If you also want to give a suggested name to the file (instead of the default 'download') you can use the following in Chrome, Firefox and some IE versions:
function downloadURI(uri, name) {
var link = document.createElement("a");
link.download = name;
link.href = uri;
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
delete link;
}
And the following example shows it's use:
downloadURI("data:text/html,HelloWorld!", "helloWorld.txt");
With the code you provided, you cannot expect anything to happen. I second @mashappslabs : first add an event handler :
$("selector").click(function() {
console.log("element was clicked"); // or alert("click");
});
then trigger your event :
$("selector").click(); //or
$("selector").trigger("click");
and you should see the message in your console.
The simplest way to initialize an array
Create array
$array = @()
Create your header
$line = "" | select name,age,phone
Fill the line
$line.name = "Leandro"
$line.age = "39"
$line.phone = "555-555555"
Add line to $array
$array += $line
Result
$array
name age phone
---- --- -----
Leandro 39 555-555555
NOTE: I apologize in advance for answering only a portion of the above question. However, I found these commands to be useful for my current unix needs.
Uploading specific files from a local machine to a remote machine:
~/Desktop/dump_files$ scp file1.txt file2.txt lab1.cpp etc.ext [email protected]:Folder1/DestinationFolderForFiles/
Uploading an entire directory from a local machine to a remote machine:
~$ scp -r Desktop/dump_files [email protected]:Folder1/DestinationFolderForFiles/
Downloading an entire directory from a remote machine to a local machine:
~/Desktop$ scp -r [email protected]:Public/web/ Desktop/
Suppose I have a model User
User.find(id)
Returns a row where primary key = id. The return type will be User
object.
User.find_by(email:"[email protected]")
Returns first row with matching attribute or email in this case. Return type will be User
object again.
Note :- User.find_by(email: "[email protected]")
is similar to User.find_by_email("[email protected]")
User.where(project_id:1)
Returns all users in users table where attribute matches.
Here return type will be ActiveRecord::Relation
object. ActiveRecord::Relation
class includes Ruby's Enumerable
module so you can use it's object like an array and traverse on it.
I looked at these, I was getting it sorted, and then it broke the binding, as above. Came up with this solution, though simpler than most of yours, it appears to do what I want to,,,
public static ObservableCollection<string> OrderThoseGroups( ObservableCollection<string> orderThoseGroups)
{
ObservableCollection<string> temp;
temp = new ObservableCollection<string>(orderThoseGroups.OrderBy(p => p));
orderThoseGroups.Clear();
foreach (string j in temp) orderThoseGroups.Add(j);
return orderThoseGroups;
}
g++ file_name.cpp -o executable_file_name
(i) -o option is used to show error in the code (ii) if there is no error in the code_file, then it will generate an executable file.
./executable_file_name
Kotlin Style way to do this more simple (example):
isVisible = false
Complete example:
if (some_data_array.details == null){
holder.view.some_data_array.isVisible = false}
EDIT: Updated with the latest Location Service API from Google Play Services library (July 2014)
I would recommend you to use the new Location Service API, available from the Google Play Services library, which provides a more powerful, high-level framework that automates tasks such as location provider choice and power management. According to the official documentation: "... Location API make it easy for you to build location-aware applications, without needing to focus on the details of the underlying location technology. They also let you minimize power consumption by using all of the capabilities of the device hardware."
For further information visit: Making Your App Location-Aware
To see a full example using the latest Location Service API visit: Android LocationClient class is deprecated but used in documentation
I bet the problem is being shown in this line
SqlDataReader dr3 = com2.ExecuteReader();
I suggest that you execute the first reader and do a dr.Close();
and the iterate historicos
, with another loop, performing the com2.ExecuteReader()
.
public List<string[]> get_dados_historico_verificacao_email_WEB(string email)
{
List<string[]> historicos = new List<string[]>();
conecta();
sql = "SELECT * FROM historico_verificacao_email WHERE nm_email = '" + email + "' ORDER BY dt_verificacao_email DESC, hr_verificacao_email DESC";
com = new SqlCommand(sql, conexao);
SqlDataReader dr = com.ExecuteReader();
if (dr.HasRows)
{
while (dr.Read())
{
string[] dados_historico = new string[6];
dados_historico[0] = dr["nm_email"].ToString();
dados_historico[1] = dr["dt_verificacao_email"].ToString();
dados_historico[1] = dados_historico[1].Substring(0, 10);
//System.Windows.Forms.MessageBox.Show(dados_historico[1]);
dados_historico[2] = dr["hr_verificacao_email"].ToString();
dados_historico[3] = dr["ds_tipo_verificacao"].ToString();
dados_historico[5] = dr["cd_login_usuario"].ToString();
historicos.Add(dados_historico);
}
dr.Close();
sql = "SELECT COUNT(e.cd_historico_verificacao_email) QT FROM emails_lidos e WHERE e.cd_historico_verificacao_email = '" + dr["cd_historico_verificacao_email"].ToString() + "'";
tipo_sql = "seleção";
com2 = new SqlCommand(sql, conexao);
for(int i = 0 ; i < historicos.Count() ; i++)
{
SqlDataReader dr3 = com2.ExecuteReader();
while (dr3.Read())
{
historicos[i][4] = dr3["QT"].ToString(); //quantidade de emails lidos naquela verificação
}
dr3.Close();
}
}
return historicos;
Just use parenthesis for SELECT clause into INSERT. For example like this :
INSERT INTO Table1 (col1, col2, your_desired_value_from_select_clause, col3)
VALUES (
'col1_value',
'col2_value',
(SELECT col_Table2 FROM Table2 WHERE IdTable2 = 'your_satisfied_value_for_col_Table2_selected'),
'col3_value'
);
I do it this way for Android 2.2 Froyo release: basically use eclipse to create a class like: public class SomePickContactName extends Activity
then insert this code. Remember to add the private class variables and CONSTANTS referenced in my version of the code:
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intentContact, PICK_CONTACT);
}//onCreate
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
if (requestCode == PICK_CONTACT)
{
getContactInfo(intent);
// Your class variables now have the data, so do something with it.
}
}//onActivityResult
protected void getContactInfo(Intent intent)
{
Cursor cursor = managedQuery(intent.getData(), null, null, null, null);
while (cursor.moveToNext())
{
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if ( hasPhone.equalsIgnoreCase("1"))
hasPhone = "true";
else
hasPhone = "false" ;
if (Boolean.parseBoolean(hasPhone))
{
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
while (phones.moveToNext())
{
phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
}
// Find Email Addresses
Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,null, null);
while (emails.moveToNext())
{
emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
}
emails.close();
Cursor address = getContentResolver().query(
ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.StructuredPostal.CONTACT_ID + " = " + contactId,
null, null);
while (address.moveToNext())
{
// These are all private class variables, don't forget to create them.
poBox = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POBOX));
street = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET));
city = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY));

I had the same error when I deployed my app. I've got solution from this site: Component with CLSID XXX failed due to the following error: 80070005 Access is denied
Here is this solution:
In DCOMCNFG, right click on the My Computer and select properties.
Choose the COM Securities tab.
In Access Permissions, click Edit Defaults and add Network Service to it and give it Allow local access permission. Do the same for < Machine_name >\Users.
In Launch and Activation Permissions, click Edit Defaults and add Network Service to it and give it Local launch and Local Activation permission. Do the same for < Machine_name >\Users.

In my benchmark script, each method is tested 10000 times and the difference of the total time for each method is printed. You should this on your own configuration, I'm sure results will vary!
These are my results:
SELECT NULL" -> PGO()
faster by ~ 0.35 secondsSHOW TABLE STATUS" -> mysqli()
faster by ~ 2.3 secondsSELECT * FROM users" -> mysqli()
faster by ~ 33 secondsNote: by using ->fetch_row() for mysqli, the column names are not added to the array, I didn't find a way to do that in PGO. But even if I use ->fetch_array() , mysqli is slightly slower but still faster than PGO (except for SELECT NULL).
PowerShell 3 has the $PSScriptRoot
automatic variable:
Contains the directory from which a script is being run.
In Windows PowerShell 2.0, this variable is valid only in script modules (.psm1). Beginning in Windows PowerShell 3.0, it is valid in all scripts.
Don't be fooled by the poor wording. PSScriptRoot
is the directory of the current file.
In PowerShell 2, you can calculate the value of $PSScriptRoot
yourself:
# PowerShell v2
$PSScriptRoot = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition
In my case, the issue was due to WAMP using a different php.ini for CLI than Apache, so your settings made through the WAMP menu don't apply to CLI. Just modify the CLI php.ini and it works.
Using the width function:
$('div#somediv').width('70%');
will turn:
<div id="somediv" />
into:

Python 3, read all of the file at once:
with open("filename", "rb") as binary_file:
# Read the whole file at once
data = binary_file.read()
print(data)
You can iterate whatever you want using data
variable.
There are two strategies:
Use Database-generated ID
(int
or GUID
)
Cons:
You should perform SaveChanges()
to get the ID
for just saved entities.
Pros:
Can use int
identity.
Use client generated ID
- GUID only.
Pros:
Minification of SaveChanges
operations.
Able to insert a big graph of new objects per one operation.
Cons:
Allowed only for GUID

As user2357112 mentioned in the comments, you cannot use chained comparisons here. For elementwise comparison you need to use &
. That also requires using parentheses so that &
wouldn't take precedence.
It would go something like this:
mask = ((50 < df['heart rate']) & (101 > df['heart rate']) & (140 < df['systolic...
In order to avoid that, you can build series for lower and upper limits:
low_limit = pd.Series([90, 50, 95, 11, 140, 35], index=df.columns)
high_limit = pd.Series([160, 101, 100, 19, 160, 39], index=df.columns)
Now you can slice it as follows:
mask = ((df < high_limit) & (df > low_limit)).all(axis=1)
df[mask]
Out:

161 153 36
286 156 37
435 155 36
499 149 36
And for assignment you can use np.where:
df['class'] = np.where(mask, 'excellent', 'critical')
All of the previous answers explain what the OP 'should' do. I am explaining what the .SelectedText
property is.
The .SelectedText
property is not the text in the combobox
. It is the text that is highlighted. It is the same as .SelectedText
property for a textbox
.
The following picture shows that the .SelectedText
property would be equal to "ort".
Found this answer here and wanted to reference it as it appear much cleaner than the accepted answer:
function blobToDataURL(blob, callback) {
var fileReader = new FileReader();
fileReader.onload = function(e) {callback(e.target.result);}
fileReader.readAsDataURL(blob);
}
If you need exact your example, you should add format to ToString()
string test = DateTime.ParseExact(DateTime.Now.ToString("dd.MM.yyyy"), "dd.MM.yyyy", CultureInfo.InvariantCulture).ToString("yyyy-MM-dd");
But it's better to use straight formatting:
string test = DateTime.Now.ToString("yyyy-MM-dd")
Another possibility is to use a pseudo selector :after or :before
tr.highlight td:last-child:after
{
content: "\0a0";
line-height: 3em;
}
That might avoid issues with browser that don't understand the pseudo selectors, plus background-colors are not an issue.
The downside is however, that it adds some extra whitespace after the last cell.
I ran into this issue as well. I don't know the technical details of what was actually happening. However, in my situation, the root cause was that there was cascading deletes setup in the Oracle database and my JPA/Hibernate code was also trying to do the cascading delete calls. So my advice is to make sure that you know exactly what is happening.
The S parameter does not do anything on its own.
/S Modifies the treatment of string after /C or /K (see below)
/C Carries out the command specified by string and then terminates
/K Carries out the command specified by string but remains
Try something like this instead
Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)
You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.
Shell("perl a.pl c:\temp")
-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here
Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1
wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn
try this, work for me

Here are a couple of things missing in the previous answers:
Set header in your PHP:
header('Content-type: application/json');
echo json_encode($array);
json_encode()
can return a JavaScript array instead of JavaScript object, see:
Returning JSON from a PHP Script
This could be important to know in some cases as arrays and objects are not the same.
Most of these answers are wrong or are only telling half the story.
For example:
const AWESOME = 'Bob'; // Valid
Bad example:
const AWESOME = whatIsMyName(); // Invalid (Function call)
const WEAKNESS = 4+5+6; // Invalid (Arithmetic)
const FOO = BAR . OF . SOAP; // Invalid (Concatenation)
To create variable constants use define() like so:
define('AWESOME', whatIsMyName()); // Valid
define('WEAKNESS', 4 + 5 + 6); // Valid
define('FOO', BAR . OF . SOAP); // Valid
Shef's answer doesn't compile for me. It looks like he's using RegEx in String.contains()
. If you want to use RegEx use this:
String strWithNumber = "This string has a 1 number";
String strWithoutNumber = "This string has a number";
System.out.println(strWithNumber.matches(".*\\d.*"));
System.out.println(strWithoutNumber.matches(".*\\d.*"));
Yes, but not for free.

On Microsoft Windows, gvim wouldn't allow you to select non-monospaced fonts. Unfortunately Latha is a non-monospaced font.
There is a hack way to make it happen: Using FontForge (you can download Windows binary from http://www.geocities.jp/meir000/fontforge/) to edit the Latha.ttf and mark it as a monospaced font. Doing like this:
Good luck!
NumPy is slower because it casts the input to boolean values (so None and 0 becomes False and everything else becomes True).
import pandas as pd
import numpy as np
s = pd.Series([True, None, False, True])
np.logical_not(s)
gives you
0 False
1 True
2 True
3 False
dtype: object
whereas ~s would crash. In most cases tilde would be a safer choice than NumPy.
Pandas 0.25, NumPy 1.17
a <- 1:120
b <- a[seq(1, length(a), 6)]
To set up an external DB and still use your local DB, you need to edit the config.inc.php file:
On Ubuntu: sudo gedit /etc/phpmyadmin/config.inc.php
The file is roughly set up like this:
if (!empty($dbname)) {
//Your local db setup
$i++;
}
What you need to do is duplicate the "your local db setup" by copying and pasting it outside of the IF
statement I've shown in the code below, and change the host to you external IP. Mine for example is:
$cfg['Servers'][$i]['host'] = '10.10.1.90:23306';
You can leave the defaults (unless you know you need to change them)
Save and refresh your PHPMYADMIN login page and a new dropdown should appear. You should be good to go.
EDIT: if you want to give the server a name to select at login page, rather than having just the IP address to select, add this to the server setup:
$cfg['Servers'][$i]['verbose'] = 'Name to show when selecting your server';
It's good if you have multiple server configs.
On a slightly different note, I had to make a virtual device without GSM Modem Support so that the internet on my emulator would work.
You can create $i
outside the loop and do $i++
at the bottom of the loop.
Example:
Let's say table A has two children B and C. Then we can use the following syntax to drop all tables.
DROP TABLE IF EXISTS B,C,A;
This can be placed in the beginning of the script instead of individually dropping each table.
You should use options.addAll(allPoints);
instead of options.add(point);
Here's an example
// in the service
getVehicles(){
return Observable.interval(2200).map(i=> [{name: 'car 1'},{name: 'car 2'}])
}
// in the controller
vehicles: Observable<Array<any>>
ngOnInit() {
this.vehicles = this._vehicleService.getVehicles();
}
// in template
<div *ngFor='let vehicle of vehicles | async'>
{{vehicle.name}}
</div>

The accepted answer is the correct command, I just want to add one additional thing, when extracting the key if you leave the PEM password("Enter PEM pass phrase:"
) blank then the complete key will not be extracted but only the localKeyID
will be extracted. To get the complete key you must specify a PEM password whem running the following command.
Please note that when it comes to Import password, you can specify the actual password for "Enter Import Password:"
or can leave this password blank:
openssl pkcs12 -in yourP12File.pfx -nocerts -out privateKey.pem
There are many ways to move repositories around, git bundle
is a nice way if you have insufficient network availability. Since a Git repository is really just a directory full of files, you can "clone" a repository by making a copy of the .git
directory in whatever way suits you best.
The most efficient way is to use an external repository somewhere (use GitHub or set up Gitosis), and then git push
.
There's the rlist package (http://cran.r-project.org/web/packages/rlist/index.html) to deal with various kinds of list operations.
Example (http://cran.r-project.org/web/packages/rlist/vignettes/Filtering.html):
library(rlist)
devs <-
list(
p1=list(name="Ken",age=24,
interest=c("reading","music","movies"),
lang=list(r=2,csharp=4,python=3)),
p2=list(name="James",age=25,
interest=c("sports","music"),
lang=list(r=3,java=2,cpp=5)),
p3=list(name="Penny",age=24,
interest=c("movies","reading"),
lang=list(r=1,cpp=4,python=2)))
list.remove(devs, c("p1","p2"))
Results in:
# $p3
# $p3$name
# [1] "Penny"
#
# $p3$age
# [1] 24
#
# $p3$interest
# [1] "movies" "reading"
#
# $p3$lang
# $p3$lang$r
# [1] 1
#
# $p3$lang$cpp
# [1] 4
#
# $p3$lang$python

You can also initialise it like this:
struct name sara = { "Sara", "Black" };
Since (as a special case) you're allowed to initialise char arrays from string constants.
Now, as for what a struct actually is - it's a compound type composed of other values. What sara
actually looks like in memory is a block of 20 consecutive char values (which can be referred to using sara.first
, followed by 0 or more padding bytes, followed by another block of 20 consecutive char values (which can be referred to using sara.last
). All other instances of the struct name
type are laid out in the same way.
In this case, it is very unlikely that there is any padding, so a struct name
is just a block of 40 characters, for which you have a name for the first 20 and the last 20.
You can find out how big a block of memory a struct name
takes using sizeof(struct name)
, and you can find out where within that block of memory each member of the structure is placed at using offsetof(struct name, first)
and offsetof(struct name, last)
.

first_date = INPUT(compress(char_date),date9.); format first_date date9.;
run;
I personally have tried it on SAS
You can use these solutions :
CSS rules applies to all tags that have following two classes :
.left.ui-class-selector {
/*style here*/
}
CSS rules applies to all tags that have <li>
with following two classes :
li.left.ui-class-selector {
/*style here*/
}
jQuery solution :
$("li.left.ui-class-selector").css("color", "red");
Javascript solution :
document.querySelector("li.left.ui-class-selector").style.color = "red";
Hate to be the one to bump an old subject, but I found this post extremely useful. After running performance tests on the snippets by stej and it's refinement by Graham Gold, plus the BITS suggestion by Nacht, I have decuded that:
Faced with the decision between the two... I found that Start-BitsTransfer supported Asynchronous mode. So here is the result of my merging the two.
function Copy-File {
# ref: https://stackoverflow.com/a/55527732/3626361
param([string]$From, [string]$To)
try {
$job = Start-BitsTransfer -Source $From -Destination $To `
-Description "Moving: $From => $To" `
-DisplayName "Backup" -Asynchronous
# Start stopwatch
$sw = [System.Diagnostics.Stopwatch]::StartNew()
Write-Progress -Activity "Connecting..."
while ($job.JobState.ToString() -ne "Transferred") {
switch ($job.JobState.ToString()) {
"Connecting" {
break
}
"Transferring" {
$pctcomp = ($job.BytesTransferred / $job.BytesTotal) * 100
$elapsed = ($sw.elapsedmilliseconds.ToString()) / 1000
if ($elapsed -eq 0) {
$xferrate = 0.0
}
else {
$xferrate = (($job.BytesTransferred / $elapsed) / 1mb);
}
if ($job.BytesTransferred % 1mb -eq 0) {
if ($pctcomp -gt 0) {
$secsleft = ((($elapsed / $pctcomp) * 100) - $elapsed)
}
else {
$secsleft = 0
}
Write-Progress -Activity ("Copying file '" + ($From.Split("\") | Select-Object -last 1) + "' @ " + "{0:n2}" -f $xferrate + "MB/s") `
-PercentComplete $pctcomp `
-SecondsRemaining $secsleft
}
break
}
"Transferred" {
break
}
Default {
throw $job.JobState.ToString() + " unexpected BITS state."
}
}
}
$sw.Stop()
$sw.Reset()
}
finally {
Complete-BitsTransfer -BitsJob $job
Write-Progress -Activity "Completed" -Completed
}
}
The difference is in how you create and append elements in the DOM.
If you create an element via document.createElement
, add an event listener, and append it to the DOM. Your events will fire.
If you create an element as a string like this: html += "<li>test</li>"`, the elment is technically just a string. Strings cannot have event listeners.
One solution is to create each element with document.createElement
and then add those to a DOM element directly.
// Sample
let li = document.createElement('li')
document.querySelector('ul').appendChild(li)
To pass get variables as well use $args
:
location / {
try_files $uri $uri/ /index.php?$args;
}
use fastcopy, a free tool. it has a delete option that is a lot faster then the way windows deletes files.
I've been pulling my hair out over this one for a couple of hours also. fakeartist appears correct though - I changed the file extension from .htm to .php and I can now see my page in Facebook! It also works if you change the extension to .aspx - perhaps it just needs to be a server side extension (I've not tried with .jsp).
a = ["foo","bar","baz",'bar','any','much']
indexes = [index for index in range(len(a)) if a[index] == 'bar']
In above code variable "ver" is assign to null, print "ver" before returning and see the value. As this "ver" having null service is send status as "204 No Content".
And about status code "405 - Method Not Allowed" will get this status code when rest controller or service only supporting GET method but from client side your trying with POST with valid uri request, during such scenario get status as "405 - Method Not Allowed"
To avoid problems of side effects after changing env
, especially using multiple nodes, it is better to set a temporary context.
One safe way to alter the environment is:
withEnv(['MYTOOL_HOME=/usr/local/mytool']) {
sh '$MYTOOL_HOME/bin/start'
}
This approach does not poison the env after the command execution.
Yes, however you will need to set your Binding flags to search for private fields (if your looking for the member outside of the class instance).
The binding flag you will need is: System.Reflection.BindingFlags.NonPublic
As of Swift 2.0, you can add a protocol extension. In my opinion, this is a better approach because the return type is Self
rather than UIView
, so the caller doesn't need to cast to the view class.
import UIKit
protocol UIViewLoading {}
extension UIView : UIViewLoading {}
extension UIViewLoading where Self : UIView {
// note that this method returns an instance of type `Self`, rather than UIView
static func loadFromNib() -> Self {
let nibName = "\(self)".characters.split{$0 == "."}.map(String.init).last!
let nib = UINib(nibName: nibName, bundle: nil)
return nib.instantiateWithOwner(self, options: nil).first as! Self
}
}
sed 's/.*/&:80/' abcd.txt >abcde.txt
Can't comment the last answer but the fix is relatively easy. Just set the background color of your opaque canvas:
#canvas1 { background-color: black; } //opaque canvas
#canvas2 { ... } //transparent canvas
I'm not sure but it looks like that the background-color is inherited as transparent from the body.
just remove and reDownload wrapper gradle.
Mac Home/.gradle/wrapper/dists/
remove gradle version and sync gradle in project and run project.
You should be able to replace it with a preg that removes all newlines and carriage returns. The code is:
preg_replace( "/\r|\n/", "", $yourString );
Even though the \n
characters are not appearing, if you are getting carriage returns there is an invisible character there. The preg replace should grab and fix those.
Use build job plugin for that task in order to trigger other jobs from jenkins file. You can add variety of logic to your execution such as parallel ,node and agents options and steps for triggering external jobs. I gave some easy-to-read cookbook example for that.
1.example for triggering external job from jenkins file with conditional example:
if (env.BRANCH_NAME == 'master') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam1',value: 'valueOfParam1')
booleanParam(name: 'keyNameOfParam2',value:'valueOfParam2')
]
}
2.example triggering multiple jobs from jenkins file with conditionals example:
def jobs =[
'job1Title'{
if (env.BRANCH_NAME == 'master') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam1',value: 'valueNameOfParam1')
booleanParam(name: 'keyNameOfParam2',value:'valueNameOfParam2')
]
}
},
'job2Title'{
if (env.GIT_COMMIT == 'someCommitHashToPerformAdditionalTest') {
build job:'exactJobName' , parameters:[
string(name: 'keyNameOfParam3',value: 'valueOfParam3')
booleanParam(name: 'keyNameOfParam4',value:'valueNameOfParam4')
booleanParam(name: 'keyNameOfParam5',value:'valueNameOfParam5')
]
}
}
(1..4).each { |i|
a = 9 if i==3
puts a
}
#nil
#nil
#9
#nil
for i in 1..4
a = 9 if i==3
puts a
end
#nil
#nil
#9
#9
In 'for' loop, local variable is still lives after each loop. In 'each' loop, local variable refreshes after each loop.
If your directory structure is like this,
site
application
controller
folder_1
first_controller.php
second_controller.php
folder_2
first_controller.php
second_controller.php
And when you are going to redirect it in same controller in which you are working then just write the following code.
$this->load->helper('url');
if ($some_value === FALSE/TRUE) //You may give 0/1 as well,its up to your logic
{
redirect('same_controller/method', 'refresh');
}
And if you want to redirect to another control then use the following code.
$this->load->helper('url');
if ($some_value === FALSE/TRUE) //You may give 0/1 as well,its up to your logic
{
redirect('folder_name/any_controller_name/method', 'refresh');
}
You will probably get an UAC prompt when importing the reg file. If you accept that, you have more rights.
Since you are writing to the 'policies' key, you need to have elevated rights. This part of the registry protected, because it contains settings that are administered by your system administrator.
Alternatively, you may try to run regedit.exe
from the command prompt.
regedit.exe /S yourfile.reg
.. should silently import the reg file. See RegEdit Command Line Options Syntax for more command line options.
There are quite a few projects that have settled on the Generic Graphics Toolkit for this. The GMTL in there is nice - it's quite small, very functional, and been used widely enough to be very reliable. OpenSG, VRJuggler, and other projects have all switched to using this instead of their own hand-rolled vertor/matrix math.
I've found it quite nice - it does everything via templates, so it's very flexible, and very fast.
Edit:
After the comments discussion, and edits, I thought I'd throw out some more information about the benefits and downsides to specific implementations, and why you might choose one over the other, given your situation.
GMTL -
Benefits: Simple API, specifically designed for graphics engines. Includes many primitive types geared towards rendering (such as planes, AABB, quatenrions with multiple interpolation, etc) that aren't in any other packages. Very low memory overhead, quite fast, easy to use.
Downsides: API is very focused specifically on rendering and graphics. Doesn't include general purpose (NxM) matrices, matrix decomposition and solving, etc, since these are outside the realm of traditional graphics/geometry applications.
Eigen -
Benefits: Clean API, fairly easy to use. Includes a Geometry module with quaternions and geometric transforms. Low memory overhead. Full, highly performant solving of large NxN matrices and other general purpose mathematical routines.
Downsides: May be a bit larger scope than you are wanting (?). Fewer geometric/rendering specific routines when compared to GMTL (ie: Euler angle definitions, etc).
IMSL -
Benefits: Very complete numeric library. Very, very fast (supposedly the fastest solver). By far the largest, most complete mathematical API. Commercially supported, mature, and stable.
Downsides: Cost - not inexpensive. Very few geometric/rendering specific methods, so you'll need to roll your own on top of their linear algebra classes.
NT2 -
Benefits: Provides syntax that is more familiar if you're used to MATLAB. Provides full decomposition and solving for large matrices, etc.
Downsides: Mathematical, not rendering focused. Probably not as performant as Eigen.
LAPACK -
Benefits: Very stable, proven algorithms. Been around for a long time. Complete matrix solving, etc. Many options for obscure mathematics.
Downsides: Not as highly performant in some cases. Ported from Fortran, with odd API for usage.
Personally, for me, it comes down to a single question - how are you planning to use this. If you're focus is just on rendering and graphics, I like Generic Graphics Toolkit, since it performs well, and supports many useful rendering operations out of the box without having to implement your own. If you need general purpose matrix solving (ie: SVD or LU decomposition of large matrices), I'd go with Eigen, since it handles that, provides some geometric operations, and is very performant with large matrix solutions. You may need to write more of your own graphics/geometric operations (on top of their matrices/vectors), but that's not horrible.
You MUST add below part to enable NameVirtualHost

The reason that the performance of instanceof
and getClass() == ...
is different is that they are doing different things.
instanceof
tests whether the object reference on the left-hand side (LHS) is an instance of the type on the right-hand side (RHS) or some subtype.
getClass() == ...
tests whether the types are identical.
So the recommendation is to ignore the performance issue and use the alternative that gives you the answer that you need.
Is using the
instanceOf
operator bad practice ?
Not necessarily. Overuse of either instanceOf
or getClass()
may be "design smell". If you are not careful, you end up with a design where the addition of new subclasses results in a significant amount of code reworking. In most situations, the preferred approach is to use polymorphism.
However, there are cases where these are NOT "design smell". For example, in equals(Object)
you need to test the actual type of the argument, and return false
if it doesn't match. This is best done using getClass()
.
Terms like "best practice", "bad practice", "design smell", "antipattern" and so on should be used sparingly and treated with suspicion. They encourage black-or-white thinking. It is better to make your judgements in context, rather than based purely on dogma; e.g. something that someone said is "best practice". I recommend that everyone read No Best Practices if they haven't already done so.
What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut
or via an instance e.g. shape.lolwut
but be careful while setting it as it will set an instance level attribute not class attribute
class Shape(object):
lolwut = 1
shape = Shape()
print Shape.lolwut, # 1
print shape.lolwut, # 1
# setting shape.lolwut would not change class attribute lolwut
# but will create it in the instance
shape.lolwut = 2
print Shape.lolwut, # 1
print shape.lolwut, # 2
# to change class attribute access it via class
Shape.lolwut = 3
print Shape.lolwut, # 3
print shape.lolwut # 2
output:
1 1 1 2 3 2
Somebody may expect output to be 1 1 2 2 3 3
but it would be incorrect
Try the to_date function.
I would personally prefer using "\n". This just puts a line break in Linux or Android.
For example,
String str = "I am the first part of the info being emailed.\nI am the second part.\n\nI am the third part.";
Output
I am the first part of the info being emailed.
I am the second part.
I am the third part.
A more generalized way would be to use,
System.getProperty("line.separator")
For example,
String str = "I am the first part of the info being emailed." + System.getProperty("line.separator") + "I am the second part." + System.getProperty("line.separator") + System.getProperty("line.separator") + "I am the third part.";
brings the same output as above. Here, the static getProperty()
method of the System
class can be used to get the "line.seperator
" for the particular OS.
But this is not necessary at all, as the OS here is fixed, that is, Android. So, calling a method every time is a heavy and unnecessary operation.
Moreover, this also increases your code length and makes it look kind of messy. A "\n" is sweet and simple.
here is how I do it in Swift 3
let threshold: CGFloat = 76.0 // threshold from bottom of tableView
internal func scrollViewDidScroll(_ scrollView: UIScrollView) {
let contentOffset = scrollView.contentOffset.y
let maximumOffset = scrollView.contentSize.height - scrollView.frame.size.height;
if (!isLoadingMore) && (maximumOffset - contentOffset <= threshold) {
self.loadVideosList()
}
}
If you are on a Unix system, Ctrl + Z will suspend Vim and give you a shell.
Type fg
to go back. Note that Vim creates a swap file while editing, and suspending Vim wouldn't delete that file (you aren't exiting Vim after all). On dumb terminals, this method was pretty standard for edit-compile-edit cycles using vi. I just found out that for me, gVim minimizes on typing Z.
Try this;
function X (id,parameter1,parameter2,...) {
$.ajax({
url: '@Url.Action("Actionre", "controller")',+ id,
type: "Get",
data: { parameter1: parameter1, parameter2: parameter2,...}
}).done(function(result) {
your code...
});
}
So controller method would looks like :
public ActionResult ActionName(id,parameter1, parameter2,...)
{
Your Code .......
}

What I usually do is have a registry "Open Here" helper in order to open a cygwin shell with administrative privileges quite easy from anywhere in my computer.
Be aware you have to have the cygwin "chere" package installed, use "chere -i -m
" from an elevated cygwin shell first.
Assuming your cygwin installation is in C:\cygwin...
Here's the registry code:
Windows Registry Editor Version 5.00
[-HKEY_CLASSES_ROOT\Directory\shell\cygwin_bash]
[HKEY_CLASSES_ROOT\Directory\shell\cygwin_bash]
@="Open Cygwin Here as Root"
"HasLUAShield"=""

Hope this helps. Let me know if it works for you. Thanks.
PS: You can grab this code, copy and paste it and save it in a name.reg file to run it... or you can manually add the values.
To use the callback style (https://facebook.github.io/react/docs/refs-and-the-dom.html) as recommended on React's documentation you can add a definition for a property on the class:
export class Foo extends React.Component<{}, {}> {
// You don't need to use 'references' as the name
references: {
// If you are using other components be more specific than HTMLInputElement
myRef: HTMLInputElement;
} = {
myRef: null
}
...
myFunction() {
// Use like this
this.references.myRef.focus();
}
...
render() {
return(<input ref={(i: any) => { this.references.myRef = i; }}/>)
}
Try this:
function btnClick() {
var x = document.getElementById("mytable").getElementsByTagName("td");
x[0].innerHTML = "i want to change my cell color";
x[0].style.backgroundColor = "yellow";
}
Set from JS, backgroundColor
is the equivalent of background-color
in your style-sheet.
Note also that the .cells
collection belongs to a table row, not to the table itself. To get all the cells from all rows you can instead use getElementsByTagName()
.
Found this solution on another site. You can wrap the forEach in a try / catch scenario.
if(typeof StopIteration == "undefined") {
StopIteration = new Error("StopIteration");
}
try {
[1,2,3].forEach(function(el){
alert(el);
if(el === 1) throw StopIteration;
});
} catch(error) { if(error != StopIteration) throw error; }

row = $("body").find('#' + row_id);
More importantly doing the additional body.find has no impact on performance. The proper way to do this is simply:
row = $('#' + row_id);
Let us say your jsfunctions.js file has a function "display" and this file is stored in C:/Scripts/Jsfunctions.js
jsfunctions.js
var display = function(name) {
print("Hello, I am a Javascript display function",name);
return "display function return"
}
Now, in your java code, I would recommend you to use Java8 Nashorn. In your java class,
import java.io.FileNotFoundException;
import java.io.FileReader;
import javax.script.Invocable;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;
class Test {
public void runDisplay() {
ScriptEngine engine = new ScriptEngineManager().getEngineByName("nashorn");
try {
engine.eval(new FileReader("C:/Scripts/Jsfunctions.js"));
Invocable invocable = (Invocable) engine;
Object result;
result = invocable.invokeFunction("display", helloWorld);
System.out.println(result);
System.out.println(result.getClass());
} catch (FileNotFoundException | NoSuchMethodException | ScriptException e) {
e.printStackTrace();
}
}
}
Note: Get the absolute path of your javascript file and replace in FileReader() and run the java code. It should work.
Extention for prior Java 8 solution
String result = String.join(",", name);
If you need prefix or/ and suffix for array values
StringJoiner joiner = new StringJoiner(",");
for (CharSequence cs: name) {
joiner.add("'" + cs + "'");
}
return joiner.toString();
Or simple method concept
public static String genInValues(String delimiter, String prefix, String suffix, String[] name) {
StringJoiner joiner = new StringJoiner(delimiter);
for (CharSequence cs: name) {
joiner.add(prefix + cs + suffix);
}
return joiner.toString();
}
For example
For Oracle i need "id in (1,2,3,4,5)"
then use genInValues(",", "", "", name);
But for Postgres i need "id in (values (1),(2),(3),(4),(5))"
then use genInValues(",", "(", ")", name);
An excerpt from the RFC 2616: Hypertext Transfer Protocol -- HTTP/1.1:
The POST method is used to request that the origin server accept the entity enclosed in the request as a new subordinate of the resource identified by the Request-URI in the Request-Line. POST is designed to allow a uniform method to cover the following functions:
- Annotation of existing resources;
- Posting a message to a bulletin board, newsgroup, mailing list, or similar group of articles;
- Providing a block of data, such as the result of submitting a form, to a data-handling process;
- Extending a database through an append operation.
When you are connecting to another machine over SSH, you can enable X-Forwarding in SSH, so that X windows are forwarded encrypted through the SSH tunnel back to your machine. You can enable X forwarding by appending -X
to the ssh command line or setting ForwardX11 yes
in your SSH config file.
To check if the X-Forwarding was set up successfully (the server might not allow it), just try if echo $DISPLAY
outputs something like localhost:10.0
.
Use style="display: none;"
. Also, you probably don't need to have the DIV, just setting the style to display: none
on the checkbox would probably be sufficient.

If the parameter is passed by value (and is not a reference), usually there is not much difference whether the parameter is declared as const or not (unless it contains a reference member -- not a problem for built-in types). If the parameter is a reference or pointer, it is usually better to protect the referenced/pointed-to memory, not the pointer itself (I think you cannot make the reference itself const, not that it matters much as you cannot change the referee). It seems a good idea to protect everything you can as const. You can omit it without fear of making a mistake if the parameters are just PODs (including built-in types) and there is no chance of them changing further along the road (e.g. in your example the bool parameter).
I didn't know about the .h/.cpp file declaration difference, but it does make some sense. At the machine code level, nothing is "const", so if you declare a function (in the .h) as non-const, the code is the same as if you declare it as const (optimizations aside). However, it helps you to enlist the compiler that you will not change the value of the variable inside the implementation of the function (.ccp). It might come handy in the case when you're inheriting from an interface that allows change, but you don't need to change to parameter to achieve the required functionality.
//Create a date object using the current time
var now = new Date();
//Subtract one day from it
now.setDate(now.getDate()-1);
For me it turned out that I had a @JsonManagedReferece
in one entity without a @JsonBackReference
in the other referenced entity. This caused the marshaller to throw an error.
I removed the float from the second div to make it work.
Use readLines()
(with warn = FALSE
) to read the file into a character vector first.
After that use the text =
option to read the vector into a data frame with read.table()
pheasant <- read.table(
text = readLines(file.choose(), warn = FALSE),
header = TRUE,
sep = ","
)
Why don't you use the -Wno-deprecated
option to ignore deprecated warning messages?

You can use one commandline with two commands (gs
, convert
) connected through a pipe, if the first command can write its output to stdout, and if the second one can read its input from stdin.
... -o %stdout ...
). convert -background transparent - output.png
).Problem solved:
Complete solution:
gs -sDEVICE=pngalpha \
-o %stdout \
-r144 cover.pdf \
| \
convert \
-background transparent \
- \
cover.png
If you want to have a separate PNG per PDF page, you can use the %d
syntax:
gs -sDEVICE=pngalpha -o file-%03d.png -r144 cover.pdf
This will create PNG files named page-000.png
, page-001.png
, ... (Note that the %d
-counting is zero-based -- file-000.png
corresponds to page 1 of the PDF, 001
to page 2...
Or, if you want to keep your transparent background, for a 100-page PDF, do
for i in {1..100}; do \
\
gs -sDEVICE=pngalpha \
-dFirstPage="${i}" \
-dLastPage="${i}" \
-o %stdout \
-r144 input.pdf \

I had the same problem when I wrote two upstreams in NGINX conf
upstream php_upstream {
server unix:/var/run/php/my.site.sock;
server 127.0.0.1:9000;
}
...
fastcgi_pass php_upstream;
but in /etc/php/7.3/fpm/pool.d/www.conf
I listened the socket only
listen = /var/run/php/my.site.sock
So I need just socket, no any 127.0.0.1:9000
, and I just removed IP+port upstream
upstream php_upstream {
server unix:/var/run/php/my.site.sock;
}
This could be rewritten without an upstream
fastcgi_pass unix:/var/run/php/my.site.sock;
Use either COUNT(field)
or COUNT(*)
, and stick with it consistently, and if your database allows COUNT(tableHere)
or COUNT(tableHere.*)
, use that.
In short, don't use COUNT(1)
for anything. It's a one-trick pony, which rarely does what you want, and in those rare cases is equivalent to count(*)
count(*)
for countingUse *
for all your queries that need to count everything, even for joins, use *
SELECT boss.boss_id, COUNT(subordinate.*)
FROM boss
LEFT JOIN subordinate on subordinate.boss_id = boss.boss_id
GROUP BY boss.id
But don't use COUNT(*)
for LEFT joins, as that will return 1 even if the subordinate table doesn't match anything from parent table
SELECT boss.boss_id, COUNT(*)
FROM boss
LEFT JOIN subordinate on subordinate.boss_id = boss.boss_id
GROUP BY boss.id
Don't be fooled by those advising that when using *
in COUNT, it fetches entire row from your table, saying that *
is slow. The *
on SELECT COUNT(*)
and SELECT *
has no bearing to each other, they are entirely different thing, they just share a common token, i.e. *
.
In fact, if it is not permitted to name a field as same as its table name, RDBMS language designer could give COUNT(tableNameHere)
the same semantics as COUNT(*)
. Example:
For counting rows we could have this:
SELECT COUNT(emp) FROM emp
And they could make it simpler:
SELECT COUNT() FROM emp
And for LEFT JOINs, we could have this:
SELECT boss.boss_id, COUNT(subordinate)
FROM boss
LEFT JOIN subordinate on subordinate.boss_id = boss.boss_id
GROUP BY boss.id
But they cannot do that (COUNT(tableNameHere)
) since SQL standard permits naming a field with the same name as its table name:
CREATE TABLE fruit -- ORM-friendly name
(
fruit_id int NOT NULL,
fruit varchar(50), /* same name as table name,
and let's say, someone forgot to put NOT NULL */
shape varchar(50) NOT NULL,
color varchar(50) NOT NULL
)
And also, it is not a good practice to make a field nullable if its name matches the table name. Say you have values 'Banana', 'Apple', NULL, 'Pears' on fruit
field. This will not count all rows, it will only yield 3, not 4
SELECT count(fruit) FROM fruit
Though some RDBMS do that sort of principle (for counting the table's rows, it accepts table name as COUNT's parameter), this will work in Postgresql (if there is no subordinate
field in any of the two tables below, i.e. as long as there is no name conflict between field name and table name):
SELECT boss.boss_id, COUNT(subordinate)
FROM boss
LEFT JOIN subordinate on subordinate.boss_id = boss.boss_id
GROUP BY boss.id
But that could cause confusion later if we will add a subordinate
field in the table, as it will count the field(which could be nullable), not the table rows.
So to be on the safe side, use:
SELECT boss.boss_id, COUNT(subordinate.*)
FROM boss
LEFT JOIN subordinate on subordinate.boss_id = boss.boss_id
GROUP BY boss.id
count(1)
: The one-trick ponyIn particular to COUNT(1)
, it is a one-trick pony, it works well only on one table query:
SELECT COUNT(1) FROM tbl
But when you use joins, that trick won't work on multi-table queries without its semantics being confused, and in particular you cannot write:
-- count the subordinates that belongs to boss
SELECT boss.boss_id, COUNT(subordinate.1)
FROM boss
LEFT JOIN subordinate on subordinate.boss_id = boss.boss_id
GROUP BY boss.id
So what's the meaning of COUNT(1) here?
SELECT boss.boss_id, COUNT(1)
FROM boss
LEFT JOIN subordinate on subordinate.boss_id = boss.boss_id
GROUP BY boss.id
Is it this...?
-- counting all the subordinates only
SELECT boss.boss_id, COUNT(subordinate.boss_id)
FROM boss
LEFT JOIN subordinate on subordinate.boss_id = boss.boss_id
GROUP BY boss.id
Or this...?
-- or is that COUNT(1) will also count 1 for boss regardless if boss has a subordinate
SELECT boss.boss_id, COUNT(*)
FROM boss
LEFT JOIN subordinate on subordinate.boss_id = boss.boss_id
GROUP BY boss.id
By careful thought, you can infer that COUNT(1)
is the same as COUNT(*)
, regardless of type of join. But for LEFT JOINs result, we cannot mold COUNT(1)
to work as: COUNT(subordinate.boss_id)
, COUNT(subordinate.*)
So just use either of the following:
-- count the subordinates that belongs to boss
SELECT boss.boss_id, COUNT(subordinate.boss_id)
FROM boss
LEFT JOIN subordinate on subordinate.boss_id = boss.boss_id
GROUP BY boss.id
Works on Postgresql, it's clear that you want to count the cardinality of the set
-- count the subordinates that belongs to boss
SELECT boss.boss_id, COUNT(subordinate.*)
FROM boss
LEFT JOIN subordinate on subordinate.boss_id = boss.boss_id
GROUP BY boss.id
Another way to count the cardinality of the set, very English-like (just don't make a column with a name same as its table name) : http://www.sqlfiddle.com/#!1/98515/7
select boss.boss_name, count(subordinate)
from boss
left join subordinate on subordinate.boss_code = boss.boss_code
group by boss.boss_name
You cannot do this: http://www.sqlfiddle.com/#!1/98515/8
select boss.boss_name, count(subordinate.1)
from boss
left join subordinate on subordinate.boss_code = boss.boss_code
group by boss.boss_name
You can do this, but this produces wrong result: http://www.sqlfiddle.com/#!1/98515/9
select boss.boss_name, count(1)
from boss
left join subordinate on subordinate.boss_code = boss.boss_code
group by boss.boss_name
The overkill of having to capture and test every keystroke for the ENTER key really bugs me, so my solution relies on the following browser behavior:
Pressing ENTER will trigger a click event on the submit button (tested in IE11, Chrome 38, FF 31) ** (ref: http://mattsnider.com/how-forms-submit-when-pressing-enter/ )
So my solution is to remove the standard submit button (i.e. <input type="submit">
) so that the above behavior fails because there's no submit button to magically click when ENTER is pressed. Instead, I use a jQuery click handler on a regular button to submit the form via jQuery's .submit()
method.
<form id="myform" method="post">
<input name="fav_color" type="text">
<input name="fav_color_2" type="text">
<button type="button" id="form-button-submit">DO IT!</button>
</form>
<script>
$('#form-button-submit').click(function(){
$('#myform').submit();
});
</script>
Demo: http://codepen.io/anon/pen/fxeyv?editors=101
** this behavior is not applicable if the form has only 1 input field and that field is a 'text' input; in this case the form will be submitted upon ENTER key even if no submit button is present in the HTML markup (e.g. a search field). This has been standard browser behavior since the 90s.
I achieved 1600k concurrent idle socket connections, and at the same time 57k req/s on a Linux desktop (16G RAM, I7 2600 CPU). It's a single thread http server written in C with epoll. Source code is on github, a blog here.
Edit:
I did 600k concurrent HTTP connections (client & server) on both the same computer, with JAVA/Clojure . detail info post, HN discussion: http://news.ycombinator.com/item?id=5127251
The cost of a connection(with epoll):
Each registered file descriptor costs roughly 90 bytes on a 32-bit kernel, and roughly 160 bytes on a 64-bit kernel.
There exists now a dedicated bash script plugin called "Bash editor". It's available at eclipse market place:

What I do is pass the UIViewController pointer to the UIView (or an appropriate inheritance). I'm sorry I can't help with the IB approach to the problem because I don't believe in IB.
To answer the first commenter: sometimes you do need to know who called you because it determines what you can do. For example with a database you might have read access only or read/write ...
I had the same problema, but as described in the manual.pdf, you have to:
You are using an Oracle Instant Client but have not set all required environment variables:
- PATH: Needs to include the Instant Client directory where oci.dll is located
- TNS_ADMIN: Needs to point to the directory where tnsnames.ora is located.
- NLS_LANG: Defines the language, territory, and character set for the client.

The issue is that a notebooks is not a plain python file. The steps to import the .ipynb
file are outlined in the following: Importing notebook
I am pasting the code, so if you need it...you can just do a quick copy and paste. Notice that at the end I have the import primes
statement. You'll have to change that of course. The name of my file is primes.ipynb
. From this point on you can use the content inside that file as you would do regularly.

Now in Python >= 3.3 you can just call the timestamp() method to get the timestamp as a float.
import datetime
current_time = datetime.datetime.now(datetime.timezone.utc)
unix_timestamp = current_time.timestamp() # works if Python >= 3.3
unix_timestamp_plus_5_min = unix_timestamp + (5 * 60) # 5 min * 60 seconds
This actually can be done in pure bash:
hello=ho02123ware38384you443d34o3434ingtod38384day
re='(.*)[0-9]+(.*)'
while [[ $hello =~ $re ]]; do
hello=${BASH_REMATCH[1]}${BASH_REMATCH[2]}

If you're using jQuery with rails, be wary of allowing entry to methods without verifying the authenticity token.
jquery-ujs can manage the tokens for you
You should have it already as part of the jquery-rails gem, but you might need to include it in application.js with
//= require jquery_ujs
That's all you need - your ajax call should now work
For more information, see: https://github.com/rails/jquery-ujs

Use
git clone --depth=1 --branch=master git://someserver/somerepo dirformynewrepo
rm -rf ./dirformynewrepo/.git
dirformynewrepo
not a Git repository any more.If the above solution didn't work for you, you can use import { withRouter } from 'react-router-dom';
Using this you can export your child class as -
class MyApp extends Component{
// your code
}
export default withRouter(MyApp);
And your class with Router -
// your code
<Router>
...
<Route path="/myapp" component={MyApp} />
// or if you are sending additional fields
<Route path="/myapp" component={() =><MyApp process={...} />} />
<Router>
A simple example could be,
import tensorflow as tf
import numpy as np
a=tf.random_normal([2,3],0.0,1.0,dtype=tf.float32) #sampling from a std normal
print(type(a))
#<class 'tensorflow.python.framework.ops.Tensor'>
tf.InteractiveSession() # run an interactive session in Tf.
n now if we want this tensor a to be converted into a numpy array
a_np=a.eval()
print(type(a_np))
#<class 'numpy.ndarray'>
As simple as that!
Although the top answers are correct, I personally like to work with attached properties to enable the solution to be applied to any UIElement
, especially when the Window
is not aware of the element that should be focused. In my experience I often see a composition of several view models and user controls, where the window is often nothing more that the root container.
public sealed class AttachedProperties
{
// Define the key gesture type converter
[System.ComponentModel.TypeConverter(typeof(System.Windows.Input.KeyGestureConverter))]
public static KeyGesture GetFocusShortcut(DependencyObject dependencyObject)
{
return (KeyGesture)dependencyObject?.GetValue(FocusShortcutProperty);
}
public static void SetFocusShortcut(DependencyObject dependencyObject, KeyGesture value)
{
dependencyObject?.SetValue(FocusShortcutProperty, value);
}
/// <summary>
/// Enables window-wide focus shortcut for an <see cref="UIElement"/>.
/// </summary>
// Using a DependencyProperty as the backing store for FocusShortcut. This enables animation, styling, binding, etc...
public static readonly DependencyProperty FocusShortcutProperty =
DependencyProperty.RegisterAttached("FocusShortcut", typeof(KeyGesture), typeof(AttachedProperties), new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.None, new PropertyChangedCallback(OnFocusShortcutChanged)));
private static void OnFocusShortcutChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
if (!(d is UIElement element) || e.NewValue == e.OldValue)
return;
var window = FindParentWindow(d);
if (window == null)
return;
var gesture = GetFocusShortcut(d);
if (gesture == null)
{
// Remove previous added input binding.
for (int i = 0; i < window.InputBindings.Count; i++)
{
if (window.InputBindings[i].Gesture == e.OldValue && window.InputBindings[i].Command is FocusElementCommand)
window.InputBindings.RemoveAt(i--);
}
}
else
{
// Add new input binding with the dedicated FocusElementCommand.
// see: https://gist.github.com/shuebner20/349d044ed5236a7f2568cb17f3ed713d
var command = new FocusElementCommand(element);
window.InputBindings.Add(new InputBinding(command, gesture));
}
}
}
With this attached property you can define a focus shortcut for any UIElement. It will automatically register the input binding at the window containing the element.
<TextBox x:Name="SearchTextBox"
Text={Binding Path=SearchText}
local:AttachedProperties.FocusShortcutKey="Ctrl+Q"/>
The full sample including the FocusElementCommand implementation is available as gist: https://gist.github.com/shuebner20/c6a5191be23da549d5004ee56bcc352d
Disclaimer: You may use this code everywhere and free of charge. Please keep in mind, that this is a sample that is not suitable for heavy usage. For example, there is no garbage collection of removed elements because the Command will hold a strong reference to the element.
I made a builtin-only function to handle this with a focus on highest possible performance (for fun). It does not resolve symlinks, so it is basically the same as realpath -sm
.
## A bash-only mimic of `realpath -sm`.
## Give it path[s] as argument[s] and it will convert them to clean absolute paths
abspath () {
${*+false} && { >&2 echo $FUNCNAME: missing operand; return 1; };
local c s p IFS='/'; ## path chunk, absolute path, input path, IFS for splitting paths into chunks

return $r;
}
Note: This function does not handle paths starting with //
, as exactly two double slashes at the start of a path are implementation-defined behavior. However, it handles /
, ///
, and so on just fine.
This function seems to handle all edge cases properly, but there might still be some out there that I haven't dealt with.
Performance Note: when called with thousands of arguments, abspath
runs about 10x slower than realpath -sm
; when called with a single argument, abspath
runs >110x faster than realpath -sm
on my machine, mostly due to not needing to execute a new program every time.
I have a solution for one critical scenario (for which I struggled a lot )with union in HQL .
e.g. Instead of not working :-
select i , j from A a , (select i , j from B union select i , j from C) d where a.i = d.i
OR
select i , j from A a JOIN (select i , j from B union select i , j from C) d on a.i = d.i
YOU could do in Hibernate HQL ->
Query q1 =session.createQuery(select i , j from A a JOIN B b on a.i = b.i)
List l1 = q1.list();
Query q2 = session.createQuery(select i , j from A a JOIN C b on a.i = b.i)
List l2 = q2.list();
then u can add both list ->
l1.addAll(l2);
Why noy just use the theme styles in the table? i.e.
<table>
<thead class="ui-widget-header">
<tr>
<th>Id</th>
<th>Description</th>
</td>
</thead>
<tbody class="ui-widget-content">
<tr>
<td>...</td>
<td>...</td>
</tr>
.
.
.
</tbody>
</table>
And you don't need to use any code...
Most of the time you would create a list in groovy rather than an array. You could do it like this:
names = ["lucas", "Fred", "Mary"]
Alternately, if you did not want to quote everything like you did in the ruby example, you could do this:
names = "lucas Fred Mary".split()
For me on Windows 10: C:\Users\Paul\AppData\Local\GitHub\PortableGit_624c8416ee51e205b3f892d1d904e06e6f3c57c8\mingw32\bin\git.exe
If you want to check the total line of all the files in a directory ,you can use find and wc:
find . -type f -exec wc -l {} +
Complement with an additional example, you can access all job parameters in JavaConfig class:
@Bean
@StepScope
public ItemStreamReader<GenericMessage> reader(@Value("#{jobParameters}") Map<String,Object> jobParameters){
....
}
This is pretty simple here is an example
Add your command code here like:
if (cmd === `!dm`) {
let dUser =
message.guild.member(message.mentions.users.first()) ||
message.guild.members.get(args[0]);
if (!dUser) return message.channel.send("Can't find user!");
if (!message.member.hasPermission('ADMINISTRATOR'))
return message.reply("You can't you that command!");
let dMessage = args.join(' ').slice(22);
if (dMessage.length < 1) return message.reply('You must supply a message!');
dUser.send(`${dUser} A moderator from WP Coding Club sent you: ${dMessage}`);
message.author.send(
`${message.author} You have sent your message to ${dUser}`
);
}
If libncurses is not installed then install it and try again.
sudo apt-get install libncurses5:i386
or sudo apt-get install libncurses5
for 64 bit binaries
Also install the collection of libraries by using this command
sudo apt-get install ia32-libs
I have found the answer to my question.
client.DefaultRequestHeaders.Add("X-Version","1");
That should add a custom header to your request
In C, there's no (real, distinct type of) strings. Every C "string" is an array of chars, zero terminated.
Therefore, to extract a character c at index i from string your_string, just use
char c = your_string[i];
Index is base 0 (first character is your_string[0], second is your_string[1]...).
I was able to convert using below method for my WebAPI:
[HttpPost]
public HttpResponseMessage Post(dynamic item) // Passing parameter as dynamic
{
JArray itemArray = item["Region"]; // You need to add JSON.NET library
JObject obj = itemArray[0] as JObject; // Converting from JArray to JObject
Region objRegion = obj.ToObject<Region>(); // Converting to Region object
}
I've tried a pretty ugly solution but it fixed my problem.
var tabPressed = false;
$(document).keydown(function (e) {
// Listening tab button.
if (e.which == 9) {
tabPressed = true;
}
});
$(document).on('focus', '.select2', function() {
if (tabPressed) {
tabPressed = false;
$(this).siblings('select').select2('open');
}
});
I made the mistake of opening a BufferedReader like:
File f = new File("somefile.txt");
BufferedReader br = new BufferedReader(new FileReader(f));
...and of course I could not execute the f.delete()
because I wrapped the
FileReader instead of instantiating its own variable where I could explicitly close it. Duh...
Once I coded:
File f = new File("somefile.txt");
FileReader fread = new FileReader(f);
BufferedReader br = new BufferedReader(fread);
I could issue a br.close(); br=null; fread.close(); fread=null;
and the f.delete()
worked fine.
The main difference between the two is where it is stored and how it is accessed.
$.fn.attr
stores the information directly on the element in attributes which are publicly visible upon inspection, and also which are available from the element's native API.
$.fn.data
stores the information in a ridiculously obscure place. It is located in a closed over local variable called data_user
which is an instance of a locally defined function Data. This variable is not accessible from outside of jQuery directly.
Data set with attr()
$(element).attr('data-name')
element.getAttribute('data-name')
,data-name
also accessible from $(element).data(name)
and element.dataset['name']
and element.dataset.name
Data set with .data()
.data(name)
.attr()
or anywhere elseA comprehensive list of browser versions supporting the async
parameter is available here
If you are using windows 10 or windows server 2012, the steps to change the java runtime version is this:
Update: This answer has led to the development of ng2-completer
an Angular2 autocomplete component.
This is the list of existing autocomplete components for Angular2:
Credit goes to @dan-cancro for coming up with the idea
Keeping the original answer for those who wish to create their own directive:
To display autocomplete list we first need an attribute directive that will return the list of suggestions based on the input text and then display them in a dropdown. The directive has 2 options to display the list:
It looks to me that 2nd way is a better choice as it uses angular 2 core mechanisms instead of bypassing them by working directly with the DOM and therefore I'll use this method.
This is the directive code:
"use strict";
import {Directive, DynamicComponentLoader, Input, ComponentRef, Output, EventEmitter, OnInit, ViewContainerRef} from "@angular/core";
import {Promise} from "es6-promise";
import {AutocompleteList} from "./autocomplete-list";
@Directive({
selector: "[ng2-autocomplete]", // The attribute for the template that uses this directive
host: {
"(keyup)": "onKey($event)" // Liten to keyup events on the host component
}
})
export class AutocompleteDirective implements OnInit {
// The search function should be passed as an input
@Input("ng2-autocomplete") public search: (term: string) => Promise<Array<{ text: string, data: any }>>;
// The directive emits ng2AutocompleteOnSelect event when an item from the list is selected
@Output("ng2AutocompleteOnSelect") public selected = new EventEmitter();
private term = "";
private listCmp: ComponentRef<AutocompleteList> = undefined;
private refreshTimer: any = undefined;
private searchInProgress = false;
private searchRequired = false;
constructor( private viewRef: ViewContainerRef, private dcl: DynamicComponentLoader) { }
/**
* On key event is triggered when a key is released on the host component
* the event starts a timer to prevent concurrent requests
*/
public onKey(event: any) {
if (!this.refreshTimer) {
this.refreshTimer = setTimeout(
() => {
if (!this.searchInProgress) {
this.doSearch();
} else {
// If a request is in progress mark that a new search is required
this.searchRequired = true;
}
},
200);
}
this.term = event.target.value;
if (this.term === "" && this.listCmp) {
// clean the list if the search term is empty
this.removeList();
}
}
public ngOnInit() {
// When an item is selected remove the list
this.selected.subscribe(() => {
this.removeList();
});
}
/**
* Call the search function and handle the results
*/
private doSearch() {
this.refreshTimer = undefined;
// if we have a search function and a valid search term call the search
if (this.search && this.term !== "") {
this.searchInProgress = true;
this.search(this.term)
.then((res) => {
this.searchInProgress = false;
// if the term has changed during our search do another search
if (this.searchRequired) {
this.searchRequired = false;
this.doSearch();
} else {
// display the list of results
this.displayList(res);
}
})
.catch(err => {
console.log("search error:", err);
this.removeList();
});
}
}
/**
* Display the list of results
* Dynamically load the list component if it doesn't exist yet and update the suggestions list
*/
private displayList(list: Array<{ text: string, data: any }>) {
if (!this.listCmp) {
this.dcl.loadNextToLocation(AutocompleteList, this.viewRef)
.then(cmp => {
// The component is loaded
this.listCmp = cmp;
this.updateList(list);
// Emit the selectd event when the component fires its selected event
(<AutocompleteList>(this.listCmp.instance)).selected
.subscribe(selectedItem => {
this.selected.emit(selectedItem);
});
});
} else {
this.updateList(list);
}
}
/**
* Update the suggestions list in the list component
*/
private updateList(list: Array<{ text: string, data: any }>) {
if (this.listCmp) {
(<AutocompleteList>(this.listCmp.instance)).list = list;
}
}
/**
* remove the list component
*/
private removeList() {
this.searchInProgress = false;
this.searchRequired = false;
if (this.listCmp) {
this.listCmp.destroy();
this.listCmp = undefined;
}
}
}
The directive dynamically loads a dropdown component, this is a sample of such a component using bootstrap 4:
"use strict";
import {Component, Output, EventEmitter} from "@angular/core";
@Component({
selector: "autocomplete-list",
template: `<div class="dropdown-menu search-results">
<a *ngFor="let item of list" class="dropdown-item" (click)="onClick(item)">{{item.text}}</a>
</div>`, // Use a bootstrap 4 dropdown-menu to display the list
styles: [".search-results { position: relative; right: 0; display: block; padding: 0; overflow: hidden; font-size: .9rem;}"]
})
export class AutocompleteList {
// Emit a selected event when an item in the list is selected
@Output() public selected = new EventEmitter();
public list;
/**
* Listen for a click event on the list
*/
public onClick(item: {text: string, data: any}) {
this.selected.emit(item);
}
}
To use the directive in another component you need to import the directive, include it in the components directives and provide it with a search function and event handler for the selection:
"use strict";
import {Component} from "@angular/core";
import {AutocompleteDirective} from "../component/ng2-autocomplete/autocomplete";
@Component({
selector: "my-cmp",
directives: [AutocompleteDirective],
template: `<input class="form-control" type="text" [ng2-autocomplete]="search()" (ng2AutocompleteOnSelect)="onItemSelected($event)" autocomplete="off">`
})
export class MyComponent {
/**
* generate a search function that returns a Promise that resolves to array of text and optionally additional data
*/
public search() {
return (filter: string): Promise<Array<{ text: string, data: any }>> => {
// do the search
resolve({text: "one item", data: null});
};
}
/**
* handle item selection
*/
public onItemSelected(selected: { text: string, data: any }) {
console.log("selected: ", selected.text);
}
}
Update: code compatible with angular2 rc.1
This is a two-step process:
you need to create a login to SQL Server for that user, based on its Windows account
CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
you need to grant this login permission to access a database:
USE (your database)
CREATE USER (username) FOR LOGIN (your login name)
Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader
database role to read all tables.
USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'
I've tried everything suggested here but didn't work for me. So in case I can help anyone with a similar issue, every single tutorial I've checked is not updated to work with version 4.
Here is what I've done to make it work
import React from 'react';
import App from './App';
import ReactDOM from 'react-dom';
import {
HashRouter,
Route
} from 'react-router-dom';
ReactDOM.render((
<HashRouter>
<div>
<Route path="/" render={()=><App items={temasArray}/>}/>
</div>
</HashRouter >
), document.getElementById('root'));
That's the only way I have managed to make it work without any errors or warnings.
In case you want to pass props to your component for me the easiest way is this one:
<Route path="/" render={()=><App items={temasArray}/>}/>
public class Student implements Comparable<Student> {
private int sid;
private String sname;
public Student(int sid, String sname) {
super();
this.sid = sid;
this.sname = sname;
}
public int getSid() {
return sid;
}
public void setSid(int sid) {
this.sid = sid;
}
public String getSname() {
return sname;
}
public void setSname(String sname) {
this.sname = sname;
}
@Override
public String toString() {
return "Student [sid=" + sid + ", sname=" + sname + "]";
}
public int compareTo(Student o) {
if (this.getSname().compareTo(o.getSname()) > 1) {
return toString().compareTo(o.getSname());
} else if (this.getSname().compareTo(o.getSname()) < 1) {
return toString().compareTo(o.getSname());
}
return 0;
}
}
When you import a module, yo have access to plenty of information. Check out dir(a_module)
. As for the path, there is a dunder for that: a_module.__path__
. You can also just print the module itself.
>>> import a_module
>>> print(dir(a_module))
['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__']
>>> print(a_module.__path__)
['/.../.../a_module']
>>> print(a_module)
<module 'a_module' from '/.../.../a_module/__init__.py'>
You can't have optional arguments that default to a certain value in Java. The nearest thing to what you are talking about is java varargs whereby you can pass an arbitrary number of arguments (of the same type) to a method.
If you need to set the mirror in a non-interactive way (for example doing an rbundler install in a deploy script) you can do it in this way:
First manually run:
chooseCRANmirror()
Pick the mirror number that is best for you and remember it. Then to automate the selection:
R -e 'chooseCRANmirror(graphics=FALSE, ind=87);library(rbundler);bundle()'
Where 87 is the number of the mirror you would like to use. This snippet also installs the rbundle for you. You can omit that if you like.
Look at the following:
map(multilambda x:
y=x+1
return y
, [1,2,3])
Is this a lambda returning (y, [1,2,3])
(thus map only gets one parameter, resulting in an error)? Or does it return y
? Or is it a syntax error, because the comma on the new line is misplaced? How would Python know what you want?
Within the parens, indentation doesn't matter to python, so you can't unambiguously work with multilines.
This is just a simple one, there's probably more examples.
Yes, you can use regular expressions
in C#.
Using regular expressions with C#
:
using System.Text.RegularExpressions;
string your_String = "Hello@Hello&Hello(Hello)";
string my_String = Regex.Replace(your_String, @"[^0-9a-zA-Z]+", ",");
[update 2015-09-28] Now Google lets you add custom domains (including naked domains) and setup SSL without the need of Google Apps. For details refer to here: https://cloud.google.com/appengine/docs/using-custom-domains-and-ssl?hl=en
I just discovered today (as of 2014-04-11) a new custom domain settings page is available from Google Developers Console:
1. Go to https://console.developers.google.com/project
2. Click on your project
3. On the left click "App Engine"
4. Click "Settings"
There you go! You can configure custom domain without the need of Google App account!
For that

Issue is that it is failed to decrypt 256 bits of encryption.
does it matter? people are generally smart enough to interpret messages correctly, if they aren't you probably shouldn't let them access your repository anyway!
It's because of the way NOT IN works.
To avoid these headaches (and for a faster query in many cases), I always prefer NOT EXISTS:
SELECT *
FROM Table1 t1
WHERE NOT EXISTS (
SELECT *
FROM Table2 t2
WHERE t1.MAKE = t2.MAKE
AND t1.MODEL = t2.MODEL
AND t1.[Serial Number] = t2.[serial number]);
Yes, encryption add some load to your cpu, but if your cpu is not ancient that should not affect as much as you say.
If you enable compression for SSH, SCP is actually faster than FTP despite the SSH encryption (if I remember, twice as fast as FTP for the files I tried). I haven't actually used SFTP, but I believe it uses SCP for the actual file transfer. So please try this and let us know :-)
This is likely due to your app exceeding the 65k method count, thus causing a dex error. There is no solution, other than enabling multidexing in your app.
your nested for loop
for(int j = 0; j < array2.size(); i++){
is infinite as j will always equal to zero, on the other hand, i will be increased at will in this loop. You get OutOfBoundaryException when i is larger than plusArray.size()
To return only one row use LIMIT 1
:
SELECT *
FROM tbl_foo
WHERE name = 'sarmen'
LIMIT 1
It doesn't make sense to say 'first row' or 'last row' unless you have an ORDER BY
clause. Assuming you add an ORDER BY
clause then you can use LIMIT in the following ways:
LIMIT 1
.LIMIT 1, 1
.LIMIT 1
.The latest dwr (http://directwebremoting.org/dwr/index.html) has ajax file uploads, complete with examples and nice stuff for users (like progress indicators and such).
It looks pretty nifty and dwr is fairly easy to use in general so this will be pretty good as well.
You need to use \n
inside quotes.
document.getElementById("address_box").value = (title + "\n" + address + "\n" + address2 + "\n" + address3 + "\n" + address4)
\n
is called a EOL
or line-break
, \n
is a common EOL
marker and is commonly refereed to as LF
or line-feed
, it is a special ASCII
character
I get the error in another situation, and here are the problem and the solution:
I have 2 classes derived from a same base class named LevledItem:
public partial class Team : LeveledItem
{
//Everything is ok here!
}
public partial class Story : LeveledItem
{
//Everything is ok here!
}
But in their DbContext, I copied some code but forget to change one of the class name:
public class MFCTeamDbContext : DbContext
{
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
//Other codes here
modelBuilder.Entity<LeveledItem>()
.Map<Team>(m => m.Requires("Type").HasValue(ItemType.Team));
}
public class ProductBacklogDbContext : DbContext
{
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
//Other codes here
modelBuilder.Entity<LeveledItem>()
.Map<Team>(m => m.Requires("Type").HasValue(ItemType.Story));
}
Yes, the second Map< Team> should be Map< Story>. And it cost me half a day to figure it out!
' \r ' means carriage return.
The \r means nothing special as a consequence.For character-mode terminals (typically emulating even-older printing ones as above), in raw mode, \r and \n act similarly (except both in terms of the cursor, as there is no carriage or roller . Historically a \n was used to move the carriage down, while the \r was used to move the carriage back to the left side of the screen.
You can disable them in your browser.
Type about:config
in the Firefox address bar and find security.csp.enable
and set it to false
.
You can install the extension called Disable Content-Security-Policy
to disable CSP.
Check your SMTP settings in your php.ini file. Your host should have some documentation about what credentials to use. Perhaps you can check your error log file, it might have more information available.
SELECT *, COUNT(*) FROM my_table
is not what you want, and it's not really valid SQL, you have to group by all the columns that's not an aggregate.
You'd want something like
SELECT somecolumn,someothercolumn, COUNT(*)
FROM my_table
GROUP BY somecolumn,someothercolumn
If you're using PHP 5.5 or PHP 7 above, you may want to use:
function isTodayWeekend() {
return in_array(date("l"), ["Saturday", "Sunday"]);
}
and it will return "true" if today is weekend and "false" if not.

The simplest answer, assuming you don't mind the vagaries and variations in format between different platforms, is the standard %p
notation.
The C99 standard (ISO/IEC 9899:1999) says in §7.19.6.1 ¶8:
p
The argument shall be a pointer tovoid
. The value of the pointer is converted to a sequence of printing characters, in an implementation-defined manner.
(In C11 — ISO/IEC 9899:2011 — the information is in §7.21.6.1 ¶8.)
On some platforms, that will include a leading 0x
and on others it won't, and the letters could be in lower-case or upper-case, and the C standard doesn't even define that it shall be hexadecimal output though I know of no implementation where it is not.
It is somewhat open to debate whether you should explicitly convert the pointers with a (void *)
cast. It is being explicit, which is usually good (so it is what I do), and the standard says 'the argument shall be a pointer to void
'. On most machines, you would get away with omitting an explicit cast. However, it would matter on a machine where the bit representation of a char *
address for a given memory location is different from the 'anything else pointer' address for the same memory location. This would be a word-addressed, instead of byte-addressed, machine. Such machines are not common (probably not available) these days, but the first machine I worked on after university was one such (ICL Perq).
If you aren't happy with the implementation-defined behaviour of %p
, then use C99 <inttypes.h>
and uintptr_t
instead:
printf("0x%" PRIXPTR "\n", (uintptr_t)your_pointer);
This allows you to fine-tune the representation to suit yourself. I chose to have the hex digits in upper-case so that the number is uniformly the same height and the characteristic dip at the start of 0xA1B2CDEF
appears thus, not like 0xa1b2cdef
which dips up and down along the number too. Your choice though, within very broad limits. The (uintptr_t)
cast is unambiguously recommended by GCC when it can read the format string at compile time. I think it is correct to request the cast, though I'm sure there are some who would ignore the warning and get away with it most of the time.
Kerrek asks in the comments:
I'm a bit confused about standard promotions and variadic arguments. Do all pointers get standard-promoted to void*? Otherwise, if
int*
were, say, two bytes, andvoid*
were 4 bytes, then it'd clearly be an error to read four bytes from the argument, non?
I was under the illusion that the C standard says that all object pointers must be the same size, so void *
and int *
cannot be different sizes. However, what I think is the relevant section of the C99 standard is not so emphatic (though I don't know of an implementation where what I suggested is true is actually false):
§6.2.5 Types
¶26 A pointer to void shall have the same representation and alignment requirements as a pointer to a character type.39) Similarly, pointers to qualified or unqualified versions of compatible types shall have the same representation and alignment requirements. All pointers to structure types shall have the same representation and alignment requirements as each other. All pointers to union types shall have the same representation and alignment requirements as each other. Pointers to other types need not have the same representation or alignment requirements.
39) The same representation and alignment requirements are meant to imply interchangeability as arguments to functions, return values from functions, and members of unions.
(C11 says exactly the same in the section §6.2.5, ¶28, and footnote 48.)
So, all pointers to structures must be the same size as each other, and must share the same alignment requirements, even though the structures the pointers point at may have different alignment requirements. Similarly for unions. Character pointers and void pointers must have the same size and alignment requirements. Pointers to variations on int
(meaning unsigned int
and signed int
) must have the same size and alignment requirements as each other; similarly for other types. But the C standard doesn't formally say that sizeof(int *) == sizeof(void *)
. Oh well, SO is good for making you inspect your assumptions.
The C standard definitively does not require function pointers to be the same size as object pointers. That was necessary not to break the different memory models on DOS-like systems. There you could have 16-bit data pointers but 32-bit function pointers, or vice versa. This is why the C standard does not mandate that function pointers can be converted to object pointers and vice versa.
Fortunately (for programmers targetting POSIX), POSIX steps into the breach and does mandate that function pointers and data pointers are the same size:
§2.12.3 Pointer Types
All function pointer types shall have the same representation as the type pointer to void. Conversion of a function pointer to
void *
shall not alter the representation. Avoid *
value resulting from such a conversion can be converted back to the original function pointer type, using an explicit cast, without loss of information.Note: The ISO C standard does not require this, but it is required for POSIX conformance.
So, it does seem that explicit casts to void *
are strongly advisable for maximum reliability in the code when passing a pointer to a variadic function such as printf()
. On POSIX systems, it is safe to cast a function pointer to a void pointer for printing. On other systems, it is not necessarily safe to do that, nor is it necessarily safe to pass pointers other than void *
without a cast.
This works for me:
RewriteCond %{HTTP_HOST} ^(?!www.domain.com).*$ [NC]
RewriteRule ^(.*)$ http://www.domain.com$1 [R=301,L]
I use the look-ahead pattern (?!www.domain.com)
to exclude the www
subdomain when redirecting all domains to the www
subdomain in order to avoid an infinite redirect loop in Apache.
It depends where you put this initialisation.
If the array is static as in
char array[100] = {0};
int main(void)
{
...
}
then it is the compiler that reserves the 100 0 bytes in the data segement of the program. In this case you could have omitted the initialiser.
If your array is auto, then it is another story.
int foo(void)
{
char array[100] = {0};
...
}
In this case at every call of the function foo you will have a hidden memset.
The code above is equivalent to
int foo(void)
{
char array[100];
memset(array, 0, sizeof(array));
....
}
and if you omit the initializer your array will contain random data (the data of the stack).
If your local array is declared static like in
int foo(void)
{
static char array[100] = {0};
...
}
then it is technically the same case as the first one.
Another example with a struct :
package types
import "fmt"
type MyType struct {
Id int
Name string
}
func (t MyType) String() string {
return fmt.Sprintf(
"[%d : %s]",
t.Id,
t.Name)
}
Be careful when using it,
concatenation with '+' doesn't compile :
t := types.MyType{ 12, "Blabla" }
fmt.Println(t) // OK
fmt.Printf("t : %s \n", t) // OK
//fmt.Println("t : " + t) // Compiler error !!!
fmt.Println("t : " + t.String()) // OK if calling the function explicitly
private static String getMessageDigest(String message, String algorithm) {
MessageDigest digest;
try {
digest = MessageDigest.getInstance(algorithm);
byte data[] = digest.digest(message.getBytes("UTF-8"));
return convertByteArrayToHexString(data);
} catch (NoSuchAlgorithmException | UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
You can call above method with different algorithms like below.
getMessageDigest(message, "MD5");
getMessageDigest(message, "SHA-256");
getMessageDigest(message, "SHA-1");
You can refer this link for complete application.
You need to Tomcat Dependency and also extend your Application Class from extends SpringBootServletInitializer
@SpringBootApplication
public class App extend SpringBootServletInitializer
{
public static void main( String[] args )
{
SpringApplication.run(App.class, "hello");
}
}
An important part of using a key down on tab is knowing that tab will always try to do something already, don't forget to "return false" at the end.
Here is what I did. I have a function that runs on .blur and a function that swaps where my form focus is. Basically it adds an input to the end of the form and goes there while running calculations on blur.
$(this).children('input[type=text]').blur(timeEntered).keydown(function (e) {
var code = e.keyCode || e.which;
if (code == "9") {
window.tabPressed = true;
// Here is the external function you want to call, let your external
// function handle all your custom code, then return false to
// prevent the tab button from doing whatever it would naturally do.
focusShift($(this));
return false;
} else {
window.tabPressed = false;
}
// This is the code i want to execute, it might be different than yours
function focusShift(trigger) {
var focalPoint = false;
if (tabPressed == true) {
console.log($(trigger).parents("td").next("td"));
focalPoint = $(trigger).parents("td").next("td");
}
if (focalPoint) {
$(focalPoint).trigger("click");
}
}
});
Get the names and default values of a function’s arguments. A tuple of four things is returned: (args, varargs, varkw, defaults). args is a list of the argument names (it may contain nested lists). varargs and varkw are the names of the * and ** arguments or None. defaults is a tuple of default argument values or None if there are no default arguments; if this tuple has n elements, they correspond to the last n elements listed in args.
Changed in version 2.6: Returns a named tuple ArgSpec(args, varargs, keywords, defaults).

You have to call 2 functions for this:
First: for excuting the commands you have implemented in onNavigationItemSelected
listener:
onNavigationItemSelected(navigationView.getMenu().getItem(R.id.nav_camera));
Second: for changing the state of the navigation drawer menu item to selected (or checked):
navigationView.setCheckedItem(R.id.nav_camera);
I called both functions and it worked for me.
try this
string htmlBody = ParseHmlBody(dtViewDetails.Rows[0]["Body"].ToString());
private string ParseHmlBody(string html)
{
string body = string.Empty;
try
{
var htmlDoc = new HtmlDocument();
htmlDoc.LoadHtml(html);
var htmlBody = htmlDoc.DocumentNode.SelectSingleNode("//body");
body = htmlBody.OuterHtml;
}
catch (Exception ex)
{
dalPendingOrders.LogMessage("Error in ParseHmlBody" + ex.Message);
}
return body;
}
I found this script on this site and it seems to work quite well.
On your local copy, modify your .git/config file and add your web server as a remote:
[remote "production"]
url = username@webserver:/path/to/htdocs/.git
On the server, replace .git/hooks/post-update with this file (in the answer below)
Add execute access to the file (again, on the server):
chmod +x .git/hooks/post-update
Now, just locally push to your web server and it should automatically update the working copy:
git push production
This is my solution:
<video id="playVideo" width="680" height="400" controls="controls">
<source id="sourceVideo" src="{{video.videoHigh}}" type="video/mp4">
</video>
<br />
<button class="btn btn-warning" id="{{video.videoHigh}}" onclick="changeSource(this)">HD</button>
<button class="btn btn-warning" id="{{video.videoLow}}" onclick="changeSource(this)">Regular</button>
<script type="text/javascript">
var getVideo = document.getElementById("playVideo");
var getSource = document.getElementById("sourceVideo");
function changeSource(vid) {
var geturl = vid.id;
getSource .setAttribute("src", geturl);
getVideo .load()
getVideo .play();
getVideo .volume = 0.5;
}
</script>
If want to totally delete it use del
:
del your_variable
Or otherwise, to make the value None
:
your_variable = None
If it's a mutable iterable (lists, sets, dictionaries, etc, but not tuples because they're immutable), you can make it empty like:
your_variable.clear()
Then your_variable
will be empty
Assuming that you would really want your loop to run 24/7 as a background service
For a solution that doesn't involve injecting your code with libraries, you can simply create a service template, since you are using linux:
[Unit]
Description = <Your service description here>
After = network.target # Assuming you want to start after network interfaces are made available
[Service]
Type = simple
ExecStart = python <Path of the script you want to run>
User = # User to run the script as
Group = # Group to run the script as
Restart = on-failure # Restart when there are errors
SyslogIdentifier = <Name of logs for the service>
RestartSec = 5
TimeoutStartSec = infinity
[Install]
WantedBy = multi-user.target # Make it accessible to other users
Place that file in your daemon service folder (usually /etc/systemd/system/
), in a *.service
file, and install it using the following systemctl commands (will likely require sudo privileges):
systemctl enable <service file name without .service extension>
systemctl daemon-reload
systemctl start <service file name without .service extension>
You can then check that your service is running by using the command:
systemctl | grep running
NSURLSession introduced in iOS 7, is the recommended SDK way of downloading a file. No need to import 3rd party libraries.
NSURL *url = [NSURL URLWithString:@"http://www.something.com/file"];
NSURLRequest *downloadRequest = [NSURLRequest requestWithURL:url];
NSURLSessionConfiguration *sessionConfig = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *urlSession = [NSURLSession sessionWithConfiguration:sessionConfig delegate:self delegateQueue:nil];
self.downloadTask = [self.urlSession downloadTaskWithRequest:downloadRequest];
[self.downloadTask resume];
You can then use the NSURLSessionDownloadDelegate delegate methods to monitor errors, download completion, download progress etc... There are inline block completion handler callback methods too if you prefer. Apples docs explain when you need to use one over the other.
Have a read of these articles:
Error 'Duplicate entry '338620-7' for key 2' on query. Default database
For this error :
set global sql_slave_skip_counter=1;
start slave;
show slave status\G
This worked for me
For posterity, I think this is quicker:
a = np.array([np.array(list()) for _ in y])
You might even be able to pass in a generator (i.e. [] -> ()), in which case the inner list is never fully stored in memory.
Responding to comment below:
>>> import numpy as np
>>> y = range(10)
>>> a = np.array([np.array(list) for _ in y])
>>> a
array([array(<type 'list'>, dtype=object),
array(<type 'list'>, dtype=object),
array(<type 'list'>, dtype=object),
array(<type 'list'>, dtype=object),
array(<type 'list'>, dtype=object),
array(<type 'list'>, dtype=object),
array(<type 'list'>, dtype=object),
array(<type 'list'>, dtype=object),
array(<type 'list'>, dtype=object),
array(<type 'list'>, dtype=object)], dtype=object)
Since I've already been where you are right now, I think I can "answer" you.
The fact is there is no easy way to make a GUI. GUI's are highly dependent on platform and OS specific code, that's why you should start reading your target platform/OS documentation on window management APIs. The good thing is: there are plenty of libraries that address these limitations and abstract architecture differences into a single multi-platform API. Those suggested before, GTK and Qt, are some of these libraries.
But even these are a little too complicated, since lots of new concepts, data types, namespaces and classes are introduced, all at once. For this reason, they use to come bundled with some GUI WYSIWYG editor. They pretty much make programming software with GUIs possible.
To sum it up, there are also non free "environments" for GUI development such as Visual Studio from Microsoft. For those with Delphi experience backgrounds, Visual Studio may be more familiar. There are also free alternatives to the full Visual Studio environment supplied from Microsoft: Visual Studio Express, which is more than enough for starting on GUI development.
This can be installed via conda with the command conda install -c anaconda python=3.7
as per https://anaconda.org/anaconda/python.
Though not all packages support 3.7 yet, running conda update --all
may resolve some dependency failures.
You need to run
git fetch
To get all changes and then you will not receive message with "your branch is ahead".
In my case, the files were already copied, I found the easiest way to follow the steps in this guide: https://www.ryadel.com/en/exporting-importing-app-pools-and-websites-configuration-between-multiple-iis-instances/
I exported AppPools/Websites, copied the xml files to the destination server and Imported AppPools then Websites. Worked very well. This is also another excellent option for this question.
