I guess the answer you need is referenced here Python sets are not json serializable

Not all datatypes can be json serialized . I guess pickle module will serve your purpose.

 pip3 install --trusted-host pypi.org --trusted-host files.pythonhosted.org <app>

I was missing a dependency somewhere else along the line, so I installed the other requirements for the project like this:

pip install --user -r requirements.txt

Threading is another possible solution. Although the Celery based solution is better for applications at scale, if you are not expecting too much traffic on the endpoint in question, threading is a viable alternative.

This solution is based on Miguel Grinberg's PyCon 2016 Flask at Scale presentation, specifically slide 41 in his slide deck. His code is also available on github for those interested in the original source.

From a user perspective the code works as follows:

1. You make a call to the endpoint that performs the long running task.
2. This endpoint returns 202 Accepted with a link to check on the task status.
3. Calls to the status link returns 202 while the taks is still running, and returns 200 (and the result) when the task is complete.

To convert an api call to a background task, simply add the @async_api decorator.

Here is a fully contained example:

from flask import Flask, g, abort, current_app, request, url_for
from werkzeug.exceptions import HTTPException, InternalServerError
from flask_restful import Resource, Api

This is what worked for me on Windows. The cause being multiple python installations

1. update path with correct python
2. uninstall pip using python -m pip uninstall pip setuptools
3. restart windows didn't work until a restart

This program will open 26 sockets where you would be able to connect a lot of TCP clients to it.

You'd have to use WebSockets (or some similar protocol module e.g. as supported by the Flash plugin) because a normal browser application simply can't open a pure TCP socket.

The Socket.IO module available for node.js can help a lot, but note that it is not a pure WebSocket module in its own right.

It's actually a more generic communications module that can run on top of various other network protocols, including WebSockets, and Flash sockets.

Hence if you want to use Socket.IO on the server end you must also use their client code and objects. You can't easily make raw WebSocket connections to a socket.io server as you'd have to emulate their message protocol.

You could use an import and single line code like this:

import ctypes  # An included library with Python install.   
ctypes.windll.user32.MessageBoxW(0, "Your text", "Your title", 1)

Or define a function (Mbox) like so:

import ctypes  # An included library with Python install.
def Mbox(title, text, style):
    return ctypes.windll.user32.MessageBoxW(0, text, title, style)
Mbox('Your title', 'Your text', 1)

Note the styles are as follows:

##  Styles:
##  0 : OK
##  1 : OK | Cancel
##  2 : Abort | Retry | Ignore
##  3 : Yes | No | Cancel
##  4 : Yes | No
##  5 : Retry | Cancel 
##  6 : Cancel | Try Again | Continue

Have fun!

Note: edited to use MessageBoxW instead of MessageBoxA

Apache Thrift is a cross-language RPC option developed at Facebook. Works over sockets, function signatures are defined in text files in a language-independent way.

The following code allows you to benefit from all SSL validation checks (e.g. date validity, CA certificate chain ...) EXCEPT a pluggable verification step e.g. to verify the hostname or do other additional certificate verification steps.

from httplib import HTTPSConnection
import ssl


def create_custom_HTTPSConnection(host):

    def verify_cert(cert, host):
        # Write your code here
        # You can certainly base yourself on ssl.match_hostname
        # Raise ssl.CertificateError if verification fails
        print 'Host:', host
        print 'Peer cert:', cert

    class CustomHTTPSConnection(HTTPSConnection, object):
        def connect(self):
            super(CustomHTTPSConnection, self).connect()
            cert = self.sock.getpeercert()
            verify_cert(cert, host)

    context = ssl.create_default_context()
    context.check_hostname = False
    return CustomHTTPSConnection(host=host, context=context)


if __name__ == '__main__':
    # try expired.badssl.com or self-signed.badssl.com !
    conn = create_custom_HTTPSConnection('badssl.com')
    conn.request('GET', '/')
    conn.getresponse().read()

Have a look at fabric.transfer.

from fabric import Connection

with Connection(host="hostname", 
                user="admin", 
                connect_kwargs={"key_filename": "/home/myuser/.ssh/private.key"}
               ) as c:
    c.get('/foo/bar/file.txt', '/tmp/')

If all the cells are under one column, you could just filter the column and then select "(blank)" and then insert any value into the cells. But be careful, press "alt + 4" to make sure you are inserting value into the visible cells only.

below works for mysql

update table1 INNER JOIN table2 on table1.col1 =  table2.col1
set table1.col1 =  table2.col2

To determine if the array is sparse, it may help to get a proportion of nan values

np.isnan(ndarr).sum() / ndarr.size

If that proportion exceeds a threshold, then use a sparse array, e.g. - https://sparse.pydata.org/en/latest/

Copy "libgcc_s_dw2-1.dll" to were make.exe is. (If you are using Msys, copy it to \msys\bin) Make sure that the path to make.exe is set in the env. PATH (if make.exe is in a folder "bin", most likely, and you have msys, it's \msys\bin) Compile, rund, debug, etc. happy.

You can use this free service: https://www.smtpjs.com

1. Include the script:

<script src="https://smtpjs.com/v2/smtp.js"></script>

2. Send an email using:

Email.send(
  "[email protected]",
  "[email protected]",
  "This is a subject",
  "this is the body",
  "smtp.yourisp.com",
  "username",
  "password"
);

Using break as well as continue in a for loop is perfectly fine.

It simplifies the code and improves its readability.

Official Definition

From the reference docs of Comparable.compareTo(T):

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

The implementor must ensure sgn(x.compareTo(y)) == -sgn(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception iff y.compareTo(x) throws an exception.)

The implementor must also ensure that the relation is transitive: (x.compareTo(y)>0 && y.compareTo(z)>0) implies x.compareTo(z)>0.

Finally, the implementor must ensure that x.compareTo(y)==0 implies that sgn(x.compareTo(z)) == sgn(y.compareTo(z)), for all z.

It is strongly recommended, but not strictly required that (x.compareTo(y)==0) == (x.equals(y)). Generally speaking, any class that implements the Comparable interface and violates this condition should clearly indicate this fact. The recommended language is "Note: this class has a natural ordering that is inconsistent with equals."

In the foregoing description, the notation sgn(expression) designates the mathematical signum function, which is defined to return one of -1, 0, or 1 according to whether the value of expression is negative, zero or positive.

My Version

In short:

this.compareTo(that)

returns

• a negative int if this < that
• 0 if this == that
• a positive int if this > that

where the implementation of this method determines the actual semantics of < > and == (I don't mean == in the sense of java's object identity operator)

Examples

"abc".compareTo("def")

will yield something smaller than 0 as abc is alphabetically before def.

Integer.valueOf(2).compareTo(Integer.valueOf(1))

will yield something larger than 0 because 2 is larger than 1.

Some additional points

Note: It is good practice for a class that implements Comparable to declare the semantics of it's compareTo() method in the javadocs.

Note: you should read at least one of the following:

• the Object Ordering section of the Collection Trail in the Sun Java Tutorial
• Effective Java by Joshua Bloch, especially item 12: Consider implementing Comparable
• Java Generics and Collections by Maurice Naftalin, Philip Wadler, chapter 3.1: Comparable

Warning: you should never rely on the return values of compareTo being -1, 0 and 1. You should always test for x < 0, x == 0, x > 0, respectively.

//initialize the 2D vector first

vector<vector<int>> matrix;

//initialize the 1D vector you would like to insert into matrix

vector<int> row;

//initializing row with values

row.push_back(val1);

row.push_back(val2);

//now inserting values into matrix

matrix.push_back(row);

//output- [[val1,val2]]

To clarify why the other answers can not work:

1. System.gc() (along with Runtime.getRuntime().gc(), which does the exact same thing) hints that you want stuff destroyed. Vaguely. The JVM is free to ignore requests to run a GC cycle, if it doesn't see the need for one. Plus, unless you've nulled out all reachable references to the object, GC won't touch it anyway. So A and B are both disqualified.

2. Runtime.getRuntime.gc() is bad grammar. getRuntime is a function, not a variable; you need parentheses after it to call it. So B is double-disqualified.

3. Object has no delete method. So C is disqualified.

4. While Object does have a finalize method, it doesn't destroy anything. Only the garbage collector can actually delete an object. (And in many cases, they technically don't even bother to do that; they just don't copy it when they do the others, so it gets left behind.) All finalize does is give an object a chance to clean up before the JVM discards it. What's more, you should never ever be calling finalize directly. (As finalize is protected, the JVM won't let you call it on an arbitrary object anyway.) So D is disqualified.

5. Besides all that, object.doAnythingAtAllEvenCommitSuicide() requires that running code have a reference to object. That alone makes it "alive" and thus ineligible for garbage collection. So C and D are double-disqualified.

Currently it only works for the .dropdown-menu:

.dropdown-menu .divider {
  height: 1px;
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

If you want it for other use, in your own css, following the bootstrap.css create another one:

.divider {
  height: 1px;
  width:100%;
  display:block; /* for use on default inline elements like span */
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

You can use a bind variable at the SQLPlus level to do this. Of course you have little control over the formatting of the output.

VAR x REFCURSOR;
EXEC GetGrantListByPI(args, :x);
PRINT x;

if you need to run the delete/insert/update you could also run dynamic statements. i.e.:

declare 
    @v_dynDelete                 NVARCHAR(500);

 SET @v_dynDelete = 'DELETE some_table;'; 
 EXEC @v_dynDelete

you can use jquery dialog widget

http://jqueryui.com/demos/dialog/

isset($_POST['fromPerson']) 

You can prevent the crash from happening by safely unwrapping cell.labelTitle with an if let statement.

if let label = cell.labelTitle{
    label.text = "This is a title"
}

You will still have to do some debugging to see why you are getting a nil value there though.

You can use arguments with default values.

def someMethod(def mandatory,def optional=null){}

if argument "optional" not exist, it turns to "null".

Why don't you introduce a service layer. then your controller will be lean and more readable, then your all controller functions will be pure actions. you can decompose business logic as you much as you need within service layer . code reusability is hight . no impact on models and repositories.

There was a time when adding strings into an array and finalising the string by using join was the fastest/best method. These days browsers have highly optimised string routines and it is recommended that + and += methods are fastest/best

This has worked for me in turning "//" into just "/".

str.replace(/\/\//g, '/');

For me, the Target Framework was the issue.

My project's Target Framework was 4.5.2 and the referenced project's Target Framework was 4.6.1.

Once I updated my project's Target Framework to 4.6.1, the issue got fixed.

If you're using FireFox, Fiddler's add-on will automatically configure it to not ignore localhost when capturing traffic. If traffic from localhost is still (or suddenly) not appearing, try disabling and re-enabling traffic capture from Fiddler to goad the add-on into fixing the proxy configuration.

If you have your dates in DateTime variables, they don't have a format.

You can use the Date property to return a DateTime value with the time portion set to midnight. So, if you have:

DateTime dt1 = DateTime.Parse("07/12/2011");
DateTime dt2 = DateTime.Now;

if(dt1.Date > dt2.Date)
{
     //It's a later date
}
else
{
     //It's an earlier or equal date
}

I have just made a solution for it. I made a library for this to do that in a reusable way that's why you don't need to recode in your XML. Here is documentation on how to use it in Java and Kotlin. First, initialize it from an activity from where you want to show the overlay-

AppWaterMarkBuilder.doConfigure()
                .setAppCompatActivity(MainActivity.this)
                .setWatermarkProperty(R.layout.layout_water_mark)
                .showWatermarkAfterConfig();

Then you can hide and show it from anywhere in your app -

  /* For hiding the watermark*/
  AppWaterMarkBuilder.hideWatermark() 

  /* For showing the watermark*/
  AppWaterMarkBuilder.showWatermark()

Unfortunately, WebKit browsers do not support styling of <option> tags yet, except for color and background-color.

The most widely used cross browser solution is to use <ul> / <li> and style them using CSS. Frameworks like Bootstrap do this well.

That last contribution's use of contains(x,y) won't work directly on the result of getBounds() (except, by coincidence, when using "left" drawables). The getBounds method only provides the Rect defining points of the drawable item normalized with origin at 0,0 - so, you actually need to do the math of the original post to find out if the click is in the area of the drawable in the context of the containing EditText's dimensions, but change it for top, right, left etc. Alternatively you could describe a Rect that has coordinates actually relative to its position in the EditText container and use contains(), although in the end you're doing the same math.

Combining them both gives you a pretty complete solution, I only added an instance attribute consumesEvent that lets the API user decide if the click event should be passed on or not by using its result to set ACTION_CANCEL or not.

Also, I can't see why the bounds and actionX, actionY values are instance attributes rather than just local on the stack.

Here's a cutout from an implementation based on the above that I put together. It fixes an issue that to properly consume the event you need to return false. It adds a "fuzz" factor to. In my use case of a Voice control icon in an EditText field, I found it hard to click, so the fuzz increases the effective bounds that are considered clicking the drawable. For me 15 worked well. I only needed drawableRight so I didn't plug the math in the others, to save some space, but you see the idea.

This old chestnut...

In short, you should be using require and letting node handle the parsing as part of the require call, not outsourcing it to a 3rd party module. You should also be taking care that your configs are bulletproof, which means you should check the returned data carefully.

But for brevity's sake, consider the following example:

For Example, let's say I have a config file 'admins.json' in the root of my app containing the following:

[{
  "userName": "tech1337",
  "passSalted": "xxxxxxxxxxxx"
}]

Note the quoted keys, "userName", "passSalted"!

I can do the following and get the data out of the file with ease.

let admins = require('~/app/admins.json');
console.log(admins[0].userName);

Now the data is in and can be used as a regular (or array of) object.

I've found the answer from these two websites: Net Maniac and Aimred.

You need to have version > 0.8 of rake to use this technique

The normal rake task description is this:

desc 'Task Description'
task :task_name => [:depends_on_taskA, :depends_on_taskB] do
  #interesting things
end

To pass arguments, do three things:

1. Add the argument names after the task name, separated by commas.
2. Put the dependencies at the end using :needs => [...]
3. Place |t, args| after the do. (t is the object for this task)

To access the arguments in the script, use args.arg_name

desc 'Takes arguments task'
task :task_name, :display_value, :display_times, :needs => [:depends_on_taskA, :depends_on_taskB] do |t, args|
  args.display_times.to_i.times do
    puts args.display_value
  end
end

To call this task from the command line, pass it the arguments in []s

rake task_name['Hello',4]

will output

Hello
Hello
Hello
Hello

and if you want to call this task from another task, and pass it arguments, use invoke

task :caller do
  puts 'In Caller'
  Rake::Task[:task_name].invoke('hi',2)
end

then the command

rake caller

will output

In Caller
hi
hi

I haven't found a way to pass arguments as part of a dependency, as the following code breaks:

task :caller => :task_name['hi',2]' do
   puts 'In Caller'
end

location.href = location.href;

You can try my lib for multiple bluetooth connection :

http://arissa34.github.io/Android-Multi-Bluetooth-Library/

If you commit it, you could also cherry-pick the single commit ID. I do this often when I start work in master, and then want to create a local branch before I push up to my origin/.

git cherry-pick <commitID>

There is alot you can do with cherry-pick, as described here, but this could be a use-case for you.

There is no hard and fast rule.

Here are some rules to make code thread safe in .NET and why these are not good rules:

1. Function and all functions it calls must be pure (no side effects) and use local variables. Although this will make your code thread-safe, there is also very little amount of interesting things you can do with this restriction in .NET.
2. Every function that operates on a common object must lock on a common thing. All locks must be done in same order. This will make the code thread safe, but it will be incredibly slow, and you might as well not use multiple threads.
3. ...

There is no rule that makes the code thread safe, the only thing you can do is make sure that your code will work no matter how many times is it being actively executed, each thread can be interrupted at any point, with each thread being in its own state/location, and this for each function (static or otherwise) that is accessing common objects.

Perhaps:

Sub dateCNV()
    Dim N As Long, r As Range, s As String
    N = Cells(Rows.Count, "A").End(xlUp).Row
    For i = 1 To N
        Set r = Cells(i, "A")
        s = r.Text
        r.Clear
        r.Value = DateSerial(Left(s, 4), Mid(s, 6, 2), Right(s, 2))
    Next i
End Sub

This assumes that column A contains text values like 2013-12-25 with no header cell.

I had the same problem I removed the @Autowired Annotation from the controller. If your repository is a class then the Autowired Annotation is needed to use the repository but when it is an interface you do not need to add the @Autowired Annotation from my experience.

For those not willing to use jQuery here is a Vanilla Javascript way of doing the same using classList:

function runOnScroll() {
    var element = document.getElementsByTagName('nav')  ;
    if(document.body.scrollTop >= 50) {
        element[0].classList.add('shrink')
    } else {
        element[0].classList.remove('shrink')
    }
    console.log(topMenu[0].classList)

};

There might be a nicer way of doing it using toggle, but the above works fine in Chrome

Inspired by philcruz's Regular Expression solution, I've made a pure LINQ solution

public static string PureAscii(this string source, char nil = ' ')
{
    var min = '\u0000';
    var max = '\u007F';
    return source.Select(c => c < min ? nil : c > max ? nil : c).ToText();
}

public static string ToText(this IEnumerable<char> source)
{
    var buffer = new StringBuilder();
    foreach (var c in source)
        buffer.Append(c);
    return buffer.ToString();
}

This is untested code.

I was trying to do the same thing, but with the added complexity that I was trying to do it from Java. So on one machine running java, I was trying to run a script on another machine, in the background (with nohup).

From the command line, here is what worked: (you may not need the "-i keyFile" if you don't need it to ssh to the host)

ssh -i keyFile user@host bash -c "\"nohup ./script arg1 arg2 > output.txt 2>&1 &\""

Note that to my command line, there is one argument after the "-c", which is all in quotes. But for it to work on the other end, it still needs the quotes, so I had to put escaped quotes within it.

From java, here is what worked:

ProcessBuilder b = new ProcessBuilder("ssh", "-i", "keyFile", "bash", "-c",
 "\"nohup ./script arg1 arg2 > output.txt 2>&1 &\"");
Process process = b.start();
// then read from process.getInputStream() and close it.

It took a bit of trial & error to get this working, but it seems to work well now.

OK, the first thing to note is that <i> has been deprecated, and shouldn't be used <i> has not been deprecated, but I still do not recommend using it—see the comments for details. This is because it goes entirely against keeping presentation in the presentation layer, which you've pointed out. Similarly, <span class="italic"> seems to break the mold too.

So now we have two real ways of doing things: <em> and <span class="footnote">. Remember that em stands for emphasis. When you wish to apply emphasis to a word, phrase or sentence, stick it in <em> tags regardless of whether you want italics or not. If you want to change the styling in some other way, use CSS: em { font-weight: bold; font-style: normal; }. Of course, you can also apply a class to the <em> tag: if you decide you want certain emphasised phrases to show up in red, give them a class and add it to the CSS:

Fancy some <em class="special">shiny</em> text?

em { font-weight: bold; font-style: normal; }
em.special { color: red; }

If you're applying italics for some other reason, go with the other method and give the section a class. That way, you can change its styling whenever you want without adjusting the HTML. In your example, footnotes should not be emphasised—in fact, they should be de-emphasised, as the point of a footnote is to show unimportant but interesting or useful information. In this case, you're much better off applying a class to the footnote and making it look like one in the presentation layer—the CSS.

I am using git push <remote-name> tag <tag-name> to ensure that I am pushing a tag. I use it like: git push origin tag v1.0.1. This pattern is based upon the documentation (man git-push):

OPTIONS
   ...
   <refspec>...
       ...
       tag <tag> means the same as refs/tags/<tag>:refs/tags/<tag>.

I think you need to do is to transform your data from object not to JSON string, but to url params.

From Ben Nadel's blog.

By default, the $http service will transform the outgoing request by serializing the data as JSON and then posting it with the content- type, "application/json". When we want to post the value as a FORM post, we need to change the serialization algorithm and post the data with the content-type, "application/x-www-form-urlencoded".

Example from here.

$http({
    method: 'POST',
    url: url,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'},
    transformRequest: function(obj) {
        var str = [];
        for(var p in obj)
        str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
        return str.join("&");
    },
    data: {username: $scope.userName, password: $scope.password}
}).then(function () {});

For completeness, also look into the local storage capabilities & sessionStorage of HTML5. These are supported in the latest versions of all modern browsers, and are much easier to use and less fiddly than cookies.

http://www.w3.org/TR/2009/WD-webstorage-20091222/

https://www.w3.org/TR/webstorage/. (second edition)

Here are some sample code for setting and getting the values using sessionStorage and localStorage :

 // HTML5 session Storage
 sessionStorage.setItem("variableName","test");
 sessionStorage.getItem("variableName");


//HTML5 local storage 
localStorage.setItem("variableName","Text");
// Receiving the data:
localStorage.getItem("variableName");

Apple have recently made new changes in APNs and now apple insist us to use "Token Based Authentication" instead of the traditional ways which we are using for push notification.

So does not need to worry about their expiration and this p8 certificates are for both development and production so again no need to generate 2 separate certificate for each mode.

To generate p8 just go to your developer account and select this option "Apple Push Notification Authentication Key (Sandbox & Production)"

Then will generate directly p8 file.

I hope this will solve your issue.

The easiest way is to call a function for the style, and have the function return the correct style.

<div style="{{functionThatReturnsStyle()}}"></div>

And in your controller:

$scope.functionThatReturnsStyle = function() {
  var style1 = "width: 300px";
  var style2 = "width: 200px";
  if(condition1)
     return style1;
  if(condition2)
     return style2;
}

If you are trying to pull the value from a field, you could use:

select extract(month from [field_name])
from [table_name]

You can also insert day or year for the "month" extraction value above.

The comments state the objective is to print to 2 decimal places.

There's a simple answer for Python 3:

>>> num=3.65
>>> "The number is {:.2f}".format(num)
'The number is 3.65'

or equivalently with f-strings (Python 3.6+):

>>> num = 3.65
>>> f"The number is {num:.2f}"
'The number is 3.65'

As always, the float value is an approximation:

>>> "{}".format(num)
'3.65'
>>> "{:.10f}".format(num)
'3.6500000000'
>>> "{:.20f}".format(num)
'3.64999999999999991118'

I think most use cases will want to work with floats and then only print to a specific precision.

Those that want the numbers themselves to be stored to exactly 2 decimal digits of precision, I suggest use the decimal type. More reading on floating point precision for those that are interested.

Something like this worked for me (references columns C and D from the row 8 till the end of the columns, in Excel 2013 if relevant):

=SUMIFS(INDIRECT(ADDRESS(ROW(D$8), COLUMN())&":"&ADDRESS(ROWS($C:$C), COLUMN())),INDIRECT("C$8:C"&ROWS($C:$C)),$C$2)

We can directly subtract dates to get difference in Days.

    SET SERVEROUTPUT ON ;
    DECLARE
        V_VAR NUMBER;
    BEGIN
         V_VAR:=TO_DATE('2000-01-02', 'YYYY-MM-DD') - TO_DATE('2000-01-01', 'YYYY-MM-DD') ;
         DBMS_OUTPUT.PUT_LINE(V_VAR);
    END;

This will only work to column Z, but you can drag this horizontally and vertically.

=INDIRECT("'"&$D$2&"'!"&CHAR((COLUMN()+64))&ROW())

Why not:

ls *.{mp3,exe,mp4}

I'm not sure where I learned it - but I've been using this.

I have edited the code from one of the example here to use jquery. It's still not 100% jquery though. Any thoughts on the two different versions, like what are the pros and cons of each?

function column_sort() {
    getCellValue = (tr, idx) => $(tr).find('td').eq( idx ).text();

    comparer = (idx, asc) => (a, b) => ((v1, v2) => 
        v1 !== '' && v2 !== '' && !isNaN(v1) && !isNaN(v2) ? v1 - v2 : v1.toString().localeCompare(v2)
        )(getCellValue(asc ? a : b, idx), getCellValue(asc ? b : a, idx));
    
    table = $(this).closest('table')[0];
    tbody = $(table).find('tbody')[0];

    elm = $(this)[0];
    children = elm.parentNode.children;
    Array.from(tbody.querySelectorAll('tr')).sort( comparer(
        Array.from(children).indexOf(elm), table.asc = !table.asc))
        .forEach(tr => tbody.appendChild(tr) );
}

table.find('thead th').on('click', column_sort);

Comparing dates in JavaScript is quite easy... JavaScript has built-in comparison system for dates which makes it so easy to do the comparison...

Just follow these steps for comparing 2 dates value, for example you have 2 inputs which each has a Date value in String and you to compare them...

1. you have 2 string values you get from an input and you'd like to compare them, they are as below:

var date1 = '01/12/2018';
var date2 = '12/12/2018';

2. They need to be Date Object to be compared as date values, so simply convert them to date, using new Date(), I just re-assign them for simplicity of explanation, but you can do it anyway you like:

date1 = new Date(date1);
date2 = new Date(date2);

3. Now simply compare them, using the > < >= <=

date1 > date2;  //false
date1 < date2;  //true
date1 >= date2; //false
date1 <= date2; //true

Try this

li = soup.find('li', {'class': 'text'})
children = li.findChildren("a" , recursive=False)
for child in children:
    print(child)

If you have conditional and would like to unwrap and compare, how about taking advantage of the short-circuit evaluation of compound boolean expression as in

if xyz != nil && xyz! == "some non-nil value" {

}

Granted, this is not as readable as some of the other suggested posts, but gets the job done and somewhat succinct than the other suggested solutions.

out.write((cmd + "\n").getBytes(CHARSET_NAME));
out.write(("exit" + "\n").getBytes(CHARSET_NAME));
out.flush();

tl;dr:

There are 3 main issues with multithreading:

1) Race Conditions

2) Caching / stale memory

3) Complier and CPU optimisations

volatile can solve 2 & 3, but can't solve 1. synchronized/explicit locks can solve 1, 2 & 3.

Elaboration:

1) Consider this thread unsafe code:

x++;

While it may look like one operation, it's actually 3: reading the current value of x from memory, adding 1 to it, and saving it back to memory. If few threads try to do it at the same time, the result of the operation is undefined. If x originally was 1, after 2 threads operating the code it may be 2 and it may be 3, depending on which thread completed which part of the operation before control was transferred to the other thread. This is a form of race condition.

Using synchronized on a block of code makes it atomic - meaning it make it as if the 3 operations happen at once, and there's no way for another thread to come in the middle and interfere. So if x was 1, and 2 threads try to preform x++ we know in the end it will be equal to 3. So it solves the race condition problem.

synchronized (this) {
   x++; // no problem now
}

Marking x as volatile does not make x++; atomic, so it doesn't solve this problem.

2) In addition, threads have their own context - i.e. they can cache values from main memory. That means that a few threads can have copies of a variable, but they operate on their working copy without sharing the new state of the variable among other threads.

Consider that on one thread, x = 10;. And somewhat later, in another thread, x = 20;. The change in value of x might not appear in the first thread, because the other thread has saved the new value to its working memory, but hasn't copied it to the main memory. Or that it did copy it to the main memory, but the first thread hasn't updated its working copy. So if now the first thread checks if (x == 20) the answer will be false.

Marking a variable as volatile basically tells all threads to do read and write operations on main memory only. synchronized tells every thread to go update their value from main memory when they enter the block, and flush the result back to main memory when they exit the block.

Note that unlike data races, stale memory is not so easy to (re)produce, as flushes to main memory occur anyway.

3) The complier and CPU can (without any form of synchronization between threads) treat all code as single threaded. Meaning it can look at some code, that is very meaningful in a multithreading aspect, and treat it as if it’s single threaded, where it’s not so meaningful. So it can look at a code and decide, in sake of optimisation, to reorder it, or even remove parts of it completely, if it doesn’t know that this code is designed to work on multiple threads.

Consider the following code:

boolean b = false;
int x = 10;

void threadA() {
    x = 20;
    b = true;
}

void threadB() {
    if (b) {
        System.out.println(x);
    }
}

You would think that threadB could only print 20 (or not print anything at all if threadB if-check is executed before setting b to true), as b is set to true only after x is set to 20, but the compiler/CPU might decide to reorder threadA, in that case threadB could also print 10. Marking b as volatile ensures that it won’t be reordered (or discarded in certain cases). Which mean threadB could only print 20 (or nothing at all). Marking the methods as syncrhonized will achieve the same result. Also marking a variable as volatile only ensures that it won’t get reordered, but everything before/after it can still be reordered, so synchronization can be more suited in some scenarios.

Note that before Java 5 New Memory Model, volatile didn’t solve this issue.

I've compared performance (space and time) for a number of ways to store numpy arrays. Few of them support multiple arrays per file, but perhaps it's useful anyway.

Npy and binary files are both really fast and small for dense data. If the data is sparse or very structured, you might want to use npz with compression, which'll save a lot of space but cost some load time.

If portability is an issue, binary is better than npy. If human readability is important, then you'll have to sacrifice a lot of performance, but it can be achieved fairly well using csv (which is also very portable of course).

More details and the code are available at the github repo.

var Test = (from row in Dataset1.Tables[0].AsEnumerable()
            select row.Field<string>("attribute1_name") + row.Field<int>("attribute2_name")).Distinct();

You can use Visual Studio for Android Development. See a nice article on it here

Update your SP and handle exception in it using declare handler with get diagnostics so that you will know if there is an exception. e.g.

CREATE DEFINER=`root`@`localhost` PROCEDURE `validar_egreso`(
IN codigo_producto VARCHAR(100),
IN cantidad INT,
OUT valido INT(11)
)
BEGIN
DECLARE EXIT HANDLER FOR SQLEXCEPTION
BEGIN
    GET DIAGNOSTICS CONDITION 1
    @p1 = RETURNED_SQLSTATE, @p2 = MESSAGE_TEXT;
    SELECT @p1, @p2;
END
DECLARE resta INT(11);
SET resta = 0;

SELECT (s.stock - cantidad) INTO resta
FROM stock AS s
WHERE codigo_producto = s.codigo;

IF (resta > s.stock_minimo) THEN
    SET valido = 1;
ELSE
    SET valido = -1;
END IF;
SELECT valido;
END

json loads -> returns an object from a string representing a json object.

json dumps -> returns a string representing a json object from an object.

load and dump -> read/write from/to file instead of string

Why not loop through the inputs and then add onclick handlers to each?

You don't have to do this in HTML, but you can add a handler to each button like:

button.onclick = function(){ DoStuff(this.value); return false; } // return false; so that form does not submit

Then your function could "do stuff" according to whichever value you passed:

function DoStuff(val) {
    if( val === "Val 1" ) {
        // Do some stuff
    }
    // Do other stuff
}

a % b

in c++ default:

(-7/3) => -2
-2 * 3 => -6
so a%b => -1

(7/-3) => -2
-2 * -3 => 6
so a%b => 1

in python:

-7 % 3 => 2
7 % -3 => -2

in c++ to python:

(b + (a%b)) % b

If you have supporting indexes, and relatively high counts, something like this may be considerably faster than the solutions suggested:

SELECT name, MAX(Rcount) + MAX(Acount) AS TotalCount
FROM (
  SELECT name, COUNT(*) AS Rcount, 0 AS Acount
  FROM Results GROUP BY name
  UNION ALL
  SELECT name, 0, count(*)
  FROM Archive_Results
  GROUP BY name
) AS Both
GROUP BY name
ORDER BY name;

Say suppose, you have

File f  = new File("SomeFile");
f.length();

You need not close the Files, because its just the representation of a path.

You should always consider to close only reader/writers and in fact streams.

Use the ? symbol (encoded as ⚲ or ⚲), and rotate it to achieve the desired effect:

<div style="-webkit-transform: rotate(45deg); 
               -moz-transform: rotate(45deg); 
                 -o-transform: rotate(45deg);
                    transform: rotate(45deg);">
    &#9906;
</div>

It rotates a symbol :)

This error arise from the fact that you are trying to define an object of shape (0,) as an object of shape (2,). If you append what you want without forcing it to be equal to result[0] there is no any issue:

b = np.append([result[0]], [1,2])

But when you define result[0] = b you are equating objects of different shapes, and you can not do this. What are you trying to do?

Depending. If the order of keys in the object are not of importance, and I don't need to know the prototypes of the said object. Using always do the job.

const object = {};
JSON.stringify(object) === "{}" will pass but {} === "{}" will not

I actually think it may retain cached information when you close out the UIWebView. I've tried removing a UIWebView from my UIViewController, releasing it, then creating a new one. The new one remembered exactly where I was at when I went back to an address without having to reload everything (it remembered my previous UIWebView was logged in).

So a couple of suggestions:

[[NSURLCache sharedURLCache] removeCachedResponseForRequest:NSURLRequest];

This would remove a cached response for a specific request. There is also a call that will remove all cached responses for all requests ran on the UIWebView:

[[NSURLCache sharedURLCache] removeAllCachedResponses];

After that, you can try deleting any associated cookies with the UIWebView:

for(NSHTTPCookie *cookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]) {

    if([[cookie domain] isEqualToString:someNSStringUrlDomain]) {

        [[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie];
    }
}

Swift 3:

// Remove all cache 
URLCache.shared.removeAllCachedResponses()

// Delete any associated cookies     
if let cookies = HTTPCookieStorage.shared.cookies {
    for cookie in cookies {
        HTTPCookieStorage.shared.deleteCookie(cookie)
    }
}

use this as somethink

"C:/Program Files (x86)/Nox/bin/nox_adb" install -r app.apk

where

"path_to_executable" commands_argument

Login into your server using a shell program like putty.

Type in the following command on the command line

zcat DB_File_Name.sql.gz | mysql -u username -p Target_DB_Name

where

DB_File_Name.sql.gz = full path of the sql.gz file to be imported

username = your mysql username

Target_DB_Name = database name where you want to import the database

When you hit enter in the command line, it will prompt for password. Enter your MySQL password.

You are done!

There's also php2xmi. You have to do a bit of manual work, but it generates all the classes, so all you have to do is to drag them into a classdiagram in Umbrello.

Otherwise, generating a diagram with the use of reflection and graphviz, is fairly simple. I have a snippet over here, that you can use as a starting point.

One possibility that the above answers don't address is that you may not have an ssh access from your shell. That is, you may be in a network (some college networks do this) where ssh service is blocked.In that case you will not only be able to get github services but also any other ssh services. You can test if this is the problem by trying to use any other ssh service.This was the case with me.

If you manually write out the query with static date values (e.g. '2009-10-29 13:13:07.440') do you get any rows?

So, you are saying that the following two queries produce correct results:

SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat 
    INNER JOIN PubAdvertiser AS pa 
        ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > '2009-10-29 13:13:07.440') AND (pa.AdvertiserID = 12345))

DECLARE @sp_Date DATETIME
SET @sp_Date = '2009-10-29 13:13:07.440'

SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat 
    INNER JOIN PubAdvertiser AS pa 
        ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > @sp_Date) AND (pa.AdvertiserID = 12345))

myList.Where(item=>item.Name == nameToExtract)

I found this worked for me.

$username = 'user'
$password = 'password'

$securePassword = ConvertTo-SecureString $password -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential $username, $securePassword
Start-Process Notepad.exe -Credential $credential

Updated: changed to using single quotes to avoid special character issues noted by Paddy.

@kajetons' answer is fully functional.

You can also pass multiple variables by passing them like: use($var1, $var2)

DB::table('users')->where(function ($query) use ($activated,$var2) {
    $query->where('activated', '=', $activated);
    $query->where('var2', '>', $var2);
})->get();

I can't comment yet.

Same as Kevin but with different UI step:

This may not be the exact answer for the OP, but is the answer to the Title of the question: How to Update Gradle in Android Studio (AS):

• Get latest version supported by AS: http://www.gradle.org/downloads (Currently 1.9, 1.10 is NOT supported by AS yet)
• Install: Unzip to anywhere like near where AS is installed: C:\Users[username]\gradle-1.9\
• Open AS: File->Settings->Build, Execution, Deployment->Build Tools-> Gradle->Service directory path: (Change to folder you set above) ->Click ok. Status on bottom should indicate it's busy & error should be fixed. Might have to restart AS

print ''.join(file('example.txt'))

How does it work if you only are using visible-md at Col4 instead? Do you use the -lg at all? If not this might work.

<div class="container">
    <div class="row">
        <div class="col-xs-4 col-sm-2 col-md-1" align="center">
            Col1
        </div>
        <div class="col-xs-4 col-sm-2" align="center">
            Col2
        </div>
        <div class="hidden-xs col-sm-6 col-md-5" align="center">

</script>

For me, the easiest solution would be keep value when count is equal to the maximum. Therefore, the following one line command is enough :

df[df['count'] == df.groupby(['Mt'])['count'].transform(max)]

You can also use eye function of numpy:

numpy.eye(number of classes)[vector containing the labels]

=A1/(24*60*60) + DATE(1970;1;1) should work with seconds.

=(A1/86400/1000)+25569 if your time is in milliseconds, so dividing by 1000 gives use the correct date

Don't forget to set the type to Date on your output cell. I tried it with this date: 1504865618099 which is equal to 8-09-17 10:13.

You're passing the same model to the partial view as is being passed to the main view, and they are different types. The model is a DbSet of Notes, where you need to pass in a single Note.

You can do this by adding a parameter, which I'm guessing as it's the create form would be a new Note

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

RecyclerView was created as a ListView improvement, so yes, you can create an attached list with ListView control, but using RecyclerView is easier as it:

1. Reuses cells while scrolling up/down : this is possible with implementing View Holder in the ListView adapter, but it was an optional thing, while in the RecycleView it's the default way of writing adapter.

2. Decouples list from its container : so you can put list items easily at run time in the different containers (linearLayout, gridLayout) with setting LayoutManager.

mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view); mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); mRecyclerView.setLayoutManager(new GridLayoutManager(this, 2));

3. Animates common list actions : Animations are decoupled and delegated to ItemAnimator. There is more about RecyclerView, but I think these points are the main ones.

So, to conclude, RecyclerView is a more flexible control for handling "list data" that follows patterns of delegation of concerns and leaves for itself only one task - recycling items.

UPDATE Table SET Column = REPLACE(Column, char(9), '')

you are using a smart quote “ instead of " here:

git.exe clone -v “ssh://

Make sure you use the plain-old-double-quote.

According to pydoc, hasattr(obj, prop) simply calls getattr(obj, prop) and catches exceptions. So, it is just as valid to wrap the attribute access with a try statement and catch AttributeError as it is to use hasattr() beforehand.

a = SomeClass()
try:
    return a.fake_prop
except AttributeError:
    return default_value

Bill Venners: In your blog post entitled "Why REST Failed," you said that we need all four HTTP verbs—GET, POST, PUT, and DELETE— and lamented that browser vendors only GET and POST." Why do we need all four verbs? Why aren't GET and POST enough?

Elliotte Rusty Harold: There are four basic methods in HTTP: GET, POST, PUT, and DELETE. GET is used most of the time. It is used for anything that's safe, that doesn't cause any side effects. GET is able to be bookmarked, cached, linked to, passed through a proxy server. It is a very powerful operation, a very useful operation.

POST by contrast is perhaps the most powerful operation. It can do anything. There are no limits as to what can happen, and as a result, you have to be very careful with it. You don't bookmark it. You don't cache it. You don't pre-fetch it. You don't do anything with a POST without asking the user. Do you want to do this? If the user presses the button, you can POST some content. But you're not going to look at all the buttons on a page, and start randomly pressing them. By contrast browsers might look at all the links on the page and pre-fetch them, or pre-fetch the ones they think are most likely to be followed next. And in fact some browsers and Firefox extensions and various other tools have tried to do that at one point or another.

PUT and DELETE are in the middle between GET and POST. The difference between PUT or DELETE and POST is that PUT and DELETE are *idempotent, whereas POST is not. PUT and DELETE can be repeated if necessary. Let's say you're trying to upload a new page to a site. Say you want to create a new page at http://www.example.com/foo.html, so you type your content and you PUT it at that URL. The server creates that page at that URL that you supply. Now, let's suppose for some reason your network connection goes down. You aren't sure, did the request get through or not? Maybe the network is slow. Maybe there was a proxy server problem. So it's perfectly OK to try it again, or again—as many times as you like. Because PUTTING the same document to the same URL ten times won't be any different than putting it once. The same is true for DELETE. You can DELETE something ten times, and that's the same as deleting it once.

By contrast, POST, may cause something different to happen each time. Imagine you are checking out of an online store by pressing the buy button. If you send that POST request again, you could end up buying everything in your cart a second time. If you send it again, you've bought it a third time. That's why browsers have to be very careful about repeating POST operations without explicit user consent, because POST may cause two things to happen if you do it twice, three things if you do it three times. With PUT and DELETE, there's a big difference between zero requests and one, but there's no difference between one request and ten.

Please visit the url for more details. http://www.artima.com/lejava/articles/why_put_and_delete.html

Update:

Idempotent methods An idempotent HTTP method is a HTTP method that can be called many times without different outcomes. It would not matter if the method is called only once, or ten times over. The result should be the same. Again, this only applies to the result, not the resource itself. This still can be manipulated (like an update-timestamp, provided this information is not shared in the (current) resource representation.

Consider the following examples:

a = 4;

a++;

The first example is idempotent: no matter how many times we execute this statement, a will always be 4. The second example is not idempotent. Executing this 10 times will result in a different outcome as when running 5 times. Since both examples are changing the value of a, both are non-safe methods.

You need to store the psftp script (lines from open to bye) into a separate file and pass that to psftp using -b switch:

cd "C:\Program Files (x86)\PuTTY"
psftp -b "C:\path\to\script\script.txt"

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-option-b

EDIT: For username+password: As you cannot use psftp commands in a batch file, for the same reason, you cannot specify the username and the password as psftp commands. These are inputs to the open command. While you can specify the username with the open command (open <user>@<IP>), you cannot specify the password this way. This can be done on a psftp command line only. Then it's probably cleaner to do all on the command-line:

cd "C:\Program Files (x86)\PuTTY"
psftp -b script.txt <user>@<IP> -pw <PW>

And remove the open, <user> and <PW> lines from your script.txt.

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-starting
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-pw

What you are doing atm is that you run psftp without any parameter or commands. Once you exit it (like by typing bye), your batch file continues trying to run open command (and others), what Windows shell obviously does not understand.

If you really want to keep everything in one file (the batch file), you can write commands to psftp standard input, like:

(
    echo cd ...
    echo lcd ...
    echo put log.sh
) | psftp -b script.txt <user>@<IP> -pw <PW>

Another option is to left join your Results table with your existing competitors Table and find the new competitors by filtering the distinct records that don´t match int the join:

INSERT Competitors (cName)
SELECT  DISTINCT cr.Name
FROM    CompResults cr left join
        Competitors c on cr.Name = c.cName
where   c.cName is null

New syntax MERGE also offer a compact, elegant and efficient way to do that:

MERGE INTO Competitors AS Target
USING (SELECT DISTINCT Name FROM CompResults) AS Source ON Target.Name = Source.Name
WHEN NOT MATCHED THEN
    INSERT (Name) VALUES (Source.Name);

For Antlr 4 the java code generation process is below:-

java -cp antlr-4.5.3-complete.jar org.antlr.v4.Tool Exp.g

Update your jar name in classpath accordingly.

you shouldn't include c-files in other c-files. Instead create a header file where the function is declared that you want to call. Like so: file ClasseAusiliaria.h:

int addizione(int a, int b); // this tells the compiler that there is a function defined and the linker will sort the right adress to call out.

In your Main.c file you can then include the newly created header file:

#include <stdlib.h>
#include <stdio.h>
#include <ClasseAusiliaria.h>

int main(void)
{
    int risultato;
    risultato = addizione(5,6);
    printf("%d\n",risultato);
}

If, for example, x = 5 and is stored as string, you can also just:

x = x + 0

and the new x would be stored as a numeric value.

Give hibernate.connection.url as "jdbc:oracle:thin:@127.0.0.1:1521:xe" then you can solve above issue. Because oracle's default SID is "xe" so we should give like this. When I gave like this data has been inserted into DB without any SQL exceptions, it's my real time experience.

What I made, in my case I wanted to show procedure's result in dataGridView:

using (var command = new SqlCommand("ProcedureNameHere", connection) {
            // Set command type and add Parameters
            CommandType = CommandType.StoredProcedure,
            Parameters = { new SqlParameter("@parameterName",parameterValue) }
        }) 
        {
            // Execute command in Adapter and store to dataset
            var adapter = new SqlDataAdapter(command);
            var dataset = new DataSet();
            adapter.Fill(dataset);
            // Display results in DatagridView
            dataGridView1.DataSource = dataset.Tables[0];
        }

After implementing a classic pattern like

class Singleton {
  private instance: Singleton;
  
  private constructor() {}

  public getInstance() {
    if (!this.instance) { 
      this.instance = new Singleton();
    }
    return this.instance;
  }
}

I realized it's pretty useless in case you want some other class to be a singleton too. It's not extendable. You have to write that singleton stuff for every class you want to be a singleton.

Decorators for the rescue.

@singleton
class MyClassThatIsSingletonToo {}

You can write decorator by yourself or take some from npm. I found this proxy-based implementation from @keenondrums/singleton package neat enough.

When running in a CI script, you will have trouble with imperative commands as create raises an error if the resource already exists.

What you can do is applying (declarative pattern) the output of your imperative command, by using --dry-run=true and -o yaml options:

kubectl create whatever --dry-run=true -o yaml | kubectl apply -f -

The command above will not raise an error if the resource already exists (and will update the resource if needed).

This is very useful in some cases where you cannot use the declarative pattern (for instance when creating a docker-registry secret).

I have had a similar problem before where it turned out to be the web brower (chrome in my case) that was the issue.

If you are using chrome, try launching it so:

For Windows:

1) Create a shortcut to Chrome on your desktop. Right-click on the shortcut and choose Properties, then switch to “Shortcut” tab.

2) In the “Target” field, append the following: –args –disable-web-security

For Mac, Open a terminal window and run this from command-line: open ~/Applications/Google\ Chrome.app/ –args –disable-web-security

Above info from:

http://documentumcookbook.wordpress.com/2012/03/13/disable-cross-domain-javascript-security-in-chrome-for-development/

Put this right before the closing Body tag at the bottom of the page.

<script>
    if (location.hash) {
        location.href = location.hash;
    }
</script>

jQuery is actually not required.

The vertical-align css attribute doesn't do what you expect unfortunately. This article explains 2 ways to vertically align an element using css.

In general, it is considered best-practice to use relative URLs, so that your website will not be bound to the base URL of where it is currently deployed. For example, it will be able to work on localhost, as well as on your public domain, without modifications.

Try to temporarily modify request.js and harcode everywhere rejectUnauthorized = true, but it would be better to get the certificate extended as a long-term solution.

You should read-up on jQueryUI Datepicker

Once you include the relevant jQuery UI library, it's as simple as,

Script:

$(function() {
    $( "#datepicker" ).datepicker();
});

HTML:

<input type="text" id="datepicker" />

Pros:

• it is thoroughly tested for x-browser compatibility, so you won't have a problem.
• Separate css file, so you can customize it as per your liking

I had the same problem. This happened because of core library dependency. I was using javax.* . This is what i did to fix

In File->Project Structure->Dependencies I added this as as provided file, not a compile. Then re build the project.

This problem started after upgrade of android studio. But I think it happens when you try to edit you build files manually.

Use slicing, rebuilding the string minus the index you want to remove:

newstr = oldstr[:4] + oldstr[5:]

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);

Where str is your XML string. See the MSDN article for more info.

BE VERY CAREFUL, the problem may come from multibytes encoding and inappropriate PHP functions used...

It was the case for me and it took me a while to figure it out.

For example, I get the a string from MySQL using utf8mb4 (very common now to encode emojis):

$formattedString = strtolower($stringFromMysql);
$strCleaned = iconv('UTF-8', 'utf-8//TRANSLIT', $formattedString); // WILL RETURN THE ERROR 'Detected an illegal character in input string'

The problem does not stand in iconv() but stands in strtolower() in this case.

The appropriate way is to use Multibyte String Functions mb_strtolower() instead of strtolower()

$formattedString = mb_strtolower($stringFromMysql);
$strCleaned = iconv('UTF-8', 'utf-8//TRANSLIT', $formattedString); // WORK FINE

MORE INFO

More examples of this issue are available at this SO answer

PHP Manual on the Multibyte String

My solution shuffles the rows, then takes the first 75% of the rows as train and the last 25% as test. Super simples!

row_count <- nrow(orders_pivotted)
shuffled_rows <- sample(row_count)
train <- orders_pivotted[head(shuffled_rows,floor(row_count*0.75)),]
test <- orders_pivotted[tail(shuffled_rows,floor(row_count*0.25)),]

I have met this issue , the error comes out since the error transactions hasn't been ended rightly, I found the postgresql_transactions of Transaction Control command here

Transaction Control

The following commands are used to control transactions

BEGIN TRANSACTION - To start a transaction.

COMMIT - To save the changes, alternatively you can use END TRANSACTION command.

ROLLBACK - To rollback the changes.

so i use the END TRANSACTION to end the error TRANSACTION, code like this:

    for key_of_attribute, command in sql_command.items():
        cursor = connection.cursor()
        g_logger.info("execute command :%s" % (command))
        try:
            cursor.execute(command)
            rows = cursor.fetchall()
            g_logger.info("the command:%s result is :%s" % (command, rows))
            result_list[key_of_attribute] = rows
            g_logger.info("result_list is :%s" % (result_list))
        except Exception as e:
            cursor.execute('END TRANSACTION;')
            g_logger.info("error command :%s and error is :%s" % (command, e))

The Winsock2.h header file internally includes core elements from the Windows.h header file, so there is not usually an #include line for the Windows.h header file in Winsock applications. If an #include line is needed for the Windows.h header file, this should be preceded with the #define WIN32_LEAN_AND_MEAN macro. For historical reasons, the Windows.h header defaults to including the Winsock.h header file for Windows Sockets 1.1. The declarations in the Winsock.h header file will conflict with the declarations in the Winsock2.h header file required by Windows Sockets 2.0. The WIN32_LEAN_AND_MEAN macro prevents the Winsock.h from being included by the Windows.h header ..

You can display the ActiveRecord generated SQL:

And after it has run:

As rcs stated, cex will do the job in base graphics package. I reckon that you're not willing to do your graph in ggplot2 but if you do, there's a size aesthetic attribute, that you can easily control (ggplot2 has user-friendly function arguments: instead of typing cex (character expansion), in ggplot2 you can type e.g. size = 2 and you'll get 2mm point).

Here's the example:

### base graphics ###
plot(mpg ~ hp, data = mtcars, pch = 16, cex = .9)

### ggplot2 ###
# with qplot()
qplot(mpg, hp, data = mtcars, size = I(2))
# or with ggplot() + geom_point()
ggplot(mtcars, aes(mpg, hp), size = 2) + geom_point()
# or another solution:
ggplot(mtcars, aes(mpg, hp)) + geom_point(size = 2)

In my case I was facing the problem because in my tomcat process specific keystore was given using

-Djavax.net.ssl.trustStore=/pathtosomeselfsignedstore/truststore.jks

Wheras I was importing the certificate to the cacert of JRE/lib/security and the changes were not reflecting. Then I did below command where /tmp/cert1.test contains the certificate of the target server

keytool -import -trustcacerts -keystore /pathtosomeselfsignedstore/truststore.jks -storepass password123 -noprompt -alias rapidssl-myserver -file /tmp/cert1.test

We can double check if the certificate import is successful

keytool -list -v -keystore /pathtosomeselfsignedstore/truststore.jks

and see if your taget server is found against alias rapidssl-myserver

You can also use EXIT_SUCCESS instead of return 0;. The macro EXIT_SUCCESS is actually defined as zero, but makes your program more readable.

Here is one way of doing it.

If you HTML looks like this:

<div>Contact Details
    <button type="button" class="edit_button">My Button</button>
</div>

apply the following CSS:

div {
    border-bottom-width: 1px;
    border-bottom-style: solid;
    border-bottom-color: gray;
    overflow: auto;
}
.edit_button {
    float: right;
    margin: 0 10px 10px 0; /* for demo only */
}

The trick is to apply overflow: auto to the div, which starts a new block formatting context. The result is that the floated button is enclosed within the block area defined by the div tag.

You can then add margins to the button if needed to adjust your styling.

In the original HTML and CSS, the floated button was out of the content flow so the border of the div would be positioned with respect to the in-flow text, which does not include any floated elements.

This answer is based on the 2nd tip from this blog post: 28 Jupyter Notebook tips, tricks and shortcuts

You can add the following code to the top of your notebook

from IPython.core.interactiveshell import InteractiveShell
InteractiveShell.ast_node_interactivity = "all"

This tells Jupyter to print the results for any variable or statement on it’s own line. So you can then execute a cell solely containing

df1
df2

and it will "print out the beautiful tables for both datasets".

Depending on how you format (and validate!) the date entered in the textbox, you can do this:

TimeSpan time;

if (TimeSpan.TryParse(textboxTime.Text, out time))
{
   // calendarDate is the DateTime value of the calendar control
   calendarDate = calendarDate.Add(time);
}
else
{
   // notify user about wrong date format
}

Note that TimeSpan.TryParse expects the string to be in the 'hh:mm' format (optional seconds).

To call external file you can use :

load ("path\file")

Exemple: if your file.js file is on your "Documents" file (on windows OS), you can type:

load ("C:\users\user_name\Documents\file.js")

I run into this problem as well, the case with me was incorrect naming . I was migrating from local server to online server. my SQL command had "database.tablename.column" structure. the name of database in online server was different. for example my code was "pet.item.name" while it needed to be "pet_app.item.name" changing database name solved my problem.

1. Open SQL Server Configuration Manager, and then expand SQL Server 2012 Network Configuration.
2. Click Protocols for InstanceName, and then make sure TCP/IP is enabled in the right panel and double-click TCP/IP.
3. On the Protocol tab, notice the value of the Listen All item.
4. Click the IP Addresses tab: If the value of Listen All is yes, the TCP/IP port number for this instance of SQL Server 2012 is the value of the TCP Dynamic Ports item under IPAll. If the value of Listen All is no, the TCP/IP port number for this instance of SQL Server 2012 is the value of the TCP Dynamic Ports item for a specific IP address.
5. Make sure the TCP Port is 1433.
6. Click OK.

If there are any more questions, please let me know.

I have made a library SimpleHashing.Net to make the process of hashing easy with basic classes provided by Microsoft. Ordinary SHA is not really enough to have passwords stored securely anymore.

The library use the idea of hash format from Bcrypt, but since there is no official MS implementation I prefer to use what's available in the framework (i.e. PBKDF2), but it's a bit too hard out of the box.

This is a quick example how to use the library:

ISimpleHash simpleHash = new SimpleHash();

// Creating a user hash, hashedPassword can be stored in a database
// hashedPassword contains the number of iterations and salt inside it similar to bcrypt format
string hashedPassword = simpleHash.Compute("Password123");

// Validating user's password by first loading it from database by username
string storedHash = _repository.GetUserPasswordHash(username);
isPasswordValid = simpleHash.Verify("Password123", storedHash);

Use:

git remote prune <remote>

Where <remote> is a remote source name like origin or upstream.

Example: git remote prune origin

Addition with @cletus answer, You have to fetch all model fields(upper hierarchy) and set field.setAccessible(true) to access private members. Here is the full snippet:

@Override
public String toString() {
    StringBuilder result = new StringBuilder();
    String newLine = System.getProperty("line.separator");

    result.append(getClass().getSimpleName());
    result.append( " {" );
    result.append(newLine);

    List<Field> fields = getAllModelFields(getClass());

    for (Field field : fields) {
        result.append("  ");
        try {
            result.append(field.getName());
            result.append(": ");
            field.setAccessible(true);
            result.append(field.get(this));

        } catch ( IllegalAccessException ex ) {
//                System.err.println(ex);
        }
        result.append(newLine);
    }
    result.append("}");
    result.append(newLine);

    return result.toString();
}

private List<Field> getAllModelFields(Class aClass) {
    List<Field> fields = new ArrayList<>();
    do {
        Collections.addAll(fields, aClass.getDeclaredFields());
        aClass = aClass.getSuperclass();
    } while (aClass != null);
    return fields;
}

As @nasreddine answered or you can use /d

cd /d d:\Docs\Java

For more help on the cd command use:

C:\Documents and Settings\kenny>help cd

Displays the name of or changes the current directory.

CHDIR [/D] [drive:][path] CHDIR [..] CD [/D] [drive:][path] CD [..]

.. Specifies that you want to change to the parent directory.

Type CD drive: to display the current directory in the specified drive. Type CD without parameters to display the current drive and directory.

Use the /D switch to change current drive in addition to changing current directory for a drive.

If Command Extensions are enabled CHDIR changes as follows:

The current directory string is converted to use the same case as the on disk names. So CD C:\TEMP would actually set the current directory to C:\Temp if that is the case on disk.

CHDIR command does not treat spaces as delimiters, so it is possible to CD into a subdirectory name that contains a space without surrounding the name with quotes. For example:

cd \winnt\profiles\username\programs\start menu

is the same as:

cd "\winnt\profiles\username\programs\start menu"

which is what you would have to type if extensions were disabled.

Maybe you're looking for this, a code that receive your javascript object, create a FormData object from it and then POST it to your server using new Fetch API:

    let myJsObj = {'someIndex': 'a value'};

    let datos = new FormData();
    for (let i in myJsObj){
        datos.append( i, myJsObj[i] );
    }

    fetch('your.php', {
        method: 'POST',
        body: datos
    }).then(response => response.json())
        .then(objson => {
            console.log('Success:', objson);
        })
        .catch((error) => {
            console.error('Error:', error);
        });

I was using Write #1 "Print my Line" instead I tried Print #1, "Print my Line" and it give me all the data without default Quote(")

Dim strFile_Path As String
strFile_Path = ThisWorkbook.Path & "\" & "XXXX" & VBA.Format(VBA.Now, "dd-MMM-yyyy hh-mm") & ".txt"
Open strFile_Path For Output As #1

Dim selectedFeature As String

For counter = 7 To maxNumberOfColumn

        selectedFeature = "X"
        Print #1, selectedFeature
        'Write #1, selectedFeature

Next counter
Close #1

a.button a:hover means "a link that's being hovered over that is a child of a link with the class button".

Go instead for a.button:hover.

The selected answer is almost perfect, but depending on the space, items width can be not equal. (In my case it was critical). So i've ended up with this code which increases space a little bit, so items are all the same width.

   class GridSpacingItemDecoration(private val columnCount: Int, @Px preferredSpace: Int, private val includeEdge: Boolean): RecyclerView.ItemDecoration() {

    /**
     * In this algorithm space should divide by 3 without remnant or width of items can have a difference
     * and we want them to be exactly the same
     */
    private val space = if (preferredSpace % 3 == 0) preferredSpace else (preferredSpace + (3 - preferredSpace % 3))

    override fun getItemOffsets(outRect: Rect, view: View, parent: RecyclerView, state: RecyclerView.State?) {
        val position = parent.getChildAdapterPosition(view)

        if (includeEdge) {

            when {
                position % columnCount == 0 -> {
                    outRect.left = space
                    outRect.right = space / 3
                }
                position % columnCount == columnCount - 1 -> {
                    outRect.right = space
                    outRect.left = space / 3
                }
                else -> {
                    outRect.left = space * 2 / 3
                    outRect.right = space * 2 / 3
                }
            }

            if (position < columnCount) {
                outRect.top = space
            }

            outRect.bottom = space

        } else {

            when {
                position % columnCount == 0 -> outRect.right = space * 2 / 3
                position % columnCount == columnCount - 1 -> outRect.left = space * 2 / 3
                else -> {
                    outRect.left = space / 3
                    outRect.right = space / 3
                }
            }

            if (position >= columnCount) {
                outRect.top = space
            }
        }
    }

}

Actually, the simplest thing (in GNU sed, at least) is to use a different separator for the sed substitution (s) command. So, instead of s/pattern/'$mypath'/ being expanded to s/pattern//my/path/, which will of course confuse the s command, use s!pattern!'$mypath'!, which will be expanded to s!pattern!/my/path!. I’ve used the bang (!) character (or use anything you like) which avoids the usual, but-by-no-means-your-only-choice forward slash as the separator.

There is a good solution to this issue:

import com.fasterxml.jackson.databind.ObjectMapper;

ObjectMapper objectMapper = new ObjectMapper();

***DTO premierDriverInfoDTO = objectMapper.convertValue(jsonString, ***DTO.class); 

Map<String, String> map = objectMapper.convertValue(jsonString, Map.class);

Why did this issue occur? I guess you didn't specify the specific type when converting a string to the object, which is a class with a generic type, such as, User <T>.

Maybe there is another way to solve it, using Gson instead of ObjectMapper. (or see here Deserializing Generic Types with GSON)

Gson gson = new GsonBuilder().create();

Type type = new TypeToken<BaseResponseDTO<List<PaymentSummaryDTO>>>(){}.getType();

BaseResponseDTO<List<PaymentSummaryDTO>> results = gson.fromJson(jsonString, type);

BigDecimal revenue = results.getResult().get(0).getRevenue();

In Sender Activity Side:

Intent passIntent = new Intent(getApplicationContext(), "ActivityName".class);
passIntent.putExtra("value", integerValue);
startActivity(passIntent);

In Receiver Activity Side:

int receiveValue = getIntent().getIntExtra("value", 0);

First, you need to create your branch locally

git checkout -b your_branch

After that, you can work locally in your branch, when you are ready to share the branch, push it. The next command push the branch to the remote repository origin and tracks it

git push -u origin your_branch

Your Teammates/colleagues can push to your branch by doing commits and then push explicitly

... work ...
git commit
... work ...
git commit
git push origin HEAD:refs/heads/your_branch 

avoiding the top and bottom margin will solve your problem

@media print {
     @page {
        margin-left: 0.5in;
        margin-right: 0.5in;
        margin-top: 0;
        margin-bottom: 0;
      }
}

You can use the ui object provided to the events, specifically you want the stop event, the ui.item property and .index(), like this:

$("#sortable").sortable({
    stop: function(event, ui) {
        alert("New position: " + ui.item.index());
    }
});

You can see a working demo here, remember the .index() value is zero-based, so you may want to +1 for display purposes.

Using fairly simple code:

int i;
int value;
int n;
char ch;

/* Skip i==0 because that will be the program name */
for (i=1; i<argc; i++) {
    n = sscanf(argv[i], "%d%c", &value, &ch);

    if (n != 1) {
        /* sscanf didn't find a number to convert, so it wasn't a number */
    }
    else {
        /* It was */
    }
}

This solution uses one function to split milliseconds into a parts object, and another function to format the parts object.

I created 2 format functions, one as you requested, and another that prints a friendly string and considering singular/plural, and includes an option to show milliseconds.

function parseDuration(duration) {_x000D_
  let remain = duration_x000D_

If you have a lot of binary data to read, you might want to consider the struct module. It is documented as converting "between C and Python types", but of course, bytes are bytes, and whether those were created as C types does not matter. For example, if your binary data contains two 2-byte integers and one 4-byte integer, you can read them as follows (example taken from struct documentation):

>>> struct.unpack('hhl', b'\x00\x01\x00\x02\x00\x00\x00\x03')
(1, 2, 3)

You might find this more convenient, faster, or both, than explicitly looping over the content of a file.

The problem is that in IE (which is what I presume you're testing in), the <iframe> element has a document property that refers to the document containing the iframe, and this is getting used before the contentDocument or contentWindow.document properties. What you need is:

function GetDoc(x) {
    return x.contentDocument || x.contentWindow.document;
}

Also, document.all is not available in all browsers and is non-standard. Use document.getElementById() instead.

Use this I think it's better

   *isAngularSite(false);*
    browser.get(crmUrl);


    login.username.sendKeys(username);
    login.password.sendKeys(password);
    login.submit.click();

    *isAngularSite(true);*

For you to use this setting of isAngularSite should put this in your protractor.conf.js here:

        global.isAngularSite = function(flag) {
        browser.ignoreSynchronization = !flag;
        };

Aligning text in native markdown is not possible. However, you can align the text using inline HTML tags.

<div style="text-align: right"> your-text-here </div>

To justify, replace right with justify in the above.

I was having this problem because I was trying to connect to MySQL but I didn't have the required package. I figured it out because of @Amadan's comment to check the error log. In my case, I was having the error: Call to undefined function mysql_connect()

If your PHP file has any code to connect with a My-SQL db then you might need to install php5-mysql first. I was getting this error because I hadn't installed it. All my file permissions were good. In Ubuntu, you can install it by the following command:

sudo apt-get install php5-mysql

DON'T be tempted to do things like this:

Select * from [User] U where convert(varchar(10),U.DateCreated, 120) = '2014-02-07'

This is a better way:

Select * from [User] U 
where U.DateCreated >= '2014-02-07' and U.DateCreated < dateadd(day,1,'2014-02-07')

see: What does the word “SARGable” really mean?

EDIT + There are 2 fundamental reasons for avoiding use of functions on data in the where clause (or in join conditions).

1. In most cases using a function on data to filter or join removes the ability of the optimizer to access an index on that field, hence making the query slower (or more "costly")
2. The other is, for every row of data involved there is at least one calculation being performed. That could be adding hundreds, thousands or many millions of calculations to the query so that we can compare to a single criteria like 2014-02-07. It is far more efficient to alter the criteria to suit the data instead.

"Amending the criteria to suit the data" is my way of describing "use SARGABLE predicates"

And do not use between either.

the best practice with date and time ranges is to avoid BETWEEN and to always use the form:

WHERE col >= '20120101' AND col < '20120201' This form works with all types and all precisions, regardless of whether the time part is applicable.

http://sqlmag.com/t-sql/t-sql-best-practices-part-2 (Itzik Ben-Gan)

The C++ specification itself (old version but good enough for this) leaves this open.

There are four signed integer types: 'signed char', 'short int', 'int', and 'long int'. In this list, each type provides at least as much storage as those preceding it in the list. Plain ints have the natural size suggested by the architecture of the execution environment* ;

[Footnote: that is, large enough to contain any value in the range of INT_MIN and INT_MAX, as defined in the header <climits>. --- end foonote]

Try this, it worked for me!

If you happen to have Eclipse not responding anymore sometimes, the reason could be that you sit on a 64bit machine where eclipse needs more memory. Be sure to have (at least) the following configurations in your eclipse.ini (I even use bigger values for the PermSizes):

-Xms512m
-Xmx1024m
-XX:PermSize=64m
-XX:MaxPermSize=128m

I have to agree with foobarbecue (I don't have enough recs to be able to simply insert a comment under his post):

It's now recommended that python notebook isn't started wit the argument --pylab, and according to Fernando Perez (creator of ipythonnb) %matplotlib inline should be the initial notebook command.

More specific:

$("#id1 p:contains('dog')").text($("#id1 p:contains('dog')").text().replace('dog', 'doll'));

In order to have Click Listener, DoubleClick Listener, OnLongPress Listener, Swipe Left, Swipe Right, Swipe Up, Swipe Down on Single View you need to setOnTouchListener. i.e,

view.setOnTouchListener(new OnSwipeTouchListener(MainActivity.this) {

            @Override
            public void onClick() {
                super.onClick();
                // your on click here
            }

            @Override
            public void onDoubleClick() {
                super.onDoubleClick();
                // your on onDoubleClick here
            }

            @Override
            public void onLongClick() {
                super.onLongClick();
                // your on onLongClick here
            }

            @Override
            public void onSwipeUp() {
                super.onSwipeUp();
                // your swipe up here
            }

            @Override
            public void onSwipeDown() {
                super.onSwipeDown();
                // your swipe down here.
            }

            @Override
            public void onSwipeLeft() {
                super.onSwipeLeft();
                // your swipe left here.
            }

            @Override
            public void onSwipeRight() {
                super.onSwipeRight();
                // your swipe right here.
            }
        });

}

For this you need OnSwipeTouchListener class that implements OnTouchListener.

public class OnSwipeTouchListener implements View.OnTouchListener {

private GestureDetector gestureDetector;

public OnSwipeTouchListener(Context c) {
    gestureDetector = new GestureDetector(c, new GestureListener());
}

public boolean onTouch(final View view, final MotionEvent motionEvent) {
    return gestureDetector.onTouchEvent(motionEvent);
}

private final class GestureListener extends GestureDetector.SimpleOnGestureListener {

    private static final int SWIPE_THRESHOLD = 100;
    private static final int SWIPE_VELOCITY_THRESHOLD = 100;

    @Override
    public boolean onDown(MotionEvent e) {
        return true;
    }

    @Override
    public boolean onSingleTapUp(MotionEvent e) {
        onClick();
        return super.onSingleTapUp(e);
    }

    @Override
    public boolean onDoubleTap(MotionEvent e) {
        onDoubleClick();
        return super.onDoubleTap(e);
    }

    @Override
    public void onLongPress(MotionEvent e) {
        onLongClick();
        super.onLongPress(e);
    }

    // Determines the fling velocity and then fires the appropriate swipe event accordingly
    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
        boolean result = false;
        try {
            float diffY = e2.getY() - e1.getY();
            float diffX = e2.getX() - e1.getX();
            if (Math.abs(diffX) > Math.abs(diffY)) {
                if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffX > 0) {
                        onSwipeRight();
                    } else {
                        onSwipeLeft();
                    }
                }
            } else {
                if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffY > 0) {
                        onSwipeDown();
                    } else {
                        onSwipeUp();
                    }
                }
            }
        } catch (Exception exception) {
            exception.printStackTrace();
        }
        return result;
    }
}

public void onSwipeRight() {
}

public void onSwipeLeft() {
}

public void onSwipeUp() {
}

public void onSwipeDown() {
}

public void onClick() {

}

public void onDoubleClick() {

}

public void onLongClick() {

}
}

just my couple cents... the practice that I often use is to organize the methods like this as a custom helper

public static class StreamHelpers
{
    public static byte[] ReadFully(this Stream input)
    {
        using (MemoryStream ms = new MemoryStream())
        {
            input.CopyTo(ms);
            return ms.ToArray();
        }
    }
}

add namespace to the config file and use it anywhere you wish

If you have date object like

var date = new Date('2017/12/03');

then there is inbuilt method in javascript for getting date in milliseconds format which is valueOf()

date.valueOf(); //1512239400000 in milliseconds format

I had to add the files item to the tsconfig.json file, like so:

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "sourceMap": true,
    },
    "files": [
        "../MyFile.ts"
    ] 
}

More details here: https://www.typescriptlang.org/docs/handbook/tsconfig-json.html

A brute force change can be applied. This will work to change, but it's a longer process.

Go to the app folder src/app

1. Open this file: app.component.ts

2. Change this code styleUrls: ['./app.component.css'] to styleUrls: ['./app.component.scss']

3. Save and close.

In the same folder src/app

1. Rename the extension for the app.component.css file to (app.component.scss)

2. Follow this change for all the other components. (ex. home, about, contact, etc...)

The angular.json configuration file is next. It's located at the project root.

1. Search and Replace the css change it to (scss).

2. Save and close.

Lastly, Restart your ng serve -o.

If the compiler complains at you, go over the steps again.

Make sure to follow the steps in app/src closely.

This works like a charm, fast and accurate:

function replace_string_in_file($filename, $string_to_replace, $replace_with){
    $content=file_get_contents($filename);
    $content_chunks=explode($string_to_replace, $content);
    $content=implode($replace_with, $content_chunks);
    file_put_contents($filename, $content);
}

Usage:

$filename="users/data/letter.txt";
$string_to_replace="US$";
$replace_with="Yuan";
replace_string_in_file($filename, $string_to_replace, $replace_with);

// never forget about EXPLODE when it comes about string parsing // it's a powerful and fast tool

Use the start command with the /b flag to run a command/application without opening a new window. For example, this runs dotnet run in the background:

start /b dotnet run

You can pass parameters to the command/application too. For example, I'm starting 3 instances of this C# project, with parameter values of x, y, and z:

To stop the program(s) running in the background: CTRL + BREAK

In my experience, this stops all of the background commands/programs you have started in that cmd instance.

According to the Microsoft docs:

CTRL+C handling is ignored unless the application enables CTRL+C processing. Use CTRL+BREAK to interrupt the application.

Key differences between Serializable and Externalizable

1. Marker interface: Serializable is marker interface without any methods. Externalizable interface contains two methods: writeExternal() and readExternal().
2. Serialization process: Default Serialization process will be kicked-in for classes implementing Serializable interface. Programmer defined Serialization process will be kicked-in for classes implementing Externalizable interface.
3. Maintenance: Incompatible changes may break serialisation.
4. Backward Compatibility and Control: If you have to support multiple versions, you can have full control with Externalizable interface. You can support different versions of your object. If you implement Externalizable, it's your responsibility to serialize super class
5. public No-arg constructor: Serializable uses reflection to construct object and does not require no arg constructor. But Externalizable demands public no-arg constructor.

Refer to blog by Hitesh Garg for more details.

use the xclip which is command line interface to X selections

install

apt-get install xclip

usage

echo "test xclip " > /tmp/test.xclip
xclip -i < /tmp/test.xclip
xclip -o > /tmp/test.xclip.out

cat /tmp/test.xclip.out   # "test xclip"

enjoy.

Updated Answer: Up Navigation Design

You have to declare which activity is the appropriate parent for each activity. Doing so allows the system to facilitate navigation patterns such as Up because the system can determine the logical parent activity from the manifest file.

So for that you have to declare your parent Activity in tag Activity with attribute

android:parentActivityName

Like,

<!-- The main/home activity (it has no parent activity) -->
    <activity
        android:name="com.example.app_name.A" ...>
        ...
    </activity>
    <!-- A child of the main activity -->
    <activity
        android:name=".B"
        android:label="B"
        android:parentActivityName="com.example.app_name.A" >
        <!-- Parent activity meta-data to support 4.0 and lower -->
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.example.app_name.A" />
    </activity>

With the parent activity declared this way, you can navigate Up to the appropriate parent like below,

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    // Respond to the action bar's Up/Home button
    case android.R.id.home:
        NavUtils.navigateUpFromSameTask(this);
        return true;
    }
    return super.onOptionsItemSelected(item);
}

So When you call NavUtils.navigateUpFromSameTask(this); this method, it finishes the current activity and starts (or resumes) the appropriate parent activity. If the target parent activity is in the task's back stack, it is brought forward as defined by FLAG_ACTIVITY_CLEAR_TOP.

And to display Up button you have to declare setDisplayHomeAsUpEnabled():

@Override
public void onCreate(Bundle savedInstanceState) {
    ...
    getActionBar().setDisplayHomeAsUpEnabled(true);
}

Old Answer: (Without Up Navigation, default Back Navigation)

It happen only if you are starting Activity A again from Activity B.

Using startActivity().

Instead of this from Activity A start Activity B using startActivityForResult() and override onActivtyResult() in Activity A.

Now in Activity B just call finish() on button Up. So now you directed to Activity A's onActivityResult() without creating of Activity A again..

->STRICT_TRANS_TABLES is responsible for setting MySQL strict mode.

->To check whether strict mode is enabled or not run the below sql:

SHOW VARIABLES LIKE 'sql_mode';

If one of the value is STRICT_TRANS_TABLES, then strict mode is enabled, else not. In my case it gave

+--------------+------------------------------------------+ 
|Variable_name |Value                                     |
+--------------+------------------------------------------+
|sql_mode      |STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION|
+--------------+------------------------------------------+

Hence strict mode is enabled in my case as one of the value is STRICT_TRANS_TABLES.

->To disable strict mode run the below sql:

set global sql_mode='';

[or any mode except STRICT_TRANS_TABLES. Ex: set global sql_mode='NO_ENGINE_SUBSTITUTION';]

->To again enable strict mode run the below sql:

set global sql_mode='STRICT_TRANS_TABLES';

My solution for rounding specific corners of UIView and UITextFiels in swift is to use

.layer.cornerRadius

and

layer.maskedCorners

of actual UIView or UITextFields.

Example:

fileprivate func inputTextFieldStyle() {
        inputTextField.layer.masksToBounds = true
        inputTextField.layer.borderWidth = 1
        inputTextField.layer.cornerRadius = 25
        inputTextField.layer.maskedCorners = [.layerMaxXMaxYCorner,.layerMaxXMinYCorner]
        inputTextField.layer.borderColor = UIColor.white.cgColor
    }

And by using

.layerMaxXMaxYCorner

and

.layerMaxXMinYCorner

, I can specify top right and bottom right corner of the UITextField to be rounded.

You can see the result here:

As of Notepad++ 6.9, the new Folder as Workspace feature can be used.

Folder as Workspace opens your folder(s) in a panel so you can browse folder(s) and open any file in Notepad++. Every changement in the folder(s) from outside will be synchronized in the panel. Usage: Simply drop 1 (or more) folder(s) in Notepad++.

This feature has the advantage of not showing your entire file system when just the working directory is needed. It also means you don't need plugins for it to work.

If you have too many installers to find what you are looking for easily, here is some powershell to provide a filter and narrow it down a little by display name.

$filter = "*core*sdk*"; (Get-ChildItem HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall).Name | % { $path = "Registry::$_"; Get-ItemProperty $path } | Where-Object { $_.DisplayName -like $filter } | Select-Object -Property DisplayName, PsChildName

All you wanted (at the time the question was originally asked) was a hint. Here's a hint: In Python, you can use dictionaries.

I don't know why this question was reopened but here is a tidyverse option.

x %>% 
  arrange(desc(value)) %>%
  mutate(variable=fct_reorder(variable,value)) %>% 
ggplot(aes(variable,value,fill=variable)) + geom_bar(stat="identity") + 
  scale_y_continuous("",label=scales::percent) + coord_flip() 

You may pass an object to the data option in $.ajax. jQuery will send this as regular post data, just like a normal HTML form.

$.ajax({
    type: "POST",
    url: "TelephoneNumbers.aspx/DeleteNumber",
    data: dataO, // same as using {numberId: 1, companyId: 531}
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(msg) {
        alert('In Ajax');
    }
});

Maybe jcmd?

Jcmd utility is used to send diagnostic command requests to the JVM, where these requests are useful for controlling Java Flight Recordings, troubleshoot, and diagnose JVM and Java Applications.

The jcmd tool was introduced with Oracle's Java 7 and is particularly useful in troubleshooting issues with JVM applications by using it to identify Java processes' IDs (akin to jps), acquiring heap dumps (akin to jmap), acquiring thread dumps (akin to jstack), viewing virtual machine characteristics such as system properties and command-line flags (akin to jinfo), and acquiring garbage collection statistics (akin to jstat). The jcmd tool has been called "a swiss-army knife for investigating and resolving issues with your JVM application" and a "hidden gem."

Here’s the process you’ll need to use in invoking the jcmd:

1. Go to jcmd <pid> GC.heap_dump <file-path>
2. In which
3. pid: is a Java Process Id, for which the heap dump will be captured Also, the
4. file-path: is a file path in which the heap dump is be printed.

Check it out for more information about taking Java heap dump.

The problem is that you are using the bitwise or operator: |. If you use the logical or operator, ||, your code will work fine.

Difference between & and && in Java?

There is no reason to do that. In fact, I would choose to combine declaration and initialization as in

final Boolean isMatch = email1.equals (email2);

using the final keyword so you can't change it (accidentally) afterwards anymore either.

The setup:

    List<int[]> intArrays=new ArrayList<>();
    int anExample[]={1,2,3};
    intArrays.add(anExample);

To retrieve a single int[] array in the ArrayList by index:

    int[] anIntArray = intArrays.get(0); //'0' is the index
    //iterate the retrieved array an print the individual elements
    for (int aNumber : anIntArray ) { 
        System.out.println("Arraylist contains:" + aNumber );
    }

To retrieve all int[] arrays in the ArrayList:

    //iterate the ArrayList, get and print the elements of each int[] array  
    for(int[] anIntArray:intArrays) {
       //iterate the retrieved array an print the individual elements
       for (int aNumber : anIntArray) {
           System.out.println("Arraylist contains:" + aNumber);
       }
}

Output formatting can be performed based on this logic. Goodluck!!

After I set core.autocrlf=true I was getting "LF will be replaced by CRLF" (note not "CRLF will be replaced by LF") when I was git adding (or perhaps it was it on git commit?) edited files in windows on a repository (that does use LF) that was checked out before I set core.autocrlf=true.

I made a new checkout with core.autocrlf=true and now I'm not getting those messages.

After wrestling with this problem today my opinion is this: BEGIN...END brackets code just like {....} does in C languages, e.g. code blocks for if...else and loops

GO is (must be) used when succeeding statements rely on an object defined by a previous statement. USE database is a good example above, but the following will also bite you:

alter table foo add bar varchar(8);
-- if you don't put GO here then the following line will error as it doesn't know what bar is.
update foo set bar = 'bacon';
-- need a GO here to tell the interpreter to execute this statement, otherwise the Parser will lump it together with all successive statements.

It seems to me the problem is this: the SQL Server SQL Parser, unlike the Oracle one, is unable to realise that you're defining a new symbol on the first line and that it's ok to reference in the following lines. It doesn't "see" the symbol until it encounters a GO token which tells it to execute the preceding SQL since the last GO, at which point the symbol is applied to the database and becomes visible to the parser.

Why it doesn't just treat the semi-colon as a semantic break and apply statements individually I don't know and wish it would. Only bonus I can see is that you can put a print() statement just before the GO and if any of the statements fail the print won't execute. Lot of trouble for a minor gain though.

before you do other way, please do open php.exe on your PHP folder. run it and if you faced any error statement on it, you can fix it manually. else, do most-usefull post in this thread.

The ready event is always execute at the only html page is loaded to the browser and the functions are executed....

To populate a List of String, you need not use custom row mapper. Implement it using queryForList.

List<String>data=jdbcTemplate.queryForList(query,String.class)

numpy.linspace() gives you a one-dimensional NumPy array. For example:

>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([  1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.])

Therefore:

for index,point in my_array

cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:

>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])

Now you can do this:

>>> for x, y in two_d:
    print(x, y)

1 2
4 5

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

Came across similar scenario and the CASE expression was useful to me.

UPDATE reports SET is_default = 
case 
 when report_id = 123 then true
 when report_id != 123 then false

WHERE account_id = 321;

Reports - is a table here, account_id is same for the report_ids mentioned above. The above query will set 1 record (the one which matches the condition) to true and all the non-matching ones to false.

You can simply design an xml interface for your progressbar and pass it as a view to a AlertDialog, then show or dismiss the dialog anytime you want.

progress.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:padding="13dp"
    android:layout_centerHorizontal="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <ProgressBar
        android:id="@+id/loader"
        android:layout_marginEnd="5dp"
        android:layout_width="45dp"
        android:layout_height="45dp" />
    <TextView
        android:layout_width="wrap_content"
        android:text="Loading..."
        android:textAppearance="?android:textAppearanceSmall"
        android:layout_gravity="center_vertical"
        android:id="@+id/loading_msg"
        android:layout_toEndOf="@+id/loader"
        android:layout_height="wrap_content" />

</LinearLayout>

The code code that displays the progress dialog. Just copy this code and paste it your fragment.

  AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
       private void setDialog(boolean show){
            builder.setView(R.layout.progress);
            Dialog dialog = builder.create();
            if (show)dialog.show();
            else dialog.dismiss();
        }

Then just call the method whenever you want to show the progressdialog and pass true as an argument to show it or false to dismiss the dialog.

lines = open(filename).read().splitlines()

They are slightly different - the ETag does not have any information that the client can use to determine whether or not to make a request for that file again in the future. If ETag is all it has, it will always have to make a request. However, when the server reads the ETag from the client request, the server can then determine whether to send the file (HTTP 200) or tell the client to just use their local copy (HTTP 304). An ETag is basically just a checksum for a file that semantically changes when the content of the file changes.

The Expires header is used by the client (and proxies/caches) to determine whether or not it even needs to make a request to the server at all. The closer you are to the Expires date, the more likely it is the client (or proxy) will make an HTTP request for that file from the server.

So really what you want to do is use BOTH headers - set the Expires header to a reasonable value based on how often the content changes. Then configure ETags to be sent so that when clients DO send a request to the server, it can more easily determine whether or not to send the file back.

One last note about ETag - if you are using a load-balanced server setup with multiple machines running Apache you will probably want to turn off ETag generation. This is because inodes are used as part of the ETag hash algorithm which will be different between the servers. You can configure Apache to not use inodes as part of the calculation but then you'd want to make sure the timestamps on the files are exactly the same, to ensure the same ETag gets generated for all servers.

Somewhere, you need to tell Apache that people are allowed to see contents of this directory.

<Directory "F:/bar/public">
    Order Allow,Deny
    Allow from All
    # Any other directory-specific stuff
</Directory>

I know this is old, and using SPL iterator maybe just an overkill, but anyway, another solution here:

$ary = array(1, 2, 3, 4, 'last');
$ary = new ArrayIterator($ary);
$ary = new CachingIterator($ary);
foreach ($ary as $each) {
    if (!$ary->hasNext()) { // we chain ArrayIterator and CachingIterator
                            // just to use this `hasNext()` method to see
                            // if this is the last element
       echo $each;
    }
}

Fun fact!

The 'modulus' operation is defined as:

a % n ==> a - (a/n) * n

Ref:Modular Arithmetic

So you could roll your own, although it will be FAR slower than the built in % operator:

public static int Mod(int a, int n)
{
    return a - (int)((double)a / n) * n;
}

Edit: wow, misspoke rather badly here originally, thanks @joren for catching me

Now here I'm relying on the fact that division + cast-to-int in C# is equivalent to Math.Floor (i.e., it drops the fraction), but a "true" implementation would instead be something like:

public static int Mod(int a, int n)
{
    return a - (int)Math.Floor((double)a / n) * n;
}

In fact, you can see the differences between % and "true modulus" with the following:

var modTest =
    from a in Enumerable.Range(-3, 6)
    from b in Enumerable.Range(-3, 6)
    where b != 0
    let op = (a % b)
    let mod = Mod(a,b)
    let areSame = op == mod
    select new 
    { 
        A = a,
        B = b,
        Operator = op, 
        Mod = mod, 
        Same = areSame
    };
Console.WriteLine("A      B     A%B   Mod(A,B)   Equal?");
Console.WriteLine("-----------------------------------");
foreach (var result in modTest)
{
    Console.WriteLine(
        "{0,-3} | {1,-3} | {2,-5} | {3,-10} | {4,-6}", 
        result.A,
        result.B,
        result.Operator, 
        result.Mod, 
        result.Same);
}

Results:

A      B     A%B   Mod(A,B)   Equal?

In C++,

static const int foo = 42;

is the preferred way to define & use constants. I.e. use this rather than

#define foo 42

because it doesn't subvert the type-safety system.

you can generate any x-digit random number with mt_rand() function. mt_rand() much faster with rand() function syntax : mt_rand() or mt_rand($min , $max).

example : <?php echo mt_rand(); ?>
