The terms "stress testing" and "load testing" are often used interchangeably by software test engineers but they are really quite different.
Stress testing
In Stress testing we tries to break the system under test by overwhelming its resources or by taking resources away from it (in which case it is sometimes called negative testing). The main purpose behind this madness is to make sure that the system fails and recovers gracefully -- this quality is known as recoverability. OR Stress testing is the process of subjecting your program/system under test (SUT) to reduced resources and then examining the SUT’s behavior by running standard functional tests. The idea of this is to expose problems that do not appear under normal conditions.For example, a multi-threaded program may work fine under normal conditions but under conditions of reduced CPU availability, timing issues will be different and the SUT will crash. The most common types of system resources reduced in stress testing are CPU, internal memory, and external disk space. When performing stress testing, it is common to call the tools which reduce these three resources EatCPU, EatMem, and EatDisk respectively.
While on the other hand Load Testing
In case of Load testing Load testing is the process of subjecting your SUT to heavy loads, typically by simulating multiple users( Using Load runner), where "users" can mean human users or virtual/programmatic users. The most common example of load testing involves subjecting a Web-based or network-based application to simultaneous hits by thousands of users. This is generally accomplished by a program which simulates the users. There are two main purposes of load testing: to determine performance characteristics of the SUT, and to determine if the SUT "breaks" gracefully or not.
In the case of a Web site, you would use load testing to determine how many users your system can handle and still have adequate performance, and to determine what happens with an extreme load — will the Web site generate a "too busy" message for users, or will the Web server crash in flames?
We tried a few applications, both trials of commercial products and freely available ones. Ultimately, it was the trial edition of the Team Test Load Agent software that we tried. It definitely works great and is fairly simple to use. In the long run, it bolstered our argument to move to Team Foundation Server and equip all parts of the department with the appropriate tooling.
The obvious downside, however, is the price.
There are a lot of good tools mentioned here. I wonder if tools are an answer the question: "How do you stress test a web application?" The tools don't really provide a method to stress a Web app. Here's what I know:
Stress testing shows how a Web app fails while serving responses to an increasing population of users. Stress testing shows how the Web app functions while it fails. Most Web apps today - especially the Social/Mobile Web apps - are integrations of services. For example, when Facebook had its outage in May 2011 you could not log onto Pepsi.com's Web app. The app didn't fail entirely, just a big portion of its normal function become unavailable to users.
Performance testing shows a Web app's ability to maintain response times independent of how many users are concurrently using the app. For example, an app that handles 10 transactions per second with 10 concurrent users should handle 20 transactions per second at 20 users. If the app handles less than 20 transactions per second the response times are growing longer and the app is not able to achieve linear scalability.
Also, in the above example the transaction-per-second count should be of only successful operations of a test use case/workflow. Failures typically happen in shorter timespans and will make the TPS measurement overly optimistic. Failures are important to a stress and performance test since they generate load on the app too.
I wrote up the PushToTest methodology in the TestMaker User Guide at http://www.pushtotest.com/pushtotest-testmaker-6-methodology. TestMaker comes in two flavors: Open Source (GPL) Community version and TestMaker Enterprise (commercial with great professional support.)

git pull origin master
this will sync your master to the central repo and if new branches are pushed to the central repo it will also update your clone copy.
Use Lookupstage to decide whether to insert or update. Check this link for more info - http://beingoyen.blogspot.com/2010/03/ssis-how-to-update-instead-of-insert.html
Steps to do update:
Under Custom properties select SQLCOMMAND and insert update command ex:
UPDATE table1 SET col1 = ?, col2 = ? where id = ?
map columns in exact order from source to output as in update command
All the answers were great however what did it for me was a combination of uninstalling Pillow
pip uninstall Pillow
Then installing whatever packages you need e.g.
sudo apt-get -y install python-imaging
sudo apt-get -y install zlib1g-dev
sudo apt-get -y install libjpeg-dev
And then using easy_install to reinstall Pillow
easy_install Pillow
Hope this helps others
I know it's an old question now but i thought it might help others. I wanted something a little easier to implement for a few apps i had, so i made a class for this. You can download it here if you want: https://github.com/sdernley/iOSTextFieldHandler
It's as simple as setting all of the UITextFields to have a delegate of self
textfieldname.delegate = self;
And then adding this to your view controller with the name of your scrollView and submit button
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
[iOSTextFieldHandler TextboxKeyboardMover:containingScrollView tf:textField btn:btnSubmit];
}
You might get better results if you try:
console.log(JSON.stringify(functor));
Please use this command and try :
redis-cli --raw keys "$PATTERN" | xargs redis-cli del
What I usually do for putting alert box (e.g. Note or Warning) in markdown texts (not only when using pandoc but also every where that markdown is supported) is surrounding the content with two horizontal lines:
---
**NOTE**
It works with almost all markdown flavours (the below blank line matters).
---
which would be something like this:
NOTE
It works with all markdown flavours (the below blank line matters).
The good thing is that you don't need to worry about which markdown flavour is supported or which extension is installed or enabled.
EDIT: As @filups21 has mentioned in the comments, it seems that a horizontal line is represented by ***
in RMarkdown. So, the solution mentioned before does not work with all markdown flavours as it was originally claimed.
I tried with "mMap.animateCamera( CameraUpdateFactory.zoomTo( 17.0f ) );" but it didn't work for me. So I used this animation for zooming in on start.
LatLng loc = new LatLng(33.8688, 151.2093);
mMap.addMarker(new MarkerOptions().position(loc).title("Sydney"));
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 18), 5000, null);
By default, MomentJS parses in local time. If only a date string (with no time) is provided, the time defaults to midnight.
In your code, you create a local date and then convert it to the UTC timezone (in fact, it makes the moment instance switch to UTC mode), so when it is formatted, it is shifted (depending on your local time) forward or backwards.
If the local timezone is UTC+N (N being a positive number), and you parse a date-only string, you will get the previous date.
Here are some examples to illustrate it (my local time offset is UTC+3 during DST):
>>> moment('07-18-2013', 'MM-DD-YYYY').utc().format("YYYY-MM-DD HH:mm")
"2013-07-17 21:00"
>>> moment('07-18-2013 12:00', 'MM-DD-YYYY HH:mm').utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 09:00"
>>> Date()
"Thu Jul 25 2013 14:28:45 GMT+0300 (Jerusalem Daylight Time)"
If you want the date-time string interpreted as UTC, you should be explicit about it:
>>> moment(new Date('07-18-2013 UTC')).utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"
or, as Matt Johnson mentions in his answer, you can (and probably should) parse it as a UTC date in the first place using moment.utc()
and include the format string as a second argument to prevent ambiguity.
>>> moment.utc('07-18-2013', 'MM-DD-YYYY').format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"
To go the other way around and convert a UTC date to a local date, you can use the local()
method, as follows:
>>> moment.utc('07-18-2013', 'MM-DD-YYYY').local().format("YYYY-MM-DD HH:mm")
"2013-07-18 03:00"
I noticed that leowebdev's post did seem to work on my end, however, it did knock out two elements of the site that I am trying to make: the scrolling and the footer.
The scrolling I got back by adding a
scrolling="yes"
To the iframe embed code.
I am not sure if the footer is automatically knocked out because of the responsiveness or not, but hopefully someone else knows that answer.
Any algorithm/library that supports a preset dictionary, e.g. zlib.
This way you can prime the compressor with the same kind of text that is likely to appear in the input. If the files are similar in some way (e.g. all URLs, all C programs, all StackOverflow posts, all ASCII-art drawings) then certain substrings will appear in most or all of the input files.
Every compression algorithm will save space if the same substring is repeated multiple times in one input file (e.g. "the" in English text or "int" in C code.)
But in the case of URLs certain strings (e.g. "http://www.", ".com", ".html", ".aspx" will typically appear once in each input file. So you need to share them between files somehow rather than having one compressed occurrence per file. Placing them in a preset dictionary will achieve this.
My personal opinion is that you should avoid using JSP/ASP/PHP/etc pages. Instead output to an API similar to SAX (only designed for calling rather than handling). That way there is a single layer that has to create well formed output.
Bigger C++ projects I've seen hardly used more than one namespace (e.g. boost library).
Actually boost uses tons of namespaces, typically every part of boost has its own namespace for the inner workings and then may put only the public interface in the top-level namespace boost.
Personally I think that the larger a code-base becomes, the more important namespaces become, even within a single application (or library). At work we put each module of our application in its own namespace.
Another use (no pun intended) of namespaces that I use a lot is the anonymous namespace:
namespace {
const int CONSTANT = 42;
}
This is basically the same as:
static const int CONSTANT = 42;
Using an anonymous namespace (instead of static) is however the recommended way for code and data to be visible only within the current compilation unit in C++.
Adding my two cents, based on a performance issue I observed.
If simple queries are getting parellelized unnecessarily, it can bring more problems than solving one. However, before adding MAXDOP into the query as "knee-jerk" fix, there are some server settings to check.
In Jeremiah Peschka - Five SQL Server Settings to Change, MAXDOP and "COST THRESHOLD FOR PARALLELISM" (CTFP
) are mentioned as important settings to check.
Note: Paul White mentioned max server memory
aslo as a setting to check, in a response to Performance problem after migration from SQL Server 2005 to 2012. A good kb article to read is Using large amounts of memory can result in an inefficient plan in SQL Server
Jonathan Kehayias - Tuning ‘cost threshold for parallelism’ from the Plan Cache helps to find out good value for CTFP
.
Why is cost threshold for parallelism ignored?
Aaron Bertrand - Six reasons you should be nervous about parallelism has a discussion about some scenario where MAXDOP is the solution.
Parallelism-Inhibiting Components are mentioned in Paul White - Forcing a Parallel Query Execution Plan
You most likely just need to format your integer:
'%0*d' % (fill, your_int)
For example,
>>> '%0*d' % (3, 4)
'004'
If you want to print multiple rows, you can iterate through the result by using a cursor. e.g. print all names from sys.database_principals
DECLARE @name nvarchar(128)
DECLARE cur CURSOR FOR
SELECT name FROM sys.database_principals
OPEN cur
FETCH NEXT FROM cur INTO @name;
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT @name
FETCH NEXT FROM cur INTO @name;
END
CLOSE cur;
DEALLOCATE cur;
If you add in app.gradle under android{
lintOptions {
quiet true
abortOnError false
}
}
It will get work
Edit -> Project Settings -> Editor
Set Version Control to meta files. Set Asset Serialization to force text.
I think this is what you want.
You want to read raw lines to avoid problems with backslashes in the input (use -r
):
while read -r line; do
printf "<%s>\n" "$line"
done < file.txt
This will keep whitespace within the line, but removes leading and trailing whitespace. To keep those as well, set the IFS empty, as in
while IFS= read -r line; do
printf "%s\n" "$line"
done < file.txt
This now is an equivalent of cat < file.txt
as long as file.txt
ends with a newline.
Note that you must double quote "$line"
in order to keep word splitting from splitting the line into separate words--thus losing multiple whitespace sequences.
listView1.View = View.Details;
listView1.Columns.Add("Target No.", 83, HorizontalAlignment.Center);
listView1.Columns.Add(" Range ", 100, HorizontalAlignment.Center);
listView1.Columns.Add(" Azimuth ", 100, HorizontalAlignment.Center);
i also had same problem .. i drag column to left .. but now ok .. so let's say i have 283*196 size of listview ..... We declared in the column width -2 for auto width .. For fitting in the listview ,we can divide listview width into 3 parts (83,100,100) ...
If you want them to be really equal (i.e. the same items and the same number of each item), I think that the simplest solution is to sort before comparing:
Enumerable.SequenceEqual(list1.OrderBy(t => t), list2.OrderBy(t => t))
Here is a solution that performs a bit better (about ten times faster), and only requires IEquatable
, not IComparable
:
public static bool ScrambledEquals<T>(IEnumerable<T> list1, IEnumerable<T> list2) {
var cnt = new Dictionary<T, int>();
foreach (T s in list1) {
if (cnt.ContainsKey(s)) {
cnt[s]++;
} else {
cnt.Add(s, 1);
}
}
foreach (T s in list2) {
if (cnt.ContainsKey(s)) {
cnt[s]--;
} else {
return false;
}
}
return cnt.Values.All(c => c == 0);
}
To handle any data type as key (for example nullable types as Frank Tzanabetis pointed out), you can make a version that takes a comparer for the dictionary:
public static bool ScrambledEquals<T>(IEnumerable<T> list1, IEnumerable<T> list2, IEqualityComparer<T> comparer) {
var cnt = new Dictionary<T, int>(comparer);
...
In C++11 you can. A note beforehand: Don't new
the array, there's no need for that.
First, string[] strArray
is a syntax error, that should either be string* strArray
or string strArray[]
. And I assume that it's just for the sake of the example that you don't pass any size parameter.
#include <string>
void foo(std::string* strArray, unsigned size){
// do stuff...
}
template<class T>
using alias = T;
int main(){
foo(alias<std::string[]>{"hi", "there"}, 2);
}
Note that it would be better if you didn't need to pass the array size as an extra parameter, and thankfully there is a way: Templates!
template<unsigned N>
void foo(int const (&arr)[N]){
// ...
}
Note that this will only match stack arrays, like int x[5] = ...
. Or temporary ones, created by the use of alias
above.
int main(){
foo(alias<int[]>{1, 2, 3});
}
You cannot concatenate multiple fields with a string. You need to select a field instand of all (*
).
The code is okay but you are in the wrong directory. You must run these commands inside your rails project-directory.
The normal way to get there from scratch is:
$ rails new PROJECT_NAME
$ cd PROJECT_NAME
$ rails generate model ad \
name:string \
description:text \
price:decimal \
seller_id:integer \
email:string img_url:string
If you are debugging or similar - In chrome developer tools, you can simply use
$x('/html/.//div[@id="text"]')
Using Xamarin, this works for me inside a Fragment:
using Android.Views.InputMethods;
using Android.Content;
...
if ( _txtSearch.RequestFocus() ) {
var inputManager = (InputMethodManager) Activity.GetSystemService( Context.InputMethodService );
inputManager.ShowSoftInput( _txtSearch, ShowFlags.Implicit );
}
You could is isArray method but I would prefer to check with
Object.getPrototypeOf(yourvariable) === Array.prototype

Dim WS as Worksheet
Set WS = Sheets.Add
You don't have to know where it's located, or what it's name is, you just refer to it as WS.
If you still want to do this the "old fashioned" way, try this:
Sheets.Add.Name = "Test"
I tested dkarp's solution with gmail and it was filtered to spam. Use the Reply-To header instead (or in addition, although gmail apparently doesn't need it). Here's how linkedin does it:
Sender: [email protected]
From: John Doe via LinkedIn <[email protected]>
Reply-To: John Doe <[email protected]>
To: My Name <[email protected]>
Once I switched to this format, gmail is no longer filtering my messages as spam.
homes.sort(function(a,b) { return a.city - b.city } );
homes.sort(function(a,b){
if (a.city==b.city){
return parseFloat(b.price) - parseFloat(a.price);
} else {
return 0;
}
});
As of the time of this writing, Swift natively supports comparing Dates with all comparison operators (i.e. <
, <=
, ==
, >=
, and >
). You can also compare optional Dates but are limited to <
, ==
, and >
. If you need to compare two optional dates using <=
or >=
, i.e.
let date1: Date? = ...
let date2: Date? = ...
if date1 >= date2 { ... }
You can overload the <=
and >=
operators to support optionals:
func <= <T: Comparable>(lhs: T?, rhs: T?) -> Bool {
return lhs == rhs || lhs < rhs
}
func >= <T: Comparable>(lhs: T?, rhs: T?) -> Bool {
return lhs == rhs || lhs > rhs
}
%0|%0
is a fork bomb. It will spawn another process using a pipe |
which runs a copy of the same program asynchronously. This hogs the CPU and memory, slowing down the system to a near-halt (or even crash the system).
%0
refers to the command used to run the current program. For example, script.bat
A pipe |
symbol will make the output or result of the first command sequence as the input for the second command sequence. In the case of a fork bomb, there is no output, so it will simply run the second command sequence without any input.
Expanding the example, %0|%0
could mean script.bat|script.bat
. This runs itself again, but also creating another process to run the same program again (with no input).
from flask import request
request.headers.get('your-header-name')
request.headers
behaves like a dictionary, so you can also get your header like you would with any dictionary:
request.headers['your-header-name']
Floating point numbers only have so many significant digits, but they can go much higher. If your app will ever handle large numbers, you will notice the epsilon value should be different.
0.001+0.001 = 0.002 BUT 12,345,678,900,000,000,000,000+1=12,345,678,900,000,000,000,000 if you are using floating point and double. It's not a good representation of money, unless you are damn sure you'll never handle more than a million dollars in this system.
Simple way without methods
int x = 1, y = 2, z = 3;
int biggest = x;
if (y > biggest) {
biggest = y;
}
if (z > biggest) {
biggest = z;
}
System.out.println(biggest);
// System.out.println(Math.max(Math.max(x,y),z));
You can bulk import all aliases from one keystore to another:
keytool -importkeystore -srckeystore source.jks -destkeystore dest.jks
I found a solution for my problem while writing my question !
Going into my remote session i tried two key combinations, and it solved the problem on my Desktop : Alt+Enter and Ctrl+Enter (i don't know which one solved the problem though)
I tried to reproduce the problem, but i couldn't... but i'm almost sure it's one of the key combinations described in the question above (since i experienced this problem several times)
So it seems the problem comes from the use of RDP (windows7 and 8)
Update 2017: Problem occurs on Windows 10 aswell.
Even though a bit old thread, for those who still looking for the differences:
Aside from layout (space) taken in Hidden and not taken in Collapsed, there is another difference.
If we have custom controls inside this 'Collapsed' main control, the next time we set it to Visible, it will "load" all custom controls. It will not pre-load when window is started.
As for 'Hidden', it will load all custom controls + main control which we set as hidden when the "window" is started.
Is the tblPersoon
implementing IEnumerable<T>
? You may need to do it using:
var query = (from p in tblPersoon.Cast<Person>() select p).Single();
This kind of error (Could not find an implementation of the query pattern) usually occurs when:
using System.Linq
)IEnumerable<T>
Edit:
Apart from fact you query type (tblPersoon
) instead of property tblPersoons
, you also need an context instance (class that defines tblPersoons
property), like this:
public tblPersoon GetPersoonByID(string id)
{
var context = new DataClasses1DataContext();
var query = context.tblPersoons.Where(p => p.id == id).Single();

In rails 4 you can now use a css and sass helper image-url:
div.logo {background-image: image-url("logo.png");}
If your background images aren't showing up consider looking at how you're referencing them in your stylesheets.
compileSdkVersion : The compileSdkVersion is the version of the API the app is compiled against. This means you can use Android API features included in that version of the API (as well as all previous versions, obviously). If you try and use API 16 features but set compileSdkVersion to 15, you will get a compilation error. If you set compileSdkVersion to 16 you can still run the app on a API 15 device.
minSdkVersion : The min sdk version is the minimum version of the Android operating system required to run your application.
targetSdkVersion : The target sdk version is the version your app is targeted to run on.
if you are on Windows
sqlplus / as sysdba
Now you are logged with SYS user and you can do anything you want (query DBA_USERS to find out your username, or change any user password). You can not see the old password, you can only change it.
If you VS solution contains several projects, select all of them in the right pane, and press "properties". Then go to C++ -> Code Generation and chose one Run Time library option for all of them
Once I'd discovered all the information of how my client was handling the encryption/decryption at their end it was straight forward using the AesManaged example suggested by dtb.
The finally implemented code started like this:
try
{
// Create a new instance of the AesManaged class. This generates a new key and initialization vector (IV).
AesManaged myAes = new AesManaged();
// Override the cipher mode, key and IV
myAes.Mode = CipherMode.ECB;
myAes.IV = new byte[16] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; // CRB mode uses an empty IV
myAes.Key = CipherKey; // Byte array representing the key
myAes.Padding = PaddingMode.None;
// Create a encryption object to perform the stream transform.
ICryptoTransform encryptor = myAes.CreateEncryptor();
// TODO: perform the encryption / decryption as required...
}
catch (Exception ex)
{
// TODO: Log the error
throw ex;
}
Try this:
$mpdf->Output('my_filename.pdf','D');
because:
D
- means Download
F
- means File-save only
There should be templates already included in Visio 2007 for software architecture but you might want to check out Visio 2007 templates.
To use CSS3 Animation you must also define the actual animation keyframes (which you named spin
)
Read https://developer.mozilla.org/en-US/docs/CSS/Tutorials/Using_CSS_animations for more info
Once you've configured the animation's timing, you need to define the appearance of the animation. This is done by establishing two or more keyframes using the
@keyframes
at-rule. Each keyframe describes how the animated element should render at a given time during the animation sequence.
Demo at http://jsfiddle.net/gaby/9Ryvs/7/
@-moz-keyframes spin {
from { -moz-transform: rotate(0deg); }
to { -moz-transform: rotate(360deg); }
}
@-webkit-keyframes spin {
from { -webkit-transform: rotate(0deg); }
to { -webkit-transform: rotate(360deg); }
}
@keyframes spin {
from {transform:rotate(0deg);}
to {transform:rotate(360deg);}

Twitter Bootstrap v3.0.3 has a class: center-block
Center content blocks
Set an element to display: block and center via margin. Available as a mixin and class.
Just need to add a class .center-block
in the img
tag, looks like this
<div class="container">
<div class="row">
<div class="span4"></div>
<div class="span4"><img class="center-block" src="logo.png" /></div>
<div class="span4"></div>
</div>
</div>
In Bootstrap already has css style call .center-block
.center-block {
display: block;
margin-left: auto;
margin-right: auto;
}

You can pass the value to the function using this.value
, where this
points to the button
<input type="button" value="mybutton1" onclick="dosomething(this.value)">
And then access that value in the function
function dosomething(val){
console.log(val);
}
If ng-init
is not for passing objects into $scope
, you can always write your own directive. So here is what I got:
http://jsfiddle.net/goliney/89bLj/
Javasript:
var app = angular.module('myApp', []);
app.directive('initData', function($parse) {
return function(scope, element, attrs) {
//modify scope
var model = $parse(attrs.initData);
model(scope);
};
});
function Ctrl1($scope) {
//should be defined
$scope.inputdata = {foo:"east", bar:"west"};
}
Html:
<div ng-controller="Ctrl1">
<div init-data="inputdata.foo=123; inputdata.bar=321"></div>
</div>
But my approach can only modify objects, which are already defined at controller.
If you just want to update a few packages and not all, you can list them as such:
php composer.phar update vendor/package:2.* vendor/package2:dev-master
You can also use wildcards to update a bunch of packages at once:
php composer.phar update vendor/*
source
when available.dist
when available.php

, lib-*
and ext-*
requirements and force the installation even if the local machine does not fulfill these. See also the platform

.For Asp.Net MVC
@Html.ListBox("parameterName", ViewBag.ParameterValueList as MultiSelectList,
new {
@class = "chosen-select form-control"
})
or
@Html.ListBoxFor(model => model.parameterName,
ViewBag.ParameterValueList as MultiSelectList,
new{
data_placeholder = "Select Options ",
@class = "chosen-select form-control"
})
If you are using a version of jQuery that is less than version 1.8 you can use the $('.class').size() which takes zero parameters. See documentation for more information on .size() method.
However if you are using (or plan to upgrade) to 1.8 or greater you can use $('.class').length property. See documentation for more information on .length property.
This is an old question but I recently stumbled upon it.

My background image wasn't working because the URL had a space in it and thus I needed to URL encode it.
You can check if this is the issue you're having by trying a different image URL that doesn't have characters that need escaping.
You could do this to the data in the component just using Javascripts built in encodeURI() method.
Personally I wanted to create a pipe for it so that it could be used in the template.
To do this you can create a very simple pipe. For example:
src/app/pipes/encode-uri.pipe.ts
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name: 'encodeUri'
})
export class EncodeUriPipe implements PipeTransform {
transform(value: any, args?: any): any {
return encodeURI(value);
}
}
src/app/app.module.ts
import { EncodeUriPipe } from './pipes/encode-uri.pipe';
...
@NgModule({
imports: [
BrowserModule,
AppRoutingModule
...
],
exports: [
...
],
declarations: [
AppComponent,
EncodeUriPipe
],
bootstrap: [ AppComponent ]
})
export class AppModule { }
src/app/app.component.ts
import {Component} from '@angular/core';
@Component({
// tslint:disable-next-line
selector: 'body',
template: '<router-outlet></router-outlet>'
})
export class AppComponent {
myUrlVariable: string;
constructor() {
this.myUrlVariable = 'http://myimagewith space init.com';
}
}
src/app/app.component.html
<div [style.background-image]="'url(' + (myUrlVariable | encodeUri) + ')'" ></div>
When you call notify() from an object t, java notifies a particular t.wait() method. But, how does java search and notify a particular wait method.
java only looks into the synchronized block of code which was locked by object t. java cannot search the whole code to notify a particular t.wait().
Try this:
<form class="form-horizontal" role="form" method="post" name="registration" novalidate>
<div class="form-group" ng-class="{'has-error': registration.phone.$error.number}">
<label for="inputPhone" class="col-sm-3 control-label">Phone :</label>
<div class="col-sm-9">
<input type="number"
class="form-control"
ng-minlength="10"
ng-maxlength="10"
id="inputPhone"
name="phone"
placeholder="Phone"
ng-model="user.phone"
ng-required="true">
<span class="help-block"
ng-show="registration.phone.$error.required ||
registration.phone.$error.number">
Valid phone number is required
</span>
<span class="help-block"
ng-show="((registration.phone.$error.minlength ||
registration.phone.$error.maxlength) &&
registration.phone.$dirty) ">
phone number should be 10 digits
</span>
You can do git merge --abort
after seeing that there are conflicts.
One possible solution can be
class Survey{
void renderSurvey(Question q) {
/*
Depending on the type of question (choice, dropdwn or other, I have to render
the question on the UI. The class that calls this doesnt have compile time
knowledge of the type of question that is going to be rendered. Each question
type has its own rendering function. If this is for choice , I need to access
its functions using q.
*/
if(q.getOption() instanceof ChoiceQuestionOption)
{
ChoiceQuestionOption choiceQuestion = (ChoiceQuestionOption)q.getOption();
boolean result = choiceQuestion.getMultiple();
//do something with result......
}
}
}
You can use bringToFront
:
View view=findViewById(R.id.btnStartGame);
view.bringToFront();
I do not pretend to show something new, just want to summarize solutions above for those who likes to use Promise functions in their code (like me).
const archiver = require('archiver');
/**
* @param {String} source
* @param {String} out
* @returns {Promise}
*/
function zipDirectory(source, out) {
const archive = archiver('zip', { zlib: { level: 9 }});
const stream = fs.createWriteStream(out);
return new Promise((resolve, reject) => {
archive
.directory(source, false)
.on('error', err => reject(err))
.pipe(stream)
;
stream.on('close', () => resolve());
archive.finalize();
});
}
Hope it will help someone ;)
>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True
So it doesn't matter, they are all the same value.
The only reason all three modules provide a pi
value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.
If you want to have a simple Line in your Layout to separate two views you can use a generic View with the height and width you want the line to have and a set background color.
With this approach you don't need to override a View or use a Canvas yourself just simple and clean add the line in xml.
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="@android:color/black" />
The example code I provided will generate a line that fills the screen in width and has a height of one dp.
If you have problems with the drawing of the line on small screens consider to change the height of the line to px. The problem is that on a ldpi screen the line will be 0.75 pixel high. Sometimes this may result in a rounding that makes the line vanish. If this is a problem for your layout define the width of the line a ressource file and create a separate ressource file for small screens that sets the value to 1px instead of 1dp.
This approach is only usable if you want horizontal or vertical lines that are used to divide layout elements. If you want to achieve something like a cross that is drawn into an image my approach will not work.
If you are entering your credentials into the Visual Studio popup you might see an error that says "Login was not successful". However, this might not be true. Studio will open a browser window saying that it was in fact successful. There is then a dance between the browser and Studio where you need to accept / allow the authentication at certain points.
Another way to do : json_encode( booleanValue )
echo json_encode(true); // string "true"
echo json_encode(false); // string "false"
// null !== false
echo json_encode(null); // string "null"
Empty is a subset of any string.
Think of them as what is between every two characters.
Kind of the way there are an infinite number of points on any sized line...
(Hmm... I wonder what I would get if I used calculus to concatenate an infinite number of empty strings)
Note that "".equals("") only though.
I don't really see a way to do this as-is. I think you might need to remove the overflow:hidden
from div#1 and add another div within div#1 (ie as a sibling to div#2) to hold your unspecified 'content' and add the overflow:hidden
to that instead. I don't think that overflow can be (or should be able to be) over-ridden.
Some of the answers of this post are valid, but using TypeToken, the Gson library generates a Tree objects whit unreal types for your application.
To get it I had to read the array and convert one by one the objects inside the array. Of course this method is not the fastest and I don't recommend to use it if you have the array is too big, but it worked for me.
It is necessary to include the Json library in the project. If you are developing on Android, it is included:
/**
* Convert JSON string to a list of objects
* @param sJson String sJson to be converted
* @param tClass Class
* @return List<T> list of objects generated or null if there was an error
*/
public static <T> List<T> convertFromJsonArray(String sJson, Class<T> tClass){
try{
Gson gson = new Gson();
List<T> listObjects = new ArrayList<>();
//read each object of array with Json library
JSONArray jsonArray = new JSONArray(sJson);
for(int i=0; i<jsonArray.length(); i++){
//get the object
JSONObject jsonObject = jsonArray.getJSONObject(i);
//get string of object from Json library to convert it to real object with Gson library
listObjects.add(gson.fromJson(jsonObject.toString(), tClass));
}
//return list with all generated objects
return listObjects;
}catch(Exception e){
e.printStackTrace();
}
//error: return null
return null;
}
You need to add quotes. VBA is translating
Rows(copyToRow & ":" & copyToRow).Select`
into
Rows(52:52).Select
Try changing
Rows(""" & copyToRow & ":" & copyToRow & """).Select
create table question_bank
(
question_id uniqueidentifier primary key,
question_exam_id uniqueidentifier not null,
question_text varchar(1024) not null,
question_point_value decimal,
constraint fk_questionbank_exams foreign key (question_exam_id) references exams (exam_id)
);
From oracle documentation page:
If your method overrides one of its superclass's methods, you can invoke the overridden method through the use of the keyword
super
.
You can also use super
to refer to a hidden field (although hiding fields is discouraged).
Use of super
in constructor of subclasses:
Invocation of a superclass constructor must be the first line in the subclass constructor.
The syntax for calling a superclass constructor is
super();
or:
super(parameter list);
With super()
, the superclass no-argument constructor is called. With super(parameter list)
, the superclass constructor with a matching parameter list is called.
Note: If a constructor does not explicitly invoke a superclass constructor, the Java compiler automatically inserts a call to the no-argument constructor of the superclass. If the super class does not have a no-argument constructor, you will get a compile-time error.

When I went to Google fonts all they gave me were true type font files .ttf
and didn't explain at all how to use the @font-face to include them into my document. I tried the web font generator from font squirrel too, which just kept running the loading gif and not working... I then found this site -
I had great success using the following method:
I selected the Add Fonts button, leaving the default options, added all of my .ttf
that Google gave me for Open Sans
(which was like 10, I chose a lot of options...).
Then I selected the Convert button.
Heres the best part!
They gave me a zip file with all the font format files I selected, .ttf
, .woff
and .eot
. Inside that zip file they had a demo.html
file that I just double clicked on and it opened up a web page in my browser showing me example usages of all the different css font options, how to implement them, and what they looked like etc.
@font-face
I still didn't know at this point how to include the fonts into my stylesheet properly using @font-face
but then I noticed that this demo.html
came with it's own stylesheet in the zip as well. I opened the stylesheet and it showed how to bring in all of the fonts using @font-face
so I was able to quickly, and easily, copy paste this into my project -
@font-face {

The demo.html
also had it's own inline stylesheet that was interesting to take a look at, though I am familiar with working with font weights and styles once they are included so I didn't need it much. For an example of how to implement a font style onto an html element for reference purposes you could use the following method in a similar case to mine after @font-face
has been used properly -
html, body{
margin: 0;
font-family: 'Open Sans';
}
.banner h1{
font-size: 43px;
font-weight: 700;
}
.banner p{
font-size: 24px;
font-weight: 300;
font-style: italic;
}
Just had the same issue. Wanted to dynamically trigger parametrized downstream jobs based on the outcome of some groovy scripting.
Unfortunately on our Jenkins it's not possible to run System Groovy scripts. Therefore I had to do a small workaround:
Run groovy script which creates a properties file where the environment variable to be set is specified
def props = new File("properties.text")
if (props.text == 'foo=bar') {
props.text = 'foo=baz'
} else {
props.text = 'foo=bar'
}
Use env inject plugin to inject the variable written into this script
Inject environment variable
Property file path: properties.text
After that I was able to use the variable 'foo' as parameter for the parametrized trigger plugin. Some kind of workaround. But works!
I was so exasperated by many misleading articles and answers that I wrote my own RSS reader: https://gouessej.wordpress.com/2020/06/28/comment-creer-un-lecteur-rss-en-javascript-how-to-create-a-rss-reader-in-javascript/
You can use AJAX requests to fetch the RSS files but it will work if and only if you use a CORS proxy. I'll try to write my own CORS proxy to give you a more robust solution. In the meantime, it works, I deployed it on my server under Debian Linux.
My solution doesn't use JQuery, I use only plain Javascript standard APIs with no third party libraries and it's supposed to work even with Microsoft Internet Explorer 11.
Refer the scripts inside the angular-cli.json
(angular.json
when using angular 6+) file.
"scripts": [
"../path"
];
then add in typings.d.ts
(create this file in src
if it does not already exist)
declare var variableName:any;
Import it in your file as
import * as variable from 'variableName';
Use DATE_ADD function
DATE_ADD(datecolumn, INTERVAL 30 MINUTE);
In addition to the recommended steps in the Vlasec answer, you can use:
/{pageId}?fields=access_token&access_token=THE_ACCESS_TOKEN_PROVIDED_BY_GRAPH_EXPLORER
We had the same issue with our ClickOnce application that uses Interop with Microsoft Office. It happened only on a few computers in the company.
The best fix we found out was to modify MS Office installation on problematic computers (through the Programs and Features panel) and ensure that ".NET programmability feature" (not sure of the name of the component - our Microsoft_Office versions are not English) was installed for each of the MS Office applications (Excel, Word, Outlook, etc.). This seems to not be included in a default install.
Then the problem with stdole.dll was fixed.
I hope this might help.
A few tips in order
npm install typescript -g
If it still doesn't work run npm config get prefix
to see where npm install -g is putting files (append bin
to the output) and make sure that they are in the path (the node js setup does this. Maybe you forgot to tick that option).
Use @SessionAttributes
See the docs: Using @SessionAttributes to store model attributes in the HTTP session between requests
"Understanding Spring MVC Model And Session Attributes" also gives a very good overview of Spring MVC sessions and explains how/when @ModelAttribute
s are transferred into the session (if the controller is @SessionAttributes
annotated).
That article also explains that it is better to use @SessionAttributes
on the model instead of setting attributes directly on the HttpSession because that helps Spring MVC to be view-agnostic.
You need a click listener which calls addActivityItem
if less than 2 options exist:
var activities = document.getElementById("activitySelector");
activities.addEventListener("click", function() {
var options = activities.querySelectorAll("option");
var count = options.length;
if(typeof(count) === "undefined" || count < 2)
{
addActivityItem();
}
});
activities.addEventListener("change", function() {
if(activities.value == "addNew")
{
addActivityItem();
}
});
function addActivityItem() {
// ... Code to add item here
}
A live demo is here on JSfiddle.
See an example here: http://www.cplusplus.com/reference/stl/vector/insert/ eg.:
...
vector::iterator iterator1;
iterator1= vec1.begin();
vec1.insert ( iterator1+i , vec2[i] );
// This means that at position "i" from the beginning it will insert the value from vec2 from position i
Your first approach was replacing the values from vec1[i] with the values from vec2[i]
I had the same error. I cleaned the maven project then the problem was solved.
This error comes when there's incompatibility between node version and angular/cli version. therefore use below command to update the cli version to latest
npm install -g @angular/cli@latest
You can also just add an ON CONFLICT REPLACE clause to your user_name unique constraint and then just INSERT away, leaving it to SQLite to figure out what to do in case of a conflict. See:https://sqlite.org/lang_conflict.html.
Also note the sentence regarding delete triggers: When the REPLACE conflict resolution strategy deletes rows in order to satisfy a constraint, delete triggers fire if and only if recursive triggers are enabled.
Alternative solution using generic algorithms and Boost.Tokenizer:
struct ToInt
{
int operator()(string const &str) { return atoi(str.c_str()); }
};
string values = "1,2,3,4,5,9,8,7,6";
vector<int> ints;
tokenizer<> tok(values);
transform(tok.begin(), tok.end(), back_inserter(ints), ToInt());
In my case this was happening because org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.dataSource is an autowired field without a Qualifier and I am using multiple datasources with qualified names. I solved this problem by using @Primary arbitrarily on one of my dataSource bean configurations like so
@Primary
@Bean(name="oneOfManyDataSources")
public DataSource dataSource() { ... }
I suppose they want you to implement AbstractRoutingDataSource, and then that auto configuration will just work because no qualifier is needed, you just have a single data source that allows your beans to resolve to the appropriate DataSource as needed. Then you don't need the @Primary or @Qualifier annotations at all, because you just have a single DataSource.
In any case, my solution worked because my beans specify DataSource by qualifier, and the JPA auto config stuff is happy because it has a single primary DataSource. I am by no means recommending this as the "right" way to do things, but in my case it solved the problem quickly and did not deter the behavior of my application in any noticeable manner. Will hopefully one day get around to implementing the AbstractRoutingDataSource and refactoring all the beans that need a specific DataSource and then perhaps that will be a neater solution.
In order to use gets
safely, you have to know exactly how many characters you will be reading, so that you can make your buffer large enough. You will only know that if you know exactly what data you will be reading.
Instead of using gets
, you want to use fgets
, which has the signature
char* fgets(char *string, int length, FILE * stream);
(fgets
, if it reads an entire line, will leave the '\n'
in the string; you'll have to deal with that.)
It remained an official part of the language up to the 1999 ISO C standard, but it was officially removed by the 2011 standard. Most C implementations still support it, but at least gcc issues a warning for any code that uses it.
For C# the solution is to cast the values to a double (as Math.Ceiling takes a double):
int nPages = (int)Math.Ceiling((double)nItems / (double)nItemsPerPage);
In java you should do the same with Math.ceil().
The error you gave is due to the fact that in python, dictionary keys must be immutable types (if key can change, there will be problems), and list is a mutable type.
Your error says that you try to use a list as dictionary key, you'll have to change your list into tuples if you want to put them as keys in your dictionary.
According to the python doc :
The only types of values not acceptable as keys are values containing lists or dictionaries or other mutable types that are compared by value rather than by object identity, the reason being that the efficient implementation of dictionaries requires a key’s hash value to remain constant
Check your imports. There could be two classes with the same name. Either from your code or from a library you are using. Personally that was the issue.
If anyone still has this issue - you don't have to change compileSdkVersion
, this just defeats the whole purpose of support libraries.
Instead, use these in your gradle.build
file:
compile 'com.android.support:cardview-v7:+'
compile 'com.android.support:recyclerview-v7:+'
compile 'com.android.support:palette-v7:+'`

You can fix this by adding this:

if you want to change the text of "input",use:
`$("#inputId").val("what you want to put")`
and if you want to change the text in "label","span","div", you can use

A solution using the curses module. Printing a numeric value corresponding to each key pressed:
import curses
def main(stdscr):
# do not wait for input when calling getch
stdscr.nodelay(1)
while True:
# get keyboard input, returns -1 if none available
c = stdscr.getch()
if c != -1:
# print numeric value

Here's how I've managed to solve this. It works on the premise that using a time reference between activity transitions will most likely provide adequate evidence that an app has been "backgrounded" or not.
First, I've used an android.app.Application instance (let's call it MyApplication) which has a Timer, a TimerTask, a constant to represent the maximum number of milliseconds that the transition from one activity to another could reasonably take (I went with a value of 2s), and a boolean to indicate whether or not the app was "in the background":
public class MyApplication extends Application {
private Timer mActivityTransitionTimer;
private TimerTask mActivityTransitionTimerTask;
public boolean wasInBackground;
private final long MAX_ACTIVITY_TRANSITION_TIME_MS = 2000;
...
The application also provides two methods for starting and stopping the timer/task:
public void startActivityTransitionTimer() {
this.mActivityTransitionTimer = new Timer();
this.mActivityTransitionTimerTask = new TimerTask() {
public void run() {
MyApplication.this.wasInBackground = true;
}
};
this.mActivityTransitionTimer.schedule(mActivityTransitionTimerTask,
MAX_ACTIVITY_TRANSITION_TIME_MS);
}
public void stopActivityTransitionTimer() {
if (this.mActivityTransitionTimerTask != null) {
this.mActivityTransitionTimerTask.cancel();
}
if (this.mActivityTransitionTimer != null) {
this.mActivityTransitionTimer.cancel();
}
this.wasInBackground = false;
}
The last piece of this solution is to add a call to each of these methods from the onResume() and onPause() events of all activities or, preferably, in a base Activity from which all of your concrete Activities inherit:
@Override
public void onResume()
{
super.onResume();
MyApplication myApp = (MyApplication)this.getApplication();
if (myApp.wasInBackground)
{
//Do specific came-here-from-background code
}
myApp.stopActivityTransitionTimer();
}
@Override
public void onPause()
{
super.onPause();
((MyApplication)this.getApplication()).startActivityTransitionTimer();
}
So in the case when the user is simply navigating between the activities of your app, the onPause() of the departing activity starts the timer, but almost immediately the new activity being entered cancels the timer before it can reach the max transition time. And so wasInBackground would be false.
On the other hand when an Activity comes to the foreground from the Launcher, device wake up, end phone call, etc., more than likely the timer task executed prior to this event, and thus wasInBackground was set to true.

The -i
flag probably doesn't work for you, because you followed an example for GNU sed while macOS uses BSD sed and they have a slightly different syntax.
All the other answers tell you how to correct the syntax to work with BSD sed. The alternative is to install GNU sed on your macOS with:
brew install gsed
and then use it instead of the sed
version shipped with macOS (note the g
prefix), e.g:
gsed -i 's/oldword/newword/' file1.txt
If you want GNU sed commands to be always portable to your macOS, you could prepend "gnubin" directory to your path, by adding something like this to your .bashrc
/.zshrc
file (run brew info gsed
to see what exactly you need to do):
export PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"
and from then on the GNU sed becomes your default sed and you can simply run:
sed -i 's/oldword/newword/' file1.txt
Simply just enter any of below in the command line,
ng --version
ORng v
ORng -v
The Output would be like,
Not only the Angular version but also the Node version is also mentioned there. I use Angular 6.
Here is a possible solution the solution #3 on my comments to blubill's answer:
yourscript.php
========================
<?php
$dir = '/home/user/Pictures';
$file_display = array('jpg', 'jpeg', 'png', 'gif');
if (file_exists($dir) == false)
{
echo 'Directory "', $dir, '" not found!';
}
else
{
$dir_contents = scandir($dir);
foreach ($dir_contents as $file)
{
$file_type = strtolower(end(explode('.', $file)));
if ($file !== '.' && $file !== '..' && in_array($file_type, $file_display) == true)
{
$name = basename($file);
echo "<img src='img.php?name={$name}' />";
}
}
}
?>
img.php
========================
<?php
$name = $_GET['name'];
$mimes = array
(
'jpg' => 'image/jpg',
'jpeg' => 'image/jpg',
'gif' => 'image/gif',
'png' => 'image/png'
);
$ext = strtolower(end(explode('.', $name)));
$file = '/home/users/Pictures/'.$name;
header('content-type: '. $mimes[$ext]);
header('content-disposition: inline; filename="'.$name.'";');
readfile($file);
?>
Assuming code.cpp
is the source code, the following will not throw errors:
make code
./code
Here the first command compiles the code and creates an executable with the same name, and the second command runs it. There is no need to specify g++
keyword in this case.
Combining two previous answers, for Rails 4.0.4 (and up, presumably), this suffices at the end of config/boot.rb
:
require 'rails/commands/server'
module Rails
class Server
def default_options
super.merge({Port: 10524})
end
end
end
When building a GET
request, there is no body to the request, but rather everything goes on the URL. To build a URL (and properly percent escaping it), you can also use URLComponents
.
var url = URLComponents(string: "https://www.google.com/search/")!
url.queryItems = [
URLQueryItem(name: "q", value: "War & Peace")
]
The only trick is that most web services need +
character percent escaped (because they'll interpret that as a space character as dictated by the application/x-www-form-urlencoded
specification). But URLComponents
will not percent escape it. Apple contends that +
is a valid character in a query and therefore shouldn't be escaped. Technically, they are correct, that it is allowed in a query of a URI, but it has a special meaning in application/x-www-form-urlencoded
requests and really should not be passed unescaped.
Apple acknowledges that we have to percent escaping the +
characters, but advises that we do it manually:
var url = URLComponents(string: "https://www.wolframalpha.com/input/")!
url.queryItems = [
URLQueryItem(name: "i", value: "1+2")
]
url.percentEncodedQuery = url.percentEncodedQuery?.replacingOccurrences(of: "+", with: "%2B")
This is an inelegant work-around, but it works, and is what Apple advises if your queries may include a +
character and you have a server that interprets them as spaces.
So, combining that with your sendRequest
routine, you end up with something like:
func sendRequest(_ url: String, parameters: [String: String], completion: @escaping ([String: Any]?, Error?) -> Void) {
var components = URLComponents(string: url)!
components.queryItems = parameters.map { (key, value) in
URLQueryItem(name: key, value: value)
}
components.percentEncodedQuery = components.percentEncodedQuery?.replacingOccurrences(of: "+", with: "%2B")
let request = URLRequest(url: components.url!)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, // is there data
let response = response as? HTTPURLResponse, // is there HTTP response
(200 ..< 300) ~= response.statusCode, // is statusCode 2XX
error == nil else { // was there no error, otherwise ...
completion(nil, error)
return
}
let responseObject = (try? JSONSerialization.jsonObject(with: data)) as? [String: Any]
completion(responseObject, nil)
}
task.resume()
}
And you'd call it like:
sendRequest("someurl", parameters: ["foo": "bar"]) { responseObject, error in
guard let responseObject = responseObject, error == nil else {
print(error ?? "Unknown error")
return
}
// use `responseObject` here
}
Personally, I'd use JSONDecoder
nowadays and return a custom struct
rather than a dictionary, but that's not really relevant here. Hopefully this illustrates the basic idea of how to percent encode the parameters into the URL of a GET request.
See previous revision of this answer for Swift 2 and manual percent escaping renditions.
You could also you Point2D Java API class:
public static double distance(double x1, double y1, double x2, double y2)
Example:
double distance = Point2D.distance(3.0, 4.0, 5.0, 6.0);
System.out.println("The distance between the points is " + distance);
This might be of some help: http://www.webmasterworld.com/forum83/200.htm
A relevant quote:
Most attempts to accomplish this were made by assigning the property and value: div{height:100%} - this alone will not work. The reason is that without a parent defined height, the div{height:100%;} has nothing to factor 100% percent of, and will default to a value of div{height:auto;} - auto is an "as needed value" which is governed by the actual content, so that the div{height:100%} will a=only extend as far as the content demands.
The solution to the problem is found by assigning a height value to the parent container, in this case, the body element. Writing your body stlye to include height 100% supplies the needed value.
html, body { margin:0; padding:0; height:100%; }
Use:

It's not well advertised, but git clean

If you have got a pre-commit task with husky running eslint
, please continue reading. I tried most of the answers about parserOptions
and parser
values where my actual issue was about the node version I was using.
My current node version was 12.0.0, but husky was using my nvm default version somehow (even though I didn't have nvm
in my system). This seems to be an issue with husky itself. So:
$HOME/.nvm
folder which was not deleted when I removed nvm
earlier.If you want to do it by ClassName you could do:
<script type="text/javascript">
function hideTd(className){
var elements;
if (document.getElementsByClassName)
{
elements = document.getElementsByClassName(className);
}
else
{
var elArray = [];
var tmp = document.getElementsByTagName(elements);
var regex = new RegExp("(^|\\s)" + className+ "(\\s|$)");
for ( var i = 0; i < tmp.length; i++ ) {
if ( regex.test(tmp[i].className) ) {
elArray.push(tmp[i]);
}
}
elements = elArray;
}
for(var i = 0, i < elements.length; i++) {
if( elements[i].textContent == ''){
elements[i].style.display = 'none';
}
}
}
</script>

Apart of larsmans answer (who is indeed correct), the exception in a call to a get() method, so the code you have posted is not the one that is causing the error.
One way to look at it is that the visitor pattern is a way of letting your clients add additional methods to all of your classes in a particular class hierarchy.
It is useful when you have a fairly stable class hierarchy, but you have changing requirements of what needs to be done with that hierarchy.
The classic example is for compilers and the like. An Abstract Syntax Tree (AST) can accurately define the structure of the programming language, but the operations you might want to do on the AST will change as your project advances: code-generators, pretty-printers, debuggers, complexity metrics analysis.
Without the Visitor Pattern, every time a developer wanted to add a new feature, they would need to add that method to every feature in the base class. This is particularly hard when the base classes appear in a separate library, or are produced by a separate team.
(I have heard it argued that the Visitor pattern is in conflict with good OO practices, because it moves the operations of the data away from the data. The Visitor pattern is useful in precisely the situation that the normal OO practices fail.)
This is a small program that will keep asking an input until required input is given.
we should keep the required number as a string, otherwise it may not work. input is taken as string by default
required_number = '18'
while True:
number = input("Enter the number\n")
if number == required_number:
print ("GOT IT")
break
else:
print ("Wrong number try again")
or you can use eval(input()) method
required_number = 18
while True:
number = eval(input("Enter the number\n"))
if number == required_number:
print ("GOT IT")
break
else:
print ("Wrong number try again")
I got this exception when I set url in query like "example.com/files/text.txt". Ive changed url to "http://example.com/files/text.txt" and this exception dissapeared.
There is no standard, so there is no guarantee. With that said, its common for the sitemap to be self labeled and on the root, like this:
example.com/sitemap.xml
Case is sensitive on some servers, so keep that in mind. If its not there, look in the robots file on the root:
example.com/robots.txt
If you don't see it listed in the robots file head to Google and search this:
site:example.com filetype:xml
This will limit the results to XML files on your target domain. At this point its trial-and-error and based on the specifics of the website you are working with. If you get several pages of results from the Google search phrase above then try to limit the results further:
filetype:xml site:example.com inurl:sitemap
or
filetype:xml site:example.com inurl:products
If you still can't find it you can right-click > "View Source"
and do a search (aka: "control find" or Ctrl + F
) for .xml
to see if there is a reference to it in the code.
I had the same issue as the author, and ran into the issue with and without Anaconda and regardless of Python version. Everyone's environment is different, but after resolving it for myself I think that in some cases it may be due to having multiple version of Python installed. Each installed Python version has its own \Lib\site-packages\ folder which can contain a unique set of modules for that Python version, and where the IDE looks into folder path that doesn't have scikit-learn in it.
One way to try solve the issue: you might clear your system of all other Python versions and their cached/temp files/system variables, and then only have one version of Python installed anywhere. Then install the dependencies Numpy and Scipy, and finally Scikit-learn.
More detailed steps:
As some others have suggested, the key is making sure your environment is set up correctly where everything points to the correct library folder on your computer where the Sklearn package is located. There are a few ways this can be resolved. My approach was more drastic, but it turns out that I had a very messy Python setup on my system so I had to start fresh.

You need to start the Apache Tomcat services.
Win+R --> sevices.msc
Then, search for Apache Tomcat and right click on it and click on Start. This will start the service and then you'll be able to see Apache Tomcat homepage on the localhost
.
1) Correct
2) You can think of that one as "read only" list, where you don't care about the type of the items.Could e.g. be used by a method that is returning the length of the list.
3) T, E and U are the same, but people tend to use e.g. T for type, E for Element, V for value and K for key. The method that compiles says that it took an array of a certain type, and returns an array of the same type.
4) You can't mix oranges and apples. You would be able to add an Object to your String list if you could pass a string list to a method that expects object lists. (And not all objects are strings)
I found more accurate way to adding views like linear layouts in kotlin (Pass parent layout in inflate() and false)
val parentLayout = view.findViewById<LinearLayout>(R.id.llRecipientParent)
val childView = layoutInflater.inflate(R.layout.layout_recipient, parentLayout, false)
parentLayout.addView(childView)
As long as you specify a width on the element, it should wrap itself without needing anything else.
A clean and rebuild worked for me!
It is important to define an id in the model
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Model(model => model.Id(p => p.id))
)
I think that it's not supported. If you have a look at this DefaultValueAccessor
directive (see https://github.com/angular/angular/blob/master/modules/angular2/src/common/forms/directives/default_value_accessor.ts#L23). You will see that the value used to update the bound element is $event.target.value
.
This doesn't apply in the case of inputs with type file
since the file object can be reached $event.srcElement.files
instead.
For more details, you can have a look at this plunkr: https://plnkr.co/edit/ozZqbxIorjQW15BrDFrg?p=info:
@Component({
selector: 'my-app',
template: `
<div>
<input type="file" (change)="onChange($event)"/>
</div>
`,
providers: [ UploadService ]
})
export class AppComponent {
onChange(event) {
var files = event.srcElement.files;
console.log(files);
}
}
I have gone through the same problem when I was using
myApp.controller('mainController', ['$scope', function($scope,) {
//$http was not working in this
}]);
I have changed the above code to given below. Remember to include $http(2 times) as given below.
myApp.controller('mainController', ['$scope','$http', function($scope,$http) {
//$http is working in this
}]);
and It has worked well.
I think you can use GetState(); It can return the exact state of a thread.
One thing to note:
I have had issues with websockets and corporate firewalls. (Using HTTPS helps but not always.)
See https://github.com/LearnBoost/socket.io/wiki/Socket.IO-and-firewall-software https://github.com/sockjs/sockjs-client/issues/94
I assume there aren't as many issues with Server-Sent Events. But I don't know.
That said, WebSockets are tons of fun. I have a little web game that uses websockets (via Socket.IO) (http://minibman.com)
Pass a ref
if you want to change what the object is:
TestRef t = new TestRef();
t.Something = "Foo";
DoSomething(ref t);
void DoSomething(ref TestRef t)
{
t = new TestRef();
t.Something = "Not just a changed t, but a completely different TestRef object";
}
After calling DoSomething, t
does not refer to the original new TestRef
, but refers to a completely different object.
This may be useful too if you want to change the value of an immutable object, e.g. a string
. You cannot change the value of a string
once it has been created. But by using a ref
, you could create a function that changes the string for another one that has a different value.
It is not a good idea to use ref
unless it is needed. Using ref
gives the method freedom to change the argument for something else, callers of the method will need to be coded to ensure they handle this possibility.
Also, when the parameter type is an object, then object variables always act as references to the object. This means that when the ref
keyword is used you've got a reference to a reference. This allows you to do things as described in the example given above. But, when the parameter type is a primitive value (e.g. int
), then if this parameter is assigned to within the method, the value of the argument that was passed in will be changed after the method returns:
int x = 1;
Change(ref x);
Debug.Assert(x == 5);
WillNotChange(x);
Debug.Assert(x == 5); // Note: x doesn't become 10
void Change(ref int x)
{
x = 5;
}
void WillNotChange(int x)
{
x = 10;
}
My goal was to make a CUDA enabled docker image without using nvidia/cuda as base image. Because I have some custom jupyter image, and I want to base from that.
The host machine had nvidia driver, CUDA toolkit, and nvidia-container-toolkit already installed. Please refer to the official docs, and to Rohit's answer.
Test that nvidia driver and CUDA toolkit is installed correctly with: nvidia-smi
on the host machine, which should display correct "Driver Version" and "CUDA Version" and shows GPUs info.
Test that nvidia-container-toolkit is installed correctly with: docker run --rm --gpus all nvidia/cuda:latest nvidia-smi
I found what I assume to be the official Dockerfile for nvidia/cuda here I "flattened" it, appended the contents to my Dockerfile and tested it to be working nicely:

The difference between text/xml and application/xml is the default character encoding if the charset parameter is omitted:
Text/xml and application/xml behave differently when the charset parameter is not explicitly specified. If the default charset (i.e., US-ASCII) for text/xml is inconvenient for some reason (e.g., bad web servers), application/xml provides an alternative (see "Optional parameters" of application/xml registration in Section 3.2).
For text/xml:
Conformant with [RFC2046], if a text/xml entity is received with the charset parameter omitted, MIME processors and XML processors MUST use the default charset value of "us-ascii"[ASCII]. In cases where the XML MIME entity is transmitted via HTTP, the default charset value is still "us-ascii".
For application/xml:
If an application/xml entity is received where the charset parameter is omitted, no information is being provided about the charset by the MIME Content-Type header. Conforming XML processors MUST follow the requirements in section 4.3.3 of [XML] that directly address this contingency. However, MIME processors that are not XML processors SHOULD NOT assume a default charset if the charset parameter is omitted from an application/xml entity.
So if the charset parameter is omitted, the character encoding of text/xml is US-ASCII while with application/xml the character encoding can be specified in the document itself.
Now a rule of thumb on the internet is: “Be strict with the output but be tolerant with the input.” That means make sure to meet the standards as much as possible when delivering data over the internet. But build in some mechanisms to overlook faults or to guess when receiving and interpreting data over the internet.
So in your case just pick one of the two types (I recommend application/xml) and make sure to specify the used character encoding properly (I recommend to use the respective default character encoding to play safe, so in case of application/xml use UTF-8 or UTF-16).
An other way to get only the filename without querystring is by using parse_url and basename functions :
$parts = parse_url("http://example.com/foo/bar/baz/file.php?a=b&c=d");
$filename = basename($parts["path"]); // this will return 'file.php'
ssize_t
is not included in the standard and isn't portable. size_t
should be used when handling the size of objects (there's ptrdiff_t
too, for pointer differences).
That means that the definition of your function is not present in your program. You forgot to add that one.cpp
to your program.
What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp
to the project.
In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp
is missing.
For whats its worth here is my standard answer. The only thing new here is that is uses the Collections.reverseOrder(). Plus it puts all suggestions into one example:
/*
** Use the Collections API to sort a List for you.
**
** When your class has a "natural" sort order you can implement
** the Comparable interface.
**
** You can use an alternate sort order when you implement
** a Comparator for your class.
*/
import java.util.*;
public class Person implements Comparable<Person>
{
String name;
int age;
public Person(String name, int age)
{
this.name = name;
this.age = age;
}
public String getName()
{
return name;
}
public int getAge()
{
return age;
}

{
return name + " : " + age;
}
/*
** Implement the natural order for this class
*/
public int compareTo(Person p)
{
return getName().compareTo(p.getName());
}
static class AgeComparator implements Comparator<Person>
{
public int compare(Person p1, Person p2)
{
int age1 = p1.getAge();
int age2 = p2.getAge();
if (age1 == age2)
return 0;
else if (age1 > age2)
return 1;
else
return -1;
}
}
public static void main(String[] args)

List<Person> people = new ArrayList<Person>();
people.add( new Person("Homer", 38) );
people.add( new Person("Marge", 35) );

people.add( new Person("Lisa", 13) );
// Sort by natural order
Collections.sort(people);
System.out.println("Sort by Natural order");
System.out.println("\t" + people);
// Sort by reverse natural order
Collections.sort(people, Collections.reverseOrder());
System.out.println("Sort by reverse natural order");
System.out.println("\t" + people);
// Use a Comparator to sort by age
Collections.sort(people, new Person.AgeComparator());
System.out.println("Sort using Age Comparator");
System.out.println("\t" + people);
// Use a Comparator to sort by descending age
Collections.sort(people,
Collections.reverseOrder(new Person.AgeComparator()));
System.out.println("Sort using Reverse Age Comparator");
System.out.println("\t" + people);
}
}

Date
has the time part, so we only need to extract it from Date
I personally prefer the default format
parameter of the Date
when date and time needs to be separated instead of using the extra SimpleDateFormat
Date date = new Date()
String datePart = date.format("dd/MM/yyyy")
String timePart = date.format("HH:mm:ss")
println "datePart : " + datePart + "\ttimePart : " + timePart
I had the same warning and found that removing an unused @id got rid of the warning. For me it was obvious as the @id was associated with a growing list of textViews linked to a database, so there was a warning for each entry.

According to Google's Machine Learning Glossary, an epoch is defined as
"A full training pass over the entire dataset such that each example has been seen once. Thus, an epoch represents N/batch_size
training iterations, where N is the total number of examples."
If you are training model for 10 epochs with batch size 6, given total 12 samples that means:
the model will be able to see whole dataset in 2 iterations ( 12 / 6 = 2) i.e. single epoch.
overall, the model will have 2 X 10 = 20 iterations (iterations-per-epoch X no-of-epochs)
re-evaluation of loss and model parameters will be performed after each iteration!
I agree with VinnyD that what you need to do is add "&" in front of your __get function, as to make it to return the needed result as a reference:
public function &__get ( $propertyname )
But be aware of two things:
1) You should also do
return &$something;
or you might still be returning a value and not a reference...
2) Remember that in any case that __get returns a reference this also means that the corresponding __set will NEVER be called; this is because php resolves this by using the reference returned by __get, which is called instead!
So:
$var = $object->NonExistentArrayProperty;
means __get is called and, since __get has &__get and return &$something, $var is now, as intended, a reference to the overloaded property...
$object->NonExistentArrayProperty = array();
works as expected and __set is called as expected...
But:
$object->NonExistentArrayProperty[] = $value;
or
$object->NonExistentArrayProperty["index"] = $value;
works as expected in the sense that the element will be correctly added or modified in the overloaded array property, BUT __set WILL NOT BE CALLED: __get will be called instead!
These two calls would NOT work if not using &__get and return &$something, but while they do work in this way, they NEVER call __set, but always call __get.
This is why I decided to return a reference
return &$something;
when $something is an array(), or when the overloaded property has no special setter method, and instead return a value
return $something;
when $something is NOT an array or has a special setter function.
In any case, this was quite tricky to understand properly for me! :)
Please check the log , you will get more detailed information .

Angular-ui comes with dialog directive.Use it and set templateurl to whatever page you want to include.That is the most elegant way and i have used it in my project as well. You can pass several other parameters for dialog as per need.
As I find it best to explain by example and none of the answers seem to do that...
A practical example of using reflections would be a Java Language Server written in Java or a PHP Language Server written in PHP, etc. Language Server gives your IDE abilities like autocomplete, jump to definition, context help, hinting types and more. In order to have all tag names (words that can be autocompleted) to show all the possible matches as you type the Language Server has to inspect everything about the class including doc blocks and private members. For that it needs a reflection of said class.
A different example would be a unit-test of a private method. One way to do so is to create a reflection and change the method's scope to public in the test's set-up phase. Of course one can argue private methods shouldn't be tested directly but that's not the point.
You really want to use at. It is exactly made for this purpose.
echo /usr/bin/the_command options | at now + 1 day
However if you don't have at, or your hosting company doesn't provide access to it, you could make a self-deleting cron entry.
Sadly, this will remove all your cron entries. However, if you only have one, this is fine.
0 0 2 12 * crontab -r ; /home/adm/bin/the_command options
The command crontab -r
removes your crontab entry. Luckily the rest of the command line will still execute.
WARNING: This is dangerous! It removes ALL cron entries. If you have many, this will remove them all, not just the one that has the "crontab -r" line!
If you have to deal with data that large you'll need to split it up into manageable chunks. It won't all fit into memory on any small computer. You can probably load a portion of the data from disk (whatever reasonably fits), perform your calculations and changes to it, store it to disk, then repeat until complete.
I had the same "TypeError: an integer is required" error message when attempting to write. Thanks, the .encode() solved it for me. I'm running python 3.4 on a Dell D530 running 32 bit Windows XP Pro.
I'm omitting the com port settings here:
>>>import serial
>>>ser = serial.Serial(5)
>>>ser.close()
>>>ser.open()
>>>ser.write("1".encode())
1
>>>
EditText ein=(EditText)findViewById(R.id.edittext1);
TextView t=new TextView(this);
t.setText("Your Text is="+ein.getText());
setContentView(t);
From the documentation, you do it like:
<div class="row">
<div class="col-md-6">left</div>
<div class="col-md-push-6">content needs to be right aligned</div>
</div>
You can do the same like this:
@Override
public FaqQuestions getFaqQuestionById(Long questionId) {
session = sessionFactory.openSession();
tx = session.beginTransaction();
FaqQuestions faqQuestions = null;
try {
faqQuestions = (FaqQuestions) session.get(FaqQuestions.class,
questionId);
Hibernate.initialize(faqQuestions.getFaqAnswers());
tx.commit();
faqQuestions.getFaqAnswers().size();
} finally {
session.close();
}
return faqQuestions;
}
Just use faqQuestions.getFaqAnswers().size()nin your controller and you will get the size if lazily intialised list, without fetching the list itself.
Do it with javascript and add a onClick
-attribute to your object
-element:
<object data="mysvg.svg" type="image/svg+xml" onClick="window.location.href='http://google.at';">
<span>Your browser doesn't support SVG images</span>
</object>
As a native and efficient approach, you don't need to use ord
or any loop over the characters. Just encode with ascii
and ignore the errors.
The following will just remove the non-ascii characters:
new_string = old_string.encode('ascii',errors='ignore')
Now if you want to replace the deleted characters just do the following:
final_string = new_string + b' ' * (len(old_string) - len(new_string))
No record matched means no record returned. There's no place for the "value" of 0 to go if no records are found. You could create a crazy UNION query to do what you want but much, much, much better simply to check the number of records in the result set.
You mean like:
String names[] = {"Ankit","Bohra","Xyz"};
But you can only do this in the same statement when you declare it
you can use moment js :
moment(date).format('mm')
example : moment('2019-10-29T21:08').format('mm') ==> 08
hope it helps someone
You can use format strings as well.
string time = DateTime.Now.ToString("hh:mm:ss"); // includes leading zeros
string date = DateTime.Now.ToString("dd/MM/yy"); // includes leading zeros
or some shortcuts if the format works for you
string time = DateTime.Now.ToShortTimeString();
string date = DateTime.Now.ToShortDateString();
Either should work.
You can manually upload the artifact's by clicking on upload artifacts button in the Nexus server and provide the necessary GAV properties for uploading(it's generally the file structure for storing the artifact)
I realise this is an old post, but in case it helps, you can apply this CSS to have IE11 draw a dotted outline for the focus indication of a <select>

color: inherit;
outline-style: dotted;

I didn't use it myself but heard of a simple tool (not a text editor) for this so it is definitely possible without setting up a programming environment (by installing octave or python).
A quick search hints that it was possible with total commander. (A lightweight tool with an easy point and click interface)
I would not be surprised if this still works, but I can't guarantee it.
and(re.search("bla_bla_pattern", str_item, re.IGNORECASE) == None)
is working.
When you called notify on the notification manager you gave it an id - that is the unique id you can use to access it later (this is from the notification manager:
notify(int id, Notification notification)
To cancel, you would call:
cancel(int id)
with the same id. So, basically, you need to keep track of the id or possibly put the id into a Bundle you add to the Intent inside the PendingIntent?
This question is a bit tricky before Jan 2013 and matplotlib 1.3.1 (Aug 2013), which is the oldest stable version you can find on matpplotlib website. But after that it is quite trivial.
Because present version of matplotlib.pylab.scatter
support assigning: array of colour name string, array of float number with colour map, array of RGB or RGBA.
this answer is dedicate to @Oxinabox's endless passion for correcting the 2013 version of myself in 2015.
you have two option of using scatter command with multiple colour in a single call.
as pylab.scatter
command support use RGBA array to do whatever colour you want;
back in early 2013, there is no way to do so, since the command only support single colour for the whole scatter point collection. When I was doing my 10000-line project I figure out a general solution to bypass it. so it is very tacky, but I can do it in whatever shape, colour, size and transparent. this trick also could be apply to draw path collection, line collection....
the code is also inspired by the source code of pyplot.scatter
, I just duplicated what scatter does without trigger it to draw.
the command pyplot.scatter
return a PatchCollection
Object, in the file "matplotlib/collections.py" a private variable _facecolors
in Collection
class and a method set_facecolors
.
so whenever you have a scatter points to draw you can do this:
# rgbaArr is a N*4 array of float numbers you know what I mean
# X is a N*2 array of coordinates
# axx is the axes object that current draw, you get it from
# axx = fig.gca()
# also import these, to recreate the within env of scatter command
import matplotlib.markers as mmarkers
import matplotlib.transforms as mtransforms
from matplotlib.collections import PatchCollection
import matplotlib.markers as mmarkers
import matplotlib.patches as mpatches
# define this function
# m is a string of scatter marker, it could be 'o', 's' etc..
# s is the size of the point, use 1.0
# dpi, get it from axx.figure.dpi
def addPatch_point(m, s, dpi):
marker_obj = mmarkers.MarkerStyle(m)
path = marker_obj.get_path()
trans = mtransforms.Affine2D().scale(np.sqrt(s*5)*dpi/72.0)
ptch = mpatches.PathPatch(path, fill = True, transform = trans)
return ptch
patches = []
# markerArr is an array of maker string, ['o', 's'. 'o'...]
# sizeArr is an array of size float, [1.0, 1.0. 0.5...]
for m, s in zip(markerArr, sizeArr):
patches.append(addPatch_point(m, s, axx.figure.dpi))
pclt = PatchCollection(
patches,
offsets = zip(X[:,0], X[:,1]),
transOffset = axx.transData)
pclt.set_transform(mtransforms.IdentityTransform())
pclt.set_edgecolors('none') # it's up to you
pclt._facecolors = rgbaArr
# in the end, when you decide to draw
axx.add_collection(pclt)
# and call axx's parent to draw_idle()
Let's face it: this one appears a lot when recording macros:
Range("X1").Select
Selection.Copy
Range("Y9).Select
Selection.Paste
While the only thing the person wants is:
Range("Y9").Value = Range("X1").Value
Therefore, instead of using copy-paste in VBA macros, I'd advise the following simple approach:
Destination_Range.Value = Source_Range.Value
For iPhone it works if you add also playsinline so:
<video width="320" height="240" autoplay loop muted playsinline>
<source src="movie.mp4" type="video/mp4" />
</video>
You can use your own code. You don't need to use the looping structure, if you don't want to use the looping structure as you said above. Only you have to focus to remove space or trim the String of the list.
If you are using java8 you can simply trim the String using the single line of the code:
myList = myList.stream().map(String :: trim).collect(Collectors.toList());
The importance of the above line is, in the future, you can use a List or set as well. Now you can use your own code:
if(myList.contains("A")){
//true
}else{
// false
}
for better readability you can convert the object to a json string as below:
console.log(obj, JSON.stringify(obj));
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify
var month = mydate.getMonth(); // month (in integer 0-11)
var year = mydate.getFullYear(); // year
Then all you would need to have is an array of months:
var months = ['Jan', 'Feb', 'Mar', ...];
And then to show it:
alert(months[month] + " " + year);
To remove all array elements irrespective of any given id, use this:
collection.update(
{ },
{ $pull: { 'contact.phone': { number: '+1786543589455' } } }
);
When you use toFixed
, it always returns the value as a string. This sometimes complicates the code. To avoid that, you can make an alternative method for Number.
Number.prototype.round = function(p) {
p = p || 10;
return parseFloat( this.toFixed(p) );
};
and use:
var n = 22 / 7; // 3.142857142857143
n.round(3); // 3.143
or simply:
(22/7).round(3); // 3.143
The right tool for that is to create a range with your limits and the corresponding names.
You can then use the vlookup()
function, with the 4th parameter set to True
to create a range lookup.
Note: my PC uses ;
as separator, yours might use ,
.
Adjust formula according to your regional settings.
Why don't you just right click on the table and then properties -> Storage and it would tell you the row count. You can use the below for row count in a view
SELECT SUM (row_count)
FROM sys.dm_db_partition_stats
WHERE object_id=OBJECT_ID('Transactions')
AND (index_id=0 or index_id=1)`
I had exactly the same issue: was cleaning up my folders, rearranging and moving files. I entered: git rm . and hit enter; and then felt my bowels loosen a bit. Luckily, I didn't type in git commit -m "" straightaway.
However, the following command
git checkout .
restored everything, and saved my life.

Here is a Swift 5 solution for downloading and saving an image or in general a file to the documents directory by using Alamofire
:
func dowloadAndSaveFile(from url: URL) {
let destination: DownloadRequest.DownloadFileDestination = { _, _ in
var documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
documentsURL.appendPathComponent(url.lastPathComponent)
return (documentsURL, [.removePreviousFile])
}
let request = SessionManager.default.download(url, method: .get, to: destination)
request.validate().responseData { response in
switch response.result {
case .success:
if let destinationURL = response.destinationURL {
print(destinationURL)
}
case .failure(let error):
print(error.localizedDescription)
}
}
}
function arrayColumn(arr, n) {_x000D_
return arr.map(x=> x[n]);_x000D_
}_x000D_
_x000D_
var twoDimensionalArray = [_x000D_
[1, 2, 3],_x000D_
[4, 5, 6],_x000D_
[7, 8, 9]_x000D_
];_x000D_
_x000D_
console.log(arrayColumn(twoDimensionalArray, 1));
_x000D_
You are doing everything right by using a to_date function and specifying the time. The time is there in the database. The trouble is just that when you select a column of DATE datatype from the database, the default format mask doesn't show the time. If you issue a
alter session set nls_date_format = 'dd/MON/yyyy hh24:mi:ss'
or something similar including a time component, you will see that the time successfully made it into the database.
@echo off
(echo this is in the first line) > xy.txt
(echo this is in the second line) >> xy.txt
exit
The two >>
means that the second line will be appended to the file (i.e. second line will start after the last line of xy.txt).
this is how the xy.txt
looks like:
this is in the first line
this is in the second line
Here is a adapted version that enables glob.glob
like functionality without using glob2
.
def find_files(directory, pattern='*'):
if not os.path.exists(directory):
raise ValueError("Directory not found {}".format(directory))
matches = []
for root, dirnames, filenames in os.walk(directory):
for filename in filenames:
full_path = os.path.join(root, filename)
if fnmatch.filter([full_path], pattern):
matches.append(os.path.join(root, filename))
return matches
So if you have the following dir structure
tests/files
+-- a0
¦ +-- a0.txt
¦ +-- a0.yaml
¦ +-- b0
¦ +-- b0.yaml
¦ +-- b00.yaml
+-- a1
You can do something like this
files = utils.find_files('tests/files','**/b0/b*.yaml')
> ['tests/files/a0/b0/b0.yaml', 'tests/files/a0/b0/b00.yaml']
Pretty much fnmatch
pattern match on the whole filename itself, rather than the filename only.
Please note I'm a beginner. If My solution is wrong, please feel free to correct and/or let me know. I may learn something new too.
My solution:
Change the downloadPath accordingly to where you want your file to be saved. Feel free to use the absolute path too for your usage.
Save the below as downloadFile.py.
Usage: python downloadFile.py url-of-the-file-to-download new-file-name.extension
Remember to add an extension!
Example usage: python downloadFile.py http://www.google.co.uk google.html
import requests
import sys
import os
def downloadFile(url, fileName):
with open(fileName, "wb") as file:
response = requests.get(url)
file.write(response.content)
scriptPath = sys.path[0]
downloadPath = os.path.join(scriptPath, '../Downloads/')
url = sys.argv[1]
fileName = sys.argv[2]
print('path of the script: ' + scriptPath)
print('downloading file to: ' + downloadPath)
downloadFile(url, downloadPath + fileName)
print('file downloaded...')
print('exiting program...')

It's not quite what you asked for, but
git log --graph --simplify-by-decoration --pretty=format:'%d' --all
does a pretty good job. It shows tags and remote branches as well. This may not be desirable for everyone, but I find it useful. --simplifiy-by-decoration
is the big trick here for limiting the refs shown.
I use a similar command to view my log. I've been able to completely replace my gitk
usage with it:
git log --graph --oneline --decorate --all
I use it by including these aliases in my ~/.gitconfig file:
[alias]
l = log --graph --oneline --decorate
ll = log --graph --oneline --decorate --branches --tags
lll = log --graph --oneline --decorate --all
Edit: Updated suggested log command/aliases to use simpler option flags.
In bootstrap you can use .text-center
to align center. also add .row
and .col-md-*
to your code.
align=
is deprecated,
Added .col-xs-*
for demo

For those who are reading this and want to use the new version of bootstrap (beta version), you can do the above in a simpler way, using Boostrap Flexbox utilities classes

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet" />
<div class="container footer">
<div class="d-flex justify-content-between">
<div class="p-1">
<p>Hello there</p>
</div>
<div class="p-1">
<a href="#" class="btn btn-warning" onclick="changeLook()">Re</a>
<a href="#" class="btn btn-warning" onclick="changeBack()">Rs</a>
</div>
<div class="p-1">
