Consider the below situation

public class Person{
    public String Name{get; set;}
    public String Email {get; set;}
    public virtual Employer employer {get; set;}
}

public List<EF.Person> GetPerson(){
    using(EF.DbEntities db = new EF.DbEntities()){
       return db.Person.ToList();
    }
}

Now after this method is called, you cannot lazy load the Employer entity anymore. Why? because the db object is disposed. So you have to do Person.Include(x=> x.employer) to force that to be loaded.

There are two type of paths: absolute and relative. This is basically the same for files in your hard disc and directories in a URL.

Absolute paths start with a leading slash. They always point to the same location, no matter where you use them:

• /pages/en/faqs/faq-page1.html

Relative paths are the rest (all that do not start with slash). The location they point to depends on where you are using them

• index.html is:
  • /pages/en/faqs/index.html if called from /pages/en/faqs/faq-page1.html
  • /pages/index.html if called from /pages/example.html
  • etc.

There are also two special directory names: . and ..:

• . means "current directory"
• .. means "parent directory"

You can use them to build relative paths:

• ../index.html is /pages/en/index.html if called from /pages/en/faqs/faq-page1.html
• ../../index.html is /pages/index.html if called from /pages/en/faqs/faq-page1.html

Once you're familiar with the terms, it's easy to understand what it's failing and how to fix it. You have two options:

• Use absolute paths
• Fix your relative paths

well, why don't you (get rid of sidebar and) squeeze the table so it is without show/hide effect? It looks odd to me now. The table is too robust.
Otherwise I think scunliffe's suggestion should do it. Or if you wish, you can just set the exact width of table and set either percentage or pixel width for table cells.

You can also get this error if you use special character greek letters like \alpha \beta and so on outside of math mode. After i wrapped them in \(...\) the error was gone.

From mongodb.com:

NoSQL databases differ from older, relational technology in four main areas:

Data models: A NoSQL database lets you build an application without having to define the schema first unlike relational databases which make you define your schema before you can add any data to the system. No predefined schema makes NoSQL databases much easier to update as your data and requirements change.

Data structure: Relational databases were built in an era where data was fairly structured and clearly defined by their relationships. NoSQL databases are designed to handle unstructured data (e.g., texts, social media posts, video, email) which makes up much of the data that exists today.

Scaling: It’s much cheaper to scale a NoSQL database than a relational database because you can add capacity by scaling out over cheap, commodity servers. Relational databases, on the other hand, require a single server to host your entire database. To scale, you need to buy a bigger, more expensive server.

Development model: NoSQL databases are open source whereas relational databases typically are closed source with licensing fees baked into the use of their software. With NoSQL, you can get started on a project without any heavy investments in software fees upfront.

Here:

if(n < 500)
{
    # quit()
    # or 
    # stop("this is some message")
}
else
{
    *insert rest of program here*
}

Both quit() and stop(message) will quit your script. If you are sourcing your script from the R command prompt, then quit() will exit from R as well.

or just study /etc/groups (ok this does probably not work if it uses pam with ldap)

I tried some of the solutions here and they were really helpful. In my experience best solution is to use psql command line, but sometimes i don't feel like using psql command line. So here is another solution for pgAdminIII

create table table1 as(
 select t1.* 
 from dblink(
   'dbname=dbSource user=user1 password=passwordUser1',
   'select * from table1'  
  ) as t1(
    fieldName1 as bigserial,
    fieldName2 as text,
    fieldName3 as double precision 
  )
 )

The problem with this method is that the name of the fields and their types of the table you want to copy must be written.

You are not allowed to use the concatenation operator with the case statement. One possible solution is to use a variable within the process:

process(b0,b1,b2,b3)
   variable bcat : std_logic_vector(0 to 3);
begin
   bcat := b0 & b1 & b2 & b3;
   case bcat is
      when "0000" => x <= 1;
      when others => x <= 2;
   end case;
end process;

Try using this code for v3:

gMap = new google.maps.Map(document.getElementById('map')); 
gMap.setZoom(13);      // This will trigger a zoom_changed on the map
gMap.setCenter(new google.maps.LatLng(37.4419, -122.1419));
gMap.setMapTypeId(google.maps.MapTypeId.ROADMAP);

As OP mention about raw_input - that means he want cli solution. Linux: curses is what you want (windows PDCurses). Curses, is an graphical API for cli software, you can achieve more than just detect key events.

This code will detect keys until new line is pressed.

import curses
import os

def main(win):
    win.nodelay(True)
    key=""
    win.clear()                
    win.addstr("Detected key:")
    while 1:          
        try:                 
           key = win.getkey()         
           win.clear()                
           win.addstr("Detected key:")
           win.addstr(str(key)) 
           if key == os.linesep:
              break           
        except Exception as e:
           # No input   
           pass         

curses.wrapper(main)

Try this

const returnedTarget = Object.assign(target, source);

and pass empty array to target

in case complex objects this way works for me

$.extend(true, [], originalArray) in case of array

$.extend(true, {}, originalObject) in case of object

Take a look at UrlRewriteFilter which is essentially a java-based implementation of Apache's mod_rewrite.

You'll need to extract it into ROOT folder under your Tomcat's webapps folder; you can then configure redirects to any other context within its WEB-INF/urlrewrite.xml configuration file.

Yes, your secret key appears to be missing. Without it, you will not be able to decrypt the files.

Do you have the key backed up somewhere?

Re-creating the keys, whether you use the same passphrase or not, will not work. Each key pair is unique.

A little update on this post: if you are using ktx within your Android project, there is a little helper method that makes updating LayoutParams a lot easier.

If you want to update e.g. only the width you can do that with the following line in Kotlin.

tv.updateLayoutParams { width = WRAP_CONTENT }

Make a datatable with one column instead of List and add strings to the table. You can pass this datatable as structured type and perform another join with title field of your table.

Use like this.

List<String> stockList = new ArrayList<String>();
stockList.add("stock1");
stockList.add("stock2");

String[] stockArr = new String[stockList.size()];
stockArr = stockList.toArray(stockArr);

for(String s : stockArr)
    System.out.println(s);

For those coming across this question more recently, .values is deprecated as of Sequelize 3.0.0. Use .get() instead to get the plain javascript object. So the above code would change to:

var nodedata = node.get({ plain: true });

Breakpoints have seemed to work and not-work on the versions of Eclipse I've used the last couple years. Currently I'm using Juno and just experienced breakpoints-not-working again. The solutions above, although good ones, didn't work in my case.

Here's what worked in my case:

1. deleted the project

2. check it back out from svn

3. import it into Eclipse again

4. run "mvn eclipse:eclipse"

Since the project is also a Groovy/Http-bulder/junit-test project, I had to:

1. convert the project from Java to Groovy

2. add /src/test/groovy to the Java Build Path (Source folders on build path)

3. include "**/*.groovy" on the Java Build Path for /src/test/groovy

You can try using get_the_category():

$categories = get_the_category();
$category_id = $categories[0]->cat_ID;

Here is an extension to the Prototype widget that Jeremy posted on June 4th:

It stops the user from entering more characters if you're using limits in textareas. It checks if there are characters left. If the user copies text into the textarea, the text is cut off at the max. length:

/**
 * Prototype Widget: Textarea
 * Automatically resizes a textarea and displays the number of remaining chars

 */
if (window.Widget == undefined) window.Widget = {}; 

Widget.Textarea = Class.create({
  initialize: function(textarea, options){
    this.textarea = $(textarea);
    this.options = $H({
      'min_height' : 30,
      'max_length' : 400
    }).update(options);

    this.textarea.observe('keyup', this.refresh.bind(this));

    this._shadow = new Element('div').setStyle({
      lineHeight : this.textarea.getStyle('lineHeight'),
      fontSize : this.textarea.getStyle('fontSize'),
      fontFamily : this.textarea.getStyle('fontFamily'),
      position : 'absolute',
      top: '-10000px',
      left: '-10000px',
      width: this.textarea.getWidth() + 'px'
    });
    this.textarea.insert({ after: this._shadow });

    this._remainingCharacters = new Element('p').addClassName('remainingCharacters');
    this.textarea.insert({after: this._remainingCharacters});

Not particularly easily- if you've lost the pointer to the tip of a branch, it's rather like finding a needle in a haystack. You can find all the commits that don't appear to be referenced any more- git fsck --unreachable will do this for you- but that will include commits that you threw away after a git commit --amend, old commits on branches that you rebased etc etc. So seeing all these commits at once is quite likely far too much information to wade through.

So the flippant answer is, don't lose track of things you're interested in. More seriously, the reflogs will hold references to all the commits you've used for the last 60 days or so by default. More importantly, they will give some context about what those commits are.

split is deprecated since it is part of the family of functions which make use of POSIX regular expressions; that entire family is deprecated in favour of the PCRE (preg_*) functions.

If you do not need the regular expression functionality, then explode is a very good choice (and would have been recommended over split even if that were not deprecated), if on the other hand you do need to use regular expressions then the PCRE alternate is simply preg_split.

Make sure JAVA_HOME is set and the path in environment variables reflects the bin directory of JAVA_HOME. Basically, the PATH should be able to find the keytools.exe file in your jdk location.

XAMPP only offers MySQL (Database Server) & Apache (Webserver) in one setup and you can manage them with the xampp starter.

After the successful installation navigate to your xampp folder and execute the xampp-control.exe

Press the start Button at the mysql row.

Now you've successfully started mysql. Now there are 2 different ways to administrate your mysql server and its databases.

But at first you have to set/change the MySQL Root password. Start the Apache server and type localhost or 127.0.0.1 in your browser's address bar. If you haven't deleted anything from the htdocs folder the xampp status page appears. Navigate to security settings and change your mysql root password.

Now, you can browse to your phpmyadmin under http://localhost/phpmyadmin or download a windows mysql client for example navicat lite or mysql workbench. Install it and log in to your mysql server with your new root password.

Go to the method in X.java, and select Open Call Hierarchy from the context menu.

Just as a note, make sure you check if the browser supports the video function, before you try to invoke it:

if($('#movie1')[0].play)
    $('#movie1')[0].play();

That will prevent JavaScript errors on browsers that don't support the video tag.

The accepted answer work when you have a single line string(the email) but if you have a

multiline string, the error will remain.

Please look into this matter:

<!-- start: definition-->
@{
    dynamic item = new System.Dynamic.ExpandoObject();
    item.MultiLineString = @"a multi-line
                             string";
    item.SingleLineString = "a single-line string";
}
<!-- end: definition-->
<a href="#" onclick="Getinfo('@item.MultiLineString')">6/16/2016 2:02:29 AM</a>
<script>
    function Getinfo(text) {
        alert(text);
    }
</script>

Change the single-quote(') to backtick(`) in Getinfo as bellow and error will be fixed:

<a href="#" onclick="Getinfo(`@item.MultiLineString`)">6/16/2016 2:02:29 AM</a>

I really like Werkzeug's interactive debugger. It's similar to Django's debug page, except that you get an interactive shell on every level of the traceback. If you use the django-extensions, you get a runserver_plus managment command which starts the development server and gives you Werkzeug's debugger on exceptions.

Of course, you should only run this locally, as it gives anyone with a browser the rights to execute arbitrary python code in the context of the server.

Yes, you can do

git push https://username:[email protected]/file.git --all

in this case https://username:[email protected]/file.git replace the origin in git push origin --all

To see more options for git push, try git help push

One of the solutions above worked so well I decided to write a complete demonstration program using wxPython. You should be able to run this program like this: python "your file name"

# Click on the window to draw a line.
# The program will tell you if this and the other line intersect.

import wx

class Point:
    def __init__(self, newX, newY):
        self.x = newX
        self.y = newY

app = wx.App()
frame = wx.Frame(None, wx.ID_ANY, "Main")
p1 = Point(90,200)
p2 = Point(150,80)
mp = Point(0,0) # mouse point
highestX = 0


def ccw(A,B,C):
    return (C.y-A.y) * (B.x-A.x) > (B.y-A.y) * (C.x-A.x)

# Return true if line segments AB and CD intersect
def intersect(A,B,C,D):
    return ccw(A,C,D) != ccw(B,C,D) and ccw(A,B,C) != ccw(A,B,D)

def is_intersection(p1, p2, p3, p4):
    return intersect(p1, p2, p3, p4)

def drawIntersection(pc):
    mp2 = Point(highestX, mp.y)
    if is_intersection(p1, p2, mp, mp2):
        pc.DrawText("intersection", 10, 10)
    else:
        pc.DrawText("no intersection", 10, 10)

def do_paint(evt):
    pc = wx.PaintDC(frame)
    pc.DrawLine(p1.x, p1.y, p2.x, p2.y)
    pc.DrawLine(mp.x, mp.y, highestX, mp.y)
    drawIntersection(pc)

def do_left_mouse(evt):
    global mp, highestX
    point = evt.GetPosition()
    mp = Point(point[0], point[1])
    highestX = frame.Size[0]
    frame.Refresh()

frame.Bind(wx.EVT_PAINT, do_paint)
frame.Bind(wx.EVT_LEFT_DOWN, do_left_mouse)
frame.Show()
app.MainLoop()

My problem is multi modules project with base module, app module and feature module. Each module has AndroidManifest of its own, and I implemented build variant for debug and main. So we must sure that "android:name" just declared in Manifest of debug and main only, and do not set it in any of Manifest in child module. Ex: Manifest in main:

 <application
        android:name=".App"/>

Manifest in debug:

<application
        tools:replace="android:name"
        android:name=".DebugApp"
        />

Do not set "android:name" in other Manifest files like this:

<application android:name=".App">

Just define in feature module like this and it will merged fine

<application> 

Try this way:

echo $( 
    cmd1
    cmd2
    ...
)

When you are running a python script on windows in subprocess you should use python in front of the script name. Try:

process = subprocess.Popen("python /the/script.py")

Dictionaries have the advantage of being a generic type, which makes it type safe and a bit faster due to lack of need for boxing. The following comparison table (constructed using the answers found in a similar SO question post) illustrates some of the other reasons that support dictionaries over hash tables (or vice versa).

The term ‘fixed point’ refers to the corresponding manner in which numbers are represented, with a fixed number of digits after, and sometimes before, the decimal point. With floating-point representation, the placement of the decimal point can ‘float’ relative to the significant digits of the number. For example, a fixed-point representation with a uniform decimal point placement convention can represent the numbers 123.45, 1234.56, 12345.67, etc, whereas a floating-point representation could in addition represent 1.234567, 123456.7, 0.00001234567, 1234567000000000, etc.

Unit testing is meant for testing the very basic functionality (the lowest level functions of the application) to be sure that your application building blocks work correctly. There is probably no formal definition of what does that exactly mean, but you should consider other kinds of testing for the bigger functionality -- see Integration testing. The unit testing framework may not be ideal for the purpose.

Following up @Tim Mahy - There's two possible ways to feed SqlBulkCopy: a DataReader or via DataTable. Here the code for DataTable:

DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("Id", typeof(string)));
dt.Columns.Add(new DataColumn("Name", typeof(string)));
foreach (Entry entry in entries)
    dt.Rows.Add(new string[] { entry.Id, entry.Name });

using (SqlBulkCopy bc = new SqlBulkCopy(connection))
{   // the following 3 lines might not be neccessary
    bc.DestinationTableName = "Entries";
    bc.ColumnMappings.Add("Id", "Id");
    bc.ColumnMappings.Add("Name", "Name");

    bc.WriteToServer(dt);
}

You can use bootstrap tooltip. Do not forget to initialize it.

<span class="tooltip-r" data-toggle="tooltip" data-placement="left" title="Explanation">
inside span
</span>

Will be shown text Explanation on the left side.

and run it with js:

$('.tooltip-r').tooltip();

According to the documentation.

If you are running on the TensorFlow or CNTK backends, your code will automatically run on GPU if any available GPU is detected.

You can check what all devices are used by tensorflow by -

from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())

Also as suggested in this answer

import tensorflow as tf
sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

This will print whether your tensorflow is using a CPU or a GPU backend. If you are running this command in jupyter notebook, check out the console from where you have launched the notebook.

If you are sceptic whether you have installed the tensorflow gpu version or not. You can install the gpu version via pip.

pip install tensorflow-gpu

Use UploadStringAsync method:

WebClient webClient = new WebClient();
webClient.UploadStringCompleted += (s, e) =>
{
    if (e.Error != null)
    {
        //handle your error here
    }
    else
    {
        //post was successful, so do what you need to do here
    }
};

webClient.UploadStringAsync(new Uri(yourUri), UriKind.Absolute), "POST", yourParameters);     

You can't pass command line arguments with execfile(). Look at subprocess instead.

Facebook uses Bit.ly's services to shorten links from their site. While pages that have a username turns into "fb.me/<username>", other links associated with Facebook turns into "on.fb.me/*****". To you use the on.fb.me service, just use your Bit.ly account. Note that if you change the default link shortener on your Bit.ly account to j.mp from bit.ly this service won't work.

Go into the mysql data directory and run du -h --max-depth=1 | grep databasename

I've been using this answer to great effect: Get the property, as a string, from an Expression<Func<TModel,TProperty>>

I realize I already answered this question a while back. The only advantage my other answer has is that it works for static properties. I find the syntax in this answer much more useful because you don't have to create a variable of the type you want to reflect.

You can creat the table you want, save it as an image and then use an image map to creat the link (this way you can put the coords of the hole td to make it in to a link).

'category_name'=>'this cat' also works but isn't printed in the WP docs

TL;DR: The answer depends on your implementation. For the pseudo code you posted, it works with negative weights.

Variants of Dijkstra's Algorithm

The key is there are 3 kinds of implementation of Dijkstra's algorithm, but all the answers under this question ignore the differences among these variants.

1. Using a nested for-loop to relax vertices. This is the easiest way to implement Dijkstra's algorithm. The time complexity is O(V^2).
2. Priority-queue/heap based implementation + NO re-entrance allowed, where re-entrance means a relaxed vertex can be pushed into the priority-queue again to be relaxed again later.
3. Priority-queue/heap based implementation + re-entrance allowed.

Version 1 & 2 will fail on graphs with negative weights (if you get the correct answer in such cases, it is just a coincidence), but version 3 still works.

The pseudo code posted under the original problem is the version 3 above, so it works with negative weights.

Here is a good reference from Algorithm (4th edition), which says (and contains the java implementation of version 2 & 3 I mentioned above):

Q. Does Dijkstra's algorithm work with negative weights?

A. Yes and no. There are two shortest paths algorithms known as Dijkstra's algorithm, depending on whether a vertex can be enqueued on the priority queue more than once. When the weights are nonnegative, the two versions coincide (as no vertex will be enqueued more than once). The version implemented in DijkstraSP.java (which allows a vertex to be enqueued more than once) is correct in the presence of negative edge weights (but no negative cycles) but its running time is exponential in the worst case. (We note that DijkstraSP.java throws an exception if the edge-weighted digraph has an edge with a negative weight, so that a programmer is not surprised by this exponential behavior.) If we modify DijkstraSP.java so that a vertex cannot be enqueued more than once (e.g., using a marked[] array to mark those vertices that have been relaxed), then the algorithm is guaranteed to run in E log V time but it may yield incorrect results when there are edges with negative weights.

For more implementation details and the connection of version 3 with Bellman-Ford algorithm, please see this answer from zhihu. It is also my answer (but in Chinese). Currently I don't have time to translate it into English. I really appreciate it if someone could do this and edit this answer on stackoverflow.

In 2020 I use the MoreLinq Pipe method. https://morelinq.github.io/2.3/ref/api/html/M_MoreLinq_MoreEnumerable_Pipe__1.htm

Guzzle implements PSR-7. That means that it will by default store the body of a message in a Stream that uses PHP temp streams. To retrieve all the data, you can use casting operator:

$contents = (string) $response->getBody();

You can also do it with

$contents = $response->getBody()->getContents();

The difference between the two approaches is that getContents returns the remaining contents, so that a second call returns nothing unless you seek the position of the stream with rewind or seek .

$stream = $response->getBody();
$contents = $stream->getContents(); // returns all the contents
$contents = $stream->getContents(); // empty string
$stream->rewind(); // Seek to the beginning
$contents = $stream->getContents(); // returns all the contents

Instead, usings PHP's string casting operations, it will reads all the data from the stream from the beginning until the end is reached.

$contents = (string) $response->getBody(); // returns all the contents
$contents = (string) $response->getBody(); // returns all the contents

Documentation: http://docs.guzzlephp.org/en/latest/psr7.html#responses

A small correction to the original answer - delete also generates significant amounts of redo (as undo is itself protected by redo). This can be seen from autotrace output:

SQL> delete from t1;

10918 rows deleted.

Try the following regex:

var removedText = self.val().replace(/[^0-9]/, '');

This will match every character that is not (^) in the interval 0-9.

There is a simplest and quick way to import a Gradle project into Eclipse. Just download the Gradle plugin for Eclipse from here.
https://marketplace.eclipse.org/content/gradle-integration-eclipse-0

And then from import select Gradle and your project would be imported. Then you have to click on Build Model to run it.

EDIT
Above link for Gradle plugin is no more valid. You can use the link as mentioned in the comment by @vikramvi

https://marketplace.eclipse.org/content/buildship-gradle-integration

Since none of the answers above actually explain what happened, I decided to chime in and bring some more details to this issue.

Yes, the solution is to run the MySQL Upgrade command, as follows: mysql_upgrade -u root -p --force, but what happened?

The root cause for this issue is the corruption of performance_schema, which can be caused by:

• Organic corruption (volumes going kaboom, engine bug, kernel driver issue etc)
• Corruption during mysql Patch (it is not unheard to have this happen during a mysql patch, specially for major version upgrades)
• A simple "drop database performance_schema" will obviously cause this issue, and it will present the same symptoms as if it was corrupted

This issue might have been present on your database even before the patch, but what happened on MySQL 5.7.8 specifically is that the flag show_compatibility_56 changed its default value from being turned ON by default, to OFF. This flag controls how the engine behaves on queries for setting and reading variables (session and global) on various MySQL Versions.

Because MySQL 5.7+ started to read and store these variables on performance_schema instead of on information_schema, this flag was introduced as ON for the first releases to reduce the blast radius of this change and to let users know about the change and get used to it.

OK, but why does the connection fail? Because depending on the driver you are using (and its configuration), it may end up running commands for every new connection initiated to the database (like show variables, for instance). Because one of these commands can try to access a corrupted performance_schema, the whole connection aborts before being fully initiated.

So, in summary, you may (it's impossible to tell now) have had performance_schema either missing or corrupted before patching. The patch to 5.7.8 then forced the engine to read your variables out of performance_schema (instead of information_schema, where it was reading it from because of the flag being turned ON). Since performance_schema was corrupted, the connections are failing.

Running MySQL upgrade is the best approach, despite the downtime. Turning the flag on is one option, but it comes with its own set of implications as it was pointed out on this thread already.

Both should work, but weight the consequences and know your choices :)

const static int newvals[] = {34,2,4,5,6};

std::copy(newvals, newvals+sizeof(newvals)/sizeof(newvals[0]), array);

If you are using Windows command line to print the data, you should use

chcp 65001

This worked for me!

I am not too sure I would go and use an enum as a full fledged class - this is an object oriented language, and one of the most basic tenets of object orientation is that a class should do one thing and do it well.

An enum is doing a pretty good job at being an enum, and a class is doing a good job as a class. Mixing the two I have a feeling will get you into trouble - for example, you can't pass an instance of an enum as a parameter to a method, primarily because you can't create an instance of an enum.

So, even though you might be able to enum.process() does not mean that you should.

An alternative to kubi's answer is to have a look at the .git/config file which shows the local repository configuration:

cat .git/config

I faced a similar problem, trying to test if jQuery is already present on a page, and if not force it's load, and then execute a function. I tried with @David Hellsing workaround, but with no chance for my needs. In fact, the onload instruction was immediately evaluated, and then the $ usage inside this function was not yet possible (yes, the huggly "$ is not a function." ^^).

So, I referred to this article : https://developer.mozilla.org/fr/docs/Web/Events/load and attached a event listener to my script object.

var script = document.createElement('script');
script.type = "text/javascript";
script.addEventListener("load", function(event) {
    console.log("script loaded :)");
    onjqloaded();
});
script.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(script);

For my needs, it works fine now. Hope this can help others :)

You can just create a new branch and switch onto it. Commit your changes then:

git branch dirty
git checkout dirty
// And your commit follows ...

Alternatively, you can also checkout an existing branch (just git checkout <name>). But only, if there are no collisions (the base of all edited files is the same as in your current branch). Otherwise you will get a message.

I encountered this error when "" was added by mistake to my command line arguments when altering properties for "All Configurations". Removing them from RightClickProject->Properties->Configuration Properties->Debugging->Command Arguments allowed it to run in the debugger again.

also, with wmode=opaque and with IE, the Flash gets the keyboard events, but also the html page receives them, so it can't be use for something like embedding a flash game. Very annoying

the best way is to change your route. The default route (defined in your App_Start) sets /Home/Index

routes.MapRoute(
        "Default", // Route name
        "{controller}/{action}/{id}", // URL with parameters*
        new { controller = "Home", action = "Index", 
        id = UrlParameter.Optional }
);

as the default landing page. You can change that to be any route you wish.

routes.MapRoute(
        "Default", // Route name
        "{controller}/{action}/{id}", // URL with parameters*
        new { controller = "Sales", action = "ProjectionReport", 
        id = UrlParameter.Optional }
);

I was reading a lot about this issue and wanted to provide a very quick workaround that helped me.

let style = window.getComputedStyle(document.getElementById('email'))
  if (style && style.backgroundColor !== inputBackgroundNormalState) {
    this.inputAutofilledByBrowser = true
  }

where inputBackgroundNormalState for my template is 'rgb(255, 255, 255)'.

So basically when browsers apply autocomplete they tend to indicate that the input is autofilled by applying a different (annoying) yellow color on the input.

Edit : this works for every browser

Pure modern 2020 CSS only decision, without blurry scaling or non-handy transforming. And with tick! =)

Works nice in Firefox and Chromium-based browsers.

So, you can rule your checkboxes purely ADAPTIVE, just by setting parent block's font-height and it will grow with text!

Creating a virtual environment for Jupyter Notebooks

A minimal Python install is

sudo apt install python3.7 python3.7-venv python3.7-minimal python3.7-distutils python3.7-dev python3.7-gdbm python3-gdbm-dbg python3-pip

Then you can create and use the environment

/usr/bin/python3.7 -m venv test
cd test
source test/bin/activate
pip install jupyter matplotlib seaborn numpy pandas scipy
# install other packages you need with pip/apt
jupyter notebook
deactivate

You can make a kernel for Jupyter with

ipython3 kernel install --user --name=test

Separation of presentation and data drives my commit messages here.

Your commit message should not be hard-wrapped at any character count and instead line breaks should be used to separate thoughts, paragraphs, etc. as part of the data, not the presentation. In this case, the "data" is the message you are trying to get across and the "presentation" is how the user sees that.

I use a single summary line at the top and I try to keep it short but I don't limit myself to an arbitrary number. It would be far better if Git actually provided a way to store summary messages as a separate entity from the message but since it doesn't I have to hack one in and I use the first line break as the delimiter (luckily, many tools support this means of breaking apart the data).

For the message itself newlines indicate something meaningful in the data. A single newline indicates a start/break in a list and a double newline indicates a new thought/idea.

This is a summary line, try to keep it short and end with a line break.
This is a thought, perhaps an explanation of what I have done in human readable format.  It may be complex and long consisting of several sentences that describe my work in essay format.  It is not up to me to decide now (at author time) how the user is going to consume this data.

Two line breaks separate these two thoughts.  The user may be reading this on a phone or a wide screen monitor.  Have you ever tried to read 72 character wrapped text on a device that only displays 60 characters across?  It is a truly painful experience.  Also, the opening sentence of this paragraph (assuming essay style format) should be an intro into the paragraph so if a tool chooses it may want to not auto-wrap and let you just see the start of each paragraph.  Again, it is up to the presentation tool not me (a random author at some point in history) to try to force my particular formatting down everyone else's throat.

Just as an example, here is a list of points:
* Point 1.
* Point 2.
* Point 3.

Here's what it looks like in a viewer that soft wraps the text.

My suspicion is that the author of Git commit message recommendation you linked has never written software that will be consumed by a wide array of end-users on different devices before (i.e., a website) since at this point in the evolution of software/computing it is well known that storing your data with hard-coded presentation information is a bad idea as far as user experience goes.

You want this - enter N and then take N number of elements.I am considering your input case is just like this

5
2 3 6 6 5

have this in this way in python 3.x (for python 2.x use raw_input() instead if input())

Python 3

n = int(input())
arr = input()   # takes the whole line of n numbers
l = list(map(int,arr.split(' '))) # split those numbers with space( becomes ['2','3','6','6','5']) and then map every element into int (becomes [2,3,6,6,5])

Python 2

n = int(raw_input())
arr = raw_input()   # takes the whole line of n numbers
l = list(map(int,arr.split(' '))) # split those numbers with space( becomes ['2','3','6','6','5']) and then map every element into int (becomes [2,3,6,6,5])

For what you are trying to do, instead of PreparedStatement you can use Statement. Your code may be modified as-

String sql = "SELECT column_name from information_schema.columns where table_name='suppliers';";

Statement s  = connection.createStatement();
ResultSet rs = s.executeQuery(sql);

Hope this helps.

today I meet this problem and I found: URL - MDN Web APIs

var url = new URL("http://test.example.com/dir/subdir/file.html#hash");

This return:

Hoping my first contribution helps you !

Because "append" intuitively means "add at the end of the list". If it was called "push", then it would be unclear whether we're adding stuff at the tail or at head of the list.

Set-ExecutionPolicy Unrestricted -Scope CurrentUser

This will set the execution policy for the current user (stored in HKEY_CURRENT_USER) rather than the local machine (HKEY_LOCAL_MACHINE). This is useful if you don't have administrative control over the computer.

1. In the value or values you want to separate, enter the =NA() formula. This will appear that the value is skipped but the preceding and following data points will be joined by the series line.
2. Enter the data you want to skip in the same location as the original (row or column) but add it as a new series. Add the new series to your chart.
3. Format the new data point to match the original series format (color, shape, etc.). It will appear as though the data point was just skipped in the original series but will still show on your chart if you want to label it or add a callout.

To view open ports, use the following command.

firewall-cmd --list-ports

We use the following to see services whose ports are open.

firewall-cmd --list-services

We use the following to see services whose ports are open and see open ports

firewall-cmd --list-all

To add a service to the firewall, we use the following command, in which case the service will use any port to open in the firewall.

firewall-cmd --add-services=ntp 

For this service to be permanently open we use the following command.

firewall-cmd —add-service=ntp --permanent 

To add a port, use the following command

firewall-cmd --add-port=132/tcp  --permanent

To run the firewall must be reloaded using the following command.

firewall-cmd --reload

Here you can find some useful info about cURL & cookies http://docstore.mik.ua/orelly/webprog/pcook/ch11_04.htm .

You can also use this well done method https://github.com/alixaxel/phunction/blob/master/phunction/Net.php#L89 like a function:

function CURL($url, $data = null, $method = 'GET', $cookie = null, $options = null, $retries = 3)
{
    $result = false;

    if ((extension_loaded('curl') === true) && (is_resource($curl = curl_init()) === true))
    {
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_FAILONERROR, true);
        curl_setopt($curl, CURLOPT_AUTOREFERER, true);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

        if (preg_match('~^(?:DELETE|GET|HEAD|OPTIONS|POST|PUT)$~i', $method) > 0)
        {
            if (preg_match('~^(?:HEAD|OPTIONS)$~i', $method) > 0)
            {
                curl_setopt_array($curl, array(CURLOPT_HEADER => true, CURLOPT_NOBODY => true));
            }

            else if (preg_match('~^(?:POST|PUT)$~i', $method) > 0)
            {
                if (is_array($data) === true)
                {
                    foreach (preg_grep('~^@~', $data) as $key => $value)
                    {
                        $data[$key] = sprintf('@%s', rtrim(str_replace('\\', '/', realpath(ltrim($value, '@'))), '/') . (is_dir(ltrim($value, '@')) ? '/' : ''));
                    }

                    if (count($data) != count($data, COUNT_RECURSIVE))
                    {
                        $data = http_build_query($data, '', '&');
                    }
                }

                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            }

            curl_setopt($curl, CURLOPT_CUSTOMREQUEST, strtoupper($method));

            if (isset($cookie) === true)
            {
                curl_setopt_array($curl, array_fill_keys(array(CURLOPT_COOKIEJAR, CURLOPT_COOKIEFILE), strval($cookie)));
            }

            if ((intval(ini_get('safe_mode')) == 0) && (ini_set('open_basedir', null) !== false))
            {
                curl_setopt_array($curl, array(CURLOPT_MAXREDIRS => 5, CURLOPT_FOLLOWLOCATION => true));
            }

            if (is_array($options) === true)
            {
                curl_setopt_array($curl, $options);
            }

            for ($i = 1; $i <= $retries; ++$i)
            {
                $result = curl_exec($curl);

                if (($i == $retries) || ($result !== false))
                {
                    break;
                }

                usleep(pow(2, $i - 2) * 1000000);
            }
        }

        curl_close($curl);
    }

    return $result;
}

And pass this as $cookie parameter:

$cookie_jar = tempnam('/tmp','cookie');

A good example where to subscribe a setInterval(), and use a clearInterval() to stop the forever loop:

function myTimer() {

}

var timer = setInterval(myTimer, 5000);

call this line to stop the loop:

clearInterval(timer);

Working code from my sources:

HTML WORLD

<select name="select_from" disabled>...</select>

JS WORLD

var from = jQuery('select[name=select_from]');

//add disabled
from.attr('disabled', 'disabled');



//remove it
from.removeAttr("disabled");

You can use array_filter to filter out elements of an array based on a callback function. The callback function takes each element of the array as an argument and you simply return false if that element should be removed. This also has the benefit of removing duplicate values since it scans the entire array.

You can use it like this:

$myArray = array('apple', 'orange', 'banana', 'plum', 'banana');
$output = array_filter($myArray, function($value) { return $value !== 'banana'; });
// content of $output after previous line:
// $output = array('apple', 'orange', 'plum');

And if you want to re-index the array, you can pass the result to array_values like this:

$output = array_values($output);

You could also use reduce() like so:

import glob
file_types = ['*.txt', '*.mdown', '*.markdown']
project_files = reduce(lambda list1, list2: list1 + list2, (glob.glob(t) for t in file_types))

this creates a list from glob.glob() for each pattern and reduces them to a single list.

Mad a similar error, easy to fix:

    TypeError Traceback (most recent call last) <ipython-input-2-1eb12bfdc7db> in <module>
  3 mylist = [10,20,30] ----> 4 arr = np.array[(10,20,30)] 5 d = {'a':10, 'b':20, 'c':30} TypeError: 'builtin_function_or_method' object is not subscriptable

but I should have written it as:

arr = np.array([10,20,30])

Very fixable, rookie/dumb mistake.

If the error message is just

"Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.", then grant the login permission for 'NT AUTHORITY\NETWORK SERVICE'

by using

"sp_grantlogin 'NT AUTHORITY\NETWORK SERVICE'" 

else if the error message is like

"Cannot open database "Phaeton.mdf" requested by the login. The login failed. Login failed for user 'NT AUTHORITY\NETWORK SERVICE'."

try using

"EXEC sp_grantdbaccess 'NT AUTHORITY\NETWORK SERVICE'" 

under your "Phaeton" database.

1. Make sure you logged on as an administrator or you have the same access as an administrator.
2. Start->Control Panel->System and Security->Administrative Tools->Task Scheduler
3. Action->Create Basic Task->Type a name and Click Next
4. Follow through the wizard.

Use SQL Server Object Explorer (SSOX) Instead

Unlike the other answers, this approach uses:
- No special commands.
- No complicated configurations.
Just use the SQL Server Object Explorer

It's pretty straightforward...

• From the View menu, open SQL Server Object Explorer.

• Right click on the {YourTableName} table > View Designer

Done.

Think about it from the browser's point of view. For readonly the browser will send in a variable/value pair. For disabled, it won't.

Run this, then look at the URL after you hit submit:

<html>
<form action=foo.html method=get>
<input name=dis type=text disabled value="dis">
<input name=read type=text readonly value="read">
<input name=normal type=text value="normal">
<input type=submit>
</form>
</html>

As mentioned in the excellent answer by janoside, you need to construct the JSON string and set it as a StringEntity.

To construct the JSON string, you can use any library or method you are comfortable with. Jackson library is one easy example:

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.StringEntity;

ObjectMapper mapper = new ObjectMapper();
ObjectNode node = mapper.createObjectNode();
node.put("name", "value"); // repeat as needed
String JSON_STRING = node.toString();
postMethod.setEntity(new StringEntity(JSON_STRING, ContentType.APPLICATION_JSON));

Just a note in case others have the same problem.

I had the same problem and found a different answer. I found that getting the height of a div that's height is determined by its contents needs to be initiated on window.load, or window.scroll not document.ready otherwise i get odd heights/smaller heights, i.e before the images have loaded. I also used outerHeight().

var currentHeight = 0;
$(window).load(function() {
    //get the natural page height -set it in variable above.

    currentHeight = $('#js_content_container').outerHeight();

    console.log("set current height on load = " + currentHeight)
    console.log("content height function (should be 374)  = " + contentHeight());   

});

Well, here's what worked for me:
Copy and paste the entire data folder, not just the content.
I use xampp, and the path to the data is xampp/mysql/data.

Goodluck!

Everytime I install node.js it needs a reboot and then the path is recognized.

If you are developing for devices with API level 19 or higher you can use the built in PrintedPdfDocument: http://developer.android.com/reference/android/print/pdf/PrintedPdfDocument.html

// open a new document
PrintedPdfDocument document = new PrintedPdfDocument(context,
     printAttributes);

// start a page
Page page = document.startPage(0);

// draw something on the page
View content = getContentView();
content.draw(page.getCanvas());

// finish the page
document.finishPage(page);
. . .
// add more pages
. . .
// write the document content
document.writeTo(getOutputStream());

//close the document
document.close();

Both of the previous answers from Matt York and Cyberbolt are right.

Basic idea is here that you want to get some kind of File explorer in Sublime.

Approach:

1) With File -> New Folder -> Click on Desired folder and Hit Open you will get new popup window in sublime which for me is very annoying

2) I use second option which is drag'n'drop from nautilus (a.k.a. Files) window. Simply drag'n'drop your file you want to explore from nautilus to sublime sidebar. That way you stay in the same window and everything is cool.

Don't forget to enable View -> Sidebar -> Show Sidebar and drag'n'drop there from nautilus and of course run it with root privleges. It works like charm

This is not a system font. this font is not supported in other systems. you can use font-face, convert font from this Site or from this

I needed to get the element as a string.

jQuery("#bob").get(0).outerHTML;

Which will give you something like:

<input type="text" id="bob" value="hello world" />

...as a string rather than a DOM element.

You can actually index directly into the Attributes collection (if you are using C# not VB):

foreach (XmlNode xNode in nodeListName)
{
  XmlNode parent = xNode.ParentNode;
  if (parent.Attributes != null
     && parent.Attributes["split"] != null)
  {
     parentSplit = parent.Attributes["split"].Value;
  }
}

torch.Tensor.view()

Simply put, torch.Tensor.view() which is inspired by numpy.ndarray.reshape() or numpy.reshape(), creates a new view of the tensor, as long as the new shape is compatible with the shape of the original tensor.

Let's understand this in detail using a concrete example.

In [43]: t = torch.arange(18) 

In [44]: t 
Out[44]: 
tensor([ 0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11, 12, 13, 14, 15, 16, 17])

With this tensor t of shape (18,), new views can only be created for the following shapes:

(1, 18) or equivalently (1, -1) or (-1, 18)
(2, 9) or equivalently (2, -1) or (-1, 9)
(3, 6) or equivalently (3, -1) or (-1, 6)
(6, 3) or equivalently (6, -1) or (-1, 3)
(9, 2) or equivalently (9, -1) or (-1, 2)
(18, 1) or equivalently (18, -1) or (-1, 1)

As we can already observe from the above shape tuples, the multiplication of the elements of the shape tuple (e.g. 2*9, 3*6 etc.) must always be equal to the total number of elements in the original tensor (18 in our example).

Another thing to observe is that we used a -1 in one of the places in each of the shape tuples. By using a -1, we are being lazy in doing the computation ourselves and rather delegate the task to PyTorch to do calculation of that value for the shape when it creates the new view. One important thing to note is that we can only use a single -1 in the shape tuple. The remaining values should be explicitly supplied by us. Else PyTorch will complain by throwing a RuntimeError:

RuntimeError: only one dimension can be inferred

So, with all of the above mentioned shapes, PyTorch will always return a new view of the original tensor t. This basically means that it just changes the stride information of the tensor for each of the new views that are requested.

Below are some examples illustrating how the strides of the tensors are changed with each new view.

# stride of our original tensor `t`
In [53]: t.stride() 
Out[53]: (1,)

Now, we will see the strides for the new views:

# shape (1, 18)
In [54]: t1 = t.view(1, -1)
# stride tensor `t1` with shape (1, 18)
In [55]: t1.stride() 
Out[55]: (18, 1)

# shape (2, 9)
In [56]: t2 = t.view(2, -1)
# stride of tensor `t2` with shape (2, 9)
In [57]: t2.stride()       
Out[57]: (9, 1)

# shape (3, 6)
In [59]: t3 = t.view(3, -1) 
# stride of tensor `t3` with shape (3, 6)
In [60]: t3.stride() 
Out[60]: (6, 1)

# shape (6, 3)
In [62]: t4 = t.view(6,-1)
# stride of tensor `t4` with shape (6, 3)
In [63]: t4.stride() 
Out[63]: (3, 1)

# shape (9, 2)
In [65]: t5 = t.view(9, -1) 
# stride of tensor `t5` with shape (9, 2)
In [66]: t5.stride()
Out[66]: (2, 1)

# shape (18, 1)
In [68]: t6 = t.view(18, -1)
# stride of tensor `t6` with shape (18, 1)
In [69]: t6.stride()
Out[69]: (1, 1)

So that's the magic of the view() function. It just changes the strides of the (original) tensor for each of the new views, as long as the shape of the new view is compatible with the original shape.

Another interesting thing one might observe from the strides tuples is that the value of the element in the 0^th position is equal to the value of the element in the 1^st position of the shape tuple.

In [74]: t3.shape 
Out[74]: torch.Size([3, 6])
                        |
In [75]: t3.stride()    |
Out[75]: (6, 1)         |
          |_____________|

This is because:

In [76]: t3 
Out[76]: 
tensor([[ 0,  1,  2,  3,  4,  5],
        [ 6,  7,  8,  9, 10, 11],
        [12, 13, 14, 15, 16, 17]])

the stride (6, 1) says that to go from one element to the next element along the 0^th dimension, we have to jump or take 6 steps. (i.e. to go from 0 to 6, one has to take 6 steps.) But to go from one element to the next element in the 1^st dimension, we just need only one step (for e.g. to go from 2 to 3).

Thus, the strides information is at the heart of how the elements are accessed from memory for performing the computation.

torch.reshape()

This function would return a view and is exactly the same as using torch.Tensor.view() as long as the new shape is compatible with the shape of the original tensor. Otherwise, it will return a copy.

However, the notes of torch.reshape() warns that:

contiguous inputs and inputs with compatible strides can be reshaped without copying, but one should not depend on the copying vs. viewing behavior.

Your encoded text is [B@6499375d. That is not Base64, something went wrong while encoding. That decoding code looks good.

Use this code to convert the byte[] to a String before adding it to the URL:

String encodedEmailString = new String(encodedEmail, "UTF-8");
// ...
String confirmLink = "Complete your registration by clicking on following"
    + "\n<a href='" + confirmationURL + encodedEmailString + "'>link</a>";

The Control class has HorizontalContentAlignment and VerticalContentAlignment properties. These properties determine how a control’s content fills the space within the control.
Set HorizontalContentAlignment and VerticalContentAlignment to Center.

You can do yes | cp -rf xxx yyy, but my gutfeeling says that if you do it as root - your .bashrc or .profile has an alias of cp to cp -i, most modern systems (primarily RH-derivatives) do that to root profiles.

You can check existing aliases by running alias at the command prompt, or which cp to check aliases only for cp.

If you do have an alias defined, running unalias cp will abolish that for the current session, otherwise you can just remove it from your shell profile.

You can temporarily bypass an alias and use the non-aliased version of a command by prefixing it with \, e.g. \cp whatever

Managing XSS requires multiple validations, data from the client side.

1. Input Validations (form validation) on the Server side. There are multiple ways of going about it. You can try JSR 303 bean validation(hibernate validator), or ESAPI Input Validation framework. Though I've not tried it myself (yet), there is an annotation that checks for safe html (@SafeHtml). You could in fact use Hibernate validator with Spring MVC for bean validations -> Ref
2. Escaping URL requests - For all your HTTP requests, use some sort of XSS filter. I've used the following for our web app and it takes care of cleaning up the HTTP URL request - http://www.servletsuite.com/servlets/xssflt.htm
3. Escaping data/html returned to the client (look above at @BalusC explanation).

Try This :

--Default Instance

SQLCMD -S SERVERNAME -E

--OR
--Named Instance

SQLCMD -S SERVERNAME\INSTANCENAME -E

--OR

SQLCMD -S SERVERNAME\INSTANCENAME,1919 -E

In DBeaver you can use parameters in queries just like you can from code, so this will work:

SELECT *
FROM somewhere
WHERE something = :myvar

When you run the query DBeaver will ask you for the value for :myvar and run the query.

If the above doesn't help you - check your module .iml file and see if it contains any errors. (for the app module it will be app.iml).

Jon, a lot of opinion has been given that didn't correctly answer your question.

I will give MY OPINION and then tell you how to do exactly what you asked for.

I see no reason why an assembly couldn't have its own config file. Why is the first level of atomicy (is that a real word?) be at the application level? Why not at the solution level? It's an arbitrary, best-guess decision and as such, an OPINION. If you were to write a logging library and wanted to include a configuration file for it, that would be used globally, why couldn't you hook into the built-in settings functionality? We've all done it ... tried to provide "powerful" functionality to other developers. How? By making assumptions that inherently translated to restrictions. That's exactly what MS did with the settings framework, so you do have to "fool it" a little.

To directly answer your question, simply add the configuration file manually (xml) and name it to match your library and to include the "config" extension. Example:

MyDomain.Mylibrary.dll.Config

Next, use the ConfigurationManager to load the file and access settings:

string assemblyPath = new Uri(Assembly.GetExecutingAssembly().CodeBase).AbsolutePath;
Configuration cfg = ConfigurationManager.OpenExeConfiguration(assemblyPath);
string result = cfg.AppSettings.Settings["TEST_SETTING"].Value;

Note that this fully supports the machine.config heierarchy, even though you've explicitly chosen the app config file. In other words, if the setting isn't there, it will resolve higher. Settings will also override machine.config entries.

Apart from the excellent explanation by Mrry, where he suggested to use device_lib.list_local_devices() I can show you how you can check for GPU related information from the command line.

Because currently only Nvidia's gpus work for NN frameworks, the answer covers only them. Nvidia has a page where they document how you can use the /proc filesystem interface to obtain run-time information about the driver, any installed NVIDIA graphics cards, and the AGP status.

/proc/driver/nvidia/gpus/0..N/information

Provide information about each of the installed NVIDIA graphics adapters (model name, IRQ, BIOS version, Bus Type). Note that the BIOS version is only available while X is running.

So you can run this from command line cat /proc/driver/nvidia/gpus/0/information and see information about your first GPU. It is easy to run this from python and also you can check second, third, fourth GPU till it will fail.

Definitely Mrry's answer is more robust and I am not sure whether my answer will work on non-linux machine, but that Nvidia's page provide other interesting information, which not many people know about.

By default, the classes in the csv module use Windows-style line terminators (\r\n) rather than Unix-style (\n). Could this be what’s causing the apparent double line breaks?

If so, you can override it in the DictWriter constructor:

output = csv.DictWriter(open('file3.csv','w'), delimiter=',', lineterminator='\n', fieldnames=headers)

If it's inside a closure, i'm pretty sure you can't.

Otherwise you just do functionName(); and hit return.

I used the Sebastien Horin function getIp and request()->ip() (at global request), because to localhost the getIp function return null:

$this->getIp() ?? request()->ip();

The getIp function:

public function getIp(){
foreach (array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR') as $key){
    if (array_key_exists($key, $_SERVER) === true){
        foreach (explode(',', $_SERVER[$key]) as $ip){
            $ip = trim($ip); // just to be safe
            if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false){
                return $ip;
            }
        }
    }
}

}

source <(curl -s http://mywebsite.com/myscript.txt)

ought to do it. Alternately, leave off the initial redirection on yours, which is redirecting standard input; bash takes a filename to execute just fine without redirection, and <(command) syntax provides a path.

bash <(curl -s http://mywebsite.com/myscript.txt)

It may be clearer if you look at the output of echo <(cat /dev/null)

As of SQL 2014, this can be accomplished via inline index creation:

CREATE TABLE MyTable(
    a int NOT NULL
    ,b smallint NOT NULL
    ,c smallint NOT NULL
    ,d smallint NOT NULL
    ,e smallint NOT NULL

    -- This creates a primary key
    ,CONSTRAINT PK_MyTable PRIMARY KEY CLUSTERED (a)

    -- This creates a unique nonclustered index on columns b and c
    ,CONSTRAINT IX_MyTable1 UNIQUE (b, c)

    -- This creates a standard non-clustered index on (d, e)
    ,INDEX IX_MyTable4 NONCLUSTERED (d, e)
);
GO

Prior to SQL 2014, CREATE/ALTER TABLE only accepted CONSTRAINTs to be added, not indexes. The fact that primary key and unique constraints are implemented in terms of an index is a side effect.

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

You can use Date.getTime() function, or the Date object itself which when divided returns the time in milliseconds.

var d = new Date();

d/1000

I think your problem is that the margin should be specified in the border tag and not in the grid.

I recently found out that :active:focus does the same thing in css as :active:hover if you need to override a custom css library, they might use both.

When you're serving an .ico file to be used as a favicon, it doesn't matter. All major browsers recognize both mime types correctly. So you could put:

<!-- IE -->
<link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />
<!-- other browsers -->
<link rel="icon" type="image/x-icon" href="favicon.ico" />

or the same with image/vnd.microsoft.icon, and it will work with all browsers.

Note: There is no IANA specification for the MIME-type image/x-icon, so it does appear that it is a little more unofficial than image/vnd.microsoft.icon.

The only case in which there is a difference is if you were trying to use an .ico file in an <img> tag (which is pretty unusual). Based on previous testing, some browsers would only display .ico files as images when they were served with the MIME-type image/x-icon. More recent tests show: Chromium, Firefox and Edge are fine with both content types, IE11 is not. If you can, just avoid using ico files as images, use png.

I faced the same problem due to illegal spaces in my entire code.

I fixed it by selecting one of these spaces and use find and replace to replace all matches with regular spaces.

This worked for me :

npm install -g local-cors-proxy

API endpoint that we want to request that has CORS issues:

https://www.yourdomain.com/test/list

Start Proxy:

lcp --proxyUrl https://www.yourdomain.com

 Proxy Active 

 Proxy Url: http://www.yourdomain.com:28080
 Proxy Partial: proxy
 PORT: 8010

Then in your client code, new API endpoint:

http://localhost:8010/proxy/test/list

End result will be a request to https://www.yourdomain.ie/test/list without the CORS issues!

If your html is similar to the example, so the click event is produced over the label, not in the input, so I use the next code: Html example:

<div id="myButtons" class="btn-group" data-toggle="buttons">
  <label class="btn btn-primary active">
    <input type="radio" name="options" id="option1" autocomplete="off" checked> Radio 1 (preselected)
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option2" autocomplete="off"> Radio 2
  </label>      
</div>

Javascript code for the event:

$('#option1').parent().on("click", function () {
   alert("click fired"); 
});

Add 'justified' class to 'ul'.

<ul class="nav navbar-nav justified">

CSS:

.justified {
    position:absolute;
    left:50%;
}

Now, calculate its 'margin-left' in order to align it to center.

// calculating margin-left to align it to center;
var width = $('.justified').width();
$('.justified').css('margin-left', '-' + (width / 2)+'px');

I had trouble getting the answer back from the dialog box but eventually came up with a solution by combining the answer from this other question display-yes-and-no-buttons-instead-of-ok-and-cancel-in-confirm-box with part of the code from the modal-confirmation dialog

This is what was suggested for the other question:

Create your own confirm box:

<div id="confirmBox">
    <div class="message"></div>
    <span class="yes">Yes</span>
    <span class="no">No</span>
</div>

Create your own confirm() method:

function doConfirm(msg, yesFn, noFn)
{
    var confirmBox = $("#confirmBox");
    confirmBox.find(".message").text(msg);
    confirmBox.find(".yes,.no").unbind().click(function()
    {
        confirmBox.hide();
    });
    confirmBox.find(".yes").click(yesFn);
    confirmBox.find(".no").click(noFn);
    confirmBox.show();
}

Call it by your code:

doConfirm("Are you sure?", function yes()
{
    form.submit();
}, function no()
{
    // do nothing
});

MY CHANGES I have tweaked the above so that instead of calling confirmBox.show() I used confirmBox.dialog({...}) like this

confirmBox.dialog
    ({
      autoOpen: true,
      modal: true,
      buttons:
        {
          'Yes': function () {
            $(this).dialog('close');
            $(this).find(".yes").click();
          },
          'No': function () {
            $(this).dialog('close');
            $(this).find(".no").click();
          }
        }
    });

The other change I made was to create the confirmBox div within the doConfirm function, like ThulasiRam did in his answer.

Like explained in other answers you need to provide a comparison function. If you would like to keep the definition of that function close to the sort call (e.g. if it only makes sense for this sort) you can define it right there with boost::lambda. Use boost::lambda::bind to call the member function.

To e.g. sort by member variable or function data1:

#include <algorithm>
#include <vector>
#include <boost/lambda/bind.hpp>
#include <boost/lambda/lambda.hpp>
using boost::lambda::bind;
using boost::lambda::_1;
using boost::lambda::_2;

std::vector<myclass> object(10000);
std::sort(object.begin(), object.end(),
    bind(&myclass::data1, _1) < bind(&myclass::data1, _2));

For a direct change, you can use Bootstrap classes in the <a> tag (it won't work in the <div>):

<h4 class="text-center"><a class="text-warning" href="#">Your text</a></h4>

If you use

<select [ngModel]="object">
    <option *ngFor="let object of objects" [ngValue]="object">{{object.name}}</option>
</select>

You need to set the property object in you components class to the item from objects that you want to have pre-selected.

class MyComponent {
  object;
  objects = [{name: 'a'}, {name: 'b'}, {name: 'c'}];
  constructor() {
    this.object = this.objects[1];
  }
}

Ive found another: http://swipejs.com/

seems to work nicely however I encounter an issue with it when paired with bootstrap on the OS X version of Chrome. If total cross-browser compatibility isn't an issue, then you're golden.

Since one cannot put single quotes within single quoted strings, the simplest and most readable option is to use a HEREDOC string

command=$(cat <<'COMMAND'
urxvt -fg '#111111' -bg '#111111'
COMMAND
)

alias rxvt=$command

In the code above, the HEREDOC is sent to the cat command and the output of that is assigned to a variable via the command substitution notation $(..)

Putting a single quote around the HEREDOC is needed since it is within a $()

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

To me the best way to debug on React-Native is by using "Reactotron".

Install Reactotron then add these to your package.json:

"reactotron-apisauce": "^1.1.2",
"reactotron-react-native-under-37": "^1.1.2",
"reactotron-redux": "^1.1.2", 

now, it just the matter of logging in your code. e.g.: console.tron.log('debug')

This can be done from the command line using the SETX command. For example to 'move' your temporary files to another disk:

SETX TEMP d:\tmp

#1 form

a = ('x', 'y')
b = a + ('z',)
print(b)

#2 form

a = ('x', 'y')
b = a + tuple('b')
print(b)

There is an easier way so you don't have to unload the project. Just install this tool called EditProj in Visual Studio:
https://marketplace.visualstudio.com/items?itemName=EdMunoz.EditProj

Then right click edit you will have a new menu item Edit Project File :)

Use Thread.sleep(100);. The unit of time is milliseconds

For example:

public class SleepMessages {
    public static void main(String args[])
        throws InterruptedException {
        String importantInfo[] = {
            "Mares eat oats",
            "Does eat oats",
            "Little lambs eat ivy",
            "A kid will eat ivy too"
        };

        for (int i = 0;
             i < importantInfo.length;
             i++) {
            //Pause for 4 seconds
            Thread.sleep(4000);
            //Print a message
            System.out.println(importantInfo[i]);
        }
    }
}

I'm using this css method in order to simulate placeholder on the input date.

The only thing that need js is to setAttribute of the value, if using React, it works out of the box.

input[type="date"] {_x000D_
  position: relative;_x000D_
}_x000D_
_x000D_
input[type="date"]:before {_x000D_
  content: attr(placeholder);_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  right: 0;_x000D_
  bottom: 0;_x000D_
  background: #fff;_x000D_
  color: rgba(0, 0, 0, 0.65);_x000D_
  pointer-events: none;_x000D_
  line-height: 1.5;_x000D_
  padding: 0 0.5rem;_x000D_
}_x000D_
_x000D_
input[type="date"]:focus:before,_x000D_
input[type="date"]:not([value=""]):before_x000D_
{_x000D_
  display: none;_x000D_
}

<input type="date" placeholder="Choose date" value="" onChange="this.setAttribute('value', this.value)" />

Python includes two functions in the math package; radians converts degrees to radians, and degrees converts radians to degrees.

To match the output of your calculator you need:

>>> math.cos(math.radians(1))
0.9998476951563913

Note that all of the trig functions convert between an angle and the ratio of two sides of a triangle. cos, sin, and tan take an angle in radians as input and return the ratio; acos, asin, and atan take a ratio as input and return an angle in radians. You only convert the angles, never the ratios.

If you want the second highest number you can use

=LARGE(E4:E9;2)

although that doesn't account for duplicates so you could get the same result as the Max

If you want the largest number that is smaller than the maximum number you can use this version

=LARGE(E4:E9;COUNTIF(E4:E9;MAX(E4:E9))+1)

One thing you need to consider is the interaction of checkbox and radio inputs with javascript.

Using below structure:

<label>
  <input onclick="controlCheckbox()" type="checkbox" checked="checkboxState" />
  <span>Label text</span>
</label>

When user clicks on "Label text" controlCheckbox() function will be fired once.

But when input tag is clicked the controlCheckbox() function may be fired twice in some older browsers. That's because both input and label tags trigger onclick event attached to checkbox.

Then you may have some bugs in your checkboxState.

I've run into this issue lately on IE11. I'm not sure if modern browsers have troubles with this structure.

I think that the usage of @Html.LabelForModel() should be explained in more detail.

The LabelForModel Method returns an HTML label element and the property name of the property that is represented by the model.

You could refer to the following code:

Code in model:

using System.ComponentModel;

[DisplayName("MyModel")]
public class MyModel
{
    [DisplayName("A property")]
    public string Test { get; set; }
}

Code in view:

@Html.LabelForModel()
<div class="form-group">

    @Html.LabelFor(model => model.Test, new { @class = "control-label col-md-2" })

    <div class="col-md-10">
        @Html.EditorFor(model => model.Test)
        @Html.ValidationMessageFor(model => model.Test)
    </div>
</div>

Note and update:

Since Git1.7.4 (January 2011), you have git merge --abort, synonymous to "git reset --merge" when a merge is in progress.

But if you want to complete the merge, while somehow nothing remains to be added, then a crude rm -rf .git/MERGE* can be enough for Git to forget about the current merge.

I made something like this to my project

function adjustLine(from, to, line){_x000D_

If you control the remote server, you should probably use CORS, as described in this answer; it's supported in IE8 and up, and all recent versions of FF, GC, and Safari. (But in IE8 and 9, CORS won't allow you to send cookies in the request.)

So, if you don't control the remote server, or if you have to support IE7, or if you need cookies and you have to support IE8/9, you'll probably want to use an iframe technique.

1. Create an iframe with a unique name. (iframes use a global namespace for the entire browser, so pick a name that no other website will use.)
2. Construct a form with hidden inputs, targeting the iframe.
3. Submit the form.

Here's sample code; I tested it on IE6, IE7, IE8, IE9, FF4, GC11, S5.

function crossDomainPost() {
  // Add the iframe with a unique name
  var iframe = document.createElement("iframe");
  var uniqueString = "CHANGE_THIS_TO_SOME_UNIQUE_STRING";
  document.body.appendChild(iframe);
  iframe.style.display = "none";
  iframe.contentWindow.name = uniqueString;

  // construct a form with hidden inputs, targeting the iframe
  var form = document.createElement("form");
  form.target = uniqueString;
  form.action = "http://INSERT_YOUR_URL_HERE";
  form.method = "POST";

  // repeat for each parameter
  var input = document.createElement("input");
  input.type = "hidden";
  input.name = "INSERT_YOUR_PARAMETER_NAME_HERE";
  input.value = "INSERT_YOUR_PARAMETER_VALUE_HERE";
  form.appendChild(input);

  document.body.appendChild(form);
  form.submit();
}

Beware! You won't be able to directly read the response of the POST, since the iframe exists on a separate domain. Frames aren't allowed to communicate with each other from different domains; this is the same-origin policy.

If you control the remote server but you can't use CORS (e.g. because you're on IE8/IE9 and you need to use cookies), there are ways to work around the same-origin policy, for example by using window.postMessage and/or one of a number of libraries allowing you to send cross-domain cross-frame messages in older browsers:

• Porthole
• XSSInterface
• EasyXDM
• jQuery PostMessage Plugin

If you don't control the remote server, then you can't read the response of the POST, period. It would cause security problems otherwise.

One can reproduce the error with the code below:

public ActionResult ClosingTheConnectionAction(){
   try
   {
      //we need to set buffer to false to
      //make sure data is written in chunks
      Response.Buffer = false;  
      var someText = "Some text here to make things happen ;-)";
      var content = GetBytes( someText );

      for(var i=0; i < 100; i++)
      {
         Response.OutputStream.Write(content, 0, content.Length);
      }

      return View();
   }
   catch(HttpException hex)
   {
      if (hex.Message.StartsWith("The remote host closed the connection. The error code is 0x800704CD."))
            {
                //react on remote host closed the connection exception.
                var msg = hex.Message;
            }  
   }
   catch(Exception somethingElseHappened)
   {
      //handle it with some other code
   }

   return View();
} 

Now run the website in debug mode. Put a breakpoint in the loop that writes to the output stream. Go to that action method and after the first iteration passed close the tab of the browser. Hit F10 to continue the loop. After it hit the next iteration you will see the exception. Enjoy your exception :-)

Take a look at PyCrypto. It supports Python 3.2 and does exactly what you want.

From their pip website:

>>> from Crypto.Cipher import AES
>>> obj = AES.new('This is a key123', AES.MODE_CFB, 'This is an IV456')
>>> message = "The answer is no"
>>> ciphertext = obj.encrypt(message)
>>> ciphertext
'\xd6\x83\x8dd!VT\x92\xaa`A\x05\xe0\x9b\x8b\xf1'
>>> obj2 = AES.new('This is a key123', AES.MODE_CFB, 'This is an IV456')
>>> obj2.decrypt(ciphertext)
'The answer is no'

If you want to encrypt a message of an arbitrary size use AES.MODE_CFB instead of AES.MODE_CBC.

I set .navbar-brand { min-height: inherit } which solved the issue for me (thanks @creimers for inspiration).

You can use the ThenBy and ThenByDescending extension methods:

foobarList.OrderBy(x => x.Foo).ThenBy( x => x.Bar)

Assuming

var val = $('#person_data[document_type]').value();

you have these cases:

val === 'NULL';  // actual value is a string with content "NULL"
val === '';      // actual value is an empty string
val === null;    // actual value is null (absence of any value)

So, use what you need.

I think this is because you are using client software and not the server.

• mysql is client
• mysqld is the server

Try: sudo service mysqld start

To check that service is running use: ps -ef | grep mysql | grep -v grep.

Uninstalling:

sudo apt-get purge mysql-server
sudo apt-get autoremove
sudo apt-get autoclean

Re-Installing:

sudo apt-get update
sudo apt-get install mysql-server

Backup entire folder before doing this:

sudo rm /etc/apt/apt.conf.d/50unattended-upgrades*
sudo apt-get update
sudo apt-get upgrade

Let's get to the sources

Description

The MAX_SAFE_INTEGER constant has a value of 9007199254740991 (9,007,199,254,740,991 or ~9 quadrillion). The reasoning behind that number is that JavaScript uses double-precision floating-point format numbers as specified in IEEE 754 and can only safely represent numbers between -(2^53 - 1) and 2^53 - 1.

Safe in this context refers to the ability to represent integers exactly and to correctly compare them. For example, Number.MAX_SAFE_INTEGER + 1 === Number.MAX_SAFE_INTEGER + 2 will evaluate to true, which is mathematically incorrect. See Number.isSafeInteger() for more information.

Because MAX_SAFE_INTEGER is a static property of Number, you always use it as Number.MAX_SAFE_INTEGER, rather than as a property of a Number object you created.

Browser compatibility

The solution for me (openSUSE Leap 42.3, KDE) was to rename the folder ~/.gnupg which apparently contained the cached keys and profiles.

After KDE logout/logon the ssh-add/agent is running again and the folder is created from scratch, but the old keys are all gone.

I didn't have success with the other approaches.

Change BloggerRepository to IBloggerRepository

As far as I can see, you just added heredoc by mistake
No need to use ugly heredoc syntax here.
Just remove it and everything will work:

<p>Hello</p>
<p><?= _("World"); ?></p>

I have Had the same issue and the only Solution i found was open Package manager> Select Microsoft and .Net as Package Source and You will install it..

1. When you want to have wide characters stored in your string. wide depends on the implementation. Visual C++ defaults to 16 bit if i remember correctly, while GCC defaults depending on the target. It's 32 bits long here. Please note wchar_t (wide character type) has nothing to do with unicode. It's merely guaranteed that it can store all the members of the largest character set that the implementation supports by its locales, and at least as long as char. You can store unicode strings fine into std::string using the utf-8 encoding too. But it won't understand the meaning of unicode code points. So str.size() won't give you the amount of logical characters in your string, but merely the amount of char or wchar_t elements stored in that string/wstring. For that reason, the gtk/glib C++ wrapper folks have developed a Glib::ustring class that can handle utf-8.

   If your wchar_t is 32 bits long, then you can use utf-32 as an unicode encoding, and you can store and handle unicode strings using a fixed (utf-32 is fixed length) encoding. This means your wstring's s.size() function will then return the right amount of wchar_t elements and logical characters.

2. Yes, char is always at least 8 bit long, which means it can store all ASCII values.
3. Yes, all major compilers support it.

I'd do it in two statements: DROP DATABASE ???

and then CREATE DATABASE ???

You can use the excecl command

int execl(const char *path, const char *arg, ...);

Like shown here

#include <stdio.h>
#include <unistd.h>
#include <dirent.h>

int main (void) {

   return execl ("/bin/pwd", "pwd", NULL);

}

The second argument will be the name of the process as it will appear in the process table.

Alternatively, you can use the getcwd() function to get the current working directory:

#include <stdio.h>
#include <unistd.h>
#include <dirent.h>
#define MAX 255

int main (void) {
char wd[MAX];
wd[MAX-1] = '\0';

if(getcwd(wd, MAX-1) == NULL) {
  printf ("Can not get current working directory\n");
}
else {
  printf("%s\n", wd);
}
  return 0;
}

Those who are looking for Kotlin solution can use this method,

Here I have shared full code, and also handled enabled status. Check If Application is Installed in Android Kotlin

fun isAppInstalled(packageName: String, context: Context): Boolean {
        return try {
            val packageManager = context.packageManager
            packageManager.getPackageInfo(packageName, 0)
            true
        } catch (e: PackageManager.NameNotFoundException) {
            false
        }
    }

found it under /Users/username/apache-maven-3.3.9/conf

No-one seems to have mentioned this solution. Obvious really - but tripped me over for a moment...

The default access modifier for a new resources file is Internal (or Friend in VB.Net.) Make sure you change this to Public

(in the resx designer there is a dropdown at the top for the access modifier)

Using an Cursor FOR LOOP Statement is my favourite way to do this.

It is safer than using an explicit cursor, because you don't need to remember to close it, so you can't "leak" cursors.

You don't need "into" variables, you don't need to "FETCH", you don't need to catch and handle "NO DATA FOUND" exceptions.

Try it, you'll never go back.

v_column my_table.column%TYPE;

v_column := null;

FOR rMyTable IN (SELECT COLUMN FROM MY_TABLE WHERE ....) LOOP
  v_column := rMyTable.COLUMN;
  EXIT;  -- Exit the loop if you only want the first result.
END LOOP;

There are many ways to get jQuery AJAX response. I am sharing with you two common approaches:

First:

use async=false and within function return ajax-object and later get response ajax-object.responseText

/**
 * jQuery ajax method with async = false, to return response
 * @param  {mix}  selector - your selector
 * @return {mix}           - your ajax response/error
 */
function isSession(selector) {
    return $.ajax({
        type: "POST",
        url: '/order.html',
        data: {
            issession: 1,
            selector: selector
        },
        dataType: "html",
        async: !1,
        error: function() {
            alert("Error occured")
        }
    });
}
// global param
var selector = !0;
// get return ajax object
var ajaxObj = isSession(selector);
// store ajax response in var
var ajaxResponse = ajaxObj.responseText;
// check ajax response
console.log(ajaxResponse);
// your ajax callback function for success
ajaxObj.success(function(response) {
    alert(response);
});

Second:

use $.extend method and make a new function like ajax

/**
 * xResponse function
 *
 * xResponse method is made to return jQuery ajax response
 * 
 * @param  {string} url   [your url or file]
 * @param  {object} your ajax param
 * @return {mix}       [ajax response]
 */
$.extend({
    xResponse: function(url, data) {
        // local var
        var theResponse = null;
        // jQuery ajax
        $.ajax({
            url: url,
            type: 'POST',
            data: data,
            dataType: "html",
            async: false,
            success: function(respText) {
                theResponse = respText;
            }
        });
        // Return the response text
        return theResponse;
    }
});

// set ajax response in var
var xData = $.xResponse('temp.html', {issession: 1,selector: true});

// see response in console
console.log(xData);

you can make it as large as you want...

I wrote more flexible function which can give you random number but not only integer.

function rand(min,max,interval)
{
    if (typeof(interval)==='undefined') interval = 1;
    var r = Math.floor(Math.random()*(max-min+interval)/interval);
    return r*interval+min;
}

var a = rand(0,10); //can be 0, 1, 2 (...) 9, 10
var b = rand(4,6,0.1); //can be 4.0, 4.1, 4.2 (...) 5.9, 6.0

Fixed version.

I use this solution having max(date_entered) and it works very well

SELECT 
  report_id, 
  computer_id, 
  date_entered
FROM reports
GROUP BY computer_id having max(date_entered)

  //insert this php code, at the end after your closing html tag. 

  <?php
  //setting connection to database
  $con = mysqli_connect("localhost","your-username","your-
  passowrd","your-dbname");

  if(isset($_POST['submit_button'])){

     $txt_area = $_POST['update']; 

       $Our_query= "INSERT INTO your-table-name (field1name, field2name) 
                  VALUES ('abc','def')"; // values should match data 
                 //  type to field names

        $insert_query = mysqli_query($con, $Our_query);

        if($insert_query){
            echo "<script>window.open('form.php','_self') </script>"; 
             // supposing form.php is where you have created this form

          }



   } //if statement close         
  ?>

Hope this helps.

If the javascript file is loaded from the admin dashboard, this javascript function will give you the root of your WordPress installation. I use this a lot when I'm building plugins that need to make ajax requests from the admin dashboard.

function getHomeUrl() {
  var href = window.location.href;
  var index = href.indexOf('/wp-admin');
  var homeUrl = href.substring(0, index);
  return homeUrl;
}

For Translating the command to python refer below:-

1)Alternative of cat command is open refer this. Below is the sample

>>> f = open('workfile', 'r')
>>> print f

2)Alternative of grep command refer this

3)Alternative of Cut command refer this

Okay folks, I completely understand the security reasons behind this error message, but sometimes, we do need a workaround... and here's mine. It uses ASP.Net (rather than JavaScript, which this question was based on) but it'll hopefully be useful to someone.

Our in-house app has a webpage where users can create a list of shortcuts to useful files spread throughout our network. When they click on one of these shortcuts, we want to open these files... but of course, Chrome's error prevents this.

This webpage uses AngularJS 1.x to list the various shortcuts.

Originally, my webpage was attempting to directly create an <a href..> element pointing at the files, but this produced the "Not allowed to load local resource" error when a user clicked on one of these links.

<div ng-repeat='sc in listOfShortcuts' id="{{sc.ShtCut_ID}}" class="cssOneShortcutRecord" >
    <div class="cssShortcutIcon">
        <img ng-src="{{ GetIconName(sc.ShtCut_PathFilename); }}">
    </div>
    <div class="cssShortcutName">
        <a ng-href="{{ sc.ShtCut_PathFilename }}" ng-attr-title="{{sc.ShtCut_Tooltip}}" target="_blank" >{{ sc.ShtCut_Name }}</a>
    </div>
</div>

The solution was to replace those <a href..> elements with this code, to call a function in my Angular controller...

<div ng-click="OpenAnExternalFile(sc.ShtCut_PathFilename);" >
    {{ sc.ShtCut_Name }}
</div>

The function itself is very simple...

$scope.OpenAnExternalFile = function (filename) {
    //
    //  Open an external file (i.e. a file which ISN'T in our IIS folder)
    //  To do this, we get an ASP.Net Handler to manually load the file, 
    //  then return it's contents in a Response.
    //
    var URL = '/Handlers/DownloadExternalFile.ashx?filename=' + encodeURIComponent(filename);
    window.open(URL);
}

And in my ASP.Net project, I added a Handler file called DownloadExternalFile.aspx which contained this code:

namespace MikesProject.Handlers
{
    /// <summary>
    /// Summary description for DownloadExternalFile
    /// </summary>
    public class DownloadExternalFile : IHttpHandler
    {
        //  We can't directly open a network file using Javascript, eg
        //      window.open("\\SomeNetworkPath\ExcelFile\MikesExcelFile.xls");
        //
        //  Instead, we need to get Javascript to call this groovy helper class which loads such a file, then sends it to the stream.  
        //      window.open("/Handlers/DownloadExternalFile.ashx?filename=//SomeNetworkPath/ExcelFile/MikesExcelFile.xls");
        //
        public void ProcessRequest(HttpContext context)
        {
            string pathAndFilename = context.Request["filename"];               //  eg  "\\SomeNetworkPath\ExcelFile\MikesExcelFile.xls"
            string filename = System.IO.Path.GetFileName(pathAndFilename);      //  eg  "MikesExcelFile.xls"

            context.Response.ClearContent();

            WebClient webClient = new WebClient();
            using (Stream stream = webClient.OpenRead(pathAndFilename))
            {
                // Process image...
                byte[] data1 = new byte[stream.Length];
                stream.Read(data1, 0, data1.Length);

                context.Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", filename));
                context.Response.BinaryWrite(data1);

                context.Response.Flush();
                context.Response.SuppressContent = true;
                context.ApplicationInstance.CompleteRequest();
            }
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }

And that's it.

Now, when a user clicks on one of my Shortcut links, it calls the OpenAnExternalFile function, which opens this .ashx file, passing it the path+filename of the file we want to open.

This Handler code loads the file, then passes it's contents back in the HTTP response.

And, job done, the webpage opens the external file.

Phew ! Again - there is a reason why Chrome throws this "Not allowed to load local resources" exception, so tread carefully with this... but I'm posting this code just to demonstrate that this is a fairly simple way around this limitation.

Just one last comment: the original question wanted to open the file "C:\002.jpg". You can't do this. Your website will sit on one server (with it's own C: drive) and has no direct access to your user's own C: drive. So the best you can do is use code like mine to access files somewhere on a network drive.

The state of the checkbox will be reflected on whatever model you have it bound to, in this case, $scope.answers[item.questID]

You're thinking too complicated. It's actually just $('#'+openaddress).

I had the same error message from spring's @RestController. My rest controller class was using spring's JpaRepository class and by replacing repository.getOne(id) method call with repository.findOne(id) problem was gone.

ng-Idle looks like the way to go, but I could not figure out Brian F's modifications and wanted to timeout for a sleeping session too, also I had a pretty simple use case in mind. I pared it down to the code below. It hooks events to reset a timeout flag (lazily placed in $rootScope). It only detects the timeout has happened when the user returns (and triggers an event) but that's good enough for me. I could not get angular's $location to work here but again, using document.location.href gets the job done.

I stuck this in my app.js after the .config has run.

app.run(function($rootScope,$document) 
{
  var d = new Date();
  var n = d.getTime();  //n in ms

    $rootScope.idleEndTime = n+(20*60*1000); //set end time to 20 min from now
    $document.find('body').on('mousemove keydown DOMMouseScroll mousewheel mousedown touchstart', checkAndResetIdle); //monitor events

    function checkAndResetIdle() //user did something
    {
      var d = new Date();
      var n = d.getTime();  //n in ms

        if (n>$rootScope.idleEndTime)
        {
            $document.find('body').off('mousemove keydown DOMMouseScroll mousewheel mousedown touchstart'); //un-monitor events

            //$location.search('IntendedURL',$location.absUrl()).path('/login'); //terminate by sending to login page
            document.location.href = 'https://whatever.com/myapp/#/login';
            alert('Session ended due to inactivity');
        }
        else
        {
            $rootScope.idleEndTime = n+(20*60*1000); //reset end time
        }
    }
});

While you are declaring onclick in XML then you must declair method and pass View v as parameter and make the method public...

Ex:
//in xml

If you don't need mutability for your final map, there is Guava's ImmutableMap with its Builder and putAll method which, in contrast to Java's Map interface method, can be chained.

Example of use:

Map<String, Integer> mergeMyTwoMaps(Map<String, Integer> map1, Map<String, Integer> map2) {
  return ImmutableMap.<String, Integer>builder()
      .putAll(map1)
      .putAll(map2)
      .build();
}

Of course, this method can be more generic, use varargs and loop to putAll Maps from arguments etc. but I wanted to show a concept.

Also, ImmutableMap and its Builder have few limitations (or maybe features?):

• they are null hostile (throw NullPointerException - if any key or value in map is null)
• Builder don't accept duplicate keys (throws IllegalArgumentException if duplicate keys were added).

Apart from varargs or overloading, you could consider to aggregate your arguments in a std::vector or other containers (std::map for example). Something like this:

template <typename T> void f(std::vector<T> const&);
std::vector<int> my_args;
my_args.push_back(1);
my_args.push_back(2);
f(my_args);

In this way you would gain type safety and the logical meaning of these variadic arguments would be apparent.

Surely this approach can have performance issues but you should not worry about them unless you are sure that you cannot pay the price. It is a sort of a a "Pythonic" approach to c++ ...

Spring was dependency injection in the begining, then add king of wrappers for almost everything (wrapper over JPA implementations etc).

Long story ... most parts of Spring preffer XML solutions (XML scripting engine ... brrrr), so for DI I use Guice

Good library, but with growing depnedenciec, for example Spring JDBC (maybe one Java jdbc solution with real names parameters) take from maven 4-5 next.

Using Spring MVC (part of "big spring") for web development ... it is "request based" framework, there is holy war "request vs component" ... up to You

Can we see the structure of your table? If I am understanding this, then the assumption made by the query is that a record can be only meta_key - 'lat' or meta_key = 'long' not both because each row only has one meta_key column and can only contain 1 corresponding value, not 2. That would explain why you don't get results when you connect the with an AND; it's impossible.

Makefile part of the question

This is pretty easy, unless you don't need to generalize try something like the code below (but replace space indentation with tabs near g++)

SRC_DIR := .../src
OBJ_DIR := .../obj
SRC_FILES := $(wildcard $(SRC_DIR)/*.cpp)
OBJ_FILES := $(patsubst $(SRC_DIR)/%.cpp,$(OBJ_DIR)/%.o,$(SRC_FILES))
LDFLAGS := ...
CPPFLAGS := ...
CXXFLAGS := ...

main.exe: $(OBJ_FILES)
   g++ $(LDFLAGS) -o $@ $^

$(OBJ_DIR)/%.o: $(SRC_DIR)/%.cpp
   g++ $(CPPFLAGS) $(CXXFLAGS) -c -o $@ $<

Automatic dependency graph generation

A "must" feature for most make systems. With GCC in can be done in a single pass as a side effect of the compilation by adding -MMD flag to CXXFLAGS and -include $(OBJ_FILES:.o=.d) to the end of the makefile body:

CXXFLAGS += -MMD
-include $(OBJ_FILES:.o=.d)

And as guys mentioned already, always have GNU Make Manual around, it is very helpful.

I don't think any of the current answers really do what you said you want. (Correction: I now see that @Gareth Latty / @Lattyware has incorporated my answer into his own as an "Edit" near the end.)

Anyway, here's my take:

Say these are the tab-separated values in your input file:

1   2   3   4   5
6   7   8   9   10
11  12  13  14  15
16  17  18  19  20

then this:

with open("tab-separated-values.txt") as inp:
    print( list(zip(*(line.strip().split('\t') for line in inp))) )

would produce the following:

[('1', '6', '11', '16'), 
 ('2', '7', '12', '17'), 
 ('3', '8', '13', '18'), 
 ('4', '9', '14', '19'), 
 ('5', '10', '15', '20')]

As you can see, it put the k-th element of each row into the k-th array.

Use ld.charAt(0). It will return the first char of the String.

With ld.substring(0, 1), you can get the first character as String.

One could use the queryParam method, passing it parameter name and an array of values:

    public WebTarget queryParam(String name, Object... values);

Example (jersey-client 2.23.2):

    WebTarget target = ClientBuilder.newClient().target(URI.create("http://localhost"));
    target.path("path")
            .queryParam("param_name", Arrays.asList("paramVal1", "paramVal2").toArray())
            .request().get();

This will issue request to following URL:

    http://localhost/path?param_name=paramVal1&param_name=paramVal2

I think the better answer for this questions is

array_diff() 

because it Compares array against one or more other arrays and returns the values in array that are not present in any of the other arrays.

Whereas

array_intersect() returns an array containing all the values of array that are present in all the arguments. Note that keys are preserved.

Here's a script (bash) to automate the first solution by @CodeGnome to restore from a backup (run from the top level of the corrupted repo). The backup doesn't need to be complete, it only needs to have the missing objects.

git fsck 2>&1 | grep -e missing -e invalid | awk '{print $NF}' | sort -u |
    while read entry; do
        mkdir -p .git/objects/${entry:0:2}
        cp ${BACKUP}/objects/${entry:0:2}/${entry:2} .git/objects/${entry:0:2}/${entry:2}
    done

#!/bin/sh
# http://www.tldp.org/LDP/abs/html/io-redirection.html
echo "Hello World"
exec > script.log 2>&1
echo "Start logging out from here to a file"
bad command
echo "End logging out from here to a file"
exec > /dev/tty 2>&1 #redirects out to controlling terminal
echo "Logged in the terminal"

Output:

> ./above_script.sh

Something like this would work

Use ==:

pip install django_modeltranslation==0.4.0-beta2

In java the rows are done first, because a 2 dimension array is considered two separate arrays. Starts with the first row 1 dimension array.

You can use foreach if the object you want to iterate over implements the IEnumerable interface. You need to use for if you can access the object only by index.

In my case it was permission for user account in AD. After set it correctly, it works perfect.

to_date() returns a date at 00:00:00, so you need to "remove" the minutes from the date you are comparing to:

select * 
from table
where trunc(es_date) = TO_DATE('27-APR-12','dd-MON-yy')

You probably want to create an index on trunc(es_date) if that is something you are doing on a regular basis.

The literal '27-APR-12' can fail very easily if the default date format is changed to anything different. So make sure you you always use to_date() with a proper format mask (or an ANSI literal: date '2012-04-27')

Although you did right in using to_date() and not relying on implict data type conversion, your usage of to_date() still has a subtle pitfall because of the format 'dd-MON-yy'.

With a different language setting this might easily fail e.g. TO_DATE('27-MAY-12','dd-MON-yy') when NLS_LANG is set to german. Avoid anything in the format that might be different in a different language. Using a four digit year and only numbers e.g. 'dd-mm-yyyy' or 'yyyy-mm-dd'

var date = new Date("enter your  date");//2018-01-17 14:58:29.013

Just one line is enough no need to do any kind of split, join, etc.:

$scope.ssdate=date.toLocaleDateString();//  mm/dd/yyyy format

If you have a github account and don't want to download software, you can export to github, then download a zip from github.

Using COUNT instead of SUM removes the requirement for an ELSE statement:

SELECT jobId, jobName,
    COUNT(CASE WHEN Priority=1 THEN 1 END) AS Priority1,
    COUNT(CASE WHEN Priority=2 THEN 1 END) AS Priority2,
    COUNT(CASE WHEN Priority=3 THEN 1 END) AS Priority3,
    COUNT(CASE WHEN Priority=4 THEN 1 END) AS Priority4,
    COUNT(CASE WHEN Priority=5 THEN 1 END) AS Priority5
FROM TableName
GROUP BY jobId, jobName

There isn't any function in the standard library (to my knowledge) that will do it, but there are absolutely modules out there which have such functions. However, its easy enough that you can just write your own function:

def normalize(lst):
    s = sum(lst)
    return map(lambda x: float(x)/s, lst)

Sample output:

>>> normed = normalize(raw)
>>> normed
[0.25, 0.5, 0.25]

My recommendation is Virtuous Ten Studio. The tool is free but they suggest a donation. It combines all the necessary steps (unpacking APK, baksmaliing, decompiling, etc.) into one easy-to-use UI-based import process. Within five minutes you should have Java source code, less than it takes to figure out the command line options of one of the above mentioned tools.

Decompiling smali to Java is an inexact process, especially if the smali artifacts went through an obfuscator. You can find several decompilers on the web but only some of them are still maintained. Some will give you better decompiled code than others. Read "better" as in "more understandable" than others. Don't expect that the reverse-engineered Java code will compile out of the box. Virtuous Ten Studio comes with multiple free Java decompilers built-in so you can easily try out different decompilers (the "Generate Java source" step) to see which one gives you the best results, saving you the time to find those decompilers yourself and figure out how to use them. Amongst them is CFR, which is one of the few free and still maintained decompilers.

As output you receive, amongst other things, a folder structure that contains all the decompiled Java source code. You can then import this into IntelliJ IDEA or Eclipse for further editing, analysis (e.g. Go to definition, Find usages), etc.

You can also make it a reusable method by expending JavaScript:

Array.prototype.findIndexBy = function(key, value) {
    return this.findIndex(item => item[key] === value)
}

const peoples = [{name: 'john'}]
const cats = [{id: 1, name: 'kitty'}]

peoples.findIndexBy('name', 'john')
cats.findIndexBy('id', 1)

This can be done in a more portable way:

$ nproc --all
32

Compatible with macOS and Linux.

Generally

Your pkl file is, in fact, a serialized pickle file, which means it has been dumped using Python's pickle module.

To un-pickle the data you can:

import pickle


with open('serialized.pkl', 'rb') as f:
    data = pickle.load(f)

For the MNIST data set

Note gzip is only needed if the file is compressed:

import gzip
import pickle


with gzip.open('mnist.pkl.gz', 'rb') as f:
    train_set, valid_set, test_set = pickle.load(f)

Where each set can be further divided (i.e. for the training set):

train_x, train_y = train_set

Those would be the inputs (digits) and outputs (labels) of your sets.

If you want to display the digits:

import matplotlib.cm as cm
import matplotlib.pyplot as plt


plt.imshow(train_x[0].reshape((28, 28)), cmap=cm.Greys_r)
plt.show()

The other alternative would be to look at the original data:

http://yann.lecun.com/exdb/mnist/

But that will be harder, as you'll need to create a program to read the binary data in those files. So I recommend you to use Python, and load the data with pickle. As you've seen, it's very easy. ;-)

If you add double paranthesis to the ngModel reference you get a two-way binding to your model property. That property can then be read and used in the event handler. In my view that is the most clean approach.

<input type="checkbox" [(ngModel)]="myModel.property" (ngModelChange)="processChange()" />
