I was looking for an ExecutorService that can interrupt all timed out Runnables executed by it, but found none. After a few hours I created one as below. This class can be modified to enhance robustness.
public class TimedExecutorService extends ThreadPoolExecutor {
long timeout;
public TimedExecutorService(int numThreads, long timeout, TimeUnit unit) {
super(numThreads, numThreads, 0L, TimeUnit.MILLISECONDS, new ArrayBlockingQueue<Runnable>(numThreads + 1));
this.timeout = unit.toMillis(timeout);
}
@Override
protected void beforeExecute(Thread thread, Runnable runnable) {
Thread interruptionThread = new Thread(new Runnable() {
@Override
public void run() {
try {
// Wait until timeout and interrupt this thread
Thread.sleep(timeout);
System.out.println("The runnable times out.");
thread.interrupt();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
});
interruptionThread.start();
}
}
Usage:
public static void main(String[] args) {
Runnable abcdRunnable = new Runnable() {
@Override
public void run() {
System.out.println("abcdRunnable started");
try {
Thread.sleep(20000);
} catch (InterruptedException e) {
// logger.info("The runnable times out.");
}
System.out.println("abcdRunnable ended");
}
};
Runnable xyzwRunnable = new Runnable() {
@Override
public void run() {
System.out.println("xyzwRunnable started");
try {
Thread.sleep(20000);
} catch (InterruptedException e) {
// logger.info("The runnable times out.");
}
System.out.println("xyzwRunnable ended");
}
};
int numThreads = 2, timeout = 5;
ExecutorService timedExecutor = new TimedExecutorService(numThreads, timeout, TimeUnit.SECONDS);
timedExecutor.execute(abcdRunnable);
timedExecutor.execute(xyzwRunnable);
timedExecutor.shutdown();
}
using Linq would be:
listOfCompany.Where(c=> c.id == 1).FirstOrDefault().Name = "Whatever Name";
UPDATE
This can be simplified to be...
listOfCompany.FirstOrDefault(c=> c.id == 1).Name = "Whatever Name";
For multiple items (condition is met by multiple items):
listOfCompany.Where(c=> c.id == 1).ToList().ForEach(cc => cc.Name = "Whatever Name");
Make your activity A in manifest file: launchMode = "singleInstance"
When the user clicks new, do FirstActivity.fa.finish();
and call the new Intent.
When the user clicks modify, call the new Intent or simply finish activity B.
FIRST WAY
In your first activity, declare one Activity object
like this,
public static Activity fa;
onCreate()
{
fa = this;
}
now use that object in another Activity
to finish first-activity like this,
onCreate()
{
FirstActivity.fa.finish();
}
SECOND WAY
While calling your activity FirstActivity
which you want to finish as soon as you move on,
You can add flag while calling FirstActivity
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
But using this flag the activity will get finished evenif you want it not to. and sometime onBack
if you want to show the FirstActivity
you will have to call it using intent.
You can replace 0
with NA
only in numeric fields (i.e. excluding things like factors), but it works on a column-by-column basis:
col[col == 0 & is.numeric(col)] <- NA
With a function, you can apply this to your whole data frame:
changetoNA <- function(colnum,df) {
col <- df[,colnum]
if (is.numeric(col)) { #edit: verifying column is numeric
col[col == -1 & is.numeric(col)] <- NA
}
return(col)
}
df <- data.frame(sapply(1:5, changetoNA, df))
Although you could replace the 1:5
with the number of columns in your data frame, or with 1:ncol(df)
.

Update 10/11/2020 to reflect the latest brew changes.
Brew
already provide a command to uninstall itself (this will remove everything you installed with Homebrew):
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
If you failed to run this command due to permission (like run as second user), run again with sudo
Then you can install again:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Encode string as unicode.

If you have android studio installed then you might want to try:
export PATH="$PATH:/home/<username>/android-studio/gradle/<gradle-4.0>/bin"
This solved my problem.
This is not direct answer to the question, but since I got here when searching for my own answers, I'll share this here.
If you have tens or hundreds of millions of keys you have to match, the answers given here will cause Redis to be non responsive for significant amount of time (minutes?), and potentially crash because of memory consumption (be sure, background save will kick in in the middle of your operation).
The following approach is undeniably ugly, but I didn't find a better one. Atomicity is out of question here, in this case main goal is to keep Redis up and responsive 100% of the time. It will work perfectly if you have all your keys in one of databases and you don't need to match any pattern, but cannot use http://redis.io/commands/FLUSHDB because of it's blocking nature.
Idea is simple: write a script that runs in a loop and uses O(1) operation like http://redis.io/commands/SCAN or http://redis.io/commands/RANDOMKEY to get keys, checks if they match the pattern (if you need it) and http://redis.io/commands/DEL them one by one.
If there is a better way to do it, please let me know, I'll update the answer.
Example implementation with randomkey in Ruby, as a rake task, a non blocking substitute of something like redis-cli -n 3 flushdb
:
desc 'Cleanup redis'
task cleanup_redis: :environment do
redis = Redis.new(...) # connection to target database number which needs to be wiped out
counter = 0
while key = redis.randomkey
puts "Deleting #{counter}: #{key}"
redis.del(key)
counter += 1
end
end
Have you seen the book "Bioinformatics Programming using Python"? Looks like you're an exact member of its focus group.
If you're targeting HTML5 only you can use:
<input type="text" id="firstname" placeholder="First Name:" />
For non HTML5 browsers, I would build upon Floern's answer by using jQuery and make the javascript non-obtrusive. I would also use a class to define the blurred properties.
$(document).ready(function () {
//Set the initial blur (unless its highlighted by default)
inputBlur($('#Comments'));
$('#Comments').blur(function () {
inputBlur(this);
});
$('#Comments').focus(function () {
inputFocus(this);
});
})
Functions:
function inputFocus(i) {
if (i.value == i.defaultValue) {
i.value = "";
$(i).removeClass("blurredDefaultText");
}
}
function inputBlur(i) {
if (i.value == "" || i.value == i.defaultValue) {
i.value = i.defaultValue;
$(i).addClass("blurredDefaultText");
}
}
CSS:
.blurredDefaultText {
color:#888 !important;
}
Trick question: What kinds of parameters are passed by reference in Java?
It's amazing how many people still parrot the "primitives are passed by value, objects are passed by reference" mantra.
You can also use jq to track down the array within the returned json and then pipe that in to a second jq
call to get its length. Suppose it was in a property called records
, like {"records":[...]}
.
$ curl https://my-source-of-json.com/list | jq -r '.records' | jq length
2
$
It's in VS2012 - Specifically the 2-Arrow icon at the top of the solution explorer (Left/Right arrows, one above the other). This automatically jumps to the current file.
This icon is only visible if you've got Track Active Item in Solution Explorer
disabled.
"Allocation Failure" is cause of GC to kick is not correct. It is an outcome of GC operation.
GC kicks in when there is no space to allocate( depending on region minor or major GC is performed). Once GC is performed if space is freed good enough, but if there is not enough size it fails. Allocation Failure is one such failure. Below document have good explanation https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/g1_gc.html
For the better answer, you can use these lines of code. Here is the example maybe help you :
image = cv2.imread('/home/pictures/1.jpg')
plt.imshow(image)
plt.show()
In imread()
you can pass the directory .so you can also use str()
and +
to combine dynamic directories and fixed directory like this:
path = '/home/pictures/'
for i in range(2) :
image = cv2.imread(str(path)+'1.jpg')
plt.imshow(image)
plt.show()
Both are the same.
I've been down this road and eventually opted for a hardware data scope that does non-instrusive in-line monitoring. The software solutions that I tried didn't work for me. If you had a spare PC you could probably build one, albeit rather bulky. This software data scope may work, as might this, but I haven't tried either.
With num_rows()
you first perform the query, and then you can check how many rows you got. count_all_results()
on the other hand only gives you the number of rows your query would produce, but doesn't give you the actual resultset.
// num rows example
$this->db->select('*');
$this->db->where('whatever');
$query = $this->db->get('table');
$num = $query->num_rows();
// here you can do something with $query
// count all example
$this->db->where('whatever');
$num = $this->db->count_all_results('table');
// here you only have $num, no $query
'So from this discussion i am thinking this should be the code then.

What you have should work, unless ${STATUS}
is empty. It would probably be better to do:
if ! [ "${STATUS}" -eq 200 ] 2> /dev/null && [ "${STRING}" != "${VALUE}" ]; then
or
if [ "${STATUS}" != 200 ] && [ "${STRING}" != "${VALUE}" ]; then
It's hard to say, since you haven't shown us exactly what is going wrong with your script.
Personal opinion: never use [[
. It suppresses important error messages and is not portable to different shells.
There is often the tip to use 'echo.'
But that is slow, and it could fail with an error message, as cmd.exe will search first for a file named 'echo' (without extension) and only when the file doesn't exists it outputs an empty line.
You could use echo(
. This is approximately 20 times faster, and it works always. The only drawback could be that it looks odd.
More about the different ECHO:/\
variants is at DOS tips: ECHO. FAILS to give text or blank line.
(For those who stumble upon this from your search engine of choice)
This just recursively traces down the folder, so you don't need to duplicate your code twice. Also the OPs logic is needlessly complex.
Wscript.Echo "begin."
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objSuperFolder = objFSO.GetFolder(WScript.Arguments(0))
Call ShowSubfolders (objSuperFolder)
Wscript.Echo "end."
WScript.Quit 0
Sub ShowSubFolders(fFolder)
Set objFolder = objFSO.GetFolder(fFolder.Path)
Set colFiles = objFolder.Files
For Each objFile in colFiles
If UCase(objFSO.GetExtensionName(objFile.name)) = "PDF" Then
Wscript.Echo objFile.Name
End If
Next
For Each Subfolder in fFolder.SubFolders
ShowSubFolders(Subfolder)
Next

Use a BindingList and set the DataPropertyName-Property of the column.
Try the following:
...
private void BindGrid()
{
gvFilesOnServer.AutoGenerateColumns = false;
//create the column programatically
DataGridViewCell cell = new DataGridViewTextBoxCell();
DataGridViewTextBoxColumn colFileName = new DataGridViewTextBoxColumn()
{
CellTemplate = cell,
Name = "Value",
HeaderText = "File Name",
DataPropertyName = "Value" // Tell the column which property of FileName it should use
};
gvFilesOnServer.Columns.Add(colFileName);
var filelist = GetFileListOnWebServer().ToList();
var filenamesList = new BindingList<FileName>(filelist); // <-- BindingList
//Bind BindingList directly to the DataGrid, no need of BindingSource
gvFilesOnServer.DataSource = filenamesList
}
Another nice example using if
statements without =
assignment operations.
if (true || true && false); // is the same as:
if (true || (true && false)); // TRUE
and
if (true || true AND false); // is the same as:
if ((true || true) && false); // FALSE
because AND
has a lower precedence and thus ||
a higher precedence.
These are different in the cases of true, false, false
and true, true, false
.

I strongly suggest you to read this blog post which appeared on HackerNews recently: How HashMap works in Java
In short, the answer is
What will happen if two different HashMap key objects have same hashcode?
They will be stored in same bucket but no next node of linked list. And keys equals () method will be used to identify correct key value pair in HashMap.
Okay, the answers other people here gave me were close, but it didn't work. Here's what I did.
Doing this...
git reset --hard HEAD^
git status
...gave me the following status.
# On branch master
# Your branch and 'origin/master' have diverged,
# and have 3 and 3 different commit(s) each, respectively.
I then had to type in the same git reset
command several more times. Each time I did that, the message changed by one as you can see below.
> git reset --hard HEAD^
HEAD is now at [...truncated...]
> git status
# On branch master
# Your branch and 'origin/master' have diverged,
# and have 3 and 3 different commit(s) each, respectively.
> git reset --hard HEAD^
HEAD is now at [...truncated...]
> git status
# On branch master
# Your branch and 'origin/master' have diverged,
# and have 2 and 3 different commit(s) each, respectively.
> git reset --hard HEAD^
HEAD is now at [...truncated...]
> git status
# On branch master
# Your branch and 'origin/master' have diverged,
# and have 1 and 3 different commit(s) each, respectively.
> git reset --hard HEAD^
HEAD is now at [...truncated...]
> git status
# On branch master
# Your branch is behind 'origin/master' by 3 commits, and can be fast-forwarded.
At this point, I saw the status message changed, so I tried doing a git pull
, and that seemed to work:
> git pull
Updating 2df6af4..12bbd2f
Fast forward

app/views/truncated | 13 +++++++++++++
app/views/truncated | 2 +-
3 files changed, 20 insertions(+), 4 deletions(-)

So long story short, my commands came down to this:
git reset --hard HEAD^
git reset --hard HEAD^
git reset --hard HEAD^
git reset --hard HEAD^
git pull
Node.js doesn't use threading. According to its inventor that's a key feature. At the time of its invention, threads were slow, problematic, and difficult. Node.js was created as the result of an investigation into an efficient single-core alternative. Most Node.js enthusiasts still cite ye olde argument as if threads haven't been improved over the past 50 years.
As you know, Node.js is used to run JavaScript. The JavaScript language has also developed over the years. It now has ways of using multiple cores - i.e. what Threads do. So, via advancements in JavaScript, you can do some multi-core multi-tasking in your applications. user158 points out that Node.js is playing with it a bit. I don't know anything about that. But why wait for Node.js to approve of what JavaScript has to offer.
Google for JavaScript multi-threading instead of Node.js multi-threading. You'll find out about Web Workers, Promises, and other things.
Here are the steps to use ASP.NET MVC 5 in Visual Studio 2012:
These two will update:
If these upgrades did not update your web.config, then check out this useful page: upgrading from MVC4 to MVC5.
Arrays have numerical indexes. So,
a = new Array();
a['a1']='foo';
a['a2']='bar';
and
b = new Array(2);
b['b1']='foo';
b['b2']='bar';
are not adding elements to the array, but adding .a1
and .a2
properties to the a
object (arrays are objects too). As further evidence, if you did this:
a = new Array();
a['a1']='foo';
a['a2']='bar';
console.log(a.length); // outputs zero because there are no items in the array
Your third option:
c=['c1','c2','c3'];
is assigning the variable c
an array with three elements. Those three elements can be accessed as: c[0]
, c[1]
and c[2]
. In other words, c[0] === 'c1'
and c.length === 3
.
Javascript does not use its array functionality for what other languages call associative arrays where you can use any type of key in the array. You can implement most of the functionality of an associative array by just using an object in javascript where each item is just a property like this.
a = {};
a['a1']='foo';
a['a2']='bar';
It is generally a mistake to use an array for this purpose as it just confuses people reading your code and leads to false assumptions about how the code works.
I've came through a case recently where I've needed check value of checkbox when user clicked on button. The only proper way to do so is to use prop()
attribute.
var ansValue = $("#ans").prop('checked') ? $("#ans").val() : 0;
this worked in my case maybe someone will need it.
When I've tried .attr(':checked')
it returned checked
but I wanted boolean value and .val()
returned value of attribute value
.
Notepad++ provides 2 types of features:
Based on what you write, it seems what you want is auto-completion on function only + suggestion on arguments.
To do that, you just need to change a setting.
Settings
> Preferences...
> Auto-completion
Enable Auto-completion on each input
Function completion
and not Word completion
Function parameter hint on input
(if you have this option)On version 6.5.5 of Notepad++, I have this setting
Some documentation about auto-completion is available in Notepad++ Wiki.
I remove the characters '[',']' and do an split with ','
let array = stringObject.replace('[','').replace(']','').split(",").map(String);
Ref - JWT Structure and Security
It is important to note that JWT are used for authorization and not authentication.
So a JWT will be created for you only after you have been authenticated by the server by may be specifying the credentials. Once JWT has been created for all future interactions with server JWT can be used. So JWT tells that server that this user has been authenticated, let him access the particular resource if he has the role.
Information in the payload of the JWT is visible to everyone. There can be a "Man in the Middle" attack and the contents of the JWT can be changed. So we should not pass any sensitive information like passwords in the payload. We can encrypt the payload data if we want to make it more secure. If Payload is tampered with server will recognize it.
So suppose a user has been authenticated and provided with a JWT. Generated JWT has a claim specifying role of Admin. Also the Signature is generated with
This JWT is now tampered with and suppose the
role is changed to Super Admin
Then when the server receives this token it will again generate the signature using the secret key(which only the server has) and the payload. It will not match the signature
in the JWT. So the server will know that the JWT has been tampered with.
Just put a div and update the content...
<script>
function setvideo(src) {
document.getElementById('div_video').innerHTML = '<video autoplay controls id="video_ctrl" style="height: 100px; width: 100px;"><source src="'+src+'" type="video/mp4"></video>';
document.getElementById('video_ctrl').play();
}
</script>
<button onClick="setvideo('video1.mp4');">Video1</button>
<div id="div_video"> </div>
Its little tricky in android studio there is no default folder for all screen size you need to create but with little trick.
i cant post image here so if still having any problem. here is tutorial..
var string = string.split(",");
You can pass the inline handler the this
keyword, obtaining the element which fired the event.
like,
onclick="confirmSubmit(this);"
No need to store it anywhere. Just output the content with the appropriate content type.
<?php
header('Content-type: text/plain');
?>Hello, world.
Add content-disposition if you wish to trigger a download prompt.
header('Content-Disposition: attachment; filename="default-filename.txt"');
Try the following query:
collection.update(
{ _id: id },
{ $pull: { 'contact.phone': { number: '+1786543589455' } } }
);
It will find document with the given _id
and remove the phone +1786543589455
from its contact.phone
array.
You can use $unset
to unset the value in the array (set it to null
), but not to remove it completely.
In curl version 7.22.0 on Ubuntu and 7.24.0 on OSX the solution to not show progress but to show errors is to use both -s
(--silent
) and -S
(--show-error
) like so:
curl -sS http://google.com > temp.html
This works for both redirected output > /some/file
, piped output | less
and outputting directly to the terminal for me.
Update: Since curl 7.67.0 there is a new option --no-progress-meter
which does precisely this and nothing else, see clonejo's answer for more details.
I crammed everything into one line (bad I know) and had no troubles with it:
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"test"
ofType:@"html"]
isDirectory:NO]]];
I have a varargs-related fear, too:
If the caller passes in an explicit array to the method (as opposed to multiple parameters), you will receive a shared reference to that array.
If you need to store this array internally, you might want to clone it first to avoid the caller being able to change it later.
Object[] args = new Object[] { 1, 2, 3} ;
varArgMethod(args); // not varArgMethod(1,2,3);
args[2] = "something else"; // this could have unexpected side-effects
While this is not really different from passing in any kind of object whose state might change later, since the array is usually (in case of a call with multiple arguments instead of an array) a fresh one created by the compiler internally that you can safely use, this is certainly unexpected behaviour.
select parentTable.id from parentTable
left outer join childTable on (parentTable.id = childTable.parentTableID)
where childTable.id is null
As long as you specify a width on the element, it should wrap itself without needing anything else.
Similar situation. It was working. Then, I started to include pytables. At first view, no reason to errors. I decided to use another function, that has a domain constraint (elipse) and received the following error:
TypeError: 'numpy.float64' object cannot be interpreted as an integer
or
TypeError: 'numpy.float64' object is not iterable
The crazy thing: the previous function I was using, no code changed, started to return the same error. My intermediary function, already used was:
def MinMax(x, mini=0, maxi=1)
return max(min(x,mini), maxi)
The solution was avoid numpy
or math
:
def MinMax(x, mini=0, maxi=1)
x = [x_aux if x_aux > mini else mini for x_aux in x]
x = [x_aux if x_aux < maxi else maxi for x_aux in x]
return max(min(x,mini), maxi)
Then, everything calm again. It was like one library possessed max
and min

Here's the way doing it using jQuery and an "element" to click on :
$('#element').click(function(){
$(location).attr('href', 'mailto:?subject='
+ encodeURIComponent("This is my subject")
+ "&body="
+ encodeURIComponent("This is my body")
);
});
Then, you can get your contents either by feeding it from input fields (ie. using $('#input1').val()
or by a server side script with $.get('...')

* @param parentIdKey item's key that points to parent (e.g., item.parentId)
* @param noParentValue item's parent value when root (e.g., item.parentId === noParentValue => item is root)
* @param bidirectional should parent reference be added
*/
function flatToTree(data, idKey, parentIdKey, noParentValue = null, bidirectional = true) {
const nodes = {}, roots = {}, leaves = {};
// iterate over all data items
for (const i of data) {
// add item as a node and possibly as a leaf
if (nodes[i[idKey]]) { // already seen this item when child was found first
// add all of the item's data and found children
nodes[i[idKey]] = Object.assign(nodes[i[idKey]], i);
} else { // never seen this item
// add to the nodes map
nodes[i[idKey]] = Object.assign({ $children: []}, i);
// assume it's a leaf for now
leaves[i[idKey]] = nodes[i[idKey]];
}
// put the item as a child in parent item and possibly as a root
if (i[parentIdKey] !== noParentValue) { // item has a parent
if (nodes[i[parentIdKey]]) { // parent already exist as a node
// add as a child
(nodes[i[parentIdKey]].$children || []).push( nodes[i[idKey]] );
} else { // parent wasn't seen yet
// add a "dummy" parent to the nodes map and put the item as its child
nodes[i[parentIdKey]] = { $children: [ nodes[i[idKey]] ] };
}
if (bidirectional) {
// link to the parent
nodes[i[idKey]].$parent = nodes[i[parentIdKey]];
}
// item is definitely not a leaf
delete leaves[i[parentIdKey]];
} else { // this is a root item
roots[i[idKey]] = nodes[i[idKey]];
}
}
return {roots, nodes, leaves};
}
Usage example:
const data = [{id: 2, parentId: 0}, {id: 1, parentId: 2} /*, ... */];
const { nodes, roots, leaves } = flatToTree(data, 'id', 'parentId', 0);
So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]
Use
[A-Z]?
to make the letter optional. {1}
is redundant. (Of course you could also write [A-Z]{0,1}
which would mean the same, but that's what the ?
is there for.)
You could improve your regex to
^([0-9]{5})+\s+([A-Z]?)\s+([A-Z])([0-9]{3})([0-9]{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])[0-9]{3}([0-9]{4})([0-9]{2})([0-9]{2})
And, since in most regex dialects, \d
is the same as [0-9]
:
^(\d{5})+\s+([A-Z]?)\s+([A-Z])(\d{3})(\d{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])\d{3}(\d{4})(\d{2})(\d{2})
But: do you really need 11 separate capturing groups? And if so, why don't you capture the fourth-to-last group of digits?
The server (that the POST request is sent to) needs to include the Content-Type header in its response.
Here's a list of typical headers to include, including one custom "X_ACCESS_TOKEN" header:
"X-ACCESS_TOKEN", "Access-Control-Allow-Origin", "Authorization", "Origin", "x-requested-with", "Content-Type", "Content-Range", "Content-Disposition", "Content-Description"
That's what your http server guy needs to configure for the web server that you're sending your requests to.
You may also want to ask your server guy to expose the "Content-Length" header.
He'll recognize this as a Cross-Origin Resource Sharing (CORS) request and should understand the implications of making those server configurations.
For details see:
Jerryf's answer is fine, except for one flaw.
The onload event should be set before the src. Sometimes the src can be loaded instantly and never fire the onload event.
(Like Totty.js pointed out.)
var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");
var image = new Image();
image.onload = function() {
ctx.drawImage(image, 0, 0);
};
image.src = "data:image/ png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";
By adding a few more headers I was able to get the data:
import urllib2,cookielib
site= "http://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/getHistoricalData.jsp?symbol=JPASSOCIAT&fromDate=1-JAN-2012&toDate=1-AUG-2012&datePeriod=unselected&hiddDwnld=true"
hdr = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11',
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
'Accept-Encoding': 'none',
'Accept-Language': 'en-US,en;q=0.8',
'Connection': 'keep-alive'}
req = urllib2.Request(site, headers=hdr)
try:
page = urllib2.urlopen(req)
except urllib2.HTTPError, e:
print e.fp.read()
content = page.read()
print content
Actually, it works with just this one additional header:
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
While sizeof
works for this specific type of string:
char str[] = "content";
int charcount = sizeof str - 1; // -1 to exclude terminating '\0'
It does not work if str
is pointer (sizeof
returns size of pointer, usually 4 or 8) or array with specified length (sizeof
will return the byte count matching specified length, which for char type are same).
Just use strlen()
.
I tried the solutions above, but had no luck. I noticed this line in my project's package.json:
"bin": {
"webpack-dev-server": "bin/webpack-dev-server.js"
},
I looked at bin/webpack-dev-server.js
and found this line:
.describe("port", "The port").default("port", 8080)
I changed the port to 3000. A bit of a brute force approach, but it worked for me.
It is possible to write to an excel file without opening it using the Microsoft.Jet.OLEDB.4.0
and OleDb
. Using OleDb
, it behaves as if you were writing to a table using sql.
Here is the code I used to create and write to an new excel file. No extra references are needed
var connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\SomePath\ExcelWorkBook.xls;Extended Properties=Excel 8.0";
using (var excelConnection = new OleDbConnection(connectionString))
{
// The excel file does not need to exist, opening the connection will create the
// excel file for you
if (excelConnection.State != ConnectionState.Open) { excelConnection.Open(); }
// data is an object so it works with DBNull.Value
object propertyOneValue = "cool!";
object propertyTwoValue = "testing";
var sqlText = "CREATE TABLE YourTableNameHere ([PropertyOne] VARCHAR(100), [PropertyTwo] INT)";
// Executing this command will create the worksheet inside of the workbook
// the table name will be the new worksheet name
using (var command = new OleDbCommand(sqlText, excelConnection)) { command.ExecuteNonQuery(); }
// Add (insert) data to the worksheet
var commandText = $"Insert Into YourTableNameHere ([PropertyOne], [PropertyTwo]) Values (@PropertyOne, @PropertyTwo)";
using (var command = new OleDbCommand(commandText, excelConnection))
{
// We need to allow for nulls just like we would with
// sql, if your data is null a DBNull.Value should be used
// instead of null
command.Parameters.AddWithValue("@PropertyOne", propertyOneValue ?? DBNull.Value);
command.Parameters.AddWithValue("@PropertyTwo", propertyTwoValue ?? DBNull.Value);
command.ExecuteNonQuery();
}
}
binding name="BindingName"
maxReceivedMessageSize="2097152"
maxBufferSize="2097152"
maxBufferPoolSize="2097152"

I had much better luck testing locally using 127.0.0.1 as the domain. I'm not sure why, but I had mixed results with localhost and .localhost, etc.
Your stored procedure is designed to accept a single parameter, Arg1List. You can't pass 4 parameters to a procedure that only accepts one.
To make it work, the code that calls your procedure will need to concatenate your parameters into a single string of no more than 3000 characters and pass it in as a single parameter.
An example of how to implement it:
public bool ValidateSocialSecNumber(string socialSecNumber)
{
//Accepts only 10 digits, no more no less. (Like Mike's answer)
Regex pattern = new Regex(@"(?<!\d)\d{10}(?!\d)");
if(pattern.isMatch(socialSecNumber))
{
//Do something
return true;
}
else
{
return false;
}
}
You could've also done it in another way by e.g. using Match
and then wrapping a try-catch block around the pattern matching. However, if a wrong input is given quite often, it's quite expensive to throw an exception. Thus, I prefer the above way, in simple cases at least.
How does it work if you only are using visible-md at Col4 instead? Do you use the -lg at all? If not this might work.
<div class="container">
<div class="row">
<div class="col-xs-4 col-sm-2 col-md-1" align="center">
Col1
</div>
<div class="col-xs-4 col-sm-2" align="center">
Col2
</div>
<div class="hidden-xs col-sm-6 col-md-5" align="center">
Col3
</div>
<div class="visible-md col-md-3 " align="center">
Col4
</div>
<div class="col-xs-4 col-sm-2 col-md-1" align="center">
Col5
</div>
</div>
</div>
I will try to cover it with examples:
Lock: One example where you would use lock
would be a shared dictionary into which items (that must have unique keys) are added.
The lock would ensure that one thread does not enter the mechanism of code that is checking for item being in dictionary while another thread (that is in the critical section) already has passed this check and is adding the item. If another thread tries to enter a locked code, it will wait (be blocked) until the object is released.
private static readonly Object obj = new Object();
lock (obj) //after object is locked no thread can come in and insert item into dictionary on a different thread right before other thread passed the check...
{
if (!sharedDict.ContainsKey(key))
{
sharedDict.Add(item);
}
}
Semaphore: Let's say you have a pool of connections, then an single thread might reserve one element in the pool by waiting for the semaphore to get a connection. It then uses the connection and when work is done releases the connection by releasing the semaphore.
Code example that I love is one of bouncer given by @Patric - here it goes:
using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;
namespace TheNightclub
{
public class Program
{
public static Semaphore Bouncer { get; set; }
public static void Main(string[] args)
{
// Create the semaphore with 3 slots, where 3 are available.
Bouncer = new Semaphore(3, 3);
// Open the nightclub.
OpenNightclub();
}
public static void OpenNightclub()
{
for (int i = 1; i <= 50; i++)
{
// Let each guest enter on an own thread.
Thread thread = new Thread(new ParameterizedThreadStart(Guest));
thread.Start(i);
}
}
public static void Guest(object args)
{
// Wait to enter the nightclub (a semaphore to be released).
Console.WriteLine("Guest {0} is waiting to entering nightclub.", args);
Bouncer.WaitOne();
// Do some dancing.
Console.WriteLine("Guest {0} is doing some dancing.", args);
Thread.Sleep(500);
// Let one guest out (release one semaphore).
Console.WriteLine("Guest {0} is leaving the nightclub.", args);
Bouncer.Release(1);
}
}
}
Mutex It is pretty much Semaphore(1,1)
and often used globally (application wide otherwise arguably lock
is more appropriate). One would use global Mutex
when deleting node from a globally accessible list (last thing you want another thread to do something while you are deleting the node). When you acquire Mutex
if different thread tries to acquire the same Mutex
it will be put to sleep till SAME thread that acquired the Mutex
releases it.
Good example on creating global mutex is by @deepee
class SingleGlobalInstance : IDisposable
{
public bool hasHandle = false;
Mutex mutex;
private void InitMutex()
{
string appGuid = ((GuidAttribute)Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(GuidAttribute), false).GetValue(0)).Value.ToString();
string mutexId = string.Format("Global\\{{{0}}}", appGuid);
mutex = new Mutex(false, mutexId);
var allowEveryoneRule = new MutexAccessRule(new SecurityIdentifier(WellKnownSidType.WorldSid, null), MutexRights.FullControl, AccessControlType.Allow);
var securitySettings = new MutexSecurity();
securitySettings.AddAccessRule(allowEveryoneRule);
mutex.SetAccessControl(securitySettings);
}
public SingleGlobalInstance(int timeOut)
{
InitMutex();
try
{
if(timeOut < 0)
hasHandle = mutex.WaitOne(Timeout.Infinite, false);
else
hasHandle = mutex.WaitOne(timeOut, false);
if (hasHandle == false)
throw new TimeoutException("Timeout waiting for exclusive access on SingleInstance");
}
catch (AbandonedMutexException)
{
hasHandle = true;
}
}
public void Dispose()
{
if (mutex != null)
{
if (hasHandle)
mutex.ReleaseMutex();
mutex.Dispose();
}
}
}
then use like:
using (new SingleGlobalInstance(1000)) //1000ms timeout on global lock
{
//Only 1 of these runs at a time
GlobalNodeList.Remove(node)
}
Hope this saves you some time.
Below I have created both a static and dynamic approach at columnizing paragraphs. The code is pretty much self-documented.
Below, you will find the following methods for creating columns:
This is a simple 2 column layout. Based on Glennular's 1st answer.
$(document).ready(function () {_x000D_
var columns = 2;_x000D_
var size = $("#data > p").size();_x000D_
var half = size / columns;_x000D_
$(".col50 > p").each(function (index) {_x000D_
if (index >= half) {_x000D_
$(this).appendTo(".col50:eq(1)");_x000D_
}_x000D_
});_x000D_
});
_x000D_
.col50 {_x000D_
display: inline-block;_x000D_
vertical-align: top;_x000D_
width: 48.2%;_x000D_
margin: 0;_x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

With this approach, I essentially detect if the block needs to be converted to columns. The format is col-{n}
. n
is the number of columns you want to create.

return className.indexOf(prefix) === 0;_x000D_
}).reduce(function(result, value) {_x000D_
return Math.max(parseInt(value.replace(prefix, '')), result);_x000D_
}, 0);_x000D_
var paragraphs = me.find('p').get();_x000D_
me.empty(); // We now have a copy of the children, we can clear the element._x000D_
var size = paragraphs.length;_x000D_
var percent = 1 / count;_x000D_
var width = (percent * 100 - (gap / count || percent)).toFixed(2) + '%';_x000D_
var limit = Math.round(size / count);_x000D_

var gutter = gap / 2 + 'px';_x000D_
for (var col = 0; col < count; col++) {_x000D_
var colDiv = $('<div>').addClass('col').css({ width: width });_x000D_
var css = {};_x000D_

Please take a look at Zdenek Kalal's Predator tracker. It requires some training, but it can actively learn how the tracked object looks at different orientations and scales and does it in realtime!
The source code is available on his site. It's in MATLAB, but perhaps there is a Java implementation already done by a community member. I have succesfully re-implemented the tracker part of TLD in C#. If I remember correctly, TLD is using Ferns as the keypoint detector. I use either SURF or SIFT instead (already suggested by @stacker) to reacquire the object if it was lost by the tracker. The tracker's feedback makes it easy to build with time a dynamic list of sift/surf templates that with time enable reacquiring the object with very high precision.
If you're interested in my C# implementation of the tracker, feel free to ask.
There's one more theoretical possibility to do it: professional versions of Windows have built-in POSIX support, so bash could have been compiled for Windows natively.
Pity, but I still haven't found a compiled one myself...
A little bit off topic but useful is the pythonic numpy
approach. Its robust and fast but just does compare pixels and not the objects or data the picture contains (and it requires images of same size and shape):
A very simple and fast approach to do this without openCV and any library for computer vision is to norm the picture arrays by
import numpy as np
picture1 = np.random.rand(100,100)
picture2 = np.random.rand(100,100)
picture1_norm = picture1/np.sqrt(np.sum(picture1**2))
picture2_norm = picture2/np.sqrt(np.sum(picture2**2))
After defining both normed pictures (or matrices) you can just sum over the multiplication of the pictures you like to compare:
1) If you compare similar pictures the sum will return 1:
In[1]: np.sum(picture1_norm**2)
Out[1]: 1.0
2) If they aren't similar, you'll get a value between 0 and 1 (a percentage if you multiply by 100):
In[2]: np.sum(picture2_norm*picture1_norm)
Out[2]: 0.75389941124629822
Please notice that if you have colored pictures you have to do this in all 3 dimensions or just compare a greyscaled version. I often have to compare huge amounts of pictures with arbitrary content and that's a really fast way to do so.
I am trying to compare date which are in string format like '20110930'
benchMark = datetime.datetime.strptime('20110701', "%Y%m%d")
actualDate = datetime.datetime.strptime('20110930', "%Y%m%d")
if actualDate.date() < benchMark.date():
print True
My issue was I was performing the segue in UIApplicationDelegate

You may get ORA-01031: insufficient privileges
instead of ORA-00942: table or view does not exist
when you have at least one privilege on the table, but not the necessary privilege.
Create schemas
SQL> create user schemaA identified by schemaA;
User created.
SQL> create user schemaB identified by schemaB;
User created.
SQL> create user test_user identified by test_user;

Create objects and privileges
It is unusual, but possible, to grant a schema a privilege like DELETE without granting SELECT.
SQL> create table schemaA.table1(a number);
Table created.
SQL> create table schemaB.table2(a number);
Table created.
SQL> grant delete on schemaB.table2 to test_user;

Make sure that if you have nvarchar(50)in DB row you don't trying to insert more than 50characters in it. Stupid mistake but took me 3 hours to figure it out.
Simple version here What is a general function for JavaScript trim?
function trim(str) {
return str.replace(/^\s+|\s+$/g,"");
}
How about something like this...
Dim rs As RecordSet
Set rs = Currentdb.OpenRecordSet("SELECT PictureLocation, ID FROM MyAccessTable;")
Do While Not rs.EOF
Debug.Print rs("PictureLocation") & " - " & rs("ID")
rs.MoveNext
Loop
I will use CXF also you can think of AXIS 2 .
The best way to do it may be using JAX RS Refer this example
Example:
wsimport -p stockquote http://stockquote.xyz/quote?wsdl
This will generate the Java artifacts and compile them by importing the http://stockquote.xyz/quote?wsdl.
I
use a HEREDOC, which eliminates any need to swap quote types and/or escape them:
echo <<<EOL
<script>$('#edit_errors').html('<h3><em><font color="red">Please Correct Errors Before Proceeding</font></em></h3>')</script>
EOL;
You could wrap the not-bold text into a span and give the span the following properties:
.notbold{
font-weight:normal
}?
and
<h1>**This text should be bold**, <span class='notbold'>but this text should not</span></h1>
See: http://jsfiddle.net/MRcpa/1/
Use <span>
when you want to change the style of elements without placing them in a new block-level element in the document.
If the function is printing to System.out, you can capture that output by using the System.setOut method to change System.out to go to a PrintStream provided by you. If you create a PrintStream connected to a ByteArrayOutputStream, then you can capture the output as a String.
// Create a stream to hold the output
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PrintStream ps = new PrintStream(baos);
// IMPORTANT: Save the old System.out!
PrintStream old = System.out;
// Tell Java to use your special stream
System.setOut(ps);
// Print some output: goes to your special stream
System.out.println("Foofoofoo!");
// Put things back
System.out.flush();
System.setOut(old);
// Show what happened
System.out.println("Here: " + baos.toString());
We have used both and we like Bootstrap for its simplicity and the pace at which it's being developed and enhanced. The problem with jQuery UI is that it's moving at a snail's pace. It's taking years to roll out common features like Menubar, Tree control and DataGrid which are in planning/development stage for ever. We waited waited waited and finally given up and used other libraries like ExtJS for our product http://dblite.com.
Bootstrap has come up with quite a comprehensive set of features in a very short period of time and I am sure it will outpace jQuery UI pretty soon.
So I see no point in using something that will eventually be outdated...
An update on @kalu's answer, which uses the latest pandas:
def find_duplicated_columns(df):
dupes = []
columns = df.columns
for i in range(len(columns)):
col1 = df.iloc[:, i]
for j in range(i + 1, len(columns)):
col2 = df.iloc[:, j]
# break early if dtypes aren't the same (helps deal with
# categorical dtypes)
if col1.dtype is not col2.dtype:
break
# otherwise compare values
if col1.equals(col2):
dupes.append(columns[i])
break
return dupes
another way
List<int> list=new List<int>();
IEnumerable<int> enumerable =Enumerable.Range(1, 300);
foreach (var item in enumerable )
{
list.add(item);
}
In the second image it looks like you want the image to fill the box, but the example you created DOES keep the aspect ratio (the pets look normal, not slim or fat).
I have no clue if you photoshopped those images as example or the second one is "how it should be" as well (you said IS, while the first example you said "should")
Anyway, I have to assume:
If "the images are not resized keeping the aspect ration" and you show me an image which DOES keep the aspect ratio of the pixels, I have to assume you are trying to accomplish the aspect ratio of the "cropping" area (the inner of the green) WILE keeping the aspect ratio of the pixels. I.e. you want to fill the cell with the image, by enlarging and cropping the image.
If that's your problem, the code you provided does NOT reflect "your problem", but your starting example.
Given the previous two assumptions, what you need can't be accomplished with actual images if the height of the box is dynamic, but with background images. Either by using "background-size: contain" or these techniques (smart paddings in percents that limit the cropping or max sizes anywhere you want): http://fofwebdesign.co.uk/template/_testing/scale-img/scale-img.htm
The only way this is possible with images is if we FORGET about your second iimage, and the cells have a fixed height, and FORTUNATELY, judging by your sample images, the height stays the same!
So if your container's height doesn't change, and you want to keep your images square, you just have to set the max-height of the images to that known value (minus paddings or borders, depending on the box-sizing property of the cells)
Like this:
<div class="content">
<div class="row">
<div class="cell">
<img src="http://lorempixel.com/output/people-q-c-320-320-2.jpg"/>
</div>
<div class="cell">
<img src="http://lorempixel.com/output/people-q-c-320-320-7.jpg"/>
</div>
</div>
</div>
And the CSS:
.content {
background-color: green;
}
.row {
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-webkit-box-orient: horizontal;
-moz-box-orient: horizontal;
box-orient: horizontal;
flex-direction: row;
-webkit-box-pack: center;
-moz-box-pack: center;
box-pack: center;
justify-content: center;
-webkit-box-align: center;
-moz-box-align: center;
box-align: center;
align-items: center;
}
.cell {
-webkit-box-flex: 1;
-moz-box-flex: 1;
box-flex: 1;
-webkit-flex: 1 1 auto;
flex: 1 1 auto;
padding: 10px;
border: solid 10px red;
text-align: center;
height: 300px;
display: flex;
align-items: center;
box-sizing: content-box;
}
img {
margin: auto;
width: 100%;
max-width: 300px;
max-height:100%
}
Your code is invalid (opening tags are instead of closing ones, so they output NESTED cells, not siblings, he used a SCREENSHOT of your images inside the faulty code, and the flex box is not holding the cells but both examples in a column (you setup "row" but the corrupt code nesting one cell inside the other resulted in a flex inside a flex, finally working as COLUMNS. I have no idea what you wanted to accomplish, and how you came up with that code, but I'm guessing what you want is this.
I added display: flex to the cells too, so the image gets centered (I think display: table
could have been used here as well with all this markup)
You can use php if you write css in the Tag
<style>
section {
position: fixed;
top: <?php if ($test == $tset) { echo '10px' }; ?>;
}
</style
You need to set the inflated view "Clickable" and "able to listen to click events" in your adapter class getView() method.
convertView = mInflater.inflate(R.layout.list_item_text, null);
convertView.setClickable(true);
convertView.setOnClickListener(myClickListener);
and declare the click listener in your ListActivity as follows,
public OnClickListener myClickListener = new OnClickListener() {
public void onClick(View v) {
//code to be written to handle the click event
}
};
This holds true only when you are customizing the Adapter by extending BaseAdapter.

Your XML file was not found. Try using absolute paths like:
/path/to/my/file (Mac, Linux)
C:\\path\\to\\my\\file (Windows)
You can set a default style for the entire workbook (all worksheets):
$objPHPExcel->getDefaultStyle()
->getBorders()
->getTop()
->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
->getBorders()
->getBottom()
->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
->getBorders()
->getLeft()
->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
->getBorders()
->getRight()
->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
or
$styleArray = array(
'borders' => array(
'allborders' => array(
'style' => PHPExcel_Style_Border::BORDER_THIN
)
)
);
$objPHPExcel->getDefaultStyle()->applyFromArray($styleArray);
And this can be used for all style properties, not just borders.
But column autosizing is structural
rather than stylistic
, and has to be set for each column on each worksheet individually.
EDIT
Note that default workbook style only applies to Excel5 Writer
can gridmove be of any assistance?
very handy tool on larger screens...
If this is for MS SQL.. The following code will always run no matter what if the table exist already or not.
if object_id('mytablename') is not null //has the table been created already in the db

drop table mytablename
End
Create table mytablename (...
After wasting an hour on complex and hacky solutions, I've found both simple and valid solution for commenting my bulky dependencies section in package.json
. Just like this:
{
"name": "package name",
"version": "1.0",
"description": "package description",
"scripts": {
"start": "npm install && node server.js"
},
"scriptsComments": {
"start": "Runs development build on a local server configured by server.js"
},
"dependencies": {
"ajv": "^5.2.2"
},
"dependenciesComments": {
"ajv": "JSON-Schema Validator for validation of API data"
}
}
When sorted the same way, it's now very easy for me to track these pairs of dependencies/comments either in Git commit diffs or in an editor while working with file package.json
.
And no extra tools are involved, just plain and valid JSON.
Yes it can be eliminated with the /Yc options like others have pointed out but most likely you wouldn't need to touch it to fix it. Why are you getting this error in the first place without changing any settings? You might have 'cleaned' the project and than try to compile a single cpp file. You would get this error in that case because the precompiler header is now missing. Just build the whole project (even if unsuccessful) and than build any single cpp file and you won't get this error.
I don't know if this what you want but try to remove overflow: hidden from #wrap
As stated in the other answers:
MOV
will grab the data at the address inside the brackets and place that data into the destination operand.LEA
will perform the calculation of the address inside the brackets and place that calculated address into the destination operand. This happens without actually going out to the memory and getting the data. The work done by LEA
is in the calculating of the "effective address".Because memory can be addressed in several different ways (see examples below), LEA
is sometimes used to add or multiply registers together without using an explicit ADD
or MUL
instruction (or equivalent).
Since everyone is showing examples in Intel syntax, here are some in AT&T syntax:
MOVL 16(%ebp), %eax /* put long at ebp+16 into eax */
LEAL 16(%ebp), %eax /* add 16 to ebp and store in eax */
MOVQ (%rdx,%rcx,8), %rax /* put qword at rcx*8 + rdx into rax */
LEAQ (%rdx,%rcx,8), %rax /* put value of "rcx*8 + rdx" into rax */
MOVW 5(%bp,%si), %ax /* put word at si + bp + 5 into ax */
LEAW 5(%bp,%si), %ax /* put value of "si + bp + 5" into ax */
MOVQ 16(%rip), %rax /* put qword at rip + 16 into rax */
LEAQ 16(%rip), %rax /* add 16 to instruction pointer and store in rax */
MOVL label(,1), %eax /* put long at label into eax */
LEAL label(,1), %eax /* put the address of the label into eax */
I saw this problem today when trying to create a WCF service proxy, both using VS2010 and svcutil.
Everything I'm doing is with basicHttpBinding
(so no issue with wsHttpBinding
).
For the first time in my recollection MSDN actually provided me with the solution, at the following link How to: Publish Metadata for a Service Using a Configuration File. The line I needed to change was inside the behavior element inside the MEX service behavior element inside my service app.config file. I changed it from
<serviceMetadata httpGetEnabled="true"/>
to
<serviceMetadata httpGetEnabled="true" policyVersion="Policy15"/>
and like magic the error went away and I was able to create the service proxy. Note that there is a corresponding MSDN entry for using code instead of a config file: How to: Publish Metadata for a Service Using Code.
(Of course, Policy15 - how could I possibly have overlooked that???)
One more "gotcha": my service needs to expose 3 different endpoints, each supporting a different contract. For each proxy that I needed to build, I had to comment out the other 2 endpoints, otherwise svcutil would complain that it could not resolve the base URL address.
i supposed you uploaded your photo in your drive all what you need to do is while you are opening your google drive just open your dev tools in chrome and head to your img tag and copy the link beside the src attribute and use it
delete acts like a non real world situation, it just removes the item, but the array length stays the same:
example from node terminal:
> var arr = ["a","b","c","d"];
> delete arr[2]
true
> arr
[ 'a', 'b', , 'd', 'e' ]
Here is a function to remove an item of an array by index, using slice(), it takes the arr as the first arg, and the index of the member you want to delete as the second argument. As you can see, it actually deletes the member of the array, and will reduce the array length by 1
function(arr,arrIndex){
return arr.slice(0,arrIndex).concat(arr.slice(arrIndex + 1));
}
What the function above does is take all the members up to the index, and all the members after the index , and concatenates them together, and returns the result.
Here is an example using the function above as a node module, seeing the terminal will be useful:
> var arr = ["a","b","c","d"]
> arr
[ 'a', 'b', 'c', 'd' ]
> arr.length
4
> var arrayRemoveIndex = require("./lib/array_remove_index");
> var newArray = arrayRemoveIndex(arr,arr.indexOf('c'))
> newArray
[ 'a', 'b', 'd' ] // c ya later
> newArray.length
3
please note that this will not work one array with dupes in it, because indexOf("c") will just get the first occurance, and only splice out and remove the first "c" it finds.
You would use the read.csv
function; for example:
dat = read.csv("spam.csv", header = TRUE)
You can also reference this tutorial for more details.
Note: make sure the .csv
file to read is in your working directory (using getwd()
) or specify the right path to file. If you want, you can set the current directory using setwd
.
For those who understand the bias problem but can't stand the unpredictable run-time of rejection-based methods, this series produces a progressively less biased random integer in the [0, n-1]
interval:
r = n / 2;
r = (rand() * n + r) / (RAND_MAX + 1);
r = (rand() * n + r) / (RAND_MAX + 1);
r = (rand() * n + r) / (RAND_MAX + 1);
...
It does so by synthesising a high-precision fixed-point random number of i * log_2(RAND_MAX + 1)
bits (where i
is the number of iterations) and performing a long multiplication by n
.
When the number of bits is sufficiently large compared to n
, the bias becomes immeasurably small.
It does not matter if RAND_MAX + 1
is less than n
(as in this question), or if it is not a power of two, but care must be taken to avoid integer overflow if RAND_MAX * n
is large.
Best way is running Particular migration again by using down or up(in rails 4. It's change)
rails db:migrate:up VERSION=timestamp
Now how you get the timestamp. Go to this path
/db/migrate
Identify migration file you want to revert.pick the timestamp from that file name.
If you want downloads number for each customer, use:
select ssn
, sum(time)
from downloads
group by ssn
If you want just one record -- for a customer with highest number of downloads -- use:
select *
from (
select ssn
, sum(time)
from downloads
group by ssn
order by sum(time) desc
)
where rownum = 1
However if you want to see all customers with the same number of downloads, which share the highest position, use:
select *
from (
select ssn
, sum(time)
, dense_rank() over (order by sum(time) desc) r
from downloads
group by ssn
)
where r = 1
Just Override the boolean equals() method of custom object. Say you have an ArrayList with custom field f1, f2, ... override
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (!(o instanceof CustomObject)) return false;
CustomObject object = (CustomObject) o;
if (!f1.equals(object.dob)) return false;
if (!f2.equals(object.fullName)) return false;
...
return true;
}
and check using ArrayList instance's contains() method. That's it.
Try this:
// convert from bitmap to byte array
public byte[] getBytesFromBitmap(Bitmap bitmap) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 70, stream);
return stream.toByteArray();
}
// get the base 64 string
String imgString = Base64.encodeToString(getBytesFromBitmap(someImg),
Base64.NO_WRAP);
PHP doesn't support traditional method overloading, however one way you might be able to achieve what you want, would be to make use of the __call
magic method:
class MyClass {
public function __call($name, $args) {
switch ($name) {
case 'funcOne':
switch (count($args)) {
case 1:
return call_user_func_array(array($this, 'funcOneWithOneArg'), $args);
case 3:
return call_user_func_array(array($this, 'funcOneWithThreeArgs'), $args);
}
case 'anotherFunc':
switch (count($args)) {
case 0:
return $this->anotherFuncWithNoArgs();
case 5:
return call_user_func_array(array($this, 'anotherFuncWithMoreArgs'), $args);
}
}
}
protected function funcOneWithOneArg($a) {
}
protected function funcOneWithThreeArgs($a, $b, $c) {
}
protected function anotherFuncWithNoArgs() {
}
protected function anotherFuncWithMoreArgs($a, $b, $c, $d, $e) {
}
}
With an Android-powered device, you can develop and debug your Android applications just as you would on the emulator.
1. Declare your application as "debuggable" in AndroidManifest.xml
.
<application
android:debuggable="true"
... >
...
</application>
2. On your handset, navigate to Settings > Security and check Unknown sources
3. Go to Settings > Developer Options and check USB debugging
Note that if Developer Options
is invisible you will need to navigate to Settings > About Phone and tap on Build number
several times until you are notified that it has been unlocked.
4. Set up your system to detect your device.
Follow the instructions below for your OS:
Install the Google USB Driver from the ADT SDK Manager
(Support for: ADP1, ADP2, Verizon Droid, Nexus One, Nexus S).
For devices not listed above, install an OEM driver for your device
Your device should automatically work; Go to the next step
Add a udev
rules file that contains a USB configuration for each type of device you want to use for development. In the rules file, each device manufacturer is identified by a unique vendor ID, as specified by the ATTR{idVendor} property. For a list of vendor IDs, click here. To set up device detection on Ubuntu Linux:
/etc/udev/rules.d/51-android.rules
.SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"
chmod a+r /etc/udev/rules.d/51-android.rules
Note: The rule syntax may vary slightly depending on your environment. Consult the udev documentation for your system as needed. For an overview of rule syntax, see this guide to writing udev rules.
5. Run the project with your connected device.
With Eclipse/ADT: run or debug your application as usual. You will be presented with a Device Chooser dialog that lists the available emulator(s) and connected device(s).
With ADB: issue commands with the -d flag to target your connected device.

I found a way if you're going across classes and want the class the method belongs to AND the method. It takes a bit of extraction work but it makes its point. This works in Python 2.7.13.
import inspect, os
class ClassOne:
def method1(self):
classtwoObj.method2()
class ClassTwo:
def method2(self):
curframe = inspect.currentframe()
calframe = inspect.getouterframes(curframe, 4)
print '\nI was called from', calframe[1][3], \
'in', calframe[1][4][0][6: -2]
# create objects to access class methods
classoneObj = ClassOne()
classtwoObj = ClassTwo()
# start the program
os.system('cls')
classoneObj.method1()
Inspired from this post and that post, I use this code to generate and verify hashed salted passwords. It only uses JDK provided classes, no external dependency.

method to generate a salted and hashed password. The method returns a byte[]
which you can save as is in a database with the saltisExpectedPassword
method to check that the details match/**

You would have to configure your webserver to utilize PHP as handler for .html
files. This is typically done by modifying your with AddHandler
to include .html
along with .php
.
Note that this could have a performance impact as this would cause ALL .html files to be run through PHP handler even if there is no PHP involved. So you might strongly consider using .php
extension on these files and adding a redirect as necessary to route requests to specific .html URL's to their .php equivalents.
Yet another reason happened in my case, because of using async
/await
, resulting in the same error message:
System.InvalidOperationException: 'Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.'
Just a quick overview of what happened (and how I resolved it), hopefully this will help others in the future:
This all happened in an ASP.NET Core 3.1 web project with Dapper and SQL Server, but I do think it is independent of that very kind of project.
First, I have a central function to get me SQL connections:
internal async Task<DbConnection> GetConnection()
{
var r = new SqlConnection(GetConnectionString());
await r.OpenAsync().ConfigureAwait(false);
return r;
}
I'm using this function in dozens of methods like e.g. this one:
public async Task<List<EmployeeDbModel>> GetAll()
{
await using var conn = await GetConnection();
var sql = @"SELECT * FROM Employee";
var result = await conn.QueryAsync<EmployeeDbModel>(sql);
return result.ToList();
}
As you can see, I'm using the new using
statement without the curly braces ({
, }
), so disposal of the connection is done at the end of the function.
Still, I got the error about no more connections in the pool being available.
I started debugging my application and let it halt upon the exception happening. When it halted, I first did a look at the Call Stack window, but this only showed some location inside System.Data.SqlClient, and was no real help to me:
Next, I took a look at the Tasks window, which was of a much better help:
There were literally thousands of calls to my own GetConnection
method in an "Awaiting" or "Scheduled" state.
When double-clicking such a line in the Tasks window, it showed me the related location in my code via the Call Stack window.
This helped my to find out the real reason of this behaviour. It was in the below code (just for completeness):
[Route(nameof(LoadEmployees))]
public async Task<IActionResult> LoadEmployees(
DataSourceLoadOptions loadOption)
{
var data = await CentralDbRepository.EmployeeRepository.GetAll();
var list =
data.Select(async d =>
{
var values = await CentralDbRepository.EmployeeRepository.GetAllValuesForEmployee(d);
return await d.ConvertToListItemViewModel(
values,
Config,
CentralDbRepository);
})
.ToListAsync();
return Json(DataSourceLoader.Load(await list, loadOption));
}
In the above controller action, I first did a call to EmployeeRepository.GetAll()
to get a list of models from the database table "Employee".
Then, for each of the returned models (i.e. for each row of the result set), I did again do a database call to EmployeeRepository.GetAllValuesForEmployee(d)
.
While this is very bad in terms of performance anyway, in an async context it behaves in a way, that it is eating up connection pool connections without releasing them appropriately.
I resolved it by removing the SQL query in the inner loop of the outer SQL query.
This should be done by either completely omitting it, or if required, move it to one/multilpe JOIN
s in the outer SQL query to get all data from the database in one single SQL query.
Don't do lots of SQL queries in a short amount of time, especially when using async
/await
.
It is working for me. I think you probably need to use urlencode()
on each of the components of $map_url
.
There is no difference. From RDD.scala
.
/** Persist this RDD with the default storage level (`MEMORY_ONLY`). */
def persist(): this.type = persist(StorageLevel.MEMORY_ONLY)
/** Persist this RDD with the default storage level (`MEMORY_ONLY`). */
def cache(): this.type = persist()
I would suggest 3 things:
The last one worked for me.
There's a fantastic jQuery tutorial for this at https://web.archive.org/web/20121012171851/http://jqueryfordesigners.com/fixed-floating-elements/.
It replicates the Apple.com shopping cart type of sidebar scrolling. The Google query that might have served you well is "fixed floating sidebar".
You need to add the command 'go' after you set the identity insert. Example:
SET IDENTITY_INSERT sometableWithIdentity ON
go
INSERT sometableWithIdentity (IdentityColumn, col2, col3, ...)
VALUES (AnIdentityValue, col2value, col3value, ...)
SET IDENTITY_INSERT sometableWithIdentity OFF
go
If you want to get values in Javascript on frontend, you can use the native way to do it by using :
document.getElementsByName("movie")[0].value;
Where "movie"
is the name of your input
<input type="text" name="movie">
If you want to get it on angular.js controller, you can use;
$scope.movie
Elaborating on previous answer by Pir Fahim, he's right but i'm using selectedItem.Text (only way to make it work to me)
Use the SelectedIndexChanged() event to store the data somewhere. In my case, i usually fill a custom class, something like:
class myItem {
string name {get; set;}
string price {get; set;}
string desc {get; set;}
}
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
myItem selected_item = new myItem();
selected_item.name = listBox1.SelectedItem.Text;
Retrieve (selected_item.name);
}
And then you can retrieve the rest of data from a List of "myItems"..
myItem Retrieve (string wanted_item) {
foreach (myItem item in my_items_list) {
if (item.name == wanted_item) {
// This is the selected item
return item;
}
}
return null;
}
you can use
SELECT timestamp, value, card
FROM my_table
ORDER BY timestamp DESC
LIMIT 1
assuming you want also to sort by timestamp
?
Another thing that might not have been mentioned already is that urllib.urlencode()
will encode empty values in the dictionary as the string None
instead of having that parameter as absent. I don't know if this is typically desired or not, but does not fit my use case, hence I have to use quote_plus
.
You can do it with an confirm()
message using Javascript.
For me this was a lot of searching. Eventually I decided to use NuGet instead of downloading the files myself. I deleted all involved scripts and scriptbundles and got the following packages (latest versions as of now)
Then I added these bundles to the BundleConfig file:
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));
bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
"~/Scripts/jquery.validate.js",
"~/Scripts/jquery.validate.unobtrusive.js",
"~/Scripts/jquery.unobtrusive-ajax.js"));
I added this reference to _Layout.cshtml:
@Scripts.Render("~/bundles/jquery")
And I added this reference to whichever view I needed validation:
@Scripts.Render("~/bundles/jqueryval")
Now everything worked.
Don't forget these things (many people forget them):
I wanted the Number same as I get from database for example.
1) 00100.220000
2) 00123
3) 0000.0000100
So I modified the code as below
$objPHPExcel->getActiveSheet()
->setCellValue('A3', '00100.220000');
$objPHPExcel->getActiveSheet()
->getStyle('A3')
->getNumberFormat()
->setFormatCode('00000.000000');
$objPHPExcel->getActiveSheet()
->setCellValue('A4', '00123');
$objPHPExcel->getActiveSheet()
->getStyle('A4')
->getNumberFormat()
->setFormatCode('00000');
$objPHPExcel->getActiveSheet()
->setCellValue('A5', '0000.0000100');
$objPHPExcel->getActiveSheet()
->getStyle('A5')
->getNumberFormat()
->setFormatCode('0000.0000000');

In embed.js:
var me = document.querySelector('script[src="//example.com/embed.js"]');
defer
& async
)id
attributeWe can also loop over every script element and check each individually to select the one we want:
<script>
var me = null;
var scripts = document.getElementsByTagName("script")
for (var i = 0; i < scripts.length; ++i) {
if( isMe(scripts[i])){
me = scripts[i];
}
}
</script>
This lets us use both previous techniques in older browsers that don't support querySelector()
well with attributes. For example:
function isMe(scriptElem){
return scriptElem.getAttribute('src') === "//example.com/embed.js";
}
This inherits the benefits and problems of whatever approach is taken, but does not rely on querySelector()
so will work in older browsers.
Since the scripts are executed sequentially, the last script element will very often be the currently running script:
<script>
var scripts = document.getElementsByTagName( 'script' );
var me = scripts[ scripts.length - 1 ];
</script>

)Include comments if you choose; strip them out with a minifier before parsing or transmitting.
I just released JSON.minify() which strips out comments and whitespace from a block of JSON and makes it valid JSON that can be parsed. So, you might use it like:
JSON.parse(JSON.minify(my_str));
When I released it, I got a huge backlash of people disagreeing with even the idea of it, so I decided that I'd write a comprehensive blog post on why comments make sense in JSON. It includes this notable comment from the creator of JSON:
Suppose you are using JSON to keep configuration files, which you would like to annotate. Go ahead and insert all the comments you like. Then pipe it through JSMin before handing it to your JSON parser. - Douglas Crockford, 2012
Hopefully that's helpful to those who disagree with why JSON.minify() could be useful.

I wouldn't risk it because you might end up losing data that should have been preserved. hbm2ddl.auto=update is purely an easy way to keep your dev database up to date.
There is a better why to determine type of an image. with exif_imagetype
If you use this function, you can tell image's real extension.
with this function filename's extension is completely irrelevant, which is good.
function setHeaderContentType(string $filePath): void
{
$numberToContentTypeMap = [
'1' => 'image/gif',
'2' => 'image/jpeg',
'3' => 'image/png',
'6' => 'image/bmp',
'17' => 'image/ico'
];
$contentType = $numberToContentTypeMap[exif_imagetype($filePath)] ?? null;
if ($contentType === null) {
throw new Exception('Unable to determine content type of file.');
}
header("Content-type: $contentType");
}
You can add more types from the link.
Hope it helps.

If anyone else came here like me trying to find a solution for the error:
'env' is not recognized as an internal or external command
The reason I got this is that I was migrating an angular solution from a mac development machine over to a windows 10 desktop. This is how I resolved it.
run npm install --save-dev cross-env
go into my package.json file and change all the script references from env <whatever>
to cross-env <whatever>
Then my commands like: npm run start:some_random_environment_var
now run fine on Windows 10.
@AnsgarWiechers - it's not my experience that querying everything and then pruning the result is more efficient when you're doing a targeted search of known accounts. Although, yes, it is also more efficient to select just the properties you need to return.
The below examples are based on a domain in the range of 20,000 account objects.
measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st }
...
Seconds : 16
Milliseconds : 208
measure-command {$userlist | get-aduser -Properties DisplayName,st}
...
Seconds : 3
Milliseconds : 496
In the second example, $userlist contains 368 account names (just strings, not pre-fetched account objects).
Note that if I include the where
clause per your suggestion to prune to the actually desired results, it's even more expensive.
measure-command {Get-ADUser -Filter '*' -Properties DisplayName,st |where {$userlist -Contains $_.samaccountname } }
...
Seconds : 17
Milliseconds : 876
Indexed attributes seem to have similar performance (I tried just returning displayName
).
Even if I return all user account properties in my set, it's more efficient. (Adding a select statement to the below brings it down by a half-second).
measure-command {$userlist | get-aduser -Properties *}
...
Seconds : 12
Milliseconds : 75
I can't find a good document that was written in ye olde days about AD queries to link to, but you're hitting every account in your search scope to return the properties. This discusses the basics of doing effective AD queries - scoping and filtering: https://msdn.microsoft.com/en-us/library/ms808539.aspx#efficientadapps_topic01
When your search scope is "*", you're still building a (big) list of the objects and iterating through each one. An LDAP search filter is always more efficient to build the list first (or a narrow search base, which is again building a smaller list to query).
I may be wrong, but I believe I've seen a list of previous SQL queries in the session file for phpmyadmin sessions

Since set_value
has been deprecated since version 0.21.0, you should now use at

can refer to values as well as rows and columns.

1 2 [m, n]

You also need to make sure the column you are inserting into has dtype=object
. For example
>>> df = pd.DataFrame(data={'A': [1, 2, 3], 'B': [1,2,3]})
>>> df.dtypes
A int64
B int64
dtype: object
>>> df.at[1, 'B'] = [1, 2, 3]

VirtualBox is a virtualizer, not an emulator. (The name kinda gives it away.) I.e. it can only virtualize a CPU that is actually there, not emulate one that isn't. In particular, VirtualBox can only virtualize x86 and AMD64 CPUs. iOS only runs on ARM CPUs.

because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").
In fact, Python only allows you to use the in

Tthe problems may be caused by incorrect mapping. Are you sure you have your result set in "data"? In my example, the backend code returns results under "items" key, so the mapping should look like:
results: $.map(data.items, function (item) {
....
}
and not:
results: $.map(data, function (item) {
....
}

The answer is not simple:
It depends on the target machines (mobile vs desktop), it depends on the nature of your data, the browser, the OS, the hardware it runs on... you will need to benchmark if you really want to know.
It is mostly a memory vs computation problem ... as with most performance issues the difference can become significant with repeated elements (n) like lists, especially when nested (n x n, or worse) and also what kind of computations you run inside these elements:
ng-show: If those optional elements are often present (dense), like say 90% of the time, it may be faster to have them ready and only show/hide them, especially if their content is cheap (just plain text, nothing to compute or load). This consumes memory as it fills the DOM with hidden elements, but just show/hide something which already exists is likely to be a cheap operation for the browser.
ng-if: If on the contrary elements are likely not to be shown (sparse) just build them and destroy them in real time, especially if their content is expensive to get (computations/sorted/filtered, images, generated images). This is ideal for rare or 'on-demand' elements, it saves memory in terms of not filling the DOM but can cost a lot of computation (creating/destroying elements) and bandwidth (getting remote content). It also depends on how much you compute in the view (filtering/sorting) vs what you already have in the model (pre-sorted/pre-filtered data).
The browser is not adding any padding. Instead, letters (even uppercase letters) are generally considerably smaller in the vertical direction than the height of the font, not to mention the line height, which is typically by default about 1.2 times the font height (font size).
There is no general solution to this because fonts are different. Even for fixed font size, the height of a letter varies by font. And uppercase letters need not have the same height in a font.
Practical solutions can be found by experimentation, but they are unavoidably font-dependent. You will need to set the line height essentially smaller than the font size. The following seems to yield the desired result in different browsers on Windows, for the Arial font:
span.foo_x000D_
{_x000D_
display: inline-block;_x000D_
font-size: 50px;_x000D_
background-color: green;_x000D_
line-height: 0.75em;_x000D_
font-family: Arial;_x000D_
}_x000D_
_x000D_
span.bar_x000D_
{_x000D_
position: relative;_x000D_
bottom: -0.02em;_x000D_
}
_x000D_
<span class=foo><span class=bar>BIG TEXT</span></span>
_x000D_
The nested span
elements are used to displace the text vertically. Otherwise, the text sits on the baseline, and under the baseline, there is room reserved for descenders (as in letters j and y).
If you look closely (with zooming), you will notice that there is very small space above and below most letters here. I have set things so that the letter “G” fits in. It extends vertically a bit farther than other uppercase letters because that way the letters look similar in height. There are similar issues with other letters, like “O”. And you need to tune the settings if you’ll need the letter “Q” since it has a descender that extends a bit below the baseline (in Arial). And of course, if you’ll ever need “É”, or almost any diacritic mark, you’re in trouble.
That syntax works fine for me:
CREATE FUNCTION dbo.test_func

Do I need to pass pointers, references, or non-pointer and non-reference values?
This is a question that matters when writing a function and choosing the types of the parameters it takes. That choice will affect how the function is called and it depends on a few things.
The simplest option is to pass objects by value. This basically creates a copy of the object in the function, which has many advantages. But sometimes copying is costly, in which case a constant reference, const&
, is usually best. And sometimes you need your object to be changed by the function. Then a non-constant reference, &
, is needed.
For guidance on the choice of parameter types, see the Functions section of the C++ Core Guidelines, starting with F.15. As a general rule, try to avoid raw pointers, *
.
For me the error occurred due to my browser using a cached version of the js file containing the module. Clearing the cache and reloading the page solved the problem.
It would be best to have a TIMESTAMP
column that defaults to CURRENT_TIMESTAMP
.. it is the only true predictive behavior you can find here.
The second-best thing you can do is ORDER BY ID DESC LIMIT 1
and hope the newest ID is the largest value.
I used the following property which works fine for me:
$('#selector').dialog({
minHeight: 'auto'
});

As well as making sure that you have first called $("#myForm").validate();
, make sure that your dynamic control has been added to the DOM before adding the validation rules.

Note that you need Tomcat 7.0.41 or higher.
To know where the current instance of Tomcat is located try this:
System.out.println(System.getProperty("catalina.base"));
You'll see the path in the console view.
Then look for /conf/web.xml on that folder, open it and add the lines of the above link.

I only observed this error today, for me the Error code was different though.
SCRIPT7002: XMLHttpRequest: Network Error 0x2efd, Could not complete the operation due to error 00002efd.
It was occurring randomly and not all the time. but what it noticed is, if it comes for subsequent ajax calls. so i put some delay of 5 seconds between the ajax calls and it resolved.
You should create new SSH key set for that Docker image, as you probably don't want to embed there your own private key. To make it work, you'll have to add that key to deployment keys in your git repository. Here's complete recipe:
Generate ssh keys with ssh-keygen -q -t rsa -N '' -f repo-key
which will give you repo-key and repo-key.pub files.
Add repo-key.pub to your repository deployment keys.
On GitHub, go to [your repository] -> Settings -> Deploy keys
Add something like this to your Dockerfile:
ADD repo-key / RUN \ chmod 600 /repo-key && \ echo "IdentityFile /repo-key" >> /etc/ssh/ssh_config && \ echo -e "StrictHostKeyChecking no" >> /etc/ssh/ssh_config && \ // your git clone commands here...
Note that above switches off StrictHostKeyChecking, so you don't need .ssh/known_hosts. Although I probably like more the solution with ssh-keyscan in one of the answers above.
I ended up going with the following solution:
public class HttpActionResult : IHttpActionResult
{
private readonly string _message;
private readonly HttpStatusCode _statusCode;
public HttpActionResult(HttpStatusCode statusCode, string message)
{
_statusCode = statusCode;
_message = message;
}
public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
{
HttpResponseMessage response = new HttpResponseMessage(_statusCode)
{
Content = new StringContent(_message)
};
return Task.FromResult(response);
}
}
... which can be used like this:
public IHttpActionResult Get()
{
return new HttpActionResult(HttpStatusCode.InternalServerError, "error message"); // can use any HTTP status code
}
I'm open to suggestions for improvement. :)
"\n" = new line
'\n' = \n
"\t" = tab

I also struggled a lot with this issue. The answers in this thread were helpful but were not enough to resolve my error. You will need to disable Hyper-V and Device guard like the other answers have suggested. More info on that can be found in here.
I am including the changes needed to be done in addition to the answers provided above. The link that finally helped me was this.
My answer is going to summarize only the difference between the rest of the answers (i.e. Disabling Hyper-V and Device guard) and the following steps :
Delete the following registry settings:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA\LsaCfgFlags HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\DeviceGuard\EnableVirtualizationBasedSecurity HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\DeviceGuard\RequirePlatformSecurityFeatures
Important : If you manually remove these registry settings, make sure to delete them all. If you don't remove them all, the device might go into BitLocker recovery.
Delete the Windows Defender Credential Guard EFI variables by using bcdedit. From an elevated command prompt(start in admin mode), type the following commands:
mountvol X: /s
copy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Y
bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloader
bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"
bcdedit /set {bootmgr} bootsequence {0cb3b571-2f2e-4343-a879-d86a476d7215}
bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO
bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:
mountvol X: /d
Restart the PC.
Accept the prompt to disable Windows Defender Credential Guard.
Alternatively, you can disable the virtualization-based security features to turn off Windows Defender Credential Guard.
Hopefully this is self explanatory enough. Use the comments in the code to help understand what is happening. Pass a single cell to this function. The value of that cell will be the base file name. If the cell contains "AwesomeData" then we will try and create a file in the current users desktop called AwesomeData.pdf. If that already exists then try AwesomeData2.pdf and so on. In your code you could just replace the lines filename = Application.....
with filename = GetFileName(Range("A1"))
Function GetFileName(rngNamedCell As Range) As String
Dim strSaveDirectory As String: strSaveDirectory = ""
Dim strFileName As String: strFileName = ""
Dim strTestPath As String: strTestPath = ""
Dim strFileBaseName As String: strFileBaseName = ""
Dim strFilePath As String: strFilePath = ""
Dim intFileCounterIndex As Integer: intFileCounterIndex = 1
' Get the users desktop directory.
strSaveDirectory = Environ("USERPROFILE") & "\Desktop\"
Debug.Print "Saving to: " & strSaveDirectory
' Base file name
strFileBaseName = Trim(rngNamedCell.Value)
Debug.Print "File Name will contain: " & strFileBaseName
' Loop until we find a free file number
Do
If intFileCounterIndex > 1 Then
' Build test path base on current counter exists.
strTestPath = strSaveDirectory & strFileBaseName & Trim(Str(intFileCounterIndex)) & ".pdf"
Else
' Build test path base just on base name to see if it exists.
strTestPath = strSaveDirectory & strFileBaseName & ".pdf"
End If
If (Dir(strTestPath) = "") Then
' This file path does not currently exist. Use that.
strFileName = strTestPath
Else
' Increase the counter as we have not found a free file yet.
intFileCounterIndex = intFileCounterIndex + 1
End If
Loop Until strFileName <> ""
' Found useable filename
Debug.Print "Free file name: " & strFileName
GetFileName = strFileName
End Function
The debug lines will help you figure out what is happening if you need to step through the code. Remove them as you see fit. I went a little crazy with the variables but it was to make this as clear as possible.
In Action
My cell O1 contained the string "FileName" without the quotes. Used this sub to call my function and it saved a file.
Sub Testing()
Dim filename As String: filename = GetFileName(Range("o1"))
ActiveWorkbook.Worksheets("Sheet1").Range("A1:N24").ExportAsFixedFormat Type:=xlTypePDF, _

Where is your code located in reference to everything else? Perhaps you need to make a module if you have not already and move your existing code into there.
find ./ -type f -name "*.php" -o -name "*.html" -printf '%P\n' |xargs tar -I 'pigz -9' -cf target.tgz
for multicore or just for one core:
find ./ -type f -name "*.php" -o -name "*.html" -printf '%P\n' |xargs tar -czf target.tgz
$CurrentFolder = "H:\Documents"
$Query = "Select * from Win32_NetworkConnection where LocalName = '" + $CurrentFolder.Substring( 0, 2 ) + "'"
( Get-WmiObject -Query $Query ).RemoteName
OR
$CurrentFolder = "H:\Documents"
$Tst = $CurrentFolder.Substring( 0, 2 )
( Get-WmiObject -Query "Select * from Win32_NetworkConnection where LocalName = '$Tst'" ).RemoteName
the first command is correct but change from convert to export to csv, as below,
Get-ADUser -Filter * -Properties * `
| Select-Object -Property Name,SamAccountName,Description,EmailAddress,LastLogonDate,Manager,Title,Department,whenCreated,Enabled,Organization `
| Sort-Object -Property Name `
| Export-Csv -path C:\Users\*\Desktop\file1.csv
Sorting all the records first, do consume a lot of time (Imagine if the table contains millions of records). However, the trick is to do an improved linear-search.
SELECT * FROM Employee Emp1
WHERE (N-1) = ( SELECT COUNT(*) FROM (
SELECT DISTINCT(Emp2.Salary)
FROM Employee Emp2
WHERE Emp2.Salary > Emp1.Salary LIMIT N))
Here, as soon as inner query finds n distinct salary values greater than outer query's salary, it returns the result to outer query.
Mysql have clearly mentioned about this optimization at http://dev.mysql.com/doc/refman/5.6/en/limit-optimization.html
The above query can also be written as,
SELECT * FROM Employee Emp1
WHERE (N-1) = (
SELECT COUNT(DISTINCT(Emp2.Salary))
FROM Employee Emp2
WHERE Emp2.Salary > Emp1.Salary LIMIT N)
Again, if the queries are as simple as just running on single table and needed for informational purposes only, then you could limit the outermost query to return 1 record and run a separate query by placing the nth highest salary in where clause
Thanks to Abishek Kulkarni's solution, on which this optimization is suggested.
It could be used as a wrapper function for returning a reference to a private constant data type. For example in a linked list you have the constants tail and head, and if you want to determine if a node is a tail or head node, then you can compare it with the value returned by that function.
Though any optimizer would most likely optimize it out anyway...
I removed the _SUCCESS file from the EMR output path in S3 and it worked fine.
In my case, with letsencrypt https, this was caused by using cert.pem
instead of fullchain.pem
as the certificate file on the requested server. See this thread for details.
Both methods are used by many of the large players. It's a matter of preference. My preference is REST because it's simpler to use and understand.
Simple Object Access Protocol (SOAP):
Representational state transfer (REST):
There are endless debates on REST vs SOAP on google.
My favorite is this one. Update 27 Nov 2013: Paul Prescod's site appears to have gone offline and this article is no longer available, copies though can be found on the Wayback Machine or as a PDF at CiteSeerX.
I'm successfully using the following to update options dynamically:
$control.select2('destroy').empty().select2({data: [{id: 1, text: 'new text'}]});
Something like this would let you take over the click of each internal link and scroll to the position of the corresponding bookmark:
$(function(){
$('a[href^=#]').click(function(e){
var name = $(this).attr('href').substr(1);
var pos = $('a[name='+name+']').offset();
$('body').animate({ scrollTop: pos.top });
e.preventDefault();
});
});
Solution found here : https://sourceforge.net/p/ipt-netflow/bugs-requests-patches/53/
The solution is : $(CURDIR)
You can use it like that :
CUR_DIR = $(CURDIR)
## Start :
start:
cd $(CUR_DIR)/path_to_folder
The first code line, Option Explicit
means (in simple terms) that all of your variables have to be explicitly declared by Dim
statements. They can be any type, including object, integer, string, or even a variant.
This line: Dim envFrmwrkPath As Range
is declaring the variable envFrmwrkPath
of type Range
. This means that you can only set it to a range.
This line: Set envFrmwrkPath = ActiveSheet.Range("D6").Value
is attempting to set the Range
type variable to a specific Value that is in cell D6
. This could be a integer or a string for example (depends on what you have in that cell) but it's not a range.
I'm assuming you want the value stored in a variable. Try something like this:
Dim MyVariableName As Integer
MyVariableName = ActiveSheet.Range("D6").Value
This assumes you have a number (like 5) in cell D6. Now your variable will have the value.
For simplicity sake of learning, you can remove or comment out the Option Explicit
line and VBA will try to determine the type of variables at run time.
Try this to get through this part of your code
Dim envFrmwrkPath As String
Dim ApplicationName As String
Dim TestIterationName As String
EDIT: using c++14, the best solution is very easy to write thanks to lambdas that can now have parameters of type auto
. This is my current favorite solution
std::sort(v.begin(), v.end(), [](auto &left, auto &right) {
return left.second < right.second;
});
Just use a custom comparator (it's an optional 3rd argument to std::sort
)
struct sort_pred {
bool operator()(const std::pair<int,int> &left, const std::pair<int,int> &right) {
return left.second < right.second;
}
};
std::sort(v.begin(), v.end(), sort_pred());
If you're using a C++11 compiler, you can write the same using lambdas:
std::sort(v.begin(), v.end(), [](const std::pair<int,int> &left, const std::pair<int,int> &right) {
return left.second < right.second;
});
EDIT: in response to your edits to your question, here's some thoughts ... if you really wanna be creative and be able to reuse this concept a lot, just make a template:
template <class T1, class T2, class Pred = std::less<T2> >
struct sort_pair_second {
bool operator()(const std::pair<T1,T2>&left, const std::pair<T1,T2>&right) {
Pred p;
return p(left.second, right.second);
}
};
then you can do this too:
std::sort(v.begin(), v.end(), sort_pair_second<int, int>());
or even
std::sort(v.begin(), v.end(), sort_pair_second<int, int, std::greater<int> >());
Though to be honest, this is all a bit overkill, just write the 3 line function and be done with it :-P
Although the actual problem was with the forward slash still for those using backslash but still saw \n in their layout.
Well i was also puzzled at first by why \n is not working in the layout but it seems that when you actually see that layout in an actual device it creates a line break so no need to worry what it shows on layout display screen your line breaks would be working perfectly fine on devices.
Easy solution in Python3+:
import time
todaysdate = time.strftime("%d/%m/%Y")
#with '.' isntead of '/'
todaysdate = time.strftime("%d.%m.%Y")
This will work for simnple data types (str, int, float, list etc.)
>>> def my_print(var_str) : print var_str+':', globals()[var_str] >>> a = 5 >>> b = ['hello', ',world!'] >>> my_print('a') a: 5 >>> my_print('b') b: ['hello', ',world!']
On Unix-like systems, dynamic linking can make life difficult for 'root' to use an application with the shared libraries installed in out-of-the-way locations. This is because the dynamic linker generally won't pay attention to LD_LIBRARY_PATH or its equivalent for processes with root privileges. Sometimes, then, static linking saves the day.
Alternatively, the installation process has to locate the libraries, but that can make it difficult for multiple versions of the software to coexist on the machine.
This can be done easily and cleanly with float
.

FPM is a process manager to manage the FastCGI SAPI (Server API) in PHP.
Basically, it replaces the need for something like SpawnFCGI. It spawns the FastCGI children adaptively (meaning launching more if the current load requires it).
Otherwise, there's not much operating difference between it and FastCGI (The request pipeline from start of request to end is the same). It's just there to make implementing it easier.
