I ran into the 'Expecting: ANY PRIVATE KEY' error when using openssl on Windows (Ubuntu Bash and Git Bash had the same issue).

The cause of the problem was that I'd saved the key and certificate files in Notepad using UTF8. Resaving both files in ANSI format solved the problem.

To do this task download.js library can be used. Here is an example from library docs:

download("data:image/gif;base64,R0lGODlhRgAVAIcAAOfn5+/v7/f39////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////yH5BAAAAP8ALAAAAABGABUAAAj/AAEIHAgggMGDCAkSRMgwgEKBDRM+LBjRoEKDAjJq1GhxIMaNGzt6DAAypMORJTmeLKhxgMuXKiGSzPgSZsaVMwXUdBmTYsudKjHuBCoAIc2hMBnqRMqz6MGjTJ0KZcrz5EyqA276xJrVKlSkWqdGLQpxKVWyW8+iJcl1LVu1XttafTs2Lla3ZqNavAo37dm9X4eGFQtWKt+6T+8aDkxUqWKjeQUvfvw0MtHJcCtTJiwZsmLMiD9uplvY82jLNW9qzsy58WrWpDu/Lp0YNmPXrVMvRm3T6GneSX3bBt5VeOjDemfLFv1XOW7kncvKdZi7t/S7e2M3LkscLcvH3LF7HwSuVeZtjuPPe2d+GefPrD1RpnS6MGdJkebn4/+oMSAAOw==", "dlDataUrlBin.gif", "image/gif");

The following code will help you to get the element of the mouse pointer. The resulted elements will display in the console.

document.addEventListener('mousemove', function(e) {
    console.log(document.elementFromPoint(e.pageX, e.pageY)); 
})

base64 encode/decode example:

import base64

mystr = 'O João mordeu o cão!'

# Encode
mystr_encoded = base64.b64encode(mystr.encode('utf-8'))
# b'TyBKb8OjbyBtb3JkZXUgbyBjw6NvIQ=='

# Decode
mystr_encoded = base64.b64decode(mystr_encoded).decode('utf-8')
# 'O João mordeu o cão!'

My IDE is NetBeans. I put log4j.property file as shown in the pictures

Root

Web

WEB-INF

To use this property file you should to write this code:

package example;

import java.io.File;
import org.apache.log4j.PropertyConfigurator;
import org.apache.log4j.Logger;
import javax.servlet.*;
public class test {

public static ServletContext context;
static Logger log = Logger.getLogger("example/test");

public test() {

        String homeDir = context.getRealPath("/");
        File propertiesFile = new File(homeDir, "WEB-INF/log4j.properties");
        PropertyConfigurator.configure(propertiesFile.toString());
        log.info("This is a test");
    }
}

You can define static ServletContext context from another JSP file. Example:

test.context = getServletContext(); 
test sample = new test(); 

Now you can use log4j.property file in your projects.

You can embed HTML in Markdown, so you can do something like this:

<img style="float: right;" src="whatever.jpg">

Continue markdown text...

:%s/^/vendor_/

or am I missing something?

Try this,

string Date = datePicker1.SelectedDate.Value.ToString("dd-MMM-yyyy");

It worked for me the output format will be '02-May-2016'

The enum based singleton

a modern look at an old problem

This approach implements the singleton by taking advantage of Java's guarantee that any enum value is instantiated only once in a Java program and enum provides implicit support for thread safety. Since Java enum values are globally accessible, so it can be used as the singleton.

public enum Singleton {
    SINGLETON; 
    public void method() { }
}

How does this work? Well, the line two of the code may be considered to something like this:

public final static Singleton SINGLETON = new Singleton(); 

And we get good old early initialized singleton.

Remember that since this is an enum you can always access to instance via Singleton.SINGLETON as well:

Singleton s = Singleton.SINGLETON;

• To prevent creating another instances of singleton during deserialization use enum based singleton because serialization of enum is taken care by JVM. Enum serialization and deserialization work differently than for normal java objects. The only thing that gets serialized is the name of the enum value. During the deserialization process the enum valueOf method is used with the deserialized name to get the desired instance.
• Enum based singleton allows to protect itself from reflection attack. The enum type actually extends the java Enum class. The reason that reflection cannot be used to instantiate objects of enum type is because the java specification disallows and that rule is coded in the implementation of the newInstance method of the Constructor class, which is usually used for creating objects via reflection:

if ((clazz.getModifiers() & Modifier.ENUM) != 0)
    throw new IllegalArgumentException("Cannot reflectively create enum objects");

• Enum is not supposed to be cloned because there must be exactly one instance of each value.
• The most laconic code among all singleton realization.

• The enum based singleton does not allow lazy initialization.
• If you changed your design and wanted to convert your singleton to multiton, enum would not allow this. The multiton pattern is used for the controlled creation of multiple instances, which it manages through the use of a map. Rather than having a single instance per application (e.g. the java.lang.Runtime) the multiton pattern instead ensures a single instance per key.
• Enum appears only in Java 5 so you can not use it in prior version.

There are several realization of singleton pattern each one with advantages and disadvantages.

• Eager loading singleton
• Double-checked locking singleton
• Initialization-on-demand holder idiom
• The enum based singleton

Detailed description each of them is too verbose so I just put a link to a good article - All you want to know about Singleton

In the “Subclass of” field, select UITableViewController.

The class title changes to xxxxTableViewController. Leave that as is.

Make sure the “Also create XIB file” option is selected.

public static class ErrorCode
{
    public const IDictionary<string , string > m_ErrorCodeDic;

    public static ErrorCode()
    {
      m_ErrorCodeDic = new Dictionary<string, string>()
             { {"1","User name or password problem"} };             
    }
}

Probably initialise in the constructor.

Quote, which summarizes from this article:

1. SET is the ANSI standard for variable assignment, SELECT is not.
2. SET can only assign one variable at a time, SELECT can make multiple assignments at once.
3. If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
4. When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from its previous value)
5. As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.

It doesn't make a lot of sense, the original GAC was already quite capable of storing different versions of assemblies. And there's little reason to assume a program will ever accidentally reference the wrong assembly, all the .NET 4 assemblies got the [AssemblyVersion] bumped up to 4.0.0.0. The new in-process side-by-side feature should not change this.

My guess: there were already too many .NET projects out there that broke the "never reference anything in the GAC directly" rule. I've seen it done on this site several times.

Only one way to avoid breaking those projects: move the GAC. Back-compat is sacred at Microsoft.

A very common mistake is as follows. You have one view, UIView* a, and another one, UIView* b. You add b to a as a subview. If you try to call viewWillAppear in b, it will never be fired, because it is a subview of a

Just create a new field to bypass this security thing:

var $oldPassword = $("#password");
var $newPassword = $("<input type='text' />")
                          .val($oldPassword.val())
                          .appendTo($oldPassword.parent());
$oldPassword.remove();
$newPassword.attr('id','password');

There should be

$('.send_upload')

but not $('.upload')

Though linkedHashMap doesn't provide any method to get first, last or any specific object.

But its pretty trivial to get :

Map<Integer,String> orderMap = new LinkedHashMap<Integer,String>();  
Set<Integer> al =   orderMap.keySet();

now using iterator on al object ; you can get any object.

You can use the ES6 Destructuring Assignment feature with a rest operator. A comma indicates where you want to remove the element and the rest (...arr) operator to give you the remaining elements of the array.

const source = [1,2,3,5,6];_x000D_
_x000D_
function removeFirst(list) {_x000D_
   var  [, ...arr] = list;_x000D_
   return arr;_x000D_
}_x000D_
const arr = removeFirst(source);_x000D_
console.log(arr); // [2, 3, 5, 6]_x000D_
console.log(source); // [1, 2, 3, 5, 6]

If you are working on .NET 4.5 project in VS 2012 (or newer), you can just Special Paste your XML file as classes.

1. Copy your XML file's content to clipboard
2. In editor, select place where you want your classes to be pasted
3. From the menu, select EDIT > Paste Special > Paste XML As Classes

krosenvold's answer inspired the following script which does the following:

• get the dd dump via ssh from a remote server (as gz file)
• unzip the dump
• convert it to vmware

the script is restartable and checks the existence of the intermediate files. It also uses pv and qemu-img -p to show the progress of each step.

In my environment 2 x Ubuntu 12.04 LTS the steps took:

• 3 hours to get a 47 GByte disk dump of a 60 GByte partition
• 20 minutes to unpack to a 60 GByte dd file
• 45 minutes to create the vmware file

How about this?

<ul>
<?php while ($items = array_pop($lists)) { ?>
    <ul>
    <?php foreach ($items as $item) { ?>
        <li><?= $item ?></li>
    <?php
    }//foreach
}//while ?>

We can still use the more widely-used braces and, at the same time, increase readability.

You can also do something much shorter:

SELECT FORMAT(2.3332232,'N2')

use a cursor

ADDENDUM: [MS SQL cursor example]

declare @field1 int
declare @field2 int
declare cur CURSOR LOCAL for
    select field1, field2 from sometable where someotherfield is null

open cur

fetch next from cur into @field1, @field2

while @@FETCH_STATUS = 0 BEGIN

    --execute your sproc on each row
    exec uspYourSproc @field1, @field2

    fetch next from cur into @field1, @field2
END

close cur
deallocate cur

in MS SQL, here's an example article

note that cursors are slower than set-based operations, but faster than manual while-loops; more details in this SO question

ADDENDUM 2: if you will be processing more than just a few records, pull them into a temp table first and run the cursor over the temp table; this will prevent SQL from escalating into table-locks and speed up operation

ADDENDUM 3: and of course, if you can inline whatever your stored procedure is doing to each user ID and run the whole thing as a single SQL update statement, that would be optimal

To wrap in single quotes (for example) ciw'<C-r>"'<esc> works, but repeat won't work. Try:

ciw'<C-r><C-o>"'<esc>

This puts the contents of the default register "literally". Now you can press . on any word to wrap it in quotes. To learn more see :h[elp] i_ctrl-r and more about text objects at :h text-objects

In Python 3.x, raw_input was renamed to input and the Python 2.x input was removed.

This means that, just like raw_input, input in Python 3.x always returns a string object.

To fix the problem, you need to explicitly make those inputs into integers by putting them in int:

x = int(input("Enter a number: "))
y = int(input("Enter a number: "))

I'd use the different methods based on how I wanted to reference the items.

Use foreach if you just want the current item.

Use for if you need an indexer to do relative comparisons. (I.e. how does this compare to the previous/next item?)

I have never noticed a performance difference. I'd wait until having a performance issue before worrying about it.

Here is a non-jQuery solution. Note you can't just use .click() as some browsers do not support it.

<script type="text/javascript">
function performClick(elemId) {
   var elem = document.getElementById(elemId);
   if(elem && document.createEvent) {
      var evt = document.createEvent("MouseEvents");
      evt.initEvent("click", true, false);
      elem.dispatchEvent(evt);
   }
}
</script>
<a href="#" onclick="performClick('theFile');">Open file dialog</a>
<input type="file" id="theFile" />

Beyond @Jaime excellent answer, another way to collapse a row is to uses a.strides[0] (assuming a is C-contiguous) which is equal to a.dtype.itemsize*a.shape[0]. Furthermore void(n) is a shortcut for dtype((void,n)). we arrive finally to this shortest version :

a[unique(a.view(void(a.strides[0])),1)[1]]

For

[[0 1 1 1 0 0]
 [1 1 1 0 0 0]
 [1 1 1 1 1 0]]

I'd avoid eval.

To solve this problem, you should know these things about JavaScript.

1. Functions are first-class objects, so they can be properties of an object (in which case they are called methods) or even elements of arrays.
2. If you aren't choosing the object a function belongs to, it belongs to the global scope. In the browser, that means you're hanging it on the object named "window," which is where globals live.
3. Arrays and objects are intimately related. (Rumor is they might even be the result of incest!) You can often substitute using a dot . rather than square brackets [], or vice versa.

Your problem is a result of considering the dot manner of reference rather than the square bracket manner.

So, why not something like,

window["functionName"]();

That's assuming your function lives in the global space. If you've namespaced, then:

myNameSpace["functionName"]();

Avoid eval, and avoid passing a string in to setTimeout and setInterval. I write a lot of JS, and I NEVER need eval. "Needing" eval comes from not knowing the language deeply enough. You need to learn about scoping, context, and syntax. If you're ever stuck with an eval, just ask--you'll learn quickly.

The rule is as following :

A B 

B as a descendant of A

A > B 

B as a child of A

So

div.dropdown *

and not

div.dropdown > *

Here's my example in which I work

I experienced the same issue on an import of a data dump. Temporarily disabling the innodb strict mode solved my problem.

-- shows the acutal value of the variable
SHOW VARIABLES WHERE variable_name = 'innodb_strict_mode';

-- change the value (ON/OFF)
SET GLOBAL innodb_strict_mode=ON;

I have found the answer to my question.

client.DefaultRequestHeaders.Add("X-Version","1");

That should add a custom header to your request

If you are trying to delete empty spaces , try using ='' instead of is null. Hence , if your row contains empty spaces , is null will not capture those records. Empty space is not null and null is not empty space.

Dec  Hex     Binary    Char-acter Description
0    00  00000000      NUL        null

32  20  00100000      Space       space

So I recommend:

delete  from foo_table  where bar = ''

#or 

delete  from foo_table  where bar = '' or bar is null 

#or even better , 

delete from foo_table where rtrim(ltrim(isnull(bar,'')))='';

As long as the web service methods and underlying exposed classes do not change, it's fairly trivial. With Visual Studio 2005 (and newer), adding a web reference creates an app.config (or web.config, for web apps) section that has this URL. All you have to do is edit the app.config file to reflect the desired URL.

In our project, our simple approach was to just have the app.config entries commented per environment type (development, testing, production). So we just uncomment the entry for the desired environment type. No special coding needed there.

Below are two methods that are superior to looping. Both handle a "no-find" case.

1. The VBA equivalent of a normal function VLOOKUP with error-handling if the variable doesn't exist (INDEX/MATCH may be a better route than VLOOKUP, ie if your two columns A and B were in reverse order, or were far apart)

2. VBAs FIND method (matching a whole string in column A given I use the xlWhole argument)

   Sub Method1()
   Dim strSearch As String
   Dim strOut As String
   Dim bFailed As Boolean
   
   strSearch = "trees"
   
   On Error Resume Next
   strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
   If Err.Number <> 0 Then bFailed = True
   On Error GoTo 0
   
   If Not bFailed Then
   MsgBox "corresponding value is " & vbNewLine & strOut
   Else
   MsgBox strSearch & " not found"
   End If
   End Sub
   
   Sub Method2()
       Dim rng1 As Range
       Dim strSearch As String
       strSearch = "trees"
       Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
       If Not rng1 Is Nothing Then
           MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
       Else
           MsgBox strSearch & " not found"
       End If
   End Sub
   

The problem is probably coming from the fact that Date is deprecated.

Consider using

java.util.Calendar

or

Joda-Time

Edit 2015:

Java 8 and later has built-in the new java.time package, which is similar to Joda-Time.

In your git dir, suppose you have sync all changes.

rm -rf .git 

rm -rf .gitmodules

Then do:

git init
git submodule add url_to_repo projectfolder

You can pass the inline handler the this keyword, obtaining the element which fired the event.

like,

onclick="confirmSubmit(this);"

What does shapiro.test do?

shapiro.test tests the Null hypothesis that "the samples come from a Normal distribution" against the alternative hypothesis "the samples do not come from a Normal distribution".

How to perform shapiro.test in R?

The R help page for ?shapiro.test gives,

x - a numeric vector of data values. Missing values are allowed, 
    but the number of non-missing values must be between 3 and 5000.

That is, shapiro.test expects a numeric vector as input, that corresponds to the sample you would like to test and it is the only input required. Since you've a data.frame, you'll have to pass the desired column as input to the function as follows:

> shapiro.test(heisenberg$HWWIchg)
#   Shapiro-Wilk normality test

# data:  heisenberg$HWWIchg 
# W = 0.9001, p-value = 0.2528

Interpreting results from shapiro.test:

First, I strongly suggest you read this excellent answer from Ian Fellows on testing for normality.

As shown above, the shapiro.test tests the NULL hypothesis that the samples came from a Normal distribution. This means that if your p-value <= 0.05, then you would reject the NULL hypothesis that the samples came from a Normal distribution. As Ian Fellows nicely put it, you are testing against the assumption of Normality". In other words (correct me if I am wrong), it would be much better if one tests the NULL hypothesis that the samples do not come from a Normal distribution. Why? Because, rejecting a NULL hypothesis is not the same as accepting the alternative hypothesis.

In case of the null hypothesis of shapiro.test, a p-value <= 0.05 would reject the null hypothesis that the samples come from normal distribution. To put it loosely, there is a rare chance that the samples came from a normal distribution. The side-effect of this hypothesis testing is that this rare chance happens very rarely. To illustrate, take for example:

set.seed(450)
x <- runif(50, min=2, max=4)
shapiro.test(x)
#   Shapiro-Wilk normality test
# data:  runif(50, min = 2, max = 4) 
# W = 0.9601, p-value = 0.08995

So, this (particular) sample runif(50, min=2, max=4) comes from a normal distribution according to this test. What I am trying to say is that, there are many many cases under which the "extreme" requirements (p < 0.05) are not satisfied which leads to acceptance of "NULL hypothesis" most of the times, which might be misleading.

Another issue I'd like to quote here from @PaulHiemstra from under comments about the effects on large sample size:

An additional issue with the Shapiro-Wilk's test is that when you feed it more data, the chances of the null hypothesis being rejected becomes larger. So what happens is that for large amounts of data even very small deviations from normality can be detected, leading to rejection of the null hypothesis event though for practical purposes the data is more than normal enough.

Although he also points out that R's data size limit protects this a bit:

Luckily shapiro.test protects the user from the above described effect by limiting the data size to 5000.

If the NULL hypothesis were the opposite, meaning, the samples do not come from a normal distribution, and you get a p-value < 0.05, then you conclude that it is very rare that these samples do not come from a normal distribution (reject the NULL hypothesis). That loosely translates to: It is highly likely that the samples are normally distributed (although some statisticians may not like this way of interpreting). I believe this is what Ian Fellows also tried to explain in his post. Please correct me if I've gotten something wrong!

@PaulHiemstra also comments about practical situations (example regression) when one comes across this problem of testing for normality:

In practice, if an analysis assumes normality, e.g. lm, I would not do this Shapiro-Wilk's test, but do the analysis and look at diagnostic plots of the outcome of the analysis to judge whether any assumptions of the analysis where violated too much. For linear regression using lm this is done by looking at some of the diagnostic plots you get using plot(lm()). Statistics is not a series of steps that cough up a few numbers (hey p < 0.05!) but requires a lot of experience and skill in judging how to analysis your data correctly.

Here, I find the reply from Ian Fellows to Ben Bolker's comment under the same question already linked above equally (if not more) informative:

For linear regression,

1. Don't worry much about normality. The CLT takes over quickly and if you have all but the smallest sample sizes and an even remotely reasonable looking histogram you are fine.

2. Worry about unequal variances (heteroskedasticity). I worry about this to the point of (almost) using HCCM tests by default. A scale location plot will give some idea of whether this is broken, but not always. Also, there is no a priori reason to assume equal variances in most cases.

3. Outliers. A cooks distance of > 1 is reasonable cause for concern.

Those are my thoughts (FWIW).

Hope this clears things up a bit.

What are -moz- and -webkit-?

CSS properties starting with -webkit-, -moz-, -ms- or -o- are called vendor prefixes.

Why do different browsers add different prefixes for the same effect?

A good explanation of vendor prefixes comes from Peter-Paul Koch of QuirksMode:

Originally, the point of vendor prefixes was to allow browser makers to start supporting experimental CSS declarations.

Let's say a W3C working group is discussing a grid declaration (which, incidentally, wouldn't be such a bad idea). Let's furthermore say that some people create a draft specification, but others disagree with some of the details. As we know, this process may take ages.

Let's furthermore say that Microsoft as an experiment decides to implement the proposed grid. At this point in time, Microsoft cannot be certain that the specification will not change. Therefore, instead of adding the grid to its CSS, it adds -ms-grid.

The vendor prefix kind of says "this is the Microsoft interpretation of an ongoing proposal." Thus, if the final definition of the grid is different, Microsoft can add a new CSS property grid without breaking pages that depend on -ms-grid.

UPDATE AS OF THE YEAR 2016

As this post 3 years old, it's important to mention that now most vendors do understand that these prefixes are just creating un-necessary duplicate code and that the situation where you need to specify 3 different CSS rules to get one effect working in all browser is an unwanted one.

As mentioned in this glossary about Mozilla's view on Vendor Prefix on May 3, 2016,

Browser vendors are now trying to get rid of vendor prefix for experimental features. They noticed that Web developers were using them on production Web sites, polluting the global space and making it more difficult for underdogs to perform well.

For example, just a few years ago, to set a rounded corner on a box you had to write:

-moz-border-radius: 10px 5px;
-webkit-border-top-left-radius: 10px;
-webkit-border-top-right-radius: 5px;
-webkit-border-bottom-right-radius: 10px;
-webkit-border-bottom-left-radius: 5px;
border-radius: 10px 5px;

But now that browsers have come to fully support this feature, you really only need the standardized version:

border-radius: 10px 5px;

Finding the right rules for all browsers

As still there's no standard for common CSS rules that work on all browsers, you can use tools like caniuse.com to check support of a rule across all major browsers.

You can also use pleeease.io/play. Pleeease is a Node.js application that easily processes your CSS. It simplifies the use of preprocessors and combines them with best postprocessors. It helps create clean stylesheets, support older browsers and offers better maintainability.

Input:

a {
  column-count: 3;
  column-gap: 10px;
  column-fill: auto;
}

Output:

a {
  -webkit-column-count: 3;
     -moz-column-count: 3;
          column-count: 3;
  -webkit-column-gap: 10px;
     -moz-column-gap: 10px;
          column-gap: 10px;
  -webkit-column-fill: auto;
     -moz-column-fill: auto;
          column-fill: auto;
}

If you are using (org.springframework.jdbc.datasource.DriverManagerDataSource) in ApplicationContext.xml to specify Database details then use below simple property to specify the schema.

<property name="schema" value="schemaName" />

According to eduLINQ:

The best way to get to grips with what GroupJoin does is to think of Join. There, the overall idea was that we looked through the "outer" input sequence, found all the matching items from the "inner" sequence (based on a key projection on each sequence) and then yielded pairs of matching elements. GroupJoin is similar, except that instead of yielding pairs of elements, it yields a single result for each "outer" item based on that item and the sequence of matching "inner" items.

The only difference is in return statement:

Join:

var lookup = inner.ToLookup(innerKeySelector, comparer); 
foreach (var outerElement in outer) 
{ 
    var key = outerKeySelector(outerElement); 
    foreach (var innerElement in lookup[key]) 
    { 
        yield return resultSelector(outerElement, innerElement); 
    } 
} 

GroupJoin:

var lookup = inner.ToLookup(innerKeySelector, comparer); 
foreach (var outerElement in outer) 
{ 
    var key = outerKeySelector(outerElement); 
    yield return resultSelector(outerElement, lookup[key]); 
}

In addition to the intuitive explanation Chris Smith has provided, we can consider why this is the case from a different perspective: considering undirected graphs.

To see why in a DIRECTED graph the answer is n*(n-1), consider an undirected graph (which simply means that if there is a link between two nodes (A and B) then you can go in both ways: from A to B and from B to A). The maximum number of edges in an undirected graph is n(n-1)/2 and obviously in a directed graph there are twice as many.

Good, you might ask, but why are there a maximum of n(n-1)/2 edges in an undirected graph? For that, Consider n points (nodes) and ask how many edges can one make from the first point. Obviously, n-1 edges. Now how many edges can one draw from the second point, given that you connected the first point? Since the first and the second point are already connected, there are n-2 edges that can be done. And so on. So the sum of all edges is:

Sum = (n-1)+(n-2)+(n-3)+...+3+2+1 

Since there are (n-1) terms in the Sum, and the average of Sum in such a series is ((n-1)+1)/2 {(last + first)/2}, Sum = n(n-1)/2

I was having the same problem, but using Long type. I changed for INT and it worked for me.

CREATE TABLE lists (
 id INT NOT NULL AUTO_INCREMENT,
 desc varchar(30),
 owner varchar(20),
 visibility boolean,
 PRIMARY KEY (id)
 );

For Mac users, see this answer:

Essentially, your OS may be blocking Intel from running what it needs to get your AVD going. Go into System Preferences -> Security and Privacy and you should see an option there to enable the Intel processes. Restart Android Studio and you should be good to go.

A good and simple example for nested try/except could be the following:

import numpy as np

def divide(x, y):
    try:
        out = x/y
    except:
        try:
            out = np.inf * x / abs(x)
        except:
            out = np.nan
    finally:
        return out

Now try various combinations and you will get the correct result:

divide(15, 3)
# 5.0

divide(15, 0)
# inf

divide(-15, 0)
# -inf

divide(0, 0)
# nan

(Of course, we have NumPy, so we don't need to create this function.)

I tried using this example but it failed miserably. Every time I use to invoke finish()/ finishactivity() inside a handler, I end up with this menacing java.lang.IllegalAccess Exception. i'm not sure how did it work for the one who posed the question.

Instead the solution I found was that create a method in your activity such as

void kill_activity()
{ 
    finish();
}

Invoke this method from inside the run method of the handler. This worked like a charm for me. Hope this helps anyone struggling with "how to close an activity from a different thread?".

You need to set the binding context of the ToolStripComboBox.ComboBox.

Here is a slightly modified version of the code that I have just recreated using Visual Studio. The menu item combo box is called toolStripComboBox1 in my case. Note the last line of code to set the binding context.

I noticed that if the combo is in the visible are of the toolstrip, the binding works without this but not when it is in a drop-down. Do you get the same problem?

If you can't get this working, drop me a line via my contact page and I will send you the project. You won't be able to load it using SharpDevelop but will with C# Express.

var languages = new string[2];
languages[0] = "English";
languages[1] = "German";

DataSet myDataSet = new DataSet();

// --- Preparation
DataTable lTable = new DataTable("Lang");
DataColumn lName = new DataColumn("Language", typeof(string));
lTable.Columns.Add(lName);

for (int i = 0; i < languages.Length; i++)
{
    DataRow lLang = lTable.NewRow();
    lLang["Language"] = languages[i];
    lTable.Rows.Add(lLang);
}
myDataSet.Tables.Add(lTable);

toolStripComboBox1.ComboBox.DataSource = myDataSet.Tables["Lang"].DefaultView;
toolStripComboBox1.ComboBox.DisplayMember = "Language";

toolStripComboBox1.ComboBox.BindingContext = this.BindingContext;

There is a solution to create file (on external cache dir or anywhere else) and put this file's uri as output extra to camera intent - this will define path where taken picture will be stored.

Here is an example:

File file;
Uri fileUri;
final int RC_TAKE_PHOTO = 1;

    private void takePhoto() {
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        file = new File(getActivity().getExternalCacheDir(), 
                String.valueOf(System.currentTimeMillis()) + ".jpg");
        fileUri = Uri.fromFile(file);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
        getActivity().startActivityForResult(intent, RC_TAKE_PHOTO);

    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RC_TAKE_PHOTO && resultCode == RESULT_OK) {

                //do whatever you need with taken photo using file or fileUri

            }
        }
    }

Then if you don't need the file anymore, you can delete it using file.delete();

By the way, files from cache dir will be removed when user clears app's cache from apps settings.

for (int i = 0; i < list.length; i++) {
   if (list.get(i) .getName().equalsIgnoreCase("myName")) {
    System.out.println(i);
    break;
  }
}

Schemas logically group tables, procedures, views together. All employee-related objects in the employee schema, etc.

You can also give permissions to just one schema, so that users can only see the schema they have access to and nothing else.

It looks like API level 11 has support for what you need. See WebViewClient.shouldInterceptRequest().

In 5.5

adding

Route::get('logout', 'Auth\LoginController@logout');

to my routes file works fine.

use new JavaScriptSerializer().Deserialize<object>(jsonString)

You need System.Web.Extensions dll and import the following namespace.

Namespace: System.Web.Script.Serialization

for more info MSDN

mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;

These are deprecated use the following..

 // Connects to your Database
            $link = mysqli_connect("localhost", "root", "", "");

and to insert data use the following

 $sql = "INSERT INTO  Table-Name (Column-Name)
VALUES ('$filename')" ;

A lot of the answers on this page only apply to a single cell, and OP asked for all the selected cells.

If all you want is the cell contents, and you don't care about references to the actual cells that are selected, you can just do this:

Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim SelectedThings As String = DataGridView1.GetClipboardContent().GetText().Replace(ChrW(9), ",")
    TextBox1.Text = SelectedThings
End Sub

When Button1 is clicked, this will fill TextBox1 with the comma-separated values of the selected cells.

Split it apart and get the last element:

$end = end(explode('/', $url));
# or:
$end = array_slice(explode('/', $url), -1)[0];

Edit: To support apache-style-canonical URLs, rtrim is handy:

$end = end(explode('/', rtrim($url, '/')));
# or:
$end = array_slice(explode('/', rtrim($url, '/')), -1)[0];

A different example which might me considered more readable is (Demo):

$path = parse_url($url, PHP_URL_PATH);
$pathFragments = explode('/', $path);
$end = end($pathFragments);

This example also takes into account to only work on the path of the URL.

Yet another edit (years after), canonicalization and easy UTF-8 alternative use included (via PCRE regular expression in PHP):

<?php

use function call_user_func as f;
use UnexpectedValueException as e;

$url = 'http://example.com/artist/song/music-videos/song-title/9393903';

$result = preg_match('(([^/]*)/*$)', $url, $m)

    ? $m[1]
    : f(function() use ($url) {throw new e("pattern on '$url'");})
    ;

var_dump($result); # string(7) "9393903"

Which is pretty rough but shows how to wrap this this within a preg_match call for finer-grained control via PCRE regular expression pattern. To add some sense to this bare-metal example, it should be wrapped inside a function of its' own (which would also make the aliasing superfluous). Just presented this way for brevity.

Maybe easy like this?

Compiled binaries of the PHP interpreter can be found at http://www.mamp.info/en/ downloads/index.html . Drop this downloaded folder into your /Applications/MAMP/bin/php! directory. Close and re-open your MAMP PRO application. Your new PHP version should now appear in the PHP drop down menu. MAMP PRO will only support PHP versions from the downloads page.

The basic purpose of ValidateAntiForgeryToken attribute is to prevent cross-site request forgery attacks.

A cross-site request forgery is an attack in which a harmful script element, malicious command, or code is sent from the browser of a trusted user. For more information on this please visit http://www.asp.net/mvc/overview/security/xsrfcsrf-prevention-in-aspnet-mvc-and-web-pages.

It is simple to use, you need to decorate method with ValidateAntiForgeryToken attribute as below:

[HttpPost]  
[ValidateAntiForgeryToken]  
public ActionResult CreateProduct(Product product)  
{
  if (ModelState.IsValid)  
  {
    //your logic 
  }
  return View(ModelName);
}

It is derived from System.Web.Mvc namespace.

And in your view, add this code to add the token so it is used to validate the form upon submission.

@Html.AntiForgeryToken()

Here's a hack which might be helpful... it puts an apostrophe in front of the time value, so when you right-click on the output in SSMS and say "Copy with Headers", then paste into Excel, it preserves the milliseconds / nanoseconds for datetime2 values. It's a bit ugly that it puts the apostrophe there, but it's better than the frustration of dealing with Excel doing unwanted rounding on the time value. The date is a UK format but you can look at the CONVERT function page in MSDN.

SELECT CONVERT(VARCHAR(23), sm.MilestoneDate, 103) AS MilestoneDate, '''' + CONVERT(VARCHAR(23), sm.MilestoneDate, 114) AS MilestoneTime FROM SomeTable sm

Hi Guys if u are using angular plugin in eclipse that time is plugin is limited periods after that if u want to used this plugin then u pay it so i suggest to you used webstrome and visual code ide that are very easy and comfort to used so take care if u start and developed a angular app using eclipse

Try this:

matches = pages | articles | posts

It retains all the functions of the querysets which is nice if you want to order_by or similar.

Please note: this doesn't work on querysets from two different models.

One way to fix up your python2 code is:

import sys

if sys.version_info >= (3, 0):
    def xrange(*args, **kwargs):
        return iter(range(*args, **kwargs))

As mentioned, one way is to use

new Integer(my_int_value)

But you should not call the constructor for wrapper classes directly

So, modify the code accordingly:

mBitmapCache.put(Integer.valueOf(R.drawable.bg1),object);

Correct expression is

"source " + (DT_STR,4,1252)DATEPART( "yyyy" , getdate() ) + "-" +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "mm" , getdate() ), 2) + "-" +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "dd" , getdate() ), 2) +".CSV"

In your Info.plist, Right click in the properties table, click Add Row, add key name App Uses Non-Exempt Encryption with Type Boolean and set value NO.

Another interesting possibility:

1. generate RSA, or DSA key pair (as it was described)
2. put public key to host (as it was already described)
3. run:

rsync --partial --progress --rsh="ssh -i dsa_private_file" host_name@host:/home/me/d .

Note: -i dsa_private_file which is your RSA/DSA private key

Basically, this approach is very similar to the one described by @Mad Scientist, however you do not have to copy your private key to ~/.ssh. In other words, it is useful for ad-hoc tasks (one time passwordless access)

As described in Cast Functions and Operators:

The type for the result can be one of the following values:

• BINARY[(N)]
• CHAR[(N)]
• DATE
• DATETIME
• DECIMAL[(M[,D])]
• SIGNED [INTEGER]
• TIME
• UNSIGNED [INTEGER]

Therefore, you should use:

SELECT CAST(PROD_CODE AS UNSIGNED) FROM PRODUCT

If you're looking for a way to change this through the GUI, at least in the current version 1.10.1 if you hover over the OPEN EDITORS group in the EXPLORER pane a button appears that toggles the editor group layout between horizontal and vertical.

If your issue is related to a failed Windows install, and you are receiving a message related to installer _jsnode_windows.msi CRC error:

Aptana Studio (Aptana Studio 3, build: 3.6.1.201410201044) currently requires Nodejs 0.5.XX-0.11.xx

Even though the current release of nodejs seems to be 5.X.X . Apparently there will be a new release in Nov 2015 that corrects this defect.

Pre-installing x0.10.36-x64 allowed me to proceed with a successful install. If version numbers can be believed, this seems to be an ancient release of nodejs, but hey - I saw a very impressive demo of Aptana Studio and really wanted to install it. :-)

I also pre-installed GIT for windows, but I'm not sure if that was necessary or not.

While you unfortunately cannot convert an existing member function pointer to a plain function pointer, you can create an adapter function template in a fairly straightforward way that wraps a member function pointer known at compile-time in a normal function like this:

template <class Type>
struct member_function;

template <class Type, class Ret, class... Args>
struct member_function<Ret(Type::*)(Args...)>
{
    template <Ret(Type::*Func)(Args...)>
    static Ret adapter(Type &obj, Args&&... args)
    {
        return (obj.*Func)(std::forward<Args>(args)...);
    }
};

template <class Type, class Ret, class... Args>
struct member_function<Ret(Type::*)(Args...) const>
{
    template <Ret(Type::*Func)(Args...) const>
    static Ret adapter(const Type &obj, Args&&... args)
    {
        return (obj.*Func)(std::forward<Args>(args)...);
    }
};

int (*func)(A&) = &member_function<decltype(&A::f)>::adapter<&A::f>;

Note that in order to call the member function, an instance of A must be provided.

[I realize this question is a million years old, but there is a deeper question (or two) at its heart, about OP, the pedagogy of programming, and about assumption-making.]

A few people, including a mod, have suggested this is impossible. And, in some--including the most obvious--contexts, it is. But it's interesting to see that that wasn't immediately obvious to the OP.

The impossibility assumes that the contex is running an executable compiled from C on a line-oriented text console (e.g., console+sh or X-term+csh or Terminal+bash), which is a very reasonable assumption. But the fact that the "right" answer ("%8d") wasn't good enough for OP while also being non-obvious suggests that there's a pretty big can of worms nearby...

Consider Curses (and its many variants). In it, you can navigate the "screen", and "move" the cursor around, and "repaint" portions (windows) of text-based output. In a Curses context, it absolutely would be possible to do; i.e., dynamically resize a "window" to accommodate a larger number. But even Curses is just a screen "painting" abstraction. No one suggested it, and probably rightfully so, because a Curses implementation in C doesn't mean it's "strictly C". Fine.

But what does this really mean? In order for the response: "it's impossible" to be correct, it would mean that we're saying something about the runtime system. In other words, this isn't theoretical, (as in, "How do I sort a statically-allocated array of ints?"), which can be explained as a "closed system" that totally ignores any aspect of the runtime.

But, in this case, we have I/O: specifically, the implementation of printf(). But that's where there's an opportunity to have said something more interesting in response (even though, admittedly, the asker was probably not digging quite this deep).

Suppose we use a different set of assumptions. Suppose OP is reasonably "clever" and understands that it would not be possible to to edit previous lines on a line-oriented stream (how would you correct the horizontal position of a character output by a line-printer??). Suppose also, that OP isn't just a kid working on a homework assignment and not realizing it was a "trick" question, intended to tease out an exploration of the meaning of "stream abstraction". Further, let's suppose OP was wondering: "Wait...If C's runtime environment supports the idea of STDOUT--and if STDOUT is just an abstraction--why isn't it just as reasonable to have a terminal abstraction that 1) can vertically scroll but 2) supports a positionable cursor? Both are moving text on a screen."

Because if that were the question we're trying to answer, then you'd only have to look as far as:

ANSI Escape Codes

to see that:

Almost all manufacturers of video terminals added vendor-specific escape sequences to perform operations such as placing the cursor at arbitrary positions on the screen. One example is the VT52 terminal, which allowed the cursor to be placed at an x,y location on the screen by sending the ESC character, a Y character, and then two characters representing with numerical values equal to the x,y location plus 32 (thus starting at the ASCII space character and avoiding the control characters). The Hazeltine 1500 had a similar feature, invoked using ~, DC1 and then the X and Y positions separated with a comma. While the two terminals had identical functionality in this regard, different control sequences had to be used to invoke them.

The first popular video terminal to support these sequences was the Digital VT100, introduced in 1978. This model was very successful in the market, which sparked a variety of VT100 clones, among the earliest and most popular of which was the much more affordable Zenith Z-19 in 1979. Others included the Qume QVT-108, Televideo TVI-970, Wyse WY-99GT as well as optional "VT100" or "VT103" or "ANSI" modes with varying degrees of compatibility on many other brands. The popularity of these gradually led to more and more software (especially bulletin board systems and other online services) assuming the escape sequences worked, leading to almost all new terminals and emulator programs supporting them.

It has been possible, as early as 1978. C itself was "born" in 1972, and the K&R version was established in 1978. If "ANSI" escape sequences were around at that time, then there is an answer "in C" if we're willing to also stipulate: "Well, assuming your terminal is VT100-capable." Incidentally, the consoles which don't support ANSI escapes? You guessed it: Windows & DOS consoles. But on almost every other platform (Unices, Vaxen, Mac OS, Linux) you can expect to.

TL;DR - There is no reasonable answer that can be given without stating assumptions about the runtime environment. Since most runtimes (unless you're using desktop-computer-market-share-of-the-80's-and-90's to calculate 'most') would have, (since the time of the VT-52!), then I don't think it's entirely justified to say that it's impossible--just that in order for it to be possible, it's an entire different order of magnitude of work, and not as simple as %8d...which it kinda seemed like the OP knew about.

We just have to clarify the assumptions.

And lest one thinks that I/O is exceptional, i.e., the only time we need to think about the runtime, (or even the hardware), just dig into IEEE 754 Floating Point exception handling. For those interested:

Intel Floating Point Case Study

According to Professor William Kahan, University of California at Berkeley, a classic case occurred in June 1996. A satellite-lifting rocket named Ariane 5 turned cartwheels shortly after launch and scattered itself and a payload worth over half a billion dollars over a marsh in French Guiana. Kahan found the disaster could be blamed upon a programming language that disregarded the default exception-handling specifications in IEEE 754. Upon launch, sensors reported acceleration so strong that it caused a conversion-to-integer overflow in software intended for recalibration of the rocket’s inertial guidance while on the launching pad.

Particularly for node, the documentation for the http server component, under event connection says:

[Triggered] when a new TCP stream is established. [The] socket is an object of type net.Socket. Usually users will not want to access this event. In particular, the socket will not emit readable events because of how the protocol parser attaches to the socket. The socket can also be accessed at request.connection.

So, that means request.connection is a socket and according to the documentation there is indeed a socket.remoteAddress attribute which according to the documentation is:

The string representation of the remote IP address. For example, '74.125.127.100' or '2001:4860:a005::68'.

Under express, the request object is also an instance of the Node http request object, so this approach should still work.

However, under Express.js the request already has two attributes: req.ip and req.ips

req.ip

Return the remote address, or when "trust proxy" is enabled - the upstream address.

req.ips

When "trust proxy" is true, parse the "X-Forwarded-For" ip address list and return an array, otherwise an empty array is returned. For example if the value were "client, proxy1, proxy2" you would receive the array ["client", "proxy1", "proxy2"] where "proxy2" is the furthest down-stream.

It may be worth mentioning that, according to my understanding, the Express req.ip is a better approach than req.connection.remoteAddress, since req.ip contains the actual client ip (provided that trusted proxy is enabled in express), whereas the other may contain the proxy's IP address (if there is one).

That is the reason why the currently accepted answer suggests:

var ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress;

The req.headers['x-forwarded-for'] will be the equivalent of express req.ip.

You can use inWaiting() to get the amount of bytes available at the input queue.

Then you can use read() to read the bytes, something like that:

While True:
    bytesToRead = ser.inWaiting()
    ser.read(bytesToRead)

Why not to use readline() at this case from Docs:

Read a line which is terminated with end-of-line (eol) character (\n by default) or until timeout.

You are waiting for the timeout at each reading since it waits for eol. the serial input Q remains the same it just a lot of time to get to the "end" of the buffer, To understand it better: you are writing to the input Q like a race car, and reading like an old car :)

One thing you could do would be to create a dictionary. Might be a little sloppy considering your looking for 64 elements but it gets the job done. Im not sure if its the "preferred way" to do it but it worked for me using an array of structs.

var tasks = [0:[forTasks](),1:[forTasks](),2:[forTasks](),3:[forTasks](),4:[forTasks](),5:[forTasks](),6:[forTasks]()]

Unfortunately to be able to use the extension modules provided by others you'll be forced to use the official compiler to compile Python. These are:

• Visual Studio 2008 for Python 2.7. See: https://docs.python.org/2.7/using/windows.html#compiling-python-on-windows

• Visual Studio 2010 for Python 3.4. See: https://docs.python.org/3.4/using/windows.html#compiling-python-on-windows

Alternatively, you can use MinGw to compile extensions in a way that won't depend on others.

See: https://docs.python.org/2/install/#gnu-c-cygwin-MinGW or https://docs.python.org/3.4/install/#gnu-c-cygwin-mingw

This allows you to have one compiler to build your extensions for both versions of Python, Python 2.x and Python 3.x.

Just to add to Alex Poole's answer, here is how you do the date and time:

    TO_DATE('31/DEC/2017 12:59:59', 'dd/mm/yyyy hh24:mi:ss')

What does your text file look like?? Each line a record?

You'll have to check out the BULK INSERT statement - that should look something like:

BULK INSERT dbo.YourTableName
FROM 'D:\directory\YourFileName.csv'
WITH
(
  CODEPAGE = '1252',
  FIELDTERMINATOR = ';',
  CHECK_CONSTRAINTS
) 

Here, in my case, I'm importing a CSV file - but you should be able to import a text file just as well.

From the MSDN docs - here's a sample that hopefully works for a text file with one field per row:

BULK INSERT dbo.temp 
   FROM 'c:\temp\file.txt'
   WITH 
      (
         ROWTERMINATOR ='\n'
      )

Seems to work just fine in my test environment :-)

This page has a table of string constants including vbCrLf

vbCrLf | Chr(13) & Chr(10) | Carriage return–linefeed combination

String guid = System.Guid.NewGuid().ToString();

Otherwise it's a delegate.

You can convert most of the columns by just calling convert_objects:

In [36]:

df = df.convert_objects(convert_numeric=True)
df.dtypes
Out[36]:
Date         object
WD            int64
Manpower    float64
2nd          object
CTR          object
2ndU        float64
T1            int64
T2          int64
T3           int64
T4        float64
dtype: object

For column '2nd' and 'CTR' we can call the vectorised str methods to replace the thousands separator and remove the '%' sign and then astype to convert:

In [39]:

df['2nd'] = df['2nd'].str.replace(',','').astype(int)
df['CTR'] = df['CTR'].str.replace('%','').astype(np.float64)
df.dtypes
Out[39]:
Date         object
WD            int64
Manpower    float64
2nd           int32
CTR         float64
2ndU        float64
T1            int64
T2            int64
T3            int64
T4           object
dtype: object
In [40]:

df.head()
Out[40]:
        Date  WD  Manpower   2nd   CTR  2ndU   T1    T2   T3     T4
0   2013/4/6   6       NaN  2645  5.27  0.29  407   533  454    368
1   2013/4/7   7       NaN  2118  5.89  0.31  257   659  583    369
2  2013/4/13   6       NaN  2470  5.38  0.29  354   531  473    383
3  2013/4/14   7       NaN  2033  6.77  0.37  396   748  681    458
4  2013/4/20   6       NaN  2690  5.38  0.29  361   528  541    381

Or you can do the string handling operations above without the call to astype and then call convert_objects to convert everything in one go.

UPDATE

Since version 0.17.0 convert_objects is deprecated and there isn't a top-level function to do this so you need to do:

df.apply(lambda col:pd.to_numeric(col, errors='coerce'))

See the docs and this related question: pandas: to_numeric for multiple columns

In Spyder 4.1, you can change background color from: Tools > Preferences > Appearance > Syntax highlighting scheme

I don't know what you want to do, but this is how I actually translated your example code....

package test;

/**
 * @author The Elite Gentleman
 *
 */
public enum Strings {
    STRING_ONE("ONE"),
    STRING_TWO("TWO")
    ;

    private final String text;

    /**
     * @param text
     */
    Strings(final String text) {
        this.text = text;
    }

    /* (non-Javadoc)
     * @see java.lang.Enum#toString()
     */
    @Override
    public String toString() {
        return text;
    }
}

Alternatively, you can create a getter method for text.

You can now do Strings.STRING_ONE.toString();

foreach($xml->code as $vals )
{ 
    unset($geonames);
    $vals=(array)$vals;
    foreach($vals as $key => $value)
      {
        $value=(array)$value;
        $geonames[$key]=$value[0];
      }
}
print_r($geonames);

If all you want is any day in the last month, the simplest thing you can do is subtract the number of days from the current date, which will give you the last day of the previous month.

For instance, starting with any date:

>>> import datetime                                                                                                                                                                 
>>> today = datetime.date.today()                                                                                                                                                   
>>> today
datetime.date(2016, 5, 24)

Subtracting the days of the current date we get:

>>> last_day_previous_month = today - datetime.timedelta(days=today.day)
>>> last_day_previous_month
datetime.date(2016, 4, 30)

This is enough for your simplified need of any day in the last month.

But now that you have it, you can also get any day in the month, including the same day you started with (i.e. more or less the same as subtracting a month):

>>> same_day_last_month = last_day_previous_month.replace(day=today.day)
>>> same_day_last_month
datetime.date(2016, 4, 24)

Of course, you need to be careful with 31st on a 30 day month or the days missing from February (and take care of leap years), but that's also easy to do:

>>> a_date = datetime.date(2016, 3, 31)                                                                                                                                             
>>> last_day_previous_month = a_date - datetime.timedelta(days=a_date.day)
>>> a_date_minus_month = (
...     last_day_previous_month.replace(day=a_date.day)
...     if a_date.day < last_day_previous_month.day
...     else last_day_previous_month
... )
>>> a_date_minus_month
datetime.date(2016, 2, 29)

At a very generic level

UPDATE MyTable

SET StringColumn = REPLACE (StringColumn, 'SearchForThis', 'ReplaceWithThis')

WHERE SomeOtherColumn LIKE '%PATTERN%'

In your case you say these were escaped but since you don't specify how they were escaped, let's say they were escaped to GREATERTHAN

UPDATE MyTable

SET StringColumn = REPLACE (StringColumn, 'GREATERTHAN', '>')

WHERE articleItem LIKE '%GREATERTHAN%'

Since your query is actually going to be working inside the string, your WHERE clause doing its pattern matching is unlikely to improve any performance - it is actually going to generate more work for the server. Unless you have another WHERE clause member that is going to make this query perform better, you can simply do an update like this:

UPDATE MyTable
SET StringColumn = REPLACE (StringColumn, 'GREATERTHAN', '>')

You can also nest multiple REPLACE calls

UPDATE MyTable
SET StringColumn = REPLACE (REPLACE (StringColumn, 'GREATERTHAN', '>'), 'LESSTHAN', '<')

You can also do this when you select the data (as opposed to when you save it).

So instead of :

SELECT MyURLString From MyTable

You could do

SELECT REPLACE (MyURLString, 'GREATERTHAN', '>') as MyURLString From MyTable

The Spring documentation describes the following standard scopes:

singleton: (Default) Scopes a single bean definition to a single object instance per Spring IoC container.

prototype: Scopes a single bean definition to any number of object instances.

request: Scopes a single bean definition to the lifecycle of a single HTTP request; that is, each HTTP request has its own instance of a bean created off the back of a single bean definition. Only valid in the context of a web-aware Spring ApplicationContext.

session: Scopes a single bean definition to the lifecycle of an HTTP Session. Only valid in the context of a web-aware Spring ApplicationContext.

global session: Scopes a single bean definition to the lifecycle of a global HTTP Session. Typically only valid when used in a portlet context. Only valid in the context of a web-aware Spring ApplicationContext.

Additional custom scopes can also be created and configured using a CustomScopeConfigurer. An example would be the flow scope added by Spring Webflow.

By the way, you argues that you always used prototype what I find strange. The standard scope is singleton and in the application I develop, I rarely need the prototype scope. You should maybe take a look at this.

you can try this with list comprehension like the following

matrix = [['a','b','c'],['d','e','f'],['g','h','i']] n = len(matrix) transpose = [[row[i] for row in matrix] for i in range(n)] print (transpose)

No jQuery is necessary in this situation.

window.opener.location.reload(false);

https://developer.mozilla.org/en-US/docs/Web/API/Window

The implementation of String.valueOf() that you see is the simplest way to meet the contract specified in the API: "The representation is exactly the one returned by the Integer.toString() method of one argument."

use below code

server.mappath() in asp.net

application.startuppath in c# windows application

$('img.conversation_img[alt="example"]')
    .each(function(){
         alert($(this).attr('src'))
    });

This will display src attributes of all images of class 'conversation_img' with alt='example'

This should work.

$(".formData").val("valuesgoeshere")

For empty

$(".formData").val("")

If this does not work, you should post a jsFiddle.

Demo:

$(function() {_x000D_
  $(".resetInput").on("click", function() {_x000D_
    $(".formData").val("");_x000D_
  });_x000D_
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<input type="text" class="formData" value="yoyoyo">_x000D_
_x000D_
_x000D_
<button class="resetInput">Click Here to reset</button>

EDIT 2 (For IE10-11 Users): The solution above will not work with the changes Microsoft has made to the browser as of late, so here's an updated solution that will allow you to grayscale (or desaturate) your images.

Hope this helps. Even Apple's Documentation on the matter is incomplete.

Update: Apple has introduced a new Media Manager which requires only that you create artwork for the largest iPhone and/or iPad devices. The smaller images will be created for you. Note that if you hadn't been creating iPad Pro images before, you have to now (if you support iPad).

Update: Screenshots and app previews for new devices now supported.

If you use Maven, you must to declare your source and test folder in project directory.

For these, click F4 on Intellij Idea and Open Project Structure. Select your project name on the left panel and Mark As your "Source" and "Test" directory.

Are you trying to pass the command line arguments to the program AS you launch it? I am working on something right now that does exactly this, and it was a lot simpler than I thought. If I go into the command line, and type

C:\folder\app.exe/xC:\folder\file.txt

then my application launches, and creates a file in the specified directory with the specified name.

I wanted to do this through a Powershell script on a remote machine, and figured out that all I needed to do was put

$s = New-PSSession -computername NAME -credential LOGIN
    Invoke-Command -session $s -scriptblock {C:\folder\app.exe /xC:\folder\file.txt}
Remove-PSSession $s

(I have a bunch more similar commands inside the session, this is just the minimum it requires to run) notice the space between the executable, and the command line arguments. It works for me, but I am not sure exactly how your application works, or if that is even how you pass arguments to it.

*I can also have my application push the file back to my own local computer by changing the script-block to

C:\folder\app.exe /x"\\LocalPC\DATA (C)\localfolder\localfile.txt"

You need the quotes if your file-path has a space in it.

EDIT: actually, this brought up some silly problems with Powershell launching the application as a service or something, so I did some searching, and figured out that you can call CMD to execute commands for you on the remote computer. This way, the command is carried out EXACTLY as if you had just typed it into a CMD window on the remote machine. Put the command in the scriptblock into double quotes, and then put a cmd.exe /C before it. like this:

cmd.exe /C "C:\folder\app.exe/xC:\folder\file.txt"

this solved all of the problems that I have been having recently.

EDIT EDIT: Had more problems, and found a much better way to do it.

start-process -filepath C:\folder\app.exe -argumentlist "/xC:\folder\file.txt"

and this doesn't hang up your terminal window waiting for the remote process to end. Just make sure you have a way to terminate the process if it doesn't do that on it's own. (mine doesn't, required the coding of another argument)

You could try:

export ENVVAR=value

in virtualenv_root/bin/activate. Basically the activate script is what is executed when you start using the virtualenv so you can put all your customization in there.

Try running fuser command

[root@guest2 ~]# fuser -mv /home

USER PID ACCESS COMMAND

/home: root 2919 f.... automount

[root@guest2 ~]# kill -9 2919

autofs service is known to cause this issue.

You can use command

#service autofs stop

And try again.

there are many causes such as

• The network link between server and client may be temporarily going down.
• running out of system resources.
• sending malformed data.

To examine the problem in detail, you can use Wireshark.

or you can just re-request or re-connect again.

as per latest version of ASP.net WebApi 2,

under WebApiConfig.cs , this will work

config.Formatters.Remove(GlobalConfiguration.Configuration.Formatters.XmlFormatter);
config.Formatters.Add(GlobalConfiguration.Configuration.Formatters.JsonFormatter);

If you want to visualize your dependencies in a graph you can use gradle-dependency-graph-generator plugin.

Generally the output of this plugin can be found in build/reports/dependency-graph directory and it contains three files (.dot|.png|.svg) if you are using the 0.5.0 version of the plugin.

Example of dependences graph in a real app (Chess Clock):

Use the -s option BEFORE the command to specify the device, for example:

adb -s 7f1c864e shell

You need to click Log Navigator icon (far right in left sidebar). Then choose your Debug/Run session in left sidebar, and you will have console in editor area.

I use a while loop to get the result:

i = 0
while i < len(a)-1:
   result = (a[i]+a[i+1])/2
   print result
   i +=1

It looks like you're using python 3.x. In python3, filter, map, zip, etc return an object which is iterable, but not a list. In other words,

filter(func,data) #python 2.x

is equivalent to:

list(filter(func,data)) #python 3.x

I think it was changed because you (often) want to do the filtering in a lazy sense -- You don't need to consume all of the memory to create a list up front, as long as the iterator returns the same thing a list would during iteration.

If you're familiar with list comprehensions and generator expressions, the above filter is now (almost) equivalent to the following in python3.x:

( x for x in data if func(x) ) 

As opposed to:

[ x for x in data if func(x) ]

in python 2.x

When working with async functions or observables provided by 3rd party libraries, for example Cloud firestore, I've found functions the waitFor method shown below (TypeScript, but you get the idea...) to be helpful when you need to wait on some process to complete, but you don't want to have to embed callbacks within callbacks within callbacks nor risk an infinite loop.

This method is sort of similar to a while (!condition) sleep loop, but yields asynchronously and performs a test on the completion condition at regular intervals till true or timeout.

export const sleep = (ms: number) => {
    return new Promise(resolve => setTimeout(resolve, ms))
}
/**
 * Wait until the condition tested in a function returns true, or until 
 * a timeout is exceeded.
 * @param interval The frenequency with which the boolean function contained in condition is called.
 * @param timeout  The maximum time to allow for booleanFunction to return true
 * @param booleanFunction:  A completion function to evaluate after each interval. waitFor will return true as soon as the completion function returns true.   
 */
export const waitFor = async function (interval: number, timeout: number,
    booleanFunction: Function): Promise<boolean> {
    let elapsed = 1;
    if (booleanFunction()) return true;
    while (elapsed < timeout) {
        elapsed += interval;
        await sleep(interval);
        if (booleanFunction()) {
            return true;
        }
    }
    return false;
}

The say you have a long running process on your backend you want to complete before some other task is undertaken. For example if you have a function that totals a list of accounts, but you want to refresh the accounts from the backend before you calculate, you can do something like this:

async recalcAccountTotals() : number {
     this.accountService.refresh();   //start the async process.
     if (this.accounts.dirty) {
           let updateResult = await waitFor(100,2000,()=> {return !(this.accounts.dirty)})
     }
 if(!updateResult) { 
      console.error("Account refresh timed out, recalc aborted");
      return NaN;
    }
 return ... //calculate the account total. 
}

You can try this!

python manage.py migrate --run-syncdb

I have the same problem with Django 1.9 and 1.10. This code works!

1) you may have to increase the timeout on your connection.

2)You can get more information about the lost connections by starting mysqld with the --log-warnings=2 option.

This logs some of the disconnected errors in the hostname.err file

You can use that for further investigation

3) if you are trying to send the data to BLOB columns, check server's max_allowed_packet variable, which has a default value of 1MB. You may also need to increase the maximum packet size on the client end. More information on setting the packet size is given in following link, “Packet too large”.

4) you can check the following url link

5) you should check your available disk space is bigger than the table you're trying to update link

I usually handle things like this with an extension method. Here is one way implemented in a console app:

namespace ConsoleApplication10
{
    class Program
    {
        static void Main(string[] args)
        {
            CheckIfNumeric("A");
            CheckIfNumeric("22");
            CheckIfNumeric("Potato");
            CheckIfNumeric("Q");
            CheckIfNumeric("A&^*^");

            Console.ReadLine();
        }

        private static void CheckIfNumeric(string input)
        {
            if (input.IsNumeric())
            {
                Console.WriteLine(input + " is numeric.");
            }
            else
            {
                Console.WriteLine(input + " is NOT numeric.");
            }
        }
    }

    public static class StringExtensions
    {
        public static bool IsNumeric(this string input)
        {
            return Regex.IsMatch(input, @"^\d+$");
        }
    }
}

Output:

A is NOT numeric.

22 is numeric.

Potato is NOT numeric.

Q is NOT numeric.

A&^*^ is NOT numeric.

Note, here are a few other ways to check for numbers using RegEx.

Use Meta-b / Meta-f to move backward/forward by a word respectively.

In OSX, Meta translates as ESC, which sucks.

But alternatively, you can open terminal preferences -> settings -> profile -> keyboard and check "use option as meta key"

Getting cuDNN Version [Linux]

Use following to find path for cuDNN:

cat $(whereis cudnn.h) | grep CUDNN_MAJOR -A 2

If above doesn't work try this:

cat $(whereis cuda)/include/cudnn.h | grep CUDNN_MAJOR -A 2

Getting cuDNN Version [Windows]

Use following to find path for cuDNN:

C:\>where cudnn*
C:\Program Files\cuDNN6\cuda\bin\cudnn64_6.dll

Then use this to dump version from header file,

type "%PROGRAMFILES%\cuDNN6\cuda\include\cudnn.h" | findstr "CUDNN_MAJOR CUDNN_MINOR CUDNN_PATCHLEVEL"

Getting CUDA Version

This works on Linux as well as Windows:

nvcc --version

in case if your table has tbody

let tbl = document.getElementById("tbl").getElementsByTagName('tbody')[0];
console.log(tbl.rows[0].cells[0].innerHTML)

You should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3 (and uses it as default), so switch back to a value of 2 which can be read by Python 2.

Check the protocolparameter in pickle.dump. Your resulting code will look like this.

pickle.dump(your_object, your_file, protocol=2)

There is no protocolparameter in pickle.load because pickle can determine the protocol from the file.

This trick works for me. Hope this could help you. Let's save the followings as checkRunningProcess.sh

#!/bin/bash
ps_out=`ps -ef | grep $1 | grep -v 'grep' | grep -v $0`
result=$(echo $ps_out | grep "$1")
if [[ "$result" != "" ]];then
    echo "Running"
else
    echo "Not Running"
fi

Make the checkRunningProcess.sh executable.And then use it.
Example to use.

20:10 $ checkRunningProcess.sh proxy.py
Running
20:12 $ checkRunningProcess.sh abcdef
Not Running

I think the issue is that you have

android:prompt="@string/level_array"

and you don't have any string with the id, to refer to the array, you need to use @array

test this or put a screen of your log please

run:

mvn -U dependency:go-offline

It works for me.

To add to the above answers, there's a good article: Useful JVM Flags – Part 8 (GC Logging) by Patrick Peschlow.

A brief excerpt:

The flag -XX:+PrintGC (or the alias -verbose:gc) activates the “simple” GC logging mode

By default the GC log is written to stdout. With -Xloggc:<file> we may instead specify an output file. Note that this flag implicitly sets -XX:+PrintGC and -XX:+PrintGCTimeStamps as well.

If we use -XX:+PrintGCDetails instead of -XX:+PrintGC, we activate the “detailed” GC logging mode which differs depending on the GC algorithm used.

With -XX:+PrintGCTimeStamps a timestamp reflecting the real time passed in seconds since JVM start is added to every line.

If we specify -XX:+PrintGCDateStamps each line starts with the absolute date and time.

The following code stops the execution right after an exception is thrown. You need to set a windows_exception_handler along with a termination handler. I tested this in MinGW 32bits.

void beforeCrash(void);

static const bool SET_TERMINATE = std::set_terminate(beforeCrash);

void beforeCrash() {
    __asm("int3");
}

int main(int argc, char *argv[])
{
SetUnhandledExceptionFilter(windows_exception_handler);
...
}

Check the following code for the windows_exception_handler function: http://www.codedisqus.com/0ziVPgVPUk/exception-handling-and-stacktrace-under-windows-mingwgcc.html

$.inArray returns the index of the element if found or -1 if it isn't -- not a boolean value. So the correct is

if(jQuery.inArray("test", myarray) != -1) {
    console.log("is in array");
} else {
    console.log("is NOT in array");
} 

You mean Selenium WebDriver? Huh....

Prerequisite: Install Python based on your OS

Install with following command

pip install -U selenium

And use this module in your code

from selenium import webdriver

You can also use many of the following as required

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException

Here is an updated answer

I would recommend you to run script without IDE... Here is my approach

1. USE IDE to find xpath of object / element
2. And use find_element_by_xpath().click()

An example below shows login page automation

#ScriptName : Login.py
#---------------------
from selenium import webdriver

#Following are optional required
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException

baseurl = "http://www.mywebsite.com/login.php"
username = "admin"
password = "admin"

xpaths = { 'usernameTxtBox' : "//input[@name='username']",
           'passwordTxtBox' : "//input[@name='password']",
           'submitButton' :   "//input[@name='login']"
         }

mydriver = webdriver.Firefox()
mydriver.get(baseurl)
mydriver.maximize_window()

#Clear Username TextBox if already allowed "Remember Me" 
mydriver.find_element_by_xpath(xpaths['usernameTxtBox']).clear()

#Write Username in Username TextBox
mydriver.find_element_by_xpath(xpaths['usernameTxtBox']).send_keys(username)

#Clear Password TextBox if already allowed "Remember Me" 
mydriver.find_element_by_xpath(xpaths['passwordTxtBox']).clear()

#Write Password in password TextBox
mydriver.find_element_by_xpath(xpaths['passwordTxtBox']).send_keys(password)

#Click Login button
mydriver.find_element_by_xpath(xpaths['submitButton']).click()

There is an another way that you can find xpath of any object -

1. Install Firebug and Firepath addons in firefox
2. Open URL in Firefox
3. Press F12 to open Firepath developer instance
4. Select Firepath in below browser pane and chose select by "xpath"
5. Move cursor of the mouse to element on webpage
6. in the xpath textbox you will get xpath of an object/element.
7. Copy Paste xpath to the script.

Run script -

python Login.py

You can also use a CSS selector instead of xpath. CSS selectors are slightly faster than xpath in most cases, and are usually preferred over xpath (if there isn't an ID attribute on the elements you're interacting with).

Firepath can also capture the object's locator as a CSS selector if you move your cursor to the object. You'll have to update your code to use the equivalent find by CSS selector method instead -

find_element_by_css_selector(css_selector) 

  int arr[]={4,7,2,21321,657,12321};
  int length =arr.length;
  System.out.println(length); // will return 6

  int arr2[] = new int[10];
   arr2[3] = 4;
  int length2 =arr2.length;
  System.out.println(length2); // // will return 10. all other digits will be 0 initialize because staic memory initialization

The best and convenient approach is calling fragment instance and send data at that time. every fragment by default have instance method

For example : if your fragment name is MyFragment

so you will call your fragment from activity like this :

getSupportFragmentManager().beginTransaction().add(R.id.container, MyFragment.newInstance("data1","data2"),"MyFragment").commit();

*R.id.container is a id of my FrameLayout

so in MyFragment.newInstance("data1","data2") you can send data to fragment and in your fragment you get this data in MyFragment newInstance(String param1, String param2)

public static MyFragment newInstance(String param1, String param2) {
        MyFragment fragment = new MyFragment();
        Bundle args = new Bundle();
        args.putString(ARG_PARAM1, param1);
        args.putString(ARG_PARAM2, param2);
        fragment.setArguments(args);
        return fragment;
    }

and then in onCreate method of fragment you'll get the data:

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mParam1 = getArguments().getString(ARG_PARAM1);
            mParam2 = getArguments().getString(ARG_PARAM2);
        }
    }

so now mParam1 have data1 and mParam2 have data2

now you can use this mParam1 and mParam2 in your fragment.

You should make a habit of looking at the documentation for stuff like this. It's very useful and will improve your skills very quickly. Here's the relevant bit when you do git help diff

   git diff [options] [--no-index] [--] <path> <path>

The two <path>s are what you need to change to the directories in question.

Well, timing to the rescue again. It seems switch is generally faster than if statements. So that, and the fact that the code is shorter/neater with a switch statement leans in favor of switch:

# Simplified to only measure the overhead of switch vs if

test1 <- function(type) {
 switch(type,
        mean = 1,
        median = 2,
        trimmed = 3)
}

test2 <- function(type) {
 if (type == "mean") 1
 else if (type == "median") 2
 else if (type == "trimmed") 3
}

system.time( for(i in 1:1e6) test1('mean') ) # 0.89 secs
system.time( for(i in 1:1e6) test2('mean') ) # 1.13 secs
system.time( for(i in 1:1e6) test1('trimmed') ) # 0.89 secs
system.time( for(i in 1:1e6) test2('trimmed') ) # 2.28 secs

Update With Joshua's comment in mind, I tried other ways to benchmark. The microbenchmark seems the best. ...and it shows similar timings:

> library(microbenchmark)
> microbenchmark(test1('mean'), test2('mean'), times=1e6)
Unit: nanoseconds
           expr  min   lq median   uq      max
1 test1("mean")  709  771    864  951 16122411
2 test2("mean") 1007 1073   1147 1223  8012202

> microbenchmark(test1('trimmed'), test2('trimmed'), times=1e6)
Unit: nanoseconds
              expr  min   lq median   uq      max
1 test1("trimmed")  733  792    843  944 60440833
2 test2("trimmed") 2022 2133   2203 2309 60814430

Final Update Here's showing how versatile switch is:

switch(type, case1=1, case2=, case3=2.5, 99)

This maps case2 and case3 to 2.5 and the (unnamed) default to 99. For more information, try ?switch

For any OS

This helped me so I'll put it here, just in case. Once you are done with adding the rsa keys for both the accounts, add a config file in your .ssh directory for both the accounts (.ssh/config)

# First account
Host github.com-<FIRST_ACCOUNT_USERNAME_HERE>
   HostName github.com
   User git
   IdentityFile ~/.ssh/id_rsa_user1
   
# Second account
Host github.com-<SECOND_ACCOUNT_USERNAME_HERE>   
   HostName github.com
   User git
   IdentityFile ~/.ssh/id_rsa_user2

Make sure you use the correct usernames and RSA files. Next, you can open the terminal/git bash on the repository root and check which account you would be pushing from

git config user.email

Suppose this returns the first user email and you want to push from the second user. Change the local user.name and user.email :

git config user.name "SECOND_USER"
git config user.email "[email protected]"

(This won't change the global config and you can have the first user set up as the global user). Once done, you can confirm with git config user.email and it should return the email of the second user. You're all set to push to GitHub with the second user. The rest is all the same old git add , git commit and git push. To push from the first user, change the local user.name again and follow the same steps. Hope it helps :)

If the above steps are still not working for you, check to see if you have uploaded the RSA keys within GitHub portal. Refer to GitHub documentation:

Then, clear your ssh cached keys Reference

ssh-add -D

Then add you 2 ssh keys

ssh-add ~/.ssh/id_rsa_user1
ssh-add ~/.ssh/id_rsa_user2

Then type in your terminal:

ssh -T [email protected]<SECOND_ACCOUNT_USERNAME_HERE>

You should see the following output:

Hi <SECOND_USERNAME>! You've successfully authenticated, but GitHub does not provide shell access.

Then, assign the correct remote to your local repository. Make sure you put the same username as the one you gave in your .ssh/config file next to Host. In the following case [email protected]<SECOND_ACCOUNT_USERNAME_HERE>.

git remote rm origin
git remote add origin [email protected]<SECOND_ACCOUNT_USERNAME_HERE>:/your_username/your_repository.git

How about something like: Using HTML Agility Pack

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(@"<html><body><p><table id=""foo""><tr><th>hello</th></tr><tr><td>world</td></tr></table></body></html>");
foreach (HtmlNode table in doc.DocumentNode.SelectNodes("//table")) {
    Console.WriteLine("Found: " + table.Id);
    foreach (HtmlNode row in table.SelectNodes("tr")) {
        Console.WriteLine("row");
        foreach (HtmlNode cell in row.SelectNodes("th|td")) {
            Console.WriteLine("cell: " + cell.InnerText);
        }
    }
}

Note that you can make it prettier with LINQ-to-Objects if you want:

var query = from table in doc.DocumentNode.SelectNodes("//table").Cast<HtmlNode>()
            from row in table.SelectNodes("tr").Cast<HtmlNode>()
            from cell in row.SelectNodes("th|td").Cast<HtmlNode>()
            select new {Table = table.Id, CellText = cell.InnerText};

foreach(var cell in query) {
    Console.WriteLine("{0}: {1}", cell.Table, cell.CellText);
}

Becomes more difficult when you need year and week.
Try to find out which week is 01.01.2017.
(It is the 52nd week of 2016, which is from Mon 26.12.2016 - Sun 01.01.2017).

After a longer search I found

strftime('%G-%V',strtotime("2017-01-01"))

Result: 2016-52

https://www.php.net/manual/de/function.strftime.php
ISO-8601:1988 week number of the given year, starting with the first week of the year with at least 4 weekdays, with Monday being the start of the week. (01 through 53)

The equivalent in mysql is DATE_FORMAT(date, '%x-%v') https://www.w3schools.com/sql/func_mysql_date_format.asp
Week where Monday is the first day of the week (01 to 53).

Could not find a corresponding solution with date() or DateTime.
At least not without solutions like "+1day, last monday".

Use the analytic function :

select case when 
    max(field) keep (dense_rank first order by datfin desc nulls first) is null then 1 
    else 0 end as flag 
from MYTABLE;

Use the <sup></sup>tag (<sub></sub> is the equivalent for subscripts). See this gist for an example.

Wrap the multiple statements in a BEGIN END block to make them one statement and add a slash after the END; clause.

BEGIN
  insert into books
  (id, title, author)
  values
  (books_seq.nextval, 'The Bite in the Apple', 'Chrisann Brennan');

  insert into books
  (id, title, author)
  values
  (books_seq.nextval, 'The Restaurant at the End of the Universe', 'Douglas Adams');
END;
/

That way, it is just ctrl-a then ctrl-enter and it goes.

With Android Architecture Components through the use of LiveData this can be easily implemented with any type of Adapter. You simply have to do the following steps:

1. Setup your data to return from the Room Database as LiveData as in the example below:

@Dao
public interface CustomDAO{

@Query("SELECT * FROM words_table WHERE column LIKE :searchquery")
    public LiveData<List<Word>> searchFor(String searchquery);
}

2. Create a ViewModel object to update your data live through a method that will connect your DAO and your UI

public class CustomViewModel extends AndroidViewModel {

    private final AppDatabase mAppDatabase;

    public WordListViewModel(@NonNull Application application) {
        super(application);
        this.mAppDatabase = AppDatabase.getInstance(application.getApplicationContext());
    }

    public LiveData<List<Word>> searchQuery(String query) {
        return mAppDatabase.mWordDAO().searchFor(query);
    }

}

3. Call your data from the ViewModel on the fly by passing in the query through onQueryTextListener as below:

Inside onCreateOptionsMenu set your listener as follows

searchView.setOnQueryTextListener(onQueryTextListener);

Setup your query listener somewhere in your SearchActivity class as follows

private android.support.v7.widget.SearchView.OnQueryTextListener onQueryTextListener =
            new android.support.v7.widget.SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String query) {
                    getResults(query);
                    return true;
                }

                @Override
                public boolean onQueryTextChange(String newText) {
                    getResults(newText);
                    return true;
                }

                private void getResults(String newText) {
                    String queryText = "%" + newText + "%";
                    mCustomViewModel.searchQuery(queryText).observe(
                            SearchResultsActivity.this, new Observer<List<Word>>() {
                                @Override
                                public void onChanged(@Nullable List<Word> words) {
                                    if (words == null) return;
                                    searchAdapter.submitList(words);
                                }
                            });
                }
            };

Note: Steps (1.) and (2.) are standard AAC ViewModel and DAO implementation, the only real "magic" going on here is in the OnQueryTextListener which will update the results of your list dynamically as the query text changes.

If you need more clarification on the matter please don't hesitate to ask. I hope this helped :).

There's no primitive for this in C. I'd probably malloc (or perhaps alloca) a long enough buffer and loop over the input. I've also seen it done with a dynamic string library with semantics (but not syntax!) similar to C++'s ostringstream, which is a plausibly more generic solution but it may not be worth the extra complexity just for a single case.

if You are Using Toolbar the just Add

android:layout_gravity="center_horizontal"

Under the Toolbar Just like this snippet

 <android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@color/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay">

        <TextView
            android:id="@+id/tvTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"    //Important 
            android:textColor="@color/whitecolor"
            android:textSize="20sp"
            android:textStyle="bold" />
    </android.support.v7.widget.Toolbar>

</android.support.design.widget.AppBarLayout>

public string MakeRelativePath(string workingDirectory, string fullPath)
{
    string result = string.Empty;
    int offset;

    // this is the easy case.  The file is inside of the working directory.
    if( fullPath.StartsWith(workingDirectory) )
    {
        return fullPath.Substring(workingDirectory.Length + 1);
    }

    // the hard case has to back out of the working directory
    string[] baseDirs = workingDirectory.Split(new char[] { ':', '\\', '/' });
    string[] fileDirs = fullPath.Split(new char[] { ':', '\\', '/' });

    // if we failed to split (empty strings?) or the drive letter does not match
    if( baseDirs.Length <= 0 || fileDirs.Length <= 0 || baseDirs[0] != fileDirs[0] )
    {
        // can't create a relative path between separate harddrives/partitions.
        return fullPath;
    }

    // skip all leading directories that match
    for (offset = 1; offset < baseDirs.Length; offset++)
    {
        if (baseDirs[offset] != fileDirs[offset])
            break;
    }

    // back out of the working directory
    for (int i = 0; i < (baseDirs.Length - offset); i++)
    {
        result += "..\\";
    }

    // step into the file path
    for (int i = offset; i < fileDirs.Length-1; i++)
    {
        result += fileDirs[i] + "\\";
    }

    // append the file
    result += fileDirs[fileDirs.Length - 1];

    return result;
}

This code is probably not bullet-proof but this is what I came up with. It's a little more robust. It takes two paths and returns path B as relative to path A.

example:

MakeRelativePath("c:\\dev\\foo\\bar", "c:\\dev\\junk\\readme.txt")
//returns: "..\\..\\junk\\readme.txt"

MakeRelativePath("c:\\dev\\foo\\bar", "c:\\dev\\foo\\bar\\docs\\readme.txt")
//returns: "docs\\readme.txt"

<input type="file" onchange="getBaseUrl()">

function getBaseUrl ()  {
    var file = document.querySelector('input[type=file]')['files'][0];
    var reader = new FileReader();
    var baseString;
    reader.onloadend = function () {
        baseString = reader.result;
        console.log(baseString); 
    };
    reader.readAsDataURL(file);
}

The reason to make an App with no activity or service could be making a Homescreen Widget app that doesn't need to be started.
Once you start a project don't create any activities. After you created the project just hit run. Android studio will say No default activity found.

Click Edit Configuration (From the Run menu) and in the Launch option part set the Launch value to Nothing. Then click ok and run the App.

(Since there is no launcher activity, No app will be show in the Apps menu.).

Update (31/03/2019) : All icon themes work via Google Web Fonts now.

As pointed out by Edric, it's just a matter of adding the google web fonts link in your document's head now, like so:

<link href="https://fonts.googleapis.com/css?family=Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp" rel="stylesheet">

And then adding the correct class to output the icon of a particular theme.

<i class="material-icons">donut_small</i>
<i class="material-icons-outlined">donut_small</i>
<i class="material-icons-two-tone">donut_small</i>
<i class="material-icons-round">donut_small</i>
<i class="material-icons-sharp">donut_small</i>

The color of the icons can be changed using CSS as well.

Note: the Two-tone theme icons are a bit glitchy at present.

Update (14/11/2018) : List of 16 outline icons that work with the "_outline" suffix.

Here's the most recent list of 16 outline icons that work with the regular Material-icons Webfont, using the _outline suffix (tested and confirmed).

(As found on the material-design-icons github page. Search for: "_outline_24px.svg")

<i class="material-icons">help_outline</i>
<i class="material-icons">label_outline</i>
<i class="material-icons">mail_outline</i>
<i class="material-icons">info_outline</i>
<i class="material-icons">lock_outline</i>
<i class="material-icons">lightbulb_outline</i>
<i class="material-icons">play_circle_outline</i>
<i class="material-icons">error_outline</i>
<i class="material-icons">add_circle_outline</i>
<i class="material-icons">people_outline</i>
<i class="material-icons">person_outline</i>
<i class="material-icons">pause_circle_outline</i>
<i class="material-icons">chat_bubble_outline</i>
<i class="material-icons">remove_circle_outline</i>
<i class="material-icons">check_box_outline_blank</i>
<i class="material-icons">pie_chart_outlined</i>

Note that pie_chart needs to be "pie_chart_outlined" and not outline.

This is a hack to test out the new icon themes using an inline tag. It's not the official solution.

As of today (July 19, 2018), a little over 2 months since the new icons themes were introduced, there is No Way to include these icons using an inline tag <i class="material-icons"></i>.

+Martin has pointed out that there's an issue raised on Github regarding the same: https://github.com/google/material-design-icons/issues/773

So, until Google comes up with a solution for this, I've started using a hack to include these new icon themes in my development environment before downloading the appropriate icons as SVG or PNG. And I thought I'd share it with you all.

IMPORTANT: Do not use this on a production environment as each of the included CSS files from Google are over 1MB in size.

Google uses these stylesheets to showcase the icons on their demo page:

Outline:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/outline.css">

Rounded:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/round.css">

Two-Tone:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/twotone.css">

Sharp:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/sharp.css">

Each of these files contain the icons of the respective themes included as background-images (Base64 image-data). And here's how we can use this to test out the compatibility of a particular icon in our design before downloading it for use in the production environment.

STEP 1:

Include the stylesheet of the theme that you want to use. Eg: For the 'Outlined' theme, use the stylesheet for 'outline.css'

STEP 2:

Add the following classes to your own stylesheet:

.material-icons-new {
    display: inline-block;
    width: 24px;
    height: 24px;
    background-repeat: no-repeat;
    background-size: contain;
}

.icon-white {
    webkit-filter: contrast(4) invert(1);
    -moz-filter: contrast(4) invert(1);
    -o-filter: contrast(4) invert(1);
    -ms-filter: contrast(4) invert(1);
    filter: contrast(4) invert(1);
}

STEP 3:

Use the icon by adding the following classes to the <i> tag:

1. material-icons-new class

2. Icon name as shown on the material icons demo page, prefixed with the theme name followed by a hyphen.

Prefixes:

Outlined: outline-

Rounded: round-

Two-Tone: twotone-

Sharp: sharp-

Eg (for 'announcement' icon):

outline-announcement, round-announcement, twotone-announcement, sharp-announcement

3) Use an optional 3rd class icon-white for inverting the color from black to white (for dark backgrounds)

Changing icon size:

Since this is a background-image and not a font-icon, use the height and width properties of CSS to modify the size of the icons. The default is set to 24px in the material-icons-new class.

Example:

Case I: For the Outlined Theme of the account_circle icon:

1. Include the stylesheet:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/outline.css">

2. Add the icon tag on your page:

<i class="material-icons-new outline-account_circle"></i>

Optional (For dark backgrounds):

<i class="material-icons-new outline-account_circle icon-white"></i>

Case II: For the Sharp Theme of the assessment icon:

1. Include the stylesheet:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/sharp.css">

2. Add the icon tag on your page:

<i class="material-icons-new sharp-assessment"></i>

(For dark backgrounds):

<i class="material-icons-new sharp-assessment icon-white"></i>

I can't stress enough that this is NOT THE RIGHT WAY to include the icons on your production environment. But if you have to scan through multiple icons on your in-development page, it does make the icon inclusion pretty easy and saves a lot of time.

Downloading the icon as SVG or PNG sure is a better option when it comes to site-speed optimization, but font-icons are a time-saver when it comes to the prototyping phase and checking if a particular icon goes with your design, etc.

I will update this post if and when Google comes up with a solution for this issue that does not involve downloading an icon for usage.

<?php $data = "<div><p>Welcome to my PHP class, we are glad you are here</p></div>"; echo strip_tags($data); ?>

Or if you have a content coming from the database;

<?php $data = strip_tags($get_row['description']); ?> <?=substr($data, 0, 100) ?><?php if(strlen($data) > 100) { ?>...<?php } ?>

An algorithm is a self-contained step-by-step set of operations to be performed 4, typically interpreted as a finite sequence of (computer or human) instructions to determine a solution to a problem such as: is there a path from A to B, or what is the smallest path between A and B. In the latter case, you could also be satisfied with a 'reasonably close' alternative solution.

There are certain categories of algorithms, of which the heuristic algorithm is one. Depending on the (proven) properties of the algorithm in this case, it falls into one of these three categories (note 1):

• Exact: the solution is proven to be an optimal (or exact solution) to the input problem
• Approximation: the deviation of the solution value is proven to be never further away from the optimal value than some pre-defined bound (for example, never more than 50% larger than the optimal value)
• Heuristic: the algorithm has not been proven to be optimal, nor within a pre-defined bound of the optimal solution

Notice that an approximation algorithm is also a heuristic, but with the stronger property that there is a proven bound to the solution (value) it outputs.

For some problems, noone has ever found an 'efficient' algorithm to compute the optimal solutions (note 2). One of those problems is the well-known Traveling Salesman Problem. Christophides' algorithm for the Traveling Salesman Problem, for example, used to be called a heuristic, as it was not proven that it was within 50% of the optimal solution. Since it has been proven, however, Christophides' algorithm is more accurately referred to as an approximation algorithm.

Due to restrictions on what computers can do, it is not always possible to efficiently find the best solution possible. If there is enough structure in a problem, there may be an efficient way to traverse the solution space, even though the solution space is huge (i.e. in the shortest path problem).

Heuristics are typically applied to improve the running time of algorithms, by adding 'expert information' or 'educated guesses' to guide the search direction. In practice, a heuristic may also be a sub-routine for an optimal algorithm, to determine where to look first.

(note 1): Additionally, algorithms are characterised by whether they include random or non-deterministic elements. An algorithm that always executes the same way and produces the same answer, is called deterministic.

(note 2): This is called the P vs NP problem, and problems that are classified as NP-complete and NP-hard are unlikely to have an 'efficient' algorithm. Note; as @Kriss mentioned in the comments, there are even 'worse' types of problems, which may need exponential time or space to compute.

There are several answers that answer part of the question. I deemed them less complete and not accurate enough, and decided not to edit the accepted answer made by @Kriss

you can specify fields like this:

LOAD XML LOCAL INFILE '/pathtofile/file.xml' 
INTO TABLE my_tablename(personal_number, firstname, ...); 

Here's a reworking of your sample to get you started.

• your sample has a static event - it's more usual for an event to come from a class instance, but I've left it static below.

• the sample below also uses the more standard naming OnXxx for the method that raises the event.

• the sample below does not consider thread-safety, which may well be more of an issue if you insist on your event being static.

.

public enum MyEvents{ 
     Event1 
} 

public class MyEventArgs : EventArgs
{
    public MyEventArgs(MyEvents myEvents)
    {
        MyEvents = myEvents;
    }

    public MyEvents MyEvents { get; private set; }
}

public static class MyClass
{
     public static event EventHandler<MyEventArgs> EventTriggered; 

     public static void Trigger(MyEvents myEvents) 
     {
         OnMyEvent(new MyEventArgs(myEvents));
     }

     protected static void OnMyEvent(MyEventArgs e)
     {
         if (EventTriggered != null)
         {
             // Normally the first argument (sender) is "this" - but your example
             // uses a static event, so I'm passing null instead.
             // EventTriggered(this, e);
             EventTriggered(null, e);
         } 
     }
}

I wrote this little script that takes the guess work out of the copy/paste commands.

The Linux version of the script relies on xclip being already installed in your system. The script is called clipboard.

#!/bin/bash
# Linux version
# Use this script to pipe in/out of the clipboard
#
# Usage: someapp | clipboard     # Pipe someapp's output into clipboard
#        clipboard | someapp     # Pipe clipboard's content into someapp
#

if command -v xclip 1>/dev/null; then
    if [[ -p /dev/stdin ]] ; then
        # stdin is a pipe
        # stdin -> clipboard
        xclip -i -selection clipboard
    else
        # stdin is not a pipe
        # clipboard -> stdout
        xclip -o -selection clipboard
    fi
else
    echo "Remember to install xclip"
fi

The OS X version of the script relies on pbcopy and pbpaste which are preinstalled on all Macs.

#!/bin/bash
# OS X version
# Use this script to pipe in/out of the clipboard
#
# Usage: someapp | clipboard     # Pipe someapp's output into clipboard
#        clipboard | someapp     # Pipe clipboard's content into someapp
#

if [[ -p /dev/stdin ]] ; then
    # stdin is a pipe
    # stdin -> clipboard
    pbcopy
else
    # stdin is not a pipe
    # clipboard -> stdout
    pbpaste
fi

Using the script is very simple since you simply pipe in or out of clipboard as shown in these two examples.

$ cat file | clipboard

$ clipboard | less

The non-recursive version of the function is not too hard - here it is for integers:

long powi(long x, unsigned n)
{
    long p = x;
    long r = 1;

    while (n > 0)
    {
        if (n % 2 == 1)
            r *= p;
        p *= p;
        n /= 2;
    }

    return(r);
}

(Hacked out of code for raising a double value to an integer power - had to remove the code to deal with reciprocals, for example.)

Jumping off from Alex Montoya's approach for multiple file input elements

const inputFiles = document.querySelectorAll('input[type="file"]');
const formData = new FormData();

for (const file of inputFiles) {
    formData.append(file.name, file.files[0]);
}

fetch(url, {
    method: 'POST',
    body: formData })

The problem with writing scripts at the head of a page is blocking. The browser must stop processing the page until the script is download, parsed and executed. The reason for this is pretty clear, these scripts might insert more into the page changing the result of the rendering, they also may remove things that dont need to be rendered, etc.

Some of the more modern browsers violate this rule by not blocking on the downloading the scripts (ie8 was the first) but overall the download isn't the majority of the time spent blocking.

Check out Even Faster Websites, I just finished reading it and it goes over all of the fast ways to get scripts onto a page, Including putting scripts at the bottom of the page to allow rendering to complete (better UX).

I assumed openjdk8 would work with tomcat8 but I had to remove it and keep openjdk7 only, this fixed the issue in my case. I really don't know why or if there is something else I could have done.

Use set Parameter from query.

Query q = (Query) em.createNativeQuery("SELECT count(*) FROM mytable where username = ?1");
q.setParameter(1, "test");

If one want to keep getting updated processes (on the example, 2 seconds) on a shell session without having to manually interact with it use:

watch -n 2 'mysql -h 127.0.0.1 -P 3306 -u some_user -psome_pass some_database -e "show full processlist;"'

The only bad thing about the show [full] processlist is that you can't filter the output result. On the other hand, issuing the SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST open possibilities to remove from the output anything you don't want to see:

SELECT * from INFORMATION_SCHEMA.PROCESSLIST
WHERE DB = 'somedatabase'
AND COMMAND <> 'Sleep'
AND HOST NOT LIKE '10.164.25.133%' \G

array_merge is the elegant way:

$a = array('a', 'b');
$b = array('c', 'd');
$merge = array_merge($a, $b); 
// $merge is now equals to array('a','b','c','d');

Doing something like:

$merge = $a + $b;
// $merge now equals array('a','b')

Will not work, because the + operator does not actually merge them. If they $a has the same keys as $b, it won't do anything.

There is no "right way". If you want a universal (but suboptimal) solution you can use a boost::lexical cast.

A common solution for C++ is to use std::ostream and << operator. You can use a stringstream and stringstream::str() method for conversion to string.

If you really require a fast mechanism (remember the 20/80 rule) you can look for a "dedicated" solution like C++ String Toolkit Library

For the JS, try

data: {id: the_id}
...
success: function(data) {
        alert('the server returned ' + data;
    }

and

$the_id = intval($_POST['id']);

in PHP

In Swift 5

Using this implementation you just have to give epoch time as a parameter and you will the output as (1 second ago, 2 minutes ago, and so on).

func setTimestamp(epochTime: String) -> String {
    let currentDate = Date()
    let epochDate = Date(timeIntervalSince1970: TimeInterval(epochTime) as! TimeInterval)

    let calendar = Calendar.current

    let currentDay = calendar.component(.day, from: currentDate)
    let currentHour = calendar.component(.hour, from: currentDate)
    let currentMinutes = calendar.component(.minute, from: currentDate)
    let currentSeconds = calendar.component(.second, from: currentDate)

    let epochDay = calendar.component(.day, from: epochDate)
    let epochMonth = calendar.component(.month, from: epochDate)
    let epochYear = calendar.component(.year, from: epochDate)
    let epochHour = calendar.component(.hour, from: epochDate)
    let epochMinutes = calendar.component(.minute, from: epochDate)
    let epochSeconds = calendar.component(.second, from: epochDate)

    if (currentDay - epochDay < 30) {
        if (currentDay == epochDay) {
            if (currentHour - epochHour == 0) {
                if (currentMinutes - epochMinutes == 0) {
                    if (currentSeconds - epochSeconds <= 1) {
                        return String(currentSeconds - epochSeconds) + " second ago"
                    } else {
                        return String(currentSeconds - epochSeconds) + " seconds ago"
                    }

                } else if (currentMinutes - epochMinutes <= 1) {
                    return String(currentMinutes - epochMinutes) + " minute ago"
                } else {
                    return String(currentMinutes - epochMinutes) + " minutes ago"
                }
            } else if (currentHour - epochHour <= 1) {
                return String(currentHour - epochHour) + " hour ago"
            } else {
                return String(currentHour - epochHour) + " hours ago"
            }
        } else if (currentDay - epochDay <= 1) {
            return String(currentDay - epochDay) + " day ago"
        } else {
            return String(currentDay - epochDay) + " days ago"
        }
    } else {
        return String(epochDay) + " " + getMonthNameFromInt(month: epochMonth) + " " + String(epochYear)
    }
}


func getMonthNameFromInt(month: Int) -> String {
    switch month {
    case 1:
        return "Jan"
    case 2:
        return "Feb"
    case 3:
        return "Mar"
    case 4:
        return "Apr"
    case 5:
        return "May"
    case 6:
        return "Jun"
    case 7:
        return "Jul"
    case 8:
        return "Aug"
    case 9:
        return "Sept"
    case 10:
        return "Oct"
    case 11:
        return "Nov"
    case 12:
        return "Dec"
    default:
        return ""
    }
}

How to call?

setTimestamp(epochTime: time) and you'll get the desired output as a string.

Just for fun, a solution using the jsr166y fork-join framework that should in JDK7.

import java.util.concurrent.forkjoin.*;

private final ForkJoinExecutor executor = new ForkJoinPool();
...
List<Integer> ints = ...;
List<String> strs =
    ParallelArray.create(ints.size(), Integer.class, executor)
    .withMapping(new Ops.Op<Integer,String>() { public String op(Integer i) {
        return String.valueOf(i);
    }})
    .all()
    .asList();

(Disclaimer: Not compiled. Spec is not finalised. Etc.)

Unlikely to be in JDK7 is a bit of type inference and syntactical sugar to make that withMapping call less verbose:

    .withMapping(#(Integer i) String.valueOf(i))

I think concat is a nice way to do this. If they are present it uses the name attributes of the Series as the columns (otherwise it simply numbers them):

In [1]: s1 = pd.Series([1, 2], index=['A', 'B'], name='s1')

In [2]: s2 = pd.Series([3, 4], index=['A', 'B'], name='s2')

In [3]: pd.concat([s1, s2], axis=1)
Out[3]:
   s1  s2
A   1   3
B   2   4

In [4]: pd.concat([s1, s2], axis=1).reset_index()
Out[4]:
  index  s1  s2
0     A   1   3
1     B   2   4

Note: This extends to more than 2 Series.

var FD = new System.Windows.Forms.OpenFileDialog();
if (FD.ShowDialog() == System.Windows.Forms.DialogResult.OK) {
    string fileToOpen = FD.FileName;

    System.IO.FileInfo File = new System.IO.FileInfo(FD.FileName);

    //OR

    System.IO.StreamReader reader = new System.IO.StreamReader(fileToOpen);
    //etc
}

First string date is converted to js date format and converted into string format again, then it is compared with original string.

function dateValidation(){
    var dateString = "34/05/2019"
    var dateParts = dateString.split("/");
    var date= new Date(+dateParts[2], dateParts[1] - 1, +dateParts[0]);

    var isValid = isValid( dateString, date );
    console.log("Is valid date: " + isValid);
}

function isValidDate(dateString, date) {
    var newDateString = ( date.getDate()<10 ? ('0'+date.getDate()) : date.getDate() )+ '/'+ ((date.getMonth() + 1)<10? ('0'+(date.getMonth() + 1)) : (date.getMonth() + 1) )  + '/' +  date.getFullYear();
    return ( dateString == newDateString);
}

For saving Current time to firebase database I use Unic Epoch Conversation:

let timestamp = NSDate().timeIntervalSince1970

and For Decoding Unix Epoch time to Date().

let myTimeInterval = TimeInterval(timestamp)
let time = NSDate(timeIntervalSince1970: TimeInterval(myTimeInterval))

You can not create URI from resources inside of the jar file. You can simply write it to the temp file and then use it (java8):

Path path = File.createTempFile("some", "address").toPath();
Files.copy(ClassLoader.getSystemResourceAsStream("/path/to/resource"), path, StandardCopyOption.REPLACE_EXISTING);

For python 3

import datetime
now = datetime.datetime.now()
print(now.year, now.month, now.day, now.hour, now.minute, now.second)

Check out this URL. It is working perfectly for the requirement.

Thanks a lot to the author. For quick reference I pasted the main logic below:

var scripts = document.getElementsByTagName('script');
var myScript = scripts[ scripts.length - 1 ];

var queryString = myScript.src.replace(/^[^\?]+\??/,'');

var params = parseQuery( queryString );

function parseQuery ( query ) {
  var Params = new Object ();
  if ( ! query ) return Params; // return empty object
  var Pairs = query.split(/[;&]/);
  for ( var i = 0; i < Pairs.length; i++ ) {
    var KeyVal = Pairs[i].split('=');
    if ( ! KeyVal || KeyVal.length != 2 ) continue;
    var key = unescape( KeyVal[0] );
    var val = unescape( KeyVal[1] );
    val = val.replace(/\+/g, ' ');
    Params[key] = val;
  }
  return Params;
}

It's said here that you should be able to add the following to your chart config:

  credits: {

that will remove the "Highcharts.com" text from the bottom of the chart.

This worked for me:

$('input[name="sort_order"]').attr('value','XXX');

Use ngInit: https://docs.angularjs.org/api/ng/directive/ngInit

  Temperature: {{f.temperature}}<br>
  Humidity: {{f.humidity}}<br>
  ...

I think you just have incorrect casing in the format string. According to the documentation this should work for you: MM/DD/YYYY

moment.js documentation

using padding pad

In order to move the colorbar relative to the subplot, one may use the pad argument to fig.colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, orientation="horizontal", pad=0.2)
plt.show()

using an axes divider

One can use an instance of make_axes_locatable to divide the axes and create a new axes which is perfectly aligned to the image plot. Again, the pad argument would allow to set the space between the two axes.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

divider = make_axes_locatable(ax)
cax = divider.new_vertical(size="5%", pad=0.7, pack_start=True)
fig.add_axes(cax)
fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

using subplots

One can directly create two rows of subplots, one for the image and one for the colorbar. Then, setting the height_ratios as gridspec_kw={"height_ratios":[1, 0.05]} in the figure creation, makes one of the subplots much smaller in height than the other and this small subplot can host the colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, (ax, cax) = plt.subplots(nrows=2,figsize=(4,4), 
                  gridspec_kw={"height_ratios":[1, 0.05]})
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

In the first two cases, you simply forgot to actually call the member function (!, it's not a value) std::vector<int>::size like this:

#include <vector>

int main () {
    std::vector<int> v;
    auto size = v.size();
}

Your third call

int size = v.size();

triggers a warning, as not every return value of that function (usually a 64 bit unsigned int) can be represented as a 32 bit signed int.

int size = static_cast<int>(v.size());

would always compile cleanly and also explicitly states that your conversion from std::vector::size_type to int was intended.

Note that if the size of the vector is greater than the biggest number an int can represent, size will contain an implementation defined (de facto garbage) value.

This solution is not an apt one, but serves purpose in some occasions.

First create a folder and add it to your system path. Go to the executable of whatever program you want to create alias for. Right click and send to Desktop( Create Shortcut). Rename the shortcut to whatever alias name is comfortable. Now, take the shortcut and place in your folder.

From run prompt you can type the shortcut name directly and you can have the program opened for you. But from command prompt, you need to append .lnk and hit enter, the program will be opened.

For your example, this will do the magic in Java 8

List<Double> testList = new ArrayList();
testList.sort(Comparator.naturalOrder());

But if you want to sort by some of the fields of the object you are sorting, you can do it easily by:

testList.sort(Comparator.comparing(ClassName::getFieldName));

or

 testList.sort(Comparator.comparing(ClassName::getFieldName).reversed());

or

 testList.stream().sorted(Comparator.comparing(ClassName::getFieldName).reversed()).collect(Collectors.toList());

Adding on to the one mentioned by @abarnert

a better one is to catch the exception

import subprocess
try:
    py2output = subprocess.check_output(['python', 'py2.py', '-i', 'test.txt'],stderr= subprocess.STDOUT)  
    #print('py2 said:', py2output)
    print "here"
except subprocess.CalledProcessError as e:
    print "Calledprocerr"

this stderr= subprocess.STDOUT is for making sure you dont get the filenotfound error in stderr- which cant be usually caught in filenotfoundexception, else you would end up getting

python: can't open file 'py2.py': [Errno 2] No such file or directory

Infact a better solution to this might be to check, whether the file/scripts exist and then to run the file/script

Nothing can be more simple than this

#include <stdio.h>  

int main()  
{  
    int i;  

    for( i=0 ; i<=255 ; i++ ) /*ASCII values ranges from 0-255*/  
    {  
        printf("ASCII value of character %c = %d\n", i, i);  
    }  

    return 0;  
}   

Source: program to print ASCII value of all characters

select MAX(Salary) from Employee WHERE Salary NOT IN (select MAX(Salary) from Employee );

You can use boost::optional (or std::optional for newer versions), which was developed in particular for decision of your problem:

boost::optional<int> y[50];
....
geoGraph.y[x] = nums[x];
....
const size_t size_y = sizeof(y)/sizeof(y[0]); //!!!! correct size of y!!!!
for(int i=0; i<size_y;i++){
   if(y[i]) { //check for null
      p[i].SetPoint(Recto.Height()-x,*y[i]);
      ....
   }
}

P.S. Do not use C-type array -> use std::array or std::vector:

std::array<int, 50> y;   //not int y[50] !!!

System.out.println("Managers choice this week" + anyItem + "our recommendation to you");

You havent the variable anyItem initialized or even declared.

This code: + anyItem +

means get value of toString method of Object anyItem

The second thing why this wont work. You have System.out.print after return statement. Program could never reach tha line.

You probably want something like:

public Item anyItem() {
    int index = randomGenerator.nextInt(catalogue.size());
    System.out.println("Managers choice this week" + catalogue.get(index) + "our recommendation to you");
    return catalogue.get(index);

}

btw: in Java its convetion to place the curly parenthesis on the same line as the declaration of the function.

To include native libraries you need:

1. create "jar" file with special structure containing ".so" files;
2. include that file in dependencies list.

To create jar file, use the following snippet:

task nativeLibsToJar(type: Zip, description: 'create a jar archive of the native libs') {
    destinationDir file("$buildDir/native-libs")
    baseName 'native-libs'
    extension 'jar'
    from fileTree(dir: 'libs', include: '**/*.so')
    into 'lib/'
}

tasks.withType(Compile) {
    compileTask -> compileTask.dependsOn(nativeLibsToJar)
}

To include resulting file, paste the following line into "dependencies" section in "build.gradle" file:

compile fileTree(dir: "$buildDir/native-libs", include: 'native-libs.jar')

Here's a method I wrote to check if an URL exists or not. I had a requirement to add a request header. It's Groovy but should be fairly simple to adapt to Java. Essentially I'm using the org.springframework.web.client.RestTemplate#execute(java.lang.String, org.springframework.http.HttpMethod, org.springframework.web.client.RequestCallback, org.springframework.web.client.ResponseExtractor<T>, java.lang.Object...) API method. I guess the solution you arrive at depends at least in part on the HTTP method you want to execute. The key take away from example below is that I'm passing a Groovy closure (The third parameter to method restTemplate.execute(), which is more or less, loosely speaking a Lambda in Java world) that is executed by the Spring API as a callback to be able to manipulate the request object before Spring executes the command,

boolean isUrlExists(String url) {
    try {
      return (restTemplate.execute(url, HttpMethod.HEAD,
              { ClientHttpRequest request -> request.headers.add('header-name', 'header-value') },
              { ClientHttpResponse response -> response.headers }) as HttpHeaders)?.get('some-response-header-name')?.contains('some-response-header-value')
    } catch (Exception e) {
      log.warn("Problem checking if $url exists", e)
    }
    false
  }

I think you want $data[$category] = $question;

Or in case you want an array that maps categories to array of questions:

$data = array();
foreach($file_data as $value) {
    list($category, $question) = explode('|', $value, 2);

    if(!isset($data[$category])) {
        $data[$category] = array();
    }
    $data[$category][] = $question;
}
print_r($data);

Based on @ZakTaccardi's answer, and assuming you don't want a single project for both flavors, add this to the end of your build.gradle file:

def appModuleRootFolder = '.'
def srcDir = 'src'
def googleServicesJson = 'google-services.json'

task switchToStaging(type: Copy) {
    outputs.upToDateWhen { false }
    def flavor = 'staging'
    description = "Switches to $flavor $googleServicesJson"
    delete "$appModuleRootFolder/$googleServicesJson"
    from "${srcDir}/$flavor/"
    include "$googleServicesJson"
    into "$appModuleRootFolder"
}

task switchToProduction(type: Copy) {
    outputs.upToDateWhen { false }
    def flavor = 'production'
    description = "Switches to $flavor $googleServicesJson"
    from "${srcDir}/$flavor/"
    include "$googleServicesJson"
    into "$appModuleRootFolder"
}

afterEvaluate {
    processStagingDebugGoogleServices.dependsOn switchToStaging
    processStagingReleaseGoogleServices.dependsOn switchToStaging
    processProductionDebugGoogleServices.dependsOn switchToProduction
    processProductionReleaseGoogleServices.dependsOn switchToProduction
}

You need to have the files src/staging/google-services.json and src/production/google-services.json. Replace the flavor names for the ones you use.

You can just add the DISTINCT(ip), but it has to come at the start of the query. Be sure to escape PHP variables that go into the SQL string.

SELECT DISTINCT(ip), name, COUNT(name) nameCnt, 
time, price, SUM(price) priceSum
FROM tablename 
WHERE time >= $yesterday AND time <$today 
GROUP BY ip, name

What's a C++ reference (for C programmers)

A reference can be thought of as a constant pointer (not to be confused with a pointer to a constant value!) with automatic indirection, ie the compiler will apply the * operator for you.

All references must be initialized with a non-null value or compilation will fail. It's neither possible to get the address of a reference - the address operator will return the address of the referenced value instead - nor is it possible to do arithmetics on references.

C programmers might dislike C++ references as it will no longer be obvious when indirection happens or if an argument gets passed by value or by pointer without looking at function signatures.

C++ programmers might dislike using pointers as they are considered unsafe - although references aren't really any safer than constant pointers except in the most trivial cases - lack the convenience of automatic indirection and carry a different semantic connotation.

Consider the following statement from the C++ FAQ:

Even though a reference is often implemented using an address in the underlying assembly language, please do not think of a reference as a funny looking pointer to an object. A reference is the object. It is not a pointer to the object, nor a copy of the object. It is the object.

But if a reference really were the object, how could there be dangling references? In unmanaged languages, it's impossible for references to be any 'safer' than pointers - there generally just isn't a way to reliably alias values across scope boundaries!

Why I consider C++ references useful

Coming from a C background, C++ references may look like a somewhat silly concept, but one should still use them instead of pointers where possible: Automatic indirection is convenient, and references become especially useful when dealing with RAII - but not because of any perceived safety advantage, but rather because they make writing idiomatic code less awkward.

RAII is one of the central concepts of C++, but it interacts non-trivially with copying semantics. Passing objects by reference avoids these issues as no copying is involved. If references were not present in the language, you'd have to use pointers instead, which are more cumbersome to use, thus violating the language design principle that the best-practice solution should be easier than the alternatives.

The File.Create method creates the file and opens a FileStream on the file. So your file is already open. You don't really need the file.Create method at all:

string filePath = @"c:\somefilename.txt";
using (StreamWriter sw = new StreamWriter(filePath, true))
{
    //write to the file
}

The boolean in the StreamWriter constructor will cause the contents to be appended if the file exists.

If you are using approach with class-based views and different 'action' attrs i mean

Put different URLs in the action for the two forms. Then you'll have two different view functions to deal with the two different forms.

You can easily handle errors from different forms using overloaded get_context_data method, e.x:

views.py:

class LoginView(FormView):
    form_class = AuthFormEdited
    success_url = '/'
    template_name = 'main/index.html'

    def dispatch(self, request, *args, **kwargs):
        return super(LoginView, self).dispatch(request, *args, **kwargs)

    ....

    def get_context_data(self, **kwargs):
        context = super(LoginView, self).get_context_data(**kwargs)
        context['login_view_in_action'] = True
        return context

class SignInView(FormView):
    form_class = SignInForm
    success_url = '/'
    template_name = 'main/index.html'

    def dispatch(self, request, *args, **kwargs):
        return super(SignInView, self).dispatch(request, *args, **kwargs)

    .....

    def get_context_data(self, **kwargs):
        context = super(SignInView, self).get_context_data(**kwargs)
        context['login_view_in_action'] = False
        return context

template:

<div class="login-form">
<form action="/login/" method="post" role="form">
    {% csrf_token %}
    {% if login_view_in_action %}
        {% for e in form.non_field_errors %}
            <div class="alert alert-danger alert-dismissable">
                {{ e }}
                <a class="panel-close close" data-dismiss="alert">×</a>
            </div>
        {% endfor %}
    {% endif %}
    .....
    </form>
</div>

<div class="signin-form">
<form action="/registration/" method="post" role="form">
    {% csrf_token %}
    {% if not login_view_in_action %}
        {% for e in form.non_field_errors %}
            <div class="alert alert-danger alert-dismissable">
                {{ e }}
                <a class="panel-close close" data-dismiss="alert">×</a>

I thought I'd try code this up for fun:

        '1': ['2', '3', '4'],
        '2': ['5', '6'],
        '5': ['9', '10'],
        '4': ['7', '8'],
        '7': ['11', '12']
        }

def bfs(graph, forefront, end):
    # assumes no cycles

    next_forefront = [(node, path + ',' + node) for i, path in forefront if i in graph for node in graph[i]]

    for node,path in next_forefront:
        if node==end:
            return path
    else:
        return bfs(graph,next_forefront,end)

print bfs(graph,[('1','1')],'11')

# 1, 4, 7, 11

If you want cycles you could add this:

for i, j in for_front: # allow cycles, add this code
    if i in graph:
        del graph[i]

To permanently delete the previous commands, use this

1. Set-PSReadlineOption -HistoryNoDuplicates

2. Remove-Item (Get-PSReadlineOption).HistorySavePath

3. Alt-f7

I'm with Will:

• Double quotes for text
• Single quotes for anything that behaves like an identifier
• Double quoted raw string literals for regexps
• Tripled double quotes for docstrings

I'll stick with that even if it means a lot of escaping.

I get the most value out of single quoted identifiers standing out because of the quotes. The rest of the practices are there just to give those single quoted identifiers some standing room.

The openssl documentation says that file supplied as the -in argument must be in PEM format.

Turns out that, contrary to the CA's manual, the certificate returned by the CA which I stored in myCert.cer is not PEM format rather it is PKCS7.

In order to create my .p12, I had to first convert the certificate to PEM:

openssl pkcs7 -in myCert.cer -print_certs -out certs.pem

and then execute

openssl pkcs12 -export -out keyStore.p12 -inkey myKey.pem -in certs.pem

}

We can easily do that in css3. We have to simply use @import statement. The following video easily describes the way how to do that. so go ahead and watch it out.
