jQuery's .data() does a couple things but it doesn't add the data to the DOM as an attribute. When using it to grab a data attribute, the first thing it does is create a jQuery data object and sets the object's value to the data attribute. After that, it's essentially decoupled from the data attribute.

Example:

<div data-foo="bar"></div>

If you grabbed the value of the attribute using .data('foo'), it would return "bar" as you would expect. If you then change the attribute using .attr('data-foo', 'blah') and then later use .data('foo') to grab the value, it would return "bar" even though the DOM says data-foo="blah". If you use .data() to set the value, it'll change the value in the jQuery object but not in the DOM.

Basically, .data() is for setting or checking the jQuery object's data value. If you are checking it and it doesn't already have one, it creates the value based on the data attribute that is in the DOM. .attr() is for setting or checking the DOM element's attribute value and will not touch the jQuery data value. If you need them both to change you should use both .data() and .attr(). Otherwise, stick with one or the other.

I tried many scripts but they didn't work for all objects. You can't move clustered objects from one tablespace to another. For that you will have to use expdp, so I will suggest expdp is the best option to move all objects to a different tablespace.

Below is the command:

nohup expdp \"/ as sysdba\" DIRECTORY=test_dir DUMPFILE=users.dmp LOGFILE=users.log TABLESPACES=USERS &

\d is called a character class and will match digits. It is equal to [0-9].

+ matches 1 or more occurrences of the character before.

So \d+ means match 1 or more digits.

How can I get the hover effects when I'm using the mouse, but suppress them when I'm using the touchscreen?

Maybe don't think of it so much as suppressing hover effects for touchscreens, but as adding hover effects for mouse events?

If you want to keep the :hover effects in your CSS you could specify different styles for different media:

@media screen { /* hover styles here */ } 

@media handheld { /* non-hover styles here */ }

Except that unfortunately there are plenty of mobile devices that ignore this and just use the screen rules. Fortunately a lot of newer mobile/tablet browsers do support some fancier media queries:

@media screen and (max-width:800px) { /* non-hover styles here */ }

So even if the "screen" or "handheld" part is ignored the "max-width" will do the trick for you. You could just assume that anything with a screen smaller than 800 pixels must be a tablet or phone, and not use hover effects. For the rare users who are using a mouse on a low resolution device they wouldn't see the hover effects but your site would be fine otherwise.

Further reading on media queries? There are plenty of articles about this online - here is one: http://www.alistapart.com/articles/return-of-the-mobile-stylesheet

If you shift the hover effects out of your CSS and apply them with JavaScript then you could bind specifically to mouse events, and/or again you could just make some assumptions just based on screen size with the worst-case "problem" being that some user who is using a mouse misses out on the hover effects.

If you are not using Proxy and still facing this issue, you should use below answer -

git config --global --unset http.proxy

Simply hit this command, and this will fix the issue.

rapidjson is a C++ JSON parser/generator designed to be fast and small memory footprint.

There is a performance comparison with YAJL and JsonCPP.

Update:

I created an open source project Native JSON benchmark, which evaluates 29 (and increasing) C/C++ JSON libraries, in terms of conformance and performance. This should be an useful reference.

The correct character to use in this case is a full colon (:), not a semicolon (;).

My test result:

with setInputType:

editText.setInputType(InputType.TYPE_NULL);

the soft keyboard disappears, but the cursor will also disappear.

with setShowSoftInputOnFocus:

editText.setShowSoftInputOnFocus(false)

It works as expected.

A beautiful way to implement this is to use the imap function from itertools:

from itertools import imap, tee
import operator

def is_sorted(iterable, compare=operator.le):
  a, b = tee(iterable)
  next(b, None)
  return all(imap(compare, a, b))

This implementation is fast and works on any iterables.

A successful ping on your local network can be trapped using ERRORLEVEL.

@ECHO OFF
PING 10.0.0.123
IF ERRORLEVEL 1 GOTO NOT-THERE
ECHO IP ADDRESS EXISTS
PAUSE
EXIT
:NOT-THERE
ECHO IP ADDRESS NOT NOT EXIST
PAUSE
EXIT

Try the zsh. It supports suffix alias, so you can define X in your .zshrc to be

alias -g X="| cut -d' ' -f2"

then you can do:

cat file X

You can take it one step further and define it for the nth column:

alias -g X2="| cut -d' ' -f2"
alias -g X1="| cut -d' ' -f1"
alias -g X3="| cut -d' ' -f3"

which will output the nth column of file "file". You can do this for grep output or less output, too. This is very handy and a killer feature of the zsh.

You can go one step further and define D to be:

alias -g D="|xargs rm"

Now you can type:

cat file X1 D

to delete all files mentioned in the first column of file "file".

If you know the bash, the zsh is not much of a change except for some new features.

Let'e me give an example:

1. client connect to server, and send 1MB data to server every 1 second.

2. server side accept a connection, and then sleep 20 second, without recv msg from client.So the tcp send buffer in the client side will be full.

Code in client side:

#include <arpa/inet.h>
#include <sys/socket.h>
#include <stdio.h>
#include <errno.h>
#include <fcntl.h>
#include <stdlib.h>
#include <string.h>
#define exit_if(r, ...)                                                                          \
    if (r) {                                                                                     \
        printf(__VA_ARGS__);                                                                     \

    exit_if(flags < 0, "fcntl failed");
    int r = fcntl(fd, F_SETFL, flags | O_NONBLOCK);
    exit_if(r < 0, "fcntl failed");

    addr.sin_port = htons(port);
    addr.sin_addr.s_addr = INADDR_ANY;


    int fd = socket(AF_INET, SOCK_STREAM, 0);
    exit_if(fd<0, "create socket error");

    int ret = connect(fd, (struct sockaddr *) &addr, sizeof(struct sockaddr));
    exit_if(ret<0, "connect to server error");
    setNonBlock(fd);

    printf("connect to server success");

    const int LEN = 1024 * 1000;
    char msg[LEN];  // 1MB data
    memset(msg, 'a', LEN);

    for (int i = 0; i < 1000; ++i) {
        int len = send(fd, msg, LEN, 0);
        printf("send: %d, erron: %d, %s \n", len, errno, strerror(errno));
        sleep(1);
    }

}

int main(){
    test_full_sock_buf_1();

    return 0;
}

Code in server side:

    #include <arpa/inet.h>
    #include <sys/socket.h>

    printf("but now I will sleep 15 second, then exit");
    sleep(15);
}

Start server side, then start client side.

server side may output:

accept a connection from 127.0.0.1:35764
but now I will sleep 15 second, then exit
Process finished with exit code 0

client side may output:

connect to server successsend: 1024000, erron: 0, Success 
send: 1024000, erron: 0, Success 
send: 1024000, erron: 0, Success 
send: 552190, erron: 0, Success 
send: -1, erron: 11, Resource temporarily unavailable

send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 

You can see, as the server side doesn't recv the data from client, so when the client side tcp buffer get full, but you still send data, so you may get Resource temporarily unavailable error.

We need to specify the INITIAL_CONTEXT_FACTORY, PROVIDER_URL, USERNAME, PASSWORD etc. of JNDI to create an InitialContext.

In a standalone application, you can specify that as below

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, 
    "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://ldap.wiz.com:389");
env.put(Context.SECURITY_PRINCIPAL, "joeuser");
env.put(Context.SECURITY_CREDENTIALS, "joepassword");

Context ctx = new InitialContext(env);

But if you are running your code in a Java EE container, these values will be fetched by the container and used to create an InitialContext as below

System.getProperty(Context.PROVIDER_URL);

and

these values will be set while starting the container as JVM arguments. So if you are running the code in a container, the following will work

InitialContext ctx = new InitialContext();

 if( ($_POST) && (!empty($_POST['cover_image'])) )    //verifies  if post exists and cover_image is not empty
    {
    //execute whatever code you want
    }

Try this:

"dependencies" : {
  "name1" : "git://github.com/user/project.git#commit-ish",
  "name2" : "git://github.com/user/project.git#commit-ish"
}

You could also try this, where visionmedia/express is name/repo:

"dependencies" : {
   "express" : "visionmedia/express"
}

Or (if the npm package module exists):

"dependencies" : {
  "name": "*"
}

My understanding is you don't need to install Anaconda again to start using a different version of python. Instead, conda has the ability to separately manage python 2 and 3 environments.

I have just tried to install that extension on my dev server.

First, make sure that the extension is correctly enabled. Your phpinfo() output doesn't seem complete.

If it is indeed installed properly, your phpinfo() should have a section that looks like this:

If you do not get that section in your phpinfo(). Make sure that you are using the right version. There are both non-thread-safe and thread-safe versions of the extension.

Finally, check your extension_dir setting. By default it's this: extension_dir = "ext", for most of the time it works fine, but if it doesn't try: extension_dir = "C:\PHP\ext".

===========================================================================

EDIT given new info:

You are using the wrong function. mssql_connect() is part of the Mssql extension. You are using microsoft's extension, so use sqlsrv_connect(), for the API for the microsoft driver, look at SQLSRV_Help.chm which should be extracted to your ext directory when you extracted the extension.

When my button's FlatStyle is set to system, it looks flat. And when it's set to popup, it only pops up when mouses over. Either is what I want. I want it to look sunken when checked and raised when unchecked and no change while mousing over (the button is really a checkbox but the checkbox's appearance property is set to button).

I end up setting the FlatStyle to flat and wrote a new Paint event handler.

 private void checkbox_paint(object sender, PaintEventArgs e)
        {
            CheckBox myCheckbox = (CheckBox)sender;
            Rectangle borderRectangle = myCheckbox.ClientRectangle;
            if (myCheckbox.Checked)
            {
                ControlPaint.DrawBorder3D(e.Graphics, borderRectangle,
                    Border3DStyle.Sunken);
            }
            else
            {
                ControlPaint.DrawBorder3D(e.Graphics, borderRectangle,
                    Border3DStyle.Raised);
            }
        }

I give a similar answer to this question: C# winforms button with solid border, like 3d Sorry for double posting.

Can someone please tell me how to create a static library from a .cpp and a .hpp file? Do I need to create the .o and the the .a?

Yes.

Create the .o (as per normal):

g++ -c header.cpp

Create the archive:

ar rvs header.a header.o

Test:

g++ test.cpp header.a -o executable_name

Note that it seems a bit pointless to make an archive with just one module in it. You could just as easily have written:

g++ test.cpp header.cpp -o executable_name

Still, I'll give you the benefit of the doubt that your actual use case is a bit more complex, with more modules.

Hope this helps!

tag is a block-level element but tag is inline element.Normally we use span tag to style inside block elements.but you don't need to use span tag to inline style.you have to do is; convert block element to inline element using "display: inline"

This should work:

SELECT * FROM Accounts WHERE Username LIKE '%$query%'

My issue was similar - I had a new table i was creating that ahd to tie in to the identity users. After reading the above answers, realized it had to do with IsdentityUser and the inherited properites. I already had Identity set up as its own Context, so to avoid inherently tying the two together, rather than using the related user table as a true EF property, I set up a non-mapped property with the query to get the related entities. (DataManager is set up to retrieve the current context in which OtherEntity exists.)

    [Table("UserOtherEntity")]
        public partial class UserOtherEntity
        {
            public Guid UserOtherEntityId { get; set; }
            [Required]
            [StringLength(128)]
            public string UserId { get; set; }
            [Required]
            public Guid OtherEntityId { get; set; }
            public virtual OtherEntity OtherEntity { get; set; }
        }

    public partial class UserOtherEntity : DataManager
        {
            public static IEnumerable<OtherEntity> GetOtherEntitiesByUserId(string userId)
            {
                return Connect2Context.UserOtherEntities.Where(ue => ue.UserId == userId).Select(ue => ue.OtherEntity);
            }
        }

public partial class ApplicationUser : IdentityUser
    {
        public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
        {
            // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
            var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
            // Add custom user claims here
            return userIdentity;
        }

        [NotMapped]
        public IEnumerable<OtherEntity> OtherEntities
        {
            get
            {
                return UserOtherEntities.GetOtherEntitiesByUserId(this.Id);
            }
        }
    }

The best way would be just to use a Makefile for your project and ST3 will automatically detect build system for your project. For example. If you press shift + ctrl/cmd +B you will see this:

If this is something you are only going to need to do once, have you considered downloading a demo version of Crystal? There's a 30-day trial version available here: http://www.developers.net/businessobjectsshowcase/view/3154

Of course, if you need to edit these files after the 30 day period is over, you would be better off buying Crystal.

Alternatively, if all you need to do is replace a few static literal words, have you tried doing a search and replace in a text editor? (Don't forget to save the original files somewhere safe first!)

In case if you are using node js, then this could be the possible solution

const express = require("express");
const app = express();
const server = app.listen(8080);
server.keepAliveTimeout = 61 * 1000;

I think you should use python wheels for distribution instead of egg now.

Wheels are the new standard of python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.

This is due a conflict of versions, to solve it, just force an update of your support-annotations version, adding this line on your module: app gradle

implementation ('com.android.support:support-annotations:27.1.1')

Hope this solves your issue ;)

Edit

Almost forgot, you can declare a single extra property (https://docs.gradle.org/current/userguide/writing_build_scripts.html#sec:extra_properties) for the version, go to your project (or your top) gradle file, and declare your support, or just for this example, annotation version var

ext.annotation_version = "27.1.1"

Then in your module gradle replace it with:

implementation ("com.android.support:support-annotations:$annotation_version")

This is very similar to the @emadabel solution, which is a good alternative for doing it, but without the block, or the rootproject prefix.

Typically you must set java.library.path on the JVM's command line:

java -Djava.library.path=/path/to/my/dll -cp /my/classpath/goes/here MainClass

int indexOf(Object o) This method returns the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element.

$.active returns the number of active Ajax requests.

More info here

In your codethis refers to the select element not to the selected option

to refer the selected option you can do this -

$(this).find('option:selected').attr("name");

Use lambda expression:

df[df.apply(lambda x: x['col1'] != x['col2'], axis = 1)]

protocol must be subClass of AnyObject, class

example given below

    protocol NameOfProtocol: class {
   // member of protocol
    }
   class ClassName: UIViewController {
      weak var delegate: NameOfProtocol? 
    }

First, let me fix a little bit your declaration:

List<Map<String, List<String>>> listOfMapOfList = 
    new HashList<Map<String, List<String>>>();

Please pay attention that I used concrete class (HashMap) only once. It is important to use interface where you can to be able to change the implementation later.

Now you want to add element to the list, don't you? But the element is a map, so you have to create it:

Map<String, List<String>> mapOfList = new HashMap<String, List<String>>();

Now you want to populate the map. Fortunately you can use utility that creates lists for you, otherwise you have to create list separately:

mapOfList.put("mykey", Arrays.asList("one", "two", "three"));

OK, now we are ready to add the map into the list:

listOfMapOfList.add(mapOfList);

BUT:

Stop creating complicated collections right now! Think about the future: you will probably have to change the internal map to something else or list to set etc. This will probably cause you to re-write significant parts of your code. Instead define class that contains you data and then add it to one-dimentional collection:

Let's call your class Student (just as example):

public Student {
    private String firstName;
    private String lastName;
    private int studentId;

    private Colectiuon<String> courseworks = Collections.emtpyList();

    //constructors, getters, setters etc
}

Now you can define simple collection:

Collection<Student> students = new ArrayList<Student>();

If in future you want to put your students into map where key is the studentId, do it:

Map<Integer, Student> students = new HashMap<Integer, Student>();

SimpleDateFormat newDateFormat = new SimpleDateFormat("dd/MM/yyyy");
Date myDate = newDateFormat.parse("28/12/2013");
newDateFormat.applyPattern("yyyy/MM/dd")
String myDateString = newDateFormat.format(myDate);

Now MyDate = 2013/12/28

If the project type isn't recognized, preventing one of these import methods from working, then try this. Once you add the generic project, you can then add support for whatever language you require.

Yes, the problem is that there are no commits in "bare". This is a problem with the first commit only, if you create the repos in the order (bare,alice). Try doing:

git push --set-upstream origin master

This would only be required the first time. Afterwards it should work normally.

As Chris Johnsen pointed out, you would not have this problem if your push.default was customized. I like upstream/tracking.

Unsigned integers are far more likely to catch you in a particular trap than are signed integers. The trap comes from the fact that while 1 & 3 above are correct, both types of integers can be assigned a value outside the bounds of what it can "hold" and it will be silently converted.

unsigned int ui = -1;
signed int si = -1;

if (ui < 0) {
    printf("unsigned < 0\n");
}
if (si < 0) {
    printf("signed < 0\n");
}
if (ui == si) {
    printf("%d == %d\n", ui, si);
    printf("%ud == %ud\n", ui, si);
}

When you run this, you'll get the following output even though both values were assigned to -1 and were declared differently.

signed < 0
-1 == -1
4294967295d == 4294967295d

From the @Tgr's comment, there is an online tool : https://codetabs.com/count-loc/count-loc-online.html

I had a similar problem with programmatically setting layout_gravity on buttons in a GridLayout.

The trick was to set gravity on the button layoutParams AFTER the button was added to a parent (GridLayout), otherwise the gravity would be ignored.

grid.addView(button)
((GridLayout.LayoutParams)button.getLayoutParams()).setGravity(int)

Trying cleaning AND rebuilding your project: In Android Studio, open up the Build tab at the top left and try both the Clean and Rebuild options.

The reason is that mysql expecting end of the row symbol in the text file after last specified column, and this symbol is char(10) or '\n'. Depends on operation system where text file created or if you created your text file yourself, it can be other combination (Windows uses '\r\n' (chr(13)+chr(10)) as rows separator). Thus, if you use Windows generated text file, add following suffix to your LOAD command: “ LINES TERMINATED BY '\r\n' ”. Otherwise, check how rows are separated in your text file. On default mysql expecting char(10) as rows separator.

There may be two situations.

1. No build.xml is present in the current directory
2. Your ant configuration file has diffrent name.

Please see and confim the same. In the case one you have to find where your build file is located and in the case 2, You will have to run command ant -f <your build file name>.

To combine revision 3 and 4 into a single revision, you can use git rebase. If you want to remove the changes in revision 3, you need to use the edit command in the interactive rebase mode. If you want to combine the changes into a single revision, use squash.

I have successfully used this squash technique, but have never needed to remove a revision before. The git-rebase documentation under "Splitting commits" should hopefully give you enough of an idea to figure it out. (Or someone else might know).

From the git documentation:

Start it with the oldest commit you want to retain as-is:

git rebase -i <after-this-commit>

An editor will be fired up with all the commits in your current branch (ignoring merge commits), which come after the given commit. You can reorder the commits in this list to your heart's content, and you can remove them. The list looks more or less like this:

pick deadbee The oneline of this commit
pick fa1afe1 The oneline of the next commit
...

The oneline descriptions are purely for your pleasure; git-rebase will not look at them but at the commit names ("deadbee" and "fa1afe1" in this example), so do not delete or edit the names.

By replacing the command "pick" with the command "edit", you can tell git-rebase to stop after applying that commit, so that you can edit the files and/or the commit message, amend the commit, and continue rebasing.

If you want to fold two or more commits into one, replace the command "pick" with "squash" for the second and subsequent commit. If the commits had different authors, it will attribute the squashed commit to the author of the first commit.

As mentioned in other answers ORDER BY 1 orders by the first column.

I came across another example of where you might use it though. We have certain queries which need to be ordered select the same column. You would get a SQL error if ordering by Name in the below.

SELECT Name, Name FROM Segment ORDER BY 1

Correct

You can use strtotime() to achieve this:

$new_time = date("Y-m-d H:i:s", strtotime('+3 hours', strtotime($now))); // $now + 3 hours

Latest version of angular (7.2 +) now has the option to pass additional information using NavigationExtras.

Home component

import {
  Router,
  NavigationExtras
} from '@angular/router';
const navigationExtras: NavigationExtras = {
  state: {
    transd: 'TRANS001',
    workQueue: false,
    services: 10,
    code: '003'
  }
};
this.router.navigate(['newComponent'], navigationExtras);

newComponent

test: string;
constructor(private router: Router) {
  const navigation = this.router.getCurrentNavigation();
  const state = navigation.extras.state as {
    transId: string,
    workQueue: boolean,
    services: number,
    code: string
  };
  this.test = "Transaction Key:" + state.transId + "<br /> Configured:" + state.workQueue + "<br /> Services:" + state.services + "<br /> Code: " + state.code;
}

Output

Hope this would help!

In your example

product.valid?

Is actually a function call and calls a function named valid?. Certain types of "test for condition"/boolean functions have a question mark as part of the function name by convention.

Use double brackets...

if [[ expression ]]

Keeping your code human readable not just machine readable. A lot of devices still can only show 80 characters at a time. Also it makes it easier for people with larger screens to multi-task by being able to set up multiple windows to be side by side.

Readability is also one of the reasons for enforced line indentation.

For me, now in 2018. The only thing that fixed my problem (a white glitchy-flicker line running through an image on hover) was applying this to my link element holding the image element that has transform: scale(1.05)

a {
   -webkit-backface-visibility: hidden;
   backface-visibility: hidden;
   -webkit-transform: translateZ(0) scale(1.0, 1.0);
   transform: translateZ(0) scale(1.0, 1.0);
   -webkit-filter: blur(0);
   filter: blur(0);
}
a > .imageElement {
   transition: transform 3s ease-in-out;
}

<style>
a {
color:      ;
}
</style>

This code changes the color from the default to what is specified in the style. Using a:hover, you can change the color of the text from the default on hover.

You can also use MDIParent-child form. Set the child form's parent as MDI Parent

Eg

child.MdiParent = parentForm;
child.Show();

In this case just 1 form will be shown and the child forms will come inside the parent. Hope this helps

When using VSTS, check your global.json file. I had entered the sdk version as just "2.2" which caused a parse error (but not when building locally). Adding the full version, "2.2.104" solved the problem.

The question is old and the technology has advanced, here is the current state:

JSON Web Token (JWT) is a JSON-based open standard (RFC 7519) for passing claims between parties in web application environment. The tokens are designed to be compact, URL-safe and usable especially in web browser single sign-on (SSO) context.

It is simpler than I thought it would be.

To set the font size of the x-axis ticks:

x_ticks=['x tick 1','x tick 2','x tick 3']
ax.set_xticklabels(x_ticks, rotation=0, fontsize=8)

To do it for the y-axis ticks:

y_ticks=['y tick 1','y tick 2','y tick 3']
ax.set_yticklabels(y_ticks, rotation=0, fontsize=8)

The arguments rotation and fontsize can easily control what I was after.

You can also check out recording macros and seeing what code it gives you, it's a great way to start learning some of the more vanilla functions.

You need to have a look at Same Origin Policy:

In computing, the same origin policy is an important security concept for a number of browser-side programming languages, such as JavaScript. The policy permits scripts running on pages originating from the same site to access each other's methods and properties with no specific restrictions, but prevents access to most methods and properties across pages on different sites.

For you to be able to get data, it has to be:

Same protocol and host

You need to implement JSONP to workaround it.

1) Correct

2) You can think of that one as "read only" list, where you don't care about the type of the items.Could e.g. be used by a method that is returning the length of the list.

3) T, E and U are the same, but people tend to use e.g. T for type, E for Element, V for value and K for key. The method that compiles says that it took an array of a certain type, and returns an array of the same type.

4) You can't mix oranges and apples. You would be able to add an Object to your String list if you could pass a string list to a method that expects object lists. (And not all objects are strings)

It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.

<input id="myFileInput" type="file" accept="image/*;capture=camera">

var myInput = document.getElementById('myFileInput');

function sendPic() {
    var file = myInput.files[0];

    // Send file here either by adding it to a `FormData` object 
    // and sending that via XHR, or by simply passing the file into 
    // the `send` method of an XHR instance.
}

myInput.addEventListener('change', sendPic, false);

We can use both for the same way, and they are only different in the performance.

IQueryable only executes against the database in an efficient way. It means that it creates an entire select query and only gets the related records.

For example, we want to take the top 10 customers whose name start with ‘Nimal’. In this case the select query will be generated as select top 10 * from Customer where name like ‘Nimal%’.

But if we used IEnumerable, the query would be like select * from Customer where name like ‘Nimal%’ and the top ten will be filtered at the C# coding level (it gets all the customer records from the database and passes them into C#).

Go to File -> preferences -> settings.

On the right panel you will see all customized user settings so you can remove the ones you want to reset. On doing so the default settings mentioned in left pane will become active instantly.

Using Visual Studio Code, delete the component folder and see in the Project Explorer(left hand side) the files that colors Red that means the files are affected and produced errors. Open each files and remove the code that uses the component.

When I have org.json.JSONObject in the classpath, I do:

Map<String, Object> stats = ...;
System.out.println(new JSONObject(stats).toString(2));

(this beautifully indents lists, sets and maps which may be nested)

I have tried many of the commands listed above, however none worked, even after setting my path to include the directory where I installed Python.

The command py -3 file.py always works for me, and if I want to run Python 2 code, as long as Python 2 is in my path, just changing the command to py -2 file.py works perfectly.

I am using Windows, so I'm not too sure if this command will work on Linux, or Mac, but it's worth a try.

Encode

public static string Base64Encode(string plainText) {
  var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(plainText);
  return System.Convert.ToBase64String(plainTextBytes);
}

Decode

public static string Base64Decode(string base64EncodedData) {
  var base64EncodedBytes = System.Convert.FromBase64String(base64EncodedData);
  return System.Text.Encoding.UTF8.GetString(base64EncodedBytes);
}

If you want short, human-readable IDs and only need them to be unique per JVM run:

private static long idCounter = 0;

public static synchronized String createID()
{
    return String.valueOf(idCounter++);
}    

Edit: Alternative suggested in the comments - this relies on under-the-hood "magic" for thread safety, but is more scalable and just as safe:

private static AtomicLong idCounter = new AtomicLong();

public static String createID()
{
    return String.valueOf(idCounter.getAndIncrement());
}

I would recommend reviewing this page on How to Write Go Code

It documents both how to structure your project in a go build friendly way, and also how to write tests. Tests do not need to be a cmd using the main package. They can simply be TestX named functions as part of each package, and then go test will discover them.

The structure suggested in that link in your question is a bit outdated, now with the release of Go 1. You no longer would need to place a pkg directory under src. The only 3 spec-related directories are the 3 in the root of your GOPATH: bin, pkg, src . Underneath src, you can simply place your project mypack, and underneath that is all of your .go files including the mypack_test.go

go build will then build into the root level pkg and bin.

So your GOPATH might look like this:

~/projects/
    bin/
    pkg/
    src/
      mypack/
        foo.go
        bar.go
        mypack_test.go

export GOPATH=$HOME/projects

$ go build mypack
$ go test mypack

Update: as of >= Go 1.11, the Module system is now a standard part of the tooling and the GOPATH concept is close to becoming obsolete.

Something likes this

public void testPrintOut() {
    int val1 = 8;
    String val2 = "$951.23";
    String val3 = "$215.92";
    String val4 = "$198,301.22";
    System.out.println(String.format("%03d %7s %7s %11s", val1, val2, val3, val4));

    val1 = 9;
    val2 = "$950.19";
    val3 = "$216.95";
    val4 = "$198,084.26";
    System.out.println(String.format("%03d %7s %7s %11s", val1, val2, val3, val4));
}

Dependency required for jersey restful service and Tomcat is the server. where ${jersey.version} is 2.29.1

    <dependency>
        <groupId>javax.enterprise</groupId>
        <artifactId>cdi-api</artifactId>
        <version>2.0.SP1</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.core</groupId>
        <artifactId>jersey-server</artifactId>
        <version>${jersey.version}</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-servlet</artifactId>
        <version>${jersey.version}</version>

        <artifactId>jersey-hk2</artifactId>
        <version>${jersey.version}</version>
    </dependency>

The basic code will be as follows:

@RequestScoped
@Path("test")
public class RESTEndpoint {

   @GET
   public String getMessage() {

This is overly complicated, Jackson handles lists via its writer methods just as well as it handles regular objects. This should work just fine for you, assuming I have not misunderstood your question:

public void writeListToJsonArray() throws IOException {  
    final List<Event> list = new ArrayList<Event>(2);
    list.add(new Event("a1","a2"));
    list.add(new Event("b1","b2"));

    final ByteArrayOutputStream out = new ByteArrayOutputStream();
    final ObjectMapper mapper = new ObjectMapper();

    mapper.writeValue(out, list);

    final byte[] data = out.toByteArray();
    System.out.println(new String(data));
}

Adding one more possible issue causing this: the formula was wrong because I was using the wrong list separator according to my locale. Using CultureInfo.CurrentCulture.TextInfo.ListSeparator; corrected the issue.

Note that the exception was thrown on the following line of code...

To include any separators between words (like everything except all lower case and upper case letters), we can do:

String mystring = "hi, there,hi Leo";
String[] arr = mystring.split("[^a-zA-Z]+");
for(int i = 0; i < arr.length; i += 1)
{
     System.out.println(arr[i]);
}

Here the regex means that the separators will be anything that is not a upper or lower case letter [^a-zA-Z], in groups of at least one [+].

The meaning of this exception is explained here: https://bz.apache.org/bugzilla/show_bug.cgi?id=27829

Summary: Java dies, Tomcat shut down hook is called, exception is thrown.

So if a firewall prevents the shutdown message from reaching Tomcat, Java will eventually die first (ex during system reboot/shutdown), and the exception will appear.

There are other possibilities.

In my case, my problem had something to do with my initscript (Linux) being incorrectly installed. That implied Java was getting killed by the OS during shutdown/reboot and not as a result of the script. The solution as simple as this:

chkconfig --del initscript
chkconfig --add initscript

Before the fix I had the following in rc.d:

find /etc/rc.d | grep initscript | sort
/etc/rc.d/init.d/initscript
/etc/rc.d/rc2.d/S85initscript
/etc/rc.d/rc3.d/S85initscript
/etc/rc.d/rc4.d/S85initscript
/etc/rc.d/rc5.d/S85initscript

After the fix:

find /etc/rc.d | grep initscript | sort
/etc/rc.d/init.d/initscript
/etc/rc.d/rc0.d/K15initscript
/etc/rc.d/rc1.d/K15initscript
/etc/rc.d/rc2.d/K15initscript
/etc/rc.d/rc3.d/K15initscript
/etc/rc.d/rc4.d/K15initscript
/etc/rc.d/rc5.d/S85initscript
/etc/rc.d/rc6.d/K15initscript

Conclusion: if you get this exception, make sure Tomcat is shutdown properly, not as a result of Java being terminated. Check your firewall, shutdown scripts etc.

Netbeans hints:

You get code completion on $users[0]-> and for $this-> for an array of User classes.

/**
 * @var User[]
 */
var $users = array();

You also can see the type of the array in a list of class members when you do completion of $this->...

Something like this?

$(menu).css("top", targetE1.y + "px"); 
$(menu).css("left", targetE1.x - widthOfMenu + "px");

"A destructor wouldn't even help you here. It's the event listeners themselves that still reference your object, so it would not be able to get garbage-collected before they are unregistered."

Not so. The purpose of a destructor is to allow the item that registered the listeners to unregister them. Once an object has no other references to it, it will be garbage collected.

For instance, in AngularJS, when a controller is destroyed, it can listen for a destroy event and respond to it. This isn't the same as having a destructor automatically called, but it's close, and gives us the opportunity to remove listeners that were set when the controller was initialized.

// Set event listeners, hanging onto the returned listener removal functions
function initialize() {
    $scope.listenerCleanup = [];
    $scope.listenerCleanup.push( $scope.$on( EVENTS.DESTROY, instance.onDestroy) );
    $scope.listenerCleanup.push( $scope.$on( AUTH_SERVICE_RESPONSES.CREATE_USER.SUCCESS, instance.onCreateUserResponse ) );
    $scope.listenerCleanup.push( $scope.$on( AUTH_SERVICE_RESPONSES.CREATE_USER.FAILURE, instance.onCreateUserResponse ) );
}

// Remove event listeners when the controller is destroyed
function onDestroy(){
    $scope.listenerCleanup.forEach( remove => remove() );
}

So if you're using Vscode and Mingw then you should first make sure that the bin folder of the mingw is included in the environment path and it is preferred to change the mingw32-make.exe to make to ease the task and then create a makefile and include this code in it .

all:
    gcc -o filename filename.c
    ./filename

Then save the makefile and open Vscode Code terminal and write make. Then makefile will get executed.

The simplest way I've made is :

1. Make repository on github with your dataset
2. Clone Your repository with ! git clone --recursive [GITHUB LINK REPO]
3. Find where is your data ( !ls command )
4. Open file with pandas as You do it in normal jupyter notebook.

If you're using glibc, you can set the MALLOC_CHECK_ environment variable to 2, this will cause glibc to use an error tolerant version of malloc, which will cause your program to abort at the point where the double free is done.

You can set this from gdb by using the set environment MALLOC_CHECK_ 2 command before running your program; the program should abort, with the free() call visible in the backtrace.

see the man page for malloc() for more information

You can also..do in this way,

List<List<Object>> Parent=new  List<List<Object>>();

List<Object> Child=new List<Object>();
child.Add(2349);
child.Add("Daft Punk");
child.Add("Human");
.
.
Parent.Add(child);

if you need another item(child), create a new instance of child,

Child=new List<Object>();
child.Add(2323);
child.Add("asds");
child.Add("jshds");
.
.
Parent.Add(child);

Call visudo and add this:

user1 ALL=(user2) NOPASSWD: /home/user2/bin/test.sh

The command paths must be absolute! Then call sudo -u user2 /home/user2/bin/test.sh from a user1 shell. Done.

You can get this exception when the Edmx is in one project and you are using it from another.

The reason is Res://*/ is a uri which points to resources in the CURRENT assembly. If the Edm is defined in a different assembly from the code which is using it, res://*/ is not going to work because the resource cannot be found.

Instead of specifying ‘*’, you need to provide the full name of the assembly instead (including public key token). Eg:

res://YourDataAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=abcdefabcedf/YourEdmxFileName.csdl|res://...

A better way to construct connection strings is with EntityConnectionStringBuilder:

public static string GetSqlCeConnectionString(string fileName)
{
    var csBuilder = new EntityConnectionStringBuilder();

    csBuilder.Provider = "System.Data.SqlServerCe.3.5";
    csBuilder.ProviderConnectionString = string.Format("Data Source={0};", fileName);

    csBuilder.Metadata = string.Format("res://{0}/YourEdmxFileName.csdl|res://{0}/YourEdmxFileName.ssdl|res://{0}/YourEdmxFileName.msl", 
        typeof(YourObjectContextType).Assembly.FullName);

    return csBuilder.ToString();
}

public static string GetSqlConnectionString(string serverName, string databaseName)
{
    SqlConnectionStringBuilder providerCs = new SqlConnectionStringBuilder();

    providerCs.DataSource = serverName;
    providerCs.InitialCatalog = databaseName;
    providerCs.IntegratedSecurity = true;

    var csBuilder = new EntityConnectionStringBuilder();

    csBuilder.Provider = "System.Data.SqlClient";
    csBuilder.ProviderConnectionString = providerCs.ToString();

    csBuilder.Metadata = string.Format("res://{0}/YourEdmxFileName.csdl|res://{0}/YourEdmxFileName.ssdl|res://{0}/YourEdmxFileName.msl",
        typeof(YourObjectContextType).Assembly.FullName);

    return csBuilder.ToString();
}

If you still encounter the exception, open the assembly in reflector and check the filenames for your .csdl, .ssdl and .msl files. When the resources have different names to the ones specified in the metadata value, it’s not going to work.

You can install multiple Java runtimes under Windows (including Windows 7) as long as each is in their own directory.

For example, if you are running Win 7 64-bit, or Win Server 2008 R2, you may install 32-bit JRE in "C:\Program Files (x86)\Java\jre6" and 64-bit JRE in "C:\Program Files\Java\jre6", and perhaps IBM Java 6 in "C:\Program Files (x86)\IBM\Java60\jre".

The Java Control Panel app theoretically has the ability to manage multiple runtimes: Java tab >> View... button

There are tabs for User and System settings. You can add additional runtimes with Add or Find, but once you have finished adding runtimes and hit OK, you have to hit Apply in the main Java tab frame, which is not as obvious as it could be - otherwise your changes will be lost.

If you have multiple versions installed, only the main version will auto-update. I have not found a solution to this apart from the weak workaround of manually updating whenever I see an auto-update, so I'd love to know if anyone has a fix for that.

Most Java IDEs allow you to select any Java runtime on your machine to build against, but if not using an IDE, you can easily manage this using environment variables in a cmd window. Your PATH and the JAVA_HOME variable determine which runtime is used by tools run from the shell. Set the JAVA_HOME to the jre directory you want and put the bin directory into your path (and remove references to other runtimes) - with IBM you may need to add multiple bin directories. This is pretty much all the set up that the default system Java does. You can also set CLASSPATH, ANT_HOME, MAVEN_HOME, etc. to unique values to match your runtime.

I used the solution below to export all datagrid values to a text file, rather than using the column names you can use the column index instead.

foreach (DataGridViewRow row in xxxCsvDG.Rows)
{
    File.AppendAllText(csvLocation, row.Cells[0].Value + "," + row.Cells[1].Value + "," + row.Cells[2].Value + "," + row.Cells[3].Value + Environment.NewLine);
}

Vue2: if you only want to detect change on input blur (e.g. after press enter or click somewhere else) do (more info here)

<input @change="foo" v-model... >

If you wanna detect single character changes (during user typing) use

<input @keydown="foo" v-model... >

You can also use @keyup and @input events. If you wanna to pass additional parameters use in template e.g. @keyDown="foo($event, param1, param2)". Comparision below (editable version here)

Starting with Sql Server 2012: string concatenation function CONCAT converts to string implicitly. Therefore, another option is

SELECT Id AS 'PatientId',
       CONCAT(ParentId,'') AS 'ParentId'
FROM Patients

CONCAT converts null values to empty strings.

Some will consider this hacky, because it merely exploits a side effect of a function while the function itself isn't required for the task in hand.

If you would like to show it in a new window, you could use Tkinter + PIL library, like so:

import tkinter as tk
from PIL import ImageTk, Image

def show_imge(path):
    image_window = tk.Tk()
    img = ImageTk.PhotoImage(Image.open(path))
    panel = tk.Label(image_window, image=img)
    panel.pack(side="bottom", fill="both", expand="yes")
    image_window.mainloop()

This is a modified example that can be found all over the web.

In VueJS you can loop through an array like this : const array1 = ['a', 'b', 'c'];

Array.from(array1).forEach(element => 
 console.log(element)
      );

in my case I want to loop through files and add their types to another array:

 Array.from(files).forEach((file) => {
       if(this.mediaTypes.image.includes(file.type)) {
            this.media.images.push(file)
             console.log(this.media.images)
       }
   }

While it might not be the best approach the closest equivalent I can think of that works is this with the support/compatibility library

getActivity().getSupportFragmentManager().beginTransaction().remove(this).commit();

or

getActivity().getFragmentManager().beginTransaction().remove(this).commit();

otherwise.

In addition you can use the backstack and pop it. However keep in mind that the fragment might not be on the backstack (depending on the fragmenttransaction that got it there..) or it might not be the last one that got onto the stack so popping the stack could remove the wrong one...

You can try getting a list from the map object by just iterating each item in the object and store it in a different variable.

a = map(chr, [66, 53, 0, 94])
b = [item for item in a]
print(b)
>>>['B', '5', '\x00', '^']

It will be faster because it doesnt have to wait for locks

if re.search(r'pattern', string):

Simple if-test:

if re.search(r'ing\b', "seeking a great perhaps"):     # any words end with ing?
    print("yes")

Pattern check, extract a substring, case insensitive:

match_object = re.search(r'^OUGHT (.*) BE$', "ought to be", flags=re.IGNORECASE)
if match_object:
    assert "to" == match_object.group(1)     # what's between ought and be?

Notes:

• Use re.search() not re.match. Match restricts to the start of strings, a confusing convention if you ask me. If you do want a string-starting match, use caret or \A instead, re.search(r'^...', ...)

• Use raw string syntax r'pattern' for the first parameter. Otherwise you would need to double up backslashes, as in re.search('ing\\b', ...)

• In this example, \b is a special sequence meaning word-boundary in regex. Not to be confused with backspace.

• re.search() returns None if it doesn't find anything, which is always falsy.

• re.search() returns a Match object if it finds anything, which is always truthy.

• a group is what matched inside parentheses

• group numbering starts at 1

You can use curl instead.

version=1.2.3
artifact="artifact"
repoId=repositoryId
groupId=org/myorg
REPO_URL=http://localhost:8081/nexus

curl -u username:password --upload-file filename.tgz $REPO_URL/content/repositories/$repoId/$groupId/$artefact/$version/$artifact-$version.tgz

Another angle on this is returning an Exception, NOT throwing one, from the processing code.

I needed to do this with a templating framework I'm writing. If the user attempts to access a property that doesn't exist on the data, I return the error from deep within the processing function, rather than throwing it.

Then, in the calling code, I can decide whether to throw this returned error, causing the try() to catch(), or just continue:

// process the template
    try
    {
        // this function will pass back a value, or a TemplateExecption if invalid
            $result = $this->process($value);

        // if the result is an error, choose what to do with it
            if($result instanceof TemplateExecption)
            {
                if(DEBUGGING == TRUE)
                {
                    throw($result); // throw the original error
                }
                else
                {
                    $result = NULL; // ignore the error
                }
            }
    }

// catch TemplateExceptions
    catch(TemplateException $e)
    {
        // handle template exceptions
    }

// catch normal PHP Exceptions
    catch(Exception $e)
    {
        // handle normal exceptions
    }

// if we get here, $result was valid, or ignored
    return $result;

The result of this is I still get the context of the original error, even though it was thrown at the top.

Another option might be to return a custom NullObject or a UnknownProperty object and compare against that before deciding to trip the catch(), but as you can re-throw errors anyway, and if you're fully in control of the overall structure, I think this is a neat way round the issue of not being able to continue try/catches.

Whenever possible, avoid applying functions to a column in the where clause:

SELECT *
  FROM table_name
 WHERE timestamp >= UNIX_TIMESTAMP('2010-10-01 00:00:00') 
   AND timestamp <  UNIX_TIMESTAMP('2010-11-01 00:00:00');

Applying a function to the timestamp column (e.g., FROM_UNIXTIME(timestamp) = ...) makes indexing much harder.

Start with Firebug and IE Debugger.

Be careful with debuggers in JavaScript though. Every once in a while they will affect the environment just enough to cause some of the errors you are trying to debug.

Examples:

For Internet Explorer, it's generally a gradual slowdown and is some kind of memory leak type deal. After a half hour or so I need to restart. It seems to be fairly regular.

For Firebug, it's probably been more than a year so it may have been an older version. As a result, I don't remember the specifics, but basically the code was not running correctly and after trying to debug it for a while I disabled Firebug and the code worked fine.

AppSettings.Set does not persist the changes to your configuration file. It just changes it in memory. If you put a breakpoint on System.Configuration.ConfigurationManager.AppSettings.Set("lang", lang);, and add a watch for System.Configuration.ConfigurationManager.AppSettings[0] you will see it change from "English" to "Russian" when that line of code runs.

The following code (used in a console application) will persist the change.

class Program
{
    static void Main(string[] args)
    {
        UpdateSetting("lang", "Russian");
    }

    private static void UpdateSetting(string key, string value)
    {
        Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        configuration.AppSettings.Settings[key].Value = value;
        configuration.Save();

        ConfigurationManager.RefreshSection("appSettings");
    }
}

From this post: http://vbcity.com/forums/t/152772.aspx

One major point to note with the above is that if you are running this from the debugger (within Visual Studio) then the app.config file will be overwritten each time you build. The best way to test this is to build your application and then navigate to the output directory and launch your executable from there. Within the output directory you will also find a file named YourApplicationName.exe.config which is your configuration file. Open this in Notepad to see that the changes have in fact been saved.

When sending data to a web server, the data has to be a string (here). You can convert a JavaScript object into a string with JSON.stringify(). Here is a working example:

var fs = require('fs');

var originalNote = {
  title: 'Meeting',
  description: 'Meeting John Doe at 10:30 am'
};

var originalNoteString = JSON.stringify(originalNote);

fs.writeFileSync('notes.json', originalNoteString);

var noteString = fs.readFileSync('notes.json');

var note = JSON.parse(noteString);

console.log(`TITLE: ${note.title} DESCRIPTION: ${note.description}`);

Hope it could help.

I wanted a function that would join tables without requiring you to define the columns using an anonymous type selector, but had a hard time finding any. I ended up having to make my own. Hopefully this will help anyone in the future who searches for this:

private DataTable JoinDataTables(DataTable t1, DataTable t2, params Func<DataRow, DataRow, bool>[] joinOn)
{
    DataTable result = new DataTable();
    foreach (DataColumn col in t1.Columns)
    {
        if (result.Columns[col.ColumnName] == null)
            result.Columns.Add(col.ColumnName, col.DataType);
    }
    foreach (DataColumn col in t2.Columns)
    {
        if (result.Columns[col.ColumnName] == null)
            result.Columns.Add(col.ColumnName, col.DataType);
    }
    foreach (DataRow row1 in t1.Rows)
    {
        var joinRows = t2.AsEnumerable().Where(row2 =>
            {
                foreach (var parameter in joinOn)
                {
                    if (!parameter(row1, row2)) return false;
                }
                return true;
            });
        foreach (DataRow fromRow in joinRows)
        {
            DataRow insertRow = result.NewRow();
            foreach (DataColumn col1 in t1.Columns)
            {
                insertRow[col1.ColumnName] = row1[col1.ColumnName];
            }
            foreach (DataColumn col2 in t2.Columns)
            {
                insertRow[col2.ColumnName] = fromRow[col2.ColumnName];
            }
            result.Rows.Add(insertRow);
        }
    }
    return result;
}

An example of how you might use this:

var test = JoinDataTables(transactionInfo, transactionItems,
               (row1, row2) =>
               row1.Field<int>("TransactionID") == row2.Field<int>("TransactionID"));

One caveat: This is certainly not optimized, so be mindful when getting to row counts above 20k. If you know that one table will be larger than the other, try to put the smaller one first and the larger one second.

This is what worked for me: https://github.com/bumptech/glide/wiki/Custom-targets#overriding-default-behavior

import com.bumptech.glide.Glide;
import com.bumptech.glide.request.transition.Transition;
import com.bumptech.glide.request.target.BitmapImageViewTarget;

...

Glide.with(yourFragment)
  .load("yourUrl")
  .asBitmap()
  .into(new BitmapImageViewTarget(yourImageView) {
    @Override
    public void onResourceReady(Bitmap bitmap, Transition<? super Bitmap> anim) {
        super.onResourceReady(bitmap, anim);
        Palette.generateAsync(bitmap, new Palette.PaletteAsyncListener() {  
            @Override
            public void onGenerated(Palette palette) {
                // Here's your generated palette
                Palette.Swatch swatch = palette.getDarkVibrantSwatch();
                int color = palette.getDarkVibrantColor(swatch.getTitleTextColor());
            }
        });
    }
});

I know it's a very old comment, but still:

Instead of using single bracket (dfTest['A']), use double brackets (dfTest[['A']]).

i.e: min_max_scaler.fit_transform(dfTest[['A']]).

I believe this will give the desired result.

document.getElementById('Id').value='new value';

https://developer.mozilla.org/en-US/docs/Web/API/document.getElementById

for your exact sample, it should be like this.

DECLARE @m INT
SET @m = 321%11
SELECT @m

You can use max() to get the max value. The max function can also return the index of the maximum value in the vector. To get this, assign the result of the call to max to a two element vector instead of just a single variable.

e.g. z is your array,

>> [x, y] = max(z)

x =

7

y =

4

Here, 7 is the largest number at the 4th position(index).

Use ArrayList.set

list.set(2, "New");

Here is a more complete looking jquery 1.11.x $.ajax() usage:

<script type="text/javascript">
    function uploadProgressHandler(event) {
        $("#loaded_n_total").html("Uploaded " + event.loaded + " bytes of " + event.total);
        var percent = (event.loaded / event.total) * 100;
        var progress = Math.round(percent);
        $("#uploadProgressBar").html(progress + " percent na ang progress");
        $("#uploadProgressBar").css("width", progress + "%");
        $("#status").html(progress + "% uploaded... please wait");
    }

    function loadHandler(event) {
        $("#status").html(event.target.responseText);
        $("#uploadProgressBar").css("width", "0%");
    }

    function errorHandler(event) {
        $("#status").html("Upload Failed");
    }

    function abortHandler(event) {
        $("#status").html("Upload Aborted");
    }

    $("#uploadFile").click(function (event) {
        event.preventDefault();
        var file = $("#fileUpload")[0].files[0];
        var formData = new FormData();
        formData.append("file1", file);

        $.ajax({
            url: 'http://testarea.local/UploadWithProgressBar1/file_upload_parser.php',
            method: 'POST',
            type: 'POST',
            data: formData,
            contentType: false,
            processData: false,
            xhr: function () {
                var xhr = new window.XMLHttpRequest();
                xhr.upload.addEventListener("progress",
                    uploadProgressHandler,
                    false
                );
                xhr.addEventListener("load", loadHandler, false);
                xhr.addEventListener("error", errorHandler, false);
                xhr.addEventListener("abort", abortHandler, false);

                return xhr;
            }
        });
    });
</script>

If you're on OSX you can also find it your keychain. Your developer and distribution certificates have your Team ID in them.

Applications -> Utilities -> Keychain Access.

Under the 'login' Keychain, go into the 'Certificates' category.

Scroll to find your development or distribution certificate. They will read:

iPhone Distribution: Team Name (certificate id)

or

iPhone Developer: Team Name (certificate id)

Simply double-click on the item, and the

"Organizational Unit"

is the "Team ID"

Note that this is the only way to find your

"Personal team" ID

You can not find the "Personal team" ID on the Apple web interface.

For example, if you are automating a build from say Unity, during development you'll want it to appear in Xcode as your "Personal team" - this is the only way to get that value.

Since I just learned about this cool thing(indexing into lists from within a format string) I'm adding to this old question.

s = '{x[0]} BLAH {x[1]} FOO {x[2]} BAR'
x = ['1', '2', '3']
print (s.format (x=x))

Output:

1 BLAH 2 FOO 3 BAR

However, I still haven't figured out how to do slicing(inside of the format string '"{x[2:4]}".format...,) and would love to figure it out if anyone has an idea, however I suspect that you simply cannot do that.

Benjamin Peterson is correct about the use of inspect.isclass() for this job. But note that you can test if a Class object is a specific Class, and therefore implicitly a Class, using the built-in function issubclass. Depending on your use-case this can be more pythonic.

from typing import Type, Any
def isclass(cl: Type[Any]):
    try:
        return issubclass(cl, cl)
    except TypeError:
        return False

Can then be used like this:

>>> class X():
...     pass
... 
>>> isclass(X)
True
>>> isclass(X())
False

Ctrl + H is the best way! Remember to copy the string before you start searching!

I just figured out one method to avoid above errors.

Save to database

user.first_name = u'Rytis'.encode('unicode_escape')
user.last_name = u'Slatkevicius'.encode('unicode_escape')
user.save()
>>> SUCCEED

print user.last_name
>>> Slatkevi\u010dius
print user.last_name.decode('unicode_escape')
>>> Slatkevicius

Is this the only method to save strings like that into a MySQL table and decode it before rendering to templates for display?

How to use a clock and do assertions

This example shows how to generate a clock, and give inputs and assert outputs for every cycle. A simple counter is tested here.

The key idea is that the process blocks run in parallel, so the clock is generated in parallel with the inputs and assertions.

library ieee;
use ieee.std_logic_1164.all;

entity counter_tb is
end counter_tb;

architecture behav of counter_tb is
    constant width : natural := 2;
    constant clk_period : time := 1 ns;

    signal clk : std_logic := '0';
    signal data : std_logic_vector(width-1 downto 0);
    signal count : std_logic_vector(width-1 downto 0);

    type io_t is record
        load : std_logic;
        data : std_logic_vector(width-1 downto 0);
        count : std_logic_vector(width-1 downto 0);
    end record;
    type ios_t is array (natural range <>) of io_t;
    constant ios : ios_t := (
        ('1', "00", "00"),
        ('0', "UU", "01"),
        ('0', "UU", "10"),
        ('0', "UU", "11"),

        ('1', "10", "10"),
        ('0', "UU", "11"),
        ('0', "UU", "00"),
        ('0', "UU", "01")
    );
begin
    counter_0: entity work.counter port map (clk, load, data, count);

    process
    begin
        for i in ios'range loop
            load <= ios(i).load;
            data <= ios(i).data;
            wait until falling_edge(clk);
            assert count = ios(i).count;
        end loop;
        wait;
    end process;

    process
    begin
        for i in 1 to 2 * ios'length loop
            wait for clk_period / 2;
            clk <= not clk;
        end loop;
        wait;
    end process;
end behav;

The counter would look like this:

library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all; -- unsigned

entity counter is
    generic (
        width : in natural := 2
    );
    port (
        clk, load : in std_logic;
        data : in std_logic_vector(width-1 downto 0);
        count : out std_logic_vector(width-1 downto 0)
    );
end entity counter;

architecture rtl of counter is
    signal cnt : unsigned(width-1 downto 0);
begin
    process(clk) is
    begin
        if rising_edge(clk) then
            if load = '1' then
                cnt <= unsigned(data);
            else
                cnt <= cnt + 1;
            end if;
        end if;
    end process;
    count <= std_logic_vector(cnt);
end architecture rtl;

For substring(startIndex, endIndex), startIndex is inclusive and endIndex are exclusive. The startIndex and endIndex are very confusing. I would understand substring(startIndex, length) to remember that.

TouchableOpacity receives activeOpacity. You can do something like this

<TouchableOpacity activeOpacity={enabled ? 0.5 : 1}>
</TouchableOpacity>

So if it's enabled, it will look normal, otherwise, it will look just like touchablewithoutfeedback.

On Windows, if you installed it as a service, go to Services (Start ? Run: services.msc), find Jenkins, right click ? Restart.

If it does not help (UI is not responding) open the Windows Task Manager ? Processes, kill the java.exe process, and restart the service once again.

Here in this case, we are having 3 parameter's in the Method namely ModelandView.
According to this question, the first parameter is easily understood. It represents the View which will be displayed to the client.
The other two parameters are just like The Pointer and The Holder
Hence you can sum it up like this

ModelAndView(View, Pointer, Holder);

The Pointer just points the information in the The Holder

When the Controller binds the View with this information, then in the said process, you can use The Pointer in the JSP page to access the information stored in The Holder to display that respected information to the client.
Here is the visual depiction of the respected process.

return new ModelAndView("welcomePage", "WelcomeMessage", message);

This is the solution for people that do care about accessibility.

Please, don't use outline:none; for disabling the focus outline. You are killing accessibility of the web if you do this. There is a accessible way of doing this.

Check out this article that I've written to explain how to remove the border in an accessible way.

The idea in short is to only show the outline border when we detect a keyboard user. Once a user starts using his mouse we disable the outline. As a result you get the best of the two.

This looks like a pretty clean solution: UIDevice BIdentifier

Another mock serious answer for a silly question:

The real answer is, use an appropriate data structure. Human genealogy cannot fully be expressed using a pure tree with no cycles. You should use some sort of graph. Also, talk to an anthropologist before going any further with this, because there are plenty of other places similar errors could be made trying to model genealogy, even in the most simple case of "Western patriarchal monogamous marriage."

Even if we want to ignore locally taboo relationships as discussed here, there are plenty of perfectly legal and completely unexpected ways to introduce cycles into a family tree.

For example: http://en.wikipedia.org/wiki/Cousin_marriage

Basically, cousin marriage is not only common and expected, it is the reason humans have gone from thousands of small family groups to a worldwide population of 6 billion. It can't work any other way.

There really are very few universals when it comes to genealogy, family and lineage. Almost any strict assumption about norms suggesting who an aunt can be, or who can marry who, or how children are legitimized for the purpose of inheritance, can be upset by some exception somewhere in the world or history.

Really stupid question: Are you sure the string is being truncated, and not just broken at the linebreak you specify (and possibly not showing in your interface)? Ie, do you expect the field to show as

This will be inserted \n This will not be

or

This will be inserted

This will not be

Also, what interface are you using? Is it possible that something along the way is eating your backslashes?

int position = 0;
listview.setItemChecked(position, true);
View wantedView = adapter.getView(position, null, listview);

Safer C code (unless you have other methods of handling /0):

return (_divisor > 0) ? ((_dividend + (_divisor - 1)) / _divisor) : _dividend;

This doesn't handle the problems that occur from having an incorrect return value as a result of your invalid input data, of course.

It looks like the Django REST framework uses the HTTP accept header in a Request in order to automatically determine which renderer to use:

http://www.django-rest-framework.org/api-guide/renderers/

Using the HTTP accept header may provide an alternative source for your "if something".

Here is the code with tests cases ;) :

@Test
public void testNullStringShouldReturnStringWithSpaces() throws Exception {
    String fixedString = writeAtFixedLength(null, 5);
    assertEquals(fixedString, "     ");
}

@Test
public void testEmptyStringReturnStringWithSpaces() throws Exception {
    String fixedString = writeAtFixedLength("", 5);
    assertEquals(fixedString, "     ");
}

@Test
public void testShortString_ReturnSameStringPlusSpaces() throws Exception {
    String fixedString = writeAtFixedLength("aa", 5);
    assertEquals(fixedString, "aa   ");
}

@Test
public void testLongStringShouldBeCut() throws Exception {
    String fixedString = writeAtFixedLength("aaaaaaaaaa", 5);
    assertEquals(fixedString, "aaaaa");
}


private String writeAtFixedLength(String pString, int lenght) {
    if (pString != null && !pString.isEmpty()){
        return getStringAtFixedLength(pString, lenght);
    }else{
        return completeWithWhiteSpaces("", lenght);
    }
}

private String getStringAtFixedLength(String pString, int lenght) {
    if(lenght < pString.length()){
        return pString.substring(0, lenght);
    }else{
        return completeWithWhiteSpaces(pString, lenght - pString.length());
    }
}

private String completeWithWhiteSpaces(String pString, int lenght) {
    for (int i=0; i<lenght; i++)
        pString += " ";
    return pString;
}

I like TDD ;)

it works correctly for me:

git branch | xargs git branch -d

git branch | xargs git branch -D

delete all local branches

It looks like you may be confused as to when commands are run. In your example, you are calling the get method before the GUI has a chance to be displayed on the screen (which happens after you call mainloop.

Try adding a button that calls the get method. This is much easier if you write your application as a class. For example:

import tkinter as tk

class SampleApp(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.entry = tk.Entry(self)
        self.button = tk.Button(self, text="Get", command=self.on_button)
        self.button.pack()
        self.entry.pack()

    def on_button(self):
        print(self.entry.get())

app = SampleApp()
app.mainloop()

Run the program, type into the entry widget, then click on the button.

I've been using something like this for a while to kill my sessions on a shared server. The first line of the 'where' can be removed to kill all non 'sys' sessions:

BEGIN
  FOR c IN (
      SELECT s.sid, s.serial#
      FROM v$session s
      WHERE (s.Osuser = 'MyUser' or s.MACHINE = 'MyNtDomain\MyMachineName')
      AND s.USERNAME <> 'SYS'
      AND s.STATUS <> 'KILLED'
  )
  LOOP
      EXECUTE IMMEDIATE 'alter system kill session ''' || c.sid || ',' || c.serial# || '''';
  END LOOP;
END;

2019 Update

This updates the answers with the latest Fetch API and doesn't need jQuery.

Disclaimer: doesn't work on IE, Opera Mini and older browsers. See caniuse.

Basic Fetch

It could be as simple as:

  fetch(`https://example.com/upload.php`, {method:"POST", body:blobData})
                .then(response => console.log(response.text()))

Fetch with Error Handling

After adding error handling, it could look like:

fetch(`https://example.com/upload.php`, {method:"POST", body:blobData})
            .then(response => {
                if (response.ok) return response;
                else throw Error(`Server returned ${response.status}: ${response.statusText}`)
            })
            .then(response => console.log(response.text()))
            .catch(err => {
                alert(err);
            });

PHP Code

This is the server-side code in upload.php.

<?php    
    // gets entire POST body
    $data = file_get_contents('php://input');
    // write the data out to the file
    $fp = fopen("path/to/file", "wb");

    fwrite($fp, $data);
    fclose($fp);
?>

This is valid YAML:

jobs:
 - name: A
   schedule: "0 0/5 * 1/1 * ? *"
   type: mongodb.cluster
   config:
     host: mongodb://localhost:27017/admin?replicaSet=rs
     minSecondaries: 2
     minOplogHours: 100
     maxSecondaryDelay: 120
 - name: B
   schedule: "0 0/5 * 1/1 * ? *"
   type: mongodb.cluster
   config:
     host: mongodb://localhost:27017/admin?replicaSet=rs
     minSecondaries: 2
     minOplogHours: 100
     maxSecondaryDelay: 120

Note, that every '-' starts new element in the sequence. Also, indentation of keys in the map should be exactly same.

You can use:

 echo '<?php if(function_exists("my_func")) echo "function exists"; ' | php

The short tag "< ?=" can be helpful too:

 echo '<?= function_exists("foo") ? "yes" : "no";' | php
 echo '<?= 8+7+9 ;' | php

The closing tag "?>" is optional, but don't forget the final ";"!

Tagging on to mecca831's answer:

ssh -v -i generated-key.pem [email protected]

[[email protected] ~]$ sudo passwd ec2-user newpassword newpassword

[[email protected] ~]$ sudo vi /etc/ssh/sshd_config Modify the file as follows:

    # To disable tunneled clear text passwords, change to no here!
    PasswordAuthentication yes
    #PermitEmptyPasswords no
    # EC2 uses keys for remote access
    #PasswordAuthentication no

Save

[[email protected] ~]$ sudo service sshd stop [[email protected] ~]$ sudo service sshd start

you should be able to exit and ssh in as follows:

ssh [email protected]

and be prompted for password no longer needing the key.

String jsonInput = "{ \"hi\": \"Assume this is the JSON\"} ";
com.fasterxml.jackson.databind.ObjectMapper mapper =
    new com.fasterxml.jackson.databind.ObjectMapper();
MyClass myObject = objectMapper.readValue(jsonInput, MyClass.class);

If your JSON input in has more properties than your POJO has and you just want to ignore the extras in Jackson 2.4, you can configure your ObjectMapper as follows. This syntax is different from older Jackson versions. (If you use the wrong syntax, it will silently do nothing.)

mapper.disable(com.fasterxml.jackson.databind.DeserializationFeature.FAIL_ON_UNK??NOWN_PROPERTIES);

First of all make sure you java is working or not run this command in cmd

 C:\>java -version

if it's working it will show this output:-

C:\>java -version
java version "1.8.0_74"
Java(TM) SE Runtime Environment (build 1.8.0_74-b02)
Java HotSpot(TM) Client VM (build 25.74-b02, mixed mode)

step 1. First set your java_home[C:\Program Files\Java\jdk1.8.0_74] path in user variable.

step 2. Then set MAVEN_HOME[C:\Program Files\maven\apache-maven-3.3.9] path in system variable and make sure your maven folder should be present in C folder only.

step 3. Then set M2 path in system variable and give maven bin location there i.e.[C:\Program Files\maven\apache-maven-3.3.9\bin].

Step 4. Then set new system variable i.e. variable name = MAVEN_OPTS in and variable value =-Xms256m -Xmx512m

Step 5. Then edit path/system path variable be care full don't remove anything from there simply add java_home path i.e=;C:\Program Files\Java\jdk1.8.0_74 and M2 variable=;%M2% in the end.

Step 6. To make sure maven is now working or not run this command in cmd

> C:\>mvn --version

if it's working it will show this result :-

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-

Referring to the answers above, I am only adding this to help clarify things. It is possible to use HttpClient from .Net 4.0, and you have to install the package from here

However, the text is very confusion and contradicts itself.

This package is not supported in Visual Studio 2010, and is only required for projects targeting .NET Framework 4.5, Windows 8, or Windows Phone 8.1 when consuming a library that uses this package.

But underneath it states that these are the supported platforms.

Supported Platforms:

• .NET Framework 4

• Windows 8

• Windows Phone 8.1

• Windows Phone Silverlight 7.5

• Silverlight 4

• Portable Class Libraries

Ignore what it ways about targeting .Net 4.5. This is wrong. The package is all about using HttpClient in .Net 4.0. However, you may need to use VS2012 or higher. Not sure if it works in VS2010, but that may be worth testing.

In my case i was missing trailing / in path.

find /var/opt/gitlab/backups/ -name *.tar

$query_string = "";

if ($_POST) {
    $kv = array();
    foreach ($_POST as $key => $value) {
        $kv[] = stripslashes($key) . "=" . stripslashes($value);
    }
    $query_string = join("&", $kv);
}

if (!function_exists('curl_init')){
    die('Sorry cURL is not installed!');
}

$url = 'https://www.abcd.com/servlet/';

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($kv));
curl_setopt($ch, CURLOPT_POSTFIELDS, $query_string);

curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);

$result = curl_exec($ch);

curl_close($ch);

Three working examples

I had a similar situation, but I used .find() after struggling with .closest() for a long time with many variations.

The Example Code

// Allows contain functions to work, ignores case sensitivity

jQuery.expr[':'].contains = function(obj, index, meta, stack) {
    result = false;
    theList = meta[3].split("','");
    var contents = (obj.textContent || obj.innerText || jQuery(obj).text() || '')
    for (x=0; x<theList.length; x++) {
        if (contents.toLowerCase().indexOf(theList[x].toLowerCase()) >= 0) {
            return true;
        }
    }
    return false;
};

$(document).ready(function() {
    var refreshId = setInterval( function() {
        $("#out:contains('foo', 'test456')").find(".inner").css('width', '50px', 'important');
    }, 1000); // Rescans every 1000 ms
});

Alternative

$('.inner').each(function () {
    this.style.setProperty('height', '50px', 'important');
});

$('#out').find('.inner').css({ 'height': '50px'});

Working: http://jsfiddle.net/fx4mbp6c/

You say

The string is exactly what was written to the file (with the addition of a "\0" at the end, but I don't think that even does anything).

In fact, it does do something (it causes your code to throw a FormatException:"Invalid character in a Base-64 string") because the Convert.FromBase64String does not consider "\0" to be a valid Base64 character.

  byte[] data1 = Convert.FromBase64String("AAAA\0"); // Throws exception
  byte[] data2 = Convert.FromBase64String("AAAA");   // Works

Solution: Get rid of the zero termination. (Maybe call .Trim("\0"))

Notes:

The MSDN docs for Convert.FromBase64String say it will throw a FormatException when

The length of s, ignoring white space characters, is not zero or a multiple of 4.

-or-

The format of s is invalid. s contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters.

and that

The base 64 digits in ascending order from zero are the uppercase characters 'A' to 'Z', lowercase characters 'a' to 'z', numerals '0' to '9', and the symbols '+' and '/'.

Arrays in JavaScript don't use strings as keys. You will probably find that the value is there, but the key is an integer.

If you make Dict into an object, this will work:

var dict = {};
var addPair = function (myKey, myValue) {
    dict[myKey] = myValue;
};
var giveValue = function (myKey) {
    return dict[myKey];
};

The myKey variable is already a string, so you don't need more quotes.

The function could be called as if it was in the same JS File as long as the file containing the definition of the function has been loaded before the first use of the function.

I.e.

File1.js

function alertNumber(number) {
    alert(number);
}

File2.js

function alertOne() {
     alertNumber("one");
}

HTML

<head>
....
    <script src="File1.js" type="text/javascript"></script> 
    <script src="File2.js" type="text/javascript"></script> 
....
</head>
<body>
....
    <script type="text/javascript">
       alertOne();
    </script>
....
</body>

The other way won't work. As correctly pointed out by Stuart Wakefield. The other way will also work.

HTML

<head>
....
    <script src="File2.js" type="text/javascript"></script> 
    <script src="File1.js" type="text/javascript"></script> 
....
</head>
<body>
....
    <script type="text/javascript">
       alertOne();
    </script>
....
</body>

What will not work would be:

HTML

<head>
....
    <script src="File2.js" type="text/javascript"></script> 
    <script type="text/javascript">
       alertOne();
    </script>
    <script src="File1.js" type="text/javascript"></script> 
....
</head>
<body>
....
</body>

Although alertOne is defined when calling it, internally it uses a function that is still not defined (alertNumber).

Was just facing the same problem, java 8 on ubuntu

then came across https://stackoverflow.com/a/53016532/1676516

It seems a recent bug in the surefire plugin version 2.22.1 with java 8 https://issues.apache.org/jira/browse/SUREFIRE-1588

followed the suggested workaround through local mvn settings ~/.m2/settings.xml

Following are steps to kill server process:

1. lsof -i tcp:3000

2. kill -9 1234

where 1234 is the PID of process: localhost:3000 display in step 1.

OR

Remove file(server.pid) under Rails.root/tmp/pids/ and restart server.

OR

open app in another port by using command:

rails s -p 3001

This was an enormously helpful link to find:

http://php.net/manual/en/migration56.openssl.php

An official document describing the changes made to open ssl in PHP 5.6 From here I learned of one more parameter I should have set to false: "verify_peer_name"=>false

Note: This has very significant security implications. Disabling verification potentially permits a MITM attacker to use an invalid certificate to eavesdrop on the requests. While it may be useful to do this in local development, other approaches should be used in production.

So my working code looks like this:

<?php
$arrContextOptions=array(
    "ssl"=>array(
        "verify_peer"=>false,
        "verify_peer_name"=>false,
    ),
);  

$response = file_get_contents("https://maps.co.weber.ut.us/arcgis/rest/services/SDE_composite_locator/GeocodeServer/findAddressCandidates?Street=&SingleLine=3042+N+1050+W&outFields=*&outSR=102100&searchExtent=&f=json", false, stream_context_create($arrContextOptions));

echo $response; ?>

The only good solution to this problem can be found in the gulp documentation:

var gulp = require('gulp');

// takes in a callback so the engine knows when it'll be done
gulp.task('one', function(cb) {
  // do stuff -- async or otherwise
  cb(err); // if err is not null and not undefined, the orchestration will stop, and 'two' will not run
});

// identifies a dependent task must be complete before this one begins
gulp.task('two', ['one'], function() {
  // task 'one' is done now
});

gulp.task('default', ['one', 'two']);
// alternatively: gulp.task('default', ['two']);

What about this?

  }

  @Override
  public String toString() {
    return printTree(0);
  }

  private static final int indent = 2;

  private String printTree(int increment) {
    String s = "";
    String inc = "";
    for (int i = 0; i < increment; ++i) {
      inc = inc + " ";
    }
    s = inc + head;
    for (Tree<T> child : leafs) {
      s += "\n" + child.printTree(increment + indent);
    }
    return s;
  }
}

As already mentioned, usually the comparison is done through subtraction.
For example, X86 Assembly/Control Flow.

At the hardware level there are special digital circuits for doing the calculations, like adders.

If you know the ID's rather than the strings, use this approach:

where mylookuptablecolumn IN (myarrayorcommadelimitedarray)

Just make sure that myarrayorcommadelimitedarray is not put in string quotes.

works if you want A OR B, but not AND.

Hopefully this helps someone out there.

For platform I was specifying "Any CPU", changed it to "AnyCPU" and that fixed the problem.

msbuild C:\Users\Project\Project.publishproj /p:Platform="AnyCPU"  /p:DeployOnBuild=true /p:PublishProfile=local /p:Configuration=Debug

If you look at your .csproj file you'll see the correct platform name to use.

Open the Access Database, you will see Table, Query, Report, Module & Macro.
This contains the macros which can be used to invoke common MS-Access actions in a sequence.

how about simply:

VERY EASY:

just use this to replace all white spaces with -:

For question #1, let's break it into two parts. First, increment any document that has "items.item_name" equal to "my_item_two". For this you'll have to use the positional "$" operator. Something like:

 db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } , 
                {$inc : {"items.$.price" : 1} } , 
                false , 
                true);

Note that this will only increment the first matched subdocument in any array (so if you have another document in the array with "item_name" equal to "my_item_two", it won't get incremented). But this might be what you want.

The second part is trickier. We can push a new item to an array without a "my_item_two" as follows:

 db.bar.update( {user_id : 123456, "items.item_name" : {$ne : "my_item_two" }} , 
                {$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
                false , 
                true);

For your question #2, the answer is easier. To increment the total and the price of item_three in any document that contains "my_item_three," you can use the $inc operator on multiple fields at the same time. Something like:

db.bar.update( {"items.item_name" : {$ne : "my_item_three" }} ,
               {$inc : {total : 1 , "items.$.price" : 1}} ,
               false ,
               true);

vector<char> vec;
//fill the vector;
std::string s(vec.begin(), vec.end());

The book is a bit dated with respect to subclass-superclass calling. It's also a little dated with respect to subclassing built-in classes.

It looks like this nowadays:

class FileInfo(dict):
    """store file metadata"""
    def __init__(self, filename=None):
        super(FileInfo, self).__init__()
        self["name"] = filename

Note the following:

1. We can directly subclass built-in classes, like dict, list, tuple, etc.

2. The super function handles tracking down this class's superclasses and calling functions in them appropriately.

Here is the Jquery browser detect plugin to identify browser/os detection.

You can use this for styling purpose after including the plugin.

$("html").addClass($.os.name);
$("body").addClass($.browser.className);
$("body").addClass($.browser.name);

If you are using java Transport client 1.check 9300 is access able /open. 2.check the node and cluster name ,this should be the correct,you can check the node and cluster name by type ip:port in your browser. 3.Check the versions of your jar and Es installed version.

For many years I have always used this format:

<?php
    $data = "Hello";

    function sayHello(){
        echo $GLOBALS["data"];
    }

    sayHello();
?>

I find it straightforward and easy to follow. The $GLOBALS is how PHP lets you reference a global variable. If you have used things like $_SERVER, $_POST, etc. then you have reference a global variable without knowing it.

I was using nodemailer npm module. The below code solved the issue

     tls: {
     // do not fail on invalid certs
     rejectUnauthorized: false
     }

Without explicitly defining the height I determined I need to apply the flex value to the parent and grandparent div elements...

<div style="display: flex;">
<div style="display: flex;">
 <img alt="No, he'll be an engineer." src="theknack.png" style="margin: auto;" />
</div>
</div>

If you're using a single element (e.g. dead-centered text in a single flex element) use the following:

align-items: center;
display: flex;
justify-content: center;

Solved, at least at the point of the question.

I searched in the web before asking, an there were no conclusive solution, the reason why this error is: lib1.so and lib2.so are not OK, very probably where not compiled for a 64 PC, but for a 32 bits machine otherwise lib3.so is a 64 bits lib. At least that is my hipothesis.

VERY unfortunately ldconfig doesn't give a clean error message informing that it could not load the library, it only pumps:

ldconfig: /folder_where_the_wicked_lib_is/ is not a symbolic link

I solved this when I removed the libs not found by ldd over the binary. Now it's easier that I know where lies the problem.

My ld version: GNU ld version 2.20.51, and I don't know if a most recent version has a better message for its users.

Thanks.

In XML 1.0, the XML Declaration is optional. See section 2.8 of the XML 1.0 Recommendation, where it says it "should" be used -- which means it is recommended, but not mandatory. In XML 1.1, however, the declaration is mandatory. See section 2.8 of the XML 1.1 Recommendation, where it says "MUST" be used. It even goes on to state that if the declaration is absent, that automatically implies the document is an XML 1.0 document.

Note that in an XML Declaration the encoding and standalone are both optional. Only the version is mandatory. Also, these are not attributes, so if they are present they must be in that order: version, followed by any encoding, followed by any standalone.

<?xml version="1.0"?>
<?xml version="1.0" encoding="UTF-8"?>
<?xml version="1.0" standalone="yes"?>
<?xml version="1.0" encoding="UTF-16" standalone="yes"?>

If you don't specify the encoding in this way, XML parsers try to guess what encoding is being used. The XML 1.0 Recommendation describes one possible way character encoding can be autodetected. In practice, this is not much of a problem if the input is encoded as UTF-8, UTF-16 or US-ASCII. Autodetection doesn't work when it encounters 8-bit encodings that use characters outside the US-ASCII range (e.g. ISO 8859-1) -- avoid creating these if you can.

The standalone indicates whether the XML document can be correctly processed without the DTD or not. People rarely use it. These days, it is a bad to design an XML format that is missing information without its DTD.

Update:

A "prolog error/invalid utf-8 encoding" error indicates that the actual data the parser found inside the file did not match the encoding that the XML declaration says it is. Or in some cases the data inside the file did not match the autodetected encoding.

Since your file contains a byte-order-mark (BOM) it should be in UTF-16 encoding. I suspect that your declaration says <?xml version="1.0" encoding="UTF-8"?> which is obviously incorrect when the file has been changed into UTF-16 by NotePad. The simple solution is to remove the encoding and simply say <?xml version="1.0"?>. You could also edit it to say encoding="UTF-16" but that would be wrong for the original file (which wasn't in UTF-16) or if the file somehow gets changed back to UTF-8 or some other encoding.

Don't bother trying to remove the BOM -- that's not the cause of the problem. Using NotePad or WordPad to edit XML is the real problem!

Pandas timestamp differences returns a datetime.timedelta object. This can easily be converted into hours by using the *as_type* method, like so

import pandas
df = pandas.DataFrame(columns=['to','fr','ans'])
df.to = [pandas.Timestamp('2014-01-24 13:03:12.050000'), pandas.Timestamp('2014-01-27 11:57:18.240000'), pandas.Timestamp('2014-01-23 10:07:47.660000')]
df.fr = [pandas.Timestamp('2014-01-26 23:41:21.870000'), pandas.Timestamp('2014-01-27 15:38:22.540000'), pandas.Timestamp('2014-01-23 18:50:41.420000')]
(df.fr-df.to).astype('timedelta64[h]')

to yield,

0    58
1     3
2     8
dtype: float64

git branch --set-upstream master origin/master

This will add the following info to your config file:

[branch "master"]
    remote = origin
    merge = refs/heads/master

If you have branch.autosetuprebase = always then it will also add:

    rebase = true

Solution for those working with Huawei phones - You will get this error when ADB interface is not installed. Check if you have installed Huawei HiSuite. USB driver gets installed when you install HiSuite (I suppose this is true for most of the new phones that come with a Sync Software). If the ADB interface is installed on your computer you should see 'Android Composite ADB Interface' under Android Phone in your Device Manager as shown in this picture.

scp -r C:/site user@server_ip:path

path is the place, where site will be copied into the remote server

EDIT: As I said in my comment, try pscp, as you want to use scp using PuTTY.

The other option is WinSCP

If you are trying to "Submit and Reset" the the "form" with one Button click, Try this!

Here I have used jQuery function, it can be done by simple JavaScript also...

        <form id="form_data">
           <input type="anything"  name="anything" />
           <input type="anything"  name="anything" />

             <!-- Save and Reset button -->
           <button type="button" id="btn_submit">Save</button>
           <button type="reset" id="btn_reset" style="display: none;"></button>
        </form>

<script type="text/javascript">
$(function(){
    $('#btn_submit').click(function(){
        // Do what ever you want
       $('#btn_reset').click();  // Clicking reset button
    });
});
</script>

Move is doing the same = copy and delete old one.

File.Move(@"C:\ScanPDF\Test.pdf", @"C:\BackupPDF\" + string.Format("backup-{0:yyyy-MM-dd_HH:mm:ss}.pdf", DateTime.Now));

I wasn't satisfied with what was offered, so here's my proposal, using jQuery :

            <div id="playlist">
                <audio id="player" controls preload="metadata" volume="1">
                  <source src="" type="audio/mpeg">
                  Sorry, this browser doesn't support HTML 5.0
                </audio>
                <ul></ul>
            </div>

            <script>
                var folder = "audio";
                var playlist = [
                    "example1.mp3",
                    "example2.mp3"
                ];
                for (var i in playlist) {
                    jQuery('#playlist ul').append('<li>'+playlist[i]+'</li>');
                }

                var player = document.getElementById('player');
                var playing = playlist[0];
                player.src = folder + '/' + playing;

                function display(id) {
                    var list = jQuery('#playlist ul').children();
                    list.removeClass('playing');
                    jQuery(list[id]).addClass('playing');
                }

                display(0);

                player.onended = function(){
                    var ind_next = playlist.indexOf(playing) + 1;

                    if (ind_next !== 0) {
                        player.src = folder + '/' + playlist[ind_next];
                        playing = player.src;
                        display(ind_next)
                        player.play();
                    }
                }
            </script>

You only have to edit the playlist array, and you're done

• A unit test tests an independent unit of behavior. What is a unit of behavior? It's the smallest piece of the system that can be independently unit tested. (This definition is actually circular, IOW it's really not a definition at all, but it seems to work quite well in practice, because you can sort-of understand it intuitively.)

• A functional test tests an independent piece of functionality.

• A unit of behavior is very small: while I absolutely dislike this stupid "one unit test per method" mantra, from a size perspective it is about right. A unit of behavior is something between a part of a method and maybe a couple of methods. At most an object, but not more than one.

• A piece of functionality usually comprises many methods and cuts across several objects and often through multiple architectural layers.

• A unit test would be something like: when I call the validate_country_code() function and pass it the country code 'ZZ' it should return false.

• A functional test would be: when I fill out the shipping form with a country code of ZZ, I should be redirected to a help page which allows me to pick my country code out of a menu.

• Unit tests are written by developers, for developers, from the developer's perspective.

• Functional tests may be user facing, in which case they are written by developers together with users (or maybe with the right tools and right users even by the users themselves), for users, from the user's perspective. Or they may be developer facing (e.g. when they describe some internal piece of functionality that the user doesn't care about), in which case they are written by developers, for developers, but still from the user's perspective.

• In the former case, the functional tests may also serve as acceptance tests and as an executable encoding of functional requirements or a functional specification, in the latter case, they may also serve as integration tests.

• Unit tests change frequently, functional tests should never change within a major release.

I have the same problem with a element in a webform. So what I did to fix it was validate. if(Object === 'null') do something

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

    final TextView mTvTitle = (TextView)findViewById(R.id.tvTitle1);

    mTvTitle.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;
            final int DRAWABLE_TOP = 1;
            final int DRAWABLE_RIGHT = 2;
            final int DRAWABLE_BOTTOM = 3;

            if(event.getAction() == MotionEvent.ACTION_UP) {
                if(event.getRawX() <= (mTvTitle.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width()))  {
                    // your action here
                    Intent intent = new Intent(DeAddExpences.this,DeHomeActivity.class);
                    startActivity(intent);
                    return true;
                }
            }
            return true;
        }
    });

From my experiences the first few frames that are captured when using:

frame = cvQueryFrame( capture );

Tend to be blank. You may want to wait a short while(about 3 seconds) and then try to capture the image.

A slightly faster approach than looping on xrange(N) is:

import itertools

for _ in itertools.repeat(None, N):
    do_something()

True jQuery way if you want to change directly the DOM without messing with inner HTML:

$('#text').find('br').prepend(document.createTextNode('\n')).remove();

Prepend inserts inside the element, before() is the method we need here:

$('#text').find('br').before(document.createTextNode('\n')).remove();

Code will find any <br> elements, insert raw text with new line character and then remove the <br> elements.

This should be faster if you work with long texts since there are no string operations here.

To display the new lines:

$('#text').css('white-space', 'pre-line');

I found the syslog module to make it quite easy to get the basic logging behavior you describe:

import syslog
syslog.syslog("This is a test message")
syslog.syslog(syslog.LOG_INFO, "Test message at INFO priority")

There are other things you could do, too, but even just the first two lines of that will get you what you've asked for as I understand it.

This is a mix of the two previous answers:

  PreparedStatement ps = c.prepareStatement("INSERT INTO employees VALUES (?, ?)");

  ps.setString(1, "John");
  ps.setString(2,"Doe");
  ps.addBatch();

  ps.clearParameters();
  ps.setString(1, "Dave");
  ps.setString(2,"Smith");
  ps.addBatch();

  ps.clearParameters();
  int[] results = ps.executeBatch();

Make sure that st_new.sh does something at the end what you can recognize (like touch /tmp/st_new.tmp when you remove the file first and always start one instance of st_new.sh).
Then make a polling loop. First sleep the normal time you think you should wait, and wait short time in every loop. This will result in something like

max_retry=20
retry=0
sleep 10 # Minimum time for st_new.sh to finish
while [ ${retry} -lt ${max_retry} ]; do
   if [ -f /tmp/st_new.tmp ]; then
      break # call results.sh outside loop
   else
      (( retry = retry + 1 ))
      sleep 1
   fi
done
if [ -f /tmp/st_new.tmp ]; then
   source ../../results.sh 
   rm -f /tmp/st_new.tmp
else
   echo Something wrong with st_new.sh
fi

use,

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); //before     
dialog.setContentView(R.layout.logindialog);

print myRDD.take(n)

Where n is the number of lines and myRDD is wc in your case.

Note if you have so many tabs open that Google Chrome is only showing the favicons then Google Chrome won't show the favicon for the selected tab, so if you keep reloading the tab with your page loaded in order to see your new favicon you will only see the text of your page's title.

You will need to reload your page, and then select a different tab in order to see your favicon.

drop table test

create table test(
    CollectionDate date NULL,
    CollectionTime  [time](0) NULL,
    CollectionDateTime as (isnull(convert(datetime,CollectionDate)+convert(datetime,CollectionTime),CollectionDate))
-- if CollectionDate is datetime no need to convert it above
)

insert test (CollectionDate, CollectionTime)
values ('2013-12-10', '22:51:19.227'),
       ('2013-12-10', null),
       (null, '22:51:19.227')

select * from test

CollectionDate  CollectionTime  CollectionDateTime
2013-12-10      22:51:19        2013-12-10 22:51:19.000
2013-12-10      NULL            2013-12-10 00:00:00.000
NULL            22:51:19        NULL

To literally fix your example you would use this:

Sub Normalize()


    Dim Ticker As Range
    Sheets("Sheet1").Activate
    Set Ticker = Range(Cells(2, 1), Cells(65, 1))
    Ticker.Copy

    Sheets("Sheet2").Select
    Cells(1, 1).PasteSpecial xlPasteAll



End Sub

To Make slight improvments on it would be to get rid of the Select and Activates:

Sub Normalize()
    With Sheets("Sheet1")
        .Range(.Cells(2, 1), .Cells(65, 1)).Copy Sheets("Sheet2").Cells(1, 1)
    End With
End Sub

but using the clipboard takes time and resources so the best way would be to avoid a copy and paste and just set the values equal to what you want.

Sub Normalize()
Dim CopyFrom As Range

Set CopyFrom = Sheets("Sheet1").Range("A2", [A65])
Sheets("Sheet2").Range("A1").Resize(CopyFrom.Rows.Count).Value = CopyFrom.Value

End Sub

To define the CopyFrom you can use anything you want to define the range, You could use Range("A2:A65"), Range("A2",[A65]), Range("A2", "A65") all would be valid entries. also if the A2:A65 Will never change the code could be further simplified to:

Sub Normalize()

Sheets("Sheet2").Range("A1:A65").Value = Sheets("Sheet1").Range("A2:A66").Value

End Sub

I added the Copy from range, and the Resize property to make it slightly more dynamic in case you had other ranges you wanted to use in the future.
