Take a look at the JavaDoc for RestTemplate.
There is the corresponding getForObject
methods that are the HTTP GET equivalents of postForObject
, but they doesn't appear to fulfil your requirements of "GET with headers", as there is no way to specify headers on any of the calls.
Looking at the JavaDoc, no method that is HTTP GET specific allows you to also provide header information. There are alternatives though, one of which you have found and are using. The exchange
methods allow you to provide an HttpEntity
object representing the details of the request (including headers). The execute
methods allow you to specify a RequestCallback
from which you can add the headers upon its invocation.
UPDATED
I've updated your demo: http://jsfiddle.net/terryyounghk/QS56z/18/
Also, I've changed two ^=
to *=
. See http://api.jquery.com/category/selectors/
And note the :checked
selector. See http://api.jquery.com/checked-selector/
function createcodes() {
//run through each row
$('.authors-list tr').each(function (i, row) {
// reference all the stuff you need first
var $row = $(row),
$family = $row.find('input[name*="family"]'),
$grade = $row.find('input[name*="grade"]'),
$checkedBoxes = $row.find('input:checked');
$checkedBoxes.each(function (i, checkbox) {
// assuming you layout the elements this way,
// we'll take advantage of .next()
var $checkbox = $(checkbox),
$line = $checkbox.next(),
$size = $line.next();
$line.val(
$family.val() + ' ' + $size.val() + ', ' + $grade.val()
);
});
});
}
JavaScript does not have such declarations. It would be:
var cubes = ...
regardless
But you can do:
for(var i = 0; i < cubes.length; i++)
{
for(var j = 0; j < cubes[i].length; j++)
{
}
}
Note that JavaScript allows jagged arrays, like:
[
[1, 2, 3],
[1, 2, 3, 4]
]
since arrays can contain any type of object, including an array of arbitrary length.
As noted by MDC:
"for..in should not be used to iterate over an Array where index order is important"
If you use your original syntax, there is no guarantee the elements will be visited in numeric order.
I originally came in here to find how to make PyTest
print in VSCode's console while running/debugging the unit test from there. This can be done with the following launch.json
configuration. Given .venv
the virtual environment folder.
"version": "0.2.0",
"configurations": [
{
"name": "PyTest",
"type": "python",
"request": "launch",
"stopOnEntry": false,
"pythonPath": "${config:python.pythonPath}",
"module": "pytest",
"args": [
"-sv"
],
"cwd": "${workspaceRoot}",
"env": {},
"envFile": "${workspaceRoot}/.venv",
"debugOptions": [
"WaitOnAbnormalExit",
"WaitOnNormalExit",
"RedirectOutput"
]
}
]
}
I followed the solution above from Jonas and it worked well until I needed to add a second column. What I found is that when making the columns visible again Oracle does not necessarily set them visible in the order listed in the statement.
To demonstrate this follow Jonas' example above. As he showed, once the steps are complete the table is in the order that you'd expect. Things then break down when you add another column as shown below:
Example (continued from Jonas'):
Add another column which is to be inserted before column C.
ALTER TABLE t ADD (b2 INT);
Use the technique demonstrated above to move the newly added B2 column before column C.
ALTER TABLE t MODIFY (c INVISIBLE, d INVISIBLE, e INVISIBLE);
ALTER TABLE t MODIFY (c VISIBLE, d VISIBLE, e VISIBLE);
DESCRIBE t;
Name
----
A
B
B2
D
E
C
As shown above column C has moved to the end. It seems that the ALTER TABLE statement above processed the columns in the order D, E, C rather than in the order specified in the statement (perhaps in physical table order). To ensure that the column is placed where desired it is necessary to make the columns visible one by one in the desired order.
ALTER TABLE t MODIFY (c INVISIBLE, d INVISIBLE, e INVISIBLE);
ALTER TABLE t MODIFY c VISIBLE;
ALTER TABLE t MODIFY d VISIBLE;
ALTER TABLE t MODIFY e VISIBLE;
DESCRIBE t;
Name
----
A
B
B2
C
D
E
Yes, that is a good example of a useful closure. The call to warnUser creates the calledCount
variable in its scope and returns an anonymous function which is stored in the warnForTamper
variable. Because there is still a closure making use of the calledCount variable, it isn't deleted upon the function's exit, so each call to the warnForTamper()
will increase the scoped variable and alert the value.
The most common issue I see on Stack Overflow is where someone wants to "delay" use of a variable that is increased upon each loop, but because the variable is scoped then each reference to the variable would be after the loop has ended, resulting in the end state of the variable:
for (var i = 0; i < someVar.length; i++)
window.setTimeout(function () {
alert("Value of i was "+i+" when this timer was set" )
}, 10000);
This would result in every alert showing the same value of i
, the value it was increased to when the loop ended. The solution is to create a new closure, a separate scope for the variable. This can be done using an instantly executed anonymous function, which receives the variable and stores its state as an argument:
for (var i = 0; i < someVar.length; i++)
(function (i) {
window.setTimeout(function () {
alert("Value of i was " + i + " when this timer was set")
}, 10000);
})(i);
e.g. you're using php and $filepath contains pdf file path.
so you can write javascript like to to emulate download dialog box.
<script language="javascript">
window.location.href = '<?php echo $filepath; ?>';
</script
Above code sends browser to pdf file by its url "http://www.domain.com/files/filename.pdf". So at last, browser will show download dialog box to where to save this file on your machine.
Not possible, per MSDN:
You can have the same code execute for multiple trigger types, but the syntax does not allow for multiple code blocks in one trigger:
Trigger on an INSERT, UPDATE, or DELETE statement to a table or view (DML Trigger)
CREATE TRIGGER [ schema_name . ]trigger_name ON { table | view } [ WITH <dml_trigger_option> [ ,...n ] ] { FOR | AFTER | INSTEAD OF } { [ INSERT ] [ , ] [ UPDATE ] [ , ] [ DELETE ] } [ NOT FOR REPLICATION ] AS { sql_statement [ ; ] [ ,...n ] | EXTERNAL NAME <method specifier [ ; ] > }
Nicely explained above!
For all those who may suffer like me to get this working in a localized Windows (mine is XP in Slovak), you may try to replace the %
with a !
So:
SET TEXT=Hello World
SET SUBSTRING=!TEXT:~3,5!
ECHO !SUBSTRING!
$('#id-you-want-to-change').attr('id', 'id-you-want-it-to-be');
I had this very same problem; here was my solution:
SCORE_CHOICES = zip( range(1,n), range(1,n) )
score = models.IntegerField(choices=SCORE_CHOICES, blank=True)
This a transparency solution for most browsers including IE x
.transparent {
/* Required for IE 5, 6, 7 */
/* ...or something to trigger hasLayout, like zoom: 1; */
width: 100%;
/* Theoretically for IE 8 & 9 (more valid) */
/* ...but not required as filter works too */
/* should come BEFORE filter */
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
/* This works in IE 8 & 9 too */
/* ... but also 5, 6, 7 */
filter: alpha(opacity=50);
/* Older than Firefox 0.9 */
-moz-opacity:0.5;
/* Safari 1.x (pre WebKit!) */
-khtml-opacity: 0.5;
/* Modern!
/* Firefox 0.9+, Safari 2?, Chrome any?
/* Opera 9+, IE 9+ */
opacity: 0.5;
}
For an activity you can use this approach to specify a subtitle, along with the title, in the manifest.
Manifest:
<activity
android:name=".MyActivity"
android:label="@string/my_title"
android:description="@string/my_subtitle">
</activity>
Activity:
try {
ActivityInfo activityInfo = getPackageManager().getActivityInfo(getComponentName(), PackageManager.GET_META_DATA);
//String title = activityInfo.loadLabel(getPackageManager()).toString();
int descriptionResId = activityInfo.descriptionRes;
if (descriptionResId != 0) {
toolbar.setSubtitle(Utilities.fromHtml(getString(descriptionResId)));
}
}
catch(Exception e) {
Log.e(LOG_TAG, "Could not get description/subtitle from manifest", e);
}
This way you only need to specify the title string once, and you get to specify the subtitle right alongside it.

Lots of working answers already provided but I think we can do a little better by using the below simple method
//set focus to input field
private fun focusHere() {
findViewById<TextView>(R.id.input).requestFocus()
}
in place of input in R.id.input use any other view id to set focus to that view.
Check out Open Sourcing a Python Project the Right Way.
Let me excerpt the project layout part of that excellent article:
When setting up a project, the layout (or directory structure) is important to get right. A sensible layout means that potential contributors don't have to spend forever hunting for a piece of code; file locations are intuitive. Since we're dealing with an existing project, it means you'll probably need to move some stuff around.
Let's start at the top. Most projects have a number of top-level files (like setup.py, README.md, requirements.txt, etc). There are then three directories that every project should have:
- A docs directory containing project documentation
- A directory named with the project's name which stores the actual Python package
- A test directory in one of two places
- Under the package directory containing test code and resources
- As a stand-alone top level directory To get a better sense of how your files should be organized, here's a simplified snapshot of the layout for one of my projects, sandman:
$ pwd
~/code/sandman
$ tree
.
|- LICENSE
|- README.md
|- TODO.md
|- docs
| |-- conf.py
| |-- generated
| |-- index.rst
| |-- installation.rst
| |-- modules.rst
| |-- quickstart.rst
| |-- sandman.rst
|- requirements.txt
|- sandman
| |-- __init__.py
| |-- exception.py
| |-- model.py
| |-- sandman.py
| |-- test
| |-- models.py
| |-- test_sandman.py
|- setup.py
As you can see, there are some top level files, a docs directory (generated is an empty directory where sphinx will put the generated documentation), a sandman directory, and a test directory under sandman.
I feel cls
is the best answer. It hides the UNC message before anyone can see it. I combined it with a @pushd %~dp0
right after so that it would seem like opening the script and map the location in one step, thus preventing further UNC issues.
cls
@pushd %~dp0
:::::::::::::::::::
:: your script code here
:::::::::::::::::::
@popd
Notes:
pushd
will change your working directory to the scripts location in the new mapped drive.
popd
at the end, to clean up the mapped drive.
I think you can always try the Ctrl + Shift + A to find the action/command you need.
Here you can try to press Ctrl + Shift + A and input «test» to find the command.
An extremely simple way to auto-compile upon save is to type the following into the terminal:
tsc main --watch
where main.ts
is your file name.
Note, this will only run as long as this terminal is open, but it's a very simple solution that can be run while you're editing a program.
What is JSON? – How I explained it to my wifeTM
Me: “It’s basically a way of communicating with someone in writing....but with very specific rules.
Wife: yeah....?
Me: In prosaic English, the rules are pretty loose: just like with cage fighting. Not so with JSON. There are many ways of describing something:
• Example 1: Our family has 4 people: You, me and 2 kids.
• Example 2: Our family: you, me, kid1 and kid2.
• Example 3: Family: [ you, me, kid1, kid2]
• Example 4: we got 4 people in our family: mum, dad, kid1 and kid2.
Wife: Why don’t they just use plain English instead?
Me: They would, but remember we’re dealing with computers. A computer is stupid and is not going to be able to understand sentences. So we gotta be really specific when computers are involved otherwise they get confused. Furthermore, JSON is a fairly efficient way of communicating, so most of the irrelevant stuff is cut out, which is pretty hand. If you wanted to communicate our family, to a computer, one way you could do so is like this:
{
"Family": ["Me", "Wife", "Kid1", "Kid2"]
}
……and that is basically JSON. But remember, you MUST obey the JSON grammar rules. If you break those rules, then a computer simply will not understand (i.e. parse) what you are writing.
Wife: So how do I write in Json?
A good way would be to use a json serialiser - which is a library which does the heavy lifting for you.
Summary
JSON is basically a way of communicating data to someone, with very, very specific rules. Using Key Value Pairs and Arrays. This is the concept explained, at this point it is worth reading the specific rules above.
As it says, it is ambiguous. Your array comparison returns a boolean array. Methods any() and all() reduce values over the array (either logical_or or logical_and). Moreover, you probably don't want to check for equality. You should replace your condition with:
np.allclose(A.dot(eig_vec[:,col]), eig_val[col] * eig_vec[:,col])

I found a solution to this also. This page helped me today so, I am re-posting here too.
/** This is the script that will redraw current screen and submit to paypal. */

echo '<img alt="" border="0" src="https://www.sandbox.paypal.com/en_US/i/scr/pixel.gif" width="1" height="1">'."\n" ;
The above code is the code for one button. You press the button and it will redraw the current screen from purchase to pre-approval. At the same time it opens a new window and hands that new window over to PayPal.
Do not forget that a user can paste an invalid text in a TextBox
.
If you want to restrict that, follow the below code:
private void ultraTextEditor1_TextChanged(object sender, EventArgs e)
{
string append="";
foreach (char c in ultraTextEditor1.Text)
{
if ((!Char.IsNumber(c)) && (c != Convert.ToChar(Keys.Back)))
{
}
else
{
append += c;
}
}
ultraTextEditor1.Text = append;
}
There is also a nice web app to see the dependencies in a weighted map kind of view.
For example:
Answers on how to do it using an array are provided here.
However, C# has a very handy thing called System.Collections :)
Collections are fancy alternatives to using an array, though many of them use an array internally.
For example, C# has a collection called List that functions very similar to the PHP array.
using System.Collections.Generic;
// Create a List, and it can only contain integers.
List<int> list = new List<int>();
for (int i = 0; i < 400; i++)
{
list.Add(i);
}
I would like to give you also the idea to disable an <option>
with a given defined value (not innerhtml
). I recommend to it with jQuery
to get the simplest way. See my sample below.
HTML
Status:
<div id="option">
<select class="status">
<option value="hand" selected>Hand</option>
<option value="simple">Typed</option>
<option value="printed">Printed</option>
</select>
</div>
Javascript
The idea here is how to disable Printed
option when current Status
is Hand
var status = $('#option').find('.status');//to get current the selected value
var op = status.find('option');//to get the elements for disable attribute
(status.val() == 'hand')? op[2].disabled = true: op[2].disabled = false;
You may see how it works here:
Before installing Wamp, go to controlpanel=> Adminstrative tools => IIS Manager and turn off the IIS server. Install wamp and everything works fine. When IIS is on it also uses port 80. You can go through a lot of changing the ports and permissions for wamp but I have found this the quickest and easiest method of getting wamp to run successfully.
Give this a try:
SET sql_mode = ''
Community Note: As pointed out in the answers below, this actually clears all the SQL modes currently enabled. That may not necessarily be what you want.
Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.
So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.
Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.
"What does if __name__==“__main__”:
do?" has already been answered.
Having a main()
function allows you to call its functionality if you import
the module. The main (no pun intended) benefit of this (IMHO) is that you can unit test it.
Just in case if .dt doesn't work for you. Trying .DatetimeIndex might help. Hope the code and our test result here help you fix it. Regards,
import pandas as pd
import datetime
df = pd.DataFrame({'Date':['2015-01-01','2015-01-02','2015-01-03'],'Number':[1,2,3]})
df['Day'] = pd.DatetimeIndex(df['Date']).day_name() # week day name
df.head()

method
import requests
requests.get(url).json()
If you need the difference in seconds (i.e.: you're comparing dates with timestamps, and not whole days), you can simply convert two date or timestamp strings in the format 'YYYY-MM-DD HH:MM:SS' (or specify your string date format explicitly) using unix_timestamp(), and then subtract them from each other to get the difference in seconds. (And can then divide by 60.0 to get minutes, or by 3600.0 to get hours, etc.)
Example:
UNIX_TIMESTAMP('2017-12-05 10:01:30') - UNIX_TIMESTAMP('2017-12-05 10:00:00') AS time_diff -- This will return 90 (seconds). Unix_timestamp converts string dates into BIGINTs.
More on what you can do with unix_timestamp() here, including how to convert strings with different date formatting: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF#LanguageManualUDF-DateFunctions

From experience I'll just note that while it is the C++ way to put formerly-static functions into the anonymous namespace, older compilers can sometimes have problems with this. I currently work with a few compilers for our target platforms, and the more modern Linux compiler is fine with placing functions into the anonymous namespace.
But an older compiler running on Solaris, which we are wed to until an unspecified future release, will sometimes accept it, and other times flag it as an error. The error is not what worries me, it's what it might be doing when it accepts it. So until we go modern across the board, we are still using static (usually class-scoped) functions where we'd prefer the anonymous namespace.
According to this helpful list of operators [an operator can be thought of as a mathematical expression] found here, you can tell the batch compiler that you are manipulating variables instead of fixed numbers by using the += operator instead of the + operator.
Hope I Helped!
A different base R alternative would be to first order
by id
and stopSequence
, split
them based on id
and for every id
we select only the first and last index and subset the dataframe using those indices.
df[sapply(with(df, split(order(id, stopSequence), id)), function(x)
c(x[1], x[length(x)])), ]
# id stopId stopSequence
#1 1 a 1
#3 1 c 3
#5 2 b 1
#6 2 c 4
#8 3 b 1
#7 3 a 3
Or similar using by
df[unlist(with(df, by(order(id, stopSequence), id, function(x)
c(x[1], x[length(x)])))), ]
While arbitrary HTML with only a regex is impossible, it's sometimes appropriate to use them for parsing a limited, known set of HTML.
If you have a small set of HTML pages that you want to scrape data from and then stuff into a database, regexes might work fine. For example, I recently wanted to get the names, parties, and districts of Australian federal Representatives, which I got off of the Parliament's web site. This was a limited, one-time job.
Regexes worked just fine for me, and were very fast to set up.
In Python 3, map
returns an iterable object of type map
, and not a subscriptible list, which would allow you to write map[i]
. To force a list result, write
payIntList = list(map(int,payList))
However, in many cases, you can write out your code way nicer by not using indices. For example, with list comprehensions:
payIntList = [pi + 1000 for pi in payList]
for pi in payIntList:
print(pi)
When creating a PWA, a service worker used on an non https server also generates this error.
You can also enter msinfo32
into the command line.
It will bring up all your system information. Then, in the find box, just enter processor
and it will show you your cores and logical processors for each CPU. I found this way to be easiest.

In my case I wanted to remove jsonobject with status as non zero value, so what I did is made a function "removeJsonObject" which takes old json and gives required json and called that function inside the constuctor.
public CommonAdapter(Context context, JSONObject json, String type) {
this.context=context;
this.json= removeJsonObject(json);
this.type=type;
Log.d("CA:", "type:"+type);
}
public JSONObject removeJsonObject(JSONObject jo){
JSONArray ja= null;
JSONArray jsonArray= new JSONArray();
JSONObject jsonObject1=new JSONObject();
try {
ja = jo.getJSONArray("data");
} catch (JSONException e) {
e.printStackTrace();
}
for(int i=0; i<ja.length(); i++){
try {
if(Integer.parseInt(ja.getJSONObject(i).getString("status"))==0)
{
jsonArray.put(ja.getJSONObject(i));
Log.d("jsonarray:", jsonArray.toString());
}
} catch (JSONException e) {
e.printStackTrace();
}
}
try {
jsonObject1.put("data",jsonArray);
Log.d("jsonobject1:", jsonObject1.toString());
return jsonObject1;
} catch (JSONException e) {
e.printStackTrace();
}
return json;
}
Little bit off topic but say i want to remove all 2s from a list. Here's a very elegant way to do that.
void RemoveAll<T>(T item,List<T> list)
{
while(list.Contains(item)) list.Remove(item);
}
With predicate:
void RemoveAll<T>(Func<T,bool> predicate,List<T> list)
{
while(list.Any(predicate)) list.Remove(list.First(predicate));
}
+1 only to encourage you to leave your answer here for learning purposes. You're also right about it being off-topic, but I won't ding you for that because of there is significant value in leaving your examples here, again, strictly for learning purposes. I'm posting this response as an edit because posting it as a series of comments would be unruly.
Though your examples are short & compact, neither is elegant in terms of efficiency; the first is bad at O(n2), the second, absolutely abysmal at O(n3). Algorithmic efficiency of O(n2) is bad and should be avoided whenever possible, especially in general-purpose code; efficiency of O(n3) is horrible and should be avoided in all cases except when you know n will always be very small. Some might fling out their "premature optimization is the root of all evil" battle axes, but they do so naïvely because they do not truly understand the consequences of quadratic growth since they've never coded algorithms that have to process large datasets. As a result, their small-dataset-handling algorithms just run generally slower than they could, and they have no idea that they could run faster. The difference between an efficient algorithm and an inefficient algorithm is often subtle, but the performance difference can be dramatic. The key to understanding the performance of your algorithm is to understand the performance characteristics of the primitives you choose to use.
In your first example, list.Contains()
and Remove()
are both O(n), so a while()
loop with one in the predicate & the other in the body is O(n2); well, technically O(m*n), but it approaches O(n2) as the number of elements being removed (m) approaches the length of the list (n).
Your second example is even worse: O(n3), because for every time you call Remove()
, you also call First(predicate)
, which is also O(n). Think about it: Any(predicate)
loops over the list looking for any element for which predicate()
returns true. Once it finds the first such element, it returns true. In the body of the while()
loop, you then call list.First(predicate)
which loops over the list a second time looking for the same element that had already been found by list.Any(predicate)
. Once First()
has found it, it returns that element which is passed to list.Remove()
, which loops over the list a third time to yet once again find that same element that was previously found by Any()
and First()
, in order to finally remove it. Once removed, the whole process starts over at the beginning with a slightly shorter list, doing all the looping over and over and over again starting at the beginning every time until finally no more elements matching the predicate remain. So the performance of your second example is O(m*m*n), or O(n3) as m approaches n.
Your best bet for removing all items from a list that match some predicate is to use the generic list's own List<T>.RemoveAll(predicate)
method, which is O(n) as long as your predicate is O(1). A for()
loop technique that passes over the list only once, calling list.RemoveAt()
for each element to be removed, may seem to be O(n) since it appears to pass over the loop only once. Such a solution is more efficient than your first example, but only by a constant factor, which in terms of algorithmic efficiency is negligible. Even a for()
loop implementation is O(m*n) since each call to Remove()
is O(n). Since the for()
loop itself is O(n), and it calls Remove()
m times, the for()
loop's growth is O(n2) as m approaches n.
When you use jackson to map from string to your concrete class, especially if you work with generic type. then this issue may happen because of different class loader. i met it one time with below scenarior:
Project B depend on Library A
in Library A:
public class DocSearchResponse<T> {
private T data;
}
it has service to query data from external source, and use jackson to convert to concrete class
public class ServiceA<T>{
@Autowired
private ObjectMapper mapper;
@Autowired
private ClientDocSearch searchClient;
public DocSearchResponse<T> query(Criteria criteria){
String resultInString = searchClient.search(criteria);
return convertJson(resultInString)
}
}
public DocSearchResponse<T> convertJson(String result){
return mapper.readValue(result, new TypeReference<DocSearchResponse<T>>() {});
}
}
in Project B:
public class Account{
private String name;
//come with other attributes
}
and i use ServiceA from library to make query and as well convert data
public class ServiceAImpl extends ServiceA<Account> {
}
and make use of that
public class MakingAccountService {
@Autowired
private ServiceA service;
public void execute(Criteria criteria){
DocSearchResponse<Account> result = service.query(criteria);
Account acc = result.getData(); // java.util.LinkedHashMap cannot be cast to com.testing.models.Account
}
}
it happen because from classloader of LibraryA, jackson can not load Account class, then just override method convertJson
in Project B to let jackson do its job
public class ServiceAImpl extends ServiceA<Account> {
@Override
public DocSearchResponse<T> convertJson(String result){
return mapper.readValue(result, new TypeReference<DocSearchResponse<T>>() {});
}
}
}
You can use this code on view.blade. {{var_dump($animales)}}
You can do something like this to show blank space:
=IF(AND((E2-D2)>0)=TRUE,E2-D2," ")
Inside if
before first comma is condition then result and return value if true
and last in value as blank if condition is false

[Update] As mentioned by @Aftershock in the comments, util.pump

var http = require('http'),
fileSystem = require('fs'),
path = require('path');
http.createServer(function(request, response) {
var filePath = path.join(__dirname, 'myfile.mp3');
var stat = fileSystem.statSync(filePath);
response.writeHead(200, {
'Content-Type': 'audio/mpeg',
'Content-Length': stat.size
});
var readStream = fileSystem.createReadStream(filePath);
// We replaced all the event handlers with a simple call to readStream.pipe()
readStream.pipe(response);
})
.listen(2000);

Since the question I asked has been seen many times I will provide a detailed answer of it. Feel free to modify it if you want to add more correct content.
First a recap on the question: frame, bounds and center and theirs relationships.
Frame A view's frame
(CGRect
) is the position of its rectangle in the superview
's coordinate system. By default it starts at the top left.
Bounds A view's bounds
(CGRect
) expresses a view rectangle in its own coordinate system.
Center A center
is a CGPoint
expressed in terms of the superview
's coordinate system and it determines the position of the exact center point of the view.
Taken from UIView + position these are the relationships (they don't work in code since they are informal equations) among the previous properties:
frame.origin = center - (bounds.size / 2.0)
center = frame.origin + (bounds.size / 2.0)
frame.size = bounds.size
NOTE: These relationships do not apply if views are rotated. For further info, I will suggest you take a look at the following image taken from The Kitchen Drawer based on Stanford CS193p course. Credits goes to @Rhubarb.
Using the frame
allows you to reposition and/or resize a view within its superview
. Usually can be used from a superview
, for example, when you create a specific subview. For example:
// view1 will be positioned at x = 30, y = 20 starting the top left corner of [self view]
// [self view] could be the view managed by a UIViewController
UIView* view1 = [[UIView alloc] initWithFrame:CGRectMake(30.0f, 20.0f, 400.0f, 400.0f)];
view1.backgroundColor = [UIColor redColor];
[[self view] addSubview:view1];
When you need the coordinates to drawing inside a view
you usually refer to bounds
. A typical example could be to draw within a view
a subview as an inset of the first. Drawing the subview requires to know the bounds
of the superview. For example:
UIView* view1 = [[UIView alloc] initWithFrame:CGRectMake(50.0f, 50.0f, 400.0f, 400.0f)];
view1.backgroundColor = [UIColor redColor];
UIView* view2 = [[UIView alloc] initWithFrame:CGRectInset(view1.bounds, 20.0f, 20.0f)];
view2.backgroundColor = [UIColor yellowColor];
[view1 addSubview:view2];
Different behaviours happen when you change the bounds
of a view.
For example, if you change the bounds
size
, the frame
changes (and vice versa). The change happens around the center
of the view. Use the code below and see what happens:
NSLog(@"Old Frame %@", NSStringFromCGRect(view2.frame));
NSLog(@"Old Center %@", NSStringFromCGPoint(view2.center));
CGRect frame = view2.bounds;
frame.size.height += 20.0f;
frame.size.width += 20.0f;
view2.bounds = frame;
NSLog(@"New Frame %@", NSStringFromCGRect(view2.frame));
NSLog(@"New Center %@", NSStringFromCGPoint(view2.center));
Furthermore, if you change bounds
origin
you change the origin
of its internal coordinate system. By default the origin
is at (0.0, 0.0)
(top left corner). For example, if you change the origin
for view1
you can see (comment the previous code if you want) that now the top left corner for view2
touches the view1
one. The motivation is quite simple. You say to view1
that its top left corner now is at the position (20.0, 20.0)
but since view2
's frame
origin
starts from (20.0, 20.0)
, they will coincide.
CGRect frame = view1.bounds;
frame.origin.x += 20.0f;
frame.origin.y += 20.0f;
view1.bounds = frame;
The origin
represents the view
's position within its superview
but describes the position of the bounds
center.
Finally, bounds
and origin
are not related concepts. Both allow to derive the frame
of a view (See previous equations).
View1's case study
Here is what happens when using the following snippet.
UIView* view1 = [[UIView alloc] initWithFrame:CGRectMake(30.0f, 20.0f, 400.0f, 400.0f)];
view1.backgroundColor = [UIColor redColor];
[[self view] addSubview:view1];
NSLog(@"view1's frame is: %@", NSStringFromCGRect([view1 frame]));
NSLog(@"view1's bounds is: %@", NSStringFromCGRect([view1 bounds]));
NSLog(@"view1's center is: %@", NSStringFromCGPoint([view1 center]));
The relative image.
This instead what happens if I change [self view]
bounds like the following.
// previous code here...
CGRect rect = [[self view] bounds];
rect.origin.x += 30.0f;
rect.origin.y += 20.0f;
[[self view] setBounds:rect];
The relative image.
Here you say to [self view]
that its top left corner now is at the position (30.0, 20.0) but since view1
's frame origin starts from (30.0, 20.0), they will coincide.
Additional references (to update with other references if you want)
About clipsToBounds
(source Apple doc)
Setting this value to YES causes subviews to be clipped to the bounds of the receiver. If set to NO, subviews whose frames extend beyond the visible bounds of the receiver are not clipped. The default value is NO.
In other words, if a view's frame
is (0, 0, 100, 100)
and its subview is (90, 90, 30, 30)
, you will see only a part of that subview. The latter won't exceed the bounds of the parent view.
masksToBounds
is equivalent to clipsToBounds
. Instead to a UIView
, this property is applied to a CALayer
. Under the hood, clipsToBounds
calls masksToBounds
. For further references take a look to How is the relation between UIView's clipsToBounds and CALayer's masksToBounds?.
Try This. This will get you the names of all the classes from all the elements of document.
$(document).ready(function() {
var currentHtml="";

var class_name = $(this).attr('class');
if (class_name.match(/\s/g)){
var newClasses= class_name.split(' ');
for (var i = 0; i <= newClasses.length - 1; i++) {
if (currentHtml.indexOf(newClasses[i]) <0) {
currentHtml += "."+newClasses[i]+"<br>{<br><br>}<br>"
}
}
}
else
{
if (currentHtml.indexOf(class_name) <0) {
currentHtml += "."+class_name+"<br>{<br><br>}<br>"
}
}
}
else
{
console.log("none");
}
});
$("#Test").html(currentHtml);
});

One thing to note though, is that the current branch changes to original
. You’re still left in the previous branch after the process, but can easily git checkout original
, because it’s the same state. If you do not want to lose the previous HEAD
, you should note the commit reference and do git branch -f <previous_branch> <commit>
after that.

You can install multiple Java runtimes under Windows (including Windows 7) as long as each is in their own directory.
For example, if you are running Win 7 64-bit, or Win Server 2008 R2, you may install 32-bit JRE in "C:\Program Files (x86)\Java\jre6" and 64-bit JRE in "C:\Program Files\Java\jre6", and perhaps IBM Java 6 in "C:\Program Files (x86)\IBM\Java60\jre".
The Java Control Panel app theoretically has the ability to manage multiple runtimes: Java tab >> View... button
There are tabs for User and System settings. You can add additional runtimes with Add or Find, but once you have finished adding runtimes and hit OK, you have to hit Apply in the main Java tab frame, which is not as obvious as it could be - otherwise your changes will be lost.
If you have multiple versions installed, only the main version will auto-update. I have not found a solution to this apart from the weak workaround of manually updating whenever I see an auto-update, so I'd love to know if anyone has a fix for that.
Most Java IDEs allow you to select any Java runtime on your machine to build against, but if not using an IDE, you can easily manage this using environment variables in a cmd window. Your PATH and the JAVA_HOME variable determine which runtime is used by tools run from the shell. Set the JAVA_HOME to the jre directory you want and put the bin directory into your path (and remove references to other runtimes) - with IBM you may need to add multiple bin directories. This is pretty much all the set up that the default system Java does. You can also set CLASSPATH, ANT_HOME, MAVEN_HOME, etc. to unique values to match your runtime.
Depending on your version ou cannot do it directly, but you could do something hacky like
select top 25 *
from (
select top 75 *
from table
order by field asc
) a
order by field desc
where 'field' is the key.
Using REQUIRES_NEW
is only relevant when the method is invoked from a transactional context; when the method is invoked from a non-transactional context, it will behave exactly as REQUIRED
- it will create a new transaction.
That does not mean that there will only be one single transaction for all your clients - each client will start from a non-transactional context, and as soon as the the request processing will hit a @Transactional
, it will create a new transaction.
So, with that in mind, if using REQUIRES_NEW
makes sense for the semantics of that operation - than I wouldn't worry about performance - this would textbook premature optimization - I would rather stress correctness and data integrity and worry about performance once performance metrics have been collected, and not before.
On rollback - using REQUIRES_NEW
will force the start of a new transaction, and so an exception will rollback that transaction. If there is also another transaction that was executing as well - that will or will not be rolled back depending on if the exception bubbles up the stack or is caught - your choice, based on the specifics of the operations.
Also, for a more in-depth discussion on transactional strategies and rollback, I would recommend: «Transaction strategies: Understanding transaction pitfalls», Mark Richards.
I use iText RUPS(Reading and Updating PDF Syntax) in Linux. Since it's written in Java, it works on Windows, too. You can browse all the objects in PDF file in a tree structure. It can also decode Flate encoded streams on-the-fly to make inspecting easier.
Here is a screenshot:
In [6]: x = -2
In [7]: x
Out[7]: -2
In [8]: abs(x)
Out[8]: 2
Actually abs
will return the absolute value
of any number. Absolute value is always a non-negative number.
Here’s a simple and straightforward answer to your question, (I think). I am using the TSQL2012 sample database and I am returning only even or odd rows based on “employeeID” in the “HR.Employees” table.
USE TSQL2012;
GO
Return only Even numbers of the employeeID:
SELECT *
FROM HR.Employees
WHERE (empid % 2) = 0;
GO
Return only Odd numbers of the employeeID:
SELECT *
FROM HR.Employees
WHERE (empid % 2) = 1;
GO
Hopefully, that’s the answer you were looking for.
While most people have answered the question directly, I wanted to elaborate more on the concept behind it. First, I was drawn to the attention of IME when I created a default Login Activity. It generated some code for me which included the following:
<EditText
android:id="@+id/password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/prompt_password"
android:imeActionId="@+id/login"
android:imeActionLabel="@string/action_sign_in_short"
android:imeOptions="actionUnspecified"
android:inputType="textPassword"
android:maxLines="1"
android:singleLine="true"/>
You should already be familiar with the inputType attribute. This just informs Android the type of text expected such as an email address, password or phone number. The full list of possible values can be found here.
It was, however, the attribute imeOptions="actionUnspecified"
that I didn't understand its purpose. Android allows you to interact with the keyboard that pops up from bottom of screen when text is selected using the InputMethodManager
. On the bottom corner of the keyboard, there is a button, typically it says "Next" or "Done", depending on the current text field. Android allows you to customize this using android:imeOptions
. You can specify a "Send" button or "Next" button. The full list can be found here.
With that, you can then listen for presses on the action button by defining a TextView.OnEditorActionListener
for the EditText
element. As in your example:
editText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
@Override
public boolean onEditorAction(EditText v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
//do here your stuff f
return true;
}
return false;
}
});
Now in my example I had android:imeOptions="actionUnspecified"
attribute. This is useful when you want to try to login a user when they press the enter key. In your Activity, you can detect this tag and then attempt the login:
mPasswordView = (EditText) findViewById(R.id.password);
mPasswordView.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView textView, int id, KeyEvent keyEvent) {
if (id == R.id.login || id == EditorInfo.IME_NULL) {
attemptLogin();
return true;
}
return false;
}
});
I would Recommend to use Global.asax.cs File.
protected void Application_Error(Object sender, EventArgs e)
{
var exception = Server.GetLastError();
if (exception is HttpUnhandledException)
{
Server.Transfer("~/Error.aspx");
}
if (exception != null)
{
Server.Transfer("~/Error.aspx");
}
try
{
// This is to stop a problem where we were seeing "gibberish" in the
// chrome and firefox browsers
HttpApplication app = sender as HttpApplication;
app.Response.Filter = null;
}
catch
{
}
}
You can create variable like this:
x = 10
print(x)
Or this:
globals()['y'] = 100
print(y)
Lets create a new class:
class Foo(object):
def __init__(self):
self.name = 'John'
You can create class instance this way:
instance_name_1 = Foo()
Or this way:
globals()['instance_name_2'] = Foo()
Lets create a function:
def create_new_instance(class_name,instance_name):
globals()[instance_name] = class_name()
print('Class instance '{}' created!'.format(instance_name))
Call a function:
create_new_instance(Foo,'new_instance') #Class instance 'new_instance' created!
print(new_instance.name) #John
Also we can write generator function:
def create_instance(class_name,instance_name):
count = 0
while True:
name = instance_name + str(count)
globals()[name] = class_name()
count += 1
print('Class instance: {}'.format(name))
yield True
generator_instance = create_instance(Foo,'instance_')
for i in range(5):
next(generator_instance)
#out
#Class instance: instance_0
#Class instance: instance_1
#Class instance: instance_2
#Class instance: instance_3
#Class instance: instance_4
print(instance_0.name) #john
print(instance_1.name) #john
print(instance_2.name) #john
print(instance_3.name) #john
print(instance_4.name) #john
#print(instance_5.name) #error.. we only created 5 instances..
next(generator_instance) #Class instance: instance_5
print(instance_5.name) #John Now it works..
I am a pragmatist, so I will try to look at this in terms of costs and benefits.
Note that for any disadvantage I give, I recognize that they are solvable. That's why I don't look at anything as black and white, but rather, costs and benefits.
Advantages
Disadvantages
Again, I recognize that every one of these problems is solvable, at some cost. But there comes a point where you are spending all your time solving problems which you could have just avoided in the first place. It comes back to the benefits and how important they are to you.
In Android 4.4 and above you can remove the need for a user gesture so long as the HTML5 Video component lives in your own WebView
webview.setWebChromeClient(new WebChromeClient());
webview.getSettings().setMediaPlaybackRequiresUserGesture(false);
To get the video to autoplay, you'd still need to add autoplay to the video element:
<video id='video' controls autoplay>
<source src='http://192.xxx.xxx.xx/XXXXVM01.mp4' type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' >
</video>
Yes, although it's full of gotchas, since JPA is a bit peculiar. It's very much worth reading the documentation on injecting JPA EntityManager
and EntityManagerFactory
, without explicit Spring dependencies in your code:
http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/orm.html#orm-jpa
This allows you to either inject the EntityManagerFactory
, or else inject a thread-safe, transactional proxy of an EntityManager
directly. The latter makes for simpler code, but means more Spring plumbing is required.
I had problems installing the 64-bit version of MySQLdb on Windows via Pip (problem compiling sources) [32bit version installed ok]. Managed to install the compiled MySQLdb from the .whl file available from http://www.lfd.uci.edu/~gohlke/pythonlibs/
The .whl file can then be installed via pip as document in https://pip.pypa.io/en/latest/user_guide/#installing-from-wheels
For example if you save in C:/
the you can install via
pip install c:/MySQL_python-1.2.5-cp27-none-win_amd64.whl
Follow-up: if you have a 64bit version of Python installed, then you want to install the 64-bit AMD version of MySQLdb from the link above [i.e. even if you have a Intel processor]. If you instead try and install the 32-bit version, I think you get the unsupported wheel error in comments below.

The first parameter of Html.RadioButtonFor() should be the property name you're using, and the second parameter should be the value of that specific radio button. Then they'll have the same name attribute value and the helper will select the given radio button when/if it matches the property value.
Example:
<div class="editor-field">
<%= Html.RadioButtonFor(m => m.Gender, "M" ) %> Male
<%= Html.RadioButtonFor(m => m.Gender, "F" ) %> Female
</div>
Here's a more specific example:
I made a quick MVC project named "DeleteMeQuestion" (DeleteMe prefix so I know that I can remove it later after I forget about it).
I made the following model:
namespace DeleteMeQuestion.Models
{
public class QuizModel
{
public int ParentQuestionId { get; set; }
public int QuestionId { get; set; }
public string QuestionDisplayText { get; set; }
public List<Response> Responses { get; set; }
[Range(1,999, ErrorMessage = "Please choose a response.")]
public int SelectedResponse { get; set; }
}
public class Response
{
public int ResponseId { get; set; }
public int ChildQuestionId { get; set; }
public string ResponseDisplayText { get; set; }
}
}
There's a simple range validator in the model, just for fun. Next up, I made the following controller:
namespace DeleteMeQuestion.Controllers
{
[HandleError]
public class HomeController : Controller
{
public ActionResult Index(int? id)
{
// TODO: get question to show based on method parameter
var model = GetModel(id);
return View(model);
}
[HttpPost]
public ActionResult Index(int? id, QuizModel model)
{
if (!ModelState.IsValid)
{
var freshModel = GetModel(id);
return View(freshModel);
}
// TODO: save selected answer in database
// TODO: get next question based on selected answer (hard coded to 999 for now)
var nextQuestionId = 999;
return RedirectToAction("Index", "Home", new {id = nextQuestionId});
}
private QuizModel GetModel(int? questionId)
{
// just a stub, in lieu of a database
var model = new QuizModel
{
QuestionDisplayText = questionId.HasValue ? "And so on..." : "What is your favorite color?",
QuestionId = 1,
Responses = new List<Response>
{
new Response
{
ChildQuestionId = 2,
ResponseId = 1,
ResponseDisplayText = "Red"
},
new Response
{
ChildQuestionId = 3,
ResponseId = 2,
ResponseDisplayText = "Blue"
},
new Response
{
ChildQuestionId = 4,
ResponseId = 3,
ResponseDisplayText = "Green"
},
}
};
return model;
}
}
}
Finally, I made the following view that makes use of the model:
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<DeleteMeQuestion.Models.QuizModel>" %>
<asp:Content ContentPlaceHolderID="TitleContent" runat="server">
Home Page
</asp:Content>
<asp:Content ContentPlaceHolderID="MainContent" runat="server">
<% using (Html.BeginForm()) { %>
<div>
<h1><%: Model.QuestionDisplayText %></h1>
<div>
<ul>
<% foreach (var item in Model.Responses) { %>
<li>
<%= Html.RadioButtonFor(m => m.SelectedResponse, item.ResponseId, new {id="Response" + item.ResponseId}) %>
<label for="Response<%: item.ResponseId %>"><%: item.ResponseDisplayText %></label>
</li>
<% } %>
</ul>
<%= Html.ValidationMessageFor(m => m.SelectedResponse) %>
</div>
<input type="submit" value="Submit" />
<% } %>
</asp:Content>
As I understand your context, you have questions with a list of available answers. Each answer will dictate the next question. Hopefully that makes sense from my model and TODO comments.
This gives you the radio buttons with the same name attribute, but different ID attributes.
just to add here...

(such a little thing to miss), so I thought I should share. If it works for some of you please up-vote.
Mr. Curious was curious about this as well. In addition to the #>> '{}'
operator, in 9.6+ one can get the value of a jsonb string with the ->>
operator:
select to_jsonb('Some "text"'::TEXT)->>0;
?column?
-------------
Some "text"
(1 row)
If one has a json value, then the solution is to cast into jsonb first:
select to_json('Some "text"'::TEXT)::jsonb->>0;
?column?
-------------
Some "text"
(1 row)
What you posted literally means "Find any divs that are inside of section divs and are the first child of their parent." The sub contains one tag that matches that description.
It is unclear to me whether you want both children of the main div or not. If so, use this:
div.section > div
If you only want the header, use this:
div.section > div:first-child
Using the >
changes the description to: "Find any divs that are the direct descendents of section divs" which is what you want.
Please note that all major browsers support this method, except IE6. If IE6 support is mission-critical, you will have to add classes to the child divs and use that, instead. Otherwise, it's not worth caring about.
Just an alternative that I came up with to extract an extension, using the posts in this thread with my own small knowledge base that was more familiar to me.
ext="$(rev <<< "$(cut -f "1" -d "." <<< "$(rev <<< "file.docx")")")"
Note: Please advise on my use of quotes; it worked for me but I might be missing something on their proper use (I probably use too many).
You need to pass an array of element to jsx
. The problem is that forEach
does not return anything (i.e it returns undefined
). So it's better to use map
because map
returns an array:
class QuestionSet extends Component {
render(){
<div className="container">
<h1>{this.props.question.text}</h1>
{this.props.question.answers.map((answer, i) => {
console.log("Entered");
// Return the element. Also pass key
return (<Answer key={answer} answer={answer} />)
})}
}
export default QuestionSet;
ReduceByKey reduceByKey(func, [numTasks])
-
Data is combined so that at each partition there should be at least one value for each key. And then shuffle happens and it is sent over the network to some particular executor for some action such as reduce.
GroupByKey - groupByKey([numTasks])
It doesn't merge the values for the key but directly the shuffle process happens and here lot of data gets sent to each partition, almost same as the initial data.
And the merging of values for each key is done after the shuffle. Here lot of data stored on final worker node so resulting in out of memory issue.
AggregateByKey - aggregateByKey(zeroValue)(seqOp, combOp, [numTasks])
It is similar to reduceByKey but you can provide initial values when performing aggregation.
Use of reduceByKey
reduceByKey
can be used when we run on large data set.
reduceByKey
when the input and output value types are of same type
over aggregateByKey
Moreover it recommended not to use groupByKey
and prefer reduceByKey
. For details you can refer here.
You can also refer this question to understand in more detail how reduceByKey
and aggregateByKey
.

As the error states - the database is not open - it was previously shut down, and someone left it in the middle of the startup process. They may either be intentional, or unintentional (i.e., it was supposed to be open, but failed to do so).
Assuming that's nothing wrong with the database itself, you could open it with a simple statement. (Since the question is asked specifically in the context of SQLPlus, kindly remember to put a statement terminator(Semicolon) at the end mandatorily, otherwise, it will result in an error. The semicolon character is a statement terminator. It is a part of the ANSI SQL-92 standard.)

Next, you have to create the .pfx file that you will use to sign your deployments. Open a Command Prompt window, and type the following command:
PVK2PFX –pvk yourprivatekeyfile.pvk –spc yourcertfile.cer –pfx yourpfxfile.pfx –po yourpfxpassword
where:
- pvk - yourprivatekeyfile.pvk is the private key file that you created in step 4.
- spc - yourcertfile.cer is the certificate file you created in step 4.
- pfx - yourpfxfile.pfx is the name of the .pfx file that will be creating.
- po - yourpfxpassword is the password that you want to assign to the .pfx file. You will be prompted for this password when you add the .pfx file to a project in Visual Studio for the first time.
(Optionally (and not for the OP, but for future readers), you can create the .cer and .pvk file from scratch) (you would do this BEFORE the above). Note the mm/dd/yyyy are placeholders for start and end dates. see msdn article for full documentation.
makecert -sv yourprivatekeyfile.pvk -n "CN=My Certificate Name" yourcertfile.cer -b mm/dd/yyyy -e mm/dd/yyyy -r
Framework 4: no need to use StreamWriter:
System.IO.File.WriteAllLines("SavedLists.txt", Lists.verbList);
Don't try to make it hard just follow a simple way
date is a string where your date is saved
String s2=date.substring(0,date.length()-11);
now print the value of s2
.
it will reduce your string length and you will get only date part.
FireFox does not allow to open a local file. But if you want to use this for testing a different image (which is what I just needed to do), you can simply save the whole page locally, and then insert the url(file:///somewhere/file.png) - which works for me.
As many answers are written for the same domains, I'll write how to do this in cross domains.
First, you need to know the Post Message API. We need a messenger to communicate between two windows.
Here's a messenger I created.
/**
* Creates a messenger between two windows
* which have two different domains
*/
class CrossMessenger {
/**
*
* @param {object} otherWindow - window object of the other
* @param {string} targetDomain - domain of the other window
* @param {object} eventHandlers - all the event names and handlers
*/
constructor(otherWindow, targetDomain, eventHandlers = {}) {
this.otherWindow = otherWindow;
this.targetDomain = targetDomain;
this.eventHandlers = eventHandlers;
window.addEventListener("message", (e) => this.receive.call(this, e));
}
post(event, data) {
try {
// data obj should have event name
var json = JSON.stringify({
event,
data
});
this.otherWindow.postMessage(json, this.targetDomain);
} catch (e) {}
}
receive(e) {
var json;
try {
json = JSON.parse(e.data ? e.data : "{}");
} catch (e) {
return;
}
var eventName = json.event,
data = json.data;
if (e.origin !== this.targetDomain)
return;
if (typeof this.eventHandlers[eventName] === "function")
this.eventHandlers[eventName](data);
}
}
Using this in two windows to communicate can solve your problem.
In the main windows,
var msger = new CrossMessenger(iframe.contentWindow, "https://iframe.s.domain");
var cssContent = Array.prototype.map.call(yourCSSElement.sheet.cssRules, css_text).join('\n');
msger.post("cssContent", {
css: cssContent
})
Then, receive the event from the Iframe.
In the Iframe:
var msger = new CrossMessenger(window.parent, "https://parent.window.domain", {
cssContent: (data) => {
var cssElem = document.createElement("style");
cssElem.innerHTML = data.css;
document.head.appendChild(cssElem);
}
})
See the Complete Javascript and Iframes tutorial for more details.
As mentioned before - If you do not need to search for data within the array, you can use serialize - but this is "php only". So I would recommend to use json_decode / json_encode - not only for performance but also for readability and portability (other languages such as javascript can handle json_encoded data).
do url_raw.cast_to_raw()
support in oracle 6
This could be as simple as:
@Column(name = "Some_Column", nullable = false)
but while persisting, the value of "Some_Column"is null, even if "Some_Column" may not be any primary or foreign key.
Here is an answer based on that by Anubis (which is a better approach as it doesn't modify the headers for every request) but which is more equivalent to the code in the original question:
using Newtonsoft.Json;
...
var client = new HttpClient();
var httpRequestMessage = new HttpRequestMessage
{
Method = HttpMethod.Post,
RequestUri = new Uri("https://api.clickatell.com/rest/message"),
Headers = {
{ HttpRequestHeader.Authorization.ToString(), "Bearer xxxxxxxxxxxxxxxxxxx" },
{ HttpRequestHeader.Accept.ToString(), "application/json" },
{ "X-Version", "1" }
},
Content = new StringContent(JsonConvert.SerializeObject(svm))
};
var response = client.SendAsync(httpRequestMessage).Result;
If you're comfortable with numba it allows to create a fast short-circuit (stops as soon as a NaN is found) function:
import numba as nb
import math
@nb.njit
def anynan(array):
array = array.ravel()
for i in range(array.size):
if math.isnan(array[i]):
return True
return False
If there is no NaN
the function might actually be slower than np.min
, I think that's because np.min
uses multiprocessing for large arrays:
import numpy as np
array = np.random.random(2000000)
%timeit anynan(array) # 100 loops, best of 3: 2.21 ms per loop
%timeit np.isnan(array.sum()) # 100 loops, best of 3: 4.45 ms per loop
%timeit np.isnan(array.min()) # 1000 loops, best of 3: 1.64 ms per loop
But in case there is a NaN in the array, especially if it's position is at low indices, then it's much faster:
array = np.random.random(2000000)
array[100] = np.nan
%timeit anynan(array) # 1000000 loops, best of 3: 1.93 µs per loop
%timeit np.isnan(array.sum()) # 100 loops, best of 3: 4.57 ms per loop
%timeit np.isnan(array.min()) # 1000 loops, best of 3: 1.65 ms per loop
Similar results may be achieved with Cython or a C extension, these are a bit more complicated (or easily avaiable as bottleneck.anynan
) but ultimatly do the same as my anynan
function.
Another way to mimic an enum with consistent equality handling (shamelessly adopted from Dave Thomas). Allows open enums (much like symbols) and closed (predefined) enums.
class Enum
def self.new(values = nil)
enum = Class.new do
unless values
def self.const_missing(name)
const_set(name, new(name))
end
end
def initialize(name)
@enum_name = name
end
def to_s
"#{self.class}::#@enum_name"
end
end
if values
enum.instance_eval do
values.each { |e| const_set(e, enum.new(e)) }
end
end
enum
end
end
Genre = Enum.new %w(Gothic Metal) # creates closed enum
Architecture = Enum.new # creates open enum
Genre::Gothic == Genre::Gothic # => true
Genre::Gothic != Architecture::Gothic # => true
You can use following ways to setup Spark:
Though there are various ways to build Spark from Source.
First I tried building Spark source with SBT but that requires hadoop. To avoid those issues, I used pre-built release.
Instead of Source,I downloaded Prebuilt release for hadoop 2.x version and ran it. For this you need to install Scala as prerequisite.
I have collated all steps here :

You might be better asking this on the WiX-users mailing list.
WiX is best used with a firm understanding of what Windows Installer is doing. You might consider getting "The Definitive Guide to Windows Installer".
The action that removes an existing product is the RemoveExistingProducts action. Because the consequences of what it does depends on where it's scheduled - namely, whether a failure causes the old product to be reinstalled, and whether unchanged files are copied again - you have to schedule it yourself.
RemoveExistingProducts
processes <Upgrade>
elements in the current installation, matching the @Id
attribute to the UpgradeCode
(specified in the <Product>
element) of all the installed products on the system. The UpgradeCode
defines a family of related products. Any products which have this UpgradeCode, whose versions fall into the range specified, and where the UpgradeVersion/@OnlyDetect
attribute is no
(or is omitted), will be removed.
The documentation for RemoveExistingProducts
mentions setting the UPGRADINGPRODUCTCODE
property. It means that the uninstall process for the product being removed receives that property, whose value is the Product/@Id
for the product being installed.
If your original installation did not include an UpgradeCode
, you will not be able to use this feature.

This was the good option for SEO because SEO gives the H1 tag high priority, inside the h1 tag should be your site name. Using this method if you search the site name in SEO it will show your site logo as well.
you want to hide the site name OR text please use text-indent in negative value. ex

you can unpack your tuples and get only the first element using a list comprehension:
l = [(1, u'abc'), (2, u'def')]
[f for f, *_ in l]
output:
[1, 2]
this will work no matter how many elements you have in a tuple:
l = [(1, u'abc'), (2, u'def', 2, 4, 5, 6, 7)]
[f for f, *_ in l]
output:
[1, 2]

If you are using iis 7.5.
Just go to IIS Manager, open your website properties.
You will see 'Handler Mappings' section there, just go to that section and Search for 'staticFile'.
Most probably its a last file in the list.
Then Right Click on it and Select 'Revert To Parent'.
I have wasted so many hours while i have faced this first time, anyways this will solve your problem.
You're not actually going out after the values. You would need to gather them like this:
var title = document.getElementById("title").value;
var name = document.getElementById("name").value;
var tickets = document.getElementById("tickets").value;
You could put all of these in one array:
var myArray = [ title, name, tickets ];
Or many arrays:
var titleArr = [ title ];
var nameArr = [ name ];
var ticketsArr = [ tickets ];
Or, if the arrays already exist, you can use their .push()
method to push new values onto it:
var titleArr = [];
function addTitle ( title ) {
titleArr.push( title );
console.log( "Titles: " + titleArr.join(", ") );
}
Your save button doesn't work because you refer to this.form
, however you don't have a form on the page. In order for this to work you would need to have <form>
tags wrapping your fields:
I've made several corrections, and placed the changes on jsbin: http://jsbin.com/ufanep/2/edit
The new form follows:
<form>
<h1>Please enter data</h1>
<input id="title" type="text" />
<input id="name" type="text" />
<input id="tickets" type="text" />
<input type="button" value="Save" onclick="insert()" />
<input type="button" value="Show data" onclick="show()" />
</form>
<div id="display"></div>
There is still some room for improvement, such as removing the onclick
attributes (those bindings should be done via JavaScript, but that's beyond the scope of this question).
I've also made some changes to your JavaScript. I start by creating three empty arrays:
var titles = [];
var names = [];
var tickets = [];
Now that we have these, we'll need references to our input fields.
var titleInput = document.getElementById("title");
var nameInput = document.getElementById("name");
var ticketInput = document.getElementById("tickets");
I'm also getting a reference to our message display box.
var messageBox = document.getElementById("display");
The insert()
function uses the references to each input field to get their value. It then uses the push()
method on the respective arrays to put the current value into the array.
Once it's done, it cals the clearAndShow()
function which is responsible for clearing these fields (making them ready for the next round of input), and showing the combined results of the three arrays.
function insert ( ) {
titles.push( titleInput.value );
names.push( nameInput.value );
tickets.push( ticketInput.value );
clearAndShow();
}
This function, as previously stated, starts by setting the .value
property of each input to an empty string. It then clears out the .innerHTML
of our message box. Lastly, it calls the join()
method on all of our arrays to convert their values into a comma-separated list of values. This resulting string is then passed into the message box.
function clearAndShow () {
titleInput.value = "";
nameInput.value = "";
ticketInput.value = "";
messageBox.innerHTML = "";
messageBox.innerHTML += "Titles: " + titles.join(", ") + "<br/>";
messageBox.innerHTML += "Names: " + names.join(", ") + "<br/>";
messageBox.innerHTML += "Tickets: " + tickets.join(", ");
}

Another way to create an absolute URL to an action:
var relativeUrl = Url.Action("MyAction"); //..or one of the other .Action() overloads
var currentUrl = Request.Url;

The trick for me was not setting the height -- but instead setting the minHeight. This must be applied to the root view of whatever layout your custom adapter is using to render each row.
If you're using jQuery Cookie (https://plugins.jquery.com/cookie/), you can use decimal point or fractions.
As one day is 1
, one minute would be 1 / 1440
(there's 1440 minutes in a day).
So 30 minutes is 30 / 1440 = 0.02083333
.
Final code:
$.cookie("example", "foo", { expires: 30 / 1440, path: '/' });
I've added path: '/'
so that you don't forget that the cookie is set on the current path. If you're on /my-directory/
the cookie is only set for this very directory.
"(string)o" will result in an InvalidCastException as there's no direct cast.
"o as string" will result in s being a null reference, rather than an exception being thrown.
"o.ToString()" isn't a cast of any sort per-se, it's a method that's implemented by object, and thus in one way or another, by every class in .net that "does something" with the instance of the class it's called on and returns a string.
Don't forget that for converting to string, there's also Convert.ToString(someType instanceOfThatType) where someType is one of a set of types, essentially the frameworks base types.

Here's an option that stays as true I could make it to the OP's requirement to be able to switch on type. If you squint hard enough it almost looks like a real switch statement.
The calling code looks like this:
var @switch = this.Switch(new []
{
this.Case<WebControl>(x => { /* WebControl code here */ }),
this.Case<TextBox>(x => { /* TextBox code here */ }),
this.Case<ComboBox>(x => { /* ComboBox code here */ }),
});
@switch(obj);
The x
in each lambda above is strongly-typed. No casting required.
And to make this magic work you need these two methods:
private Action<object> Switch(params Func<object, Action>[] tests)
{
return o =>
{
var @case = tests
.Select(f => f(o))
.FirstOrDefault(a => a != null);
if (@case != null)
{
@case();
}
};
}
private Func<object, Action> Case<T>(Action<T> action)
{
return o => o is T ? (Action)(() => action((T)o)) : (Action)null;
}
Almost brings tears to your eyes, right?

In PHP 7 we can use:
ini_set('magic_quotes_runtime', 0);
instead of set_magic_quotes_runtime(0);
You're getting errors because you're attempting to read post variables that haven't been set, they only get set on form submission. Wrap your php code at the bottom in an
if ($_SERVER['REQUEST_METHOD'] === 'POST') { ... }
Also, your code is ripe for SQL injection. At the very least use mysql_real_escape_string
on the post vars before using them in SQL queries. mysql_real_escape_string
is not good enough for a production site, but should score you extra points in class.
One way to do this with MS Access is with a subquery but it does not have anything like the same functionality:
SELECT a.ID,
a.AText,
(SELECT Count(ID)
FROM table1 b WHERE b.ID <= a.ID
AND b.AText Like "*a*") AS RowNo
FROM Table1 AS a
WHERE a.AText Like "*a*"
ORDER BY a.ID;
What worked for me was:
$('select option').each(function(){$(this).removeAttr('selected');});
Following is my TypeScript code which can be converted easily into JavaScript and you can use
/**
* Convert BASE64 to BLOB
* @param base64Image Pass Base64 image data to convert into the BLOB
*/
private convertBase64ToBlob(base64Image: string) {
// Split into two parts
const parts = base64Image.split(';base64,');
// Hold the content type
const imageType = parts[0].split(':')[1];
// Decode Base64 string
const decodedData = window.atob(parts[1]);
// Create UNIT8ARRAY of size same as row data length
const uInt8Array = new Uint8Array(decodedData.length);
// Insert all character code into uInt8Array
for (let i = 0; i < decodedData.length; ++i) {
uInt8Array[i] = decodedData.charCodeAt(i);
}
// Return BLOB image after conversion
return new Blob([uInt8Array], { type: imageType });
}
g.next()
has been renamed to g.__next__()
. The reason for this is consistency: special methods like __init__()
and __del__()
all have double underscores (or "dunder" in the current vernacular), and .next()
was one of the few exceptions to that rule. This was fixed in Python 3.0. [*]
But instead of calling g.__next__()
, use next(g)
.
[*] There are other special attributes that have gotten this fix; func_name
, is now __name__
, etc.
Try wkhtmltopdf with either one of the following wrappers
django-wkhtmltopdf or python-pdfkit
This worked great for me,supports javascript and css or anything for that matter which a webkit browser supports.

this in an object that you can read, write, overWrite and delete cookies.
var cookie = {
write : function (cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
var expires = "expires="+d.toUTCString();
document.cookie = cname + "=" + cvalue + "; " + expires;
},
read : function (name) {
if (document.cookie.indexOf(name) > -1) {
return document.cookie.split(name)[1].split("; ")[0].substr(1)
} else {
return "";
}
},
delete : function (cname) {
var d = new Date();
d.setTime(d.getTime() - 1000);
var expires = "expires="+d.toUTCString();
document.cookie = cname + "=; " + expires;
}
};
Scenario:
I have master updating and my branch updating, I want my branch to keep track of master with rebasing, to keep all history tracked properly, let's call my branch Mybranch
Solution:
git checkout master
git pull --rebase
git checkout Mybranch
git rebase master
git push -f origin Mybranch
(correction to last stage, in courtesy of Tzachi Cohen, using "-f" forces git to "update history" at server)
now branch should be aligned with master and rebased, also with remote updated, so at git log there are no "behind" or "ahead", just need to remove all local conflict *.orig files to keep folder "clean"
In order to create an Android Wear emulator you need to follow the instructions below:
If your version of Android SDK Tools is lower than 22.6, you must update
Under Android 4.4.2, select Android Wear ARM EABI v7a System Image and install it.
Under Extras, ensure that you have the latest version of the Android Support Library. If an update is available, select Android Support Library. If you're using Android Studio, also select Android Support Repository.
Below is the snapshot of what it should look like:
Then you must check the following in order to create a Wearable AVD:
For the Device, select Android Wear Square or Android Wear Round.
For the Target, select Android 4.4.2 - API Level 19 (or higher, otherwise corresponding system image will not show up.).
For the CPU/ABI, select Android Wear ARM (armeabi-v7a).
For the Skin, select AndroidWearSquare or AndroidWearRound.
Leave all other options set to their defaults and click OK.
Then you are good to go. For more information you can always refer to the developer site.
I looked at several solutions but all failed with scroll and select text being the biggest confusion. Instead of scrolling right I was closing boxes and such.
I just finished my implementation that does it all for me.
https://github.com/webdevelopers-eu/jquery-dna-gestures
It is MIT so do what you want - and yes, it is really simple - 800 bytes minified. You can check it out on my (under-development) site https://cyrex.tech - swiperight on touch-devices should dismiss popup windows.
I think this table is short and usefull:
Supplier () -> x
Consumer x -> ()
Callable () -> x throws ex
Runnable () -> ()
Function x -> y
BiFunction x,y -> z
Predicate x -> boolean
UnaryOperator x1 -> x2
BinaryOperator x1,x2 -> x3
As said on the other answers, the appropriate option for this problem is a Runnable
When you declare
public static <T> void foo(List<T>... bar)
the compiler converts it to
public static <T> void foo(List<T>[] bar)
then to
public static void foo(List[] bar)
The danger then arises that you'll mistakenly assign incorrect values into the list and the compiler will not trigger any error. For example, if T
is a String
then the following code will compile without error but will fail at runtime:
// First, strip away the array type (arrays allow this kind of upcasting)
Object[] objectArray = bar;
// Next, insert an element with an incorrect type into the array
objectArray[0] = Arrays.asList(new Integer(42));
// Finally, try accessing the original array. A runtime error will occur
// (ClassCastException due to a casting from Integer to String)
T firstElement = bar[0].get(0);
If you reviewed the method to ensure that it doesn't contain such vulnerabilities then you can annotate it with @SafeVarargs
to suppress the warning. For interfaces, use @SuppressWarnings("unchecked")
.
If you get this error message:
Varargs method could cause heap pollution from non-reifiable varargs parameter
and you are sure that your usage is safe then you should use @SuppressWarnings("varargs")
instead. See Is @SafeVarargs an appropriate annotation for this method? and https://stackoverflow.com/a/14252221/14731 for a nice explanation of this second kind of error.
References:
you can use this snippet =>
const timerCountDown = async () => {
let date = new Date();
let time = date.getTime() + 122000;
let countDownDate = new Date(time).getTime();
let x = setInterval(async () => {
let now = new Date().getTime();
let distance = countDownDate - now;
let days = Math.floor(distance / (1000 * 60 * 60 * 24));
let hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
let minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
let seconds = Math.floor((distance % (1000 * 60)) / 1000);
if (distance < 1000) {
// ================== Timer Finished
clearInterval(x);
}
}, 1000);
};
I just had the same problem while creating my first Git repository ever. I had a typo in the Git origin remote creation - turns out I didn't capitalize the name of my repository.
git remote add origin [email protected]:Odd-engine
First I removed the old remote using
git remote rm origin
Then I recreated the origin, making sure the name of my origin was typed EXACTLY the same way my origin was spelled.
git remote add origin [email protected]:Odd-Engine
No more error! :)
If you already have a config.json file then the final file should look something like this...
Here registry.myprivate.com
is the one which was giving me problems.
{
"auths": {
"https://index.docker.io/v1/": {
"auth": "xxxxxxxxxxxxxxxxxxxx=="
},
"registry.myprivate.com": {
"auth": "xxxxxxxxxxxxxxxxxxxx="
}
},
"HttpHeaders": {
"User-Agent": "Docker-Client/19.03.8 (linux)"
},
"insecure-registries" : ["registry.myprivate.com"]
}
You can set the "value" property
dateTimePicker1.Value = DateTime.Today;
You can try this:
function search(data,search) {
var obj = [], index=0;
for(var i=0; i<data.length; i++) {
for(key in data[i]){
if(data[i][key].toString().toLowerCase().indexOf(search.toLowerCase())!=-1) {
obj[index] = data[i];
index++;
break;
}
}
return obj;
}
console.log(search(obj.list,'my Name'));
Did you write return true
somewhere? You should have written it, otherwise function returns nothing and program may think that it's false, too.
function isValid(str) {
var iChars = "~`!#$%^&*+=-[]\\\';,/{}|\":<>?";
for (var i = 0; i < str.length; i++) {
if (iChars.indexOf(str.charAt(i)) != -1) {
alert ("File name has special characters ~`!#$%^&*+=-[]\\\';,/{}|\":<>? \nThese are not allowed\n");
return false;
}
}
return true;
}
I tried this in my chrome console and it worked well.
data-target
is used by bootstrap to make your life easier. You (mostly) do not need to write a single line of Javascript to use their pre-made JavaScript components.
The data-target
attribute should contain a CSS selector that points to the HTML Element that will be changed.
<!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
[...]
</div>
In this example, the button has data-target="#myModal"
, if you click on it, <div id="myModal">...</div>
will be modified (in this case faded in).
This happens because #myModal
in CSS selectors points to elements that have an id
attribute with the myModal
value.
Further information about the HTML5 "data-" attribute: https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes
A. Grab file data from the file field
The first thing to do is bind a function to the change event on your file field and a function for grabbing the file data:
// Variable to store your files
var files;
// Add events
$('input[type=file]').on('change', prepareUpload);
// Grab the files and set them to our variable
function prepareUpload(event)
{
files = event.target.files;
}
This saves the file data to a file variable for later use.
B. Handle the file upload on submit
When the form is submitted you need to handle the file upload in its own AJAX request. Add the following binding and function:
$('form').on('submit', uploadFiles);
// Catch the form submit and upload the files
function uploadFiles(event)
{
event.stopPropagation(); // Stop stuff happening
event.preventDefault(); // Totally stop stuff happening
// START A LOADING SPINNER HERE
// Create a formdata object and add the files
var data = new FormData();
$.each(files, function(key, value)
{
data.append(key, value);
});
$.ajax({
url: 'submit.php?files',
type: 'POST',
data: data,
cache: false,
dataType: 'json',
processData: false, // Don't process the files
contentType: false, // Set content type to false as jQuery will tell the server its a query string request
success: function(data, textStatus, jqXHR)
{
if(typeof data.error === 'undefined')
{
// Success so call function to process the form
submitForm(event, data);
}
else
{
// Handle errors here
console.log('ERRORS: ' + data.error);
}
},
error: function(jqXHR, textStatus, errorThrown)
{
// Handle errors here
console.log('ERRORS: ' + textStatus);
// STOP LOADING SPINNER
}
});
}
What this function does is create a new formData object and appends each file to it. It then passes that data as a request to the server. 2 attributes need to be set to false:
C. Upload the files
Quick and dirty php script to upload the files and pass back some info:
<?php // You need to add server side validation and better error handling here
$data = array();
if(isset($_GET['files']))
{
$error = false;
$files = array();
$uploaddir = './uploads/';
foreach($_FILES as $file)
{
if(move_uploaded_file($file['tmp_name'], $uploaddir .basename($file['name'])))
{
$files[] = $uploaddir .$file['name'];
}
else
{
$error = true;
}
}
$data = ($error) ? array('error' => 'There was an error uploading your files') : array('files' => $files);
}
else
{
$data = array('success' => 'Form was submitted', 'formData' => $_POST);
}
echo json_encode($data);
?>
IMP: Don't use this, write your own.
D. Handle the form submit
The success method of the upload function passes the data sent back from the server to the submit function. You can then pass that to the server as part of your post:
function submitForm(event, data)
{
// Create a jQuery object from the form
$form = $(event.target);
// Serialize the form data
var formData = $form.serialize();
// You should sterilise the file names
$.each(data.files, function(key, value)
{
formData = formData + '&filenames[]=' + value;
});
$.ajax({
url: 'submit.php',
type: 'POST',
data: formData,
cache: false,
dataType: 'json',
success: function(data, textStatus, jqXHR)
{
if(typeof data.error === 'undefined')
{
// Success so call function to process the form
console.log('SUCCESS: ' + data.success);
}
else
{
// Handle errors here
console.log('ERRORS: ' + data.error);
}
},
error: function(jqXHR, textStatus, errorThrown)
{
// Handle errors here
console.log('ERRORS: ' + textStatus);
},
complete: function()
{
// STOP LOADING SPINNER
}
});
}
Final note
This script is an example only, you'll need to handle both server and client side validation and some way to notify users that the file upload is happening. I made a project for it on Github if you want to see it working.
Great question and great idea, but in SQL you'll need to do this:
For data type datetime, something like this-
declare @BeginDate datetime = '1/1/2016',
@EndDate datetime = '12/1/2016'
create table #months (dates datetime)
declare @var datetime = @BeginDate
while @var < dateadd(MONTH, +1, @EndDate)
Begin
insert into #months Values(@var)
set @var = Dateadd(MONTH, +1, @var)
end
If all you really want is numbers, do this-
create table #numbas (digit int)
declare @var int = 1 --your starting digit
while @var <= 12 --your ending digit
begin
insert into #numbas Values(@var)
set @var = @var +1
end
This is best plugin with proper documentation and examples
Plus point: you can ask for help in its discussion forum and you will get response within a day from the author itself, really impressive.
let a = $("<a>bfCaptchaEntry</a>");
a.attr("onClick", "function(" + someParameter+ ")");
Model1.belongsTo(Model2, { as: 'alias' })
Model1.findAll({include: [{model: Model2 , as: 'alias' }]},{raw: true}).success(onSuccess).error(onError);
Add in activity
requestWindowFeature(Window.FEATURE_NO_TITLE);
and add your style.xml
file with the following two lines:
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
for java
driver.findelement(By.id('foo').clear();
or
webElement.clear();
If this element is a text entry element, this will clear the value.
You can use the ternary operator easily:
{{ $usersType ? $usersType : '' }}
I am changing your id to current-month (having no space)
alert($('#current-month').attr('month'));
alert($('#current-month').attr('year'));
First create an array of objects,
var arr = {'name': []};
Next, push the value to the object.
var val = 2;
arr['name'].push(val);
To read from it:
var val = arr.name[0];
User: Access to resource of the database. Like a key to enter a house.
Schema: Collection of information about database objects. Like Index in your book which contains the short information about the chapter.
Also consider Int16. If you need to store an Integer in memory in your application and you are concerned about the amount of memory used, then you could go with Int16 since it uses less memeory and has a smaller min/max range than Int32 (which is what int is.)

Wes McKinney (pandas' author) in Python for Data Analysis provides the following recipe:
groups = dict(list(gb))
which returns a dictionary whose keys are your group labels and whose values are DataFrames, i.e.
groups['foo']
will yield what you are looking for:
A B C
0 foo 1.624345 5
2 foo -0.528172 11
4 foo 0.865408 14
Select the folder containing the package tree of these classes, right-click and choose "Mark Directory as -> Source Root"
//Element[@attribute1="abc" and @attribute2="xyz" and .="Data"]
The reason why I add this answer is that I want to explain the relationship of .
and text()
.
The first thing is when using []
, there are only two types of data:
[number]
to select a node from node-set[bool]
to filter a node-set from node-setIn this case, the value is evaluated to boolean by function boolean()
, and there is a rule:
Filters are always evaluated with respect to a context.
When you need to compare text()
or .
with a string "Data"
, it first uses string()
function to transform those to string type, than gets a boolean result.
There are two important rule about string()
:
The string()
function converts a node-set to a string by returning the string value of the first node in the node-set, which in some instances may yield unexpected results.
text()
is relative path that return a node-set contains all the text node of current node(context node), like ["Data"]
.
When it is evaluated by string(["Data"])
, it will return the first node of node-set, so you get "Data" only when there is only one text node in the node-set.
If you want the string()
function to concatenate all child text, you must then pass a single node instead of a node-set.
For example, we get a node-set ['a', 'b']
, you can pass there parent node to string(parent)
, this will return 'ab'
, and of cause string(.)
in you case will return an concatenated string "Data"
.
Both way will get same result only when there is a text node.
Eloquent has a method for that (Laravel 4.*/5.*);
Model::whereNotNull('sent_at')
Laravel 3:
Model::where_not_null('sent_at')
The problem is that you aren't correctly escaping the input string, try:
echo "\"member\":\"time\"" | grep -e "member\""
Alternatively, you can use unescaped double quotes within single quotes:
echo '"member":"time"' | grep -e 'member"'
It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd'
).
Follow these simple steps:
I had the same error message. In my case I had inadvertently mixed the ES6 export default function myFunc
syntax with const myFunc = require('./myFunc');
.
Using module.exports = myFunc;
instead solved the issue.
You can do:
du -h your_directory
which will give you the size of your target directory.
If you want a brief output, du -hcs your_directory
is nice.
I know this is old, but a combination of these ideas leads to a very elegant solution:
Keep all the default property settings for the DropDownList (AppendDataBoundItems=false, Items empty). Then handle the DataBound event like this:
protected void dropdown_DataBound(object sender, EventArgs e)
{
DropDownList list = sender as DropDownList;
if (list != null)
list.Items.Insert(0, "--Select One--");
}
The icing on the cake is that this one handler can be shared by any number of DropDownList objects, or even put into a general-purpose utility library for all your projects.
If anyone's having trouble with this (as I was), you can get the postback code for a button by adding the UseSubmitBehavior="false" attribute to it. If you examine the rendered source of the button, you'll see the exact javascript you need to execute. In my case it was using the name of the button rather than the id.
If you still get error after running,
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Then try to download and install command line tool from https://developer.apple.com/download/more/ for your particular Mac os and Xcode version.
Then try to run,
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
and then
brew install node

Note: when you execute the command curl -I http://your-domain.com have to use single quotes in the command like curl -I 'http://your-domain.com'
If you are copying into a new table, the quickest way is probably what you have in your question, unless your rows are very large.
If your rows are very large, you may want to use the bulk insert functions in SQL Server. I think you can call them from C#.
Or you can first download that data into a text file, then bulk-copy (bcp) it. This has the additional benefit of allowing you to ignore keys, indexes etc.
Also try the Import/Export utility that comes with the SQL Management Studio; not sure whether it will be as fast as a straight bulk-copy, but it should allow you to skip the intermediate step of writing out as a flat file, and just copy directly table-to-table, which might be a bit faster than your SELECT INTO
statement.

Old question, but there's an easier way.
sns.pointplot(x=x_col,y=y_col,data=df_1,color='blue')
sns.pointplot(x=x_col,y=y_col,data=df_2,color='green')
sns.pointplot(x=x_col,y=y_col,data=df_3,color='red')
plt.legend(labels=['legendEntry1', 'legendEntry2', 'legendEntry3'])
This lets you add the plots sequentially, and not have to worry about any of the matplotlib crap besides defining the legend items.

Was the fix for me in MVC 4.
I would create a jUnit inner class that inherits from the abstract class. This can be instantiated and have access to all the methods defined in the abstract class.
public class AbstractClassTest {
public void testMethod() {
...
}
}
class ConcreteClass extends AbstractClass {
}
Not quite perfect, but it got me closer than some of the top answers here.
Two different tables, one with the header, and the other, wrapped with a div with the content

You can use one of these methods to convert number to an ASCII / Unicode / UTF-16 character:
You can use these methods convert the value of the specified 32-bit signed integer to its Unicode character:
char c = (char)65;
char c = Convert.ToChar(65);
Also, ASCII.GetString
decodes a range of bytes from a byte array into a string:
string s = Encoding.ASCII.GetString(new byte[]{ 65 });
Keep in mind that, ASCIIEncoding
does not provide error detection. Any byte greater than hexadecimal 0x7F is decoded as the Unicode question mark ("?").
Add below dependency in pom.xml:

Was facing the same issue as the return type cannot be bind with the MediaType of Class Foo. After adding the dependency it worked.
Actually, upon further reading on the file_get_contents()
function:
// Create a stream
$opts = [
"http" => [
"method" => "GET",
"header" => "Accept-language: en\r\n" .
"Cookie: foo=bar\r\n"
]
];
// DOCS: https://www.php.net/manual/en/function.stream-context-create.php
$context = stream_context_create($opts);
// Open the file using the HTTP headers set above
// DOCS: https://www.php.net/manual/en/function.file-get-contents.php
$file = file_get_contents('http://www.example.com/', false, $context);
You may be able to follow this pattern to achieve what you are seeking to, I haven't personally tested this though. (and if it doesn't work, feel free to check out my other answer)
You will have to use the fluent API to do this.
Try adding the following to your DbContext
:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<User>()
.HasOptional(a => a.UserDetail)
.WithOptionalDependent()
.WillCascadeOnDelete(true);
}
An interface defines a simple contract of methods all implementing classes must implement. When a class implements an interface, it must provide implementations for all its methods.
I guess the poster assumes a certain level of knowledge about the language.
Try this:
user._id.toString()
A MongoDB ObjectId is a 12-byte UUID can be used as a HEX string representation with 24 chars in length. You need to convert it to string to show it in console
using console.log
.
So, you have to do this:
console.log(user._id.toString());
One can easily use
CONVERT_TZ(your_timestamp_column_name, 'UTC', 'your_desired_timezone_name')
For example:
CONVERT_TZ(timeperiod, 'UTC', 'Asia/Karachi')
Plus this can also be used in WHERE statement and to compare timestamp i would use the following in Where clause:
WHERE CONVERT_TZ(timeperiod, 'UTC', '{$this->timezone}') NOT BETWEEN {$timeperiods['today_start']} AND {$timeperiods['today_end']}
To add a row:
DataRow row = dt.NewRow();
row["Name"] = "Ravi";
row["Marks"] = 500;
dt.Rows.Add(row);
To see the structure:
Table.Columns
I had this issue occurring with mailto:
and tel:
links inside an iframe (in Chrome, not a webview). Clicking the links would show the grey "page not found" page and inspecting the page showed it had a ERR_UNKNOWN_URL_SCHEME error.
Adding target="_blank"
, as suggested by this discussion of the issue fixed the problem for me.
You've got basically 2 options for "global" variables:
$rootScope
http://docs.angularjs.org/api/ng.$rootScope$rootScope
is a parent of all scopes so values exposed there will be visible in all templates and controllers. Using the $rootScope
is very easy as you can simply inject it into any controller and change values in this scope. It might be convenient but has all the problems of global variables.
Services are singletons that you can inject to any controller and expose their values in a controller's scope. Services, being singletons are still 'global' but you've got far better control over where those are used and exposed.
Using services is a bit more complex, but not that much, here is an example:
var myApp = angular.module('myApp',[]);
myApp.factory('UserService', function() {
return {
name : 'anonymous'
};
});
and then in a controller:
function MyCtrl($scope, UserService) {
$scope.name = UserService.name;
}
Here is the working jsFiddle: http://jsfiddle.net/pkozlowski_opensource/BRWPM/2/
Although this has been answer https://stackoverflow.com/a/28375912/5413283, and regarding padding it is not mentioned in the original answer but here https://stackoverflow.com/a/33697157/5413283.
i am just adding here for visual presentation and a cleaner code.
Create a new parent div and add the bootstrap collapse. Remove the classes from the textarea
<div class="collapse" id="collapseOne"> <!-- bootstrap class on parent -->
<textarea class="form-control" rows="4"></textarea>
</div> <!-- // bootstrap class on parent -->
If you want to have spaces around, wrap textarea
with padding. Do not add margin
, it has the same issue.
<div class="collapse" id="collapseOne"> <!-- bootstrap class on parent -->
<div class="py-4"> <!-- padding for textarea -->
<textarea class="form-control" rows="4"></textarea>
</div> <!-- // padding for textarea -->
</div> <!-- // bootstrap class on parent -->
Same as bootstrap 4. Wrap the textare
with collapse
class.
<div class="collapse" id="collapseOne"> <!-- bootstrap class on parent -->
<textarea class="form-control" rows="4"></textarea>
</div> <!-- // bootstrap class on parent -->
And for padding
Bootstrap 3 does not have p-* classes like Bootstrap 4 . So you need to create your own. Do not use padding
it will not work, use margin
.
#collapseOne textarea {
margin: 10px 0 10px 0;
}
it seems that the ubuntu community has completed the documentation on installing openCV,

From a quick search, Oracle appears to use double quotes ("

How about the Live method?

::
is the scope resolution operator. It's used to specify the scope of something.
For example, ::
alone is the global scope, outside all other namespaces.
some::thing
can be interpreted in any of the following ways:
some
is a namespace (in the global scope, or an outer scope than the current one) and thing
is a type, a function, an object or a nested namespace;some
is a class available in the current scope and thing
is a member object, function or type of the some
class;some
can be a base type of the current type (or the current type itself) and thing
is then one member of this class, a type, function or object.You can also have nested scope, as in some::thing::bad
. Here each name could be a type, an object or a namespace. In addition, the last one, bad
, could also be a function. The others could not, since functions can't expose anything within their internal scope.
So, back to your example, ::thing
can be only something in the global scope: a type, a function, an object or a namespace.
The way you use it suggests (used in a pointer declaration) that it's a type in the global scope.
I hope this answer is complete and correct enough to help you understand scope resolution.
You can look at the Django framework for how they create a "slug" from arbitrary text. A slug is URL- and filename- friendly.
The Django text utils define a function, slugify()
, that's probably the gold standard for this kind of thing. Essentially, their code is the following.
import unicodedata
import re
def slugify(value, allow_unicode=False):
"""
Taken from https://github.com/django/django/blob/master/django/utils/text.py
Convert to ASCII if 'allow_unicode' is False. Convert spaces or repeated
dashes to single dashes. Remove characters that aren't alphanumerics,
underscores, or hyphens. Convert to lowercase. Also strip leading and
trailing whitespace, dashes, and underscores.
"""
value = str(value)
if allow_unicode:
value = unicodedata.normalize('NFKC', value)
else:
value = unicodedata.normalize('NFKD', value).encode('ascii', 'ignore').decode('ascii')
value = re.sub(r'[^\w\s-]', '', value.lower())
return re.sub(r'[-\s]+', '-', value).strip('-_')
And the older version:
def slugify(value):
"""
Normalizes string, converts to lowercase, removes non-alpha characters,
and converts spaces to hyphens.
"""
import unicodedata
value = unicodedata.normalize('NFKD', value).encode('ascii', 'ignore')
value = unicode(re.sub('[^\w\s-]', '', value).strip().lower())
value = unicode(re.sub('[-\s]+', '-', value))
# ...
return value
There's more, but I left it out, since it doesn't address slugification, but escaping.
Since Spark 1.5 you can use a number of date processing functions:
pyspark.sql.functions.year
pyspark.sql.functions.month
pyspark.sql.functions.dayofmonth
pyspark.sql.functions.dayofweek()
pyspark.sql.functions.dayofyear
pyspark.sql.functions.weekofyear()
import datetime
from pyspark.sql.functions import year, month, dayofmonth
elevDF = sc.parallelize([
(datetime.datetime(1984, 1, 1, 0, 0), 1, 638.55),
(datetime.datetime(1984, 1, 1, 0, 0), 2, 638.55),
(datetime.datetime(1984, 1, 1, 0, 0), 3, 638.55),
(datetime.datetime(1984, 1, 1, 0, 0), 4, 638.55),
(datetime.datetime(1984, 1, 1, 0, 0), 5, 638.55)
]).toDF(["date", "hour", "value"])
elevDF.select(
year("date").alias('year'),
month("date").alias('month'),
dayofmonth("date").alias('day')
).show()
# +----+-----+---+
# |year|month|day|
# +----+-----+---+
# |1984| 1| 1|
# |1984| 1| 1|
# |1984| 1| 1|
# |1984| 1| 1|
# |1984| 1| 1|
# +----+-----+---+
You can use simple map
as with any other RDD:
elevDF = sqlContext.createDataFrame(sc.parallelize([
Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=1, value=638.55),
Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=2, value=638.55),
Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=3, value=638.55),
Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=4, value=638.55),
Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=5, value=638.55)]))
(elevDF
.map(lambda (date, hour, value): (date.year, date.month, date.day))
.collect())
and the result is:
[(1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1)]
Btw: datetime.datetime
stores an hour anyway so keeping it separately seems to be a waste of memory.
The following functions are available to obtain the current date and/or time in PostgreSQL:
CURRENT_TIME
CURRENT_DATE
CURRENT_TIMESTAMP
Example
SELECT CURRENT_TIME;
08:05:18.864750+05:30
SELECT CURRENT_DATE;
2020-05-14
SELECT CURRENT_TIMESTAMP;
2020-05-14 08:04:51.290498+05:30
Using OpenSSL's EVP interface (the following is for OpenSSL 1.1):

#include <sstream>
#include <string>
#include <openssl/evp.h>
bool computeHash(const std::string& unhashed, std::string& hashed)
{
bool success = false;
EVP_MD_CTX* context = EVP_MD_CTX_new();
if(context != NULL)
{
if(EVP_DigestInit_ex(context, EVP_sha256(), NULL))
{
if(EVP_DigestUpdate(context, unhashed.c_str(), unhashed.length()))
{
unsigned char hash[EVP_MAX_MD_SIZE];
unsigned int lengthOfHash = 0;
if(EVP_DigestFinal_ex(context, hash, &lengthOfHash))
{
std::stringstream ss;
for(unsigned int i = 0; i < lengthOfHash; ++i)
{
ss << std::hex << std::setw(2) << std::setfill('0') << (int)hash[i];
}
hashed = ss.str();
success = true;
}
}
}
EVP_MD_CTX_free(context);

return success;
}
int main(int, char**)
{
std::string pw1 = "password1", pw1hashed;
std::string pw2 = "password2", pw2hashed;
std::string pw3 = "password3", pw3hashed;
std::string pw4 = "password4", pw4hashed;
hashPassword(pw1, pw1hashed);
hashPassword(pw2, pw2hashed);
hashPassword(pw3, pw3hashed);
hashPassword(pw4, pw4hashed);
std::cout << pw1hashed << std::endl;
std::cout << pw2hashed << std::endl;
std::cout << pw3hashed << std::endl;
std::cout << pw4hashed << std::endl;
return 0;
}
The advantage of this higher level interface is that you simply need to swap out the EVP_sha256()
call with another digest's function, e.g. EVP_sha512()
, to use a different digest. So it adds some flexibility.

in case you are interested in reading some data from a .txt
