I'd add that in case of really odd behavior - where you spend a couple of hours saying WTF - try manually deleting the /webapps/yourwebapp/WEB-INF/classes directory. A java source file that was moved to another package will not have its compiled class file deleted - at least in the case of an exploded web-application on TC. This can seriously drive you crazy with unpredictable behavior, especially with an annotated servlet.

I know this question is quite old, but that's what actually worked for me:

git commit --date="10 day ago" -m "Your commit message" 

I use mobile-browser-emulator chrome plug-in which is has iphone device types. It actually uses user-agent and size of device on which based responsive pages are rendered

The word "canonical" is just a synonym for "standard" or "usual". It doesn`t have any Java-specific meaning.

Edit: Answered before OP clarified what he wanted. The following is for an onclick similar to javascripts onclick, not the :active pseudo class.

This can only be achieved with either Javascript or the Checkbox Hack

The checkbox hack essentially gets you to click on a label, that "checks" a checkbox, allowing you to style the label as you wish.

The demo

I found a solution of my own. I know that Andras answer is probably the most consistent with MSTEST, but I didn't feel like refactoring my code.

[TestMethod]
public void OneIsOne()
{
    using (ConsoleRedirector cr = new ConsoleRedirector())
    {
        Assert.IsFalse(cr.ToString().Contains("New text"));
        /* call some method that writes "New text" to stdout */
        Assert.IsTrue(cr.ToString().Contains("New text"));
    }
}

The disposable ConsoleRedirector is defined as:

internal class ConsoleRedirector : IDisposable
{
    private StringWriter _consoleOutput = new StringWriter();
    private TextWriter _originalConsoleOutput;
    public ConsoleRedirector()
    {
        this._originalConsoleOutput = Console.Out;
        Console.SetOut(_consoleOutput);
    }
    public void Dispose()
    {
        Console.SetOut(_originalConsoleOutput);
        Console.Write(this.ToString());
        this._consoleOutput.Dispose();
    }
    public override string ToString()
    {
        return this._consoleOutput.ToString();
    }
}

I guess these days you would do:

import subprocess

subprocess.run(["pwd"], cwd="sub-dir")

Using the sibling selector is the general solution for styling other elements when hovering over a given one, but it works only if the other elements follow the given one in the DOM. What can we do when the other elements should actually be before the hovered one? Say we want to implement a signal bar rating widget like the one below:

This can actually be done easily using the CSS flexbox model, by setting flex-direction to reverse, so that the elements are displayed in the opposite order from the one they're in the DOM. The screenshot above is from such a widget, implemented with pure CSS.

Flexbox is very well supported by 95% of modern browsers.

.rating {_x000D_
  display: flex;_x000D_
  flex-direction: row-reverse;_x000D_
  width: 9rem;_x000D_
}_x000D_
.rating div {_x000D_
  flex: 1;_x000D_
  align-self: flex-end;_x000D_
  background-color: black;_x000D_
  border: 0.1rem solid white;_x000D_
}_x000D_
.rating div:hover {_x000D_
  background-color: lightblue;_x000D_
}_x000D_
.rating div[data-rating="1"] {_x000D_

.rating div[data-rating="2"] {_x000D_

.rating div[data-rating="3"] {_x000D_

.rating div[data-rating="5"] {_x000D_
  height: 1rem;_x000D_

.rating div:hover ~ div {_x000D_

}

<div class="rating">_x000D_

I'm not so thrilled about the InetAddress.getLocalHost().getHostName() solution that you can find so many places on the Internet and indeed also here. That method will get you the hostname as seen from a network perspective. I can see two problems with this:

1. What if the host has multiple network interfaces ? The host may be known on the network by multiple names. The one returned by said method is indeterminate afaik.

2. What if the host is not connected to any network and has no network interfaces ?

All OS'es that I know of have the concept of naming a node/host irrespective of network. Sad that Java cannot return this in an easy way. This would be the environment variable COMPUTERNAME on all versions of Windows and the environment variable HOSTNAME on Unix/Linux/MacOS (or alternatively the output from host command hostname if the HOSTNAME environment variable is not available as is the case in old shells like Bourne and Korn).

I would write a method that would retrieve (depending on OS) those OS vars and only as a last resort use the InetAddress.getLocalHost().getHostName() method. But that's just me.

UPDATE (Unices)

As others have pointed out the HOSTNAME environment variable is typically not available to a Java application on Unix/Linux as it is not exported by default. Hence not a reliable method unless you are in control of the clients. This really sucks. Why isn't there a standard property with this information?

Alas, as far as I can see the only reliable way on Unix/Linux would be to make a JNI call to gethostname() or to use Runtime.exec() to capture the output from the hostname command. I don't particularly like any of these ideas but if anyone has a better idea I'm all ears. (update: I recently came across gethostname4j which seems to be the answer to my prayers).

Long read

I've created a long explanation in another answer on another post. In particular you may want to read it because it attempts to establish some terminology, gives concrete examples of when the InetAddress.getLocalHost().getHostName() solution will fail, and points to the only safe solution that I know of currently, namely gethostname4j.

It's sad that Java doesn't provide a method for obtaining the computername. Vote for JDK-8169296 if you are able to.

You can do this using the size attribute in the select tag. Supposing you have 8 options, then you would do it like:

<select name='courses' multiple="multiple" size='8'>

Save the commands in a .SQL file, ex: ClearTables.sql, say in your C:\temp folder.

Contents of C:\Temp\ClearTables.sql

Delete from TableA;
Delete from TableB;
Delete from TableC;
Delete from TableD;
Delete from TableE;

Then use sqlcmd to execute it as follows. Since you said the database is remote, use the following syntax (after updating for your server and database instance name).

sqlcmd -S <ComputerName>\<InstanceName> -i C:\Temp\ClearTables.sql

For example, if your remote computer name is SQLSVRBOSTON1 and Database instance name is MyDB1, then the command would be.

sqlcmd -E -S SQLSVRBOSTON1\MyDB1 -i C:\Temp\ClearTables.sql

Also note that -E specifies default authentication. If you have a user name and password to connect, use -U and -P switches.

You will execute all this by opening a CMD command window.

Using a Batch File.

If you want to save it in a batch file and double-click to run it, do it as follows.

Create, and save the ClearTables.bat like so.

echo off
sqlcmd -E -S SQLSVRBOSTON1\MyDB1 -i C:\Temp\ClearTables.sql
set /p delExit=Press the ENTER key to exit...:

Then double-click it to run it. It will execute the commands and wait until you press a key to exit, so you can see the command output.

Yes, you can input multiple items from cin, using exactly the syntax you describe. The result is essentially identical to:

cin >> a;
cin >> b;
cin >> c;

This is due to a technique called "operator chaining".

Each call to operator>>(istream&, T) (where T is some arbitrary type) returns a reference to its first argument. So cin >> a returns cin, which can be used as (cin>>a)>>b and so forth.

Note that each call to operator>>(istream&, T) first consumes all whitespace characters, then as many characters as is required to satisfy the input operation, up to (but not including) the first next whitespace character, invalid character, or EOF.

tf.contrib has moved out of TF starting TF 2.0 alpha.
Take a look at these tf 2.0 release notes https://github.com/tensorflow/tensorflow/releases/tag/v2.0.0-alpha0
You can upgrade your TF 1.x code to TF 2.x using the tf_upgrade_v2 script https://www.tensorflow.org/alpha/guide/upgrade

You have two ways to enable it.

First, you can set the absolute path of the php module file in your httpd.conf file like this:

LoadModule php5_module /path/to/mods-available/libphp5.so

Second, you can link the module file to the mods-enabled directory:

ln -s /path/to/mods-available/libphp5.so /path/to/mods-enabled/libphp5.so

you may try this:-

myImgView.setImageDrawable(getResources().getDrawable(R.drawable.image_name));

You could do something this way:

$(document.body).find('*').each(function() {
    if($(this).hasClass('lollypops')){ //class replacing..many ways to do this :)
        $(this).removeClass('lollypops');
        $(this).addClass('marshmellows');
    }
    var tmp = $(this).children().remove(); //removing and saving children to a tmp obj
    var text = $(this).text(); //getting just current node text
    text = text.replace(/lollypops/g, "marshmellows"); //replacing every lollypops occurence with marshmellows
    $(this).text(text); //setting text
    $(this).append(tmp); //re-append 'foundlings'
});

example: http://jsfiddle.net/steweb/MhQZD/

You could explicitly set where you want to tick marks with plt.xticks:

plt.xticks(np.arange(min(x), max(x)+1, 1.0))

For example,

import numpy as np
import matplotlib.pyplot as plt

x = [0,5,9,10,15]
y = [0,1,2,3,4]
plt.plot(x,y)
plt.xticks(np.arange(min(x), max(x)+1, 1.0))
plt.show()

(np.arange was used rather than Python's range function just in case min(x) and max(x) are floats instead of ints.)

The plt.plot (or ax.plot) function will automatically set default x and y limits. If you wish to keep those limits, and just change the stepsize of the tick marks, then you could use ax.get_xlim() to discover what limits Matplotlib has already set.

start, end = ax.get_xlim()
ax.xaxis.set_ticks(np.arange(start, end, stepsize))

The default tick formatter should do a decent job rounding the tick values to a sensible number of significant digits. However, if you wish to have more control over the format, you can define your own formatter. For example,

ax.xaxis.set_major_formatter(ticker.FormatStrFormatter('%0.1f'))

Here's a runnable example:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.ticker as ticker

x = [0,5,9,10,15]
y = [0,1,2,3,4]
fig, ax = plt.subplots()
ax.plot(x,y)
start, end = ax.get_xlim()
ax.xaxis.set_ticks(np.arange(start, end, 0.712123))
ax.xaxis.set_major_formatter(ticker.FormatStrFormatter('%0.1f'))
plt.show()

The docs give a fair indicator of what's required., however requests allow us to skip a few steps:

You only need to install the security package extras (thanks @admdrew for pointing it out)

$ pip install requests[security]

or, install them directly:

$ pip install pyopenssl ndg-httpsclient pyasn1

Requests will then automatically inject pyopenssl into urllib3

If you're on ubuntu, you may run into trouble installing pyopenssl, you'll need these dependencies:

$ apt-get install libffi-dev libssl-dev

You could also use a LEFT JOIN and IS NULL condition:

SELECT 
  mac, 
  creation_date 
FROM 
  logs
    LEFT JOIN consols ON logs.mac = consols.mac
WHERE 
  logs_type_id=11
AND
  consols.mac IS NULL;

An index on the "mac" columns might improve performance.

You can create a master page base without included js and jquery files. Put a content place holder in master page base in head section, then create a nested master page that inherits from this master page base. Now put your includes in a asp:content in nested master page, finally create a content page from this nested master page

Example:

//in master page base    

<%@  master language="C#" autoeventwireup="true" inherits="MasterPage" codebehind="MasterPage.master.cs" %>
<html>
<head id="Head1" runat="server">
    <asp:ContentPlaceHolder runat="server" ID="cphChildHead">
        <!-- Nested Master Page include Codes will sit Here -->
    </asp:ContentPlaceHolder>
</head>
<body>
    <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
    </asp:ContentPlaceHolder>
    <!-- some code here -->
</body>
</html>

//in nested master page :
<%@  master language="C#" masterpagefile="~/MasterPage.master" autoeventwireup="true"
    codebehind="MasterPageLib.master.cs" inherits="sampleNameSpace" %>
<asp:Content ID="headcontent" ContentPlaceHolderID="cphChildHead" runat="server">
    <!-- includes will set here a nested master page -->
    <link href="../CSS/pwt-datepicker.css" rel="stylesheet" type="text/css" />

    <script src="../js/jquery-1.9.0.min.js" type="text/javascript"></script>

    <!-- other includes ;) -->
</asp:Content>
<asp:Content ID="bodyContent" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <asp:ContentPlaceHolder ID="cphChildBody" runat="server" EnableViewState="true">
        <!-- Content page code will sit Here -->
    </asp:ContentPlaceHolder>
</asp:Content>

James Gosling likened designing Java to the following:

"There's this principle about moving, when you move from one apartment to another apartment. An interesting experiment is to pack up your apartment and put everything in boxes, then move into the next apartment and not unpack anything until you need it. So you're making your first meal, and you're pulling something out of a box. Then after a month or so you've used that to pretty much figure out what things in your life you actually need, and then you take the rest of the stuff -- forget how much you like it or how cool it is -- and you just throw it away. It's amazing how that simplifies your life, and you can use that principle in all kinds of design issues: not do things just because they're cool or just because they're interesting."

You can read the context of the quote here

Basically operator overloading is great for a class that models some kind of point, currency or complex number. But after that you start running out of examples fast.

Another factor was the abuse of the feature in C++ by developers overloading operators like '&&', '||', the cast operators and of course 'new'. The complexity resulting from combining this with pass by value and exceptions is well covered in the Exceptional C++ book.

It's the ASCII/UTF code for LF (0A) - Unix-based systems are using it as the newline character, while Windows uses the CR-LF PAIR (OD0A).

Just out of interest, if you want to center two or more divs (so they're side by side in the center), then here's how to do it:

<div style="text-align:center;">
    <div style="border:1px solid #000; display:inline-block;">Div 1</div>
    <div style="border:1px solid red; display:inline-block;">Div 2</div>
</div>   

Not sure about older versions, but in 2016.2 removing the .key file(s) didn't work for me.

I'm using my JetBrains account and used the 'Remove License' button found at the bottom of the registration dialog. You can find this under the Help menu or from the startup dialog via Configure -> Manage License....

I make a (sub)folder named "hide", move the file I don't want committed to there. Then do my commit, ignoring complaint about the missing file. Then move the hidden file from hide back to ./

I know of no downside to this tactic.

I changed this line in devise.rb:

config.sign_out_via = :delete

to

config.sign_out_via = :get

and it started working for me.

With pure javascript you can just call the length on the id of the select box. It will be more faster. Typically with everything native javascript is performing better and better with modern browsers

This can be achieved in javascript by

     var dropdownFilterSite = document.querySelector( '#dropDownId' );  //Similar to jQuery

var length = dropdownFilterSite.length.

With the Material Components Library you can use the MaterialButtonToggleGroup:

        <com.google.android.material.button.MaterialButtonToggleGroup
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:checkedButton="@id/b1"
            app:selectionRequired="true"
            app:singleSelection="true">

            <Button
                style="?attr/materialButtonOutlinedStyle"
                android:id="@+id/b1"
                android:layout_width="0dp"
                android:layout_weight="1"
                android:layout_height="wrap_content"
                android:text="OPT1" />

            <Button
                style="?attr/materialButtonOutlinedStyle"
                android:id="@+id/b2"
                android:layout_width="0dp"
                android:layout_weight="1"
                android:layout_height="wrap_content"
                android:text="OPT2" />

        </com.google.android.material.button.MaterialButtonToggleGroup>

As it has more pixels in height, things like GCRectMake that use coordinates won't work seamlessly between versions, as it happened when we got the Retina.

Well, they do work the same with Retina displays - it's just that 1 unit in the CoreGraphics coordinate system will correspond to 2 physical pixels, but you don't/didn't have to do anything, the logic stayed the same. (Have you actually tried to run one of your non-retina apps on a retina iPhone, ever?)

For the actual question: that's why you shouldn't use explicit CGRectMakes and co... That's why you have stuff like [[UIScreen mainScreen] applicationFrame].

I faced Same issue, the issues was there are some inner classes with the static keyword.After removing the static keyword it started working and also the inner class should implements to Serializable

Issue scenario

class A implements Serializable{ 
  class static B{
  } 
}

Resolved By

class A implements Serializable{ 
      class B implements Serializable{
      } 
    }

The issues are relating to an invalid GOROOT.

I think you installed Go in /usr/local/go.
So change your GOROOT path to the value of /usr/local/go/bin.

It seems that you meant to have your workspace (GOPATH) located at /home/me/go.

This might fix your problem.
Add this to the bottom of your bash profile, located here => $HOME/.profile

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin

Make sure to remove the old references of GOROOT.

Then try installing web.go again.

If that doesn't work, then have Ubuntu install Go for you.

sudo apt-get install golang

Contrary to Mark Novakowski answer, which for some reason has been upvoted by many, yes, it is a valid and satisfiable request.

In fact the standard, as Wrikken pointed out, makes just such an example. In practice, Apache responds to such requests as expected (with a 206 code), and this is exactly what I use to implement progressive download, that is, only get the tail of a long log file which grows in real time with polling.

It's possible but not all that easy, to create a hybrid native/managed assembly in C#. Were you using C++ instead it'd be a lot easier, as the Visual C++ compiler can create hybrid assemblies as easily as anything else.

Unless you have a strict requirement to produce a hybrid assembly, I'd agree with MusiGenesis that this isn't really worth the trouble to do with C#. If you need to do it, perhaps look at moving to C++/CLI instead.

You need to change permissions on the folder bootstrap/css. Your super user may be able to access it but it doesn't mean apache or nginx have access to it, that's why you still need to change the permissions.

Tip: I usually make the apache/nginx's user group owner of that kind of folders and give 775 permission to it.

You can see a complete example using java 8, recursion and streams -> Dijkstra algorithm with java

It should be this way:

h2.myClass looks for h2 with class myClass. But you actually want to apply style for h2 inside .myClass so you can use descendant selector .myClass h2.

h2 {
    color: red;
}

.myClass {
    color: green;
}

.myClass h2 {
    color: blue;
}

Demo

This ref will give you some basic idea about the selectors and have a look at descendant selectors

.forEach already has this ability:

const someArray = [9, 2, 5];
someArray.forEach((value, index) => {
    console.log(index); // 0, 1, 2
    console.log(value); // 9, 2, 5
});

But if you want the abilities of for...of, then you can map the array to the index and value:

for (const { index, value } of someArray.map((value, index) => ({ index, value }))) {
    console.log(index); // 0, 1, 2
    console.log(value); // 9, 2, 5
}

That's a little long, so it may help to put it in a reusable function:

function toEntries<T>(a: T[]) {
    return a.map((value, index) => [index, value] as const);
}

for (const [index, value] of toEntries(someArray)) {
    // ..etc..
}

Iterable Version

This will work when targeting ES3 or ES5 if you compile with the --downlevelIteration compiler option.

function* toEntries<T>(values: T[] | IterableIterator<T>) {
    let index = 0;
    for (const value of values) {
        yield [index, value] as const;
        index++;
    }
}

Array.prototype.entries() - ES6+

If you are able to target ES6+ environments then you can use the .entries() method as outlined in Arnavion's answer.

.NET 2.0 does not use lambda expressions. You need to compile to .NET 3.0 to use them.

I just want to explain it in my own way with a small story that I experienced in one of my projects. First I want to explain Why DAO is important? rather than go to What is DAO? for better understanding.

Why DAO is important?
In my one project of my project, I used Client.class which contains all the basic information of our system users. Where I need client then every time I need to do an ugly query where it is needed. Then I felt that decreases the readability and made a lot of redundant boilerplate code.

Then one of my senior developers introduced a QueryUtils.class where all queries are added using public static access modifier and then I don't need to do query everywhere. Suppose when I needed activated clients then I just call -

QueryUtils.findAllActivatedClients();

In this way, I made some optimizations of my code.

But there was another problem !!!

I felt that the QueryUtils.class was growing very highly. 100+ methods were included in that class which was also very cumbersome to read and use. Because this class contains other queries of another domain models ( For example- products, categories locations, etc ).

Then the superhero Mr. CTO introduced a new solution named DAO which solved the problem finally. I felt DAO is very domain-specific. For example, he created a DAO called ClientDAO.class where all Client.class related queries are found which seems very easy for me to use and maintain. The giant QueryUtils.class was broken down into many other domain-specific DAO for example - ProductsDAO.class, CategoriesDAO.class, etc which made the code more Readable, more Maintainable, more Decoupled.

What is DAO?

It is an object or interface, which made an easy way to access data from the database without writing complex and ugly queries every time in a reusable way.

For the fun of it here's an implementation based on the callback approach:

const char* find(const char* s,
                 const char* e,
                 int (*pred)(char))
{
    while( s != e && !pred(*s) ) ++s;
    return s;
}

void split_on_ws(const char* s,
                 const char* e,
                 void (*callback)(const char*, const char*))
{
    const char* p = s;
    while( s != e ) {
        s = find(s, e, isspace);
        callback(p, s);
        p = s = find(s, e, isnotspace);
    }
}

void handle_word(const char* s, const char* e)
{
    // handle the word that starts at s and ends at e
}

int main()
{
    split_on_ws(some_str, some_str + strlen(some_str), handle_word);
}

I used below function to compare two strings and It is working good.

function CompareUserId (first, second)
{

   var regex = new RegExp('^' + first+ '$', 'i');
   if (regex.test(second)) 
   {
        return true;
   }
   else 
   {
        return false;
   }
   return false;
}

If you have not pushed the code to your remote branch (GitHub/Bitbucket) you can change the commit message on the command line as below.

 git commit --amend -m "Your new message"

If you're working on a specific branch do this:

git commit --amend -m "BRANCH-NAME: new message"

If you've already pushed the code with the wrong message, and you need to be careful when changing the message. That is, after you change the commit message and try pushing it again, you end up with having issues. To make it smooth, follow these steps.

Please read my entire answer before doing it.

git commit --amend -m "BRANCH-NAME : your new message"

git push -f origin BRANCH-NAME                # Not a best practice. Read below why?

Important note: When you use the force push directly you might end up with code issues that other developers are working on the same branch. So to avoid those conflicts, you need to pull the code from your branch before making the force push:

 git commit --amend -m "BRANCH-NAME : your new message"
 git pull origin BRANCH-NAME
 git push -f origin BRANCH-NAME

This is the best practice when changing the commit message, if it was already pushed.

If you really wanted to store it in a column and have it queryable a lot of databases support XML now. If not querying you can store them as comma separated values and parse them out with a function when you need them separated. I agree with everyone else though if you are looking to use a relational database a big part of normalization is the separating of data like that. I am not saying that all data fits a relational database though. You could always look into other types of databases if a lot of your data doesn't fit the model.

If you have your array in scope you can use sizeof to determine its size in bytes and use the division to calculate the number of elements:

#define NUM_OF_ELEMS 10
int arr[NUM_OF_ELEMS];
size_t NumberOfElements = sizeof(arr)/sizeof(arr[0]);

If you receive an array as a function argument or allocate an array in heap you can not determine its size using the sizeof. You'll have to store/pass the size information somehow to be able to use it:

void DoSomethingWithArray(int* arr, int NumOfElems)
{
    for(int i = 0; i < NumOfElems; ++i) {
        arr[i] = /*...*/
    }
}

Actually, it is as simple as setting major and minor separately:

In [9]: plot([23, 456, 676, 89, 906, 34, 2345])
Out[9]: [<matplotlib.lines.Line2D at 0x6112f90>]

In [10]: yscale('log')

In [11]: grid(b=True, which='major', color='b', linestyle='-')

In [12]: grid(b=True, which='minor', color='r', linestyle='--')

The gotcha with minor grids is that you have to have minor tick marks turned on too. In the above code this is done by yscale('log'), but it can also be done with plt.minorticks_on().

You cant combine this to attributes.

But you can put both on one action method but you can encapsulate your logic into a other method and call this method from both actions.

The ActionName Attribute allows to have 2 ActionMethods with the same name.

[HttpGet]
public ActionResult MyMethod()
{
    return MyMethodHandler();
}

[HttpPost]
[ActionName("MyMethod")]
public ActionResult MyMethodPost()
{
    return MyMethodHandler();
}

private ActionResult MyMethodHandler()
{
    // handle the get or post request
    return View("MyMethod");
}

The built-in iter function does specifically that:

for x in iter(YOUR_FN, TERM_VAL):
    ...

E.g. (tested in Py2 and 3):

class Easy:
  X = 0
  @classmethod
  def com(cls):
    cls.X += 1
    return cls.X

for x in iter(Easy.com, 10):
  print(">>>", x)

If you want to give a condition to terminate instead of a value, you always can set an equality, and require that equality to be True.

Make sure you have installed HAXM installer on your SDK Manager.

After you download it and make sure you run the setup located in: {SDK_FOLDER}\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe

Note: in Android Studio, the command "intelhaxm.exe" has been changed to "intelhaxm-android.exe"

If you get the error "VT not supported" during the installation disable Hyper-V on windows features. You can execute this command dism.exe /Online /Disable-Feature:Microsoft-Hyper-V. You will also need "Virtualization Technology" to be enabled on your BIOS

If you want to draw a horizontal line in the axes, you might also try ax.hlines() method. You need to specify y position and xmin and xmax in the data coordinate (i.e, your actual data range in the x-axis). A sample code snippet is:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(1, 21, 200)
y = np.exp(-x)

fig, ax = plt.subplots()
ax.plot(x, y)
ax.hlines(y=0.2, xmin=4, xmax=20, linewidth=2, color='r')

plt.show()

The snippet above will plot a horizontal line in the axes at y=0.2. The horizontal line starts at x=4 and ends at x=20. The generated image is:

I think the reason it doesn't work has something to do with the fact that you have the right position set, but not the left.

If you manually set the left to the current position, it seems to go:

Live example: http://jsfiddle.net/XqqtN/

var left = $('#coolDiv').offset().left;  // Get the calculated left position

$("#coolDiv").css({left:left})  // Set the left to its calculated position
             .animate({"left":"0px"}, "slow");

EDIT:

Appears as though Firefox behaves as expected because its calculated left position is available as the correct value in pixels, whereas Webkit based browsers, and apparently IE, return a value of auto for the left position.

Because auto is not a starting position for an animation, the animation effectively runs from 0 to 0. Not very interesting to watch. :o)

Setting the left position manually before the animate as above fixes the issue.

If you don't like cluttering the landscape with variables, here's a nice version of the same thing that obviates the need for a variable:

$("#coolDiv").css('left', function(){ return $(this).offset().left; })
             .animate({"left":"0px"}, "slow");    ?

Normalize.css is mainly a set of styles, based on what its author thought would look good, and make it look consistent across browsers. Reset basically strips styling from elements so you have more control over the styling of everything.

I use both.

Some styles from Reset, some from Normalize.css. For example, from Normalize.css, there's a style to make sure all input elements have the same font, which doesn't occur (between text inputs and textareas). Reset has no such style, so inputs have different fonts, which is not normally wanted.

So bascially, using the two CSS files does a better job 'Equalizing' everything ;)

You can set custom git aliases using git's config. Here's the syntax:

git config --global alias.<aliasName> "<git command>"

For example, if you need an alias to display a list of files which have merge conflicts, run:

git config --global alias.conflicts "diff --name-only --diff-filter=U"

Now you can use the above command only using "conflicts":

git conflicts
# same as running: git diff --name-only --diff-filter=U

If you're dealing with large datasets (i.e. datasets with a high number of columns), the solution noted above can be manually cumbersome, and requires you to know which columns are numeric a priori.

Try this instead.

char_data <- read.csv(input_filename, stringsAsFactors = F)
num_data <- data.frame(data.matrix(char_data))
numeric_columns <- sapply(num_data,function(x){mean(as.numeric(is.na(x)))<0.5})
final_data <- data.frame(num_data[,numeric_columns], char_data[,!numeric_columns])

The code does the following:

1. Imports your data as character columns.
2. Creates an instance of your data as numeric columns.
3. Identifies which columns from your data are numeric (assuming columns with less than 50% NAs upon converting your data to numeric are indeed numeric).
4. Merging the numeric and character columns into a final dataset.

This essentially automates the import of your .csv file by preserving the data types of the original columns (as character and numeric).

# docker rm $(docker ps -aq)

After that use the command as Nguyen suggested.

Since adjacent string literals are automatically joint into a single string, you can just use the implied line continuation inside parentheses as recommended by PEP 8:

print("Why, hello there wonderful "
      "stackoverflow people!")

Use this instead:

<input id='tea-submit' type='submit' name = 'submit'    value = 'Tea'>
<input id='coffee-submit' type='submit' name = 'submit' value = 'Coffee'>

It's new to SQL 2005 and offers a simplified way to group objects, especially for the purpose of securing the objects in that "group".

The following link offers a more in depth explanation as to what it is, why we would use it:

Understanding the Difference between Owners and Schemas in SQL Server

Two ways come to mind:

• Using a command-line tool like the popular ffmpeg, however you will almost always need an own server (or a very nice server administrator / hosting company) to get that

• Using the "screenshoot" plugin for the LongTail Video player that allows the creation of manual screenshots that are then sent to a server-side script.

However I get an error which doesn't make sense seeing as the column's data type was properly modified?

| Level | Code | Msg | Warn | 12 | Data truncated for column 'incoming_Cid' at row 1

You can often get this message when you are doing something like the following:

REPLACE INTO table2 (SELECT * FROM table1);

Resulted in our case in the following error:

SQL Exception: Data truncated for column 'level' at row 1

The problem turned out to be column misalignment that resulted in a tinyint trying to be stored in a datetime field or vice versa.

If your array of objects are complex like:

$scope.friends = [{ name: John , uuid: 1234}, {name: Joe, uuid, 5678}];

And your current model was set to something like:

$scope.user.friend = {name:John, uuid: 1234};

It helped to use the track by function on uuid (or any unique field), as long as the ng-model="user.friend" also has a uuid:

<select ng-model="user.friend" 
ng-options="friend as friend.name for friend in friends track by friend.uuid"> 
</select>

Two alternatives

1) Ordering the original array with sortInPlace

self.assignments.sortInPlace({ $0.order < $1.order })
self.printAssignments(assignments)

2) Using an alternative array to store the ordered array

var assignmentsO = [Assignment] ()
assignmentsO = self.assignments.sort({ $0.order < $1.order })
self.printAssignments(assignmentsO)

You can wrap jQuery calls inside normal JavaScript code. So, for example:

$(document).ready(function() {
    if (someCondition && someOtherCondition) {
        // Make some jQuery call.
    }
});

Extending @endian 's answer, you could use a thread and call a method to update the TextView. Below is some code I made up on the spot.

java.util.Date noteTS;
String time, date;
TextView tvTime, tvDate;

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

    tvTime = (TextView) findViewById(R.id.tvTime);
    tvDate = (TextView) findViewById(R.id.tvDate);

    Thread t = new Thread() {

        @Override
        public void run() {
            try {
                while (!isInterrupted()) {

    noteTS = Calendar.getInstance().getTime();

    String time = "hh:mm"; // 12:00
    tvTime.setText(DateFormat.format(time, noteTS));

    String date = "dd MMMMM yyyy"; // 01 January 2013
    tvDate.setText(DateFormat.format(date, noteTS));
}

if anyone is interested to see the super simple solution written in Kotlin, check the blogpost I just created. The example in the blogpost is based on creating Sectioned RecyclerView:

https://brona.blog/2020/06/sectioned-recyclerview-in-three-steps/

for(map<string, pair<string,string> >::const_iterator it = myMap.begin();
    it != myMap.end(); ++it)
{
    std::cout << it->first << " " << it->second.first << " " << it->second.second << "\n";
}

In C++11, you don't need to spell out map<string, pair<string,string> >::const_iterator. You can use auto

for(auto it = myMap.cbegin(); it != myMap.cend(); ++it)
{
    std::cout << it->first << " " << it->second.first << " " << it->second.second << "\n";
}

Note the use of cbegin() and cend() functions.

Easier still, you can use the range-based for loop:

for(auto elem : myMap)
{
   std::cout << elem.first << " " << elem.second.first << " " << elem.second.second << "\n";
}

Precision of a number is the number of digits.

Scale of a number is the number of digits after the decimal point.

What is generally implied when setting precision and scale on field definition is that they represent maximum values.

Example, a decimal field defined with precision=5 and scale=2 would allow the following values:

• 123.45 (p=5,s=2)
• 12.34 (p=4,s=2)
• 12345 (p=5,s=0)
• 123.4 (p=4,s=1)
• 0 (p=0,s=0)

The following values are not allowed or would cause a data loss:

• 12.345 (p=5,s=3) => could be truncated into 12.35 (p=4,s=2)
• 1234.56 (p=6,s=2) => could be truncated into 1234.6 (p=5,s=1)
• 123.456 (p=6,s=3) => could be truncated into 123.46 (p=5,s=2)
• 123450 (p=6,s=0) => out of range

Note that the range is generally defined by the precision: |value| < 10^p ...

You can alias the same table to give you the id's you want to insert by (if you are doing a row-by-row update:

UPDATE table1 tab1, table1 tab2 -- alias references the same table
SET 
col1 = 1
,col2 = 2
. . . 
WHERE 
tab1.id = tab2.id;

Additionally, It should seem obvious that you can also update from other tables as well. In this case, the update doubles as a "SELECT" statement, giving you the data from the table you are specifying. You are explicitly stating in your query the update values so, the second table is unaffected.

According to Apache Tomcat 7 JNDI Datasource HOW-TO page there must be a resource configuration in web.xml:

<resource-ref>
  <description>DB Connection</description>
  <res-ref-name>jdbc/TestDB</res-ref-name>
  <res-type>javax.sql.DataSource</res-type>
  <res-auth>Container</res-auth>

That works for me

I had the same problem on my new Windows 10 machine. I had to intall the Windows build tools with npm install -g windows-build-tools. (https://github.com/Microsoft/nodejs-guidelines/blob/master/windows-environment.md#environment-setup-and-configuration)

The simpliest way is to use something like this but note that it may not be that good.

input {
  outline: none;
}

I hope you find this useful.

The flags, or parameters that you can use with IFRAME and OBJECT embeds are documented here; the details about which parameter works with what player are also clearly mentioned:

YouTube Embedded Players and Player Parameters

You will notice that autoplay is supported by all players (AS3, AS2 and HTML5).

Your question will trigger discussion I suppose. The general idea is that it's good to separate behavior and structure. Furthermore, afaik, an inline click handler has to be evalled to 'become' a real javascript function. And it's pretty old fashioned, allbeit that that's a pretty shaky argument. Ah, well, read some about it @quirksmode.org

In order to solve the problem set:

• Preferences (Ctrl + Alt + S)
  • Build, Execution, Deployment
    • Compiler
      • Annotation Processors
        • Enable annotation processing

Make sure you have the Lombok plugin for IntelliJ installed!

• Preferences -> Plugins
• Search for "Lombok Plugin"
• Click Browse repositories...
• Choose Lombok Plugin
• Install
• Restart IntelliJ

You can use T-Regx library, that doesn't need delimiters

pattern('^([0-9]+)$')->match($input);

Splits an array in multiple arrays with a fixed maximum size.

public static <T extends Object> List<T[]> splitArray(T[] array, int max){

  int x = array.length / max;
  int r = (array.length % max); // remainder

  int lower = 0;
  int upper = 0;

  List<T[]> list = new ArrayList<T[]>();

  int i=0;

  for(i=0; i<x; i++){

    upper += max;

    list.add(Arrays.copyOfRange(array, lower, upper));

    lower = upper;
  }

  if(r > 0){

    list.add(Arrays.copyOfRange(array, lower, (lower + r)));

  }

  return list;
}

Example - an Array of 11 shall be splitted into multiple Arrays not exceeding a size of 5:

// create and populate an array
Integer[] arr = new Integer[11];

for(int i=0; i<arr.length; i++){
  arr[i] = i;
}

// split into pieces with a max. size of 5
List<Integer[]> list = ArrayUtil.splitArray(arr, 5);

// check
for(int i=0; i<list.size(); i++){

  System.out.println("Array " + i);

  for(int j=0; j<list.get(i).length; j++){
    System.out.println("  " + list.get(i)[j]);
  }
}

Output:

Array 0
  0
  1
  2
  3
  4
Array 1
  5
  6
  7
  8
  9
Array 2
  10

Access your list elements directly by i. Then you can append to your list:

for i in xrange(len(myarr)):
    if somecond(a[i]):
        myarr.append(newObj())

this should do it in Windows: svn stat | find "M"

"sorted" in iOS 9 & xcode 7.3, swift 2.2 is impossible, change "sorted" to "sort", like this:

let dictionary = ["main course": 10.99, "dessert": 2.99, "salad": 5.99]
let sortedKeysAndValues = Array(dictionary).sort({ $0.0 < $1.0 })
print(sortedKeysAndValues)

//sortedKeysAndValues = ["desert": 2.99, "main course": 10.99, "salad": 5.99]

In Latest Version (v2) works headerLeft:null. you can add in controller's navigationOptions as bellow

static navigationOptions = {
    headerLeft: null,
};

I happened to run into this problem because of an Ant build.

That Ant build took files and applied filterchain expandproperties to it. During this file filtering, my Windows machine's implicit default non-UTF-8 character encoding was used to generate the filtered files - therefore characters outside of its character set could not be mapped correctly.

One solution was to provide Ant with an explicit environment variable for UTF-8. In Cygwin, before launching Ant: export ANT_OPTS="-Dfile.encoding=UTF-8".

I was having the same issue and I solved it doing the following:

1. In Visual Studio, select "Project properties".

2. Select the "Web" Tab.

3. Select "Use Local IIS Web server".

4. Check "Use IIS Express"

suppose that you have a page with this address: http://sub.domain.com/virtualPath/page.htm. use the following in page code to achive those results:

• window.location.host : you'll get sub.domain.com:8080 or sub.domain.com:80
• window.location.hostname : you'll get sub.domain.com
• window.location.protocol : you'll get http:
• window.location.port : you'll get 8080 or 80
• window.location.pathname : you'll get /virtualPath
• window.location.origin : you'll get http://sub.domain.com *****

Update: about the .origin

***** As the ref states, browser compatibility for window.location.origin is not clear. I've checked it in chrome and it returned http://sub.domain.com:port if the port is anything but 80, and http://sub.domain.com if the port is 80.

Special thanks to @torazaburo for mentioning that to me.

before start make sure of installation:

yum install -y xorg-x11-server-Xorg xorg-x11-xauth xorg-x11-apps

1. start xming or cygwin
2. make connection with X11 forwarding (in putty don't forget to set localhost:0.0 for X display location)
3. edit sshd.cong and restart

     cat /etc/ssh/sshd_config | grep X
                             X11Forwarding yes
                             X11DisplayOffset 10
AddressFamily inet

4. Without the X11 forwarding, you are subjected to the X11 SECURITY and then you must: authorize the remote server to make a connection with the local X Server using a method (for instance, the xhost command) set the display environment variable to redirect the output to the X server of your local computer. In this example: 192.168.2.223 is the IP of the server 192.168.2.2 is the IP of the local computer where the x server is installed. localhost can also be used.

blablaco@blablaco01 ~
$ xhost 192.168.2.223
192.168.2.223 being added to access control list

blablaco@blablaco01 ~
$ ssh -l root 192.168.2.223
[email protected] password:
Last login: Sat May 22 18:59:04 2010 from etcetc
[root@oel5u5 ~]# export DISPLAY=192.168.2.2:0.0
[root@oel5u5 ~]# echo $DISPLAY
192.168.2.2:0.0
[root@oel5u5 ~]# xclock&

Then the xclock application must launch.

Check it on putty or mobaxterm and don't check in remote desktop Manager software. Be careful for user that sudo in.

I had very similar errors in the Apache2 log files:

(104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
Premature end of script headers: phpinfo.php

After checking the wrapper scripts and Apache2 settings, I realized that /var/www/ did not have accordant permissions. Thus the FCGId Wrapper scripts could not be read at all.

ls -la /var/www
drwxrws---  5 www-data     www-data     4096 Oct  7 11:17 .

For my scenario chmod -o+rx /var/www was required of course, since the used SuExec users are not member of www-data user group - and they should not be member for security reasons of course.

Check this handy pipe for Angular2: Usage:

1. in the SafePipe code, substitute DomSanitizationService with DomSanitizer

2. provide the SafePipe if your NgModule

3. <div [style.background-image]="'url(' + your_property + ')' | safe: 'style'"></div>

aM Charts are also making WPF Chart controls. Currently they only show off a pie chart, but they are set to provide new ones in short term.

I had this error in my DNN application installed on Windows 2012 R2. It's using some 32 bit dll and only Oracle.DataAccess.dll x32 was working. My solution is:

1. Uninstall old Oracle Client \ ODAC.
2. Install Oracle 11 Client x32.
3. Install Oracle ODAC 12 x64.
4. Check IIS Application Pool (Classic version) has option "Enable 32-Bit Applications" = true.

In MySQL, It should be like this

INSERT INTO this_table_archive (col1, col2, ..., coln)
SELECT col1, col2, ..., coln
FROM this_table
WHERE entry_date < '2011-01-01 00:00:00';

MySQL Documentation

This worked for me:

https://blog.dotkam.com/2007/04/10/mysql-reset-lost-root-password/

Step 1: Stop MySQL daemon if it is currently running

  ps -ef | grep mysql      - checks if mysql/mysqld is one of the running processes.

  pkill mysqld             - kills the daemon, if it is running.

Step 2: Run MySQL safe daemon with skipping grant tables

  mysqld_safe --skip-grant-tables &

  mysql -u root mysql

Step 3: Login to MySQL as root with no password

  mysql -u root mysql

Step 4: Run UPDATE query to reset the root password

  UPDATE user SET password=PASSWORD("value=42") WHERE user="root";
  FLUSH PRIVILEGES;

In MySQL 5.7, the 'password' field was removed, now the field name is 'authentication_string':

  UPDATE user SET authentication_string=PASSWORD("42") WHERE 
  user="root";
  FLUSH PRIVILEGES;

Step 5: Stop MySQL safe daemon

Step 6: Start MySQL daemon

Ecu, if you do myObj.a, then it looks for the property named a of myObj. If you do myObj[a] =b then it looks for the a.valueOf() property of myObj.

As explained by others, there's a time discontinuity there. There are two possible timezone offsets for 1927-12-31 23:54:08 at Asia/Shanghai, but only one offset for 1927-12-31 23:54:07. So, depending on which offset is used, there's either a one second difference or a 5 minutes and 53 seconds difference.

This slight shift of offsets, instead of the usual one-hour daylight savings (summer time) we are used to, obscures the problem a bit.

Note that the 2013a update of the timezone database moved this discontinuity a few seconds earlier, but the effect would still be observable.

The new java.time package on Java 8 let use see this more clearly, and provide tools to handle it. Given:

DateTimeFormatterBuilder dtfb = new DateTimeFormatterBuilder();
dtfb.append(DateTimeFormatter.ISO_LOCAL_DATE);
dtfb.appendLiteral(' ');
dtfb.append(DateTimeFormatter.ISO_LOCAL_TIME);
DateTimeFormatter dtf = dtfb.toFormatter();
ZoneId shanghai = ZoneId.of("Asia/Shanghai");

String str3 = "1927-12-31 23:54:07";  
String str4 = "1927-12-31 23:54:08";  

ZonedDateTime zdt3 = LocalDateTime.parse(str3, dtf).atZone(shanghai);
ZonedDateTime zdt4 = LocalDateTime.parse(str4, dtf).atZone(shanghai);

Duration durationAtEarlierOffset = Duration.between(zdt3.withEarlierOffsetAtOverlap(), zdt4.withEarlierOffsetAtOverlap());

Duration durationAtLaterOffset = Duration.between(zdt3.withLaterOffsetAtOverlap(), zdt4.withLaterOffsetAtOverlap());

Then durationAtEarlierOffset will be one second, while durationAtLaterOffset will be five minutes and 53 seconds.

Also, these two offsets are the same:

// Both have offsets +08:05:52
ZoneOffset zo3Earlier = zdt3.withEarlierOffsetAtOverlap().getOffset();
ZoneOffset zo3Later = zdt3.withLaterOffsetAtOverlap().getOffset();

But these two are different:

// +08:05:52
ZoneOffset zo4Earlier = zdt4.withEarlierOffsetAtOverlap().getOffset();

// +08:00
ZoneOffset zo4Later = zdt4.withLaterOffsetAtOverlap().getOffset();

You can see the same problem comparing 1927-12-31 23:59:59 with 1928-01-01 00:00:00, though, in this case, it is the earlier offset that produces the longer divergence, and it is the earlier date that has two possible offsets.

Another way to approach this is to check whether there's a transition going on. We can do this like this:

// Null
ZoneOffsetTransition zot3 = shanghai.getRules().getTransition(ld3.toLocalDateTime);

// An overlap transition
ZoneOffsetTransition zot4 = shanghai.getRules().getTransition(ld3.toLocalDateTime);

You can check whether the transition is an overlap where there's more than one valid offset for that date/time or a gap where that date/time is not valid for that zone id - by using the isOverlap() and isGap() methods on zot4.

I hope this helps people handle this sort of issue once Java 8 becomes widely available, or to those using Java 7 who adopt the JSR 310 backport.

I think the other answers miss one important detail regarding the property name to use in the EL expression. The rules for converting from the method names to property names are specified in 'Introspector.decpitalize` which is part of the java bean standard:

This normally means converting the first character from upper case to lower case, but in the (unusual) special case when there is more than one character and both the first and second characters are upper case, we leave it alone.

Thus "FooBah" becomes "fooBah" and "X" becomes "x", but "URL" stays as "URL".

So in your case the JSTL code should look like the following, note the capital 'P':

<c:if test = "${ansokanInfo.PSystem == 'NAT'}">

Very simple you have to just put
\n where ever you want to break line in your string resource.

For example

String s = my string resource have \n line break here;

Why Not Use an Inner Class (Nesting)

class A extends B {
    private class C extends D {
        //Classes A , B , C , D accessible here 
    }
}

You shouldn't launch as an IIS server. check your launch setting, make sure it switched to your project name( change this name in your launchSettings.json file ), not the IIS.

There is a much easier way with Regex.

private string FixString(string str)
{
    return string.IsNullOrEmpty(str) ? str : Regex.Replace(str, "[\\D]", "");
}

(EDIT: As pointed out by the OP, the using a java.net.Authenticator is required too. I'm updating my answer accordingly for the sake of correctness.)

(EDIT#2: As pointed out in another answer, in JDK 8 it's required to remove basic auth scheme from jdk.http.auth.tunneling.disabledSchemes property)

For authentication, use java.net.Authenticator to set proxy's configuration and set the system properties http.proxyUser and http.proxyPassword.

final String authUser = "user";
final String authPassword = "password";
Authenticator.setDefault(
  new Authenticator() {
    @Override
    public PasswordAuthentication getPasswordAuthentication() {
      return new PasswordAuthentication(authUser, authPassword.toCharArray());
    }
  }
);

System.setProperty("http.proxyUser", authUser);
System.setProperty("http.proxyPassword", authPassword);

System.setProperty("jdk.http.auth.tunneling.disabledSchemes", "");

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

Perhaps a more logical method would be to create a file (e.g. test.html), add some content and then try to set it as the index page:

DirectoryIndex test.html

For the most part, the .htaccess rule will override the Apache configuration where working at the directory/file level

It is part of the object literal syntax. The basic format is:

var obj = { field_name: "field value", other_field: 42 };

Then you can access these values with:

obj.field_name; // -> "field value"
obj["field_name"]; // -> "field value"

You can even have functions as values, basically giving you the methods of the object:

obj['func'] = function(a) { return 5 + a;};
obj.func(4);  // -> 9

You can use a form that includes a submit button. Then use jQuery to prevent the default behavior of a form:

$(document).ready(function($) {_x000D_
  $(document).on('submit', '#submit-form', function(event) {_x000D_
    event.preventDefault();_x000D_
  _x000D_
    alert('page did not reload');_x000D_
  });_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>_x000D_
<form id='submit-form'>_x000D_
  <button type='submit'>submit</button>_x000D_
</form>

Argparse code can be longer than actual implementation code!

That's a problem I find with most popular argument parsing options is that if your parameters are only modest, the code to document them becomes disproportionately large to the benefit they provide.

A relative new-comer to the argument parsing scene (I think) is plac.

It makes some acknowledged trade-offs with argparse, but uses inline documentation and wraps simply around main() type function function:

def main(excel_file_path: "Path to input training file.",
     excel_sheet_name:"Name of the excel sheet containing training data including columns 'Label' and 'Description'.",
     existing_model_path: "Path to an existing model to refine."=None,
     batch_size_start: "The smallest size of any minibatch."=10.,
     batch_size_stop:  "The largest size of any minibatch."=250.,
     batch_size_step:  "The step for increase in minibatch size."=1.002,
     batch_test_steps: "Flag.  If True, show minibatch steps."=False):
"Train a Spacy (http://spacy.io/) text classification model with gold document and label data until the model nears convergence (LOSS < 0.5)."

    pass # Implementation code goes here!

if __name__ == '__main__':
    import plac; plac.call(main)

Here is a tutorial from Google about mapping your App on custom domain: https://cloud.google.com/appengine/docs/domain?hl=FR

It should be the latest update. But please note these 2 things:

1- You may not find you App in the new developer console, then the only workaround for that is download your source code, create a new app from the new developer console and deploy it.

2- You find your App on the developer console, but under the Compute menu you may not find the App Engine Settings as mentioned in the tutorial, then you have to proceed the same as i explained in the first point (create another application)

I hope this helps !

This is the best way which worked for me Execute this Command:-

$(dirname $(readlink $(which javac)))/java_home

I just made a pure Javascript function based on that code. Javascript only version demo: http://jsbin.com/copidifiji

That is the independent code from jQuery

if (window.addEventListener) {window.addEventListener('DOMMouseScroll', wheel, false); 
window.onmousewheel = document.onmousewheel = wheel;}

function wheel(event) {
    var delta = 0;
    if (event.wheelDelta) delta = (event.wheelDelta)/120 ;
    else if (event.detail) delta = -(event.detail)/3;

    handle(delta);
    if (event.preventDefault) event.preventDefault();
    event.returnValue = false;
}

function handle(sentido) {
    var inicial = document.body.scrollTop;
    var time = 1000;
    var distance = 200;
  animate({
    delay: 0,
    duration: time,
    delta: function(p) {return p;},
    step: function(delta) {
window.scrollTo(0, inicial-distance*delta*sentido);   
    }});}

function animate(opts) {
  var start = new Date();
  var id = setInterval(function() {
    var timePassed = new Date() - start;
    var progress = (timePassed / opts.duration);
    if (progress > 1) {progress = 1;}
    var delta = opts.delta(progress);
    opts.step(delta);
    if (progress == 1) {clearInterval(id);}}, opts.delay || 10);
}

You can use LIKE instead of =. Without any wildcards this will have the same effect.

DECLARE @Village TABLE
        (CastleType TEXT)

INSERT INTO @Village
VALUES
  (
    'foo'
  )

SELECT *
FROM   @Village
WHERE  [CastleType] LIKE 'foo' 

text is deprecated. Changing to varchar(max) will be easier to work with.

Also how large is the data likely to be? If you are going to be doing equality comparisons you will ideally want to index this column. This isn't possible if you declare the column as anything wider than 900 bytes though you can add a computed checksum or hash column that can be used to speed this type of query up.

You can also use template matching to detect shapes inside an image.

After yum install python3-pip, check the name of the installed binary. e.g.

ll /usr/bin/pip*

On my CentOS 7, it is named as pip-3 instead of pip3.

In a browser with fetch (basically all of them now):

At the moment, we can't import files with a JSON mime type, only files with a JavaScript mime type. It might be a feature added in the future (official discussion).

fetch('./file.json')
  .then(response => response.json())
  .then(obj => console.log(obj))

In Node.js v13.2+:

It currently requires the --experimental-json-modules flag, otherwise it isn't supported by default.

Try running

node --input-type module --experimental-json-modules --eval "import obj from './file.json'; console.log(obj)"

and see the obj content outputted to console.

If you use pip version of tensorflow, it means it's already compiled and you are just installing it. Basically you install tensorflow-gpu, but when you download it from repository and trying to build, you should build it with CPU AVX support. If you ignore it, you will get the warning every time when you run on cpu.

i like to use a littly tiny library called class-transformer.

it can handle nested-objects, map strings to date-objects and handle different json-property-names a lot more.

Maybe worth a look.

import { Type, plainToClass, Expose } from "class-transformer";
import 'reflect-metadata';

export class Employee{
    @Expose({ name: "uid" })
    id: number;

    firstname: string;
    lastname: string;
    birthdate: Date;
    maxWorkHours: number;
    department: string;

    @Type(() => Permission)
    permissions: Permission[] = [];
    typeOfEmployee: string;
    note: string;

    @Type(() => Date)
    lastUpdate: Date;
}

export class Permission {
  type : string;
}

let json:string = {
    "uid": 123,
    "department": "<anystring>",
    "typeOfEmployee": "<anystring>",
    "firstname": "<anystring>",

```

Because not all variables are of a serializable nature.

1. Serialization and Deserialization are symmetry processes, if not you can't expect the result to be determined, in most cases, undetermined values are meaningless;
2. Serialization and Deserialization are idempotent, it means you can do serialization as many time as you want, and the result is the same.

So if the Object can exists on memory but not on disk, then the Object can't be serializable, because the machine can't restore the memory map when deserialization. Fro example, you can't serialize a Stream object.

You can not serialize a Connection object, because it's state also dependent on the remote site.

If you want to check if the dialog's open on a particular element you can do this:

if ($('#elem').closest('.ui-dialog').is(':visible')) { 
  // do something
}

Or if you just want to check if the element itself is visible you can do:

if ($('#elem').is(':visible')) { 
  // do something
}

Or...

if ($('#elem:visible').length) { 
  // do something
}

To check if a string variable contains a valid email address, the easiest way is to test it against a regular expression. There is a good discussion of various regex's and their trade-offs at regular-expressions.info.

Here is a relatively simple one that leans on the side of allowing some invalid addresses through: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$

How you can use regular expressions depends on the version of iOS you are using.

iOS 4.x and Later

You can use NSRegularExpression, which allows you to compile and test against a regular expression directly.

iOS 3.x

Does not include the NSRegularExpression class, but does include NSPredicate, which can match against regular expressions.

NSString *emailRegex = ...;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
BOOL isValid = [emailTest evaluateWithObject:checkString];

Read a full article about this approach at cocoawithlove.com.

iOS 2.x

Does not include any regular expression matching in the Cocoa libraries. However, you can easily include RegexKit Lite in your project, which gives you access to the C-level regex APIs included on iOS 2.0.

Remember Running Background, Running continuously are two different tasks.

For long-term background processes, Threads aren't optimal with Android. However, here's the code and do it at your own risk...

Remember Service or Thread will run in the background but our task needs to make trigger (call again and again) to get updates, i.e. once the task is completed we need to recall the function for next update.

Timer (periodic trigger), Alarm (Timebase trigger), Broadcast (Event base Trigger), recursion will awake our functions.

public static boolean isRecursionEnable = true;

void runInBackground() {
    if (!isRecursionEnable)
        // Handle not to start multiple parallel threads
        return;

    // isRecursionEnable = false; when u want to stop
    // on exception on thread make it true again  
    new Thread(new Runnable() {
        @Override
        public void run() {
            // DO your work here
            // get the data
            if (activity_is_not_in_background) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        // update UI
                        runInBackground();
                    }
                });
            } else {
                runInBackground();
            }
        }
    }).start();
}

Using Service: If you launch a Service it will start, It will execute the task, and it will terminate itself. after the task execution. terminated might also be caused by exception, or user killed it manually from settings. START_STICKY (Sticky Service) is the option given by android that service will restart itself if service terminated.

Remember the question difference between multiprocessing and multithreading? Service is a background process (Just like activity without UI), The same way how you launch thread in the activity to avoid load on the main thread (Activity thread), the same way you need to launch threads(or async tasks) on service to avoid load on service.

In a single statement, if you want a run a background continues task, you need to launch a StickyService and run the thread in the service on event base

Here I'm basically wrapping a button in a link. The advantage is that you can post to different action methods in the same form.

<a href="Controller/ActionMethod">
    <input type="button" value="Click Me" />
</a>

Adding parameters:

<a href="Controller/ActionMethod?userName=ted">
    <input type="button" value="Click Me" />
</a>

Adding parameters from a non-enumerated Model:

<a href="Controller/[email protected]">
    <input type="button" value="Click Me" />
</a>

You can do the same for an enumerated Model too. You would just have to reference a single entity first. Happy Coding!

This can be possible in three steps:

1. Convert the string in to character array (ToCharArray)
2. Apply for loop on charater array
3. Then apply string replace function (Replace ("sting you want to replace"," original string"));

Try to use this :

 private void button1_Click(object sender, EventArgs e)
    {

        for (int i = 0; i < chBoxListTables.Items.Count; i++)
            if (chBoxListTables.GetItemCheckState(i) == CheckState.Checked)
            {
               txtBx.text += chBoxListTables.Items[i].ToString() + " \n"; 

            }
    }

You can use .change for what you want

$("input[@name='lom']").change(function(){
    // Do something interesting here
});

as of jQuery 1.3

you no longer need the '@'. Correct way to select is:

$("input[name='lom']")

Incorrect usage.

Input type number it's made to have selectable value via arrows up and down.

So basically you are looking for "width" CSS style.

Input text historically is formatted with monospaced font, so size it's also the width it takes.

Input number it's new and "size" property has no sense at all*. A typical usage:

<input type="number" name="quantity" min="1" max="5">

w3c docs

to fix, add a style:

<input type="number" name="email" style="width: 7em">

EDIT: if you want a range, you have to set type="range" and not ="number"

EDIT2: *size is not an allowed value (so, no sense). Check out official W3C specifications

Note: The size attribute works with the following input types: text, search, tel, url, email, and password.

Tip: To specify the maximum number of characters allowed in the element, use the maxlength attribute.

It's a shorthand for <?php echo $a; ?>.

It's enabled by default since 5.4 regardless of php.ini settings.

The solution is to simply not declare width: 100%.

The default is width: auto, which for block-level elements (such as div), will take the "full space" available anyway (different to how width: 100% does it).

See: http://jsfiddle.net/U7PhY/2/

Just in case it's not already clear from my answer: just don't set a width on the child div.

You might instead be interested in box-sizing: border-box.

if you work on linux OS ,there is a command line file --mimetype:

String mimetype(file){

   //1. run cmd
   Object cmd=Runtime.getRuntime().exec("file --mime-type "+file);

   //2 get output of cmd , then 
    //3. parse mimetype
    if(output){return output.split(":")[1].trim(); }
    return "";
}

Then

mimetype("/home/nyapp.war") //  'application/zip'

mimetype("/var/www/ggg/au.mp3") //  'audio/mp3'

There is a good class that does what you want. It can be downloaded at: http://sourceforge.net/projects/snoopy/

Inner Join

The join that displays only the rows that have a match in both the joined tables is known as inner join. This is default join in the query and view Designer.

Syntax for Inner Join

SELECT t1.column_name,t2.column_name
FROM table_name1 t1
INNER JOIN table_name2 t2
ON t1.column_name=t2.column_name

Cross Join

A cross join that produces Cartesian product of the tables that involved in the join. The size of a Cartesian product is the number of the rows in first table multiplied by the number of rows in the second table.

Syntax for Cross Join

SELECT * FROM table_name1
CROSS JOIN table_name2

Or we can write it in another way also

SELECT * FROM table_name1,table_name2

Now check the query below for Cross join

Example

SELECT * FROM UserDetails
CROSS JOIN OrderDetails

Or

SELECT * FROM UserDetails, OrderDetails

You should have if row[2] != "0". Otherwise it's not checking to see if the string value is equal to 0.

Great question.

Consider the following example (scroller is a UIScrollView):

float offset = 1000;
[super viewDidLoad];
for (int i=0;i<500; i++) {
    UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(i * 100, 50, 95, 100)] autorelease];
    [label setText:[NSString stringWithFormat:@"label %d",i]];
    [self.scroller addSubview:label];
    [self.scroller setContentSize:CGSizeMake(self.view.frame.size.width * 2 + offset, 0)];
    [self.scroller setContentInset:UIEdgeInsetsMake(0, -offset, 0, 0)];
}

The insets are the ONLY way to force your scroller to have a "window" on the content where you want it. I'm still messing with this sample code, but the idea is there: use the insets to get a "window" on your UIScrollView.

So I see many possibilities to achieve this.

string text = "Foobar-test";

1. Regex Match everything till the first "-"

   Match result = Regex.Match(text, @"^.*?(?=-)");
   

   • ^ match from the start of the string
   • .*? match any character (.), zero or more times (*) but as less as possible (?)
   • (?=-) till the next character is a "-" (this is a positive look ahead)

2. Regex Match anything that is not a "-" from the start of the string

   Match result2 = Regex.Match(text, @"^[^-]*");
   

   • [^-]* matches any character that is not a "-" zero or more times

3. Regex Match anything that is not a "-" from the start of the string till a "-"

   Match result21 = Regex.Match(text, @"^([^-]*)-");
   

   Will only match if there is a dash in the string, but the result is then found in capture group 1.

4. Split on "-"

   string[] result3 = text.Split('-');
   

   Result is an Array the part before the first "-" is the first item in the Array

5. Substring till the first "-"

   string result4 = text.Substring(0, text.IndexOf("-"));
   

   Get the substring from text from the start till the first occurrence of "-" (text.IndexOf("-"))

You get then all the results (all the same) with this

Console.WriteLine(result);
Console.WriteLine(result2);
Console.WriteLine(result21.Groups[1]);
Console.WriteLine(result3[0]);
Console.WriteLine(result4);

I would prefer the first method.

You need to think also about the behavior, when there is no dash in the string. The fourth method will throw an exception in that case, because text.IndexOf("-") will be -1. Method 1 and 2.1 will return nothing and method 2 and 3 will return the complete string.

I appreciate this is an old post, but it may be useful for people to know that the Azure Migration Wizard (available on Codeplex - can't link to is as Codeplex is at the moment I'm typing this) will do this easily.

I assume that with interface you mean a C++ class with only pure virtual methods (i.e. without any code), instead with abstract class you mean a C++ class with virtual methods that can be overridden, and some code, but at least one pure virtual method that makes the class not instantiable. e.g.:

class MyInterface
{
public:
  // Empty virtual destructor for proper cleanup
  virtual ~MyInterface() {}

  virtual void Method1() = 0;
  virtual void Method2() = 0;
};


class MyAbstractClass
{
public:
  virtual ~MyAbstractClass();

  virtual void Method1();
  virtual void Method2();
  void Method3();

  virtual void Method4() = 0; // make MyAbstractClass not instantiable
};

In Windows programming, interfaces are fundamental in COM. In fact, a COM component exports only interfaces (i.e. pointers to v-tables, i.e. pointers to set of function pointers). This helps defining an ABI (Application Binary Interface) that makes it possible to e.g. build a COM component in C++ and use it in Visual Basic, or build a COM component in C and use it in C++, or build a COM component with Visual C++ version X and use it with Visual C++ version Y. In other words, with interfaces you have high decoupling between client code and server code.

Moreover, when you want to build DLL's with a C++ object-oriented interface (instead of pure C DLL's), as described in this article, it's better to export interfaces (the "mature approach") instead of C++ classes (this is basically what COM does, but without the burden of COM infrastructure).

I'd use an interface if I want to define a set of rules using which a component can be programmed, without specifying a concrete particular behavior. Classes that implement this interface will provide some concrete behavior themselves.

Instead, I'd use an abstract class when I want to provide some default infrastructure code and behavior, and make it possible to client code to derive from this abstract class, overriding the pure virtual methods with some custom code, and complete this behavior with custom code. Think for example of an infrastructure for an OpenGL application. You can define an abstract class that initializes OpenGL, sets up the window environment, etc. and then you can derive from this class and implement custom code for e.g. the rendering process and handling user input:

// Abstract class for an OpenGL app.
// Creates rendering window, initializes OpenGL; 
// client code must derive from it 
// and implement rendering and user input.
class OpenGLApp
{
public:
  OpenGLApp();
  virtual ~OpenGLApp();
  ...

  // Run the app    
  void Run();


  // <---- This behavior must be implemented by the client ---->

  // Rendering
  virtual void Render() = 0;

  // Handle user input
  // (returns false to quit, true to continue looping)
  virtual bool HandleInput() = 0;

  // <--------------------------------------------------------->


private:
  //
  // Some infrastructure code
  //
  ... 
  void CreateRenderingWindow();
  void CreateOpenGLContext();
  void SwapBuffers();
};


class MyOpenGLDemo : public OpenGLApp
{
public:
  MyOpenGLDemo();
  virtual ~MyOpenGLDemo();

  // Rendering
  virtual void Render();  // implements rendering code

  // Handle user input
  virtual bool HandleInput(); // implements user input handling


  //  ... some other stuff
};

Try this

#/bin/bash

read -p "Enter a word: " word
echo "You entered $word"

No, there is not.

As other people have shown, there are ways to simulate Ruby's behavior. But it is possible to have a type that implements IEnumerable that does not expose an index.

DataTable.Clone() should do the trick.

DataTable newTable = originalTable.Clone();

Use prepared statements. Those keep the data and syntax apart, which removes the need for escaping MySQL data. See e.g. this tutorial.

You can use this command:

$ dpkg -s libgtk2.0-0|grep '^Version'

Local to UTC

DateTime dateTimeNew = new DateTime(date.getTime(),
DateTimeZone.forID("Asia/Calcutta"));
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
simpleDateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
String datetimeString = dateTimeNew.toString("yyyy-MM-dd HH:mm:ss");
long milis = 0;
try {
     milis = simpleDateFormat.parse(datetimeString).getTime();
} catch (ParseException e) {
   e.printStackTrace();
}

I stumbled on this question while trying to do the same thing (I think). Here is how I did it:

df['index_col'] = df.index

You can then sort on the new index column, if you like.

After going through so many links and threads and getting frustrated over and over again, I went to the basics and boom! it helped. I simply did:

npm install

I don't know, but it might help someone :)

I would suggest using MonoDevelop.

It is pretty much explicitly designed for use with Mono, and all set up to develop in C#.

The simplest way to install it on Ubuntu would be to install the monodevelop package in Ubuntu. (link on Mono on ubuntu.com) (However, if you want to install a more recent version, I am not sure which PPA would be appropriate)

However, I would not recommend developing with the WinForms toolkit - I do not expect it to have the same behavior in Windows and Mono (the implementations are pretty different). For an overview of the UI toolkits that work with Mono, you can go to the information page on Mono-project.

Here is a slight improvement on the accepted answer that avoids having to use sapply(). Also forces non-first characters to lower.

titleCase <- Vectorize(function(x) {
  
  # Split input vector value
  s <- strsplit(x, " ")[[1]]
  
  # Perform title casing and recombine
  ret <- paste(toupper(substring(s, 1,1)), tolower(substring(s, 2)),
        sep="", collapse=" ")
  
  return(ret)
  
}, USE.NAMES = FALSE)


name <- c("zip CODE", "statE", "final couNt")

titleCase(name)

#> "Zip Code"       "State" "Final Count" 

Wrap it in double quotes

alter user "dell-sys" with password 'Pass@133';

Notice that you will have to use the same case you used when you created the user using double quotes. Say you created "Dell-Sys" then you will have to issue exact the same whenever you refer to that user.

I think the best you do is to drop that user and recreate without illegal identifier characters and without double quotes so you can later refer to it in any case you want.

The set statement doesn't treat spaces the way you expect; your variable is really named Pathname[space] and is equal to [space]C:\Program Files.

Remove the spaces from both sides of the = sign, and put the value in double quotes:

set Pathname="C:\Program Files"

Also, if your command prompt is not open to C:\, then using cd alone can't change drives.

Use

cd /d %Pathname%

or

pushd %Pathname%

instead.

The Way I solved this problem is , Install TCPview go to TCP view and check what ports is Tomcat utilizing there will be few other ports other than 8005,8009,8080 now go to Servers tab in eclipse double click on Tomcatv9.0 server and change port numbers there. This will solve the problem.

You can do it with jQuery UI without another JavaScript library. Just add a function to the .resizable resize event to adjust the width of the other div.

$("#left_pane").resizable({
  handles: 'e', // 'East' side of div draggable
  resize: function() {
    $("#right_pane").outerWidth( $("#container").innerWidth() - $("#left_pane").outerWidth() );
  }
});

Here's the complete JSFiddle.

In the second version, you're passing the String returned from this.id. Not the element itself.

So id.value won't give you what you want.

You would need to pass the element with this.

doSomething(this)

then:

function(el){
    var value = el.value;
    ...
}

Note: In some browsers, the second one would work if you did:

window[id].value 

because element IDs are a global property, but this is not safe.

It makes the most sense to just pass the element with this instead of fetching it again with its ID.

And, how about this ...

string[] sizes = new string[] { "105", "101", "102", "103", "90" };

var size = from x in sizes
           orderby x.Length, x
           select x;

foreach (var p in size)
{
    Console.WriteLine(p);
}

Bundling is all about compressing several JavaScript or stylesheets files without any formatting (also referred as minified) into a single file for saving bandwith and number of requests to load a page.

As example you could create your own bundle:

bundles.Add(New ScriptBundle("~/bundles/mybundle").Include(
            "~/Resources/Core/Javascripts/jquery-1.7.1.min.js",
            "~/Resources/Core/Javascripts/jquery-ui-1.8.16.min.js",
            "~/Resources/Core/Javascripts/jquery.validate.min.js",
            "~/Resources/Core/Javascripts/jquery.validate.unobtrusive.min.js",
            "~/Resources/Core/Javascripts/jquery.unobtrusive-ajax.min.js",
            "~/Resources/Core/Javascripts/jquery-ui-timepicker-addon.js"))

And render it like this:

@Scripts.Render("~/bundles/mybundle")

One more advantage of @Scripts.Render("~/bundles/mybundle") over the native <script src="~/bundles/mybundle" /> is that @Scripts.Render() will respect the web.config debug setting:

  <system.web>
    <compilation debug="true|false" />

If debug="true" then it will instead render individual script tags for each source script, without any minification.

For stylesheets you will have to use a StyleBundle and @Styles.Render().

Instead of loading each script or style with a single request (with script or link tags), all files are compressed into a single JavaScript or stylesheet file and loaded together.

Try this, working fine -

$array = json_decode(json_encode($array), true);

just add 'staticmethod' decorator to function and problem is fixed

class foo(object):
    @staticmethod
    def foodo(thing=None, thong='not underwear'):
        print thing if thing else "nothing" 
        print 'a thong is',thong

The thing with compiling two .cpp files at the same time, it doesnt't mean they "know" about eachother. You will have to create a file, the "tells" your File1.cpp, there actually are functions and classes like ClassTwo. This file is called header-file and often doesn't include any executable code. (There are exception, e.g. for inline functions, but forget them at first) They serve a declarative need, just for telling, which functions are available.

When you have your File2.cpp and include it into your File1.cpp, you see a small problem: There is the same code twice: One in the File1.cpp and one in it's origin, File2.cpp.

Therefore you should create a header file, like File1.hpp or File1.h (other names are possible, but this is simply standard). It works like the following:

//File1.cpp

void SomeFunc(char c) //Definition aka Implementation
{
//do some stuff
}

//File1.hpp

void SomeFunc(char c); //Declaration aka Prototype

And for a matter of clean code you might add the following to the top of File1.cpp:

#include "File1.hpp"

And the following, surrounding File1.hpp's code:

#ifndef FILE1.HPP_INCLUDED
#define FILE1.HPP_INCLUDED
//
//All your declarative code
//
#endif

This makes your header-file cleaner, regarding to duplicate code.

DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = db.parse(new ByteArrayInputStream(xmlString.getBytes("UTF-8"))); //remove the parameter UTF-8 if you don't want to specify the Encoding type.

this works well for me even though the XML structure is complex.

And please make sure your xmlString is valid for XML, notice the escape character should be added "\" at the front.

The main problem might not come from the attributes.

dinner = cage.getChicken();
if(dinner == null) dinner = getFreeRangeChicken();

or

if( (dinner = cage.getChicken() ) == null) dinner = getFreeRangeChicken();

The [:-1] removes the last element. Instead of

a[3:-1]

write

a[3:]

You can read up on Python slicing notation here: Explain Python's slice notation

NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.

In order to use php in .html files, you must associate them with your PHP processor in your HTTP server's config file. In Apache, that looks like this:

AddHandler application/x-httpd-php .html

Syntax of waitpid():

pid_t waitpid(pid_t pid, int *status, int options);

The value of pid can be:

• < -1: Wait for any child process whose process group ID is equal to the absolute value of pid.
• -1: Wait for any child process.
• 0: Wait for any child process whose process group ID is equal to that of the calling process.
• > 0: Wait for the child whose process ID is equal to the value of pid.

The value of options is an OR of zero or more of the following constants:

• WNOHANG: Return immediately if no child has exited.
• WUNTRACED: Also return if a child has stopped. Status for traced children which have stopped is provided even if this option is not specified.
• WCONTINUED: Also return if a stopped child has been resumed by delivery of SIGCONT.

For more help, use man waitpid.

After you get the mysql-dev issues corrected, you may need to remove the bad mysql2 install. Look carefully at the messages after $ bundle install. You may need to

rm -rf vendor/cache/
rm -rf ./Zentest

This will clear out the bad mysql2 installation so that a final $ bundle install can create a good one.

More concise than others:

def parseString(string):
    try:
        return int(string)
    except ValueError:
        return string

b = [[parseString(s) for s in clause.split(', ')] for clause in a]

Alternatively if your format is fixed as <string>, <int>, <int>, you can be even more concise:

def parseClause(a,b,c):
    return [a, int(b), int(c)]

b = [parseClause(*clause) for clause in a]

Just like your steps, setting fileencoding should work. However, I'd like to add one "set bomb" to help editor consider the file as UTF8.

$ vim file
:set bomb
:set fileencoding=utf-8
:wq

My understanding is that HEAD points the current branch, while ORIG_HEAD is used to store the previous HEAD before doing "dangerous" operations.

For example git-rebase and git-am record the original tip of branch before they apply any changes.

JDK >= 1.8

I agree with all the answers above. There is also a nice way with Java 8 Streams:

int[] subArr = IntStream.range(startInclusive, endExclusive)
                        .map(i -> src[i])
                        .toArray();

The benefit about this is, it can be useful for many different types of "src" array and helps to improve writing pipeline operations on the stream.

Not particular about this question, but for example, if the source array was double[] and we wanted to take average() of the sub-array:

double avg = IntStream.range(startInclusive, endExclusive)
                    .mapToDouble(index -> src[index])
                    .average()
                    .getAsDouble();

Edit the code to be as follows:

// Upload file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "images/" . "myFile.txt" );

if( $moved ) {
  echo "Successfully uploaded";         
} else {
  echo "Not uploaded because of error #".$_FILES["file"]["error"];
}

It will give you one of the following error code values 1 to 8:

UPLOAD_ERR_INI_SIZE = Value: 1; The uploaded file exceeds the upload_max_filesize directive in php.ini.

UPLOAD_ERR_FORM_SIZE = Value: 2; The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.

UPLOAD_ERR_PARTIAL = Value: 3; The uploaded file was only partially uploaded.

UPLOAD_ERR_NO_FILE = Value: 4; No file was uploaded.

UPLOAD_ERR_NO_TMP_DIR = Value: 6; Missing a temporary folder. Introduced in PHP 5.0.3.

UPLOAD_ERR_CANT_WRITE = Value: 7; Failed to write file to disk. Introduced in PHP 5.1.0.

UPLOAD_ERR_EXTENSION = Value: 8; A PHP extension stopped the file upload. PHP does not provide a way to ascertain which extension caused the file upload to stop; examining the list of loaded extensions with phpinfo() may help.

As far as I can see dependencies have changed between 2.26-b03 and 2.26-b04 (HK2 was moved to from compile to testCompile)... there might be some change in the jersey dependencies that has not been completed yet (or which lead to a bug).

However, right now the simple solution is to stick to an older version :-)

You should be using a Property:

Private _myValue As String
Public Property MyValue As String
    Get
        Return _myValue
    End Get
    Set(value As String)
        _myValue = value
     End Set
End Property

Then use it like so:

MyValue = "Hello"
Console.write(MyValue)

Everyone already answered but just for the latest updates. If you want to know where all the configuration files reside then run this command in the shell

SELECT name, setting FROM pg_settings WHERE category = 'File Locations';

The solution for later versions of Maven is straight-forward. I am on OS X ElCap, 10.11.6 and upgraded to Maven 3.3.9. I had the same problem with error "Could not find ...org.codehaus.plexus...". The link provided here offered the solution in a comment by McKamey - simply delete M2_HOME (unset M2_HOME). Once I tried that, it all worked as expected.

This can be confirmed by visiting the Maven install page: "Add the bin directory of the created directory apache-maven-3.3.9 to the PATH environment variable" -- no mention of M2_HOME or M3_HOME at all.

Here is your code. I'm assuming you're using python 3 based on the your use of print() and input():

import random

def main():
    #random.seed() --> don't need random.seed()

    #Prompts the user to enter the number of tickets they wish to play.

    #python 3 version:
    tickets = int(input("How many lottery tickets do you want?\n"))

    #Creates the dictionaries "winning_numbers" and "guess." Also creates the variable "winnings" for total amount of money won.
    winning_numbers = []
    winnings = 0

    #Generates the winning lotto numbers.
    for i in range(tickets * 5):
        #del winning_numbers[:] what is this line for?
        randNum = random.randint(1,30)
        while randNum in winning_numbers:    
            randNum = random.randint(1,30)
        winning_numbers.append(randNum)

    print(winning_numbers)
    guess = getguess(tickets)
    nummatches = checkmatch(winning_numbers, guess)

    print("Ticket #"+str(i+1)+": The winning combination was",winning_numbers,".You matched",nummatches,"number(s).\n")

    winningRanks = [0, 0, 10, 500, 20000, 1000000]

    winnings = sum(winningRanks[:nummatches + 1])

    print("You won a total of",winnings,"with",tickets,"tickets.\n")


#Gets the guess from the user.
def getguess(tickets):
    guess = []
    for i in range(tickets):
        bubble = [int(i) for i in input("What numbers do you want to choose for ticket #"+str(i+1)+"?\n").split()]
        guess.extend(bubble)
        print(bubble)
    return guess

#Checks the user's guesses with the winning numbers.
def checkmatch(winning_numbers, guess):
    match = 0
    for i in range(5):
        if guess[i] == winning_numbers[i]:
            match += 1
    return match

main()

I was looking for a similar solution, base on what was suggested on this thread, I use the following DateTime.Now.ToString("MM/dd/yyyy hh:mm:ss.fff") , and it work like charm. Note: that .fff are the precision numbers that you wish to capture.

If you don't want to calculate it using java's Calendar you can use Androids Time class It is supposed to be faster but I didn't notice much difference when i switched.

I could not find any pre-defined functions to determine time between 2 dates for an age in Android. There are some nice helper functions to get formatted time between dates in the DateUtils but that's probably not what you want.

For instance if you want random access to noncontiguous data.

p -> [p0, p1, p2, ...]  
p0 -> data1
p1 -> data2

-- in C

T ** p = (T **) malloc(sizeof(T*) * n);
p[0] = (T*) malloc(sizeof(T));
p[1] = (T*) malloc(sizeof(T));

You store a pointer p that points to an array of pointers. Each pointer points to a piece of data.

If sizeof(T) is big it may not be possible to allocate a contiguous block (ie using malloc) of sizeof(T) * n bytes.

I needed a common event handler in which I can show from which button it is called without using switch case... and done like this..

  Private Sub btn_done_clicked(ByVal sender As System.Object, ByVal e As System.EventArgs)

    MsgBox.Show("you have clicked button " & CType(CType(sender,  _
    System.Windows.Forms.Button).Tag, String))

  End Sub

The other answers to this question all miss the key point that in Java, there is one mutex associated with every object. (I'm assuming you know what a mutex or "lock" is.) This is not the case in most programming languages which have the concept of "locks". For example, in Ruby, you have to explicitly create as many Mutex objects as you need.

I think I know why the creators of Java made this choice (although, in my opinion, it was a mistake). The reason has to do with the inclusion of the synchronized keyword. I believe that the creators of Java (naively) thought that by including synchronized methods in the language, it would become easy for people to write correct multithreaded code -- just encapsulate all your shared state in objects, declare the methods that access that state as synchronized, and you're done! But it didn't work out that way...

Anyways, since any class can have synchronized methods, there needs to be one mutex for each object, which the synchronized methods can lock and unlock.

wait and notify both rely on mutexes. Maybe you already understand why this is the case... if not I can add more explanation, but for now, let's just say that both methods need to work on a mutex. Each Java object has a mutex, so it makes sense that wait and notify can be called on any Java object. Which means that they need to be declared as methods of Object.

Another option would have been to put static methods on Thread or something, which would take any Object as an argument. That would have been much less confusing to new Java programmers. But they didn't do it that way. It's much too late to change any of these decisions; too bad!

You create the relationships the other way around; add foreign keys to the Person type to create a Many-to-One relationship:

class Person(models.Model):
    name = models.CharField(max_length=50)
    birthday = models.DateField()
    anniversary = models.ForeignKey(
        Anniversary, on_delete=models.CASCADE)
    address = models.ForeignKey(
        Address, on_delete=models.CASCADE)

class Address(models.Model):
    line1 = models.CharField(max_length=150)
    line2 = models.CharField(max_length=150)
    postalcode = models.CharField(max_length=10)
    city = models.CharField(max_length=150)
    country = models.CharField(max_length=150)

class Anniversary(models.Model):
    date = models.DateField()

Any one person can only be connected to one address and one anniversary, but addresses and anniversaries can be referenced from multiple Person entries.

Anniversary and Address objects will be given a reverse, backwards relationship too; by default it'll be called person_set but you can configure a different name if you need to. See Following relationships "backward" in the queries documentation.

Try this one

<input type="text" onkeyup="trackChange(this.value)" id="myInput">
<script>
function trackChange(value) {
    window.open("http://www.google.com/search?output=search&q=" + value)
}
</script>

-Contains is actually a collection operator. It is true if the collection contains the object. It is not limited to strings.

-match and -imatch are regular expression string matchers, and set automatic variables to use with captures.

-like, -ilike are SQL-like matchers.

That happened to me too, because I was trying to get an IEnumerable but the response had a single value. Please try to make sure it's a list of data in your response. The lines I used (for api url get) to solve the problem are like these:

HttpResponseMessage response = await client.GetAsync("api/yourUrl");

if (response.IsSuccessStatusCode)
{
    IEnumerable<RootObject> rootObjects =
        awaitresponse.Content.ReadAsAsync<IEnumerable<RootObject>>();

    foreach (var rootObject in rootObjects)
    {
        Console.WriteLine(
            "{0}\t${1}\t{2}",
            rootObject.Data1, rootObject.Data2, rootObject.Data3);
    }

    Console.ReadLine();
}

Hope It helps.

I prefer using a top-level namespace for the application and sub namespaces for the components.

The way you can use classes from other namespaces is surprisingly very similar to the way in java. You can either use "use NAMESPACE" which is similar to an "import PACKAGE" statement, e.g. use std. Or you specify the package as prefix of the class separated with "::", e.g. std::string. This is similar to "java.lang.String" in Java.

Either encode the needed XML entities or use CDATA.

<arg0>
    <!--Optional:-->
    <parameter1>&lt;test>like this&lt;/test></parameter1>
    <!--Optional:-->
    <parameter2><![CDATA[<test>or like this</test>]]></parameter2>
 </arg0>

With macOS 10.15 and Homebrew 2.1.6 I was getting this error with Python 3.7. I just needed to run:

python3 -m ensurepip

Now python3 -m pip works for me.

You can try reusing your local Maven repository for Gradle:

• Install the jar into your local Maven repository:

  mvn install:install-file -Dfile=utility.jar -DgroupId=com.company -DartifactId=utility -Dversion=0.0.1 -Dpackaging=jar

• Check that you have the jar installed into your ~/.m2/ local Maven repository

• Enable your local Maven repository in your build.gradle file:

  repositories {
    mavenCentral()  
    mavenLocal()  
  }
  
  dependencies {  
    implementation ("com.company:utility:0.0.1")  
  }
  

  • Now you should have the jar enabled for implementation in your project

1. Checkout your branch and count quantity of all your commits.
2. Open git bash and write: git rebase -i HEAD~<quantity of your commits> (i.e. git rebase -i HEAD~5)
3. In opened txt file change pick keyword to squash for all commits, except first commit (which is on the top). For top one change it to reword (which means you will provide a new comment for this commit in the next step) and click SAVE! If in vim, press esc then save by entering wq! and press enter.
4. Provide Comment.
5. Open Git and make "Fetch all" to see new changes.

If you need to handle multiple currencies, various number formats etc. I can recommend autoNumeric. Works a treat. Have been using it successfully for several years now.

A "for loop" in most, if not all, programming languages is a mechanism to run a piece of code more than once.

This code:

for i in range(5):
    print i

can be thought of working like this:

i = 0
print i
i = 1
print i
i = 2
print i
i = 3
print i
i = 4
print i

So you see, what happens is not that i gets the value 0, 1, 2, 3, 4 at the same time, but rather sequentially.

I assume that when you say "call a, it gives only 5", you mean like this:

for i in range(5):
    a=i+1
print a

this will print the last value that a was given. Every time the loop iterates, the statement a=i+1 will overwrite the last value a had with the new value.

Code basically runs sequentially, from top to bottom, and a for loop is a way to make the code go back and something again, with a different value for one of the variables.

I hope this answered your question.

OpenID is about authentication (ie. proving who you are), OAuth is about authorisation (ie. to grant access to functionality/data/etc.. without having to deal with the original authentication).

OAuth could be used in external partner sites to allow access to protected data without them having to re-authenticate a user.

The blog post "OpenID versus OAuth from the user’s perspective" has a simple comparison of the two from the user's perspective and "OAuth-OpenID: You’re Barking Up the Wrong Tree if you Think They’re the Same Thing" has more information about it.

If you have Python 2.6 or newer, use format:

'{0:.3g}'.format(num)

For Python 2.5 or older:

'%.3g'%(num)

Explanation:

{0}tells format to print the first argument -- in this case, num.

Everything after the colon (:) specifies the format_spec.

.3 sets the precision to 3.

g removes insignificant zeros. See http://en.wikipedia.org/wiki/Printf#fprintf

For example:

tests=[(1.00, '1'),
       (1.2, '1.2'),
       (1.23, '1.23'),
       (1.234, '1.23'),
       (1.2345, '1.23')]

for num, answer in tests:
    result = '{0:.3g}'.format(num)
    if result != answer:
        print('Error: {0} --> {1} != {2}'.format(num, result, answer))
        exit()
    else:
        print('{0} --> {1}'.format(num,result))

yields

1.0 --> 1
1.2 --> 1.2
1.23 --> 1.23
1.234 --> 1.23
1.2345 --> 1.23

Using Python 3.6 or newer, you could use f-strings:

In [40]: num = 1.234; f'{num:.3g}'
Out[40]: '1.23'

If you are doing it in eclipse, there are a few quick notes that if you are hovering your mouse over a class in your script, it will show a focus dialogue that says hit f2 for focus.

for computer apps, use ImageIcon. and for the path say,

ImageIcon thisImage = new ImageIcon("images/youpic.png");

specify the folder( images) then seperate with / and add the name of the pic file.

I hope this is helpful. If someone else posted it, I didn't read through. So...yea.. thought reinforcement.

As explained in this thread on the cxf-user mailing list, rather than having the CXFServlet load its own spring context from user-webservice-servlet.xml, you can just load the whole lot into the root context. Rename your existing user-webservice-servlet.xml to some other name (e.g. user-webservice-beans.xml) then change your contextConfigLocation parameter to something like:

<servlet>
  <servlet-name>myservlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>myservlet</servlet-name>
  <url-pattern>*.htm</url-pattern>
</servlet-mapping>

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
    /WEB-INF/applicationContext.xml
    /WEB-INF/user-webservice-beans.xml
  </param-value>
</context-param>

<servlet>
  <servlet-name>user-webservice</servlet-name>
  <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  <load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>user-webservice</servlet-name>
  <url-pattern>/UserService/*</url-pattern>
</servlet-mapping>

Since unpaidMembers is a dictionary it always returns two values when called with .items() - (key, value). You may want to keep your data as a list of tuples [(name, email, lastname), (name, email, lastname)..].

In an lsf environment (interactive or otherwise) if the application exceeds memory utilization beyond some preset threshold by the admins on the queue or the resource request in submit to the queue the processes will be killed so other users don't fall victim to a potential run away. It doesn't always send an email when it does so, depending on how its set up.

One solution in this case is to find a queue with larger resources or define larger resource requirements in the submission.

You may also want to review man ulimit

Although I don't remember ulimit resulting in Killed its been a while since I needed that.

Try setting the models to environment and static. That fix my issue.

Attach error handlers as separate chain elements directly to the execution of the steps:

        // Handle errors for step(1)
step(1).then(null, function() { stepError(1); return $q.reject(); })
.then(function() {
                 // Attach error handler for step(2),
                 // but only if step(2) is actually executed
  return step(2).then(null, function() { stepError(2); return $q.reject(); });
})
.then(function() {
                 // Attach error handler for step(3),
                 // but only if step(3) is actually executed
  return step(3).then(null, function() { stepError(3); return $q.reject(); });
});

or using catch():

       // Handle errors for step(1)
step(1).catch(function() { stepError(1); return $q.reject(); })
.then(function() {
                 // Attach error handler for step(2),
                 // but only if step(2) is actually executed
  return step(2).catch(function() { stepError(2); return $q.reject(); });
})
.then(function() {
                 // Attach error handler for step(3),
                 // but only if step(3) is actually executed
  return step(3).catch(function() { stepError(3); return $q.reject(); });
});

Note: This is basically the same pattern as pluma suggests in his answer but using the OP's naming.
