Usage: You can simply get the device model with:
let deviceType = UIDevice().type
or print the exact string with:
print("Running on: \(UIDevice().type)")
Output -> "iPhone X"
Another example with cases:
var myDefaultFontSize: CGFloat = 26.0
switch UIDevice().type {
case .iPhoneSE, .iPhone5, .iPhone5S: print("default value")
case .iPhone6, .iPhone7, .iPhone8, .iPhone6S, .iPhoneX: myDefaultFontSize += 4
default: break
}

For me this works on Desktop, IOS and Android.
I created my AppIcon catalog manually and had all the correct icons in it, but my project was not using it as the icon catalog. On the project's General tab (where you can set the project name and version number), there was an entry for App Icons Source, but no way to select the catalog I created. I had to click the button to create a new catalog, then delete that new catalog, and then the button changed to a menu where I could select the existing catalog.
Here is a very slight improvement to user1387483's answer using an immediate function:
(function() {
$("*").on( 'touchstart', function() {
$(this).trigger('hover') ;
} ).on('touchend', function() {
$(this).trigger('hover') ;
} ) ;
})() ;
Also, I agree with Boz that this appears to be the "neatest, most compliant solution".
Since you installed a new OS you probably don't have any more of your private and public keys that you used to sign your app in to XCode before. You need to regenerate those keys on your machine by revoking your previous certificate and asking for a new one on the iOS development portal. As part of the process you will be asked to generate a Certificate Signing Request which is where you seem to have a problem.
You will find all you need there which consists of (from the official doc):
1.Open Keychain Access on your Mac (located in Applications/Utilities).
2.Open Preferences and click Certificates. Make sure both Online Certificate Status Protocol and Certificate Revocation List are set to Off.
3.Choose Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority.
Note: If you have a private key selected when you do this, the CSR won’t be accepted. Make sure no private key is selected. Enter your user email address and common name. Use the same address and name as you used to register in the iOS Developer Program. No CA Email Address is required.
4.Select the options “Saved to disk” and “Let me specify key pair information” and click Continue.
5.Specify a filename and click Save. (make sure to replace .certSigningRequest with .csr)
For the Key Size choose 2048 bits and for Algorithm choose RSA. Click Continue and the Certificate Assistant creates a CSR and saves the file to your specified location.
Below is the code for that (code may not contain all device's string, I'm with other guys are maintaining the same code on GitHub so please take the latest code from there)
Objective-C : GitHub/DeviceUtil
Swift : GitHub/DeviceGuru
#include <sys/types.h>
#include <sys/sysctl.h>
- (NSString*)hardwareDescription {
NSString *hardware = [self hardwareString];
if ([hardware isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";
if ([hardware isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
if ([hardware isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
if ([hardware isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
if ([hardware isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
if ([hardware isEqualToString:@"iPod1,1"]) return @"iPodTouch 1G";
if ([hardware isEqualToString:@"iPod2,1"]) return @"iPodTouch 2G";
if ([hardware isEqualToString:@"iPad1,1"]) return @"iPad";
if ([hardware isEqualToString:@"iPad2,6"]) return @"iPad Mini";
if ([hardware isEqualToString:@"iPad4,1"]) return @"iPad Air WIFI";
//there are lots of other strings too, checkout the github repo
//link is given at the top of this answer
if ([hardware isEqualToString:@"i386"]) return @"Simulator";
if ([hardware isEqualToString:@"x86_64"]) return @"Simulator";
return nil;
}
- (NSString*)hardwareString {
size_t size = 100;
char *hw_machine = malloc(size);
int name[] = {CTL_HW,HW_MACHINE};
sysctl(name, 2, hw_machine, &size, NULL, 0);
NSString *hardware = [NSString stringWithUTF8String:hw_machine];
free(hw_machine);
return hardware;
}
For the latest versions of iOS, simply add UITraitCollection
:
extension UITraitCollection {
var isIpad: Bool {
return horizontalSizeClass == .regular && verticalSizeClass == .regular
}
}
and then within UIViewController
just check:
if traitCollection.isIpad { ... }
Try this instead
SELECT MAX(shoppername), COUNT(*) AS cnt
FROM dbo.sales
GROUP BY CHECKSUM(*)
HAVING COUNT(*) > 1
Read about the CHECKSUM function first, as there can be duplicates.
All a [self.navigationController pushViewController:controller animated:YES];
does is animate a transition, and add it to the navigation controller stack, and some other cool navigation bar animation stuffs. If you don't care about the bar animation, then this code should work. The bar does appear on the new controller, and you get an interactive pop gesture!
//Make Controller
DetailViewController *controller = [[DetailViewController alloc] initWithNibName:nil
bundle:[NSBundle mainBundle]];
//Customize presentation
controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
controller.modalPresentationStyle = UIModalPresentationCurrentContext;
//Present controller
[self presentViewController:controller
animated:YES
completion:nil];
//Add to navigation Controller
[self navigationController].viewControllers = [[self navigationController].viewControllers arrayByAddingObject:controller];
//You can't just [[self navigationController].viewControllers addObject:controller] because viewControllers are for some reason not a mutable array.
Edit: Sorry, presentViewController will fill the full screen. You will need to make a custom transition, with CGAffineTransform.translation or something, animate the controller with the transition, then add it to the navigationController's viewControllers.
Try the freeware iOS Console. Just download, launch, connect your device -- et voila!
Changed the
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=API">
function(){
myMap()
}
</script>
and made it
<script type="text/javascript">
function(){
myMap()
}
</script>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=API"></script>
It worked :)
Results of testing with the utility Split wrote (link is in his answer):
device: (crash amount/total amount/percentage of total)
The above answer for webkit appearance worked, but the button still looked kind pale/dull compared to the browser on other devices/desktop. I also had to set opacity to full (ranges from 0 to 1)
-webkit-appearance:none;
opacity: 1
After setting the opacity, the button looked the same on all the different devices/emulator/desktop.
I'm pretty new to iOS and Phonegap as well, but I was able to do this by adding in an eventListener. I did the same thing (using the example you reference), and couldn't get it to work. But this seemed to do the trick:
// Event listener to determine change (horizontal/portrait)
window.addEventListener("orientationchange", updateOrientation);
function updateOrientation(e) {
switch (e.orientation)
{
case 0:
// Do your thing
break;
case -90:
// Do your thing
break;
case 90:
// Do your thing
break;
default:
break;
}
}
You may have some luck searching the PhoneGap Google Group for the term "orientation".
One example I read about as an example on how to detect orientation was Pie Guy: (game, js file). It's similar to the code you've posted, but like you... I couldn't get it to work.
One caveat: the eventListener worked for me, but I'm not sure if this is an overly intensive approach. So far it's been the only way that's worked for me, but I don't know if there are better, more streamlined ways.
UPDATE fixed the code above, it works now
The JailCoder references above point to a site that does not exist any more. Looks like you should use http://oneiros.altervista.org/jailcoder/ or https://www.facebook.com/jailcoder
I had this problem too. I just set my deployment target to 4.3 and left only armv7 architecture and it worked. At point almost everyone has 5, so 4.3 is fine.
Apple lifted the restrictions on non-Objective C/C/C++ apps -- you just can't load code that isn't in the app bundle.
MonoTouch lets you use .NET languages -- C# is directly supported, but if you have Windows, you can make assemblies in any .NET language and use it.
There are rumors that Apple is going to support other languages directly -- I keep hearing ruby, but they are just rumors.
I think Lua is being used for game logic on a lot of apps.
EDIT (in 2018): Generally you can use any language that you can get to compile for iOS or even install language interpreters. The main thing you cannot do is load code from the Internet that wasn't in the app bundle.
People do this all of the time anyway (see React Native apps loading JavaScript from servers), but, technically, it's not allowed. The main thing that will get you attention from Apple if you make some kind of App Store that loads whole App-like things.
EDIT (in 2020): from @Pylot in comments: I know this is a long time ago, but now at least technically you can load code that isn’t embedded in the app, as you can write with JavaScript using the webview. Not staying your answer is wrong or anything, I definitely agree with you. but I was looking for something and found this post on the way. Figured if anyone sees this it might help them out.
I think it is worth mentioning that you don't generally need to use the whole agent string, unless perhaps you find a reason where you need to tailor the website to a specific model.
You can check for iPhone, iPad and iPod in the agent string and cover all your bases.
if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)) || (navigator.userAgent.match(/iPad/i))) {
appleMobileDevice = true;
}
else {
appleMobileDevice = false;
}
Here's a simpler solution that worked for me and which doesn't require the manual editing of the project file:
In Xcode, in the "Groups & Files" pane, expand "Targets" and double-click on your app's target. This brings up the Info pane for the target. In the "Build" section, check the "code signing" section for any old profiles and replace with the correct one.
Note that this is different from double-clicking on your project icon and changing the profile from there. Quite amazing :)

}
If injecting multiple script tags in the head like this with mix of local and remote script files a situation may arise where the local scripts that are dependent on external scripts (such as loading jQuery from googleapis) will have errors because the external scripts may not be loaded before the local ones are.
So something like this would have a problem: ("jQuery is not defined" in jquery.some-plugin.js).
var head = document.getElementsByTagName('head')[0];
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = "https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js";
head.appendChild(script);
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = "/jquery.some-plugin.js";
head.appendChild(script);
Of course this situation is what the .onload() is for, but if multiple scripts are being loaded that can be cumbersome.
As a resolution to this situation, I put together this function that will keep a queue of scripts to be loaded, loading each subsequent item after the previous finishes, and returns a Promise that resolves when the script (or the last script in the queue if no parameter) is done loading.
load_script = function(src) {
// Initialize scripts queue
if( load_script.scripts === undefined ) {
load_script.scripts = [];
load_script.index = -1;
load_script.loading = false;
load_script.next = function() {
if( load_script.loading ) return;
// Load the next queue item
load_script.loading = true;
var item = load_script.scripts[++load_script.index];
var head = document.getElementsByTagName('head')[0];
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = item.src;
// When complete, start next item in queue and resolve this item's promise
script.onload = () => {
load_script.loading = false;
if( load_script.index < load_script.scripts.length - 1 ) load_script.next();
item.resolve();
};
head.appendChild(script);
};
};
// Adding a script to the queue
if( src ) {
// Check if already added
for(var i=0; i < load_script.scripts.length; i++) {
if( load_script.scripts[i].src == src ) return load_script.scripts[i].promise;
}
// Add to the queue
var item = { src: src };
item.promise = new Promise(resolve => {item.resolve = resolve;});
load_script.scripts.push(item);
load_script.next();
}
// Return the promise of the last queue item
return load_script.scripts[ load_script.scripts.length - 1 ].promise;
};
With this adding scripts in order ensuring the previous are done before staring the next can be done like...
["https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js",
"/jquery.some-plugin.js",
"/dependant-on-plugin.js",
].forEach(load_script);
Or load the script and use the return Promise to do work when it's complete...
load_script("some-script.js")
.then(function() {
/* some-script.js is done loading */
});
try like this
<?php
if(your condition){
echo "<script> window.onload = function() {
yourJavascriptFunction(param1, param2);
}; </script>";
?>
The suggested causes are now proven to be mostly impossible. I'm running SSMS V17.9.2 against SS 2014 and still have the problem. Memory problems have existed with this tool since at least 2006 when I started using SSMS.
Yes, MS 'wants' to get rid of diagramming but users won't let them. I have a feeling they will never fix any of these issues because they want users to be so fed up with the tool that enough of them quit using it and they can abandon it entirely.
Restarting is still a workaround if you can stand doing so numerous times per day.
At least in the current versions of PHPMailers, there's a function clearReplyTos() to empty the reply-to array.
$mail->ClearReplyTos();
$mail->addReplyTo([email protected], 'EXAMPLE');
Be sure to have both objects created in controller: @post
and @comment
for the post, eg:
@post = Post.find params[:post_id]
@comment = Comment.new(:post=>@post)
Then in view:
<%= form_for([@post, @comment]) do |f| %>
Be sure to explicitly define the array in the form_for, not just comma separated like you have above.
Another example using PowerShell for set permissions (File / Directory) :
Get-Acl "C:\file.txt" | fl *
$acl = Get-Acl "C:\file.txt"
$accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule("everyone","FullControl","Allow")
$acl.SetAccessRule($accessRule)
$acl | Set-Acl "C:\file.txt"
Hope this helps
Why not check for what the user entered and then ask the user to enter correct input again?
eg:
//Get player's play from input-- note that this is
// stored as a string
System.out.println("Enter your play: ");
response = scan.next();
if(response=="R"||response=="P"||response=="S"){
personPlay = response;
}else{
System.out.println("Invaild Input")
}
for the other modifications, please check my total code at pastebin
Arrays.asList("Ryan", "Julie", "Bob");
In Python 2.x, you would do
isinstance(s, basestring)
basestring
is the abstract superclass of str
and unicode
. It can be used to test whether an object is an instance of str
or unicode
.
In Python 3.x, the correct test is
isinstance(s, str)
The bytes
class isn't considered a string type in Python 3.
Try localhost
instead of 127.0.0.1
to connect or in your connection-config
. Worked for me on a Debian Squeeze Server
SELECT * FROM `table_name`
ORDER BY `table_name`.`column_name` DESC
LIMIT 1
It's safe to increase the size of your varchar column. You won't corrupt your data.
If it helps your peace of mind, keep in mind, you can always run a database backup before altering your data structures.
By the way, correct syntax is:
ALTER TABLE table_name MODIFY col_name VARCHAR(10000)
Also, if the column previously allowed/did not allow nulls, you should add the appropriate syntax to the end of the alter table statement, after the column type.
My solution is to run twine upload
over the python -m
argument.
So just use python -m

This might help someone like me that finds this answer when searching for solutions to how Rails handles the class loading ... I found that I had to define a module
whose name matched my filename appropriately, rather than just defining a class:
In file lib/development_mail_interceptor.rb (Yes, I'm using code from a Railscast :))
module DevelopmentMailInterceptor
class DevelopmentMailInterceptor
def self.delivering_email(message)
message.subject = "intercepted for: #{message.to} #{message.subject}"
message.to = "[email protected]"
end
end
end
works, but it doesn't load if I hadn't put the class inside a module.
I don't see either MacPorts or Homebrew mentioned in other answers here, but since I do see them mentioned elsewhere on Stack Overflow for related questions, I'll add my own US$0.02 that many folks seem to consider MacPorts as not only a package manager for packages in general (as of today they list 16311 packages/ports, 2931 matching "python", albeit only for Macs), but also as a decent (maybe better) package manager for Python packages/modules:
"...what is the method that Mac python developers use to manage their modules?"
I'm still debating on whether or not to use MacPorts myself, but at the moment I'm leaning in that direction.
Use following hexadecimal code for transparent text colour: #00FFFF00
Unlimited string readed:
String content = "";
char character;
while(Serial.available()) {
character = Serial.read();
content.concat(character);
}
if (content != "") {
Serial.println(content);
}
This is probably how you should do it:
void push(std::string&& filename)
{
{
std::lock_guard<std::mutex> lock(qMutex);
q.push(std::move(filename));
}
populatedNotifier.notify_one();
}
bool try_pop(std::string& filename, std::chrono::milliseconds timeout)
{
std::unique_lock<std::mutex> lock(qMutex);
if(!populatedNotifier.wait_for(lock, timeout, [this] { return !q.empty(); }))
return false;
filename = std::move(q.front());
q.pop();
return true;
}

}
}
boolean checkInternet(Context context) {
ServiceManager serviceManager = new ServiceManager(context);
if (serviceManager.isNetworkAvailable()) {
return true;
} else {
return false;
}
}
}
ServiceManager.java
public class ServiceManager {
Context context;
public ServiceManager(Context base) {
context = base;
}
public boolean isNetworkAvailable() {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = cm.getActiveNetworkInfo();
return networkInfo != null && networkInfo.isConnected();
}
}
In this case you need to go up to the <tr>
then use .next()
, like this:
$(obj).closest('tr').next().find('.class');
Or if there may be rows in-between without the .class
inside, you can use .nextAll()
, like this:
$(obj).closest('tr').nextAll(':has(.class):first').find('.class');
In Oracle the location that contains information about all database objects including tables and stored procedures is called the Data Dictionary. It is a collection of views that provides you with access to the metadata that defines the database. You can query the Data Dictionary views for a list of desired database objects and then use the functions available in dbms_metadata
package to get the DDL for each object. Alternative is to investigate the support in dbms_metadata
to export DDLs for a collection of objects.
For a few pointers, for example to get a list of tables you can use the following Data Dictionary views
user_tables
contains all tables owned by the userall_tables
contains all tables that are accessible by the userHere's a function I wrote another application. Feel free to reuse:
function writeCookie (key, value, days) {
var date = new Date();
// Default at 365 days.
days = days || 365;
// Get unix milliseconds at current time plus number of days
date.setTime(+ date + (days * 86400000)); //24 * 60 * 60 * 1000
window.document.cookie = key + "=" + value + "; expires=" + date.toGMTString() + "; path=/";
return value;
};

RPC is C based, and as such it has structured programming semantics, on the other side, RMI is a Java based technology and it's object oriented.
With RPC you can just call remote functions exported into a server, in RMI you can have references to remote objects and invoke their methods, and also pass and return more remote object references that can be distributed among many JVM instances, so it's much more powerful.
RMI stands out when the need to develop something more complex than a pure client-server architecture arises. It's very easy to spread out objects over a network enabling all the clients to communicate without having to stablish individual connections explicitly.
From this MSDN article:
There is some overhead associated with creating a StringBuilder object, both in time and memory. On a machine with fast memory, a StringBuilder becomes worthwhile if you're doing about five operations. As a rule of thumb, I would say 10 or more string operations is a justification for the overhead on any machine, even a slower one.
So if you trust MSDN go with StringBuilder if you have to do more than 10 strings operations/concatenations - otherwise simple string concat with '+' is fine.
Your append line must be in your test()
function
EDIT:
Here are two versions:
Version 1: jQuery listener
$(function(){
$('button').on('click',function(){
var r= $('<input type="button" value="new button"/>');
$("body").append(r);
});
});
Version 2: With a function (like your example)
function createInput(){
var $input = $('<input type="button" value="new button" />');
$input.appendTo($("body"));
}
Note: This one can be done with either .appendTo
or with .append
.
Had a similar problem to yours. What we had to do is use the document.domain solution found here:
Ways to circumvent the same-origin policy
We also needed to change thins on the web service side. Used the "Access-Control-Allow-Origin" header found here:
to select records for the last 7 days
WHERE Created_Date >= DATEADD(day, -7, GETDATE())
to select records for the current week
SET DATEFIRST 1 -- Define beginning of week as Monday
SELECT * FROM
WHERE CreatedDate >= DATEADD(day, 1 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE()))
AND CreatedDate < DATEADD(day, 8 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE()))
if you want to select records for last week instead of the last 7 days
SET DATEFIRST 1 -- Define beginning of week as Monday
SELECT * FROM
WHERE CreatedDate >= DATEADD(day, -(DATEPART(dw, GETDATE()) + 6), CONVERT(DATE, GETDATE()))
AND CreatedDate < DATEADD(day, 1 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE()))
It is possible to start an app's activity by using Intent.setClassName
according to the docs.
An example:
val activityName = "com.google.android.apps.muzei.MuzeiActivity" // target activity name
val packageName = "net.nurik.roman.muzei" // target package's name
val intent = Intent().setClassName(packageName, activityName)
startActivity(intent)
To open it outside the current app, add this flag before starting the intent.
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)

In my case I wasn't sure what had caused this to happen, but I knew I just wanted the submodules to be reset to their latest remote commit and be done with it. This involved combining answers from a couple of different questions on here:

You can use this simple plugin as $('#some_id').getAttributes();
(function($) {
$.fn.getAttributes = function() {
var attributes = {};
if( this.length ) {
$.each( this[0].attributes, function( index, attr ) {
attributes[ attr.name ] = attr.value;
} );
}
return attributes;
};
})(jQuery);
Just another recommendation. The plugin Purl allows to retrieve all parts of URL, including anchor, host, etc.
It can be used with or without jQuery.
Usage is very simple and cool:
var url = $.url('http://allmarkedup.com/folder/dir/index.html?item=value'); // jQuery version
var url = purl('http://allmarkedup.com/folder/dir/index.html?item=value'); // plain JS version
url.attr('protocol'); // returns 'http'
url.attr('path'); // returns '/folder/dir/index.html'
However, as of Nov 11, 2014, Purl is no longer maintained and the author recommends using URI.js instead. The jQuery plugin is different in that it focuses on elements - for usage with strings, just use URI
directly, with or without jQuery. Similar code would look as such, fuller docs here:
var url = new URI('http://allmarkedup.com/folder/dir/index.html?item=value'); // plain JS version
url.protocol(); // returns 'http'
url.path(); // returns '/folder/dir/index.html'
Maybe you want set -e
:
www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:
This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.

In the code with variables, the variable created with class, NSString was outputted be NSLog. The %@ represents text as a variable.

You will need to cast
or convert
as a CHAR
datatype, there is no varchar
datatype that you can cast/convert data to:
select CAST(id as CHAR(50)) as col1
from t9;
select CONVERT(id, CHAR(50)) as colI1
from t9;
See the following SQL — in action — over at SQL Fiddle:
/*! Build Schema */
create table t9 (id INT, name VARCHAR(55));
insert into t9 (id, name) values (2, 'bob');
/*! SQL Queries */
select CAST(id as CHAR(50)) as col1 from t9;
select CONVERT(id, CHAR(50)) as colI1 from t9;
Besides the fact that you were trying to convert to an incorrect datatype, the syntax that you were using for convert
was incorrect. The convert
function uses the following where expr
is your column or value:
CONVERT(expr,type)
or
CONVERT(expr USING transcoding_name)
Your original query had the syntax backwards.
The Saxon documentation, though a little unclear, seems to suggest that the JAXP XPath API will return false
when evaluating an XPath expression if no matching nodes are found.
This IBM article mentions a return value of null
when no nodes are matched.
You might need to play around with the return types a bit based on this API, but the basic idea is that you just run a normal XPath and check whether the result is a node / false
/ null
/ etc.
XPathFactory xpathFactory = XPathFactory.newInstance(NamespaceConstant.OBJECT_MODEL_SAXON);
XPath xpath = xpathFactory.newXPath();
XPathExpression expr = xpath.compile("/Consumers/Consumer/DataSources/Credit/CreditReport/AttachedXml");
Object result = expr.evaluate(doc, XPathConstants.NODE);
if ( result == null ) {
// do something
}
If you want the view to be read only after granting the read permission you can use the ALGORITHM = TEMPTABLE in you view DDL definition.
I had the same problem for a GitHub repository. My account was missing SSH Key. The process is
Then, you can clone the repository with submodules (git clone --recursive YOUR-GIT-REPO-URL
)
or
Run git submodule init
and git submodule update
to fetch submodules in already cloned repository.
You can use $query->getSingleResult()
, which will throw an exception if more than one result are found, or if no result is found. (see the related phpdoc here https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/AbstractQuery.php#L791)
There's also the less famous $query->getOneOrNullResult()
which will throw an exception if more than one result are found, and return null if no result is found. (see the related phpdoc here https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/AbstractQuery.php#L752)
One can think of document.write() (and .innerHTML) as evaluating a source code string. This can be very handy for many applications. For example if you get HTML code as a string from some source, it is handy to just "evaluate" it.
In the context of Lisp, DOM manipulation would be like manipulating a list structure, e.g. create the list (orange) by doing:
(cons 'orange '())
And document.write() would be like evaluating a string, e.g. create a list by evaluating a source code string like this:
(eval-string "(cons 'orange '())")
Lisp also has the very useful ability to create code using list manipulation (like using the "DOM style" to create a JS parse tree). This means you can build up a list structure using the "DOM style", rather than the "string style", and then run that code, e.g. like this:
(eval '(cons 'orange '()))
If you implement coding tools, like simple live editors, it is very handy to have the ability to quickly evaluate a string, for example using document.write() or .innerHTML. Lisp is ideal in this sense, but you can do very cool stuff also in JS, and many people are doing that, like http://jsbin.com/
try this command :
ng --version
It prints out Angular, Angular CLI, Node, Typescript versions etc.
No, it sets all members/elements that haven't been explicitly set to their default-initialisation value, which is zero for numeric types.
I prefer using function pointers over gigantic switch
statements, but in contrast to qrdl's answer I normally don't use explicit return codes or transition tables.
Also, in most cases you'll want a mechanism to pass along additional data. Here's an example state machine:
#include <stdio.h>
struct state;
typedef void state_fn(struct state *);
struct state
{
state_fn * next;
int i; // data
};
state_fn foo, bar;
void foo(struct state * state)
{
printf("%s %i\n", __func__, ++state->i);
state->next = bar;
}
void bar(struct state * state)
{
printf("%s %i\n", __func__, ++state->i);
state->next = state->i < 10 ? foo : 0;
}
int main(void)
{
struct state state = { foo, 0 };
while(state.next) state.next(&state);
}
You can check it with for example jQuery:
$("#elementID").css('display');
It will return string with information about display property of this element.
In practice, it is O(1), but this actually is a terrible and mathematically non-sense simplification. The O() notation says how the algorithm behaves when the size of the problem tends to infinity. Hashmap get/put works like an O(1) algorithm for a limited size. The limit is fairly large from the computer memory and from the addressing point of view, but far from infinity.
When one says that hashmap get/put is O(1) it should really say that the time needed for the get/put is more or less constant and does not depend on the number of elements in the hashmap so far as the hashmap can be presented on the actual computing system. If the problem goes beyond that size and we need larger hashmaps then, after a while, certainly the number of the bits describing one element will also increase as we run out of the possible describable different elements. For example, if we used a hashmap to store 32bit numbers and later we increase the problem size so that we will have more than 2^32 bit elements in the hashmap, then the individual elements will be described with more than 32bits.
The number of the bits needed to describe the individual elements is log(N), where N is the maximum number of elements, therefore get and put are really O(log N).
If you compare it with a tree set, which is O(log n) then hash set is O(long(max(n)) and we simply feel that this is O(1), because on a certain implementation max(n) is fixed, does not change (the size of the objects we store measured in bits) and the algorithm calculating the hash code is fast.
Finally, if finding an element in any data structure were O(1) we would create information out of thin air. Having a data structure of n element I can select one element in n different way. With that, I can encode log(n) bit information. If I can encode that in zero bit (that is what O(1) means) then I created an infinitely compressing ZIP algorithm.
You can use try-catch block to check for integer value
for eg:
User inputs in form of string
try
{
int num=Integer.parseInt("Some String Input");
}
catch(NumberFormatException e)
{
//If number is not integer,you wil get exception and exception message will be printed
System.out.println(e.getMessage());
}
Your html is not updated every 15 seconds. The cause could be browser caching. Add Math.random()
to avoid browser caching, and it's better to wait until the DOM is fully loaded as pointed out by @shadow. But I think the main cause is the caching
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js" />
<script type="text/javascript">
$(document).ready(function(){
var auto_refresh = setInterval(
function ()
{
$('.View').load('Small.php?' + Math.random()).fadeIn("slow");
}, 15000); // refresh every 15000 milliseconds
});
</script>

after every startup it will run the test script.
The way I solved this, which is another option (if you have jQuery available), was to Define the fields in an old-school object and then extend the class with that object. I also didn't want to pepper the constructor with assignments, this appeared to be a neat solution.
function MyClassFields(){
this.createdAt = new Date();
}
MyClassFields.prototype = {
id : '',
type : '',
title : '',
createdAt : null,
};
class MyClass {
constructor() {
$.extend(this,new MyClassFields());
}
};
-- Update Following Bergi's comment.
No JQuery Version:
class SavedSearch {
constructor() {
Object.assign(this,{
id : '',
type : '',
title : '',
createdAt: new Date(),
});
}
}
You still do end up with 'fat' constructor, but at least its all in one class and assigned in one hit.
EDIT #2: I've now gone full circle and am now assigning values in the constructor, e.g.
class SavedSearch {
constructor() {
this.id = '';
this.type = '';
this.title = '';
this.createdAt = new Date();
}
}
Why? Simple really, using the above plus some JSdoc comments, PHPStorm was able to perform code completion on the properties. Assigning all the vars in one hit was nice, but the inability to code complete the properties, imo, isn't worth the (almost certainly minuscule) performance benefit.
Using printf
you can do
printf("Here are the first 8 chars: %.8s\n", "A string that is more than 8 chars");
If you're using C++, you can achieve the same result using the STL:
using namespace std; // for clarity
string s("A string that is more than 8 chars");
cout << "Here are the first 8 chars: ";
copy(s.begin(), s.begin() + 8, ostream_iterator<char>(cout));
cout << endl;
Or, less efficiently:
cout << "Here are the first 8 chars: " <<
string(s.begin(), s.begin() + 8) << endl;
The Array index only accepts a long value.
You declared iCounter as an integer. You should declare it as a long.

public class Sent
{
public int MsgID;
public string Content;
public int Status;

public class Messages

public int MsgID;
public string Content;
}
List<Sent> SentList = new List<Sent>() { new Sent() { MsgID = 1, Content = "aaa", Status = 0 }, new Sent() { MsgID = 3, Content = "ccc", Status = 0 } };
List<Messages> MsgList = new List<Messages>() { new Messages() { MsgID = 1, Content = "aaa" }, new Messages() { MsgID = 2, Content = "bbb" }, new Messages() { MsgID = 3, Content = "ccc" }, new Messages() { MsgID = 4, Content = "ddd" }, new Messages() { MsgID = 5, Content = "eee" }};
int [] sentMsgIDs = SentList.Select(v => v.MsgID).ToArray();
List<Messages> result1 = MsgList.Where(o => !sentMsgIDs.Contains(o.MsgID)).ToList<Messages>();
Hope it should help.

As of NumPy 1.13, one can simply choose the axis for selection of unique values in any N-dim array. To get unique rows, one can do:
unique_rows = np.unique(original_array, axis=0)
An array can be loaded in twoways.
set -A TEST_ARRAY alpha beta gamma
or
X=0 # Initialize counter to zero.
-- Load the array with the strings alpha, beta, and gamma
for ELEMENT in alpha gamma beta
do
TEST_ARRAY[$X]=$ELEMENT
((X = X + 1))
done
Also, I think below information may help:
The shell supports one-dimensional arrays. The maximum number of array elements is 1,024. When an array is defined, it is automatically dimensioned to 1,024 elements. A one-dimensional array contains a sequence of array elements, which are like the boxcars connected together on a train track.
In case you want to access the array:
echo ${MY_ARRAY[2] # Show the third array element
gamma
echo ${MY_ARRAY[*] # Show all array elements
- alpha beta gamma
echo ${MY_ARRAY[@] # Show all array elements
- alpha beta gamma
echo ${#MY_ARRAY[*]} # Show the total number of array elements
- 3
echo ${#MY_ARRAY[@]} # Show the total number of array elements
- 3
echo ${MY_ARRAY} # Show array element 0 (the first element)
- alpha
maybe you forget to add parameter dataType:'json' in your $.ajax
$.ajax({
type: "POST",
dataType: "json",
url: url,
data: { get_member: id },
success: function( response )
{
//some action here
},
error: function( error )
{
alert( error );
}
});
With PostgreSQL 9.1 this can be achieved using a writeable CTE (common table expression):
WITH new_values (id, field1, field2) as (
values
(1, 'A', 'X'),
(2, 'B', 'Y'),
(3, 'C', 'Z')
),
upsert as
(
update mytable m
set field1 = nv.field1,
field2 = nv.field2
FROM new_values nv
WHERE m.id = nv.id
RETURNING m.*
)
INSERT INTO mytable (id, field1, field2)
SELECT id, field1, field2
FROM new_values
WHERE NOT EXISTS (SELECT 1
FROM upsert up
WHERE up.id = new_values.id)

If you can compute a unique integer for each element in the array, like this:
tab='0123456789abcdefghijklmnopqrstuvwxyz'
# build the reversed ordinal map
for ((i = 0; i < ${#tab}; i++)); do
declare -g ord_${tab:i:1}=$i
done
function sexy_int() {
local sum=0
local i ch ref
for ((i = 0; i < ${#1}; i++)); do
ch="${1:i:1}"
ref="ord_$ch"
(( sum += ${!ref} ))
done
return $sum
}
sexy_int hello
echo "hello -> $?"
sexy_int world
echo "world -> $?"
then, you can use these integers as array indexes, because Bash always use sparse array, so no need to worry about unused indexes:
array=(a c b f 3 5)
for el in "${array[@]}"; do
sexy_int "$el"
sorted[$?]="$el"
done
echo "${sorted[@]}"
Conditions using Array:
$users = User::where([
'column1' => value1,
'column2' => value2,

Conditions using Anonymous Function:
$users = User::where('column1', '=', value1)

This is great!
You could simply use the modulo operation (MOD or % in mysql) to make your code simple at the end:
Instead of:
AND (
( CASE ( 1299132000 - EM1.`meta_value` )
WHEN 0
THEN 1
ELSE ( 1299132000 - EM1.`meta_value` )
END
) / EM2.`meta_value`
) = 1
Do:
$current_timestamp = 1299132000 ;
AND ( ('$current_timestamp' - EM1.`meta_value` ) MOD EM2.`meta_value`) = 1")
To take this further, one could include events that do not recur for ever.
Something like "repeat_interval_1_end" to denote the date of the last "repeat_interval_1" could be added. This however, makes the query more complicated and I can't really figure out how to do this ...
Maybe someone could help!
SELECT DATE_FORMAT(somedate, "%d/%m/%Y") AS formatted_date
..........
ORDER BY formatted_date DESC
Parenthesis ()
are used to enable grouping of regex phrases.
The group(1)
contains the string that is between parenthesis (.*)
so .*
in this case
And group(0)
contains whole matched string.
If you would have more groups (read (...)
) it would be put into groups with next indexes (2, 3 and so on).
I just press enter and type Pause and it works fine
I had the same problem while designing a template in Mailjet. Solution of the problem was minified CSS code inside <style>
tags.
Maybe you should try removing "new" keyword and see if works.
Because last time I got this error when I tried creating Typeface
something like this:
Typeface typeface = new Typeface().create("Arial",Typeface.BOLD);
The above solutions were not working for me. I solved it by creating a View with the same background colour as the parent and added negative margin to move the image upwards.
<ScrollView style={{ backgroundColor: 'blue' }}>
<View
style={{
width: '95%',
paddingLeft: '5%',
marginTop: 80,
height: 800,
}}>
<View style={{ backgroundColor: 'white' }}>
<Thumbnail square large source={{uri: uri}} style={{ marginTop: -30 }}/>
<Text>Some Text</Text>
</View>
</View>
</ScrollView>
and I got the following result.
I am receiving the data from a web-service that sends NaN
as a string 'Nan'
. But there could be other sorts of string in my data as well, so a simple float(value)
could throw an exception. I used the following variant of the accepted answer:
def isnan(value):
try:
import math
return math.isnan(float(value))
except:
return False
Requirement:
isnan('hello') == False
isnan('NaN') == True
isnan(100) == False
isnan(float('nan')) = True
It is similar to BVB Media's answer.

To whitelist an entire hash of parameters, the permit! method can be used
params.require(:log_entry).permit!
Nested attributes are in the form of a hash. In my app, I have a Question.rb model accept nested attributes for an Answer.rb model (where the user creates answer choices for a question he creates). In the questions_controller, I do this
def question_params
params.require(:question).permit!
end
Everything in the question hash is permitted, including the nested answer attributes. This also works if the nested attributes are in the form of an array.
Having said that, I wonder if there's a security concern with this approach because it basically permits anything that's inside the hash without specifying exactly what it is, which seems contrary to the purpose of strong parameters.
You can do this:
<div class"my_class">
<?php if ($cart->count_product > 0) {
print $cart->count_product;
} else {
print '';
}
?>
</div>

This is caused by an incompatibility with the android support library that changed to version 28. I solved the problem by forcing the build to use a lower support library. //like build gradle
configurations.all {
resolutionStrategy {
force 'com.android.support:support-v4:27.1.0'
}
}
My project built successfully immediately after I changed this. Hope this might help you too. I lost a day of development because of this!.
You don't need to store the column to reference it that way. Try this:
To set up:
CREATE TABLE tbl
(zipcode text NOT NULL, city text NOT NULL, state text NOT NULL);
INSERT INTO tbl VALUES ('10954', 'Nanuet', 'NY');
We can see we have "the right stuff":
\pset border 2
SELECT * FROM tbl;
+---------+--------+-------+ | zipcode | city | state | +---------+--------+-------+ | 10954 | Nanuet | NY | +---------+--------+-------+
Now add a function with the desired "column name" which takes the record type of the table as its only parameter:
CREATE FUNCTION combined(rec tbl)
RETURNS text
LANGUAGE SQL
AS $$
SELECT $1.zipcode || ' - ' || $1.city || ', ' || $1.state;
$$;
This creates a function which can be used as if it were a column of the table, as long as the table name or alias is specified, like this:
SELECT *, tbl.combined FROM tbl;
Which displays like this:
+---------+--------+-------+--------------------+ | zipcode | city | state | combined | +---------+--------+-------+--------------------+ | 10954 | Nanuet | NY | 10954 - Nanuet, NY | +---------+--------+-------+--------------------+
This works because PostgreSQL checks first for an actual column, but if one is not found, and the identifier is qualified with a relation name or alias, it looks for a function like the above, and runs it with the row as its argument, returning the result as if it were a column. You can even index on such a "generated column" if you want to do so.
Because you're not using extra space in each row for the duplicated data, or firing triggers on all inserts and updates, this can often be faster than the alternatives.
This worked for me in Firefox and Chrome and IE8...

//get and format the path pointing to the internal storage

If you're creating hundreds of thousands of hash maps, you're probably using far more than you actually need; unless you're working with large files or graphics, storing simple data shouldn't overflow the Java memory limit.
You should try and rethink your algorithm. In this case, I would offer more help on that subject, but I can't give any information until you provide more about the context of the problem.
There is a good way if you use validate()

Maybe it's the way I read this but assuming the excel sheet 1 is called "London" and has this information; B5="Marleybone" B6="Paddington" B7="Victoria" B8="Hammersmith". And the excel sheet 2 is called "Nottingham" and has this information; C5="Alverton" C6="Annesley" C7="Arnold" C8="Askham". Then I think this code below would work. ^_^
$xlCellTypeLastCell = 11
$startRow = 5
$excel = new-object -com excel.application
$wb = $excel.workbooks.open("C:\users\administrator\my_test.xls")
for ($i = 1; $i -le $wb.sheets.count; $i++)
{
$sh = $wb.Sheets.Item($i)
$endRow = $sh.UsedRange.SpecialCells($xlCellTypeLastCell).Row
$col = $col + $i - 1
$city = $wb.Sheets.Item($i).name
$rangeAddress = $sh.Cells.Item($startRow, $col).Address() + ":" + $sh.Cells.Item($endRow, $col).Address()
$sh.Range($rangeAddress).Value2 | foreach{
New-Object PSObject -Property @{City = $city; Area=$_}
}
}
$excel.Workbooks.Close()
This should be the output (without the commas):
City, Area

Your command is completely incorrect. The output format is not rawvideo
and you don't need the bitstream filter h264_mp4toannexb
which is used when you want to convert the h264
contained in an mp4
to the Annex B
format used by MPEG-TS
for example. What you want to use instead is the aac_adtstoasc
for the AAC
streams.
ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4
have at look at the static methods DateTime.Parse()
and DateTime.TryParse()
. They will allow you to pass in your date string and a format string, and get a DateTime object in return.
I dealed with this issue today and upgrading my webdrivermanger solved it for me (My previous version was 3.0.0):

A field can be assigned to either the class or an instance of a class. By default fields are instance variables. By using static
the field becomes a class variable, thus there is one and only one clock
. If you make a changes in one place, it's visible everywhere. Instance varables are changed independently of one another.
There is also this way of specifying the viewmodel:
using Wpf = System.Windows;
public partial class App : Wpf.Application //your skeleton app already has this.
{
protected override void OnStartup( Wpf.StartupEventArgs e ) //you need to add this.
{
base.OnStartup( e );
MainWindow = new MainView();
MainWindow.DataContext = new MainViewModel( e.Args );
MainWindow.Show();
}
}
<Rant>
All of the solutions previously proposed require that MainViewModel
must have a parameterless constructor.
Microsoft is under the impression that systems can be built using parameterless constructors. If you are also under that impression, go ahead and use some of the other solutions.
For those that know that constructors must have parameters, and therefore the instantiation of objects cannot be left in the hands of magic frameworks, the proper way of specifying the viewmodel is the one I showed above.
</Rant>
Normally, that is not an error per se; it is a warning that the first file it found that matches the -lPI-Http
argument to the compiler/linker is not valid. The error occurs when no other library can be found with the right content.
So, you need to look to see whether /dvlpmnt/libPI-Http.a
is a library of 32-bit object files or of 64-bit object files - it will likely be 64-bit if you are compiling with the -m32
option. Then you need to establish whether there is an alternative libPI-Http.a
or libPI-Http.so
file somewhere else that is 32-bit. If so, ensure that the directory that contains it is listed in a -L/some/where
argument to the linker. If not, then you will need to obtain or build a 32-bit version of the library from somewhere.
To establish what is in that library, you may need to do:
mkdir junk
cd junk
ar x /dvlpmnt/libPI-Http.a
file *.o
cd ..
rm -fr junk
The 'file
' step tells you what type of object files are in the archive. The rest just makes sure you don't make a mess that can't be easily cleaned up.
\p{L}
matches a single code point in the category "letter".
\p{N}

Summary:
You opened up more than the allowed limit of connections to the database. You ran something like this: Connection conn = myconn.Open();
inside of a loop, and forgot to run conn.close();
. Just because your class is destroyed and garbage collected does not release the connection to the database. The quickest fix to this is to make sure you have the following code with whatever class that creates a connection:
protected void finalize() throws Throwable
{
try { your_connection.close(); }
catch (SQLException e) {
e.printStackTrace();
}
super.finalize();
}
Place that code in any class where you create a Connection. Then when your class is garbage collected, your connection will be released.
Run this SQL to see postgresql max connections allowed:
show max_connections;
The default is 100. PostgreSQL on good hardware can support a few hundred connections at a time. If you want to have thousands, you should consider using connection pooling software to reduce the connection overhead.
Take a look at exactly who/what/when/where is holding open your connections:
SELECT * FROM pg_stat_activity;
The number of connections currently used is:
SELECT COUNT(*) from pg_stat_activity;
Debugging strategy
You could give different usernames/passwords to the programs that might not be releasing the connections to find out which one it is, and then look in pg_stat_activity to find out which one is not cleaning up after itself.
Do a full exception stack trace when the connections could not be created and follow the code back up to where you create a new Connection
, make sure every code line where you create a connection ends with a connection.close();
How to set the max_connections higher:
max_connections in the postgresql.conf sets the maximum number of concurrent connections to the database server.
SHOW config_file;
/var/lib/pgsql/data/postgresql.conf
max_connections=100
.What's the maximum max_connections?
Use this query:
select min_val, max_val from pg_settings where name='max_connections';
I get the value 8388607
, in theory that's the most you are allowed to have, but then a runaway process can eat up thousands of connections, and surprise, your database is unresponsive until reboot. If you had a sensible max_connections like 100. The offending program would be denied a new connection.
Your code concatenates three strings, then converts the result to a number.
You need to convert each variable to a number by calling parseFloat()
around each one.
total = parseFloat(myInt1) + parseFloat(myInt2) + parseFloat(myInt3);
This function generates random string consisting of upper,lowercase letters, digits, pass the length seperator, no_of_blocks to specify your string format
eg: len_sep = 4, no_of_blocks = 4 will generate the following pattern,
F4nQ-Vh5z-JKEC-WhuS
Where, length seperator will add "-" after 4 characters
XXXX-
no of blocks will generate the following patten of characters as string
XXXX - XXXX - XXXX - XXXX
if a single random string is needed, just keep the no_of_blocks variable to be equal to 1 and len_sep to specify the length of the random string.
eg: len_sep = 10, no_of_blocks = 1, will generate the following pattern ie. random string of length 10,
F01xgCdoDU
import random as r
def generate_random_string(len_sep, no_of_blocks):
random_string = ''
random_str_seq = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
for i in range(0,len_sep*no_of_blocks):
if i % len_sep == 0 and i != 0:
random_string += '-'
random_string += str(random_str_seq[r.randint(0, len(random_str_seq) - 1)])
return random_string
session_start();
echo '<pre>';var_dump($_SESSION);echo '</pre>';
// or
echo '<pre>';print_r($_SESSION);echo '</pre>';
NOTE: session_start(); line is must then only you will able to print the value $_SESSION
I was the person who originated this convention back in 2006 and promoted it on the early jQuery mailing list, so let me share some of the history and motivation around it.
The accepted answer gives this example:
var $email = $("#email"); // refers to the jQuery object representation of the dom object
var email_field = $("#email").get(0); // refers to the dom object itself
But that doesn't really illustrate it well. Even without the $
, we would still have two different variable names here, email
and email_field
. That's plenty good right there. Why would we need to throw a $
into one of the names when we already have two different names?
Actually, I wouldn't have used email_field
here for two reasons: names_with_underscores
are not idiomatic JavaScript, and field
doesn't really make sense for a DOM element. But I did follow the same idea.
I tried a few different things, among them something very similar to the example:
var email = $("#email"), emailElement = $("#email")[0];
// Now email is a jQuery object and emailElement is the first/only DOM element in it
(Of course a jQuery object can have more than one DOM element, but the code I was working on had a lot of id
selectors, so in those cases there was a 1:1 correspondence.)
I had another case where a function received a DOM element as a parameter and also needed a jQuery object for it:
// email is a DOM element passed into this function
function doSomethingWithEmail( email ) {
var emailJQ = $(email);
// Now email is the DOM element and emailJQ is a jQuery object for it
}
Well that's a little confusing! In one of my bits of code, email
is the jQuery object and emailElement
is the DOM element, but in the other, email
is the DOM element and emailJQ
is the jQuery object.
There was no consistency and I kept mixing them up. Plus it was a bit of a nuisance to keep having to make up two different names for the same thing: one for the jQuery object and another for the matching DOM element. Besides email
, emailElement
, and emailJQ
, I kept trying other variations too.
Then I noticed a common pattern:
var email = $("#email");
var emailJQ = $(email);
Since JavaScript treats $
as simply another letter for names, and since I always got a jQuery object back from a $(whatever)
call, the pattern finally dawned on me. I could take a $(...)
call and just remove some characters, and it would come up with a pretty nice name:
$
("#email")$
(email)
Strikeout isn't perfect, but you may get the idea: with some characters deleted, both of those lines end up looking like:
$email
That's when I realized I didn't need to make up a convention like emailElement
or emailJQ
. There was already a nice convention staring at me: take some characters out of a $(whatever)
call and it turns into $whatever
.
var $email = $("#email"), email = $email[0];
// $email is the jQuery object and email is the DOM object
and:
// email is a DOM element passed into this function
function doSomethingWithEmail( email ) {
var $email = $(email);
// $email is the jQuery object and email is the DOM object
// Same names as in the code above. Yay!
}
So I didn't have to make up two different names all the time but could just use the same name with or without a $
prefix. And the $
prefix was a nice reminder that I was dealing with a jQuery object:
$('#email').click( ... );
or:
var $email = $('#email');
// Maybe do some other stuff with $email here
$email.click( ... );
If you need multiple branches on the same condition, use an if:
if (A == 6)
f(1, 2, 3);
else
f(4, 5, 6);
If you need multiple branches with different conditions, then if statement count would snowball, you'll want to use the ternary:
f( (A == 6)? 1: 4, (B == 6)? 2: 5, (C == 6)? 3: 6 );
Also, you can use the ternary operator in initialization.
const int i = (A == 6)? 1 : 4;
Doing that with if is very messy:
int i_temp;
if (A == 6)
i_temp = 1;
else
i_temp = 4;
const int i = i_temp;
You can't put the initialization inside the if/else, because it changes the scope. But references and const variables can only be bound at initialization.
You could build your form using FormBuilder as it let you more flexible way to configure form.
export class MyComp {
form: ControlGroup;
constructor(@Inject()fb: FormBuilder) {
this.form = fb.group({
foo: ['', MyValidators.regex(/^(?!\s|.*\s$).*$/)]
});
}
Then in your template :
<input type="text" ngControl="foo" />
<div *ngIf="!form.foo.valid">Please correct foo entry !</div>
You can also customize ng-invalid CSS class.
As there is actually no validators for regex, you have to write your own. It is a simple function that takes a control in input, and return null if valid or a StringMap if invalid.
export class MyValidators {
static regex(pattern: string): Function {
return (control: Control): {[key: string]: any} => {
return control.value.match(pattern) ? null : {pattern: true};
};
}
}
Hope that it help you.
The issue is that, even though you removed the files, they are still present in previous revisions. That's the whole point of git, is that even if you delete something, you can still get it back by accessing the history.
What you are looking to do is called rewriting history, and it involved the git filter-branch
command.
GitHub has a good explanation of the issue on their site. https://help.github.com/articles/remove-sensitive-data
To answer your question more directly, what you basically need to run is this command with unwanted_filename_or_folder
replaced accordingly:
git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch unwanted_filename_or_folder' --prune-empty
This will remove all references to the files from the active history of the repo.
Next step, to perform a GC cycle to force all references to the file to be expired and purged from the packfile. Nothing needs to be replaced in these commands.
git for-each-ref --format='delete %(refname)' refs/original | git update-ref --stdin
# or, for older git versions (e.g. 1.8.3.1) which don't support --stdin
# git update-ref $(git for-each-ref --format='delete %(refname)' refs/original)
git reflog expire --expire=now --all
git gc --aggressive --prune=now

This link explains where you're going wrong:
Place the definition of your constructors, destructors methods and whatnot in your header file, and that will correct the problem.
This offers another solution:
How can I avoid linker errors with my template functions?
However this requires you to anticipate how your template will be used and, as a general solution, is counter-intuitive. It does solve the corner case though where you develop a template to be used by some internal mechanism, and you want to police the manner in which it is used.

Being a void element, an <input>
element is considered empty by the HTML definition of "empty", since the content model of all void elements is always empty. So they will always match the :empty
pseudo-class, whether or not they have a value. This is also why their value is represented by an attribute in the start tag, rather than text content within start and end tags.
Also, from the Selectors spec:
The
:empty
pseudo-class represents an element that has no children at all. In terms of the document tree, only element nodes and content nodes (such as DOM text nodes, CDATA nodes, and entity references) whose data has a non-zero length must be considered as affecting emptiness;
Consequently, input:not(:empty)
will never match anything in a proper HTML document. (It would still work in a hypothetical XML document that defines an <input>
element that can accept text or child elements.)
I don't think you can style empty <input>
fields dynamically using just CSS (i.e. rules that apply whenever a field is empty, and don't once text is entered). You can select initially empty fields if they have an empty value
attribute (input[value=""]
) or lack the attribute altogether (input:not([value])
), but that's about it.
DateTime
is not standard nullable type. If you want assign null to DateTime
type of variable, you have to use DateTime?
type which supports null value.
If you only want test your variable to be set (e.g. variable holds other than default value), you can use keyword "default" like in following code:
if (dateTimeVariable == default(DateTime))
{
//do work for dateTimeVariable == null situation
}

URIs are a standard for identifying documents using a short string of numbers, letters, and symbols. They are defined by RFC 3986 - Uniform Resource Identifier (URI): Generic Syntax. URLs, URNs, and URCs are all types of URI.
Contains information about how to fetch a resource from its location. For example:
http://example.com/mypage.html
ftp://example.com/download.zip
mailto:[email protected]
file:///home/user/file.txt
tel:1-888-555-5555
http://example.com/resource?foo=bar#fragment
/other/link.html
(A relative URL, only useful in the context of another URL)URLs always start with a protocol (http
) and usually contain information such as the network host name (example.com
) and often a document path (/foo/mypage.html
). URLs may have query parameters and fragment identifiers.
Identifies a resource by a unique and persistent name, but doesn't necessarily tell you how to locate it on the internet. It usually starts with the prefix urn:
For example:
urn:isbn:0451450523
to identify a book by its ISBN number.urn:uuid:6e8bc430-9c3a-11d9-9669-0800200c9a66
a globally unique identifierurn:publishing:book
- An XML namespace that identifies the document as a type of book.URNs can identify ideas and concepts. They are not restricted to identifying documents. When a URN does represent a document, it can be translated into a URL by a "resolver". The document can then be downloaded from the URL.
Points to meta data about a document rather than to the document itself. An example of a URC is one that points to the HTML source code of a page like: view-source:http://example.com/
Rather than locating it on the internet, or naming it, data can be placed directly into a URI. An example would be data:,Hello%20World
.
The W3 spec for HTML says that the href
of an anchor tag can contain a URI, not just a URL. You should be able to put in a URN such as <a href="urn:isbn:0451450523">
. Your browser would then resolve that URN to a URL and download the book for you.
Not that I know of, but modern web browser do implement the data URI scheme.
No. Both relative and absolute URLs are URLs (and URIs.)
No. Both URLs with and without query parameters are URLs (and URIs.)
No. Both URLs with and without fragment identifiers are URLs (and URIs.)
No. URLs are defined to be a strict subset of URIs. If a parser allows a character in a URL but not in a URI, there is a bug in the parser. The specs go into great detail about which characters are allowed in which parts of URLs and URIs. Some characters may be allowed only in some parts of the URL, but characters alone are not a difference between URLs and URIs.
Yes. The W3C realized that there is a ton of confusion about this. They issued a URI clarification document that says that it is now OK to use the terms URL and URI interchangeably (to mean URI). It is no longer useful to strictly segment URIs into different types such as URL, URN, and URC.
The definition of URN is now looser than what I stated above. The latest RFC on URIs says that any URI can now be a URN (regardless of whether it starts with urn:
) as long as it has "the properties of a name." That is: It is globally unique and persistent even when the resource ceases to exist or becomes unavailable. An example: The URIs used in HTML doctypes such as http://www.w3.org/TR/html4/strict.dtd
. That URI would continue to name the HTML4 transitional doctype even if the page on the w3.org website were deleted.

Change It like this, It worked for me. Hope It helps. firs I did
$cfg['Servers'][$i]['verbose'] = 'mysql wampserver';
//$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'changed';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysql if your server does not have mysqli */
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = false;
Then I Changed Like this...
$cfg['Servers'][$i]['verbose'] = 'mysql wampserver';
//$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'root';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysql if your server does not have mysqli */
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = false;
To make @Mark Fisher's answer more clear, the inserted view being inflated should be a xml file under layout folder but without a layout (ViewGroup) like LinearLayout etc. inside. My example:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/i_am_id"
android:text="my name"
android:textSize="17sp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"/>
Then, the insertion point should be a layout like LinearLayout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/aaa"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/insert_point"
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
</RelativeLayout>
Then the code should be
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_shopping_cart);
LayoutInflater inflater = getLayoutInflater();
View view = inflater.inflate(R.layout.my_view, null);
ViewGroup main = (ViewGroup) findViewById(R.id.insert_point);
main.addView(view, 0);
}
The reason I post this very similar answer is that when I tried to implement Mark's solution, I got stuck on what xml file should I use for insert_point and the child view. I used layout in the child view firstly and it was totally not working, which took me several hours to figure out. So hope my exploration can save others' time.
You can do something like this in you getJsonResponse
function -
jData, err := json.Marshal(Data)
if err != nil {
// handle error
}
w.Header().Set("Content-Type", "application/json")
w.Write(jData)
You can simply use
pip install numpy
Or for python3, use
pip3 install numpy
assertEquals(Object, Object)
from JUnit4/JUnit 5 or assertThat(actual, is(expected));
from Hamcrest proposed in the other answers will work only as both equals()
and toString()
are overrided for the classes (and deeply) of the compared objects.
It matters because the equality test in the assertion relies on equals()
and the test failure message relies on toString()
of the compared objects.
For built-in classes such as String
, Integer
and so for ... no problem as these override both equals()
and toString()
. So it is perfectly valid to assert List<String>
or List<Integer>
with assertEquals(Object,Object)
.
And about this matter : you have to override equals()
in a class because it makes sense in terms of object equality, not only to make assertions easier in a test with JUnit.
To make assertions easier you have other ways.
As a good practice I favor assertion/matcher libraries.
Here is a AssertJ solution.
org.assertj.core.api.ListAssert.containsExactly()
is what you need : it verifies that the actual group contains exactly the given values and nothing else, in order as stated in the javadoc.
Suppose a Foo
class where you add elements and where you can get that.
A unit test of Foo
that asserts that the two lists have the same content could look like :
import org.assertj.core.api.Assertions;
import org.junit.jupiter.api.Test;
@Test
void add() throws Exception {
Foo foo = new Foo();
foo.add("One", "Two", "Three");
Assertions.assertThat(foo.getElements())
.containsExactly("One", "Two", "Three");
}
A AssertJ good point is that declaring a List
as expected is needless : it makes the assertion straighter and the code more readable :
Assertions.assertThat(foo.getElements())
.containsExactly("One", "Two", "Three");
But Assertion/matcher libraries are a must because these will really further.
Suppose now that Foo
doesn't store String
s but Bar
s instances.
That is a very common need.
With AssertJ the assertion is still simple to write. Better you can assert that the list content are equal even if the class of the elements doesn't override equals()/hashCode()
while JUnit way requires that :
import org.assertj.core.api.Assertions;
import static org.assertj.core.groups.Tuple.tuple;
import org.junit.jupiter.api.Test;
@Test
void add() throws Exception {
Foo foo = new Foo();
foo.add(new Bar(1, "One"), new Bar(2, "Two"), new Bar(3, "Three"));
Assertions.assertThat(foo.getElements())
.extracting(Bar::getId, Bar::getName)
.containsExactly(tuple(1, "One"),
tuple(2, "Two"),
tuple(3, "Three"));
}
I had a similar problem and it was related to the version. In a python terminal check:
>> import xlrd
>> xlrd.__VERSION__
If you have '0.9.0' you can open almost all files. If you have '0.6.0' which was what I found on Ubuntu, you may have problems with newest Excel files. You can download the latest version of xlrd using the Distutils standard.
for Android Studio 3.0.1, you can config GitHub path for following path:
$("input[type=text][value=]")
After trying a lots of version I found this the most logical.
Note that text
is case-sensitive.
You could query the dataset and then loop the selected rows to set them as delete.
var rows = dt.Select("col1 > 5");
foreach (var row in rows)
row.Delete();
... and you could also create some extension methods to make it easier ...
myTable.Delete("col1 > 5");
public static DataTable Delete(this DataTable table, string filter)
{
table.Select(filter).Delete();
return table;
}
public static void Delete(this IEnumerable<DataRow> rows)
{
foreach (var row in rows)
row.Delete();
}
You can add destroy:true
to the configuration to make sure data table already present is removed before being reinitialized.
$('#example').dataTable({
destroy: true,
...
});
A chain:
Especially the roller chain:
Each element of the chain is connected to its successor and predecessor.
To complete the current answers and as the question is not language specific, some C-project use the prefix m_
to define global variables that are specific to a file - and g_
for global variables that have a scoped larger than the file they are defined.
In this case global variables defined with prefix m_
should be defined as static
.
See EDK2 (a UEFI Open-Source implementation) coding convention for an example of project using this convention.
datediff(to_date(String timestamp), to_date(String timestamp))
For example:
SELECT datediff(to_date('2019-08-03'), to_date('2019-08-01')) <= 2;

(Firstly read the other answers which has explained the for
in the <label></label>
tags.
Well, both the tops answers are correct, but for my challenge, it was when you have several radio boxes, you should select for them a common name like name="r1"
but with different ids id="r1_1" ... id="r1_2"
So this way the answer is more clear and removes the conflicts between name and ids as well.
You need different ids for different options of the radio box.
<input type="radio" name="r1" id="r1_1" />_x000D_
_x000D_
<label for="r1_1">button text one</label>_x000D_
<br/>_x000D_
<input type="radio" name="r1" id="r1_2" />_x000D_
_x000D_
<label for="r1_2">button text two</label>_x000D_
<br/>_x000D_
<input type="radio" name="r1" id="r1_3" />_x000D_
_x000D_
<label for="r1_3">button text three</label>

Facebook uses Bit.ly's services to shorten links from their site. While pages that have a username turns into "fb.me/<username>
", other links associated with Facebook turns into "on.fb.me/*****
". To you use the on.fb.me service, just use your Bit.ly account. Note that if you change the default link shortener on your Bit.ly account to j.mp from bit.ly this service won't work.
Thanks to Giles Gardam for his answer, but it addresses only longitude and not latitude. A complete solution should calculate the zoom level needed for latitude and the zoom level needed for longitude, and then take the smaller (further out) of the two.
Here is a function that uses both latitude and longitude:
function getBoundsZoomLevel(bounds, mapDim) {
var WORLD_DIM = { height: 256, width: 256 };
var ZOOM_MAX = 21;
function latRad(lat) {
var sin = Math.sin(lat * Math.PI / 180);
var radX2 = Math.log((1 + sin) / (1 - sin)) / 2;
return Math.max(Math.min(radX2, Math.PI), -Math.PI) / 2;
}
function zoom(mapPx, worldPx, fraction) {
return Math.floor(Math.log(mapPx / worldPx / fraction) / Math.LN2);
}
var ne = bounds.getNorthEast();
var sw = bounds.getSouthWest();
var latFraction = (latRad(ne.lat()) - latRad(sw.lat())) / Math.PI;
var lngDiff = ne.lng() - sw.lng();
var lngFraction = ((lngDiff < 0) ? (lngDiff + 360) : lngDiff) / 360;
var latZoom = zoom(mapDim.height, WORLD_DIM.height, latFraction);
var lngZoom = zoom(mapDim.width, WORLD_DIM.width, lngFraction);
return Math.min(latZoom, lngZoom, ZOOM_MAX);
}
Parameters:
The "bounds" parameter value should be a google.maps.LatLngBounds
object.
The "mapDim" parameter value should be an object with "height" and "width" properties that represent the height and width of the DOM element that displays the map. You may want to decrease these values if you want to ensure padding. That is, you may not want map markers within the bounds to be too close to the edge of the map.
If you are using the jQuery library, the mapDim
value can be obtained as follows:
var $mapDiv = $('#mapElementId');
var mapDim = { height: $mapDiv.height(), width: $mapDiv.width() };
If you are using the Prototype library, the mapDim value can be obtained as follows:
var mapDim = $('mapElementId').getDimensions();
Return Value:
The return value is the maximum zoom level that will still display the entire bounds. This value will be between 0
and the maximum zoom level, inclusive.
The maximum zoom level is 21. (I believe it was only 19 for Google Maps API v2.)
Explanation:
Google Maps uses a Mercator projection. In a Mercator projection the lines of longitude are equally spaced, but the lines of latitude are not. The distance between lines of latitude increase as they go from the equator to the poles. In fact the distance tends towards infinity as it reaches the poles. A Google Maps map, however, does not show latitudes above approximately 85 degrees North or below approximately -85 degrees South. (reference) (I calculate the actual cutoff at +/-85.05112877980658 degrees.)
This makes the calculation of the fractions for the bounds more complicated for latitude than for longitude. I used a formula from Wikipedia to calculate the latitude fraction. I am assuming this matches the projection used by Google Maps. After all, the Google Maps documentation page I link to above contains a link to the same Wikipedia page.
Other Notes:
I wrote small library ssl-utils-android to trust particular certificate on Android.
You can simply load any certificate by giving the filename from assets directory.
Usage:
OkHttpClient client = new OkHttpClient();
SSLContext sslContext = SslUtils.getSslContextForCertificateFile(context, "BPClass2RootCA-sha2.cer");
client.setSslSocketFactory(sslContext.getSocketFactory());
They are not equivalent. The first will execute the block following the if
statement if myVar
is truthy (i.e. evaluates to true
in a conditional), while the second will execute the block if myVar
is any value other than null
.
The only values that are not truthy in JavaScript are the following (a.k.a. falsy values):
null
undefined
0
""
(the empty string)false
NaN
import pandas as pd
import os
files = os.listdir('path/to/files/directory/')
desiredFile = files[i]
filePath = 'path/to/files/directory/%s'
Ofile = filePath % desiredFile
xls_import = pd.read_csv(Ofile)
Now you can use the power of pandas DataFrames!
You can also create a small VBScript script:
Set env = CreateObject("WScript.Shell").Environment("System")
If env(WScript.Arguments(0)) <> vbNullString Then env.Remove WScript.Arguments(0)
Then call it like %windir%\System32\cscript.exe //Nologo "script_name.vbs" FOOBAR
.
The disadvantage is you need an extra script, but it does not require a reboot.
I suggest Junidecode . It will handle not only 'L' and 'Ø', but it also works well for transcribing from other alphabets, such as Chinese, into Latin alphabet.
Just because it happened to me and can be useful. If you do this
try {
...
} catch (Exception e) {
log.error( "failed! {}", e );
}
you will get the header of the exception and not the whole stacktrace. Because the logger will think that you are passing a String.
Do it without {}
as skaffman said
You could also turn on autoextend for the whole database using this command:
ALTER DATABASE DATAFILE 'C:\ORACLEXE\APP\ORACLE\ORADATA\XE\SYSTEM.DBF'
AUTOEXTEND ON NEXT 1M MAXSIZE 1024M;
Just change the filepath to point to your system.dbf file.

Regardless of your situation, heres a working demo that creates markers on the map based on an array of addresses.
Javascript code embedded aswell:
$(document).ready(function () {
var map;
var elevator;
var myOptions = {
zoom: 1,
center: new google.maps.LatLng(0, 0),
mapTypeId: 'terrain'
};
map = new google.maps.Map($('#map_canvas')[0], myOptions);
var addresses = ['Norway', 'Africa', 'Asia','North America','South America'];
for (var x = 0; x < addresses.length; x++) {
$.getJSON('http://maps.googleapis.com/maps/api/geocode/json?address='+addresses[x]+'&sensor=false', null, function (data) {
var p = data.results[0].geometry.location
var latlng = new google.maps.LatLng(p.lat, p.lng);
new google.maps.Marker({
position: latlng,
map: map
});
});
}
});
Sending raw POST requests can be sometimes more convenient. Below you can see post.js original example from PhantomJS
// Example using HTTP POST operation
var page = require('webpage').create(),
server = 'http://posttestserver.com/post.php?dump',
data = 'universe=expanding&answer=42';
page.open(server, 'post', data, function (status) {
if (status !== 'success') {
console.log('Unable to post!');
} else {
console.log(page.content);
}
phantom.exit();
});

The original question specifically asked for Unix but multiple answers have touched on Windows, and as a result there is misleading information on windows. The default timer resolution on windows is 15.6ms you can verify here.
Using a slightly modified script from cod3monk3y I can show that windows timer resolution is ~15milliseconds by default. I'm using a tool available here to modify the resolution.
Script:
import time
# measure the smallest time delta by spinning until the time changes
def measure():
t0 = time.time()
t1 = t0
while t1 == t0:
t1 = time.time()
return t1-t0
samples = [measure() for i in range(30)]
for s in samples:
print(f'time delta: {s:.4f} seconds')
These results were gathered on windows 10 pro 64-bit running python 3.7 64-bit.
Use the csv
module:
import csv
with open("test.csv", "r") as f:
reader = csv.reader(f, delimiter="\t")
for i, line in enumerate(reader):
print 'line[{}] = {}'.format(i, line)
Output:
line[0] = ['Year:', 'Dec:', 'Jan:']
line[1] = ['1', '50', '60']
line[2] = ['2', '25', '50']
line[3] = ['3', '30', '30']
line[4] = ['4', '40', '20']
line[5] = ['5', '10', '10']
Your Fragment can subclass ListFragment.
And onCreateView() from ListFragment
will return a ListView
you can then populate.
You can test it by using this snipped code:
private static void Main(string[] args)
{
int threadCount = 0;
try
{
for (int i = 0; i < int.MaxValue; i ++)
{
new Thread(() => Thread.Sleep(Timeout.Infinite)).Start();
threadCount ++;
}
}
catch
{
Console.WriteLine(threadCount);
Console.ReadKey(true);
}
}

That is not pass-by-reference, that is pass-by-value as others stated.
The C language is pass-by-value without exception. Passing a pointer as a parameter does not mean pass-by-reference.
The rule is the following:
A function is not able to change the actual parameters value.
Let's try to see the differences between scalar and pointer parameters of a function.
This short program shows pass-by-value using a scalar variable. param
is called the formal parameter and variable
at function invocation is called actual parameter. Note incrementing param
in the function does not change variable
.
#include <stdio.h>
void function(int param) {
printf("I've received value %d\n", param);
param++;
}
int main(void) {
int variable = 111;
function(variable);
printf("variable %d\m", variable);
return 0;
}
The result is
I've received value 111
variable=111
We change the piece of code slightly. param
is a pointer now.
#include <stdio.h>
void function2(int *param) {
printf("I've received value %d\n", *param);
(*param)++;
}
int main(void) {
int variable = 111;
function2(&variable);
printf("variable %d\n", variable);
return 0;
}
The result is
I've received value 111
variable=112
That makes you believe that the parameter was passed by reference. It was not. It was passed by value, the param value being an address. The int type value was incremented, and that is the side effect that make us think that it was a pass-by-reference function call.
How can we show/prove that fact? Well, maybe we can try the first example of Scalar variables, but instead of scalar we use addresses (pointers). Let's see if that can help.
#include <stdio.h>
void function2(int *param) {
printf("param's address %d\n", param);
param = NULL;
}
int main(void) {
int variable = 111;
int *ptr = &variable;
function2(ptr);
printf("ptr's address %d\n", ptr);
return 0;
}
The result will be that the two addresses are equal (don't worry about the exact value).
Example result:
param's address -1846583468
ptr's address -1846583468
In my opinion this proves clearly that pointers are passed-by-value. Otherwise ptr
would be NULL
after function invocation.

In JUnit 4, another option for you may be to create an annotation to denote that the test needs to meet your custom criteria, then extend the default runner with your own and using reflection, base your decision on the custom criteria. It may look something like this:

Assuming maven project:
Properties file should be in src/main/resources/database
folder
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=your db url
jdbc.username=your Username
jdbc.password=Your password
hibernate.max_fetch_depth = 3
hibernate.jdbc.fetch_size = 50
hibernate.jdbc.batch_size = 10
hibernate.show_sql = true
ServiceMarker and RepositoryMarker are just empty interfaces in your service or repository impl package.
Let's say you have package name a.b.c.service.impl
. MyServiceImpl is in this package and so is ServiceMarker.
public interface ServiceMarker {
}
Same for repository marker. Let's say you have a.b.c.repository.impl
or a.b.c.dao.impl
package name. Then MyDaoImpl is in this this package and also Repositorymarker
public interface RepositoryMarker {
}
//dummy class and dummy query
@Entity
@NamedQueries({
@NamedQuery(name="Student.findByKey", query="select s from Student s where s.fromDate=:fromDate" and s.toDate = :toDate)
})
public class Student implements Serializable {
private LocalDateTime fromDate;
private LocalDateTime toDate;
//getters setters
}
@Converter(autoApply = true)
public class LocalDateTimeConverter implements AttributeConverter<LocalDateTime, Timestamp> {
@Override
public Timestamp convertToDatabaseColumn(LocalDateTime dateTime) {
if (dateTime == null) {
return null;
}
return Timestamp.valueOf(dateTime);
}
@Override

return timestamp.toLocalDateTime();

To convert the int 'x'
int x = 3;
One way, by manipulation on the int :
string s = Convert.ToString(x, 2); //Convert to binary in a string
int[] bits= s.PadLeft(8, '0') // Add 0's from left
.Select(c => int.Parse(c.ToString())) // convert each char to int
.ToArray(); // Convert IEnumerable from select to Array
Alternatively, by using the BitArray class-
BitArray b = new BitArray(new byte[] { x });
int[] bits = b.Cast<bool>().Select(bit => bit ? 1 : 0).ToArray();
This should get you there every single time.

Have in mind that clone()
doesn't work out of the box. You will have to implement Cloneable
and override the clone()
method making in public
.
There are a few alternatives, which are preferable (since the clone()
method has lots of design issues, as stated in other answers), and the copy-constructor would require manual work:
BeanUtils.cloneBean(original)
creates a shallow clone, like the one created by Object.clone()
. (this class is from commons-beanutils)
SerializationUtils.clone(original)
creates a deep clone. (i.e. the whole properties graph is cloned, not only the first level) (from commons-lang), but all classes must implement Serializable
Java Deep Cloning Library offers deep cloning without the need to implement Serializable
My answer is similar to Paolo's answer.
I think module requests
is much better. It's based on urllib3
.
You can try this:
>>> from requests.utils import quote
>>> quote('/test')
'/test'
>>> quote('/test', safe='')
'%2Ftest'
What Works:
string relativePath = "..\\bling.txt";
string baseDirectory = "C:\\blah\\";
string absolutePath = Path.GetFullPath(baseDirectory + relativePath);
(result: absolutePath="C:\bling.txt")
What doesn't work
string relativePath = "..\\bling.txt";
Uri baseAbsoluteUri = new Uri("C:\\blah\\");
string absolutePath = new Uri(baseAbsoluteUri, relativePath).AbsolutePath;
(result: absolutePath="C:/blah/bling.txt")
let's me give a more detail example:
import numpy as np
import matplotlib.pyplot as plt
def draw_result(lst_iter, lst_loss, lst_acc, title):
plt.plot(lst_iter, lst_loss, '-b', label='loss')
plt.plot(lst_iter, lst_acc, '-r', label='accuracy')
plt.xlabel("n iteration")
plt.legend(loc='upper left')
plt.title(title)
plt.savefig(title+".png") # should before plt.show method
plt.show()
def test_draw():
lst_iter = range(100)
lst_loss = [0.01 * i + 0.01 * i ** 2 for i in xrange(100)]
# lst_loss = np.random.randn(1, 100).reshape((100, ))
lst_acc = [0.01 * i - 0.01 * i ** 2 for i in xrange(100)]
# lst_acc = np.random.randn(1, 100).reshape((100, ))
draw_result(lst_iter, lst_loss, lst_acc, "sgd_method")
if __name__ == '__main__':
test_draw()
I know this is an old question but I came across it while trying to solve this same issue. I thought it'd be worth sharing this solution I hadn't found anywhere else.
Basically the solution is to use CSS to hide the <input>
element and style a <label>
around it to look like a button. Click the 'Run code snippet' button to see the results.
I had used a JavaScript solution before that worked fine too but it is nice to solve a 'presentation' issue with just CSS.
label.cameraButton {_x000D_
display: inline-block;_x000D_
margin: 1em 0;_x000D_
_x000D_
/* Styles to make it look like a button */_x000D_
padding: 0.5em;_x000D_
border: 2px solid #666;_x000D_
border-color: #EEE #CCC #CCC #EEE;_x000D_
background-color: #DDD;_x000D_
}_x000D_
_x000D_
/* Look like a clicked/depressed button */_x000D_
label.cameraButton:active {_x000D_
border-color: #CCC #EEE #EEE #CCC;_x000D_
}_x000D_
_x000D_
/* This is the part that actually hides the 'Choose file' text box for camera inputs */_x000D_
label.cameraButton input[accept*="camera"] {_x000D_
display: none;_x000D_
}
_x000D_

You have to call
setPadding(int left, int top, int right, int bottom)
like so:
your_view.setPadding(0,16,0,0)
What you are trying to use is only the getter.
Android studio shows what padding...()
actually means in java:
padding example
The image shows it only calls getPadding...()
If you want to add a margin to your TextView you will have to LayoutParams:
val params = LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT)
params.setMargins(int left, int top, int right, int bottom)
your_view.layoutParams = params
Try SELECT CAST(field1 AS DECIMAL(10,2)) field1
and replace 10,2
with whatever precision you need.
Here is a workable answer.

As Already mentioned we have two ways!
And it's done interactively! And take effect immediately!
CTRL + A followed by : And we type scrollback 1000000
And hit ENTER
You detach from the screen and come back! It will be always the same.
You open another new screen! And the value is reset again to default! So it's not a global setting!
Which is done by adding defscrollback 1000000
to .screenrc
(in home)
defscrollback
and not scrollback
(def stand for default)
What you need to know is if the file is not created ! You create it !
> cd ~ && vim .screenrc
And you add defscrollback 1000000
to it!
Or in one command
> echo "defscrollback 1000000" >> .screenrc
(if not created already)
When you add the default to .screenrc
! The already running screen at re-attach will not take effect! The .screenrc
run at the screen creation! And it make sense! Just as with a normal console and shell launch!
And all the new created screens will have the set value!
To check type CTRL + A followed by i
And The result will be as
Importantly the buffer size is the number after the + sign
(in the illustration i set it to 1 000 000)
Note too that when you change it interactively! The effect is immediate and take over the default value!
CTRL+ A followed by ESC (to enter the copy mode).
Then navigate with Up,Down or PgUp PgDown
And ESC again to quit that mode.
(Extra info: to copy hit ENTER to start selecting! Then ENTER again to copy! Simple and cool)
Now the buffer is bigger!
And that's sum it up for the important details!
Regularization can help. For a classifier, there is a good case for activity regularization, whether it is binary or a multi-class classifier. For a regressor, kernel regularization might be more appropriate.
I think I've figured this one out. I imported the new WWDR Certificate that expires in 2023, but I was still getting problems building and my developer certificates were still showing the invalid issuer error.
After deleting the expired certificate from the login and System keychains, I was able to build for Distribution again.
Use the content property and style that content. Content behavior is then adjusted using pseudo elements. Pseudo elements ::before and ::after both work in Mac Safari 10.0.3.
Here element br content is used as the element anchor for element br::after content. Element br is where br spacing can be styled. br::after is the place where br::after content can be displayed and styled. Looks pretty, but not a 2px <br>.
br { content: ""; display: block; margin: 1rem 0; }
br::after { content: "› "; /* content: " " space ignored */; float: left; margin-right: 0.5rem; }
The br element line-height property is ignored. If negative values are applied to either or both selectors to give vertical 'lift' to br tags in display, then correct vertical spacing occurs, but display incrementally indents display content following each br tag. The indent is exactly equal to the amount that lift varies from actual typographic line-height. If you guess the right lift, there is no indent but a single pile-up line exactly equal to raw glyph height, jammed between previous and following lines.
Further, a trailing br tag will cause the following html display tag to inherit the br:after content styling. Also, pseudo elements cause <br> <br> to be interpreted as a single <br>. While pseudo-class br:active causes each <br> to be interpreted separately. Finally, using br:active ignores pseudo element br:after and all br:active styling. So, all that's required is this:
br:active { }
which is no help for creating a 2px high <br> display. And here the pseudo class :active is ignored!
br:active { content: ""; display: block; margin: 1.25em 0; }
br { content: ""; display: block; margin: 1rem; }
br::after { content: "› "; /* content: " " space ignored */; float: left; margin-right: 0.5rem; }
This is a partial solution only. Pseudo class and pseudo element may provide solution, if tweaked. This may be part of CSS solution. (I only have Safari, try it in other browsers.)
Use the join
method of the empty string to join all of the strings together with the empty string in between, like so:
>>> a = ['a', 'b', 'c', 'd']
>>> ''.join(a)
'abcd'
$_SERVER["PHP_SELF"];
will give you the current filename and its path, but basename(__FILE__)
should give you the filename that it is called from.
So
if(basename(__FILE__) == 'file_name.php') {
//Hide
} else {
//show
}
should do it.
The stack already exists, so you can assume that when writing your code. The stack contains the return addresses of the functions, the local variables and the variables which are passed between functions. There are also stack registers such as BP, SP (Stack Pointer) built-in that you can use, hence the built-in commands you have mentioned. If the stack wasn't already implemented, functions couldn't run, and code flow couldn't work.
Yes, you would use the header function.
/* Redirect browser */
header("Location: http://www.yourwebsite.com/user.php");
exit();
It is a good practice to call exit()
right after it so that code below it does not get executed.
Also, from the documentation:
Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include(), or require(), functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.
This means you should not echo anything right before the header()
function, as doing so will more than likely throw an error. Also, you will need to verify that this code gets run before any other output as well.
Android Support V7 GridLayout library makes excess space distribution easy by accommodating the principle of weight. To make a column stretch, make sure the components inside it define a weight or a gravity. To prevent a column from stretching, ensure that one of the components in the column does not define a weight or a gravity. Remember to add dependency for this library. Add com.android.support:gridlayout-v7:25.0.1 in build.gradle.

This is similar to one of the answers but in different way :
scala> val x = List(1,2,3)
x: List[Int] = List(1, 2, 3)
scala> val y = x ::: 4 :: Nil
y: List[Int] = List(1, 2, 3, 4)
Usually that problem is that in the last iteration you have an empty object or undefine object. use console.log() inside you cicle to check that this doent happend.
Sometimes a prototype in some place add an extra element.
If you decide to use Underscore.js you better do
_.values(ahash)[0]
to get value, or
_.keys(ahash)[0]
to get key.
This works.

By using exploits or on badly configured servers it could be possible to download your PHP source. You could however either obfuscate and/or encrypt your code (using Zend Guard, Ioncube or a similar app) if you want to make sure your source will not be readable (to be accurate, obfuscation by itself could be reversed given enough time/resources, but I haven't found an IonCube or Zend Guard decryptor yet...).

I know this post is closed but I think my way could help some people. So there it is :
My dataset is very similar but is a bit more complex. It has numbers, alphanumeric data :
1
2
Chair
3
0
4
5
-
Table
10
13
19
Windows
99
102
Dog
I would like to have the '-' symbol at first, then the numbers, then the text.
So I go like this :
SELECT name, (name = '-') boolDash, (name = '0') boolZero, (name+0 > 0) boolNum
FROM table
ORDER BY boolDash DESC, boolZero DESC, boolNum DESC, (name+0), name
The result should be something :
-
0
1
2
3
4
5
10
13
99
102
Chair
Dog
Table
Windows
The whole idea is doing some simple check into the SELECT and sorting with the result.
More information about how you'll be working with your data before transferring it would help a ton. The json module provides dump(s) and load(s) methods that'll help if you're using 2.6 or newer: http://docs.python.org/library/json.html.
-- EDITED --
Without knowing which libraries you're using I can't tell you for sure if you'll find a method like that. Normally, I'll process query results like this (examples with kinterbasdb because it's what we're currently working with):
qry = "Select Id, Name, Artist, Album From MP3s Order By Name, Artist"
# Assumes conn is a database connection.
cursor = conn.cursor()
cursor.execute(qry)
rows = [x for x in cursor]
cols = [x[0] for x in cursor.description]
songs = []
for row in rows:
song = {}
for prop, val in zip(cols, row):
song[prop] = val
songs.append(song)
# Create a string representation of your array of songs.
songsJSON = json.dumps(songs)
There are undoubtedly better experts out there who'll have list comprehensions to eliminate the need for written out loops, but this works and should be something you could adapt to whatever library you're retrieving records with.
It's your "fault" in that that's how Or
is defined, so it's the behaviour you should expect:
In a Boolean comparison, the Or operator always evaluates both expressions, which could include making procedure calls. The OrElse Operator (Visual Basic) performs short-circuiting, which means that if expression1 is True, then expression2 is not evaluated.
But you don't have to endure it. You can use OrElse
to get short-circuiting behaviour.
So you probably want:
If (example Is Nothing OrElse Not example.Item = compare.Item) Then
'Proceed
End If
I can't say it reads terribly nicely, but it should work...
If you need to join xpath-selected text nodes but can not use string-join
(when you are stuck with XSL 1.0) this might help:
<xsl:variable name="x">
<xsl:apply-templates select="..." mode="string-join-mode"/>
</xsl:variable>
joined and normalized: <xsl:value-of select="normalize-space($x)"/>
<xsl:template match="*" mode="string-join-mode">
<xsl:apply-templates mode="string-join-mode"/>
</xsl:template>
<xsl:template match="text()" mode="string-join-mode">
<xsl:value-of select="."/>
</xsl:template>
The trick I've seen used is to make a custom transparent button the size of the whole view and then in its click method, have the text field resign first responder. So the user can click anywhere outside of the field to dismiss the keypad.
Menu file:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/play"
android:titleCondensed="Speak"
android:showAsAction="always"
android:title="Speak"
android:icon="@drawable/ic_play">
</item>
<item
android:id="@+id/pause"
android:titleCondensed="Stop"
android:title="Stop"
android:showAsAction="always"
android:icon="@drawable/ic_pause">
</item>
</menu>
Activity code:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.speak_menu_history, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.play:
Toast.makeText(getApplicationContext(), "speaking....", Toast.LENGTH_LONG).show();
return false;
case R.id.pause:
Toast.makeText(getApplicationContext(), "stopping....", Toast.LENGTH_LONG).show();
return false;
default:
break;
}
return false;
}
Fragment code:
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.play:
text = page.getText().toString();
speakOut(text);
// Do Activity menu item stuff here
return true;
case R.id.pause:
speakOf();
// Not implemented here
return true;
default:
break;
}
return false;
}
If you are talking about two kinds of enitities, say teachers and students, you would create two tables for each and a third one to store the relationship. This third table can have two columns, say teacherID and StudentId. If this is not what you are looking for, please elaborate your question.
Adding to Sani's and blak3r's answers, I've added the following to the startup code for my application, but in VB:
'** Overriding the certificate validation check.
Net.ServicePointManager.ServerCertificateValidationCallback = Function(sender, certificate, chain, sslPolicyErrors) True
Seems to do the trick.
