Single line swapping

a = a^b^(b^=(a^b));

To help everyone avoid confusion, I will reformulate the question in two parts.

First : "how can make an authenticated HTTP request with a browser, using BASIC auth?".

In the browser you can do a http basic auth first by waiting the prompt to come, or by editing the URL if you follow this format: http://myusername:[email protected]

NB: the curl command mentionned in the question is perfectly fine, if you have a command-line and curl installed. ;)

References:

• https://en.wikipedia.org/wiki/Basic_access_authentication#URL_encoding
• https://en.wikipedia.org/wiki/Uniform_Resource_Locator#Syntax
• https://tools.ietf.org/html/rfc3986#page-18

Also according to the CURL manual page https://curl.haxx.se/docs/manual.html

HTTP

  Curl also supports user and password in HTTP URLs, thus you can pick a file
  like:

      curl http://name:[email protected]/full/path/to/file

  or specify user and password separately like in

      curl -u name:passwd http://machine.domain/full/path/to/file

  HTTP offers many different methods of authentication and curl supports
  several: Basic, Digest, NTLM and Negotiate (SPNEGO). Without telling which
  method to use, curl defaults to Basic. You can also ask curl to pick the
  most secure ones out of the ones that the server accepts for the given URL,
  by using --anyauth.

  NOTE! According to the URL specification, HTTP URLs can not contain a user
  and password, so that style will not work when using curl via a proxy, even
  though curl allows it at other times. When using a proxy, you _must_ use
  the -u style for user and password.

The second and real question is "However, on somesite.com, I'm not getting an authorization prompt at all, just a page that says I'm not authorized. Did somesite not implement the Basic Auth workflow correctly, or is there something else I need to do?"

The curl documentation says the -u option supports many method of authentication, Basic being the default.

Parse error: syntax error, unexpected '['

This error comes in two variatians:

Variation 1

$arr = [1, 2, 3];

This array initializer syntax was only introduced in PHP 5.4; it will raise a parser error on versions before that. If possible, upgrade your installation or use the old syntax:

$arr = array(1, 2, 3);

See also this example from the manual.

Variation 2

$suffix = explode(',', 'foo,bar')[1];

Array dereferencing function results was also introduced in PHP 5.4. If it's not possible to upgrade you need to use a (temporary) variable:

$parts = explode(',', 'foo,bar');
$suffix = $parts[1];

See also this example from the manual.

Make sure that you alter the system and enable restricted session before you kill them or they will quickly log back into the database before you get your work completed.

In conf/hdfs-site.xml, you should have a property like

<property>
    <name>dfs.name.dir</name>
    <value>/home/user/hadoop/name/data</value>
</property>

The property "dfs.name.dir" allows you to control where Hadoop writes NameNode metadata. And giving it another dir rather than /tmp makes sure the NameNode data isn't being deleted when you reboot.

The wildcard library efficiently does both glob and regex filename matching:

http://code.google.com/p/wildcard/

The implementation is succinct -- JAR is only 12.9 kilobytes.

Data validation drop down

There is a list option in Data validation. If this is combined with a VLOOKUP formula you would be able to convert the selected value into a number.

The steps in Excel 2010 are:

• Create your list with matching values.
• On the Data tab choose Data Validation
• The Data validation form will be displayed
• Set the Allow dropdown to List
• Set the Source range to the first part of your list
• Click on OK (User messages can be added if required)

In a cell enter a formula like this

=VLOOKUP(A2,$D$3:$E$5,2,FALSE)

which will return the matching value from the second part of your list.

Form control drop down

Alternatively, Form controls can be placed on a worksheet. They can be linked to a range and return the position number of the selected value to a specific cell.

The steps in Excel 2010 are:

• Create your list of data in a worksheet
• Click on the Developer tab and dropdown on the Insert option
• In the Form section choose Combo box or List box
• Use the mouse to draw the box on the worksheet
• Right click on the box and select Format control
• The Format control form will be displayed
• Click on the Control tab
• Set the Input range to your list of data
• Set the Cell link range to the cell where you want the number of the selected item to appear
• Click on OK

You can rearrange columns directly by specifying their order:

df = df[['a', 'y', 'b', 'x']]

In the case of larger dataframes where the column titles are dynamic, you can use a list comprehension to select every column not in your target set and then append the target set to the end.

>>> df[[c for c in df if c not in ['b', 'x']] 
       + ['b', 'x']]
   a  y  b   x
0  1 -1  2   3
1  2 -2  4   6
2  3 -3  6   9
3  4 -4  8  12

To make it more bullet proof, you can ensure that your target columns are indeed in the dataframe:

cols_at_end = ['b', 'x']
df = df[[c for c in df if c not in cols_at_end] 
        + [c for c in cols_at_end if c in df]]

If your tags are sortable using the linux sort command, use this:

git tag | sort -n | tail -1

eg. if git tag returns:

v1.0.1
v1.0.2
v1.0.5
v1.0.4

git tag | sort -n | tail -1 will output:

v1.0.5

git tag | sort -n | tail -2 | head -1 will output:

v1.0.4

(because you asked for the second most recent tag)

to checkout the tag, first clone the repo, then type:

git checkout v1.0.4

..or whatever tag you need.

In Angular 2 and above, “everything is a component.” Components are the main way we build and specify elements and logic on the page, through both custom elements and attributes that add functionality to our existing components.

http://learnangular2.com/components/

But what directives do then in Angular2+ ?

Attribute directives attach behaviour to elements.

There are three kinds of directives in Angular:

1. Components—directives with a template.
2. Structural directives—change the DOM layout by adding and removing DOM elements.
3. Attribute directives—change the appearance or behaviour of an element, component, or another directive.

https://angular.io/docs/ts/latest/guide/attribute-directives.html

So what's happening in Angular2 and above is Directives are attributes which add functionalities to elements and components.

Look at the sample below from Angular.io:

import { Directive, ElementRef, Input } from '@angular/core';

@Directive({ selector: '[myHighlight]' })
export class HighlightDirective {
    constructor(el: ElementRef) {
       el.nativeElement.style.backgroundColor = 'yellow';
    }
}

So what it does, it will extends you components and HTML elements with adding yellow background and you can use it as below:

<p myHighlight>Highlight me!</p>

But components will create full elements with all functionalities like below:

import { Component } from '@angular/core';

@Component({
  selector: 'my-component',
  template: `
    <div>Hello my name is {{name}}. 
      <button (click)="sayMyName()">Say my name</button>
    </div>
   `
})
export class MyComponent {
  name: string;
  constructor() {
    this.name = 'Alireza'
  }
  sayMyName() {
    console.log('My name is', this.name)
  }
}

and you can use it as below:

<my-component></my-component>

When we use the tag in the HTML, this component will be created and the constructor get called and rendered.

Try inserting <xsl:number format="1. "/><xsl:value-of select="."/><xsl:text> in the place of ???.

Note the "1. " - this is the number format. More info: here

For me that function worked:

private static JSONObject concatJSONS(JSONObject json, JSONObject obj) {
    JSONObject result = new JSONObject();

    for(Object key: json.keySet()) {
        System.out.println("adding " + key + " to result json");
        result.put(key, json.get(key));
    }

    for(Object key: obj.keySet()) {
        System.out.println("adding " + key + " to result json");
        result.put(key, obj.get(key));
    }

    return result;
}

(notice) - this implementation of concataion of json is for import org.json.simple.JSONObject;

Add the key View controller-based status bar appearance to Info.plist file and make it boolean type set to NO.

Insert one line code in viewDidLoad (this works on specific class where it is mentioned)

 [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

So I created an account just so I could help fix this problem that is plaguing a lot of people and where the fixes above aren't working.

If you get this error and nothing here helps. Try clicking the "Resume program play button" until the program finishes past the error. Then click in the console tab next to debug and read the red text.

I was getting that source code error even though my issue was trying to insert a value into a null Array. Step 1 Click the resume button

Step 2 Click the console tab and read the red text

In newer versions of matplotlib, if you do not set the tick labels with a bunch of str values, they are '' by default (and when the plot is draw the labels are simply the ticks values). Knowing that, to get your desired output would require something like this:

>>> from pylab import *
>>> axes = figure().add_subplot(111)
>>> a=axes.get_xticks().tolist()
>>> a[1]='change'
>>> axes.set_xticklabels(a)
[<matplotlib.text.Text object at 0x539aa50>, <matplotlib.text.Text object at 0x53a0c90>, 
<matplotlib.text.Text object at 0x53a73d0>, <matplotlib.text.Text object at 0x53a7a50>, 
<matplotlib.text.Text object at 0x53aa110>, <matplotlib.text.Text object at 0x53aa790>]
>>> plt.show()

and the result:

and now if you check the _xticklabels, they are no longer a bunch of ''.

>>> [item.get_text() for item in axes.get_xticklabels()]
['0.0', 'change', '1.0', '1.5', '2.0']

It works in the versions from 1.1.1rc1 to the current version 2.0.

This is my easiest solution:

public IActionResult InfoTag()
{
    return Ok(new {name = "Fabio", age = 42, gender = "M"});
}

or

public IActionResult InfoTag()
{
    return Json(new {name = "Fabio", age = 42, gender = "M"});
}

I also stumbled over this problem recently. Here is my solution. I wanted to avoid recursion, so I used a while loop.

Because of the adds and removes in arbitrary places on the list, I went with the LinkedList implementation.

/* traverses tree starting with given node */
  private static List<Node> traverse(Node n)
  {
    return traverse(Arrays.asList(n));
  }

  /* traverses tree starting with given nodes */
  private static List<Node> traverse(List<Node> nodes)
  {
    List<Node> open = new LinkedList<Node>(nodes);
    List<Node> visited = new LinkedList<Node>();

    ListIterator<Node> it = open.listIterator();
    while (it.hasNext() || it.hasPrevious())
    {
      Node unvisited;
      if (it.hasNext())
        unvisited = it.next();
      else
        unvisited = it.previous();

      it.remove();

      List<Node> children = getChildren(unvisited);
      for (Node child : children)
        it.add(child);

      visited.add(unvisited);
    }

    return visited;
  }

  private static List<Node> getChildren(Node n)
  {
    List<Node> children = asList(n.getChildNodes());
    Iterator<Node> it = children.iterator();
    while (it.hasNext())
      if (it.next().getNodeType() != Node.ELEMENT_NODE)
        it.remove();
    return children;
  }

  private static List<Node> asList(NodeList nodes)
  {
    List<Node> list = new ArrayList<Node>(nodes.getLength());
    for (int i = 0, l = nodes.getLength(); i < l; i++)
      list.add(nodes.item(i));
    return list;
  }

There are many answers to this already, but I think this approach is the most clean implementation:

def quicksort(arr):
    """ Quicksort a list

    :type arr: list
    :param arr: List to sort
    :returns: list -- Sorted list
    """
    if not arr:
        return []

    pivots = [x for x in arr if x == arr[0]]
    lesser = quicksort([x for x in arr if x < arr[0]])
    greater = quicksort([x for x in arr if x > arr[0]])

    return lesser + pivots + greater

You can of course skip storing everything in variables and return them straight away like this:

def quicksort(arr):
    """ Quicksort a list

    :type arr: list
    :param arr: List to sort
    :returns: list -- Sorted list
    """
    if not arr:
        return []

    return quicksort([x for x in arr if x < arr[0]]) \
        + [x for x in arr if x == arr[0]] \
        + quicksort([x for x in arr if x > arr[0]])

As an addition to mklement0's excellent answer:

Almost all executables accept \" as an escaped ". Safe usage in cmd however is almost only possible using DELAYEDEXPANSION.
To explicitely send a literal " to some process, assign \" to an environment variable, and then use that variable, whenever you need to pass a quote. Example:

SETLOCAL ENABLEDELAYEDEXPANSION
set q=\"
child "malicious argument!q!&whoami"

Note SETLOCAL ENABLEDELAYEDEXPANSION seems to work only within batch files. To get DELAYEDEXPANSION in an interactive session, start cmd /V:ON.

If your batchfile does't work with DELAYEDEXPANSION, you can enable it temporarily:

::region without DELAYEDEXPANSION

SETLOCAL ENABLEDELAYEDEXPANSION
::region with DELAYEDEXPANSION
set q=\"
echoarg.exe "ab !q! & echo danger"
ENDLOCAL

::region without DELAYEDEXPANSION

If you want to pass dynamic content from a variable that contains quotes that are escaped as "" you can replace "" with \" on expansion:

SETLOCAL ENABLEDELAYEDEXPANSION
foo.exe "danger & bar=region with !dynamic_content:""=\"! & danger"
ENDLOCAL

This replacement is not safe with %...% style expansion!

^{In case of OP bash -c "g++-linux-4.1 !v_params:"=\"!" is the safe version.}

If for some reason even temporarily enabling DELAYEDEXPANSION is not an option, read on:

Using \" from within cmd is a little bit safer if one always needs to escape special characters, instead of just sometimes. (It's less likely to forget a caret, if it's consistent...)

To achieve this, one precedes any quote with a caret (^"), quotes that should reach the child process as literals must additionally be escaped with a backlash (\^"). ALL shell meta characters must be escaped with ^ as well, e.g. & => ^&; | => ^|; > => ^>; etc.

Example:

child ^"malicious argument\^"^&whoami^"

Source: Everyone quotes command line arguments the wrong way, see "A better method of quoting"

To pass dynamic content, one needs to ensure the following:
The part of the command that contains the variable must be considered "quoted" by cmd.exe (This is impossible if the variable can contain quotes - don't write %var:""=\"%). To achieve this, the last " before the variable and the first " after the variable are not ^-escaped. cmd-metacharacters between those two " must not be escaped. Example:

foo.exe ^"danger ^& bar=\"region with %dynamic_content% & danger\"^"

This isn't safe, if %dynamic_content% can contain unmatched quotes.

Just use this: ExtractFilePath(your_path_file_name)

I am sorry if i am late to reply here but i just thought i should throw in a much simpler solution for the OpenDialog.

OpenDialog ofd = new OpenDialog();
var fullPathIncludingFileName = ofd.Filename; //returns the full path including the filename
var fullPathExcludingFileName = ofd.Filename.Replace(ofd.SafeFileName, "");//will remove the filename from the full path

I have not yet used a FolderBrowserDialog before so i will trust my fellow coders's take on this. I hope this helps.

I was having the same issue by using an IF statement to return an unwanted value to "", and the chart would do as you described.

However, when I used #N/A instead of "" (important, note that it's without the quotation marks as in #N/A and not "#N/A"), the chart ignored the invalid data. I even tried putting in an invalid FALSE statement and it worked the same, the only difference was #NAME? returned as the error in the cell instead of #N/A. I will use a made up IF statement to show you what I mean:

=IF(A1>A2,A3,"")  
---> Returned "" into cell when statement is FALSE and plotted on chart 
     (this is unwanted as you described)

=IF(A1>A2,A3,"#N/A")  
---> Returned #N/A as text when statement is FALSE and plotted on chart 
     (this is also unwanted as you described)

=IF(A1>A2,A3,#N/A)  
---> Returned #N/A as Error when statement is FALSE and does not plot on chart (Ideal)

=IF(A1>A2,A3,a)  
---> Returned #NAME? as Error when statement is FALSE and does not plot on chart 
    (Ideal, and this is because any letter without quotations is not a valid statement)

Definitely avoid using eval to do something like this, or you will open yourself to XSS (Cross-Site Scripting) vulnerabilities.

For example, if you were to use the eval solutions proposed here, a nefarious user could send a link to their victim that looked like this:

http://yoursite.com/foo.html?func=function(){alert('Im%20In%20Teh%20Codez');}

And their javascript, not yours, would get executed. This code could do something far worse than just pop up an alert of course; it could steal cookies, send requests to your application, etc.

So, make sure you never eval untrusted code that comes in from user input (and anything on the query string id considered user input). You could take user input as a key that will point to your function, but make sure that you don't execute anything if the string given doesn't match a key in your object. For example:

// set up the possible functions:
var myFuncs = {
  func1: function () { alert('Function 1'); },
  func2: function () { alert('Function 2'); },
  func3: function () { alert('Function 3'); },
  func4: function () { alert('Function 4'); },
  func5: function () { alert('Function 5'); }
};
// execute the one specified in the 'funcToRun' variable:
myFuncs[funcToRun]();

This will fail if the funcToRun variable doesn't point to anything in the myFuncs object, but it won't execute any code.

My idea is to get max of rows count of all data.frames and next append empty matrix to every data.frame if need. This method doesn't require additional packages, only base is used. Code looks following:

list.df <- list(data.frame(a = 1:10), data.frame(a = 1:5), data.frame(a = 1:3))

max.rows <- max(unlist(lapply(list.df, nrow), use.names = F))

list.df <- lapply(list.df, function(x) {
    na.count <- max.rows - nrow(x)
    if (na.count > 0L) {
        na.dm <- matrix(NA, na.count, ncol(x))
        colnames(na.dm) <- colnames(x)
        rbind(x, na.dm)
    } else {
        x
    }
})

do.call(cbind, list.df)

#     a  a  a
# 1   1  1  1
# 2   2  2  2
# 3   3  3  3
# 4   4  4 NA
# 5   5  5 NA
# 6   6 NA NA
# 7   7 NA NA
# 8   8 NA NA
# 9   9 NA NA
# 10 10 NA NA

The code that you have would work, but is executed from the global context, which means that this refers to the global object.

<script type="text/javascript">
var foo = function(param) {
    param.innerHTML = "Not a button";
};
</script>
<button onclick="foo(this)" id="bar">Button</button>

You can also use the non-inline alternative, which attached to and executed from the specific element context which allows you to access the element from this.

<script type="text/javascript">
document.getElementById('bar').onclick = function() {
    this.innerHTML = "Not a button";
};
</script>
<button id="bar">Button</button>

As per Android Documentation RecyclerView is the new way to organize the items in listview and to be displayed horizontally

Advantages:

1. Since by using Recyclerview Adapter, ViewHolder pattern is automatically implemented
2. Animation is easy to perform
3. Many more features

More Information about RecyclerView:

Just add the below block to make the ListView to horizontal from vertical

Code-snippet

LinearLayoutManager layoutManager= new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL, false);
mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
mRecyclerView.setLayoutManager(layoutManager);

Could you try this one:

create or replace

BEGIN
  FOR thisteam in (select P.FIRSTNAME,P.LASTNAME, SUM(P.PTS) S from PLAYERREGULARSEASON P  where P.TEAM = 'IND'  group by P.FIRSTNAME, P.LASTNAME order by SUM(P.PTS) DESC)
  LOOP
    dbms_output.put_line(thisteam.FIRSTNAME|| ' ' || thisteam.LASTNAME  || ':' || thisteam.S);
  END LOOP;

END;

ok i spent some frustrating time with this problem too. My little guide.

Open desktop for example. If you didnt switch your disc in cmd, type:

cd desktop

Now if you want to display subfolders:

cd, make 1 spacebar, and press tab 2 times

Now if you want to enter directory/file with SPACE IN NAME. Lets open some file name f.g., to open it we need to type:

cd file\ name

p.s. notice this space after slash :)

In IE11 Windows 7 this worked for me,

You should delete a line apply plugin: 'com.google.gms.google-services'

because "com.android.application" package already has same package.

Well, even in Java 8, long and int are still signed, only some methods treat them as if they were unsigned. If you want to write unsigned long literal like that, you can do

static long values = Long.parseUnsignedLong("18446744073709551615");

public static void main(String[] args) {
    System.out.println(values); // -1
    System.out.println(Long.toUnsignedString(values)); // 18446744073709551615
}

Note : This answer is now out-of-date. This changes the theme in "preview" only as @imjohnking and @john-ktejik pointed out. As @Shahzeb mentioned, theme can modified in res>values>styles

Android Studio 0.8.2 provides a slightly easier way to change the theme. In the preview window, you can select the theme of "Holo.Light.DarkActionBar" by clicking on the theme combo box just above the phone.

Or do a ctrl + click on the @style/AppTheme in the Android manifest file. It will open styles.xml file where you can change the parent attribute of the style tag.

• Theme.Holo for a "dark" theme.
• Theme.Holo.Light for a "light" theme.

When using the Support Library, you must instead use the Theme.AppCompat themes:

• Theme.AppCompat for the "dark" theme.
• Theme.AppCompat.Light for the "light" theme.
• Theme.AppCompat.Light.DarkActionBar for the light theme with a dark action bar.

ENV MALLOC_ARENA_MAX=4

There is an IBM article about setting MALLOC_ARENA_MAX https://www.ibm.com/developerworks/community/blogs/kevgrig/entry/linux_glibc_2_10_rhel_6_malloc_may_show_excessive_virtual_memory_usage?lang=en

This blog post says

resident memory has been known to creep in a manner similar to a memory leak or memory fragmentation.

There is also an open JDK bug JDK-8193521 "glibc wastes memory with default configuration"

search for MALLOC_ARENA_MAX on Google or SO for more references.

You might want to tune also other malloc options to optimize for low fragmentation of allocated memory:

# tune glibc memory allocation, optimize for low fragmentation
# limit the number of arenas
export MALLOC_ARENA_MAX=2
# disable dynamic mmap threshold, see M_MMAP_THRESHOLD in "man mallopt"
export MALLOC_MMAP_THRESHOLD_=131072
export MALLOC_TRIM_THRESHOLD_=131072
export MALLOC_TOP_PAD_=131072
export MALLOC_MMAP_MAX_=65536

For primitive values like numbers and strings this is an easy solution:

a = [1,2,3]

b = [3,2,1]

a.sort().toString() == b.sort().toString() 

The call to sort() will ensure that the order of the elements does not matter. The toString() call will create a string with the values comma separated so both strings can be tested for equality.

In my case, the original repository was a bare one.

So, I had to type (in windows):

mkdir   dest
cd dest
git init
git remote add origin a\valid\yet\bare\repository
git pull origin master

To check if a repository is a bare one:

git rev-parse --is-bare-repository 

If you are using jQuery, it is possible to disable rightclick on the whole page like this:

$( document ).ready(function() {
    $("html").on("contextmenu",function(){
        return false;});}

class EnumStringToInt // to search for a string in enum
{
    enum Numbers{one,two,hree};
    static void Main()
    {
        Numbers num = Numbers.one; // converting enum to string
        string str = num.ToString();
        //Console.WriteLine(str);
        string str1 = "four";
        string[] getnames = (string[])Enum.GetNames(typeof(Numbers));
        int[] getnum = (int[])Enum.GetValues(typeof(Numbers));
        try
        {
            for (int i = 0; i <= getnum.Length; i++)
            {
                if (str1.Equals(getnames[i]))
                {
                    Numbers num1 = (Numbers)Enum.Parse(typeof(Numbers), str1);
                    Console.WriteLine("string found:{0}", num1);
                }
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("Value not found!", ex);
        }
    }
}

The python error says that wordInput is not an iterable -> it is of NoneType.

If you print wordInput before the offending line, you will see that wordInput is None.

Since wordInput is None, that means that the argument passed to the function is also None. In this case word. You assign the result of pickEasy to word.

The problem is that your pickEasy function does not return anything. In Python, a method that didn't return anything returns a NoneType.

I think you wanted to return a word, so this will suffice:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

It should be like

params.permit(:id => [])

Also since rails version 4+ you can use:

params.permit(id: [])

try following:

UPDATE `list` SET `test` = `number` 

it creates copy of all values from "number" and paste it to "test"

You do it exactly as you showed with this line:

get.setHeader("Content-Type", "application/x-zip");

So your header is fine and the problem is some other input to the web service. You'll want to debug that on the server side.

The format you use for the date doesn't match to Oracle's default date format.

A default installation of Oracle Database sets the DEFAULT DATE FORMAT to dd-MMM-yyyy.

Either use the function TO_DATE(dateStr, formatStr) or simply use dd-MMM-yyyy date format model.

Short answer: You can't.

Long answer: You could use a modal to display a popup with the image you need.

You can refer to this as an example to a modal.

Josh's comments are spot on. If you are not super familiar with critical values I'd suggest playing with qt, reading the manual (?qt) in conjunction with looking at a look up table (LINK). When I first moved from SPSS to R I created a function that made critical t value look up pretty easy (I'd never use this now as it takes too much time and with the p values that are generally provided in the output it's a moot point). Here's the code for that:

critical.t <- function(){
    cat("\n","\bEnter Alpha Level","\n")
    alpha<-scan(n=1,what = double(0),quiet=T)
    cat("\n","\b1 Tailed or 2 Tailed:\nEnter either 1 or 2","\n")
    tt <- scan(n=1,what = double(0),quiet=T)
    cat("\n","\bEnter Number of Observations","\n")
    n <- scan(n=1,what = double(0),quiet=T)
    cat("\n\nCritical Value =",qt(1-(alpha/tt), n-2), "\n")
}

critical.t()

Or you can use javascript to redirect to another page:

<script type="text/javascript">
    function toRedirect() {
        window.location.href="new.aspx";
    }
</script>

Call this toRedirect() function from client (for ex: onload event of body tag) or from server using:

ClientScript.RegisterStartupScript(this.gettype(),"Redirect","toRedirect()",true);

Should I use(or both) for signing apk for play store release? An answer is YES.

As per https://source.android.com/security/apksigning/v2.html#verification :

In Android 7.0, APKs can be verified according to the APK Signature Scheme v2 (v2 scheme) or JAR signing (v1 scheme). Older platforms ignore v2 signatures and only verify v1 signatures.

I tried to generate build with checking V2(Full Apk Signature) option. Then when I tried to install a release build in below 7.0 device and I am unable to install build in the device.

After that I tried to build by checking both version checkbox and generate release build. Then able to install build.

Threaded stoppable function

Instead of subclassing threading.Thread, one can modify the function to allow stopping by a flag.

We need an object, accessible to running function, to which we set the flag to stop running.

We can use threading.currentThread() object.

import threading
import time


def doit(arg):
    t = threading.currentThread()
    while getattr(t, "do_run", True):
        print ("working on %s" % arg)
        time.sleep(1)
    print("Stopping as you wish.")


def main():
    t = threading.Thread(target=doit, args=("task",))
    t.start()
    time.sleep(5)
    t.do_run = False
    t.join()

if __name__ == "__main__":
    main()

The trick is, that the running thread can have attached additional properties. The solution builds on assumptions:

• the thread has a property "do_run" with default value True
• driving parent process can assign to started thread the property "do_run" to False.

Running the code, we get following output:

$ python stopthread.py                                                        
working on task
working on task
working on task
working on task
working on task
Stopping as you wish.

Pill to kill - using Event

Other alternative is to use threading.Event as function argument. It is by default False, but external process can "set it" (to True) and function can learn about it using wait(timeout) function.

We can wait with zero timeout, but we can also use it as the sleeping timer (used below).

def doit(stop_event, arg):
    while not stop_event.wait(1):
        print ("working on %s" % arg)
    print("Stopping as you wish.")


def main():
    pill2kill = threading.Event()
    t = threading.Thread(target=doit, args=(pill2kill, "task"))
    t.start()
    time.sleep(5)
    pill2kill.set()
    t.join()

Edit: I tried this in Python 3.6. stop_event.wait() blocks the event (and so the while loop) until release. It does not return a boolean value. Using stop_event.is_set() works instead.

Stopping multiple threads with one pill

Advantage of pill to kill is better seen, if we have to stop multiple threads at once, as one pill will work for all.

The doit will not change at all, only the main handles the threads a bit differently.

def main():
    pill2kill = threading.Event()
    tasks = ["task ONE", "task TWO", "task THREE"]

    def thread_gen(pill2kill, tasks):
        for task in tasks:
            t = threading.Thread(target=doit, args=(pill2kill, task))
            yield t

    threads = list(thread_gen(pill2kill, tasks))
    for thread in threads:
        thread.start()
    time.sleep(5)
    pill2kill.set()
    for thread in threads:
        thread.join()

I use git add --patch quite a bit and wanted something like this to avoid having to hit d all the time through the same files. I whipped up a very hacky couple of git aliases to get the job done:

[alias]
    HELPER-CHANGED-FILTERED = "!f() { git status --porcelain | cut -c4- | ( [[ \"$1\" ]] && egrep -v \"$1\" || cat ); }; f"
    ap                      = "!git add --patch -- $(git HELPER-CHANGED-FILTERED 'min.(js|css)$' || echo 'THIS_FILE_PROBABLY_DOESNT_EXIST' )"

In my case I just wanted to ignore certain minified files all the time, but you could make it use an environment variable like $GIT_EXCLUDE_PATTERN for a more general use case.

From the asar documentation

(the use of npx here is to avoid to install the asar tool globally with npm install -g asar)

Extract the whole archive:

npx asar extract app.asar destfolder 

Extract a particular file:

npx asar extract-file app.asar main.js

Events are pretty easy in C#, but the MSDN docs in my opinion make them pretty confusing. Normally, most documentation you see discusses making a class inherit from the EventArgs base class and there's a reason for that. However, it's not the simplest way to make events, and for someone wanting something quick and easy, and in a time crunch, using the Action type is your ticket.

Creating Events & Subscribing To Them

1. Create your event on your class right after your class declaration.

public event Action<string,string,string,string>MyEvent;

2. Create your event handler class method in your class.

private void MyEventHandler(string s1,string s2,string s3,string s4)
{
  Console.WriteLine("{0} {1} {2} {3}",s1,s2,s3,s4);
}

3. Now when your class is invoked, tell it to connect the event to your new event handler. The reason the += operator is used is because you are appending your particular event handler to the event. You can actually do this with multiple separate event handlers, and when an event is raised, each event handler will operate in the sequence in which you added them.

class Example
{
  public Example() // I'm a C# style class constructor
  {
    MyEvent += new Action<string,string,string,string>(MyEventHandler);
  }
}

4. Now, when you're ready, trigger (aka raise) the event somewhere in your class code like so:

MyEvent("wow","this","is","cool");

The end result when you run this is that the console will emit "wow this is cool". And if you changed "cool" with a date or a sequence, and ran this event trigger multiple times, you'd see the result come out in a FIFO sequence like events should normally operate.

In this example, I passed 4 strings. But you could change those to any kind of acceptable type, or used more or less types, or even remove the <...> out and pass nothing to your event handler.

And, again, if you had multiple custom event handlers, and subscribed them all to your event with the += operator, then your event trigger would have called them all in sequence.

Identifying Event Callers

But what if you want to identify the caller to this event in your event handler? This is useful if you want an event handler that reacts with conditions based on who's raised/triggered the event. There are a few ways to do this. Below are examples that are shown in order by how fast they operate:

Option 1. (Fastest) If you already know it, then pass the name as a literal string to the event handler when you trigger it.

Option 2. (Somewhat Fast) Add this into your class and call it from the calling method, and then pass that string to the event handler when you trigger it:

private static string GetCaller([System.Runtime.CompilerServices.CallerMemberName] string s = null) => s;

Option 3. (Least Fast But Still Fast) In your event handler when you trigger it, get the calling method name string with this:

string callingMethod = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod().ReflectedType.Name.Split('<', '>')[1];

Unsubscribing From Events

You may have a scenario where your custom event has multiple event handlers, but you want to remove one special one out of the list of event handlers. To do so, use the -= operator like so:

MyEvent -= MyEventHandler;

A word of minor caution with this, however. If you do this and that event no longer has any event handlers, and you trigger that event again, it will throw an exception. (Exceptions, of course, you can trap with try/catch blocks.)

Clearing All Events

Okay, let's say you're through with events and you don't want to process any more. Just set it to null like so:

MyEvent = null;

The same caution for Unsubscribing events is here, as well. If your custom event handler no longer has any events, and you trigger it again, your program will throw an exception.

I think the classic answer is to create a more decoupled application, which has no knowledge of which implementation will be used during runtime.

For example, we're a central payment provider, working with many payment providers around the world. However, when a request is made, I have no idea which payment processor I'm going to call. I could program one class with a ton of switch cases, such as:

class PaymentProcessor{

    private String type;

    public PaymentProcessor(String type){
        this.type = type;
    }

    public void authorize(){
        if (type.equals(Consts.PAYPAL)){
            // Do this;
        }
        else if(type.equals(Consts.OTHER_PROCESSOR)){
            // Do that;
        }
    }
}

Now imagine that now you'll need to maintain all this code in a single class because it's not decoupled properly, you can imagine that for every new processor you'll support, you'll need to create a new if // switch case for every method, this only gets more complicated, however, by using Dependency Injection (or Inversion of Control - as it's sometimes called, meaning that whoever controls the running of the program is known only at runtime, and not complication), you could achieve something very neat and maintainable.

class PaypalProcessor implements PaymentProcessor{

    public void authorize(){
        // Do PayPal authorization
    }
}

class OtherProcessor implements PaymentProcessor{

    public void authorize(){
        // Do other processor authorization
    }
}

class PaymentFactory{

    public static PaymentProcessor create(String type){

        switch(type){
            case Consts.PAYPAL;
                return new PaypalProcessor();

            case Consts.OTHER_PROCESSOR;
                return new OtherProcessor();
        }
    }
}

interface PaymentProcessor{
    void authorize();
}

** The code won't compile, I know :)

Visual Assist: link.

Install, load solution, press Shift+Alt+O, search for files in solution by substring. Try also Shift+Alt+S, for the equivalent for symbols. This addin has a bunch of completion popup and syntax colouring stuff in it that aren't to all tastes, but the code browsing features are done well and seem uncontroversial.

Judging by comments on the forums, compatibility with Resharper is something they pay attention to.

For free, try also Nifty Solution: link.

I haven't used this myself, but I use the author's Nifty Perforce plugin, and that is pretty tidy.

Since Python 3.5, you can also use splat * unpacking syntax to unpack a generator expresion:

*(x for x in range(10)),

Check this. Also you can change it as per your preference.

Well, all I can see there is that you have two JSON objects, seperated by a comma. If both of them were inside an array ([...]) it would make more sense.

And, if they ARE inside of an array, then you would just be using the standard "for var i = 0..." type of loop. As it is, I think it's going to try to retrieve the "id" property of the string "1", then "id" of "hi", and so on.

Deep Learning

Gather at least a few hundred images containing cola cans, annotate the bounding box around them as positive classes, include cola bottles and other cola products label them negative classes as well as random objects.

Unless you collect a very large dataset, perform the trick of using deep learning features for small dataset. Ideally using a combination of Support Vector Machines(SVM) with deep neural nets.

Once you feed the images to a previously trained deep learning model(e.g. GoogleNet), instead of using neural network's decision (final) layer to do classifications, use previous layer(s)' data as features to train your classifier.

So performatic as the Sam Saffron's approach.

public static IEnumerable<IEnumerable<T>> Batch<T>(this IEnumerable<T> source, int size)
{
    if (source == null) throw new ArgumentNullException(nameof(source));
    if (size <= 0) throw new ArgumentOutOfRangeException(nameof(size), "Size must be greater than zero.");

    return BatchImpl(source, size).TakeWhile(x => x.Any());
}

static IEnumerable<IEnumerable<T>> BatchImpl<T>(this IEnumerable<T> source, int size)
{
    var values = new List<T>();
    var group = 1;
    var disposed = false;
    var e = source.GetEnumerator();

    try
    {
        while (!disposed)
        {
            yield return GetBatch(e, values, group, size, () => { e.Dispose(); disposed = true; });
            group++;
        }
    }
    finally
    {
        if (!disposed)
            e.Dispose();
    }
}

static IEnumerable<T> GetBatch<T>(IEnumerator<T> e, List<T> values, int group, int size, Action dispose)
{
    var min = (group - 1) * size + 1;
    var max = group * size;
    var hasValue = false;

    while (values.Count < min && e.MoveNext())
    {
        values.Add(e.Current);
    }

    for (var i = min; i <= max; i++)
    {
        if (i <= values.Count)
        {
            hasValue = true;
        }
        else if (hasValue = e.MoveNext())
        {
            values.Add(e.Current);
        }
        else
        {
            dispose();
        }

        if (hasValue)
            yield return values[i - 1];
        else
            yield break;
    }

}

For pipeline:

     BRANCH_NAME = "${GIT_BRANCH.split("/")[1]}"
  }

pod setup --verbose 

I am running the above mentioned command right now but as mentioned by @Joe Blow, it shows absolutely no information on the progress.

But if you open the Activity Monitor on Mac (Task Manager on Windows?), under the 'Network' tab you will see a process named 'git-remote-https' and it shows the size of 'Received Bytes' increasing. After downloading about 300MB it stopped and then I could see further progress in the Terminal window.

Consider using more_itertools.unzip:

>>> from more_itertools import unzip
>>> original = [('a', 1), ('b', 2), ('c', 3), ('d', 4)]
>>> [list(x) for x in unzip(original)]
[['a', 'b', 'c', 'd'], [1, 2, 3, 4]]     

If you can add another wrapping div "block3" you could do something like this.

 <html>
      <head>
      <style type="text/css">
      .block1 {color:red;width:120px;border:1px solid green; height: 100px;}
      .block3 {float:left; width:10px;}
      .block2 {color:blue;width:70px;border:2px solid black;position:relative;float:right;}
      </style>
      </head>

    <body>
    <div class='block1'>

        <div class='block3'>
            <p>text1</p>
            <p>text2</p>
        </div>

        <div class='block2'>block2</DIV>

    </div>

    </body>
    </html>

A couple of wires are crossed here. The various autoplay settings that you're working with only affect whether the SWF's root timeline starts out paused or not. So if your SWF had a timeline animation, or if it had an embedded video on the root timeline, then these settings would do what you're after.

However, the SWF you're working with almost certainly has only one frame on its timeline, so these settings won't affect playback at all. That one frame contains some flavor of video playback component, which contains ActionScript that controls how the video behaves. To get that player component to start of paused, you'll have to change the settings of the component itself.

Without knowing more about where the content came from it's hard to say more, but when one publishes from Flash, video player components normally include a parameter for whether to autoplay. If your SWF is being published by an application other than Flash (Captivate, I suppose, but I'm not up on that) then your best bet would be to check the settings for that app. Anyway it's not something you can control from the level of the HTML page. (Unless you were talking to the SWF from JavaScript, and for that to work the video component would have to be designed to allow it.)

As Nikita Skvortsov pointed out, a self-closing div will not validate. This is because a div is a normal element, not a void element.

According to the HTML5 spec, tags that cannot have any contents (known as void elements) can be self-closing*. This includes the following tags:

area, base, br, col, embed, hr, img, input, 
keygen, link, meta, param, source, track, wbr

The "/" is completely optional on the above tags, however, so <img/> is not different from <img>, but <img></img> is invalid.

*Note: foreign elements can also be self-closing, but I don't think that's in scope for this answer.

Just came across this one, as I need to print all models with their attributes(built on @Aditya Sanghi's comment):

ActiveRecord::Base.connection.tables.map{|x|x.classify.safe_constantize}.compact.each{ |model| print "\n\n"+model.name; model.new.attributes.each{|a,b| print "\n#{a}"}}

Update 2018

While everything written below still holds true, Rails 5.2 now includes active_storage, which allows stuff like uploading directly to S3 (or other cloud storage services), image transformations, etc. You should check out the rails guide and decide for yourself what fits your needs.

While there are plenty of gems that solve file uploading pretty nicely (see https://www.ruby-toolbox.com/categories/rails_file_uploads for a list), rails has built-in helpers which make it easy to roll your own solution.

Use the file_field-form helper in your form, and rails handles the uploading for you:

<%= form_for @person do |f| %>
  <%= f.file_field :picture %>
<% end %>

You will have access in the controller to the uploaded file as follows:

uploaded_io = params[:person][:picture]
File.open(Rails.root.join('public', 'uploads', uploaded_io.original_filename), 'wb') do |file|
  file.write(uploaded_io.read)
end

It depends on the complexity of what you want to achieve, but this is totally sufficient for easy file uploading/downloading tasks. This example is taken from the rails guides, you can go there for further information: http://guides.rubyonrails.org/form_helpers.html#uploading-files

I tried external project, with multiple apk.

The command from Studio, looked like

adb install-multiple -r ....

Solution -

• select console
• aste command with -t

Try this

//ITEM/*[starts-with(text(),'2552')]/following-sibling::*

• A leading slash tells the browser to start at the root directory.
• If you don't have the leading slash, you're referencing from the current directory.
• If you add two dots before the leading slash, it means you're referencing the parent of the current directory.

Take the following folder structure

notice:

• the ROOT checkmark is green,
• the second checkmark is orange,
• the third checkmark is purple,
• the forth checkmark is yellow

Now in the index.html.en file you'll want to put the following markup

<p>
    <span>src="check_mark.png"</span>
    <img src="check_mark.png" />
    <span>I'm purple because I'm referenced from this current directory</span>
</p>

<p>
    <span>src="/check_mark.png"</span>
    <img src="/check_mark.png" />
    <span>I'm green because I'm referenced from the ROOT directory</span>
</p>

<p>
    <span>src="subfolder/check_mark.png"</span>
    <img src="subfolder/check_mark.png" />
    <span>I'm yellow because I'm referenced from the child of this current directory</span>
</p>

<p>
    <span>src="/subfolder/check_mark.png"</span>
    <img src="/subfolder/check_mark.png" />
    <span>I'm orange because I'm referenced from the child of the ROOT directory</span>
</p>

<p>
    <span>src="../subfolder/check_mark.png"</span>
    <img src="../subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced from the parent of this current directory</span>
</p>

<p>
    <span>src="subfolder/subfolder/check_mark.png"</span>
    <img src="subfolder/subfolder/check_mark.png" />
    <span>I'm [broken] because there is no subfolder two children down from this current directory</span>
</p>

<p>
    <span>src="/subfolder/subfolder/check_mark.png"</span>
    <img src="/subfolder/subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced two children down from the ROOT directory</span>
</p>

Now if you load up the index.html.en file located in the second subfolder
http://example.com/subfolder/subfolder/

This will be your output

you also can use "eval", and pass the method as a string argument, and then simply eval it in the other method.

When you use Angular, try not to use the jquery library. Try using the features and the libraries that are produced for angular framework. If you want to use the jquery functions like find(), html(), closest() and etc.., I suggest using the pure js. example: querySelector(), innerHTML, parentElement and etc...

You are just missing the words "primary key" as far as I can see to meet your specified objective.

For your other columns it's best to explicitly define whether they should be NULL or NOT NULL though so you are not relying on the ANSI_NULL_DFLT_ON setting.

CREATE TABLE #tmp
(
ID INT IDENTITY(1, 1) primary key ,
AssignedTo NVARCHAR(100),
AltBusinessSeverity NVARCHAR(100),
DefectCount int
);

insert into #tmp 
select 'user','high',5 union all
select 'user','med',4


select * from #tmp

This works well and an angular way to focus input control

angular.element('#elementId').focus()

This is although not a pure angular way of doing the task yet the syntax follows angular style. Jquery plays role indirectly and directly access DOM using Angular (jQLite => JQuery Light).

If required, this code can easily be put inside a simple angular directive where element is directly accessible.

if you want to add more attributes just do like:

$('<input>').attr('type','hidden').attr('name','foo[]').attr('value','bar').appendTo('form');

Or

$('<input>').attr({
    type: 'hidden',
    id: 'foo',
    name: 'foo[]',
    value: 'bar'
}).appendTo('form');

Apple documentation says

A subclass version of the copyWithZone: method should send the message to super first, to incorporate its implementation, unless the subclass descends directly from NSObject.

to add to the existing answer

@interface YourClass : NSObject <NSCopying> 
{
   SomeOtherObject *obj;
}

// In the implementation
-(id)copyWithZone:(NSZone *)zone
{
  YourClass *another = [super copyWithZone:zone];
  another.obj = [obj copyWithZone: zone];

  return another;
}

If you didn't push the update in remote then the simple solution is remove last local commit using following command: git reset HEAD^. Then add all files and commit again.

This is the progress bar I have used.

<ProgressBar
     android:padding="@dimen/dimen_5"
     android:layout_below="@+id/txt_chklist_progress"
     android:id="@+id/pb_media_progress"
     style="@style/MyProgressBar"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:layout_gravity="center"
     android:progress="70"
     android:scaleY="5"
     android:max="100"
     android:progressBackgroundTint="@color/white"
     android:progressTint="@color/green_above_avg" />

And this is my style tag

 <style name="MyProgressBar" parent="@style/Widget.AppCompat.ProgressBar.Horizontal">
    <item name="android:progressBackgroundTint">@color/white</item>
    <item name="android:progressTint">@color/green_above_avg</item>
</style>

Everything seems to be perfect in your code except the fact that handleClick() isn't working because this function lacks a parameter in its function call invocation(but the function definition within has an argument which makes a function mismatch to occur).

The following is a sample working code for calculating all semester's total marks and corresponding grade. It demonstrates the use of a JavaScript function(call) within a html file and also solves the problem you are facing.

<!DOCTYPE html>
<html>
<head>
    <title> Semester Results </title>
</head>
<body>
    <h1> Semester Marks </h1> <br> 
    <script type = "text/javascript">
        function checkMarks(total)
        {
            document.write("<h1> Final Result !!! </h1><br>");
            document.write("Total Marks = " + total + "<br><br>");
            var avg = total / 6.0;
            document.write("CGPA = " + (avg / 10.0).toFixed(2) + "<br><br>");
            if(avg >= 90)
                document.write("Grade = A");
            else if(avg >= 80)
                document.write("Grade = B");
            else if(avg >= 70)
                document.write("Grade = C");
            else if(avg >= 60)
                document.write("Grade = D");
            else if(avg >= 50)
                document.write("Grade = Pass");
            else
                document.write("Grade = Fail");
       }
    </script>
    <form name = "myform" action = "javascript:checkMarks(Number(s1.value) + Number(s2.value) + Number(s3.value) + Number(s4.value) + Number(s5.value) + Number(s6.value))"/>
        Semester 1:  <input type = "text" id = "s1"/> <br><br>
        Semester 2:  <input type = "text" id = "s2"/> <br><br>

Ok so i found out the problem :)

ctrl+alt+delete to start task manager, once you get to task manager go to services. find MySQL and right click on it. Then click stop process. That worked for me and i hope it works for you :D

Simple Override onBackPressed Method:

    @Override
    public void onBackPressed() {
            super.onBackPressed();
            this.finish();
    }

This can be done entirely with bash string manipulation:

first="I love Suzy and Mary"
second="Sara"
first=${first/Suzy/$second}

That will replace only the first occurrence; to replace them all, double the first slash:

first="Suzy, Suzy, Suzy"
second="Sara"
first=${first//Suzy/$second}
# first is now "Sara, Sara, Sara"

Since version 3.3 of ggplot2, we have access to the convenient after_stat() function.

We can do something similar to @Andrew's answer, but without using the .. syntax:

# original example data
mydata <- c("aa", "bb", NULL, "bb", "cc", "aa", "aa", "aa", "ee", NULL, "cc")

# display percentages
library(ggplot2)
ggplot(mapping = aes(x = mydata,
                     y = after_stat(count/sum(count)))) +
  geom_bar() +
  scale_y_continuous(labels = scales::percent)

You can find all the "computed variables" available to use in the documentation of the geom_ and stat_ functions. For example, for geom_bar(), you can access the count and prop variables. (See the documentation for computed variables.)

One comment about your NULL values: they are ignored when you create the vector (i.e. you end up with a vector of length 9, not 11). If you really want to keep track of missing data, you will have to use NA instead (ggplot2 will put NAs at the right end of the plot):

# use NA instead of NULL
mydata <- c("aa", "bb", NA, "bb", "cc", "aa", "aa", "aa", "ee", NA, "cc")
length(mydata)
#> [1] 11

# display percentages
library(ggplot2)
ggplot(mapping = aes(x = mydata,
                     y = after_stat(count/sum(count)))) +
  geom_bar() +
  scale_y_continuous(labels = scales::percent)

(Note that using chr or fct data will not make a difference for your example.)

I think, this could be done without IIS URL Rewrite module. <httpRedirect> supports wildcards, so you can configure it this way:

  <system.webServer>
    <httpRedirect enabled="true">
      <add wildcard="/" destination="/menu_1/MainScreen.aspx" />
    </httpRedirect>
  </system.webServer>

Note that you need to have the "HTTP Redirection" feature enabled on IIS - see HTTP Redirects

So, far I have been exiting and reentering the Interpreter because re importing the file again is not working for me.

Yes, just saying import again gives you the existing copy of the module from sys.modules.

You can say reload(module) to update sys.modules and get a new copy of that single module, but if any other modules have a reference to the original module or any object from the original module, they will keep their old references and Very Confusing Things will happen.

So if you've got a module a, which depends on module b, and b changes, you have to ‘reload b’ followed by ‘reload a’. If you've got two modules which depend on each other, which is extremely common when those modules are part of the same package, you can't reload them both: if you reload p.a it'll get a reference to the old p.b, and vice versa. The only way to do it is to unload them both at once by deleting their items from sys.modules, before importing them again. This is icky and has some practical pitfalls to do with modules entries being None as a failed-relative-import marker.

And if you've got a module which passes references to its objects to system modules — for example it registers a codec, or adds a warnings handler — you're stuck; you can't reload the system module without confusing the rest of the Python environment.

In summary: for all but the simplest case of one self-contained module being loaded by one standalone script, reload() is very tricky to get right; if, as you imply, you are using a ‘package’, you will probably be better off continuing to cycle the interpreter.

If I understand you correctly, you're talking about doing a

svn merge -rn:n-1

to back out of an earlier commit, in which case, you're probably looking for

git revert

Try

<select id="xxx" name="xxx" class="input-medium" disabled>

As Abel said, ES Modules in Node >= 14 no longer have require by default.

If you want to add it, put this code at the top of your file:

import { createRequire } from 'module';
const require = createRequire(import.meta.url);

Source: https://nodejs.org/api/modules.html#modules_module_createrequire_filename

Another way, using SESSION

Assign current URL to session (use it on every page)

$_SESSION['rdrurl'] = $_SERVER['REQUEST_URI'];

and in your login page, use

if(isset($_SESSION['rdrurl']))
header('location: '.$_SESSION['rdrurl']);
else
header('location: http://example.com');

Yes, It is possible, Just add a class like anyclass and give some CSS style. Live

To search the whole computer:

gdr -PSProvider 'FileSystem' | %{ ls -r $_.root} 2>$null | where { $_.name -eq "httpd.exe" }

Building on @Waterscroll's response, if you want to use async and await in node 8+:

const fs = require('fs');
const util = require('util');
const readdir = util.promisify(fs.readdir);
const unlink = util.promisify(fs.unlink);
const directory = 'test';

async function toRun() {
  try {
    const files = await readdir(directory);
    const unlinkPromises = files.map(filename => unlink(`${directory}/${filename}`));
    return Promise.all(unlinkPromises);
  } catch(err) {
    console.log(err);
  }
}

toRun();

Use a web debugging proxy with throttling features, like Charles or Fiddler.

You'll find them useful web development in general. The major difference is that Charles is shareware, whereas Fiddler is free.

the best thing to do is :

def wordListToFreqDict(wordlist):
    wordfreq = [wordlist.count(p) for p in wordlist]
    return dict(zip(wordlist, wordfreq))

then try to : wordListToFreqDict(originallist)

If it's working from Postman, try new Spring version, becouse the 'org.springframework.boot' 2.2.2.RELEASE version can throw "Required request body content is missing" exception.
Try 2.2.6.RELEASE version.

I think buffers are e.g. useful when interfacing python to native libraries. (Guido van Rossum explains buffer in this mailinglist post).

For example, numpy seems to use buffer for efficient data storage:

import numpy
a = numpy.ndarray(1000000)

the a.data is a:

<read-write buffer for 0x1d7b410, size 8000000, offset 0 at 0x1e353b0>

Edit: Thanks Marc, read up on the struct vs class issue and you're right, thank you!

I tend to use the following method for doing what you describe, using a static method of JSon.Net:

MyObject deserializedObject = JsonConvert.DeserializeObject<MyObject>(json);

Link: Serializing and Deserializing JSON with Json.NET

For the Objects list, may I suggest using generic lists out made out of your own small class containing attributes and position class. You can use the Point struct in System.Drawing (System.Drawing.Point or System.Drawing.PointF for floating point numbers) for you X and Y.

After object creation it's much easier to get the data you're after vs. the text parsing you're otherwise looking at.

string result = Encoding.UTF8.GetString((stream as MemoryStream).ToArray());

In addition to Jesse Glick answer, if you want to pass string parameter then use:

build job: 'your-job-name', 
    parameters: [
        string(name: 'passed_build_number_param', value: String.valueOf(BUILD_NUMBER)),
        string(name: 'complex_param', value: 'prefix-' + String.valueOf(BUILD_NUMBER))
    ]

You can combine "scroll" and "scrollstop" events in order to achieve desired result:

$(window).on("scroll",function(){
   $('nav').addClass('shrink');
}); 
$(window).on("scrollstop",function(){
   $('nav').removeClass('shrink');
}); 

The reason I think is that ProgressDialog is attached to the activity that props up the ProgressDialog as the dialog cannot remain after the activity gets destroyed so it needs to be passed this(ActivityContext) that also gets destroyed with the activity whereas the ApplicationContext remains even after the activity gets destroyed.

Here is a quick console app to depict the concept of how to solve your issue.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication3
{
    public class myobj
    {
        private string a = string.Empty;
        private string b = string.Empty;

        public myobj(string a, string b)
        {
            this.a = a;
            this.b = b;
        }

        public string A
        {
            get
            {
                return a;
            }
        }

        public string B
        {
            get
            {
                return b;
            }
        }
    }


    class Program
    {
        static void Main(string[] args)
        {
            List<myobj> list = new List<myobj>();
            myobj[] objects = { new myobj("a", "b"), new myobj("c", "d"), new myobj("a", "b") };


            for (int i = 0; i < objects.Length; i++)
            {
                if (!list.Exists((delegate(myobj x) { return (string.Equals(x.A, objects[i].A) && string.Equals(x.B, objects[i].B)) ? true : false; })))
                {
                    list.Add(objects[i]);
                }
            }
        }
    }
}

Enjoy!

Remove the * from your query and use individual column names, like this:

SELECT SOME_OTHER_COLUMN, CONCAT(FIRSTNAME, ',', LASTNAME) AS FIRSTNAME FROM `customer`;

Using * means, in your results you want all the columns of the table. In your case * will also include FIRSTNAME. You are then concatenating some columns and using alias of FIRSTNAME. This creates 2 columns with same name.

Url addresses must be preceded by http://

After exiting eclipse I moved .eclipse (found in the user's home directory) to .eclipse.old (just in case I may have had to undo). The error does not show up any more and my projects are working fine after restarting eclipse.

Caution: I have a simple setup and this may not be the best for environments with advanced settings.

I am posting this as a separate answer as previously listed methods did not work for me.

I recently published a jQuery plugin which allows you to make PHP function calls in various ways: https://github.com/Xaxis/jquery.php

Simple example usage:

// Both .end() and .data() return data to variables
var strLenA = P.strlen('some string').end();
var strLenB = P.strlen('another string').end();
var totalStrLen = strLenA + strLenB;
console.log( totalStrLen ); // 25

// .data Returns data in an array
var data1 = P.crypt("Some Crypt String").data();
console.log( data1 ); // ["$1$Tk1b01rk$shTKSqDslatUSRV3WdlnI/"]

I have solved as plist file.

1. Add a NSAppTransportSecurity : Dictionary.
2. Add Subkey named " NSAllowsArbitraryLoads " as Boolean : YES

Try adding position relative, remove width and float properties of the right side, then add left and right property with 0 value.

Also, you can add margin left rule with the value is based on the left element's width (+ some pixels if you need space in between) to maintain its position.

This example is working for me:

   #search {
        width: 160px;
        height: 25px;
        float: left;
        background-color: #FFF;
    }

    #navigation {  
        display: block;  
        position: relative;
        left: 0;
        right: 0;
        margin: 0 0 0 166px;             
        background-color: #A53030;
    }

visualswing4eclipse looks good but the eclipse update URL didn't work for me (I raised ticket 137)

I was only able to install a previous version. Here's a url in case anyone wants it: http://visualswing4eclipse.googlecode.com/svn-history/r858/trunk/org.dyno.visual.swing.site/site.xml

The plugin actually looks very good.

In case you want to initialize a fixed array of pre-initialized equal (non-null or other than default) elements, use this:

var array = Enumerable.Repeat(string.Empty, 37).ToArray();

Also please take part in this discussion.

To do it in pure javascript without jquery or predefining everything you can cycle the encoded html string through an elements innerHTML and innerText(/textContent) properties for every decode step that is required:

<html>
  <head>
    <title>For every decode step, cycle through innerHTML and innerText </title>
    <script>
function decode(str) {
  var d = document.createElement("div");
  d.innerHTML = str; 
  return typeof d.innerText !== 'undefined' ? d.innerText : d.textContent;
}
    </script>
  </head>
  <body>
    <script>
var encodedString = "&lt;p&gt;name&lt;/p&gt;&lt;p&gt;&lt;span style=\"font-size:xx-small;\"&gt;ajde&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;em&gt;da&lt;/em&gt;&lt;/p&gt;";
    </script>
    <input type=button onclick="document.body.innerHTML=decode(encodedString)"/>
  </body>
</html>

You can use URL Encoding Functions PHP has the

rawurlencode() 

function

ASP has the

Server.URLEncode() 

function

In JavaScript you can use the

encodeURIComponent() 

function.

You can try Thread.currentThread().isDaemon()

Try changing the AppPool Manged Pipeline Mode from "Integration" to "Classic".

From matplotlib version 2.1 onwards, you may use a figure legend. Instead of ax.legend(), which produces a legend with the handles from the axes ax, one can create a figure legend

fig.legend(loc="upper right")

which will gather all handles from all subplots in the figure. Since it is a figure legend, it will be placed at the corner of the figure, and the loc argument is relative to the figure.

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0,10)
y = np.linspace(0,10)
z = np.sin(x/3)**2*98

fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(x,y, '-', label = 'Quantity 1')

ax2 = ax.twinx()
ax2.plot(x,z, '-r', label = 'Quantity 2')
fig.legend(loc="upper right")

ax.set_xlabel("x [units]")
ax.set_ylabel(r"Quantity 1")
ax2.set_ylabel(r"Quantity 2")

plt.show()

In order to place the legend back into the axes, one would supply a bbox_to_anchor and a bbox_transform. The latter would be the axes transform of the axes the legend should reside in. The former may be the coordinates of the edge defined by loc given in axes coordinates.

fig.legend(loc="upper right", bbox_to_anchor=(1,1), bbox_transform=ax.transAxes)

You can use Object.keys(), "which returns an array of a given object's own enumerable property names, in the same order as we get with a normal loop."

You can use any object in place of stats:

var stats = {_x000D_
  a: 3,_x000D_
  b: 6,_x000D_
  d: 7,_x000D_
  erijgolekngo: 35_x000D_
}_x000D_
/*  this is the answer here  */_x000D_
for (var key in Object.keys(stats)) {_x000D_
  var t = Object.keys(stats)[key];_x000D_
  console.log(t + " value =: " + stats[t]);_x000D_
}

Having been bitten by this, I have a habit of including locally defined variables in the innermost scope which I use to transfer to any closure. In your example:

foreach (var s in strings)
    query = query.Where(i => i.Prop == s); // access to modified closure

I do:

foreach (var s in strings)
{
    string search = s;
    query = query.Where(i => i.Prop == search); // New definition ensures unique per iteration.
}        

Once you have that habit, you can avoid it in the very rare case you actually intended to bind to the outer scopes. To be honest, I don't think I have ever done so.

To answer this question, we have to look at how indexing a multidimensional array works in Numpy. Let's first say you have the array x from your question. The buffer assigned to x will contain 16 ascending integers from 0 to 15. If you access one element, say x[i,j], NumPy has to figure out the memory location of this element relative to the beginning of the buffer. This is done by calculating in effect i*x.shape[1]+j (and multiplying with the size of an int to get an actual memory offset).

If you extract a subarray by basic slicing like y = x[0:2,0:2], the resulting object will share the underlying buffer with x. But what happens if you acces y[i,j]? NumPy can't use i*y.shape[1]+j to calculate the offset into the array, because the data belonging to y is not consecutive in memory.

NumPy solves this problem by introducing strides. When calculating the memory offset for accessing x[i,j], what is actually calculated is i*x.strides[0]+j*x.strides[1] (and this already includes the factor for the size of an int):

x.strides
(16, 4)

When y is extracted like above, NumPy does not create a new buffer, but it does create a new array object referencing the same buffer (otherwise y would just be equal to x.) The new array object will have a different shape then x and maybe a different starting offset into the buffer, but will share the strides with x (in this case at least):

y.shape
(2,2)
y.strides
(16, 4)

This way, computing the memory offset for y[i,j] will yield the correct result.

But what should NumPy do for something like z=x[[1,3]]? The strides mechanism won't allow correct indexing if the original buffer is used for z. NumPy theoretically could add some more sophisticated mechanism than the strides, but this would make element access relatively expensive, somehow defying the whole idea of an array. In addition, a view wouldn't be a really lightweight object anymore.

This is covered in depth in the NumPy documentation on indexing.

Oh, and nearly forgot about your actual question: Here is how to make the indexing with multiple lists work as expected:

x[[[1],[3]],[1,3]]

This is because the index arrays are broadcasted to a common shape. Of course, for this particular example, you can also make do with basic slicing:

x[1::2, 1::2]

i work on a multi platform project, so i can't use _s function and i don't want pollute my code with visual studio specific code.
my solution is disable the warning 4996 on the visual studio project. go to Project -> Properties -> Configuration properties -> C/C++ -> Advanced -> Disable specific warning add the value 4996.
if you use also the mfc and/or atl library (not my case) define before include mfc _AFX_SECURE_NO_DEPRECATE and before include atl _ATL_SECURE_NO_DEPRECATE.
i use this solution across visual studio 2003 and 2005.

p.s. if you use only visual studio the secure template overloads could be a good solution.

Here's a variant on mkh's answer that runs much faster than it, and scipy.stats.pearsonr, using numba.

import numba

@numba.jit
def corr(data1, data2):
    M = data1.size

    sum1 = 0.
    sum2 = 0.
    for i in range(M):
        sum1 += data1[i]
        sum2 += data2[i]
    mean1 = sum1 / M
    mean2 = sum2 / M

    var_sum1 = 0.
    var_sum2 = 0.
    cross_sum = 0.
    for i in range(M):
        var_sum1 += (data1[i] - mean1) ** 2
        var_sum2 += (data2[i] - mean2) ** 2
        cross_sum += (data1[i] * data2[i])

    std1 = (var_sum1 / M) ** .5
    std2 = (var_sum2 / M) ** .5
    cross_mean = cross_sum / M

    return (cross_mean - mean1 * mean2) / (std1 * std2)

The last update was a while ago, so here is what worked for me on Ubuntu:

sudo apt-get update
sudo apt-get install nginx-extras

Then add the following two lines to the http section of nginx.conf, which is usually located at /etc/nginx/nginx.conf:

sudo nano /etc/nginx/nginx.conf
server_tokens off; # removed pound sign
more_set_headers 'Server: Eff_You_Script_Kiddies!';

Also, don't forget to restart nginx with sudo service nginx restart.

In your particular case: if ($var).

You need to use isset if you don't know whether the variable exists or not. Since you declared it on the very first line though, you know it exists, hence you don't need to, nay, should not use isset.

The same goes for empty, only that empty also combines a check for the truthiness of the value. empty is equivalent to !isset($var) || !$var and !empty is equivalent to isset($var) && $var, or isset($var) && $var == true.

If you only want to test a variable that should exist for truthiness, if ($var) is perfectly adequate and to the point.

I think you may be getting tripped up on the sheet protection. I streamlined your code a little and am explicitly setting references to the workbook and worksheet objects. In your example, you explicitly refer to the workbook and sheet when you're setting the TxtRng object, but not when you unprotect the sheet.

Try this:

Sub varchanger()

    Dim wb As Workbook
    Dim ws As Worksheet
    Dim TxtRng  As Range

    Set wb = ActiveWorkbook
    Set ws = wb.Sheets("Sheet1")
    'or ws.Unprotect Password:="yourpass"
    ws.Unprotect

    Set TxtRng = ws.Range("A1")
    TxtRng.Value = "SubTotal"
    'http://stackoverflow.com/questions/8253776/worksheet-protection-set-using-ws-protect-but-doesnt-unprotect-using-the-menu
    ' or ws.Protect Password:="yourpass"
    ws.Protect

End Sub

If I run the sub with ws.Unprotect commented out, I get a run-time error 1004. (Assuming I've protected the sheet and have the range locked.) Uncommenting the line allows the code to run fine.

NOTES:

1. I'm re-setting sheet protection after writing to the range. I'm assuming you want to do this if you had the sheet protected in the first place. If you are re-setting protection later after further processing, you'll need to remove that line.
2. I removed the error handler. The Excel error message gives you a lot more detail than Err.number. You can put it back in once you get your code working and display whatever you want. Obviously you can use Err.Description as well.
3. The Cells(1, 1) notation can cause a huge amount of grief. Be careful using it. Range("A1") is a lot easier for humans to parse and tends to prevent forehead-slapping mistakes.

font-weight: bold

what I'd call a hack, but given that you're only processing hour values, you can do

 hour=08
 echo $(( ${hour#0} +1 ))
 9
 hour=10 
 echo $(( ${hour#0} +1))
 11

with little risk.

IHTH.

Even though the <head> and <body> tags aren't required, the elements are still there - it's just that the browser can work out where the tags would have been from the rest of the document.

The other elements you're using still have to be inside the <body>

It fires. Check demo http://jsfiddle.net/yeyene/kbAk3/

$("#inline_content input[name='type']").click(function(){
    alert('You clicked radio!');
    if($('input:radio[name=type]:checked').val() == "walk_in"){
        alert($('input:radio[name=type]:checked').val());
        //$('#select-table > .roomNumber').attr('enabled',false);
    }
});

Try this:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
 if (keyCode == KeyEvent.KEYCODE_BACK) {

   return true;
 }
   return super.onKeyDown(keyCode, event);    
}

This query will get you all the tables in the database

USE [DatabaseName];

SELECT * FROM information_schema.tables;

You can use :

sheet.addMergedRegion(new CellRangeAddress(startRowIndx, endRowIndx, startColIndx,endColIndx));

Make sure the CellRangeAddress does not coincide with other merged regions as that will throw an exception.

• If you want to merge cells one above another, keep column indexes same
• If you want to merge cells which are in a single row, keep the row indexes same
• Indexes are zero based

For what you were trying to do this should work:

sheet.addMergedRegion(new CellRangeAddress(rowNo, rowNo, 0, 3));

you can try this

import docx

def getText(filename):
    doc = docx.Document(filename)
    fullText = []
    for para in doc.paragraphs:
        fullText.append(para.text)
    return '\n'.join(fullText)

I ran into this scenario when trying to load a type (via reflection) in an assembly that was built against a different version of a reference common to the application where this error popped up.

As I'm sure the type is unchanged in both versions of the assembly I ended up creating a custom assembly resolver that maps the missing assembly to the one my application has already loaded. Simplest way is to add a static constructor to the program class like so:

using System.Reflection
static Program()
{
    AppDomain.CurrentDomain.AssemblyResolve += (sender, e) => {
        AssemblyName requestedName = new AssemblyName(e.Name);

        if (requestedName.Name == "<AssemblyName>")
        {
            // Load assembly from startup path
            return Assembly.LoadFile($"{Application.StartupPath}\\<AssemblyName>.dll");
        }
        else
        {
            return null;
        }
    };
}

This of course assumes that the Assembly is located in the startup path of the application and can easily be adapted.

Update:

• If you use JavaScript according to ECMAScript 2020 or later, see optional chaining.
• TypeScript has added support for optional chaining in version 3.7.

// use it like this
obj?.a?.lot?.of?.properties

Solution for JavaScript before ECMASCript 2020 or TypeScript older than version 3.7:

A quick workaround is using a try/catch helper function with ES6 arrow function:

function getSafe(fn, defaultVal) {
  try {
    return fn();
  } catch (e) {
    return defaultVal;
  }
}

// use it like this
console.log(getSafe(() => obj.a.lot.of.properties));

// or add an optional default value
console.log(getSafe(() => obj.a.lot.of.properties, 'nothing'));

This will probably have some performance costs when creating the connection but as connections are pooled, they are created only once and then reused, so it won't make any difference to your application. But as always: measure it.

UPDATE:

There are two authentication modes:

1. Windows Authentication mode (corresponding to a trusted connection). Clients need to be members of a domain.
2. SQL Server Authentication mode. Clients are sending username/password at each connection

In many cases, I believe @allcaps's answer works well.

However, sometimes it is necessary to actually rename an app, e.g. to improve code readability or prevent confusion.

Most of the other answers involve either manual database manipulation or tinkering with existing migrations, which I do not like very much.

As an alternative, I like to create a new app with the desired name, copy everything over, make sure it works, then remove the original app:

1. Start a new app with the desired name, and copy all code from the original app into that. Make sure you fix the namespaced stuff, in the newly copied code, to match the new app name.

2. makemigrations and migrate

3. Create a data migration that copies the relevant data from the original app's tables into the new app's tables, and migrate again.

At this point, everything still works, because the original app and its data are still in place.

4. Now you can refactor all the dependent code, so it only makes use of the new app. See other answers for examples of what to look out for.

5. Once you are certain that everything works, you can remove the original app.

This has the advantage that every step uses the normal Django migration mechanism, without manual database manipulation, and we can track everything in source control. In addition, we keep the original app and its data in place until we are sure everything works.

In my case it was a button, and apparently, with buttons, this is only a problem in Firefox. Solution found here:

button::-moz-focus-inner {
  border: 0;
}

To get the column names from pandas dataframe in python3- Here I am creating a data frame from a fileName.csv file

>>> import pandas as pd
>>> df = pd.read_csv('fileName.csv')
>>> columnNames = list(df.head(0)) 
>>> print(columnNames)

For me the problem was wsgi python version mismatch. I was using python 3, so:

$ sudo apt-get remove libapache2-mod-python libapache2-mod-wsgi
$ sudo apt-get install libapache2-mod-wsgi-py3

Warning from @alxs before you copy/paste these commands:
If there are python 2 projects running on the server that use wsgi and apache, the above commands will effectively shut them down.

To get the occurrences of the object from the list directly:

int noOfOccurs = Collections.frequency(animals, "bat");

To get the occurrence of the Object collection inside list, override the equals method in the Object class as:

@Override
public boolean equals(Object o){
    Animals e;
    if(!(o instanceof Animals)){
        return false;
    }else{
        e=(Animals)o;
        if(this.type==e.type()){
            return true;
        }
    }
    return false;
}

Animals(int type){
    this.type = type;
}

Call the Collections.frequency as:

int noOfOccurs = Collections.frequency(animals, new Animals(1));

If you want to add magic comments on all the source files of a project easily, you can use the magic_encoding gem

sudo gem install magic_encoding

then just call magic_encoding in the terminal from the root of your app.

Suppose you have a structure. Inside of that structure are * some sort of name * two variables of the same type but with different meaning

struct foo {
    std::string a;
    std::string b;
};

Okay, now let's say you have a bunch of foos in a container:

// key: some sort of name, value: a foo instance
std::map<std::string, foo> container;

Okay, now suppose you load the data from separate sources, but the data is presented in the same fashion (eg, you need the same parsing method).

You could do something like this:

void readDataFromText(std::istream & input, std::map<std::string, foo> & container, std::string foo::*storage) {
    std::string line, name, value;

    // while lines are successfully retrieved
    while (std::getline(input, line)) {
        std::stringstream linestr(line);
        if ( line.empty() ) {
            continue;
        }

        // retrieve name and value
        linestr >> name >> value;

        // store value into correct storage, whichever one is correct
        container[name].*storage = value;
    }
}

std::map<std::string, foo> readValues() {
    std::map<std::string, foo> foos;

    std::ifstream a("input-a");
    readDataFromText(a, foos, &foo::a);
    std::ifstream b("input-b");
    readDataFromText(b, foos, &foo::b);
    return foos;
}

At this point, calling readValues() will return a container with a unison of "input-a" and "input-b"; all keys will be present, and foos with have either a or b or both.

To get the new id, all you have to do is flush the entity manager. See getNext() method below:

@Entity
@SequenceGenerator(name = "sequence", sequenceName = "mySequence")
public class SequenceFetcher
{
    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sequence")
    private long id;

    public long getId() {
        return id;
    }

    public static long getNext(EntityManager em) {
        SequenceFetcher sf = new SequenceFetcher();
        em.persist(sf);
        em.flush();
        return sf.getId();
    }
}

With jQuery

The event.which property normalizes event.keyCode and event.charCode. It is recommended to watch event.which for keyboard key input.

http://api.jquery.com/event.which/

jQuery('#input').on('keydown', function(e) {
    if( e.which == 8 || e.which == 46 ) return false;
});

Enumerations are used to represent a set of integer values.

The class keyword after the enum specifies that the enumeration is strongly typed and its enumerators are scoped. This way enum classes prevents accidental misuse of constants.

For Example:

enum class Animal{Dog, Cat, Tiger};
enum class Pets{Dog, Parrot};

Here we can not mix Animal and Pets values.

Animal a = Dog;       // Error: which DOG?    
Animal a = Pets::Dog  // Pets::Dog is not an Animal

NOW() is used to insert the current date and time in the MySQL table. All fields with datatypes DATETIME, DATE, TIME & TIMESTAMP work good with this function.

YYYY-MM-DD HH:mm:SS

Demonstration:

Following code shows the usage of NOW()

INSERT INTO auto_ins
(MySQL_Function, DateTime, Date, Time, Year, TimeStamp)
VALUES
(“NOW()”, NOW(), NOW(), NOW(), NOW(), NOW());

Here's my really quick-n-dirty one:

<!-- HTML file -->
<html ng-app="num">
  <head></head>
  <body ng-controller="numCtrl">
    <form class="digits" name="digits" ng-submit="getGrades()" novalidate >
      <input type="text" placeholder="digits here plz" name="nums" ng-model="nums" required ng-pattern="/^(\d)+$/" />
      <p class="alert" ng-show="digits.nums.$error.pattern">Numbers only, please.</p> 
      <br>
      <input type="text" placeholder="txt here plz" name="alpha" ng-model="alpha" required ng-pattern="/^(\D)+$/" />
      <p class="alert" ng-show="digits.alpha.$error.pattern">Text only, please.</p>
      <br>
      <input class="btn" type="submit" value="Do it!" ng-disabled="!digits.$valid" />
    </form>
  </body>
</html>

// Javascript file
var app = angular.module('num', ['ngResource']);
app.controller('numCtrl', function($scope, $http){
  $scope.digits = {};
});

This requires you include the angular-resource library for persistent bindings to the fields for validation purposes.

Working example here

Works like a champ in 1.2.0-rc.3+. Modify the regex and you should be all set. Perhaps something like /^(\d|\.)+$/ ? As always, validate server-side when you're done.

2018 now. You don't need any extensions for auto-imports in Javascript (as long as you have checkjs: true in your jsconfig.json file) and TypeScript.

There are two types of auto imports: the add missing import quick fix which shows up as a lightbulb on errors:

And the auto import suggestions. These show up a suggestion items as you type. Accepting an auto import suggestion automatically adds the import at the top of the file

Both should work out of the box with JavaScript and TypeScript. If auto imports still do not work for you, please open an issue

Take a look at the Dojo Object Harness (DOH) unit test framework which is pretty much framework independent harness for JavaScript unit testing and doesn't have any Dojo dependencies. There is a very good description of it at Unit testing Web 2.0 applications using the Dojo Objective Harness.

If you want to automate the UI testing (a sore point of many developers) — check out doh.robot (temporary down. update: other link http://dojotoolkit.org/reference-guide/util/dohrobot.html ) and dijit.robotx (temporary down). The latter is designed for an acceptance testing. Update:

Referenced articles explain how to use them, how to emulate a user interacting with your UI using mouse and/or keyboard, and how to record a testing session, so you can "play" it later automatically.

I spent a lot of time trying different answers all around the internet, and I suspect the reasons why one thing works for some people and not for others is due to very small weird differences in application. For context, I needed to read in file names from a csv file that had strange and/or unmappable unicode characters and write them to a new csv file. For what it's worth, here's what worked for me:

s = '\u00e7\u00a3\u0085\u00e5\u008d\u0095' # csv freaks if you try to write this
s = repr(s.encode('utf-8', 'ignore'))[2:-1]

Object initializers were introduced in C# 3.0, check which framework version you are targeting.

Overview of C# 3.0

Just use the std:: qualifier in front of string in your header files.

In fact, you should use it for istream and ostream also - and then you will need #include <iostream> at the top of your header file to make it more self contained.

xxx.match(yyy, 'g').length

You can create a new date object with todays date using the following code:

var d = new Date();_x000D_
    console.log(d);

If you want to create a date a specific time, you can pass the new Date constructor arguments

 var d = new Date(2014);_x000D_
    console.log(d)

// => Wed Dec 31 1969 16:00:02 GMT-0800 (PST)

If you want to take todays date and add a year, you can first create a date object, access the relevant properties, and then use them to create a new date object

var d = new Date();_x000D_
    var year = d.getFullYear();_x000D_
    var month = d.getMonth();_x000D_
    var day = d.getDate();_x000D_
    var c = new Date(year + 1, month, day);_x000D_
    console.log(c);

// => Tue Oct 11 2016 00:00:00 GMT-0700 (PDT)

You can read more about the methods on the date object on MDN

AppCompat tinting attributs:

First, you should take a look to appCompat lib article there and to different attributs you can set:

colorPrimary: The primary branding color for the app. By default, this is the color applied to the action bar background.

colorPrimaryDark: Dark variant of the primary branding color. By default, this is the color applied to the status bar (via statusBarColor) and navigation bar (via navigationBarColor).

colorAccent: Bright complement to the primary branding color. By default, this is the color applied to framework controls (via colorControlActivated).

colorControlNormal: The color applied to framework controls in their normal state.

colorControlActivated: The color applied to framework controls in their activated (ex. checked, switch on) state.

colorControlHighlight: The color applied to framework control highlights (ex. ripples, list selectors).

colorButtonNormal: The color applied to framework buttons in their normal state.

colorSwitchThumbNormal: The color applied to framework switch thumbs in their normal state. (switch off)

If all custom switches are the same in a single activity:

With previous attributes you can define your own theme for each activity:

<style name="Theme.MyActivityTheme" parent="Theme.AppCompat.Light">
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">@color/my_awesome_color</item>

    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/my_awesome_darker_color</item>

    <!-- colorAccent is used as the default value for colorControlActivated,
         which is used to tint widgets -->
    <item name="colorAccent">@color/accent</item>

    <!-- You can also set colorControlNormal, colorControlActivated
         colorControlHighlight, and colorSwitchThumbNormal. -->

</style>

and :

<manifest>
...
    <activity
        android:name=".MainActivity" 
        android:theme="@style/Theme.MyActivityTheme">
    </activity>
...
</manifest>

If you want to have differents custom switches in a single activity:

As widget tinting in appcompat works by intercepting any layout inflation and inserting a special tint-aware version of the widget in its place (See Chris Banes post about it) you can not apply a custom style to each switch of your layout xml file. You have to set a custom Context that will tint switch with right colors.

--

To do so for pre-5.0 you need to create a Context that overlays global theme with customs attributs and then create your switches programmatically:

ContextThemeWrapper ctw = ContextThemeWrapper(getActivity(), R.style.Color1SwitchStyle); 
SwitchCompat sc = new SwitchCompat(ctw)

As of AppCompat v22.1 you can use the following XML to apply a theme to the switch widget:

<RelativeLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    ...>

    <android.support.v7.widget.SwitchCompat
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:theme="@style/Color1SwitchStyle"/>

Your custom switch theme:

<style name="Color1SwitchStyle">
    <item name="colorControlActivated">@color/my_awesome_color</item>
</style>

--

On Android 5.0 it looks like a new view attribut comes to life : android:theme (same as one use for activity declaration in manifest). Based on another Chris Banes post, with the latter you should be able to define a custom theme directly on a view from your layout xml:

<android.support.v7.widget.SwitchCompat
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/Color1SwitchStyle"/>

To change the track color of a SwitchCompat

Thanks to vine'th I complete my answer with a link to SO answer that explains how to specify the Foreground of the Track when Switch is Off, it's there.

It's possible to inject instance of ApplicationContext class by using SpringClassRule and SpringMethodRule rules. It might be very handy if you would like to use another non-Spring runners. Here's an example:

@ContextConfiguration(classes = BeanConfiguration.class)
public static class SpringRuleUsage {

    @ClassRule
    public static final SpringClassRule springClassRule = new SpringClassRule();

    @Rule
    public final SpringMethodRule springMethodRule = new SpringMethodRule();

    @Autowired
    private ApplicationContext context;

    @Test
    public void shouldInjectContext() {
    }
}

In addition to all of the great answers, there is a concept called lazy loading:

Lazy loading is a design pattern commonly used in computer programming to defer initialization of an object until the point at which it is needed.

Using it properly, you can reduce the loading time of your application. And Kotlin way of it's implementation is by lazy() which loads the needed value to your variable whenever it's needed.

But lateinit is used when you are sure a variable won't be null or empty and will be initialized before you use it -e.g. in onResume() method for android- and so you don't want to declare it as a nullable type.

Most of the answers suggest either using a loop with equals to check if the enum exists or using try/catch with enum.valueOf(). I wanted to know which method is faster and tried it. I am not very good at benchmarking, so please correct me if I made any mistakes.

Heres the code of my main class:

    package enumtest;

public class TestMain {

    static long timeCatch, timeIterate;
    static String checkFor;
    static int corrects;

    public static void main(String[] args) {
        timeCatch = 0;
        timeIterate = 0;
        TestingEnum[] enumVals = TestingEnum.values();
        String[] testingStrings = new String[enumVals.length * 5];
        for (int j = 0; j < 10000; j++) {
            for (int i = 0; i < testingStrings.length; i++) {
                if (i % 5 == 0) {
                    testingStrings[i] = enumVals[i / 5].toString();
                } else {
                    testingStrings[i] = "DOES_NOT_EXIST" + i;
                }
            }

            for (String s : testingStrings) {
                checkFor = s;
                if (tryCatch()) {
                    ++corrects;
                }
                if (iterate()) {
                    ++corrects;
                }
            }
        }

        System.out.println(timeCatch / 1000 + "us for try catch");
        System.out.println(timeIterate / 1000 + "us for iterate");
        System.out.println(corrects);
    }

    static boolean tryCatch() {
        long timeStart, timeEnd;
        timeStart = System.nanoTime();
        try {
            TestingEnum.valueOf(checkFor);
            return true;
        } catch (IllegalArgumentException e) {
            return false;
        } finally {
            timeEnd = System.nanoTime();
            timeCatch += timeEnd - timeStart;
        }

    }

    static boolean iterate() {
        long timeStart, timeEnd;
        timeStart = System.nanoTime();
        TestingEnum[] values = TestingEnum.values();
        for (TestingEnum v : values) {
            if (v.toString().equals(checkFor)) {
                timeEnd = System.nanoTime();
                timeIterate += timeEnd - timeStart;
                return true;
            }
        }
        timeEnd = System.nanoTime();
        timeIterate += timeEnd - timeStart;
        return false;
    }
}

This means, each methods run 50000 times the lenght of the enum I ran this test multiple times, with 10, 20, 50 and 100 enum constants. Here are the results:

• 10: try/catch: 760ms | iteration: 62ms
• 20: try/catch: 1671ms | iteration: 177ms
• 50: try/catch: 3113ms | iteration: 488ms
• 100: try/catch: 6834ms | iteration: 1760ms

These results were not exact. When executing it again, there is up to 10% difference in the results, but they are enough to show, that the try/catch method is far less efficient, especially with small enums.

Atomic property can be accessed by only one thread at a time. It is thread safe. Default is atomic .Please note that there is no keyword atomic

Nonatomic means multiple thread can access the item .It is thread unsafe

So one should be very careful while using atomic .As it affect the performance of your code

Yes, it is possible since lists are mutable.

Look at the built-in enumerate() function to get an idea how to iterate over the list and find each entry's index (which you can then use to assign to the specific list item).

Use $dirty flag to show the error only after user interacted with the input:

<div>
  <input type="email" name="email" ng-model="user.email" required />
  <span ng-show="form.email.$dirty && form.email.$error.required">Email is required</span>
</div>

If you want to trigger the errors only after the user has submitted the form than you may use a separate flag variable as in:

<form ng-submit="submit()" name="form" ng-controller="MyCtrl">
  <div>
    <input type="email" name="email" ng-model="user.email" required />
    <span ng-show="(form.email.$dirty || submitted) && form.email.$error.required">
      Email is required
    </span>
  </div>

  <div>
    <button type="submit">Submit</button>
  </div>
</form>

function MyCtrl($scope){
  $scope.submit = function(){
    // Set the 'submitted' flag to true
    $scope.submitted = true;
    // Send the form to server
    // $http.post ...
  } 
};

Then, if all that JS inside ng-showexpression looks too much for you, you can abstract it into a separate method:

function MyCtrl($scope){
  $scope.submit = function(){
    // Set the 'submitted' flag to true
    $scope.submitted = true;
    // Send the form to server
    // $http.post ...
  }

  $scope.hasError = function(field, validation){
    if(validation){
      return ($scope.form[field].$dirty && $scope.form[field].$error[validation]) || ($scope.submitted && $scope.form[field].$error[validation]);
    }
    return ($scope.form[field].$dirty && $scope.form[field].$invalid) || ($scope.submitted && $scope.form[field].$invalid);
  };

};

<form ng-submit="submit()" name="form">
  <div>
    <input type="email" name="email" ng-model="user.email" required />
    <span ng-show="hasError('email', 'required')">required</span>
  </div>

  <div>
    <button type="submit">Submit</button>
  </div>
</form>

Hope it helps.

We were able to solve a similar issue here using Oracle LISTAGG. There was a point where what we were grouping on exceeded the 4K limit but this was easily solved by having the first dataset take the first 15 items to aggregate, each of which have a 256K limit.

More info: We have projects, which have change orders, which in turn have explanations. Why the database is set up to take change text in chunks of 256K limits is not known but its one of the design constraints. So the application that feeds change explanations into the table stops at 254K and inserts, then gets the next set of text and if > 254K generates another row, etc. So we have a project to a change order, a 1:1. Then we have these as 1:n for explanations. LISTAGG concatenates all these. We have RMRKS_SN values, 1 for each remark and/or for each 254K of characters.

The largest RMRKS_SN was found to be 31, so I did the first dataset pulling SN 0 to 15, the 2nd dataset 16 to 30 and the last dataset 31 to 45 -- hey, let's plan on someone adding a LOT of explanation to some change orders!

In the SQL report, the Tablix ties to the first dataset. To get the other data, here's the expression:

=First(Fields!NON_STD_TXT.Value, "DataSet_EXPLAN") & First(Fields!NON_STD_TXT.Value, "ds_EXPLAN_SN_16_TO_30") & First(Fields!NON_STD_TXT.Value, "ds_EXPLAN_SN_31_TO_45")

For us, we have to have DB Group create functions, etc. because of security constraints. So with a bit of creativity, we didn't have to do a User Aggregate or a UDF.

If your application has some sort of SN to aggregate by, this method should work. I don't know what the equivalent TSQL is -- we're fortunate to be dealing with Oracle for this report, for which LISTAGG is a Godsend.

The code is:

SELECT
LT.C_O_NBR AS LT_CO_NUM,
RT.C_O_NBR AS RT_CO_NUM,
LT.STD_LN_ITM_NBR, 
RT.NON_STD_LN_ITM_NBR,
RT.NON_STD_PRJ_NBR, 
LT.STD_PRJ_NBR, 
NVL(LT.PRPSL_LN_NBR, RT.PRPSL_LN_NBR) AS PRPSL_LN_NBR,
LT.STD_CO_EXPL_TXT AS STD_TXT,
LT.STD_CO_EXPLN_T, 
LT.STD_CO_EXPL_SN, 
RT.NON_STD_CO_EXPLN_T,
LISTAGG(RT.RMRKS_TXT_FLD, '') 
    WITHIN GROUP(ORDER BY RT.RMRKS_SN) AS NON_STD_TXT

FROM ...

    WHERE RT.RMRKS_SN BETWEEN 0 AND 15

GROUP BY 
    LT.C_O_NBR,
    RT.C_O_NBR,
    ...

And in the other 2 datasets just select the LISTAGG only for the subqueries in the FROM:

SELECT
LISTAGG(RT.RMRKS_TXT_FLD, '') 
    WITHIN GROUP(ORDER BY RT.RMRKS_SN) AS NON_STD_TXT

FROM ...

WHERE RT.RMRKS_SN BETWEEN 31 AND 45

...

... and so on.

One important missing bit is, what is the correct way to resolve this issue?

As Greg explained, the root problem here is that a base class constructor would invoke the virtual member before the derived class has been constructed.

The following code, taken from MSDN's constructor design guidelines, demonstrates this issue.

public class BadBaseClass
{
    protected string state;

    public BadBaseClass()
    {
        this.state = "BadBaseClass";
        this.DisplayState();
    }

    public virtual void DisplayState()
    {
    }
}

public class DerivedFromBad : BadBaseClass
{
    public DerivedFromBad()
    {
        this.state = "DerivedFromBad";
    }

    public override void DisplayState()
    {   
        Console.WriteLine(this.state);
    }
}

When a new instance of DerivedFromBad is created, the base class constructor calls to DisplayState and shows BadBaseClass because the field has not yet been update by the derived constructor.

public class Tester
{
    public static void Main()
    {
        var bad = new DerivedFromBad();
    }
}

An improved implementation removes the virtual method from the base class constructor, and uses an Initialize method. Creating a new instance of DerivedFromBetter displays the expected "DerivedFromBetter"

public class BetterBaseClass
{
    protected string state;

    public BetterBaseClass()
    {
        this.state = "BetterBaseClass";
        this.Initialize();
    }

    public void Initialize()
    {
        this.DisplayState();
    }

    public virtual void DisplayState()
    {
    }
}

public class DerivedFromBetter : BetterBaseClass
{
    public DerivedFromBetter()
    {
        this.state = "DerivedFromBetter";
    }

    public override void DisplayState()
    {
        Console.WriteLine(this.state);
    }
}

After installing composer using the command curl -sS https://getcomposer.org/installer | php just run a sudo apt-get update then reinstall curl with sudo apt-get install php5-curl. Then composer's installation process should work so you can finally run php composer.phar install to get the dependencies listed in your composer.json file.

No, since the new throw is not in the try block directly.

just override onCreateOptionsMenu like this in your MainPage.java

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main_menu, menu);
    return true;
}

1. Check for your configuration files by running the aforementioned command: sudo nginx -t.

2. Check for port conflicts. For instance, if apache2 (ps waux | grep apache2) or any other service is using the same ports configured for nginx (say port 80) the service will not start and will fail silently (err... the cousin of my friend had this problem...)

Done by having it like that:

view = inflater.inflate(R.layout.entry_detail, container, false);
TextView tp1= (TextView) view.findViewById(R.id.tp1);
LinearLayout layone= (LinearLayout) view.findViewById(R.id.layone);
tp1.setVisibility(View.VISIBLE);
layone.setVisibility(View.VISIBLE);

You can also use this method:

<input type="text" class="@(@mvccondition ? "true-class" : "false-class")">

Try this .. Good luck Thanks.

Looks like you called it 'ant build..xml'. ant automatically choose a file build.xml in the current directory, so it is enough to call 'ant' (if a default-target is defined) or 'ant target' (the target named target will be called).

With the call 'ant -p' you get a list of targets defined in your build.xml.

Edit: In the comment is shown the call 'ant -verbose build.xml'. To be correct, this has to be called as 'ant -verbose'. The file build.xml in the current directory will be used automatically. If it is needed to explicitly specify the buildfile (because it's name isn't build.xml for example), you have to specify the buildfile with the '-f'-option: 'ant -verbose -f build.xml'. I hope this helps.

There is no reason against using a single block for multiple operations, since any thrown exception will prevent the execution of further operations after the failed one. At least as long as you can conclude which operation failed from the exception caught. That is as long as it is fine if some operations are not processed.

However I'd say that returning the exception makes only limited sense. A return value of a function should be the expected result of some action, not the exception. If you need to react on the exception in the calling scope then either do not catch the exception here inside your function, but in the calling scope or re-throw the exception for later processing after having done some debug logging and the like.

This is the simplest way to plot an ROC curve, given a set of ground truth labels and predicted probabilities. Best part is, it plots the ROC curve for ALL classes, so you get multiple neat-looking curves as well

import scikitplot as skplt
import matplotlib.pyplot as plt

y_true = # ground truth labels
y_probas = # predicted probabilities generated by sklearn classifier
skplt.metrics.plot_roc_curve(y_true, y_probas)
plt.show()

Here's a sample curve generated by plot_roc_curve. I used the sample digits dataset from scikit-learn so there are 10 classes. Notice that one ROC curve is plotted for each class.

Disclaimer: Note that this uses the scikit-plot library, which I built.

Lets say to want to make default version as 10.19.0.

nvm alias default v10.19.0

But it will give following error

! WARNING: Version 'v10.19.0' does not exist.
default -> v10.19.0 (-> N/A)

In That case you need to run two commands in the following order

# Install the version that you would like 
nvm install 10.19.0

# Set 10.19.0 (or another version) as default
nvm alias default 10.19.0

Here's a more generic version of the solution above from @herbertD :

private void resizeView(View view, int newWidth, int newHeight) { 
    try { 
        Constructor<? extends LayoutParams> ctor = view.getLayoutParams().getClass().getDeclaredConstructor(int.class, int.class); 
        view.setLayoutParams(ctor.newInstance(newWidth, newHeight));   
    } catch (Exception e) { 
        e.printStackTrace(); 
    }
}

I would say that you should put styles that won't change into a regular style attribute, and conditional/scope styles into an ng-style attribute. Also, string keys are not necessary. For hyphen-delimited CSS keys, use camelcase.

<div ng-style="{backgroundColor: data.backgroundCol}" style="width:20px; height:20px; margin-top:10px; border:solid 1px black;"></div>

parseInt(string) will convert a string containing non-numeric characters to a number, as long as the string begins with numeric characters

'10px' => 10

Number(string) will return NaN if the string contains any non-numeric characters

Without converting to a string you could try:

Math.Ceiling(Math.Log10(n));

Correction following ysap's comment:

Math.Floor(Math.Log10(n) + 1);

Something like this:

for (/* stuff */)
{
    var x = '<option value="' + col + '" '
        + (col === 'screwdriver' ? 'selected' : '')
        + '>Very roomy</option>';
    // snip...
}

The docs give a fair indicator of what's required., however requests allow us to skip a few steps:

You only need to install the security package extras (thanks @admdrew for pointing it out)

$ pip install requests[security]

or, install them directly:

$ pip install pyopenssl ndg-httpsclient pyasn1

Requests will then automatically inject pyopenssl into urllib3

If you're on ubuntu, you may run into trouble installing pyopenssl, you'll need these dependencies:

$ apt-get install libffi-dev libssl-dev

What are the steps for that? where is AppCompat located?

Download the support library here:

http://developer.android.com/tools/support-library/setup.html

If you are using Eclipse:

Go to the tabs at the top and select ( Windows -> Android SDK Manager ). Under the 'extras' section, check 'Android Support Library' and check it for installation.

After that, the AppCompat library can be found at:

android-sdk/extras/android/support/v7/appcompat

You need to reference this AppCompat library in your Android project.

Import the library into Eclipse.

1. Right click on your Android project.
2. Select properties.
3. Click 'add...' at the bottom to add a library.
4. Select the support library
5. Clean and rebuild your project.
