Why don't you introduce a service layer. then your controller will be lean and more readable, then your all controller functions will be pure actions. you can decompose business logic as you much as you need within service layer . code reusability is hight . no impact on models and repositories.
your can try this :
SELECT columnName1, CAST(columnName2 AS SIGNED ) FROM tableName
What was asked for was to set:
the 'default', not some other color profile, and
'for all vim sessions', not simply for the current user.
The default colorscheme, "for all vim sessions", is not set simply by adding a line to your ~/.vimrc
, as all of the other answers here say, nor is the default set without the word 'default' being there.
So all of the other answers here, so far, get both of these wrong. (lol, how did that happen?)
The correct answer is:
Add a line to your system vim setup file in /etc/vim/
that says
colorscheme default
or using the abbreviation
colo default
but not capitalized as
colo Default
(I suggest using the full, un-abbreviated term 'colorscheme', so that when you look at this years later you'll be able to more easily figure out what that darn thing does. I would also put a comment above it like "Use default colors for vim"
.)
To append that correctly, first look at your /etc/vim/vimrc
file.
At the bottom of mine, I see these lines which include /etc/vim/vimrc.local
:
" Source a global configuration file if available
if filereadable("/etc/vim/vimrc.local")
source /etc/vim/vimrc.local
endif
So you can append this line to either of these two files.
I think the best solution is to append your line to /etc/vim/vimrc.local
like this:
colorscheme default
You can easily do that in bash with this line:
$ echo -e "\"Use default colors for vim:\ncolorscheme default" \
| sudo tee -a /etc/vim/vimrc.local
#
# NOTE: This doesn't work:
#
# $ sudo echo 'colorscheme default' >> /etc/vim/vimrc.local
#
# It's the same general idea, and simpler, but because sudo doesn't
# know how to handle pipes, it fails with a `Permission denied` error.
Also check that you have permission to globally read this file:
sudo chmod 644 /etc/vim/vimrc.local
With $ tail /etc/vim/vimrc.local
you should now see these lines:
"Use default colors for vim:
colorscheme default
I came into this issue when I copy my local repository.
sudo cp -r original_repo backup_repo
cd backup_repo
git status
fatal: Not a git repository (or any parent up to mount point /data)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
I've try git init
as some answer suggested, but it doesn't work.
sudo git init
Reinitialized existing Git repository in /data/HQ/SC_Educations/hq_htdocs/HQ_Educations_bak/.git/
I solved it by change the owner of the repo
sudo chown -R www:www ../backup_repo
git status

If you are doing a full round-trip post-back, you can just make the button disappear. If there are validation errors, the button will be visible again upon reload of the page.
First set add a style to your button:
<h:commandButton id="SaveBtn" value="Save"
styleClass="hideOnClick"
actionListener="#{someBean.saveAction()}"/>
Then make it hide when clicked.
$(document).ready(function() {
$(".hideOnClick").click(function(e) {
$(e.toElement).hide();
});
});
You actually can't manually "free" memory in C, in the sense that the memory is released from the process back to the OS ... when you call malloc()
, the underlying libc-runtime will request from the OS a memory region. On Linux, this may be done though a relatively "heavy" call like mmap()
. Once this memory region is mapped to your program, there is a linked-list setup called the "free store" that manages this allocated memory region. When you call malloc()
, it quickly looks though the free-store for a free block of memory at the size requested. It then adjusts the linked list to reflect that there has been a chunk of memory taken out of the originally allocated memory pool. When you call free()
the memory block is placed back in the free-store as a linked-list node that indicates its an available chunk of memory.
If you request more memory than what is located in the free-store, the libc-runtime will again request more memory from the OS up to the limit of the OS's ability to allocate memory for running processes. When you free memory though, it's not returned back to the OS ... it's typically recycled back into the free-store where it can be used again by another call to malloc()
. Thus, if you make a lot of calls to malloc()
and free()
with varying memory size requests, it could, in theory, cause a condition called "memory fragmentation", where there is enough space in the free-store to allocate your requested memory block, but not enough contiguous space for the size of the block you've requested. Thus the call to malloc()
fails, and you're effectively "out-of-memory" even though there may be plenty of memory available as a total amount of bytes in the free-store.

If you have dates as a string, it might be easier to do it using pandas' Timestamp
import pandas as pd
df = pd.Timestamp("2019-04-12")
print(df.dayofweek, df.weekday_name)
Output:

I see the question has already been answered, but still want to add my 2 cents for the same.
I have also faced similar scenario in which I have to test the execution times for several approaches and hence written a small script, which calls timeit on all functions written in it.

Hope it will help you and others.

In Xaml verify that there are no Missing Parent Nodes or incorrect nodes in the defined areas.
For example
There is no proper parent for the ItemsPanelTemplate
child node below:
<ItemsControl ItemsSource="{Binding TimeSpanChoices}">
<ItemsPanelTemplate>
<UniformGrid Rows="1" />
</ItemsPanelTemplate>
...
</ItemsControl>
<ItemsControl ItemsSource="{Binding TimeSpanChoices}">
<ItemsControl.ItemsPanel> <!-- I am the missing parent! -->
<ItemsPanelTemplate>
<UniformGrid Rows="1" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
...
</ItemsControl>
There is a proper parent node of <ItemsControl.ItemsPanel>
provided^^^.
Basically sudo expects, an executable (command) to follow & you are providing with a .
Hence the error.
Try this way $ sudo setup.sh
To update entries other than appsettings
, simply use XmlDocument
.
public static void UpdateAppConfig(string tagName, string attributeName, string value)
{
var doc = new XmlDocument();
doc.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
var tags = doc.GetElementsByTagName(tagName);
foreach (XmlNode item in tags)
{
var attribute = item.Attributes[attributeName];
if (!ReferenceEquals(null, attribute))
attribute.Value = value;
}
doc.Save(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
}
This is how you call it:
Utility.UpdateAppConfig("endpoint", "address", "http://localhost:19092/NotificationSvc/Notification.svc");
Utility.UpdateAppConfig("network", "host", "abc.com.au");
This method can be improved to cater for appSettings values as well.
For those of you who are popping up a new window to print from, and then automatically closing it after the user clicks "Print" or "Cancel" on the Chrome print preview, I used the following (thanks to the help from PaulVB's answer):
if (navigator.userAgent.toLowerCase().indexOf('chrome') > -1) {
var showPopup = false;
window.onbeforeunload = function () {
if (showPopup) {
return 'You must use the Cancel button to close the Print Preview window.\n';
} else {
showPopup = true;
}
}
window.print();
window.close();
} else {
window.print();
window.close();
}
I am debating if it would be a good idea to also filter by the version of Chrome...
First allow NULL on the parent table and set the default values to NULL. Next create the foreign key relationship. Afterwards, you can update the values to match accordingly
Just an observation about the markup The markup form in prior versions of HTML provided an anchor point. The markup forms in HTML5 using the id attribute, while mostly equivalent, require an element to identify, almost all of which are normally expected to contain content.
An empty span or div could be used, for instance, but this usage looks and smells degenerate.
One thought is to use the wbr element for this purpose. The wbr has an empty content model and simply declares that a line break is possible; this is still a slightly gratuitous use of a markup tag, but much less so than gratuitous document divisions or empty text spans.
This is because of your long project directory name, which gives you a very long CLASSPATH
altogether. Either you need to reduce jars added at CLASSPATH
(make sure removing unnecessary jars only) Or the best way is to reduce the project directory and import the project again. This will reduce the CLASSPATH
.
It worked for me.

What is the young generation?
The Young Generation is where all new objects are allocated and aged. When the young generation fills up, this causes a minor garbage collection. A young generation full of dead objects is collected very quickly. Some survived objects are aged and eventually move to the old generation.
What is the old generation?
The Old Generation is used to store long surviving objects. Typically, a threshold is set for young generation object and when that age is met, the object gets moved to the old generation. Eventually the old generation needs to be collected. This event is called a major garbage collection
What is the permanent generation?
The Permanent generation contains metadata required by the JVM to describe the classes and methods used in the application. The permanent generation is populated by the JVM at runtime based on classes in use by the application.
PermGen has been replaced with Metaspace since Java 8 release.
PermSize & MaxPermSize parameters will be ignored now
How does the three generations interact/relate to each other?
Image source & oracle technetwork tutorial article: http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/gc01/index.html
"The General Garbage Collection Process" in above article explains the interactions between them with many diagrams.
Have a look at summary diagram:
Maybe you can try the following without XPath
from simplified_scrapy.simplified_doc import SimplifiedDoc
html = '''
<html>
<body>
<div>
<h1>Example Domain</h1>
<p>This domain is for use in illustrative examples in documents. You may use this
domain in literature without prior coordination or asking for permission.</p>
<p><a href="https://www.iana.org/domains/example">More information...</a></p>
</div>
</body>
</html>
'''
# What XPath can do, so can it
doc = SimplifiedDoc(html)
# The result is the same as doc.getElementByTag('body').getElementByTag('div').getElementByTag('h1').text
print (doc.body.div.h1.text)
print (doc.div.h1.text)
print (doc.h1.text) # Shorter paths will be faster
print (doc.div.getChildren())
print (doc.div.getChildren('p'))
I don't think there is a more "angular way" to select an element. See, for instance, the way they are achieving this goal in the last example of this old documentation page:
{
template: '<div>' +
'<div class="title">{{title}}</div>' +
'<div class="body" ng-transclude></div>' +
'</div>',
link: function(scope, element, attrs) {
// Title element
var title = angular.element(element.children()[0]),
// ...
}
}
Thanks to @Birchlabs' comment, now it is tons easier with this special Mac-only DNS name available:
docker run -e DB_PORT=5432 -e DB_HOST=docker.for.mac.host.internal
From 17.12.0-cd-mac46, docker.for.mac.host.internal
should be used instead of docker.for.mac.localhost
. See release note for details.
@helmbert's answer well explains the issue. But Docker for Mac does not expose the bridge network, so I had to do this trick to workaround the limitation:
$ sudo ifconfig lo0 alias 10.200.10.1/24
Open /usr/local/var/postgres/pg_hba.conf
and add this line:
host all all 10.200.10.1/24 trust
Open /usr/local/var/postgres/postgresql.conf
and edit change listen_addresses
:
listen_addresses = '*'
Reload service and launch your container:
$ PGDATA=/usr/local/var/postgres pg_ctl reload
$ docker run -e DB_PORT=5432 -e DB_HOST=10.200.10.1 my_app
What this workaround does is basically same with @helmbert's answer, but uses an IP address that is attached to lo0
instead of docker0
network interface.
Quoting from wikipedia:
A pointer references a location in memory, and obtaining the value at the location a pointer refers to is known as dereferencing the pointer.
Dereferencing is done by applying the unary *
operator on the pointer.
int x = 5;
int * p; // pointer declaration
p = &x; // pointer assignment
*p = 7; // pointer dereferencing, example 1
int y = *p; // pointer dereferencing, example 2
"Dereferencing a NULL pointer" means performing *p
when the p
is NULL

Update: The code in this answer is for Super CSV 1.52. Updated code examples for Super CSV 2.4.0 can be found at the project website: http://super-csv.github.io/super-csv/index.html
The SuperCSV project directly supports the parsing and structured manipulation of CSV cells. From http://super-csv.github.io/super-csv/examples_reading.html you'll find e.g.
given a class
public class UserBean {
String username, password, street, town;
int zip;
public String getPassword() { return password; }
public String getStreet() { return street; }
public String getTown() { return town; }
public String getUsername() { return username; }
public int getZip() { return zip; }
public void setPassword(String password) { this.password = password; }
public void setStreet(String street) { this.street = street; }
public void setTown(String town) { this.town = town; }
public void setUsername(String username) { this.username = username; }
public void setZip(int zip) { this.zip = zip; }
}
and that you have a CSV file with a header. Let's assume the following content
username, password, date, zip, town
Klaus, qwexyKiks, 17/1/2007, 1111, New York
Oufu, bobilop, 10/10/2007, 4555, New York
You can then create an instance of the UserBean and populate it with values from the second line of the file with the following code
class ReadingObjects {
public static void main(String[] args) throws Exception{
ICsvBeanReader inFile = new CsvBeanReader(new FileReader("foo.csv"), CsvPreference.EXCEL_PREFERENCE);
try {
final String[] header = inFile.getCSVHeader(true);
UserBean user;
while( (user = inFile.read(UserBean.class, header, processors)) != null) {
System.out.println(user.getZip());
}
} finally {
inFile.close();
}
}
}
using the following "manipulation specification"
final CellProcessor[] processors = new CellProcessor[] {
new Unique(new StrMinMax(5, 20)),
new StrMinMax(8, 35),
new ParseDate("dd/MM/yyyy"),
new Optional(new ParseInt()),
null
};
There is not a way to directly get the version out, but there are two work-arounds that could be done.
The version could be stored in a resource string, and placed into the manifest by:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.somepackage"
android:versionName="@string/version" android:versionCode="20">
One could create a custom view, and place it into the XML. The view would use this to assign the name:
context.getPackageManager().getPackageInfo(context.getPackageName(), 0).versionName;
Either of these solutions would allow for placing the version name in XML. Unfortunately there isn't a nice simple solution, like android.R.string.version
or something like that.
Try to declare these functions as extern "C++"
if your compiler supports this, http://msdn.microsoft.com/en-us/library/s6y4zxec(VS.80).aspx
You can also use the ignore syntax instead of using (or better the 'as any') notation:
// @ts-ignore
$("div.printArea").printArea();
error_reporting(E_ALL ^ E_WARNING);
:)
You should change subject to "How to fix warning from date() in PHP"...
Just add the following rules to the parent element:
display: flex;
justify-content: center; /* align horizontal */
align-items: center; /* align vertical */
Here's a sample demo (Resize window to see the image align)
Browser support for Flexbox nowadays is quite good.
For cross-browser compatibility for display: flex
and align-items
, you can add the older flexbox syntax as well:
display: -webkit-box;
display: -webkit-flex;
display: -moz-box;
display: -ms-flexbox;
display: flex;
-webkit-flex-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;
This implementation:
do=true
while $do || conditions; do
do=false
# your code ...
done
It works with a read loop, too, skipping the first read:
do=true
while $do || read foo; do
do=false
# your code ...
echo $foo
done
Though all the answers on the page will return the desired result, they all have performance issues. Never perform calculations on fields in the WHERE
clause (including a DATE()
calculation) as that calculation must be performed on all rows in the table.
The BETWEEN ... AND
construct is inclusive for both border conditions, requiring one to specify the 23:59:59 syntax on the end date which itself has other issues (microsecond transactions, which I believe MySQL did not support in 2009 when the question was asked).
The proper way to query a MySQL timestamp
field for a particular day is to check for Greater-Than-Equals against the desired date, and Less-Than for the day after, with no hour specified.
WHERE datetime>='2009-10-20' AND datetime<'2009-10-21'
This is the fastest-performing, lowest-memory, least-resource intensive method, and additionally supports all MySQL features and corner-cases such as sub-second timestamp precision. Additionally, it is future proof.

I needed to start/stop background music in my application when first activity opens and closes or when any activity is paused by home button and then resumed from task manager. Pure playback stopping/resuming in Activity.onPause()
and Activity.onResume()
interrupted the music for a while, so I had to write the following code:
@Override
public void onResume() {
super.onResume();
// start playback here (if not playing already)
}
@Override
public void onPause() {
super.onPause();
ActivityManager manager = (ActivityManager) this.getSystemService(Activity.ACTIVITY_SERVICE);
List<ActivityManager.RunningTaskInfo> tasks = manager.getRunningTasks(Integer.MAX_VALUE);
boolean is_finishing = this.isFinishing();
boolean is_last = false;
boolean is_topmost = false;
for (ActivityManager.RunningTaskInfo task : tasks) {
if (task.topActivity.getPackageName().startsWith("cz.matelier.skolasmyku")) {
is_last = task.numRunning == 1;
is_topmost = task.topActivity.equals(this.getComponentName());
break;
}
}
if ((is_finishing && is_last) || (!is_finishing && is_topmost && !mIsStarting)) {
mIsStarting = false;
// stop playback here
}
}
which interrupts the playback only when application (all its activities) is closed or when home button is pressed. Unfortunatelly I didn't manage to change order of calls of onPause()
method of the starting activity and onResume()
of the started actvity when Activity.startActivity()
is called (or detect in onPause()
that activity is launching another activity other way) so this case have to be handled specially:
private boolean mIsStarting;
@Override
public void startActivity(Intent intent) {
mIsStarting = true;
super.startActivity(intent);
}
Another drawback is that this requires GET_TASKS
permission added to AndroidManifest.xml
:
<uses-permission
android:name="android.permission.GET_TASKS"/>
Modifying this code that it only reacts on home button press is straighforward.
To start the batch file at the start of your system, you can also use a registry key.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Here you can create a string. As name you can choose anything and the data is the full path to your file.
There is also the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
to run something at only the next start of your system.
install -d -m 0777 /your/dir
should give you what you want. Be aware that every user has the right to write add and delete files in that directory.

From React's documentation:
setState()
does not immediately mutatethis.state
but creates a pending state transition. Accessingthis.state
after calling this method can potentially return the existing value. There is no guarantee of synchronous operation of calls tosetState
and calls may be batched for performance gains.
If you want a function to be executed after the state change occurs, pass it in as a callback.
this.setState({value: event.target.value}, function () {
console.log(this.state.value);
});

of that
jFrame.getContentPane().setSize(800,400);
So I would advise you to use JPanel embedded in a JFrame and you draw on that JPanel. This would minimize your problem.
JFrame jf = new JFrame();
JPanel jp = new JPanel();
jp.setPreferredSize(new Dimension(400,800));// changed it to preferredSize, Thanks!
jf.getContentPane().add( jp );// adding to content pane will work here. Please read the comment bellow.
jf.pack();
I am reading this from Javadoc
The
JFrame
class is slightly incompatible withFrame
. Like all other JFC/Swing top-level containers, a JFrame contains aJRootPane
as its only child. The content pane provided by the root pane should, as a rule, contain all the non-menu components displayed by theJFrame
. This is different from the AWT Frame case. For example, to add a child to an AWT frame you'd write:
frame.add(child);
However using
JFrame
you need to add the child to theJFrame
's content pane instead:
frame.getContentPane().add(child);
"C:\Program Files\PuTTY\pscp.exe" -scp file.py server.com:
file.py
will be uploaded into your HOME
dir on remote server.
or when the remote server has a different user, use "C:\Program Files\PuTTY\pscp.exe" -l username -scp file.py server.com:
After connecting to the server pscp will ask for a password.
Just learning this myself. I will answer the second question:
Instead of using webpack-dev-server, you can just run an "express". use npm install "express" and create a server.js in the project's root dir, something like this:
var path = require("path");
var express = require("express");
var DIST_DIR = path.join(__dirname, "build");
var PORT = 3000;
var app = express();
//Serving the files on the dist folder
app.use(express.static(DIST_DIR));
//Send index.html when the user access the web
app.get("*", function (req, res) {
res.sendFile(path.join(DIST_DIR, "index.html"));
});
app.listen(PORT);
Then, in the package.json, add a script:
"start": "node server.js"
Finally, run the app: npm run start
to start the server
A detailed example can be seen at: https://alejandronapoles.com/2016/03/12/the-simplest-webpack-and-express-setup/ (the example code is not compatible with the latest packages, but it will work with small tweaks)
Here is a solution (based on Marcin Wyszynski's suggestion) which works where you want to pass a value into your controller but you aren't explicitly declaring the controller in your html (which ng-init seems to require) - if, for example, you are rendering your templates with ng-view and declaring each controller for the corresponding route via routeProvider.
JS
messageboard.directive('currentuser', ['CurrentUser', function(CurrentUser) {
return function(scope, element, attrs) {
CurrentUser.name = attrs.name;
};
}]);
html
<div ng-app="app">
<div class="view-container">
<div ng-view currentuser name="testusername" class="view-frame animate-view"></div>
</div>
</div>
In this solution, CurrentUser is a service which can be injected into any controller, with the .name property then available.
Two notes:
a problem I've encountered is that .name gets set after the controller loads, so as a workaround I have a short timeout before rendering username on the controller's scope. Is there a neat way of waiting until .name has been set on the service?
this feels like a very easy way to get a current user into your Angular App with all the authentication kept outside Angular. You could have a before_filter to prevent non-logged in users getting to the html where your Angular app is bootstrapped in, and within that html you could just interpolate the logged in user's name and even their ID if you wanted to interact with the user's details via http requests from your Angular app. You could allow non-logged in users to use the Angular App with a default 'guest user'. Any advice on why this approach would be bad would be welcome - it feels too easy to be sensible!)
Under Winpython : the Winpython-64bit-.../python_.../DLLs

Go with the following if you really want to use a loop. Nobody has actually answered how to feed data in a loop:
def plot(data):
fig = plt.figure(figsize=(100, 100))
for idx, k in enumerate(data.keys(), 1):
x, y = data[k].keys(), data[k].values
plt.subplot(63, 10, idx)
plt.bar(x, y)
plt.show()
Also you can use Lodash to direct convert object to array:
_.toArray({0:{a:4},1:{a:6},2:{a:5}})
[{a:4},{a:6},{a:5}]
In your case:
_.toArray(subjects).map((subject, i) => (
<li className="travelcompany-input" key={i}>
<span className="input-label">Name: {subject[name]}</span>
</li>
))}
shape
is a tuple that gives you an indication of the number of dimensions in the array. So in your case, since the index value of Y.shape[0]
is 0, your are working along the first dimension of your array.
From http://www.scipy.org/Tentative_NumPy_Tutorial#head-62ef2d3c0a5b4b7d6fdc48e4a60fe48b1ffe5006
An array has a shape given by the number of elements along each axis:
>>> a = floor(10*random.random((3,4)))
>>> a
array([[ 7., 5., 9., 3.],
[ 7., 2., 7., 8.],
[ 6., 8., 3., 2.]])
>>> a.shape
(3, 4)
and http://www.scipy.org/Numpy_Example_List#shape has some more examples.
To illustrate the mechanics of Antoine's answer:
protocol SomeProtocol {
func aMethod()
}
extension SomeProtocol {
func aMethod() {
print("extensionImplementation")
}
}
class protocolImplementingObject: SomeProtocol {
}
class protocolImplementingMethodOverridingObject: SomeProtocol {
func aMethod() {
print("classImplementation")
}
}
let noOverride = protocolImplementingObject()
let override = protocolImplementingMethodOverridingObject()
noOverride.aMethod() //prints "extensionImplementation"
override.aMethod() //prints "classImplementation"
I use it like this:
public class DateUtils {
static DateUtils instance;
private final DateFormat dateFormat;
private final DateFormat timeFormat;
private DateUtils() {
dateFormat = android.text.format.DateFormat.getDateFormat(MainApplication.context);
timeFormat = android.text.format.DateFormat.getTimeFormat(MainApplication.context);
}
public static DateUtils getInstance() {
if (instance == null) {
instance = new DateUtils();
}
return instance;
}
public synchronized static String formatDateTime(long timestamp) {
long milliseconds = timestamp * 1000;
Date dateTime = new Date(milliseconds);
String date = getInstance().dateFormat.format(dateTime);
String time = getInstance().timeFormat.format(dateTime);
return date + " " + time;
}
}
Here's a function I use a lot. The result is yyyy-mm-dd hh:mm:ss.nnn.
function date_and_time() {
var date = new Date();
//zero-pad a single zero if needed
var zp = function (val){
return (val <= 9 ? '0' + val : '' + val);
}
//zero-pad up to two zeroes if needed
var zp2 = function(val){
return val <= 99? (val <=9? '00' + val : '0' + val) : ('' + val ) ;
}
var d = date.getDate();
var m = date.getMonth() + 1;
var y = date.getFullYear();
var h = date.getHours();
var min = date.getMinutes();
var s = date.getSeconds();
var ms = date.getMilliseconds();
return '' + y + '-' + zp(m) + '-' + zp(d) + ' ' + zp(h) + ':' + zp(min) + ':' + zp(s) + '.' + zp2(ms);
}
varchar, Don't store separating characters you may want to format the phone numbers differently for different uses. so store (619) 123-4567 as 6191234567 I work with phone directory data and have found this to be the best practice.
I had this issue for 2 days, let me show you how I fixed it.
This was how the code looked when I was getting the error:
request.onload = function() {
// This is where we begin accessing the Json
let data = JSON.parse(this.response);
console.log(data)
}
This is what I changed to get the result I wanted:
request.onload = function() {
// This is where we begin accessing the Json
let data = JSON.parse(this.responseText);
console.log(data)
}
So all I really did was change
this.response
to this.responseText
.
It depends why the something is on the same line in the first place.

in the case of floats, display: block
in the case of inline content naturally flowing, nothing will defeat position: absolute
as the previous element will be taken out of the normal flow by it.

Can I check - do you mean a rectangular array ([,]
)or a jagged array ([][]
)?
It is quite easy to sort a jagged array; I have a discussion on that here. Obviously in this case the Comparison<T>
would involve a column instead of sorting by ordinal - but very similar.
Sorting a rectangular array is trickier... I'd probably be tempted to copy the data out into either a rectangular array or a List<T[]>
, and sort there, then copy back.
Here's an example using a jagged array:
static void Main()
{ // could just as easily be string...
int[][] data = new int[][] {
new int[] {1,2,3},
new int[] {2,3,4},
new int[] {2,4,1}
};
Sort<int>(data, 2);
}
private static void Sort<T>(T[][] data, int col)
{
Comparer<T> comparer = Comparer<T>.Default;
Array.Sort<T[]>(data, (x,y) => comparer.Compare(x[col],y[col]));
}
For working with a rectangular array... well, here is some code to swap between the two on the fly...
static T[][] ToJagged<T>(this T[,] array) {
int height = array.GetLength(0), width = array.GetLength(1);
T[][] jagged = new T[height][];
for (int i = 0; i < height; i++)
{
T[] row = new T[width];
for (int j = 0; j < width; j++)
{
row[j] = array[i, j];
}
jagged[i] = row;
}
return jagged;
}
static T[,] ToRectangular<T>(this T[][] array)
{
int height = array.Length, width = array[0].Length;
T[,] rect = new T[height, width];
for (int i = 0; i < height; i++)
{
T[] row = array[i];
for (int j = 0; j < width; j++)
{
rect[i, j] = row[j];
}
}
return rect;
}
// fill an existing rectangular array from a jagged array
static void WriteRows<T>(this T[,] array, params T[][] rows)
{
for (int i = 0; i < rows.Length; i++)
{
T[] row = rows[i];
for (int j = 0; j < row.Length; j++)
{
array[i, j] = row[j];
}
}
}
You can use the CSS property page-break-before
(or page-break-after
). Just set page-break-before: always
on those block-level elements (e.g., heading, div
, p
, or table
elements) that should start on a new line.
For example, to cause a line break before any 2nd level heading and before any element in class newpage
(e.g., <div class=newpage>
...), you would use
h2, .newpage { page-break-before: always }
function mailValidation(val) {
var expr = /^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/;
if (!expr.test(val)) {
$('#errEmail').text('Please enter valid email.');
}
else {
$('#errEmail').hide();
}
}
i also encounter that error once in a while, but when it does, it means that my branch is not up-to-date so i have to do git pull origin <current_branch>
Keep derived data but use the DSTROOT to specify the destination.
Use DEPLOYMENT_LOCATION to force deployment.
Use the undocumented DWARF_DSYM_FOLDER_PATH to copy the dSYM over too.
This allows you to use derived data location from xcodebuild and not have to do wacky stuff to find the app.
xcodebuild -sdk "iphoneos" -workspace Foo.xcworkspace -scheme Foo -configuration "Debug" DEPLOYMENT_LOCATION=YES DSTROOT=tmp DWARF_DSYM_FOLDER_PATH=tmp build
I agree with pgaur and rickerbh, recursive-fibonacci's complexity is O(2^n).
I came to the same conclusion by a rather simplistic but I believe still valid reasoning.
First, it's all about figuring out how many times recursive fibonacci function ( F() from now on ) gets called when calculating the Nth fibonacci number. If it gets called once per number in the sequence 0 to n, then we have O(n), if it gets called n times for each number, then we get O(n*n), or O(n^2), and so on.
So, when F() is called for a number n, the number of times F() is called for a given number between 0 and n-1 grows as we approach 0.
As a first impression, it seems to me that if we put it in a visual way, drawing a unit per time F() is called for a given number, wet get a sort of pyramid shape (that is, if we center units horizontally). Something like this:
n *
n-1 **
n-2 ****
...
2 ***********
1 ******************
0 ***************************
Now, the question is, how fast is the base of this pyramid enlarging as n grows?
Let's take a real case, for instance F(6)
F(6) * <-- only once
F(5) * <-- only once too
F(4) **
F(3) ****
F(2) ********
F(1) **************** <-- 16
F(0) ******************************** <-- 32
We see F(0) gets called 32 times, which is 2^5, which for this sample case is 2^(n-1).
Now, we want to know how many times F(x) gets called at all, and we can see the number of times F(0) is called is only a part of that.
If we mentally move all the *'s from F(6) to F(2) lines into F(1) line, we see that F(1) and F(0) lines are now equal in length. Which means, total times F() gets called when n=6 is 2x32=64=2^6.
Now, in terms of complexity:
O( F(6) ) = O(2^6)
O( F(n) ) = O(2^n)
You can create a variable with an application scope
via typings

.In an ideal world you'd achieve this simply using the following css
<style type="text/css">
span {
display: inline-block;
width: 50px;
}
</style>
This works on all browsers apart from FF2 and below.
Firefox 2 and lower don't support this value. You can use -moz-inline-box, but be aware that it's not the same as inline-block, and it may not work as you expect in some situations.

Using fs package we can create excel/CSV file from JSON data.
Step 1: Store JSON data in a variable (here it is in jsn variable).
Step 2: Create empty string variable(here it is data).
Step 3: Append every property of jsn to string variable data, while appending put '\t'
in-between 2 cells and '\n' after completing the row.
Code:
var fs = require('fs');
var jsn = [{
"name": "Nilesh",
"school": "RDTC",
"marks": "77"
},{
"name": "Sagar",
"school": "RC",
"marks": "99.99"
},{
"name": "Prashant",
"school": "Solapur",
"marks": "100"
}];
var data='';
for (var i = 0; i < jsn.length; i++) {
data=data+jsn[i].name+'\t'+jsn[i].school+'\t'+jsn[i].marks+'\n';
}
fs.appendFile('Filename.xls', data, (err) => {
if (err) throw err;
console.log('File created');
});
Inside controller inject Request object. So if you want to access request body inside controller method 'foo' do the following:
public function foo(Request $request){
$bodyContent = $request->getContent();
}
You can do it also in more 'object way' and still easy-to-read:
$('#content ul').append(
$('<li>').append(
$('<a>').attr('href','/user/messages').append(
$('<span>').attr('class', 'tab').append("Message center")
)));
You don't have to fight with quotes then, but must keep trace of braces :)

Provided you use the Angular-CLI to generate new projects, there's another way to make bootstrap accessible in Angular 2/4.
$ npm install --save bootstrap
. The --save
option will make bootstrap appear in the dependencies."styles"
array. The reference has to be the relative path to the bootstrap file downloaded with npm. In my case it's: "../node_modules/bootstrap/dist/css/bootstrap.min.css",
My example .angular-cli.json:
{
"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
"project": {
"name": "bootstrap-test"
},
"apps": [
{
"root": "src",
"outDir": "dist",
"assets": [
"assets",
"favicon.ico"
],
"index": "index.html",
"main": "main.ts",
"polyfills": "polyfills.ts",
"test": "test.ts",
"tsconfig": "tsconfig.app.json",
"testTsconfig": "tsconfig.spec.json",
"prefix": "app",
"styles": [
"../node_modules/bootstrap/dist/css/bootstrap.min.css",
"styles.css"
],
"scripts": [],
"environmentSource": "environments/environment.ts",
"environments": {
"dev": "environments/environment.ts",
"prod": "environments/environment.prod.ts"
}
}
],
"e2e": {
"protractor": {
"config": "./protractor.conf.js"
}
},
"lint": [
{
"project": "src/tsconfig.app.json"
},
{
"project": "src/tsconfig.spec.json"
},
{
"project": "e2e/tsconfig.e2e.json"
}
],
"test": {
"karma": {
"config": "./karma.conf.js"
}
},
"defaults": {
"styleExt": "css",
"component": {}
}
}
Now bootstrap should be part of your default settings.
Simply go to
yourusername/.bashrc (or yourusername/.bash_profile on MAC) by an editor
and add this code next to the last line:
alias yourcommand="cd /the_path_you_wish"
Then quit editor.
Then type:
source ~/.bashrc or source ~/.bash_profile on MAC.
now you can use: yourcommand in terminal
For versions 2.23 and above only,
Instead of these suggestions, you could use
git restore --staged <file>
in order to unstage
the file(s).
Apache Commons collection classes is the solution.

I had success doing it this way:
db.collection.update( { _id:...} , { $set: { 'key.another_key' : new_info } } );
I have a function that handles my profile updates dynamically
function update(prop, newVal) {
const str = `profile.${prop}`;
db.collection.update( { _id:...}, { $set: { [str]: newVal } } );
}
Note: 'profile' is specific to my implementation, it is just the string of the key that you would like to modify.
To dynamically construct the returnUrl in any View, try this:
@{
var formCollection =
new FormCollection
{
new FormCollection(Request.Form),
new FormCollection(Request.QueryString)
};
var parameters = new RouteValueDictionary();
formCollection.AllKeys
.Select(k => new KeyValuePair<string, string>(k, formCollection[k])).ToList()
.ForEach(p => parameters.Add(p.Key, p.Value));
}
<!-- Option #1 -->
@Html.ActionLink("Option #1", "Action", "Controller", parameters, null)
<!-- Option #2 -->
<a href="/Controller/Action/@[email protected](ViewContext.RouteData.Values["action"].ToString(), ViewContext.RouteData.Values["controller"].ToString(), parameters)">Option #2</a>
<!-- Option #3 -->
<a href="@Url.Action("Action", "Controller", new { object.ID, returnUrl = Url.Action(ViewContext.RouteData.Values["action"].ToString(), ViewContext.RouteData.Values["controller"].ToString(), parameters) }, null)">Option #3</a>
This also works in Layout Pages, Partial Views and Html Helpers

I have encounter issue with .net core 3.1. I have tried all the solution but did't work for me. Then I looked into IIS Log . The issue was Application unable to make connection with database because coonection string was invalid. So Please Look into IIS log to find the issue It may be any exception comes at runtime
This worked for me:
export _JAVA_OPTIONS="-Xmx1g"
It's important that you have no spaces because for me it did not work. I would suggest just copying and pasting. Then I ran:
java -XshowSettings:vm
and it will tell you:
Picked up _JAVA_OPTIONS: -Xmx1g
I would recommend start using Lyx, with that you can use Latex just as easy as OOO-Writer. It gives you the possibility to step into Latex deeper by manually adding Latex-Code to your Document. PDF is just one klick away after installatioin. Lyx is cross-plattform.
I believe it's better to use
$('#form-id').find('input').val('');
instead of
$('#form-id').children('input').val('');
incase you have checkboxes in your form use this to rest it:
$('#form-id').find('input:checkbox').removeAttr('checked');
Looking at your code, you need to set the frame of the movie player controller's view, and also add the movie player controller's view to your view. Also, don't forget to add MediaPlayer.framework to your target.
Here's some sample code:
#import <MediaPlayer/MediaPlayer.h>
@interface ViewController () {
MPMoviePlayerController *moviePlayerController;
}
@property (weak, nonatomic) IBOutlet UIView *movieView; // this should point to a view where the movie will play
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
// Instantiate a movie player controller and add it to your view
NSString *moviePath = [[NSBundle mainBundle] pathForResource:@"foo" ofType:@"mov"];
NSURL *movieURL = [NSURL fileURLWithPath:moviePath];
moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
[moviePlayerController.view setFrame:self.movieView.bounds]; // player's frame must match parent's
[self.movieView addSubview:moviePlayerController.view];
// Configure the movie player controller
moviePlayerController.controlStyle = MPMovieControlStyleNone;
[moviePlayerController prepareToPlay];
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
// Start the movie
[moviePlayerController play];
}
@end
The answer given by H Dog is great, but this approach was actually giving me some modal flicker in Internet Explorer 11. Bootstrap will first hide the modal removing the 'modal-open' class, and then (using H Dogs solution) we add the 'modal-open' class again. I suspect this is somehow causing the flicker I was seeing, maybe due to some slow HTML/CSS rendering.
Another solution is to prevent bootstrap in removing the 'modal-open' class from the body element in the first place. Using Bootstrap 3.3.7, this override of the internal hideModal function works perfectly for me.
$.fn.modal.Constructor.prototype.hideModal = function () {
var that = this
this.$element.hide()
this.backdrop(function () {
if ($(".modal:visible").length === 0) {
that.$body.removeClass('modal-open')
}
that.resetAdjustments()
that.resetScrollbar()
that.$element.trigger('hidden.bs.modal')
})
}
In this override, the 'modal-open' class is only removed when there are no visible modals on the screen. And you prevent one frame of removing and adding a class to the body element.
Just include the override after bootstrap have been loaded.
i believe the reason it is not working in your example is that you have imported datetime
like so :
from datetime import datetime
this leads to the error you see
In [30]: isinstance(x, datetime.date)
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
/<ipython-input-30-9a298ea6fce5> in <module>()
----> 1 isinstance(x, datetime.date)
TypeError: isinstance() arg 2 must be a class, type, or tuple of classes and types
if you simply import like so :
import datetime
the code will run as shown in all of the other answers
In [31]: import datetime
In [32]: isinstance(x, datetime.date)
Out[32]: True
In [33]:
Try this:
foreach (Item item in myItemsList)

This is a quite an old post which is still useful. All the solutions that proposes these two had little condition that not suite all:
SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);
This assumes or requires it to be a spring - web based projectAutowiringSpringBeanJobFactory
based approach mentioned in previous answer is very helpful, but the answer is specific to those who don't use pure vanilla quartz api but rather Spring's wrapper for the quartz to do the same.If you want to remain with pure Quartz implementation for scheduling(Quartz with Autowiring capabilities with Spring), I was able to do it as follows:
I was looking to do it quartz way as much as possible and thus little hack proves helpful.
public final class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory{
private AutowireCapableBeanFactory beanFactory;
public AutowiringSpringBeanJobFactory(final ApplicationContext applicationContext){
beanFactory = applicationContext.getAutowireCapableBeanFactory();
}
@Override
protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
final Object job = super.createJobInstance(bundle);
beanFactory.autowireBean(job);
beanFactory.initializeBean(job, job.getClass().getName());
return job;
}
}
@Configuration
public class SchedulerConfig {
@Autowired private ApplicationContext applicationContext;
@Bean
public AutowiringSpringBeanJobFactory getAutowiringSpringBeanJobFactory(){
return new AutowiringSpringBeanJobFactory(applicationContext);
}
}
private void initializeAndStartScheduler(final Properties quartzProperties)
throws SchedulerException {
//schedulerFactory.initialize(quartzProperties);
Scheduler quartzScheduler = schedulerFactory.getScheduler();
//Below one is the key here. Use the spring autowire capable job factory and inject here
quartzScheduler.setJobFactory(autowiringSpringBeanJobFactory);
quartzScheduler.start();
}
quartzScheduler.setJobFactory(autowiringSpringBeanJobFactory);
gives us an autowired job instance. Since AutowiringSpringBeanJobFactory
implicitly implements a JobFactory
, we now enabled an auto-wireable solution. Hope this helps!
SELECT d1.Short_Code

I know this question has an accepted answer, but I feel that it doesn't work in all cases.
For completeness and since I spent too much time on this, here is what we did: we ended up using a function from php.js (which is a pretty nice library for those more familiar with PHP but also doing a little JavaScript every now and then):
http://phpjs.org/functions/strip_tags:535
It seemed to be the only piece of JavaScript code which successfully dealt with all the different kinds of input I stuffed into my application. That is, without breaking it – see my comments about the <script />
tag above.
Make sure to put (move) the atom into Application directory.
I use zsh-autoenv which is based off autoenv.
zsh-autoenv automatically sources (known/whitelisted)
.autoenv.zsh
files, typically used in project root directories. It handles "enter" and leave" events, nesting, and stashing of variables (overwriting and restoring).
Here is an example:
; cd dtree
Switching to virtual environment: Development tree utiles
;dtree(feature/task24|?); cat .autoenv.zsh
# Autoenv.
echo -n "Switching to virtual environment: "
printf "\e[38;5;93m%s\e[0m\n" "Development tree utiles"
workon dtree
# eof
dtree(feature/task24|?); cat .autoenv_leave.zsh
deactivate
So when I leave the dtree
directory, the virtual environment is automatically exited.
"Development tree utiles"
is just a name… No hidden mean linking to the Illuminati in here.
We can use TRUNC function in Oracle DB. Here is an example.
SELECT TRUNC(TO_DATE('01 Jan 2018 08:00:00','DD-MON-YYYY HH24:MI:SS')) FROM DUAL
Output: 1/1/2018
The easiest way would be to use Python's built-in threading library. They're not "real" / kernel threads They have issues (like serialization), but are good enough. You'd want a queue & thread pool. One option is here, but it's trivial to write your own. You can't parallelize all 100,000 calls, but you can fire off 100 (or so) of them at the same time.
Simple way is to convert into column
SELECT COLUMN_VALUE FROM TABLE (SPLIT ('19869,19572,19223,18898,10155,'))
CREATE TYPE split_tbl as TABLE OF VARCHAR2(32767);
CREATE OR REPLACE FUNCTION split (p_list VARCHAR2, p_del VARCHAR2 := ',')
RETURN split_tbl
PIPELINED IS
l_idx PLS_INTEGER;
l_list VARCHAR2 (32767) := p_list;
l_value VARCHAR2 (32767);
BEGIN
LOOP
l_idx := INSTR (l_list, p_del);
IF l_idx > 0 THEN
PIPE ROW (SUBSTR (l_list, 1, l_idx - 1));
l_list := SUBSTR (l_list, l_idx + LENGTH (p_del));
ELSE
PIPE ROW (l_list);
EXIT;
END IF;
END LOOP;
RETURN;
END split;
If you want to iterate over a list and create a new list with "transformed" objects, you should use the map()
function of stream + collect()
. In the following example I find all people with the last name "l1" and each person I'm "mapping" to a new Employee instance.
public class Test {
public static void main(String[] args) {
List<Person> persons = Arrays.asList(
new Person("e1", "l1"),
new Person("e2", "l1"),
new Person("e3", "l2"),
new Person("e4", "l2")
);
List<Employee> employees = persons.stream()
.filter(p -> p.getLastName().equals("l1"))
.map(p -> new Employee(p.getName(), p.getLastName(), 1000))
.collect(Collectors.toList());
System.out.println(employees);
}
}
class Person {
private String name;
private String lastName;
public Person(String name, String lastName) {
this.name = name;
this.lastName = lastName;
}
// Getter & Setter
}
class Employee extends Person {
private double salary;
public Employee(String name, String lastName, double salary) {
super(name, lastName);
this.salary = salary;
}
// Getter & Setter
}

Once I faced with the issue when I did not know which the element currently stored in my variable (svg or html) but I needed to get it width and height. I created this function and want to share it:
function computeDimensions(selection) {
var dimensions = null;
var node = selection.node();
if (node instanceof SVGGraphicsElement) { // check if node is svg element
dimensions = node.getBBox();
} else { // else is html element
dimensions = node.getBoundingClientRect();
}
console.log(dimensions);
return dimensions;
}
Little demo in the hidden snippet below. We handle click on the blue div and on the red svg circle with the same function.
var svg = d3.select('svg')
.attr('width', 50)
.attr('height', 50);
function computeDimensions(selection) {
var dimensions = null;
var node = selection.node();
if (node instanceof SVGElement) {
dimensions = node.getBBox();
} else {
dimensions = node.getBoundingClientRect();
}
console.clear();
console.log(dimensions);
return dimensions;
}
var circle = svg
.append("circle")
.attr("r", 20)
.attr("cx", 30)
.attr("cy", 30)
.attr("fill", "red")
.on("click", function() { computeDimensions(circle); });
var div = d3.selectAll("div").on("click", function() { computeDimensions(div) });

Bitmasks are used when you want to encode multiple layers of information in a single number.
So (assuming unix file permissions) if you want to store 3 levels of access restriction (read, write, execute) you could check for each level by checking the corresponding bit.
rwx
---
110
110 in base 2 translates to 6 in base 10.
So you can easily check if someone is allowed to e.g. read the file by and'ing the permission field with the wanted permission.
Pseudocode:
PERM_READ = 4
PERM_WRITE = 2
PERM_EXEC = 1
user_permissions = 6
if (user_permissions & PERM_READ == TRUE) then
// this will be reached, as 6 & 4 is true
fi
You need a working understanding of binary representation of numbers and logical operators to understand bit fields.
Inserting data into the middle of a text file is not a simple task. If possible, you should append it to the end of your file.
The easiest way to append data some text file is to use build-in fs.appendFile(filename, data[, options], callback)
function from fs
module:
var fs = require('fs')
fs.appendFile('log.txt', 'new data', function (err) {
if (err) {
// append failed
} else {
// done
}
})
But if you want to write data to log file several times, then it'll be best to use fs.createWriteStream(path[, options])
function instead:
var fs = require('fs')
var logger = fs.createWriteStream('log.txt', {
flags: 'a' // 'a' means appending (old data will be preserved)
})
logger.write('some data') // append string to your file
logger.write('more data') // again
logger.write('and more') // again
Node will keep appending new data to your file every time you'll call .write
, until your application will be closed, or until you'll manually close the stream calling .end
:
logger.end() // close string

If you want a strongly typed list of anonymous types, you'll need to make the list an anonymous type too. The easiest way to do this is to project a sequence such as an array into a list, e.g.
var nodes = (new[] { new { Checked = false, /* etc */ } }).ToList();
Then you'll be able to access it like:
nodes.Any(n => n.Checked);
Because of the way the compiler works, the following then should also work once you have created the list, because the anonymous types have the same structure so they are also the same type. I don't have a compiler to hand to verify this though.
nodes.Add(new { Checked = false, /* etc */ });
it's the css file in the new one doesn't work. Try to include the old 1.7.* css file on your header too, and try again.
Also, did you try to do a .datepicker( "show" ) right after it constructed?
You can install other builds but not Appstore build.
From Xcode 8.2,drag and drop the build to simulator for the installation.
This website contains a much cleaner solution, it leaves pip intact as-well and one can easily switch between 3.5 and 3.6 and then whenever 3.7 is released.

A short summary:
sudo apt-get install python python-pip python3 python3-pip
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2
Then
$ pip -V
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.5/dist-packages (python 3.5)
Then to select python 3.6 run
sudo update-alternatives --config python3
and select '2'. Then
$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)
To update pip select the desired version and
pip3 install --upgrade pip
$ pip3 -V
pip 9.0.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)
Tested on Ubuntu 16.04.
The short answer is that you can't do it using JavaScript alone. You'd need a server-side handler to connect with the SMTP server to actually send the mail. There are many simple mail scripts online, such as this one for PHP:
Using a script like that, you'd POST the contents of your web form to the script, using a function like this:
And then the script would take those values, plus a username and password for the mail server, and connect to the server to send the mail.
The answer to "Given a class, see if instance has method (Ruby)" is better. Apparently Ruby has this built-in, and I somehow missed it. My answer is left for reference, regardless.
Ruby classes respond to the methods instance_methods
and public_instance_methods
. In Ruby 1.8, the first lists all instance method names in an array of strings, and the second restricts it to public methods. The second behavior is what you'd most likely want, since respond_to?
restricts itself to public methods by default, as well.
Foo.public_instance_methods.include?('bar')
In Ruby 1.9, though, those methods return arrays of symbols.
Foo.public_instance_methods.include?(:bar)
If you're planning on doing this often, you might want to extend Module
to include a shortcut method. (It may seem odd to assign this to Module
instead of Class
, but since that's where the instance_methods
methods live, it's best to keep in line with that pattern.)
class Module
def instance_respond_to?(method_name)
public_instance_methods.include?(method_name)
end
end
If you want to support both Ruby 1.8 and Ruby 1.9, that would be a convenient place to add the logic to search for both strings and symbols, as well.
it is not possible to pragmatically get the permission... but ill suggest you to put that line of code in try{} catch{} which make your app unfortunately stop... and in catch body make a dialog box which will navigate the user to small tutorial to enable the draw over other apps permission... then on yes button click put this code...
Intent callSettingIntent= new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
startActivity(callSettingIntent);
this intent is to directly open the list of draw over other apps to manage permissions and then from here it is one click to the draw over other apps Permissions ... i know this is Not the answer you're looking for... but Im doing this in my apps...
while working with Angular(5) , i face the same issue , but in my case i solved as follows:
component.html
<button type="button" class="btn btn-primary" data-target="#myModal"
(click)="showresult()">fff</button>
<div class="modal" id="myModal" role="dialog" tabindex="-1" data-backdrop="false">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>Modal body text goes here.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-primary">Save changes</button>
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
component.ts
NOTE: need to import jquery in ts file as "declare var $ :any;"
showresult(){
debugger
$('#myModal').modal('show');
}
Changes i made :
removed "data-toggle="modal" from Button tag (thanks to @miCRoSCoPiC_eaRthLinG this answer helps me here) in my case its showing modal so i created (click)="showresult()"
inside component.ts need to declare Jquery($) and inside button click method showresult() call " $('#myModal').modal('show');"
Something like this
string find = "item_manuf_id = 'some value'";
DataRow[] foundRows = table.Select(find);
Wrap the description in a textarea
element.
Since you haven't made any commits yet, you can save all your changes to the stash, create and switch to a new branch, then pop those changes back into your working tree:
git stash # save local modifications to new stash
git checkout -b topic/newbranch
git stash pop # apply stash and remove it from the stash list
You can filter by multiple columns (more than two) by using the np.logical_and
operator to replace &
(or np.logical_or
to replace |
)
Here's an example function that does the job, if you provide target values for multiple fields. You can adapt it for different types of filtering and whatnot:
def filter_df(df, filter_values):
"""Filter df by matching targets for multiple columns.
Args:
df (pd.DataFrame): dataframe
filter_values (None or dict): Dictionary of the form:
`{<field>: <target_values_list>}`
used to filter columns data.
"""
import numpy as np
if filter_values is None or not filter_values:
return df
return df[
np.logical_and.reduce([
df[column].isin(target_values)
for column, target_values in filter_values.items()
])
]
Usage:
df = pd.DataFrame({'a': [1, 2, 3, 4], 'b': [1, 2, 3, 4]})
filter_df(df, {
'a': [1, 2, 3],
'b': [1, 2, 4]
})
You can use code like this:
char *MyFunction(some arguments...)
{
char *pointer = malloc(size for the new array);
if (!pointer)
An error occurred, abort or do something about the error.
return pointer; // Return address of memory to the caller.
}
When you do this, the memory should later be freed, by passing the address to free.
There are other options. A routine might return a pointer to an array (or portion of an array) that is part of some existing structure. The caller might pass an array, and the routine merely writes into the array, rather than allocating space for a new array.
If you have more than one view in the layout file android.R.layout.simple_list_item_1
then you'll have to pass the third argument android.R.id.text1
to specify the view that should be filled with the array elements (values). But if you have just one view in your layout file, there is no need to specify the third argument.
I was facing the same issue of having the dialog not opening centered and scrolling my page to the top. The tag that I'm using to open the dialog is an anchor tag:
<a href="#">View More</a>
The pound symbol was causing the issue for me. All I did was modify the href in the anchor like so:
<a href="javascript:{}">View More</a>
Now my page is happy and centering the dialogs.
Just try to run openssl.exe as administrator.
Make sure that your package is installed in your $GOPATH
directory or already inside your workspace/package.
For example: if your $GOPATH = "c:\go"

You'll want to use the process.argv
array to access the command-line arguments to get the filename and the FileSystem module (fs) to read the file. For example:
// Make sure we got a filename on the command line.
if (process.argv.length < 3) {
console.log('Usage: node ' + process.argv[1] + ' FILENAME');
process.exit(1);
}
// Read the file and print its contents.
var fs = require('fs')
, filename = process.argv[2];
fs.readFile(filename, 'utf8', function(err, data) {
if (err) throw err;
console.log('OK: ' + filename);
console.log(data)
});
To break that down a little for you process.argv
will usually have length two, the zeroth item being the "node" interpreter and the first being the script that node is currently running, items after that were passed on the command line. Once you've pulled a filename from argv then you can use the filesystem functions to read the file and do whatever you want with its contents. Sample usage would look like this:
$ node ./cat.js file.txt
OK: file.txt
This is file.txt!
[Edit] As @wtfcoder mentions, using the "fs.readFile()
" method might not be the best idea because it will buffer the entire contents of the file before yielding it to the callback function. This buffering could potentially use lots of memory but, more importantly, it does not take advantage of one of the core features of node.js - asynchronous, evented I/O.
The "node" way to process a large file (or any file, really) would be to use fs.read()
and process each available chunk as it is available from the operating system. However, reading the file as such requires you to do your own (possibly) incremental parsing/processing of the file and some amount of buffering might be inevitable.

According https://apiblueprint.org/documentation/examples/13-named-endpoints.html is a resource a "general" place of storage of the given entity - e.g. /customers/30654/orders, whereas an endpoint is the concrete action (HTTP Method) over the given resource. So one resource can have multiple endpoints.
try this its work fine

List.Exists (Object method - MSDN)
Determines whether the List(T) contains elements that match the conditions defined by the specified predicate.
This exists since .NET 2.0, so before LINQ. Meant to be used with the Predicate delegate, but lambda expressions are backward compatible. Also, just List has this (not even IList)
IEnumerable.Any (Extension method - MSDN)
Determines whether any element of a sequence satisfies a condition.
This is new in .NET 3.5 and uses Func(TSource, bool) as argument, so this was intended to be used with lambda expressions and LINQ.
In behaviour, these are identical.
You can use PreferredSize:
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Example',
home: Scaffold(
appBar: PreferredSize(
preferredSize: Size.fromHeight(50.0), // here the desired height
child: AppBar(
// ...
)
),
body: // ...
)
);
}
}
Yes there is, you can simply put <hr>
in your code where you want it, I already use it in one of my admin panel side bar.
IMHO Lookup tables is the way to go, with referential integrity. But only if you avoid "Evil Magic Numbers" by following an example such as this one: Generate enum from a database lookup table using T4
Have Fun!
I got the same error. In my case, I was using a mapped drive to edit code off of a second computer, that computer was running linux. Not sure exactly why gulp-watch relies on operating system compatibility prior to install (I would assume it has to do with security purposes). Essentially the error is checking against your operating system and the operating system calling the node module, in my case the two operating systems were not the same so it threw it error. Which from the looks of your error is the same as mine.
The Error
Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
How I fixed it?
I logged into the linux computer directly and ran
npm install --save-dev <module-name>
Then went back into my coding environment and everything was fine after that.
Hope that helps!

For Bootstrap 3 the default radio/button-group structure is :
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input type="radio" name="options" id="option1"> Option 1
</label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option2"> Option 2
</label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option3"> Option 3
</label>
</div>
And you can select the active one like this:
$('.btn-primary').on('click', function(){
alert($(this).find('input').attr('id'));
});
You can simply use this:
if ($("#one")){
alert('yes');
}
if ($("#two")){
alert('yes');
}
if ($("#three")){
alert('yes');
}
if ($("#four")){
alert('no');
}
Sorry, my mistake, it does not work.
For me Upgrading Gradle works.Look for update at Android Website then add it in your build.gradle (Project) like this
dependencies {
classpath 'com.android.tools.build:gradle:2.2.0-alpha4'
....
}
then sync project with gradle file plus it might be happened sometimes because of java.exe (in my case) just force kill java.exe from task manager in windows then re run program
Basically, there are two ways to clear the cache:
<form autocomplete="off"></form>
or
$('#Textfiledid').attr('autocomplete', 'off');
For simple cases, we could redirect the Standard Out (STDOUT) and Standard Error (STDERR) streams directly to a file(say, test.log) using '>' and '2>&1'
Example:
// test.js
(function() {
// Below outputs are sent to Standard Out (STDOUT) stream
console.log("Hello Log");
console.info("Hello Info");
// Below outputs are sent to Standard Error (STDERR) stream
console.error("Hello Error");
console.warn("Hello Warning");
})();
node test.js > test.log 2>&1
As per the POSIX standard, 'input', 'output' and 'error' streams are identified by the positive integer file descriptors (0, 1, 2). i.e., stdin is 0, stdout is 1, and stderr is 2.
Step 1: '2>&1' will redirect from 2 (stderr) to 1 (stdout)
Step 2: '>' will redirect from 1 (stdout) to file (test.log)
textbox.Focus();
textbox.SelectionStart = 0;
textbox.SelectionLength = textbox.Text.Length;
I was facing a similar difficulty and none of the solutions presented here were optimal for what I was working on. What I had was a series of functions to display content in a modal and I was trying to refactor it under a single object definition making the functions, methods of the class. The problem came in when I found one of the methods created some nav-buttons inside the modal themselves which used an onClick to one of the functions -- now an object of the class. I have considered (and am still considering) other methods to handle these nav buttons, but I was able to find the variable name for the class itself by sweeping the variables defined in the parent window. What I did was search for anything matching the 'instanceof' my class, and in case there might be more than one, I compared a specific property that was likely to be unique to each instance:
var myClass = function(varName)
{
this.instanceName = ((varName != null) && (typeof(varName) == 'string') && (varName != '')) ? varName : null;
/**
* caching autosweep of window to try to find this instance's variable name
**/
this.getInstanceName = function() {
if(this.instanceName == null)
{
for(z in window) {
if((window[z] instanceof myClass) && (window[z].uniqueProperty === this.uniqueProperty)) {
this.instanceName = z;
break;
}
}
}
return this.instanceName;
}
}
char* str = "blablabla";
You should not modify this string at all. It resides in implementation defined read only region. Modifying it causes Undefined Behavior.
You need a char array not a string literal.
Good Read:
What is the difference between char a[] = "string"; and char *p = "string";
If you need the same rows but just a random sample then,
import random
new_array = random.sample(old_array,x)
Here x, has to be an 'int' defining the number of rows you want to randomly pick.
When the compiler sees add(3, 4)
it needs to know what that means. With the forward declaration you basically tell the compiler that add
is a function that takes two ints and returns an int. This is important information for the compiler becaus it needs to put 4 and 5 in the correct representation onto the stack and needs to know what type the thing returned by add is.
At that time, the compiler is not worried about the actual implementation of add
, ie where it is (or if there is even one) and if it compiles. That comes into view later, after compiling the source files when the linker is invoked.
A generic way:
[tuple(x) for x in data_set.to_records(index=False)]
Instead of using success
, I change it to then
and it works.
here is the code:
lgrg.controller('login', function($scope, $window, $http) {
$scope.loginUser = {};
$scope.submitForm = function() {
$scope.errorInfo = null
$http({
method : 'POST',
url : '/login',
headers : {'Content-Type': 'application/json'}
data: $scope.loginUser
}).then(function(data) {
if (!data.status) {
$scope.errorInfo = data.info
} else {
//page jump
$window.location.href = '/admin';
}
});
};
});
Here is a newer way of how to turn a Console Application to a Windows Service as a Worker Service based on the latest .Net Core 3.1.
If you create a Worker Service from Visual Studio 2019 it will give you almost everything you need for creating a Windows Service out of the box, which is also what you need to change to the console application in order to convert it to a Windows Service.
Here are the changes you need to do:
Install the following NuGet packages
Install-Package Microsoft.Extensions.Hosting.WindowsServices -Version 3.1.0
Install-Package Microsoft.Extensions.Configuration.Abstractions -Version 3.1.0
Change Program.cs to have an implementation like below:
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
namespace ConsoleApp
{
class Program
{
public static void Main(string[] args)
{
CreateHostBuilder(args).UseWindowsService().Build().Run();
}
private static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureServices((hostContext, services) =>
{
services.AddHostedService<Worker>();
});
}
}
and add Worker.cs where you will put the code which will be run by the service operations:
using Microsoft.Extensions.Hosting;
using System.Threading;
using System.Threading.Tasks;
namespace ConsoleApp
{
public class Worker : BackgroundService
{
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
//do some operation
}
public override Task StartAsync(CancellationToken cancellationToken)
{
return base.StartAsync(cancellationToken);
}
public override Task StopAsync(CancellationToken cancellationToken)
{
return base.StopAsync(cancellationToken);
}
}
}
When everything is ready, and the application has built successfully, you can use sc.exe to install your console application exe as a Windows Service with the following command:
sc.exe create DemoService binpath= "path/to/your/file.exe"
Keep in mind, in the general case you could have multiple NAT translations going on, and multiple dns servers, each operating on different NAT translation levels.
What if you have carrier grade NAT, and want to communicate with other customers of the same carrier? In the general case you never know for sure because you might appear with different host names at every NAT translation.
For unsigned numbers you can use these classes from Guava library:
They support various operations:
The thing that seems missing at the moment are byte shift operators. If you need those you can use BigInteger from Java.
This is kind of an old question but I wanted to mentioned here the pathlib library in Python3.
If you write:
from pathlib import Path
path: str = 'C:\\Users\\myUserName\\project\\subfolder'
osDir = Path(path)
or
path: str = "C:\\Users\\myUserName\\project\\subfolder"
osDir = Path(path)
osDir will be the same result.
Also if you write it as:
path: str = "subfolder"
osDir = Path(path)
absolutePath: str = str(Path.absolute(osDir))
you will get back the absolute directory as
'C:\\Users\\myUserName\\project\\subfolder'
You can check more for the pathlib library here.
I use this... but it requires the user to click on the select box...
Here are the 2 javascript functions
function expand(obj)
{
obj.size = 5;
}
function unexpand(obj)
{
obj.size = 1;
}
then i create the select box
<select id="test" multiple="multiple" name="foo" onFocus="expand(this)" onBlur="unexpand(this)">
<option >option1</option>
<option >option2</option>
<option >option3</option>
<option >option4</option>
<option >option5</option>
</select>
I know this code is a little late, but i hope it helps someone who had the same problem as me.
ps/fyi i have not tested the code above (i create my select box dynamically), and the code i did write was only tested in FireFox.
If you are using Go 1.5 above, you can try to use vendoring feature. It allows you to put your local package under vendor folder and import it with shorter path. In your case, you can put your common and routers folder inside vendor folder so it would be like
myapp/
--vendor/
----common/
----routers/
------middleware/
--main.go
and import it like this
import (
"common"
"routers"
"routers/middleware"
)
This will work because Go will try to lookup your package starting at your project’s vendor directory (if it has at least one .go file) instead of $GOPATH/src.
FYI: You can do more with vendor, because this feature allows you to put "all your dependency’s code" for a package inside your own project's directory so it will be able to always get the same dependencies versions for all builds. It's like npm or pip in python, but you need to manually copy your dependencies to you project, or if you want to make it easy, try to look govendor by Daniel Theophanes
For more learning about this feature, try to look up here
Understanding and Using Vendor Folder by Daniel Theophanes

I hope you or someone else find it helpfully
I solved my issue by doing this:
Strangely it started working again after that.
You have to get back out of the Iframe with the following code:
driver.switchTo().frame(driver.findElement(By.id("frameId")));
//do your stuff
driver.switchTo().defaultContent();
hope that helps
I was getting the same issue and found that OpenSSH service was not running and it was causing the issue. After starting the SSH service it worked.
To check if SSH service is running or not:
ssh localhost
To start the service, if OpenSSH is already installed:
sudo /etc/init.d/ssh start
"Egg" is a single-file importable distribution format for Python-related projects.
"The Quick Guide to Python Eggs" notes that "Eggs are to Pythons as Jars are to Java..."
Eggs actually are richer than jars; they hold interesting metadata such as licensing details, release dependencies, etc.
Just to note that nginx has now support for Websockets on the release 1.3.13. Example of use:
location /websocket/ {
proxy_pass ?http://backend_host;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 86400;
}
You can also check the nginx changelog and the WebSocket proxying documentation.
The path should be left blank to make it default component.
{ path: '', component: DashboardComponent },
I am very late to this but I want to mention that that new is actually unsafe in the Obj-C with Swift world. Swift will only create a default init method if you do not create any other initializer. Calling new on a swift class with a custom initializer will cause a crash. If you use alloc/init then the compiler will properly complain that init does not exist.
I find it very useful to append both stdout and stderr to a log file. I was glad to see a solution by alfonx with exec > >(tee -a)
, because I was wondering how to accomplish this using exec
. I came across a creative solution using here-doc syntax and .
: https://unix.stackexchange.com/questions/80707/how-to-output-text-to-both-screen-and-file-inside-a-shell-script
I discovered that in zsh, the here-doc solution can be modified using the "multios" construct to copy output to both stdout/stderr and the log file:
#!/bin/zsh
LOG=$0.log
# 8 is an arbitrary number;
# multiple redirects for the same file descriptor
# triggers "multios"
. 8<<\EOF /dev/fd/8 2>&2 >&1 2>>$LOG >>$LOG
# some commands
date >&2
set -x
echo hi
echo bye
EOF
echo not logged
It is not as readable as the exec
solution but it has the advantage of allowing you to log just part of the script. Of course, if you omit the EOF then the whole script is executed with logging. I'm not sure how zsh
implements multios, but it may have less overhead than tee
. Unfortunately it seems that one cannot use multios with exec
.
My question is when should a use a double and when should I use a decimal type?
decimal
for when you work with values in the range of 10^(+/-28) and where you have expectations about the behaviour based on base 10 representations - basically money.
double
for when you need relative accuracy (i.e. losing precision in the trailing digits on large values is not a problem) across wildly different magnitudes - double
covers more than 10^(+/-300). Scientific calculations are the best example here.
which type is suitable for money computations?
decimal, decimal, decimal
Accept no substitutes.
The most important factor is that double
, being implemented as a binary fraction, cannot accurately represent many decimal
fractions (like 0.1) at all and its overall number of digits is smaller since it is 64-bit wide vs. 128-bit for decimal
. Finally, financial applications often have to follow specific rounding modes (sometimes mandated by law). decimal
supports these; double
does not.
When an attribute value contains a placeholder (see format below), the manifest merger will swap this placeholder value with an injected value. Injected values are specified in the build.gradle. The syntax for placeholder values is ${name} since @ is reserved for links. After the last file merging occurred, and before the resulting merged android manifest file is written out, all values with a placeholder will be swapped with injected values. A build breakage will be generated if a variable name is unknown.
from http://tools.android.com/tech-docs/new-build-system/user-guide/manifest-merger#TOC-Build-error
stack size can indeed be unlimited. _STK_LIM
is the default, _STK_LIM_MAX
is something that differs per architecture, as can be seen from include/asm-generic/resource.h
:
/*
* RLIMIT_STACK default maximum - some architectures override it:
*/
#ifndef _STK_LIM_MAX
# define _STK_LIM_MAX RLIM_INFINITY
#endif
As can be seen from this example generic value is infinite, where RLIM_INFINITY
is, again, in generic case defined as:
/*
* SuS says limits have to be unsigned.
* Which makes a ton more sense anyway.
*
* Some architectures override this (for compatibility reasons):
*/
#ifndef RLIM_INFINITY
# define RLIM_INFINITY (~0UL)
#endif
So I guess the real answer is - stack size CAN be limited by some architecture, then unlimited stack trace will mean whatever _STK_LIM_MAX
is defined to, and in case it's infinity - it is infinite. For details on what it means to set it to infinite and what implications it might have, refer to the other answer, it's way better than mine.
You can do it using only the shell, no need for tr
or sed

Healpix solves a closely related problem (pixelating the sphere with equal area pixels):
http://healpix.sourceforge.net/
It's probably overkill, but maybe after looking at it you'll realize some of it's other nice properties are interesting to you. It's way more than just a function that outputs a point cloud.
I landed here trying to find it again; the name "healpix" doesn't exactly evoke spheres...
There is a fairly well maintained repo on github that has a CSV (with semicolon delimiters), XML, and JSON source of countries, country codes, and other information.
The Mach-O object file format used by Mac OS X for executables and libraries distinguishes between shared libraries and dynamically loaded modules. Use otool -hv some_file
to see the filetype of some_file
.
Mach-O shared libraries have the file type MH_DYLIB
and carry the extension .dylib. They can be linked against with the usual static linker flags, e.g. -lfoo
for libfoo.dylib. They can be created by passing the -dynamiclib
flag to the compiler. (-fPIC
is the default and needn't be specified.)
Loadable modules are called "bundles" in Mach-O speak. They have the file type MH_BUNDLE
. They can carry any extension; the extension .bundle
is recommended by Apple, but most ported software uses .so
for the sake of compatibility. Typically, you'll use bundles for plug-ins that extend an application; in such situations, the bundle will link against the application binary to gain access to the application’s exported API. They can be created by passing the -bundle
flag to the compiler.
Both dylibs and bundles can be dynamically loaded using the dl
APIs (e.g. dlopen
, dlclose
). It is not possible to link against bundles as if they were shared libraries. However, it is possible that a bundle is linked against real shared libraries; those will be loaded automatically when the bundle is loaded.
Historically, the differences were more significant. In Mac OS X 10.0, there was no way to dynamically load libraries. A set of dyld APIs (e.g. NSCreateObjectFileImageFromFile
, NSLinkModule
) were introduced with 10.1 to load and unload bundles, but they didn't work for dylibs. A dlopen
compatibility library that worked with bundles was added in 10.3; in 10.4, dlopen
was rewritten to be a native part of dyld and added support for loading (but not unloading) dylibs. Finally, 10.5 added support for using dlclose
with dylibs and deprecated the dyld APIs.
On ELF systems like Linux, both use the same file format; any piece of shared code can be used as a library and for dynamic loading.
Finally, be aware that in Mac OS X, "bundle" can also refer to directories with a standardized structure that holds executable code and the resources used by that code. There is some conceptual overlap (particularly with "loadable bundles" like plugins, which generally contain executable code in the form of a Mach-O bundle), but they shouldn't be confused with Mach-O bundles discussed above.

If you could send an SMS within a program on the iPhone, you'll be able to write games that spam people in the background. I'm sure you really want to have spams from your friends, "Try out this new game! It roxxers my boxxers, and yours will be too! roxxersboxxers.com!!!! If you sign up now you'll get 3,200 RB points!!"
Apple has restrictions for automated (or even partially automated) SMS and dialing operations. (Imagine if the game instead dialed 911 at a particular time of day)
Your best bet is to set up an intermediate server on the internet that uses an online SMS sending service and send the SMS via that route if you need complete automation. (ie, your program on the iPhone sends a UDP packet to your server, which sends the real SMS)
iOS 4, however, now provides a viewController
you can import into your application. You prepopulate the SMS fields, then the user can initiate the SMS send within the controller. Unlike using the "SMS:..." url format, this allows your application to stay open, and allows you to populate both the to and the body fields. You can even specify multiple recipients.
This prevents applications from sending automated SMS without the user explicitly aware of it. You still cannot send fully automated SMS from the iPhone itself, it requires some user interaction. But this at least allows you to populate everything, and avoids closing the application.
The MFMessageComposeViewController class is well documented, and tutorials show how easy it is to implement.
iOS 5 includes messaging for iPod touch and iPad devices, so while I've not yet tested this myself, it may be that all iOS devices will be able to send SMS via MFMessageComposeViewController. If this is the case, then Apple is running an SMS server that sends messages on behalf of devices that don't have a cellular modem.
No changes to this class.
You can now check to see if the message medium you are using will accept a subject or attachments, and what kind of attachments it will accept. You can edit the subject and add attachments to the message, where the medium allows it.

Keep in mind that this won't work on phones without iOS 4, and it won't work on the iPod touch or the iPad, except, perhaps, under iOS 5. You must either detect the device and iOS limitations prior to using this controller, or risk restricting your app to recently upgraded 3G, 3GS, and 4 iPhones.
However, an intermediate server that sends SMS will allow any and all of these iOS devices to send SMS as long as they have internet access, so it may still be a better solution for many applications. Alternately, use both, and only fall back to an online SMS service when the device doesn't support it.

If you're using WPF there is a LoadCompleted
event.
If it's Windows.Forms
, the DocumentCompleted
event should be the correct one. If the page you're loading has frames, your WebBrowser
control will fire the DocumentCompleted
event for each frame (see here for more details). I would suggest checking the IsBusy
property each time the event is fired and if it is false then your page is fully done loading.
I've had the same problem with you.
cd to ../etc/ then use ls to make sure your "paths" file is in , vim paths, add "/usr/local/bin" at the end of the file.
It might be too late to answer this but I just had the problem and I kept installing and uninstalling, it turns out the the problem happens when you're installing pandas
to a version of python
and trying to run the program using another python version
So to start off, run:
which python
python --version
which pip
make sure both are aligned, most probably, python is 2.7
and pip is working on 3.x
or pip is coming from anaconda's python version which is highly likely to be 3.x
as well
Incase of python
redirects to 2.7, and pip redirects to pip3, install pandas using pip install pandas
and use python3 file_name.py
to run the program.
It's not a cut and paste. The CASE
expression must return a value, and you are returning a string containing SQL (which is technically a value but of a wrong type). This is what you wanted to write, I think:
SELECT * FROM [Purchasing].[Vendor] WHERE
CASE
WHEN @url IS null OR @url = '' OR @url = 'ALL'
THEN PurchasingWebServiceURL LIKE '%'
WHEN @url = 'blank'
THEN PurchasingWebServiceURL = ''
WHEN @url = 'fail'
THEN PurchasingWebServiceURL NOT LIKE '%treyresearch%'
ELSE PurchasingWebServiceURL = '%' + @url + '%'
END
I also suspect that this might not work in some dialects, but can't test now (Oracle, I'm looking at you), due to not having booleans.
However, since @url
is not dependent on the table values, why not make three different queries, and choose which to evaluate based on your parameter?
The code snippet below shows how to display n digits. The trick is to set variable pp to 1 followed by n zeros. In the example below, variable pp value has 5 zeros, so 5 digits will be displayed.
double pp = 10000;
double myVal = 22.268699999999967;
String needVal = "22.2687";
double i = (5.0/pp);
String format = "%10.4f";
String getVal = String.format(format,(Math.round((myVal +i)*pp)/pp)-i).trim();
According to the man page the -P flag is:
-P prefix --directory-prefix=prefix Set directory prefix to prefix. The directory prefix is the directory where all other files and subdirectories will be saved to, i.e. the top of the retrieval tree. The default is . (the current directory).
This mean that it only specifies the destination but where to save the directory tree. It does not flatten the tree into just one directory. As mentioned before the -nd flag actually does that.
@Jon in the future it would be beneficial to describe what the flag does so we understand how something works.

It is the 1).spinning and 2).polling loop of your examples that people caution against, not the Thread.Sleep() part. I think Thread.Sleep() is usually added to easily improve code that is spinning or in a polling loop, so it is just associated with "bad" code.
In addition people do stuff like:
while(inWait)Thread.Sleep(5000);
where the variable inWait is not accessed in a thread-safe manner, which also causes problems.
What programmers want to see is the threads controlled by Events and Signaling and Locking constructs, and when you do that you won't have need for Thread.Sleep(), and the concerns about thread-safe variable access are also eliminated. As an example, could you create an event handler associated with the FileSystemWatcher class and use an event to trigger your 2nd example instead of looping?
As Andreas N. mentioned, read Threading in C#, by Joe Albahari, it is really really good.
Margin is the spacing outside your element, just as padding is the spacing inside your element.
Setting the bottom margin indicates what distance you want below the current block. Setting a negative top margin indicates that you want negative spacing above your block. Negative spacing may in itself be a confusing concept, but just the way positive top margin pushes content down, a negative top margin pulls content up.
This post was the starting point of my solution, lots of good ideas here so I though I would share my results. The main insight is that I've found a way to get around the slowness of keypoint-based image matching by exploiting the speed of phash.
For the general solution, it's best to employ several strategies. Each algorithm is best suited for certain types of image transformations and you can take advantage of that.
At the top, the fastest algorithms; at the bottom the slowest (though more accurate). You might skip the slow ones if a good match is found at the faster level.
I am having very good results with phash. The accuracy is good for rescaled images. It is not good for (perceptually) modified images (cropped, rotated, mirrored, etc). To deal with the hashing speed we must employ a disk cache/database to maintain the hashes for the haystack.
The really nice thing about phash is that once you build your hash database (which for me is about 1000 images/sec), the searches can be very, very fast, in particular when you can hold the entire hash database in memory. This is fairly practical since a hash is only 8 bytes.
For example, if you have 1 million images it would require an array of 1 million 64-bit hash values (8 MB). On some CPUs this fits in the L2/L3 cache! In practical usage I have seen a corei7 compare at over 1 Giga-hamm/sec, it is only a question of memory bandwidth to the CPU. A 1 Billion-image database is practical on a 64-bit CPU (8GB RAM needed) and searches will not exceed 1 second!
For modified/cropped images it would seem a transform-invariant feature/keypoint detector like SIFT is the way to go. SIFT will produce good keypoints that will detect crop/rotate/mirror etc. However the descriptor compare is very slow compared to hamming distance used by phash. This is a major limitation. There are a lot of compares to do, since there are maximum IxJxK descriptor compares to lookup one image (I=num haystack images, J=target keypoints per haystack image, K=target keypoints per needle image).
To get around the speed issue, I tried using phash around each found keypoint, using the feature size/radius to determine the sub-rectangle. The trick to making this work well, is to grow/shrink the radius to generate different sub-rect levels (on the needle image). Typically the first level (unscaled) will match however often it takes a few more. I'm not 100% sure why this works, but I can imagine it enables features that are too small for phash to work (phash scales images down to 32x32).
Another issue is that SIFT will not distribute the keypoints optimally. If there is a section of the image with a lot of edges the keypoints will cluster there and you won't get any in another area. I am using the GridAdaptedFeatureDetector in OpenCV to improve the distribution. Not sure what grid size is best, I am using a small grid (1x3 or 3x1 depending on image orientation).
You probably want to scale all the haystack images (and needle) to a smaller size prior to feature detection (I use 210px along maximum dimension). This will reduce noise in the image (always a problem for computer vision algorithms), also will focus detector on more prominent features.
For images of people, you might try face detection and use it to determine the image size to scale to and the grid size (for example largest face scaled to be 100px). The feature detector accounts for multiple scale levels (using pyramids) but there is a limitation to how many levels it will use (this is tunable of course).
The keypoint detector is probably working best when it returns less than the number of features you wanted. For example, if you ask for 400 and get 300 back, that's good. If you get 400 back every time, probably some good features had to be left out.
The needle image can have less keypoints than the haystack images and still get good results. Adding more doesn't necessarily get you huge gains, for example with J=400 and K=40 my hit rate is about 92%. With J=400 and K=400 the hit rate only goes up to 96%.
We can take advantage of the extreme speed of the hamming function to solve scaling, rotation, mirroring etc. A multiple-pass technique can be used. On each iteration, transform the sub-rectangles, re-hash, and run the search function again.
In case you want to sort dates with descending order the minus sign doesn't work with Dates.
out <- DF[rev(order(as.Date(DF$end))),]
However you can have the same effect with a general purpose function: rev(). Therefore, you mix rev and order like:
#init data
DF <- data.frame(ID=c('ID3', 'ID2','ID1'), end=c('4/1/09 12:00', '6/1/10 14:20', '1/1/11 11:10')
#change order
out <- DF[rev(order(as.Date(DF$end))),]
Hope it helped.
Check for nil and unwrap using "!":
let color = colorChoiceSegmentedControl.titleForSegmentAtIndex(colorChoiceSegmentedControl.selectedSegmentIndex)
println(color) // Optional("Red")
if color != nil {
println(color!) // "Red"
let imageURLString = "http://hahaha.com/ha.php?color=\(color!)"
println(imageURLString)
//"http://hahaha.com/ha.php?color=Red"
}
Fully agree with Erickson that PBKDF2 is the answer.
If you don't have that option, or only need to use a hash, Apache Commons DigestUtils is much easier than getting JCE code right: https://commons.apache.org/proper/commons-codec/apidocs/org/apache/commons/codec/digest/DigestUtils.html
If you use a hash, go with sha256 or sha512. This page has good recommendations on password handling and hashing (note it doesn't recommend hashing for password handling): http://www.daemonology.net/blog/2009-06-11-cryptographic-right-answers.html
To use Google Maps/Places APIs now, you're required to use an API Key. So the API URL will change from

I came across the same problem and have found a simple solution. Add after calling the append function a document ready.
$("#root").append(child);_x000D_
$(document).ready(function () {_x000D_
// Action after append is completly done_x000D_
});
_x000D_
print then.date()
What you want is a datetime.date object. What you have is a datetime.datetime object. You can either change the object when you print as per above, or do the following when creating the object:
then = datetime.datetime.strptime(when, '%Y-%m-%d').date()
It means somewhere in your chain of calls, you tried to access a Property or call a method on an object that was null
.
Given your statement:
img1.ImageUrl = ConfigurationManager
.AppSettings
.Get("Url")
.Replace("###", randomString)
+ Server.UrlEncode(
((System.Web.UI.MobileControls.Form)Page
.FindControl("mobileForm"))
.Title);
I'm guessing either the call to AppSettings.Get("Url")
is returning null because the value isn't found or the call to Page.FindControl("mobileForm")
is returning null because the control isn't found.
You could easily break this out into multiple statements to solve the problem:
var configUrl = ConfigurationManager.AppSettings.Get("Url");
var mobileFormControl = Page.FindControl("mobileForm")
as System.Web.UI.MobileControls.Form;
if(configUrl != null && mobileFormControl != null)
{
img1.ImageUrl = configUrl.Replace("###", randomString) + mobileControl.Title;
}
It's VERY important to include:
