Well, the problem you have is wrong line ending/encoding for notepad. Notepad uses Windows' line endings - \r\n
and you use \n
.
This works in Mac as well you can use
df= pd.read_csv('Region_count.csv', encoding ='latin1')
You could also try to include md5-hash-sums or similar do determine whether there are any differences at all. Then, only compare files which have different hashes...
I really liked @gerard answer which is actually deserves to be the correct answer here. I made some improvements:
Here's the code:
'use strict'
const fs = require('fs'),
util = require('util'),
stream = require('stream'),
es = require('event-stream'),
parse = require("csv-parse"),
iconv = require('iconv-lite');
class CSVReader {
constructor(filename, batchSize, columns) {
this.reader = fs.createReadStream(filename).pipe(iconv.decodeStream('utf8'))
this.batchSize = batchSize || 1000
this.lineNumber = 0
this.data = []
this.parseOptions = {delimiter: '\t', columns: true, escape: '/', relax: true}
}
read(callback) {
this.reader
.pipe(es.split())
.pipe(es.mapSync(line => {
++this.lineNumber
parse(line, this.parseOptions, (err, d) => {
this.data.push(d[0])
})
if (this.lineNumber % this.batchSize === 0) {
callback(this.data)
}
})
.on('error', function(){
console.log('Error while reading file.')
})
.on('end', function(){
console.log('Read entirefile.')
}))
}
continue () {
this.data = []
this.reader.resume()
}
}
module.exports = CSVReader
So basically, here is how you will use it:
let reader = CSVReader('path_to_file.csv')
reader.read(() => reader.continue())
I tested this with a 35GB CSV file and it worked for me and that's why I chose to build it on @gerard's answer, feedbacks are welcomed.
Split nextLine() by this delimiter:
(?=([^\"]*\"[^\"]*\")*[^\"]*$)")
.
10_Random.txt
.int
before reading an int
. It is not safe to check with hasNextLine()
and then expect an int
with nextInt()
. You should use hasNextInt()
to check that there actually is an int
to grab. How strictly you choose to enforce the one integer per line rule is up to you, of course.Yes,
with open('filename.txt') as fp:
for line in fp:
print line
is the way to go.
It is not more verbose. It is more safe.
Using the following Bash template should allow you to read one value at a time from a file and process it.
while read name; do
# Do what you want to $name
done < filename
Try CLPP library. It's simple and flexible library for command line parameters parsing. Header-only and cross-platform. Uses ISO C++ and Boost C++ libraries only. IMHO it is easier than Boost.Program_options.
Library: http://sourceforge.net/projects/clp-parser
26 October 2010 - new release 2.0rc. Many bugs fixed, full refactoring of the source code, documentation, examples and comments have been corrected.
You can't get any faster if you want to use an existing API to read the lines. But reading larger chunks and manually find each new line in the read buffer would probably be faster.
For selecting all in visual: Type Esc to be sure yor are in normal mode
:0
type ENTER to go to the beginning of file
vG
Params contains the following three groups of parameters:
match '/user/:id'
in routes.rb will set params[:id]params[:controller]
and params[:action]
is always available and contains the current controller and actionI have looked through all above answers, all of them use third-party library to solve it. It's have a simple solution in Node's API. e.g
const fs= require('fs')
let stream = fs.createReadStream('<filename>', { autoClose: true })
stream.on('data', chunk => {
let row = chunk.toString('ascii')
}))
Solved my own problem. This line:
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
needs to be:
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));
or since Java 7:
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8));
If you are really about to work on multi-gigabyte text files then do not use PowerShell. Even if you find a way to read it faster processing of huge amount of lines will be slow in PowerShell anyway and you cannot avoid this. Even simple loops are expensive, say for 10 million iterations (quite real in your case) we have:
# "empty" loop: takes 10 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) {} }
# "simple" job, just output: takes 20 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) { $i } }
# "more real job": 107 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) { $i.ToString() -match '1' } }
UPDATE: If you are still not scared then try to use the .NET reader:
$reader = [System.IO.File]::OpenText("my.log")
try {
for() {
$line = $reader.ReadLine()
if ($line -eq $null) { break }
# process the line
$line
}
}
finally {
$reader.Close()
}
UPDATE 2
There are comments about possibly better / shorter code. There is nothing wrong with the original code with for
and it is not pseudo-code. But the shorter (shortest?) variant of the reading loop is
$reader = [System.IO.File]::OpenText("my.log")
while($null -ne ($line = $reader.ReadLine())) {
$line
}
Clean and Pythonic Way of Reading the Lines of a File Into a List
First and foremost, you should focus on opening your file and reading its contents in an efficient and pythonic way. Here is an example of the way I personally DO NOT prefer:
infile = open('my_file.txt', 'r') # Open the file for reading.
data = infile.read() # Read the contents of the file.
infile.close() # Close the file since we're done using it.
Instead, I prefer the below method of opening files for both reading and writing as it is very clean, and does not require an extra step of closing the file once you are done using it. In the statement below, we're opening the file for reading, and assigning it to the variable 'infile.' Once the code within this statement has finished running, the file will be automatically closed.
# Open the file for reading.
with open('my_file.txt', 'r') as infile:
data = infile.read() # Read the contents of the file into memory.
Now we need to focus on bringing this data into a Python List because they are iterable, efficient, and flexible. In your case, the desired goal is to bring each line of the text file into a separate element. To accomplish this, we will use the splitlines() method as follows:
# Return a list of the lines, breaking at line boundaries.
my_list = data.splitlines()
The Final Product:
# Open the file for reading.
with open('my_file.txt', 'r') as infile:
data = infile.read() # Read the contents of the file into memory.
# Return a list of the lines, breaking at line boundaries.
my_list = data.splitlines()
Testing Our Code:
A fost odatã ca-n povesti,
A fost ca niciodatã,
Din rude mãri împãrãtesti,
O prea frumoasã fatã.
print my_list # Print the list.
# Print each line in the list.
for line in my_list:
print line
# Print the fourth element in this list.
print my_list[3]
['A fost odat\xc3\xa3 ca-n povesti,', 'A fost ca niciodat\xc3\xa3,',
'Din rude m\xc3\xa3ri \xc3\xaemp\xc3\xa3r\xc3\xa3testi,', 'O prea
frumoas\xc3\xa3 fat\xc3\xa3.']
A fost odatã ca-n povesti, A fost ca niciodatã, Din rude mãri
împãrãtesti, O prea frumoasã fatã.
O prea frumoasã fatã.
Inspired by this post and by the Stack Overflow question that led me here -- Is it possible to insert multiple rows at a time in an SQLite database? -- I've posted my first Git repository:
https://github.com/rdpoor/CreateOrUpdate
which bulk loads an array of ActiveRecords into MySQL, SQLite or PostgreSQL databases. It includes an option to ignore existing records, overwrite them or raise an error. My rudimentary benchmarks show a 10x speed improvement compared to sequential writes -- YMMV.
I'm using it in production code where I frequently need to import large datasets, and I'm pretty happy with it.
If you need to handle newlines in diferent systems you can simply use the PHP predefined constant PHP_EOL (http://php.net/manual/en/reserved.constants.php) and simply use explode to avoid the overhead of the regular expression engine.
$lines = explode(PHP_EOL, $subject);
requests package works really well for simple ui as @Andrew Mao suggested
import requests
response = requests.get('http://lib.stat.cmu.edu/datasets/boston')
data = response.text
for i, line in enumerate(data.split('\n')):
print(f'{i} {line}')

I would think , in a large file scenario using a stream would be far more efficient, because memory consumption would be very small.
But your algorithm could alternate between using a stream and loading the entire thing in memory based on the file size. I wouldn't be surprised if one is only better than the other under certain criteria.
You can use Boost Tokenizer with escaped_list_separator.
escaped_list_separator parses a superset of the csv. Boost::tokenizer
This only uses Boost tokenizer header files, no linking to boost libraries required.
Here is an example, (see Parse CSV File With Boost Tokenizer In C++ for details or Boost::tokenizer
):
#include <iostream> // cout, endl
#include <fstream> // fstream
#include <vector>
#include <string>
#include <algorithm> // copy
#include <iterator> // ostream_operator
#include <boost/tokenizer.hpp>
int main()
{
using namespace std;
using namespace boost;
string data("data.csv");
ifstream in(data.c_str());
if (!in.is_open()) return 1;
typedef tokenizer< escaped_list_separator<char> > Tokenizer;
vector< string > vec;
string line;
while (getline(in,line))
{
Tokenizer tok(line);
vec.assign(tok.begin(),tok.end());
// vector now contains strings from one row, output to cout here
copy(vec.begin(), vec.end(), ostream_iterator<string>(cout, "|"));
cout << "\n----------------------" << endl;
}
}
public void saveUrl(final String filename, final String urlString)
throws MalformedURLException, IOException {
BufferedInputStream in = null;
FileOutputStream fout = null;
try {
in = new BufferedInputStream(new URL(urlString).openStream());
fout = new FileOutputStream(filename);
final byte data[] = new byte[1024];
int count;
while ((count = in.read(data, 0, 1024)) != -1) {
fout.write(data, 0, count);
}
} finally {
if (in != null) {
in.close();
}
if (fout != null) {
fout.close();
}
}
}
You'll need to handle exceptions, probably external to this method.

To the parent div add a height say 50px. In the child span, add the line-height: 50px; Now the text in the span will be vertically center. This worked for me.
And with Prototype:

I had to install RazorGenerator.Templating
to get it all to work. From the NuGet console, type:
Install-Package RazorGenerator.Templating
Try this...
This solution uses plain CSS1 with no Javascript and works in all browsers, old and new. When clicked, the child anchor
tag activates its active
pseudo-class event. It then simply hides itself, allowing the active
event to bubble up to the parent li
tag who then restyles himself and reveals his anchor child again with a new style. The child has styled the parent.
Using your example:
<ul>
<li class="listitem">
<a class="link" href="#">This is a Link</a>
</li>
</ul>
Now apply these styles with the active
pseudo-class on a
to restyle the parent li
tag when the link is clicked:
a.link {
display: inline-block;
color: white;
background-color: green;
text-decoration: none;
padding: 5px;
}
li.listitem {
display: inline-block;
margin: 0;
padding: 0;
background-color: transparent;
}
/* When this 'active' pseudo-class event below fires on click, it hides itself,
triggering the active event again on its parent which applies new styles to itself and its child. */
a.link:active {
display: none;
}
.listitem:active {
background-color: blue;
}
.listitem:active a.link {
display: inline-block;
background-color: transparent;
}
You should see the link with a green background now change to the list item's blue background on click.

Try this function in Excel:
Public Shared Function SPLITTEXT(Text As String, SplitAt As String, ReturnZeroBasedIndex As Integer) As String
Dim s() As String = Split(Text, SplitAt)
If ReturnZeroBasedIndex <= s.Count - 1 Then
Return s(ReturnZeroBasedIndex)
Else
Return ""
End If
End Function
You use it like this:
First Name (A1) | Last Name (A2)
Value in cell A1 = Michael Zomparelli
I want the last name in column A2.
=SPLITTEXT(A1, " ", 1)
The last param is the zero-based index you want to return. So if you split on the space char then index 0 = Michael and index 1 = Zomparelli
The above function is a .Net function, but can easily be converted to VBA.
Output size of sha1 is 160 bits. Which is 160/8 == 20 chars (if you use 8-bit chars) or 160/16 = 10 (if you use 16-bit chars).
Normally you can use None
, but you can also use objc.NULL
, e.g.
import objc
val = objc.NULL
Especially useful when working with C code in Python.
Also see: Python objc.NULL Examples
If you are using Laravel eloquent you may try this as well.
$result = self::select('*')
->with('user')
->where('subscriptionPlan', function($query) use($activated){
$query->where('activated', '=', $roleId);
})
->get();
Try this out, it works:
InputStream in_s =

If you get a Null Value Exception, try this (with class TopBrandData
):

Try it this way. Put the table name in quotes (``). beside put variable '".$xyz."'.
So your sql query will be like:
$sql = mysql_query("UPDATE `anstalld` SET mandag = "'.$mandag.'" WHERE namn =".$name)or die(mysql_error());
For some reason, radhoo's solution wouldn't work for me. When I used the following expression:
$query = "INSERT INTO uradmonitor (db_value1, db_value2) VALUES (".
(($val1=='')?"NULL":("'".$val1."'")) . ", ".
(($val2=='')?"NULL":("'".$val2."'")) .
")";
'null' (with quotes) was inserted instead of null without quotes, making it a string instead of an integer. So I finally tried:
$query = "INSERT INTO uradmonitor (db_value1, db_value2) VALUES (".
(($val1=='')? :("'".$val1."'")) . ", ".
(($val2=='')? :("'".$val2."'")) .
")";
The blank resulted in the correct null (unquoted) being inserted into the query.
POST variables should be accessible via the request object: HttpRequest.getParameterMap(). The exception is if the form is sending multipart MIME data (the FORM has enctype="multipart/form-data"). In that case, you need to parse the byte stream with a MIME parser. You can write your own or use an existing one like the Apache Commons File Upload API.
It's not a good way, but for me it seems the most simplest.
Add an anchor tag which contains the modal data-target and data-toggle, have an id associated with it. (Can be added mostly anywhere in the html view)
<a href="" data-toggle="modal" data-target="#myModal" id="myModalShower"></a>
Now,
Inside the angular controller, from where you want to trigger the modal just use
angular.element('#myModalShower').trigger('click');
This will mimic a click to the button based on the angular code and the modal will appear.
If you are using the actuator module, you can shutdown the application via JMX
or HTTP
if the endpoint is enabled.
add to application.properties
:
endpoints.shutdown.enabled=true
Following URL will be available:
/actuator/shutdown
- Allows the application to be gracefully shutdown (not enabled by default).
Depending on how an endpoint is exposed, the sensitive parameter may be used as a security hint.
For example, sensitive endpoints will require a username/password when they are accessed over HTTP
(or simply disabled if web security is not enabled).

i feel above logics for hover is incorrect. it just inverse when mouse hovers. i have used below code. it seems to work perfectly alright.
<div @mouseover="upHere = true" @mouseleave="upHere = false" >
<h2> Something Something </h2>
<some-component v-show="upHere"></some-component>
</div>
on vue instance
data : {
upHere : false
}
Hope that helps
Assembly language has no direct means of printing anything. Your assembler may or may not come with a library that supplies such a facility, otherwise you have to write it yourself, and it will be quite a complex function. You also have to decide where to print things - in a window, on the printer? In assembler, none of this is done for you.
Use [ngClass]
and conditionally apply class based on the id
.
In your HTML file:
<li>
<img [ngClass]="{'this-is-a-class': id === 1 }" id="1"
src="../../assets/images/1.jpg" (click)="addClass(id=1)"/>
</li>
<li>
<img [ngClass]="{'this-is-a-class': id === 2 }" id="2"
src="../../assets/images/2.png" (click)="addClass(id=2)"/>
</li>
In your TypeScript file:
addClass(id: any) {
this.id = id;
}
here is my code..
const input = MobileNumberComponent.find('input')
// when
input.props().onChange({target: {
id: 'mobile-no',
value: '1234567900'
}});
MobileNumberComponent.update()
const Footer = (loginComponent.find('Footer'))
expect(Footer.find('Buttons').props().disabled).equals(false)
I have update my DOM with componentname.update()
And then checking submit button validation(disable/enable) with length 10 digit.

If you are doing a config transform, you may also need to remove the following line from the relevant web.config file.
<compilation xdt:Transform="RemoveAttributes(debug)" />
Use:
<!-- unsupported by HTML5 -->
<div class="col-xs-1" align="center">
instead of
<div class="col-xs-1 center-block">
You can also use bootstrap 3 css:

<div class="col-xs-1 text-center">
Bootstrap 4 now has flex classes that will center the content:
<div class="d-flex justify-content-center">
<div>some content</div>
</div>
Note that by default it will be x-axis

is column
Here is an example how to run an Unix bash or Windows bat/cmd script from Java. Arguments can be passed on the script and output received from the script. The method accepts arbitrary number of arguments.
public static void runScript(String path, String... args) {
try {
String[] cmd = new String[args.length + 1];
cmd[0] = path;
int count = 0;
for (String s : args) {
cmd[++count] = args[count - 1];
}
Process process = Runtime.getRuntime().exec(cmd);
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));
try {
process.waitFor();
} catch (Exception ex) {
System.out.println(ex.getMessage());
}
while (bufferedReader.ready()) {
System.out.println("Received from script: " + bufferedReader.readLine());
}
} catch (Exception ex) {
System.out.println(ex.getMessage());
System.exit(1);
}

When running on Unix/Linux, the path must be Unix-like (with '/' as separator), when running on Windows - use '\'. Hier is an example of a bash script (test.sh) that receives arbitrary number of arguments and doubles every argument:
#!/bin/bash
counter=0
while [ $# -gt 0 ]
do
echo argument $((counter +=1)): $1
echo doubling argument $((counter)): $(($1+$1))
shift
done
When calling
runScript("path_to_script/test.sh", "1", "2")
on Unix/Linux, the output is:
Received from script: argument 1: 1
Received from script: doubling argument 1: 2
Received from script: argument 2: 2
Received from script: doubling argument 2: 4
Hier is a simple cmd Windows script test.cmd that counts number of input arguments:
@echo off
set a=0
for %%x in (%*) do Set /A a+=1
echo %a% arguments received
When calling the script on Windows
runScript("path_to_script\\test.cmd", "1", "2", "3")
The output is
Received from script: 3 arguments received
According to Mozilla Dev Network, placeholder
is not a valid attribute on a <select>
input.
Instead, add an option with an empty value
and the selected
attribute, as shown below. The empty value
attribute is mandatory to prevent the default behaviour which is to use the contents of the <option>
as the <option>
's value.
<select>
<option value="" selected>select your beverage</option>
<option value="tea">Tea</option>
<option value="coffee">Coffee</option>
<option value="soda">Soda</option>
</select>
In modern browsers, adding the required
attribute to the <select>
element will not allow the user to submit the form which the element is part of if the selected option has an empty value.
If you want to style the default option inside the list (which appears when clicking the element), there's a limited number of CSS properties that are well-supported. color
and background-color
are the 2 safest bets, other CSS properties are likely to be ignored.
In my option the best way (in HTML5) to mark the default option is using the custom data-*
attributes.1 Here's how to style the default option to be greyed out:
select option[data-default] {_x000D_
color: #888;_x000D_
}
_x000D_
<select>_x000D_
<option value="" selected data-default>select your beverage</option>_x000D_
<option value="tea">Tea</option>_x000D_
<option value="coffee">Coffee</option>_x000D_
<option value="soda">Soda</option>_x000D_
</select>
_x000D_
However, this will only style the item inside the drop-down list, not the value displayed on the input. If you want to style that with CSS, target your <select>
element directly. In that case, you can only change the style of the currently selected element at any time.2
If you wanted to make it slightly harder for the user to select the default item, you could set the display: none;
CSS rule on the <option>
, but remember that this will not prevent users from selecting it (using e.g. arrow keys/typing), this just makes it harder for them to do so.
1 This answer previously advised the use of a default
attribute which is non-standard and has no meaning on its own.
2 It's technically possible to style the select itself based on the selected value using JavaScript, but that's outside the scope of this question. This answer, however, covers this method.
CASE 1 : SQLite 3.25.0+
Only the Version 3.25.0 of SQLite supports renaming columns. If your device is meeting this requirement, things are quite simple. The below query would solve your problem:
ALTER TABLE "MyTable" RENAME COLUMN "OldColumn" TO "NewColumn";
CASE 2 : SQLite Older Versions
You have to follow a different Approach to get the result which might be a little tricky
For example, if you have a table like this:
CREATE TABLE student(Name TEXT, Department TEXT, Location TEXT)
And if you wish to change the name of the column Location
Step 1: Rename the original table:
ALTER TABLE student RENAME TO student_temp;
Step 2: Now create a new table student
with correct column name:
CREATE TABLE student(Name TEXT, Department TEXT, Address TEXT)
Step 3: Copy the data from the original table to the new table:
INSERT INTO student(Name, Department, Address) SELECT Name, Department, Location FROM student_temp;
Note: The above command should be all one line.
Step 4: Drop the original table:
DROP TABLE student_temp;
With these four steps you can manually change any SQLite table. Keep in mind that you will also need to recreate any indexes, viewers or triggers on the new table as well.
The way to define your routes in laravel 8 is either
// Using PHP callable syntax...
use App\Http\Controllers\HomeController;
Route::get('/', [HomeController::class, 'index']);
OR
// Using string syntax...
Route::get('/', 'App\Http\Controllers\HomeController@index');
A resource route becomes
// Using PHP callable syntax...
use App\Http\Controllers\HomeController;
Route::resource('/', HomeController::class);
This means that in laravel 8, there is no automatic controller declaration prefixing by default.
If you want to stick to the old way, then you need to add a namespace property in the
app\Providers\RouteServiceProvider.php
and activate in the routes method.
Follow this image instructions below:
Here an approach to have count distinct over multiple columns. Let's have some data:
data = {'CLIENT_CODE':[1,1,2,1,2,2,3],
'YEAR_MONTH':[201301,201301,201301,201302,201302,201302,201302],
'PRODUCT_CODE': [100,150,220,400,50,80,100]
}
table = pd.DataFrame(data)
table
CLIENT_CODE YEAR_MONTH PRODUCT_CODE
0 1 201301 100
1 1 201301 150
2 2 201301 220
3 1 201302 400
4 2 201302 50
5 2 201302 80
6 3 201302 100
Now, list the columns of interest and use groupby in a slightly modified syntax:
columns = ['YEAR_MONTH', 'PRODUCT_CODE']
table[columns].groupby(table['CLIENT_CODE']).nunique()
We obtain:
YEAR_MONTH PRODUCT_CODE CLIENT_CODE
1 2 3
2 2 3
3 1 1
I found something about JDK 1.0 and 1.1 and >= 1.2:
In JDK 1.0.x and 1.1.x the hashCode function for long Strings worked by sampling every nth character. This pretty well guaranteed you would have many Strings hashing to the same value, thus slowing down Hashtable lookup. In JDK 1.2 the function has been improved to multiply the result so far by 31 then add the next character in sequence. This is a little slower, but is much better at avoiding collisions. Source: http://mindprod.com/jgloss/hashcode.html
Something different, because you seem to need a number: How about using CRC32 or MD5 instead of hashcode and you are good to go - no discussions and no worries at all...
http://site.mockito.org/mockito/docs/1.10.19/org/mockito/Matchers.html
anyObject()
should fit your needs.
Also, you can always consider implementing hashCode()
and equals()
for the Bazoo
class. This would make your code example work the way you want.
I just used:
$('#source').prependTo('#destination');
Which I grabbed from here.
Vishal's example, however great, confuses when it comes to the file name, and I do not see the merit of redefing 'zipfile'.
Here is my example that downloads a zip that contains some files, one of which is a csv file that I subsequently read into a pandas DataFrame:
from StringIO import StringIO
from zipfile import ZipFile
from urllib import urlopen
import pandas
url = urlopen("https://www.federalreserve.gov/apps/mdrm/pdf/MDRM.zip")
zf = ZipFile(StringIO(url.read()))
for item in zf.namelist():
print("File in zip: "+ item)
# find the first matching csv file in the zip:
match = [s for s in zf.namelist() if ".csv" in s][0]
# the first line of the file contains a string - that line shall de ignored, hence skiprows
df = pandas.read_csv(zf.open(match), low_memory=False, skiprows=[0])
(Note, I use Python 2.7.13)
This is the exact solution that worked for me. I just tweaked it a little bit for Python 3 version by removing StringIO and adding IO library
from io import BytesIO
from zipfile import ZipFile
import pandas
import requests
url = "https://www.nseindia.com/content/indices/mcwb_jun19.zip"
content = requests.get(url)
zf = ZipFile(BytesIO(content.content))
for item in zf.namelist():
print("File in zip: "+ item)
# find the first matching csv file in the zip:
match = [s for s in zf.namelist() if ".csv" in s][0]
# the first line of the file contains a string - that line shall de ignored, hence skiprows
df = pandas.read_csv(zf.open(match), low_memory=False, skiprows=[0])
Set your css in the table cell to
white-space:pre-wrap;
document.body.innerHTML = 'First line\nSecond line\nThird line';
_x000D_
body{ white-space:pre-wrap; }
_x000D_
Maybe you can filter rows by possible columns like this :
DataRow[] filteredRows =
datatable.Select(string.Format("{0} LIKE '%{1}%'", columnName, value));
In general for AnInterface
and anInstance
of any class:
AnInterface.class.isAssignableFrom(anInstance.getClass());
Not entirely an answer to the original post, but a quick and dirty solution for posting a json-object to the server and dynamically generating a download.
Client side jQuery:
var download = function(resource, payload) {
$("#downloadFormPoster").remove();
$("<div id='downloadFormPoster' style='display: none;'><iframe name='downloadFormPosterIframe'></iframe></div>").appendTo('body');
$("<form action='" + resource + "' target='downloadFormPosterIframe' method='post'>" +
"<input type='hidden' name='jsonstring' value='" + JSON.stringify(payload) + "'/>" +
"</form>")
.appendTo("#downloadFormPoster")
.submit();
}
..and then decoding the json-string at the serverside and setting headers for download (PHP example):
$request = json_decode($_POST['jsonstring']), true);
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename=export.csv');
header('Pragma: no-cache');
If you want a minimalist method of converting a variable to a string for an inline expression type situation, ''+variablename
is the best I have golfed.
If 'variablename' is an object and you use the empty string concatenation operation, it will give the annoying [object Object]
, in which case you probably want Gary C.'s enormously upvoted JSON.stringify
answer to the posted question, which you can read about on Mozilla's Developer Network at the link in that answer at the top.
The Gradle build system for Android supports "resource shrinking": the automatic removal of resources that are unused, at build time, in the packaged app. In addition to removing resources in your project that are not actually needed at runtime, this also removes resources from libraries you are depending on if they are not actually needed by your application.
To enable this add the line shrinkResources true in your gradle file.
android {
...
buildTypes {
release {
minifyEnabled true //Important step
shrinkResources true
}
}
}
Check the official documentation here,
http://tools.android.com/tech-docs/new-build-system/resource-shrinking
There are two possible scenario, in my case I used 2nd point.
If you are facing this issue in production environment and you can easily deploy new code to the production then you can use of below solution.
You can add below line of code before making api call,
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; // .NET 4.5
If you cannot deploy new code and you want to resolve with the same code which is present in the production, then this issue can be done by changing some configuration setting file. You can add either of one in your config file.
<runtime>
<AppContextSwitchOverrides value="Switch.System.Net.DontEnableSchUseStrongCrypto=false"/>
</runtime>
or
<runtime>
<AppContextSwitchOverrides value="Switch.System.Net.DontEnableSystemDefaultTlsVersions=false"
</runtime>
http://localhost:(port number of phpmyadmin)/phpmyadmin/
For example: http://localhost:8080/phpmyadmin/
It works great!
The best way to do it without any headache is to use the
\tablefootnote
command from the tablefootnote
package. Add the following to your preamble:
\usepackage{tablefootnote}
It just works without the need of additional tricks.
Text inside an ifdef/endif
or ifndef/endif
pair will be left in or removed by the pre-processor depending on the condition. ifdef
means "if the following is defined" while ifndef
means "if the following is not defined".
So:
#define one 0
#ifdef one
printf("one is defined ");
#endif
#ifndef one
printf("one is not defined ");
#endif
is equivalent to:
printf("one is defined ");
since one
is defined so the ifdef
is true and the ifndef
is false. It doesn't matter what it's defined as. A similar (better in my opinion) piece of code to that would be:
#define one 0
#ifdef one
printf("one is defined ");
#else
printf("one is not defined ");
#endif
since that specifies the intent more clearly in this particular situation.
In your particular case, the text after the ifdef
is not removed since one
is defined. The text after the ifndef
is removed for the same reason. There will need to be two closing endif
lines at some point and the first will cause lines to start being included again, as follows:
#define one 0
+--- #ifdef one
| printf("one is defined "); // Everything in here is included.
| +- #ifndef one
| | printf("one is not defined "); // Everything in here is excluded.
| | :
| +- #endif
| : // Everything in here is included again.
+--- #endif
The other solutions are great for a single if
/ else
construct. However, ternary statements within list comprehensions are arguably difficult to read.
Using a function aids readability, but such a solution is difficult to extend or adapt in a workflow where the mapping is an input. A dictionary can alleviate these concerns:
row = [None, 'This', 'is', 'a', 'filler', 'test', 'string', None]
d = {None: '', 'filler': 'manipulated'}
res = [d.get(x, x) for x in row]
print(res)
['', 'This', 'is', 'a', 'manipulated', 'test', 'string', '']
There is no difference.
The Java Software Development Kit (Java SDK) used to be called the Java Development Kit (JDK) before the marketing department at Sun got crazy with the "tm" and terminology. For political reasons & for sanity, they call the meaningful names (jdk) & versions (1.2 / 1.3 / 1.4 1.5 / 1.6) "engineering" terms. The marketing terms are "Java2 platform" (aka jdk 1.2 thru 1.4) or Java5 (aka jdk 1.5) or Java6 (aka jdk1.6). I'm getting a headache just thinking about it.
If you want to reset it, then simple use:
<input type="reset" value="Reset" />
But beware, it will not clear out textboxes that have default value
. For example, if we have the following textboxes and by default, they have the following values:
<input id="textfield1" type="text" value="sample value 1" />
<input id="textfield2" type="text" value="sample value 2" />
So, to clear it out, compliment it with javascript:
function clearText()
{
document.getElementById('textfield1').value = "";
document.getElementById('textfield2').value = "";
}
And attach it to onclick
of the reset button:
<input type="reset" value="Reset" onclick="clearText()" />
Faced this exact issue. The problem resolved when i changed the Service="Namespace.ServiceName" tag in the Markup (right click xxxx.svc and select View Markup in visual studio) to match the namespace i used for my xxxx.svc.cs file
An alternative to get youtube channel ID by channel url without API:
function get_youtube_channel_ID($url){
$html = file_get_contents($url);
preg_match("'<meta itemprop=\"channelId\" content=\"(.*?)\"'si", $html, $match);
if($match && $match[1])
return $match[1];
}
I might be wrong but "find -name __" works fine for me. (Maybe it's just my phone.) If you just want to list all files, you can try
adb shell ls -R /
You probably need the root permission though.
Edit:
As other answers suggest, use ls
with grep
like this:
adb shell ls -Ral yourDirectory | grep -i yourString
eg.
adb shell ls -Ral / | grep -i myfile
-i
is for ignore-case. and /
is the root directory.
In my case it is Asp.Net Core 3.1 API. I changed the HTTP GET method from public ActionResult GetValidationRulesForField( GetValidationRulesForFieldDto getValidationRulesForFieldDto)
to public ActionResult GetValidationRulesForField([FromQuery] GetValidationRulesForFieldDto getValidationRulesForFieldDto)
and its working.

The target "all" is an example of a dummy target - there is nothing on disk called "all". This means that when you do a "make all", make always thinks that it needs to build it, and so executes all the commands for that target. Those commands will typically be ones that build all the end-products that the makefile knows about, but it could do anything.
Other examples of dummy targets are "clean" and "install", and they work in the same way.
If you haven't read it yet, you should read the GNU Make Manual, which is also an excellent tutorial.

Also you can use ss utility to dump sockets statistics.
To dump summary:
ss -s
Total: 91 (kernel 0)
TCP: 18 (estab 11, closed 0, orphaned 0, synrecv 0, timewait 0/0), ports 0
Transport Total IP IPv6
* 0 - -
RAW 0 0 0
UDP 4 2 2
TCP 18 16 2
INET 22 18 4
FRAG 0 0 0
To display all sockets:
ss -a
To display UDP sockets:
ss -u -a
To display TCP sockets:
ss -t -a
Here you can read ss man: ss
On our servers it was a problem with the system path. After upgrading PHP runtime (using installation directory whose name includes version number) and updating the path in system variable PATH
we were getting status 0x1
. System restart corrected the issue. Restarting Task Manager
service might have done it, too.
Like this
css
body {
background-color : #484848;
margin: 0;
padding: 0;
}
h1 {
color : #000000;
text-align : center;
font-family: "SIMPSON";
}
form {
width: 300px;
margin: 0 auto;
}
Just some minor modification to your code will do (with some var renaming for clarity) :
double sum = 0; //average will have decimal point
for(int i=0; i < args.length; i++){
//parse string to double, note that this might fail if you encounter a non-numeric string
//Note that we could also do Integer.valueOf( args[i] ) but this is more flexible
sum += Double.valueOf( args[i] );
}
double average = sum/args.length;
System.out.println(average );
Note that the loop can also be simplified:
for(String arg : args){
sum += Double.valueOf( arg );
}
Edit: the OP seems to want to use the args
array. This seems to be a String array, thus updated the answer accordingly.
Update:
As zoxqoj correctly pointed out, integer/double overflow is not taken care of in the code above. Although I assume the input values will be small enough to not have that problem, here's a snippet to use for really large input values:
BigDecimal sum = BigDecimal.ZERO;
for(String arg : args){
sum = sum.add( new BigDecimal( arg ) );
}
This approach has several advantages (despite being somewhat slower, so don't use it for time critical operations):
BigDecimal
might be bigger than what fits into a double
or long
.Make the following changes in your Registry and it should work:
1.) .NET Framework strong cryptography registry keys
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001
2.) Secure Channel (Schannel) TLS 1.2 registry keys
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001
Your class shoud look something like this:
class Something { int[] array; //global array, replace type of course void function1() { array = new int[10]; //let say you declare it here that will be 10 integers in size } void function2() { array[0] = 12; //assing value at index 0 to 12. } }
That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.
Perl versions 5.10 and later support subsidiary vertical and horizontal character classes, \v
and \h
, as well as the generic whitespace character class \s
The cleanest solution is to use the horizontal whitespace character class \h
. This will match tab and space from the ASCII set, non-breaking space from extended ASCII, or any of these Unicode characters
U+0009 CHARACTER TABULATION
U+0020 SPACE
U+00A0 NO-BREAK SPACE (not matched by \s)
U+1680 OGHAM SPACE MARK
U+2000 EN QUAD
U+2001 EM QUAD
U+2002 EN SPACE
U+2003 EM SPACE
U+2004 THREE-PER-EM SPACE
U+2005 FOUR-PER-EM SPACE
U+2006 SIX-PER-EM SPACE
U+2007 FIGURE SPACE
U+2008 PUNCTUATION SPACE
U+2009 THIN SPACE
U+200A HAIR SPACE
U+202F NARROW NO-BREAK SPACE
U+205F MEDIUM MATHEMATICAL SPACE
U+3000 IDEOGRAPHIC SPACE
The vertical space pattern \v
is less useful, but matches these characters
U+000A LINE FEED
U+000B LINE TABULATION
U+000C FORM FEED
U+000D CARRIAGE RETURN
U+0085 NEXT LINE (not matched by \s)
U+2028 LINE SEPARATOR
U+2029 PARAGRAPH SEPARATOR
There are seven vertical whitespace characters which match \v
and eighteen horizontal ones which match \h
. \s
matches twenty-three characters
All whitespace characters are either vertical or horizontal with no overlap, but they are not proper subsets because \h
also matches U+00A0 NO-BREAK SPACE, and \v
also matches U+0085 NEXT LINE, neither of which are matched by \s
Sometimes, I've wanted random strings that are semi-pronounceable, semi-memorable.
import random
def randomWord(length=5):
consonants = "bcdfghjklmnpqrstvwxyz"
vowels = "aeiou"
return "".join(random.choice((consonants, vowels)[i%2]) for i in range(length))
Then,
>>> randomWord()
nibit
>>> randomWord()
piber
>>> randomWord(10)
rubirikiro
To avoid 4-letter words, don't set length
to 4.

You are confusing a Mock
with a Spy
.
In a mock all methods are stubbed and return "smart return types". This means that calling any method on a mocked class will do nothing unless you specify behaviour.
In a spy the original functionality of the class is still there but you can validate method invocations in a spy and also override method behaviour.
What you want is
MyProcessingAgent mockMyAgent = Mockito.spy(MyProcessingAgent.class);
A quick example:
static class TestClass {
public String getThing() {
return "Thing";
}
public String getOtherThing() {
return getThing();
}
}
public static void main(String[] args) {
final TestClass testClass = Mockito.spy(new TestClass());
Mockito.when(testClass.getThing()).thenReturn("Some Other thing");
System.out.println(testClass.getOtherThing());
}
Output is:
Some Other thing
NB: You should really try to mock the dependencies for the class being tested not the class itself.
If the first item is to be used as a placeholder (empty value) and your select is required
then you can use the :invalid
pseudo-class to target it.
select {_x000D_
-webkit-appearance: menulist-button;_x000D_
color: black;_x000D_
}_x000D_
_x000D_
select:invalid {_x000D_
color: green;_x000D_
}
_x000D_
<select required>_x000D_
<option value="">Item1</option>_x000D_
<option value="Item2">Item2</option>_x000D_
<option value="Item3">Item3</option>_x000D_
</select>
_x000D_
Here is a complete test case that simulates the click
event, calls all handlers attached (however they have been attached), maintains the "target"
attribute ("srcElement"
in IE), bubbles like a normal event would, and emulates IE's recursion-prevention. Tested in FF 2, Chrome 2.0, Opera 9.10 and of course IE (6):
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script>
function fakeClick(event, anchorObj) {
if (anchorObj.click) {
anchorObj.click()
} else if(document.createEvent) {
if(event.target !== anchorObj) {
var evt = document.createEvent("MouseEvents");
evt.initMouseEvent("click", true, true, window,
0, 0, 0, 0, 0, false, false, false, false, 0, null);
var allowDefault = anchorObj.dispatchEvent(evt);
// you can check allowDefault for false to see if
// any handler called evt.preventDefault().
// Firefox will *not* redirect to anchorObj.href
// for you. However every other browser will.
}
}
}
</script>
</head>

<div onclick="alert('Container clicked')">
<a id="link" href="#" onclick="alert((event.target || event.srcElement).innerHTML)">Normal link</a>

It avoids recursion in non-IE browsers by inspecting the event object that is initiating the simulated click, by inspecting the target
attribute of the event (which remains unchanged during propagation).
Obviously IE does this internally holding a reference to its global event
object. DOM level 2 defines no such global variable, so for that reason the simulator must pass in its local copy of event
.
I'm assuming you're talking about com.google.common.base.Predicate<T>
from Guava.
From the API:
Determines a
true
orfalse
value for a given input. For example, aRegexPredicate
might implementPredicate<String>
, and return true for any string that matches its given regular expression.
This is essentially an OOP abstraction for a boolean
test.
For example, you may have a helper method like this:
static boolean isEven(int num) {
return (num % 2) == 0; // simple
}
Now, given a List<Integer>
, you can process only the even numbers like this:
List<Integer> numbers = Arrays.asList(1,2,3,4,5,6,7,8,9,10);
for (int number : numbers) {
if (isEven(number)) {
process(number);
}
}
With Predicate
, the if
test is abstracted out as a type. This allows it to interoperate with the rest of the API, such as Iterables
, which have many utility methods that takes Predicate
.
Thus, you can now write something like this:
Predicate<Integer> isEven = new Predicate<Integer>() {
@Override public boolean apply(Integer number) {
return (number % 2) == 0;
}
};
Iterable<Integer> evenNumbers = Iterables.filter(numbers, isEven);
for (int number : evenNumbers) {
process(number);
}
Note that now the for-each loop is much simpler without the if
test. We've reached a higher level of abtraction by defining Iterable<Integer> evenNumbers
, by filter
-ing using a Predicate
.
Iterables.filter
Predicate
allows Iterables.filter
to serve as what is called a higher-order function. On its own, this offers many advantages. Take the List<Integer> numbers
example above. Suppose we want to test if all numbers are positive. We can write something like this:
static boolean isAllPositive(Iterable<Integer> numbers) {
for (Integer number : numbers) {
if (number < 0) {
return false;
}
}
return true;
}
//...
if (isAllPositive(numbers)) {
System.out.println("Yep!");
}
With a Predicate
, and interoperating with the rest of the libraries, we can instead write this:
Predicate<Integer> isPositive = new Predicate<Integer>() {
@Override public boolean apply(Integer number) {
return number > 0;
}
};
//...
if (Iterables.all(numbers, isPositive)) {
System.out.println("Yep!");
}
Hopefully you can now see the value in higher abstractions for routines like "filter all elements by the given predicate", "check if all elements satisfy the given predicate", etc make for better code.
Unfortunately Java doesn't have first-class methods: you can't pass methods around to Iterables.filter
and Iterables.all
. You can, of course, pass around objects in Java. Thus, the Predicate
type is defined, and you pass objects implementing this interface instead.
Basically, if you are developing a client- server application. You may use WCF -> in order to make connection between client and server, WPF -> as client side to present the data.
You can also prepend your command with env
to inject Environment variables like so:
0 * * * * env VARIABLE=VALUE /usr/bin/mycommand
Heres an easy option. Just set your list option then set its text as selected value:
$("#ddlScheduleFrequency option").selected(text("Select One..."));
Why not use @media-queries? These are designed for that exact purpose. You can also do this with jQuery, but that's a last resort in my book.
var s = document.createElement("script");
//Check if viewport is smaller than 768 pixels
if(window.innerWidth < 768) {
s.type = "text/javascript";
s.src = "http://www.example.com/public/assets/css1";
}else { //Else we have a larger screen
s.type = "text/javascript";
s.src = "http://www.example.com/public/assets/css2";
}
$(function(){
$("head").append(s); //Inject stylesheet
})
I created a script to ignore differences in line endings:
It will display the files which are not added to the commit list and were modified (after ignoring differences in line endings). You can add the argument "add" to add those files to your commit.
#!/usr/bin/perl
# Usage: ./gitdiff.pl [add]
# add : add modified files to git
use warnings;
use strict;
my ($auto_add) = @ARGV;
if(!defined $auto_add) {
$auto_add = "";
}
my @mods = `git status --porcelain 2>/dev/null | grep '^ M ' | cut -c4-`;
chomp(@mods);
for my $mod (@mods) {
my $diff = `git diff -b $mod 2>/dev/null`;
if($diff) {
print $mod."\n";
if($auto_add eq "add") {
`git add $mod 2>/dev/null`;
}
}
}

As pointed by Larcho, starting from API level 10, you can use BitmapRegionDecoder
to load specific regions from an image and with that, you can accomplish to show a large image in high resolution by allocating in memory just the needed regions. I've recently developed a lib that provides the visualisation of large images with touch gesture handling. The source code and samples are available here.
One thing to keep in mind is that the relevant path here is the path relative to the file system location of your class... in your case TestGameTable.class. It is not related to the location of the TestGameTable.java file.
I left a more detailed answer here... where is resource actually located
Use a loop
for(var i = 0; i < obj.length; ++i){
//do something with obj[i]
for(var ind in obj[i]) {
console.log(ind);
for(var vals in obj[i][ind]){
console.log(vals, obj[i][ind][vals]);
}
}
}
Scope defines the area, where functions, variables and such are available. The availability of a variable for example is defined within its the context, let's say the function, file, or object, they are defined in. We usually call these local variables.
The lexical part means that you can derive the scope from reading the source code.
Lexical scope is also known as static scope.
Dynamic scope defines global variables that can be called or referenced from anywhere after being defined. Sometimes they are called global variables, even though global variables in most programmin languages are of lexical scope. This means, it can be derived from reading the code that the variable is available in this context. Maybe one has to follow a uses or includes clause to find the instatiation or definition, but the code/compiler knows about the variable in this place.
In dynamic scoping, by contrast, you search in the local function first, then you search in the function that called the local function, then you search in the function that called that function, and so on, up the call stack. "Dynamic" refers to change, in that the call stack can be different every time a given function is called, and so the function might hit different variables depending on where it is called from. (see here)
To see an interesting example for dynamic scope see here.
For further details see here and here.
Some examples in Delphi/Object Pascal
Delphi has lexical scope.
unit Main;
uses aUnit; // makes available all variables in interface section of aUnit
interface
var aGlobal: string; // global in the scope of all units that use Main;
type
TmyClass = class
strict private aPrivateVar: Integer; // only known by objects of this class type
// lexical: within class definition,
// reserved word private
public aPublicVar: double; // known to everyboday that has access to a
// object of this class type
end;
implementation
var aLocalGlobal: string; // known to all functions following
// the definition in this unit
end.
The closest Delphi gets to dynamic scope is the RegisterClass()/GetClass() function pair. For its use see here.
Let's say that the time RegisterClass([TmyClass]) is called to register a certain class cannot be predicted by reading the code (it gets called in a button click method called by the user), code calling GetClass('TmyClass') will get a result or not. The call to RegisterClass() does not have to be in the lexical scope of the unit using GetClass();
Another possibility for dynamic scope are anonymous methods (closures) in Delphi 2009, as they know the variables of their calling function. It does not follow the calling path from there recursively and therefore is not fully dynamic.
I'd like to share that Ansible can be run on localhost via shell:
ansible all -i "localhost," -c local -m shell -a 'echo hello world'
This could be helpful for simple tasks or for some hands-on learning of Ansible.
The example of code is taken from this good article:
From your comments, it seems like you're looking for "best practices" for the use of the Boolean
wrapper class. But there really aren't any best practices, because it's a bad idea to use this class to begin with. The only reason to use the object wrapper is in cases where you absolutely must (such as when using Generics, i.e., storing a boolean
in a HashMap<String, Boolean>
or the like). Using the object wrapper has no upsides and a lot of downsides, most notably that it opens you up to NullPointerException
s.
Does it matter if '!' is used instead of .equals() for Boolean?
Both techniques will be susceptible to a NullPointerException
, so it doesn't matter in that regard. In the first scenario, the Boolean
will be unboxed into its respective boolean
value and compared as normal. In the second scenario, you are invoking a method from the Boolean
class, which is the following:
public boolean equals(Object obj) {
if (obj instanceof Boolean) {
return value == ((Boolean)obj).booleanValue();
}
return false;
}
Either way, the results are the same.
Would it matter if .equals(false) was used to check for the value of the Boolean checker?
Per above, no.
Secondary question: Should Boolean be dealt differently than boolean?
If you absolutely must use the Boolean
class, always check for null
before performing any comparisons. e.g.,
Map<String, Boolean> map = new HashMap<String, Boolean>();
//...stuff to populate the Map
Boolean value = map.get("someKey");
if(value != null && value) {
//do stuff
}
This will work because Java short-circuits conditional evaluations. You can also use the ternary operator.
boolean easyToUseValue = value != null ? value : false;
But seriously... just use the primitive type, unless you're forced not to.
There aren't a lot of "Best Practices" yet. Those of us that are using inline-styles, for React components, are still very much experimenting.
There are a number of approaches that vary wildly: React inline-style lib comparison chart
What we refer to as "style" actually includes quite a few concepts:
React is already managing the state of your components, this makes styles of state and behavior a natural fit for colocation with your component logic.
Instead of building components to render with conditional state-classes, consider adding state-styles directly:
// Typical component with state-classes
<li
className={classnames({ 'todo-list__item': true, 'is-complete': item.complete })} />
// Using inline-styles for state
<li className='todo-list__item'
style={(item.complete) ? styles.complete : {}} />
Note that we're using a class to style appearance but no longer using any .is-
prefixed class for state and behavior.
We can use Object.assign
(ES6) or _.extend
(underscore/lodash) to add support for multiple states:
// Supporting multiple-states with inline-styles
<li 'todo-list__item'
style={Object.assign({}, item.complete && styles.complete, item.due && styles.due )}>
Now that we're using Object.assign
it becomes very simple to make our component reusable with different styles. If we want to override the default styles, we can do so at the call-site with props, like so: <TodoItem dueStyle={ fontWeight: "bold" } />
. Implemented like this:
<li 'todo-list__item'
style={Object.assign({},
item.due && styles.due,
item.due && this.props.dueStyles)}>
Personally, I don't see compelling reason to inline layout styles. There are a number of great CSS layout systems out there. I'd just use one.
That said, don't add layout styles directly to your component. Wrap your components with layout components. Here's an example.
// This couples your component to the layout system
// It reduces the reusability of your component
<UserBadge
className="col-xs-12 col-sm-6 col-md-8"
firstName="Michael"
lastName="Chan" />
// This is much easier to maintain and change
<div class="col-xs-12 col-sm-6 col-md-8">
<UserBadge
firstName="Michael"
lastName="Chan" />
</div>
For layout support, I often try to design components to be 100%
width
and height
.
This is the most contentious area of the "inline-style" debate. Ultimately, it's up to the component your designing and the comfort of your team with JavaScript.
One thing is certain, you'll need the assistance of a library. Browser-states (:hover
, :focus
), and media-queries are painful in raw React.
I like Radium because the syntax for those hard parts is designed to model that of SASS.
Often you'll see a style object outside of the module. For a todo-list component, it might look something like this:
var styles = {
root: {
display: "block"
},
item: {
color: "black"
complete: {
textDecoration: "line-through"
},
due: {
color: "red"
}
},
}
Adding a bunch of style logic to your template can get a little messy (as seen above). I like to create getter functions to compute styles:
React.createClass({
getStyles: function () {
return Object.assign(
{},
item.props.complete && styles.complete,
item.props.due && styles.due,
item.props.due && this.props.dueStyles
);
},
render: function () {
return <li style={this.getStyles()}>{this.props.item}</li>
}
});
I discussed all of these in more detail at React Europe earlier this year: Inline Styles and when it's best to 'just use CSS'.
I'm happy to help as you make new discoveries along the way :) Hit me up -> @chantastic
A reasonable thing you can do is to convert the list into a dict and then access it with the get method:
>>> my_list = ['a', 'b', 'c', 'd', 'e']
>>> my_dict = dict(enumerate(my_list))
>>> print my_dict
{0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e'}
>>> my_dict.get(2)
'c'
>>> my_dict.get(10, 'N/A')

Can you assign a unique CSS class to each distinct timer? That way you could use the selector for the CSS class, which would work fine with multiple div
elements.
I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).
Read my answer there for a fuller explaination, but in short:
They removed it deliberately, because compat mode is not actually really very good for testing compatibility.
If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.
The only way to get compat mode in IE11 is to set the X-UA-Compatible
header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.
It is not possible to redirect a POST somewhere else. When you have POSTED the request, the browser will get a response from the server and then the POST is done. Everything after that is a new request. When you specify a location header in there the browser will always use the GET method to fetch the next page.
You could use some Ajax to submit the form in background. That way your form values stay intact. If the server accepts, you can still redirect to some other page. If the server does not accept, then you can display an error message, let the user correct the input and send it again.

int width = Math.round((float) ratio * realImage.getWidth());

Why not have a hidden anchor tag on the page with the target set as you need, then simulate clicking it when you need the pop out?
How can I simulate a click to an anchor tag?
This would work in the cases where the window.open did not work
I use a few methods depending. In the same stylesheet i use: @media (max-width: 450px), or for separate make sure you have the link in the header correctly. I had a look at your fixmeup and you have a confusing array of links to css. It acts as you say also on HTC desire S.
Fragments can be added inside other fragments but then you will need to remove it from parent Fragment each time when onDestroyView()
method of parent fragment is called. And again add it in Parent Fragment's onCreateView()
method.
Just do like this :
@Override
public void onDestroyView()
{
FragmentManager mFragmentMgr= getFragmentManager();
FragmentTransaction mTransaction = mFragmentMgr.beginTransaction();
Fragment childFragment =mFragmentMgr.findFragmentByTag("qa_fragment")
mTransaction.remove(childFragment);
mTransaction.commit();
super.onDestroyView();
}
EDIT: This answer might be outdated if you're using a recent version of jQueryUI.

Here's the script -

return false;
});
$("#targetDiv").dialog({ //create dialog, but keep it closed
autoOpen: false,
height: 300,
width: 350,
modal: true
});
function showDialog(url){ //load content and open dialog
$("#targetDiv").load(url);

A view uses a query to pull data from the underlying tables.
A materialized view is a table on disk that contains the result set of a query.
Materialized views are primarily used to increase application performance when it isn't feasible or desirable to use a standard view with indexes applied to it. Materialized views can be updated on a regular basis either through triggers or by using the ON COMMIT REFRESH
option. This does require a few extra permissions, but it's nothing complex. ON COMMIT REFRESH
has been in place since at least Oracle 10.

Maybe this would help:
String[] some_array = getResources().getStringArray(R.array.your_string_array)
So you get the array-list as a String[] and then choose any i, some_array[i].
It may help to use a different constructor for Uri.
If you have the server name
string server = "http://www.myserver.com";
and have a relative Uri path to append to it, e.g.
string relativePath = "sites/files/images/picture.png"
When creating a Uri from these two I get the "format could not be determined" exception unless I use the constructor with the UriKind argument, i.e.
// this works, because the protocol is included in the string
Uri serverUri = new Uri(server);
// needs UriKind arg, or UriFormatException is thrown
Uri relativeUri = new Uri(relativePath, UriKind.Relative);
// Uri(Uri, Uri) is the preferred constructor in this case
Uri fullUri = new Uri(serverUri, relativeUri);

For SQL Management studio I used a variation of BWS' answer. This gets the data to the right of '=', or NULL if the symbol doesn't exist:

I recently published a project that allows PHP to obtain and interact with a real Bash shell. Get it here: https://github.com/merlinthemagic/MTS The shell has a pty (pseudo terminal device, same as you would have in i.e. a ssh session), and you can get the shell as root if desired. Not sure you need root to execute your script, but given you mention sudo it is likely.
After downloading you would simply use the following code:
$shell = \MTS\Factories::getDevices()->getLocalHost()->getShell('bash', true);
$return1 = $shell->exeCmd('/path/to/osascript myscript.scpt');
I struggled with this for a while; a particularly frustrating website had several nested frames throughout the site. I couldn't find any way to identify the frames- no name, id, xpath, css selector- nothing.
Eventually I realised that frames are numbered with the top level being frame(0) the second frame(1) etc.
As I still didn't know which frame the element I needed was sitting in, I wrote a for loop to start from 0 and cycle to 50 continually moving to the next frame and attempting to access my required element; if it failed I got it to print a message and continue.
Spent too much time on this problem for such a simple solution -_-
driver.switch_to.default_content()
for x in range(50):
try:
driver.switch_to.frame(x)
driver.find_element_by_xpath("//*[@id='23']").click()
driver.find_element_by_xpath("/html/body/form/table/tbody/tr[1]/td/ul/li[49]/a").click()
except:
print("It's not: ", x)
continue
I'm not sure for JPA 1.0 but you can pass a Collection
in JPA 2.0:
String qlString = "select item from Item item where item.name IN :names";
Query q = em.createQuery(qlString, Item.class);
List<String> names = Arrays.asList("foo", "bar");
q.setParameter("names", names);
List<Item> actual = q.getResultList();
assertNotNull(actual);
assertEquals(2, actual.size());
Tested with EclipseLInk. With Hibernate 3.5.1, you'll need to surround the parameter with parenthesis:
String qlString = "select item from Item item where item.name IN (:names)";
But this is a bug, the JPQL query in the previous sample is valid JPQL. See HHH-5126.
What you need is:
if (!File.Exists(@"c:\test\Test\SomeFile.txt")) {
File.Move(@"c:\test\SomeFile.txt", @"c:\test\Test\SomeFile.txt");
}
or
if (File.Exists(@"c:\test\Test\SomeFile.txt")) {
File.Delete(@"c:\test\Test\SomeFile.txt");
}
File.Move(@"c:\test\SomeFile.txt", @"c:\test\Test\SomeFile.txt");
This will either:
Edit: I should clarify my answer, even though it's the most upvoted!
The second parameter of File.Move should be the destination file - not a folder. You are specifying the second parameter as the destination folder, not the destination filename - which is what File.Move requires.
So, your second parameter should be c:\test\Test\SomeFile.txt
.
I prefer to use GIT_ASKPASS environment for providing HTTPS credentials to git.

It happens when you have a file with the same name as Makefile target name in the directory where the Makefile is present.
If you are on Windows, you can use the CreateThreadpoolTimer function to schedule a callback without needing to worry about thread management and without blocking the current thread.
template<typename T>
static void __stdcall timer_fired(PTP_CALLBACK_INSTANCE, PVOID context, PTP_TIMER timer)
{
CloseThreadpoolTimer(timer);
std::unique_ptr<T> callable(reinterpret_cast<T*>(context));
(*callable)();
}
template <typename T>
void call_after(T callable, long long delayInMs)
{
auto state = std::make_unique<T>(std::move(callable));
auto timer = CreateThreadpoolTimer(timer_fired<T>, state.get(), nullptr);
if (!timer)
{
throw std::runtime_error("Timer");
}
ULARGE_INTEGER due;
due.QuadPart = static_cast<ULONGLONG>(-(delayInMs * 10000LL));
FILETIME ft;
ft.dwHighDateTime = due.HighPart;
ft.dwLowDateTime = due.LowPart;
SetThreadpoolTimer(timer, &ft, 0 /*msPeriod*/, 0 /*msWindowLength*/);
state.release();
}
int main()
{
auto callback = []
{
std::cout << "in callback\n";
};
call_after(callback, 1000);
std::cin.get();
}
Answering late since I recently had the same question when reading text from file; tried several options such as:
with open('verdict.txt') as f:
First option below produces a list called alist
, with '\n'
stripped, then joins back into full text (optional if you wish to have only one text):
alist = f.read().splitlines()
jalist = " ".join(alist)
Second option below is much easier and simple produces string of text called atext
replacing '\n'
with space;
atext = f.read().replace('\n',' ')
It works; I have done it. This is clean, easier, and efficient.
I prefer just going into less
and
:43210
to do the same and stuff like that.
Even better: hit v to start editing (in vim, of course!), at that location. Now, note that vim
has the same key bindings!
I like this approach, it is visual for me.
using (var webClient = new WebClient())
{
var response = webClient.DownloadString(url);
JObject result = JObject.Parse(response);
var users = result.SelectToken("data");
List<User> userList = JsonConvert.DeserializeObject<List<User>>(users.ToString());
}
VB6:
Listview1.selecteditem
VB10:
Listview1.FocusedItem.Text

This works in python 2 and 3 and is a bit cleaner than before, but requires SA>=1.0.

There is a chance...
You might be missing @Service
, @Repository
annotation on your respective implementation classes.
The Easiest way example to show you how to do that is :
Code :
>>> points = 19.5
>>> total = 22
>>>'Correct answers: {:.2%}'.format(points/total)
`
Output : Correct answers: 88.64%
In the example that you have provided there is nothing that would throw a SQL command not properly formed
error. How are you executing this query? What are you not showing us?
This example script works fine:
create table tableName
(session_start_date_time DATE);
insert into tableName (session_start_date_time)
values (sysdate+1);
select * from tableName
where session_start_date_time > to_date('12-Jan-2012 16:00', 'DD-MON-YYYY hh24:mi');
As does this example:
create table tableName2
(session_start_date_time TIMESTAMP);
insert into tableName2 (session_start_date_time)
values (to_timestamp('01/12/2012 16:01:02.345678','mm/dd/yyyy hh24:mi:ss.ff'));
select * from tableName2
where session_start_date_time > to_date('12-Jan-2012 16:00', 'DD-MON-YYYY hh24:mi');
select * from tableName2
where session_start_date_time > to_timestamp('01/12/2012 14:01:02.345678','mm/dd/yyyy hh24:mi:ss.ff');
So there must be something else that is wrong.
I tried this:
long now = System.currentTimeMillis();
for (int i = 0; i < 10000000; i++) {
new Date().getTime();
}
long result = System.currentTimeMillis() - now;
System.out.println("Date(): " + result);
now = System.currentTimeMillis();
for (int i = 0; i < 10000000; i++) {
System.currentTimeMillis();
}
result = System.currentTimeMillis() - now;
System.out.println("currentTimeMillis(): " + result);
And result was:
Date(): 199
currentTimeMillis(): 3
I was facing the same issue for one of my phonegap project. To resolve this I have followed , following step
1) Right click on Project name (In my Case android) , select "Open Module Settings"
2) Select modules (android and CordovaLib)
3) Click properties on top
4) Chose Compile SDK version (I have chosen API 26: Android 8.0 )
5) Choose Build Tools Version (I have chosen 26.0.2)
6) Source Compatibility ( 1.6)
7) Target Compatibility ( 1.6)
Click Ok and rebuild project.
Also one more additional step
Add
compile 'com.android.support:appcompat-v7:27.0.2'
build.gradle (Module:android)
Following link shows my setting for step I have followed
Herb Sutter is still on record, along with Bjarne Stroustroup, in recommending const std::string&
as a parameter type; see https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#Rf-in .
There is a pitfall not mentioned in any of the other answers here: if you pass a string literal to a const std::string&
parameter, it will pass a reference to a temporary string, created on-the-fly to hold the characters of the literal. If you then save that reference, it will be invalid once the temporary string is deallocated. To be safe, you must save a copy, not the reference. The problem stems from the fact that string literals are const char[N]
types, requiring promotion to std::string
.
The code below illustrates the pitfall and the workaround, along with a minor efficiency option -- overloading with a const char*
method, as described at Is there a way to pass a string literal as reference in C++.
(Note: Sutter & Stroustroup advise that if you keep a copy of the string, also provide an overloaded function with a && parameter and std::move() it.)
#include <string>
#include <iostream>
class WidgetBadRef {
public:
WidgetBadRef(const std::string& s) : myStrRef(s) // copy the reference...
{}
const std::string& myStrRef; // might be a reference to a temporary (oops!)
};
class WidgetSafeCopy {
public:
WidgetSafeCopy(const std::string& s) : myStrCopy(s)
// constructor for string references; copy the string
{std::cout << "const std::string& constructor\n";}
WidgetSafeCopy(const char* cs) : myStrCopy(cs)
// constructor for string literals (and char arrays);
// for minor efficiency only;
// create the std::string directly from the chars
{std::cout << "const char * constructor\n";}
const std::string myStrCopy; // save a copy, not a reference!
};
int main() {
WidgetBadRef w1("First string");
WidgetSafeCopy w2("Second string"); // uses the const char* constructor, no temp string
WidgetSafeCopy w3(w2.myStrCopy); // uses the String reference constructor
std::cout << w1.myStrRef << "\n"; // garbage out
std::cout << w2.myStrCopy << "\n"; // OK
std::cout << w3.myStrCopy << "\n"; // OK
}
OUTPUT:
const char * constructor const std::string& constructor Second string Second string
If your HP-UX installation has Tcl installed, you might find it's date arithmetic very readable (unfortunately the Tcl shell does not have a nice "-e" option like perl):
dt=$(echo 'puts [clock format [clock scan yesterday] -format "%a %d/%m/%Y"]' | tclsh)
echo "yesterday was $dt"
This will handle all the daylight savings bother.
Consider the second script. If you import it in another one, the instructions, as at "global level", will be executed.
You can fake the disabled effect using CSS.
pointer-events:none;
You might also want to change colors etc.
Test e = static_cast<Test>(1);
You can use the toolchain file mechanism of cmake for this purpose, see e.g. here. You write a toolchain file for each compiler containing the corresponding definitions. At config time, you run e.g
cmake -DCMAKE_TOOLCHAIN_FILE=/path/to/clang-toolchain.cmake ..
and all the compiler information will be set during the project() call from the toolchain file. Though in the documentation is mentionend only in the context of cross-compiling, it works as well for different compilers on the same system.
After creating the new image, are you removing the old image from the DOM and replacing it with the new one?
You could be grabbing new images every updateImage call, but not adding them to the page.
There are a number of ways to do it. Something like this would work.
function updateImage()
{
var image = document.getElementById("theText");
if(image.complete) {
var new_image = new Image();
//set up the new image
new_image.id = "theText";
new_image.src = image.src;
// insert new image and remove old
image.parentNode.insertBefore(new_image,image);
image.parentNode.removeChild(image);
}
setTimeout(updateImage, 1000);
}
After getting that working, if there are still problems it is probably a caching issue like the other answers talk about.
To switch between color schemes: Choose View -> Quick Switch Scheme on the main menu or press Ctrl+Back Quote To bring back the old theme: Settings -> Appearance -> Theme
your 8080 port is already used by another application 1/ you can try to find out which app is using it, using "netstat -aon" and stop the process; 2/ you can go to server.xml and change from port 8080 to another one (ex: 8081)
I got same problem. So I looked into the axios document. I found it. you can do it like this. this is easiest way. and super simple.
https://www.npmjs.com/package/axios#using-applicationx-www-form-urlencoded-format
var params = new URLSearchParams();
params.append('param1', 'value1');
params.append('param2', 'value2');
axios.post('/foo', params);
You can use .then,.catch.
Here is an example:
public class TextViewMarquee extends Activity {
private TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv = (TextView) this.findViewById(R.id.mywidget);
tv.setSelected(true); // Set focus to the textview
}
}
The xml file with the textview:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="@+id/mywidget"

The easiest way would probably be to put your web resources into the assets folder then call:
webView.loadUrl("file:///android_asset/filename.html");
For Complete Communication between Java and Webview See This
Update: The assets folder is usually the following folder:
<project>/src/main/assets
This can be changed in the asset folder configuration setting in your <app>.iml
file as:
<option name=”ASSETS_FOLDER_RELATIVE_PATH” value=”/src/main/assets” />
See Article Where to place the assets folder in Android Studio
Use Character.isWhitespace() rather than creating your own.
In Java how does one turn a String into a char or a char into a String?
You can use:
<asp:textbox id="textBox1" style="text-align:center"></asp:textbox>
Or this:
textbox.Style["text-align"] = "center"; //right, left

If you happened to know the general location of cell towers, you could check to see if the current cell tower matches the location given (within an error margin of something large, like 10 or more miles).
For example, if your app unlocks features only if the user is in a specific location (your store, for example), you could check gps as well as cell towers. Currently, no gps spoofing app also spoofs the cell towers, so you could see if someone across the country is simply trying to spoof their way into your special features (I'm thinking of the Disney Mobile Magic app, for one example).
This is how the Llama app manages location by default, since checking cell tower ids are much less battery intensive than gps. It isn't useful for very specific locations, but if home and work are several miles away, it can distinguish between the two general locations very easily.
Of course, this would require the user to have a cell signal at all. And you would have to know all the cell towers ids in the area --on all network providers-- or you would run the risk of a false negative.
If your div looks like this:
<div id="MyDiv">content in here</div>
Then this Javascript:
document.getElementById("MyDiv").innerHTML = "";
will make it look like this:
<div id="MyDiv"></div>
For Jackson to serialize that class, the SomeString
field needs to either be public
(right now it's package level isolation) or you need to define getter and setter methods for it.
I'm not sure, what you mean as the 'mobile width'. But in each case, the CSS @media
can be used for hiding elements in the screen width basis. See some example:
<div id="my-content"></div>
...and:
@media screen and (min-width: 0px) and (max-width: 400px) {
#my-content { display: block; } /* show it on small screens */
}
@media screen and (min-width: 401px) and (max-width: 1024px) {
#my-content { display: none; } /* hide it elsewhere */
}
Some truly mobile detection is kind of hard programming and rather difficult. Eventually see the: http://detectmobilebrowsers.com/ or other similar sources.
Use findElement
instead of findElements
driver.findElement(By.xpath("//input[@id='invoice_supplier_id'])).sendKeys("your value");
OR
driver.findElement(By.id("invoice_supplier_id")).sendKeys("value", "your value");
OR using JavascriptExecutor
WebElement element = driver.findElement(By.xpath("enter the xpath here")); // you can use any locator
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("arguments[0].value='enter the value here';", element);
OR
(JavascriptExecutor) driver.executeScript("document.evaluate(xpathExpresion, document, null, 9, null).singleNodeValue.innerHTML="+ DesiredText);
OR (in javascript)
driver.findElement(By.xpath("//input[@id='invoice_supplier_id'])).setAttribute("value", "your value")
Hope it will help you :)
Yup, this is possible of course. Here are several examples.
-- one way to do this
DECLARE @Cnt int
SELECT @Cnt = COUNT(SomeColumn)
FROM TableName
GROUP BY SomeColumn
-- another way to do the same thing
DECLARE @StreetName nvarchar(100)

-- Assign values to several variables at once
DECLARE @val1 nvarchar(20)
DECLARE @val2 int
DECLARE @val3 datetime
DECLARE @val4 uniqueidentifier
DECLARE @val5 double
SELECT @val1 = TextColumn,
@val2 = IntColumn,
@val3 = DateColumn,
@val4 = GuidColumn,
@val5 = DoubleColumn
FROM SomeTable

don't cut it here. You need to use expand_limits
, scale_x_continuous
, and scale_y_continuous
. Try:
df <- data.frame(x = 1:5, y = 1:5)
p <- ggplot(df, aes(x, y)) + geom_point()
p <- p + expand_limits(x = 0, y = 0)
p # not what you are looking for
p + scale_x_continuous(expand = c(0, 0)) + scale_y_continuous(expand = c(0, 0))
You may need to adjust things a little to make sure points are not getting cut off (see, for example, the point at x = 5
and y = 5
.
One way to skip this is by creating a specific app password variable.
And you can use that generated password
to access or to push commits from your terminal, when using a Google Account to sign in into Bitbucket.
I wanted to remove the too-much spaces in a string (also in between the string, not only in the beginning or end). I made this, because I don't know how to do it otherwise:
string = "Name : David Account: 1234 Another thing: something "
ready = False
while ready == False:
pos = string.find(" ")
if pos != -1:
string = string.replace(" "," ")
else:
ready = True
print(string)
This replaces double spaces in one space until you have no double spaces any more

You are actually here touching two questions in one.
The first one is How to host your application?.
And as @toskv mentioned its really too broad question to be answered and depends on numerous different things.
The second one is How do you prepare the deployment version of the application?.
You have several options here:
Deploy using special bundling tools, like webpack
or systemjs
builder.
They come with all the possibilities that are lacking in #1.
You can pack all your app code into just a couple of js/css/... files that you reference in your HTML. systemjs
builder even allows you to get rid of the need to include systemjs
as part of your deployment package.
You can use ng deploy
as of Angular 8 to deploy your app from your CLI. ng deploy
will need to be used in conjunction with your platform of choice (such as @angular/fire
). You can check the official docs to see what works best for you here
Yes you will most likely need to deploy systemjs
and bunch of other external libraries as part of your package. And yes you will be able to bundle them into just couple of js files you reference from your HTML page.
You do not have to reference all your compiled js files from the page though - systemjs
as a module loader will take care of that.
I know it sounds muddy - to help get you started with the #2 here are two really good sample applications:
SystemJS builder: angular2 seed
WebPack: angular2 webpack starter
An alias will expand to the string it represents. Anything after the alias will appear after its expansion without needing to be or able to be passed as explicit arguments (e.g. $1
).
$ alias foo='/path/to/bar'
$ foo some args
will get expanded to
$ /path/to/bar some args
If you want to use explicit arguments, you'll need to use a function
$ foo () { /path/to/bar "$@" fixed args; }
$ foo abc 123
will be executed as if you had done
$ /path/to/bar abc 123 fixed args
To undefine an alias:
unalias foo
To undefine a function:
unset -f foo
To see the type and definition (for each defined alias, keyword, function, builtin or executable file):
type -a foo
Or type only (for the highest precedence occurrence):
type -t foo
This method takes one Function as an argument, this function accepts one parameter T as an input argument and return one stream of parameter R as a return value. When this function is applied on each element of this stream, it produces a stream of new values. All the elements of these new streams generated by each element are then copied to a new stream, which will be a return value of this method.

assert( (4 == numberlength<5000,10>::value) );
assert( (4 == numberlength<9999,10>::value) );
The second part of your question is answered well. Here is the answer for the first part: How to output multiple files with webpack:
entry: {
outputone: './source/fileone.jsx',
outputtwo: './source/filetwo.jsx'
},
output: {
path: path.resolve(__dirname, './wwwroot/js/dist'),
filename: '[name].js'
},
This will generate 2 files: outputone.js und outputtwo.js in the target folder.
I see that you've tagged this question with the google-spreadsheet-api
tag. So by "drop-down" do you mean Google App Script's ListBox? If so, you may toggle a user's ability to select multiple items from the ListBox with a simple true/false value.
Here's an example:
`var lb = app.createListBox(true).setId('myId').setName('myLbName');`
Notice that multiselect is enabled because of the word true.
When modal appears, it will trigger event show.bs.modal
before appearing. I tried at Safari 13.1.2
on MacOS 10.15.6
. When show.bs.modal
event triggered, the .modal-backgrop
is not inserted into body
yet.
So, I give up to addClass
, and removeClass
to .modal-backdrop
dynamically.
After viewing a lot articles on the Internet, I found a code snippet. It addClass
and removeClass
to the body
, which is the parent of .modal-backdrop
, when show.bs.modal
and hide.bs.modal
events triggered.
ps: I use Bootstrap 4.5.
// In order to addClass/removeClass on the `body`. The parent of `.modal-backdrop`
.no-modal-bg .modal-backdrop {
background: none;
}
$('#myModalId').on('show.bs.modal', function(e) {
$('body').addClass('no-modal-bg');
}).on('hidden.bs.modal', function(e) {
// 'hide.bs.modal' or 'hidden.bs.modal', depends on your needs.
$('body').removeClass('no-modal-bg');

This error happen usually when tables in the query doesn't exist. Just check the table's spelling in the query, and it will work.
In SSMS, "Query" menu item... "Results to"... "Results to File"
Shortcut = CTRL+shift+F
You can set it globally too
"Tools"... "Options"... "Query Results"... "SQL Server".. "Default destination" drop down
Edit: after comment
In SSMS, "Query" menu item... "SQLCMD" mode
This allows you to run "command line" like actions.

Android SharedPreferances allow you to save primitive types (Boolean, Float, Int, Long, String and StringSet which available since API11) in memory as an xml file.
The key idea of any solution would be to convert the data to one of those primitive types.
I personally love to convert the my list to json format and then save it as a String in a SharedPreferences value.
In order to use my solution you'll have to add Google Gson lib.
In gradle just add the following dependency (please use google's latest version):
compile 'com.google.code.gson:gson:2.6.2'
Save data (where HttpParam is your object):
List<HttpParam> httpParamList = "**get your list**"
String httpParamJSONList = new Gson().toJson(httpParamList);
SharedPreferences prefs = getSharedPreferences(**"your_prefes_key"**, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
editor.putString(**"your_prefes_key"**, httpParamJSONList);
editor.apply();
Retrieve Data (where HttpParam is your object):
SharedPreferences prefs = getSharedPreferences(**"your_prefes_key"**, Context.MODE_PRIVATE);
String httpParamJSONList = prefs.getString(**"your_prefes_key"**, "");
List<HttpParam> httpParamList =
new Gson().fromJson(httpParamJSONList, new TypeToken<List<HttpParam>>() {
}.getType());
If you have assigned a certain controller to your view, then your controller will be invoked every time your view loads. In that case, you can execute some code in your controller as soon as it is invoked, for example this way:
<ion-nav-view ng-controller="indexController" name="other" ng-init="doSomething()"></ion-nav-view>
And in your controller:
app.controller('indexController', function($scope) {
/*
Write some code directly over here without any function,
and it will be executed every time your view loads.
Something like this:
*/
$scope.xyz = 1;
});
Edit: You might try to track state changes and then execute some code when the route is changed and a certain route is visited, for example:
$rootScope.$on('$stateChangeSuccess',
function(event, toState, toParams, fromState, fromParams){ ... })
You can find more details here: State Change Events.
Along the lines of the HTTP Proxy answers, this can also happen due to a VPN connection. Disconnecting my VPN connection solved it for me.
like this:
/\<word\>
\<
means beginning of a word, and \>
means the end of a word,
Adding @Roe's comment:
VIM provides a shortcut for this. If you already have word on screen and you want to find other instances of it, you can put the cursor on the word and press '*'
to search forward in the file or '#'
to search backwards.
There is the option Microsoft Software Licensing and Protection (SLP) Services as well. After reading about it I really wish I could use it.
I really like the idea of blocking parts of code based on the license. Hot stuff, and the most secure for .NET. Interesting read even if you don't use it!
Microsoft® Software Licensing and Protection (SLP) Services is a software activation service that enables independent software vendors (ISVs) to adopt flexible licensing terms for their customers. Microsoft SLP Services employs a unique protection method that helps safeguard your application and licensing information allowing you to get to market faster while increasing customer compliance.
Note: This is the only way I would release a product with sensitive code (such as a valuable algorithm).
Inside file strings.xml
define a String resource like this:
<string name="string_to_format">Amount: %1$f for %2$d days%3$s</string>
Inside your code (assume it inherits from Context) simply do the following:
String formattedString = getString(R.string.string_to_format, floatVar, decimalVar, stringVar);
(In comparison to the answer from LocalPCGuy or Giovanny Farto M. the String.format method is not needed.)
The easiest way is to call onCreate(null);
and your activity will be like new.
On unixoid systems (and in php 7+ on Windows as well), you can use getrusage, like:
// Script start
$rustart = getrusage();
// Code ...
// Script end
function rutime($ru, $rus, $index) {
return ($ru["ru_$index.tv_sec"]*1000 + intval($ru["ru_$index.tv_usec"]/1000))
- ($rus["ru_$index.tv_sec"]*1000 + intval($rus["ru_$index.tv_usec"]/1000));
}
$ru = getrusage();
echo "This process used " . rutime($ru, $rustart, "utime") .
" ms for its computations\n";
echo "It spent " . rutime($ru, $rustart, "stime") .
" ms in system calls\n";
Note that you don't need to calculate a difference if you are spawning a php instance for every test.

In your Manifest file write this before </application >

Even i was facing the same problem ,but solved it by
conda install -c conda-forge pysoundfile
while importing it
import soundfile
use...
# chmod 400 ec2-keypair.pem
don't use the 600 permission otherwise you might overwrite your key accidently.
As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.
Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash
is incorrect and should have been callbackOnLocationHash
(note the mis-spelling of "Location").
This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.
Example:
interface TextOptions {
alignment?: string;
color?: string;
padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'
There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes
Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v
or v as T
) do not check for extra properties, so you can use them in place of a type annotation:
interface Options {
x?: string;
y?: number;
}
// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;
Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking
Before
interface Model {
name: string;
}
function createModel(x: Model) { ... }
// Error
createModel({name: 'hello', length: 100});
After
interface Model {
name: string;
[others: string]: any;
}
function createModel(x: Model) { ... }
// OK
createModel({name: 'hello', length: 100});
interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }
let x: Animal;
if(...) {
x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
x = { move: 'catwalk', meow: 'mrar' };
} else {
x = { move: 'gallop', neigh: 'wilbur' };
}
Two good solutions come to mind here
Specify a closed set for x
// Removes all errors
let x: Dog|Cat|Horse;
or Type assert each thing
// For each initialization
x = { move: 'doggy paddle', woof: 'bark' } as Dog;
A clean solution to the "data model" problem using intersection types:
interface DataModelOptions {
name?: string;
id?: number;
}
interface UserProperties {
[key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
/* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
/* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

What about -mmin
?
find /var/www/html/audio -daystart -maxdepth 1 -mmin +59 -type f -name "*.mp3" \
-exec rm -f {} \;
From man find:
-mmin n File's data was last modified n minutes ago.
Also, make sure to test this first!
... -exec echo rm -f '{}' \; ^^^^ Add the 'echo' so you just see the commands that are going to get run instead of actual trying them first.
The code creates an anonymous function, and then immediately runs it. Similar to:
var temp = function() {
// init part
}
temp();
The purpose of this construction is to create a scope for the code inside the function. You can declare varaibles and functions inside the scope, and those will be local to that scope. That way they don't clutter up the global scope, which minimizes the risk for conflicts with other scripts.
You need to specify an access modifier for your variable. In this case you want it public.
public class Variables
{
public static string name = "";
}
After this you can use the variable like this.
Variables.name
Try this one:
let uuid = NSUUID().uuidString
print(uuid)
Swift 3/4/5
let uuid = UUID().uuidString
print(uuid)
<html>
tag in Elements.<!DOCTYPE html>
before the <html>
.First off, you have to specify you wish to use Document Literal style:
$client = new SoapClient(NULL, array(
'location' => 'https://example.com/path/to/service',
'uri' => 'http://example.com/wsdl',
'trace' => 1,
'use' => SOAP_LITERAL)
);
Then, you need to transform your data into a SoapVar; I've written a simple transform function:
function soapify(array $data)
{
foreach ($data as &$value) {
if (is_array($value)) {
$value = soapify($value);
}
}
return new SoapVar($data, SOAP_ENC_OBJECT);
}
Then, you apply this transform function onto your data:
$data = soapify(array(
'Acquirer' => array(
'Id' => 'MyId',
'UserId' => 'MyUserId',
'Password' => 'MyPassword',
),
));
Finally, you call the service passing the Data parameter:
$method = 'Echo';
$result = $client->$method(new SoapParam($data, 'Data'));

If you strictly want to stick to using button,Then simply create an open window function as follows:
<script>
function myfunction() {
window.open("mynewpage.html");
}
</script>
Then in your html do the following with your button:
Join
So you would have something like this:
<body>
<script>
function joinfunction() {
window.open("mynewpage.html");
}
</script>
<button onclick="myfunction()" type="button" class="btn btn-default subs-btn">Join</button>
Below added code is working for me if you are using pattern dd-MM-yyyy.
public boolean isValidDate(String date) {
boolean check;
String date1 = "^(0?[1-9]|[12][0-9]|3[01])-(0?[1-9]|1[012])-([12][0-9]{3})$";
check = date.matches(date1);
return check;
}
The ServletContext#getRealPath()
is intented to convert a web content path (the path in the expanded WAR folder structure on the server's disk file system) to an absolute disk file system path.
The "/"
represents the web content root. I.e. it represents the web
folder as in the below project structure:
YourWebProject
|-- src
| :
|
|-- web
| |-- META-INF
| | `-- MANIFEST.MF
| |-- WEB-INF
| | `-- web.xml
| |-- index.jsp
| `-- login.jsp
:
So, passing the "/"
to getRealPath()
would return you the absolute disk file system path of the /web
folder of the expanded WAR file of the project. Something like /path/to/server/work/folder/some.war/
which you should be able to further use in File
or FileInputStream
.
Note that most starters don't seem to see/realize that you can actually pass the whole web content path to it and that they often use
String absolutePathToIndexJSP = servletContext.getRealPath("/") + "index.jsp"; // Wrong!
or even
String absolutePathToIndexJSP = servletContext.getRealPath("") + "index.jsp"; // Wronger!
instead of
String absolutePathToIndexJSP = servletContext.getRealPath("/index.jsp"); // Right!
Also note that even though you can write new files into it using FileOutputStream
, all changes (e.g. new files or edited files) will get lost whenever the WAR is redeployed; with the simple reason that all those changes are not contained in the original WAR file. So all starters who are attempting to save uploaded files in there are doing it wrong.
Moreover, getRealPath()
will always return null
or a completely unexpected path when the server isn't configured to expand the WAR file into the disk file system, but instead into e.g. memory as a virtual file system.
getRealPath()
is unportable; you'd better never use itUse getRealPath()
carefully. There are actually no sensible real world use cases for it. Based on my 20 years of Java EE experience, there has always been another way which is much better and more portable than getRealPath()
.
If all you actually need is to get an InputStream
of the web resource, better use ServletContext#getResourceAsStream()
instead, this will work regardless of the way how the WAR is expanded. So, if you for example want an InputStream
of index.jsp
, then do not do:
InputStream input = new FileInputStream(servletContext.getRealPath("/index.jsp")); // Wrong!
But instead do:
InputStream input = servletContext.getResourceAsStream("/index.jsp"); // Right!
Or if you intend to obtain a list of all available web resource paths, use ServletContext#getResourcePaths()
instead.
Set<String> resourcePaths = servletContext.getResourcePaths("/");
You can obtain an individual resource as URL
via ServletContext#getResource()
. This will return null
when the resource does not exist.
URL resource = servletContext.getResource(path);
Or if you intend to save an uploaded file, or create a temporary file, then see the below "See also" links.
If your system has systemctl
sudo systemctl reload nginx
If your system supports service
(using debian/ubuntu) try this
sudo service nginx reload
If not (using centos/fedora/etc) you can try the init script
sudo /etc/init.d/nginx reload
No, how you are doing it is correct.

JQuery .extend does this for you:
var mytsobject = new mytsobject();
var newObj = {a:1,b:2};
$.extend(mytsobject, newObj); //mytsobject will now contain a & b
You will want to use the a ternary operator which acts as a shortened IF/Else statement:
echo '<option value="'.$value.'" '.(($value=='United States')?'selected="selected"':"").'>'.$value.'</option>';
The following code tends to throw Style lint warnings:
@-moz-document url-prefix() {
h1 {
color: red;
}
}
Instead using
@-moz-document url-prefix('') {
h1 {
color: red;
}
}
Helped me out! Got the solution for style lint warning from here
There is no notion of method overloading in Python. But you can achieve a similar effect by specifying optional and keyword arguments
A small change to Paul's code so that it doesn't return the error mentioned above.
dat = melt(subset(iris, select = c("Sepal.Length","Sepal.Width", "Species")),
id.vars = "Species")
dat$x <- c(1:150, 1:150)
ggplot(aes(x = x, y = value, color = variable), data = dat) +
geom_point() + geom_line()
I think you need to define an object and then push in array
var obj = {};
obj[name] = val;
ary.push(obj);

Following @patrick-desjardins answer, I implemented abstract and it's implementation class along with @Test
as follows:
Abstract class - ABC.java
import java.util.ArrayList;
import java.util.List;
public abstract class ABC {
abstract String sayHello();
public List<String> getList() {
final List<String> defaultList = new ArrayList<>();
defaultList.add("abstract class");
return defaultList;
}
}
As Abstract classes cannot be instantiated, but they can be subclassed, concrete class DEF.java, is as follows:
public class DEF extends ABC {
@Override
public String sayHello() {
return "Hello!";
}
}
@Test class to test both abstract as well as non-abstract method:
import org.junit.Before;
import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.empty;
import static org.hamcrest.Matchers.is;
import static org.hamcrest.Matchers.not;
import static org.hamcrest.Matchers.contains;
import java.util.Collection;
import java.util.List;
import static org.hamcrest.Matchers.equalTo;
import org.junit.Test;
public class DEFTest {
private DEF def;
@Before
public void setup() {
def = new DEF();
}
@Test
public void add(){
String result = def.sayHello();
assertThat(result, is(equalTo("Hello!")));
}
@Test
public void getList(){
List<String> result = def.getList();
assertThat((Collection<String>) result, is(not(empty())));
assertThat(result, contains("abstract class"));
}
}
To set the data in kotlin
val offerIds = ArrayList<Offer>()
offerIds.add(Offer(1))
retrunIntent.putExtra(C.OFFER_IDS, offerIds)
To get the data
val offerIds = data.getSerializableExtra(C.OFFER_IDS) as ArrayList<Offer>?
Now access the arraylist
An assertion Error is thrown when say "You have written a code that should not execute at all costs because according to you logic it should not happen. BUT if it happens then throw AssertionError. And you don't catch it." In such a case you throw an Assertion error.
new IllegalStateException("Must not instantiate an element of this class")' // Is an Exception not error.
Note: Assertion Error comes under java.lang.Error And Errors not meant to be caught.
As mentioned in a comment (and another answer as I typed) you need to register an event handler to catch the keydown or keypress event on a text box. This is because TextChanged is only fired when the TextBox loses focus
The below regex lets you match those characters you want to allow
Regex regex = new Regex(@"[0-9+\-\/\*\(\)]");
MatchCollection matches = regex.Matches(textValue);
and this does the opposite and catches characters that aren't allowed
Regex regex = new Regex(@"[^0-9^+^\-^\/^\*^\(^\)]");
MatchCollection matches = regex.Matches(textValue);
I'm not assuming there'll be a single match as someone could paste text into the textbox. in which case catch textchanged
textBox1.TextChanged += new TextChangedEventHandler(textBox1_TextChanged);
private void textBox1_TextChanged(object sender, EventArgs e)
{
Regex regex = new Regex(@"[^0-9^+^\-^\/^\*^\(^\)]");
MatchCollection matches = regex.Matches(textBox1.Text);
if (matches.Count > 0) {
//tell the user
}
}
and to validate single key presses
textBox1.KeyPress += new KeyPressEventHandler(textBox1_KeyPress);
private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
// Check for a naughty character in the KeyDown event.
if (System.Text.RegularExpressions.Regex.IsMatch(e.KeyChar.ToString(), @"[^0-9^+^\-^\/^\*^\(^\)]"))
{
// Stop the character from being entered into the control since it is illegal.
e.Handled = true;
}
}

none of the answers worked for me in 2017 with capybara 2.7. I got "ArgumentError: wrong number of arguments (given 2, expected 0)"
But this did:
find('#organizationSelect').all(:css, 'option').find { |o| o.value == 'option_name_here' }.select_option
It would appear this is not possible, or at least not supported.
From the HTML5 specification:
When used to include data blocks (as opposed to scripts), the data must be embedded inline, the format of the data must be given using the type attribute, the src attribute must not be specified, and the contents of the script element must conform to the requirements defined for the format used.
