Given a choice between the solution advocated by IServiceOriented.com and the solution advocated by David Barret's blog, I prefer the simplicity offered by overriding the client's Dispose() method. This allows me to continue to use the using() statement as one would expect with a disposable object. However, as @Brian pointed out, this solution contains a race condition in that the State might not be faulted when it is checked but could be by the time Close() is called, in which case the CommunicationException still occurs.
So, to get around this, I've employed a solution that mixes the best of both worlds.
void IDisposable.Dispose()
{
bool success = false;
try
{
if (State != CommunicationState.Faulted)
{
Close();
success = true;
}
}
finally
{
if (!success)
Abort();
}
}
You just need to add this line to the window there:
exec (your stored proc name) (and possibly add parameters)
What is your stored proc called, and what parameters does it expect?
Note: all the examples here are using the OpenCV 2.X API.
In OpenCV 3.X, you need to use:
Ptr<SimpleBlobDetector> d = SimpleBlobDetector::create(params);

If you are running your project in Docker, you should do the echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf
and all other commands in the host machine, since the container will inherit that setting automatically (and doing it directly inside it will not work).
It also works without jQuery if you do the following changes:
Add type="button"
to the edit button in order not to trigger submission of the form.
Change the name of your function from change()
to anything else.
Don't use hidden="hidden"
, use CSS instead: style="display: none;"
.
The following code works for me:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="STYLESHEET" type="text/css" href="dba_style/buttons.css" />
<title>Untitled Document</title>
</head>
<script type="text/javascript">
function do_change(){
document.getElementById("save").style.display = "block";
document.getElementById("change").style.display = "block";
document.getElementById("cancel").style.display = "block";
}
</script>
<body>
<form name="form1" method="post" action="">
<div class="buttons">
<button type="button" class="regular" name="edit" id="edit" onclick="do_change(); return false;">
<img src="dba_images/textfield_key.png" alt=""/>
Edit
</button>
<button type="submit" class="positive" name="save" id="save" style="display:none;">
<img src="dba_images/apply2.png" alt=""/>
Save
</button>
<button class="regular" name="change" id="change" style="display:none;">
<img src="dba_images/textfield_key.png" alt=""/>
change

<button class="negative" name="cancel" id="cancel" style="display:none;">
<img src="dba_images/cross.png" alt=""/>
Cancel
</button>
</div>
</form>
</body>
</html>
You need to set the text after the replace call:
$('.element span').each(function() {_x000D_
console.log($(this).text());_x000D_
var text = $(this).text().replace('N/A, ', '');_x000D_
$(this).text(text);_x000D_
});
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div class="element">_x000D_
<span>N/A, Category</span>_x000D_
</div>
_x000D_
Here's another cool way you can do it (hat tip @Felix King):
$(".element span").text(function(index, text) {
return text.replace("N/A, ", "");
});
Java is nothing like C++, contrary to hype. The Java hype machine would like you to believe that because Java has C++ like syntax, that the languages are similar. Nothing can be further from the truth. This misinformation is part of the reason why Java programmers go to C++ and use Java-like syntax without understanding the implications of their code.
But I can't figure out why should we do it this way. I would assume it has to do with efficiency and speed since we get direct access to the memory address. Am I right?
To the contrary, actually. The heap is much slower than the stack, because the stack is very simple compared to the heap. Automatic storage variables (aka stack variables) have their destructors called once they go out of scope. For example:
{
std::string s;
}
// s is destroyed here
On the other hand, if you use a pointer dynamically allocated, its destructor must be called manually. delete
calls this destructor for you.
{
std::string* s = new std::string;
}
delete s; // destructor called
This has nothing to do with the new
syntax prevalent in C# and Java. They are used for completely different purposes.
1. You don't have to know the size of the array in advance
One of the first problems many C++ programmers run into is that when they are accepting arbitrary input from users, you can only allocate a fixed size for a stack variable. You cannot change the size of arrays either. For example:
char buffer[100];
std::cin >> buffer;
// bad input = buffer overflow
Of course, if you used an std::string
instead, std::string
internally resizes itself so that shouldn't be a problem. But essentially the solution to this problem is dynamic allocation. You can allocate dynamic memory based on the input of the user, for example:
int * pointer;
std::cout << "How many items do you need?";
std::cin >> n;
pointer = new int[n];
Side note: One mistake many beginners make is the usage of variable length arrays. This is a GNU extension and also one in Clang because they mirror many of GCC's extensions. So the following
int arr[n]
should not be relied on.
Because the heap is much bigger than the stack, one can arbitrarily allocate/reallocate as much memory as he/she needs, whereas the stack has a limitation.
2. Arrays are not pointers
How is this a benefit you ask? The answer will become clear once you understand the confusion/myth behind arrays and pointers. It is commonly assumed that they are the same, but they are not. This myth comes from the fact that pointers can be subscripted just like arrays and because of arrays decay to pointers at the top level in a function declaration. However, once an array decays to a pointer, the pointer loses its sizeof
information. So sizeof(pointer)
will give the size of the pointer in bytes, which is usually 8 bytes on a 64-bit system.
You cannot assign to arrays, only initialize them. For example:
int arr[5] = {1, 2, 3, 4, 5}; // initialization
int arr[] = {1, 2, 3, 4, 5}; // The standard dictates that the size of the array
// be given by the amount of members in the initializer
arr = { 1, 2, 3, 4, 5 }; // ERROR
On the other hand, you can do whatever you want with pointers. Unfortunately, because the distinction between pointers and arrays are hand-waved in Java and C#, beginners don't understand the difference.
3. Polymorphism
Java and C# have facilities that allow you to treat objects as another, for example using the as
keyword. So if somebody wanted to treat an Entity
object as a Player
object, one could do Player player = Entity as Player;
This is very useful if you intend to call functions on a homogeneous container that should only apply to a specific type. The functionality can be achieved in a similar fashion below:
std::vector<Base*> vector;
vector.push_back(&square);
vector.push_back(&triangle);
for (auto& e : vector)
{
auto test = dynamic_cast<Triangle*>(e); // I only care about triangles
if (!test) // not a triangle
e.GenericFunction();
else
e.TriangleOnlyMagic();
}
So say if only Triangles had a Rotate function, it would be a compiler error if you tried to call it on all objects of the class. Using dynamic_cast
, you can simulate the as
keyword. To be clear, if a cast fails, it returns an invalid pointer. So !test
is essentially a shorthand for checking if test
is NULL or an invalid pointer, which means the cast failed.
After seeing all the great things dynamic allocation can do, you're probably wondering why wouldn't anyone NOT use dynamic allocation all the time? I already told you one reason, the heap is slow. And if you don't need all that memory, you shouldn't abuse it. So here are some disadvantages in no particular order:
It is error-prone. Manual memory allocation is dangerous and you are prone to leaks. If you are not proficient at using the debugger or valgrind
(a memory leak tool), you may pull your hair out of your head. Luckily RAII idioms and smart pointers alleviate this a bit, but you must be familiar with practices such as The Rule Of Three and The Rule Of Five. It is a lot of information to take in, and beginners who either don't know or don't care will fall into this trap.
It is not necessary. Unlike Java and C# where it is idiomatic to use the new
keyword everywhere, in C++, you should only use it if you need to. The common phrase goes, everything looks like a nail if you have a hammer. Whereas beginners who start with C++ are scared of pointers and learn to use stack variables by habit, Java and C# programmers start by using pointers without understanding it! That is literally stepping off on the wrong foot. You must abandon everything you know because the syntax is one thing, learning the language is another.
1. (N)RVO - Aka, (Named) Return Value Optimization
One optimization many compilers make are things called elision and return value optimization. These things can obviate unnecessary copys which is useful for objects that are very large, such as a vector containing many elements. Normally the common practice is to use pointers to transfer ownership rather than copying the large objects to move them around. This has lead to the inception of move semantics and smart pointers.
If you are using pointers, (N)RVO does NOT occur. It is more beneficial and less error-prone to take advantage of (N)RVO rather than returning or passing pointers if you are worried about optimization. Error leaks can happen if the caller of a function is responsible for delete
ing a dynamically allocated object and such. It can be difficult to track the ownership of an object if pointers are being passed around like a hot potato. Just use stack variables because it is simpler and better.
I wrote this for strings AND functionality (I know it's not the question but I searched for it and got here), maybe it can be expanded.
String.prototype.contains = function(str) {
return this.indexOf(str) != -1;
};
String.prototype.containsAll = function(strArray) {
for (var i = 0; i < strArray.length; i++) {
if (!this.contains(strArray[i])) {
return false;
}
}
return true;
}
app.filter('filterMultiple', function() {
return function(items, filterDict) {
return items.filter(function(item) {
for (filterKey in filterDict) {
if (filterDict[filterKey] instanceof Array) {
if (!item[filterKey].containsAll(filterDict[filterKey])) {
return false;
}
} else {
if (!item[filterKey].contains(filterDict[filterKey])) {
return false;
}
}
}
return true;
});
};
});
Usage:
<li ng-repeat="x in array | filterMultiple:{key1: value1, key2:[value21, value22]}">{{x.name}}</li>

using var_dummp() actually not an error, it was placed just for debugging and will be removed on production code. But real place where zend_mm_heap was happened is the second place.
What I have seen many people do is this (it may not be the best approach, correct me if I am wrong):
The table which I am using in the example is given below(the table includes nicknames that you have given to your specific girlfriends. Each girlfriend has a unique id):
nicknames(id,seq_no,names)
Suppose, you want to store many nicknames under an id. This is why we have included a seq_no
field.
Now, fill these values to your table:
(1,1,'sweetheart'), (1,2,'pumpkin'), (2,1,'cutie'), (2,2,'cherry pie')
If you want to find all the names that you have given to your girl friend id 1 then you can use:
select names from nicknames where id = 1;
Why not just convert both strings to lowercase before you call find()
?
Notice:
Casting in Java isn't magic, it's you telling the compiler that an Object of type A is actually of more specific type B, and thus gaining access to all the methods on B that you wouldn't have had otherwise. You're not performing any kind of magic or conversion when performing casting, you're essentially telling the compiler "trust me, I know what I'm doing and I can guarantee you that this Object at this line is actually an <Insert cast type here>." For example:
Object o = "str";
String str = (String)o;
The above is fine, not magic and all well. The object being stored in o is actually a string, and therefore we can cast to a string without any problems.
There's two ways this could go wrong. Firstly, if you're casting between two types in completely different inheritance hierarchies then the compiler will know you're being silly and stop you:
String o = "str";
Integer str = (Integer)o; //Compilation fails here
Secondly, if they're in the same hierarchy but still an invalid cast then a ClassCastException
will be thrown at runtime:
Number o = new Integer(5);
Double n = (Double)o; //ClassCastException thrown here
This essentially means that you've violated the compiler's trust. You've told it you can guarantee the object is of a particular type, and it's not.
Why do you need casting? Well, to start with you only need it when going from a more general type to a more specific type. For instance, Integer
inherits from Number
, so if you want to store an Integer
as a Number
then that's ok (since all Integers are Numbers.) However, if you want to go the other way round you need a cast - not all Numbers are Integers (as well as Integer we have Double
, Float
, Byte
, Long
, etc.) And even if there's just one subclass in your project or the JDK, someone could easily create another and distribute that, so you've no guarantee even if you think it's a single, obvious choice!
Regarding use for casting, you still see the need for it in some libraries. Pre Java-5 it was used heavily in collections and various other classes, since all collections worked on adding objects and then casting the result that you got back out the collection. However, with the advent of generics much of the use for casting has gone away - it has been replaced by generics which provide a much safer alternative, without the potential for ClassCastExceptions (in fact if you use generics cleanly and it compiles with no warnings, you have a guarantee that you'll never get a ClassCastException.)
both are the same, but array_push makes a loop in it's parameter which is an array and perform $array[]=$element

This is a very highly upvoted issue request in Github for Floating Windows.
Until they support it, you can try the following workarounds:
The Duplicate Workspace in new Window Command was added in v1.24 (May 2018) to sort of address this.
workbench.action.duplicateWorkspaceInNewWindow
to Ctrl + Shift + N or whatever you'd likeRather than manually open a new window and dragging the file, you can do it all with a single command.
As AllenBooTung also pointed out, you can open/drag any file in a separate blank instance.
VS Code will not allow you to open the same folder in two different instances, but you can use Workspaces to open the same directory of files in a side by side instance.
For any workaround, also consider setting setting up auto save so the documents are kept in sync by updating the files.autoSave
setting to afterDelay
, onFocusChange
, or onWindowChange
Solution:
Within a custom ViewCellRenderer
you can set the SelectedBackgroundView
. Simply create a new UIView
with a background color of your choice and you're set.
public override UITableViewCell GetCell(Cell item, UITableViewCell reusableCell, UITableView tv)
{
var cell = base.GetCell(item, reusableCell, tv);
cell.SelectedBackgroundView = new UIView {
BackgroundColor = UIColor.DarkGray,
};
return cell;
}
Result:
Note:
With Xamarin.Forms it seems to be important to create a new UIView
rather than just setting the background color of the current one.
Solution:
The solution I found on Android is a bit more complicated:
Create a new drawable ViewCellBackground.xml
within the Resources
>drawable
folder:
<?xml version="1.0" encoding="UTF-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape android:shape="rectangle">
<solid android:color="#333333" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<solid android:color="#000000" />
</shape>
</item>
</selector>
It defines solid shapes with different colors for the default state and the "pressed" state of a UI element.
Use a inherited class for the View
of your ViewCell
, e.g.:
public class TouchableStackLayout: StackLayout
{
}
Implement a custom renderer for this class setting the background resource:
public class ElementRenderer: VisualElementRenderer<Xamarin.Forms.View>
{
protected override void OnElementChanged(ElementChangedEventArgs<Xamarin.Forms.View> e)
{
SetBackgroundResource(Resource.Drawable.ViewCellBackground);
base.OnElementChanged(e);
}
}
Result:
For those using the Google API Client Library for PHP and seeking offline access and refresh tokens beware as of the time of this writing the docs are showing incorrect examples.
currently it's showing:
$client = new Google_Client();
$client->setAuthConfig('client_secret.json');
$client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY);
$client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php');
// offline access will give you both an access and refresh token so that
// your app can refresh the access token without user interaction.
$client->setAccessType('offline');
// Using "consent" ensures that your application always receives a refresh token.
// If you are not using offline access, you can omit this.
$client->setApprovalPrompt("consent");
$client->setIncludeGrantedScopes(true); // incremental auth
source: https://developers.google.com/identity/protocols/OAuth2WebServer#offline
All of this works great - except ONE piece
$client->setApprovalPrompt("consent");
After a bit of reasoning I changed this line to the following and EVERYTHING WORKED
$client->setPrompt("consent");
It makes sense since using the HTTP requests it was changed from approval_prompt=force to prompt=consent. So changing the setter method from setApprovalPrompt to setPrompt follows natural convention - BUT IT'S NOT IN THE DOCS!!! That I found at least.
First, you're using the modifiers under an incorrect assumption.
Pattern.MULTILINE
or (?m)
tells Java to accept the anchors ^
and $
to match at the start and end of each line (otherwise they only match at the start/end of the entire string).
Pattern.DOTALL
or (?s)
tells Java to allow the dot to match newline characters, too.
Second, in your case, the regex fails because you're using the matches()
method which expects the regex to match the entire string - which of course doesn't work since there are some characters left after (\\W)*(\\S)*
have matched.
So if you're simply looking for a string that starts with User Comments:
, use the regex
^\s*User Comments:\s*(.*)
with the Pattern.DOTALL
option:
Pattern regex = Pattern.compile("^\\s*User Comments:\\s+(.*)", Pattern.DOTALL);
Matcher regexMatcher = regex.matcher(subjectString);
if (regexMatcher.find()) {
ResultString = regexMatcher.group(1);
}
ResultString
will then contain the text after User Comments:
You can use Cloudmersive native Java library. It is free for up to 50,000 conversions/month and is much higher fidelity in my experience than other things like iText or Apache POI-based methods. The documents actually look the same as they do in Microsoft Word which for me is the key. Incidentally it can also do XLSX, PPTX, and the legacy DOC, XLS and PPT conversion to PDF.
Here is what the code looks like, first add your imports:
import com.cloudmersive.client.invoker.ApiClient;
import com.cloudmersive.client.invoker.ApiException;
import com.cloudmersive.client.invoker.Configuration;
import com.cloudmersive.client.invoker.auth.*;
import com.cloudmersive.client.ConvertDocumentApi;
Then convert a file:
ApiClient defaultClient = Configuration.getDefaultApiClient();
// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
ConvertDocumentApi apiInstance = new ConvertDocumentApi();
File inputFile = new File("/path/to/input.docx"); // File to perform the operation on.
try {
byte[] result = apiInstance.convertDocumentDocxToPdf(inputFile);
System.out.println(result);
} catch (ApiException e) {
System.err.println("Exception when calling ConvertDocumentApi#convertDocumentDocxToPdf");
e.printStackTrace();
}
You can get an document conversion API key for free from the portal.

This can be accomplished by Unmarshaling into a map[string]json.RawMessage
.
var objmap map[string]json.RawMessage
err := json.Unmarshal(data, &objmap)
To further parse sendMsg
, you could then do something like:
var s sendMsg
err = json.Unmarshal(objmap["sendMsg"], &s)
For say
, you can do the same thing and unmarshal into a string:
var str string
err = json.Unmarshal(objmap["say"], &str)
EDIT: Keep in mind you will also need to export the variables in your sendMsg struct to unmarshal correctly. So your struct definition would be:
type sendMsg struct {
User string
Msg string
}

I fixed this problem.The device system version is older then the sdk minSdkVersion? I just modified the minSdkVersion from android_L to 19 to target my nexus 4.4.4.
buildscript {

sorry I don't have enough reputation to add pictures
The style
property lets you specify values for CSS properties.
The CSS width
property takes a length as its value.
Lengths require units. In quirks mode, browsers tend to assume pixels if provided with an integer instead of a length. Specify units.
e1.style.width = "400px";
I generally implement this usecase using org.apache.commons.lang3.builder.EqualsBuilder
Assert.assertTrue(EqualsBuilder.reflectionEquals(expected,actual));
Just like this:
string s="AbcdEf";
if(s.ToLower().Contains("def"))
{
Console.WriteLine("yes");
}
Here is the code for changing the color of ProgressBar by programatically.
ProgressBar progressBar = (ProgressBar) findViewById(R.id.pb_listProgressBar);
int colorCodeDark = Color.parseColor("#F44336");
progressBar.setIndeterminateTintList(ColorStateList.valueOf(colorCodeDark));
Please refer to update_attribute
. On clicking show source you will get following code
# File vendor/rails/activerecord/lib/active_record/base.rb, line 2614
2614: def update_attribute(name, value)
2615: send(name.to_s + '=', value)
2616: save(false)
2617: end
and now refer update_attributes
and look at its code you get
# File vendor/rails/activerecord/lib/active_record/base.rb, line 2621
2621: def update_attributes(attributes)
2622: self.attributes = attributes
2623: save
2624: end
the difference between two is update_attribute
uses save(false)
whereas update_attributes
uses save
or you can say save(true)
.
Sorry for the long description but what I want to say is important. save(perform_validation = true)
, if perform_validation
is false it bypasses (skips will be the proper word) all the validations associated with save
.
For second question
Also, what is the correct syntax to pass a hash to update_attributes... check out my example at the top.
Your example is correct.
Object.update_attributes(:field1 => "value", :field2 => "value2", :field3 => "value3")
or
Object.update_attributes :field1 => "value", :field2 => "value2", :field3 => "value3"
or if you get all fields data & name in a hash say params[:user]
here use just
Object.update_attributes(params[:user])
Here's an updated version (Swift 3.0.1) from Ben Packard's answer.
import UIKit
@IBDesignable class BorderedButton: UIButton {
@IBInspectable var borderColor: UIColor? {
didSet {
if let bColor = borderColor {
self.layer.borderColor = bColor.cgColor
}
}
}
@IBInspectable var borderWidth: CGFloat = 0 {
didSet {
self.layer.borderWidth = borderWidth
}
}
override var isHighlighted: Bool {
didSet {
guard let currentBorderColor = borderColor else {
return
}
let fadedColor = currentBorderColor.withAlphaComponent(0.2).cgColor
if isHighlighted {
layer.borderColor = fadedColor
} else {
self.layer.borderColor = currentBorderColor.cgColor
let animation = CABasicAnimation(keyPath: "borderColor")
animation.fromValue = fadedColor
animation.toValue = currentBorderColor.cgColor
animation.duration = 0.4
self.layer.add(animation, forKey: "")
}
}
}
}
The resulting button can be used inside your StoryBoard thanks to the @IBDesignable
and @IBInspectable
tags.
Also the two properties defined, allow you to set the border width and color directly on interface builder and preview the result.
Other properties could be added in a similar fashion, for border radius and highlight fading time.
Your .profile
or .bash_profile
are simply files that are present in your "home" folder. If you open a Finder window and click your account name in the Favorites pane, you won't see them. If you open a Terminal window and type ls
to list files you still won't see them. However, you can find them by using ls -a
in the terminal. Or if you open your favorite text editor (say TextEdit since it comes with OS X) and do File->Open and then press Command+Shift+. and click on your account name (home folder) you will see them as well. If you do not see them, then you can create one in your favorite text editor.
Now, adding environment variables is relatively straightforward and remarkably similar to windows conceptually. In your .profile
just add, one per line, the variable name and its value as follows:
export JAVA_HOME=/Library/Java/Home
export JRE_HOME=/Library/Java/Home
etc.
If you are modifying your "PATH" variable, be sure to include the system's default PATH that was already set for you:
export PATH=$PATH:/path/to/my/stuff
Now here is the quirky part, you can either open a new Terminal window to have the new variables take effect, or you will need to type .profile
or .bash_profile
to reload the file and have the contents be applied to your current Terminal's environment.
You can check that your changes took effect using the "set" command in your Terminal. Just type set
(or set | more
if you prefer a paginated list) and be sure what you added to the file is there.
As for adding environment variables to GUI apps, that is normally not necessary and I'd like to hear more about what you are specifically trying to do to better give you an answer for it.
Don’t need to specify a type
value of “text/css”
Every time you link to a CSS file:
<link rel="stylesheet" type="text/css" href="file.css">
You can simply write:
<link rel="stylesheet" href="file.css">
Belonging to other reply, I have added condition clause for getting null.
string ComingUrl = "";
if (Request.UrlReferrer != null)
{
ComingUrl = System.Web.HttpContext.Current.Request.UrlReferrer.ToString();
}
else
{
ComingUrl = "Direct"; // Your code
}
Not an exact answer to your question, but a bit of information: if your device does use NTP for time (eg. if it is a tablet with no 3G or GPS capabilities), the server can be configured in /system/etc/gps.conf
- obviously this file can only be edited with root access, but is viewable on non-rooted devices.
Best strategy is to design your site to build a unique URL to your JS files, that gets reset every time there is a change. That way it caches when there has been no change, but imediately reloads when any change occurs.
You'd need to adjust for your specific environment tools, but if you are using PHP/Apache, here's a great solution for both you, and the end-users.

You'll need to use UNION
to combine the results of two queries. In your case:
SELECT ChargeNum, CategoryID, SUM(Hours)
FROM KnownHours
GROUP BY ChargeNum, CategoryID
UNION ALL
SELECT ChargeNum, 'Unknown' AS CategoryID, SUM(Hours)
FROM UnknownHours
GROUP BY ChargeNum
Note - If you use UNION ALL
as in above, it's no slower than running the two queries separately as it does no duplicate-checking.
You can use stristr()
or strpos()
. Both return false if nothing is found.
This
public static bool GetBit(this byte b, int bitNumber) {
return (b & (1 << bitNumber)) != 0;
}
should do it, I think.
Imagine your task is to classify a speech to a language.
You can do it by either:

The first one is the generative approach and the second one is the discriminative approach.
Check this reference for more details: http://www.cedar.buffalo.edu/~srihari/CSE574/Discriminative-Generative.pdf.
Or with the power of Java 8 Optional, you also can do such trick:
Optional.ofNullable(boolValue).orElse(false)

the file name10Y (!) had passed since this was asked, and still I see no mention of MS's good, non-GPL'ed solution: IMultiLanguage2 API.
Most libraries already mentioned are based on Mozilla's UDE - and it seems reasonable that browsers have already tackled similar problems. I don't know what is chrome's solution, but since IE 5.0 MS have released theirs, and it is:
It is a native COM call, but here's some very nice work by Carsten Zeumer, that handles the interop mess for .net usage. There are some others around, but by and large this library doesn't get the attention it deserves.
You may need user name and password:
mysqlcheck -A --auto-repair -uroot -p
You will be prompted for password.

Yes, use the commercial but inexpensive SSMS Tools Pack addin which has a nifty "Generate Insert statements from resultsets, tables or database" feature
String.equalsIgnoreCase
is the most practical choice for naive case-insensitive string comparison.
However, it is good to be aware that this method does neither do full case folding nor decomposition and so cannot perform caseless matching as specified in the Unicode standard. In fact, the JDK APIs do not provide access to information about case folding character data, so this job is best delegated to a tried and tested third-party library.
That library is ICU, and here is how one could implement a utility for case-insensitive string comparison:
import com.ibm.icu.text.Normalizer2;
// ...
public static boolean equalsIgnoreCase(CharSequence s, CharSequence t) {
Normalizer2 normalizer = Normalizer2.getNFKCCasefoldInstance();
return normalizer.normalize(s).equals(normalizer.normalize(t));
}
String brook = "?u\u0308ßchen";
String BROOK = "FLÜSSCHEN";
assert equalsIgnoreCase(brook, BROOK);
Naive comparison with String.equalsIgnoreCase
, or String.equals
on upper- or lowercased strings will fail even this simple test.
(Do note though that the predefined case folding flavour getNFKCCasefoldInstance
is locale-independent; for Turkish locales a little more work involving UCharacter.foldCase
may be necessary.)
You can use the following code to add column to Datatable at postion 0:
DataColumn Col = datatable.Columns.Add("Column Name", System.Type.GetType("System.Boolean"));
Col.SetOrdinal(0);// to put the column in position 0;
If your numbers are a, b and c then:
int a = 1;
int b = 2;
int c = 3;
int d = a > b ? a : b;
return c > d ? c : d;
This could turn into one of those "how many different ways can we do this" type questions!
You can use: $counter = count($datas);
It basically is higher/greater in everything else. A keyboard is less of a priority than the real time process. This means the process will be taken into account faster then keyboard and if it can't handle that, then your keyboard is slowed.
Since you want to append elements to existing list, you can use var List[Int] and then keep on adding elements to the same list. Note -> You have to make sure that you insert an element into existing list as follows:-
var l: List[int] = List() // creates an empty list
l = 3 :: l // adds 3 to the head of the list
l = 4 :: l // makes int 4 as the head of the list
// Now when you will print l, you will see two elements in the list ( 4, 3)
If the CSV file must be imported as part of a python program, then for simplicity and efficiency, you could use os.system
along the lines suggested by the following:
import os
cmd = """sqlite3 database.db <<< ".import input.csv mytable" """
rc = os.system(cmd)
print(rc)
The point is that by specifying the filename of the database, the data will automatically be saved, assuming there are no errors reading it.
The accepted answers gives the code for a histogram with overlapping bars, but in case you want each bar to be side-by-side (as I did), try the variation below:
import numpy as np
import matplotlib.pyplot as plt
plt.style.use('seaborn-deep')
x = np.random.normal(1, 2, 5000)
y = np.random.normal(-1, 3, 2000)
bins = np.linspace(-10, 10, 30)
plt.hist([x, y], bins, label=['x', 'y'])
plt.legend(loc='upper right')
plt.show()

EDIT [2018/03/16]: Updated to allow plotting of arrays of different sizes, as suggested by @stochastic_zeitgeist
include dirname(__FILE__).'/../../index.php';
is your best bet here, and it will avoid most of the relative path bugs you can encounter with other solutions.
Indeed, it will force the include to always be relative to the position of the current script where this code is placed (which location is most likely stable, since you define the architecture of your application). This is different from just doing include '../../index.php'
which will include relatively to the executing (also named "calling") script and then relatively to the current working directory, which will point to the parent script that includes your script, instead of resolving from your included script's path.
From the PHP documentation:
Files are included based on the file path given or, if none is given, the include_path specified. If the file isn't found in the include_path, include will finally check in the calling script's own directory and the current working directory before failing.
And the oldest post I've found citing this trick dates back to 2003, by Tapken.
You can test with the following setup:
Create a layout like this:
htdocs
¦ parent.php
¦ goal.php
¦
+---sub
¦ included.php
¦ goal.php
In parent.php
, put:
<?php
include dirname(__FILE__).'/sub/included.php';
?>
In sub/included.php
, put:
<?php
print("WRONG : " . realpath('goal.php'));
print("GOOD : " . realpath(dirname(__FILE__).'/goal.php'));
?>
Result when accessing parent.php
:
WRONG : X:\htdocs\goal.php
GOOD : X:\htdocs\sub\goal.php
As we can see, in the first case, the path is resolved from the calling script parent.php
, while by using the dirname(__FILE__).'/path'
trick, the include is done from the script included.php
where the code is placed in.
Beware, the following NOT equivalent to the trick above contrary to what can be read elsewhere:
include '/../../index.php';
Indeed, prepending /
will work, but it will resolve just like include ../../index.php
from the calling script (the difference is that include_path
won't be looked afterwards if it fails). From PHP doc:
If a path is defined — whether absolute (starting with a drive letter or \ on Windows, or / on Unix/Linux systems) or relative to the current directory (starting with . or ..) — the include_path will be ignored altogether.
You can use numpy's slicing, simply start:stop:step
.
>>> xs
array([1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4])
>>> xs[1::4]
array([2, 2, 2])
This creates a view of the the original data, so it's constant time. It'll also reflect changes to the original array and keep the whole original array in memory:
>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2] # O(1), constant time
>>> b[:] = 0 # modifying the view changes original array
>>> a # original array is modified
array([0, 2, 0, 4, 0])
so if either of the above things are a problem, you can make a copy explicitly:
>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2].copy() # explicit copy, O(n)
>>> b[:] = 0 # modifying the copy
>>> a # original is intact
array([1, 2, 3, 4, 5])
This isn't constant time, but the result isn't tied to the original array. The copy also contiguous in memory, which can make some operations on it faster.
I know I'm late to the party, but I thought I would provide an answer here for people who need to horizontally position an absolute item, when you don't know its exact width.
Try this:
// Horizontal example.
div#thing {
position: absolute;
left: 50%;
transform: translateX(-50%);
}
The same technique can also be applied, for when you might need vertical alignment, simply by adjusting the properties like so:
// Vertical example.
div#thing {
position: absolute;
top: 50%;
transform: translateY(-50%);
}
On Ubuntu until python-distribute is something newer than 0.7 I'd recommend:
$ wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | sudo python
See http://reinout.vanrees.org/weblog/2013/07/08/new-setuptools-buildout.html
here is another solution I started using after being fed up with the copy and paste issue:
vmrun start D:\VM\MySuperVM1\vm1.vmx nogui vmrun start D:\VM\MySuperVM2\vm2.vmx nogui
save the file to startmyvms.cmd
create another batch file and add your vms
vmrun stop D:\VM\MySuperVM1\vm1.vmx nogui vmrun stop D:\VM\MySuperVM2\vm2.vmx nogui
save the file to stopmyvms.cmd
Open Mremote go to tools => External tools Add external tool => filename will be the startmyvms.cmd file Add external tool => filename will be the stopmyvms.cmd file So to start working with your vms:
Create you connections to your VMs in mremote
Now to work with your vm 1. You open mremote 2. You go to tools => external tools 3. You click the startmyvms tool when you're done 1. You go to tools => external tools 2. You click the stopmyvms external tool
you could add the vmrun start on the connection setting => external tool before connection and add the vmrun stop in the connection settings => external tool after
Voilà !
There's no exact counterpart to Java's getClass()
in JavaScript. Mostly that's due to JavaScript being a prototype-based language, as opposed to Java being a class-based one.
Depending on what you need getClass()
for, there are several options in JavaScript:
typeof
instanceof
obj.
constructor
func.
prototype
, proto
.isPrototypeOf
A few examples:
function Foo() {}
var foo = new Foo();
typeof Foo; // == "function"
typeof foo; // == "object"
foo instanceof Foo; // == true
foo.constructor.name; // == "Foo"
Foo.name // == "Foo"
Foo.prototype.isPrototypeOf(foo); // == true
Foo.prototype.bar = function (x) {return x+x;};
foo.bar(21); // == 42
Note: if you are compiling your code with Uglify it will change non-global class names. To prevent this, Uglify has a --mangle
param that you can set to false is using gulp or grunt.
A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.
This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.
Whereas a GridLayout is a layout that places its children in a rectangular grid.
It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.
You can omit the import statements and refer to them using the entire path. Eg:
java.util.Date javaDate = new java.util.Date()
my.own.Date myDate = new my.own.Date();
But I would say that using two classes with the same name and a similiar function is usually not the best idea unless you can make it really clear which is which.
There's no such thing as a “good hash function” for universal hashes (ed. yes, I know there's such a thing as “universal hashing” but that's not what I meant). Depending on the context different criteria determine the quality of a hash. Two people already mentioned SHA. This is a cryptographic hash and it isn't at all good for hash tables which you probably mean.
Hash tables have very different requirements. But still, finding a good hash function universally is hard because different data types expose different information that can be hashed. As a rule of thumb it is good to consider all information a type holds equally. This is not always easy or even possible. For reasons of statistics (and hence collision), it is also important to generate a good spread over the problem space, i.e. all possible objects. This means that when hashing numbers between 100 and 1050 it's no good to let the most significant digit play a big part in the hash because for ~ 90% of the objects, this digit will be 0. It's far more important to let the last three digits determine the hash.
Similarly, when hashing strings it's important to consider all characters – except when it's known in advance that the first three characters of all strings will be the same; considering these then is a waste.
This is actually one of the cases where I advise to read what Knuth has to say in The Art of Computer Programming, vol. 3. Another good read is Julienne Walker's The Art of Hashing.
I had a similar problem where i have to center the toolTip. React setState in componentDidUpdate did put me in infinite loop, i tried condition it worked. But i found using in ref callback gave me simpler and clean solution, if you use inline function for ref callback you will face the null problem for every component update. So use function reference in ref callback and set the state there, which will initiate the re-render
(This is pointed out in a comment by Zan Lynx, but I think it deserves an aswer - given that the accepted answer doesn't mention it).
The essential difference between puts(mystr);
and printf(mystr);
is that in the latter the argument is interpreted as a formatting string. The result will be often the same (except for the added newline) if the string doesn't contain any control characters (%
) but if you cannot rely on that (if mystr
is a variable instead of a literal) you should not use it.
So, it's generally dangerous -and conceptually wrong- to pass a dynamic string as single argument of printf
:
char * myMessage;
// ... myMessage gets assigned at runtime, unpredictable content
printf(myMessage); // <--- WRONG! (what if myMessage contains a '%' char?)
puts(myMessage); // ok
printf("%s\n",myMessage); // ok, equivalent to the previous, perhaps less efficient
The same applies to fputs
vs fprintf
(but fputs
doesn't add the newline).
Say the 1st date is in A1 cell
& the 2nd date is in B1 cell
Make sure that the cell type of both A1
& B1
is DATE
.
Then simply put the following formula in C1:
=A1-B1
The result of this formula may look funny to you.
Then Change the Cell type of C1
to GENERAL
.
It will give you the difference in Days.
You can also use this formula to get the remaining days of year or change the formula as you need:
=365-(A1-B1)
Before MVC 5 you could map URLs to specific actions and controllers by calling routes.MapRoute(...)
in the RouteConfig.cs file. This is where the url for the homepage is stored (Home/Index
). However if you modify the default route as shown below,
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
keep in mind that this will affect the URLs of other actions and controllers. For example, if you had a controller class named ExampleController
and an action method inside of it called DoSomething
, then the expected default url ExampleController/DoSomething
will no longer work because the default route was changed.
A workaround for this is to not mess with the default route and create new routes in the RouteConfig.cs file for other actions and controllers like so,
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Example",
url: "hey/now",
defaults: new { controller = "Example", action = "DoSomething", id = UrlParameter.Optional }
);
Now the DoSomething
action of the ExampleController
class will be mapped to the url hey/now
. But this can get tedious to do for every time you want to define routes for different actions. So in MVC 5 you can now add attributes to match urls to actions like so,
public class HomeController : Controller
{
// url is now 'index/' instead of 'home/index'
[Route("index")]
public ActionResult Index()
{
return View();
}
// url is now 'create/new' instead of 'home/create'
[Route("create/new")]
public ActionResult Create()
{
return View();
}
}
Use the following:
/**
* Utility method to replace the string from StringBuilder.
* @param sb the StringBuilder object.
* @param toReplace the String that should be replaced.
* @param replacement the String that has to be replaced by.
*
*/
public static void replaceString(StringBuilder sb,
String toReplace,
String replacement) {
int index = -1;
while ((index = sb.lastIndexOf(toReplace)) != -1) {
sb.replace(index, index + toReplace.length(), replacement);
}
}
I know this is an old question, but I wanted to add something to the answers already here in hopes of helping someone else.
You can script the ftp
command with the -s:filename
option. The syntax is just a list of commands to pass to the ftp
shell, each terminated by a newline. This page has a nice reference to the commands that can be performed with ftp
.
Using the normal ftp
doesn't work very well when you need to have an entire directory tree copied to or from a ftp site. So you could use something like these to handle those situations.
These scripts works with the Windows ftp
command and allows for uploading and downloading of entire directories from a single command. This makes it pretty self reliant when using on different systems.
Basically what they do is map out the directory structure to be up/downloaded, dump corresponding ftp
commands to a file, then execute those commands when the mapping has finished.

If you had caught the error, you would have seen this:
jsonString, err := json.Marshal(datas)
fmt.Println(err)
// [] json: unsupported type: map[int]main.Foo
The thing is you cannot use integers as keys in JSON; it is forbidden. Instead, you can convert these values to strings beforehand, for instance using strconv.Itoa
.

If you are looking for a modern >1.7 Dojo way of destroying all node's children this is the way:
// Destroys all domNode's children nodes
// domNode can be a node or its id:
domConstruct.empty(domNode);
Safely empty the contents of a DOM element. empty() deletes all children but keeps the node there.
Check "dom-construct" documentation for more details.
// Destroys domNode and all it's children
domConstruct.destroy(domNode);
Destroys a DOM element. destroy() deletes all children and the node itself.
Short answer: Don't do it.
Longer answer: Use WCF. It's here to replace Asmx.
see this answer for example, or the first comment on this one.
John Saunders: ASMX is a legacy technology, and should not be used for new development. WCF or ASP.NET Web API should be used for all new development of web service clients and servers. One hint: Microsoft has retired the ASMX Forum on MSDN.
As for comment ... well, if you have to, you have to. I'll leave you in the competent hands of the other answers then. (Even though it's funny it has issues, and if it does, why are you doing it in VS2013 to begin with ?)
Type "gg" in command mode. This brings the cursor to the first line.
Please make sure the output folder in Java Build Path
tab set as like below,which would determine where the .class file are generated.Then clean the project.
One option is to use Python's slicing and indexing features to logically evaluate the places where your condition holds and overwrite the data there.
Assuming you can load your data directly into pandas
with pandas.read_csv
then the following code might be helpful for you.
import pandas
df = pandas.read_csv("test.csv")
df.loc[df.ID == 103, 'FirstName'] = "Matt"
df.loc[df.ID == 103, 'LastName'] = "Jones"
As mentioned in the comments, you can also do the assignment to both columns in one shot:
df.loc[df.ID == 103, ['FirstName', 'LastName']] = 'Matt', 'Jones'
Note that you'll need pandas
version 0.11 or newer to make use of loc
for overwrite assignment operations.
Another way to do it is to use what is called chained assignment. The behavior of this is less stable and so it is not considered the best solution (it is explicitly discouraged in the docs), but it is useful to know about:
import pandas
df = pandas.read_csv("test.csv")
df['FirstName'][df.ID == 103] = "Matt"
df['LastName'][df.ID == 103] = "Jones"
The wb
indicates that the file is opened for writing in binary mode.
When writing in binary mode, Python makes no changes to data as it is written to the file. In text mode (when the b
is excluded as in just w
or when you specify text mode with wt
), however, Python will encode the text based on the default text encoding. Additionally, Python will convert line endings (\n
) to whatever the platform-specific line ending is, which would corrupt a binary file like an exe
or png
file.
Text mode should therefore be used when writing text files (whether using plain text or a text-based format like CSV), while binary mode must be used when writing non-text files like images.

I'm arriving a bit late to the party, but I've got three four five:
If you poll InvokeRequired on a control that hasn't been loaded/shown, it will say false - and blow up in your face if you try to change it from another thread (the solution is to reference this.Handle in the creator of the control).
Another one which tripped me up is that given an assembly with:
enum MyEnum
{
Red,
Blue,
}
if you calculate MyEnum.Red.ToString() in another assembly, and in between times someone has recompiled your enum to:
enum MyEnum
{
Black,
Red,
Blue,
}
at runtime, you will get "Black".
I had a shared assembly with some handy constants in. My predecessor had left a load of ugly-looking get-only properties, I thought I'd get rid of the clutter and just use public const. I was more than a little surprised when VS compiled them to their values, and not references.
If you implement a new method of an interface from another assembly, but you rebuild referencing the old version of that assembly, you get a TypeLoadException (no implementation of 'NewMethod'), even though you have implemented it (see here).
Dictionary<,>: "The order in which the items are returned is undefined". This is horrible, because it can bite you sometimes, but work others, and if you've just blindly assumed that Dictionary is going to play nice ("why shouldn't it? I thought, List does"), you really have to have your nose in it before you finally start to question your assumption.

dupes.push(val);

tmp[JSON.stringify(val)] = true;
}
return justCheck ? false : dupes.length ? dupes : null;

chkDuplicates([{a:1,b:2},1,2,3,4,{a:1,b:2},[1,2,3]],true); //=> true
chkDuplicates([null,1,2,3,4,{a:1,b:2},NaN],true); //=> false
chkDuplicates([1,2,3,4,5,1,2]); //=> [1,2]
chkDuplicates([1,2,3,4,5]); //=> null

It looks like you don't have any records that match your query, so you'd want to return an empty array (or null or something) if the number of rows == 0.
It seems in general you're just looking for a join:
> dat1 = pd.DataFrame({'dat1': [9,5]})
> dat2 = pd.DataFrame({'dat2': [7,6]})
> dat1.join(dat2)
dat1 dat2

If your grep -i does not work then try using tr command to convert the the output of your file to lower case and then pipe it into standard grep with whatever you are looking for. (it sounds complicated but the actual command which I have provided for you is not !).
Notice the tr command does not change the content of your original file, it just converts it just before it feeds it into grep.
1.here is how you can do this on a file
tr '[:upper:]' '[:lower:]' <your_file.txt|grep what_ever_you_are_searching_in_lower_case
2.or in your case if you are just echoing something
echo "ABC"|tr '[:upper:]' '[:lower:]' | grep abc
You can first find the position of the string in this case ":"
'position = InStr(StringToSearch, StringToFind)
position = InStr(StringToSearch, ":")
Then use Left(StringToCut, NumberOfCharacterToCut)
Result = Left(StringToSearch, position -1)

For me This was the solution on macOS ReInstall the psql
brew install postgres
Start PostgreSQL server
pg_ctl -D /usr/local/var/postgres start
Initialize DB
initdb /usr/local/var/postgres
If this command throws an error the rm the old database file and re-run the above command
rm -r /usr/local/var/postgres
Create a new database
createdb postgres_test
psql -W postegres_test
You will be logged into this db and can create a user in here to login
I often include a function called run() to handle errors. Every call I want to make is passed to this function so the entire script exits when a failure is hit. The advantage of this over the set -e solution is that the script doesn't exit silently when a line fails, and can tell you what the problem is. In the following example, the 3rd line is not executed because the script exits at the call to false.
function run() {
cmd_output=$(eval $1)
return_value=$?
if [ $return_value != 0 ]; then
echo "Command $1 failed"
exit -1
else
echo "output: $cmd_output"
echo "Command succeeded."
fi
return $return_value
}
run "date"
run "false"
run "date"
You need to create a handler for the onkeypress

{
var charCode;
//Get key code (support for all browsers)
if(e && e.which)
{
charCode = e.which;
}
else if(window.event)
{
e = window.event;
charCode = e.keyCode;
}
if(charCode == 13)
{
//Call your submit function
}

Now python gives you the choice to install pip
during the installation (I am on Windows, and at least python does so for Windows!). Considering you had chosen to install pip
during installation of python (you don't actually have to choose because it is default), pip
is already installed for you. Then, type in pip
in command prompt, you should see a help come up. You can find necessary usage instructions there. E.g. pip list
shows you the list of installed packages. You can use
pip uninstall package_name
to uninstall any package that you don't want anymore. Read more here (pip documentation).

Full sync has few tasks:
git reset HEAD --hard
git clean -f
git pull origin master
Or else, what I prefer is that, I may create a new branch with the latest from the remote using:
git checkout origin/master -b <new branch name>
origin is my remote repository reference, and master is my considered branch name. These may different from yours.

console.log("clearing cookies for: "+testURL);

jar.clear(objURL, function (error) {
// error - <Error>
if(error)
console.log("Error clearing cookies: "+error);

The following is a group of versatile C functions for timer management based on the gettimeofday() system call. All the timer properties are contained in a single ticktimer struct - the interval you want, the total running time since the timer initialization, a pointer to the desired callback you want to call, the number of times the callback was called. A callback function would look like this:
void your_timer_cb (struct ticktimer *t) {
/* do your stuff here */
}
To initialize and start a timer, call ticktimer_init(your_timer, interval, TICKTIMER_RUN, your_timer_cb, 0).
In the main loop of your program call ticktimer_tick(your_timer) and it will decide whether the appropriate amount of time has passed to invoke the callback.
To stop a timer, just call ticktimer_ctl(your_timer, TICKTIMER_STOP).

The recent openssh version deprecated DSA keys by default. You should suggest to your GIT provider to add some reasonable host key. Relying only on DSA is not a good idea.
As a workaround, you need to tell your ssh
client that you want to accept DSA host keys, as described in the official documentation for legacy usage. You have few possibilities, but I recommend to add these lines into your ~/.ssh/config
file:
Host your-remote-host
HostkeyAlgorithms +ssh-dss
Other possibility is to use environment variable GIT_SSH
to specify these options:
GIT_SSH_COMMAND="ssh -oHostKeyAlgorithms=+ssh-dss" git clone ssh://user@host/path-to-repository
Your last example is invalid JSON. Single quotes are not allowed in JSON except inside strings. In the second example, the single quotes are not in the string, but serve to show the start and end.
See http://www.json.org/ for the specifications.
Should add: Why do you think this: "like I seem to need to in my real code"? Then maybe we can help you come up with the solution.
Turn on Client Statistics by doing one of the following:
Then you get a new tab which records the timings, IO data and rowcounts etc for (up to) the last 10 exections (plus averages!):
Just use the constructor for the vector that takes iterators:
std::set<T> s;
//...
std::vector v( s.begin(), s.end() );
Assumes you just want the content of s in v, and there's nothing in v prior to copying the data to it.
For me the code:
<form (submit)="addTodo()">_x000D_
<input type="text" [(ngModel)]="text">_x000D_
</form>
_x000D_
throws error, but I added name attribute to input:
<form (submit)="addTodo()">_x000D_
<input type="text" [(ngModel)]="text" name="text">_x000D_
</form>
_x000D_
and it started to work.
I know nothing about the Python interpreter inner workings (and I'm not an expert in compilers and interpreters either) so don't blame me if I propose anything unsensible or impossible.
Provided that python objects are mutable I think that this should be taken into account when designing the default arguments stuff. When you instantiate a list:
a = []
you expect to get a new list referenced by a
.
Why should the a=[]
in
def x(a=[]):
instantiate a new list on function definition and not on invocation? It's just like you're asking "if the user doesn't provide the argument then instantiate a new list and use it as if it was produced by the caller". I think this is ambiguous instead:
def x(a=datetime.datetime.now()):
user, do you want a
to default to the datetime corresponding to when you're defining or executing x
?
In this case, as in the previous one, I'll keep the same behaviour as if the default argument "assignment" was the first instruction of the function (datetime.now()
called on function invocation).
On the other hand, if the user wanted the definition-time mapping he could write:
b = datetime.datetime.now()
def x(a=b):
I know, I know: that's a closure. Alternatively Python might provide a keyword to force definition-time binding:
def x(static a=b):
Use the android:drawableLeft
property on the EditText.
<EditText
...
android:drawableLeft="@drawable/my_icon" />
If your solution doesn't have to be general, i.e. only needs to work for strings like your example, you could do:
var1=$(echo $STR | cut -f1 -d-)
var2=$(echo $STR | cut -f2 -d-)
I chose cut
here because you could simply extend the code for a few more variables...
No, It is not possible. But if you want to dig it more, then you can visit Using Android phone as GSM Gateway for VoIP where author has concluded that
It's not possible to use Android as a GSM Gateway in its current form. Even after flashing custom ROM because they also depends on proprietary RIL (Radio Interface Layer) firmwares. Hurdles 1 and 2 (API limitation) can be removed because the source code is available for the open source community to make it possible. However, the hurdle 3 (proprietary RIL) is dependent on the hardware vendors. Hardware vendors do not usually make their device drivers code available.
Take a look at CBFG
and the Android port of the loading/rendering
code. You should be able to drop the code into your project and use it
straight away.

Updating a Specific Library - scikit-learn
:
Anaconda (conda
):
conda install scikit-learn
Pip Installs Packages (pip
):
pip install --upgrade scikit-learn
Verify Update:
conda list scikit-learn
It should now display the current (and desired) version of the scikit-learn
library.
For me personally, I tried using the conda
command to update the scikit-learn
library and it acted as if it were installing the latest version to then later discover (with an execution of the conda list scikit-learn
command) that it was the same version as previously and never updated (or recognized the update?). When I used the pip
command, it worked like a charm and correctly updated the scikit-learn
library to the latest version!

It works well on my Ubuntu.
For your example, you'd add this:

printArea():void;
}
Edit: oops, basarat is correct below. I'm not sure why I thought it was compiling but I've updated this answer.
The chosen answer looks like does not apply to modern browsers, at least on Firefox 52. What I observed is that the requests of loading resources like css, javascript are issued before HTML parser reaches the element, for example
<html>
<head>
<!-- prints the date before parsing and blocks HTMP parsering -->
<script>
console.log("start: " + (new Date()).toISOString());
for(var i=0; i<1000000000; i++) {};
</script>
<script src="jquery.js" type="text/javascript"></script>
<script src="abc.js" type="text/javascript"></script>
<link rel="stylesheets" type="text/css" href="abc.css"></link>
<style>h2{font-wight:bold;}</style>
<script>
$(document).ready(function(){
$("#img").attr("src", "kkk.png");
});
</script>
</head>
<body>
<img id="img" src="abc.jpg" style="width:400px;height:300px;"/>
<script src="kkk.js" type="text/javascript"></script>
</body>
</html>
What I found that the start time of requests to load css and javascript resources were not being blocked. Looks like Firefox has a HTML scan, and identify key resources(img resource is not included) before starting to parse the HTML.
There is loads of vim tricks but as of now, the one that I really enjoy is Ctrl+A as I happen to be dealing with some st**d code that hard-code array index.

From the C# language specification (PDF page 287 - or 300th page of the PDF):
Even though constants are considered static members, a constant declaration neither requires nor allows a static modifier.
People like me who are looking for something like this in in build:
<script type="text/javascript" src="https://dsomething.cloudfront.net/static/js/main.ec7f8972.js">
Then setting https://dsomething.cloudfront.net
to homepage
in package.json
will not work.
Build your project like this:
(windows)
set PUBLIC_URL=https://dsomething.cloudfront.net&&npm run build
(linux/mac)
PUBLIC_URL=https://dsomething.cloudfront.net npm run build
And you will get
<script type="text/javascript" src="https://dsomething.cloudfront.net/static/js/main.ec7f8972.js">
in your built index.html
Create a file called .env
at your project root(same place where package.json is located).
In this file write this(no quotes around the url):
PUBLIC_URL=https://dsomething.cloudfront.net
Build your project as usual (npm run build
)
This will also generate index.html with:
<script type="text/javascript" src="https://dsomething.cloudfront.net/static/js/main.ec7f8972.js">
Add this in your package.json
"homepage": "http://://dsomething.cloudfront.net",
Then index.html will be generated with:
<script type="text/javascript" src="//dsomething.cloudfront.net/static/js/main.ec7f8972.js">
Which is basically the same as:
<script type="text/javascript" src="https://dsomething.cloudfront.net/static/js/main.ec7f8972.js">
in my understanding.
Git comes with a couple of GUI clients that helps you visualize this. Open GitGUI and go to menu Repository > Visualize All Branch History
You will get the following error message too when you provide undefined or so to an operator which expects an Observable, eg. takeUntil.
TypeError: You provided an invalid object where a stream was expected. You can provide an Observable, Promise, Array, or Iterable
This is what's killing you:
task.Wait();
That's blocking the UI thread until the task has completed - but the task is an async method which is going to try to get back to the UI thread after it "pauses" and awaits an async result. It can't do that, because you're blocking the UI thread...
There's nothing in your code which really looks like it needs to be on the UI thread anyway, but assuming you really do want it there, you should use:
private async void Button_Click(object sender, RoutedEventArgs
{
Task<List<MyObject>> task = GetResponse<MyObject>("my url");
var items = await task;
// Presumably use items here
}
Or just:
private async void Button_Click(object sender, RoutedEventArgs
{
var items = await GetResponse<MyObject>("my url");
// Presumably use items here
}
Now instead of blocking until the task has completed, the Button_Click
method will return after scheduling a continuation to fire when the task has completed. (That's how async/await works, basically.)
Note that I would also rename GetResponse
to GetResponseAsync
for clarity.
this is an out of topic answer, but, for those who are interested, it maybe valuable.
As in @John Kugelman's answer, % is related to job specification. how to efficiently find that? use less's &pattern command, seems man use less pager (not that sure), in man bash type &% then type Enter will only show lines that containing '%', to reshow all, type &. then Enter.
I believe, the 500ms run in the background, while the rest of the code continues to execute and empties the list.
Then after 500ms nothing happens, as no function-call is implemented in the after-callup (same as frame.after(500, function=None)
)
using (SqlConnection conn = new SqlConnection("Server=(local);DataBase=Northwind;Integrated Security=SSPI")) {
conn.Open();
// 1. create a command object identifying the stored procedure
SqlCommand cmd = new SqlCommand("CustOrderHist", conn);
// 2. set the command object so it knows to execute a stored procedure
cmd.CommandType = CommandType.StoredProcedure;
// 3. add parameter to command, which will be passed to the stored procedure
cmd.Parameters.Add(new SqlParameter("@CustomerID", custId));
// execute the command
using (SqlDataReader rdr = cmd.ExecuteReader()) {
// iterate through results, printing each to console
while (rdr.Read())
{
Console.WriteLine("Product: {0,-35} Total: {1,2}",rdr["ProductName"],rdr["Total"]);
}
}
}
Here are some interesting links you could read:
I would use a duplex stream instead. like documented here nodejs doc duplex streams
A Transform stream is a Duplex stream where the output is computed in some way from the input.
Since jQuery 3.3.0, it is possible to pass arrays to .addClass()
, .removeClass()
and toggleClass()
, which makes it easier if there is any logic which determines which classes should be added or removed, as you don't need to mess around with the space-delimited strings.
$("div").removeClass(["class1", "class2"]);
SQL ad hoc query abilities are enough of a reason for me. With a good schema and indexing on the tables, this is fast and effective and will have good performance.
select 1 from table
is used by some databases as a query to test a connection to see if it's alive, often used when retrieving or returning a connection to / from a connection pool.

I needed to use element.attr('form')
instead of element.form
.
I use Firefox on Fedora 12.
Try SilentCMD. This is a small freeware program that executes a batch file without displaying the command prompt window.
If the goal simply is to list all computer objects with an empty description attribute try this
import-module activedirectory
$domain = "domain.example.com"
Get-ADComputer -Filter '*' -Properties Description | where { $_.Description -eq $null }
It doesn't work as you expect because strip is character based. You need to do this instead:
foo = foo.replace(' ', '')[:-3].upper()
In addition to the correct answer by mdma, you can also use the mail command as follows:
mail [email protected] -s"Subject Here" -a"Content-Type: text/html; charset=\"us-ascii\""
you will get what you're looking for. Don't forget to put <HTML>
and </HTML>
in the email. Here's a quick script I use to email a daily report in HTML:
#!/bin/sh
(cat /path/to/tomorrow.txt mysql -h mysqlserver -u user -pPassword Database -H -e "select statement;" echo "</HTML>") | mail [email protected] -s"Tomorrow's orders as of now" -a"Content-Type: text/html; charset=\"us-ascii\""
UPDATE [TableName]
SET [ColumnName] = Replace([ColumnName], '[StringToRemove]', '[Replacement]')
In your instance it would be
UPDATE [TableName]
SET [ColumnName] = Replace([ColumnName], '[StringToRemove]', '')
Because there is no replacement (you want to get rid of it).
This will run on every row of the specified table. No need for a WHERE clause unless you want to specify only certain rows.
Try this....
get File from a content uri
fun fileFromContentUri(context: Context, contentUri: Uri): File {
// Preparing Temp file name
val fileExtension = getFileExtension(context, contentUri)
val fileName = "temp_file" + if (fileExtension != null) ".$fileExtension" else ""
// Creating Temp file
val tempFile = File(context.cacheDir, fileName)
tempFile.createNewFile()
try {
val oStream = FileOutputStream(tempFile)
val inputStream = context.contentResolver.openInputStream(contentUri)
inputStream?.let {
copy(inputStream, oStream)
}
oStream.flush()
} catch (e: Exception) {
e.printStackTrace()
}
return tempFile
}
private fun getFileExtension(context: Context, uri: Uri): String? {
val fileType: String? = context.contentResolver.getType(uri)
return MimeTypeMap.getSingleton().getExtensionFromMimeType(fileType)
}
@Throws(IOException::class)
private fun copy(source: InputStream, target: OutputStream) {

}
Add the following aliases. I think these should be made available in PowerShell by default:
function not-exist { -not (Test-Path $args) }
Set-Alias !exist not-exist -Option "Constant, AllScope"
Set-Alias exist Test-Path -Option "Constant, AllScope"
With that, the conditional statements will change to:
if (exist $path) { ... }
and
if (not-exist $path) { ... }
if (!exist $path) { ... }
If you really want it to look more semantic like having the <body>
in the middle you can use the <main>
element. With all the recent advances the <body>
element is not as semantic as it once was but you just have to think of it as a wrapper in which the view port sees.
<html>
<head>
</head>
<body>
<header>
</header>
<main>
<section></section>
<article></article>
</main>
<footer>
</footer>
<body>
</html>
I had the same problem.
Solved by sharing internet connection (on the hosting OS).
Network Connection Properties -> advanced -> Allow other users to connect...
As of PowerShell 2, simple:
$recipients = $addresses -split "; "
Note that the right hand side is actually a case-insensitive regular expression, not a simple match. Use csplit
to force case-sensitivity. See about_Split for more details.
Using simple autofocus
HTML5 attribute works for 'on load' scenario
<input autofocus placeholder="enter text" [(ngModel)]="test">
or
<button autofocus (click)="submit()">Submit</button>
As an alternate you can use reactive forms. Here is an example: https://stackblitz.com/edit/angular-pqb2xx
Template
<form [formGroup]="mainForm" ng-submit="submitForm()">
Global Price: <input type="number" formControlName="globalPrice">
<button type="button" [disabled]="mainForm.get('globalPrice').value === null" (click)="applyPriceToAll()">Apply to all</button>
<table border formArrayName="orderLines">
<ng-container *ngFor="let orderLine of orderLines let i=index" [formGroupName]="i">
<tr>
<td>{{orderLine.time | date}}</td>
<td>{{orderLine.quantity}}</td>
<td><input formControlName="price" type="number"></td>
</tr>
</ng-container>
</table>
</form>

I really like grep() and grepl() for this purpose.
grep() returns a vector of integers, which indicate where matches are.
yo <- c("a", "a", "b", "b", "c", "c")
grep("b", yo)
[1] 3 4
grepl() returns a logical vector, with "TRUE" at the location of matches.
yo <- c("a", "a", "b", "b", "c", "c")
grepl("b", yo)
[1] FALSE FALSE TRUE TRUE FALSE FALSE
These functions are case-sensitive.
I know is a bit later to reply, sorry. But that works for me.
export K8S_public_load_balancer_url="$(kubectl get services -n ${TENANT}-production -o wide | grep "ingress-nginx-internal$" | awk '{print $4}')"
And now I am able to fetch and pass the content of the variable to jq
export TF_VAR_public_load_balancer_url="$(aws elbv2 describe-load-balancers --region eu-west-1 | jq -r '.LoadBalancers[] | select (.DNSName == "'$K8S_public_load_balancer_url'") | .LoadBalancerArn')"
In my case I needed to use double quote and quote to access the variable value.
Cheers.
The Thread
class is used for creating and manipulating a thread in Windows.
A Task
represents some asynchronous operation and is part of the Task Parallel Library, a set of APIs for running tasks asynchronously and in parallel.
In the days of old (i.e. before TPL) it used to be that using the Thread
class was one of the standard ways to run code in the background or in parallel (a better alternative was often to use a ThreadPool
), however this was cumbersome and had several disadvantages, not least of which was the performance overhead of creating a whole new thread to perform a task in the background.
Nowadays using tasks and the TPL is a far better solution 90% of the time as it provides abstractions which allows far more efficient use of system resources. I imagine there are a few scenarios where you want explicit control over the thread on which you are running your code, however generally speaking if you want to run something asynchronously your first port of call should be the TPL.
Just to help if anyone stumble on this question like me, if you want to use if in PostgreSQL, you use "CASE"
select
case
when stage = 1 then 'running'
when stage = 2 then 'done'
when stage = 3 then 'stopped'
else
'not running'
end as run_status from processes
From the Active Record docs:
$this->db->where_in();
Generates a WHERE field IN ('item', 'item') SQL query joined with AND if appropriate
$names = array('Frank', 'Todd', 'James');
$this->db->where_in('username', $names);
// Produces: WHERE username IN ('Frank', 'Todd', 'James')
No.
The JSON is data only, and if you include a comment, then it will be data too.
You could have a designated data element called "_comment"
(or something) that should be ignored by apps that use the JSON data.
You would probably be better having the comment in the processes that generates/receives the JSON, as they are supposed to know what the JSON data will be in advance, or at least the structure of it.
But if you decided to:
{
"_comment": "comment text goes here...",
"glossary": {
"title": "example glossary",
"GlossDiv": {
"title": "S",
"GlossList": {
"GlossEntry": {
"ID": "SGML",
"SortAs": "SGML",
"GlossTerm": "Standard Generalized Markup Language",
"Acronym": "SGML",
"Abbrev": "ISO 8879:1986",
"GlossDef": {
"para": "A meta-markup language, used to create markup languages such as DocBook.",
"GlossSeeAlso": ["GML", "XML"]
},
"GlossSee": "markup"
}
}
}
}
}
You can use getEventListeners in your Google Chrome developer console.
getEventListeners(object) returns the event listeners registered on the specified object.
getEventListeners(document.querySelector('option[value=Closed]'));
This problem is beacouse your proyect is named serial.py and the library imported is name serial too , change the name and thats all.
Here's how to hook this up on any click (useful if your page is placing many AJAX calls and you're trying to navigate away).
$ ->
$.xhrPool = [];
$(document).ajaxSend (e, jqXHR, options) ->
$.xhrPool.push(jqXHR)
$(document).ajaxComplete (e, jqXHR, options) ->
$.xhrPool = $.grep($.xhrPool, (x) -> return x != jqXHR);
$(document).delegate 'a', 'click', ->
while (request = $.xhrPool.pop())
request.abort()
I don't think you need a case statement. You just need to update your where clause and make sure you have correct parentheses to group the clauses.
SELECT Sum(CAMount) as PaymentAmount
from TableOrderPayment
where (CStatus = 'Active' AND CPaymentType = 'Cash')
OR (CStatus = 'Active' and CPaymentType = 'Check' and CDate<=SYSDATETIME())
The answers posted before mine assume that CDate<=SYSDATETIME() is also appropriate for Cash payment type as well. I think I split mine out so it only looks for that clause for check payments.
1)
var merged = {};
for(key in obj1)
merged[key] = obj1[key];
for(key in obj2)
merged[key] = obj2[key];
2)
var merged = {};
Object.keys(obj1).forEach(k => merged[k] = obj1[k]);
Object.keys(obj2).forEach(k => merged[k] = obj2[k]);
Object.keys(obj1)
.concat(Object.keys(obj2))
.forEach(k => merged[k] = k in obj2 ? obj2[k] : obj1[k]);
3) Simplest way:
var merged = {};
Object.assign(merged, obj1, obj2);
The answer for the last two can also be deducted from the golden rule in C:
Declaration follows use.
int (*arr2)[8];
What happens if you dereference arr2
? You get an array of 8 integers.
int *(arr3[8]);
What happens if you take an element from arr3
? You get a pointer to an integer.
This also helps when dealing with pointers to functions. To take sigjuice's example:
float *(*x)(void )
What happens when you dereference x
? You get a function that you can call with no arguments. What happens when you call it? It will return a pointer to a float
.
Operator precedence is always tricky, though. However, using parentheses can actually also be confusing because declaration follows use. At least, to me, intuitively arr2
looks like an array of 8 pointers to ints, but it is actually the other way around. Just takes some getting used to. Reason enough to always add a comment to these declarations, if you ask me :)
edit: example
By the way, I just stumbled across the following situation: a function that has a static matrix and that uses pointer arithmetic to see if the row pointer is out of bounds. Example:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define NUM_ELEM(ar) (sizeof(ar) / sizeof((ar)[0]))
int *
put_off(const int newrow[2])
{
static int mymatrix[3][2];
static int (*rowp)[2] = mymatrix;
int (* const border)[] = mymatrix + NUM_ELEM(mymatrix);
memcpy(rowp, newrow, sizeof(*rowp));
rowp += 1;
if (rowp == border) {
rowp = mymatrix;
}
return *rowp;
}
int
main(int argc, char *argv[])
{
int i = 0;
int row[2] = {0, 1};
int *rout;
for (i = 0; i < 6; i++) {
row[0] = i;
row[1] += i;
rout = put_off(row);
printf("%d (%p): [%d, %d]\n", i, (void *) rout, rout[0], rout[1]);
}
return 0;
}
Output:
0 (0x804a02c): [0, 0]
1 (0x804a034): [0, 0]
2 (0x804a024): [0, 1]
3 (0x804a02c): [1, 2]
4 (0x804a034): [2, 4]
5 (0x804a024): [3, 7]
Note that the value of border never changes, so the compiler can optimize that away. This is different from what you might initially want to use: const int (*border)[3]
: that declares border as a pointer to an array of 3 integers that will not change value as long as the variable exists. However, that pointer may be pointed to any other such array at any time. We want that kind of behaviour for the argument, instead (because this function does not change any of those integers). Declaration follows use.
(p.s.: feel free to improve this sample!)

Simple example...
Let's say the child view controller has a UISlider
and we want to pass the value of the slider back to the parent via a delegate.
In the child view controller's header file, declare the delegate type and its methods:
ChildViewController.h
#import <UIKit/UIKit.h>
// 1. Forward declaration of ChildViewControllerDelegate - this just declares
// that a ChildViewControllerDelegate type exists so that we can use it
// later.
@protocol ChildViewControllerDelegate;
// 2. Declaration of the view controller class, as usual
@interface ChildViewController : UIViewController
// Delegate properties should always be weak references
// See http://stackoverflow.com/a/4796131/263871 for the rationale
// (Tip: If you're not using ARC, use `assign` instead of `weak`)
@property (nonatomic, weak) id<ChildViewControllerDelegate> delegate;
// A simple IBAction method that I'll associate with a close button in
// the UI. We'll call the delegate's childViewController:didChooseValue:
// method inside this handler.
- (IBAction)handleCloseButton:(id)sender;
@end
// 3. Definition of the delegate's interface
@protocol ChildViewControllerDelegate <NSObject>
- (void)childViewController:(ChildViewController*)viewController
didChooseValue:(CGFloat)value;
@end
In the child view controller's implementation, call the delegate methods as required.
ChildViewController.m
#import "ChildViewController.h"
@implementation ChildViewController
- (void)handleCloseButton:(id)sender {
// Xcode will complain if we access a weak property more than
// once here, since it could in theory be nilled between accesses
// leading to unpredictable results. So we'll start by taking
// a local, strong reference to the delegate.
id<ChildViewControllerDelegate> strongDelegate = self.delegate;
// Our delegate method is optional, so we should
// check that the delegate implements it
if ([strongDelegate respondsToSelector:@selector(childViewController:didChooseValue:)]) {
[strongDelegate childViewController:self didChooseValue:self.slider.value];
}
}
@end
In the parent view controller's header file, declare that it implements the ChildViewControllerDelegate
protocol.
RootViewController.h
#import <UIKit/UIKit.h>
#import "ChildViewController.h"
@interface RootViewController : UITableViewController <ChildViewControllerDelegate>
@end
In the parent view controller's implementation, implement the delegate methods appropriately.
RootViewController.m
#import "RootViewController.h"
@implementation RootViewController
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
ChildViewController *detailViewController = [[ChildViewController alloc] init];
// Assign self as the delegate for the child view controller
detailViewController.delegate = self;
[self.navigationController pushViewController:detailViewController animated:YES];
}
// Implement the delegate methods for ChildViewControllerDelegate
- (void)childViewController:(ChildViewController *)viewController didChooseValue:(CGFloat)value {
// Do something with value...
// ...then dismiss the child view controller
[self.navigationController popViewControllerAnimated:YES];
}
@end
Hope this helps!

I suggest using RegExp .test()
function to check for a pattern match, and the only thing you need to change is remove the start/end of line anchors (and the *
quantifier is also redundant) in the regex:
var format = /[ `!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/;_x000D_
// ^ ^ _x000D_
document.write(format.test("My@string-with(some%text)") + "<br/>");_x000D_
document.write(format.test("My string with spaces") + "<br/>");_x000D_
document.write(format.test("MyStringContainingNoSpecialChars"));
_x000D_
The anchors (like ^
start of string/line, $
end od string/line and \b
word boundaries) can restrict matches at specific places in a string. When using ^
the regex engine checks if the next subpattern appears right at the start of the string (or line if /m
modifier is declared in the regex). Same case with $
: the preceding subpattern should match right at the end of the string.
In your case, you want to check the existence of the special character from the set anywhere in the string. Even if it is only one, you want to return false
. Thus, you should remove the anchors, and the quantifier *
. The *
quantifier would match even an empty string, thus we must remove it in order to actually check for the presence of at least 1 special character (actually, without any quantifiers we check for exactly one occurrence, same as if we were using {1}
limiting quantifier).

git rev-list --max-parents=0 HEAD
(from tiho's comment. As Chris Johnsen notices, --max-parents
was introduced after this answer was posted.)
Technically, there may be more than one root commit. This happens when multiple previously independent histories are merged together. It is common when a project is integrated via a subtree merge.
The git.git
repository has six root commits in its history graph (one each for Linus’s initial commit, gitk, some initially separate tools, git-gui, gitweb, and git-p4). In this case, we know that e83c516
is the one we are probably interested in. It is both the earliest commit and a root commit.
It is not so simple in the general case.
Imagine that libfoo has been in development for a while and keeps its history in a Git repository (libfoo.git
). Independently, the “bar” project has also been under development (in bar.git
), but not for as long libfoo (the commit with the earliest date in libfoo.git
has a date that precedes the commit with the earliest date in bar.git
). At some point the developers of “bar” decide to incorporate libfoo into their project by using a subtree merge. Prior to this merge it might have been trivial to determine the “first” commit in bar.git
(there was probably only one root commit). After the merge, however, there are multiple root commits and the earliest root commit actually comes from the history of libfoo, not “bar”.
You can find all the root commits of the history DAG like this:
git rev-list --max-parents=0 HEAD
For the record, if --max-parents
weren't available, this does also work:
git rev-list --parents HEAD | egrep "^[a-f0-9]{40}$"
If you have useful tags in place, then git name-rev
might give you a quick overview of the history:
git rev-list --parents HEAD | egrep "^[a-f0-9]{40}$" | git name-rev --stdin
Use this often? Hard to remember? Add a git alias for quick access
git config --global alias.first "rev-list --max-parents=0 HEAD"
Now you can simply do
git first
Simple way of solving this issue is save the both entity. first save the child entity and then save the parent entity. Because parent entity is depend on child entity for the foreign key value.
Below simple exam of one to one relationship
insert into Department (name, numOfemp, Depno) values (?, ?, ?)
Hibernate: insert into Employee (SSN, dep_Depno, firstName, lastName, middleName, empno) values (?, ?, ?, ?, ?, ?)
Session session=sf.openSession();
session.beginTransaction();
session.save(dep);
session.save(emp);
Try this example
Html
<div class="testimonial" data-index="1">
Testimonial 1
</div>
<div class="testimonial" data-index="2">
Testimonial 2
</div>
<div class="testimonial" data-index="3">
Testimonial 3
</div>
<div class="testimonial" data-index="4">
Testimonial 4
</div>
<div class="testimonial" data-index="5">
Testimonial 5
</div>
When we want to access those divs
which has data-index
greater than 2
then we need this jquery.
$('div[class="testimonial"]').each(function(index,item){
if(parseInt($(item).data('index'))>2){
$(item).html('Testimonial '+(index+1)+' by each loop');
}
});
You could spare yourself the transformations, you could use CSS3 Transitions to flip <div>
's and <ol>
's and any HTML tag you want. Here are some demos with source code explain to see and learn: http://www.webdesignerwall.com/trends/47-amazing-css3-animation-demos/
I had problems, if the file contained German Umlauts (ä,ö,ü). I could solve the problem by using:
ec = Encoding::Converter.new('iso-8859-1', 'utf-8')
...
f << ec.convert(seg)

For people using AWS, the COMMENT ON EXTENSION
is possible only as superuser, and as we know by the docs, RDS instances are managed by Amazon. As such, to prevent you from breaking things like replication, your users - even the root user you set up when you create the instance - will not have full superuser privileges:
http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Appendix.PostgreSQL.CommonDBATasks.html
When you create a DB instance, the master user system account that you create is assigned to the rds_superuser role. The rds_superuser role is a pre-defined Amazon RDS role similar to the PostgreSQL superuser role (customarily named postgres in local instances), but with some restrictions. As with the PostgreSQL superuser role, the rds_superuser role has the most privileges on your DB instance and you should not assign this role to users unless they need the most access to the DB instance.
In order to fix this error, just use --
to comment out the lines of SQL that contains COMMENT ON EXTENSION
You can try with:
{% if theList.object_list.count > 0 %}
blah, blah...
{% else %}
blah, blah....
{% endif %}
If you're on the Model Overview page you get a tab with the schema. If you rightclick on that tab you get an option to "edit schema". From there you can rename the schema by adding a new name, then click outside the field. This goes for MySQL Workbench 5.2.30 CE
Edit: On the model overview it's under Physical Schemata

Use IEquatable<T>
Interface which has a method Equals
.
You can also use "bold" and "italic" instead of "normal" here. "Verdana" can be used for fontname..
But another question is this: How do you set the color of the text You write?
Answer: You use the turtle.color() method or turtle.fillcolor(), like this:
turtle.fillcolor("blue")
or just:
turtle.color("orange")
These calls must come before the turtle.write() command..

You JSON doesn't match your struct fields: E.g. "district" in JSON and "District" as the field.
Also: Your Item is a slice type but your JSON is a dict value. Do not mix this up. Slices decode from arrays.
Char
has a fixed length (supports 2000 characters), it is stand for character is a data type
Varchar
has a variable length (supports 4000 characters)
The following example uses the GroupBy method to return objects that are grouped by PersonID
.
var results = persons.GroupBy(x => x.PersonID)
.Select(x => (PersonID: x.Key, Cars: x.Select(p => p.car).ToList())
).ToList();
Or
var results = persons.GroupBy(
person => person.PersonID,
(key, groupPerson) => (PersonID: key, Cars: groupPerson.Select(x => x.car).ToList()));
Or
var results = from person in persons
group person by person.PersonID into groupPerson
select (PersonID: groupPerson.Key, Cars: groupPerson.Select(x => x.car).ToList());
Or you can use ToLookup
, Basically ToLookup
uses EqualityComparer<TKey>
.Default to compare keys and do what you should do manually when using group by and to dictionary.
i think it's excuted inmemory
ILookup<int, string> results = persons.ToLookup(
person => person.PersonID,
person => person.car);
File -> Export -> Web -> WAR file
OR in Kepler follow as shown below :
After you correct the possible dmp file problem, this is a way to ensure that the schema is remapped and imported appropriately. This will also ensure that the tablespace will change also, if needed:
impdp system/<password> SCHEMAS=user1 remap_schema=user1:user2 \
remap_tablespace=user1:user2 directory=EXPORTDIR \
dumpfile=user1.dmp logfile=E:\Data\user1.log
EXPORTDIR must be defined in oracle as a directory as the system user
create or replace directory EXPORTDIR as 'E:\Data';
grant read, write on directory EXPORTDIR to user2;
If you want to create a garage and fill it up with new cars that can be accessed later, use this code:
for (int i = 0; i < garage.length; i++)
garage[i] = new Car("argument");
Also, the cars are later accessed using:
garage[0];
garage[1];
garage[2];
etc.
As much as people like to say "order doesn't matter its just convention" this breaks down when entering cross domain interfaces, IE transfer from C ordering to Fortran ordering or some other ordering scheme. There, precisely how your data is layed out and how shape is represented in numpy is very important.
By default, numpy uses C ordering, which means contiguous elements in memory are the elements stored in rows. You can also do FORTRAN ordering ("F"), this instead orders elements based on columns, indexing contiguous elements.
Numpy's shape further has its own order in which it displays the shape. In numpy, shape is largest stride first, ie, in a 3d vector, it would be the least contiguous dimension, Z, or pages, 3rd dim etc... So when executing:
np.zeros((2,3,4)).shape
you will get
(2,3,4)
which is actually (frames, rows, columns)
. doing np.zeros((2,2,3,4)).shape
instead would mean (metaframs, frames, rows, columns)
. This makes more sense when you think of creating multidimensional arrays in C like langauges. For C++, creating a non contiguously defined 4D array results in an array [ of arrays [ of arrays [ of elements ]]]
. This forces you to de reference the first array that holds all the other arrays (4th dimension) then the same all the way down (3rd, 2nd, 1st) resulting in syntax like:
double element = array4d[w][z][y][x]
;
In fortran, this indexed ordering is reversed (x is instead first array4d[x][y][z][w]
), most contiguous to least contiguous and in matlab, it gets all weird.
Matlab tried to preserve both mathematical default ordering (row, column) but also use column major internally for libraries, and not follow C convention of dimensional ordering. In matlab, you order this way:
double element = array4d[y][x][z][w]
;
which deifies all convention and creates weird situations where you are sometimes indexing as if row ordered and sometimes column ordered (such as with matrix creation).
In reality, Matlab is the unintuitive one, not Numpy.
it is called Identity Columns
and it is available only from oracle Oracle 12c
CREATE TABLE identity_test_tab
(
id NUMBER GENERATED ALWAYS AS IDENTITY,
description VARCHAR2 (30)
);
example of insert into Identity Columns
as below
INSERT INTO identity_test_tab (description) VALUES ('Just DESCRIPTION');
1 row created.
you can NOT do insert like below
INSERT INTO identity_test_tab (id, description) VALUES (NULL, 'ID=NULL and DESCRIPTION');
ERROR at line 1: ORA-32795: cannot insert into a generated always identity column
INSERT INTO identity_test_tab (id, description) VALUES (999, 'ID=999 and DESCRIPTION');
ERROR at line 1: ORA-32795: cannot insert into a generated always identity column
You should use this:
"\n"
You also might wanna have a look at PHP EOL.
So here is how you will do it.
Write a javascript function which fires whenever the window is resized.
window.onresize = function(event) {
var height=$(window).height();
var width=$(window).width();
$.ajax({
url: "/getwindowsize.ashx",
type: "POST",
data : { Height: height,
Width:width,
selectedValue:selectedValue },
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
// do stuff
}
}
Codebehind of Handler:
public class getwindowsize : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "application/json";
string Height = context.Request.QueryString["Height"];
string Width = context.Request.QueryString["Width"];
}
This might be another solution for those with the latest Windows 10 creator version:

You can use a similar construct by using the sys.columns
table io sys.objects
.
IF NOT EXISTS (
SELECT *
FROM sys.columns
WHERE object_id = OBJECT_ID(N'[dbo].[Person]')
AND name = 'ColumnName'
)
response_json = ("{ \"response_json\":" + str(list_of_dict)+ "}").replace("\'","\"")
response_json = json.dumps(response_json)
response_json = json.loads(response_json)

Lots of ways.
Use ADO.Net and use fill on the data adapter to get a DataTable:
using (SqlDataAdapter dataAdapter
= new SqlDataAdapter ("SELECT blah FROM blahblah ", sqlConn))
{
// create the DataSet
DataSet dataSet = new DataSet();
// fill the DataSet using our DataAdapter
dataAdapter.Fill (dataSet);
}
You can then get the data table out of the dataset.
Note in the upvoted answer dataset isn't used, (It appeared after my answer) It does
// create data adapter
SqlDataAdapter da = new SqlDataAdapter(cmd);
// this will query your database and return the result to your datatable
da.Fill(dataTable);
Which is preferable to mine.
I would strongly recommend looking at entity framework though ... using datatables and datasets isn't a great idea. There is no type safety on them which means debugging can only be done at run time. With strongly typed collections (that you can get from using LINQ2SQL or entity framework) your life will be a lot easier.
Edit: Perhaps I wasn't clear: Datatables = good, datasets = evil. If you are using ADO.Net then you can use both of these technologies (EF, linq2sql, dapper, nhibernate, orm of the month) as they generally sit on top of ado.net. The advantage you get is that you can update your model far easier as your schema changes provided you have the right level of abstraction by levering code generation.
The ado.net adapter uses providers that expose the type info of the database, for instance by default it uses a sql server provider, you can also plug in - for instance - devart postgress provider and still get access to the type info which will then allow you to as above use your orm of choice (almost painlessly - there are a few quirks) - i believe Microsoft also provide an oracle provider. The ENTIRE purpose of this is to abstract away from the database implementation where possible.
