This should work for you:
$('.SeeMore2').click(function(){
var $this = $(this);
$this.toggleClass('SeeMore2');
if($this.hasClass('SeeMore2')){
$this.text('See More');
} else {
$this.text('See Less');
}
});
In your example you should mock Listener item and use Mockito.verify to check interactions with it
As already mentioned, git commit --amend
is the way to overwrite the last commit. One note: if you would like to also overwrite the files, the command would be
git commit -a --amend -m "My new commit message"

Look into using the ToString()
method with a specified format.
If you use the solution from @jorge and find that everything is on the same line, make sure you enclose the variable in quotes:
echo $__usage
will print everything on one line whereas
echo "$__usage"
will retain the newlines.
.list-inline class in bootstrap is a Inline Unordered List.
If you want to create a horizontal menu using ordered or unordered list you need to place all list items in a single line i.e. side by side. You can do this by simply applying the class
<div class="list-inline">
<a href="#" class="list-inline-item">First item</a>
<a href="#" class="list-inline-item">Secound item</a>
<a href="#" class="list-inline-item">Third item</a>

Assuming the column is set to support NULL as a value:
UPDATE YOUR_TABLE
SET column = NULL
Be aware of the database NULL handling - by default in SQL Server, NULL is an INT. So if the column is a different data type you need to CAST/CONVERT NULL to the proper data type:
UPDATE YOUR_TABLE
SET column = CAST(NULL AS DATETIME)
...assuming column
is a DATETIME data type in the example above.
You might find a use for the methods
method which returns an array of methods for an object. It's not the same as print_r
, but still useful at times.

Context
provides information about the Actvity
or Application
to newly created components.
Relevant Context
should be provided to newly created components (whether application context or activity context)
Since Activity
is a subclass of Context
, one can use this
to get that activity's context
This is probably not a direct answer to what you're asking, but when I need to transfer files over a SSH session I use WinSCP, which is an excellent file transfer program over SCP or SFTP. Of course this assumes you're on Windows.
EDIT 2015-06-27: Minimum is actually 8, including country code. My bad.

The minimum phone number that I use is 10 digits. International users should always be putting their country code, and as far as I know there are no countries with fewer than ten digits if you count country code.

You can use the below expression:

Invalid entries: all negative real numbers and 0 and 0.0
With question 3, this article states that RESTful Services are appropiate in this scenarios:
While SOAP is the way to go when:
While not as pretty as querySelectorAll
(which has a litany of issues), here's a very flexible function that recurses the DOM and should work in most browsers (old and new). As long as the browser supports your condition (ie: data attributes), you should be able to retrieve the element.
To the curious: Don't bother testing this vs. QSA on jsPerf. Browsers like Opera 11 will cache the query and skew the results.
Code:
function recurseDOM(start, whitelist)
{
/*
* @start: Node - Specifies point of entry for recursion
* @whitelist: Object - Specifies permitted nodeTypes to collect
*/
var i = 0,
startIsNode = !!start && !!start.nodeType,
startHasChildNodes = !!start.childNodes && !!start.childNodes.length,
nodes, node, nodeHasChildNodes;
if(startIsNode && startHasChildNodes)
{
nodes = start.childNodes;
for(i;i<nodes.length;i++)
{
node = nodes[i];
nodeHasChildNodes = !!node.childNodes && !!node.childNodes.length;
if(!whitelist || whitelist[node.nodeType])
{
//condition here
if(!!node.dataset && !!node.dataset.foo)
{
//handle results here
}
if(nodeHasChildNodes)
{
recurseDOM(node, whitelist);
}
}
node = null;
nodeHasChildNodes = null;
}
}
}
You can then initiate it with the following:
recurseDOM(document.body, {"1": 1});
for speed, or just recurseDOM(document.body);

I use different predefined colors like so:
theme = {
whateverFlashColor: '#ffffaa',
whateverElseFlashColor: '#bbffaa',
whateverElseThenFlashColor: '#ffffff',
};
and use them like this
$('#element').effect("highlight", {color:theme.whateverFlashColor}, 1000);
easy :)

I asked the same question of the lodash maintainers a while back and they replied by mentioning the !=
operator can be used here:
if(newVal != null) {
// newVal is defined
}
This uses JavaScript's type coercion to check the value for undefined
or null
.
If you are using JSHint to lint your code, add the following comment blocks to tell it that you know what you are doing - most of the time !=
is considered bad.
/* jshint -W116 */
if(newVal != null) {
/* jshint +W116 */
// newVal is defined
}
Check your Pattern (DD-MMM-YYYY) and the input for the parse("29-11-2018") method. Input to the parse method should follow : DD-MMM-YYYY i,e. 21-AUG-2019
In My Code:
String pattern = "DD-MMM-YYYY";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(pattern);
try {
startDate = simpleDateFormat.parse("29-11-2018");// here no pattern match
endDate = simpleDateFormat.parse("28-AUG-2019");// Ok
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();

One way is to add the item(s) to be deleted to a new list. Then go through and delete those items.
I was unable to use the JSONConvert method suggested by xhafan
In .Net 4.5 even after adding the "System.Web.Extensions" assembly reference I was still unable to access the JSONConvert.
However, once you add the reference you can get the same string print out using:
JavaScriptSerializer js = new JavaScriptSerializer();
string jsonstring = js.Serialize(yourClassObject);
ActivityManager
If you only want to know the application containing the current activity, you can do so using ActivityManager
. The technique you can use depends on the version of Android:
ActivityManager.getRunningTasks
(example)ActivityManager.getRunningAppProcesses
(example)ActivityManager.RunningAppProcessInfo.processState
public class CurrentApplicationPackageRetriever {
private final Context context;
public CurrentApplicationPackageRetriever(Context context) {
this.context = context;
}
public String get() {
if (Build.VERSION.SDK_INT < 21)
return getPreLollipop();
else
return getLollipop();
}
private String getPreLollipop() {
@SuppressWarnings("deprecation")
List<ActivityManager.RunningTaskInfo> tasks =
activityManager().getRunningTasks(1);
ActivityManager.RunningTaskInfo currentTask = tasks.get(0);
ComponentName currentActivity = currentTask.topActivity;
return currentActivity.getPackageName();
}
private String getLollipop() {
final int PROCESS_STATE_TOP = 2;
try {
Field processStateField = ActivityManager.RunningAppProcessInfo.class.getDeclaredField("processState");
List<ActivityManager.RunningAppProcessInfo> processes =
activityManager().getRunningAppProcesses();
for (ActivityManager.RunningAppProcessInfo process : processes) {
if (
// Filters out most non-activity processes
process.importance <= ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND
&&
// Filters out processes that are just being
// _used_ by the process with the activity
process.importanceReasonCode == 0
) {
int state = processStateField.getInt(process);
if (state == PROCESS_STATE_TOP) {
String[] processNameParts = process.processName.split(":");
String packageName = processNameParts[0];
/*
If multiple candidate processes can get here,
it's most likely that apps are being switched.
The first one provided by the OS seems to be
the one being switched to, so we stop here.
*/
return packageName;
}
}
}
} catch (NoSuchFieldException | IllegalAccessException e) {
throw new RuntimeException(e);
}
return null;
}
private ActivityManager activityManager() {
return (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
}
}
Add the GET_TASKS
permission to AndroidManifest.xml
:
<!--suppress DeprecatedClassUsageInspection -->
<uses-permission android:name="android.permission.GET_TASKS" />
you can also use this if you know the name of the primary key
SELECT
MAX(primary_key_name) + 1
FROM
TABLE_NAME
As user @aaracrr pointed out in a comment on another answer probably the best answer is to re-require the package with the same version constraint.
ie.
composer require vendor/package
or specifying a version constraint
composer require vendor/package:^1.0.0
Using dialog methods:
$('.selectorUsedToCreateTheDialog').dialog('option', 'title', 'My New title');
Or directly, hacky though:
$("span.ui-dialog-title").text('My New Title');
For future reference, you can skip google with jQuery. The jQuery API will answer your questions most of the time. In this case, the Dialog API page. For the main library: http://api.jquery.com
The integer math solution that Ian provided is nice, but suffers from an integer overflow bug. Assuming the variables are all int
, the solution could be rewritten to use long
math and avoid the bug:
int pageCount = (-1L + records + recordsPerPage) / recordsPerPage;
If records
is a long
, the bug remains. The modulus solution does not have the bug.
You Could also use this.. it works assuming 'yourimage.jpg' is in your public folder.

If you are using SQL Server 2012, 2014 or newer, use the Format Function instead:
select Format( decimalColumnName ,'FormatString','en-US' )
Review the Microsoft topic and .NET format syntax for how to define the format string.

select Format( MyDecimalColumn ,'N','en-US' )

From Wikipedia:
Applications implementing common services often use specifically reserved, well-known port numbers for receiving service requests from client hosts. This process is known as listening and involves the receipt of a request on the well-known port and reestablishing one-to-one server-client communications on another private port, so that other clients may also contact the well-known service port. The well-known ports are defined by convention overseen by the Internet Assigned Numbers Authority (IANA).
So as others mentioned, it's a convention.
If the newly used computer has different credentials running this command
git clone https://github.com/username/reponame.git
directly will not work. Git will attempt to use the stored credentials and will not prompt you for the username and the password. Since the credentials mismatch, git will output Repository not found
and the clone operation fails. The way I solved it was by deleting the old credentials, since I don't use them anymore, and ran the the above mentioned command again and entered the required username and password and cloned the private repo.
While most of the answers above are useful, in case you: 1) need it to support non-positive-integer values (e.g. floats or negative integers ;-)), and 2) aren't on Python 2.7 (which collections.Counter requires), and 3) prefer not to add the dependency of scipy (or even numpy) to your code, then a purely python 2.6 solution that is O(nlogn) (i.e., efficient) is just this:
from collections import defaultdict
a = [1,2,3,1,2,1,1,1,3,2,2,1]
d = defaultdict(int)
for i in a:
d[i] += 1
most_frequent = sorted(d.iteritems(), key=lambda x: x[1], reverse=True)[0]
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File (sdCard.getAbsolutePath() + "/dir1/dir2");
dir.mkdirs();
File file = new File(dir, "filename");
FileOutputStream f = new FileOutputStream(file);
...
Adding max-width: 100%;
to the img
tag works for me.
You could compare DOM elements. Remember that jQuery selectors return arrays which will never be equal in the sense of reference equality.
Assuming:
<div id="a" class="a"></div>
this:
$('div.a')[0] == $('div#a')[0]
returns true.
There is no "right way". If you want a universal (but suboptimal) solution you can use a boost::lexical cast
.
A common solution for C++ is to use std::ostream
and << operator
. You can use a stringstream
and stringstream::str()
method for conversion to string.
If you really require a fast mechanism (remember the 20/80 rule) you can look for a "dedicated" solution like C++ String Toolkit Library

The differences are listed in the Javadoc for ListIterator

That depends. If that definition is global (outside any function) then num
will be initialized to zero. If it's local (inside a function) then its value is indeterminate. In theory, even attempting to read the value has undefined behavior -- C allows for the possibility of bits that don't contribute to the value, but have to be set in specific ways for you to even get defined results from reading the variable.
I'm working on an app and face issue of killing my service by on app kill. I researched on google and found that I have to make it foreground. following is the code:
public class UpdateLocationAndPrayerTimes extends Service {
Context context;
@Override
public void onCreate() {
super.onCreate();
context = this;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
StartForground();
return START_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
private void StartForground() {
LocationChangeDetector locationChangeDetector = new LocationChangeDetector(context);
locationChangeDetector.getLatAndLong();
Notification notification = new NotificationCompat.Builder(this)
.setOngoing(false)
.setSmallIcon(android.R.color.transparent)
//.setSmallIcon(R.drawable.picture)
.build();
startForeground(101, notification);
}
}
hops that it may helps!!!!
add_header
works as well with proxy_pass
as without. I just today set up a configuration where I've used exactly that directive. I have to admit though that I've struggled as well setting this up without exactly recalling the reason, though.
Right now I have a working configuration and it contains the following (among others):
server {
server_name .myserver.com
location / {
proxy_pass http://mybackend;
add_header X-Upstream $upstream_addr;
}
}
Before nginx 1.7.5
add_header worked only on successful responses, in contrast to the HttpHeadersMoreModule mentioned by Sebastian Goodman in his answer.
Since nginx 1.7.5
you can use the keyword always
to include custom headers even in error responses. For example:
add_header X-Upstream $upstream_addr always;
Limitation: You cannot override the server
header value using add_header
.
For the sake of (over)complexity I'll add my overloaded version which replaces the last 3 characters with an ellipsis in respect with the maxLength parameter.
public static string Truncate(this string value, int maxLength, bool replaceTruncatedCharWithEllipsis = false)
{
if (replaceTruncatedCharWithEllipsis && maxLength <= 3)
throw new ArgumentOutOfRangeException("maxLength",
"maxLength should be greater than three when replacing with an ellipsis.");
if (String.IsNullOrWhiteSpace(value))
return String.Empty;
if (replaceTruncatedCharWithEllipsis &&
value.Length > maxLength)
{
return value.Substring(0, maxLength - 3) + "...";
}
return value.Substring(0, Math.Min(value.Length, maxLength));
}
The problem with String.Join is that you are not handling the case of a comma already existing in the value. When a comma exists then you surround the value in Quotes and replace all existing Quotes with double Quotes.
String.Join(",",{"this value has a , in it","This one doesn't", "This one , does"});
See CSV Module
When you run your form and you want showing text in textbox is clear so you put the code : -
textBox1.text = String.Empty;
Where textBox1 is your textbox name.

For modern browsers, you may try the following approach:
https://developer.mozilla.org/en/HTTP_access_control
In short, you need to add the following into the SERVER
response header (the following allows access from foo.example
):
Access-Control-Allow-Origin: http://foo.example
Access-Control-Allow-Methods: POST, GET, OPTIONS
Access-Control-Allow-Headers: X-PINGOTHER
Access-Control-Max-Age: 1728000
Note that the X-PINGOTHER
is the custom header that is inserted by JavaScript, and should differ from site to site.
If you want any site access your server in Ajax, use *
instead.
Edit:
When I first answered the question by 2009, I actually hit the same problem, and I worked around it using the server side config.
There was no plugin on FF or Chrome by then.
However, now we do have alternatives using the browser side plugin, please check the answer of tsds
It is a little difficult to answer your specific question without a full, reproducible example. However something like this should work:
#Turn your 'treatment' column into a character vector
data$Treatment <- as.character(data$Treatment)
#Then turn it back into a factor with the levels in the correct order
data$Treatment <- factor(data$Treatment, levels=unique(data$Treatment))
In this example, the order of the factor will be the same as in the data.csv
file.
If you prefer a different order, you can order them by hand:
data$Treatment <- factor(data$Treatment, levels=c("Y", "X", "Z"))
However this is dangerous if you have a lot of levels: if you get any of them wrong, that will cause problems.
Not sure I completely understand the question but:
$(":button.brown").click(function() {
$(":button.brown.selected").removeClass("selected");
$(this).addClass("selected");
});
seems to be along the lines of what you want.
I would certainly recommend using classes instead of directly setting CSS, which is problematic for several reasons (eg removing styles is non-trivial, removing classes is easy) but if you do want to go that way:
$("...").css("background", "brown");
But when you want to reverse that change, what do you set it to?
You could use ng-init in an outer div:
<div ng-init="param='value';">
<div ng-controller="BasketController" >
<label>param: {{value}}</label>
</div>
</div>
The parameter will then be available in your controller's scope:
function BasketController($scope) {
console.log($scope.param);
}
If you have zsh installed add alias to .zshrc file in home directory as well.
This can also happen if your file permissions get changed somehow. Removing the lock file didn't help, and we were getting errors in the log file like:
2016-01-20T09:14:58.210-0800 [initandlisten] warning couldn't write to / rename file /var/lib/mongodb/journal/prealloc.0: couldn't open file /var/lib/mongodb/journal/prealloc.0 for writing errno:13 Permission denied

-rwxr-xr-x 1 mongodb nogroup 0 Jan 20 09:14 mongod.lock
To fix:
# chown -R mongodb:mongodb /var/lib/mongodb
Remove the lock file if it's still there:
# rm /var/lib/mongodb/mongod.lock
Start mongodb
# service mongodb start
Tail the log and you should see at the end of it:

what you need exactly is
def fun():
raise Exception()
f = lambda x:print x if x==2 else fun()
now call the function the way you need
f(2)
f(3)
You can use
git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch <file/dir>' HEAD
This will delete everything in the history of that file. The problem is that the file is present in the history.
This command changes the hashes of your commits which can be a real problem, especially on shared repositories. It should not be performed without understanding the consequences.

Thinking more about it, I would like to throw out tuples as a more general-purpose way of dealing with this problem. While tuples are not native to Java, I use Javatuples to provide me the same functionality which would exist in other languages. An example of how to deal with the question asked is
Map<Pair<Integer, String>, String> arr = new HashMap<Pair<Integer, String>, String>();
Pair p1 = new Pair(0, "name");
arr.put(p1, "demo");
I like this approach because it can be extended to triples and other higher ordered groupings with api provided classes and methods.
I was trying to do the exact same thing, open a text file (a CSV for Pandas actually). Don't want to make a copy of it, just want to open it. The form-WTF has a nice file browser, but then it opens the file and makes a temporary file, which it presents as a memory stream. With a little work under the hood,
form = UploadForm()
if form.validate_on_submit():
filename = secure_filename(form.fileContents.data.filename)
filestream = form.fileContents.data
filestream.seek(0)
ef = pd.read_csv( filestream )
sr = pd.DataFrame(ef)
return render_template('dataframe.html',tables=[sr.to_html(justify='center, classes='table table-bordered table-hover')],titles = [filename], form=form)

"fb://page/
does not work with newer versions of the FB app. You should use fb://facewebmodal/f?href=
for newer versions.
This is a full fledged working code currently live in one of my apps:
public static String FACEBOOK_URL = "https://www.facebook.com/YourPageName";
public static String FACEBOOK_PAGE_ID = "YourPageName";
//method to get the right URL to use in the intent
public String getFacebookPageURL(Context context) {
PackageManager packageManager = context.getPackageManager();
try {
int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;
if (versionCode >= 3002850) { //newer versions of fb app
return "fb://facewebmodal/f?href=" + FACEBOOK_URL;
} else { //older versions of fb app
return "fb://page/" + FACEBOOK_PAGE_ID;
}
} catch (PackageManager.NameNotFoundException e) {
return FACEBOOK_URL; //normal web url
}
}
This method will return the correct url for app if installed or web url if app is not installed.
Then start an intent as follows:
Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
String facebookUrl = getFacebookPageURL(this);
facebookIntent.setData(Uri.parse(facebookUrl));
startActivity(facebookIntent);
That's all you need.
This can also happen if you've been working on your scripts and functions and have been moving them around (i.e. changed the location of the definition) which could have accidentally created a looping reference.
You may find that the situation is solved if you just reset the iPython kernal to clear any old assignments:

Well the answer was sitting right in front of me the whole time.
In SQL Server Management Studio 2008 there is a Debug button in the toolbar. Set a break point in a query window to step through.
I dismissed this functionality at the beginning because I didn't think of stepping INTO the stored procedure, which you can do with ease.
SSMS basically does what FinnNK mentioned with the MSDN walkthrough but automatically.
So easy! Thanks for your help FinnNK.
Edit: I should add a step in there to find the stored procedure call with parameters I used SQL Profiler on my database.
SELECT 'Y' REC_EXISTS
FROM SALES
WHERE SALES_TYPE = 'Accessories'
The result will either be 'Y' or NULL. Simply test against 'Y'
The number in parentheses in a type declaration is display width, which is unrelated to the range of values that can be stored in a data type. Just because you can declare Int(20)
does not mean you can store values up to 10^20 in it:
[...] This optional display width may be used by applications to display integer values having a width less than the width specified for the column by left-padding them with spaces. ...
The display width does not constrain the range of values that can be stored in the column, nor the number of digits that are displayed for values having a width exceeding that specified for the column. For example, a column specified as SMALLINT(3) has the usual SMALLINT range of -32768 to 32767, and values outside the range allowed by three characters are displayed using more than three characters.
For a list of the maximum and minimum values that can be stored in each MySQL datatype, see here.
There is a CSS 'length value' of ch
.
This unit represents the width, or more precisely the advance measure, of the glyph '0' (zero, the Unicode character U+0030) in the element's font.
This may approximate what you are after.

I don't know the real reason but Maven pushes developers to install all libraries (custom too) into some maven repositories, so scope:system
is not well liked, A simple workaround is to use maven-install-plugin
follow the usage:
write your dependency in this way
<dependency>
<groupId>com.mylib</groupId>
<artifactId>mylib-core</artifactId>
<version>0.0.1</version>
</dependency>
then, add maven-install-plugin
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.5.2</version>
<executions>
<execution>
<id>install-external</id>

<packaging>jar</packaging>
<generatePom>true</generatePom>
</configuration>
<goals>
<goal>install-file</goal>
</goals>

pay attention to phase:clean
, to install your custom library into your repository, you have to run mvn clean
and then mvn install
This does in fact relate to the long standing issue at http://jira.mongodb.org/browse/SERVER-1243 where there are in fact a number of challenges to a clear syntax that supports "all cases" where mutiple array matches are found. There are in fact methods already in place that "aid" in solutions to this problem, such as Bulk Operations which have been implemented after this original post.
It is still not possible to update more than a single matched array element in a single update statement, so even with a "multi" update all you will ever be able to update is just one mathed element in the array for each document in that single statement.
The best possible solution at present is to find and loop all matched documents and process Bulk updates which will at least allow many operations to be sent in a single request with a singular response. You can optionally use .aggregate()
to reduce the array content returned in the search result to just those that match the conditions for the update selection:
db.collection.aggregate([
{ "$match": { "events.handled": 1 } },
{ "$project": {
"events": {
"$setDifference": [
{ "$map": {
"input": "$events",
"as": "event",
"in": {
"$cond": [
{ "$eq": [ "$$event.handled", 1 ] },
"$$el",
false
]
}
}},
[false]
]
}
}}
]).forEach(function(doc) {
doc.events.forEach(function(event) {
bulk.find({ "_id": doc._id, "events.handled": 1 }).updateOne({
"$set": { "events.$.handled": 0 }
});
count++;
if ( count % 1000 == 0 ) {
bulk.execute();
bulk = db.collection.initializeOrderedBulkOp();
}
});
});
if ( count % 1000 != 0 )
bulk.execute();
The .aggregate()
portion there will work when there is a "unique" identifier for the array or all content for each element forms a "unique" element itself. This is due to the "set" operator in $setDifference
used to filter any false
values returned from the $map
operation used to process the array for matches.
If your array content does not have unique elements you can try an alternate approach with $redact
:
db.collection.aggregate([
{ "$match": { "events.handled": 1 } },
{ "$redact": {
"$cond": {
"if": {
"$eq": [ { "$ifNull": [ "$handled", 1 ] }, 1 ]
},
"then": "$$DESCEND",
"else": "$$PRUNE"
}
}}
])
Where it's limitation is that if "handled" was in fact a field meant to be present at other document levels then you are likely going to get unexepected results, but is fine where that field appears only in one document position and is an equality match.
Future releases ( post 3.1 MongoDB ) as of writing will have a $filter
operation that is simpler:
db.collection.aggregate([
{ "$match": { "events.handled": 1 } },
{ "$project": {
"events": {
"$filter": {
"input": "$events",
"as": "event",
"cond": { "$eq": [ "$$event.handled", 1 ] }
}
}
}}
])
And all releases that support .aggregate()
can use the following approach with $unwind
, but the usage of that operator makes it the least efficient approach due to the array expansion in the pipeline:
db.collection.aggregate([
{ "$match": { "events.handled": 1 } },
{ "$unwind": "$events" },
{ "$match": { "events.handled": 1 } },
{ "$group": {
"_id": "$_id",
"events": { "$push": "$events" }
}}
])
In all cases where the MongoDB version supports a "cursor" from aggregate output, then this is just a matter of choosing an approach and iterating the results with the same block of code shown to process the Bulk update statements. Bulk Operations and "cursors" from aggregate output are introduced in the same version ( MongoDB 2.6 ) and therefore usually work hand in hand for processing.
In even earlier versions then it is probably best to just use .find()
to return the cursor, and filter out the execution of statements to just the number of times the array element is matched for the .update()
iterations:
db.collection.find({ "events.handled": 1 }).forEach(function(doc){
doc.events.filter(function(event){ return event.handled == 1 }).forEach(function(event){
db.collection.update({ "_id": doc._id },{ "$set": { "events.$.handled": 0 }});
});
});
If you are aboslutely determined to do "multi" updates or deem that to be ultimately more efficient than processing multiple updates for each matched document, then you can always determine the maximum number of possible array matches and just execute a "multi" update that many times, until basically there are no more documents to update.
A valid approach for MongoDB 2.4 and 2.2 versions could also use .aggregate()
to find this value:
var result = db.collection.aggregate([
{ "$match": { "events.handled": 1 } },
{ "$unwind": "$events" },
{ "$match": { "events.handled": 1 } },
{ "$group": {
"_id": "$_id",
"count": { "$sum": 1 }
}},
{ "$group": {
"_id": null,
"count": { "$max": "$count" }
}}
]);
var max = result.result[0].count;
while ( max-- ) {
db.collection.update({ "events.handled": 1},{ "$set": { "events.$.handled": 0 }},{ "multi": true })
}
Whatever the case, there are certain things you do not want to do within the update:
Do not "one shot" update the array: Where if you think it might be more efficient to update the whole array content in code and then just $set
the whole array in each document. This might seem faster to process, but there is no guarantee that the array content has not changed since it was read and the update is performed. Though $set
is still an atomic operator, it will only update the array with what it "thinks" is the correct data, and thus is likely to overwrite any changes occurring between read and write.
Do not calculate index values to update: Where similar to the "one shot" approach you just work out that position 0
and position 2
( and so on ) are the elements to update and code these in with and eventual statement like:
{ "$set": {
"events.0.handled": 0,
"events.2.handled": 0
}}
Again the problem here is the "presumption" that those index values found when the document was read are the same index values in th array at the time of update. If new items are added to the array in a way that changes the order then those positions are not longer valid and the wrong items are in fact updated.
So until there is a reasonable syntax determined for allowing multiple matched array elements to be processed in single update statement then the basic approach is to either update each matched array element in an indvidual statement ( ideally in Bulk ) or essentially work out the maximum array elements to update or keep updating until no more modified results are returned. At any rate, you should "always" be processing positional $
updates on the matched array element, even if that is only updating one element per statement.
Bulk Operations are in fact the "generalized" solution to processing any operations that work out to be "multiple operations", and since there are more applications for this than merely updating mutiple array elements with the same value, then it has of course been implemented already, and it is presently the best approach to solve this problem.
I use varargs frequently for outputting to the logs for purposes of debugging.
Pretty much every class in my app has a method debugPrint():
private void debugPrint(Object... msg) {
for (Object item : msg) System.out.print(item);
System.out.println();
}
Then, within methods of the class, I have calls like the following:
debugPrint("for assignment ", hwId, ", student ", studentId, ", question ",
serialNo, ", the grade is ", grade);
When I'm satisfied that my code is working, I comment out the code in the debugPrint() method so that the logs will not contain too much extraneous and unwanted information, but I can leave the individual calls to debugPrint() uncommented. Later, if I find a bug, I just uncomment the debugPrint() code, and all my calls to debugPrint() are reactivated.
Of course, I could just as easily eschew varargs and do the following instead:
private void debugPrint(String msg) {
System.out.println(msg);
}
debugPrint("for assignment " + hwId + ", student " + studentId + ", question "
+ serialNo + ", the grade is " + grade);
However, in this case, when I comment out the debugPrint() code, the server still has to go through the trouble of concatenating all the variables in every call to debugPrint(), even though nothing is done with the resulting string. If I use varargs, however, the server only has to put them in an array before it realizes that it doesn't need them. Lots of time is saved.
You can do it with Array.prototype.filter()
,
var data = { records : [{ "empid": 1, "fname": "X", "lname": "Y" }, { "empid": 2, "fname": "A", "lname": "Y" }, { "empid": 3, "fname": "B", "lname": "Y" }, { "empid": 4, "fname": "C", "lname": "Y" }, { "empid": 5, "fname": "C", "lname": "Y" }] }
var empIds = [1,4,5]
var filteredArray = data.records.filter(function(itm){
return empIds.indexOf(itm.empid) > -1;
});
filteredArray = { records : filteredArray };
If? the ?callBack
? returns a ?true
? value, then the ?itm
? passed to that particular callBack
will be filtered out. You can read more about it here.??????
In order to sync
multiple models along with custom pivot data, you need this:
$user->roles()->sync([
1 => ['expires' => true],
2 => ['expires' => false],
...
]);
Ie.
sync([
related_id => ['pivot_field' => value],
...
]);
edit
Answering the comment:
$speakers = (array) Input::get('speakers'); // related ids
$pivotData = array_fill(0, count($speakers), ['is_speaker' => true]);
$syncData = array_combine($speakers, $pivotData);
$user->roles()->sync($syncData);

What about
import operator
auths = Author.objects.order_by('-score')[:30]
ordered = sorted(auths, key=operator.attrgetter('last_name'))
In Django 1.4 and newer you can order by providing multiple fields.
Reference: https://docs.djangoproject.com/en/dev/ref/models/querysets/#order-by
order_by(*fields)
By default, results returned by a QuerySet
are ordered by the ordering tuple given by the ordering
option in the model’s Meta. You can override this on a per-QuerySet basis by using the order_by
method.
Example:
ordered_authors = Author.objects.order_by('-score', 'last_name')[:30]
The result above will be ordered by score
descending, then by last_name
ascending. The negative sign in front of "-score"
indicates descending order. Ascending order is implied.
Updated for Swift 3 and above:
//1. Create the alert controller.
let alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .alert)
//2. Add the text field. You can configure it however you need.
alert.addTextField { (textField) in
textField.text = "Some default text"
}
// 3. Grab the value from the text field, and print it when the user clicks OK.
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { [weak alert] (_) in
let textField = alert.textFields![0] // Force unwrapping because we know it exists.
print("Text field: \(textField.text)")
}))
// 4. Present the alert.
self.present(alert, animated: true, completion: nil)
Swift 2.x
Assuming you want an action alert on iOS:
//1. Create the alert controller.
var alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .Alert)
//2. Add the text field. You can configure it however you need.
alert.addTextFieldWithConfigurationHandler({ (textField) -> Void in
textField.text = "Some default text."
})
//3. Grab the value from the text field, and print it when the user clicks OK.
alert.addAction(UIAlertAction(title: "OK", style: .Default, handler: { [weak alert] (action) -> Void in
let textField = alert.textFields![0] as UITextField
println("Text field: \(textField.text)")
}))
// 4. Present the alert.
self.presentViewController(alert, animated: true, completion: nil)
I know it's an old question, but what I did is not mentioned here.
For me the following worked.
DECLARE @info NVARCHAR(MAX)
--SET @info to something big
PRINT CAST(@info AS NTEXT)
Maybe you could take a look at JFileChooser, which allow you to use native dialogs in one line of code.
You can set Execution time-out in seconds.
You get the cursor position by calling GetCursorPos
.
POINT p;
if (GetCursorPos(&p))
{
//cursor position now in p.x and p.y
}
This returns the cursor position relative to screen coordinates. Call ScreenToClient
to map to window coordinates.
if (ScreenToClient(hwnd, &p))
{
//p.x and p.y are now relative to hwnd's client area
}
You hide and show the cursor with ShowCursor
.
ShowCursor(FALSE);//hides the cursor
ShowCursor(TRUE);//shows it again
You must ensure that every call to hide the cursor is matched by one that shows it again.
Using Static
will solve your problem (with some other stuff to initialize old_value
properly:
Private Sub Worksheet_Change(ByVal Target As Range)
Static old_value As String
Dim inited as Boolean 'Used to detect first call and fill old_value
Dim new_value As String
If Not Intersect(cell, Range("cell_of_interest")) Is Nothing Then
new_value = Range("cell_of_interest").Value
If Not inited Then
inited = True
Else
Call DoFoo (old_value, new_value)
End If
old_value = new_value
Next cell
End Sub
In workbook code, force call of Worksheet_change
to fill old_value
:
Private Sub Private Sub Workbook_Open()
SheetX.Worksheet_Change SheetX.Range("cell_of_interest")
End Sub
Note, however, that ANY solution based in VBA variables (including dictionary and another more sophisticate methods) will fail if you stop (Reset) running code (eg. while creating new macros, debugging some code, ...). To avoid such, consider using alternative storage methods (hidden worksheet, for example).
I think you should be able to follow the method used in this post. It looks really ugly, but I would think you could do it twice and get the result you want.
I wonder if this is actually a case where you'd be better off using DataContext.ExecuteCommand(...)
instead of converting to linq.
This may be a dead thread, but I tend to use the following:
public static T? GetValueOrNull<T>(this DbDataRecord reader, string columnName)
where T : struct
{
return reader[columnName] as T?;
}
You are most likely not using the correct credentials for the MySQL server. You also need to ensure the user you are connecting as has the correct privileges to view databases/tables, and that you can connect from your current location in network topographic terms (localhost).
In my case, heredoc caused the issue. There is no problem with PHP version 7.3 up. Howerver, it error with PHP 7.0.33 if you use heredoc with space.
My example code
$rexpenditure = <<<Expenditure
<tr>
<td>$row->payment_referencenumber</td>
<td>$row->payment_requestdate</td>
<td>$row->payment_description</td>
<td>$row->payment_fundingsource</td>
<td>$row->payment_agencyulo</td>
<td>$row->payment_agencyproject</td>
<td>$$row->payment_disbustment</td>
<td>$row->payment_payeename</td>
<td>$row->payment_processpayment</td>
</tr>
Expenditure;
It will error if there is a space on PHP 7.0.33.
When the table is very large, it's better to delete table itself with drop table TableName
and recreate it, if one has create table query; rather than deleting records one by one, using delete from
statement because that can be time consuming.
That doesn't work because distToPoint
is inside your class, so you need to prefix it with the classname if you want to refer to it, like this: classname.distToPoint(self, p)
. You shouldn't do it like that, though. A better way to do it is to refer to the method directly through the class instance (which is the first argument of a class method), like so: self.distToPoint(p)
.
Another approach is to generate an 100 items array with ascending numbers and sort it randomly. This leads actually to a really short and (in my opinion) simple snippet.
const numbers = Array(100).fill().map((_, index) => index + 1);_x000D_
numbers.sort(() => Math.random() - 0.5);_x000D_
console.log(numbers.slice(0, 8));
_x000D_
Probably the easiest way for any list would be:
listA.containsAll(listB) && listB.containsAll(listA)
You just need to put "group(1)" instead of "group()" in the following line and the return will be the one you expected:
System.out.println("I found the text: " + matcher.group(**1**).toString());
I had the same issue, and it was solved when I used a for
loop instead of foreach
.
// foreach (var item in itemsToBeLast)
for (int i = 0; i < itemsToBeLast.Count; i++)
{
var matchingItem = itemsToBeLast.FirstOrDefault(item => item.Detach);
if (matchingItem != null)
{
itemsToBeLast.Remove(matchingItem);
continue;
}
allItems.Add(itemsToBeLast[i]);// (attachDetachItem);
}
By using following code you can copy any class object to another class object for same name and same type of properties.
public class CopyClass
{
/// <summary>
/// Copy an object to destination object, only matching fields will be copied
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="sourceObject">An object with matching fields of the destination object</param>
/// <param name="destObject">Destination object, must already be created</param>
public static void CopyObject<T>(object sourceObject, ref T destObject)
{
// If either the source, or destination is null, return
if (sourceObject == null || destObject == null)
return;
// Get the type of each object
Type sourceType = sourceObject.GetType();
Type targetType = destObject.GetType();
// Loop through the source properties
foreach (PropertyInfo p in sourceType.GetProperties())
{
// Get the matching property in the destination object
PropertyInfo targetObj = targetType.GetProperty(p.Name);
// If there is none, skip
if (targetObj == null)
continue;
// Set the value in the destination
targetObj.SetValue(destObject, p.GetValue(sourceObject, null), null);
}
}
}
Call Method Like,
ClassA objA = new ClassA();
ClassB objB = new ClassB();
CopyClass.CopyObject(objOfferMast, ref objB);
It will copy objA
into objB
.
You will need to alter table abc modify (salary default 0);
A solution for me:
$old_ErrorActionPreference = $ErrorActionPreference
$ErrorActionPreference = 'SilentlyContinue'
if((Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) -eq $null) {
WriteTraceForTrans "The session configuration MyShellUri is already unregistered."
}
else {
#Unregister-PSSessionConfiguration -Name "MyShellUri" -Force -ErrorAction Ignore
}
$ErrorActionPreference = $old_ErrorActionPreference
Or use try-catch
try {
(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue)
}
catch {
}
a more modern approach would be to use css flex-box.
div {_x000D_
height: 50px;_x000D_
background: grey;_x000D_
display: flex;_x000D_
align-items: center_x000D_
}
_x000D_
<div>_x000D_
<label for='name'>Name:</label>_x000D_
<input type='text' id='name' />_x000D_
</div>
_x000D_
a more complex example... if you have multible elements in the flex flow, you can use align-self to align single elements differently to the specified align...
div {_x000D_
display: flex;_x000D_
align-items: center_x000D_
}_x000D_
_x000D_
* {_x000D_
margin: 10px_x000D_
}_x000D_
_x000D_
label {_x000D_
align-self: flex-start_x000D_
}
_x000D_
<div>_x000D_
<img src="https://de.gravatar.com/userimage/95932142/195b7f5651ad2d4662c3c0e0dccd003b.png?size=50" />_x000D_
<label>Text</label>_x000D_
<input placeholder="Text" type="text" />_x000D_
</div>
_x000D_
its also super easy to center horizontally and vertically:
div {_x000D_
position:absolute;_x000D_
top:0;left:0;right:0;bottom:0;_x000D_
background: grey;_x000D_
display: flex;_x000D_
align-items: center;_x000D_
justify-content:center_x000D_
}
_x000D_
<div>_x000D_
<label for='name'>Name:</label>_x000D_
<input type='text' id='name' />_x000D_
</div>
_x000D_

A lot of these answers won't actually work, having tried them myself. Give this a go:
string filepath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
DirectoryInfo d = new DirectoryInfo(filepath);
foreach (var file in d.GetFiles("*.txt"))
{
Directory.Move(file.FullName, filepath + "\\TextFiles\\" + file.Name);
}
It will move all .txt files on the desktop to the folder TextFiles
.
var html = "<p>Hello, <b>World</b>";
var div = document.createElement("div");
div.innerHTML = html;
alert(div.innerText); // Hello, World
That pretty much the best way of doing it, you're letting the browser do what it does best -- parse HTML.
Edit: As noted in the comments below, this is not the most cross-browser solution. The most cross-browser solution would be to recursively go through all the children of the element and concatenate all text nodes that you find. However, if you're using jQuery, it already does it for you:
alert($("<p>Hello, <b>World</b></p>").text());
Check out the text method.
The best way of doing it is to just trigger bootstraps click event with a hover. This way, it should still remain touch device friendly
$('.dropdown').hover(function(){
$('.dropdown-toggle', this).trigger('click');
});
Here is simple way to do it: var num = Number(str); in this example str is the variable that contains the string. You can tested and see how it works open: Google chrome developer tools, then go to the console and paste the following code. read the comments to understand better how the conversion is done.
// Here Im creating my variable as a string
var str = "258";
// here im printing the string variable: str
console.log ( str );
// here Im using typeof , this tells me that the variable str is the type: string
console.log ("The variable str is type: " + typeof str);
// here is where the conversion happens
// Number will take the string in the parentesis and transform it to a variable num as type: number
var num = Number(str);
console.log ("The variable num is type: " + typeof num);
SELECT d.DEPTNO
, d.dname

The easiest way to convert an ISO-8859-1 string to UTF-8 string.
private static String convertIsoToUTF8(String example) throws UnsupportedEncodingException {
return new String(example.getBytes("ISO-8859-1"), "utf-8");
}
If we want to convert an UTF-8 string to ISO-8859-1 string.
private static String convertUTF8ToISO(String example) throws UnsupportedEncodingException {
return new String(example.getBytes("utf-8"), "ISO-8859-1");
}
Moreover, a method that converts an ISO-8859-1 string to UTF-8 string without using the constructor of class String.
public static String convertISO_to_UTF8_personal(String strISO_8859_1) {
String res = "";
int i = 0;
for (i = 0; i < strISO_8859_1.length() - 1; i++) {
char ch = strISO_8859_1.charAt(i);
char chNext = strISO_8859_1.charAt(i + 1);
if (ch <= 127) {
res += ch;
} else if (ch == 194 && chNext >= 128 && chNext <= 191) {
res += chNext;
} else if(ch == 195 && chNext >= 128 && chNext <= 191){
int resNum = chNext + 64;
res += (char) resNum;
} else if(ch == 194){
res += (char) 173;
} else if(ch == 195){
res += (char) 224;
}
}
char ch = strISO_8859_1.charAt(i);
if (ch <= 127 ){
res += ch;
}
return res;
}
}
That method is based on enconding utf-8 to iso-8859-1 of this website. Encoding utf-8 to iso-8859-1
The short answer is that you can't do it using JavaScript alone. You'd need a server-side handler to connect with the SMTP server to actually send the mail. There are many simple mail scripts online, such as this one for PHP:
Using a script like that, you'd POST the contents of your web form to the script, using a function like this:
And then the script would take those values, plus a username and password for the mail server, and connect to the server to send the mail.
You forget a '}' before the last line (to close the "methods {...").

Surprisingly there is no accepted answer. The issue only exists in 32-bit PHP.
From the documentation,
If the string does not contain any of the characters '.', 'e', or 'E' and the numeric value fits into integer type limits (as defined by PHP_INT_MAX), the string will be evaluated as an integer. In all other cases it will be evaluated as a float.
In other words, the $string
is first interpreted as INT, which cause overflow (The $string
value 2968789218 exceeds the maximum value (PHP_INT_MAX
) of 32-bit PHP, which is 2147483647.), then evaluated to float by (float)
or floatval()
.
Thus, the solution is:
$string = "2968789218";
echo 'Original: ' . floatval($string) . PHP_EOL;
$string.= ".0";
$float = floatval($string);
echo 'Corrected: ' . $float . PHP_EOL;
which outputs:
Original: 2.00
Corrected: 2968789218
To check whether your PHP is 32-bit or 64-bit, you can:
echo PHP_INT_MAX;
If your PHP is 64-bit, it will print out 9223372036854775807
, otherwise it will print out 2147483647
.
to access data in a stdClass in similar fashion you do with an asociative array just use the {$var} syntax.
$myObj = new stdClass;
$myObj->Prop1 = "Something";
$myObj->Prop2 = "Something else";
// then to acces it directly
echo $myObj->{'Prop1'};
echo $myObj->{'Prop2'};
// or what you may want
echo $myObj->{$myStringVar};
public static final void generateRange(final Date dateFrom, final Date dateTo)
{
final Calendar current = Calendar.getInstance();
current.setTime(dateFrom);
while (!current.getTime().after(dateTo))
{
// TODO
current.add(Calendar.DATE, 1);
}
}
Using XAML:
If you know the other assembly
structure and want the resources
in c# code, then use below code:
ResourceDictionary dictionary = new ResourceDictionary();
dictionary.Source = new Uri("pack://application:,,,/WpfControlLibrary1;Component/RD1.xaml", UriKind.Absolute);
foreach (var item in dictionary.Values)
{
//operations
}
Output: If we want to use ResourceDictionary
RD1.xaml
of Project WpfControlLibrary1
into StackOverflowApp
project.
Structure of Projects:
Code Output:
PS: All ResourceDictionary
Files should have Build Action
as 'Resource
' or 'Page

For arbitrary, potentially large number of optional parameters, a nice idiom is to use Functional options.
For your type Foobar
, first write only one constructor:
func NewFoobar(options ...func(*Foobar) error) (*Foobar, error){
fb := &Foobar{}
// ... (write initializations with default values)...
for _, op := range options{
err := op(fb)
if err != nil {
return nil, err
}
}
return fb, nil
}
where each option is a function which mutates the Foobar. Then provide convenient ways for your user to use or create standard options, for example :
func OptionReadonlyFlag(fb *Foobar) error {
fb.mutable = false
return nil
}
func OptionTemperature(t Celsius) func(*Foobar) error {
return func(fb *Foobar) error {
fb.temperature = t
return nil
}
}
For conciseness, you may give a name to the type of the options (Playground) :
type OptionFoobar func(*Foobar) error
If you need mandatory parameters, add them as first arguments of the constructor before the variadic options
.
The main benefits of the Functional options idiom are :
This technique was coined by Rob Pike and also demonstrated by Dave Cheney.
Try the following:
int myIndex = MyDataGrid.SelectedIndex;
This will give the index of the row which is currently selected.

Angular comes with a limitTo:limit filter, it support limiting first x items and last x items:
<div ng-repeat="item in items|limitTo:4">{{item}}</div>
I didn't understand your problem clearly but I think this is what you're looking for(Based on my understanding)
person = {"name"=>"BillGates", "company_name"=>"Microsoft", "position"=>"Chairman"}
person.delete_if {|key, value| key == "name"} #doing something if the key == "something"
Output: {"company_name"=>"Microsoft", "position"=>"Chairman"}
I've found this solution that works better for me. You can use this:
$('.modal').css({
'width': function () {
return ($(document).width() * .9) + 'px';
},
'margin-left': function () {
return -($(this).width() / 2);
}
});
or this depending your requirements:
$('.modal').css({
width: 'auto',
'margin-left': function () {
return -($(this).width() / 2);
}
});
See the post where I found that: https://github.com/twitter/bootstrap/issues/675
I'm answering only the part of the question about zbar
installation.
I spent nearly half an hour a few hours to make it work on Windows + Python 2.7 64-bit, so here are additional notes to the accepted answer:
Install it with pip install zbar-0.10-cp27-none-win_amd64.whl
If Python reports an ImportError: DLL load failed: The specified module could not be found.
when doing import zbar
, then you will just need to install the Visual C++ Redistributable Packages for VS 2013 (I spent a lot of time here, trying to recompile unsuccessfully...)
Required too: libzbar64-0.dll must be in a folder which is in the PATH. In my case I copied it to "C:\Python27\libzbar64-0.dll" (which is in the PATH). If it still does not work, add this:
import os
os.environ['PATH'] += ';C:\\Python27'
import zbar
PS: Making it work with Python 3.x is even more difficult: Compile zbar for Python 3.x.
PS2: I just tested pyzbar with pip install pyzbar
and it's MUCH easier, it works out-of-the-box (the only thing is you need to have VC Redist 2013 files installed). It is also recommended to use this library in this pyimagesearch.com article.
null
is a legal value (and reserved word) in JSON, but some environments do not have a "NULL" object (as opposed to a NULL
value) and hence cannot accurately represent the JSON null
. So they will sometimes represent it as an empty array.
Whether null
is a legal value in that particular element of that particular API is entirely up to the API designer.
You're storing all (sub-) files and folder recursively in a list, but with your current code you store the parent folder before you store the children. And so you try to delete the folder before it is empty. Try this code:
if(tempFile.isDirectory()) {
// children first
fetchCompleteList(filesList, folderList, tempFile.getAbsolutePath());
// parent folder last
folderList.add(tempFile.getAbsolutePath());
}
svn checkout https://example.org/path/to/repo/bleh
svn add file1 file2...
svn commit
I am not aware of a quicker option.
Note: if you are on the same machine as your Subversion repository, the URL can use the file:
specifier with a path in place of https:
in the svn checkout
command. For example svn checkout file:///path/to/repo/bleh
.
PS. as pointed out in the comments and other answers, you can use something like svn import . <URL>
if you want to recursively import everything in the current directory. With this option, however, you can't skip over some of the files; it's all or nothing.

It isn't impossible. The number of records in the left table is the minimum number of records it will return. If the right table has two records that match to one record in the left table, it will return two records.
I like the backwards iterator at the end of Yakk - Adam Nevraumont's answer, but it seemed complicated for what I needed, so I wrote this:
template <class T>
class backwards {
T& _obj;
public:
backwards(T &obj) : _obj(obj) {}
auto begin() {return _obj.rbegin();}
auto end() {return _obj.rend();}
};
I'm able to take a normal iterator like this:
for (auto &elem : vec) {
// ... my useful code
}
and change it to this to iterate in reverse:
for (auto &elem : backwards(vec)) {
// ... my useful code
}
It's not open source, but you can at least get a free personal use license to Prince, which really does a lovely job.
If someone like me want to do it with query builder in Laravel 5.2.23 it can be done like ->
$searchResultQuery = Users::query();
$searchResultQuery->where('status_message', '<>', '', 'and'); // is not null
$searchResultQuery->where('is_deleted', 'IS NULL', null, 'and'); // is null
Or with scope in model :
public function scopeNotNullOnly($query){
return $query->where('status_message', '<>', '');
}
You did two mistakes . I think you misplace FROM and WHERE keywords.
SELECT DISTINCT Description, Date as treatmentDate

Rather than type this in at the "psql" prompt I would suggest you copy it to a file and then pass the file as input to psql using the "--file" or "-f" options:
psql -f clean_all_pg.sql
Credit where credit is due: I wrote the function, but think the queries (or the first one at least) came from someone on one of the pgsql mailing lists years ago. Don't remember exactly when or which one.
Another approach is using UnboundID. Its api is very readable and shorter

Your first option is the good one. It's the least problematic one and you've already found the correct reasons why you couldn't use the other options.

You can see the official sample from Android Developer.
/**
* Open a web page of a specified URL
*
* @param url URL to open
*/
public void openWebPage(String url) {
Uri webpage = Uri.parse(url);
Intent intent = new Intent(Intent.ACTION_VIEW, webpage);
if (intent.resolveActivity(getPackageManager()) != null) {
startActivity(intent);
}
}
Please have a look at the constructor of Intent
:
public Intent (String action, Uri uri)
You can pass android.net.Uri
instance to the 2nd parameter, and a new Intent is created based on the given data url.
And then, simply call startActivity(Intent intent)
to start a new Activity, which is bundled with the Intent with the given URL.
if
check statement?Yes. The docs says:
If there are no apps on the device that can receive the implicit intent, your app will crash when it calls startActivity(). To first verify that an app exists to receive the intent, call resolveActivity() on your Intent object. If the result is non-null, there is at least one app that can handle the intent and it's safe to call startActivity(). If the result is null, you should not use the intent and, if possible, you should disable the feature that invokes the intent.
You can write in one line when creating the Intent instance like below:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
REST means working with the standards of the web, and the standard for "secure" transfer on the web is SSL. Anything else is going to be kind of funky and require extra deployment effort for clients, which will have to have encryption libraries available.
Once you commit to SSL, there's really nothing fancy required for authentication in principle. You can again go with web standards and use HTTP Basic auth (username and secret token sent along with each request) as it's much simpler than an elaborate signing protocol, and still effective in the context of a secure connection. You just need to be sure the password never goes over plain text; so if the password is ever received over a plain text connection, you might even disable the password and mail the developer. You should also ensure the credentials aren't logged anywhere upon receipt, just as you wouldn't log a regular password.
HTTP Digest is a safer approach as it prevents the secret token being passed along; instead, it's a hash the server can verify on the other end. Though it may be overkill for less sensitive applications if you've taken the precautions mentioned above. After all, the user's password is already transmitted in plain-text when they log in (unless you're doing some fancy JavaScript encryption in the browser), and likewise their cookies on each request.
Note that with APIs, it's better for the client to be passing tokens - randomly generated strings - instead of the password the developer logs into the website with. So the developer should be able to log into your site and generate new tokens that can be used for API verification.
The main reason to use a token is that it can be replaced if it's compromised, whereas if the password is compromised, the owner could log into the developer's account and do anything they want with it. A further advantage of tokens is you can issue multiple tokens to the same developers. Perhaps because they have multiple apps or because they want tokens with different access levels.
(Updated to cover implications of making the connection SSL-only.)
You can't declare multiple types in the initialization, but you can assign to multiple types E.G.
{
int i;
char x;
for(i = 0, x = 'p'; ...){
...
}
}
Just declare them in their own scope.
Do that like this
db.Users.OrderByDescending(u => u.UserId).FirstOrDefault();
To put text, use .text('text')
If you want to use .html(SomeValue)
, SomeValue should have html tags that can be inside a div it must work too.
Just check your script location, as farzad said.
When you read from a binary file, a data type called bytes is used. This is a bit like list or tuple, except it can only store integers from 0 to 255.
Try:
file_size = fin.read(4)
file_size0 = file_size[0]
file_size1 = file_size[1]
file_size2 = file_size[2]
file_size3 = file_size[3]
Or:
file_size = list(fin.read(4))
Instead of:
file_size = int(fin.read(4))
int min and max values
Int -2,147,483,648 / 2,147,483,647 Int 64 -9,223,372,036,854,775,808 / 9,223,372,036,854,775,807
i guess you could set a to equal 9,223,372,036,854,775,807 but it would need to be an int64
if you always want a to be grater that b why do you need to check it? just set it to be true always

will generate points of twice the normal size, but for plot ... with dots ps 2
the "ps 2
" part is ignored.
You could use circular points (pt 7
), which look just like dots.
For hiding a widget you can use function pack_forget() and to again show it you can use pack() function and implement them both in separate functions.
from Tkinter import *
root = Tk()
label=Label(root,text="I was Hidden")
def labelactive():
label.pack()
def labeldeactive():
label.pack_forget()
Button(root,text="Show",command=labelactive).pack()
Button(root,text="Hide",command=labeldeactive).pack()
root.mainloop()
I have used a script but to make a join, maybe I can help you
string Email = String.Join(", ", Emails.Where(i => i.Email != "").Select(i => i.Email).Distinct());
This also works

Yes, case insensitivity can be enabled and disabled at will in Java regex.
It looks like you want something like this:
System.out.println(
"Have a meRry MErrY Christmas ho Ho hO"
.replaceAll("(?i)\\b(\\w+)(\\s+\\1)+\\b", "$1")
);
// Have a meRry Christmas ho
Note that the embedded Pattern.CASE_INSENSITIVE
flag is (?i)
not \?i
. Note also that one superfluous \b
has been removed from the pattern.
The (?i)
is placed at the beginning of the pattern to enable case-insensitivity. In this particular case, it is not overridden later in the pattern, so in effect the whole pattern is case-insensitive.
It is worth noting that in fact you can limit case-insensitivity to only parts of the whole pattern. Thus, the question of where to put it really depends on the specification (although for this particular problem it doesn't matter since \w
is case-insensitive.
To demonstrate, here's a similar example of collapsing runs of letters like "AaAaaA"
to just "A"
.
System.out.println(
"AaAaaA eeEeeE IiiIi OoooOo uuUuUuu"
.replaceAll("(?i)\\b([A-Z])\\1+\\b", "$1")
); // A e I O u
Now suppose that we specify that the run should only be collapsed only if it starts with an uppercase letter. Then we must put the (?i)
in the appropriate place:
System.out.println(
"AaAaaA eeEeeE IiiIi OoooOo uuUuUuu"
.replaceAll("\\b([A-Z])(?i)\\1+\\b", "$1")
); // A eeEeeE I O uuUuUuu
More generally, you can enable and disable any flag within the pattern as you wish.
java.util.regex.Pattern
/regex/i
(Pattern.CASE_INSENSITIVE
in Java), you can do /(?i)regex/
/first(?i)second(?-i)third/
/first(?i:second)third/
\b
between a \w
and a \s
)One simple way to do this is :
Go to Preferences -> Package Settings -> Your Theme Name -> Activation
In my case I installed Boxy Theme so the path will be
Preferences -> Package Settings -> Boxy Theme -> Activation
Then there will be a pop-up menu that will let you choose which type of the theme package you want to activate.
Use up and down arrow so choose then press enter or simply click the one you want to choose.
This is steps only applicable if the theme installed also customized the sublime text 3 sidebar.
Hope it help anyone!
You have to encode your parameters.
Something like this will do:
import java.net.*;
import java.io.*;
public class EncodeParameter {
public static void main( String [] args ) throws URISyntaxException ,
UnsupportedEncodingException {
String myQuery = "^IXIC";
URI uri = new URI( String.format(
"http://finance.yahoo.com/q/h?s=%s",
URLEncoder.encode( myQuery , "UTF8" ) ) );
System.out.println( uri );
}
}

Note: if you're using(importing) org.json.simple.JSONArray
, you have to use JSONArray.size()
to get the data you want. But use JSONArray.length()
if you're using org.json.JSONArray
.
=if([Logical Test 1],[Action 1],if([Logical Test 2],[Action 1],if([Logical Test 3],[Action 3],[Value if all logical tests return false])))
Replace the components in the square brackets as necessary.
"cell one","cell "" two","cell "" ,three"
Save this to csv file and see the results, so double quote is used to escape itself
Important Note
"cell one","cell "" two", "cell "" ,three"
will give you a different result because there is a space after the comma, and that will be treated as "

Since IPv6-Adresses are written in Hex-notation you can use "Hexspeak" (numbers 0-9 and letters a-f) in Adresses.
There are a number of words you can use as valid adresses to better momorize them.
If you ping6 www.facebook.com -n
you will get something like "2a03:2880:f01c:601:face:b00c:0:1".
Here are some examples:
When running Wget with -r
or -p
, but without -N
, -nd
, or -nc
, re-downloading a file will result in the new copy simply overwriting the old.
So adding -nc
will prevent this behavior, instead causing the original version to be preserved and any newer copies on the server to be ignored.
The underlying problem revolves around accessing the data within the array, as Felix Kling points out in the first response.
In the following code, I've accessed the values of the array with the print and echo constructs.
function data()
{
$a = "abc";
$b = "def";
$c = "ghi";
$array = array($a, $b, $c);
print_r($array);//outputs the key/value pair
echo "<br>";
echo $array[0].$array[1].$array[2];//outputs a concatenation of the values
}
data();
$array = str_split("$string");
will actuall work pretty fine, BUT if you want to preserve the special characters in that string, and you want to do some manipulation with them, THAN I would use
do {
$array[] = mb_substr( $string, 0, 1, 'utf-8' );
} while ( $string = mb_substr( $string, 1, mb_strlen( $string ), 'utf-8' ) );
because for some of mine personal uses, it has been shown to be more reliable when there is an issue with special characters
On Chrome's latest update (38.0.2125.104 m at the moment), Google added the option to know whether the files loaded to the website were newly downloaded from the server - or read from the local cache.
When an error like yours "hits" the console - you know the files were just downloaded from the server and not read from the local cache. You can recreate this error by clicking Ctrl + F5 (refresh and erase cache).
It fits your description where Firebug (or equivalents) doesn't fire any errors to the console - whilst Chrome does.
So, the bottom line is - your're just fine and you can ignore this error - it's merely an indicator.
you can use the below code to bring focus to a div, in this example the page scrolls to the <div id="navigation">
$('html, body').animate({ scrollTop: $('#navigation').offset().top }, 'slow');
Hide scroll bar, but while still being able to scroll using CSS
To hide the scrollbar use -webkit- because it is supported by major browsers (Google Chrome, Safari or newer versions of Opera). There are many other options for the other browsers which are listed below:
-webkit- (Chrome, Safari, newer versions of Opera):
.element::-webkit-scrollbar { width: 0 !important }
-moz- (Firefox):
.element { overflow: -moz-scrollbars-none; }
-ms- (Internet Explorer +10):
.element { -ms-overflow-style: none; }

}
Its a good practice separate javascript of html
Select a range of cells (the entire column in this case), type in your formula, and hold down Ctrl while you press Enter. This places the formula in all selected cells.
You have to override the bootstrap default by being a bit more specific. Try this for a black background:
html body {
background-color: rgba(0,0,0,1.00);

Neither <iostream>
nor <iostream.h>
are standard C header files. Your code is meant to be C++, where <iostream>
is a valid header. Use g++
(and a .cpp
file extension) for C++ code.
Alternatively, this program uses mostly constructs that are available in C anyway. It's easy enough to convert the entire program to compile using a C compiler. Simply remove #include <iostream>
and using namespace std;
, and replace cout << endl;
with putchar('\n');
... I advise compiling using C99 (eg. gcc -std=c99
)

WOW, I gotta say: keep it simple:
MessageBox.Show("Result: " + (DateTime.Now.AddDays(10) > DateTime.Now));
Result: True
and:
MessageBox.Show("Result: " + DateTime.Now.AddDays(10).Subtract(DateTime.Now));
Result: 10.00:00:00
The DateTime object has all the builtin logic to handle the Boolean result.
Building off @Marc's solution -- since the bullet character is rendered differently with different fonts and browsers, I used the following css3 technique with border-radius to make a bullet that I have more control over:
li:before {
content: '';
background-color: #898989;
display: inline-block;
position: relative;
height: 12px;
width: 12px;
border-radius: 6px;
-webkit-border-radius: 6px;
-moz-border-radius: 6px;
-moz-background-clip: padding;
-webkit-background-clip: padding-box;
background-clip: padding-box;
margin-right: 4px;
top: 2px;
}
Creating a text file in unix can be done through a text editor (vim, emacs, gedit, etc). But what you want might be something like this
echo "insert text here" > myfile.txt
That will put the text 'insert text here' into a file myfile.txt. To verify that this worked use the command 'cat'.
cat myfile.txt
If you want to append to a file use this
echo "append this text" >> myfile.txt
Change your code as follows -
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
var form=$("#myForm");
$("#smt").click(function(){
$.ajax({
type:"POST",
url:form.attr("action"),
data:form.serialize(),
success: function(response){
if(response == 1){
$("#err").html("Hi Tony");//updated
} else {
$("#err").html("I dont know you.");//updated
}
}
});
});
});
</script>
PHP -
<?php
$user=$_POST['user'];
$pass=$_POST['pass'];
if($user=="tony")
{
echo 1;

Here is my solution for key phrases of the messages: “unable to find valid certification path” and “PKIX path building failed“.
These phrases are shown when a SSL certification file can not be found.
Open https://jcenter.bintray.com/ in your browse and export the certificate in cer format.
Put the certificate in Android Studio’s cert folder
{your-home-directory}/.AndroidStudio3.0/system/tasks/cacerts
Then all went well.

There are many articles about writing code to import an excel file, but this is a manual/shortcut version:
If you don't need to import your Excel file programmatically using code you can do it very quickly using the menu in SQL Management Studio.
The quickest way to get your Excel file into SQL is by using the import wizard:
The next window is 'Choose a Data Source', select Excel:
In the 'Data Source' dropdown list select Microsoft Excel (this option should appear automatically if you have excel installed).
Click the 'Browse' button to select the path to the Excel file you want to import.
On the 'Specify Table Copy or Query' window:
'Select Source Tables:' choose the worksheet(s) from your Excel file and specify a destination table for each worksheet. If you don't have a table yet the wizard will very kindly create a new table that matches all the columns from your spreadsheet. Click Next.
e= StringVar()
def fileDialog():
filename = filedialog.askopenfilename(initialdir = "/",title = "Select A
File",filetype = (("jpeg","*.jpg"),("png","*.png"),("All Files","*.*")))
e.set(filename)
la = Entry(self,textvariable = e,width = 30).place(x=230,y=330)
butt=Button(self,text="Browse",width=7,command=fileDialog).place(x=430,y=328)
Try Case
SELECT stock.name,
CASE
WHEN stock.quantity <20 THEN 'Buy urgent'
ELSE 'There is enough'
END

First, try omitting the quotes from 12 and 24. Worth a shot.
Second, it's better to do this in CSS. See also http://www.w3schools.com/css/css_font.asp . Here is an inline style for a table tag:
<table style='font-family:"Courier New", Courier, monospace; font-size:80%' ...>...</table>
Better still, use an external style sheet or a style tag near the top of your HTML document. See also http://www.w3schools.com/css/css_howto.asp .

Try the following commands to search the string inside all previous tracked files:
git log --patch | less +/searching_string
or
git rev-list --all | GIT_PAGER=cat xargs git grep 'search_string'
which needs to be run from the parent directory where you'd like to do the searching.
Go to prompt command and type "adb devices". If it is empty, then make sure you allowed for "MTP Transfer" or similar and you enabled debugging on your phone.
To enable debugging, follow this tutorial: https://www.kingoapp.com/root-tutorials/how-to-enable-usb-debugging-mode-on-android.htm
Then type "adb devices" again. If a device is listed in there, then it should work now.
Option 1: Load both images as arrays (scipy.misc.imread
) and calculate an element-wise (pixel-by-pixel) difference. Calculate the norm of the difference.
Option 2: Load both images. Calculate some feature vector for each of them (like a histogram). Calculate distance between feature vectors rather than images.
However, there are some decisions to make first.
You should answer these questions first:
Are images of the same shape and dimension?
If not, you may need to resize or crop them. PIL library will help to do it in Python.
If they are taken with the same settings and the same device, they are probably the same.
Are images well-aligned?
If not, you may want to run cross-correlation first, to find the best alignment first. SciPy has functions to do it.
If the camera and the scene are still, the images are likely to be well-aligned.
Is exposure of the images always the same? (Is lightness/contrast the same?)
If not, you may want to normalize images.
But be careful, in some situations this may do more wrong than good. For example, a single bright pixel on a dark background will make the normalized image very different.
Is color information important?
If you want to notice color changes, you will have a vector of color values per point, rather than a scalar value as in gray-scale image. You need more attention when writing such code.
Are there distinct edges in the image? Are they likely to move?
If yes, you can apply edge detection algorithm first (e.g. calculate gradient with Sobel or Prewitt transform, apply some threshold), then compare edges on the first image to edges on the second.
Is there noise in the image?
All sensors pollute the image with some amount of noise. Low-cost sensors have more noise. You may wish to apply some noise reduction before you compare images. Blur is the most simple (but not the best) approach here.
What kind of changes do you want to notice?
This may affect the choice of norm to use for the difference between images.
Consider using Manhattan norm (the sum of the absolute values) or zero norm (the number of elements not equal to zero) to measure how much the image has changed. The former will tell you how much the image is off, the latter will tell only how many pixels differ.
I assume your images are well-aligned, the same size and shape, possibly with different exposure. For simplicity, I convert them to grayscale even if they are color (RGB) images.
You will need these imports:
import sys
from scipy.misc import imread
from scipy.linalg import norm
from scipy import sum, average
Main function, read two images, convert to grayscale, compare and print results:
def main():
file1, file2 = sys.argv[1:1+2]
# read images as 2D arrays (convert to grayscale for simplicity)
img1 = to_grayscale(imread(file1).astype(float))
img2 = to_grayscale(imread(file2).astype(float))
# compare
n_m, n_0 = compare_images(img1, img2)
print "Manhattan norm:", n_m, "/ per pixel:", n_m/img1.size
print "Zero norm:", n_0, "/ per pixel:", n_0*1.0/img1.size
How to compare. img1
and img2
are 2D SciPy arrays here:
def compare_images(img1, img2):
# normalize to compensate for exposure difference, this may be unnecessary
# consider disabling it
img1 = normalize(img1)
img2 = normalize(img2)
# calculate the difference and its norms
diff = img1 - img2 # elementwise for scipy arrays
m_norm = sum(abs(diff)) # Manhattan norm
z_norm = norm(diff.ravel(), 0) # Zero norm
return (m_norm, z_norm)
If the file is a color image, imread
returns a 3D array, average RGB channels (the last array axis) to obtain intensity. No need to do it for grayscale images (e.g. .pgm
):
def to_grayscale(arr):
"If arr is a color image (3D array), convert it to grayscale (2D array)."
if len(arr.shape) == 3:
return average(arr, -1) # average over the last axis (color channels)
else:
return arr
Normalization is trivial, you may choose to normalize to [0,1] instead of [0,255]. arr
is a SciPy array here, so all operations are element-wise:
def normalize(arr):
rng = arr.max()-arr.min()
amin = arr.min()
return (arr-amin)*255/rng
Run the main
function:
if __name__ == "__main__":
main()
Now you can put this all in a script and run against two images. If we compare image to itself, there is no difference:
$ python compare.py one.jpg one.jpg
Manhattan norm: 0.0 / per pixel: 0.0
Zero norm: 0 / per pixel: 0.0
If we blur the image and compare to the original, there is some difference:
$ python compare.py one.jpg one-blurred.jpg
Manhattan norm: 92605183.67 / per pixel: 13.4210411116
Zero norm: 6900000 / per pixel: 1.0
P.S. Entire compare.py script.
As the question is about a video sequence, where frames are likely to be almost the same, and you look for something unusual, I'd like to mention some alternative approaches which may be relevant:
I strongly recommend taking a look at “Learning OpenCV” book, Chapters 9 (Image parts and segmentation) and 10 (Tracking and motion). The former teaches to use Background subtraction method, the latter gives some info on optical flow methods. All methods are implemented in OpenCV library. If you use Python, I suggest to use OpenCV = 2.3, and its cv2
Python module.
The most simple version of the background subtraction:
More advanced versions make take into account time series for every pixel and handle non-static scenes (like moving trees or grass).
The idea of optical flow is to take two or more frames, and assign velocity vector to every pixel (dense optical flow) or to some of them (sparse optical flow). To estimate sparse optical flow, you may use Lucas-Kanade method (it is also implemented in OpenCV). Obviously, if there is a lot of flow (high average over max values of the velocity field), then something is moving in the frame, and subsequent images are more different.
Comparing histograms may help to detect sudden changes between consecutive frames. This approach was used in Courbon et al, 2010:
Similarity of consecutive frames. The distance between two consecutive frames is measured. If it is too high, it means that the second frame is corrupted and thus the image is eliminated. The Kullback–Leibler distance, or mutual entropy, on the histograms of the two frames:
where p and q are the histograms of the frames is used. The threshold is fixed on 0.2.

It's not possible using CSS, but using a CSS preprocessor like less or SASS.
Set your SMTP auth to true if using the PHPmailer class:
$mail->SMTPAuth = true;
Policykit is a system daemon and policykit authentication agent is used to verify identity of the user before executing actions. The messages logged in /var/log/secure
show that an authentication agent is registered when user logs in and it gets unregistered when user logs out. These messages are harmless and can be safely ignored.
To resize an image I have better (graphical) results by using this function in stead of DrawInRect:
- (UIImage*) reduceImageSize:(UIImage*) pImage newwidth:(float) pWidth
{
float lScale = pWidth / pImage.size.width;
CGImageRef cgImage = pImage.CGImage;
UIImage *lResult = [UIImage imageWithCGImage:cgImage scale:lScale
orientation:UIImageOrientationRight];
return lResult;
}
Aspect ratio is taken care for automatically
If you are using RABL you can configure it as described here to use JSON.pretty_generate:
class PrettyJson
def self.dump(object)
JSON.pretty_generate(object, {:indent => " "})
end
end
Rabl.configure do |config|
...
config.json_engine = PrettyJson if Rails.env.development?
...
end
A problem with using JSON.pretty_generate is that JSON schema validators will no longer be happy with your datetime strings. You can fix those in your config/initializers/rabl_config.rb with:
ActiveSupport::TimeWithZone.class_eval do
alias_method :orig_to_s, :to_s
def to_s(format = :default)
format == :default ? iso8601 : orig_to_s(format)
end
end
To try to debug this error, first go to your android terminal / console and execute this command:
ps | grep THE_ERROR_PID_YOU_GET_(IT_IS_A_NUMBER)
then if the output comes out as your app... it is your app causing the error. Try to look for empty Strings
that you pass into the layout
.
I had this exact same problem and it was my fault as I was passing an empty String
into my layout. After changing the ""
to " "
this error went away.
If you don't get your app from the console output, then it is something else causing it (probably, as others said, the android keyboard)
