In brief
https://github.com/IdentityModel/IdentityModel adds extensions to HttpClient
to acquire tokens using different flows and the documentation is great too. It's very handy because you don't have to think how to implement it yourself. I'm not aware if any official MS implementation exists.
You can use React-Bootstrap (https://react-bootstrap.github.io/components/modal). There is an example for modals at that link. Once you have loaded react-bootstrap, the modal component can be used as a react component:
var Modal = ReactBootstrap.Modal;
can then be used as a react component as
<Modal/>
.
For Bootstrap 4, there is react-strap (https://reactstrap.github.io). React-Bootstrap only supports Bootstrap 3.
In phpMyAdmin you can select multiple rows and can then click the delete action. You'll enter a screen which lists the delete queries. It looks like this:
Please uncheck the "Enable foreign key checks" checkbox, and click on Yes to execute them.
This will enable you to delete rows even if there is an ON DELETE restriction constraint.
since npm 5.2.0, there's a new command "npx" included with npm that makes this much simpler, if you run:
npx mocha <args>
Note: the optional args are forwarded to the command being executed (mocha in this case)
this will automatically pick the executable "mocha" command from your locally installed mocha (always add it as a dev dependency to ensure the correct one is always used by you and everyone else).
Be careful though that if you didn't install mocha, this command will automatically fetch and use latest version, which is great for some tools (like scaffolders for example), but might not be the most recommendable for certain dependencies where you might want to pin to a specific version.
You can read more on npx here
Now, if instead of invoking mocha directly, you want to define a custom npm script, an alias that might invoke other npm binaries...
you don't want your library tests to fail depending on the machine setup (mocha as global, global mocha version, etc), the way to use the local mocha that works cross-platform is:
node node_modules/.bin/mocha
npm puts aliases to all the binaries in your dependencies on that special folder. Finally, npm will add node_modules/.bin to the PATH automatically when running an npm script, so in your package.json you can do just:
"scripts": {
"test": "mocha"
}
and invoke it with
npm test

You can use the infoDictionary which gets the version details from info.plist of you app. This code works for swift 3. Just call this method and display the version in any preferred UI element.
Swift-3
func getVersion() -> String {
let dictionary = Bundle.main.infoDictionary!
let version = dictionary["CFBundleShortVersionString"] as! String
let build = dictionary["CFBundleVersion"] as! String
return "v\(version).\(build)"
}
If you want to persist data on the client machine permanently -or at least until browser cache is emptied completely, use Javascript local storage:
https://developer.mozilla.org/en-US/docs/DOM/Storage#localStorage
Do not use session storage, as it will be cleared just like a cookie with a maximum age of Zero.
This is an old question, and the existing answers describe most of the alternatives. But there's one simple option, if you have bool? in your viewmodel, and you don't care about null in your UI:
@Html.CheckBoxFor(m => m.boolValue ?? false);
use this Reload page
success: function(data){
if(data.success == true){ // if true (1)
setTimeout(function(){// wait for 5 secs(2)
location.reload(); // then reload the page.(3)
}, 5000);
}
}
Open project.properties file and change the line with target=android-22 to the desired value.
For example:
target=android-19
edit the project's settings.gradle file: delete the module name (, ':xxxxx') where xxxxx is the module name to be deleted
using the file explorer delete the module folder
by the way, the current version of the Android Studio (v3.1.2) throws an exception and exits the removing with an error while I'm removing the module through Module Settings => selected module => - (minus)
Best Regards, thanks)
Why not simply use bin log files? If the replication is set on the Mysql server, and binlog file format is set to ROW, then all the changes could be captured.
A good python library called noplay can be used. More info here.
Laravel's Autoload is a bit different:
1) It will in fact use Composer for some stuff
2) It will call Composer with the optimize flag
3) It will 'recompile' loads of files creating the huge bootstrap/compiled.php
4) And also will find all of your Workbench packages and composer dump-autoload them, one by one.
I faced this issue:

In the future, promise rejections that are not handled will terminate the Node.j s process with a non-zero exit code.
It was my mistake, I was replacing res

module.exports.update = function(req, res){
return Services.User.update(req.body)
.then(function(res){//issue was here, res overwrite
return res.json(res);

}).catch(function () {
console.log("Promise Rejected");

mode: 'no-cors'
won’t magically make things work. In fact it makes things worse, because one effect it has is to tell browsers, “Block my frontend JavaScript code from looking at contents of the response body and headers under all circumstances.” Of course you almost never want that.
What happens with cross-origin requests from frontend JavaScript is that browsers by default block frontend code from accessing resources cross-origin. If Access-Control-Allow-Origin
is in a response, then browsers will relax that blocking and allow your code to access the response.
But if a site sends no Access-Control-Allow-Origin
in its responses, your frontend code can’t directly access responses from that site. In particular, you can’t fix it by specifying mode: 'no-cors'
(in fact that’ll ensure your frontend code can’t access the response contents).
However, one thing that will work: if you send your request through a CORS proxy.
You can also easily deploy your own proxy to Heroku in literally just 2-3 minutes, with 5 commands:
git clone https://github.com/Rob--W/cors-anywhere.git
cd cors-anywhere/
npm install
heroku create
git push heroku master
After running those commands, you’ll end up with your own CORS Anywhere server running at, for example, https://cryptic-headland-94862.herokuapp.com/
.
Prefix your request URL with your proxy URL; for example:
https://cryptic-headland-94862.herokuapp.com/https://example.com
Adding the proxy URL as a prefix causes the request to get made through your proxy, which then:
https://example.com
.https://example.com
.Access-Control-Allow-Origin
header to the response.The browser then allows the frontend code to access the response, because that response with the Access-Control-Allow-Origin
response header is what the browser sees.
This works even if the request is one that triggers browsers to do a CORS preflight OPTIONS
request, because in that case, the proxy also sends back the Access-Control-Allow-Headers
and Access-Control-Allow-Methods
headers needed to make the preflight successful.
I can hit this endpoint,
http://catfacts-api.appspot.com/api/facts?number=99
via Postman
https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS explains why it is that even though you can access the response with Postman, browsers won’t let you access the response cross-origin from frontend JavaScript code running in a web app unless the response includes an Access-Control-Allow-Origin
response header.
http://catfacts-api.appspot.com/api/facts?number=99 has no Access-Control-Allow-Origin
response header, so there’s no way your frontend code can access the response cross-origin.
Your browser can get the response fine and you can see it in Postman and even in browser devtools—but that doesn’t mean browsers will expose it to your code. They won’t, because it has no Access-Control-Allow-Origin
response header. So you must instead use a proxy to get it.
The proxy makes the request to that site, gets the response, adds the Access-Control-Allow-Origin
response header and any other CORS headers needed, then passes that back to your requesting code. And that response with the Access-Control-Allow-Origin
header added is what the browser sees, so the browser lets your frontend code actually access the response.
So I am trying to pass in an object, to my Fetch which will disable CORS
You don’t want to do that. To be clear, when you say you want to “disable CORS” it seems you actually mean you want to disable the same-origin policy. CORS itself is actually a way to do that — CORS is a way to loosen the same-origin policy, not a way to restrict it.
But anyway, it’s true you can — in just your local environment — do things like give your browser runtime flags to disable security and run insecurely, or you can install a browser extension locally to get around the same-origin policy, but all that does is change the situation just for you locally.
No matter what you change locally, anybody else trying to use your app is still going to run into the same-origin policy, and there’s no way you can disable that for other users of your app.
You most likely never want to use mode: 'no-cors'
in practice except in a few limited cases, and even then only if you know exactly what you’re doing and what the effects are. That’s because what setting mode: 'no-cors'
actually says to the browser is, “Block my frontend JavaScript code from looking into the contents of the response body and headers under all circumstances.” In most cases that’s obviously really not what you want.
As far as the cases when you would want to consider using mode: 'no-cors'
, see the answer at What limitations apply to opaque responses? for the details. The gist of it is that the cases are:
In the limited case when you’re using JavaScript to put content from another origin into a <script>
, <link rel=stylesheet>
, <img>
, <video>
, <audio>
, <object>
, <embed>
, or <iframe>
element (which works because embedding of resources cross-origin is allowed for those) — but for some reason you don’t want to or can’t do that just by having the markup of the document use the resource URL as the href
or src
attribute for the element.
When the only thing you want to do with a resource is to cache it. As alluded to in the answer What limitations apply to opaque responses?, in practice the scenario that applies to is when you’re using Service Workers, in which case the API that’s relevant is the Cache Storage API.
But even in those limited cases, there are some important gotchas to be aware of; see the answer at What limitations apply to opaque responses? for the details.
I have also tried to pass in the object
{ mode: 'opaque'}
There is no mode: 'opaque'
request mode — opaque
is instead just a property of the response, and browsers set that opaque property on responses from requests sent with the no-cors
mode.
But incidentally the word opaque is a pretty explicit signal about the nature of the response you end up with: “opaque” means you can’t see it.
You can execute commands in parallel with start
like this:
start "" ping myserver
start "" nslookup myserver
start "" morecommands
They will each start in their own command prompt and allow you to run multiple commands at the same time from one batch file.
Hope this helps!
Default file format is Parquet with spark.read.. and file reading csv that why you are getting the exception. Specify csv format with api you are trying to use
To add on to the answers above, here is a code sample
struct Test
{
int something;
}
struct NullableTest
{
int something;
}
class Example
{
public void Demo()
{
Test t = new Test();
t = null;
NullableTest? t2 = new NullableTest();
t2 = null;
}
}
This would give a compilation error:
Error 12 Cannot convert null to 'Test' because it is a non-nullable value type
Notice that there is no compilation error for NullableTest. (note the ? in the declaration of t2)
You can do it with the code you have, you just need to ensure that html
and body
are set to 100% height.
Demo: http://jsfiddle.net/kevinPHPkevin/a7eGN/
html, body {
height:100%;
}
body {
background-color: white;
background-image: url('http://www.canvaz.com/portrait/charcoal-1.jpg');
background-size: auto 100%;
background-repeat: no-repeat;
background-position: left top;
}
This type is defined in the C header <stdint.h>
which is part of the C++11 standard but not standard in C++03. According to the Wikipedia page on the header, it hasn't shipped with Visual Studio until VS2010.
In the meantime, you could probably fake up your own version of the header by adding typedef
s that map Microsoft's custom integer types to the types expected by C. For example:
typedef __int32 int32_t;
typedef unsigned __int32 uint32_t;
/* ... etc. ... */
Hope this helps!
Add permission in AndroidManifest.xml
, as given below
<uses-permission android:name="android.permission.WAKE_LOCK" />
preferably BEFORE your <application>
declaration tags but AFTER the <manifest>
tags, afterwards, try making your onCreate()
method contain only the WakeLock instantiation.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
PowerManager pm = (PowerManager)getSystemService(Context.POWER_SERVICE);
mWakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK | PowerManager.ON_AFTER_RELEASE, "My Tag");
}
and then in your onResume()
method place
@Override
public void onResume() {
mWakeLock.aquire();
}
and in your onFinish()
method place
@Override
public void onFinish() {
mWakeLock.release();
}
Well... It's kinda old. But still deserves a good answer.
And the good one is You Don't Wanna Touch The Default Python On Mac.
Install any Python version you need via Homebrew or whatever and use it in virtualenv. Virtualenv is often considered to be something crap-like, but it's still way, wayyyy better than changing python version system-wide (macOS is likely to protect itself from such actions) or user-wide, bash-wide... whatever. Just forget about the default Python. Using playgrounds like venv is what your OS will be most, very most grateful for.
The case is, for example, many modern Linux distributions get rid of Python2 installed out-of-the-box, leaving only Python3 in the system. But everytime you try to install something old with python2 as a dependency... hope you understand what I mean. A good developer doesn't care. Good developers create clean playgrounds with python version they desire.
If you're using jQueryUI - there is an onDrag event. If you're not, then attach your listener to mouseup(), not click().
It sounds like the application isn't signed. Download ldid from Cydia and then use it like so: ldid -S /Applications/AccelerometerGraph.app/AccelerometerGraph
Also be sure that the binary is marked as executable: chmod +x /Applications/AccelerometerGraph.app/AccelerometerGraph

I use Jquery for this
function setSizes() {
var containerHeight = $("#listContainer").height();
$("#myList").height(containerHeight - 18);

then I bind the window resize to recalc it whenever the browser window is resized (if container's size changed with window resize)
$(window).resize(function() { setSizes(); });
Just one line:
int value = Integer.parseInt(string.replaceAll("[^0-9]", ""));
I am a beginner to screen but I find it immensely useful while restoring lost connections. Your question has already been answered but this information might serve as an add on - I use putty with putty connection manager and name my screens - "tab1", "tab2", etc. - as for me the overall picture of the 8-10 tabs is more important than each individual tab name. I use the 8th tab for connecting to db, the 7th for viewing logs, etc. So when I want to reattach my screens I have written a simple wrapper which says:
#!/bin/bash
screen -d -r tab$1
where first argument is the tab number.
The "BIGINT(20)" specification isn't a digit limit. It just means that when the data is displayed, if it uses less than 20 digits it will be left-padded with zeros. 2^64 is the hard limit for the BIGINT type, and has 20 digits itself, hence BIGINT(20) just means everything less than 10^20 will be left-padded with spaces on display.
I used to do this using xxd
echo -n 5a | xxd -r -p
But then I realised that in Debian/Ubuntu, xxd is part of vim-common and hence might not be present in a minimal system. To also avoid perl (imho also not part of a minimal system) I ended up using sed, xargs and printf like this:
echo -n 5a | sed 's/\([0-9A-F]\{2\}\)/\\\\\\x\1/gI' | xargs printf
Mostly I only want to convert a few bytes and it's okay for such tasks. The advantage of this solution over the one of ghostdog74 is, that this can convert hex strings of arbitrary lengths automatically. xargs is used because printf doesnt read from standard input.
I have modified the UILabel by following code:
label.font=[label.font fontWithSize:25];
Try this and see whether is it working in your case or not???
If you are using data.table
then tstrsplit()
is a natural choice:
tstrsplit(string, ":")[[2]]
[1] "E001" "E002" "E003"
This worked for me.
You need to run it twice once for globals followed by locals
for name in dir():
if not name.startswith('_'):
del globals()[name]
for name in dir():
if not name.startswith('_'):
del locals()[name]
You could have is_hammer
in terms of row["Open"]
etc. as follows
def is_hammer(rOpen,rLow,rClose,rHigh):
return lower_wick_at_least_twice_real_body(rOpen,rLow,rClose) \
and closed_in_top_half_of_range(rHigh,rLow,rClose)
Then you can use map:
df["isHammer"] = map(is_hammer, df["Open"], df["Low"], df["Close"], df["High"])
Another way to create an array with String apart from
String[] strings = { "abc", "def", "hij", "xyz" };
is to use split. I find this more readable if there are lots of Strings.
String[] strings = "abc,def,hij,xyz".split(",");
or the following is good if you are parsing lines of strings from another source.
String[] strings = ("abc\n" +
"def\n" +
"hij\n" +
"xyz").split("\n");
return false;
at the end of the onclick handler will do the job. However, it's be better to simply add type="button"
to the <button>
- that way it behaves properly even without any JavaScript.
There are a few ways to handle that; Vanilla JavaScript can do it quite nicely:
function code(e) {
e = e || window.event;
return(e.keyCode || e.which);
}
window.onload = function(){
document.onkeypress = function(e){
var key = code(e);
// do something with key
};
};
Or a more structured way of handling it:
(function(d){
var modern = (d.addEventListener), event = function(obj, evt, fn){
if(modern) {
obj.addEventListener(evt, fn, false);
} else {
obj.attachEvent("on" + evt, fn);
}
}, code = function(e){
e = e || window.event;
return(e.keyCode || e.which);
}, init = function(){
event(d, "keypress", function(e){
var key = code(e);
// do stuff with key here
});
};
if(modern) {
d.addEventListener("DOMContentLoaded", init, false);
} else {
d.attachEvent("onreadystatechange", function(){
if(d.readyState === "complete") {
init();
}
});
}
})(document);
The following worked for me in with iOS 13.6 and Xcode 11.6 with a UITableViewController
that was embedded in a UINavigationController
:
override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
nil
}
override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
.zero
}
No other trickery needed. The override
keywords aren't needed when not using a UITableViewController
(i.e. when just implemented the UITableViewDelegate
methods). Of course if the goal was to hide just the first section's header, then this logic could be wrapped in a conditional as such:
override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
if section == 0 {
return nil
} else {
// Return some other view...
}
}
override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
if section == 0 {
return .zero
} else {
// Return some other height...
}
}
Lets see, numeric (3,2). That means you have 3 places for data and two of them are to the right of the decimal leaving only one to the left of the decimal. 15 has two places to the left of the decimal. BTW if you might have 100 as a value I'd increase that to numeric (5, 2)
swift enforces you to initialise every member var before it is ever/might ever be used. Since it can't be sure what happens when it is supers turn, it errors out: better safe than sorry
If you want a generic function you can use the following. Although it doesn't seem to be documented anywhere.
class CallbackTest {
myCallback: Function;

I've read through all the answers and I'd like to add one more that I think wins out because of its simplicity. Unlike the accepted answer this does not require recursion. It also does not require referencing a FileSystemObject.
Function FileNameFromPath(strFullPath As String) As String

An AnyCPU assembly will JIT to 64-bit code when loaded into a 64-bit process and 32 bit when loaded into a 32-bit process.
By limiting the CPU you would be saying: There is something being used by the assembly (something likely unmanaged) that requires 32 bits or 64 bits.
From the JDK source:
static <T> Function<T, T> identity() {
return t -> t;
}
So, no, as long as it is syntactically correct.
I made this work in this way:
<button class="btn" ng-click='toggleClass($event)'>button one</button>
<button class="btn" ng-click='toggleClass($event)'>button two</button>
in your controller:
$scope.toggleClass = function (event) {
$(event.target).toggleClass('active');
}
If you're dealing with Data Validation lists, you can use the Worksheet_Change event. Right click on the sheet with the data validation and choose View Code. Then type in this:
Private Sub Worksheet_Change(ByVal Target As Range)
MsgBox Target.Value
End Sub
If you're dealing with ActiveX comboboxes, it's a little more complicated. You need to create a custom class module to hook up the events. First, create a class module named CComboEvent and put this code in it.
Public WithEvents Cbx As MSForms.ComboBox
Private Sub Cbx_Change()
MsgBox Cbx.Value
End Sub
Next, create another class module named CComboEvents. This will hold all of our CComboEvent instances and keep them in scope. Put this code in CComboEvents.
Private mcolComboEvents As Collection
Private Sub Class_Initialize()
Set mcolComboEvents = New Collection
End Sub
Private Sub Class_Terminate()
Set mcolComboEvents = Nothing
End Sub
Public Sub Add(clsComboEvent As CComboEvent)
mcolComboEvents.Add clsComboEvent, clsComboEvent.Cbx.Name
End Sub
Finally, create a standard module (not a class module). You'll need code to put all of your comboboxes into the class modules. You might put this in an Auto_Open procedure so it happens whenever the workbook is opened, but that's up to you.
You'll need a Public variable to hold an instance of CComboEvents. Making it Public will kepp it, and all of its children, in scope. You need them in scope so that the events are triggered. In the procedure, loop through all of the comboboxes, creating a new CComboEvent instance for each one, and adding that to CComboEvents.
Public gclsComboEvents As CComboEvents
Public Sub AddCombox()
Dim oleo As OLEObject
Dim clsComboEvent As CComboEvent
Set gclsComboEvents = New CComboEvents
For Each oleo In Sheet1.OLEObjects
If TypeName(oleo.Object) = "ComboBox" Then
Set clsComboEvent = New CComboEvent
Set clsComboEvent.Cbx = oleo.Object
gclsComboEvents.Add clsComboEvent
End If
Next oleo
End Sub
Now, whenever a combobox is changed, the event will fire and, in this example, a message box will show.
You can see an example at https://www.dropbox.com/s/sfj4kyzolfy03qe/ComboboxEvents.xlsm
I've been struggling with this for days, checking/trying all the solutions, but my problem was I didn't call session_start();
again after the redirect. I just assumed the session was 'still alive'.
So don't forget that!
Use the following syntax to check if the element actually exists using jQuery.
let oElement = $(".myElementClass");
if(oElement[0]) {
// Do some jQuery operation here using oElement
}
else {
// Unable to fetch the object
}
To allow a nullable Amount
field, just use the null coalescing operator to convert nulls to 0.
var creditsSum = (from u in context.User
join ch in context.CreditHistory on u.ID equals ch.UserID
where u.ID == userID
select ch.Amount ?? 0).Sum();
If you need to frequently use LIKE, you can simplify the problem a bit. A custom method like () can be created in the model that inherits the Eloquent ORM:
public function scopeLike($query, $field, $value){
return $query->where($field, 'LIKE', "%$value%");
}
So then you can use this method in such way:
User::like('name', 'Tomas')->get();
I was facing a similar problem when starting up the application (using Spring Boot) with the database server down.
Hibernate can determine the correct dialect to use automatically, but in order to do this, it needs a live connection to the database.
The same error is produced in MariaDB (10.1.36-MariaDB) by using the combination of parenthesis and the COLLATE statement. My SQL was different, the error was the same, I had:
SELECT *
FROM table1
WHERE (field = 'STRING') COLLATE utf8_bin;
Omitting the parenthesis was solving it for me.
SELECT *
FROM table1
WHERE field = 'STRING' COLLATE utf8_bin;
No, not in the current one. But you can take a look at the next version by downloading it from github. It has vertical pills and tabs. Maybe that will help? (be aware, it's under construction tho)
NAudio wraps the WaveOutXXXX API. I haven't looked at the source, but if NAudio exposes the waveOutWrite() function in a way that doesn't automatically stop playback on each call, then you should be able to do what you really want, which is to start playing the audio stream before you've received all the data.
Using the waveOutWrite() function allows you to "read ahead" and dump smaller chunks of audio into the output queue - Windows will automatically play the chunks seamlessly. Your code would have to take the compressed audio stream and convert it to small chunks of WAV audio on the fly; this part would be really difficult - all the libraries and components I've ever seen do MP3-to-WAV conversion an entire file at a time. Probably your only realistic chance is to do this using WMA instead of MP3, because you can write simple C# wrappers around the multimedia SDK.
This is the variable for the current value in the pipe line, which is called $PSItem
in Powershell 3 and newer.
1,2,3 | %{ write-host $_ }
or
1,2,3 | %{ write-host $PSItem }
For example in the above code the %{}
block is called for every value in the array. The $_
or $PSItem
variable will contain the current value.

Using presence one can do
class Task < ActiveRecord::Base
before_save :default_values
def default_values
self.status = status.presence || 'P'

My issue was a sconscript did not have the cpp
file defined in it. This can be very confusing because Visual Studio has the cpp
file in the project but something else entirely is building.
I solved in this way: I logged in with root username
mysql -u root -p -h localhost
I created a new user with
CREATE USER 'francesco'@'localhost' IDENTIFIED BY 'some_pass';
then I created the database
CREATE DATABASE shop;
I granted privileges for new user for this database
GRANT ALL PRIVILEGES ON shop.* TO 'francesco'@'localhost';
Then I logged out root and logged in new user
quit;
mysql -u francesco -p -h localhost
I rebuilt my database using a script
source shop.sql;
And that's it.. Now from php works without problems with the call
$conn = new mysqli("localhost", "francesco", "some_pass", "shop");
Thanks to all for your time :)
A simple pure-Python implementation would be:
import math
import re
from collections import Counter
WORD = re.compile(r"\w+")
def get_cosine(vec1, vec2):
intersection = set(vec1.keys()) & set(vec2.keys())
numerator = sum([vec1[x] * vec2[x] for x in intersection])
sum1 = sum([vec1[x] ** 2 for x in list(vec1.keys())])
sum2 = sum([vec2[x] ** 2 for x in list(vec2.keys())])
denominator = math.sqrt(sum1) * math.sqrt(sum2)
if not denominator:
return 0.0
else:
return float(numerator) / denominator
def text_to_vector(text):
words = WORD.findall(text)
return Counter(words)
text1 = "This is a foo bar sentence ."
text2 = "This sentence is similar to a foo bar sentence ."
vector1 = text_to_vector(text1)
vector2 = text_to_vector(text2)
cosine = get_cosine(vector1, vector2)
print("Cosine:", cosine)
Prints:
Cosine: 0.861640436855
The cosine formula used here is described here.
This does not include weighting of the words by tf-idf, but in order to use tf-idf, you need to have a reasonably large corpus from which to estimate tfidf weights.
You can also develop it further, by using a more sophisticated way to extract words from a piece of text, stem or lemmatise it, etc.
One workaround is to write .ToList().ForEach(x => ...)
.
pros
Easy to understand - reader only needs to know what ships with C#, not any additional extension methods.
Syntactic noise is very mild (only adds a little extranious code).
Doesn't usually cost extra memory, since a native .ForEach()
would have to realize the whole collection, anyway.
cons
Order of operations isn't ideal. I'd rather realize one element, then act on it, then repeat. This code realizes all elements first, then acts on them each in sequence.
If realizing the list throws an exception, you never get to act on a single element.
If the enumeration is infinite (like the natural numbers), you're out of luck.
In the first case with
set encoding=utf-8
, you'll change the output encoding that is shown in the terminal.In the second case with
set fileencoding=utf-8
, you'll change the output encoding of the file that is written.
As stated by @Dennis, you can set them both in your ~/.vimrc if you always want to work in utf-8
.
From the wiki of VIM about working with unicode
"encoding
sets how vim shall represent characters internally. Utf-8 is necessary for most flavors of Unicode."
"fileencoding
sets the encoding for a particular file (local to buffer); :setglobal sets the default value. An empty value can also be used: it defaults to same as 'encoding'. Or you may want to set one of the ucs encodings, It might make the same disk file bigger or smaller depending on your particular mix of characters. Also, IIUC, utf-8 is always big-endian (high bit first) while ucs can be big-endian or little-endian, so if you use it, you will probably need to set 'bomb" (see below)."
You can make it works with a Middleware class. Let me give you an idea.
namespace MyApp\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\App;
class HttpsProtocol {
public function handle($request, Closure $next)
{
if (!$request->secure() && App::environment() === 'production') {
return redirect()->secure($request->getRequestUri());
}
return $next($request);
}
}
Then, apply this middleware to every request adding setting the rule at Kernel.php
file, like so:
protected $middleware = [
'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
'Illuminate\Cookie\Middleware\EncryptCookies',
'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
'Illuminate\Session\Middleware\StartSession',
'Illuminate\View\Middleware\ShareErrorsFromSession',
// appending custom middleware
'MyApp\Http\Middleware\HttpsProtocol'
];
At sample above, the middleware will redirect every request to https if:
production
. So, just adjust the settings according to your preferences. I am using this code in production environment with a WildCard SSL and the code works correctly. If I remove && App::environment() === 'production'
and test it in localhost, the redirection also works. So, having or not a installed SSL is not the problem. Looks like you need to keep a very hard attention to your Cloudflare layer in order to get redirected to Https protocol.
Thanks to @Adam Link
's suggestion: it is likely caused by the headers that Cloudflare is passing. CloudFlare likely hits your server via HTTP and passes a X-Forwarded-Proto header that declares it is forwarding a HTTPS request. You need add another line in your Middleware that say...
$request->setTrustedProxies( [ $request->getClientIp() ] );
...to trust the headers CloudFlare is sending. This will stop the redirect loop
Just need to add the middleware class into web
group in kernel.php file
:
protected $middlewareGroups = [
'web' => [
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
// here
\MyApp\Http\Middleware\HttpsProtocol::class
],
];
Remember that
web
group is applied to every route by default, so you do not need to setweb
explicitly in routes nor controllers.
App::environment() === 'production'
. For previous version was
env('APP_ENV') === 'production'
.\URL::forceScheme('https');
actually does not redirect. It just builds links with https://
once the website is rendered.There is a way to skip the errors inside the code and go on with the loop anyway, hope it helps:
Sub new1()
Dim wsFunc As WorksheetFunction: Set wsFunc = Application.WorksheetFunction
Dim ws As Worksheet: Set ws = Sheets(1)
Dim rngLook As Range: Set rngLook = ws.Range("A:M")
currName = "Example"
On Error Resume Next ''if error, the code will go on anyway
cellNum = wsFunc.VLookup(currName, rngLook, 13, 0)
If Err.Number <> 0 Then
''error appeared
MsgBox "currName not found" ''optional, no need to do anything
End If
On Error GoTo 0 ''no error, coming back to default conditions
End Sub
Super simple:
Press the F5 key and the code will run.
If a breakpoint is set, pressing F5 will stop at the breakpoint and run the code in debug mode.
Other Method - To add Shortcut
Note: You must have Python Extension By Microsoft installed in Visual Studio Code, and the Python interpreter selected in the lower-left corner.
Go to File ? Preferences ? Keyboard Shortcuts (alternatively, you can press Ctrl + K + S) In the search box, enter python.execInTerminal Double click that result (alternatively, you can click the plus icon) Press Ctrl + Alt + B to register this as the keybinding (alternatively, you can enter your own keybinding)
Now you can close the Keyboard Shortcuts tab Go to the Python file you want to run and press Ctrl + Alt + B (alternatively, you can press the keybinding you set) to run it. The output will be shown in the bottom terminal tab.
If you want to delete one item
wishlist = Wishlist.objects.get(id = 20)
wishlist.delete()
If you want to delete all items in Wishlist for example
Wishlist.objects.all().delete()

git checkout -b NEW_BRANCH_NAME COMMIT_ID
This will create a new branch called 'NEW_BRANCH_NAME' and check it out.
("check out" means "to switch to the branch")
git branch NEW_BRANCH_NAME COMMIT_ID
This just creates the new branch without checking it out.
in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:
git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME
System.out.printf("I %n am %n a %n boy");
I
am
a
boy
It's better to use %n
as an OS independent new-line character instead of \n
and it's easier than using System.lineSeparator()
Why to use %n
, because on each OS, new line refers to a different set of character(s);
Unix and modern Mac's : LF (\n)
Windows : CR LF (\r\n)
Older Macintosh Systems : CR (\r)
LF is the acronym of Line Feed and CR is the acronym of Carriage Return. The escape characters are written inside the parenthesis. So on each OS, new line stands for something specific to the system. %n
is OS agnostic, it is portable. It stands for \n
on Unix systems or \r\n
on Windows systems and so on. Thus, Do not use \n
, instead use %n
.
Examples where seek is the size of the file you want in bytes
#kilobytes
dd if=/dev/zero of=filename bs=1 count=0 seek=200K
#megabytes
dd if=/dev/zero of=filename bs=1 count=0 seek=200M
#gigabytes
dd if=/dev/zero of=filename bs=1 count=0 seek=200G
#terabytes
dd if=/dev/zero of=filename bs=1 count=0 seek=200T
From the dd manpage:
BLOCKS and BYTES may be followed by the following multiplicative suffixes: c=1, w=2, b=512, kB=1000, K=1024, MB=1000*1000, M=1024*1024, GB =1000*1000*1000, G=1024*1024*1024, and so on for T, P, E, Z, Y.
If you set CURLOPT_RETURNTRANSFER
to true
or 1
then the return value from curl_exec
will be the actual result from the successful operation. In other words it will not return TRUE
on success. Although it will return FALSE
on failure.
As described in the Return Values section of curl-exec
PHP manual page: http://php.net/manual/function.curl-exec.php
You should enable the CURLOPT_FOLLOWLOCATION
option for redirects but this would be a problem if your server is in safe_mode
and/or open_basedir
is in effect which can cause issues with curl as well.
You have
COPY files/* /test/
which expands toCOPY files/dir files/file1 files/file2 files/file /test/
.
If you split this up into individualCOPY
commands (e.g.COPY files/dir /test/
) you'll see that (for better or worse)COPY
will copy the contents of each argdir
into the destination directory. Not the argdir
itself, but the contents.I'm not thrilled with that fact that COPY doesn't preserve the top-level dir but its been that way for a while now.
so in the name of preserving a backward compatibility, it is not possible to COPY
/ADD
a directory structure.
The only workaround would be a series of RUN mkdir -p /x/y/z
to build the target directory structure, followed by a series of docker ADD
(one for each folder to fill).
(ADD
, not COPY
, as per comments)
In your Execute SQL Task, make sure SQLSourceType is set to Direct Input, then your SQL Statement is the name of the stored proc, with questionmarks for each paramter of the proc, like so:
Click the parameter mapping in the left column and add each paramter from your stored proc and map it to your SSIS variable:
Now when this task runs it will pass the SSIS variables to the stored proc.
If you are running kafka on local machine, try updating $KAFKA_DIR/config/server.properties with below line:
listeners=PLAINTEXT://localhost:9092
and then restarting kafka.
Detecting a loop in a linked list can be done in one of the simplest ways, which results in O(N) complexity using hashmap or O(NlogN) using a sort based approach.
As you traverse the list starting from head, create a sorted list of addresses. When you insert a new address, check if the address is already there in the sorted list, which takes O(logN) complexity.
Firstly you need to add a where T:class
constraint - you can't call GetValue
on value types unless they're passed by ref
.
Secondly GetValue
is very slow and gets called a lot.
To get round this we can create a delegate and call that instead:
MethodInfo method = property.GetGetMethod(true);
Delegate.CreateDelegate(typeof(Func<TClass, TProperty>), method );
The problem is that we don't know TProperty
, but as usual on here Jon Skeet has the answer - we can use reflection to retrieve the getter delegate, but once we have it we don't need to reflect again:
public class ReflectionUtility
{
internal static Func<object, object> GetGetter(PropertyInfo property)
{
// get the get method for the property
MethodInfo method = property.GetGetMethod(true);
// get the generic get-method generator (ReflectionUtility.GetSetterHelper<TTarget, TValue>)
MethodInfo genericHelper = typeof(ReflectionUtility).GetMethod(
"GetGetterHelper",
BindingFlags.Static | BindingFlags.NonPublic);
// reflection call to the generic get-method generator to generate the type arguments
MethodInfo constructedHelper = genericHelper.MakeGenericMethod(
method.DeclaringType,
method.ReturnType);
// now call it. The null argument is because it's a static method.
object ret = constructedHelper.Invoke(null, new object[] { method });
// cast the result to the action delegate and return it
return (Func<object, object>) ret;
}
static Func<object, object> GetGetterHelper<TTarget, TResult>(MethodInfo method)
where TTarget : class // target must be a class as property sets on structs need a ref param
{
// Convert the slow MethodInfo into a fast, strongly typed, open delegate
Func<TTarget, TResult> func = (Func<TTarget, TResult>) Delegate.CreateDelegate(typeof(Func<TTarget, TResult>), method);
// Now create a more weakly typed delegate which will call the strongly typed one
Func<object, object> ret = (object target) => (TResult) func((TTarget) target);
return ret;
}
}
So now your method becomes:
public static DataTable ToDataTable<T>(this IEnumerable<T> items)
where T: class
{
// ... create table the same way
var propGetters = new List<Func<T, object>>();
foreach (var prop in props)
{
Func<T, object> func = (Func<T, object>) ReflectionUtility.GetGetter(prop);
propGetters.Add(func);
}
// Add the property values per T as rows to the datatable
foreach (var item in items)
{
var values = new object[props.Length];
for (var i = 0; i < props.Length; i++)
{
//values[i] = props[i].GetValue(item, null);
values[i] = propGetters[i](item);
}
table.Rows.Add(values);
}
return table;
}
You could further optimise it by storing the getters for each type in a static dictionary, then you will only have the reflection overhead once for each type.
How about redis-cli get KEYNAME | wc -c
from child component to parent component as below
parent component
class Parent extends React.Component {
state = { message: "parent message" }
callbackFunction = (childData) => {
this.setState({message: childData})
},
render() {
return (
<div>
<Child parentCallback = {this.callbackFunction}/>
<p> {this.state.message} </p>
</div>
);
}
}
child component
class Child extends React.Component{
sendBackData = () => {
this.props.parentCallback("child message");
},
render() {
<button onClick={sendBackData}>click me to send back</button>
}
};
I hope this work
I use something like this function I created...
Object.getKeys = function(obj, add) {
if(obj === undefined || obj === null) {
return undefined;
}
var keys = [];
if(add !== undefined) {
keys = jQuery.merge(keys, add);
}
for(key in obj) {
if(obj.hasOwnProperty(key)) {
keys.push(key);
}
}
return keys;
};
I think you could set obj to self or something better in the first test. It seems sometimes I'm checking if it's empty too so I did it that way. Also I don't think {} is Object.* or at least there's a problem finding the function getKeys on the Object that way. Maybe you're suppose to put prototype first, but that seems to cause a conflict with GreenSock etc.
I was having trouble getting redirection to HTTPS to work on a Windows server which runs version 6 of MS Internet Information Services (IIS). I’m more used to working with Apache on a Linux host so I turned to the Internet for help and this was the highest ranking Stack Overflow question when I searched for “php redirect http to https”. However, the selected answer didn’t work for me.
After some trial and error, I discovered that with IIS, $_SERVER['HTTPS']
is
set to off
for non-TLS connections. I thought the following code should
help any other IIS users who come to this question via search engine.
<?php
if (! isset($_SERVER['HTTPS']) or $_SERVER['HTTPS'] == 'off' ) {
$redirect_url = "https://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
header("Location: $redirect_url");
exit();
}
?>
Edit: From another Stack Overflow answer,
a simpler solution is to check if($_SERVER["HTTPS"] != "on")
.
This XPath is specific to the code snippet you've provided. To select <child>
with id as #grand
you can write //child[@id='#grand']
.
To get age //child[@id='#grand']/@age
Hope this helps
awk 'BEGIN {FS=" "} {printf "\047%s\047 ", $1}'
$('input[type=button]' ).click(function() {
var bid = jQuery(this).attr('id'); // button ID
var trid = $(this).parents('tr:first').attr('id'); // table row ID
});
Yup, this is possible of course. Here are several examples.
-- one way to do this
DECLARE @Cnt int
SELECT @Cnt = COUNT(SomeColumn)
FROM TableName
GROUP BY SomeColumn
-- another way to do the same thing
DECLARE @StreetName nvarchar(100)
SET @StreetName = (SELECT Street_Name from Streets where Street_ID = 123)
-- Assign values to several variables at once
DECLARE @val1 nvarchar(20)
DECLARE @val2 int
DECLARE @val3 datetime
DECLARE @val4 uniqueidentifier
DECLARE @val5 double
SELECT @val1 = TextColumn,
@val2 = IntColumn,
@val3 = DateColumn,
@val4 = GuidColumn,
@val5 = DoubleColumn
FROM SomeTable
May be you can use the attribute xml:space="preserve" for preserving whitespace in the source XAML
<TextBlock xml:space="preserve">
Stuff on line 1

It's not too late for the newcomers.
plt.axvline(x, color='r')
It takes the range of y as well, using ymin and ymax.
Alternative log-in using PuTTY. Its good but needs a few steps.

Just point to any View
inside the Activity's
XML. You can give an id to the root viewGroup, for example, and use:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
View parentLayout = findViewById(android.R.id.content);
Snackbar.make(parentLayout, "This is main activity", Snackbar.LENGTH_LONG)
.setAction("CLOSE", new View.OnClickListener() {
@Override
public void onClick(View view) {
}
})
.setActionTextColor(getResources().getColor(android.R.color.holo_red_light ))
.show();
//Other stuff in OnCreate();
}
Not sure if this will help in your context...
Can the soap object be cast as a BindingProvider ?
MyWebServiceSoap soap;
MyWebService service = new MyWebService("http://www.google.com");
soap = service.getMyWebServiceSoap();
// set timeouts here
((BindingProvider)soap).getRequestContext().put("com.sun.xml.internal.ws.request.timeout", 10000);
soap.sendRequestToMyWebService();
On the other hand if you are wanting to set the timeout on the initialization of the MyWebService object then this will not help.
This worked for me when wanting to timeout the individual WebService calls.
I'm using Angular 6. I followed Mav55's answer and it worked. However I wanted to make sure if fixture.detectChanges();
was really necessary so I removed it and it still worked. Then I removed tick();
to see if it worked and it did. Finally I removed the test from the fakeAsync()
wrap, and surprise, it worked.
So I ended up with this:
it('should call onClick method', () => {
const onClickMock = spyOn(component, 'onClick');
fixture.debugElement.query(By.css('button')).triggerEventHandler('click', null);
expect(onClickMock).toHaveBeenCalled();
});
And it worked just fine.
Here's how I do it:
Code:
let fs = require('fs');
let path = require('path');
let myController = (req, res) => {
let filename = 'myFile.ext';
let absPath = path.join(__dirname, '/my_files/', filename);
let relPath = path.join('./my_files', filename); // path relative to server root
fs.writeFile(relPath, 'File content', (err) => {
if (err) {
console.log(err);
}
res.download(absPath, (err) => {
if (err) {
console.log(err);
}
fs.unlink(relPath, (err) => {
if (err) {
console.log(err);
}
console.log('FILE [' + filename + '] REMOVED!');
});
});
});
};
On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.

You don't need to wrap it in a list with [..]
, just provide the subselection of the columns index:
df.drop(df.columns[[1, 69]], axis=1, inplace=True)
as the index object is already regarded as list-like.
My case is the page is sending multiple requests with different parameters when it was open. So most are being "stalled". Following requests immediately sent gets "stalled". Avoiding unnecessary requests would be better (to be lazy...).
Although the provided answers do work for a specific module, they won't reload submodules, as noted in This answer:
If a module imports objects from another module using
from ... import ...
, callingreload()
for the other module does not redefine the objects imported from it — one way around this is to re-execute the from statement, another is to useimport
and qualified names (module.*name*
) instead.
However, if using the __all__
variable to define the public API, it is possible to automatically reload all publicly available modules:
# Python >= 3.5
import importlib
import types
def walk_reload(module: types.ModuleType) -> None:
if hasattr(module, "__all__"):
for submodule_name in module.__all__:
walk_reload(getattr(module, submodule_name))
importlib.reload(module)
walk_reload(my_module)
The caveats noted in the previous answer are still valid though. Notably, modifying a submodule that is not part of the public API as described by the __all__
variable won't be affected by a reload using this function. Similarly, removing an element of a submodule won't be reflected by a reload.

The Most Reliable way to replay har file is using a free tool like Fiddler, the tool is always free and can be downloaded quickly. The sites for the opening har file are all buggy and cannot open large files. Fiddler is available for all platforms.
https://www.telerik.com/download/fiddler
Go to File Menu -> Import Sessions...
Select the "HTTPArchive" Option
Browse to your HAR file
The HAR file will open and replay on the fiddler window.
Check this
String[] VALUES = new String[] {"AB","BC","CD","AE"};
String s;
for(int i=0; i< VALUES.length ; i++)

}
else{
//do your stuff

Also this problem may occur if you're using HTTP GET

Since I cant comment yet im gonna post as an answer the link.. I have found a simple, well organized tutorial on recyclerview http://www.androiddeft.com/2017/10/01/recyclerview-android/
Apart from that when you are going to add a recycler view into you activity what you want to do is as below and how you should do this has been described on the link
How about:
DELETE guide_category
WHERE id_guide_category IN (
SELECT id_guide_category
FROM guide_category AS gc
LEFT JOIN guide AS g
ON g.id_guide = gc.id_guide
WHERE g.title IS NULL

You need to use a global regular expression for this. Try it this way:
str.replace(/"/g, '\\"');
Check out regex syntax and options for the replace function in Using Regular Expressions with JavaScript.

In bootstrap 4, they have designed a bigger input file.
A simple solution to increase the size input file is to use font-size
:
Add you style, for example:
input[type="file"] {
font-size:35px
}
Otherwise, you can make one custom class and add to input control.
synchronized simple means no two threads can access the block/method simultaneously. When we say any block/method of a class is synchronized it means only one thread can access them at a time. Internally the thread which tries to access it first take a lock on that object and as long as this lock is not available no other thread can access any of the synchronized methods/blocks of that instance of the class.
Note another thread can access a method of the same object which is not defined to be synchronized. A thread can release the lock by calling
Object.wait()
I think ("\") may be causing the problem because \ is the escape character. change it to ("\\")
Some time ago Jupyter Notebooks started stripping JavaScript from HTML content [#3118]. Here are two solutions:
Serving Local HTML
If you want to embed an HTML page with JavaScript on your page now, the easiest thing to do is to save your HTML file to the directory with your notebook and then load the HTML as follows:
from IPython.display import IFrame
IFrame(src='./nice.html', width=700, height=600)
Serving Remote HTML
If you prefer a hosted solution, you can upload your HTML page to an Amazon Web Services "bucket" in S3, change the settings on that bucket so as to make the bucket host a static website, then use an Iframe component in your notebook:
from IPython.display import IFrame
IFrame(src='https://s3.amazonaws.com/duhaime/blog/visualizations/isolation-forests.html', width=700, height=600)
This will render your HTML content and JavaScript in an iframe, just like you can on any other web page:
<iframe src='https://s3.amazonaws.com/duhaime/blog/visualizations/isolation-forests.html', width=700, height=600></iframe>

Here is the best way to set your root password : Source Link Step 3 is working perfectly for me.
Commands for You
- sudo mysql
- SELECT user,authentication_string,plugin,host FROM mysql.user;
- ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
- FLUSH PRIVILEGES;
- SELECT user,authentication_string,plugin,host FROM mysql.user;
- exit
Now you can use the Password for the root user is 'password' :
- mysql -u root -p
- CREATE USER 'sammy'@'localhost' IDENTIFIED BY 'password';
- GRANT ALL PRIVILEGES ON . TO 'sammy'@'localhost' WITH GRANT OPTION;
- FLUSH PRIVILEGES;
- exit
Test your MySQL Service and Version:
systemctl status mysql.service
sudo mysqladmin -p -u root version
Two ways
1)instantiate the first class
and getter for arrayList
or
2)Make arraylist as static
And finally
Sometimes it's better to think like a parser, like T-SQL parser. While executing the statement, parser does not have any value in Pivot section and you can't have any check expression in that section. By the way, you can simply use this:
SELECT CLASS
, IsNull([AZ], 0)
, IsNull([CA], 0)
, IsNull([TX], 0)
FROM #TEMP
PIVOT (
SUM(DATA)
FOR STATE IN (
[AZ]
, [CA]
, [TX]
)
) AS PVT
ORDER BY CLASS

You can choose between the following two methods to set the text of an Entry
widget. For the examples, assume imported library import tkinter as tk
and root window root = tk.Tk()
.
Method A: Use delete
and insert
Widget Entry
provides methods delete
and insert
which can be used to set its text to a new value. First, you'll have to remove any former, old text from Entry
with delete
which needs the positions where to start and end the deletion. Since we want to remove the full old text, we start at 0
and end at wherever the end currently is. We can access that value via END
. Afterwards the Entry
is empty and we can insert new_text
at position 0
.
entry = tk.Entry(root)
new_text = "Example text"
entry.delete(0, tk.END)
entry.insert(0, new_text)
Method B: Use StringVar
You have to create a new StringVar
object called entry_text
in the example. Also, your Entry
widget has to be created with keyword argument textvariable
. Afterwards, every time you change entry_text
with set
, the text will automatically show up in the Entry
widget.
entry_text = tk.StringVar()
entry = tk.Entry(root, textvariable=entry_text)
new_text = "Example text"
entry_text.set(new_text)
Complete working example which contains both methods to set the text via Button
:
This window
is generated by the following complete working example:
import tkinter as tk
def button_1_click():
# define new text (you can modify this to your needs!)
new_text = "Button 1 clicked!"
# delete content from position 0 to end
entry.delete(0, tk.END)
# insert new_text at position 0
entry.insert(0, new_text)
def button_2_click():
# define new text (you can modify this to your needs!)
new_text = "Button 2 clicked!"
# set connected text variable to new_text
entry_text.set(new_text)
root = tk.Tk()
entry_text = tk.StringVar()
entry = tk.Entry(root, textvariable=entry_text)
button_1 = tk.Button(root, text="Button 1", command=button_1_click)
button_2 = tk.Button(root, text="Button 2", command=button_2_click)
entry.pack(side=tk.TOP)
button_1.pack(side=tk.LEFT)
button_2.pack(side=tk.LEFT)
root.mainloop()

Try this,
I think ,this is one of the simple solutions.
int rowIndex = table.Rows.IndexOf(table.Select("A = 'foo' AND B = 'bar' AND C = 'baz'")[0]);
string strD= Convert.ToString(table.Rows[rowIndex]["D"]);
Make sure,combination of values for column A, B and C is unique in the datatable.
In addition to what people wrote years ago:
main.c:30:3: warning: unknown conversion type character 'l' in format [-Wformat=]
printf("%llu\n", k);
Then your version of mingw does not default to c99. Add this compiler flag: -std=c99
.
Instead of a list of dictionaries as in ShikharDua's answer, we can also represent our table as a dictionary of lists, where each list stores one column in row-order, given we know our columns beforehand. At the end we construct our DataFrame once.
For c columns and n rows, this uses 1 dictionary and c lists, versus 1 list and n dictionaries. The list of dictionaries method has each dictionary storing all keys and requires creating a new dictionary for every row. Here we only append to lists, which is constant time and theoretically very fast.
# current data
data = {"Animal":["cow", "horse"], "Color":["blue", "red"]}
# adding a new row (be careful to ensure every column gets another value)
data["Animal"].append("mouse")
data["Color"].append("black")
# at the end, construct our DataFrame
df = pd.DataFrame(data)
# Animal Color
# 0 cow blue
# 1 horse red
# 2 mouse black
webpack users, add the below to your plugins
array.

Came across this looking for something else.
While the post looks fairly old, the easiest solution in bash is illustrated below (at least bash 4) using set -- "${@:#}"
where # is the starting number of the array element we want to preserve forward:
#!/bin/bash
someVar="${1}"
someOtherVar="${2}"
set -- "${@:3}"
input=${@}
[[ "${input[*],,}" == *"someword"* ]] && someNewVar="trigger"
echo -e "${someVar}\n${someOtherVar}\n${someNewVar}\n\n${@}"
Basically, the set -- "${@:3}"
just pops off the first two elements in the array like perl's shift and preserves all remaining elements including the third. I suspect there's a way to pop off the last elements as well.
After years of ugly string parsing, there's a better way: URLSearchParams Let's have a look at how we can use this new API to get values from the location!
//Assuming URL has "?post=1234&action=edit"
var urlParams = new URLSearchParams(window.location.search);
console.log(urlParams.has('post')); // true
console.log(urlParams.get('action')); // "edit"
console.log(urlParams.getAll('action')); // ["edit"]
console.log(urlParams.toString()); // "?post=1234&action=edit"
console.log(urlParams.append('active', '1')); // "?
post=1234&action=edit&active=1"
use this function from an answer below instead of URLSearchParams
$.urlParam = function (name) {
var results = new RegExp('[\?&]' + name + '=([^&#]*)')
.exec(window.location.search);
return (results !== null) ? results[1] || 0 : false;
}
console.log($.urlParam('action')); //edit

To access the tomcat manager from different machine you have to follow bellow steps:
1. Update conf/tomcat-users.xml file with user and some roles:
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status"/>
Here admin user is assigning roles="manager-gui,manager-script,manager-jmx,manager-status".
Here tomcat user and password is : admin
2. Update webapps/manager/META-INF/context.xml file (Allowing IP address):
Default configuration:
<Context antiResourceLocking="false" privileged="true" >
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
<Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>
Here in Valve it is allowing only local machine IP start with 127.\d+.\d+.\d+ .
2.a : Allow specefic IP:
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|YOUR.IP.ADDRESS.HERE" />
Here you just replace |YOUR.IP.ADDRESS.HERE with your IP address
2.b : Allow all IP:
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow=".*" />
Here using allow=".*" you are allowing all IP.
Thanks :)

Use gsub(..)
function for replacing the special character with apostrophe
I know it is an old question, but I was struggling finding the answer myself. Here is what I have come up with:
Python 3:
>>> num_dict = {'num': 0.123, 'num2': 0.127}
>>> "{0[num]:.2f}_{0[num2]:.2f}".format(num_dict)
0.12_0.13
For Windows Machines, use:
git reset HEAD~1 #Remove Commit Locally
>>> xs = [["A",0], ["B",1], ["C",0], ["D",2], ["E",2]]
>>> xs.sort(key=lambda x: x[1])
>>> reduce(lambda l, x: (l.append([x]) if l[-1][0][1] != x[1] else l[-1].append(x)) or l, xs[1:], [[xs[0]]]) if xs else []
[[['A', 0], ['C', 0]], [['B', 1]], [['D', 2], ['E', 2]]]
Basically, if the list is sorted, it is possible to reduce
by looking at the last group constructed by the previous steps - you can tell if you need to start a new group, or modify an existing group. The ... or l
bit is a trick that enables us to use lambda
in Python. (append
returns None
. It is always better to return something more useful than None
, but, alas, such is Python.)
Excel 2013 can do Count distinct in pivots. If no access to 2013, and it's a smaller amount of data, I make two copies of the raw data, and in copy b, select both columns and remove duplicates. Then make the pivot and count your column b.
This maybe not the answer to poster's question.But this may helpful to people whose face same situation with me:
The client have two network cards,a wireless one and a normal one.
The ping to server can be succeed.However telnet serverAddress 3306
would fail.
And would complain
Can't connect to MySQL server on 'xxx.xxx.xxx.xxx' (10060)
when try to connect to server.So I forbidden the normal network adapters.
And tried telnet serverAddress 3306
it works.And then it work when connect to MySQL server.
Just use "justify-content-center" in the row's class attribute.
<div class="container">

</div>
</div>
Outside of character classes, it is conventional not to escape hyphens. If I saw an escaped hyphen outside of a character class, that would suggest to me that it was written by someone who was not very comfortable with regexes.
Inside character classes, I don't think one way is conventional over the other; in my experience, it usually seems to be to put either first or last, as in [-._:]
or [._:-]
, to avoid the backslash; but I've also often seen it escaped instead, as in [._\-:]
, and I wouldn't call that unconventional.
SaaS: Software as a Service Cloud application services or “Software as a Service” (SaaS) are probably the most popular form of cloud computing and are easy to use. SaaS uses the Web to deliver applications that are managed by a third-party vendor and whose interface is accessed on the clients’ side. Most SaaS applications can be run directly from a Web browser, without any downloads or installations required. SaaS eliminates the need to install and run applications on individual computers. With SaaS, it’s easy for enterprises to streamline their maintenance and support, because everything can be managed by vendors: applications, runtime, data, middleware, O/S, virtualization, servers, storage, and networking. Gmail is one famous example of an SaaS mail provider.
PaaS: Platform as a Service The most complex of the three, cloud platform services or “Platform as a Service” (PaaS) deliver computational resources through a platform. What developers gain with PaaS is a framework they can build upon to develop or customize applications. PaaS makes the development, testing, and deployment of applications quick, simple, and cost-effective, eliminating the need to buy the underlying layers of hardware and software. One comparison between SaaS vs. PaaS has to do with what aspects must be managed by users, rather than providers: With PaaS, vendors still manage runtime, middleware, O/S, virtualization, servers, storage, and networking, but users manage applications and data.
IaaS: Infrastructure as a Service Cloud infrastructure services, known as “Infrastructure as a Service” (IaaS), deliver computer infrastructure (such as a platform virtualization environment), storage, and networking. Instead of having to purchase software, servers, or network equipment, users can buy these as a fully outsourced service that is usually billed according to the amount of resources consumed. Basically, in exchange for a rental fee, a third party allows you to install a virtual server on their IT infrastructure. Compared to SaaS and PaaS, IaaS users are responsible for managing more: applications, data, runtime, middleware, and O/S. Vendors still manage virtualization, servers, hard drives, storage, and networking. What users gain with IaaS is infrastructure on top of which they can install any required platforms. Users are responsible for updating these if new versions are released.
DC is your domain. If you want to connect to the domain example.com than your dc's are: DC=example,DC=com
You actually don't need any hostname or ip address of your domain controller (There could be plenty of them).
Just imagine that you're connecting to the domain itself. So for connecting to the domain example.com you can simply write
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
And you're done.
You can also specify a user and a password used to connect:
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com", "username", "password");
Also be sure to always write LDAP in upper case. I had some trouble and strange exceptions until I read somewhere that I should try to write it in upper case and that solved my problems.
The directoryEntry.Path
Property allows you to dive deeper into your domain. So if you want to search a user in a specific OU (Organizational Unit) you can set it there.
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
directoryEntry.Path = "LDAP://OU=Specific Users,OU=All Users,OU=Users,DC=example,DC=com";
This would match the following AD hierarchy:
Simply write the hierarchy from deepest to highest.
Now you can do plenty of things
For example search a user by account name and get the user's surname:
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
DirectorySearcher searcher = new DirectorySearcher(directoryEntry) {
PageSize = int.MaxValue,
Filter = "(&(objectCategory=person)(objectClass=user)(sAMAccountName=AnAccountName))"
};
searcher.PropertiesToLoad.Add("sn");
var result = searcher.FindOne();
if (result == null) {
return; // Or whatever you need to do in this case
}
string surname;
if (result.Properties.Contains("sn")) {
surname = result.Properties["sn"][0].ToString();
}
Consider this line of code:
Math.abs(firstDouble - secondDouble) < Double.MIN_NORMAL
It returns whether firstDouble is equal to secondDouble. I'm unsure as to whether or not this would work in your exact case (as Kevin pointed out, performing any math on floating points can lead to imprecise results) however I was having difficulties with comparing two double which were, indeed, equal, and yet using the 'compareTo' method didn't return 0.
I'm just leaving this there in case anyone needs to compare to check if they are indeed equal, and not just similar.
The EasyRGB has many color space conversions. Here is the code for the RGB->HSV conversion.
Another problem that happened me twice:
In IIS Express's applicationhost.config
the order of the bindings does matter. One binding could take precedence over your SSL binding, making it not working.
Example:
<site name="MySite007" id="1">
<application path="/" applicationPool="Clr4IntegratedAppPool">
<virtualDirectory path="/" physicalPath="C:\Users\myuser\projects\mysolutionfolder\MyProject.Service" />
</application>
<bindings>
<binding protocol="http" bindingInformation=":8081:localhost" />
<binding protocol="http" bindingInformation=":8080:" /><!-- evil binding -->
<binding protocol="https" bindingInformation="*:44327:localhost" />
</bindings>
</site>
You may have added a binding similar to the second one to be able to access your WebService from outside localhost
. Because this binding listens on any adress, it seems to override the SSL binding although a different port was used.
Remove the evil binding or move it down.
You can kill the process which is running the container.
With this command you can list the processes related with the docker container:
ps -aux | grep $(docker ps -a | grep container-name | awk '{print $1}')
Now you have the process ids to kill with kill or kill -9.
From a Spring point of view, none of the HttpMessageConverter
instances registered with the RestTemplate
can convert text/html
content to a ProductList
object. The method of interest is HttpMessageConverter#canRead(Class, MediaType)
. The implementation for all of the above returns false
, including Jaxb2RootElementHttpMessageConverter
.
Since no HttpMessageConverter
can read your HTTP response, processing fails with an exception.
If you can control the server response, modify it to set the Content-type
to application/xml
, text/xml
, or something matching application/*+xml
.
If you don't control the server response, you'll need to write and register your own HttpMessageConverter
(which can extend the Spring classes, see AbstractXmlHttpMessageConverter
and its sub classes) that can read and convert text/html
.

Yep: Use the outline
property; it acts as a second border outside of your border. Beware, tho', it can interact in a wonky fashion with margins, paddings and drop-shadows. In some browsers you might have to use a browser-specific prefix as well; in order to make sure it picks up on it: -webkit-outline
and the like (although WebKit in particular doesn't require this).
This can also be useful in the case where you want to jettison the outline for certain browsers (such as is the case if you want to combine the outline with a drop shadow; in WebKit the outline is inside of the shadow; in FireFox it is outside, so -moz-outline: 0
is useful to ensure that you don't get a gnarly line around your beautiful CSS drop shadow).
.someclass {
border: 1px solid blue;
outline: 1px solid darkblue;
}
Edit: Some people have remarked that outline
doesn't jive well with IE < 8. While this is true; supporting IE < 8 really isn't something you should be doing.

For me this problem occurred because I had a some invalid character in my Groovy script. In our case this was an extra blank line after the closing bracket of the script.
Assume you want to replace symbols which are not digits or letters (and _ character as @Guffa correctly pointed):
string input = "Hello@Hello&Hello(Hello)";
string result = Regex.Replace(input, @"[^\w\d]", ",");
// Hello,Hello,Hello,Hello,
You can add another symbols which should not be replaced. E.g. if you want white space symbols to stay, then just add \s
to pattern: \[^\w\d\s]
I second jdk's answer: any public static member of any class of your application can be considered as a "global variable".
However, do note that this is an ASP.NET application, and as such, it's a multi-threaded context for your global variables. Therefore, you should use some locking mechanism when you update and/or read the data to/from these variables. Otherwise, you might get your data in a corrupted state.
What you could do is something like this (pseudocode):
<container table>
<tr>
<td>
<"300px" table>
<td>
<fixed layout table>
Basically, split up the table into two tables and have it contained by another table.
To expand upon nosklo's explanation:
a = {}
b = ['some', 'list']
a[b] = 'some' # this won't work
a[tuple(b)] = 'some' # this will, same as a['some', 'list']
You can use -webkit-border-radius: 0;
. Like this:-
-webkit-border-radius: 0;
border: 0;
outline: 1px solid grey;
outline-offset: -1px;
This will give square corners as well as dropdown arrows. Using -webkit-appearance: none;
is not recommended as it will turn off all the styling done by Chrome.
here the problem is model binding if you specify a class then the model binding can understand it during the post if it an integer or string then you have to specify the [FromBody] to bind it properly.
make the following changes in FormMethod
using (@Html.BeginForm("myMethod", "Home", FormMethod.Post, new { id = @item.JobId })){
}
and inside your home controller for binding the string you should specify [FromBody]
using System.Web.Http;
[HttpPost]
public FileStreamResult myMethod([FromBody]string id)
{
// Set a local variable with the incoming data
string str = id;
}
FromBody is available in System.Web.Http. make sure you have the reference to that class and added it in the cs file.
That won't work if the string contains more than one match... try this:
echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo " $0) }'
or better (if the echo
isn't a placeholder for something else):
echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'
In your case you want to make a copy of the value before changing it:
echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'
Since the page you load inside the iframe can execute the "break out" code with a setInterval, onbeforeunload might not be that practical, since it could flud the user with 'Are you sure you want to leave?' dialogs.
There is also the iframe security attribute which only works on IE & Opera
:(

For Android device screen coordinates, below concept will work.
Display mdisp = getWindowManager().getDefaultDisplay();
Point mdispSize = new Point();
mdisp.getSize(mdispSize);
int maxX = mdispSize.x;
int maxY = mdispSize.y;
EDIT:- ** **for devices supporting android api level older than 13. Can use below code.
Display mdisp = getWindowManager().getDefaultDisplay();
int maxX= mdisp.getWidth();
int maxY= mdisp.getHeight();
(x,y) :-
1) (0,0) is top left corner.
2) (maxX,0) is top right corner
3) (0,maxY) is bottom left corner
4) (maxX,maxY) is bottom right corner
here maxX and maxY are screen maximum height and width in pixels, which we have retrieved in above given code.
has_key has been deprecated in Python 3.0. Alternatively you can use 'in'
graph={'A':['B','C'],
'B':['C','D']}
print('A' in graph)
>> True
print('E' in graph)
>> False
Suppose you run your program thus (using sh
syntax):
myprog arg1 arg2 'arg 3'
If you declared your main as int main(int argc, char *argv[])
, then (in most environments), your main()
will be called as if like:
p = { "myprog", "arg1", "arg2", "arg 3", NULL };
exit(main(4, p));
However, if you declared your main as int main()
, it will be called something like
exit(main());
and you don't get the arguments passed.
Two additional things to note:
main
. If a particular platform accepts extra arguments or a different return type, then that's an extension and should not be relied upon in a portable program.*argv[]
and **argv
are exactly equivalent, so you can write int main(int argc, char *argv[])
as int main(int argc, char **argv)
.Instead of taking the HttpServletRequest
object in every method, keep in controllers' context by auto-wiring via the constructor. Then you can access from all methods of the controller.
public class OAuth2ClientController {
@Autowired
private OAuth2ClientService oAuth2ClientService;
private HttpServletRequest request;
@Autowired
public OAuth2ClientController(HttpServletRequest request) {
this.request = request;
}
@RequestMapping(method = RequestMethod.POST)
public ResponseEntity<String> createClient(@RequestBody OAuth2Client client) {
System.out.println(request.getRequestURI());
System.out.println(request.getHeader("Content-Type"));
return ResponseEntity.ok();
}
}
Sorry this is wrong.
For changing background color/image based on the particular event(focus, press, normal), you need to define a button selector file and implement it as background for button.
For example: button_selector.xml (define this file inside the drawable folder)
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:color="#000000" /> <!-- pressed -->
<item android:state_focused="true"
android:color="#000000" /> <!-- focused -->
<item android:color="#FFFFFF" /> <!-- default -->
</selector>
<!-- IF you want image instead of color then write
android:drawable="@drawable/your_image" inside the <item> tag -->
And apply it as:
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawable="@drawable/button_selector.xml" />
use:
var parsedobj = jQuery.parseJSON( jsonObj);
This will only be useful if you don't need the format to stay in string. otherwise you'd have to convert this back to JSON using the JSON library.
I solved this issue by extending the Preference class.
package com.example.android;
import android.content.Context;
import android.preference.Preference;
import android.util.AttributeSet;
public class VersionPreference extends Preference {
public VersionPreference(Context context, AttributeSet attrs) {
super(context, attrs);
String versionName;
final PackageManager packageManager = context.getPackageManager();
if (packageManager != null) {
try {
PackageInfo packageInfo = packageManager.getPackageInfo(context.getPackageName(), 0);
versionName = packageInfo.versionName;
} catch (PackageManager.NameNotFoundException e) {
versionName = null;
}
setSummary(versionName);
}
}
}
Then in my preferences XML:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<com.example.android.VersionPreference android:title="Version" />
</PreferenceScreen>
have you tried eager loading?
@attachments = Job.includes(:attachments).find(1).attachments
If you want to paste some clipboard content at the end of the file type:
:$ put +
$ ............ last line
put .......... paste
+ ............ clipboard
function sample() {
alert("This is sample function");
}
$(function() {
$("#button").click(function() {
setTimeout(sample, 2000);
});
});
If you want to encapsulate sample()
there, wrap the whole thing in a self invoking function (function() { ... })()
.
To solve this problem, also check if you have some included .js into your ajax file called: I received Access denied error while including shadowbox.js in my ajax.php
The definition of asarray
is:
def asarray(a, dtype=None, order=None):
return array(a, dtype, copy=False, order=order)
So it is like array
, except it has fewer options, and copy=False
. array
has copy=True
by default.
The main difference is that array
(by default) will make a copy of the object, while asarray
will not unless necessary.
If i run the command line : java -Dspring.profiles.active=development -jar yourApplication.jar
from my webapplication directory it states that the path is incorrect. So i just defined the profile in manualy in the application.properties file like this :
spring.profiles.active=mysql
or
spring.profiles.active=postgres
or
spring.profiles.active=mongodb
You can also use array_keys()
. Newbie friendly:
$keys = array_keys($arrayToWalk);
$arraySize = count($arrayToWalk);
for($i=0; $i < $arraySize; $i++) {
echo '<option value="' . $keys[$i] . '">' . $arrayToWalk[$keys[$i]] . '</option>';
}
Please try either of these commands first;
$ py -m notebook
$ python -m notebook
for jupyterlab users
py -m jupyterlab
Otherwise
$ python -m pip install jupyter --user
$ jupyter notebook
If this does not work.
pip does not add jupyter directly to path for local.
The output from
$ which python
/c/Users/<username>/AppData/Local/Programs/Python/Python35-32/python
After some digging I found a executable for jupyter in the folder:
C:\Users\<username>\AppData\Roaming\Python\Python35\Scripts\jupyter.exe
Difference between local and roaming folder
So if you want to be able to execute a program via command line, you need to add it into the %PATH variable. Here is a powershell script to do it. BE SURE TO ADD THE ";" before adding the new path.
$ [Environment]::SetEnvironmentVariable("Path", $env:Path + ";C:\Users\<username>\AppData\Roaming\Python\Python35\Scripts", [EnvironmentVariableTarget]::User)
Update:
if you are using python3
, switch out python
with python3
but I encourage you to use pyenv
instead :)
Make sure you’re pushing the right branch. I wasn’t on master
and kept wondering why it was complaining :P
For inserting elements into an array with string keys you can do something like this:
/* insert an element after given array key
* $src = array() array to work with
* $ins = array() to insert in key=>array format
* $pos = key that $ins will be inserted after
*/
function array_insert_string_keys($src,$ins,$pos) {
$counter=1;
foreach($src as $key=>$s){
if($key==$pos){
break;
}
$counter++;
}
$array_head = array_slice($src,0,$counter);
$array_tail = array_slice($src,$counter);
$src = array_merge($array_head, $ins);
$src = array_merge($src, $array_tail);
return($src);
}
If you have linked the node packages using sudo command
Then go to the folder where node_modules are installed globally.
On Unix systems they are normally placed in /usr/local/lib/node or /usr/local/lib/node_modules when installed globally. If you set the NODE_PATH environment variable to this path, the modules can be found by node.
Windows XP - %USERPROFILE%\Application Data\npm\node_modules Windows 7 - %AppData%\npm\node_modules
and then run the command
ls -l
This will give the list of all global node_modules and you can easily see the linked node modules.
Compact solution (provided you don't need other environment variables):
call('sqsub -np {} /homedir/anotherdir/executable'.format(var1).split(),
env=dict(LD_LIBRARY_PATH=my_path))
Using the env command line tool:
call('env LD_LIBRARY_PATH=my_path sqsub -np {} /homedir/anotherdir/executable'.format(var1).split())
Git has the concept of "remotes", which are simply URLs to other copies of your repository. When you clone another repository, Git automatically creates a remote named "origin" and points to it.
You can see more information about the remote by typing git remote show origin
.
You can use the Enumerable.SequenceEqual() in the System.Linq to compare the contents in the array
bool isEqual = Enumerable.SequenceEqual(target1, target2);
The standard equivalent of find -iname ... -exec mv -t dest {} +
for find
implementations that don't support -iname
or mv
implementations that don't support -t
is to use a shell to re-order the arguments:
find . -name '*.[cC][pP][pP]' -type f -exec sh -c '
exec mv "$@" /dest/dir/' sh {} +
By using -name '*.[cC][pP][pP]'
, we also avoid the reliance on the current locale to decide what's the uppercase version of c
or p
.
Note that +
, contrary to ;
is not special in any shell so doesn't need to be quoted (though quoting won't harm, except of course with shells like rc
that don't support \
as a quoting operator).
The trailing /
in /dest/dir/
is so that mv
fails with an error instead of renaming foo.cpp
to /dest/dir
in the case where only one cpp
file was found and /dest/dir
didn't exist or wasn't a directory (or symlink to directory).
As the lines can be variable in logs I thought it best to take a number of lines per file approach. The following code snippet processed a 4 million line log file in under 19 seconds (18.83.. seconds)splitting it into 500,000 line chunks:
$sourceFile = "c:\myfolder\mylargeTextyFile.csv"
$partNumber = 1
$batchSize = 500000
$pathAndFilename = "c:\myfolder\mylargeTextyFile part $partNumber file.csv"
[System.Text.Encoding]$enc = [System.Text.Encoding]::GetEncoding(65001) # utf8 this one
$fs=New-Object System.IO.FileStream ($sourceFile,"OpenOrCreate", "Read", "ReadWrite",8,"None")
$streamIn=New-Object System.IO.StreamReader($fs, $enc)
$streamout = new-object System.IO.StreamWriter $pathAndFilename
$line = $streamIn.readline()
$counter = 0
while ($line -ne $null)
{
$streamout.writeline($line)
$counter +=1
if ($counter -eq $batchsize)
{
$partNumber+=1
$counter =0
$streamOut.close()
$pathAndFilename = "c:\myfolder\mylargeTextyFile part $partNumber file.csv"
$streamout = new-object System.IO.StreamWriter $pathAndFilename
}
$line = $streamIn.readline()
}
$streamin.close()
$streamout.close()
This can easily be turned into a function or script file with parameters to make it more versatile. It uses a StreamReader
and StreamWriter
to achieve its speed and tiny memory footprint
In reguards to using jQuery to do hover, I always use the plugin HoverIntent as it doesn't fire the event until you pause over an element for brief period of time... this stops firing off lots of mouse over events if you accidentally run the mouse over them or simply whilst choosing an option.
Generally speaking, this is the configuration file of web applications in java. It instructs the servlet container (tomcat for ex.) which classes to load, what parameters to set in the context, and how to intercept requests coming from browsers.
There you specify:
In servlet 3.0 many of the web.xml parts are optional. These configurations can be done via annotations (@WebServlet
, @WebListener
)
You should use the * operator, like foo(*values)
Read the Python doc unpackaging argument lists.
Also, do read this: http://www.saltycrane.com/blog/2008/01/how-to-use-args-and-kwargs-in-python/
def foo(x,y,z):
return "%d, %d, %d" % (x,y,z)
values = [1,2,3]
# the solution.
foo(*values)
To your remark in the comments to your question:
"...SavingChanges (for each record)..."
That's the worst thing you can do! Calling SaveChanges()
for each record slows bulk inserts extremely down. I would do a few simple tests which will very likely improve the performance:
SaveChanges()
once after ALL records.SaveChanges()
after for example 100 records.SaveChanges()
after for example 100 records and dispose the context and create a new one.For bulk inserts I am working and experimenting with a pattern like this:
using (TransactionScope scope = new TransactionScope())
{
MyDbContext context = null;
try
{
context = new MyDbContext();
context.Configuration.AutoDetectChangesEnabled = false;
int count = 0;
foreach (var entityToInsert in someCollectionOfEntitiesToInsert)
{
++count;
context = AddToContext(context, entityToInsert, count, 100, true);
}
context.SaveChanges();
}
finally
{
if (context != null)
context.Dispose();
}
scope.Complete();
}
private MyDbContext AddToContext(MyDbContext context,
Entity entity, int count, int commitCount, bool recreateContext)
{
context.Set<Entity>().Add(entity);
if (count % commitCount == 0)
{
context.SaveChanges();
if (recreateContext)
{
context.Dispose();
context = new MyDbContext();
context.Configuration.AutoDetectChangesEnabled = false;
}
}
return context;
}
I have a test program which inserts 560.000 entities (9 scalar properties, no navigation properties) into the DB. With this code it works in less than 3 minutes.
For the performance it is important to call SaveChanges()
after "many" records ("many" around 100 or 1000). It also improves the performance to dispose the context after SaveChanges and create a new one. This clears the context from all entites, SaveChanges
doesn't do that, the entities are still attached to the context in state Unchanged
. It is the growing size of attached entities in the context what slows down the insertion step by step. So, it is helpful to clear it after some time.
Here are a few measurements for my 560000 entities:
The behaviour in the first test above is that the performance is very non-linear and decreases extremely over time. ("Many hours" is an estimation, I never finished this test, I stopped at 50.000 entities after 20 minutes.) This non-linear behaviour is not so significant in all other tests.
The method is implicitly defined (i.e. generated by the compiler).
From the JLS:
In addition, if
E
is the name of anenum
type, then that type has the following implicitly declaredstatic
methods:/** * Returns an array containing the constants of this enum * type, in the order they're declared. This method may be * used to iterate over the constants as follows: * * for(E c : E.values()) * System.out.println(c); * * @return an array containing the constants of this enum * type, in the order they're declared */ public static E[] values(); /** * Returns the enum constant of this type with the specified * name. * The string must match exactly an identifier used to declare * an enum constant in this type. (Extraneous whitespace * characters are not permitted.) * * @return the enum constant with the specified name * @throws IllegalArgumentException if this enum type has no * constant with the specified name */ public static E valueOf(String name);
After the blog post How Can I Use Windows PowerShell to Delete All the .TMP Files on a Drive?, you can use something like this to delete all .tmp for example from a folder and all subfolders in PowerShell:
get-childitem [your path/ or leave empty for current path] -include
*.tmp -recurse | foreach ($_) {remove-item $_.fullname}
Download commons-net binary from here. Extract the files and reference the commons-net-x.x.jar file.
$files = glob($_SERVER["DOCUMENT_ROOT"]."/myFolder/*");
This was my solution to protect against an empty array as well:
import React, { Component } from 'react';
import { arrayOf, shape, string, number } from 'prop-types';
ReactComponent.propTypes = {
arrayWithShape: (props, propName, componentName) => {
const arrayWithShape = props[propName]
PropTypes.checkPropTypes({ arrayWithShape:
arrayOf(
shape({
color: string.isRequired,
fontSize: number.isRequired,
}).isRequired
).isRequired
}, {arrayWithShape}, 'prop', componentName);
if(arrayWithShape.length < 1){
return new Error(`${propName} is empty`)
}
}
}
Have you looked at the Aggregate extension method?
var sa = (new[] { "yabba", "dabba", "doo" }).Aggregate((a,b) => a + "," + b);
Change the 5
to 5.0
. You're getting integer division.
The CSS below stops users from being able to select text.
-webkit-user-select: none; /* Safari */
-moz-user-select: none; /* Firefox */
-ms-user-select: none; /* IE10+/Edge */
user-select: none; /* Standard */
To target IE9 downwards the html attribute unselectable
must be used instead:
<p unselectable="on">Test Text</p>
You could use IIF
statement like in the next example:
SELECT
IIF(test_expression, value_if_true, value_if_false) AS FIELD_NAME
FROM
TABLE_NAME
Your mileage may vary (mine sure did), but here's what worked for me (current version of Chrome as of this post is 33.x, and I was interested in 24.x)
Visit the Chromium repo proxy lookup site: http://omahaproxy.appspot.com/
In the little box called "Revision Lookup" type in the version number. This will translate it to a Subversion revision number. Keep that number in mind.
Visit the build repository: http://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html
Select the folder corresponding to the OS you're interested in (I have Win x64, but had to use Win,because there was no x64 build corresponding to the version I was looking for).
If you select Win, you could be in for a wait - as some of the pages have a lot of entries. Once the page loads, scroll to the folder containing the revision number you identified in an earlier step. If you don't find one, choose the next one up. This is a bit of trial and error to be honest - I had to back up about 50 revisions until I found a version close to the one I was looking for
Drill into that folder and download (on the Win version) chrome-win32.zip. That's all you need.
Unzip that file and then run chrome.exe
This worked for me and I'm running the latest Chrome alongside version 25, without problems (some profile issues on the older version, but that's neither here nor there). Didn't need to do anything else.
Again, YMMV, but try this solution first since it requires the least amount of tomfoolery.
my problem was to copy the whole source files contains .idea directory and my webstorm terminal commands were run on the original directory of the source
I delete the .idea directory and it worked fine
Like Jaanus told:
Calling this (-selectRowAtIndexPath:animated:scrollPosition:) method does not cause the delegate to receive a tableView:willSelectRowAtIndexPath: or tableView:didSelectRowAtIndexPath: message, nor will it send UITableViewSelectionDidChangeNotification notifications to observers.
So you just have to call the delegate
method yourself.
For example:
Swift 3 version:
let indexPath = IndexPath(row: 0, section: 0);
self.tableView.selectRow(at: indexPath, animated: false, scrollPosition: UITableViewScrollPosition.none)
self.tableView(self.tableView, didSelectRowAt: indexPath)
ObjectiveC version:
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[self.tableView selectRowAtIndexPath:indexPath
animated:YES
scrollPosition:UITableViewScrollPositionNone];
[self tableView:self.tableView didSelectRowAtIndexPath:indexPath];
Swift 2.3 version:
let indexPath = NSIndexPath(forRow: 0, inSection: 0);
self.tableView.selectRowAtIndexPath(indexPath, animated: false, scrollPosition: UITableViewScrollPosition.None)
self.tableView(self.tableView, didSelectRowAtIndexPath: indexPath)
As others have said, it's a direct child, but it's worth noting that this is different to just leaving a space... a space is for any descendant.
<div>
<span>Some text</span>
</div>
div>span
would match this, but it would not match this:
<div>
<p><span>Some text</span></p>
</div>
To match that, you could do div>p>span
or div span
.
