) {
    String someNumberStr = m.group(2);
    int someNumberInt = Integer.parseInt(someNumberStr);
}

SQL Server Management Studio provides an Import/Export wizard tool which have an option to automatically create tables.

You can access it by right clicking on the Database in Object Explorer and selecting Tasks->Import Data...

It's not possible to save content to the website using only client-side scripting such as JavaScript and jQuery, but by submitting the data in an AJAX POST request you could perform the other half very easily on the server-side.

However, I would not recommend having raw content such as scripts so easily writeable to your hosting as this could easily be exploited. If you want to learn more about AJAX POST requests, you can read the jQuery API page:

http://api.jquery.com/jQuery.post/

And here are some things you ought to be aware of if you still want to save raw script files on your hosting. You have to be very careful with security if you are handling files like this!

What's the first part of your Subversion repository URL?

• If your URL looks like: http://subversion/repos/, then you're probably going over Port 80.
• If your URL looks like: https://subversion/repos/, then you're probably going over Port 443.
• If your URL looks like: svn://subversion/, then you're probably going over Port 3690.
• If your URL looks like: svn+ssh://subversion/repos/, then you're probably going over Port 22.
• If your URL contains a port number like: http://subversion/repos:8080, then you're using that port.

I can't guarantee the first four since it's possible to reconfigure everything to use different ports, of if you go through a proxy of some sort.

If you're using a VPN, you may have to configure your VPN client to reroute these to their correct ports. A lot of places don't configure their correctly VPNs to do this type of proxying. It's either because they have some sort of anal-retentive IT person who's being overly security conscious, or because they simply don't know any better. Even worse, they'll give you a client where this stuff can't be reconfigured.

The only way around that is to log into a local machine over the VPN, and then do everything from that system.

Something shorter version based off Yermo Lamers' suggestion, this seems to work alright. Even with basic animations like fade in/out and even crazy batman newspaper rotate. http://jsfiddle.net/ketwaroo/mXy3E/

$('.modal').on('show.bs.modal', function(event) {
    var idx = $('.modal:visible').length;
    $(this).css('z-index', 1040 + (10 * idx));
});
$('.modal').on('shown.bs.modal', function(event) {
    var idx = ($('.modal:visible').length) -1; // raise backdrop after animation.
    $('.modal-backdrop').not('.stacked').css('z-index', 1039 + (10 * idx));
    $('.modal-backdrop').not('.stacked').addClass('stacked');
});

You could use .find("is"), it would return position of "is" in the string

or use .start() from re

>>> re.search("is", String).start()
2

Actually its match "is" from "This"

If you need to match per word, you should use \b before and after "is", \b is the word boundary.

>>> re.search(r"\bis\b", String).start()
5

I suspect that result1 has some characters at the end of it that you can't see in the debugger that follow the closing } character. What's the length of result1 versus result2? I'll note that result2 as you've quoted it has 169 characters.

GSON throws that particular error when there's extra characters after the end of the object that aren't whitespace, and it defines whitespace very narrowly (as the JSON spec does) - only \t, \n, \r, and space count as whitespace. In particular, note that trailing NUL (\0) characters do not count as whitespace and will cause this error.

If you can't easily figure out what's causing the extra characters at the end and eliminate them, another option is to tell GSON to parse in lenient mode:

Gson gson = new Gson();
JsonReader reader = new JsonReader(new StringReader(result1));
reader.setLenient(true);
Userinfo userinfo1 = gson.fromJson(reader, Userinfo.class);

You could also try this simpler regex:

 str = str.replaceAll("\\P{Alnum}", "");

This simple snippet of code does what you want

GestureDetector gestureDetector = new GestureDetector(getContext(), new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapConfirmed(MotionEvent e) {
                KeyboardUtil.hideKeyboard(getActivity());
                return true;
            }
        });
mScrollView.setOnTouchListener((v, e) -> gestureDetector.onTouchEvent(e));

Here's my solution. It exports window.currentMouseX and window.currentMouseY properties you can use anywhere. It uses the position of a hovered element (if any) initially and afterwards listens to mouse movements to set the correct values.

(function () {
    window.currentMouseX = 0;
    window.currentMouseY = 0;

    // Guess the initial mouse position approximately if possible:
    var hoveredElement = document.querySelectorAll(':hover');
    hoveredElement = hoveredElement[hoveredElement.length - 1]; // Get the most specific hovered element

    if (hoveredElement != null) {
        var rect = hoveredElement.getBoundingClientRect();
        // Set the values from hovered element's position
        window.currentMouseX = window.scrollX + rect.x;
        window.currentMouseY = window.scrollY + rect.y;
    }

    // Listen for mouse movements to set the correct values
    document.addEventListener('mousemove', function (e) {
        window.currentMouseX = e.pageX;
        window.currentMouseY = e.pageY;
    });
}())

Another way to get the selected tab index is:

var index = jQuery('#tabs').data('tabs').options.selected;

You can combine the columns without using macros. Type the following function in the formula bar:

=IF(ROW()<=COUNTA(A:A),INDEX(A:A,ROW()),IF(ROW()<=COUNTA(A:B),INDEX(B:B,ROW()-COUNTA(A:A)),IF(ROW()>COUNTA(A:C),"",INDEX(C:C,ROW()-COUNTA(A:B)))))

The statement uses 3 IF functions, because it needs to combine 3 columns:

• For column A, the function compares the row number of a cell with the total number of cells in A column that are not empty. If the result is true, the function returns the value of the cell from column A that is at row(). If the result is false, the function moves on to the next IF statement.
• For column B, the function compares the row number of a cell with the total number of cells in A:B range that are not empty. If the result is true, the function returns the value of the first cell that is not empty in column B. If false, the function moves on to the next IF statement.
• For column C, the function compares the row number of a cell with the total number of cells in A:C range that are not empty. If the result is true, the function returns a blank cell and doesn't do any more calculation. If false, the function returns the value of the first cell that is not empty in column C.

Try this

$('#searchbox input').bind('keypress', function(e) {
    if(e.keyCode==13){
        // Enter pressed... do anything here...
    }
});

let is interesting, because it allows us to do something like this:

(() => {
    var count = 0;

    for (let i = 0; i < 2; ++i) {
        for (let i = 0; i < 2; ++i) {
            for (let i = 0; i < 2; ++i) {
                console.log(count++);
            }
        }
    }
})();

Which results in counting [0, 7].

Whereas

(() => {
    var count = 0;

    for (var i = 0; i < 2; ++i) {
        for (var i = 0; i < 2; ++i) {
            for (var i = 0; i < 2; ++i) {
                console.log(count++);
            }
        }
    }
})();

Only counts [0, 1].

Range with step ES6, that works similar to python list(range(start, stop[, step])):

const range = (start, stop, step = 1) => {
  return [...Array(stop - start).keys()]
    .filter(i => !(i % Math.round(step)))
    .map(v => start + v)
}

Examples:

range(0, 8) // [0, 1, 2, 3, 4, 5, 6, 7]
range(4, 9) // [4, 5, 6, 7, 8]
range(4, 9, 2) // [4, 6, 8] 
range(4, 9, 3) // [4, 7]

You can use HTTP Toolkit to do exactly this.

It's especially useful if you need to do this quickly, with no code changes: you can open a terminal from HTTP Toolkit, run any Python code from there as normal, and you'll be able to see the full content of every HTTP/HTTPS request immediately.

There's a free version that can do everything you need, and it's 100% open source.

I'm the creator of HTTP Toolkit; I actually built it myself to solve the exact same problem for me a while back! I too was trying to debug a payment integration, but their SDK didn't work, I couldn't tell why, and I needed to know what was actually going on to properly fix it. It's very frustrating, but being able to see the raw traffic really helps.

[x+1 if x >= 45 else x+5 for x in l]

And for a reward, here is the comment, I wrote to remember this the first time I did this error:

Python's conditional expression is a if C else b and can't be used as:

[a for i in items if C else b]

The right form is:

[a if C else b for i in items]

Even though there is a valid form:

[a for i in items if C]

But that isn't the same as that is how you filter by C, but they can be combined:

[a if tC else b for i in items if fC]

If you are using SQL Server try this:

SELECT * FROM MyTable
WHERE MyDate < DATEADD(month, -2, GETDATE())

Based on your update it would be:

SELECT * FROM FB WHERE Dte <  DATEADD(month, -2, GETDATE())

I tried above answers and they didn't help in my case.

I solved it with this link help: http://vjscrazzy.blogspot.co.il/2016/02/failed-to-sync-gradle-project.html

step 1) file>Setttings>appearance and behaviour> system setttings>HTTP proxy> set No Proxy

step 2) build,execution and deployment> Build tools > gradle> now under project level settings > select local gradle distribution> gradle home = F:/Program Files/Android/Android Studio/gradle/gradle-2.4

After that, I did these changes(because it still wrote me some other errors)

Android Studio asked me:

1. Android Studio asked me to update my Gradle version (which he didn't before)

2. Enable - Tools> Android> Enable ADB integration.

Also, if your working in a team with repositories, it's important to check that the version of the Andorid Studio is the same.

Clone target repository same way like you cloning any other project:

git clone [email protected]:myuser/foo.git

Then install it in develop mode:

cd foo
pip install -e .

You can change anything you wan't and every code using foo package will use modified code.

There 2 benefits ot this solution:

1. You can install package in your home projects directory.
2. Package includes .git dir, so it's regular Git repository. You can push to your fork right away.

Send params from View to an other View, from Sender View to Receiver View use viewParam and includeViewParams=true

In Sender

1. Declare params to be sent. We can send String, Object,…

Sender.xhtml

<f:metadata>
      <f:viewParam name="ID" value="#{senderMB._strID}" />
</f:metadata>

2. We’re going send param ID, it will be included with “includeViewParams=true” in return String of click button event Click button fire senderMB.clickBtnDetail(dto) with dto from senderMB._arrData

Sender.xhtml

<p:dataTable rowIndexVar="index" id="dataTale"value="#{senderMB._arrData}" var="dto">
      <p:commandButton action="#{senderMB.clickBtnDetail(dto)}" value="??" 
      ajax="false"/>
</p:dataTable>

In senderMB.clickBtnDetail(dto) we assign _strID with argument we got from button event (dto), here this is Sender_DTO and assign to senderMB._strID

Sender_MB.java
    public String clickBtnDetail(sender_DTO sender_dto) {
        this._strID = sender_dto.getStrID();
        return "Receiver?faces-redirect=true&includeViewParams=true";
    }

The link when clicked will become http://localhost:8080/my_project/view/Receiver.xhtml?*ID=12345*

In Recever

1. Get viewParam Receiver.xhtml In Receiver we declare f:viewParam to get param from get request (receive), the name of param of receiver must be the same with sender (page)

Receiver.xhtml

<f:metadata><f:viewParam name="ID" value="#{receiver_MB._strID}"/></f:metadata>

It will get param ID from sender View and assign to receiver_MB._strID

2. Use viewParam In Receiver, we want to use this param in sql query before the page render, so that we use preRenderView event. We are not going to use constructor because constructor will be invoked before viewParam is received So that we add

Receiver.xhtml

<f:event listener="#{receiver_MB.preRenderView}" type="preRenderView" />

into f:metadata tag

Receiver.xhtml

<f:metadata>
<f:viewParam name="ID" value="#{receiver_MB._strID}" />
<f:event listener="#{receiver_MB.preRenderView}"
            type="preRenderView" />
</f:metadata>

Now we want to use this param in our read database method, it is available to use

Receiver_MB.java
public void preRenderView(ComponentSystemEvent event) throws Exception {
        if (FacesContext.getCurrentInstance().isPostback()) {
            return;
        }
        readFromDatabase();
    }
private void readFromDatabase() {
//use _strID to read and set property   
}

You can also use Bootstrap 4 flex classes

Like: .align-item-center and .justify-content-center

We can use these classes identically for all device view.

Like: .align-item-sm-center, .align-item-md-center, .justify-content-xl-center, .justify-content-lg-center, .justify-content-xs-center

.text-center class is used to align text in center.

Here's how you get the image size from the given URL in Python 3:

from PIL import Image
import urllib.request
from io import BytesIO

file = BytesIO(urllib.request.urlopen('http://getwallpapers.com/wallpaper/full/b/8/d/32803.jpg').read())
im = Image.open(file)
width, height = im.size

If you use ApplicationPoolIdentity for your application pool, you may have problem with specifying permission for that "virtual" user in registry editor (there is not such user in system).

So, use subinacl - command-line tool that enables set registry ACL's, or something like this.

I would recommend 422. It's not part of the main HTTP spec, but it is defined by a public standard (WebDAV) and it should be treated by browsers the same as any other 4xx status code.

From RFC 4918:

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

This is how I did it:

curl -v \
  --key ./admin-key.pem \
  --cert ./admin.pem \
  https://xxxx/api/v1/

If you have only one nav and you want to change it, you should change your variables.less: @navbar-height (somewhere near line 265, I can't recall how many lines I added to mine).

This is referenced by the mixin .navbar-vertical-align, which is used for example to position the "toggle" element, anything with .navbar-form, .navbar-btn, and .navbar-text.

If you have two navbars and want them to be different heights, Minder Saini's answer may work well enough, when qualified further by an , e.g., #topnav.navbar but should be tested across multiple device widths.

Within the dplyr world, try:

select(iris,contains("Sepal"))

See the Selection section in ?select for numerous other helpers like starts_with, ends_with, etc.

If you have less than 4 rows, you can use the head function ( head(data, 4) or head(data, n=4)) and it works like a charm. But, assume we have the following dataset with 15 rows

>data <- data <- read.csv("./data.csv", sep = ";", header=TRUE)

>data
 LungCap Age Height Smoke Gender Caesarean
1    6.475   6   62.1    no   male        no

3    9.550  16   69.7    no female       yes
4   11.125  14   71.0    no   male        no
5    4.800   5   56.9    no   male        no
6    6.225  11   58.7    no female        no
7    4.950   8   63.3    no   male       yes

9    8.875  15   70.5    no   male        no
10   6.800  11   59.2    no   male        no
11   6.900  12   59.3    no   male        no
12   6.100  13   59.4    no   male        no
13   6.110  14   59.5    no   male        no
14   6.120  15   59.6    no   male        no
15   6.130  16   59.7    no   male        no

Let's say, you want to select the first 10 rows. The easiest way to do it would be data[1:10, ].

> data[1:10,]
   LungCap Age Height Smoke Gender Caesarean
1    6.475   6   62.1    no   male        no

10   6.800  11   59.2    no   male        no

However, let's say you try to retrieve the first 19 rows and see the what happens - you will have missing values

Hope this help!

You can use attribute data-container="body" within popover

<i class="fa fa-info-circle" data-container="body" data-toggle="popover"
   data-placement="right" data-trigger="hover" title="Title"
   data-content="Your content"></i>

var map = {'myKey1':myObj1, 'mykey2':myObj2};
// You don't need any get function, just use
map['mykey1']

I ran through same problem, here is my solution. set the width of image same as android screen width and then scales the height

Bitmap myBitmap = BitmapFactory.decodeFile(image.getAbsolutePath());
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
Log.e("Screen width ", " "+width);
Log.e("Screen height ", " "+height);
Log.e("img width ", " "+myBitmap.getWidth());
Log.e("img height ", " "+myBitmap.getHeight());
float scaleHt =(float) width/myBitmap.getWidth();
Log.e("Scaled percent ", " "+scaleHt);
Bitmap scaled = Bitmap.createScaledBitmap(myBitmap, width, (int)(myBitmap.getWidth()*scaleHt), true);
myImage.setImageBitmap(scaled);

This is better for any size android screen. let me know if it works for you.

Or just...

var response = (function() {
    var a;
    // calculate a
    return a;
})();  

In this case, the response variable receives the return value of the function. The function executes immediately.

You can use this construct if you want to populate a variable with a value that needs to be calculated. Note that all calculation happens inside the anonymous function, so you don't pollute the global namespace.

Use this...

$('#cat_icon').click(function () {
    $('#categories').toggle("slow");
    //$('#cat_icon').hide();
});
$('.panel_title').click(function () {
    $('#categories').toggle("slow");
    //$('#cat_icon').show();
});

See this Example

Greetings.

Try this

i was facing lot of issues when i was trying other solution...... After lot of R&D now i got solution

1. create custom_spinner.xml in layout folder and paste this code

    <?xml version="1.0" encoding="utf-8"?>
   <RelativeLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:background="@color/colorGray">
   <TextView
   android:id="@+id/tv_spinnervalue"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:textColor="@color/colorWhite"
   android:gravity="center"
   android:layout_alignParentLeft="true"
   android:textSize="@dimen/_18dp"
   android:layout_marginTop="@dimen/_3dp"/>
   <ImageView
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_alignParentRight="true"
   android:background="@drawable/men_icon"/>
   </RelativeLayout>
   

2. in your activity

   Spinner spinner =(Spinner)view.findViewById(R.id.sp_colorpalates);
   String[] years = {"1996","1997","1998","1998"};
   spinner.setAdapter(new SpinnerAdapter(this, R.layout.custom_spinner, years));
   

3. create a new class of adapter

   public class SpinnerAdapter extends ArrayAdapter<String> {
   private String[] objects;
   
   public SpinnerAdapter(Context context, int textViewResourceId, String[] objects) {
       super(context, textViewResourceId, objects);
       this.objects=objects;
   }
   
   @Override
   public View getDropDownView(int position, View convertView, @NonNull ViewGroup parent) {
       return getCustomView(position, convertView, parent);
   }
   
   @NonNull
   @Override
   public View getView(int position, View convertView, @NonNull ViewGroup parent) {
       return getCustomView(position, convertView, parent);
   }
   
   private View getCustomView(final int position, View convertView, ViewGroup parent) {
       View row = LayoutInflater.from(parent.getContext()).inflate(R.layout.custom_spinner, parent, false);
       final TextView label=(TextView)row.findViewById(R.id.tv_spinnervalue);
       label.setText(objects[position]);
       return row;
   }
   }
   

In new version of jquery, could done it via following steps:

• get param array via serializeArray()
• call push() or similar methods to add additional params to the array,
• call $.param(arr) to get serialized string, which could be used as jquery ajax's data param.

Example code:

var paramArr = $("#loginForm").serializeArray();
paramArr.push( {name:'size', value:7} );
$.post("rest/account/login", $.param(paramArr), function(result) {
    // ...
}

Try the Join-Path cmdlet:

Get-ChildItem c:\code\*\bin\* -Filter *.dll | Foreach-Object {
    Join-Path -Path  $_.DirectoryName -ChildPath "$buildconfig\$($_.Name)" 
}

You can name cells. This is done by clicking the Name Box (that thing next to the formula bar which says "A1" for example) and typing a name, such as, "myvar". Now you can use that name instead of the cell reference:

= myvar*25

To avoid any ambiguity, use the utilities methods from SwingUtilities :

SwingUtilities.isLeftMouseButton(MouseEvent anEvent) SwingUtilities.isRightMouseButton(MouseEvent anEvent) SwingUtilities.isMiddleMouseButton(MouseEvent anEvent)

Check in build.gradle in app you have good compile link .I have mistake with this line compile 'com.android.support:support-annotations:x.x.x' delete and work.

function wait(time)
    local duration = os.time() + time
    while os.time() < duration do end
end

This is probably one of the easiest ways to add a wait/sleep function to your script

I feel that the overall answer does not handle if the dates 'wrap' around a year. This would be useful in understanding proximity to a date being accurate by day of year. In order to do these row operations, I did the following. (I had this used in a business setting in renewing customer subscriptions).

def get_date_difference(row, x, y):
    try:
        # Calcuating the smallest date difference between the start and the close date
        # There's some tricky logic in here to calculate for determining date difference
        # the other way around (Dec -> Jan is 1 month rather than 11)

        sub_start_date = int(row[x].strftime('%j')) # day of year (1-366)
        close_date = int(row[y].strftime('%j')) # day of year (1-366)

        later_date_of_year = max(sub_start_date, close_date) 
        earlier_date_of_year = min(sub_start_date, close_date)
        days_diff = later_date_of_year - earlier_date_of_year

# Calculates the difference going across the next year (December -> Jan)
        days_diff_reversed = (365 - later_date_of_year) + earlier_date_of_year
        return min(days_diff, days_diff_reversed)

    except ValueError:
        return None

Then the function could be:

dfAC_Renew['date_difference'] = dfAC_Renew.apply(get_date_difference, x = 'customer_since_date', y = 'renewal_date', axis = 1)

Here a solution without Apache Commons Codec's Base64:

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;

public class AdvancedEncryptionStandard
{
    private byte[] key;

    private static final String ALGORITHM = "AES";

    public AdvancedEncryptionStandard(byte[] key)
    {
        this.key = key;
    }

    /**
     * Encrypts the given plain text
     *
     * @param plainText The plain text to encrypt
     */
    public byte[] encrypt(byte[] plainText) throws Exception
    {
        SecretKeySpec secretKey = new SecretKeySpec(key, ALGORITHM);
        Cipher cipher = Cipher.getInstance(ALGORITHM);
        cipher.init(Cipher.ENCRYPT_MODE, secretKey);

        return cipher.doFinal(plainText);
    }

    /**
     * Decrypts the given byte array
     *
     * @param cipherText The data to decrypt
     */
    public byte[] decrypt(byte[] cipherText) throws Exception
    {
        SecretKeySpec secretKey = new SecretKeySpec(key, ALGORITHM);
        Cipher cipher = Cipher.getInstance(ALGORITHM);
        cipher.init(Cipher.DECRYPT_MODE, secretKey);

        return cipher.doFinal(cipherText);
    }
}

Usage example:

byte[] encryptionKey = "MZygpewJsCpRrfOr".getBytes(StandardCharsets.UTF_8);
byte[] plainText = "Hello world!".getBytes(StandardCharsets.UTF_8);
AdvancedEncryptionStandard advancedEncryptionStandard = new AdvancedEncryptionStandard(
        encryptionKey);
byte[] cipherText = advancedEncryptionStandard.encrypt(plainText);
byte[] decryptedCipherText = advancedEncryptionStandard.decrypt(cipherText);

System.out.println(new String(plainText));
System.out.println(new String(cipherText));
System.out.println(new String(decryptedCipherText));

Prints:

Hello world!
?;??LA+??b*
Hello world!

We can also use regular expression (/^([\w.-]+)@([\w-]+)((.(\w){2,3})+)$/i) to validate email address format is correct or not.

var emailRegex = new RegExp(/^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$/i);
 var valid = emailRegex.test(emailAddress);
  if (!valid) {
    alert("Invalid e-mail address");
    return false;
  } else
    return true;

For brevity, we can understand these two APIs like below:

1. X.class.isAssignableFrom(Y.class)

If X and Y are the same class, or X is Y's super class or super interface, return true, otherwise, false.

2. X.class.isInstance(y)

Say y is an instance of class Y, if X and Y are the same class, or X is Y's super class or super interface, return true, otherwise, false.

You can use the exit keyword. Here is an example from one of my batch files:

start myProgram.exe param1
exit

[ -z "${DEPLOY_ENV}" ] checks whether DEPLOY_ENV has length equal to zero. So you could run:

if [[ -z "${DEPLOY_ENV}" ]]; then
  MY_SCRIPT_VARIABLE="Some default value because DEPLOY_ENV is undefined"
else
  MY_SCRIPT_VARIABLE="${DEPLOY_ENV}"
fi

# or using a short-hand version

[[ -z "${DEPLOY_ENV}" ]] && MyVar='default' || MyVar="${DEPLOY_ENV}"

# or even shorter use

MyVar="${DEPLOY_ENV:-default_value}"

I also noticed that you can provide a group of coroutines in wait() by simply specifying the list:

result=loop.run_until_complete(asyncio.wait([
        say('first hello', 2),
        say('second hello', 1),
        say('third hello', 4)
    ]))

Whereas grouping in gather() is done by just specifying multiple coroutines:

result=loop.run_until_complete(asyncio.gather(
        say('first hello', 2),
        say('second hello', 1),
        say('third hello', 4)
    ))

by using property css:

background-size: cover;

You might try

rm -rvf /usr/local/go/

then remove any mention of go in e.g. your ~/.bashrc; then you need at least to logout and login.

However, be careful when doing that. You might break your system badly if something is wrong.

^{PS. I am assuming a Linux or POSIX system.}

If you have LineageOS 7.1.2 (and have root), try this solution from XDA.

After having tried all the solutions proposed here, none of which worked for my Nexus 4 (mako), I found one on XDA that solves the problem with the Android dialer (but not with other apps). Basically I downloaded a recompiled version of the Dialer.apk file, which simply ignores the proximity sensor and behaves in the same way as the stock dialer app does.

Rename /system/priv-app/Dialer/Dialer.apk to something, then place the downloaded file to that folder. After reboot, I had to install the new dialer manually (simply by clicking on it). So now the original app is replaced, and the calls should be handled by this new one.

[Downside: the new way to answer a call is by pulling down the status bar and clicking 'Answer' (or 'Dismiss'), the usual slider is missing. Also, you'll need to repeat this every time your Android updates to a newer version.]

We can do it nicely using Interceptors. You dont have to set options in all your services neither manage all your error responses, just define 2 interceptors (one to do something before sending the request to server and one to do something before sending the server's response to your service)

1. Define an AuthInterceptor class to do something before sending the request to the server. You can set the api token (retrieve it from localStorage, see step 4) and other options in this class.
2. Define an responseInterceptor class to do something before sending the server response to your service (httpClient). You can manage your server response, the most comon use is to check if the user's token is valid (if not clear token from localStorage and redirect to login).

3. In your app.module import HTTP_INTERCEPTORS from '@angular/common/http'. Then add to your providers the interceptors (AuthInterceptor and responseInterceptor). Doing this your app will consider the interceptors in all our httpClient calls.

4. At login http response (use http service), save the token at localStorage.

5. Then use httpClient for all your apirest services.

You can try like this:
yourArray.shift()

ThiefMaster's answer is 100% correct, although I came across a similar problem where I needed to fetch a property from a nested object (object within an object), so as an alternative to his answer, you can create a recursive solution that will allow you to define a nomenclature to grab any property, regardless of depth:

function fetchFromObject(obj, prop) {

    if(typeof obj === 'undefined') {
        return false;
    }

    var _index = prop.indexOf('.')
    if(_index > -1) {
        return fetchFromObject(obj[prop.substring(0, _index)], prop.substr(_index + 1));
    }

    return obj[prop];
}

Where your string reference to a given property ressembles property1.property2

I found a workaround to download latest version of ChromeDriver via WebDriverManager You could try something like,

WebDriver driver = null ;
boolean oldVersion = true;
String chromeVersion = "";
try {
    try{
        FileReader reader = new FileReader("chromeVersion.txt") ;
        BufferedReader br = new BufferedReader(reader) ;
        
        String line;
        
        while ((line = br.readLine()) != null){
            chromeVersion = line.trim();
        }
        reader.close();
    } catch (IOException e ) {}
    
    WebDriverManager.chromedriver().version(chromeVersion).setup();
    driver = new ChromeDriver() ;
} catch (Exception e) {
    oldVersion = false;
    String err = e.getMessage() ;
    chromeVersion = err.split("version is")[1].split("with binary path")[0].trim();
    try{
        FileWriter writer = new FileWriter("chromeVersion.txt", true) ;
        writer.write(chromeVersion) ;
        writer.close();
    } catch (IOException er ) {}
}

if (!oldVersion){
    WebDriverManager.chromedriver().version(chromeVersion).setup();
    driver = new ChromeDriver() ;
}

driver.get("https://www.google.com") ;

Add the image to Your project by clicking File -> "Add Files to ...".

Then choose the image in ImageView properties (Utilities -> Attributes Inspector).

If you're like me, and would rather not make this security hole system or user-wide, then you can add a config option to any git repos that need this by running this command in those repos. (note only works with git version >= 2.10, released 2016-09-04)

git config core.sshCommand 'ssh -oHostKeyAlgorithms=+ssh-dss'

This only works after the repo is setup however. If you're not comfortable adding a remote manually (and just want to clone) then you can run the clone like this:

GIT_SSH_COMMAND='ssh -oHostKeyAlgorithms=+ssh-dss' git clone ssh://user@host/path-to-repository

then run the first command to make it permanent.

If you don't have the latest, and still would like to keep the hole as local as possible I recommend putting

export GIT_SSH_COMMAND='ssh -oHostKeyAlgorithms=+ssh-dss'

in a file somewhere, say git_ssh_allow_dsa_keys.sh, and sourceing it when needed.

As of Android 2.1, Android only supports a single camera in its SDK. It is likely that this will be added in a future Android release.

Neevek's solution works better than Joel's on devices running 3.2 and above. There is a bug in Android that will cause java.lang.IllegalArgumentException: pointerIndex out of range if a gesture detector is used inside a scollview. To duplicate the issue, implement a custom scollview as Joel suggested and put a view pager inside. If you drag (don't lift you figure) to one direction (left/right) and then to the opposite, you will see the crash. Also in Joel's solution, if you drag the view pager by moving your finger diagonally, once your finger leave the view pager's content view area, the pager will spring back to its previous position. All these issues are more to do with Android's internal design or lack of it than Joel's implementation, which itself is a piece of smart and concise code.

I hadn't considered fillRect(), but the answers spurred me to benchmark it against putImage().

Putting 100,000 randomly coloured pixels in random locations, with Chrome 9.0.597.84 on an (old) MacBook Pro, takes less than 100ms with putImage(), but nearly 900ms using fillRect(). (Benchmark code at http://pastebin.com/4ijVKJcC).

If instead I choose a single colour outside of the loops and just plot that colour at random locations, putImage() takes 59ms vs 102ms for fillRect().

It seems that the overhead of generating and parsing a CSS colour specification in rgb(...) syntax is responsible for most of the difference.

Putting raw RGB values straight into an ImageData block on the other hand requires no string handling or parsing.

This problem may also come up if you include different versions of jQuery.

If testing on Windows, don't forget to open port 3306.

Still nothing good enough using native stuff. Here is what I ended up with:

public static string GetAbsoluteUrl(string url)
{
    //VALIDATE INPUT
    if (String.IsNullOrEmpty(url))
    {
        return String.Empty;
    }

    //VALIDATE INPUT FOR ALREADY ABSOLUTE URL
    if (url.StartsWith("http://", StringComparison.OrdinalIgnoreCase) || url.StartsWith("https://", StringComparison.OrdinalIgnoreCase))
    { 
        return url;
    }

    //GET CONTEXT OF CURRENT USER
    HttpContext context = HttpContext.Current;

    //RESOLVE PATH FOR APPLICATION BEFORE PROCESSING
    if (url.StartsWith("~/"))
    {
        url = (context.Handler as Page).ResolveUrl(url);
    }

    //BUILD AND RETURN ABSOLUTE URL
    string port = (context.Request.Url.Port != 80 && context.Request.Url.Port != 443) ? ":" + context.Request.Url.Port : String.Empty;
    return context.Request.Url.Scheme + Uri.SchemeDelimiter + context.Request.Url.Host + port + "/" + url.TrimStart('/');
}

You can completely handle it in the MySQL query:

SELECT SUM(column_name) FROM table_name;

Using PDO (mysql_query is deprecated)

$stmt = $handler->prepare('SELECT SUM(value) AS value_sum FROM codes');
$stmt->execute();

$row = $stmt->fetch(PDO::FETCH_ASSOC);
$sum = $row['value_sum'];

Or using mysqli:

$result = mysqli_query($conn, 'SELECT SUM(value) AS value_sum FROM codes'); 
$row = mysqli_fetch_assoc($result); 
$sum = $row['value_sum'];

I find it easiest (and most readable) to just copy the line and comment out the original version:

#Old version of ls:
#ls -l $([ ] && -F is turned off) -a /etc
ls -l -a /etc

var inp = $("#txt").val();
if(jQuery.trim(inp).length > 0)
{
   //do something
}

Removes white space before checking. If the user entered only spaces then this will still work.

My PHP is a little rusty, but I believe you're looking for indexed assignment. Simply use:

$catList[$row["datasource_id"]] = $row["title"];

In PHP arrays are actually maps, where the keys can be either integers or strings. Check out PHP: Arrays - Manual for more information.

Scala

Scala evolved out of a pure functional language known as Funnel and represents a clean-room implementation of almost all Java's syntax, differing only where a clear improvement could be made or where it would compromise the functional nature of the language. Such differences include singleton objects instead of static methods, and type inference.

Much of this was based on Martin Odersky's prior work with the Pizza language. The OO/FP integration goes far beyond mere closures and has led to the language being described as post-functional.

Despite this, it's the closest to Java in many ways. Mainly due to a combination of OO support and static typing, but also due to a explicit goal in the language design that it should integrate very tightly with Java.

Groovy

Groovy explicitly tackles two of Java's biggest criticisms by

• being dynamically typed, which removes a lot of boilerplate and
• adding closures to the language.

It's perhaps syntactically closest to Java, not offering some of the richer functional constructs that Clojure and Scala provide, but still offering a definite evolutionary improvement - especially for writing script-syle programs.

Groovy has the strongest commercial backing of the three languages, mostly via springsource.

Clojure

Clojure is a functional language in the LISP family, it's also dynamically typed.

Features such as STM support give it some of the best out-of-the-box concurrency support, whereas Scala requires a 3rd-party library such as Akka to duplicate this.

Syntactically, it's also the furthest of the three languages from typical Java code.

I also have to disclose that I'm most acquainted with Scala :)

Having a "table" in memory that needs lookups, sorting, and arbitrary aggregation really does call out for SQL. You said you tried SQLite, but did you realize that SQLite can use an in-memory-only database?

connection = sqlite3.connect(':memory:')

Then you can create/drop/query/update tables in memory with all the functionality of SQLite and no files left over when you're done. And as of Python 2.5, sqlite3 is in the standard library, so it's not really "overkill" IMO.

Here is a sample of how one might create and populate the database:

import csv
import sqlite3

db = sqlite3.connect(':memory:')

def init_db(cur):
    cur.execute('''CREATE TABLE foo (
        Row INTEGER,
        Name TEXT,
        Year INTEGER,
        Priority INTEGER)''')

def populate_db(cur, csv_fp):
    rdr = csv.reader(csv_fp)
    cur.executemany('''
        INSERT INTO foo (Row, Name, Year, Priority)
        VALUES (?,?,?,?)''', rdr)

cur = db.cursor()
init_db(cur)
populate_db(cur, open('my_csv_input_file.csv'))
db.commit()

If you'd really prefer not to use SQL, you should probably use a list of dictionaries:

lod = [ ] # "list of dicts"

def populate_lod(lod, csv_fp):
    rdr = csv.DictReader(csv_fp, ['Row', 'Name', 'Year', 'Priority'])
    lod.extend(rdr)

def query_lod(lod, filter=None, sort_keys=None):
    if filter is not None:
        lod = (r for r in lod if filter(r))
    if sort_keys is not None:
        lod = sorted(lod, key=lambda r:[r[k] for k in sort_keys])
    else:
        lod = list(lod)
    return lod

def lookup_lod(lod, **kw):
    for row in lod:
        for k,v in kw.iteritems():
            if row[k] != str(v): break
        else:
            return row
    return None

Testing then yields:

>>> lod = []
>>> populate_lod(lod, csv_fp)
>>> 
>>> pprint(lookup_lod(lod, Row=1))
{'Name': 'Cat', 'Priority': '1', 'Row': '1', 'Year': '1998'}
>>> pprint(lookup_lod(lod, Name='Aardvark'))
{'Name': 'Aardvark', 'Priority': '1', 'Row': '4', 'Year': '2000'}
>>> pprint(query_lod(lod, sort_keys=('Priority', 'Year')))
[{'Name': 'Cat', 'Priority': '1', 'Row': '1', 'Year': '1998'},
 {'Name': 'Dog', 'Priority': '1', 'Row': '3', 'Year': '1999'},
 {'Name': 'Aardvark', 'Priority': '1', 'Row': '4', 'Year': '2000'},
 {'Name': 'Wallaby', 'Priority': '1', 'Row': '5', 'Year': '2000'},
 {'Name': 'Fish', 'Priority': '2', 'Row': '2', 'Year': '1998'},
 {'Name': 'Zebra', 'Priority': '3', 'Row': '6', 'Year': '2001'}]
>>> pprint(query_lod(lod, sort_keys=('Year', 'Priority')))
[{'Name': 'Cat', 'Priority': '1', 'Row': '1', 'Year': '1998'},
 {'Name': 'Fish', 'Priority': '2', 'Row': '2', 'Year': '1998'},
 {'Name': 'Dog', 'Priority': '1', 'Row': '3', 'Year': '1999'},
 {'Name': 'Aardvark', 'Priority': '1', 'Row': '4', 'Year': '2000'},
 {'Name': 'Wallaby', 'Priority': '1', 'Row': '5', 'Year': '2000'},
 {'Name': 'Zebra', 'Priority': '3', 'Row': '6', 'Year': '2001'}]
>>> print len(query_lod(lod, lambda r:1997 <= int(r['Year']) <= 2002))
6
>>> print len(query_lod(lod, lambda r:int(r['Year'])==1998 and int(r['Priority']) > 2))
0

Personally I like the SQLite version better since it preserves your types better (without extra conversion code in Python) and easily grows to accommodate future requirements. But then again, I'm quite comfortable with SQL, so YMMV.

A simple way to convert arbitrary NSData to NSString is to base64 encode it.

NSString *base64EncodedKey = [keydata base64EncodedStringWithOptions: NSDataBase64Encoding64CharacterLineLength];

You can then store it into your database for reuse later. Just decode it back to NSData.

Put a single listener on the table. When it gets a click from an input with a button that has a name of "edit" and value "edit", change its value to "modify". Get rid of the input's id (they aren't used for anything here), or make them all unique.

<script type="text/javascript">

function handleClick(evt) {
  var node = evt.target || evt.srcElement;
  if (node.name == 'edit') {
    node.value = "Modify";
  }
}

</script>

<table id="table1" border="1" onclick="handleClick(event);">
    <thead>
      <tr>
          <th>Select
    </thead>
    <tbody>
       <tr> 
           <td>
               <form name="f1" action="#" >
                <input id="edit1" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f2" action="#" >
                <input id="edit2" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f3" action="#" >
                <input id="edit3" type="submit" name="edit" value="Edit">
               </form>

   </tbody>
</table>

In case of windows, one of the options you have is to uninstall current version of Node. Then, go to the node website and download the desired version and install this last one instead.

If you don't want to include any extra CSS you can just use the button color classes into the nav-link element, it will format the pill just the same as a regular button.

It's common for other components to be listening to the change event, or for custom event handlers to be attached that may have side effects. Select2 does not have a custom event (like select2:update) that can be triggered other than change. You can rely on jQuery's event namespacing to limit the scope to Select2 though by triggering the *change.select2 event.

$('#state').trigger('change.select2'); // Notify only Select2 of changes

If you want your container to have it's own virtual ethernet socket (with it's own MAC address), iptables, then use the Macvlan driver. This may be necessary to route traffic out to your/ISPs router.

You can simply use theatol()function:

#include <stdio.h>
#include <stdlib.h>

int main() 
{
    const char *c = "5";
    int d = atol(c);
    printf("%d\n", d);

}

You comment:

valeur is a vector equal to [ 0. 1. 2. 3.] I am interested in each single term. For the part below 0.6, then return "this works"....

If you are interested in each term, then write the code so it deals with each. For example.

for b in valeur<=0.6:
    if b:
        print ("this works")
    else:   
        print ("valeur is too high")

This will write 2 lines.

The error is produced by numpy code when you try to use it a context that expects a single, scalar, value. if b:... can only do one thing. It does not, by itself, iterate through the elements of b doing a different thing for each.

You could also cast that iteration as list comprehension, e.g.

['yes' if b else 'no' for b in np.array([True, False, True])]

you can use the new push/pop state functions in the history manipulation API.

jQuery is not the same as an array. If you want to append something at the end of a jQuery object, use:

$('#fruit').append(veggies);

or to append it to the end of a form value like in your example:

 $('#fruit').val($('#fruit').val()+veggies);

In your case, fruitvegbasket is a string that contains the current value of #fruit, not an array.

jQuery (jquery.com) allows for DOM manipulation, and the specific function you called val() returns the value attribute of an input element as a string. You can't push something onto a string.
