In my case, my problem was environmental. Meaning, I did something wrong in my bash session. After attempting nearly everything in this thread, I opened a new bash session and everything was back to normal.

The only real difference is that a synchronized block can choose which object it synchronizes on. A synchronized method can only use 'this' (or the corresponding Class instance for a synchronized class method). For example, these are semantically equivalent:

synchronized void foo() {
  ...
}

void foo() {
    synchronized (this) {
      ...
    }
}

The latter is more flexible since it can compete for the associated lock of any object, often a member variable. It's also more granular because you could have concurrent code executing before and after the block but still within the method. Of course, you could just as easily use a synchronized method by refactoring the concurrent code into separate non-synchronized methods. Use whichever makes the code more comprehensible.

This might not be the exact thing you are looking for, but you can create a very similar effect by using rgba in combination with linear-gradient:

  background: linear-gradient(rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%);

This creates a linear-gradient from black with 50% opacity (rgba(0,0,0,.5)) to transparent (rgba(0,0,0,0)) which starts being competently transparent 30% from the top. You can play with those values to create your desired effect. You can have it on a different side by adding a deg-value (linear-gradient(90deg, rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%)) or switching the colors around. If you want really complex shadows like different angles on different sides you could even start layering linear-gradient.

Here is a snippet to see it in action:

.box {_x000D_
  background: linear-gradient(rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%);_x000D_
}_x000D_
_x000D_
.text {_x000D_
  padding: 20px;_x000D_
}

<div class="box">_x000D_
  <div class="text">_x000D_
    Lorem ipsum ...._x000D_
  </div>_x000D_
</div>

In phpMyAdmin, click the table, and then click the Import tab at the top of the page.

Browse and open the csv file. Leave the charset as-is. Uncheck partial import unless you have a HUGE dataset (or slow server). The format should already have selected “CSV” after selecting your file, if not then select it (not using LOAD DATA). If you want to clear the whole table before importing, check “Replace table data with file”. Optionally check “Ignore duplicate rows” if you think you have duplicates in the CSV file. Now the important part, set the next four fields to these values:

Fields terminated by: ,
Fields enclosed by: “
Fields escaped by: \
Lines terminated by: auto

Currently these match the defaults except for “Fields terminated by”, which defaults to a semicolon.

Now click the Go button, and it should run successfully.

jQuery's attr method returns the value of the attribute:

The .attr() method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's .each() or .map() method.

All you need is:

$('html').attr('lang') == 'fr-FR'

However, you might want to do a case-insensitive match:

$('html').attr('lang').toLowerCase() === 'fr-fr'

jQuery's val method returns the value of a form element.

The .val() method is primarily used to get the values of form elements such as input, select and textarea. In the case of <select multiple="multiple"> elements, the .val() method returns an array containing each selected option; if no option is selected, it returns null.

try this:

$('html, body').animate({scrollTop:$('#xxx').position().top}, 'slow');
$('#xxx').focus();

long/int to the byte array looks like exact purpose of struct.pack. For long integers that exceed 4(8) bytes, you can come up with something like the next:

>>> limit = 256*256*256*256 - 1
>>> i = 1234567890987654321
>>> parts = []
>>> while i:
        parts.append(i & limit)
        i >>= 32

>>> struct.pack('>' + 'L'*len(parts), *parts )
'\xb1l\x1c\xb1\x11"\x10\xf4'

>>> struct.unpack('>LL', '\xb1l\x1c\xb1\x11"\x10\xf4')
(2976652465L, 287445236)
>>> (287445236L << 32) + 2976652465L
1234567890987654321L

You can also output your file in xdot format, then render it in a browser using canviz, a JavaScript library.

Canviz on code.google.com:

To see an example, there is a "Canviz Demo" link on the page above as of November 2, 2014.

Non of the solutions worked for me. I had to kill the following process and re ran react-native run-android and it worked.

node ./local-cli/cli.js start

it's simple .. you have to add solid border right, left to col-* and it should be work ..:)

it looks like this : http://i.stack.imgur.com/CF5ZV.png

HTML :

<div class="row">
     <div class="col-sm-3" id="services_block">

     </div>
     <div class="col-sm-3" id="services_block">

     </div>
     <div class="col-sm-3" id="services_block">

     </div>
     <div class="col-sm-3" id="services_block">

     </div>
</div>

CSS :

div#services_block {
   height: 355px;
   background-color: #33363a;
   border-left:3px solid white;
   border-right:3px solid white;
}

This is my attempt using Qt: https://github.com/carlonluca/lqobjectserializer. A JSON like this:

{"menu": {
    "header": "SVG Viewer",
    "items": [
        {"id": "Open"},
        {"id": "OpenNew", "label": "Open New"},
        null,
        {"id": "ZoomIn", "label": "Zoom In"},
        {"id": "ZoomOut", "label": "Zoom Out"},
        {"id": "OriginalView", "label": "Original View"},
        null,
        {"id": "Quality"},
        {"id": "Pause"},
        {"id": "Mute"},
        null,
        {"id": "Find", "label": "Find..."},
        {"id": "FindAgain", "label": "Find Again"},
        {"id": "Copy"},
        {"id": "CopyAgain", "label": "Copy Again"},
        {"id": "CopySVG", "label": "Copy SVG"},
        {"id": "ViewSVG", "label": "View SVG"},
        {"id": "ViewSource", "label": "View Source"},
        {"id": "SaveAs", "label": "Save As"},
        null,
        {"id": "Help"},
        {"id": "About", "label": "About Adobe CVG Viewer..."}
    ]
}}

can be deserialized by declaring classes like these:

L_BEGIN_CLASS(Item)
L_RW_PROP(QString, id, setId, QString())
L_RW_PROP(QString, label, setLabel, QString())
L_END_CLASS

L_BEGIN_CLASS(Menu)
L_RW_PROP(QString, header, setHeader)
L_RW_PROP_ARRAY_WITH_ADDER(Item*, items, setItems)
L_END_CLASS

L_BEGIN_CLASS(MenuRoot)
L_RW_PROP(Menu*, menu, setMenu, nullptr)
L_END_CLASS

and writing writing:

LDeserializer<MenuRoot> deserializer;
QScopedPointer<MenuRoot> g(deserializer.deserialize(jsonString));

You also need to inject mappings for meta objects once:

QHash<QString, QMetaObject> factory {
    { QSL("Item*"), Item::staticMetaObject },
    { QSL("Menu*"), Menu::staticMetaObject }
};

I'm looking for a way to avoid this.

Take care that you also execute your Node script from the ROOT folder.

E.g. I was using a testing script in a subfolder called ./bin/test.js. Calling it like: node ./bin/test.js worked totally fine. Calling it from the subfolder like:

$ pwd
./bin
$ node ./test.js

causes dotenv to not find my ./.env file.

I saw a nested function technique for computing a weighted average on S.O. one time, altering that technique can solve your issue.

def group_weight(overall_size):
    def inner(group):
        return len(group)/float(overall_size)
    inner.__name__ = 'weight'
    return inner

d = {"my_label": pd.Series(['A','B','A','C','D','D','E'])}
df = pd.DataFrame(d)
print df.groupby('my_label').apply(group_weight(len(df)))



my_label
A    0.285714
B    0.142857
C    0.142857
D    0.285714
E    0.142857
dtype: float64

Here is how to do a weighted average within groups

def wavg(val_col_name,wt_col_name):
    def inner(group):
        return (group[val_col_name] * group[wt_col_name]).sum() / group[wt_col_name].sum()
    inner.__name__ = 'wgt_avg'
    return inner



d = {"P": pd.Series(['A','B','A','C','D','D','E'])
     ,"Q": pd.Series([1,2,3,4,5,6,7])
    ,"R": pd.Series([0.1,0.2,0.3,0.4,0.5,0.6,0.7])
     }

df = pd.DataFrame(d)
print df.groupby('P').apply(wavg('Q','R'))

P
A    2.500000
B    2.000000
C    4.000000
D    5.545455
E    7.000000

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

One line answer, F1 -> search for "Color Theme" -> select the color you like

It depends on your project structure. But most straightforward is:

go build -o ./myproject ./...

then run ./myproject.

Suppose your project structure looks like this

- hello
|- main.go

then you just go to the project directory and run

go build -o ./myproject

then run ./myproject on shell.

or

# most easiest; builds and run simultaneously
go run main.go

suppose your main file is nested into a sub-directory like a cmd

- hello
|- cmd
 |- main.go

then you will run

go run cmd/main.go

Just for the sake of completeness, since not much has been said about sorting by column numbers... It can surely be argued that it is often not desirable (because the order of the columns could change, paving the way to errors), but in some specific situations (when for instance you need a quick job done and there is no such risk of columns changing orders), it might be the most sensible thing to do, especially when dealing with large numbers of columns.

In that case, do.call() comes to the rescue:

ind <- do.call(what = "order", args = iris[,c(5,1,2,3)])
iris[ind, ]

##        Sepal.Length Sepal.Width Petal.Length Petal.Width    Species
##    14           4.3         3.0          1.1         0.1     setosa
##    9            4.4         2.9          1.4         0.2     setosa
##    39           4.4         3.0          1.3         0.2     setosa

##    42           4.5         2.3          1.3         0.3     setosa

DIVs inherently lack any useful meaning, other than to divide, of course.

Best course of action would be to add a meaningful class name to them, and style their individual margins in CSS.

<h1>Important Title</h1>
<div class="testimonials">...</div>
<div class="footer">...</div>

h1 {margin-bottom: 0.1em;}
div.testimonials {margin-bottom: 0.2em;}
div.footer {margin-bottom: 0;}

In Python, you can't. Tuples are immutable.

On the containing list, you could replace tuple ('1', '2', '3', '4') with a different ('1', '2', '3', '4', '1234') tuple though.

Answering my own question about 2 or something years later here but...

It uses a protocol extension so you can do it without any extra code for all classes.

/*

Prerequisites
-------------
- In IB set the view's class to the type hook up any IBOutlets
- In IB ensure the file's owner is blank

*/

public protocol CreatedFromNib {
    static func createFromNib() -> Self?
    static func nibName() -> String?
}

extension UIView: CreatedFromNib { }

public extension CreatedFromNib where Self: UIView {

    public static func createFromNib() -> Self? {
        guard let nibName = nibName() else { return nil }
        guard let view = NSBundle.mainBundle().loadNibNamed(nibName, owner: nil, options: nil).last as? Self else { return nil }
        return view
    }

    public static func nibName() -> String? {
        guard let n = NSStringFromClass(Self.self).componentsSeparatedByString(".").last else { return nil }
        return n
    }
}

// Usage:
let myView = MyView().createFromNib()

To find case-insensitive literals string:

Using regex (recommended)

db.collection.find({
    name: {
        $regex: new RegExp('^' + name.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&') + '$', 'i')
    }
});

Using lower-case index (faster)

db.collection.find({
    name_lower: name.toLowerCase()
});

Regular expressions are slower than literal string matching. However, an additional lowercase field will increase your code complexity. When in doubt, use regular expressions. I would suggest to only use an explicitly lower-case field if it can replace your field, that is, you don't care about the case in the first place.

Note that you will need to escape the name prior to regex. If you want user-input wildcards, prefer appending .replace(/%/g, '.*') after escaping so that you can match "a%" to find all names starting with 'a'.

Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.

So, first build a list, then use pickle.dump to send it to a file...

It is called the extended call syntax. From the documentation:

If the syntax *expression appears in the function call, expression must evaluate to a sequence. Elements from this sequence are treated as if they were additional positional arguments; if there are positional arguments x1,..., xN, and expression evaluates to a sequence y1, ..., yM, this is equivalent to a call with M+N positional arguments x1, ..., xN, y1, ..., yM.

and:

If the syntax **expression appears in the function call, expression must evaluate to a mapping, the contents of which are treated as additional keyword arguments. In the case of a keyword appearing in both expression and as an explicit keyword argument, a TypeError exception is raised.

Something like this might work for you:

"UPDATE myTable SET ... ;
 UPDATE myTable SET ... ;
 UPDATE myTable SET ... ;
 UPDATE myTable SET ... ;"

If any of the posX or posY values are the same, then they could be combined into one query

UPDATE myTable SET posX='39' WHERE id IN('2','3','40');

This helped me out after reading @Mr-Faizan's and other answers.

Untick the 'Enable foreign key checks'

in phpMyAdmin and hit the query. I don't know about WorkBench but the other answers might help you out.

I resolved this by deleting the old buggy user 'bill' entries (this is the important part: both from mysql.user and mysql.db), then created the same user as sad before:

FLUSH PRIVILEGES;
CREATE USER bill@localhost IDENTIFIED BY 'passpass';
grant all privileges on *.* to bill@localhost with grant option;
FLUSH PRIVILEGES;

Worked, user is connecting. Now I'll remove some previlegies from it :)

The method len() returns the number of elements in the list.

Syntax:

len(myArray)

Eg:

myArray = [1, 2, 3]
len(myArray)

Output:

3

This is in no way specific to std::unique_ptr, but applies to any class that is movable. It's guaranteed by the language rules since you are returning by value. The compiler tries to elide copies, invokes a move constructor if it can't remove copies, calls a copy constructor if it can't move, and fails to compile if it can't copy.

If you had a function that accepts std::unique_ptr as an argument you wouldn't be able to pass p to it. You would have to explicitly invoke move constructor, but in this case you shouldn't use variable p after the call to bar().

void bar(std::unique_ptr<int> p)
{
    // ...
}

int main()
{
    unique_ptr<int> p = foo();
    bar(p); // error, can't implicitly invoke move constructor on lvalue
    bar(std::move(p)); // OK but don't use p afterwards
    return 0;
}

Right click on the terminal and select clear option (for ubuntu).

For mac just type clear

Been looking into this for a while and not got any satisfactory answers, however...

1) ANSI escape sequences do work in a terminal on Linux

2) if you can tolerate a limited set of colo(u)rs try this:

print("hello", end=''); print("error", end='', file=sys.stderr); print("goodbye")

In idle "hello" and "goodbye" are in blue and "error" is in red.

Not fantastic, but good enough for now, and easy!

public static string QuitEscChars(this string s) 
{
    return s.Replace(((char)27).ToString(), "");
}

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

Basically if you have a destructor (not the default destructor) it means that the class that you defined has some memory allocation. Suppose that the class is used outside by some client code or by you.

    MyClass x(a, b);
    MyClass y(c, d);
    x = y; // This is a shallow copy if assignment operator is not provided

If MyClass has only some primitive typed members a default assignment operator would work but if it has some pointer members and objects that do not have assignment operators the result would be unpredictable. Therefore we can say that if there is something to delete in destructor of a class, we might need a deep copy operator which means we should provide a copy constructor and assignment operator.

My usual approach is

FK_ColumnNameOfForeignKey_TableNameOfReference_ColumnNameOfReference

Or in other terms

FK_ChildColumnName_ParentTableName_ParentColumnName

This way I can name two foreign keys that reference the same table like a history_info table with column actionBy and actionTo from users_info table

It will be like

FK_actionBy_usersInfo_name - For actionBy
FK_actionTo_usersInfo_name - For actionTo

Note that:

I didn't include the child table name because it seems common sense to me, I am in the table of the child so I can easily assume the child's table name. The total character of it is 26 and fits well to the 30 character limit of oracle which was stated by Charles Burns on a comment here

Note for readers: Many of the best practices listed below do not work in Oracle because of its 30 character name limit. A table name or column name may already be close to 30 characters, so a convention combining the two into a single name requires a truncation standard or other tricks. – Charles Burns

For me to make it work again I just deleted the files

ib_logfile0

and

ib_logfile1

.

from :

I had the same problem, here is to solve.

It should be show up if you add meta og:image

The problem is whatsapp would not show image if you type without http:// and end with / For example, it show up image and description if you type http://google.com/ but not with google.com

Hope it helps someone.

You should do:

try:
    value_index = my_list.index(value)
except:
    value_index = -1;

You have missed out the field name id in the second NOT LIKE. Try:

SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'

The AND in the where clause joins 2 full condition expressions such as id NOT LIKE '1%' and can't be used to list multiple values that the id is 'not like'.

.e:hover{
   background-color:#FF0000;
}

myfun(*some_tuple) does exactly what you request. The * operator simply unpacks the tuple (or any iterable) and passes them as the positional arguments to the function. Read more about unpacking arguments.

Try this:

1. Select Window >> Preferences
2. Expand Team >> SVN
3. Under SVN interface set Client to SVNKit (Pure Java) SVNKit....

They all do different things, since matplotlib uses a hierarchical order in which a figure window contains a figure which may consist of many axes. Additionally, there are functions from the pyplot interface and there are methods on the Figure class. I will discuss both cases below.

pyplot interface

pyplot is a module that collects a couple of functions that allow matplotlib to be used in a functional manner. I here assume that pyplot has been imported as import matplotlib.pyplot as plt. In this case, there are three different commands that remove stuff:

plt.cla() clears an axes, i.e. the currently active axes in the current figure. It leaves the other axes untouched.

plt.clf() clears the entire current figure with all its axes, but leaves the window opened, such that it may be reused for other plots.

plt.close() closes a window, which will be the current window, if not specified otherwise.

Which functions suits you best depends thus on your use-case.

The close() function furthermore allows one to specify which window should be closed. The argument can either be a number or name given to a window when it was created using figure(number_or_name) or it can be a figure instance fig obtained, i.e., usingfig = figure(). If no argument is given to close(), the currently active window will be closed. Furthermore, there is the syntax close('all'), which closes all figures.

methods of the Figure class

Additionally, the Figure class provides methods for clearing figures. I'll assume in the following that fig is an instance of a Figure:

fig.clf() clears the entire figure. This call is equivalent to plt.clf() only if fig is the current figure.

fig.clear() is a synonym for fig.clf()

Note that even del fig will not close the associated figure window. As far as I know the only way to close a figure window is using plt.close(fig) as described above.

Invoking any method on any null reference will always result in an exception. Test if the object is null first:

List<Object> test = null;
if (test != null && !test.isEmpty()) {
    // ...
}

Alternatively, write a method to encapsulate this logic:

public static <T> boolean IsNullOrEmpty(Collection<T> list) {
    return list == null || list.isEmpty();
}

Then you can do:

List<Object> test = null;
if (!IsNullOrEmpty(test)) {
    // ...
}

For me I found the solution after a lot of try which is replacing

HttpClient

with

System.Net.Http.HttpClient

import moment to your project

 import moment from react-moment

Then use it like this

return(
<Moment format="YYYY/MM/DD">{post.date}</Moment>
);

Just iterate over each line in the file. Python automatically checks for the End of file and closes the file for you (using the with syntax).

with open('fileName', 'r') as f:
    for line in f:
       if 'str' in line:
           break

In additions, now it is possible to do with class and static

'use strict'

class Foo {
 static talk() {
     console.log('talk')
 };

 speak() {
     console.log('speak')
 };

};

will give

var a = new Foo();
Foo.talk();  // 'talk'
a.talk();    // err 'is not a function'
a.speak();   // 'speak'
Foo.speak(); // err 'is not a function'

As a not yet fully standardized solution (though in alignment with the color syntax in CSS3) you can use e.g fill="rgba(124,240,10,0.5)". Works fine in Firefox, Opera, Chrome.

Here's an example.

  var mapOptions = { zoom:7, mapTypeId: google.maps.MapTypeId.ROADMAP, center: chicago }
  map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
  directionsDisplay.setMap(map);

    width:100px;
    height:100px;

I think something like this:

btn.BackgroundImage = Properties.Resources.*Image_Identifier*;

Where *Image_Identifier* is an identifier of the image in your resources.

If you altered your $PATH variable that could also cause the problem. If you think that might be the issue, check your ~/.bash_profile or ~/.bashrc

Add #include "afxwin.h" in your source file. It will solve your issue.

I believe this does it:

http://bassistance.de/jquery-plugins/jquery-plugin-validation/

It's got built-in patterns for stuff like URLs and e-mail addresses, and I think you can have it use your own as well.

For VB.Net

CType(GridControl1.MainView, GridView).GetFocusedRow()

For C#

((GridView)gridControl1.MainView).GetFocusedRow();

example bind data by linq so use

Dim selRow As CUSTOMER = CType(GridControl1.MainView, GridView).GetFocusedRow()

Yes, you can. Return an Action like this :

return RedirectToAction("View", "Name of Controller");

An example:

return RedirectToAction("Details/" + id.ToString(), "FullTimeEmployees");

This approach will call the GET method

Also you could pass values to action like this:

return RedirectToAction("Details/" + id.ToString(), "FullTimeEmployees", new {id = id.ToString(), viewtype = "extended" });

Instant.now()   // Capture the current moment in UTC. 

Generate a String to represent that value:

Instant.now().toString()  

2016-09-13T23:30:52.123Z

Details

As the correct answer by Jon Skeet stated, a java.util.Date object has no time zone^†. But its toString implementation applies the JVM’s default time zone when generating the String representation of that date-time value. Confusingly to the naïve programmer, a Date seems to have a time zone but does not.

The java.util.Date, j.u.Calendar, and java.text.SimpleDateFormat classes bundled with Java are notoriously troublesome. Avoid them. Instead, use either of these competent date-time libraries:

• java.time.* package in Java 8
• Joda-Time

java.time (Java 8)

Java 8 brings an excellent new java.time.* package to supplant the old java.util.Date/Calendar classes.

Getting current time in UTC/GMT is a simple one-liner…

Instant instant = Instant.now();

That Instant class is the basic building block in java.time, representing a moment on the timeline in UTC with a resolution of nanoseconds.

In Java 8, the current moment is captured with only up to milliseconds resolution. Java 9 brings a fresh implementation of Clock captures the current moment in up to the full nanosecond capability of this class, depending on the ability of your host computer’s clock hardware.

It’s toString method generates a String representation of its value using one specific ISO 8601 format. That format outputs zero, three, six or nine digits digits (milliseconds, microseconds, or nanoseconds) as necessary to represent the fraction-of-second.

If you want more flexible formatting, or other additional features, then apply an offset-from-UTC of zero, for UTC itself (ZoneOffset.UTC constant) to get a OffsetDateTime.

OffsetDateTime now = OffsetDateTime.now( ZoneOffset.UTC );

Dump to console…

System.out.println( "now.toString(): " + now );

When run…

now.toString(): 2014-01-21T23:42:03.522Z

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Joda-Time

UPDATE: The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

Using the Joda-Time 3rd-party open-source free-of-cost library, you can get the current date-time in just one line of code.

Joda-Time inspired the new java.time.* classes in Java 8, but has a different architecture. You may use Joda-Time in older versions of Java. Joda-Time continues to work in Java 8 and continues to be actively maintained (as of 2014). However, the Joda-Time team does advise migration to java.time.

System.out.println( "UTC/GMT date-time in ISO 8601 format: " + new org.joda.time.DateTime( org.joda.time.DateTimeZone.UTC ) );

More detailed example code (Joda-Time 2.3)…

org.joda.time.DateTime now = new org.joda.time.DateTime(); // Default time zone.
org.joda.time.DateTime zulu = now.toDateTime( org.joda.time.DateTimeZone.UTC );

Dump to console…

System.out.println( "Local time in ISO 8601 format: " + now );
System.out.println( "Same moment in UTC (Zulu): " + zulu );

When run…

Local time in ISO 8601 format: 2014-01-21T15:34:29.933-08:00
Same moment in UTC (Zulu): 2014-01-21T23:34:29.933Z

For more example code doing time zone work, see my answer to a similar question.

Time Zone

I recommend you always specify a time zone rather than relying implicitly on the JVM’s current default time zone (which can change at any moment!). Such reliance seems to be a common cause of confusion and bugs in date-time work.

When calling now() pass the desired/expected time zone to be assigned. Use the DateTimeZone class.

DateTimeZone zoneMontréal = DateTimeZone.forID( "America/Montreal" );
DateTime now = DateTime.now( zoneMontréal );

That class holds a constant for UTC time zone.

DateTime now = DateTime.now( DateTimeZone.UTC );

If you truly want to use the JVM’s current default time zone, make an explicit call so your code is self-documenting.

DateTimeZone zoneDefault = DateTimeZone.getDefault();

ISO 8601

Read about ISO 8601 formats. Both java.time and Joda-Time use that standard’s sensible formats as their defaults for both parsing and generating strings.

^† Actually, java.util.Date does have a time zone, buried deep under layers of source code. For most practical purposes, that time zone is ignored. So, as shorthand, we say java.util.Date has no time zone. Furthermore, that buried time zone is not the one used by Date’s toString method; that method uses the JVM’s current default time zone. All the more reason to avoid this confusing class and stick with Joda-Time and java.time.

I had the same problem with nothing was returned from render.

It turns out that my code issue with curly braces {}. I wrote my code like this:

import React from 'react';

const Header = () => {
    <nav class="navbar"></nav>
}

export default Header;

It must be within ():

import React from 'react';

const Header = () => (
    <nav class="navbar"></nav>
);

export default Header;

public class DemoActivity extends Activity {
    /** Called when the activity is first created. */
    ArrayList<String> al = new ArrayList<String>();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);



        // add elements to the array list

        al.add("C");
        al.add("A");
        al.add("E");
        al.add("B");
        al.add("D");
        al.add("F");

        // retrieve elements from array

        String data = al.get(pass the index here);
        System.out.println("Data is "+ data);

This is another way of getting element

        Iterator<String> it = al.iterator();
        while (it.hasNext()) {
            System.out.println("Data is "+ it.next());
        }
    }

It's called URL encoding. More here.

-(NSString *)urlEncodeUsingEncoding:(NSStringEncoding)encoding {
    return (NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,
           (CFStringRef)self,
           NULL,
           (CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ",
           CFStringConvertNSStringEncodingToEncoding(encoding));
}

Note: There is no magic to animating a gif: it is either an animated gif or it is not. If the gif is not visible, very likely the path to the gif is wrong - or, as in your case, the container (div/p/etc) is not large enough to display it. In your code sample, you did not specify height or width and that appeared to be problem.

If the gif is displayed but not animating, see reference links at very bottom of this answer.

Displaying the gif + overlay, however, is easier than you might think.

All you need are two absolute-position DIVs: an overlay div, and a div that contains your loading gif. Both have higher z-index than your page content, and the image has a higher z-index than the overlay - so they will display above the page when visible.

So, when the button is pressed, just unhide those two divs. That's it!

Once upon a midnight dreary, while I pondered weak and weary, over many a quaint and curious routine of forgotten code... While I nodded, nearly napping, suddenly there came a tapping... as of someone gently rapping - rapping at my office door. 'Tis the team leader, I muttered, tapping at my office door - only this and nothing more. Ah, distinctly I remember it was in the bleak December and each separate React print-out lay there crumpled on the floor. Eagerly I wished the morrow; vainly I had sought to borrow from Stack-O surcease from sorrow - sorrow for my routine's core. For the brilliant but unworking code my angels seem to just ignore.

Can em.flush() cause any harm when using it within a transaction?

Yes, it may hold locks in the database for a longer duration than necessary.

Generally, When using JPA you delegates the transaction management to the container (a.k.a CMT - using @Transactional annotation on business methods) which means that a transaction is automatically started when entering the method and commited / rolled back at the end. If you let the EntityManager handle the database synchronization, sql statements execution will be only triggered just before the commit, leading to short lived locks in database. Otherwise your manually flushed write operations may retain locks between the manual flush and the automatic commit which can be long according to remaining method execution time.

Notes that some operation automatically triggers a flush : executing a native query against the same session (EM state must be flushed to be reachable by the SQL query), inserting entities using native generated id (generated by the database, so the insert statement must be triggered thus the EM is able to retrieve the generated id and properly manage relationships)

Hope it helps.That solves my problem,.

To expand/correct on the first answer above, it's not translation that String.format would help with, actually.
What String.format will help with is when you're printing a date/time (or a numeric format, etc), where there are localization(l10n) differences (ie, some countries will print 04Feb2009 and others will print Feb042009).
With translation, you're just talking about moving any externalizable strings (like error messages and what-not) into a property bundle so that you can use the right bundle for the right language, using ResourceBundle and MessageFormat.

Looking at all the above, I'd say that performance-wise, String.format vs. plain concatenation comes down to what you prefer. If you prefer looking at calls to .format over concatenation, then by all means, go with that.
After all, code is read a lot more than it's written.

Of course if i and word are in your environment, then it is just

envsubst < template.txt

Here is an improvement to the solution from mogsie on a similar question, my solution does not require you to escale double quotes, mogsie's does, but his is a one liner!

eval "cat <<EOF
$(<template.txt)
EOF
" 2> /dev/null

The power on these two solutions is that you only get a few types of shell expansions that don't occur normally $((...)), `...`, and $(...), though backslash is an escape character here, but you don't have to worry that the parsing has a bug, and it does multiple lines just fine.

site_request = requests.get("https://abhiunix.in")

print(site_response)

You can do it either way.

Personally i wouldnt store the image in the database, Instead put it in a folder not accessable from outside, and use the database for keeping track of its location. keeps database size down and you can just include it by using PHP. There would be no way without PHP to access that image then

  SELECT * FROM DB1.PERSON_DATA WHERE PERSON_ID = v_lookupid;
  SELECT * FROM DB1.PERSON_HIST WHERE PERSON_ID = v_lookupid;

You can do it implicitly.

// Create the map. There is no restriction to the size that the array String can have
HashMap<Integer, String[]> map = new HashMap<Integer, String[]>();

//initialize a key chosing the array of String you want for your values
map.put(1, new String[] { "name1", "name2" });

//edit value of a key
map.get(1)[0] = "othername";

This is very simple and effective. If you want values of diferent classes instead, you can do the following:

HashMap<Integer, Object[]> map = new HashMap<Integer, Object[]>();

Selecting is often unnecessary. Try this

Sub OneCell()
    Sheets("Sheet2").range("B1:B3").value = Sheets("Sheet1").range("A1:A3").value
End Sub

With underscorejs

_.uniq([1, 2, 1, 3, 1, 4]); //=> [1, 2, 3, 4]

I figured I'd leave this here for those upgrading to Turbolinks 5: the easiest way to fix your code is to go from:

var ready;
ready = function() {
  // Your JS here
}
$(document).ready(ready);
$(document).on('page:load', ready)

to:

var ready;
ready = function() {
  // Your JS here
}
$(document).on('turbolinks:load', ready);

A return value of the previously executed process.

10.4 Getting the return value of a program

In bash, the return value of a program is stored in a special variable called $?.

This illustrates how to capture the return value of a program, I assume that the directory dada does not exist. (This was also suggested by mike)

        #!/bin/bash
        cd /dada &> /dev/null
        echo rv: $?
        cd $(pwd) &> /dev/null
        echo rv: $?

See Bash Programming Manual for more details.

In typescript you can do the following to suppress the error:

let subString?: string;

subString > !null; - Note the added exclamation mark before null.

All you need to do is :

arr.join('');

Everybody commenting seems to be coming at this from the wrong angle, it is fine to store JSON code via PHP in a relational DB and it will in fact be faster to load and display complex data like this, however you will have design considerations such as searching, indexing etc.

The best way of doing this is to use hybrid data, for example if you need to search based upon datetime MySQL (performance tuned) is going to be a lot faster than PHP and for something like searching distance of venues MySQL should also be a lot faster (notice searching not accessing). Data you do not need to search on can then be stored in JSON, BLOB or any other format you really deem necessary.

Data you need to access is very easily stored as JSON for example a basic per-case invoice system. They do not benefit very much at all from RDBMS, and could be stored in JSON just by json_encoding($_POST['entires']) if you have the correct HTML form structure.

I am glad you are happy using MongoDB and I hope that it continues to serve you well, but don't think that MySQL is always going to be off your radar, as your app increases in complexity you may well end up needing an RDBMS for some functionality and features (even if it is just for retiring archived data or business reporting)

The following works. I may be mistaken but adding a String value doesn't seem compatible to a DataGridView cell (I hadn't experimented or tried any hacks though).

DataGridViewName.Rows[0].Cells[0].Value = 1;

one = [1, 2, 3]
two = [9, 8, 5, 3, 2, 1]

all(x in two for x in one)

Explanation: Generator creating booleans by looping through list one checking if that item is in list two. all() returns True if every item is truthy, else False.

There is also an advantage that all return False on the first instance of a missing element rather than having to process every item.

I managed to run a video stream from an USB camera using opencv in docker by following these steps:

1. Let docker access the X server

   xhost +local:docker
   

2. Create the X11 Unix socket and the X authentication file

   XSOCK=/tmp/.X11-unix
   XAUTH=/tmp/.docker.xauth
   

3. Add proper permissions

   xauth nlist $DISPLAY | sed -e 's/^..../ffff/' | xauth -f $XAUTH nmerge -
   

4. Set the Qt rendering speed to "native", so it doesn't bypass the X11 rendering engine

   export QT_GRAPHICSSYSTEM=native
   

5. Tell Qt to not use MIT-SHM (shared memory) - that way it should be also safer security-wise

   export QT_X11_NO_MITSHM=1
   

6. Update the docker run command

   docker run -it \
              -e DISPLAY=$DISPLAY \
              -e XAUTHORITY=$XAUTH \
              -v $XSOCK:$XSOCK \
              -v $XAUTH:$XAUTH \
              --runtime=nvidia \
              --device=/dev/video0:/dev/video0 \
              nvcr.io/nvidia/pytorch:19.10-py3
   

Note: When you finish the the project, return the access controls at their default value - xhost -local:docker

In this post Scrollview vertical and horizontal in android they talk about a possible solution, quoting:

Matt Clark has built a custom view based on the Android source, and it seems to work perfectly: http://blog.gorges.us/2010/06/android-two-dimensional-scrollview

Beware that the class in that page has a bug calculating the view's horizonal width. A fix by Manuel Hilty is in the comments:

Solution: Replace the statement on line 808 by the following:

final int childWidthMeasureSpec = MeasureSpec.makeMeasureSpec(lp.leftMargin + lp.rightMargin, MeasureSpec.UNSPECIFIED);

Why to invent the wheel?

There is a very popular NPM package, that let you do things like that easy.

var recursive = require("recursive-readdir");

recursive("some/path", function (err, files) {
  // `files` is an array of file paths
  console.log(files);
});

Lear more:

• https://www.npmjs.com/package/recursive-readdir

object Enum.Parse(System.Type enumType, string value, bool ignoreCase);

So if you had an enum named mood it would look like this:

   enum Mood
   {
      Angry,
      Happy,
      Sad
   } 

   // ...
   Mood m = (Mood) Enum.Parse(typeof(Mood), "Happy", true);
   Console.WriteLine("My mood is: {0}", m.ToString());

if you are trying to check that in spring frame work then isEmpty method in objectUtils class helps,

public static boolean isEmpty(@Nullable Object[] array) {
        return (array == null || array.length == 0);
    }

If you are using Spring 4.1 and Java 8 you can use java.util.Optional which is supported in @RequestParam, @PathVariable, @RequestHeader and @MatrixVariable in Spring MVC -

@RequestMapping(value = {"/json/{type}", "/json" }, method = RequestMethod.GET)
public @ResponseBody TestBean typedTestBean(
    @PathVariable Optional<String> type,
    @RequestParam("track") String track) {      
    if (type.isPresent()) {
        //type.get() will return type value
        //corresponds to path "/json/{type}"
    } else {
        //corresponds to path "/json"
    }       
}

If you want SQL Server to try and figure it out, just use CAST CAST('whatever' AS datetime) However that is a bad idea in general. There are issues with international dates that would come up. So as you've found, to avoid those issues, you want to use the ODBC canonical format of the date. That is format number 120, 20 is the format for just two digit years. I don't think SQL Server has a built-in function that allows you to provide a user given format. You can write your own and might even find one if you search online.

First Solution

You can use keyboardType = 'numeric' for numeric keyboard.

  <View style={styles.container}>
        <Text style={styles.textStyle}>Enter Number</Text>
        <TextInput
          placeholder={'Enter number here'}
          style={styles.paragraph}
          keyboardType="numeric"
          onChangeText={value => this.onTextChanged(value)}
          value={this.state.number}
        />
      </View>

In first case punctuation marks are included ex:- . and -

Second Solution

Use regular expression to remove punctuation marks.

 onTextChanged(value) {
    // code to remove non-numeric characters from text
    this.setState({ number: value.replace(/[- #*;,.<>\{\}\[\]\\\/]/gi, '') });
  }

Here is the official explanation: https://github.com/golang/go/wiki/InterfaceSlice

var dataSlice []int = foo()
var interfaceSlice []interface{} = make([]interface{}, len(dataSlice))
for i, d := range dataSlice {
    interfaceSlice[i] = d
}

As the name suggests, it acts as a middleware in your routing.

Let's say for any single route, you want to call multiple url or perform multiple functions internally before sending the response. you can use this middleware and pass your route and perform all internal operations.

syntax:
app.use( function(req, res, next) {
  // code
 next();
})

next is optional, you can use to pass the result using this parameter to the next function.

You can create multi-line strings by enclosing them in triple quotes. So you can store your HTML in a string and pass that string to write():

html_str = """
<table border=1>
     <tr>
       <th>Number</th>
       <th>Square</th>
     </tr>
     <indent>
     <% for i in range(10): %>
       <tr>
         <td><%= i %></td>
         <td><%= i**2 %></td>
       </tr>
     </indent>
</table>
"""

Html_file= open("filename","w")
Html_file.write(html_str)
Html_file.close()

npm install --save font-awesome

import 'font-awesome/css/font-awesome.min.css';

then

<i className="fa fa-shopping-cart" style={{fontSize:24}}></i>  
        <span className="badge badge-danger" style={{position:"absolute", right:5, top:5}}>number of items in cart</span>

In my case it was the use of the call_command module that posed a problem.
I added set DJANGO_SETTINGS_MODULE=mysite.settings but it didn't work.

I finally found it:

add these lines at the top of the script, and the order matters.

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

import django
django.setup()

from django.core.management import call_command

One more way can be to use com.google.gdata.util.common.html.HtmlToText class like

MyWriter.toConsole(HtmlToText.htmlToPlainText(htmlResponse));

This is not bullet proof code though and when I run it on wikipedia entries I am getting style info also. However I believe for small/simple jobs this would be effective.

None of these solutions exactly worked for me perfectly because I used navbar-inverse class in my footer. But I did get a solution that worked and Javascript-free. Used Chrome to aid in forming media queries. The height of the footer changes as the screen resizes so you have to pay attention to that and adjust accordingly. Your footer content (I set id="footer" to define my content) should use postion=absolute and bottom=0 to keep it at the bottom. Also width:100%. Here is my CSS with media queries. You'll have to adjust min-width and max-width and add or remove some elements:

#footer {
  position: absolute;
  color:  #ffffff;
  width: 100%;
  bottom: 0; 
}
@media only screen and (min-width:1px) and (max-width: 407px)  {
    body {
        margin-bottom: 275px;
    }

    #footer {
        height: 270px; 
    }
}
@media only screen and (min-width:408px) and (max-width: 768px)  {
    body {
        margin-bottom: 245px;
    }

    #footer {
        height: 240px; 
    }
}
@media only screen and (min-width:769px)   {
    body {
        margin-bottom: 125px;
    }

    #footer {
        height: 120px; 
    }
}

For PyCharm 2018.1 on Mac:

Preferences (?+,), then Editor -> Code Style:

For PyCharm 2018.3 on Windows:

File -> Settings (Ctrl+Alt+S), then Editor -> Code Style:

To follow PEP-8 set Hard wrap at to 80.

Negative numbers mean that you count from the right instead of the left. So, list[-1] refers to the last element, list[-2] is the second-last, and so on.

Range("$A$1").Value = "'01/01/13 00:00" will do it.

Note the single quote; this will defeat automatic conversion to a number type. But is that what you really want? An alternative would be to format the cell to take a date-time value. Then drop the single quote from the string.

You can simply add this CSS to your header

<link href='http://netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css' rel='stylesheet' type='text/css'>

next add this code in place where you want to display a glyph symbol.

<div class="fa fa-search"></div> <!-- smaller -->
<div class="fa fa-search fa-2x"></div> <!-- bigger -->

Have fun.

You should check your designer file. Open Form1.Designer.cs and
find this line: windows Form Designer Generated Code.
Expand this and you will see a lot of code. So check Whether this line is there inside datagridview1 controls if not place it.

this.dataGridView1.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView1_CellClick); 

I hope it helps.

2020 Update

As in Laravel >= 5.3, if someone is still curious how to do so in easy way. Its possible by using : updateOrCreate().

For example for asked question you can use something like:

$matchThese = ['shopId'=>$theID,'metadataKey'=>2001];
ShopMeta::updateOrCreate($matchThese,['shopOwner'=>'New One']);

Above code will check the table represented by ShopMeta, which will be most likely shop_metas unless not defined otherwise in model itself

and it will try to find entry with

column shopId = $theID

and

column metadateKey = 2001

and if it finds then it will update column shopOwner of found row to New One.

If it finds more than one matching rows then it will update the very first row that means which has lowest primary id.

If not found at all then it will insert a new row with :

shopId = $theID,metadateKey = 2001 and shopOwner = New One

Notice Check your model for $fillable and make sue that you have every column name defined there which you want to insert or update and rest columns have either default value or its id column auto incremented one.

Otherwise it will throw error when executing above example:

Illuminate\Database\QueryException with message 'SQLSTATE[HY000]: General error: 1364 Field '...' doesn't have a default value (SQL: insert into `...` (`...`,.., `updated_at`, `created_at`) values (...,.., xxxx-xx-xx xx:xx:xx, xxxx-xx-xx xx:xx:xx))'

As there would be some field which will need value while inserting new row and it will not be possible as either its not defined in $fillable or it doesnt have default value.

For more reference please see Laravel Documentation at : https://laravel.com/docs/5.3/eloquent

One example from there is:

// If there's a flight from Oakland to San Diego, set the price to $99.
// If no matching model exists, create one.
$flight = App\Flight::updateOrCreate(
    ['departure' => 'Oakland', 'destination' => 'San Diego'],
    ['price' => 99]
);

which pretty much clears everything.

Query Builder Update

Someone has asked if it is possible using Query Builder in Laravel. Here is reference for Query Builder from Laravel docs.

Query Builder works exactly the same as Eloquent so anything which is true for Eloquent is true for Query Builder as well. So for this specific case, just use the same function with your query builder like so:

$matchThese = array('shopId'=>$theID,'metadataKey'=>2001);
DB::table('shop_metas')::updateOrCreate($matchThese,['shopOwner'=>'New One']);

Of course, don't forget to add DB facade:

use Illuminate\Support\Facades\DB;

OR

use DB;

I hope it helps

For the sake of completeness, first make sure you have the correct import so you can use the addRow function:

import javax.swing.table.*;

Assuming your jTable is already created, you can proceed and create your own add row method which will accept the parameters that you need:

public void yourAddRow(String str1, String str2, String str3){
  DefaultTableModel yourModel = (DefaultTableModel) yourJTable.getModel();
  yourModel.addRow(new Object[]{str1, str2, str3});
}

In my case I was developing a Polymer WebComponent, which is included using <link rel="import"> into the main HTML document. Turns out that the WebComponent HTML file was being cached for some reason, even though I had changed it since the cached version.

To solve it I opened the Developer Console (in Chrome), right clicked on the reload arrow next to the URL bar and selected "Empty cache and hard reload" - problem solved.

Thank you Cassiopeia for code. I change his code to work with local addresses and made little changes to his conditions. I removed following conditions:

1. Change http:/ to file:///
2. Removed all type of white space conditions
3. Changed 10k cell range condition to 100k

Sub HyperAddForLocalLinks()
Dim CellsWithSpaces As String
    'Converts each text hyperlink selected into a working hyperlink
    Application.ScreenUpdating = False
    Dim NotPresent As Integer
    NotPresent = 0

    For Each xCell In Selection
        xCell.Formula = Trim(xCell.Formula)
            If InStr(xCell.Formula, "file:///") <> 0 Then
                Hyperstring = Trim(xCell.Formula)
            Else
                Hyperstring = "file:///" & Trim(xCell.Formula)
            End If

            ActiveSheet.Hyperlinks.Add Anchor:=xCell, Address:=Hyperstring

        i = i + 1
        If i = 100000 Then Exit Sub
Nextxcell:
      Next xCell
    Application.ScreenUpdating = True
End Sub

This is just a suggestion, it might not work and I'm prepared to be called on this.

This will generate false positives, but hopefully not false negatives.

1. Resize both of the images so that they are the same size (I assume that the ratios of widths to lengths are the same in both images).

2. Compress a bitmap of both images with a lossless compression algorithm (e.g. gzip).

3. Find pairs of files that have similar file sizes. For instance, you could just sort every pair of files you have by how similar the file sizes are and retrieve the top X.

As I said, this will definitely generate false positives, but hopefully not false negatives. You can implement this in five minutes, whereas the Porikil et. al. would probably require extensive work.

You can try opening the wsdl in web browser and saving with .wsdl extension. And set the WSDL in SOAP UI project to this .wsdl file. This really works.

Provide the full path of the file openfile.exe and remember not to put forward slash / in the path such as c:/users/username/etc.... instead of that use c:\\Users\\username\etc (for windows)

May be this will help you.

Nothing has worked. The solution for the issue is.

<style>
table td {
    padding: 0;
}
</style>

Much confusion stems from the existence of at least three major libraries named bootstrap-datepicker:

1. A popular fork of eyecon's datepicker by Andrew 'eternicode' Rowls (use this one!):
   • Online demo, plus download link for the latest release version
   • Comprehensive documentation
   • GitHub repo
2. The original version by Stefan 'eyecon' Petre, still available at http://www.eyecon.ro/bootstrap-datepicker/
3. A totally unrelated datepicker widget that 'storborg' sought to have merged into bootstrap. It wasn't merged and no proper release version of the widget was ever created.

If you're starting a new project - or heck, even if you're taking over an old project using the eyecon version - I recommend that you use eternicode's version, not eyecon's. The original eyecon version is outright inferior in terms of both functionality and documentation, and this is unlikely to change - it has not been updated since March 2013.

You can see most of the capabilities of the eternicode datepicker on the demo page which lets you play with the datepicker's configuration and observe the results. For more detail, see the succinct but comprehensive documentation, which you can probably consume in its entirety in under an hour.

In case you're impatient, though, here's a very short step-by-step guide to the simplest and most common use case for the datepicker.

Quick start guide

1. Include the following libraries (minimum versions noted here) on your page:
   • jQuery
   • Bootstrap - both the JS and CSS
   • The latest release version of bootstrap-datepicker - both the JS and CSS

2. Put an input element on your page somewhere, e.g.

   <input id="my-date-input">
   

3. With jQuery, select your input and call the .datepicker() method:

   jQuery('#my-date-input').datepicker();
   

4. Load your page and click on or tab into your input element. A datepicker will appear:

   

Previous answers were good and correct, but in my opinion, an extra names parameter will make it perfect, and it should be the recommended way, especially when the csv has no headers.

Solution

Use usecols and names parameters

df = pd.read_csv(file_path, usecols=[3,6], names=['colA', 'colB'])

Additional reading

or use header=None to explicitly tells people that the csv has no headers (anyway both lines are identical)

df = pd.read_csv(file_path, usecols=[3,6], names=['colA', 'colB'], header=None)

So that you can retrieve your data by

# with `names` parameter
df['colA']
df['colB'] 

instead of

# without `names` parameter
df[0]
df[1]

Explain

Based on read_csv, when names are passed explicitly, then header will be behaving like None instead of 0, so one can skip header=None when names exist.

Windows7 FireFox/Chrome:

    {
       "cmd":["F:\\Program Files\\Mozilla Firefox\\firefox.exe","$file"]
    }

just use your own path of firefox.exe or chrome.exe to replace mine.

Replace firefox.exe or chrome.exe with your own path.

It's simple: declare the widget variables (editText, textView, button etc.) in class but initialize it in onCreate after setContentView.

The problem is when you try to access a widget of a layout first you have to declare the layout. Declaring the layout is setContentView. And when you initialize the widget variable via findViewById you are accessing the id of the widget in the main layout in the setContentView.

I hope you get it!

If you are reading the dataframe from a file (say CSV or Excel) then use :

• df.read_csv(path , na_filter=False)
• df.read_excel(path , na_filter=False)

This will automatically consider the empty fields as empty strings ''

If you already have the dataframe

• df = df.replace(np.nan, '', regex=True)
• df = df.fillna('')

I agree with Chris Pratt. But I think it's better to create the symlink to original Django folder where the admin templates place in:

ln -s /usr/local/lib/python2.7/dist-packages/django/contrib/admin/templates/admin/ templates/django_admin

and as you can see it depends on python version and the folder where the Django installed. So in future or on a production server you might need to change the path.

You have not included Launcher intent filter in activity you want to appear first, so it does not know which activity to start when application launches, for this tell the system by including launcher filter intent in manifest.xml

If there is other content not being shown inside the outer-div (the green box), why not have that content wrapped inside another div, let's call it "content". Have overflow hidden on this new inner-div, but keep overflow visible on the green box.

The only catch is that you will then have to mess around to make sure that the content div doesn't interfere with the positioning of the red box, but it sounds like you should be able to fix that with little headache.

<div id="1" background: #efe; padding: 5px; width: 125px">
    <div id="content" style="overflow: hidden;">
    </div>
    <div id="2" style="position: relative; background: #fee; padding: 2px; width: 100px; height: 100px">
        <div id="3" style="position: absolute; top: 10px; background: #eef; padding: 2px; width: 75px; height: 150px"/>
    </div>
</div>

You can find a PCA function in the matplotlib module:

import numpy as np
from matplotlib.mlab import PCA

data = np.array(np.random.randint(10,size=(10,3)))
results = PCA(data)

results will store the various parameters of the PCA. It is from the mlab part of matplotlib, which is the compatibility layer with the MATLAB syntax

EDIT: on the blog nextgenetics I found a wonderful demonstration of how to perform and display a PCA with the matplotlib mlab module, have fun and check that blog!

You can create something like if condition afterwards, like

if(!contains(array, obj)) add();

matches return true if the whole string matches the given pattern. find tries to find a substring that matches the pattern.

The toString() method of Selenium's By-Class produces something like "By.xpath: //XpathFoo"

So you could take a substring starting at the colon with something like this:

String selector = divA.toString().substring(s.indexOf(":") + 2);

With this, you could find your element inside your other element with this:

WebElement input = driver.findElement( By.xpath( selector + "//input" ) );

Advantage: You have to search only once on the actual SUT, so it could give you a bonus in performance.

Disadvantage: Ugly... if you want to search for the parent element with css selectory and use xpath for it's childs, you have to check for types before you concatenate... In this case, Slanec's solution (using findElement on a WebElement) is much better.

Try this I It's working.

You can check undefined object using below code.

You could use the load()-event in jQuery but it won't always fire if the image is loaded from the browser cache. This plugin https://github.com/peol/jquery.imgloaded/raw/master/ahpi.imgload.js can be used to remedy that problem.

xcode is now available for free from the app store. Just "buy it" (for free) and it will download. To get the command line tools go into preferences/downloads and "install command line compiler tools".

Instead of gcc you are using clang, but it works the same.

The main reason why you see that error is nltk couldn't find punkt package. Due to the size of nltk suite, all available packages are not downloaded by default when one installs it.

You can download punkt package like this.

import nltk
nltk.download('punkt')

from nltk import word_tokenize,sent_tokenize

If you do not pass any argument to the download function, it downloads all packages i.e chunkers, grammars, misc, sentiment, taggers, corpora, help, models, stemmers, tokenizers.

nltk.download()

The above function saves packages to a specific directory. You can find that directory location from comments here. https://github.com/nltk/nltk/blob/67ad86524d42a3a86b1f5983868fd2990b59f1ba/nltk/downloader.py#L1051

From where would you get these values? If they're from the button itself, you could just do

commentbtn.click(function() {
   alert(this.id);
});

If they're a variable in the binding scope, you can access them from without

var id = 1;
commentbtn.click(function() {
   alert(id);
});

If they're a variable in the binding scope, that might change before the click is called, you'll need to create a new closure

for(var i = 0; i < 5; i++) {
   $('#button'+i).click((function(id) {
      return function() {
         alert(id);
      };
   }(i)));
}

Use the quotemeta function:

$text_to_search = "example text with [foo] and more";
$search_string = quotemeta "[foo]";

print "wee" if ($text_to_search =~ /$search_string/);

See LINQ: How to get the latest/last record with a group by clause

var firstItemsInGroup = from b in mainButtons
                 group b by b.category into g
select g.First();

I assume that mainButtons are already sorted correctly.

If you need to specify custom sort order, use OrderBy override with Comparer.

var firstsByCompareInGroups = from p in rows
        group p by p.ID into grp
        select grp.OrderBy(a => a, new CompareRows()).First();

See an example in my post "Select First Row In Group using Custom Comparer"

INSERT INTO prices(group, id, price)
SELECT 7, articleId, 1.50
FROM article where name like 'ABC%';

This works (pandas v'0.19.2'):

df.rename(columns=df.iloc[0])

XDocument xdoc = XDocument.Load(path_to_xml);
var word = xdoc.Elements("word")
               .SingleOrDefault(w => (string)w.Element("category") == "verb");

This query will return whole word XElement. If there is more than one word element with category verb, than you will get an InvalidOperationException. If there is no elements with category verb, result will be null.

The "Python Packaging Authority" has a sampleproject:

It is a sample project that exists as an aid to the Python Packaging User Guide's Tutorial on Packaging and Distributing Projects.

According to the docs of setState() the new state might not get reflected in the callback function findRoutes(). Here is the extract from React docs:

setState() does not immediately mutate this.state but creates a pending state transition. Accessing this.state after calling this method can potentially return the existing value.

There is no guarantee of synchronous operation of calls to setState and calls may be batched for performance gains.

So here is what I propose you should do. You should pass the new states input in the callback function findRoutes().

handleFormSubmit: function(input){
    // Form Input
    this.setState({
        originId: input.originId,
        destinationId: input.destinationId,
        radius: input.radius,
        search: input.search
    });
    this.findRoutes(input);    // Pass the input here
}

The findRoutes() function should be defined like this:

findRoutes: function(me = this.state) {    // This will accept the input if passed otherwise use this.state
    if (!me.originId || !me.destinationId) {
        alert("findRoutes!");
        return;
    }
    var p1 = new Promise(function(resolve, reject) {
        directionsService.route({
            origin: {'placeId': me.originId},
            destination: {'placeId': me.destinationId},
            travelMode: me.travelMode
        }, function(response, status){
            if (status === google.maps.DirectionsStatus.OK) {
                // me.response = response;
                directionsDisplay.setDirections(response);
                resolve(response);
            } else {
                window.alert('Directions config failed due to ' + status);
            }
        });
    });
    return p1
}

From the AVD Manager try the "Cold Boot Now" option in the drop-down. It worked for me!

In my case, I forgot to add MatDialogModule to imports in a child module.

You can access directly the request array with $request['key'] = 'value';

Hopefully it might help someone.

I tried the above pieces of code but I did not do any streaming.

sudo rabbitmqctl list_queues | awk '{print $1}' > queues.txt; for line in $(cat queues.txt); do sudo rabbitmqctl delete_queue "$line"; done.

I generate a file that contains all the queue names and loops through it line by line to the delete them. For the loops, while read ... did not do it for me. It was always stopping at the first queue name.

Also, if you want to delete a single queue, the above solutions will help(python, Java ...) and also do sudo rabbitmqctl delete_queue queue_name. I am using rabbitmqctl instead of rabbitmqadmin.

If you want to find both the min and max at the same time, the loop can be modified as follows:

int min = int.maxValue;
int max = int.minValue;

foreach num in someArray {
  if(num < min)
    min = num;
  if(num > max)
    max = num;
}

This should get achieve O(n) timing.

You might want to use

return_value = os.popen('ls').read()

instead. os.system only returns the error value.

The os.popen is a neater wrapper for subprocess.Popen function as is seen within the python source code.

An iframe is still the best way to download cross-domain visual content. With AJAX you can certainly download the HTML from a web page and stick it in a div (as others have mentioned) however the bigger problem is security. With iframes you'll be able to load the cross domain content but won't be able to manipulate it since the content doesn't actually belong to you. On the other hand with AJAX you can certainly manipulate any content you are able to download but the other domain's server needs to be setup in such a way that will allow you to download it to begin with. A lot of times you won't have access to the other domain's configuration and even if you do, unless you do that kind of configuration all the time, it can be a headache. In which case the iframe can be the MUCH easier alternative.

As others have mentioned you can also use the embed tag and the object tag but that's not necessarily more advanced or newer than the iframe.

HTML5 has gone more in the direction of adopting web APIs to get information from cross domains. Usually web APIs just return data though and not HTML.

An educational example from the stat documentation:

import os, sys
from stat import *

def walktree(top, callback):
    '''recursively descend the directory tree rooted at top,
       calling the callback function for each regular file'''

    for f in os.listdir(top):
        pathname = os.path.join(top, f)
        mode = os.stat(pathname)[ST_MODE]
        if S_ISDIR(mode):
            # It's a directory, recurse into it
            walktree(pathname, callback)
        elif S_ISREG(mode):
            # It's a file, call the callback function
            callback(pathname)
        else:
            # Unknown file type, print a message
            print 'Skipping %s' % pathname

def visitfile(file):
    print 'visiting', file

if __name__ == '__main__':
    walktree(sys.argv[1], visitfile)

Below code will give the output for number of days, by taking out the difference between two dates..

$str = "Jul 02 2013";
$str = strtotime(date("M d Y ")) - (strtotime($str));
echo floor($str/3600/24);

[UPDATED privacy keys list to iOS 13 - see below]

There is a list of all Cocoa Keys that you can specify in your Info.plist file:

https://developer.apple.com/library/content/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html

(Xcode: Target -> Info -> Custom iOS Target Properties)

iOS already required permissions to access microphone, camera, and media library earlier (iOS 6, iOS 7), but since iOS 10 app will crash if you don't provide the description why you are asking for the permission (it can't be empty).

Privacy keys with example description:

Source

Alternatively, you can open Info.plist as source code:

Source

And add privacy keys like this:

<key>NSLocationAlwaysUsageDescription</key>
<string>${PRODUCT_NAME} always location use</string>

List of all privacy keys: [UPDATED to iOS 13]

NFCReaderUsageDescription
NSAppleMusicUsageDescription
NSBluetoothAlwaysUsageDescription
NSBluetoothPeripheralUsageDescription
NSCalendarsUsageDescription
NSCameraUsageDescription
NSContactsUsageDescription
NSFaceIDUsageDescription
NSHealthShareUsageDescription

NSSiriUsageDescription
NSSpeechRecognitionUsageDescription
NSVideoSubscriberAccountUsageDescription

Update 2019:

In the last months, two of my apps were rejected during the review because the camera usage description wasn't specifying what I do with taken photos.

I had to change the description from ${PRODUCT_NAME} need access to the camera to take a photo to ${PRODUCT_NAME} need access to the camera to update your avatar even though the app context was obvious (user tapped on the avatar).

It seems that Apple is now paying even more attention to the privacy usage descriptions, and we should explain in details why we are asking for permission.

I also tried this answer but was not entirely happy with the result. I kept googling around and finally found a Nuget Package that helped me to manage the result I wanted, anno 2021. I would like to share it with the former developers of Stack Overflow.

I used this Nuget Package Gu.WPF.Geometry found via this Github Repository. All credits for develoment should go to Johan Larsson, the owner of this package.

How I used it? I wanted to have the commands as buttons below the zoombox, as shown here in MachineLayoutControl.xaml .

           </effects:Zoombox>
       </Border>
           <StackPanel
               Grid.Column="1"
               Margin="10"

               Orientation="Horizontal">
               <Button
                   Command="effects:ZoomCommands.Increase"
                   CommandParameter="2.0"
                   CommandTarget="{Binding ElementName=ImageBox}"
                   Content="Zoom In"
                   Style="{StaticResource StyleForResizeButtons}" />

               <Button
                   Command="effects:ZoomCommands.Decrease"
                   CommandParameter="2.0"
                   CommandTarget="{Binding ElementName=ImageBox}"
                   Content="Zoom Out"
                   Style="{StaticResource StyleForResizeButtons}" />

               <Button
                   Command="effects:ZoomCommands.Uniform"
                   CommandTarget="{Binding ElementName=ImageBox}"
                   Content="See Full Machine"
                   Style="{StaticResource StyleForResizeButtons}" />

               <Button
                   Command="effects:ZoomCommands.UniformToFill"
                   CommandTarget="{Binding ElementName=ImageBox}"
                   Content="Zoom To Machine Width"
                   Style="{StaticResource StyleForResizeButtons}" />
   
           </StackPanel>

</Grid>
</UserControl>

In the underlying Viewmodel, I had the following relevant code:

public Visibility Zoombox_Visibility { get => movZoombox_Visibility; set { movZoombox_Visibility = value; OnPropertyChanged(nameof(Zoombox_Visibility)); } }
public Canvas Viewing_Canvas { get => mdvViewing_Canvas; private set => mdvViewing_Canvas = value; }

Also, I wanted that immediately on loading, the Uniform to Fill Command was executed, this is something that I managed to do in the code-behind MachineLayoutControl.xaml.cs . You see that I only set the Zoombox to visible if the command is executed, to avoid "flickering" when the usercontrol is loading.

    public partial class MachineLayoutControl : UserControl
    {
        #region Constructors

        public MachineLayoutControl()
        {
            InitializeComponent();
            Loaded += MyWindow_Loaded;
        }

        #endregion Constructors

        #region EventHandlers

        private void MyWindow_Loaded(object sender, RoutedEventArgs e)
        {
            Application.Current.Dispatcher.BeginInvoke(
               DispatcherPriority.ApplicationIdle,
               new Action(() =>
               {
                   ZoomCommands.Uniform.Execute(null, ImageBox);
                   ((MachineLayoutControlViewModel)DataContext).Zoombox_Visibility = Visibility.Visible;
               }));
        }

        #endregion EventHandlers
    }

The other answer didn't work for me. I had to use mongoose.disconnect(); as stated in this answer.

Implementation of a PDF file in your HTML web-page is very easy.

Make sure to change the width and height for your needs. Good luck!

From the documentation of the DBNull class:

Do not confuse the notion of null in an object-oriented programming language with a DBNull object. In an object-oriented programming language, null means the absence of a reference to an object. DBNull represents an uninitialized variant or nonexistent database column.

try this scp -r -P2222 [email protected]:/home2/kwazy/www/utrecht-connected.nl /Desktop

Another easier option if you're going to be pulling files left and right is to just use an SFTP client like WinSCP. Then you're not typing out 100 characters every time you want to pull something, just drag and drop.

Edit: Just noticed /Desktop probably isn't where you're looking to download the file to. Should be something like C:\Users\you\Desktop

Have a look at http://sqlite.org/lang_conflict.html.

You want something like:

insert or replace into Book (ID, Name, TypeID, Level, Seen) values
((select ID from Book where Name = "SearchName"), "SearchName", ...);

Note that any field not in the insert list will be set to NULL if the row already exists in the table. This is why there's a subselect for the ID column: In the replacement case the statement would set it to NULL and then a fresh ID would be allocated.

This approach can also be used if you want to leave particular field values alone if the row in the replacement case but set the field to NULL in the insert case.

For example, assuming you want to leave Seen alone:

insert or replace into Book (ID, Name, TypeID, Level, Seen) values (
   (select ID from Book where Name = "SearchName"),
   "SearchName",
    5,
    6,
    (select Seen from Book where Name = "SearchName"));

In Vim you can do one of the following:

• Comment all lines: :%s/^/#
• Comment lines 10 - 15: :10,15s/^/#
• Comment line 10 to current line: :10,.s/^/#
• Comment line 10 to end: :10,$s/^/#

or using visual block:

1. Select a multiple-line column after entering visual block via Ctrl+v.
2. Press r followed by # to comment out the multiple-line block replacing the selection, or Shift+i#Esc to insert comment characters before the selection.

I got this error when I only updated the jquery library without updating the jqueryui library in parallel. I was using jquery 1.8.3 with jqueryui 1.9.0. However, when I updated jquery 1.8.3 to 1.9.1 I got the above error. When I commented out the offending .close method lines, it then threw an error about not finding .browser in the jquery library which was deprecated in jquery 1.8.3 and removed from jquery 1.9.1. So bascially, the jquery 1.9.1 library was not compatible with the jquery ui 1.9.0 library despite the jquery ui download page saying it works with jquery 1.6+. Essentially, there are unreported bugs when trying to use differing versions of the two. If you use the jquery version that comes bundled with the jqueryui download, I'm sure you'll be fine, but it's when you start using different versions that you off the beaten path and get errors like this. So, in summary, this error is from mis-matched versions (in my case anyway).

You get this error if you have constrained T to being a class

Just a comment on the method of accomplishing this:

You're making your EntryForm permanently tied to the form you're calling it from. I think it's better to not have forms tied to context like that. I'd remove the requery from the Save/Close routine and instead open the EntryForm modally, using the acDialog switch:

  DoCmd.OpenForm "EntryForm", , ,"[ID]=" & Me!SubForm.Form!ID, , acDialog
  Me!SubForm.Form.Requery

That way, EntryForm is not tied down to use in one context. The alternative is to complicate EntryForm with something that is knowledgable of which form opened it and what needs to requeried. I think it's better to keep that kind of thing as close to the context in which it's used, and keep the called form's code as simple as possible.

Perhaps a principle here is that any time you are requerying a form using the Forms collection from another form, it's a good indication something's not right about your architecture -- that should happen seldom, in my opinion.

Here is what I have:

def is_prime(num):
    if num < 2:         return False
    elif num < 4:       return True
    elif not num % 2:   return False
    elif num < 9:       return True
    elif not num % 3:   return False
    else:
        for n in range(5, int(math.sqrt(num) + 1), 6):
            if not num % n:
                return False
            elif not num % (n + 2):
                return False

    return True

It's pretty fast for large numbers, as it only checks against already prime numbers for divisors of a number.

Now if you want to generate a list of primes, you can do:

# primes up to 'max'
def primes_max(max):
    yield 2
    for n in range(3, max, 2):
        if is_prime(n):
            yield n

# the first 'count' primes
def primes_count(count):
    counter = 0
    num = 3

    yield 2

    while counter < count:
        if is_prime(num):
            yield num
            counter += 1
        num += 2

using generators here might be desired for efficiency.

And just for reference, instead of saying:

one = 1
while one == 1:
    # do stuff

you can simply say:

while 1:
    #do stuff

I was also coming across this issue and for me when doing more updates more issues occurred.

What worked for me in the end was more or less to remove angular cli and re install it with these steps:

npm uninstall -g @angular/cli
npm cache clean --force
npm install -g @angular/cli

this helped me out source: how to uninstall angular/cli

Another option is to use mongoose-history plugin.

let mongoose = require('mongoose');
let mongooseHistory = require('mongoose-history');
let Schema = mongoose.Schema;

let MySchema = Post = new Schema({
    title: String,
    status: Boolean
});

MySchema.plugin(mongooseHistory);
// The plugin will automatically create a new collection with the schema name + "_history".
// In this case, collection with name "my_schema_history" will be created.

There is the solution with Kotlin :

given(myObject.myCall()).willAnswer {
    throw IOException("Ooops")
}

Where given comes from

import org.mockito.BDDMockito.given

Groupby A:

In [0]: grp = df.groupby('A')

Within each group, sum over B and broadcast the values using transform. Then sort by B:

In [1]: grp[['B']].transform(sum).sort('B')
Out[1]:
          B
2 -2.829710
5 -2.829710
1  0.253651
4  0.253651
0  0.551377
3  0.551377

Index the original df by passing the index from above. This will re-order the A values by the aggregate sum of the B values:

In [2]: sort1 = df.ix[grp[['B']].transform(sum).sort('B').index]

In [3]: sort1
Out[3]:
     A         B      C
2  baz -0.528172  False
5  baz -2.301539   True
1  bar -0.611756   True
4  bar  0.865408  False
0  foo  1.624345  False
3  foo -1.072969   True

Finally, sort the 'C' values within groups of 'A' using the sort=False option to preserve the A sort order from step 1:

In [4]: f = lambda x: x.sort('C', ascending=False)

In [5]: sort2 = sort1.groupby('A', sort=False).apply(f)

In [6]: sort2
Out[6]:
         A         B      C
A
baz 5  baz -2.301539   True
    2  baz -0.528172  False
bar 1  bar -0.611756   True
    4  bar  0.865408  False
foo 3  foo -1.072969   True
    0  foo  1.624345  False

Clean up the df index by using reset_index with drop=True:

In [7]: sort2.reset_index(0, drop=True)
Out[7]:
     A         B      C
5  baz -2.301539   True
2  baz -0.528172  False
1  bar -0.611756   True
4  bar  0.865408  False
3  foo -1.072969   True
0  foo  1.624345  False

I found another way without setting proxy. I'm currently using an antivirus which has a firewall program. Then, I turn off this firewall and now I can fetch that URL.

If still doesn't work, try to turn off Firewall on your PC, such as Windows Firewall.

It is not possible to use the RTMP protocol in HTML 5, because the RTMP protocol is only used between the server and the flash player. So you can use the other streaming protocols for viewing the streaming videos in HTML 5.

SELECT eb.n_EmpId,
   em.s_EmpName,
   deg.s_DesignationName,
   dm.s_DeptName
FROM tbl_EmployeeMaster em
 INNER JOIN tbl_DesignationMaster deg ON em.n_DesignationId=deg.n_DesignationId
 INNER JOIN tbl_DepartmentMaster dm ON dm.n_DeptId = em.n_DepartmentId
 INNER JOIN tbl_EmployeeBranch eb ON eb.n_BranchId = em.n_BranchId;

Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -sign before value:

ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) + 
  geom_bar(stat = "identity")

which gives:

Used data:

corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
                         variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
                         value = c(7L, 75L, 70L, 5L, 10L, 47L)),
                    class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))

(,*[\d]+,*[\d]*)+

This would match any small or large number as following with or without comma

1
100
1,262
1,56,262
10,78,999
12,34,56,789

or

1
100
1262
156262
1078999
123456789

based on other solutions, you generate accumulative distribution (as integer or float whatever you like), then you can use bisect to make it fast

this is a simple example (I used integers here)

l=[(20, 'foo'), (60, 'banana'), (10, 'monkey'), (10, 'monkey2')]
def get_cdf(l):
    ret=[]
    c=0
    for i in l: c+=i[0]; ret.append((c, i[1]))
    return ret

def get_random_item(cdf):
    return cdf[bisect.bisect_left(cdf, (random.randint(0, cdf[-1][0]),))][1]

cdf=get_cdf(l)
for i in range(100): print get_random_item(cdf),

the get_cdf function would convert it from 20, 60, 10, 10 into 20, 20+60, 20+60+10, 20+60+10+10

now we pick a random number up to 20+60+10+10 using random.randint then we use bisect to get the actual value in a fast way

I know this is a little late, but here's the solution I had to come up with for handling dates when you want to be timezone independent. Essentially it involves converting everything to UTC.

From Javascript to Server:

Send out dates as epoch values with the timezone offset removed.

var d = new Date(2015,0,1) // Jan 1, 2015
// Ajax Request to server ...
$.ajax({
  url: '/target',
  params: { date: d.getTime() - (d.getTimezoneOffset() * 60 * 1000) }
});

The server then recieves 1420070400000 as the date epoch.

On the Server side, convert that epoch value to a datetime object:

DateTime d = new DateTime(1970, 1, 1, 0, 0, 0).AddMilliseconds(epoch);

At this point the date is just the date/time provided by the user as they provided it. Effectively it is UTC.

Going the other way:

When the server pulls data from the database, presumably in UTC, get the difference as an epoch (making sure that both date objects are either local or UTC):

long ms = (long)utcDate.Subtract(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalMilliseconds;

or

long ms = (long)localDate.Subtract(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Local)).TotalMilliseconds;

When javascript receives this value, create a new date object. However, this date object is going to be assumed local time, so you need to offset it by the current timezone:

var epochValue = 1420070400000 // value pulled from server.
var utcDateVal = new Date(epochValue);
var actualDate = new Date(utcDateVal.getTime() + (utcDateVal.getTimezoneOffset() * 60 * 1000))

console.log(utcDateVal); // Wed Dec 31 2014 19:00:00 GMT-0500 (Eastern Standard Time)
console.log(actualDate); // Thu Jan 01 2015 00:00:00 GMT-0500 (Eastern Standard Time)

As far as I know, this should work for any time zone where you need to display dates that are timezone independent.

git diff --name-only master...branch-name

to which we want to compare.

Here is how you do in Eloquent

$users = User::whereIn('id', array(1, 2, 3))->get();

And if you are using Query builder then :

$users = DB::table('users')->whereIn('id', array(1, 2, 3))->get();

If you are sure you're only ever working with images, you can check out the getimagesize() exif_imagetype() PHP function, which attempts to return the image mime-type.

If you don't mind external dependencies, you can also check out the excellent getID3 library which can determine the mime-type of many different file types.

Lastly, you can check out the mime_content_type() function - but it has been deprecated for the Fileinfo PECL extension.

I had the same issue when my server free disk space available was 0

You can use the command (there must be ample space for the mysql files)

REPAIR TABLE `<table name>`;

for repairing individual tables

I have a suggestion but not a solution. If some of your columns have a larger data sets then you should try with following

SELECT *, LEFT(col1, 0) AS col1, LEFT(col2, 0) as col2 FROM table

I can close it with:

adb shell reboot -p

git remove or git rm can be used for this, with the --cached flag. Try:

git help rm

One of my friends is writing a graphics app using NVIDIA CUDA. Application fits in very nicely with OOP paradigm and the problem can be decomposed into modules neatly. However, to use CUDA you need to use C, which doesn't support inheritance. Therefore, you need to be clever.

a) You devise a clever system which will emulate inheritance to a certain extent. It can be done!

i) You can use a hook system, which expects every child C of parent P to have a certain override for function F. You can make children register their overrides, which will be stored and called when required.

ii) You can use struct memory alignment feature to cast children into parents.

This can be neat but it's not easy to come up with future-proof, reliable solution. You will spend lots of time designing the system and there is no guarantee that you won't run into problems half-way through the project. Implementing multiple inheritance is even harder, if not almost impossible.

b) You can use consistent naming policy and use divide and conquer approach to create a program. It won't have any inheritance but because your functions are small, easy-to-understand and consistently formatted you don't need it. The amount of code you need to write goes up, it's very hard to stay focused and not succumb to easy solutions (hacks). However, this ninja way of coding is the C way of coding. Staying in balance between low-level freedom and writing good code. Good way to achieve this is to write prototypes using a functional language. For example, Haskell is extremely good for prototyping algorithms.

I tend towards approach b. I wrote a possible solution using approach a, and I will be honest, it felt very unnatural using that code.

In Java you can get the keys using ListObjects (see AWS documentation)

FileWriter fileWriter;
BufferedWriter bufferedWriter;
// [...]

AmazonS3 s3client = new AmazonS3Client(new ProfileCredentialsProvider());        

ListObjectsRequest listObjectsRequest = new ListObjectsRequest()
.withBucketName(bucketName)
.withPrefix("myprefix");
ObjectListing objectListing;

do {
    objectListing = s3client.listObjects(listObjectsRequest);
    for (S3ObjectSummary objectSummary : 
        objectListing.getObjectSummaries()) {
        // write to file with e.g. a bufferedWriter
        bufferedWriter.write(objectSummary.getKey());
    }
    listObjectsRequest.setMarker(objectListing.getNextMarker());
} while (objectListing.isTruncated());

Use an object (key/value pairs, the nearest JavaScript has to an associative array) for this and not the array object. Other than that, I believe that is the most elegant way

var foo = {};
foo['alfa'] = "first item";
foo['beta'] = "second item";

for (var key in foo) {
        console.log(key);
}

Note: JavaScript doesn't guarantee any particular order for the properties. So you cannot expect the property that was defined first to appear first, it might come last.

EDIT:

In response to your comment, I believe that this article best sums up the cases for why arrays in JavaScript should not be used in this fashion -

• "Associative Arrays" considered Harmful

Pfft! Microseconds! Never solve a problem in microseconds that can be solved in nanoseconds.

Note that the accepted answer:

• iterates over the whole data, regardless of whether a nan is found
• creates a temporary array of size N, which is redundant.

A better solution is to return True immediately when NAN is found:

import numba
import numpy as np

NAN = float("nan")

@numba.njit(nogil=True)
def _any_nans(a):
    for x in a:
        if np.isnan(x): return True
    return False

@numba.jit
def any_nans(a):
    if not a.dtype.kind=='f': return False
    return _any_nans(a.flat)

array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M)  # 573us

array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M)  # 774ns  (!nanoseconds)

and works for n-dimensions:

array1M_nd = array1M.reshape((len(array1M)/2, 2))
assert any_nans(array1M_nd)==True
%timeit any_nans(array1M_nd)  # 774ns

Compare this to the numpy native solution:

def any_nans(a):
    if not a.dtype.kind=='f': return False
    return np.isnan(a).any()

array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M)  # 456us

array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M)  # 470us

%timeit np.isnan(array1M).any()  # 532us

The early-exit method is 3 orders or magnitude speedup (in some cases). Not too shabby for a simple annotation.

Proof of need for OnPropertyChanged("Count") and OnPropertyChanged("Item[]") calls in order to behave as per ObservableCollection. Note that I don't know what the consequences are if you don't bother!

Here is a test method that shows that there are two PropertyChange events for each add in a normal observable collection. One for "Count" and one for "Item[]".

[TestMethod]
public void TestAddSinglesInOldObsevableCollection()
{
  int colChangedEvents = 0;
  int propChangedEvents = 0;
  var collection = new ObservableCollection<object>();
  collection.CollectionChanged += (sender, e) => { colChangedEvents++; };
  (collection as INotifyPropertyChanged).PropertyChanged += (sender, e) => { propChangedEvents++; };
  collection.Add(new object());
  collection.Add(new object());
  collection.Add(new object());
  Assert.AreEqual(3, colChangedEvents);
  Assert.AreEqual(6, propChangedEvents);
}

@Shimmy , swap the standard for your collection and change to an add range and you will get zero PropertyChanges. Note that collection change does work fine, but not doing exactly what ObservableCollection does. So Test for shimmy collection looks like this:

[TestMethod]
public void TestShimmyAddRange()
{
  int colChangedEvents = 0;
  int propChangedEvents = 0;
  var collection = new ShimmyObservableCollection<object>();
  collection.CollectionChanged += (sender, e) => { colChangedEvents++; };
  (collection as INotifyPropertyChanged).PropertyChanged += (sender, e) => { propChangedEvents++; };
  collection.AddRange(new[]{
    new object(), new object(), new object(), new object()}); //4 objects at once
  Assert.AreEqual(1, colChangedEvents);  //great, just one!
  Assert.AreEqual(2, propChangedEvents); //fails, no events :(
}

FYI here is code from InsertItem (also called by Add) from ObservableCollection:

protected override void InsertItem(int index, T item)
{
  base.CheckReentrancy();
  base.InsertItem(index, item);
  base.OnPropertyChanged("Count");
  base.OnPropertyChanged("Item[]");
  base.OnCollectionChanged(NotifyCollectionChangedAction.Add, item, index);
}

I was having the exact same error. After some hours, I noticed that there was an extra comma in my .JSON file, on the very last key-value pair.

//doesn't work
{
    "key":"value",
    "key":"value",
    "key":"value",
}

Then I just took it off (the last ',') and that solved the problem.

//works
{
    "key":"value",
    "key":"value",
    "key":"value"
}

We had the same problem on a CentOS7 machine. Disabling the VERIFYHOST VERIFYPEER did not solve the problem, we did not have the cURL error anymore but the response still was invalid. Doing a wget to the same link as the cURL was doing also resulted in a certificate error.

-> Our solution also was to reboot the VPS, this solved it and we were able to complete the request again.

For us this seemed to be a memory corruption problem. Rebooting the VPS reloaded the libary in the memory again and now it works. So if the above solution from @clover does not work try to reboot your machine.

I wrote a very simple function that uses jQuery to iterate the elements wrapping each keyword with a .highlight class.

function highlight_words(word, element) {
    if(word) {
        var textNodes;
        word = word.replace(/\W/g, '');
        var str = word.split(" ");
        $(str).each(function() {
            var term = this;
            var textNodes = $(element).contents().filter(function() { return this.nodeType === 3 });
            textNodes.each(function() {
              var content = $(this).text();
              var regex = new RegExp(term, "gi");
              content = content.replace(regex, '<span class="highlight">' + term + '</span>');
              $(this).replaceWith(content);
            });
        });
    }
}

If its working when you are using a browser and then passing on your username and password for the first time - then this means that once authentication is done Request header of your browser is set with required authentication values, which is then passed on each time a request is made to hosting server.

So start with inspecting Request Header (this could be done using Web Developers tools), Once you established whats required in header then you could pass this within your HttpWebRequest Header.

Example with Digest Authentication:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security.Cryptography;
using System.Text.RegularExpressions;
using System.Net;
using System.IO;

namespace NUI
{
    public class DigestAuthFixer
    {
        private static string _host;
        private static string _user;
        private static string _password;
        private static string _realm;
        private static string _nonce;
        private static string _qop;
        private static string _cnonce;
        private static DateTime _cnonceDate;
        private static int _nc;

public DigestAuthFixer(string host, string user, string password)
{
    // TODO: Complete member initialization
    _host = host;
    _user = user;
    _password = password;
}

private string CalculateMd5Hash(
    string input)
{
    var inputBytes = Encoding.ASCII.GetBytes(input);
    var hash = MD5.Create().ComputeHash(inputBytes);
    var sb = new StringBuilder();
    foreach (var b in hash)
        sb.Append(b.ToString("x2"));
    return sb.ToString();
}

private string GrabHeaderVar(
    string varName,
    string header)
{
    var regHeader = new Regex(string.Format(@"{0}=""([^""]*)""", varName));
    var matchHeader = regHeader.Match(header);
    if (matchHeader.Success)
        return matchHeader.Groups[1].Value;
    throw new ApplicationException(string.Format("Header {0} not found", varName));
}

private string GetDigestHeader(
    string dir)
{
    _nc = _nc + 1;

    var ha1 = CalculateMd5Hash(string.Format("{0}:{1}:{2}", _user, _realm, _password));
    var ha2 = CalculateMd5Hash(string.Format("{0}:{1}", "GET", dir));
    var digestResponse =
        CalculateMd5Hash(string.Format("{0}:{1}:{2:00000000}:{3}:{4}:{5}", ha1, _nonce, _nc, _cnonce, _qop, ha2));

    return string.Format("Digest username=\"{0}\", realm=\"{1}\", nonce=\"{2}\", uri=\"{3}\", " +
        "algorithm=MD5, response=\"{4}\", qop={5}, nc={6:00000000}, cnonce=\"{7}\"",
        _user, _realm, _nonce, dir, digestResponse, _qop, _nc, _cnonce);
}

public string GrabResponse(
    string dir)
{
    var url = _host + dir;
    var uri = new Uri(url);

    var request = (HttpWebRequest)WebRequest.Create(uri);

    // If we've got a recent Auth header, re-use it!
    if (!string.IsNullOrEmpty(_cnonce) &&
        DateTime.Now.Subtract(_cnonceDate).TotalHours < 1.0)
    {
        request.Headers.Add("Authorization", GetDigestHeader(dir));
    }

    HttpWebResponse response;
    try
    {
        response = (HttpWebResponse)request.GetResponse();
    }
    catch (WebException ex)
    {
        // Try to fix a 401 exception by adding a Authorization header
        if (ex.Response == null || ((HttpWebResponse)ex.Response).StatusCode != HttpStatusCode.Unauthorized)
            throw;

        var wwwAuthenticateHeader = ex.Response.Headers["WWW-Authenticate"];
        _realm = GrabHeaderVar("realm", wwwAuthenticateHeader);
        _nonce = GrabHeaderVar("nonce", wwwAuthenticateHeader);
        _qop = GrabHeaderVar("qop", wwwAuthenticateHeader);

        _nc = 0;
        _cnonce = new Random().Next(123400, 9999999).ToString();
        _cnonceDate = DateTime.Now;

        var request2 = (HttpWebRequest)WebRequest.Create(uri);
        request2.Headers.Add("Authorization", GetDigestHeader(dir));
        response = (HttpWebResponse)request2.GetResponse();
    }
    var reader = new StreamReader(response.GetResponseStream());
    return reader.ReadToEnd();
}

}

Then you could call it:

DigestAuthFixer digest = new DigestAuthFixer(domain, username, password);
string strReturn = digest.GrabResponse(dir);

if Url is: http://xyz.rss.com/folder/rss then domain: http://xyz.rss.com (domain part) dir: /folder/rss (rest of the url)

you could also return it as stream and use XmlDocument Load() method.

The Address property of a cell can get this for you:

MsgBox Cells(1, 1).Address(RowAbsolute:=False, ColumnAbsolute:=False)

returns A1.

The other way around can be done with the Row and Column property of Range:

MsgBox Range("A1").Row & ", " & Range("A1").Column

returns 1,1.

Using a correlated query:

  SELECT t.id,
         t.count,
         (SELECT SUM(x.count)
            FROM TABLE x
           WHERE x.id <= t.id) AS cumulative_sum
    FROM TABLE t
ORDER BY t.id

Using MySQL variables:

  SELECT t.id,
         t.count,
         @running_total := @running_total + t.count AS cumulative_sum
    FROM TABLE t
    JOIN (SELECT @running_total := 0) r
ORDER BY t.id

Note:

• The JOIN (SELECT @running_total := 0) r is a cross join, and allows for variable declaration without requiring a separate SET command.
• The table alias, r, is required by MySQL for any subquery/derived table/inline view

Caveats:

• MySQL specific; not portable to other databases
• The ORDER BY is important; it ensures the order matches the OP and can have larger implications for more complicated variable usage (IE: psuedo ROW_NUMBER/RANK functionality, which MySQL lacks)

This sometimes does not work if Eclipse is on one of those strange default windows paths (e.g. c:/Program files (86)/Eclipse).

In that case, do as above, then move the lombok jar to a cleaner path without spaces and braces (e.g. c:\lombok\lombok.jar) and modify eclipse.ini accordingly.
