You cannot change the order of columns in smaller screens but you can do that in large screens.
So change the order of your columns.
<!--Main Content-->
<div class="col-lg-9 col-lg-push-3">
</div>
<!--Sidebar-->
<div class="col-lg-3 col-lg-pull-9">
</div>
By default this displays the main content first.
So in mobile main content is displayed first.
By using col-lg-push
and col-lg-pull
we can reorder the columns in large screens and display sidebar on the left and main content on the right.
Working fiddle here.
You can use print_r to get human-readable output. But to display it as text we add "echo '';"
echo ''; print_r($row);
Cookies.set("example", "foo"); // Sample 1
Cookies.set("example", "foo", { expires: 7 }); // Sample 2
Cookies.set("example", "foo", { path: '/admin', expires: 7 }); // Sample 3
alert( Cookies.get("example") );
Cookies.remove("example");
Cookies.remove('example', { path: '/admin' }) // Must specify path if used when setting.
Of course, never fails. Found the solution about a minute after posting the above question... solution for those that may have had the same issue:
ContextWrapper.getFilesDir()
Found here.
Eliminating the arrows should be avoided. A solution that preserves the dropdown arrows is to first remove styles from the dropdown:
.myDropdown {
background-color: #yourbg;
border-style: none;
}
Then create div directly before the dropdown in your HTML:
<div class="myDiv"></div>
<select class="myDropdown...">...</select>
And style the div like this:
.myDiv {
background-color: #yourbg;
border-style: none;
position: absolute;
display: inline;
border: 1px solid #acolor;
}
Display inline will keep the div from going to a new line, position absolute removes it from the flow of the page. The end result is a nice clean underline you can style as you'd like, and your dropdown still behaves as the user would expect.
The statement def foo(client_id: str) -> list or bool:
when evaluated is equivalent to
def foo(client_id: str) -> list:
and will therefore not do what you want.
The native way to describe a "either A or B" type hint is Union (thanks to Bhargav Rao):
def foo(client_id: str) -> Union[list, bool]:
I do not want to be the "Why do you want to do this anyway" guy, but maybe having 2 return types isn't what you want:
If you want to return a bool to indicate some type of special error-case, consider using Exceptions instead. If you want to return a bool as some special value, maybe an empty list would be a good representation.
You can also indicate that None
could be returned with Optional[list]
Struggled with the same problem for some time. But after creating the directory structure src/main/java and putting the source(from the top of the package), it worked as expected.
The tutorial I tried with. After you execute gradle build
, you will have to be able to find classes
under build
directory.
In my case, stopping Proxifier fixed it. I added a rule to route any connections from vpnkit.exe
as Direct
and it now works.
Since the original question was about the SerializableAttribute, it should be noted that this attribute only applies when using the BinaryFormatter or SoapFormatter.
It is a bit confusing, unless you really pay attention to the details, as to when to use it and what its actual purpose is.
It has NOTHING to do with XML or JSON serialization.
Used with the SerializableAttribute are the ISerializable Interface and SerializationInfo Class. These are also only used with the BinaryFormatter or SoapFormatter.
Unless you intend to serialize your class using Binary or Soap, do not bother marking your class as [Serializable]. XML and JSON serializers are not even aware of its existence.
you can try this function for multi-purpose
function ManageData($table_name='',$condition=array(),$udata=array(),$is_insert=false){
$resultArr = array();
$ci = & get_instance();
if($condition && count($condition))
$ci->db->where($condition);
if($is_insert)
{
$ci->db->insert($table_name,$udata);
return 0;
}
else
{
$ci->db->update($table_name,$udata);
return 1;
}
}
You'll have to use an HttpServletRequestWrapper:
public void doFilter(final ServletRequest request, final ServletResponse response, final FilterChain chain) throws IOException, ServletException {
final HttpServletRequest httpRequest = (HttpServletRequest) request;
HttpServletRequestWrapper wrapper = new HttpServletRequestWrapper(httpRequest) {
@Override
public String getHeader(String name) {
final String value = request.getParameter(name);
if (value != null) {
return value;
}
return super.getHeader(name);
}
};
chain.doFilter(wrapper, response);
}
Depending on what you want to do you may need to implement other methods of the wrapper like getHeaderNames
for instance. Just be aware that this is trusting the client and allowing them to manipulate any HTTP header. You may want to sandbox it and only allow certain header values to be modified this way.
You must search date defend on how you insert that game_date data on your database.. for example if you inserted date value on long date or short.
SELECT * FROM hockey_stats WHERE game_date >= "6/11/2018" AND game_date <= "6/17/2018"
You can also use BETWEEN:
SELECT * FROM hockey_stats WHERE game_date BETWEEN "6/11/2018" AND "6/17/2018"
simple as that.
The official way to set the disabled
attribute on an HTMLInputElement
is this:
var input = document.querySelector('[name="myButton"]');
// Without querySelector API
// var input = document.getElementsByName('myButton').item(0);
// disable
input.setAttribute('disabled', true);
// enable
input.removeAttribute('disabled');
While @kaushar's answer is sufficient for enabling and disabling an HTMLInputElement
, and is probably preferable for cross-browser compatibility due to IE's historically buggy setAttribute
, it only works because Element
properties shadow Element
attributes. If a property is set, then the DOM uses the value of the property by default rather than the value of the equivalent attribute.
There is a very important difference between properties and attributes. An example of a true HTMLInputElement
property is input.value
, and below demonstrates how shadowing works:
var input = document.querySelector('#test');_x000D_
_x000D_
// the attribute works as expected_x000D_
console.log('old attribute:', input.getAttribute('value'));_x000D_
// the property is equal to the attribute when the property is not explicitly set_x000D_
console.log('old property:', input.value);_x000D_
_x000D_
// change the input's value property_x000D_
input.value = "My New Value";_x000D_
_x000D_
// the attribute remains there because it still exists in the DOM markup_x000D_
console.log('new attribute:', input.getAttribute('value'));_x000D_
// but the property is equal to the set value due to the shadowing effect_x000D_
console.log('new property:', input.value);
_x000D_
<input id="test" type="text" value="Hello World" />
_x000D_
That is what it means to say that properties shadow attributes. This concept also applies to inherited properties on the prototype
chain:
function Parent() {_x000D_
this.property = 'ParentInstance';_x000D_
}_x000D_
_x000D_
Parent.prototype.property = 'ParentPrototype';_x000D_
_x000D_
// ES5 inheritance_x000D_
Child.prototype = Object.create(Parent.prototype);_x000D_
Child.prototype.constructor = Child;_x000D_
_x000D_
function Child() {_x000D_
// ES5 super()_x000D_
Parent.call(this);_x000D_
_x000D_
this.property = 'ChildInstance';_x000D_
}_x000D_
_x000D_
Child.prototype.property = 'ChildPrototype';_x000D_
_x000D_
logChain('new Parent()');_x000D_
_x000D_
log('-------------------------------');_x000D_
logChain('Object.create(Parent.prototype)');_x000D_
_x000D_
log('-----------');_x000D_
logChain('new Child()');_x000D_
_x000D_
log('------------------------------');_x000D_
logChain('Object.create(Child.prototype)');_x000D_
_x000D_
// below is for demonstration purposes_x000D_
// don't ever actually use document.write(), eval(), or access __proto___x000D_
function log(value) {_x000D_
document.write(`<pre>${value}</pre>`);_x000D_
}_x000D_
_x000D_
function logChain(code) {_x000D_
log(code);_x000D_
_x000D_
var object = eval(code);_x000D_
_x000D_
do {_x000D_
log(`${object.constructor.name} ${object instanceof object.constructor ? 'instance' : 'prototype'} property: ${JSON.stringify(object.property)}`);_x000D_
_x000D_
object = object.__proto__;_x000D_
} while (object !== null);_x000D_
}
_x000D_
I hope this clarifies any confusion about the difference between properties and attributes.
Below is the code for set the modal pop-up width and left position from the screen through javascript.
$('#openModalPopupId').css({ "width": "80%", "left": "30%"});
on arch linux. (im not sure on other distros) you can view the operstate. which shows up if connected or down if not the operstate lives on
/sys/class/net/(interface name here)/operstate
#you can also put watch
watch -d -n -1 /sys/class/net/(interface name here)/operstate
First up, going by the function name xssRequest it sounds like you're trying cross site request - which if that's right, you're not going to be able to read the contents of the iframe.
On the other hand, if the iframe's URL is on your domain you can access the body, but I've found that if I use a timeout to remove the iframe the callback works fine:
// possibly excessive use of jQuery - but I've got a live working example in production
$('#myUniqueID').load(function () {
if (typeof callback == 'function') {
callback($('body', this.contentWindow.document).html());
}
setTimeout(function () {$('#frameId').remove();}, 50);
});
// The interface
interface Blah {
void something();
}
...
// Something that expects an object implementing that interface
void chewOnIt(Blah b) {
b.something();
}
...
// Let's provide an object of an anonymous class
chewOnIt(
new Blah() {
@Override
void something() { System.out.println("Anonymous something!"); }
}
);
UPDATE: TensorFlow supports Python 3.6 on Windows since version 1.2.0 (see the release notes)
TensorFlow only supports Python 3.5 64-bit as of now. Support for Python 3.6 is a work in progress and you can track it here as well as chime in the discussion.
The only alternative to use Python 3.6 with TensorFlow on Windows currently is building TF from source.
If you don't want to uninstall your Anaconda distribution for Python 3.6 and install a previous release you can create a conda environment for Python=3.5 as in:
conda create --name tensorflow python=3.5
activate tensorflow
pip install tensorflow-gpu
You can change default options by using Chart.defaults.global
in your javascript file. So you want to change legend and tooltip options.
Chart.defaults.global.legend.display = false;
Chart.defaults.global.tooltips.enabled = false;

The problem may be that ssh is trying to connect to all the different IPs that www.google.com

If I run it with a specific IP, it returns much faster.

) and the results are:

I've fully tested it by changing the timezones on the emulator
There are many systems for week numbering. The following are the most common systems simply put with code examples:
ISO: First week starts with Monday and must contain the January 4th. The ISO calendar is already implemented in Python:
>>> from datetime import date
>>> date(2014, 12, 29).isocalendar()[:2]
(2015, 1)
North American: First week starts with Sunday and must contain the January 1st. The following code is my modified version of Python's ISO calendar implementation for the North American system:
from datetime import date
def week_from_date(date_object):
date_ordinal = date_object.toordinal()
year = date_object.year
week = ((date_ordinal - _week1_start_ordinal(year)) // 7) + 1
if week >= 52:
if date_ordinal >= _week1_start_ordinal(year + 1):
year += 1
week = 1
return year, week
def _week1_start_ordinal(year):
jan1 = date(year, 1, 1)
jan1_ordinal = jan1.toordinal()
jan1_weekday = jan1.weekday()
week1_start_ordinal = jan1_ordinal - ((jan1_weekday + 1) % 7)
return week1_start_ordinal
>>> from datetime import date
>>> week_from_date(date(2014, 12, 29))
(2015, 1)
>>> from datetime import date
>>> from epiweeks import Week
>>> Week.fromdate(date(2014, 12, 29))
(2014, 53)
The webdriver
will wait for a page to load by default via .get()
method.
As you may be looking for some specific element as @user227215 said, you should use WebDriverWait
to wait for an element located in your page:
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.common.exceptions import TimeoutException
browser = webdriver.Firefox()
browser.get("url")
delay = 3 # seconds
try:
myElem = WebDriverWait(browser, delay).until(EC.presence_of_element_located((By.ID, 'IdOfMyElement')))
print "Page is ready!"
except TimeoutException:
print "Loading took too much time!"
I have used it for checking alerts. You can use any other type methods to find the locator.
EDIT 1:
I should mention that the webdriver
will wait for a page to load by default. It does not wait for loading inside frames or for ajax requests. It means when you use .get('url')
, your browser will wait until the page is completely loaded and then go to the next command in the code. But when you are posting an ajax request, webdriver
does not wait and it's your responsibility to wait an appropriate amount of time for the page or a part of page to load; so there is a module named expected_conditions
.
I create equations with random numbers in VBA and for x squared put in x^2.
I read each square (or textbox) text into a string.
I then read each character in the string in turn and note the location of the ^ ("hats")'s in each.
Say the hats were at positions 4, 8 and 12.
I then "chop out" the first hat - the position of the character to be superscripted is now 4, the position of the other hats is now 7 and 11. I chop out the second hat, the character to superscript is now at 7 and the hat has moved to 10. I chop out the last hat .. the superscript character is now position 10.
I now select each character in turn and change the font to superscript.
Thus I can fill a whole spreadsheet with algebra using ^ and then call a routine to tidy it up.
For big powers like x to the 23 I build x^2^3 and the above routine does it.
As far as I know, Windows will not support shell scripts out of the box. You can install Cygwin or Git for Windows, go to Manage Jenkins > Configure System Shell and point it to the location of sh.exe file found in their installation. For example:
C:\Program Files\Git\bin\sh.exe
There is another option I've discovered. This one is better because it allowed me to use shell in pipeline scripts with simple sh "something"
.
Add the folder to system PATH. Right click on Computer, click properties > advanced system settings > environmental variables, add C:\Program Files\Git\bin\
to your system Path property.
IMPORTANT note: for some reason I had to add it to the system wide Path, adding to user Path didn't work, even though Jenkins was running on this user.
An important note (thanks bugfixr!):
This works. It should be noted that you will need to restart Jenkins in order for it to pick up the new PATH variable. I just went to my services and restated it from there.
Disclaimer: the names may differ slightly as I'm not using English Windows.
Try this first, you may be passing a Null Model:
@if (Model != null && !String.IsNullOrEmpty(Model.ImageName))
{
<label for="Image">Change picture</label>
}
else
{
<label for="Image">Add picture</label>
}
Otherise, you can make it even neater with some ternary fun! - but that will still error if your model is Null.
<label for="Image">@(String.IsNullOrEmpty(Model.ImageName) ? "Add" : "Change") picture</label>
Short version: Create styles only once, use them everywhere.
Long version: use a method to create the styles you need (beware of the limit on the amount of styles).
private static Map<String, CellStyle> styles;
private static Map<String, CellStyle> createStyles(Workbook wb){
Map<String, CellStyle> styles = new HashMap<String, CellStyle>();
DataFormat df = wb.createDataFormat();
CellStyle style;
Font headerFont = wb.createFont();
headerFont.setBoldweight(Font.BOLDWEIGHT_BOLD);
headerFont.setFontHeightInPoints((short) 12);
style = createBorderedStyle(wb);
style.setAlignment(CellStyle.ALIGN_CENTER);
style.setFont(headerFont);
styles.put("style1", style);
style = createBorderedStyle(wb);
style.setAlignment(CellStyle.ALIGN_CENTER);
style.setFillForegroundColor(IndexedColors.LIGHT_CORNFLOWER_BLUE.getIndex());
style.setFillPattern(CellStyle.SOLID_FOREGROUND);
style.setFont(headerFont);
style.setDataFormat(df.getFormat("d-mmm"));
styles.put("date_style", style);
...
return styles;
}
you can also use methods to do repetitive tasks while creating styles hashmap
private static CellStyle createBorderedStyle(Workbook wb) {
CellStyle style = wb.createCellStyle();
style.setBorderRight(CellStyle.BORDER_THIN);
style.setRightBorderColor(IndexedColors.BLACK.getIndex());
style.setBorderBottom(CellStyle.BORDER_THIN);
style.setBottomBorderColor(IndexedColors.BLACK.getIndex());
style.setBorderLeft(CellStyle.BORDER_THIN);
style.setLeftBorderColor(IndexedColors.BLACK.getIndex());
style.setBorderTop(CellStyle.BORDER_THIN);
style.setTopBorderColor(IndexedColors.BLACK.getIndex());
return style;
}
then, in your "main" code, set the style from the styles map you have.
Cell cell = xssfCurrentRow.createCell( intCellPosition );
cell.setCellValue( blah );
cell.setCellStyle( (CellStyle) styles.get("style1") );
Basically you use props to send information to and from Child and Parent.
Adding to all the wonderful answers, let me give a simple example that explains passing values from child to parent component in React
App.js
class App extends React.Component {
constructor(){
super();
this.handleFilterUpdate = this.handleFilterUpdate.bind(this);
this.state={name:'igi'}
}
handleFilterUpdate(filterValue) {
this.setState({
name: filterValue
});
}
render() {
return (
<div>
<Header change={this.handleFilterUpdate} name={this.state.name} />
<p>{this.state.name}</p>
</div>
);
}
}
Header.js
class Header extends React.Component {
constructor(){
super();
this.state={
names: 'jessy'
}
}
Change(event) {
// this.props.change(this.state.names);
this.props.change('jessy');
}
render() {
return (
<button onClick={this.Change.bind(this)}>click</button>
);
}
}
Main.js
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App.jsx';
ReactDOM.render(<App />, document.getElementById('app'));
Thats it , now you can pass values from your client to the server.
Take a look at the Change function in the Header.js
Change(event) {
// this.props.change(this.state.names);
this.props.change('jessy');
}
This is how you push values into the props from client to the server
What about this?
java.sql.Timestamp timestamp = java.sql.Timestamp.valueOf("2007-09-23 10:10:10.0");
While @perrejba s answer is correct, it uses the legacy C-style functions. As the question is tagged C++, you may want to use a method instead:
inputMat.copyTo(outputMat, maskMat);
All objects are of type cv::Mat
.
Please be aware that the masking is binary. Any non-zero value in the mask is interpreted as 'do copy'. Even if the mask is a greyscale image.
Also be aware that the .copyTo() function does not clear the output before copying.
If you want to permanently alter the original Image, you have to do an additional copy/clone/assignment. The copyTo() function is not defined for overlapping input/output images. So you can't use the same image as both input and output.

Here's my attempt. Excuse the fluff, I was feeling extra creative.
My method is a parent div
with fixed dimensions. The rest is just fitting the content inside that div accordingly.
This will rescale the images regardless of the aspect ratio. There will be no hard cropping either.

I have developed a light weighted library for android, you can visit https://github.com/ChathuraHettiarachchi/RecycleClick
and follow for following sample
RecycleClick.addTo(YOUR_RECYCLEVIEW).setOnItemClickListener(new RecycleClick.OnItemClickListener() {
@Override
public void onItemClicked(RecyclerView recyclerView, int position, View v) {
// YOUR CODE
}
});
VSCode is incredibly faster than VS. Files open instantly from Unity. VS is very slow. VSCode launches instantly. VS takes forever to launch.
VS can literally compile code, build apps and so on, it's a huge IDE like Unity itself or XCode. VSCode is indeed "just" a full-featured text editor. VSCode is NOT a compiler (far less a huge, build-everything system that can literally create apps and software of all types): VSCode is literally "just a text editor".
With VSCode, you DO need to install the "Visual Studio Code" package. (Not to be confused with the "Visual Studio" package.) (It seems to me that VS works fine without the VS package, but, with VS Code, you must install Unity's VSCode package.)
When you first download and install VSCode, simply open any C# file on your machine. It will instantly prompt you to install the needed C# package. This is harmless and easy.
Unfortunately VSCode generally has only one window! You cannot, really, easily drag files to separate windows. If this is important to you, you may need to go with VS.
The biggest problem with VS is that the overall concept of settings and preferences are absolutely horrible. In VS, it is all-but impossible to change the font, etc. In contrast, VSCode has FANTASTIC preferences - dead simple, never a problem.
As far as I can see, every single feature in VS which you use in Unity is present in VSCode. (So, code coloring, jump to definitions, it understands/autocompletes every single thing in Unity, it opens from Unity, double clicking something in the Unity console opens the file to that line, etc etc)
If you are used to VS. And you want to change to VSCode. It's always hard changing editors, they are so intimate, but it's pretty similar; you won't have a big heartache.
In short if you're a VS for Unity3D user,
and you're going to try VSCode...
VSCode is on the order of 19 trillion times faster in every way. It will blow your mind.
It does seem to have every feature.
Basically VS is the world's biggest IDE and application building system: VSCode is just an editor. (Indeed, that's exactly what you want with Unity, since Unity itself is the IDE.)
Don't forget to just click to install the relevant Unity package.
If I'm not mistaken, there is no reason whatsoever to use VS with Unity.
Unity is an IDE so you just need a text editor, and that is what VSCode is. VSCode is hugely better in both speed and preferences. The only possible problem - multiple-windows are a bit clunky in VSCode!
If you are using VS with Unity. There is an infuriating problem where often VS will try to open twice, that is you will end up with two or more copies of VS running. Nobody has ever been able to fix this or figure out what the hell causes it. Fortunately, this problem never happens with VSCode.
There are no installers, etc etc etc. On the download page, you download a zipped Mac app. Put it in the Applications folder and you're done.
Bizarrely there's no menu entry / docu whatsoever for folding, but here are the keys:

To keep the "Explorer" list of files on the left tidy, in the Unity case:
// Following is angular 2.0 directive for window re size that adjust scroll bar for give element as per your tag
---- angular 2.0 window resize directive.
import { Directive, ElementRef} from 'angular2/core';
@Directive({
selector: '[resize]',
host: { '(window:resize)': 'onResize()' } // Window resize listener
})
export class AutoResize {
element: ElementRef; // Element that associated to attribute.
$window: any;
constructor(_element: ElementRef) {
this.element = _element;
// Get instance of DOM window.
this.$window = angular.element(window);
this.onResize();
}
// Adjust height of element.
onResize() {
$(this.element.nativeElement).css('height', (this.$window.height() - 163) + 'px');
}
}
put following code in your page
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequest);
function EndRequest(sender, args) {
if (args.get_error() == undefined) {
$('.dropdown-toggle').dropdown();
}
}
You can check all the config settings using
git config --global --list
You can remove the setting for example username
git config --global --unset user.name
You can edit the configuration or remove the config setting manually by hand using:
git config --global --edit
I had an issue where I was doing commit --amend
even after issuing a git add .
and it still wasn't working. Turns out I made some .vimrc
customizations and my editor wasn't working correctly. Fixing these errors so that vim
returns the correct code resolved the issue.
Here is the correct SOLUTION! Since the button doesn't have a defined attribute type, angular maybe attempting to issue the keyup event as a submit request and triggers the click event on the button.
<button type="button" ...></button>
Big thanks to DeborahK!
Angular2 - Enter Key executes first (click) function present on the form
You can use Tersus (open source), and it lets you export the app as an Xcode project.
If you want to cut the whitespaces before and behind the word, but keep the middle ones.
You could use:
word = ' Hello World '
stripped = word.strip()
print(stripped)
I have an Android LG G4 and the only thing that worked for me was to install the Software Update and Repair tool from my device. Steps:
I did discover .NET has a built in way to cast the JSON string into a Dictionary<String, Object>
via the System.Web.Script.Serialization.JavaScriptSerializer
type in the 3.5 System.Web.Extensions
assembly. Use the method DeserializeObject(String)
.
I stumbled upon this when doing an ajax post (via jquery) of content type 'application/json' to a static .net Page Method and saw that the method (which had a single parameter of type Object
) magically received this Dictionary.
My answer may be late but it worked for me. It may help somebody.
I tried above mentioned steps and that didn't solved the issue.
try thisgit config --global http.sslVerify false
If you had a table that already had a existing constraints based on lets say: name and lastname and you wanted to add one more unique constraint, you had to drop the entire constrain by:
ALTER TABLE your_table DROP CONSTRAINT constraint_name;
Make sure tha the new constraint you wanted to add is unique/ not null ( if its Microsoft Sql, it can contain only one null value) across all data on that table, and then you could re-create it.
ALTER TABLE table_name
ADD CONSTRAINT constraint_name UNIQUE (column1, column2, ... column_n);
I wrote this script some time ago:
Usage:
var myCounter = new Countdown({
seconds:5, // number of seconds to count down
onUpdateStatus: function(sec){console.log(sec);}, // callback for each second
onCounterEnd: function(){ alert('counter ended!');} // final action
});
myCounter.start();
function Countdown(options) {
var timer,
instance = this,
seconds = options.seconds || 10,
updateStatus = options.onUpdateStatus || function () {},
counterEnd = options.onCounterEnd || function () {};
function decrementCounter() {
updateStatus(seconds);
if (seconds === 0) {
counterEnd();
instance.stop();
}
seconds--;
}
this.start = function () {
clearInterval(timer);
timer = 0;
seconds = options.seconds;
timer = setInterval(decrementCounter, 1000);
};
this.stop = function () {
clearInterval(timer);
};
}
Hope you are using Python 3 ,
Str are unicode by default, so please
Replace Unicode
function with String Str
function.
if isinstance(unicode_or_str, str): ##Replaces with str
text = unicode_or_str
decoded = False
There is no difference.
COUNT(1)
is basically just counting a constant value 1 column for each row. As other users here have said, it's the same as COUNT(0)
or COUNT(42)
. Any non-NULL
value will suffice.

The Oracle optimizer did apparently use to have bugs in it, which caused the count to be affected by which column you picked and whether it was in an index, so the COUNT(1) convention came into being.
Modify cmd.exe properties using the command prompt Pretty much has what you're asking for. More on the topic, mode con: cols=160 lines=78
should achieve what you want.
Change 160 and 78 to your values.
Use the length
property of the [String]
type:
if ($dbUserName.length -gt 8) {
Write-Output "Please enter more than 8 characters."
$dbUserName = Read-Host "Re-enter database username"
}
Please note that you have to use -gt
instead of >
in your if
condition. PowerShell uses the following comparison operators to compare values and test conditions:
Here's a one line solution without a while loop.
The order is preserved in the resulting list.
The potential downsides are
let re = /\s*([^[:]+):\"([^"]+)"/g
let str = '[description:"aoeu" uuid:"123sth"]'
(str.match(re) || []).map(e => RegExp(re.source, re.flags).exec(e))
[ [ 'description:"aoeu"',
'description',
'aoeu',
index: 0,
input: 'description:"aoeu"',
groups: undefined ],
[ ' uuid:"123sth"',
'uuid',
'123sth',
index: 0,
input: ' uuid:"123sth"',
groups: undefined ] ]
maybe this can solve the problem: matplotlib, define size of a grid on a plot
ax.grid(True, which='both')
The truth is that the grid is working, but there's only one v-grid in 00:00 and no grid in others. I meet the same problem that there's only one grid in Nov 1 among many days.
Using %lf
will help you in solving this problem.
Use :
scanf("%lf",&doub)
One practice case is when you are working with Bitbucket PR. There is PR open.
Then you decide to rebase the PR remote branch on the latest Master branch. This will change the commit's ids of your PR.
Then you want to add a new commit to the PR branch.
Since you have rebased the remote branch using GUI first you to sync the local branch on PC with the remote branch.
In this case git pull --rebase
works like magic.
After git pull --rebase
your remote branch and local branch has same history with same commit ids.
Now you can nicely push a new commit without using force or anything.
You can use EXCEPT
syntax, for example:
SELECT var FROM table1
EXCEPT
SELECT var FROM table2
In order to execute multiple programs, I also needed a profiles
section:
<profiles>
<profile>
<id>traverse</id>
<activation>
<property>
<name>traverse</name>
</property>
</activation>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<configuration>
<executable>java</executable>
<arguments>
<argument>-classpath</argument>
<argument>org.dhappy.test.NeoTraverse</argument>
</arguments>
</configuration>
</plugin>
</plugins>
</build>
</profile>
</profiles>
This is then executable as:
mvn exec:exec -Ptraverse
You can use StringBuilder:
StringBuilder sb = new StringBuilder();
sb.append('a');
sb.append('b');
sb.append('c');
String str = sb.toString()
Or if you already have the characters, you can pass a character array to the String constructor:
String str = new String(new char[]{'a', 'b', 'c'});
My site configuration file is example.conf in sites-available folder So you can create a symbolic link as
ln -s /etc/nginx/sites-available/example.conf /etc/nginx/sites-enabled/
If you want more Thread to be created, in above case you have to repeat the code inside run method or at least repeat calling some method inside.
Try this, which will help you to call as many times you needed. It will be helpful when you need to execute your run more then once and from many place.
class A extends Thread {
public void run() {
//Code you want to get executed seperately then main thread.
}
}
Main class
A obj1 = new A();
obj1.start();
A obj2 = new A();
obj2.start();
Avoid of lot of fat fingering by starting with a Dictionary in the Model
namespace EzPL8.Models
{
public class MyEggs
{
public Dictionary<int, string> Egg { get; set; }
public MyEggs()
{
Egg = new Dictionary<int, string>()
{
{ 0, "No Preference"},
{ 1, "I hate eggs"},
{ 2, "Over Easy"},
{ 3, "Sunny Side Up"},
{ 4, "Scrambled"},
{ 5, "Hard Boiled"},
{ 6, "Eggs Benedict"}
};
}
}
In the View convert it to a list for display
@Html.DropDownListFor(m => m.Egg.Keys,
new SelectList(
Model.Egg,
"Key",
"Value"))
Using the below line
SELECT LEFT(subject , 10) FROM tbl
import sys, os
try:
raise NotImplementedError("No error")
except Exception as e:
exc_type, exc_obj, exc_tb = sys.exc_info()
fname = os.path.split(exc_tb.tb_frame.f_code.co_filename)[1]
print(exc_type, fname, exc_tb.tb_lineno)
If the application you are generating the scripts from is a .NET application, you may want to look into using SMO (Sql Management Objects). Reference this SQL Team link on how to use SMO to script objects.
You need to multiply your Model matrix. Because that is where model position, scaling and rotation should be (that's why it's called the model matrix).
All you need to do is (see here)
Model = glm::rotate(Model, angle_in_radians, glm::vec3(x, y, z)); // where x, y, z is axis of rotation (e.g. 0 1 0)
Note that to convert from degrees to radians, use
glm::radians(degrees)
That takes the Model matrix and applies rotation on top of all the operations that are already in there. The other functions translate and scale do the same. That way it's possible to combine many transformations in a single matrix.
note: earlier versions accepted angles in degrees. This is deprecated since 0.9.6
Model = glm::rotate(Model, angle_in_degrees, glm::vec3(x, y, z)); // where x, y, z is axis of rotation (e.g. 0 1 0)
Here is an example from the matplotlib tutorial found here. This is one of the more simpler examples but I added transparency to the legend and added plt.show() so you can paste this into the interactive shell and get a result:
import matplotlib.pyplot as plt
p1, = plt.plot([1, 2, 3])
p2, = plt.plot([3, 2, 1])
p3, = plt.plot([2, 3, 1])
plt.legend([p2, p1, p3], ["line 1", "line 2", "line 3"]).get_frame().set_alpha(0.5)
plt.show()
I had used some of the above solutions but it was working for width
but height
.
compileSdkVersion
greater than 23, you can directly use RecyclerView provided in their respective support libraries of recycler view, like for 23 it will be 'com.android.support:recyclerview-v7:23.2.1'
. These support libraries support attributes of wrap_content
for both width and height.You have to add it to your dependencies
compile 'com.android.support:recyclerview-v7:23.2.1'
compileSdkVersion
less than 23, you can use below-mentioned solution.I found this Google thread regarding this issue. In this thread, there is one contribution which leads to the implementation of LinearLayoutManager.
I have tested it for both height and width and it worked fine for me in both cases.

so long as your html content doesn't need to contain a CDATA
element, you can contain the HTML in a CDATA
element, otherwise you'll have to escape the XML entities.
<element><![CDATA[<p>your html here</p>]]></element>
VS
<element><p>your html here</p></element>
In Java x ^ y
is an XOR
operation.
If you want to call your filter inside ng-options the code will be as follows:
ng-options="productSize as ( productSize | sizeWithPrice: product ) for productSize in productSizes track by productSize.id"
where the filter is sizeWithPriceFilter and it has two parameters product and productSize
In another way, you can also make the two column primary key unique
and the auto-increment key primary
. Just like this: https://stackoverflow.com/a/6157337
If this happens and you are using Let's Encrypt / certbot, the reason is most likely that you used chain.pem
instead of fullchain.pem
.
It should be something like this:
ssl_certificate /etc/certbot/live/example.com/fullchain.pem;
ssl_certificate_key /etc/certbot/live/example.com/privkey.pem;
Well, your syntax doesn't match the link you included, which specifies:
CREATE TABLE name (column defs)
CONSTRAINT constraint_name -- This is new
UNIQUE (col_name1, col_name2) ON CONFLICT REPLACE
Root problem is a ReferenceError
. MDN indicates that a try
/catch
block is the proper tool for the job. In my case, I was getting uncaught reference error for a payment sdk/library. The below works for me.
try {
var stripe = Stripe('pk_test_---------');
} catch (e) {
stripe = null;
}
if(stripe){
//we are good to go now
}
Obviously the fix is to load whatever SDK/library, e.g. jQuery, prior to calling its methods but the try
/catch
does keep your shared JavaScript from barfing up errors in case you run that shared script on a page that doesn't load whatever library you use on a subset of pages.
Date and time formats are well described below
SimpleDateFormat (Java Platform SE 7) - Date and Time Patterns
There could be n
Number of formats you can possibly make. ex - dd/MM/yyyy
or YYYY-'W'ww-u
or you can mix and match the letters to achieve your required pattern. Pattern letters are as follow.
G
- Era designator (AD)y
- Year (1996; 96)Y
- Week Year (2009; 09)M
- Month in year (July; Jul; 07)w
- Week in year (27)W
- Week in month (2)D
- Day in year (189)d
- Day in month (10)F
- Day of week in month (2)E
- Day name in week (Tuesday; Tue)u
- Day number of week (1 = Monday, ..., 7 = Sunday)a
- AM/PM markerH
- Hour in day (0-23)k
- Hour in day (1-24)K
- Hour in am/pm (0-11)h
- Hour in am/pm (1-12)m
- Minute in hour (30)s
- Second in minute (55)S
- Millisecond (978)z
- General time zone (Pacific Standard Time; PST; GMT-08:00)Z
- RFC 822 time zone (-0800)X
- ISO 8601 time zone (-08; -0800; -08:00)To parse:
2000-01-23T04:56:07.000+0000
Use:
new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
As Marc says, you run it exactly like you would from the command line. See Creating SQL Server Agent Jobs on MSDN.
JAR File Manifest Attributes for Security
The JAR file manifest contains information about the contents of the JAR file, including security and configuration information.
Add the attributes to the manifest before the JAR file is signed.
See Modifying a Manifest File in the Java Tutorial for information on adding attributes to the JAR manifest file.
Permissions Attribute
The Permissions attribute is used to verify that the permissions level requested by the RIA when it runs matches the permissions level that was set when the JAR file was created.
Use this attribute to help prevent someone from re-deploying an application that is signed with your certificate and running it at a different privilege level. Set this attribute to one of the following values:
sandbox - runs in the security sandbox and does not require additional permissions.
all-permissions - requires access to the user's system resources.
Changes to Security Slider:
The following changes to Security Slider were included in this release(7u51):

I had the same error caused by build errors. I ran ng build in the directory of my application which helped me correct my errors
Try HostingEnvironment.MapPath
, which is static
.
See this SO question for confirmation that HostingEnvironment.MapPath
returns the same value as Server.MapPath
: What is the difference between Server.MapPath and HostingEnvironment.MapPath?
a reduce helper can do the trick (without type checking) -
const cleanObj = Object.entries(objToClean).reduce((acc, [key, value]) => {
if (value) {
acc[key] = value;
}
return acc;
}, {});
Start the project structure( file>structure
)
You can see:
on the left, modules list;
on the right, Properties>Build
Tools Version
there maybe are more than one modules.
change "Build Tools Version"
for every Module.
it works.
If you can edit all documents in aggregate :
"TimeStamp": {$toDecimal: {$toDate: "$Your Date"}}
And for the client, you set the query :
Date.parse("Your date".toISOString())
That's what makes you whole work with ISODate.
I had a similar problem with 'org.codehaus.mojo'-'jaxws-maven-plugin': could not resolve dependencies. Fortunately, I was able to do a Project > Clean in Eclipse, which resolved the issue.
None of those answers include a counter...
#!/bin/bash
## declare an array variable
declare -a array=("one" "two" "three")
# get length of an array
arraylength=${#array[@]}
# use for loop to read all values and indexes
for (( i=1; i<${arraylength}+1; i++ ));
do
echo $i " / " ${arraylength} " : " ${array[$i-1]}
done
Output:
1 / 3 : one
2 / 3 : two
3 / 3 : three
As an improvement on Peters code above you can use this:
var roleManager = new RoleManager<Microsoft.AspNet.Identity.EntityFramework.IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));
if (!roleManager.RoleExists("Member"))
roleManager.Create(new IdentityRole("Member"));
This is what I came up with:
$(document).ready(function(){_x000D_
_x000D_
$(".fc-event").each(function(){_x000D_
_x000D_
console.log(this.attributes['data'].nodeValue) _x000D_
});_x000D_
_x000D_
});
_x000D_

I think that both are functionally the same, but they simply have different authors, and the one is simply named more appropriately than the other.
Here is a quick backgrounder in naming conventions (for those unfamiliar), which explains the frustration by the question asker: For many *nix applications, the piece that does the backend work is called a "daemon" (think "service" in Windows-land), while the interface or client application is what you use to control or access the daemon. The daemon is most often named the same as the client, with the letter "d" appended to it. For example "imap" would be a client that connects to the "imapd" daemon.
This naming convention is clearly being adhered to by memcache when you read the introduction to the memcache module (notice the distinction between memcache and memcached in this excerpt):
Memcache module provides handy procedural and object oriented interface to memcached, highly effective caching daemon, which was especially designed to decrease database load in dynamic web applications.
The Memcache module also provides a session handler (memcache).
More information about memcached can be found at » http://www.danga.com/memcached/.
The frustration here is caused by the author of the PHP extension which was badly named memcached, since it shares the same name as the actual daemon called memcached. Notice also that in the introduction to memcached (the php module), it makes mention of libmemcached, which is the shared library (or API) that is used by the module to access the memcached daemon:
memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.
This extension uses libmemcached library to provide API for communicating with memcached servers. It also provides a session handler (memcached).
Information about libmemcached can be found at » http://tangent.org/552/libmemcached.html.
file 1:
int x = 50;
file 2:
extern int x;
printf("%d", x);
points_small = dict(filter(lambda (a,(b,c)): b<5 and c < 5, points.items()))
You can add a hidden
input
with whatever value you need to send:
$('#form').submit(function(eventObj) {
$(this).append('<input type="hidden" name="someName" value="someValue">');
return true;
});
I did notice something of interest here: In my 2.3.4 phone I can't see AP/AdHoc SSIDs in the Settings > Wireless & Networks menu. On an Acer A500 running 4.0.3 I do see them, prefixed by (*)
However in the following bit of code that I adapted from (can't remember source, sorry!) I do see the Ad Hoc show up in the Wifi Scan on my 2.3.4 phone. I am still looking to actually connect and create a socket + input/outputStream. But, here ya go:
public class MainActivity extends Activity {
private static final String CHIPKIT_BSSID = "E2:14:9F:18:40:1C";
private static final int CHIPKIT_WIFI_PRIORITY = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button btnDoSomething = (Button) findViewById(R.id.btnDoSomething);
final Button btnNewScan = (Button) findViewById(R.id.btnNewScan);
final TextView textWifiManager = (TextView) findViewById(R.id.WifiManager);
final TextView textWifiInfo = (TextView) findViewById(R.id.WifiInfo);
final TextView textIp = (TextView) findViewById(R.id.Ip);
final WifiManager myWifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
final WifiInfo myWifiInfo = myWifiManager.getConnectionInfo();
WifiConfiguration wifiConfiguration = new WifiConfiguration();
wifiConfiguration.BSSID = CHIPKIT_BSSID;
wifiConfiguration.priority = CHIPKIT_WIFI_PRIORITY;
wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
wifiConfiguration.allowedKeyManagement.set(KeyMgmt.NONE);
wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
wifiConfiguration.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
wifiConfiguration.status = WifiConfiguration.Status.ENABLED;
myWifiManager.setWifiEnabled(true);
int netID = myWifiManager.addNetwork(wifiConfiguration);
myWifiManager.enableNetwork(netID, true);
textWifiInfo.setText("SSID: " + myWifiInfo.getSSID() + '\n'
+ myWifiManager.getWifiState() + "\n\n");
btnDoSomething.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
clearTextViews(textWifiManager, textIp);
}
});
btnNewScan.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
getNewScan(myWifiManager, textWifiManager, textIp);
}
});
}
private void clearTextViews(TextView...tv) {
for(int i = 0; i<tv.length; i++){
tv[i].setText("");
}
}
public void getNewScan(WifiManager wm, TextView...textViews) {
wm.startScan();
List<ScanResult> scanResult = wm.getScanResults();
String scan = "";
for (int i = 0; i < scanResult.size(); i++) {
scan += (scanResult.get(i).toString() + "\n\n");
}
textViews[0].setText(scan);
textViews[1].setText(wm.toString());
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
Don't forget that in Eclipse you can use Ctrl+Shift+[letter O] to fill in the missing imports...
and my manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.digilent.simpleclient"
android:versionCode="1"
android:versionName="1.0" >

1) It looks possible. This info on Github describes how to create a java program to send a message using the whatsapp encryption protocol from WhisperSystems.
2) No. See the whatsapp security white paper.

There's a very simple hack that fixes this issue
Here's a codesandbox that illustrates the solution: https://codesandbox.io/s/00w06z1n5l
HTML
<div id="parent">
<div class="hack">
<div class="child">

</div>
</div>
CSS
.parent { position: relative; width: 100%; }
.hack { position: absolute; left:0; right:0; top:0;}
.child { position: absolute; left: 0; right: 0; bottom:0; }
you can play with the positioning of the hack div to affect where the child positions itself.

The image should be embedded in the message as an attachment like this:
--boundary
Content-Type: image/png; name="sig.png"
Content-Disposition: inline; filename="sig.png"
Content-Transfer-Encoding: base64
Content-ID: <0123456789>
Content-Location: sig.png
base64 data
--boundary
And, the HTML part would reference the image like this:
<img src="cid:0123456789">
In some clients, src="sig.png" will work too.
You'd basically have a multipart/mixed, multipart/alternative, multipart/related message where the image attachment is in the related part.
Clients shouldn't block this image either as it isn't remote.
Or, here's a multipart/alternative, multipart/related example as an mbox file (save as windows newline format and put a blank line at the end. And, use no extension or the .mbs extension):

You can import that into Sylpheed or Thunderbird (with the Import/Export tools extension) or Opera's built-in mail client. Then, in Opera for example, you can toggle "prefer plain text" to see the difference between the HTML and text version. Anyway, you'll see the HTML version makes use of the embedded pic in the sig.
tl;dr: No! Arrow functions and function declarations / expressions are not equivalent and cannot be replaced blindly.
If the function you want to replace does not use this
, arguments
and is not called with new
, then yes.
As so often: it depends. Arrow functions have different behavior than function declarations / expressions, so let's have a look at the differences first:
1. Lexical this
and arguments
Arrow functions don't have their own this
or arguments
binding. Instead, those identifiers are resolved in the lexical scope like any other variable. That means that inside an arrow function, this
and arguments
refer to the values of this
and arguments
in the environment the arrow function is defined in (i.e. "outside" the arrow function):
// Example using a function expression
function createObject() {
console.log('Inside `createObject`:', this.foo);
return {
foo: 42,
bar: function() {
console.log('Inside `bar`:', this.foo);
},
};
}
createObject.call({foo: 21}).bar(); // override `this` inside createObject
_x000D_
// Example using a arrow function
function createObject() {
console.log('Inside `createObject`:', this.foo);
return {
foo: 42,
bar: () => console.log('Inside `bar`:', this.foo),
};
}
createObject.call({foo: 21}).bar(); // override `this` inside createObject
_x000D_
In the function expression case, this
refers to the object that was created inside the createObject
. In the arrow function case, this
refers to this
of createObject
itself.
This makes arrow functions useful if you need to access the this
of the current environment:
// currently common pattern
var that = this;
getData(function(data) {
that.data = data;
});
// better alternative with arrow functions
getData(data => {
this.data = data;
});
Note that this also means that is not possible to set an arrow function's this
with .bind
or .call
.
If you are not very familiar with this
, consider reading
2. Arrow functions cannot be called with new
ES2015 distinguishes between functions that are callable and functions that are constructable. If a function is constructable, it can be called with new
, i.e. new User()
. If a function is callable, it can be called without new
(i.e. normal function call).
Functions created through function declarations / expressions are both constructable and callable.
Arrow functions (and methods) are only callable.
class
constructors are only constructable.
If you are trying to call a non-callable function or to construct a non-constructable function, you will get a runtime error.
Knowing this, we can state the following.
Replaceable:
this
or arguments
..bind(this)
Not replaceable:
this
)arguments
(see below))Lets have a closer look at this using your examples:
Constructor function
This won't work because arrow functions cannot be called with new
. Keep using a function declaration / expression or use class
.
Prototype methods
Most likely not, because prototype methods usually use this
to access the instance. If they don't use this
, then you can replace it. However, if you primarily care for concise syntax, use class
with its concise method syntax:
class User {
constructor(name) {
this.name = name;
}
getName() {
return this.name;
}
}
Object methods
Similarly for methods in an object literal. If the method wants to reference the object itself via this
, keep using function expressions, or use the new method syntax:
const obj = {
getName() {
// ...
},
};
Callbacks
It depends. You should definitely replace it if you are aliasing the outer this
or are using .bind(this)
:
// old
setTimeout(function() {
// ...
}.bind(this), 500);
// new
setTimeout(() => {
// ...
}, 500);
But: If the code which calls the callback explicitly sets this
to a specific value, as is often the case with event handlers, especially with jQuery, and the callback uses this
(or arguments
), you cannot use an arrow function!
Variadic functions
Since arrow functions don't have their own arguments
, you cannot simply replace them with an arrow function. However, ES2015 introduces an alternative to using arguments
: the rest parameter.
// old
function sum() {
let args = [].slice.call(arguments);
// ...
}
// new
const sum = (...args) => {
// ...
};

You'll get converting errors with:
cmd.CommandText = "SELECT COUNT(*) FROM table_name";
Int32 count = (Int32) cmd.ExecuteScalar();
Use instead:
string stm = "SELECT COUNT(*) FROM table_name WHERE id="+id+";";
MySqlCommand cmd = new MySqlCommand(stm, conn);
Int32 count = Convert.ToInt32(cmd.ExecuteScalar());
if(count > 0){
found = true;
} else {
found = false;
}
See if your needs are met by a DialogFragment. DialogFragment has a dismiss() method. Much cleaner in my opinion.
If you're already using jquery, I don't see why you wouldn't also be able to use a lightweight overlay plugin. Other people have already written some nice ones in jquery, so why re-invent the wheel?
In case the OP really wanted an ICMP-Ping, there are some proposals within the User Contributed Notes to socket_create()
[link], which use raw sockets. Be aware that on UNIX like systems root access is required.
Update: note that the usec
argument has no function on windows. Minimum timeout is 1 second.
In any case, this is the code of the top voted ping function:
function ping($host, $timeout = 1) {
/* ICMP ping packet with a pre-calculated checksum */
$package = "\x08\x00\x7d\x4b\x00\x00\x00\x00PingHost";
$socket = socket_create(AF_INET, SOCK_RAW, 1);
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, array('sec' => $timeout, 'usec' => 0));
socket_connect($socket, $host, null);
$ts = microtime(true);
socket_send($socket, $package, strLen($package), 0);
if (socket_read($socket, 255)) {
$result = microtime(true) - $ts;
} else {
$result = false;
}
socket_close($socket);
return $result;
}

From a user experience stand-point, you don't want a major action to be done passively.
Something major like a window close should be the result of an action by the user.
For all of you who believe the myth that temp variables are in memory only
First, the table variable is NOT necessarily memory resident. Under memory pressure, the pages belonging to a table variable can be pushed out to tempdb.

If we consider a JavaScript integer to be a value of maximum 4294967295
(i.e. Math.pow(2,32)-1
), then the following short solution will perfectly work:
function isPositiveInteger(n) {
return n >>> 0 === parseFloat(n);
}
DESCRIPTION:
123.45 >>> 0 === 123
-1 >>> 0 === 4294967295

1e10 >>> 0 === 1410065408
1e7 >>> 0 === 10000000

Another way is good for all numeric values which are valid up to Number.MAX_VALUE
, i.e. to about 1.7976931348623157e+308
:
function isPositiveInteger(n) {
return 0 === n % (!isNaN(parseFloat(n)) && 0 <= ~~n);
}
DESCRIPTION:
!isNaN(parseFloat(n))
is used to filter pure string values, e.g. ""
, " "
, "string"
;0 <= ~~n
filters negative and large non-integer values, e.g. "-40.1"
, "129000098131766699"
;(!isNaN(parseFloat(n)) && 0 <= ~~n)
returns true
if value is both numeric and positive;0 === n % (...)
checks if value is non-float -- here (...)
(see 3) is evaluated as 0
in case of false
, and as 1
in case of true
.TESTS:
"0" : true
"23" : true
"-10" : false
"10.30" : false
"-40.1" : false

The previous version:
function isPositiveInteger(n) {
return n == "0" || ((n | 0) > 0 && n % 1 == 0);
}
REPEAT

UNTIL cond
Is equivalent to
while True:

To make @Raghavendra's answer more specific:
Once you've downloaded 2 zip files,
copy ALL the contents of "win64_11gR2_database_2of2.zip -> Database -> Stage -> Components" folder to "win64_11gR2_database_1of2.zip -> Database -> Stage -> Components" folder.
You'll still get the same warning, however, the installation will run completely without generating any errors.
If you want to present the values in a map in sorted order, then copy the values from the map to vector and sort the vector.
Just pick up the TDM-GCC 64x package. (It constains both the 32 and 64 bit versions of the MinGW toolchain and comes within a neat installer.) More importantly, it contains something called the "winpthread" library.
It comprises of the pthread.h
header, libwinpthread.a
, libwinpthread.dll.a
static libraries for both 32-bit and 64-bit and the required .dlls libwinpthread-1.dll
and libwinpthread_64-1.dll
(this, as of 01-06-2016).
You'll need to link to the libwinpthread.a
library during build. Other than that, your code can be the same as for native Pthread code on Linux. I've so far successfully used it to compile a few basic Pthread programs in 64-bit on windows.
Alternatively, you can use the following library which wraps the windows threading API into the pthreads API: pthreads-win32.
The above two seem to be the most well known ways for this.
Hope this helps.
I am not clear exactly what your situation requires but the following may get you started. The key here is using ThisWorkbook.Path
to get a relative file path:
Sub SaveToRelativePath()
Dim relativePath As String
relativePath = ThisWorkbook.Path & Application.PathSeparator & ActiveWorkbook.Name
ActiveWorkbook.SaveAs Filename:=relativePath
End Sub
Ondrasej is the "most right" here, IMO.
There are also gui-er ways to do it, without resorting to Xcode. I like TryC.
Mac OS X includes Developer Tools, a developing environment for making Macintosh applications. However, if someone wants to study programming using C, Xcode is too big and too complicated for beginners, to write a small sample program. TryC is very suitable for beginners.
You don't need to launch a huge Xcode application, or type unfamiliar commands in Terminal. Using TryC, you can write, compile and run a C, C++ and Ruby program just like TextEdit. It's only available to compile one source code file but it's enough for trying sample programs.
The Cdata is a data which you may want to pass to an xml parser and still not interpreted as an xml.
Say for eg :- You have an xml which has encapsulates question/answer object . Such open fields can have any data which does not strictly fall under basic data type or xml defined custom data types. Like --Is this a correct tag for xml comment ? .-- You may have a requirement to pass it as it is without being interpreted by the xml parser as another child element. Here Cdata comes to your rescue . By declaring as Cdata you are telling the parser don't treat the data wrapped as an xml (though it may look like one )

If you are using windows, you should make sure that the certificate file csr.pem and key.pem don't have unix-style line endings. Openssl will generate the key files with unix style line endings. You can convert these files to dos format using a utility like unix2dos or a text editor like notepad++
I was facing very similar problem while trying to insert data using mysql-connector-net-5.1.7-noinstall and Visual Studio(2015) in Windows Form Application. I am not a C# guru. So, it takes around 2 hours to resolve everything.
The following code works lately:
string connetionString = null;
connetionString = "server=localhost;database=device_db;uid=root;pwd=123;";
using (MySqlConnection cn = new MySqlConnection(connetionString))
{
try
{
string query = "INSERT INTO test_table(user_id, user_name) VALUES (?user_id,?user_name);";
cn.Open();
using (MySqlCommand cmd = new MySqlCommand(query, cn))
{
cmd.Parameters.Add("?user_id", MySqlDbType.Int32).Value = 123;
cmd.Parameters.Add("?user_name", MySqlDbType.VarChar).Value = "Test username";
cmd.ExecuteNonQuery();
}
}
catch (MySqlException ex)
{
MessageBox.Show("Error in adding mysql row. Error: "+ex.Message);
}
}
Strings are not really immutable. They are just publicly immutable. It means you cannot modify them from their public interface. But in the inside the are actually mutable.
If you don't believe me look at the String.Concat
definition using reflector.
The last lines are...
int length = str0.Length;
string dest = FastAllocateString(length + str1.Length);
FillStringChecked(dest, 0, str0);
FillStringChecked(dest, length, str1);
return dest;
As you can see the FastAllocateString
returns an empty but allocated string and then it is modified by FillStringChecked
Actually the FastAllocateString
is an extern method and the FillStringChecked
is unsafe so it uses pointers to copy the bytes.
Maybe there are better examples but this is the one I have found so far.
In order to keep a POD running it should to be performing certain task, otherwise Kubernetes will find it unnecessary, therefore it stops. There are many ways to keep a POD running.
I have faced similar problems when I needed a POD just to run continuously without doing any useful operation. The following are the two ways those worked for me:
Although the first option is easier than the second one and may suffice the requirement, it is not the best option. As, there is a limit as far as the number of seconds you are going to assign in the sleep command. But a container with infinite loop running inside it never exits.
However, I will describe both the ways(Considering you are running busybox container):
1. Sleep Command
apiVersion: v1
kind: Pod
metadata:
name: busybox
labels:
app: busybox
spec:
containers:
- name: busybox
image: busybox
ports:
- containerPort: 80
command: ["/bin/sh", "-ec", "sleep 1000"]
nodeSelector:
beta.kubernetes.io/os: linux
2. Infinite Loop
apiVersion: v1
kind: Pod
metadata:
name: busybox
labels:
app: busybox
spec:
containers:
- name: busybox
image: busybox
ports:
- containerPort: 80
command: ["/bin/sh", "-ec", "while :; do echo '.'; sleep 5 ; done"]
nodeSelector:
beta.kubernetes.io/os: linux
Run the following command to run the pod:
kubectl apply -f <pod-yaml-file-name>.yaml
Hope it helps!
Adding the following two lines in the script solved the issue for me.
# !/usr/bin/python
# coding=utf-8
Hope it helps !
You must use the Invoke-Command cmdlet to launch this external program. Normally it works without an effort.
If you need more than one command you should use the Invoke-Expression cmdlet with the -scriptblock
option.
I'm not quite sure what a "good way" of copying a file is, but assuming "good" means "fast", I could broaden the subject a little.
Current operating systems have long been optimized to deal with run of the mill file copy. No clever bit of code will beat that. It is possible that some variant of your copy techniques will prove faster in some test scenario, but they most likely would fare worse in other cases.
Typically, the sendfile
function probably returns before the write has been committed, thus giving the impression of being faster than the rest. I haven't read the code, but it is most certainly because it allocates its own dedicated buffer, trading memory for time. And the reason why it won't work for files bigger than 2Gb.
As long as you're dealing with a small number of files, everything occurs inside various buffers (the C++ runtime's first if you use iostream
, the OS internal ones, apparently a file-sized extra buffer in the case of sendfile
). Actual storage media is only accessed once enough data has been moved around to be worth the trouble of spinning a hard disk.
I suppose you could slightly improve performances in specific cases. Off the top of my head:
copy_file
sequentially (though you'll hardly notice the difference as long as the file fits in the OS cache)But all that is outside the scope of a general purpose file copy function.
So in my arguably seasoned programmer's opinion, a C++ file copy should just use the C++17 file_copy
dedicated function, unless more is known about the context where the file copy occurs and some clever strategies can be devised to outsmart the OS.
This will make the div fixed at the bottom of the page but in case the page is long it will only be visible when you scroll down.

The height and margin-top should be the same so that the footer doesnt show over the content.

After update, such as
ALTER TABLE table_name modify column_name tinyint(4) NOT NULL;
If you get

MySQL will assume the part before the equals references the columns named in the INSERT INTO clause, and the second part references the SELECT columns.

I'm sure you have your reasons, but just in case... you should also consider using a "merge" query instead:
begin
merge into some_table st
using (select 'some' name, 'values' value from dual) v
on (st.name=v.name)
when matched then update set st.value=v.value
when not matched then insert (name, value) values (v.name, v.value);
end;
(modified the above to be in the begin/end block; obviously you can run it independantly of the procedure too).
In order to avoid such error you could use CASE
+ ISNUMERIC
to handle scenarios when you cannot convert to int.
Change
CONVERT(INT, CONVERT(VARCHAR(12), a.value))
To
CONVERT(INT,
CASE
WHEN IsNumeric(CONVERT(VARCHAR(12), a.value)) = 1 THEN CONVERT(VARCHAR(12),a.value)
ELSE 0 END)
Basically this is saying if you cannot convert me to int assign value of 0 (in my example)
Alternatively you can look at this article about creating a custom function that will check if a.value
is number: http://www.tek-tips.com/faqs.cfm?fid=6423
For the actual processing I'd keep a string of finished product, and loop through each letter in the string they have entered. I'd call a function to convert a letter to morse code, then add it to the string of existing morse code.
finishedProduct = []
userInput = input("Enter text")
for letter in userInput:
finishedProduct.append( letterToMorseCode(letter) )
theString = ''.join(finishedProduct)
print(theString)
You could either check for space in the loop, or in the function that is called.
It's not firing because the value hasn't "changed". It's the same value. Unfortunately, you can't achieve the desired behaviour using the change
event.
You can handle the blur
event and do whatever processing you need when the user leaves the select box. That way you can run the code you need even if the user selects the same value.
Use .onkeydown
and cancel the removing with return false;
. Like this:
var input = document.getElementById('myInput');
input.onkeydown = function() {
var key = event.keyCode || event.charCode;
if( key == 8 || key == 46 )
return false;
};
Or with jQuery, because you added a jQuery tag to your question:
jQuery(function($) {
var input = $('#myInput');
input.on('keydown', function() {
var key = event.keyCode || event.charCode;
if( key == 8 || key == 46 )
return false;
});
});
?
!= is OK to compare two variables. It doesn't work, though, with multiple comparisons.
Time complexity is O(E+V)
instead of O(2E+V)
because if the time complexity is n^2+2n+7 then it is written as O(n^2).
Hence, O(2E+V) is written as O(E+V)
because difference between n^2 and n matters but not between n and 2n.
In my case I had a href with a # and target.href was returning me the complete url. Target.hash did the work for me.
$(".test a").on('click', function(e) {
console.log(e.target.href); // logs https://www.test.com/#test
console.log(e.target.hash); // logs #test
});
A normal math answer.
Understanding that a floating point number is implemented as some bits representing the exponent and the rest, most for the digits (in the binary system), one has the following situation:
With a high exponent, say 10²³ if the least significant bit is changed, a large difference between two adjacent distinghuishable numbers appear. Furthermore the base 2 decimal point makes that many base 10 numbers can only be approximated; 1/5, 1/10 being endless numbers.
So in general: floating point numbers should not be used if you care about significant digits. For monetary amounts with calculation, e,a, best use BigDecimal.
For physics floating point doubles are adequate, floats almost never. Furthermore the floating point part of processors, the FPU, can even use a bit more precission internally.

Actually you can pass a parameter ( http://docs.angularjs.org/api/ng.filter:filter ) and don't need a custom function just for this. If you rewrite your HTML as below it'll work:

I know the OP was very old, at that time in-app-update was not available. But from API 21, you can use in-app-update checking. You may need to keep your eyes on some points which are nicely written up here:
ActionResult is an abstract class that can have several subtypes.
ViewResult - Renders a specifed view to the response stream
PartialViewResult - Renders a specifed partial view to the response stream
EmptyResult - An empty response is returned
RedirectResult - Performs an HTTP redirection to a specifed URL
RedirectToRouteResult - Performs an HTTP redirection to a URL that is determined by the routing engine, based on given route data
JsonResult - Serializes a given ViewData object to JSON format
JavaScriptResult - Returns a piece of JavaScript code that can be executed on the client
ContentResult - Writes content to the response stream without requiring a view
FileContentResult - Returns a file to the client
FileStreamResult - Returns a file to the client, which is provided by a Stream
FilePathResult - Returns a file to the client

Here's how to make your very own cls
or clear
command that will work without explicitly calling any function!
We'll take advantage of the fact that the python console calls repr()
to display objects on screen. This is especially useful if you have your own customized python shell (with the -i
option for example) and you have a pre-loading script for it. This is what you need:
import os
class ScreenCleaner:
def __repr__(self):
os.system('cls') # This actually clears the screen
return '' # Because that's what repr() likes
cls = ScreenCleaner()
Use clear
instead of cls
if you're on linux (in both the os
command and the variable name)!
Now if you just write cls
or clear
in the console - it will clear it! Not even cls()
or clear()
- just the raw variable. This is because python will call repr(cls)
to print it out, which will in turn trigger our __repr__
function.
Let's test it out:
>>> df;sag
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'df' is not defined
>>> sglknas
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'sglknas' is not defined
>>> lksnldn
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'lksnldn' is not defined
>>> cls
And the screen is clear!
To clarify - the code above needs to either be imported in the console like this
from somefile import cls
Or pre load directly with something like:
python -i my_pre_loaded_classes.py
<div (window:resize)="onResize($event)"
onResize(event) {
event.target.innerWidth;
}
or using the HostListener decorator:
@HostListener('window:resize', ['$event'])
onResize(event) {
event.target.innerWidth;
}
Supported global targets are window
, document
, and body
.
Until https://github.com/angular/angular/issues/13248 is implemented in Angular it is better for performance to subscribe to DOM events imperatively and use RXJS to reduce the amount of events as shown in some of the other answers.
You can use mydict['Apple'].keys()[0]
in order to get the first key in the Apple
dictionary, but there's no guarantee that it will be American
. The order of keys in a dictionary can change depending on the contents of the dictionary and the order the keys were added.
First, you should install "platformio-ide-terminal": Open "Preferences ?," >> Click "+ Install" >> In "Search packages" type "platformio-ide-terminal" >> Click "Install".
And answering exactly the question. If you have previously installed, just use:
ctrl-`
or Option+Command+T (??T)It's also important to realize that simply moving the program break pointer around with brk
and sbrk
doesn't actually allocate the memory, it just sets up the address space. On Linux, for example, the memory will be "backed" by actual physical pages when that address range is accessed, which will result in a page fault, and will eventually lead to the kernel calling into the page allocator to get a backing page.

This problem is not new to Visual Studio:
Remove Git binding from Visual Studio 2013 solution?
This all seems like a lot of work for something that should probably be a built-in feature. The above "solutions" mention making modifications to the .git file etc.; I don't like the idea of having to change things outside of Visual Studio to affect things inside Visual Studio. Although my solution needs to make a few registry edits (and is external to VS), at least these only affect VS. Here is the work-around (read: hack):
Be sure to have Visual Studio 2015 closed before following these steps.
1. Open regedit.exe and navigate to
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0\TeamFoundation\GitSourceControl\Repositories
You might see multiple "hash" values that represent the repositories that VS is tracking.
2. Find the git repository you want to remove from the list. Look at the name
and path
values to verify the correct repository to delete:
3. Delete the key (and corresponding subkeys).
(Optional: before deleting, you can right click and choose Export to back up this key in case you make a mistake.) Now, right click on the key (in my case this is AE76C67B6CD2C04395248BFF8EBF96C7AFA15AA9
and select Delete).
4. Check that the LastUsedRepository
key points to "something else."
If the repository mapping you are trying to remove in the above steps is stored in LastUsedRepository
, then you'll need to remove this key, also. First navigate to:
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0\TeamFoundation\GitSourceControl\General
and delete the key LastUsedRepository
(the key will be re-created by VS if needed). If you are worried about removing the key, you can just modify the value and set it to an empty string:
When you open Visual Studio 2015 again, the git repository binding should not appear in the list anymore.
If you want to include a time frame in the future, with the current year (e.g. 2017) as the start year so that next year it’ll appear like this: “© 2017-2018, Company.”, then use the following code. It’ll automatically update each year:
© Copyright 2017<script>new Date().getFullYear()>2017&&document.write("-"+new Date().getFullYear());</script>, Company.
© Copyright 2017-2018, Company.
But if the first year has already passed, the shortest code can be written like this:
© Copyright 2010-<script>document.write(new Date().getFullYear())</script>, Company.
Sorry Guys. I have solved this Issue long ago. I did a lot of changes. So I can't figure out which one does the trick.
I have changed the id as suggested by Jared Burrows.
Removed my support library and cleaned my project and Re added it.
Go to File -> Invalidate Caches/Restart.
Hope it works.
This is how my code looks now

Failing custom jackson Serializers/Deserializers could also be the problem. Though it's not your case, it's worth mentioning.
I faced the same exception and that was the case.
It is a little complicated, but you can draw all the objects by the following code:
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
from itertools import product, combinations
fig = plt.figure()
ax = fig.gca(projection='3d')
ax.set_aspect("equal")
# draw cube
r = [-1, 1]
for s, e in combinations(np.array(list(product(r, r, r))), 2):
if np.sum(np.abs(s-e)) == r[1]-r[0]:
ax.plot3D(*zip(s, e), color="b")
# draw sphere
u, v = np.mgrid[0:2*np.pi:20j, 0:np.pi:10j]
x = np.cos(u)*np.sin(v)
y = np.sin(u)*np.sin(v)
z = np.cos(v)
ax.plot_wireframe(x, y, z, color="r")
# draw a point
ax.scatter([0], [0], [0], color="g", s=100)
# draw a vector
from matplotlib.patches import FancyArrowPatch
from mpl_toolkits.mplot3d import proj3d
class Arrow3D(FancyArrowPatch):
def __init__(self, xs, ys, zs, *args, **kwargs):
FancyArrowPatch.__init__(self, (0, 0), (0, 0), *args, **kwargs)
self._verts3d = xs, ys, zs
def draw(self, renderer):
xs3d, ys3d, zs3d = self._verts3d
xs, ys, zs = proj3d.proj_transform(xs3d, ys3d, zs3d, renderer.M)
self.set_positions((xs[0], ys[0]), (xs[1], ys[1]))
FancyArrowPatch.draw(self, renderer)
a = Arrow3D([0, 1], [0, 1], [0, 1], mutation_scale=20,
lw=1, arrowstyle="-|>", color="k")
ax.add_artist(a)
plt.show()
Use a div for your divider. It will always be centered vertically regardless to whether left and right divs are equal in height. You can reuse it anywhere on your site.
.divider{
position:absolute;
left:50%;
top:10%;
bottom:10%;
border-left:1px solid white;
}
Use the "has attribute" selector:
$('p[MyTag]')
Or to select one where that attribute has a specific value:
$('p[MyTag="Sara"]')
There are other selectors for "attribute value starts with", "attribute value contains", etc.
Some notes that I also found useful:
Keep your default values on the right side.
function whatever($var1, $var2, $var3="constant", $var4="another")
The default value of the argument must be a constant expression. It can't be a variable or a function call.
A simpler way is
ggplot(data=df, aes(x=xvar, y=yvar)) +
geom_point()
ggsave(path = path, width = width, height = height, device='tiff', dpi=700)
You possibly do not have create permissions to the folder. So WinSCP fails to create a temporary file for the transfer.
You have two options:
Grant write permissions to the folder to the user or group you log in with (myuser
), or change the ownership of the folder to the user, or
Disable a transfer to temporary file.
In Preferences, go to Transfer > Endurance page and in Enable transfer resume/transfer to temporary file name for select Disable:
simple you can write:
<?= $form->field($model, 'hidden1')->hiddenInput(['value'=>'abc value'])->label(false); ?>
Answering this old question is pretty pointless, but there is a simple answer that speaks to the nature of Javascript. Objects in Javascript are inherently hash tables. We can use this to get a hash of unique keys:
var o = {}; array.map(function(v){ o[v.age] = 1; });
Then we can reduce the hash to an array of unique values:
var a2 = []; for (k in o){ a2.push(k); }
That is all you need. The array a2 contains just the unique ages.
In response to: "How to convert Tue Sep 13 2016 00:00:00 GMT-0500 (Hora de verano central (México)) to dd-MM-yy in Java?", it was marked how duplicate
Try this:
With java.util.Date
, java.text.SimpleDateFormat
, it's a simple solution.
public static void main(String[] args) throws ParseException {
String fecha = "Tue Sep 13 2016 00:00:00 GMT-0500 (Hora de verano central (México))";
Date f = new Date(fecha);
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
sdf.setTimeZone(TimeZone.getTimeZone("-5GMT"));
fecha = sdf.format(f);
System.out.println(fecha);
}
ng generate component componentName.
It will automatically import the component in module.ts
If you use angular-cli you can do :
Install the dependency :
npm install jquery --save
npm install @types/jquery --save-dev
Import the file :
Add "../node_modules/jquery/dist/jquery.min.js" to the "script" section in .angular-cli.json file
Declare jquery :
Add "$" to the "types" section of tsconfig.app.json
You can find more details on official angular cli doc
You can call ViewController this way, If you want with NavigationController

There is this function scandir():
$dir = 'dir';
$files = scandir($dir, 0);
for($i = 2; $i < count($files); $i++)
print $files[$i]."<br>";
I included the name of the new App to the INSTALLED_APPS list in the settings.py "before" I issued the startapp command. Once I removed the list entry, I could create the app.
This because a char
is stored at all effects as a 8-bit number. Speaking about a negative or positive char
doesn't make sense if you consider it an ASCII code (which can be just signed*) but makes sense if you use that char
to store a number, which could be in range 0-255 or in -128..127 according to the 2-complement representation.
*: it can be also unsigned, it actually depends on the implementation I think, in that case you will have access to extended ASCII charset provided by the encoding used
This answer is a supplement to Sebastian Rittau's answer responding to the comment: "but what if you don't have the module name?" This is a quick and dirty way of getting the likely python module name given a filename -- it just goes up the tree until it finds a directory without an __init__.py
file and then turns it back into a filename. For Python 3.4+ (uses pathlib), which makes sense since Py2 people can use "imp" or other ways of doing relative imports:
import pathlib
def likely_python_module(filename):
'''
Given a filename or Path, return the "likely" python module name. That is, iterate
the parent directories until it doesn't contain an __init__.py file.
:rtype: str
'''
p = pathlib.Path(filename).resolve()
paths = []
if p.name != '__init__.py':
paths.append(p.stem)
while True:
p = p.parent
if not p:
break
if not p.is_dir():
break
inits = [f for f in p.iterdir() if f.name == '__init__.py']
if not inits:
break
paths.append(p.stem)
return '.'.join(reversed(paths))
There are certainly possibilities for improvement, and the optional __init__.py
files might necessitate other changes, but if you have __init__.py
in general, this does the trick.
Your problem is here:
2013-11-14 17:57:20 5180 [ERROR] InnoDB: .\ibdata1 can't be opened in read-write mode
There's some problem with the ibdata1 file - maybe the permissions have changed on it? Perhaps some other process has it open. Does it even exist?
Fix this and possibly everything else will fall into place.
You can do it by making form and displaying it using ShowDialogBox....
Form.ShowDialog Method
- Shows the form as a modal dialog box.
Example:
public void ShowMyDialogBox()
{
Form2 testDialog = new Form2();
// Show testDialog as a modal dialog and determine if DialogResult = OK.
if (testDialog.ShowDialog(this) == DialogResult.OK)
{
// Read the contents of testDialog's TextBox.
this.txtResult.Text = testDialog.TextBox1.Text;
}
else
{
this.txtResult.Text = "Cancelled";
}
testDialog.Dispose();
}
Check out SQL For Smarties. I thought I was pretty good with SQL too, until I read that book... Goes into tons of depth, talks about things I've not seen elsewhere (I.E. difference between 3'rd and 4'th normal form, Boyce Codd Normal Form, etc)...
you can check like this
declare @vchar varchar(50)
set @vchar ='34343';
select case when @vchar not like '%[^0-9]%' then 'Number' else 'Not a Number' end
If you deal with .xlsm
file instead of .xls
you can use the old method. I was trying to modify vbaProject.bin
in .xlsm
several times using DBP->DBx
method by it didn't work, also changing value of DBP
didn't. So I was very suprised that following worked :
1. Save .xlsm
as .xls
.
2. Use DBP->DBx
method on .xls
.
3. Unfortunately some erros may occur when using modified .xls
file, I had to save .xls
as .xlsx
and add modules, then save as .xlsm
.
Putting the expressions in a list may simulate multiple expressions:
E.g.:
lambda x: [f1(x), f2(x), f3(x), x+1]
This will not work with statements.
Since 0.14.1, you can now do nlargest
and nsmallest
on a groupby
object:
In [23]: df.groupby('id')['value'].nlargest(2)
Out[23]:
id
1 2 3
1 2
2 6 4
5 3
3 7 1
4 8 1
dtype: int64
There's a slight weirdness that you get the original index in there as well, but this might be really useful depending on what your original index was.
If you're not interested in it, you can do .reset_index(level=1, drop=True)
to get rid of it altogether.
(Note: From 0.17.1 you'll be able to do this on a DataFrameGroupBy too but for now it only works with Series
and SeriesGroupBy
.)
Here's another method if you can safely use CSS3's transform
property:
.fixed-horizontal-center
{
position: fixed;
top: 100px; /* or whatever top you need */
left: 50%;
width: auto;
-webkit-transform: translateX(-50%);
-moz-transform: translateX(-50%);
-ms-transform: translateX(-50%);
-o-transform: translateX(-50%);
transform: translateX(-50%);
}
...or if you want both horizontal AND vertical centering:
.fixed-center
{
position: fixed;
top: 50%;
left: 50%;
width: auto;
height: auto;
-webkit-transform: translate(-50%,-50%);
-moz-transform: translate(-50%,-50%);
-ms-transform: translate(-50%,-50%);
-o-transform: translate(-50%,-50%);
transform: translate(-50%,-50%);
}
I altered the jQuery plugin posted above so it would work on live elements.
(function ($) {
$.fn.disableSelection = function () {
return this.each(function () {
if (typeof this.onselectstart != 'undefined') {
this.onselectstart = function() { return false; };
} else if (typeof this.style.MozUserSelect != 'undefined') {
this.style.MozUserSelect = 'none';
} else {
this.onmousedown = function() { return false; };
}
});
};
})(jQuery);
Then you could so something like:
$(document).ready(function() {
$('label').disableSelection();
// Or to make everything unselectable
$('*').disableSelection();
});
C does not have an implementation of for-each
. When parsing an array as a point the receiver does not know how long the array is, thus there is no way to tell when you reach the end of the array.
Remember, in C int*
is a point to a memory address containing an int. There is no header object containing information about how many integers that are placed in sequence. Thus, the programmer needs to keep track of this.
However, for lists, it is easy to implement something that resembles a for-each
loop.
for(Node* node = head; node; node = node.next) {
/* do your magic here */
}
To achieve something similar for arrays you can do one of two things.
The following is an example of such struct:
typedef struct job_t {
int count;
int* arr;
} arr_t;
I was being able to ping my connection but was STILL getting the 'connection refused' error. Turns out I was pinging myself! That's what the problem was.

/** POST: add a new hero to the database */
addHero (hero: Hero): Observable<Hero> {
return this.http.post<Hero>(this.heroesUrl, hero, httpOptions)

}
/** GET heroes from the server */
getHeroes (): Observable<Hero[]> {
return this.http.get<Hero[]>(this.heroesUrl)
.pipe(

);
}
it's because of pipeable/lettable operators

For JavaScript developers, the general rule is as follows:
rxjs: Creation methods, types, schedulers and utilities
import { Observable, Subject, asapScheduler, pipe, of, from, interval, merge, fromEvent } from 'rxjs';
rxjs/operators: All pipeable operators:
import { map, filter, scan } from 'rxjs/operators';
rxjs/webSocket: The web socket subject implementation
import { webSocket } from 'rxjs/webSocket';
rxjs/ajax: The Rx ajax implementation
import { ajax } from 'rxjs/ajax';
rxjs/testing: The testing utilities
import { TestScheduler } from 'rxjs/testing';
and for backward compatability you can use rxjs-compat
This worked. The first row had column names in it.
COPY wheat FROM 'wheat_crop_data.csv' DELIMITER ';' CSV HEADER
for me setting the Dimensions to use % is what worked for me
width:'100%'
jsonData = """{"from": {"id": "8", "name": "Mary Pinter"}, "message": "How ARE you?", "comments": {"count": 0}, "updated_time": "2012-05-01", "created_time": "2012-05-01", "to": {"data": [{"id": "1543", "name": "Honey Pinter"}, {"name": "Joe Schmoe"}]}, "type": "status", "id": "id_7"}"""
def getTargetIds(jsonData):
data = json.loads(jsonData)
for dest in data['to']['data']:
print("to_id:", dest.get('id', 'null'))
Try it:
>>> getTargetIds(jsonData)
to_id: 1543
to_id: null
Or, if you just want to skip over values missing ids instead of printing 'null'
:
def getTargetIds(jsonData):
data = json.loads(jsonData)
for dest in data['to']['data']:
if 'id' in to_id:
print("to_id:", dest['id'])
So:
>>> getTargetIds(jsonData)
to_id: 1543
Of course in real life, you probably don't want to print
each id, but to store them and do something with them, but that's another issue.
I faced same problem in emulator, but I solved it like this:
Create new emulator with x86_64 system image(ABI)
That's it.
This error indicates the system(Device) not capable for run the application.
I hope this is helpful to someone.
After a recent update on my Ubuntu 16.04 system I have also started getting this error when trying to run convert on .ps files to convert them into pdfs.
This fix worked for me:
In a terminal run:
sudo gedit /etc/ImageMagick-6/policy.xml
This should open the policy.xml file in the gedit text editor. If it doesn't, your image magick might be installed in a different place. Then change
rights="none"
to
rights="read | write"
for PDF, EPS and PS lines near the bottom of the file. Save and exit, and image magick should then work again.
The best way I have found is to use the initComplete method as it fires after the data has been retrieved and renders the table. NOTE this only fires once though.
$("#tableOfData").DataTable({
"pageLength": 50,
"ajax":{
url: someurl,
dataType : "json",
type: "post",
"data": {data to be sent}
},
"initComplete":function( settings, json){
console.log(json);
// call your function here
}
});
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.
Just install the updated versions of all of them.
apt-get install -y gnupg2 gnupg gnupg1
int rotation = getWindowManager().getDefaultDisplay().getRotation();
this will gives all orientation like normal and reverse
and handle it like
int angle = 0;
switch (rotation) {
case Surface.ROTATION_90:
angle = -90;
break;
case Surface.ROTATION_180:
angle = 180;
break;
case Surface.ROTATION_270:
angle = 90;
break;
default:
angle = 0;
break;
}
window.location is an object, not a string so you need to use window.location.href to get the actual string url
if (window.location.href.indexOf("?added-to-cart=555") >= 0) {
alert("found it");
}
just select '0' as the value for the desired column
Your understanding is correct.
You would do this in many cases. One example is in a relationship like OrderHeader
and OrderDetail
. The PK in OrderHeader
might be OrderNumber
. The PK in OrderDetail
might be OrderNumber
AND LineNumber
. If it was either of those two, it would not be unique, but the combination of the two is guaranteed unique.
The alternative is to use a generated (non-intelligent) primary key, for example in this case OrderDetailId
. But then you would not always see the relationship as easily. Some folks prefer one way; some prefer the other way.
