This is an old thread, but I'm responding because it still appears high in the list of search results. Now that the future has arrived, you can use the :nth-child pseudo-selector.

p:nth-child(1) { color: blue; }
p.myclass1:nth-child(1) { color: red; }
p.myclass2:nth-child(1) { color: green; }

The :nth-child pseudo-selector is powerful - the parentheses accept formulas as well as numbers.

You can implement Drag&Drop in WinForms and WPF.

• WinForm (Drag from app window)

You should add mousemove event:

private void YourElementControl_MouseMove(object sender, MouseEventArgs e)

    {
     ...
         if (e.Button == MouseButtons.Left)
         {
                 DoDragDrop(new DataObject(DataFormats.FileDrop, new string[] { PathToFirstFile,PathToTheNextOne }), DragDropEffects.Move);
         }
     ...
    }

• WinForm (Drag to app window)

You should add DragDrop event:

private void YourElementControl_DragDrop(object sender, DragEventArgs e)

    {
       ...
       foreach (string path in (string[])e.Data.GetData(DataFormats.FileDrop))
            {
                File.Copy(path, DirPath + Path.GetFileName(path));
            }
       ...
    }

I am newbie and most of the code is from google search. I got my pdf download working with the code below (trial and error play). Thank you for code tips (xhrFields) above.

$.ajax({
            cache: false,
            type: 'POST',
            url: 'yourURL',
            contentType: false,
            processData: false,
            data: yourdata,
             //xhrFields is what did the trick to read the blob to pdf
            xhrFields: {
                responseType: 'blob'
            },
            success: function (response, status, xhr) {

                var disposition = xhr.getResponseHeader('Content-Disposition');

                 if (disposition) {

                        //   IE workaround for "HTML7007: One or more blob URLs were revoked by closing the blob for which they were created. These URLs will no longer resolve as the data backing the URL has been freed."

                    } else {
                        var URL = window.URL || window.webkitURL;
                        var downloadUrl = URL.createObjectURL(blob);

                        if (filename) { 
                            // use HTML5 a[download] attribute to specify filename
                            var a = document.createElement("a");

                            // safari doesn't support this yet

                                document.body.appendChild(a);
                                a.target = "_blank";
                                a.click();
                            }
                        } else {
                            window.location = downloadUrl;
                        }
                    }   

                } catch (ex) {
                    console.log(ex);
                } 
            }
        });

The original checked attribute (HTML 4 and before) did not require a value on it - if it existed, the element was "checked", if not, it wasn't.

This, however is not valid for XHTML that followed HTML 4.

The standard proposed to use checked="checked" as a condition for true - so both ways you posted end up doing the same thing.

It really doesn't matter which one you use - use the one that makes most sense to you and stick to it (or agree with your team which way to go).

Command find_package has two modes: Module mode and Config mode. You are trying to use Module mode when you actually need Config mode.

Module mode

Find<package>.cmake file located within your project. Something like this:

CMakeLists.txt
cmake/FindFoo.cmake
cmake/FindBoo.cmake

CMakeLists.txt content:

list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/cmake")
find_package(Foo REQUIRED) # FOO_INCLUDE_DIR, FOO_LIBRARIES
find_package(Boo REQUIRED) # BOO_INCLUDE_DIR, BOO_LIBRARIES

include_directories("${FOO_INCLUDE_DIR}")
include_directories("${BOO_INCLUDE_DIR}")
add_executable(Bar Bar.hpp Bar.cpp)
target_link_libraries(Bar ${FOO_LIBRARIES} ${BOO_LIBRARIES})

Note that CMAKE_MODULE_PATH has high priority and may be usefull when you need to rewrite standard Find<package>.cmake file.

Config mode (install)

<package>Config.cmake file located outside and produced by install command of other project (Foo for example).

foo library:

> cat CMakeLists.txt 
cmake_minimum_required(VERSION 2.8)
project(Foo)

add_library(foo Foo.hpp Foo.cpp)
install(FILES Foo.hpp DESTINATION include)
install(TARGETS foo DESTINATION lib)
install(FILES FooConfig.cmake DESTINATION lib/cmake/Foo)

Simplified version of config file:

> cat FooConfig.cmake 
add_library(foo STATIC IMPORTED)
find_library(FOO_LIBRARY_PATH foo HINTS "${CMAKE_CURRENT_LIST_DIR}/../../")
set_target_properties(foo PROPERTIES IMPORTED_LOCATION "${FOO_LIBRARY_PATH}")

By default project installed in CMAKE_INSTALL_PREFIX directory:

> cmake -H. -B_builds
> cmake --build _builds --target install
-- Install configuration: ""
-- Installing: /usr/local/include/Foo.hpp
-- Installing: /usr/local/lib/libfoo.a
-- Installing: /usr/local/lib/cmake/Foo/FooConfig.cmake

Config mode (use)

Use find_package(... CONFIG) to include FooConfig.cmake with imported target foo:

> cat CMakeLists.txt 
cmake_minimum_required(VERSION 2.8)
project(Boo)

# import library target `foo`
find_package(Foo CONFIG REQUIRED)

add_executable(boo Boo.cpp Boo.hpp)
target_link_libraries(boo foo)
> cmake -H. -B_builds -DCMAKE_VERBOSE_MAKEFILE=ON
> cmake --build _builds
Linking CXX executable Boo
/usr/bin/c++ ... -o Boo /usr/local/lib/libfoo.a

Note that imported target is highly configurable. See my answer.

• Example

Here are the details of what works for an EC2 instance:

scp -i /path/to/whatever.pem /users/me/path-to-file [email protected]:~

Few notes for beginning:

1. Note the spaces between the three parameters given after the -i
2. scp stands for secure copy protocol. Knowing the words makes it easier to remember the command.
3. -i dictates that you need to give the .pem file as the next param. If there is no -i, than you do not need a .pem.
4. Note the :~ at the end of the destination for the EC2 instance.

You can add a column to your data using various techniques. The quotes below come from the "Details" section of the relevant help text, [[.data.frame.

Data frames can be indexed in several modes. When [ and [[ are used with a single vector index (x[i] or x[[i]]), they index the data frame as if it were a list.

my.dataframe["new.col"] <- a.vector
my.dataframe[["new.col"]] <- a.vector

The data.frame method for $, treats x as a list

my.dataframe$new.col <- a.vector

When [ and [[ are used with two indices (x[i, j] and x[[i, j]]) they act like indexing a matrix

my.dataframe[ , "new.col"] <- a.vector

Since the method for data.frame assumes that if you don't specify if you're working with columns or rows, it will assume you mean columns.

For your example, this should work:

# make some fake data
your.df <- data.frame(no = c(1:4, 1:7, 1:5), h_freq = runif(16), h_freqsq = runif(16))

# find where one appears and 
from <- which(your.df$no == 1)
to <- c((from-1)[-1], nrow(your.df)) # up to which point the sequence runs

# generate a sequence (len) and based on its length, repeat a consecutive number len times
get.seq <- mapply(from, to, 1:length(from), FUN = function(x, y, z) {
            len <- length(seq(from = x[1], to = y[1]))
            return(rep(z, times = len))
         })

# when we unlist, we get a vector
your.df$group <- unlist(get.seq)
# and append it to your original data.frame. since this is
# designating a group, it makes sense to make it a factor
your.df$group <- as.factor(your.df$group)


   no     h_freq   h_freqsq group

a WebMethod which requires a ContextKey,

[WebMethod]
public string[] GetValues(string prefixText, int count, string contextKey)

when this key is not set, got the exception.

Fixing it by assigning AutoCompleteExtender's key.

ac.ContextKey = "myKey";

Just add another join:

SELECT dashboard_data.headline,
       dashboard_data.message,
       dashboard_messages.image_id,
       images.filename 
FROM dashboard_data 
    INNER JOIN dashboard_messages
            ON dashboard_message_id = dashboard_messages.id 
    INNER JOIN images
            ON dashboard_messages.image_id = images.image_id

Try something like this instead;

string illegal = "\"M\"\\a/ry/ h**ad:>> a\\/:*?\"| li*tt|le|| la\"mb.?";
string invalid = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());

foreach (char c in invalid)
{
    illegal = illegal.Replace(c.ToString(), ""); 
}

But I have to agree with the comments, I'd probably try to deal with the source of the illegal paths, rather than try to mangle an illegal path into a legitimate but probably unintended one.

Edit: Or a potentially 'better' solution, using Regex's.

string illegal = "\"M\"\\a/ry/ h**ad:>> a\\/:*?\"| li*tt|le|| la\"mb.?";
string regexSearch = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());
Regex r = new Regex(string.Format("[{0}]", Regex.Escape(regexSearch)));
illegal = r.Replace(illegal, "");

Still, the question begs to be asked, why you're doing this in the first place.

It is possible to roll your own version of PHP's die:

function die(msg)
{
    throw msg;
}

function test(arg1)
{
    arg1 = arg1 || die("arg1 is missing"); 
}

test();

JSFiddle Example

I usually choose a ternary operator when I'd have a lot of duplicate code otherwise.

if (a > 0)
    answer = compute(a, b, c, d, e);
else
    answer = compute(-a, b, c, d, e);

With a ternary operator, this could be accomplished with the following.

answer = compute(a > 0 ? a : -a, b, c, d, e); 

let clickTimes = 0;
let timer = null;
roundBox.click = function (e) {
  clearTimeout(timer);
  timer = setTimeout(() => { // ????
    console.log("single click");
  }, 600);
  clickTimes++;

  if (clickTimes == 2) { // ??
    clearTimeout(timer);
    clickTimes = 0;
    console.log("double click");
    toggleExpanded(id);
  }
}

Getting month range with .Net API (just another way):

DateTime date = ...
var firstDayOfMonth = new DateTime(date.Year, date.Month, 1);
var lastDayOfMonth = new DateTime(date.Year, date.Month, DateTime.DaysInMonth(date.Year, date.Month));

If you need to position an element relative to its containing element first you need to add position: relative to the container element. The child element you want to position relatively to the parent has to have position: absolute. The way that absolute positioning works is that it is done relative to the first relatively (or absolutely) positioned parent element. In case there is no relatively positioned parent, the element will be positioned relative to the root element (directly to the HTML element).

So if you want to position your child element to the top left of the parent container, you should do this:

.parent {
  position: relative;
} 

.child {
  position: absolute;
  top: 0;
  left: 0;  
}

You will benefit greatly from reading this article. Hope this helps!

For Sybase ASE, sp_columns table_name will return all the table metadata you are looking for.

What you could do, is to make sure to pass the parent form as the owner when showing the child form:

  Form newForm = new ChildForm();
  newForm.Show(this);

Then, in the child form, set up event handlers for the Activated and Deactivate events:

private void Form_Activated(object sender, System.EventArgs e)
{
    if (this.Owner != null)
    {
        this.Owner.Enabled = false; 
    }
}

private void Form_Deactivate(object sender, System.EventArgs e)
{
    if (this.Owner != null)
    {
        this.Owner.Enabled = true;
    }
}

However, this will result in a truly wierd behaviour; while you will not be able to go back and interact with the parent form immediately, activating any other application will enable it, and then the user can interact with it.

If you want to make the child form modal, use ShowDialog instead:

  Form newForm = new ChildForm();
  newForm.ShowDialog(this);

I had this very similar error as following.

C:\wamp\www\myrepository [master]> git push
fatal: unable to access 'https://github.com/myaccount/myrepository.git/': Couldn't resolve host 'github.com'

Actually, the prompt message has told us where's wrong.

https://github.com/myaccount/myrepository.git/

When I check my github, I found my github repository's HTTPS url is

https://github.com/myaccount/myrepository.git

I don't know how this happened. The wrong url has been set up by installed Git Shell automatically.

Once I remove the '/' at the end, I can push successfully.

Starting from C++23 you can use std::string::contains

#include <string>

const auto haystack = std::string("haystack with needles");
const auto needle = std::string("needle");

if (haystack.contains(needle))
{
    // found!
}

You could use a negative look-ahead assertion:

^(?!tbd_).+

Or a negative look-behind assertion:

(^.{1,3}$|^.{4}(?<!tbd_).*)

Or just plain old character sets and alternations:

^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

from lxml import etree
from bs4 import BeautifulSoup
soup = BeautifulSoup(open('path of your localfile.html'),'html.parser')
dom = etree.HTML(str(soup))
print dom.xpath('//*[@id="BGINP01_S1"]/section/div/font/text()')

Above used the combination of Soup object with lxml and one can extract the value using xpath

You can use MessageDigest in the following way:

public static String getSHA256(String data){
    StringBuffer sb = new StringBuffer();
    try{
        MessageDigest md = MessageDigest.getInstance("SHA-256");
        md.update(data.getBytes());
        byte byteData[] = md.digest();

        for (int i = 0; i < byteData.length; i++) {
         sb.append(Integer.toString((byteData[i] & 0xff) + 0x100, 16).substring(1));
        }
    } catch(Exception e){
        e.printStackTrace();
    }
    return sb.toString();
}

Use WebClient.DownloadFile:

using (WebClient client = new WebClient())
{
    client.DownloadFile("http://csharpindepth.com/Reviews.aspx", 
                        @"c:\Users\Jon\Test\foo.txt");
}

Try setting these values, it solves problem in fast-cgi

fastcgi_buffer_size 16k;
fastcgi_buffers 4 16k;

In VBA, the != operator is the Not operator, like this:

If Not strTest = "" Then ...

Because char is by default signed declared that means the range of the variable is

-127 to +127>

your value is overflowed. To get the desired value you have to declared the unsigned modifier. the modifier's (unsigned) range is:

 0 to 255

to get the the range of any data type follow the process 2^bit example charis 8 bit length to get its range just 2 ^(power) 8.

Based on Kapitán Mlíko's answer with source above, I would change it to use the following:

If your python version is 2.+, you can type below code to the terminal :

pip install seaborn

if python version is 3+, type below:

pip3 install seaborn

date command didnt provide milli seconds on OS X, so used an alias from python

millis(){  python -c "import time; print(int(time.time()*1000))"; }

OR

alias millis='python -c "import time; print(int(time.time()*1000))"'

EDIT: following the comment from @CharlesDuffy. Forking any child process takes extra time.

$ time date +%s%N
1597103627N
date +%s%N  0.00s user 0.00s system 63% cpu 0.006 total

Python is still improving it's VM start time, and it is not as fast as ahead-of-time compiled code (such as date).

On my machine, it took about 30ms - 60ms (that is 5x-10x of 6ms taken by date)

$ time python -c "import time; print(int(time.time()*1000))"
1597103899460
python -c "import time; print(int(time.time()*1000))"  0.03s user 0.01s system 83% cpu 0.053 total

I figured awk is lightweight than python, so awk takes in the range of 6ms to 12ms (i.e. 1x to 2x of date):

$ time awk '@load "time"; BEGIN{print int(1000 * gettimeofday())}'
1597103729525
awk '@load "time"; BEGIN{print int(1000 * gettimeofday())}'  0.00s user 0.00s system 74% cpu 0.010 total

There should be three pages here:

1. Initial login page with a form that asks for your username, but not your password.
2. You didn't mention this one, but I'd check whether the client computer is recognized, and if not, then challenge the user with either a CAPTCHA or else a security question. Otherwise the phishing site can simply use the tendered username to query the real site for the security image, which defeats the purpose of having a security image. (A security question is probably better here since with a CAPTCHA the attacker could have humans sitting there answering the CAPTCHAs to get at the security images. Depends how paranoid you want to be.)
3. A page after that that displays the security image and asks for the password.

I don't see this short, linear flow being sufficiently complex to warrant using Spring Web Flow.

I would just use straight Spring Web MVC for steps 1 and 2. I wouldn't use Spring Security for the initial login form, because Spring Security's login form expects a password and a login processing URL. Similarly, Spring Security doesn't provide special support for CAPTCHAs or security questions, so you can just use Spring Web MVC once again.

You can handle step 3 using Spring Security, since now you have a username and a password. The form login page should display the security image, and it should include the user-provided username as a hidden form field to make Spring Security happy when the user submits the login form. The only way to get to step 3 is to have a successful POST submission on step 1 (and 2 if applicable).

To parallelize a simple for loop, joblib brings a lot of value to raw use of multiprocessing. Not only the short syntax, but also things like transparent bunching of iterations when they are very fast (to remove the overhead) or capturing of the traceback of the child process, to have better error reporting.

Disclaimer: I am the original author of joblib.

Change the port 80 to port 8080 and restart all services and access like localhost:8080/

It will work fine.

This is how I delete files

if ((System.IO.File.Exists(fileName)))
                {
                    System.IO.File.Delete(fileName);
}

Also make sure that the file name you are passing in your delete, is the accurate path

EDIT

You could use the following event instead as well or just use the code in this snippet and use in your method

void GridView1_SelectedIndexChanged(Object sender, EventArgs e)
  {

    // Get the currently selected row using the SelectedRow property.
    GridViewRow row = CustomersGridView.SelectedRow;

    //Debug this line and see what value is returned if it contains the full path.
    //If it does not contain the full path then add the path to the string.
    string fileName = row.Cells[0].Text 

    if(fileName != null || fileName != string.empty)
    {
       if((System.IO.File.Exists(fileName))
           System.IO.File.Delete(fileName);

     }
  }

For a search routine you should look to use Find, AutoFilter or variant array approaches. Range loops are nomally too slow, worse again if they use Select

The code below will look for the strText variable in a user selected range, it then adds any matches to a range variable rng2 which you can then further process

Option Explicit

Const strText As String = "%"

Sub ColSearch_DelRows()
    Dim rng1 As Range
    Dim rng2 As Range
    Dim rng3 As Range
    Dim cel1 As Range
    Dim cel2 As Range
    Dim strFirstAddress As String
    Dim lAppCalc As Long


    'Get working range from user
    On Error Resume Next
    Set rng1 = Application.InputBox("Please select range to search for " & strText, "User range selection", Selection.Address(0, 0), , , , , 8)
    On Error GoTo 0
    If rng1 Is Nothing Then Exit Sub

    With Application
        lAppCalc = .Calculation
        .ScreenUpdating = False
        .Calculation = xlCalculationManual
    End With

    Set cel1 = rng1.Find(strText, , xlValues, xlPart, xlByRows, , False)

    'A range variable - rng2 - is used to store the range of cells that contain the string being searched for
    If Not cel1 Is Nothing Then
        Set rng2 = cel1
        strFirstAddress = cel1.Address
        Do
            Set cel1 = rng1.FindNext(cel1)
            Set rng2 = Union(rng2, cel1)
        Loop While strFirstAddress <> cel1.Address
    End If

    If Not rng2 Is Nothing Then
        For Each cel2 In rng2
            Debug.Print cel2.Address & " contained " & strText
        Next
    Else
        MsgBox "No " & strText
    End If

    With Application
        .ScreenUpdating = True
        .Calculation = lAppCalc
    End With

End Sub

They don't exist in MySQL do they? Just use a temp table:

CREATE PROCEDURE my_proc () BEGIN 

CREATE TEMPORARY TABLE TempTable (myid int, myfield varchar(100)); 
INSERT INTO TempTable SELECT tblid, tblfield FROM Table1; 

/* Do some more stuff .... */

From MySQL here

"You can use the TEMPORARY keyword when creating a table. A TEMPORARY table is visible only to the current connection, and is dropped automatically when the connection is closed. This means that two different connections can use the same temporary table name without conflicting with each other or with an existing non-TEMPORARY table of the same name. (The existing table is hidden until the temporary table is dropped.)"

The following code will compare each item with other list of items using contains() method.Length of for loop must be bigger size() of bigger list then only it will compare all the values of both list.

List<String> str = new ArrayList<String>();
str.add("first");
str.add("second");
str.add("third");
List<String> str1 = new ArrayList<String>();
str1.add("first");
str1.add("second");
str1.add("third1");
for (int i = 0; i<str1.size(); i++)
{
System.out.println(str.contains(str1.get(i)));
}

Output is true true false

Use namespace

using System.Collections.Specialized;

Make instance of DataContext Class

LinqToSqlDataContext dc = new LinqToSqlDataContext();

Use

OrderedDictionary dict = dc.TableName.ToDictionary(d => d.key, d => d.value);

In order to retrieve the values use namespace

   using System.Collections;

ICollection keyCollections = dict.Keys;
ICOllection valueCollections = dict.Values;

String[] myKeys = new String[dict.Count];
String[] myValues = new String[dict.Count];

keyCollections.CopyTo(myKeys,0);
valueCollections.CopyTo(myValues,0);

for(int i=0; i<dict.Count; i++)
{
Console.WriteLine("Key: " + myKeys[i] + "Value: " + myValues[i]);
}
Console.ReadKey();

If by "list" you mean a List<T>, then the Clear method is what you want:

List<string> list = ...;
...
list.Clear();

You should get into the habit of searching the MSDN documentation on these things.

Here's how to quickly search for documentation on various bits of that type:

• List Class - provides the List<T> class itself (this is where you should've started)
• List.Clear Method - provides documentation on the method Clear
• List.Count Property - provides documentation on the property Count

All of these Google queries lists a bundle of links, but typically you want the first one that google gives you in each case.

For me it was only crashing with this error on a production environment, not on local machine; what solved it was to delete the content of /bin folder and then to regenerate it again.

Rewrite rules are pretty much written the same way with nginx: http://wiki.nginx.org/HttpRewriteModule#rewrite

Which rules are causing you trouble? I could help you translate those!

You could use a generator expression with a default value and then next it:

next((x for x in seq if predicate(x)), None)

Although for this one-liner you need to be using Python >= 2.6.

This rather popular article further discusses this issue: Cleanest Python find-in-list function?.

In C#:
Fixed with recommendation from Mike

ArrayList list = ...;
// List<object> list = ...;
foreach (object o in list) {
    if (o is int) {
        HandleInt((int)o);
    }
    else if (o is string) {
        HandleString((string)o);
    }
    ...
}

In Java:

ArrayList<Object> list = ...;
for (Object o : list) {
    if (o instanceof Integer)) {
        handleInt((Integer o).intValue());
    }
    else if (o instanceof String)) {
        handleString((String)o);
    }
    ...
}

I don't know why @Paul's reply is downvoted, but the validation against null is a good choice. Maybe a more affirmative example will make better sense:

In JavaScript a missed parameter is like a declared variable that is not initialized (just var a1;). And the equality operator converts the undefined to null, so this works great with both value types and objects, and this is how CoffeeScript handles optional parameters.

function overLoad(p1){
    alert(p1 == null); // Caution, don't use the strict comparison: === won't work.
    alert(typeof p1 === 'undefined');
}

overLoad(); // true, true
overLoad(undefined); // true, true. Yes, undefined is treated as null for equality operator.
overLoad(10); // false, false


function overLoad(p1){
    if (p1 == null) p1 = 'default value goes here...';
    //...
}

Though, there are concerns that for the best semantics is typeof variable === 'undefined' is slightly better. I'm not about to defend this since it's the matter of the underlying API how a function is implemented; it should not interest the API user.

I should also add that here's the only way to physically make sure any argument were missed, using the in operator which unfortunately won't work with the parameter names so have to pass an index of the arguments.

function foo(a, b) {
    // Both a and b will evaluate to undefined when used in an expression
    alert(a); // undefined
    alert(b); // undefined

    alert("0" in arguments); // true
    alert("1" in arguments); // false
}

foo (undefined);

So there 2 ways to create a dict :

1. my_dict = dict()

2. my_dict = {}

But out of these two options {} is more efficient than dict() plus its readable. CHECK HERE

Just complementing, I implemented this way and usually worked in my Service class

In my Service

@Override
public void onCreate()
{
    mHandler = new Handler(Looper.getMainLooper());
    mHandler.post(this);
    super.onCreate();
}

@Override
public void onDestroy() 
{
    mHandler.removeCallbacks(this);     
    super.onDestroy();
}

@Override
public void run()
{
    InciarGPSTracker();
}

Example to show last 3 digits of account number.

x = '1234567890'   
x.replace(x[:7], '')

o/p: '890'

Using the :not() pseudo class:

For selecting everything but a certain element (or elements). We can use the :not() CSS pseudo class. The :not() pseudo class requires a CSS selector as its argument. The selector will apply the styles to all the elements except for the elements which are specified as an argument.

Examples:

/* This query selects All div elements except for   */_x000D_
div:not(.foo) {_x000D_
  background-color: red;_x000D_
}_x000D_
_x000D_
_x000D_
/* Selects all hovered nav elements inside section element except_x000D_
   for the nav elements which have the ID foo*/_x000D_
section nav:hover:not(#foo) {_x000D_
  background-color: red;_x000D_
}_x000D_
_x000D_
_x000D_
/* selects all li elements inside an ul which are not odd */_x000D_
ul li:not(:nth-child(odd)) { _x000D_
  color: red;_x000D_
}

<div>test</div>_x000D_
<div class="foo">test</div>_x000D_
_x000D_
<br>_x000D_
_x000D_
<section>_x000D_
  <nav id="foo">test</nav>_x000D_
  <nav>Hover me!!!</nav>_x000D_
</section>_x000D_
<nav></nav>_x000D_
_x000D_
<br>_x000D_
_x000D_
<ul>_x000D_
  <li>1</li>_x000D_
  <li>2</li>_x000D_
  <li>3</li>_x000D_
  <li>4</li>_x000D_
  <li>5</li>_x000D_
</ul>

We can already see the power of this pseudo class, it allows us to conveniently fine tune our selectors by excluding certain elements. Furthermore, this pseudo class increases the specificity of the selector. For example:

/* This selector has a higher specificity than the #foo below */_x000D_
#foo:not(#bar) {_x000D_
  color: red;_x000D_
}_x000D_
_x000D_
/* This selector is lower in the cascade but is overruled by the style above */_x000D_
#foo {_x000D_
  color: green;_x000D_
}

<div id="foo">"Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor_x000D_

I've created a little Powershell function to emulate MSDOS pause. This handles whether running Powershell ISE or non ISE. (ReadKey does not work in powershell ISE). When running Powershell ISE, this function opens a Windows MessageBox. This can sometimes be confusing, because the MessageBox does not always come to the forefront. Anyway, here it goes:

Usage: pause "Press any key to continue"

Function definition:

Function pause ($message)
{
    # Check if running Powershell ISE
    if ($psISE)
    {
        Add-Type -AssemblyName System.Windows.Forms
        [System.Windows.Forms.MessageBox]::Show("$message")
    }
    else
    {
        Write-Host "$message" -ForegroundColor Yellow
        $x = $host.ui.RawUI.ReadKey("NoEcho,IncludeKeyDown")
    }
}

If you want to create and submit your form from Javascript as is in your question and you want to create popup window with custom features I propose this solution (I put comments above the lines i added):

var form = document.createElement("form");
form.setAttribute("method", "post");
form.setAttribute("action", "test.jsp");

// setting form target to a window named 'formresult'
form.setAttribute("target", "formresult");

var hiddenField = document.createElement("input");              
hiddenField.setAttribute("name", "id");
hiddenField.setAttribute("value", "bob");
form.appendChild(hiddenField);
document.body.appendChild(form);

// creating the 'formresult' window with custom features prior to submitting the form
window.open('test.html', 'formresult', 'scrollbars=no,menubar=no,height=600,width=800,resizable=yes,toolbar=no,status=no');

form.submit();

I found the easiest way using bootstrap 4.

<div class="input-group mb-3">
    <div class="input-group-prepend">
    <span class="input-group-text"><i class="fa fa-user"></i></span></div>
    <input type="text"/>
</div>

you mean something like this ?

from numpy  import array
a = array( your_list )

I have a data set with Time as the x-axis, and Intensity as y-axis. I'd need to first delete all the default axes except the axes' labels with:

plot(Time,Intensity,axes=F)

Then I rebuild the plot's elements with:

box() # create a wrap around the points plotted
axis(labels=NA,side=1,tck=-0.015,at=c(seq(from=0,to=1000,by=100))) # labels = NA prevents the creation of the numbers and tick marks, tck is how long the tick mark is.
axis(labels=NA,side=2,tck=-0.015)
axis(lwd=0,side=1,line=-0.4,at=c(seq(from=0,to=1000,by=100))) # lwd option sets the tick mark to 0 length because tck already takes care of the mark
axis(lwd=0,line=-0.4,side=2,las=1) # las changes the direction of the number labels to horizontal instead of vertical.

So, at = c(...) specifies the collection of positions to put the tick marks. Here I'd like to put the marks at 0, 100, 200,..., 1000. seq(from =...,to =...,by =...) gives me the choice of limits and the increments.

If You want to call the function while right click event means we can use following

 <html lang="en" oncontextmenu="func(); return false;">
 </html>

<script>
function func(){
alert("Yes");
}
</script>

In my case it was the problem of building the extension, I was pointing at an extension src (with manifest and everything) but without a build.

If you run into this scenario run npm i then npm build

I'd advise to go for Gordon's solution as it is more performant than substr():

<?php 

$string = 'abcdef';
$repetitions = 10000000;

echo "\n\n";
echo "----------------------------------\n";
echo $repetitions . " repetitions...\n";
echo "----------------------------------\n";
echo "\n\n";

$start = microtime(true);
for($i=0; $i<$repetitions; $i++)
    $x = substr($string, -1);

echo "substr() took " . (microtime(true) - $start) . "seconds\n";

$start = microtime(true);
for($i=0; $i<$repetitions; $i++)
    $x = $string[strlen($string)-1];

echo "array access took " . (microtime(true) - $start) . "seconds\n";

die();

outputs something like

 ---------------------------------- 
 10000000 repetitions...
 ----------------------------------

 substr() took 2.0285921096802seconds 
 array access took 1.7474739551544seconds

Probably going overboard a bit but i provided call backs for both the execution code and the results. obviously for thread safety you want to be careful what you access in your execution callback.

The AsyncTask implementation:

public class AsyncDbCall<ExecuteType,ResultType> extends AsyncTask<ExecuteType, Void,  
ResultType>
{
    public interface ExecuteCallback<E, R>
    {
        public R execute(E executeInput);
    }
    public interface PostExecuteCallback<R>
    {
        public void finish(R result);
    }

    private PostExecuteCallback<ResultType> _resultCallback = null;
    private ExecuteCallback<ExecuteType,ResultType> _executeCallback = null;


    AsyncDbCall(ExecuteCallback<ExecuteType,ResultType> executeCallback, PostExecuteCallback<ResultType> postExecuteCallback)
    {
        _resultCallback = postExecuteCallback;
        _executeCallback = executeCallback;
    }

    AsyncDbCall(ExecuteCallback<ExecuteType,ResultType> executeCallback)
    {
        _executeCallback = executeCallback;
    }

    @Override
    protected ResultType doInBackground(final ExecuteType... params)
    {
        return  _executeCallback.execute(params[0]);
    }

    @Override
    protected void onPostExecute(ResultType result)
    {
        if(_resultCallback != null)
            _resultCallback.finish(result);
    }
}

A callback:

 AsyncDbCall.ExecuteCallback<Device, Device> updateDeviceCallback = new 
 AsyncDbCall.ExecuteCallback<Device, Device>()
    {
        @Override
        public Device execute(Device device)
        {
            deviceDao.updateDevice(device);
            return device;
        }
    };

And finally execution of the async task:

 new AsyncDbCall<>(addDeviceCallback, resultCallback).execute(device);

This error happened to me, generally it'll be a problem due to not including the mysql-connector.jar in your eclipse project (or your IDE).

In my case, it was because of a problem on the OS.

I was editing a table in phpmyadmin, and mysql hung, I restarted Ubuntu. I cleaned the project without being successful. This morning, when I've tried the web server, it work perfectly the first time.

At the first reboot, the OS recognized that there was a problem, and after the second one, it was fixed. I hope this will save some time to somebody that "could" have this problem!

The pipe, |, is a special-character in regex (meaning "or") and you'll have to escape it with a \.

Using your current regex:

I've tried this in Notepad++, as you've mentioned, and it appears to work well.

Mongo lets you update nested documents using a . convention. Take a look: Updating nested documents in mongodb. Here's another question from the past about a merge update, like the one you're looking for I believe: MongoDB atomic update via 'merge' document

To summarize, for me following the two instructions above to change any instances where numberOfLines = 0 to 1 or greater, and manually adding preferredMaxLayoutWidth="0" to each instance of a label inside the storyboard source fixed all of my warnings.

I always use this to encode stuff for URLs. This is completely safe because it will encode every single character even if it doesn't have to be encoded.

function urlEncode(text) {
    encoded = '';
    for (let char of text) {
        encoded += '%' + char.charCodeAt(0).toString(16);
    }
    return encoded;
}

Responsive CSS option to center a button vertically and horizontally without being concerned with parent element size (using data attribute hooks for clarity and separation concerns):

This is one solution. If you want to make it more generic, you can use the StringUtils library.

String value = "{first_name = naresh,last_name = kumar,gender = male}";
value = value.substring(1, value.length()-1);           //remove curly brackets
String[] keyValuePairs = value.split(",");              //split the string to creat key-value pairs
Map<String,String> map = new HashMap<>();               

for(String pair : keyValuePairs)                        //iterate over the pairs
{
    String[] entry = pair.split("=");                   //split the pairs to get key and value 
    map.put(entry[0].trim(), entry[1].trim());          //add them to the hashmap and trim whitespaces
}

For example you can switch

 value = value.substring(1, value.length()-1);

to

 value = StringUtils.substringBetween(value, "{", "}");

if you are using StringUtils which is contained in apache.commons.lang package.

In macOS for those who are using the express version 4.x.x and using the DOTENV plugin, need to use like this:

1. After installing the plugin import like the following in the file where you init the application: require('dotenv').config({path: path.resolve(__dirname+'/.env')});

2. In the root directory create a file '.env' and add the varaiable like:

   NODE_ENV=development or NODE_ENV = development

Open the file in Notepad. Click 'Save As...'. In the 'Encoding:' combo box you will see the current file format.

If your array has static storage allocation, it is default initialized to zero. However, if the array has automatic storage allocation, then you can simply initialize all its elements to zero using an array initializer list which contains a zero.

// function scope
// this initializes all elements to 0
int arr[4] = {0};
// equivalent to
int arr[4] = {0, 0, 0, 0};

// file scope
int arr[4];
// equivalent to
int arr[4] = {0};

Please note that there is no standard way to initialize the elements of an array to a value other than zero using an initializer list which contains a single element (the value). You must explicitly initialize all elements of the array using the initializer list.

// initialize all elements to 4
int arr[4] = {4, 4, 4, 4};
// equivalent to
int arr[] = {4, 4, 4, 4};

You can use the @NamedEntityGraph annotation to your entity to create a loadable query that set which collections you want to load on your query.

The main advantage of this choice is that hibernate makes one single query to retrieve the entity and its collections and only when you choose to use this graph, like this:

Entity configuration

@Entity
@NamedEntityGraph(name = "graph.myEntity.addresesAndPersons", 
attributeNodes = {
    @NamedAttributeNode(value = "addreses"),
    @NamedAttributeNode(value = "persons"
})

Usage

public MyEntity findNamedGraph(Object id, String namedGraph) {
        EntityGraph<MyEntity> graph = em.getEntityGraph(namedGraph);

        Map<String, Object> properties = new HashMap<>();
        properties.put("javax.persistence.loadgraph", graph);

        return em.find(MyEntity.class, id, properties);
    }

For windows users: if you want to install Flask-MongoAlchemy then use the following code

pip install Flask-MongoAlchemy --proxy="http://example.com:port"**

You can do it faster without any imports just by using magics:

%env CUDA_DEVICE_ORDER=PCI_BUS_ID
%env CUDA_VISIBLE_DEVICES=0

Notice that all env variable are strings, so no need to use ". You can verify that env-variable is set up by running: %env <name_of_var>. Or check all of them with %env.

The problem is the you are using POST but actually you have to perform PATCH To fix this add

<input name="_method" type="hidden" value="PATCH">

Just after the Form::model line

Going down your list:

• "Unicode" isn't an encoding, although unfortunately, a lot of documentation imprecisely uses it to refer to whichever Unicode encoding that particular system uses by default. On Windows and Java, this often means UTF-16; in many other places, it means UTF-8. Properly, Unicode refers to the abstract character set itself, not to any particular encoding.
• UTF-16: 2 bytes per "code unit". This is the native format of strings in .NET, and generally in Windows and Java. Values outside the Basic Multilingual Plane (BMP) are encoded as surrogate pairs. These used to be relatively rarely used, but now many consumer applications will need to be aware of non-BMP characters in order to support emojis.
• UTF-8: Variable length encoding, 1-4 bytes per code point. ASCII values are encoded as ASCII using 1 byte.
• UTF-7: Usually used for mail encoding. Chances are if you think you need it and you're not doing mail, you're wrong. (That's just my experience of people posting in newsgroups etc - outside mail, it's really not widely used at all.)
• UTF-32: Fixed width encoding using 4 bytes per code point. This isn't very efficient, but makes life easier outside the BMP. I have a .NET Utf32String class as part of my MiscUtil library, should you ever want it. (It's not been very thoroughly tested, mind you.)
• ASCII: Single byte encoding only using the bottom 7 bits. (Unicode code points 0-127.) No accents etc.
• ANSI: There's no one fixed ANSI encoding - there are lots of them. Usually when people say "ANSI" they mean "the default locale/codepage for my system" which is obtained via Encoding.Default, and is often Windows-1252 but can be other locales.

There's more on my Unicode page and tips for debugging Unicode problems.

The other big resource of code is unicode.org which contains more information than you'll ever be able to work your way through - possibly the most useful bit is the code charts.

In my case,

I realized that remote debugging runs and consumes most of the resources. I did not really need to make the app 64 bit so after forcing it to be 32 Bit, remote debugging did not run and the execution was faster.

You will need to pad with "0" if its a single digit & note getMonth returns 0..11 not 1..12

function printDate() {
    var temp = new Date();
    var dateStr = padStr(temp.getFullYear()) +
                  padStr(1 + temp.getMonth()) +
                  padStr(temp.getDate()) +
                  padStr(temp.getHours()) +
                  padStr(temp.getMinutes()) +
                  padStr(temp.getSeconds());
    debug (dateStr );
}

function padStr(i) {
    return (i < 10) ? "0" + i : "" + i;
}

Below is some code from my BasePageObject class for waits:

public void waitForPageLoadAndTitleContains(int timeout, String pageTitle) {
    WebDriverWait wait = new WebDriverWait(driver, timeout, 1000);
    wait.until(ExpectedConditions.titleContains(pageTitle));
}

public void waitForElementPresence(By locator, int seconds) {
    WebDriverWait wait = new WebDriverWait(driver, seconds);
    wait.until(ExpectedConditions.presenceOfElementLocated(locator));
}

public void jsWaitForPageToLoad(int timeOutInSeconds) {
    JavascriptExecutor js = (JavascriptExecutor) driver;
    String jsCommand = "return document.readyState";

    // Validate readyState before doing any waits
    if (js.executeScript(jsCommand).toString().equals("complete")) {
        return;
    }

    for (int i = 0; i < timeOutInSeconds; i++) {
        TimeManager.waitInSeconds(3);
        if (js.executeScript(jsCommand).toString().equals("complete")) {
            break;
        }
    }
}

   /**
     * Looks for a visible OR invisible element via the provided locator for up
     * to maxWaitTime. Returns as soon as the element is found.
     *
     * @param byLocator
     * @param maxWaitTime - In seconds
     * @return
     *
     */
    public WebElement findElementThatIsPresent(final By byLocator, int maxWaitTime) {
        if (driver == null) {
            nullDriverNullPointerExeption();
        }
        FluentWait<WebDriver> wait = new FluentWait<>(driver).withTimeout(maxWaitTime, java.util.concurrent.TimeUnit.SECONDS)
                .pollingEvery(200, java.util.concurrent.TimeUnit.MILLISECONDS);

        try {
            return wait.until((WebDriver webDriver) -> {
                List<WebElement> elems = driver.findElements(byLocator);
                if (elems.size() > 0) {
                    return elems.get(0);
                } else {
                    return null;
                }
            });
        } catch (Exception e) {
            return null;
        }
    }

Supporting methods:

     /**
     * Gets locator.
     *
     * @param fieldName
     * @return
     */
    public By getBy(String fieldName) {
        try {
            return new Annotations(this.getClass().getDeclaredField(fieldName)).buildBy();
        } catch (NoSuchFieldException e) {
            return null;
        }
    }

find . -type f -print0 | xargs -0 <sed/perl/ruby cmd> will process multiple space contained file names at once loading one interpreter per batch. Much faster.

In case anyone are still interested in this subject, I find that the best approach for filtering lists is to create a generic Filter class and use it with some base reflection/generics techniques contained in the Java old school SDK package. Here's what I did:

public class GenericListFilter<T> extends Filter {

    /**
     * Copycat constructor
     * @param list  the original list to be used
     */
    public GenericListFilter (List<T> list, String reflectMethodName, ArrayAdapter<T> adapter) {
        super ();

        mInternalList = new ArrayList<>(list);
        mAdapterUsed  = adapter;

        try {
            ParameterizedType stringListType = (ParameterizedType)
                    getClass().getField("mInternalList").getGenericType();
            mCompairMethod =
                    stringListType.getActualTypeArguments()[0].getClass().getMethod(reflectMethodName);
        }
        catch (Exception ex) {
            Log.w("GenericListFilter", ex.getMessage(), ex);

            try {
                if (mInternalList.size() > 0) {
                    T type = mInternalList.get(0);
                    mCompairMethod = type.getClass().getMethod(reflectMethodName);
                }
            }
            catch (Exception e) {
                Log.e("GenericListFilter", e.getMessage(), e);
            }

        }
    }

    /**
     * Let's filter the data with the given constraint
     * @param constraint
     * @return
     */
    @Override protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults results = new FilterResults();
        List<T> filteredContents = new ArrayList<>();

        if ( constraint.length() > 0 ) {
            try {
                for (T obj : mInternalList) {
                    String result = (String) mCompairMethod.invoke(obj);
                    if (result.toLowerCase().startsWith(constraint.toString().toLowerCase())) {
                        filteredContents.add(obj);
                    }
                }
            }
            catch (Exception ex) {
                Log.e("GenericListFilter", ex.getMessage(), ex);
            }
        }
        else {
            filteredContents.addAll(mInternalList);
        }

        results.values = filteredContents;
        results.count  = filteredContents.size();
        return results;
    }

    /**
     * Publish the filtering adapter list
     * @param constraint
     * @param results
     */
    @Override protected void publishResults(CharSequence constraint, FilterResults results) {
        mAdapterUsed.clear();
        mAdapterUsed.addAll((List<T>) results.values);

        if ( results.count == 0 ) {
            mAdapterUsed.notifyDataSetInvalidated();
        }
        else {
            mAdapterUsed.notifyDataSetChanged();
        }
    }

    // class properties
    private ArrayAdapter<T> mAdapterUsed;
    private List<T> mInternalList;
    private Method  mCompairMethod;
}

And afterwards, the only thing you need to do is to create the filter as a member class (possibly within the View's "onCreate") passing your adapter reference, your list, and the method to be called for filtering:

this.mFilter = new GenericFilter<MyObjectBean> (list, "getName", adapter);

The only thing missing now, is to override the "getFilter" method in the adapter class:

@Override public Filter getFilter () {
     return MyViewClass.this.mFilter;
}

All done! You should successfully filter your list - Of course, you should also implement your filter algorithm the best way that describes your need, the code bellow is just an example.. Hope it helped, take care.

In case you have a repository with few local checkedout branches /refs/heads/* and few remote branch branches remotes/origin/* AND if you want to convert this into a BARE repository with all branches in /refs/heads/*

you can do the following to save the history.

1. create a bare repository
2. cd into the local repository which has local checkedout branches and remote branches
3. git push /path/to/bare/repo +refs/remotes/origin/:refs/heads/

While there are IPv6 equivalents for the IPv4 address range, you can't convert all IPv6 addresses to IPv4 - there are more IPv6 addresses than there are IPv4 addresses.

The only sane way around this issue is to update your application to be able to understand and store IPv6 addresses.

My solution was to hide the badge, then display it when the user focuses on a form input - thus still adhering to Google's T&Cs.

Note: The reCAPTCHA I was tweaking had been generated by a WordPress plugin, so you may need to wrap the reCAPTCHA with a <div class="inv-recaptcha-holder"> ... </div> yourself.

CSS

.inv-recaptcha-holder {
  visibility: hidden;
  opacity: 0;
  transition: linear opacity 1s;
}

.inv-recaptcha-holder.show {
  visibility: visible;
  opacity: 1;
  transition: linear opacity 1s;
}

jQuery

$(document).ready(function () {
  $('form input, form textarea').on( 'focus', function() {
    $('.inv-recaptcha-holder').addClass( 'show' );
  });
});

Obviously you can change the jQuery selector to target specific forms if necessary.

I would prefer the C++ size constraints over the C versions:

// Ignore to the end of file
cin.ignore(std::numeric_limits<std::streamsize>::max())

// Ignore to the end of line
cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n')

This is how I use it:

runOnUiThread(new Runnable() {
                @Override
                public void run() {
                //Do something on UiThread
            }
        });

My favorite way is called do the sleep to 50. here i variable need to be used inside echo statements.

for i in $(seq 1 50); do
  echo -ne "$i%\033[0K\r"
  sleep 50
done
echo "ended"

Try this:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

I faced the same error and realized that pom.xml had java 1.7 and STS compiler pointed to Java 1.8. Upon changing compiler to 1.7 and rebuild fixed the issue.

PS: This answer is not related to actual question posted but applies to similar error for app Context not loading

Have a look at this way, pretty clever and using css.

CSS

span.reverse {
  unicode-bidi: bidi-override;
  direction: rtl;
}

HTML

<span class="reverse">moc.rehtrebttam@retsambew</span>

The CSS above will then override the reading direction and present the text to the user in the correct order.

Hope it helps

Cheers

Procedure :

1. At first convert the string to char array
2. Then sort the array of character
3. Convert the character array to string
4. Print the string

Code snippet:

    String input = "world";
    char[] arr = input.toCharArray();
    Arrays.sort(arr);
    String sorted = new String(arr);
    System.out.println(sorted);

As the other answers said, the function you need is cv2.rectangle(), but keep in mind that the coordinates for the bounding box vertices need to be integers if they are in a tuple, and they need to be in the order of (left, top) and (right, bottom). Or, equivalently, (xmin, ymin) and (xmax, ymax).

Try this

Get-ChildItem  | % { Write-Host "$($_.FullName)\$buildConfig\$($_.Name).dll" }

In your code,

1. $build-Config is not a valid variable name.
2. $.FullName should be $_.FullName
3. $ should be $_.Name

There is a setting in the IE options that controls whether it should open new links in an existing window or in a new window. I'm not sure if you can control it from the command line but maybe changing this option would be enough for you.

In IE7 it looks like the option is "Reuse windows for launching shortcuts (when tabbed browsing is disabled)".

Thanks Andy W

I found that the mid() did not quite work as I expected and I modified as follows:

def mid(s, offset, amount):
    return s[offset-1:offset+amount-1]

I performed the following test:

print('[1]23', mid('123', 1, 1))
print('1[2]3', mid('123', 2, 1))
print('12[3]', mid('123', 3, 1))
print('[12]3', mid('123', 1, 2))
print('1[23]', mid('123', 2, 2))

Which resulted in:

[1]23 1
1[2]3 2
12[3] 3
[12]3 12
1[23] 23

Which was what I was expecting. The original mid() code produces this:

[1]23 2
1[2]3 3
12[3] 
[12]3 23
1[23] 3

But the left() and right() functions work fine. Thank you.

This is one way of doing this:

add a "group" to your menu:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <group
        android:id="@+id/main_menu_group">
         <item android:id="@+id/done_item"
              android:title="..."
              android:icon="..."
              android:showAsAction="..."/>
    </group>
</menu>

then, add a

Menu menu;

variable to your activity and set it in your override of onCreateOptionsMenu:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    this.menu = menu;
    // inflate your menu here
}

After, add and use this function to your activity when you'd like to show/hide the menu:

public void showOverflowMenu(boolean showMenu){
    if(menu == null)
        return;
    menu.setGroupVisible(R.id.main_menu_group, showMenu);
}

I am not saying this is the best/only way, but it works well for me.

You can specify formal arguments in rake by adding symbol arguments to the task call. For example:

require 'rake'

task :my_task, [:arg1, :arg2] do |t, args|
  puts "Args were: #{args} of class #{args.class}"
  puts "arg1 was: '#{args[:arg1]}' of class #{args[:arg1].class}"
  puts "arg2 was: '#{args[:arg2]}' of class #{args[:arg2].class}"
end

task :invoke_my_task do
  Rake.application.invoke_task("my_task[1, 2]")
end

# or if you prefer this syntax...
task :invoke_my_task_2 do
  Rake::Task[:my_task].invoke(3, 4)
end

# a task with prerequisites passes its 
# arguments to it prerequisites
task :with_prerequisite, [:arg1, :arg2] => :my_task #<- name of prerequisite task

# to specify default values, 
# we take advantage of args being a Rake::TaskArguments object
task :with_defaults, :arg1, :arg2 do |t, args|
  args.with_defaults(:arg1 => :default_1, :arg2 => :default_2)
  puts "Args with defaults were: #{args}"
end

Then, from the command line:

> rake my_task[1,false]
Args were: {:arg1=>"1", :arg2=>"false"} of class Rake::TaskArguments
arg1 was: '1' of class String
arg2 was: 'false' of class String

> rake "my_task[1, 2]"
Args were: {:arg1=>"1", :arg2=>"2"}

> rake invoke_my_task
Args were: {:arg1=>"1", :arg2=>"2"}

> rake invoke_my_task_2
Args were: {:arg1=>3, :arg2=>4}

> rake with_prerequisite[5,6]
Args were: {:arg1=>"5", :arg2=>"6"}

> rake with_defaults
Args with defaults were: {:arg1=>:default_1, :arg2=>:default_2}

> rake with_defaults['x','y']
Args with defaults were: {:arg1=>"x", :arg2=>"y"}

As demonstrated in the second example, if you want to use spaces, the quotes around the target name are necessary to keep the shell from splitting up the arguments at the space.

Looking at the code in rake.rb, it appears that rake does not parse task strings to extract arguments for prerequisites, so you can't do task :t1 => "dep[1,2]". The only way to specify different arguments for a prerequisite would be to invoke it explicitly within the dependent task action, as in :invoke_my_task and :invoke_my_task_2.

Note that some shells (like zsh) require you to escape the brackets: rake my_task\['arg1'\]

The following returns you a string of the timestamp and the name of the file with the most recent timestamp:

find $Directory -type f -printf "%TY-%Tm-%Td-%TH-%TM-%TS %p\n" | sed -r 's/([[:digit:]]{2})\.([[:digit:]]{2,})/\1-\2/' |     sort --field-separator='-' -nrk1 -nrk2 -nrk3 -nrk4 -nrk5 -nrk6 -nrk7 | head -n 1

Resulting in an output of the form: <yy-mm-dd-hh-mm-ss.nanosec> <filename>

I am surprised that the connection string works for you, because it is missing a semi-colon. Set is only used with objects, so you would not say Set strNaam.

Set cn = CreateObject("ADODB.Connection")
With cn
 .Provider = "Microsoft.Jet.OLEDB.4.0"
  .ConnectionString = "Data Source=D:\test.xls " & _
  ";Extended Properties=""Excel 8.0;HDR=Yes;"""
.Open
End With
strQuery = "SELECT * FROM [Sheet1$E36:E38]"
Set rs = cn.Execute(strQuery)
Do While Not rs.EOF
  For i = 0 To rs.Fields.Count - 1
    Debug.Print rs.Fields(i).Name, rs.Fields(i).Value
    strNaam = rs.Fields(0).Value
  Next
  rs.MoveNext
Loop
rs.Close

There are other ways, depending on what you want to do, such as GetString (GetString Method Description).

Following is the example code for how to use foreach in golang

package main

import (
    "fmt"
)

func main() {

    arrayOne := [3]string{"Apple", "Mango", "Banana"}

    for index,element := range arrayOne{

        fmt.Println(index)
        fmt.Println(element)        

    }   

}

This is a running example https://play.golang.org/p/LXptmH4X_0

You can use the onsubmit function.

If you return false the form won't get submitted. Read up about it here.

$('#myform').submit(function() {
  // your code here
});

This example is everyday, once around 9am and once around 5pm. (edited per comments).

Single quotes delimit a string constant or a date/time constant.

Double quotes delimit identifiers for e.g. table names or column names. This is generally only necessary when your identifier doesn't fit the rules for simple identifiers.

See also:

• Do different databases use different name quote?

You can make MySQL use double-quotes per the ANSI standard:

SET GLOBAL SQL_MODE=ANSI_QUOTES

You can make Microsoft SQL Server use double-quotes per the ANSI standard:

SET QUOTED_IDENTIFIER ON

Using this,

        String s = "03/24/2013 21:54";
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy HH:mm");
        try
        {
            Date date = simpleDateFormat.parse(s);

            System.out.println("date : "+simpleDateFormat.format(date));
        }
        catch (ParseException ex)
        {
            System.out.println("Exception "+ex);
        }

EDIT: Okay, so you don't want your local time (which isn't Australia) to contribute to the result, but instead the Australian time zone. Your existing code should be absolutely fine then, although Sydney is currently UTC+11, not UTC+10.. Short but complete test app:

import java.util.*;
import java.text.*;

public class Test {
    public static void main(String[] args) throws InterruptedException {
        Date date = new Date(1318386508000L);
        DateFormat format = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
        format.setTimeZone(TimeZone.getTimeZone("Etc/UTC"));
        String formatted = format.format(date);
        System.out.println(formatted);
        format.setTimeZone(TimeZone.getTimeZone("Australia/Sydney"));
        formatted = format.format(date);
        System.out.println(formatted);
    }
}

Output:

12/10/2011 02:28:28
12/10/2011 13:28:28

I would also suggest you start using Joda Time which is simply a much nicer date/time API...

EDIT: Note that if your system doesn't know about the Australia/Sydney time zone, it would show UTC. For example, if I change the code about to use TimeZone.getTimeZone("blah/blah") it will show the UTC value twice. I suggest you print TimeZone.getTimeZone("Australia/Sydney").getDisplayName() and see what it says... and check your code for typos too :)

That should be possible using Socket.IO-client: https://github.com/LearnBoost/socket.io-client

import csv
cols = [' V1', ' I1'] # define your columns here, check the spaces!
data = [[] for col in cols] # this creates a list of **different** lists, not a list of pointers to the same list like you did in [[]]*len(positions) 
with open('data.csv', 'r') as f:
    for rec in csv.DictReader(f):
        for l, col in zip(data, cols):
            l.append(float(rec[col]))
print data

# [[3.0, 3.0], [0.01, 0.01]]

In C++, now int and other data is stored using 2's compliment method. That means the range is:

-2147483648 to 2147483647

or -2^31 to 2^31-1

1 bit is reserved for 0 so positive value is one less than 2^(31)

I wrote the following procedure for concatenation of several array:

  static public byte[] concat(byte[]... bufs) {
    if (bufs.length == 0)
        return null;
    if (bufs.length == 1)
        return bufs[0];
    for (int i = 0; i < bufs.length - 1; i++) {
        byte[] res = Arrays.copyOf(bufs[i], bufs[i].length+bufs[i + 1].length);
        System.arraycopy(bufs[i + 1], 0, res, bufs[i].length, bufs[i + 1].length);
        bufs[i + 1] = res;
    }
    return bufs[bufs.length - 1];
}

It uses Arrays.copyOf

In H2, what works for me is:

I code, starting the server like:

server = Server.createTcpServer().start();

That starts the server on localhost port 9092.

Then, in code, establish a DB connection on the following JDBC URL:

jdbc:h2:tcp://localhost:9092/mem:test;DB_CLOSE_DELAY=-1;MODE=MySQL

While debugging, as a client to inspect the DB I use the one provided by H2, which is good enough, to launch it you just need to launch the following java main separately

org.h2.tools.Console

This will start a web server with an app on 8082, launch a browser on localhost:8082

And then you can enter the previous URL to see the DB

If you are willing to insert non-semantic nodes into your document, you can do this in a CSS-only IE-compatible manner by wrapping your divs in fake A tags.

<style type="text/css">
  .content {
    background: #ccc;
  }

  .fakeLink { /* This is to make the link not look like one */
    cursor: default;
    text-decoration: none;
    color: #000;
  }

  a.fakeLink:hover .content {
    background: #000;
    color: #fff;
  }

</style>
<div id="catestory">

  <a href="#" onclick="return false();" class="fakeLink">
    <div class="content">
      <h2>some title here</h2>
      <p>some content here</p>
    </div>
  </a>

  <a href="#" onclick="return false();" class="fakeLink">
    <div class="content">
      <h2>some title here</h2>
      <p>some content here</p>
    </div>
  </a>

  <a href="#" onclick="return false();" class="fakeLink">
    <div class="content">
      <h2>some title here</h2>
      <p>some content here</p>
    </div>
  </a>

</div>

this worked for me:

JS:

$('#fileinput').trigger('click'); 

HTML:

<div class="hiddenfile">
  <input name="upload" type="file" id="fileinput"/>
</div>

CSS:

.hiddenfile {
 width: 0px;
 height: 0px;
 overflow: hidden;
}

>>>Another one that works Cross-Browser:<<<

The Idea is that you overlay an invisible huge "Browse" button over your custom button. So when the user clicks your custom button, he's actually clicking on the "Browse" button of the native input field.

JS Fiddle: http://jsfiddle.net/5Rh7b/

HTML:

<div id="mybutton">
  <input type="file" id="myfile" name="upload"/>
  Click Me!
</div>

CSS:

div#mybutton {

  /* IMPORTANT STUFF */
  overflow: hidden;
  position: relative;   

  /* SOME STYLING */
  width:  50px;
  height: 28px;
  border: 1px solid green;
  font-weight: bold
  background: red;
}

div#mybutton:hover {
  background: green;
}

input#myfile {
  height: 30px;
  cursor: pointer;
  position: absolute;
  top: 0px;
  right: 0px;
  font-size: 100px;
  z-index: 2;

  opacity: 0.0; /* Standard: FF gt 1.5, Opera, Safari */
  filter: alpha(opacity=0); /* IE lt 8 */
  -ms-filter: "alpha(opacity=0)"; /* IE 8 */
  -khtml-opacity: 0.0; /* Safari 1.x */
  -moz-opacity: 0.0; /* FF lt 1.5, Netscape */
}

JavaScript:

$(document).ready(function() {
    $('#myfile').change(function(evt) {
        alert($(this).val());
    });
});

Just use Request.QueryString.ToString() to get full query string, like this:

string URL = "http://www.example.com/rendernews.php?"+Request.Querystring.ToString();

To anyone who is still interested in this question: If: 1-decodeByteArray returns null 2-Base64.decode throws bad-base64 Exception

Here is the solution: -You should consider the value sent to you from API is Base64 Encoded and should be decoded first in order to cast it to a Bitmap object! -Take a look at your Base64 encoded String, If it starts with

data:image/jpg;base64

The Base64.decode won't be able to decode it, So it has to be removed from your encoded String:

final String encodedString = "data:image/jpg;base64, ....";                        
final String pureBase64Encoded = encodedString.substring(encodedString.indexOf(",")  + 1);

Now the pureBase64Encoded object is ready to be decoded:

final byte[] decodedBytes = Base64.decode(pureBase64Encoded, Base64.DEFAULT);

Now just simply use the line below to turn this into a Bitmap Object! :

Bitmap decodedBitmap = BitmapFactory.decodeByteArray(decodedBytes, 0, decodedBytes.length);

Or if you're using the great library Glide:

Glide.with(CaptchaFragment.this).load(decodedBytes).crossFade().fitCenter().into(mCatpchaImageView);

This should do the job! It wasted one day on this and came up to this solution!

Note: If you are still getting bad-base64 error consider other Base64.decode flags like Base64.URL_SAFE and so on

Inline elements can't be transformed, and pseudo elements are inline by default, so you must apply display: block or display: inline-block to transform them:

#whatever:after {
  content: "\24B6";
  display: inline-block;
  transform: rotate(30deg);
}

<div id="whatever">Some text </div>

<?php
$a=array("1"=>"302","2"=>"302","3"=>"276","4"=>"301","5"=>"302");
print_r(array_values(array_unique($a)));
?>//`output -> Array ( [0] => 302 [1] => 276 [2] => 301 )`

Not a direct answer to the question, but this may help those who are having trouble creating style information using Typescript.

I was getting an error telling me that the following was incorrect:

let iconStyle = {
    position: 'relative',
    maxHeight: '90px',
    top: '25%',
}

The error told me that "types of property 'position' are incompatible". I have no idea why.

I fixed this by adding a strict Typescript declaration, like so:

let iconStyle: CSSProperties = {
    position: 'relative',
    maxHeight: '90px',
    top: '25%',
}

This works.

Use:

SELECT t.phone, 
       t.phone2 
  FROM jewishyellow.users t
 WHERE t.phone LIKE '813%' 
   AND t.phone2 IS NOT NULL

Modified @Surendra Jnawali' code. It fails

if current time is 23:40:00 i.e greater than start time and less than equals to 23:59:59.

Go to File --> Set Path and add the folder containing the functions as Matlab files. (At least for Matlab 2007b on Vista)

Main reason:SOAPMessageContext NoClassDefFoundError So you need import this Class or jar

The following worked for me

const conString = "postgres://YourUserName:YourPassword@YourHostname:5432/YourDatabaseName";

The open SPF wizard from the previous answer is no longer available, neither the one from Microsoft.

Important: Please note that this answer was written in 2009 and it might not be the most cost-effective solution today in 2019. Online alternatives are better today at this than they were back then.

Here are some online services that you can use:

• PDFShift
• Restpack
• PDF Layer
• DocRaptor
• HTMLPDFAPI
• HTML to PDF Rocket

Have a look at PrinceXML.

It's definitely the best HTML/CSS to PDF converter out there, although it's not free (But hey, your programming might not be free either, so if it saves you 10 hours of work, you're home free (since you also need to take into account that the alternative solutions will require you to setup a dedicated server with the right software)

Oh yeah, did I mention that this is the first (and probably only) HTML2PDF solution that does full ACID2 ?

at the top of your makefile I have found it on another question How can I use Bash syntax in Makefile targets?

for big number.

var min_num = 900;

    if(num_random >= min_num){
        console.log(Math.floor(num_random));
       break; 
    } else {
        console.log(':::'+Math.floor(num_random));

It takes input and show output on a command prompt.

If you are doing this for virtualenv, the kernels in inactive environments might not be shown with jupyter kernelspec list, as suggested above. You can delete it from directory:

Excluding the DataSourceAutoConfiguration.class worked for me:

Laravel 5.5

After having installed Laravel for the first time, I faced the renowned "public folder problem" and I came up with this solution that, in my personal opinion, is "cleaner" then the others I found on the Web.

Achievements

• Don't have public word in the URI
• Protect the .env file against curious people

Everything can be done just editing the .htaccess using mod_rewrite and four simple rules.

Steps

1. Move the .htaccess file in public/.htaccess in the main root
2. Edit it as below

I commented everything, so it should be clear (I hope) also to those who have never used mod_rewrite (not that I'm an expert, all the opposite). Also, to understand the rules, it must be clear that, in Laravel, if Bill connects to https://example.com, https://example.com/index.php is loaded. This file just contains the command header("refresh: 5; https://example.com/public/"), which sends the request to https://example.com/public/index.php. This second index.php is responsible to load the controller and other stuff.

# IfModule prevents the server error if the app is moved in an environment which doesn’t support mod_rewrite
<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    # RULES ORIGINALLY IN public/.htaccess ---
    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} (.+)/$
    RewriteRule ^ %1 [L,R=301]

    # Handle Front Controller...
#    RewriteCond %{REQUEST_FILENAME} !-d
#    RewriteCond %{REQUEST_FILENAME} !-f
#    RewriteRule ^ index.php [L]

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    # --- END

    # PERSONAL RULES ---
    # All the requests on port 80 are redirected on HTTPS
    RewriteCond %{SERVER_PORT} ^80$
    RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R,L]

    # When .env file is requested, server redirects to 404
    RewriteRule ^\.env$ - [R=404,L,NC]

    # If the REQUEST_URI is empty (means: http://example.com), it loads /public/index.php
    # N.B.: REQUEST_URI is *never* actually empty, it contains a slash that must be set as match as below
    # .* means: anything can go here at least 0 times (= accepts any sequence of characters, including an empty string)
    RewriteCond %{REQUEST_URI} ^/$
    RewriteRule ^(.*) /public/index.php [L]

    # If the current request is asking for a REQUEST_FILENAME that:
    # a) !== existent directory
    # b) !== existent file
    # => if URI !== css||js||images/whatever => server loads /public/index.php, which is responsible to load the app and the related controller
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule !^(css|js|images|media)/(.*)$ /public/index.php [L,NC]

    # If the current request is asking for a REQUEST_FILENAME that:
    # a) !== existent directory
    # b) !== existent file
    # => if URI == css||js||images[=$1]/whatever[=$2] => server loads the resource at public/$1/$2
    # If R flag is added, the server not only loads the resource at public/$1/$2 but redirects to it
    # e.g.: bamboo.jpg resides in example.com/public/media/bamboo.jpg
    #       Client asks for example.com/media/bamboo.jpg
    #       Without R flag: the URI remains example.com/media/bamboo.jpg and loads the image
    #       With R flag: the server redirects the client to example.com/public/media/bamboo.jpg and loads the image
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(css|js|images|media)/(.*)$ /public/$1/$2 [L,NC]
    # --- END

</IfModule>

The following rule (originally in public/.htaccess) can be deleted. The same rule, in fact, is explicited in a more detailed way in the last two rules.

# Handle Front Controller...
#    RewriteCond %{REQUEST_FILENAME} !-d
#    RewriteCond %{REQUEST_FILENAME} !-f
#    RewriteRule ^ index.php [L]

EDIT: I missed Abhinav Saraswat's solution and his answer should be the accepted one. Just one, simple and clear rule that redirects all the traffic to the public folder without modifying any file.

To create a "drop down menu" you can use OptionMenu in tkinter

Example of a basic OptionMenu:

from Tkinter import *

master = Tk()

variable = StringVar(master)
variable.set("one") # default value

w = OptionMenu(master, variable, "one", "two", "three")
w.pack()

mainloop()

More information (including the script above) can be found here.

Creating an OptionMenu of the months from a list would be as simple as:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

mainloop()

In order to retrieve the value the user has selected you can simply use a .get() on the variable that we assigned to the widget, in the below case this is variable:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

def ok():
    print ("value is:" + variable.get())

button = Button(master, text="OK", command=ok)
button.pack()

mainloop()

I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.

Update: As Roko C.Bulijan pointed out.. you need to use .insertAfter to insert it after the selected div. Also see updated code if you want it appended to the end instead of beginning when cloned multiple times. DEMO

Code:

   var cloneCount = 1;;
   $("button").click(function(){
      $('#id')
          .clone()
          .attr('id', 'id'+ cloneCount++)
          .insertAfter('[id^=id]:last') 
           //            ^-- Use '#id' if you want to insert the cloned 
           //                element in the beginning
          .text('Cloned ' + (cloneCount-1)); //<--For DEMO
   }); 

Try,

$("#id").clone().attr('id', 'id1').after("#id");

If you want a automatic counter, then see below,

   var cloneCount = 1;
   $("button").click(function(){
      $("#id").clone().attr('id', 'id'+ cloneCount++).insertAfter("#id");
   }); 

Install distribute by downloading and running distribute_setup.py. This will make easy_install available, and from there you can install pip with easy_install pip. Then you can run pip install CAGE. Using pip to install things is a lot easier than messing with manually running setup.py, because pip can do things like:

automatically resolve dependencies
show you a list of all installed packages and their versions
install a set of specified packages from a requirements.txt
upgrade and uninstall packages
work with virtualenv

If you're on Windows, the one downside of pip occurs when there are C library dependencies, as pip will want a C toolchain installed so it can compile things. If that is the case, then there are two options. If there are precompiled binaries on PyPI, then just run easy_install package instead; easy_install knows how to use binary packages. You can also check Christoph Gohlke's site for executable installers of many binary packages. These can also be installed by easy_install if you want to use them with a virtualenv (just point it to the path of the .exe) or you can click and run if you don't care about virtualenv.

The main point is that no matter what route you choose to install packages, at no point are you ever moving around files by hand. You need to get out of the mindset of "I extracted this archive, where do I put these .py files?" That's not how it works. You're either running pip, running easy_install, running setup.py, clicking on an installer package, or using your distribution's installer. At no point are you ever doing anything by hand with the files directly.

You can tell whether Apache is using preform or worker by issuing the following command

apache2ctl -l

In the resulting output, look for mentions of prefork.c or worker.c

First, is 40 collisions for 130 words hashed to 0..99 bad? You can't expect perfect hashing if you are not taking steps specifically for it to happen. An ordinary hash function won't have fewer collisions than a random generator most of the time.

A hash function with a good reputation is MurmurHash3.

Finally, regarding the size of the hash table, it really depends what kind of hash table you have in mind, especially, whether buckets are extensible or one-slot. If buckets are extensible, again there is a choice: you choose the average bucket length for the memory/speed constraints that you have.

I needed to print important warning about skipped tests exactly when PyTest muted literally everything.

I didn't want to fail a test to send a signal, so I did a hack as follow:

def test_2_YellAboutBrokenAndMutedTests():
    import atexit
    def report():
        print C_patch.tidy_text("""
In silent mode PyTest breaks low level stream structure I work with, so
I cannot test if my functionality work fine. I skipped corresponding tests.
Run `py.test -s` to make sure everything is tested.""")
    if sys.stdout != sys.__stdout__:
        atexit.register(report)

The atexit module allows me to print stuff after PyTest released the output streams. The output looks as follow:

============================= test session starts ==============================
platform linux2 -- Python 2.7.3, pytest-2.9.2, py-1.4.31, pluggy-0.3.1
rootdir: /media/Storage/henaro/smyth/Alchemist2-git/sources/C_patch, inifile:

test_C_patch.py .....ssss....s.

===================== 10 passed, 5 skipped in 0.15 seconds =====================
In silent mode PyTest breaks low level stream structure I work with, so
I cannot test if my functionality work fine. I skipped corresponding tests.

~/.../sources/C_patch$

Message is printed even when PyTest is in silent mode, and is not printed if you run stuff with py.test -s, so everything is tested nicely already.

if myVar is null then if block not execute other-wise it will execute.

if (myVar != null) {...}

Ravi's comment is essentially the answer. Functions take their own arguments. If you want them to be the same as the command-line arguments, you must pass them in. Otherwise, you're clearly calling a function without arguments.

That said, you could if you like store the command-line arguments in a global array to use within other functions:

my_function() {
    echo "stored arguments:"
    for arg in "${commandline_args[@]}"; do
        echo "    $arg"
    done
}

commandline_args=("$@")

my_function

You have to access the command-line arguments through the commandline_args variable, not $@, $1, $2, etc., but they're available. I'm unaware of any way to assign directly to the argument array, but if someone knows one, please enlighten me!

Also, note the way I've used and quoted $@ - this is how you ensure special characters (whitespace) don't get mucked up.

We can use ls and many other Linux commands in Windows cmd. Just follow these steps.

Steps:

1) Install Git in your computer - https://git-scm.com/downloads.

2) After installing Git, go to the folder in which Git is installed. Mostly it will be in C drive and then Program Files Folder.

3) In Program Files folder, you will find the folder named Git, find the bin folder which is inside usr folder in the Git folder.

In my case, the location for bin folder was - C:\Program Files\Git\usr\bin

4) Add this location (C:\Program Files\Git\usr\bin) in path variable, in system environment variables.

5) You are done. Restart cmd and try to run ls and other Linux commands.

Python 3:

import urllib.request

htmlsource = urllib.request.FancyURLopener({"http":"http://127.0.0.1:8080"}).open(url).read().decode("utf-8")

I had the same problem. I had changes in the remote and it was still showing "Already up to date". Recloning the repository fixed the problem for me.

GO is like the end of a script.

You could have multiple CREATE TABLE statements, separated by GO. It's a way of isolating one part of the script from another, but submitting it all in one block.

BEGIN and END are just like { and } in C/++/#, Java, etc.

They bound a logical block of code. I tend to use BEGIN and END at the start and end of a stored procedure, but it's not strictly necessary there. Where it IS necessary is for loops, and IF statements, etc, where you need more then one step...

IF EXISTS (SELECT * FROM my_table WHERE id = @id)
BEGIN
   INSERT INTO Log SELECT @id, 'deleted'
   DELETE my_table WHERE id = @id
END

$('html,body').animate({
  scrollTop: $('#answer-<%= @answer.id %>').offset().top - 50
}, 700);

In fact, your query is right except for the typo: your filter is excluding all records: you should change the <= for >= and vice versa:

qry = DBSession.query(User).filter(
        and_(User.birthday <= '1988-01-17', User.birthday >= '1985-01-17'))
# or same:
qry = DBSession.query(User).filter(User.birthday <= '1988-01-17').\
        filter(User.birthday >= '1985-01-17')

Also you can use between:

qry = DBSession.query(User).filter(User.birthday.between('1985-01-17', '1988-01-17'))

Do something like this:

app.use(function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
    next();
});

SQL is Structured Query Language

MySQL is a relational database management system. You can submit SQL queries to the MySQL database to store, retrieve, modify or delete data.

Can place code anywhere

<input class="my_<? print 'test' ?>"  />

I too faced the same issue and finally solved it by disabling Instant Run in an android studio.

Settings ? Build, Execution, Deployment ? Instant Run and uncheck Enable Instant Run

Update:

There is no Instant Run option available in latest Android Studio 3.5+. It should be applicable only for older versions.

ClassLoader.class.getResourceAsStream("/path/to/your/xml") and make sure that your compile script is copying the xml file to where in your CLASSPATH.

Embedding a Google Drive directory in an IFRAME

Google Drive folders can be embedded and displayed in list and grid views (in which all you can do is click a file or folder to open it on a new tab). To do so, simply replace FOLDER-ID with your own in:

List view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#list" style="width:100%; height:600px; border:0;"></iframe>

or without specifying a mode, since list mode is the default:

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID" style="width:100%; height:600px; border:0;"></iframe>

Grid view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Obtaining your folder id

The id is the hash (alphanumeric gibberish) after folders/ in the URL of the folder. You can see the URL in the address bar of your browser when you open the Drive folder. For example, in:

https://drive.google.com/drive/folders/0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2 

The Folder ID is 0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2.

Folder with G Suite/Google Apps domain

If your folder is part of a Google Apps domain, you can add the domain to the URL to alleviate the permission problems (detailed further ahead):

<iframe src="https://drive.google.com/a/MY.DOMAIN.COM/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Just replace MY.DOMAIN.COM and FOLDER-ID with your own.

Caveat with folders requiring permission

This technique works best for folders with public access. Folders that are shared only with certain Google accounts can cause trouble when you embed them this way, depending on which Google accounts are active on the user's browser:

1. If the user has not logged in to any Google account, then nothing appears in the frame.
2. If the user is logged onto an account without authorisation to access the folder, the frame will contain the message You need permission, with some buttons to Request access or Switch accounts, but if you click on this last, the frame blanks out.
3. If the user logs into an account without proper permissions, and later adds the authorised account, on loading the embedded Drive Google will resort to the first active account, and the user will see You need permission, unless...
4. If the URL contains a Google Suite domain, and the user is logged into that domain's account, the embedded view will work, even if the user logged to another account first.

The blank frames are because Google forbids embedding its login page in an IFRAME (presumably to prevent account stealing), via the X-Frame-Options header, which if set to SAMEORIGIN will cause any well-behaved browser to refuse to load the page if it's not in the same domain (v.g. drive.google.com). You can see this in the developer console of your browser.

TL;DR

To get a list or grid view of a Drive folder (in which all you can do is click a file or folder to open it on a new tab), use:

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

or alternatively, for a Google Suite/Apps Drive:

<iframe src="https://drive.google.com/a/MY.DOMAIN.COM/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Replace MY.DOMAIN.COM and FOLDER-ID with your own; remove #grid to get a detailed file list.

For private folders, have your users log to the correct account before loading the page with the embedded folder; if the folder is in a Google Apps domain, you can add the domain to the URL. Else, they must log into the authorised account before any other.

(this answer is an edit of Mori's, but it was rejected as it changed his intent, somehow)

Use this...

$('#cat_icon').click(function () {
    $('#categories').toggle("slow");
    //$('#cat_icon').hide();
});
$('.panel_title').click(function () {
    $('#categories').toggle("slow");
    //$('#cat_icon').show();
});

Greetings.

Whilst I'm sure POCO means Plain Old Class Object or Plain Old C Object to 99.9% of people here, POCO is also Animator Pro's (Autodesk) built in scripting language.

A good documentation about WebEngines especially webKit and its developers you can read at: WebKit

Although you ask about numpy arrays, you can get the same behavior for regular Python lists by using operator.itemgetter.

>>> from operator import itemgetter
>>> a = [0,88,26,3,48,85,65,16,97,83,91]
>>> ind_pos = [1, 5, 7]
>>> print itemgetter(*ind_pos)(a)
(88, 85, 16)

an example of a key value pair is:

[key: string]: string

you can put anything as the value, of course

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

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

Float.parseFloat() is the problem as it returns a new float.

Returns a new float initialized to the value represented by the specified String, as performed by the valueOf method of class Float.

You are formatting just for the purpose of display . It doesn't mean the float will be represented by the same format internally .

You can use java.lang.BigDecimal.

I am not sure why are you using parseFloat() twice. If you want to display the float in a certain format then just format it and display it.

Float litersOfPetrol=Float.parseFloat(stringLitersOfPetrol);
DecimalFormat df = new DecimalFormat("0.00");
df.setMaximumFractionDigits(2);
System.out.println("liters of petrol before putting in editor"+df.format(litersOfPetrol));

You could do something like this:

function pad ( num, size ) {
  return ( Math.pow( 10, size ) + ~~num ).toString().substring( 1 );
}

Edit: This was just a basic idea for a function, but to add support for larger numbers (as well as invalid input), this would probably be better:

function pad ( num, size ) {
  if (num.toString().length >= size) return num;
  return ( Math.pow( 10, size ) + Math.floor(num) ).toString().substring( 1 );
}

This does 2 things:

1. If the number is larger than the specified size, it will simply return the number.
2. Using Math.floor(num) in place of ~~num will support larger numbers.

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

In some cases it is tied to how the field is used. In some DB engines the field differences determine how (and if) you search for text in the field. CharFields are typically used for things that are searchable, like if you want to search for "one" in the string "one plus two". Since the strings are shorter they are less time consuming for the engine to search through. TextFields are typically not meant to be searched through (like maybe the body of a blog) but are meant to hold large chunks of text. Now most of this depends on the DB Engine and like in Postgres it does not matter.

Even if it does not matter, if you use ModelForms you get a different type of editing field in the form. The ModelForm will generate an HTML form the size of one line of text for a CharField and multiline for a TextField.

As pointed out in other answers, often what you really want the dominant color as opposed to the average color which tends to be brown. I wrote a script that gets the most common color and posted it on this gist

Might be a very late answer, but this is good and simple.

select * from table_name order by id desc limit 5

This query will return a set of last 5 values(last 5 rows) you 've inserted in your table

I found this answer here and I'm using it like this.

Code from my Library:

$.fn.customContextMenu = function(callBack){
    $(this).each(function(){
        $(this).bind("contextmenu",function(e){
             e.preventDefault();
             callBack();
        });
    }); 
}

Code from my page's script:

$("#newmagazine").customContextMenu(function(){
    alert("some code");
});

You can create a Task with cancellation token, when you app goto background you can cancel this token.

You can do this in PCL https://developer.xamarin.com/guides/xamarin-forms/application-fundamentals/app-lifecycle

var cancelToken = new CancellationTokenSource();
Task.Factory.StartNew(async () => {
    await Task.Delay(10000);
    // call web API
}, cancelToken.Token);

//this stops the Task:
cancelToken.Cancel(false);

Anther solution is user Timer in Xamarin.Forms, stop timer when app goto background https://xamarinhelp.com/xamarin-forms-timer/

Just convert it to timestamp

datetime.datetime.fromtimestamp(ms/1000.0)

There is no "second property" -- when you say var obj = { ... }, the properties inside the braces are unordered. Even a 'for' loop walking through them might return them in different orders on different JavaScript implementations.

It's a new paradigm called "Unobtrusive JavaScript". The current "web standard" says to separate functionality and presentation.

It's not really a "bad practice", it's just that most new standards want you to use event listeners instead of in-lining JavaScript.

Also, this may just be a personal thing, but I think it's much easier to read when you use event listeners, especially if you have more than 1 JavaScript statement you want to run.

I have a simple and generic hack to perform key/value if statement instead of boolean-only in mustache (and in an extremely readable fashion!) :

function buildOptions (object) {
    var validTypes = ['string', 'number', 'boolean'];
    var value;
    var key;
    for (key in object) {
        value = object[key];
        if (object.hasOwnProperty(key) && validTypes.indexOf(typeof value) !== -1) {
            object[key + '=' + value] = true;
        }
    }
    return object;
}

With this hack, an object like this:

var contact = {
  "id": 1364,
  "author_name": "Mr Nobody",
  "notified_type": "friendship",
  "action": "create"
};

Will look like this before transformation:

var contact = {
  "id": 1364,
  "id=1364": true,
  "author_name": "Mr Nobody",
  "author_name=Mr Nobody": true,
  "notified_type": "friendship",
  "notified_type=friendship": true,
  "action": "create",
  "action=create": true
};

And your mustache template will look like this:

{{#notified_type=friendship}}
    friendship…
{{/notified_type=friendship}}

{{#notified_type=invite}}
    invite…
{{/notified_type=invite}}

I know its an old post. but I tried the http://scikit-learn.sourceforge.net/stable/ package. here is my code to find the cosine similarity. The question was how will you calculate the cosine similarity with this package and here is my code for that

from sklearn.feature_extraction.text import CountVectorizer
from sklearn.metrics.pairwise import cosine_similarity
from sklearn.feature_extraction.text import TfidfVectorizer

f = open("/root/Myfolder/scoringDocuments/doc1")
doc1 = str.decode(f.read(), "UTF-8", "ignore")
f = open("/root/Myfolder/scoringDocuments/doc2")
doc2 = str.decode(f.read(), "UTF-8", "ignore")
f = open("/root/Myfolder/scoringDocuments/doc3")
doc3 = str.decode(f.read(), "UTF-8", "ignore")

train_set = ["president of India",doc1, doc2, doc3]

tfidf_vectorizer = TfidfVectorizer()
tfidf_matrix_train = tfidf_vectorizer.fit_transform(train_set)  #finds the tfidf score with normalization
print "cosine scores ==> ",cosine_similarity(tfidf_matrix_train[0:1], tfidf_matrix_train)  #here the first element of tfidf_matrix_train is matched with other three elements

Here suppose the query is the first element of train_set and doc1,doc2 and doc3 are the documents which I want to rank with the help of cosine similarity. then I can use this code.

Also the tutorials provided in the question was very useful. Here are all the parts for it part-I,part-II,part-III

the output will be as follows :

[[ 1.          0.07102631  0.02731343  0.06348799]]

here 1 represents that query is matched with itself and the other three are the scores for matching the query with the respective documents.

My solution is based on the onclick event, where I check the value of the input (make sure that it's not empty) on the exact time the event fires and then wait for 1 millisecond and check the value again; if it's empty then it means that the clear button have been clicked not just the input field.

Here's an example using a Vue function:

HTML

<input
  id="searchBar"
  class="form-input col-span-4"
  type="search"
  placeholder="Search..."
  @click="clearFilter($event)"
/>

JS

clearFilter: function ($event) {
  if (event.target.value !== "") {
    setTimeout(function () {
      if (document.getElementById("searchBar").value === "")
        console.log("Clear button is clicked!");
    }, 1);
  }
  console.log("Search bar is clicked but not the clear button.");
},

Double click on it and you're good to go.

You need to call .validate() before you can add rules this way, like this:

$("#myForm").validate(); //sets up the validator
$("input[id*=Hours]").rules("add", "required");

The .validate() documentation is a good guide, here's the blurb about .rules("add", option):

Adds the specified rules and returns all rules for the first matched element. Requires that the parent form is validated, that is, $("form").validate() is called first.

If you want to change settings in the launcher, change icon size, or grid size just hold down on an empty part of your home screen. Tap the three Dots and there you go.

From https://forums.oneplus.net/threads/how-to-change-icon-and-grid-size-trebuchet-settings.84820/

When configuring the phone for first time I saw something about a grid somewhere, but couldn't find it again. Luckily I found the answer on the link above.

dataset <- matrix(sample(c(NA, 1:5), 25, replace = TRUE), 5);
data <- as.data.frame(dataset)

[4,]    2    3   NA    5    5
[5,]    2    3    2    2    3

data[is.na(data)] <- 0

Extending loading Timeout Limit will not solve the problem which caused the error, it just will avoid the system to show the message but performance will be affected whatsoever.

Actual reason: You may be linking files or images to remote locations, and those resources are taking too long to load. (this is likely the most common error)

Definitive solution: move all the scripts, images and css needed to some local folders and load them locally ...

Performance will be increased and error will be effectively solved.

What is Predicate Delegate?

1) Predicate is a feature that returns true or false.This concept has come in .net 2.0 framework. 2) It is being used with lambda expression (=>). It takes generic type as an argument. 3) It allows a predicate function to be defined and passed as a parameter to another function. 4) It is a special case of a Func, in that it takes only a single parameter and always returns a bool.

In C# namespace:

namespace System
{   
    public delegate bool Predicate<in T>(T obj);
}

It is defined in the System namespace.

Where should we use Predicate Delegate?

We should use Predicate Delegate in the following cases:

1) For searching items in a generic collection. e.g.

var employeeDetails = employees.Where(o=>o.employeeId == 1237).FirstOrDefault();

2) Basic example that shortens the code and returns true or false:

Predicate<int> isValueOne = x => x == 1;

now, Call above predicate:

Console.WriteLine(isValueOne.Invoke(1)); // -- returns true.

3) An anonymous method can also be assigned to a Predicate delegate type as below:

Predicate<string> isUpper = delegate(string s) { return s.Equals(s.ToUpper());};
    bool result = isUpper("Hello Chap!!");

Any best practices about predicates?

Use Func, Lambda Expressions and Delegates instead of Predicates.

This is for Android, testing for IPv4 and IPv6

Note: the commonly used InetAddressUtils is deprecated. Use new InetAddress classes

public static Boolean isIPv4Address(String address) {
    if (address.isEmpty()) {
        return false;
    }
    try {
        Object res = InetAddress.getByName(address);
        return res instanceof Inet4Address || res instanceof Inet6Address;
    } catch (final UnknownHostException exception) {
        return false;
    }
}

On Linux the command is whereis. Alternatively you can issue find / -name git and wait for an eternity. Alternatively try echo $PATH | sed "s/:/ /g" | xargs -L 1 ls | grep git

to set session you can try this:

$request->session()->put('key','value');

also to get session data you can try this:

$request->session()->get('key');

If you want to get all session data:

$request->session()->all();

Maven working terminology having phases and goals.

Phase:Maven phase is a set of action which is associated with 2 or 3 goals

exmaple:- if you run mvn clean

this is the phase will execute the goal mvn clean:clean

Goal:Maven goal bounded with the phase

JavaScript has a Number type which is a 64 bit floating point number*.

If you're looking to convert a string to a number, use

1. either parseInt or parseFloat. If using parseInt, I'd recommend always passing the radix too.
2. use the Unary + operator e.g. +"123456"
3. use the Number constructor e.g. var n = Number("12343")

*there are situations where the number will internally be held as an integer.

For removing one element:

 var elem = document.getElementById("yourid");
 elem.parentElement.removeChild(elem);

For removing all the elements with for example a certain class name:

 var list = document.getElementsByClassName("yourclassname");
 for(var i = list.length - 1; 0 <= i; i--)
 if(list[i] && list[i].parentElement)
 list[i].parentElement.removeChild(list[i]);

And for me the argument about whether an array should be sparse or not depends on the context.

For example, if $a[6][9] is not populated is the equivalent to $a[6][9] being populated with for example with "" or 0.

os.path.exists will also return True if there's a regular file with that name.

os.path.isdir will only return True if that path exists and is a directory, or a symbolic link to a directory.

Also you can try to use

display:inline-block;

if you would like the span element to align horizontally.

Incase you would like to align span elements vertically, just use

 display:block;

What I found was that my SHA-1 that was used to sign the app to be uploaded to the Google Playstore was not correct. I realized that my app was being signed by the Google Play Store with a different token. I followed these steps:

1. Go to Google Play Console
2. Click Release Management
3. Click App Signing
4. Convert App-Signing Certificate SHA-1 to Base64 (this will be different than your current upload certificate)

5. Enter Base64 converted SHA-1 into my Facebook Developer dashboard settings

   I am now able to log into my app when the Facebook is downloaded on and Android device.

If you do not want to use Calendar class at all you can use this

String weekday_name = new SimpleDateFormat("EEEE", Locale.ENGLISH).format(System.currentTimeMillis());

i.e., result is,

"Sunday"

Sure, you could use an enum. Would something like the following work?

enum Alignment {
    LEFT,
    RIGHT
}

private static String drawCellValue(int maxCellLength, String cellValue, Alignment alignment) { }

If you wanted to use a boolean, you could rename the align parameter to something like alignLeft. I agree that this implementation is not as clean, but if you don't anticipate a lot of changes and this is not a public interface, it might be a good choice.

According to RFC 793, the port is a 16 bit unsigned int.

This means the range is 0 - 65535.

However, within that range, ports 0 - 1023 are generally reserved for specific purposes. I say generally because, apart from port 0, there is usually no enforcement of the 0-1023 reservation. TCP/UDP implementations usually don't enforce reservations apart from 0. You can, if you want to, run up a web server's TLS port on port 80, or 25, or 65535 instead of the standard 443. Likewise, even tho it is the standard that SMTP servers listen on port 25, you can run it on 80, 443, or others.

Most implementations reserve 0 for a specific purpose - random port assignment. So in most implementations, saying "listen on port 0" actually means "I don't care what port I use, just give me some random unassigned port to listen on".

So any limitation on using a port in the 0-65535 range, including 0, ephemeral reservation range etc, is implementation (i.e. OS/driver) specific, however all, including 0, are valid ports in the RFC 793.

Yes, you can by using DBlink (postgresql only) and DBI-Link (allows foreign cross database queriers) and TDS_LInk which allows queries to be run against MS SQL server.

I have used DB-Link and TDS-link before with great success.
