There is a way. $q.all(...
You can check the below stuffs:
You can use the Median of Medians algorithm to find median of an unsorted array in linear time.
For UNIX-Like systems you might want to execute "echo ~username
" using the shell (so use Runtime.exec()
to run {"/bin/sh", "-c", "echo ~username"}
).
Using Tyler Dodge's excellent answer kept lagging on my iPad, so I added some throttling code, now it's quite smooth. There is some minimal skipping sometimes while scrolling.
// Uses document because document will be topmost level in bubbling
$(document).on('touchmove',function(e){
e.preventDefault();
});
var scrolling = false;
// Uses body because jquery on events are called off of the element they are
// added to, so bubbling would not work if we used document instead.
$('body').on('touchstart','.scrollable',function(e) {
// Only execute the below code once at a time
if (!scrolling) {
scrolling = true;
if (e.currentTarget.scrollTop === 0) {
e.currentTarget.scrollTop = 1;
} else if (e.currentTarget.scrollHeight === e.currentTarget.scrollTop + e.currentTarget.offsetHeight) {
e.currentTarget.scrollTop -= 1;
}
scrolling = false;
}
});
// Prevents preventDefault from being called on document if it sees a scrollable div
$('body').on('touchmove','.scrollable',function(e) {
e.stopPropagation();
});
Also, adding the following CSS fixes some rendering glitches (source):
.scrollable {
overflow: auto;
overflow-x: hidden;
-webkit-overflow-scrolling: touch;
}
.scrollable * {
-webkit-transform: translate3d(0,0,0);
}
I will show visually the problem, using the great example from James answer and adding the alternative solution.
When you do the follow query, without the FETCH
:
Select e from Employee e
join e.phones p
where p.areaCode = '613'
You will have the follow results from Employee
as you expected:
EmployeeId | EmployeeName | PhoneId | PhoneAreaCode |
---|---|---|---|
1 | James | 5 | 613 |
1 | James | 6 | 416 |
But when you add the FETCH
word on JOIN
, this is what happens:
EmployeeId | EmployeeName | PhoneId | PhoneAreaCode |
---|---|---|---|
1 | James | 5 | 613 |
The generated SQL is the same for the two queries, but the Hibernate removes on memory the 416
register when you use WHERE
on the FETCH
join.
So, to bring all phones and apply the WHERE
correctly, you need to have two JOIN
s: one for the WHERE
and another for the FETCH
. Like:
Select e from Employee e
join e.phones p
join fetch e.phones //no alias, to not commit the mistake
where p.areaCode = '613'
swift 4 work as well as 3
libero.setTitle("---", for: .normal)
where libero is a uibutton
Get-ChildItem $originalPath\* -Include @("*.gif", "*.jpg", "*.xls*", "*.doc*", "*.pdf*", "*.wav*", "*.ppt")
the proper way is:
.attr({target:'nw', title:'Opens in a new window'})
Strings aren't value types since they can be huge, and need to be stored on the heap. Value types are (in all implementations of the CLR as of yet) stored on the stack. Stack allocating strings would break all sorts of things: the stack is only 1MB for 32-bit and 4MB for 64-bit, you'd have to box each string, incurring a copy penalty, you couldn't intern strings, and memory usage would balloon, etc...
(Edit: Added clarification about value type storage being an implementation detail, which leads to this situation where we have a type with value sematics not inheriting from System.ValueType. Thanks Ben.)
I'll not address the order of tests, sorry. Others already did it. Also, if you know about "ordered tests" - well, this is MS VS's response to the problem. I know that those ordered-tests are no fun. But they thought it will be "it" and there's really nothing more in MSTest about that.
I write about one of your assumptions:
as there is no way to tear down the static class.
Unless your static class represents some process-wide external state external to your code (like ie. the state of an unmanaged native DLL library thats P/Invoked by the rest of your code), your assumption that there is no way
is not true.
If your static class refers to this, then sorry, you are perfectly right, the rest of this anwer is irrelevant. Still, as you didn't say that, I assume your code is "managed".
Think and check the AppDomain
thingy. Rarely it is needed, but this is exactly the case when you'd probably like to use them.
You can create a new AppDomain, and instantiate the test there, and run the test method there. Static data used by managed code will isolated there and upon completion, you will be able to unload the AppDomain and all the data, statics included, will evaporate. Then, next test would initialize another appdomain, and so on.
This will work unless you have external state that you must track. AppDomains only isolate the managed memory. Any native DLL will still be load per-process and their state will be shared by all AppDomains.
Also, creating/tearing down the appdomains will, well, slow down the tests. Also, you may have problems with assembly resolution in the child appdomain, but they are solvable with reasonable amount of reusable code.
Also, you may have small problems with passing test data to - and back from - the child AppDomain. Objects passed will either have to be serializable in some way, or be MarshalByRef
or etc. Talking cross-domain is almost like IPC.
However, take care here, it will be 100% managed talking. If you take some extra care and add a little work to the AppDomain setup, you will be able to even pass delegates and run them in the target domain. Then, instead of making some hairy cross-domain setup, you can wrap your tests with to something like:
void testmethod()
{
TestAppDomainHelper.Run( () =>
{
// your test code
});
}
or even
[IsolatedAppDomain]
void testmethod()
{
// your test code
}
if your test framework supports creating such wrappers/extensions. After some initial research and work, using them is almost trivial.
if the project is not a big ,
1- change the name of folder project
2- make a new project with the same project (before renaming)
3- add existing files from the old project to the new project (totally same , same folders , same names , ...)
4- open the the new project file (as xml ) and the old project
5- copy the new project file (xml content ) and paste it in the old project file
6- delete the old project
7- rename the old folder project to old name
Ok, I found a working solution for this, it consists of using the beforeunload
event and then making the handler return null
. This executes the wanted code without a confirmation box popping-up. It goes something like this:
window.onbeforeunload = closingCode;
function closingCode(){
// do something...
return null;
}
If you're using 0
and an empty string ''
and null
to designate undefined you've got a data problem. Just update the columns and fix your schema.
UPDATE pt.incentive_channel
SET pt.incentive_marketing = NULL
WHERE pt.incentive_marketing = '';
UPDATE pt.incentive_channel
SET pt.incentive_advertising = NULL
WHERE pt.incentive_marketing = '';
UPDATE pt.incentive_channel
SET pt.incentive_channel = NULL
WHERE pt.incentive_marketing = '';
This will make joining and selecting substantially easier moving forward.
My solution will work if you apply the ActionFilter to the Subcategory action method, as long as you always want to redirect the user to the same bookmark:
http://spikehd.blogspot.com/2012/01/mvc3-redirect-action-to-html-bookmark.html
It modifies the HTML buffer and outputs a small piece of javascript to instruct the browser to append the bookmark.
You could modify the javascript to manually scroll, instead of using a bookmark in the URL, of course!
Hope it helps :)
well, I know that I'm a bit too late, but I tried all of your solutions and with no success!
So here is how I managed to do it.
First of all, I'm working on an Asp.Net MVC project.
The Only thing I changed was in my c# method getInvitation
:
public ActionResult getInvitation (Guid s_ID)
{
using (var db = new cRM_Verband_BWEntities())
{
var listSidsMit = (from data in db.TERMINEINLADUNGEN where data.RECID_KOMMUNIKATIONEN == s_ID select data.RECID_MITARBEITER.ToString()).ToArray();
return Json(listSidsMit);
}
}
SuccessFunction in JS :
function successFunction(result) {
console.log(result);
}
I changed the Method Type from string[]
to ActionResult
and of course at the end I wrapped my array listSidsMit
with the Json method.
By default git revert
refuses to revert a merge commit as what that actually means is ambiguous. I presume that your HEAD
is in fact a merge commit.
If you want to revert the merge commit, you have to specify which parent of the merge you want to consider to be the main trunk, i.e. what you want to revert to.
Often this will be parent number one, for example if you were on master
and did git merge unwanted
and then decided to revert the merge of unwanted
. The first parent would be your pre-merge master
branch and the second parent would be the tip of unwanted
.
In this case you could do:
git revert -m 1 HEAD
if you are using FragmentActivity
. then do like this
first call This inside your Fragment
.
public void callParentMethod(){
getActivity().onBackPressed();
}
and then Call onBackPressed
method in side your parent FragmentActivity
class.
@Override
public void onBackPressed() {
//super.onBackPressed();
//create a dialog to ask yes no question whether or not the user wants to exit
...
}
1st Figure out which user is owning httpd process using the following command
ps aux | grep httpd
you will get a several line response like this:
phpuser 17121 0.0 0.2 414060 7928 ? SN 03:49 0:00 /usr/sbin/httpd
Here 1st column shows the user name. So now you know the user who is trying to write files, which is in this case phpuser
You can now go ahead and set the permission for directory where your php script is trying to write something:
sudo chown phpuser:phpuser PhpCanWriteHere
sudo chmod 755 PhpCanWriteHere
Actually, valueOf
uses parseInt
internally. The difference is parseInt
returns an int
primitive while valueOf
returns an Integer
object. Consider from the Integer.class source:
public static int parseInt(String s) throws NumberFormatException {
return parseInt(s, 10);
}
public static Integer valueOf(String s, int radix) throws NumberFormatException {
return Integer.valueOf(parseInt(s, radix));
}
public static Integer valueOf(String s) throws NumberFormatException {
return Integer.valueOf(parseInt(s, 10));
}
As for parsing with a comma, I'm not familiar with one. I would sanitize them.
int million = Integer.parseInt("1,000,000".replace(",", ""));
There is an XML value alpha
that takes double values.
Since API 11+
the range is from 0f
to 1f
(inclusive), 0f
being transparent and 1f
being opaque:
android:alpha="0.0"
thats invisible
android:alpha="0.5"
see-through
android:alpha="1.0"
full visible
That's how it works.
I just opened the dump.sql file in Notepad++ and hit CTRL+H to find and replace the string "utf8mb4_0900_ai_ci" and replaced it with "utf8mb4_general_ci". Source link https://www.freakyjolly.com/resolved-when-i-faced-1273-unknown-collation-utf8mb4_0900_ai_ci-error/
Yet, it is possible to fake it using a dedicated table, named for your fake-sp, with an AFTER INSERT trigger. The dedicated table rows contain the parameters for your fake sp, and if it needs to return results you can have a second (poss. temp) table (with name related to the fake-sp) to contain those results. It would require two queries: first to INSERT data into the fake-sp-trigger-table, and the second to SELECT from the fake-sp-results-table, which could be empty, or have a message-field if something went wrong.
You can use chomp to merge multiple line in single line:
perl -e 'while (<>) { if (/\$/ ) { chomp; } print ;}' bad0 >test
put line break condition in if statement.It can be special character or any delimiter.
Save it as a .ps1 file and then execute
powershell -file "path\to your\start stop nation service command file.ps1"
I have also stuck with the same issue I have tried blow:
1.Try kill the process related to svn i.e. TSVNCache.exe and TortoiseProc 2.Reverting the unversioned files and deletion of same, which I have in svn . 3.cleanup using command prompt "svn cleanup"
and finally when restarted the desktop it worked for me , So for restart of system worked for me
In the recent go versions from 1.14 onwards, we have to do go mod vendor
before building or running, since by default go appends -mod=vendor
to the go commands.
So after doing go mod vendor
, if we try to build, we won't face this issue.
Based on kynan's answer, here are the same aliases, modified so they can handle spaces and initial dashes in filenames:
accept-ours = "!f() { [ -z \"$@\" ] && set - '.'; git checkout --ours -- \"$@\"; git add -u -- \"$@\"; }; f"
accept-theirs = "!f() { [ -z \"$@\" ] && set - '.'; git checkout --theirs -- \"$@\"; git add -u -- \"$@\"; }; f"
I'm writing an OpenCL 1.2 backend for Tensorflow at https://github.com/hughperkins/tensorflow-cl
This fork of tensorflow for OpenCL has the following characteristics:
This is not the only OpenCL fork of Tensorflow available. There is also a fork being developed by Codeplay https://www.codeplay.com , using Computecpp, https://www.codeplay.com/products/computesuite/computecpp Their fork has stronger requirements than my own, as far as I know, in terms of which specific GPU devices it works on. You would need to check the Platform Support Notes (at the bottom of hte computecpp page), to determine whether your device is supported. The codeplay fork is actually an official Google fork, which is here: https://github.com/benoitsteiner/tensorflow-opencl
A slightly out-of-the-box method would be to script up a solution in AutoHotKey. I use this, and it's not perfect, but works and is free. Essentially, this script assigns a hotkey to CTRL+SHIFT+R which will copy the selected SQL in SSMS (CTRL+C), save off a datestamp SQL file, and then execute the highlighted query (F5). If you aren't used to AHK scripts, the leading semicolon is a comment.
;CTRL+SHIFT+R to run a query that is first saved off
^+r::
;Copy
Send, ^c
; Set variables
EnvGet, HomeDir, USERPROFILE
FormatTime, DateString,,yyyyMMdd
FormatTime, TimeString,,hhmmss
; Make a spot to save the clipboard
FileCreateDir %HomeDir%\Documents\sqlhist\%DateString%
FileAppend, %Clipboard%, %HomeDir%\Documents\sqlhist\%DateString%\%TimeString%.sql
; execute the query
Send, {f5}
Return
The biggest limitations are that this script won't work if you click "Execute" rather than use the keyboard shortcut, and this script won't save off the whole file - just the selected text. But, you could always modify the script to execute the query, and then select all (CTRL+A) before the copy/save.
Using a modern editor with "find in files" features will let you search your SQL history. You could even get fancy and scrape your files into a SQLite3 database to query your queries.
By "camera position," it sounds like you want to adjust the elevation and the azimuth angle that you use to view the 3D plot. You can set this with ax.view_init
. I've used the below script to first create the plot, then I determined a good elevation, or elev
, from which to view my plot. I then adjusted the azimuth angle, or azim
, to vary the full 360deg around my plot, saving the figure at each instance (and noting which azimuth angle as I saved the plot). For a more complicated camera pan, you can adjust both the elevation and angle to achieve the desired effect.
from mpl_toolkits.mplot3d import Axes3D
ax = Axes3D(fig)
ax.scatter(xx,yy,zz, marker='o', s=20, c="goldenrod", alpha=0.6)
for ii in xrange(0,360,1):
ax.view_init(elev=10., azim=ii)
savefig("movie%d.png" % ii)
$query_string = "";
if ($_POST) {
$kv = array();
foreach ($_POST as $key => $value) {
$kv[] = stripslashes($key) . "=" . stripslashes($value);
}
$query_string = join("&", $kv);
}
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
$url = 'https://www.abcd.com/servlet/';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($kv));
curl_setopt($ch, CURLOPT_POSTFIELDS, $query_string);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
$result = curl_exec($ch);
curl_close($ch);
For me placing my fonts folder as per location specified in bootstrap.css solved the problem
Mostly its fonts folder should be in parent directory of bootstrap.css file .
I faced this problem , and researching many answers , if anyone still in 2015 faces this problem then its either a CSS problem , or location mismatch for files .
The bug has already been solved by bootstrap
"files" in *nix type systems are very much an abstract concept.
They can be areas on disk organized by a file system, but they could equally well be a network connection, a bit of shared memory, the buffer output from another process, a screen or a keyboard.
In order for perl to be really useful it mirrors this model very closely, and does not treat files by emulating a magnetic tape as many 4gls do.
So it tried an "IOCTL" operation 'open for write' on a file handle which does not allow write operations which is an inappropriate IOCTL operation for that device/file.
The easiest thing to do is stick an " or die 'Cannot open $myfile'
statement at the end of you open and you can choose your own meaningful message.
Try setting its position
to absolute. That takes it out of the flow of the document.
If you're willing to include the jQuery UI library, in addition to jQuery itself, then you can simply use hide()
, with additional arguments, as follows:
$(document).ready(
function(){
$('#slider').click(
function(){
$(this).hide('slide',{direction:'right'},1000);
});
});
Without using jQuery UI, you could achieve your aim just using animate()
:
$(document).ready(
function(){
$('#slider').click(
function(){
$(this)
.animate(
{
'margin-left':'1000px'
// to move it towards the right and, probably, off-screen.
},1000,
function(){
$(this).slideUp('fast');
// once it's finished moving to the right, just
// removes the the element from the display, you could use
// `remove()` instead, or whatever.
}
);
});
});
If you do choose to use jQuery UI, then I'd recommend linking to the Google-hosted code, at: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js
Here's a bit more complicated example with piping and variable assignment inside recipe:
getpodname:
# Getting pod name
@eval $$(minikube docker-env) ;\
$(eval PODNAME=$(shell sh -c "kubectl get pods | grep profile-posts-api | grep Running" | awk '{print $$1}'))
echo $(PODNAME)
Try these:
window.location.href = 'http://www.google.com';
window.location.assign("http://www.w3schools.com");
window.location = 'http://www.google.com';

Solution using Decorators that survives minification/uglification
We use code generation to decorate our Entity classes with metadata like so:
@name('Customer')
export class Customer {
public custId: string;
public name: string;
}
Then consume with the following helper:
export const nameKey = Symbol('name');
/**
* To perserve class name though mangling.
* @example
* @name('Customer')
* class Customer {}
* @param className
*/
export function name(className: string): ClassDecorator {
return (Reflect as any).metadata(nameKey, className);
}
/**
* @example
* const type = Customer;
* getName(type); // 'Customer'
* @param type
*/
export function getName(type: Function): string {
return (Reflect as any).getMetadata(nameKey, type);
}
/**
* @example
* const instance = new Customer();
* getInstanceName(instance); // 'Customer'
* @param instance
*/
export function getInstanceName(instance: Object): string {
return (Reflect as any).getMetadata(nameKey, instance.constructor);
}
Extra info:
reflect-metadata
reflect-metadata
is pollyfill written by members ot TypeScript for the proposed ES7 Reflection APIJust subscribe to the control's ToolTipTextNeeded event, and return e.TooltipText, much simpler.
This is different for each browser, in IE and windows you need to create what they call a pluggable protocol handler.
The basic steps are as follows:
See About Asynchronous Pluggable Protocols on MSDN for more details on the windows side. There is also a sample in the windows SDK.
A quick google also showed this article on codeproject: http://www.codeproject.com/KB/IP/DataProtocol.aspx.
Finally, as a security guy I have to point out that this code needs to be battle hardened. It's at a high risk because to do it reliably you can't do it in managed code and have to do it in C++ (I suppose you could use VB6). You should consider whether you really need to do this and if you do, design it carefully and code it securely. An attacker can easily control the content that gets passed to you by simply including a link on a page. For example if you have a simple buffer overflow then nobody better do this: <a href="custom:foooo{insert long string for buffer overflow here}"> Click me for free porn</a>
Strongly consider using strsafe and the new secure CRT methods included in the VC8 and above compilers. See http://blogs.msdn.com/michael_howard/archive/2006/02/27/540123.aspx if you have no idea what I'm talking about.
Sort of combined the first two answers, with a tweak to ironfroggy's code so that it returns a tuple:
import operator
class stuple(tuple):
def __add__(self, other):
return self.__class__(map(operator.add, self, other))
# obviously leaving out checking lengths
>>> a = stuple([1,2,3])
>>> b = stuple([3,2,1])
>>> a + b
(4, 4, 4)
Note: using self.__class__
instead of stuple
to ease subclassing.
With python3, iterate on dic.keys() will raise the dictionary size error. You can use this alternative way:
Tested with python3, it works fine and the Error "dictionary changed size during iteration" is not raised:
my_dic = { 1:10, 2:20, 3:30 }
# Is important here to cast because ".keys()" method returns a dict_keys object.
key_list = list( my_dic.keys() )
# Iterate on the list:
for k in key_list:
print(key_list)
print(my_dic)
del( my_dic[k] )
print( my_dic )
# {}
A cookie is a object with key value pair to store information related to the customer. Main objective is to personalize the customer's experience.
An utility method can be created like
private Cookie createCookie(String cookieName, String cookieValue) {
Cookie cookie = new Cookie(cookieName, cookieValue);
cookie.setPath("/");
cookie.setMaxAge(MAX_AGE_SECONDS);
cookie.setHttpOnly(true);
cookie.setSecure(true);
return cookie;
}
If storing important information then we should alsways put setHttpOnly so that the cookie cannot be accessed/modified via javascript. setSecure is applicable if you are want cookies to be accessed only over https protocol.
using above utility method you can add cookies to response as
Cookie cookie = createCookie("name","value");
response.addCookie(cookie);
If you have the stats toolbox, then you can compute
Z = zscore(S);
Aredridels answer is relatively good (upvoted it), but I think it lacks the loop equivalent. This should help you:
Sync code equivalent:
while (condition) {
var data = request(url);
<math here>
}
return result;
Async code for serial execution:
function continueLoop() {
if (!condition) return cb(result);
request(url, function(err, res, body) {
<math here>
continueLoop()
})
}
continueLoop()
After all the Jquery script tag's add
<script>jQuery.noConflict();</script>
to avoid the conflict between Prototype and Jquery.
The best way is to create a virtual env. first and then do pip install , everything will work fine
You can do a form.serializeArray(), then add name-value pairs before posting:
var form = $(this).closest('form');
form = form.serializeArray();
form = form.concat([
{name: "customer_id", value: window.username},
{name: "post_action", value: "Update Information"}
]);
$.post('/change-user-details', form, function(d) {
if (d.error) {
alert("There was a problem updating your user details")
}
});
You should have grep
like this:
$ grep 'string1' file | grep 'string2'
Try stringWithFormat:
NSString *myString = [NSString stringWithFormat:@"%@ %@ %@ %d", "The", "Answer", "Is", 42];
public static class GlobalVariables
{
// readonly variable
public static string Foo
{
get
{
return "foo";
}
}
// read-write variable
public static string Bar
{
get
{
return HttpContext.Current.Application["Bar"] as string;
}
set
{
HttpContext.Current.Application["Bar"] = value;
}
}
}
In my fairly complex scenario the accepted answer for how to do this in Chrome doesn't work for me. You may want to try the Firefox debugger instead (part of the Firefox developer tools), which shows all of the 'Sources', including those that are part of an iFrame
You can add your receipients to $email_to
variable separating them with comma (,
). Or you can add new fields to headers, namely CC:
or BCC:
and put your receipients there. BCC
is most recommended
The server_name
docs directive is used to identify virtual hosts, they're not used to set the binding.
netstat
tells you that nginx listens on 0.0.0.0:80
which means that it will accept connections from any IP.
If you want to change the IP nginx binds on, you have to change the listen
docs rule.
So, if you want to set nginx to bind to localhost
, you'd change that to:
listen 127.0.0.1:80;
In this way, requests that are not coming from localhost are discarded (they don't even hit nginx).
It's best if you worked with DataSet
s and/or DataTable
s. Once you have that, ideally straight from your stored procedure with proper column names for headers, you can use the following method:
ws.Cells.LoadFromDataTable(<DATATABLE HERE>, true, OfficeOpenXml.Table.TableStyles.Light8);
.. which will produce a beautiful excelsheet with a nice table!
Now to serve your file, assuming you have an ExcelPackage
object as in your code above called pck
..
Response.Clear();
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("Content-Disposition", "attachment;filename=" + sFilename);
Response.BinaryWrite(pck.GetAsByteArray());
Response.End();
HTML Table row heights will typically change proportionally to the table height, if the table height is larger than the height of your rows. Since the table is forcing the height of your rows, you can remove the table height to resolve the issue. If this is not acceptable, you can also give the rows explicit height, and add a third row that will auto size to the remaining table height.
Another option in CSS2 is the Max-Height Property, although it may lead to strange behavior in a table.http://www.w3schools.com/cssref/pr_dim_max-height.asp
.
if(resp) {
try {
resp = $.parseJSON(resp);
console.log(resp);
} catch(e) {
alert(e);
}
}
hope this works for you too
Just add android:background="@android:color/transparent"
like below in your appbar layout
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/transparent">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>`
I'll just post the code to do this using the fluent API mapping.
public class User {
public int UserID { get; set; }
public string Username { get; set; }
public string Password { get; set; }
public ICollection<UserEmail> UserEmails { get; set; }
}
public class Email {
public int EmailID { get; set; }
public string Address { get; set; }
public ICollection<UserEmail> UserEmails { get; set; }
}
public class UserEmail {
public int UserID { get; set; }
public int EmailID { get; set; }
public bool IsPrimary { get; set; }
}
On your DbContext
derived class you could do this:
public class MyContext : DbContext {
protected override void OnModelCreating(DbModelBuilder builder) {
// Primary keys
builder.Entity<User>().HasKey(q => q.UserID);
builder.Entity<Email>().HasKey(q => q.EmailID);
builder.Entity<UserEmail>().HasKey(q =>
new {
q.UserID, q.EmailID

It has the same effect as the accepted answer, with a different approach, which is no better nor worse.
A memory heap is a location in memory where memory may be allocated at random access.
Unlike the stack where memory is allocated and released in a very defined order, individual data elements allocated on the heap are typically released in ways which is asynchronous from one another. Any such data element is freed when the program explicitly releases the corresponding pointer, and this may result in a fragmented heap. In opposition only data at the top (or the bottom, depending on the way the stack works) may be released, resulting in data element being freed in the reverse order they were allocated.
The question was :
Is there a fast way of getting all COLUMN NAMES from all tables in MySQL, without having to list all the tables?
SQL to get all information for each column
select * from information_schema.columns
where table_schema = 'your_db'
order by table_name,ordinal_position
SQL to get all COLUMN NAMES
select COLUMN_NAME from information_schema.columns
where table_schema = 'your_db'
order by table_name,ordinal_position
For SQL Server 2016+ and Azure SQL Database, the STRING_SPLIT function was added that would be a perfect solution for this problem. Here is the documentation: https://docs.microsoft.com/en-us/sql/t-sql/functions/string-split-transact-sql
Here is an example:
/*List of ids in a comma delimited string
Note: the ') WAITFOR DELAY ''00:00:02''' is a way to verify that your script
doesn't allow for SQL injection*/
DECLARE @listOfIds VARCHAR(MAX) = '1,3,a,10.1,) WAITFOR DELAY ''00:00:02''';
--Make sure the temp table was dropped before trying to create it
IF OBJECT_ID('tempdb..#MyTable') IS NOT NULL DROP TABLE #MyTable;
--Create example reference table
CREATE TABLE #MyTable
([Id] INT NOT NULL);
--Populate the reference table
DECLARE @i INT = 1;
WHILE(@i <= 10)
BEGIN
INSERT INTO #MyTable
SELECT @i;
SET @i = @i + 1;
END
/*Find all the values
Note: I silently ignore the values that are not integers*/
SELECT t.[Id]
FROM #MyTable as t
INNER JOIN
(SELECT value as [Id]
FROM STRING_SPLIT(@listOfIds, ',')
WHERE ISNUMERIC(value) = 1 /*Make sure it is numeric*/
AND ROUND(value,0) = value /*Make sure it is an integer*/) as ids
ON t.[Id] = ids.[Id];
--Clean-up
DROP TABLE #MyTable;
The result of the query is 1,3

There should be some error in resource files. It mean is there may be miss typed value of attributes. Go through the resource files and correct these value and enjoy the work.
If it has been staged and committed, then the following will reset the file:
git reset COMMIT_HASH file_path
git checkout COMMIT_HASH file_path
git add file_path
This will work for a deletion that occurred several commits previous.
I done it, below code is working for me....
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.hello_world, container, false);
Button newPage = (Button)v.findViewById(R.id.click);
newPage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getActivity(), HomeActivity.class);
startActivity(intent);
}
});
return v;
}
and Please make sure that your destination activity should be register in Manifest.xml file,
but in my case all tabs are not shown in HomeActivity, is any solution for that ?
Here's my shell script solution, which deletes derived data and cleans a project's cached assets, for Xcode 4, 5 and 6.
Sometimes, simply calling rm -rf on the Derived Data directory leaves a lingering file or two, but my script loops until all files are deleted.
CMake is actually pretty good for this. The key part was everyone on the Windows side has to remember to run CMake before loading in the solution, and everyone on our Mac side would have to remember to run it before make.
The hardest part was as a Windows developer making sure your structural changes were in the cmakelist.txt file and not in the solution or project files as those changes would probably get lost and even if not lost would not get transferred over to the Mac side who also needed them, and the Mac guys would need to remember not to modify the make file for the same reasons.
It just requires a little thought and patience, but there will be mistakes at first. But if you are using continuous integration on both sides then these will get shook out early, and people will eventually get in the habit.
If you are centering the output of an R code chunk, e.g., a plot, then you can use the fig.align
option in knitr.
```{r fig.align="center"}
plot(mtcars)
```
SELECT SUM(Output.count),Output.attr
FROM
(
SELECT COUNT(column1 ) AS count,column1 AS attr FROM tab1 GROUP BY column1
UNION ALL
SELECT COUNT(column2) AS count,column2 AS attr FROM tab1 GROUP BY column2
UNION ALL
SELECT COUNT(column3) AS count,column3 AS attr FROM tab1 GROUP BY column3) AS Output
GROUP BY attr
I would recommend to use Bootstrap. http://getbootstrap.com/. This approach is very straight-forward and light weight.
<div class="navbar navbar-inverse navbar-fixed-top">
<div class="container">
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav navbar-fixed-top">
<li><a href="#home"> <br>BLINK</a></li>
<li><a href="#news"><br>ADVERTISING WITH BLINK</a></li>
<li><a href="#contact"><br>EDUCATING WITH BLINK</a></li>
<li><a href="#about"><br>ABOUT US</a></li>
</ul>
</div>
</div>
</div>
You need to include the Bootstrap into your project, which will include the necessary scripts and styles. Then just call the class 'navbar-fixed-top'. This will do the trick. See above example
The response data are in JSON string form. The app must parse that string into JavaScript objects by calling response.json().
this.http.request('http://thecatapi.com/api/images/get?format=html&results_per_page=10').
.map(res => res.json())
.subscribe(data => {
console.log(data);
})
https://angular.io/docs/ts/latest/guide/server-communication.html#!#extract-data
<?php
// run query
$query = mysql_query("SELECT * FROM table");
// set array
$array = array();
// look through query
while($row = mysql_fetch_assoc($query)){
// add each row returned into an array
$array[] = $row;
// OR just echo the data:
echo $row['username']; // etc
}
// debug:
print_r($array); // show all array data
echo $array[0]['username']; // print the first rows username
For another as Latin languages for example Cyrillic you can use something like this:
FileReader fr = new FileReader("src/text.txt", StandardCharsets.UTF_8);
and be sure that your .txt
file is saved with UTF-8
(but not as default ANSI
) format. Cheers!
If you want to see the difference as just the names of the files changed then use:
git diff --name-status <remote-branch> <local-branch>
,
else this would show all differences between the two branches:
git diff <remote-branch> <local-branch>
Add this to the stylesheet:
table {
border-collapse: collapse;
}
The reason why it behaves this way is actually described pretty well in the specification:
There are two distinct models for setting borders on table cells in CSS. One is most suitable for so-called separated borders around individual cells, the other is suitable for borders that are continuous from one end of the table to the other.
... and later, for collapse
setting:
In the collapsing border model, it is possible to specify borders that surround all or part of a cell, row, row group, column, and column group.
How about?
<?php
$queried_post = get_page_by_path('my_slug',OBJECT,'post');
?>
I think that the easiest solution is to use Apache Common Codec:
String sha256hex = org.apache.commons.codec.digest.DigestUtils.sha256Hex(stringText);
in Laravel 5.4
use this method:
Session::put('variableName', $value);
After your databind:
drpList.Items.Insert(0, new ListItem(String.Empty, String.Empty));
drpList.SelectedIndex = 0;
Honestly, I'd recommend using phpseclib, a pure PHP SSH2 implementation. Example:
<?php
include('Net/SSH2.php');
$ssh = new Net_SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
exit('Login Failed');
}
echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>
It's a ton more portable, easier to use and more feature packed too.
If you use XCode
5 you should do it in a different way.
UIViewController
in UIStoryboard
Identity Inspector
on the right top paneUse Storyboard ID
checkboxStoryboard ID
fieldThen write your code.
// Override point for customization after application launch.
if (<your implementation>) {
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main"
bundle: nil];
YourViewController *yourController = (YourViewController *)[mainStoryboard
instantiateViewControllerWithIdentifier:@"YourViewControllerID"];
self.window.rootViewController = yourController;
}
return YES;
It looks like you are not providing a value for the primary key field DB_ID. If that is a primary key, you must provide a unique value for that column. The only way not to provide it would be to create a database trigger that, on insert, would provide a value, most likely derived from a sequence.
If this is a restoration from another database and there is a sequence on this new instance, it might be trying to reuse a value. If the old data had unique keys from 1 - 1000 and your current sequence is at 500, it would be generating values that already exist. If a sequence does exist for this table and it is trying to use it, you would need to reconcile the values in your table with the current value of the sequence.
You can use SEQUENCE_NAME.CURRVAL to see the current value of the sequence (if it exists of course)

System.out.print(' ');
for (j = 0; j < y * 2 + 1; j++)
// number of '*' each row

System.out.println();

The problem was caused by missing inclusion of ngRoute module. Since version 1.1.6 it's a separate part:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>
var app = angular.module('myapp', ['ngRoute']);

Here is a lazy hack from: http://odedhb.blogspot.com/2013/05/android-layout-shadow-without-9-patch.html
(toast_frame does not work on KitKat, shadow was removed from toasts)
just use:
android:background="@android:drawable/toast_frame"
or:
android:background="@android:drawable/dialog_frame"
as a background
examples:
<TextView
android:layout_width="fill_parent"
android:text="I am a simple textview with a shadow"
android:layout_height="wrap_content"
android:textSize="18sp"
android:padding="16dp"
android:textColor="#fff"
android:background="@android:drawable/toast_frame"
/>
and with different bg color:
<LinearLayout
android:layout_height="64dp"
android:layout_width="fill_parent"
android:gravity="center"
android:background="@android:drawable/toast_frame"
android:padding="4dp"

JSONP is a way of getting around the browser's same-origin policy. How? Like this:
The goal here is to make a request to otherdomain.com
and alert
the name in the response. Normally we'd make an AJAX request:
$.get('otherdomain.com', function (response) {
var name = response.name;
alert(name);
});
However, since the request is going out to a different domain, it won't work.
We can make the request using a <script>
tag though. Both <script src="otherdomain.com"></script>
and $.get('otherdomain.com')
will result in the same request being made:
GET otherdomain.com
Q: But if we use the <script>
tag, how could we access the response? We need to access it if we want to alert
it.
A: Uh, we can't. But here's what we could do - define a function that uses the response, and then tell the server to respond with JavaScript that calls our function with the response as its argument.
Q: But what if the server won't do this for us, and is only willing to return JSON to us?
A: Then we won't be able to use it. JSONP requires the server to cooperate.
Q: Having to use a <script>
tag is ugly.
A: Libraries like jQuery make it nicer. Ex:
$.ajax({
url: "http://otherdomain.com",
jsonp: "callback",
dataType: "jsonp",
success: function( response ) {
console.log( response );
}
});
It works by dynamically creating the <script>
tag DOM element.
Q: <script>
tags only make GET requests - what if we want to make a POST request?
A: Then JSONP won't work for us.
Q: That's ok, I just want to make a GET request. JSONP is awesome and I'm going to go use it - thanks!
A: Actually, it isn't that awesome. It's really just a hack. And it isn't the safest thing to use. Now that CORS is available, you should use it whenever possible.
You can do it through the tabpages: tabPage1.Hide(), tabPage2.Show() etc.
See the wiki article:
In point-to-point situations confidentiality and data integrity can also be enforced on Web services through the use of Transport Layer Security (TLS), for example, by sending messages over https.
WS-Security however addresses the wider problem of maintaining integrity and confidentiality of messages until after a message was sent from the originating node, providing so called end to end security.
That is:
Unfortunately, the best thing I have seen is the jquery.combobox, but it doesn't really look like something I'd really want to use in my web applications. I think there are some usability issues with this control, but as a user I don't think I'd know to start typing for the dropdownlist to turn into a textbox.
I much prefer the Combo Dropdown Box, but it still has some features that I'd want and it's still in alpha. The only think I don't like about this other than its being alpha... is that once I type in the combobox, the original dropdownlist items disappear. However, maybe there is a setting for this... or maybe it could be added fairly easily.
Those are the only two options that I know of. Good luck in your search. I'd love to hear if you find one or if the second option works out for you.
With SimpleDateFormat
. And steps are -
SimpleDateFormat
ObjectDate
Object.This topic is quite old, but here is a handy solution that I found:
http://www.cityinthesky.co.uk/opensource/pdf2svg/
It offers a tool, pdf2png, which once installed does exactly the job in command line. I've tested it with irreproachable results so far, including with bitmaps.
EDIT : My mistake, this tool also converts letters to paths, so it does not address the initial question. However it does a good job anyway, and can be useful to anyone who does not intend to modify the code in the svg file, so I'll leave the post.
The only escape sequence you can use in single quotes is for the single quote itself.
$foo = 'That\'s great';
The only way you could insert a new line into a string created with single quotes is to insert a literal newline
$bar = 'That\'s
cheating';
I encourage you to read the Maven Book about multi-module (reactor) builds.
I meant in particular the following:
<parent>
<artifactId>xyz-application</artifactId>
<groupId>com.xyz</groupId>
<version>2.50.0.g</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<groupId>com.xyz</groupId>
<artifactId>xyz-Library</artifactId>
<version>2.50.0.g</version>
should be changed into. Here take care about the not defined version only in parent part it is defined.
<modelVersion>4.0.0</modelVersion>
<parent>
<artifactId>xyz-application</artifactId>
<groupId>com.xyz</groupId>
<version>2.50.0.g</version>
</parent>
<groupId>com.xyz</groupId>
<artifactId>xyz-Library</artifactId>
This is a better link.
you also should specify def name in the project settings here:
Configuration > Properties/Input/Advanced/Module > Definition File
Accepted answer is correct, but if you want to avoid entering the password interactively, you can use this:

This does not answer your specific question, but when I had the same problem I ended up here and I figured that more people might do the same.
The problem I had was that I had indeliberately declared my Get method as static. I missed this an entire forenoon, and it caused no warnings from attributes or similar.
Incorrect:
public class EchoController : ApiController
{
public static string Get()
{
return string.Empty;
}
}
Correct:
public class EchoController : ApiController
{
public string Get()
{
return string.Empty;
}
}
For one-level flatten, if you care about speed, this is faster than any of the previous answers under all conditions I tried. (That is, if you need the result as a list. If you only need to iterate through it on the fly then the chain example is probably better.) It works by pre-allocating a list of the final size and copying the parts in by slice (which is a lower-level block copy than any of the iterator methods):
def join(a):
"""Joins a sequence of sequences into a single sequence. (One-level flattening.)
E.g., join([(1,2,3), [4, 5], [6, (7, 8, 9), 10]]) = [1,2,3,4,5,6,(7,8,9),10]
This is very efficient, especially when the subsequences are long.
"""
n = sum([len(b) for b in a])
l = [None]*n
i = 0
for b in a:
j = i+len(b)
l[i:j] = b
i = j
return l
Sorted times list with comments:
[(0.5391559600830078, 'flatten4b'), # join() above.
(0.5400412082672119, 'flatten4c'), # Same, with sum(len(b) for b in a)
(0.5419249534606934, 'flatten4a'), # Similar, using zip()
(0.7351131439208984, 'flatten1b'), # list(itertools.chain.from_iterable(a))
(0.7472689151763916, 'flatten1'), # list(itertools.chain(*a))
(1.5468521118164062, 'flatten3'), # [i for j in a for i in j]
(26.696547985076904, 'flatten2')] # sum(a, [])
It depends on your OS, but 2147483647 is the usual value, according to the manual.
Note that if strings has spaces then quotation marks are needed at definition and must be chopped while concatenating:

You could just define a new xml background in the drawables folder
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="enter_your_desired_color_here" />
<corners android:radius="enter_your_desired_radius_the_corners" />
</shape>
After this just include it in your TextView or EditText by defining it in the background.
<TextView
android:id="@+id/textView"
android:layout_width="0dp"
android:layout_height="80dp"
android:background="YOUR_FILE_HERE"
Android:layout_weight="1"
android:gravity="center"
android:text="TEXT_HERE"
android:textSize="40sp" />
When you call startActivity
on the last activity you could always use
Intent.FLAG_ACTIVITY_CLEAR_TOP
as a flag on that intent.

You're trying to write more data than a specific column can store. Check the sizes of the data you're trying to insert against the sizes of each of the fields.
In this case transaction_status is a varchar(10) and you're trying to store 19 characters to it.
Javascript doesn't have it, as you point out.

// * returns 2: -1
return ( ( str1 == str2 ) ? 0 : ( ( str1 > str2 ) ? 1 : -1 ) );
}
from http://kevin.vanzonneveld.net/techblog/article/javascript_equivalent_for_phps_strcmp/
Of course, you could just add localeCompare if needed:
if (typeof(String.prototype.localeCompare) === 'undefined') {
String.prototype.localeCompare = function(str, locale, options) {
return ((this == str) ? 0 : ((this > str) ? 1 : -1));
};
}
And use str1.localeCompare(str2)
everywhere, without having to worry wether the local browser has shipped with it. The only problem is that you would have to add support for locales
and options
if you care about that.
You can access your session variable like '<%= Session["VariableName"]%>'
the text in single quotes will give session value. 1)
<script>
var session ='<%= Session["VariableName"]%>'
</script>
2) you can take a hidden field and assign value at server;
hiddenfield.value= session["xyz"].tostring();
//and in script you access the hiddenfield like
alert(document.getElementbyId("hiddenfield").value);
Use GetParent()
as shown, works nicely. Add error checking as you need.
var fn = openFileDialogSapTable.FileName;
var currentPath = Path.GetFullPath( fn );
currentPath = Directory.GetParent(currentPath).FullName;

In my case, it was caused by my Unicode file being saved with a "BOM". To solve this, I cracked open the file using BBEdit and did a "Save as..." choosing for encoding "Unicode (UTF-8)" and not what it came with which was "Unicode (UTF-8, with BOM)"
My answer is not about static parent-child layout, its about animations.
I was doing an svg demo today, and i needed svg to be inside div (because svg is created with parent's div width and height, to animate the path around), and this parent div needed to be invisible during svg path animation (and then this div was supposed to animate opacity from 0 to 1
, it's the most important part). And because parent div with opacity: 0
was hiding my svg, i came across this hack with visibility
option (child with visibility: visible
can be seen inside parent with visibility: hidden
):
.main.invisible .test {
visibility: hidden;
}
.main.opacity-zero .test {
opacity: 0;
transition: opacity 0s !important;
}
.test { // parent div
transition: opacity 1s;
}
.test-svg { // child svg
visibility: visible;
}
And then, in js, you removing .invisible
class with timeout function, adding .opacity-zero
class, trigger layout with something like whatever.style.top;
and removing .opacity-zero
class.
var $main = $(".main");
setTimeout(function() {
$main.addClass('opacity-zero').removeClass("invisible");
$(".test-svg").hide();
$main.css("top");
$main.removeClass("opacity-zero");
}, 3000);

As Dhruv Gairola answered, you can save the state of the application by using Bundle savedInstanceState. I am trying to give a very simple example that new learners like me can understand easily.
Suppose, you have a simple fragment with a TextView and a Button. Each time you clicked the button the text changes. Now, change the orientation of you device/emulator and notice that you lost the data (means the changed data after clicking you got) and fragment starts as the first time again. By using Bundle savedInstanceState we can get rid of this. If you take a look into the life cyle of the fragment.Fragment Lifecylce you will get that a method "onSaveInstanceState" is called when the fragment is about to destroyed.
So, we can save the state means the changed text value into that bundle like this
int counter = 0;
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("value",counter);
}
After you make the orientation the "onCreate" method will be called right? so we can just do this
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(savedInstanceState == null){
//it is the first time the fragment is being called
counter = 0;
}else{
//not the first time so we will check SavedInstanceState bundle
counter = savedInstanceState.getInt("value",0); //here zero is the default value
}
}
Now, you won't lose your value after the orientation. The modified value always will be displayed.
Use a for
loop instead of .forEach()
var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false
for(var call of myObj) {
console.log(call)
var a = call['a'], b = call['b']
if(a == null || b == null) {
result = false
break
}
}
private void btnchangerate_Click(object sender, EventArgs e)
{
this.Hide(); //current form will hide
Form1 fm = new Form1(); //another form will open
fm.Show();
}
on click btn current form will hide and new form will open
officially, headers are case insensitive, however, it is common practice to capitalize the first letter of every word.
but, because it is common practice, certain programs like IE assume the headers are capitalized.
so while the docs say the are case insensitive, bad programmers have basically changed the docs.
I modified the code of Nikola Milicevic a little bit so it also remove comment block if code is already commented:

set input to replaceText("/*", "", input as string)
set input to replaceText("*/", "", input as string)
return input
exit repeat
end if
end repeat
return "/*" & (input as string) & "*/"
end run
on replaceText(find, replace, textString)
set prevTIDs to AppleScript's text item delimiters
set AppleScript's text item delimiters to find
set textString to text items of textString
set AppleScript's text item delimiters to replace
set textString to "" & textString
set AppleScript's text item delimiters to prevTIDs
return textString

The answer to your question is that the newer SQLite 3 has improved performance, use that.
This answer Why is SQLAlchemy insert with sqlite 25 times slower than using sqlite3 directly? by SqlAlchemy Orm Author has 100k inserts in 0.5 sec, and I have seen similar results with python-sqlite and SqlAlchemy. Which leads me to believe that performance has improved with SQLite 3.
As mentioned by @john, the most robust answer is:
string = "a\nb\rv"
new_string = " ".join(string.splitlines())
If you want to pass a Uri to another activity, try the method intent.setData(Uri uri) https://developer.android.com/reference/android/content/Intent.html#setData(android.net.Uri)
In another activity, via intent.getData() to obtain the Uri.

PowerShell Community Extensions (PSCX) provides the Get-FileTail
cmdlet. It looks like a suitable solution for the task. Note: I did not try it with extremely large files but the description says it efficiently tails the contents and it is designed for large log files.
NAME
Get-FileTail
SYNOPSIS
PSCX Cmdlet: Tails the contents of a file - optionally waiting on new content.
SYNTAX
Get-FileTail [-Path] <String[]> [-Count <Int32>] [-Encoding <EncodingParameter>] [-LineTerminator <String>] [-Wait] [<CommonParameters>]
Get-FileTail [-LiteralPath] <String[]> [-Count <Int32>] [-Encoding <EncodingParameter>] [-LineTerminator <String>] [-Wait] [<CommonParameters>]
DESCRIPTION
This implentation efficiently tails the cotents of a file by reading lines from the end rather then processing the entire file. This behavior is crucial for ef
ficiently tailing large log files and large log files over a network. You can also specify the Wait parameter to have the cmdlet wait and display new content
as it is written to the file. Use Ctrl+C to break out of the wait loop. Note that if an encoding is not specified, the cmdlet will attempt to auto-detect the
encoding by reading the first character from the file. If no character haven't been written to the file yet, the cmdlet will default to using Unicode encoding
. You can override this behavior by explicitly specifying the encoding via the Encoding parameter.
It is used to influence sorting in the CSS cascade when sorting by origin is done. It has nothing to do with specificity like stated here in other answers.
Here is the priority from lowest to highest:
After that specificity takes place for the rules still having a finger in the pie.
References:
If you want multiple messages from a queue, say 10 messages, the command to use is:
rabbitmqadmin get queue=<QueueName> ackmode=ack_requeue_true count=10
If you don't want the messages requeued, just change ackmode
to ack_requeue_false
.
preg_replace
offers one way:
$newText = preg_replace('/\bBy.*$/', '', $text);
In the specific case of the code example from the original question, the
System.out.print("\n");
is there to move to a new line between incrementing i.
So the first print statement prints all of the elements of Grid[0][j]. When the innermost for loop has completed, the "\n" gets printed and then all of the elements of Grid[1][j] are printed on the next line, and this is repeated until you have a 10x10 grid of the elements of the 2-dimensional array, Grid.
here is more simple way without StartCoroutine:
float t = 0f;
float waittime = 1f;
and inside Update/FixedUpdate:
if (t < 0){
t += Time.deltaTIme / waittime;
yield return t;
}
sesssionStorage.setObj(1,{date:Date.now(),action:'save firstObject'});
sesssionStorage.setObj(2,{date:Date.now(),action:'save 2nd object'});
//Query first object
sesssionStorage.getObj(1)
//Retrieve date created of 2nd object
new Date(sesssionStorage.getObj(1).date)
Storage.prototype.setObj = function(key, obj) {
return this.setItem(key, JSON.stringify(obj))
};
Storage.prototype.getObj = function(key) {
return JSON.parse(this.getItem(key))
};
You can use another overload of the DropDownList
method. Pick the one you need and pass in
a object with your html attributes.
@Html.DropDownList("CategoryID", null, new { @onchange="location = this.value;" })
Many other answers only do formatting. This approach will return value instead of only print format.
double number1 = 10.123456;
double number2 = (int)(Math.round(number1 * 100))/100.0;
System.out.println(number2);
Use the indent
argument of the dumps
function in the json module.
From the docs:
>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
"4": 5,
"6": 7
}
First try this: dont use the php composer.phar [parameters]
simply use composer [parameters]
if this doesn't work for you than try the rest. Hope it helps.
It's pretty simple. Pay attention and you'll get it right away! :)
You will create a html array, which will be then sent to php array. Your html code will look like this:
<input type="checkbox" name="check_list[1]" alt="Checkbox" value="checked">
<input type="checkbox" name="check_list[2]" alt="Checkbox" value="checked">
<input type="checkbox" name="check_list[3]" alt="Checkbox" value="checked">
Where [1] [2] [3]
are the ID
s of your messages, meaning that you will echo
your $row['Report ID']
in their place.
Then, when you submit the form, your PHP array will look like this:
print_r($check_list)
[1] => checked
[3] => checked
Depending on which were checked and which were not.
I'm sure you can continue from this point forward.
This is actually a bug in the tutorials code. I was having the same issue and I finally realized the issue was in the "note_edit.xml" file.
Some of the layout_heigh/width attributes were set to "match_parent" which is not a valid value, they're supposed to be set to "fill_parent".
This was throwing a bug, that was causing the generation of the R.java file to fail. So, if you're having this issue, or a similar one, check all of your xml files and make sure that none of them have any errors.

I have got the JDK installed
You haven't specified the version. I think it is not 6 nor 5.
JDK 6 was the latest version at time of NetBeans 6.0 - 6.9 are developed. For that reason, They require JDK 6 (or JDK 5) and do not run on JDK 7 or later.
A simple way of generating a printable report from a Datagridview is to place the datagridview on a Panel object. It is possible to draw a bitmap of the panel.
Here's how I do it.
'create the bitmap with the dimentions of the Panel Dim bmp As New Bitmap(Panel1.Width, Panel1.Height)
'draw the Panel to the bitmap "bmp" Panel1.DrawToBitmap(bmp, Panel1.ClientRectangle)
I create a multi page tiff by "breaking my datagridview items into pages. this is how i detect the start of a new page:
'i add the rows to my datagrid one at a time and then check if the scrollbar is active. 'if the scrollbar is active i save the row to a variable and then i remove it from the 'datagridview and roll back my counter integer by one(thus the next run will include this 'row.
Private Function VScrollBarVisible() As Boolean
Dim ctrl As New Control
For Each ctrl In DataGridView_Results.Controls
If ctrl.GetType() Is GetType(VScrollBar) Then
If ctrl.Visible = True Then
Return True
Else
Return False
End If
End If
Next
Return Nothing
End Function
I hope this helps
If a variable is defined as public static it can be accessed via its class name from any class.
Usually functions are defined as public static which can be accessed just by calling the implementing class name.
A very good example of it is the sleep()
method in Thread class
Thread.sleep(2500);
If a variable is defined as private static it can be accessed only within that class so no class name is needed or you can still use the class name (upto you). The difference between private var_name and private static var_name is that private static variables can be accessed only by static methods of the class while private variables can be accessed by any method of that class(except static methods)
A very good example of it is while defining database connections or constants which require declaring variable as private static .
Another common example is
private static int numberOfCars=10;
public static int returnNumber(){
return numberOfCars;
}
Use
getActivity().getApplicationContext()
to obtain the context in any fragment
Yes, the performance difference is significant. See the KB article "How to improve string concatenation performance in Visual C#".
I have always tried to code for clarity first, and then optimize for performance later. That's much easier than doing it the other way around! However, having seen the enormous performance difference in my applications between the two, I now think about it a little more carefully.
Luckily, it's relatively straightforward to run performance analysis on your code to see where you're spending the time, and then to modify it to use StringBuilder
where needed.
On iOS 11 please remember to add the following, if you're interested in creating a scrollview that sticks to the screen bounds rather than a safe area.:
if (@available(iOS 11.0, *)) {
[self.scrollView setContentInsetAdjustmentBehavior:UIScrollViewContentInsetAdjustmentNever];
}
from time import time
>>> int(time())
1542449530
>>> time()
1542449527.6991141
>>> int(time())
1542449530
>>> str(time()).replace(".","")
'154244967282'
But Should it not return ?
'15424495276991141'
it means ONLY one byte will be allocated per character - so if you're using multi-byte charsets, your 1 character won't fit
if you know you have to have at least room enough for 1 character, don't use the BYTE syntax unless you know exactly how much room you'll need to store that byte
when in doubt, use VARCHAR2(1 CHAR)
same thing answered here Difference between BYTE and CHAR in column datatypes
Also, in 12c the max for varchar2 is now 32k, not 4000. If you need more than that, use CLOB
in Oracle, don't use VARCHAR
This is for dynamic # of weeks.
Full example here:SQL Dynamic Pivot
DECLARE @DynamicPivotQuery AS NVARCHAR(MAX)
DECLARE @ColumnName AS NVARCHAR(MAX)
--Get distinct values of the PIVOT Column
SELECT @ColumnName= ISNULL(@ColumnName + ',','') + QUOTENAME(Week)
FROM (SELECT DISTINCT Week FROM #StoreSales) AS Weeks
--Prepare the PIVOT query using the dynamic
SET @DynamicPivotQuery =
N'SELECT Store, ' + @ColumnName + '
FROM #StoreSales
PIVOT(SUM(xCount)
FOR Week IN (' + @ColumnName + ')) AS PVTTable'
--Execute the Dynamic Pivot Query
EXEC sp_executesql @DynamicPivotQuery
If you are using Spring4/SpringBoot 1.x, then it's worth mentioning that you can add "text" (json) parts as well . This can be done via MockMvcRequestBuilders.fileUpload().file(MockMultipartFile file) (which is needed as method .multipart()
is not available in this version):
@Test
public void test() throws Exception {
mockMvc.perform(
MockMvcRequestBuilders.fileUpload("/files")
// file-part
.file(makeMultipartFile( "file-part" "some/path/to/file.bin", "application/octet-stream"))
// text part
.file(makeMultipartTextPart("json-part", "{ \"foo\" : \"bar\" }", "application/json"))
.andExpect(status().isOk())));
}
private MockMultipartFile(String requestPartName, String filename,
String contentType, String pathOnClassPath) {
return new MockMultipartFile(requestPartName, filename,
contentType, readResourceFile(pathOnClasspath);
}
// make text-part using MockMultipartFile
private MockMultipartFile makeMultipartTextPart(String requestPartName,
String value, String contentType) throws Exception {
return new MockMultipartFile(requestPartName, "", contentType,
value.getBytes(Charset.forName("UTF-8")));
}

for recent versions of jupyter/ipython: use jupyter kernelspec
Full doc: https://ipython.readthedocs.io/en/latest/install/kernel_install.html
$ jupyter kernelspec list
Available kernels:
python2 .../Jupyter/kernels/python2
python3 .../Jupyter/kernels/python3
In my case, the python3 kernel setup was broken because the py3.5 linked was no longer there, replaced by a py3.6
Remove:
$ jupyter kernelspec uninstall python3
Add a new one: Using the Python you wish to add and pointing to the python which runs your jupiter:
$ /path/to/kernel/env/bin/python -m ipykernel install --prefix=/path/to/jupyter/env --name 'python-my-env'
See more examples in https://ipython.readthedocs.io/en/6.5.0/install/kernel_install.html#kernels-for-different-environments
List again:
$ jupyter kernelspec list
Available kernels:
python3 /usr/local/lib/python3.6/site-packages/ipykernel/resources
python2 /Users/stefano/Library/Jupyter/kernels/python2
Doc: https://jupyter-client.readthedocs.io/en/latest/kernels.html#kernelspecs
Kernels available are listed under the kernels
folder in Jupyter DATA DIRECTORY (see http://jupyter.readthedocs.io/en/latest/projects/jupyter-directories.html for details).
For instance on macosx that would be /Users/YOURUSERNAME/Library/Jupyter/kernels/
the kernel is simply described by a kernel.json
file, eg. for /Users/me/Library/Jupyter/kernels/python3/kernel.json
{
"argv": [
"/usr/local/opt/python3/bin/python3.5",
"-m",
"ipykernel",
"-f",
"{connection_file}"
],
"language": "python",
"display_name": "Python 3"
}
Rather then manipulating that by hand, you can use the kernelspec
command (as above). It was previously available through ipython now through jupyter (http://ipython.readthedocs.io/en/stable/install/kernel_install.html#kernels-for-different-environments - https://jupyter-client.readthedocs.io/en/latest/kernels.html#kernelspecs).
$ jupyter kernelspec help
Manage Jupyter kernel specifications.
Subcommands
-----------
Subcommands are launched as `jupyter kernelspec cmd [args]`. For information on
using subcommand 'cmd', do: `jupyter kernelspec cmd -h`.
list

By the way, not strictly related to this question but there's a lot of other kernels available... https://github.com/jupyter/jupyter/wiki/Jupyter-kernels
If I understand your problem well you want the following things:
Unfortunately there is no ultimate solution for what you want, but there are some things by which you can make your life easier.
First you should decide one important thing: do you want to store for every version in your project repository a reference to the version of the media files? So for example if you have a project called example.com, do you need know which style.css it used 2 weeks ago, or the latest is always (or mostly) the best?
If you don't need to know that, the solution is easy:
In most of the cases, however, you want to know this versioning information. In this case you have two choices:
Store every project in one big repository. The advantage of this solution is that you will have only 1 copy of the media repository. The big disadvantage is that it is much harder to switch between project versions (if you checkout to a different version you will always modify ALL projects)
Use submodules (as explained in answer 1). This way you will store the media files in one repository, and the projects will contain only a reference to a specific media repo version. But this way you will normally have many local copies of the media repository, and you cannot easily modify a media file in all projects.
If I were you I would probably choose the first or third solution (symbolic links or submodules). If you choose to use submodules you can still do a lot of things to make your life easier:
Before committing you can rename the submodule directory and put a symlink to a common media directory. When you're ready to commit, you can remove the symlink and remove the submodule back, and then commit.
You can add one of your copy of the media repository as a remote repository to all of your projects.
You can add local directories as a remote this way:
cd /my/project2/media
git remote add project1 /my/project1/media
If you modify a file in /my/project1/media, you can commit it and pull it from /my/project2/media without pushing it to a remote server:
cd /my/project1/media
git commit -a -m "message"
cd /my/project2/media
git pull project1 master
You are free to remove these commits later (with git reset) because you haven't shared them with other users.
It's possible to compile and use tmux within Cgywin. http://sourceforge.net/mailarchive/message.php?msg_id=30850840
If you are using approach with class-based views and different 'action' attrs i mean
Put different URLs in the action for the two forms. Then you'll have two different view functions to deal with the two different forms.
You can easily handle errors from different forms using overloaded get_context_data
method, e.x:
views.py:
class LoginView(FormView):
form_class = AuthFormEdited
success_url = '/'
template_name = 'main/index.html'
def dispatch(self, request, *args, **kwargs):
return super(LoginView, self).dispatch(request, *args, **kwargs)
....
def get_context_data(self, **kwargs):
context = super(LoginView, self).get_context_data(**kwargs)
context['login_view_in_action'] = True
return context
class SignInView(FormView):
form_class = SignInForm
success_url = '/'
template_name = 'main/index.html'
def dispatch(self, request, *args, **kwargs):
return super(SignInView, self).dispatch(request, *args, **kwargs)
.....
def get_context_data(self, **kwargs):
context = super(SignInView, self).get_context_data(**kwargs)
context['login_view_in_action'] = False
return context
template:
<div class="login-form">
<form action="/login/" method="post" role="form">
{% csrf_token %}
{% if login_view_in_action %}
{% for e in form.non_field_errors %}
<div class="alert alert-danger alert-dismissable">
{{ e }}
<a class="panel-close close" data-dismiss="alert">×</a>
</div>
{% endfor %}
{% endif %}
.....
</form>
</div>
<div class="signin-form">
<form action="/registration/" method="post" role="form">
{% csrf_token %}
{% if not login_view_in_action %}
{% for e in form.non_field_errors %}
<div class="alert alert-danger alert-dismissable">
{{ e }}
<a class="panel-close close" data-dismiss="alert">×</a>
</div>
{% endfor %}
{% endif %}
....
</form>
</div>
XML-RPC is part of the Python standard library:
It surprises me that no one mentioned the key difference between these two is that the temp table supports parallel insert while the table variable doesn't. You should be able to see the difference from the execution plan. And here is the video from SQL Workshops on Channel 9.
This also explains why you should use a table variable for smaller tables, otherwise use a temp table, as SQLMenace answered before.
You can use FLOOR
:
select x, ABS(x) - FLOOR(ABS(x))
from (
select 2.938 as x
) a
Output:
x
-------- ----------
2.938 0.938
Or you can use SUBSTRING
:
select x, SUBSTRING(cast(x as varchar(max)), charindex(cast(x as varchar(max)), '.') + 3, len(cast(x as varchar(max))))
from (
select 2.938 as x
) a
You can have it this way:
It is important to mind the commas after each struct item or set of items.
earnings := []LineItemsType{
LineItemsType{
TypeName: "Earnings",
Totals: 0.0,
HasTotal: true,
items: []LineItems{
LineItems{
name: "Basic Pay",
amount: 100.0,
},
LineItems{
name: "Commuter Allowance",
amount: 100.0,
},
},
},
LineItemsType{
TypeName: "Earnings",
Totals: 0.0,
HasTotal: true,
items: []LineItems{
LineItems{
name: "Basic Pay",
amount: 100.0,
},
LineItems{
name: "Commuter Allowance",
amount: 100.0,
},
},
},

I found an easier way by looking at the R script generated by Rattle. It looks like below:
correlations <- cor(mydata[,c(1,3,5:87,89:90,94:98)], use="pairwise", method="spearman")
This works for me. Since it "extends" datepicker we can still use dateFormat:'dd/mm/yy'.
$(function() {
$('.jqueryui-marker-datepicker').datetimepicker({
showSecond: true,
dateFormat: 'dd/mm/yy',
timeFormat: 'hh:mm:ss',
stepHour: 2,
stepMinute: 10,
stepSecond: 10
});
});
Log.v("blah", "blah blah");
You need to add the android Log view in eclipse to see them. There are also other methods depending on the severity of the message (error, verbose, warning, etc..).
You mentioned that you want the regex to match each of those strings, yet you previously mention that the is 1-2 digits before the decimal?
This will match 1-2 digits followed by a possible decimal, followed by another 1-2 digits but FAIL on your example of .33
\d{1,2}\.?\d{1,2}
This will match 0-2 digits followed by a possible deciaml, followed by another 1-2 digits and match on your example of .33
\d{0,2}\.?\d{1,2}
Not sure exactly which one you're looking for.
Yes there is a way to do it.
First declare a class.
//anyfile.ts
export class Custom
{
name: string,
empoloyeeID: number
}
Then in your component import the class
import {Custom} from '../path/to/anyfile.ts'
.....
export class FormComponent implements OnInit {
name: string;
empoloyeeID : number;
empList: Array<Custom> = [];
constructor() {
}
ngOnInit() {
}
onEmpCreate(){
//console.log(this.name,this.empoloyeeID);
let customObj = new Custom();
customObj.name = "something";
customObj.employeeId = 12;
this.empList.push(customObj);
this.name ="";
this.empoloyeeID = 0;
}
}
Another way would be to interfaces read the documentation once - https://www.typescriptlang.org/docs/handbook/interfaces.html
Also checkout this question, it is very interesting - When to use Interface and Model in TypeScript / Angular2
Which version VirtualBox do you use? I found the same problem and when use update latest version on my X64 win7 machine VirtualBox-4.3.4-91027-Win But I uninstall it and back to VirtualBox-4.2.18-88781-Win
It works well, try it until Oracle fix it.
That part is written to stderr, use 2>
to redirect it. For example:
foo > stdout.txt 2> stderr.txt
or if you want in same file:
foo > allout.txt 2>&1
Note: this works in (ba)sh, check your shell for proper syntax
After many attempts I was finally able to get this working. Essentially what I did was download and use the vmware converter to merge the two disks into one. After that I was able to attach the newly created disk to VitrualBox.
The steps involved are very simple:
BEFORE YOU DO ANYTHING!
1) MAKE A BACKUP!!! Even if you follow these instruction, you could screw things up, so make a backup. Just shutdown the VM and then make a copy of the directory where VM resides.
2) Uninstall VMware Tools from the VM that you are going to convert. If for some reason you forget this step, you can still uninstall it after getting everything running under VirtualBox by following these steps. Do yourself the favor and just do it now.
NOW THE FUN PART!!!
1) Download and install the VMware Converter. I used 5.0.1 build-875114, just use the latest.
2) Download and install VirtualBox
3) Fire up VMWare convertor:
4) Click on Convert machine
6) Browse to the .vmx
for your VM and click Next
.
7) Give the new VM a name and select the location where you want to put it. Click Next
8) Click Next
on the Options
screen. You shouldn't have to change anything here.
9) Click Finish
on the Summary
screen to begin the conversion.
10) The conversion should start. This will take a LOOONG time so be patient.
11) Hopefully all went well, if it did, you should see that the conversion is completed:
12) Now open up VirtualBox and click New
.
13) Give your VM a name and select what Type
and Version
it is. Click Next
.
14) Select the size of the memory you want to give it. Click Next
.
15) For the Hard Drive
, click Use and existing hard drive file
and select the newly converted .vmdk
file.
16) Now Click Settings
and select the Storage
menu. The issue is that by default VirtualBox will add the drive as an IDE. This won't work and we need as we need to put it on a SCSI controller.
17) Select the IDE controller and the Remove Controller
button.
18) Now click the Add Controller
button and select Add SCSI Controller
19) Click the Add Hard Disk
button.
20) Click Choose existing disk
21) Select your .vmdk
file. Click OK
22) Select the System
menu.
23) Click Enable IO APIC
. Then click OK
24) Congrats!!! Your VM is now confgiured! Click Start
to startup the VM!

According to MDN, the
split()
method divides a String into an ordered set of substrings, puts these substrings into an array, and returns the array.
var str = 'Hello my friend'
var split1 = str.split(' ') // ["Hello", "my", "friend"]
var split2 = str.split('') // ["H", "e", "l", "l", "o", " ", "m", "y", " ", "f", "r", "i", "e", "n", "d"]
var str = 'something -- something_else'
var splitArr = str.split(' -- ') // ["something", "something_else"]
console.log(splitArr[0]) // something
console.log(splitArr[1]) // something_else
Just copy the remote from the original git clone
command (or from git remote -v
). You will get something like this:
Bitbucket: git+ssh://[email protected]:your_account/my_pro.git
GitHub: git+ssh://[email protected]:your_account/my_pro.git
Next, you need to replace :
with /
next to the domain name.
So install using:
pip install git+ssh://[email protected]/your_account/my_pro.git
Is this what you are looking for ?
Sub getRowCol()
Range("A1").Select ' example
Dim col, row
col = Split(Selection.Address, "$")(1)
row = Split(Selection.Address, "$")(2)
MsgBox "Column is : " & col
MsgBox "Row is : " & row
End Sub
right-click the view in the object-explorer, select "script view as...", then "create to" and then "new query editor window"
This clearly is a bad case of controller logic in a view. It would be better to do this in a controller and return the desired view.
[ChildActionOnly]
public ActionResult Results()
{
EnumerableRowCollection<DataRow> custs = ViewBag.Customers;
bool anyRows = custs.Any();
if(anyRows == false)
{
return View("NoResults");
}
else
{
return View("OtherView");
}
}
Modify NoResults.cshtml to a Partial.
And call this as a Partial view in the parent view
@Html.Partial("Results")
You might have to pass the Customer collection as a model to the Result action or in a ViewDataDictionary due to reasons explained here: Can't access ViewBag in a partial view in ASP.NET MVC3
The ChildActionOnly
attribute will make sure you cannot go to this page by navigating and that this view must be rendered as a partial, thus by a parent view. cfr: Using ChildActionOnly in MVC
Some timing tests for cpython 3 shows that a simple for loop is the fastest way, and it's quite readable. Adding in a function doesn't cause much overhead either:
timeit results (10k iterations):
all(x.pop(v) for v in r) # 0.85
all(map(x.pop, r)) # 0.60
list(map(x.pop, r)) # 0.70
all(map(x.__delitem__, r)) # 0.44
del_all(x, r) # 0.40
<inline for loop>(x, r) # 0.35
def del_all(mapping, to_remove):
"""Remove list of elements from mapping."""
for key in to_remove:
del mapping[key]
For small iterations, doing that 'inline' was a bit faster, because of the overhead of the function call. But del_all
is lint-safe, reusable, and faster than all the python comprehension and mapping constructs.
You could also try putting your code in the Activated event of the form, if you want it to occur, just when the form is activated. You would need to put in a boolean "has executed" check though if it is only supposed to run on the first activation.
angular.module('app').directive('conversation', function() {
return {
restrict: 'E',
link: function ($scope, $elm, $attr) {
$scope.$watch("some_prop", function (newValue, oldValue) {
var typeId = $attr.type-id;
// Your logic.
});
}
};
}
Just want to follow up on the great answer from Paolo Moretti and Browserify. If you are using a transpiler (e.g., babel, typescript) and you have separate folders for source and transpiled code like src/
and dist/
, you could use a variation of the solutions as
With the following directory structure:
app
node_modules
... // normal npm dependencies for app
src
node_modules
app
... // source code
dist
node_modules
app
... // transpiled code
you can then let babel etc to transpile src
directory to dist
directory.
Using symlink we can get rid some levels of nesting:
app
node_modules
... // normal npm dependencies for app
src
node_modules
app // symlinks to '..'
... // source code
dist
node_modules
app // symlinks to '..'
... // transpiled code
A caveat with babel --copy-files The --copy-files
flag of babel
does not deal with symlinks well. It may keep navigating into the ..
symlink and recusively seeing endless files. A workaround is to use the following directory structure:
app
node_modules
app // symlink to '../src'
... // normal npm dependencies for app
src
... // source code
dist
node_modules
app // symlinks to '..'
... // transpiled code
In this way, code under src
will still have app
resolved to src
, whereas babel would not see symlinks anymore.
We can use replace
to change the values in 'mpg' to NA
that corresponds to cyl==4
.
mtcars %>%
mutate(mpg=replace(mpg, cyl==4, NA)) %>%
as.data.frame()
I got this error because the instruction on the Web was
git checkout https://github.com/veripool/verilog-mode
which I did in a directory where (on my own initiative) i had run git init
.
The correct Web instruction (for newbies like me) should have been
git clone https://github.com/veripool/verilog-mode
Think about it this way. If you have a rectangle where one axis is radius and one is angle, and you take the points inside this rectangle that are near radius 0. These will all fall very close to the origin (that is close together on the circle.) However, the points near radius R, these will all fall near the edge of the circle (that is, far apart from each other.)
This might give you some idea of why you are getting this behavior.
The factor that's derived on that link tells you how much corresponding area in the rectangle needs to be adjusted to not depend on the radius once it's mapped to the circle.
Edit: So what he writes in the link you share is, "That’s easy enough to do by calculating the inverse of the cumulative distribution, and we get for r:".
The basic premise is here that you can create a variable with a desired distribution from a uniform by mapping the uniform by the inverse function of the cumulative distribution function of the desired probability density function. Why? Just take it for granted for now, but this is a fact.
Here's my somehwat intuitive explanation of the math. The density function f(r) with respect to r has to be proportional to r itself. Understanding this fact is part of any basic calculus books. See sections on polar area elements. Some other posters have mentioned this.
So we'll call it f(r) = C*r;
This turns out to be most of the work. Now, since f(r) should be a probability density, you can easily see that by integrating f(r) over the interval (0,R) you get that C = 2/R^2 (this is an exercise for the reader.)
Thus, f(r) = 2*r/R^2
OK, so that's how you get the formula in the link.
Then, the final part is going from the uniform random variable u in (0,1) you must map by the inverse function of the cumulative distribution function from this desired density f(r). To understand why this is the case you need to find an advanced probability text like Papoulis probably (or derive it yourself.)
Integrating f(r) you get F(r) = r^2/R^2
To find the inverse function of this you set u = r^2/R^2 and then solve for r, which gives you r = R * sqrt(u)
This totally makes sense intuitively too, u = 0 should map to r = 0. Also, u = 1 shoudl map to r = R. Also, it goes by the square root function, which makes sense and matches the link.
As Scobal's post implies, the datepicker is looking for a Date object - not just a string! So, to modify your example code to do what you want:
var queryDate = new Date('2009/11/01'); // Dashes won't work
$('#datePicker').datepicker('setDate', queryDate);
Then add code for the old location path and new destination as follows:
<configuration>
<location path="services.htm">
<system.webServer>
<httpRedirect enabled="true" destination="http://domain.com/services" httpResponseStatus="Permanent" />
</system.webServer>
</location>
<location path="products.htm">
<system.webServer>
<httpRedirect enabled="true" destination="http://domain.com/products" httpResponseStatus="Permanent" />
</system.webServer>
</location>
</configuration>
You may add as many location paths as necessary.
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File (sdCard.getAbsolutePath() + "/dir1/dir2");
dir.mkdirs();
File file = new File(dir, "filename");
FileOutputStream f = new FileOutputStream(file);

Every process running under the Linux kernel receives its own, unique environment that it inherits from its parent. In this case, the parent will be either a shell itself (spawning a sub shell), or the 'login' program (on a typical system).
As each process' environment is protected, there is no way to 'inject' an environmental variable to every running process, so even if you modify the default shell .rc / profile, it won't go into effect until each process exits and reloads its start up settings.
Look in /etc/ to modify the default start up variables for any particular shell. Just realize that users can (and often do) change them in their individual settings.
Unix is designed to obey the user, within limits.
NB: Bash is not the only shell on your system. Pay careful attention to what the /bin/sh symbolic link actually points to. On many systems, this could actually be dash which is (by default, with no special invocation) POSIXLY correct. Therefore, you should take care to modify both defaults, or scripts that start with /bin/sh will not inherit your global defaults. Similarly, take care to avoid syntax that only bash understands when editing both, aka avoiding bashisms
.
This problem was caused for me by this error which appeared just prior in the application error log.
"A read operation on a large object failed while sending data to the client. A common cause for this is if the application is running in READ UNCOMMITTED isolation level. This connection will be terminated."
I was storing PDFs in a SQL table and when attempting to SELECT from that table it spit out that error, which resulted in the error mentioned in your question.
The solution was to delete the columns that had large amounts of text, in my case Base64 encoded files.
If you want to stop tracking file without deleting the file from your local system, which I prefer for ignoring config/database.yml
file. Simply try:
git rm --cached config/database.yml
# this will delete your file from git history but not from your local system.
now, add this file to .gitignore
file and commit the changes. And from now on, any changes made to config/database.yml will not get tracked by git.
$ echo config/database.yml >> .gitignore
Thanks
I ran into the same problem every time it finds a special character marks it as ??. to solve this, I tried using the encoding: ISO-8859-1
BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("txtPath"),"ISO-8859-1"));
while ((line = br.readLine()) != null) {
}
I hope this can help anyone who sees this post.
Using Retrofit 2.0 you may use this:
@Multipart
@POST("uploadImage")
Call<ResponseBody> uploadImage(@Part("file\"; fileName=\"myFile.png\" ")RequestBody requestBodyFile, @Part("image") RequestBody requestBodyJson);
Make a request:
File imgFile = new File("YOUR IMAGE FILE PATH");
RequestBody requestBodyFile = RequestBody.create(MediaType.parse("image/*"), imgFile);
RequestBody requestBodyJson = RequestBody.create(MediaType.parse("text/plain"),
retrofitClient.getJsonObject(uploadRequest));
//make sync call
Call<ResponseBody> uploadBundle = uploadImpl.uploadImage(requestBodyFile, requestBodyJson);
Response<BaseResponse> response = uploadBundle.execute();
please refer https://square.github.io/retrofit/
The same situation occurred when I was using VSCode with eslint. If you use VSCode,
1 - Click area that name can be both LF or CRLF where at the bottom right of the VScode.
2 - Select LF from the drop-down menu.
That's worked for me.
string.IsNullOrEmpty(Request.QueryString["aspxerrorpath"]) //true -> there is no value
Will return if there is a value
<EditText
android:id="@+id/comments_textbox"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="comments"
android:inputType="textMultiLine"
android:longClickable="false" />
use it to create multi line text box like textArea in Html
This worked for me... just clear the textbox completely as non-numeric keys are pressed.
Private Sub TextBox2_TextChanged(sender As Object, e As EventArgs) Handles TextBox2.TextChanged
If IsNumeric(TextBox2.Text) Then
'nada
Else
TextBox2.Clear()
End If
End Sub
As @Hutch pointed out, one of the major limitations of sp_who2
is that it does not take any parameters so you cannot sort or filter it by default. You can save the results into a temp table, but then the you have to declare all the types ahead of time (and remember to DROP TABLE
).
Instead, you can just go directly to the source on master.dbo.sysprocesses
I've constructed this to output almost exactly the same thing that sp_who2
generates, except that you can easily add ORDER BY
and WHERE
clauses to get meaningful output.
SELECT spid,
sp.[status],
loginame [Login],
hostname,
blocked BlkBy,
sd.name DBName,
cmd Command,
cpu CPUTime,
physical_io DiskIO,
last_batch LastBatch,
[program_name] ProgramName
FROM master.dbo.sysprocesses sp
JOIN master.dbo.sysdatabases sd ON sp.dbid = sd.dbid
ORDER BY spid
You generally want to ignore the SIGPIPE
and handle the error directly in your code. This is because signal handlers in C have many restrictions on what they can do.
The most portable way to do this is to set the SIGPIPE
handler to SIG_IGN
. This will prevent any socket or pipe write from causing a SIGPIPE
signal.
To ignore the SIGPIPE
signal, use the following code:
signal(SIGPIPE, SIG_IGN);
If you're using the send()
call, another option is to use the MSG_NOSIGNAL
option, which will turn the SIGPIPE
behavior off on a per call basis. Note that not all operating systems support the MSG_NOSIGNAL
flag.
Lastly, you may also want to consider the SO_SIGNOPIPE
socket flag that can be set with setsockopt()
on some operating systems. This will prevent SIGPIPE
from being caused by writes just to the sockets it is set on.
It can also be done the following way.
At first rename local branch, then remote branch.
Renaming the local branch:
If logged in another branch,
git branch -m old_branch new_branch
If logged in the same branch,
git branch -m new_branch
Renaming remote branch:
git push origin :old_branch // Delete the remote branch
git push --set-upstream origin new_branch // Create a new remote branch
Other examples:
Python Foreach Loop:
array = ['a', 'b']
for value in array:
print(value)
# a
# b
Python For Loop:
array = ['a', 'b']
for index in range(len(array)):
print("index: %s | value: %s" % (index, array[index]))
# index: 0 | value: a
# index: 1 | value: b
If you want to find the size of all MySQL databases, us this command, it will show their respective sizes in megabytes;
SELECT table_schema "database", sum(data_length + index_length)/1024/1024 "size in MB" FROM information_schema.TABLES GROUP BY table_schema;
If you have large databases, you can use the following command to show the result in gigabytes;
SELECT table_schema "database", sum(data_length + index_length)/1024/1024/1024 "size in GB" FROM information_schema.TABLES GROUP BY table_schema;
If you want to show the size of only a specific database, for example YOUR_DATABASE_NAME
, you could use the following query;
SELECT table_schema "database", sum(data_length + index_length)/1024/1024/1024 "size in GB" FROM information_schema.TABLES WHERE table_schema='YOUR_DATABASE_NAME' GROUP BY table_schema;
Additionally, return values are compatible with asynchronous design paradigms.
You cannot designate a function "async" if it uses ref or out parameters.
In summary, Return Values allow method chaining, cleaner syntax (by eliminating the necessity for the caller to declare additional variables), and allow for asynchronous designs without the need for substantial modification in the future.
