This is what I have done in order to get the column "first_name" fill the space when all the columns cannot do it.
When the grid go to small the column "first_name" gets almost invisible (very thin) so I can set the DataGridViewAutoSizeColumnMode to AllCells as the others visible columns. For performance issues it´s important to set them to None before data binding it and set back to AllCell in the DataBindingComplete event handler of the grid. Hope it helps!
private void dataGridView1_Resize(object sender, EventArgs e)
{
int ColumnsWidth = 0;
foreach(DataGridViewColumn col in dataGridView1.Columns)
{
if (col.Visible) ColumnsWidth += col.Width;
}
if (ColumnsWidth <dataGridView1.Width)
{
dataGridView1.Columns["first_name"].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
}
else if (dataGridView1.Columns["first_name"].Width < 10) dataGridView1.Columns["first_name"].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
}
In Python 3, print is a function, you need to call it like print("hello world").
I like to used this method the most, it will auto select the first column to the last column being used. However, if the last cell in the first row or the last cell in the first column are empty, this code will not calculate properly. Check the link for other methods to dynamically select cell range.
Sub DynamicRange()
'Best used when first column has value on last row and first row has a value in the last column
Dim sht As Worksheet
Dim LastRow As Long
Dim LastColumn As Long
Dim StartCell As Range
Set sht = Worksheets("Sheet1")
Set StartCell = Range("A1")
'Find Last Row and Column
LastRow = sht.Cells(sht.Rows.Count, StartCell.Column).End(xlUp).Row
LastColumn = sht.Cells(StartCell.Row, sht.Columns.Count).End(xlToLeft).Column
'Select Range
sht.Range(StartCell, sht.Cells(LastRow, LastColumn)).Select
End Sub
I am heavily tempted to close this as a duplicate; this question appears to be answered in many different ways all over the site:
As it seems impossible to filter the XPath message data (it isn't in the XML to filter), you can also use powershell to search:
Get-WinEvent -LogName System | Where-Object {$_.Message -like "*recycle*"}
From this, I can see that the event Id for recycling seems to be 5074, so you can filter on this as well. I hope this helps someone as this information seemed to take a lot longer than expected to work out.
This along with @BlackHawkDesign comment should help you find what you need.
I had the same issue. Maybe interesting to mention is that you have to configure in which cases the app pool recycle event is logged. By default it's in a couple of cases, not all of them. You can do that in IIS > app pools > select the app pool > advanced settings > expand generate recycle event log entry – BlackHawkDesign Jan 14 '15 at 10:00
This is the easiest way I found:
exec-Sync: https://github.com/jeremyfa/node-exec-sync
(Not to be confused with execSync.)
Execute shell command synchronously. Use this for migration scripts, cli programs, but not for regular server code.Example:
var execSync = require('exec-sync');
var user = execSync('echo $USER');
console.log(user);
cpdf will do the job from the command-line. It isn't python, though (afaik):
cpdf -add-text "Line of text" input.pdf -o output .pdf
Seq is a trait that List implements.
If you define your container as Seq, you can use any container that implements Seq trait.
scala> def sumUp(s: Seq[Int]): Int = { s.sum }
sumUp: (s: Seq[Int])Int
scala> sumUp(List(1,2,3))
res41: Int = 6
scala> sumUp(Vector(1,2,3))
res42: Int = 6
scala> sumUp(Seq(1,2,3))
res44: Int = 6
Note that
scala> val a = Seq(1,2,3)
a: Seq[Int] = List(1, 2, 3)
Is just a short hand for:
scala> val a: Seq[Int] = List(1,2,3)
a: Seq[Int] = List(1, 2, 3)
if the container type is not specified, the underlying data structure defaults to List.
Here are the simple steps to create a GitHub Tag, when you release build from master.
Open source_tree tab
Right click on Tag sections from Tag which appear on left navigation section
Click on New Tag()
Click on Add Tag from give name to tag (preferred version name of the code)
If you want to push the TAG on remote, while creating the TAG ref: step 5 which gives checkbox push TAG to origin check it and pushed tag appears on remote repository
In case while creating the TAG if you have forgotten to check the box Push to origin, you can do it later by right-clicking on the created TAG, click on Push to origin.
This worked for me when I got the same error message...
mvn install deploy
$("#citiesList").change(function() {
alert($("#citiesList option:selected").text());
alert($("#citiesList option:selected").val());
});
citiesList is id of select tag
Looks like no, though it was requested, and there’s a UDF for it.
Edit: Or there’s… this. Ugh.
If you want to clean up the whole form, you can use such approach. This is your model into controller:
$scope.registrationForm = {
'firstName' : '',
'lastName' : ''
};
Your HTML:
<form class="form-horizontal" name="registrForm" role="form">
<input type="text" class="form-control"
name="firstName"
id="firstName"
ng-model="registrationForm.firstName"
placeholder="First name"
required> First name
<input type="text" class="form-control"
name="lastName"
id="lastName"
ng-model="registrationForm.lastName"
placeholder="Last name"
required> Last name
</form>
Then, you should clone/save your clear state by:
$scope.originForm = angular.copy($scope.registrationForm);
Your reset function will be:
$scope.resetForm = function(){
$scope.registrationForm = angular.copy($scope.originForm); // Assign clear state to modified form
$scope.registrForm.$setPristine(); // this line will update status of your form, but will not clean your data, where `registrForm` - name of form.
};
In such way you are able to clean up the whole your form
For a view you can set opacity by the following.
view_name.setAlpha(float_value);
The property view.setAlpha(int) is deprecated for the API version greater than 11. Henceforth, property like .setAlpha(0.5f) is used.
I suggested you the easiest way to implement Parcelable if you are using Android Studio.
Simply go to File->Settings->Plugins->Browse Repository and search for parcelable .See image
It will automatically create Parcelable.
And there is a webiste also for doing this. http://www.parcelabler.com/
Use a SQL DATA READER:
In this example i use a List instead an array.
try
{
SqlCommand comm = new SqlCommand("SELECT CategoryID, CategoryName FROM Categories;",connection);
connection.Open();
SqlDataReader reader = comm.ExecuteReader();
List<string> str = new List<string>();
int i=0;
while (reader.Read())
{
str.Add( reader.GetValue(i).ToString() );
i++;
}
reader.Close();
}
catch (Exception)
{
throw;
}
finally
{
connection.Close();
}
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
window.location.href = marker.url;
}
})(marker, i));
There are three streaming protocols / technology in HTML5:
Live streaming, low latency - WebRTC - Websocket
VOD and Live streaming, high latency - HLS
1. WebRTC
In fact WebRTC is SRTP(secure RTP protocol). Thus we can say that video tag supports RTP(SRTP) indirectly via WebRTC.
Therefore to get RTP stream on your Chrome, Firefox or another HTML5 browser, you need a WebRTC server which will deliver the SRTP stream to browser.
2. Websocket
It is TCP based, but with lower latency than HLS. Again you need a Websocket server.
3. HLS
Most popular high-latency streaming protocol for VOD(pre-recorded video).
This is caused because all the changes to the RemoteViews are serialised (e.g. setInt and setImageViewBitmap ). The bitmaps are also serialised into an internal bundle. Unfortunately this bundle has a very small size limit.
You can solve it by scaling down the image size this way:
public static Bitmap scaleDownBitmap(Bitmap photo, int newHeight, Context context) {
final float densityMultiplier = context.getResources().getDisplayMetrics().density;
int h= (int) (newHeight*densityMultiplier);
int w= (int) (h * photo.getWidth()/((double) photo.getHeight()));
photo=Bitmap.createScaledBitmap(photo, w, h, true);
return photo;
}
Choose newHeight to be small enough (~100 for every square it should take on the screen) and use it for your widget, and your problem will be solved :)
Are you searching for this:
int c = some_ascii_character;
Or just converting without assignment:
(int)some_aschii_character;
In addition to @JBNizet's answer, my general use case for ifPresent is to combine .isPresent() and .get():
Old way:
Optional opt = getIntOptional();
if(opt.isPresent()) {
Integer value = opt.get();
// do something with value
}
New way:
Optional opt = getIntOptional();
opt.ifPresent(value -> {
// do something with value
})
This, to me, is more intuitive.
See ?substring.
x <- 'hello stackoverflow'
substring(x, 1, 1)
## [1] "h"
substring(x, 2)
## [1] "ello stackoverflow"
The idea of having a pop method that both returns a value and has a side effect of updating the data stored in x is very much a concept from object-oriented programming. So rather than defining a pop function to operate on character vectors, we can make a reference class with a pop method.
PopStringFactory <- setRefClass(
"PopString",
fields = list(
x = "character"
),
methods = list(
initialize = function(x)
{
x <<- x
},
pop = function(n = 1)
{
if(nchar(x) == 0)
{
warning("Nothing to pop.")
return("")
}
first <- substring(x, 1, n)
x <<- substring(x, n + 1)
first
}
)
)
x <- PopStringFactory$new("hello stackoverflow")
x
## Reference class object of class "PopString"
## Field "x":
## [1] "hello stackoverflow"
replicate(nchar(x$x), x$pop())
## [1] "h" "e" "l" "l" "o" " " "s" "t" "a" "c" "k" "o" "v" "e" "r" "f" "l" "o" "w"
I had the same issue in trying to start the server and followed the "checked" solution. But still had the problem. The issue was the my /etc/my.cnf file was not pointing to my designated datadir as defined when I executed the mysql_install_db with --datadir defined. Once I updated this, the server started correctly.
To clarify:
Strongly Connected Components will find all subgraphs that have at least one cycle in them, not all possible cycles in the graph. e.g. if you take all strongly connected components and collapse/group/merge each one of them into one node (i.e. a node per component), you'll get a tree with no cycles (a DAG actually). Each component (which is basically a subgraph with at least one cycle in it) can contain many more possible cycles internally, so SCC will NOT find all possible cycles, it will find all possible groups that have at least one cycle, and if you group them, then the graph will not have cycles.
to find all simple cycles in a graph, as others mentioned, Johnson's algorithm is a candidate.
To find all files modified in the last 24 hours use the one below. The -1 here means changed 1 day or less ago.
find . -mtime -1 -ls
Just use the * before it:
set<unsigned long>::iterator it;
for (it = myset.begin(); it != myset.end(); ++it) {
cout << *it;
}
This dereferences it and allows you to access the element the iterator is currently on.
I stumbled over this thread searching for answer to similar case. Basically all answers are found, but it's still hard to extract the essentials from them.

If you are expecting double, decimal, float, integer why not use the one which accomodates all namely decimal (128 bits are enough for most numbers you are looking at).
instead of (double)value use decimal.Parse(value.ToString()) or Convert.ToDecimal(value)
The biggest benefit of lambda expressions and anonymous functions is the fact that they allow the client (programmer) of a library/framework to inject functionality by means of code in the given library/framework ( as it is the LINQ, ASP.NET Core and many others ) in a way that the regular methods cannot. However, their strength is not obvious for a single application programmer but to the one that creates libraries that will be later used by others who will want to configure the behaviour of the library code or the one that uses libraries. So the context of effectively using a lambda expression is the usage/creation of a library/framework.
Also since they describe one-time usage code they don't have to be members of a class where that will led to more code complexity. Imagine to have to declare a class with unclear focus every time we wanted to configure the operation of a class object.
Try SELECT CAST(field1 AS DECIMAL(10,2)) field1 and replace 10,2 with whatever precision you need.
As you stated, package names are usually in the form of 'com.organizationName.appName' - all lowercase and no spaces. It sounds like the package name that you entered when uploading the app was different from the one declared in the AndroidManifest.
f=open(file,"r")
lines=f.readlines()
result=[]
for x in lines:
result.append(x.split(' ')[1])
f.close()
You can do the same using a list comprehension
print([x.split(' ')[1] for x in open(file).readlines()])
Docs on split()
string.split(s[, sep[, maxsplit]])Return a list of the words of the string
s. If the optional second argument sep is absent or None, the words are separated by arbitrary strings of whitespace characters (space, tab, newline, return, formfeed). If the second argument sep is present and not None, it specifies a string to be used as the word separator. The returned list will then have one more item than the number of non-overlapping occurrences of the separator in the string.
So, you can omit the space I used and do just x.split() but this will also remove tabs and newlines, be aware of that.
Looks like you use %p: Print Pointers

Personally this post helped me to solve this issue by moving the google() to the top of the repositories.
When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.
With Basic Auth, the HTTP request from the question will look something like this:
GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk
The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).
To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.
When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.
Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.
When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.
Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.
See some of the answers to my similar question why-cant-i-push-from-a-shallow-clone and the link to the recent thread on the git list.
Ultimately, the 'depth' measurement isn't consistent between repos, because they measure from their individual HEADs, rather than (a) your Head, or (b) the commit(s) you cloned/fetched, or (c) something else you had in mind.
The hard bit is getting one's Use Case right (i.e. self-consistent), so that distributed, and therefore probably divergent repos will still work happily together.
It does look like the checkout --orphan is the right 'set-up' stage, but still lacks clean (i.e. a simple understandable one line command) guidance on the "clone" step. Rather it looks like you have to init a repo, set up a remote tracking branch (you do want the one branch only?), and then fetch that single branch, which feels long winded with more opportunity for mistakes.
Edit: For the 'clone' step see this answer
If you just want the button to have different styling while the mouse is pressed you can use the :active pseudo class.
.button:active {
}
If on the other hand you want the style to stay after clicking you will have to use javascript.
Try this $('div').myFunction();
This should work
$(document).ready(function() {
$('#btnSun').click(function(){
myFunction();
});
function myFunction()
{
alert('hi');
}
Edit: note that this answer is 3+ years old. For newer versions of apache, please see the answer by sp00n. Leaving this answer for users of older versions of apache.
For debugging mod_rewrite issues, you'll want to use RewriteLogLevel and RewriteLog:
RewriteLogLevel 3
RewriteLog "/usr/local/var/apache/logs/rewrite.log"
Call parent.remove(panel), where parent is the container that you want the frame in and panel is the panel you want to add.
I think you just need to add 2 more options (contentType and dataType):
$('#my_get_related_keywords').click(function() {
$.ajax({
type: "POST",
url: "HERE PUT THE PATH OF YOUR SERVICE OR PAGE",
data: '{"HERE YOU CAN PUT DATA TO PASS AT THE SERVICE"}',
contentType: "application/json; charset=utf-8", // this
dataType: "json", // and this
success: function (msg) {
//do something
},
error: function (errormessage) {
//do something else
}
});
}
I wrote a method that handles the following edge-cases:
", ".join({'abc'}) will return "a, b, c". My desired output was "abc".""def set_to_str(set_to_convert, separator=", "):
set_size = len(set_to_convert)
if not set_size:
return ""
elif set_size == 1:
(element,) = set_to_convert
return str(element)
else:
return separator.join(map(str, set_to_convert))
I encountered the same issue with CSS on a live environment. I followed all of the advise here and investigated how the bundling works behind the scene. This lead me to request that the .Net cache was cleared (I didn't have access to the app servers) which caused the bundling to start working on the app servers. However, when accessing the site via a load balancer with a CDN configured, although the bundle identifier was updated in the url, the bundle contained the old CSS. Simply flushing the CDN resolved the issue.
I hope this goes some way to helping some one else who may encounter this
EDIT Since not so recently by now, MinGW-w64 has "absorbed" one of the toolchain building projects. The downloads can be found here. The installer should work, and allow you to pick a version that you need.
Note the Qt SDK comes with the same toolchain. So if you are developing in Qt and using the SDK, just use the toolchain it comes with.
Another alternative that has up to date toolchains comes from... harhar... a Microsoft developer, none other than STL (Stephan T. Lavavej, isn't that a spot-on name for the maintainer of MSVC++ Standard Library!). You can find it here. It includes Boost.
Another option which is highly useful if you care for prebuilt dependencies is MSYS2, which provides a Unix shell (a Cygwin fork modified to work better with Windows pathnames and such), also provides a GCC. It usually lags a bit behind, but that is compensated for by its good package management system and stability. They also provide a functional Clang with libc++ if you care for such thing.
I leave the below for reference, but I strongly suggest against using MinGW.org, due to limitations detailed below. TDM-GCC (the MinGW-w64 version) provides some hacks that you may find useful in your specific situation, although I recommend using vanilla GCC at all times for maximum compatibility.
GCC for Windows is provided by two projects currently. They both provide a very own implementation of the Windows SDK (headers and libraries) which is necessary because GCC does not work with Visual Studio files.
The older mingw.org, which @Mat already pointed you to. They provide only a 32-bit compiler. See here for the downloads you need:
Alternatively, download mingw-get and use that.
The newer mingw-w64, which as the name predicts, also provides a 64-bit variant, and in the future hopefully some ARM support. I use it and built toolchains with their CRT. Personal and auto builds are found under "Toolchains targetting Win32/64" here. They also provide Linux to Windows cross-compilers. I suggest you try a personal build first, they are more complete. Try mine (rubenvb) for GCC 4.6 to 4.8, or use sezero's for GCC 4.4 and 4.5. Both of us provide 32-bit and 64-bit native toolchains. These packages include everything listed above. I currently recommend the "MinGW-Builds" builds, as these are currently sanctioned as "official builds", and come with an installer (see above).
For support, send an email to [email protected] or post on the forum via sourceforge.net.
Both projects have their files listed on sourceforge, and all you have to do is either run the installer (in case of mingw.org) or download a suitable zipped package and extract it (in the case of mingw-w64).
There are a lot of "non-official" toolchain builders, one of the most popular is TDM-GCC. They may use patches that break binary compatibility with official/unpatched toolchains, so be careful using them. It's best to use the official releases.
After jQuery 1.7 the preferred methods are .on() and .off()
Sean's answer shows an example.
Use the jQuery functions
.live()and.die(). Available in jQuery 1.3.xFrom the docs:
To display each paragraph's text in an alert box whenever it is clicked:
$("p").live("click", function(){ alert( $(this).text() ); });Also, the livequery plugin does this and has support for more events.
This is a bug in .NET. When PowerShell launches, it caches the output handle (Console.Out). The Encoding property of that text writer does not pick up the value StandardOutputEncoding property.
When you change it from within PowerShell, the Encoding property of the cached output writer returns the cached value, so the output is still encoded with the default encoding.
As a workaround, I would suggest not changing the encoding. It will be returned to you as a Unicode string, at which point you can manage the encoding yourself.
Caching example:
102 [C:\Users\leeholm]
>> $r1 = [Console]::Out
103 [C:\Users\leeholm]
>> $r1
Encoding FormatProvider
-------- --------------
System.Text.SBCSCodePageEncoding en-US
104 [C:\Users\leeholm]
>> [Console]::OutputEncoding = [System.Text.Encoding]::UTF8
105 [C:\Users\leeholm]
>> $r1
Encoding FormatProvider
-------- --------------
System.Text.SBCSCodePageEncoding en-US

In Visual Studio 2015 (Soulution is under source control, MVC-Project), csano's Update-Package -Reinstall -ProjectName Your.Project.Name worked, but it messed up with some write locks.
I had to delete the "packages"-Folder manually before. (It seemed to be locked because of the source control).
Also, I had to re-install the MVC-Package from the NuGet Package Manager.
You can change the JDK or JRE location using the following steps:
[tomcat-home]\bin directory.
c:\tomcat8\binTomcat8W //ES//Tomcat8note:
in Apache TomEE same steps, but step (3) the command must be: TomEE //ES
This is what I did to get rid of all the lock ref issues:
git gc --prune=now
git remote prune origin
This is probably what you only need to do too.
For me there was a problem with the terminal encoding. Adding UTF-8 to .bashrc solved the problem:
export LC_CTYPE=en_US.UTF-8
Don't forget to reload .bashrc afterwards:
source ~/.bashrc
if you are using matplotlib version 3.1.1 or above, you can try:
import matplotlib.pyplot as plt
from matplotlib.colors import ListedColormap
x = [1, 3, 4, 6, 7, 9]
y = [0, 0, 5, 8, 8, 8]
classes = ['A', 'B', 'C']
values = [0, 0, 1, 2, 2, 2]
colours = ListedColormap(['r','b','g'])
scatter = plt.scatter(x, y,c=values, cmap=colours)
plt.legend(handles=scatter.legend_elements()[0], labels=classes)
You need to use the Navigation component in the template of ObservingComponent ( dont't forget to add a selector to Navigation component .. navigation-component for ex )
<navigation-component (navchange)='onNavGhange($event)'></navigation-component>
And implement onNavGhange() in ObservingComponent
onNavGhange(event) {
console.log(event);
}
Last thing .. you don't need the events attribute in @Componennt
events : ['navchange'],
I also think the original object should not be modified. So to save future manpower here's a combined solution based on Jason Harwig's and Tahir Hasan answers:
Date.prototype.addHours= function(h){
var copiedDate = new Date();
copiedDate.setTime(this.getTime() + (h*60*60*1000));
return copiedDate;
}
The solution given by @annoyingmouse works for me.
But to use the checkbox in the header cell, I also had to fix select.dataTables.css.
It seems that they used :
table.dataTable tbody th.select-checkbox
instead of :
table.dataTable thead th.select-checkbox
So I had to add this to my css :
table.dataTable thead th.select-checkbox {
position: relative;
}
table.dataTable thead th.select-checkbox:before,
table.dataTable thead th.select-checkbox:after {
display: block;
position: absolute;
top: 1.2em;
left: 50%;
width: 12px;
height: 12px;
box-sizing: border-box;
}
table.dataTable tbody td.select-checkbox:before,
table.dataTable thead th.select-checkbox:before {
content: ' ';
margin-top: -6px;
margin-left: -6px;
border: 1px solid black;
border-radius: 3px;
}
In Rails, it has form_for helper, so we could make a function like form_for.
We can make a Form macro, for example in resource/macro/html.php:
(if you don't know how to setup a macro, you can google "laravel 5 Macro")
Form::macro('start', function($record, $resource, $options = array()){
if ((null === $record || !$record->exists()) ? 1 : 0) {
$options['route'] = $resource .'.store';
$options['method'] = 'POST';
$str = Form::open($options);
} else {
$options['route'] = [$resource .'.update', $record->id];
$options['method'] = 'PUT';
$str = Form::model($record, $options);
}
return $str;
});
The Controller:
public function create()
{
$category = null;
return view('admin.category.create', compact('category'));
}
public function edit($id)
{
$category = Category.find($id);
return view('admin.category.edit', compact('category'));
}
Then in the view _form.blade.php:
{!! Form::start($category, 'admin.categories', ['class' => 'definewidth m20']) !!}
// here the Form fields
{{!! Form::close() !!}}
Then view create.blade.php:
@include '_form'
Then view edit.blade.php:
@include '_form'
TCPDF works fine, no dependencies, is free and constantly bugfixed. It has reasonable speed if supplied HTML/CSS contents is well formated. I normally generate from 50 - 300 kB of HTML input (including CSS) and get PDF output within 1-3 secs with 10 - 15 PDF pages.
I strongly recommend using tidy library as HTML pretty formatter before sending anything to TCPDF.
I was unable to access to S3 because
Solution: rm -rf .aws/credentials, then aws uses role.
No special escape sequence is required: you can just type the space directly:
if (char_i_want_to_test == ' ') {
// Do something because it is space
}
In ASCII, space is code 32, so you could specify space by '\x20' or even 32, but you really shouldn't do that.
Aside: the word "whitespace" is a catch all for space, tab, newline, and all of that. When you're referring specifically to the ordinary space character, you shouldn't use the term.
you can use
style="display:none"
Ex:
<asp:TextBox ID="txbProv" runat="server" style="display:none"></asp:TextBox>
I have tried your code and it works just fine. The file is being created without any problem, this is the code I used (it's your code, I just changed the datasource for testing):
public ActionResult ExportToExcel()
{
var products = new System.Data.DataTable("teste");
products.Columns.Add("col1", typeof(int));
products.Columns.Add("col2", typeof(string));
products.Rows.Add(1, "product 1");
products.Rows.Add(2, "product 2");
products.Rows.Add(3, "product 3");
products.Rows.Add(4, "product 4");
products.Rows.Add(5, "product 5");
products.Rows.Add(6, "product 6");
products.Rows.Add(7, "product 7");
var grid = new GridView();
grid.DataSource = products;
grid.DataBind();
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
Response.ContentType = "application/ms-excel";
Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
grid.RenderControl(htw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
return View("MyView");
}
Try this code. It works for me:
unzip(zipfile="<directory and filename>",
exdir="<directory where the content will be extracted>")
Example:
unzip(zipfile="./data/Data.zip",exdir="./data")
On Version 1.9.6.1. For UnPushed commit.
Use apply function,
Xlower = df['x'].apply(lambda x: x.upper()).head(10)
Here it is:
select player_name, player_salary, (player_salary * 1.1) as player_newsalary
from player
order by player_name, player_salary, player_newsalary desc
You don't need to "group by" if there is only one instance of a player in the table.
Before actually answering your question:
Parameters in a URL (e.g. key=listOfUsers/user1) are GET parameters and you shouldn't be using them for POST requests. A quick explanation of the difference between GET and POST can be found here.
In your case, to make use of REST principles, you should probably have:
http://ip:5000/users
http://ip:5000/users/<user_id>
Then, on each URL, you can define the behaviour of different HTTP methods (GET, POST, PUT, DELETE). For example, on /users/<user_id>, you want the following:
GET /users/<user_id> - return the information for <user_id>
POST /users/<user_id> - modify/update the information for <user_id> by providing the data
PUT - I will omit this for now as it is similar enough to `POST` at this level of depth
DELETE /users/<user_id> - delete user with ID <user_id>
So, in your example, you want do a POST to /users/user_1 with the POST data being "John". Then the XPath expression or whatever other way you want to access your data should be hidden from the user and not tightly couple to the URL. This way, if you decide to change the way you store and access data, instead of all your URL's changing, you will simply have to change the code on the server-side.
Now, the answer to your question: Below is a basic semi-pseudocode of how you can achieve what I mentioned above:
from flask import Flask
from flask import request
app = Flask(__name__)
@app.route('/users/<user_id>', methods = ['GET', 'POST', 'DELETE'])
def user(user_id):
if request.method == 'GET':
"""return the information for <user_id>"""
.
.
.
if request.method == 'POST':
"""modify/update the information for <user_id>"""
# you can use <user_id>, which is a str but could
# changed to be int or whatever you want, along
# with your lxml knowledge to make the required
# changes
data = request.form # a multidict containing POST data
.
.
.
if request.method == 'DELETE':
"""delete user with ID <user_id>"""
.
.
.
else:
# POST Error 405 Method Not Allowed
.
.
.
There are a lot of other things to consider like the POST request content-type but I think what I've said so far should be a reasonable starting point. I know I haven't directly answered the exact question you were asking but I hope this helps you. I will make some edits/additions later as well.
Thanks and I hope this is helpful. Please do let me know if I have gotten something wrong.
You need to create a class that extends from Exception. It should look like this:
public class MyOwnException extends Exception {
public MyOwnException () {
}
public MyOwnException (String message) {
super (message);
}
public MyOwnException (Throwable cause) {
super (cause);
}
public MyOwnException (String message, Throwable cause) {
super (message, cause);
}
}
Your question does not specify if this new exception should be checked or unchecked.
As you can see here, the two types are different:
Checked exceptions are meant to flag a problematic situation that should be handled by the developer who calls your method. It should be possible to recover from such an exception. A good example of this is a FileNotFoundException. Those exceptions are subclasses of Exception.
Unchecked exceptions are meant to represent a bug in your code, an unexpected situation that you might not be able to recover from. A NullPointerException is a classical example. Those exceptions are subclasses of RuntimeException
Checked exception must be handled by the calling method, either by catching it and acting accordingly, or by throwing it to the calling method. Unchecked exceptions are not meant to be caught, even though it is possible to do so.
public static bool AreAllCellsEmpty(DataRow row)
{
if (row == null) throw new ArgumentNullException("row");
for (int i = row.Table.Columns.Count - 1; i >= 0; i--)
if (!row.IsNull(i))
return false;
return true;
}
SET @seq := 0;
SELECT @seq := FLOOR(@seq + 1) AS sequence, yt.*
FROM your_table yt;
SELECT @seq := FLOOR(@seq + 1) AS sequence, yt.*
FROM (SELECT @seq := 0) s, your_table yt;
The FLOOR() function is used here to get an INTEGER in place of a FLOAT. Sometimes it is needed.
My answer was inspired by David Poor answer. Thanks David!
Think about what a pinch event is: two fingers on an element, moving toward or away from each other.
Gesture events are, to my knowledge, a fairly new standard, so probably the safest way to go about this is to use touch events like so:
(ontouchstart event)
if (e.touches.length === 2) {
scaling = true;
pinchStart(e);
}
(ontouchmove event)
if (scaling) {
pinchMove(e);
}
(ontouchend event)
if (scaling) {
pinchEnd(e);
scaling = false;
}
To get the distance between the two fingers, use the hypot function:
var dist = Math.hypot(
e.touches[0].pageX - e.touches[1].pageX,
e.touches[0].pageY - e.touches[1].pageY);
function deleteValyeFromArray($array,$value)
{
foreach($array as $key=>$val)
{
if($val == $value)
{
unset($array[$key]);
}
}
return $array;
}
Using IIF(RowNumber...) can lead to some issues when rows are being grouped and another alternative is to use a simple VBScript function to determine the color.
It's a little more effort but when the basic solution does not suffice, it's a nice alternative.
Basically, you add code to the Report as follows...
Private bOddRow As Boolean
'*************************************************************************
' -- Display green-bar type color banding in detail rows
' -- Call from BackGroundColor property of all detail row textboxes
' -- Set Toggle True for first item, False for others.
'*************************************************************************
Function AlternateColor(ByVal OddColor As String, _
ByVal EvenColor As String, ByVal Toggle As Boolean) As String
If Toggle Then bOddRow = Not bOddRow
If bOddRow Then
Return OddColor
Else
Return EvenColor
End If
End Function
Then on each cell, set the BackgroundColor as follows:
=Code.AlternateColor("AliceBlue", "White", True)

It's an old question but i faced a very same scenario, i need to split a string using as demiliter the word "low" the problem for me was that i have in the same string the word below and lower.
I solved it using the re module this way
import re
string = '...below...as higher prices mean lower demand to be expected. Generally, a high reading is seen as negative (or bearish), while a low reading is seen as positive (or bullish) for the Korean Won.'
use re.split with regex to match the exact word
stringafterword = re.split('\\blow\\b',string)[-1]
print(stringafterword)
' reading is seen as positive (or bullish) for the Korean Won.'
the generic code is:
re.split('\\bTHE_WORD_YOU_WANT\\b',string)[-1]
Hope this can help someone!
I've adapter the answer of ltiong_sh to work for me:
function nextField(current){
var elements = document.getElementById("my-form").elements;
var exit = false;
for(i = 0; i < elements.length; i++){
if (exit) {
elements[i].focus();
if (elements[i].type == 'text'){
elements[i].select();
}
break;
}
if (elements[i].isEqualNode(current)) {
exit = true;
}
}
}
You can globally set printing options. I think this should work:
Method 1:
pd.set_option('display.max_columns', None)
pd.set_option('display.max_rows', None)
Method 2:
pd.options.display.max_columns = None
pd.options.display.max_rows = None
This will allow you to see all column names & rows when you are doing .head(). None of the column name will be truncated.
If you just want to see the column names you can do:
print(df.columns.tolist())
With sqlserver 2005 and later you can use regex-like character classes with LIKE operator. See here.
To check if a string is a non-negative integer (it is a sequence of decimal digits) you can test that it doesn't contain other characters.
SELECT numstr
FROM table
WHERE numstr NOT LIKE '%[^0-9]%'
Note1: This will return empty strings too.
Note2: Using LIKE '%[0-9]%' will return any string that contains at least a digit.
See fiddle
Using Kotlin to replace a Fragment with another to the container , you can do
button.setOnClickListener {
activity!!
.supportFragmentManager
.beginTransaction()
.replace(R.id.container, NewFragment.newInstance())
.commitNow()
}
Considering the fact you asked for something simple to do what you wanted, you could just:
import datetime
str(datetime.date.today())
Another alternative, which is also quite popular is the Java Service Wrapper. This is also quite popular around the OSS community.
You need to convert all the values in the column to date in order to sort by date.
ES6 React.Component doesn't auto bind methods to itself. You need to bind them yourself in constructor. Like this:
constructor (props){
super(props);
this.state = {
loopActive: false,
shuffleActive: false,
};
this.onToggleLoop = this.onToggleLoop.bind(this);
}
May be I come later to answer but right now I'm facing with this... if helps there are one more solution (the way i solved it).
var query2 = (
from users in Repo.T_Benutzer
join mappings in Repo.T_Benutzer_Benutzergruppen on mappings.BEBG_BE equals users.BE_ID into tmpMapp
join groups in Repo.T_Benutzergruppen on groups.ID equals mappings.BEBG_BG into tmpGroups
from mappings in tmpMapp.DefaultIfEmpty()
from groups in tmpGroups.DefaultIfEmpty()
select new
{
UserId = users.BE_ID
,UserName = users.BE_User
,UserGroupId = mappings.BEBG_BG
,GroupName = groups.Name
}
);
By the way, I tried using the Stefan Steiger code which also helps but it was slower as hell.
The algorithms with m-n can runs awfully long.
This one performs much better:
def gcd(x, y):
while y != 0:
(x, y) = (y, x % y)
return x
There is no i in xpath is not entirely true. You can still use the count() to find the index.

</html>The page has 2 tables and has 6 columns each with unique column names and 6 rows with variable data. The last row has the Modify button in both the tables.
Assuming that the user has to select the 4th Modify button from the first table based on the heading
Use the xpath //th[.='Heading 4']/ancestor::thead/following-sibling::tbody/tr/td[count(//tr/th[.='Heading 4']/preceding-sibling::th)+1]/button
The count() operator comes in handy in situations like these.
Logic:
Modify button using //th[.='Heading 4']count(//tr/th[.='Heading 4']/preceding-sibling::th)+1Note: Index starts at
0
Get the rows for the corresponding header using //th[.='Heading 4']/ancestor::thead/following-sibling::tbody/tr/td[count(//tr/th[.='Heading 4']/preceding-sibling::th)+1]
Get the Modify button from the extracted node list using //th[.='Heading 4']/ancestor::thead/following-sibling::tbody/tr/td[count(//tr/th[.='Heading 4']/preceding-sibling::th)+1]/button
You can just follow instructions from the Homebrew on Linux docs, but I think it is better to understand what the instructions are trying to achieve.
Step 1: Choose location
First of all, it is important to understand that linuxbrew will be installed on the /home directory and not inside /home/your-user (the ~ directory).
(See the reason for that at the end of answer).
Keep this in mind when you run the other steps below.
Step 2: Add linuxbrew binaries to /home :
The installation script will do it for us:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Step 3: Check that /linuxbrew was added to the relevant location
This can be done by simply navigating to /home.
Notice that the docs are showing it as a one-liner by adding test -d <linuxbrew location> before each command.
(Read more about the test command in here).
Step 4: Export relevant environment variables to terminal
We need to add linuxbrew to PATH and add some more environment variables to the current terminal.
We can just add the following exports to terminal (wait don't do it..):
export PATH="/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin${PATH+:$PATH}";
export HOMEBREW_PREFIX="/home/linuxbrew/.linuxbrew";
export HOMEBREW_CELLAR="/home/linuxbrew/.linuxbrew/Cellar";
export HOMEBREW_REPOSITORY="/home/linuxbrew/.linuxbrew/Homebrew";
export MANPATH="/home/linuxbrew/.linuxbrew/share/man${MANPATH+:$MANPATH}:";
export INFOPATH="/home/linuxbrew/.linuxbrew/share/info:${INFOPATH:-}";
Or simply run (If your linuxbrew folder is on other location then /home - change the path):
eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)
(*) Because brew command is not yet identified by the current terminal (this is what we're solving right now) we'll have to specify the full path to the brew binary: /home/linuxbrew/.linuxbrew/bin/brew shellenv
Test this step by:
1 ) Run brew from current terminal to see if it identifies the command.
2 ) Run printenv and check if all environment variables were exported and that you see /home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin on PATH.
Step 5: Ensure step 4 is running on each terminal
We need to add step 4 to ~/.profile (in case of Debian/Ubuntu):
echo "eval \$($(brew --prefix)/bin/brew shellenv)" >> ~/.profile
For CentOS/Fedora/Red Hat - replace ~/.profile with ~/.bash_profile.
Step 6: Ensure that ~/.profile or ~/.bash_profile are being executed when new terminal is opened
If you executed step 5 and failed to run brew from new terminal - add a test command like echo "Hi!" to ~/.profile or ~/.bash_profile.
If you don't see Hi! when you open a new terminal - go to the terminal preferences and ensure that the attribute of 'run command as login shell' is set.

Why the installation script installs Homebrew to /home/linuxbrew/.linuxbrew - from here:
The installation script installs Homebrew to
/home/linuxbrew/.linuxbrewusingsudoif possible and in your home directory at~/.linuxbrewotherwise. Homebrew does not usesudoafter installation.
Using/home/linuxbrew/.linuxbrewallows the use of more binary packages (bottles) than installing in your personal home directory.The prefix
/home/linuxbrew/.linuxbrewwas chosen so that users without admin access can ask an admin to create a linuxbrew role account and still benefit from precompiled binaries.If you do not yourself have admin privileges, consider asking your admin staff to create a linuxbrew role account for you with home directory
/home/linuxbrew.

In most cases it is better to check whether a given functionality is present or not. For example: if the function pipe() exists or not.
I tried many different solutions and this for me was the best:
SpannableStringBuilder ssb = new SpannableStringBuilder(" Hello world!");
ssb.setSpan(new ImageSpan(context, R.drawable.image), 0, 1, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
tv_text.setText(ssb, TextView.BufferType.SPANNABLE);
This code uses a minimum of memory.
you can go:
var cp = require('child_process');
and then:
cp.exec('./myScript.sh', function(err, stdout, stderr) {
// handle err, stdout, stderr
});
to run a command in your $SHELL.
Or go
cp.spawn('./myScript.sh', [args], function(err, stdout, stderr) {
// handle err, stdout, stderr
});
to run a file WITHOUT a shell.
Or go
cp.execFile();
which is the same as cp.exec() but doesn't look in the $PATH.
You can also go
cp.fork('myJS.js', function(err, stdout, stderr) {
// handle err, stdout, stderr
});
to run a javascript file with node.js, but in a child process (for big programs).
You might also have to access stdin and stdout with event listeners. e.g.:
var child = cp.spawn('./myScript.sh', [args]);
child.stdout.on('data', function(data) {
// handle stdout as `data`
});
Spring is a light weight and open source framework created by Rod Johnson in 2003. Spring is a complete and a modular framework, Spring framework can be used for all layer implementations for a real time application or spring can be used for the development of particular layer of a real time application.
Struts is an open-source web application framework for developing Java EE web applications. It uses and extends the Java Servlet API to encourage developers to adopt a model–view–controller (MVC) architecture. It was originally created by Craig McClanahan and donated to the Apache Foundation in May, 2000.
Listed below is the comparison chart of difference between Spring and Strut Framework

I was able to successfully change the section background color with an added blur effect (which is really cool). To change the background color of section easily:
Then for blur effect, add to code:
override func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
// This is the blur effect
let blurEffect = UIBlurEffect(style: .Light)
let blurEffectView = UIVisualEffectView(effect: blurEffect)
// Gets the header view as a UITableViewHeaderFooterView and changes the text colour and adds above blur effect
let headerView: UITableViewHeaderFooterView = view as! UITableViewHeaderFooterView
headerView.textLabel!.textColor = UIColor.darkGrayColor()
headerView.textLabel!.font = UIFont(name: "HelveticaNeue-Light", size: 13)
headerView.tintColor = .groupTableViewBackgroundColor()
headerView.backgroundView = blurEffectView
}

$("#myid li").click(function() {
alert(this.id); // id of clicked li by directly accessing DOMElement property
alert($(this).attr('id')); // jQuery's .attr() method, same but more verbose
alert($(this).html()); // gets innerHTML of clicked li
alert($(this).text()); // gets text contents of clicked li

If you are talking about replacing the ID with something:
$("#myid li").click(function() {
this.id = 'newId';
// longer method using .attr()
$(this).attr('id', 'newId');
});
Demo here. And to be fair, you should have first tried reading the documentation:
__pycache__ is a folder containing Python 3 bytecode compiled and ready to be executed.
I don't recommend routinely deleting these files or suppressing creation during development as it may hurt performance. Just have a recursive command ready (see below) to clean up when needed as bytecode can become stale in edge cases (see comments).
Python programmers usually ignore bytecode. Indeed __pycache__ and *.pyc are common lines to see in .gitignore files. Bytecode is not meant for distribution and can be disassembled using dis module.
If you are using OS X you can easily hide all of these folders in your project by running following command from the root folder of your project.
find . -name '__pycache__' -exec chflags hidden {} \;
Replace __pycache__ with *.pyc for Python 2.
This sets a flag on all those directories (.pyc files) telling Finder/Textmate 2 to exclude them from listings. Importantly the bytecode is there, it's just hidden.
Rerun the command if you create new modules and wish to hide new bytecode or if you delete the hidden bytecode files.
On Windows the equivalent command might be (not tested, batch script welcome):
dir * /s/b | findstr __pycache__ | attrib +h +s +r
Which is same as going through the project hiding folders using right-click > hide...
Running unit tests is one scenario (more in comments) where deleting the *.pyc files and __pycache__ folders is indeed useful. I use the following lines in my ~/.bash_profile and just run cl to clean up when needed.
alias cpy='find . -name "__pycache__" -delete'
alias cpc='find . -name "*.pyc" -delete'
...
alias cl='cpy && cpc && ...'

It is mentioned in the .data() documentation
The data- attributes are pulled in the first time the data property is accessed and then are no longer accessed or mutated (all data values are then stored internally in jQuery)
This was also covered on Why don't changes to jQuery $.fn.data() update the corresponding html 5 data-* attributes?
The demo on my original answer below doesn't seem to work any more.
Updated answer
Again, from the .data() documentation
The treatment of attributes with embedded dashes was changed in jQuery 1.6 to conform to the W3C HTML5 specification.
So for <div data-role="page"></div> the following is true $('div').data('role') === 'page'
I'm fairly sure that $('div').data('data-role') worked in the past but that doesn't seem to be the case any more. I've created a better showcase which logs to HTML rather than having to open up the Console and added an additional example of the multi-hyphen to camelCase data- attributes conversion.
Also see jQuery Data vs Attr?
HTML
<div id="changeMe" data-key="luke" data-another-key="vader"></div>
<a href="#" id="changeData"></a>
<table id="log">
<tr><th>Setter</th><th>Getter</th><th>Result of calling getter</th><th>Notes</th></tr>
</table>
JavaScript (jQuery 1.6.2+)
var $changeMe = $('#changeMe');
var $log = $('#log');
var logger;
(logger = function(setter, getter, note) {
note = note || '';
eval('$changeMe' + setter);
var result = eval('$changeMe' + getter);
$log.append('<tr><td><code>' + setter + '</code></td><td><code>' + getter + '</code></td><td>' + result + '</td><td>' + note + '</td></tr>');
})('', ".data('key')", "Initial value");
$('#changeData').click(function() {
// set data-key to new value
logger(".data('key', 'leia')", ".data('key')", "expect leia on jQuery node object but DOM stays as luke");
// try and set data-key via .attr and get via some methods
logger(".attr('data-key', 'yoda')", ".data('key')", "expect leia (still) on jQuery object but DOM now yoda");
logger("", ".attr('key')", "expect undefined (no attr <code>key</code>)");
logger("", ".attr('data-key')", "expect yoda in DOM and on jQuery object");
// bonus points
logger('', ".data('data-key')", "expect undefined (cannot get via this method)");
logger(".data('anotherKey')", ".data('anotherKey')", "jQuery 1.6+ get multi hyphen <code>data-another-key</code>");
logger(".data('another-key')", ".data('another-key')", "jQuery < 1.6 get multi hyphen <code>data-another-key</code> (also supported in jQuery 1.6+)");
return false;
});
$('#changeData').click();
Original answer
For this HTML:
<div id="foo" data-helptext="bar"></div>
<a href="#" id="changeData">change data value</a>
and this JavaScript (with jQuery 1.6.2)
console.log($('#foo').data('helptext'));
$('#changeData').click(function() {
$('#foo').data('helptext', 'Testing 123');
// $('#foo').attr('data-helptext', 'Testing 123');
console.log($('#foo').data('data-helptext'));
return false;
});
Using the Chrome DevTools Console to inspect the DOM, the $('#foo').data('helptext', 'Testing 123'); does not update the value as seen in the Console but $('#foo').attr('data-helptext', 'Testing 123'); does.
Try as given below:
while (MyReader.Read())
{
TextBox1.Text = Convert.ToDateTime(MyReader["DateField"]).ToString("dd/MM/yyyy");
}
in ToString() method you can change data format as per your requirement.
The traditional approach is full of boilerplate code and clumsy resource handling. That's why I made the Spyglass framework. To demonstrate how it works, here's an example showing how to make a custom view that displays a String title.
Step 1: Create a custom view class.
public class CustomView extends FrameLayout {
private TextView titleView;
public CustomView(Context context) {
super(context);
init(null, 0, 0);
}
public CustomView(Context context, AttributeSet attrs) {
super(context, attrs);
init(attrs, 0, 0);
}
public CustomView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(attrs, defStyleAttr, 0);
}
@RequiresApi(21)
public CustomView(
Context context,
AttributeSet attrs,
int defStyleAttr,
int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
init(attrs, defStyleAttr, defStyleRes);
}
public void setTitle(String title) {
titleView.setText(title);
}
private void init(AttributeSet attrs, int defStyleAttr, int defStyleRes) {
inflate(getContext(), R.layout.custom_view, this);
titleView = findViewById(R.id.title_view);
}
}
Step 2: Define a string attribute in the values/attrs.xml resource file:
<resources>
<declare-styleable name="CustomView">
<attr name="title" format="string"/>
</declare-styleable>
</resources>
Step 3: Apply the @StringHandler annotation to the setTitle method to tell the Spyglass framework to route the attribute value to this method when the view is inflated.
@HandlesString(attributeId = R.styleable.CustomView_title)
public void setTitle(String title) {
titleView.setText(title);
}
Now that your class has a Spyglass annotation, the Spyglass framework will detect it at compile-time and automatically generate the CustomView_SpyglassCompanion class.
Step 4: Use the generated class in the custom view's init method:
private void init(AttributeSet attrs, int defStyleAttr, int defStyleRes) {
inflate(getContext(), R.layout.custom_view, this);
titleView = findViewById(R.id.title_view);
CustomView_SpyglassCompanion
.builder()
.withTarget(this)
.withContext(getContext())
.withAttributeSet(attrs)
.withDefaultStyleAttribute(defStyleAttr)
.withDefaultStyleResource(defStyleRes)
.build()
.callTargetMethodsNow();
}
That's it. Now when you instantiate the class from XML, the Spyglass companion interprets the attributes and makes the required method call. For example, if we inflate the following layout then setTitle will be called with "Hello, World!" as the argument.
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:width="match_parent"
android:height="match_parent">
<com.example.CustomView
android:width="match_parent"
android:height="match_parent"
app:title="Hello, World!"/>
</FrameLayout>
The framework isn't limited to string resources has lots of different annotations for handling other resource types. It also has annotations for defining default values and for passing in placeholder values if your methods have multiple parameters.
Have a look at the Github repo for more information and examples.
I'm not sure what you want to accomplish, but in this case just adding width: 100%; to your ul#slideshow li will do the trick.
The img tags are inline-block elements. This means that they flow inline like text, but also have a width and height like block elements. In your css there are two text-align: center; rules applied to the <body> and to the #slideshowWrapper (which is redundant btw) this makes all inline and inline-block child elements to be centered in their closest block elements, in your code these are li tags. All block elements have width: 100% if they are the static flow (position: static;), which is default. The problem is that when you tell li tags to be position: absolute;, you take them out of normal static flow, and this causes them to shrink their size to just fit their inner content, in other words they kind of "lose" their width: 100% property.

The pdfrw library can do this quite easily, assuming you don't need to preserve bookmarks and annotations, and your PDFs aren't encrypted. cat.py is an example concatenation script, and subset.py is an example page subsetting script.
The relevant part of the concatenation script -- assumes inputs is a list of input filenames, and outfn is an output file name:
from pdfrw import PdfReader, PdfWriter
writer = PdfWriter()
for inpfn in inputs:
writer.addpages(PdfReader(inpfn).pages)
writer.write(outfn)
As you can see from this, it would be pretty easy to leave out the last page, e.g. something like:
writer.addpages(PdfReader(inpfn).pages[:-1])
Disclaimer: I am the primary pdfrw author.
A better approach to find whether one of the subinstallers is blocked is to monitor its Network and Disk I/O activity. Process Explorer from Sysinternals does an excellent job. Android SDK Setup downloads large amounts of data (more than 1GB) and the CPU sits idle waiting for an I/O-bound operation to be completed. Under no circumstances you should attempt to kill any process, or you might risk corrupting your installation of Visual Studio. In the worst case scenario, cancelling and rerunning the setup should help.
To get all the records where record created date is today's date Use the code after WHERE clause
WHERE CAST(Submission_date AS DATE) = CAST( curdate() AS DATE)
Fairly new to using PowerShell, think I might be able to help. Could you try this?
I believe you're not getting the correct parameters to your script block:
param([string]$one, [string]$two)

If you have a PEM file (e.g. server.pem) containing:
then you can import the certificate and key into a JKS keystore like this:
1) Copy the private key from the PEM file into an ascii file (e.g. server.key)
2) Copy the cert from the PEM file into an ascii file (e.g. server.crt)
3) Export the cert and key into a PKCS12 file:
$ openssl pkcs12 -export -in server.crt -inkey server.key \
-out server.p12 -name [some-alias] -CAfile server.pem -caname root
-CAfile option.winpty to the start of the command so the export password can be entered.4) Convert the PKCS12 file to a JKS keystore:
$ keytool -importkeystore -deststorepass changeit -destkeypass changeit \
-destkeystore keystore.jks -srckeystore server.p12 -srcstoretype PKCS12 \
-srcstorepass changeit
srcstorepass password should match the export password from step 3)I used Keystore Explorer
Just to note that prefixing the tagName in a selector is slower than just using the id. In your case jQuery will get all the inputs rather than just using the getElementById. Just use $('#textbox')

query.setParameter("xxx", "%"+abc+"%");

I recently purchased a MacBook Air (mid-2011 model) and was really happy to find that Apple officially supports Windows 7. If you purchase Windows 7 (I got DSP), you can use the Boot Camp assistant in OSX to designate part of your hard drive to Windows. Then you can install and run Windows 7 natively as if it were as Windows notebook.
I use Visual Studio 2010 on Windows 7 on my MacBook Air (I kept OSX as well) and I could not be happier. Heck, the initial start-up of the program only takes 3 seconds thanks to the SSD.
As others have mentions, you can run it on OSX using Parallels, etc. but I prefer to run it natively.
I recommend you create an enum for your car colours instead of using Strings and the natural ordering of the enum will be the order in which you declare the constants.
public enum PaintColors {
SILVER, BLUE, MAGENTA, RED
}
and
static class ColorComparator implements Comparator<CarSort>
{
public int compare(CarSort c1, CarSort c2)
{
return c1.getColor().compareTo(c2.getColor());
}
}
You change the String to PaintColor and then in main your car list becomes:
carList.add(new CarSort("Ford Figo",PaintColor.SILVER));
...
Collections.sort(carList, new ColorComparator());
Your code doesn't seem so ugly to me...

}
private string GetOutline(int indentLevel, XElement element)

{
result = result.AppendLine(new string(' ', indentLevel * 2) + element.Attribute("name").Value);

Your data is poorly formed. The value fields in particular have numerous spaces and new lines. Automated formatters won't work on this, as they will not modify the actual data. As you generate the data for output, filter it as needed to avoid the spaces.
The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard.
.jpeg and .jpg files are identical.
JPEG images are identified with 6 different standard file name extensions:
.jpg.jpeg.jpe.jif.jfif.jfiThe jpg was used in Microsoft Operating Systems when they only supported 3 chars-extensions.
The JPEG File Interchange Format (JFIF - last three extensions in my list) is an image file format standard for exchanging JPEG encoded files compliant with the JPEG Interchange Format (JIF) standard, solving some of JIF's limitations in regard. Image data in JFIF files is compressed using the techniques in the JPEG standard, hence JFIF is sometimes referred to as "JPEG/JFIF".
I think Java is fine as it is, adding unsigned would complicate it without much gain. Even with the simplified integer model, most Java programmers don't know how the basic numeric types behave - just read the book Java Puzzlers to see what misconceptions you might hold.
As for practical advice:
If your values are somewhat arbitrary size and don't fit into int, use long.
If they don't fit into long use BigInteger.
Use the smaller types only for arrays when you need to save space.
If you need exactly 64/32/16/8 bits, use long/int/short/byte and stop worrying about the sign bit, except for division, comparison, right shift, and casting.

If you need to rename ALL columns at once,
DataFrame.set_axis() method with axis=1. Pass a list-like sequence. Options are available for in-place modification as well.rename with axis=1df = pd.DataFrame('x', columns=['y', 'gdp', 'cap'], index=range(5))
df
y gdp cap
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
With 0.21+, you can now specify an axis parameter with rename:
df.rename({'gdp':'log(gdp)'}, axis=1)
# df.rename({'gdp':'log(gdp)'}, axis='columns')
y log(gdp) cap
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
(Note that rename is not in-place by default, so you will need to assign the result back.)
This addition has been made to improve consistency with the rest of the API. The new axis argument is analogous to the columns parameter—they do the same thing.
df.rename(columns={'gdp': 'log(gdp)'})
y log(gdp) cap
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
rename also accepts a callback that is called once for each column.
df.rename(lambda x: x[0], axis=1)
# df.rename(lambda x: x[0], axis='columns')
y g c
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
For this specific scenario, you would want to use
df.rename(lambda x: 'log(gdp)' if x == 'gdp' else x, axis=1)
Index.str.replaceSimilar to replace method of strings in python, pandas Index and Series (object dtype only) define a ("vectorized") str.replace method for string and regex-based replacement.
df.columns = df.columns.str.replace('gdp', 'log(gdp)')
df
y log(gdp) cap
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
The advantage of this over the other methods is that str.replace supports regex (enabled by default). See the docs for more information.
set_axis with axis=1Call set_axis with a list of header(s). The list must be equal in length to the columns/index size. set_axis mutates the original DataFrame by default, but you can specify inplace=False to return a modified copy.
df.set_axis(['cap', 'log(gdp)', 'y'], axis=1, inplace=False)
# df.set_axis(['cap', 'log(gdp)', 'y'], axis='columns', inplace=False)
cap log(gdp) y
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
Note: In future releases, inplace will default to True.
Method Chaining
Why choose set_axis when we already have an efficient way of assigning columns with df.columns = ...? As shown by Ted Petrou in this answer set_axis is useful when trying to chain methods.
Compare
# new for pandas 0.21+
df.some_method1()
.some_method2()
.set_axis()
.some_method3()
Versus
# old way
df1 = df.some_method1()
.some_method2()
df1.columns = columns
df1.some_method3()
The former is more natural and free flowing syntax.
I found, bizarrely, that I could fix the errors by placing the timezone declaration at the TOP of my php.ini file.
It was already in my php.ini. Twice, actually. And I was pulling my hair out because everyone was saying there must be another ini being loaded... There wasn't.
Hope this can save someone else the time/hair loss.

I had the same problems, but using easy_install "module" solved the problem for me.
I am not sure why, but pip and easy_install use different install locations, and easy_install chose the right ones.
Edit: without re-checking but because of the comments; it seems that different (OSX and brew-installed) installations interfere with each other which is why they tools mentioned indeed point to different locations (since they belong to different installations). I understand that usually those tools from one install point to the same folder.
Use: LOGGER.log(Level.INFO, "Got an exception.", e);
or LOGGER.info("Got an exception. " + e.getMessage());
Is WebSockets over TCP a fast enough protocol to stream a video of, say, 30fps?
Yes.. it is, take a look at this project. Websockets can easily handle HD videostreaming.. However, you should go for Adaptive Streaming. I explain here how you could implement it.
Currently we're working on a webbased instant messaging application with chat, filesharing and video/webcam support. With some bits and tricks we got streaming media through websockets (used HTML5 Media Capture to get the stream from our webcams).
You need to build a stream API and a Media Stream Transceiver to control the related media processing and transport.
If you wanted a framework-esq syntax (Note: IE 8+ support only), you could extend the Element prototype and add your own setAttributes function:
Element.prototype.setAttributes = function (attrs) {
for (var idx in attrs) {
if ((idx === 'styles' || idx === 'style') && typeof attrs[idx] === 'object') {
for (var prop in attrs[idx]){this.style[prop] = attrs[idx][prop];}
} else if (idx === 'html') {
this.innerHTML = attrs[idx];
} else {
this.setAttribute(idx, attrs[idx]);
}
}
};
This lets you use syntax like this:
var d = document.createElement('div');
d.setAttributes({
'id':'my_div',
'class':'my_class',
'styles':{
'backgroundColor':'blue',
'color':'red'
},
'html':'lol'
});
Try it: http://jsfiddle.net/ywrXX/1/
If you don't like extending a host object (some are opposed) or need to support IE7-, just use it as a function
Note that setAttribute will not work for style in IE, or event handlers (you shouldn't anyway). The code above handles style, but not events.
Documentation
setAttribute on MDN - https://developer.mozilla.org/en-US/docs/DOM/element.setAttributeIf using the Win32 API you can use the FindFirstFile and FindNextFile functions.
http://msdn.microsoft.com/en-us/library/aa365200(VS.85).aspx
For recursive traversal of directories you must inspect each WIN32_FIND_DATA.dwFileAttributes to check if the FILE_ATTRIBUTE_DIRECTORY bit is set. If the bit is set then you can recursively call the function with that directory. Alternatively you can use a stack for providing the same effect of a recursive call but avoiding stack overflow for very long path trees.

instead of receiving the json string a model binding is better. For example:
[HttpPost]
public ActionResult AddUser(UserAddModel model)
{
if (ModelState.IsValid) {
return Json(new { Response = "Success" });
}
return Json(new { Response = "Error" });
}
<script>
function submitForm() {
$.ajax({
type: 'POST',
url: "@Url.Action("AddUser")",
contentType: "application/json; charset=utf-8",
dataType: 'json',
data: $("form[name=UserAddForm]").serialize(),
success: function (data) {
console.log(data);
}
});
}
</script>
If you define a class without any constructor, the compiler will synthesize a constructor for you (and that will be a default constructor -- i.e., one that doesn't require any arguments). If, however, you do define a constructor, (even if it does take one or more arguments) the compiler will not synthesize a constructor for you -- at that point, you've taken responsibility for constructing objects of that class, so the compiler "steps back", so to speak, and leaves that job to you.
You have two choices. You need to either provide a default constructor, or you need to supply the correct parameter when you define an object. For example, you could change your constructor to look something like:
Blowfish(BlowfishAlgorithm algorithm = CBC);
...so the ctor could be invoked without (explicitly) specifying an algorithm (in which case it would use CBC as the algorithm).
The other alternative would be to explicitly specify the algorithm when you define a Blowfish object:
class GameCryptography {
Blowfish blowfish_;
public:
GameCryptography() : blowfish_(ECB) {}
// ...
};
In C++ 11 (or later) you have one more option available. You can define your constructor that takes an argument, but then tell the compiler to generate the constructor it would have if you didn't define one:
class GameCryptography {
public:
// define our ctor that takes an argument
GameCryptography(BlofishAlgorithm);
// Tell the compiler to do what it would have if we didn't define a ctor:
GameCryptography() = default;
};
As a final note, I think it's worth mentioning that ECB, CBC, CFB, etc., are modes of operation, not really encryption algorithms themselves. Calling them algorithms won't bother the compiler, but is unreasonably likely to cause a problem for others reading the code.
cp dir1/* dir2
Or if you have directories inside dir1 that you'd want to copy as well
cp -r dir1/* dir2
This is a good description of its uses and shortcomings. You essentially use it whenever you need to do fast low-level I/O. If you were going to implement a TCP/IP protocol or if you were writing a database (DBMS) this class would come in handy.

"Using HTML5/Canvas/JavaScript to take screenshots" answers your problem.
You can use JavaScript/Canvas to do the job but it is still experimental.
You typically do commit .gitignore. In fact, I personally go as far as making sure my index is always clean when I'm not working on something. (git status should show nothing.)
There are cases where you want to ignore stuff that really isn't project specific. For example, your text editor may create automatic *~ backup files, or another example would be the .DS_Store files created by OS X.
I'd say, if others are complaining about those rules cluttering up your .gitignore, leave them out and instead put them in a global excludes file.
By default this file resides in $XDG_CONFIG_HOME/git/ignore (defaults to ~/.config/git/ignore), but this location can be changed by setting the core.excludesfile option. For example:
git config --global core.excludesfile ~/.gitignore
Simply create and edit the global excludesfile to your heart's content; it'll apply to every git repository you work on on that machine.

If your XML goes quite deep, you might want to consider using XPath, which comes with your JRE, so you can access the contents far more easily using:
String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()",
document.getDocumentElement());
Full example:
import static org.junit.Assert.assertEquals;
import java.io.StringReader;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathFactory;
import org.junit.Before;
import org.junit.Test;
import org.w3c.dom.Document;
import org.xml.sax.InputSource;
public class XPathTest {
private Document document;
@Before
public void setup() throws Exception {
String xml = "<add job=\"351\"><tag>foobar</tag><tag>foobar2</tag></add>";
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
document = db.parse(new InputSource(new StringReader(xml)));
}
@Test
public void testXPath() throws Exception {
XPathFactory xpf = XPathFactory.newInstance();
XPath xp = xpf.newXPath();
String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()",
document.getDocumentElement());
assertEquals("foobar", text);
}
}
Adding to @zzzzzzz answer, I ran the command:python3 -c "import sys; print(sys.path)" and it provided me with different paths comparing to the same command with python. The paths that were displayed with python3 were "python3 oriented".
See the output of the two different commands:
python -c "import sys; print(sys.path)"
['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/local/lib/python2.7/dist-packages/setuptools-39.1.0-py2.7.egg', '/usr/lib/python2.7/dist-packages']
python3 -c "import sys; print(sys.path)"
['', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']
Both commands were executed on my Ubuntu 18.04 machine.

This is a very simple to create file in git bash at first write touch then file name with extension
for example
touch filename.extension
I've created a library sysend.js, it's very small, you can check its source code. The library don't have any external dependencies.
You can use it for communication between tabs/windows in same browser and domain. The library use BroadcastChannel, if supported, or storage event from localStorage.
API is very simple:
sysend.on('foo', function(message) {
console.log(message);
});
sysend.broadcast('foo', {message: 'Hello'});
sysend.broadcast('foo', "hello");
sysend.broadcast('foo'); // empty notification
when your brower support BroadcastChannel it sent literal object (but it's in fact auto-serialized by browser) and if not it's serialized to JSON first and deserialized on other end.
Recent version also have helper API to create proxy for Cross-Domain communication. (it require single html file on target domain).
Here is demo.
EDIT:
New version also support Cross-Domain communication, if you include special proxy.html file on target domain and call proxy function from source domain:
sysend.proxy('https://target.com');
(proxy.html it's very simple html file, that only have one script tag with the library).
If you want two way communication you need to do the same on other domain.
NOTE: If you will implement same functionality using localStorage, there is issue in IE. Storage event is sent to the same window, which triggered the event and for other browsers it's only invoked for other tabs/windows.
As of Laravel >= 5.3, best way is to use value:
$groupName = \App\User::where('username',$username)->value('groupName');
or
use App\User;//at top of controller
$groupName = User::where('username',$username)->value('groupName');//inside controller function
Of course you have to create a model User for users table which is most efficient way to interact with database tables in Laravel.
Published by Microsoft in Standard Date and Time Format Strings:
dataGrid.Columns[2].DefaultCellStyle.Format = "d"; // Short date
That should format the date according to the person's location settings.
This is part of Microsoft's larger collection of Formatting Types in .NET.
git log path should do what you want. From the git log man:
[--] <path>…
Show only commits that affect any of the specified paths. To prevent confusion with
options and branch names, paths may need to be prefixed with "-- " to separate them
from options or refnames.
I'm sure there's a more efficient way to do it, but I would probably do this:
string getTenDigitNumber(string input)
{
StringBuilder sb = new StringBuilder();
for(int i - 0; i < input.Length; i++)
{
int junk;
if(int.TryParse(input[i], ref junk))
sb.Append(input[i]);
}
return sb.ToString();
}
The actual problem is not IE8, but the hacks that you use for earlier versions of IE.
IE8 is pretty close to be standards compliant, so you shouldn't need any hacks at all for it, perhaps only some tweaks. The problem is if you are using some hacks for IE6 and IE7; you will have to make sure that they only apply to those versions and not IE8.
I made the web site of our company compatible with IE8 a while ago. The only thing that I actually changed was adding the meta tag that tells IE that the pages are IE8 compliant...
WARNING:
git clean -fwill remove untracked files, meaning they're gone for good since they aren't stored in the repository. Make sure you really want to remove all untracked files before doing this.
Try this and see git clean -f.
git reset --hard will not remove untracked files, where as git-clean will remove any files from the tracked root directory that are not under Git tracking.
Alternatively, as @Paul Betts said, you can do this (beware though - that removes all ignored files too)
git clean -dfgit clean -xdf CAUTION! This will also delete ignored filesNote (also a bit off topic): Another way to make unique flags can be done using a bit shift. I, myself, find this easier to read.
enum Flags
{
A = 1 << 0, // binary 0001
B = 1 << 1, // binary 0010
C = 1 << 2, // binary 0100
D = 1 << 3, // binary 1000
};
It can hold values up to an int so that is, most of the time, 32 flags which is clearly reflected in the shift amount.
The following works:
@NonCPS
def printParams() {
env.getEnvironment().each { name, value -> println "Name: $name -> Value $value" }
}
printParams()

In my case I should need wait for a jquery plugin execution in some element.. specifically "qtip"
based in your hint, it worked perfectly for me :
wait.until( new Predicate<WebDriver>() {
public boolean apply(WebDriver driver) {
return ((JavascriptExecutor)driver).executeScript("return document.readyState").equals("complete");
}
}
);
Note: I'm using Webdriver 2
Use a binding, like in this example:
<a href="#new-search" data-bind="click:SearchManager.bind($data,'1')">
Search Manager
</a>
var ViewModelStructure = function () {
var self = this;
this.SearchManager = function (search) {
console.log(search);
};
}();
No, you shouldn't call it explicitly because it would be called twice. Once for the manual call and another time when the scope in which the object is declared ends.
Eg.
{
Class c;
c.~Class();
}
If you really need to perform the same operations you should have a separate method.
There is a specific situation in which you may want to call a destructor on a dynamically allocated object with a placement new but it doesn't sound something you will ever need.
You can simply put javascript expression in ng-model.
The iterator of _.each is called with 3 parameters (element, index, list). So yes, for _.each you cab get the index.
You can do the same in sortBy
If you want to find out how to set-up a non-native cross compile, I found this useful:
On the target machine,
% gcc -march=native -Q --help=target | grep march
-march= core-avx-i
Then use this on the build machine:
% gcc -march=core-avx-i ...
set myDIR=LOG
IF not exist %myDIR% (mkdir %myDIR%)
This appears to be a variable naming convention in Node.js control-flow code, where a reference to the next function to execute is given to a callback for it to kick-off when it's done.
See, for example, the code samples here:
Let's look at the example you posted:
function loadUser(req, res, next) {
if (req.session.user_id) {
User.findById(req.session.user_id, function(user) {
if (user) {
req.currentUser = user;
return next();
} else {
res.redirect('/sessions/new');
}
});
} else {
res.redirect('/sessions/new');
}
}
app.get('/documents.:format?', loadUser, function(req, res) {
// ...
});
The loadUser function expects a function in its third argument, which is bound to the name next. This is a normal function parameter. It holds a reference to the next action to perform and is called once loadUser is done (unless a user could not be found).
There's nothing special about the name next in this example; we could have named it anything.

Welcome to Microsoft Marketing Speak hell. With the 2012 release of SQL Server, the BIDS, Business Intelligence Designer Studio, plugin for Visual Studio was renamed to SSDT, SQL Server Data Tools. SSDT is available for 2010 and 2012. The problem is, there are two different products called SSDT.
There is SSDT which replaces the database designer thing which was called Data Dude in VS 2008 and in 2010 became database projects. That a free install and if you snag the web installer, that's what you get when you install SSDT. It puts the correct project templates and such into Visual Studio.
There's also the SSDT which is the "BIDS" replacement for developing SSIS, SSRS and SSAS stuff. As of March 2013, it is now available for the 2012 release of Visual Studio. The download is labeled SSDTBI_VS2012_X86.msi Perhaps that's a signal on how the product is going to be referred to in marketing materials. Download links are
None the less, we have Business Intelligence projects available to us in Visual Studio 2012. And the people did rejoice and did feast upon the lambs and toads and tree-sloths and fruit-bats and orangutans and breakfast cereals

I wouldn't recommend the HAVING keyword for newbies, it is essentially for legacy purposes.
I am not clear on what is the key for this table (is it fully normalized, I wonder?), consequently I find it difficult to follow your specification:
I would like to find all records for all users that have more than one payment per day with the same account number... Additionally, there should be a filter than only counts the records whose ZIP code is different.
So I've taken a literal interpretation.
The following is more verbose but could be easier to understand and therefore maintain (I've used a CTE for the table PAYMENT_TALLIES but it could be a VIEW:
WITH PAYMENT_TALLIES (user_id, zip, tally)
AS
(
SELECT user_id, zip, COUNT(*) AS tally
FROM PAYMENT
GROUP
BY user_id, zip
)
SELECT DISTINCT *
FROM PAYMENT AS P
WHERE EXISTS (
SELECT *
FROM PAYMENT_TALLIES AS PT
WHERE P.user_id = PT.user_id
AND PT.tally > 1
);

I have made a small benchmark with a file which contains approximately 345 000 lines. The way with grep seems to be around 15 times faster than the sed method in this case.
I have tried both with and without the setting LC_ALL=C, it does not seem change the timings significantly. The search string (CDGA_00004.pdbqt.gz.tar) is somewhere in the middle of the file.
Here are the commands and the timings:
time sed -i "/CDGA_00004.pdbqt.gz.tar/d" /tmp/input.txt
real 0m0.711s
user 0m0.179s
sys 0m0.530s
time perl -ni -e 'print unless /CDGA_00004.pdbqt.gz.tar/' /tmp/input.txt
real 0m0.105s
user 0m0.088s
sys 0m0.016s
time (grep -v CDGA_00004.pdbqt.gz.tar /tmp/input.txt > /tmp/input.tmp; mv /tmp/input.tmp /tmp/input.txt )
real 0m0.046s
user 0m0.014s
sys 0m0.019s
To answer your question, these should work as long as:
But, if I remember correctly, these values can be faked to an extent, so it's best not to rely on them.
My personal preference is to set the domain name as an environment variable in the apache2 virtual host:
# Virtual host
setEnv DOMAIN_NAME example.com
And read it in PHP:
// PHP
echo getenv(DOMAIN_NAME);
This, however, isn't applicable in all circumstances.
this states that Account.deposit(Double.MAX_VALUE);
it is setting deposit value to MAX value of Double dataType.to procced for running tests.
The Multipart File Upload worked after following code modification to Upload using RestTemplate
LinkedMultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
map.add("file", new ClassPathResource(file));
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
HttpEntity<LinkedMultiValueMap<String, Object>> requestEntity = new HttpEntity<LinkedMultiValueMap<String, Object>>(
map, headers);
ResponseEntity<String> result = template.get().exchange(
contextPath.get() + path, HttpMethod.POST, requestEntity,
String.class);
And adding MultipartFilter to web.xml
<filter>
<filter-name>multipartFilter</filter-name>
<filter-class>org.springframework.web.multipart.support.MultipartFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>multipartFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
private String getCurrentStackTraceString() {

I had the same issue and after doing all the stuff written here as answers, it still reproduced. The second half of the issue was the fact that .NET was turned off under "Turn Windows features on or off"
awk '{ sum += $2; n++ } END { if (n > 0) print sum / n; }'
Add the numbers in $2 (second column) in sum (variables are auto-initialized to zero by awk) and increment the number of rows (which could also be handled via built-in variable NR). At the end, if there was at least one value read, print the average.
awk '{ sum += $2 } END { if (NR > 0) print sum / NR }'
If you want to use the shebang notation, you could write:
#!/bin/awk
{ sum += $2 }
END { if (NR > 0) print sum / NR }
You can also control the format of the average with printf() and a suitable format ("%13.6e\n", for example).
You can also generalize the code to average the Nth column (with N=2 in this sample) using:
awk -v N=2 '{ sum += $N } END { if (NR > 0) print sum / NR }'
It is not on PyPI and you should not be installing it via pip. If you have matplotlib installed, you should be able to import mpl_toolkits directly:
$ pip install --upgrade matplotlib
...
$ python

To answer the question How to delete specific columns in vba for excel. I use Array as below.
sub del_col()
dim myarray as variant
dim i as integer
myarray = Array(10, 9, 8)'Descending to Ascending
For i = LBound(myarray) To UBound(myarray)
ActiveSheet.Columns(myarray(i)).EntireColumn.Delete
Next i
end sub
No need of any manual break in code. Just add \n where you want to break.
alert ("Please Select file \n to delete");
This will show the alert like
Please select file
to delete.
If you are talking about Datepicker for bootstrap, you set the start date (the min date) by using the following:
$('#datepicker').datepicker('setStartDate', <DATETIME STRING HERE>);
Socks4 is a very simple protocol to implement. You listen for the initial connection, connect to the host/port that was requested by the client, send the success code to the client then forward the outgoing and incoming streams across sockets.
If you go with HTTP you'll have to read and possibly set/remove some HTTP headers so that's a little more work.
If I remember correctly, SSL will work across HTTP and Socks proxies. For a HTTP proxy you implement the CONNECT verb, which works much like the socks4 as described above, then the client opens the SSL connection across the proxied tcp stream.
This will return the maximum value in a matrix
max(M1(:))
This will return the row and the column of that value
[x,y]=ind2sub(size(M1),max(M1(:)))
For minimum just swap the word max with min and that's all.
With multiple joins, use something like this code:
$someId = 44;
Event::with(["owner", "participants" => function($q) use($someId){
$q->where('participants.IdUser', '=', 1);
//$q->where('some other field', $someId);
}])
split sliceconcentrateThis is a good workout for beginners and it's easy to achieve.
Another advanced method is a function like this:
def trim(s):
return trim(s[slice])
And for this question, you just want to remove the last characters, so you can write like this:
def trim(s):
return s[ : -3]
I think you are over to care about what those three characters are, so you lost. You just want to remove last three, nevertheless who they are!
If you want to remove some specific characters, you can add some if judgements:
def trim(s):
if [conditions]: ### for some cases, I recommend using isinstance().
return trim(s[slice])
I am amazed to see so many string replace ideas of UUID. How about this:
UUID temp = UUID.randomUUID();
String uuidString = Long.toHexString(temp.getMostSignificantBits())
+ Long.toHexString(temp.getLeastSignificantBits());
This is the fasted way of doing it since the whole toString() of UUID is already more expensive not to mention the regular expression which has to be parsed and executed or the replacing with empty string.
Give the parent z-index: -1, or opacity: 0.99
You are just creating your array incorrectly. You could use http_build_query:
$fields = array(
'username' => "annonymous",
'api_key' => urlencode("1234"),
'images' => array(
urlencode(base64_encode('image1')),
urlencode(base64_encode('image2'))
)
);
$fields_string = http_build_query($fields);
So, the entire code that you could use would be:
<?php
//extract data from the post
extract($_POST);
//set POST variables
$url = 'http://api.example.com/api';
$fields = array(
'username' => "annonymous",
'api_key' => urlencode("1234"),
'images' => array(
urlencode(base64_encode('image1')),
urlencode(base64_encode('image2'))
)
);
//url-ify the data for the POST
$fields_string = http_build_query($fields);
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
//execute post
$result = curl_exec($ch);
echo $result;
//close connection
curl_close($ch);
?>
When the directory is deleted, the inode for that directory (and the inodes for its contents) are recycled. The pointer your shell has to that directory's inode (and its contents's inodes) are now no longer valid. When the directory is restored from backup, the old inodes are not (necessarily) reused; the directory and its contents are stored on random inodes. The only thing that stays the same is that the parent directory reuses the same name for the restored directory (because you told it to).
Now if you attempt to access the contents of the directory that your original shell is still pointing to, it communicates that request to the file system as a request for the original inode, which has since been recycled (and may even be in use for something entirely different now). So you get a stale file handle message because you asked for some nonexistent data.
When you perform a cd operation, the shell reevaluates the inode location of whatever destination you give it. Now that your shell knows the new inode for the directory (and the new inodes for its contents), future requests for its contents will be valid.
