Compiling the last answers into one:
If you're on Windows, use chocolatey:
choco install ffmpeg
If you are on Mac, use Brew:
brew install ffmpeg
If you are on a Debian Linux distribution, use apt:
sudo apt-get install ffmpeg
And make sure Youtube-dl is updated:
youtube-dl -U
It could be that one or two of your columns may have a factor in them, or what is more likely is that your columns may be formatted as factors. Please would you give str(col1) and str(col2) a try? That should tell you what format those columns are in.
I am unsure if you're trying to add the rows of a column to produce a new column or simply all of the numbers in both columns to get a single number.
If you are just trying to open a file, you could use app.open_resource()
. So reading a file would look something like
with app.open_resource('/static/path/yourfile'):
#code to read the file and do something
DATE TIME BASED INPUT
var dt1 = new Date("2019-1-8 11:19:16");
var dt2 = new Date("2019-1-8 11:24:16");
var diff =(dt2.getTime() - dt1.getTime()) ;
var hours = Math.floor(diff / (1000 * 60 * 60));
diff -= hours * (1000 * 60 * 60);
var mins = Math.floor(diff / (1000 * 60));
diff -= mins * (1000 * 60);
var response = {
status : 200,
Hour : hours,
Mins : mins
}
OUTPUT
{
"status": 200,
"Hour": 0,
"Mins": 5
}
I had the same problem with .c files that contained functions (not main()
of my program). For example, my header files were "fact.h" and "fact.c", and my main program was "main.c" so my commands were like this:
E:\proj> gcc -c fact.c
Now I had an object file of fact.c (fact.o). after that:
E:\proj>gcc -o prog.exe fact.o main.c
Then my program (prog.exe) was ready to use and worked properly. I think that -c
after gcc
was important, because it makes object files that can attach to make the program we need. Without using -c
, gcc ties to find main in your program and when it doesn't find it, it gives you this error.
I'm adding this answer because after researching the web, I ended up at this answer but still didn't know which subfolder of the IIS logs folder to look in.
If your server has multiple websites, you will need to know the IIS ID for the site. An easy way to get this in IIS is to simply click on the Sites folder in the left panel. The ID for each site is shown in the right panel.
Once you know the ID, let's call it n, the corresponding logs are in the W3SVCn subfolder of the IIS logs folder. So, if your website ID is 4, say, and the IIS logs are in the default location, then the logs are in this folder:
%SystemDrive%\inetpub\logs\LogFiles\W3SVC4
Acknowlegements:
html_entity_decode('エ', 0, 'UTF-8');
This works too. However the json_decode() solution is a lot faster (around 50 times).
I found another free site that will constantly ping your site called Unidler
Same as pingdom, but doesnt need to log in.
This is a generalization of the problem of "how do I find out how many bytes n bits will take? (A: (n bits + 7) / 8).
int RoundUp(int n, int roundTo)
{
// fails on negative? What does that mean?
if (roundTo == 0) return 0;
return ((n + roundTo - 1) / roundTo) * roundTo; // edit - fixed error
}
Two reasons, there may be more:
pip provides an uninstall
command
if an installation fails in the middle, pip will leave you in a clean state.
I'm using db2 7.1 and SQuirrel. This is the only query that worked for me.
select * from SYSIBM.tables where table_schema = 'my_schema' and table_type = 'BASE TABLE';
Modulo (mod, %) is the Remainder operator.
2%2 = 0 (2/2 = 1 remainder 0)
1%2 = 1 (1/2 = 0 remainder 1)
4%2 = 0 (4/2 = 2 remainder 0)
5%2 = 1 (5/2 = 2 remainder 1)
Here's a simple extension method that does what I need...
public static class EnumerableExtensions
{
public static IEnumerable<TKey> Distinct<T, TKey>(this IEnumerable<T> source, Func<T, TKey> selector)
{
return source.GroupBy(selector).Select(x => x.Key);
}
}
It's a shame they didn't bake a distinct method like this into the framework, but hey ho.
met% python -c 'import this' | grep 'only one'
There should be one-- and preferably only one --obvious way to do it.
If you want to always prune
when you fetch
, I can suggest to use Aliases.
Just type git config -e
to open your editor and change the configuration for a specific project and add a section like
[alias]
pfetch = fetch --prune
the when you fetch with git pfetch
the prune will be done automatically.
OK, so first of all the http://angular-ui.github.io/bootstrap/ has a <modal>
directive and the $dialog
service and both of those can be used to open modal windows.
The difference is that with the <modal>
directive content of a modal is embedded in a hosting template (one that triggers modal window opening). The $dialog
service is far more flexible and allow you to load modal's content from a separate file as well as trigger modal windows from any place in AngularJS code (this being a controller, a service or another directive).
Not sure what you mean exactly by "using JavaScript code" but assuming that you mean any place in AngularJS code the $dialog
service is probably a way to go.
It is very easy to use and in its simplest form you could just write:
$dialog.dialog({}).open('modalContent.html');
To illustrate that it can be really triggered by any JavaScript code here is a version that triggers modal with a timer, 3 seconds after a controller was instantiated:
function DialogDemoCtrl($scope, $timeout, $dialog){
$timeout(function(){
$dialog.dialog({}).open('modalContent.html');
}, 3000);
}
This can be seen in action in this plunk: http://plnkr.co/edit/u9HHaRlHnko492WDtmRU?p=preview
Finally, here is the full reference documentation to the $dialog
service described here:
https://github.com/angular-ui/bootstrap/blob/master/src/dialog/README.md
The ideal way is to use a dictionary that maps a word to it's count. But if you can't use that, you might want to use 2 lists - 1 storing the words, and the other one storing counts of words. Note that order of words and counts matters here. Implementing this would be hard and not very efficient.
Keystore Location
Each keytool command has a -keystore
option for specifying the name and location of the persistent keystore file for the keystore managed by keytool. The keystore is by default stored in a file named .keystore
in the user's home directory, as determined by the "user.home" system property. Given user name uName, the "user.home" property value defaults to
C:\Users\uName on Windows 7 systems
C:\Winnt\Profiles\uName on multi-user Windows NT systems
C:\Windows\Profiles\uName on multi-user Windows 95 systems
C:\Windows on single-user Windows 95 systems
Thus, if the user name is "cathy", "user.home" defaults to
C:\Users\cathy on Windows 7 systems
C:\Winnt\Profiles\cathy on multi-user Windows NT systems
C:\Windows\Profiles\cathy on multi-user Windows 95 systems
http://docs.oracle.com/javase/1.5/docs/tooldocs/windows/keytool.html
Do not use target="_blank"
Always use specific name for that window in my case meaningfulName
, in this case you save processor resource:
button.addEventListener('click', () => {
window.open('https://google.com', 'meaningfulName')
})
On this way when you click for example 10 times on button, browser will always re-render it in one new tab, instead of opening it in 10 different tabs which will consume much more resources.
You can read more about this on MDN
.
I had the similar issue and solved it by doing the below step.
Working Directory : It should point till the src folder of your project. C:\Users\name\Work\ProjectName\src
This is where I had issue and after correcting this, I could see the run option for that class.
1) For me that's the most simple way passing parameters to async task is like this
// To call the async task do it like this
Boolean[] myTaskParams = { true, true, true };
myAsyncTask = new myAsyncTask ().execute(myTaskParams);
Declare and use the async task like here
private class myAsyncTask extends AsyncTask<Boolean, Void, Void> {
@Override
protected Void doInBackground(Boolean...pParams)
{
Boolean param1, param2, param3;
//
param1=pParams[0];
param2=pParams[1];
param3=pParams[2];
....
}
2) Passing methods to async-task In order to avoid coding the async-Task infrastructure (thread, messagenhandler, ...) multiple times you might consider to pass the methods which should be executed in your async-task as a parameter. Following example outlines this approach. In addition you might have the need to subclass the async-task to pass initialization parameters in the constructor.
/* Generic Async Task */
interface MyGenericMethod {
int execute(String param);
}
protected class testtask extends AsyncTask<MyGenericMethod, Void, Void>
{
public String mParam; // member variable to parameterize the function
@Override
protected Void doInBackground(MyGenericMethod... params) {
// do something here
params[0].execute("Myparameter");
return null;
}
}
// to start the asynctask do something like that
public void startAsyncTask()
{
//
AsyncTask<MyGenericMethod, Void, Void> mytest = new testtask().execute(new MyGenericMethod() {
public int execute(String param) {
//body
return 1;
}
});
}
There is a solution even if you don't want to remove your local changes.
Just fix the unmerged files (by git add
or git remove
). Then do git pull
.
I found a post suggesting a solution for that. It's about to run:
svn resolve --accept working <YourPath>
which will claim the local version files as OK.
You can run it for single file or entire project catalogues.
This data is JSON! You can deserialize it using the built-in json
module if you're on Python 2.6+, otherwise you can use the excellent third-party simplejson
module.
import json # or `import simplejson as json` if on Python < 2.6
json_string = u'{ "id":"123456789", ... }'
obj = json.loads(json_string) # obj now contains a dict of the data
Try this query.. It uses the Analytic function SUM:
SELECT * FROM
(
SELECT SUM(1) OVER(PARTITION BY ctn_no) cnt, A.*
FROM table1 a
WHERE s_ind ='Y'
)
WHERE cnt > 2
Am not sure why you are identifying a record as a duplicate if the ctn_no repeats more than 2 times. FOr me it repeats more than once it is a duplicate. In this case change the las part of the query to WHERE cnt > 1
Based on my findings...
This Javascript error occurs when you execute button() on an element with a selector and try to use a function/method of button() with a different selector on the same element.
For example, here is the HTML:
<input type="submit" name="continue" id="mybuttonid" class="mybuttonclass" value="Continue" />
So you execute button() on it:
jQuery(document).ready(function() { jQuery('.mybuttonclass').button(); });
Then you try to disable it, this time not using the class as you initiated it but rather using the ID, then you'll get the error as this thread is titled:
jQuery(document).ready(function() { jQuery('#mybuttonid').button('option', 'disabled', true); });
So rather use the class again as you initiated it, that'll resolve the problem.
My answer might be late, but I guess it will help someone.

Based on the ObjectDumper of the LINQ samples I created a version that dumps each of the properties on its own line.
This Class Sample

public string Name { get; set; }
}
public class Address
{
public string Street { get; set; }
public int ZipCode { get; set; }
public string City { get; set; }

And to add multiple library files you can write as below:
INCLUDEPATH *= E:/DebugLibrary/VTK E:/DebugLibrary/VTK/Common E:/DebugLibrary/VTK/Filtering E:/DebugLibrary/VTK/GenericFiltering E:/DebugLibrary/VTK/Graphics E:/DebugLibrary/VTK/GUISupport/Qt E:/DebugLibrary/VTK/Hybrid E:/DebugLibrary/VTK/Imaging E:/DebugLibrary/VTK/IO E:/DebugLibrary/VTK/Parallel E:/DebugLibrary/VTK/Rendering E:/DebugLibrary/VTK/Utilities E:/DebugLibrary/VTK/VolumeRendering E:/DebugLibrary/VTK/Widgets E:/DebugLibrary/VTK/Wrapping

You can use the below code on your string and you will get the complete string without html part.
string title = "<b> Hulk Hogan's Celebrity Championship Wrestling <font color=\"#228b22\">[Proj # 206010]</font></b> (Reality Series, )".Replace(" ",string.Empty);
string s = Regex.Replace(title, "<.*?>", String.Empty);
You can index and use a negative sign to drop the 3rd column:
data[,-3]
Or you can list only the first 2 columns:
data[,c("c1", "c2")]
data[,1:2]
Don't forget the comma and referencing data frames works like this: data[row,column]
Here is an example of initializing a boolean[][]:
const n = 8; // or some dynamic value
const palindrome: boolean[][] = new Array(n)
.fill(false)
.map(() => new Array(n)
.fill(false));
my two cents about logic:
syntax is "old date" - :"new date", so:
SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:00', '2018-11-15 15:00:30')
gives 30,
SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:55', '2018-11-15 15:00:15')
gives: -40
The easiest way I've found to scroll a RecyclerView
is as follows:
// Define the Index we wish to scroll to.
final int lIndex = 0;
// Assign the RecyclerView's LayoutManager.
this.getRecyclerView().setLayoutManager(this.getLinearLayoutManager());
// Scroll the RecyclerView to the Index.
this.getLinearLayoutManager().smoothScrollToPosition(this.getRecyclerView(), new RecyclerView.State(), lIndex);
There are two options:
First
You can also use like is()
$('#dropDownId').is(':disabled');
Second
Using == true
by checking if the attributes value is disabled
. attr()
$('#dropDownId').attr('disabled');
whatever you feel fits better , you can use :)
Cheers!
Despite the question being about requests, I find this very easy to do with pycurl CURLOPT_TIMEOUT or CURLOPT_TIMEOUT_MS.
No threading or signaling required:
import pycurl
import StringIO
url = 'http://www.example.com/example.zip'
timeout_ms = 1000
raw = StringIO.StringIO()
c = pycurl.Curl()
c.setopt(pycurl.TIMEOUT_MS, timeout_ms) # total timeout in milliseconds
c.setopt(pycurl.WRITEFUNCTION, raw.write)
c.setopt(pycurl.NOSIGNAL, 1)
c.setopt(pycurl.URL, url)
c.setopt(pycurl.HTTPGET, 1)
try:
c.perform()
except pycurl.error:
traceback.print_exc() # error generated on timeout
pass # or just pass if you don't want to print the error
Firstly, double quote character is nothing special in regex - it's just another character, so it doesn't need escaping from the perspective of regex.
However, because java uses double quotes to delimit String constants, if you want to create a string in java with a double quote in it, you must escape them.
This code will test if your String matches:
if (str.matches("\".*\"")) {
// this string starts and end with a double quote
}
Note that you don't need to add start and end of input markers (^
and $
) in the regex, because matches()
requires that the whole input be matched to return true - ^
and $
are implied.
Matheus de Oliveira created handy functions for JSON CRUD operations in postgresql. They can be imported using the \i directive. Notice the jsonb fork of the functions if jsonb if your data type.

9.4 jsonb https://gist.github.com/inindev/2219dff96851928c2282
You should also look at new triggers.
MySQL doesn't show the table name in the error, so you're really left in a lurch. Here's a working example:
use test;
create table blah (id int primary key AUTO_INCREMENT, data varchar(100));
create table audit_blah (audit_id int primary key AUTO_INCREMENT, action enum('INSERT','UPDATE','DELETE'), id int, data varchar(100) null);
insert into audit_blah(action, id, data) values ('INSERT', 1, 'a');
select * from blah;
select * from audit_blah;
truncate table audit_blah;
delimiter //
/* I've commented out "id" below, so the insert fails with an ambiguous error: */
create trigger ai_blah after insert on blah for each row
begin
insert into audit_blah (action, /*id,*/ data) values ('INSERT', /*NEW.id,*/ NEW.data);
end;//
/* This insert is valid, but you'll get an exception from the trigger: */
insert into blah (data) values ('data1');
There were no real associative arrays in Javascript until 2015 (release of ECMAScript 6). Since then you can use the Map object as Robocat states. Look up the details in MDN. Example:
let map = new Map();
map.set('key', {'value1', 'value2'});
let values = map.get('key');
Without support for ES6 you can try using objects:
var x = new Object();
x["Key"] = "Value";
However with objects it is not possible to use typical array properties or methods like array.length. At least it is possible to access the "object-array" in a for-in-loop.
If TomCat is install. Perhaps it is not installed Java EE. Services-> plug-ins-> additional plug-ins-> in the search dial tomcat. and install the module java ee. then in the services, servers, add the tomcat server.
You're missing semi-colons after your javascript lines. Also, window.location
should have .href
or .replace
etc to redirect - See this post for more information.
echo '<script type="text/javascript">';
echo 'alert("review your answer");';
echo 'window.location.href = "index.php";';
echo '</script>';
For clarity, try leaving PHP tags for this:
?>
<script type="text/javascript">
alert("review your answer");
window.location.href = "index.php";
</script>
<?php
NOTE: semi colons on seperate lines are optional, but encouraged - however as in the comments below, PHP won't break lines in the first example here but will in the second, so semi-colons are required in the first example.
Since none of the answers have covered an asynchronous way of copying from one stream to another, here is a pattern that I've successfully used in a port forwarding application to copy data from one network stream to another. It lacks exception handling to emphasize the pattern.
const int BUFFER_SIZE = 4096;
static byte[] bufferForRead = new byte[BUFFER_SIZE];
static byte[] bufferForWrite = new byte[BUFFER_SIZE];
static Stream sourceStream = new MemoryStream();
static Stream destinationStream = new MemoryStream();
static void Main(string[] args)
{
// Initial read from source stream
sourceStream.BeginRead(bufferForRead, 0, BUFFER_SIZE, BeginReadCallback, null);
}
private static void BeginReadCallback(IAsyncResult asyncRes)
{
// Finish reading from source stream
int bytesRead = sourceStream.EndRead(asyncRes);
// Make a copy of the buffer as we'll start another read immediately
Array.Copy(bufferForRead, 0, bufferForWrite, 0, bytesRead);
// Write copied buffer to destination stream
destinationStream.BeginWrite(bufferForWrite, 0, bytesRead, BeginWriteCallback, null);
// Start the next read (looks like async recursion I guess)
sourceStream.BeginRead(bufferForRead, 0, BUFFER_SIZE, BeginReadCallback, null);
}
private static void BeginWriteCallback(IAsyncResult asyncRes)
{
// Finish writing to destination stream
destinationStream.EndWrite(asyncRes);
}
public enum NewEnum {
ONE("test"),
TWO("test");
private String s;
private NewEnum(String s) {
this.s = s);
}
public String getS() {
return this.s;
}
}
Session.Abandon()
http://msdn.microsoft.com/en-us/library/ms524310.aspx
Here is a little more detail on the HttpSessionState
object:
http://msdn.microsoft.com/en-us/library/system.web.sessionstate.httpsessionstate_members.aspx
Just for the sake of completeness based on the accepted answer and some others:
let items : [Any] = ["Hello", "World", 1]
for obj in items where obj is String {
// obj is a String. Do something with str
}
But you can also (compactMap
also "maps" the values which filter
doesn't):
items.compactMap { $0 as? String }.forEach{ /* do something with $0 */ ) }
And a version using switch
:
for obj in items {
switch (obj) {
case is Int:
// it's an integer
case let stringObj as String:
// you can do something with stringObj which is a String
default:
print("\(type(of: obj))") // get the type
}
}
But sticking to the question, to check if it's an array (i.e. [String]
):
let items : [Any] = ["Hello", "World", 1, ["Hello", "World", "of", "Arrays"]]
for obj in items {
if let stringArray = obj as? [String] {
print("\(stringArray)")
}
}
Or more generally (see this other question answer):
for obj in items {
if obj is [Any] {
print("is [Any]")
}
if obj is [AnyObject] {
print("is [AnyObject]")
}
if obj is NSArray {
print("is NSArray")

On Django 1.2, {{ form.data.field }} and {{ form.field.data }} are all OK, but not {{ form.field.value }}.
As others said, {{ form.field.value }} is Django 1.3+ only, but there's no specification in https://docs.djangoproject.com/en/1.3/topics/forms/. It can be found in https://docs.djangoproject.com/en/1.4/topics/forms/.
You don't need (shouldn't use) a function as far as I can tell. The stored procedure will return tabular data from any SELECT statements you include that return tabular data.
A stored proc does not use RETURN statements.
CREATE PROCEDURE name
AS
SELECT stuff INTO #temptbl1
.......
SELECT columns FROM #temptbln
I compared how the following three options perform:
import random, datetime
myDict = {}
for i in range( 10000000 ):
myDict[ i ] = random.randint( 0, 10000000 )
# OPTION 1
start = datetime.datetime.now()
sorted = []
for i in myDict:
sorted.append( ( i, myDict[ i ] ) )
sorted.sort( key = lambda x: x[1] )
print( sorted[0][0] )
end = datetime.datetime.now()
print( end - start )
# OPTION 2
start = datetime.datetime.now()
myDict_values = list( myDict.values() )
myDict_keys = list( myDict.keys() )
min_value = min( myDict_values )
print( myDict_keys[ myDict_values.index( min_value ) ] )
end = datetime.datetime.now()
print( end - start )
# OPTION 3
start = datetime.datetime.now()
print( min( myDict, key=myDict.get ) )
end = datetime.datetime.now()
print( end - start )
Sample output:
#option 1
236230
0:00:14.136808
#option 2
236230
0:00:00.458026
#option 3
236230
0:00:00.824048
I've used this all the time.
This is a good reading. Hope it helps. In terms of sorting you are concerning, I think it is for the merge operation in last step of Map. When map operation is done, and need to write the result to local disk, a multi-merge will be operated on the splits generated from buffer. And for a merge operation, sorting each partition in advanced is helpful.
Try this, but you can adjust frame size with bounds and edit title.
package co.form.Try;
import javax.swing.JFrame;
public class Form {
public static void main(String[] args) {
JFrame obj =new JFrame();
obj.setBounds(10,10,700,600);
obj.setTitle("Application Form");
obj.setResizable(false);
obj.setVisible(true);
obj.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
And if you want to somehow constrain the results here's a nice one:
$ git log --diff-filter=D --summary | sed -n '/^commit/h;/\/some_dir\//{G;s/\ncommit \(.*\)/ \1/gp}'
delete mode 100644 blah/some_dir/file1 d3bfbbeba5b5c1da73c432cb3fb61990bdcf6f64
delete mode 100644 blah/some_dir/file2 d3bfbbeba5b5c1da73c432cb3fb61990bdcf6f64
delete mode 100644 blah/some_dir/file3 9c89b91d8df7c95c6043184154c476623414fcb7
You'll get all files deleted from some_dir
(see the sed command) together with the commit number in which it happen. Any sed regex will do (I use this to find deleted file types, etc)
Use the tonumber
function. As in a = tonumber("10")
.
I just did some tests of the four options that I know about.
Measure-Command {$(1..1000) | Out-Null}
TotalMilliseconds : 76.211
Measure-Command {[Void]$(1..1000)}
TotalMilliseconds : 0.217
Measure-Command {$(1..1000) > $null}
TotalMilliseconds : 0.2478
Measure-Command {$null = $(1..1000)}
TotalMilliseconds : 0.2122
## Control, times vary from 0.21 to 0.24
Measure-Command {$(1..1000)}
TotalMilliseconds : 0.2141
So I would suggest that you use anything but Out-Null
due to overhead. The next important thing, to me, would be readability. I kind of like redirecting to $null
and setting equal to $null
myself. I use to prefer casting to [Void]
, but that may not be as understandable when glancing at code or for new users.
I guess I slightly prefer redirecting output to $null
.
Do-Something > $null
Edit
After stej's comment again, I decided to do some more tests with pipelines to better isolate the overhead of trashing the output.
Here are some tests with a simple 1000 object pipeline.
## Control Pipeline
Measure-Command {$(1..1000) | ?{$_ -is [int]}}
TotalMilliseconds : 119.3823
## Out-Null
Measure-Command {$(1..1000) | ?{$_ -is [int]} | Out-Null}
TotalMilliseconds : 190.2193
## Redirect to $null
Measure-Command {$(1..1000) | ?{$_ -is [int]} > $null}
TotalMilliseconds : 119.7923
In this case, Out-Null
has about a 60% overhead and > $null
has about a 0.3% overhead.
Addendum 2017-10-16: I originally overlooked another option with Out-Null
, the use of the -inputObject
parameter. Using this the overhead seems to disappear, however the syntax is different:
Out-Null -inputObject ($(1..1000) | ?{$_ -is [int]})
And now for some tests with a simple 100 object pipeline.
## Control Pipeline
Measure-Command {$(1..100) | ?{$_ -is [int]}}
TotalMilliseconds : 12.3566
## Out-Null
Measure-Command {$(1..100) | ?{$_ -is [int]} | Out-Null}
TotalMilliseconds : 19.7357
## Redirect to $null
Measure-Command {$(1..1000) | ?{$_ -is [int]} > $null}
TotalMilliseconds : 12.8527
Here again Out-Null
has about a 60% overhead. While > $null
has an overhead of about 4%. The numbers here varied a bit from test to test (I ran each about 5 times and picked the middle ground). But I think it shows a clear reason to not use Out-Null
.
If you want to use them as in swift 2, you can use these funcs:
For CGRectMake:
func CGRectMake(_ x: CGFloat, _ y: CGFloat, _ width: CGFloat, _ height: CGFloat) -> CGRect {
return CGRect(x: x, y: y, width: width, height: height)
}
For CGPointMake:
func CGPointMake(_ x: CGFloat, _ y: CGFloat) -> CGPoint {
return CGPoint(x: x, y: y)
}
For CGSizeMake:
func CGSizeMake(_ width: CGFloat, _ height: CGFloat) -> CGSize {
return CGSize(width: width, height: height)
}
Just put them outside any class and it should work. (Works for me at least)
If you happen to apply migrations already this may fix it.
Go to your Web.config and update your connection string based on your migration files.
Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-GigHub-201802102244201.mdf;Initial Catalog=aspnet-GigHub-201802102244201;
The datestrings should match the first numbers on your Migrations.
My case was rather embarrassing: I added a typescript binding for a JS library without adding the library itself.
So if you do:
npm install --save @types/lucene
Don't forget to do:
npm install --save lucene
Kinda obvious, but I just totally forgot and that cost me quite some time.
maybe you can try this: change jdk version. And I resolved this problem by change jdk from 1.6.0_37 to 1.6.0.45 . BR!
Following thing you should do before to run copy command if you facing some issue with copy command
public static IEnumerable<string> GetData()
{
yield return "1";
yield return "2";
yield return "3";
}
IEnumerable<string> m_oEnum = GetData();
Check this below code, it works
#define MAX_BYTE_RANGE 255
template <typename T>
class string
{
public:
typedef char *pointer;
typedef const char *const_pointer;
typedef __gnu_cxx::__normal_iterator<pointer, string> iterator;

{
}
size_t size() const
{
return length;
}
void operator=(const_pointer value)
{
if (value == nullptr)
throw std::invalid_argument("value cannot be null");
auto count = strlen(value);
if (count > 0)
_M_copy(value, count);
}
void operator=(const string &value)
{
if (value.length != 0)
_M_copy(value.buf, value.length);
}
iterator begin()
{
return iterator(buf);
}
iterator end()
{
return iterator(buf + length);
}
const_iterator begin() const
{
return const_iterator(buf);
}
const_iterator end() const
{
return const_iterator(buf + length);
}
const_pointer c_str() const
{
return buf;
}
~string()
{
}
private:
unsigned char length;
T buf[MAX_BYTE_RANGE];
void _M_copy(const_pointer value, size_t count)
{
memcpy(buf, value, count);
length = count;
}
};

Every time you used the mysql console, the version is shown.
mysql -u user
Successful console login shows the following which includes the mysql server version.
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1432
Server version: 5.5.9-log Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
You can also check the mysql server version directly by executing the following command:
mysql --version
You may also check the version information from the mysql console itself using the version variables:
mysql> SHOW VARIABLES LIKE "%version%";
Output will be something like this:
+-------------------------+---------------------+
| Variable_name | Value |
+-------------------------+---------------------+
| innodb_version | 1.1.5 |
| protocol_version | 10 |
| slave_type_conversions | |
| version | 5.5.9-log |
| version_comment | Source distribution |
| version_compile_machine | i386 |
| version_compile_os | osx10.4 |
+-------------------------+---------------------+
7 rows in set (0.01 sec)
You may also use this:
mysql> select @@version;
The STATUS command display version information as well.
mysql> STATUS
You can also check the version by executing this command:
mysql -v
It's worth mentioning that if you have encountered something like this:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/tmp/mysql.sock' (2)
you can fix it by:
sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock
I had the same problem and I solved in a slightly different way from the others. I am using angular 1.4.4.
In my case, I have a shell template that creates a CSS Bootstrap panel:
<div class="class-container panel panel-info">
<div class="panel-heading">
<h3 class="panel-title">{{title}} </h3>
</div>
<div class="panel-body">
<sp-panel-body panelbodytpl="{{panelbodytpl}}"></sp-panel-body>
</div>
</div>
I want to include panel body templates depending on the route.
angular.module('MyApp')
.directive('spPanelBody', ['$compile', function($compile){
return {
restrict : 'E',
scope : true,
link: function (scope, element, attrs) {
scope.data = angular.fromJson(scope.data);
element.append($compile('<ng-include src="\'' + scope.panelbodytpl + '\'"></ng-include>')(scope));
}
}
}]);
I then have the following template included when the route is #/students
:
<div class="students-wrapper">
<div ng-controller="StudentsIndexController as studentCtrl" class="row">
<div ng-repeat="student in studentCtrl.students" class="col-sm-6 col-md-4 col-lg-3">
<sp-panel
title="{{student.firstName}} {{student.middleName}} {{student.lastName}}"
panelbodytpl="{{'/student/panel-body.html'}}"
data="{{student}}"
></sp-panel>
</div>
</div>
</div>
The panel-body.html template as follows:
Date of Birth: {{data.dob * 1000 | date : 'dd MMM yyyy'}}
Sample data in the case someone wants to have a go:
var student = {
'id' : 1,
'firstName' : 'John',
'middleName' : '',
'lastName' : 'Smith',
'dob' : 1130799600,
'current-class' : 5
}

with open(csv_name_here, 'r', encoding="utf-16") as f:
I know I'm pretty late to the conversation, but I had this problem too. I think the issue was my company's firewall. My solution was to unplug from the network, connect to our open wireless and then force an update via Eclipse. This resolved everything.
Based on @davioooh answer. This code is worked for me.
ListObjectsRequest listObjectsRequest = new ListObjectsRequest().withBucketName("your-bucket")
.withPrefix("your/folder/path/").withDelimiter("/");
Hope you have key field is two tables.
UPDATE tblindiantime t

)
In my maven project this error occurs, after i closed my projects and reopens them. The dependencys wasn´t build correctly at that time. So for me the solution was just to update the Maven Dependencies of the projects!
The javadoc for File.delete()
public boolean delete()
Deletes the file or directory denoted by this abstract pathname. If this pathname >denotes a directory, then the directory must be empty in order to be deleted.
So a folder has to be empty or deleting it will fail. Your code currently fills the folder list with the top most folder first, followed by its sub folders. Since you iterrate through the list in the same way it will try to delete the top most folder before deleting its subfolders, this will fail.
Changing these line
for(String filePath : folderList) {
File tempFile = new File(filePath);
tempFile.delete();
}
to this
for(int i = folderList.size()-1;i>=0;i--) {
File tempFile = new File(folderList.get(i));
tempFile.delete();
}
should cause your code to delete the sub folders first.
The delete operation also returns false when it fails, so you can check this value to do some error handling if necessary.
<a href="deleteshare.php?did=<?php echo "$rowc[id]"; ?>&uid=<?php echo "$id";?>">DELETE</a>

Use this:
SELECT

This worked for me in newer browsers:

you could simply type :

I added substr to the test of https://stackoverflow.com/a/25472778/2386943 and that's the fastet way I could test (CentOS PHP 5.3.3, Ubuntu PHP 5.5.9) both with an i5.

Alternative solution (you can replace createElement with a your own element)
var mvar = $('.mbox').wrapAll(document.createElement('div')).closest('div').text();
console.log(mvar);
I found a better way of doing this
function genrateJSONEngine() {
var XLSX = require('xlsx');
var workbook = XLSX.readFile('test.xlsx');
var sheet_name_list = workbook.SheetNames;
sheet_name_list.forEach(function (y) {
var array = workbook.Sheets[y];
var first = array[0].join()
var headers = first.split(',');
var jsonData = [];
for (var i = 1, length = array.length; i < length; i++) {
var myRow = array[i].join();
var row = myRow.split(',');
var data = {};
for (var x = 0; x < row.length; x++) {
data[headers[x]] = row[x];
}
jsonData.push(data);
}
Login in with System Admin User Account and execute below SQL Procedure.
begin
dbms_xdb.sethttpport('Your Port Number');
end;
Then open the Browser and access the below URL
You can use some code like this, you can adjust a height and width as per your need
protected void button_Click(object sender, EventArgs e)
{
// open a pop up window at the center of the page.
ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "var Mleft = (screen.width/2)-(760/2);var Mtop = (screen.height/2)-(700/2);window.open( 'your_page.aspx', null, 'height=700,width=760,status=yes,toolbar=no,scrollbars=yes,menubar=no,location=no,top=\'+Mtop+\', left=\'+Mleft+\'' );", true);
}
I faced this issue, while connecting DB, the variable to connect to db was not defined.
Cause: php
tried to connect to the db with undefined variable for db host (localhost/127.0.0.1/... any other ip or domain) but failed to trace the domain.
Solution: Make sure the db host
is properly defined.
This will give you are simple print within a sql script:
select 'This is a comment' AS '';
Alternatively, this will add some dynamic data to your status update if used directly after an update
, delete
, or insert
command:
select concat ("Updated ", row_count(), " rows") as '';
i make this code it work fine but once form submit model button not open model again say e.preventdefault is not a function..
Use below code on any event that fire on submit form
$('.modal').removeClass('in');
$('.modal').attr("aria-hidden","true");
$('.modal').css("display", "none");
$('.modal-backdrop').remove();
$('body').removeClass('modal-open');
you can make this code more short..
if any body found solution for e.preventdefault let us know

You also can use graceful restart the apache server with service apache2 reload
or apachectl -k graceful
.
As the apache doc says:
The USR1 or graceful signal causes the parent process to advise the children to exit after their current request (or to exit immediately if they're not serving anything). The parent re-reads its configuration files and re-opens its log files. As each child dies off the parent replaces it with a child from the new generation of the configuration, which begins serving new requests immediately.
In .Net Core You can use
return new ForbidResult();
instead of
return Unauthorized();
which has the advantage to redirecting to the default unauthorized page (Account/AccessDenied) rather than giving a straight 401
to change the default location modify your startup.cs
services.AddAuthentication(options =>...)
.AddOpenIdConnect(options =>...)
.AddCookie(options =>
{
options.AccessDeniedPath = "/path/unauthorized";
})
fig.add_subplot(ROW,COLUMN,POSITION)
Examples
`fig.add_subplot(111)` #There is only one subplot or graph
`fig.add_subplot(211)` *and* `fig.add_subplot(212)`
There are total 2 rows,1 column therefore 2 subgraphs can be plotted. Its location is 1st. There are total 2 rows,1 column therefore 2 subgraphs can be plotted.Its location is 2nd
IMHO you should pay your attention to Robot.class
Still if you want to move the mouse pointer physically, you need to take different approach using Robot class
Point coordinates = driver.findElement(By.id("ctl00_portalmaster_txtUserName")).getLocation();
Robot robot = new Robot();
robot.mouseMove(coordinates.getX(),coordinates.getY()+120);
Webdriver provide document coordinates, where as Robot class is based on Screen coordinates, so I have added +120 to compensate the browser header.
Screen Coordinates: These are coordinates measured from the top left corner of the user's computer screen. You'd rarely get coordinates (0,0) because that is usually outside the browser window. About the only time you'd want these coordinates is if you want to position a newly created browser window at the point where the user clicked.
In all browsers these are in event.screenX
and event.screenY
.
Window Coordinates: These are coordinates measured from the top left corner of the browser's content area. If the window is scrolled, vertically or horizontally, this will be different from the top left corner of the document. This is rarely what you want.
In all browsers these are in event.clientX and event.clientY.
Document Coordinates: These are coordinates measured from the top left corner of the HTML Document. These are the coordinates that you most frequently want, since that is the coordinate system in which the document is defined.
More details you can get here
Hope this be helpful to you.
If you're not using auto-incrementing fields, you can achieve a similar result with something like the following:
insert into Customers (ID, FirstName, LastName)
select max(ID)+1, 'Barack', 'Obama' from Customers;
This will ensure there's no chance of a race condition which could be caused by someone else inserting into the table between your extraction of the maximum ID and your insertion of the new record.
This is using standard SQL, there are no doubt better ways to achieve it with specific DBMS' but they're not necessarily portable (something we take very seriously in our shop).
Without your seeing your data (you can use the output of dput(head(survey))
to show us) this is a shot in the dark:
survey <- data.frame(date=c("2012/07/26","2012/07/25"),tx_start=c("2012/01/01","2012/01/01"))
survey$date_diff <- as.Date(as.character(survey$date), format="%Y/%m/%d")-
as.Date(as.character(survey$tx_start), format="%Y/%m/%d")
survey
date tx_start date_diff

**Your Pyramid will be downwards like: **

}
for(var j=i; j>=1; j--){

}
console.log(str);

Your Pyramid will be upwards like :

for(var k=1; k<=n-i; k++){

}
console.log(str);
str = "";
}
}
stars(3);
There is another issue to be considered here. Some people expect that adding custom method to your repository will automatically expose them as REST services under '/search' link. This is unfortunately not the case. Spring doesn't support that currently.
This is 'by design' feature, spring data rest explicitly checks if method is a custom method and doesn't expose it as a REST search link:
private boolean isQueryMethodCandidate(Method method) {
return isQueryAnnotationPresentOn(method) || !isCustomMethod(method) && !isBaseClassMethod(method);
}
This is a qoute of Oliver Gierke:
This is by design. Custom repository methods are no query methods as they can effectively implement any behavior. Thus, it's currently impossible for us to decide about the HTTP method to expose the method under. POST would be the safest option but that's not in line with the generic query methods (which receive GET).
For more details see this issue: https://jira.spring.io/browse/DATAREST-206
With the latest versions of mock, you can use the really useful mock_open helper:
mock_open(mock=None, read_data=None)
A helper function to create a mock to replace the use of open. It works for open called directly or used as a context manager.
The mock argument is the mock object to configure. If None (the default) then a MagicMock will be created for you, with the API limited to methods or attributes available on standard file handles.
read_data is a string for the read method of the file handle to return. This is an empty string by default.
>>> from mock import mock_open, patch
>>> m = mock_open()
>>> with patch('{}.open'.format(__name__), m, create=True):
... with open('foo', 'w') as h:
... h.write('some stuff')
>>> m.assert_called_once_with('foo', 'w')
>>> handle = m()
>>> handle.write.assert_called_once_with('some stuff')
So if condition equals the value you want then the php document will run "include" and include will add that document to the current window for example:
`
<?php
$isARequest = true;
if ($isARequest){include('request.html');}/*So because $isARequest is true then it will include request.html but if its not a request then it will insert isNotARequest;*/
else if (!$isARequest) {include('isNotARequest.html')}
?>
`

The problem is that you set cipherText to empty string at every cycle iteration, the line
cipherText = ""
must be moved before the loop.
There are 2 methods that I can think of to check whether a string has all digits of not
Method 1(Using the built-in isdigit() function in python):-
>>>st = '12345'
>>>st.isdigit()
True
>>>st = '1abcd'
>>>st.isdigit()
False
Method 2(Performing Exception Handling on top of the string):-
st="1abcd"
try:
number=int(st)
print("String has all digits in it")
except:
print("String does not have all digits in it")
The output of the above code will be:
String does not have all digits in it
There's a function for that in SciPy. It's called Euclidean.
Example:
from scipy.spatial import distance
a = (1, 2, 3)
b = (4, 5, 6)
dst = distance.euclidean(a, b)
The Microsoft way is this:
MSDN: How to determine Which .NET Framework Versions Are Installed (which directs you to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\...
)
If you want foolproof that's another thing. I wouldn't worry about an xcopy of the framework folder. If someone did that I would consider the computer broken.
The most foolproof way would be to write a small program that uses each version of .NET and the libraries that you care about and run them.
For a no install method, PowerBasic is an excellent tool. It creates small no runtime required exe's. It could automate the checks described in the MS KB article above.
If you don't really like nested functions, you can also iterate over the keys:
myMap : Map<string, boolean>;
for(let key of myMap) {
if (myMap.hasOwnProperty(key)) {
console.log(JSON.stringify({key: key, value: myMap[key]}));
}
}
Note, you have to filter out the non-key iterations with the hasOwnProperty
, if you don't do this, you get a warning or an error.
Try this, it show the nearest points to provided coordinates (within 50 km). It works perfectly:
SELECT m.name,
m.lat, m.lon,
p.distance_unit
* DEGREES(ACOS(COS(RADIANS(p.latpoint))
* COS(RADIANS(m.lat))
* COS(RADIANS(p.longpoint) - RADIANS(m.lon))
+ SIN(RADIANS(p.latpoint))
* SIN(RADIANS(m.lat)))) AS distance_in_km
FROM <table_name> AS m
JOIN (
SELECT <userLat> AS latpoint, <userLon> AS longpoint,
50.0 AS radius, 111.045 AS distance_unit
) AS p ON 1=1
WHERE m.lat
BETWEEN p.latpoint - (p.radius / p.distance_unit)
AND p.latpoint + (p.radius / p.distance_unit)
AND m.lon BETWEEN p.longpoint - (p.radius / (p.distance_unit * COS(RADIANS(p.latpoint))))
AND p.longpoint + (p.radius / (p.distance_unit * COS(RADIANS(p.latpoint))))
ORDER BY distance_in_km
Just change <table_name>
. <userLat>
and <userLon>

A variant exists in which you can specify a prefix and suffix too.
See here for an implementation using foldLeft, which is much more verbose, but perhaps worth looking at for education's sake.
I'll answer for Windows guests. If you have VMware Tools installed, then the taskbar's notification area (near the clock) has an icon for VMware Tools. Double-click that and set your options.
If you don't have VMware Tools installed, you can still set the clock's option for internet time to sync with some NTP server. If your physical machine serves the NTP protocol to your guest machines then you can get that done with host-only networking. Otherwise you'll have to let your guests sync with a genuine NTP server out on the internet, for example time.windows.com.
Try this if you are on ubuntu:
sudo apt-get update
sudo apt-get install build-essential libpq-dev libssl-dev openssl libffi-dev zlib1g-dev
sudo apt-get install python3-pip python3.7-dev
sudo apt-get install python3.7
In case you don't have the repository and so it fires a not-found package you first have to install this:
sudo apt-get install -y software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update

Try this
function readRows() {
var sheet = SpreadsheetApp.getActiveSheet();
var rows = sheet.getDataRange();
var numRows = rows.getNumRows();
//var values = rows.getValues();
var Names = sheet.getRange("A2:A7");
var Name = [
Names.getCell(1, 1).getValue(),
Names.getCell(2, 1).getValue(),
.....
Names.getCell(5, 1).getValue()]
You can define arrays simply as follows, instead of allocating and then assigning.
var arr = [1,2,3,5]
Your initial error was because of the following line, and ones like it
var Name[0] = Name_cell.getValue();
Since Name
is already defined and you are assigning the values to its elements, you should skip the var
, so just
Name[0] = Name_cell.getValue();
Pro tip: For most issues that, like this one, don't directly involve Google services, you are better off Googling for the way to do it in javascript in general.
Using Linq you have many possibilities, here one without using lambdas:
//assuming list is a List<Customer> or something queryable...
var hasJohn = (from customer in list
where customer.FirstName == "John"
select customer).Any();
I know this is an old post but I thought I could share an alternative [not as robust, but simpler] approach to searching for a string in a table.
$("tr:contains(needle)");
//where needle is the text you are searching for.
For example, if you are searching for the text 'box', that would be:
$("tr:contains('box')");
This would return all the elements with this text. Additional criteria could be used to narrow it down if it returns multiple elements
WHILE is more flexible. FOR is more concise in those instances in which it applies.
FOR is great for loops which have a counter of some kind, like
for (int n=0; n<max; ++n)
You can accomplish the same thing with a WHILE, of course, as others have pointed out, but now the initialization, test, and increment are broken across three lines. Possibly three widely-separated lines if the body of the loop is large. This makes it harder for the reader to see what you're doing. After all, while "++n" is a very common third piece of the FOR, it's certainly not the only possibility. I've written many loops where I write "n+=increment" or some more complex expression.
FOR can also work nicely with things other than a counter, of course. Like
for (int n=getFirstElementFromList(); listHasMoreElements(); n=getNextElementFromList())
Etc.
But FOR breaks down when the "next time through the loop" logic gets more complicated. Consider:
initializeList();
while (listHasMoreElements())
{
n=getCurrentElement();
int status=processElement(n);
if (status>0)
{
skipElements(status);
advanceElementPointer();
}
else
{
n=-status;
findElement(n);
}
}
That is, if the process of advancing may be different depending on conditions encountered while processing, a FOR statement is impractical. Yes, sometimes you could make it work with a complicated enough expressions, use of the ternary ?: operator, etc, but that usually makes the code less readable rather than more readable.
In practice, most of my loops are either stepping through an array or structure of some kind, in which case I use a FOR loop; or are reading a file or a result set from a database, in which case I use a WHILE loop ("while (!eof())" or something of that sort).
I exited from my text editor that was accessing the project directories, then tried merging to the master branch and it worked.
If you use first answer, there is a problem with thumb. In chrome if you want the thumb to be larger than the track, then the box shadow overlaps the track with the height of the thumb.
Just sumup all these answers and wrote normally working slider with larger slider thumb: jsfiddle

const max = slider.max
const value = slider.value
slider.style.background = `linear-gradient(to right, red 0%, red ${(value-min)/(max-min)*100}%, #DEE2E6 ${(value-min)/(max-min)*100}%, #DEE2E6 100%)`
slider.oninput = function() {
this.style.background = `linear-gradient(to right, red 0%, red ${(this.value-this.min)/(this.max-this.min)*100}%, #DEE2E6 ${(this.value-this.min)/(this.max-this.min)*100}%, #DEE2E6 100%)`

You must use 'gem uninstall gem_name' to uninstall a gem.
Note that if you installed the gem system-wide (ie. sudo bundle install) then you may need to specify the binary directory using the -n option, to ensure binaries belonging to the gem are removed. For example
sudo gem uninstall gem_name -n /usr/lib/ruby/gems/1.9.1/bin
I also got the issue but after replacing existing one with the downloaded (from JCE) one resolved the issue. New crypto files provided unlimited strength.
In your User
model, add the following line in the User
class:
public $timestamps = true;
Now, whenever you save or update a user, Laravel will automatically update the created_at
and updated_at
fields.
Update:
If you want to set the created at manually you should use the date format Y-m-d H:i:s
. The problem is that the format you have used is not the same as Laravel uses for the created_at
field.
Update: Nov 2018 Laravel 5.6
"message": "Access level to App\\Note::$timestamps must be public",
Make sure you have the proper access level as well. Laravel 5.6 is public
.

for (int i = 0; i <= h-1; i++)
{
buttonArray[i] = new Button();
buttonArray[i].Size = new Size(20, 43);
buttonArray[i].Name= ""+i+"";
buttonArray[i].Click += button_Click;//function
buttonArray[i].Location = new Point(40, 20 + (i * 20));
panel1.Controls.Add(buttonArray[i]);
} }
"new" and "original" are different dicts, that's why you can update just one of them.. The items are shallow-copied, not the dict itself.

Here the sample code.try to resize the window. http://jsbin.com/wapono/13/edit
I messed around with this for awhile. Here was my scenario:
I have two types, metrics1 and metrics2, each with different properties:
type metrics1 = {
a: number;
b: number;
c: number;
}
type metrics2 = {
d: number;
e: number;
f: number;
}
At a point in my code, I created an object that is the intersection of these two types because this object will hold all of their properties:
const myMetrics: metrics1 & metrics2 = {
a: 10,
b: 20,
c: 30,
d: 40,
e: 50,
f: 60
};
Now, I need to dynamically reference the properties of that object. This is where we run into index signature errors. Part of the issue can be broken down based on compile-time checking and runtime checking. If I reference the object using a const, I will not see that error because TypeScript can check if the property exists during compile time:
const myKey = 'a';
console.log(myMetrics[myKey]); // No issues, TypeScript has validated it exists
If, however, I am using a dynamic variable (e.g. let), then TypeScript will not be able to check if the property exists during compile time, and will require additional help during runtime. That is where the following typeguard comes in:
function isValidMetric(prop: string, obj: metrics1 & metrics2): prop is keyof (metrics1 & metrics2) {
return prop in obj;
}
This reads as,"If the obj has the property prop then let TypeScript know that prop exists in the intersection of metrics1 & metrics2." Note: make sure you surround metrics1 & metrics2 in parentheses after keyof as shown above, or else you will end up with an intersection between the keys of metrics1 and the type of metrics2 (not its keys).
Now, I can use the typeguard and safely access my object during runtime:
let myKey:string = '';
myKey = 'a';
if (isValidMetric(myKey, myMetrics)) {
console.log(myMetrics[myKey]);
}
I had this concern when working on a Rails application with Docker.
My most preferred approach is to generally not use quotes. This includes not using quotes for:
${RAILS_ENV}
postgres-log:/var/log/postgresql
I, however, use double-quotes for integer
values that need to be converted to strings like:
version: "3.8"
"8080:8080"
However, for special cases like booleans
, floats
, integers
, and other cases, where using double-quotes for the entry values could be interpreted as strings
, please do not use double-quotes.
Here's a sample docker-compose.yml
file to explain this concept:
version: "3"
services:
traefik:
image: traefik:v2.2.1

Here a proper solution according to this post:
Create a directory
mkdir github-project-name
cd github-project-name
Set up a git repo
git init
git remote add origin <URL-link of the repo>
Configure your git-repo to download only specific directories
git config core.sparseCheckout true # enable this
Set the folder you like to be downloaded, e.g. you only want to download the doc directory from https://github.com/project-tree/master/doc
echo "/absolute/path/to/folder" > .git/info/sparse-checkout
E.g. if you only want to download the doc directory from your master repo https://github.com/project-tree/master/doc
, then your command is echo "doc" > .git/info/sparse-checkout
.
Download your repo as usual
git pull origin master
This is what you wanna do:
var oldSrc = 'http://example.com/smith.gif';
var newSrc = 'http://example.com/johnson.gif';
$('img[src="' + oldSrc + '"]').attr('src', newSrc);
As you have to use WITH (NOLOCK) for each table it might be annoying to write it in every FROM or JOIN clause. However it has a reason why it is called a "dirty" read. So you really should know when you do one, and not set it as default for the session scope. Why?
Forgetting a WITH (NOLOCK) might not affect your program in a very dramatic way, however doing a dirty read where you do not want one can make the difference in certain circumstances.
So use WITH (NOLOCK) if the current data selected is allowed to be incorrect, as it might be rolled back later. This is mostly used when you want to increase performance, and the requirements on your application context allow it to take the risk that inconsistent data is being displayed. However you or someone in charge has to weigh up pros and cons of the decision of using WITH (NOLOCK).
Righ Click on info.plist and select open as and then click on Source Code
Add this line in last of file before

and save file.
If you really want to prune your history of .gitignore
d files, first save .gitignore
outside the repo, e.g. as /tmp/.gitignore
, then run
git filter-branch --force --index-filter \
"git ls-files -i -X /tmp/.gitignore | xargs -r git rm --cached --ignore-unmatch -rf" \
--prune-empty --tag-name-filter cat -- --all
Notes:
git filter-branch --index-filter
runs in the .git
directory I think, i.e. if you want to use a relative path you have to prepend one more ../
first. And apparently you cannot use ../.gitignore
, the actual .gitignore
file, that yields a "fatal: cannot use ../.gitignore as an exclude file" for some reason (maybe during a git filter-branch --index-filter
the working directory is (considered) empty?)git ls-files -iX <(git show $(git hash-object -w .gitignore))
instead to avoid copying .gitignore
somewhere else, but that alone already returns an empty string (whereas cat <(git show $(git hash-object -w .gitignore))
indeed prints .gitignore
's contents as expected), so I cannot use <(git show $GITIGNORE_HASH)
in git filter-branch
....gitignore
-clean a specific branch, replace --all
in the last line with its name. The --tag-name-filter cat
might not work properly then, i.e. you'll probably not be able to directly transfer a single branch's tags properlyI didn't use DOS for - puh - feels like decades, but based on an old answer and my memories, the following should work (although I got no feedback, the answer was accepted, so it seems to work):
@echo off
REM init.txt should already exist
REM to create it:
REM COPY CON INIT.TXT
REM SET VARIABLE=^Z
REM ( press Ctrl-Z to generate ^Z )
REM
REM also the file "temp.txt" should exist.
REM add another "x" to a file:
echo x>>count.txt
REM count the lines in the file and put it in a tempfile:
type count.txt|find /v /c "" >temp.txt
REM join init.txt and temp.txt to varset.bat:
copy init.txt+temp.txt varset.bat
REM execute it to set %variable%:
call varset.bat
for %%i in (%variable%) do set numb=%%i
echo Count is: %numb%
REM just because I'm curious, does the following work? :
set numb2=%variable%
echo numb2 is now %var2%
if %numb%==250 goto :finished
echo another boot...
warmboot.exe
:finished
echo that was the last one.
In DOS, neither set /a
nor set /p
exist, so we have to work around that.
I think both for %%i in (%variable%) do set numb=%%i
and set numb2=%variable%
will work, but I can't verify.
WARNING: as there is no ">" or "<" comparison in DOS, you should delete the batchfile at the :finished
label (because it continues to increment and 251 is not equal 250 anymore)
(PS: the basic idea is from here. Thanks foxidrive. I knew, I knew it from StackOverflow but had a hard time to find it again)
Here is an example
#!/bin/bash
default='default_value'
value=${1:-$default}
echo "value: [$value]"
save this as script.sh and make it executable. run it without params
./script.sh
> value: [default_value]
run it with param
./script.sh my_value
> value: [my_value]
It seems that the trend in Android now is to use a Constraint layout. Although it is simple enough to center a view using a RelativeLayout
(as other answers have shown), the ConstraintLayout
is more powerful than the RelativeLayout
for more complex layouts. So it is worth learning how do do now.
To center a view, just drag the handles to all four sides of the parent.
Also, please make sure you installed the correct version of apache on your computer. For example, not install a x86 on a 64bit system. Vice versa.

It improves readability of your code, provides extra type safety and save some compiler efforts.
Say you want to print each element of a container, you can use the following code without template template parameter
template <typename T> void print_container(const T& c)
{
for (const auto& v : c)
{
std::cout << v << ' ';
}
std::cout << '\n';
}
or with template template parameter
template< template<typename, typename> class ContainerType, typename ValueType, typename AllocType>
void print_container(const ContainerType<ValueType, AllocType>& c)
{
for (const auto& v : c)
{
std::cout << v << ' ';
}
std::cout << '\n';
}
Assume you pass in an integer say print_container(3)
. For the former case, the template will be instantiated by the compiler which will complain about the usage of c
in the for loop, the latter will not instantiate the template at all as no matching type can be found.
Generally speaking, if your template class/function is designed to handle template class as template parameter, it is better to make it clear.
echo '<p class="paragraph'.$i.'"></p>';
You have asked two questions, one in the title about the difference between PNG8 and PNG24, which has received a few answers, namely that PNG24 has 8-bit red, green, and blue channels, and PNG-8 has a single 8-bit index into a palette. Naturally, PNG24 usually has a larger filesize than PNG8. Furthermore, PNG8 usually means that it is opaque or has only binary transparency (like GIF); it's defined that way in ImageMagick/GraphicsMagick.
This is an answer to the other one, "I would like to know that if I use either type in my html page, will there be any error? Or is this only quality matter?"
You can put either type on an HTML page and no, this won't cause an error; the files should all be named with the ".png" extension and referred to that way in your HTML. Years ago, early versions of Internet Explorer would not handle PNG with an alpha channel (PNG32) or indexed-color PNG with translucent pixels properly, so it was useful to convert such images to PNG8 (indexed-color with binary transparency conveyed via a PNG tRNS chunk) -- but still use the .png extension, to be sure they would display properly on IE. I think PNG24 was always OK on Internet Explorer because PNG24 is either opaque or has GIF-like single-color transparency conveyed via a PNG tRNS chunk.
The names PNG8 and PNG24 aren't mentioned in the PNG specification, which simply calls them all "PNG". Other names, invented by others, include
There are many more possible combinations including grayscale with 1, 2, 4, 8, or 16-bit samples and indexed PNG with 1, 2, or 4-bit samples (and any of those with transparent or translucent pixels), but those don't have special names.
So You want to write data to a file, but only if it doesn’t already exist?.
This problem is easily solved by using the little-known x mode to open() instead of the usual w mode. For example:
>>> with open('somefile', 'wt') as f:
... f.write('Hello\n')
...
>>> with open('somefile', 'xt') as f:
... f.write('Hello\n')
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
FileExistsError: [Errno 17] File exists: 'somefile'
>>>
If the file is binary mode, use mode xb instead of xt.
Here is an example:
#include"stdio.h"
#include"conio.h"
void main()
{
int rm, vivek;
clrscr();
printf("Enter any numbers\t(E.g., 1, 2, 5");
scanf("%d", &rm); // rm = 5(0101) << 2 (two step add zero's), so the value is 10100
printf("This left shift value%d=%d", rm, rm<<4);
printf("This right shift value%d=%d", rm, rm>>2);
getch();
}
You can use the git merge-base
command to find the latest common commit between the two branches. If that commit is the same as your branch head, then the branch has been completely merged.
Note that
git branch -d
does this sort of thing already because it will refuse to delete a branch that hasn't already been completely merged.
Here's a simple way using ngModel
(final Angular 2)
<!-- my.component.html -->
<div class="form-group">
<label for="options">Options:</label>
<div *ngFor="let option of options">
<label>
<input type="checkbox"
name="options"
value="{{option.value}}"
[(ngModel)]="option.checked"/>
{{option.name}}
</label>
</div>
</div>
// my.component.ts
@Component({ moduleId:module.id, templateUrl:'my.component.html'})
export class MyComponent {
options = [
{name:'OptionA', value:'1', checked:true},
{name:'OptionB', value:'2', checked:false},
{name:'OptionC', value:'3', checked:true}
]
get selectedOptions() { // right now: ['1','3']
return this.options
.filter(opt => opt.checked)
.map(opt => opt.value)
}
}
Try it ..
UPDATE PRODUCTION a
SET (name, count) = (
SELECT name, count
FROM STAGING b
WHERE a.ID = b.ID)
WHERE EXISTS (SELECT 1
FROM STAGING b
WHERE a.ID=b.ID
);
Or if one want to use lambda
function in the apply
function:
data['Revenue']=data['Revenue'].apply(lambda x:float(x.replace("$","").replace(",", "").replace(" ", "")))
This answer is no longer the best answer ... see the flexbox answer below instead!
To get it perfectly centered (as mentioned in david's answer) you need to add a negative top margin. If you know (or force) there to only be a single line of text, you can use:
margin-top: -0.5em;
for example:
http://jsfiddle.net/45MHk/623/
//CSS:
html, body, div {
height: 100%;
}
#parent
{
position:relative;
border: 1px solid black;
}
#child
{
position: absolute;
top: 50%;
/* adjust top up half the height of a single line */
margin-top: -0.5em;
/* force content to always be a single line */
overflow: hidden;
white-space: nowrap;
width: 100%;
text-overflow: ellipsis;
}
//HTML:
<div id="parent">
<div id="child">Text that is suppose to be centered</div>
</div>?
The originally accepted answer will not vertically center on the middle of the text (it centers based on the top of the text). So, if you parent is not very tall, it will not look centered at all, for example:
//CSS:
#parent
{
position:relative;
height: 3em;
border: 1px solid black;
}
#child
{
position: absolute;
top: 50%;
}?
//HTML:
<div id="parent">
<div id="child">Text that is suppose to be centered</div>
</div>?
You may consider using configure_file with the COPYONLY
option:
configure_file(<input> <output> COPYONLY)
Unlike file(COPY ...)
it creates a file-level dependency between input and output, that is:
If the input file is modified the build system will re-run CMake to re-configure the file and generate the build system again.
Its also important to note that you will lose the chronological stack trace of the exception if you you have a void return type on an async method. I would recommend returning Task as follows. Going to make debugging a whole lot easier.
public async Task DoFoo()
{
try
{
return await Foo();
}
catch (ProtocolException ex)
{
/* Exception with chronological stack trace */
}
}
Besides syntactical differences, many people also prefer using void function(void)
for pracitical reasons:
If you're using the search function and want to find the implementation of the function, you can search for function(void)
, and it will return the prototype as well as the implementation.
If you omit the void
, you have to search for function()
and will therefore also find all function calls, making it more difficult to find the actual implementation.
"All I want to do is join the tables and then group all the employees in a particular location together."
It sounds like what you want is for the output of the SQL statement to list every employee in the company, but first all the people in the Anaheim office, then the people in the Buffalo office, then the people in the Cleveland office (A, B, C, get it, obviously I don't know what locations you have).
In that case, lose the GROUP BY statement. All you need is ORDER BY loc.LocationID
You did not include jquery library. In jsfiddle its already there. Just include this line in your head section.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
Try:
Select * Into <DestinationTableName> From <SourceTableName> Where 1 = 2
Note that this will not copy indexes, keys, etc.
If you want to copy the entire structure, you need to generate a Create Script of the table. You can use that script to create a new table with the same structure. You can then also dump the data into the new table if you need to.
If you are using Enterprise Manager, just right-click the table and select copy to generate a Create Script.
Extending on what 'Happytime harry' said, be sure to use the .data() jquery function to store the timeout id. This is so that you can retrieve the timeout id very easily when the 'mouseenter' is triggered on that same element later, allowing you to eliminate the trigger for your tooltip to disappear.
ngOnInit()
is called right after the directive's data-bound properties have been checked for the first time, and before any of its children have been checked. It is invoked only once when the directive is instantiated.
ngAfterViewInit()
is called after a component's view, and its children's views, are created. Its a lifecycle hook that is called after a component's view has been fully initialized.
You could try using the system stored procedure sp_help_job. This returns information on the job, its steps, schedules and servers. For example
EXEC msdb.dbo.sp_help_job @Job_name = 'Your Job Name'
SQL Books Online should contain lots of information about the records it returns.
For returning information on multiple jobs, you could try querying the following system tables which hold the various bits of information on the job
Their names are fairly self-explanatory (apart from SysJobServers which hold information on when the job last run and the outcome).
Again, information on the fields can be found at MSDN. For example, check out the page for SysJobs
Just in case somebody else stumbles across this problem, I inherited an older CodeIgniter project and had a lot of trouble getting it to install.
I wasted a ton of time trying to create a local installation of the site and tried everything. In the end, the solution was simple.
The problem is that older CodeIgniter versions (like 1.7 and below), don't work with PHP 5.3. The solution is to switch to PHP 5.2 or something older.
var d1 = Date.parse("2012-11-01");
var d2 = Date.parse("2012-11-04");
if (d1 < d2) {
alert ("Error!");
}
I think the function you're looking for is MONTH(date)
. You'll probably want to use 'YEAR' too.
Let's assume you have a table named things
that looks something like this:
id happend_at
-- ----------------
1 2009-01-01 12:08
2 2009-02-01 12:00
3 2009-01-12 09:40
4 2009-01-29 17:55
And let's say you want to execute to find all the records that have a happened_at
during the month 2009/01 (January 2009). The SQL query would be:
SELECT id FROM things
WHERE MONTH(happened_at) = 1 AND YEAR(happened_at) = 2009
Which would return:
id
---
1
3
4
Set the DataGridView property
gridView1.AutoGenerateColumns = true;
And make sure the list of objects your are binding, those object properties should be public.
This is easy, at least if you want a 1-based, 1D or 2D variant array:
Sub StuffVArr()
Dim v() As Variant
Dim q() As Variant
v = Evaluate("=IF(ISERROR(A1:K1), 13, 13)")
q = Evaluate("=IF(ISERROR(A1:G48), 13, 13)")
End Sub
Byte arrays also aren't too bad:
Private Declare Sub FillMemory Lib "kernel32" Alias "RtlFillMemory" _
(dest As Any, ByVal size As Long, ByVal fill As Byte)
Sub StuffBArr()
Dim i(0 To 39) As Byte
Dim j(1 To 2, 5 To 29, 2 To 6) As Byte
FillMemory i(0), 40, 13
FillMemory j(1, 5, 2), 2 * 25 * 5, 13
End Sub
You can use the same method to fill arrays of other numeric data types, but you're limited to only values which can be represented with a single repeating byte:
Sub StuffNArrs()
Dim i(0 To 4) As Long
Dim j(0 To 4) As Integer
Dim u(0 To 4) As Currency
Dim f(0 To 4) As Single
Dim g(0 To 4) As Double
FillMemory i(0), 5 * LenB(i(0)), &HFF 'gives -1
FillMemory i(0), 5 * LenB(i(0)), &H80 'gives -2139062144
FillMemory i(0), 5 * LenB(i(0)), &H7F 'gives 2139062143
FillMemory j(0), 5 * LenB(j(0)), &HFF 'gives -1
FillMemory u(0), 5 * LenB(u(0)), &HFF 'gives -0.0001
FillMemory f(0), 5 * LenB(f(0)), &HFF 'gives -1.#QNAN
FillMemory f(0), 5 * LenB(f(0)), &H80 'gives -1.18e-38
FillMemory f(0), 5 * LenB(f(0)), &H7F 'gives 3.40e+38
FillMemory g(0), 5 * LenB(g(0)), &HFF 'gives -1.#QNAN
End Sub
If you want to avoid a loop in other situations, it gets even hairier. Not really worth it unless your array is 50K entries or larger. Just set each value in a loop and you'll be fast enough, as I talked about in an earlier answer.
If you want to set typeface to all the TextViews in the entire Activity you can use something like this:
public static void setTypefaceToAll(Activity activity)
{
View view = activity.findViewById(android.R.id.content).getRootView();
setTypefaceToAll(view);
}
public static void setTypefaceToAll(View view)
{
if (view instanceof ViewGroup)
{
ViewGroup g = (ViewGroup) view;
int count = g.getChildCount();
for (int i = 0; i < count; i++)
setTypefaceToAll(g.getChildAt(i));
}
else if (view instanceof TextView)
{
TextView tv = (TextView) view;
setTypeface(tv);
}
}
public static void setTypeface(TextView tv)
{
TypefaceCache.setFont(tv, TypefaceCache.FONT_KOODAK);
}
And the TypefaceCache:
import java.util.TreeMap;
import android.graphics.Typeface;
import android.widget.TextView;
public class TypefaceCache {
//Font names from asset:
public static final String FONT_ROBOTO_REGULAR = "fonts/Roboto-Regular.ttf";
public static final String FONT_KOODAK = "fonts/Koodak.ttf";
private static TreeMap<String, Typeface> fontCache = new TreeMap<String, Typeface>();
public static Typeface getFont(String fontName) {
Typeface tf = fontCache.get(fontName);
if(tf == null) {
try {
tf = Typeface.createFromAsset(MyApplication.getAppContext().getAssets(), fontName);
}
catch (Exception e) {
return null;
}
fontCache.put(fontName, tf);
}
return tf;
}
public static void setFont(TextView tv, String fontName)
{
tv.setTypeface(getFont(fontName));
}
}
"Best" as in pure performance? or performance AND readability?
Pure performance "best" is this, which uses a cache and the ++prefix operator (my data: http://jsperf.com/caching-array-length/189)
for (var i = 0, len = myArray.length; i < len; ++i) {
// blah blah
}
I would argue that the cache-less for-loop is the best balance in execution time and programmer reading time. Every programmer that started with C/C++/Java won't waste a ms having to read through this one
for(var i=0; i < arr.length; i++){
// blah blah
}
A quick hack I used which works well:
const monthNumber = 8;_x000D_
const yearNumber = 2018;_x000D_
const date = `${['Jan', 'Feb', 'Mar', 'Apr',_x000D_
'May', 'Jun', 'Jul', 'Aug',_x000D_
'Sep', 'Oct', 'Nov', 'Dec'][monthNumber - 1]_x000D_
} ${yearNumber}`;_x000D_
_x000D_
console.log(date);
_x000D_
There is no way to automatically set CMAKE_PREFIX_PATH
in a way you want. I see following ways to solve this problem:
Put all libraries files in the same dir. That is, include/
would contain headers for all libs, lib/
- binaries, etc. FYI, this is common layout for most UNIX-like systems.
Set global environment variable CMAKE_PREFIX_PATH
to D:/develop/cmake/libs/libA;D:/develop/cmake/libs/libB;...
. When you run CMake, it would aautomatically pick up this env var and populate it's own CMAKE_PREFIX_PATH
.
Write a wrapper .bat script, which would call cmake
command with -D CMAKE_PREFIX_PATH=...
argument.
Also, you can use or create and share Visual Studio color schemes: https://studiostyl.es/
In AndroidManifest.xml -> inside the activity which you want to use, add the following:
android:theme="@style/Theme.AppCompat.Light.NoActionBar"
//this is for hiding action bar
and in MainActivity.java -> inside onCreate() method, add the following :
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//this is for hiding status bar
Numeric.product
( or
reduce(lambda x,y:x*y,[3,4,5])
)
Here's the code I ended up writing. This code assumes that a point is defined in the form of {x:5, y:7}
. Note that this is not the absolute most efficient way, but it's the simplest and easiest-to-understand code that I could come up with.
// a, b, and c in the code below are all points
function distance(a, b)
{
var dx = a.x - b.x;
var dy = a.y - b.y;
return Math.sqrt(dx*dx + dy*dy);
}
function Segment(a, b)
{
var ab = {
x: b.x - a.x,
y: b.y - a.y
};
var length = distance(a, b);
function cross(c) {
return ab.x * (c.y-a.y) - ab.y * (c.x-a.x);
};
this.distanceFrom = function(c) {
return Math.min(distance(a,c),
distance(b,c),
Math.abs(cross(c) / length));
};
}
You really want to use at. It is exactly made for this purpose.
echo /usr/bin/the_command options | at now + 1 day
However if you don't have at, or your hosting company doesn't provide access to it, you could make a self-deleting cron entry.
Sadly, this will remove all your cron entries. However, if you only have one, this is fine.
0 0 2 12 * crontab -r ; /home/adm/bin/the_command options
The command crontab -r
removes your crontab entry. Luckily the rest of the command line will still execute.
WARNING: This is dangerous! It removes ALL cron entries. If you have many, this will remove them all, not just the one that has the "crontab -r" line!
As explained above not just the db datatype it will also affect the view that will be generated if you are scaffolding. string will generate a text_field text will generate a text_area
Also check for including jQuery, followed by some components/other libraries (like jQuery UI) and then accidentially including jQuery again - this will redefine jQuery and drop the component helpers (like .datepicker) off the instance.
The problem is that a link to a closed file works with index( but not with index(indirect(
It seems to me that it is a programming issue of the index function. I solved it with a if clause row
C2=sheetname
if(c2=Sheet1,index(sheet1....),if(C2="Sheet2",index(sheet2....
I did it over five sheets, it's a long formula, but does what I need.
Besides Console.OutputEncoding = System.Text.Encoding.UTF8;
for some characters you need to install extra fonts (ie. Chinese).
In Windows 10 first go to Region & language settings and install support for required language:
After that you can go to Command Prompt Proporties (or Defaults if you like) and choose some font that supports your language (like KaiTi in Chinese case):
First off, you have to specify you wish to use Document Literal style:
$client = new SoapClient(NULL, array(
'location' => 'https://example.com/path/to/service',
'uri' => 'http://example.com/wsdl',
'trace' => 1,
'use' => SOAP_LITERAL)
);
Then, you need to transform your data into a SoapVar; I've written a simple transform function:
function soapify(array $data)
{
foreach ($data as &$value) {
if (is_array($value)) {
$value = soapify($value);
}
}
return new SoapVar($data, SOAP_ENC_OBJECT);
}
Then, you apply this transform function onto your data:
$data = soapify(array(
'Acquirer' => array(
'Id' => 'MyId',
'UserId' => 'MyUserId',
'Password' => 'MyPassword',
),
));
Finally, you call the service passing the Data parameter:
$method = 'Echo';
$result = $client->$method(new SoapParam($data, 'Data'));
You need to specify the minimum width of the field.
String.format("%" + numberOfSpaces + "s", "");
Why do you want to generate a String of spaces of a certain length.
If you want a column of this length with values then you can do:
String.format("%" + numberOfSpaces + "s", "Hello");
which gives you numberOfSpaces-5 spaces followed by Hello. If you want Hello to appear on the left then add a minus sign in before numberOfSpaces.
I'd rather recommend you to use Volley to make GET, PUT, POST... requests.
First, add dependency in your gradle file.
compile 'com.he5ed.lib:volley:android-cts-5.1_r4'
Now, use this code snippet to make requests.
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
StringRequest postRequest = new StringRequest( com.android.volley.Request.Method.POST, mURL,
new Response.Listener<String>()
{
@Override
public void onResponse(String response) {
// response
Log.d("Response", response);
}
},
new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error) {
// error
Log.d("Error.Response", error.toString());
}
}
) {
@Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String>();
//add your parameters here as key-value pairs
params.put("username", username);
params.put("password", password);
return params;
}
};
queue.add(postRequest);
Came across this looking for something else.
While the post looks fairly old, the easiest solution in bash is illustrated below (at least bash 4) using set -- "${@:#}"
where # is the starting number of the array element we want to preserve forward:
#!/bin/bash
someVar="${1}"
someOtherVar="${2}"
set -- "${@:3}"
input=${@}
[[ "${input[*],,}" == *"someword"* ]] && someNewVar="trigger"
echo -e "${someVar}\n${someOtherVar}\n${someNewVar}\n\n${@}"
Basically, the set -- "${@:3}"
just pops off the first two elements in the array like perl's shift and preserves all remaining elements including the third. I suspect there's a way to pop off the last elements as well.
To convert an int
ASCII value to character you can also use:
int asciiValue = 65;
char character = char(asciiValue);
cout << character; // output: A
cout << char(90); // output: Z
If your database supports arrays, you can also implement a lineage column or materialized path as an array of parent ids.
Specifically with Postgres you can then use the set operators to query the hierarchy, and get excellent performance with GIN indices. This makes finding parents, children, and depth pretty trivial in a single query. Updates are pretty manageable as well.
I have a full write up of using arrays for materialized paths if you're curious.
Yet another possible solution for you. I was having similar problems connecting to gmail via IMAP. After trying all the solutions that I came across that you will read about here and elsewhere on SO (eg. enable IMAP, enable less secure access to your mail, using https://accounts.google.com/b/0/displayunlockcaptcha and so on), I actually set up a new gmail account once more.
In my original test, the first gmail account I had created, I had connected to my main gmail account. This resulted in erratic behaviour where the wrong account was being referenced by google. For example, running https://accounts.google.com/b/0/displayunlockcaptcha opened up my main account rather than the one I had created for the purpose.
So when I created a new account and did not connect it to my main account, after following all the appropriate steps as above, I found that it worked fine!
I haven't yet confirmed this (ie. reproduced), but it apparently did it for me...hope it helps.

Threading is another possible solution. Although the Celery based solution is better for applications at scale, if you are not expecting too much traffic on the endpoint in question, threading is a viable alternative.
This solution is based on Miguel Grinberg's PyCon 2016 Flask at Scale presentation, specifically slide 41 in his slide deck. His code is also available on github for those interested in the original source.
From a user perspective the code works as follows:
To convert an api call to a background task, simply add the @async_api decorator.
Here is a fully contained example:
from flask import Flask, g, abort, current_app, request, url_for
from werkzeug.exceptions import HTTPException, InternalServerError
from flask_restful import Resource, Api
from datetime import datetime
from functools import wraps
import threading
import time
import uuid
tasks = {}
app = Flask(__name__)
api = Api(app)
@app.before_first_request
def before_first_request():
"""Start a background thread that cleans up old tasks."""
def clean_old_tasks():
"""
This function cleans up old tasks from our in-memory data structure.
"""
global tasks
while True:
# Only keep tasks that are running or that finished less than 5
# minutes ago.
five_min_ago = datetime.timestamp(datetime.utcnow()) - 5 * 60
tasks = {task_id: task for task_id, task in tasks.items()
if 'completion_timestamp' not in task or task['completion_timestamp'] > five_min_ago}
time.sleep(60)
if not current_app.config['TESTING']:
thread = threading.Thread(target=clean_old_tasks)
thread.start()
def async_api(wrapped_function):
@wraps(wrapped_function)
def new_function(*args, **kwargs):
def task_call(flask_app, environ):
# Create a request context similar to that of the original request
# so that the task can have access to flask.g, flask.request, etc.
with flask_app.request_context(environ):
try:
tasks[task_id]['return_value'] = wrapped_function(*args, **kwargs)
except HTTPException as e:
tasks[task_id]['return_value'] = current_app.handle_http_exception(e)

# Record the task, and then launch it
tasks[task_id] = {'task_thread': threading.Thread(

The requests package has a very nice API for HTTP requests, adding a custom header works like this (source: official docs):
>>> import requests
>>> response = requests.get(
... 'https://website.com/id', headers={'Authorization': 'access_token myToken'})
If you don't want to use an external dependency, the same thing using urllib2 of the standard library looks like this (source: the missing manual):
>>> import urllib2
>>> response = urllib2.urlopen(
... urllib2.Request('https://website.com/id', headers={'Authorization': 'access_token myToken'})
It is terrible, but you can try to use
select
SUBSTRING(Table1.Col1,0,PATINDEX('%|%=',Table1.Col1)) as myString
from
Table1
This code is probably not 100% right though. need to be adjusted
If this occurs trying to delete a folder (on *nix) and Refresh does not help, open a terminal and look for a symlink below the folder you are trying to delete and remove this manually. This solved my issues.
Another option like Gavin Palmer answer is to use the .pem
file but with a curl option
download the last updated .pem
file from https://curl.haxx.se/docs/caextract.html and save it somewhere on your server(outside the public folder)
set the option in your code instead of the php.ini
file.
In your code
curl_setopt($ch, CURLOPT_CAINFO, $_SERVER['DOCUMENT_ROOT'] . "/../cacert-2017-09-20.pem");
NOTE: setting the cainfo in the php.ini
like @Gavin Palmer did is better than setting it in your code like I did, because it will save a disk IO every time the function is called, I just make it like this in case you want to test the cainfo file on the fly instead of changing the php.ini
while testing your function.
If source code is on Github, you can use their comparing tool: https://help.github.com/articles/comparing-commits-across-time/
You can compose all the functions into one and call them.Libraries like Ramdajs has a function to compose multiple functions into one.
<a href="#" onclick="R.compose(fn1,fn2,fn3)()">Click me To fire some functions</a>
or you can put the composition as a seperate function in js file and call it
const newFunction = R.compose(fn1,fn2,fn3);
<a href="#" onclick="newFunction()">Click me To fire some functions</a>
While drive allows you to edit plain text and HTML files I don't believe they allow the HTML to actually be displayed. I don't think they want people hosting websites from their drive space.
Simple way to compare time is :
$time = date('H:i:s',strtotime("11 PM"));
if($time < date('H:i:s')){
// your code
}
For instance your json looks like this : {"id":1,"content":"Hello, World!"}
You can access this thru angularjs like so:
angular.module('app', [])
.controller('myApp', function($scope, $http) {
$http.get('http://yourapp/api').
then(function(response) {
$scope.datafromapi = response.data;
});
});
Then on your html you would do it like this:
<!doctype html>
<html ng-app="myApp">
<head>
<title>Hello AngularJS</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.3/angular.min.js"></script>
<script src="hello.js"></script>
</head>
<body>
<div ng-controller="myApp">
<p>The ID is {{datafromapi.id}}</p>
<p>The content is {{datafromapi.content}}</p>
</div>
</body>
</html>
This calls the CDN for angularjs in case you don't want to download them.
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.3/angular.min.js"></script>
<script src="hello.js"></script>
Hope this helps.
Set python3 as a main version in the terminal: ln -sf python3 /usr/bin/python

Use the same code as jQuery does:
jQuery.expr.pseudos.visible = function( elem ) {
return !!( elem.offsetWidth || elem.offsetHeight || elem.getClientRects().length );
};
So, in a function:
function isVisible(e) {
return !!( e.offsetWidth || e.offsetHeight || e.getClientRects().length );
}
Works like a charm in my Win/IE10, Linux/Firefox.45, Linux/Chrome.52...
Many thanks to jQuery without jQuery!
I also had this problem. The error was in the htaccess. If you have a rewrite rule that affects the action url, you will not able to read the POST variable.
To fix this adding, you have to add this rule to htaccess, at the beginning, to avoid to rewrite the url:
RewriteRule ^my_action.php - [PT]
If you want to SELECT
based on the value of another SELECT
, then you probably want a "subselect":
http://beginner-sql-tutorial.com/sql-subquery.htm
For example, (from the link above):
You want the first and last names from table "student_details" ...
But you only want this information for those students in "science" class:
SELECT id, first_name
FROM student_details
WHERE first_name IN (SELECT first_name
FROM student_details
WHERE subject= 'Science');
Frankly, I'm not sure this is what you're looking for or not ... but I hope it helps ... at least a little...
IMHO...
How about checking this before doing the redirect:
if (!Response.IsRequestBeingRedirected)
{
//do the redirect
}
At some point I read a reasonably convincing argument on Perlmonks that testing the type of a scalar with ref
or reftype
is a bad idea. I don't recall who put the idea forward, or the link. Sorry.
The point was that in Perl there are many mechanisms that make it possible to make a given scalar act like just about anything you want. If you tie
a filehandle so that it acts like a hash, the testing with reftype
will tell you that you have a filehanle. It won't tell you that you need to use it like a hash.
So, the argument went, it is better to use duck typing to find out what a variable is.
Instead of:
sub foo {
my $var = shift;
my $type = reftype $var;
my $result;
if( $type eq 'HASH' ) {
$result = $var->{foo};
}
elsif( $type eq 'ARRAY' ) {
$result = $var->[3];
}
else {
$result = 'foo';
}
return $result;
}
You should do something like this:
sub foo {
my $var = shift;
my $type = reftype $var;
my $result;
eval {
$result = $var->{foo};
1; # guarantee a true result if code works.
}
or eval {
$result = $var->[3];
1;
}
or do {
$result = 'foo';
}
return $result;
}
For the most part I don't actually do this, but in some cases I have. I'm still making my mind up as to when this approach is appropriate. I thought I'd throw the concept out for further discussion. I'd love to see comments.
Update
I realized I should put forward my thoughts on this approach.
This method has the advantage of handling anything you throw at it.
It has the disadvantage of being cumbersome, and somewhat strange. Stumbling upon this in some code would make me issue a big fat 'WTF'.
I like the idea of testing whether a scalar acts like a hash-ref, rather that whether it is a hash ref.
I don't like this implementation.
If your proxy server or container adds the following header when serving the .js file, it will force some browsers such as Chrome to perform strict checking of MIME types:
X-Content-Type-Options: nosniff
Remove this header to prevent Chrome performing the MIME check.
After updating to ADT 22.0.1, due to Android private libraries, the Google Maps service was giving some error and the app crashed. So I found the solution finally and it worked for me.
Just install the Google Play service library and then go to google-play-service/libproject/google-play-services_lib
from https://www.dropbox.com/sh/2ok76ep7lmav0qf/9XVlv61D2b
. Import that into your workspace. Clean your project where you want to use gogole-play-services-lib and then build it again and go to the Project -> Properties -> Java BuildPath -> select "Android Private Libraries, Android Dependencies, google-play-service"
In Properties itself, go to Android and then choose any of the versions and then choose add and select google-play-service-lib and then press apply and finally OK.
At last, go to the Project -> Android Tools -> Android Support Libraries. Accept the license and after installing then run your project.
It will work fine.
In Addition to @thefourtheye answer, using predicate instead of traditional anonymous functions:
_.remove(obj.subTopics, (currentObject) => {
return currentObject.subTopicId === stToDelete;
});
OR
obj.subTopics = _.filter(obj.subTopics, (currentObject) => {
return currentObject.subTopicId !== stToDelete;
});
if you want to change only the colour of the flag on hover
use this:
.fa-flag:hover {_x000D_
color: red;_x000D_
}
_x000D_
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>_x000D_
_x000D_
<i class="fa fa-flag fa-3x"></i>
_x000D_
Just use in OOP manner a class like this:
class div
{
public int remainder;
public int quotient(int dividend, int divisor)
{
remainder = ...;
return ...;
}
}
The function member returns the quotient which most callers are primarily interested in. Additionally it stores the remainder as a data member, which is easily accessible by the caller afterwards.
This way you can have many additional "return values", very useful if you implement database or networking calls, where lots of error messages may be needed but only in case an error occurs.
I entered this solution also in the C++ question that OP is referring to.
This might work for you (GNU sed):
sed -si '/#include/{s//& "newfile.h\n&/;:a;$!{n;ba}}' file1 file2 file....
or if memory is not a problem:
sed -si ':a;$!{N;ba};s/#include/& "newfile.h\n&/' file1 file2 file...
In ggplot2 you can do smooths in a number of ways, for example:
library(ggplot2)
ggplot(mtcars, aes(wt, mpg)) + geom_point() +
geom_smooth(method = "gam", formula = y ~ poly(x, 2))
ggplot(mtcars, aes(wt, mpg)) + geom_point() +
geom_smooth(method = "loess", span = 0.3, se = FALSE)
This question is similar to How do I limit the number of rows returned by an Oracle query after ordering?.
It talks about how to implement a MySQL limit on an oracle database which judging by your tags and post is what you are using.
The relevant section is:
select *
from
( select *
from emp
order by sal desc )
where ROWNUM <= 5;
Step 1: check the return code: if($content === FALSE) { // handle error here... }
Step 2: suppress the warning by putting an error control operator (i.e. @
) in front of the call to file_get_contents():
$content = @file_get_contents($site);

Apologies, this is using Jambi (Qt for Java) so the syntax is different, but the theory is the same.
To answer this not from an aesthetical but performance-oriented point of view, I've put all of the above suggestions through a benchmark. To be precise, I've considered the suggestions
x[length(x)]
mylast(x)
, where mylast
is a C++ function implemented through Rcpp,tail(x, n=1)
dplyr::last(x)
x[end(x)[1]]]
rev(x)[1]
and applied them to random vectors of various sizes (10^3, 10^4, 10^5, 10^6, and 10^7). Before we look at the numbers, I think it should be clear that anything that becomes noticeably slower with greater input size (i.e., anything that is not O(1)) is not an option. Here's the code that I used:
Rcpp::cppFunction('double mylast(NumericVector x) { int n = x.size(); return x[n-1]; }')
options(width=100)
for (n in c(1e3,1e4,1e5,1e6,1e7)) {
x <- runif(n);
print(microbenchmark::microbenchmark(x[length(x)],
mylast(x),
tail(x, n=1),
dplyr::last(x),
x[end(x)[1]],
rev(x)[1]))}
It gives me

This immediately rules out anything involving rev
or end
since they're clearly not O(1)
(and the resulting expressions are evaluated in a non-lazy fashion). tail
and dplyr::last
are not far from being O(1)
but they're also considerably slower than mylast(x)
and x[length(x)]
. Since mylast(x)
is slower than x[length(x)]
and provides no benefits (rather, it's custom and does not handle an empty vector gracefully), I think the answer is clear: Please use x[length(x)]
.
General steps:
Object initializer
If your constructor with the parameter isn't doing anything besides setting a property, you can do this in C# 3 or better using an object initializer rather than calling a constructor (which is impossible, as has been mentioned):
public static string GetAllItems<T>(...) where T : new()
{
...
List<T> tabListItems = new List<T>();
foreach (ListItem listItem in listCollection)
{
tabListItems.Add(new T() { YourPropertyName = listItem } ); // Now using object initializer
}
...
}
Using this, you can always put any constructor logic in the default (empty) constructor, too.
Activator.CreateInstance()
Alternatively, you could call Activator.CreateInstance() like so:
public static string GetAllItems<T>(...) where T : new()
{
...
List<T> tabListItems = new List<T>();
foreach (ListItem listItem in listCollection)
{
object[] args = new object[] { listItem };
tabListItems.Add((T)Activator.CreateInstance(typeof(T), args)); // Now using Activator.CreateInstance
}
...
}
Note that Activator.CreateInstance can have some performance overhead that you may want to avoid if execution speed is a top priority and another option is maintainable to you.

I created a DefaultableDictionary to do exactly what you are asking for!
using System;
using System.Collections;
using System.Collections.Generic;
using System.Collections.ObjectModel;
namespace DefaultableDictionary {
public class DefaultableDictionary<TKey, TValue> : IDictionary<TKey, TValue> {
private readonly IDictionary<TKey, TValue> dictionary;
private readonly TValue defaultValue;
public DefaultableDictionary(IDictionary<TKey, TValue> dictionary, TValue defaultValue) {
this.dictionary = dictionary;
this.defaultValue = defaultValue;
}
public IEnumerator<KeyValuePair<TKey, TValue>> GetEnumerator() {
return dictionary.GetEnumerator();
}
IEnumerator IEnumerable.GetEnumerator() {
return GetEnumerator();
}
public void Add(KeyValuePair<TKey, TValue> item) {
dictionary.Add(item);
}
public void Clear() {
dictionary.Clear();
}
public bool Contains(KeyValuePair<TKey, TValue> item) {
return dictionary.Contains(item);
}
public void CopyTo(KeyValuePair<TKey, TValue>[] array, int arrayIndex) {
dictionary.CopyTo(array, arrayIndex);
}
public bool Remove(KeyValuePair<TKey, TValue> item) {
return dictionary.Remove(item);
}
public int Count {
get { return dictionary.Count; }
}
public bool IsReadOnly {
get { return dictionary.IsReadOnly; }
}
public bool ContainsKey(TKey key) {
return dictionary.ContainsKey(key);
}
public void Add(TKey key, TValue value) {
dictionary.Add(key, value);
}
public bool Remove(TKey key) {
return dictionary.Remove(key);
}
public bool TryGetValue(TKey key, out TValue value) {
if (!dictionary.TryGetValue(key, out value)) {
value = defaultValue;
}
return true;
}
public TValue this[TKey key] {
get
{
try
{
return dictionary[key];
} catch (KeyNotFoundException) {
return defaultValue;
}
}
set { dictionary[key] = value; }
}
public ICollection<TKey> Keys {
get { return dictionary.Keys; }
}
public ICollection<TValue> Values {
get
{
var values = new List<TValue>(dictionary.Values) {
defaultValue
};
return values;
}
}
}
public static class DefaultableDictionaryExtensions {
public static IDictionary<TKey, TValue> WithDefaultValue<TValue, TKey>(this IDictionary<TKey, TValue> dictionary, TValue defaultValue ) {
return new DefaultableDictionary<TKey, TValue>(dictionary, defaultValue);
}
}
}
This project is a simple decorator for an IDictionary object and an extension method to make it easy to use.
The DefaultableDictionary will allow for creating a wrapper around a dictionary that provides a default value when trying to access a key that does not exist or enumerating through all the values in an IDictionary.
Example: var dictionary = new Dictionary<string, int>().WithDefaultValue(5);
Blog post on the usage as well.
As mentioned here: Re: BUG #4243: Idle in transaction it is probably best to check your pg_locks table to see what is being locked and that might give you a better clue where the problem lies.
