The idea of non-blocking is that the loop iterations are quick. So to iterate for each tick should take short enough a time that the setTimeout will be accurate to within reasonable precision (off by maybe <100 ms or so).
In theory though you're right. If I write an application and block the tick, then setTimeouts will be delayed. So to answer you're question, who can assure setTimeouts execute on time? You, by writing non-blocking code, can control the degree of accuracy up to almost any reasonable degree of accuracy.
As long as javascript is "single-threaded" in terms of code execution (excluding web-workers and the like), that will always happen. The single-threaded nature is a huge simplification in most cases, but requires the non-blocking idiom to be successful.
Try this code out either in your browser or in node, and you'll see that there is no guarantee of accuracy, on the contrary, the setTimeout will be very late:
var start = Date.now();
// expecting something close to 500
setTimeout(function(){ console.log(Date.now() - start); }, 500);
// fiddle with the number of iterations depending on how quick your machine is
for(var i=0; i<5000000; ++i){}
Unless the interpreter optimises the loop away (which it doesn't on chrome), you'll get something in the thousands. Remove the loop and you'll see it's 500 on the nose...
If I understand you correctly, you want to compose a multipart request manually from an HTTP/REST console. The multipart format is simple; a brief introduction can be found in the HTML 4.01 spec. You need to come up with a boundary, which is a string not found in the content, let’s say HereGoes
. You set request header Content-Type: multipart/form-data; boundary=HereGoes
. Then this should be a valid request body:
--HereGoes
Content-Disposition: form-data; name="myJsonString"
Content-Type: application/json
{"foo": "bar"}
--HereGoes
Content-Disposition: form-data; name="photo"
Content-Type: image/jpeg
Content-Transfer-Encoding: base64
<...JPEG content in base64...>
--HereGoes--
Even if it's a late answer: I think this is still a very good question and IMHO Python (without additional libraries or toolkits like numpy) is still lacking a convenient method to access the indices of list elements according to a manually defined filter.
You could manually define a function, which provides that functionality:
def indices(list, filtr=lambda x: bool(x)):
return [i for i,x in enumerate(list) if filtr(x)]
print(indices([1,0,3,5,1], lambda x: x==1))
Yields: [0, 4]
In my imagination the perfect way would be making a child class of list and adding the indices function as class method. In this way only the filter method would be needed:
class MyList(list):
def __init__(self, *args):
list.__init__(self, *args)
def indices(self, filtr=lambda x: bool(x)):
return [i for i,x in enumerate(self) if filtr(x)]
my_list = MyList([1,0,3,5,1])
my_list.indices(lambda x: x==1)
I elaborated a bit more on that topic here: http://tinyurl.com/jajrr87
WARNING: Not for git newbies.
This comes up enough in my workflow that I've almost tried to write a new git command for it. The usual git stash
flow is the way to go but is a little awkward. I usually make a new commit first since if I have been looking at the changes, all the information is fresh in my mind and it's better to just start git commit
-ing what I found (usually a bugfix belonging on master that I discover while working on a feature branch) right away.
It is also helpful—if you run into situations like this a lot—to have another working directory alongside your current one that always have the
master
branch checked out.
So how I achieve this goes like this:
git commit
the changes right away with a good commit message.git reset HEAD~1
to undo the commit from current branch.Sometimes later (asynchronously), or immediately in another terminal window:
cd my-project-master
which is another WD sharing the same .git
git reflog
to find the bugfix I've just made.git cherry-pick SHA1
of the commit.Optionally (still asynchronous) you can then rebase (or merge) your feature branch to get the bugfix, usually when you are about to submit a PR and have cleaned your feature branch and WD already:
cd my-project
which is the main WD I'm working on.git rebase master
to get the bugfixes.This way I can keep working on the feature uninterrupted and not have to worry about git stash
-ing anything or having to clean my WD before a git checkout
(and then having the check the feature branch backout again.) and still have all my bugfixes goes to master
instead of hidden in my feature branch.
IMO git stash
and git checkout
is a real PIA when you are in the middle of working on some big feature.
I highly doubt it. You might want to use DTS/SSIS to do this as Levi says. One think that you might want to do is start the process without actually importing the data. Just do enough to get the basic table structures together. Then you are going to want to change around the resulting table structure, because whatever structure tat will likely be created will be shaky at best.
You might also have to take this a step further and create a staging area that takes in all the data first n a string (varchar) form. Then you can create a script that does validation and conversion to get it into the "real" database, because the two databases don't always work well together, especially when dealing with dates.
If you're using bash
version > 4.0, you can exploit shopt -s globstar
to make short work of this:
shopt -s globstar; tar -czvf deploy.tar.gz **/Alice*.yml **/Bob*.json
this will add all .yml files that starts with Alice from any sub-directory and add all .json files that starts with Bob from any sub-directory.

A pretty simple solution is to check for the screen width. Since almost all mobile devices have a max screen width of 480px (at present), it's pretty reliable:
if( screen.width <= 480 ) {
location.href = '/mobile.html';
}
The user-agent string is also a place to look. However, the former solution is still better since even if some freaking device does not respond correctly for the user-agent, the screen width doesn't lie.
The only exception here are tablet pc's like the ipad. Those devices have a higher screen width than smartphones and I would probably go with the user-agent-string for those.
inputs[5].addEventListener('keydown', enterNumbers);
function enterNumbers(event) {
if ((event.code == 'ArrowLeft') || (event.code == 'ArrowRight') ||
(event.code == 'ArrowUp') || (event.code == 'ArrowDown') ||
(event.code == 'Delete') || (event.code == 'Backspace')) {
return;
} else if (event.key.search(/\d/) == -1) {
event.preventDefault();
}
}
in this case, the value of the input field stays intact when a non-number button is pressed, and still delete, backspace, arrowup-down-left-right work properly and can be used for modifying the digital input.
try this one.. (guys I am a new bee.. so if I wrong then I am really sorry. But I found a solution by this way.)
var suggestion = [];
$('#health_condition_name:checked').each(function (j, ob) {
var odata = {
health_condition_name: $(ob).val()

This worked for me:
yum install python36-pyOpenSSL
python version and package manager might differ.
To cater for the schema as well, use this format in SQL 2014
if exists(select 1 from sys.views V inner join sys.[schemas] S on v.schema_id = s.schema_id where s.name='dbo' and v.name = 'someviewname' and v.type = 'v')
drop view [dbo].[someviewname];
go
And just throwing it out there, to do stored procedures, because I needed that too:
if exists(select 1
from sys.procedures p
inner join sys.[schemas] S on p.schema_id = s.schema_id
where
s.name='dbo' and p.name = 'someprocname'
and p.type in ('p', 'pc')
drop procedure [dbo].[someprocname];
go
For there to be an overlap the table's start_date has to be LESS THAN the interval end date (i.e. it has to start before the end of the interval) AND the table's end_date has to be GREATER THAN the interval start date. You may need to use <= and >= depending on your requirements.
This should clear your applications cache which should be where your webview cache is

if (children.length > 0) {
for (int i = 0; i < children.length; i++) {
File[] temp = children[i].listFiles();
for (int x = 0; x < temp.length; x++) {
temp[x].delete();
}
}

Remember, functions are internal to a script and normally return from whence they were called by using the return statement. Calling an external script is another matter entirely, and scripts usually terminate with an exit statement.
The difference "between the return and exit statement in Bash functions with respect to exit codes" is very small. Both return a status, not values per se. A status of zero indicates success, while any other status (1 to 255) indicates a failure. The return statement will return to the script from where it was called, while the exit statement will end the entire script from wherever it is encountered.
return 0 # Returns to where the function was called. $? contains 0 (success).
return 1 # Returns to where the function was called. $? contains 1 (failure).
exit 0 # Exits the script completely. $? contains 0 (success).
exit 1 # Exits the script completely. $? contains 1 (failure).
If your function simply ends without a return statement, the status of the last command executed is returned as the status code (and will be placed in $?
).
Remember, return and exit give back a status code from 0 to 255, available in $?
. You cannot stuff anything else into a status code (e.g., return "cat"); it will not work. But, a script can pass back 255 different reasons for failure by using status codes.
You can set variables contained in the calling script, or echo results in the function and use command substitution in the calling script; but the purpose of return and exit are to pass status codes, not values or computation results as one might expect in a programming language like C.
You could use very easily reflection to list all properties, methods and values.
For Gecko based browsers you can use the .toSource() method:
var data = new Object();
data["firstname"] = "John";
data["lastname"] = "Smith";
data["age"] = 21;
alert(data.toSource()); //Will return "({firstname:"John", lastname:"Smith", age:21})"
But since you use Firebug, why not just use console.log?
Another problem could be that the Android Project Build Target is not set.
How about this? (If you're using jQuery)
var $window = $(window);
var $body = $(window.document.body);
window.onscroll = function() {
var overlay = $body.children(".ui-widget-overlay").first();
// Check if the overlay is visible and restore the previous scroll state
if (overlay.is(":visible")) {
var scrollPos = $body.data("scroll-pos") || { x: 0, y: 0 };
window.scrollTo(scrollPos.x, scrollPos.y);
}
else {
// Just store the scroll state
$body.data("scroll-pos", { x: $window.scrollLeft(), y: $window.scrollTop() });
}
};

Use the enumerate()
function to generate the index along with the elements of the sequence you are looping over:
for index, w in enumerate(loopme):
print "CURRENT WORD IS", w, "AT CHARACTER", index
Perhaps I misunderstood the question but doesn't this do it?
int NumDigits(int x)
{
x = abs(x);
return (x < 10 ? 1 :
(x < 100 ? 2 :
(x < 1000 ? 3 :
(x < 10000 ? 4 :
(x < 100000 ? 5 :
(x < 1000000 ? 6 :
(x < 10000000 ? 7 :
(x < 100000000 ? 8 :
(x < 1000000000 ? 9 :

This problem take with me more than 3 hours finally , I just tried the problem was in removing dot from the end just .
problem was
docker run -p 3000:80 --rm --name test-con test-app .
/usr/local/bin/docker-entrypoint.sh: 8: exec: .: Permission denied
just remove dot from the end of your command line :
docker run -p 3000:80 --rm --name test-con test-app
I think that CONTAINS
took longer and used Merge
because you had a dash("-") in your query adventure-works.com
.
The dash is a break word so the CONTAINS
searched the full-text index for adventure
and than it searched for works.com
and merged the results.
function convertCase(str) {
var lower = String(str).toLowerCase();
return lower.replace(/(^| )(\w)/g, function(x) {

});
}
You want a pointer to the first element, so;
static uint8_t l_matrix[10][20];
void test(){
uint8_t *matrix_ptr = l_matrix[0]; //wrong idea
}
Define set
a = set()
Use add to append single values
a.add(1)
a.add(2)
Use update to add elements from tuples, sets, lists or frozen-sets
a.update([3,4])
>> print(a)
{1, 2, 3, 4}
If you want to add a tuple or frozen-set itself, use add
a.add((5, 6))
>> print(a)
{1, 2, 3, 4, (5, 6)}
Note: Since set elements must be hashable, and lists are considered mutable, you cannot add a list to a set. You also cannot add other sets to a set. You can however, add the elements from lists and sets as demonstrated with the ".update" method.
Python lists were not made to operate on the beginning of the list and are very ineffective at this operation.
While you can write
mylist = [1, 2 ,3 ,4]
mylist.pop(0)
It's very inefficient.
If you only want to delete items from your list, you can do this with del
:
del mylist[:n]
Which is also really fast:
In [34]: %%timeit
help=range(10000)
while help:
del help[:1000]
....:
10000 loops, best of 3: 161 µs per loop
If you need to obtain elements from the beginning of the list, you should use collections.deque
by Raymond Hettinger and its popleft()
method.
from collections import deque
deque(['f', 'g', 'h', 'i', 'j'])
>>> d.pop() # return and remove the rightmost item
'j'
>>> d.popleft() # return and remove the leftmost item
'f'
A comparison:
In [30]: %%timeit
....: help=range(10000)
....: while help:
....: help.pop(0)
....:
100 loops, best of 3: 17.9 ms per loop
In [33]: %%timeit
help=deque(range(10000))
while help:
help.popleft()
....:
1000 loops, best of 3: 812 µs per loop
I solve this problem with docker commit after some modifications in the base container, we only need to tag the new image and start that one
docs.docker.com/engine/reference/commandline/commit

Since the SERVICE_USER table is not a pure join table, but has additional functional fields (blocked), you must map it as an entity, and decompose the many to many association between User and Service into two OneToMany associations : One User has many UserServices, and one Service has many UserServices.
You haven't shown us the most important part : the mapping and initialization of the relationships between your entities (i.e. the part you have problems with). So I'll show you how it should look like.
If you make the relationships bidirectional, you should thus have
class User {
@OneToMany(mappedBy = "user")
private Set<UserService> userServices = new HashSet<UserService>();
}
class UserService {
@ManyToOne
@JoinColumn(name = "user_id")
private User user;
@ManyToOne
@JoinColumn(name = "service_code")
private Service service;
@Column(name = "blocked")
private boolean blocked;
}
class Service {
@OneToMany(mappedBy = "service")
private Set<UserService> userServices = new HashSet<UserService>();
}
If you don't put any cascade on your relationships, then you must persist/save all the entities. Although only the owning side of the relationship (here, the UserService side) must be initialized, it's also a good practice to make sure both sides are in coherence.
User user = new User();
Service service = new Service();
UserService userService = new UserService();
user.addUserService(userService);
userService.setUser(user);
service.addUserService(userService);
userService.setService(service);
session.save(user);
session.save(service);
session.save(userService);
window.location.reload();

An IDE which supports Android development is Processing for Android: http://wiki.processing.org/w/Android. Processing is its own language but it's easy to learn. Processing for Android requires the JDK and Android SDK to be installed but runs on its own. It runs on Linux, Mac OSX and Windows (on a side note: one can develop a desktop app in Processing and then compile it to target any of these operating systems). Its development is ongoing but it works. It's especially good for quickly sketching up an idea and running it on your Android phone (even if you plan to develop it further in another IDE).
There is an active support forum here: http://forum.processing.org/android-processing.
The problem with your code is that you are selecting the .remode_hover
that is a descendant of .remode_selected
. So the first part of getting your code to work correctly is by removing that space
.reMode_selected.reMode_hover:hover
Then, in order to get the style to not work, you have to override the style set by the :hover
. In other words, you need to counter the background-color
property. So the final code will be
.reMode_selected.reMode_hover:hover {
background-color:inherit;
}
.reMode_hover:hover {
background-color: #f0ac00;
}
An alternative method would be to use :not()
, as stated by others. This will return any element that doesn't have the class or property stated inside the parenthesis. In this case, you would put .remode_selected
in there. This will target all elements that don't have a class of .remode_selected
However, I would not recommend this method, because of the fact that it was introduced in CSS3, so browser support is not ideal.
A third method would be to use jQuery. You can target the .not()
selector, which would be similar to using :not()
in CSS, but with much better browser support
So - the solution of providing a base works given that all of the paths have the same base path. But if you want to provide different base paths, this still won't work.
One way I solved this problem was by making the beginning of the path relative. For your case:
gulp.src([
'index.php',
'*css/**/*',
'*js/**/*',
'*src/**/*',
])
.pipe(gulp.dest('/var/www/'));
The reason this works is that Gulp sets the base to be the end of the first explicit chunk - the leading * causes it to set the base at the cwd (which is the result that we all want!)
This only works if you can ensure your folder structure won't have certain paths that could match twice. For example, if you had randomjs/
at the same level as js
, you would end up matching both.
This is the only way that I have found to include these as part of a top-level gulp.src function. It would likely be simple to create a plugin/function that could separate out each of those globs so you could specify the base directory for them, however.
Difference between AbstractFactory and Factory design patterns are as follows:
Factory Method Pattern Implementation:
Abstract Factory Pattern Implementation:
// this will give all the forms on the page.
$('form')
// If you know the name of form then.
$('form[name="myFormName"]')
// If you don't know know the name but the position (starts with 0)
$('form:eq(1)') // 2nd form will be fetched.

With Pandas version =1.0.0, I would use DataFrame.replace
or Series.replace
:
df.replace(old_val, pd.NA, inplace=True)
This is better for two reasons:
pd.NA
instead of None
or np.nan
.There is another way of fetching certain information from your package.json
file namely using pkginfo module.
Usage of this module is very simple. You can get all package variables using:
require('pkginfo')(module);
Or only certain details (version
in this case)
require('pkginfo')(module, 'version');
And your package variables will be set to module.exports
(so version number will be accessible via module.exports.version
).
You could use the following code snippet:
require('pkginfo')(module, 'version');
console.log "Express server listening on port %d in %s mode %s", app.address().port, app.settings.env, module.exports.version
This module has very nice feature - it can be used in any file in your project (e.g. in subfolders) and it will automatically fetch information from your package.json
. So you do not have to worry where you package.json
is.
I hope that will help.
After placing the jar file in desired location, you need to add the jar file by right click on
Project --> properties --> Java Build Path --> Libraries --> Add Jar.
A Swift 3 solution along the lines of Sunkas's:
extension String {
mutating func replace(_ originalString:String, with newString:String) {
self = self.replacingOccurrences(of: originalString, with: newString)
}
}
Use:
var string = "foo!"
string.replace("!", with: "?")
print(string)
Output:
foo?
You also can take an array of keys with type []Value
by method MapKeys
of struct Value
from package "reflect":
package main
import (
"fmt"
"reflect"
)
func main() {
abc := map[string]int{
"a": 1,
"b": 2,
"c": 3,
}
keys := reflect.ValueOf(abc).MapKeys()
fmt.Println(keys) // [a b c]
}
There isn't much else to add other than what the docs say. If you want to dump the JSON into a file/socket or whatever, then you should go with dump()
. If you only need it as a string (for printing, parsing or whatever) then use dumps()
(dump string)
As mentioned by Antti Haapala in this answer, there are some minor differences on the ensure_ascii
behaviour. This is mostly due to how the underlying write()
function works, being that it operates on chunks rather than the whole string. Check his answer for more details on that.
json.dump()
Serialize obj as a JSON formatted stream to fp (a .write()-supporting file-like object
If ensure_ascii is False, some chunks written to fp may be unicode instances
json.dumps()
Serialize obj to a JSON formatted str
If ensure_ascii is False, the result may contain non-ASCII characters and the return value may be a unicode instance

To extract and print the text This is some
from the text node using Selenium's python client you have 2 ways as follows:
Using splitlines()
: You can identify the parent element i.e. <div id="a">
, extract the innerHTML
and then use splitlines()
as follows:
using xpath:
print(driver.find_element_by_xpath("//div[@id='a']").get_attribute("innerHTML").splitlines()[0])
using xpath:
print(driver.find_element_by_css_selector("div#a").get_attribute("innerHTML").splitlines()[0])
Using execute_script()
: You can also use the execute_script()
method which can synchronously execute JavaScript in the current window/frame as follows:
using xpath and firstChild:
parent_element = driver.find_element_by_xpath("//div[@id='a']")
print(driver.execute_script('return arguments[0].firstChild.textContent;', parent_element).strip())
using xpath and childNodes[n]:
parent_element = driver.find_element_by_xpath("//div[@id='a']")
print(driver.execute_script('return arguments[0].childNodes[1].textContent;', parent_element).strip())
Simply use one of the following methods.
<script type="text/javascript">
var js_variable = '<?php echo $php_variable;?>';
<script>
OR
<script type="text/javascript">
var js_variable = <?php echo json_encode($php_variable); ?>;
</script>
$('div').attr('style', '');
or
$('div').removeAttr('style');
(From Andres's Answer)
To make this a little smaller, try this:
$('div[style]').removeAttr('style');
This should speed it up a little because it checks that the divs have the style attribute.
Either way, this might take a little while to process if you have a large amount of divs, so you might want to consider other methods than javascript.
UPDATE 2020
You can do this with DateTimeOffset
DateTimeOffset dateTimeOffset = DateTimeOffset.FromUnixTimeSeconds(epochSeconds);
DateTimeOffset dateTimeOffset2 = DateTimeOffset.FromUnixTimeMilliseconds(epochMilliseconds);
And if you need the DateTime
object instead of DateTimeOffset
, then you can call the DateTime
property
DateTime dateTime = dateTimeOffset.DateTime;
I presume that you mean Unix time, which is defined as the number of seconds since midnight (UTC) on 1st January 1970.
private static readonly DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
public static DateTime FromUnixTime(long unixTime)
{
return epoch.AddSeconds(unixTime);
}
Put the desired launcher image (.png) in drawable folder.

A jQuery plugin based on M4N's answer
jQuery.fn.cssNumber = function(prop){
var v = parseInt(this.css(prop),10);
return isNaN(v) ? 0 : v;
};
So then you just use this method to get number values
$("#logo").cssNumber("top")
You can use is_uploaded_file()
:
if(!file_exists($_FILES['myfile']['tmp_name']) || !is_uploaded_file($_FILES['myfile']['tmp_name'])) {
echo 'No upload';
}
From the docs:
Returns TRUE if the file named by filename was uploaded via HTTP POST. This is useful to help ensure that a malicious user hasn't tried to trick the script into working on files upon which it should not be working--for instance, /etc/passwd.
This sort of check is especially important if there is any chance that anything done with uploaded files could reveal their contents to the user, or even to other users on the same system.
EDIT: I'm using this in my FileUpload class, in case it helps:
public function fileUploaded()
{
if(empty($_FILES)) {
return false;
}
$this->file = $_FILES[$this->formField];
if(!file_exists($this->file['tmp_name']) || !is_uploaded_file($this->file['tmp_name'])){
$this->errors['FileNotExists'] = true;
return false;
}
return true;
}
This should work
Integer i= Integer.parseInt(text.substring(text.length() - 7));
Put a breakpoint on the return
line.
You are running it in the debugger, right?
In this code you are not comparing string values, you are comparing pointer values. If you want to compare string values you need to use a string comparison function such as strcmp.
if ( 0 == strcmp(var1, "dev")) {
..
}
This works well:
{{ app('request')->input('a') }}
Where a
is the url parameter.

The most important difference is that gzip is only capable to compress a single file while zip compresses multiple files one by one and archives them into one single file afterwards. Thus, gzip comes along with tar most of the time (there are other possibilities, though). This comes along with some (dis)advantages.
If you have a big archive and you only need one single file out of it, you have to decompress the whole gzip file to get to that file. This is not required if you have a zip file.
On the other hand, if you compress 10 similiar or even identical files, the zip archive will be much bigger because each file is compressed individually, whereas in gzip in combination with tar a single file is compressed which is much more effective if the files are similiar (equal).
Here is a non-numpy solution:
>>> a = [[40, 10], [50, 11]]
>>> [float(sum(l))/len(l) for l in zip(*a)]
[45.0, 10.5]
Depends on what you're doing.
For instance:
//bankers' rounding - midpoint goes to nearest even
GetIntPart(2.5) >> 2
GetIntPart(5.5) >> 6
GetIntPart(-6.5) >> -6
or
//arithmetic rounding - midpoint goes away from zero
GetIntPart(2.5) >> 3
GetIntPart(5.5) >> 6
GetIntPart(-6.5) >> -7
The default is always the former, which can be a surprise but makes very good sense.
Your explicit cast will do:
int intPart = (int)343564564.5
// intPart will be 343564564
int intPart = (int)343564565.5
// intPart will be 343564566
From the way you've worded the question it sounds like this isn't what you want - you want to floor it every time.
I would do:
Math.Floor(Math.Abs(number));
Also check the size of your decimal
- they can be quite big, so you may need to use a long
.
Use the time.Now()
function and the time.Format()
method.
t := time.Now()
fmt.Println(t.Format("20060102150405"))
prints out 20110504111515
, or at least it did a few minutes ago. (I'm on Eastern Daylight Time.) There are several pre-defined time formats in the constants defined in the time package.
You can use time.Now().UTC()
if you'd rather have UTC than your local time zone.
On a rooted device you can:
// check that db is there
>adb shell
# ls /data/data/app.package.name/databases
db_name.sqlite // a custom named db
# exit
// pull it
>adb pull /data/app.package.name/databases/db_name.sqlite
You can get the port number by using server.address().port
like in below code:
var http = require('http');
var serverFunction = function (req, res) {
if (req.url == '/') {
console.log('get method');
res.writeHead(200, { 'content-type': 'text/plain' });
res.end('Hello World');
}
}
var server = http.createServer(serverFunction);
server.listen(3002, function () {
console.log('server is listening on port:', server.address().port);
});
when you use the svn:// URI it uses port 3690 and probably won't use http proxy

Adding to what @KyleMit said, consider using:
col-md-*
classes for the larger outer columnscol-xs-*
classes for the smaller inner columnsThis will be useful when you view the page on different screen sizes.
On a small screen, the wrapping of larger outer columns will then happen while maintaining the smaller inner columns, if possible
You'll need to create a new array if you want to add an index.
Try this:
public static void main(String[] args) {
int[] series = new int[0];
int x = 5;
series = addInt(series, x);
//print out the array with commas as delimiters
System.out.print("New series: ");
for (int i = 0; i < series.length; i++){
if (i == series.length - 1){
System.out.println(series[i]);
}
else{
System.out.print(series[i] + ", ");
}
}
}
// here, create a method
public static int[] addInt(int [] series, int newInt){
//create a new array with extra index
int[] newSeries = new int[series.length + 1];
//copy the integers from series to newSeries
for (int i = 0; i < series.length; i++){
newSeries[i] = series[i];
}
//add the new integer to the last index
newSeries[newSeries.length - 1] = newInt;
return newSeries;
}
Let me tell you first thing you cannot delete the DCIM folder because it is a system folder. As you delete it manually on phone it will delete the contents of that folder, but not the DCIM folder. You can delete its contents by using the method below:
Updated as per comments
File dir = new File(Environment.getExternalStorageDirectory()+"Dir_name_here");
if (dir.isDirectory())
{
String[] children = dir.list();
for (int i = 0; i < children.length; i++)
{
new File(dir, children[i]).delete();
}
}
Rewrite of a now-deleted answer by VonC.
Robert Gamble's succinct answer deals directly with the question. This one amplifies on some issues with filenames containing spaces.
See also: ${1:+"$@"} in /bin/sh
Basic thesis: "$@"
is correct, and $*
(unquoted) is almost always wrong.
This is because "$@"
works fine when arguments contain spaces, and
works the same as $*
when they don't.
In some circumstances, "$*"
is OK too, but "$@"
usually (but not
always) works in the same places.
Unquoted, $@
and $*
are equivalent (and almost always wrong).
So, what is the difference between $*
, $@
, "$*"
, and "$@"
? They are all related to 'all the arguments to the shell', but they do different things. When unquoted, $*
and $@
do the same thing. They treat each 'word' (sequence of non-whitespace) as a separate argument. The quoted forms are quite different, though: "$*"
treats the argument list as a single space-separated string, whereas "$@"
treats the arguments almost exactly as they were when specified on the command line.
"$@"
expands to nothing at all when there are no positional arguments; "$*"
expands to an empty string — and yes, there's a difference, though it can be hard to perceive it.
See more information below, after the introduction of the (non-standard) command al
.
Secondary thesis: if you need to process arguments with spaces and then
pass them on to other commands, then you sometimes need non-standard
tools to assist. (Or you should use arrays, carefully: "${array[@]}"
behaves analogously to "$@"
.)
Example:
$ mkdir "my dir" anotherdir
$ ls
anotherdir my dir
$ cp /dev/null "my dir/my file"
$ cp /dev/null "anotherdir/myfile"
$ ls -Fltr
total 0
drwxr-xr-x 3 jleffler staff 102 Nov 1 14:55 my dir/
drwxr-xr-x 3 jleffler staff 102 Nov 1 14:55 anotherdir/
$ ls -Fltr *
my dir:
total 0
-rw-r--r-- 1 jleffler staff 0 Nov 1 14:55 my file
anotherdir:
total 0
-rw-r--r-- 1 jleffler staff 0 Nov 1 14:55 myfile
$ ls -Fltr "./my dir" "./anotherdir"
./my dir:
total 0
-rw-r--r-- 1 jleffler staff 0 Nov 1 14:55 my file
./anotherdir:
total 0
-rw-r--r-- 1 jleffler staff 0 Nov 1 14:55 myfile
$ var='"./my dir" "./anotherdir"' && echo $var
"./my dir" "./anotherdir"
$ ls -Fltr $var
ls: "./anotherdir": No such file or directory
ls: "./my: No such file or directory
ls: dir": No such file or directory
$
Why doesn't that work?
It doesn't work because the shell processes quotes before it expands
variables.
So, to get the shell to pay attention to the quotes embedded in $var
,
you have to use eval
:
$ eval ls -Fltr $var
./my dir:
total 0
-rw-r--r-- 1 jleffler staff 0 Nov 1 14:55 my file
./anotherdir:
total 0
-rw-r--r-- 1 jleffler staff 0 Nov 1 14:55 myfile
$
This gets really tricky when you have file names such as "He said,
"Don't do this!"
" (with quotes and double quotes and spaces).
$ cp /dev/null "He said, \"Don't do this!\""
$ ls
He said, "Don't do this!" anotherdir my dir
$ ls -l
total 0
-rw-r--r-- 1 jleffler staff 0 Nov 1 15:54 He said, "Don't do this!"
drwxr-xr-x 3 jleffler staff 102 Nov 1 14:55 anotherdir
drwxr-xr-x 3 jleffler staff 102 Nov 1 14:55 my dir
$
The shells (all of them) do not make it particularly easy to handle such
stuff, so (funnily enough) many Unix programs do not do a good job of
handling them.
On Unix, a filename (single component) can contain any characters except
slash and NUL '\0'
.
However, the shells strongly encourage no spaces or newlines or tabs
anywhere in a path names.
It is also why standard Unix file names do not contain spaces, etc.
When dealing with file names that may contain spaces and other
troublesome characters, you have to be extremely careful, and I found
long ago that I needed a program that is not standard on Unix.
I call it escape
(version 1.1 was dated 1989-08-23T16:01:45Z).
Here is an example of escape
in use - with the SCCS control system.
It is a cover script that does both a delta
(think check-in) and a
get
(think check-out).
Various arguments, especially -y
(the reason why you made the change)
would contain blanks and newlines.
Note that the script dates from 1992, so it uses back-ticks instead of
$(cmd ...)
notation and does not use #!/bin/sh
on the first line.
: "@(#)$Id: delget.sh,v 1.8 1992/12/29 10:46:21 jl Exp $"
#
# Delta and get files
# Uses escape to allow for all weird combinations of quotes in arguments
case `basename $0 .sh` in
deledit) eflag="-e";;
esac
sflag="-s"
for arg in "$@"
do
case "$arg" in
-r*) gargs="$gargs `escape \"$arg\"`"
dargs="$dargs `escape \"$arg\"`"
;;
-e) gargs="$gargs `escape \"$arg\"`"
sflag=""
eflag=""
;;
-*) dargs="$dargs `escape \"$arg\"`"
;;
*) gargs="$gargs `escape \"$arg\"`"
dargs="$dargs `escape \"$arg\"`"
;;
esac
done
eval delta "$dargs" && eval get $eflag $sflag "$gargs"
(I would probably not use escape quite so thoroughly these days - it is
not needed with the -e
argument, for example - but overall, this is
one of my simpler scripts using escape
.)
The escape
program simply outputs its arguments, rather like echo
does, but it ensures that the arguments are protected for use with
eval
(one level of eval
; I do have a program which did remote shell
execution, and that needed to escape the output of escape
).
$ escape $var
'"./my' 'dir"' '"./anotherdir"'
$ escape "$var"
'"./my dir" "./anotherdir"'
$ escape x y z
x y z
$
I have another program called al
that lists its arguments one per line
(and it is even more ancient: version 1.1 dated 1987-01-27T14:35:49).
It is most useful when debugging scripts, as it can be plugged into a
command line to see what arguments are actually passed to the command.
$ echo "$var"
"./my dir" "./anotherdir"
$ al $var
"./my
dir"
"./anotherdir"
$ al "$var"
"./my dir" "./anotherdir"
$
[Added:
And now to show the difference between the various "$@"
notations, here is one more example:
$ cat xx.sh
set -x
al $@
al $*
al "$*"
al "$@"
$ sh xx.sh * */*
+ al He said, '"Don'\''t' do 'this!"' anotherdir my dir xx.sh anotherdir/myfile my dir/my file
He
said,
"Don't
do
this!"
anotherdir
my
dir
xx.sh
anotherdir/myfile
my
dir/my
file
+ al He said, '"Don'\''t' do 'this!"' anotherdir my dir xx.sh anotherdir/myfile my dir/my file
He
said,
"Don't
do
this!"
anotherdir
my
dir
xx.sh
anotherdir/myfile
my
dir/my
file
+ al 'He said, "Don'\''t do this!" anotherdir my dir xx.sh anotherdir/myfile my dir/my file'
He said, "Don't do this!" anotherdir my dir xx.sh anotherdir/myfile my dir/my file
+ al 'He said, "Don'\''t do this!"' anotherdir 'my dir' xx.sh anotherdir/myfile 'my dir/my file'
He said, "Don't do this!"
anotherdir
my dir
xx.sh
anotherdir/myfile
my dir/my file
$
Notice that nothing preserves the original blanks between the *
and */*
on the command line. Also, note that you can change the 'command line arguments' in the shell by using:
set -- -new -opt and "arg with space"
This sets 4 options, '-new
', '-opt
', 'and
', and 'arg with space
'.
]
Hmm, that's quite a long answer - perhaps exegesis is the better term.
Source code for escape
available on request (email to firstname dot
lastname at gmail dot com).
The source code for al
is incredibly simple:
#include <stdio.h>
int main(int argc, char **argv)
{
while (*++argv != 0)
puts(*argv);
return(0);
}
That's all. It is equivalent to the test.sh
script that Robert Gamble showed, and could be written as a shell function (but shell functions didn't exist in the local version of Bourne shell when I first wrote al
).
Also note that you can write al
as a simple shell script:
[ $# != 0 ] && printf "%s\n" "$@"
The conditional is needed so that it produces no output when passed no arguments. The printf
command will produce a blank line with only the format string argument, but the C program produces nothing.
Change Integrated security to false in the connection string.
You can check/verify this by opening up the SQL management studio with the username/password you have and see if you can connect/open the database from there. NOTE! Could be a firewall issue as well.

In my case, I did not change azure default security policy in management portal. The original is port 22 allowed and the rest are all denied. As long as I add 5432 port, everything becomes good.

You don't want git revert
. That undoes a previous commit. You want git checkout
to get git's version of the file from master.
git checkout -- filename.txt
In general, when you want to perform a git operation on a single file, use -- filename
.
2020 Update
Git introduced a new command git restore
in version 2.23.0
. Therefore, if you have git version 2.23.0+
, you can simply git restore filename.txt
- which does the same thing as git checkout -- filename.txt
. The docs for this command do note that it is currently experimental.
Attribute_Brands is a named range.
On any worksheet (tab) press F5 and type Attribute_Brands into the reference box and click on the OK button.
This will take you to the named range.
The data in it can be updated by typing new values into the cells.
The named range can be altered via the 'Insert - Name - Define' menu.
Nicely explained above!
For all those who may suffer like me to get this working in a localized Windows (mine is XP in Slovak), you may try to replace the %
with a !
So:

You can turn off the behavior AND and warning by exporting GIT_DISCOVERY_ACROSS_FILESYSTEM=1
.
On heroku, if you heroku config:set GIT_DISCOVERY_ACROSS_FILESYSTEM=1
the warning will go away.
It's probably because you are building a gem from source and the gemspec shells out to git
, like many do today. So, you'll still get the warning fatal: Not a git repository (or any of the parent directories): .git
but addressing that is for another day :)
My answer is a duplicate of: - comment GIT_DISCOVERY_ACROSS_FILESYSTEM problem when working with terminal and MacFusion
Since the img is an inline element, Just use text-center
on it's container. Using mx-auto
will center the container (column) too.
<div class="row">
<div class="col-4 mx-auto text-center">
<img src="..">
</div>
</div>
By default, images are display:inline
. If you only want the center the image (and not the other column content), make the image display:block
using the d-block
class, and then mx-auto
will work.
<div class="row">
<div class="col-4">
<img class="mx-auto d-block" src="..">
</div>
</div>
This is because in this case the char
type is signed on your system*. When this happens, the data gets sign-extended during the default conversions while passing the data to the function with variable number of arguments. Since 212 is greater than 0x80, it's treated as negative, %u
interprets the number as a large positive number:
212 = 0xD4
When it is sign-extended, FF
s are pre-pended to your number, so it becomes
0xFFFFFFD4 = 4294967252
which is the number that gets printed.
Note that this behavior is specific to your implementation. According to C99 specification, all char
types are promoted to (signed) int
, because an int
can represent all values of a char
, signed or unsigned:
6.1.1.2: If an
int
can represent all values of the original type, the value is converted to anint
; otherwise, it is converted to anunsigned int
.
This results in passing an int
to a format specifier %u
, which expects an unsigned int
.
To avoid undefined behavior in your program, add explicit type casts as follows:
unsigned char ch = (unsigned char)212;
printf("%u", (unsigned int)ch);
char
up to the implementation. See this question for more details.

If you are still having issues, try running these steps from VMware to disable credential guard. Worked for me, finally. Steps and link are posted below, not taking credit for them.
Original content from https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2146361
To disable Device Guard or Credential Guard on Itanium based computers:
Disable the group policy setting that was used to enable Credential Guard.
On the host operating system, click Start > Run, type gpedit.msc, and click Ok. The Local group Policy Editor opens.
Go to Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security.
Select Disabled.
Go to Control Panel > Programs and Features > Turn Windows features on or off to turn off Hyper-V. [ remove a program on Windows 8 or earlier]
Select Do not restart.
Delete the related EFI variables by launching a command prompt on the host machine using an Administrator account and run these commands:
enter code here
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,DISABLE-VBS
bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:
mountvol X: /d
Note: Ensure X is an unused drive, else change to another drive.
Restart the host.
Accept the prompt on the boot screen to disable Device Guard or Credential Guard.
You should be able to install and start HAXM now
This answer is focused to someone that buy a domain in another site (as GoDaddy) and want to use the Amazon free certificate with Certificate Manager
This answer uses Amazon Classic Load Balancer (paid) see the pricing before using it
Step 1 - Request a certificate with Certificate Manager
Go to Certificate Manager > Request Certificate > Request a public certificate
On Domain name you will add myprojectdomainname.com
and *.myprojectdomainname.com
and go on Next
Chose Email validation and Confirm and Request
Open the email that you have received (on the email account that you have buyed the domain) and aprove the request
After this, check if the validation status of myprojectdomainname.com
and *.myprojectdomainname.com
is sucess, if is sucess you can continue to Step 2
Step 2 - Create a Security Group to a Load Balancer
On EC2 go to Security Groups > and Create a Security Group and add the http and https inbound
Step 3 - Create the Load Balancer
EC2 > Load Balancer > Create Load Balancer > Classic Load Balancer (Third option)
Create LB inside - the vpc of your project On Load Balancer Protocol add Http and Https
Next > Select exiting security group
Choose the security group that you have create in the previous step
Next > Choose certificate from ACM
Select the certificate of the step 1
Next >
on Health check i've used the ping path / (one slash instead of /index.html)
Step 4 - Associate your instance with the security group of load balancer
EC2 > Instances > click on your project > Actions > Networking > Change Security Groups
Add the Security Group of your Load Balancer
Step 5
EC2 > Load Balancer > Click on the load balancer that you have created > copy the DNS Name (A Record), it will be something like myproject-2021611191.us-east-1.elb.amazonaws.com
Go to Route 53 > Routes Zones > click on the domain name > Go to Records Sets
(If you are don't have your domain here, create a hosted zone with Domain Name: myprojectdomainname.com
and Type: Public Hosted Zone
)
Check if you have a record type A (probably not), create/edit record set with name empty, type A, alias Yes and Target the dns that you have copied
Create also a new Record Set of type A, name *.myprojectdomainname.com
, alias Yes and Target your domain (myprojectdomainname.com). This will make possible access your site with www.myprojectdomainname.com and subsite.myprojectdomainname.com. Note: You will need to configure your reverse proxy (Nginx/Apache) to do so.
On NS copy the 4 Name Servers values to use on the next Step, it will be something like:
ns-362.awsdns-45.com
ns-1558.awsdns-02.co.uk
ns-737.awsdns-28.net
ns-1522.awsdns-62.org
Go to EC2 > Instances > And copy the IPv4 Public IP too
Step 6
On the domain register site that you have buyed the domain (in my case GoDaddy)
Change the routing to http : <Your IPv4 Public IP Number>
and select Forward with masking
Change the Name Servers (NS) to the 4 NS that you have copied, this can take 48 hours to make effect
simply set the height to auto, that should fix the problem, because div are block elements so they stretch out to full width and height of any element contained in it. if height set to auto not working then simple don't add the height, it should adjust and make sure that the div is not inheriting any height from it's parent element as well...
Use simple one line code for email Validation
public static boolean isValidEmail(CharSequence target) {
return !TextUtils.isEmpty(target) && android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches();
}
use like...
if (!isValidEmail(yourEdittext.getText().toString()) {
Toast.makeText(context, "your email is not valid", 2000).show();
}
You could look at "XpathNavigator.Evaluate" I have used this to process mathematical expressions for my GridView and it works fine for me.
Here is the code I used for my program:
public static double Evaluate(string expression)
{
return (double)new System.Xml.XPath.XPathDocument
(new StringReader("<r/>")).CreateNavigator().Evaluate
(string.Format("number({0})", new
System.Text.RegularExpressions.Regex(@"([\+\-\*])")
.Replace(expression, " ${1} ")
.Replace("/", " div ")
.Replace("%", " mod ")));
}
Just use the formula
120 = (HOUR(A8)*3600+MINUTE(A8)*60+SECOND(A8))/60
Using a text editor, check for ^M
(control-M, or carriage return) at the end of each line. You will need to remove them first, then append the additional text at the end of the line.
sed -i 's|^M||g' ips.txt
sed -i 's|$|:80|g' ips.txt
This may work for you, Please try this.

Which Log file? Well -- you can check the physical path by right-clicking on the System Log (e.g. Server Manager | Diagnostics | Event Viewer | Windows Logs). The default physical path is %SystemRoot%\System32\Winevt\Logs\System.evtx
.
You can create a Custom Filter and filter by "Source: WAS" to quickly see only entries generated by IIS.
You may need first to enable logging of such even for a specific App Pool -- by default App Pool has only 3 recycle events out of 8 enabled. To change it using GUI: II S Manager | Application Pools | Select App Pool -> Advanced Settings | Generate Recycle Event Log Entry.
The advantage of using JScript for classic ASP pages is that you can use one of the many, many libraries that have been written for JavaScript.
Like this one: https://github.com/gkindel/CSV-JS. Download it, include it in your ASP page, parse CSV with it.
<%@ language="javascript" %>
<script language="javascript" runat="server" src="scripts/csv.js"></script>
<script language="javascript" runat="server">
var text = '123,2.99,AMO024,Title,"Description, more info",,123987564',
rows = CSV.parse(line);
Response.Write(rows[0][4]);
</script>
You can use the wget --user=USER --password=PASSWORD ..
command, but before you can do that, you must allow artifactory to force authentication, which can be done by unchecking the "Hide Existence of Unauthorized Resources" box at Security/General tab in artifactory admin panel. Otherwise artifactory sends a 404 page and wget can not authenticate to artifactory.
I got a nice solution inspired by Apple's Table View Animations and Gestures. I deleted unnecessary parts from Apple's sample and translated it into swift.
I know the answer is quite long, but all the code is necessary. Fortunately, you can just copy and paste most of the code and just need to do a bit modification on step 1 and 3
1.create SectionHeaderView.swift
and SectionHeaderView.xib
import UIKit
protocol SectionHeaderViewDelegate {
func sectionHeaderView(sectionHeaderView: SectionHeaderView, sectionOpened: Int)
func sectionHeaderView(sectionHeaderView: SectionHeaderView, sectionClosed: Int)
}
class SectionHeaderView: UITableViewHeaderFooterView {
var section: Int?
@IBOutlet weak var titleLabel: UILabel!
@IBOutlet weak var disclosureButton: UIButton!
@IBAction func toggleOpen() {
self.toggleOpenWithUserAction(true)
}
var delegate: SectionHeaderViewDelegate?
func toggleOpenWithUserAction(userAction: Bool) {
self.disclosureButton.selected = !self.disclosureButton.selected
if userAction {
if self.disclosureButton.selected {
self.delegate?.sectionHeaderView(self, sectionClosed: self.section!)
} else {
self.delegate?.sectionHeaderView(self, sectionOpened: self.section!)
}
}
}
override func awakeFromNib() {
var tapGesture: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "toggleOpen")
self.addGestureRecognizer(tapGesture)
// change the button image here, you can also set image via IB.
self.disclosureButton.setImage(UIImage(named: "arrow_up"), forState: UIControlState.Selected)
self.disclosureButton.setImage(UIImage(named: "arrow_down"), forState: UIControlState.Normal)
}
}
the SectionHeaderView.xib
(the view with gray background) should look something like this in a tableview(you can customize it according to your needs, of course):
note:
a) the toggleOpen
action should be linked to disclosureButton
b) the disclosureButton
and toggleOpen
action are not necessary. You can delete these 2 things if you don't need the button.
2.create SectionInfo.swift
import UIKit
class SectionInfo: NSObject {
var open: Bool = true
var itemsInSection: NSMutableArray = []
var sectionTitle: String?
init(itemsInSection: NSMutableArray, sectionTitle: String) {
self.itemsInSection = itemsInSection
self.sectionTitle = sectionTitle
}
}
3.in your tableview
import UIKit
class TableViewController: UITableViewController, SectionHeaderViewDelegate {
let SectionHeaderViewIdentifier = "SectionHeaderViewIdentifier"
var sectionInfoArray: NSMutableArray = []
override func viewDidLoad() {
super.viewDidLoad()
let sectionHeaderNib: UINib = UINib(nibName: "SectionHeaderView", bundle: nil)
self.tableView.registerNib(sectionHeaderNib, forHeaderFooterViewReuseIdentifier: SectionHeaderViewIdentifier)
// you can change section height based on your needs
self.tableView.sectionHeaderHeight = 30
// You should set up your SectionInfo here
var firstSection: SectionInfo = SectionInfo(itemsInSection: ["1"], sectionTitle: "firstSection")
var secondSection: SectionInfo = SectionInfo(itemsInSection: ["2"], sectionTitle: "secondSection"))
sectionInfoArray.addObjectsFromArray([firstSection, secondSection])
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return sectionInfoArray.count
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if self.sectionInfoArray.count > 0 {
var sectionInfo: SectionInfo = sectionInfoArray[section] as! SectionInfo
if sectionInfo.open {
return sectionInfo.open ? sectionInfo.itemsInSection.count : 0
}
}
return 0
}
override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let sectionHeaderView: SectionHeaderView! = self.tableView.dequeueReusableHeaderFooterViewWithIdentifier(SectionHeaderViewIdentifier) as! SectionHeaderView
var sectionInfo: SectionInfo = sectionInfoArray[section] as! SectionInfo
sectionHeaderView.titleLabel.text = sectionInfo.sectionTitle
sectionHeaderView.section = section
sectionHeaderView.delegate = self
let backGroundView = UIView()
// you can customize the background color of the header here
backGroundView.backgroundColor = UIColor(red:0.89, green:0.89, blue:0.89, alpha:1)
sectionHeaderView.backgroundView = backGroundView
return sectionHeaderView
}
func sectionHeaderView(sectionHeaderView: SectionHeaderView, sectionOpened: Int) {
var sectionInfo: SectionInfo = sectionInfoArray[sectionOpened] as! SectionInfo
var countOfRowsToInsert = sectionInfo.itemsInSection.count
sectionInfo.open = true
var indexPathToInsert: NSMutableArray = NSMutableArray()
for i in 0..<countOfRowsToInsert {
indexPathToInsert.addObject(NSIndexPath(forRow: i, inSection: sectionOpened))
}
self.tableView.insertRowsAtIndexPaths(indexPathToInsert as [AnyObject], withRowAnimation: .Top)
}
func sectionHeaderView(sectionHeaderView: SectionHeaderView, sectionClosed: Int) {
var sectionInfo: SectionInfo = sectionInfoArray[sectionClosed] as! SectionInfo
var countOfRowsToDelete = sectionInfo.itemsInSection.count
sectionInfo.open = false
if countOfRowsToDelete > 0 {
var indexPathToDelete: NSMutableArray = NSMutableArray()
for i in 0..<countOfRowsToDelete {
indexPathToDelete.addObject(NSIndexPath(forRow: i, inSection: sectionClosed))
}
self.tableView.deleteRowsAtIndexPaths(indexPathToDelete as [AnyObject], withRowAnimation: .Top)
}
}
}
Ok, well I looked at the provided samples from rrainn and Soonil, and I found a solution that does not mess up error handling.
I modified the CustomExceptionHandler so it stores the original UncaughtExceptionHandler from the Thread we associate the new one. At the end of the new "uncaughtException"- Method I just call the old function using the stored UncaughtExceptionHandler.
In the DefaultExceptionHandler class you need sth. like this:
public class DefaultExceptionHandler implements UncaughtExceptionHandler{
private UncaughtExceptionHandler mDefaultExceptionHandler;
//constructor
public DefaultExceptionHandler(UncaughtExceptionHandler pDefaultExceptionHandler)
{
mDefaultExceptionHandler= pDefaultExceptionHandler;
}
public void uncaughtException(Thread t, Throwable e) {
//do some action like writing to file or upload somewhere
//call original handler
mStandardEH.uncaughtException(t, e);
// cleanup, don't know if really required
t.getThreadGroup().destroy();
}
}
With that modification on the code at http://code.google.com/p/android-remote-stacktrace you have a good working base for logging in the field to your webserver or to sd-card.
Try using the Format
function:
Private Sub btncalc_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles btncalc.Click
txtA.Text = Format(Val(txtD.Text) / Val(txtC.Text) *
Val(txtF.Text) / Val(txtE.Text), "0.00")
txtB.Text = Format(Val(txtA.Text) * 1000 / Val(txtG.Text), "0.00")
End Sub
well, I know that I'm a bit too late, but I tried all of your solutions and with no success!
So here is how I managed to do it.
First of all, I'm working on an Asp.Net MVC project.
The Only thing I changed was in my c# method getInvitation
:
public ActionResult getInvitation (Guid s_ID)
{
using (var db = new cRM_Verband_BWEntities())
{
var listSidsMit = (from data in db.TERMINEINLADUNGEN where data.RECID_KOMMUNIKATIONEN == s_ID select data.RECID_MITARBEITER.ToString()).ToArray();
return Json(listSidsMit);
}
}
SuccessFunction in JS :
function successFunction(result) {
console.log(result);
}
I changed the Method Type from string[]
to ActionResult
and of course at the end I wrapped my array listSidsMit
with the Json method.
#include <stdio.h>
#include <string.h>
int main(void){
char word[17], outword[33];//17:16+1, 33:16*2+1
int i, len;
printf("Intro word:");
fgets(word, sizeof(word), stdin);
len = strlen(word);
if(word[len-1]=='\n')
word[--len] = '\0';
for(i = 0; i<len; i++){
sprintf(outword+i*2, "%02X", word[i]);
}
printf("%s\n", outword);
return 0;
}
On the side note: if you have all of the files locally (not only wsdl file but also xsd files) you can invoke wsdl.exe in that manner:
wsdl.exe [path to your wsdl file] [paths to xsd files imported by wsdl]
That way wsdl.exe can resolve all dependecies locally and correctly generates proxy class.
Maybe it will save somebody some time - it solves "missing type" error when service is not avaliable online.

Laravel 5 uses .env
file to configure your app. .env
should not be committed on your repository, like github or bitbucket. On your local environment your .env
will look like the following:
# .env
APP_ENV=local
For your production server, you might have the following config:
# .env
APP_ENV=production
You get this error when the function isn't on the MATLAB path or in pwd.
First, make sure that you are able to find the function using:
>> which divrat
c:\work\divrat\divrat.m
If it returns:
>> which divrat
'divrat' not found.
It is not on the MATLAB path or in PWD.
Second, make sure that the directory that contains divrat
is on the MATLAB path using the PATH
command. It may be that a directory that you thought was on the path isn't actually on the path.
Finally, make sure you aren't using a "private" directory. If divrat
is in a directory named private, it will be accessible by functions in the parent directory, but not from the MATLAB command line:
>> foo
ans =
1
>> divrat(1,1)
??? Undefined function or method 'divrat' for input arguments of type 'double'.
>> which -all divrat
c:\work\divrat\private\divrat.m % Private to divrat
package will generate Jar/war as per POM file. install will install generated jar file to the local repository for other dependencies if any.

Starting Python 3.8
, the standard library provides the NormalDist
object as part of the statistics
module.
It can be used to get the inverse cumulative distribution function (inv_cdf
- inverse of the cdf
), also known as the quantile function or the percent-point function for a given mean (mu
) and standard deviation (sigma
):
from statistics import NormalDist
NormalDist(mu=10, sigma=2).inv_cdf(0.95)
# 13.289707253902943
Which can be simplified for the standard normal distribution (mu = 0
and sigma = 1
):
NormalDist().inv_cdf(0.95)
# 1.6448536269514715
On mobile devices (with Chrome for Android or Opera Mobile) you can detect zoom by window.visualViewport.scale. https://developer.mozilla.org/en-US/docs/Web/API/Visual_Viewport_API
Detect on Safari: document.documentElement.clientWidth / window.innerWidth (return 1 if no zooming on device).
This is more of an important comment. Sharing references of sytanx that is acceptable out of the box. For hack solutions look at other answers.
Per Apple's docs, Action Method Definitions have to be either one of these three. Anything else is unaccepted.

Not out of the box in Sql Server Management Studio, but it is a feature of the very good SSMS Tools Pack
Why not simply try this:
var promise = $http.get(url, {
params: query
}).then(function(response) {
console.log('Content-Range: ' + response.headers('Content-Range'));
return response.data;
});
Especially if you want to return the promise
so it could be a part of a promises chain.
For encoding/decoding numbers to/from byte sequences, there's the encoding/binary package. There are examples in the documentation: see the Examples section in the table of contents.
These encoding functions operate on io.Writer interfaces. The net.TCPConn type implements io.Writer, so you can write/read directly to network connections.
If you've got a Go program on either side of the connection, you may want to look at using encoding/gob. See the article "Gobs of data" for a walkthrough of using gob (skip to the bottom to see a self-contained example).
To simulate a click on an anchor while landing on a page, I just used jQuery to animate the scrollTop property in $(document).ready.
No need for a complex trigger, and that works on IE 6 and every other browser.
LocalDate ld ....;

ld.isEqual(LocalDate.from(ldtime));
Had been wrecking my head on symlinking node .. and nothing seemed to work...but finally what worked is setting the right permissions . This 'sudo chown -R $(whoami) /usr/local' did the work for me.
Go to the SQL Server Management Studio, navigate to Security, go to Logins and right click it. A Menu will come up with a button saying "New Login". There you will be able to add users and/or groups from Active Directory to your SQL Server "permissions". Hope this helps
It seems to me, that it is by design that this file is empty.
A similar question has been asked here: https://stackoverflow.com/questions/2567432/ubuntu-apache-httpd-conf-or-apache2-conf
So, you should have a look for /etc/apache2/apache2.conf
I have also seen:
if(length(obj)) {
# do this if object has length
# NULL has no length
}
I don't think it's great though. Because some vectors can be of length 0. character(0)
, logical(0)
, integer(0)
and that might be treated as a NULL instead of an error.
You can do this with pure CSS but you will need to hard code the offset scroll amounts, which may not be ideal should you be changing page content- or should dimensions of your content change on say window resize.
You're likely best placed to use e.g. jQuery, specifically:
$('html, body').stop().animate({
scrollTop: element.offset().top
}, 1000);
A complete implementation may be:
$('#up, #down').on('click', function(e){
e.preventDefault();
var target= $(this).get(0).id == 'up' ? $('#down') : $('#up');
$('html, body').stop().animate({
scrollTop: target.offset().top
}, 1000);
});
Where element
is the target element to scroll to and 1000
is the delay in ms before completion.
The benefit being, no matter what changes to your content dimensions, the function will not need to be altered.
given your example above - to find processes attached to shmid 98306
lsof | egrep "98306|COMMAND"
From so many answers in this website I didn't find out a clear answer so in 5-10 minutes I figured it out the answer myself. But this can be done in two cases:
So, let's assume we search for the substring "cd" in the string "abcde", and we use the simplest substr built-in function in C++
for 1:
#include <iostream>
#include <string>
using namespace std;
int i;
int main()
{
string a = "abcde";
string b = a.substr(2,2); // 2 will be c. Why? because we start counting from 0 in a string, not from 1.
cout << "substring of a is: " << b << endl;
return 0;
}
for 2:
#include <iostream>
#include <string>
using namespace std;
int i;
int main()
{
string a = "abcde";
for (i=0;i<a.length(); i++)
{
if (a.substr(i,2) == "cd")
{
cout << "substring of a is: " << a.substr(i,2) << endl; // i will iterate from 0 to 5 and will display the substring only when the condition is fullfilled
}
}
return 0;
}
I had this problem, it is for foreign-key
Click on the Relation View
(like the image below) then find name of the field you are going to remove it, and under the Foreign key constraint (INNODB)
column, just put the select to nothing! Means no foreign-key
Hope that works!
Sometimes (not often!) you do truly know more about past, current and future memory usage then the run time does. This does not happen very often, and I would claim never in a web application while normal pages are being served.
Many year ago I work on a report generator, that
Firstly as it was not real time and the users expected to wait for a report, a delay while the GC run was not an issue, but we needed to produce reports at a rate that was faster than they were requested.
Looking at the above outline of the process, it is clear that.
Therefore clearly it was well worth while doing a GC run whenever the request queue was empty; there was no downside to this.
It may be worth doing a GC run after each report is emailed, as we know this is a good time for a GC run. However if the computer had enough ram, better results would be obtained by delaying the GC run.
This behaviour was configured on a per installation bases, for some customers enabling a forced GC after each report greatly speeded up the protection of reports. (I expect this was due to low memory on their server and it running lots of other processes, so hence a well time forced GC reduced paging.)
We never detected an installation that did not benefit was a forced GC run every time the work queue was empty.
With MSSQL you can do something like this:
declare @result varchar(500)
set @result = ''
select @result = @result + ModuleValue + ', '
from TableX where ModuleId = @ModuleId
The solution consists in a regex pattern matching open and closing parenthesis
String str = "Your(String)";
// parameter inside split method is the pattern that matches opened and closed parenthesis,
// that means all characters inside "[ ]" escaping parenthesis with "\\" -> "[\\(\\)]"
String[] parts = str.split("[\\(\\)]");
for (String part : parts) {
// I print first "Your", in the second round trip "String"
System.out.println(part);
}
Writing in Java 8's style, this can be solved in this way:
Arrays.asList("Your(String)".split("[\\(\\)]"))
.forEach(System.out::println);
I hope it is clear.
When your program is waiting for I/O (ie. a disk read/write or network read/write etc), the CPU is free to do other tasks even if your program is stopped. The speed of your program will mostly depend on how fast that IO can happen, and if you want to speed it up you will need to speed up the I/O.
If your program is running lots of program instructions and not waiting for I/O, then it is said to be CPU bound. Speeding up the CPU will make the program run faster.
In either case, the key to speeding up the program might not be to speed up the hardware, but to optimize the program to reduce the amount of IO or CPU it needs, or to have it do I/O while it also does CPU intensive stuff.
Give another go at force removing the brewed version of git
brew uninstall --force git
Then cleanup any older versions and clear the brew cache
brew cleanup -s git
Remove any dead symlinks
brew cleanup --prune-prefix
Then try reinstalling git
brew install git
If that doesn't work, I'd remove that installation of Homebrew altogether and reinstall it. If you haven't placed anything else in your brew --prefix
directory (/usr/local
by default), you can simply rm -rf $(brew --prefix)
. Otherwise the Homebrew wiki recommends using a script at https://gist.github.com/mxcl/1173223#file-uninstall_homebrew-sh
You can run 20 processes and use the command:
wait
Your script will wait and continue when all your background jobs are finished.
Try wrapping whatever div you have flexboxed with flex-direction: column
in a container that is also flexboxed.
I just tested this in IE11 and it works. An odd fix, but until Microsoft makes their internal bug fix external...it'll have to do!
HTML:
<div class="FlexContainerWrapper">
<div class="FlexContainer">
<div class="FlexItem">
<p>I should be centered.</p>

Is there any way that I can start android emulator for intel x86 atom Without hardware acceleration on windows 8
Not with the standard Android SDK emulator, as it requires Intel's HAXM, and HAXM wants virtualization extensions to be enabled.
Whether Genymotion or something else from another independent developer can support your desired combination, I cannot say.

There are two ways in which this can be accomplished using vanilla javascript. The first is className
and the second is classList
. className
works in all browsers but can be unwieldy to work with when modifying an element's class attribute. classList
is an easier way to modify an element's class(es).
To outright set an element's class attribute, className
is the way to go, otherwise to modify an element's class(es), it's easier to use classList
.
Initial Html
<div id="ID"></div>
Setting the class attribute
var div = document.getElementById('ID');
div.className = "foo bar car";
Result:
<div id="ID" class="foo bar car"></div>
Adding a class
div.classList.add("car");// Class already exists, nothing happens
div.classList.add("tar");
Note: There's no need to test if a class exists before adding it. If a class needs to be added, just add it. If it already exists, a duplicate won't be added.
Result:
<div id="ID" class="foo bar car tar"></div>
Removing a class
div.classList.remove("car");
div.classList.remove("tar");
div.classList.remove("car");// No class of this name exists, nothing happens
Note: Just like add
, if a class needs to be removed, remove it. If it's there, it'll be removed, otherwise nothing will happen.
Result:
<div id="ID" class="foo bar"></div>
Checking if a class attribute contains a specific class
if (div.classList.contains("foo")) {
// Do stuff
}
Toggling a class
var classWasAdded = div.classList.toggle("bar"); // "bar" gets removed
// classWasAdded is false since "bar" was removed
classWasAdded = div.classList.toggle("bar"); // "bar" gets added
// classWasAdded is true since "bar" was added
.toggle
has a second boolean parameter that, in my opinion, is redundant and isn't worth going over.
For more information on classList
, check out MDN. It also covers browser compatibility if that's a concern, which can be addressed by using Modernizr for detection and a polyfill if needed.
The issue is this, you want to know if the error is not empty.
public function getError() {
return $this->error;
}
Adding a method isErrorSet() will solve the problem.
public function isErrorSet() {
if (isset($this->error) && !empty($this->error)) {
return true;
} else {
return false;
}
}
Now this will work fine with this code with no notice.
if (!($x->isErrorSet())) {
echo $x->getError();
}

print(current_process_pid) # e.g 12971
# Get pids by program name
program_name = 'chrome'

After spending an entire day fighting with myself on deciding to host my asp.net core application on IIS with InProcess hosting, i am finally proud and relieved to have this solved. Hours of repeatedly going through the same forums, blogs and SO questions which tried their best to solve the problem, i was still stuck after following all the above mentioned approaches. Now here i will describe my experience of solving it.
Step 1: Create a website in IIS
Step 2: Make sure the AppPool for the website has .Net CLR version set to "No Managed Code" and "Enable 32-bit Applications" property in AppPool -> Advanced Settings is set to false
Step 3: Make sure your project is referencing .Net core 2.2
Step 4: Add the following line in your startup.cs file inside ConfigureServices method
services.Configure<IISServerOptions>(options =>
{
options.AutomaticAuthentication = false;
});
Step 6: Add the following Nuget packages
Microsoft.AspNetCore.App v2.2.5 or greater
Microsoft.AspNetCore.Server.IIS v2.2.2 or greater
Step 7: Add following line to your .csproj file
<AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
Step 8: Build and publish your code (preferably x64 bitness)
Step 9: Make sure you added your website hostname in etc/hosts file
Step 10: Restart World Wide Web Publishing Service
Now test your asp.net core application and it should be hosted using InProcess hosting In order to verify whether your app is hosted using InProcess mode, check the response headers and it should contain the following line
Server: Microsoft-IIS/10.0 (IIS version could be any depeding on your system)
Update: Download and Install ASP.Net Core Hosting Bundle which is required for it to work
Use the :first-child
selector.
In your example...
$('div.alldivs div:first-child')
This will also match any first child descendents that meet the selection criteria.
While
:first
matches only a single element, the:first-child
selector can match more than one: one for each parent. This is equivalent to:nth-child(1)
.
For the first matched only, use the :first
selector.
Alternatively, Felix Kling suggested using the direct descendent selector to get only direct children...
$('div.alldivs > div:first-child')
Couple of points:
git stash
+ git stash drop
could be replaced with git reset --hard
... or, even shorter, add -f
to checkout
command:
git checkout -f -b $branch
That will discard any local changes, just as if git reset --hard
was used prior to checkout.
As for the main question:
instead of pulling in the last step, you could just merge the appropriate branch from the remote into your local branch: git merge $branch origin/$branch
, I believe it does not hit the remote. If that is the case, it removes the need for credensials and hence, addresses your biggest concern.
My fix was as simple as making sure the correct connection string was in ALL appsettings.json files, not just the default one.
If you are using C++11
, you should probably use stoi
because it can distinguish between an error and parsing "0"
.
try {
int number = std::stoi("1234abc");
} catch (std::exception const &e) {
// This could not be parsed into a number so an exception is thrown.
// atoi() would return 0, which is less helpful if it could be a valid value.
}
It should be noted that "1234abc" is implicitly converted from a char[]
to a std:string
before being passed to stoi()
.
This is a Python 101 type question,
It's a simple question but one where the answer is not so simple.
In python3, a "bytes" object represents a sequence of bytes, a "string" object represents a sequence of unicode code points.
To convert between from "bytes" to "string" and from "string" back to "bytes" you use the bytes.decode and string.encode functions. These functions take two parameters, an encoding and an error handling policy.
Sadly there are an awful lot of cases where sequences of bytes are used to represent text, but it is not necessarily well-defined what encoding is being used. Take for example filenames on unix-like systems, as far as the kernel is concerned they are a sequence of bytes with a handful of special values, on most modern distros most filenames will be UTF-8 but there is no gaurantee that all filenames will be.
If you want to write robust software then you need to think carefully about those parameters. You need to think carefully about what encoding the bytes are supposed to be in and how you will handle the case where they turn out not to be a valid sequence of bytes for the encoding you thought they should be in. Python defaults to UTF-8 and erroring out on any byte sequence that is not valid UTF-8.
print(bytesThing)
Python uses "repr" as a fallback conversion to string. repr attempts to produce python code that will recreate the object. In the case of a bytes object this means among other things escaping bytes outside the printable ascii range.
That DateTime format is actually ISO 8601 DateTime. JSON does not specify any particular format for dates/times. If you Google a bit, you will find plenty of implementations to parse it in Java.
If you are open to using something other than Java's built-in Date/Time/Calendar classes, I would also suggest Joda Time. They offer (among many things) a ISODateTimeFormat
to parse these kinds of strings.
Without seeing said object list, I believe you should be binding to the DataGrid's ItemsSource
property, not its DataContext
.
<DataGrid x:Name="Imported" VerticalAlignment="Top" ItemsSource="{Binding Source=list}" AutoGenerateColumns="False" CanUserResizeColumns="True">
<DataGrid.Columns>
<DataGridTextColumn Header="ID" Binding="{Binding ID}"/>
<DataGridTextColumn Header="Date" Binding="{Binding Date}"/>
</DataGrid.Columns>
</DataGrid>
(This assumes that the element [UserControl, etc.] that contains the DataGrid has its DataContext bound to an object that contains the list
collection. The DataGrid is derived from ItemsControl
, which relies on its ItemsSource
property to define the collection it binds its rows to. Hence, if list
isn't a property of an object bound to your control's DataContext, you might need to set both DataContext={Binding list}
and ItemsSource={Binding list}
on the DataGrid...)
Another option is replacing double quotes with single quotes if you don't mind whatever it is. But I don't mention this one:
<option value='"asd'>test</option>
I mention this one:
<option value="'asd">test</option>
In my case I used this solution.
To append to an array, just use the +=
operator.
$Target += $TargetObject
Also, you need to declare $Target = @()
before your loop because otherwise, it will empty the array every loop.
I wrote a plugin which enables me to navigate the file without moving the cursor position. It's based on folding the lines between your position and your target position and then jumping over the fold, or abort it and don't move at all.
It's also easy to fast-switch between the cursor on the first line, the last line and cursor in the middle by just clicking j, k or l when you are in the mode of the plugin.
I guess it would be a good fit here.
This is the solution . Its quite simple as a matter of fact
function binaries(num1){
var str = num1.toString(2)
return(console.log('The binary form of ' + num1 + ' is: ' + str))
}
binaries(3
)
/*
According to MDN, Number.prototype.toString() overrides
Object.prototype.toString() with the useful distinction that you can
pass in a single integer argument. This argument is an optional radix,
numbers 2 to 36 allowed.So in the example above, we’re passing in 2 to
get a string representation of the binary for the base 10 number 100,
i.e. 1100100.
*/
I figured this out, it was just a naming conflict issue: if you use TheBackground instead of Background it works as posted in the first example. The property Background was interfering with the Window property background.
Start by looking in Event Viewer, either under the System or the Application log.
In my case the problem was that no worker process could be started for the App Pool because its configuration file couldn't be read - I had included an extra '.' at the end of its name.
Out of all the combinations you tried, %ld
and %lu
are the only ones which are valid printf format specifiers at all. %lu
(long unsigned decimal), %lx
or %lX
(long hex with lowercase or uppercase letters), and %lo
(long octal) are the only valid format specifiers for a variable of type unsigned long (of course you can add field width, precision, etc modifiers between the %
and the l
).
Using the appropriate VerificationMode:
import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
verify(mockObject, atLeast(2)).someMethod("was called at least twice");
verify(mockObject, times(3)).someMethod("was called exactly three times");
An inline-block covers the whole line (from left to right), so a margin left and/or right won't work here. What you need is a block, a block has borders on the left and the right so can be influenced by margins.
This is how it works for me:
#content {
display: block;
margin: 0 auto;
}
Have you tried the import text function.
I had the same issue on Windows XP when running an application built with a static version of Qt 5.7.0 (MSVC 2013).
Adding the following line to the project's .pro file solved it:
QMAKE_LFLAGS_WINDOWS = /SUBSYSTEM:WINDOWS,5.01
The contract is that if obj1.equals(obj2)
then obj1.hashCode() == obj2.hashCode()
, it is mainly for performance reasons, as maps are mainly using hashCode method to compare entries keys.
a simple answer is, at html
<select name="ukuran" id="idUkuran">
<option value="1000">pilih ukuran</option>
<option value="11">M</option>
<option value="12">L</option>
<option value="13">XL</option>
</select>
on jquery, call below function by button or whatever
$('#idUkuran').val(11).change();
it simple and 100% works, coz its taken from my work... :) hope its help..
Try this one-
<script>
(function($){
$(document).on('contextmenu', 'img', function() {
return false;
})
})(jQuery);
</script>

If you put together the answers so far, clean up and improve, you would arrive at this superior query:
UPDATE sales
SET status = 'ACTIVE'
WHERE (saleprice, saledate) IN (
SELECT saleprice, saledate
FROM sales
GROUP BY saleprice, saledate
HAVING count(*) = 1
);
Which is much faster than either of them. Nukes the performance of the currently accepted answer by factor 10 - 15 (in my tests on PostgreSQL 8.4 and 9.1).
But this is still far from optimal. Use a NOT EXISTS
(anti-)semi-join for even better performance. EXISTS
is standard SQL, has been around forever (at least since PostgreSQL 7.2, long before this question was asked) and fits the presented requirements perfectly:
UPDATE sales s
SET status = 'ACTIVE'
WHERE NOT EXISTS (
SELECT FROM sales s1 -- SELECT list can be empty for EXISTS
WHERE s.saleprice = s1.saleprice
AND s.saledate = s1.saledate
AND s.id <> s1.id -- except for row itself
)
AND s.status IS DISTINCT FROM 'ACTIVE'; -- avoid empty updates. see below
db<>fiddle here
Old SQL Fiddle
If you don't have a primary or unique key for the table (id
in the example), you can substitute with the system column ctid
for the purpose of this query (but not for some other purposes):
AND s1.ctid <> s.ctid
Every table should have a primary key. Add one if you didn't have one, yet. I suggest a serial
or an IDENTITY
column in Postgres 10+.
Related:
The subquery in the EXISTS
anti-semi-join can stop evaluating as soon as the first dupe is found (no point in looking further). For a base table with few duplicates this is only mildly more efficient. With lots of duplicates this becomes way more efficient.
For rows that already have status = 'ACTIVE'
this update would not change anything, but still insert a new row version at full cost (minor exceptions apply). Normally, you do not want this. Add another WHERE
condition like demonstrated above to avoid this and make it even faster:
If status
is defined NOT NULL
, you can simplify to:
AND status <> 'ACTIVE';
The data type of the column must support the <>
operator. Some types like json
don't. See:
This query (unlike the currently accepted answer by Joel) does not treat NULL values as equal. The following two rows for (saleprice, saledate)
would qualify as "distinct" (though looking identical to the human eye):
(123, NULL)
(123, NULL)
Also passes in a unique index and almost anywhere else, since NULL values do not compare equal according to the SQL standard. See:
OTOH, GROUP BY
, DISTINCT
or DISTINCT ON ()
treat NULL values as equal. Use an appropriate query style depending on what you want to achieve. You can still use this faster query with IS NOT DISTINCT FROM
instead of =
for any or all comparisons to make NULL compare equal. More:
If all columns being compared are defined NOT NULL
, there is no room for disagreement.

In Python, the Scipy library can be used to convert the 2-D NumPy matrix into a Sparse matrix. SciPy 2-D sparse matrix package for numeric data is scipy.sparse
The scipy.sparse package provides different Classes to create the following types of Sparse matrices from the 2-dimensional matrix:
CSR (Compressed Sparse Row) or CSC (Compressed Sparse Column) formats support efficient access and matrix operations.
Example code to Convert Numpy matrix into Compressed Sparse Column(CSC) matrix & Compressed Sparse Row (CSR) matrix using Scipy classes:
import sys # Return the size of an object in bytes
import numpy as np # To create 2 dimentional matrix
from scipy.sparse import csr_matrix, csc_matrix
# csr_matrix: used to create compressed sparse row matrix from Matrix
# csc_matrix: used to create compressed sparse column matrix from Matrix
create a 2-D Numpy matrix
A = np.array([[1, 0, 0, 0, 0, 0],\
[0, 0, 2, 0, 0, 1],\
[0, 0, 0, 2, 0, 0]])
print("Dense matrix representation: \n", A)
print("Memory utilised (bytes): ", sys.getsizeof(A))
print("Type of the object", type(A))
Print the matrix & other details:
Dense matrix representation:
[[1 0 0 0 0 0]
[0 0 2 0 0 1]
[0 0 0 2 0 0]]
Memory utilised (bytes): 184
Type of the object <class 'numpy.ndarray'>
Converting Matrix A to the Compressed sparse row matrix representation using csr_matrix Class:
S = csr_matrix(A)
print("Sparse 'row' matrix: \n",S)
print("Memory utilised (bytes): ", sys.getsizeof(S))
print("Type of the object", type(S))
The output of print statements:
Sparse 'row' matrix:
(0, 0) 1
(1, 2) 2
(1, 5) 1
(2, 3) 2
Memory utilised (bytes): 56
Type of the object: <class 'scipy.sparse.csr.csc_matrix'>
Converting Matrix A to Compressed Sparse Column matrix representation using csc_matrix Class:
S = csc_matrix(A)
print("Sparse 'column' matrix: \n",S)
print("Memory utilised (bytes): ", sys.getsizeof(S))
print("Type of the object", type(S))
The output of print statements:
Sparse 'column' matrix:
(0, 0) 1
(1, 2) 2
(2, 3) 2
(1, 5) 1
Memory utilised (bytes): 56
Type of the object: <class 'scipy.sparse.csc.csc_matrix'>
As it can be seen the size of the compressed matrices is 56 bytes and the original matrix size is 184 bytes.

I am trying to do something similar to this. As commented above, I think you would want to build a new image with a custom Dockerfile (using the image you pulled as a base image), ADD
your certificate, then RUN update-ca-certificates
. This way you will have a consistent state each time you start a container from this new image.
# Dockerfile
FROM some-base-image:0.1
ADD you_certificate.crt:/container/cert/path
RUN update-ca-certificates
Let's say a docker build
against that Dockerfile produced IMAGE_ID. On the next docker run -d [any other options] IMAGE_ID
, the container started by that command will have your certificate info. Simple and reproducible.
I think that what you are stating as the "difference" is actually a consequence of the real difference.
The actual difference is the target of the code written. Who is going to run this code.
A scripting language is used to write code that is going to target a software system. It's going to automate operations on that software system. The script is going to be a sequence of instructions to the target software system.
A programming language targets the computing system, which can be a real or virtual machine. The instructions are executed by the machine.
Of course, a real machine understands only binary code so you need to compile the code of a programming language. But this is a consequence of targeting a machine instead of a program.
In the other hand, the target software system of an script may compile the code or interpret it. Is up to the software system.
If we say that the real difference is whether it is compiled or not, then we have a problem because when Javascript runs in V8 is compiled and when it runs in Rhino is not.
It gets more confusing since scripting languages have evolved to become very powerful. So they are not limited to create small scripts to automate operations on another software system, you can create any rich applications with them.
Python code targets an interpreter so we can say that it "scripts" operations on that interpreter. But when you write Python code you don't see it as scripting an interpreter, you see it as creating an application. The interpreter is just there to code at a higher level among other things. So for me Python is more a programming language than an scripting language.
Setting the CurrentCell
and then calling BeginEdit(true)
works well for me.
The following code shows an eventHandler for the KeyDown
event that sets a cell to be editable.
My example only implements one of the required key press overrides but in theory the others should work the same. (and I'm always setting the [0][0] cell to be editable but any other cell should work)
private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Tab && dataGridView1.CurrentCell.ColumnIndex == 1)
{
e.Handled = true;
DataGridViewCell cell = dataGridView1.Rows[0].Cells[0];
dataGridView1.CurrentCell = cell;
dataGridView1.BeginEdit(true);
}
}
If you haven't found it previously, the DataGridView FAQ is a great resource, written by the program manager for the DataGridView control, which covers most of what you could want to do with the control.
As an addendum to @xmechanix's answer, I noticed through writing the contents to a file:
echo | set /p dummyName=Hello World > somefile.txt
That this will add an extra space at the end of the printed string, which can be inconvenient, specially since we're trying to avoid adding a new line (another whitespace character) to the end of the string.
Fortunately, quoting the string to be printed, i.e. using:
echo | set /p dummyName="Hello World" > somefile.txt
Will print the string without any newline or space character at the end.
database user does not have the permission to do select query.
you can grant the permission to the user if you have root access to mysql
http://dev.mysql.com/doc/refman/5.1/en/grant.html
Your second query is on different database on different table.
String newSQL = "Select `Strike`,`LongShort`,`Current`,`TPLevel`,`SLLevel` from `json`.`tbl_Position` where `TradeID` = '" + i + "'";
And the user you are connecting with does not have permission to access data from this database or this particular table.
Have you consider this thing?
Windows solution: Assuming all files contained in sub-directory 'src', and you want to compile them to 'bin'.
for /r src %i in (*.java) do javac %i -sourcepath src -d bin
If src contains a .java file immediately below it then this is faster
javac src\\*.java -d bin
If you're sure that this object is an Integer
:
int i = (Integer) object;
Or, starting from Java 7, you can equivalently write:
int i = (int) object;
Beware, it can throw a ClassCastException
if your object isn't an Integer
and a NullPointerException
if your object is null
.
This way you assume that your Object is an Integer (the wrapped int) and you unbox it into an int.
int
is a primitive so it can't be stored as an Object
, the only way is to have an int
considered/boxed as an Integer
then stored as an Object
.
If your object is a String
, then you can use the Integer.valueOf()
method to convert it into a simple int :
int i = Integer.valueOf((String) object);
It can throw a NumberFormatException
if your object isn't really a String
with an integer as content.

All the three are access modifiers and keywords which are used in a class. Anything declared in public can be used by any object within the class or outside the class,variables in private can only be used by the objects within the class and could not be changed through direct access(as it can change through functions like friend function).Anything defined under protected section can be used by the class and their just derived class.
Try the following:

Iif you want a particular <canvas id="canvasID">
to be always transparent you just have to set
#canvasID{
opacity:0.5;
}
Instead, if you want some particular elements inside the canvas area to be transparent, you have to set transparency when you draw, i.e.
context.fillStyle = "rgba(0, 0, 200, 0.5)";
You could do:
if [[ " ${arr[*]} " == *" d "* ]]; then
echo "arr contains d"
fi
This will give false positives for example if you look for "a b" -- that substring is in the joined string but not as an array element. This dilemma will occur for whatever delimiter you choose.
The safest way is to loop over the array until you find the element:
array_contains () {
local seeking=$1; shift
local in=1
for element; do
if [[ $element == "$seeking" ]]; then
in=0
break
fi
done
return $in
}
arr=(a b c "d e" f g)
array_contains "a b" "${arr[@]}" && echo yes || echo no # no
array_contains "d e" "${arr[@]}" && echo yes || echo no # yes
Here's a "cleaner" version where you just pass the array name, not all its elements
array_contains2 () {
local array="$1[@]"
local seeking=$2
local in=1
for element in "${!array}"; do
if [[ $element == "$seeking" ]]; then
in=0
break
fi
done
return $in
}
array_contains2 arr "a b" && echo yes || echo no # no
array_contains2 arr "d e" && echo yes || echo no # yes
For associative arrays, there's a very tidy way to test if the array contains a given key: The -v
operator
$ declare -A arr=( [foo]=bar [baz]=qux )
$ [[ -v arr[foo] ]] && echo yes || echo no
yes
$ [[ -v arr[bar] ]] && echo yes || echo no
no

There's always Cygwin.
Could append a new stylesheet to head within $routeProvider
. For simplicity am using a string but could create new link element also, or create a service for stylesheets
/* check if already exists first - note ID used on link element*/
/* could also track within scope object*/
if( !angular.element('link#myViewName').length){
angular.element('head').append('<link id="myViewName" href="myViewName.css" rel="stylesheet">');
}
Biggest benefit of prelaoding in page is any background images will already exist, and less lieklyhood of FOUC
In case of a number you can try to convert to string:
var stringValue = str.toString();
return stringValue.replace(/^\s+|\s+$/g,'');
Just my two cents. If you are using Bootstrap 3 then I would just add an extra style into your own site's stylesheet which controls the text-left
style of the control-label
.
If you were to add text-left
to the label, by default there is another style which overrides this .form-horizontal .control-label
. So if you add:
.form-horizontal .control-label.text-left{
text-align: left;
}
Then the built in text-left
style is applied to the label correctly.
You don't need (shouldn't use) a function as far as I can tell. The stored procedure will return tabular data from any SELECT statements you include that return tabular data.
A stored proc does not use RETURN statements.
CREATE PROCEDURE name
AS
SELECT stuff INTO #temptbl1
.......
SELECT columns FROM #temptbln
SELECT D.DeptID, E.EmpName, E.Salary
FROM Employee E
INNER JOIN Department D ON D.DeptId = E.DeptId
WHERE E.Salary IN (SELECT MAX(Salary) FROM Employee);
