There are some problems with the Erlang implementation. As baseline for the following, my measured execution time for your unmodified Erlang program was 47.6 seconds, compared to 12.7 seconds for the C code.
The first thing you should do if you want to run computationally intensive Erlang code is to use native code. Compiling with erlc +native euler12
got the time down to 41.3 seconds. This is however a much lower speedup (just 15%) than expected from native compilation on this kind of code, and the problem is your use of -compile(export_all)
. This is useful for experimentation, but the fact that all functions are potentially reachable from the outside causes the native compiler to be very conservative. (The normal BEAM emulator is not that much affected.) Replacing this declaration with -export([solve/0]).
gives a much better speedup: 31.5 seconds (almost 35% from the baseline).
But the code itself has a problem: for each iteration in the factorCount loop, you perform this test:
factorCount (_, Sqrt, Candidate, Count) when Candidate == Sqrt -> Count + 1;
The C code doesn't do this. In general, it can be tricky to make a fair comparison between different implementations of the same code, and in particular if the algorithm is numerical, because you need to be sure that they are actually doing the same thing. A slight rounding error in one implementation due to some typecast somewhere may cause it to do many more iterations than the other even though both eventually reach the same result.
To eliminate this possible error source (and get rid of the extra test in each iteration), I rewrote the factorCount function as follows, closely modelled on the C code:
factorCount (N) ->
Sqrt = math:sqrt (N),
ISqrt = trunc(Sqrt),
if ISqrt == Sqrt -> factorCount (N, ISqrt, 1, -1);
true -> factorCount (N, ISqrt, 1, 0)
end.
factorCount (_N, ISqrt, Candidate, Count) when Candidate > ISqrt -> Count;
factorCount ( N, ISqrt, Candidate, Count) ->
case N rem Candidate of
0 -> factorCount (N, ISqrt, Candidate + 1, Count + 2);
_ -> factorCount (N, ISqrt, Candidate + 1, Count)
end.
This rewrite, no export_all
, and native compilation, gave me the following run time:
$ erlc +native euler12.erl
$ time erl -noshell -s euler12 solve
842161320
real 0m19.468s
user 0m19.450s
sys 0m0.010s
which is not too bad compared to the C code:
$ time ./a.out
842161320
real 0m12.755s
user 0m12.730s
sys 0m0.020s
considering that Erlang is not at all geared towards writing numerical code, being only 50% slower than C on a program like this is pretty good.
Finally, regarding your questions:
Question 1: Do erlang, python and haskell loose speed due to using arbitrary length integers or don't they as long as the values are less than MAXINT?
Yes, somewhat. In Erlang, there is no way of saying "use 32/64-bit arithmetic with wrap-around", so unless the compiler can prove some bounds on your integers (and it usually can't), it must check all computations to see if they can fit in a single tagged word or if it has to turn them into heap-allocated bignums. Even if no bignums are ever used in practice at runtime, these checks will have to be performed. On the other hand, that means you know that the algorithm will never fail because of an unexpected integer wraparound if you suddenly give it larger inputs than before.
Question 4: Do my functional implementations permit LCO and hence avoid adding unnecessary frames onto the call stack?
Yes, your Erlang code is correct with respect to last call optimization.
Just put one more entry in your spring xml file i.e.mvc-dispatcher-servlet.xml
<mvc:view-controller path="/" view-name="index"/>
After putting this to your xml put your default view or jsp file in your custom JSP folder as you have mentioned in mvc-dispatcher-servlet.xml
file.
change index
with your jsp name.
If elements are always nearly sorted as in your example then builtin .sort()
(timsort) should be fast:
>>> a = [1,1,2]
>>> b = [1,2,2]
>>> a.sort()
>>> b.sort()
>>> a == b
False
If you don't want to sort inplace you could use sorted()
.
In practice it might always be faster then collections.Counter()
(despite asymptotically O(n)
time being better then O(n*log(n))
for .sort()
). Measure it; If it is important.
I know this is a little late, but here's the solution I had to come up with for handling dates when you want to be timezone independent. Essentially it involves converting everything to UTC.
From Javascript to Server:
Send out dates as epoch values with the timezone offset removed.
var d = new Date(2015,0,1) // Jan 1, 2015
// Ajax Request to server ...
$.ajax({
url: '/target',
params: { date: d.getTime() - (d.getTimezoneOffset() * 60 * 1000) }
});
The server then recieves 1420070400000 as the date epoch.
On the Server side, convert that epoch value to a datetime object:
DateTime d = new DateTime(1970, 1, 1, 0, 0, 0).AddMilliseconds(epoch);
At this point the date is just the date/time provided by the user as they provided it. Effectively it is UTC.
Going the other way:
When the server pulls data from the database, presumably in UTC, get the difference as an epoch (making sure that both date objects are either local or UTC):
long ms = (long)utcDate.Subtract(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalMilliseconds;
or
long ms = (long)localDate.Subtract(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Local)).TotalMilliseconds;
When javascript receives this value, create a new date object. However, this date object is going to be assumed local time, so you need to offset it by the current timezone:
var epochValue = 1420070400000 // value pulled from server.
var utcDateVal = new Date(epochValue);
var actualDate = new Date(utcDateVal.getTime() + (utcDateVal.getTimezoneOffset() * 60 * 1000))
console.log(utcDateVal); // Wed Dec 31 2014 19:00:00 GMT-0500 (Eastern Standard Time)
console.log(actualDate); // Thu Jan 01 2015 00:00:00 GMT-0500 (Eastern Standard Time)
As far as I know, this should work for any time zone where you need to display dates that are timezone independent.
The scope resolution operator is also called "Paamayim Nekudotayim" from the Hebrew ?????? ?????????. which means "double colon".
This error typically happens if you inadvertently put ::
in your code.

Consider this algorithm. When your script loads (if there are multiple identical scripts), look through document.scripts, find the first script with the correct "src" attribute, and save it and mark it as 'visited' with a data-attribute or unique className.
When the next script loads, scan through document.scripts again, passing over any script already marked as visited. Take the first unvisited instance of that script.
This assumes that identical scripts will likely execute in the order in which they are loaded, from head to body, from top to bottom, from synchronous to asynchronous.
(function () {
var scripts = document.scripts;
// Scan for this data-* attribute
var dataAttr = 'data-your-attribute-here';
var i = 0;
var script;
while (i < scripts.length) {
script = scripts[i];
if (/your_script_here\.js/i.test(script.src)
&& !script.hasAttribute(dataAttr)) {
// A good match will break the loop before
// script is set to null.
break;
}
// If we exit the loop through a while condition failure,
// a check for null will reveal there are no matches.
script = null;
++i;
}
/**
* This specific your_script_here.js script tag.
* @type {Element|Node}
*/
var yourScriptVariable = null;
// Mark the script an pass it on.
if (script) {
script.setAttribute(dataAttr, '');
yourScriptVariable = script;
}
})();
This will scan through all the script for the first matching script that isn't marked with the special attribute.
Then mark that node, if found, with a data-attribute so subsequent scans won't choose it. This is similar to graph traversal BFS and DFS algorithms where nodes may be marked as 'visited' to prevent revisitng.
The answer to my own question is, I think, to use tomcat7.exe:
cd $CATALINA_HOME
.\bin\service.bat install tomcat
.\bin\tomcat7.exe //US//tomcat7 --JvmMs=512 --JvmMx=1024 --JvmSs=1024
Also, you can launch the UI tool mentioned by BalusC without the system tray or using the installer with tomcat7w.exe
.\bin\tomcat7w.exe //ES//tomcat
An additional note to this:
Setting the --JvmXX parameters (through the UI tool or the command line) may not be enough. You may also need to specify the JVM memory values explicitly. From the command line it may look like this:
bin\tomcat7w.exe //US//tomcat7 --JavaOptions=-Xmx=1024;-Xms=512;..
Be careful not to override the other JavaOption values. You can try updating bin\service.bat or use the UI tool and append the java options (separate each value with a new line).
No! There is no 64-bit version of Visual Studio.
How to know it is not 64-bit: Once you download Visual Studio and click the install button, you will see that the initialization folder it selects automatically is C:\Program Files (x86)\Microsoft Visual Studio 14.0
As per my understanding, all 64-bit programs/applications goes to C:\Program Files and all 32-bit applications goes to C:\Program Files (x86) from Windows 7 onwards.

I would recommend using <br />
for the following reasons:
1) Text and XML editors that highlight XML syntax in different colours will highlight properly with <br />
but this is not always the case if you use <br>
2) <br />
is backwards-compatible with XHTML and well-formed HTML (ie: XHTML) is often easier to validate for errors and debug
3) Some old parsers and some coding specs require the space before the closing slash (ie: <br />
instead of <br/>
) such as the WordPress Plugin Coding spec: http://make.wordpress.org/core/handbook/coding-standards/html/
I my experience, I have never come across a case where using <br />
is problematic, however, there are many cases where <br/>
or especially <br>
might be problematic in older browsers and tools.
I stopped writing this myself for laravel in favor of the Laracasts package that handles it all for you. It is really easy to use and keeps your code clean. There is even a laracast that covers how to use it. All you have to do:
Pull in the package through Composer.
"require": {
"laracasts/flash": "~1.0"
}
Include the service provider within app/config/app.php.
'providers' => [
'Laracasts\Flash\FlashServiceProvider'
];
Add a facade alias to this same file at the bottom:
'aliases' => [
'Flash' => 'Laracasts\Flash\Flash'
];
Pull the HTML into the view:
@include('flash::message')
There is a close button on the right of the message. This relies on jQuery so make sure that is added before your bootstrap.
optional changes:
If you aren't using bootstrap or want to skip the include of the flash message and write the code yourself:
@if (Session::has('flash_notification.message'))
<div class="{{ Session::get('flash_notification.level') }}">
{{ Session::get('flash_notification.message') }}
</div>
@endif
If you would like to view the HTML pulled in by @include('flash::message')
, you can find it in vendor/laracasts/flash/src/views/message.blade.php
.
If you need to modify the partials do:
php artisan view:publish laracasts/flash
The two package views will now be located in the `app/views/packages/laracasts/flash/' directory.
If you want some space at left
and right
of input
view, you can add some padding like
private fun showAlertWithTextInputLayout(context: Context) {
val textInputLayout = TextInputLayout(context)
textInputLayout.setPadding(
resources.getDimensionPixelOffset(R.dimen.dp_19), // if you look at android alert_dialog.xml, you will see the message textview have margin 14dp and padding 5dp. This is the reason why I use 19 here
0,
resources.getDimensionPixelOffset(R.dimen.dp_19),
0
)
val input = EditText(context)
textInputLayout.hint = "Email"
textInputLayout.addView(input)
val alert = AlertDialog.Builder(context)
.setTitle("Reset Password")
.setView(textInputLayout)
.setMessage("Please enter your email address")
.setPositiveButton("Submit") { dialog, _ ->
// do some thing with input.text
dialog.cancel()
}
.setNegativeButton("Cancel") { dialog, _ ->
dialog.cancel()
}.create()
alert.show()
}
dimens.xml
<dimen name="dp_19">19dp</dimen>
Hope it help
How are you loading the values into the drop down list or determining which value to select? If you are doing this using Ajax, then the reason you need the delay before the selection occurs could be because the values were not loaded in at the time that the line in question executed. This would also explain why it worked when you put an alert statement on the line before setting the status since the alert action would give enough of a delay for the data to load.
If you are using one of jQuery's Ajax methods, you can specify a callback function and then put $("._statusDDL").val(2);
into your callback function.
This would be a more reliable way of handling the issue since you could be sure that the method executed when the data was ready, even if it took longer than 300 ms.
Although I almost always just use pandas for this, my current little tool is being packaged into an executable and including pandas is overkill. So I created a version of poida's solution that resulted in a list of named tuples. His code with this change would look like this:
from xlrd import open_workbook
from collections import namedtuple
from pprint import pprint
wb = open_workbook('sample.xls')
FORMAT = ['Arm_id', 'DSPName', 'PinCode']
OneRow = namedtuple('OneRow', ' '.join(FORMAT))
all_rows = []
for s in wb.sheets():
headerRow = s.row(0)
columnIndex = [x for y in FORMAT for x in range(len(headerRow)) if y == headerRow[x].value]
for row in range(1,s.nrows):
currentRow = s.row(row)
currentRowValues = [currentRow[x].value for x in columnIndex]
all_rows.append(OneRow(*currentRowValues))
pprint(all_rows)
PuTTY can't find where your X server is, because you didn't tell it. (ssh on Linux doesn't have this problem because it runs under X so it just uses that one.) Fill in the blank box after "X display location" with your Xming server's address.
Alternatively, try MobaXterm. It has an X server builtin.
I fixed my pythonpath and everything was dandy when I imported stuff through the console, but all these previously unresolved imports were still marked as errors in my code, no matter how many times I restarted eclipse or refreshed/cleaned the project.
I right clicked the project->Pydev->Remove error markers and it got rid of that problem. Don't worry, if your code contains actual errors they will be re-marked.
You can use x.astype('uint8')
where x
is your Boolean array.

i've got the following function in my "standard library"
/// Convert argument to an array.
function a($a = null) {

return $a;
if(is_object($a))
return (array) $a;
return $_ = func_get_args();
}
Basically, this does nothing with arrays/objects and convert other types to arrays. This is extremely handy to use with foreach statements and array functions
foreach(a($whatever) as $item)....
$foo = array_map(a($array_or_string)....
etc
I've just faced the same issue and I came to believe that the other answers are a bit more complicated than they need to be, so here's my approach for those who don't want to rely on more libraries or decorators:
A CORS request actually consists of two HTTP requests. A preflight request and then an actual request that is only made if the preflight passes successfully.
Before the actual cross domain POST
request, the browser will issue an OPTIONS
request. This response should not return any body, but only some reassuring headers telling the browser that it's alright to do this cross-domain request and it's not part of some cross site scripting attack.
I wrote a Python function to build this response using the make_response
function from the flask
module.
def _build_cors_prelight_response():
response = make_response()
response.headers.add("Access-Control-Allow-Origin", "*")
response.headers.add("Access-Control-Allow-Headers", "*")
response.headers.add("Access-Control-Allow-Methods", "*")
return response
This response is a wildcard one that works for all requests. If you want the additional security gained by CORS, you have to provide a whitelist of origins, headers and methods.
This response will convince your (Chrome) browser to go ahead and do the actual request.
When serving the actual request you have to add one CORS header - otherwise the browser won't return the response to the invoking JavaScript code. Instead the request will fail on the client-side. Example with jsonify
response = jsonify({"order_id": 123, "status": "shipped"}
response.headers.add("Access-Control-Allow-Origin", "*")
return response
I also wrote a function for that.
def _corsify_actual_response(response):
response.headers.add("Access-Control-Allow-Origin", "*")
return response
allowing you to return a one-liner.
from flask import Flask, request, jsonify, make_response
from models import OrderModel
flask_app = Flask(__name__)
@flask_app.route("/api/orders", methods=["POST", "OPTIONS"])
def api_create_order():
if request.method == "OPTIONS": # CORS preflight
return _build_cors_prelight_response()
elif request.method == "POST": # The actual request following the preflight
order = OrderModel.create(...) # Whatever.
return _corsify_actual_response(jsonify(order.to_dict()))
else
raise RuntimeError("Weird - don't know how to handle method {}".format(request.method))
def _build_cors_prelight_response():
response = make_response()
response.headers.add("Access-Control-Allow-Origin", "*")
response.headers.add('Access-Control-Allow-Headers', "*")
response.headers.add('Access-Control-Allow-Methods', "*")
return response
def _corsify_actual_response(response):
response.headers.add("Access-Control-Allow-Origin", "*")
return response
Try this:
$('#select_all').click(function() {
$('#countries option').prop('selected', true);
});
And here's a live demo.
your http service file:
import { Injectable } from "@angular/core";
import { ActivatedRoute, Router } from '@angular/router';
import { Http, Headers, Response, Request, RequestMethod, URLSearchParams, RequestOptions } from "@angular/http";
import {Observable} from 'rxjs/Rx';
import { Constants } from './constants';
declare var $: any;
@Injectable()
export class HttpClient {
requestUrl: string;
responseData: any;
handleError: any;
constructor(private router: Router,
private http: Http,
private constants: Constants,
) {
this.http = http;
}
postWithFile (url: string, postData: any, files: File[]) {
let headers = new Headers();
let formData:FormData = new FormData();
formData.append('files', files[0], files[0].name);
// For multiple files
// for (let i = 0; i < files.length; i++) {
// formData.append(`files[]`, files[i], files[i].name);
// }
if(postData !=="" && postData !== undefined && postData !==null){
for (var property in postData) {
if (postData.hasOwnProperty(property)) {
formData.append(property, postData[property]);
}
}
}
var returnReponse = new Promise((resolve, reject) => {
this.http.post(this.constants.root_dir + url, formData, {
headers: headers
}).subscribe(
res => {
this.responseData = res.json();
resolve(this.responseData);
},
error => {
this.router.navigate(['/login']);
reject(error);
}
);
});
return returnReponse;
}
}
call your function (Component file):
onChange(event) {
let file = event.srcElement.files;
let postData = {field1:"field1", field2:"field2"}; // Put your form data variable. This is only example.
this._service.postWithFile(this.baseUrl + "add-update",postData,file).then(result => {
console.log(result);
});
}
your html code:
<input type="file" class="form-control" name="documents" (change)="onChange($event)" [(ngModel)]="stock.documents" #documents="ngModel">
It's not doable with CSS2.1, but it is possible with CSS3 attribute substring-matching selectors (which are supported in IE7+):
div[class^="status-"], div[class*=" status-"]
Notice the space character in the second attribute selector. This picks up div
elements whose class
attribute meets either of these conditions:
[class^="status-"]
— starts with "status-"
[class*=" status-"]
— contains the substring "status-" occurring directly after a space character. Class names are separated by whitespace per the HTML spec, hence the significant space character. This checks any other classes after the first if multiple classes are specified, and adds a bonus of checking the first class in case the attribute value is space-padded (which can happen with some applications that output class
attributes dynamically).
Naturally, this also works in jQuery, as demonstrated here.
The reason you need to combine two attribute selectors as described above is because an attribute selector such as [class*="status-"]
will match the following element, which may be undesirable:
<div id='D' class='foo-class foo-status-bar bar-class'></div>
If you can ensure that such a scenario will never happen, then you are free to use such a selector for the sake of simplicity. However, the combination above is much more robust.
If you have control over the HTML source or the application generating the markup, it may be simpler to just make the status-
prefix its own status
class instead as Gumbo suggests.
HTML:
<video
id="video-active"
class="video-active"
width="640"
height="390"
controls="controls">
<source src="myvideo.mp4" type="video/mp4">
</video>
<div id="current">0:00</div>
<div id="duration">0:00</div>
JavaScript:
$(document).ready(function(){
$("#video-active").on(
"timeupdate",
function(event){
onTrackedVideoFrame(this.currentTime, this.duration);
});
});
function onTrackedVideoFrame(currentTime, duration){
$("#current").text(currentTime); //Change #current to currentTime
$("#duration").text(duration)
}
Notes:
Every 15 to 250ms, or whenever the MediaController's media controller position changes, whichever happens least often, the user agent must queue a task to fire a simple event named timeupdate at the MediaController.

Supposing you have the following file structure:
-css
--index.css
-images
--image1.png
--image2.png
--image3.png
In CSS you can access image1
, for example, using the line ../images/image1.png
.
NOTE: If you are using Chrome, it may doesn't work and you will get an error that the file could not be found. I had the same problem, so I just deleted the entire cache history from chrome and it worked.
Just disable the VIA protocol in sql server configuration manager
This is exceedingly tricky in standard Unix, and most solutions run foul of newlines or some other character. However, if you are using the GNU tool set, then you can exploit the find
option -print0
and use xargs
with the corresponding option -0
(minus-zero). There are two characters that cannot appear in a simple filename; those are slash and NUL '\0'. Obviously, slash appears in pathnames, so the GNU solution of using a NUL '\0' to mark the end of the name is ingenious and fool-proof.
It failed because you used ajax="false"
. This fires a full synchronous request which in turn causes a full page reload, causing the oncomplete
to be never fired (note that all other ajax-related attributes like process
, onstart
, onsuccess
, onerror
and update
are also never fired).
That it worked when you removed actionListener
is also impossible. It should have failed the same way. Perhaps you also removed ajax="false"
along it without actually understanding what you were doing. Removing ajax="false"
should indeed achieve the desired requirement.
Also is it possible to execute actionlistener and oncomplete simultaneously?
No. The script can only be fired before or after the action listener. You can use onclick
to fire the script at the moment of the click. You can use onstart
to fire the script at the moment the ajax request is about to be sent. But they will never exactly simultaneously be fired. The sequence is as follows:
onclick
JavaScript code is executedprocess
and current HTML DOM treeonstart
JavaScript code is executedprocess
actionListener
JSF backing bean method is executedaction
JSF backing bean method is executedupdate
and current JSF component treeonsuccess
JavaScript code is executedonerror
JavaScript code is executedupdate
based on ajax response and current HTML DOM treeoncomplete
JavaScript code is executedNote that the update
is performed after actionListener
, so if you were using onclick
or onstart
to show the dialog, then it may still show old content instead of updated content, which is poor for user experience. You'd then better use oncomplete
instead to show the dialog. Also note that you'd better use action
instead of actionListener
when you intend to execute a business action.
closest()
selects the first element that matches the selector, up from the DOM tree. Begins from the current element and travels up.
parent()
selects one element up (single level up) the DOM tree.
parents()
method is similar toparent()
but selects all the matching elements up the DOM tree. Begins from the parent element and travels up.
This is specifically mentioned in the libcurl FAQ entry "Protocol xxx not supported or disabled in libcurl".
For your pleasure I'm embedding the explanation here too:
When passing on a URL to curl to use, it may respond that the particular protocol is not supported or disabled. The particular way this error message is phrased is because curl doesn't make a distinction internally of whether a particular protocol is not supported (ie never got any code added that knows how to speak that protocol) or if it was explicitly disabled. curl can be built to only support a given set of protocols, and the rest would then be disabled or not supported.
Note that this error will also occur if you pass a wrongly spelled protocol part as in "htpt://example.com" or as in the less evident case if you prefix the protocol part with a space as in " http://example.com/".
You see the two empty -D
entries in the g++
command line? They're causing the problem. You must have values in the -D
items e.g. -DWIN32
if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:
SYSTEM ?= generic
ENVIRONMENT ?= generic
in the makefile which gives them default values.
Your output looks to be missing the all important output:
<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers
just to clarify, what actually got sent to g++
was -D -DWindows_NT
, i.e. define a preprocessor macro called -DWindows_NT
; which is of course not a valid identifier (similarly for -D -I.
)
Problem solved! I'm using Ctrl + Alt + E to open Exception Window, and I checked all throw checkbox. So the debuger can stop at the exactly the error code.
NSTimeInterval
is Double
do do it with extension. Example:
extension Double {
var formattedTime: String {
var formattedTime = "0:00"
if self > 0 {
let hours = Int(self / 3600)
let minutes = Int(truncatingRemainder(dividingBy: 3600) / 60)
formattedTime = String(hours) + ":" + (minutes < 10 ? "0" + String(minutes) : String(minutes))
}
return formattedTime
}
}
You can always escape the reserved keyword if you still want to make your query work!!
Just replace end with `end`
Here is the list of reserved keywords https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL
CREATE EXTERNAL TABLE moveProjects (cid string, `end` string, category string)
STORED BY 'org.apache.hadoop.hive.dynamodb.DynamoDBStorageHandler'
TBLPROPERTIES ("dynamodb.table.name" = "Projects",
"dynamodb.column.mapping" = "cid:cid,end:end,category:category");
That is the textarea
's job - for multiline text input. The input
won't do it; it wasn't designed to do it.
So use a textarea
. Besides their visual differences, they are accessed via JavaScript the same way (use value
property).
You can prevent newlines being entered via the input
event and simply using a replace(/\n/g, '')
.

select c.commonID, t1.commonID, t2.commonID
from Common c
left outer join Table1 t1 on t1.commonID = c.commonID
left outer join Table2 t2 on t2.commonID = c.commonID
where t1.commonID is null
and t2.commonID is null
I ran a few tests and here were my results w.r.t. @patmortech's answer and @rexem's comments.
If either Table1 or Table2 is not indexed on commonID, you get a table scan but @patmortech's query is still twice as fast (for a 100K row master table).
If neither are indexed on commonID, you get two table scans and the difference is negligible.
If both are indexed on commonID, the "not exists" query runs in 1/3 the time.

Second Thomas David Kehoe, with the following caveat --
If you are using node version manager (nvm), your global node modules will be stored under whatever version of node you are using at the time you saved the module.
So ~/.nvm/versions/node/{version}/lib/node_modules/
.
I would like to mention Python descriptor API that allows one customize object-to-attribute "communication". It is also noteworthy that, in Python, one is free to implement an alternative protocol via overriding the default given through the default implementation of the __getattribute__
method.
Let me give more details about the aforementioned.
Descriptors are regular classes with __get__
, __set__
and/or __delete__
methods.
When interpreter encounters something like anObj.anAttr
, the following is performed:
__getattribute__
method of anObj
is invoked__getattribute__
retrieves anAttr object from the class dict__get__
, __set__
or __delete__
callable objectsAs was mentioned, this is the default behavior. One is free to change the protocol by re-implementing __getattribute__
.
This technique is lot more powerful than decorators.
Either
In your cmd
console type the following:
set PATH=%PATH%;C:\Program Files (x86)\Git\bin
OR
Permanently set the path in your system's environment variables:
C:\Program Files (x86)\Git\bin;
As a rule of thumb, you should build a fat JAR using Maven (a JAR that contains both your code and all dependencies).
Then you can write a Dockerfile that matches your requirements (if you can build a fat JAR you would only need a base os, like CentOS, and the JVM).
This is what I use for a Scala app (which is Java-based).
FROM centos:centos7
# Prerequisites.
RUN yum -y update
RUN yum -y install wget tar
# Oracle Java 7
WORKDIR /opt
RUN wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/7u71-b14/server-jre-7u71-linux-x64.tar.gz
RUN tar xzf server-jre-7u71-linux-x64.tar.gz
RUN rm -rf server-jre-7u71-linux-x64.tar.gz
RUN alternatives --install /usr/bin/java java /opt/jdk1.7.0_71/bin/java 1
# App
USER daemon
# This copies to local fat jar inside the image
ADD /local/path/to/packaged/app/appname.jar /app/appname.jar
# What to run when the container starts
ENTRYPOINT [ "java", "-jar", "/app/appname.jar" ]
# Ports used by the app
EXPOSE 5000
This creates a CentOS-based image with Java7. When started, it will execute your app jar.
The best way to deploy it is via the Docker Registry, it's like a Github for Docker images.
You can build an image like this:
# current dir must contain the Dockerfile
docker build -t username/projectname:tagname .
You can then push an image in this way:
docker push username/projectname # this pushes all tags
Once the image is on the Docker Registry, you can pull it from anywhere in the world and run it.
See Docker User Guide for more informations.
Something to keep in mind:
You could also pull your repository inside an image and build the jar as part of the container execution, but it's not a good approach, as the code could change and you might end up using a different version of the app without notice.
Building a fat jar removes this issue.
install pip, securely download get-pip.py

On Windows, to get Pandas running,follow the step given in following link
https://github.com/svaksha/PyData-Workshop-Sprint/wiki/windows-install-pandas
May be a little late but the following solution happened very useful in my case.
In a way all you need to do is add to your ListView a Footer
and create for it addOnLayoutChangeListener
.
http://developer.android.com/reference/android/widget/ListView.html#addFooterView(android.view.View)
For example:
ListView listView1 = (ListView) v.findViewById(R.id.dialogsList); // Your listView
View loadMoreView = getActivity().getLayoutInflater().inflate(R.layout.list_load_more, null); // Getting your layout of FooterView, which will always be at the bottom of your listview. E.g. you may place on it the ProgressBar or leave it empty-layout.
listView1.addFooterView(loadMoreView); // Adding your View to your listview
...
loadMoreView.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
@Override
public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
Log.d("Hey!", "Your list has reached bottom");
}
});
This event fires once when a footer becomes visible and works like a charm.
In android studio: reduce minSDKversion. It will work...
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "healthcare.acceliant.trianz.com.myapplication"
minSdkVersion 11
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.1.1'
}
this
is the DOM element on which the event was hooked. this.id
is its ID. No need to wrap it in a jQuery instance to get it, the id
property reflects the attribute reliably on all browsers.
$("select").change(function() {
alert("Changed: " + this.id);
}
You're not doing this in your code sample, but if you were watching a container with several form elements, that would give you the ID of the container. If you want the ID of the element that triggered the event, you could get that from the event
object's target
property:
$("#container").change(function(event) {
alert("Field " + event.target.id + " changed");
});
(jQuery ensures that the change
event bubbles, even on IE where it doesn't natively.)
You can use .contents
:
>>> for hit in soup.findAll(attrs={'class' : 'MYCLASS'}):
... print hit.contents[6].strip()
...
THIS IS MY TEXT
getClass() has the restriction that objects are only equal to other objects of the same class, the same run time type, as illustrated in the output of below code:
class ParentClass{
}
public class SubClass extends ParentClass{
public static void main(String []args){
ParentClass parentClassInstance = new ParentClass();
SubClass subClassInstance = new SubClass();
if(subClassInstance instanceof ParentClass){
System.out.println("SubClass extends ParentClass. subClassInstance is instanceof ParentClass");
}
if(subClassInstance.getClass() != parentClassInstance.getClass()){
System.out.println("Different getClass() return results with subClassInstance and parentClassInstance ");
}
}
}
Outputs:
SubClass extends ParentClass. subClassInstance is instanceof ParentClass.
Different getClass() return results with subClassInstance and parentClassInstance.
Here are the changes I had to make to deliver PDFs for the django-publications app, using Django 1.10.6:
Used the same definitions for media directories as you, in settings.py
:
MEDIA_ROOT = '/home/user/mysite/media/'
MEDIA_URL = '/media/'
As provided by @thisisashwanipandey, in the project's main urls.py
:
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
# ... the rest of your URLconf goes here ...
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
and a modification of the answer provided by @r-allela, in settings.py
:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
# ... the rest of your context_processors goes here ...
'django.template.context_processors.media',
],
},
},
]
Most of the MVC helper methods have a XXXFor variant. They are intended to be used in conjunction with a concrete model class. The idea is to allow the helper to derive the appropriate "name" attribute for the form-input control based on the property you specify in the lambda. This means that you get to eliminate "magic strings" that you would otherwise have to employ to correlate the model properties with your views. For example:
Html.Hidden("Name", "Value")
Will result in:
<input id="Name" name="Name" type="hidden" value="Value">
In your controller, you might have an action like:
[HttpPost]
public ActionResult MyAction(MyModel model)
{
}
And a model like:
public class MyModel
{
public string Name { get; set; }
}
The raw Html.Hidden
we used above will get correlated to the Name
property in the model. However, it's somewhat distasteful that the value "Name" for the property must be specified using a string ("Name"). If you rename the Name
property on the Model, your code will break and the error will be somewhat difficult to figure out. On the other hand, if you use HiddenFor
, you get protected from that:
Html.HiddenFor(x => x.Name, "Value");
Now, if you rename the Name
property, you will get an explicit runtime error indicating that the property can't be found. In addition, you get other benefits of static analysis, such as getting a drop-down of the members after typing x.

This answer is based on this excellent answer by 18446744073709551615. Their solution, though helpful, does not size the image icon with the surrounding text. It also doesn't set the icon colour to that of the surrounding text.
The solution below takes a white, square icon and makes it fit the size and colour of the surrounding text.
public class TextViewWithImages extends TextView {
private static final String DRAWABLE = "drawable";
/**
* Regex pattern that looks for embedded images of the format: [img src=imageName/]
*/

super(context, attrs, defStyle);
}
public TextViewWithImages(Context context, AttributeSet attrs) {
super(context, attrs);
}
public TextViewWithImages(Context context) {
super(context);
}
@Override
public void setText(CharSequence text, BufferType type) {
final Spannable spannable = getTextWithImages(getContext(), text, getLineHeight(), getCurrentTextColor());
super.setText(spannable, BufferType.SPANNABLE);
}
private static Spannable getTextWithImages(Context context, CharSequence text, int lineHeight, int colour) {
final Spannable spannable = Spannable.Factory.getInstance().newSpannable(text);
addImages(context, spannable, lineHeight, colour);
return spannable;
}
private static boolean addImages(Context context, Spannable spannable, int lineHeight, int colour) {
final Pattern refImg = Pattern.compile(PATTERN);
boolean hasChanges = false;
final Matcher matcher = refImg.matcher(spannable);
while (matcher.find()) {
boolean set = true;
for (ImageSpan span : spannable.getSpans(matcher.start(), matcher.end(), ImageSpan.class)) {
if (spannable.getSpanStart(span) >= matcher.start()
&& spannable.getSpanEnd(span) <= matcher.end()) {
spannable.removeSpan(span);
} else {
set = false;
break;
}
}
final String resName = spannable.subSequence(matcher.start(1), matcher.end(1)).toString().trim();
final int id = context.getResources().getIdentifier(resName, DRAWABLE, context.getPackageName());
if (set) {
hasChanges = true;

}
}
How to use:
Simply embed references to the desired icons in the text. It doesn't matter whether the text is set programatically through textView.setText(R.string.string_resource);
or if it's set in xml.
To embed a drawable icon named example.png, include the following string in the text: [img src=example/]
.
For example, a string resource might look like this:
<string name="string_resource">This [img src=example/] is an icon.</string>
Try $.param
$.post("page.php",( $('#myForm').serialize()+'&'+$.param({ 'wordlist': wordlist })));
LEFT JOIN
and RIGHT JOIN
are types of OUTER JOIN

INNER JOIN
is the default -- rows from both tables must match the join condition.
When you copying your device token, it might copying the space, double check you have copied the correct token
To get the public key you can simply do:
public static PublicKey getPublicKeyFromCertFile(final String certfile){
return new X509CertImpl(new FileInputStream(new File(certfile))).getPublicKey();
To get the private key is trickier, you can:
public static PrivateKey getPrivateKeyFromKeyFile(final String keyfile){
try {
Process p;
p = Runtime.getRuntime().exec("openssl pkcs8 -nocrypt -topk8 -inform PEM " +
"-in " + keyfile + " -outform DER -out " + keyfile + ".der");
p.waitFor();
System.out.println("Command executed" + (p.exitValue() == 0 ? " successfully" : " with error" ));
} catch ( IOException | InterruptedException e) {
e.printStackTrace();
System.exit(1);
}
PrivateKey myPrivKey = null;
try {
byte[] keyArray = Files.readAllBytes(Paths.get(keyfile + ".der"));
PKCS8EncodedKeySpec keySpec = new PKCS8EncodedKeySpec(keyArray);
KeyFactory keyFactory = KeyFactory.getInstance("RSA");
myPrivKey = keyFactory.generatePrivate(keySpec);
} catch (IOException | NoSuchAlgorithmException | InvalidKeySpecException e){
e.printStackTrace();
System.exit(1);
}
return myPrivKey;
}
It escapes a string that cannot be passed to XML as usual:
Example:
The string contains "&" in it.
You can not:
<FL val="Company Name">Dolce & Gabbana</FL>
Therefore, you must use CDATA:
<FL val="Company Name"> <![CDATA["Dolce & Gabbana"]]> </FL>
For EF 6
using System.Data.Entity;
query.Include(x => x.Collection.Select(y => y.Property))
Make sure to add using System.Data.Entity;
to get the version of Include
that takes in a lambda.
For EF Core
Use the new method ThenInclude
query.Include(x => x.Collection)
.ThenInclude(x => x.Property);
One way would be with sed
. For example:
echo $name | sed -e 's?http://www\.??'
Normally the sed
regular expressions are delimited by `/', but you can use '?' since you're searching for '/'. Here's another bash trick. @DigitalTrauma's answer reminded me that I ought to suggest it. It's similar:
echo ${name#http://www.}
(DigitalTrauma also gets credit for reminding me that the "http://" needs to be handled.)

To repost:
After searching through many solutions I decided to blog about how to sort in jquery. In summary, steps to sort jquery "array-like" objects by data attribute...
Html
<div class="item" data-order="2">2</div> <div class="item" data-order="1">1</div> <div class="item" data-order="4">4</div> <div class="item" data-order="3">3</div>
Plain jquery selector
$('.item');
[<div class="item" data-order="2">2</div>, <div class="item" data-order="1">1</div>, <div class="item" data-order="4">4</div>, <div class="item" data-order="3">3</div> ]
Lets sort this by data-order
function getSorted(selector, attrName) { return $($(selector).toArray().sort(function(a, b){ var aVal = parseInt(a.getAttribute(attrName)), bVal = parseInt(b.getAttribute(attrName)); return aVal - bVal; })); }
> getSorted('.item', 'data-order')
[<div class="item" data-order="1">1</div>, <div class="item" data-order="2">2</div>, <div class="item" data-order="3">3</div>, <div class="item" data-order="4">4</div> ]
Hope this helps!
Push object into your array. Try this:
export class FormComponent implements OnInit {
name: string;
empoloyeeID : number;
empList: Array<{name: string, empoloyeeID: number}> = [];
constructor() {}
ngOnInit() {}
onEmpCreate(){
console.log(this.name,this.empoloyeeID);
this.empList.push({ name: this.name, empoloyeeID: this.empoloyeeID });
this.name = "";
this.empoloyeeID = 0;
}
}
Parsing is the process of analyzing text made of a sequence of tokens to determine its grammatical structure with respect to a given (more or less) formal grammar.
The parser then builds a data structure based on the tokens. This data structure can then be used by a compiler, interpreter or translator to create an executable program or library.
(source: wikimedia.org)
If I gave you an english sentence, and asked you to break down the sentence into its parts of speech (nouns, verbs, etc.), you would be parsing the sentence.
That's the simplest explanation of parsing I can think of.
That said, parsing is a non-trivial computational problem. You have to start with simple examples, and work your way up to the more complex.
Or you could just use this to find out if it is NOT a decimal:
string.indexOf(".") == -1;
You need to use parentheses: myList.insert([1, 2, 3])
. When you leave out the parentheses, python thinks you are trying to access myList.insert
at position 1, 2, 3
, because that's what brackets are used for when they are right next to a variable.
For Converting a List into Pandas Core Data Frame, we need to use DataFrame Method from pandas Package.
There are Different Ways to Perform the Above Operation.
import pandas as pd
Data = pd.DataFrame(Column_Data)
Data.columns = ['Column_Name']
So, for the above mentioned issue, the code snippet is
import pandas as pd
Content = ['Thanks You',
'Its fine no problem',
'Are you sure']
Data = pd.DataFrame({'Text': Content})
You should reference System.Web and call:
HttpContext.Current.Server.MapPath(...)
As stated above, there are a couple of different problems possible. What we found is that the .DLL for the WCF library had been added as a reference to the client project. This, in turn, created problems with resolving the objects and thus caused the files to be "emptied" by code generation steps. While unchecking the use "Reuse Types..." can seem like an answer, it creates extra definitions of object types, which are proxies to the real types, in a new name space, which then causes all kinds of "compatibility" issues with the use of those types. Only if you really want to "hide" a type should you check this option.
Hiding the type would be appropriate when you don't want a "DLL" type dependency to "leak" into a project that you are trying to keep segregated from another. If the DLL for the WCF library project creeps into the client project references, then you will have this problem with all kinds of strange side effects since the type definitions are also in the DLL.
How I do:
# Remove python2
sudo apt purge -y python2.7-minimal
# You already have Python3 but
# don't care about the version
sudo ln -s /usr/bin/python3 /usr/bin/python
# Same for pip
sudo apt install -y python3-pip
sudo ln -s /usr/bin/pip3 /usr/bin/pip
# Confirm the new version of Python: 3
python --version
The book has a note how to find help on tag sets, e.g.:
nltk.help.upenn_tagset()
Others are probably similar. (Note: Maybe you first have to download tagsets
from the download helper's Models section for this)
Arrays are different than ArrayList
s, on which you could call add
. You'll need an index first. Declare i
before the for
loop. Then you can use an array access expression to assign the element to the array.
num[i] = s;
i++;
As others have mentioned, the NET::ERR_CERT_COMMON_NAME_INVALID
error is occurring because the generated certificate does not include the SAN (subjectAltName
) field.
RFC2818 has deprecated falling back to the commonName
field since May of 2000. The use of the subjectAltName
field has been enforced in Chrome since version 58 (see Chrome 58 deprecations).
OpenSSL accepts x509v3 configuration files to add extended configurations to certificates (see the subjectAltName field for configuration options).
I created a self-signed-tls bash script with straightforward options to make it easy to generate certificate authorities and sign x509 certificates with OpenSSL (valid in Chrome using the subjectAltName
field).
The script will guide you through a series of questions to include the necessary information (including the subjectAltName
field). You can reference the README.md for more details and options for automation.
Be sure to restart chrome after installing new certificates.

I've seen many answers but they seem confusing to me. Can't we just simply use Type Casting.
For ex:-
int s;
char i= '2';
s = (int) i;

The accepted answer is correct as asked, below answers the opposite question of developing Android on VS Code.
Extensions
Ultimately you can automate building and running your app on a device emulator by adding the function below to your $PATH
and running runDebugApp <module> <start activity>
from the integrated terminal:
# run android app
# usage runDebugApp [module] [fully qualified start activity com.package/com.package.MainActivity]
function runDebugApp(){
./gradlew -offline :"$1":installDebug && adb shell am start "$2" && adb logcat -d > logcat.log
}
There is definitively no way to do this with standard formulas. However, a crazy sort of answer can be found here. It still avoids VBA, and it will allow you to get your result dynamically.
First, make the formula that will generate your formula, but don't add the =
at the beginning!
Let us pretend that you have created this formula in cell B2
of Sheet1
, and you would like the formula to be evaluated in column c
.
Now, go to the Formulas tab, and choose "Define Name". Give it the name myResult
(or whatever you choose), and under Refers To, write =evaluate(Sheet1!$B2)
(note the $
)
Finally, go to C2
, and write =myResult
. Drag down, and... voila!
Iam confused a lot from morning whether it should be less than or greater than`
this can accept value less than "99999"
I think you answered it yourself... But it's valid when it's less than. Thus the following is incorrect:
}elseif($("#seats").val() < 99999){
alert("Not a valid Number");
}else{
You are saying if it's less than 99999, then it's not valid. You want to do the opposite:
}elseif($("#seats").val() >= 99999){
alert("Not a valid Number");
}else{
Also, since you have $("#seats")
twice, jQuery has to search the DOM twice. You should really be storing the value, or at least the DOM element in a variable. And some more of your code doesn't make much sense, so I'm going to make some assumptions and put it all together:
var seats = $("#seats").val();
var error = null;
if (seats == "") {
error = "Number is required";
} else {
var seatsNum = parseInt(seats);
if (isNaN(seatsNum)) {
error = "Not a valid number";
} else if (seatsNum >= 99999) {
error = "Number must be less than 99999";
}
}
if (error != null) {
alert(error);
} else {
alert("Valid number");
}
// If you really need setflag:
var setflag = error != null;
Here's a working sample: http://jsfiddle.net/LUY8q/
Swift 2 version
extension NSTimeInterval {
func toMM_SS() -> String {
let interval = self
let componentFormatter = NSDateComponentsFormatter()
componentFormatter.unitsStyle = .Positional
componentFormatter.zeroFormattingBehavior = .Pad
componentFormatter.allowedUnits = [.Minute, .Second]
return componentFormatter.stringFromTimeInterval(interval) ?? ""
}
}
let duration = 326.4.toMM_SS()
print(duration) //"5:26"
If you want to stop it in any moment ticker
ticker := time.NewTicker(500 * time.Millisecond)
go func() {
for range ticker.C {
fmt.Println("Tick")
}
}()
time.Sleep(1600 * time.Millisecond)
ticker.Stop()
If you do not want to stop it tick:
tick := time.Tick(500 * time.Millisecond)
for range tick {
fmt.Println("Tick")
}
a % b
in c++ default:
(-7/3) => -2
-2 * 3 => -6
so a%b => -1
(7/-3) => -2
-2 * -3 => 6
so a%b => 1
in python:
-7 % 3 => 2
7 % -3 => -2
in c++ to python:
(b + (a%b)) % b
There are two easy and safe rules which work not only in sh
but also bash
.
This works for all chars except single quote itself. To escape the single quote, close the quoting before it, insert the single quote, and re-open the quoting.
'I'\''m a s@fe $tring which ends in newline
'
sed command: sed -e "s/'/'\\\\''/g; 1s/^/'/; \$s/\$/'/"
This works for all characters except newline. For newline characters use single or double quotes. Empty strings must still be handled - replace with ""
\I\'\m\ \a\ \s\@\f\e\ \$\t\r\i\n\g\ \w\h\i\c\h\ \e\n\d\s\ \i\n\ \n\e\w\l\i\n\e"
"
sed command: sed -e 's/./\\&/g; 1{$s/^$/""/}; 1!s/^/"/; $!s/$/"/'
.
There's an easy safe set of characters, like [a-zA-Z0-9,._+:@%/-]
, which can be left unescaped to keep it more readable
I\'m\ a\ s@fe\ \$tring\ which\ ends\ in\ newline"
"
sed command: LC_ALL=C sed -e 's/[^a-zA-Z0-9,._+@%/-]/\\&/g; 1{$s/^$/""/}; 1!s/^/"/; $!s/$/"/'
.
Note that in a sed program, one can't know whether the last line of input ends with a newline byte (except when it's empty). That's why both above sed commands assume it does not. You can add a quoted newline manually.
Note that shell variables are only defined for text in the POSIX sense. Processing binary data is not defined. For the implementations that matter, binary works with the exception of NUL bytes (because variables are implemented with C strings, and meant to be used as C strings, namely program arguments), but you should switch to a "binary" locale such as latin1.
(You can easily validate the rules by reading the POSIX spec for sh
. For bash, check the reference manual linked by @AustinPhillips)
You can use the @NamedEntityGraph
annotation to your entity to create a loadable query that set which collections you want to load on your query.
The main advantage of this choice is that hibernate makes one single query to retrieve the entity and its collections and only when you choose to use this graph, like this:
Entity configuration
@Entity
@NamedEntityGraph(name = "graph.myEntity.addresesAndPersons",
attributeNodes = {
@NamedAttributeNode(value = "addreses"),
@NamedAttributeNode(value = "persons"
})
Usage
public MyEntity findNamedGraph(Object id, String namedGraph) {
EntityGraph<MyEntity> graph = em.getEntityGraph(namedGraph);
Map<String, Object> properties = new HashMap<>();
properties.put("javax.persistence.loadgraph", graph);
return em.find(MyEntity.class, id, properties);
}
Use this
Facebook - "com.facebook.katana"
Twitter - "com.twitter.android"
Instagram - "com.instagram.android"
Pinterest - "com.pinterest"
SharingToSocialMedia("com.facebook.katana")
public void SharingToSocialMedia(String application) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, bmpUri);
boolean installed = checkAppInstall(application);
if (installed) {
intent.setPackage(application);
startActivity(intent);
} else {
Toast.makeText(getApplicationContext(),
"Installed application first", Toast.LENGTH_LONG).show();
}
}
private boolean checkAppInstall(String uri) {
PackageManager pm = getPackageManager();
try {
pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
return true;
} catch (PackageManager.NameNotFoundException e) {
}
return false;
}
You can always clear a specific file by doing the following:
If not:
This is very handy if you have resources that are in frames and CTRL+F5
is not force refreshing them.
You should write :
long startTime = System.nanoTime();
long estimatedTime = System.nanoTime() - startTime;
Assigning the endTime in a variable might cause a few nanoseconds. In this approach you will get the exact elapsed time.
And then:
TimeUnit.SECONDS.convert(estimatedTime, TimeUnit.NANOSECONDS)
maybe there are some unmerged paths in your git repository that you have to resolve before stashing.
Check output of console.log(req)
or console.log(req.headers);
Use setTimeout()
instead. The callback would then be responsible for firing the next timeout, at which point you can increase or otherwise manipulate the timing.
Here's a generic function you can use to apply a "decelerating" timeout for ANY function call.
function setDeceleratingTimeout(callback, factor, times)
{
var internalCallback = function(tick, counter) {
return function() {
if (--tick >= 0) {
window.setTimeout(internalCallback, ++counter * factor);
callback();
}
}
}(times, 0);
window.setTimeout(internalCallback, factor);
};
// console.log() requires firebug
setDeceleratingTimeout(function(){ console.log('hi'); }, 10, 10);
setDeceleratingTimeout(function(){ console.log('bye'); }, 100, 10);
HashSet hs = new HashSet();
hs.addAll(arrayList);
arrayList.clear();
arrayList.addAll(hs);
I came across over the following post: http://blogs.msdn.com/b/raulperez/archive/2010/03/19/c-intellisense-options.aspx
The issue is that the "IntelliSense" option in c++ is disabled. This link explains about the IntelliSense database configuration and options.
After enabling the database you must close and reopen visual studio for autocomplete use 'ctrl'+'space'
In myy case the temporary files are already commited by previous actions, so modifying .gitignore will not affect those commited files..., you have to git rm files_to_be_ignored --cache
first, then commit, then DONE.
In Sourcetree: Just ignore a file in specified folder. Sourcetree will ask if you like to ignore all files in that folder. It's perfect!
You need to set up the remote repository on your client:
git remote add origin ssh://myserver.com/path/to/project
--SUBSTITUTION VARIABLES
-- these variables are used to store values TEMPorarily.
-- The values can be stored temporarily through
-- Single Ampersand (&)
-- Double Ampersand(&&)
-- The single ampersand substitution variable applies for each instance when the
--SQL statement is created or executed.
-- The double ampersand substitution variable is applied for all instances until
--that SQL statement is existing.
INSERT INTO Student (Stud_id, First_Name, Last_Name, Dob, Fees, Gender)
VALUES (&stud_Id, '&First_Name' ,'&Last_Name', '&Dob', &fees, '&Gender');
--Using double ampersand substitution variable
INSERT INTO Student (Stud_id,First_Name, Last_Name,Dob,Fees,Gender)
VALUES (&stud_Id, '&First_Name' ,'&Last_Name', '&Dob', &&fees,'&gender');
I always just convert a matrix:
x <- as.data.frame(matrix(nrow = 100, ncol = 10))
The problem is that your REGX pattern will only match the input "0-9".
To meet your requirement (0-9999999), you should rewrite your regx pattern:
ng-pattern="/^[0-9]{1,7}$/"
My example:
HTML:
<div ng-app ng-controller="formCtrl">
<form name="myForm" ng-submit="onSubmit()">
<input type="number" ng-model="price" name="price_field"
ng-pattern="/^[0-9]{1,7}$/" required>
<span ng-show="myForm.price_field.$error.pattern">Not a valid number!</span>
<span ng-show="myForm.price_field.$error.required">This field is required!</span>
<input type="submit" value="submit"/>
</form>
</div>
JS:
function formCtrl($scope){
$scope.onSubmit = function(){
alert("form submitted");
}
}
Here is a jsFiddle demo.
The only way to control the size of stack within process is start a new Thread
. But you can also control by creating a self-calling sub Java process with the -Xss
parameter.
public class TT {
private static int level = 0;
public static long fact(int n) {
level++;
return n < 2 ? n : n * fact(n - 1);
}
public static void main(String[] args) throws InterruptedException {
Thread t = new Thread(null, null, "TT", 1000000) {
@Override
public void run() {
try {
level = 0;
System.out.println(fact(1 << 15));
} catch (StackOverflowError e) {
System.err.println("true recursion level was " + level);
System.err.println("reported recursion level was "
+ e.getStackTrace().length);
}
}
};
t.start();
t.join();
try {
level = 0;
System.out.println(fact(1 << 15));
} catch (StackOverflowError e) {
System.err.println("true recursion level was " + level);
System.err.println("reported recursion level was "
+ e.getStackTrace().length);
}
}
}
@amitchhajer 's post works for GNU tar. If someone finds this post and needs it to work on a NON GNU

To expand the archive:

It's a sample using Generic Types.
public T GetAnything<T>() where T : class, new()
=> new T();
And you'll use this method calling this way:
var hello = GetAnything<Hello>();
In this case, you can use an interface to specify a type to pass as parameter.
public T GetAnything<T>() where T : ISomeInterface, new()
=> new T();
You must have a parameterless construtor in each class to use new() constraint.
Follow the full sample:
internal sealed class Program
{
private static void Main(string[] args)
{
GetAnything<Hello>().Play();
GetAnything<Radio>().Play();
GetAnything<Computer>().Play();
}
private static T GetAnything<T>() where T : ISomeInterface, new()
=> new T();
}
internal interface ISomeInterface
{
void Play();
}
internal sealed class Hello : ISomeInterface
{
// parameterless constructor.
public Hello() { }
public void Play() => Console.WriteLine("Saying hello!");
}
internal sealed class Radio : ISomeInterface
{
// parameterless constructor.
public Radio() { }
public void Play() => Console.WriteLine("Playing radio!");
}
internal sealed class Computer : ISomeInterface
{
// parameterless constructor.
public Computer() { }
public void Play() => Console.WriteLine("Playing from computer!");
}
It's just a principle about exposure APIs.
Using python, It's a good idea to avoid exposure API in outer space(module or class), function is a good encapsulation place.
It could be a good idea. when you ensure
Even though, Abuse this technique may cause problems and implies a design flaw.
Just from my exp, Maybe misunderstand your question.
You can add an auto generated id field in the table and select by this id
SELECT * FROM CUSTOMER WHERE CUSTOMER_ID = 3;
If you add:
<meta http-equiv="content-type" content="text/plain; charset=UTF-8"/>
in the head of the document it will start working as expected:
<script type="text/javascript">
var tableToExcel = (function() {
var uri = 'data:application/vnd.ms-excel;base64,'
, template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--><meta http-equiv="content-type" content="text/plain; charset=UTF-8"/></head><body><table>{table}</table></body></html>'
, base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
, format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
return function(table, name) {

The content length is just a HTTP header. You cannot trust it. Just read everything you can from the stream.
Available is definitely wrong. It's just the number of bytes that can be read without blocking.
Another issue is your resource handling. Closing the stream has to happen in any case. try/catch/finally will do that.
You cannot read text strings with csvread. Here is another solution:
fid1 = fopen('test.csv','r'); %# open csv file for reading
fid2 = fopen('new.csv','w'); %# open new csv file
while ~feof(fid1)
line = fgets(fid1); %# read line by line
A = sscanf(line,'%*[^,],%f,%f'); %# sscanf can read only numeric data :(
if A(2)<4.185 %# test the values
fprintf(fid2,'%s',line); %# write the line to the new file
end
end
fclose(fid1);
fclose(fid2);

Okay, of course the question has been answered, but no-one seems to notice the third line of your code. It continuosly bugged me.
<?php
mysqli_connect("localhost","root","","web_table");
mysql_select_db("web_table") or die(mysql_error());
for some reason, you made a mysqli connection to server, but you are trying to make a mysql connection to database.To get going, rather use
$link = mysqli_connect("localhost","root","","web_table");
mysqli_select_db ($link , "web_table" ) or die.....
or for where i began
<?php $connection = mysqli_connect("localhost","root","","web_table");
global $connection; // global connection to databases - kill it once you're done
or just query with a $connection parameter as the other argument like above. Get rid of that third line.
I don't know why but (for now) httpclient can be compiled only as a jar into the libs directory in your project. HttpCore works fine when it is included from mvn like that:
dependencies {
compile 'org.apache.httpcomponents:httpcore:4.4.3'
}
You can get some inspiration by reading an entrypoint.sh
script written by the contributors from MySQL that checks whether the specified variables were set.
As the script shows, you can pipe them with -a
, e.g.:
if [ -z "$MYSQL_ROOT_PASSWORD" -a -z "$MYSQL_ALLOW_EMPTY_PASSWORD" -a -z "$MYSQL_RANDOM_ROOT_PASSWORD" ]; then

Ctrl + . shows the menu. I find this easier to type than the alternative, Alt + Shift + F10.

Same holds true for this discussion as well.
It all depends on what you think is a unit , if you think UNIT is a class then you will only hit the public method. If you think UNIT is lines of code hitting private methods will not make you feel guilty.
If you want to invoke private methods you can use "PrivateObject" class and call the invoke method. You can watch this indepth youtube video ( http://www.youtube.com/watch?v=Vq6Gcs9LrPQ ) which shows how to use "PrivateObject" and also discusses if testing of private methods are logical or not.
I'd use <article>
for a text block that is totally unrelated to the other blocks on the page.
<section>
, on the other hand, would be a divider to separate a document which have are related to each other.
Now, i'm not sure what you have in your videos, newsfeed etc, but here's an example (there's no REAL right or wrong, just a guideline of how I use these tags):
<article>
<h1>People</h1>
<p>text about people</p>
<section>
<h1>fat people</h1>
<p>text about fat people</p>
</section>
<section>
<h1>skinny people</p>
<p>text about skinny people</p>
</section>
</article>
<article>
<h1>Cars</h1>
<p>text about cars</p>
<section>
<h1>Fast Cars</h1>
<p>text about fast cars</p>
</section>
</article>
As you can see, the sections are still relevant to each other, but as long as they're inside a block that groups them. Sections DONT have to be inside articles. They can be in the body of a document, but i use sections in the body, when the whole document is one article.
e.g.
<body>
<h1>Cars</h1>
<p>text about cars</p>
<section>
<h1>Fast Cars</h1>
<p>text about fast cars</p>
</section>
</body>
Hope this makes sense.
I was setting MIME type from .NET code as below -
File(generatedFileName, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")
My application generates excel using OpenXML SDK. This MIME type worked -
vnd.openxmlformats-officedocument.spreadsheetml.sheet
In my case, the problem was another. I was trying convert lists of lists of int to array. The problem was that there was one list with a different length than others. If you want to prove it, you must do:
print([i for i,x in enumerate(list) if len(x) != 560])
In my case, the length reference was 560.
This is an approach for Windows 10 (maybe for 7) and it changes the color scheme (theme) for cmd, npm terminal itself, not only console output for a particular app.
I found the working Windows plugin - Color Tool, which is presumably developed under Windows umbrella. A description is available at the link.
I added colortool directory into system environment path variable and now it is available whenever I start terminal (NodeJs command prompt, cmd).
You can add full text to an existing instance by changing the SQL Server program in Programs and Features. Follow the steps below. You might need the original disk or ISO for the installation to complete. (Per HotN's comment: If you have SQL Server Express, make sure it is SQL Server Express With Advanced Services.)
Directions:
On the Installation Type screen, select the appropriate SQL Server instance.
Advance through the rest of the wizard.

Using std::stringstream
as you have works perfectly fine, and do exactly what you wanted. If you're just looking for different way of doing things though, you can use std::find()
/std::find_first_of()
and std::string::substr()
.
Here's an example:
#include <iostream>
#include <string>
int main()
{
std::string s("Somewhere down the road");
std::string::size_type prev_pos = 0, pos = 0;
while( (pos = s.find(' ', pos)) != std::string::npos )
{
std::string substring( s.substr(prev_pos, pos-prev_pos) );
std::cout << substring << '\n';
prev_pos = ++pos;
}
std::string substring( s.substr(prev_pos, pos-prev_pos) ); // Last word
std::cout << substring << '\n';
return 0;
}
Better way is to use Queue class: http://docs.python.org/library/queue.html
Look at the good example code in the bottom of documentation page:
def worker():
while True:
item = q.get()
do_work(item)
q.task_done()
q = Queue()
for i in range(num_worker_threads):
t = Thread(target=worker)
t.daemon = True
t.start()
for item in source():
q.put(item)
q.join() # block until all tasks are done
For i As Integer = 0 To 100
bool = False
For j As Integer = 0 To 100
If check condition Then
'if condition match
bool = True
Exit For 'Continue For
End If
Next
If bool = True Then Continue For
Next
Hey If you want to print selected area or div ,Try This.
<style type="text/css">
@media print
{
body * { visibility: hidden; }
.div2 * { visibility: visible; }
.div2 { position: absolute; top: 40px; left: 30px; }
}
</style>
Hope it helps you
try putting username in double quote "username", somehow that fixed for me.
XRegExp has an escape function:
XRegExp.escape('Escaped? <.>');
// -> 'Escaped\?\ <\.>'
More on: http://xregexp.com/api/#escape
You could detect position of the mouse pointer and then move the web page (with body position relative) so they hover over what you want them to click.
For an example you can paste this code on the current page in your browser console (and refresh afterwards)
var upvote_position = $('#answer-12878316').position();
$('body').mousemove(function (event) {
$(this).css({
position: 'relative',
left: (event.pageX - upvote_position.left - 22) + 'px',
top: (event.pageY - upvote_position.top - 35) + 'px'
});
});
LocalDate.parse(
"01-23-2017" ,
DateTimeFormatter.ofPattern( "MM-dd-uuuu" )
)
I have a java.util.Date in the format yyyy-mm-dd
As other mentioned, the Date
class has no format. It has a count of milliseconds since the start of 1970 in UTC. No strings attached.
The other Answers use troublesome old legacy date-time classes, now supplanted by the java.time classes.
If you have a java.util.Date
, convert to a Instant
object. The Instant
class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).
Instant instant = myUtilDate.toInstant();
The other Answers ignore the crucial issue of time zone. Determining a date requires a time zone. For any given moment, the date varies around the globe by zone. A few minutes after midnight in Paris France is a new day, while still “yesterday” in Montréal Québec.
Define the time zone by which you want context for your Instant
.
ZoneId z = ZoneId.of( "America/Montreal" );
Apply the ZoneId
to get a ZonedDateTime
.
ZonedDateTime zdt = instant.atZone( z );
LocalDate
If you only care about the date without a time-of-day, extract a LocalDate
.
LocalDate localDate = zdt.toLocalDate();
To generate a string in standard ISO 8601 format, YYYY-MM-DD, simply call toString
. The java.time classes use the standard formats by default when generating/parsing strings.
String output = localDate.toString();
2017-01-23
If you want a MM-DD-YYYY format, define a formatting pattern.
DateTimeFormatter f = DateTimeFormatter.ofPattern( "MM-dd-uuuu" );
String output = localDate.format( f );
Note that the formatting pattern codes are case-sensitive. The code in the Question incorrectly used mm
(minute of hour) rather than MM
(month of year).
Use the same DateTimeFormatter
object for parsing. The java.time classes are thread-safe, so you can keep this object around and reuse it repeatedly even across threads.
LocalDate localDate = LocalDate.parse( "01-23-2017" , f );
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
This code can be used with timezone
javascript:
let minToHm = (m) => {_x000D_
let h = Math.floor(m / 60);_x000D_
h += (h < 0) ? 1 : 0;_x000D_
let m2 = Math.abs(m % 60);_x000D_
m2 = (m2 < 10) ? '0' + m2 : m2;_x000D_
return (h < 0 ? '' : '+') + h + ':' + m2;_x000D_
}_x000D_
_x000D_
console.log(minToHm(210)) // "+3:30"_x000D_
console.log(minToHm(-210)) // "-3:30"_x000D_
console.log(minToHm(0)) // "+0:00"
_x000D_
minToHm(210)
"+3:30"
minToHm(-210)
"-3:30"
minToHm(0)
"+0:00"
You have to include the expression for your calculated column:
SELECT
ColumnA,
ColumnB,
ColumnA + ColumnB AS calccolumn1
(ColumnA + ColumnB) / ColumnC AS calccolumn2
This worked for me!
String amount= "123.0000";
String.Format("{0:0.##}", amount); // "123.00"
Your problem arises from the fact that $i
has a blank value when your statement fails. Always quote your variables when performing comparisons if there is the slightest chance that one of them may be empty, e.g.:
if [ "$i" -ge 2 ] ; then
...
fi
This is because of how the shell treats variables. Assume the original example,
if [ $i -ge 2 ] ; then ...
The first thing that the shell does when executing that particular line of code is substitute the value of $i
, just like your favorite editor's search & replace function would. So assume that $i
is empty or, even more illustrative, assume that $i
is a bunch of spaces! The shell will replace $i
as follows:
if [ -ge 2 ] ; then ...
Now that variable substitutions are done, the shell proceeds with the comparison and.... fails because it cannot see anything intelligible to the left of -gt
. However, quoting $i
:
if [ "$i" -ge 2 ] ; then ...
becomes:
if [ " " -ge 2 ] ; then ...
The shell now sees the double-quotes, and knows that you are actually comparing four blanks to 2 and will skip the if
.
You also have the option of specifying a default value for $i
if $i
is blank, as follows:
if [ "${i:-0}" -ge 2 ] ; then ...
This will substitute the value 0 instead of $i
is $i
is undefined. I still maintain the quotes because, again, if $i
is a bunch of blanks then it does not count as undefined, it will not be replaced with 0, and you will run into the problem once again.
Please read this when you have the time. The shell is treated like a black box by many, but it operates with very few and very simple rules - once you are aware of what those rules are (one of them being how variables work in the shell, as explained above) the shell will have no more secrets for you.
Another way to do this is by using event listeners, here how you use them:
document.addEventListener("DOMContentLoaded", function() {
you_function(...);
});
Explanation:
DOMContentLoaded It means when the DOM Objects of the document are fully loaded and seen by JavaScript, also this could have been "click", "focus"...
function() Anonymous function, will be invoked when the event occurs.
I see you have all the settings right. You just need to end the local web server and start it again with
php artisan serve
Everytime you change your .env
file, you need tor restart the server for the new options to take effect.
Or clear and cache your configuration with
php artisan config:cache

In AsyncTask in the method:
@Override
protected void onPreExecute()
{
progressbar_view.setVisibility(View.VISIBLE);
// your code
}
And in onPostExecute:
@Override
protected void onPostExecute(String s)
{
progressbar_view.setVisibility(View.GONE);
//your code
}
I think you want to set
tableView.alwaysBounceVertical = NO;
The MOST CORRECT answer to your question is...
#content > div:first-of-type { /* css */ }
This will apply the CSS to the first div that is a direct child of #content (which may or may not be the first child element of #content)
Another option:
#content > div:nth-of-type(1) { /* css */ }
I'm surprised that predicates weren't the first choice as you typically know what element(s) you will next interact with on the page you're waiting to load. My approach has always been to build out predicates/functions like waitForElementByID(String id)
and waitForElemetVisibleByClass(String className)
, etc. and then use and reuse these wherever I need them, be it for a page load or page content change I'm waiting on.
For example,
In my test class:
driverWait.until(textIsPresent("expectedText");
In my test class parent:
protected Predicate<WebDriver> textIsPresent(String text){
final String t = text;
return new Predicate<WebDriver>(){
public boolean apply(WebDriver driver){
return isTextPresent(t);
}
};
}
protected boolean isTextPresent(String text){
return driver.getPageSource().contains(text);
}
Though this seems like a lot, it takes care of checking repeatedly for you and the interval for how often to check can be set along with the ultimate wait time before timing out. Also, you will reuse such methods.
In this example, the parent class defined and initiated the WebDriver driver
and the WebDriverWait driverWait
.
I hope this helps.

Your debut
and fin
values are floating point values, not integers, because taille
is a float.
Make those values integers instead:
item = plateau[int(debut):int(fin)]
Alternatively, make taille
an integer:
taille = int(sqrt(len(plateau)))
You could use Array.prototype.filter()
in combination with Array.prototype.some()
.
Here is an example (assuming your arrays are stored in the variables result1
and result2
):
//Find values that are in result1 but not in result2
var uniqueResultOne = result1.filter(function(obj) {
return !result2.some(function(obj2) {
return obj.value == obj2.value;
});
});
//Find values that are in result2 but not in result1
var uniqueResultTwo = result2.filter(function(obj) {
return !result1.some(function(obj2) {
return obj.value == obj2.value;
});
});
//Combine the two arrays of unique entries
var result = uniqueResultOne.concat(uniqueResultTwo);
Traditionally, JS was intended for short, quick-running pieces of code. If you had major calculations going on, you did it on a server - the idea of a JS+HTML app that ran in your browser for long periods of time doing non-trivial things was absurd.
Of course, now we have that. But, it'll take a bit for browsers to catch up - most of them have been designed around a single-threaded model, and changing that is not easy. Google Gears side-steps a lot of potential problems by requiring that background execution is isolated - no changing the DOM (since that's not thread-safe), no accessing objects created by the main thread (ditto). While restrictive, this will likely be the most practical design for the near future, both because it simplifies the design of the browser, and because it reduces the risk involved in allowing inexperienced JS coders mess around with threads...
Why is that a reason not to implement multi-threading in Javascript? Programmers can do whatever they want with the tools they have.
So then, let's not give them tools that are so easy to misuse that every other website i open ends up crashing my browser. A naive implementation of this would bring you straight into the territory that caused MS so many headaches during IE7 development: add-on authors played fast and loose with the threading model, resulting in hidden bugs that became evident when object lifecycles changed on the primary thread. BAD. If you're writing multi-threaded ActiveX add-ons for IE, i guess it comes with the territory; doesn't mean it needs to go any further than that.
Two use cases where threadlocal variable can be used -
1- When we have a requirement to associate state with a thread (e.g., a user ID or Transaction ID). That usually happens with a web application that every request going to a servlet has a unique transactionID associated with it.
// This class will provide a thread local variable which
// will provide a unique ID for each thread
class ThreadId {
// Atomic integer containing the next thread ID to be assigned
private static final AtomicInteger nextId = new AtomicInteger(0);
// Thread local variable containing each thread's ID
private static final ThreadLocal<Integer> threadId =
ThreadLocal.<Integer>withInitial(()-> {return nextId.getAndIncrement();});
// Returns the current thread's unique ID, assigning it if necessary
public static int get() {
return threadId.get();
}
}
Note that here the method withInitial is implemented using lambda expression.
2- Another use case is when we want to have a thread safe instance and we don't want to use synchronization as the performance cost with synchronization is more. One such case is when SimpleDateFormat is used. Since SimpleDateFormat is not thread safe so we have to provide mechanism to make it thread safe.
public class ThreadLocalDemo1 implements Runnable {
// threadlocal variable is created
private static final ThreadLocal<SimpleDateFormat> dateFormat = new ThreadLocal<SimpleDateFormat>(){
@Override
protected SimpleDateFormat initialValue(){
System.out.println("Initializing SimpleDateFormat for - " + Thread.currentThread().getName() );
return new SimpleDateFormat("dd/MM/yyyy");
}
};
public static void main(String[] args) {
ThreadLocalDemo1 td = new ThreadLocalDemo1();
// Two threads are created
Thread t1 = new Thread(td, "Thread-1");
Thread t2 = new Thread(td, "Thread-2");
t1.start();
t2.start();
}
@Override
public void run() {
System.out.println("Thread run execution started for " + Thread.currentThread().getName());
System.out.println("Date formatter pattern is " + dateFormat.get().toPattern());
System.out.println("Formatted date is " + dateFormat.get().format(new Date()));
}
}
One millionaire has N cars. You want to get all (4) wheels.
One (1) query loads all the cars, but for each (N) car a separate query is submitted for loading wheels.
Costs:
Assume indexes fit into ram.
1 + N query parsing and planing + index searching AND 1 + N + (N * 4) plate access for loading payload.
Assume indexes don't fit into ram.
Additional costs in worst case 1 + N plate accesses for loading index.
Summary
Bottle neck is plate access (ca. 70 times per second random access on hdd) An eager join select would also access the plate 1 + N + (N * 4) times for payload. So if the indexes fit into ram - no problem, its fast enough because only ram operations involved.
check for this by calling the library jquery after the noconflict.js or that this calling more than once jquery library after the noconflict.js
As @deanchiu said it may happen when you move the whole project to another path or server.
But in my case I had no access to command line on server and running following commands BEFORE I upload my project helped me.
> php artisan route:clear
> php artisan config:clear
Yes.
Field f = Test.class.getDeclaredField("str");
f.setAccessible(true);//Very important, this allows the setting to work.
String value = (String) f.get(object);
Then you use the field object to get the value on an instance of the class.
Note that get method is often confusing for people. You have the field, but you don't have an instance of the object. You have to pass that to the get
method
The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date')
declare the date property like so: private _date: string;
. Also, make sure you are instantiating the model with the new
keyword. Lastly, access the property using regular dot notation.
Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :
let passcode = "secret passcode";
class Employee {
private _fullName: string;
get fullName(): string {
return this._fullName;
}
set fullName(newName: string) {
if (passcode && passcode == "secret passcode") {
this._fullName = newName;
}
else {
console.log("Error: Unauthorized update of employee!");
}
}
}
let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
console.log(employee.fullName);
}

This method may prevent recycling and should not be used on large data sets.
UPDATE 05.07.2019
If you are using RecyclerView
inside a ScrollView
, just change ScrollView
to androidx.core.widget.NestedScrollView
. Inside this view there is no need to pack RecyclerView
inside a RelativeLayout
.
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- other views -->
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<!-- other views -->
</LinearLayout>
</androidx.core.widget.NestedScrollView>
Finally found the solution for this problem.
All you need to do is wrap the RecyclerView
in a RelativeLayout
. Maybe there are other Views which may also work.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/list"

A lot of answers I see. This is mine, and I think quite useful if you are working on Mac.
I'm sure you know there are some "bundle" files (.app, .rtfd, .workflow, and so on). And looking at Finder's window they seem single files. But they are not. And $ ls
or $ find
see them as directories... So, unless you need list their contents as well, this works for me:
find . -not -name ".*" -not -name "." | egrep -v "\.rtfd/|\.app/|\.lpdf/|\.workflow/"
Of course this is for the working dir, and you could add other bundles' extensions (but always with a /
after them). Or any other extensions if not bundle's without the /
.
Rather interesting the ".lpdf/
" (multilingual pdf). It has normal ".pdf
" extension (!!) or none in Finder. This way you get (or it just counts 1 file) for this pdf
and not a bunch of stuff…
Look at the Doctrine API source-code :

Both forms of the meta charset declaration are equivalent and should work the same across browsers. But, there are a few things you need to remember when declaring your web files character-set as UTF-8:
Apache servers are configured to serve files in ISO-8859-1 by default, so you need to add the following line to your .htaccess
file:
AddDefaultCharset UTF-8
This will configure Apache to serve your files declaring UTF-8 encoding in the Content-Type response header, but your files must be saved in UTF-8 (without BOM) to begin with.
Notepad cannot save your files in UTF-8 without the BOM. A free editor that can is Notepad++. On the program menu bar, select "Encoding > Encode in UTF-8 without BOM". You can also open files and re-save them in UTF-8 using "Encoding > Convert to UTF-8 without BOM".
More on the Byte Order Mark (BOM) at Wikipedia.
I had the following configuration:
nginx
)And applied permissions correctly as @bgies suggested in the accepted answer. The problem in my case was the php-fpm's configured running user and group which was originally apache
.
If you're using NGINX with php-fpm, you should open php-fpm's config file:
nano /etc/php-fpm.d/www.config
And replace user
and group
options' value with one NGINX is configured to work with; in my case, both were nginx
:
...
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
; will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx
...
Save it and restart nginx and php-fpm services.
In the "Window" menu, open "Open Perspective" -> "Debug".

next() and nextLine() methods are associated with Scanner and is used for getting String inputs. Their differences are...
next() can read the input only till the space. It can't read two words separated by space. Also, next() places the cursor in the same line after reading the input.
nextLine() reads input including space between the words (that is, it reads till the end of line \n). Once the input is read, nextLine() positions the cursor in the next line.
Read article :Difference between next() and nextLine()
Replace your while loop with :
while(r.hasNext()) {
scan = r.next();
System.out.println(scan);
if(scan.length()==0) {continue;}
//treatment
}
Using hasNext()
and next()
methods will resolve the issue.
This is because Java Generics are implemented with Type Erasure.
Your methods would be translated, at compile time, to something like:
Method resolution occurs at compile time and doesn't consider type parameters. (see erickson's answer)
void add(Set ii);
void add(Set ss);
Both methods have the same signature without the type parameters, hence the error.
The best way I have found is to use jQuery JSON
On Window 10, the problem was with the semicolon ;
.
Go to edit the system environment variables
and delete the semicolon at the end of JAVA_HOME
value C:\Program Files\Java\jdk1.8.0_144
In other words, convert this C:\Program Files\Java\jdk1.8.0_12;
to C:\Program Files\Java\jdk1.8.0_12
You might have to delete your entry in the Windows Dialog and create a new one. If you ever had multiple entries and get the bigger Form view, Windows automatically inserts a ;
at the end of each entry, even if you only have one entry left.
Try this :
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
var res = Find(html);
}
public static List<LinkItem> Find(string file)
{
List<LinkItem> list = new List<LinkItem>();
// 1.
// Find all matches in file.
MatchCollection m1 = Regex.Matches(file, @"(<a.*?>.*?</a>)",
RegexOptions.Singleline);
// 2.
// Loop over each match.
foreach (Match m in m1)
{
string value = m.Groups[1].Value;
LinkItem i = new LinkItem();
// 3.
// Get href attribute.
Match m2 = Regex.Match(value, @"href=\""(.*?)\""",
RegexOptions.Singleline);
if (m2.Success)
{
i.Href = m2.Groups[1].Value;
}
// 4.
// Remove inner tags from text.
string t = Regex.Replace(value, @"\s*<.*?>\s*", "",
RegexOptions.Singleline);
i.Text = t;
list.Add(i);
}
return list;
}
public struct LinkItem
{
public string Href;
public string Text;
public override string ToString()
{
return Href + "\n\t" + Text;
}
}
}
Input:
string html = "<a href=\"www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a> 2.<a href=\"http://www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a> ";
Result:
[0] = {www.aaa.xx/xx.zz?id=xxxx&name=xxxx}
[1] = {http://www.aaa.xx/xx.zz?id=xxxx&name=xxxx}
Scraping HTML extracts important page elements. It has many legal uses for webmasters and ASP.NET developers. With the Regex type and WebClient, we implement screen scraping for HTML.
Another easy way:you can use a web browser
control for getting href
from tag a
,like this:(see my example)
public Form1()
{
InitializeComponent();
webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
}
private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.DocumentText = "<a href=\"www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a><a href=\"http://www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a><a href=\"https://www.aaa.xx/xx.zz?id=xxxx&name=xxxx\" ....></a><a href=\"www.aaa.xx/xx.zz/xxx\" ....></a>";
}
void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
List<string> href = new List<string>();
foreach (HtmlElement el in webBrowser1.Document.GetElementsByTagName("a"))
{
href.Add(el.GetAttribute("href"));
}
}
public static final String tryClob2String(final Object value)
{
final Clob clobValue = (Clob) value;
String result = null;
try
{
final long clobLength = clobValue.length();
if (clobLength < Integer.MIN_VALUE || clobLength > Integer.MAX_VALUE)
{
log.debug("CLOB size too big for String!");
}
else
{
result = clobValue.getSubString(1, (int) clobValue.length());
}
}
catch (SQLException e)
{
log.error("tryClob2String ERROR: {}", e);
}
finally
{
if (clobValue != null)
{
try
{
clobValue.free();
}
catch (SQLException e)
{
log.error("CLOB FREE ERROR: {}", e);
}
}
}
return result;
}
Specify NR
if you want to capture output from selected rows:
awk 'NR==1{print $1}' /etc/*release
An alternative (ugly) way of achieving the same would be:
awk '{print $1; exit}'
An efficient way of getting the first string from a specific line, say line 42, in the output would be:
awk 'NR==42{print $1; exit}'
In my case (Linux Mint 16 based on Ubuntu), I had to:
npm config delete https-proxy
, and also
clear the https_proxy
Bash environment parameter — oddly enough, although I cannot find this behavior documented anywhere, npm fallbacks to https_proxy
:
$ http_proxy='' https_proxy='' npm config get https-proxy
null
$ http_proxy='' xxhttps_proxy='' npm config get https-proxy
https://1.2.3.4:8080
I believe labels are inline, and so they don't take a width. Maybe try using "display: block" and going from there.
Here's an example of code which uses the UTL_FILE.PUT and UTL_FILE.PUT_LINE calls:
declare
fHandle UTL_FILE.FILE_TYPE;
begin
fHandle := UTL_FILE.FOPEN('my_directory', 'test_file', 'w');
UTL_FILE.PUT(fHandle, 'This is the first line');
UTL_FILE.PUT(fHandle, 'This is the second line');
UTL_FILE.PUT_LINE(fHandle, 'This is the third line');
UTL_FILE.FCLOSE(fHandle);
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('Exception: SQLCODE=' || SQLCODE || ' SQLERRM=' || SQLERRM);
RAISE;
end;
The output from this looks like:
This is the first lineThis is the second lineThis is the third line
Share and enjoy.
The following sequence of commands does remove every name from the current module:
>>> import sys
>>> sys.modules[__name__].__dict__.clear()
I doubt you actually DO want to do this, because "every name" includes all built-ins, so there's not much you can do after such a total wipe-out. Remember, in Python there is really no such thing as a "variable" -- there are objects, of many kinds (including modules, functions, class, numbers, strings, ...), and there are names, bound to objects; what the sequence does is remove every name from a module (the corresponding objects go away if and only if every reference to them has just been removed).
Maybe you want to be more selective, but it's hard to guess exactly what you mean unless you want to be more specific. But, just to give an example:
>>> import sys
>>> this = sys.modules[__name__]
>>> for n in dir():
... if n[0]!='_': delattr(this, n)
...
>>>
This sequence leaves alone names that are private or magical, including the __builtins__
special name which houses all built-in names. So, built-ins still work -- for example:
>>> dir()
['__builtins__', '__doc__', '__name__', '__package__', 'n']
>>>
As you see, name n
(the control variable in that for
) also happens to stick around (as it's re-bound in the for
clause every time through), so it might be better to name that control variable _
, for example, to clearly show "it's special" (plus, in the interactive interpreter, name _
is re-bound anyway after every complete expression entered at the prompt, to the value of that expression, so it won't stick around for long;-).
Anyway, once you have determined exactly what it is you want to do, it's not hard to define a function for the purpose and put it in your start-up file (if you want it only in interactive sessions) or site-customize file (if you want it in every script).
var objDiv = document.getElementById("divExample");
objDiv.scrollTop = objDiv.scrollHeight;
As has already been stated, you can use:
lemons && document.write("foo gave me a bar");
or
if (lemons) document.write("foo gave me a bar");
If, however, you wish to use the one line if
statement to short-circuit a function though, you'd need to go with the bracket-less version like so:
if (lemons) return "foo gave me a bar";
as
lemons && return "foo gave me a bar"; // does not work!
will give you a SyntaxError: Unexpected keyword 'return'
+1 means 2 days ago. It's rounded.
[Note: edited to modernize ggplot syntax]
Your example is not reproducible since there is no ex1221new
(there is an ex1221
in Sleuth2
, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot
. One advantage is that ggplot
works with data.frame
s directly.
You can set the labels with xlab()
and ylab()
, or make it part of the scale_*.*
call.
library("Sleuth2")
library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area() +
xlab("My x label") +
ylab("My y label") +
ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area("Nitrogen") +
scale_x_continuous("My x label") +
scale_y_continuous("My y label") +
ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs
function
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area() +
labs(size= "Nitrogen",
x = "My x label",
y = "My y label",
title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
which gives an identical figure to the one above.
All cookies are client and server
There is no difference. A regular cookie can be set server side or client side. The 'classic' cookie will be sent back with each request. A cookie that is set by the server, will be sent to the client in a response. The server only sends the cookie when it is explicitly set or changed, while the client sends the cookie on each request.
But essentially it's the same cookie.
But, behavior can change
A cookie is basically a name=value
pair, but after the value can be a bunch of semi-colon separated attributes that affect the behavior of the cookie if it is so implemented by the client (or server).
Those attributes can be about lifetime, context and various security settings.
HTTP-only (is not server-only)
One of those attributes can be set by a server to indicate that it's an HTTP-only cookie. This means that the cookie is still sent back and forth, but it won't be available in JavaScript. Do note, though, that the cookie is still there! It's only a built in protection in the browser, but if somebody would use a ridiculously old browser like IE5, or some custom client, they can actually read the cookie!
So it seems like there are 'server cookies', but there are actually not. Those cookies are still sent to the client. On the client there is no way to prevent a cookie from being sent to the server.
Alternatives to achieve 'only-ness'
If you want to store a value only on the server, or only on the client, then you'd need some other kind of storage, like a file or database on the server, or Local Storage on the client.

Here's an alternative solution without code. This VBA works in the Excel Formula Bar:
To extract the file name:
=RIGHT(A1,LEN(A1)-FIND("~",SUBSTITUTE(A1,"\","~",LEN(A1)-LEN(SUBSTITUTE(A1,"\","")))))
To extract the file path:
=MID(A1,1,LEN(A1)-LEN(MID(A1,FIND(CHAR(1),SUBSTITUTE(A1,"\",CHAR(1),LEN(A1)-LEN(SUBSTITUTE(A1,"\",""))))+1,LEN(A1))))
This may be the good solution for you: change the code like this very little change
.box{
position: relative;
}
.box:hover .hidden{
opacity: 1;
width:500px;
}
.box .hidden{
background: yellow;
height: 334px;
position: absolute;
top: 0;
left: 0;
width: 0;
opacity: 0;
transition: all 1s ease;
}
See demo here
I took Sebastian's answer and added a keyExtractor to it -
private <U, T> Set<T> findDuplicates(Collection<T> collection, Function<? super T,? extends U> keyExtractor) {
Map<U, T> uniques = new HashMap<>(); // maps unique keys to corresponding values
return collection.stream()
.filter(e -> uniques.put(keyExtractor.apply(e), e) != null)
.collect(Collectors.toSet());
}
You should use the express framework.
npm install express
and then
var express = require('express');
var app = express();
app.use(express.static(__dirname + '/public'));
app.listen(8080);
and then the URL localhost:8080/images/logo.gif should work.
For starters
rake db:rollback
will get you back one step
then
rake db:rollback STEP=n
Will roll you back n
migrations where n
is the number of recent migrations you want to rollback.

all of the answers above try to make spaces visible from within vim. If you really insist on having visible spaces as dots, there's another approach...
If it cannot be done in vim, change your font entirely. I copied the Ubuntu One Mono font and edited it using FontForge. Remember to change the font's fullname, family, preferred family, compatible full (in FontFoge it's under TTF Names in the font info), in order to have it as a separate font. Simply edit the space character to have a dot in the middle and save the font to ~/.fonts Now you can use it for your gvim or the entire terminal... I copied the "!" character, removed the line and moved the dot to the middle. It took a little more than 5 minutes...
Note: changing the space character (0x20) results in the inconvenience of having dots on the entire vim screen... (but it will separate the spaces from tabs...)
I have written an add-in for SSMS and this problem is fixed there. You can use one of 2 ways:
you can use "Copy current cell 1:1" to copy original cell data to clipboard:
http://www.ssmsboost.com/Features/ssms-add-in-copy-results-grid-cell-contents-line-with-breaks
Or, alternatively, you can open cell contents in external text editor (notepad++ or notepad) using "Cell visualizers" feature: http://www.ssmsboost.com/Features/ssms-add-in-results-grid-visualizers
(feature allows to open contents of field in any external application, so if you know that it is text - you use text editor to open it. If contents is binary data with picture - you select view as picture. Sample below shows opening a picture):
Simple answer is that you can't - you won't be able to check a for a file on their machine from an ASP website, as to do so would be a dangerous risk for them.
You have to give them a file upload control - and there's not much you can do with that control. For security reasons javascript can't really touch it.
<asp:FileUpload ID="FileUpload1" runat="server" />
They then pick a file to upload, and you have to deal with any empty file that they might send up server side.
UPDATE: this only tested with server side rendering ( universal Javascript ) here is my boilerplate.
With only file-loader you can load images dynamically - the trick is to use ES6 template strings so that Webpack can pick it up:
This will NOT work. :
const myImg = './cute.jpg'
<img src={require(myImg)} />
To fix this, just use template strings instead :
const myImg = './cute.jpg'
<img src={require(`${myImg}`)} />

Use summarise
in the dplyr
package:
library(dplyr)
summarise(df, Average = mean(col_name, na.rm = T))
note: dplyr
supports both summarise
and summarize
.
Using Native Query:
Query query = entityManager.createNativeQuery("SELECT projectId, projectName FROM projects");
List result = query.getResultList();
Probably you suspended the server by: ^Z
.
The four digital number that vim C:/Sites/folder/Pids/Server.pids
outputs is the process id.
You should kill -9 processid
, replacing the process id with the 4 numbers that vim (or other editor) outputed.
If you need to change a file just once. You should prefer making the change locally and build a new docker image with this file.
Say in a docker image, you need to change a file named myFile.xml under /path/to/docker/image/. So, you need to do.
FROM docker-repo:tag
ADD myFile.xml /path/to/docker/image/
Then build your own docker image with docker build -t docker-repo:v-x.x.x .
Then use your newly build docker image.
A slightly shorter version using reduce
:
things.stream()
.map(this::resolve)
.reduce(Optional.empty(), (a, b) -> a.isPresent() ? a : b );
You could also move the reduce function to a static utility method and then it becomes:
.reduce(Optional.empty(), Util::firstPresent );
