I'd like to add to bosnic's answer that any valid currency character is legal for an identifier in Java. th€is is a legal identifier, as is €this, and € as well. However, I can't figure out how to edit his or her answer, so I am forced to post this trivial addition.
Whether null char is allowed or not really depends on base64 codec in question. Given vagueness of Base64 standard (there is no authoritative exact specification), many implementations would just ignore it as white space. And then others can flag it as a problem. And buggiest ones wouldn't notice and would happily try decoding it... :-/
But it sounds c# implementation does not like it (which is one valid approach) so if removing it helps, that should be done.
One minor additional comment: UTF-8 is not a requirement, ISO-8859-x aka Latin-x, and 7-bit Ascii would work as well. This because Base64 was specifically designed to only use 7-bit subset which works with all 7-bit ascii compatible encodings.
Here is a detail for int.Parse
and Convert.ToInt32
:
Say, you have a char array, char[] a=['1','2','3','4']
and want to convert each element into an integer.
The Convert.ToInt32(a[0])
will give you a number of 49. It treats it as ASCII code
The int.Parse(a[0])
will give you the right output which is 1
If you have a string array string[] b=['1','2','3','4']
, then Convert.ToInt32
and int.Parse
will have no difference in output. Both return the right integer.
It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.
The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:
You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:
Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:
#toolbar=0&navpanes=0
So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.
string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);
You can read more about the parameters that are available for customizing the way PDF files open here on Adobe's developer website.
You can pass arbitrary parameters through the query string, but you can also set up custom routes to handle it in a RESTful way:
http://ws.audioscrobbler.com/2.0/?method=artist.getimages&artist=cher&
api_key=b25b959554ed76058ac220b7b2e0a026
That could be:
routes.MapRoute(
"ArtistsImages",
"{ws}/artists/{artist}/{action}/{*apikey}",
new { ws = "2.0", controller="artists" artist = "", action="", apikey="" }
);
So if someone used the following route:
ws.audioscrobbler.com/2.0/artists/cher/images/b25b959554ed76058ac220b7b2e0a026/
It would take them to the same place your example querystring did.
The above is just an example, and doesn't apply the business rules and constraints you'd have to set up to make sure people didn't 'hack' the URL.

Perhaps a contrived "real world" example would help.
At my place of work we have rubbish bins that come in different flavours. All bins contain rubbish, but some bins are specialist and do not take all types of rubbish. So we have Bin<CupRubbish>
and Bin<RecylcableRubbish>
. The type system needs to make sure I can't put my HalfEatenSandwichRubbish
into either of these types, but it can go into a general rubbish bin Bin<Rubbish>
. If I wanted to talk about a Bin
of Rubbish
which may be specialised so I can't put in incompatible rubbish, then that would be Bin<? extends Rubbish>
.
(Note: ? extends
does not mean read-only. For instance, I can with proper precautions take out a piece of rubbish from a bin of unknown speciality and later put it back in a different place.)
Not sure how much that helps. Pointer-to-pointer in presence of polymorphism isn't entirely obvious.
In a Android app I was building, I had three EditText
s in a LinearLayout
arranged horizontally. I had to prevent the soft keyboard from appearing when the fragment loaded. In addition to setting focusable
and focusableInTouchMode
to true on the LinearLayout
, I had to set descendantFocusability
to blocksDescendants
. In onCreate
, I called requestFocus
on the LinearLayout
. This prevented the keyboard from appearing when the fragment is created.
Layout -
<LinearLayout
android:id="@+id/text_selector_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="3"
android:orientation="horizontal"
android:focusable="true"
android:focusableInTouchMode="true"
android:descendantFocusability="blocksDescendants"
android:background="@color/black">
<!-- EditText widgets -->
</LinearLayout>
In onCreate
- mTextSelectorContainer.requestFocus();

for this you need to install, prefer anaconda and it only works for words, not sentences so that's a limitation u gonna face.
from autocorrect import spell
print(spell('intrerpreter'))
# output: interpreter
It's also useful to have a slightly different name for the output executable. You can't use something like:
release: Target = ProgramName
debug: Target = ProgramName_d
Why it doesn't work is not clear, but it does not. But:
CONFIG(debug, debug|release) {
TARGET = ProgramName
} else {
TARGET = ProgramName_d
}
This does work as long as the CONFIG +=
line precedes it.
Don't cast unless you must. There's nothign wrong with calling toString().
Note that the if $myVar; then ... ;fi
construct has a security problem you might want to avoid with
case $myvar in
(true) echo "is true";;
(false) echo "is false";;
(rm -rf*) echo "I just dodged a bullet";;
esac
You might also want to rethink why if [ "$myvar" = "true" ]
appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case
solution is also handled without forks.
I just found this excellent little tutorial. broken link (Cached version)
I also followed Microsoft's tutorial which is nice, but I only needed pipes as well.
As you can see, you don't need configuration files and all that messy stuff.
By the way, he uses both HTTP and pipes. Just remove all code lines related to HTTP, and you'll get a pure pipe example.
There are 10^6 values in a range of 10^8, so there's one value per hundred code points on average. Store the distance from the Nth point to the (N+1)th. Duplicate values have a skip of 0. This means that the skip needs an average of just under 7 bits to store, so a million of them will happily fit into our 8 million bits of storage.
These skips need to be encoded into a bitstream, say by Huffman encoding. Insertion is by iterating through the bitstream and rewriting after the new value. Output by iterating through and writing out the implied values. For practicality, it probably wants to be done as, say, 10^4 lists covering 10^4 code points (and an average of 100 values) each.
A good Huffman tree for random data can be built a priori by assuming a Poisson distribution (mean=variance=100) on the length of the skips, but real statistics can be kept on the input and used to generate an optimal tree to deal with pathological cases.
Here is a simple javascript only solution
function displayOverlay(text) {
$("<table id='overlay'><tbody><tr><td>" + text + "</td></tr></tbody></table>").css({
"position": "fixed",
"top": 0,
"left": 0,
"width": "100%",

}
function removeOverlay() {

I was given this as an interview question once, I suspect this has happened to you and you are coming here for help. Break the problem into three questions and it becomes easier.
Problem 1) Use the iterator pattern to provide a way of iterating route results. A good place to put the logic to get the next route is probably the "moveNext" of your iterator. To find a valid route, it depends on your data structure. For me it was a sql table full of valid route possibilities so I had to build a query to get the valid destinations given a source.
Problem 2) Push each node as you find them into a collection as you get them, this means that you can see if you are "doubling back" over a point very easily by interrogating the collection you are building on the fly.
Problem 3) If at any point you see you are doubling back, you can pop things off the collection and "back up". Then from that point try to "move forward" again.
Hack: if you are using Sql Server 2008 there is are some new "hierarchy" things you can use to quickly solve this if you structure your data in a tree.
Another example with Call, Apply and Bind. The difference between Call and Apply is evident, but Bind works like this:
}
function Person(name) {
this.name = name;
}
Person.prototype.getName = function(a,b) {
return this.name + " " + a + " " + b;
}
var reader = new Person('John Smith');
reader.getName = function() {
// Apply and Call executes the function and returns value
// Also notice the different ways of extracting 'getName' prototype
var baseName = Object.getPrototypeOf(this).getName.apply(this,["is a", "boy"]);
console.log("Apply: " + baseName);
var baseName = Object.getPrototypeOf(reader).getName.call(this, "is a", "boy");
console.log("Call: " + baseName);
// Bind returns function which can be invoked
var baseName = Person.prototype.getName.bind(this, "is a", "boy");
console.log("Bind: " + baseName());
}
reader.getName();
/* Output
Apply: John Smith is a boy
Call: John Smith is a boy
Bind: John Smith is a boy
*/
You have a couple of questions here, so I'll address them separately:
My general rule is: don't. This is something which all but requires a second table (or third) with a foreign key. Sure, it may seem easier now, but what if the use case comes along where you need to actually query for those items individually? It also means that you have more options for lazy instantiation and you have a more consistent experience across multiple frameworks/languages. Further, you are less likely to have connection timeout issues (30,000 characters is a lot).
You mentioned that you were thinking about using ENUM. Are these values fixed? Do you know them ahead of time? If so this would be my structure:
Base table (what you have now):
| id primary_key sequence
| -- other columns here.
Items table:
| id primary_key sequence
| descript VARCHAR(30) UNIQUE
Map table:
| base_id bigint
| items_id bigint
Map table would have foreign keys so base_id maps to Base table, and items_id would map to the items table.
And if you'd like an easy way to retrieve this from a DB, then create a view which does the joins. You can even create insert and update rules so that you're practically only dealing with one table.
If you have to do something like this, why not just use a character delineated string? It will take less processing power than a CSV, XML, or JSON, and it will be shorter.
Personally, I would use TEXT
. It does not sound like you'd gain much by making this a BLOB
, and TEXT
, in my experience, is easier to read if you're using some form of IDE.
You can kill Jenkins safely. It will catch SIGTERM and SIGINT and perform an orderly shutdown. However, if Jenkins was in the middle of building something, it will abort the builds and they will show up gray in the status display.
If you want to avoid this, you must put Jenkins into shutdown mode to prevent it from starting new builds and wait until currently running builds are done before killing Jenkins.
You can also use the Jenkins command line interface and tell Jenkins to safe-shutdown, which does the same. You can find more info on Jenkins cli at http://YOURJENKINS/cli

on the WindowI've got a similar error when installing FCL that needs CCD lib(libccd) like this:
/usr/bin/ld: /usr/local/lib/libccd.a(ccd.o): relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; recompile with -fPIC
I find that there is two different files named "libccd.a" :
I solved the problem by removing the first file.
Many time this error is caused when you update a product in your custom module's observer as shown below.
class [NAMESPACE]_[MODULE NAME]_Model_Observer
{
/**
* Flag to stop observer executing more than once
*
* @var static bool
*/
static protected $_singletonFlag = false;
public function saveProductData(Varien_Event_Observer $observer)
{
if (!self::$_singletonFlag) {
self::$_singletonFlag = true;
$product = $observer->getEvent()->getProduct();
//do stuff to the $product object
// $product->save(); // commenting out this line prevents the error
$product->getResource()->save($product);
}
}
Hence whenever you save your product after updating some properties in your module's observer use $product->getResource()->save($product)
instead of $product->save()
You can use >>
to print in another file.
echo "hello" >> logfile.txt
In this specific case, the ToString() will return the name of the object retruned by the SelectedCell Property.( a collection of the currently selected cells).
This behavior occurs when an object has no specific implenetation for the ToString() methods.
in our case, all you have to do is to iterate the collection of the cells and to accumulate its values to a string. then push this string to the TextBox.
have a look here how to implement the iteration:
You can run MSSQL and .NET Core on Linux, and hence inside Linux containers, nowadays.
See: https://hub.docker.com/r/microsoft/mssql-server-linux/
Also: https://hub.docker.com/r/microsoft/dotnet/
The direct question to your answer, is of course, unless there is a version compiled especially for Linux, no.
Take a look at the Cursor.Position
Property. It should get you started.
private void MoveCursor()
{
// Set the Current cursor, move the cursor's Position,
// and set its clipping rectangle to the form.
this.Cursor = new Cursor(Cursor.Current.Handle);
Cursor.Position = new Point(Cursor.Position.X - 50, Cursor.Position.Y - 50);
Cursor.Clip = new Rectangle(this.Location, this.Size);
}
Those arrows are part of the Shadow DOM, which are basically DOM elements on your page which are hidden from you. If you're new to the idea, a good introductory read can be found here.
For the most part, the Shadow DOM saves us time and is good. But there are instances, like this question, where you want to modify it.
You can modify these in Webkit now with the right selectors, but this is still in the early stages of development. The Shadow DOM itself has no unified selectors yet, so the webkit selectors are proprietary (and it isn't just a matter of appending -webkit
, like in other cases).
Because of this, it seems likely that Opera just hasn't gotten around to adding this yet. Finding resources about Opera Shadow DOM modifications is tough, though. A few unreliable internet sources I've found all say or suggest that Opera doesn't currently support Shadow DOM manipulation.
I spent a bit of time looking through the Opera website to see if there'd be any mention of it, along with trying to find them in Dragonfly...neither search had any luck. Because of the silence on this issue, and the developing nature of the Shadow DOM + Shadow DOM manipulation, it seems to be a safe conclusion that you just can't do it in Opera, at least for now.
I'm answering this question as it's a highly viewed, and there are many answers out there plus there's Swift and Obj-C.

Welcome to hell.
You can just pass a datetime64 object to pandas.Timestamp
:
In [16]: Timestamp(numpy.datetime64('2012-05-01T01:00:00.000000'))
Out[16]: <Timestamp: 2012-05-01 01:00:00>
I noticed that this doesn't work right though in NumPy 1.6.1:
numpy.datetime64('2012-05-01T01:00:00.000000+0100')
Also, pandas.to_datetime
can be used (this is off of the dev version, haven't checked v0.9.1):
In [24]: pandas.to_datetime('2012-05-01T01:00:00.000000+0100')
Out[24]: datetime.datetime(2012, 5, 1, 1, 0, tzinfo=tzoffset(None, 3600))
std::string::data
would seem to be sufficient and most efficient. If you want to have non-const memory to manipulate (strange for encryption) you can copy the data to a buffer using memcpy:
unsigned char buffer[mystring.length()];
memcpy(buffer, mystring.data(), mystring.length());
STL fanboys would encourage you to use std::copy instead:
std::copy(mystring.begin(), mystring.end(), buffer);
but there really isn't much of an upside to this. If you need null termination use std::string::c_str()
and the various string duplication techniques others have provided, but I'd generally avoid that and just query for the length
. Particularly with cryptography you just know somebody is going to try to break it by shoving nulls in to it, and using std::string::data()
discourages you from lazily making assumptions about the underlying bits in the string.
I open a text editor, in my case I used Atom. Paste this code
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');
and save as
helloworld.js
in
c:\xampp\htdocs\myproject
directory. Next I open node.js commamd prompt enter
cd c:\xampp\htdocs\myproject
next
node helloworld.js
next I open my chrome browser and I type
http://localhost:1337
and there it is.
str.replace()
does fixed replacements. Use re.sub()
instead.
I suggest Oj as it is waaaaaay faster than the standard JSON library.

I FINALLY GOT THIS WORKING AFTER 2 SOUL DESTROYING EVENINGS OF TRYING! IF I EVER MEET AN ANDROID SDK DEVELOPER I WILL HACK HIM TO DEATH WITH HIS OWN KEYBOARD
Anyway, tips for getting it working on Windows 7 64 bit...
I suspect for me it was multiple problems as none of the suggestions worked so I will list all the things I did to finally get it working
1) Install the 32 BIT version of Java JDK (yes, even if you are running 64bit Windows)
2) Install both the SDK and the JDK to paths that have no spaces in (I used C:\Android and C:\Java32)
3) In the Windows environment variables screen (System Properties > Advanced Settings > Env vars), there's two places you can enter the variables, the "User Variables" and "System variables". I put them in both and included the "bin" bit in both e.g.
JAVA_HOME = C:\Java32\jdk1.8.0_20\bin
Path = C:\Java32\jdk1.8.0_20\bin;other paths should come AFTER the jdk...
4) Edit the file tools\android.bat and look for the following:
set java_exe=
call lib\find_java.bat
change this to:
set java_exe="C:\Java32\jdk1.8.0_20\bin\java.exe"
rem call lib\find_java.bat
You can also put the "@echo off" to "@echo on" at the top of the file for debugging purposes
Good luck!
When your button is disabled it directly sets the opacity. So first of all we have to set its opacity as
.v-button{
opacity:1;
}
I had the same program, I hope this could help.
I your using Windows 7, open Command Prompt-> run as Administrator. register your <...>.dll.
Why run as Administrator, you can register your <...>.dll using the run at the Windows Start, but still your dll only run as user even your account is administrator.
Now you can add your <...>.dll at the Project->Add Reference->Browse
Thanks
In VS 2015, removing 'Analyzers' under 'References' solved the issue
Have the certificate and bundle copied in one .crt file and make sure that there is a blank line between the certificates in the file.
This worked for me on a GitLab server after trying everything on the Internet.
Assume that you have MyPayments class like
public class Mypayment
{
public int year { get; set; }
public string month { get; set; }
public string price { get; set; }
public bool ispaid { get; set; }
}
and you have a list of MyPayments
public List<Mypayment> mypayments { get; set; }
and you want group the list by year. You can use linq like this:
List<List<Mypayment>> mypayments = (from IGrouping<int, Mypayment> item in yearGroup
let mypayments1 = (from _payment in UserProjects.mypayments
where _payment.year == item.Key
select _payment).ToList()
select mypayments1).ToList();
I always avoid changing prototype method and adding library so this is my solution:
Using reduce Array prototype method is sufficient
// + operator for casting to Number
items.reduce((a, b) => +a + +b.price, 0);
The other answers provided here mention using @selector(localizedCaseInsensitiveCompare:)
This works great for an array of NSString, however if you want to extend this to another type of object, and sort those objects according to a 'name' property, you should do this instead:
NSSortDescriptor *sort = [NSSortDescriptor sortDescriptorWithKey:@"name" ascending:YES];
sortedArray=[anArray sortedArrayUsingDescriptors:@[sort]];
Your objects will be sorted according to the name property of those objects.
If you want the sorting to be case insensitive, you would need to set the descriptor like this
NSSortDescriptor *sort = [NSSortDescriptor sortDescriptorWithKey:@"name" ascending:YES selector:@selector(caseInsensitiveCompare:)];
In my case, the original repository was a bare one.
So, I had to type (in windows):
mkdir dest
cd dest
git init
git remote add origin a\valid\yet\bare\repository
git pull origin master
To check if a repository is a bare one:
git rev-parse --is-bare-repository
In our case, deletion was not possible due to already having an app that we were in pre-release. The fix was not to delete but rather to edit each section, including version number, that needed to change for the new candidate.
To answer the question literally. It is not always true that x == x
double zero = 0.0;
double a[] = { 0,0,0,0,0, zero/zero}; // NaN
cout << (a[5] == 5[a] ? "true" : "false") << endl;
prints
false
If using NuGet all I had to do was:
right click project and click Manage NuGet Packages..
click the cog in top right
click General tab in NuGet Package Manager above Package Sources
check "Skip Applying binding redirects" in Binding Redirects
Clean and rebuild and the warning's gone
Easy peasy
Another way of Deleting a Column in Pandas DataFrame
if you're not looking for In-Place deletion then you can create a new DataFrame by specifying the columns using DataFrame(...)
function as
my_dict = { 'name' : ['a','b','c','d'], 'age' : [10,20,25,22], 'designation' : ['CEO', 'VP', 'MD', 'CEO']}
df = pd.DataFrame(my_dict)
Create a new DataFrame as
newdf = pd.DataFrame(df, columns=['name', 'age'])
You get a result as good as what you get with del / drop
There are different methods to open or close winform. Form.Close() is one method in closing a winform.
When 'Form.Close()' execute , all resources created in that form are destroyed. Resources means control and all its child controls (labels , buttons) , forms etc.
Some other methods to close winform
Some methods to Open/Start a form
All of them act differently , Explore them !
May be you initialize pDialog globally, Then remove it and intialize your view or dialog locally.I have same issue, I have done this and my issue is resolved. Hope it will work for u.
Update August 2019
In Android Studio 3.5 Instant Run was replaced with Apply Changes. And it works in different way: APK is not modified on the fly anymore but instead runtime instrumentation is used to redefine classes on the fly (more info). So since Android Studio 3.5 instant run settings are replaced with Deployment (Settings -> Build, Execution, Deployment -> Deployment):
What about "Apache Commons Lang 3" Pair
class and the relative subclasses ?
import org.apache.commons.lang3.tuple.ImmutablePair;
import org.apache.commons.lang3.tuple.Pair;
...
@SuppressWarnings("unchecked")
Pair<String, Integer>[] arr = new ImmutablePair[]{
ImmutablePair.of("A", 1),
ImmutablePair.of("B", 2)};
// both access the 'left' part
String key = arr[0].getKey();
String left = arr[0].getLeft();
// both access the 'right' part
Integer value = arr[0].getValue();
Integer right = arr[0].getRight();
ImmutablePair
is a specific subclass that does not allow the values in the pair to be modified, but there are others implementations with different semantic. These are the Maven coordinates, if you need them.

Just in case if someone needs this for Xamarin in c#:
Intent intent = new Intent(Intent.ActionInsert);
intent.SetData(Android.Provider.CalendarContract.Events.ContentUri);

Simplest of all solutions:
filtered_df = df[df['var2'].isnull()]
This filters and gives you rows which has only NaN
values in 'var2'
column.
I got the same issue. My solution was a foreach of radio buttons, with the image at the right of it. Since you can only choose a single option at radio, it works (like) a select.
Worket well for me. Hope it can help someone else.
You could designate a class for each cell in the second column.
<table>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
</table>
The following will return true if the element is an input:
$("#elementId").is("input")
or you can use the following to get the name of the tag:
$("#elementId").get(0).tagName

This has happened to me. My issue was caused when I didn't mount Docker file system correctly, so I configured the Disk Image Location and re-bind File sharing mount, and this now worked correctly. For reference, I use Docker Desktop in Windows.
Use eval
in a clean namespace:
>>> ns = {'__builtins__': None}
>>> eval('2 ** 4', ns)
16
The clean namespace should prevent injection. For instance:
>>> eval('__builtins__.__import__("os").system("echo got through")', ns)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 1, in <module>
AttributeError: 'NoneType' object has no attribute '__import__'
Otherwise you would get:
>>> eval('__builtins__.__import__("os").system("echo got through")')
got through
0
You might want to give access to the math module:
>>> import math
>>> ns = vars(math).copy()
>>> ns['__builtins__'] = None
>>> eval('cos(pi/3)', ns)
0.50000000000000011

For getting quick profile stats on an IPython notebook. One can embed line_profiler and memory_profiler straight into their notebooks.
Another useful package is Pympler. It is a powerful profiling package that's capable to track classes,objects,functions,memory leaks etc. Examples below, Docs attached.
!pip install line_profiler
!pip install memory_profiler
!pip install pympler
%load_ext line_profiler
%load_ext memory_profiler
%time print('Outputs CPU time,Wall Clock time')
#CPU times: user 2 µs, sys: 0 ns, total: 2 µs Wall time: 5.96 µs
Gives:
%timeit -r 7 -n 1000 print('Outputs execution time of the snippet')
#1000 loops, best of 7: 7.46 ns per loop
%prun -s cumulative 'Code to profile'
Gives:
%memit 'Code to profile'
#peak memory: 199.45 MiB, increment: 0.00 MiB
Gives:
#Example function
def fun():
for i in range(10):
print(i)
#Usage: %lprun <name_of_the_function> function
%lprun -f fun fun()
Gives:
sys.getsizeof('code to profile')
# 64 bytes
Returns the size of an object in bytes.
from pympler import asizeof
obj = [1,2,("hey","ha"),3]
print(asizeof.asizeof(obj,stats=4))
pympler.asizeof can be used to investigate how much memory certain Python objects consume. In contrast to sys.getsizeof, asizeof sizes objects recursively
from pympler import tracker
tr = tracker.SummaryTracker()
def fun():
li = [1,2,3]
di = {"ha":"haha","duh":"Umm"}
fun()
tr.print_diff()
Tracks the lifetime of a function.
Pympler package consists of a huge number of high utility functions to profile code. All of which cannot be covered here. See the documentation attached for verbose profile implementations.
Here is another option to see if a cell exists inside a range. In case you have issues with the Intersect solution as I did.
If InStr(range("NamedRange").Address, range("IndividualCell").Address) > 0 Then
'The individual cell exists in the named range
Else
'The individual cell does not exist in the named range
End If
InStr is a VBA function that checks if a string exists within another string.

You may need to declare the radio buttons in the onCreate method of your code and use them.
RadioButton rb1 = (RadioButton) findViewById(R.id.option1);
rb1.setChecked(true);
My solution was not to rely on the class name. object.constructor.name works in theory. But if you're using TypeScript in something like Ionic, as soon as you go to production it's going to go up in flames because Ionic's production mode minifies the Javascript code. So the classes get named things like "a" and "e."
What I ended up doing was having a typeName class in all my objects that the constructor assigns the class name to. So:
export class Person {
id: number;
name: string;
typeName: string;
constructor() {
typeName = "Person";
}
Yes that wasn't what was asked, really. But using the constructor.name on something that might potentially get minified down the road is just begging for a headache.

The current PyGame release, 1.9.6 doesn't support Python 3.9. I fyou don't want to wait for PyGame 2.0, you have to use Python 3.8. Alternatively, you can install a developer version by explicitly specifying the version (2.0.0.dev20 is the latest release at the time of writing):
pip install pygame==2.0.0.dev20
or try to install a pre-release version by enabling the --pre
option:
pip install pygame --pre
Use q
flag for quiet mode, and tell wget
to output to stdout with O-
(uppercase o) and redirect to /dev/null
to discard the output:
wget -qO- $url &> /dev/null
>
redirects application output (to a file). if >
is preceded by ampersand, shell redirects all outputs (error and normal) to the file right of >
. If you don't specify ampersand, then only normal output is redirected.
./app &> file # redirect error and standard output to file
./app > file # redirect standard output to file
./app 2> file # redirect error output to file
if file is /dev/null
then all is discarded.
This works as well, and simpler:
wget -O/dev/null -q $url
[HttpGet]
public RedirectResult Get()
{
return RedirectPermanent("https://www.google.com");
}

Alternative and much easier way is to use shapes instead of 9-patches. It is already explained here: https://stackoverflow.com/a/24725831/512011
Actually adding any header field to the NSURLRequest argument in shouldStartLoadWithRequest seems to work, because the request responds to setValue:ForHTTPHeaderField - but it doesn't actually work - the request is sent out without the header.
So I used this workaround in shouldStartLoadWithRequest which just copies the given request to a new mutable request, and re-loads it. This does in fact modify the header which is sent out.
if ( [request valueForHTTPHeaderField:@"MyUserAgent"] == nil )
{
NSMutableURLRequest *modRequest = [request mutableCopyWithZone:NULL];
[modRequest setValue:@"myagent" forHTTPHeaderField:@"MyUserAgent"];
[webViewArgument loadRequest:modRequest];
return NO;
}
Unfortunately, this still doesn't allow overriding the user-agent http header, which is apparently overwritten by Apple. I guess for overriding it you would have to manage a NSURLConnection by yourself.
I would take a different tack entirely. Don't RETURN in the middle of the method/function. Instead, just put the return value in a local variable and send it at the end.
Personally, I find the following to be more readable:
String result = "";
switch (something) {
case 0:
result = "blah";
break;
case 1:
result = "foo";
break;
}
return result;
You can also do as follows:
public static int[][] copy(int[][] src) {
int[][] dst = new int[src.length][];
for (int i = 0; i < src.length; i++) {
dst[i] = Arrays.copyOf(src[i], src[i].length);
}
return dst;
}
Try using delegate instead of live as here:
$('#link-wrapper').delegate('a', 'click', function() {
// do something ..
}
Effective final topic is described in JLS 4.12.4 and the last paragraph consists a clear explanation:
If a variable is effectively final, adding the final modifier to its declaration will not introduce any compile-time errors. Conversely, a local variable or parameter that is declared final in a valid program becomes effectively final if the final modifier is removed.
With Swift 5, according to your needs, you may choose one of the four following Playground code examples in order to solve your problem.
ClosedRange
reversed()
methodClosedRange
has a method called reversed()
. reversed()
method has the following declaration:
func reversed() -> ReversedCollection<ClosedRange<Bound>>
Returns a view presenting the elements of the collection in reverse order.
Usage:
let reversedCollection = (0 ... 5).reversed()
for index in reversedCollection {
print(index)
}
/*
Prints:
5
4
3
2
1
0
*/
As an alternative, you can use Range
reversed()
method:
let reversedCollection = (0 ..< 6).reversed()
for index in reversedCollection {
print(index)
}
/*
Prints:
5
4
3
2
1
0
*/
sequence(first:next:)
functionSwift Standard Library provides a function called sequence(first:next:)
. sequence(first:next:)
has the following declaration:
func sequence<T>(first: T, next: @escaping (T) -> T?) -> UnfoldFirstSequence<T>
Returns a sequence formed from
first
and repeated lazy applications ofnext
.
Usage:
let unfoldSequence = sequence(first: 5, next: {
$0 > 0 ? $0 - 1 : nil
})
for index in unfoldSequence {
print(index)
}
/*
Prints:
5
4
3
2
1
0
*/
stride(from:through:by:)
functionSwift Standard Library provides a function called stride(from:through:by:)
. stride(from:through:by:)
has the following declaration:
func stride<T>(from start: T, through end: T, by stride: T.Stride) -> StrideThrough<T> where T : Strideable
Returns a sequence from a starting value toward, and possibly including, an end value, stepping by the specified amount.
Usage:
let sequence = stride(from: 5, through: 0, by: -1)
for index in sequence {
print(index)
}
/*
Prints:
5
4
3
2
1
0
*/
As an alternative, you can use stride(from:to:by:)
:
let sequence = stride(from: 5, to: -1, by: -1)
for index in sequence {
print(index)
}
/*
Prints:
5
4
3
2
1
0
*/
AnyIterator
init(_:)
initializerAnyIterator
has an initializer called init(_:)
. init(_:)
has the following declaration:
init(_ body: @escaping () -> AnyIterator<Element>.Element?)
Creates an iterator that wraps the given closure in its
next()
method.
Usage:
var index = 5
guard index >= 0 else { fatalError("index must be positive or equal to zero") }
let iterator = AnyIterator({ () -> Int? in
defer { index = index - 1 }
return index >= 0 ? index : nil
})
for index in iterator {
print(index)
}
/*
Prints:
5
4
3
2
1
0
*/
If needed, you can refactor the previous code by creating an extension method for Int
and wrapping your iterator in it:
extension Int {
func iterateDownTo(_ endIndex: Int) -> AnyIterator<Int> {
var index = self
guard index >= endIndex else { fatalError("self must be greater than or equal to endIndex") }
let iterator = AnyIterator { () -> Int? in
defer { index = index - 1 }
return index >= endIndex ? index : nil
}
return iterator
}
}
let iterator = 5.iterateDownTo(0)
for index in iterator {
print(index)
}
/*
Prints:
5
4
3
2
1
0
*/
By using the null-conditional operator (?.
) you can get the HTTP status code with a single line of code:
HttpStatusCode? status = (ex.Response as HttpWebResponse)?.StatusCode;
The variable status
will contain the HttpStatusCode
. When the there is a more general failure like a network error where no HTTP status code is ever sent then status
will be null. In that case you can inspect ex.Status
to get the WebExceptionStatus
.
If you just want a descriptive string to log in case of a failure you can use the null-coalescing operator (??
) to get the relevant error:
string status = (ex.Response as HttpWebResponse)?.StatusCode.ToString()
?? ex.Status.ToString();
If the exception is thrown as a result of a 404 HTTP status code the string will contain "NotFound". On the other hand, if the server is offline the string will contain "ConnectFailure" and so on.
(And for anybody that wants to know how to get the HTTP substatus code. That is not possible. It is a Microsoft IIS concept that is only logged on the server and never sent to the client.)
You can also do just like this:
Task.Run(() => this.FunctionAsync()).Wait();
Note: Be careful about thread blocking!
Just add a new form and add buttons and a label. Give the value to be shown and the text of the button, etc. in its constructor, and call it from anywhere you want in the project.
In project -> Add Component -> Windows Form and select a form
Add some label and buttons.
Initialize the value in constructor and call it from anywhere.
public class form1:System.Windows.Forms.Form
{
public form1()
{
}
public form1(string message,string buttonText1,string buttonText2)
{
lblMessage.Text = message;
button1.Text = buttonText1;
button2.Text = buttonText2;
}
}
// Write code for button1 and button2 's click event in order to call
// from any where in your current project.
// Calling
Form1 frm = new Form1("message to show", "buttontext1", "buttontext2");
frm.ShowDialog();
This will work in .NET 4.7.2 with Visual Studio 2017 (15.9.4):
You can find more methods and functions related to Python strings in section 5.6.1. String Methods of the documentation.
w.strip(',.').lower()
If you have the HTML
<form name="formname" .... id="form-first">
<iframe id="one" src="iframe2.html">
</iframe>
</form>
and JavaScript
function iframeRef( frameRef ) {
return frameRef.contentWindow
? frameRef.contentWindow.document
: frameRef.contentDocument
}
var inside = iframeRef( document.getElementById('one') )
inside
is now a reference to the document, so you can do getElementsByTagName('textarea')
and whatever you like, depending on what's inside the iframe src.

I know that the question was how to do it with Jquery, but you can achieve the same affect with simple css and just a little jquery...
For example, you have a div with 'box' class, add the following css
.box {
background-color: black;
-webkit-transition: background 0.5s linear;
-moz-transition: background 0.5s linear;
-ms-transition: background 0.5s linear;
-o-transition: background 0.5s linear;
transition: background 0.5s linear;
}
and then use AddClass function to add another class with different background color like 'box highlighted' or something like that with the following css:
.box.highlighted {
background-color: white;
}
I am a beginner and maybe there are some disadvantages of this method but maybe it'll be helpful for somebody
Here's a codepen: https://codepen.io/anon/pen/baaLYB
It is not necessary to use another library like newChart or use other people's pull requests to pull this off. All you have to do is define an options object and add the label wherever and however you want it in the tooltip.
var optionsPie = {
tooltipTemplate: "<%= label %> - <%= value %>"
}
If you want the tooltip to be always shown you can make some other edits to the options:
var optionsPie = {
tooltipEvents: [],
showTooltips: true,
onAnimationComplete: function() {
this.showTooltip(this.segments, true);
},
tooltipTemplate: "<%= label %> - <%= value %>"
}
In your data items, you have to add the desired label property and value and that's all.
data = [
{
value: 480000,
color:"#F7464A",
highlight: "#FF5A5E",
label: "Tobacco"
}
];
Now, all you have to do is pass the options object after the data to the new Pie like this: new Chart(ctx).Pie(data,optionsPie)
and you are done.
This probably works best for pies which are not very small in size.
If none of those answers are working for you, try this. Add a submit button before the one that actually submits the form and just do nothing with the event.
HTML
<!-- The following button is meant to do nothing. This button will catch the "enter" key press and stop it's propagation. -->
<button type="submit" id="EnterKeyIntercepter" style="cursor: auto; outline: transparent;"></button>
JavaScript
$('#EnterKeyIntercepter').click((event) => {
event.preventDefault(); //The buck stops here.
/*If you don't know what this if statement does, just delete it.*/
if (process.env.NODE_ENV !== 'production') {
console.log("The enter key was pressed and captured by the mighty Enter Key Inceptor (¬¦_¦)");
}
});
This works for me: $('#profile1').attr('onclick')
InstallShield 12
INSTALLDIR
represents the main product installation directory for a regular Windows Installer–based (or InstallScript MSI) installation, such as the end user launching Setup.exe or your .msi database.
TARGETDIR
represents the installation directory for an InstallScript installation, or for an administrative Windows Installer based installation (when the user runs Setup.exe or MsiExec.exe with the /a command-line switch).In an InstallScript MSI project, the InstallScript variable
MSI_TARGETDIR
stores the target of an administrative installation.
Source: INSTALLDIR vs. TARGETDIR
If you need just one character and you don't want to keep things in the buffer, you can simply read a whole line and drop everything that isn't needed.
Replace:
stdin.read(1)
with
stdin.readline().strip()[:1]
This will read a line, remove spaces and newlines and just keep the first character.
I do believe you need to add the border: none style to your icon element as well.
I am creating a map view with itemized overlays. I was creating my itemizedoverlay like this from my mapActivity:
OCItemizedOverlay currentLocationOverlay = new OCItemizedOverlay(pin,getApplicationContext);
I found that I would get the "android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application" exception when my itemizedoverlay's onTap method was triggered(when the location is tapped on the mapview).
I found that if I simply passed, 'this' instead of 'getApplicationContext()' to my constructor, the problem went away. This seems to support alienjazzcat's conclusion. weird.
You can simply add show.legend=FALSE
to geom to suppress the corresponding legend

If you are using Kotlin make sure to take a look at what the Kotlin extensions by Google provide or just write your own.
I found a very good example here: https://bigcode.wordpress.com/2016/12/20/compiling-a-very-basic-mingw-windows-hello-world-executable-in-c-with-a-makefile/
It is a simple Hello.c (you can use c++ with g++ instead of gcc) using the MinGW on windows.
The Makefile looking like:
EXECUTABLE = src/Main.cpp
CC = "C:\MinGW\bin\g++.exe"
LDFLAGS = -lgdi32
src = $(wildcard *.cpp)
obj = $(src:.cpp=.o)
all: myprog
myprog: $(obj)
$(CC) -o $(EXECUTABLE) $^ $(LDFLAGS)
.PHONY: clean
clean:
del $(obj) $(EXECUTABLE)
The backslash (\
) is an escape character in Javascript (along with a lot of other C-like languages). This means that when Javascript encounters a backslash, it tries to escape the following character. For instance, \n
is a newline character (rather than a backslash followed by the letter n).
In order to output a literal backslash, you need to escape it. That means \\
will output a single backslash (and \\\\
will output two, and so on). The reason "aa ///\"
doesn't work is because the backslash escapes the "
(which will print a literal quote), and thus your string is not properly terminated. Similarly, "aa ///\\\"
won't work, because the last backslash again escapes the quote.
Just remember, for each backslash you want to output, you need to give Javascript two.
Remember that when you write:
MyArray = Range("A1:A5000")
you are really writing
MyArray = Range("A1:A5000").Value
You can also use names:
MyArray = Names("MyWSTable").RefersToRange.Value
But Value is not the only property of Range. I have used:
MyArray = Range("A1:A5000").NumberFormat
I doubt
MyArray = Range("A1:A5000").Font
would work but I would expect
MyArray = Range("A1:A5000").Font.Bold
to work.
I do not know what formats you want to copy so you will have to try.
However, I must add that when you copy and paste a large range, it is not as much slower than doing it via an array as we all thought.
Post Edit information
Having posted the above I tried by own advice. My experiments with copying Font.Color and Font.Bold to an array have failed.
Of the following statements, the second would fail with a type mismatch:
ValueArray = .Range("A1:T5000").Value
ColourArray = .Range("A1:T5000").Font.Color
ValueArray must be of type variant. I tried both variant and long for ColourArray without success.
I filled ColourArray with values and tried the following statement:
.Range("A1:T5000").Font.Color = ColourArray
The entire range would be coloured according to the first element of ColourArray and then Excel looped consuming about 45% of the processor time until I terminated it with the Task Manager.
There is a time penalty associated with switching between worksheets but recent questions about macro duration have caused everyone to review our belief that working via arrays was substantially quicker.
I constructed an experiment that broadly reflects your requirement. I filled worksheet Time1 with 5000 rows of 20 cells which were selectively formatted as: bold, italic, underline, subscript, bordered, red, green, blue, brown, yellow and gray-80%.
With version 1, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" using copy.
With version 2, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" by copying the value and the colour via an array.
With version 3, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" by copying the formula and the colour via an array.
Version 1 took an average of 12.43 seconds, version 2 took an average of 1.47 seconds while version 3 took an average of 1.83 seconds. Version 1 copied formulae and all formatting, version 2 copied values and colour while version 3 copied formulae and colour. With versions 1 and 2 you could add bold and italic, say, and still have some time in hand. However, I am not sure it would be worth the bother given that copying 21,300 values only takes 12 seconds.

You don't have to bind parameters if you use query builder or eloquent ORM. However, if you use DB::raw()
, ensure that you binding the parameters.
Try the following:
$array = array(1,2,3); $query = DB::table('offers'); $query->select('id', 'business_id', 'address_id', 'title', 'details', 'value', 'total_available', 'start_date', 'end_date', 'terms', 'type', 'coupon_code', 'is_barcode_available', 'is_exclusive', 'userinformations_id', 'is_used'); $query->leftJoin('user_offer_collection', function ($join) use ($array) { $join->on('user_offer_collection.offers_id', '=', 'offers.id') ->whereIn('user_offer_collection.user_id', $array); }); $query->get();

I struggled with the idea of centralizing a global error handling routine in an MVC app before. I have a post on the ASP.NET forums.
It basically handles all your application errors in the global.asax without the need for an error controller, decorating with the [HandlerError]
attribute, or fiddling with the customErrors
node in the web.config.
In my case solution is really silly, and strange.
Below code was pre-populated by _Layout.cshtml file. (NOT written by me)
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script src="~/Scripts/bootstrap.min.js"></script>
But, when I verified in Scripts folder, jquery-1.10.2.min.js was not even available. Hence, replaced code like below where jquery-1.9.1.min.js is an existing file:
<script src="~/Scripts/jquery-1.9.1.min.js"></script>
<script src="~/Scripts/bootstrap.min.js"></script>
If you haven't already, look at your php.ini
and make sure the parameters under the [mail function]

If you are using Spring Framework then there is a MediaType class for common content types:
MediaType.TEXT_HTML
MediaType.TEXT_PLAIN
MediaType.TEXT_XML
MediaType.APPLICATION_JSON
MediaType.IMAGE_JPEG

If you want your value to be read by MVT controller when you submit the form and you don't what to deal with hidden inputs. What you can do is add value
attribute to your checkbox
and set it to true
or false
.
MVT will not recognize viewModel property myCheckbox
as true here
<input type="checkbox" name="myCheckbox" checked="checked" />
but will if you add
<input type="checkbox" name="myCheckbox" checked="checked" value="true" />
Script that does it:
$(document).on("click", "[type='checkbox']", function(e) {
if (this.checked) {
$(this).attr("value", "true");
} else {
$(this).attr("value","false");}
});
Using this code for Navigating next viewcontroller,if you are using storyboard means follow this below code,
UIStoryboard *board;
if (!self.storyboard)
{
board = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
}
else
{
board = self.storyboard;
}
ViewController *View = [board instantiateViewControllerWithIdentifier:@"yourstoryboardname"];
[self.navigationController pushViewController:View animated:YES];
If you don't want to use the optgroup element, put the dashes in an option element instead and give it the disabled attribute. It will be visible, but greyed out.
<option disabled>----------</option>
If the number of files you want to view fits within the maximum argument limit you can use globbing to get what you want, with recursion if you have globstar support.
For exactly 2 layers deep use: ls -d * */*
With globstar, for recursion use: ls -d **/*
The -d
argument to ls
tells it not to recurse directories passed as arguments (since you are using the shell globbing to do the recursion). This prevents ls
using its recursion formatting.
Just to add to yamen's answer, which is perfect for images but not so much for text.
If you are trying to use this to scale text, like say a Word document (which is in this case in bytes from Word Interop), you will need to make a few modifications or you will get giant bars on the side.
May not be perfect but works for me!
using (MemoryStream ms = new MemoryStream(wordBytes))
{
float width = 3840;
float height = 2160;
var brush = new SolidBrush(Color.White);
var rawImage = Image.FromStream(ms);
float scale = Math.Min(width / rawImage.Width, height / rawImage.Height);
var scaleWidth = (int)(rawImage.Width * scale);
var scaleHeight = (int)(rawImage.Height * scale);
var scaledBitmap = new Bitmap(scaleWidth, scaleHeight);
Graphics graph = Graphics.FromImage(scaledBitmap);
graph.InterpolationMode = InterpolationMode.High;
graph.CompositingQuality = CompositingQuality.HighQuality;
graph.SmoothingMode = SmoothingMode.AntiAlias;
graph.FillRectangle(brush, new RectangleF(0, 0, width, height));
graph.DrawImage(rawImage, new Rectangle(0, 0 , scaleWidth, scaleHeight));
scaledBitmap.Save(fileName, ImageFormat.Png);
return scaledBitmap;
}
From, Programming Recommendations, PEP 8:
Comparisons to singletons like None should always be done with
is
oris not
, never the equality operators.Also, beware of writing
if x
when you really meanif x is not None
— e.g. when testing whether a variable or argument that defaults to None was set to some other value. The other value might have a type (such as a container) that could be false in a boolean context!
PEP 8 is essential reading for any Python programmer.
Python integers don't have an inherent length or number of significant digits. If you want them to print a specific way, you need to convert them to a string. There are several ways you can do so that let you specify things like padding characters and minimum lengths.
To pad with zeros to a minimum of three characters, try:
length = 1
print(format(length, '03'))
I would use ruby-build
with rbenv
. The following lines install Ruby 3.0.0 and set it as your default Ruby version:
$ brew update
$ brew install ruby-build
$ brew install rbenv
$ rbenv install 3.0.0
$ rbenv global 3.0.0
async function FileToString (file) {
try {
let res = await file.raw.text();
console.log(res);
} catch (err) {
throw err;
}
}
Or, written in one line:
std::cout << std::distance(sampleArray.begin(),std::max_element(sampleArray.begin(), sampleArray.end()));
If you fully trust the string and don't care about python injection attacks then this is very simple solution:
d = { 'method' : "eval", 'safe' : False, 'guarantees' : None }
s = str(d)
d2 = eval(s)
for k in d2:
print k+"="+d2[k]
If you're more safety conscious then ast.literal_eval
is a better bet.
I know its too late but this solution is working perfect for both .net framework and .net core:
@System.Web.HttpUtility.JavaScriptStringEncode()
Yet another method - create a filter function that returns True

EOF means end of file. It's a sign that the end of a file is reached, and that there will be no data anymore.
Edit:
I stand corrected. In this case it's not an end of file. As mentioned, it is passed when CTRL+d (linux) or CTRL+z (windows) is passed.
Apart from the client side validation with a Validator, I also recommend doing server side validation as well.

First of all, it's considered bad practice to extend Object.prototype
. Instead, provide your feature as utility function on Object
, just like there already are Object.keys
, Object.assign
, Object.is
, ...etc.
I provide here several solutions:
reduce
and Object.keys
Object.assign
map
and spread syntax instead of reduce
Object.entries
and Object.fromEntries
reduce
and Object.keys
With reduce
and Object.keys
to implement the desired filter (using ES6 arrow syntax):
Object.filter = (obj, predicate) => _x000D_
Object.keys(obj)_x000D_
.filter( key => predicate(obj[key]) )_x000D_
.reduce( (res, key) => (res[key] = obj[key], res), {} );_x000D_
_x000D_
// Example use:_x000D_
var scores = {_x000D_
John: 2, Sarah: 3, Janet: 1_x000D_
};_x000D_
var filtered = Object.filter(scores, score => score > 1); _x000D_
console.log(filtered);
_x000D_
Note that in the above code predicate
must be an inclusion condition (contrary to the exclusion condition the OP used), so that it is in line with how Array.prototype.filter
works.
Object.assign
In the above solution the comma operator is used in the reduce
part to return the mutated res
object. This could of course be written as two statements instead of one expression, but the latter is more concise. To do it without the comma operator, you could use Object.assign
instead, which does return the mutated object:
Object.filter = (obj, predicate) => _x000D_
Object.keys(obj)_x000D_
.filter( key => predicate(obj[key]) )_x000D_
.reduce( (res, key) => Object.assign(res, { [key]: obj[key] }), {} );_x000D_
_x000D_
// Example use:_x000D_
var scores = {_x000D_
John: 2, Sarah: 3, Janet: 1_x000D_
};_x000D_
var filtered = Object.filter(scores, score => score > 1); _x000D_
console.log(filtered);
_x000D_
map
and spread syntax instead of reduce
Here we move the Object.assign
call out of the loop, so it is only made once, and pass it the individual keys as separate arguments (using the spread syntax):
Object.filter = (obj, predicate) => _x000D_
Object.assign(...Object.keys(obj)_x000D_
.filter( key => predicate(obj[key]) )_x000D_
.map( key => ({ [key]: obj[key] }) ) );_x000D_
_x000D_
// Example use:_x000D_
var scores = {_x000D_
John: 2, Sarah: 3, Janet: 1_x000D_
};_x000D_
var filtered = Object.filter(scores, score => score > 1); _x000D_
console.log(filtered);
_x000D_
Object.entries
and Object.fromEntries
As the solution translates the object to an intermediate array and then converts that back to a plain object, it would be useful to make use of Object.entries
(ES2017) and the opposite (i.e. create an object from an array of key/value pairs) with Object.fromEntries
(ES2019).
It leads to this "one-liner" method on Object
:
Object.filter = (obj, predicate) => _x000D_
Object.fromEntries(Object.entries(obj).filter(predicate));_x000D_
_x000D_
// Example use:_x000D_
var scores = {_x000D_
John: 2, Sarah: 3, Janet: 1_x000D_
};_x000D_
_x000D_
var filtered = Object.filter(scores, ([name, score]) => score > 1); _x000D_
console.log(filtered);
_x000D_
The predicate function gets a key/value pair as argument here, which is a bit different, but allows for more possibilities in the predicate function's logic.
You start a thread which runs the static method SumData
. However, SumData
calls SetTextboxText
which isn't static. Thus you need an instance of your form to call SetTextboxText
.
If you are looking for a custom code instead of plugin, then this might help you. Facebook graph has under gone some changes since it has evolved. These steps are for the latest Graph API which I tried recently and worked well.
There are two main steps involved - 1. Getting Facebook Access Token, 2. Calling the Graph API passing the access token.
1. Getting the access token - Here is the step by step process to get the access token for your Facebook page. - Embed Facebook page feed on my website. As per this you need to create an app in Facebook developers page which would give you an App Id and an App Secret. Use these two and get the Access Token.
2. Calling the Graph API - This would be pretty simple once you get the access token. You just need to form a URL to Graph API with all the fields/properties you want to retrieve and make a GET request to this URL. Here is one example on how to do it in asp.net MVC. Embedding facebook feeds using asp.net mvc. This should be pretty similar in any other technology as it would be just a HTTP GET request.
Sample FQL Query: https://graph.facebook.com/FBPageName/posts?fields=full_picture,picture,link,message,created_time&limit=5&access_token=YOUR_ACCESS_TOKEN_HERE

The value returned by Date.prototype.toLocaleString is implementation dependent, so you get what you get. You can try to parse the string to remove seconds, but it may be different in different browsers so you'd need to make allowance for every browser in use.
Creating your own, unambiguous format isn't difficult using Date methods. For example:
function formatTimeHHMMA(d) {

Open httpd.conf of Apache server (backup first) Look for the the following : Listen
Change the line to
Listen *:80
Still in httpd.conf, look for the following (or similar):
<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Allow from all
Deny from all
</Directory>
Change this block to :
<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Allow from all
#Deny from all
</Directory>
Save httpd.conf and restart apache
Open port 80 of the server such that everyone can access your server.
Open Control Panel >> System and Security >> Windows Firewall then click on “Advance Setting” and then select “Inbound Rules” from the left panel and then click on “Add Rule…”. Select “PORT” as an option from the list and then in the next screen select “TCP” protocol and enter port number “80” under “Specific local port” then click on the ”Next” button and select “Allow the Connection” and then give the general name and description to this port and click Done.
Restart WAMP and access your machine in LAN or WAN.
In properly extending dimsuz's answer by providing a real code situation, see the following code snippet:
Drawable buttonDrawable = button.getBackground();
buttonDrawable = DrawableCompat.wrap(buttonDrawable);
//the color is a direct color int and not a color resource
DrawableCompat.setTint(buttonDrawable, Color.RED);
button.setBackground(buttonDrawable);
This solution is for the scenario where a drawable is used as the button's background. It works on pre-Lollipop devices as well.
One of the good things about handle.exe
is that you can run it as a subprocess and parse the output.
We do this in our deployment script - works like a charm.
Try This:
namespace SplashScreen
{
public partial class frmSplashScreen : Form
{
public frmSplashScreen()
{
InitializeComponent();
}
public int LeftTime { get; set; }
private void frmSplashScreen_Load(object sender, EventArgs e)
{
LeftTime = 20;
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
if (LeftTime > 0)
{
LeftTime--;
}
else
{
timer1.Stop();
new frmHomeScreen().Show();
this.Hide();
}
}
}
}
You should use java.time classes with Java 8 and later. To use java.time, add:
import java.time.* ;
Below is an example, how you can format date.
DateTimeFormatter format = DateTimeFormatter.ofPattern("dd-MMM-yyyy");
String date = "15-Oct-2018";
LocalDate localDate = LocalDate.parse(date, formatter);
System.out.println(localDate);
System.out.println(formatter.format(localDate));
LocalDate ld ....;
LocalDateTime ldtime ...;
ld.isEqual(LocalDate.from(ldtime));
Have you looked at the Maven Dependency Plugin ? That won't remove stuff for you but has tools to allow you to do the analysis yourself. I'm thinking particularly of
mvn dependency:tree
>>> dict(a=2,b=4)
{'a': 2, 'b': 4}
Will add the value in the python dictionary.
How about sys.exit()
from the module sys
.
If sys.exit()
is executed from within a thread it will close that thread only.
This answer here talks about that: Why does sys.exit() not exit when called inside a thread in Python?
Also, take a look at FrameLayout
, that's how the Camera's Gallery application implements the Zoom buttons overlay.
If you're using the Web Publish feature in IIS, then the solution I found was to edit the publish configuration and remove the Destination URL
from the configuration (leave it blank).
If this is defined, then every time you publish the project it will open the URL specified in the Destination URL
(which is a redirect URL).

esModuleInterop
generates the helpers outlined in the docs. Looking at the generated code, we can see exactly what these do:
//ts
import React from 'react'
//js
var __importDefault = (this && this.__importDefault) || function (mod) {
return (mod && mod.__esModule) ? mod : { "default": mod };
};
Object.defineProperty(exports, "__esModule", { value: true });
var react_1 = __importDefault(require("react"));
__importDefault
: If the module is not an es
module then what is returned by require becomes the default. This means that if you use default import on a commonjs
module, the whole module is actually the default.
__importStar
is best described in this PR:
TypeScript treats a namespace import (i.e.
import * as foo from "foo"
) as equivalent toconst foo = require("foo")
. Things are simple here, but they don't work out if the primary object being imported is a primitive or a value with call/construct signatures. ECMAScript basically says a namespace record is a plain object.Babel first requires in the module, and checks for a property named
__esModule
. If__esModule
is set totrue
, then the behavior is the same as that of TypeScript, but otherwise, it synthesizes a namespace record where:
- All properties are plucked off of the require'd module and made available as named imports.
- The originally require'd module is made available as a default import.
So we get this:
// ts
import * as React from 'react'
// emitted js
var __importStar = (this && this.__importStar) || function (mod) {
if (mod && mod.__esModule) return mod;
var result = {};
if (mod != null) for (var k in mod) if (Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
result["default"] = mod;
return result;
};
Object.defineProperty(exports, "__esModule", { value: true });
var React = __importStar(require("react"));
allowSyntheticDefaultImports
is the companion to all of this, setting this to false will not change the emitted helpers (both of them will still look the same). But it will raise a typescript error if you are using default import for a commonjs module. So this import React from 'react'
will raise the error Module '".../node_modules/@types/react/index"' has no default export.
if allowSyntheticDefaultImports
is false
.
There is a fundamental concept of IP routing: You must have a unique IP address if you want your machine to be reachable via the Internet. This is called a "Public IP Address". "www.whatismyipaddress.com" will give you this. If your server is behind some default gateway, IP packets would reach you via that router. You can not be reached via your private IP address from the outside world. You should note that private IP addresses of client and server may be same as long as their corresponding default gateways have different addresses (that's why IPv4 is still in effect) I guess you're trying to ping from your private address of your client to the public IP address of the server (provided by whatismyipaddress.com). This is not feasible. In order to achieve this, a mapping from private to public address is required, a process called Network Address Translation or NAT in short. This is configured in Firewall or Router. You can create your own private network (say via wifi). In this case, since your client and server would be on the same logical network, no private to public address translation would be required and hence you can communicate using your private IP addresses only.

yes in Virtuemart its must be button CLOSe-continue shopping, not element, because after click you can redirect.. i found this redirect bug on my ajax website.
Hm.
You have to specify window you clicked in Mouse.GetPosition(IInputElement relativeTo)
Following code works well for me
protected override void OnMouseDown(MouseButtonEventArgs e)
{
base.OnMouseDown(e);
Point p = e.GetPosition(this);
}
I suspect that you need to refer to the window not from it own class but from other point of the application. In this case Application.Current.MainWindow
will help you.
With PowerShell but without the need to create a script:
Invoke-WebRequest https://dist.nuget.org/win-x86-commandline/latest/nuget.exe -OutFile Nuget.exe
In PHP there is a global variable containing various details related to the server. It's called $_SERVER. It contains also the root:
$_SERVER['DOCUMENT_ROOT']
The only problem is that the entries in this variable are provided by the web server and there is no guarantee that all web servers offer them.
In Eclipse you can do it simply as follows :
Right click on your Java Project and select Export.
Select Java -> Runnable JAR file -> Next.
Select the Launch Configuration and choose project file as your Main class
Select the Destination folder where you would like to save it and click Finish.
I think if you study the theory of roman numerals carefully you don't require mappings for numbers 4,9,40 etc because the theory tells us if the roman numeral is IV = 5-1 = 4, hence when the prefix is smaller than the succeeding number in that case you have to subtract the former number from the succeeding number to get the actual value and this is what I have incorporated into my code for the problem, take a look and point out any mistakes if necessary, I followed this table to devise my logic - http://literacy.kent.edu/Minigrants/Cinci/romanchart.htm

If you need to add multiple key=>value, then try this.

If you support IE, for versions of Internet Explorer 8 and above, this:
<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7" />
Forces the browser to render as that particular version's standards. It is not supported for IE7 and below.
If you separate with semi-colon, it sets compatibility levels for different versions. For example:
<meta http-equiv="X-UA-Compatible" content="IE=7; IE=9" />
Renders IE7 and IE8 as IE7, but IE9 as IE9. It allows for different levels of backwards compatibility. In real life, though, you should only chose one of the options:
<meta http-equiv="X-UA-Compatible" content="IE=8" />
This allows for much easier testing and maintenance. Although generally the more useful version of this is using Emulate:
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />
For this:
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
It forces the browser the render at whatever the most recent version's standards are.
For more information, there is plenty to read about on MSDN,
Many algorithms will specify that duplicates are excluded. For example, the example algorithms in the MIT Algorithms book usually present examples without duplicates. It is fairly trivial to implement duplicates (either as a list at the node, or in one particular direction.)
Most (that I've seen) specify left children as <= and right children as >. Practically speaking, a BST which allows either of the right or left children to be equal to the root node, will require extra computational steps to finish a search where duplicate nodes are allowed.
It is best to utilize a list at the node to store duplicates, as inserting an '=' value to one side of a node requires rewriting the tree on that side to place the node as the child, or the node is placed as a grand-child, at some point below, which eliminates some of the search efficiency.
You have to remember, most of the classroom examples are simplified to portray and deliver the concept. They aren't worth squat in many real-world situations. But the statement, "every element has a key and no two elements have the same key", is not violated by the use of a list at the element node.
So go with what your data structures book said!
Edit:
Universal Definition of a Binary Search Tree involves storing and search for a key based on traversing a data structure in one of two directions. In the pragmatic sense, that means if the value is <>, you traverse the data structure in one of two 'directions'. So, in that sense, duplicate values don't make any sense at all.
This is different from BSP, or binary search partition, but not all that different. The algorithm to search has one of two directions for 'travel', or it is done (successfully or not.) So I apologize that my original answer didn't address the concept of a 'universal definition', as duplicates are really a distinct topic (something you deal with after a successful search, not as part of the binary search.)
Per numpy docs:
When operating on two arrays, NumPy compares their shapes element-wise. It starts with the trailing dimensions, and works its way forward. Two dimensions are compatible when:
- they are equal, or
- one of them is 1
In other words, if you are trying to multiply two matrices (in the linear algebra sense) then you want X.dot(y)
but if you are trying to broadcast scalars from matrix y
onto X
then you need to perform X * y.T
.
Example:
>>> import numpy as np
>>>
>>> X = np.arange(8).reshape(4, 2)
>>> y = np.arange(2).reshape(1, 2) # create a 1x2 matrix
>>> X * y
array([[0,1],
[0,3],
[0,5],
[0,7]])
You return four variables s1,s2,s3,s4 and receive them using a single variable obj
. This is what is called a tuple
, obj
is associated with 4 values, the values of s1,s2,s3,s4
. So, use index as you use in a list to get the value you want, in order.
obj=list_benefits()
print obj[0] + " is a benefit of functions!"
print obj[1] + " is a benefit of functions!"
print obj[2] + " is a benefit of functions!"
print obj[3] + " is a benefit of functions!"

You've not shown how you're creating the string 2016-01-12T23:00:00.000Z
, but I assume via .format()
.
Anyway, .set()
is using your local time zone, but the Z
in the time string indicates zero time, otherwise known as UTC.
https://en.wikipedia.org/wiki/ISO_8601#Time_zone_designators
So I assume your local timezone is 23 hours from UTC?
saikumar's answer showed how to load the time in as UTC, but the other option is to use a .format()
call that outputs using your local timezone, rather than UTC.

There is an 'exceptions' window in VS2005 ... try Ctrl+Alt+E when debugging and click on the 'Thrown' checkbox for the exception you want to stop on.
Correctness of Dijkstra's algorithm:
We have 2 sets of vertices at any step of the algorithm. Set A consists of the vertices to which we have computed the shortest paths. Set B consists of the remaining vertices.
Inductive Hypothesis: At each step we will assume that all previous iterations are correct.
Inductive Step: When we add a vertex V to the set A and set the distance to be dist[V], we must prove that this distance is optimal. If this is not optimal then there must be some other path to the vertex V that is of shorter length.
Suppose this some other path goes through some vertex X.
Now, since dist[V] <= dist[X] , therefore any other path to V will be atleast dist[V] length, unless the graph has negative edge lengths.
Thus for dijkstra's algorithm to work, the edge weights must be non negative.
There's a difference between additive colors (http://en.wikipedia.org/wiki/Additive_color) and subtractive colors (http://en.wikipedia.org/wiki/Subtractive_color).
With additive colors, the more you add, the brighter the colors become. This is because they are emitting light. This is why the day light is (more or less) white, since the Sun is emitting in almost all the visible wavelength spectrum.
On the other hand, with subtractive colors the more colors you mix, the darker the resulting color. This is because they are reflecting light. This is also why the black colors get hotter quickly, because it absorbs (almost) all light energy and reflects (almost) none.
Specifically to your question, it depends what medium you are working on. Traditionally, additive colors (RGB) are used because the canon for computer graphics was the computer monitor, and since it's emitting light, it makes sense to use the same structure for the graphic card (the colors are shown without conversions). However, if you are used to graphic arts and press, subtractive color model is used (CMYK). In programs such as Photoshop, you can choose to work in CMYK space although it doesn't matter what color model you use: the primary colors of one group are the secondary colors of the second one and viceversa.
P.D.: my father worked at graphic arts, this is why i know this... :-P
I've seen this anti-pattern from people who don't quite get the & address-of operator. If they need to call a function with a pointer, they'll always allocate on the heap so they get a pointer.

First we should know the order of execution of Clauses i.e FROM > WHERE > GROUP BY > HAVING > DISTINCT > SELECT > ORDER BY. Since WHERE Clause gets executed before GROUP BY Clause the records cannot be filtered by applying WHERE to a GROUP BY applied records.
"HAVING is same as the WHERE clause but is applied on grouped records".
first the WHERE clause fetches the records based on the condition then the GROUP BY clause groups them accordingly and then the HAVING clause fetches the group records based on the having condition.
Good article here: Cross-domain communication with iframes
Also you can directly set document.domain the same in both frames (even

code has sense because resets port to null), but this trick is not general-purpose.
Here is the answer for those of you looking like I did all over the web trying to find out how to do this task. Uploading a photo to a server with the file name stored in a mysql database and other form data you want in your Database. Please let me know if it helped.
Firstly the form you need:
<form method="post" action="addMember.php" enctype="multipart/form-data">
<p>
Please Enter the Band Members Name.
</p>
<p>
Band Member or Affiliates Name:
</p>
<input type="text" name="nameMember"/>
<p>
Please Enter the Band Members Position. Example:Drums.
</p>
<p>
Band Position:
</p>
<input type="text" name="bandMember"/>
<p>
Please Upload a Photo of the Member in gif or jpeg format. The file name should be named after the Members name. If the same file name is uploaded twice it will be overwritten! Maxium size of File is 35kb.
</p>
<p>
Photo:
</p>
<input type="hidden" name="size" value="350000">
<input type="file" name="photo">
<p>
Please Enter any other information about the band member here.
</p>
<p>
Other Member Information:
</p>
<textarea rows="10" cols="35" name="aboutMember">
</textarea>
<p>
Please Enter any other Bands the Member has been in.
</p>
<p>
Other Bands:
</p>
<input type="text" name="otherBands" size=30 />
<br/>
<br/>
<input TYPE="submit" name="upload" title="Add data to the Database" value="Add Member"/>
</form>
Then this code processes you data from the form:
<?php
// This is the directory where images will be saved
$target = "your directory";
$target = $target . basename( $_FILES['photo']['name']);
// This gets all the other information from the form
$name=$_POST['nameMember'];
$bandMember=$_POST['bandMember'];
$pic=($_FILES['photo']['name']);
$about=$_POST['aboutMember'];
$bands=$_POST['otherBands'];
// Connects to your Database
mysqli_connect("yourhost", "username", "password") or die(mysqli_error()) ;
mysqli_select_db("dbName") or die(mysqli_error()) ;
// Writes the information to the database
mysqli_query("INSERT INTO tableName (nameMember,bandMember,photo,aboutMember,otherBands)
VALUES ('$name', '$bandMember', '$pic', '$about', '$bands')") ;
// Writes the photo to the server
if(move_uploaded_file($_FILES['photo']['tmp_name'], $target))
{
// Tells you if its all ok
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory";
}
else {
// Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
?>

The file:
URL scheme refers to a file on the client machine. There is no hostname in the file:
scheme; you just provide the path of the file. So, the file on your local machine would be file:///~User/2ndFile.html
. Notice the three slashes; the hostname part of the URL is empty, so the slash at the beginning of the path immediately follows the double slash at the beginning of the URL. You will also need to expand the user's path; ~
does no expand in a file:
URL. So you would need file:///home/User/2ndFile.html
(on most Unixes), file:///Users/User/2ndFile.html
(on Mac OS X), or file:///C:/Users/User/2ndFile.html
(on Windows).
Many browsers, for security reasons, do not allow linking from a file that is loaded from a server to a local file. So, you may not be able to do this from a page loaded via HTTP; you may only be able to link to file:
URLs from other local pages.
For modern reference, in Symfony 2.4+, you cannot name the arguments for the Constructor Injection method anymore. According to the documentation You would pass in:
services:
test.common.userservice:
class: Test\CommonBundle\Services\UserService
arguments: [ "@doctrine.orm.entity_manager" ]
And then they would be available in the order they were listed via the arguments (if there are more than 1).
public function __construct(EntityManager $entityManager) {
$this->em = $entityManager;
}
Max has the best solution for when you always want to start both projects, but you can also right click a project and choose menu Debug ? Start New Instance.
This is an option when you only occasionally need to start the second project or when you need to delay the start of the second project (maybe the server needs to get up and running before the client tries to connect, or something).
Use the following query:
SELECT * FROM SAMPLE_TABLE ORDER BY ROWID ASC LIMIT 1

Using lodash unionWith function, you can accomplish a simple upsert to an object. The documentation states that if there is a match, it will use the first array. Wrap your updated object in [ ] (array) and put it as the first array of the union function. Simply specify your matching logic and if found it will replace it and if not it will add it
Example:
let contacts = [
{type: 'email', desc: 'work', primary: true, value: 'email prim'},
{type: 'phone', desc: 'cell', primary: true, value:'phone prim'},
{type: 'phone', desc: 'cell', primary: false,value:'phone secondary'},
{type: 'email', desc: 'cell', primary: false,value:'email secondary'}
]
// Update contacts because found a match
_.unionWith([{type: 'email', desc: 'work', primary: true, value: 'email updated'}], contacts, (l, r) => l.type == r.type && l.primary == r.primary)
// Add to contacts - no match found
_.unionWith([{type: 'fax', desc: 'work', primary: true, value: 'fax added'}], contacts, (l, r) => l.type == r.type && l.primary == r.primary)
Actually AnnotationConfigApplicationContext
derived from AbstractApplicationContext
, which has empty postProcessBeanFactory
method left for override
/**
* Modify the application context's internal bean factory after its standard
* initialization. All bean definitions will have been loaded, but no beans
* will have been instantiated yet. This allows for registering special
* BeanPostProcessors etc in certain ApplicationContext implementations.
* @param beanFactory the bean factory used by the application context
*/
protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) {
}
To leverage this, Create AnnotationConfigApplicationContextProvider
class which may look like following(given for Vertx
instance example, you can use MyClass
instead)...
public class CustomAnnotationApplicationContextProvider {
private final Vertx vertx;
public CustomAnnotationApplicationContextProvider(Vertx vertx) {
this.vertx = vertx;
}
/**

While creating ApplicationContext
you can create it using
Vertx vertx = ...; // either create or for vertx, it'll be passed to main verticle
ApplicationContext context = new CustomAnnotationApplicationContextProvider(vertx).get(ApplicationSpringConfig.class);
I had the same problem. But i discover that my hd is full.
$ sudo cat /var/log/upstart/mysql.log
/proc/self/fd/9: ERROR: The partition with /var/lib/mysql is too full!
So, I run
$ df -h
And I got the message
/dev/xvda1 7.8G 7.4G 0 100% /
Then I found out which folder was full by running the following command on the terminal
$ cd /var/www
$ for i in *; do echo $i; find $i |wc -l; done
This give me the number of files on each folder on /var/www. I logged into the folder with most files, and deleted some backup files, and i continued deleting useless files and cache files.
then I run $ sudo /etc/init.d/mysql start and it work again
Adapting this answer, you could do
df.ix[:,df.applymap(np.isreal).all(axis=0)]
Here, np.applymap(np.isreal)
shows whether every cell in the data frame is numeric, and .axis(all=0)
checks if all values in a column are True and returns a series of Booleans that can be used to index the desired columns.
This is a little tricky, the value you enter at keyboard, is a String value, so you have to pitch the first character with method line.chartAt(0)
where, 0 is the index of the first character, and store this value in a char variable as in char c= line.charAt(0)
now with the use of method isDigit()
and isLetter()
from class Character
you can differentiate between a Digit and Letter.
here is a code for your program:
import java.util.Scanner;
class Practice
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.println("Input a letter");
String line = in.nextLine();
char c = line.charAt(0);
if( Character.isDigit(c))
System.out.println(c +" Is a digit");
else if (Character.isLetter(c))
System.out.println(c +" Is a Letter");
}
}
I think your issue is jsfiddle
can process form-urlencoded
request only.
But correct way to make json request is pass correct json
as a body:
fetch('https://httpbin.org/post', {_x000D_
method: 'post',_x000D_
headers: {_x000D_
'Accept': 'application/json, text/plain, */*',_x000D_
'Content-Type': 'application/json'_x000D_
},_x000D_
body: JSON.stringify({a: 7, str: 'Some string: &=&'})_x000D_
}).then(res=>res.json())_x000D_
.then(res => console.log(res));
_x000D_
There is also a way of configuring Git so, it always pulls and pushes the equivalent remote branch to the branch currently checked out to the working copy. It's called a tracking branch which git ready recommends setting by default.
For the next repository above the present working directory:
git config branch.autosetupmerge true
For all Git repositories, that are not configured otherwise:
git config --global branch.autosetupmerge true
Kind of magic, IMHO but this might help in cases where the specific branch is always the current branch.
When you have branch.autosetupmerge
set to true
and checkout a branch for the first time, Git will tell you about tracking the corresponding remote branch:
(master)$ git checkout gh-pages
Branch gh-pages set up to track remote branch gh-pages from origin.
Switched to a new branch 'gh-pages'
Git will then push to that corresponding branch automatically:
(gh-pages)$ git push

First follow this procedure:
Log in on A as user a and generate a pair of authentication keys. Do not enter a passphrase:
a@A:~> ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/a/.ssh/id_rsa):
Created directory '/home/a/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/a/.ssh/id_rsa.
Your public key has been saved in /home/a/.ssh/id_rsa.pub.
The key fingerprint is:
3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a@A
Now use ssh to create a directory ~/.ssh as user b on B. (The directory may already exist, which is fine):
a@A:~> ssh b@B mkdir -p .ssh
b@B's password:
Finally append a's new public key to b@B:.ssh/authorized_keys and enter b's password one last time:
a@A:~> cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
b@B's password:
From now on you can log into B as b from A as a without password:
a@A:~> ssh b@B
then this will work without entering a password
ssh b@B "cd /some/directory; program-to-execute &"
Update your view with null value instead of parent viewgroup in Adapter viewholder onCreateViewHolder method.
@Override
public AdapterItemSku.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = inflator.inflate(R.layout.layout_item, null, false);
return new MyViewHolder(view);
}
Using def change
means you should write migrations that are reversible. And change_column
is not reversible. You can go up but you cannot go down, since change_column
is irreversible.
Instead, though it may be a couple extra lines, you should use def up
and def down
So if you have a column with no default value, then you should do this to add a default value.
def up
change_column :users, :admin, :boolean, default: false
end
def down
change_column :users, :admin, :boolean, default: nil
end
Or if you want to change the default value for an existing column.
def up
change_column :users, :admin, :boolean, default: false
end
def down
change_column :users, :admin, :boolean, default: true
end
Unless you can get PHP to label that element with a class you are better to use jQuery.
jQuery(document).ready(function () {
$count = jQuery("ul li").size() - 1;
alert($count);
jQuery("ul li:nth-child("+$count+")").css("color","red");
});
This is how to use chai to deeply test associative arrays.
I had an issue trying to assert that two associative arrays were equal. I know that these shouldn't really be used in javascript but I was writing unit tests around legacy code which returns a reference to an associative array. :-)
I did it by defining the variable as an object (not array) prior to my function call:
var myAssocArray = {}; // not []
var expectedAssocArray = {}; // not []
expectedAssocArray['myKey'] = 'something';
expectedAssocArray['differentKey'] = 'something else';
// legacy function which returns associate array reference
myFunction(myAssocArray);
assert.deepEqual(myAssocArray, expectedAssocArray,'compare two associative arrays');
This comment from verybadbug under question helped me:
ln -s /etc/apache2/mods-available/rewrite.load /etc/apache2/mods-enabled/rewrite.load
After that we need restart Apache:
sudo service apache2 restart
TL;DR:
In simple words, bind creates the function, call and apply executes the function whereas apply expects the parameters in array
Full Explanation
Assume we have multiplication
function
function multiplication(a,b){
console.log(a*b);
}
Lets create some standard functions using bind
var multiby2 = multiplication.bind(this,2);
Now multiby2(b) is equal to multiplication(2,b);
multiby2(3); //6
multiby2(4); //8
What if I pass both the parameters in bind
var getSixAlways = multiplication.bind(this,3,2);
Now getSixAlways() is equal to multiplication(3,2);
getSixAlways();//6
even passing parameter returns 6;
getSixAlways(12); //6
var magicMultiplication = multiplication.bind(this);
This create a new multiplication function and assigns it to magicMultiplication.
Oh no, we are hiding the multiplication functionality into magicMultiplication.
calling
magicMultiplication
returns a blank function b()
on execution it works fine
magicMultiplication(6,5); //30
How about call and apply?
magicMultiplication.call(this,3,2); //6
magicMultiplication.apply(this,[5,2]); //10
Sample code for How to get text from EditText
.
Android Java Syntax
EditText text = (EditText)findViewById(R.id.vnosEmaila);
String value = text.getText().toString();
Kotlin Syntax
val text = findViewById<View>(R.id.vnosEmaila) as EditText
val value = text.text.toString()
One tweak to all of these answers:
var routes = fs.readdirSync('routes')
.filter(function(v){
return (/.js$/).test(v);
});
Just use a regex to filter via testing each file in the array. It is not recursive, but it will filter out folders that don't end in .js
Better to use:
DELETE tbl FROM tbl INNER JOIN deleted ON tbl.key=deleted.key
Simple check to see if two time periods overlap:
bool overlap = a.start < b.end && b.start < a.end;
or in your code:
bool overlap = tStartA < tEndB && tStartB < tEndA;
(Use <=
instead of <
if you change your mind about wanting to say that two periods that just touch each other overlap.)
I didn't go down the road of getting new DLL's. We had a bunch of existing projects that work perfectly fine and it was only my new project that was giving me headache so I decided to try something else.
My project was using an internally developed Internal.dll that depended on Oracle.DataAccess.dll v4.112.3.0
. For some reason, when publishing, Visual Studio always uploaded v4.121.0.0
, even though it wasn't explicitly specified in any of the config files. That's why I was getting an error.
So what I did was:
/bin
(just to be on the safe side)./bin
.myWebSite.csproj
, but it showed the wrong version: v4.121.0.0
instead of v4.112.3.0
.I manually changed the reference in myWebSite.csproj
, so it now read:
<Reference Include="Oracle.DataAccess, Version=4.112.3.0, Culture=neutral, PublicKeyToken=89b483f429c47342, processorArchitecture=x86">
<SpecificVersion>False</SpecificVersion>
<HintPath>bin\Oracle.DataAccess.dll</HintPath>
</Reference>
