The standard approach is to use the select module.
However, this doesn't work on Windows. For that, you can use the msvcrt module's keyboard polling.
Often, this is done with multiple threads -- one per device being "watched" plus the background processes that might need to be interrupted by the device.
Non-blocking: This function won't wait while on the stack.
Asynchronous: Work may continue on behalf of the function call after that call has left the stack
Insert a transparent gif 1px x 1px just inside the <body>
tag:
<body><img src="route-to-images/blim.gif" class="blimover">
Then style it with this:
.blimover {
width: 100% !important;
height: 100% !important;
z-index: 1000 !important;
position: absolute !important;
top: 0 !important;
left: 0 !important;
}
This will remove any click functionality from a page, but it sure stops people stealing any content!
You can apply the same to a <div>
, <section>
, <article>
etc, just name accordingly and prevent your copy and/or images being ripped.
Nothing stops a screengrab though ... ...
Just use child_process.execSync
and call the system's sleep function.
//import child_process module
const child_process = require("child_process");
// Sleep for 5 seconds
child_process.execSync("sleep 5");
// Sleep for 250 microseconds
child_process.execSync("usleep 250");
// Sleep for a variable number of microseconds
var numMicroSeconds = 250;
child_process.execFileSync("usleep", [numMicroSeconds]);
I use this in a loop at the top of my main application script to make Node wait until network drives are attached before running the rest of the application.
This is a combination of the answers by DougW, Good Guy Greg, and Paul. I found it was all needed when trying to use this with a custom listview adapter and non-standard list items otherwise the listview crashed the application (also crashed with the answer by Nex):
public void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
return;
}
int totalHeight = listView.getPaddingTop() + listView.getPaddingBottom();
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
if (listItem instanceof ViewGroup)
listItem.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
}
To expand on the top-voted answer, for reference, if the you want to add more complex items to the array:
@:myArray.push(ClassMember1: "@d.ClassMember1", ClassMember2: "@d.ClassMember2");
etc.
Furthermore, if you want to pass the array as a parameter to your controller, you can stringify it first:
myArray = JSON.stringify({ 'myArray': myArray });
I normally use both -- a datepicker that populates a textfield in the correct format. Advanced users can edit the textfield directly, mouse-happy users can pick using the datepicker.
If you're worried about space, I usually have just the textfield with a little calendar icon next to it. If you click on the calendar icon it brings up the datepicker as a popup.
Also I find it good practice to pre-populate the textfield with text that indicates the correct format (i.e.: "DD/MM/YYYY"). When the user focuses the textfield that text disappears so they can enter their own.
More modern syntax:
git diff ..master path/to/file
The double-dot prefix means "from the current working directory to". You can also say:
master..
, i.e. the reverse of above. This is the same as master
.mybranch..master
, explicitly referencing a state other than the current working tree.v2.0.1..master
, i.e. referencing a tag.[refspec]..[refspec]
, basically anything identifiable as a code state to git.try following to see all instances of python
whereis python

Then remove all instances using:
sudo apt autoremove python
repeat sudo apt autoremove python(for all versions) that should do it, then install Anaconda and manage Pythons however you like if you need to reinstall it.
No need to use expensive regex
, if barely needed then try-
Use r'(/)(?=$)'
pattern that is capture last /
and replace with r''
i.e. blank character.
>>>re.sub(r'(/)(?=$)',r'','/home/ro/A_Python_Scripts/flask-auto/myDirectory/scarlett Johanson/1448543562.17.jpg/')
>>>'/home/ro/A_Python_Scripts/flask-auto/myDirectory/scarlett Johanson/1448543562.17.jpg'
You can use \1
(refer to http://www.grymoire.com/Unix/Sed.html#uh-4):
echo "Hello is a String" | sed 's/Hello\(.*\)String/\1/g'
The contents that is inside the brackets will be stored as \1
.
\w
matches a word character. \b
is a zero-width match that matches a position character that has a word character on one side, and something that's not a word character on the other. (Examples of things that aren't word characters include whitespace, beginning and end of the string, etc.)
\w
matches a
, b
, c
, d
, e
, and f
in "abc def"
\b
matches the (zero-width) position before a
, after c
, before d
, and after f
in "abc def"
let's say you want a pointer to point at the address 0x28ff4402, the usual way is
uint32_t *ptr;
ptr = (uint32_t*) 0x28ff4402 //type-casting the address value to uint32_t pointer
*ptr |= (1<<13) | (1<<10); //access the address how ever you want
So the short way is to use a MACRO,
#define ptr *(uint32_t *) (0x28ff4402)
First clear the temporary files in Windows system, then restart your system.
Run > %temp%
> delete all files
You need to create toast on UI thread. Find the example below.
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(activity, "YOUR_MESSAGE", Toast.LENGTH_SHORT).show();
}
});
For displaying Toast message please refer to this article
One way is to associating unique properties with your file while creation.
properties = "{ \
key='somekey' and \
value='somevalue'
}"
then create a query.
query = "title = " + "\'" + title + "\'" + \
AND + "mimeType = " + "\'" + mimeType + "\'" + \
AND + "trashed = false" + \
AND + "properties has " + properties
All the file properties(title, etc) already known to you can go here + properties.
you have to check your pip package to be updated to the latest version in your pycharm and then install numpy package. in settings -> project:progLangComp -> Project Interpreter there is a table of packages and their current version (just labelled as Version) and their latest version (labelled as Latest). Pip current version number should be the same as latest version. If you see a blue arrow in front of pip, you have to update it to the latest then trying to install numpy or any other packages that you couldn't install, for me it was pandas which I wanted to install.
What are iml files in Android Studio project?
A Google search on iml file
turns up:
IML is a module file created by IntelliJ IDEA, an IDE used to develop Java applications. It stores information about a development module, which may be a Java, Plugin, Android, or Maven component; saves the module paths, dependencies, and other settings.
(from this page)
why not to use gradle scripts to integrate with external modules that you add to your project.
You do "use gradle scripts to integrate with external modules", or your own modules.
However, Gradle is not IntelliJ IDEA's native project model — that is separate, held in .iml
files and the metadata in .idea/
directories. In Android Studio, that stuff is largely generated out of the Gradle build scripts, which is why you are sometimes prompted to "sync project with Gradle files" when you change files like build.gradle
. This is also why you don't bother putting .iml
files or .idea/
in version control, as their contents will be regenerated.
If I have a team that work in different IDE's like Eclipse and AS how to make project IDE agnostic?
To a large extent, you can't.
You are welcome to have an Android project that uses the Eclipse-style directory structure (e.g., resources and manifest in the project root directory). You can teach Gradle, via build.gradle
, how to find files in that structure. However, other metadata (compileSdkVersion
, dependencies, etc.) will not be nearly as easily replicated.
Other alternatives include:
Move everybody over to another build system, like Maven, that is equally integrated (or not, depending upon your perspective) to both Eclipse and Android Studio
Hope that Andmore takes off soon, so that perhaps you can have an Eclipse IDE that can build Android projects from Gradle build scripts
Have everyone use one IDE
The XML declaration in the document map consists of the following:
The version number, ?xml version="1.0"?.
This is mandatory. Although the number might change for future versions of XML, 1.0 is the current version.
The encoding declaration,
encoding="UTF-8"?
This is optional. If used, the encoding declaration must appear immediately after the version information in the XML declaration, and must contain a value representing an existing character encoding.
My best advice is to look at your compiler's documentation, because pragmas are by definition implementation-specific. For instance, in embedded projects I've used them to locate code and data in different sections, or declare interrupt handlers. i.e.:
#pragma code BANK1
#pragma data BANK2
#pragma INT3 TimerHandler
Note to the above solution (from A Paul): The solution doesn't work, cause it doesn't reconstructs back a HashMap< String, Object > - instead it creates a HashMap< String, LinkedHashMap >.
Reason why is because during demarshalling, each Object (JSON marshalled as a LinkedHashMap) is used as-is, it takes 1-on-1 the LinkedHashMap (instead of converting the LinkedHashMap back to its proper Object).
If you had a HashMap< String, MyOwnObject > then proper demarshalling was possible - see following example:
ObjectMapper mapper = new ObjectMapper();
TypeFactory typeFactory = mapper.getTypeFactory();
MapType mapType = typeFactory.constructMapType(HashMap.class, String.class, MyOwnObject.class);
HashMap<String, MyOwnObject> map = mapper.readValue(new StringReader(hashTable.toString()), mapType);
You could do something like this:
grd.DataSource = getDataSource();
if (grd.ColumnCount > 1)
{
for (int i = 0; i < grd.ColumnCount-1; i++)
grd.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
grd.Columns[grd.ColumnCount-1].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
}
if (grd.ColumnCount==1)
grd.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
All columns will adapt to the content except the last one will fill the grid.
The method argument specifies the parameter of the smooth statistic. You can see stat_smooth
for the list of all possible arguments to the method argument.
You can use this Polyfill in ie and chrome
if (!('contains' in String.prototype)) {
String.prototype.contains = function (str, startIndex) {
"use strict";
return -1 !== String.prototype.indexOf.call(this, str, startIndex);
};
}
For links generated in a JSP with custom tags, I had to use
<%@ page session="false" %>
in the JSP
AND
request.getSession().invalidate();

You can indeed match all those characters, but it's safer to escape the -
so that it is clear that it be taken literally.
If you are using a POSIX variant you can opt to use:
([[:alnum:]\-_]+)
But a since you are including the underscore I would simply use:
([\w\-]+)
(works in all variants)
I was able to work it out only after adding those two TOGETHER:

One important function of the main
key is that it provides the path for your entry point. This is very helpful when working with nodemon
. If you work with nodemon
and you define the main
key in your package.json
as let say "main": "./src/server/app.js"
, then you can simply crank up the server with typing nodemon
in the CLI with root as pwd instead of nodemon ./src/server/app.js
.
I think I got the reason for the above error. It is the corporate proxy(virtual private network) provided in order to work in the client network. Without that connection I frequently faced the same problem be it maven build or npm install.

Accepted answer of Kapil is flawed, it will update more than one record if there are 2 or more than one records available with same timestamps, not a true top 1 query.
;With cte as (
SELECT TOP(1) email_fk FROM abc WHERE id= 177 ORDER BY created DESC

UPDATE cte SET email_fk = 10

Using ADO (AnonJr already explained) and utilizing SQL is possibly the best option for fetching data from a closed workbook without opening that in conventional way. Please watch this VIDEO.
OTHERWISE, possibly GetObject(<filename with path>)
is the most CONCISE way. Worksheets remain invisible, however will appear in project explorer window in VBE just like any other workbook opened in conventional ways.
Dim wb As Workbook
Set wb = GetObject("C:\MyData.xlsx") 'Worksheets will remain invisible, no new window appears in the screen
' your codes here
wb.Close SaveChanges:=False
If you want to read a particular sheet, need not even define a Workbook variable
Dim sh As Worksheet
Set sh = GetObject("C:\MyData.xlsx").Worksheets("MySheet")
' your codes here
sh.Parent.Close SaveChanges:=False 'Closes the associated workbook
Actually the ng-disabled directive works with the " || " logical operator for me. The " && " evaluate only one condition.
PEP 8 is good, the only thing that i wish it came down harder on was the Tabs-vs-Spaces holy war.
Basically if you are starting a project in python, you need to choose Tabs or Spaces and then shoot all offenders on sight.
This is very much implementation specific, but the general idea is to allow providers to issue short term access tokens with long term refresh tokens. Why?
In my case, I had a collection of radio buttons that needed to be in a group. I just included a 'Selected' property in the model. Then, in the loop to output the radiobuttons just do...
@Html.RadioButtonFor(m => Model.Selected, Model.Categories[i].Title)
This way, the name is the same for all radio buttons. When the form is posted, the 'Selected' property is equal to the category title (or id or whatever) and this can be used to update the binding on the relevant radiobutton, like this...
model.Categories.Find(m => m.Title.Equals(model.Selected)).Selected = true;
May not be the best way, but it does work.

Selected answer throws exceptions, and the answer from Carlos Toledo applies filtering after retrieving all values from the database.

It's possible that you've run out of memory or some space elsewhere and it prompted the system to mount an overflow filesystem, and for whatever reason, it's not going away.
Try unmounting the overflow partition:
umount /tmp
or
umount overflow
Many firewalls drop outbound connections which are not to ports 80 or 443 (http & https); some even drop connections to those ports that are not HTTP(S). FTP may or may not be allowed, not to speak of the active/PASV modes.
Also, HTTP/1.1 allows for much better partial requests ("only send from byte 123456 to the end of file"), conditional requests and caching ("only send if content changed/if last-modified-date changed") and content compression (gzip).
HTTP is much easier to use through a proxy.
From my anecdotal evidence, HTTP is easier to make work with dropped/slow/flaky connections; e.g. it is not needed to (re)establish a login session before (re)initiating transfer.
OTOH, HTTP is stateless, so you'd have to do authentication and building a trail of "who did what when" yourself.
The only difference in speed I've noticed is transferring lots of small files: HTTP with pipelining is faster (reduces round-trips, esp. noticeable on high-latency networks).
Note that HTTP/2 offers even more optimizations, whereas the FTP protocol has not seen any updates for decades (and even extensions to FTP have insignificant uptake by users). So, unless you are transferring files through a time machine, HTTP seems to have won.
(Tangentially: there are protocols that are better suited for file transfer, such as rsync
or BitTorrent, but those don't have as much mindshare, whereas HTTP is Everywhere™)
Excellent i got solution:
Just clearing (.m2) complete folder and starting a new maven project problem solved for me.
Note:: .m2 folder located in os installed disk only.
If you want the exact location, check in Eclipse:
Eclipse-->window-->preferences-->maven-->user settings
There local repository path is for .m2
Delete entire .m2 folder and restart your eclipse.
This works for me!

In Bjarne's words (The C++ Programming Language, 4th Edition, page 366):
Where termination is an acceptable response, an uncaught exception will achieve that because it turns into a call of terminate() (§13.5.2.5). Also, a
noexcept
specifier (§13.5.1.1) can make that desire explicit.Successful fault-tolerant systems are multilevel. Each level copes with as many errors as it can without getting too contorted and leaves the rest to higher levels. Exceptions support that view. Furthermore,
terminate()
supports this view by providing an escape if the exception-handling mechanism itself is corrupted or if it has been incompletely used, thus leaving exceptions uncaught. Similarly,noexcept
provides a simple escape for errors where trying to recover seems infeasible.double compute(double x) noexcept; { string s = "Courtney and Anya"; vector<double> tmp(10); // ... }
The vector constructor may fail to acquire memory for its ten doubles and throw a
std::bad_alloc
. In that case, the program terminates. It terminates unconditionally by invokingstd::terminate()
(§30.4.1.3). It does not invoke destructors from calling functions. It is implementation-defined whether destructors from scopes between thethrow
and thenoexcept
(e.g., for s in compute()) are invoked. The program is just about to terminate, so we should not depend on any object anyway. By adding anoexcept
specifier, we indicate that our code was not written to cope with a throw.
If you want to avoid blocking, which is only necessary for very large loops, then wrap the contents of your loop in a function called like this: process.nextTick(function(){<contents of loop>})
, which will defer execution until the next tick, giving an opportunity for pending calls from other asynchronous functions to be processed.
In case you want to use sorted()
function: sorted(list1, key=int)
It returns a new sorted list.

HTML, CSS, JS are all good as given in above answers. However they won't stop user from clicking the loader and visiting page. And if page time is large, it looks broken and defeats the purpose.
So in CSS consider adding
pointer-events: none;
cursor: default;
Also, instead of using gif files, if you are using fontawesome which everybody uses now a days, consider using in your html

To get started , just to view something in Recycler view
recycler view adapter can be something like this.
class CustomAdapter: RecyclerView.Adapter<CustomAdapter.ViewHolder>() {
var data = listOf<String>()
set(value) {
field = value
notifyDataSetChanged()
}
override fun getItemCount() =data.size
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
holder.txt.text= data[position]
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
return ViewHolder(
LayoutInflater.from(parent.context).inflate(R.layout.item_view, parent, false)
)
}
class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView){
val txt: TextView = itemView.findViewById(R.id.item_text_view)
}
}
and to attach the adapter to the recycler view and to attach data to adapter
val view = findViewById<RecyclerView>(R.id.recycler_view)
val adapter = CustomAdapter()
val data = listOf("text1", "text2", "text3")
adapter.data = data
view.layoutManager = LinearLayoutManager(this, RecyclerView.VERTICAL, false)
view.adapter = adapter
Try this
data to load:
<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 4 5'><path fill='#343a40' d='M2 0L0 2h4zm0 5L0 3h4z'/></svg>
get a utf8 to base64 convertor and convert the "svg" string to:

var states = [,];
states[0,0] = tName;
states[0,1] = '1';

states[n,1] = '1';
Vector
is a broken class that is not threadsafe, despite it being "synchronized" and is only used by students and other inexperienced programmers.
ArrayList
is the go-to List implementation used by professionals and experienced programmers.
Professionals wanting a threadsafe List implementation use a CopyOnWriteArrayList
.
The syntax a if b else c
is a ternary operator in Python that evaluates to a
if the condition b
is true - otherwise, it evaluates to c
. It can be used in comprehension statements:
>>> [a if a else 2 for a in [0,1,0,3]]
[2, 1, 2, 3]
So for your example,
table = ''.join(chr(index) if index in ords_to_keep else replace_with
for index in xrange(15))
Structure in C
First you need to declare your structure:
struct mystruct{
char element_1,
char element_2
};
Instantiate C structure
Once you declared your structure , you can instantiate a variable that has as type your structure using either:
mystruct struct_example;
or :
mystruct* struct_example;
For the first use case you can access the varaiable eleemnet using the following syntax: struct_example.element_1 = 5;
For the second use case which is having a pointer to variable of type your structure, to be able to access the variable structure you need an arrow:
struct_example->element_1 = 5;
ListenForClients
is getting invoked twice (on two different threads) - once from the constructor, once from the explicit method call in Main
. When two instances of the TcpListener
try to listen on the same port, you get that error.
Assuming you have only one record with null in EndDate column for a given RecordID, something like this should give you desired output :
WITH cte1 AS
(
SELECT recordid, MIN(startdate) as min_start , MAX(enddate) as max_end
FROM tmp
GROUP BY recordid
)
SELECT a.recordid, a.min_start ,
CASE
WHEN b.recordid IS NULL THEN a.max_end
END as max_end
FROM cte1 a
LEFT JOIN tmp b ON (b.recordid = a.recordid AND b.enddate IS NULL)
Allowed default size of URI is 8177 characters in GET request. Simple code in python for such testing.
#!/usr/bin/env python2

if __name__ == "__main__":
string = sys.argv[1]
buf_get = "x" * int(string)
buf_size = 1024
request = "HEAD %s HTTP/1.1\nHost:localhost\n\n" % buf_get
print "===>", request
sock_http = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock_http.connect(("localhost", 80))
sock_http.send(request)
while True:
print "==>", sock_http.recv(buf_size)
if not sock_http.recv(buf_size):
break
sock_http.close()
On 8178 characters you will get such message: HTTP/1.1 414 Request-URI Too Large

Play with template to match your needs. Examples and doc here to help you build the template you need.
You may want to cache your DateFormatter
if you plan to use it in TableView
for instance.
To give an idea, looping over 1000 dates took me 0.5 sec using the above toString(template: String)
function, compared to 0.05 sec using myFormatter.string(from: Date)
.
You're doing a few things wrong.
First, browserHistory isn't a thing in V4, so you can remove that.
Second, you're importing everything from react-router
, it should be react-router-dom
.
Third, react-router-dom
doesn't export a Router
, instead, it exports a BrowserRouter
so you need to import { BrowserRouter as Router } from 'react-router-dom
.
Looks like you just took your V3 app and expected it to work with v4, which isn't a great idea.
Try:
$articles = DB::table('articles')
->select('articles.id as articles_id', ..... )
->join('categories', 'articles.categories_id', '=', 'categories.id')
->join('users', 'articles.user_id', '=', 'user.id')
->get();
The best way is:
$ docker cp CONTAINER:FILEPATH LOCALFILEPATH
$ vi LOCALFILEPATH
$ docker cp LOCALFILEPATH CONTAINER:FILEPATH
Limitations with $ docker exec: it can only attach to a running container.
Limitations with $ docker run: it will create a new container.
Perhaps appending DateTime.Now.Ticks
instead, is a tiny bit faster since you won't be creating 3 strings and the ticks value will always be unique also.
It no longer suffices to start Chrome with --user-data-dir=/root/.config/google-chrome
. It simply prints Aborted
and ends (Chrome 48 on Ubuntu 12.04).
You need actually to run it as a non-root user. This you can do with
gksu -wu chrome-user google-chrome
where chrome-user
is some user you've decided should be the one to run Chrome. Your Chrome user profile will be found at ~chrome-user/.config/google-chrome
.
BTW, the old hack of changing all occurrences of geteuid
to getppid
in the chrome
binary no longer works.
None of them will copy, but the second will refer to a destroyed vector. Named rvalue references almost never exist in regular code. You write it just how you would have written a copy in C++03.
std::vector<int> return_vector()
{
std::vector<int> tmp {1,2,3,4,5};
return tmp;
}
std::vector<int> rval_ref = return_vector();
Except now, the vector is moved. The user of a class doesn't deal with it's rvalue references in the vast majority of cases.
I solved this problem by first verifying the that remote did not have anything checked out (it really was not supposed to), and then made it bare with:
$ git config --bool core.bare true
After that git push worked fine.
I Hope this will help you.

It appears as though 'Array.prototype.includes' now has widespread support in the latest versions of the mainline browsers (compatibility)
Update 29-07-2015:
There are plans in the works for browsers to support a standardized 'Array.prototype.includes' method, which although does not directly answer this question; is often related.
Usage:
["1", "1", "2", "3", "3", "1"].includes("2"); // true
Pollyfill (browser support, source from mozilla):
// https://tc39.github.io/ecma262/#sec-array.prototype.includes
if (!Array.prototype.includes) {
Object.defineProperty(Array.prototype, 'includes', {
value: function(searchElement, fromIndex) {
// 1. Let O be ? ToObject(this value).
if (this == null) {
throw new TypeError('"this" is null or not defined');
}
var o = Object(this);
// 2. Let len be ? ToLength(? Get(O, "length")).
var len = o.length >>> 0;
// 3. If len is 0, return false.
if (len === 0) {
return false;
}
// 4. Let n be ? ToInteger(fromIndex).
// (If fromIndex is undefined, this step produces the value 0.)
var n = fromIndex | 0;
// 5. If n = 0, then
// a. Let k be n.
// 6. Else n < 0,
// a. Let k be len + n.
// b. If k < 0, let k be 0.
var k = Math.max(n >= 0 ? n : len - Math.abs(n), 0);
// 7. Repeat, while k < len
while (k < len) {
// a. Let elementK be the result of ? Get(O, ! ToString(k)).
// b. If SameValueZero(searchElement, elementK) is true, return true.
// c. Increase k by 1.
// NOTE: === provides the correct "SameValueZero" comparison needed here.
if (o[k] === searchElement) {
return true;
}
k++;
}
// 8. Return false
return false;
}
});

Adding to the existing answers, an alias could be created to show the diff and/or log prior to a merge. Many answers omit the fetch
to be done first before "previewing" the merge; this is an alias that combines these two steps into one (emulating something similar to mercurial's hg incoming
/ outgoing
)
So, building on "git log ..otherbranch
", you can add the following to ~/.gitconfig
:
...
[alias]
# fetch and show what would be merged (use option "-p" to see patch)
incoming = "!git remote update -p; git log ..@{u}"
For symmetry, the following alias can be used to show what is committed and would be pushed, prior to pushing:
# what would be pushed (currently committed)
outgoing = log @{u}..
And then you can run "git incoming
" to show a lot of changes, or "git incoming -p
" to show the patch (i.e., the "diff"), "git incoming --pretty=oneline
", for a terse summary, etc. You may then (optionally) run "git pull
" to actually merge. (Though, since you've already fetched, the merge could be done directly.)
Likewise, "git outgoing
" shows what would be pushed if you were to run "git push
".
This works:
var img = document.createElement('img');
img.src = 'img/eqp/' + this.apparel + '/' + this.facing + '_idle.png';
document.getElementById('gamediv').appendChild(img)
Or using jQuery:
$('<img/>')
.attr('src','img/eqp/' + this.apparel + '/' + this.facing + '_idle.png')
.appendTo('#gamediv');
Bootstrap 2.x
You could create a new CSS class such as:
.img-center {margin:0 auto;}
And then, add this to each IMG:
<img src="images/2.png" class="img-responsive img-center">
OR, just override the .img-responsive
if you're going to center all images..
.img-responsive {margin:0 auto;}
Demo: http://bootply.com/86123
Bootstrap 3.x
EDIT - With the release of Bootstrap 3.0.1, the center-block
class can now be used without any additional CSS..
<img src="images/2.png" class="img-responsive center-block">
Bootstrap 4
In Bootstrap 4, the mx-auto
class (auto x-axis margins) can be used to center images that are display:block
. However, img is display:inline
by default so text-center
can be used on the parent.
<div class="container">
<div class="row">
<div class="col-12">
<img class="mx-auto d-block" src="//placehold.it/200">
</div>
</div>
<div class="row">
<div class="col-12 text-center">
<img src="//placehold.it/200">
</div>
</div>
</div>

The problem could be due to too many users accessing the db at the same time. Either increase number of users that can concurrently access the db or kick out existing users (or apps). Use "Show processlist;" in the host DB to check connected users;
I came across another reason, catalina.policy file, could prohibit accessing specific IP/PORT

Since this was asked there were a bit of new developments: it is important to know that std::isnan()
is part of C++11
Defined in header <cmath>
bool isnan( float arg ); (since C++11)
bool isnan( double arg ); (since C++11)
bool isnan( long double arg ); (since C++11)
Determines if the given floating point number arg is not-a-number (NaN
).
Parameters
arg
: floating point value
Return value
true
if arg is NaN
, false
otherwise
Reference
http://en.cppreference.com/w/cpp/numeric/math/isnan
Please note that this is incompatible with -fast-math if you use g++, see below for other suggestions.
For C99, in C, this is implemented as a macro isnan(c)
that returns an int value. The type of x
shall be float, double or long double.
Various vendors may or may not include or not a function isnan()
.
The supposedly portable way to check for NaN
is to use the IEEE 754 property that NaN
is not equal to itself: i.e. x == x
will be false for x
being NaN
.
However the last option may not work with every compiler and some settings (particularly optimisation settings), so in last resort, you can always check the bit pattern ...
I think this message is not about avoiding to use switch
. Instead it wants you to check for hasOwnProperty

You can search for "Ajax Behavior Events" in PrimeFaces User's Guide, and you will find plenty of them for all supported components. That's also what PrimeFaces lead Optimus Prime suggest to do in this related question at the PrimeFaces forum <p:ajax>
event list?
There is no onblur
event, that's the HTML attribute name, but there is a blur
event. It's just without the "on" prefix like as the HTML attribute name. You can also look at all "on*" attributes of the tag documentation of the component in question to see which are all available, e.g. <p:inputText>
.
Knowledge of high level programming languages (C/C++, Java, PHP, Python, Perl, etc.) would suggest to the layman that Bourne Again Shell (Bash) functions should work like they do in those other languages.
Instead, Bash functions work like shell commands and expect arguments to be passed to them in the same way one might pass an option to a shell command (e.g. ls -l
). In effect, function arguments in Bash are treated as positional parameters ($1, $2..$9, ${10}, ${11}
, and so on). This is no surprise considering how getopts
works. Do not use parentheses to call a function in Bash.
(Note: I happen to be working on OpenSolaris at the moment.)

Want to use names for variables? Just do something this.
local filename=$1 # The keyword declare can be used, but local is semantically more specific.
Be careful, though. If an argument to a function has a space in it, you may want to do this instead! Otherwise, $1
might not be what you think it is.
local filename="$1" # Just to be on the safe side. Although, if $1 was an integer, then what? Is that even possible? Humm.
Want to pass an array to a function?
callingSomeFunction "${someArray[@]}" # Expands to all array elements.
Inside the function, handle the arguments like this.
function callingSomeFunction ()
{
for value in "$@" # You want to use "$@" here, not "$*" !!!!!
do
:
done
}
Need to pass a value and an array, but still use "$@" inside the function?
function linearSearch ()
{
local myVar="$1"
shift 1 # Removes $1 from the parameter list
for value in "$@" # Represents the remaining parameters.
do
if [[ $value == $myVar ]]
then
echo -e "Found it!\t... after a while."
return 0
fi
done
return 1
}
linearSearch $someStringValue "${someArray[@]}"
Edit: These are library functions. Following them is the manual way to do it.

As you probably understood from previous answers, you can't really do what you're after. I think you can understand the problem SQL Server is experiencing with not knowing how to map the additional/missing columns.
That said, since you mention that the purpose of what you're trying to here is backup, maybe we can work with SQL Server and workaround the issue. Not knowing your exact scenario makes it impossible to hit with a right answer here, but I assume the following:
I wish to suggest two options for you:
The efficient practice (IMO) for this can be to detect schema changes using DDL triggers and use them to alter the backup table accordingly. This will enable you to use the 'select * from...' approach, because the column list will be consistent between the two tables.
I have used this approach successfully and you can leverage it to have DDL triggers automatically manage your auditing tables. In my case, I used a naming convention for a table requiring audits and the DDL trigger just managed it on the fly.
Another option that might be useful for your specific scenario is to create a supporting view for the tables aligning the column list. Here's a quick example:
create table foo (id int, name varchar(50))
create table foo_bk (id int, name varchar(50), tagid int)
go
create view vw_foo as select id,name from foo
go
create view vw_foo_bk as select id,name from foo_bk
go
insert into vw_foo
select * from vw_foo_bk
go
drop view vw_foo
drop view vw_foo_bk
drop table foo
drop table foo_bk
go
I hope this helps :)
Consider using axios
axios.get( url,
{ headers: {"Content-Type": "application/json"} } ).then( res => {
if(res.data.error) {
} else {
doAnything( res.data )
}
}).catch(function (error) {
doAnythingError(error)
});
I had this issue using fetch and axios worked perfectly.
Off the top of my head I think it should be done like this:
var veggies = "carrot";
var fruitvegbasket = [];
fruitvegbasket.push(veggies);
That solution will open up a new browser window without the normal features such as address bar and similar.
To implement a modal popup, I suggest you to take a look at jQuery and SimpleModal, which is really slick.

dtpFromEffDate.Value = new DateTime(dCalcDate.Year, dCalcDate.Month, 1);

I'd like to add something to the very good answer of @CodeWarrior, that works perfectly on Chrome, but for Firefox needs an additional step.
Since Firefox does not thrust CA Certificates that Windows does by default, you need to go on about:config
, scroll down to security.enterprise_roots.enabled
and change it to true.
Now your certificate should be seen as valid also on Firefox.
Of course this is only for development purposes, since ssl trust is a critical security concern and change this settings only if you know the implications.
Whether a monad has a "natural" interpretation in OO depends on the monad. In a language like Java, you can translate the maybe monad to the language of checking for null pointers, so that computations that fail (i.e., produce Nothing in Haskell) emit null pointers as results. You can translate the state monad into the language generated by creating a mutable variable and methods to change its state.
A monad is a monoid in the category of endofunctors.
The information that sentence puts together is very deep. And you work in a monad with any imperative language. A monad is a "sequenced" domain specific language. It satisfies certain interesting properties, which taken together make a monad a mathematical model of "imperative programming". Haskell makes it easy to define small (or large) imperative languages, which can be combined in a variety of ways.
As an OO programmer, you use your language's class hierarchy to organize the kinds of functions or procedures that can be called in a context, what you call an object. A monad is also an abstraction on this idea, insofar as different monads can be combined in arbitrary ways, effectively "importing" all of the sub-monad's methods into the scope.
Architecturally, one then uses type signatures to explicitly express which contexts may be used for computing a value.
One can use monad transformers for this purpose, and there is a high quality collection of all of the "standard" monads:
with corresponding monad transformers and type classes. Type classes allow a complementary approach to combining monads by unifying their interfaces, so that concrete monads can implement a standard interface for the monad "kind". For example, the module Control.Monad.State contains a class MonadState s m, and (State s) is an instance of the form
instance MonadState s (State s) where
put = ...
get = ...
The long story is that a monad is a functor which attaches "context" to a value, which has a way to inject a value into the monad, and which has a way to evaluate values with respect to the context attached to it, at least in a restricted way.
So:
return :: a -> m a
is a function which injects a value of type a into a monad "action" of type m a.
(>>=) :: m a -> (a -> m b) -> m b
is a function which takes a monad action, evaluates its result, and applies a function to the result. The neat thing about (>>=) is that the result is in the same monad. In other words, in m >>= f, (>>=) pulls the result out of m, and binds it to f, so that the result is in the monad. (Alternatively, we can say that (>>=) pulls f into m and applies it to the result.) As a consequence, if we have f :: a -> m b, and g :: b -> m c, we can "sequence" actions:
m >>= f >>= g
Or, using "do notation"
do x <- m
y <- f x
g y
The type for (>>) might be illuminating. It is
(>>) :: m a -> m b -> m b
It corresponds to the (;) operator in procedural languages like C. It allows do notation like:
m = do x <- someQuery
someAction x
theNextAction
andSoOn
In mathematical and philosopical logic, we have frames and models, which are "naturally" modelled with monadism. An interpretation is a function which looks into the model's domain and computes the truth value (or generalizations) of a proposition (or formula, under generalizations). In a modal logic for necessity, we might say that a proposition is necessary if it is true in "every possible world" -- if it is true with respect to every admissible domain. This means that a model in a language for a proposition can be reified as a model whose domain consists of collection of distinct models (one corresponding to each possible world). Every monad has a method named "join" which flattens layers, which implies that every monad action whose result is a monad action can be embedded in the monad.
join :: m (m a) -> m a
More importantly, it means that the monad is closed under the "layer stacking" operation. This is how monad transformers work: they combine monads by providing "join-like" methods for types like
newtype MaybeT m a = MaybeT { runMaybeT :: m (Maybe a) }
so that we can transform an action in (MaybeT m) into an action in m, effectively collapsing layers. In this case, runMaybeT :: MaybeT m a -> m (Maybe a) is our join-like method. (MaybeT m) is a monad, and MaybeT :: m (Maybe a) -> MaybeT m a is effectively a constructor for a new type of monad action in m.
A free monad for a functor is the monad generated by stacking f, with the implication that every sequence of constructors for f is an element of the free monad (or, more exactly, something with the same shape as the tree of sequences of constructors for f). Free monads are a useful technique for constructing flexible monads with a minimal amount of boiler-plate. In a Haskell program, I might use free monads to define simple monads for "high level system programming" to help maintain type safety (I'm just using types and their declarations. Implementations are straight-forward with the use of combinators):
data RandomF r a = GetRandom (r -> a) deriving Functor
type Random r a = Free (RandomF r) a
type RandomT m a = Random (m a) (m a) -- model randomness in a monad by computing random monad elements.
getRandom :: Random r r
runRandomIO :: Random r a -> IO a (use some kind of IO-based backend to run)
runRandomIO' :: Random r a -> IO a (use some other kind of IO-based backend)
runRandomList :: Random r a -> [a] (some kind of list-based backend (for pseudo-randoms))
Monadism is the underlying architecture for what you might call the "interpreter" or "command" pattern, abstracted to its clearest form, since every monadic computation must be "run", at least trivially. (The runtime system runs the IO monad for us, and is the entry point to any Haskell program. IO "drives" the rest of the computations, by running IO actions in order).
The type for join is also where we get the statement that a monad is a monoid in the category of endofunctors. Join is typically more important for theoretical purposes, in virtue of its type. But understanding the type means understanding monads. Join and monad transformer's join-like types are effectively compositions of endofunctors, in the sense of function composition. To put it in a Haskell-like pseudo-language,
Foo :: m (m a) <-> (m . m) a

withColumn is df function. So below will not work in RDD style as used above.
parts.withColumn("index",monotonically_increasing_id()).filter(index > 14)
SCSS+Compass makes this a snap, since we're talking about pre-processors.

One thing you can limit is the amount of memory mongodb uses while building indexes. This is set using the maxIndexBuildMemoryUsageMegabytes
setting. An example of how its set is below:
mongo --eval "db.adminCommand( { setParameter: 1, maxIndexBuildMemoryUsageMegabytes: 70000 } )"
You'll want to do a transform as such:
with JavaScript:
document.getElementById(yourtarget).setAttribute("transform", "scale(2.0)");
With CSS:
#yourtarget {
transform:scale(2.0);
-webkit-transform:scale(2.0);
}
Wrap your SVG Page in a Group tag as such and target it to manipulate the whole page:
<svg>
<g id="yourtarget">
your svg page
</g>
</svg>
Note: Scale 1.0 is 100%
Javascript string objects have a toLocaleUpperCase()
function that makes the conversion itself easy.
Here's an example of live capitalisation:
$(function() {
$('input').keyup(function() {
this.value = this.value.toLocaleUpperCase();
});
});
Unfortunately, this resets the textbox contents completely, so the user's caret position (if not "the end of the textbox") is lost.
You can hack this back in, though, with some browser-switching magic:
// Thanks http://blog.vishalon.net/index.php/javascript-getting-and-setting-caret-position-in-textarea/
function getCaretPosition(ctrl) {
var CaretPos = 0; // IE Support
if (document.selection) {
ctrl.focus();
var Sel = document.selection.createRange();
Sel.moveStart('character', -ctrl.value.length);
CaretPos = Sel.text.length;
}
// Firefox support
else if (ctrl.selectionStart || ctrl.selectionStart == '0') {
CaretPos = ctrl.selectionStart;
}
return CaretPos;
}
function setCaretPosition(ctrl, pos) {
if (ctrl.setSelectionRange) {
ctrl.focus();
ctrl.setSelectionRange(pos,pos);
}
else if (ctrl.createTextRange) {
var range = ctrl.createTextRange();
range.collapse(true);
range.moveEnd('character', pos);
range.moveStart('character', pos);
range.select();
}
}
// The real work
$(function() {
$('input').keyup(function() {
// Remember original caret position
var caretPosition = getCaretPosition(this);
// Uppercase-ize contents
this.value = this.value.toLocaleUpperCase();
// Reset caret position
// (we ignore selection length, as typing deselects anyway)
setCaretPosition(this, caretPosition);
});
});
Ultimately, it might be easiest to fake it. Set the style text-transform: uppercase
on the textbox so that it appears uppercase to the user, then in your Javascript apply the text transformation once whenever the user's caret focus leaves the textbox entirely:
HTML:
<input type="text" name="keywords" class="uppercase" />
CSS:
input.uppercase { text-transform: uppercase; }
Javascript:
$(function() {
$('input').focusout(function() {
// Uppercase-ize contents
this.value = this.value.toLocaleUpperCase();
});
});
Hope this helps.
In case you're sure you have only one space between two words, you can use this one
str.replace(/\s+/g, ' ').split(' ')
so you replace one space by two, the split by space
anyway you have not a unlimited accuracy so C define a constant in this way:
#define PI 3.14159265358979323846
import math.h to use this
Changing to Java SDK to Java 8 and worked for me
Android Studio settings:
File > other settings > Default project structure > JDK location > jdk1.8.0_71.jdk/Contents/Home
you can also use the Activity Monitor
to stop the py process
I had a similar problem and found that if you remove the size definition, it works for some reason.
Remove:
<size
android:width="60dp"
android:height="40dp" />
from the shape.
Let me know if this works!
One thing you need to realize is in Ruby everything is an object. Given that, if you don't define your methods within Module
or Class
, Ruby will put it within the Object
class. So, your code will be local to the Object
scope.
A typical approach on Object Oriented Programming is encapsulate all logic within a class:
class Point
attr_accessor :x, :y
# If we don't specify coordinates, we start at 0.
def initialize(x = 0, y = 0)
# Notice that `@` indicates instance variables.
@x = x
@y = y
end
# Here we override the `+' operator.
def +(point)
Point.new(self.x + point.x, self.y + point.y)
end
# Here we draw the point.
def draw(offset = nil)
if offset.nil?
new_point = self
else
new_point = self + offset
end
new_point.draw_absolute
end
def draw_absolute
puts "x: #{self.x}, y: #{self.y}"
end
end
first_point = Point.new(100, 200)
second_point = Point.new(3, 4)
second_point.draw(first_point)
Hope this clarifies a bit.
Isn't the difference between your declaration of USERID the problem
JOB: UserID is Varchar
USER: UserID is Number?
Depends on the language, but there are generally negative-assertions you can put in like so:
(?!red|green|blue)
(Thanks for the syntax fix, the above is valid Java and Perl, YMMV)
Try
SwingUtilities.updateComponentTreeUI(frame);
If it still doesn't work then after completing the above step try

The simplest way to connect is through an OdbcConnection using code like this
using System.Data.Odbc;
using(OdbcConnection myConnection = new OdbcConnection())
{
myConnection.ConnectionString = myConnectionString;
myConnection.Open();
//execute queries, etc
}
where myConnectionString is something like this
myConnectionString = @"Driver={Microsoft Access Driver (*.mdb)};" +
"Dbq=C:\mydatabase.mdb;Uid=Admin;Pwd=;
In alternative you could create a DSN and then use that DSN in your connection string
now your connectionString could be written in this way
myConnectionString = "DSN=myDSN;"
Use this:
Format(Now, "MMMM dd, yyyy")
More: Format Function
There are two issues are at play here:
The CSS 2.1 specification states that "The :before
and :after
pseudo-elements elements interact with other boxes, such as run-in boxes, as if they were real elements inserted just inside their associated element." Given the way z-indexes are implemented in most browsers, it's pretty difficult (read, I don't know of a way) to move content lower than the z-index of their parent element in the DOM that works in all browsers.
Number 1 above does not necessarily mean it's impossible, but the second impediment to it is actually worse: Ultimately it's a matter of browser support. Firefox didn't support positioning of generated content at all until FF3.6. Who knows about browsers like IE. So even if you can find a hack to make it work in one browser, it's very likely it will only work in that browser.
The only thing I can think of that's going to work across browsers is to use javascript to insert the element rather than CSS. I know that's not a great solution, but the :before
and :after
pseudo-selectors just really don't look like they're gonna cut it here.
The accepted answer is fine if you can use lookarounds. However, there is also another approach to solve this problem.
If we look at the widely proposed regex for this question:
.*[^a]$
We will find that it almost works. It does not accept an empty string, which might be a little inconvinient. However, this is a minor issue when dealing with just a one character. However, if we want to exclude whole string, e.g. "abc", then:
.*[^a][^b][^c]$
won't do. It won't accept ac, for example.
There is an easy solution for this problem though. We can simply say:
.{,2}$|.*[^a][^b][^c]$
or more generalized version:
.{,n-1}$|.*[^firstchar][^secondchar]$
where n is length of the string you want forbid (for abc
it's 3), and firstchar
, secondchar
, ... are first, second ... nth characters of your string (for abc
it would be a
, then b
, then c
).
This comes from a simple observation that a string that is shorter than the text we won't forbid can not contain this text by definition. So we can either accept anything that is shorter("ab" isn't "abc"), or anything long enough for us to accept but without the ending.
Here's an example of find that will delete all files that are not .jpg:
find . -regex '.{,3}$|.*[^.][^j][^p][^g]$' -delete
// 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!"); }
}
);
Try this simple solution to convert file to base64 string
String base64String = imageFileToByte(file);
public String imageFileToByte(File file){
Bitmap bm = BitmapFactory.decodeFile(file.getAbsolutePath());
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is the bitmap object
byte[] b = baos.toByteArray();
return Base64.encodeToString(b, Base64.DEFAULT);
}
Unity is just an IoC "container". Google StructureMap and try it out instead. A bit easier to grok, I think, when the IoC stuff is new to you.
Basically, if you understand IoC then you understand that what you're doing is inverting the control for when an object gets created.
Without IoC:
public class MyClass
{
IMyService _myService;
public MyClass()
{
_myService = new SomeConcreteService();
}
}
With IoC container:
public class MyClass
{
IMyService _myService;
public MyClass(IMyService myService)
{
_myService = myService;
}
}
Without IoC, your class that relies on the IMyService has to new-up a concrete version of the service to use. And that is bad for a number of reasons (you've coupled your class to a specific concrete version of the IMyService, you can't unit test it easily, you can't change it easily, etc.)
With an IoC container you "configure" the container to resolve those dependencies for you. So with a constructor-based injection scheme, you just pass the interface to the IMyService dependency into the constructor. When you create the MyClass with your container, your container will resolve the IMyService dependency for you.
Using StructureMap, configuring the container looks like this:
StructureMapConfiguration.ForRequestedType<MyClass>().TheDefaultIsConcreteType<MyClass>();
StructureMapConfiguration.ForRequestedType<IMyService>().TheDefaultIsConcreteType<SomeConcreteService>();
So what you've done is told the container, "When someone requests the IMyService, give them a copy of the SomeConcreteService." And you've also specified that when someone asks for a MyClass, they get a concrete MyClass.
That's all an IoC container really does. They can do more, but that's the thrust of it - they resolve dependencies for you, so you don't have to (and you don't have to use the "new" keyword throughout your code).
Final step: when you create your MyClass, you would do this:
var myClass = ObjectFactory.GetInstance<MyClass>();
Hope that helps. Feel free to e-mail me.
You need to add the element type to the class, otherwise it will not work.
.hide-checkbox { display: none } /* This will not work! */_x000D_
input.hide-checkbox { display: none } /* But this will. */
_x000D_
<input class="hide-checkbox" id="checkbox" />_x000D_
<label for="checkbox">Checkbox</label>
_x000D_
It looks too simple, but try it out!
Use ThisWorkbook
which will refer to the original workbook which holds the code.
Alternatively at code start
Dim Wb As Workbook
Set Wb = ActiveWorkbook
sample code that activates all open books before returning to ThisWorkbook
Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
Wb2.Activate
Next
Wb.Activate
End Sub
The question is little unclear because the title of the question is asking about string and set conversion but then the question at the end asks how do I serialize ? !
let me refresh the concept of Serialization is the process of encoding an object, including the objects it refers to, as a stream of byte data.
If interested to serialize you can use:
json.dumps -> serialize
json.loads -> deserialize
If your question is more about how to convert set to string and string to set then use below code (it's tested in Python 3)
String to Set
set('abca')
Set to String
''.join(some_var_set)
example:
def test():
some_var_set=set('abca')
print("here is the set:",some_var_set,type(some_var_set))
some_var_string=''.join(some_var_set)
print("here is the string:",some_var_string,type(some_var_string))
test()
So here is how you will do it.
Write a javascript function which fires whenever the window is resized.
window.onresize = function(event) {
var height=$(window).height();
var width=$(window).width();
$.ajax({
url: "/getwindowsize.ashx",
type: "POST",
data : { Height: height,
Width:width,
selectedValue:selectedValue },
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
// do stuff
}
}
Codebehind of Handler:
public class getwindowsize : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "application/json";
string Height = context.Request.QueryString["Height"];
string Width = context.Request.QueryString["Width"];
}
From what I see, people use package.json scripts when they would like to run script in simpler way. For example, to use nodemon
that installed in local node_modules, we can't call nodemon
directly from the cli, but we can call it by using ./node_modules/nodemon/nodemon.js
. So, to simplify this long typing, we can put this...
... scripts: { 'start': 'nodemon app.js' } ...
... then call npm start
to use 'nodemon' which has app.js as the first argument.
What I'm trying to say, if you just want to start your server with the node
command, I don't think you need to use scripts
. Typing npm start
or node app.js
has the same effort.
But if you do want to use nodemon
, and want to pass a dynamic argument, don't use script
either. Try to use symlink instead.
For example using migration with sequelize
. I create a symlink...
ln -s node_modules/sequelize/bin/sequelize sequelize
... And I can pass any arguement when I call it ...
./sequlize -h /* show help */
./sequelize -m /* upgrade migration */
./sequelize -m -u /* downgrade migration */
etc...
At this point, using symlink is the best way I could figure out, but I don't really think it's the best practice.
I also hope for your opinion to my answer.
Our server calls stored procs from Java like so - works on both SQL Server 2000 & 2008:
String SPsql = "EXEC <sp_name> ?,?"; // for stored proc taking 2 parameters
Connection con = SmartPoolFactory.getConnection(); // java.sql.Connection
PreparedStatement ps = con.prepareStatement(SPsql);
ps.setEscapeProcessing(true);
ps.setQueryTimeout(<timeout value>);
ps.setString(1, <param1>);
ps.setString(2, <param2>);
ResultSet rs = ps.executeQuery();
Add the repository and update apt-get:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
Install Java8 and set it as default:
sudo apt-get install oracle-java8-set-default
Check version:
java -version
that depends on what you want to markup.

I tried following the above tutorial. Thing is tensorflow changes a lot and so do the NVIDIA versions needed for running on a GPU. The next issue is that your driver version determines your toolkit version etc. As of today this information about the software requirements should shed some light on how they interplay:
NVIDIA® GPU drivers —CUDA 9.0 requires 384.x or higher.
CUDA® Toolkit —TensorFlow supports CUDA 9.0.
CUPTI ships with the CUDA Toolkit.
cuDNN SDK (>= 7.2) Note: Make sure your GPU has compute compatibility >3.0
(Optional) NCCL 2.2 for multiple GPU support.
(Optional) TensorRT 4.0 to improve latency and throughput for inference on some models.
And here you'll find the up-to-date requirements stated by tensorflow (which will hopefully be updated by them on a regular basis).

This solved the issue for me. I mistakenly installed grunt using:
sudo npm install -g grunt --save-dev
and then ran the following command in the project folder:
npm install
This resulted in the error seen by the author of the question. I then uninstalled grunt using:
sudo npm uninstall -g grunt
Deleted the node_modules folder. And reinstalled grunt using:
npm install grunt --save-dev
and running the following in the project folder:
npm install
For some odd reason when you global install grunt using -g and then uninstall it, the node_modules folder holds on to something that prevents grunt from being installed locally to the project folder.
Easiest fix ever:

Sounds very much like MySQL events that are stored in system tables. You can look at the structure and figure out which columns are not needed:
EVENT_CATALOG: NULL
EVENT_SCHEMA: myschema
EVENT_NAME: e_store_ts

EVENT_BODY: SQL
EVENT_DEFINITION: INSERT INTO myschema.mytable VALUES (UNIX_TIMESTAMP())
EVENT_TYPE: RECURRING
EXECUTE_AT: NULL
INTERVAL_VALUE: 5
INTERVAL_FIELD: SECOND
SQL_MODE: NULL
STARTS: 0000-00-00 00:00:00
ENDS: 0000-00-00 00:00:00
STATUS: ENABLED
ON_COMPLETION: NOT PRESERVE
CREATED: 2006-02-09 22:36:06
LAST_ALTERED: 2006-02-09 22:36:06
LAST_EXECUTED: NULL
EVENT_COMMENT:
When you bind your Service to Activity with BIND_AUTO_CREATE your service is being killed just after your Activity is Destroyed and unbound. It does not depend on how you've implemented your Services unBind method it will be still killed.
The other way is to start your Service with startService method from your Activity. This way even if your Activity is destroyed your service won't be destroyed or even paused but you have to pause/destroy it by yourself with stopSelf/stopService when appropriate.
Very easy, just call the function within a specific amount of milliseconds using setTimeout()
setTimeout(myFunction, 2000)
function myFunction() {
alert('Was called after 2 seconds');
}
Or you can even initiate the function inside the timeout, like so:
setTimeout(function() {
alert('Was called after 2 seconds');
}, 2000)
Another option is an interesting open source project called ScriptCS. It uses some crafty techniques to allow you a development experience outside of Visual Studio while still being able to leverage NuGet to manage your dependencies. It's free, very easy to install using Chocolatey. You can check it out here http://scriptcs.net.
Another cool feature it has is the REPL from the command line. Which allows you to do stuff like this:
C:\> scriptcs
scriptcs (ctrl-c or blank to exit)
> var message = "Hello, world!";
> Console.WriteLine(message);
Hello, world!
>
C:\>
You can create C# utility "scripts" which can be anything from small system tasks, to unit tests, to full on Web APIs. In the latest release I believe they're also allowing for hosting the runtime in your own apps.
Check out it development on the GitHub page too https://github.com/scriptcs/scriptcs

You can generate pairs like this:
{(x, x + 2) for x in r if x + 2 in r}
Then all that is left to do is to get a condition to make them prime, which you have already done in the first example.
A different way of doing it: (Although slower for large sets of primes)
{(x, y) for x in r for y in r if x + 2 == y}
You can use std::set
instead of std::map
.
You can store both key and value in std::pair
and the type of container will look like this:
std::set< std::pair<int, std::string> > items;
std::set
will sort it's values both by original keys and values that were stored in std::map
.
Do something like this, which also prevents SQL injection attacks
statement = con.prepareStatement("SELECT * from employee WHERE userID = ?");
statement.setString(1, userID);
ResultSet rs = statement.executeQuery();
I had a similar issue with an integer that could be legitimately assigned 0 in Access VBA. None of the above solutions worked for me.
At first I just used a boolean var and IF statement:
Dim i as integer, bol as boolean
If bol = false then
i = ValueIWantToAssign
bol = True
End If
In my case, my integer variable assignment was within a for loop and another IF statement, so I ended up using "Exit For" instead as it was more concise.
Like so:
Dim i as integer
ForLoopStart
If ConditionIsMet Then
i = ValueIWantToAssign
Exit For
End If
ForLoopEnd
It's worth the buck to apply for the Apple developer program. You will be able to use ad-hoc provisioning to distribute your app to testers and test devices. You're allowed to add 100 ad-hoc provisioning devices to your developer program.
Another solution would be to write a wrapper that store the array like this:
localStorage.setItem('names_length', names.length);
localStorage.setItem('names_0', names[0]);
localStorage.setItem('names_1', names[1]);
localStorage.setItem('names_' + n, names[n]);
Removes the overhead of converting to JSON, but would be annoying if you need to remove elements, as you would have to re-index the array :)

Parallel.ForEach will optimize(may not even start new threads) and block until the loop is finished, and Task.Factory will explicitly create a new task instance for each item, and return before they are finished (asynchronous tasks). Parallel.Foreach is much more efficient.
If you want to ask based on condition:
var ask = true
window.onbeforeunload = function (e) {
if(!ask) return null
e = e || window.event;
//old browsers
if (e) {e.returnValue = 'Sure?';}
//safari, chrome(chrome ignores text)
return 'Sure?';
};
Are you working with a @Service
too? Because if you are, then you can @Autowired
your PersonRepository
to the @Service
and then in the service just invoke the Name
class and use the form that @CuriosMind... proposed:
@Query(select p from Person p where p.forename = :forename and p.surname = :surname)
User findByForenameAndSurname(@Param("surname") String lastname,
@Param("forename") String firstname);
}
and when invoking the method from the repository in the service, you can then pass those parameters.
If the string you are operating on is very long, or you are operating on many strings, then it could be worthwhile using a java.util.regex.Matcher (this requires time up-front to compile, so it won't be efficient if your input is very small or your search pattern changes frequently).
Below is a full example, based on a list of tokens taken from a map. (Uses StringUtils from Apache Commons Lang).
Map<String,String> tokens = new HashMap<String,String>();
tokens.put("cat", "Garfield");
tokens.put("beverage", "coffee");
String template = "%cat% really needs some %beverage%.";
// Create pattern of the format "%(cat|beverage)%"
String patternString = "%(" + StringUtils.join(tokens.keySet(), "|") + ")%";
Pattern pattern = Pattern.compile(patternString);
Matcher matcher = pattern.matcher(template);
StringBuffer sb = new StringBuffer();
while(matcher.find()) {
matcher.appendReplacement(sb, tokens.get(matcher.group(1)));
}
matcher.appendTail(sb);
System.out.println(sb.toString());
Once the regular expression is compiled, scanning the input string is generally very quick (although if your regular expression is complex or involves backtracking then you would still need to benchmark in order to confirm this!)
The Angular2 team published a tutorial for using Webpack
I created and placed the files from the tutorial in a small GitHub seed project. So you can quickly try the workflow.
Instructions:
npm install
npm start. For development. This will create a virtual "dist" folder that will be livereloaded at your localhost address.
npm run build. For production. "This will create a physical "dist" folder version than can be sent to a webserver. The dist folder is 7.8MB but only 234KB is actually required to load the page in a web browser.
This Webpack Starter Kit offers some more testing features than the above tutorial and seem quite popular.
Another way of doing it. This approach can be useful for changing the text to 2 different colors, just by adding 2 spans.
Label1.Text = "String with original color" + "<b><span style=""color:red;"">" + "Your String Here" + "</span></b>";
In GitHub markdown <ins>
text</ins>
works just fine.
Here's a slightly more flexible approach using the match
method. With this, you can extract more than one string:
s = "<ants> <pants>"
matchdata = s.match(/<([^>]*)> <([^>]*)>/)
# Use 'captures' to get an array of the captures
matchdata.captures # ["ants","pants"]
# Or use raw indices
matchdata[0] # whole regex match: "<ants> <pants>"
matchdata[1] # first capture: "ants"
matchdata[2] # second capture: "pants"
In iTerm -> Preferences -> Profiles Tab -> General section set Command to: /bin/zsh --login
Synchronized simply means that multiple threads if associated with single object can prevent dirty read and write if synchronized block is used on particular object. To give you more clarity , lets take an example :
class MyRunnable implements Runnable {
int var = 10;
@Override
public void run() {
call();
}
public void call() {
synchronized (this) {
for (int i = 0; i < 4; i++) {
var++;
System.out.println("Current Thread " + Thread.currentThread().getName() + " var value "+var);
}
}
}
}
public class MutlipleThreadsRunnable {
public static void main(String[] args) {
MyRunnable runnable1 = new MyRunnable();
MyRunnable runnable2 = new MyRunnable();
Thread t1 = new Thread(runnable1);
t1.setName("Thread -1");
Thread t2 = new Thread(runnable2);
t2.setName("Thread -2");
Thread t3 = new Thread(runnable1);
t3.setName("Thread -3");
t1.start();
t2.start();
t3.start();
}
}
We've created two MyRunnable class objects , runnable1 being shared with thread 1 and thread 3 & runnable2 being shared with thread 2 only. Now when t1 and t3 starts without synchronized being used , PFB output which suggest that both threads 1 and 3 simultaneously affecting var value where for thread 2 , var has its own memory.
Without Synchronized keyword

Pass the decode pattern to ParseExact
Dim d as string = "201210120956"
Dim dt = DateTime.ParseExact(d, "yyyyMMddhhmm", Nothing)
ParseExact is available only from Net FrameWork 2.0.
If you are still on 1.1 you could use Parse, but you need to provide the IFormatProvider adequate to your string
Easier Yet, you can operate directly on $@
;)
Here is how to do pass a a list of args directly from the prompt:
function echoarg { for stuff in "$@" ; do echo $stuff ; done ; }
echoarg Hey Ho Lets Go
Hey

To best mirror Eclipses functionality, enable the following settings:
To see the javadoc in the autocomplete menu, hit '.' to get the popup, then hover over the object you are working with, once you get the javadoc popup, you can select an item in the popup to switch the javadoc over. Not ideal... But its something.
As another note. The search functionality of the options menu is very useful. Just type in 'doc' and you will see all the options for doc.
Also, searching for "autopopup doc" will not only find each of the options, but it will also highlight them in the menu. Pretty awesome!
Edit: Going beyond the initial question, this might be useful for people who just want quick and easy access to the docs.
After using this for a few more days, it seems just getting used to using the hotkey is the most efficient way. It will pop up the documentation for anything at the spot of where your text input marker is so you never have to touch the mouse. This works in the intellisense popup as well and will stay up while navigating up and down.
Personally, Ctrl+Q on windows was not ideal so I remapped it to Alt+D. Remaping can be done under IDE Settings/Keymap. Once in the keymap menu, just search for Quick Documentation.
That attribute is basically the persistence for the "Associated Activity" selection above the layout. At runtime, a layout is always associated with an activity. It can of course be associated with more than one, but at least one. In the tool, we need to know about this mapping (which at runtime happens in the other direction; an activity can call setContentView(layout) to display a layout) in order to drive certain features.
Right now, we're using it for one thing only: Picking the right theme to show for a layout (since the manifest file can register themes to use for an activity, and once we know the activity associated with the layout, we can pick the right theme to show for the layout). In the future, we'll use this to drive additional features - such as rendering the action bar (which is associated with the activity), a place to add onClick handlers, etc.
The reason this is a tools: namespace attribute is that this is only a designtime mapping for use by the tool. The layout itself can be used by multiple activities/fragments etc. We just want to give you a way to pick a designtime binding such that we can for example show the right theme; you can change it at any time, just like you can change our listview and fragment bindings, etc.
(Here's the full changeset which has more details on this)
And yeah, the link Nikolay listed above shows how the new configuration chooser looks and works
One more thing: The "tools" namespace is special. The android packaging tool knows to ignore it, so none of those attributes will be packaged into the APK. We're using it for extra metadata in the layout. It's also where for example the attributes to suppress lint warnings are stored -- as tools:ignore.
For the record, tested with httpclient 4.3.6 and compatible with Executor of fluent api:
CloseableHttpClient httpClient = HttpClients.custom().
setHostnameVerifier(new AllowAllHostnameVerifier()).
setSslcontext(new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy()
{
public boolean isTrusted(X509Certificate[] arg0, String arg1) throws CertificateException
{
return true;
}
}).build()).build();
Swift version, this works in combination with other elements (like a UIButton
or another UITextField
):
override func viewDidLoad() {
super.viewDidLoad()
let tapper = UITapGestureRecognizer(target: self, action:#selector(endEditing))
tapper.cancelsTouchesInView = false
view.addGestureRecognizer(tapper)
}
The only thing that worked for me:
g.drawOval((getWidth()-200)/2,(getHeight()-200)/2, 200, 200);
note, you can also do this within Android Studio by clicking the gradle window, and then the 'elephant' button. This will open a new window called "run anything" (can also be found by searching for that name in 'search everywhere') where you can manually type any gradle command you want in. Not "quite" command line, but often provides more of what I need than windows command line.
This allows you to give optional params to gradle tasks, etc.
You can use also system table_types view
IF EXISTS (SELECT *
FROM [sys].[table_types]
WHERE user_type_id = Type_id(N'[dbo].[UdTableType]'))
BEGIN
PRINT 'EXISTS'
END
I used the earlier answers as a starting point to tidy up my old adhoc param parsing. I then refactored out the following template code. It handles both long and short params, using = or space separated arguments, as well as multiple short params grouped together. Finally it re-inserts any non-param arguments back into the $1,$2.. variables.
#!/usr/bin/env bash

#if [ -z "$BASH_VERSION" ]; then bash $0 $@ ; exit $? ; fi
echo "Before"
for i ; do echo - $i ; done
# Code template for parsing command line parameters using only portable shell
# code, while handling both long and short params, handling '-f file' and
# '-f=file' style param data and also capturing non-parameters to be inserted
# back into the shell positional parameters.
while [ -n "$1" ]; do
# Copy so we can modify it (can't modify $1)
OPT="$1"
# Detect argument termination
if [ x"$OPT" = x"--" ]; then
shift

REMAINS="$REMAINS \"$OPT\""

Solved this issue by updating the Android SDK-Build Tools.
Can anyone tell me why json_encode adds slashes?
Forward slash characters can cause issues (when preceded by a <
it triggers the SGML rules for "end of script element") when embedded in an HTML script element. They are escaped as a precaution.
Because when I try do use jQuery.parseJSON(response); in my js script, it returns null. So my guess it has something to do with the slashes.
It doesn't. In JSON "/"
and "\/"
are equivalent.
The JSON you list in the question is valid (you can test it with jsonlint). Your problem is likely to do with what happens to it between json_encode
and parseJSON
.
If you have a file in your repo that it is supposed to be customized by most pullers, then rename the file to something like config.php.template
and add config.php
to your .gitignore
.
The answer might be inappropriate, but I hope it helps you
class DisableCSRFOnDebug(object):
def process_request(self, request):
if settings.DEBUG:
setattr(request, '_dont_enforce_csrf_checks', True)
Having middleware like this helps to debug requests and to check csrf in production servers.
Well, you may try this '.*[0-9]'
The delete operator deletes only a reference, never an object itself. If it did delete the object itself, other remaining references would be dangling, like a C++ delete. (And accessing one of them would cause a crash. To make them all turn null would mean having extra work when deleting or extra memory for each object.)
Since Javascript is garbage collected, you don't need to delete objects themselves - they will be removed when there is no way to refer to them anymore.
It can be useful to delete references to an object if you are finished with them, because this gives the garbage collector more information about what is able to be reclaimed. If references remain to a large object, this can cause it to be unreclaimed - even if the rest of your program doesn't actually use that object.
if ( ! $("input").is(':checked') )
Doesn't work?
You might also try iterating over the elements like so:
var iz_checked = true;
$('input').each(function(){
iz_checked = iz_checked && $(this).is(':checked');
});
if ( ! iz_checked )
And because I prefer the expression chain syntax, here is how you do it with that:
var dealerContracts = DealerContact.Join(Dealer,
contact => contact.DealerId,
dealer => dealer.DealerId,
(contact, dealer) => contact);

No. NodeJS is not available as an Apache module in the way mod-perl and mod-php are, so it's not possible to run node "on top of" Apache. As hexist pointed out, it's possible to run node as a separate process and arrange communication between the two, but this is quite different to the LAMP stack you're already using.
As a replacement for Apache, node offers performance advantages if you have many simultaneous connections. There's also a huge ecosystem of modules for almost anything you can think of.
From your question, it's not clear if you need to dynamically generate pages on every request, or just generate new content periodically for caching and serving. If its the latter, you could use separate node task to generate content to a directory that Apache would serve, but again, that's quite different to PHP or Perl.
Node isn't the best way to serve static content. Nginx and Varnish are more effective at that. They can serve static content while Node handles the dynamic data.
If you're considering using node for a web application at all, Express should be high on your list. You could implement a web application purely in Node, but Express (and similar frameworks like Flatiron, Derby and Meteor) are designed to take a lot of the pain and tedium away. Although the Express documentation can seem a bit sparse at first, check out the screen casts which are still available here: http://expressjs.com/2x/screencasts.html They'll give you a good sense of what express offers and why it is useful. The github repository for ExpressJS also contains many good examples for everything from authentication to organizing your app.
To give the simplest answer I can think of:
Suppose we have a problem that takes a certain number of inputs, and has various potential solutions, which may or may not solve the problem for given inputs. A logic puzzle in a puzzle magazine would be a good example: the inputs are the conditions ("George doesn't live in the blue or green house"), and the potential solution is a list of statements ("George lives in the yellow house, grows peas, and owns the dog"). A famous example is the Traveling Salesman problem: given a list of cities, and the times to get from any city to any other, and a time limit, a potential solution would be a list of cities in the order the salesman visits them, and it would work if the sum of the travel times was less than the time limit.
Such a problem is in NP if we can efficiently check a potential solution to see if it works. For example, given a list of cities for the salesman to visit in order, we can add up the times for each trip between cities, and easily see if it's under the time limit. A problem is in P if we can efficiently find a solution if one exists.
(Efficiently, here, has a precise mathematical meaning. Practically, it means that large problems aren't unreasonably difficult to solve. When searching for a possible solution, an inefficient way would be to list all possible potential solutions, or something close to that, while an efficient way would require searching a much more limited set.)
Therefore, the P=NP problem can be expressed this way: If you can verify a solution for a problem of the sort described above efficiently, can you find a solution (or prove there is none) efficiently? The obvious answer is "Why should you be able to?", and that's pretty much where the matter stands today. Nobody has been able to prove it one way or another, and that bothers a lot of mathematicians and computer scientists. That's why anybody who can prove the solution is up for a million dollars from the Claypool Foundation.
We generally assume that P does not equal NP, that there is no general way to find solutions. If it turned out that P=NP, a lot of things would change. For example, cryptography would become impossible, and with it any sort of privacy or verifiability on the Internet. After all, we can efficiently take the encrypted text and the key and produce the original text, so if P=NP we could efficiently find the key without knowing it beforehand. Password cracking would become trivial. On the other hand, there's whole classes of planning problems and resource allocation problems that we could solve effectively.
You may have heard the description NP-complete. An NP-complete problem is one that is NP (of course), and has this interesting property: if it is in P, every NP problem is, and so P=NP. If you could find a way to efficiently solve the Traveling Salesman problem, or logic puzzles from puzzle magazines, you could efficiently solve anything in NP. An NP-complete problem is, in a way, the hardest sort of NP problem.
So, if you can find an efficient general solution technique for any NP-complete problem, or prove that no such exists, fame and fortune are yours.
A simple solution might be opening the file in Firefox.
and the text encoding will appear on the "Page Info" window.
Note: If the file is not in txt format, just rename it to txt and try again.
P.S. For more info see this article.
The mySQL client by default attempts to connect through a local file called a socket instead of connecting to the loopback address (127.0.0.1) for localhost.
The default location of this socket file, at least on OSX, is /tmp/mysql.sock
.
QUICK, LESS ELEGANT SOLUTION
Create a symlink to fool the OS into finding the correct socket.
ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp
PROPER SOLUTION
Change the socket path defined in the startMysql.sh
file in /Applications/MAMP/bin
.
String#toLowerCase and String#toUpperCase are the methods you need.
If you're just using toString()
for debugging a DTO, you can generate human readable output automatically with something like the following:
import com.fasterxml.jackson.databind.ObjectMapper;
...
public String toString() {
try { return new ObjectMapper().writeValueAsString(this); }
catch (Exception e) { return "{ObjectMapper failed}"; }
}
However, this isn't appropriate for production deployments if the DTO may contain PII (which shouldn't be captured in logs).
Suppose you have Vue project created with vue-cli (e.g. vue init webpack my-project). Go to project dir and run
npm install jquery --save
Open file build/webpack.base.conf.js
and add plugins
:
module.exports = {
plugins: [
new webpack.ProvidePlugin({
$: 'jquery',
jquery: 'jquery',
'window.jQuery': 'jquery',
jQuery: 'jquery'
})
]
...
}
Also at top of file add:
const webpack = require('webpack')
If you are using ESLint, open .eslintrc.js
and add next globals: {
module.exports = {
globals: {
"$": true,
"jQuery": true
},
...
Now you are ready to go. Use $ anywhere in your js.
NOTE You don't need to include expose loader or any other stuff to use this.
Originally from https://maketips.net/tip/223/how-to-include-jquery-into-vuejs
In 2018 and thenceforth we shall use [...Array(500)]
to that end.
You can use WebClient.
Or (if you need more fine-grained control over the request) HttpWebRequest
Or, HttpClient in System.Net.Http.dll.
Here's a "translation" to HttpWebRequest (needed rather than WebClient in order to set the referrer). (Uses System.Net and System.IO):
HttpWebRequest http = (HttpWebRequest)HttpWebRequest.Create(requestUrl))
http.Referer = referrer;
HttpWebResponse response = (HttpWebResponse )http.GetResponse();
using (StreamReader sr = new StreamReader(response.GetResponseStream()))
{
string responseJson = sr.ReadToEnd();
// more stuff
}
You can capture the system environment variables with a vbs script, but you need a bat script to actually change the current environment variables, so this is a combined solution.
Create a file named resetvars.vbs
containing this code, and save it on the path:
Set oShell = WScript.CreateObject("WScript.Shell")
filename = oShell.ExpandEnvironmentStrings("%TEMP%\resetvars.bat")
Set objFileSystem = CreateObject("Scripting.fileSystemObject")
Set oFile = objFileSystem.CreateTextFile(filename, TRUE)
set oEnv=oShell.Environment("System")
for each sitem in oEnv
oFile.WriteLine("SET " & sitem)
next
path = oEnv("PATH")
set oEnv=oShell.Environment("User")
for each sitem in oEnv
oFile.WriteLine("SET " & sitem)
next
path = path & ";" & oEnv("PATH")
oFile.WriteLine("SET PATH=" & path)
oFile.Close
create another file name resetvars.bat containing this code, same location:
@echo off
%~dp0resetvars.vbs
call "%TEMP%\resetvars.bat"
When you want to refresh the environment variables, just run resetvars.bat
Apologetics:
The two main problems I had coming up with this solution were
a. I couldn't find a straightforward way to export environment variables from a vbs script back to the command prompt, and
b. the PATH environment variable is a concatenation of the user and the system PATH variables.
I'm not sure what the general rule is for conflicting variables between user and system, so I elected to make user override system, except in the PATH variable which is handled specifically.
I use the weird vbs+bat+temporary bat mechanism to work around the problem of exporting variables from vbs.
Note: this script does not delete variables.
This can probably be improved.
ADDED
If you need to export the environment from one cmd window to another, use this script (let's call it exportvars.vbs
):
Set oShell = WScript.CreateObject("WScript.Shell")
filename = oShell.ExpandEnvironmentStrings("%TEMP%\resetvars.bat")
Set objFileSystem = CreateObject("Scripting.fileSystemObject")
Set oFile = objFileSystem.CreateTextFile(filename, TRUE)
set oEnv=oShell.Environment("Process")
for each sitem in oEnv
oFile.WriteLine("SET " & sitem)
next
oFile.Close
Run exportvars.vbs
in the window you want to export from, then switch to the window you want to export to, and type:
"%TEMP%\resetvars.bat"
My classes contained a main()
method yet I was unable to see the Run option. That option was enabled once I marked a folder containing my class files as a source folder:
Some of the classes in my folder don't have a main()
method, but I still see a Run option for those.
Quite simple:
$input = array(
array(
'tag_name' => 'google'
),
array(
'tag_name' => 'technology'
)
);
echo implode(', ', array_map(function ($entry) {
return $entry['tag_name'];
}, $input));
and new in php v5.5.0, array_column
:
echo implode(', ', array_column($input, 'tag_name'));
The script tag to the api has changed recently. Use something like this to query the Geocoding API and get the JSON object back
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/geocode/json?address=THE_ADDRESS_YOU_WANT_TO_GEOCODE&key=YOUR_API_KEY"></script>
The address could be something like
1600+Amphitheatre+Parkway,+Mountain+View,+CA (URI Encoded; you should Google it. Very useful)
or simply
1600 Amphitheatre Parkway, Mountain View, CA
By entering this address https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY
inside the browser, along with my API Key, I get back a JSON object which contains the Latitude & Longitude for the city of Moutain view, CA.

Hope this will help....For python version 3.7.3 in vscode with gitbash as the default terminal I was dealing with this for a while and then followed @Vitaliy Terziev advice of adding the alias to .bashrc but with the following specification:
alias python=’“/c/Users/my user name/AppData/Local/Programs/Python/Python37/python.exe”’
Notice the combination of single and double quotes because of “my user name” spaces.
For me, "winpty" couldn't resolve python path in vscode.

Here's a simple class for URL Validation using RegEx and then cross-references the domain against popular RBL (Realtime Blackhole Lists) servers:
Install:
require 'URLValidation.php';
Usage:
require 'URLValidation.php';
$urlVal = new UrlValidation(); //Create Object Instance
Add a URL as the parameter of the domain()
method and check the the return.
$urlArray = ['http://www.bokranzr.com/test.php?test=foo&test=dfdf', 'https://en-gb.facebook.com', 'https://www.google.com'];
foreach ($urlArray as $k=>$v) {
echo var_dump($urlVal->domain($v)) . ' URL: ' . $v . '<br>';
}
Output:
bool(false) URL: http://www.bokranzr.com/test.php?test=foo&test=dfdf
bool(true) URL: https://en-gb.facebook.com
bool(true) URL: https://www.google.com
As you can see above, www.bokranzr.com is listed as malicious website via an RBL so the domain was returned as false.
