I guess what you need is np.set_printoptions(suppress=True)
, for details see here:
http://pythonquirks.blogspot.fr/2009/10/controlling-printing-in-numpy.html
For SciPy.org numpy documentation, which includes all function parameters (suppress isn't detailed in the above link), see here: https://docs.scipy.org/doc/numpy/reference/generated/numpy.set_printoptions.html
The behavior you're seeing is due to how ggplot2
deals with data that are outside the axis ranges of the plot. You can change this behavior depending on whether you use scale_y_continuous
(or, equivalently, ylim
) or coord_cartesian
to set axis ranges, as explained below.
library(ggplot2)
# All points are visible in the plot
ggplot(mtcars, aes(mpg, hp)) +
geom_point()
In the code below, one point with hp = 335 is outside the y-range of the plot. Also, because we used scale_y_continuous
to set the y-axis range, this point is not included in any other statistics or summary measures calculated by ggplot, such as the linear regression line.
ggplot(mtcars, aes(mpg, hp)) +
geom_point() +
scale_y_continuous(limits=c(0,300)) + # Change this to limits=c(0,335) and the warning disappars
geom_smooth(method="lm")
Warning messages:
1: Removed 1 rows containing missing values (stat_smooth).
2: Removed 1 rows containing missing values (geom_point).
In the code below, the point with hp = 335 is still outside the y-range of the plot, but this point is nevertheless included in any statistics or summary measures that ggplot calculates, such as the linear regression line. This is because we used coord_cartesian
to set the y-axis range, and this function does not exclude points that are outside the plot ranges when it does other calculations on the data.
If you compare this and the previous plot, you can see that the linear regression line in the second plot has a slightly steeper slope, because the point with hp=335 is included when calculating the regression line, even though it's not visible in the plot.

I decided to change comma to dot only while editing. Here is my tricky and relative simple workaround:
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
EditText editText = (EditText) v;
String text = editText.getText().toString();
if (hasFocus) {
editText.setText(text.replace(",", "."));
} else {
if (!text.isEmpty()) {
Double doubleValue = Double.valueOf(text.replace(",", "."));
editText.setText(someDecimalFormatter.format(doubleValue));
}
}
}
});
someDecimalFormatter will use comma or dot depends on Locale
In case you want to create your own Test Class. In Eclipse go to File -> New -> J Unit Test Case. You can then choose all your paths and testing class setup within the wizard pop-up.
For small projects I find it easiest to work with tuples. When that gets too hard to manage (and not before) I start grouping things into logical structures, however I think your suggested use of dictionaries and ReturnValue
objects is wrong (or too simplistic).
Returning a dictionary with keys "y0"
, "y1"
, "y2"
, etc. doesn't offer any advantage over tuples. Returning a ReturnValue
instance with properties .y0
, .y1
, .y2
, etc. doesn't offer any advantage over tuples either. You need to start naming things if you want to get anywhere, and you can do that using tuples anyway:
def get_image_data(filename):
[snip]
return size, (format, version, compression), (width,height)
size, type, dimensions = get_image_data(x)
IMHO, the only good technique beyond tuples is to return real objects with proper methods and properties, like you get from re.match()
or open(file)
.
just use getCheckedRadioButtonId() function to determine wether if anything is checked, if -1 is return, you can avoid toast appear
According to the GF Administration Guide:
For a valid JVM installation, locations are checked in the following order: a. domain.xml (java-home inside java-config) b. asenv.conf (setting AS_JAVA="path to java home")
I had to add both these settings to make it work. Otherwise 'asadmin stop-domain domain1' wouldn't work. I guess that GF uses a. and asadmin uses b.
(On Windows: b. asenv.bat)
This Works For me !!!
Call a Function without Parameter
$("#CourseSelect").change(function(e1) {
loadTeachers();
});
Call a Function with Parameter
$("#CourseSelect").change(function(e1) {
loadTeachers($(e1.target).val());
});
If it's open to a modification, you could use a suffix instead of a prefix. Then you could use tab-completion to get the original filename and add the suffix.
Otherwise, no this isn't something that is supported by the mv command. A simple shell script could cope though.
I use android studio 0.8.6 and for importing external library in project , paste that library in libs folder and inside build.gradle write path of that library inside dependencies like this compile files('libs/google-play-services.jar')
Once gdb
starts, you can run the program using "r args".
So if you are running your code by:
$ executablefile arg1 arg2 arg3
Debug it on gdb
by:
$ gdb executablefile
(gdb) r arg1 arg2 arg3
Make sure you do this first
git fetch
Once you have all remote branches information, use the following command to remove every single branch except master
git branch -a | grep -v "master" | grep remotes | sed 's/remotes\/origin\///g' | xargs git push origin --delete

If you give a default value to each primary constructor parameter:
data class Item(var id: String = "",
var title: String = "",
var condition: String = "",
var price: String = "",
var categoryId: String = "",
var make: String = "",
var model: String = "",
var year: String = "",
var bodyStyle: String = "",
var detail: String = "",
var latitude: Double = 0.0,
var longitude: Double = 0.0,
var listImages: List<String> = emptyList(),
var idSeller: String = "")
and from the class where the instances you can call it without arguments or with the arguments that you have that moment
var newItem = Item()
var newItem2 = Item(title = "exampleTitle",
condition = "exampleCondition",
price = "examplePrice",
categoryId = "exampleCategoryId")
I would try using netem on linux. With it you can simulate additional delay, corruption, packet loss and duplication. It even works on the loopback device.
Just use
filter_input(INPUT_METHOD_NAME, 'var_name')
instead of $_INPUT_METHOD_NAME['var_name']
filter_input_array(INPUT_METHOD_NAME)
instead of $_INPUT_METHOD_NAME
e.g
$host= filter_input(INPUT_SERVER, 'HTTP_HOST');
echo $host;
instead of
$host= $_SERVER['HTTP_HOST'];
echo $host;
And use
var_dump(filter_input_array(INPUT_SERVER));
instead of
var_dump($_SERVER);
N.B: Apply to all other Super Global variable
Updated answer for ES6+ is here.
arr = [1, 2, 3];
arr.forEach(function(i, idx, array){
if (idx === array.length - 1){
console.log("Last callback call at index " + idx + " with value " + i );
}
});
would output:
Last callback call at index 2 with value 3
The way this works is testing arr.length
against the current index of the array, passed to the callback function.
give this style to td: width: 1%;
First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local
.
Another simple way is to use @reboot
in your crontab. Read the cron manpage for details.
However, if you want to do things properly, in addition to adding a script to /etc/init.d
you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d
which creates a symlink from some of the /etc/rc*
directories to your script. So, you'd need to do something like:
update-rc.d yourscriptname start 2
However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README
has some details and further pointers.
There's a way to access this information through the GitHub API.
GET /repos/:user/:repo
When retrieving information about a repository, a property named size
is valued with the size of the whole repository (including all of its history), in kilobytes.
For instance, the Git repository weights around 124 MB. The size
property of the returned JSON payload is valued to 124283
.
The size is indeed expressed in kilobytes based on the disk usage of the server-side bare repository. However, in order to avoid wasting too much space with repositories with a large network, GitHub relies on Git Alternates. In this configuration, calculating the disk usage against the bare repository doesn't account for the shared object store and thus returns an "incomplete" value through the API call.
This information has been given by GitHub support.
You're not using splice correctly:
arr.splice(4, 1)
this will remove 1 item at index 4. see here
I think you want to use slice:
arr.slice(0,5)
this will return elements in position 0 through 4.
This assumes all the rest of your code (cookies etc) works correctly
Using detach is magnitudes faster than any of the other answers here:
$('#mytable').find('tbody').detach();
Don't forget to put the tbody element back into the table since detach removed it:
$('#mytable').append($('<tbody>'));
Also note that when talking efficiency $(target).find(child)
syntax is faster than $(target > child)
. Why? Sizzle!
Elapsed Time to Empty 3,161 Table Rows
Using the Detach() method (as shown in my example above):
Using the empty() method:
You opened a lot of connections and that's the issue. I think in your code, you did not close the opened connection.
A database bounce could temporarily solve, but will re-appear when you do consecutive execution. Also, it should be verified the number of concurrent connections to the database. If maximum DB processes parameter has been reached this is a common symptom.
Courtesy of this thread: https://community.oracle.com/thread/362226?tstart=-1
I like these two because they seem the most logical, the latter being shorter and probably fastest (shown here using set
literal syntax which has been backported to Python 2.7):
all(x in {'a', 'b', 'c'} for x in ['a', 'b'])
# or
{'a', 'b'}.issubset({'a', 'b', 'c'})

For a unique column, use this:
INSERT OR REPLACE INTO table () values();
For more information, see: sqlite.org/lang_insert
You can set the caret position using TextBox.CaretIndex. If the only thing you need is to set the cursor at the end, you can simply pass the string's length, eg:
txtBox.CaretIndex=txtBox.Text.Length;
You need to set the caret index at the length, not length-1, because this would put the caret before the last character.
Here it was the "Work Folders" feature having been added on a Server 2012 R2. By default it is listening for HTTPS client requests on port 443 via the "System" process. There is a Technet blog post explaining how to change that port number. Don't forget to add a corresponding firewall rule for your custom port and disable the existing one for port 443 though.

The second part of your question is answered well. Here is the answer for the first part: How to output multiple files with webpack:
entry: {
outputone: './source/fileone.jsx',
outputtwo: './source/filetwo.jsx'
},
output: {
path: path.resolve(__dirname, './wwwroot/js/dist'),
filename: '[name].js'
},
This will generate 2 files: outputone.js und outputtwo.js in the target folder.
The Following:
.show-grid [class*="span"] {
means that all child elements of '.show-grid' with a class that CONTAINS the word 'span' in it will acquire those CSS properties.
<div class="show-grid">
<div class="span">.span</div>
<div class="span6">span6</div>
<div class="attention-span">attention</div>
<div class="spanish">spanish</div>
<div class="mariospan">mariospan</div>
<div class="espanol">espanol</div>
<div>
<div class="span">.span</div>
</div>
<p class="span">span</p>
<span class="span">I do GET HIT</span>
<span>I DO NOT GET HIT since I need a class of 'span'</span>
</div>
<div class="span">I DO NOT GET HIT since I'm outside of .show-grid</span>
All of the elements get hit except for the <span>
by itself.
In Regards to Bootstrap:
span6
: this was Bootstrap 2's scaffolding technique which divided a section into a horizontal grid, based on parts of 12. Thus span6
would have a width of 50%..col-*
classes (e.g. col-sm-6
), which also specifies a media breakpoint to handle responsiveness when the window shrinks below a certain size. Check Bootstrap 4.1 and Bootstrap 3.3.7 for more documentation. I would recommend going with a later Bootstrap nowadaysFrom here.
If you create a file in your repo named .gitignore git will use its rules when looking at files to commit. Note that git will not ignore a file that was already tracked before a rule was added to this file to ignore it. In such a case the file must be un-tracked, usually with :
git rm --cached filename
Is it your case ?
Easiest solution is:
const todayDate = Date.now();
return new Date(todayDate + 1000 * 60 * 60 * 24 * 30* X);
where X
is the number of months we want to add.
The accepted answer looks way too complex to me so I am adding a Ruby and NodeJS versions of it
Suppose that flat nodes list have the following structure:
nodes = [
{ id: 7, parent_id: 1 },
...
] # ruby
nodes = [
{ id: 7, parentId: 1 },
...
] # nodeJS
The functions which will turn the flat list structure above into a tree look the following way
for Ruby:
def to_tree(nodes)
nodes.each do |node|
parent = nodes.find { |another| another[:id] == node[:parent_id] }
next unless parent
node[:parent] = parent
parent[:children] ||= []
parent[:children] << node
end
nodes.select { |node| node[:parent].nil? }
end
for NodeJS:
const toTree = (nodes) => {
nodes.forEach((node) => {
const parent = nodes.find((another) => another.id == node.parentId)
if(parent == null) return;
node.parent = parent;
parent.children = parent.children || [];
parent.children = parent.children.concat(node);
});
return nodes.filter((node) => node.parent == null)
};
It is important to be specific about what exception you're trying to catch when using a try/except block.
string = "abcd"
try:
string_int = int(string)
print(string_int)
except ValueError:
# Handle the exception
print('Please enter an integer')
Try/Excepts are powerful because if something can fail in a number of different ways, you can specify how you want the program to react in each fail case.
Html.DisplayFor()
will render the DisplayTemplate that matches the property's type.
If it can't find any, I suppose it invokes .ToString()
.
If you don't know about display templates, they're partial views that can be put in a DisplayTemplates
folder inside the view folder associated to a controller.
Example:
If you create a view named String.cshtml
inside the DisplayTemplates
folder of your views folder (e.g Home
, or Shared
) with the following code:
@model string
@if (string.IsNullOrEmpty(Model)) {
<strong>Null string</strong>
}
else {
@Model
}
Then @Html.DisplayFor(model => model.Title)
(assuming that Title
is a string) will use the template and display <strong>Null string</strong>
if the string is null, or empty.
Whether to open the URL in a new tab or a new window, is actually controlled by the user's browser preferences. There is no way to override it in JavaScript.
window.open()
behaves differently depending on how it is being used. If it is called as a direct result of a user action, let us say a button click, it should work fine and open a new tab (or window):
const button = document.querySelector('#openTab');
// add click event listener
button.addEventListener('click', () => {
// open a new tab
const tab = window.open('https://attacomsian.com', '_blank');
});
However, if you try to open a new tab from an AJAX request callback, the browser will block it as it was not a direct user action.
To bypass the popup blocker and open a new tab from a callback, here is a little hack:
const button = document.querySelector('#openTab');
// add click event listener
button.addEventListener('click', () => {
// open an empty window
const tab = window.open('about:blank');
// make an API call
fetch('/api/validate')
.then(res => res.json())
.then(json => {
// TODO: do something with JSON response
// update the actual URL
tab.location = 'https://attacomsian.com';
tab.focus();
})
.catch(err => {
// close the empty window
tab.close();
});
});
The problem is that Chrome needs to have must-revalidate
in the Cache-Control` header in order to re-check files to see if they need to be re-fetched.
You can always SHIFT-F5 and force Chrome to refresh, but if you want to fix this problem on the server, include this response header:
Cache-Control: must-revalidate
This tells Chrome to check with the server, and see if there is a newer file. IF there is a newer file, it will receive it in the response. If not, it will receive a 304 response, and the assurance that the one in the cache is up to date.
If you do NOT set this header, then in the absence of any other setting that invalidates the file, Chrome will never check with the server to see if there is a newer version.
Here is a blog post that discusses the issue further.

I have faced this type of error. to call a function from the razor.
public ActionResult EditorAjax(int id, int? jobId, string type = ""){}
solved that by changing the line
from
<a href="/ScreeningQuestion/EditorAjax/5&jobId=2&type=additional" />
to
<a href="/ScreeningQuestion/EditorAjax/?id=5&jobId=2&type=additional" />
where my route.config is
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }, new string[] { "RPMS.Controllers" } // Parameter defaults
);

If I understood you right, you want to copy $var
in a file (if it's a string).
echo $var > $destdir
using ylim() might be the best approach for your purpose:
xValues = list(range(10))
quads = [x** 2 for x in xValues]
plt.ylim(max(quads), 0)
plt.plot(xValues, quads)
jQuery datepicker
is good option
There are different ways to measure the height depending on what you need.
If you are doing something like precisely centering a small amount of fixed text, you probably want getTextBounds
. You can get the bounding rectangle like this
Rect bounds = new Rect();
mTextPaint.getTextBounds(mText, 0, mText.length(), bounds);
int height = bounds.height();
As you can see for the following images, different strings will give different heights (shown in red).
These differing heights could be a disadvantage in some situations when you just need a constant height no matter what the text is. See the next section.
You can calculate the hight of the font from the font metrics. The height is always the same because it is obtained from the font, not any particular text string.
Paint.FontMetrics fm = mTextPaint.getFontMetrics();
float height = fm.descent - fm.ascent;
The baseline is the line that the text sits on. The descent is generally the furthest a character will go below the line and the ascent is generally the furthest a character will go above the line. To get the height you have to subtract ascent because it is a negative value. (The baseline is y=0
and y
descreases up the screen.)
Look at the following image. The heights for both of the strings are 234.375
.
If you want the line height rather than just the text height, you could do the following:
float height = fm.bottom - fm.top + fm.leading; // 265.4297
These are the bottom
and top
of the line. The leading (interline spacing) is usually zero, but you should add it anyway.
The images above come from this project. You can play around with it to see how Font Metrics work.
For measuring the height of multi-line text you should use a StaticLayout
. I talked about it in some detail in this answer, but the basic way to get this height is like this:
String text = "This is some text. This is some text. This is some text. This is some text. This is some text. This is some text.";
TextPaint myTextPaint = new TextPaint();
myTextPaint.setAntiAlias(true);
myTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
myTextPaint.setColor(0xFF000000);
int width = 200;
Layout.Alignment alignment = Layout.Alignment.ALIGN_NORMAL;
float spacingMultiplier = 1;
float spacingAddition = 0;
boolean includePadding = false;
StaticLayout myStaticLayout = new StaticLayout(text, myTextPaint, width, alignment, spacingMultiplier, spacingAddition, includePadding);
float height = myStaticLayout.getHeight();
The most important difference is that robocopy
will (usually) retry when an error occurs, while xcopy
will not. In most cases, that makes robocopy
far more suitable for use in a script.
Addendum: for completeness, there is one known edge case issue with robocopy; it may silently fail to copy files or directories whose names contain invalid UTF-16 sequences. If that's a problem for you, you may need to look at third-party tools, or write your own.
Problem Cause : The process of the current program is still running without interuption. (This is the reason why you haven't got this issue after a restart)
The fix is simple : Go to cmd and type the command taskkill -im process-name.exe -f
Eg:
taskkill -im demo.exe -f
here,
demo - is my program name
Similar to Dictionary Collection point of view, I have done this.
Dictionary<string, bool> sourceDict = new Dictionary<string, bool>();
sourceDict.Add("Sai", true);
sourceDict.Add("Sri", false);
sourceDict.Add("SaiSri", true);
sourceDict.Add("SaiSriMahi", true);
var itemsToDelete = sourceDict.Where(DictItem => DictItem.Value == false);
foreach (var item in itemsToDelete)
{
sourceDict.Remove(item.Key);
}
Note: Above code will fail in .Net Client Profile (3.5 and 4.5) also some viewers mentioned it is Failing for them in .Net4.0 as well not sure which settings are causing the problem.
So replace with below code (.ToList()) for Where statement, to avoid that error. “Collection was modified; enumeration operation may not execute.”
var itemsToDelete = sourceDict.Where(DictItem => DictItem.Value == false).ToList();
Per MSDN From .Net4.5 onwards Client Profile are discontinued. http://msdn.microsoft.com/en-us/library/cc656912(v=vs.110).aspx
The answer is correct, but you don't need to declare a variable. A string can contain your character:
"This string contains omega, that looks like this: \u03A9"
Unfortunately still those codes in ASCII are needed for displaying UTF-8, but I am still waiting (since too many years...) the day when UTF-8 will be same as ASCII was, and ASCII will be just a remembrance of the past.
You can do this with pure CSS but you will need to hard code the offset scroll amounts, which may not be ideal should you be changing page content- or should dimensions of your content change on say window resize.
You're likely best placed to use e.g. jQuery, specifically:
$('html, body').stop().animate({
scrollTop: element.offset().top
}, 1000);
A complete implementation may be:
$('#up, #down').on('click', function(e){
e.preventDefault();
var target= $(this).get(0).id == 'up' ? $('#down') : $('#up');
$('html, body').stop().animate({
scrollTop: target.offset().top
}, 1000);
});
Where element
is the target element to scroll to and 1000
is the delay in ms before completion.
The benefit being, no matter what changes to your content dimensions, the function will not need to be altered.
The long boring solution, which is not involved with CLI, you can manually navigate to:
your local repo folder ? .git folder (hidden) ? config file
then choose your text editor to open it and look for url located under the [remote "origin"] section.
VBA is not VB/VB.NET
The correct reference to use is Do..Loop Statement (VBA). Also see the article Excel VBA For, Do While, and Do Until. One way to write this is:
Do While counter < 20
counter = counter + 1
Loop
(But a For..Next might be more appropriate here.)
Happy coding.
If I understand correctly, you want to have one class implement multiple of those interfaces with different input/output parameters? This will not work in Java, because the generics are implemented via erasure.
The problem with the Java generics is that the generics are in fact nothing but compiler magic. At runtime, the classes do not keep any information about the types used for generic stuff (class type parameters, method type parameters, interface type parameters). Therefore, even though you could have overloads of specific methods, you cannot bind those to multiple interface implementations which differ in their generic type parameters only.
In general, I can see why you think that this code has a smell. However, in order to provide you with a better solution, it would be necessary to know a little more about your requirements. Why do you want to use a generic interface in the first place?
None of you guys are answering his question.
with this code i get the same sequance everytime the code but it generates random sequences if i add srand(/somevalue/) before the for loop . can someone explain why ?
From what my professor has told me, it is used if you want to make sure your code is running properly and to see if there is something wrong or if you can change something.
Try this. It will check to see if the file already exists in the destination folder, and if it does will check if the file is read-only. If the file is read-only it will change it to read-write, replace the file, and make it read-only again.
Const DestinationFile = "c:\destfolder\anyfile.txt"
Const SourceFile = "c:\sourcefolder\anyfile.txt"
Set fso = CreateObject("Scripting.FileSystemObject")
'Check to see if the file already exists in the destination folder
If fso.FileExists(DestinationFile) Then
'Check to see if the file is read-only
If Not fso.GetFile(DestinationFile).Attributes And 1 Then
'The file exists and is not read-only. Safe to replace the file.
fso.CopyFile SourceFile, "C:\destfolder\", True
Else
'The file exists and is read-only.
'Remove the read-only attribute
fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes - 1
'Replace the file
fso.CopyFile SourceFile, "C:\destfolder\", True
'Reapply the read-only attribute
fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes + 1
End If
Else
'The file does not exist in the destination folder. Safe to copy file to this folder.
fso.CopyFile SourceFile, "C:\destfolder\", True
End If
Set fso = Nothing
Just a few points for completeness:
this answer is discussing only integer representations. There may be other answers for floating point;
the representation of a negative number can vary. The most common (by far - it's nearly universal today) in use today is two's complement. Other representations include one's complement (quite rare) and signed magnitude (vanishingly rare - probably only used on museum pieces) which is simply using the high bit as a sign indicator with the remain bits representing the absolute value of the number.
When using two's complement, the variable can represent a larger range (by one) of negative numbers than positive numbers. This is because zero is included in the 'positive' numbers (since the sign bit is not set for zero), but not the negative numbers. This means that the absolute value of the smallest negative number cannot be represented.
when using one's complement or signed magnitude you can have zero represented as either a positive or negative number (which is one of a couple of reasons these representations aren't typically used).
Give your parent div position: relative
, then give your child div position: absolute
, this will absolute position the div inside of its parent, then you can give the child bottom: 0px;

Read up on Cancellation (which was introduced in .NET 4.0 and is largely unchanged since then) and the Task-Based Asynchronous Pattern, which provides guidelines on how to use CancellationToken
with async
methods.
To summarize, you pass a CancellationToken
into each method that supports cancellation, and that method must check it periodically.
private async Task TryTask()
{
CancellationTokenSource source = new CancellationTokenSource();
source.CancelAfter(TimeSpan.FromSeconds(1));
Task<int> task = Task.Run(() => slowFunc(1, 2, source.Token), source.Token);
// (A canceled task will raise an exception when awaited).
await task;
}
private int slowFunc(int a, int b, CancellationToken cancellationToken)
{
string someString = string.Empty;
for (int i = 0; i < 200000; i++)
{
someString += "a";
if (i % 1000 == 0)
cancellationToken.ThrowIfCancellationRequested();
}
return a + b;
}

ArrayAdapter uses a TextView to display each item within it. Behind the scenes, it uses the toString()
method of each object that it holds and displays this within the TextView. ArrayAdapter has a number of constructors that can be used and the one that you have used in your example is:
ArrayAdapter(Context context, int resource, int textViewResourceId, T[] objects)
By default, ArrayAdapter uses the default TextView to display each item. But if you want, you could create your own TextView and implement any complex design you'd like by extending the TextView class. This would then have to go into the layout for your use. You could reference this in the textViewResourceId field to bind the objects to this view instead of the default.
For your use, I would suggest that you use the constructor:
ArrayAdapter(Context context, int resource, T[] objects).
In your case, this would be:
ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, values)
and it should be fine. This will bind each string to the default TextView display - plain and simple white background.
So to answer your question, you do not have to use the textViewResourceId.
What about using PRIOR,
so
SELECT id, parent_id, PRIOR name
FROM tbl
START WITH id = 1
CONNECT BY PRIOR id = parent_id`
or if you want to get the root name
SELECT id, parent_id, CONNECT_BY_ROOT name
FROM tbl
START WITH id = 1
CONNECT BY PRIOR id = parent_id
Adding skipLibCheck: true
in compilerOptions
inside tsconfig.json
file fixed my issue.
"compilerOptions": {

You can quickly convert deeply nested objects to associative arrays by relying on the behavior of the JSON encode/decode functions:
$array = json_decode(json_encode($response->response->docs), true);

Sometimes we want to catch a SIGSEGV
to find out if a pointer is valid, that is, if it references a valid memory address. (Or even check if some arbitrary value may be a pointer.)
One option is to check it with isValidPtr()
(worked on Android):
int isValidPtr(const void*p, int len) {
if (!p) {
return 0;
}
int ret = 1;
int nullfd = open("/dev/random", O_WRONLY);
if (write(nullfd, p, len) < 0) {
ret = 0;
/* Not OK */
}
close(nullfd);
return ret;
}
int isValidOrNullPtr(const void*p, int len) {
return !p||isValidPtr(p, len);
}
Another option is to read the memory protection attributes, which is a bit more tricky (worked on Android):

Ok, instead of identifying players by name track with sockets through which they have connected. You can have a implementation like
var allClients = [];
io.sockets.on('connection', function(socket) {
allClients.push(socket);
socket.on('disconnect', function() {
console.log('Got disconnect!');
var i = allClients.indexOf(socket);
allClients.splice(i, 1);
});
});
Hope this will help you to think in another way

First backup the database. Then drop any foreign key associated with the table. truncate the foreign key table.Truncate the current table. Remove the required primary keys. Use sqlyog or workbench or heidisql or dbeaver or phpmyadmin.
Since x!=x
returns the same boolean array with np.isnan(x)
(because np.nan!=np.nan
would return True
), you could also write:
np.argwhere(x!=x)
However, I still recommend writing np.argwhere(np.isnan(x))
since it is more readable. I just try to provide another way to write the code in this answer.
Can't beat Eric Leschinski's awesomely detailed answer, but here's a quick workaround to the original question that I don't think has been mentioned yet - put the string in a list and use .isin
instead of ==
For example:
import pandas as pd
import numpy as np
df = pd.DataFrame({"Name": ["Peter", "Joe"], "Number": [1, 2]})
# Raises warning using == to compare different types:
df.loc[df["Number"] == "2", "Number"]
# No warning using .isin:
df.loc[df["Number"].isin(["2"]), "Number"]

I was already installed Android Studio and it's just need to add gradle PATH to ~/.bash_profile on my MacOSX Mojave. Also if gradle is upgraded then path might need to update again.
Example .bash_profile :
export ANDROID_SDK_ROOT="~/Library/Android/sdk"
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
export JAVA_HOME=$(/usr/libexec/java_home)
export GRADLE_PATH="~/.gradle/wrapper/dists/gradle-4.10.1-all/455itskqi2qtf0v2sja68alqd/gradle-4.10.1/bin"
export ANDROID_STUDIO="/Applications/Android Studio.app/Contents/MacOS"
export PATH="$PATH:$GRADLE_PATH:$ANDROID_STUDIO"
When edited your .bash_profile then run a command below to read it again.
source ~/.bash_profile
No, but browser auto-complete is often triggered by the field having the same name
attribute as fields that were previously filled out. If you could rig up a clever way to have a randomized field name, autocomplete wouldn't be able to pull any previously entered values for the field.
If you were to give an input field a name like "email_<?= randomNumber() ?>
", and then have the script that receives this data loop through the POST or GET variables looking for something matching the pattern "email_[some number]
", you could pull this off, and this would have (practically) guaranteed success, regardless of browser.
It's important to note, that NULL doesn't equal NULL.
NULL
is not a value, and therefore cannot be compared to another value.
where x is null
checks whether x is a null value.
where x = null
is checking whether x equals NULL, which will never be true
Acording to your first code snipet seems ok, but I've got similar behavior caused by bad programing. Have you checked the "options" variable is not null before the put call?

*In all instances the # refers to the cell number
You really don't need the datedif functions; for example:
I'm working on a spreadsheet that tracks benefit eligibility for employees.
I have their hire dates in the "A" column and in column B is =(TODAY()-A#)
And you just format the cell to display a general number instead of date.
It also works very easily the other way: I also converted that number into showing when the actual date is that they get their benefits instead of how many days are left, and that is simply
=(90-B#)+TODAY()
Just make sure you're formatting cells as general numbers or dates accordingly.
Hope this helps.
Here goes a straightforward example:
# Do something, or tell me why it failed
my_update_function <- function(x){
tryCatch(
# This is what I want to do...
{
y = x * 2
return(y)
},
# ... but if an error occurs, tell me what happened:
error=function(error_message) {
message("This is my custom message.")
message("And below is the error message from R:")
message(error_message)
return(NA)
}
)
}
If you also want to capture a "warning", just add warning=
similar to the error=
part.

You shouldn´t use client javascript to access databases for several reasons (bad practice, security issues, etc) but if you really want to do this, here is an example:
var connection = new ActiveXObject("ADODB.Connection") ;
var connectionstring="Data Source=<server>;Initial Catalog=<catalog>;User ID=<user>;Password=<password>;Provider=SQLOLEDB";
connection.Open(connectionstring);
var rs = new ActiveXObject("ADODB.Recordset");
rs.Open("SELECT * FROM table", connection);
rs.MoveFirst
while(!rs.eof)
{
document.write(rs.fields(1));
rs.movenext;
}
rs.close;
connection.close;
A better way to connect to a sql server would be to use some server side language like PHP, Java, .NET, among others. Client javascript should be used only for the interfaces.
And there are rumors of an ancient legend about the existence of server javascript, but this is another story. ;)
I have stumbled across this question and I will submit my answer that I used and worked pretty well. I had a search box that filtered and array of objects and on my search box I used the (ngModelChange)="onChange($event)"
in my .html
<input type="text" [(ngModel)]="searchText" (ngModelChange)="reSearch(newValue)" placeholder="Search">
then in my component.ts
reSearch(newValue: string) {
//this.searchText would equal the new value
//handle my filtering with the new value
}
You can use some div or span instead of button and then on click call some function which submits form at he end.
<form id="my_form">
<span onclick="submit()">submit</span>
</form>
<script>
function submit()
{
//do something
$("#my_form").submit();
}
</script>
In Python 3, print
became a function. This means that you need to include parenthesis now like mentioned below:
print("Hello World")
You could simply use
return
which does exactly the same as
return None
Your function will also return None
if execution reaches the end of the function body without hitting a return
statement. Returning nothing is the same as returning None
in Python.
Even if we interchange @Component or @Repository or @service
It will behave the same , but one aspect is that they wont be able to catch some specific exception related to DAO instead of Repository if we use component or @ service
The reason this question still often arises is because, as you mentioned, somewhere somehow someone presumed as important wrote that the RFC states domain names without subdomain in front of them are not valid. If you read the RFC carefully, however, you'll find that this is not exactly what it says. In fact, RFC 1912 states:
Don't go overboard with CNAMEs. Use them when renaming hosts, but plan to get rid of them (and inform your users).
Some DNS hosts provide a way to get CNAME-like functionality at the zone apex (the root domain level, for the naked domain name) using a custom record type. Such records include, for example:
For each provider, the setup is similar: point the ALIAS or ANAME entry for your apex domain to example.domain.com, just as you would with a CNAME record. Depending on the DNS provider, an empty or @ Name value identifies the zone apex.
ALIAS or ANAME or @ example.domain.com.
If your DNS provider does not support such a record-type, and you are unable to switch to one that does, you will need to use subdomain redirection, which is not that hard, depending on the protocol or server software that needs to do it.
I strongly disagree with the statement that it's done only by "amateur admins" or such ideas. It's a simple "What does the name and its service need to do?" deal, and then to adapt your DNS config to serve those wishes; If your main services are web and e-mail, I don' t see any VALID reason why dropping the CNAMEs for-good would be problematic. After all, who would prefer @subdomain.domain.org over @domain.org ? Who needs "www" if you're already set with the protocol itself? It's illogical to assume that use of a root-domainname would be invalid.
If you are using jQuery 1.2 or newer, you can simply use these:
$(window).width();
$(document).width();
$(window).height();
$(document).height();
From there it is a simple matter to decide the height of your element.

This may be created sql injection point "SQL Injection Piggy-backed Queries". attackers able to append multiple malicious sql statements. so do not append user inputs directly to the queries.
Security considerations
The API functions mysqli_query() and mysqli_real_query() do not set a connection flag necessary for activating multi queries in the server. An extra API call is used for multiple statements to reduce the likeliness of accidental SQL injection attacks. An attacker may try to add statements such as ; DROP DATABASE mysql or ; SELECT SLEEP(999). If the attacker succeeds in adding SQL to the statement string but mysqli_multi_query is not used, the server will not execute the second, injected and malicious SQL statement.
You may want to check your config to see if the bind_ip is set
bind_ip: 127.0.0.1
If it is then this permits only local logins. Comment this out and restart mongo, this may help.
You have three possibilites:
(new RegExp('word')).test(str)
// or
/word/.test(str)
str.indexOf('word') !== -1
str.includes('word')
Regular expressions seem to be faster (at least in Chrome 10).
Performance test - short haystack
Performance test - long haystack
It cannot be said with certainty which method is faster. The differences between the browsers is enormous. While in Chrome 10 indexOf
seems to be faster, in Safari 5, indexOf
is clearly slower than any other method.
You have to see and try for your self. It depends on your needs. For example a case-insensitive search is way faster with regular expressions.
Update 2018:
Just to save people from running the tests themselves, here are the current results for most common browsers, the percentages indicate performance increase over the next fastest result (which varies between browsers):
Chrome: indexOf (~98% faster) <-- wow
Firefox: cached RegExp (~18% faster)
IE11: cached RegExp(~10% faster)
Edge: indexOf (~18% faster)
Safari: cached RegExp(~0.4% faster)
Note that cached RegExp is: var r = new RegExp('simple'); var c = r.test(str);
as opposed to: /simple/.test(str)

Single elements of a tuple a
can be accessed -in an indexed array-like fashion-
via a[0]
, a[1]
, ... depending on the number of elements in the tuple.
If your tuple is a=(3,"a")
a[0]
yields 3
,a[1]
yields "a"
def tup():
return (3, "hello")
tup()
returns a 2-tuple.
In order to "solve"
i = 5 + tup() # I want to add just the three
you select the 3 by
tup()[0| #first element
so in total
i = 5 + tup()[0]
Go with namedtuple that allows you to access tuple elements by name (and by index). Details at https://docs.python.org/3/library/collections.html#collections.namedtuple
>>> import collections
>>> MyTuple=collections.namedtuple("MyTuple", "mynumber, mystring")
>>> m = MyTuple(3, "hello")
>>> m[0]
3
>>> m.mynumber
3
>>> m[1]
'hello'
>>> m.mystring
'hello'

if (chBoxListTables.Items[i].Selected)
{
string str = chBoxListTables.Items[i].Text;
MessageBox.Show(str);
var itemValue = chBoxListTables.Items[i].Value;
}
}
The "V" should be in CAPS in Value.
Here is another code example used in WinForm app and runs properly.
var chBoxList= new CheckedListBox();
chBoxList.Items.Add(new ListItem("One", "1"));
chBoxList.Items.Add(new ListItem("Two", "2"));
chBoxList.SetItemChecked(1, true);
var checkedItems = chBoxList.CheckedItems;
var chkText = ((ListItem)checkedItems[0]).Text;
var chkValue = ((ListItem)checkedItems[0]).Value;
MessageBox.Show(chkText);

getArguments()
setArguments()
methods seem very useful when it comes to instantiating a Fragment using a static method.
ieMyfragment.createInstance(String msg)
How to do it?
Fragment code
public MyFragment extends Fragment {
private String displayMsg;
private TextView text;
public static MyFragment createInstance(String displayMsg)
{
MyFragment fragment = new MyFragment();
Bundle args = new Bundle();
args.setString("KEY",displayMsg);
fragment.setArguments(args); //set
return fragment;
}
@Override
public void onCreate(Bundle bundle)
{
displayMsg = getArguments().getString("KEY"): // get
}
@Override
public View onCreateView(LayoutInlater inflater, ViewGroup parent, Bundle bundle){
View view = inflater.inflate(R.id.placeholder,parent,false);
text = (TextView)view.findViewById(R.id.myTextView);
text.setText(displayMsg) // show msg
returm view;
}
}
Let's say you want to pass a String while creating an Instance. This is how you will do it.
MyFragment.createInstance("This String will be shown in textView");
1) Why Myfragment.getInstance(String msg) is preferred over new MyFragment(String msg)?
2) Sample code on Fragments
By using the page source you will get the whole HTML code.
So first decide the block of code or tag in which you require to retrieve the data or to click the element..
options = driver.find_elements_by_name_("XXX")
for option in options:
if option.text == "XXXXXX":
print(option.text)
option.click()
You can find the elements by name, XPath, id, link and CSS path.
I'm having same problem and I tried this
Error: More than one file was found with OS independent path 'META-INF/library_release.kotlin_module'
Solution:
android {
packagingOptions {
exclude 'META-INF/library_release.kotlin_module'
}
}
$( this ).find( 'li.target' ).css("border", "3px double red");
or
$( this ).children( 'li.target' ).css("border", "3px double red");
Use children
for immediate descendants, or find
for deeper elements.
try this:
select salesid,count (salesid) from AXDelNotesNoTracking group by salesid having count (salesid) >1
You can use the Calendar
class to convert Date
public long getDifference()
{
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy");
Date d = sdf.parse("Mon May 27 11:46:15 IST 2013");
Calendar c = Calendar.getInstance();
c.setTime(d);
long time = c.getTimeInMillis();
long curr = System.currentTimeMillis();
long diff = curr - time; //Time difference in milliseconds
return diff/1000;
}
Looks like you forgot the mode parameter when calling open
, try w
:
file = open("copy.txt", "w")
file.write("Your text goes here")
file.close()
The default value is r
and will fail if the file does not exist
'r' open for reading (default)
'w' open for writing, truncating the file first
Other interesting options are
'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists
See Doc for Python2.7 or Python3.6
-- EDIT --
As stated by chepner in the comment below, it is better practice to do it with a with
statement (it guarantees that the file will be closed)
with open("copy.txt", "w") as file:
file.write("Your text goes here")
Just install
conda install graphviz
then install
conda install -c conda-forge pydotplus
I rewrote David's answer using the with
statement, it allows you do do this:
with timeout(seconds=3):
time.sleep(4)
Which will raise a TimeoutError.
The code is still using signal
and thus UNIX only:
import signal
class timeout:
def __init__(self, seconds=1, error_message='Timeout'):
self.seconds = seconds
self.error_message = error_message
def handle_timeout(self, signum, frame):
raise TimeoutError(self.error_message)
def __enter__(self):
signal.signal(signal.SIGALRM, self.handle_timeout)
signal.alarm(self.seconds)
def __exit__(self, type, value, traceback):
signal.alarm(0)
Obviously '12/01/2012 13:16:32.000' doesn't match 'DD-MON-YYYY hh24:mi' format.
Update:
You need 'MM/DD/YYYY hh24:mi:ss.ff' format and to use TO_TIMESTAMP instead of TO_DATE cause dates don't hold millis in oracle.
I had the same problem. In which i have to remove white background from jpg/png image format using ImageMagick.
What worked for me was:
1) Convert image format to png: convert input.jpg input.png
2) convert input.png -fuzz 2% -transparent white output.png
I think these are orthogonal and can be used together. Let me show you an example I recently came across at work:
We were using the Spring framework in Java for DI. A singleton class (Parent
) had to instantiate new objects of another class (Child
), and those had complex collaborators:
@Component
class Parent {
// ...
@Autowired
Parent(Dep1 dep1, Dep2 dep2, ..., DepN depN) {
this.dep1 = dep1;
this.dep2 = dep2;
}
void method(int p) {
Child c = new Child(dep1, dep2, ..., depN, p);
// ...
}
}
In this example, Parent
has to receive DepX
instances only to pass them to the Child
constructor. Problems with this:
Parent
has more knowledge of Child
than it shouldParent
has more collaborators than it shouldChild
involves changing Parent
This is when I realized a Factory
would fit here perfectly:
Child
class, as seen by Parent
Child
, which can be centralized in the DI configuration.This is the simplified Parent
class and the ChildFactory
class:
@Component
class Parent {
// ...
@Autowired
Parent(ChildFactory childFactory) {
this.childFactory = childFactory;
}
void method(int p) {
Child c = childFactory.newChild(p);
// ...
}
}
@Component
class ChildFactory {
// ...
@Autowired
Parent(Dep1 dep1, Dep2 dep2, ..., DepN depN) {
this.dep1 = dep1;
this.dep2 = dep2;
// ...
this.depN = depN;
}
Child newChild(int p) {
return new Child(dep1, dep2, ..., depN, p);
}
}
It works:
Bitmap bitmap = BitmapFactory.decodeFile(filePath);
If you want to click on all elements selected by some class, you can use this example (used on last.fm on the Loved tracks page to Unlove all).
var divs = document.querySelectorAll('.love-button.love-button--loved');
for (i = 0; i < divs.length; ++i) {
divs[i].click();
};
With ES6 and Babel (cannot be run in the browser console directly)
[...document.querySelectorAll('.love-button.love-button--loved')]
.forEach(div => { div.click(); })
I have async await working with webpack/babel build:
"devDependencies": {
"babel-preset-stage-3": "^6.11.0"
}
.babelrc:
"presets": ["es2015", "stage-3"]
Lots of ways.
Use ADO.Net and use fill on the data adapter to get a DataTable:
using (SqlDataAdapter dataAdapter
= new SqlDataAdapter ("SELECT blah FROM blahblah ", sqlConn))
{
// create the DataSet
DataSet dataSet = new DataSet();
// fill the DataSet using our DataAdapter
dataAdapter.Fill (dataSet);
}
You can then get the data table out of the dataset.
Note in the upvoted answer dataset isn't used, (It appeared after my answer) It does
// create data adapter
SqlDataAdapter da = new SqlDataAdapter(cmd);
// this will query your database and return the result to your datatable
da.Fill(dataTable);
Which is preferable to mine.
I would strongly recommend looking at entity framework though ... using datatables and datasets isn't a great idea. There is no type safety on them which means debugging can only be done at run time. With strongly typed collections (that you can get from using LINQ2SQL or entity framework) your life will be a lot easier.
Edit: Perhaps I wasn't clear: Datatables = good, datasets = evil. If you are using ADO.Net then you can use both of these technologies (EF, linq2sql, dapper, nhibernate, orm of the month) as they generally sit on top of ado.net. The advantage you get is that you can update your model far easier as your schema changes provided you have the right level of abstraction by levering code generation.
The ado.net adapter uses providers that expose the type info of the database, for instance by default it uses a sql server provider, you can also plug in - for instance - devart postgress provider and still get access to the type info which will then allow you to as above use your orm of choice (almost painlessly - there are a few quirks) - i believe Microsoft also provide an oracle provider. The ENTIRE purpose of this is to abstract away from the database implementation where possible.
Try this:
grep "string to search for" FileNameToSearch | cut -d ":" -f 4 | sort -n | uniq -c
Sample:
grep "SMTP connect from unknown" maillog | cut -d ":" -f 4 | sort -n | uniq -c
6 SMTP connect from unknown [188.190.118.90]
54 SMTP connect from unknown [62.193.131.114]
3 SMTP connect from unknown [91.222.51.253]
This worked for me:
export _JAVA_OPTIONS="-Xmx1g"
It's important that you have no spaces because for me it did not work. I would suggest just copying and pasting. Then I ran:
java -XshowSettings:vm
and it will tell you:
Picked up _JAVA_OPTIONS: -Xmx1g
Name both your submit buttons the same
<input name="submit" type="submit" id="submit" value="Save" />
<input name="submit" type="submit" id="process" value="Process" />
Then in your controller get the value of submit. Only the button clicked will pass its value.
public ActionResult Index(string submit)
{
Response.Write(submit);
return View();
}
You can of course assess that value to perform different operations with a switch block.
public ActionResult Index(string submit)
{
switch (submit)
{
case "Save":
// Do something
break;
case "Process":
// Do something
break;
default:
throw new Exception();
break;
}
return View();
}

Font Squirrel has a wonderful web font generator.
I think you should find what you need here to generate OTF fonts and the needed CSS to use them. It will even support older IE versions.
First of all, your selector is overkill. I suggest using a class or ID selector like my example below. Once you've corrected your selector, simply use jQuery's .each() to iterate through the collection:
ID Selector:
$('#mytable td').each(function() {
var cellText = $(this).html();
});
Class Selector:
$('.myTableClass td').each(function() {
var cellText = $(this).html();
});
Additional Information:
Take a look at jQuery's selector docs.
In addition to @csgillespie's answer, segments
is also vectorised to help with this sort of thing:
plot (x, y, ylim=c(0,6))
segments(x,y-sd,x,y+sd)
epsilon <- 0.02
segments(x-epsilon,y-sd,x+epsilon,y-sd)
segments(x-epsilon,y+sd,x+epsilon,y+sd)
ESCAPE CODES
Reserved Characters must be escaped by HTML: We can use a character escape to represent any Unicode character [Ex: & - U+00026] in HTML, XHTML or XML using only ASCII characters. Numeric character references [Ex: ampersand(&) - &
] & Named character references [Ex: &
] are types of character escape used in markup
.
Original Character XML entity replacement XML numeric replacement
< < <
> > >
" " "
& & &
' ' '
To display HTML Tags as a normal form in web page we use <pre>
, <code>
tags or we can escape them. Escaping the string by replacing with any occurrence of the "&"
character by the string "&"
and any occurrences of the ">"
character by the string ">"
. Ex: stackoverflow post
function escapeCharEntities() {
var map = {
"&": "&",
"<": "<",
">": ">",
"\"": """,
"'": "'"
};
return map;
}
var mapkeys = '', mapvalues = '';
var html = {
encodeRex : function () {
return new RegExp(mapkeys, 'g'); // "[&<>"']"
},
decodeRex : function () {
return new RegExp(mapvalues, 'g'); // "(&|<|>|"|')"
},
encodeMap : JSON.parse( JSON.stringify( escapeCharEntities () ) ), // json = {&: "&", <: "<", >: ">", ": """, ': "'"}
decodeMap : JSON.parse( JSON.stringify( swapJsonKeyValues( escapeCharEntities () ) ) ),
encode : function ( str ) {
var encodeRexs = html.encodeRex();
console.log('Encode Rex: ', encodeRexs); // /[&<>"']/gm
return str.replace(encodeRexs, function(m) { console.log('Encode M: ', m); return html.encodeMap[m]; }); // m = < " > SpecialChars
},
decode : function ( str ) {
var decodeRexs = html.decodeRex();
console.log('Decode Rex: ', decodeRexs); // /(&|<|>|"|')/g
return str.replace(decodeRexs, function(m) { console.log('Decode M: ', m); return html.decodeMap[m]; }); // m = < " >
}
};
function swapJsonKeyValues ( json ) {
var count = Object.keys( json ).length;
var obj = {};
var keys = '[', val = '(', keysCount = 1;
for(var key in json) {
if ( json.hasOwnProperty( key ) ) {
obj[ json[ key ] ] = key;
keys += key;
if( keysCount < count ) {
val += json[ key ]+'|';
} else {
val += json[ key ];
}
keysCount++;
}
}
keys += ']'; val += ')';
console.log( keys, ' == ', val);
mapkeys = keys;
mapvalues = val;
return obj;
}
console.log('Encode: ', html.encode('<input type="password" name="password" value=""/>') );
console.log('Decode: ', html.decode(html.encode('<input type="password" name="password" value=""/>')) );
O/P:

In java, DateFormatter by default uses DST,To avoid day Light saving (DST) you need to manually do a trick,
first you have to get the DST offset i.e. for how many millisecond DST applied, for ex somewhere DST is also for 45 minutes and for some places it is for 30 min
but in most cases DST is of 1 hour
you have to use Timezone object and check with the date whether it is falling under DST or not and then you have to manually add offset of DST into it. for eg:
TimeZone tz = TimeZone.getTimeZone("EST");
boolean isDST = tz.inDaylightTime(yourDateObj);
if(isDST){
int sec= tz.getDSTSavings()/1000;// for no. of seconds
Calendar cal= Calendar.getInstance();
cal.setTime(yourDateObj);
cal.add(Calendar.Seconds,sec);
System.out.println(cal.getTime());// your Date with DST neglected
}
Contrary to what some of the other answers have said, on most systems, in the absence of a pragma or compiler option, the size of the structure will be at least 6 bytes and, on most 32-bit systems, 8 bytes. For 64-bit systems, the size could easily be 16 bytes. Alignment does come into play; always. The sizeof a single struct has to be such that an array of those sizes can be allocated and the individual members of the array are sufficiently aligned for the processor in question. Consequently, if the size of the struct was 5 as others have hypothesized, then an array of two such structures would be 10 bytes long, and the char pointer in the second array member would be aligned on an odd byte, which would (on most processors) cause a major bottleneck in the performance.
$('#cloneDiv').click(function(){
// get the last DIV which ID starts with ^= "klon"
var $div = $('div[id^="klon"]:last');
// Read the Number from that DIV's ID (i.e: 3 from "klon3")
// And increment that number by 1
var num = parseInt( $div.prop("id").match(/\d+/g), 10 ) +1;
// Clone it and assign the new ID (i.e: from num 4 to ID "klon4")
var $klon = $div.clone().prop('id', 'klon'+num );
// Finally insert $klon wherever you want
$div.after( $klon.text('klon'+num) );
});

What is the best place is your question. The best place is inside the Controller.Initialize method. MSDN writes that it is called after the constructor and before the action method. In contrary of overriding OnActionExecuting, placing your code in the Initialize method allow you to benefit of having all custom data annotation and attribute on your classes and on your properties to be localized.
For example, my localization logic come from an class that is injected to my custom controller. I have access to this object since Initialize is called after the constructor. I can do the Thread's culture assignation and not having every error message displayed correctly.
public BaseController(IRunningContext runningContext){/*...*/}
protected override void Initialize(RequestContext requestContext)
{
base.Initialize(requestContext);
var culture = runningContext.GetCulture();
Thread.CurrentThread.CurrentUICulture = culture;
Thread.CurrentThread.CurrentCulture = culture;
}
Even if your logic is not inside a class like the example I provided, you have access to the RequestContext which allow you to have the URL and HttpContext and the RouteData which you can do basically any parsing possible.
std::vector
has a constructor that takes two iterators. You can use that:
std::string str = "hello";
std::vector<char> data(str.begin(), str.end());
If you already have a vector and want to add the characters at the end, you need a back inserter:
std::string str = "hello";
std::vector<char> data = /* ... */;
std::copy(str.begin(), str.end(), std::back_inserter(data));
Elements are added to list using append()
:
>>> data = {'list': [{'a':'1'}]}
>>> data['list'].append({'b':'2'})
>>> data
{'list': [{'a': '1'}, {'b': '2'}]}
If you want to add element to a specific place in a list (i.e. to the beginning), use insert()
instead:
>>> data['list'].insert(0, {'b':'2'})
>>> data
{'list': [{'b': '2'}, {'a': '1'}]}
After doing that, you can assemble JSON again from dictionary you modified:
>>> json.dumps(data)
'{"list": [{"b": "2"}, {"a": "1"}]}'
You could use a Common Table Expression to get the top 10 distinct ID's and then join those to the rest of your data:
;WITH TopTenIDs AS
(
SELECT DISTINCT TOP 10 id
FROM dm.labs
ORDER BY ......
)
SELECT
tti.id, pl.nm, pl.val, pl.txt_val
FROM
TopTenIDs tti
INNER JOIN
dm.labs pl ON pl.id = tti.id
INNER JOIN
mas_data.patients p ON pl.id = p.id
WHERE
pl.nm like '%LDL%'
AND val IS NOT NULL
That should work. Mind you: if you have a "TOP x" clause, you typically also need an ORDER BY clause - if you want the TOP 10, you need to tell the system in what order that "TOP" is.
PS: why do you even join the "patients" table, if you never select any fields from it??
Select menu File → New Window from the menu and then open the other folder in the new window.
If you are using Bootstrap at the same time, you can use:
<i class="fa fa-check-circle-o fa-5x text-success" ></i>
Otherwise:
<i class="fa fa-check-circle-o fa-5x" style="color:green"></i>
Use PowerShell:
$Server = "TestServer"
$Database = "TestDatabase"
$Query = "select * from TestTable"
$FilePath = "C:\OutputFile.csv"
# This will overwrite the file if it already exists.
Invoke-Sqlcmd -Query $Query -Database $Database -ServerInstance $Server | Export-Csv $FilePath
In my usual cases, all I really need is a CSV file that can be read by Excel. However, if you need an actual Excel file, then tack on some code to convert the CSV file to an Excel file. This answer gives a solution for this, but I've not tested it.
I'm not sure what kind of scheduled tasks you mean. If you mean stuff like "every hour, refresh foo.xml" type tasks, then use the Windows Scheduled Tasks system. (The "at" command, or via the controller.) Have it either run a console app or request a special page that kicks off the process.
Edit: I should add, this is an OK way to get your IIS app running at scheduled points too. So suppose you want to check your DB every 30 minutes and email reminders to users about some data, you can use scheduled tasks to request this page and hence get IIS processing things.
If your needs are more complex, you might consider creating a Windows Service and having it run a loop to do whatever processing you need. This also has the benefit of separating out the code for scaling or management purposes. On the downside, you need to deal with Windows services.
Example to download with wget on server a big file link that can be obtained in your browser.
In example using Google Chrome.
Login where you need, and press download. Go to download and copy your link.
Then open DevTools on a page where you where login, go to Console and get your cookies, by entering document.cookie
Now, go to server and download your file: wget --header "Cookie: <YOUR_COOKIE_OUTPUT_FROM_CONSOLE>" <YOUR_DOWNLOAD_LINK>
The ways in which you can get the results are:
Which is better is dependent on 3 things:
Read More: http://paltman.com/try-except-performance-in-python-a-simple-test/
Use of try/block instead of 'in' or 'if':
try:

except KeyError:
# Do the operation you wanted to do for "key not present in dict".
else:
# Do the operation you wanted to do with "key present in dict."
None of the answers solved exactly my problem (the solution file I was running was trying to find xcopy to copy a dll after generation).
What solved it for me was going into menu "Project -> Properties"
Then in the window that opens choosing on the left pane: "Configuration Properties -> VC++ Directories
On the right pane under "General" choosing "Executable Directories "
And then adding:
$(SystemRoot)\system32;$(SystemRoot);$(SystemRoot)\System32\Wbem;$(SystemRoot)\System32\WindowsPowerShell\v1.0\;$(ExecutablePath)
Although this have an accepted answer I would like to add an observation:
In ES6 using let
doesn't work:
/*this is NOT working*/_x000D_
let t = "skyBlue",_x000D_
m = "gold",_x000D_
b = "tomato";_x000D_
_x000D_
let color = window["b"];_x000D_
console.log(color);
_x000D_
However using var
works
/*this IS working*/_x000D_
var t = "skyBlue",_x000D_
m = "gold",_x000D_
b = "tomato";_x000D_
_x000D_
let color = window["b"];_x000D_
console.log(color);
_x000D_
I hope this may be useful to some.
Also, please make sure you installed the correct version of apache on your computer. For example, not install a x86 on a 64bit system. Vice versa.
if you don't want to use float
<div style="text-align:right; margin:0px auto 0px auto;">

I really suggest you to use the Glide library. It's among the most efficient way to generate and display a video thumbnail for a local video file.
Just add this line to your gradle file :
compile 'com.github.bumptech.glide:glide:3.7.0'
And it will become as simple as :
String filePath = "/storage/emulated/0/Pictures/example_video.mp4";
Glide
.with( context )
.load( Uri.fromFile( new File( filePath ) ) )
.into( imageViewGifAsBitmap );
You can find more informations here : https://futurestud.io/blog/glide-displaying-gifs-and-videos

Before Netscape invented cookies and HTTPS in 1994 http could be considered stateless. As time progressed more and more stateful aspects were added for a myriad of reasons, including performance and security.
While HTTP 1 originally sought out to be stateless many HTTP/2 components are the very definition of stateful. HTTP/2 abandoned stateless goals.
No reasonable person can read the HTTP/2 RFC and think it is stateless. The errant "HTTP is stateless" old time dogma is false and far from the current reality of stateful HTTP.
Here's a limited, and not exhaustive list, of stateful HTTP/1 and HTTP/2 components:
Section 5.1 of the HTTP/2 RFC is a great example of stateful mechanisms defined by the HTTP/2 standard.
Is it safe for web applications to consider HTTP/2 as a stateless protocol?
HTTP/2 is a stateful protocol, but that doesn't mean your HTTP/2 application can't be stateless. You can choose to not use certain stateful features for stateless HTTP/2 applications by using only a subset of HTTP/2 features.
Cookies and some other stateful mechanisms, or less obvious stateful mechanisms, are later HTTP additions. HTTP 1 is said to be stateless although in practice we use standardized stateful mechanisms, like cookies, TLS, and caching. Unlike HTTP/1, HTTP/2 defines stateful components in its standard from the very beginning. A particular HTTP/2 application can use a subset of HTTP/2 features to maintain statelessness, but the protocol itself anticipate state to be the norm, not the exception.
Existing applications, even HTTP 1 applications, needing state will break if trying to use them statelessly. It can be impossible to log into some HTTP/1.1 websites if cookies are disabled, thus breaking the application. It may not be safe to assume that a particular HTTP 1 application does not use state. This is no different for HTTP/2.
Say it with me one last time:
HTTP/2 is a stateful protocol.
We can use data.table to get it quickly. First create df without factors,
df <- data.frame(list(A=c("","xyz","jkl"), B=c(12,"",100)), stringsAsFactors=F)
Now you can use
setDT(df)
for (jj in 1:ncol(df)) set(df, i = which(df[[jj]]==""), j = jj, v = NA)
and you can convert it back to a data.frame
setDF(df)
If you only want to use data.frame and keep factors it's more difficult, you need to work with
levels(df$value)[levels(df$value)==""] <- NA
where value is the name of every column. You need to insert it in a loop.
This solution might also appeal to you, depending on how your mind works:
from pathlib import Path
def get_size(path = Path('.')):
""" Gets file size, or total directory size """
if path.is_file():
size = path.stat().st_size
elif path.is_dir():
size = sum(file.stat().st_size for file in path.glob('*.*'))
return size
def format_size(path, unit="MB"):
""" Converts integers to common size units used in computing """
bit_shift = {"B": 0,
"kb": 7,
"KB": 10,
"mb": 17,
"MB": 20,
"gb": 27,
"GB": 30,
"TB": 40,}
return "{:,.0f}".format(get_size(path) / float(1 << bit_shift[unit])) + " " + unit
# Tests and test results
>>> get_size("d:\\media\\bags of fun.avi")
'38 MB'
>>> get_size("d:\\media\\bags of fun.avi","KB")
'38,763 KB'
>>> get_size("d:\\media\\bags of fun.avi","kb")
'310,104 kb'
You can use android's inbuilt Patterns
:
public boolean validCellPhone(String number)
{
return android.util.Patterns.PHONE.matcher(number).matches();
}
This pattern is intended for searching for things that look like they might be phone numbers in arbitrary text, not for validating whether something is in fact a phone number. It will miss many things that are legitimate phone numbers.
The pattern matches the following:
- Optionally, a + sign followed immediately by one or more digits. Spaces, dots, or dashes may follow.
- Optionally, sets of digits in parentheses, separated by spaces, dots, or dashes.
- A string starting and ending with a digit, containing digits, spaces, dots, and/or dashes.
Another thing you might want to enforce is making sure your abstract class is not instantiated. You can do that by defining a function that acts as FLAG ones set as the Abstract class constructor. This will then try to construct the FLAG which will call its constructor containing exception to be thrown. Example below:
(function(){
var FLAG_ABSTRACT = function(__class){
throw "Error: Trying to instantiate an abstract class:"+__class
}
var Class = function (){
Class.prototype.constructor = new FLAG_ABSTRACT("Class");
}
//will throw exception
var foo = new Class();
})()
This script detects all versions of Firefox, for Desktop, from version 1 to 46.
It's the third time I've tried to answer this question on StackOverflow because I kept finding new ways to break my script. However, I think it's working now. It's a great exercise to learn about Firefox features and interesting to see how things have evolved. The script can be rewritten with different features, I chose ones I thought would be most useful, I would love for someone else to rewrite with other more useful features and post here, and compare results.
I placed the script in a try statement in case the user has any disabled settings in about.config. Otherwise I tested on every version of Firefox and it detects each one. I gave a brief description of what each feature is used for in the comments. I would like to do this for Webkit too but find the documentation not as good. Mozilla has easy to download previous versions and detailed releases.

I am adding this new answer because as per JDK8 documentation jcmd is suggested approach now.
It is suggested to use the latest utility, jcmd instead of the previous jstack, jinfo, and jmap utilities for enhanced diagnostics and reduced performance overhead.
Below are commands to get your properties/flags you want.
jcmd pid VM.system_properties
jcmd pid VM.flags
We need pid, for this use jcmd -l, like below
username@users-Air:~/javacode$ jcmd -l
11441 Test
6294 Test
29197 jdk.jcmd/sun.tools.jcmd.JCmd -l
Now time to use these pids to get properties/flags you want
Command: jcmd 11441 VM.system_properties

condition ? value if true : value if false
A modern and fast solution, for Python 3.7. May also work in some interpreters of Python 3.6.
TLDR
To sort a dictionary by keys use:
sorted_dict = {k: disordered[k] for k in sorted(disordered)}
Almost three times faster than the accepted answer; probably more when you include imports.
Comment on the accepted answer
The example in the accepted answer instead of iterating over the keys only - with key
parameter of sorted()
or the default behaviour of dict iteration - iterates over tuples (key, value)
, which suprisingly turns out to be much slower than comparing the keys only and accessing dictionary elements in a list comprehension.
How to sort by key in Python 3.7
The big change in Python 3.7 is that the dictionaries are now ordered by default.
OrderedDict
might still be preferable for the compatibility sake.sorted(d.items())
without key
.See:
disordered = {10: 'b', 3: 'a', 5: 'c'}
# sort keys, then get values from original - fast
sorted_dict = {k: disordered[k] for k in sorted(disordered)}
# key = itemgetter - slower
from operator import itemgetter
key = itemgetter(0)
sorted_dict = {k: v for k, v in sorted(disordered.items(), key=key)}
# key = lambda - the slowest
key = lambda item: item[0]
sorted_dict = {k: v for k in sorted(disordered.items(), key=key)}
Timing results:
Best for {k: d[k] for k in sorted(d)}: 7.507327548999456
Best for {k: v for k, v in sorted(d.items(), key=key_getter)}: 12.031082626002899
Best for {k: v for k, v in sorted(d.items(), key=key_lambda)}: 14.22885995300021
Best for dict(sorted(d.items(), key=key_getter)): 11.209122000000207
Best for dict(sorted(d.items(), key=key_lambda)): 13.289728325995384
Best for dict(sorted(d.items())): 14.231471302999125
Best for OrderedDict(sorted(d.items(), key=key_getter)): 16.609151654003654
Best for OrderedDict(sorted(d.items(), key=key_lambda)): 18.52622927199991
Best for OrderedDict(sorted(d.items())): 19.436101284998585
Testing code:
from timeit import repeat
setup_code = """
from operator import itemgetter
from collections import OrderedDict
import random
random.seed(0)
d = {i: chr(i) for i in [random.randint(0, 120) for repeat in range(120)]}
key_getter = itemgetter(0)
key_lambda = lambda item: item[0]
"""
cases = [
# fast
'{k: d[k] for k in sorted(d)}',
'{k: v for k, v in sorted(d.items(), key=key_getter)}',

I've been playing around with the preferences and added the following to my brackets.json
file (access in Menu Bar: Debug: "Open Preferences File").
"closeTags": {
"dontCloseTags": ["br", "hr", "img", "input", "link", "meta", "area", "base", "col", "command", "embed", "keygen", "param", "source", "track", "wbr"],
"indentTags": ["ul", "ol", "div", "section", "table", "tr"],
}
dontCloseTags
are tags such as <br>
which shouldn't be closed.indentTags
are tags that you want to automatically create a new
indented line - add more as needed!It is a pointer to a pointer, so yes, in a way it's a 2D character array. In the same way that a char*
could indicate an array of char
s, a char**
could indicate that it points to and array of char*
s.
Try this piece of code to create circular progress bar(pie chart). pass it integer value to draw how many percent of filling area. :)
private void circularImageBar(ImageView iv2, int i) {
Bitmap b = Bitmap.createBitmap(300, 300,Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(b);
Paint paint = new Paint();
paint.setColor(Color.parseColor("#c4c4c4"));
paint.setStrokeWidth(10);
paint.setAntiAlias(true);
paint.setStyle(Paint.Style.STROKE);
canvas.drawCircle(150, 150, 140, paint);
paint.setColor(Color.parseColor("#FFDB4C"));
paint.setStrokeWidth(10);
paint.setStyle(Paint.Style.FILL);
final RectF oval = new RectF();
paint.setStyle(Paint.Style.STROKE);
oval.set(10,10,290,290);
canvas.drawArc(oval, 270, ((i*360)/100), false, paint);
paint.setStrokeWidth(0);
paint.setTextAlign(Align.CENTER);
paint.setColor(Color.parseColor("#8E8E93"));
paint.setTextSize(140);
canvas.drawText(""+i, 150, 150+(paint.getTextSize()/3), paint);
iv2.setImageBitmap(b);

If you have iAds in your binary you will not be able to run it on anything before iOS 4.0 and it will be rejected if you try and submit a binary like this.
You can still run the simulator from 3.2 onwards after upgrading.
In the iPhone Simulator try selecting Hardware -> Version -> 3.2
I'd be careful about trying to get too clever here. I think it's confusing as it is and using more advanced nth-child
parameters will only make it more complicated. As for the background color I'd just set that to a variable.
Here goes what I came up with before I realized trying to be too clever might be a bad thing.
#romtest {
$bg: #e5e5e5;
.detailed {
th {
&:nth-child(-2n+6) {
background-color: $bg;
}
}
td {
&:nth-child(3n), &:nth-child(2), &:nth-child(7) {
background-color: $bg;
}
&.last {
&:nth-child(-2n+4){
background-color: $bg;
}
}
}
}
}
and here is a quick demo: http://codepen.io/anon/pen/BEImD
----EDIT----
Here's another approach to avoid retyping background-color
:
#romtest {
%highlight {
background-color: #e5e5e5;
}
.detailed {
th {
&:nth-child(-2n+6) {
@extend %highlight;
}
}
td {
&:nth-child(3n), &:nth-child(2), &:nth-child(7) {
@extend %highlight;
}
&.last {
&:nth-child(-2n+4){
@extend %highlight;
}
}
}
}

echo "*" > /path/to/bin/Debug/.gitignore
echo "*" > /path/to/bin/Release/.gitignore
If you've made previous commits, remember to remove previously tracked files:
git rm -rf /path/to/bin/Debug
git rm -rf /path/to/bin/Release
You can confirm it by doing git status
to show you all the files removed from tracking.
If you already have nodejs installed (check with which nodejs
) and don't want to install another package, you can, as root:
update-alternatives --install /usr/bin/node node /usr/bin/nodejs 99
You can do something like this:
T1 = (('13', '17', '18', '21', '32'),
('07', '11', '13', '14', '28'),
('01', '05', '06', '08', '15', '16'))
new_list = list(list(int(a) for a in b if a.isdigit()) for b in T1)
print(new_list)
Me too on a different scenario.
<ComboBox Cursor="Hand" DataContext="{Binding}"
FontSize="16" Height="27" ItemsSource="{Binding}"
Name="cbxDamnCombo" SelectedIndex="0" SelectedValuePath="MemberId">
<DataTemplate>
<TextBlock DataContext="{Binding}">
<TextBlock.Text>
<MultiBinding StringFormat="{}{0} / {1}">
<Binding Path="MemberName"/>
<Binding Path="Phone"/>
</MultiBinding>
</TextBlock.Text>
</TextBlock>
</DataTemplate>
</ComboBox>
Now when you complete with the missing tag Control.ItemTemplate, everything gets to normal:
<ComboBox Cursor="Hand" DataContext="{Binding}"
FontSize="16" Height="27" ItemsSource="{Binding}"
Name="cbxDamnCombo" SelectedIndex="0" SelectedValuePath="MemberId">
<ComboBox.ItemTemplate>
<DataTemplate>
<TextBlock DataContext="{Binding}">
<TextBlock.Text>
<MultiBinding StringFormat="{}{0} / {1}">
<Binding Path="MemberName"/>
<Binding Path="Phone"/>
</MultiBinding>
</TextBlock.Text>
</TextBlock>
</DataTemplate>
<ComboBox.ItemTemplate>
</ComboBox>
In my case (NOT using expo & Android build)
package.json
"dependencies": {
"react": "16.3.1",
"react-native": "0.55.2"
}
And app.json
{
"sdkVersion": "27"
}
resolved the issue
event.stopPropagation() allows other handlers on the same element to be executed, while event.stopImmediatePropagation() prevents every event from running. For example, see below jQuery code block.
$("p").click(function(event)
{ event.stopImmediatePropagation();
});
$("p").click(function(event)
{ // This function won't be executed
$(this).css("color", "#fff7e3");
});
If event.stopPropagation was used in previous example, then the next click event on p element which changes the css will fire, but in case event.stopImmediatePropagation(), the next p click event will not fire.
Default constructors -- public constructors with out arguments (either declared or implied) -- are inherited by default. You can try the following code for an example of this:
public class CtorTest {
public static void main(String[] args) {
final Sub sub = new Sub();
System.err.println("Finished.");
}
private static class Base {
public Base() {
System.err.println("In Base ctor");
}
}
private static class Sub extends Base {
public Sub() {
System.err.println("In Sub ctor");
}
}
}
If you want to explicitly call a constructor from a super class, you need to do something like this:
public class Ctor2Test {
public static void main(String[] args) {
final Sub sub = new Sub();
System.err.println("Finished.");
}
private static class Base {
public Base() {
System.err.println("In Base ctor");
}
public Base(final String toPrint) {
System.err.println("In Base ctor. To Print: " + toPrint);
}
}
private static class Sub extends Base {
public Sub() {
super("Hello World!");
System.err.println("In Sub ctor");
}
}
}
The only caveat is that the super() call must come as the first line of your constructor, else the compiler will get mad at you.
I know that lots of other people have found solutions that worked for their particular case, but since none of them worked for my particular case, I thought this might be helpful to someone else.
Some details:
I'm using google maps API v3 on a project where inline CSS is something we really, really want to avoid. My infowindows were working for everything except for IE11, where the width was not calculated correctly. This resulted in div overflows, which triggered scrollbars.
I had to do three things:
Remove all display: inline-block style rules from anything inside of the infowindow content (I replaced with display: block) - I got the idea to try this from a thread (which I can't find anymore) where someone was having the same problem with IE6.
Pass the content as a DOM node instead of as a string. I am using jQuery, so I could do this by replacing: infowindow.setContent(infoWindowDiv.html());
with infowindow.setContent($(infoWindowDiv.html())[0]);
This turned out to be easiest for me, but there are lots of other ways to get the same result.
Use the "setMaxWidth" hack - set the MaxWidth option in the constructor - setting the option later doesn't work. If you don't really want a max width, just set it to a very large number.
I don't know why these worked, and I'm not sure if a subset of them would work. I know that none of them work for all of my use cases individually, and that 2 + 3 doesn't work. I didn't have time to test 1 + 2 or 1 + 3.
