For the default scenarios I would suggest Pattern.split() as well but if you need maximum performance (especially on Android all solutions I tested are quite slow) and you only need to split by a single char, I now use my own method:
public static ArrayList<String> splitBySingleChar(final char[] s,
final char splitChar) {
final ArrayList<String> result = new ArrayList<String>();
final int length = s.length;
int offset = 0;
int count = 0;
for (int i = 0; i < length; i++) {
if (s[i] == splitChar) {
if (count > 0) {
result.add(new String(s, offset, count));
}
offset = i + 1;
count = 0;
} else {
count++;
}
}
if (count > 0) {
result.add(new String(s, offset, count));
}
return result;
}
Use "abc".toCharArray() to get the char array for a String. For example:
String s = " a bb ccc dddd eeeee ffffff ggggggg ";
ArrayList<String> result = splitBySingleChar(s.toCharArray(), ' ');
Here is an alternative implementation using XMLTABLE that allows for casting to different data types:
select
xmltab.txt
from xmltable(
'for $text in tokenize("a,b,c", ",") return $text'
columns
txt varchar2(4000) path '.'
) xmltab
;
... or if your delimited strings are stored in one or more rows of a table:
select
xmltab.txt
from (
select 'a;b;c' inpt from dual union all
select 'd;e;f' from dual
) base
inner join xmltable(
'for $text in tokenize($input, ";") return $text'
passing base.inpt as "input"
columns
txt varchar2(4000) path '.'
) xmltab
on 1=1
;
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main()
{
std::string input = "abc,def, ghi";
std::istringstream ss(input);
std::string token;
size_t pos=-1;
while(ss>>token) {
while ((pos=token.rfind(',')) != std::string::npos) {
token.erase(pos, 1);
}
std::cout << token << '\n';
}
}
You can also use regex for this:
std::vector<std::string> split(const std::string str, const std::string regex_str)
{
std::regex regexz(regex_str);
std::vector<std::string> list(std::sregex_token_iterator(str.begin(), str.end(), regexz, -1),
std::sregex_token_iterator());
return list;
}
which is equivalent to :
std::vector<std::string> split(const std::string str, const std::string regex_str)
{
std::sregex_token_iterator token_iter(str.begin(), str.end(), regexz, -1);
std::sregex_token_iterator end;
std::vector<std::string> list;
while (token_iter != end)
{
list.emplace_back(*token_iter++);
}
return list;
}
and use it like this :
#include <iostream>
#include <string>
#include <regex>
std::vector<std::string> split(const std::string str, const std::string regex_str)
{ // a yet more concise form!
return { std::sregex_token_iterator(str.begin(), str.end(), std::regex(regex_str), -1), std::sregex_token_iterator() };
}
int main()
{
std::string input_str = "lets split this";
std::string regex_str = " ";
auto tokens = split(input_str, regex_str);
for (auto& item: tokens)
{
std::cout<<item <<std::endl;
}
}
play with it online! http://cpp.sh/9sumb
you can simply use substrings, characters, etc like normal, or use actual regular expressions to do the splitting.
its also concise and C++11!
A solution using the read builtin:
IFS=':' read -a fields <<< "1:2:3:4:5"
echo "${fields[4]}"
Or, to make it more generic:
echo "${fields[-1]}" # prints the last item
This is actually on the main page of nltk.org:
>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning
... Arthur didn't feel very good."""
>>> tokens = nltk.word_tokenize(sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning',
'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']
I thought that was what the >>
operator on string streams was for:
string word; sin >> word;
I use this code to remove punctuation:
import nltk
def getTerms(sentences):
tokens = nltk.word_tokenize(sentences)
words = [w.lower() for w in tokens if w.isalnum()]
print tokens
print words
getTerms("hh, hh3h. wo shi 2 4 A . fdffdf. A&&B ")
And If you want to check whether a token is a valid English word or not, you may need PyEnchant
Tutorial:
import enchant
d = enchant.Dict("en_US")
d.check("Hello")
d.check("Helo")
d.suggest("Helo")
Do it like this:
char s[256];
strcpy(s, "one two three");
char* token = strtok(s, " ");
while (token) {
printf("token: %s\n", token);
token = strtok(NULL, " ");
}
Note: strtok
modifies the string its tokenising, so it cannot be a const char*
.
I am not sure if this fits your oracle version. On my 10g I can use pipelined table functions:
set serveroutput on
create type number_list as table of number;
-- since you want this solution
create or replace function split_csv (i_csv varchar2) return number_list pipelined
is
mystring varchar2(2000):= i_csv;
begin
for r in
( select regexp_substr(mystring,'[^,]+',1,level) element
from dual
connect by level <= length(regexp_replace(mystring,'[^,]+')) + 1
)
loop
--dbms_output.put_line(r.element);
pipe row(to_number(r.element, '999999.99'));
end loop;
end;
/
insert into foo
select column_a,column_b from
(select column_value column_a, rownum rn from table(split_csv('0.75, 0.64, 0.56, 0.45'))) a
,(select column_value column_b, rownum rn from table(split_csv('0.25, 0.5, 0.65, 0.8'))) b
where a.rn = b.rn
;
Note most of the other techniques described here break down if you're dealing with characters outside of the BMP (Unicode Basic Multilingual Plane), i.e. code points that are outside of the u0000-uFFFF range. This will only happen rarely, since the code points outside this are mostly assigned to dead languages. But there are some useful characters outside this, for example some code points used for mathematical notation, and some used to encode proper names in Chinese.
In that case your code will be:
String str = "....";
int offset = 0, strLen = str.length();
while (offset < strLen) {
int curChar = str.codePointAt(offset);
offset += Character.charCount(curChar);
// do something with curChar
}
The Character.charCount(int)
method requires Java 5+.
declare
seprator varchar2(1):=',';
dosweeklist varchar2(4000):='a,b,c';
begin
for i in (SELECT SUBSTR(dosweeklist,
case when level=1 then 1 else INSTR(dosweeklist,seprator,1,LEVEL-1)+1 end,
NVL(NULLIF(INSTR(dosweeklist,seprator,1,LEVEL),0),length(dosweeklist)+1) - case when level=1 then 1 else INSTR(dosweeklist,seprator,1,LEVEL-1)+1 end) dat
FROM dual
CONNECT BY LEVEL <= LENGTH(dosweeklist) - LENGTH(REPLACE(dosweeklist,seprator,'')) +1)
loop
dbms_output.put_line(i.dat);
end loop;
end;
/
so select query only in for loop can do the trick, by replacing dosweeklist as your delimited string and seprator as your delimited character.
Lets see output
a
b
c
It is because * is used as a metacharacter to signify one or more occurences of previous character. So if i write M* then it will look for files MMMMMM..... ! Here you are using * as the only character so the compiler is looking for the character to find multiple occurences of,so it throws the exception.:)
Wrap your reader in a BufferedReader, which maintains a buffer allowing for much faster reads overall. You can then use read() to read a single character (which you'll need to cast). You can also use readLine() to fetch an entire line and then break that into individual characters. The BufferedReader also supports marking and returning, so if you need to, you can read a line multiple times.
Generally speaking, you want to use a BufferedReader or BufferedInputStream on top of whatever stream you are actually using since the buffer they maintain will make multiple reads much faster.
This only works in Oracle 10G and greater.
Basically, you use regex_substr to do a split on the string.
Another way to accomplish this is a combination of Justus Thane's and mklement0's answers. It doesn't make sense to do it this way when you look at a one liner example, but when you're trying to mass-edit a file or a bunch of filenames it comes in pretty handy:
$test = ' One for the money '
$option = [System.StringSplitOptions]::RemoveEmptyEntries
$($test.split(' ',$option)).foreach{$_}
This will come out as:
One
for
the
money
This variant is much shorter

Just like Perl,
loop1:
for (var i in set1) {
loop2:
for (var j in set2) {
loop3:
for (var k in set3) {
break loop2; // breaks out of loop3 and loop2
}
}

Unlike C, these labels can only be used for continue

I would like to update on this, because in .NET Core multi-dimensional arrays are faster than jagged arrays. I ran the tests from John Leidegren and these are the results on .NET Core 2.0 preview 2. I increased the dimension value to make any possible influences from background apps less visible.

jagged[i][j][k] = i * j * k;

multi[i, j, k] = i * j * k;
needed 11 instructions to execute
single[i * dim * dim + j * dim + k] = i * j * k;
needed 23 instructions to execute
I wasn't able to identify why single-dimensional arrays were still faster than multi-dimensional but my guess is that it has to do with some optimalization made on the CPU
The standard Web Storage, does not say anything about the restoring any of these. So there won't be any standard way to do it. You have to go through the way the browsers implement these, or find a way to backup these before you delete them.
Without jQuery:
document.getElementById('file').onchange = function(){
var file = this.files[0];
var reader = new FileReader();
reader.onload = function(progressEvent){
// Entire file
console.log(this.result);
// By lines
var lines = this.result.split('\n');
for(var line = 0; line < lines.length; line++){
console.log(lines[line]);
}
};
reader.readAsText(file);
};
HTML:
<input type="file" name="file" id="file">
Remember to put your javascript code after the file field is rendered.
There is another way to achieve same result. In case you need to set only one parameter, for example 'height':
TextView textView = (TextView)findViewById(R.id.text_view);
ViewGroup.LayoutParams params = textView.getLayoutParams();
params.height = ViewGroup.LayoutParams.WRAP_CONTENT;
textView.setLayoutParams(params);
This is a bit circuitous because touch
doesn't take a raw time_t
value, but it should do the job pretty safely in a script. (The -r
option to date
is present in MacOS X; I've not double-checked GNU.) The 'time' variable could be avoided by writing the command substitution directly in the touch
command line.
time=$(date -r 1312603983 '+%Y%m%d%H%M.%S')
marker=/tmp/marker.$$
trap "rm -f $marker; exit 1" 0 1 2 3 13 15
touch -t $time $marker
find . -type f -newer $marker
rm -f $marker
trap 0
After a lot of research, I finally figured this one out.
DispatchQueue.main.asyncAfter(deadline: .now() + 2.0) { // Change `2.0` to the desired number of seconds.
// Code you want to be delayed
}
This creates the desired "wait" effect in Swift 3 and Swift 4.
Inspired by a part of this answer.
Not All Components.
the state
in component looks like the source of the waterfall of state of the whole APP.
So the change happens from where the setState called. The tree of renders
then get called from there. If you've used pure component, the render
will be skipped.
There's some proposition over the web (and this page) to use ViewConfiguration.getScaledTouchSlop() to have a device-scaled value for SWIPE_MIN_DISTANCE
.
getScaledTouchSlop()
is intended for the "scrolling threshold" distance, not swipe. The scrolling threshold distance has to be smaller than a "swing between page" threshold distance. For example, this function returns 12 pixels on my Samsung GS2, and the examples quoted in this page are around 100 pixels.
With API Level 8 (Android 2.2, Froyo), you've got getScaledPagingTouchSlop()
, intended for page swipe.
On my device, it returns 24 (pixels). So if you're on API Level < 8, I think "2 * getScaledTouchSlop()
" should be the "standard" swipe threshold.
But users of my application with small screens told me that it was too few... As on my application, you can scroll vertically, and change page horizontally. With the proposed value, they sometimes change page instead of scrolling.
Converting String to Json Object by using org.json.simple.JSONObject
private static JSONObject createJSONObject(String jsonString){
JSONObject jsonObject=new JSONObject();
JSONParser jsonParser=new JSONParser();
if ((jsonString != null) && !(jsonString.isEmpty())) {
try {
jsonObject=(JSONObject) jsonParser.parse(jsonString);
} catch (org.json.simple.parser.ParseException e) {
e.printStackTrace();
}
}
return jsonObject;
}
jQuery would be the easiest way if you want to use it, but this should work.
function showHide(){
var e = document.getElementById('e');
if ( e.style.display !== 'none' ) {
e.style.display = 'none';
} else {
e.style.display = '';
}
}
shape()
consists of array having two arguments rows and columns.
if you search shape[0]
then it will gave you the number of rows.
shape[1]
will gave you number of columns.
A word boundary is a position that is either preceded by a word character and not followed by one, or followed by a word character and not preceded by one.
I used dir /s /b /o:n /a:d
, and it worked perfectly, just make sure you let the file finish writing, or you'll have an incomplete list.
i add this shell script to convert jsp files from IS

Try Like This: For SQL SERVER 2008+
SELECT c.name AS ColName, t.name AS TableName
FROM sys.columns c
JOIN sys.tables t ON c.object_id = t.object_id
WHERE c.name LIKE '%MyColumnaName%'
Or
SELECT COLUMN_NAME, TABLE_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME LIKE '%MyName%'
Or Something Like This:
SELECT name
FROM sys.tables
WHERE OBJECT_ID IN ( SELECT id
FROM syscolumns
WHERE name like '%COlName%' )
If you want to see the difference as just the names of the files changed then use:
git diff --name-status <remote-branch> <local-branch>
,
else this would show all differences between the two branches:
git diff <remote-branch> <local-branch>
I was looking for a similar solution, base on what was suggested on this thread, I use the following
DateTime.Now.ToString("MM/dd/yyyy hh:mm:ss.fff")
, and it work like charm. Note: that .fff
are the precision numbers that you wish to capture.
List list1 = new ArrayList();
list1.add("one");
list1.add("three");
list1.add("four");
List list2 = new ArrayList();
list2.add("one");
list2.add("two");
list2.add("three");
list2.add("four");
list2.add("five");
list2.stream().filter( x -> !list1.contains(x) ).forEach(x -> System.out.println(x));
The output is:
two
five
To conditionally check the length of the string, use CASE

This is a good reference, it helped me switch my http
requests to httpClient
.
It compares the two in terms of differences and gives code examples.
This is just a few differences I dealt with while changing services to httpclient in my project (borrowing from the article I mentioned) :
import {HttpModule} from '@angular/http';
import {HttpClientModule} from '@angular/common/http';
this.http.get(url)
// Extract the data in HTTP Response (parsing)
.map((response: Response) => response.json() as GithubUser)
.subscribe((data: GithubUser) => {
// Display the result
console.log('TJ user data', data);
});
this.http.get(url)
.subscribe((data: GithubUser) => {
// Data extraction from the HTTP response is already done
// Display the result
console.log('TJ user data', data);
});
Note: You no longer have to extract the returned data explicitly; by default, if the data you get back is type of JSON, then you don't have to do anything extra.
But, if you need to parse any other type of response like text or blob, then make sure you add the responseType
in the request. Like so:
responseType
option: this.http.get(url, {responseType: 'blob'})
.subscribe((data) => {
// Data extraction from the HTTP response is already done
// Display the result
console.log('TJ user data', data);
});
I also used interceptors for adding the token for my authorization to every request, reference.
like so:
@Injectable()
export class MyFirstInterceptor implements HttpInterceptor {
constructor(private currentUserService: CurrentUserService) { }
intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
// get the token from a service
const token: string = this.currentUserService.token;
// add it if we have one
if (token) {
req = req.clone({ headers: req.headers.set('Authorization', 'Bearer ' + token) });
}
// if this is a login-request the header is
// already set to x/www/formurl/encoded.
// so if we already have a content-type, do not
// set it, but if we don't have one, set it to
// default --> json
if (!req.headers.has('Content-Type')) {
req = req.clone({ headers: req.headers.set('Content-Type', 'application/json') });
}
// setting the accept header
req = req.clone({ headers: req.headers.set('Accept', 'application/json') });
return next.handle(req);
}
}
Its a pretty nice upgrade!
column_obj != None
will produce a IS NOT NULL
constraint:
In a column context, produces the clause
a != b
. If the target isNone
, produces aIS NOT NULL
.
or use isnot()
(new in 0.7.9):
Implement the
IS NOT
operator.Normally,
IS NOT
is generated automatically when comparing to a value ofNone
, which resolves toNULL
. However, explicit usage ofIS NOT
may be desirable if comparing to boolean values on certain platforms.
Demo:
>>> from sqlalchemy.sql import column
>>> column('YourColumn') != None
<sqlalchemy.sql.elements.BinaryExpression object at 0x10c8d8b90>
>>> str(column('YourColumn') != None)
'"YourColumn" IS NOT NULL'
>>> column('YourColumn').isnot(None)
<sqlalchemy.sql.elements.BinaryExpression object at 0x104603850>
>>> str(column('YourColumn').isnot(None))
'"YourColumn" IS NOT NULL'
The best solution ¹for a mathematician is to use Python.
C++ operator overloading has little to do with it. You can't overload operators for built-in types. What you want is simply a function. Of course you can use C++ templating to implement that function for all relevant types with just 1 piece of code.
The standard C library provides fmod
, if I recall the name correctly, for floating point types.
For integers you can define a C++ function template that always returns non-negative remainder (corresponding to Euclidian division) as ...
#include <stdlib.h> // abs
template< class Integer >
auto mod( Integer a, Integer b )
-> Integer
{
Integer const r = a%b;
return (r < 0? r + abs( b ) : r);
}
... and just write mod(a, b)
instead of a%b
.
Here the type Integer
needs to be a signed integer type.
If you want the common math behavior where the sign of the remainder is the same as the sign of the divisor, then you can do e.g.
template< class Integer >
auto floor_div( Integer const a, Integer const b )
-> Integer
{
bool const a_is_negative = (a < 0);
bool const b_is_negative = (b < 0);
bool const change_sign = (a_is_negative != b_is_negative);
Integer const abs_b = abs( b );
Integer const abs_a_plus = abs( a ) + (change_sign? abs_b - 1 : 0);
Integer const quot = abs_a_plus / abs_b;
return (change_sign? -quot : quot);
}
template< class Integer >
auto floor_mod( Integer const a, Integer const b )
-> Integer
{ return a - b*floor_div( a, b ); }
… with the same constraint on Integer
, that it's a signed type.
¹ Because Python's integer division rounds towards negative infinity.
You would need to have an instance of ClassA within ClassB or have ClassB inherit ClassA
class ClassA {
public function getName() {
echo $this->name;
}
}
class ClassB extends ClassA {
public function getName() {
parent::getName();
}
}
Without inheritance or an instance method, you'd need ClassA to have a static method
class ClassA {
public static function getName() {
echo "Rawkode";
}
}
--- other file ---
echo ClassA::getName();
If you're just looking to call the method from an instance of the class:
class ClassA {
public function getName() {
echo "Rawkode";
}
}
--- other file ---
$a = new ClassA();
echo $a->getName();
Regardless of the solution you choose, require 'ClassA.php
is needed.
If you are using ES6 and Express, try this destructuring
approach:
const {id, since, fields, anotherField} = request.query;
In context:
const express = require('express');
const app = express();
app.get('/', function(req, res){
const {id, since, fields, anotherField} = req.query;
});
app.listen(3000);
You can use default values with destructuring
too:
// sample request for testing_x000D_
const req = {_x000D_
query: {_x000D_
id: '123',_x000D_
fields: ['a', 'b', 'c']_x000D_
}_x000D_
}_x000D_
_x000D_
const {_x000D_
id,_x000D_
since = new Date().toString(),_x000D_
fields = ['x'],_x000D_
anotherField = 'default'_x000D_
} = req.query;_x000D_
_x000D_
console.log(id, since, fields, anotherField)
_x000D_
Input => '["3","6","16","120"]'
Type conversion I used => (int)$s;
function Str_Int_Arr($data){
$h=[];
$arr=substr($data,1,-1);
//$exp=str_replace( ",","", $arr);
$exp=str_replace( "\"","", $arr);
$s='';
$m=0;
foreach (str_split($exp) as $k){
if('0'<= $k && '9'>$k || $k =","){
if('0' <= $k && '9' > $k){
$s.=$k;
$h[$m]=(int)$s;
}else{
$s="";
$m+=1;
}
}
}
return $h;
}
var_dump(Str_Int_Arr('["3","6","16","120"]'));
Output:
array(4) {
[0]=>
int(3)
[1]=>
int(6)
[2]=>
int(16)
[3]=>
int(120)
}
Thanks
You should not need to access Maven-specific files to get the version information of any given library/class.
You can simply use getClass().getPackage().getImplementationVersion()
to get the version information that is stored in a .jar-files MANIFEST.MF
. Luckily Maven is smart enough Unfortunately Maven does not write the correct information to the manifest as well by default!
Instead one has to modify the <archive>
configuration element of the maven-jar-plugin
to set addDefaultImplementationEntries
and addDefaultSpecificationEntries
to true
, like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addDefaultImplementationEntries>true</addDefaultImplementationEntries>
<addDefaultSpecificationEntries>true</addDefaultSpecificationEntries>
</manifest>
</archive>
</configuration>
</plugin>
Ideally this configuration should be put into the company pom
or another base-pom.
Detailed documentation of the <archive>
element can be found in the Maven Archive documentation.
In PHP:
$driver->navigate()->refresh();
Here is an awesome and precise explanation I found.
TIMESTAMP used to track changes of records, and update every time when the record is changed. DATETIME used to store specific and static value which is not affected by any changes in records.
TIMESTAMP also affected by different TIME ZONE related setting. DATETIME is constant.
TIMESTAMP internally converted a current time zone to UTC for storage, and during retrieval convert the back to the current time zone. DATETIME can not do this.
TIMESTAMP is 4 bytes and DATETIME is 8 bytes.
TIMESTAMP supported range: ‘1970-01-01 00:00:01' UTC to ‘2038-01-19 03:14:07' UTC DATETIME supported range: ‘1000-01-01 00:00:00' to ‘9999-12-31 23:59:59'

If anyone is looking for a rowspan on both the left AND on the right, here is how you can do it:
table { _x000D_
border-collapse: collapse;_x000D_
}_x000D_
_x000D_
td {_x000D_
padding: 20px; _x000D_
border: 1px solid black; _x000D_
text-align: center;_x000D_
}
_x000D_
<table>_x000D_
<tbody>_x000D_
<tr>_x000D_
<td rowspan="2">LEFT</td>_x000D_
<td> 1 </td>_x000D_
<td> 2 </td>_x000D_
<td> 3 </td>_x000D_
<td> 4 </td>_x000D_
<td rowspan="2">RIGHT</td>_x000D_
</tr>_x000D_
<tr>_x000D_
<td> 5 </td>_x000D_
<td> 6 </td>_x000D_
<td> 7 </td>_x000D_
<td> 8 </td>_x000D_
</tr>_x000D_
<tr>_x000D_
<td> - </td>_x000D_
<td> - </td>_x000D_
<td> - </td>_x000D_
<td> - </td>_x000D_
<td> - </td>_x000D_
<td> - </td>_x000D_
</tr>_x000D_
</tbody>_x000D_
</table>
_x000D_
Alternatively, if you want to add the LEFT and RIGHT to an existing rowset, you can achieve the same result by throwing them in with a collapsed colspan
in between:
table {_x000D_
border-collapse: collapse;_x000D_
}_x000D_
_x000D_
td {_x000D_
padding: 20px; _x000D_
border: 1px solid black; _x000D_
text-align: center;_x000D_
}
_x000D_
<table>_x000D_
<tbody>_x000D_
<tr>_x000D_
<td rowspan="3">LEFT</td>_x000D_
<td colspan="4" style="padding: 0; border-bottom: solid 1px transparent;"></td>_x000D_
<td rowspan="3">RIGHT</td>_x000D_
</tr>_x000D_
<tr>_x000D_
<td> 1 </td>_x000D_
<td> 2 </td>_x000D_
<td> 3 </td>_x000D_
<td> 4 </td>_x000D_
</tr>_x000D_
<tr>_x000D_
<td> 5 </td>_x000D_
<td> 6 </td>_x000D_
<td> 7 </td>_x000D_
<td> 8 </td>_x000D_
</tr>_x000D_
<tr>_x000D_
<td> - </td>_x000D_
<td> - </td>_x000D_
<td> - </td>_x000D_
<td> - </td>_x000D_
<td> - </td>_x000D_

If the OpenSSL headers are in the openssl
sub-directory of the current directory, use:
gcc -I. -o Opentest Opentest.c -lcrypto
The pre-processor looks to create a name such as "./openssl/ssl.h
" from the ".
" in the -I
option and the name specified in angle brackets. If you had specified the names in double quotes (#include "openssl/ssl.h"
), you might never have needed to ask the question; the compiler on Unix usually searches for headers enclosed in double quotes in the current directory automatically, but it does not do so for headers enclosed in angle brackets (#include <openssl/ssl.h>
). It is implementation defined behaviour.
You don't say where the OpenSSL libraries are - you might need to add an appropriate option and argument to specify that, such as '-L /opt/openssl/lib
'.
With the Material Components library you can use the CircularProgressIndicator
:
Something like:
<com.google.android.material.progressindicator.CircularProgressIndicator
android:indeterminate="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:indicatorColor="@array/progress_colors"
app:indicatorSize="xxdp"
app:showAnimationBehavior="inward"/>
where array/progress_colors
is an array with the colors:
<integer-array name="progress_colors">
<item>@color/yellow_500</item>
<item>@color/blue_700</item>
<item>@color/red_500</item>
</integer-array>
Note: it requires at least the version 1.3.0
You have to use SpannableString for that :
String mystring=new String("Hello.....");
SpannableString content = new SpannableString(mystring);
content.setSpan(new UnderlineSpan(), 0, mystring.length(), 0);
yourtextview.setText(content);
Update : You can refer my answer on Underling TextView's here in all possible ways.
System.IO.Path.GetTempPath()
The path specified by the TMP

The path specified by the USERPROFILE
environment variable.
The Windows directory.
You cannot open new fragments. Fragments need to be always hosted by an activity. If the fragment is in the same activity (eg tabs) then the back key navigation is going to be tricky I am assuming that you want to open a new screen with that fragment.
So you would simply create a new activity and put the new fragment in there. That activity would then react to the intent either explicitly via the activity class or implicitly via intent filter
s.
You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:
https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899
In this example, question 1, "Name", has an ID of 726721210
, while question 2, "Birthday" is 787184751
. Questions 3 and 4 are blank.
You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:
function buildUrls() {
var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1"); // Email, Name, Birthday
var data = ss.getDataRange().getValues();
// Skip headers, then build URLs for each row in Sheet1.
for (var i = 1; i < data.length; i++ ) {
var url = template.replace('##Name##',escape(data[i][1]))
.replace('##Birthday##',data[i][2].yyyymmdd()); // see yyyymmdd below
Logger.log(url); // You could do something more useful here.
}
};
This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.
Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.
Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0]
is "Name", [1]
is "Birthday", and so on.
We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.
(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)
/**
* Use Form API to generate pre-filled form URLs
*/
function betterBuildUrls() {
var ss = SpreadsheetApp.getActive();
var sheet = ss.getSheetByName("Sheet1");
var data = ss.getDataRange().getValues(); // Data for pre-fill
var formUrl = ss.getFormUrl(); // Use form attached to sheet
var form = FormApp.openByUrl(formUrl);
var items = form.getItems();
// Skip headers, then build URLs for each row in Sheet1.
for (var i = 1; i < data.length; i++ ) {
// Create a form response object, and prefill it
var formResponse = form.createResponse();
// Prefill Name
var formItem = items[0].asTextItem();
var response = formItem.createResponse(data[i][1]);
formResponse.withItemResponse(response);
// Prefill Birthday
formItem = items[1].asDateItem();
response = formItem.createResponse(data[i][2]);
formResponse.withItemResponse(response);
// Get prefilled form URL
var url = formResponse.toPrefilledUrl();
Logger.log(url); // You could do something more useful here.
}
};
Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd
. This helper function extends the Date object with a new method to handle the conversion.
When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975
you could use 5/9/1975
.)
// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
var yyyy = this.getFullYear().toString();
var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
var dd = this.getDate().toString();
return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};
Use it to access class in Javascript.
<script type="text/javascript">
var var_name = document.getElementsByClassName("class_name")[0];
</script>
The function you need is CInt
.
ie CInt(PrinterLabel)
See Type Conversion Functions (Visual Basic) on MSDN
Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!
I'm not sure how you think you can do it other than character-by-character -- it's inherently a character-by-character operation. There is certainly code out there to do this for you, but there is no "simpler" way than doing it character-by-character.
First, you need to strip the 0b
prefix, and left-zero-pad the string so it's length is divisible by 8, to make dividing the bitstring up into characters easy:
bitstring = bitstring[2:]
bitstring = -len(bitstring) % 8 * '0' + bitstring
Then you divide the string up into blocks of eight binary digits, convert them to ASCII characters, and join them back into a string:
string_blocks = (bitstring[i:i+8] for i in range(0, len(bitstring), 8))
string = ''.join(chr(int(char, 2)) for char in string_blocks)
If you actually want to treat it as a number, you still have to account for the fact that the leftmost character will be at most seven digits long if you want to go left-to-right instead of right-to-left.
Update the bind-address = 0.0.0.0

and from the mysql command line allow the root
user to connect from any Ip.

sudo service mysql restart
For those who struggle at capturing Enter key on TextBox or other input control, if your Form has AcceptButton defined, you will not be able to use KeyDown event to capture Enter.
What you should do is to catch the Enter key at form level. Add this code to the form:
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if ((this.ActiveControl == myTextBox) && (keyData == Keys.Return))
{
//do something
return true;
}
else
{
return base.ProcessCmdKey(ref msg, keyData);
}
}
Here's one way:
import os
import shutil
def copy_over(path, from_name, to_name):
for path, dirname, fnames in os.walk(path):
for fname in fnames:
if fname == from_name:
shutil.copy(os.path.join(path, from_name), os.path.join(path, to_name))
copy_over('.', 'index.tpl', 'index.html')
If you are using CMake, there are some ways that you could solve it:
Solution 1: The most elegant one
add_executable(...)
target_include_directories(...)
target_link_libraries(target_name pthread)
Solution 2: using CMake find_package
find_package(Threads REQUIRED) # this will generate the flag for CMAKE_THREAD_LIBS_INIT
add_executable(...)
target_include_directories(...)
target_link_libraries(target_name ${CMAKE_THREAD_LIBS_INIT})
Solution 3: Change CMake flags
# e.g. with C++ 17, change to other version if you need
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17 -pthread")

For to use looping to get all arguments and in pure batch:
Obs: For using without: ?*&<>
@echo off && setlocal EnableDelayedExpansion
for %%Z in (%*)do set "_arg_=%%Z" && set/a "_cnt+=1+0" && call set "_arg_[!_cnt!]=!_arg_!")
:: write/test these arguments/parameters ::
for /l %%l in (1 1 !_cnt!)do echo/ The argument n:%%l is: !_arg_[%%l]!
goto :eof
Your code is ready to do something with the argument number where it needs, like...
@echo off && setlocal EnableDelayedExpansion
for %%Z in (%*)do set "_arg_=%%Z" && set/a "_cnt+=1+0" && call set "_arg_[!_cnt!]=!_arg_!"
echo= !_arg_[1]! !_arg_[2]! !_arg_[2]!> log.txt
To get the value of the selected item of a listbox then use the following.
For Single Column ListBox:
ListBox1.List(ListBox1.ListIndex)
For Multi Column ListBox:
ListBox1.Column(column_number, ListBox1.ListIndex)
This avoids looping and is extremely more efficient.

In this Yahoo Developer Network (archived link) article it is suggested that if you absolutely must use a background-image instead of img element and alt attribute, use ARIA attributes as follows:
<div role="img" aria-label="adorable puppy playing on the grass">
...
</div>
The use case in the article describes how Flickr chose to use background images because performance was greatly improved on mobile devices.
Here is a solution I made using the above ideas that can be used for TextBoxFor and PasswordFor:
public static class HtmlHelperEx
{
public static MvcHtmlString TextBoxWithPlaceholderFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper,
Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
{
var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
return htmlHelper.TextBoxFor(expression, htmlAttributes.AddAttribute("placeholder", metadata.Watermark));
}
public static MvcHtmlString PasswordWithPlaceholderFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper,
Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
{
var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
return htmlHelper.PasswordFor(expression, htmlAttributes.AddAttribute("placeholder", metadata.Watermark));
}
}
public static class HtmlAttributesHelper
{
public static IDictionary<string, object> AddAttribute(this object htmlAttributes, string name, object value)
{
var dictionary = htmlAttributes == null ? new Dictionary<string, object>() : htmlAttributes.ToDictionary();
if (!String.IsNullOrWhiteSpace(name) && value != null && !String.IsNullOrWhiteSpace(value.ToString()))
dictionary.Add(name, value);
return dictionary;
}
public static IDictionary<string, object> ToDictionary(this object obj)
{
return TypeDescriptor.GetProperties(obj)
.Cast<PropertyDescriptor>()
.ToDictionary(property => property.Name, property => property.GetValue(obj));
}
}
You can also get some sample swagger files online to verify this(if you have errors in your swagger doc).
It depends on what you're trying to achieve after changing the Java file. Until you want to test the maven process, you never need to do anything. Eclipse/MyEclipse will build what is necessary and put the output in the appropriate place within your project. You can also run or deploy it (if it's a web project, for example), without your needing to explicitly do anything with maven. In the end, to install your project in the maven repository, you will need to do a maven install. You may also have other maven goals that you wish to execute, which MyEclipse won't do automatically.
As I say, it depends on what you want to do.
For some reason @Alejandro Gracia answer starts working only after a few second.
I found a solution that blocks the RecyclerView instantaneously:
recyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
return true;
}
@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
});
grep -cvE '(^\s*[/*])|(^\s*$)' foo
-c = count
-v = exclude
-E = extended regex
'(comment lines) OR (empty lines)'
where
^ = beginning of the line
\s = whitespace
* = any number of previous characters or none
[/*] = either / or *
| = OR
$ = end of the line
I post this becaus other options gave wrong answers for me. This worked with my java source, where comment lines start with / or * (i use * on every line in multi-line comment).
Go to the file location where the POM is stored and open cmd. Then type "mvn --v" to check the maven version and java runtime provided. Check runtime attribute and if it is "C:\Program Files\Java\jre1.8.0_191" or even close to a JRE, go to environment variables and add a new "system variable" called "JAVA_HOME" with a value "C:\Program Files\Java\jdk1.8.0_191".
Reopen the cmd and then "clean install" the project.
The following will work in MVC 4
@Html.HiddenFor(x => x.CRN, new { @Value = "1" });
@Value property is case sensitive. You need a capital 'V' on @Value.
Here is my model

Here is what is output in html when you look in the browser
<input value="1" data-val="true" data-val-number="The field CRN must be a number." data-val-required="The CRN field is required." id="CRN" name="CRN" type="hidden" value="1"/>
Here is my method
[HttpPost]
public ActionResult MyMethod(MyViewModel viewModel)
{
int crn = viewModel.CRN;
}
I know you asked how to do this, but the answer is you should not do this.
Instead, have a application.properties
, application-default.properties
application-dev.properties
etc., and switch profiles via args to the JVM: e.g. -Dspring.profiles.active=dev
You can also override some things at test time using @TestPropertySource
Ideally everything should be in source control so that there are no surprises e.g. How do you know what properties are sitting there in your server location, and which ones are missing? What happens if developers introduce new things?

You have to enable replicatoon, if I'm right. The information is from this answer from this question: How to listen for changes to a MongoDB collection?
You can define a new udf
when adding a column_name
:
u_f = F.udf(lambda :yourstring,StringType())
a.select(u_f().alias('column_name')
If you don't know wether you have enough next elements in your container or not, you need to check against the end of your container between each increment. Neither ++ nor std::advance will do it for you.
if( ++iter == collection.end())
... // stop
if( ++iter == collection.end())
... // stop
You may even roll your own bound-secure advance function.
If you are sure that you will not go past the end, then std::advance( iter, 2 ) is the best solution.
Perhaps the pandas interface has changed since @Rutger answered, but in the version I'm using (0.15.2), the date_parser
function receives a list of dates instead of a single value. In this case, his code should be updated like so:
dateparse = lambda dates: [pd.datetime.strptime(d, '%Y-%m-%d %H:%M:%S') for d in dates]
df = pd.read_csv(infile, parse_dates=['datetime'], date_parser=dateparse)
It's not fancy I known but you could use a callback class, create a hostbuilder and set the configuration to a static property.
For asp core 2.2:
using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using System;
namespace Project
{
sealed class Program
{
#region Variables
/// <summary>
/// Last loaded configuration
/// </summary>
private static IConfiguration _Configuration;
#endregion
#region Properties
/// <summary>
/// Default application configuration
/// </summary>
internal static IConfiguration Configuration
{
get
{
// None configuration yet?
if (Program._Configuration == null)
{
// Create the builder using a callback class
IWebHostBuilder builder = WebHost.CreateDefaultBuilder().UseStartup<CallBackConfiguration>();
// Build everything but do not initialize it
builder.Build();
}
// Current configuration
return Program._Configuration;
}
// Update configuration
set => Program._Configuration = value;
}
#endregion
#region Public
/// <summary>
/// Start the webapp
/// </summary>
public static void Main(string[] args)
{
// Create the builder using the default Startup class
IWebHostBuilder builder = WebHost.CreateDefaultBuilder(args).UseStartup<Startup>();
// Build everything and run it
using (IWebHost host = builder.Build())
host.Run();
}
#endregion
#region CallBackConfiguration
/// <summary>
/// Aux class to callback configuration
/// </summary>
private class CallBackConfiguration
{
/// <summary>
/// Callback with configuration
/// </summary>
public CallBackConfiguration(IConfiguration configuration)
{
// Update the last configuration
Program.Configuration = configuration;
}
/// <summary>
/// Do nothing, just for compatibility
/// </summary>
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
//
}
}
#endregion
}
}
So now on you just use the static Program.Configuration at any other class you need it.
In Python 3.4 or later version, the pythonic way would be:
import os
from contextlib import suppress
with suppress(OSError):
os.remove(filename)
To me plurals manipulate the collection, whereas singulars manipulate the item inside that collection.
Collection allows the methods GET / POST / DELETE
Item allows the methods GET / PUT / DELETE
For example
POST on /students will add a new student in the school.
DELETE on /students will remove all the students in the school.
DELETE on /student/123 will remove student 123 from the school.
It might feel like unimportant but some engineers sometimes forget the id. If the route was always plural and performed a DELETE, you might accidentally wipe your data. Whereas missing the id on the singular will return a 404 route not found.
To further expand the example if the API was supposed to expose multiple schools, then something like
DELETE on /school/abc/students will remove all the students in the school abc
.
Choosing the right word sometimes is a challenge on its own, but I like to maintain plurality for the collection. E.g. cart_items
or cart/items
feels right. In contrast deleting cart
, deletes the cart object it self and not the items within the cart ;).
The people above have already pretty much explained the issue, but one thing that might make things clear is that, though people use <br/>
and such all the time in HTML documents, any /
in such a position is basically ignored, and only used when trying to make something both parseable as XML and HTML. Try <p/>foo</p>
, for example, and you get a regular paragraph.
A little quickie for template tags:
@register.filter
def pdb(element):
import pdb; pdb.set_trace()
return element
Now, inside a template you can do {{ template_var|pdb }}
and enter a pdb session (given you're running the local devel server) where you can inspect element
to your heart's content.
It's a very nice way to see what's happened to your object when it arrives at the template.

You can't achieve POST requests using urllib
(only for GET), instead try using requests
module, e.g.:
Example 1.0:
import requests
base_url="www.server.com"
final_url="/{0}/friendly/{1}/url".format(base_url,any_value_here)
payload = {'number': 2, 'value': 1}
response = requests.post(final_url, data=payload)
print(response.text) #TEXT/HTML
print(response.status_code, response.reason) #HTTP
Example 1.2:
>>> import requests
>>> payload = {'key1': 'value1', 'key2': 'value2'}
>>> r = requests.post("http://httpbin.org/post", data=payload)
>>> print(r.text)
{
...
"form": {
"key2": "value2",
"key1": "value1"
},
...
}
Example 1.3:
>>> import json
>>> url = 'https://api.github.com/some/endpoint'
>>> payload = {'some': 'data'}
>>> r = requests.post(url, data=json.dumps(payload))
I had the same issue. It seems the easiest solution is to just remove the remote, readd it, and fetch.
Bundler now has a bundle remove GEM_NAME
command (since v1.17.0, 25 October 2018).
As per the JSON docs at Mozilla, JSON.Stringify
has a second parameter censor
which can be used to filter/ignore children items while parsing the tree. However, perhaps you can avoid the circular references.
In Node.js we cannot. So we can do something like this:
function censor(censor) {
var i = 0;
return function(key, value) {
if(i !== 0 && typeof(censor) === 'object' && typeof(value) == 'object' && censor == value)
return '[Circular]';
if(i >= 29) // seems to be a harded maximum of 30 serialized objects?
return '[Unknown]';
++i; // so we know we aren't using the original object anymore
return value;
}
}
var b = {foo: {bar: null}};
b.foo.bar = b;
console.log("Censoring: ", b);
console.log("Result: ", JSON.stringify(b, censor(b)));
The result:
Censoring: { foo: { bar: [Circular] } }
Result: {"foo":{"bar":"[Circular]"}}
Unfortunately there seems to be a maximum of 30 iterations before it automatically assumes it's circular. Otherwise, this should work. I even used areEquivalent
from here, but JSON.Stringify
still throws the exception after 30 iterations. Still, it's good enough to get a decent representation of the object at a top level, if you really need it. Perhaps somebody can improve upon this though? In Node.js for an HTTP request object, I'm getting:

Try This
final Button button = (Button) findViewById(R.id.button_id);
button.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_UP) {
button.setBackgroundColor(Color.RED);
} else if(event.getAction() == MotionEvent.ACTION_DOWN) {
button.setBackgroundColor(Color.BLUE);
}
return false;
}
});
f = open('test.txt','r')
for line in f.xreadlines():
print line
f.close()
I would argue that the only safe mechanism here is to use the String name()
value. When writing to the DB, you could use a sproc to insert the value and when reading, use a View. In this manner, if the enums change, there is a level of indirection in the sproc/view to be able to present the data as the enum value without "imposing" this on the DB.
As @xecaps12 said, the simplest/efficient approach is to change your Maven settings file (~/.m2/settings.xml) but if it is a default settings for you, you can also set it like that
<profile>
<id>downloadSources</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<downloadSources>true</downloadSources>
<downloadJavadocs>true</downloadJavadocs>

For Sybase aka SQL Anywhere the following command outputs the structure of a table:
DESCRIBE 'TABLE_NAME';
def split_and_save_df(df, name, size, output_dir):
"""
Split a df and save each chunk in a different csv file.
Parameters:
df : pandas df to be splitted
name : name to give to the output file
size : chunk size
output_dir : directory where to write the divided df
"""
import os
for i in range(0, df.shape[0],size):
start = i
end = min(i+size-1, df.shape[0])
subset = df.loc[start:end]
output_path = os.path.join(output_dir,f"{name}_{start}_{end}.csv")
print(f"Going to write into {output_path}")
subset.to_csv(output_path)
output_size = os.stat(output_path).st_size
print(f"Wrote {output_size} bytes")
We can convert the bools to integers and perform this easy check:
(int(a) + int(b) + int(c)) >= 2
This style is for full reset for tables - cellpadding, cellspacing and borders.
I had this style in my reset.css file:
table{
border:0; /* Replace border */
border-spacing: 0px; /* Replace cellspacing */
border-collapse: collapse; /* Patch for Internet Explorer 6 and Internet Explorer 7 */
}
table td{
padding: 0px; /* Replace cellpadding */
}
The best and easiest way to clear a JLIST is:
myJlist.setListData(new String[0]);
If you are developing an Ionic app be sure to include jquery and jquery-ui before ionic.bundle.js!
such a waste of time for something so trivial :(
or try this (from http://drupal.org/node/870058)
Download wkhtmltopdf. Or better install it with a package manager:
sudo apt-get install wkhtmltopdf
Extract it and move it to /usr/local/bin/
wkhtmltopdf
so that now you have an executable at /usr/local/bin/wkhtmltopdf
sudo chmod a+x /usr/local/bin/wkhtmltopdf
Install required support packages.
sudo apt-get install openssl build-essential xorg libssl-dev
Check to see if it works: run
/usr/local/bin/wkhtmltopdf http://www.google.com test.pdf
If it works, then you are done. If you get the error "Cannot connect to X server" then continue to number 7.
We need to run it headless on a 'virtual' x server. We will do this with a package called xvfb.
sudo apt-get install xvfb
We need to write a little shell script to wrap wkhtmltopdf in xvfb. Make a file called wkhtmltopdf.sh
and add the following:
xvfb-run -a -s "-screen 0 640x480x16" wkhtmltopdf "$@"
Move this shell script to /usr/local/bin
, and set permissions:
sudo chmod a+x /usr/local/bin/wkhtmltopdf.sh
Check to see if it works once again: run
/usr/local/bin/wkhtmltopdf.sh http://www.google.com test.pdf
Note that http://www.google.com may throw an error like "A finished ResourceObject received a loading finished signal. This might be an indication of an iframe taking to long to load." You may want to test with a simpler page like http://www.example.com
.
Yes, It's deprecated. Spent yesterday rewriting code to use Window.open and PostMessage instead.
Using tail -f output

If you install Eclipse properly then:

.Let me show you a little trick.
As Arkanciscan said, you can use CSS3 transitions. But his solution looks different from the original tag.
What you really need to do is this:
@keyframes blink {_x000D_
50% {_x000D_
opacity: 0.0;_x000D_
}_x000D_
}_x000D_
@-webkit-keyframes blink {_x000D_
50% {_x000D_
opacity: 0.0;_x000D_
}_x000D_
}_x000D_
.blink {_x000D_
animation: blink 1s step-start 0s infinite;_x000D_
-webkit-animation: blink 1s step-start 0s infinite;_x000D_
}
_x000D_
<span class="blink">Blink</span>
_x000D_
Following rokkuchan's answer, just a little upgrade:
List<string> listOfStrings = new List<string> {"abc", "123", "ghi"};
int index = listOfStrings.FindIndex(ind => ind.Equals("123"));
if (index > -1)
listOfStrings[index] = "def";
This is more advice than a specific answer, but my suggestion is to convert dates to date variables immediately, rather than keeping them as strings. This way you can use date (and time) functions on them, rather than trying to use very troublesome workarounds.
As pointed out, the lubridate package has nice extraction functions.
For some projects, I have found that piecing dates out from the start is helpful: create year, month, day (of month) and day (of week) variables to start with. This can simplify summaries, tables and graphs, because the extraction code is separate from the summary/table/graph code, and because if you need to change it, you don't have to roll out those changes in multiple spots.
The information provided in this answer can lead to insecure programming practices.
The information provided here depends highly on MySQL configuration, including (but not limited to) the program version, the database client and character-encoding used.
See http://dev.mysql.com/doc/refman/5.0/en/string-literals.html
MySQL recognizes the following escape sequences. \0 An ASCII NUL (0x00) character. \' A single quote (“'”) character. \" A double quote (“"”) character. \b A backspace character. \n A newline (linefeed) character. \r A carriage return character. \t A tab character. \Z ASCII 26 (Control-Z). See note following the table. \\ A backslash (“\”) character. \% A “%” character. See note following the table. \_ A “_” character. See note following the table.
So you need
select * from tablename where fields like "%string \"hi\" %";
Although as Bill Karwin notes below, using double quotes for string delimiters isn't standard SQL, so it's good practice to use single quotes. This simplifies things:
select * from tablename where fields like '%string "hi" %';
Always show errors on a testing server. Never show errors on a production server.
Write a script to determine whether the page is on a local, testing, or live server, and set $state to "local", "testing", or "live". Then:
if( $state == "local" || $state == "testing" )
{
ini_set( "display_errors", "1" );
error_reporting( E_ALL & ~E_NOTICE );
}
else
{
error_reporting( 0 );
}
Another tricky solution is to name elements of list and attach
it:
list_name = list(
head(iris),
head(swiss),
head(airquality)
)
names(list_name) <- paste("orca", seq_along(list_name), sep="")
attach(list_name)
orca1

# 1 5.1 3.5 1.4 0.2 setosa
# 2 4.9 3.0 1.4 0.2 setosa
# 3 4.7 3.2 1.3 0.2 setosa
# 4 4.6 3.1 1.5 0.2 setosa

the encode ur conver and adds all the extra elements like for spaces and all. so u can easily fetch plane text code from db and use it without worring about the special characters to be added
FWIW CloudFront supports streaming as well. Might be better than plain streaming from instances.
Use a simple Faraday cage to block or limit the external RF signal level.
You can make your own with aluminum foil. The openings should be smaller than the wavelength of your data service if that's what you want to block.
800 Mhz has a 37 cm (14") wavelength, 1900 Mhz has a 16 cm (6") wavelength.
This works better with an actual device than with the simulator since the Mac is hard to work on when inside the Faraday cage ;-)
How about pass
?
Main thing to worry about is how would you notify the elevator that it needs to move up or down. and also if you are going to have a centralized class to control this behavior and how could you distribute the control.
It seems like it can be very simple or very complicated. If we don't take concurrency or the time for an elevator to get to one place, then it seems like it will be simple since we just need to check the states of elevator, like is it moving up or down, or standing still. But if we make Elevator implement Runnable, and constantly check and synchronize a queue (linkedList). A Controller class will assign which floor to go in the queue. When the queue is empty, the run() method will wait (queue.wait() ), when a floor is assigned to this elevator, it will call queue.notify() to wake up the run() method, and run() method will call goToFloor(queue.pop()). This will make the problem too complicated. I tried to write it on paper, but dont think it works. It seems like we don't really need to take concurrency or timing issue into account here, but we do need to somehow use a queue to distribute the control.
Any suggestion?

jQuery 1.5 added deferred objects that handle this nicely. Simply call $.post
and attach any handlers you'd like after the call. Deferred objects even allow you to attach multiple success and error handlers.
Example:
$.post('status.ajax.php', {deviceId: id})
.done( function(msg) { ... } )
.fail( function(xhr, textStatus, errorThrown) {
alert(xhr.responseText);
});
Prior to jQuery 1.8, the function done
was called success
and fail
was called error
.
Try this
git fetch --all
git reset --hard origin/master
git pull origin master
It's work for me to force pull
the following is that the difference between iterator and listIterator
iterator :
boolean hasNext();
E next();
void remove();
listIterator:
boolean hasNext();
E next();
boolean hasPrevious();
E previous();
int nextIndex();
int previousIndex();
void remove();
void set(E e);
void add(E e);
You can use:
var tomorrow = new Date();
tomorrow.setDate(new Date().getDate()+1);
For example, since there are 30 days in April, the following code will output May 1:
var day = new Date('Apr 30, 2000');
console.log(day); // Apr 30 2000
var nextDay = new Date(day);
nextDay.setDate(day.getDate() + 1);
console.log(nextDay); // May 01 2000
See fiddle.

You can use hash.keys.include?(key)
irb(main):001:0> hash = {"pot" => 1, "tot" => 2, "not" => 3}
=> {"pot"=>1, "tot"=>2, "not"=>3}
irb(main):002:0> key = "not"
=> "not"
irb(main):003:0> hash.keys.include?(key)

You can use Mockito.isA()
for that:
import static org.mockito.Matchers.isA;
import static org.mockito.Mockito.verify;
verify(bar).doStuff(isA(Foo[].class));

Most programming languages aren't built on-top of existing programming languages. C++ is built on-top of C, and furthermore it's an object-oriented programming language built from a procedural programming language, and for that reason there are C++ expressions like extern "C"
which provide backwards compatibility with C.
Let's look at the following example:
#include <stdio.h>
// Two functions are defined with the same name
// but have different parameters
void printMe(int a) {
printf("int: %i\n", a);
}
void printMe(char a) {
printf("char: %c\n", a);
}
int main() {
printMe("a");
printMe(1);
return 0;
}
A C compiler will not compile the above example, because the same function printMe
is defined twice (even though they have different parameters int a
vs char a
).
gcc -o printMe printMe.c && ./printMe;
1 error. PrintMe is defined more than once.
A C++ compiler will compile the above example. It does not care that printMe
is defined twice.
g++ -o printMe printMe.c && ./printMe;
This is because a C++ compiler implicitly renames (mangles) functions based on their parameters. In C, this feature was not supported. However, when C++ was built over C, the language was designed to be object-oriented, and needed to support the ability to create different classes with methods (functions) of the same name, and to override methods (method overriding) based on different parameters.
extern "C"
says "don't mangle C function names"However, imagine we have a legacy C file named "parent.c" that include
s function names from other legacy C files, "parent.h", "child.h", etc. If the legacy "parent.c" file is run through a C++ compiler, then the function names will be mangled, and they will no longer match the function names specified in "parent.h", "child.h", etc - so the function names in those external files would also need to be mangled. Mangling function names across a complex C program, those with lots of dependencies, can lead to broken code; so it might be convenient to provide a keyword which can tell the C++ compiler not to mangle a function name.
The extern "C"
keyword tells a C++ compiler not to mangle (rename) C function names.
For example:
extern "C" void printMe(int a);
it is also possible to implement what you want using a single layer
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:bottom="-5dp"
android:right="-5dp"
android:top="-5dp">
<shape android:shape="rectangle" >
<solid android:color="@color/color_of_the_background" />
<stroke
android:width="5dp"
android:color="@color/color_of_the_border" />
</shape>
</item>
</layer-list>
this way only left border is visible but you can achieve any combination you want by playing with bottom
, left
, right
and top
attributes of the item
element
Passsing bitmap as parceable in bundle between activity is not a good idea because of size limitation of Parceable(1mb). You can store the bitmap in a file in internal storage and retrieve the stored bitmap in several activities. Here's some sample code.
To store bitmap in a file myImage in internal storage:
public String createImageFromBitmap(Bitmap bitmap) {
String fileName = "myImage";//no .png or .jpg needed
try {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
FileOutputStream fo = openFileOutput(fileName, Context.MODE_PRIVATE);
fo.write(bytes.toByteArray());
// remember close file output
fo.close();
} catch (Exception e) {
e.printStackTrace();
fileName = null;
}
return fileName;
}
Then in the next activity you can decode this file myImage to a bitmap using following code:
//here context can be anything like getActivity() for fragment, this or MainActivity.this
Bitmap bitmap = BitmapFactory.decodeStream(context.openFileInput("myImage"));
Note A lot of checking for null and scaling bitmap's is ommited.
A PivotTable might suit, though I am not quite certain of the layout of your data:
The bold numbers (one of each pair of duplicates) need not be shown as the field does not have to be subtotalled eg:
If I understood correctly you are trying to use a single query, i think you can just merge your date search toghter in WHERE
clauses
SELECT id
FROM events
WHERE start BETWEEN '2013-06-13' AND '2013-07-22'
AND end BETWEEN '2013-06-13' AND '2013-07-22'
or even more simply you can just use both column to set search time filter
SELECT id
FROM events
WHERE start >= '2013-07-22' AND end <= '2013-06-13'
select MY_SEQ_NAME.currval from DUAL;
Keep in mind that it only works if you ran select MY_SEQ_NAME.nextval from DUAL;
in the current sessions.
The os.exec*()
functions replace the current programm with the new one. When this programm ends so does your process. You probably want os.system()
.
There are two ways to download a file where the HTTP request requires that a header be set.
The credit for the first goes to @guest271314, and credit for the second goes to @dandavis.
The first method is to use the HTML5 File API to create a temporary local file, and the second is to use base64 encoding in conjunction with a data URI.
The solution I used in my project uses the base64 encoding approach for small files, or when the File API is not available, otherwise using the the File API approach.
Solution:
var id = 123;
var req = ic.ajax.raw({
type: 'GET',
url: '/api/dowloads/'+id,
beforeSend: function (request) {
request.setRequestHeader('token', 'token for '+id);
},
processData: false
});
var maxSizeForBase64 = 1048576; //1024 * 1024
req.then(
function resolve(result) {
var str = result.response;
var anchor = $('.vcard-hyperlink');
var windowUrl = window.URL || window.webkitURL;
if (str.length > maxSizeForBase64 && typeof windowUrl.createObjectURL === 'function') {
var blob = new Blob([result.response], { type: 'text/bin' });
var url = windowUrl.createObjectURL(blob);
anchor.prop('href', url);
anchor.prop('download', id+'.bin');
anchor.get(0).click();
windowUrl.revokeObjectURL(url);
}
else {
//use base64 encoding when less than set limit or file API is not available
anchor.attr({
href: 'data:text/plain;base64,'+FormatUtils.utf8toBase64(result.response),
download: id+'.bin',
});
anchor.get(0).click();
}
}.bind(this),
function reject(err) {
console.log(err);
}
);
Note that I'm not using a raw XMLHttpRequest
,
and instead using ic-ajax,
and should be quite similar to a jQuery.ajax
solution.
Note also that you should substitute text/bin
and .bin
with whatever corresponds to the file type being downloaded.
The implementation of FormatUtils.utf8toBase64
can be found here
A Y-Combinator is another name for a flux capacitor.
If you're coding for the kind of clarity that would be understood by someone who is just starting out with Perl, the traditional this construct says what it means, with a high degree of clarity and legibility:
$string = join ', ', @array;
print "$string\n";
This construct is documented in perldoc -f
join
.
However, I've always liked how simple $,
makes it. The special variable $"
is for interpolation, and the special variable $,
is for lists. Combine either one with dynamic scope-constraining 'local
' to avoid having ripple effects throughout the script:
use 5.012_002;
use strict;
use warnings;
my @array = qw/ 1 2 3 4 5 /;
{
local $" = ', ';
print "@array\n"; # Interpolation.
}
OR with $,:
use feature q(say);
use strict;
use warnings;
my @array = qw/ 1 2 3 4 5 /;
{
local $, = ', ';
say @array; # List
}
The special variables $,
and $"
are documented in perlvar. The local
keyword, and how it can be used to constrain the effects of altering a global punctuation variable's value is probably best described in perlsub.

The accepted answer of using npm-install-peers did not work, nor removing node_modules and rebuilding. The answer to run
npm install --save-dev @xxxxx/xxxxx@latest
for each one, with the xxxxx referring to the exact text in the peer warning, worked. I only had four warnings, if I had a dozen or more as in the question, it might be a good idea to script the commands.
Put the entire script into a template string, with {SERVERNAME} placeholders. Then edit the string using:
SET @SQL_SCRIPT = REPLACE(@TEMPLATE, '{SERVERNAME}', @DBNAME)
and then run it with
EXECUTE (@SQL_SCRIPT)
It's hard to believe that, in the course of three years, nobody noticed that my code doesn't work!
You can't EXEC
multiple batches. GO
is a batch separator, not a T-SQL statement. It's necessary to build three separate strings, and then to EXEC
each one after substitution.
I suppose one could do something "clever" by breaking the single template string into multiple rows by splitting on GO
; I've done that in ADO.NET code.
And where did I get the word "SERVERNAME" from?
Here's some code that I just tested (and which works):
DECLARE @DBNAME VARCHAR(255)
SET @DBNAME = 'TestDB'
DECLARE @CREATE_TEMPLATE VARCHAR(MAX)
DECLARE @COMPAT_TEMPLATE VARCHAR(MAX)
DECLARE @RECOVERY_TEMPLATE VARCHAR(MAX)
SET @CREATE_TEMPLATE = 'CREATE DATABASE {DBNAME}'
SET @COMPAT_TEMPLATE='ALTER DATABASE {DBNAME} SET COMPATIBILITY_LEVEL = 90'
SET @RECOVERY_TEMPLATE='ALTER DATABASE {DBNAME} SET RECOVERY SIMPLE'
DECLARE @SQL_SCRIPT VARCHAR(MAX)
SET @SQL_SCRIPT = REPLACE(@CREATE_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)
SET @SQL_SCRIPT = REPLACE(@COMPAT_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)
SET @SQL_SCRIPT = REPLACE(@RECOVERY_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)
Take a look at http://www.csharp-examples.net/download-files/ and msdn docs on webclient http://msdn.microsoft.com/en-us/library/system.net.webclient.aspx
My suggestion is try the synchronous download as its more straightforward. you might get ideas on whether webclient parameters are wrong or the file is in incorrect format while trying this.
Here is a code sample..
private void btnDownload_Click(object sender, EventArgs e)
{
string filepath = textBox1.Text;
WebClient webClient = new WebClient();
webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed);
webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged);
webClient.DownloadFileAsync(new Uri("http://mysite.com/myfile.txt"), filepath);
}
private void ProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
progressBar.Value = e.ProgressPercentage;
}
private void Completed(object sender, AsyncCompletedEventArgs e)
{
MessageBox.Show("Download completed!");
}
defined?
is great, but if you are in a Rails environment you can also use try
, especially in cases where you want to check a dynamic variable name:
foo = 1
my_foo = "foo"
my_bar = "bar"
try(:foo) # => 1
try(:bar) # => nil
try(my_foo) # => 1
try(my_bar) # => nil
In my case, I didnt have the Apple Root certificate. It can be found here:
I was looking for a solution to make the contents of a row behave like in a fixed width container, but with shrinking browser width make a minimal margin from the left (in my case: so that the row contents do not hide under a big logo with position: absolute
in left-top).
This is what worked for me:
HTML
<div class="parent-container">
<div class="child-container">
<h1>Some header</h1>
</div>
</div>
CSS
.parent-container {
padding-left: min(150px);
}
.child-container {
padding-left: calc( 50vw - 500px );
}
When I scale the browser window left and right, my h1
doesn't go to the left more than the 150px
, but goes right following the behavior of my next row's content set to display in a fixed container.
SQL Server Management Studio provides an Import/Export wizard tool which have an option to automatically create tables.
You can access it by right clicking on the Database in Object Explorer and selecting Tasks->Import Data...
From there wizard should be self-explanatory and easy to navigate. You choose your CSV as source, desired destination, configure columns and run the package.
If you need detailed guidance, there are plenty of guides online, here is a nice one: http://www.mssqltips.com/sqlservertutorial/203/simple-way-to-import-data-into-sql-server/

As far as i know this Pipeline Plugin is the "Engine" of the new Jenkinsfile mechanics, so im quite positive you could use this to locally test your scripts.
Im not sure if there is any additional steps needed when you copy it into a Jenkinsfile, however the syntax etc should be exactly the same.
Edit: Found the reference on the "engine", check this feature description, last paragraph, first entry.
Redirecting stderr

Scott Hanselman put together a great summary page with all of the various SQL downloads here https://www.hanselman.com/blog/DownloadSQLServerExpress.aspx.

There are two answers above up-to-now and they are both long (and tl;dr too short IMHO), so I write summary from my experience starting to use new java.time library (applicable as noted in other answers to Java version 8+). ISO 8601 sets standard way to write dates: YYYY-MM-DD
so the format of date-time is only as below (could be 0, 3, 6 or 9 digits for milliseconds) and no formatting string necessary:
import java.time.Instant;
public static void main(String[] args) {
String date="2010-10-02T12:23:23Z";
try {
Instant myDate = Instant.parse(date);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
I did not need it, but as getting year is in code from the question, then:
it is trickier, cannot be done from Instant
directly, can be done via Calendar
in way of questions Get integer value of the current year in Java and Converting java.time to Calendar but IMHO as format is fixed substring is more simple to use:
myDate.toString().substring(0,4);
Try placing the desired java directory in PATH before not needed java directories in your PATH.
Update! New & improved! Find plugin @ GitHub!
On another note, while that method is simple, I've created a jQuery plug (found at this jsFiddle, just copy and past code between comment lines) that makes changing the cursor on any element as simple as $("element").cursor("pointer")
.
But that's not all! Act now and you'll get the hand functions position
& ishover
for no extra charge! That's right, 2 very handy cursor functions ... FREE!
They work as simple as seen in the demo:
$("h3").cursor("isHover"); // if hovering over an h3 element, will return true,
// else false
// also handy as
$("h2, h3").cursor("isHover"); // unless your h3 is inside an h2, this will be
// false as it checks to see if cursor is hovered over both elements, not just the last!
// And to make this deal even sweeter - use the following to get a jQuery object
// of ALL elements the cursor is currently hovered over on demand!
$.cursor("isHover");
Also:
$.cursor("position"); // will return the current cursor position as { x: i, y: i }
// at anytime you call it!
Supplies are limited, so Act Now!
I've solved this issue by making use of the AddOrGetExisting method on the MemoryCache and the use of Lazy initialization.
Essentially, my code looks something like this:
static string GetCachedData(string key, DateTimeOffset offset)
{
Lazy<String> lazyObject = new Lazy<String>(() => SomeHeavyAndExpensiveCalculationThatReturnsAString());
var returnedLazyObject = MemoryCache.Default.AddOrGetExisting(key, lazyObject, offset);
if (returnedLazyObject == null)
return lazyObject.Value;
return ((Lazy<String>) returnedLazyObject).Value;
}
Worst case scenario here is that you create the same Lazy
object twice. But that is pretty trivial. The use of AddOrGetExisting
guarantees that you'll only ever get one instance of the Lazy
object, and so you're also guaranteed to only call the expensive initialization method once.
you could do so:
<button onclick="location.href='page'">
you could change the action attribute of the form on click the button:
<button class="float-left submit-button" onclick='myFun()'>Home</button>
<script>
myFun(){
$('form').attr('action','new path');
}
</script>
I was able to delete my Provisioning Profile from XCode 6 by using the Member Center online. I then just did a refresh/Sync in XCode 6 and it disappeared.
In the Apple Developer Member Center I had to do two things to make it happen:
Identifiers -> AP IDs
I had to first delete the old AP ID still using the old Provisioning Profile that I wanted to delete.
Provisioning Profiles
I then deleted the unwanted provisioning profile.In XCode:

Since you've already stashed your changes, all you need is this one-liner:
git stash branch <branchname> [<stash>]
From the docs (https://www.kernel.org/pub/software/scm/git/docs/git-stash.html):
Creates and checks out a new branch named <branchname> starting from the commit at which the <stash> was originally created, applies the changes recorded in <stash> to the new working tree and index. If that succeeds, and <stash> is a reference of the form stash@{<revision>}, it then drops the <stash>. When no <stash> is given, applies the latest one.
This is useful if the branch on which you ran git stash save has changed enough that git stash apply fails due to conflicts. Since the stash is applied on top of the commit that was HEAD at the time git stash was run, it restores the originally stashed state with no conflicts.

Right click on your /bat/ folder and click Create Shortcut.
bat - Shortcut
in the current directory.Shortcut to bat
.Right click on the shortcut you just created and click Properties.
Change Target (under the Shortcut tab on Windows 7) to the following:
%windir%\system32\cmd.exe /c start "" "%CD%\bat\bat\run.bat"
Make sure Start in is blank. That causes it to start in the current directory.
That's probably acceptable in the case of shortcutting to a .bat but if you want to change the icon, open the shortcut's properties again and click Change Icon... (again, under the Shortcut tab on Windows 7). At this point you can Browse... for an icon or bring up a list of default system icons by entering
%SystemRoot%\system32\SHELL32.dll
to the left of the Browse...
button and hitting Enter. This works on Windows 7 and Windows XP but the icons are different due to style updates (but are recognizably similar). Depending on the version of Windows the shortcut resides, the icon will will sometimes change accordingly.
More Info:
See Using the "start" command with parameters passed to the started program to better understand the empty double-quotes at the beginning of the first Target command.
For me, it was the StackOverFlow Exception because of recursive code.
In comparisons it makes a difference if a scalar is a number of a string. And it is not always decidable. I can report a case where perl retrieved a float in "scientific" notation and used that same a few lines below in a comparison:
use strict;
....
next unless $line =~ /and your result is:\s*(.*)/;
my $val = $1;
if ($val < 0.001) {
print "this is small\n";
}
And here $val
was not interpreted as numeric for e.g. "2e-77"
retrieved from $line
. Adding 0 (or 0.0 for good ole C programmers) helped.
I found a simple way around this in 2005. Here are my steps:
=IIF(Parameters!PageBreaks.Value="Y",Fields!DISP_PROJECT.Value,"")
Note: If the parameter =’Y’ then you will get the multiple sheets for each different value.
Otherwise the field is NULL for every group record (which causes only one page break at the end).Using 2.7:
from functools import partial
from random import randint
for roll in iter(partial(randint, 1, 8), 1):
print 'you rolled: {}'.format(roll)
print 'oops you rolled a 1!'
you rolled: 7
you rolled: 7
you rolled: 8
you rolled: 6
you rolled: 8
you rolled: 5
oops you rolled a 1!
Then change the "oops" print to a raise SystemExit
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
The thread is a bit old but i think this could probably save someone's time ...
I ran into the same problem as the original question, that the type is showed as Symfony\Component\Security\Core\User\User
It eventually turned out that i was logged in using an in memory user
my security.yml looks something like this
security:
providers:
chain_provider:
chain:
providers: [in_memory, fos_userbundle]
fos_userbundle:
id: fos_user.user_manager
in_memory:
memory:
users:
user: { password: userpass, roles: [ 'ROLE_USER' ] }
admin: { password: adminpass, roles: [ 'ROLE_ADMIN', 'ROLE_SONATA_ADMIN' ] }
the in_memory user type is always Symfony\Component\Security\Core\User\User if you want to use your own entity, log in using that provider's user.
Thanks, hj
This solution has the benefit of showing the URL of the linked-to page on hover, as most browsers do by default, instead of history.go(-1)
or similar:
<script>
document.write('<a href="' + document.referrer + '">Go Back</a>');
</script>
One possible option to implement such behavior is
PUT /groups/api/v1/groups/{group id}/status
{
"Status":"Activated"
}
And obviously, if someone need to deactivate it, PUT
will have Deactivated
status in JSON.
In case of necessity of mass activation/deactivation, PATCH
can step into the game (not for exact group, but for groups
resource:
PATCH /groups/api/v1/groups
{
{ “op”: “replace”, “path”: “/group1/status”, “value”: “Activated” },
{ “op”: “replace”, “path”: “/group7/status”, “value”: “Activated” },
{ “op”: “replace”, “path”: “/group9/status”, “value”: “Deactivated” }
}
In general this is idea as @Andrew Dobrowolski suggesting, but with slight changes in exact realization.
For performing Unmarshall using JAXB:
1) Convert given XML to XSD(by yourself or by online convertor),
2) Create a JAXB project in eclipse,
3) Create XSD file and paste that converted XSD content in it,
4) Right click on **XSD file--> Generate--> JAXB Classes-->follow the instructions(this will create all nessasary .java files in src, i.e., one package-info, object factory and pojo class),
5) Create another .java file in src to operate unmarshall operation, and run it.
Happy Coding !!
Take a look also at How do I sort unicode strings alphabetically in Python? where the discussion is about sorting rules given by the Unicode Collation Algorithm (http://www.unicode.org/reports/tr10/).
To reply to the comment
What? How else can ordering be defined other than left-to-right?
by S.Lott, there is a famous counter-example when sorting French language. It involves accents: indeed, one could say that, in French, letters are sorted left-to-right and accents right-to-left. Here is the counter-example: we have e < é and o < ô, so you would expect the words cote, coté, côte, côté to be sorted as cote < coté < côte < côté. Well, this is not what happens, in fact you have: cote < côte < coté < côté, i.e., if we remove "c" and "t", we get oe < ôe < oé < ôé, which is exactly right-to-left ordering.
And a last remark: you shouldn't be talking about left-to-right and right-to-left sorting but rather about forward and backward sorting.
Indeed there are languages written from right to left and if you think Arabic and Hebrew are sorted right-to-left you may be right from a graphical point of view, but you are wrong on the logical level!
Indeed, Unicode considers character strings encoded in logical order, and writing direction is a phenomenon occurring on the glyph level. In other words, even if in the word ???? the letter shin appears on the right of the lamed, logically it occurs before it. To sort this word one will first consider the shin, then the lamed, then the vav, then the mem, and this is forward ordering (although Hebrew is written right-to-left), while French accents are sorted backwards (although French is written left-to-right).
The lambda you pass to Where
can include any normal C# code, for example the &&
operator:
.Where(l => l.Title != string.Empty && l.InternalName != string.Empty)

Right after you append data to the view add this single line:
yourScrollview.fullScroll(ScrollView.FOCUS_DOWN);
For retrieving the screen resolution, you're going to want to use the System.Windows.Forms.Screen
class. The Screen.AllScreens
property can be used to access a collection of all of the displays on the system, or you can use the Screen.PrimaryScreen
property to access the primary display.
The Screen
class has a property called Bounds
, which you can use to determine the resolution of the current instance of the class. For example, to determine the resolution of the current screen:
Rectangle resolution = Screen.PrimaryScreen.Bounds;
For changing the resolution, things get a little more complicated. This article (or this one) provides a detailed implementation and explanation. Hope this helps.
From the dojo API documentation:

I've been searching for a simpler solution using only loops and if statements, and this is what I came up with. The program also works with negative integers and correctly rejects any mixed inputs that may contain both integers and other characters.
#include <stdio.h>
#include <stdlib.h> // Used for atoi() function
#include <string.h> // Used for strlen() function
#define TRUE 1
#define FALSE 0
int main(void)
{
char n[10]; // Limits characters to the equivalent of the 32 bits integers limit (10 digits)
int intTest;
printf("Give me an int: ");
do
{
scanf(" %s", n);
intTest = TRUE; // Sets the default for the integer test variable to TRUE
int i = 0, l = strlen(n);
if (n[0] == '-') // Tests for the negative sign to correctly handle negative integer values
i++;
while (i < l)
{
if (n[i] < '0' || n[i] > '9') // Tests the string characters for non-integer values
{
intTest = FALSE; // Changes intTest variable from TRUE to FALSE and breaks the loop early
break;
}
i++;
}
if (intTest == TRUE)
printf("%i\n", atoi(n)); // Converts the string to an integer and prints the integer value
else
printf("Retry: "); // Prints "Retry:" if tested FALSE
}
while (intTest == FALSE); // Continues to ask the user to input a valid integer value
return 0;
}

This is relatively new to C# which makes it easy for us to call the functions with respect to the null or non-null values in method chaining.
old way to achieve the same thing was:
var functionCaller = this.member;
if (functionCaller!= null)
functionCaller.someFunction(var someParam);
and now it has been made much easier with just:
member?.someFunction(var someParam);
I strongly recommend this doc page.
You did not specify the database engine in question; in Oracle, an option is to use tuples like this:
SELECT * FROM table WHERE (Col, 1) IN ((123,1),(123,1),(222,1),....)
This ugly hack only works in Oracle SQL, see https://asktom.oracle.com/pls/asktom/asktom.search?tag=limit-and-conversion-very-long-in-list-where-x-in#9538075800346844400
However, a much better option is to use stored procedures and pass the values as an array.
We were having similar issues with Font Awesome on a static "cookie-less" domain when reading fonts from the "cookie domain" (www.domain.tld) and this post was our hero. See here: How can I fix the 'Missing Cross-Origin Resource Sharing (CORS) Response Header' webfont issue?

You could try using a Polyfill. The following Polyfill was published in 2019 and did the trick for me. It assigns the Promise function to the window object.
used like: window.Promise
https://www.npmjs.com/package/promise-polyfill
If you want more information on Polyfills check out the following MDN web doc https://developer.mozilla.org/en-US/docs/Glossary/Polyfill
Do you want a better way to pass the arguments or just a way to stop pylint
from giving you a hard time? If the latter, I seem to recall that you could stop the nagging by putting pylint
-controlling comments in your code along the lines of:
#pylint: disable=R0913
or, better:
#pylint: disable=too-many-arguments
remembering to turn them back on as soon as practicable.
In my opinion, there's nothing inherently wrong with passing a lot of arguments and solutions advocating wrapping them all up in some container argument don't really solve any problems, other than stopping pylint
from nagging you :-).
If you need to pass twenty arguments, then pass them. It may be that this is required because your function is doing too much and a re-factoring could assist there, and that's something you should look at. But it's not a decision we can really make unless we see what the 'real' code is.
Sometimes it doesnt fire when the script has some syntax error, make sure the script and javascript syntax is correct.
Easiest way I find is to:
Right click project
Debug as -> Maven build ...
In the goals field put -Dmaven.surefire.debug test
In the parameters put a new parameter called forkCount with a value of 0 (previously was forkMode=never but it is deprecated and doesn't work anymore)
Set your breakpoints down and run this configuration and it should hit the breakpoint.
Another drawback of const
in C is that you can't use the value in initializing another const
.
static int const NUMBER_OF_FINGERS_PER_HAND = 5;
static int const NUMBER_OF_HANDS = 2;
// initializer element is not constant, this does not work.
static int const NUMBER_OF_FINGERS = NUMBER_OF_FINGERS_PER_HAND
* NUMBER_OF_HANDS;
Even this does not work with a const since the compiler does not see it as a constant:
static uint8_t const ARRAY_SIZE = 16;
static int8_t const lookup_table[ARRAY_SIZE] = {
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16}; // ARRAY_SIZE not a constant!
I'd be happy to use typed const
in these cases, otherwise...
In rails 2.3.x application you can start your server by following command:
ruby script/server
In rails 3.x, you need to go for:
rails s
Here's another, maybe simpler implementation of string IndexOfNth()
with strings implementation.
Here's the string
match version:
public static int IndexOfNth(this string source, string matchString,
int charInstance,
StringComparison stringComparison = StringComparison.CurrentCulture)
{
if (string.IsNullOrEmpty(source))
return -1;
int lastPos = 0;
int count = 0;
while (count < charInstance )
{
var len = source.Length - lastPos;
lastPos = source.IndexOf(matchString, lastPos,len,stringComparison);
if (lastPos == -1)
break;
count++;
if (count == charInstance)
return lastPos;
lastPos += matchString.Length;
}
return -1;
}
and the char
match version:
public static int IndexOfNth(string source, char matchChar, int charInstance)
{
if (string.IsNullOrEmpty(source))
return -1;
if (charInstance < 1)
return -1;
int count = 0;
for (int i = 0; i < source.Length; i++)
{
if (source[i] == matchChar)
{
count++;
if (count == charInstance)
return i;
}
}
return -1;
}
I think for such a low level implementation you'd want to stay away from using LINQ, RegEx or recursion to reduce overhead.
For Ubuntu 14.04 and 16.04, you can apply following commands
First, check MySQL service is running or not using
sudo service mysql status
Now you can see you show a message like this: mysql stop/waiting.
Now apply command: sudo service mysql restart!
Now you can see you show a message like this: mysql start/running, process 8313.
Now go to the browser and logged in as root(username) and root(password) and you will be logged in successfully
For getting the list of ip addresses associated, you can use netstat command
netstat -rn
This gives a long list of ip addresses and it is not easy to find the required field. The sample result is as following:
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 192.168.195.1 UGSc 17 0 en2
127 127.0.0.1 UCS 0 0 lo0
127.0.0.1 127.0.0.1 UH 1 254107 lo0
169.254 link#7 UCS 0 0 en2
192.168.195 link#7 UCS 3 0 en2
192.168.195.1 0:27:22:67:35:ee UHLWIi 22 397 en2 1193
192.168.195.5 127.0.0.1 UHS 0 0 lo0
More result is truncated.......
The ip address of gateway is in the first line; one with default at its first column.
To display only the selected lines of result, we can use grep command along with netstat
netstat -rn | grep 'default'
This command filters and displays those lines of result having default. In this case, you can see result like following:
default 192.168.195.1 UGSc 14 0 en2
If you are interested in finding only the ip address of gateway and nothing else you can further filter the result using awk. The awk command matches pattern in the input result and displays the output. This can be useful when you are using your result directly in some program or batch job.
netstat -rn | grep 'default' | awk '{print $2}'
The awk command tells to match and print the second column of the result in the text. The final result thus looks like this:
192.168.195.1
In this case, netstat displays all result, grep only selects the line with 'default' in it, and awk further matches the pattern to display the second column in the text.
You can similarly use route -n get default command to get the required result. The full command is
route -n get default | grep 'gateway' | awk '{print $2}'
These commands work well in linux as well as unix systems and MAC OS.
You might need a GLOBAL TEMPORARY TABLE.
In Oracle these are created once and then when invoked the data is private to your session.
Try something like this...
CREATE GLOBAL TEMPORARY TABLE temp_number
( number_column NUMBER( 10, 0 )
)
ON COMMIT DELETE ROWS;
BEGIN
INSERT INTO temp_number
( number_column )
( select distinct sgbstdn_pidm
from sgbstdn
where sgbstdn_majr_code_1 = 'HS04'
and sgbstdn_program_1 = 'HSCOMPH'
);
FOR pidms_rec IN ( SELECT number_column FROM temp_number )
LOOP
-- Do something here
NULL;
END LOOP;
END;

If you are trying to prevent a request from running too long, then setting a timeout in Tomcat will not help you. As Chris says, you can set the global timeout value for Tomcat. But, from The Apache Tomcat Connector - Generic HowTo Timeouts, see the Reply Timeout section:
JK can also use a timeout on request replies. This timeout does not measure the full processing time of the response. Instead it controls, how much time between consecutive response packets is allowed.
In most cases, this is what one actually wants. Consider for example long running downloads. You would not be able to set an effective global reply timeout, because downloads could last for many minutes. Most applications though have limited processing time before starting to return the response. For those applications you could set an explicit reply timeout. Applications that do not harmonise with reply timeouts are batch type applications, data warehouse and reporting applications which are expected to observe long processing times.
If JK aborts waiting for a response, because a reply timeout fired, there is no way to stop processing on the backend. Although you free processing resources in your web server, the request will continue to run on the backend - without any way to send back a result once the reply timeout fired.
So Tomcat will detect that the servlet has not responded within the timeout and will send back a response to the user, but will not stop the thread running. I don't think you can achieve what you want to do.
A closure is where an inner function has access to variables in its outer function. That's probably the simplest one-line explanation you can get for closures.
This will grab records with strings (in the fieldName column) that are 10 characters long:
select * from table where length(fieldName)=10
This warning comes because your dataframe x
is a copy of a slice. This is not easy to know why, but it has something to do with how you have come to the current state of it.
You can either create a proper dataframe
out of x by doing
x = x.copy()
This will remove the warning, but it is not the proper way
You should be using the DataFrame.loc
method, as the warning suggests, like this:
x.loc[:,'Mass32s'] = pandas.rolling_mean(x.Mass32, 5).shift(-2)
file:///
is a URI (Uniform Resource Identifier) that simply distinguishes from the standard URI that we all know of too well - http://
.
It does imply an absolute path name pointing to the root directory in any environment, but in the context of Android, it's a convention to tell the Android run-time to say "Here, the directory www
has a file called index.html
located in the assets
folder in the root of the project".
That is how assets are loaded at runtime, for example, a WebView
widget would know exactly where to load the embedded resource file by specifying the file:///
URI.
Consider the code example:
WebView webViewer = (WebView) findViewById(R.id.webViewer);
webView.loadUrl("file:///android_asset/www/index.html");
A very easy mistake to make here is this, some would infer it to as file:///android_assets
, notice the plural of assets in the URI and wonder why the embedded resource is not working!
I can see at least three options:
1.
df[:10]
2. Using head
df.head(10)
For negative values of n, this function returns all rows except the last n rows, equivalent to
df[:-n]
[Source].
3. Using iloc
df.iloc[:10]
That's about it. There is no magic built-in function...
$_SERVER['REQUEST_URI']
doesn't work on IIS, but I did find this: http://neosmart.net/blog/2006/100-apache-compliant-request_uri-for-iis-and-windows/ which sounds promising.
You need this:
window.onload = function(){
var elCheckBox=document.getElementById("cbxTodos");
elCheckBox.onchange =function (){
alert("como ves");
}
};
I also developed my own password generator, with random length (between 16 and 40 by default), strong passwords, maybe it could help.
function randomChar(string) {
return string[Math.floor(Math.random() * string.length)];
}
// you should use another random function, like the lodash's one.
function random(min = 0, max = 1) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}
// you could use any shuffle function, the lodash's one, or the following https://stackoverflow.com/a/6274381/6708504
function shuffle(a) {
for (let i = a.length - 1; i > 0; i--) {
const j = Math.floor(Math.random() * (i + 1));
[a[i], a[j]] = [a[j], a[i]];
}
return a;
}
function generatePassword() {
const symbols = '§±!@#$%^&*()-_=+[]{}\\|?/<>~';
const numbers = '0123456789';
const lowercaseLetters = 'abcdefghijklmnopqrstuvwxyz';
const uppercaseLetters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
const minCharsGroup = 4;
const maxCharsGroup = 10;
const randomSymbols = [...Array(random(minCharsGroup, maxCharsGroup))].map(() => randomChar(symbols));
const randomNumbers = [...Array(random(minCharsGroup, maxCharsGroup))].map(() => randomChar(numbers));
const randomUppercasesLetters = [...Array(random(minCharsGroup, maxCharsGroup))].map(() => randomChar(uppercaseLetters));
const randomLowercasesLetters = [...Array(random(minCharsGroup, maxCharsGroup))].map(() => randomChar(lowercaseLetters));
const chars = [...randomSymbols, ...randomNumbers, ...randomUppercasesLetters, ...randomLowercasesLetters];
return shuffle(chars).join('');
}
The proper way to do with would be to use the v-el
directive to give it a reference. Then you can do this.$$[reference]
.
In Vue 2 refs are used for both elements and components: http://vuejs.org/guide/migration.html#v-el-and-v-ref-replaced
You can use the below code:
-
mysqldump -d <database name> <tablename> > <filename.sql>
-
mysqldump <database name> <tablename> > <filename.sql>
Hope it will help.
Another way to read multiple inputs within a loop which can handle an input with spaces:
package main
import (
"fmt"
"bufio"
"os"
)
func main() {
scanner := bufio.NewScanner(os.Stdin)
var text string
for text != "q" { // break the loop if text == "q"
fmt.Print("Enter your text: ")
scanner.Scan()
text = scanner.Text()
if text != "q" {
fmt.Println("Your text was: ", text)
}
}
}
Output:
Enter your text: Hello world!
Your text was: Hello world!
Enter your text: Go is awesome!
Your text was: Go is awesome!
Enter your text: q
How about:
function filterObj(keys, obj) {
const newObj = {};
for (let key in obj) {
if (keys.includes(key)) {
newObj[key] = obj[key];
}
}
return newObj;
}
Or...
function filterObj(keys, obj) {
const newObj = {};
Object.keys(obj).forEach(key => {
if (keys.includes(key)) {
newObj[key] = obj[key];
}
});
return newObj;
}
NSData *data = [strChangetoJSON dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:&error];
For example you have a NSString
with special characters in NSString
strChangetoJSON.
Then you can convert that string to JSON response using above code.
