Determining of root cause is not an issue since Go 1.8; field name now is shown in the error message:
json: cannot unmarshal object into Go struct field Comment.author of type string
It's an inlined image (png), encoded in base64. It can make a page faster: the browser doesn't have to query the server for the image data separately, saving a round trip.
(It can also make it slower if abused: these resources are not cached, so the bytes are included in each page load.)

The main difference between return false
and event.preventDefault()
is that your code below return false
will not be executed and in event.preventDefault()
case your code will execute after this statement.
When you write return false it do the following things for you behind the scenes.
* Stops callback execution and returns immediately when called.
* event.stopPropagation();
* event.preventDefault();
You want to look at CodeDOM. It allows defining code elements and compiling them. Quoting MSDN:
...This object graph can be rendered as source code using a CodeDOM code generator for a supported programming language. The CodeDOM can also be used to compile source code into a binary assembly.
Based on Charles Clayton's response, I included some JSDoc, ES6 tweaks, and incorporated suggestions from the comments in the original response.

you have to use rewrite to pass params using proxy_pass here is example I did for angularjs app deployment to s3
S3 Static Website Hosting Route All Paths to Index.html
adopted to your needs would be something like
location /service/ {
rewrite ^\/service\/(.*) /$1 break;
proxy_pass http://apache;
}
if you want to end up in http://127.0.0.1:8080/query/params/
if you want to end up in http://127.0.0.1:8080/service/query/params/ you'll need something like

proxy_pass http://apache;
}
The easiest way is to use os module
>>> import os
>>> clear = lambda: os.system('clear')
>>> clear()
No need for the option, just make the preferred width of the last column the maximum and it will take all the extra space.
table.getColumnModel().getColumn(0).setPreferredWidth(27);
table.getColumnModel().getColumn(1).setPreferredWidth(120);
table.getColumnModel().getColumn(2).setPreferredWidth(100);
table.getColumnModel().getColumn(3).setPreferredWidth(90);
table.getColumnModel().getColumn(4).setPreferredWidth(90);
table.getColumnModel().getColumn(6).setPreferredWidth(120);
table.getColumnModel().getColumn(7).setPreferredWidth(100);
table.getColumnModel().getColumn(8).setPreferredWidth(95);
table.getColumnModel().getColumn(9).setPreferredWidth(40);
table.getColumnModel().getColumn(10).setPreferredWidth(Integer.MAX_INT);
You should have a look at moment
which is a python port of the excellent js lib momentjs
.
One advantage of it is the support of ISO 8601
strings formats, as well as a generic "% format" :
import moment
time_string='2012-10-09T19:00:55Z'
m = moment.date(time_string, '%Y-%m-%dT%H:%M:%SZ')
print m.format('YYYY-M-D H:M')
print m.weekday
Result:
2012-10-09 19:10

You can use boost lexical cast:
#include <boost/lexical_cast.hpp>
string v("0.6");
double dd = boost::lexical_cast<double>(v);
cout << dd << endl;
Note: boost::lexical_cast throws exception so you should be prepared to deal with it when you pass invalid value, try passing string("xxx")
The advantage of passing an owner handle is that the FolderBrowserDialog will not be modal to that window. This prevents the user from interacting with your main application window while the dialog is active.
You can submit your jsp page to servlet. For this use <form>
tag.
And to redirect use:
response.sendRedirect("servleturl")
A bit late to the party, but this is what worked for me:
>>> import sys
>>> sys.path.insert(0, '')
Apparently, if there is an empty string, Python knows that it should look in the current directory. I did not have the empty string in sys.path
, which caused this error.
If you are looking for a way to pass additional URL parameters (not controller, action, id, etc), here's a robust method for doing so:
object_path(@object, params: request.query_parameters)
That will pass along utm parameters or any other additional params you don't want to lose.

You can use StringFormat in Silverlight 4 to provide a custom formatting of the value you bind to.
The date formatting has a huge range of options.
For the DateTime of “April 17, 2004, 1:52:45 PM”
You can either use a set of standard formats (standard formats)…
StringFormat=f : “Saturday, April 17, 2004 1:52 PM”
StringFormat=g : “4/17/2004 1:52 PM”
StringFormat=m : “April 17”
StringFormat=y : “April, 2004”
StringFormat=t : “1:52 PM”
StringFormat=u : “2004-04-17 13:52:45Z”
StringFormat=o : “2004-04-17T13:52:45.0000000”
… or you can create your own date formatting using letters (custom formats)
StringFormat=’MM/dd/yy’ : “04/17/04”
StringFormat=’MMMM dd, yyyy g’ : “April 17, 2004 A.D.”
StringFormat=’hh:mm:ss.fff tt’ : “01:52:45.000 PM”
Yep, why not?
fs.Write(myByteArray, 0, myByteArray.Length);
This problem can also arise if you include jQuery more than once.
Really old post but in case someone is unaware...
In Visual Studio 2015, you can place a breakpoint on the set
accessor of an Auto-Implemented Property and the debugger will break when the property is updated
public bool IsUpdated
{
get;
set; //set breakpoint on this line
}
Update
Alternatively; @AbdulRaufMujahid has pointed out in the comments that if the auto implemented property is on a single line, you can position your cursor at the get;
or set;
and hit F9
and a breakpoint will be placed accordingly. Nice!
public bool IsUpdated { get; set; }
Here's a simplest example from ASP.NET Community, this gave me a clear understanding on the concept....
what difference does this make?
For an example of this, here is a way to put focus on a text box on a page when the page is loaded into the browser—with Visual Basic using the RegisterStartupScript
method:
Page.ClientScript.RegisterStartupScript(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)
This works well because the textbox on the page is generated and placed on the page by the time the browser gets down to the bottom of the page and gets to this little bit of JavaScript.
But, if instead it was written like this (using the RegisterClientScriptBlock
method):
Page.ClientScript.RegisterClientScriptBlock(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)
Focus will not get to the textbox control and a JavaScript error will be generated on the page
The reason for this is that the browser will encounter the JavaScript before the text box is on the page. Therefore, the JavaScript will not be able to find a TextBox1.

It depends on the scenario. If you only want to compute the age of a person, then use a function since you want to implement a single specific behaviour.
But if you want to create an object, that contains the date of birth of a person (and possibly other data), allows to modify it, then computing the age could be one of many operations related to the person and it would be sensible to use a class instead.
Classes provide a way to merge together some data and related operations. If you have only one operation on the data then using a function and passing the data as argument you will obtain an equivalent behaviour, with less complex code.
Note that a class of the kind:
class A(object):
def __init__(self, ...):
#initialize
def a_single_method(self, ...):
#do stuff
isn't really a class, it is only a (complicated)function. A legitimate class should always have at least two methods(without counting __init__
).
this is a mysql function example. I hope it helps. (I have not tested it yet, but should work)

GPS is generally more accurate than network but sometimes GPS is not available, therefore you might need to switch between the two.
A good start might be to look at the android dev site. They had a section dedicated to determining user location and it has all the code samples you need.

I'd suggest adding if rows
in case there is an empty line at the end of the file
import csv
with open('coors.csv', mode='r') as infile:
reader = csv.reader(infile)
with open('coors_new.csv', mode='w') as outfile:
writer = csv.writer(outfile)
mydict = dict(row[:2] for row in reader if row)
When using JUnit asserts, I always make the message nice and clear. It saves huge amounts of time debugging. Doing it this way avoids having to add a added dependency on hamcrest Matchers.
previousTokenValues[1] = "1378994409108";
currentTokenValues[1] = "1378994416509";
Long prev = Long.parseLong(previousTokenValues[1]);
Long curr = Long.parseLong(currentTokenValues[1]);
assertTrue("Previous (" + prev + ") should be greater than current (" + curr + ")", prev > curr);
To get the data form external site by passing using a local proxy as suggested by jherax you can create a php page that fetches the content for you from respective external url and than send a get request to that php page.
var req = new XMLHttpRequest();
req.open('GET', 'http://localhost/get_url_content.php',false);
if(req.status == 200) {
alert(req.responseText);
}
as a php proxy you can use https://github.com/cowboy/php-simple-proxy
I agree that this isn't completely supported, but here's what I did. You can use a custom view for your action bar (it will display between your icon and your action items). I'm using a custom view and I have the native title disabled. All of my activities inherit from a single activity, which has this code in onCreate:
this.getActionBar().setDisplayShowCustomEnabled(true);
this.getActionBar().setDisplayShowTitleEnabled(false);
LayoutInflater inflator = LayoutInflater.from(this);
View v = inflator.inflate(R.layout.titleview, null);
//if you need to customize anything else about the text, do it here.
//I'm using a custom TextView with a custom font in my layout xml so all I need to do is set title
((TextView)v.findViewById(R.id.title)).setText(this.getTitle());
//assign the view to the actionbar
this.getActionBar().setCustomView(v);
And my layout xml (R.layout.titleview in the code above) looks like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/transparent" >
<com.your.package.CustomTextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:textSize="20dp"
android:maxLines="1"
android:ellipsize="end"
android:text="" />
</RelativeLayout>
I use this command.
kubectl -n <namespace> logs -f deployment/<app-name> --all-containers=true --since=10m
So it seems that CocoaPods didn't set the Configurations for my Project. They need to be based on the Pods.xcconfig
which is found in the Pods/Target Support Files/Pods
. To get this to work I had to do the following:
I then had another build error which may or may not have been related. The path to the shell script defined in the Copy Pods Resources
was incorrect.
"${SRCROOT}/Pods/Pods-resources.sh"
Resolved incorrectly. It seemed that SRCROOT was adding an extra dir that didn't exist into the path. So I hard coded the path to the Project folder.
This allowed me to build.
Why is it that so many things that are supposed to save you time end up eating it up?

You can use Localstorage
1- Add dependency to pubspec.yaml
(Change the version based on the last)
dependencies:
...
localstorage: ^3.0.0
2- Then run the following command
flutter packages get
3- import the localstorage :
import 'package:localstorage/localstorage.dart';
4- create an instance
class MainApp extends StatelessWidget {
final LocalStorage storage = new LocalStorage('localstorage_app');
...
}
Add item to lcoalstorage :
void addItemsToLocalStorage() {
storage.setItem('name', 'Abolfazl');
storage.setItem('family', 'Roshanzamir');
final info = json.encode({'name': 'Darush', 'family': 'Roshanzami'});
storage.setItem('info', info);
}
Get an item from lcoalstorage:
void getitemFromLocalStorage() {
final name = storage.getItem('name'); // Abolfazl
final family = storage.getItem('family'); // Roshanzamir
Map<String, dynamic> info = json.decode(storage.getItem('info'));
final info_name=info['name'];
final info_family=info['family'];
}
Delete an item from localstorage :
void removeItemFromLocalStorage() {
storage.deleteItem('name');
storage.deleteItem('family');
storage.deleteItem('info');
}
According to the CI docs (CodeIgniter Email Library)...
If you prefer not to set preferences using the above method, you can instead put them into a config file. Simply create a new file called the email.php, add the $config array in that file. Then save the file at config/email.php and it will be used automatically. You will NOT need to use the $this->email->initialize() function if you save your preferences in a config file.
I was able to get this to work by putting all the settings into application/config/email.php.
$config['useragent'] = 'CodeIgniter';
$config['protocol'] = 'smtp';
//$config['mailpath'] = '/usr/sbin/sendmail';
$config['smtp_host'] = 'ssl://smtp.googlemail.com';
$config['smtp_user'] = '[email protected]';
$config['smtp_pass'] = 'YOURPASSWORDHERE';
$config['smtp_port'] = 465;
$config['smtp_timeout'] = 5;
$config['wordwrap'] = TRUE;
$config['wrapchars'] = 76;
$config['mailtype'] = 'html';
$config['charset'] = 'utf-8';
$config['validate'] = FALSE;
$config['priority'] = 3;
$config['crlf'] = "\r\n";
$config['newline'] = "\r\n";
$config['bcc_batch_mode'] = FALSE;
$config['bcc_batch_size'] = 200;
Then, in one of the controller methods I have something like:
$this->load->library('email'); // Note: no $config param needed
$this->email->from('[email protected]', '[email protected]');
$this->email->to('[email protected]');
$this->email->subject('Test email from CI and Gmail');
$this->email->message('This is a test.');
$this->email->send();
Also, as Cerebro wrote, I had to uncomment out this line in my php.ini file and restart PHP:

I must add :
I had the same problem, it was coming from the fact that my teammate had a different version of cordova, and commited plugins on the repo with his version.
For all cordova plugins, I had to :
cordova plugin rm <plugin-name>
cordova plugin add <plugin-name>
And ask my teammate to update his cordova to match my version
No it's not a bug. Have a look at the Loose comparisons with == table (second table), which shows the result of comparing each value in the first column with the values in the other columns:
TRUE FALSE 1 0 -1 "1" "0" "-1" NULL array() "php" ""
[...]
"" FALSE TRUE FALSE TRUE FALSE FALSE FALSE FALSE TRUE FALSE FALSE TRUE
There you can see that an empty string ""
compared with false
, 0
, NULL
or ""
will yield true.
You might want to use is_null
[docs] instead, or strict comparison (third table).
For my case, it was my code calling System.exit(0).
Here is the extract about it from te documentation:
Surefire does not support tests or any referenced libraries calling System.exit() at any time. If they do so, they are incompatible with Surefire and you should probably file an issue with the library/vendor.
It's part of the .NET Framework 4.7

Ended up writing something of my own based on UUID.java implementation. Note that I'm not generating a UUID, instead just a random 32 bytes hex string in the most efficient way I could think of.
import java.security.SecureRandom;
import java.util.UUID;
public class RandomUtil {
// Maxim: Copied from UUID implementation :)
private static volatile SecureRandom numberGenerator = null;
private static final long MSB = 0x8000000000000000L;
public static String unique() {
SecureRandom ng = numberGenerator;
if (ng == null) {
numberGenerator = ng = new SecureRandom();
}
return Long.toHexString(MSB | ng.nextLong()) + Long.toHexString(MSB | ng.nextLong());
}
}
RandomUtil.unique()
Some of the inputs I've tested to make sure it's working:
public static void main(String[] args) {
System.out.println(UUID.randomUUID().toString());
System.out.println(RandomUtil.unique());
System.out.println();
System.out.println(Long.toHexString(0x8000000000000000L |21));
System.out.println(Long.toBinaryString(0x8000000000000000L |21));
System.out.println(Long.toHexString(Long.MAX_VALUE + 1));
}
I just tested this, it works sweet and doesn't require a lookup table. rand_alnum() sort of forces out alphanumerics but because it selects 62 out of a possible 256 chars it isn't a big deal.
#include <cstdlib> // for rand()
#include <cctype> // for isalnum()
#include <algorithm> // for back_inserter
#include <string>
char
rand_alnum()
{
char c;
while (!std::isalnum(c = static_cast<char>(std::rand())))
;
return c;
}
std::string
rand_alnum_str (std::string::size_type sz)
{
std::string s;
s.reserve (sz);
generate_n (std::back_inserter(s), sz, rand_alnum);
return s;
}
After looking at sp_who, Oracle does not have that ability per se. Oracle has at least 8 processes running which run the db. Like RMON etc.
You can ask the DB which queries are running as that just a table query. Look at the V$ tables.
Quick Example:
SELECT sid,
opname,
sofar,
totalwork,
units,
elapsed_seconds,
time_remaining
FROM v$session_longops
WHERE sofar != totalwork;
Check this:
<select class="form-control" id="department" name="department" type="text">
<option value="medical-furniture" @if($list->department == "medical-furniture") selected @endif>Medical furniture</option>
<option value="medical-table" @if($list->department == "medical-table") selected @endif>Medical table</option>
<option value="service" @if($list->department == "service") selected @endif>Service</option>
</select>
No, these defines are compiler dependent. What you can do, use your own set of defines, and set them on the Makefile. See this thread for more info.
Just throwing this out there...Can't you just do:
Collections.sort(myarrayList);
It's been awhile though...
well check out the eclipse distro easyeclipse at EasyEclipse. it has Visual editor project already added as a plugin, so no hassles of eclipse version compatibility.Plus the eclipse help section has a tutorial on VE.
On newer versions of yum, this information is stored in the "yumdb" when the package is installed. This is the only 100% accurate way to get the information, and you can use:
yumdb search from_repo repoid
(or repoquery and grep -- don't grep yum output). However the command "find-repos-of-install" was part of yum-utils for a while which did the best guess without that information:
http://james.fedorapeople.org/yum/commands/find-repos-of-install.py
As floyd said, a lot of repos. include a unique "dist" tag in their release, and you can look for that ... however from what you said, I guess that isn't the case for you?
Your code doesn't work for binary files because they can't be cast to strings in the data event handler. If you need to manipulate binary files you'll need to use a buffer. Sorry, I do not have an example of using a buffer because in my case I needed to manipulate HTML files. I just check the content type and then for text/html files update them as needed:
app.get('/*', function(clientRequest, clientResponse) {
var options = {
hostname: 'google.com',
port: 80,
path: clientRequest.url,
method: 'GET'
};
var googleRequest = http.request(options, function(googleResponse) {
var body = '';
if (String(googleResponse.headers['content-type']).indexOf('text/html') !== -1) {
googleResponse.on('data', function(chunk) {
body += chunk;
});
googleResponse.on('end', function() {
// Make changes to HTML files when they're done being read.
body = body.replace(/google.com/gi, host + ':' + port);
body = body.replace(
/<\/body>/,
'<script src="http://localhost:3000/new-script.js" type="text/javascript"></script></body>'
);
clientResponse.writeHead(googleResponse.statusCode, googleResponse.headers);
clientResponse.end(body);
});
}
else {
googleResponse.pipe(clientResponse, {
end: true
});
}
});
googleRequest.end();
});
I tried the above IIS configuration tricks and loopback registry hack, and I reviewed and recreated app pool permissions and a dozen other things and still wasn't able to get rid of the authentication loop running on my development workstation with IIS Express or IIS 7.5, from a local or remote browsing session. I received four 401.2 status responses and a blank page. The exact same site deployed to my IIS 8.5 staging server works flawlessly.
Finally I noticed markup in the Response Body that was rendered blank by the browser contained the default page for a successful log in. I determined that Custom Error handling for ASP.NET and HTTP for the 401 error was preventing/interfering with Windows Authentication my workstation but not the staging server. I spent several hours fiddling with this, but as soon as I removed custom handling for just the 401 error, the workstation was back to normal. I present this as yet one another way to shoot your own foot.

For unix, combining just git
and the built-in diff
:
git show HEAD:path/to/file | diff -y - path/to/file
Of course, you can replace HEAD with any other git reference, and you probably want to add something like -W 170
to the diff command.
This assumes that you are just comparing your directory contents with a past commit. Comparing between two commits is more complex. If your shell is bash
you can use "process substitution":
diff -y -W 170 <(git show REF1:path/to/file) <(git show REF2:path/to/file)
where REF1
and REF2
are git references – tags, branches or hashes.
Hope below answer in this link will help, Multiple Value Filter

If your repo have 2FA enabled. Highly suggest to use the app provided by github.com Here is the link: https://desktop.github.com/
After you downloaded it and installed it. Follow the withard, the app will ask you to provide the one time password for login. Once you filled in the one time password, you could see your repo/projects now.
Modifying each element while iterating a list is fine, as long as you do not change add/remove elements to list.
You can use list comprehension:
l = ['a', ' list', 'of ', ' string ']
l = [item.strip() for item in l]
or just do the C-style
for loop:
for index, item in enumerate(l):
l[index] = item.strip()
It's caused by n % x
where x = 0
in the first loop iteration. You can't calculate a modulus with respect to 0.
chart.series[0].setData(data,true);
The setData
method itself will call the redraw method
Try to clean the HTML first using this function:
$html = htmlspecialchars($html);
Special chars are usually represented differently in HTML and it might be confusing for the compiler. Like &
becomes &
.
Basically, the difference between the two is that one is written in the old way, while the other is written in the modern way. Personally, I prefer the modern script using the inner, left, outer, right definitions because they are more explanatory and makes the code more readable.
When dealing with inner joins there is no real difference in readability neither, however, it may get complicated when dealing with left and right joins as in the older method you would get something like this:
SELECT *
FROM table a, table b
WHERE a.id = b.id (+);
The above is the old way how a left join is written as opposed to the following:
SELECT *
FROM table a
LEFT JOIN table b ON a.id = b.id;
As you can visually see, the modern way of how the script is written makes the query more readable. (By the way same goes for right joins and a little more complicated for outer joins).
Going back to the boiler plate, it doesn't make a difference to the SQL compiler how the query is written as it handles them in the same way. I've seen a mix of both in Oracle databases which have had many people writing into it, both elder and younger ones. Again, it boils down to how readable the script is and the team you are developing with.
You're missing an ending anchor.
if(Regex.IsMatch(myString, "^[A-Za-z]{2}[0-9]{2}\z")) {
// ...
}
EDIT: If you can have anything between an initial 2 letters and a final 2 numbers:
if(Regex.IsMatch(myString, @"^[A-Za-z]{2}.*\d{2}\z")) {
// ...
}
You can't do what I think you're asking to do.
The only privileges you can grant on procedures are EXECUTE and DEBUG.
If you want to allow user B to create a procedure in user A schema, then user B must have the CREATE ANY PROCEDURE privilege. ALTER ANY PROCEDURE and DROP ANY PROCEDURE are the other applicable privileges required to alter or drop user A procedures for user B. All are wide ranging privileges, as it doesn't restrict user B to any particular schema. User B should be highly trusted if granted these privileges.
EDIT:
As Justin mentioned, the way to give execution rights to A for a procedure owned by B:
GRANT EXECUTE ON b.procedure_name TO a;
After working on this for several hours what worked for me was go to /etc/mysql/ and edit the my.cnf file. Add the following
[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
In addition to Windows Task Scheduler you also have 'at' on Windows. I'm not sure how it differs from Task Scheduler besides the fact that it has a command line interface.
The syntax for creating a new table is
CREATE TABLE new_table
AS
SELECT *
FROM old_table
This will create a new table named new_table
with whatever columns are in old_table
and copy the data over. It will not replicate the constraints on the table, it won't replicate the storage attributes, and it won't replicate any triggers defined on the table.
SELECT INTO
is used in PL/SQL when you want to fetch data from a table into a local variable in your PL/SQL block.
The closest I have been able to find is called 3taps. 3taps was sued by Craigslist with the result that "access to public data on a public website can be selectively censored by blacklisting certain viewers (i.e. competitors)", and thus states that "3taps will therefore access the very same data exclusively from public sources that retain open and equal access rights to public data".
You can absolutely do that, just remove the @RequestParam
annotation, Spring will cleanly bind your request parameters to your class instance:
public @ResponseBody List<MyObject> myAction(
@RequestParam(value = "page", required = false) int page,
MyObject myObject)
How about treat the external script as a Java class? Based on this article: https://www.jmdawson.net/blog/2014/08/18/using-functions-from-one-groovy-script-in-another/
getThing.groovy The external script
def getThingList() {
return ["thing","thin2","thing3"]
}
printThing.groovy The main script
thing = new getThing() // new the class which represents the external script
println thing.getThingList()
Result
$ groovy printThing.groovy
[thing, thin2, thing3]

The iPhone 6+ renders internally using @3x assets at a virtual resolution of 2208×1242 (with 736x414 points), then samples that down for display. The same as using a scaled resolution on a Retina MacBook — it lets them hit an integral multiple for pixel assets while still having e.g. 12 pt text look the same size on the screen.
So, yes, the launch screens need to be that size.
The 6, the 5s, the 5, the 4s and the 4 are all 326 pixels per inch, and use @2x assets to stick to the approximately 160 points per inch of all previous devices.
The 6+ is 401 pixels per inch. So it'd hypothetically need roughly @2.46x assets. Instead Apple uses @3x assets and scales the complete output down to about 84% of its natural size.
In practice Apple has decided to go with more like 87%, turning the 1080 into 1242. No doubt that was to find something as close as possible to 84% that still produced integral sizes in both directions — 1242/1080 = 2208/1920 exactly, whereas if you'd turned the 1080 into, say, 1286, you'd somehow need to render 2286.22 pixels vertically to scale well.
If your DataFrame has values with the same type, you can also set return_counts=True
in numpy.unique().
index, counts = np.unique(df.values,return_counts=True)
np.bincount() could be faster if your values are integers.
Came across this old thread searching for a similar solution myself and found the accepted answer to be using .complete()
method of jquery ajax
. I quote the notice on jquery website here:
The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.
To know the status code
of a ajax response, one can use the following code:
$.ajax( url [, settings ] )
.always(function (jqXHR) {
console.log(jqXHR.status);
});
Works similarily for .done()
and .fail()
this.setState(
{
originId: input.originId,
destinationId: input.destinationId,
radius: input.radius,
search: input.search
},
function() { console.log("setState completed", this.state) }
)
this might be helpful
function get_attribute(){ alert( $(this).attr("data-id") ); }

Take a look at jfxmessagebox (http://en.sourceforge.jp/projects/jfxmessagebox/) if you are looking for very simple dialog popups.
Not the most elegant way but this worked for me:
var ms = date.substring(6, date.length - 2);
var newDate = formatDate(ms);
function formatDate(ms) {
var date = new Date(parseInt(ms));
var hour = date.getHours();
var mins = date.getMinutes() + '';
var time = "AM";
// find time
if (hour >= 12) {
time = "PM";
}
// fix hours format
if (hour > 12) {
hour -= 12;
}
else if (hour == 0) {
hour = 12;
}
// fix minutes format
if (mins.length == 1) {
mins = "0" + mins;
}
// return formatted date time string
return date.getMonth() + 1 + "/" + date.getDate() + "/" + date.getFullYear() + " " + hour + ":" + mins + " " + time;
}
A litte late answer.
If you want to use a grid like this, you should have a look at Bootstrap, It's relatively easy to install, and it gives you exactly what you are looking for, all wrapped in nice and simple html/css + it works easily for making websites responsive.
When debugging lines of code, here are the usual scenarios:
Eclipse has other advanced debugging features, but these are the basic fundamentals.

There's no reason for the {} command not to work. The semi-obvious questions are:
You are sure that the product is actually installed! There's something in ARP/Programs&Features.
The original install is in fact visible in the current context. It looks as if it might have been a per-user install, and if you are logged in as somebody else now then it won't know about it - you'd need to log in under the same account as the original install.
If the \windows\installer directory was damaged the cached file would be missing, and that's used to do the uninstall.

From the man page, npm start:
runs a package's "start" script, if one was provided. If no version is specified, then it starts the "active" version.
Admittedly, that description is completely unhelpful, and that's all it says. At least it's more documented than socket.io.
Anyhow, what really happens is that npm looks in your package.json file, and if you have something like
"scripts": { "start": "coffee server.coffee" }
then it will do that. If npm can't find your start script, it defaults to:
node server.js
If you want to use a NSArray, you need an Objective-C class to put in it - hence the NSNumber requirement.
That said, Obj-C is still C, so you can use regular C arrays and hold regular ints instead of NSNumbers if you need to.
Check the unsaved values for your primary key/Object ID in your hbm files. If you have automated ID creation by hibernate framework and you are setting the ID somewhere it will throw this error.By default the unsaved value is 0, so if you set the ID to 0 you will see this error.
Suppose I have a model User
User.find(id)
Returns a row where primary key = id. The return type will be User
object.
User.find_by(email:"[email protected]")
Returns first row with matching attribute or email in this case. Return type will be User
object again.
Note :- User.find_by(email: "[email protected]")
is similar to User.find_by_email("[email protected]")
User.where(project_id:1)
Returns all users in users table where attribute matches.
Here return type will be ActiveRecord::Relation
object. ActiveRecord::Relation
class includes Ruby's Enumerable
module so you can use it's object like an array and traverse on it.

An alternative way to code Brettski's answer, with which I otherwise agree entirely, might be
With New FileSystemObject
If .FileExists(yourFilePath) Then
.DeleteFile yourFilepath
End If
End With
Same effect but fewer (well, none at all) variable declarations.
The FileSystemObject is a really useful tool and well worth getting friendly with. Apart from anything else, for text file writing it can actually sometimes be faster than the legacy alternative, which may surprise a few people. (In my experience at least, YMMV).
The function move.CompleteMove(events)
that you use within your class probably doesn't contain a return
statement. So nothing is returned to self.values
(==> None). Use return
in move.CompleteMove(events)
to return whatever you want to store in self.values
and it should work. Hope this helps.
How about Processing for JavaScript? I don't know Processing, but the code always seems rather small for what it can do, it's very visual, and you can run it in a browser.

I have created npm package with intended behaviour as described above in question.
Usage is very simple. For example:
<p id="test" class="test">something</p>
$("#test").hasAttr("class")
returns true.
Works with camelcase too.
Did you try D3.js? Here is a good example.
Alternatively, try using .html
and then wrap with <pre>
tags:
$(someElem).html('this\n has\n newlines').wrap('<pre />');
Use System.DateTime.Now.ToUniversalTime()
. That puts your reading in a known reference-based millisecond format that totally eliminates day change, etc.
Try one of these approaches:
Approach 1)
1- Choose project view
2- Copy your JAR file in app -> lib folder
3- Right click on your JAR file and choose add as library
4- Check it in build.gradle
Approach 2)
1- File -> New -> New Module
2- Import .JAR/.AAR Package
3- Browse your JAR File
4- Finish
5- File -> Project Structure -> Dependencies
6- You should click on + button and then click on Module Dependency
7- You will see your library here
8- choose your library and click ok
9- Then, you will see that your library is added.
For first two approaches, you need a JAR file. You can search http://search.maven.org/ to find JAR files that are related to Android. For example, this is the search result for jdom in this link
Approach 3) Android is using http://jcenter.bintray.com/ as remote library. For example, this is the search result for jdom in the link.
To add a library in this approach, please follow these steps:
1- File -> Project Structure -> Dependencies
2- Click on + button and choose library dependency
3- find your library and select it, then click OK.
I hope it helps.
You need to convert your wildcard expression to a regular expression. For example:
private bool WildcardMatch(String s, String wildcard, bool case_sensitive)
{
// Replace the * with an .* and the ? with a dot. Put ^ at the
// beginning and a $ at the end
String pattern = "^" + Regex.Escape(wildcard).Replace(@"\*", ".*").Replace(@"\?", ".") + "$";
// Now, run the Regex as you already know
Regex regex;
if(case_sensitive)
regex = new Regex(pattern);
else
regex = new Regex(pattern, RegexOptions.IgnoreCase);
return(regex.IsMatch(s));
}
eldNew <- eld[-14,]
See ?"["
for a start ...
For ‘[’-indexing only: ‘i’, ‘j’, ‘...’ can be logical vectors, indicating elements/slices to select. Such vectors are recycled if necessary to match the corresponding extent. ‘i’, ‘j’, ‘...’ can also be negative integers, indicating elements/slices to leave out of the selection.

edit: looking around I notice How to delete the first row of a dataframe in R? , which has the answer ... seems like the title should have popped to your attention if you were looking for answers on SO?
edit 2: I also found How do I delete rows in a data frame? , searching SO for delete row data frame

I had to run this for a column introduced in the later stages of a product, on 10+ tables. So wrote this quick untidy script to generate the alter command for all 'relevant' tables.
SET @NeighboringColumn = '<YOUR COLUMN SHOULD COME AFTER THIS COLUMN>';
SELECT CONCAT("ALTER TABLE `",t.TABLE_NAME,"` CHANGE COLUMN `",COLUMN_NAME,"`
`",COLUMN_NAME,"` ", c.DATA_TYPE, CASE WHEN c.CHARACTER_MAXIMUM_LENGTH IS NOT
NULL THEN CONCAT("(", c.CHARACTER_MAXIMUM_LENGTH, ")") ELSE "" END ," AFTER
`",@NeighboringColumn,"`;")
FROM information_schema.COLUMNS c, information_schema.TABLES t
WHERE c.TABLE_SCHEMA = '<YOUR SCHEMA NAME>'
AND c.COLUMN_NAME = '<COLUMN TO MOVE>'
AND c.TABLE_SCHEMA = t.TABLE_SCHEMA
AND c.TABLE_NAME = t.TABLE_NAME
AND t.TABLE_TYPE = 'BASE TABLE'
AND @NeighboringColumn IN (SELECT COLUMN_NAME
FROM information_schema.COLUMNS c2
WHERE c2.TABLE_NAME = t.TABLE_NAME);
There are lots of answers, but none explained nicely what else can be done. Looking into man pages for dd, it is possible to better specify the size of a file.
This is going to create /tmp/zero_big_data_file.bin filled with zeros, that has size of 20 megabytes :
dd if=/dev/zero of=/tmp/zero_big_data_file.bin bs=1M count=20
This is going to create /tmp/zero_1000bytes_data_file.bin filled with zeros, that has size of 1000 bytes :
dd if=/dev/zero of=/tmp/zero_1000bytes_data_file.bin bs=1kB count=1
or
dd if=/dev/zero of=/tmp/zero_1000bytes_data_file.bin bs=1000 count=1
I think it would look better if we add border-color : transparent as per below:
<hr style="width: 100%; background-color: black; height: 1px; border-color : transparent;" />
If you don't put the border transparent it will be white and i don't think that is good all time.
based to the answer that was given and some improvements this is my approach

Multiple variations of a font family can be declared by changing the font-weight and src property of @font-face rule.
/* Regular Weight */
@font-face {
font-family: Montserrat;
src: url("../fonts/Montserrat-Regular.ttf");
}
/* SemiBold (600) Weight */
@font-face {
font-family: Montserrat;
src: url("../fonts/Montserrat-SemiBold.ttf");
font-weight: 600;
}
/* Bold Weight */
@font-face {
font-family: Montserrat;
src: url("../fonts/Montserrat-Bold.ttf");
font-weight: bold;
}
Declared rules can be used by following
/* Regular */
font-family: Montserrat;
/* Semi Bold */
font-family: Montserrat;
font-weght: 600;
/* Bold */
font-family: Montserrat;
font-weight: bold;
<span style="color:#ffffff; font-size:18px; line-height:35px; font-family: Calibri;">Our Activities </span>
This works for me well:) As it has been already mentioned above "The font tag has been deprecated, at least in XHTML. It always safe to use span tag. font may not give you desire results, at least in my case it didn't.
Something like this:
<?php
$baseUrl = Yii::app()->baseUrl;
$cs = Yii::app()->getClientScript();
$cs->registerScriptFile($baseUrl.'/js/yourscript.js');
$cs->registerCssFile($baseUrl.'/css/yourcss.css');
?>
Functions dealing with text like label
, title
, etc. accept parameters same as matplotlib.text.Text
. For the font size you can use size/fontsize
:
from matplotlib import pyplot as plt
fig = plt.figure()
plt.plot(data)
fig.suptitle('test title', fontsize=20)
plt.xlabel('xlabel', fontsize=18)
plt.ylabel('ylabel', fontsize=16)
fig.savefig('test.jpg')
For globally setting title
and label
sizes, mpl.rcParams
contains axes.titlesize
and axes.labelsize
. (From the page):
axes.titlesize : large # fontsize of the axes title
axes.labelsize : medium # fontsize of the x any y labels
(As far as I can see, there is no way to set x
and y
label sizes separately.)
And I see that axes.titlesize
does not affect suptitle
. I guess, you need to set that manually.
You can see the button "Code" in the attached screenshot, press it and you can get your code in many different languages including PHP cURL
The dateTime.AddDays(-1)
does not subtract that one day from the dateTime
reference. It will return a new instance, with that one day subtracted from the original reference.
DateTime dateTime = DateTime.Now;
DateTime otherDateTime = dateTime.AddDays(-1);
I got this problem with CMake 3.12.1, after an update of Visual Studio 2017. I simply re-ran CMake and it worked.
If you have N
nodes, there are N - 1
directed edges than can lead from it (going to every other node). Therefore, the maximum number of edges is N * (N - 1)

GitHub has deprecated the download support and now supports 'Releases' - https://github.com/blog/1547-release-your-software. To create a release either use the GitHub UI or create an annotated tag (http:// git-scm.com/book/ch2-6.html) and add release notes to it in GitHub. You can then upload binaries, or 'assets', to each release.
Once you have some releases, the GitHub API supports getting information about them, and their assets.
curl -i \
https://api.github.com/repos/:owner/:repo/releases \
-H "Accept: application/vnd.github.manifold-preview+json"
Look for the 'download_count' entry. Theres more info at http://developer.github.com/v3/repos/releases/. This part of the API is still in the preview period ATM so it may change.
GitHub's releases API is now out of the preview period so the 'Accept' header is no longer needed - http://developer.github.com/changes/2013-11-04-releases-api-is-official/
It won't do any harm to continue to add the 'Accept' header though.
Figured it out.
Put a new column to the left of column1 and copy+paste the following formula
=B2=B3
=B3=B4
=B4=B5
... all the way to the bottom (assume column B here is column1 in the original question).
This formula evaluates whether or not the next row is a new value in column1. Deopending on the result, you will have TRUE or FALSE. Copy and Paste these results as values and then swap "FALSE" for nil and "TRUE" for 0.5
Then add that column full of only 0.5's to the column1 which will yield the following table:
newcolumn0 | column1 ("B") | column2 | column3
-----------------------------------------------------
| 1 | small | blue
| 1 | small | orange
1.5 | 1 | small | yellow
| 2 | med | yellow
2.5 | 2 | med | blue
3.5 | 3 | large | green
| 4 | large | green
4.5 | 4 | small | pink
Lastly, copy and paste the values from newcolumn0 right below the values in column1 and then sort the table by column1 and you should have a blank row in between each distinct whole number in column1, with the table something like this:
newcolumn0 | column1 ("B") | column2 | column3
---------------------------------------------------------------
| 1 | small | blue
| 1 | small | orange
1.5 | 1.5 | |
| 1 | small | yellow
| 2 | med | yellow
| 2 | med | blue
2.5 | 2.5 | |
| 3 | large | green
3.5 | 3.5 | |
| 4 | large | green
| 4 | small | pink
4.5 | 4.5 | |
=IF(B3=B2,A2,A2+1)
and copy+paste this formula for the rest of column 2You missed single quote sign:
SELECT *
FROM TABLENAME
WHERE DateTime >= '12/04/2011 12:00:00 AM' AND DateTime <= '25/05/2011 3:53:04 AM'
Also, it is recommended to use ISO8601 format YYYY-MM-DDThh:mm:ss.nnn[ Z ], as this one will not depend on your server's local culture.
SELECT *
FROM TABLENAME
WHERE
DateTime >= '2011-04-12T00:00:00.000' AND
DateTime <= '2011-05-25T03:53:04.000'

EDIT:
I've recently earned a "Good answer" badge for this answer. While my solution is simple and working, the cleanest way to run any program or shell script at login time is described in @trisweb's answer, unless, you want interactivity.
With automator solution you can do things like next:
so, asking to run a script or quit the app, asking passwords, running other automator workflows at login time, conditionally run applications at login time and so on...
Works well for me this (when dir exist):
some_dir="/some/dir with whitespace & other characters/"
if find "`echo "$some_dir"`" -maxdepth 0 -empty | read v; then echo "Empty dir"; fi
With full check:
if [ -d "$some_dir" ]; then
if find "`echo "$some_dir"`" -maxdepth 0 -empty | read v; then echo "Empty dir"; else "Dir is NOT empty" fi
fi
Do this way:-
String newline = System.getProperty("line.separator");

+ "No Item Qty Price Amount" + newline +
+ "1 Bread 1 50.00 50.00" + newline +
+ "____________________________" + newline;

Maybe you'll be able to set the event handlers programmatically, using something like (pseudocode)
sub myhandler(eventsource)
process(eventsource.value)
end sub
for each cell
cell.setEventHandler(myHandler)
But i dont know the syntax for achieving this in VB/VBA, or if is even possible.
I've been using this functionality in node.js, this is my fastest implementation so far:
var nLength = function(n) {
return (Math.log(Math.abs(n)+1) * 0.43429448190325176 | 0) + 1;
}
It should handle positive and negative integers (also in exponential form) and should return the length of integer part in floats.
The following reference should provide some insight into the method: Weisstein, Eric W. "Number Length." From MathWorld--A Wolfram Web Resource.
I believe that some bitwise operation can replace the Math.abs, but jsperf shows that Math.abs works just fine in the majority of js engines.
Update: As noted in the comments, this solution has some issues :(
Update2 (workaround) : I believe that at some point precision issues kick in and the Math.log(...)*0.434...
just behaves unexpectedly. However, if Internet Explorer or Mobile devices are not your cup of tea, you can replace this operation with the Math.log10
function. In Node.js I wrote a quick basic test with the function nLength = (n) => 1 + Math.log10(Math.abs(n) + 1) | 0;
and with Math.log10
it worked as expected. Please note that Math.log10
is not universally supported.
Based on KMier's answer, addresses the comment that this method poses a problem when the field to be padded is not a field, but the outcome of a (possibly complicated) function; the entire function has to be repeated.
Also, this allows for padding a field to the maximum length of its contents.
WITH
cte AS (
SELECT 'foo' AS value_to_be_padded
UNION SELECT 'foobar'
),
cte_max AS (
SELECT MAX(LEN(value_to_be_padded)) AS max_len
)
SELECT
CONCAT(SPACE(max_len - LEN(value_to_be_padded)), value_to_be_padded AS left_padded,
CONCAT(value_to_be_padded, SPACE(max_len - LEN(value_to_be_padded)) AS right_padded;
It turns out, I was using the fetch
method incorrectly.
fetch
expects two parameters: an endpoint to the API, and an optional object which can contain body and headers.
I was wrapping the intended object within a second object, which did not get me any desired result.
Here's how it looks on a high level:
fetch('API_ENDPOINT', OBJECT)
.then(function(res) {
return res.json();
})
.then(function(resJson) {
return resJson;
})
I structured my object as such:
var obj = {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
'Origin': '',
'Host': 'api.producthunt.com'
},
body: JSON.stringify({
'client_id': '(API KEY)',
'client_secret': '(API SECRET)',
'grant_type': 'client_credentials'
})
By default .
(any character) does not match newline characters.
This means you can simply match zero or more of any character then append the end tag.
Find: <li><a href="#">.*
Replace: $0</a>
foreach(preg_split('~[\r\n]+~', $text) as $line){
if(empty($line) or ctype_space($line)) continue; // skip only spaces
// if(!strlen($line = trim($line))) continue; // or trim by force and skip empty
// $line is trimmed and nice here so use it
}
^ this is how you break lines properly, cross-platform compatible with Regexp
:)
var is a variable like any other language. eg.
var price: Double
On the other side, val provides you feature of referencing. eg.
val CONTINENTS = 7
// You refer this to get constant value 7. In this case, val acts as access
// specifier final in Java
and,
val Int.absolute: Int
get() {
return Math.abs(this)
}
// You refer to the newly create 'method' which provides absolute value
// of your integer
println(-5.absolute) // O.P: 5
I guess problem is in width attributes in table and td remove 'px' for example
<table border="0" cellpadding="0" cellspacing="0" width="580px" style="background-color: #0290ba;">
Should be
<table border="0" cellpadding="0" cellspacing="0" width="580" style="background-color: #0290ba;">
list1.equals(list2);
If your list contains a custom Class MyClass, this class must override the equals
function.
class MyClass
{
int field=0;
@0verride
public boolean equals(Object other)
{
if(this==other) return true;
if(other==null || !(other instanceof MyClass)) return false;
return this.field== MyClass.class.cast(other).field;
}
}
Note :if you want to test equals on a java.util.Set rather than a java.util.List
, then your object must override the hashCode
function.
You can define two entry points in your webpack configuration, one for your normal js and the other one for minified js. Then you should output your bundle with its name, and configure UglifyJS plugin to include min.js files. See the example webpack configuration for more details:
module.exports = {
entry: {
'bundle': './src/index.js',
'bundle.min': './src/index.js',
},
output: {
path: path.resolve(__dirname, 'dist'),
filename: "[name].js"
},
plugins: [
new webpack.optimize.UglifyJsPlugin({
include: /\.min\.js$/,
minimize: true
})
]
};
After running webpack, you will get bundle.js and bundle.min.js in your dist folder, no need for extra plugin.

I wrote an npm
package that lets you take an HTML string, including script tags and append it to a container while executing the scripts
Example:
import appendHtml from 'appendhtml';
const html = '<p>Hello</p><script src="some_js_file.js"></script>';
const container = document.getElementById('some-div');
await appendHtml(html, container);
// appendHtml returns a Promise, some_js_file.js is now loaded and executed (note the await)
Find it here: https://www.npmjs.com/package/appendhtml
just wanna add another easy way to do this: If your ImageButton remains its background and you don't set it to null, it will work like a normal button and will show the click animation while clicking exactly like other buttons.The way to hide the background while it is still there:
<ImageButton
android:id="@+id/imageButton2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingBottom="1dp"
android:paddingLeft="1dp"
android:paddingRight="1dp"
android:paddingTop="1dp"
android:src="@drawable/squareicon" />
The paddings won't let the background be visible and make the button act like other buttons.
Facebook uses MQTT instead of HTTP. Push is better than polling. Through HTTP we need to poll the server continuously but via MQTT server pushes the message to clients.

Note that in general, IDE's like Visual Studio will markup a comment in the context of the current language, by selecting the text you wish to turn into a comment, and then using the Ctrl+K Ctrl+C shortcut, or if you are using Resharper / Intelli-J style shortcuts, then Ctrl+/.
Server side Comments:
Razor .cshtml
@* Comment goes here *@

Client Side Comments
HTML Comment
<!-- Comment goes here -->
Javascript Comment
// One line Comment goes Here
/* Multiline comment

As OP mentions, although not displayed on the browser, client side comments will still be generated for the page / script file on the server and downloaded by the page over HTTP, which unless removed (e.g. minification), will waste I/O, and, since the comment can be viewed by the user by viewing the page source or intercepting the traffic with the browser's Dev Tools or a tool like Fiddler or Wireshark, can also pose a security risk, hence the preference to use server side comments on server generated code (like MVC views or .aspx pages).
I had a problem with this. I didn't even create any passwords so I was confused. I googled it and I found out that I should just write root as username and than click GO. I hope it helps.
Whenever you have a known pattern (i.e. you do not use a variable to build a RegExp), use literal regex notation where you only need to use single backslashes to escape special regex metacharacters:
var re = /I like your Apartment\. Could we schedule a viewing\?/g;
^^ ^^
Whenever you need to build a RegExp dynamically, use RegExp
constructor notation where you MUST double backslashes for them to denote a literal backslash:
var questionmark_block = "\\?"; // A literal ?
var initial_subpattern = "I like your Apartment\\. Could we schedule a viewing"; // Note the dot must also be escaped to match a literal dot
var re = new RegExp(initial_subpattern + questionmark_block, "g");
And if you use the String.raw
string literal you may use \
as is (see an example of using a template string literal where you may put variables into the regex pattern):
const questionmark_block = String.raw`\?`; // A literal ?
const initial_subpattern = "I like your Apartment\\. Could we schedule a viewing";
const re = new RegExp(`${initial_subpattern}${questionmark_block}`, 'g'); // Building pattern from two variables
console.log(re); // => /I like your Apartment\. Could we schedule a viewing\?/g

Use the constructor that takes a File
and a boolean
FileOutputStream(File file, boolean append)
and set the boolean to true
. That way, the data you write will be appended to the end of the file, rather than overwriting what was already there.
For a simple and effective PDF viewer, when you require only limited functionality, you can now (iOS 4.0+) use the QuickLook framework:
First, you need to link against QuickLook.framework
and #import
<QuickLook/QuickLook.h>;
Afterwards, in either viewDidLoad
or any of the lazy initialization methods:
QLPreviewController *previewController = [[QLPreviewController alloc] init];
previewController.dataSource = self;
previewController.delegate = self;
previewController.currentPreviewItemIndex = indexPath.row;
[self presentModalViewController:previewController animated:YES];
[previewController release];
You could do something like:
>>> from time import gmtime, strftime
>>> strftime("%a, %d %b %Y %H:%M:%S +0000", gmtime())

As of Fedora 17 it is possible to easily build (cross-compile) binaries for the win32 and win64 targets. This is realized using the mingw-w64 toolchain: http://mingw-w64.sf.net/. Using this toolchain allows you to build binaries for the following programming languages: C, C++, Objective-C, Objective-C++ and Fortran.

Another way is
> length(z[z==TRUE])
[1] 498
While sum(z)
is nice and short, for me length(z[z==TRUE])
is more self explaining. Though, I think with a simple task like this it does not really make a difference...
If it is a large vector, you probably should go with the fastest solution, which is sum(z)
. length(z[z==TRUE])
is about 10x slower and table(z)[TRUE]
is about 200x slower than sum(z)
.
Summing up, sum(z)
is the fastest to type and to execute.

Whenever you want to get the changes from master into your work branch, do a git rebase <remote>/master
. If there are any conflicts. resolve them.
When your work branch is ready, rebase again and then do git push <remote> HEAD:master

Is it possible to add onclick to a div and have it occur if any area of the div is clicked.
Yes … although it should be done with caution. Make sure there is some mechanism that allows keyboard access. Build on things that work
If yes then why is the onclick method not going through to my div.
You are assigning a string where a function is expected.
divTag.onclick = printWorking;
There are nicer ways to assign event handlers though, although older versions of Internet Explorer are sufficiently different that you should use a library to abstract it. There are plenty of very small event libraries and every major library jQuery) has event handling functionality.
That said, now it is 2019, older versions of Internet Explorer no longer exist in practice so you can go direct to addEventListener
You have two options, a PL/SQL block or SQL*Plus bind variables:

If it is just viewing in tree view,One workaround is to use the Explorer in Notepad++ or any other tools.
this works for me:
table {
border-collapse: collapse;
border-style: hidden;
}
table td, table th {
border: 1px solid black;
}
tested in FF 3.6 and Chromium 5.0, IE lacks support; from W3C:
Borders with the 'border-style' of 'hidden' take precedence over all other conflicting borders. Any border with this value suppresses all borders at this location.
You need to look at the explain plans, but unless there is an INDEX or PARTITION on COL_A, you are looking at a FULL TABLE SCAN on both tables.
With that in mind, your first example is throwing out some of the data as it does the FULL TABLE SCAN. That result is being sorted by the UNION, then duplicate data is dropped. This gives you your result set.
In the second example, you are pulling the full contents of both tables. That result is likely to be larger. So the UNION is sorting more data, then dropping the duplicate stuff. Then the filter is being applied to give you the result set you are after.
As a general rule, the earlier you filter away data, the smaller the data set, and the faster you will get your results. As always, your milage may vary.

First of all install git bash and create a repository on git
1) Go to working directory where the file exist which you want to push on remote and create .git folder by
$ git init
2) Add the files in your new local repository.
$ git add .
Note: while you are in same folder make sure you have placed dot after command if you putting path or not putting dot that will create ambiguity
3) Commit the files that you've staged in your local repository.
$ git commit -m "First commit"**
4) after this go to git repository and copy remote URL
$ git remote add origin *remote repository URL
5)
$ git remote -v
Note: this will ask for user.email and user.name just put it as per config
6)
$ git push origin master
this will push whole committed code to FILE.git on repository

Where link is Angular scope variable.

I fixed this error by upgrading the app from .Net Framework 4.5 to 4.6.2.
TLS-1.2 was correctly installed on the server, and older versions like TLS-1.1 were disabled. However, .Net 4.5 does not support TLS-1.2.
Try with this code:
from PIL import Image
Image.fromarray(image).show()
Instead of this goto mess, try using the ampersand & or double ampersand && (conditional to errorlevel 0) as command separators.
I fixed a script snippet with this trick, to summarize, I have three batch files, one which calls the other two after having found which letters the external backup drives have been assigned. I leave the first file on the primary external drive so the calls to its backup routine worked fine, but the calls to the second one required an active drive change. The code below shows how I fixed it:
for %%b in (d e f g h i j k l m n o p q r s t u v w x y z) DO (
if exist "%%b:\Backup.cmd" %%b: & CALL "%%b:\Backup.cmd"
)
If you are not using openjdk, use the below commands to set your keytool.
sudo update-alternatives --install "/usr/bin/keytool" "keytool" "/usr/lib/jvm/java8/jdk1.8.0_251/bin/keytool" 1
AND
sudo update-alternatives --set keytool /usr/lib/jvm/java8/jdk1.8.0_251/bin/keytool
This worked for me!
IF you want Department and highest salary, use
SELECT DeptID, MAX(Salary) FROM EmpDetails GROUP BY DeptID
if you want more columns in employee and department, use
select Department.Name , emp.Name, emp.Salary from Employee emp
inner join (select DeptID, max(salary) [salary] from employee group by DeptID) b
on emp.DeptID = b.DeptID and b.salary = emp.Salary
inner join Department on emp.DeptID = Department.id
order by Department.Name
if use salary in (select max(salary...)) like this, one person have same salary in another department then it will fail.
Do you mean that the date range of the selected rows should not lie fully within the specified date range? In which case:

onResume()
is one of the methods called throughout the activity lifecycle. onResume()
is the counterpart to onPause()
which is called anytime an activity is hidden from view, e.g. if you start a new activity that hides it. onResume()
is called when the activity that was hidden comes back to view on the screen.
You're question asks abou what method is used to restart an activity. onCreate()
is called when the activity is first created. In practice, most activities persist in the background through a series of onPause()
and onResume()
calls. An activity is only really "restarted" by onRestart()
if it is first fully stopped by calling onStop()
and then brought back to life. Thus if you are not actually stopping activities with onStop()
it is most likley you will be using onResume()
.
Read the android doc in the above link to get a better understanding of the relationship between the different lifestyle methods. Regardless of which lifecycle method you end up using the general format is the same. You must override the standard method and include your code, i.e. what you want the activity to do at that point, in the commented section.
@Override
public void onResume(){
//will be executed onResume
}
Resizing the icon is not straightforward. You need to use Java's graphics 2D to scale the image. The first parameter is a Image class which you can easily get from ImageIcon
class. You can use ImageIcon
class to load your image file and then simply call getter method to get the image.
private Image getScaledImage(Image srcImg, int w, int h){
BufferedImage resizedImg = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = resizedImg.createGraphics();
g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g2.drawImage(srcImg, 0, 0, w, h, null);
g2.dispose();
return resizedImg;
}
Another difference between them is the size of the file:
To see the performance benefits of Handlebars.js we must use precompiled templates.

in this section. As does PythonSpeedPerformanceTips in its section on string concatenation, with the following disclaimer:
The accuracy of this section is disputed with respect to later versions of Python. In CPython 2.5, string concatenation is fairly fast, although this may not apply likewise to other Python implementations. See ConcatenationTestCode for a discussion.
I don't know if my solution is best practice, but I achieved loading a bitmap with my desired scaling by using the inDensity
and inTargetDensity
options. inDensity
is 0
initially when not loading a drawable resource, so this approach is for loading non resource images.
The variables imageUri
, maxImageSideLength
and context
are parameters of my method. I posted only the method implementation without the wrapping AsyncTask for clarity.
ContentResolver resolver = context.getContentResolver();
InputStream is;
try {
is = resolver.openInputStream(imageUri);
} catch (FileNotFoundException e) {
Log.e(TAG, "Image not found.", e);
return null;
}
Options opts = new Options();
opts.inJustDecodeBounds = true;
BitmapFactory.decodeStream(is, null, opts);
// scale the image
float maxSideLength = maxImageSideLength;
float scaleFactor = Math.min(maxSideLength / opts.outWidth, maxSideLength / opts.outHeight);
// do not upscale!
if (scaleFactor < 1) {
opts.inDensity = 10000;
opts.inTargetDensity = (int) ((float) opts.inDensity * scaleFactor);
}
opts.inJustDecodeBounds = false;
try {
is.close();
} catch (IOException e) {
// ignore
}
try {
is = resolver.openInputStream(imageUri);
} catch (FileNotFoundException e) {
Log.e(TAG, "Image not found.", e);
return null;
}
Bitmap bitmap = BitmapFactory.decodeStream(is, null, opts);
try {
is.close();
} catch (IOException e) {
// ignore
}
return bitmap;
I ran into this same problem these days and maybe some more detail might be helpful to somebody else.
I was looking some security guidelines for REST APIs and crossed a very intriguing issue with json arrays. Check the link for details, but basically, you should wrap them within an Object as we already saw in this post question.
So, instead of:
[
{
"name": "order1"
},
{
"name": "order2"
}
]
It's advisable that we always do:
{
"data": [
{
"name": "order1"
},
{
"name": "order2"
}
]
}
This is pretty straight-forward when you doing a GET, but might give you some trouble if, instead, your trying to POST/PUT the very same json.
In my case, I had more than one GET that was a List and more than one POST/PUT that would receive the very same json.
So what I end up doing was to use a very simple Wrapper object for a List:
public class Wrapper<T> {
private List<T> data;
public Wrapper() {}
public Wrapper(List<T> data) {
this.data = data;
}
public List<T> getData() {
return data;
}
public void setData(List<T> data) {
this.data = data;
}
}
Serialization of my lists were made with a @ControllerAdvice:
@ControllerAdvice
public class JSONResponseWrapper implements ResponseBodyAdvice<Object> {
@Override
public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {
return true;
}
@Override
@SuppressWarnings("unchecked")
public Object beforeBodyWrite(Object body, MethodParameter returnType, MediaType selectedContentType, Class<? extends HttpMessageConverter<?>> selectedConverterType, ServerHttpRequest request, ServerHttpResponse response) {
if (body instanceof List) {
return new Wrapper<>((List<Object>) body);
}
else if (body instanceof Map) {
return Collections.singletonMap("data", body);
}
return body;
}
}
So, all the Lists and Maps where wrapped over a data object as below:
{
"data": [
{...}
]
}
Deserialization was still default, just using de Wrapper Object:
@PostMapping("/resource")
public ResponseEntity<Void> setResources(@RequestBody Wrapper<ResourceDTO> wrappedResources) {
List<ResourceDTO> resources = wrappedResources.getData();
// your code here
return ResponseEntity
.ok()
.build();
}
That was it! Hope it helps someone.

As many have suggested, JRE v1.7 and above has File.toPath();
File yourFile = ...;
Path yourPath = yourFile.toPath();

File yourFile = ...;
Path yourPath = FileSystems.getDefault().getPath(yourFile.getPath());

It doesn't work because Date - Date
relies on exactly the kind of type coercion TypeScript is designed to prevent.
There is a workaround this using the +
prefix:
var t = Date.now() - +(new Date("2013-02-20T12:01:04.753Z");
Or, if you prefer not to use Date.now()
:
var t = +(new Date()) - +(new Date("2013-02-20T12:01:04.753Z"));
Or see Siddharth Singh's answer, below, for a more elegant solution using valueOf()
I'd go for regexp_replace, although I'm not 100% sure this is usable in PL/SQL
my_value := regexp_replace(my_value, '[[:space:]]*','');
OK, after 2 years it's finally time to correct the syntax:
SELECT t1.value, t2.value
FROM MyTable t1
JOIN MyTable t2
ON t1.id = t2.id
WHERE t1.id = @id
AND t1.status = @status1
AND t2.status = @status2
There's a very basic reason: Constructors are effectively static functions, and in C++ no static function can be virtual.
If you have much experience with C++, you know all about the difference between static & member functions. Static functions are associated with the CLASS, not the objects (instances), so they don't see a "this" pointer. Only member functions can be virtual, because the vtable- the hidden table of function pointers that makes 'virtual' work- is really a data member of each object.
Now, what is the constructor's job? It is in the name- a "T" constructor initializes T objects as they're allocated. This automatically precludes it being a member function! An object has to EXIST before it has a "this" pointer and thus a vtable. That means that even if the language treated constructors as ordinary functions (it doesn't, for related reasons I won't get into), they'd have to be static member functions.
A great way to see this is to look at the "Factory" pattern, especially factory functions. They do what you're after, and you'll notice that if class T has a factory method, it is ALWAYS STATIC. It has to be.
Try Ehcache? It allows you to plug in your own caching expiry algorithms so you could control your peek functionality.

In my case it was Avast Antivirus interfering with the connection. Actions to disable this feature: Avast -> Settings-> Components -> Mail Shield (Customize) -> SSL scanning -> uncheck "Scan SSL connections".
Here is another (more complex) way of getting either the filename or extension, first use the rev
command to invert the file path, cut from the first .
and then invert the file path again, like this:
filename=`rev <<< "$1" | cut -d"." -f2- | rev`
fileext=`rev <<< "$1" | cut -d"." -f1 | rev`
If you want to get the strings separated by the ,
you can use
string b = a.Split(',')[0];
Another way to do this, although equally unsatisfying is:
s = pd.Series([1,3,0,7,5],index=[0,1,2,3,4])
list(s).index(7)
returns: 3
On time tests using a current dataset I'm working with (consider it random):
[64]: %timeit pd.Index(article_reference_df.asset_id).get_loc('100000003003614')
10000 loops, best of 3: 60.1 µs per loop
In [66]: %timeit article_reference_df.asset_id[article_reference_df.asset_id == '100000003003614'].index[0]
1000 loops, best of 3: 255 µs per loop
In [65]: %timeit list(article_reference_df.asset_id).index('100000003003614')
100000 loops, best of 3: 14.5 µs per loop
You can use:
select to_date(to_char(date_field,'dd/mm/yyyy')) from table
Both these will give you the first child node:
console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);
If you need the first child that is an element node then use:
console.log(parentElement.children[0]);
Edit
Ah, I see your problem now; parentElement
is an array.
If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0]
to dearray (yes, I made that word up) the element:
var parentElement = document.getElementsByClassName("uniqueClassName")[0];
Delete
operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirementsInsert
for arrays is basically Set
as mentioned in the beginningi think the simplest way is vanilla javascript:
document.onkeyup = function(event) {
if (event.keyCode === 27){
//do something here
}
}
Updated: Changed key => keyCode
A third criteria for making editing faster is the number of keystrokes required. I would say this is more important than your other 2. In vim, almost all operations require fewer keystrokes than any other editor I'm familiar with.
You mention that you are having trouble with cut & paste, but it sounds like you need more experience with general motion commands in vim. yank 3 words: y3w yank from the cursor to the next semi-colon: yf; yank to the next occurrence of your most recent search: yn All of those are much faster than trying to navigate with a mouse while holding down a modifier key. Also, as seen in some of the examples in CMS's response, vim's motion commands are highly optimized for efficient navigation in C and C++ source code.
As to the question 'how do I use vim that makes me more productive?', I hope the answer is: "efficiently".
"Knowing about sites which handles such massive traffic gives lots of pointers for architects etc. to keep in mind certain stuff while designing new sites"
I think you can probably learn a lot from the design of Facebook, just as you can from the design of any successful large software system. However, it seems to me that you should not keep the current design of Facebook in mind when designing new systems.
Why do you want to be able to handle the traffic that Facebook has to handle? Odds are that you will never have to, no matter how talented a programmer you may be. Facebook itself was not designed from the start for such massive scalability, which is perhaps the most important lesson to learn from it.
If you want to learn about a non-trivial software system I can recommend the book "Dissecting a C# Application" about the development of the SharpDevelop IDE. It is out of print, but it is available for free online. The book gives you a glimpse into a real application and provides insights about IDEs which are useful for a programmer.
