I asked this a while back. The answer is basically that it doesn't work. :(

Have a look at Cassini. This is basically what Visual Studio uses for its built-in debug web server. I've used it with Umbraco and it seems quite good.

Swift 4.0 code (Here we go again)

The called action should marked like this because that is the syntax for swift function for exporting functions into objective c language.

@objc func deleteAction(sender: UIButton) {
}

create some working button:

let deleteButton = UIButton(type: .roundedRect)
deleteButton.setTitle("Delete", for: [])
deleteButton.addTarget(self, action: #selector( 
MyController.deleteAction(sender:)), for: .touchUpInside)

Here is my working solution with search and clear icon for Angularjs\Bootstrap with CSS.

    <div class="form-group has-feedback has-clear">
                    <input type="search" class="form-control removeXicon" ng-model="filter" style="max-width:100%" placeholder="Search..." />
                    <div ng-switch on="!!filter">
                        <div ng-switch-when="false">
                            <span class="glyphicon glyphicon-search form-control-feedback"></span>
                        </div>
                        <div ng-switch-when="true">
                            <span class="glyphicon glyphicon-remove-sign form-control-feedback" ng-click="$parent.filter = ''" style="pointer-events: auto; text-decoration: none;cursor: pointer;"></span>
                        </div>
                    </div>

i found textView.setTypeface(Typeface.DEFAULT_BOLD); to be the simplest method.

tk.mainloop() blocks. It means that execution of your Python commands halts there. You can see that by writing:

while 1:
    ball.draw()
    tk.mainloop()
    print("hello")   #NEW CODE
    time.sleep(0.01)

You will never see the output from the print statement. Because there is no loop, the ball doesn't move.

On the other hand, the methods update_idletasks() and update() here:

while True:
    ball.draw()
    tk.update_idletasks()
    tk.update()

...do not block; after those methods finish, execution will continue, so the while loop will execute over and over, which makes the ball move.

An infinite loop containing the method calls update_idletasks() and update() can act as a substitute for calling tk.mainloop(). Note that the whole while loop can be said to block just like tk.mainloop() because nothing after the while loop will execute.

However, tk.mainloop() is not a substitute for just the lines:

tk.update_idletasks()
tk.update()

Rather, tk.mainloop() is a substitute for the whole while loop:

while True:
    tk.update_idletasks()
    tk.update()

Response to comment:

Here is what the tcl docs say:

Update idletasks

This subcommand of update flushes all currently-scheduled idle events from Tcl's event queue. Idle events are used to postpone processing until “there is nothing else to do”, with the typical use case for them being Tk's redrawing and geometry recalculations. By postponing these until Tk is idle, expensive redraw operations are not done until everything from a cluster of events (e.g., button release, change of current window, etc.) are processed at the script level. This makes Tk seem much faster, but if you're in the middle of doing some long running processing, it can also mean that no idle events are processed for a long time. By calling update idletasks, redraws due to internal changes of state are processed immediately. (Redraws due to system events, e.g., being deiconified by the user, need a full update to be processed.)

APN As described in Update considered harmful, use of update to handle redraws not handled by update idletasks has many issues. Joe English in a comp.lang.tcl posting describes an alternative:

So update_idletasks() causes some subset of events to be processed that update() causes to be processed.

From the update docs:

update ?idletasks?

The update command is used to bring the application “up to date” by entering the Tcl event loop repeatedly until all pending events (including idle callbacks) have been processed.

If the idletasks keyword is specified as an argument to the command, then no new events or errors are processed; only idle callbacks are invoked. This causes operations that are normally deferred, such as display updates and window layout calculations, to be performed immediately.

KBK (12 February 2000) -- My personal opinion is that the [update] command is not one of the best practices, and a programmer is well advised to avoid it. I have seldom if ever seen a use of [update] that could not be more effectively programmed by another means, generally appropriate use of event callbacks. By the way, this caution applies to all the Tcl commands (vwait and tkwait are the other common culprits) that enter the event loop recursively, with the exception of using a single [vwait] at global level to launch the event loop inside a shell that doesn't launch it automatically.

The commonest purposes for which I've seen [update] recommended are:

1. Keeping the GUI alive while some long-running calculation is executing. See Countdown program for an alternative. 2) Waiting for a window to be configured before doing things like geometry management on it. The alternative is to bind on events such as that notify the process of a window's geometry. See Centering a window for an alternative.

What's wrong with update? There are several answers. First, it tends to complicate the code of the surrounding GUI. If you work the exercises in the Countdown program, you'll get a feel for how much easier it can be when each event is processed on its own callback. Second, it's a source of insidious bugs. The general problem is that executing [update] has nearly unconstrained side effects; on return from [update], a script can easily discover that the rug has been pulled out from under it. There's further discussion of this phenomenon over at Update considered harmful.

.....

Is there any chance I can make my program work without the while loop?

Yes, but things get a little tricky. You might think something like the following would work:

class Ball:
    def __init__(self, canvas, color):
        self.canvas = canvas
        self.id = canvas.create_oval(10, 10, 25, 25, fill=color)
        self.canvas.move(self.id, 245, 100)

    def draw(self):
        while True:
           self.canvas.move(self.id, 0, -1)

ball = Ball(canvas, "red")
ball.draw()
tk.mainloop()

The problem is that ball.draw() will cause execution to enter an infinite loop in the draw() method, so tk.mainloop() will never execute, and your widgets will never display. In gui programming, infinite loops have to be avoided at all costs in order to keep the widgets responsive to user input, e.g. mouse clicks.

So, the question is: how do you execute something over and over again without actually creating an infinite loop? Tkinter has an answer for that problem: a widget's after() method:

from Tkinter import *
import random
import time

tk = Tk()
tk.title = "Game"
tk.resizable(0,0)
tk.wm_attributes("-topmost", 1)

canvas = Canvas(tk, width=500, height=400, bd=0, highlightthickness=0)
canvas.pack()

class Ball:
    def __init__(self, canvas, color):
        self.canvas = canvas
        self.id = canvas.create_oval(10, 10, 25, 25, fill=color)
        self.canvas.move(self.id, 245, 100)

    def draw(self):
        self.canvas.move(self.id, 0, -1)
        self.canvas.after(1, self.draw)  #(time_delay, method_to_execute)


       

ball = Ball(canvas, "red")
ball.draw()  #Changed per Bryan Oakley's comment
tk.mainloop()

The after() method doesn't block (it actually creates another thread of execution), so execution continues on in your python program after after() is called, which means tk.mainloop() executes next, so your widgets get configured and displayed. The after() method also allows your widgets to remain responsive to other user input. Try running the following program, and then click your mouse on different spots on the canvas:

from Tkinter import *
import random
import time

root = Tk()
root.title = "Game"
root.resizable(0,0)
root.wm_attributes("-topmost", 1)

canvas = Canvas(root, width=500, height=400, bd=0, highlightthickness=0)
canvas.pack()

class Ball:
    def __init__(self, canvas, color):
        self.canvas = canvas
        self.id = canvas.create_oval(10, 10, 25, 25, fill=color)
        self.canvas.move(self.id, 245, 100)

        self.canvas.bind("<Button-1>", self.canvas_onclick)
        self.text_id = self.canvas.create_text(300, 200, anchor='se')
        self.canvas.itemconfig(self.text_id, text='hello')

    def canvas_onclick(self, event):
        self.canvas.itemconfig(
            self.text_id, 
            text="You clicked at ({}, {})".format(event.x, event.y)
        )

    def draw(self):
        self.canvas.move(self.id, 0, -1)
        self.canvas.after(50, self.draw)


       

ball = Ball(canvas, "red")
ball.draw()  #Changed per Bryan Oakley's comment.
root.mainloop()

git revert doesn't take a filename parameter. Do you want git checkout?

Personally I would use d3-dsv library to do this. Why to reinvent the wheel?

import { csvFormat } from 'd3-dsv';
/**
 * Based on input data convert it to csv formatted string
 * @param (Array) columnsToBeIncluded array of column names (strings)
 *                which needs to be included in the formated csv
 * @param {Array} input array of object which need to be transformed to string
 */
export function convertDataToCSVFormatString(input, columnsToBeIncluded = []) {
  if (columnsToBeIncluded.length === 0) {
    return csvFormat(input);
  }
  return csvFormat(input, columnsToBeIncluded);
}

With tree-shaking you can just import that particular function from d3-dsv library

When you read in git tag man page:

One important aspect of git is it is distributed, and being distributed largely means there is no inherent "upstream" or "downstream" in the system.

, that simply means there is no absolute upstream repo or downstream repo.
Those notions are always relative between two repos and depends on the way data flows:

If "yourRepo" has declared "otherRepo" as a remote one, then:

• you are pulling from upstream "otherRepo" ("otherRepo" is "upstream from you", and you are "downstream for otherRepo").
• you are pushing to upstream ("otherRepo" is still "upstream", where the information now goes back to).

Note the "from" and "for": you are not just "downstream", you are "downstream from/for", hence the relative aspect.

The DVCS (Distributed Version Control System) twist is: you have no idea what downstream actually is, beside your own repo relative to the remote repos you have declared.

• you know what upstream is (the repos you are pulling from or pushing to)
• you don't know what downstream is made of (the other repos pulling from or pushing to your repo).

Basically:

In term of "flow of data", your repo is at the bottom ("downstream") of a flow coming from upstream repos ("pull from") and going back to (the same or other) upstream repos ("push to").

You can see an illustration in the git-rebase man page with the paragraph "RECOVERING FROM UPSTREAM REBASE":

It means you are pulling from an "upstream" repo where a rebase took place, and you (the "downstream" repo) is stuck with the consequence (lots of duplicate commits, because the branch rebased upstream recreated the commits of the same branch you have locally).

That is bad because for one "upstream" repo, there can be many downstream repos (i.e. repos pulling from the upstream one, with the rebased branch), all of them having potentially to deal with the duplicate commits.

Again, with the "flow of data" analogy, in a DVCS, one bad command "upstream" can have a "ripple effect" downstream.

Note: this is not limited to data.
It also applies to parameters, as git commands (like the "porcelain" ones) often call internally other git commands (the "plumbing" ones). See rev-parse man page:

Many git porcelainish commands take mixture of flags (i.e. parameters that begin with a dash '-') and parameters meant for the underlying git rev-list command they use internally and flags and parameters for the other commands they use downstream of git rev-list. This command is used to distinguish between them.

I was also getting the error:

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

... with a Xamarin Forms Android-targeting application attempting to request resources from an API provider that required TLS 1.3.

The solution was to update the project configuration to swap out the Xamarin "managed" (.NET) http client (that doesn't support TLS 1.3 as of Xamarin Forms v2.5), and instead use the android native client.

It's a simple project toggle in visual studio. See screenshot below.

• Project Properties
• Android Options
• Advanced
• List item
• Change "HttpClient implementation" to "Android"
• Change SSL/TLS implementation to "Native TLS 1.2+"

For me it is works as it is. Where exactly is problem?

public static T FindThing<T>(this IList collection, int id) where T : IThing, new()
{
    foreach (T thing in collection)
    {
        if (thing.Id == id)
            return thing;
        }
    }

    return null; //work
    return (T)null; //work
    return null as T; //work
    return default(T); //work


}

use further as

rs.getString(1);
rs.getInt(2);

1, 2 is the column number of table and set int or string as per data-type of coloumn

function escapeHTML(string)
    { 
        var pre = document.createElement('pre');
        var text = document.createTextNode(string);
        pre.appendChild(text);
        return pre.innerHTML;
}//end escapeHTML

it will return the escaped Html

I use https://github.com/yabawock/bootstrap-sass-rails

Which is pretty much straight forward install, fast gem updates and followups and quick fixes in case is needed.

    <script type="text/javascript">
        $(window).on('load',function(){
            setTimeout(function(){ alert(" //show popup"); }, 5000); 
        });
    </script>

The best way to do it would be to submit the contents of the div to the server and open a new window where the server could put those contents into the new window.

If that's not an option you can try to use a client-side language like javascript to hide everything on the page except that div and then print the page...

This works for me

webView.setOnTouchListener(new View.OnTouchListener() {
                            @Override
                            public boolean onTouch(View v, MotionEvent event) {
                                // Do what you want
                                return false;
                            }
                        });

dochoffiday's answer is a great starting point, but for me it did not cut it (the CSS part needed a buff) so I made a modified version with several improvements.

See it in action, then come back for the description.

JavaScript

(function ($) {
    $.fn.styleTable = function (options) {
        var defaults = {
            css: 'ui-styled-table'
        };
        options = $.extend(defaults, options);

        return this.each(function () {
            $this = $(this);
            $this.addClass(options.css);

            $this.on('mouseover mouseout', 'tbody tr', function (event) {
                $(this).children().toggleClass("ui-state-hover",
                                               event.type == 'mouseover');
            });

            $this.find("th").addClass("ui-state-default");
            $this.find("td").addClass("ui-widget-content");
            $this.find("tr:last-child").addClass("last-child");
        });
    };
})(jQuery);

Differences with the original version:

• the default CSS class has been changed to ui-styled-table (it sounds more consistent)
• the .live call was replaced with the recommended .on for jQuery 1.7 upwards
• the explicit conditional has been replaced by .toggleClass (a terser equivalent)
• code that sets the misleadingly-named CSS class first on table cells has been removed
• the code that dynamically adds .last-child to the last table row is necessary to fix a visual glitch on Internet Explorer 7 and Internet Explorer 8; for browsers that support :last-child it is not necessary

CSS

/* Internet Explorer 7: setting "separate" results in bad visuals; all other browsers work fine with either value. */
/* If set to "separate", then this rule is also needed to prevent double vertical borders on hover:
table.ui-styled-table tr * + th, table.ui-styled-table tr * + td  { border-left-width: 0px !important; } */
table.ui-styled-table { border-collapse: collapse; }

/* Undo the "bolding" that jQuery UI theme may cause on hovered elements
/* Internet Explorer 7: does not support "inherit", so use a MS proprietary expression along with an Internet Explorer <= 7 targeting hack
        to make the visuals consistent across all supported browsers */
table.ui-styled-table td.ui-state-hover {
    font-weight: inherit;
    *font-weight: expression(this.parentNode.currentStyle['fontWeight']);
}

/* Initally remove bottom border for all cells. */
table.ui-styled-table th, table.ui-styled-table td { border-bottom-width: 0px !important; }

/* Hovered-row cells should show bottom border (will be highlighted) */
table.ui-styled-table tbody tr:hover th,
table.ui-styled-table tbody tr:hover td
{ border-bottom-width: 1px !important; }

/* Remove top border if the above row is being hovered to prevent double horizontal borders. */
table.ui-styled-table tbody tr:hover + tr th,
table.ui-styled-table tbody tr:hover + tr td
{ border-top-width: 0px !important; }

/* Last-row cells should always show bottom border (not necessarily highlighted if not hovered). */
/* Internet Explorer 7, Internet Explorer 8: selector dependent on CSS classes because of no support for :last-child */
table.ui-styled-table tbody tr.last-child th,
table.ui-styled-table tbody tr.last-child td
{ border-bottom-width: 1px !important; }

/* Last-row cells should always show bottom border (not necessarily highlighted if not hovered). */
/* Internet Explorer 8 BUG: if these (unsupported) selectors are added to a rule, other selectors for that rule will stop working as well! */
/* Internet Explorer 9 and later, Firefox, Chrome: make sure the visuals are working even without the CSS classes crutch. */
table.ui-styled-table tbody tr:last-child th,
table.ui-styled-table tbody tr:last-child td
{ border-bottom-width: 1px !important; }

Notes

I have tested this on Internet Explorer 7 and upwards, Firefox 11 and Google Chrome 18 and confirmed that it works perfectly. I have not tested reasonably earlier versions of Firefox and Chrome or any version of Opera; however, those browsers are well-known for good CSS support and since we are not using any bleeding-edge functionality here I assume it will work just fine there as well.

If you are not interested in Internet Explorer 7 support there is one CSS attribute (introduced with the star hack) that can go.

If you are not interested in Internet Explorer 8 support either, the CSS and JavaScript related to adding and targeting the last-child CSS class can go as well.

Building upon the fiddle from @tim, this version tightens the scope and formatting, and converts bind() -> on(). It's designed to bind on a dedicated td as the handle instead of the entire row. In my use case, I have input fields so the "drag anywhere on the row" approach felt confusing.

Tested working on desktop. Only partial success with mobile touch. Can't get it to run correctly on SO's runnable snippet for some reason...

let ns = {
  drag: (e) => {
    let el = $(e.target),
      d = $('body'),
      tr = el.closest('tr'),
      sy = e.pageY,
      drag = false,
      index = tr.index();

    tr.addClass('grabbed');

    function move(e) {
      if (!drag && Math.abs(e.pageY - sy) < 10)
        return;
      drag = true;
      tr.siblings().each(function() {
        let s = $(this),
          i = s.index(),
          y = s.offset().top;
        if (e.pageY >= y && e.pageY < y + s.outerHeight()) {
          i < tr.index() ? s.insertAfter(tr) : s.insertBefore(tr);
          return false;
        }
      });
    }

    function up(e) {
      if (drag && index !== tr.index())
        drag = false;

      d.off('mousemove', move).off('mouseup', up);
      //d.off('touchmove', move).off('touchend', up); //failed attempt at touch compatibility
      tr.removeClass('grabbed');
    }
    d.on('mousemove', move).on('mouseup', up);
    //d.on('touchmove', move).on('touchend', up);
  }
};

$(document).ready(() => {
  $('body').on('mousedown touchstart', '.drag', ns.drag);
});

.grab {
  cursor: grab;
  user-select: none
}

I manage my configurations with the help of django-split-settings.

It is a drop-in replacement for the default settings. It is simple, yet configurable. And refactoring of your exisitng settings is not required.

Here's a small example (file example/settings/__init__.py):

from split_settings.tools import optional, include
import os

if os.environ['DJANGO_SETTINGS_MODULE'] == 'example.settings':
    include(
        'components/default.py',
        'components/database.py',
        # This file may be missing:
        optional('local_settings.py'),

        scope=globals()
    )

That's it.

Update

I wrote a blog post about managing django's settings with django-split-sttings. Have a look!

This happened to me before.

The reason was that I'm connecting android to a webview with a JS. And I sent a parameter without quotes.

js.sayHello(hello);

and when I changed it to

js.sayHello('hello');

it worked.

List.clear would remove the elements without reducing the capacity of the list.

groovy:000> mylist = [1,2,3,4,5,6,7,8,9,10,11,12]
===> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
groovy:000> mylist.elementData.length
===> 12
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@19d6af
groovy:000> mylist.clear()
===> null
groovy:000> mylist.elementData.length
===> 12
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@19d6af
groovy:000> mylist = new ArrayList();
===> []
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@2bfdff
groovy:000> mylist.elementData.length
===> 10

Here mylist got cleared, the references to the elements held by it got nulled out, but it keeps the same backing array. Then mylist was reinitialized and got a new backing array, the old one got GCed. So one way holds onto memory, the other one throws out its memory and gets reallocated from scratch (with the default capacity). Which is better depends on whether you want to reduce garbage-collection churn or minimize the current amount of unused memory. Whether the list sticks around long enough to be moved out of Eden might be a factor in deciding which is faster (because that might make garbage-collecting it more expensive).

I scripted this for my Dropbox file list.

for me the "workaround" solution was to remove the "_normal" from the end of the string

Check it out below:

• Low res image: https://pbs.twimg.com/profile_images/636894769742897152/frlgaWB8_normal.jpg

• Hi res image: https://pbs.twimg.com/profile_images/636894769742897152/frlgaWB8.jpg

One more possibility, if you don't want to use ArgumentCaptor (for example, because you're also using stubbing), is to use Hamcrest Matchers in combination with Mockito.

import org.mockito.Mockito
import org.hamcrest.Matchers
...

Mockito.verify(mockedObject).someMethodOnMockedObject(MockitoHamcrest.argThat(
    Matchers.<SomeObjectAsArgument>hasProperty("propertyName", desiredValue)));

use <strong> or <b> tag

also, you can try with css <span style="font-weight:bold">text</span>

Fast-forward merging makes sense for short-lived branches, but in a more complex history, non-fast-forward merging may make the history easier to understand, and make it easier to revert a group of commits.

Warning: Non-fast-forwarding has potential side effects as well. Please review https://sandofsky.com/blog/git-workflow.html, avoid the 'no-ff' with its "checkpoint commits" that break bisect or blame, and carefully consider whether it should be your default approach for master.

^{(From nvie.com, Vincent Driessen, post "A successful Git branching model")}

Incorporating a finished feature on develop

Finished features may be merged into the develop branch to add them to the upcoming release:

$ git checkout develop
Switched to branch 'develop'
$ git merge --no-ff myfeature
Updating ea1b82a..05e9557
(Summary of changes)
$ git branch -d myfeature
Deleted branch myfeature (was 05e9557).
$ git push origin develop

The --no-ff flag causes the merge to always create a new commit object, even if the merge could be performed with a fast-forward. This avoids losing information about the historical existence of a feature branch and groups together all commits that together added the feature.

Jakub Narebski also mentions the config merge.ff:

By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded.
When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line).
When set to 'only', only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line).

The fast-forward is the default because:

• short-lived branches are very easy to create and use in Git
• short-lived branches often isolate many commits that can be reorganized freely within that branch
• those commits are actually part of the main branch: once reorganized, the main branch is fast-forwarded to include them.

But if you anticipate an iterative workflow on one topic/feature branch (i.e., I merge, then I go back to this feature branch and add some more commits), then it is useful to include only the merge in the main branch, rather than all the intermediate commits of the feature branch.

In this case, you can end up setting this kind of config file:

[branch "master"]
# This is the list of cmdline options that should be added to git-merge 
# when I merge commits into the master branch.

# The option --no-commit instructs git not to commit the merge
# by default. This allows me to do some final adjustment to the commit log
# message before it gets commited. I often use this to add extra info to
# the merge message or rewrite my local branch names in the commit message
# to branch names that are more understandable to the casual reader of the git log.

# Option --no-ff instructs git to always record a merge commit, even if
# the branch being merged into can be fast-forwarded. This is often the
# case when you create a short-lived topic branch which tracks master, do
# some changes on the topic branch and then merge the changes into the
# master which remained unchanged while you were doing your work on the
# topic branch. In this case the master branch can be fast-forwarded (that
# is the tip of the master branch can be updated to point to the tip of
# the topic branch) and this is what git does by default. With --no-ff
# option set, git creates a real merge commit which records the fact that
# another branch was merged. I find this easier to understand and read in
# the log.

mergeoptions = --no-commit --no-ff

The OP adds in the comments:

I see some sense in fast-forward for [short-lived] branches, but making it the default action means that git assumes you... often have [short-lived] branches. Reasonable?

Jefromi answers:

I think the lifetime of branches varies greatly from user to user. Among experienced users, though, there's probably a tendency to have far more short-lived branches.

To me, a short-lived branch is one that I create in order to make a certain operation easier (rebasing, likely, or quick patching and testing), and then immediately delete once I'm done.
That means it likely should be absorbed into the topic branch it forked from, and the topic branch will be merged as one branch. No one needs to know what I did internally in order to create the series of commits implementing that given feature.

More generally, I add:

it really depends on your development workflow:

• if it is linear, one branch makes sense.
• If you need to isolate features and work on them for a long period of time and repeatedly merge them, several branches make sense.

See "When should you branch?"

Actually, when you consider the Mercurial branch model, it is at its core one branch per repository (even though you can create anonymous heads, bookmarks and even named branches)
See "Git and Mercurial - Compare and Contrast".

Mercurial, by default, uses anonymous lightweight codelines, which in its terminology are called "heads".
Git uses lightweight named branches, with injective mapping to map names of branches in remote repository to names of remote-tracking branches.
Git "forces" you to name branches (well, with the exception of a single unnamed branch, which is a situation called a "detached HEAD"), but I think this works better with branch-heavy workflows such as topic branch workflow, meaning multiple branches in a single repository paradigm.

{
  "number" : ["1","2","3"],
  "alphabet" : ["a", "b", "c"]
}

python <main module>.py does not work with relative import

The problem is relative import does not work when you run a __main__ module from the command line

python <main_module>.py

It is clearly stated in PEP 338.

The release of 2.5b1 showed a surprising (although obvious in retrospect) interaction between this PEP and PEP 328 - explicit relative imports don't work from a main module. This is due to the fact that relative imports rely on __name__ to determine the current module's position in the package hierarchy. In a main module, the value of __name__ is always '__main__', so explicit relative imports will always fail (as they only work for a module inside a package).

Cause

• Python Bug Tracker Issue1510172: Absolute/relative import not working?

The issue isn't actually unique to the -m switch. The problem is that relative imports are based on __name__, and in the main module, __name__ always has the value __main__. Hence, relative imports currently can't work properly from the main module of an application, because the main module doesn't know where it really fits in the Python module namespace (this is at least fixable in theory for the main modules executed through the -m switch, but directly executed files and the interactive interpreter are completely out of luck).

To understand further, see Relative imports in Python 3 for the detailed explanation and how to get it over.

I ended up creating a modified directive of the above code to accept input and change the format on the fly...

.directive('numericOnly', function($filter) {
  return {
      require: 'ngModel',
      link: function(scope, element, attrs, modelCtrl) {

           element.bind('keyup', function (inputValue, e) {
             var strinput = modelCtrl.$$rawModelValue;
             //filter user input
             var transformedInput = strinput ? strinput.replace(/[^,\d.-]/g,'') : null;
             //remove trailing 0
             if(transformedInput.charAt(0) <= '0'){
               transformedInput = null;
               modelCtrl.$setViewValue(transformedInput);
               modelCtrl.$render();
             }else{
               var decimalSplit = transformedInput.split(".")
               var intPart = decimalSplit[0];
               var decPart = decimalSplit[1];
               //remove previously formated number
               intPart = intPart.replace(/,/g, "");
               //split whole number into array of 3 digits
               if(intPart.length > 3){
                 var intDiv = Math.floor(intPart.length / 3);
                 var strfraction = [];
                 var i = intDiv,
                     j = 3;

                 while(intDiv > 0){
                   strfraction[intDiv] = intPart.slice(intPart.length-j,intPart.length - (j - 3));
                   j=j+3;
                   intDiv--;
                 }
                 var k = j-3;
                 if((intPart.length-k) > 0){
                   strfraction[0] = intPart.slice(0,intPart.length-k);
                 }
               }
               //join arrays
               if(strfraction == undefined){ return;}
                 var currencyformat = strfraction.join(',');
                 //check for leading comma
                 if(currencyformat.charAt(0)==','){
                   currencyformat = currencyformat.slice(1);
                 }

                 if(decPart ==  undefined){
                   modelCtrl.$setViewValue(currencyformat);
                   modelCtrl.$render();
                   return;
                 }else{
                   currencyformat = currencyformat + "." + decPart.slice(0,2);
                   modelCtrl.$setViewValue(currencyformat);
                   modelCtrl.$render();
                 }
             }
            });
      }
  };

})

In addition to the above responses, it should be noted that there is, at least in theory, no restriction whatsoever as to what kind of resources are involved in a transaction.

Most of the time, it is just a database, or multiple distinct databases, but it is also conceivable that a printer takes part in a transaction, and can cause that transaction to fail, say in the event of a paper jam.

Question?

Looking at the answers and the question, it seems the question has been modified significantly. So to answer the current question:

Convert LocalDateTime to LocalDateTime in UTC.

Timezone?

LocalDateTime does not store any information about the time-zone, it just basically holds the values of year, month, day, hour, minute, second, and smaller units. So an important question is: What is the timezone of the original LocalDateTime? It might as well be UTC already, therefore no conversion has to be made.

System Default Timezone

Considering that you asked the question anyway, you probably meant that the original time is in your system-default timezone and you want to convert it to UTC. Because usually a LocalDateTime object is created by using LocalDateTime.now() which returns the current time in the system-default timezone. In this case, the conversion would be the following:

LocalDateTime convertToUtc(LocalDateTime time) {
    return time.atZone(ZoneId.systemDefault()).withZoneSameInstant(ZoneOffset.UTC).toLocalDateTime();
}

An example of the conversion process:

2019-02-25 11:39 // [time] original LocalDateTime without a timezone
2019-02-25 11:39 GMT+1 // [atZone] converted to ZonedDateTime (system timezone is Madrid)
2019-02-25 10:39 GMT // [withZoneSameInstant] converted to UTC, still as ZonedDateTime
2019-02-25 10:39 // [toLocalDateTime] losing the timezone information

Explicit Timezone

In any other case, when you explicitly specify the timezone of the time to convert, the conversion would be the following:

LocalDateTime convertToUtc(LocalDateTime time, ZoneId zone) {
    return time.atZone(zone).withZoneSameInstant(ZoneOffset.UTC).toLocalDateTime();
}

An example of the conversion process:

2019-02-25 11:39 // [time] original LocalDateTime without a timezone
2019-02-25 11:39 GMT+2 // [atZone] converted to ZonedDateTime (zone is Europe/Tallinn)
2019-02-25 09:39 GMT // [withZoneSameInstant] converted to UTC, still as ZonedDateTime
2019-02-25 09:39 // [toLocalDateTime] losing the timezone information

The atZone() Method

The result of the atZone() method depends on the time passed as its argument, because it considers all the rules of the timezone, including Daylight Saving Time (DST). In the examples, the time was 25th February, in Europe this means winter time (no DST).

If we were to use a different date, let's say 25th August from last year, the result would be different, considering DST:

2018-08-25 11:39 // [time] original LocalDateTime without a timezone
2018-08-25 11:39 GMT+3 // [atZone] converted to ZonedDateTime (zone is Europe/Tallinn)
2018-08-25 08:39 GMT // [withZoneSameInstant] converted to UTC, still as ZonedDateTime
2018-08-25 08:39 // [toLocalDateTime] losing the timezone information

The GMT time does not change. Therefore the offsets in the other timezones are adjusted. In this example, the summer time of Estonia is GMT+3, and winter time GMT+2.

Also, if you specify a time within the transition of changing clocks back one hour. E.g. October 28th, 2018 03:30 for Estonia, this can mean two different times:

2018-10-28 03:30 GMT+3 // summer time [UTC 2018-10-28 00:30]
2018-10-28 04:00 GMT+3 // clocks are turned back 1 hour [UTC 2018-10-28 01:00]
2018-10-28 03:00 GMT+2 // same as above [UTC 2018-10-28 01:00]
2018-10-28 03:30 GMT+2 // winter time [UTC 2018-10-28 01:30]

Without specifying the offset manually (GMT+2 or GMT+3), the time 03:30 for the timezone Europe/Tallinn can mean two different UTC times, and two different offsets.

Summary

As you can see, the end result depends on the timezone of the time passed as an argument. Because the timezone cannot be extracted from the LocalDateTime object, you have to know yourself which timezone it is coming from in order to convert it to UTC.

If you are on Azure you need you can now, you need to have Manag. Studio 2014 and update hotfix: http://blogs.msdn.com/b/sqlreleaseservices/archive/2014/12/18/sql-server-2014-management-studio-updated-support-for-the-latest-azure-sql-database-update-v12-preview.aspx

Combining works if the intended result of combination is that any of them matching results in the whole regexp matching.

Putting this http://www.mredkj.com/javascript/numberFormat.html and $('.number').formatNumber(); concept together, you may use the following line of code;

e.g. <td class="number">1172907.50</td> will be formatted like <td class="number">1,172,907.50</td>

$('.number').text(function () { 
    var str = $(this).html() + ''; 
    x = str.split('.'); 
    x1 = x[0]; x2 = x.length > 1 ? '.' + x[1] : ''; 
    var rgx = /(\d+)(\d{3})/; 
    while (rgx.test(x1)) { 
        x1 = x1.replace(rgx, '$1' + ',' + '$2'); 
    } 
    $(this).html(x1 + x2); 
});

The Android support library can be imported within gradle in the dependencies :

    compile 'com.android.support:design:22.2.0'

It should be included within GradlePlease! And as an example to use it:

 <android.support.design.widget.TextInputLayout
    android:id="@+id/to_text_input_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <AutoCompleteTextView
        android:id="@+id/autoCompleteTextViewTo"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:hint="To"
        android:layout_marginTop="45dp"
        />
</android.support.design.widget.TextInputLayout>

Btw, the editor may not understand that AutoCompleteTextView is allowed within TextInputLayout.

According to the documentation, it's

CREATE TABLE something (
  column1, 
  column2, 
  column3, 
  PRIMARY KEY (column1, column2)
);

If you have d1 and d2 as your dates, the best solution is probably the following:

int days1 = d1.getTime()/(60*60*24*1000);//find the number of days since the epoch.
int days2 = d2.getTime()/(60*60*24*1000);

then just say

days2-days1

or whatever

The Java XML parser that spring uses will read the schemaLocation values and try to load them from the internet, in order to validate the XML file. Spring, in turn, intercepts those load requests and serves up versions from inside its own JAR files.

If you omit the schemaLocation, then the XML parser won't know where to get the schema in order to validate the config.

Wrap it with new Date():

{ "dt" : { "$lt" : new Date("2012-01-01T15:00:00.000Z") } }

For converting date to string check this thread

Convert java.util.Date to String

And for converting string to date try this,

import java.text.ParseException;
import java.text.SimpleDateFormat;

public class StringToDate
{
    public static void main(String[] args) throws ParseException
    {
        SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");
        String strDate = "14/03/2003 08:05:10";     
        System.out.println("Date - " + sdf.parse(strDate));
    }
}

font-size:35px;

So like this:

<html>
  <tr>
  <td style="padding-left:5px;padding-bottom:3px;"> 
    <strong style="font-size:35px;">Datum:</strong>
    <br/>
    November 2010 
  </td>
  </tr>
</html>

Although inline styles are a bad practice and you should class things. Also you should use a <strong></strong> tag instead of <b></b>

You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.

Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).

EDIT:

Here is some code:

For the UDF:

    Public Function UDF_Date(ByVal data) As Date

        UDF_Date = Now()

    End Function

As Formula in D2:

=UDF_Date(C2)

You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.

And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.

Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.

Addendum:

Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:

• The usage of the UDF is the same as described above.

• The UDF works only for single cell input ranges.

• The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.

• If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.

• The code might brake for cell-values for which conversion to string is non-deterministic.

• The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.

Make the insertion of the date conditional upon the range.

This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

Adapted from this tip and @Paul S answer

Private Sub Worksheet_Change(ByVal Target As Range)
 Dim R1 As Range
 Dim R2 As Range
 Dim InRange As Boolean
    Set R1 = Range(Target.Address)
    Set R2 = Range("C2:C20")
    Set InterSectRange = Application.Intersect(R1, R2)

  InRange = Not InterSectRange Is Nothing
     Set InterSectRange = Nothing
   If InRange = True Then
     R1.Offset(0, 1).Value = Now()
   End If
     Set R1 = Nothing
     Set R2 = Nothing
 End Sub

By using the Nuget Package Manager UI as mentioned above it helps to uninstall the nuget package first. I always have problems when going back on a nuget package version if I don't uninstall first. Some references are not cleaned properly. So I suggest the following workflow when installing an old nuget package through the Nuget Package Manager:

1. Selected your nuget server / source
2. Find and select the nuget package your want to install an older version
3. Uninstall current version
4. Click on the install drop-down > Select older version > Click Install

Good Luck :)

When you run selenium WebDriver, the WebDriver opens a remote server in your computer's local host. Now, this server, called the Selenium Server, is used to interpret your code into actions to run or "drive" the instance of a real browser known as either chromebrowser, ie broser, ff browser, etc.

So, the Selenium Server can interact with different browser properties and hence it has many "capabilities".

Now what capabilities do you desire? Consider a scenario where you are validating if files have been downloaded properly in your app but, however, you do not have a desktop automation tool. In the case where you click the download link and a desktop pop up shows up to ask where to save and/or if you want to download. Your next route to bypass that would be to suppress that pop up. How? Desired Capabilities.

There are other such examples. In summary, Selenium Server can do a lot, use Desired Capabilities to tailor it to your need.

I got an exception when using rs.last()

if(rs.last()){
    rowCount = rs.getRow(); 
    rs.beforeFirst();
}

:

java.sql.SQLException: Invalid operation for forward only resultset

it's due to by default it is ResultSet.TYPE_FORWARD_ONLY, which means you can only use rs.next()

the solution is:

stmt=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
    ResultSet.CONCUR_READ_ONLY); 

When you modifiy it a little, it works regardless which dateFormat you have set.

$("#datepicker").datepicker({
                        dateFormat: "@", // Unix timestamp
                        onSelect: function(dateText, inst){
                            addOrRemoveDate(dateText);
                        },
                        beforeShowDay: function(date){
                            var gotDate = $.inArray($.datepicker.formatDate($(this).datepicker('option', 'dateFormat'), date), dates);
                            if (gotDate >= 0) {
                                return [false,"ui-state-highlight", "Event Name"];
                            }
                            return [true, ""];
                        }
                    });     

I'm doing it like this:

1. Models are ViewScoped

2. converter:

   @Named
   @ViewScoped
   public class ViewScopedFacesConverter implements Converter, Serializable
   {
           private static final long serialVersionUID = 1L;
           private Map<String, Object> converterMap;
   
           @PostConstruct
           void postConstruct(){
               converterMap = new HashMap<>();
           }
   
           @Override
           public String getAsString(FacesContext context, UIComponent component, Object object) {
               String selectItemValue = String.valueOf( object.hashCode() ); 
               converterMap.put( selectItemValue, object );
               return selectItemValue;
           }
   
           @Override
           public Object getAsObject(FacesContext context, UIComponent component, String selectItemValue){
               return converterMap.get(selectItemValue);
           }
   }
   

and bind to component with:

 <f:converter binding="#{viewScopedFacesConverter}" />

If you will use entity id rather than hashCode you can hit a collision- if you have few lists on one page for different entities (classes) with the same id

sudo chown -R $(whoami):admin /usr/local

That will give permissions back (Homebrew installs ruby there)

MAMP takes only two highest versions of the PHP in the following folder /Application/MAMP/bin/php

As you can see here highest versions are 7.0.10 and 5.6.25

Now 7.0.10 version is removed and as you can see highest two versions are 5.6.25 and 5.5.38 as shown in preferences

Solution with backward compatibility:

SEL requestSelector = NSSelectorFromString(@"requestWhenInUseAuthorization");
if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined &&
    [self.locationManager respondsToSelector:requestSelector]) {
    [self.locationManager performSelector:requestSelector withObject:NULL];
} else {
    [self.locationManager startUpdatingLocation];
}

Setup NSLocationWhenInUseUsageDescription key in your Info.plist

If you are sending this through your own mail server you might need to add a "Sender" header which will contain an email address of from your own domain. Gmail will probably be spamming the email because the FROM address is a gmail address but has not been sent from their own server.

Trust all SSL certificates:- You can bypass SSL if you want to test on the testing server. But do not use this code for production.

This can be used for Volley in Android.

function setSelectedIndex(s, v) {
    for ( var i = 0; i < s.options.length; i++ ) {
        if ( s.options[i].value == v ) {
            s.options[i].selected = true;
            return;
        }
    }
}

Where s is the dropdown and v is the value

Android Studio -> Device File Explorer (right bottom corner) -> data -> data -> {package.id} -> shared-prefs

Note: You need to connect mobile device to android studio and selected application should be in debug mode

This is a question of style (or preference) since the interpreter does not care. Personally I would try not to make the final statement of a function which returns a value at an indent level other than the function base. The else in example 1 obscures, if only slightly, where the end of the function is.

By preference I use:

return A+1 if (A > B) else A-1

As it obeys both the good convention of having a single return statement as the last statement in the function (as already mentioned) and the good functional programming paradigm of avoiding imperative style intermediate results.

For more complex functions I prefer to break the function into multiple sub-functions to avoid premature returns if possible. Otherwise I revert to using an imperative style variable called rval. I try not to use multiple return statements unless the function is trivial or the return statement before the end is as a result of an error. Returning prematurely highlights the fact that you cannot go on. For complex functions that are designed to branch off into multiple subfunctions I try to code them as case statements (driven by a dict for instance).

Some posters have mentioned speed of operation. Speed of Run-time is secondary for me since if you need speed of execution Python is not the best language to use. I use Python as its the efficiency of coding (i.e. writing error free code) that matters to me.

There are many ways to achieve this but the easiest way in Python 3.6+, in my opinion, is this:

print(f"{1:03}")

use:

<input type="image" src=".."/>

or:

<button type="send"><img src=".."/> + any html code</button>

plus some CSS

No, there is no nonsense like that. Something we have not missed in Python for 20 years.

One approach is to combine the search strings into a regex pattern as in this answer.

It means it's a decimal literal, as others have said. However, the origins are probably not those suggested elsewhere in this answer. From the C# Annotated Standard (the ECMA version, not the MS version):

The decimal suffix is M/m since D/d was already taken by double. Although it has been suggested that M stands for money, Peter Golde recalls that M was chosen simply as the next best letter in decimal.

A similar annotation mentions that early versions of C# included "Y" and "S" for byte and short literals respectively. They were dropped on the grounds of not being useful very often.

This was a pain, using netBeans IDE 7.2.

1. You need to remember that Netbeans cleans up the Build folder whenever you rebuild, so

2. Add a resource folder to the src folder:

   • (project)
     • src
       • project package folder (contains .java files)
       • resources (whatever name you want)
       • images (optional subfolders)

3. After the clean/build this structure is propogated into the Build folder:
   

   • (project)
     
     • build
       
       • classes
         
         • project package folder (contains generated .class files)
           
         • resources (your resources)
           
         • images (your optional subfolders)
           

To access the resources:

dlabel = new JLabel(new ImageIcon(getClass().getClassLoader().getResource("resources/images/logo.png")));

and:

if (common.readFile(getClass().getResourceAsStream("/resources/allwise.ini"), buf).equals("OK")) {

worked for me. Note that in one case there is a leading "/" and in the other there isn't. So the root of the path to the resources is the "classes" folder within the build folder.

Double click on the executable jar file in the dist folder. The path to the resources still works.

You can use -exec to run a command on the output of a command. So it will be a reuse of the output as an example given with a find command below:

find . -name anything.out -exec rm {} \;

you are saying here -> find a file called anything.out in the current folder, if found, remove it. If it is not found, the remaining after -exec will be skipped.

This is useful when you have your own origin which is not upstream. In other words, you might have your own origin repo that you do development and local changes in and then occasionally merge upstream changes. The difference between your example and the highlighted text is that your example assumes you're working with a clone of the upstream repo directly. The highlighted text assumes you're working on a clone of your own repo that was, presumably, originally a clone of upstream.

With Hash::select:

params = params.select { |key, value| /^choice\d+$/.match(key.to_s) }

For SQL Server 2012, using Sql Server Management Studio, I found these steps from the Microsoft page useful to restore to a different database file and name: (ref: http://technet.microsoft.com/en-us/library/ms175510.aspx)

Note steps 4 and 7 are important to set so as not to overwrite the existing database.

To restore a database to a new location, and optionally rename the database

1. Connect to the appropriate instance of the SQL Server Database Engine, and then in Object Explorer, click the server name to expand the server tree.
2. Right-click Databases, and then click Restore Database. The Restore Database dialog box opens.

3. On the General page, use the Source section to specify the source and location of the backup sets to restore. Select one of the following options:

   • Database

     • Select the database to restore from the drop-down list. The list contains only databases that have been backed up according to the msdb backup history.

       Note If the backup is taken from a different server, the destination server will not have the backup history information for the specified database. In this case, select Device to manually specify the file or device to restore.

   • Device

     • Click the browse (...) button to open the Select backup devices dialog box. In the Backup media type box, select one of the listed device types. To select one or more devices for the Backup media box, click Add. After you add the devices you want to the Backup media list box, click OK to return to the General page. In the Source: Device: Database list box, select the name of the database which should be restored.

       Note This list is only available when Device is selected. Only databases that have backups on the selected device will be available.

4. In the Destination section, the Database box is automatically populated with the name of the database to be restored. To change the name of the database, enter the new name in the Database box.
5. In the Restore to box, leave the default as To the last backup taken or click on Timeline to access the Backup Timeline dialog box to manually select a point in time to stop the recovery action.
6. In the Backup sets to restore grid, select the backups to restore. This grid displays the backups available for the specified location. By default, a recovery plan is suggested. To override the suggested recovery plan, you can change the selections in the grid. Backups that depend on the restoration of an earlier backup are automatically deselected when the earlier backup is deselected.
7. To specify the new location of the database files, select the Files page, and then click Relocate all files to folder. Provide a new location for the Data file folder and Log file folder. Alternatively you can keep the same folders and just rename the database and log file names.

Easiest method is to type:

sudo /bin/sh example.sh

how does rails know that user_id is a foreign key referencing user?

Rails itself does not know that user_id is a foreign key referencing user. In the first command rails generate model Micropost user_id:integer it only adds a column user_id however rails does not know the use of the col. You need to manually put the line in the Micropost model

class Micropost < ActiveRecord::Base
  belongs_to :user
end

class User < ActiveRecord::Base
  has_many :microposts
end

the keywords belongs_to and has_many determine the relationship between these models and declare user_id as a foreign key to User model.

The later command rails generate model Micropost user:references adds the line belongs_to :user in the Micropost model and hereby declares as a foreign key.

FYI
Declaring the foreign keys using the former method only lets the Rails know about the relationship the models/tables have. The database is unknown about the relationship. Therefore when you generate the EER Diagrams using software like MySql Workbench you find that there is no relationship threads drawn between the models. Like in the following pic

However, if you use the later method you find that you migration file looks like:

def change
    create_table :microposts do |t|
      t.references :user, index: true

      t.timestamps null: false
    end
    add_foreign_key :microposts, :users

Now the foreign key is set at the database level. and you can generate proper EER diagrams.

Make sure your content is kept in a div, say divfix.

<div id="divfix">Your Code goes here</div>

CSS :

#divfix {
       bottom: 0;
       right: 0;
       position: fixed;
       z-index: 3000;
}

Hope ,It will help you..

Use JSON_UNESCAPED_UNICODE inside json_encode() if your php version >=5.4.

Use Arrow function like this:

<button onClick={()=>{this.handleRemove(id)}}></button>

In our case it turned out that the error happened because we have a custom filter in our application which does HttpServletResponse sendRedirect() to other url.

For some reason, the redirection is not closing the keep-alive status of the connection, hence the timeout exception.

We checked with Tomcat Docs and when we disabled the maxKeepAliveRequests by setting it's value to 1 and the error stopped showing up.

For now we do not have the actual solution to the error.

Loop through the array like any other Associative Array:

while($data = $datas->fetch( PDO::FETCH_ASSOC )){ 
     print $data['title'].'<br>'; 
}

or

$resultset = $datas->fetchALL(PDO::FETCH_ASSOC);

echo '<pre>'.$resultset.'</pre>';

Actually got the same problem. For me worked this easy way:

Adding the data to a Datatable and sort it:

dt.DefaultView.Sort = "columnname";
dt = dt.DefaultView.ToTable();

Update: This solution works and just a call to 'FB.logout()' doesn't work because browser wants a user interaction to actually call this function, so that it knows - it is a user not a script.

<a href="#" onclick="FB.logout();">Logout</a> 

Thought I'd share this code. It's fairly simple, but effective. It parses comma-separated files with parenthesis. You can easily modify it to suit your needs.

There is DatePicker in WPF Tool Kit, but I have not seen DateTime Picker in WPF ToolKit. So I don't know what kind of DateTimePicker control John is talking about.

You can use CURL for this purpose see the example code:

$url = "your url";    
$content = json_encode("your data to be sent");

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
        array("Content-type: application/json"));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);

$json_response = curl_exec($curl);

$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

if ( $status != 201 ) {
    die("Error: call to URL $url failed with status $status, response $json_response, curl_error " . curl_error($curl) . ", curl_errno " . curl_errno($curl));
}


curl_close($curl);

$response = json_decode($json_response, true);

If you're using WordPress, there is now a filter hook to resolve this:

remove_filter('template_redirect', 'redirect_canonical'); 

(Put this in your theme's functions.php)

This tells WordPress to not redirect index.php back to the root page, but to sit where it is. That way, index.html can be assigned to be the default page in .htaccess and can work alongside index.php.

I think the best one-liner is:

pip install --upgrade <package>==<version>

It depends on what you need to do. You can use replace since you want to replace the value:

select replace(email, '.com', '.org')
from yourtable

Then to UPDATE your table with the new ending, then you would use:

update yourtable
set email = replace(email, '.com', '.org')

You can also expand on this by checking the last 4 characters of the email value:

update yourtable
set email = replace(email, '.com', '.org')
where right(email, 4) = '.com'

However, the issue with replace() is that .com can be will in other locations in the email not just the last one. So you might want to use substring() the following way:

update yourtable
set email = substring(email, 1, len(email) -4)+'.org'
where right(email, 4) = '.com';

See SQL Fiddle with Demo

Using substring() will return the start of the email value, without the final .com and then you concatenate the .org to the end. This prevents the replacement of .com elsewhere in the string.

Alternatively you could use stuff(), which allows you to do both deleting and inserting at the same time:

update yourtable
set email = stuff(email, len(email) - 3, 4, '.org')
where right(email, 4) = '.com';

This will delete 4 characters at the position of the third character before the last one (which is the starting position of the final .com) and insert .org instead.

See SQL Fiddle with Demo for this method as well.

You could also use:

<body onload="focusOnInput()">
    <form name="passwordForm" action="verify.php" method="post">
        <input name="passwordInput" type="password" />
    </form>
</body>

And then in your JavaScript:

function focusOnInput() {
    document.forms["passwordForm"]["passwordInput"].focus();
}

This

SELECT CONVERT(NVARCHAR(30), GETDATE(), 126)

will produce this

2009-05-01T14:18:12.430

And some more detail on this can be found at MSDN.

It is the difference between greedy and non-greedy quantifiers.

Consider the input 101000000000100.

Using 1.*1, * is greedy - it will match all the way to the end, and then backtrack until it can match 1, leaving you with 1010000000001.
.*? is non-greedy. * will match nothing, but then will try to match extra characters until it matches 1, eventually matching 101.

All quantifiers have a non-greedy mode: .*?, .+?, .{2,6}?, and even .??.

In your case, a similar pattern could be <([^>]*)> - matching anything but a greater-than sign (strictly speaking, it matches zero or more characters other than > in-between < and >).

See Quantifier Cheat Sheet.

Sure. Just generate a color using random RGB values. Like:

public Color randomColor()
{
  Random random=new Random(); // Probably really put this somewhere where it gets executed only once
  int red=random.nextInt(256);
  int green=random.nextInt(256);
  int blue=random.nextInt(256);
  return new Color(red, green, blue);
}

You might want to vary up the generation of the random numbers if you don't like the colors it comes up with. I'd guess these will tend to be fairly dark.

just want to make a note on the above transitions only need

and -ms- certainly doenst work for IE 9 i dont know where you got that idea from.

Here I have found a solution: https://code.google.com/p/android/issues/detail?id=74772

It is in no way my solution. I have just copied it from there, but I hope it will help someone as much as it helped me when implementing horizontal RecyclerView and wrap_content height (should work also for vertical one and wrap_content width)

The solution is to extend the LayoutManager and override its onMeasure method as @yigit suggested.

Here is the code in case the link dies:

public static class MyLinearLayoutManager extends LinearLayoutManager {

    public MyLinearLayoutManager(Context context) {
        super(context);
    }

    private int[] mMeasuredDimension = new int[2];

    @Override
    public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state,
                          int widthSpec, int heightSpec) {
        final int widthMode = View.MeasureSpec.getMode(widthSpec);
        final int heightMode = View.MeasureSpec.getMode(heightSpec);
        final int widthSize = View.MeasureSpec.getSize(widthSpec);
        final int heightSize = View.MeasureSpec.getSize(heightSpec);

        measureScrapChild(recycler, 0,
                View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
                View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
                mMeasuredDimension);

        int width = mMeasuredDimension[0];
        int height = mMeasuredDimension[1];

        switch (widthMode) {
            case View.MeasureSpec.EXACTLY:
            case View.MeasureSpec.AT_MOST:
                width = widthSize;
                break;
            case View.MeasureSpec.UNSPECIFIED:
        }

        switch (heightMode) {
            case View.MeasureSpec.EXACTLY:
            case View.MeasureSpec.AT_MOST:
                height = heightSize;
                break;
            case View.MeasureSpec.UNSPECIFIED:
        }

        setMeasuredDimension(width, height);
    }

    private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                                   int heightSpec, int[] measuredDimension) {
        View view = recycler.getViewForPosition(position);
        if (view != null) {
            RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();
            int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
                    getPaddingLeft() + getPaddingRight(), p.width);
            int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
                    getPaddingTop() + getPaddingBottom(), p.height);
            view.measure(childWidthSpec, childHeightSpec);
            measuredDimension[0] = view.getMeasuredWidth();
            measuredDimension[1] = view.getMeasuredHeight();
            recycler.recycleView(view);
        }
    }
}

In short, functools.wraps is just a regular function. Let's consider this official example. With the help of the source code, we can see more details about the implementation and the running steps as follows:

1. wraps(f) returns an object, say O1. It is an object of the class Partial
2. The next step is @O1... which is the decorator notation in python. It means

wrapper=O1.__call__(wrapper)

Checking the implementation of __call__, we see that after this step, (the left hand side )wrapper becomes the object resulted by self.func(*self.args, *args, **newkeywords) Checking the creation of O1 in __new__, we know self.func is the function update_wrapper. It uses the parameter *args, the right hand side wrapper, as its 1st parameter. Checking the last step of update_wrapper, one can see the right hand side wrapper is returned, with some of attributes modified as needed.

My personal experience to build website with html, css en javascript is just to stick with plain text editors with ftp support. I am using Espresso or/and Coda on my mac. But Textmate with Cyberduck(ftp client) is also a great combination, imo. For developing in Windows I recommend notepad++.

If there are no typos in the question, you got the conditions wrong:

You said this:

IF cells (i,"A") contains the text 'Miami'

...but your code says:

If Cells(i, "A") <> "Miami"

--> <> means that the value of the cell is not equal to "Miami", so you're not checking what you think you are checking.

I guess you want this instead:

If Cells(i, "A") like "*Miami*"

EDIT:

Sorry, but I can't really help you more. As I already said in a comment, I'm no Excel VBA expert.
Normally I would open Excel now and try your code myself, but I don't even have Excel on any of my machines at home (I use OpenOffice).

Just one general thing: can you identify the row that does not work?
Maybe this helps someone else to answer the question.

Does it ever execute (or at least try to execute) the Cells(i, "C").Value = "BA" line?
Or is the If Cells(i, "A") like "*Miami*" stuff already False?
If yes, try checking just one cell and see if that works.

Your great great great great great great great grandfather should upgrade to SQL Server 2008 and use the DateTime2 data type, which supports dates in the range: 0001-01-01 through 9999-12-31.

Issue:

.Net application code aborts before it starts its execution [Console application or Windows application]

Error received: Aborted with Error code "E0434352"

Exception: Unknown exception

Scenario 1:

When an application is already executed, which have used some of the dependent resources and those resources are still in use with the application executed, when another application or the same exe is triggered from some other source then one of the app throws the error

Scenario 2:

When an application is triggered by scheduler or automatic jobs, it may be in execution state at background, meanwhile when you try to trigger the same application again, the error may be triggered.

Solution:

Create an application, when & where the application release all its resources as soon as completed Kill all the background process once the application is closed Check and avoid executing the application from multiple sources like Batch Process, Task Scheduler and external tools at same time. Check for the Application and resource dependencies and clean up the code if needed.

Optional api provides methods for getting the values. You can check isPresent() for the presence of the value and then make a call to get() or you can make a call to get() chained with orElse() and provide a default value.

The last thing you can try doing is using @Query() over a custom method.

Good questions I have been asked are

• What do you think is good about .NET?
• What do you think is bad about .NET?

It would be interesting to see what a candidate would come up with and you'll certainly learn quite a bit about how he/she uses the framework.

Verify that GenyMotion is in your PATH environment variable. I noticed mine was not auto populated, so once I entered it, it was fine.

The FormClosed Event is an Event that fires when the form closes. It is not used to actually close the form. You'll need to remove anything you've added there.

All you should have to do is add the following line to your button's event handler:

this.Close();

Quick Answer:

foreach (var process in Process.GetProcessesByName("whatever"))
{
    process.Kill();
}

(leave off .exe from process name)

There is no built-in functionality in VBS for that, however, you can use the FileSystemObject FileExists function for that :

Option Explicit
DIM fso    
Set fso = CreateObject("Scripting.FileSystemObject")

If (fso.FileExists("C:\Program Files\conf")) Then
  WScript.Echo("File exists!")
  WScript.Quit()
Else
  WScript.Echo("File does not exist!")
End If

WScript.Quit()

Your code was fine except for the Base 64 encoding bit (which you mentioned was a test), the reason the output may not have made sense is that you were displaying a raw byte array (doing toString() on a byte array returns its internal Java reference, not the String representation of the contents). Here's a version that's just a teeny bit cleaned up and which prints "kyle boon" as the decoded string:

import java.security.MessageDigest;

import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

public class TripleDESTest {

    public static void main(String[] args) throws Exception {

        String text = "kyle boon";

        byte[] codedtext = new TripleDESTest().encrypt(text);
        String decodedtext = new TripleDESTest().decrypt(codedtext);

        System.out.println(codedtext); // this is a byte array, you'll just see a reference to an array
        System.out.println(decodedtext); // This correctly shows "kyle boon"
    }

    public byte[] encrypt(String message) throws Exception {
        final MessageDigest md = MessageDigest.getInstance("md5");
        final byte[] digestOfPassword = md.digest("HG58YZ3CR9"
                .getBytes("utf-8"));
        final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
        for (int j = 0, k = 16; j < 8;) {
            keyBytes[k++] = keyBytes[j++];
        }

        final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
        final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
        final Cipher cipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, key, iv);

        final byte[] plainTextBytes = message.getBytes("utf-8");
        final byte[] cipherText = cipher.doFinal(plainTextBytes);
        // final String encodedCipherText = new sun.misc.BASE64Encoder()
        // .encode(cipherText);

        return cipherText;
    }

    public String decrypt(byte[] message) throws Exception {
        final MessageDigest md = MessageDigest.getInstance("md5");
        final byte[] digestOfPassword = md.digest("HG58YZ3CR9"

        final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
        for (int j = 0, k = 16; j < 8;) {
            keyBytes[k++] = keyBytes[j++];
        }

        final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
        final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
        final Cipher decipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
        decipher.init(Cipher.DECRYPT_MODE, key, iv);

        // final byte[] encData = new
        // sun.misc.BASE64Decoder().decodeBuffer(message);
        final byte[] plainText = decipher.doFinal(message);

        return new String(plainText, "UTF-8");
    }
}

text() and node() are node tests, in XPath terminology (compare).

Node tests operate on a set (on an axis, to be exact) of nodes and return the ones that are of a certain type. When no axis is mentioned, the child axis is assumed by default.

There are all kinds of node tests:

• node() matches any node (the least specific node test of them all)
• text() matches text nodes only
• comment() matches comment nodes
• * matches any element node
• foo matches any element node named "foo"
• processing-instruction() matches PI nodes (they look like <?name value?>).
• Side note: The * also matches attribute nodes, but only along the attribute axis. @* is a shorthand for attribute::*. Attributes are not part of the child axis, that's why a normal * does not select them.

This XML document:

<produce>
    <item>apple</item>
    <item>banana</item>
    <item>pepper</item>
</produce>

represents the following DOM (simplified):

root node
   element node (name="produce")
      text node (value="\n    ")
      element node (name="item")
         text node (value="apple")
      text node (value="\n    ")
      element node (name="item")
         text node (value="banana")
      text node (value="\n    ")
      element node (name="item")
         text node (value="pepper")
      text node (value="\n")

So with XPath:

• / selects the root node
• /produce selects a child element of the root node if it has the name "produce" (This is called the document element; it represents the document itself. Document element and root node are often confused, but they are not the same thing.)
• /produce/node() selects any type of child node beneath /produce/ (i.e. all 7 children)
• /produce/text() selects the 4 (!) whitespace-only text nodes
• /produce/item[1] selects the first child element named "item"
• /produce/item[1]/text() selects all child text nodes (there's only one - "apple" - in this case)

And so on.

So, your questions

• "Select the text of all items under produce" /produce/item/text() (3 nodes selected)
• "Select all the manager nodes in all departments" //department/manager (1 node selected)

Notes

• The default axis in XPath is the child axis. You can change the axis by prefixing a different axis name. For example: //item/ancestor::produce
• Element nodes have text values. When you evaluate an element node, its textual contents will be returned. In case of this example, /produce/item[1]/text() and string(/produce/item[1]) will be the same.
• Also see this answer where I outline the individual parts of an XPath expression graphically.

You need to call attemptRotationToDeviceOrientation (UIViewController) to make the system call your supportedInterfaceOrientations when the condition has changed.

It's been solved.

The losses only save to the History over the epochs. I was running iterations instead of using the Keras built in epochs option.

so instead of doing 4 iterations I now have

model.fit(......, nb_epoch = 4)

Now it returns the loss for each epoch run:

print(hist.history)
{'loss': [1.4358016599558268, 1.399221191623641, 1.381293383180471, h1.3758836857303727]}

• ^ matches position just before the first character of the string
• $ matches position just after the last character of the string
• . matches a single character. Does not matter what character it is, except newline
• * matches preceding match zero or more times

So, ^.*$ means - match, from beginning to end, any character that appears zero or more times. Basically, that means - match everything from start to end of the string. This regex pattern is not very useful.

Let's take a regex pattern that may be a bit useful. Let's say I have two strings The bat of Matt Jones and Matthew's last name is Jones. The pattern ^Matt.*Jones$ will match Matthew's last name is Jones. Why? The pattern says - the string should start with Matt and end with Jones and there can be zero or more characters (any characters) in between them.

Feel free to use an online tool like https://regex101.com/ to test out regex patterns and strings.

The one that got me was similar to the other poster's "tbl" prefix for SQL table names.

In this case, the prefix for all stored procedures was to be "sp_" despite the fact that "sp_" is a prefix used by Microsoft for system-level stored procedures in SQL Server. Well, they had their standards from an old, non-MS database and weren't about to change just because their standard might cause a stored procedure to collide with a system stored procedure and produce unpredictable results. No, that just wouldn't be proper.

There are basically two major pitfalls people stumble in with floating-point numbers.

1. The problem of scale. Each FP number has an exponent which determines the overall “scale” of the number so you can represent either really small values or really larges ones, though the number of digits you can devote for that is limited. Adding two numbers of different scale will sometimes result in the smaller one being “eaten” since there is no way to fit it into the larger scale.

   PS> $a = 1; $b = 0.0000000000000000000000001
   PS> Write-Host a=$a b=$b
   a=1 b=1E-25
   PS> $a + $b
   1
   

   As an analogy for this case you could picture a large swimming pool and a teaspoon of water. Both are of very different sizes, but individually you can easily grasp how much they roughly are. Pouring the teaspoon into the swimming pool, however, will leave you still with roughly a swimming pool full of water.

   (If the people learning this have trouble with exponential notation, one can also use the values 1 and 100000000000000000000 or so.)

2. Then there is the problem of binary vs. decimal representation. A number like 0.1 can't be represented exactly with a limited amount of binary digits. Some languages mask this, though:

   PS> "{0:N50}" -f 0.1
   0.10000000000000000000000000000000000000000000000000
   

   But you can “amplify” the representation error by repeatedly adding the numbers together:

   PS> $sum = 0; for ($i = 0; $i -lt 100; $i++) { $sum += 0.1 }; $sum
   9,99999999999998
   

   I can't think of a nice analogy to properly explain this, though. It's basically the same problem why you can represent ¹/₃ only approximately in decimal because to get the exact value you need to repeat the 3 indefinitely at the end of the decimal fraction.

   Similarly, binary fractions are good for representing halves, quarters, eighths, etc. but things like a tenth will yield an infinitely repeating stream of binary digits.

3. Then there is another problem, though most people don't stumble into that, unless they're doing huge amounts of numerical stuff. But then, those already know about the problem. Since many floating-point numbers are merely approximations of the exact value this means that for a given approximation f of a real number r there can be infinitely many more real numbers r₁, r₂, ... which map to exactly the same approximation. Those numbers lie in a certain interval. Let's say that r_min is the minimum possible value of r that results in f and r_max the maximum possible value of r for which this holds, then you got an interval [r_min, r_max] where any number in that interval can be your actual number r.

   Now, if you perform calculations on that number—adding, subtracting, multiplying, etc.—you lose precision. Every number is just an approximation, therefore you're actually performing calculations with intervals. The result is an interval too and the approximation error only ever gets larger, thereby widening the interval. You may get back a single number from that calculation. But that's merely one number from the interval of possible results, taking into account precision of your original operands and the precision loss due to the calculation.

   That sort of thing is called Interval arithmetic and at least for me it was part of our math course at the university.

Even though this is pretty old, just chiming in to say that what is useful in @Sidupac's answer is the FOREIGN_KEY_CHECKS=0.

This answer is not an option when you are using something that manages the database schema for you (JPA in my case) but the problem may be that there are "orphaned" entries in your table (referencing a foreign key that might not exist).

This can often happen when you convert a MySQL table from MyISAM to InnoDB since referential integrity isn't really a thing with the former.

As already said by Jordão, just negate it:

if (!(id in tutorTimes)) { ... }

Note: The above test if tutorTimes has a property with the name specified in id, anywhere in the prototype chain. For example "valueOf" in tutorTimes returns true because it is defined in Object.prototype.

If you want to test if a property doesn't exist in the current object, use hasOwnProperty:

if (!tutorTimes.hasOwnProperty(id)) { ... }

Or if you might have a key that is hasOwnPropery you can use this:

if (!Object.prototype.hasOwnProperty.call(tutorTimes,id)) { ... }

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

You can read the full documentation here.

The list method index will return -1 if the item is not present, and will return the index of the item in the list if it is present. Alternatively in an if statement you can do the following:

if myItem in list:
    #do things

You can also check if an element is not in a list with the following if statement:

if myItem not in list:
    #do things

I don't think that using regular expressions is a smart thing to do in this case. It is impossible to match all of the possibilities and even if you did, there is still a chance that url simply doesn't exist.

Here is a very simple way to test if url actually exists and is readable :

if (preg_match("#^https?://.+#", $link) and @fopen($link,"r")) echo "OK";

(if there is no preg_match then this would also validate all filenames on your server)

It took a while to put together a solution for this, but have found this is the easiest way to get it to work in the way that you describe. There could be better ways to do this, but since you haven't posted your activity code I will have to improvise and assume you have a list like this at the start of your activity:

private List<String> items = db.getItems();

ExampleActivity.java

private List<String> items;

private Menu menu;

@Override
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.example, menu);

    this.menu = menu;

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));

        search.setOnQueryTextListener(new OnQueryTextListener() { 

            @Override 
            public boolean onQueryTextChange(String query) {

                loadHistory(query);

                return true; 

            } 

        });

    }

    return true;

}

// History
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void loadHistory(String query) {

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        // Cursor
        String[] columns = new String[] { "_id", "text" };
        Object[] temp = new Object[] { 0, "default" };

        MatrixCursor cursor = new MatrixCursor(columns);

        for(int i = 0; i < items.size(); i++) {

            temp[0] = i;
            temp[1] = items.get(i);

            cursor.addRow(temp);

        }

        // SearchView
        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        final SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSuggestionsAdapter(new ExampleAdapter(this, cursor, items));

    }

}

Now you need to create an adapter extended from CursorAdapter:

ExampleAdapter.java

public class ExampleAdapter extends CursorAdapter {

    private List<String> items;

    private TextView text;

    public ExampleAdapter(Context context, Cursor cursor, List<String> items) {

        super(context, cursor, false);

        this.items = items;

    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {

        text.setText(items.get(cursor.getPosition()));

    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View view = inflater.inflate(R.layout.item, parent, false);

        text = (TextView) view.findViewById(R.id.text);

        return view;

    }

}

A better way to do this is if your list data is from a database, you can pass the Cursor returned by database functions directly to ExampleAdapter and use the relevant column selector to display the column text in the TextView referenced in the adapter.

Please note: when you import CursorAdapter don't import the Android support version, import the standard android.widget.CursorAdapter instead.

The adapter will also require a custom layout:

res/layout/item.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView
        android:id="@+id/item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</RelativeLayout>

You can now customize list items by adding additional text or image views to the layout and populating them with data in the adapter.

This should be all, but if you haven't done this already you need a SearchView menu item:

res/menu/example.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/search"
        android:title="@string/search"
        android:showAsAction="ifRoom"
        android:actionViewClass="android.widget.SearchView" />

</menu>

Then create a searchable configuration:

res/xml/searchable.xml

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/search"
    android:hint="@string/search" >
</searchable>

Finally add this inside the relevant activity tag in the manifest file:

AndroidManifest.xml

<intent-filter>
    <action android:name="android.intent.action.SEARCH" />
</intent-filter>

<meta-data
    android:name="android.app.default_searchable"
    android:value="com.example.ExampleActivity" />
<meta-data
    android:name="android.app.searchable"
    android:resource="@xml/searchable" />

Please note: The @string/search string used in the examples should be defined in values/strings.xml, also don't forget to update the reference to com.example for your project.

In case the accepted answer by Wadih didn't work for you, try echo %CD%

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:

$('a#check_var').click(function() {
  alert($("input:radio[name='r']:checked").val()+ ' '+
        $("input:radio[name='s']:checked").val());
});?

You can see the working version here.

using timedeltas you can do:

import datetime
today=datetime.date.today()


time=datetime.time()
print("today :",today)

# One day different .
five_day=datetime.timedelta(days=5)
print("one day :",five_day)
#output - 1 day , 00:00:00


# five day extend .
fitfthday=today+five_day
print("fitfthday",fitfthday)


# five day extend .
fitfthday=today+five_day
print("fitfthday",fitfthday)
#output - 
today : 2019-05-29
one day : 5 days, 0:00:00
fitfthday 2019-06-03

I ran into this problem with Tomcat. Setting the following in $CATALINA_BASE/bin/setenv.sh solved the issue:

JAVA_OPTS=-Doracle.jdbc.timezoneAsRegion=false

I'm sure that using one of the Java parameter suggestions from the other answers would work in the same way.

Try this:

$("#autoship_option option[selected]").removeAttr("selected");

I found this to be the best way of doing this (I had an issue with my server not letting me delete).

On the server that hosts the origin repository, type the following from a directory inside the repository:

git config receive.denyDeleteCurrent ignore

On your workstation:

git branch -m master vabandoned                 # Rename master on local
git branch -m newBranch master                  # Locally rename branch newBranch to master
git push origin :master                         # Delete the remote's master
git push origin master:refs/heads/master        # Push the new master to the remote
git push origin abandoned:refs/heads/abandoned  # Push the old master to the remote

Back on the server that hosts the origin repository:

git config receive.denyDeleteCurrent true

Add your user to Sharing & Permissions. Read & Write Permissions.

And go to terminal and run npm install -g @ionic/cli

It has helped me.

For the current branch, you could also say git checkout (w/o any branch). This is a no-op with a side-effects to show the tracking information, if exists, for the current branch.

$ git checkout 
Your branch is up-to-date with 'origin/master'.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
    CookieManager.getInstance().removeAllCookies(null);
    CookieManager.getInstance().flush();
} 

Take a look at the Maven dependency plugin, specifically, the dependency:copy-dependencies goal. Take a look at the example under the heading The dependency:copy-dependencies mojo. Set the outputDirectory configuration property to ${basedir}/target/lib (I believe, you'll have to test).

Hope this helps.

Although :pastetoggle or :paste and :nopaste should be working fine (if implemented - they are not always as we can see from the discussion) I highly recomment pasting using the direct approach "+p or "*p and reading with "+r or "*r:

Vim has acess to ten types of registers (:help registers) and the questioner is interested in quotestar and quoteplus from section

8. Selection and drop registers "*, "+ and "~

Use these registers for storing and retrieving the selected text for the GUI. See quotestar and quoteplus. When the clipboard is not available or not working, the unnamed register is used instead. For Unix systems the clipboard is only available when the +xterm_clipboard feature is present. {not in Vi}

Note that there is only a distinction between "* and "+ for X11 systems.

:help x11-selection further clarifies the difference of * and +:

                                                  quoteplus quote+

There are three documented X selections: PRIMARY (which is expected to represent the current visual selection - as in Vim's Visual mode), SECONDARY (which is ill-defined) and CLIPBOARD (which is expected to be used for cut, copy and paste operations).

Of these three, Vim uses PRIMARY when reading and writing the "* register (hence when the X11 selections are available, Vim sets a default value for 'clipboard' of "autoselect"), and CLIPBOARD when reading and writing the "+ register. Vim does not access the SECONDARY selection.

Examples: (assuming the default option values)

• Select an URL in Visual mode in Vim. Go to your browser and click the middle mouse button in the URL text field. The selected text will be inserted (hopefully!). Note: in Firefox you can set the middlemouse.contentLoadURL preference to true in about:config, then the selected URL will be used when pressing middle mouse button in most places in the window.

• Select some text in your browser by dragging with the mouse. Go to Vim and press the middle mouse button: The selected text is inserted.

• Select some text in Vim and do "+y. Go to your browser, select some text in a textfield by dragging with the mouse. Now use the right mouse button and select "Paste" from the popup menu. The selected text is overwritten by the text from Vim. Note that the text in the "+ register remains available when making a Visual selection, which makes other text available in the "* register. That allows overwriting selected text.

It is generally not a bad idea to avoid the !-operator if you have the choice. One simple reason is that it can be a source of errors, because it is possible to overlook it. More readable can be: if(conditionA==false) in some cases. This mainly plays a role if you skip the else part. If you have an else-block anyway you should not use the negation in the if-condition.

Except for composed-conditions like this:

if(!isA() && isB() && !isNotC())

Here you have to use some sort of negation to get the desired logic. In this case, what really is worth thinking about is the naming of the functions or variables. Try to name them so you can often use them in simple conditions without negation.

In this case you should think about the logic of isNotC() and if it could be replaced by a method isC() if it makes sense.

Finally your example has another problem when it comes to readability which is even more serious than the question whether to use negation or not: Does the reader of the code really knows when doSomething() returns true and when false? If it was false was it done anyway? This is a very common problem, which ends in the reader trying to find out what the return values of functions really mean.

When you #include a header, it's exactly as if you put the code into the source file itself. In both cases the varGlobal variable is defined in the source so it will work no matter how it's declared.

Also as pointed out in the comments, C++ variables at file scope are not static in scope even though they will be assigned to static storage. If the variable were a class member for example, it would need to be accessible to other compilation units in the program by default and non-class members are no different.

Documentation of Math.round says:

Returns the result of rounding the argument to an integer. The result is equivalent to (int) Math.floor(f+0.5).

No need to cast to int. Maybe it was changed from the past.

I generally prefer, where possible, to use the default value of value types to determine whether they've been set. This obviously isn't possible all the time, especially with ints - but for DateTimes, I think reserving the MinValue to signify that it hasn't been changed is fair enough. The benefit of this over nullables is that there's one less place where you'll get a null reference exception (and probably lots of places where you don't have to check for null before accessing it!)

Just use a specific variable for that.

$ cat Makefile 
all:
    echo foo | gcc $(USER_DEFINES) -E -xc - 

$ make USER_DEFINES="-Dfoo=one"
echo foo | gcc -Dfoo=one -E -xc - 
...
one

$ make USER_DEFINES="-Dfoo=bar"
echo foo | gcc -Dfoo=bar -E -xc - 
...
bar

$ make 
echo foo | gcc  -E -xc - 
...
foo

Use cssText

nFilter.style.cssText +=';width:330px;float:left;';

Use trim and val.

var value=$.trim($("#spa").val());

if(value.length>0)
{
 //do some stuffs. 
}

val() : return the value of the input.

trim(): will trim the white spaces.

Have you tried using the 'static' storage class similar to?:

public static class employee
{
    static NameValueCollection appSetting = ConfigurationManager.AppSettings;    
}

SELECT variant (not creating a user defined function):

SELECT IF(
        LOCATE(' ', `membername`) > 0,
        SUBSTRING(`membername`, 1, LOCATE(' ', `membername`) - 1),
        `membername`
    ) AS memberfirst,
    IF(
        LOCATE(' ', `membername`) > 0,
        SUBSTRING(`membername`, LOCATE(' ', `membername`) + 1),
        NULL
    ) AS memberlast
FROM `user`;

This approach also takes care of:

• membername values without a space: it will add the whole string to memberfirst and sets memberlast to NULL.
• membername values that have multiple spaces: it will add everything before the first space to memberfirst and the remainder (including additional spaces) to memberlast.

The UPDATE version would be:

UPDATE `user` SET
    `memberfirst` = IF(
        LOCATE(' ', `membername`) > 0,
        SUBSTRING(`membername`, 1, LOCATE(' ', `membername`) - 1),
        `membername`
    ),
    `memberlast` = IF(
        LOCATE(' ', `membername`) > 0,
        SUBSTRING(`membername`, LOCATE(' ', `membername`) + 1),
        NULL
    );

There are four ways to do this as I know

const array = [{id:1,name:'Jim'},{id:2,name:'Parker'}];
const toDelete = 1;

The first:

_.reject(array, {id:toDelete})

The second one is :

_.remove(array, {id:toDelete})

In this way the array will be mutated.

The third one is :

_.differenceBy(array,[{id:toDelete}],'id')
// If you can get remove item 
// _.differenceWith(array,[removeItem])

The last one is:

_.filter(array,({id})=>id!==toDelete)

Answer to make a record, so that I can find it later.

If the files which you are loading are cached and if the changes you have made does not reflect in the code then there are 2 ways you can deal with this

1. Clear the Cache as everyone told

2. If u want Cache and only the files have to be reloaded , you can go to network tab of the dev tool and clear whatever was loaded. next time it will not load it from cache. you will have your latest changes.

Whilst this is counter intuitive this is the way that i sped up this operation by a huge amount.

Exactly what i was doing:

ArrayList < HashMap < String , String >> results; // This has been filled with a whole bunch of results

ArrayList < HashMap < String , String > > discard = findResultsToDiscard(results);

results.removeall(discard);

However the remove all method was taking upwards of 6 seconds (NOT including the method to get the discard results) to remove approximately 800 results from an array of 2000 (ish).

I tried the iterator method suggested by gustafc and others on this post.

This did speed up the operation slightly (down to about 4 seconds) however this was still not good enough. So i tried something risky...

 ArrayList < HashMap < String, String>> results;

  List < Integer > noIndex = getTheDiscardedIndexs(results);

for (int j = noIndex.size()-1; j >= 0; j-- ){
    results.remove(noIndex.get(j).intValue());
}

whilst the getTheDiscardedIndexs save an array of index's rather then an array of HashMaps. This it turns out sped up removing objects much quicker ( about 0.1 of a second now) and will be more memory efficient as we dont need to create a large array of results to remove.

Hope this helps someone.

On Windows 8 I was batteling with this for some time:

On my blog, the reason of this error is a plugin named Broken Link checker. This plugin has high resource usage from hosting, resulting in this error.

Check if a plugin on your installation is behaving similarly like this.

Maybe you need unique temporary file?

import tempfile

f = tempfile.NamedTemporaryFile(mode='w+b', delete=False)

print f.name
f.close()

f is opened file. delete=False means do not delete file after closing.

If you need control over the name of the file, there are optional prefix=... and suffix=... arguments that take strings. See https://docs.python.org/3/library/tempfile.html.

Although I almost always just use pandas for this, my current little tool is being packaged into an executable and including pandas is overkill. So I created a version of poida's solution that resulted in a list of named tuples. His code with this change would look like this:

from xlrd import open_workbook
from collections import namedtuple
from pprint import pprint

wb = open_workbook('sample.xls')

FORMAT = ['Arm_id', 'DSPName', 'PinCode']
OneRow = namedtuple('OneRow', ' '.join(FORMAT))
all_rows = []

for s in wb.sheets():
    headerRow = s.row(0)
    columnIndex = [x for y in FORMAT for x in range(len(headerRow)) if y == headerRow[x].value]

    for row in range(1,s.nrows):
        currentRow = s.row(row)
        currentRowValues = [currentRow[x].value for x in columnIndex]
        all_rows.append(OneRow(*currentRowValues))

pprint(all_rows)

You can access variables to any class without creating objects, if its extended by Application. They can be called globally and their state is maintained till application is not killed.

If you have a _Layout.cshtml view like this

<html>
    <body>
        @RenderBody()
        @RenderSection("scripts", required: false)
    </body>
</html>

then you can have an index.cshtml content view like this

@section scripts {
     <script type="text/javascript">alert('hello');</script>
}

the required indicates whether or not the view using the layout page must have a scripts section

In MongoDB 3.2 and newer, Mongo().getDBNames() in the mongo shell will output a list of database names in the server:

> Mongo().getDBNames()
[ "local", "test", "test2", "test3" ]

> show dbs
local  0.000GB
test   0.000GB
test2  0.000GB
test3  0.000GB

A forEach() loop over the array could then call dropDatabase() to drop all the listed databases. Optionally you can opt to skip some important databases that you don't want to drop. For example:

Mongo().getDBNames().forEach(function(x) {
  // Loop through all database names
  if (['admin', 'config', 'local'].indexOf(x) < 0) {
    // Drop if database is not admin, config, or local
    Mongo().getDB(x).dropDatabase();
  }
})

Example run:

> show dbs
admin   0.000GB
config  0.000GB
local   0.000GB
test    0.000GB
test2   0.000GB
test3   0.000GB

> Mongo().getDBNames().forEach(function(x) {
...   if (['admin', 'config', 'local'].indexOf(x) < 0) {
...     Mongo().getDB(x).dropDatabase();
...   }
... })

> show dbs
admin   0.000GB
config  0.000GB
local   0.000GB

I like to see a green tick in the top right corner in PyCharm. I append the variable names with an underscore just to clear this warning so I can focus on the important warnings.

To keep open your windows console and to not use other output methods rather than the standard output stream cout go to Name-of-your-project -> Properties -> Linker -> System.

Once there, select the SubSytem Tab and mark Console (/SUBSYSTEM:CONSOLE). Once you have done this, whenever you want to compile use Ctrl + F5 (Start without debugging) and your console will keep opened. :)

You can modify .htaccess like others said, but the fastest solution is to rename the file extension to .php

Implementation of seconds/minutes/hours, which are rails methods. Note that implicit returns aren't needed, but they look cleaner, so I prefer them. I'm not sure Rails even has .days or if it goes further, but these are the ones I need.

class Integer
   def seconds
      return self
   end
   def minutes
      return self * 60
   end
   def hours
      return self * 3600
   end
   def days
      return self * 86400
   end
end

After this, you can do: sleep 5.seconds to sleep for 5 seconds. You can do sleep 5.minutes to sleep for 5 min. You can do sleep 5.hours to sleep for 5 hours. And finally, you can do sleep 5.days to sleep for 5 days... You can add any method that return the value of self * (amount of seconds in that timeframe). As an exercise, try implementing it for months!

This error occurred in my application with the CIP-protocol whenever I didn't Send or received data in less than 10s.

This was caused by the use of the forward open method. You can avoid this by working with an other method, or to install an update rate of less the 10s that maintain your forward-open-connection.

Since curl 7.67.0 (2019-11-06) there is --no-progress-meter, which does exactly this, and nothing else. From the man page:

   --no-progress-meter
         Option to switch off the progress meter output without muting or
         otherwise affecting warning and informational messages like  -s,
         --silent does.

         Note  that  this  is the negated option name documented. You can
         thus use --progress-meter to enable the progress meter again.

         See also -v, --verbose and -s, --silent. Added in 7.67.0.

It's available in Ubuntu =20.04 and Debian =11 (Bullseye).

For a bit of history on curl's verbosity options, you can read Daniel Stenberg's blog post.

For new you should use delete. For new[] use delete[]. Your second variant is correct.

I have used a trick to handle the apostrophe special character. When replacing ' for \' you need to place four backslashes before the apostrophe.

str.replaceAll("'","\\\\'");

this has been modified in codeigniter 2.2.1...usually not best practice to modify core files, I would always check for updates and 2.2.1 came out in Jan 2015

Try this instead:

var myArray = [];

myArray.push({ id: 0, value: 1 });
myArray.push({ id: 2, value: 3 });

or will this not work for your situation?

The easiest way is to make the "button image" as a separate image. Then place it over the main image (using "style="position: absolute;". Assign the URL link to "button image". and smile :)

Remove Columns For RAILS 5 App

I have another one with BOX-SHADOW

here it is JSFIDDLE

and the code

nav {
    margin:0px auto;
    width:100%;
    height:50px;
    background-color:grey;
    float:left;
    padding:10px;
    border:2px solid red;
    box-shadow: 0 0 0 10px blue inset;
}

it also support in IE9, so It's better than gradient solution, add proper prefixes for more support

IE8 dont support it, what a shame !

It looks like the string contains an array with a single MyStok object in it. If you remove square brackets from both ends of the input, you should be able to deserialize the data as a single object:

MyStok myobj = JSON.Deserialize<MyStok>(sc.Substring(1, sc.Length-2));

You could also deserialize the array into a list of MyStok objects, and take the object at index zero.

var myobjList = JSON.Deserialize<List<MyStok>>(sc);
var myObj = myobjList[0];

I had this issue and none of the short answers here worked, even in the page mentioned by @tudor above. I thought I would share here how I got rid of the images. I came up with the idea that dependent images must be >= the size of the parent image, which helps identify it so we can remove it.

I listed the images in size order to see if I could spot any correlations:

docker images --format '{{.Size}}\t{{.Repository}}\t{{.Tag}}\t{{.ID}}' | sort -h -r | column -t

What this does, is use some special formatting from docker to position the image size column first, then run a human readable sort in reverse order. Then I restore the easy-to-read columns.

Then I looked at the <none> containers, and matched the first one in the list with a similar size. I performed a simple docker rmi <image:tag> on that image and all the <none> child images went with it.

The problem image with all the child images was actually the damn myrepo/getstarted-lab image I used when I first started playing with docker. It was because I had created a new image from the first test image which created the chain.

Hopefully that helps someone else at some point.

        for chunk in iter(lambda: f.read(128 * md5.block_size), b''):
            md5.update(chunk)
    return md5.hexdigest()

//The simple version for 10 Characters from the beginning of the string
$string = substr($string,0,10).'...';

Update:

Based on suggestion for checking length (and also ensuring similar lengths on trimmed and untrimmed strings):

$string = (strlen($string) > 13) ? substr($string,0,10).'...' : $string;

So you will get a string of max 13 characters; either 13 (or less) normal characters or 10 characters followed by '...'

Update 2:

Or as function:

function truncate($string, $length, $dots = "...") {
    return (strlen($string) > $length) ? substr($string, 0, $length - strlen($dots)) . $dots : $string;
}

Update 3:

It's been a while since I wrote this answer and I don't actually use this code any more. I prefer this function which prevents breaking the string in the middle of a word using the wordwrap function:

function truncate($string,$length=100,$append="…") {
  $string = trim($string);

  if(strlen($string) > $length) {
    $string = wordwrap($string, $length);
    $string = explode("\n", $string, 2);
    $string = $string[0] . $append;
  }

  return $string;
}

In addition to the provided answer, there are more details to navigate. From the function's comments:

/**
 * Navigate based on the provided array of commands and a starting point.
 * If no starting route is provided, the navigation is absolute.
 *
 * Returns a promise that:
 * - resolves to 'true' when navigation succeeds,
 * - resolves to 'false' when navigation fails,
 * - is rejected when an error happens.
 *
 * ### Usage
 *
 * ```
 * router.navigate(['team', 33, 'user', 11], {relativeTo: route});
 *
 * // Navigate without updating the URL
 * router.navigate(['team', 33, 'user', 11], {relativeTo: route, skipLocationChange: true});
 * ```
 *
 * In opposite to `navigateByUrl`, `navigate` always takes a delta that is applied to the current
 * URL.
 */

The Router Guide has more details on programmatic navigation.

PrincipalContext for browsing the AD is ridiculously slow (only use it for .ValidateCredentials, see below), use DirectoryEntry instead and .PropertiesToLoad() so you only pay for what you need.

Filters and syntax here: https://social.technet.microsoft.com/wiki/contents/articles/5392.active-directory-ldap-syntax-filters.aspx

Attributes here: https://docs.microsoft.com/en-us/windows/win32/adschema/attributes-all

using (var root = new DirectoryEntry($"LDAP://{Domain}"))
{
    using (var searcher = new DirectorySearcher(root))
    {
        // looking for a specific user
        searcher.Filter = $"(&(objectCategory=person)(objectClass=user)(sAMAccountName={username}))";
        // I only care about what groups the user is a memberOf
        searcher.PropertiesToLoad.Add("memberOf");

        // FYI, non-null results means the user was found
        var results = searcher.FindOne();

        var properties = results?.Properties;
        if (properties?.Contains("memberOf") == true)
        {
            // ... iterate over all the groups the user is a member of
        }
    }
}

Clean, simple, fast. No magic, no half-documented calls to .RefreshCache to grab the tokenGroups or to .Bind or .NativeObject in a try/catch to validate credentials.

For authenticating the user:

using (var context = new PrincipalContext(ContextType.Domain))
{
    return context.ValidateCredentials(username, password);
}

You need to detect the click from js side, your HTML remaining same. Note: this method is deprecated since v3.5.5 and removed in v4.

$("button").click(function() {
    var $btn = $(this);
    $btn.button('loading');
    // simulating a timeout
    setTimeout(function () {
        $btn.button('reset');
    }, 1000);
});

Also, don't forget to load jQuery and Bootstrap js (based on jQuery) file in your page.

All the above solutions work fine.

It will create issues when there are any special characters in your environment variable.

I have found the solution:

eval $(printenv | awk -F= '{print "export " "\""$1"\"""=""\""$2"\"" }' >> /etc/profile)

If it is because of the overhead in terms of creating objects, then it probably can't be sped up at all with SA.

If it is because it is loading up related objects, then you might be able to do something with lazy loading. Are there lots of objects being created due to references? (IE, getting a Company object also gets all of the related People objects).

One other way around this is to use @Mock annotation instead. Doesn't work in all cases, but looks much sexier :)

Here's an example:

@RunWith(MockitoJUnitRunner.class)
public class FooTests {

    @Mock
    public Foo<Bar> fooMock;

    @Test
    public void testFoo() {
        when(fooMock.getValue()).thenReturn(new Bar());
    }
}

The MockitoJUnitRunner initializes the fields annotated with @Mock.

Position your <div> absolutely at the bottom and don't forget to give div.A a position: relative - http://jsfiddle.net/TTaMx/

    .A {
        position: relative;
        margin: 40px 0;
        height: 40px;
        width: 200px;
        background: #eee;
    }

    .A:after {
        content: " ";
        display: block;
        background: #c00;
        height: 29px;
        width: 100%;

        position: absolute;
        bottom: -29px;
    }?

You can use jQuery.post() and return nicely structured JSON answers from server. It also allows you to validate/sanitize your data directly on server, which is a good practice because it's more secure (and even easier) than doing this on client.

For example if you need to post html form to server (to saveprofilechanges.php) with user data for simple registration:

I. Client parts:

I.a. HTML part:

<form id="user_profile_form">
  <label for="first_name"><input type="text" name="first_name" id="first_name" required />First name</label>
  <label for="family_name"><input type="text" name="family_name" id="family_name" required />Family name</label>
  <label for="email"><input type="email" name="email" id="email" required />Email</label> 
  <input type="submit" value="Save changes" id="submit" />
</form>

I.b. Script part:

$(function () {
    $("#user_profile_form").submit(function(event) {
      event.preventDefault();
      var postData = {
        first_name: $('#first_name').val(),
        family_name: $('#family_name').val(),
        email: $('#email').val()
      };
      $.post("/saveprofilechanges.php", postData,
        function(data) {
          var json = jQuery.parseJSON(data);
          if (json.ExceptionMessage != undefined) {
            alert(json.ExceptionMessage); // the exception from the server
            $('#' + json.Field).focus(); // focus the specific field to fill in
          }
          if (json.SuccessMessage != undefined) {
            alert(json.SuccessMessage); // the success message from server
          }
       });
    });
});

II. Server part (saveprofilechanges.php):

$data = $_POST;
if (!empty($data) && is_array($data)) {
    // Some data validation:
    if (empty($data['first_name']) || !preg_match("/^[a-zA-Z]*$/", $data['first_name'])) {
       echo json_encode(array(
         'ExceptionMessage' => "First name missing or incorrect (only letters and spaces allowed).",
         'Field' => 'first_name' // Form field to focus in client form
       ));
       return FALSE;
    }
    if (empty($data['family_name']) || !preg_match("/^[a-zA-Z ]*$/", $data['family_name'])) {
       echo json_encode(array(
         'ExceptionMessage' => "Family name missing or incorrect (only letters and spaces allowed).",
         'Field' => 'family_name' // Form field to focus in client form
       ));
       return FALSE;
    }
    if (empty($data['email']) || !filter_var($data['email'], FILTER_VALIDATE_EMAIL)) {
       echo json_encode(array(
         'ExceptionMessage' => "Email missing or incorrectly formatted. Please enter it again.",
         'Field' => 'email' // Form field to focus in client form
       ));
       return FALSE;
    }
    // more actions..
    // more actions..
    try {
       // Some save to database or other action..:
       $this->User->update($data, array('username=?' => $username));
       echo json_encode(array(
         'SuccessMessage' => "Data saved!"
       ));
       return TRUE;
    } catch (Exception $e) {
       echo json_encode(array(
         'ExceptionMessage' => $e->getMessage()
       ));
       return FALSE;
    }
}

The problem is your plugin. To solve this is to only enter this address:

chrome://flags/#enable-NPAPI

Click activate NPAPI, and finally restart at the bottom of the page.

From the documentation, you can apparently use either command to keep the file in the project history. Looks like you want remove, since it also deletes the file from the working directory.

From the Mercurial book at http://hgbook.red-bean.com/read/:

Removing a file does not affect its history. It is important to understand that removing a file has only two effects. It removes the current version of the file from the working directory. It stops Mercurial from tracking changes to the file, from the time of the next commit. Removing a file does not in any way alter the history of the file.

The man page hg(1) says this about forget:

Mark the specified files so they will no longer be tracked after the next commit. This only removes files from the current branch, not from the entire project history, and it does not delete them from the working directory.

And this about remove:

Schedule the indicated files for removal from the repository. This only removes files from the current branch, not from the entire project history.

Bootstrap 4 provides standard methods for this, fully described here: https://getbootstrap.com/docs/4.3/getting-started/theming

Eg. you can override defaults simply by setting variables in the SASS file, where you import bootstrap. An example from the docs (which also answers the question):

// Your variable overrides
$body-bg: #000;
$body-color: #111;

// Bootstrap and its default variables
@import "../node_modules/bootstrap/scss/bootstrap";

stdbool.h defines macros true and false, but remember they are defined to be 1 and 0.

That is why sizeof(true) is 4.

You'll have to use [] notation to set keys dynamically.

var jsonVariable = {};
for(i=1; i<3; i++) {        
 var jsonKey  = i+'name';
 jsonVariable[jsonKey] = 'name1';

}

Now in ES6 you can use object literal syntax to create object keys dynamically, just wrap the variable in []

var key  = i + 'name';
data = {
    [key] : 'name1',
}

Just install pillow with pip install pillow and it will work.

Be sure the folder from where you send the file does not contain space !

I was trying to send a file to a remote server from my windows machine from VS code terminal, and I got this error even if the file was here.

It's because the folder where the file was contained space in its name...

For reading full response in Angular you should add the observe option:

{ observe: 'response' }

    return this.http.get(`${environment.serverUrl}/api/posts/${postId}/comments/?page=${page}&size=${size}`, { observe: 'response' });

Here is some example code to help you get started:

package com.acme;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class FileArrayProvider {

    public String[] readLines(String filename) throws IOException {
        FileReader fileReader = new FileReader(filename);
        BufferedReader bufferedReader = new BufferedReader(fileReader);
        List<String> lines = new ArrayList<String>();
        String line = null;
        while ((line = bufferedReader.readLine()) != null) {
            lines.add(line);
        }
        bufferedReader.close();
        return lines.toArray(new String[lines.size()]);
    }
}

And an example unit test:

package com.acme;

import java.io.IOException;

import org.junit.Test;

public class FileArrayProviderTest {

    @Test
    public void testFileArrayProvider() throws IOException {
        FileArrayProvider fap = new FileArrayProvider();
        String[] lines = fap
                .readLines("src/main/java/com/acme/FileArrayProvider.java");
        for (String line : lines) {
            System.out.println(line);
        }
    }
}

Hope this helps.

If you are using requests module, an alternative option is to write an auth class, as discussed in "New Forms of Authentication":

import requests

class BearerAuth(requests.auth.AuthBase):
    def __init__(self, token):
        self.token = token
    def __call__(self, r):
        r.headers["authorization"] = "Bearer " + self.token
        return r

and then can you send requests like this

response = requests.get('https://www.example.com/', auth=BearerAuth('3pVzwec1Gs1m'))

which allows you to use the same auth argument just like basic auth, and may help you in certain situations.

Create a new 640x480 image and fill it with purple (red+blue):

cv::Mat mat(480, 640, CV_8UC3, cv::Scalar(255,0,255));

Note:

• height before width
• type CV_8UC3 means 8-bit unsigned int, 3 channels
• colour format is BGR

The problem I was having with the rewrite is that some .htaccess files for Codeigniter, etc come with

RewriteBase /

Which doesn't seem to work in MAMP...at least for me.

Try this one (right):

<string name="content" formatted="false">Great application %s  ?  %s  ?  %s \\n\\nGo to download this application %s</string>

Here is a bit tricky, but portable solution:

• In your application implement a shutdown hook
• When you want to shut down your JVM gracefully, install a Java Agent that calls System.exit() using the Attach API.

I implemented the Java Agent. It is available on Github: https://github.com/everit-org/javaagent-shutdown

Detailed description about the solution is available here: https://everitorg.wordpress.com/2016/06/15/shutting-down-a-jvm-process/

Use imagesLoaded PACKAGED v3.1.8 (6.8 Kb when minimized). It is relatively old (since 2010) but still active project.

You can find it on github: https://github.com/desandro/imagesloaded

Their official site: http://imagesloaded.desandro.com/

Why it is better than using:

$(window).load() 

Because you may want to load images dynamically, like this: jsfiddle

$('#button').click(function(){
    $('#image').attr('src', '...');
});

The polynomial for CRC32 is:

x³² + x²⁶ + x²³ + x²² + x¹⁶ + x¹² + x¹¹ + x¹⁰ + x⁸ + x⁷ + x⁵ + x⁴ + x² + x + 1

• Wikipedia
• CRC calculation

Or in hex and binary:

0x 01 04 C1 1D B7
1 0000 0100 1100 0001 0001 1101 1011 0111

The highest term (x³²) is usually not explicitly written, so it can instead be represented in hex just as

0x 04 C1 1D B7

Feel free to count the 1s and 0s, but you'll find they match up with the polynomial, where 1 is bit 0 (or the first bit) and x is bit 1 (or the second bit).

Why this polynomial? Because there needs to be a standard given polynomial and the standard was set by IEEE 802.3. Also it is extremely difficult to find a polynomial that detects different bit errors effectively.

You can think of the CRC-32 as a series of "Binary Arithmetic with No Carries", or basically "XOR and shift operations". This is technically called Polynomial Arithmetic.

• CRC primer, Chapter 5

To better understand it, think of this multiplication:

(x^3 + x^2 + x^0)(x^3 + x^1 + x^0)
= (x^6 + x^4 + x^3
 + x^5 + x^3 + x^2
 + x^3 + x^1 + x^0)
= x^6 + x^5 + x^4 + 3*x^3 + x^2 + x^1 + x^0

If we assume x is base 2 then we get:

x^7 + x^3 + x^2 + x^1 + x^0

• CRC primer Chp.5

Why? Because 3x^3 is 11x^11 (but we need only 1 or 0 pre digit) so we carry over:

=1x^110 + 1x^101 + 1x^100          + 11x^11 + 1x^10 + 1x^1 + x^0
=1x^110 + 1x^101 + 1x^100 + 1x^100 + 1x^11 + 1x^10 + 1x^1 + x^0
=1x^110 + 1x^101 + 1x^101          + 1x^11 + 1x^10 + 1x^1 + x^0
=1x^110 + 1x^110                   + 1x^11 + 1x^10 + 1x^1 + x^0
=1x^111                            + 1x^11 + 1x^10 + 1x^1 + x^0

But mathematicians changed the rules so that it is mod 2. So basically any binary polynomial mod 2 is just addition without carry or XORs. So our original equation looks like:

=( 1x^110 + 1x^101 + 1x^100 + 11x^11 + 1x^10 + 1x^1 + x^0 ) MOD 2
=( 1x^110 + 1x^101 + 1x^100 +  1x^11 + 1x^10 + 1x^1 + x^0 )
= x^6 + x^5 + x^4 + 3*x^3 + x^2 + x^1 + x^0 (or that original number we had)

I know this is a leap of faith but this is beyond my capability as a line-programmer. If you are a hard-core CS-student or engineer I challenge to break this down. Everyone will benefit from this analysis.

So to work out a full example:

   Original message                : 1101011011
   Polynomial of (W)idth 4         :      10011
   Message after appending W zeros : 11010110110000

Now we divide the augmented Message by the Poly using CRC arithmetic. This is the same division as before:

            1100001010 = Quotient (nobody cares about the quotient)
       _______________
10011 ) 11010110110000 = Augmented message (1101011011 + 0000)
=Poly   10011,,.,,....

         10011,.,,....

               00000..

                10100.
                10011.
                -----.
                 01110
                 00000
                 -----
                  1110 = Remainder = THE CHECKSUM!!!!

The division yields a quotient, which we throw away, and a remainder, which is the calculated checksum. This ends the calculation. Usually, the checksum is then appended to the message and the result transmitted. In this case the transmission would be: 11010110111110.

• CRC primer, Chapter 7

Only use a 32-bit number as your divisor and use your entire stream as your dividend. Throw out the quotient and keep the remainder. Tack the remainder on the end of your message and you have a CRC32.

Average guy review:

         QUOTIENT
        ----------
DIVISOR ) DIVIDEND
                 = REMAINDER

1. Take the first 32 bits.
2. Shift bits
3. If 32 bits are less than DIVISOR, go to step 2.
4. XOR 32 bits by DIVISOR. Go to step 2.

(Note that the stream has to be dividable by 32 bits or it should be padded. For example, an 8-bit ANSI stream would have to be padded. Also at the end of the stream, the division is halted.)

If you don't want to save any changes and don't want that Save prompt while saving an Excel file using Macro then this piece of code may helpful for you

Sub Auto_Close()

     ThisWorkbook.Saved = True

End Sub

Because the Saved property is set to True, Excel responds as though the workbook has already been saved and no changes have occurred since that last save, so no Save prompt.

The most simple and straightforward C/C++ implementation that I found is in a link at the bottom of this page:

Web Page: http://www.barrgroup.com/Embedded-Systems/How-To/CRC-Calculation-C-Code

Code Download Link: https://barrgroup.com/code/crc.zip

It is a simple standalone implementation with one .h and one .c file. There is support for CRC32, CRC16 and CRC_CCITT thru the use of a define. Also, the code lets the user change parameter settings like the CRC polynomial, initial/final XOR value, and reflection options if you so desire.

The license is not explicitly defined ala LGPL or similar. However the site does say that they are placing the code in the public domain for any use. The actual code files also say this.

Hope it helps!

Key points which explain difference and provide guidance upon working with unittest.mock

1. Use Mock if you want to replace some interface elements(passing args) of the object under test
2. Use patch if you want to replace internal call to some objects and imported modules of the object under test
3. Always provide spec from the object you are mocking
   • With patch you can always provide autospec
   • With Mock you can provide spec
   • Instead of Mock, you can use create_autospec, which intended to create Mock objects with specification.

In the question above the right answer would be to use Mock, or to be more precise create_autospec (because it will add spec to the mock methods of the class you are mocking), the defined spec on the mock will be helpful in case of an attempt to call method of the class which doesn't exists ( regardless signature), please see some

        with patch(f'{__name__}.MyClass', autospec=True) as mock:
            # Fails because of signature misuse.
            result = second(mock)
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)
    
    def test_second(self):
        mock = Mock()
        mock.unexisted_method.return_value = True
        
        result = second(mock)
        
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)

The test cases with defined spec used fail because methods called from something and second functions aren't complaint with MyClass, which means - they catch bugs, whereas default Mock will display.

As a side note there is one more option: use patch.object to mock just the class method which is called with.

The good use cases for patch would be the case when the class is used as inner part of function:

def something():
    arg = 1
    return MyClass.method(arg)

Then you will want to use patch as a decorator to mock the MyClass.

ALTER TABLE Merchant_Pending_Functions MODIFY COLUMN `NumberOfLocations` INT null;

This will work for you.

If you want to change a not null column to allow null, no need to include not null clause. Because default columns get not null.

ALTER TABLE Merchant_Pending_Functions MODIFY COLUMN `NumberOfLocations` INT;

You can also take advantage of the built-in Service Parameters system, which lets you isolate or reuse the value:

# app/config/parameters.yml
parameters:
    ga_tracking: UA-xxxxx-x

# app/config/config.yml
twig:
    globals:
        ga_tracking: "%ga_tracking%"

Now, the variable ga_tracking is available in all Twig templates:

<p>The google tracking code is: {{ ga_tracking }}</p>

The parameter is also available inside the controllers:

$this->container->getParameter('ga_tracking');

You can also define a service as a global Twig variable (Symfony2.2+):

# app/config/config.yml
twig:
    # ...
    globals:
        user_management: "@acme_user.user_management"

http://symfony.com/doc/current/templating/global_variables.html

If the global variable you want to set is more complicated - say an object - then you won't be able to use the above method. Instead, you'll need to create a Twig Extension and return the global variable as one of the entries in the getGlobals method.
