For Spring 5.2+ this works for me:
@PostMapping("/foo")
ResponseEntity<Void> foo(@PathVariable UUID fooId) {
return fooService.findExam(fooId)
.map(uri -> ResponseEntity.noContent().<Void>build())
.orElse(ResponseEntity.notFound().build());
}
CASE WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%'
THEN 'BP Medication' ELSE '' END AS [BP Medication]
The leading ', '
and trailing ','
are added so that you can handle the match regardless of where it is in the string (first entry, last entry, or anywhere in between).
That said, why are you storing data you want to search on as a comma-separated string? This violates all kinds of forms and best practices. You should consider normalizing your schema.
In addition: don't use 'single quotes'
as identifier delimiters; this syntax is deprecated. Use [square brackets]
(preferred) or "double quotes"
if you must. See "string literals as column aliases" here: http://msdn.microsoft.com/en-us/library/bb510662%28SQL.100%29.aspx
EDIT If you have multiple values, you can do this (you can't short-hand this with the other CASE
syntax variant or by using something like IN()
):
CASE
WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%'
WHEN ', ' + dbo.Table.Column +',' LIKE '%, amlodipine,%'
THEN 'BP Medication' ELSE '' END AS [BP Medication]
If you have more values, it might be worthwhile to use a split function, e.g.
USE tempdb;
GO
CREATE FUNCTION dbo.SplitStrings(@List NVARCHAR(MAX))
RETURNS TABLE
AS
RETURN ( SELECT DISTINCT Item FROM
( SELECT Item = x.i.value('(./text())[1]', 'nvarchar(max)')
FROM ( SELECT [XML] = CONVERT(XML, '<i>'
+ REPLACE(@List,',', '</i><i>') + '</i>').query('.')
) AS a CROSS APPLY [XML].nodes('i') AS x(i) ) AS y
WHERE Item IS NOT NULL
);
GO
CREATE TABLE dbo.[Table](ID INT, [Column] VARCHAR(255));
GO
INSERT dbo.[Table] VALUES
(1,'lactulose, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(2,'lactulite, Lasix (furosemide), lactulose, propranolol, rabeprazole, sertraline,'),
(3,'lactulite, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(4,'lactulite, Lasix (furosemide), lactulose, amlodipine, rabeprazole, sertraline,');
SELECT t.ID
FROM dbo.[Table] AS t
INNER JOIN dbo.SplitStrings('lactulose,amlodipine') AS s
ON ', ' + t.[Column] + ',' LIKE '%, ' + s.Item + ',%'
GROUP BY t.ID;
GO
Results:

The % does two things, depending on its arguments. In this case, it acts as the modulo operator, meaning when its arguments are numbers, it divides the first by the second and returns the remainder. 34 % 10 == 4
since 34 divided by 10 is three, with a remainder of four.
If the first argument is a string, it formats it using the second argument. This is a bit involved, so I will refer to the documentation, but just as an example:
>>> "foo %d bar" % 5
'foo 5 bar'
However, the string formatting behavior is supplemented as of Python 3.1 in favor of the string.format()
mechanism:
The formatting operations described here exhibit a variety of quirks that lead to a number of common errors (such as failing to display tuples and dictionaries correctly). Using the newer
str.format()
interface helps avoid these errors, and also provides a generally more powerful, flexible and extensible approach to formatting text.
And thankfully, almost all of the new features are also available from python 2.6 onwards.
Your quotes only need to surround the value part of the attribute-equals selector, [attr='val']
, like this:
$('a#check_var').click(function() {
alert($("input:radio[name='r']:checked").val()+ ' '+
$("input:radio[name='s']:checked").val());
});?
Instead of comparing the dates directly, compare the getTime() value of the date. The getTime() function returns the number of milliseconds since Jan 1, 1970 as an integer-- should be trivial to determine if one integer falls between two other integers.
Something like
if((check.getTime() <= to.getTime() && check.getTime() >= from.getTime())) alert("date contained");
Simply issuing rm CMakeCache.txt
works for me too.
Check again. Use debugger if must. My guess is that for some item in userResponseDetails this query finds no elements:
.Where(y => y.ResponseId.Equals(item.ResponseId))
so you can't call
.First()
on it. Maybe try
.FirstOrDefault()
if it solves the issue.
Do NOT return NULL value! This is purely so that you can see and diagnose where problem is. Handle these cases properly.
I would like introduce simple script to parse RSS:
$i = 0; // counter
$url = "http://www.banki.ru/xml/news.rss"; // url to parse
$rss = simplexml_load_file($url); // XML parser
// RSS items loop
print '<h2><img style="vertical-align: middle;" src="'.$rss->channel->image->url.'" /> '.$rss->channel->title.'</h2>'; // channel title + img with src
foreach($rss->channel->item as $item) {
if ($i < 10) { // parse only 10 items
print '<a href="'.$item->link.'">'.$item->title.'</a><br />';
}
$i++;
}
I also had the same problem and it tooks me several hours to figured out.
I just changed 'config' to 'cookie'
$cfg['Servers'][$i]['auth_type'] = 'config';
Try adding multiDexEnabled true
to your app build.gradle
file.
defaultConfig {
multiDexEnabled true
}
Answering your question as the examples also given previously:
items = []
items.append("apple")
items.append("orange")
items.append("banana")
print items.__len__()
Element needs to be a variant, so you can't declare it as a string. Your function should accept a variant if it is a string though as long as you pass it ByVal.
Public Sub example()
Dim sArray(4) As string
Dim element As variant
For Each element In sArray
do_something (element)
Next element
End Sub
Sub do_something(ByVal e As String)
End Sub
The other option is to convert the variant to a string before passing it.
do_something CStr(element)
Just add UILongPressGestureRecognizer to the given prototype cell in storyboard, then pull the gesture to the viewController's .m file to create an action method. I made it as I said.
An easy solution is x = [None]*length
, but note that it initializes all list elements to None
. If the size is really fixed, you can do x=[None,None,None,None,None]
as well. But strictly speaking, you won't get undefined elements either way because this plague doesn't exist in Python.
You should follow the instructions provided in the documentation, using the web.config
.
<aspNetCore processPath="dotnet"
arguments=".\MyApp.dll"
stdoutLogEnabled="false"
stdoutLogFile="\\?\%home%\LogFiles\aspnetcore-stdout">
<environmentVariables>
<environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Production" />
<environmentVariable name="CONFIG_DIR" value="f:\application_config" />
</environmentVariables>
</aspNetCore>
Note that you can also set other environment variables as well.
The ASP.NET Core Module allows you specify environment variables for the process specified in the processPath attribute by specifying them in one or more environmentVariable child elements of an environmentVariables collection element under the aspNetCore element. Environment variables set in this section take precedence over system environment variables for the process.
Duration timeLeft = Duration.ofMillis(3600000);
String hhmmss = String.format("%02d:%02d:%02d",
timeLeft.toHours(), timeLeft.toMinutesPart(), timeLeft.toSecondsPart());
System.out.println(hhmmss);
This prints:
01:00:00
You are doing right in letting library methods do the conversions involved for you. java.time
, the modern Java date and time API, or more precisely, its Duration
class does it more elegantly and in a less error-prone way than TimeUnit
.
The toMinutesPart
and toSecondsPart
methods I used were introduced in Java 9.
long hours = timeLeft.toHours();
timeLeft = timeLeft.minusHours(hours);
long minutes = timeLeft.toMinutes();
timeLeft = timeLeft.minusMinutes(minutes);
long seconds = timeLeft.toSeconds();
String hhmmss = String.format("%02d:%02d:%02d", hours, minutes, seconds);
System.out.println(hhmmss);
The output is the same as above.
java.time
comes built-in.org.threeten.bp
with subpackages.java.time
.java.time
was first described.java.time
to Java 6 and 7 (ThreeTen for JSR-310).I think the easiest way is to make a 'string' extension method (based on what user Richard have suggested):
using System;
using System.Text.RegularExpressions;
public static class StringHelpers
{
public static string StripHTML(this string HTMLText)
{
var reg = new Regex("<[^>]+>", RegexOptions.IgnoreCase);
return reg.Replace(HTMLText, "");
}
}
Then just use this extension method on any 'string' variable in your program:
var yourHtmlString = "<div class=\"someclass\"><h2>yourHtmlText</h2></span>";
var yourTextString = yourHtmlString.StripHTML();
I use this extension method to convert html formated comments to plain text so it will be displayed correctly on a crystal report, and it works perfect!
Open a command prompt window. If you have a default instance of SQL Server already running, run the following command on the command prompt to stop the SQL Server service:
net stop mssqlserver
Now go to the directory where SQL server is installed. The directory can for instance be one of these:
C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Binn
C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Binn
Figure out your MSSQL directory and CD
into it as such:
CD C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Binn
Now run the following command to start SQL Server in single user mode. As
SQLCMD
is being specified, only one SQLCMD
connection can be made (from another command prompt window).
sqlservr -m"SQLCMD"
Now, open another command prompt window as the same user as the one that started SQL Server in single user mode above, and in it, run:
sqlcmd
And press enter. Now you can execute SQL statements against the SQL Server instance running in single user mode:
create login [<<DOMAIN\USERNAME>>] from windows;
-- For older versions of SQL Server:
EXEC sys.sp_addsrvrolemember @loginame = N'<<DOMAIN\USERNAME>>', @rolename = N'sysadmin';
-- For newer versions of SQL Server:
ALTER SERVER ROLE [sysadmin] ADD MEMBER [<<DOMAIN\USERNAME>>];
GO
UPDATED
Do not forget a semicolon after ALTER SERVER ROLE [sysadmin] ADD MEMBER [<<DOMAIN\USERNAME>>];
and do not add extra semicolon after GO
or the command never executes.
The below query helps to get the row number in oracle,
SELECT ROWNUM AS SNO,ID,NAME,EMAIL,BRANCH FROM student WHERE NAME LIKE '%ram%';
A built-in Map type is now available in JavaScript. It can be used instead of simply using Object. It is supported by current versions of all major browsers.
Maps do not support the [subscript]
notation used by Objects. That syntax implicitly casts the subscript
value to a primitive string or symbol. Maps support any values as keys, so you must use the methods .get(key)
, .set(key, value)
and .has(key)
.
var m = new Map();_x000D_
var key1 = 'key1';_x000D_
var key2 = {};_x000D_
var key3 = {};_x000D_
_x000D_
m.set(key1, 'value1');_x000D_
m.set(key2, 'value2');_x000D_
_x000D_
console.assert(m.has(key2), "m should contain key2.");_x000D_
console.assert(!m.has(key3), "m should not contain key3.");
_x000D_
Objects only supports primitive strings and symbols as keys, because the values are stored as properties. If you were using Object, it wouldn't be able to to distinguish key2
and key3
because their string representations would be the same:
var o = new Object();_x000D_
var key1 = 'key1';_x000D_
var key2 = {};_x000D_
var key3 = {};_x000D_
_x000D_
o[key1] = 'value1';_x000D_
o[key2] = 'value2';_x000D_
_x000D_
console.assert(o.hasOwnProperty(key2), "o should contain key2.");_x000D_
console.assert(!o.hasOwnProperty(key3), "o should not contain key3."); // Fails!
_x000D_

// all corners
outline.setRoundRect(left, top, right, bottom, cornerRadius.toFloat())
/* top corners

How about:
import re
s = "alpha.Customer[cus_Y4o9qMEZAugtnW] ..."
m = re.search(r"\[([A-Za-z0-9_]+)\]", s)
print m.group(1)
For me this prints:
cus_Y4o9qMEZAugtnW
Note that the call to re.search(...)
finds the first match to the regular expression, so it doesn't find the [card]
unless you repeat the search a second time.
Edit: The regular expression here is a python raw string literal, which basically means the backslashes are not treated as special characters and are passed through to the re.search()
method unchanged. The parts of the regular expression are:
\[
matches a literal [
character(
begins a new group[A-Za-z0-9_]
is a character set matching any letter (capital or lower case), digit or underscore+
matches the preceding element (the character set) one or more times.)
ends the group\]
matches a literal ]
characterEdit: As D K has pointed out, the regular expression could be simplified to:
m = re.search(r"\[(\w+)\]", s)
since the \w
is a special sequence which means the same thing as [a-zA-Z0-9_]
depending on the re.LOCALE
and re.UNICODE
settings.
You can use relative path to mount the volume to container:
docker run -v `pwd`/certs:/container/path/to/certs ...
Note the back tick on the pwd
which give you the present working directory. It assumes you have the certs
folder in current directory that the docker run
is executed. Kinda great for local development and keep the certs folder visible to your project.
Well, it'd still be convenient (syntactically) if we could declare usual values inside the if's condition. So, here's a trick: you can make the compiler think there is an assignment of Optional.some(T)
to a value like so:
if let i = "abc".firstIndex(of: "a"),
let i_int = .some(i.utf16Offset(in: "abc")),
i_int < 1 {
// Code
}
As stated in this blog post it seems possible to use mod_security to implement a rate limit per second.

git remote manpage is pretty straightforward:
Use
Older (backwards-compatible) syntax:
$ git remote rm upstream
Newer syntax for newer git versions: (* see below)
$ git remote remove upstream
Then do:
$ git remote add upstream https://github.com/Foo/repos.git
or just update the URL directly:
$ git remote set-url upstream https://github.com/Foo/repos.git
or if you are comfortable with it, just update the .git/config directly - you can probably figure out what you need to change (left as exercise for the reader).
...
[remote "upstream"]
fetch = +refs/heads/*:refs/remotes/upstream/*
url = https://github.com/foo/repos.git
...

* Regarding 'git remote rm' vs 'git remote remove' - this changed around git 1.7.10.3 / 1.7.12 2 - see
Log message
remote: prefer subcommand name 'remove' to 'rm'
All remote subcommands are spelled out words except 'rm'. 'rm', being a
popular UNIX command name, may mislead users that there are also 'ls' or
'mv'. Use 'remove' to fit with the rest of subcommands.
'rm' is still supported and used in the test suite. It's just not
widely advertised.
My approach is to scan the string and let the pointers point to every character after the deliminators(and the first character), at the same time assign the appearances of deliminator in string to '\0'.
First make a copy of original string(since it's constant), then get the number of splits by scan it pass it to pointer parameter len. After that, point the first result pointer to the copy string pointer, then scan the copy string: once encounter a deliminator, assign it to '\0' thus the previous result string is terminated, and point the next result string pointer to the next character pointer.
char** split(char* a_str, const char a_delim, int* len){
char* s = (char*)malloc(sizeof(char) * strlen(a_str));
strcpy(s, a_str);
char* tmp = a_str;
int count = 0;
while (*tmp != '\0'){
if (*tmp == a_delim) count += 1;
tmp += 1;
}
*len = count;
char** results = (char**)malloc(count * sizeof(char*));
results[0] = s;
int i = 1;
while (*s!='\0'){
if (*s == a_delim){
*s = '\0';
s += 1;
results[i++] = s;
}
else s += 1;
}
return results;
}
Just ask it for the objectForKey:@"b"
. If it returns nil
, no object is set at that key.
if ([xyz objectForKey:@"b"]) {
NSLog(@"There's an object set for key @\"b\"!");
} else {
NSLog(@"No object set for key @\"b\"");
}
Edit: As to your edited second question, it's simply NSUInteger mCount = [xyz count];
. Both of these answers are documented well and easily found in the NSDictionary class reference ([1] [2]).
I usually use the overflow: auto
trick; although that's not, strictly speaking, the intended use for overflow, it is kinda related - enough to make it easy to remember, certainly. The meaning of float: left
itself has been extended for various uses more significantly than overflow is in this example, IMO.
I've found a solution that seems perfect to me, but it needs extra <div>
tags.
It turns out that it is not necessary to use <table>
tag to align as in a table, it suffices to use display:table-row;
and display:table-cell;
styles:
<style type="text/css">
dl > div {
display: table-row;
}
dl > div > dt {
display: table-cell;
background: #ff0;
}
dl > div > dd {
display: table-cell;
padding-left: 1em;
background: #0ff;
}
</style>
<dl>
<div>
<dt>Mercury</dt>
<dd>Mercury (0.4 AU from the Sun) is the closest planet to the Sun and the smallest planet.</dd>
</div>
<div>
<dt>Venus</dt>
<dd>Venus (0.7 AU) is close in size to Earth, (0.815 Earth masses) and like Earth, has a thick silicate mantle around an iron core.</dd>
</div>
<div>
<dt>Earth</dt>
<dd>Earth (1 AU) is the largest and densest of the inner planets, the only one known to have current geological activity.</dd>
</div>
</dl>
I know this question is specific to sql server, but I'm using postgresql and came across this question, so for anybody else in a similar situation, there is the split_part(string text, delimiter text, field int)
function.
You need to move type parameter to the method level to indicate that you have a generic method rather than generic class:
public class ArrayUtils {
public static <T> E[] appendToArray(E[] array, E item) {
E[] result = (E[])new Object[array.length+1];
result[array.length] = item;
return result;
}
}
Try:
if not "asdf" == "fdas" echo asdf
That works for me on Windows XP (I get the same error as you for the code you posted).
It works fine with the object literal notation:
var map = { key : { "aaa", "rrr" },
key2: { "bbb", "ppp" } // trailing comma leads to syntax error in IE!
}
Btw, the common way to instantiate arrays
var array = [];
// directly with values:
var array = [ "val1", "val2", 3 /*numbers may be unquoted*/, 5, "val5" ];
and objects
var object = {};
Also you can do either:
obj.property // this is prefered but you can also do
obj["property"] // this is the way to go when you have the keyname stored in a var
var key = "property";
obj[key] // is the same like obj.property
Obligatory Twisted example:
twistd -n ftp
And probably useful:
twistd ftp --help
Usage: twistd [options] ftp [options].
WARNING: This FTP server is probably INSECURE do not use it.
Options:
-p, --port= set the port number [default: 2121]
-r, --root= define the root of the ftp-site. [default:
/usr/local/ftp]
--userAnonymous= Name of the anonymous user. [default: anonymous]
--password-file= username:password-style credentials database
--version
--help Display this help and exit.
Use this inside of query, no need to create extra variables.
CASE WHEN CreatedDate = '19000101' THEN '' WHEN CreatedDate =
'18000101' THEN '' ELSE CONVERT(CHAR(10), CreatedDate, 120) + ' ' +
CONVERT(CHAR(8), CreatedDate, 108) END as 'Created Date'
Works like a charm.
You can do:
string[] a = { String.Empty };
Note: OP meant not having to specify a size, not make an array sizeless
Removing an entire commit
git rebase -p --onto SHA^ SHA
Obviously replace "SHA" with the reference you want to get rid of. The "^" in that command is literal.

You can use your own customize class based on the concept, here the code snippet which you can use to do the stuff
/*
* Stack implementation in JavaScript
*/
function Stack() {
this.top = null;
this.count = 0;
this.getCount = function() {
return this.count;
}
this.getTop = function() {
return this.top;
}
this.push = function(data) {
var node = {

next: null
}
node.next = this.top;
this.top = node;
this.count++;
}
this.peek = function() {

Addition to @MarkR answer - one thing to note would be that many PHP frameworks with ORMs would not recognize or use advanced DB setup (foreign keys, cascading delete, unique constraints), and this may result in unexpected behaviour.
For example if you delete a record using ORM, and your DELETE CASCADE
will delete records in related tables, ORM's attempt to delete these related records (often automatic) will result in error.
I think this may help you solve your issue.
Imagine you have a dictionary like this:
dic0 = {0:"CL1", 1:"CL2", 2:"CL3"}
And you want to change values by this one:
dic0to1 = {"CL1":"Unknown1", "CL2":"Unknown2", "CL3":"Unknown3"}
You can use code bellow to change values of dic0
properly respected to dic0t01
without worrying yourself about indexes in dictionary:
for x, y in dic0.items():
dic0[x] = dic0to1[y]
Now you have:
>>> dic0
{0: 'Unknown1', 1: 'Unknown2', 2: 'Unknown3'}
you can use lambda inside map in python. wrote a gray codes generator. https://github.com/rdm750/rdm750.github.io/blob/master/python/gray_code_generator.py # your code goes here ''' the n-1 bit code, with 0 prepended to each word, followed by the n-1 bit code in reverse order, with 1 prepended to each word.

The easiest and fastest way to convert a Pandas dataframe into a png image using Anaconda Spyder IDE- just double-click on the dataframe in variable explorer, and the IDE table will appear, nicely packaged with automatic formatting and color scheme. Just use a snipping tool to capture the table for use in your reports, saved as a png:
This saves me lots of time, and is still elegant and professional.

Everyone seems to be ignoring the "enum type" portion of your question.
While there is no canonical source for HTTP Status Codes there is an simple way to add any missing Status constants you need to those provided by javax.ws.rs.core.Response.Status
without adding any additional dependencies to your project.
javax.ws.rs.core.Response.Status
is just one implementation of the javax.ws.rs.core.Response.StatusType
interface. You simply need to create your own implementation enum with definitions for the Status Codes that you want.
Core libraries like Javax, Jersey, etc. are written to the interface StatusType
not the implementation Status
(or they certainly should be). Since your new Status enum implements StatusType
it can be used anyplace you would use a javax.ws.rs.core.Response.Status
constant.
Just remember that your own code should also be written to the StatusType
interface. This will enable you to use both your own Status Codes along side the "standard" ones.
Here's a gist with a simple implementation with constants defined for the "Informational 1xx" Status Codes: https://gist.github.com/avendasora/a5ed9acf6b1ee709a14a
More a comment than an answer - but I cannot add comments yet: Thanks for your help, the count was the easy part. Just for others that might come here. I hope that it will save you some time.
It took me a while to get the attributes from the rows and to understand how to access them from the data() Object (that the data() is an Array and the Attributes can be read by adding them with a dot and not with brackets:
$('#button').click( function () {
for (var i = 0; i < table.rows('.selected').data().length; i++) {
console.log( table.rows('.selected').data()[i].attributeNameFromYourself);
}
} );
(by the way: I get the data for my table using AJAX and JSON)
Go to Horizontal axis properties,choose 'Category' in AXIS type,choose "Disabled" in SIDE Margin option
File: config/database.php
change the following

TO ->
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
One of the Related posts gave me the (simple) answer.
Apparently the auto
value on the grid-template-rows
property does exactly what I was looking for.
.grid {
display:grid;
grid-template-columns: 1fr 1.5fr 1fr;
grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
grid-gap:10px;
height: calc(100vh - 10px);
}
usually i don't use for loop in R, but here is my solution using for loops and two packages : plyr and dostats
plyr is on cran and you can download dostats on https://github.com/halpo/dostats (may be using install_github from Hadley devtools package)
Assuming that i have your first two data.frame (Df.1 and Df.2) in csv files, you can do something like this.
require(plyr)
require(dostats)
files <- list.files(pattern = ".csv")
for (i in seq_along(files)) {
assign(paste("Df", i, sep = "."), read.csv(files[i]))
assign(paste(paste("Df", i, sep = ""), "summary", sep = "."),
ldply(get(paste("Df", i, sep = ".")), dostats, sum, min, mean, median, max))
}
Here is the output
R> Df1.summary
.id sum min mean median max
1 A 34 4 5.6667 5.5 8
2 B 22 1 3.6667 3.0 9
R> Df2.summary
.id sum min mean median max
1 A 21 1 3.5000 3.5 6
2 B 16 1 2.6667 2.5 5
Sorry, but in order to iterate over anything in any language, Python and English included, an index must be stored. Be it in a variable or not. Finding a way to obscure the fact that python is internally tracking the for loop won't change the fact that it is. I'd recommend just leaving it as is.
Use the built in date_sub and date_add functions to math with dates. (See http://php.net/manual/en/datetime.sub.php)
Similar to Sazzad's answer, but in procedural style PHP,
$date = date_create('2008-12-02');
date_sub($date, date_interval_create_from_date_string('5 days'));
echo date_format($date, 'Y-m-d'); //outputs 2008-11-27
use dash and lower case for attribute name ( like other answers said ) :
<test color1="color1" update-fn="updateFn()"></test>
And use "=" instead of "&" in directive scope:
scope: { updateFn: '='}
Then you can use updateFn like any other function:
<button ng-click='updateFn()'>Click</button>
There you go!
The procedure changes depending the version of MySql. Follow the procedure exactly as described for your version:
HINTS - Read before the instructions page for your version of MySql*
In step 5: Instead of run CMD, create a shortcut on your desktop calling CDM.exe. Then right-click on the shortcut and select "Execute as Administrator".
In step 6: Skip the first proposed version of the command and execute the second one, the one with the --defaults-file parameter
Once you execute the command, if everything is ok, the CMD window remains open and the command of step 6 continues executing. Simply close the window (click 'x'), and then force close MySQl from the Task Manager.
Delete the file with the SQL commands, and start again MySQL. The password must be changed now.

@columnName nvarchar(50) = 'CreatedDate';
SELECT @sqlStatement = 'ALTER TABLE ' + @tableName + ' DROP CONSTRAINT ' + dc.name + ';'
FROM sys.default_constraints AS dc
LEFT JOIN sys.columns AS sc
ON (dc.parent_column_id = sc.column_id)
WHERE dc.parent_object_id = OBJECT_ID(@tableName)
AND type_desc = 'DEFAULT_CONSTRAINT'
AND sc.name = @columnName
PRINT' ['+@tableName+']:'+@@SERVERNAME+'.'+DB_NAME()+'@'+CONVERT(VarChar, GETDATE(), 127)+'; '+@sqlStatement;
IF(LEN(@sqlStatement)>0)EXEC sp_executesql @sqlStatement
I think that the thing you must keep in mind is that your XML is being processed by a machine, not a human, so it only needs to be readable for the machine.
In other words, I think you should use whatever XML schema you need to make parsing/processing the rules as efficient as possible at run time.
As far as your current schema goes, I think that the id
attribute should be unique per element, so perhaps you should use a different attribute to capture the relationship among your IF
, THEN
, and ELSE
elements.
last but not least, a simple and efficient way to do it with a default value :
ES5
function parseBool(value, defaultValue) {
return (value == 'true' || value == 'false' || value === true || value === false) && JSON.parse(value) || defaultValue;
}
ES6 , a shorter one liner
const parseBool = (value, defaultValue) => ['true', 'false', true, false].includes(value) && JSON.parse(value) || defaultValue
JSON.parse is efficient to parse booleans
As myJSON
is an object you can just set its properties, for example:
myJSON.list1 = ["1","2"];
If you dont know the name of the properties, you have to use the array access syntax:
myJSON['list'+listnum] = ["1","2"];
If you want to add an element to one of the properties, you can do;
myJSON.list1.push("3");
Try this:
declare @var char(3)
set @var='[%]'
select Address from Accomodation where Address like '%'+@var+'%'
You must use [] cancels the effect of wildcard, so you read % as a normal character, idem about character _
This is the best answer for the way I think, but it would have been nicer in a table:
So, rewording:
You need to use \r
to use a line feed (ASCII 0x0A
, the Unix newline) in a regex replacement, but that is peculiar to the replacement - you should normally continue to expect to use \n
for line feed and \r
for carriage return.
This is because Vim used \n
in a replacement to mean the NIL character (ASCII 0x00
). You might have expected NIL to have been \0
instead, freeing \n
for its usual use for line feed, but \0
already has a meaning in regex replacements, so it was shifted to \n
. Hence then going further to also shift the newline from \n
to \r
(which in a regex pattern is the carriage return character, ASCII 0x0D
).
Character | ASCII code | C representation | Regex match | Regex replacement -------------------------+------------+------------------+-------------+------------------------ nil | 0x00 | \0 | \0 | \n line feed (Unix newline) | 0x0a | \n | \n | \r carriage return | 0x0d | \r | \r | <unknown>
NB: ^M
(Ctrl + V Ctrl + M on Linux) inserts a newline when used in a regex replacement rather than a carriage return as others have advised (I just tried it).
Also note that Vim will translate the line feed character when it saves to file based on its file format settings and that might confuse matters.
Template:
<select class="randomClass" id="randomId" (change) =
"filterSelected($event.target.value)">
<option *ngFor = 'let type of filterTypes' [value]='type.value'>{{type.display}}
</option>
</select>
Component:
public filterTypes = [{
value : 'New', display : 'Open'
},
{
value : 'Closed', display : 'Closed'
}]
filterSelected(selectedValue:string){
console.log('selected value= '+selectedValue)
}
You have to do this:
class Bar : public Foo
{
// ...
}
The default inheritance type of a class
in C++ is private
, so any public
and protected
members from the base class are limited to private
. struct
inheritance on the other hand is public
by default.
Your class shoud look something like this:
class Something { int[] array; //global array, replace type of course void function1() { array = new int[10]; //let say you declare it here that will be 10 integers in size } void function2() { array[0] = 12; //assing value at index 0 to 12. } }
That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.
First Login to your server and check the PHP version which is installed on your server.
And then run the following commands:
sudo apt-get install php7.2-curl
sudo service apache2 restart
Replace the PHP version ( php7.2 ), with your PHP version.
If you're using PowerShell v3, you can use JSON instead of a hashtable, and convert it to an object with Convert-FromJson:
@'
[
{
FileName = "Page";
ObjectName = "vExtractPage";
},
{
ObjectName = "ChecklistItemCategory";
},
{
ObjectName = "ChecklistItem";
},
]
'@ |
Convert-FromJson |
ForEach-Object {
$InputFullTableName = '{0}{1}' -f $TargetDatabase,$_.ObjectName
# In strict mode, you can't reference a property that doesn't exist,
#so check if it has an explicit filename firest.
$outputFileName = $_.ObjectName
if( $_ | Get-Member FileName )
{
$outputFileName = $_.FileName
}
$OutputFullFileName = Join-Path $OutputDirectory $outputFileName
bcp $InputFullTableName out $OutputFullFileName -T -c $ServerOption
}
Look at the filter
function.
If you just need a 1-pole low-pass filter, it's
xfilt = filter(a, [1 a-1], x);
where a = T/τ, T = the time between samples, and τ (tau) is the filter time constant.
Here's the corresponding high-pass filter:
xfilt = filter([1-a a-1],[1 a-1], x);
If you need to design a filter, and have a license for the Signal Processing Toolbox, there's a bunch of functions, look at fvtool and fdatool.
There's Pgloader that uses the aforementioned COPY
command and which can load data from csv (and MySQL, SQLite and dBase). It's also using separate threads for reading and copying data, so it's quite fast (interestingly enough, it got written from Python to Common Lisp and got a 20 to 30x speed gain, see blog post).
To load the csv file one needs to write a little configuration file, like
LOAD CSV
FROM 'path/to/file.csv' (x, y, a, b, c, d)
INTO postgresql:///pgloader?csv (a, b, d, c)

I had the same error today. I had installed Djangostack and when I checked my task manager there were two instances of mysqld running. I checked one was for wamp server and the other was for django stack. I ended the one for django stack, restarted all services in wamp server and I was able to access phpmyadmin
Perhaps a better way is using the php function in_array() like this:
$style='V';//can be 'V'ertical or 'H'orizontal
$lineBreak=($style=='V')?'<br>':'';
$name='colors';//the name of your options
$Legent="Select your $name";//dress it up in a nice fieldset with a ledgent
$options=array('red','green','blue','orange','yellow','white','black');
$boxes='';//innitiate the list of tickboxes to be generated
if(isset($_REQUEST["$name"])){
//we shall use $_REQUEST but $_POST would be better
$Checked=$_REQUEST["$name"];
}else{
$Checked=array();
}
foreach($options as $option){
$checkmark=(in_array($option,$Checked))?'checked':'';
$nameAsArray=$name.'[]';//we would like the returned data to be in an array so we end with []
$boxes.=($style=='V')?"<span class='label2' align='right'><b>$option : </b></span>":"<b>$option </b>";
$boxes.="<input style='width:2em;' type='checkbox' name='$nameAsArray' id='$option' value='$option' $checkmark >$lineBreak";
}
echo<<<EOF
<html>
<head></head>
<body>
<form name="Update" method="GET" action="{$_SERVER['PHP_SELF']}">\n
<fieldset id="tickboxes" style="width:25em;">

{$boxes}
</fieldset>
<button type="submit" >Submit Form</button>
</form>

</html>

;
To start with we have created a variable $style
to set if we want the options in a horizontal or vertical way. This will infrequence how we display our checkboxes. Next we set the $name
for our options, this is needed as a name of the array where we want to keep our options.
I have created a loop here to construct each option as given in the array $options
, then we check each item if it should be checked in our returned form. I believe this should simplify the way we can reproduce a form with checkboxes.
Change
try {
myNum = Integer.parseInt(myString.getText().toString());
} catch(NumberFormatException nfe) {
to
try {
myNum = Integer.parseInt(myString);
} catch(NumberFormatException nfe) {
You are trying to access the struct statically with a .
instead of ::
, nor are its members static
. Either instantiate ReducedForm
:
ReducedForm rf;
rf.iSimplifiedNumerator = 5;
or change the members to static
like this:
struct ReducedForm
{
static int iSimplifiedNumerator;
static int iSimplifiedDenominator;
};
In the latter case, you must access the members with ::
instead of .
I highly doubt however that the latter is what you are going for ;)
Just leave banner as being undefined and it does not get included.
the correct answer is good , but
OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream());
wr.write(parent.toString());
not work for me , instead of it , use :
byte[] outputBytes = rootJsonObject.getBytes("UTF-8");
OutputStream os = con.getOutputStream();
os.write(outputBytes);
FWIW, here is a sort method for showing which processes are using the most virt memory.
memstat | sort -k 1 -t':' -g -r | less
Sort options are set to first column, using : as column seperator, numeric sort and sort in reverse.
Try changing Deny from all
to Allow from all
in your conf and see if that helps.
A fast and concise one which was adapted from here:
String.prototype.hashCode = function() {
var hash = 5381, i = this.length
while(i)
hash = (hash * 33) ^ this.charCodeAt(--i)
return hash >>> 0;
}
first: just use add method instead of replace method of FragmentTransaction class then you have to add secondFragment to stack by addToBackStack method
second :on back click you have to call popBackStackImmediate()
Fragment sourceFragment = new SourceFragment ();
final Fragment secondFragment = new SecondFragment();
final FragmentTransaction ft = getChildFragmentManager().beginTransaction();
ft.add(R.id.child_fragment_container, secondFragment );
ft.hide(sourceFragment );
ft.addToBackStack(NewsShow.class.getName());
ft.commit();
((SecondFragment)secondFragment).backFragmentInstanceClick = new SecondFragment.backFragmentNewsResult()
{
@Override
public void backFragmentNewsResult()
{
getChildFragmentManager().popBackStackImmediate();
}
};
$sql = "SELECT * FROM table_name ORDER BY ID DESC LIMIT 1";
$records = mysql_query($sql);
you can change LIMIT 1 to LIMIT any number you want
This will show you the last INSERTED row first.
right click you project name then open the properties windows. downgrade your Target framework version, build Solution then upgrade your Target framework version to the latest, build Solution .
It appears that for some applications, there is a far simpler approach to multi dimensional associative arrays in javascript.
Given that the internal representation of all arrays are actually as objects of objects, it has been shown that the access time for numerically indexed elements is actually the same as for associative (text) indexed elements.
the access time for first-level associative indexed elements does not rise as the number of actual elements increases.
Given this, there may be many cases where it is actually better to use a concatenated string approach to create the equivalence of a multidimensional elements. For example:
store['fruit']['apples']['granny']['price] = 10
store['cereal']['natural']['oats']['quack'] = 20
goes to:
store['fruit.apples.granny.price'] = 10
store['cereal.natural.oats.quack'] = 20
Advantages include:
1) You can use the !important
rule, like this:
.selected
{
background-color:red !important;
}
See http://www.w3.org/TR/CSS2/cascade.html#important-rules for more info.
2) In your example you can also get the red background by using ul.nav li.selected
instead of just .selected
. This makes the selector more specific.
See http://www.w3.org/TR/CSS2/cascade.html#specificity for more info.
Lets say you saved your software onto your desktop.
if you want to remove an entire folder like an uninstaller program you could use this.
cd C:\Users\User\Detsktop\
rd /s /q SOFTWARE
this will delete the entire folder called software and all of its files and subfolders
Make Sure You Delete The Correct Folder Cause This Does Not Have A Yes / No Option
Another possible solution, in case you're looking for all the words in a given string, which contain a number
\w*\d{1,}\w*
\w*
- Matches 0 or more instances of [A-Za-z0-9_]\d{1,}
- Matches 1 or more instances of a number\w*
- Matches 0 or more instances of [A-Za-z0-9_]The whole point in \w*
is to allow not having a character in the beginning or at the end of a word. This enables capturing the first and last words in the text.
If the goal here is to only get the numbers without the words, you can omit both \w*
.

Check this example in regexr - https://regexr.com/5ff7q
for background worker i think you should try this technique it will help to call as many as pages you like all pages will run at once independently without waiting for each page response as asynchronous.
form_action_page.php
<?php
post_async("http://localhost/projectname/testpage.php", "Keywordname=testValue");
//post_async("http://localhost/projectname/testpage.php", "Keywordname=testValue2");
//post_async("http://localhost/projectname/otherpage.php", "Keywordname=anyValue");
//call as many as pages you like all pages will run at once //independently without waiting for each page response as asynchronous.
//your form db insertion or other code goes here do what ever you want //above code will work as background job this line will direct hit before //above lines response
?>
<?php
/*
* Executes a PHP page asynchronously so the current page does not have to wait for it to finish running.
*
*/
function post_async($url,$params)
{
$post_string = $params;
$parts=parse_url($url);
$fp = fsockopen($parts['host'],
isset($parts['port'])?$parts['port']:80,
$errno, $errstr, 30);
$out = "GET ".$parts['path']."?$post_string"." HTTP/1.1\r\n";//you can use POST instead of GET if you like
$out.= "Host: ".$parts['host']."\r\n";
$out.= "Content-Type: application/x-www-form-urlencoded\r\n";
$out.= "Content-Length: ".strlen($post_string)."\r\n";
$out.= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
fclose($fp);
}
?>
testpage.php
<?
echo $_REQUEST["Keywordname"];//case1 Output > testValue
//here do your background operations it will not halt main page
?>
PS:if you want to send url parameters as loop then follow this answer :https://stackoverflow.com/a/41225209/6295712
I agree with Petar Ivanov but it is best if we implement in following way:
public String replace(String str, int index, char replace){
if(str==null){
return str;
}else if(index<0 || index>=str.length()){
return str;
}
char[] chars = str.toCharArray();
chars[index] = replace;
return String.valueOf(chars);
}
requests
has built-in .json()
method
import requests
requests.get(url).json()
You can use this OrderedDict recipe
written by Raymond Hettinger and modify it to add a rename
method, but this is going to be a O(N) in complexity:
def rename(self,key,new_key):
ind = self._keys.index(key) #get the index of old key, O(N) operation
self._keys[ind] = new_key #replace old key with new key in self._keys
self[new_key] = self[key] #add the new key, this is added at the end of self._keys
self._keys.pop(-1) #pop the last item in self._keys
Example:
dic = OrderedDict((("a",1),("b",2),("c",3)))
print dic
dic.rename("a","foo")
dic.rename("b","bar")
dic["d"] = 5
dic.rename("d","spam")
for k,v in dic.items():
print k,v
output:
OrderedDict({'a': 1, 'b': 2, 'c': 3})
foo 1
bar 2
c 3
spam 5

In my example, I have an ActionFilterAttribute that I was using to update the values of a json patch document. I didn't what the T model was for the patch document to I had to serialize & deserialize it to a plain JsonPatchDocument, modify it, then because I had the type, serialize & deserialize it back to the type again.
Type originalType = //someType that gets passed in to my constructor.
var objectAsString = JsonConvert.SerializeObject(myObjectWithAGenericType);
var plainPatchDocument = JsonConvert.DeserializeObject<JsonPatchDocument>(objectAsString);
var plainPatchDocumentAsString= JsonConvert.SerializeObject(plainPatchDocument);
var modifiedObjectWithGenericType = JsonConvert.DeserializeObject(plainPatchDocumentAsString, originalType );
I had in PATH
:
C:\ProgramData\Oracle\Java\javapath;C:\Program Files\Java\jdk1.8.0_92\bin;<others omitted>
I removed:
C:\ProgramData\Oracle\Java\javapath;
and that fixed the issue for me. java -version
now gives details about the Java version, etc.
If possible use Visual Studio. The Microsoft SQL Server Data Tools (SSDT) bring a built in functionality for this since the March 2014 release:
Note: Be careful, the "View Data" window is just like SSMS "Edit Top 200 Rows"- you can edit data right away
(Tested with Visual Studio 2015 with Microsoft SQL Server Data Tools (SSDT) Version 14.0.60812.0 and Microsoft SQL Server 2012)
alter table table_name change old_col_name new_col_name new_col_type;
Here is the example
hive> alter table test change userVisit userVisit2 STRING;

hive> describe test;
OK
uservisit2 string

uuid string
Time taken: 0.213 seconds, Fetched: 3 row(s)
$new_website = substr($str, ($pos = strrpos($str, '//')) !== false ? $pos + 2 : 0);
This would remove everything before the '//'.
EDIT
This one is tested. Using strrpos()
instead or strpos()

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,
2) AbstractTableModel should be useful, where is in the JTable
required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel
,
3) consider using DefaultTableModel
, (if you are not sure about how to works) instead of AbstractTableModel
,
could be generated from simple code:
import javax.swing.*;
import javax.swing.table.*;
public class TableCheckBox extends JFrame {
private static final long serialVersionUID = 1L;
private JTable table;
public TableCheckBox() {
Object[] columnNames = {"Type", "Company", "Shares", "Price", "Boolean"};
Object[][] data = {
{"Buy", "IBM", new Integer(1000), new Double(80.50), false},
{"Sell", "MicroSoft", new Integer(2000), new Double(6.25), true},
{"Sell", "Apple", new Integer(3000), new Double(7.35), true},
{"Buy", "Nortel", new Integer(4000), new Double(20.00), false}
};
DefaultTableModel model = new DefaultTableModel(data, columnNames);
table = new JTable(model) {
private static final long serialVersionUID = 1L;

@Override
public Class getColumnClass(int column) {
switch (column) {
case 0:

No other "addClass" methods worked for me when adding a class to an 'a' element on menu except this one:
$(function () {
var url = window.location.pathname,
urlRegExp = new RegExp(url.replace(/\/$/, '') + "$");
$('a').each(function () {
if (urlRegExp.test(this.href.replace(/\/$/, ''))) {
$(this).addClass('active');
}
});
});
This took me four hours to find it.
1) In case you want to reload the same URL:
mWebView.loadUrl("http://www.websitehere.php");
so the full code would be
newButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
dgeActivity.this.mWebView.loadUrl("http://www.websitehere.php");
}});
2) You can also call mWebView.reload()
but be aware this reposts a page if the request was POST, so only works correctly with GET.
Another way to get this error, is if you have duplicate or conflicting ~/.ssh/*
entries. First check what is on your ssh key-chain with:
$ ssh-add -l
2048 SHA256:<hash1> [email protected] (RSA)
2048 SHA256:<hash2> [email protected] (RSA)
2048 SHA256:<hash3> [email protected] (RSA)
As you can see there are two emails which are the same, and easy for you to get confused. Then check your config
file:
$ cat ~/.ssh/config
# GitHub: [email protected]
Host github_ex
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/github_ex
# GitHub: [email protected]
Host github
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/github
# Bitbucket: [email protected]
Host bitbucket
HostName bitbucket.org
PreferredAuthentications publickey
IdentityFile ~/.ssh/bitbuc
Here you see that you have two different email accounts to github but same HostName
. Someone is bound to get confused, including your git.
To resolve, manually remove (after copying) the (default) files:
cd ~/.ssh
rm id_rsa
rm id_rsa.pub
Now copy back the one you want to use, for example Host github
:
cp -a github id_rsa
cp -a github.pub id_rsa.pub
Then try again.
For some reason, removing keys with ssh-add -d id_rsa
didn't work as expected, as it seem that key-chain is cached.
One needs to install magrittr
as follows
install.packages("magrittr")
Then, in one's script, don't forget to add on top
library(magrittr)
For the meaning of the operator %>%
you might want to consider this question: What does %>% function mean in R?
Note that the same operator would also work with the library dplyr
, as it imports from magrittr
.
dplyr
used to have a similar operator (%.%
), which is now deprecated. Here we can read about the differences between %.%
(deprecated operator from the library dplyr
) and %>%
(operator from magrittr
, that is also available in dplyr
)
Almost correctly.. Look at the joins, you are referring the wrong fields
SELECT student.firstname,
student.lastname,
exam.name,
exam.date,
grade.grade
FROM grade
INNER JOIN student ON student.studentId = grade.fk_studentId
INNER JOIN exam ON exam.examId = grade.fk_examId
ORDER BY exam.date
I received a IllegalMonitorStateException
while trying to wake up a thread in / from a different class
/ thread. In java 8
you can use the lock
features of the new Concurrency API instead of synchronized
functions.
I was already storing objects for asynchronous
websocket transactions in a WeakHashMap
. The solution in my case was to also store a lock
object in a ConcurrentHashMap
for synchronous
replies. Note the condition.await
(not .wait
).
To handle the multi threading I used a Executors.newCachedThreadPool()
to create a thread pool.
To find all the keys that map to that value, iterate through all the pairs in the hashmap, using map.entrySet()
.
Yes, we have a way to get screenshot extension of .png using python webdriver

Take a look into NSColorWell class reference.
Try this: Pick a random name "Lastname, Firstname" and look it up in your phonebook.
1st time: start at the beginning of the book, reading names until you find it, or else find the place where it would have occurred alphabetically and note that it isn't there.
2nd time: Open the book at the half way point and look at the page. Ask yourself, should this person be to the left or to the right. Whichever one it is, take that 1/2 and find the middle of it. Repeat this procedure until you find the page where the entry should be and then either apply the same process to columns, or just search linearly along the names on the page as before.
Time both methods and report back!
[also consider what approach is better if all you have is a list of names, not sorted...]
Within your component, you can define an array of number (ES6) as described below:
export class SampleComponent {
constructor() {
this.numbers = Array(5).fill(0).map((x,i)=>i);
}
}
See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.
You can then iterate over this array with ngFor
:
@View({
template: `
<ul>
<li *ngFor="let number of numbers">{{number}}</li>
</ul>
`
})
export class SampleComponent {
(...)
}
Or shortly:
@View({
template: `
<ul>
<li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
</ul>
`
})
export class SampleComponent {
(...)
}
Hope it helps you, Thierry
Edit: Fixed the fill statement and template syntax.
Check your .bashrc
file for aliases.
Use numpy.dot
or a.dot(b)
. See the documentation here.
>>> a = np.array([[ 5, 1 ,3],
[ 1, 1 ,1],
[ 1, 2 ,1]])
>>> b = np.array([1, 2, 3])
>>> print a.dot(b)
array([16, 6, 8])
This occurs because numpy arrays are not matrices, and the standard operations *, +, -, /
work element-wise on arrays. Instead, you could try using numpy.matrix
, and *
will be treated like matrix multiplication.
Also know there are other options:
As noted below, if using python3.5+ the @
operator works as you'd expect:
>>> print(a @ b)
array([16, 6, 8])
If you want overkill, you can use numpy.einsum
. The documentation will give you a flavor for how it works, but honestly, I didn't fully understand how to use it until reading this answer and just playing around with it on my own.
>>> np.einsum('ji,i->j', a, b)
array([16, 6, 8])
As of mid 2016 (numpy 1.10.1), you can try the experimental numpy.matmul
, which works like numpy.dot
with two major exceptions: no scalar multiplication but it works with stacks of matrices.
>>> np.matmul(a, b)
array([16, 6, 8])
numpy.inner
functions the same way as numpy.dot
for matrix-vector multiplication but behaves differently for matrix-matrix and tensor multiplication (see Wikipedia regarding the differences between the inner product and dot product in general or see this SO answer regarding numpy's implementations).
>>> np.inner(a, b)
array([16, 6, 8])
# Beware using for matrix-matrix multiplication though!
>>> b = a.T
>>> np.dot(a, b)
array([[35, 9, 10],
[ 9, 3, 4],
[10, 4, 6]])
>>> np.inner(a, b)
array([[29, 12, 19],
[ 7, 4, 5],
[ 8, 5, 6]])
If you have tensors (arrays of dimension greater than or equal to one), you can use numpy.tensordot
with the optional argument axes=1
:
>>> np.tensordot(a, b, axes=1)
array([16, 6, 8])
Don't use numpy.vdot
if you have a matrix of complex numbers, as the matrix will be flattened to a 1D array, then it will try to find the complex conjugate dot product between your flattened matrix and vector (which will fail due to a size mismatch n*m
vs n
).
There is no simple command available to find out the largest files/directories on a Linux/UNIX/BSD filesystem. However, combination of following three commands (using pipes) you can easily find out list of largest files:
# du -a /var | sort -n -r | head -n 10
If you want more human readable output try:
$ cd /path/to/some/var
$ du -hsx * | sort -rh | head -10
Where,
See the above definition where it states that a callback function is passed off to some other function and at some point it is called.
In C++ it is desirable to have callback functions call a classes method. When you do this you have access to the member data. If you use the C way of defining a callback you will have to point it to a static member function. This is not very desirable.
Here is how you can use callbacks in C++. Assume 4 files. A pair of .CPP/.H files for each class. Class C1 is the class with a method we want to callback. C2 calls back to C1's method. In this example the callback function takes 1 parameter which I added for the readers sake. The example doesn't show any objects being instantiated and used. One use case for this implementation is when you have one class that reads and stores data into temporary space and another that post processes the data. With a callback function, for every row of data read the callback can then process it. This technique cuts outs the overhead of the temporary space required. It is particularly useful for SQL queries that return a large amount of data which then has to be post-processed.
/////////////////////////////////////////////////////////////////////
// C1 H file
class C1
{
public:
C1() {};
~C1() {};
void CALLBACK F1(int i);
};
/////////////////////////////////////////////////////////////////////
// C1 CPP file
void CALLBACK C1::F1(int i)
{
// Do stuff with C1, its methods and data, and even do stuff with the passed in parameter
}
/////////////////////////////////////////////////////////////////////
// C2 H File
class C1; // Forward declaration
class C2
{
typedef void (CALLBACK C1::* pfnCallBack)(int i);
public:
C2() {};
~C2() {};
void Fn(C1 * pThat,pfnCallBack pFn);
};
/////////////////////////////////////////////////////////////////////
// C2 CPP File
void C2::Fn(C1 * pThat,pfnCallBack pFn)
{
// Call a non-static method in C1
int i = 1;
(pThat->*pFn)(i);
}

Released in June 2012, Eclipse for Mobile Developers is an awesome starting point for developers looking to focus on Android development. I've used it for several projects since August and haven't been disappointed.
git merge origin/master

worked for me. So to merge master into feature branch you may use:
git checkout feature_branch
git merge origin/master
I had a somehow similar problem working with AFNetworking from a Swift codebase so I'm just leaving this here in the remote case someone is as unlucky as me having to work in such a setup. If you are, I feel you buddy, stay strong!
The operation was failing due to "unacceptable content-type", despite me actually setting the acceptableContentTypes
with a Set
containing the content type value in question.
The solution for me was to tweak the Swift code to be more Objective-C friendly, I guess:
serializer.acceptableContentTypes = NSSet(array: ["application/xml", "text/xml", "text/plain"]) as Set<NSObject>
This can be accomplished with a simple VBA function. Excel has support for a Worksheet Change Sub which can be programmed to put a date in a related column every time it fires.
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column = 2 And Target.Offset(0, 3).Value = "" Then
Target.Offset(0, 3) = Format(Now(), "HH:MM:SS")
End If
End Sub
A quick explanation. The following "if" statement checks for two things: (1) if it is the second column that changed (Column B), and (2) if the cell 3 columns over (Column E) is currently empty.
If Target.Column = 2 And Target.Offset(0, 3).Value = "" Then
If both conditions are true, then it puts the date into the cell in Column E with the NOW()
function.
Target.Offset(0, 3) = Format(Now(), "HH:MM:SS")
Synchronized simply means that multiple threads if associated with single object can prevent dirty read and write if synchronized block is used on particular object. To give you more clarity , lets take an example :
class MyRunnable implements Runnable {
int var = 10;
@Override
public void run() {
call();
}
public void call() {
synchronized (this) {
for (int i = 0; i < 4; i++) {
var++;
System.out.println("Current Thread " + Thread.currentThread().getName() + " var value "+var);
}
}
}
}
public class MutlipleThreadsRunnable {
public static void main(String[] args) {
MyRunnable runnable1 = new MyRunnable();
MyRunnable runnable2 = new MyRunnable();
Thread t1 = new Thread(runnable1);
t1.setName("Thread -1");
Thread t2 = new Thread(runnable2);
t2.setName("Thread -2");
Thread t3 = new Thread(runnable1);
t3.setName("Thread -3");
t1.start();
t2.start();
t3.start();
}
}
We've created two MyRunnable class objects , runnable1 being shared with thread 1 and thread 3 & runnable2 being shared with thread 2 only. Now when t1 and t3 starts without synchronized being used , PFB output which suggest that both threads 1 and 3 simultaneously affecting var value where for thread 2 , var has its own memory.
Without Synchronized keyword
Current Thread Thread -1 var value 11
Current Thread Thread -2 var value 11
Current Thread Thread -2 var value 12
Current Thread Thread -2 var value 13
Current Thread Thread -2 var value 14
Current Thread Thread -1 var value 12
Current Thread Thread -3 var value 13
Current Thread Thread -3 var value 15
Current Thread Thread -1 var value 14
Current Thread Thread -1 var value 17
Current Thread Thread -3 var value 16
Current Thread Thread -3 var value 18
Using Synchronzied, thread 3 waiting for thread 1 to complete in all scenarios. There are two locks acquired , one on runnable1 shared by thread 1 and thread 3 and another on runnable2 shared by thread 2 only.
Current Thread Thread -1 var value 11
Current Thread Thread -2 var value 11
Current Thread Thread -1 var value 12
Current Thread Thread -2 var value 12
Current Thread Thread -1 var value 13
Current Thread Thread -2 var value 13
Current Thread Thread -1 var value 14
Current Thread Thread -2 var value 14
Current Thread Thread -3 var value 15
Current Thread Thread -3 var value 16
Current Thread Thread -3 var value 17
Current Thread Thread -3 var value 18
:unchecked
is not defined in the Selectors or CSS UI level 3 specs, nor has it appeared in level 4 of Selectors.
In fact, the quote from W3C is taken from the Selectors 4 spec. Since Selectors 4 recommends using :not(:checked)
, it's safe to assume that there is no corresponding :unchecked
pseudo. Browser support for :not()
and :checked
is identical, so that shouldn't be a problem.
This may seem inconsistent with the :enabled
and :disabled
states, especially since an element can be neither enabled nor disabled (i.e. the semantics completely do not apply), however there does not appear to be any explanation for this inconsistency.
(:indeterminate
does not count, because an element can similarly be neither unchecked, checked nor indeterminate because the semantics don't apply.)
Another option that could help some OS X users is Transmit.
It's an FTP program that also let you connect to your S3 files. And, it has an option to mount any FTP or S3 storage as a folder in the Finder, but it's only for a limited time.
I wasn't able to copy to my clipboard's system because I had this in my ~/.vimrc file:

For anyone looking to activate a views tap gesture recognizer without having direct access to the gesture recognizer... when returning to a page I had to fill bubbles that were previously filled by tapping. I kept track of those bubbles tags (bubs) ...
func fillBubs(bubs: [Int]) {
for bub in bubs {
let bubble = view.viewWithTag(bub)
if bubble == nil {continue}
for g in bubble!.gestureRecognizers! {
let tap = g as! UITapGestureRecognizer
handleBub(tap)
}
}
}

let bubble = sender?.view!
bubble?.layer.backgroundColor = #colorLiteral(red: 0, green: 0, blue: 0, alpha: 1)

along with these two variants, there is also jade.renderFile
which generates html that need not be passed to the client.
usage-
var jade = require('jade');
exports.getJson = getJson;
function getJson(req, res) {
var html = jade.renderFile('views/test.jade', {some:'json'});
res.send({message: 'i sent json'});
}
getJson()
is available as a route in app.js.
You can easily get data from another table. You have to add fields only you want.
The mysql query is:
INSERT INTO table_name1(fields you want)
SELECT fields you want FROM table_name2
where, the values are copied from table2 to table1
The capitalization is wrong, and you have an extra argument.
Do this instead:
$('img#thumb').removeAttr('id');
For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.
I need this for Unity in C# so I thought that it might be useful for some one. This is an example of passing a list of AudioSources to whatever function you want:
private void ChooseClip(GameObject audioSourceGameObject , List<AudioClip> sources) {
audioSourceGameObject.GetComponent<AudioSource> ().clip = sources [0];
}
The button code should be moved to the PlaceholderFragment()
class. There you will call the layout fragment_main.xml
in the onCreateView
method. Like so
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button) view.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
onButtonClick((Button) view);
}
});
return view;
}
The other answers point out how to accomplish this, but you should keep in mind the consequences since this is a remote repository.
The git tag man page, in the On Retagging section, has a good explanation of how to courteously inform the remote repo's other users of the change. They even give a handy announcement template for communicating how others should get your changes.
I had similar situation. Writing custom filter worked for me. Hope this helps!
JS:
App.filter('searchMovies', function() {
return function (items, letter) {
var resulsts = [];
var itemMatch = new RegExp(letter, 'i');
for (var i = 0; i < items.length; i++) {
var item = items[i];
if ( itemMatch.test(item.name) || itemMatch.test(item.genre)) {
results.push(item);
}
}
return results;
};
});
HTML:
<div ng-controller="MoviesCtrl">
<ul>
<li ng-repeat="movie in movies | searchMovies:filterByGenres">
{{ movie.name }} {{ movie.genre }}
</li>
</ul>
</div>
HttpContext.Response.AddHeader("content-disposition","attachment; filename=form.pdf");
if the filename is generating dynamically then how to define filename here, it is generating through guid here.
One thing you can do is this:
$(this)[0].value = "Something";
This allows jQuery to return the javascript object for that element, and you can bypass jQuery Functions.
I tried ComboBox1_KeyPress but it allows to delete the character & you can also use copy paste command. My DropDownStyle is set to DropDownList but still no use. So I did below step to avoid combobox text editing.
Below code handles delete & backspace key. And also disables combination with control key (e.g. ctr+C or ctr+X)
Private Sub CmbxInType_KeyDown(sender As Object, e As KeyEventArgs) Handles CmbxInType.KeyDown
If e.KeyCode = Keys.Delete Or e.KeyCode = Keys.Back Then
e.SuppressKeyPress = True
End If
If Not (e.Control AndAlso e.KeyCode = Keys.C) Then
e.SuppressKeyPress = True
End If
End Sub
In form load use below line to disable right click on combobox control to avoid cut/paste via mouse click.
CmbxInType.ContextMenu = new ContextMenu()
If you want to print "all" lines, there is a simple working solution:
grep "test" -A 9999999 -B 9999999
To get the hostname: location.hostname
But your example is looking for the scheme as well, so location.origin
appears to do what you want in Chrome, but gets not mention in the Mozdev docs. You can construct it with
location.protocol + '//' + location.hostname
If you want the port number as well (for when it isn't 80) then:
location.protocol + '//' + location.host

The problem is:
$ docker-compose stop nginx
didn't work (you said it is still running). If you are going to rebuild it anyway, you can try killing it:
$ docker-compose kill nginx
If it still doesn't work, try to stop it with docker directly:
$ docker stop nginx
or delete it
$ docker rm -f nginx
If that still doesn't work, check your version of docker, you might want to upgrade.
It might be a bug, you could check if one matches your system/version. Here are a couple, for ex: https://github.com/docker/docker/issues/10589
https://github.com/docker/docker/issues/12738
As a workaround, you could try to kill the process.
$ ps aux | grep docker
$ kill 225654 # example process id
I see that the originator found out that the error occurred when trying to save the filename with an entire path. Actually it's enough to have a ":"
in the file name to get this error. If there might be ":"
in your file name (for instance if you have a date stamp in your file name) make sure you replace these with something else. I.e:
string fullFileName = fileName.Split('.')[0] + "(" + DateTime.Now.ToString().Replace(':', '-') + ")." + fileName.Split('.')[1];
The most common approach is to either lowercase or uppercase the search string and the data. But there are two problems with that.
There are at least three less frequently used solutions that might be more effective.
CREATE INDEX ON groups (name::citext);
. (But see below.)CREATE
INDEX ON groups (LOWER(name));
. Having done that, you can take advantage
of the index with queries like SELECT id FROM groups WHERE LOWER(name) = LOWER('ADMINISTRATOR');
, or SELECT id FROM groups WHERE LOWER(name) = 'administrator';
You have to remember to use LOWER(), though.The citext module doesn't provide a true case-insensitive data type. Instead, it behaves as if each string were lowercased. That is, it behaves as if you had called lower()
on each string, as in number 3 above. The advantage is that programmers don't have to remember to lowercase strings. But you need to read the sections "String Comparison Behavior" and "Limitations" in the docs before you decide to use citext.
You can also send characters that you want to be trimed
extension String {
func trim() -> String {
return self.trimmingCharacters(in: .whitespacesAndNewlines)
}
func trim(characterSet:CharacterSet) -> String {
return self.trimmingCharacters(in: characterSet)
}
}
validationMessage = validationMessage.trim(characterSet: CharacterSet(charactersIn: ","))
Try to implement dynamic data structure such as a linked list
I had this issue when converting an older project to use a new version of Visual Studio. Upon conversion, the project target framework was set to 2.0
I was able to solve this issue by changing the target framework to be 3.5.
Since the syntaxes are equivalent (in MySQL anyhow), I prefer the INSERT INTO table SET x=1, y=2
syntax, since it is easier to modify and easier to catch errors in the statement, especially when inserting lots of columns. If you have to insert 10 or 15 or more columns, it's really easy to mix something up using the (x, y) VALUES (1,2)
syntax, in my opinion.
If portability between different SQL standards is an issue, then maybe INSERT INTO table (x, y) VALUES (1,2)
would be preferred.
And if you want to insert multiple records in a single query, it doesn't seem like the INSERT INTO ... SET
syntax will work, whereas the other one will. But in most practical cases, you're looping through a set of records to do inserts anyhow, though there could be some cases where maybe constructing one large query to insert a bunch of rows into a table in one query, vs. a query for each row, might have a performance improvement. Really don't know.
I'll post what worked for me, thanks to @xavi-montero.
Put your CSS in your bundle's Resource/public/css
directory, and your images in say Resource/public/img
.
Change assetic paths to the form 'bundles/mybundle/css/*.css'
, in your layout.
In config.yml
, add rule css_rewrite
to assetic:
assetic:
filters:
cssrewrite:
apply_to: "\.css$"
Now install assets and compile with assetic:
$ rm -r app/cache/* # just in case
$ php app/console assets:install --symlink
$ php app/console assetic:dump --env=prod
This is good enough for the development box, and --symlink
is useful, so you don't have to reinstall your assets (for example, you add a new image) when you enter through app_dev.php
.
For the production server, I just removed the '--symlink' option (in my deployment script), and added this command at the end:
$ rm -r web/bundles/*/css web/bundles/*/js # all this is already compiled, we don't need the originals
All is done. With this, you can use paths like this in your .css files: ../img/picture.jpeg
>>> str(10)
'10'
>>> int('10')
10
Links to the documentation:
Conversion to a string is done with the builtin str()
function, which basically calls the __str__()
method of its parameter.
Handling events with React elements is very similar to handling events on DOM elements. There are some syntactic differences:
- React events are named using camelCase, rather than lowercase.
- With JSX you pass a function as the event handler, rather than a string.
So as mentioned in React documentation, they quite similar to normal HTML when it comes to Event Handling, but event names in React using camelcase, because they are not really HTML, they are JavaScript, also, you pass the function while we passing function call in a string format for HTML, they are different, but the concepts are pretty similar...
Look at the example below, pay attention to the way event get passed to the function:
function ActionLink() {
function handleClick(e) {
e.preventDefault();
console.log('The link was clicked.');
}
return (
<a href="#" onClick={handleClick}>
Click me
</a>
);
}
iOS makes phone numbers clickable by defaults (for obvious reasons). Of course, that adds an extra tag which is overriding your styling if your phone number isn’t already a link.
To fix it, try adding this to your stylesheet: a[href^=tel] { color: inherit; text-decoration: none; }
That should keep your phone numbers styled as you expect without adding extra markup.
Use fnmatch
:
import fnmatch
lst = ['this','is','just','a','test']
filtered = fnmatch.filter(lst, 'th?s')
If you want to allow _
as a wildcard, just replace all underscores with '?'
(for one character) or *
(for multiple characters).
If you want your users to use even more powerful filtering options, consider allowing them to use regular expressions.
Just to add that the answer that Alex provided worked for me, and not the one that is highlighted as an answer.
This one didn't work for me
$('#country.save')
But this one did:
$('#country .save')
so my conclusion is to use the space. Now I don't know if it's to the new version of jQuery that I'm using (1.5.1), but anyway hope this helps to anyone with similar problem that I've had.
edit: Full credit for explanation (in the comment to Alex's answer) goes to Felix Kling who says:
The space is the descendant selector, i.e. A B means "Match all elements that
match B which are a descendant of elements matching A". AB means "select all
element that match A and B". So it really depends on what you want to achieve. #country.save
and #country .save
are not equivalent.
Doubles don't have decimal places - they're not based on decimal digits to start with. You could get "the closest double to the current value when truncated to three decimal digits", but it still wouldn't be exactly the same. You'd be better off using decimal
.
Having said that, if it's only the way that rounding happens that's a problem, you can use Math.Truncate(value * 1000) / 1000;
which may do what you want. (You don't want rounding at all, by the sounds of it.) It's still potentially "dodgy" though, as the result still won't really just have three decimal places. If you did the same thing with a decimal value, however, it would work:
decimal m = 12.878999m;
m = Math.Truncate(m * 1000m) / 1000m;
Console.WriteLine(m); // 12.878
EDIT: As LBushkin pointed out, you should be clear between truncating for display purposes (which can usually be done in a format specifier) and truncating for further calculations (in which case the above should work).
With selectable date ranges you might want to use something like this. My solution prevents selecting #from_date bigger than #to_date and changes #to_date startDate every time when user selects new date in #from_date box:
JS file:
var startDate = new Date('01/01/2012');
var FromEndDate = new Date();
var ToEndDate = new Date();
ToEndDate.setDate(ToEndDate.getDate()+365);
$('.from_date').datepicker({
weekStart: 1,
startDate: '01/01/2012',
endDate: FromEndDate,
autoclose: true
})
.on('changeDate', function(selected){
startDate = new Date(selected.date.valueOf());
startDate.setDate(startDate.getDate(new Date(selected.date.valueOf())));
$('.to_date').datepicker('setStartDate', startDate);
});
$('.to_date')
.datepicker({
weekStart: 1,
startDate: startDate,
endDate: ToEndDate,
autoclose: true
})
.on('changeDate', function(selected){
FromEndDate = new Date(selected.date.valueOf());
FromEndDate.setDate(FromEndDate.getDate(new Date(selected.date.valueOf())));
$('.from_date').datepicker('setEndDate', FromEndDate);
});
HTML:
<input class="from_date" placeholder="Select start date" contenteditable="false" type="text">
<input class="to_date" placeholder="Select end date" contenteditable="false" type="text"
And do not forget to include bootstrap datepicker.js and .css files aswell.
onSaveInstanceState()
is a method used to store data before pausing the activity.Description : Hook allowing a view to generate a representation of its internal state that can later be used to create a new instance with that same state. This state should only contain information that is not persistent or can not be reconstructed later. For example, you will never store your current position on screen because that will be computed again when a new instance of the view is placed in its view hierarchy.
onRestoreInstanceState()
is method used to retrieve that data back.Description : This method is called after onStart() when the activity is being re-initialized from a previously saved state, given here in savedInstanceState. Most implementations will simply use onCreate(Bundle) to restore their state, but it is sometimes convenient to do it here after all of the initialization has been done or to allow subclasses to decide whether to use your default implementation. The default implementation of this method performs a restore of any view state that had previously been frozen by onSaveInstanceState(Bundle).
Consider this example here:
You app has 3 edit boxes where user was putting in some info , but he gets a call so if you didn't use the above methods what all he entered will be lost.
So always save the current data in onPause()
method of Activity as a bundle & in onResume()
method call the onRestoreInstanceState()
method .
Please see :
How to use onSavedInstanceState example please
http://www.how-to-develop-android-apps.com/tag/onrestoreinstancestate/
I'll just update the code to contain the changes, and comment it to so that you can see what's going on clearly...
<?php
include("templates/header.htm");
// Set the default name
$action = 'index';
// Specify some disallowed paths
$disallowed_paths = array('header', 'footer');
if (!empty($_GET['action'])) {
$tmp_action = basename($_GET['action']);
// If it's not a disallowed path, and if the file exists, update $action
if (!in_array($tmp_action, $disallowed_paths) && file_exists("templates/{$tmp_action}.htm"))
$action = $tmp_action;
}
// Include $action
include("templates/$action.htm");
include("templates/footer.htm");
<form onSubmit={(e) => {this.doSomething(); e.preventDefault();}}></form>
it work fine for me
From my recent experience, JsonReader#setLenient
basically makes the parser very tolerant, even to allow malformed JSON data.
But for certain data retrieved from your trusted RESTful API(s), this error might be caused by trailing white spaces. In such cases, simply trim
the data would avoid the error:
String trimmed = result1.trim();
Then gson.fromJson(trimmed, T)
might work. Surely this only covers a special case, so YMMV.
You use new
to perform dynamic allocation. It returns a pointer that points to the dynamically allocated object.
You have no reason to use new
, since A
is an automatic variable. You can simply initialise A
using its constructor:
vector<vector<int> > A(dimension, vector<int>(dimension));
I later found that, there is an official way to see all the routes, by going to http://localhost:3000/rails/info/routes. Official docs: https://guides.rubyonrails.org/routing.html#listing-existing-routes
Though, it may be late, But I love the error page which displays all the routes. I usually try to go at /routes
(or some bogus) path directly from the browser. Rails server automatically gives me a routing error page as well as all the routes and paths defined. That was very helpful :)
So, Just go to http://localhost:3000/routes
I use the following method when sending a List<MySerializableObject>
via intent:
List<Thumbnail> thumbList = new ArrayList<>();
//Populate ...
Intent intent = new Intent(context, OtherClass.class);
intent.putExtra("ThumbArray", thumbList.toArray(new Thumbnail[0]));
//Send intent...
And retrieving it like so:
Thumbnail[] thumbArr = (Thumbnail[]) getIntent().getSerializableExtra("ThumbArray");
if (thumbArr != null) {
List<Thumbnail> thumbList = Arrays.asList(thumbArr);
}
In my case, I was having a similar problem:
/usr/bin/ld: Bank.cpp:(.text+0x19c): undefined reference to 'Account::SetBank(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)' collect2: error: ld returned 1 exit status
After some researches, I realized that the problem was being generated by the way that Visual Studio Code was compiling the Bank.cpp file. So, to solve that, I just prompted the follow command in order to compile the c++ file sucessful:
g++ Bank.cpp Account.cpp -o Bank
With the command above, It was able to linkage correctly the Header, Implementations and Main c++ files.
OBS: My g++ version: 9.3.0 on Ubuntu 20.04
int main (void)
{
//print time in seconds from 1 Jan 1970 using c
float n = time(NULL);
printf("%.2f\n" , n);
}
this prints 1481986944.00 (at this moment).
The main reason you use the default queue over the main queue is to run tasks in the background.
For instance, if I am downloading a file from the internet and I want to update the user on the progress of the download, I will run the download in the priority default queue and update the UI in the main queue asynchronously.
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
//Background Thread
dispatch_async(dispatch_get_main_queue(), ^(void){
//Run UI Updates
});
});
A slightly modified version of @sidanmor 's code. The main point is, not every webpage is purely ASCII, user should be able to handle the decoding manually (even encode into base64)
function httpGet(url) {
return new Promise((resolve, reject) => {
const http = require('http'),
https = require('https');
let client = http;
if (url.toString().indexOf("https") === 0) {
client = https;
}
client.get(url, (resp) => {
let chunks = [];
// A chunk of data has been recieved.
resp.on('data', (chunk) => {
chunks.push(chunk);
});
// The whole response has been received. Print out the result.
resp.on('end', () => {
resolve(Buffer.concat(chunks));
});
}).on("error", (err) => {
reject(err);
});
});
}
(async(url) => {
var buf = await httpGet(url);
console.log(buf.toString('utf-8'));
})('https://httpbin.org/headers');
The trick is that you have to set it as position:fixed, but only after the user has scrolled past it.
This is done with something like this, attaching a handler to the window.scroll event
// Cache selectors outside callback for performance.
var $window = $(window),
$stickyEl = $('#the-sticky-div'),
elTop = $stickyEl.offset().top;
$window.scroll(function() {
$stickyEl.toggleClass('sticky', $window.scrollTop() > elTop);
});
This simply adds a sticky
CSS class when the page has scrolled past it, and removes the class when it's back up.
And the CSS class looks like this
#the-sticky-div.sticky {
position: fixed;
top: 0;
}
EDIT- Modified code to cache jQuery objects, faster now.
My code to convert array to Json
Code
List<String>a = new ArrayList<String>();
a.add("so 1");
a.add("so 2");
a.add("so 3");
JSONArray jray = new JSONArray(a);
System.out.println(jray.toString());
output
["so 1","so 2","so 3"]
The remove operation on a list is given a value to remove. It searches the list to find an item with that value and deletes the first matching item it finds. It is an error if there is no matching item, raises a ValueError.
>>> x = [1, 0, 0, 0, 3, 4, 5]
>>> x.remove(4)
>>> x
[1, 0, 0, 0, 3, 5]
>>> del x[7]
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
del x[7]
IndexError: list assignment index out of range
The del statement can be used to delete an entire list. If you have a specific list item as your argument to del (e.g. listname[7] to specifically reference the 8th item in the list), it'll just delete that item. It is even possible to delete a "slice" from a list. It is an error if there index out of range, raises a IndexError.
>>> x = [1, 2, 3, 4]
>>> del x[3]
>>> x
[1, 2, 3]
>>> del x[4]
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
del x[4]
IndexError: list assignment index out of range
The usual use of pop is to delete the last item from a list as you use the list as a stack. Unlike del, pop returns the value that it popped off the list. You can optionally give an index value to pop and pop from other than the end of the list (e.g listname.pop(0) will delete the first item from the list and return that first item as its result). You can use this to make the list behave like a queue, but there are library routines available that can provide queue operations with better performance than pop(0) does. It is an error if there index out of range, raises a IndexError.
>>> x = [1, 2, 3]
>>> x.pop(2)
3
>>> x
[1, 2]
>>> x.pop(4)
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
x.pop(4)
IndexError: pop index out of range

The query answered by sandip giri was the correct answer, here a similar example getting the maximum id (PresupuestoEtapaActividadHistoricoId), after calculate the maximum value(Base)
select *
from (
select PEAA.PresupuestoEtapaActividadId,
PEAH.PresupuestoEtapaActividadHistoricoId,
sum(PEAA.ValorTotalDesperdicioBase) as Base,
sum(PEAA.ValorTotalDesperdicioEjecucion) as Ejecucion
from hgc.PresupuestoActividadAnalisis as PEAA
inner join hgc.PresupuestoEtapaActividad as PEA
on PEAA.PresupuestoEtapaActividadId = PEA.PresupuestoEtapaActividadId
inner join hgc.PresupuestoEtapaActividadHistorico as PEAH
on PEA.PresupuestoEtapaActividadId = PEAH.PresupuestoEtapaActividadId
group by PEAH.PresupuestoEtapaActividadHistoricoId, PEAA.PresupuestoEtapaActividadId
) as t
where exists (
select 1
from (
select MAX(PEAH.PresupuestoEtapaActividadHistoricoId) as PresupuestoEtapaActividadHistoricoId
from hgc.PresupuestoEtapaActividadHistorico as PEAH
group by PEAH.PresupuestoEtapaActividadId
) as ti
where t.PresupuestoEtapaActividadHistoricoId = ti.PresupuestoEtapaActividadHistoricoId

A suggestion for how to do this such that:
.
public ActionResult Create(string returnUrl)
{
// If no return url supplied, use referrer url.
// Protect against endless loop by checking for empty referrer.
if (String.IsNullOrEmpty(returnUrl)
&& Request.UrlReferrer != null
&& Request.UrlReferrer.ToString().Length > 0)
{
return RedirectToAction("Create",
new { returnUrl = Request.UrlReferrer.ToString() });
}
// Do stuff...
MyEntity entity = GetNewEntity();
return View(entity);
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(MyEntity entity, string returnUrl)
{
try
{
// TODO: add create logic here
// If redirect supplied, then do it, otherwise use a default
if (!String.IsNullOrEmpty(returnUrl))
return Redirect(returnUrl);
else
return RedirectToAction("Index");
}
catch
{
return View(); // Reshow this view, with errors
}
}
You could use the redirect within the view like this:
<% if (!String.IsNullOrEmpty(Request.QueryString["returnUrl"])) %>
<% { %>
<a href="<%= Request.QueryString["returnUrl"] %>">Return</a>
<% } %>
You can do that with datetime.strptime()
Example:
>>> from datetime import datetime
>>> datetime.strptime('2012-02-10' , '%Y-%m-%d')
datetime.datetime(2012, 2, 10, 0, 0)
>>> _.isoweekday()
5
You can find the table with all the strptime
directive here.
To increment by 2 days if .isweekday() == 6
, you can use timedelta()
:
>>> import datetime
>>> date = datetime.datetime.strptime('2012-02-11' , '%Y-%m-%d')
>>> if date.isoweekday() == 6:
... date += datetime.timedelta(days=2)
...
>>> date
datetime.datetime(2012, 2, 13, 0, 0)
>>> date.strftime('%Y-%m-%d') # if you want a string again
'2012-02-13'
Googling gives me this:
Command A & Command B
Execute Command A, then execute Command B (no evaluation of anything)
Command A | Command B
Execute Command A, and redirect all its output into the input of Command B
Command A && Command B
Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B
Command A || Command B
Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B
If you are looking for a .NET Core version of @Dallas's answer, use the below.
Stream stream = null;
//This controls how many bytes to read at a time and send to the client
int bytesToRead = 10000;
// Buffer to read bytes in chunk size specified above
byte[] buffer = new Byte[bytesToRead];
// The number of bytes read
try
{
//Create a WebRequest to get the file
HttpWebRequest fileReq = (HttpWebRequest)HttpWebRequest.Create(@"file url");
//Create a response for this request
HttpWebResponse fileResp = (HttpWebResponse)fileReq.GetResponse();
if (fileReq.ContentLength > 0)
fileResp.ContentLength = fileReq.ContentLength;
//Get the Stream returned from the response
stream = fileResp.GetResponseStream();
// prepare the response to the client. resp is the client Response
var resp = HttpContext.Response;
//Indicate the type of data being sent
resp.ContentType = "application/octet-stream";
//Name the file
resp.Headers.Add("Content-Disposition", "attachment; filename=test.zip");
resp.Headers.Add("Content-Length", fileResp.ContentLength.ToString());
int length;
do
{
// Verify that the client is connected.
if (!HttpContext.RequestAborted.IsCancellationRequested)
{
// Read data into the buffer.
length = stream.Read(buffer, 0, bytesToRead);
// and write it out to the response's output stream
resp.Body.Write(buffer, 0, length);
//Clear the buffer
buffer = new Byte[bytesToRead];
}
else
{
// cancel the download if client has disconnected
length = -1;
}
} while (length > 0); //Repeat until no data is read
}
finally
{
if (stream != null)
{
//Close the input stream
stream.Close();
}
}
If don't like to add time picker, we can use just javascript for time part.
var dateObj=new Date();
var date = $.datepicker.formatDate('dd M yy', dateObj);
var time = dateObj.getHours()+":"+dateObj.getMinutes()+":"+dateObj.getSeconds();
console.log(date," ",time);
Just use the Form Paint method and draw every Picturebox on it, it allows transparency :
private void frmGame_Paint(object sender, PaintEventArgs e)
{
DoubleBuffered = true;
for (int i = 0; i < Controls.Count; i++)
if (Controls[i].GetType() == typeof(PictureBox))
{
var p = Controls[i] as PictureBox;
p.Visible = false;
e.Graphics.DrawImage(p.Image, p.Left, p.Top, p.Width, p.Height);
}
}
In Windows you can use a Powershell Script with CompareObject
compare-object -IncludeEqual -ExcludeDifferent -PassThru (get-content A.txt) (get-content B.txt)> MATCHING.txt | Out-Null #Find Matching Lines
CompareObject:
The @Aleks G OnKeyListener() works really well, but I ran it from MainActivity and so had to modify it slightly:
EditText searchBox = (EditText) findViewById(R.id.searchbox);
searchBox.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_ENTER) {
//if the enter key was pressed, then hide the keyboard and do whatever needs doing.
InputMethodManager imm = (InputMethodManager) MainActivity.this.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(searchBox.getApplicationWindowToken(), 0);
//do what you need on your enter key press here
return true;
}
return false;
}
});
I hope this helps anyone trying to do the same.
You entity is not correctly annotated, you must use the @javax.persistence.Entity
annotation. You can use the Hibernate extension @org.hibernate.annotations.Entity
to go beyond what JPA has to offer but the Hibernate annotation is not a replacement, it's a complement.
So change your code into:
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
public class Message {
...
}
Have a look at <openssl/pem.h>

Default log location (rhel) are
General messages:
/var/log/messages
Authentication messages:
/var/log/secure
Mail events:
/var/log/maillog
Check your /etc/syslog.conf
or /etc/syslog-ng.conf
(it depends on which of syslog facility you have installed)
Example:
$ cat /etc/syslog.conf
# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none /var/log/messages
# The authpriv file has restricted access.

# Log all the mail messages in one place.
mail.* /var/log/maillog
#For a start, use this simplified approach.

You can remove the existing options by using the empty
method, and then add your new options:
var option = $('<option></option>').attr("value", "option value").text("Text");
$("#selectId").empty().append(option);
If you have your new options in an object you can:
var newOptions = {"Option 1": "value1",
"Option 2": "value2",
"Option 3": "value3"
};
var $el = $("#selectId");
$el.empty(); // remove old options
$.each(newOptions, function(key,value) {
$el.append($("<option></option>")
.attr("value", value).text(key));
});
Edit: For removing the all the options but the first, you can use the :gt
selector, to get all the option
elements with index greater than zero and remove
them:
$('#selectId option:gt(0)').remove(); // remove all options, but not the first
I believe your question is to change only width of view dynamically, whereas above methods will change layout properties completely to new one, so I suggest to getLayoutParams() from view first, then set width on layoutParams, and finally set layoutParams to the view, so following below steps to do the same.
View view = findViewById(R.id.nutrition_bar_filled);
LayoutParams layoutParams = view.getLayoutParams();
layoutParams.width = newWidth;
view.setLayoutParams(layoutParams);

Try this:
.row > .span3 {
display: inline-block !important;
vertical-align: middle !important;
}
Fiddle: http://jsfiddle.net/EexYE/
You may need to add Diego's float: none !important;
also if span3 is floating and it interferes.
Fiddle: http://jsfiddle.net/D8McR/
In response to Alberto: if you fix the height of the row div, then to continue the vertical center alignment you'll need to set the line-height of the row to be the same as the pixel height of the row (ie. both to 300px in your case). If you'll do that you will notice that the child elements inherit the line-height, which is a problem in this case, so you will then need to set your line height for the span3s to whatever it should actually be (1.5 is the example value in the fiddle, or 1.5 x the font-size, which we did not change when we changed the line-height).

You would have to define operator+() for every data type you would want to concenate to the string, yet since operator<< is defined for most types, you should use std::stringstream.
Damn, beat by 50 seconds...
None of the other answers here worked for me, possibly from trying a combination of all of them. I was able to adapt this accepted answer to work with meld. This is now working for me with git 1.9.4, meld 3.14.0, and windows 8.1.
Edit ~/.gitconfig to look like:
[diff]
tool = meld
guitool = meld
[mergetool "meld"]
path = c:/Program Files (x86)/Meld/Meld.exe
[difftool "meld"]
path = c:/Program Files (x86)/Meld/Meld.exe
This is where you can find the answer in the job-dsl-plugin code.
Basically you can do something like this:

This way we can include html without encoding quotes, include variables from the DOM, and so on.
It is a powerful templating engine, we can use separate js files and use events to load the content in place, or even separate everything in chunks and call on demand:
let inject = document.createElement('script');
inject.src= '//....com/template/panel45.js';
more.appendChild(inject);

Swift 2.0 Xcode 7.0 beta 6 onwards uses joinWithSeparator()
instead of join()
:
var array = ["1", "2", "3"]
let stringRepresentation = array.joinWithSeparator("-") // "1-2-3"
joinWithSeparator
is defined as an extension on SequenceType
extension SequenceType where Generator.Element == String {
/// Interpose the `separator` between elements of `self`, then concatenate
/// the result. For example:
///
/// ["foo", "bar", "baz"].joinWithSeparator("-|-") // "foo-|-bar-|-baz"

A good option is to transform the number into a string and then split it.
// Decimal number
let number = 3.2;
// Convert it into a string
let string = number.toString();
// Split the dot
let array = string.split('.');
// Get both numbers
// The '+' sign transforms the string into a number again
let firstNumber = +array[0]; // 3
let secondNumber = +array[1]; // 2
let [firstNumber, secondNumber] = [+number.toString().split('.')[0], +number.toString().split('.')[1]];

Why do you set a status code in your request? and multiple declaration "Accept" with Accept:application/json,application/json,application/jsonrequest. just a statement is enough.
To show result till yesterday
WHERE DATE(date_time) < CURDATE()
To show results of 10 days
WHERE date_time < NOW() - INTERVAL 10 DAY
To show results before 10 days
WHERE DATE(date_time) < DATE(NOW() - INTERVAL 10 DAY)
These will work for you
You can find dates like this
SELECT DATE(NOW() - INTERVAL 11 DAY)
