You need to generate a python file from your ui file with the pyuic tool (site-packages\pyqt4\bin)

pyuic form1.ui > form1.py

with pyqt4

pyuic4.bat form1.ui > form1.py

Then you can import the form1 into your script.

Adding something after # sets the focus of page to the element with that ID. Simplest solution is to use #/ even if you are using jQuery. However if you are handling the event in jQuery, event.preventDefault() is the way to go.

I have created my own git alias to do exactly this. I'm calling it git freebase! It will take your existing messy, unrebasable feature branch and recreate it so that it becomes a new branch with the same name with its commits squashed into one commit and rebased onto the branch you specify (master by default). At the very end, it will allow you to use whatever commit message you like for your newly "freebased" branch.

Install it by placing the following alias in your .gitconfig:

[alias]
  freebase = "!f() { \
    TOPIC="$(git branch | grep '\\*' | cut -d ' ' -f2)"; \
    NEWBASE="${1:-master}"; \
    PREVSHA1="$(git rev-parse HEAD)"; \
    echo "Freebaseing $TOPIC onto $NEWBASE, previous sha1 was $PREVSHA1"; \
    echo "---"; \
    git reset --hard "$NEWBASE"; \
    git merge --squash "$PREVSHA1"; \
    git commit; \
  }; f"

Use it from your feature branch by running: git freebase <new-base>

I've only tested this a few times, so read it first and make sure you want to run it. As a little safety measure it does print the starting sha1 so you should be able to restore your old branch if anything goes wrong.

I'll be maintaining it in my dotfiles repo on github: https://github.com/stevecrozz/dotfiles/blob/master/.gitconfig

Using ng serve --host 0.0.0.0 will allow you to connect to the ng serve using your ip instead of localhost.

EDIT

In newer versions of the cli, you have to provide your local ip address instead

EDIT 2

In newer versions of the cli (I think v5 and up) you can use 0.0.0.0 as the ip again to host it for anyone on your network to talk to.

You can’t use \s in Java to match white space on its own native character set, because Java doesn’t support the Unicode white space property — even though doing so is strictly required to meet UTS#18’s RL1.2! What it does have is not standards-conforming, alas.

Unicode defines 26 code points as \p{White_Space}: 20 of them are various sorts of \pZ GeneralCategory=Separator, and the remaining 6 are \p{Cc} GeneralCategory=Control.

White space is a pretty stable property, and those same ones have been around virtually forever. Even so, Java has no property that conforms to The Unicode Standard for these, so you instead have to use code like this:

String whitespace_chars =  ""       /* dummy empty string for homogeneity */
                        + "\\u0009" // CHARACTER TABULATION
                        + "\\u000A" // LINE FEED (LF)
                        + "\\u000B" // LINE TABULATION
                        + "\\u000C" // FORM FEED (FF)
                        + "\\u000D" // CARRIAGE RETURN (CR)
                        + "\\u0020" // SPACE
                        + "\\u0085" // NEXT LINE (NEL) 
                        + "\\u00A0" // NO-BREAK SPACE
                        + "\\u1680" // OGHAM SPACE MARK
                        + "\\u180E" // MONGOLIAN VOWEL SEPARATOR
                        + "\\u2000" // EN QUAD 
                        + "\\u2001" // EM QUAD 
                        + "\\u2002" // EN SPACE
                        + "\\u2003" // EM SPACE
                        + "\\u2004" // THREE-PER-EM SPACE
                        + "\\u2005" // FOUR-PER-EM SPACE
                        + "\\u2006" // SIX-PER-EM SPACE
                        + "\\u2007" // FIGURE SPACE
                        + "\\u2008" // PUNCTUATION SPACE
                        + "\\u2009" // THIN SPACE
                        + "\\u200A" // HAIR SPACE
                        + "\\u2028" // LINE SEPARATOR
                        + "\\u2029" // PARAGRAPH SEPARATOR
                        + "\\u202F" // NARROW NO-BREAK SPACE
                        + "\\u205F" // MEDIUM MATHEMATICAL SPACE
                        + "\\u3000" // IDEOGRAPHIC SPACE
                        ;        
/* A \s that actually works for Java’s native character set: Unicode */
String     whitespace_charclass = "["  + whitespace_chars + "]";    
/* A \S that actually works for  Java’s native character set: Unicode */
String not_whitespace_charclass = "[^" + whitespace_chars + "]";

Now you can use whitespace_charclass + "+" as the pattern in your replaceAll.

Sorry ’bout all that. Java’s regexes just don’t work very well on its own native character set, and so you really have to jump through exotic hoops to make them work.

And if you think white space is bad, you should see what you have to do to get \w and \b to finally behave properly!

Yes, it’s possible, and yes, it’s a mindnumbing mess. That’s being charitable, even. The easiest way to get a standards-comforming regex library for Java is to JNI over to ICU’s stuff. That’s what Google does for Android, because OraSun’s doesn’t measure up.

If you don’t want to do that but still want to stick with Java, I have a front-end regex rewriting library I wrote that “fixes” Java’s patterns, at least to get them conform to the requirements of RL1.2a in UTS#18, Unicode Regular Expressions.

I would recommend having a look at this answer of mine, and see if it is relevant to what you are doing. If I understand your real problem, it's that your just not using your async action correctly and updating the redux "store", which will automatically update your component with it's new props.

This section of your code:

componentDidMount() {
      if (this.props.isManager) {
        this.props.dispatch(actions.fetchAllSites())
      } else {
        const currentUserId = this.props.user.get('id')
        this.props.dispatch(actions.fetchUsersSites(currentUserId))
      }  
    }

Should not be triggering in a component, it should be handled after executing your first request.

Have a look at this example from redux-thunk:

function makeASandwichWithSecretSauce(forPerson) {

  // Invert control!
  // Return a function that accepts `dispatch` so we can dispatch later.
  // Thunk middleware knows how to turn thunk async actions into actions.

  return function (dispatch) {
    return fetchSecretSauce().then(
      sauce => dispatch(makeASandwich(forPerson, sauce)),
      error => dispatch(apologize('The Sandwich Shop', forPerson, error))
    );
  };
}

You don't necessarily have to use redux-thunk, but it will help you reason about scenarios like this and write code to match.

One additional benefit to doing it in javascript is you can add / remove the hover effect at different points in time - e.g. hover over table rows changes color, click disables the hover effect and starts edit in place mode.

render: -> <a className="upvotes" onClick={(e) => {this.upvote(e); }}>upvote</a>

In your head element add

<script type="text/javascript" src="myscript.js"></script>

Did you try

$(this).val('test');

instead of

$(this).attr('value', 'test');

val() is generally easier, since the attribute you need to change may be different on different DOM elements.

Here's a one-liner using Maven:

mvn dependency:get -Dartifact=mysql:mysql-connector-java:5.1.38

Then, with default settings, it's available in:

$HOME/.m2/repository/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar

Just replace the version number if you need a different one.

.add_to_cart >>> .form-item:eq(1)

the second .form-item at tree level child from the .add_to_cart

simply run the following command:

ng update

note: this will not update globally.

In case you would like to use timeout middleware and exclude a specific route:

var timeout = require('connect-timeout');
app.use(timeout('5s')); //set 5s timeout for all requests

app.use('/my_route', function(req, res, next) {
    req.clearTimeout(); // clear request timeout
    req.setTimeout(20000); //set a 20s timeout for this request
    next();
}).get('/my_route', function(req, res) {
    //do something that takes a long time
});

Try using the full type name that includes the assembly info, for example:

string typeName = @"MyCompany.MyApp.MyDomain.MyClass, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null";
Type myClassType = Type.GetType(typeName);

I had the same situation when I was using only the the namesspace.classname to get the type of a class in a different assembly and it would not work. Only worked when I included the assembly info in my type string as shown above.

My Best Solution is as follow:

       var dateValue = Date();
       var month = dateValue.substring(4,7);
       var date = dateValue.substring(8,10);
       var year = dateValue.substring(20,24);
       var finaldateString = date+"-"+month+"-"+year;

you can use background-origin:padding-box; and then add some padding where you want, for example: #logo {background-image: url(your/image.jpg); background-origin:padding-box; padding-left: 15%;} This way you attach the image to the div padding box that contains it so you can position it wherever you want.

Another option is to get the stream to a byte[] and use File.WriteAllBytes. This should do:

using (var stream = new MemoryStream())
{
    input.CopyTo(stream);
    File.WriteAllBytes(file, stream.ToArray());
}

Wrapping it in an extension method gives it better naming:

public void WriteTo(this Stream input, string file)
{
    //your fav write method:

    using (var stream = File.Create(file))
    {
        input.CopyTo(stream);
    }

    //or

    using (var stream = new MemoryStream())
    {
        input.CopyTo(stream);
        File.WriteAllBytes(file, stream.ToArray());
    }

    //whatever that fits.
}

You can work around this by setting the X-UA-Compatible meta header for the specific version of IE you are debugging with. This will change the Browser Mode to the version you specify in the header.

For example:

<meta http-equiv="X-UA-Compatible" content="IE=9" />

In order for the Browser Mode to update on the Developer Tools, you must close [the Developer Tools] and reopen again. This will switch to that specific version.

Switching from a minor version to a greater version will work just fine by refreshing, but if you want to switch back from a greater version to a minor version, such as from 9 to 7, you would need to open a new tab and load the page again.

Here's a screenshot:

Try adding

ngModel in module level

The code is same as the above

You will have to assign both left and right property 0 value for margin: auto to center the logo.

So in this case:

#logo {
  background:red;
  height:50px;
  position:absolute;
  width:50px;
  left: 0;
  right: 0;
  margin: 0 auto;
}

You might also want to set position: relative for #header.

This works because, setting left and right to zero will horizontally stretch the absolutely positioned element. Now magic happens when margin is set to auto. margin takes up all the extra space(equally on each side) leaving the content to its specified width. This results in content becoming center aligned.

If your iframe is from another domain, (cross domain), the other answers are not going to help you... you will simply need to use this:

var currentUrl = document.referrer;

and - here you've got the main url!

Swift 2 and below

let date = NSDate()
var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
var dateString = dateFormatter.stringFromDate(date)
println(dateString)

And in Swift 3 and higher this would now be written as:

let date = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
var dateString = dateFormatter.string(from: date)

lastrow = Sheet1.Range("A#").End(xlDown).Row

This is more easy to determine the row count.
Make sure you declare the right variable when it comes to larger rows.
By the way the '#' sign must be a number where you want to start the row count.

since the data ex1221new was not given, so I have created a dummy data and added it to a data frame. Also, the question which was asked has few changes in codes like then ggplot package has deprecated the use of

"scale_area()" and nows uses scale_size_area()
"opts()" has changed to theme()

In my answer,I have stored the plot in mygraph variable and then I have used

mygraph$labels$x="Discharge of materials" #changes x axis title
       mygraph$labels$y="Area Affected" # changes y axis title

And the work is done. Below is the complete answer.

install.packages("Sleuth2")
library(Sleuth2)
library(ggplot2)

ex1221new<-data.frame(Discharge<-c(100:109),Area<-c(120:129),NO3<-seq(2,5,length.out = 10))
discharge<-ex1221new$Discharge
area<-ex1221new$Area
nitrogen<-ex1221new$NO3
p <- ggplot(ex1221new, aes(discharge, area), main="Point")
mygraph<-p + geom_point(aes(size= nitrogen)) + 
  scale_size_area() + ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")+
theme(
 plot.title =  element_text(color="Blue", size=30, hjust = 0.5), 

 # change the styling of both the axis simultaneously from this-
 axis.title = element_text(color = "Green", size = 20, family="Courier",)
 

   # you can change the  axis title from the code below
   mygraph$labels$x="Discharge of materials" #changes x axis title
   mygraph$labels$y="Area Affected" # changes y axis title
   mygraph



   

Also, you can change the labels title from the same formula used above -

mygraph$labels$size= "N2" #size contains the nitrogen level 

It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.

Edit: This is what the forums say:

By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.

To disable:

The best you can do is to draw a button yourself and put that into your spreadsheet. Than you can add a macro to it.

Go into "Insert > Drawing...", Draw a button and add it to the spreadsheet. Than click it and click "assign Macro...", then insert the name of the function you wish to execute there. The function must be defined in a script in the spreadsheet.

Alternatively you can also draw the button somewhere else and insert it as an image.

Sometimes it would be nice to have operator overloading, friend classes and multiple inheritance.

However I still think it was a good decision. If Java would have had operator overloading then we could never be sure of operator meanings without looking through source code. At present that's not necessary. And I think your example of using methods instead of operator overloading is also quite readable. If you want to make things more clear you could always add a comment above hairy statements.

// a = b + c
Complex a, b, c; a = b.add(c);

The answers here are outdated, as of today Sep 30 2016. Gmail is currently rolling out support for the style tag in the head, as well as media queries. If Gmail is your only concern, you're safe to use classes like a modern developer!

For reference, you can check the official gmail CSS docs.

As a side note, Gmail was the only major client that didn't support style (reference, until they update anyway). That means you can almost safely stop putting styles inline. Some of the more obscure clients may still need them.

STA (Single Threaded Apartment) is basically the concept that only one thread will interact with your code at a time. Calls into your apartment are marshaled via windows messages (using a non-visible) window. This allows calls to be queued and wait for operations to complete.

MTA (Multi Threaded Apartment) is where many threads can all operate at the same time and the onus is on you as the developer to handle the thread security.

There is a lot more to learn about threading models in COM, but if you are having trouble understanding what they are then I would say that understanding what the STA is and how it works would be the best starting place because most COM objects are STA’s.

Apartment Threads, if a thread lives in the same apartment as the object it is using then it is an apartment thread. I think this is only a COM concept because it is only a way of talking about the objects and threads they interact with…

You can try the below:

function formatAMPM() {
    var date = new Date();
    var currDate = date.getDate();
    var hours = date.getHours();
    var dayName = getDayName(date.getDay());
    var minutes = date.getMinutes();
    var monthName = getMonthName(date.getMonth());
    var year = date.getFullYear();
    var ampm = hours >= 12 ? 'pm' : 'am';
    hours = hours % 12;
    hours = hours ? hours : 12; // the hour '0' should be '12'
    minutes = minutes < 10 ? '0' + minutes : minutes;
    var strTime = dayName + ' ' + monthName + ' ' + currDate + ' ' + year + ' ' + hours + ':' + minutes + ' ' + ampm;
    alert(strTime);
}

function getMonthName(month) {
    var ar = new Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
    return ar[month];
}

function getDayName(day) {
    var ar1 = new Array("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat");
    return ar1[day];
}

The problem can also be the ordering of your style sheet imports. I had to move my custom style sheet import below the bootstrap import.

Assuming two apps TestA and TestB. TestB wants to query if TestA is installed. "TestA" defines the following URL scheme in its info.plist file:

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>testA</string>
        </array>
    </dict>
</array>

The second app "TestB" tries to find out if "TestA" is installed by calling:

[[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"TestA://"]];

But this will normally return NO in iOS9 because "TestA" needs to be added to the LSApplicationQueriesSchemes entry in TestB's info.plist file. This is done by adding the following code to TestB's info.plist file:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>TestA</string>
</array>

A working implementation can be found here: https://github.com/gatzsche/LSApplicationQueriesSchemes-Working-Example

        }
    };
}

The function will be automatically targeted into the surrounding namespace Math (even though its definition appears within the scope of that class) but will not be visible unless you call operator<< with a Matrix object which will make argument dependent lookup find that operator definition. That can sometimes help with ambiguous calls, since it's invisible for argument types other than Matrix. When writing its definition, you can also refer directly to names defined in Matrix and to Matrix itself, without qualifying the name with some possibly long prefix and providing template parameters like Math::Matrix<TypeA, N>.

Prior to C++11, you cannot initialise an array using type[]. However the latest c++11 provides(unifies) the initialisation, so you can do it in this way:

string* pStr = new string[3] { "hi", "there"};

See http://www2.research.att.com/~bs/C++0xFAQ.html#uniform-init

Try list comprehension and string.strip():

>>> mystr = "L1\nL2\n\nL3\nL4\n  \n\nL5"
>>> mystr.split('\n')
['L1', 'L2', '', 'L3', 'L4', '  ', '', 'L5']
>>> [line for line in mystr.split('\n') if line.strip() != '']
['L1', 'L2', 'L3', 'L4', 'L5']

Try

<IfModule mod_rewrite.so>
...

</IfModule>

instead of <IfModule mod_rewrite.c>

Well, not always. Using cookies, you are good. But the "can I safely rely on the id being present" urged me to extend the discussion with an important point (mostly for reference, as the visitor count of this page seems quite high).

PHP can be configured to maintain sessions by URL-rewriting, instead of cookies. (How it's good or bad (<-- see e.g. the topmost comment there) is a separate question, let's now stick to the current one, with just one side-note: the most prominent issue with URL-based sessions -- the blatant visibility of the naked session ID -- is not an issue with internal Ajax calls; but then, if it's turned on for Ajax, it's turned on for the rest of the site, too, so there...)

In case of URL-rewriting (cookieless) sessions, Ajax calls must take care of it themselves that their request URLs are properly crafted. (Or you can roll your own custom solution. You can even resort to maintaining sessions on the client side, in less demanding cases.) The point is the explicit care needed for session continuity, if not using cookies:

1. If the Ajax calls just extract URLs verbatim from the HTML (as received from PHP), that should be OK, as they are already cooked (umm, cookified).

2. If they need to assemble request URIs themselves, the session ID needs to be added to the URL manually. (Check here, or the page sources generated by PHP (with URL-rewriting on) to see how to do it.)

From OWASP.org:

Effectively, the web application can use both mechanisms, cookies or URL parameters, or even switch from one to the other (automatic URL rewriting) if certain conditions are met (for example, the existence of web clients without cookies support or when cookies are not accepted due to user privacy concerns).

From a Ruby-forum post:

When using php with cookies, the session ID will automatically be sent in the request headers even for Ajax XMLHttpRequests. If you use or allow URL-based php sessions, you'll have to add the session id to every Ajax request url.

In your view:

{% if user.is_authenticated %}
<p>{{ user }}</p>
{% endif %}

In you controller functions add decorator:

from django.contrib.auth.decorators import login_required
@login_required
def privateFunction(request):

you can also use

$result = curl_exec($ch);
return response()->json(json_decode($result));

Nobody did point the subtle difference in the semantics of the functions name() and local-name().

• name(someNode) returns the full name of the node, and that includes the prefix and colon in case the node is an element or an attribute.
• local-name(someNode) returns only the local name of the node, and that doesn't include the prefix and colon in case the node is an element or an attribute.

Therefore, in situations where a name may belong to two different namespaces, one must use the name() function in order for these names to be still distinguished.

And, BTW, it is possible to specify both functions without any argument:

name() is an abbreviation for name(.)

local-name() is an abbreviation for local-name(.)

Finally, do remember that not only elements and attributes have names, these two functions can also be used on PIs and on these they are identical).

There is no space allocated for the strings. use array (or) pointers with malloc() and free()

Other than that

#import <stdio.h>
#import <string.h>

should be

#include <stdio.h>
#include <string.h>

NOTE:

• anything that is malloc()ed must be free()'ed
• you need to allocate n + 1 bytes for a string which is of length n (the last byte is for \0)

Please you the following code as a reference

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

int main(int argc, char *argv[])
{
    //char *str1 = "First string";
    char *str1 = "First string is a big string";
    char *str2 = NULL;

    if ((str2 = (char *) malloc(sizeof(char) * strlen(str1) + 1)) == NULL) {
        printf("unable to allocate memory \n");
        return -1; 
    }   

    strcpy(str2, str1);

    printf("str1 : %s \n", str1);
    printf("str2 : %s \n", str2);

    free(str2);
    return 0;
}

One thing to be mindful of is setting strings then referring back to them. You have to make sure the quotes aren't colliding.

 set start_date = '2019-01-21';
 select ${hiveconf:start_date}; 

When setting dates then referring to them in code as the strings can conflict. This wouldn't work with the start_date set above.

 '${hiveconf:start_date}'

We have to be mindful of not setting twice single or double quotes for strings when referring back to them in the query.

A static method, field, property, or event is callable on a class even when no instance of the class has been created. If any instances of the class are created, they cannot be used to access the static member. Only one copy of static fields and events exists, and static methods and properties can only access static fields and static events. Static members are often used to represent data or calculations that do not change in response to object state; for instance, a math library might contain static methods for calculating sine and cosine. Static class members are declared using the static keyword before the return type of the membe

Don't use the -g or --grep option, that pattern operates on the name of the test inside of it(), not the filesystem. The current documentation is misleading and/or outright wrong concerning this. To limit the entire command to a portion of the filesystem, you can pass a pattern as the last argument (its not a flag).

For example, this command will set your reporter to spec but will only test js files immediately inside of the server-test directory:

mocha --reporter spec server-test/*.js

This command will do the same as above, plus it will only run the test cases where the it() string/definition of a test begins with "Fnord:":

mocha --reporter spec --grep "Fnord:" server-test/*.js

I struggled with the same issue when trying to feed floats to the classifiers. I wanted to keep floats and not integers for accuracy. Try using regressor algorithms. For example:

import numpy as np
from sklearn import linear_model
from sklearn import svm

classifiers = [
    svm.SVR(),
    linear_model.SGDRegressor(),
    linear_model.BayesianRidge(),
    linear_model.LassoLars(),
    linear_model.ARDRegression(),
    linear_model.PassiveAggressiveRegressor(),
    linear_model.TheilSenRegressor(),
    linear_model.LinearRegression()]

trainingData    = np.array([ [2.3, 4.3, 2.5],  [1.3, 5.2, 5.2],  [3.3, 2.9, 0.8],  [3.1, 4.3, 4.0]  ])
trainingScores  = np.array( [3.4, 7.5, 4.5, 1.6] )
predictionData  = np.array([ [2.5, 2.4, 2.7],  [2.7, 3.2, 1.2] ])

for item in classifiers:
    print(item)
    clf = item
    clf.fit(trainingData, trainingScores)
    print(clf.predict(predictionData),'\n')

No you cannot get the MAC address in JavaScript, mainly because the MAC address uniquely identifies the running computer so it would be a security vulnerability.

Now if all you need is a unique identifier, I suggest you create one yourself using some cryptographic algorithm and store it in a cookie.

If you really need to know the MAC address of the computer AND you are developing for internal applications, then I suggest you use an external component to do that: ActiveX for IE, XPCOM for Firefox (installed as an extension).

I liked the bubble sort extension method approach on "Richie"'s blog above, but I don't necessarily want to just sort comparing the entire object. I more often want to sort on a specific property of the object. So I modified it to accept a key selector the way OrderBy does so you can choose which property to sort on:

    public static void Sort<TSource, TKey>(this ObservableCollection<TSource> source, Func<TSource, TKey> keySelector)
    {
        if (source == null) return;

        Comparer<TKey> comparer = Comparer<TKey>.Default;

        for (int i = source.Count - 1; i >= 0; i--)
        {
            for (int j = 1; j <= i; j++)
            {
                TSource o1 = source[j - 1];
                TSource o2 = source[j];
                if (comparer.Compare(keySelector(o1), keySelector(o2)) > 0)
                {
                    source.Remove(o1);
                    source.Insert(j, o1);
                }
            }
        }
    }

Which you would call the same way you would call OrderBy except it will sort the existing instance of your ObservableCollection instead of returning a new collection:

ObservableCollection<Person> people = new ObservableCollection<Person>();
...

people.Sort(p => p.FirstName);

How are you opening the rendered Markdown?

If you host it over HTTP, i.e. you access it via http:// or https://, most modern browsers will refuse to open local links, e.g. with file://. This is a security feature:

For security purposes, Mozilla applications block links to local files (and directories) from remote files. This includes linking to files on your hard drive, on mapped network drives, and accessible via Uniform Naming Convention (UNC) paths. This prevents a number of unpleasant possibilities, including:

• Allowing sites to detect your operating system by checking default installation paths
• Allowing sites to exploit system vulnerabilities (e.g., C:\con\con in Windows 95/98)
• Allowing sites to detect browser preferences or read sensitive data

There are some workarounds listed on that page, but my recommendation is to avoid doing this if you can.

You can turn on your PHP errors with error_reporting:

error_reporting(E_ALL);
ini_set('display_errors', 'on');

Edit: It's possible that even after putting this, errors still don't show up. This can be caused if there is a fatal error in the script. From PHP Runtime Configuration:

Although display_errors may be set at runtime (with ini_set()), it won't have any affect if the script has fatal errors. This is because the desired runtime action does not get executed.

You should set display_errors = 1 in your php.ini file and restart the server.

Try PEAR's HTTP_Request2 package to easily send POST requests. Alternatively, you can use PHP's curl functions or use a PHP stream context.

HTTP_Request2 also makes it possible to mock out the server, so you can unit-test your code easily

Ross, you can use Arrays.copyof() or Arrays.copyOfRange() too.

Integer[] integerArray = Arrays.copyOf(a, a.length, Integer[].class);
Integer[] integerArray = Arrays.copyOfRange(a, 0, a.length, Integer[].class);

Here the reason to hitting an ClassCastException is you can't treat an array of Integer as an array of Object. Integer[] is a subtype of Object[] but Object[] is not a Integer[].

And the following also will not give an ClassCastException.

Object[] a = new Integer[1];
Integer b=1;
a[0]=b;
Integer[] c = (Integer[]) a;

Best practice says to implement it by your own using local boolean field: http://www.niedermann.dk/2009/06/18/BestPracticeDisposePatternC.aspx

Have you tried using lazy evaluation of expressions like disabled || someAction()?

Lets assume I defined something like so in my controller:

$scope.disabled = true;

Then I can disabling a link and apply inline styles like so:

<a data-ng-click="disabled || (GoTo('#/employer/'))" data-ng-style="disabled && { 'background-color': 'rgba(99, 99, 99, 0.5)', }">Higher Level</a>

Or better still disable a link and apply a class like so:

<a data-ng-click="disabled || (GoTo('#/employer/'))" data-ng-class="{ disabled: disabled }">Higher Level</a>

Note: that you will have a class="disabled" applied to DOM element by that statement.

At this stage you just need to handle what you action GoTo() will do. In my case its as simple as redirect to associated state:

$scope.GoTo = function (state) {
    if (state != undefined && state.length > 0) {
        $window.location.hash = state;
    }
};

Rather than being limited by ngDisabled you are limited by what you decide to do.

With this technique I successfully applied permission level checking to enable or disable user access to certain part of my module.

Simple plunker to demonstrate the point

A simpler solution is to use the static convenience method scanFile():

File imageFile = ...
MediaScannerConnection.scanFile(this, new String[] { imageFile.getPath() }, new String[] { "image/jpeg" }, null);

where this is your activity (or whatever context), the mime-type is only necessary if you are using non-standard file extensions and the null is for the optional callback (which we don't need for such a simple case).

You might want to try Catel. It allows you to define a DataWindow class (instead of Window), and that class automatically creates the view model for you. This way, you can use the declaration of the ViewModel as you did in your original post, and the view model will still be created and set as DataContext.

See this article for an example.

this better:

data: [$(this).serialize(),$.param({NonFormValue: NonFormValue})].join('&')

The endpoint of the term is the URL that is focused on creating a request. Take a look at the following examples from different points:

/api/groups/6/workings/1
/api/v2/groups/5/workings/2
/api/workings/3

They can clearly access the same source in a given API.

'Fraid so. I'd make an HTML page with a stylesheet, then use jQuery to apply the stylesheet to the style attr of each element. Something like this:

var styleAttributes = ['color','font-size']; // all the attributes you've applied in your stylesheet
for (i in styleAttributes) {
    $('body *').css(styleAttributes[i],function () {
        $(this).css(styleAttributes[i]);
    });
}

Then copy the DOM and use that in the email.

I had a similar problem, looking for grep/pattern regex and the "matched pattern found" as output.

At the end I used egrep (same regex on grep -e or -G didn't give me the same result of egrep) with the option -o

so, I think that could be something similar to (I'm NOT a regex Master) :

egrep -o "the*|this{1}|thoroughly{1}" filename

This is an old topic, but in case anyone else is still looking...

I was having trouble after an undock event. An open db connection saved in a global object would error, even after reconnecting to the network. This was due to the TCP connection being forcibly terminated by remote host. (Error -2147467259: TCP Provider: An existing connection was forcibly closed by the remote host.)

However, the error would only show up after the first transaction was attempted. Up to that point, neither Connection.State nor Connection.Version (per solutions above) would reveal any error.

So I wrote the small sub below to force the error - hope it's useful.

Performance testing on my setup (Access 2016, SQL Svr 2008R2) was approx 0.5ms per call.

nodeName is the attribute you are looking for. For example:

var elt = document.getElementById('foo');
console.log(elt.nodeName);

Note that nodeName returns the element name capitalized and without the angle brackets, which means that if you want to check if an element is an <div> element you could do it as follows:

elt.nodeName == "DIV"

While this would not give you the expected results:

elt.nodeName == "<div>"

In code, you could do

ed_ins.setInputType(InputType.TYPE_CLASS_NUMBER);

Old question, but there is much simpler way if you are dealing with full path names at the shell level:

   abspath="$( cd "$path" && pwd )"

As the cd happens in a subshell it does not impact the main script.

Two variations, supposing your shell built-in commands accept -L and -P, are:

   abspath="$( cd -P "$path" && pwd -P )"    #physical path with resolved symlinks
   abspath="$( cd -L "$path" && pwd -L )"    #logical path preserving symlinks

Personally, I rarely need this later approach unless I'm fascinated with symbolic links for some reason.

FYI: variation on obtaining the starting directory of a script which works even if the script changes it's current directory later on.

name0="$(basename "$0")";                  #base name of script
dir0="$( cd "$( dirname "$0" )" && pwd )"; #absolute starting dir

The use of CD assures you always have the absolute directory, even if the script is run by commands such as ./script.sh which, without the cd/pwd, often gives just .. Useless if the script does a cd later on.

Surprised no one mentioned a simple if statement can make sure your loop only gets executed once per format (on the first column, of the first row).

    private void dgv_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
    {
        // once per format
        if (e.ColumnIndex == 0 && e.RowIndex == 0)
        {
            foreach (DataGridViewRow row in dgv.Rows)
                if (row != null)
                    row.DefaultCellStyle.BackColor = Color.Red;
        }
    }

Try this,

Using foreach Loop:

foreach (GridViewRow row in GridView1.Rows)
{
     CheckBox chk = row.Cells[0].Controls[0] as CheckBox;
     if (chk != null && chk.Checked)
     {
       // ...
     }
}

Use it in OnRowCommand event and get checked CheckBox value.

GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);
int requisitionId = Convert.ToInt32(e.CommandArgument);
CheckBox cbox = (CheckBox)row.Cells[3].Controls[0];

As far as I read about it today, you can't debug anything else than node.js, JavaScript and TypeScript at the moment, but they said they want to add new languages which you can debug. The editor is still in development. Nevertheless, I don't think there will be a php debugger in the future since php is serverside, so you can't debug it on your client alone.

If you want to debug php, I can recommend xDebug.

Updated:

Now, it is possible to debug with VS code. You need to install XDebug and php-debug extension for VScode.

For Android device screen coordinates, below concept will work.

Display mdisp = getWindowManager().getDefaultDisplay();
Point mdispSize = new Point();
mdisp.getSize(mdispSize);
int maxX = mdispSize.x; 
int maxY = mdispSize.y;

EDIT:- ** **for devices supporting android api level older than 13. Can use below code.

    Display mdisp = getWindowManager().getDefaultDisplay();
    int maxX= mdisp.getWidth();
    int maxY= mdisp.getHeight();

(x,y) :-

1) (0,0) is top left corner.

2) (maxX,0) is top right corner

3) (0,maxY) is bottom left corner

4) (maxX,maxY) is bottom right corner

here maxX and maxY are screen maximum height and width in pixels, which we have retrieved in above given code.

I had a similar problem.
Basically here the problem is there are probably two instances of mysql running.
A) One running at /etc/init.d
B) Lamp being installed at /opt/lamp
Solution :
Step 1 :- Find all mysql running instances using commnad "find / | grep mysqld"
Step 2 :- Shutdown the services running at /etc/init.d using service mysql stop
Step 3 :- Restart your Lamp services using /opt/lamp/lamp restart

You should be good to go :)

This is a simple way to identify the application related storage paths of a particular app.

Steps:

1. Have the android device connected to your mac or android emulator open
2. Open the terminal
3. adb shell
4. find .

The "find ." command will list all the files with their paths in the terminal.

After this, just search for your app with the bundle identifier and you can use adb pull command to download the files to your local directory.

How about REGEX version:

static final Pattern PATTERN = Pattern.compile("(.*)\\.(.*)");

Matcher m = PATTERN.matcher(path);
if (m.find()) {
    System.out.println("File path/name: " + m.group(1));
    System.out.println("Extention: " + m.group(2));
}

or with null extension supported:

static final Pattern PATTERN =
    Pattern.compile("((.*\\" + File.separator + ")?(.*)(\\.(.*)))|(.*\\" + File.separator + ")?(.*)");

class Separated {
    String path, name, ext;
}

Separated parsePath(String path) {
    Separated res = new Separated();
    Matcher m = PATTERN.matcher(path);
    if (m.find()) {
        if (m.group(1) != null) {
            res.path = m.group(2);
            res.name = m.group(3);
            res.ext = m.group(5);
        } else {
            res.path = m.group(6);
            res.name = m.group(7);
        }
    }
    return res;
}


Separated sp = parsePath("/root/docs/readme.txt");
System.out.println("path: " + sp.path);
System.out.println("name: " + sp.name);
System.out.println("Extention: " + sp.ext);

result for *nix:
path: /root/docs/
name: readme
Extention: txt

for windows, parsePath("c:\windows\readme.txt"):
path: c:\windows\

3. Relative URL:/index.jsp (Select your project root URL)

You need to give a relative file path of <a href="../index.html">Home</a>

Alternately you can specify a link from the root of your site with <a href="/pages/en/index.html">Home</a>

.. and . have special meanings in file paths, .. means up one directory and . means current directory.

so <a href="index.html">Home</a> is the same as <a href="./index.html">Home</a>

RookieRick is right, using DataGridTemplateColumn instead of DataGridComboBoxColumn gives a much simpler XAML.

Moreover, putting the CompanyItem list directly accessible from the GridItem allows you to get rid of the RelativeSource.

IMHO, this give you a very clean solution.

XAML:

<DataGrid AutoGenerateColumns="False" ItemsSource="{Binding GridItems}" >
    <DataGrid.Resources>
        <DataTemplate x:Key="CompanyDisplayTemplate" DataType="vm:GridItem">
            <TextBlock Text="{Binding Company}" />
        </DataTemplate>
        <DataTemplate x:Key="CompanyEditingTemplate" DataType="vm:GridItem">
            <ComboBox SelectedItem="{Binding Company}" ItemsSource="{Binding CompanyList}" />
        </DataTemplate>
    </DataGrid.Resources>
    <DataGrid.Columns>
        <DataGridTextColumn Binding="{Binding Name}" />
        <DataGridTemplateColumn CellTemplate="{StaticResource CompanyDisplayTemplate}"
                                CellEditingTemplate="{StaticResource CompanyEditingTemplate}" />
    </DataGrid.Columns>
</DataGrid>

View model:

public class GridItem
{
    public string Name { get; set; }
    public CompanyItem Company { get; set; }
    public IEnumerable<CompanyItem> CompanyList { get; set; }
}

public class CompanyItem
{
    public int ID { get; set; }
    public string Name { get; set; }

    public override string ToString() { return Name; }
}

public class ViewModel
{
    readonly ObservableCollection<CompanyItem> companies;

    public ViewModel()
    {
        companies = new ObservableCollection<CompanyItem>{
            new CompanyItem { ID = 1, Name = "Company 1" },
            new CompanyItem { ID = 2, Name = "Company 2" }
        };

        GridItems = new ObservableCollection<GridItem> {
            new GridItem { Name = "Jim", Company = companies[0], CompanyList = companies}
        };
    }

    public ObservableCollection<GridItem> GridItems { get; set; }
}

Most of the time we login to remote server using ssh. If you start a shell script and you logout then the process is killed. Nohup helps to continue running the script in background even after you log out from shell.

Nohup command name &
eg: nohup sh script.sh &

Nohup catches the HUP signals. Nohup doesn't put the job automatically in the background. We need to tell that explicitly using &

There is a known bug with specifying default command timeout within the EF connection string.

http://bugs.mysql.com/bug.php?id=56806

Remove the value from the connection string and set it on the data context object itself. This will work if you remove the conflicting value from the connection string.

Entity Framework Core 1.0:

this.context.Database.SetCommandTimeout(180);

Entity Framework 6:

this.context.Database.CommandTimeout = 180;

Entity Framework 5:

((IObjectContextAdapter)this.context).ObjectContext.CommandTimeout = 180;

Entity Framework 4 and below:

this.context.CommandTimeout = 180;

Just wanted to add another simple way someone can sort the the WPF ListView

void SortListView(ListView listView)
{
    IEnumerable listView_items = listView.Items.SourceCollection;
    List<MY_ITEM_CLASS> listView_items_to_list = listView_items.Cast<MY_ITEM_CLASS>().ToList();

    Comparer<MY_ITEM_CLASS> scoreComparer = Comparer<MY_ITEM_CLASS>.Create((first, second) => first.COLUMN_NAME.CompareTo(second.COLUMN_NAME));

    listView_items_to_list.Sort(scoreComparer);
    listView.ItemsSource = null;
    listView.Items.Clear();
    listView.ItemsSource = listView_items_to_list;
}

Another way around using cross join would be to specify column names inside cross join

select name, Subject, Marks 
from studentmarks
Cross Join (
values (Maths,'Maths'),(Science,'Science'),(English,'English')
) un(Marks, Subject)
where marks is not null;

Convert the string into char array with all the letters in lower case:

char c[] = str.toLowerCase().toCharArray();

Then you can use Character.isLetterOrDigit(c[index]) to find out which index has special characters.

Different languages do different things with different levels of efficiency.

The Benchmarks Game has a whole load of different programming problems implemented in a lot of different languages.

datetime.now() is being evaluated once, when your class is instantiated. Try removing the parenthesis so that the function datetime.now is returned and THEN evaluated. I had the same issue with setting default values for my DateTimeFields and wrote up my solution here.

Here's my quick and simple function for getting the absolute path from a relative path.

The difference from the accepted answer is that this function can handle relative paths that moves up to parent folders.

Example:

Workbooks.Open FileName:=GetAbsolutePath("..\..\TRICATEndurance Summary.html")

Code:

' Gets an absolute path from a relative path in the active workbook
Public Function GetAbsolutePath(relativePath As String) As String
    
    Dim absPath As String
    Dim pos As Integer
    
    absPath = ActiveWorkbook.Path
    
    ' Make sure paths are in correct format
    relativePath = Replace(relativePath, "/", "\")
    absPath = Replace(absPath, "/", "\")
    
    Do While Left$(relativePath, 3) = "..\"
    
        ' Remove level from relative path
        relativePath = Mid$(relativePath, 4)
        
        ' Remove level from absolute path
        pos = InStrRev(absPath, "\")
        absPath = Left$(absPath, pos - 1)
    
    Loop
    
    GetAbsolutePath = PathCombine(absPath, relativePath)
    
End Function

This has bitten me a second time so I thought might be worth mentioning. The line listen_addresses = '*' in the postgresql.conf is by default commented. Be sure to uncomment (remove the pound sign, # at the beginning) it after updating otherwise, remote connections will continue to be blocked.

Check this

UPDATE some_table SET some_field = REPLACE("Column Name/String", 'Search String', 'Replace String')

Eg with sample string:

UPDATE some_table SET some_field = REPLACE("this is test string", 'test', 'sample')

EG with Column/Field Name:

UPDATE some_table SET some_field = REPLACE(columnName, 'test', 'sample')

I combined all of the above answers and created a shell function that would suit my needs. This is from a cygwin terminal of my 2 Windows10 machines where I had a shared folder between them. I need to be able to handle the following:

• cat file.cpp | tx
• tx < file.cpp
• tx file.cpp

Where a specific filename is specified, I need to used the same filename during copy. Where input data stream has been piped thru, then i need to generate a temporary filename having the hour minute and seconds. The shared mainfolder has subfolders of the days of the week. This is for organizational purposes.

Behold, the ultimate script for my needs:

tx ()
{
  if [ $# -eq 0 ]; then
    local TMP=/tmp/tx.$(date +'%H%M%S')
    while IFS= read -r line; do
        echo "$line"
    done < /dev/stdin > $TMP
    cp $TMP //$OTHER/stargate/$(date +'%a')/
    rm -f $TMP
  else
    [ -r $1 ] && cp $1 //$OTHER/stargate/$(date +'%a')/ || echo "cannot read file"
  fi
}

If there is any way that you can see to further optimize this, I would like to know.

Here is how I do it. This way I can actually get a function to simulate returning multiple values;

function foo($array) 
{ 
    foreach($array as $_key => $_value) 
    {
       $str .= "{$_key}=".$_value.'&';
    }
    return $str = substr($str, 0, -1);
} 

/* Set the variables to pass to function, in an Array */

    $waffles['variable1'] = "value1"; 
    $waffles['variable2'] = "value2"; 
    $waffles['variable3'] = "value3"; 

/* Call Function */

    parse_str( foo( $waffles ));

/* Function returns multiple variable/value pairs */

    echo $variable1 ."<br>";
    echo $variable2 ."<br>";
    echo $variable3 ."<br>";

Especially usefull if you want, for example all fields in a database to be returned as variables, named the same as the database table fields. See 'db_fields( )' function below.

For example, if you have a query

select login, password, email from members_table where id = $id

Function returns multiple variables:

$login, $password and $email

Here is the function:

function db_fields($field, $filter, $filter_by,  $table = 'members_table') {

 /*
    This function will return as variable names, all fields that you request, 
    and the field values assigned to the variables as variable values.  

    $filter_by = TABLE FIELD TO FILTER RESULTS BY
    $filter =  VALUE TO FILTER BY
    $table = TABLE TO RUN QUERY AGAINST

    Returns single string value or ARRAY, based on whether user requests single
    field or multiple fields.

    We return all fields as variable names. If multiple rows
    are returned, check is_array($return_field); If > 0, it contains multiple rows.
    In that case, simply run parse_str($return_value) for each Array Item. 
*/
    $field = ($field == "*") ? "*,*" : $field;
    $fields = explode(",",$field);

    $assoc_array = ( count($fields) > 0 ) ? 1 : 0;

    if (!$assoc_array) {
        $result = mysql_fetch_assoc(mysql_query("select $field from $table where $filter_by = '$filter'"));
        return ${$field} = $result[$field];
    }
    else
    {
        $query = mysql_query("select $field from $table where $filter_by = '$filter'");
        while ($row = mysql_fetch_assoc($query)) {
            foreach($row as $_key => $_value) {
                $str .= "{$_key}=".$_value.'&';
            }
            return $str = substr($str, 0, -1);
        }
    }
}

Below is a sample call to function. So, If we need to get User Data for say $user_id = 12345, from the members table with fields ID, LOGIN, PASSWORD, EMAIL:

$filter = $user_id;
$filter_by = "ID";
$table_name = "members_table"

parse_str(db_fields('LOGIN, PASSWORD, EMAIL', $filter, $filter_by, $table_name));

/* This will return the following variables: */

echo $LOGIN ."<br>";
echo $PASSWORD ."<br>";
echo $EMAIL ."<br>";

We could also call like this:

parse_str(db_fields('*', $filter, $filter_by, $table_name));

The above call would return all fields as variable names.

Now we can do this with:

<style type="text/css" media="print">
@page {
    size: auto;   /* auto is the initial value */
    margin: 0;  /* this affects the margin in the printer settings */
}
</style>

J2ME Map Route Provider

maps.google.com has a navigation service which can provide you route information in KML format.

To get kml file we need to form url with start and destination locations:

public static String getUrl(double fromLat, double fromLon,
                            double toLat, double toLon) {// connect to map web service
    StringBuffer urlString = new StringBuffer();
    urlString.append("http://maps.google.com/maps?f=d&hl=en");
    urlString.append("&saddr=");// from
    urlString.append(Double.toString(fromLat));
    urlString.append(",");
    urlString.append(Double.toString(fromLon));
    urlString.append("&daddr=");// to
    urlString.append(Double.toString(toLat));
    urlString.append(",");
    urlString.append(Double.toString(toLon));
    urlString.append("&ie=UTF8&0&om=0&output=kml");
    return urlString.toString();
}

Next you will need to parse xml (implemented with SAXParser) and fill data structures:

public class Point {
    String mName;
    String mDescription;
    String mIconUrl;
    double mLatitude;
    double mLongitude;
}

public class Road {
    public String mName;
    public String mDescription;
    public int mColor;
    public int mWidth;
    public double[][] mRoute = new double[][] {};
    public Point[] mPoints = new Point[] {};
}

Network connection is implemented in different ways on Android and Blackberry, so you will have to first form url:

 public static String getUrl(double fromLat, double fromLon,
     double toLat, double toLon)

then create connection with this url and get InputStream.
Then pass this InputStream and get parsed data structure:

 public static Road getRoute(InputStream is)

class MapPathScreen extends MainScreen {
    MapControl map;
    Road mRoad = new Road();

        double toLat = 50.45, toLon = 30.523333;
        String url = RoadProvider.getUrl(fromLat, fromLon, toLat, toLon);
        InputStream is = getConnection(url);
        mRoad = RoadProvider.getRoute(is);
        map = new MapControl();
        add(new LabelField(mRoad.mName));
        add(new LabelField(mRoad.mDescription));
        add(map);
    }
    protected void onUiEngineAttached(boolean attached) {
        super.onUiEngineAttached(attached);
        if (attached) {
            map.drawPath(mRoad);
        }
    }
    private InputStream getConnection(String url) {
        HttpConnection urlConnection = null;
        InputStream is = null;
        try {
            urlConnection = (HttpConnection) Connector.open(url);
            urlConnection.setRequestMethod("GET");
            is = urlConnection.openInputStream();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return is;
    }

I saying that the case statement is wrong but this can be a good solution instead. If you choose to use the CASE statement, you have to make sure that at least one of the CASE condition is matched. Otherwise, you need to define an error handler to catch the error. Recall that you don’t have to do this with the IF statement.

SELECT if(hide = 0,FALSE,TRUE) col FROM tbl; #for BOOLEAN Value return

or

SELECT if(hide = 0,'FALSE','TRUE') col FROM tbl; #for string Value return

What I do in my Asp Net Core Api applications it is to create a class that extends from ObjectResult and provide many constructors to customize the content and the status code. Then all my Controller actions use one of the costructors as appropiate. You can take a look at my implementation at: https://github.com/melardev/AspNetCoreApiPaginatedCrud

and

https://github.com/melardev/ApiAspCoreEcommerce

here is how the class looks like(go to my repo for full code):

public class StatusCodeAndDtoWrapper : ObjectResult
{



    public StatusCodeAndDtoWrapper(AppResponse dto, int statusCode = 200) : base(dto)
    {
        StatusCode = statusCode;
    }

    private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, string message) : base(dto)
    {
        StatusCode = statusCode;
        if (dto.FullMessages == null)
            dto.FullMessages = new List<string>(1);
        dto.FullMessages.Add(message);
    }

    private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, ICollection<string> messages) : base(dto)
    {
        StatusCode = statusCode;
        dto.FullMessages = messages;
    }
}

Notice the base(dto) you replace dto by your object and you should be good to go.

For me the shortest way to get locale date and in correct format for input type="date" is this :

var d = new Date(); 
var today = d.getFullYear()+"-"+("0"+(d.getMonth()+1)).slice(-2)+"-"+("0"+d.getDate()).slice(-2);

Or this :

var d = new Date().toLocaleDateString().split('/');
var today = d[2]+"-"+("0"+d[0]).slice(-2)+"-"+("0"+d[1]).slice(-2);

Then just set the date input value :

$('#datePicker').val(today);

Why not use ES6?

 var myarray = ["item 1", "item 2", "item 3", "item 4"];_x000D_
 const [, ...rest] = myarray;_x000D_
 console.log(rest)

I may be a total noob but I had no clue I had to install npm-cli first. I had just assumed I already had it.

npm install --global vue-cli

You can use a little bit of Javascript to add and remove CSS classes of your navitems. For starters, create a CSS class that you're going to apply to the active element, name it ie: ".activeItem". Then, put a javascript function to each of your navigation buttons' onclick event which is going to add "activeItem" class to the one activated, and remove from the others...

It should look something like this: (untested!)

/*In your stylesheet*/
.activeItem{
   background-color:#999; /*make some difference for the active item here */
}


/*In your javascript*/
var prevItem = null;
function activateItem(t){
   if(prevItem != null){
      prevItem.className = prevItem.className.replace(/{\b}?activeItem/, "");
   }
   t.className += " activeItem";
   prevItem = t;
}

<!-- And then your markup -->
<div id='nav'>
<a href='#abouts' onClick="activateItem(this)">
<div class='navitem about'>
about
</div>
</a>
<a href='#workss' onClick="activateItem(this)">
<div class='navitem works'>
works
</div>
</a>
</div>

I had a similar problem, and never find anything on the web after excessive searching.

I reviewed the pom.xml file and in the dependencies I changed the scope of the <dependency> it: <scope>test</scope> to <scope>compile</scope> .

Previously I was using it only for tests but I change the project's structure and never knew I hve to change this.

test: This scope indicates that the dependency is not required for normal use of the application, and is only available for the test compilation and execution phases.

compile: This is the default scope, used if none is specified. Compile dependencies are available in all classpaths of a project. Furthermore, those dependencies are propagated to dependent projects.

Here is a reference from Apache Maven Docs: https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope

A quick one-liner.

list_a = [5,4,3,2,1]
list_b = [1,1.5,1.75,2,3,3.5,3.75,4,5]

Say you want list a to match list b.

orderedList =  sorted(list_a, key=lambda x: list_b.index(x))

This is helpful when needing to order a smaller list to values in larger. Assuming that the larger list contains all values in the smaller list, it can be done.

Well you can disable skype to use port 80. Click tools --> Options --> Advanced --> Connection and uncheck the appropriate checkbox.

Got it solved. I missed to delete the egg_info files of all previous Django versions. Removed them from /usr/local/lib/python2.7/dist-packages. Also from /usr/lib/python2.7/dist-packages (if any present here)

sudo pip freeze| grep Django
sudo pip show -f Django
sudo pip search Django | more +/^Django

All above commands should not show Django version to verify clean uninstallation.

You have to put java in lower case and you have to add .class!

java HelloWorld2.class

If you want to uninstall when connected to single device/emulator then use below command

adb uninstall <package name>

else with multiple devices then use below command

adb -s <device ID> uninstall <package name>

Check for session is new.

HttpSession session = request.getSession(false);
if (!session.isNew()) {
  // Session is valid
}
else {
  //Session has expired - redirect to login.jsp
}

As an addition and observation to the other useful answers, it's worth noticing that actually doing [:10] as slicing will return the first 10 elements of the list, not the last 10...

To get the last 10 you should do [-10:] instead (see here). This will help you avoid using order_by('-id') with the - to reverse the elements.

A simple function like below will help :

public string GetCurrentPageName() 
{ 
    string sPath = System.Web.HttpContext.Current.Request.Url.AbsolutePath; 
    System.IO.FileInfo oInfo = new System.IO.FileInfo(sPath); 
    string sRet = oInfo.Name; 
    return sRet; 
} 

The C++11 standard library contains a decent framework and a couple of serviceable generators, which is perfectly sufficient for homework assignments and off-the-cuff use.

However, for production-grade code you should know exactly what the specific properties of the various generators are before you use them, since all of them have their caveats. Also, none of them passes standard tests for PRNGs like TestU01, except for the ranlux generators if used with a generous luxury factor.

If you want solid, repeatable results then you have to bring your own generator.

If you want portability then you have to bring your own generator.

If you can live with restricted portability then you can use boost, or the C++11 framework in conjunction with your own generator(s).

More detail - including code for a simple yet fast generator of excellent quality and copious links - can be found in my answers to similar topics:

• General purpose random number generation
• Very fast uniform distribution random number generator

For professional uniform floating-point deviates there are two more issues to consider:

• open vs. half-open vs. closed range, i.e. (0,1), [0, 1) or [0,1]
• method of conversion from integral to floating-point (precision, speed)

Both are actually two sides of the same coin, as the method of conversion takes care of the inclusion/exclusion of 0 and 1. Here are three different methods for the half-open interval:

// exact values computed with bc

#define POW2_M32   2.3283064365386962890625e-010
#define POW2_M64   5.421010862427522170037264004349e-020

double random_double_a ()
{
   double lo = random_uint32() * POW2_M64;
   return lo + random_uint32() * POW2_M32;
}

double random_double_b ()
{
   return random_uint64() * POW2_M64;
}

double random_double_c ()
{
   return int64_t(random_uint64()) * POW2_M64 + 0.5;
}

(random_uint32() and random_uint64() are placeholders for your actual functions and would normally be passed as template parameters)

Method a demonstrates how to create a uniform deviate that is not biassed by excess precision for lower values; the code for 64-bit is not shown because it is simpler and just involves masking off 11 bits. The distribution is uniform for all functions but without this trick there would be more different values in the area closer to 0 than elsewhere (finer grid spacing due to the varying ulp).

Method c shows how to get a uniform deviate faster on certain popular platforms where the FPU knows only a signed 64-bit integral type. What you see most often is method b but there the compiler has to generate lots of extra code under the hood to preserve the unsigned semantics.

Mix and match these principles to create your own tailored solution.

All this is explained in Jürgen Doornik's excellent paper Conversion of High-Period Random Numbers to Floating Point.

Harry Martyrossian mentions in a comment on his own answer that the
Get-ItemPropertyValue cmdlet was introduced in Powershell v5, which solves the problem:

PS> Get-ItemPropertyValue 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion' 'ProgramFilesDir'
C:\Program Files

Alternatives for PowerShell v4-:

Here's an attempt to retain the efficiency while eliminating the need for repetition of the value name, which, however, is still a little cumbersome:

& { (Get-ItemProperty `
      -LiteralPath HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion `
      -Name $args `
    ).$args } 'ProgramFilesDir'

By using a script block, the value name can be passed in once as a parameter, and the parameter variable ($args) can then simply be used twice inside the block.

Alternatively, a simple helper function can ease the pain:

function Get-RegValue([String] $KeyPath, [String] $ValueName) {
  (Get-ItemProperty -LiteralPath $KeyPath -Name $ValueName).$ValueName
}

^{Note: All solutions above bypass the problem described in Ian Kemp's's answer - the need to use explicit quoting for certain value names when used as property names; e.g., .'15.0' - because the value names are passed as parameters and property access happens via a variable; e.g., .$ValueName}

As for the other answers:

• Andy Arismendi's helpful answer explains the annoyance with having to repeat the value name in order to get the value data efficiently.
• M Jeremy Carter's helpful answer is more convenient, but can be a performance pitfall for keys with a large number of values, because an object with a large number of properties must be constructed.

I know i'm too late for the answer but for people reading this I found a much easier way for doing it

myVariable = 'This string is supposed to be raw \'
print(r'%s' %myVariable)

The following snippet solved the issue for me:

class FigureWrapper(object):
    '''Frees underlying figure when it goes out of scope. 
    '''

    def __init__(self, figure):
        self._figure = figure

    def __del__(self):
        plt.close(self._figure)
        print("Figure removed")


# .....
    f, ax = plt.subplots(1, figsize=(20, 20))
    _wrapped_figure = FigureWrapper(f)

    ax.plot(...
    plt.savefig(...
# .....

When _wrapped_figure goes out of scope the runtime calls our __del__() method with plt.close() inside. It happens even if exception fires after _wrapped_figure constructor.

1. Go to project properties (Alt+F7)
2. Under Debugging, look to the right
3. There's an Environment field.
4. Add your relative path there (relative to vcproj folder) i.e. ..\some-framework\lib by appending PATH=%PATH%;$(ProjectDir)\some-framework\lib or prepending to the path PATH=C:\some-framework\lib;%PATH%
5. Hit F5 (debug) again and it should work.

Given

d = [[180.0], [173.8], [164.2], [156.5], [147.2], [138.2]]

and your specific question: How can I remove the brackets?

Using list comprehension :

new_d = [i[0] for i in d]

will give you this

[180.0, 173.8, 164.2, 156.5, 147.2, 138.2]

then you can access individual items with the appropriate index, e.g., new_d[0] will give you 180.0 etc which you can then use for math.

If you are going to have a collection of data, you will have some sort of bracket or parenthesis.

Note, this solution is aimed specifically at your question/problem, it doesn't provide a generalized solution. I.e., it will work for your case.

Your question almost spells the SQL for this:

DELETE FROM table WHERE id IN (1, 4, 6, 7)

This is the lifesaver code I found somewhere(sorry don't remember the origin). Add it to build.gradle (Module:app). You can replace the version to the relevant.

configurations.all {

    resolutionStrategy.eachDependency { DependencyResolveDetails details -
        def requested = details.requested

 if (requested.group == 'com.android.support') {

            if (!requested.name.startsWith("multidex")) {
                details.useVersion '27.1.1'
            }
        } else if (requested.group == "com.google.android.gms") {
            details.useVersion '15.0.0'
        } else if (requested.group == "com.google.firebase") {
            details.useVersion '15.0.0'
        }
    }
}

While JPA is the specification, Hibernate is the implementation provider that follows the rules dictated in the specification.

What about calculating the MD5 (or other) hash of sequential integers, then taking the first 8 characters.

i.e

MD5(1) = c4ca4238a0b923820dcc509a6f75849b => c4ca4238
MD5(2) = c81e728d9d4c2f636f067f89cc14862c => c81e728d
MD5(3) = eccbc87e4b5ce2fe28308fd9f2a7baf3 => eccbc87e

etc.

caveat: I have no idea how many you could allocate before a collision (but it would be a known and constant value).

edit: This is now an old answer, but I saw it again with time on my hands, so, from observation...

Chance of all numbers = 2.35%

Chance of all letters = 0.05%

First collision when MD5(82945) = "7b763dcb..." (same result as MD5(25302))

Below you can find my implementation of gradient descent for linear regression problem.

At first, you calculate gradient like X.T * (X * w - y) / N and update your current theta with this gradient simultaneously.

• X: feature matrix
• y: target values
• w: weights/values
• N: size of training set

Here is the python code:

import pandas as pd
import numpy as np
from matplotlib import pyplot as plt
import random

def generateSample(N, variance=100):
    X = np.matrix(range(N)).T + 1
    Y = np.matrix([random.random() * variance + i * 10 + 900 for i in range(len(X))]).T
    return X, Y

def fitModel_gradient(x, y):
    N = len(x)
    w = np.zeros((x.shape[1], 1))
    eta = 0.0001

    maxIteration = 100000
    for i in range(maxIteration):
        error = x * w - y
        gradient = x.T * error / N
        w = w - eta * gradient
    return w

def plotModel(x, y, w):
    plt.plot(x[:,1], y, "x")
    plt.plot(x[:,1], x * w, "r-")
    plt.show()

def test(N, variance, modelFunction):
    X, Y = generateSample(N, variance)
    X = np.hstack([np.matrix(np.ones(len(X))).T, X])
    w = modelFunction(X, Y)
    plotModel(X, Y, w)


test(50, 600, fitModel_gradient)
test(50, 1000, fitModel_gradient)
test(100, 200, fitModel_gradient)

This is your 2nd question: string.lowercase[ord('a')-97:ord('n')-97:2] because 97==ord('a') -- if you want to learn a bit you should figure out the rest yourself ;-)

FOO=bar
export FOO

You can use ord() function in Python for that.

For example, if you want to trigger 'a' key press, do as follows :

if cv2.waitKey(33) == ord('a'):
   print "pressed a"

See a sample code here: Drawing Histogram

UPDATE :

To find the key value for any key is to print the key value using a simple script as follows :

import cv2
img = cv2.imread('sof.jpg') # load a dummy image
while(1):
    cv2.imshow('img',img)
    k = cv2.waitKey(33)
    if k==27:    # Esc key to stop
        break
    elif k==-1:  # normally -1 returned,so don't print it
        continue
    else:
        print k # else print its value

With this code, I got following values :

Upkey : 2490368
DownKey : 2621440
LeftKey : 2424832
RightKey: 2555904
Space : 32
Delete : 3014656
...... # Continue yourself :)

Maybe something like this, where you could select more than one element if you'd like?

$("#number").each(function(){
    $(this).val(parseFloat($(this).val()).toFixed(2));
});

Did you forget the Background Property. The brush should be an ImageBrush whose ImageSource could be set to your image path.

<Grid>
    <Grid.Background>
        <ImageBrush ImageSource="/path/to/image.png" Stretch="UniformToFill"/>
    </Grid.Background>

    <...>
</Grid>

First, you can see if the user finished editing the text if the EditText loses focus or if the user presses the done button (this depends on your implementation and on what fits the best for you). Second, you can't get an EditText instance within the TextWatcher only if you have declared the EditText as an instance object. Even though you shouldn't edit the EditText within the TextWatcher because it is not safe.

EDIT:

To be able to get the EditText instance into your TextWatcher implementation, you should try something like this:

public class YourClass extends Activity {

    private EditText yourEditText;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);
        yourEditText = (EditText) findViewById(R.id.yourEditTextId);

        yourEditText.addTextChangedListener(new TextWatcher() {

            public void afterTextChanged(Editable s) {

                // you can call or do what you want with your EditText here

                // yourEditText... 
            }

            public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

            public void onTextChanged(CharSequence s, int start, int before, int count) {}
        });
    }
}

Note that the above sample might have some errors but I just wanted to show you an example.

By using the SqlCommand and its child collection of parameters all the pain of checking for sql injection is taken away from you and will be handled by these classes.

Here is an example, taken from one of the articles above:

private static void UpdateDemographics(Int32 customerID,
    string demoXml, string connectionString)
{
    // Update the demographics for a store, which is stored  
    // in an xml column.  
    string commandText = "UPDATE Sales.Store SET Demographics = @demographics "
        + "WHERE CustomerID = @ID;";

    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        SqlCommand command = new SqlCommand(commandText, connection);
        command.Parameters.Add("@ID", SqlDbType.Int);
        command.Parameters["@ID"].Value = customerID;

        // Use AddWithValue to assign Demographics. 
        // SQL Server will implicitly convert strings into XML.
        command.Parameters.AddWithValue("@demographics", demoXml);

        try
        {
            connection.Open();
            Int32 rowsAffected = command.ExecuteNonQuery();
            Console.WriteLine("RowsAffected: {0}", rowsAffected);
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }
}

Try change update="insTable:display" to update="display". I believe you cannot prefix the id with the form ID like that.

MySQL implicitly closed the database connection because the connection has been inactive for too long (34,247,052 milliseconds ˜ 9.5 hours). If your program then fetches a bad connection from the connection-pool that causes the MySQLNonTransientConnectionException: No operations allowed after connection closed.

MySQL suggests:

You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property autoReconnect=true to avoid this problem.

This is a side note if one still can't access localhost from another devices after following through the step above. This might be due to the apache ports.conf has been configured to serve locally (127.0.0.1) and not to outside.

check the following, (for ubuntu apache2)

  $ cat /etc/apache2/ports.conf

if the following is set,

NameVirtualHost *:80  
Listen 127.0.0.1:80  

then change it back to default value

NameVirtualHost *:80  
Listen 80  

You can groupby on cols 'A' and 'B' and call size and then reset_index and rename the generated column:

In [26]:

df1.groupby(['A','B']).size().reset_index().rename(columns={0:'count'})
Out[26]:
     A    B  count
0   no   no      1
1   no  yes      2
2  yes   no      4
3  yes  yes      3

update

A little explanation, by grouping on the 2 columns, this groups rows where A and B values are the same, we call size which returns the number of unique groups:

In[202]:
df1.groupby(['A','B']).size()

Out[202]: 
A    B  
no   no     1
     yes    2
yes  no     4
     yes    3
dtype: int64

So now to restore the grouped columns, we call reset_index:

In[203]:
df1.groupby(['A','B']).size().reset_index()

Out[203]: 
     A    B  0
0   no   no  1
1   no  yes  2
2  yes   no  4
3  yes  yes  3

This restores the indices but the size aggregation is turned into a generated column 0, so we have to rename this:

In[204]:
df1.groupby(['A','B']).size().reset_index().rename(columns={0:'count'})

Out[204]: 
     A    B  count
0   no   no      1
1   no  yes      2
2  yes   no      4
3  yes  yes      3

groupby does accept the arg as_index which we could have set to False so it doesn't make the grouped columns the index, but this generates a series and you'd still have to restore the indices and so on....:

In[205]:
df1.groupby(['A','B'], as_index=False).size()

Out[205]: 
A    B  
no   no     1
     yes    2
yes  no     4
     yes    3
dtype: int64

I could not get the keypress event to fire for the enter button, and scratched my head for some time, until I read the jQuery docs:

"The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except that modifier and non-printing keys such as Shift, Esc, and delete trigger keydown events but not keypress events." (https://api.jquery.com/keypress/)

I had to use the keyup or keydown event to catch a press of the enter button.

If you work on Linux you can try this:

setwd(system("pwd", intern = T) )

It works for me.

In order to set the value of integer variable we simply assign the value to it. eg g1val = 0 where as set keyword is used to assign value to object.

Sub test()

Dim g1val, g2val As Integer

  g1val = 0
  g2val = 0

    For i = 3 To 18

     If g1val > Cells(33, i).Value Then
        g1val = g1val
    Else
       g1val = Cells(33, i).Value
     End If

    Next i

    For j = 32 To 57
        If g2val > Cells(31, j).Value Then
           g2val = g2val
        Else
          g2val = Cells(31, j).Value
        End If
    Next j

End Sub

If you're open to a Perl solution...

perl -ane 'print "$F[0] $F[1]\n"' file

These command-line options are used:

• -n loop around every line of the input file, do not automatically print every line

• -a autosplit mode – split input lines into the @F array. Defaults to splitting on whitespace

• -e execute the following perl code

Alternatively you can use the classmethod decorator:

class A:
    @classmethod
    def get_classname(cls):
        return cls.__name__

    def use_classname(self):
        return self.get_classname()

Usage:

>>> A.get_classname()
'A'
>>> a = A()
>>> a.get_classname()
'A'
>>> a.use_classname()
'A'

try this one, seeker:

li+li { border-left: 1px solid #000000 }

this will affect only adjecent li elements

First check your listener is on or off. Go to net manager then Local -> service naming -> orcl. Then change your HOST NAME and put your PC name. Now go to LISTENER and change the HOST and put your PC name.

If you do not mind using an external library, Thumbnailator can perform scaling of BufferedImages.

Thumbnailator will take care of handling the Java 2D processing (such as using Graphics2D and setting appropriate rendering hints) so that a simple fluent API call can be used to resize images:

BufferedImage image = Thumbnails.of(originalImage).scale(2.0).asBufferedImage();

Although Thumbnailator, as its name implies, is geared toward shrinking images, it will do a decent job enlarging images as well, using bilinear interpolation in its default resizer implementation.

Disclaimer: I am the maintainer of the Thumbnailator library.

Try out below code snippet:

 var list = [];
 var text;

function update() {
    console.log(list);    

    for (var i = 0; i < list.length; i++) {
       console.log( i );
       var letters;
       var ul = document.getElementById("list");
       var li = document.createElement("li");

       li.appendChild(document.createTextNode(list[i]));
       ul.appendChild(li);

       letters += "<li>"  + list[i] + "</li>";
    }

 document.getElementById("list").innerHTML = letters;

}

function myFunction() {
    text = prompt("enter TODO");  
    list.push(text);
    update();
}   

This is because a DATE column in Oracle also contains a time part. The result of the to_date() function is a date with the time set to 00:00:00 and thus it probably doesn't match any rows in the table.

You should use:

SELECT EMP_NAME, DEPT
FROM EMPLOYEE
WHERE trunc(TIME_CREATED) = TO_DATE('26/JAN/2011','dd/mon/yyyy')

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

import org.springframework.core.io.ClassPathResource;

...

File folder = new ClassPathResource("sql").getFile();
File[] listOfFiles = folder.listFiles();

It is worth noting that this will limit your deployment options, ClassPathResource.getFile() only works if the container has exploded (unzipped) your war file.

column_obj != None will produce a IS NOT NULL constraint:

In a column context, produces the clause a != b. If the target is None, produces a IS NOT NULL.

or use isnot() (new in 0.7.9):

Implement the IS NOT operator.

Normally, IS NOT is generated automatically when comparing to a value of None, which resolves to NULL. However, explicit usage of IS NOT may be desirable if comparing to boolean values on certain platforms.

Demo:

>>> from sqlalchemy.sql import column
>>> column('YourColumn') != None
<sqlalchemy.sql.elements.BinaryExpression object at 0x10c8d8b90>
>>> str(column('YourColumn') != None)
'"YourColumn" IS NOT NULL'
>>> column('YourColumn').isnot(None)
<sqlalchemy.sql.elements.BinaryExpression object at 0x104603850>
>>> str(column('YourColumn').isnot(None))
'"YourColumn" IS NOT NULL'

Non of these worked for me... when I converted the timestamp back it's 4 years off.

This worked perfectly: =(A2-DATE(1970,1,1))*86400

Adding to Dmitri Chebotarev Answer,

If you want to alter multiple columns at a time , you can do it like below

DB::statement('
     ALTER TABLE `events` 
            MODIFY `event_date` DATE NOT NULL,
            MODIFY `event_start_time` TIME NOT NULL,
            MODIFY `event_end_time` TIME NOT NULL;
');

class test
{
public static void useServerPath(string path)
{
   if (File.Exists(path)
{
 \\...... do whatever you wabt
}
else
{
\\.....
}
}

Now when you call the method from the codebehind

for example :

protected void BtAtualizacao_Click(object sender, EventArgs e)
        {
             string path = Server.MapPath("Folder") + "\\anifile.txt";

            test.useServerPath(path);
}

in this way your code is to simple and with one method u can use multiple path for each call :)

You can simply use:

ps -o args= -f -p ProcessPid

I tried a few of the tricks listed here without any luck. Looks like something was getting cached by my terminal emulator (iTerm2) or session. The issue went away when I ran the command from a fresh terminal tab.

What do you want to do with the attribute? Is it an html attribute or something of your own?

Most of the time you can simply address it as a property: want to set a title on an element? element.title = "foo" will do it.

For your own custom JS attributes the DOM is naturally extensible (aka expando=true), the simple upshot of which is that you can do element.myCustomFlag = foo and subsequently read it without issue.

This error occurs due to multiple installations of mysql. Run the command:

ps -A|grep mysql

Kill the process by using:

sudo pkill mysql

and then run command:

ps -A|grep mysqld

Also Kill this process by running:

sudo pkill mysqld

Now you are fully set just run the following commands:

service mysql restart
mysql -u root -p

Have very well working mysql again

Perhaps you can try to BeginInvoke a delegate pointing to your method like so:

    delegate string SynchOperation(string value);

    class Program
    {
        static void Main(string[] args)
        {
            BeginTheSynchronousOperation(CallbackOperation, "my value");
            Console.ReadLine();
        }

        static void BeginTheSynchronousOperation(AsyncCallback callback, string value)
        {
            SynchOperation op = new SynchOperation(SynchronousOperation);
            op.BeginInvoke(value, callback, op);
        }

        static string SynchronousOperation(string value)
        {
            Thread.Sleep(10000);
            return value;
        }

        static void CallbackOperation(IAsyncResult result)
        {
            // get your delegate
            var ar = result.AsyncState as SynchOperation;
            // end invoke and get value
            var returned = ar.EndInvoke(result);

            Console.WriteLine(returned);
        }
    }

Then use the value in the method you sent as AsyncCallback to continue..

Part 1 - height

As starblue says, height is just recursive. In pseudo-code:

height(node) = max(height(node.L), height(node.R)) + 1

Now height could be defined in two ways. It could be the number of nodes in the path from the root to that node, or it could be the number of links. According to the page you referenced, the most common definition is for the number of links. In which case the complete pseudo code would be:

height(node): 
   if node == null:
        return -1
   else:
        return max(height(node.L), height(node.R)) + 1

If you wanted the number of nodes the code would be:

height(node): 
   if node == null:
        return 0
   else:
        return max(height(node.L), height(node.R)) + 1

Either way, the rebalancing algorithm I think should work the same.

However, your tree will be much more efficient (O(ln(n))) if you store and update height information in the tree, rather than calculating it each time. (O(n))

Part 2 - balancing

When it says "If the balance factor of R is 1", it is talking about the balance factor of the right branch, when the balance factor at the top is 2. It is telling you how to choose whether to do a single rotation or a double rotation. In (python like) Pseudo-code:

if balance factor(top) = 2: // right is imbalanced
     if balance factor(R) = 1: // 
          do a left rotation
     else if balance factor(R) = -1:
          do a double rotation
else: // must be -2, left is imbalanced
     if balance factor(L) = 1: // 
          do a left rotation
     else if balance factor(L) = -1:
          do a double rotation

I hope this makes sense

nvarchar is going to have significant overhead in memory, storage, working set and indexing, so if the specs dictate that it really will never be necessary, don't bother.

I would not have a hard and fast "always nvarchar" rule because it can be a complete waste in many situations - particularly ETL from ASCII/EBCDIC or identifiers and code columns which are often keys and foreign keys.

On the other hand, there are plenty of cases of columns, where I would be sure to ask this question early and if I didn't get a hard and fast answer immediately, I would make the column nvarchar.

Per the jQuery documentation, try this:

$('input[inputName\\[\\]=someValue]')

[EDIT] However, I'm not sure that's the right syntax for your selector. You probably want:

$('input[name="inputName[]"][value="someValue"]')

The idea is that the response body gives you a page that links you to the thing:

201 Created

The 201 (Created) status code indicates that the request has been fulfilled and has resulted in one or more new resources being created. The primary resource created by the request is identified by either a Location header field in the response or, if no Location field is received, by the effective request URI.

This means that you would include a Location in the response header that gives the URL of where you can find the newly created thing:

HTTP/1.1 201 Created
Date: Sat, 02 Apr 2016 12:22:40 GMT
Location: http://stackoverflow.com/a/36373586/12597

Response body

They then go on to mention what you should include in the response body:

The 201 response payload typically describes and links to the resource(s) created.

For the human using the browser, you give them something they can look at, and click, to get to their newly created resource:

If the page will only be used by a robot, the it makes sense to have the response be computer readable:

      <resource>http://stackoverflow.com/a/1962757/12597</resource>
   </additional>
</createdResource>

Or, if you prefer:

      "http://stackoverflow.com/a/36373586/12597"
   ]
}

The response is entirely up to you; it's arbitrarily what you'd like.

Cache friendly

Finally there's the optimization that I can pre-cache the created resource (because I already have the content; I just uploaded it). The server can return a date or ETag which I can store with the content I just uploaded:

See Section 7.2 for a discussion of the meaning and purpose of validator header fields, such as ETag and Last-Modified, in a 201 response.

And ETag s are purely arbitrary values. Having them be different when a resource changes (and caches need to be updated) is all that matters. The ETag is usually a hash (e.g. SHA2). But it can be a database rowversion, or an incrementing revision number. Anything that will change when the thing changes.

I am not sure if I see this option here. You can just create a /folder in your repository and use it directly:

[a relative link](/folder/myrelativefile.md)

No blob or tree or repository name is needed, and it works like a charm.

Adding this to your WebSecurityConfiguration class should do the trick.

@Configuration
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/v2/api-docs",
                                   "/configuration/ui",
                                   "/swagger-resources/**",
                                   "/configuration/security",
                                   "/swagger-ui.html",
                                   "/webjars/**");
    }

You can customize by yourself according to your requirement.

It should be $_COOKIE['name'], not $_COOKIE('name')

$_COOKIE is an array, not a function.

If you cannot find the process locking the table (cause it is alreay dead), it may be a thread still cleaning up like this

section TRANSACTION of

show engine innodb status;

at the end

---TRANSACTION 1135701157, ACTIVE 6768 sec
MySQL thread id 5208136, OS thread handle 0x7f2982e91700, query id 882213399 xxxIPxxx 82.235.36.49 my_user cleaning up

as mentionned in a comment in Clear transaction deadlock?

you can try killing the transaction thread directly, here with

 KILL 5208136;

worked for me.

Try using the success() call back

$http.get('/Documents/DocumentsList/' + caseId).success(function (result) {
    $scope.Documents = result;
});

But now since Documents is an array and not a promise, remove the ()

<li ng-repeat="document in Documents" ng-class="IsFiltered(document.Filtered)"> <span>
           <input type="checkbox" name="docChecked" id="doc_{{document.Id}}" ng-model="document.Filtered" />
        </span>
 <span>{{document.Name}}</span>

</li>

Verify(a).aFunc(eq(b))

In pseudocode:

When in the instance a - a function named aFunc is called.

Verify this call got an argument which is equal to b.

First of all, if you want it displayed on a PHP form, the medium is HTML and so a new line will be rendered with the <br /> tag. Check the source HTML of the page - you may possibly have the new line rendered just as a line break, in which case your problem is simply one of translating the text for output to a web browser.

None of the other answers worked for me. I fixed my error by changing the web project's output path. I had had it set to bin\debug but the web project doesn't work unless the output path is set to simply "bin"

As of npm@5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use npm cache verify instead. On the other hand, if you're debugging an issue with the installer, you can use npm install --cache /tmp/empty-cache to use a temporary cache instead of nuking the actual one.

If you're sure you want to delete the entire cache, rerun:

npm cache clean --force

A complete log of this run can be found in /Users/USERNAME/.npm/_logs/2019-01-08T21_29_30_811Z-debug.log.

We can always measure time taken by any function by simple date object.

var start = +new Date();  // log start timestamp
function1();
var end =  +new Date();  // log end timestamp
var diff = end - start;

Indeed, just as commented by Tim Williams, the way to make it work is pre-formatting as text. Thus, to do it all via VBA, just do that:

Cells(1, 1).NumberFormat = "@"
Cells(1, 1).Value = "1234,56"

In addition to Alexis C's answer, If you are working with an array list, in which you are not sure whether the element you are searching for exists, use this.

Integer a = list.stream()
                .peek(num -> System.out.println("will filter " + num))
                .filter(x -> x > 5)
                .findFirst()
                .orElse(null);

Then you could simply check whether a is null.

You can tell Git what to do with your index (set of files that will become the next commit) and working directory when performing git reset by using one of the parameters:

--soft: Only commits will be reseted, while Index and the working directory are not altered.

--mixed: This will reset the index to match the HEAD, while working directory will not be touched. All the changes will stay in the working directory and appear as modified.

--hard: It resets everything (commits, index, working directory) to match the HEAD.

In your case, I would use git reset --soft to keep your modified changes in Index and working directory. Be sure to check this out for a more detailed explanation.

Generally speaking, you can update your index mapping using the put mapping api (reference here) :

curl -XPUT 'http://localhost:9200/advert_index/_mapping/advert_type' -d '
{
    "advert_type" : {
        "properties" : {

          //your new mapping properties

        }
    }
}
'

It's especially useful for adding new fields. However, in your case, you will try to change the location type, which will cause a conflict and prevent the new mapping from being used.

You could use the put mapping api to add another property containing the location as a lat/lon array, but you won't be able to update the previous location field itself.

Finally, you will have to reindex your data for your new mapping to be taken into account.

The best solution would really be to create a new index.

If your problem with creating another index is downtime, you should take a look at aliases to make things go smoothly.
