You can use the sDom
option for this.
Default with search input in its own div:
sDom: '<"search-box"r>lftip'
If you use jQuery UI (bjQueryUI
set to true
):
sDom: '<"search-box"r><"H"lf>t<"F"ip>'
The above will put the search/filtering input
element into it's own div
with a class named search-box
that is outside of the actual table.
Even though it uses its special shorthand syntax it can actually take any HTML you throw at it.
Do you need the second batch file to run asynchronously? Typically one batch file runs another synchronously with the call
command, and the second one would share the first one's window.
You can use start /b
second.bat to launch a second batch file asynchronously from your first that shares your first one's window. If both batch files write to the console simultaneously, the output will be overlapped and probably indecipherable. Also, you'll want to put an exit
command at the end of your second batch file, or you'll be within a second cmd
shell once everything is done.
This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.
Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.
In this case I'd ask why you're including both cstdlib
and stdlib.h
; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib
puts them in the namespace std
in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!
Anyway, your use of using namespace std
(which I would recommend against, in future) means that std::system
from cstdlib
now conflicts with system
from stdlib.h
. I can't explain what's going on with std::cout
and std::cin
.
Try removing #include <stdlib.h>
and see what happens.
If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.
You are calling DoDownloadAsync() but you don't wait it. So your program going to the next line. But there is another problem, Async methods should return Task
or Task<T>
, if you return nothing and you want your method will be run asyncronously you should define your method like this:
private static async Task DoDownloadAsync() { WebClient w = new WebClient(); string txt = await w.DownloadStringTaskAsync("http://www.google.com/"); Debug.WriteLine(txt); }
And in Main method you can't await for DoDownloadAsync
, because you can't use await keyword in non-async function, and you can't make Main
async. So consider this:
var result = DoDownloadAsync(); Debug.WriteLine("DoDownload done"); result.Wait();
BigInteger has a constructor where you can pass string as an argument.
try below,
private void sum(String newNumber) {
// BigInteger is immutable, reassign the variable:
this.sum = this.sum.add(new BigInteger(newNumber));
}
In Python 3, print is a function, you need to call it like print("hello world")
.
It does work indeed. Issue was with my less compiler. It was compiled in to:
.container {
min-height: calc(-51vh);
}
Fixed with the following code in less file:
.container {
min-height: calc(~"100vh - 150px");
}
Thanks to this link: Less Aggressive Compilation with CSS3 calc
I always go back to this article SQL Server 2005 XQuery and XML-DML - Part 1 to know how to use the XML features in SQL Server 2005.

This help
target will only print targets which have ##
followed by a description. This allows for documenting both public and private targets. Using the .DEFAULT_GOAL
makes the help more discoverable.
Only sed
, xargs
and printf
used which are pretty common.
Using the < $(MAKEFILE_LIST)
allows for the makefile to be called something other than Makefile
for instance Makefile.github
You can customize the output to suit your preference in the printf
. This example is set up to match the OP's request for rake
style output
When cutting and pasting the below make file, don't forget to change the 4 spaces indentation to tabs.
# vim:ft=make
# Makefile
.DEFAULT_GOAL := help
.PHONY: test help
help: ## these help instructions
@sed -rn 's/^([a-zA-Z_-]+):.*?## (.*)$$/"\1" "\2"/p' < $(MAKEFILE_LIST) | xargs printf "make %-20s# %s\n"
lint: ## style, bug and quality checker
pylint src test
private: # for internal usage only
@true
test: private ## run pytest with coverage
pytest --cov test
Here is the output from the Makefile
above. Notice the private
target doesn't get output because it only has a single #
for it's comment.
$ make
make help # these help instructions
make lint # style, bug and quality checker
make test # run pytest with coverage
This answer to a similar question describes how to extend the properties plugin so it can use a remote descriptor for the properties file. The descriptor is basically a jar artifact containing a properties file (the properties file is included under src/main/resources).
The descriptor is added as a dependency to the extended properties plugin so it is on the plugin's classpath. The plugin will search the classpath for the properties file, read the file''s contents into a Properties instance, and apply those properties to the project's configuration so they can be used elsewhere.

I'm rather shocked that this has not been answered since the solution is very simple.
As mentioned in previous posts, you would not want to convert it using C#, but just once. This is easy to do with PuTTYGen.
Enjoy!
Use npm install packageName --save
this will add package in dependencies, if you use npm install packageName --save-dev
then it devDependencies.
npm install packageName --save-dev
should be used for adding packages for development purpose. Like adding TDD packages (Chai, mocha, etc). Which are used in development and not in production.
DateTime.UtcNow.ToString("s", System.Globalization.CultureInfo.InvariantCulture)
should give you what you are looking for as the "s" format specifier is described as a sortable date/time pattern; conforms to ISO 8601.
EDIT: To get the additional Z
at the end as the OP requires, use "o"
instead of "s"
.
I'm not sure how they're functionally different. My current batch of OS X browsers don't show any difference.
I would assume they are all functionally the same due to legacy HTML attribute handling. Back in the day, any flag (Boolean) attribute need only be present, sans value, eg
<input readonly>
<option selected>
When XHTML came along, this syntax wasn't valid and values were required. Whilst the W3 specified using the attribute name as the value, I'm guessing most browser vendors decided to simply check for attribute existence.
You can use
Dispatcher.Invoke(Delegate, object[])
on the Application
's (or any UIElement
's) dispatcher.
You can use it for example like this:
Application.Current.Dispatcher.Invoke(new Action(() => { /* Your code here */ }));
or
someControl.Dispatcher.Invoke(new Action(() => { /* Your code here */ }));
I had a similar problem when using TFS 2017. I was not able to push or pull GIT repositories. Eventually I reinstalled TFS 2017, making sure that I installed TFS 2017 with an SSH Port different from 22 (in my case, I chose 8022). After that, push and pull became possible against TFS using SSH.
Paste the following at the top of your JavaScript (before using the console):
/**
* Protect window.console method calls, e.g. console is not defined on IE

var noop = function() {};
while (length--) {

The function closure wrapper is to scope the variables as to not define any variables. This guards against both undefined console

(and other missing methods).
EDIT: I noticed that HTML5 Boilerplate uses similar code in its js/plugins.js file, if you're looking for a solution that will (probably) be kept up-to-date.
This does not work in Python 3.
You can use functools cmp_to_key to have old-style comparison functions work though.
from functools import cmp_to_key
def cmp_items(a, b):
if a.foo > b.foo:
return 1
elif a.foo == b.foo:
return 0
else:
return -1
cmp_items_py3 = cmp_to_key(cmp_items)
alist.sort(cmp_items_py3)
I'm very surprised no one has mentioned this one liner. It's simple, concise and performs slightly better than str.split(target, -1).length-1
public static int count(String str, String target) {
return (str.length() - str.replace(target, "").length()) / target.length();
}

I know it's an old question, but when I did this search, I find a lot of related question, but I did not find a really clear response. So I make my own implementation of a dialogbox/messagebox/popin, and I share it!

You can use it like this:
public RelayCommand YesNoMessageBoxCommand { get; private set; }
async void YesNoMessageBox()
{
var result = await _Service.ShowMessage("This is the content of the message box", "This is the title", System.Windows.MessageBoxButton.YesNo);
if (result == System.Windows.MessageBoxResult.Yes)
// [...]
}
Or like this if you want more sophisticated popin :
var result = await _Service.ShowCustomMessageBox(new MyMessageBoxViewModel { /* What you want */ });
And it is showing things like this :
To avoid remembering what you need to do each time you get the message:

You can use the following script which sets origin as upstream for the current branch you are in.
In my case I almost never set something else than origin as the default upstream. Also I almost always keep the same branch name for local and remote branch. So the following fits me:
#!/bin/bash
# scriptname: git-branch-set-originupstream
current_branch="$(git branch | grep -oP '(?<=^\* )(.*)$')"
upstream="origin/$current_branch"
git branch -u "$upstream"
The complete article that works for me: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Base64_encoding_and_decoding
The part where we encode from Unicode/UTF-8 is
function utf8_to_b64( str ) {
return window.btoa(unescape(encodeURIComponent( str )));
}
function b64_to_utf8( str ) {
return decodeURIComponent(escape(window.atob( str )));
}
// Usage:
utf8_to_b64('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64_to_utf8('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"
This is one of the most used methods nowadays.
System.Text.ASCIIEncoding.Unicode.GetByteCount(yourString);

System.Text.ASCIIEncoding.ASCII.GetByteCount(yourString);

I've had problems with inserting images in R Markdown. If I do the entire URL: C:/Users/Me/Desktop/Project/images/image.png
it tends to work. Otherwise, I have to put the markdown in either the same directory as the image or in an ancestor directory to it. It appears that the declared knitting directory is ignored when referencing images.
I was stuck in this and I solved it with a hidden field:
<form method="post" action="test.php">
<input type="hidden" name="ID" value"">
</form>
In value
you can add whatever you want to add.
In test.php you can retrieve the value through $_Post[ID]
.
Heres an implementation with little memory overhead at the cost of not being as compact as the rest.
values = [ {'id':2,'name':'hanna', 'age':30},
{'id':1,'name':'john', 'age':34},
{'id':1,'name':'john', 'age':34},
{'id':2,'name':'hanna', 'age':30},
{'id':1,'name':'john', 'age':34},]
count = {}
index = 0
while index < len(values):
if values[index]['id'] in count:
del values[index]
else:
count[values[index]['id']] = 1
index += 1
output:
[{'age': 30, 'id': 2, 'name': 'hanna'}, {'age': 34, 'id': 1, 'name': 'john'}]
Just for fun, don't do this!
$.fn.transitiondone = function () {
return this.each(function () {
var $this = $(this);
setTimeout(function () {
$this.trigger('transitiondone');

});
};
$('div').on('mousedown', function (e) {
$(this).addClass('bounce').transitiondone();
});
$('div').on('transitiondone', function () {
$(this).removeClass('bounce');

string[]
is an array (vector) of strings
string
is just a string (a list/array of characters)
Depending on how you want to convert this, the canonical answer could be:
return String.Join(" ", myStringArray);
return new []{ myString };
I always do input prompts, like this:
<input style="color: #C0C0C0;" value="[email protected]"
onfocus="this.value=''; this.style.color='#000000'">
Of course, if your user fills in the field, changes focus and comes back to the field, the field will once again be cleared. If you do it like that, be sure that's what you want. You can make it a one time thing by setting a semaphore, like this:
<script language = "text/Javascript">
cleared[0] = cleared[1] = cleared[2] = 0; //set a cleared flag for each field
function clearField(t){ //declaring the array outside of the
if(! cleared[t.id]){ // function makes it static and global
cleared[t.id] = 1; // you could use true and false, but that's more typing
t.value=''; // with more chance of typos
t.style.color='#000000';
}
}
</script>
Your <input> field then looks like this:
<input id = 0; style="color: #C0C0C0;" value="[email protected]"
onfocus=clearField(this)>
You're looking for is called an IDENTITY column:
create table student (
sid integer not null GENERATED ALWAYS AS IDENTITY (START WITH 1 INCREMENT BY 1)
,sname varchar(30)
,PRIMARY KEY (sid)
);
A sequence is another option for doing this, but you need to determine which one is proper for your particular situation. Read this for more information comparing sequences to identity columns.
For macOS, you don't need install any plugin or mouse.

I answered a similar question before on how to run a Docker container inside Docker.
To run docker inside docker is definitely possible. The main thing is that you
run
the outer container with extra privileges (starting with--privileged=true
) and then install docker in that container.Check this blog post for more info: Docker-in-Docker.
One potential use case for this is described in this entry. The blog describes how to build docker containers within a Jenkins docker container.
However, Docker inside Docker it is not the recommended approach to solve this type of problems. Instead, the recommended approach is to create "sibling" containers as described in this post
So, running Docker inside Docker was by many considered as a good type of solution for this type of problems. Now, the trend is to use "sibling" containers instead. See the answer by @predmijat on this page for more info.
It looks like you're passing in Null for every argument except for PropertyValueID and DropDownOptionID, right? I don't think any of your IF statements will fire if only these two values are not-null. In short, I think you have a logic error.
Other than that, I would suggest two things...
First, instead of testing for NULL, use this kind syntax on your if statements (it's safer)...
ELSE IF ISNULL(@UnitValue, 0) != 0 AND ISNULL(@UnitOfMeasureID, 0) = 0
Second, add a meaningful PRINT statement before each UPDATE. That way, when you run the sproc in MSSQL, you can look at the messages and see how far it's actually getting.
You declared the constructor blowfish as this:
Blowfish(BlowfishAlgorithm algorithm);
So this line cannot exist (without further initialization later):
Blowfish _blowfish;
since you passed no parameter. It does not understand how to handle a parameter-less declaration of object "BlowFish" - you need to create another constructor for that.
You may try to make the folder which include jsp-s become the source folder of eclipse, that solved the same problem of mine. As below:
- open project's properties.(right click project, then choose the Properties)
- choose Java Build Path, select the Source tab, click Add Folder and choose the folder including your jsp-s, OK
It's trivial when you know how:

import finplot as fplt
fplt.candlestick_ochl(df[['Open','Close','High','Low']])
fplt.show()
In Clean Code: A Handbook of Agile Software Craftsmanship there is an explicit recommendation against the usage of this prefix:
You also don't need to prefix member variables with
m_
anymore. Your classes and functions should be small enough that you don't need them.
There is also an example (C# code) of this:
Bad practice:
public class Part
{
private String m_dsc; // The textual description
void SetName(string name)
{
m_dsc = name;
}
}
Good practice:
public class Part
{
private String description;
void SetDescription(string description)
{
this.description = description;
}
}
We count with language constructs to refer to member variables in the case of explicitly ambiguity (i.e., description
member and description
parameter): this
.
Other people have suggested using in.nextLine()
to clear the buffer, which works for single-line input. As comments point out, however, sometimes System.in input can be multi-line.
You can instead create a new Scanner object where you want to clear the buffer if you are using System.in and not some other InputStream.
in = new Scanner(System.in);
If you do this, don't call in.close()
first. Doing so will close System.in, and so you will get NoSuchElementExceptions on subsequent calls to in.nextInt();
System.in probably shouldn't be closed during your program.
(The above approach is specific to System.in. It might not be appropriate for other input streams.)
If you really need to close your Scanner object before creating a new one, this StackOverflow answer suggests creating an InputStream wrapper for System.in that has its own close() method that doesn't close the wrapped System.in stream. This is overkill for simple programs, though.
something like this?
DECLARE maxval, val, @ind INT;
SELECT MAX(ID) as maxval FROM table;
while (ind <= maxval ) DO
select `value` as val from `table` where `ID`=ind;
CALL fn(val);
SET ind = ind+1;
end while;

delete
will delete the object property, but will not reindex the array or update its length. This makes it appears as if it is undefined:
> myArray = ['a', 'b', 'c', 'd']
["a", "b", "c", "d"]
> delete myArray[0]
true
> myArray[0]
undefined
Note that it is not in fact set to the value undefined
, rather the property is removed from the array, making it appear undefined. The Chrome dev tools make this distinction clear by printing empty
when logging the array.
> myArray[0]
undefined
> myArray
[empty, "b", "c", "d"]
myArray.splice(start, deleteCount)
actually removes the element, reindexes the array, and changes its length.
> myArray = ['a', 'b', 'c', 'd']
["a", "b", "c", "d"]
> myArray.splice(0, 2)
["a", "b"]
> myArray
["c", "d"]
Actually your $product
has no data because the Eloquent
model returns NULL. It's probably because you have used whereOwnerAndStatus
which seems wrong and if there were data in $product
then it would not work in your first example because get()
returns a collection of multiple models but that is not the case. The second example throws error because foreach
didn't get any data. So I think it should be something like this:
$owner = Input::get('owner');
$count = Input::get('count');
$products = Product::whereOwner($owner, 0)->take($count)->get();
Further you may also make sure if $products
has data:
if($product) {
return View:make('viewname')->with('products', $products);
}
Then in the view
:
foreach ($products as $product) {
// If Product has sku (collection object, probably related models)
foreach ($product->sku as $sku) {
// Code Here
}
}

In case of float values with characters 'e' '+' it errors out if we try to convert in decimal. ('2.81104e+006'). It still pass ISNUMERIC test.
SELECT ISNUMERIC('2.81104e+006')
returns 1
.
SELECT convert(decimal(15,2), '2.81104e+006')
returns
error: Error converting data type varchar to numeric.
And
SELECT try_convert(decimal(15,2), '2.81104e+006')
returns NULL
.
SELECT convert(float, '2.81104e+006')
returns the correct value 2811040

You can use $x
in the Chrome javascript console. No extensions needed.
ex: $x("//img")
Also the search box in the web inspector will accept xpath
If you want an alert to appear after a certain about time, you can use this code:
setTimeout(function() { alert("my message"); }, time);
If you want an alert to appear and disappear after a specified interval has passed, then you're out of luck. When an alert
has fired, the browser stops processing the javascript code until the user clicks "ok". This happens again when a confirm
or prompt
is shown.
If you want the appear/disappear behavior, then I would recommend using something like jQueryUI's dialog widget. Here's a quick example on how you might use it to achieve that behavior.
var dialog = $(foo).dialog('open');
setTimeout(function() { dialog.dialog('close'); }, time);
You can use the username variable: %USERNAME%
As far as I can tell, GitHub does not provide shell access, so I'm curious about how you managed to log in in the first place.
$ ssh -T [email protected]
Hi username! You've successfully authenticated, but GitHub does not provide
shell access.
You have to clone your repository locally, make the change there, and push the change to GitHub.
$ git clone [email protected]:username/reponame.git
$ cd reponame
$ git mv README README.md
$ git commit -m "renamed"
$ git push origin master
Just put a pair of double quotes around your file name like this:
this.Response.AddHeader("Content-disposition", $"attachment; filename=\"{outputFileName}\"");
I realize that an answer was already accepted for this, but from a "strictly *nix purist angle" it seems like the right tool for the job is pcregrep
, which doesn't seem to have been mentioned yet. Try changing the lines:
echo $f | grep -oEi '[0-9]+_([a-z]+)_[0-9a-z]*'
name=$?
to the following:
name=$(echo $f | pcregrep -o1 -Ei '[0-9]+_([a-z]+)_[0-9a-z]*')
to get only the contents of the capturing group 1.
The pcregrep
tool utilizes all of the same syntax you've already used with grep
, but implements the functionality that you need.
The parameter -o
works just like the grep
version if it is bare, but it also accepts a numeric parameter in pcregrep
, which indicates which capturing group you want to show.
With this solution there is a bare minimum of change required in the script. You simply replace one modular utility with another and tweak the parameters.
Interesting Note: You can use multiple -o arguments to return multiple capture groups in the order in which they appear on the line.
Corresponding to INSERT (Transact-SQL) (SQL Server 2005) you can't omit INSERT INTO dbo.Blah
and have to specify it every time or use another syntax/approach,
For me, I managed to make it work that way. I deployed the automatic click in 5000 milliseconds and then closed the loop after 1000 milliseconds. Then there was only 1 automatic click.
<script> var myVar = setInterval(function ({document.getElementById("test").click();}, 500)); setInterval(function () {clearInterval(myVar)}, 1000));</script>
I think you can use db.collection.distinct(fields,query)
You will be able to get the distinct values in your case for NetworkID.
It should be something like this :
Db.collection.distinct('NetworkID')
You might have to change the name of your main activity "android:label" also, as explained in Naming my application in android
Behaviour subjects. I wrote a blog about that.
import { BehaviorSubject } from 'rxjs/BehaviorSubject';
private noId = new BehaviorSubject<number>(0);
defaultId = this.noId.asObservable();
newId(urlId) {
this.noId.next(urlId);
}
In this example i am declaring a noid behavior subject of type number. Also it is an observable. And if "something happend" this will change with the new(){} function.
So, in the sibling's components, one will call the function, to make the change, and the other one will be affected by that change, or vice-versa.
For example, I get the id from the URL and update the noid from the behavior subject.
public getId () {
const id = +this.route.snapshot.paramMap.get('id');
return id;
}
ngOnInit(): void {
const id = +this.getId ();
this.taskService.newId(id)
}
And from the other side, I can ask if that ID is "what ever i want" and make a choice after that, in my case if i want to delte a task, and that task is the current url, it have to redirect me to the home:
delete(task: Task): void {
//we save the id , cuz after the delete function, we gonna lose it
const oldId = task.id;
this.taskService.deleteTask(task)
.subscribe(task => { //we call the defaultId function from task.service.
this.taskService.defaultId //here we are subscribed to the urlId, which give us the id from the view task
.subscribe(urlId => {
this.urlId = urlId ;
if (oldId == urlId ) {
// Location.call('/home');
this.router.navigate(['/home']);
}
})
})
}

you can also use just like this in newer version of sql,

month('2001-02-16 20:38:40') as month,
day('2001-02-16 20:38:40') as day,
hour('2001-02-16 20:38:40') as hour,
minute('2001-02-16 20:38:40') as minute
you have id="#message"
... should be id="message"
The main goals of my code are:
The first property is achieved by taking a 64 bit value modulo the alphabet size. For small alphabets (such as the 62 characters from the question) this leads to negligible bias. The second and third property are achieved by using RNGCryptoServiceProvider
instead of System.Random
.
using System;
using System.Security.Cryptography;
public static string GetRandomAlphanumericString(int length)
{
const string alphanumericCharacters =
"ABCDEFGHIJKLMNOPQRSTUVWXYZ" +
"abcdefghijklmnopqrstuvwxyz" +
"0123456789";
return GetRandomString(length, alphanumericCharacters);
}
public static string GetRandomString(int length, IEnumerable<char> characterSet)
{
if (length < 0)
throw new ArgumentException("length must not be negative", "length");
if (length > int.MaxValue / 8) // 250 million chars ought to be enough for anybody
throw new ArgumentException("length is too big", "length");
if (characterSet == null)
throw new ArgumentNullException("characterSet");
var characterArray = characterSet.Distinct().ToArray();
if (characterArray.Length == 0)
throw new ArgumentException("characterSet must not be empty", "characterSet");
var bytes = new byte[length * 8];
new RNGCryptoServiceProvider().GetBytes(bytes);
var result = new char[length];
for (int i = 0; i < length; i++)
{
ulong value = BitConverter.ToUInt64(bytes, i * 8);
result[i] = characterArray[value % (uint)characterArray.Length];
}
return new string(result);
}
(This is a copy of my answer to How can I generate random 8 character, alphanumeric strings in C#?)
var str = 'abcdefghijkl';_x000D_
console.log(str.match(/.{1,3}/g));
_x000D_
Note: Use {1,3}
instead of just {3}
to include the remainder for string lengths that aren't a multiple of 3, e.g:
console.log("abcd".match(/.{1,3}/g)); // ["abc", "d"]
_x000D_
A couple more subtleties:
.
won't capture those. Use /[\s\S]{1,3}/
instead. (Thanks @Mike).match()
will return null
when you may be expecting an empty array. Protect against this by appending || []
.So you may end up with:
var str = 'abcdef \t\r\nghijkl';_x000D_
var parts = str.match(/[\s\S]{1,3}/g) || [];_x000D_
console.log(parts);_x000D_

It really depends on how you write your bash scripts. If your /bin/sh

, some features are unavailable.
If you want bash-specific, non-POSIX features, use #!/bin/bash

Firstly, understand that DateTime
objects aren't formatted. They just store the Year, Month, Day, Hour, Minute, Second, etc as a numeric value and the formatting occurs when you want to represent it as a string somehow. You can compare DateTime
objects without formatting them.
To compare an input date with DateTime.Now
, you need to first parse the input into a date and then compare just the Year/Month/Day portions:
DateTime inputDate;
if(!DateTime.TryParse(inputString, out inputDate))
throw new ArgumentException("Input string not in the correct format.");
if(inputDate.Date == DateTime.Now.Date) {
// Same date!
}
You need to access the matches in order to get at the SDI number. Here is a function that will do it (assuming there is only 1 SDI number per cell).
For the regex, I used "sdi followed by a space and one or more numbers". You had "sdi followed by a space and zero or more numbers". You can simply change the + to * in my pattern to go back to what you had.
Function ExtractSDI(ByVal text As String) As String
Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")
RE.pattern = "(sdi \d+)"
RE.Global = True
RE.IgnoreCase = True
Set allMatches = RE.Execute(text)
If allMatches.count <> 0 Then
result = allMatches.Item(0).submatches.Item(0)
End If
ExtractSDI = result
End Function
If a cell may have more than one SDI number you want to extract, here is my RegexExtract function. You can pass in a third paramter to seperate each match (like comma-seperate them), and you manually enter the pattern in the actual function call:
Ex) =RegexExtract(A1, "(sdi \d+)", ", ")
Here is:
Function RegexExtract(ByVal text As String, _
ByVal extract_what As String, _
Optional seperator As String = "") As String
Dim i As Long, j As Long
Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")
RE.pattern = extract_what
RE.Global = True
Set allMatches = RE.Execute(text)
For i = 0 To allMatches.count - 1
For j = 0 To allMatches.Item(i).submatches.count - 1
result = result & seperator & allMatches.Item(i).submatches.Item(j)
Next
Next
If Len(result) <> 0 Then
result = Right(result, Len(result) - Len(seperator))
End If
RegexExtract = result
End Function
*Please note that I have taken "RE.IgnoreCase = True" out of my RegexExtract, but you could add it back in, or even add it as an optional 4th parameter if you like.
I know that this question has been answered, And all the answers are nice. But I wanted to add my two cents to this question for people who have similar (but not exactly the same) problem.
In a more general way, we can do something like this:
$('body').click(function(evt){
if(!$(evt.target).is('#menu_content')) {
//event handling code
}
});
This way we can handle not only events fired by anything except element with id menu_content
but also events that are fired by anything except any element that we can select using CSS selectors.
For instance in the following code snippet I am getting events fired by any element except all <li>
elements which are descendants of div element with id myNavbar
.
$('body').click(function(evt){
if(!$(evt.target).is('div#myNavbar li')) {
//event handling code
}
});

const angleInRadians = angleInDegrees => (angleInDegrees - 90) * (Math.PI / 180.0);
const polarToCartesian = (centerX, centerY, radius, angleInDegrees) => {
const a = angleInRadians(angleInDegrees);
return {
x: centerX + (radius * Math.cos(a)),
y: centerY + (radius * Math.sin(a)),
};
};
const arc = (x, y, radius, startAngle, endAngle) => {
const fullCircle = endAngle - startAngle === 360;
const start = polarToCartesian(x, y, radius, endAngle - 0.01);
const end = polarToCartesian(x, y, radius, startAngle);
const arcSweep = endAngle - startAngle <= 180 ? '0' : '1';
const d = [
'M', start.x, start.y,
'A', radius, radius, 0, arcSweep, 0, end.x, end.y,
].join(' ');
if (fullCircle) d.push('z');
return d;
};

SYSDATE
is an Oracle only function.
The ANSI standard defines current_date
or current_timestamp
which is supported by Postgres and documented in the manual:
http://www.postgresql.org/docs/current/static/functions-datetime.html#FUNCTIONS-DATETIME-CURRENT
(Btw: Oracle supports CURRENT_TIMESTAMP
as well)
You should pay attention to the difference between current_timestamp
, statement_timestamp()
and clock_timestamp()
(which is explained in the manual, see the above link)
This statement:
select up_time from exam where up_time like sysdate
Does not make any sense at all. Neither in Oracle nor in Postgres. If you want to get rows from "today", you need something like:
select up_time
from exam
where up_time = current_date
Note that in Oracle you would probably want trunc(up_time) = trunc(sysdate)
to get rid of the time part that is always included in Oracle.

Then try :
helper.link_to("test", app.spree.product_path(Spree::Product.first), method: :get)
output
Spree::Product Load (0.4ms) SELECT "spree_products".* FROM "spree_products" WHERE "spree_products"."deleted_at" IS NULL ORDER BY "spree_products"."id" ASC LIMIT 1
=> "<a data-method=\"get\" href=\"/products/this-is-the-title\">test</a>"
this.setState({ abc.xyz: 'new value' });
syntax is not allowed.
You have to pass the whole object.
this.setState({abc: {xyz: 'new value'}});
If you have other variables in abc
var abc = this.state.abc;
abc.xyz = 'new value';
this.setState({abc: abc});
You can have ordinary variables, if they don't rely on this.props and this.state
.

System.getProperties()
can be overridden by calls to System.setProperty(String key, String value)
or with command line parameters -Dfile.separator=/
File.separator
gets the separator for the default filesystem.
FileSystems.getDefault()
gets you the default filesystem.
FileSystem.getSeparator()
gets you the separator character for the filesystem. Note that as an instance method you can use this to pass different filesystems to your code other than the default, in cases where you need your code to operate on multiple filesystems in the one JVM.
Maybe you can use the script i am using to retrieve a certain cell value from another sheet back to a specific sheet.
Sub reviewRow()
Application.ScreenUpdating = False
Results = MsgBox("Do you want to View selected row?", vbYesNo, "")
If Results = vbYes And Range("C10") > 1 Then
i = Range("C10") //this is where i put the row number that i want to retrieve or review that can be changed as needed
Worksheets("Sheet1").Range("C6") = Worksheets("Sheet2").Range("C" & i) //sheet names can be changed as necessary
End if
Application.ScreenUpdating = True
End Sub
You can make a form using this and personalize it as needed.
For just one run (from the unix shell prompt):
$ PORT=1234 node app.js
More permanently:
$ export PORT=1234
$ node app.js
In Windows:
set PORT=1234
In Windows PowerShell:
$env:PORT = 1234
I saw this occur when the number of connections to my server exceeded Chrome's max-connections-per-server limit of 6.

I just wanted to share an improved version of Minhas Kamal's code because although it worked well enough for most applications, I had a few issues with it still. Two highly important things to remember:
Below, you can see my revisions to his code:

with the current version of mongoose (1.6.0) if you only want to sort by one column, you have to drop the array and pass the object directly to the sort() function:
Content.find().sort('created', 'descending').execFind( ... );
took me some time, to get this right :(
From JQuery Documentation
The jqXHR objects returned by $.ajax()
as of jQuery 1.5 implement the Promise interface, giving them all the properties, methods, and behavior of a Promise (see Deferred object for more information). These methods take one or more function arguments that are called when the $.ajax()
request terminates. This allows you to assign multiple callbacks on a single request, and even to assign callbacks after the request may have completed. (If the request is already complete, the callback is fired immediately.) Available Promise methods of the jqXHR object include:
jqXHR.done(function( data, textStatus, jqXHR ) {});
An alternative construct to the success callback option, refer to deferred.done()
for implementation details.
jqXHR.fail(function( jqXHR, textStatus, errorThrown ) {});
An alternative construct to the error callback option, the .fail()
method replaces the deprecated .error() method. Refer to deferred.fail() for implementation details.
jqXHR.always(function( data|jqXHR, textStatus, jqXHR|errorThrown ) { });
(added in jQuery 1.6)
An alternative construct to the complete callback option, the .always()
method replaces the deprecated .complete()
method.
In response to a successful request, the function's arguments are the same as those of .done()
: data, textStatus, and the jqXHR object. For failed requests the arguments are the same as those of .fail()
: the jqXHR object, textStatus, and errorThrown. Refer to deferred.always()
for implementation details.
jqXHR.then(function( data, textStatus, jqXHR ) {}, function( jqXHR, textStatus, errorThrown ) {});
Incorporates the functionality of the .done()
and .fail()
methods, allowing (as of jQuery 1.8) the underlying Promise to be manipulated. Refer to deferred.then()
for implementation details.
Deprecation Notice: The
jqXHR.success()
,jqXHR.error()
, andjqXHR.complete()
callbacks are removed as of jQuery 3.0. You can usejqXHR.done()
,jqXHR.fail()
, andjqXHR.always()
instead.
For those interested in disabling it in codeship, run this script before running tests:

Possible solution with string_view

std::cout << std::endl;
}
It is possible by recreating table.Its work for me please follow following step:

Another easy way to do this is by using the following syntax to iterate through the object, keeping access to the key and value:
for(var key in object){
console.log(key + ' - ' + object[key])
}
so for yours:
for(var key in obj){
console.log(key + ' - ' + obj[key])
}
In cell D2 and copied down:
=IF(COUNTIF($A$2:$A$5,C2)=0,"",VLOOKUP(C2,$A$2:$B$5,2,FALSE))
According to the release-notes, Java 11 removed the Java EE modules:
java.xml.bind (JAXB) - REMOVED
See JEP 320 for more info.
You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-core</artifactId>
<version>2.3.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.3.0</version>
</dependency>
Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:
<dependency>
<groupId>jakarta.xml.bind</groupId>
<artifactId>jakarta.xml.bind-api</artifactId>
<version>2.3.3</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.3.3</version>
<scope>runtime</scope>
</dependency>
Use latest release of Eclipse Implementation of JAXB 3.0.0:
<dependency>
<groupId>jakarta.xml.bind</groupId>
<artifactId>jakarta.xml.bind-api</artifactId>
<version>3.0.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>3.0.0</version>
<scope>runtime</scope>
</dependency>
Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*
, so update import statements:
javax.xml.bind -> jakarta.xml.bind
I had to get this working for contenteditable elements and jQuery and tought someone might want it ready to use:
$.fn.getCaret = function(n) {
var d = $(this)[0];
var s, r;
r = document.createRange();
r.selectNodeContents(d);
s = window.getSelection();
console.log('position: '+s.anchorOffset+' of '+s.anchorNode.textContent.length);
return s.anchorOffset;
};
$.fn.setCaret = function(n) {
var d = $(this)[0];
d.focus();
var r = document.createRange();
var s = window.getSelection();
r.setStart(d.childNodes[0], n);
r.collapse(true);
s.removeAllRanges();
s.addRange(r);
console.log('position: '+s.anchorOffset+' of '+s.anchorNode.textContent.length);
return this;
};
Usage $(selector).getCaret()
returns the number offset and $(selector).setCaret(num)
establishes the offeset and sets focus on element.
Also a small tip, if you run $(selector).setCaret(num)
from console it will return the console.log but you won't visualize the focus since it is established at the console window.
Bests ;D
Apparently the correct form is without the ""
As in

With eager evaluation, variables essentially turn into their values any time you look at them (to paraphrase). That said, Python does have built-in namespaces. For example, locals() will return a dictionary mapping a function's variables' names to their values, and globals() does the same for a module. Thus:
for name, value in globals().items():
if value is unknown_variable:
... do something with name
Note that you don't need to import anything to be able to access locals() and globals().
Also, if there are multiple aliases for a value, iterating through a namespace only finds the first one.

This is the notorious floating point rounding issue. Just add a very small number, to correct the issue.
double a;
a=3669.0;
int b;
b=a+ 1e-9;
Drop root privileges after you bind to port 80 (or 443).
This allows port 80/443 to remain protected, while still preventing you from serving requests as root:
function drop_root() {
process.setgid('nobody');
process.setuid('nobody');
}
A full working example using the above function:
var process = require('process');
var http = require('http');
var server = http.createServer(function(req, res) {
res.write("Success!");
res.end();
});
server.listen(80, null, null, function() {
console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
drop_root();
console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
});

Here, if you want to control it through HTML: do like below Option 1:
<meta http-equiv="expires" content="Sun, 01 Jan 2014 00:00:00 GMT"/>
<meta http-equiv="pragma" content="no-cache" />
And if you want to control it through PHP: do it like below Option 2:
header('Expires: Sun, 01 Jan 2014 00:00:00 GMT');
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Cache-Control: post-check=0, pre-check=0', FALSE);
header('Pragma: no-cache');
AND Option 2 IS ALWAYS BETTER in order to avoid proxy based caching issue.
IsNullOrWhiteSpace
is a convenience method that is similar to the following code, except that it offers superior performance:return String.IsNullOrEmpty(value) || value.Trim().Length == 0;
White-space characters are defined by the Unicode standard. The
IsNullOrWhiteSpace
method interprets any character that returns a value of true when it is passed to theChar.IsWhiteSpace
method as a white-space character.
There's no need for hacks or overflow. There's a pseudo-element for the dropdown arrow on IE:
select::-ms-expand {
display: none;
}
Moonrise is the best dark theme I have ever seen for Eclipse!

The correct syntax is:
import sampleModule = require('modulename');
or
import * as sampleModule from 'modulename';
Then compile your TypeScript with --module commonjs
.
If the package doesn't come with an index.d.ts
file and its package.json
doesn't have a "typings"
property, tsc
will bark that it doesn't know what 'modulename'
refers to. For this purpose you need to find a .d.ts
file for it on http://definitelytyped.org/, or write one yourself.
If you are writing code for Node.js you will also want the node.d.ts
file from http://definitelytyped.org/.
LPCWSTR
is equivalent to wchar_t const *
. It's a pointer to a wide character string that won't be modified by the function call.
You can assign to LPCWSTR
s by prepending a L to a string literal: LPCWSTR *myStr = L"Hello World";
LPCTSTR and any other T types, take a string type depending on the Unicode settings for your project. If _UNICODE
is defined for your project, the use of T types is the same as the wide character forms, otherwise the Ansi forms. The appropriate function will also be called this way: FindWindowEx
is defined as FindWindowExA
or FindWindowExW
depending on this definition.
but as for this method, I don't understand the purpose of Integer.MAX_VALUE and Integer.MIN_VALUE.
By starting out with smallest
set to Integer.MAX_VALUE
and largest
set to Integer.MIN_VALUE
, they don't have to worry later about the special case where smallest
and largest
don't have a value yet. If the data I'm looking through has a 10
as the first value, then numbers[i]<smallest
will be true (because 10
is <
Integer.MAX_VALUE
) and we'll update smallest
to be 10
. Similarly, numbers[i]>largest
will be true
because 10
is >
Integer.MIN_VALUE
and we'll update largest
. And so on.
Of course, when doing this, you must ensure that you have at least one value in the data you're looking at. Otherwise, you end up with apocryphal numbers in smallest
and largest
.
Note the point Onome Sotu makes in the comments:
...if the first item in the array is larger than the rest, then the largest item will always be Integer.MIN_VALUE because of the else-if statement.
Which is true; here's a simpler example demonstrating the problem (live copy):
public class Example
{
public static void main(String[] args) throws Exception {
int[] values = {5, 1, 2};
int smallest = Integer.MAX_VALUE;
int largest = Integer.MIN_VALUE;
for (int value : values) {
if (value < smallest) {
smallest = value;
} else if (value > largest) {
largest = value;
}
}
System.out.println(smallest + ", " + largest); // 1, 2 -- WRONG
}
}
To fix it, either:
Don't use else
, or
Start with smallest
and largest
equal to the first element, and then loop the remaining elements, keeping the else if
.
Here's an example of that second one (live copy):
public class Example
{
public static void main(String[] args) throws Exception {
int[] values = {5, 1, 2};
int smallest = values[0];
int largest = values[0];
for (int n = 1; n < values.length; ++n) {
int value = values[n];
if (value < smallest) {
smallest = value;
} else if (value > largest) {
largest = value;
}
}
System.out.println(smallest + ", " + largest); // 1, 5
}
}

Make's substitutions feature is nice and helped me to write
%.i: src/%.c $(INCLUDE)
gcc -E $(CPPFLAGS) $(INCLUDE:%=-I %) $< > $@
You might find this useful, because it asks make
to check for changes in include folders too
This code work correctly only when u put into button click because at that time user put values into editable text and then when user clicks button it fetch the data and convert into string
EditText dob=(EditText)findviewbyid(R.id.edit_id);
String str=dob.getText().toString();
Dim
and Private
work the same, though the common convention is to use Private
at the module level, and Dim
at the Sub/Function level. Public
and Global
are nearly identical in their function, however Global
can only be used in standard modules, whereas Public
can be used in all contexts (modules, classes, controls, forms etc.) Global
comes from older versions of VB and was likely kept for backwards compatibility, but has been wholly superseded by Public
.
Adding to Matt's answer above (as I don't have comment privileges yet), one mouse-free workflow would be:
Esc
then m
then Enter
so that you gain focus again and can start typing.
Without the last Enter
you would still be in Escape mode and would otherwise have to use your mouse to activate text input in the cell.
Another way would be to add a new cell, type out your markdown in "Code" mode and then change to markdown once you're done typing everything you need, thus obviating the need to refocus.
You can then move on to your next cells. :)
I think of it as a large array of binary data. The usability of BLOB follows immediately from the limited bandwidth of the DB interface, it is not determined by the DB storage mechanisms. No matter how you store the large piece of data, the only way to store and retrieve is the narrow database interface. The database is a bottleneck of the system. Why to use it as a file server, which can easily be distributed? Normally you do not want to download the BLOB. You just want the DB to store your BLOB urls. Deposite the BLOBs on a separate file server. Then, you reliefe the precious DB connection and provide unlimited bandwidth for large objects. This creates some issue of coherence though.
If you need a drive letter (some applications don't like UNC style paths that start with a machine-name) you can "map a drive" to a UNC path. Right-click on "My Computer" and select Map Network Drive... or use this command line:
NET USE z: \server\c$\folder1\folder2
NET USE y: \server\d$
Note that you can map drive-to-drive or drill down and map to sub-folder.
For the iterative algorithm, however, we have:
int iterativeEGCD(long long n, long long m) {
long long a;
int numberOfIterations = 0;
while ( n != 0 ) {
a = m;
m = n;
n = a % n;
numberOfIterations ++;
}
printf("\nIterative GCD iterated %d times.", numberOfIterations);
return m;
}
With Fibonacci pairs, there is no difference between iterativeEGCD()
and iterativeEGCDForWorstCase()
where the latter looks like the following:
int iterativeEGCDForWorstCase(long long n, long long m) {
long long a;
int numberOfIterations = 0;
while ( n != 0 ) {
a = m;
m = n;
n = a - n;
numberOfIterations ++;
}
printf("\nIterative GCD iterated %d times.", numberOfIterations);
return m;
}
Yes, with Fibonacci Pairs, n = a % n
and n = a - n
, it is exactly the same thing.
We also know that, in an earlier response for the same question, there is a prevailing decreasing factor: factor = m / (n % m)
.
Therefore, to shape the iterative version of the Euclidean GCD in a defined form, we may depict as a "simulator" like this:
void iterativeGCDSimulator(long long x, long long y) {
long long i;
double factor = x / (double)(x % y);
int numberOfIterations = 0;
for ( i = x * y ; i >= 1 ; i = i / factor) {
numberOfIterations ++;
}
printf("\nIterative GCD Simulator iterated %d times.", numberOfIterations);
}
Based on the work (last slide) of Dr. Jauhar Ali, the loop above is logarithmic.
Yes, small Oh because the simulator tells the number of iterations at most. Non Fibonacci pairs would take a lesser number of iterations than Fibonacci, when probed on Euclidean GCD.
For BFS, we can consider Facebook example. We receive suggestion to add friends from the FB profile from other other friends profile. Suppose A->B, while B->E and B->F, so A will get suggestion for E And F. They must be using BFS to read till second level. DFS is more based on scenarios where we want to forecast something based on data we have from source to destination. As mentioned already about chess or sudoku. Once thing I have different here is, I believe DFS should be used for shortest path because DFS will cover the whole path first then we can decide the best. But as BFS will use greedy's approach so might be it looks like its the shortest path, but the final result might differ. Let me know whether my understanding is wrong.
For what it's worth, The Ruby docs are an amazing resource for these kinds of questions.
I would also take note of the length of the array you're searching through. The include?
method will run a linear search with O(n) complexity which can get pretty ugly depending on the size of the array.
If you're working with a large (sorted) array, I would consider writing a binary search algorithm which shouldn't be too difficult and has a worst case of O(log n).
Or if you're using Ruby 2.0, you can take advantage of bsearch
.
int[] arr1 = { 1, 2, 3, 4, 5 };
int[] product = new int[arr1.Length];
for (int i = 0; i < arr1.Length; i++)
{
for (int j = 0; j < product.Length; j++)
{
if (i != j)
{
product[j] = product[j] == 0 ? arr1[i] : product[j] * arr1[i];
}
}
}
There is the dir(theobject)
method to list all the fields and methods of your object (as a tuple) and the inspect module (as codeape write) to list the fields and methods with their doc (in """).
Because everything (even fields) might be called in Python, I'm not sure there is a built-in function to list only methods. You might want to try if the object you get through dir
is callable or not.
Expanding on Vikram's answer, if you are coloring dynamic views, like recycler view items, etc.... Then you probably want to call mutate() before you set the color. If you don't do this, any views that have a common drawable (i.e a background) will also have their drawable changed/colored.
public static void setBackgroundColorAndRetainShape(final int color, final Drawable background) {
if (background instanceof ShapeDrawable) {
((ShapeDrawable) background.mutate()).getPaint().setColor(color);
} else if (background instanceof GradientDrawable) {
((GradientDrawable) background.mutate()).setColor(color);
} else if (background instanceof ColorDrawable) {
((ColorDrawable) background.mutate()).setColor(color);
}else{
Log.w(TAG,"Not a valid background type");
}
}
There is a simple way:
Android:
String macAddress =
android.provider.Settings.Secure.getString(this.getApplicationContext().getContentResolver(), "android_id");
Xamarin:
Settings.Secure.GetString(this.ContentResolver, "android_id");
public String convertImageToBase64(String filePath) {
byte[] fileContent = new byte[0];
String base64encoded = null;
try {
fileContent = FileUtils.readFileToByteArray(new File(filePath));
} catch (IOException e) {
log.error("Error reading file: {}", filePath);
}
try {
base64encoded = Base64.getEncoder().encodeToString(fileContent);
} catch (Exception e) {
log.error("Error encoding the image to base64", e);
}
return base64encoded;
}
I found that I had the same problem when I was running a project and debugging by attaching to an IIS process. I also was running in Debug mode with optimizations turned off. While I thought the code compiled fine, when I detached and tried to compile, one of the references was not found. This was due to another developer here that made modifications and changed the location of the reference. The reference did not show up with the alert symbol, so I thought everything was fine until I did the compilation. Once fixing the reference and running again it worked.
If you use apache tomcat 8.0 version, instead of it, use tomcat 7.0 I had tried localhost to 127.0.0.1 and power off firewall but not working, but use tomcat 7.0 and now working
The best explanation I could get is from Tamas Piro's post.
TLDR; TypeScript uses the DOM typings for the global execution environment. In your case there is a 'co' property on the global window object.
To solve this:
- Rename the variable, or
- Use TypeScript modules, and add an empty export{}:
export {};
or
- Configure your compiler options by not adding DOM typings:
Edit tsconfig.json in the TypeScript project directory.
{
"compilerOptions": {
"lib": ["es6"]
}
}
Here's a different example that can't be rewritten without aliases ( can't GROUP BY DISTINCT
).
Imagine a table called purchases
that records purchases made by customers
at stores
, i.e. it's a many to many table and the software needs to know which customers have made purchases at more than one store:
SELECT DISTINCT customer_id, SUM(1)
FROM ( SELECT DISTINCT customer_id, store_id FROM purchases)
GROUP BY customer_id HAVING 1 < SUM(1);
..will break with the error Every derived table must have its own alias
. To fix:
SELECT DISTINCT customer_id, SUM(1)
FROM ( SELECT DISTINCT customer_id, store_id FROM purchases) AS custom
GROUP BY customer_id HAVING 1 < SUM(1);
( Note the AS custom
alias).
You can remove the time component when comparing:
SELECT *
FROM sales
WHERE CONVERT(DATETIME, FLOOR(CONVERT(FLOAT, salesDate))) = '11/11/2010'
Another approach is to change the select to cover all the time between the start and end of the date:
SELECT *
FROM sales
-- WHERE salesDate BETWEEN '11/11/2010 00:00:00.00' AND '11/11/2010 23:59:59.999'
WHERE salesDate BETWEEN '2020-05-18T00:00:00.00' AND '2020-05-18T23:59:59.999'

I had the same problem, and in my case, the solution was updating the usb-serial driver using windows update on windows 10 device's manager. There was no need to download a especific driver, I just let windows update find a suitable driver.
You should not rely on instruments -s
. The officially supported tool for working with Simulators from the command line is xcrun simctl
.
The log directory for a device can be found with xcrun simctl getenv booted SIMULATOR_LOG_ROOT
. This will always be correct even if the location changes.
Now that things are moving to os_log
it is easier to open Console.app on the host Mac. Booted simulators should show up as a log source on the left, just like physical devices. You can also run log commands in the booted simulator:
# os_log equivalent of tail -f
xcrun simctl spawn booted log stream --level=debug
# filter log output
xcrun simctl spawn booted log stream --predicate 'processImagePath endswith "myapp"'
xcrun simctl spawn booted log stream --predicate 'eventMessage contains "error" and messageType == info'
# a log dump that Console.app can open
xcrun simctl spawn booted log collect
# open location where log collect will write the dump
cd `xcrun simctl getenv booted SIMULATOR_SHARED_RESOURCES_DIRECTORY`
If you want to use Safari Developer tools (including the JS console) with a webpage in the Simulator: Start one of the simulators, open Safari, then go to Safari on your mac and you should see Simulator in the menu.
You can open a URL in the Simulator by dragging it from the Safari address bar and dropping on the Simulator window. You can also use xcrun simctl openurl booted <url>
.
Now we can easily do this using the aspect-ratio
ref property
.container {
display: grid;
grid-template-columns: repeat(3, minmax(0, 1fr)); /* 3 columns */
grid-gap: 10px;
}
.container>* {
aspect-ratio: 1 / 1; /* a square ratio */
border: 1px solid;
/* center content */
display: flex;
align-items: center;
justify-content: center;
text-align: center;
}
img {
max-width: 100%;
display: block;
}
_x000D_
<div class="container">
<div> some content here </div>
<div><img src="https://picsum.photos/id/25/400/400"></div>
<div>

</div>
<div>more and more content <br>here</div>
<div>
<h2>another title</h2>
</div>
<div><img src="https://picsum.photos/id/104/400/400"></div>
</div>
_x000D_
Also like below where we can have a variable number of columns
.container {
display: grid;
grid-template-columns: repeat(auto-fill, minmax(250px, 1fr));
grid-gap: 10px;
}
.container>* {
aspect-ratio: 1 / 1; /* a square ratio */
border: 1px solid;
/* center content */
display: flex;
align-items: center;
justify-content: center;
text-align: center;

max-width: 100%;
display: block;

Splice is good, everyone explain splice so I didn't explain it. You can also use delete keyword in JavaScript, it's good. You can use $.grep also to manipulate this using jQuery.
The jQuery Way :
data.items = jQuery.grep(
data.items,
function (item,index) {
return item.id != "1";
});
DELETE Way:
delete data.items[0]
For Adding PUSH is better the splice, because splice is heavy weighted function. Splice create a new array , if you have a huge size of array then it may be troublesome. delete is sometime useful, after delete if you look for the length of the array then there is no change in length there. So use it wisely.
lets say you want to install scipy,
Here is the code to install it
!pip install scipy
Try this
in view:
<form name="formName" ng-submit="submitForm(formName)">
<!-- fields -->
</form>
in controller:
$scope.submitForm = function(form){
if(form.$valid) {
// Code here if valid
}
};
or
in view:
<form name="formName" ng-submit="submitForm(formName.$valid)">
<!-- fields -->
</form>
in controller:
$scope.submitForm = function(formValid){
if(formValid) {
// Code here if valid
}
};
I think another option is to open workspace in RStudio and then change list to grid at the top right of the environment(image below). Then tick the objects you want to clear and finally click on clear.
You can do this alike here but with your package. In my case, it was lsb_release
Run: yum whatprovides lsb_release
Response:

The package name SHOULD be without number and system type so yum packager can choose what is best for him.
The getRequestURL()
omits the port when it is 80 while the scheme is http
, or when it is 443 while the scheme is https
.
So, just use getRequestURL()
if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:
StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();
I use "xor" (it seems it's a keyword; in Code::Blocks at least it gets bold) just as you can use "and" instead of &&
and "or" instead of ||
.
if (first xor second)...
Yes, it is bitwise. Sorry.
Taken from this page:
"NaN" stands for "not a number". "Nan" is produced if a floating point operation has some input parameters that cause the operation to produce some undefined result. For example, 0.0 divided by 0.0 is arithmetically undefined. Taking the square root of a negative number is also undefined.
@RequestMapping(value="/register",method=RequestMethod.POST)
public ModelAndView postRegisterPage(HttpServletRequest request,HttpServletResponse response,
@ModelAttribute("bean")RegisterModel bean)
{
RegisterService service = new RegisterService();
boolean b = service.saveUser(bean);
if(b)
{
return new ModelAndView("registerPage","errorMessage","Registered Successfully!");
}
else
{
return new ModelAndView("registerPage","errorMessage","ERROR!!");
}
}
/* "registerPage" is the .jsp page -> which will viewed.
/* "errorMessage" is the variable that could be displayed in page using -> **${errorMessage}**
/* "Registered Successfully!" or "ERROR!!" is the message will be printed based on **if-else condition**
You can use TryParse to determine if the string can be parsed into an integer.
int i;
bool bNum = int.TryParse(str, out i);
The boolean will tell you if it worked or not.

You can simply check whether the multisets with the elements of x and y are equal:
import collections
collections.Counter(x) == collections.Counter(y)
This requires the elements to be hashable; runtime will be in O(n)
, where n
is the size of the lists.
If the elements are also unique, you can also convert to sets (same asymptotic runtime, may be a little bit faster in practice):
set(x) == set(y)
If the elements are not hashable, but sortable, another alternative (runtime in O(n log n)
) is
sorted(x) == sorted(y)
If the elements are neither hashable nor sortable you can use the following helper function. Note that it will be quite slow (O(n²)
) and should generally not be used outside of the esoteric case of unhashable and unsortable elements.
def equal_ignore_order(a, b):
""" Use only when elements are neither hashable nor sortable! """
unmatched = list(b)
for element in a:
try:
unmatched.remove(element)
except ValueError:
return False
return not unmatched
Once you have removed your duplicate(s):
ALTER TABLE dbo.yourtablename
ADD CONSTRAINT uq_yourtablename UNIQUE(column1, column2);
or
CREATE UNIQUE INDEX uq_yourtablename
ON dbo.yourtablename(column1, column2);
Of course, it can often be better to check for this violation first, before just letting SQL Server try to insert the row and returning an exception (exceptions are expensive).
http://www.sqlperformance.com/2012/08/t-sql-queries/error-handling
If you want to prevent exceptions from bubbling up to the application, without making changes to the application, you can use an INSTEAD OF
trigger:
CREATE TRIGGER dbo.BlockDuplicatesYourTable
ON dbo.YourTable
INSTEAD OF INSERT
AS
BEGIN
SET NOCOUNT ON;
IF NOT EXISTS (SELECT 1 FROM inserted AS i
INNER JOIN dbo.YourTable AS t
ON i.column1 = t.column1
AND i.column2 = t.column2
)
BEGIN
INSERT dbo.YourTable(column1, column2, ...)
SELECT column1, column2, ... FROM inserted;
END
ELSE
BEGIN
PRINT 'Did nothing.';
END
END
GO
But if you don't tell the user they didn't perform the insert, they're going to wonder why the data isn't there and no exception was reported.
EDIT here is an example that does exactly what you're asking for, even using the same names as your question, and proves it. You should try it out before assuming the above ideas only treat one column or the other as opposed to the combination...
USE tempdb;
GO
CREATE TABLE dbo.Person
(
ID INT IDENTITY(1,1) PRIMARY KEY,
Name NVARCHAR(32),
Active BIT,
PersonNumber INT
);
GO
ALTER TABLE dbo.Person
ADD CONSTRAINT uq_Person UNIQUE(PersonNumber, Active);
GO
-- succeeds:
INSERT dbo.Person(Name, Active, PersonNumber)
VALUES(N'foo', 1, 22);
GO
-- succeeds:

VALUES(N'foo', 0, 22);
GO
-- fails:
INSERT dbo.Person(Name, Active, PersonNumber)
VALUES(N'foo', 1, 22);
GO
Data in the table after all of this:
ID Name Active PersonNumber
---- ------ ------ ------------
1 foo 1 22
2 foo 0 22
Error message on the last insert:

Note that, in addition to number of predictive variables, the Adjusted R-squared formula above also adjusts for sample size. A small sample will give a deceptively large R-squared.
Ping Yin & Xitao Fan, J. of Experimental Education 69(2): 203-224, "Estimating R-squared shrinkage in multiple regression", compares different methods for adjusting r-squared and concludes that the commonly-used ones quoted above are not good. They recommend the Olkin & Pratt formula.
However, I've seen some indication that population size has a much larger effect than any of these formulas indicate. I am not convinced that any of these formulas are good enough to allow you to compare regressions done with very different sample sizes (e.g., 2,000 vs. 200,000 samples; the standard formulas would make almost no sample-size-based adjustment). I would do some cross-validation to check the r-squared on each sample.
When you do len(df['column name'])
you are just getting one number, namely the number of rows in the DataFrame (i.e., the length of the column itself). If you want to apply len
to each element in the column, use df['column name'].map(len)
. So try
df[df['column name'].map(len) < 2]

This is how you make Android Google Maps API v2 work on your emulator.
Create a new emulator
these are the settings that are working for me. I don't know for different ones.
Start the emulator
install com.android.vending-1.apk and com.google.android.gms-1.apk via ADB install command

If you're willing and able to employ a little jquery, you can simply do this:
$('.someDiv').css([".radius", ".opacity"]);
If you have a javascript that already processes the page or you can enclose it somewhere in <script> tags. If so, wrap the above in the document ready function:
$(document).ready( function() {
$('.someDiv').css([".radius", ".opacity"]);
}
I recently came across this while updating a wordpress plugin. The them has been changed which used a lot of "!important" directives across the css. I had to use jquery to force my styles because of the genius decision to declare !important on several tags.
try this

<TextView
android:id="@+id/xxx"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"

Every time you add a new element to the List you need to re-bind your Grid. Something like:
List<Person> persons = new List<Person>();
persons.Add(new Person() { Name = "Joe", Surname = "Black" });
persons.Add(new Person() { Name = "Misha", Surname = "Kozlov" });
dataGridView1.DataSource = persons;
// added a new item
persons.Add(new Person() { Name = "John", Surname = "Doe" });
// bind to the updated source
dataGridView1.DataSource = persons;
You already got the right answer, but if you dislike the UIColor
interface like me, you can do this:
#import "UIColor+Helper.h"
// ...
myLabel.textColor = [UIColor colorWithRGBA:0xA06105FF];
UIColor+Helper.h:
#import <UIKit/UIKit.h>
@interface UIColor (Helper)
+ (UIColor *)colorWithRGBA:(NSUInteger)color;
@end
UIColor+Helper.m:
#import "UIColor+Helper.h"
@implementation UIColor (Helper)
+ (UIColor *)colorWithRGBA:(NSUInteger)color
{
return [UIColor colorWithRed:((color >> 24) & 0xFF) / 255.0f
green:((color >> 16) & 0xFF) / 255.0f
blue:((color >> 8) & 0xFF) / 255.0f
alpha:((color) & 0xFF) / 255.0f];
}
@end
You can add command line arguments to your run configuration. Just edit the run configuration and add -Dmyprop=value (or whatever) to the VM Arguments Box.
In general, you use the #
syntax:
{{#a_boolean}}
I only show up if the boolean was true.
{{/a_boolean}}
The goal is to move as much logic as possible out of the template (which makes sense).
The issue pointed in the comment is valid, so here is a different revision that's immune to that:
function show_alert() {
if(!confirm("Do you really want to do this?")) {
return false;
}
this.form.submit();
}
I'm using bootstrap 4, you can use outline and box-shadow.
#buttonId {
box-shadow: none;
outline: none;
}
Or if the button is inside an element like a div without back-ground, box-shadow is enough.
#buttonId {
box-shadow: none;
}
For the former, convention over configuration. Rails default when you reference another table with
belongs_to :something
is to look for something_id
.
references
, or belongs_to
is actually newer way of writing the former with few quirks.
Important is to remember that it will not create foreign keys for you. In order to do that, you need to set it up explicitly using either:
t.references :something, foreign_key: true
t.belongs_to :something_else, foreign_key: true
or (note the plural):
add_foreign_key :table_name, :somethings
add_foreign_key :table_name, :something_elses`
This should work:
/^((?!PART).)*$/
If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:
/^(?!PART)/
The (?!...)
syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/
." The site I've linked explains this far better than I can, but I'll try to break this down:
^ #Start matching from the beginning of the string.
(?!PART) #This position must not be followed by the string "PART".
. #Matches any character except line breaks (it will include those in single-line mode).
$ #Match all the way until the end of the string.
The ((?!xxx).)*
idiom is probably hardest to understand. As we saw, (?!PART)
looks at the string ahead and says that whatever comes next can't match the subpattern /PART/
. So what we're doing with ((?!xxx).)*
is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.
The ^
and $
anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.
Since we do have ^
and $
, if PART were anywhere in the string, one of the characters would match (?=PART).
and the overall match would fail. Hope that's clear enough to be helpful.
The main point of the differences as pointed out @BizApps is that Load event happens right after the ViewState is populated while PreRender event happens later, right before Rendering phase, and after all individual children controls' action event handlers are already executing. Therefore, any modifications done by the controls' actions event handler should be updated in the control hierarchy during PreRender as it happens after.
The [new-ish at the time of writing in 2017] Fetch API is intended to make GET requests easy, but it is able to POST as well.
let data = {element: "barium"};
fetch("/post/data/here", {
method: "POST",
body: JSON.stringify(data)
}).then(res => {
console.log("Request complete! response:", res);
});
If you are as lazy as me (or just prefer a shortcut/helper):
window.post = function(url, data) {
return fetch(url, {method: "POST", body: JSON.stringify(data)});
}
// ...
post("post/data/here", {element: "osmium"});
UNSIGNED
only stores positive numbers (or zero). On the other hand, signed can store negative numbers (i.e., may have a negative sign).
Here's a table of the ranges of values each INTEGER
type can store:
Source: http://dev.mysql.com/doc/refman/5.6/en/integer-types.html
UNSIGNED
ranges from 0
to n
, while signed ranges from about -n/2
to n/2
.
In this case, you have an AUTO_INCREMENT
ID column, so you would not have negatives. Thus, use UNSIGNED
. If you do not use UNSIGNED
for the AUTO_INCREMENT
column, your maximum possible value will be half as high (and the negative half of the value range would go unused).
jQuery 'fixes up' events to account for browser differences. When it does so, you can always access the 'native' event with event.originalEvent
(see the Special Properties subheading on this page).
As mark.ribau said, it seems that there is no way to clear the Text widget in idle. One should edit the EditorWindow.py
module and add a method and a menu item in the EditorWindow class that does something like:
self.text.tag_remove("sel", "1.0", "end")
self.text.delete("1.0", "end")
and perhaps some more tag management of which I'm unaware of.

You can use Arrays.copyOf()
with a little reflection to make a nice helper function.
public class ArrayHelper {
public static <T> T[] push(T[] arr, T item) {
T[] tmp = Arrays.copyOf(arr, arr.length + 1);
tmp[tmp.length - 1] = item;
return tmp;
}
public static <T> T[] pop(T[] arr) {
T[] tmp = Arrays.copyOf(arr, arr.length - 1);
return tmp;
}
}
Usage:
String[] items = new String[]{"a", "b", "c"};
items = ArrayHelper.push(items, "d");
items = ArrayHelper.push(items, "e");
items = ArrayHelper.pop(items);
Results
Original: a,b,c
Array after push calls: a,b,c,d,e
Array after pop call: a,b,c,d
You can use the csv
module to parse tab seperated value files easily.
import csv
with open("tab-separated-values") as tsv:
for line in csv.reader(tsv, dialect="excel-tab"): #You can also use delimiter="\t" rather than giving a dialect.
...
Where line
is a list of the values on the current row for each iteration.
Edit: As suggested below, if you want to read by column, and not by row, then the best thing to do is use the zip()
builtin:
with open("tab-separated-values") as tsv:
for column in zip(*[line for line in csv.reader(tsv, dialect="excel-tab")]):

I was trying to install it in kubuntu 18.04, and i was already sure that i had java installed, I confirmed by trying

Since I already know that my java PATH variables are defined in /etc/environment file, I added that file to the top of /etc/init.d/jenkins file
source /etc/environment
you can even remove the PATH from /etc/init.d/jenkins file, since it's already defined in /etc/environment
after that, i restarted my jenkins server,and it seemed to start working fine from localhost:8080
Dougs answer is correct, but you actually can use $.getJSON
and catch errors (not having to use $.ajax
). Just chain the getJSON
call with a call to the fail
function:
$.getJSON('/foo/bar.json')
.done(function() { alert('request successful'); })
.fail(function() { alert('request failed'); });

This behavior is part of the jQuery.Deferred interface.
Basically it allows you to attach events to an asynchronous action after you call that action, which means you don't have to pass the event function to the action.
Read more about jQuery.Deferred here: http://api.jquery.com/category/deferred-object/
Or even shorter, with only standard modern Javascript:
var first_link = document.getElementsByTagName('a')[0];
first_link.dispatchEvent(new MouseEvent('click'));
The new MouseEvent
constructor takes a required event type name, then an optional object (at least in Chrome). So you could, for example, set some properties of the event:
first_link.dispatchEvent(new MouseEvent('click', {bubbles: true, cancelable: true}));
A simple solution without pandas:

The HTC devices have the PCSII.apk
which allow them to select usb connect mode. For your device, you can set it manually:
Use SQLite Editor to open /data/data/com.android.providers.setting/databases/settings.db
open table secure
turn settings starting with mount_ums_
to 0, then restart devices.
UPDATE: If it still doesn't work, try turning on debug mode.
As other answers have mentioned, NT (the kernel underlying modern versions of Windows) has an equivalent of Unix fork(). That's not the problem.
The problem is that cloning a process's entire state is not generally a sane thing to do. This is as true in the Unix world as it is in Windows, but in the Unix world, fork() is used all the time, and libraries are designed to deal with it. Windows libraries aren't.
For example, the system DLLs kernel32.dll and user32.dll maintain a private connection to the Win32 server process csrss.exe. After a fork, there are two processes on the client end of that connection, which is going to cause problems. The child process should inform csrss.exe of its existence and make a new connection – but there's no interface to do that, because these libraries weren't designed with fork() in mind.
So you have two choices. One is to forbid the use of kernel32 and user32 and other libraries that aren't designed to be forked – including any libraries that link directly or indirectly to kernel32 or user32, which is virtually all of them. This means that you can't interact with the Windows desktop at all, and are stuck in your own separate Unixy world. This is the approach taken by the various Unix subsystems for NT.
The other option is to resort to some sort of horrible hack to try to get unaware libraries to work with fork(). That's what Cygwin does. It creates a new process, lets it initialize (including registering itself with csrss.exe), then copies most of the dynamic state over from the old process and hopes for the best. It amazes me that this ever works. It certainly doesn't work reliably – even if it doesn't randomly fail due to an address space conflict, any library you're using may be silently left in a broken state. The claim of the current accepted answer that Cygwin has a "fully-featured fork()" is... dubious.
Summary: In an Interix-like environment, you can fork by calling fork(). Otherwise, please try to wean yourself from the desire to do it. Even if you're targeting Cygwin, don't use fork() unless you absolutely have to.
Try this code
$('window').scrollDown(function(){$(#div).hide()});
$('window').scrollUp(function(){ $(#div).show() });
It's possible with a lot of work.
Basically, you have to post likes action via the Open Graph API. Then, you can add a custom design to your like button.
But then, you''ll need to keep track yourself of the likes so a returning user will be able to unlike content he liked previously.
Plus, you'll need to ask user to log into your app and ask them the publish_action
permission.
All in all, if you're doing this for an application, it may worth it. For a website where you basically want user to like articles, then this is really to much.
Also, consider that you increase your drop-off rate each time you ask user a permission via a Facebook login.
If you want to see an example, I've recently made an app using the open graph like button, just hover on some photos in the mosaique to see it
I think this issue will help you. Standard deviation
You can easily try the https://help.github.com/enterprise/2.15/user/articles/splitting-a-subfolder-out-into-a-new-repository/
This worked for me. The issues i faced in the steps given above are
in this command git filter-branch --prune-empty --subdirectory-filter FOLDER-NAME BRANCH-NAME
The BRANCH-NAME
is master
if the last step fails when committing due to protection issue follow - https://docs.gitlab.com/ee/user/project/protected_branches.html
Why JSON RPC:
In case of REST APIs, we have to define a controller for each functionality/method we might need. As a result if we have 10 methods that we want accessible to a client, we have to write 10 controllers to interface the client's request to a particular method.
Another factor is, even though we have different controllers for each method/functionality, the client has to remember wether to use POST or GET. This complicates things further. On top of that to send data, one has to set the content type of the request if POST is used.
In case of JSON RPC, things are greatly simplified because most JSONRPC servers operate on POST HTTP methods and the content type is always application/json. This takes the load off of remembering to use proper HTTP method and content settings on client side.
One doesn't have to create separate controllers for different methods/functionalities the server wants to expose to a client.
Why REST:
You have separate URLs for different functionality the server wants to expose to client side. As a result, you can embed these urls.
Most of these points are debatable and completely depend upon the need of a person.
Simply it's work fine, in HTML:
<button type="button" id="btn_CommitAll"class="btn_CommitAll">save</button>
In JQuery side put this function for disable button:
function disableButton() {
$('.btn_CommitAll').prop("disabled", true);
}
For enable button:
function enableButton() {
$('.btn_CommitAll').prop("disabled", false);
}
That's all.
Javascript which runs on the client machine can't access the local disk file system due to security restrictions.
If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.
The following works for me:
Map<String, String> propertyMap = getJsonAsMap(json);
where getJsonAsMap
is defined like so:
public HashMap<String, String> getJsonAsMap(String json)
{
try
{
ObjectMapper mapper = new ObjectMapper();
TypeReference<Map<String,String>> typeRef = new TypeReference<Map<String,String>>() {};
HashMap<String, String> result = mapper.readValue(json, typeRef);
return result;
}
catch (Exception e)
{
throw new RuntimeException("Couldnt parse json:" + json, e);
}
}
Note that this will fail if you have child objects in your json (because they're not a String
, they're another HashMap
), but will work if your json is a key value list of properties like so:
{
"client_id": "my super id",
"exp": 1481918304,
"iat": "1450382274",
"url": "http://www.example.com"
}
If you only want to read the first 999,999 (non-header) rows:
read_csv(..., nrows=999999)
If you only want to read rows 1,000,000 ... 1,999,999
read_csv(..., skiprows=1000000, nrows=999999)
nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*
skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file
and for large files, you'll probably also want to use chunksize:
chunksize : int, default None Return TextFileReader object for iteration
From the Docker FAQ:
Docker is not a replacement for lxc. "lxc" refers to capabilities of the linux kernel (specifically namespaces and control groups) which allow sandboxing processes from one another, and controlling their resource allocations.
On top of this low-level foundation of kernel features, Docker offers a high-level tool with several powerful functionalities:
Portable deployment across machines. Docker defines a format for bundling an application and all its dependencies into a single object which can be transferred to any docker-enabled machine, and executed there with the guarantee that the execution environment exposed to the application will be the same. Lxc implements process sandboxing, which is an important pre-requisite for portable deployment, but that alone is not enough for portable deployment. If you sent me a copy of your application installed in a custom lxc configuration, it would almost certainly not run on my machine the way it does on yours, because it is tied to your machine's specific configuration: networking, storage, logging, distro, etc. Docker defines an abstraction for these machine-specific settings, so that the exact same docker container can run - unchanged - on many different machines, with many different configurations.
Application-centric. Docker is optimized for the deployment of applications, as opposed to machines. This is reflected in its API, user interface, design philosophy and documentation. By contrast, the lxc helper scripts focus on containers as lightweight machines - basically servers that boot faster and need less ram. We think there's more to containers than just that.
Automatic build. Docker includes a tool for developers to automatically assemble a container from their source code, with full control over application dependencies, build tools, packaging etc. They are free to use make, maven, chef, puppet, salt, debian packages, rpms, source tarballs, or any combination of the above, regardless of the configuration of the machines.
Versioning. Docker includes git-like capabilities for tracking successive versions of a container, inspecting the diff between versions, committing new versions, rolling back etc. The history also includes how a container was assembled and by whom, so you get full traceability from the production server all the way back to the upstream developer. Docker also implements incremental uploads and downloads, similar to "git pull", so new versions of a container can be transferred by only sending diffs.
Component re-use. Any container can be used as an "base image" to create more specialized components. This can be done manually or as part of an automated build. For example you can prepare the ideal python environment, and use it as a base for 10 different applications. Your ideal postgresql setup can be re-used for all your future projects. And so on.
Sharing. Docker has access to a public registry (https://registry.hub.docker.com/) where thousands of people have uploaded useful containers: anything from redis, couchdb, postgres to irc bouncers to rails app servers to hadoop to base images for various distros. The registry also includes an official "standard library" of useful containers maintained by the docker team. The registry itself is open-source, so anyone can deploy their own registry to store and transfer private containers, for internal server deployments for example.
Tool ecosystem. Docker defines an API for automating and customizing the creation and deployment of containers. There are a huge number of tools integrating with docker to extend its capabilities. PaaS-like deployment (Dokku, Deis, Flynn), multi-node orchestration (maestro, salt, mesos, openstack nova), management dashboards (docker-ui, openstack horizon, shipyard), configuration management (chef, puppet), continuous integration (jenkins, strider, travis), etc. Docker is rapidly establishing itself as the standard for container-based tooling.
I hope this helps!
Instead of using map
, I'd recommend using a generator expression with the capability of join
to accept an iterator:
def get_nice_string(list_or_iterator):
return "[" + ", ".join( str(x) for x in list_or_iterator) + "]"
Here, join
is a member function of the string class str
. It takes one argument: a list (or iterator) of strings, then returns a new string with all of the elements concatenated by, in this case, ,
.
Simple Solution, just type the below:
conda update pandas
Type this in your preferred shell (on Windows, use Anaconda Prompt as administrator).
Android Studio 1.3.1 has neither
Gradle > Global Gradle settings > Offline work
nor a
Compiler
menu. To access the compiler menu, go to :
File > Settings > Build, Execution & Deployment > Compiler > Compiler
and de-select Configure on demand
The above still uses data but is faster, I was able to load images and maps. However, in addition, if you want to be completely offline, you need to do the following:
File -> Settings ->Build, Execution,Deployment -> Build Tools -> Gradle ->
check Offline work
Click the OK
button.
For Android Studio 2.0 it is the same procedure.
There is only one user Location, so you can iterate List of nearby places can call the distanceTo()
function to get the distance, you can store in an array if you like.
From what I understand, distanceBetween()
is for far away places, it's output is a WGS84 ellipsoid.
substr($string, -1)
