If you use yum search you can find the python dev package for your version of python.

For me I was using python 3.5. I ran the following

yum search python | grep devel

Which returned the following

I was then able to install the correct package for my version of python with the following cmd.

sudo yum install python35u-devel.x86_64

This works on centos for ubuntu or debian you would need to use apt-get

The ability to search commits has recently been added to GitHub.

To search for a hash, just enter at least the first 7 characters in the search box. Then on the results page, click the "Commits" tab to see matching commits (but only on the default branch, usually master), or the "Issues" tab to see pull requests containing the commit.

To be more explicit you can add the hash: prefix to the search, but it's not really necessary.

There is also a REST API (at the time of writing it is still in preview).

Non-VBA Solution:

You need to make an additional group of data for each color group that represent the Y values for that particular group. You can use these groups to make multiple data sets within your graph.

Here is an example using your data:

     A       B        C        D                    E                        F                            G
----------------------------------------------------------------------------------------------------------------------
1| COMPANY  XVALUE   YVALUE   GROUP                 Red                     Orange                       Green
2| Apple     45       35       red         =IF($D2="red",$C2,NA()) =IF($D2="orange",$C2,NA()) =IF($D2="green",$C2,NA())
3| Xerox     45       38       red         =IF($D3="red",$C3,NA()) =IF($D3="orange",$C3,NA()) =IF($D3="green",$C3,NA())
4| KMart     63       50       orange      =IF($D4="red",$C4,NA()) =IF($D4="orange",$C4,NA()) =IF($D4="green",$C4,NA())
5| Exxon     53       59       green       =IF($D5="red",$C5,NA()) =IF($D5="orange",$C5,NA()) =IF($D5="green",$C5,NA())

It should look like this afterwards:

     A       B        C        D          E           F          G
---------------------------------------------------------------------
1| COMPANY  XVALUE   YVALUE   GROUP       Red         Orange     Green
2| Apple     45       35       red         35         #N/A       #N/A    
3| Xerox     45       38       red         38         #N/A       #N/A
4| KMart     63       50       orange     #N/A         50        #N/A
5| Exxon     53       59       green      #N/a        #N/A        59

Now you can generate your graph using different data sets. Here is a picture showing just this example data:

You can change the series (X;Y) values to B:B ; E:E, B:B ; F:F, B:B ; G:G respectively, to make it so the graph is automatically updated when you add more data.

Share Files, Folders or Drives Between Host and Hyper-V Virtual Machine

Prerequisites

1. Ensure that Enhanced session mode settings are enabled on the Hyper-V host.

   Start Hyper-V Manager, and in the Actions section, select "Hyper-V Settings".

   

   Make sure that enhanced session mode is allowed in the Server section. Then, make sure that the enhanced session mode is available in the User section.

   

2. Enable Hyper-V Guest Services for your virtual machine

   Right-click on Virtual Machine > Settings. Select the Integration Services in the left-lower corner of the menu. Check Guest Service and click OK.

   

Steps to share devices with Hyper-v virtual machine:

1. Start a virtual machine and click Show Options in the pop-up windows.

   

   Or click "Edit Session Settings..." in the Actions panel on the right

   

   It may only appear when you're (able to get) connected to it. If it doesn't appear try Starting and then Connecting to the VM while paying close attention to the panel in the Hyper-V Manager.

2. View local resources. Then, select the "More..." menu.

   

3. From there, you can choose which devices to share. Removable drives are especially useful for file sharing.

   

4. Choose to "Save my settings for future connections to this virtual machine".

   

5. Click Connect. Drive sharing is now complete, and you will see the shared drive in this PC > Network Locations section of Windows Explorer after using the enhanced session mode to sigh to the VM. You should now be able to copy files from a physical machine and paste them into a virtual machine, and vice versa.

Mladen's basic idea worked (thanks), but needed a few changes to be robust, so I contributed them here.

The only place where this type of solution should be used is if you want to clone the object, but can't because it is a managed object. If you are lucky enough to have objects that all have 100% side-effect free setters for all fields, you should definitely use the BeanUtils option instead.

Here, I use lang3's utility methods to simplify the code, so if you paste it, you must first import Apache's lang3 library.

Copy code

static public <X extends Object> X copy(X object, String... skipFields) {
        Constructor constructorToUse = null;
        for (Constructor constructor : object.getClass().getConstructors()) {
            if (constructor.getParameterTypes().length == 0) {
                constructorToUse = constructor;
                constructorToUse.setAccessible(true);
                break;
            }
        }
        if (constructorToUse == null) {
            throw new IllegalStateException(object + " must have a zero arg constructor in order to be copied");
        }
        X copy;
        try {
            copy = (X) constructorToUse.newInstance();

            for (Field field : FieldUtils.getAllFields(object.getClass())) {
                if (Modifier.isStatic(field.getModifiers())) {
                    continue;
                }

                //Avoid the fields that you don't want to copy. Note, if you pass in "id", it will skip any field with "id" in it. So be careful.
                if (StringUtils.containsAny(field.getName(), skipFields)) {
                    continue;
                }

                field.setAccessible(true);

                Object valueToCopy = field.get(object);
                //TODO add here other special types of fields, like Maps, Lists, etc.
                field.set(copy, valueToCopy);

            }

        } catch (InstantiationException | IllegalAccessException | IllegalArgumentException
                | InvocationTargetException e) {
            throw new IllegalStateException("Could not copy " + object, e);
        }
        return copy;
}

They are just totally different. Consider this example of a volatile integer:

volatile int i = 0;
void incIBy5() {
    i += 5;
}

If two threads call the function concurrently, i might be 5 afterwards, since the compiled code will be somewhat similar to this (except you cannot synchronize on int):

void incIBy5() {
    int temp;
    synchronized(i) { temp = i }
    synchronized(i) { i = temp + 5 }
}

If a variable is volatile, every atomic access to it is synchronized, but it is not always obvious what actually qualifies as an atomic access. With an Atomic* object, it is guaranteed that every method is "atomic".

Thus, if you use an AtomicInteger and getAndAdd(int delta), you can be sure that the result will be 10. In the same way, if two threads both negate a boolean variable concurrently, with an AtomicBoolean you can be sure it has the original value afterwards, with a volatile boolean, you can't.

So whenever you have more than one thread modifying a field, you need to make it atomic or use explicit synchronization.

The purpose of volatile is a different one. Consider this example

volatile boolean stop = false;
void loop() {
    while (!stop) { ... }
}
void stop() { stop = true; }

If you have a thread running loop() and another thread calling stop(), you might run into an infinite loop if you omit volatile, since the first thread might cache the value of stop. Here, the volatile serves as a hint to the compiler to be a bit more careful with optimizations.

This answer will be robust enough to work for elements that aren't on the page, therefore failing gracefully (not throwing an exception) if the selector failed to find the element.

const nameSelector = '[data-automation="name-input"]';
const nameInputIsDisplayed = () => {
    return $$(nameSelector).count()
        .then(count => count !== 0)
}
it('should be displayed', () => {
    nameInputIsDisplayed().then(isDisplayed => {
        expect(isDisplayed).toBeTruthy()
    })
})

I found a fairly robust solution at https://gallery.technet.microsoft.com/scriptcenter/c0c57332-8624-48c0-b4c3-5b31fe641c58 , which I thought was worth pointing out. It searches columns of these types: varchar, char, nvarchar, nchar, text. It works great and supports specific table-searching as well as multiple search-terms.

The -regex find expression matches the whole name, including the relative path from the current directory. For find . this always starts with ./, then any directories.

Also, these are emacs regular expressions, which have other escaping rules than the usual egrep regular expressions.

If these are all directly in the current directory, then

find . -regex '\./[a-f0-9\-]\{36\}\.jpg'

should work. (I'm not really sure - I can't get the counted repetition to work here.) You can switch to egrep expressions by -regextype posix-egrep:

find . -regextype posix-egrep -regex '\./[a-f0-9\-]{36}\.jpg'

(Note that everything said here is for GNU find, I don't know anything about the BSD one which is also the default on Mac.)

Added some more logic to solution provided by @Andrew Burgess. Here is the full solution:

Created a action filter to get errors for ajax request:

public class ValidateAjaxAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            if (!filterContext.HttpContext.Request.IsAjaxRequest())
                return;

            var modelState = filterContext.Controller.ViewData.ModelState;
            if (!modelState.IsValid)
            {
                var errorModel =
                        from x in modelState.Keys
                        where modelState[x].Errors.Count > 0
                        select new
                        {
                            key = x,
                            errors = modelState[x].Errors.
                                                          Select(y => y.ErrorMessage).
                                                          ToArray()
                        };
                filterContext.Result = new JsonResult()
                {
                    Data = errorModel
                };
                filterContext.HttpContext.Response.StatusCode =
                                                      (int)HttpStatusCode.BadRequest;
            }
        }
    }

Added the filter to my controller method as:

[HttpPost]
// this line is important
[ValidateAjax]
public ActionResult AddUpdateData(MyModel model)
{
    return Json(new { status = (result == 1 ? true : false), message = message }, JsonRequestBehavior.AllowGet);
}

Added a common script for jquery validation:

function onAjaxFormError(data) {
    var form = this;
    var errorResponse = data.responseJSON;
    $.each(errorResponse, function (index, value) {
        // Element highlight
        var element = $(form).find('#' + value.key);
        element = element[0];
        highLightError(element, 'input-validation-error');

        // Error message
        var validationMessageElement = $('span[data-valmsg-for="' + value.key + '"]');
        validationMessageElement.removeClass('field-validation-valid');
        validationMessageElement.addClass('field-validation-error');
        validationMessageElement.text(value.errors[0]);
    });
}

$.validator.setDefaults({
            ignore: [],
            highlight: highLightError,
            unhighlight: unhighlightError
        });

var highLightError = function(element, errorClass) {
    element = $(element);
    element.addClass(errorClass);
}

var unhighLightError = function(element, errorClass) {
    element = $(element);
    element.removeClass(errorClass);
}

Finally added the error javascript method to my Ajax Begin form:

@model My.Model.MyModel
@using (Ajax.BeginForm("AddUpdateData", "Home", new AjaxOptions { HttpMethod = "POST", OnFailure="onAjaxFormError" }))
{
}

I found some elegant solution on MSDN

System.Console.Write('\uXXXX') //XXXX is hex Unicode for character

This simple program writes ? right on the screen.

using System;

public class Test
{
    public static void Main()
    {
        Console.Write('\u2103'); //? character code
    }
}

To check for the NULL data for column1 and consider your datatype of it is String, you could use below command :

select * from tbl_name where column1 is null or column1 <> '';

Solution from Google team

Starting from Android 5.0 that's easily achievable through the new Google Play In App updates mechanism. The requirements are to have Play Core library of version 1.5.0+ and use App Bundles idstribution instead of apks.

The library provides you 2 different ways to notify the users about the update:

1. Flexible, when users can continue using the app while it is being updated in the background.

2. Immediate - blocking screen that doesn't allow a user to enter the app until they update it.

There are next steps to implement it:

1. Check for update availability
2. Start an update
3. Get a callback for update status
4. Handle the update

All of these steps implementations are described in details on the official site: https://developer.android.com/guide/app-bundle/in-app-updates

It may be a little late, but you could use the helper function time() to get the current timestamp. I tried this function and it did the job, no need for classes :).

You can find this in the official documentation at https://laravel.com/docs/5.0/templates

int arr[5][4];

For the row subscript(4 raise to 2, include cmath to use pow):

sizeof(arr1)/pow(4,2)   

Column subscript:

sizeof(*arr1)/4

4 means 4 bytes, size of int.

Try this

In DJango 3.0 the default value of a BooleanField in model.py is set like this:

class model_name(models.Model):
example_name = models.BooleanField(default=False)

It is possible to do (in the deployed repository)

git fetch
git checkout origin/master -- path/to/file

The fetch will download all the recent changes, but it will not put it in your current checked out code (working area).

The checkout will update the working tree with the particular file from the downloaded changes (origin/master).

At least this works for me for those little small typo fixes, where it feels weird to create a branch etc just to change one word in a file.

I like the solution of Javier. I did not try it, but it sounds cool!

For reading through a arbitary large text and wanting to know it a string exists, replace it, you can use Flashtext, which is faster than Regex with very large files.

Edit:

From the developer page:

>>> from flashtext import KeywordProcessor
>>> keyword_processor = KeywordProcessor()
>>> # keyword_processor.add_keyword(<unclean name>, <standardised name>)
>>> keyword_processor.add_keyword('Big Apple', 'New York')
>>> keyword_processor.add_keyword('Bay Area')
>>> keywords_found = keyword_processor.extract_keywords('I love Big Apple and Bay Area.')
>>> keywords_found
>>> # ['New York', 'Bay Area']

Or when extracting the offset:

>>> from flashtext import KeywordProcessor
>>> keyword_processor = KeywordProcessor()
>>> keyword_processor.add_keyword('Big Apple', 'New York')
>>> keyword_processor.add_keyword('Bay Area')
>>> keywords_found = keyword_processor.extract_keywords('I love big Apple and Bay Area.', span_info=True)
>>> keywords_found
>>> # [('New York', 7, 16), ('Bay Area', 21, 29)]

You should add then function to instance. Promise will recognize it as a thenable object with Promise.resolve automatically

const asyncSymbol = Symbol();
class MyClass {
    constructor() {
        this.asyncData = null
    }
    then(resolve, reject) {
        return (this[asyncSymbol] = this[asyncSymbol] || new Promise((innerResolve, innerReject) => {
            this.asyncData = { a: 1 }
            setTimeout(() => innerResolve(this.asyncData), 3000)
        })).then(resolve, reject)
    }
}

async function wait() {
    const asyncData = await new MyClass();
    alert('run 3s later')
    alert(asyncData.a)
}

hostname also works just fine in Powershell

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

Can you include some code? I add style="display:none;" to my table rows all the time and it effectively hides the entire row.

You don't have to implement your own FIFO Queue, just look at the interface java.util.Queue and its implementations

First of all run installation as below:

npm install --save rxjs-compat@6

Now you need to import rxjs in service.ts:

import 'rxjs/Rx'; 

Voila! The problem has been fixed.

There are two contradicting recommendations by microsoft and many people use DbContexts in a completely divergent manner.

1. One recommendation is to "Dispose DbContexts as soon as posible" because having a DbContext Alive occupies valuable resources like db connections etc....
2. The other states that One DbContext per request is highly reccomended

Those contradict to each other because if your Request is doing a lot of unrelated to the Db stuff , then your DbContext is kept for no reason. Thus it is waste to keep your DbContext alive while your request is just waiting for random stuff to get done...

So many people who follow rule 1 have their DbContexts inside their "Repository pattern" and create a new Instance per Database Query so X*DbContext per Request

They just get their data and dispose the context ASAP. This is considered by MANY people an acceptable practice. While this has the benefits of occupying your db resources for the minimum time it clearly sacrifices all the UnitOfWork and Caching candy EF has to offer.

Keeping alive a single multipurpose instance of DbContext maximizes the benefits of Caching but since DbContext is not thread safe and each Web request runs on it's own thread, a DbContext per Request is the longest you can keep it.

So EF's team recommendation about using 1 Db Context per request it's clearly based on the fact that in a Web Application a UnitOfWork most likely is going to be within one request and that request has one thread. So one DbContext per request is like the ideal benefit of UnitOfWork and Caching.

But in many cases this is not true. I consider Logging a separate UnitOfWork thus having a new DbContext for Post-Request Logging in async threads is completely acceptable

So Finally it turns down that a DbContext's lifetime is restricted to these two parameters. UnitOfWork and Thread

What you can try to do is get the transformation Matrix from the animation before you stop it and inspect the Matrix contents to get the position values you are looking for.

Here are the api's you should look into

public boolean getTransformation (long currentTime, Transformation outTransformation)

public Matrix getMatrix ()

public void getValues (float[] values)

So for example (some pseudo code. I have not tested this):

Transformation outTransformation = new Transformation();
myAnimation.getTransformation(currentTime, outTransformation);
Matrix transformationMatrix = outTransformation.getMatrix();
float[] matrixValues = new float[9];
transformationMatrix.getValues(matrixValues);
float transX = matrixValues[Matrix.MTRANS_X];
float transY = matrixValues[Matrix.MTRANS_Y];

Here is my function for finding multiple occurrences. Unlike the other solutions here, it supports the optional start and end parameters for slicing, just like str.index:

def all_substring_indexes(string, substring, start=0, end=None):
    result = []
    new_start = start
    while True:
        try:
            index = string.index(substring, new_start, end)
        except ValueError:
            return result
        else:
            result.append(index)
            new_start = index + len(substring)

An additional consideraion that I have not seen in the answers already given, is that included columns can be of data types that are not allowed as index key columns, such as varchar(max).

This allows you to include such columns in a covering index. I recently had to do this to provide a nHibernate generated query, which had a lot of columns in the SELECT, with a useful index.

Create a migration file

rails generate migration add_references_to_uploads user:references

Default foreign key name

This would create a user_id column in uploads table as a foreign key

class AddReferencesToUploads < ActiveRecord::Migration[5.2]
  def change
    add_reference :uploads, :user, foreign_key: true
  end
end

user model:

class User < ApplicationRecord
  has_many :uploads
end

upload model:

class Upload < ApplicationRecord
  belongs_to :user
end

Customize foreign key name:

add_reference :uploads, :author, references: :user, foreign_key: true

This would create an author_id column in the uploads tables as the foreign key.

user model:

class User < ApplicationRecord
  has_many :uploads, foreign_key: 'author_id'
end

upload model:

class Upload < ApplicationRecord
  belongs_to :user
end

You can use overflow:auto;

You can also control the x or y axis individually with the overflow-x and overflow-y properties.

Example:

.content {overflow:auto;}
.content {overflow-y:auto;}
.content {overflow-x:auto;}

Add runat to the element in the markup

<div id="formSpinner" runat="server">
    <img src="images/spinner.gif">
    <p>Saving...</p>
</div

Then you can get to the control's class attributes by using formSpinner.Attributes("class") It will only be a string, but you should be able to edit it.

You can do it by MXBeans

public class Check {
    public static void main(String[] args) {
        MemoryMXBean memBean = ManagementFactory.getMemoryMXBean() ;
        MemoryUsage heapMemoryUsage = memBean.getHeapMemoryUsage();

        System.out.println(heapMemoryUsage.getMax()); // max memory allowed for jvm -Xmx flag (-1 if isn't specified)
        System.out.println(heapMemoryUsage.getCommitted()); // given memory to JVM by OS ( may fail to reach getMax, if there isn't more memory)
        System.out.println(heapMemoryUsage.getUsed()); // used now by your heap
        System.out.println(heapMemoryUsage.getInit()); // -Xms flag

        // |------------------ max ------------------------| allowed to be occupied by you from OS (less than xmX due to empty survival space)
        // |------------------ committed -------|          | now taken from OS
        // |------------------ used --|                    | used by your heap

    }
}

But remember it is equivalent to Runtime.getRuntime() (took depicted schema from here)

memoryMxBean.getHeapMemoryUsage().getUsed()      <=> runtime.totalMemory() - runtime.freeMemory()
memoryMxBean.getHeapMemoryUsage().getCommitted() <=> runtime.totalMemory()
memoryMxBean.getHeapMemoryUsage().getMax()       <=> runtime.maxMemory()

from javaDoc

init - represents the initial amount of memory (in bytes) that the Java virtual machine requests from the operating system for memory management during startup. The Java virtual machine may request additional memory from the operating system and may also release memory to the system over time. The value of init may be undefined.

used - represents the amount of memory currently used (in bytes).

committed - represents the amount of memory (in bytes) that is guaranteed to be available for use by the Java virtual machine. The amount of committed memory may change over time (increase or decrease). The Java virtual machine may release memory to the system and committed could be less than init. committed will always be greater than or equal to used.

max - represents the maximum amount of memory (in bytes) that can be used for memory management. Its value may be undefined. The maximum amount of memory may change over time if defined. The amount of used and committed memory will always be less than or equal to max if max is defined. A memory allocation may fail if it attempts to increase the used memory such that used > committed even if used <= max would still be true (for example, when the system is low on virtual memory).

If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:

• Bootstrap Datetime Picker 1

• Bootstrap Datetime Picker 2

The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.

.html() will replace everything.

.append() will just append at the end.

I just had the situation that I wanted this only for lines exceeding \linewidth, that is: Squeezing long lines slightly. Since it took me hours to figure this out, I would like to add it here.

I want to emphasize that scaling fonts in LaTeX is a deadly sin! In nearly every situation, there is a better way (e.g. multline of the mathtools package). So use it conscious.

In this particular case, I had no influence on the code base apart the preamble and some lines slightly overshooting the page border when I compiled it as an eBook-scaled pdf.

\usepackage{environ}         % provides \BODY
\usepackage{etoolbox}        % provides \ifdimcomp
\usepackage{graphicx}        % provides \resizebox

\newlength{\myl}
\let\origequation=\equation
\let\origendequation=\endequation

\RenewEnviron{equation}{
  \settowidth{\myl}{$\BODY$}                       % calculate width and save as \myl

The suggested edit queue is full for @tibor-udvari's excellent fetch answer, so I'll post my suggested edits as a new answer.

This function gets the content type from the header if returned, otherwise falls back on a settable default type.

async function getFileFromUrl(url, name, defaultType = 'image/jpeg'){
  const response = await fetch(url);
  const data = await response.blob();
  return new File([data], name, {
    type: response.headers.get('content-type') || defaultType,
  });
}

// `await` can only be used in an async body, but showing it here for simplicity.
const file = await getFileFromUrl('https://example.com/image.jpg', 'example.jpg');

I'd highly suggest using CsvHelper.

Here's a quick example:

public class csvExampleClass
{
    public string Id { get; set; }
    public string Firstname { get; set; }
    public string Lastname { get; set; }
}

var items = DeserializeCsvFile<List<csvExampleClass>>( csvText );

public static List<T> DeserializeCsvFile<T>(string text)
{
    CsvReader csv = new CsvReader( new StringReader( text ) );
    csv.Configuration.Delimiter = ",";
    csv.Configuration.HeaderValidated = null;
    csv.Configuration.MissingFieldFound = null;
    return (List<T>)csv.GetRecords<T>();
}

Full documentation can be found at: https://joshclose.github.io/CsvHelper

Give your form an id only, and your input a name only:

<form id="myform">
  <input type="text" name="foo">

Then the most standards-compliant and least problematic way to access your input element is via:

document.getElementById("myform").elements["foo"]

using .elements["foo"] instead of just .foo is preferable because the latter might return a property of the form named "foo" rather than a HTML element!

You could learn about Python loops here: http://en.wikibooks.org/wiki/Python_Programming/Loops

You have to know that Python doesn't have { and } for start and end of loop, instead it depends on tab chars you enter in first of line, I mean line indents.

So you can do loop inside loop with double tab (indent)

An example of double loop is like this:

onetoten = range(1,11)
tentotwenty = range(10,21)
for count in onetoten:
    for count2 in tentotwenty
        print(count2)

Hmm, Arraylist can be used in cases like follows I guess:

1. you are not sure how many elements will be present
2. but you need to access all the elements randomly through indexing

For eg, you need to import and access all elements in a contact list (the size of which is unknown to you)

In order to have this result:

{"aoColumnDefs":[{"aTargets":[0],"aDataSort":[0,1]},{"aTargets":[1],"aDataSort":[1,0]},{"aTargets":[2],"aDataSort":[2,3,4]}]}

that holds the same data as:

  {
    "aoColumnDefs": [
     { "aDataSort": [ 0, 1 ], "aTargets": [ 0 ] },
     { "aDataSort": [ 1, 0 ], "aTargets": [ 1 ] },
     { "aDataSort": [ 2, 3, 4 ], "aTargets": [ 2 ] }
   ]
  }

you could use this code:

    JSONObject jo = new JSONObject();
    Collection<JSONObject> items = new ArrayList<JSONObject>();

    JSONObject item1 = new JSONObject();
    item1.put("aDataSort", new JSONArray(0, 1));
    item1.put("aTargets", new JSONArray(0));
    items.add(item1);
    JSONObject item2 = new JSONObject();
    item2.put("aDataSort", new JSONArray(1, 0));
    item2.put("aTargets", new JSONArray(1));
    items.add(item2);
    JSONObject item3 = new JSONObject();
    item3.put("aDataSort", new JSONArray(2, 3, 4));
    item3.put("aTargets", new JSONArray(2));
    items.add(item3);

    jo.put("aoColumnDefs", new JSONArray(items));

    System.out.println(jo.toString());

Localstorage is attached on the global window. When we log localstorage in the chrome devtools we see that it has the following APIs:

We can use the following API's for deleting items:

1. localStorage.clear(): Clears the whole localstorage
2. localStorage.removeItem('myItem'): To remove individual items

The correct way is to edit your php.ini file. Edit memory_limit to your desire value.

As from your question, 128M (which is the default limit) has been exceeded, so there is something seriously wrong with your code as it should not take that much.

If you know why it takes that much and you want to allow it set memory_limit = 512M or higher and you should be good.

Why not show create table myTable ?

Someone told me this but I didn't see anyone mention here, anything bad?

It's neat if you just want to take a glance at the indexes along with column infomations.

You should use <label for=""> for the checkboxes or radios, and to align checkboxes vertical-align is enough

Try changing your markup to this

<li>
    <input id="checkid" type="checkbox" value="test" />
    <label for="checkid">testdata</label>
</li>

<li>
    <input id="checkid2" type="checkbox" value="test" />
    <label for="checkid2">testdata 2</label>
</li>

And set CSS like

input[type="checkbox"]
{
    vertical-align:middle;
}

In case of long text

label,input{
    display: inline-block;
    vertical-align: middle;
}

Side note: In label, value of for must be the id of checkbox.

Working off of kennebec's answer, I created a prototype function which will return -1 if the nth occurence is not found rather than 0.

String.prototype.nthIndexOf = function(pattern, n) {
    var i = -1;

    while (n-- && i++ < this.length) {
        i = this.indexOf(pattern, i);
        if (i < 0) break;
    }

    return i;
}

You can do it like this and you mod function will work perfect let me know if you want a code pen

  <div ng-repeat="icon in icons">                   
                <div class="row" ng-if="$index % 3 == 0 ">
                    <i class="col col-33 {{icons[$index + n].icon}} custom-icon"></i>
                    <i class="col col-33 {{icons[$index + n + 1].icon}} custom-icon"></i>
                    <i class="col col-33 {{icons[$index + n + 2].icon}} custom-icon"></i>

Try getting Spring to inject it, assuming you're using Spring as a dependency-injection framework.

In your class, do something like this:

public void setSqlResource(Resource sqlResource) {
    this.sqlResource = sqlResource;
}

And then in your application context file, in the bean definition, just set a property:

<bean id="someBean" class="...">
    <property name="sqlResource" value="classpath:com/somecompany/sql/sql.txt" />
</bean>

And Spring should be clever enough to load up the file from the classpath and give it to your bean as a resource.

You could also look into PropertyPlaceholderConfigurer, and store all your SQL in property files and just inject each one separately where needed. There are lots of options.

As an analogy consider a water pipe as a channel. Pipe diameter corresponds to bandwidth or capacity, and pipe contents corresponds to throughput or usage. In the following image we can see three pipes (or channels), all of which are under-utilised, hence, usage could be increased without the need for a bigger pipe.

If you are expecting double, decimal, float, integer why not use the one which accomodates all namely decimal (128 bits are enough for most numbers you are looking at).

instead of (double)value use decimal.Parse(value.ToString()) or Convert.ToDecimal(value)

I was facing the same error. The solution that worked for me is:

From the server end, while returning JSON response, change the content-type: text/html

Now the browsers (Chrome, Firefox and IE8) do not give an error.

I use Node.Js and had the same problem... I solved just adding a '/' in the beggining of every script and link to an css static file.

<link rel="stylesheet" href="/assets/css/bootstrap/bootstrap.min.css">

Spring-jpa creates the query using the entity manager, and Hibernate will ignore the fetch mode if the query was built by the entity manager.

The following is the work around that I used:

1. Implement a custom repository which inherits from SimpleJpaRepository

2. Override the method getQuery(Specification<T> spec, Sort sort):

   @Override
   protected TypedQuery<T> getQuery(Specification<T> spec, Sort sort) { 
       CriteriaBuilder builder = entityManager.getCriteriaBuilder();
       CriteriaQuery<T> query = builder.createQuery(getDomainClass());
   
       Root<T> root = applySpecificationToCriteria(spec, query);
       query.select(root);
   
       applyFetchMode(root);
   
       if (sort != null) {
           query.orderBy(toOrders(sort, root, builder));
       }
   
       return applyRepositoryMethodMetadata(entityManager.createQuery(query));
   }
   

   In the middle of the method, add applyFetchMode(root); to apply the fetch mode, to make Hibernate create the query with the correct join.

   (Unfortunately we need to copy the whole method and related private methods from the base class because there was no other extension point.)

3. Implement applyFetchMode:

   private void applyFetchMode(Root<T> root) {
       for (Field field : getDomainClass().getDeclaredFields()) {
   
           Fetch fetch = field.getAnnotation(Fetch.class);
   
           if (fetch != null && fetch.value() == FetchMode.JOIN) {
               root.fetch(field.getName(), JoinType.LEFT);
           }
       }
   }
   

Since the OP asked about CPU usage AND memory usage (accepted answer only shows technique to get cpu usage), I'd like to recommend the ActivityManager class and specifically the accepted answer from this question: How to get current memory usage in android?

Basically I was trying to get my code to have a middle section on a 'row' to auto-adjust to the content on both sides (in my case, a dotted line separator). Like @Michael_B suggested, the key is using display:flex on the row container and at least making sure your middle container on the row has a flex-grow value of at least 1 higher than the outer containers (if outer containers don't have any flex-grow properties applied, middle container only needs 1 for flex-grow).

Here's a pic of what I was trying to do and sample code for how I solved it.

.row {
  background: lightgray;
  height: 30px;
  width: 100%;
  display: flex;
  align-items:flex-end;
  margin-top:5px;
}
.left {
  background:lightblue;
}
.separator{
  flex-grow:1;
  border-bottom:dotted 2px black;
}
.right {
  background:coral;
}

<div class="row">
  <div class="left">Left</div>
  <div class="separator"></div>
  <div class="right">Right With Text</div>
</div>
<div class="row">
  <div class="left">Left With More Text</div>
  <div class="separator"></div>
  <div class="right">Right</div>
</div>
<div class="row">
  <div class="left">Left With Text</div>
  <div class="separator"></div>
  <div class="right">Right With More Text</div>
</div>

Use the shutil module.

copyfile(src, dst)

Copy the contents of the file named src to a file named dst. The destination location must be writable; otherwise, an IOError exception will be raised. If dst already exists, it will be replaced. Special files such as character or block devices and pipes cannot be copied with this function. src and dst are path names given as strings.

Take a look at filesys for all the file and directory handling functions available in standard Python modules.

Try this

<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="1" />

if you want 0 or 1 "description" elements, Or

<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="unbounded" />

if you want 0 to infinity number of "description" elements.

use js split() method to create an array

var keywords = $('#searchKeywords').val().split(",");

then loop through the array using jQuery.each() function. as the documentation says:

In the case of an array, the callback is passed an array index and a corresponding array value each time

$.each(keywords, function(i, keyword){
   console.log(keyword);
});

Take a look at BackgroundWorker Class, with the OnRunWorkerCompleted you can do it.

The xpath() function does not return a string. It returns an array with XML elements (of type SimpleXMLElement), which may be casted to a string.

if (count($message)) {
   if (strlen((string)$message[0]) < 141) {
      echo "There Are No Contests.";
   }
   else if(strlen((string)$message[0]) > 142) {
      echo "There is One Active Contest.";
   }
}

The setInterval method returns an interval ID that you need to pass to clearInterval in order to clear the interval. You're passing a function, which won't work. Here's an example of a working setInterval/clearInterval

var interval_id = setInterval(myMethod,500);
clearInterval(interval_id);

You should stick to the NSInteger data types when possible. So you'd create the number like that:

NSInteger myValue = 1;
NSNumber *number = [NSNumber numberWithInteger: myValue];

Decoding works with the integerValue method then:

NSInteger value = [number integerValue];

Try this piece of code:

try {        
    Log.e("log_tag", "Error in convert String" + result.toString());
    JSONObject json_data = new JSONObject(result);

    String status = json_data.getString("Status");
    {
        String data = json_data.getString("locations");
        JSONArray json_data1 = new JSONArray(data);
        for (int i = 0; i < json_data1.length(); i++) {
            json_data = json_data1.getJSONObject(i);

            String lat = json_data.getString("lat");
            String lng = json_data.getString("long");
        }
    }
}

You could try to reinstall the ca-certificates package, or explicitly allow the certificate in question as described here.

1. String otherString = "helen" + character;

2. otherString +=  character;

Evaluating "1,2,3" results in (1, 2, 3), a tuple. As you've discovered, tuples are immutable. Convert to a list before processing.

I am making an assumption that there is a counter already in place. in $i which is incremented at the end of a loop, This works for me using a shorthand query.

$row_pos = ($i & 1) ? 'odd' : 'even';

So what does this do, well it queries the statement we are making in essence $i is odd, depending whether its true or false will decide what gets returned. The returned value populates our variable $row_pos

My use of this is to place it inside the foreach loop, right before i need it, This makes it a very efficient one liner to give me the appropriate class names, this is because i already have a counter for the id's to make use of later in the program. This is a brief example of how i will use this part.

<div class='row-{$row_pos}'> random data <div>

This gives me odd and even classes on each row so i can use the correct class and stripe my printed results down the page.

The full example of what i use note the id has the counter applied to it and the class has my odd/even result applied to it.:

$i=0;
foreach ($a as $k => $v) {

    $row_pos = ($i & 1) ? 'odd' : 'even';
    echo "<div id='A{$i}' class='row-{$row_pos}'>{$v['f_name']} {$v['l_name']} - {$v['amount']} - {$v['date']}</div>\n";

$i++;
}

in summary, this gives me a very simple way to create a pretty table.

I find using pandas MultiIndex to be the best tool for the job. If you have a list of lists lists_list, call pd.MultiIndex.from_product(lists_list) and iterate over the result (or use it in DataFrame index).

Extending the answer already provided by Phil. Adding parallelism to it is a no brainer in bash if you use xargs for the call.

Here the code:

xargs -n1 -P 10 curl -o /dev/null --silent --head --write-out '%{url_effective}: %{http_code}\n' < url.lst

-n1: use just one value (from the list) as argument to the curl call

-P10: Keep 10 curl processes alive at any time (i.e. 10 parallel connections)

Check the write_out parameter in the manual of curl for more data you can extract using it (times, etc).

In case it helps someone this is the call I'm currently using:

xargs -n1 -P 10 curl -o /dev/null --silent --head --write-out '%{url_effective};%{http_code};%{time_total};%{time_namelookup};%{time_connect};%{size_download};%{speed_download}\n' < url.lst | tee results.csv

It just outputs a bunch of data into a csv file that can be imported into any office tool.

You can search "slashdot effect analysis" for graphs of what you would see if some aspect of the site suddenly became popular in the news, e.g. this graph on wiki.

Web-applications that survive tend to be the ones which can generate static pages instead of putting every request through a processing language.

There was an excellent video (I think it might have been on ted.com? I think it might have been by flickr web team? Does someone know the link?) with ideas on how to scale websites beyond the single server, e.g. how to allocate connections amongst the mix of read-only and read-write servers to get best effect for various types of users.

The information does exist - but not in the format you need, and only if you export your classes. This works in Windows, I don't know about other platforms. Using the storage-class specifiers as in, for example:

class __declspec(export) MyClass
{
public:
    void Foo(float x);
}

This makes the compiler build the class definition data into the DLL/Exe. But it's not in a format that you can readily use for reflection.

At my company we built a library that interprets this metadata, and allows you to reflect a class without inserting extra macros etc. into the class itself. It allows functions to be called as follows:

MyClass *instance_ptr=new MyClass;
GetClass("MyClass")->GetFunction("Foo")->Invoke(instance_ptr,1.331);

This effectively does:

instance_ptr->Foo(1.331);

The Invoke(this_pointer,...) function has variable arguments. Obviously by calling a function in this way you're circumventing things like const-safety and so on, so these aspects are implemented as runtime checks.

I'm sure the syntax could be improved, and it only works on Win32 and Win64 so far. We've found it really useful for having automatic GUI interfaces to classes, creating properties in C++, streaming to and from XML and so on, and there's no need to derive from a specific base class. If there's enough demand maybe we could knock it into shape for release.

When you overload in TypeScript, you only have one implementation with multiple signatures.

class Foo {
    myMethod(a: string);
    myMethod(a: number);
    myMethod(a: number, b: string);
    myMethod(a: any, b?: string) {
        alert(a.toString());
    }
}

Only the three overloads are recognized by TypeScript as possible signatures for a method call, not the actual implementation.

In your case, I would personally use two methods with different names as there isn't enough commonality in the parameters, which makes it likely the method body will need to have lots of "ifs" to decide what to do.

TypeScript 1.4

As of TypeScript 1.4, you can typically remove the need for an overload using a union type. The above example can be better expressed using:

myMethod(a: string | number, b?: string) {
    alert(a.toString());
}

The type of a is "either string or number".

Maybe not that good but I've figured this:

def order_dic(dic):
    ordered_dic={}
    key_ls=sorted(dic.keys())
    for key in key_ls:
        ordered_dic[key]=dic[key]
    return ordered_dic

You can try using FormulaLocal property instead of Formula. Then the semicolon should work.

Try installing the 32 bit version of Java 6. This works for version Install4J 4.0.5. Should fire right up, or allow you to re-run the installer.

Any newer version or the 64-bit version of 6 will fail, complaining that the java.exe is damaged.

What about 1.1E10, +1, -0, etc? Parsing all possible numbers is trickier than many people think. If you want to include as many numbers are possible you should use the to_number function in a PL/SQL function. From http://www.oracle-developer.net/content/utilities/is_number.sql:

CREATE OR REPLACE FUNCTION is_number (str_in IN VARCHAR2) RETURN NUMBER IS
   n NUMBER;
BEGIN
   n := TO_NUMBER(str_in);
   RETURN 1;
EXCEPTION
   WHEN VALUE_ERROR THEN
      RETURN 0;
END;
/

It's a buzzword that refers to things like the normal Web architecture with e.g., Javascript - ASP.Net - Middleware - Database layer. Each of these things is a "tier".

This is the benchmark I have run after finding some articles around the net.

    b.report("re =~ str\t")    { N.times { re =~ str } }
    b.report("re.match str\t") { N.times { re.match str } }
    if re.respond_to?(:match?)
        b.report("re.match? str\t") { N.times { re.match? str } }
    end
end

You can create a reusable function to do it with any arguments, the simplest one is something like this:

function sortArgs() {
  return [...arguments].sort();
}

sortArgs('ali', 'reza', 1, 2, 'a'); //[1, 2, "a", "ali", "reza"];

Spread syntax can be used in ES6 and above...

But if you'd like to use something compatible with ES5 and below, you can use Array.prototype.slice.call, so you code looks like this:

function sortArgs() {
  return Array.prototype.slice.call(arguments).sort();
}

sortArgs('ali', 'reza', 1, 2, 'a'); //[1, 2, "a", "ali", "reza"];

There are also few other ways to do this, for Example using Array.from or loop through the arguments and assign them to a new array...

String fname = ((EditText)findViewById(R.id.txtFirstName)).getText().toString();
String lname = ((EditText)findViewById(R.id.txtLastName)).getText().toString();
((EditText)findViewById(R.id.txtFullName)).setText(fname + " "+lname);

TLDR; Pandas groupby.agg has a new, easier syntax for specifying (1) aggregations on multiple columns, and (2) multiple aggregations on a column. So, to do this for pandas >= 0.25, use

df.groupby('dummy').agg(Mean=('returns', 'mean'), Sum=('returns', 'sum'))

           Mean       Sum
dummy                    
1      0.036901  0.369012

OR

df.groupby('dummy')['returns'].agg(Mean='mean', Sum='sum')

           Mean       Sum
dummy                    
1      0.036901  0.369012

Pandas >= 0.25: Named Aggregation

Pandas has changed the behavior of GroupBy.agg in favour of a more intuitive syntax for specifying named aggregations. See the 0.25 docs section on Enhancements as well as relevant GitHub issues GH18366 and GH26512.

From the documentation,

To support column-specific aggregation with control over the output column names, pandas accepts the special syntax in GroupBy.agg(), known as “named aggregation”, where

• The keywords are the output column names
• The values are tuples whose first element is the column to select and the second element is the aggregation to apply to that column. Pandas provides the pandas.NamedAgg namedtuple with the fields ['column', 'aggfunc'] to make it clearer what the arguments are. As usual, the aggregation can be a callable or a string alias.

You can now pass a tuple via keyword arguments. The tuples follow the format of (<colName>, <aggFunc>).

import pandas as pd

pd.__version__                                                                                                                            
# '0.25.0.dev0+840.g989f912ee'

# Setup
df = pd.DataFrame({'kind': ['cat', 'dog', 'cat', 'dog'],
                   'height': [9.1, 6.0, 9.5, 34.0],
                   'weight': [7.9, 7.5, 9.9, 198.0]
})

df.groupby('kind').agg(
    max_height=('height', 'max'), min_weight=('weight', 'min'),)

      max_height  min_weight
kind                        
cat          9.5         7.9
dog         34.0         7.5

Alternatively, you can use pd.NamedAgg (essentially a namedtuple) which makes things more explicit.

df.groupby('kind').agg(
    max_height=pd.NamedAgg(column='height', aggfunc='max'), 
    min_weight=pd.NamedAgg(column='weight', aggfunc='min')
)

      max_height  min_weight
kind                        
cat          9.5         7.9
dog         34.0         7.5

It is even simpler for Series, just pass the aggfunc to a keyword argument.

df.groupby('kind')['height'].agg(max_height='max', min_height='min')    

      max_height  min_height
kind                        
cat          9.5         9.1
dog         34.0         6.0       

Lastly, if your column names aren't valid python identifiers, use a dictionary with unpacking:

df.groupby('kind')['height'].agg(**{'max height': 'max', ...})

Pandas < 0.25

In more recent versions of pandas leading upto 0.24, if using a dictionary for specifying column names for the aggregation output, you will get a FutureWarning:

df.groupby('dummy').agg({'returns': {'Mean': 'mean', 'Sum': 'sum'}})
# FutureWarning: using a dict with renaming is deprecated and will be removed 
# in a future version

Using a dictionary for renaming columns is deprecated in v0.20. On more recent versions of pandas, this can be specified more simply by passing a list of tuples. If specifying the functions this way, all functions for that column need to be specified as tuples of (name, function) pairs.

df.groupby("dummy").agg({'returns': [('op1', 'sum'), ('op2', 'mean')]})

        returns          
            op1       op2
dummy                    
1      0.328953  0.032895

Or,

df.groupby("dummy")['returns'].agg([('op1', 'sum'), ('op2', 'mean')])

            op1       op2
dummy                    
1      0.328953  0.032895

sed -n 's/^potato:[[:space:]]*//p' file.txt

One can think of Grep as a restricted Sed, or of Sed as a generalized Grep. In this case, Sed is one good, lightweight tool that does what you want -- though, of course, there exist several other reasonable ways to do it, too.

I think the problem is that in the debug visual studio don't use the normal exeName.

it use indtead "NameApplication".host.exe

so the name of the config file is "NameApplication".host.exe.config and not "NameApplication".exe.config

and after the application close - it return to the back app.config

so if you check the wrong file or you check on the wrong time you will see that nothing changed.

Just execute the set command in your command line. Then you see all the environments variables you have set.

Or if on Unix you can simplify it:

$ set | grep "JAVA_HOME" 

document.getElementById('tries').scrollIntoView() works. This works better than window.location.hash when you have fixed positioning.

If you want the indentation, you have to specify it to the TransformerFactory.

TransformerFactory tf = TransformerFactory.newInstance();
tf.setAttribute("indent-number", new Integer(2));
Transformer t = tf.newTransformer();

I also want to know is it possible to push the compiled binary into android device or AVD and run using the terminal of the android device or AVD?

here you can see NestedVM

NestedVM provides binary translation for Java Bytecode. This is done by having GCC compile to a MIPS binary which is then translated to a Java class file. Hence any application written in C, C++, Fortran, or any other language supported by GCC can be run in 100% pure Java with no source changes.

Example: Cross compile Hello world C program and run it on android

Swift 3 & 4/5

self.navigationController!.viewControllers.removeAll()

self.navigationController?.viewControllers.remove(at: "insert here a number")

Swift 2.1

remove all:

self.navigationController!.viewControllers.removeAll()

remove at index

self.navigationController?.viewControllers.removeAtIndex("insert here a number")

There a bunch of more possible actions like removeFirst,range etc.

I had the same problem. In my case git could not find the global variable %HTTP_PROXY%, simply because Windows was not providing/using it.

I solved it by excluding the variable from the git config file (located in %USERPROFILE%\.gitconfig):

[http]
#   proxy = %HTTP_PROXY%

Actually the easiest way to do that would be to pass kill arguments like below:

ps -ef | grep your_process_name | grep -v grep | awk '{print $2}' | xargs kill

Hope it helps.

How about the Mersenne Twister? The boost implementation is rather easy to use and is well tested in many real-world applications. I've used it myself in several academic projects such as artificial intelligence and evolutionary algorithms.

Here's their example where they make a simple function to roll a six-sided die:

#include <boost/random/mersenne_twister.hpp>
#include <boost/random/uniform_int.hpp>
#include <boost/random/variate_generator.hpp>

boost::mt19937 gen;

int roll_die() {
    boost::uniform_int<> dist(1, 6);
    boost::variate_generator<boost::mt19937&, boost::uniform_int<> > die(gen, dist);
    return die();
}

Oh, and here's some more pimping of this generator just in case you aren't convinced you should use it over the vastly inferior rand():

The Mersenne Twister is a "random number" generator invented by Makoto Matsumoto and Takuji Nishimura; their website includes numerous implementations of the algorithm.

Essentially, the Mersenne Twister is a very large linear-feedback shift register. The algorithm operates on a 19,937 bit seed, stored in an 624-element array of 32-bit unsigned integers. The value 2^19937-1 is a Mersenne prime; the technique for manipulating the seed is based on an older "twisting" algorithm -- hence the name "Mersenne Twister".

An appealing aspect of the Mersenne Twister is its use of binary operations -- as opposed to time-consuming multiplication -- for generating numbers. The algorithm also has a very long period, and good granularity. It is both fast and effective for non-cryptographic applications.

Here .persist() only will insert the record.If we use .merge() it will check is there any record exist with the current ID, If it exists, it will update otherwise it will insert a new record.

Use document.activeElement, it is supported in all major browsers.

Previously, if you were trying to find out what form field has focus, you could not. To emulate detection within older browsers, add a "focus" event handler to all fields and record the last-focused field in a variable. Add a "blur" handler to clear the variable upon a blur event for the last-focused field.

If you need to remove the activeElement you can use blur; document.activeElement.blur(). It will change the activeElement to body.

ValueError: cannot convert float NaN to integer

From v0.24, you actually can. Pandas introduces Nullable Integer Data Types which allows integers to coexist with NaNs.

Given a series of whole float numbers with missing data,

s = pd.Series([1.0, 2.0, np.nan, 4.0])
s

0    1.0
1    2.0
2    NaN
3    4.0
dtype: float64

s.dtype
# dtype('float64')

You can convert it to a nullable int type (choose from one of Int16, Int32, or Int64) with,

s2 = s.astype('Int32') # note the 'I' is uppercase
s2

0      1
1      2
2    NaN
3      4
dtype: Int32

s2.dtype
# Int32Dtype()

Your column needs to have whole numbers for the cast to happen. Anything else will raise a TypeError:

s = pd.Series([1.1, 2.0, np.nan, 4.0])

s.astype('Int32')
# TypeError: cannot safely cast non-equivalent float64 to int32

numpy.dot(a, b, out=None)

Dot product of two arrays.

For N dimensions it is a sum product over the last axis of a and the second-to-last of b.

Documentation: numpy.dot.

If Chrome DevTools is reporting a 404 for a .map file (maybe jquery-1.10.2.min.map, jquery.min.map or jquery-2.0.3.min.map, but can happen with anything) first thing to know is this is only requested when using the DevTools. Your users will not be hitting this 404.

Now you can fix this or disable the sourcemap functionality.

Fix: get the files

Next, it's an easy fix. Head to http://jquery.com/download/ and click the Download the map file link for your version, and you'll want the uncompressed file downloaded as well.

Having the map file in place allows you do debug your minified jQuery via the original sources, which will save a lot of time and frustration if you don't like dealing with variable names like a and c.

More about sourcemaps here: An Introduction to JavaScript Source Maps

Dodge: disable sourcemaps

Instead of getting the files, you can alternatively disable JavaScript source maps completely for now, in your settings. This is a fine choice if you never plan on debugging JavaScript on this page. Use the cog icon in the bottom right of the DevTools, to open settings, then:

Current Example:

You need to define border-width:1px

Your code should read:

$(this).css({"border-color": "#C1E0FF", 
             "border-width":"1px", 
             "border-style":"solid"});

Suggested Example:

You should ideally use a class and addClass/removeClass

$(this).addClass('borderClass'); $(this).removeClass('borderClass');

and in your CSS:

.borderClass{
  border-color: #C1E0FF;
  border-width:1px;
  border-style: solid;
  /** OR USE INLINE
  border: 1px solid #C1E0FF;
  **/
}

jsfiddle working example: http://jsfiddle.net/gorelative/tVbvF/\

jsfiddle with animate: http://jsfiddle.net/gorelative/j9Xxa/ This just gives you an example of how it could work, you should get the idea.. There are better ways of doing this most likely.. like using a toggle()

You can define a global alias so you can invoke a short log in a more comfortable way:

git config --global alias.slog "log --pretty=oneline --abbrev-commit"

Then you can call it using git slog (it even works with autocompletion if you have it enabled).

Many answers here already mention

You can cast null to any reference type

and

If the argument is null, then a string equal to "null"

I wondered where that is specified and looked it up the Java Specification:

The null reference can always be assigned or cast to any reference type (§5.2, §5.3, §5.5).

If the reference is null, it is converted to the string "null" (four ASCII characters n, u, l, l).

JavaScript is now evolving and growing it has now good and best even efficient way to check it

Here are some easy ways to check if object has a particular property:

1. Using hasOwnProperty()

const hero = {
  name: 'Batman'
};

hero.hasOwnProperty('name');     // => true
hero.hasOwnProperty('realName'); // => false

2. Using keyword/operator in

const hero = {
  name: 'Batman'
};

'name' in hero;     // => true
'realName' in hero; // => false

3. Comparing with undefined keyword

const hero = {
  name: 'Batman'
};

hero.name;     // => 'Batman'
hero.realName; // => undefined

// So consider this
hero.realName == undefined // => true (which means property does not exists in object)
hero.name == undefined // => false (which means that property exists in object)

For more information, check here.

CODE SNIPPET:

extension UIView {

  // OUTPUT 1
  func dropShadow(scale: Bool = true) {
    layer.masksToBounds = false
    layer.shadowColor = UIColor.black.cgColor
    layer.shadowOpacity = 0.5
    layer.shadowOffset = CGSize(width: -1, height: 1)
    layer.shadowRadius = 1

    layer.shadowPath = UIBezierPath(rect: bounds).cgPath
    layer.shouldRasterize = true
    layer.rasterizationScale = scale ? UIScreen.main.scale : 1
  }

  // OUTPUT 2
  func dropShadow(color: UIColor, opacity: Float = 0.5, offSet: CGSize, radius: CGFloat = 1, scale: Bool = true) {
    layer.masksToBounds = false
    layer.shadowColor = color.cgColor
    layer.shadowOpacity = opacity
    layer.shadowOffset = offSet
    layer.shadowRadius = radius

    layer.shadowPath = UIBezierPath(rect: self.bounds).cgPath
    layer.shouldRasterize = true
    layer.rasterizationScale = scale ? UIScreen.main.scale : 1
  }
}

NOTE: If you don't pass any parameter to that function, then the scale argument will be true by default. You can define a default value for any parameter in a function by assigning a value to the parameter after that parameter’s type. If a default value is defined, you can omit that parameter when calling the function.

OUTPUT 1:

shadowView.dropShadow()

OUTPUT 2:

shadowView.dropShadow(color: .red, opacity: 1, offSet: CGSize(width: -1, height: 1), radius: 3, scale: true)

layer.shouldRasterize = true will make the shadow static and cause a shadow for the initial state of the UIView. So I would recommend not to use layer.shouldRasterize = true in dynamic layouts like view inside a UITableViewCell.

Obviously, of the two methods you mention number 1 is more efficient, since it only needs to go through the list once, while with method number 2 the list has to be traversed two times (first to find the elements to remove, and them to remove them).

Actually, removing a list of elements from another list is likely an algorithm that's worse than O(n) so method 2 is even worse.

The iterator method:

List data = ...;

for (Iterator i = data.iterator(); i.hasNext(); ) {
    Object element = i.next();

    if (!(...)) {
        i.remove();
    }
}

When debugging lines of code, here are the usual scenarios:

• (Step Into) A method is about to be invoked, and you want to debug into the code of that method, so the next step is to go into that method and continue debugging step-by-step.
• (Step Over) A method is about to be invoked, but you're not interested in debugging this particular invocation, so you want the debugger to execute that method completely as one entire step.
• (Step Return) You're done debugging this method step-by-step, and you just want the debugger to run the entire method until it returns as one entire step.
• (Resume) You want the debugger to resume "normal" execution instead of step-by-step
• (Line Breakpoint) You don't care how it got there, but if execution reaches a particular line of code, you want the debugger to temporarily pause execution there so you can decide what to do.

Eclipse has other advanced debugging features, but these are the basic fundamentals.

I have written a small module to do just that, called timexe:

• Its simple,small reliable code and has no dependencies
• Resolution is in milliseconds and has high precision over time
• Cron like, but not compatible (reversed order and other Improvements)
• I works in the browser too

Install:

npm install timexe

use:

var timexe = require('timexe');
//Every 30 sec
var res1=timexe(”* * * * * /30”, function() console.log(“Its time again”)});

//Every minute
var res2=timexe(”* * * * *”,function() console.log(“a minute has passed”)});

//Every 7 days
var res3=timexe(”* y/7”,function() console.log(“its the 7th day”)});

//Every Wednesdays 
var res3=timexe(”* * w3”,function() console.log(“its Wednesdays”)});

// Stop "every 30 sec. timer"
timexe.remove(res1.id);

you can achieve start/stop functionality by removing/re-adding the entry directly in the timexe job array. But its not an express function.

It's cleaner/safer to use the getters provided by google instead of accessing the properties like some did

google.maps.event.addListener(drawingManager, 'overlaycomplete', function(polygon) {
    var coordinatesArray = polygon.overlay.getPath().getArray();
});

The raw_json_encode() function above did not solve me the problem (for some reason, the callback function raised an error on my PHP 5.2.5 server).

But this other solution did actually work.

https://www.experts-exchange.com/questions/28628085/json-encode-fails-with-special-characters.html

Credits should go to Marco Gasi. I just call his function instead of calling json_encode():

function jsonRemoveUnicodeSequences( $json_struct )
{ 
    return preg_replace( "/\\\\u([a-f0-9]{4})/e", "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode( $json_struct ) );
}

This works for me across all mobile devices in both portrait and landscape modes.

For Windows:

• Right click on 'My Computers' and open 'Properties'.
• In Windows Vista or Windows 7, go to "Advanced System Settings". Else go to next step.
• Go to 'Advanced Tab' and click on Environment Variables button.
• Select 'Path' under the list of 'System Variables', and press Edit and add C:\Program Files\java\jdk\bin after a semicolon.
• Now click on 'new' button under system variables and enter 'JAVA_HOME' as variable name and path to jdk home directory (ex. 'C:\Program Files\Java\jdk1.6.0_24' if you are installing java version 6. Directory name may change with diff. java versions) as variable_value.

There is a very efficient method to determine if a element's size has been changed.

This library has a class ResizeSensor which can be used for resize detection.
It uses an event-based approach, so it's damn fast and doesn't waste CPU time.

Example:

new ResizeSensor(jQuery('#divId'), function(){ 
    console.log('content dimension changed');
});

Please do not use the jQuery onresize plugin as it uses setTimeout() in combination with reading the DOM clientHeight/clientWidth properties in a loop to check for changes.
This is incredible slow and inaccurate since it causes layout thrashing.

Disclosure: I am directly associated with this library.

You can use >> to print in another file.

echo "hello" >> logfile.txt

i also faced similar issue. I could able to solve this by setting JAVA_HOME in Environment variable in windows. Setting JAVA_HOME in batch file is not working in this case.

in my problem I want the text of anchor <a>text</a> inside my view to be based on some value and that text is retrieved form App string Resources

so, this @() is the solution

<a href='#'>
      @(Model.ID == 0 ? Resource_en.Back : Resource_en.Department_View_DescartChanges)
</a>

if the text is not from App string Resources use this

@(Model.ID == 0 ? "Back" :"Descart Changes")

Why do you not use the java functionality for that:

If your numbers are small (smaller than yours) you could use: Integer.parseInt(hex, 16) to convert a Hex - String into an integer.

  String hex = "ff"
  int value = Integer.parseInt(hex, 16);  

For big numbers like yours, use public BigInteger(String val, int radix)

  BigInteger value = new BigInteger(hex, 16);

@See JavaDoc:

• Integer.parseInt(String value, int radix)
• BigInteger(String value, int radix)

If you need to use a double number:

keyboardType: TextInputType.numberWithOptions(decimal: true),
inputFormatters: [FilteringTextInputFormatter.allow(RegExp('[0-9.,]')),],
onChanged: (value) => doubleVar = double.parse(value),

RegExp('[0-9.,]') allows for digits between 0 and 9, also comma and dot.

double.parse() converts from string to double.

Don't forget you need: import 'package:flutter/services.dart';

The basic idea is that instead of having an ongoing connection to the server, you make a request, get some data, show that to a user, but maybe not all of it, and then when the user does something which calls for more data, or to pass some up to the server, the client initiates a change to a new state.

I tested below code with SQL Server 2008 R2 Express and I believe we should have solution for all 6 steps you outlined. Let's take on them one-by-one:

1 - Enable TCP/IP

We can enable TCP/IP protocol with WMI:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProtocols = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocol " _
    & "where InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'")

if tcpProtocols.Count = 1 then
    ' set tcpProtocol = tcpProtocols(0)
    ' I wish this worked, but unfortunately 
    ' there's no int-indexed Item property in this type

    ' Doing this instead
    for each tcpProtocol in tcpProtocols
        dim setEnableResult
            setEnableResult = tcpProtocol.SetEnable()
            if setEnableResult <> 0 then 
                Wscript.Echo "Failed!"
            end if
    next
end if

2 - Open the right ports in the firewall

I believe your solution will work, just make sure you specify the right port. I suggest we pick a different port than 1433 and make it a static port SQL Server Express will be listening on. I will be using 3456 in this post, but please pick a different number in the real implementation (I feel that we will see a lot of applications using 3456 soon :-)

3 - Modify TCP/IP properties enable a IP address

We can use WMI again. Since we are using static port 3456, we just need to update two properties in IPAll section: disable dynamic ports and set the listening port to 3456:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProperties = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocolProperty " _
    & "where InstanceName='SQLEXPRESS' and " _
    & "ProtocolName='Tcp' and IPAddressName='IPAll'")

for each tcpProperty in tcpProperties
    dim setValueResult, requestedValue

    if tcpProperty.PropertyName = "TcpPort" then
        requestedValue = "3456"
    elseif tcpProperty.PropertyName ="TcpDynamicPorts" then
        requestedValue = ""
    end if

    setValueResult = tcpProperty.SetStringValue(requestedValue)
    if setValueResult = 0 then 
        Wscript.Echo "" & tcpProperty.PropertyName & " set."
    else
        Wscript.Echo "" & tcpProperty.PropertyName & " failed!"
    end if
next

Note that I didn't have to enable any of the individual addresses to make it work, but if it is required in your case, you should be able to extend this script easily to do so.

Just a reminder that when working with WMI, WBEMTest.exe is your best friend!

4 - Enable mixed mode authentication in sql server

I wish we could use WMI again, but unfortunately this setting is not exposed through WMI. There are two other options:

1. Use LoginMode property of Microsoft.SqlServer.Management.Smo.Server class, as described here.

2. Use LoginMode value in SQL Server registry, as described in this post. Note that by default the SQL Server Express instance is named SQLEXPRESS, so for my SQL Server 2008 R2 Express instance the right registry key was HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQLServer.

5 - Change user (sa) default password

You got this one covered.

6 - Finally (connect to the instance)

Since we are using a static port assigned to our SQL Server Express instance, there's no need to use instance name in the server address anymore.

SQLCMD -U sa -P newPassword -S 192.168.0.120,3456

Please let me know if this works for you (fingers crossed!).

Maybe I am missing something here, but did you allocate any memory for that PString before you accessed it?

PString * initializeString() {
    PString *str;
    str = (PString *) malloc(sizeof(PString));
    str->length = &length;
    return str;
}

A function returns a value and a procedure just executes commands.

The name function comes from math. It is used to calculate a value based on input.

A procedure is a set of commands which can be executed in order.

In most programming languages, even functions can have a set of commands. Hence the difference is only returning a value.

But if you like to keep a function clean, (just look at functional languages), you need to make sure a function does not have a side effect.

Most of the time unreachable commits are in the reflog. So, the first thing to try is to look at the reflog using the command git reflog (which display the reflog for HEAD).

Perhaps something easier if the commit was part of a specific branch still existing is to use the command git reflog name-of-my-branch. It works also with a remote, for example if you forced push (additional advice: always prefer git push --force-with-lease instead that better prevent mistakes and is more recoverable).

If your commits are not in your reflog (perhaps because deleted by a 3rd party tool that don't write in the reflog), I successfully recovered a branch by reseting my branch to the sha of the commit found using a command like that (it creates a file with all the dangling commits):

git fsck --full --no-reflogs --unreachable --lost-found | grep commit | cut -d\  -f3 | xargs -n 1 git log -n 1 --pretty=oneline > .git/lost-found.txt

If you should use it more than one time (or want to save it somewhere), you could also create an alias with that command...

git config --global alias.rescue '!git fsck --full --no-reflogs --unreachable --lost-found | grep commit | cut -d\  -f3 | xargs -n 1 git log -n 1 --pretty=oneline > .git/lost-found.txt'

and use it with git rescue

To investigate found commits, you could display each commit using some commands to look into them.

To display the commit metadata (author, creation date and commit message):

git cat-file -p 48540dfa438ad8e442b18e57a5a255c0ecad0560

To see also the diffs:

git log -p 48540dfa438ad8e442b18e57a5a255c0ecad0560

Once you found your commit, then create a branch on this commit with:

git branch commit_rescued 48540dfa438ad8e442b18e57a5a255c0ecad0560

For the ones that are under Windows and likes GUIs, you could easily recover commits (and also uncommited staged files) with GitExtensions by using the feature Repository => Git maintenance => Recover lost objects...

A similar command to easily recover staged files deleted: https://stackoverflow.com/a/58853981/717372

Normal multiplication like you showed:

>>> import numpy as np
>>> m = np.array([[1,2,3],[4,5,6],[7,8,9]])
>>> c = np.array([0,1,2])
>>> m * c
array([[ 0,  2,  6],
       [ 0,  5, 12],
       [ 0,  8, 18]])

If you add an axis, it will multiply the way you want:

>>> m * c[:, np.newaxis]
array([[ 0,  0,  0],
       [ 4,  5,  6],
       [14, 16, 18]])

You could also transpose twice:

>>> (m.T * c).T
array([[ 0,  0,  0],
       [ 4,  5,  6],
       [14, 16, 18]])

try this:-

http://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss.SSS");
Date date = new Date();
System.out.println(dateFormat.format(date));

or

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Calendar cal = Calendar.getInstance();
System.out.println(dateFormat.format(cal.getTime()));

Well presumably it's not using the same version of Java when running it externally. Look through the startup scripts carefully to find where it picks up the version of Java to run. You should also check the startup logs to see whether they indicate which version is running.

Alternatively, unless you need the Java 7 features, you could always change your compiler preferences in Eclipse to target 1.6 instead.

The problem with the accepted answer is that it cannot signal failure. There's strtol (STRing TO Long) which can. It's part of a larger family: wcstol (Wide Character String TO Long, e.g. Unicode), strtoull (TO Unsigned Long Long, 64bits+), wcstoull, strtof (TO Float) and wcstof.

For me, I am working on .net 4.5.2 with web api 2.0, I have the same error, i set it just by adding requestPathInvalidCharacters="" in the requestPathInvalidCharacters you have to set not allowed characters else you have to remove characters that cause this problem.

<system.web>
     <httpRuntime targetFramework="4.5.2" requestPathInvalidCharacters="" />
     <pages  >
      <namespaces>
     ....
 </namespaces>
    </pages> 
  </system.web>

**Note that it is not a good practice, may be a post with this parameter as attribute of an object is better or try to encode the special character. -- After searching on best practice for designing rest api, i found that in search, sort and paginnation, we have to handle the query parameter like this

/companies?search=Digital%26Mckinsey

and this solve the problem when we encode & and remplace it on the url by %26 any way, on the server we receive the correct parameter Digital&Mckinsey

(This is paraphrased from the MS Access help files. I'm sure XL has something similar.) Basically, TimerInterval is a form-level property. Once set, use the sub Form_Timer to carry out your intended action.

Sub Form_Load()
    Me.TimerInterval = 1000 '1000 = 1 second
End Sub

Sub Form_Timer()
    'Do Stuff
End Sub

Try this:

var date = new Date();
console.log(date instanceof Date && !isNaN(date.valueOf()));

This should return true.

UPDATED: Added isNaN check to handle the case commented by Julian H. Lam

Look at the getFragmentManager().popBackStack() methods (there are several to choose from)

END;

As Sonars sonar.jacoco.reportPath, sonar.jacoco.itReportPath and sonar.jacoco.reportPaths have all been deprecated, you should use sonar.coverage.jacoco.xmlReportPaths now. This also has some impact if you want to configure a multi module maven project with Sonar and Jacoco.

As @Lonzak pointed out, since Sonar 0.7.7, you can use Sonars report aggragation goal. Just put in you parent pom the following dependency:

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.8.5</version>
    <executions>
        <execution>
            <id>report</id>
            <goals>
                <goal>report-aggregate</goal>
            </goals>
            <phase>verify</phase>
        </execution>
    </executions>
</plugin>

As current versions of the jacoco-maven-plugin are compatible with the xml-reports, this will create for every module in it's own target folder a site/jacoco-aggregate folder containing a jacoco.xml file.

To let Sonar combine all the modules, use following command:

mvn -Dsonar.coverage.jacoco.xmlReportPaths=full-path-to-module1/target/site/jacoco-aggregate/jacoco.xml,module2...,module3... clean verify sonar:sonar

To keep my answer short and precise, I did not mention the maven-surefire-plugin and maven-failsafe-plugin dependencies. You can just add them without any other configuration:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.22.2</version>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.22.2</version>
    <executions>
        <execution>
        <id>integration-test</id>
            <goals>
                <goal>integration-test</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Please test this function (split()) on a simple file. I was facing the same issue and found that it was because split() was not written properly (exception handling).

The accepted answer is great. I am making a table that helps in quick comprehension of the topic. The explanation involves a simple variable a as well as an indexed array arr.

If we set

a=apple      # a simple variable
arr=(apple)  # an indexed array with a single element

and then echo the expression in the second column, we would get the result / behavior shown in the third column. The fourth column explains the behavior.

Here's what I ended up using.

I'm very new to AngularJS, so would love to see better / alternative solutions.

angular.module('formComponents', [])
    .directive('formInput', function() {
        return {
            restrict: 'E',
            scope: {},
            link: function(scope, element, attrs)
            {
                var type = attrs.type || 'text';
                var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
                var htmlText = '<div class="control-group">' +
                    '<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
                        '<div class="controls">' +
                        '<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
                        '</div>' +
                    '</div>';
                element.html(htmlText);
            }
        }
    })

Example usage:

<form-input label="Application Name" form-id="appName" required/></form-input>
<form-input type="email" label="Email address" form-id="emailAddress" required/></form-input>
<form-input type="password" label="Password" form-id="password" /></form-input>

$('html, body').animate({scrollTop:1200},'50');

You can do this!

You can also use defaultdict to address this situation. It goes something like this:

from collections import defaultdict

#initialises the dictionary with values as list
aTargetDictionary = defaultdict(list)

for aKey in aSourceDictionary:
    aTargetDictionary[aKey].append(aSourceDictionary[aKey])

You should use an AsyncTask (or other way to perform a network operation on background).

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //create and execute the download task
    MyAsyncTask async = new MyAsyncTask();
    async.execute();

}

private class MyAsyncTask extends AsyncTask<Void, Void, Void>{

    //execute on background (out of the UI thread)
    protected Long doInBackground(URL... urls) {
        DownloadFiles();
    }

}

More info about AsyncTask on Android documentation

Hope it helps.

I've always just selected Export from Eclipse. It builds the war file and includes all necessary files. Providing you created the project as a web project that's all you'll need to do. Eclipse makes it very simple to do.

its

selenium.getTable("tablename".rowNumber.colNumber)

not

selenium.getTable("tablename".colNumber.rowNumber)

Using Dapper.Contrib it is as simple as this:

Insert list:

public int Insert(IEnumerable<YourClass> yourClass)
{
    using (SqlConnection conn = new SqlConnection(ConnectionString))
    {
        conn.Open();
        return conn.Insert(yourClass) ;
    }
}

Insert single:

public int Insert(YourClass yourClass)
{
    using (SqlConnection conn = new SqlConnection(ConnectionString))
    {
        conn.Open();
        return conn.Insert(yourClass) ;
    }
}

Update list:

public bool Update(IEnumerable<YourClass> yourClass)
{
    using (SqlConnection conn = new SqlConnection(ConnectionString))
    {
        conn.Open();
        return conn.Update(yourClass) ;
    }
}

Update single:

public bool Update(YourClass yourClass)
{
    using (SqlConnection conn = new SqlConnection(ConnectionString))
    {
        conn.Open();
        return conn.Update(yourClass) ;
    }
}

I had a very similar issue and I'm not quite sure what you're having a problem with, as your suggested code worked great for me. It immediately (a requirement of yours) triggers the following change code.

$('#selectField').change(function(){
    if($('#selectField').val() == 'N'){
        $('#secondaryInput').hide();
    } else {
        $('#secondaryInput').show();
}
});

Then I take the value from the database (this is used on a form for both new input and editing existing records), set it as the selected value, and add the piece I was missing to trigger the above code, ".change()".

$('#selectField').val(valueFromDatabase).change();

So that if the existing value from the database is 'N', it immediately hides the secondary input field in my form.

Even though I had gcc already installed, I had to run

sudo apt-get install build-essential

to get rid of that error

In terms of code readability while(true) in whatever language I feel makes more sense. In terms of how the computer sees it there really shouldn't be any difference in today's society of very efficient compilers and interpreters.

If there is any performance difference to be had I'm sure the translation to MSIL will optimise away. You could check that if you really wanted to.

TL;DR; Your SQL Server instance is using dynamic ports which is not working. Force SQL Server to use static port # 1433.

Complete Details: First of all this problem is more likely if you've a mix of default and named instance or named instances only(which was my case).

Key concept: Each instance of Microsoft SQL Server installed on a computer uses a different port to listen for incoming connection requests. Default instance of SQL Server uses port # 1433. As you install named instances then they will start using dynamic ports which is decided at the time of start-up of Windows service corresponding to named SQL Server instance.

My code was failing (with error code 40) to connect to the only named SQL Server instance that I had on my VM. You can try below possible solutions:

Solution # 1: Client code trying to connect to SQL Server instance takes help from SQL Server browser service to figure out port number at which your named instance is listening for incoming connections. Make sure SQL browser service is running on your computer.

Solution # 2: Check the port # (in yellow color) your named SQL Server instance is using from SQL Server configuration manager as shown in the snapshot below:

Use that port number explicitly in your connection string or with sqlcmd shown below:

sqlcmd -s mymachinename,11380 -i deleteDB.sql -o SQLDelete.txt

Solution # 3: Force your named instance to use port # 1433 which is used by default instance. Remember this will work only if you don't have any default SQL Server instance on your computer as the default SQL Server instance would be using using port # 1433 already. Same port number can't be uses by two different Windows services.

Mark TCP Dynamic ports field to blank and TCP Port field to 1433.

Change the port number in your connection string as shown below:

sqlcmd -s mymachinename\instanceName -i deleteDB.sql -o SQLDelete.txt

OR

sqlcmd -s mymachinename,1433 -i deleteDB.sql -o SQLDelete.txt

Note: Every change in TCP/IP settings requires corresponding Windows service restart.

Interestingly enough after resolving the error when I went back to dynamic port setting to reproduce the same error then it didn't happen. Not sure why.

Please read below interesting threads to know more about dynamic ports of SQL Server:

Why flush if you can commit?

As someone new to working with databases and sqlalchemy, the previous answers - that flush() sends SQL statements to the DB and commit() persists them - were not clear to me. The definitions make sense but it isn't immediately clear from the definitions why you would use a flush instead of just committing.

Since a commit always flushes (https://docs.sqlalchemy.org/en/13/orm/session_basics.html#committing) these sound really similar. I think the big issue to highlight is that a flush is not permanent and can be undone, whereas a commit is permanent, in the sense that you can't ask the database to undo the last commit (I think)

@snapshoe highlights that if you want to query the database and get results that include newly added objects, you need to have flushed first (or committed, which will flush for you). Perhaps this is useful for some people although I'm not sure why you would want to flush rather than commit (other than the trivial answer that it can be undone).

In another example I was syncing documents between a local DB and a remote server, and if the user decided to cancel, all adds/updates/deletes should be undone (i.e. no partial sync, only a full sync). When updating a single document I've decided to simply delete the old row and add the updated version from the remote server. It turns out that due to the way sqlalchemy is written, order of operations when committing is not guaranteed. This resulted in adding a duplicate version (before attempting to delete the old one), which resulted in the DB failing a unique constraint. To get around this I used flush() so that order was maintained, but I could still undo if later the sync process failed.

See my post on this at: Is there any order for add versus delete when committing in sqlalchemy

Similarly, someone wanted to know whether add order is maintained when committing, i.e. if I add object1 then add object2, does object1 get added to the database before object2 Does SQLAlchemy save order when adding objects to session?

Again, here presumably the use of a flush() would ensure the desired behavior. So in summary, one use for flush is to provide order guarantees (I think), again while still allowing yourself an "undo" option that commit does not provide.

Autoflush and Autocommit

Note, autoflush can be used to ensure queries act on an updated database as sqlalchemy will flush before executing the query. https://docs.sqlalchemy.org/en/13/orm/session_api.html#sqlalchemy.orm.session.Session.params.autoflush

Autocommit is something else that I don't completely understand but it sounds like its use is discouraged: https://docs.sqlalchemy.org/en/13/orm/session_api.html#sqlalchemy.orm.session.Session.params.autocommit

Memory Usage

Now the original question actually wanted to know about the impact of flush vs. commit for memory purposes. As the ability to persist or not is something the database offers (I think), simply flushing should be sufficient to offload to the database - although committing shouldn't hurt (actually probably helps - see below) if you don't care about undoing.

sqlalchemy uses weak referencing for objects that have been flushed: https://docs.sqlalchemy.org/en/13/orm/session_state_management.html#session-referencing-behavior

This means if you don't have an object explicitly held onto somewhere, like in a list or dict, sqlalchemy won't keep it in memory.

However, then you have the database side of things to worry about. Presumably flushing without committing comes with some memory penalty to maintain the transaction. Again, I'm new to this but here's a link that seems to suggest exactly this: https://stackoverflow.com/a/15305650/764365

In other words, commits should reduce memory usage, although presumably there is a trade-off between memory and performance here. In other words, you probably don't want to commit every single database change, one at a time (for performance reasons), but waiting too long will increase memory usage.

I resolve the problem. It's very simple . if do you checking care the problem may be because the auxiliar variable has whitespace. Why ? I don't know but yus must use the trim() method and will resolve the problem

Drag a tooltip control from the toolbox onto your form. You don't really need to give it any properties other than a name. Then, in the properties of the control you wish to have a tooltip on, look for a new property with the name of the tooltip control you just added. It will by default give you a tooltip when the cursor hovers the control.

The technique that the W3C has recommended for do this is called "embedding" and is well described by the three articles here: Embedding Fonts. In my limited experiments, I have found this process error-prone and have had limited success in making it function in a multi-browser environment.

Check out the HTML5 PDF viewer:

http://flexpaper.devaldi.com/demo/

Well one way to do it would be saving the base method and then calling it from the overriden method, like so

MyClass.prototype._do_base = MyClass.prototype.do;
MyClass.prototype.do = function(){  

    if (this.name === 'something'){

        //do something new

    }else{
        return this._do_base();
    }

};

var rotator = function(){
  widget.Rotator.rotate();
  setTimeout(rotator,5000);
};
rotator();

Or:

setInterval(
  function(){ widget.Rotator.rotate() },
  5000
);

Or:

setInterval(
  widget.Rotator.rotate.bind(widget.Rotator),
  5000
);

For the sake of completeness, I would add that SQL uses three-valued logic. The expression:

obsolete = 'N' OR instock = 'Y'

Could produce three distinct results:

| obsolete | instock | saleable |
|----------|---------|----------|
| Y        | Y       | true     |
| Y        | N       | false    |
| Y        | null    | null     |
| N        | Y       | true     |
| N        | N       | true     |
| N        | null    | true     |
| null     | Y       | true     |
| null     | N       | null     |
| null     | null    | null     |

So for example if a product is obsolete but you dont know if product is instock then you dont know if product is saleable. You can write this three-valued logic as follows:

SELECT CASE
           WHEN obsolete = 'N' OR instock = 'Y' THEN 'true'
           WHEN NOT (obsolete = 'N' OR instock = 'Y') THEN 'false'
           ELSE NULL
       END AS saleable

Once you figure out how it works, you can convert three results to two results by deciding the behavior of null. E.g. this would treat null as not saleable:

SELECT CASE
           WHEN obsolete = 'N' OR instock = 'Y' THEN 'true'
           ELSE 'false' -- either false or null
       END AS saleable

The '::' is for static members.

Use

 mediaplayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
 mediaplayer.prepareAsync();
 mediaplayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
      @Override
      public void onPrepared(MediaPlayer mp) {
          mediaplayer.start();
      }
 });

Instructions for Drupal 8 / FontAwesome 5

Create a YOUR_THEME_NAME_HERE.THEME file and place it in your themes directory (ie. your_site_name/themes/your_theme_name)

Paste this into the file, it is PHP code to find the Search Block and change the value to the UNICODE for the FontAwesome icon. You can find other characters at this link https://fontawesome.com/cheatsheet.

<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
  $form['keys']['#attributes']['placeholder'][] = t('Search');
  $form['actions']['submit']['#value'] = html_entity_decode('&#xf002;');
}
?>

Open the CSS file of your theme (ie. your_site_name/themes/your_theme_name/css/styles.css) and then paste this in which will change all input submit text to FontAwesome. Not sure if this will work if you also want to add text in the input button though for just an icon it is fine.

Make sure you import FontAwesome, add this at the top of the CSS file

@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');

then add this in the CSS

input#edit-submit {
    font-family: 'Font Awesome\ 5 Free';
    background-color: transparent;
    border: 0;  
}

FLUSH ALL CACHES AND IT SHOULD WORK FINE

Add Google Font Effects

If you are using Google Web Fonts as well you can add also add effects to the icon (see more here https://developers.google.com/fonts/docs/getting_started#enabling_font_effects_beta). You need to import a Google Web Font including the effect(s) you would like to use first in the CSS so it will be

@import url('https://fonts.googleapis.com/css?family=Open+Sans:400,800&effect=3d-float');
@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');

Then go back to your .THEME file and add the class for the 3D Float Effect so the code will now add a class to the input. There are different effects available. So just choose the effect you like, change the CSS for the font import and the change the value FONT-EFFECT-3D-FLOAT int the code below to font-effect-WHATEVER_EFFECT_HERE. Note effects are still in Beta and don't work in all browsers so read here before you try it https://developers.google.com/fonts/docs/getting_started#enabling_font_effects_beta

<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
  $form['keys']['#attributes']['placeholder'][] = t('Search');
  $form['actions']['submit']['#value'] = html_entity_decode('&#xf002;');
  $form['actions']['submit']['#attributes']['class'][] = 'font-effect-3d-float';
}
?>

In Ubuntu 18.04 the QtCreator examples and API docs missing, This is my way to solve this problem, should apply to almost every Ubuntu release.

For QtCreator and Examples and API Docs:

sudo apt install `apt-cache search 5-examples | grep qt | grep example | awk '{print $1 }' | xargs `

sudo apt install `apt-cache search 5-doc | grep "Qt 5 " | awk '{print $1}' | xargs`

sudo apt-get install build-essential qtcreator qt5-default

If something is also missing, then:

sudo apt install `apt-cache search qt | grep 5- | grep ^qt | awk '{print $1}' | xargs `

Hope to be helpful.

A good question. Should tell you it took some time to crack this one. Here is my result.

DECLARE @TABLE TABLE
(  
ID INT,  
USERS VARCHAR(10),  
ACTIVITY VARCHAR(10),  
PAGEURL VARCHAR(10)  
)

INSERT INTO @TABLE  
VALUES  (1, 'Me', 'act1', 'ab'),
        (2, 'Me', 'act1', 'cd'),
        (3, 'You', 'act2', 'xy'),
        (4, 'You', 'act2', 'st')


SELECT T1.USERS, T1.ACTIVITY,   
        STUFF(  
        (  
        SELECT ',' + T2.PAGEURL  
        FROM @TABLE T2  
        WHERE T1.USERS = T2.USERS  
        FOR XML PATH ('')  
        ),1,1,'')  
FROM @TABLE T1  
GROUP BY T1.USERS, T1.ACTIVITY

The actual walk through the directories works as you have coded it. If you replace the contents of the inner loop with a simple print statement you can see that each file is found:

import os
rootdir = 'C:/Users/sid/Desktop/test'

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        print os.path.join(subdir, file)

If you still get errors when running the above, please provide the error message.

Updated for Python3

import os
rootdir = 'C:/Users/sid/Desktop/test'

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        print(os.path.join(subdir, file))

I think you cannot speak of a "conversion" here. That will be a whole project. To "convert" it i think you have to write it again for the iphone.

Have a look at this question:

Is there a multiplatform framework for developing iPhone / Android applications?

As you can see from the answers there, there is no good way of developing applications for both platforms at the same time (except if you're developing games where flash makes it easy to be portable).

Turn out to be some SQL service was stopped somehow on server. Restarting SQL Server service manually was the solution.

I know this is foolish but worked anyway. Thanks @PareshJ for the useful comment.

Benjamin's answer offers a great abstraction for solving this issue, but I was hoping for a less abstracted solution. The explicit way to to resolve this issue is to simply call .catch on the internal promises, and return the error from their callback.

let a = new Promise((res, rej) => res('Resolved!')),
    b = new Promise((res, rej) => rej('Rejected!')),
    c = a.catch(e => { console.log('"a" failed.'); return e; }),
    d = b.catch(e => { console.log('"b" failed.'); return e; });

Promise.all([c, d])
  .then(result => console.log('Then', result)) // Then ["Resolved!", "Rejected!"]
  .catch(err => console.log('Catch', err));

Promise.all([a.catch(e => e), b.catch(e => e)])
  .then(result => console.log('Then', result)) // Then ["Resolved!", "Rejected!"]
  .catch(err => console.log('Catch', err));

Taking this one step further, you could write a generic catch handler that looks like this:

const catchHandler = error => ({ payload: error, resolved: false });

then you can do

> Promise.all([a, b].map(promise => promise.catch(catchHandler))
    .then(results => console.log(results))
    .catch(() => console.log('Promise.all failed'))
< [ 'Resolved!',  { payload: Promise, resolved: false } ]

The problem with this is that the caught values will have a different interface than the non-caught values, so to clean this up you might do something like:

const successHandler = result => ({ payload: result, resolved: true });

So now you can do this:

> Promise.all([a, b].map(result => result.then(successHandler).catch(catchHandler))
    .then(results => console.log(results.filter(result => result.resolved))
    .catch(() => console.log('Promise.all failed'))
< [ 'Resolved!' ]

Then to keep it DRY, you get to Benjamin's answer:

const reflect = promise => promise
  .then(successHandler)
  .catch(catchHander)

where it now looks like

> Promise.all([a, b].map(result => result.then(successHandler).catch(catchHandler))
    .then(results => console.log(results.filter(result => result.resolved))
    .catch(() => console.log('Promise.all failed'))
< [ 'Resolved!' ]

The benefits of the second solution are that its abstracted and DRY. The downside is you have more code, and you have to remember to reflect all your promises to make things consistent.

I would characterize my solution as explicit and KISS, but indeed less robust. The interface doesn't guarantee that you know exactly whether the promise succeeded or failed.

For example you might have this:

const a = Promise.resolve(new Error('Not beaking, just bad'));
const b = Promise.reject(new Error('This actually didnt work'));

This won't get caught by a.catch, so

> Promise.all([a, b].map(promise => promise.catch(e => e))
    .then(results => console.log(results))
< [ Error, Error ]

There's no way to tell which one was fatal and which was wasn't. If that's important then you're going to want to enforce and interface that tracks whether it was successful or not (which reflect does).

If you just want to handle errors gracefully, then you can just treat errors as undefined values:

> Promise.all([a.catch(() => undefined), b.catch(() => undefined)])
    .then((results) => console.log('Known values: ', results.filter(x => typeof x !== 'undefined')))
< [ 'Resolved!' ]

In my case, I don't need to know the error or how it failed--I just care whether I have the value or not. I'll let the function that generates the promise worry about logging the specific error.

const apiMethod = () => fetch()
  .catch(error => {
    console.log(error.message);
    throw error;
  });

That way, the rest of the application can ignore its error if it wants, and treat it as an undefined value if it wants.

I want my high level functions to fail safely and not worry about the details on why its dependencies failed, and I also prefer KISS to DRY when I have to make that tradeoff--which is ultimately why I opted to not use reflect.

Starting from Laravel 5.1.26, tagged on 2015-12-02, a useCurrent() modifier has been added:

Schema::table('users', function ($table) {
    $table->timestamp('created')->useCurrent();
});

PR 10962 (followed by commit 15c487fe) leaded to this addition.

You may also want to read issues 3602 and 11518 which are of interest.

Basically, MySQL 5.7 (with default config) requires you to define either a default value or nullable for time fields.

this should do it.

my $dir = "bla/bla/upload";
opendir DIR,$dir;
my @dir = readdir(DIR);
close DIR;
foreach(@dir){
    if (-f $dir . "/" . $_ ){
        print $_,"   : file\n";
    }elsif(-d $dir . "/" . $_){
        print $_,"   : folder\n";
    }else{
        print $_,"   : other\n";
    }
}

Change:

 data: JSON.stringify({ model: source })

To:

 data: {model: JSON.stringify(source)}

And in your controller you do this:

public void PartSourceAPI(string model)
{
       System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();

   var result = js.Deserialize<PartSourceModel>(model);
}

If the url you use in jquery is /api/PartSourceAPI then the controller name must be api and the action(method) should be PartSourceAPI

Illegal XML Tag Name Characters can be encoded using Unicode UCS-2. This works very nicely. I am using it to create XML that gets turned into json (JPath is weak compared to XPath). Notice the handling of spaces, (, ) characters. Unicode UCS-2 Code Chart: http://www.columbia.edu/kermit/ucs2.html

        tag.Name = tag.Name.Replace(" ", "_x005F_x0020_");
        tag.Name = tag.Name.Replace("(", "_x005F_x0028_");
        tag.Name = tag.Name.Replace(")", "_x005F_x0029_");

XML:

  <Internal_x005F_x0020_Chargeback_x005F_x0020_ID>{CHARGEBACKCODE}</Internal_x005F_x0020_Chargeback_x005F_x0020_ID>
  <Bill_x005F_x0020_To>{CHARGEBACKCODE}</Bill_x005F_x0020_To>
  <Operator_x005F_x0020_or_x005F_x0020_Directly_x005F_x0020_Responsible_x005F_x0020_Individual_x005F_x0020__x005F_x0028_DRI_x005F_x0029_>[email protected]</Operator_x005F_x0020_or_x005F_x0020_Directly_x005F_x0020_Responsible_x005F_x0020_Individual_x005F_x0020__x005F_x0028_DRI_x005F_x0029_>

I don't know the answer for XP, but for latter:

%USERPROFILE%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Low and %USERPROFILE%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5 - these are cache locations. Other mentioned %USERPROFILE%\AppData\Local\Microsoft\Windows\Temporary Internet Files but this not a cache in this directory there are just a reflection of files that are stored somewhere else.

But you can enum %USERPROFILE%\AppData\Local\Microsoft\Windows\Temporary Internet Files and get all files you need, but you should be frustrated that file walker do not detect everything that explorer shows.

Also if you use links I gave you may need ExpandEnvironmentStrings from WinAPI.

Short answer:

<style>
    .clickable-div 
    {
         cursor: pointer;
    }
</style>

Longer answer:

It's important to realize that if you're just using <a> tags everything will work as expected. You can click or drag by mistake on a regular <a> link on an iPhone and everything behaves as the user would expect.

I imagine that you have arbitrary HTML that is not clickable - such as a panel containing text and images that cannot be wrapped with <a>. I found out about this problem when I had such a panel that I wanted to be entirely clickable.

<div class='clickable-div' data-href="http://www.stackoverflow.com">

 ... clickable content here (images/text) ...

</div>

To detect a click anywhere within this div I am using jQuery with a data-href html attribute which is shown above (this attribute is invented by myself and is not a standard jQuery or HTML data attribute.)

$(document).on('click', '.clickable-div', function() {

    document.location = $(this).data('href');

});

This will work on your desktop browser but not iPad no matter how much you click.

You may be tempted to change your event handler from click to click touchstart - and this indeed does trigger the event handler. However if the user wants to drag the page up (to scroll) they'll trigger it too - which is a terrible user experience. [you may have noticed this behavior by sneaky banner ads]

The answer is incredibly simple: Just set the css cursor: pointer.

<style>
    .clickable-div 
    {
         cursor: pointer;
    }
</style>

This had the added benefit for desktop users to indicate the area is clickable with a hand icon.

element.GetAttribute("value");

Eventhough if you don't see the "value" attribute in html dom, you will get the field value displayed on the GUI.

Uniform Resource Identifier (URI) is a string of characters used to identify a name or a resource on the Internet

A URI identifies a resource either by location, or a name, or both. A URI has two specializations known as URL and URN.

A Uniform Resource Locator (URL) is a subset of the Uniform Resource Identifier (URI) that specifies where an identified resource is available and the mechanism for retrieving it. A URL defines how the resource can be obtained. It does not have to be HTTP URL (http://), a URL can also be (ftp://) or (smb://).

A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the URN scheme, and does not imply availability of the identified resource. Both URNs (names) and URLs (locators) are URIs, and a particular URI may be both a name and a locator at the same time.

The URNs are part of a larger Internet information architecture which is composed of URNs, URCs and URLs.

bar.html is not a URN. A URN is similar to a person's name, while a URL is like a street address. The URN defines something's identity, while the URL provides a location. Essentially, "what" vs. "where". A URN has to be of this form <URN> ::= "urn:" <NID> ":" <NSS> where <NID> is the Namespace Identifier, and <NSS> is the Namespace Specific String.

To put it differently:

• A URL is a URI that identifies a resource and also provides the means of locating the resource by describing the way to access it
• A URL is a URI
• A URI is not necessarily a URL

I'd say the only thing left to make it 100% clear would be to have an example of an URI that is not an URL. We can use the examples in the RFC3986:

URL: ftp://ftp.is.co.za/rfc/rfc1808.txt
URL: http://www.ietf.org/rfc/rfc2396.txt
URL: ldap://[2001:db8::7]/c=GB?objectClass?one
URL: mailto:[email protected]
URL: news:comp.infosystems.www.servers.unix
URL: telnet://192.0.2.16:80/
URN (not URL): urn:oasis:names:specification:docbook:dtd:xml:4.1.2
URN (not URL): tel:+1-816-555-1212 (?)

Here's the intended way to convert a String to a Date:

String timestamp = "2011-10-02-18.48.05.123";
DateFormat df = new SimpleDateFormat("yyyy-MM-dd-kk.mm.ss.SSS");
Date parsedDate = df.parse(timestamp);

Admittedly, it only has millisecond resolution, but in all services slower than Twitter, that's all you'll need, especially since most machines don't even track down to the actual nanoseconds.

it has changed and its docked to the right bottom of your android studio by default.

if you dont have that you can open it through view -> tool windows -> device file explorer

As of April 2020, my previously-permanent page tokens started expiring sometime between 1 and 12 hours. I started using user tokens with the manage_pages permission to achieve the previous goal (polling a Page's Events). Those tokens appear to be permanent.

I created a python script based on info found in this post, hosted at github.com/k-funk/facebook_permanent_token, to keep track of what params are required, and which methods of obtaining a permanent token are working.

Try this, its working in FF

body,
input,
select,
button {
 font-family: Arial,Helvetica,sans-serif;
 font-size: 14px;
}

JQuery UI already has this, in my example below I included a maxchar attribute to focus on the next focus-able element (input, select, textarea, button and object) if i typed in the max number of characters

HTML:

text 1 <input type="text" value="" id="txt1" maxchar="5" /><br />
text 2 <input type="text" value="" id="txt2" maxchar="5" /><br />
checkbox 1 <input type="checkbox" value="" id="chk1" /><br />
checkbox 2 <input type="checkbox" value="" id="chk2" /><br />
dropdown 1 <select id="dd1" >
    <option value="1">1</option>
    <option value="1">2</option>
</select><br />
dropdown 2 <select id="dd2">
    <option value="1">1</option>
    <option value="1">2</option>
</select>

Javascript:

$(function() {
    var focusables = $(":focusable");   
    focusables.keyup(function(e) {
        var maxchar = false;
        if ($(this).attr("maxchar")) {
            if ($(this).val().length >= $(this).attr("maxchar"))
                maxchar = true;
            }
        if (e.keyCode == 13 || maxchar) {
            var current = focusables.index(this),
                next = focusables.eq(current+1).length ? focusables.eq(current+1) : focusables.eq(0);
            next.focus();
        }
    });
});

The for loop is definitely more pythonic, as it uses Python's higher level built in functionality to convey what you're doing both more clearly and concisely. The overhead of range vs xrange, and assigning an unused i variable, stem from the absence of a statement like Verilog's repeat statement. The main reason to stick to the for range solution is that other ways are more complex. For instance:

from itertools import repeat

for unused in repeat(None, 10):
    del unused   # redundant and inefficient, the name is clear enough
    print "This is run 10 times"

Using repeat instead of range here is less clear because it's not as well known a function, and more complex because you need to import it. The main style guides if you need a reference are PEP 20 - The Zen of Python and PEP 8 - Style Guide for Python Code.

We also note that the for range version is an explicit example used in both the language reference and tutorial, although in that case the value is used. It does mean the form is bound to be more familiar than the while expansion of a C-style for loop.

I tried using disabled along with click event. Below is the snippet , the accepted answer also worked perfectly fine , I am adding this answer to give an example how it can be used with disabled and click properties.

<button (click)="!planNextDisabled && planNext()" [disabled]="planNextDisabled"></button>

Just adding to this that in ES6 because of arrow functions you shouldn't need to do this because they capture the this value.

The quick answer is 2^16 TCP ports, 64K.

The issues with system imposed limits is a configuration issue, already touched upon in previous comments.

The internal implications to TCP is not so clear (to me). Each port requires memory for it's instantiation, goes onto a list and needs network buffers for data in transit.

Given 64K TCP sessions the overhead for instances of the ports might be an issue on a 32-bit kernel, but not a 64-bit kernel (correction here gladly accepted). The lookup process with 64K sessions can slow things a bit and every packet hits the timer queues, which can also be problematic. Storage for in transit data can theoretically swell to the window size times ports (maybe 8 GByte).

The issue with connection speed (mentioned above) is probably what you are seeing. TCP generally takes time to do things. However, it is not required. A TCP connect, transact and disconnect can be done very efficiently (check to see how the TCP sessions are created and closed).

There are systems that pass tens of gigabits per second, so the packet level scaling should be OK.

There are machines with plenty of physical memory, so that looks OK.

The performance of the system, if carefully configured should be OK.

The server side of things should scale in a similar fashion.

I would be concerned about things like memory bandwidth.

Consider an experiment where you login to the local host 10,000 times. Then type a character. The entire stack through user space would be engaged on each character. The active footprint would likely exceed the data cache size. Running through lots of memory can stress the VM system. The cost of context switches could approach a second!

This is discussed in a variety of other threads: https://serverfault.com/questions/69524/im-designing-a-system-to-handle-10000-tcp-connections-per-second-what-problems

class Program
{
    static void Main(string[] args)
    {
        Thread t = new Thread(new ParameterizedThreadStart(ThreadMethod));

        t.Start("My Parameter");
    }

    static void ThreadMethod(object parameter)
    {
        // parameter equals to "My Parameter"
    }
}

If you have a large data frame and need to divide into a variable number of sub data frames rows, like for example each sub dataframe has a max of 4500 rows, this script could help:

max_rows = 4500
dataframes = []
while len(df) > max_rows:
    top = df[:max_rows]
    dataframes.append(top)
    df = df[max_rows:]
else:
    dataframes.append(df)

You could then save out these data frames:

for _, frame in enumerate(dataframes):
    frame.to_csv(str(_)+'.csv', index=False)

Hope this helps someone!

To make matplotlib inline by default in Jupyter (IPython 3):

1. Edit file ~/.ipython/profile_default/ipython_config.py

2. Add line c.InteractiveShellApp.matplotlib = 'inline'

Please note that adding this line to ipython_notebook_config.py would not work. Otherwise it works well with Jupyter and IPython 3.1.0

As David pointed out, I would go with KB in most cases.

php_value post_max_size 2K

Note: my form is simple, just a few text boxes, not long text.

(PHP shorthand for KB is K, as outlined here.)

echo 'junk "Foo Bar" not empty one "" this "but this" and this neither' | sed 's/[^\"]*\"\([^\"]*\)\"[^\"]*/>\1</g'

This will result in: >Foo Bar<><>but this<

Here I showed the result string between ><'s for clarity, also using the non-greedy version with this sed command we first throw out the junk before and after that ""'s and then replace this with the part between the ""'s and surround this by ><'s.

There is a crop() method:

w, h = yourImage.size
yourImage.crop((0, 30, w, h-30)).save(...)

You can use netstat command

netstat --listen

To display open ports and established TCP connections,

netstat -vatn

To display only open UDP ports try the following command:

netstat -vaun

You can use len(list(generator_function()). However, this consumes the generator, but that's the only way you can find out how many elements are generated. So you may want to save the list somewhere if you also want to use the items.

a = list(generator_function())
print(len(a))
print(a[0])

$(this).css('background-color', 'red');

if you are using ajax in your page that require script manager Page.ClientScript
will not work, Try this and it would do the work:

ScriptManager.RegisterClientScriptBlock(this, GetType(),
            "alertMessage", @"alert('your Message ')", true);

Well first of all there's no such thing as "arrays" in Python, Python uses lists and that does make a difference, I suggest you use NumPy which is a pretty good library for Python and it adds a lot of Matlab-like functionality.You can get started here Numpy for Matlab users

The most "foolproof" way is to check for the availability of URL:

public boolean isURL(String url) {
  try {
     (new java.net.URL(url)).openStream().close();
     return true;
  } catch (Exception ex) { }
  return false;
}

Remove conn.commit from Register.java

In your jsp change action to :<form name="registrationform" action="Register" method="post">

This one is good example for Swift 4 about async:

DispatchQueue.global(qos: .background).async {
    // Background Thread
    DispatchQueue.main.async {
        // Run UI Updates or call completion block
    }
}

The node-mysql library automatically performs escaping when used as you are already doing. See https://github.com/felixge/node-mysql#escaping-query-values
