I got the resources on C# (Desktop WPF W/ .NET Framework 4.8) using the code below
{DefaultNamespace}.Properties.Resources.{ResourceName}
As one person may have already suggested,
I passed the ISO 8601 date string directly to moment like so...
`moment.utc('2019-11-03T05:00:00.000Z').format('MM/DD/YYYY')`
or
`moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')`
either of these solutions will give you the same result.
`console.log(moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')) // 11/3/2019`
if ([self.locationManager respondsToSelector:@selector(setAllowsBackgroundLocationUpdates:)]) {
[self.locationManager setAllowsBackgroundLocationUpdates:YES];
}
This is needed for background location tracking since iOS 9.
As of R 3.3.0, one may use startsWith()
as a faster alternative to grepl()
:
which(startsWith(mydata_2$height_seca1, 1578))
When I need to get the directory, not only for the plugins (plugin_dir_path), but a more generic one, you can use __DIR__
, it will give you the path of the directory of the file where is called. Now you can used from functions.php or another file!
Description:
The directory of the file. If used inside an include, the directory of the included file is returned. This is equivalent to dirname(
__FILE__
). This directory name does not have a trailing slash unless it is the root directory. 1
find . -type f | xargs file | grep "ASCII text" | awk -F: '{print $1}'
Use find command to list all files, use file command to verify they are text (not tar,key), finally use awk command to filter and print the result.
Works for me
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$("#btn").click(function() {
alert("email")
});
</script>
savefig
has its own parameter for facecolor
.
I think an even easier way than the accepted answer is to set them globally just once, instead of putting facecolor=fig.get_facecolor()
every time:
plt.rcParams['axes.facecolor']='red'
plt.rcParams['savefig.facecolor']='red'
@Mock
annotation mocks the concerned object.
@InjectMocks
annotation allows to inject into the underlying object the different (and relevant) mocks created by @Mock
.
Both are complementary.
As an alternative to curl
, you can use HTTPie, it'a CLI, cURL-like tool for humans.

See it work:
They mean different things.
If you use var
the variable is declared within the scope you are in (e.g. of the function). If you don't use var
, the variable bubbles up through the layers of scope until it encounters a variable by the given name or the global object (window, if you are doing it in the browser), where it then attaches. It is then very similar to a global variable. However, it can still be deleted with delete
(most likely by someone else's code who also failed to use var
). If you use var
in the global scope, the variable is truly global and cannot be deleted.
This is, in my opinion, one of the most dangerous issues with javascript, and should be deprecated, or at least raise warnings over warnings. The reason is, it's easy to forget var
and have by accident a common variable name bound to the global object. This produces weird and difficult to debug behavior.
This may help a small percentage of people still scratching their heads. Text copied from clipboard into VSCode may have an invisible hard space character preventing wrapping. Check it with HTML inspector
By default .
(any character) does not match newline characters.
This means you can simply match zero or more of any character then append the end tag.
Find: <li><a href="#">.*
Replace: $0</a>
To Send bold,italic,fixed width code you can use this :
# Sending a HTML formatted message
bot.send_message(chat_id=@yourchannelname,
text="*boldtext* _italictext_ `fixed width font` [link] (http://google.com).",
parse_mode=telegram.ParseMode.MARKDOWN)
make sure you have enabled the bot as your admin .Then only it can send message
if [[ $STR == *pattern* ]]
then
echo "It is the string!"
else
echo "It's not him!"
fi
Works for me! GNU bash, version 4.3.11(1)-release (x86_64-pc-linux-gnu)
If your Service is started by your app then actually your service is running on main process. so when app is killed service will also be stopped. So what you can do is, send broadcast from onTaskRemoved
method of your service as follows:
Intent intent = new Intent("com.android.ServiceStopped");
sendBroadcast(intent);
and have an broadcast receiver which will again start a service. I have tried it. service restarts from all type of kills.
Use @ViewChildren
from @angular/core
to get a reference to the components
template
<div *ngFor="let v of views">
<customcomponent #cmp></customcomponent>
</div>
component
import { ViewChildren, QueryList } from '@angular/core';
/** Get handle on cmp tags in the template */
@ViewChildren('cmp') components:QueryList<CustomComponent>;
ngAfterViewInit(){
// print array of CustomComponent objects
console.log(this.components.toArray());
}
The issue is not with the version of node. Instead, it is the way NodeJS is installed by default in Ubuntu. When running a Node application in Ubuntu you have to run nodejs somethign.js
instead of node something.js
So the application name called in the terminal is nodejs
and not node
. This is why there is a need for a symlink to simply forward all the commands received as node
to nodejs
.
sudo ln -s /usr/bin/nodejs /usr/bin/node
I think you might be able to use the ExpandProperty
parameter of Select-Object
.
For example, to get the list of the current directory and just have the Name property displayed, one would do the following:
ls | select -Property Name
This is still returning DirectoryInfo or FileInfo objects. You can always inspect the type coming through the pipeline by piping to Get-Member (alias gm
).
ls | select -Property Name | gm
So, to expand the object to be that of the type of property you're looking at, you can do the following:
ls | select -ExpandProperty Name
In your case, you can just do the following to have a variable be an array of strings, where the strings are the Name property:
$objects = ls | select -ExpandProperty Name
Redirecting stderr
to stdout
seems to also do the trick without any other commands/scriptblock wrappers although I can't find an explanation why it works that way..
# test.ps1
$ErrorActionPreference = "Stop"
aws s3 ls s3://xxx
echo "==> pass"
aws s3 ls s3://xxx 2>&1
echo "shouldn't be here"
This will output the following as expected (the command aws s3 ...
returns $LASTEXITCODE = 255
)
PS> .\test.ps1
An error occurred (AccessDenied) when calling the ListObjectsV2 operation: Access Denied
==> pass
you can do it like this for multiple order by
IOrderedEnumerable<JToken> sort;
if (query.OrderBys[0].IsDESC)
{
sort = jarry.OrderByDescending(r => (string)r[query.OrderBys[0].Key]);
}
else
{
sort = jarry.OrderBy(r =>
(string) r[query.OrderBys[0].Key]);
}
foreach (var item in query.OrderBys.Skip(1))
{
if (item.IsDESC)
{
sort = sort.ThenByDescending(r => (string)r[item.Key]);
}
else
{
sort = sort.ThenBy(r => (string)r[item.Key]);
}
}
Add a column to your existing data to get rid of the hour:minute:second time stamp on each row:
=DATE(YEAR(A1), MONTH(A1), DAY(A1))
Extend this down the length of your data. Even easier: quit collecting the hh:mm:ss data if you don't need it. Assuming your date/time was in column A, and your value was in column B, you'd put the above formula in column C, and auto-extend it for all your data.
Now, in another column (let's say E), create a series of dates corresponding to each day of the specific month you're interested in. Just type the first date, (for example, 10/7/2016 in E1), and auto-extend. Then, in the cell next to the first date, F1, enter:
=SUMIF(C:C, E1, B:B )
autoextend the formula to cover every date in the month, and you're done. Begin at 1/1/2016, and auto-extend for the whole year if you like.
The default values for minOccurs
and maxOccurs
are 1. Thus:
<xsd:element minOccurs="1" name="asdf"/>
cardinality is [1-1] Note: if you specify only minOccurs attribute, it can't be greater than 1, because the default value for maxOccurs is 1.
<xsd:element minOccurs="5" maxOccurs="2" name="asdf"/>
invalid
<xsd:element maxOccurs="2" name="asdf"/>
cardinality is [1-2] Note: if you specify only maxOccurs attribute, it can't be smaller than 1, because the default value for minOccurs is 1.
<xsd:element minOccurs="0" maxOccurs="0"/>
is a valid combination which makes the element prohibited.

None of these answers really work. As others noted the Cors package will only use the Access-Control-Allow-Origin header if the request had an Origin header. But you can't generally just add an Origin header to the request because browsers may try to regulate that too.
If you want a quick and dirty way to allow cross site requests to a web api, it's really a lot easier to just write a custom filter attribute:
public class AllowCors : ActionFilterAttribute
{
public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
{
if (actionExecutedContext == null)
{
throw new ArgumentNullException("actionExecutedContext");
}
else
{
actionExecutedContext.Response.Headers.Remove("Access-Control-Allow-Origin");
actionExecutedContext.Response.Headers.Add("Access-Control-Allow-Origin", "*");
}
base.OnActionExecuted(actionExecutedContext);
}
}
Then just use it on your Controller action:
[AllowCors]
public IHttpActionResult Get()
{
return Ok("value");
}
I won't vouch for the security of this in general, but it's probably a lot safer than setting the headers in the web.config since this way you can apply them only as specifically as you need them.
And of course it is simple to modify the above to allow only certain origins, methods etc.
For anyone looking for a Xamarin implementation (since events are done differently in C#), I simply created this NavClickHandler
class as follows:
public class NavClickHandler : Java.Lang.Object, View.IOnClickListener
{
private Activity mActivity;
public NavClickHandler(Activity activity)
{
this.mActivity = activity;
}
public void OnClick(View v)
{
DrawerLayout drawer = (DrawerLayout)mActivity.FindViewById(Resource.Id.drawer_layout);
if (drawer.IsDrawerOpen(GravityCompat.Start))
{
drawer.CloseDrawer(GravityCompat.Start);
}
else
{
drawer.OpenDrawer(GravityCompat.Start);
}
}
}
Then, assigned a custom hamburger menu button like this:
SupportActionBar.SetDisplayHomeAsUpEnabled(true);
SupportActionBar.SetDefaultDisplayHomeAsUpEnabled(false);
this.drawerToggle.DrawerIndicatorEnabled = false;
this.drawerToggle.SetHomeAsUpIndicator(Resource.Drawable.MenuButton);
And finally, assigned the drawer menu toggler a ToolbarNavigationClickListener of the class type I created earlier:
this.drawerToggle.ToolbarNavigationClickListener = new NavClickHandler(this);
And then you've got a custom menu button, with click events handled.
You can read the manpage for proc for more detail, but in summary you can read /proc/[number]/stat to get the information about a process. This is also used by the 'ps' command.
All the fields and their scanf format specifiers are documented in the proc manpage.
Here are some of the information from the manpage copied (it is quite long):
pid %d The process ID.
comm %s
The filename of the executable, in parentheses. This is
visible whether or not the executable is swapped out.
state %c
One character from the string "RSDZTW" where R is runâ
ning, S is sleeping in an interruptible wait, D is waitâ
ing in uninterruptible disk sleep, Z is zombie, T is
traced or stopped (on a signal), and W is paging.
ppid %d
The PID of the parent.
pgrp %d
The process group ID of the process.
session %d
The session ID of the process.
tty_nr %d
The tty the process uses.
tpgid %d
The process group ID of the process which currently owns
the tty that the process is connected to.
Another useful option in IDEA to switch off or keep checked if you really need that:
Preferences -> Code Style -> Detect and use existing file indents for editing
if your team is going to switch to tab formatting with existing code written with spaces, uncheck that
In Laravel 5.x there is no paths.php
so you should edit public/index.php
and change this lines in order to to pint to your bootstrap
directory:
require __DIR__.’/../bootstrap/autoload.php’;
$app = require_once __DIR__.’/../bootstrap/app.php’;
for more information you can read this article.
As everyone said, references can't be null. That is because, a reference refers to an object. In your code:
// this compiles, but doesn't work, and does this even mean anything?
if (&str == NULL)
you are taking the address of the object str
. By definition, str
exists, so it has an address. So, it cannot be NULL
. So, syntactically, the above is correct, but logically, the if
condition is always going to be false.
About your questions: it depends upon what you want to do. Do you want the function to be able to modify the argument? If yes, pass a reference. If not, don't (or pass reference to const
). See this C++ FAQ for some good details.
In general, in C++, passing by reference is preferred by most people over passing a pointer. One of the reasons is exactly what you discovered: a reference can't be NULL
, thus avoiding you the headache of checking for it in the function.
I solved this by getting the Bluetooth name, but not from the BluetoothAdapter
(that needs Bluetooth permission).
Here's the code:
Settings.Secure.getString(getContentResolver(), "bluetooth_name");
No extra permissions needed.
Entity interface
public interface Entity<I> extends Serializable {
/**
* @return entity identity
*/
I getId();
/**
* @return HashCode of entity identity
*/
int identityHashCode();
/**
* @param other
* Other entity
* @return true if identities of entities are equal
*/
boolean identityEquals(Entity<?> other);
}
Basic implementation for all Entities, simplifies Equals/Hashcode implementations:
public abstract class AbstractEntity<I> implements Entity<I> {
@Override
public final boolean identityEquals(Entity<?> other) {
if (getId() == null) {
return false;
}
return getId().equals(other.getId());
}
@Override
public final int identityHashCode() {
return new HashCodeBuilder().append(this.getId()).toHashCode();
}
@Override
public final int hashCode() {
return identityHashCode();
}
@Override
public final boolean equals(final Object o) {
if (this == o) {
return true;
}
if ((o == null) || (getClass() != o.getClass())) {
return false;
}
return identityEquals((Entity<?>) o);
}
@Override
public String toString() {
return getClass().getSimpleName() + ": " + identity();
// OR
// return ReflectionToStringBuilder.reflectionToString(this, ToStringStyle.MULTI_LINE_STYLE);
}
}
Room Entity impl:
@Entity
@Table(name = "ROOM")
public class Room extends AbstractEntity<Integer> {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "room_id")
private Integer id;
@Column(name = "number")
private String number; //immutable
@Column(name = "capacity")
private Integer capacity;
@ManyToOne(fetch = FetchType.LAZY, optional = false)
@JoinColumn(name = "building_id")
private Building building; //immutable
Room() {
// default constructor
}
public Room(Building building, String number) {
// constructor with required field
notNull(building, "Method called with null parameter (application)");
notNull(number, "Method called with null parameter (name)");
this.building = building;
this.number = number;
}
public Integer getId(){
return id;
}
public Building getBuilding() {
return building;
}
public String getNumber() {
return number;
}
public void setCapacity(Integer capacity) {
this.capacity = capacity;
}
//no setters for number, building nor id
}
I don't see a point of comparing equality of entities based on business fields in every case of JPA Entities. That might be more of a case if these JPA entities are thought of as Domain-Driven ValueObjects, instead of Domain-Driven Entities (which these code examples are for).
My best answer for this is to simply use format painter. This might be a bit of a pain, but it works rather well as the problem you are facing is that Gridlines are covered by fill and other effects that are layered on top. Imagine putting a piece of white paper on top of your grid, the grid lines are present underneath, but they just don't show.
So try:
From my experience this is the easiest way to do this quickly. Especially when pasting things in and out of excel.
Again this is not the programmatic way of solving this problem.
Surround that select with parentheses.
SET @v1 := (SELECT COUNT(*) FROM user_rating);
SELECT @v1;
I've used a few CSS hacks and targeted Chrome/Safari/Firefox/IE individually, as each browser renders selects a bit differently. I've tested on all browsers except IE.
For Safari/Chrome, set the height
and line-height
you want for your <select />
.
For Firefox, we're going to kill Firefox's default padding and border, then set our own. Set padding to whatever you like.
For IE 8+, just like Chrome, we've set the height
and line-height
properties. These two media queries
can be combined. But I kept it separate for demo purposes. So you can see what I'm doing.
Please note, for the height/line-height
property to work in Chrome/Safari OSX, you must set the background
to a custom value. I changed the color in my example.
Here's a jsFiddle of the below: http://jsfiddle.net/URgCB/4/
For the non-hack route, why not use a custom select plug-in via jQuery? Check out this: http://codepen.io/wallaceerick/pen/ctsCz
HTML:
<select>
<option>Here's one option</option>
<option>here's another option</option>
</select>
CSS:
@media screen and (-webkit-min-device-pixel-ratio:0) { /*safari and chrome*/
select {
height:30px;
line-height:30px;
background:#f4f4f4;
}
}
select::-moz-focus-inner { /*Remove button padding in FF*/
border: 0;
padding: 0;
}
@-moz-document url-prefix() { /* targets Firefox only */
select {
padding: 15px 0!important;
}
}
@media screen\0 { /* IE Hacks: targets IE 8, 9 and 10 */
select {
height:30px;
line-height:30px;
}
}
Below is code that I currently use to pull data from a MS SQL Server 2008 into VBA. You need to make sure you have the proper ADODB reference [VBA Editor->Tools->References] and make sure you have Microsoft ActiveX Data Objects 2.8 Library checked, which is the second from the bottom row that is checked (I'm using Excel 2010 on Windows 7; you might have a slightly different ActiveX version, but it will still begin with Microsoft ActiveX):
Sub Module for Connecting to MS SQL with Remote Host & Username/Password
Sub Download_Standard_BOM()
'Initializes variables
Dim cnn As New ADODB.Connection
Dim rst As New ADODB.Recordset
Dim ConnectionString As String
Dim StrQuery As String
'Setup the connection string for accessing MS SQL database
'Make sure to change:

There's an Abstract Class Dictionary
http://docs.oracle.com/javase/6/docs/api/java/util/Dictionary.html
However this requires implementation.
Java gives us a nice implementation called a Hashtable
http://docs.oracle.com/javase/6/docs/api/java/util/Hashtable.html
The issue here is that ng-repeat
creates its own scope, so when you do selected=$index
it creates a new a selected
property in that scope rather than altering the existing one. To fix this you have two options:
Change the selected property to a non-primitive (ie object or array, which makes javascript look up the prototype chain) then set a value on that:
$scope.selected = {value: 0};
<a ng-click="selected.value = $index">A{{$index}}</a>
or
Use the $parent
variable to access the correct property. Though less recommended as it increases coupling between scopes
<a ng-click="$parent.selected = $index">A{{$index}}</a>

use sudo with the command:
sudo apt-get remove --purge mongodb
apt-get autoremove --purge mongodb
On Ubuntu:
Wed Jan 27 10:21:32 Error: couldn't connect to server 127.0.0.1 shell/mongo.js:84 exception: connect failed
Solution
look for if mongodb is running by following command:
ps -ef | grep mongo
If mongo is not running you get:
vimal 1806 1698 0 10:11 pts/0 00:00:00 grep --color=auto mongo
You are seeing that the mongo daemon is not there.
Then start it through configuration file(with root priev):
root@vimal:/data# mongod --config /etc/mongodb.conf &
[1] 2131
root@vimal:/data# all output going to: /var/log/mongodb/mongodb.log
you can see the other details:
root@vimal:~# more /etc/mongodb.conf
Open a new terminal to see the result of mongod --config /etc/mongodb.conf & then type mongo. It should be running or grep
root@vimal:/data# ps -ef | grep mongo
root 3153 1 2 11:39 ? 00:00:23 mongod --config /etc/mongodb.conf
root 3772 3489 0 11:55 pts/1 00:00:00 grep --color=auto mongo
NOW
root@vimal:/data# mongo
MongoDB shell version: 2.0.4
connecting to: test
you get the mongoDB shell
This is not the end of story. I will post the repair method so that it starts automatically every time, most development machine shutdowns every day and the VM must have mongo started automatically at next boot.
You can convert it to a timedelta with a day precision. To extract the integer value of days you divide it with a timedelta of one day.
>>> x = np.timedelta64(2069211000000000, 'ns')
>>> days = x.astype('timedelta64[D]')
>>> days / np.timedelta64(1, 'D')

Or, as @PhillipCloud suggested, just days.astype(int)
since the timedelta
is just a 64bit integer that is interpreted in various ways depending on the second parameter you passed in ('D'
, 'ns'
, ...).
You can find more about it here.
I used to solve this issue by deleting the corresponding failed to download artifact directory in my local repo. Next time I run the maven command the artifact download is triggered again. Therefore I'd say it's a client side setting.
Nexus side (server repo side), this issue is solved configuring a scheduled task.
Client side, this is done using -U
, as you already pointed out.
You can write a PL/SQL function to return that cursor (or you could put that function in a package if you have more code related to this):
CREATE OR REPLACE FUNCTION get_allitems
RETURN SYS_REFCURSOR
AS
my_cursor SYS_REFCURSOR;
BEGIN
OPEN my_cursor FOR SELECT * FROM allitems;
RETURN my_cursor;
END get_allitems;
This will return the cursor.
Make sure not to put your SELECT
-String into quotes in PL/SQL when possible. Putting it in strings means that it can not be checked at compile time, and that it has to be parsed whenever you use it.
If you really need to use dynamic SQL you can put your query in single quotes:
OPEN my_cursor FOR 'SELECT * FROM allitems';
This string has to be parsed whenever the function is called, which will usually be slower and hides errors in your query until runtime.
Make sure to use bind-variables where possible to avoid hard parses:
OPEN my_cursor FOR 'SELECT * FROM allitems WHERE id = :id' USING my_id;
By far the easiest way is to log in GitHub account:
yourUsername/yourRepository
for example mbaric/zpropertyz
.gitHubUsername/nameOfTheRepository
and click on the button below which says: I understand the consequences, delete the repositoryThe Hashtable
is a loosely-typed data structure, so you can add keys and values of any type to the Hashtable
. The Dictionary
class is a type-safe Hashtable
implementation, and the keys and values are strongly typed. When creating a Dictionary
instance, you must specify the data types for both the key and value.
Use SQL Server Migration Assistant (SSMA)
In addition to MySQL it supports Oracle, Sybase and MS Access.
It appears to be quite smart and capable of handling even nontrivial transfers. It also got some command line interface (in addition to GUI) so theoretically it can be integrated into some batch load process.
This the current download link for MySQL version https://www.microsoft.com/en-us/download/details.aspx?id=54257
The current (June 2016) stable version 6.0.1 crashes with the current (5.3.6) MySQL ODBC driver while transferring data. Everything 64 bit. The 5.3 version with the 5.1.13 ODBC driver works fine.
My solution was to have a proxy server accept REST, issue the SOAP request, and return result, using PHP.
Time to implement: 15-30 minutes.
Not most elegant, but solid.
dplyr version 0.3 added a new rename()
function that works just like plyr::rename()
.
df <- rename(df, new_name = old_name)
This worked:
$("#theSelectId").prepend("<option value='' selected='selected'></option>");
Firebug Output:
<select id="theSelectId">
<option selected="selected" value=""/>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
You could also use .prependTo
if you wanted to reverse the order:
?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????
Or you can use this javascript
$(function () {
$("#projectKey").change(function () {
alert($('#projectKey option:selected').text());
});
});
Use DATESTR
>> datestr(40189)
ans =
12-Jan-0110
Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM
>> datenum(2010,1,11)
ans =
734149
>> datenum(2010,1,11)-40189
ans =
693960
>> datestr(40189+693960)
ans =
11-Jan-2010
In other words, to convert any serial Excel date, call
datestr(excelSerialDate + 693960)
EDIT
To get the date in mm/dd/yyyy format, call datestr
with the specified format
excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010
Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things
excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010
Here you go this should give you the correct answers every time!

If you are using qmake, the standard Qt build system, just add a line to the .pro
file as documented in the qmake Variable Reference:
INCLUDEPATH += <your path>
If you are using your own build system, you create a project by selecting "Import of Makefile-based project". This will create some files in your project directory including a file named <your project name>.includes
. In that file, simply list the paths you want to include, one per line. Really all this does is tell Qt Creator where to look for files to index for auto completion. Your own build system will have to handle the include paths in its own way.
As explained in the Qt Creator Manual, <your path>
must be an absolute path, but you can avoid OS-, host- or user-specific entries in your .pro
file by using $$PWD
which refers to the folder that contains your .pro
file, e.g.
INCLUDEPATH += $$PWD/code/include
I'm not aware of anything built-in. It's pretty simple to implement:
class assertMethodIsCalled(object):
def __init__(self, obj, method):
self.obj = obj
self.method = method
def called(self, *args, **kwargs):
self.method_called = True
self.orig_method(*args, **kwargs)
def __enter__(self):
self.orig_method = getattr(self.obj, self.method)
setattr(self.obj, self.method, self.called)
self.method_called = False
def __exit__(self, exc_type, exc_value, traceback):
assert getattr(self.obj, self.method) == self.called,
"method %s was modified during assertMethodIsCalled" % self.method
setattr(self.obj, self.method, self.orig_method)
# If an exception was thrown within the block, we've already failed.
if traceback is None:
assert self.method_called,
"method %s of %s was not called" % (self.method, self.obj)
class test(object):
def a(self):
print "test"
def b(self):
self.a()
obj = test()
with assertMethodIsCalled(obj, "a"):
obj.b()
This requires that the object itself won't modify self.b, which is almost always true.
Slightly more compact:
df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df = df.sort_index()
print(df)
Note:
sort
has been deprecated, replaced by sort_index
for this scenarioinplace
as it is usually harder to read and prevents chaining. See explanation in answer here:

I think you should read this to learn a little about submodule. It's well-written, and it doesn't take much time to read it.
If you haven't already committed your changes, just use git checkout
to move to the new branch and then commit them normally - changes to files are not tied to a particular branch until you commit them.
If you have already committed your changes:
git log
and remember the SHA of the commit you want to move.git cherry-pick SHA
substituting the SHA from above.git reset HEAD~1
to reset back before your wrong-branch commit.cherry-pick
takes a given commit and applies it to the currently checked-out head, thus allowing you to copy the commit over to a new branch.
The formula would be (original - discounted)/original
. i.e. (365-165)/365 = 0.5479...
After trying many ways and libraries I decided to create a new font (with Glyphs or this tutorial) and add my SVG files to it, then use "Text" component with my custom font.
Hope this helps anyone that has the same problem with SVG in react-native.

I had existing data in the first column and they were 0's. First I made the first column nullable. Then I set the data for the column to null. Then I set the column as an index. Then I made it a primary key with auto incrementing turned on. This is where I used another persons answer above:
ALTER TABLE `table_name` CHANGE COLUMN `colum_name` `colum_name` INT(11) NOT NULL AUTO_INCREMENT FIRST;
This Added numbers to all the rows of this table starting at one. If I ran the above code first it wasn't working because all the values were 0's. And making it an index was also required before making it auto incrementing. Next I made the column a primary key.

For a similar post a long time ago there seems to be issues with making table visibility hidden.
You have two options, one is to use the display:none
attribute.
Or two wrap the table in a div and make the div hidden.
<div id="wrapper" style="visibility:hidden">
<table>
<tr>
<td>

Taken from the Multimarkdown Users Guide (thanks to @MultiMarkdown on Twitter for pointing it out)
[Some Text][]
will link to a header named “Some Text”
e.g.
### Some Text ###
An optional label of your choosing to help disambiguate cases where multiple headers have the same title:
### Overview [MultiMarkdownOverview] ##
This allows you to use [MultiMarkdownOverview] to refer to this section specifically, and not another section named Overview. This works with atx- or settext-style headers.
If you have already defined an anchor using the same id that is used by a header, then the defined anchor takes precedence.
In addition to headers within the document, you can provide labels for images and tables which can then be used for cross-references as well.
we starting from conversion [ JSONArray -> List < JSONObject > ]
public static List<JSONObject> getJSONObjectListFromJSONArray(JSONArray array)
throws JSONException {
ArrayList<JSONObject> jsonObjects = new ArrayList<>();
for (int i = 0;
i < (array != null ? array.length() : 0);
jsonObjects.add(array.getJSONObject(i++))
);
return jsonObjects;
}
next create generic version replacing array.getJSONObject(i++) with POJO
example :
public <T> static List<T> getJSONObjectListFromJSONArray(Class<T> forClass, JSONArray array)
throws JSONException {
ArrayList<Tt> tObjects = new ArrayList<>();
for (int i = 0;
i < (array != null ? array.length() : 0);
tObjects.add( (T) createT(forClass, array.getJSONObject(i++)))
);
return tObjects;
}
private static T createT(Class<T> forCLass, JSONObject jObject) {
// instantiate via reflection / use constructor or whatsoever
T tObject = forClass.newInstance();
// if not using constuctor args fill up
//
// return new pojo filled object
return tObject;

Android 4.4 (Kit Kat) does have a new sniffing capability for Bluetooth. You should give it a try.
If you don’t own a sniffing device however, you aren’t necessarily out of luck. In many cases we can obtain positive results with a new feature introduced in Android 4.4: the ability to capture all Bluetooth HCI packets and save them to a file.
When the Analyst has finished populating the capture file by running the application being tested, he can pull the file generated by Android into the external storage of the device and analyze it (with Wireshark, for example).
Once this setting is activated, Android will save the packet capture to /sdcard/btsnoop_hci.log to be pulled by the analyst and inspected.
Type the following in case /sdcard/
is not the right path on your particular device:
adb shell echo \$EXTERNAL_STORAGE
We can then open a shell and pull the file: $adb pull /sdcard/btsnoop_hci.log and inspect it with Wireshark, just like a PCAP collected by sniffing WiFi traffic for example, so it is very simple and well supported:
You can enable this by going to Settings->Developer Options, then checking the box next to "Bluetooth HCI Snoop Log."
@tableName
Table variables are alive for duration of the script running only i.e. they are only session level objects.
To test this, open two query editor windows under sql server management studio, and create table variables with same name but different structures. You will get an idea. The @tableName
object is thus temporary and used for our internal processing of data, and it doesn't contribute to the actual database structure.
There is another type of table object which can be created for temporary use. They are #tableName
objects declared like similar create statement for physical tables:
Create table #test (Id int, Name varchar(50))
This table object is created and stored in temp database. Unlike the first one, this object is more useful, can store large data and takes part in transactions etc. These tables are alive till the connection is open. You have to drop the created object by following script before re-creating it.
IF OBJECT_ID('tempdb..#test') IS NOT NULL
DROP TABLE #test
Hope this makes sense !
#the_div input {
margin: 0 auto;
}
I'm not sure if this works in good ol' IE6, so you might have to do this instead.
/* IE 6 (probably) */
#the_div {
text-align: center;
}
You could add a method to String to make it more semantic:
String.metaClass.getNotBlank = { !delegate.allWhitespace }
which let's you do:
groovy:000> foo = ''
===>
groovy:000> foo.notBlank
===> false
groovy:000> foo = 'foo'
===> foo
groovy:000> foo.notBlank
===> true
So the problem as I see it is that you can't get the absolute path to a parent directory in maven.
<rant> I've heard this talked about as an anti-pattern, but for every anti-pattern there is real, legitimate use case for it, and I'm sick of maven telling me I can only follow their patterns.</rant>
So the work around I found was to use antrun. Try this in the child pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<id>getMainBaseDir</id>
<phase>validate</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<exportAntProperties>true</exportAntProperties>
<target>
<!--Adjust the location below to your directory structure -->
<property name="main.basedir" location="./.." />
<echo message="main.basedir=${main.basedir}"/>
</target>
</configuration>
</execution>
</executions>
</plugin>
If you run mvn verify
you should see something like this:
main:
[echo] main.basedir=C:\src\parent.project.dir.name
You can then use ${main.basedir}
in any of the other plugins, etc. Took me a while to figure this out, so hope it helps someone else.
If you are looking for a generic way of doing this via MySQL, you could simply use a SELECT
statement, and add the WHERE
clause to it.
This will grab all fields for all rows, where the date stored in field "date" is before "now".
SELECT * FROM table WHERE UNIX_TIMESTAMP(`date`) < UNIX_TIMESTAMP()
Personally, I found this method to be more gentle on newbies in MySQL, since it uses the standard SELECT statement with WHERE to fetch the results. Obviously, you could grab only the fields relevant if you wanted to, by listing them instead of using a wildcard (*).
For me it was important to delete the "php.executablePath" path from the VS code settings and leave only the path to PHP in the Path variable.
When I had the Path variable together with php.executablePath, an irritating error still occurred (despite the fact that the path to php was correct).
I found that the fast way is by using HashMap .
first put your Object or your list of object in a HashMap , second send it through putExtra method.
//first
HashMap<String,Customer> customerMap=new HashMap<>();
customerMap.put("customer", yourCustomerObjects);
//then you put and send this hashMap object through an intent
Intent i= new Intent(YourCurrentActivity.this,Destination.class);
i.putExtra("customerMap",customerMap);
startActivity(i)
//so then you get this data at the destinations class like this :
HashMap<String,Customer> received=(HashMap<String,Customer>)getIntent().getSerializableExtra("customerMap");
//then you get your object from the HashMap
Customer mCustmer=received.get("customer");
you can use @see
to do that:
sample:
interface View {
/**
* @return true: have read contact and call log permissions, else otherwise
* @see #requestReadContactAndCallLogPermissions()
*/
boolean haveReadContactAndCallLogPermissions();
/**
* if not have permissions, request to user for allow
* @see #haveReadContactAndCallLogPermissions()
*/
void requestReadContactAndCallLogPermissions();
}
import org.apache.commons.io.FileUtils;
List<String> directory = new ArrayList();
directory.add("test-output");
directory.add("Reports/executions");
directory.add("Reports/index.html");
directory.add("Reports/report.properties");
for(int count = 0 ; count < directory.size() ; count ++)
{
String destination = directory.get(count);
deleteDirectory(destination);
}
public void deleteDirectory(String path) {
File file = new File(path);
if(file.isDirectory()){
System.out.println("Deleting Directory :" + path);
try {
FileUtils.deleteDirectory(new File(path)); //deletes the whole folder
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else {
System.out.println("Deleting File :" + path);
//it is a simple file. Proceed for deletion
file.delete();
}
}
Works like a Charm . For both folder and files . Salam :)
For Microsoft Azure, it's slightly different.
Azure has a special CORS setting that needs to be set. It's essentially the same thing behind the scenes, but simply setting the header joshuarh mentions will not work. The Azure documentation for enabling cross domain can be found here:
https://docs.microsoft.com/en-us/azure/app-service-api/app-service-api-cors-consume-javascript
I fiddled around with this for a few hours before realizing my hosting platform had this special setting.
One major disadvantage of SPA - SEO. Only recently Google and Bing started indexing Ajax-based pages by executing JavaScript during crawling, and still in many cases pages are being indexed incorrectly.
While developing SPA, you will be forced to handle SEO issues, probably by post-rendering all your site and creating static html snapshots for crawler's use. This will require a solid investment in a proper infrastructures.
Since writing this answer a while ago, I gain much more experience with Single Page Apps (namely, AngularJS 1.x) - so I have more info to share.
In my opinion, the main disadvantage of SPA applications is SEO, making them limited to kind of "dashboard" apps only. In addition, you are going to have a much harder times with caching, compared to classic solutions. For example, in ASP.NET caching is extreamly easy - just turn on OutputCaching and you are good: the whole HTML page will be cached according to URL (or any other parameters). However, in SPA you will need to handle caching yourself (by using some solutions like second level cache, template caching, etc..).
Now that I've separated the classes to .h and .cpp files do I need to use a makefile or can I still use the "g++ main.cpp" command?
Compiling several files at once is a poor choice if you are going to put that into the Makefile.
Normally in a Makefile (for GNU/Make), it should suffice to write that:
# "all" is the name of the default target, running "make" without params would use it
all: executable1
# for C++, replace CC (c compiler) with CXX (c++ compiler) which is used as default linker
CC=$(CXX)
# tell which files should be used, .cpp -> .o make would do automatically
executable1: file1.o file2.o
That way make
would be properly recompiling only what needs to be recompiled. One can also add few tweaks to generate the header file dependencies - so that make would also properly rebuild what's need to be rebuilt due to the header file changes.
As far as i know %d
means decadic which is number without decimal point. if you want to load double value, use %lf
conversion (long float). for printf your values are wrong for same reason, %d
is used only for integer (and possibly chars if you know what you are doing) numbers.
Example:
double a,b;
printf("--------\n"); //seperate lines
scanf("%lf",&a);
printf("--------\n");
scanf("%lf",&b);
printf("%lf %lf",a,b);
use CURL luke :) seriously, thats one of the best ways to do it AND you get the response.
Personally, I'd return the full, native datetime value and format this in the client code.
That way, you can use the user's locale setting to give the correct meaning to that user.
"11/12" is ambiguous. Is it:

As you can see no version higher than 2.9.0
has been published to the npm repository. Strangely they have versions higher than this on GitHub. I would suggest opening an issue with the maintainers on this.
For now you can manually install the package via the tarball URL of the required release:
npm install https://github.com/ionic-team/ionic-native/tarball/v3.5.0
For my case, the issue was with using Lombok's experimental feature @UtilityClass in my java project in Intellij Idea, to annotate a class methods as "static". When I explicitly made each method of the class as "static" instead of using the annotation, all the compilation issues disappeared.
This works for 4.0.

Take a look at this article on Simple-talk.com by Pop Rivett. It walks you through creating a generic trigger that will log the OLDVALUE and the NEWVALUE for all updated columns. The code is very generic and you can apply it to any table you want to audit, also for any CRUD operation i.e. INSERT, UPDATE and DELETE. The only requirement is that your table to be audited should have a PRIMARY KEY (which most well designed tables should have anyway).
Here's the code relevant for your GUESTS Table.

AND OBJECTPROPERTY(id, N'IsUserTable') = 1)

I had same problem. It was resolved by running same code in Administrator Console.

You want win.Sleep(milliseconds)
, methinks.
Yeah, you definitely don't want to do a busy-wait like you describe.
I found this answer here and I'm using it like this.
Code from my Library:
$.fn.customContextMenu = function(callBack){
$(this).each(function(){
$(this).bind("contextmenu",function(e){
e.preventDefault();
callBack();
});
});
}
Code from my page's script:
$("#newmagazine").customContextMenu(function(){
alert("some code");
});
Well, it actually looks like the warning is telling you what to do.
As part of sklearn.pipeline
stages' uniform interfaces, as a rule of thumb:
when you see X
, it should be an np.array
with two dimensions
when you see y
, it should be an np.array
with a single dimension.
Here, therefore, you should consider the following:
temp = [1,2,3,4,5,5,6,....................,7]
# This makes it into a 2d array
temp = np.array(temp).reshape((len(temp), 1))
temp = scaler.transform(temp)
I had a similar problem where I needed to only show a value from another Excel cell if the font was black. I created this function: `Option Explicit
Function blackFont(r As Range) As Boolean If r.Font.Color = 0 Then blackFont = True Else blackFont = False End If
End Function `
In my cell I have this formula:
=IF(blackFont(Y51),Y51," ")
This worked well for me to test for a black font and only show the value in the Y51 cell if it had a black font.
Continuing with JoelAnair's answer:
For more robustness, use as follows:
var el = document.getElementById('targetFrame');
if(el.contentWindow)
{
el.contentWindow.targetFunction();
}
else if(el.contentDocument)
{
el.contentDocument.targetFunction();
}
Workd like charm :)
Your description is a little bit strange because the GlassFish server can even start if port 1527 is occupied, because the Java Derby database is a separate java process. So one option could be to just ignore the message in case that the real GlassFish server is indeed starting correctly (NetBeans displays the output for the GlassFish server and the Derby server in different tabs).
Nevertheless you can try to disable starting the registered Derby server for your GlassFish instance.
Make sure that the Derby server is shut down, it can even still run if you have closed NetBeans. If you are not sure kill every java process via the task manager and restart NetBeans.
Right-click your GlassFish instance in the Services tab and choose Properties.
If instead the real problem is that either port 8080 or 443 (if you activated the HTTPS listener) is in use (which would really prevent GlassFish from starting), you have to find out which application is using this port (maybe Tomcat or something similar) and shut it down.
The error message
'Could not start GlassFish Server 4.1: HTTP or HTTPS listener port is occupied while server is not running'
just points a little bit more in this direction...
For the cut(1)
man page:
Use one, and only one of -b, -c or -f. Each LIST is made up of one range, or many ranges separated by commas. Selected input is written in the same order that it is read, and is written exactly once.
It reaches field 1 first, so that is printed, followed by field 2.
Use awk
instead:
awk '{ print $2 " " $1}' file.txt
You can also split a string at every n-th character and put them each, in each index of a List :
Here I made a list of Strings named Sequence :
List < String > Sequence
Then I'm basically splitting the String "KILOSO" by every 2 words. So 'KI' 'LO' 'SO' would be incorporate in separate index of the List called Sequence.
String S = KILOSO
Sequence = Arrays.asList(S.split("(?<=\G..)"));
So when I'm doing :
System.out.print(Sequence)
It should print :
[KI, LO, SO]
to verify I can write :
System.out.print(Sequence.get(1))
it will print :
LO
For Swift 3.0

EDIT: I just realized you want to filter details
, which is an array of hashes. In that case you could do
details.reject { |item| item[:qty].empty? }
The inner data structure itself is not an Array, but a Hash. You can also use select
here, but the block is given the key and value in this case:
irb(main):001:0> h = {:sku=>"507772-B21", :desc=>"HP 1TB 3G SATA 7.2K RPM LFF (3 .", :qty=>"", :qty2=>"1", :price=>"5,204.34 P"}
irb(main):002:0> h.select { |key, value| !value.empty? }
=> {:sku=>"507772-B21", :desc=>"HP 1TB 3G SATA 7.2K RPM LFF (3 .",
:qty2=>"1", :price=>"5,204.34 P"}
Or using reject
, which is the inverse of select
(excludes all items for which the given condition holds):
h.reject { |key, value| value.empty? }
Note that this is Ruby 1.9. If you have to maintain compatibility with 1.8, you could do:
Hash[h.reject { |key, value| value.empty? }]
After formatting the previous answer to my own code, I have found an efficient way to copy all necessary data if you are attempting to paste the values returned via AutoFilter
to a separate sheet.
With .Range("A1:A" & LastRow)
.Autofilter Field:=1, Criteria1:="=*" & strSearch & "*"
.Offset(1,0).SpecialCells(xlCellTypeVisible).Cells.Copy
Sheets("Sheet2").activate
DestinationRange.PasteSpecial
End With
In this block, the AutoFilter
finds all of the rows that contain the value of strSearch
and filters out all of the other values. It then copies the cells (using offset in case there is a header), opens the destination sheet and pastes the values to the specified range on the destination sheet.
Here's how I do it:
Code:
let fs = require('fs');
let path = require('path');
let myController = (req, res) => {
let filename = 'myFile.ext';
let absPath = path.join(__dirname, '/my_files/', filename);
let relPath = path.join('./my_files', filename); // path relative to server root
fs.writeFile(relPath, 'File content', (err) => {
if (err) {
console.log(err);
}
res.download(absPath, (err) => {
if (err) {
console.log(err);
}
fs.unlink(relPath, (err) => {
if (err) {
console.log(err);
}
console.log('FILE [' + filename + '] REMOVED!');
});
});
});
};

HTTP status code 500 usually means that the webserver code has crashed. You need to determine the status code beforehand using HttpURLConnection#getResponseCode()
and in case of errors, read the HttpURLConnection#getErrorStream()
instead. It may namely contain information about the problem.
If the host has blocked you, you would rather have gotten a 4nn status code like 401 or 403.
window.open is a method; you can open new window, and can customize it. window.location.href is just a property of the current window.
You are getting those errors because opencv
and cv2
are not the python package names.
These are both included as part of the opencv-python
package available to install from pip.
If you are using python 2 you can install with pip:
pip install opencv-python
Or use the equivilent for python 3:
pip3 install opencv-python
After running the appropriate pip command your package should be available to use from python.
From other member and my problem:
Camera Rotation issue depend on different Devices and certain Version.
Version 1.6: to fix the Rotation Issue, and it is good for most of devices
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT)
{
p.set("orientation", "portrait");
p.set("rotation",90);
}
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)
{
p.set("orientation", "landscape");
p.set("rotation", 90);
}
Version 2.1: depend on kind of devices, for example, Cannt fix the issue with XPeria X10, but it is good for X8, and Mini
Camera.Parameters parameters = camera.getParameters();
parameters.set("orientation", "portrait");
camera.setParameters(parameters);
Version 2.2: not for all devices
camera.setDisplayOrientation(90);
You can use isset() without losing the concatenation:
//snip
$str = 'something'
. ( isset($output['alternate_title']) ? $output['alternate_title'] : '' )
. ( isset($output['access_info']) ? $output['access_info'] : '' )
. //etc.
You could also write a function to return the string if it is set - this probably isn't very efficient:
function getIfSet(& $var) {
if (isset($var)) {
return $var;
}
return null;
}
$str = getIfSet($output['alternate_title']) . getIfSet($output['access_info']) //etc
You won't get a notice because the variable is passed by reference.
Open a terminal and take a look at:
/Applications/Python 3.6/Install Certificates.command

You can't, and you shouldn't.
Every other approach / alternative will only cause really bad user engagement.
That's my opinion.
The first approach is building separate Django and React apps. Django will be responsible for serving the API built using Django REST framework and React will consume these APIs using the Axios client or the browser's fetch API. You'll need to have two servers, both in development and production, one for Django(REST API) and the other for React (to serve static files).
The second approach is different the frontend and backend apps will be coupled. Basically you'll use Django to both serve the React frontend and to expose the REST API. So you'll need to integrate React and Webpack with Django, these are the steps that you can follow to do that
First generate your Django project then inside this project directory generate your React application using the React CLI
For Django project install django-webpack-loader with pip:
pip install django-webpack-loader
Next add the app to installed apps and configure it in settings.py
by adding the following object
WEBPACK_LOADER = {
'DEFAULT': {
'BUNDLE_DIR_NAME': '',
'STATS_FILE': os.path.join(BASE_DIR, 'webpack-stats.json'),
}
}
Then add a Django template that will be used to mount the React application and will be served by Django
{ % load render_bundle from webpack_loader % }
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width" />
<title>Django + React </title>
</head>
<body>
<div id="root">
This is where React will be mounted
</div>
{ % render_bundle 'main' % }
</body>
</html>
Then add an URL in urls.py
to serve this template
from django.conf.urls import url
from django.contrib import admin
from django.views.generic import TemplateView
urlpatterns = [
url(r'^', TemplateView.as_view(template_name="main.html")),
]
If you start both the Django and React servers at this point you'll get a Django error saying the webpack-stats.json
doesn't exist. So next you need to make your React application able to generate the stats file.
Go ahead and navigate inside your React app then install webpack-bundle-tracker
npm install webpack-bundle-tracker --save
Then eject your Webpack configuration and go to config/webpack.config.dev.js
then add
var BundleTracker = require('webpack-bundle-tracker');
//...
module.exports = {
plugins: [
new BundleTracker({path: "../", filename: 'webpack-stats.json'}),
]
}
This add BundleTracker plugin to Webpack and instruct it to generate webpack-stats.json
in the parent folder.
Make sure also to do the same in config/webpack.config.prod.js
for production.
Now if you re-run your React server the webpack-stats.json
will be generated and Django will be able to consume it to find information about the Webpack bundles generated by React dev server.
There are some other things to. You can find more information from this tutorial.
a += b
is in this case the same as
a = a + b
In this case cnt += 1 means that cnt is increased by one.
Note that the code you pasted will loop indefinitely if cnt > 0 and len(aStr) > 1.
Edit: quote Carl Meyer: ``[..] the answer is misleadingly mostly correct. There is a subtle but very significant difference between + and +=, see Bastien's answer.''.
Try this instead ...
i=0
x="abc"
while i<len(x) :
print(x[i],end=" ")
print(i)
i+=1
You can set tag of the button and access it from sender in action
[btnHome addTarget:self action:@selector(btnMenuClicked:) forControlEvents:UIControlEventTouchUpInside];
btnHome.userInteractionEnabled = YES;
btnHome.tag = 123;
In the called function
-(void)btnMenuClicked:(id)sender
{
[sender tag];
if ([sender tag] == 123) {
// Do Anything
}
}

Alright so I know this answer is old, but I found out how to do this for version 3.1.4. So for me this error occurs whenever I put in a new item into the hierarchy, so I knew I needed a solution. After tinkering around for a little bit I found how to do it by following these steps:
Provided that that method still works, after step two you should see squiggly lines going horizontally across where the item is, and after step three, both horizontally and vertically. After step three, the error will go away!
I think Django docs explicitly mention that if the intent is to start from an empty DB again (which seems to be OP's intent), then just drop and re-create the database and re-run migrate
(instead of using flush
):
If you would rather start from an empty database and re-run all migrations, you should drop and recreate the database and then run migrate instead.
So for OP's case, we just need to:
python manage.py migrate
There are two ways to write case statements, you seem to be using a combination of the two
case a.updatedDate
when 1760 then 'Entered on' + a.updatedDate
when 1710 then 'Viewed on' + a.updatedDate
else 'Last Updated on' + a.updateDate
end
or
case
when a.updatedDate = 1760 then 'Entered on' + a.updatedDate
when a.updatedDate = 1710 then 'Viewed on' + a.updatedDate
else 'Last Updated on' + a.updateDate
end
are equivalent. They may not work because you may need to convert date types to varchars to append them to other varchars.
A simple regex that will match, but I wouldn't recommend for validation of any sort is this:
([A-Fa-f0-9]{1,4}::?){1,7}[A-Fa-f0-9]{1,4}
Note this matches compression anywhere in the address, though it won't match the loopback address ::1. I find this a reasonable compromise in order to keep the regex simple.
I successfully use this in iTerm2 smart selection rules to quad-click IPv6 addresses.
This will give you the count per month for 2012;
SELECT MONTH(ARR_DATE) MONTH, COUNT(*) COUNT
FROM table_emp
WHERE YEAR(arr_date)=2012
GROUP BY MONTH(ARR_DATE);

callJavaScript(mBrowser, "alert", 1, true, "abc");
//javascript:try{alert(1,true,'abc')}catch(error){console.error(error.message);}
Note that objects will not be passed correctly - but you can serialize them before passing as an argument.
Also I've changed where the error goes, I've diverted it to the console log which can be listened by:
webView.setWebChromeClient(new CustomWebChromeClient());
and client
class CustomWebChromeClient extends WebChromeClient {
private static final String TAG = "CustomWebChromeClient";
@Override
public boolean onConsoleMessage(ConsoleMessage cm) {
Log.d(TAG, String.format("%s @ %d: %s", cm.message(),
cm.lineNumber(), cm.sourceId()));
return true;
}
}
Try this:
Dim i = Datagridview1.currentrow.index
textbox1.text = datagridview1.item(columnindex, i).value
It should work :)
On my AWS beanstalk server, I don't see $_SERVER['HTTPS'] variable. I do see $_SERVER['HTTP_X_FORWARDED_PROTO'] which can be either 'http' or 'https' so if you're hosting on AWS, use this:
if ($_SERVER['HTTP_HOST'] != 'localhost' and $_SERVER['HTTP_X_FORWARDED_PROTO'] != "https") {
$location = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
header('HTTP/1.1 301 Moved Permanently');
header('Location: ' . $location);
exit;
}
This can happen when invoking a method that doesn't exist.
Another reply to your questions (assuming you are on master and already did "git fetch origin" to make you repo aware about remote changes):
1) Commits on remote branch since when local branch was created:
git diff HEAD...origin/master
2) I assume by "working copy" you mean your local branch with some local commits that are not yet on remote. To see the differences of what you have on your local branch but that does not exist on remote branch run:
git diff origin/master...HEAD
3) See the answer by dbyrne.
You want to use single quotes:
if(c=='\0')
Double quotes (") are for strings, which are sequences of characters. Single quotes (') are for individual characters.
However, the end-of-line is represented by the newline character, which is '\n'.
Note that in both cases, the backslash is not part of the character, but just a way you represent special characters. Using backslashes you can represent various unprintable characters and also characters which would otherwise confuse the compiler.
Late resurrection.
Your query seems very similar to the one at page 259 of the book Pro JPA 2: Mastering the Java Persistence API, which in JPQL reads:
SELECT e
FROM Employee e
WHERE e IN (SELECT emp
FROM Project p JOIN p.employees emp
WHERE p.name = :project)
Using EclipseLink + H2 database, I couldn't get neither the book's JPQL nor the respective criteria working. For this particular problem I have found that if you reference the id directly instead of letting the persistence provider figure it out everything works as expected:
SELECT e
FROM Employee e
WHERE e.id IN (SELECT emp.id
FROM Project p JOIN p.employees emp
WHERE p.name = :project)
Finally, in order to address your question, here is an equivalent strongly typed criteria query that works:
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<Employee> c = cb.createQuery(Employee.class);
Root<Employee> emp = c.from(Employee.class);
Subquery<Integer> sq = c.subquery(Integer.class);
Root<Project> project = sq.from(Project.class);
Join<Project, Employee> sqEmp = project.join(Project_.employees);
sq.select(sqEmp.get(Employee_.id)).where(
cb.equal(project.get(Project_.name),
cb.parameter(String.class, "project")));
c.select(emp).where(
cb.in(emp.get(Employee_.id)).value(sq));
TypedQuery<Employee> q = em.createQuery(c);
q.setParameter("project", projectName); // projectName is a String
List<Employee> employees = q.getResultList();

Adding to Jim's elaborate answer:
Check the typing
module -- this module supports type hints as specified by PEP 484.
For example, the function below takes and returns values of type str
and is annotated as follows:
def greeting(name: str) -> str:
return 'Hello ' + name
The typing
module also supports:
just set position: fixed
to the footer element (instead of relative)
Note that you may need to also set a margin-bottom
to the main
element at least equal to the height of the footer element (e.g. margin-bottom: 1.5em;
) otherwise, in some circustances, the bottom area of the main content could be partially overlapped by your footer
The closest I can get to the answer is by adding an extension method into a System.Type
object. Not pretty, but still interesting.
public static class Foo
{
public static void Bar()
{
var now = DateTime.Now;
var tomorrow = typeof(DateTime).Tomorrow();
}
public static DateTime Tomorrow(this System.Type type)
{
if (type == typeof(DateTime)) {
return DateTime.Now.AddDays(1);
} else {
throw new InvalidOperationException();
}
}
}
Otherwise, IMO Andrew and ShuggyCoUk has a better implementation.
SELECT *
FROM A.tableA JOIN B.tableB
or
SELECT *
FROM A.tableA JOIN B.tableB
ON A.tableA.id = B.tableB.a_id;
If you donot like boost and c++17, the google c++ lib Abseil is another method to realize that. absl::optional is just like std::optional.
#include <absl/types/optional.h>
class MyClass
{
void SomeMethod();
absl::optional<char> mCharacter;
absl::optional<double> mDecimal;
};
void MyClass::SomeMethod()
{
if (mCharacter)
{
// do something with mCharacter.
}
if (!mDecimal)
{
// define mDecimal.
}
}

When you are done with a connection, just call connection.release()
and the connection will return to the pool, ready to be used again by someone else.
var mysql = require('mysql');
var pool = mysql.createPool(...);
pool.getConnection(function(err, connection) {
// Use the connection
connection.query('SELECT something FROM sometable', function (error, results, fields) {
// And done with the connection.
connection.release();
// Handle error after the release.
if (error) throw error;
// Don't use the connection here, it has been returned to the pool.
});
});
If you would like to close the connection and remove it from the pool, use connection.destroy()
instead. The pool will create a new connection the next time one is needed.

The importance of the double quotes is worth emphasizing. Suppose an argument contains whitespace.
Code:
#!/bin/bash
printf 'arguments:%s\n' "$@"
declare -a arrayGOOD=( "$@" )
declare -a arrayBAAD=( $@ )
printf '\n%s:\n' arrayGOOD
declare -p arrayGOOD
arrayGOODlength=${#arrayGOOD[@]}
for (( i=1; i<${arrayGOODlength}+1; i++ ));
do
echo "${arrayGOOD[$i-1]}"
done
printf '\n%s:\n' arrayBAAD
declare -p arrayBAAD
arrayBAADlength=${#arrayBAAD[@]}
for (( i=1; i<${arrayBAADlength}+1; i++ ));
do
echo "${arrayBAAD[$i-1]}"
done
Output:
> ./bash-array-practice.sh 'The dog ate the "flea" -- and ' the mouse.
arguments:The dog ate the "flea" -- and

arguments:mouse.
arrayGOOD:
declare -a arrayGOOD='([0]="The dog ate the \"flea\" -- and " [1]="the" [2]="mouse.")'
The dog ate the "flea" -- and

With ECMAScript 2015 you can do it directly in object declaration using bracket notation:
var obj = {
[key]: value
}
Where key
can be any sort of expression (e.g. a variable) returning a value:
var obj = {
['hello']: 'World',
[x + 2]: 42,
[someObject.getId()]: someVar
}
I am late to this question, but here is what you can do with MySQL (as I use MySQL). I am sharing my observations here:
1) SELECT COUNT(*) AS TOTAL_ROWS FROM <TABLE_NAME>
Result
Row Count: 508534
Console output: Affected rows: 0 Found rows: 1 Warnings: 0 Duration for 1 query: 0.125 sec.
Takes a while for a table with large number of rows, but the row count is very exact.
2) SHOW TABLE STATUS or SHOW TABLE STATUS WHERE NAME="<TABLE_NAME>"
Result
Row count: 511235
Console output: Affected rows: 0 Found rows: 1 Warnings: 0 Duration for 1 query: 0.250 sec
Summary: Row count is not exact.
3) SELECT * FROM information_schema.tables WHERE table_schema = DATABASE();
Result
Row count: 507806
Console output: Affected rows: 0 Found rows: 48 Warnings: 0 Duration for 1 query: 1.701 sec.
Row count is not exact.
I am not a MySQL or database expert, but I have found that for very large tables, you can use option 2 or 3 and get a 'fair idea' of how many rows are present.
I needed to get these row counts for displaying some stats on the UI. With the above queries, I knew that the total rows were more than 500,000, so I came up with showing stats like "More than 500,000 rows" without showing exact number of rows.
Maybe I have not really answered the OP's question, but I am sharing what I did in a situation where such statistics were needed. In my case, showing the approximate rows was acceptable and so the above worked for me.
You could also put non-breaking spaces (&nbsp;) in lieu of the spaces so that they're forced to stay together.
How do I wrap this line of text
- asked by Peter 2 days ago
A very simple, non-technical rule-of-thumb would be that clustered indexes are usually used for your primary key (or, at least, a unique column) and that non-clustered are used for other situations (maybe a foreign key). Indeed, SQL Server will by default create a clustered index on your primary key column(s). As you will have learnt, the clustered index relates to the way data is physically sorted on disk, which means it's a good all-round choice for most situations.
You cannot add AM / PM to a TimeSpan
. You'll anyway have to associate the TimaSpan
value with DateTime
if you want to display the time in 12-hour clock format.
TimeSpan
is not intended to use with a 12-hour clock format, because we are talking about a time interval here.
As it says in the documentation;
A
TimeSpan
object represents a time interval (duration of time or elapsed time) that is measured as a positive or negative number of days, hours, minutes, seconds, and fractions of a second. TheTimeSpan
structure can also be used to represent the time of day, but only if the time is unrelated to a particular date. Otherwise, theDateTime
orDateTimeOffset
structure should be used instead.
Also Microsoft Docs describes as follows;
A
TimeSpan
value can be represented as[-]d.hh:mm:ss.ff
, where the optional minus sign indicates a negative time interval, thed
component is days,hh
is hours as measured on a 24-hour clock,mm
is minutes,ss
is seconds, andff
is fractions of a second.
So in this case, you can display using AM/PM as follows.
TimeSpan storedTime = new TimeSpan(03,00,00);
string displayValue = new DateTime().Add(storedTime).ToString("hh:mm tt");
Side note :
Also should note that the TimeOfDay property of DateTime
is a TimeSpan
, where it represents
a time interval that represents the fraction of the day that has elapsed since midnight.
For anyone struggling with this, I tried the mentioned options without success. Turns out all I needed to do was just quit and relaunch Xcode. Simple things can be annoying sometimes.
Find a better use for myself: I usually test if a variant is empty, and all of the above methods fail with the test. I found that you can actually set a variant to empty:
Dim aTable As Variant
If IsEmpty(aTable) Then
'This is true
End If
ReDim aTable(2)
If IsEmpty(aTable) Then
'This is False
End If
ReDim aTable(2)
aTable = Empty
If IsEmpty(aTable) Then
'This is true
End If
ReDim aTable(2)
Erase aTable
If IsEmpty(aTable) Then
'This is False
End If
this way i get the behaviour i want
In addition to what Tichodroma said, you might end up using this syntax:
outputString=$(python myPythonScript arg1 arg2 arg3)
You can also use the Cookies API and do:
browser.cookies.set({
url: 'example.com',
name: 'HelloWorld',
value: 'HelloWorld',
expirationDate: myDate
}
In Python shape()
is use in pandas to give number of row/column:
Number of rows is given by:
train = pd.read_csv('fine_name') //load the data
train.shape[0]
Number of columns is given by
train.shape[1]
header('Location: .');
seems to refresh the page in Chrome, Firefox, Edge, and Internet Explorer 11.
int elem = 42;
std::vector<int> v;
v.push_back(elem);
if(std::find(v.begin(), v.end(), elem) != v.end())
{
//elem exists in the vector
}
You can either user STR_TO_DATE function and pass your own date parameters based on the format you have posted :
select * from hockey_stats where game_date
between STR_TO_DATE('11/3/2012 00:00:00', '%c/%e/%Y %H:%i:%s')
and STR_TO_DATE('11/5/2012 23:59:00', '%c/%e/%Y %H:%i:%s')
order by game_date desc;
Or just use the format which MySQL handles dates YYYY:MM:DD HH:mm:SS and have the query as
select * from hockey_stats where game_date between '2012-03-11 00:00:00' and'2012-05-11 23:59:00' order by game_date desc;
This wrapper method will help :
private static JSONObject merge(JSONObject... jsonObjects) throws JSONException {
JSONObject jsonObject = new JSONObject();
for(JSONObject temp : jsonObjects){
Iterator<String> keys = temp.keys();
while(keys.hasNext()){
String key = keys.next();
jsonObject.put(key, temp.get(key));
}
}
return jsonObject;
}
That query is failing and returning false

Extra Tips:
Multiple "nots", input that is NOT hidden and NOT disabled:
:not([type="hidden"]):not([disabled])
Also did you know you can do this:
node.parentNode.querySelectorAll('div');
This is equivelent to jQuery's:
$(node).parent().find('div');
Which will effectively find all divs in "node" and below recursively, HOT DAMN!
The accepted solution is probably the best bet for your purposes, but to actually answer the question in the subject line:
In my app, I have to get the path from URIs and get the URI from paths. The former:
/**
* Gets the corresponding path to a file from the given content:// URI
* @param selectedVideoUri The content:// URI to find the file path from
* @param contentResolver The content resolver to use to perform the query.
* @return the file path as a string
*/
private String getFilePathFromContentUri(Uri selectedVideoUri,
ContentResolver contentResolver) {
String filePath;
String[] filePathColumn = {MediaColumns.DATA};
Cursor cursor = contentResolver.query(selectedVideoUri, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
filePath = cursor.getString(columnIndex);
cursor.close();
return filePath;
}
The latter (which I do for videos, but can also be used for Audio or Files or other types of stored content by substituting MediaStore.Audio (etc) for MediaStore.Video):
/**
* Gets the MediaStore video ID of a given file on external storage
* @param filePath The path (on external storage) of the file to resolve the ID of
* @param contentResolver The content resolver to use to perform the query.
* @return the video ID as a long
*/
private long getVideoIdFromFilePath(String filePath,
ContentResolver contentResolver) {
long videoId;
Log.d(TAG,"Loading file " + filePath);
// This returns us content://media/external/videos/media (or something like that)
// I pass in "external" because that's the MediaStore's name for the external
// storage on my device (the other possibility is "internal")
Uri videosUri = MediaStore.Video.Media.getContentUri("external");
Log.d(TAG,"videosUri = " + videosUri.toString());
String[] projection = {MediaStore.Video.VideoColumns._ID};
// TODO This will break if we have no matching item in the MediaStore.
Cursor cursor = contentResolver.query(videosUri, projection, MediaStore.Video.VideoColumns.DATA + " LIKE ?", new String[] { filePath }, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(projection[0]);
videoId = cursor.getLong(columnIndex);
Log.d(TAG,"Video ID is " + videoId);
cursor.close();
return videoId;
}
Basically, the DATA
column of MediaStore
(or whichever sub-section of it you're querying) stores the file path, so you use that info to look it up.

Keep in mind that the %CLASSPATH%
environment variable is ignored when you use java/javac in combination with one of the -cp
, -classpath
or -jar
arguments. It is also ignored in an IDE like Netbeans/Eclipse/IntelliJ/etc. It is only been used when you use java/javac without any of the above mentioned arguments.
In case of JAR files, the classpath is to be defined as class-path
entry in the manifest.mf file. It can be defined semicolon separated and relative to the JAR file's root.
In case of an IDE, you have the so-called 'build path' which is basically the classpath which is used at both compiletime and runtime. To add external libraries you usually drop the JAR file in a (either precreated by IDE or custom created) lib
folder of the project which is added to the project's build path.
You have to tell your compiler where is the include directory. Something like this:
gcc -I/usr/lib/jvm/jdk1.7.0_07/include
But it depends on your makefile.
How about something like this?
<input name="myvalue" type="text" onfocus="if(this.value=='enter value')this.value='';" onblur="if(this.value=='')this.value='enter value';">
This will clear upon focusing the first time, but then won't clear on subsequent focuses after the user enters their value, when left blank it restores the given value.
In MacOS Catalina 10.15.5 the .npmrc
file path can be found at
/Users/<user-name>/.npmrc
Open in it in (for first time users, create a new file) any editor and copy-paste your token. Save it.
You are ready to go.
Note:
As mentioned by @oligofren, the command npm config ls -l
will npm configurations. You will get the .npmrc file from config parameter userconfig
The use
keyword is for aliasing in PHP and it does not import the classes. This really helps
1) When you have classes with same name in different namespaces
2) Avoid using really long class name over and over again.
Eager Loading When you are sure that want to get multiple entities at a time, for example you have to show user, and user details at the same page, then you should go with eager loading. Eager loading makes single hit on database and load the related entities.
Lazy loading When you have to show users only at the page, and by clicking on users you need to show user details then you need to go with lazy loading. Lazy loading make multiple hits, to get load the related entities when you bind/iterate related entities.
Avro is a row-based storage format for Hadoop.
Parquet is a column-based storage format for Hadoop.
If your use case typically scans or retrieves all of the fields in a row in each query, Avro is usually the best choice.
If your dataset has many columns, and your use case typically involves working with a subset of those columns rather than entire records, Parquet is optimized for that kind of work.

You could use the CSS calc
parameter to calculate the height dynamically like so:
.dynamic-height {_x000D_
color: #000;_x000D_
font-size: 12px;_x000D_
margin-top: calc(100% - 10px);_x000D_
text-align: left;_x000D_
}
_x000D_
<div class='dynamic-height'>_x000D_
<p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem.</p>_x000D_
</div>

You can use git rebase --interactive
, using the edit
command on the commit you want to amend.
You can get this exception by just a simple/dumb mistake, by (for example) accidentally calling finish()
after having displayed an AlertDialog
, if you miss a break call statement in a switch statement...
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.new_button:
openMyAlertDialog();
break; <-- If you forget this the finish() method below
will be called while the dialog is showing!
case R.id.exit_button:
finish();
break;
}
}
The finish()
method will close the Activity
, but the AlertDialog
is still displaying!
So when you're staring intently at the code, looking for bad threading issues or complex coding and such, don't lose sight of the forest for the trees. Sometimes it can be just something as simple and dumb as a missing break statement. :)
Anyone can define "token_type" as an OAuth 2.0 extension, but currently "bearer" token type is the most common one.
https://tools.ietf.org/html/rfc6750
Basically that's what Facebook is using. Their implementation is a bit behind from the latest spec though.
If you want to be more secure than Facebook (or as secure as OAuth 1.0 which has "signature"), you can use "mac" token type.
However, it will be hard way since the mac spec is still changing rapidly.
Based in this implementation with Node.js of JWT with refresh token:
1) In this case they use a uid and it's not a JWT. When they refresh the token they send the refresh token and the user. If you implement it as a JWT, you don't need to send the user, because it would inside the JWT.
2) They implement this in a separated document (table). It has sense to me because a user can be logged in in different client applications and it could have a refresh token by app. If the user lose a device with one app installed, the refresh token of that device could be invalidated without affecting the other logged in devices.
3) In this implementation it response to the log in method with both, access token and refresh token. It seams correct to me.
Here is how you can do it with for-in
loop.
var children = element.childNodes;
for(child in children){
console.log(children[child]);
}
Even after installing SP3 to SQL Server 2008 Enterprise this is still an "issue." Ctrl+Shift+R like everyone has been saying solved this problem for me.
Java doesn't support default parameters. You will need to have two constructors to do what you want.
An alternative if there are lots of possible values with defaults is to use the Builder pattern, whereby you use a helper object with setters.
e.g.
public class Foo {
private final String param1;
private final String param2;
private Foo(Builder builder) {
this.param1 = builder.param1;
this.param2 = builder.param2;
}
public static class Builder {
private String param1 = "defaultForParam1";
private String param2 = "defaultForParam2";
public Builder param1(String param1) {
this.param1 = param1;
return this;
}
public Builder param2(String param1) {
this.param2 = param2;
return this;
}
public Foo build() {
return new Foo(this);
}
}
}
which allows you to say:
Foo myFoo = new Foo.Builder().param1("myvalue").build();
which will have a default value for param2
.
In vue js :
self.$refs.inputFile.value = ''

You might want to look at csounds, also. It has several API's, including Python. It might be able to interact with an A-D interface and gather sound samples.
If the plugin you want to install is not listed in the Plugins Admin, you may still install it manually. The plugin (in the DLL form) should be placed in the plugins subfolder of the Notepad++ Install Folder, under the subfolder with the same name of plugin binary name without file extension.
For example, if the plugin you want to install named myAwesomePlugin.dll, you should install it with the following path:
%PROGRAMFILES(x86)%\Notepad++\plugins\myAwesomePlugin\myAwesomePlugin.dll
or
%PROGRAMFILES%\Notepad++\plugins\myAwesomePlugin\myAwesomePlugin.dll
Once you installed the plugin, you can use (and you may configure) it via the menu “Plugins”.
Restart the Notepad++ after putting the plugin
This is similiarly to @RobMcAfee except that I use magic number instead of 2 dimensional array.
int rand7() {
int m = 1203068;
int r = (m >> (rand5() - 1) * 5 + rand5() - 1) & 7;
return (r > 0) ? r : rand7();
}
There's also solution for Node JS app. CORS Anywhere is a NodeJS proxy which adds CORS headers to the proxied request.
The url to proxy is literally taken from the path, validated and proxied. The protocol part of the proxied URI is optional, and defaults to "http". If port 443 is specified, the protocol defaults to "https".
This package does not put any restrictions on the http methods or headers, except for cookies. Requesting user credentials is disallowed. The app can be configured to require a header for proxying a request, for example to avoid a direct visit from the browser. https://robwu.nl/cors-anywhere.html
this works for me, sudo apt-get install libx11-dev
From the Active Record docs:
$this->db->where_in();
Generates a WHERE field IN ('item', 'item') SQL query joined with AND if appropriate
$names = array('Frank', 'Todd', 'James');
$this->db->where_in('username', $names);
// Produces: WHERE username IN ('Frank', 'Todd', 'James')
