It can be simply overcome by setting on Project Structure. You just need to select the right path for related version of JDK. Select new on dependencies tab, and choose the path. It's done!

If you are still finding that the default wrong Java version (1.7) is being used instead of your Java home directory, then all you need to do is simply change the order of your PATH variable to set JAVA_HOME\bin before your Windows directory in your PATH variable, save it and restart cygwin. Test it out to make sure everything will work fine. It should not have any adverse effect because you want your own Java version to override the default which comes with Windows. Good luck!

If you have set all PATH variables correctly after installation, just restart it.

I had the same problem, I had also installed new Windows7 OS then I upgraded it to Win 10. Then i started setup necessary tools like IntelliJ, Java jdk,jre, eclipse so on. In cmd, java -version worked but javac compiler got unrecognized. I checked and all good, the files in the folders, path are correct and so on.

I restarted and checked it again in cmd ,it worked.

The error "Class names are only accepted if annotation processing is explicitly requested" can be caused by one or more of the following:

1. Not using the .java extension for your java file when compiling.
2. Improper capitalization of the .java extension (i.e. .Java) when compiling.
3. Any other typo in the .java extension when compiling.
4. When compiling and running at the same time, forgetting to use '&&' to concatenate the two commands (i.e. javac Hangman.java java Hangman). It took me like 30 minutes to figure this out, which I noticed by running the compilation and the running the program separately, which of course worked perfectly fine.

This may not be the complete list of causes to this error, but these are the causes that I am aware of so far.

Try the following:

javac file1.java file2.java

To find the env vars dialog in Windows 10:

Right Click Start
>>  Click Control Panel  (Or you may have System in the list)
>>  Click System
>>  Click Advanced system settings
>>  Go to the Advanced Tab
>>  Click the "Environment Variables..." button at the bottom of that dialog page.

hey I think that you just copy your compiled class files and copy the jre folder and make the following as the content of the batch file and save all together any windows machine and just double click

@echo
setpath d:\jre
d:
cd myprogfolder
java myprogram

The BOM is generated by, say, File.WriteAllText() or StreamWriter when you don't specify an Encoding. The default is to use the UTF8 encoding and generate a BOM. You can tell the java compiler about this with its -encoding command line option.

The path of least resistance is to avoid generating the BOM. Do so by specifying System.Text.Encoding.Default, that will write the file with the characters in the default code page of your operating system and doesn't write a BOM. Use the File.WriteAllText(String, String, Encoding) overload or the StreamWriter(String, Boolean, Encoding) constructor.

Just make sure that the file you create doesn't get compiled by a machine in another corner of the world. It will produce mojibake.

1. Go to my computer;
2. Right click properties;
3. Go to advanced system settings;
4. Go to environment variables;
5. In user variables for user click on new(top new button, not on system variables);
6. Set variable name as: Path
7. Set the value of that variable to: C:\Program Files\Java\jdk1.7.0_76\bin
8. Click ok;
9. Click ok;
10. Click ok.

Now you're set. Type javac in cmd. All javac options will be displayed.

Both source and target should be specified. I recommend providing ant defaults, that way you do not need to specify source/target attribute for every javac task:

<property name="ant.build.javac.source" value="1.5"/>
<property name="ant.build.javac.target" value="1.5"/>

See Java cross-compiling notes for more information.

Windows solution: Assuming all files contained in sub-directory 'src', and you want to compile them to 'bin'.

for /r src %i in (*.java) do javac %i -sourcepath src -d bin

If src contains a .java file immediately below it then this is faster

javac src\\*.java -d bin

Most certainly, export JAVA_HOME=/usr/bin/java is the culprit. This env var should point to the JDK or JRE installation directory. Googling shows that the best option for MacOS X seems to be export JAVA_HOME=/Library/Java/Home.

Is the javac executable in a directory that is part of your PATH?

I don't know the CentOS equivalent of the Windows path but if you cd to the java sdk directory and run ./javac does anything happen?

If java command is working and getting problem with javac. then first check in jdk's bin directory javac.exe file is there or not. If javac.exe file is exist then set JAVA_HOME as System variable.

I just had to do this to get this to work on windows 7 64.

Open up a command prompt (cmd.exe) and type:

set CLASSPATH=C:\Program Files\Java\jdk1.7.0_01\bin

Make sure you reopen all running command prompt Windows to get the environment variable updated as well.

None of the current answers helped me here. We were getting something like:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:
    #.#.#:compile (default-compile) on project Streaming_Test: Compilation failure
[ERROR] Unable to locate the Javac Compiler in:
[ERROR] /opt/java/J7.0/../lib/tools.jar

This happens because the Java installation has determined that it is a JRE installation. It's expecting there to be JDK stuff above the JRE subdirectory, hence the ../lib in the path. Our tools.jar is in $JAVA_HOME/lib/tools.jar not in $JAVA_HOME/../lib/tools.jar.

Unfortunately, we do not have an option to install a JDK on our OS (don't ask) so that wasn't an option. I fixed the problem by adding the following to the maven pom.xml:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
      <fork>true</fork>  <!-- not sure if this is also needed -->
      <executable>${JAVA_HOME}/bin/javac</executable>
      <!--        ^^^^^^^^^^^^^^^^^^^^^^ -->
    </configuration>
  </plugin>

By pointing the executable to the right place this at least got past our compilation failures.

Use <property name="build.sysclasspath" value="last"/> in your build.xml file

For more details search includeAntRuntime in Ant javac

Other possible values could be found here

javac command does not follow a recursive compilation process, so you have either specify each directory when running command, or provide a text file with directories you want to include:

javac -classpath "${CLASSPATH}" @java_sources.txt

The following syntax fixes it for you:

curl -v -F key1=value1 -F upload=@localfilename URL

Have you added the dll into your project references list? If not right click on the project "References" folder and selecet "Add Reference" then use browse to locate your science.dll, select it and click ok.

edit

I can't see the image of your VS instance that some people are referring to and I note that you now say that it works in Net4.0 and VS2010.

VS2008 projects support NET 3.5 by default. I expect that is the problem as your DLL may be NET 4.0 compliant but not NET 3.5.

One line solution

var id = request.Headers.GetValues("MyCustomID").FirstOrDefault();

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

Actually Java supports 4 methods to parse XML out of the box:

DOM Parser/Builder: The whole XML structure is loaded into memory and you can use the well known DOM methods to work with it. DOM also allows you to write to the document with Xslt transformations. Example:

public static void parse() throws ParserConfigurationException, IOException, SAXException {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setValidating(true);
    factory.setIgnoringElementContentWhitespace(true);
    DocumentBuilder builder = factory.newDocumentBuilder();
    File file = new File("test.xml");
    Document doc = builder.parse(file);
    // Do something with the document here.
}

SAX Parser: Solely to read a XML document. The Sax parser runs through the document and calls callback methods of the user. There are methods for start/end of a document, element and so on. They're defined in org.xml.sax.ContentHandler and there's an empty helper class DefaultHandler.

public static void parse() throws ParserConfigurationException, SAXException {
    SAXParserFactory factory = SAXParserFactory.newInstance();
    factory.setValidating(true);
    SAXParser saxParser = factory.newSAXParser();
    File file = new File("test.xml");
    saxParser.parse(file, new ElementHandler());    // specify handler
}

StAx Reader/Writer: This works with a datastream oriented interface. The program asks for the next element when it's ready just like a cursor/iterator. You can also create documents with it. Read document:

public static void parse() throws XMLStreamException, IOException {
    try (FileInputStream fis = new FileInputStream("test.xml")) {
        XMLInputFactory xmlInFact = XMLInputFactory.newInstance();
        XMLStreamReader reader = xmlInFact.createXMLStreamReader(fis);
        while(reader.hasNext()) {
            reader.next(); // do something here
        }
    }
}

Write document:

public static void parse() throws XMLStreamException, IOException {
    try (FileOutputStream fos = new FileOutputStream("test.xml")){
        XMLOutputFactory xmlOutFact = XMLOutputFactory.newInstance();
        XMLStreamWriter writer = xmlOutFact.createXMLStreamWriter(fos);
        writer.writeStartDocument();
        writer.writeStartElement("test");
        // write stuff
        writer.writeEndElement();
    }
}

JAXB: The newest implementation to read XML documents: Is part of Java 6 in v2. This allows us to serialize java objects from a document. You read the document with a class that implements a interface to javax.xml.bind.Unmarshaller (you get a class for this from JAXBContext.newInstance). The context has to be initialized with the used classes, but you just have to specify the root classes and don't have to worry about static referenced classes. You use annotations to specify which classes should be elements (@XmlRootElement) and which fields are elements(@XmlElement) or attributes (@XmlAttribute, what a surprise!)

public static void parse() throws JAXBException, IOException {
    try (FileInputStream adrFile = new FileInputStream("test")) {
        JAXBContext ctx = JAXBContext.newInstance(RootElementClass.class);
        Unmarshaller um = ctx.createUnmarshaller();
        RootElementClass rootElement = (RootElementClass) um.unmarshal(adrFile);
    }
}

Write document:

public static void parse(RootElementClass out) throws IOException, JAXBException {
    try (FileOutputStream adrFile = new FileOutputStream("test.xml")) {
        JAXBContext ctx = JAXBContext.newInstance(RootElementClass.class);
        Marshaller ma = ctx.createMarshaller();
        ma.marshal(out, adrFile);
    }
}

Examples shamelessly copied from some old lecture slides ;-)

Edit: About "which API should I use?". Well it depends - not all APIs have the same capabilities as you see, but if you have control over the classes you use to map the XML document JAXB is my personal favorite, really elegant and simple solution (though I haven't used it for really large documents, it could get a bit complex). SAX is pretty easy to use too and just stay away from DOM if you don't have a really good reason to use it - old, clunky API in my opinion. I don't think there are any modern 3rd party libraries that feature anything especially useful that's missing from the STL and the standard libraries have the usual advantages of being extremely well tested, documented and stable.

Run these commands in terminal and everything will work fine:

sudo /etc/init.d/apache2 stop   
sudo /opt/lampp/lampp start

This is normal if you see it. Since it is the first virtual host entry, it will show local host.

Let’s say for example you didn't want that page to show. All you want to show is the "Apache, it works" page, so you would make a vhost entry before mysite.local as local host and point it to the "it works" page.

But this is normal. I had this problem before, so don't worry!

C++ has two kinds of enum:

1. enum classes
2. Plain enums

Here are a couple of examples on how to declare them:

 enum class Color { red, green, blue }; // enum class
 enum Animal { dog, cat, bird, human }; // plain enum 

What is the difference between the two?

• enum classes - enumerator names are local to the enum and their values do not implicitly convert to other types (like another enum or int)

• Plain enums - where enumerator names are in the same scope as the enum and their values implicitly convert to integers and other types

Example:

enum Color { red, green, blue };                    // plain enum 
enum Card { red_card, green_card, yellow_card };    // another plain enum 
enum class Animal { dog, deer, cat, bird, human };  // enum class
enum class Mammal { kangaroo, deer, human };        // another enum class

void fun() {

    // examples of bad use of plain enums:
    Color color = Color::red;
    Card card = Card::green_card;

    int num = color;    // no problem

    if (color == Card::red_card) // no problem (bad)
        cout << "bad" << endl;

    if (card == Color::green)   // no problem (bad)
        cout << "bad" << endl;

    // examples of good use of enum classes (safe)
    Animal a = Animal::deer;
    Mammal m = Mammal::deer;

    int num2 = a;   // error
    if (m == a)         // error (good)
        cout << "bad" << endl;

    if (a == Mammal::deer) // error (good)
        cout << "bad" << endl;

}

Conclusion:

enum classes should be preferred because they cause fewer surprises that could potentially lead to bugs.

For my specific case it was a service reference another developer merged into the main branch. Which was perfectly fine except syntax highlight failed to resolve the generated service class and source was all red underlined. Cleaning, rebuilding, restarting did nothing.

All I had to do was refresh the service reference and VS managed to put the pieces together behind the scenes. No changes in the source code or generated files.

For the Android library projects, I do it as in the attached screenshot:

Right click the project, select Properties->Android and in the library section click Add. From here you can select the available libraries.

If you are importing a jar file, then importing them as jar or external jar, as other posters posted would work. I prefer to copy/paste jar file in the libs folder (create one if it doesn't exist) and then import as jar.

The non-category plugin did not work for me.

For Multisite WordPress the following works:

1. Go to network admin sites;
2. Open site under \;
3. Go to settings;
4. Under permalinks structure type /%category%/%postname%/. This will display your url as www.domainname.com/categoryname/postname;
5. Now go to your site dashboard (not network dashboard);
6. Open settings;
7. Open permalink. Do not save (the permalink will show uneditable field as yourdoamainname/blog/. Ignore it. If you save now the work you did in step 4 will be overwritten. This step of opening permalink page but not saving in needed to update the database.

To answer your question, let's assume that you are interested in a specific angular version and NOT in a specific angular-cli version (angular-cli is just a tool after all).

A reasonnable move is to keep your angular-cli version alligned with your angular version, otherwise you risk to stumble into incompatibilities issues. So getting the correct angular-cli version will lead you to getting the desired angular version.

From that assumption, your question is not about angular-cli, but about npm.

Here is the way to go:

[STEP 0 - OPTIONAL] If you're not sure of the angular-cli version installed in your environment, uninstall it.

npm uninstall -g @angular/cli

Then, run (--force flag might be required)

npm cache clean

or, if you're using npm > 5.

npm cache verify

[STEP 1] Install an angular-cli specific version

npm install -g @angular/[email protected]

[STEP 2] Create a project

ng new you-app-name

The resulting white app will be created in the desired angular version.

NOTE: I have not found any page displaying the compatibility matrix of angular and angular-cli. So I guess the only way to know what angular-cli version should be installed is to try various versions, create a new project and checkout the package.json to see which angular version is used.

If you are using Django >= 1.9 with Postgres you can make use of ArrayField advantages

A field for storing lists of data. Most field types can be used, you simply pass another field instance as the base_field. You may also specify a size. ArrayField can be nested to store multi-dimensional arrays.

It is also possible to nest array fields:

from django.contrib.postgres.fields import ArrayField
from django.db import models

class ChessBoard(models.Model):
    board = ArrayField(
        ArrayField(
            models.CharField(max_length=10, blank=True),
            size=8,
        ),
        size=8,
    )

As @thane-brimhall mentioned it is also possible to query elements directly. Documentation reference

I had also warnings in Google Dev-Tools and I added only bootstrap.min.css.map file in the same folder, where bootstrap.min.css is.

I have now no warnings more and You can find more Explanation here: https://github.com/twbs/bootstrap#whats-included

I hope, I answered your Question.

Here is a clean way to disable and enable submit button:

<input type="submit" name="sendNewSms" class="inputButton" id="sendNewSms" value=" Send " />
<input type="checkbox" id="disableBtn" />

var submit = document.getElementById('sendNewSms'),
    checkbox = document.getElementById('disableBtn'),
    disableSubmit = function(e) {
        submit.disabled = this.checked
    };

checkbox.addEventListener('change', disableSubmit);

Here is a fiddle of it in action: http://jsfiddle.net/sYNj7/

As much as the most of the answers here are valid, I need to tell that your solution is also how the actual Java API developers do it. (Either Josh Bloch or Neal Gafter)

Here is an extract from openJDK, ArrayList class:

public Object clone() {
    try {
        ArrayList<?> v = (ArrayList<?>) super.clone();
        v.elementData = Arrays.copyOf(elementData, size);
        v.modCount = 0;
        return v;
    } catch (CloneNotSupportedException e) {
        // this shouldn't happen, since we are Cloneable
        throw new InternalError(e);
    }
}

As you have noticed and others mentioned, CloneNotSupportedException has almost no chance to be thrown if you declared that you implement the Cloneable interface.

Also, there is no need for you to override the method if you don't do anything new in the overridden method. You only need to override it when you need to do extra operations on the object or you need to make it public.

Ultimately, it is still best to avoid it and do it using some other way.

You could do this:

SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%MyColumn%'
ORDER BY schema_name, table_name;

Add latest gradle version properly in build.gradle file and latest distributionUrl in gradle-wrapper.properties file. [refer https://developer.android.com/studio/releases/gradle-plugin.html for the latest gradle version of android studio]

Make sure network connectivity is proper [ Network connection should not block upgrading gradle in android studio]. After gradle upgrade android studio will prompt alert to accept/decline certificate and we should accept the certificate.

import os
import sys

Assuming test.sh is the shell script that you would want to execute

os.system("sh test.sh")

In Visual Studio UML sequence this can also be described as fragments which is nicely documented here: https://msdn.microsoft.com/en-us/library/dd465153.aspx

Replace this :

$('#subscription_order_form').submit(function(e){
  e.preventDefault();
});

with this:

$('#subscription_order_form').on('keydown', function(e){
    if (e.which===13) e.preventDefault();
});

FIDDLE

That will prevent the form from submitting when Enter key is pressed as it prevents the default action of the key, but the form will submit normally on click.

Assuming you're using jQuery..

var input = '19 51 2.108997\n20 47 2.1089';
var lines = input.split('\n');
var output = '';
$.each(lines, function(key, line) {
    var parts = line.split(' ');
    output += '<span>' + parts[0] + ' ' + parts[1] + '</span><span>' + parts[2] + '</span>\n';
});
$(output).appendTo('body');

simplest thing to do; just add:

app:navigationIcon="@drawable/ic_action_navigation_menu">

to the <android.support.v7.widget.Toolbar tag

where @drawable/ic_action_navigation_menu is the name of icon

POCO is simply an object that does not take a dependency on an external framework. It is PLAIN.

Whether a POCO has behaviour or not it's immaterial.

A DTO may be POCO as may a domain object (which would typically be rich in behaviour).

Typically DTOs are more likely to take dependencies on external frameworks (eg. attributes) for serialisation purposes as typically they exit at the boundary of a system.

In typical Onion style architectures (often used within a broadly DDD approach) the domain layer is placed at the centre and so its objects should not, at this point, have dependencies outside of that layer.

You should enable the unicode strings feature, and this is the default if you use v5.14;

You should not really use unicode identifiers esp. for foreign code via utf8 as they are insecure in perl5, only cperl got that right. See e.g. http://perl11.org/blog/unicode-identifiers.html

Regarding utf8 for your filehandles/streams: You need decide by yourself the encoding of your external data. A library cannot know that, and since not even libc supports utf8, proper utf8 data is rare. There's more wtf8, the windows aberration of utf8 around.

BTW: Moose is not really "Modern Perl", they just hijacked the name. Moose is perfect Larry Wall-style postmodern perl mixed with Bjarne Stroustrup-style everything goes, with an eclectic aberration of proper perl6 syntax, e.g. using strings for variable names, horrible fields syntax, and a very immature naive implementation which is 10x slower than a proper implementation. cperl and perl6 are the true modern perls, where form follows function, and the implementation is reduced and optimized.

The difference is that variant 1 forces you to use an ArrayList while variant 2 only guarantees you have anything that implements List<String>.

Later on you could change that to List<String> arrayList = new LinkedList<String>(); without much hassle. Variant 1 might require you to change not only that line but other parts as well if they rely on working with an ArrayList<String>.

Thus I'd use List<String> in almost any case, except when I'd need to call the additional methods that ArrayList provides (which was never the case so far): ensureCapacity(int) and trimToSize().

For multiple plots in a single pdf file you can use PdfPages

In the plotGraph function you should return the figure and than call savefig of the figure object.

------ plotting module ------

def plotGraph(X,Y):
      fig = plt.figure()
      ### Plotting arrangements ###
      return fig

------ plotting module ------

----- mainModule ----

from matplotlib.backends.backend_pdf import PdfPages

plot1 = plotGraph(tempDLstats, tempDLlabels)
plot2 = plotGraph(tempDLstats_1, tempDLlabels_1)
plot3 = plotGraph(tempDLstats_2, tempDLlabels_2)

pp = PdfPages('foo.pdf')
pp.savefig(plot1)
pp.savefig(plot2)
pp.savefig(plot3)
pp.close()

You should use Ctrl+shift+enter when using the =SUM(VLOOKUP(A9,A1:D5,{2,3,4,},FALSE)) that results in {=SUM(VLOOKUP(A9,A1:D5,{2,3,4,},FALSE))} en also works.

The answer posted by @schellack is perfect for most scenarios, but I wanted Beyond Compare to simulate the '2 Way merge with a result panel' view that Visual Studio uses in its own merge window.

This config hides the middle panel (which is unused in most cases AFAIK).

I think Semaphore is what you are looking for, it will block the main process after counting down to 0. Sample code:

from multiprocessing import Process
from multiprocessing import Semaphore
import time

def f(name, sema):
    print('process {} starting doing business'.format(name))
    # simulate a time-consuming task by sleeping
    time.sleep(5)
    # `release` will add 1 to `sema`, allowing other 
    # processes blocked on it to continue
    sema.release()

if __name__ == '__main__':
    concurrency = 20
    total_task_num = 1000
    sema = Semaphore(concurrency)
    all_processes = []
    for i in range(total_task_num):
        # once 20 processes are running, the following `acquire` call
        # will block the main process since `sema` has been reduced
        # to 0. This loop will continue only after one or more 
        # previously created processes complete.
        sema.acquire()
        p = Process(target=f, args=(i, sema))
        all_processes.append(p)
        p.start()

    # inside main process, wait for all processes to finish
    for p in all_processes:
        p.join()

The following code is more structured since it acquires and releases sema in the same function. However, it will consume too much resources if total_task_num is very large:

from multiprocessing import Process
from multiprocessing import Semaphore
import time

def f(name, sema):
    print('process {} starting doing business'.format(name))
    # `sema` is acquired and released in the same
    # block of code here, making code more readable,
    # but may lead to problem.
    sema.acquire()
    time.sleep(5)
    sema.release()

if __name__ == '__main__':
    concurrency = 20
    total_task_num = 1000
    sema = Semaphore(concurrency)
    all_processes = []
    for i in range(total_task_num):
        p = Process(target=f, args=(i, sema))
        all_processes.append(p)
        # the following line won't block after 20 processes
        # have been created and running, instead it will carry 
        # on until all 1000 processes are created.
        p.start()

    # inside main process, wait for all processes to finish
    for p in all_processes:
        p.join()

The above code will create total_task_num processes but only concurrency processes will be running while other processes are blocked, consuming precious system resources.

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;

At least in Android Studio 2.2.3 with default key mapping, to comment or uncomment a select text, same hotkeys are used as Toggle. Using the hotkeys changes the state from comment to uncomment, and next time Uncomment to comment on next and vice versa.

1. Comment / uncomment a block of code

Comment sample: /* --- Code block ---- */

Hotkey: Ctrl + Shift + "/"

Using the same key combinations again will "toggle" commenting or uncommenting the selection.

2. Comment / uncomment a line of code

Comment sample: // -- Code ---

Hotkey: Ctrl + "/"

Using the same key combinations again will "toggle" commenting or uncommenting the selection.

Note: Key mapping can be changed to different schemes like eclipse, visual studio... or to the custom hotkeys in File -> Settings -> Keymap

Another problem, in the presence of a NAMESPACE, is that you are trying to run an unexported function from package foo.

For example (contrived, I know, but):

> mod <- prcomp(USArrests, scale = TRUE)
> plot.prcomp(mod)
Error: could not find function "plot.prcomp"

Firstly, you shouldn't be calling S3 methods directly, but lets assume plot.prcomp was actually some useful internal function in package foo. To call such function if you know what you are doing requires the use of :::. You also need to know the namespace in which the function is found. Using getAnywhere() we find that the function is in package stats:

> getAnywhere(plot.prcomp)
A single object matching ‘plot.prcomp’ was found
It was found in the following places
  registered S3 method for plot from namespace stats
  namespace:stats
with value

function (x, main = deparse(substitute(x)), ...) 
screeplot.default(x, main = main, ...)
<environment: namespace:stats>

So we can now call it directly using:

> stats:::plot.prcomp(mod)

I've used plot.prcomp just as an example to illustrate the purpose. In normal use you shouldn't be calling S3 methods like this. But as I said, if the function you want to call exists (it might be a hidden utility function for example), but is in a namespace, R will report that it can't find the function unless you tell it which namespace to look in.

Compare this to the following: stats::plot.prcomp The above fails because while stats uses plot.prcomp, it is not exported from stats as the error rightly tells us:

Error: 'plot.prcomp' is not an exported object from 'namespace:stats'

This is documented as follows:

pkg::name returns the value of the exported variable name in namespace pkg, whereas pkg:::name returns the value of the internal variable name.

Another very basic free profiler: http://expressprofiler.codeplex.com

May be with:

SELECT count(*) FROM `table` 
where 
    created_at>='2011-03-17 06:42:10' and created_at<='2011-03-17 07:42:50';

or use between:

SELECT count(*) FROM `table` 
where 
    created_at between '2011-03-17 06:42:10' and '2011-03-17 07:42:50';

You can change the datetime as per your need. May be use curdate() or now() to get the desired dates.

There are no default constructors in Go, but you can declare methods for any type. You could make it a habit to declare a method called "Init". Not sure if how this relates to best practices, but it helps keep names short without loosing clarity.

package main

import "fmt"

type Thing struct {
    Name string
    Num int
}

func (t *Thing) Init(name string, num int) {
    t.Name = name
    t.Num = num
}

func main() {
    t := new(Thing)
    t.Init("Hello", 5)
    fmt.Printf("%s: %d\n", t.Name, t.Num)
}

The result is:

Hello: 5

IE will cache URLs in order to make loading faster, but if you're, say, polling a server at intervals trying to get new information, IE will cache that URL and will likely return the same data set you've always had.

Regardless of how you end up doing your GET request - vanilla JavaScript, Prototype, jQuery, etc - make sure that you put a mechanism in place to combat caching. In order to combat that, append a unique token to the end of the URL you're going to be hitting. This can be done by:

var sURL = '/your/url.html?' + (new Date()).getTime();

This will append a unique timestamp to the end of the URL and will prevent any caching from happening.

You say loop .. so if you want to do this for a dir instead of the current document;

Dim sFile As Variant
Dim oShell: Set oShell = CreateObject("Shell.Application")
Dim oDir:   Set oDir = oShell.Namespace("c:\foo")

For Each sFile In oDir.Items
   Debug.Print oDir.GetDetailsOf(sFile, XXX) 
Next

Where XXX is an attribute column index, 9 for Author for example. To list available indexes for your reference you can replace the for loop with;

for i = 0 To 40
   debug.? i, oDir.GetDetailsOf(oDir.Items, i)
Next

Quickly for a single file/attribute:

Const PROP_COMPUTER As Long = 56

With CreateObject("Shell.Application").Namespace("C:\HOSTDIRECTORY")
    MsgBox .GetDetailsOf(.Items.Item("FILE.NAME"), PROP_COMPUTER)
End With

It's little too late but this really works for me.

1. react-native run-android.
2. react-native start.

First command will build apk for android and deploy it on your device if its connected. When you open the App it will show red screen with error. Then run second command which will run packager and build app bundle for you.

I think this does a good job of explaining.

The following is a UNION query that uses an ORDER BY clause:

select supplier_id, supplier_name
from suppliers
where supplier_id > 2000
UNION
select company_id, company_name
from companies
where company_id > 1000
ORDER BY 2;

Since the column names are different between the two "select" statements, it is more advantageous to reference the columns in the ORDER BY clause by their position in the result set.

In this example, we've sorted the results by supplier_name / company_name in ascending order, as denoted by the "ORDER BY 2".

The supplier_name / company_name fields are in position #2 in the result set.

Taken from here: http://www.techonthenet.com/sql/union.php

Example:

<input type="button" value="Click me" id="myButton">
<script>
    var myButton = document.getElementById("myButton");
    var test = "zipzambam";
    myButton.onclick = function(eventObject) {
        if (!eventObject) {
            eventObject = window.event;
        }
        if (!eventObject.target) {
            eventObject.target = eventObject.srcElement;
        }
        alert(eventObject.target);
        alert(test);
    };
    (function(myMessage) {
        alert(myMessage);
    })("Hello");
</script>

Open a TCP socket on port 80, start listening for new connections, implement this. Depending on your purposes, you can ignore almost everything. At the easiest, you can send the same response for every request, which just involves writing text to the socket.

Let's say we want to apply a function add5 to columns 'a' and 'b' of DataFrame df

def add5(x):
    return x+5

df[['a', 'b']].apply(add5)

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

Is there any particular reason that you need to use find? You can just use ls to find files that match a pattern in a directory.

ls /dev/abc-*

If you do need to use find, you can use the -maxdepth 1 switch to only apply to the specified directory.

Add a min attribute

<input type="number" min="0">

My 2cents is that they should be avoided in two cases:

1) When you have a variable that is used in many rows and you increase/decrease it on the first statement that uses it (or last, or, even worse, in the middle):

// It's Java, but applies to Js too
vi = list.get ( ++i );
vi1 = list.get ( i + 1 )
out.println ( "Processing values: " + vi + ", " + vi1 )
if ( i < list.size () - 1 ) ...

In examples like this, you can easily miss that the variable is auto-incremented/decremented or even remove the first statement. In other words, use it only in very short blocks or where the variable appears in the block on just a couple of close statements.

2) In case of multiple ++ and -- about the same variable in the same statement. It's very hard to remember what happens in cases like this:

result = ( ++x - --x ) * x++;

Exams and professional tests asks about examples like above and indeed I've stumbled upon this question while looking for documentation about one of them, but in real life one shouldn't be forced to think so much about a single line of code.

Try typeof -- Look for 'undefined' to say it doesn't exist, 'function' for a function. JSFiddle for this code

function thisishere() {
    return false;
}
alert("thisishere() is a " + typeof thisishere);
alert("thisisnthere() is " + typeof thisisnthere);

Or as an if:

if (typeof thisishere === 'function') {
    // function exists
}

Or with a return value, on a single line:

var exists = (typeof thisishere === 'function') ? "Value if true" : "Value if false";
var exists = (typeof thisishere === 'function') // Returns true or false

The date function can return this if you specify the format correctly:

$daynum = date("w", strtotime("wednesday"));

will return 0 for Sunday through to 6 for Saturday.

An alternative format is:

$daynum = date("N", strtotime("wednesday"));

which will return 1 for Monday through to 7 for Sunday (this is the ISO-8601 represensation).

Try this,

$(document).ready(function(){
$(".items").delegate("tr.classname", "click", function(data){
            alert(data.target.innerHTML);//this will show the inner html
    alert($(this).find('td:eq(0)').html());//this will alert the value in the 1st column.
    });
});

Yes, it absolutely is - assuming you've got the appropriate security permissions. Use Field.setAccessible(true) first if you're accessing it from a different class.

import java.lang.reflect.*;

class Other
{
    private String str;
    public void setStr(String value)
    {
        str = value;
    }
}

class Test
{
    public static void main(String[] args)
        // Just for the ease of a throwaway test. Don't
        // do this normally!
        throws Exception
    {
        Other t = new Other();
        t.setStr("hi");
        Field field = Other.class.getDeclaredField("str");
        field.setAccessible(true);
        Object value = field.get(t);
        System.out.println(value);
    }
}

And no, you shouldn't normally do this... it's subverting the intentions of the original author of the class. For example, there may well be validation applied in any situation where the field can normally be set, or other fields may be changed at the same time. You're effectively violating the intended level of encapsulation.

Refer to example at this link. It may be help to you.

I'm a complete noob on Entity but this is how I would do it in theory...

var name = yourDbContext.MyTable.Find(1).Name;

If It's A Primary Key.

-- OR --

var name = yourDbContext.MyTable.SingleOrDefault(mytable => mytable.UserId == 1).Name;

-- OR --

For whole Column:

var names = yourDbContext.MyTable
.Where(mytable => mytable.UserId == 1)
.Select(column => column.Name); //You can '.ToList();' this....

Content is what is passed as children. View is the template of the current component.

The view is initialized before the content and ngAfterViewInit() is therefore called before ngAfterContentInit().

** ngAfterViewInit() is called when the bindings of the children directives (or components) have been checked for the first time. Hence its perfect for accessing and manipulating DOM with Angular 2 components. As @Günter Zöchbauer mentioned before is correct @ViewChild() hence runs fine inside it.

Example:

@Component({
    selector: 'widget-three',
    template: `<input #input1 type="text">`
})
export class WidgetThree{
    @ViewChild('input1') input1;

    constructor(private renderer:Renderer){}

    ngAfterViewInit(){
        this.renderer.invokeElementMethod(
            this.input1.nativeElement,
            'focus',
            []
        )
    }
}

The appropriate way for doing this:

@app.route('/')
def index():
    if form.validate_on_submit():
        if 'download' in request.form:
            pass # do something
        elif 'watch' in request.form:
            pass # do something else

Put watch and download buttons into your template:

<input type="submit" name="download" value="Download">
<input type="submit" name="watch" value="Watch">

C++98 and C++03

This answer is for the older versions of the C++ standard. The C++11 and C++14 versions of the standard do not formally contain 'sequence points'; operations are 'sequenced before' or 'unsequenced' or 'indeterminately sequenced' instead. The net effect is essentially the same, but the terminology is different.

Disclaimer : Okay. This answer is a bit long. So have patience while reading it. If you already know these things, reading them again won't make you crazy.

Pre-requisites : An elementary knowledge of C++ Standard

What are Sequence Points?

The Standard says

At certain specified points in the execution sequence called sequence points, all side effects of previous evaluations shall be complete and no side effects of subsequent evaluations shall have taken place. (§1.9/7)

Side effects? What are side effects?

Evaluation of an expression produces something and if in addition there is a change in the state of the execution environment it is said that the expression (its evaluation) has some side effect(s).

For example:

int x = y++; //where y is also an int

In addition to the initialization operation the value of y gets changed due to the side effect of ++ operator.

So far so good. Moving on to sequence points. An alternation definition of seq-points given by the comp.lang.c author Steve Summit:

Sequence point is a point in time at which the dust has settled and all side effects which have been seen so far are guaranteed to be complete.

What are the common sequence points listed in the C++ Standard ?

Those are:

• at the end of the evaluation of full expression (§1.9/16) (A full-expression is an expression that is not a subexpression of another expression.)¹

  Example :

  int a = 5; // ; is a sequence point here
  

• in the evaluation of each of the following expressions after the evaluation of the first expression (§1.9/18) ²

  • a && b (§5.14)
  • a || b (§5.15)
  • a ? b : c (§5.16)
  • a , b (§5.18) (here a , b is a comma operator; in func(a,a++) , is not a comma operator, it's merely a separator between the arguments a and a++. Thus the behaviour is undefined in that case (if a is considered to be a primitive type))
    

• at a function call (whether or not the function is inline), after the evaluation of all function arguments (if any) which takes place before execution of any expressions or statements in the function body (§1.9/17).

_{1 : Note : the evaluation of a full-expression can include the evaluation of subexpressions that are not lexically part of the full-expression. For example, subexpressions involved in evaluating default argument expressions (8.3.6) are considered to be created in the expression that calls the function, not the expression that defines the default argument}

_{2 : The operators indicated are the built-in operators, as described in clause 5. When one of these operators is overloaded (clause 13) in a valid context, thus designating a user-defined operator function, the expression designates a function invocation and the operands form an argument list, without an implied sequence point between them.}

What is Undefined Behaviour?

The Standard defines Undefined Behaviour in Section §1.3.12 as

behavior, such as might arise upon use of an erroneous program construct or erroneous data, for which this International Standard imposes no requirements ³.

Undefined behavior may also be expected when this International Standard omits the description of any explicit definition of behavior.

_{3 : permissible undefined behavior ranges from ignoring the situation completely with unpredictable results, to behaving during translation or program execution in a documented manner characteristic of the environment (with or with- out the issuance of a diagnostic message), to terminating a translation or execution (with the issuance of a diagnostic message).}

In short, undefined behaviour means anything can happen from daemons flying out of your nose to your girlfriend getting pregnant.

What is the relation between Undefined Behaviour and Sequence Points?

Before I get into that you must know the difference(s) between Undefined Behaviour, Unspecified Behaviour and Implementation Defined Behaviour.

You must also know that the order of evaluation of operands of individual operators and subexpressions of individual expressions, and the order in which side effects take place, is unspecified.

For example:

int x = 5, y = 6;

int z = x++ + y++; //it is unspecified whether x++ or y++ will be evaluated first.

Another example here.

Now the Standard in §5/4 says

• 1) Between the previous and next sequence point a scalar object shall have its stored value modified at most once by the evaluation of an expression.

What does it mean?

Informally it means that between two sequence points a variable must not be modified more than once. In an expression statement, the next sequence point is usually at the terminating semicolon, and the previous sequence point is at the end of the previous statement. An expression may also contain intermediate sequence points.

From the above sentence the following expressions invoke Undefined Behaviour:

i++ * ++i;   // UB, i is modified more than once btw two SPs
i = ++i;     // UB, same as above
++i = 2;     // UB, same as above
i = ++i + 1; // UB, same as above
++++++i;     // UB, parsed as (++(++(++i)))

i = (i, ++i, ++i); // UB, there's no SP between `++i` (right most) and assignment to `i` (`i` is modified more than once btw two SPs)

But the following expressions are fine:

i = (i, ++i, 1) + 1; // well defined (AFAIK)
i = (++i, i++, i);   // well defined 
int j = i;
j = (++i, i++, j*i); // well defined

• 2) Furthermore, the prior value shall be accessed only to determine the value to be stored.

What does it mean? It means if an object is written to within a full expression, any and all accesses to it within the same expression must be directly involved in the computation of the value to be written.

For example in i = i + 1 all the access of i (in L.H.S and in R.H.S) are directly involved in computation of the value to be written. So it is fine.

This rule effectively constrains legal expressions to those in which the accesses demonstrably precede the modification.

Example 1:

std::printf("%d %d", i,++i); // invokes Undefined Behaviour because of Rule no 2

Example 2:

a[i] = i++ // or a[++i] = i or a[i++] = ++i etc

is disallowed because one of the accesses of i (the one in a[i]) has nothing to do with the value which ends up being stored in i (which happens over in i++), and so there's no good way to define--either for our understanding or the compiler's--whether the access should take place before or after the incremented value is stored. So the behaviour is undefined.

Example 3 :

int x = i + i++ ;// Similar to above

You need to change your frame of mind. You are writing PHP, not whatever else it is that you are used to write. Debugging in PHP is not done in a console environment.

In PHP, you have 3 categories of debugging solutions:

1. Output to a webpage (see dBug library for a nicer view of things).
2. Write to a log file
3. In session debugging with xDebug

Learn to use those instead of trying to make PHP behave like whatever other language you are used to.

If we want output like 'string0123456789' then we can use map function and join method of string.

>>> 'string'+"".join(map(str,xrange(10)))
'string0123456789'

If we want List of string values then use list comprehension method.

>>> ['string'+i for i in map(str,xrange(10))]
['string0', 'string1', 'string2', 'string3', 'string4', 'string5', 'string6', 'string7', 'string8', 'string9']

Note:

Use xrange() for Python 2.x

USe range() for Python 3.x

In eclipse go to

Window-> Java -> Installed JREs

You can remove your current installed jre and add the jdk by specifying the path to where the jdk is installed.

In my case,

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

use rtrim()

rtrim($string,',');

In my case, I was calling this.setState({}) correctly, but I my function wasn't bound to this, so it wasn't working. Adding .bind(this) to the function call or doing this.foo = this.foo.bind(this) in the constructor fixed it.

You can use .length with just a descendant selector, like this:

var count = $("#selected li").length;

If you have to use .children(), then it's like this:

var count = $("#selected ul").children().length;

You can test both versions here.

Hey how about to copy all fields, change one of them to the same value + something else.

INSERT INTO Table (foo, bar, Event_ID)
SELECT foo, bar, Event_ID+"155"
  FROM Table
 WHERE Event_ID = "120"

Something none of the other answers touch on is that your first loop is indexing though the list. Whereas the for-each loop is using an Iterator. Some lists like LinkedList will iterate faster with an Iterator versus get(i). This is because because link list's iterator keeps track of the current pointer. Whereas each get in your for i=0 to 9 has to recompute the offset into the linked list. In general, its better to use for-each or an Iterator because it will be using Collections iterator, which in theory is optimized for the collection type.

Let's say you have:

<a></a>

<(.*)> would match a></a where as <(.*?)> would match a. The latter stops after the first match of >. It checks for one or 0 matches of .* followed by the next expression.

The first expression <(.*)> doesn't stop when matching the first >. It will continue until the last match of >.

This is what I put as a menu option where I made a button on a JFrame to display another JFrame. I wanted only the new frame to be visible, and not to destroy the one behind it. I initially hid the first JFrame, while the new one became visible. Upon closing of the new JFrame, I disposed of it followed by an action of making the old one visible again.

Note: The following code expands off of Ravinda's answer and ng is a JButton:

ng.addActionListener((ActionEvent e) -> {
    setVisible(false);
    JFrame j = new JFrame("NAME");
    j.setVisible(true);
    j.addWindowListener(new java.awt.event.WindowAdapter() {
        @Override
        public void windowClosing(java.awt.event.WindowEvent windowEvent) {
            setVisible(true);
        }
    });
});

Just to add to how to use map files. I use chrome for ubuntu and if I go to sources and click on a file, if there is a map file a message comes up telling me that I can view the original file and how to do it.

For the Angular files that I worked with today I click

Ctrl-P and a list of original files comes up in a small window.

I can then browse through the list to view the file that I would like to inspect and check where the issue might be.

Implementation of the upload progress bar is easy and doesn't require any additional PHP extension, JavaScript or Flash. But you need PHP 5.4 and newer.

You have to enable collecting of the upload progress information by setting the directive session.upload_progress.enabled to On in php.ini.

Then add a hidden input to the HTML upload form just before any other file inputs. HTML attribute name of that hidden input should be the same as the value of the directive session.upload_progress.name from php.ini (eventually preceded by session.upload_progress.prefix). The value attribute is up to you, it will be used as part of the session key.

HTML form could looks like this:

<form action="upload.php" method="POST" enctype="multipart/form-data">
   <input type="hidden" name="<?php echo ini_get('session.upload_progress.prefix').ini_get('session.upload_progress.name'); ?>" value="myupload" />
   <input type="file" name="file1" />
   <input type="submit" />
</form>

When you send this form, PHP should create a new key in the $_SESSION superglobal structure which will be populated with the upload status information. The key is concatenated name and value of the hidden input.

In PHP you can take a look at populated upload information:

var_dump($_SESSION[
    ini_get('session.upload_progress.prefix')
   .ini_get('session.upload_progress.name')
   .'_myupload'
]);

The output will look similarly to the following:

$_SESSION["upload_progress_myupload"] = array(
  "start_time" => 1234567890,   // The request time
  "content_length" => 57343257, // POST content length
  "bytes_processed" => 54321,   // Amount of bytes received and processed
  "done" => false,              // true when the POST handler has finished, successfully or not
  "files" => array(
    0 => array(
      "field_name" => "file1",    // Name of the <input /> field
      // The following 3 elements equals those in $_FILES
      "name" => "filename.ext",
      "tmp_name" => "/tmp/phpxxxxxx",
      "error" => 0,
      "done" => false,            // True when the POST handler has finished handling this file
      "start_time" => 1234567890, // When this file has started to be processed
      "bytes_processed" => 54321, // Number of bytes received and processed for this file
    )
  )
);

There is all the information needed to create a progress bar — you have the information if the upload is still in progress, the information how many bytes is going to be transferred in total and how many bytes has been transferred already.

To present the upload progress to the user, write an another PHP script than the uploading one, which will only look at the upload information in the session and return it in the JSON format, for example. This script can be called periodically, for example every second, using AJAX and information presented to the user.

You are even able to cancel the upload by setting the $_SESSION[$key]['cancel_upload'] to true.

For detailed information, additional settings and user's comments see PHP manual.

<configuration>
    <system.web>
        <httpRuntime maxRequestLength="1048576" />
    </system.web>
</configuration>

From here.

For IIS7 and above, you also need to add the lines below:

 <system.webServer>
   <security>
      <requestFiltering>
         <requestLimits maxAllowedContentLength="1073741824" />
      </requestFiltering>
   </security>
 </system.webServer>

If you have web.xml then

HTML/JSP

<form action="${pageContext.request.contextPath}/myservlet" method="post">
    <input type="submit" name="button1" value="Button 1" />
</form>

web.xml

<servlet>
        <display-name>Servlet Name</display-name>
        <servlet-name>myservlet</servlet-name>
        <servlet-class>package.SomeController</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>myservlet</servlet-name>
    <url-pattern>/myservlet</url-pattern>
</servlet-mapping>

Java SomeController.java

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        System.out.println("Write your code below");
}

Enum.valueOf() only checks the constant name, so you need to pass it "COLUMN_HEADINGS" instead of "columnHeadings". Your name property has nothing to do with Enum internals.

To address the questions/concerns in the comments:

The enum's "builtin" (implicitly declared) valueOf(String name) method will look up an enum constant with that exact name. If your input is "columnHeadings", you have (at least) three choices:

1. Forget about the naming conventions for a bit and just name your constants as it makes most sense: enum PropName { contents, columnHeadings, ...}. This is obviously the most convenient.
2. Convert your camelCase input into UPPER_SNAKE_CASE before calling valueOf, if you're really fond of naming conventions.
3. Implement your own lookup method instead of the builtin valueOf to find the corresponding constant for an input. This makes most sense if there are multiple possible mappings for the same set of constants.

For me what worked is having it like this

style={{ backgroundImage: `url(${require("./resources/img/banners/3.jpg")})` }}

Instead of the code you wrote, you may use ArrayList.addAll() to merge the lists, Collections.sort() to sort it and finally traverse of the resulting ArrayList to remove duplicates. The aggregate complexity is thus O(n)+O(n*log(n))+O(n) which is equivalent to O(n*log(n)).

you could build a function that takes a list as a parameter and returns a shuffled version of the list:

from random import *

def listshuffler(inputlist):
    for i in range(len(inputlist)):
        swap = randint(0,len(inputlist)-1)
        temp = inputlist[swap]
        inputlist[swap] = inputlist[i]
        inputlist[i] = temp
    return inputlist

Category to the rescue!

Add this to a shared utility header somewhere:

@interface UIScrollView (ScrollToBottom)
- (void)scrollToBottomAnimated:(BOOL)animated;
@end

And then to that utility implementation:

@implementation UIScrollView(ScrollToBottom)
- (void)scrollToBottomAnimated:(BOOL)animated
{
     CGPoint bottomOffset = CGPointMake(0, self.contentSize.height - self.bounds.size.height);
     [self setContentOffset:bottomOffset animated:animated];
}
@end

Then Implement it wherever you like, for instance:

[[myWebView scrollView] scrollToBottomAnimated:YES];

Adding this because nobody did yet, and this seems to be asked for and implemented a lot with hashes, but it's always done very poorly...

This takes a string input, and a maximum number you want the hash to equal, and produces a unique number based on the string input.

You can use this to produce a unique index into an array of images (If you want to return a specific avatar for a user, chosen at random, but also chosen based on their name, so it will always be assigned to someone with that name).

You can also use this, of course, to return an index into an array of colors, like for generating unique avatar background colors based on someone's name.

function hashInt (str, max = 1000) {
    var hash = 0;
    for (var i = 0; i < str.length; i++) {
      hash = ((hash << 5) - hash) + str.charCodeAt(i);
      hash = hash & hash;
    }
    return Math.round(max * Math.abs(hash) / 2147483648);
}

The easiest option is to start a windows forms project, then change the output-type to Console Application. Alternatively, just add a reference to System.Windows.Forms.dll, and start coding:

using System.Windows.Forms;

[STAThread]
static void Main() {
    Application.EnableVisualStyles();
    Application.Run(new Form()); // or whatever
}

The important bit is the [STAThread] on your Main() method, required for full COM support.

You can use regular expression.

var txt="some text 2";
var numb = txt.match(/\d/g);
alert (numb);

That will alert 2.

Here is what I use for this situation as a module (in my formhelper.js):

define(function(){
    FormHelper = {};

    FormHelper.parseForm = function($form){
        var serialized = $form.serializeArray();
        var s = '';
        var data = {};
        for(s in serialized){
            data[serialized[s]['name']] = serialized[s]['value']
        }
        return JSON.stringify(data);
    }

    return FormHelper;
});

It kind of sucks that I can't seem to find another way to do what I want to do.

This does return this JSON for me:

{"first_name":"John","last_name":"Smith","age":"30"}

A possible solution:

import pandas as pd
import numpy as np

df=pd.DataFrame(['ONE','Two', np.nan],columns=['x']) 
xLower = df["x"].map(lambda x: x if type(x)!=str else x.lower())
print (xLower)

And a result:

0    one
1    two
2    NaN
Name: x, dtype: object

Not sure about the efficiency though.

How to Edit Multiple Commit Dates

Other answers aren't very convenient for editing several commit dates. I've come back to this question after a few years to share a technique.

To change the dates of the last 4 commits:

git rebase -i HEAD~4

Edit the rebase as follows, inserting exec lines to modify dates as needed:

pick 4ca564e Do something
exec git commit --amend --no-edit --date "1 Oct 2019 12:00:00 PDT"
pick 1670583 Add another thing
exec git commit --amend --no-edit --date "2 Oct 2019 12:00:00 PDT"
pick b54021c Add some tests
exec git commit --amend --no-edit --date "3 Oct 2019 12:00:00 PDT"
pick e8f6653 Fix the broken thing
exec git commit --amend --no-edit --date "4 Oct 2019 12:00:00 PDT"

i'd try tinyproxy. in fact, the vey best would be to embedd a scripting language there... sounds like a perfect job for Lua, especially after seeing how well it worked for mysqlproxy

As you said, in MySQL USAGE is synonymous with "no privileges". From the MySQL Reference Manual:

The USAGE privilege specifier stands for "no privileges." It is used at the global level with GRANT to modify account attributes such as resource limits or SSL characteristics without affecting existing account privileges.

USAGE is a way to tell MySQL that an account exists without conferring any real privileges to that account. They merely have permission to use the MySQL server, hence USAGE. It corresponds to a row in the `mysql`.`user` table with no privileges set.

The IDENTIFIED BY clause indicates that a password is set for that user. How do we know a user is who they say they are? They identify themselves by sending the correct password for their account.

A user's password is one of those global level account attributes that isn't tied to a specific database or table. It also lives in the `mysql`.`user` table. If the user does not have any other privileges ON *.*, they are granted USAGE ON *.* and their password hash is displayed there. This is often a side effect of a CREATE USER statement. When a user is created in that way, they initially have no privileges so they are merely granted USAGE.

One thing to note:
I have had issues with websockets and corporate firewalls. (Using HTTPS helps but not always.)

See https://github.com/LearnBoost/socket.io/wiki/Socket.IO-and-firewall-software https://github.com/sockjs/sockjs-client/issues/94

I assume there aren't as many issues with Server-Sent Events. But I don't know.

That said, WebSockets are tons of fun. I have a little web game that uses websockets (via Socket.IO) (http://minibman.com)

PHP has a function called get_browser() that will return an object (or array if you so choose) with details about the users' browser and what it can do.

A simple look through gave me this code:

$browser = get_browser( null, true );
if( $browser['name'] == "Firefox" )
    if( $browser['majorversion'] == 4 )
        echo "You're using Firefox version 4!";

This is not a surefire way (as it reads from HTTP_USER_AGENT, which can be spoofed, and will sometimes be analyzed wrong by php), but it's the easiest one that you can find as far as I know.

In the "disable" script, the order by clause should be that:

ORDER BY c.constraint_type DESC, c.last_change DESC

The goal of this clause is disable the constraints in the right order.

try

async function load_home(){
  content.innerHTML = await (await fetch('home.html')).text();
}

async function load_home() {_x000D_
  let url = 'https://kamil-kielczewski.github.io/fractals/mandelbulb.html'_x000D_
_x000D_
  content.innerHTML = await (await fetch(url)).text();_x000D_
}

<div id="topBar"> <a href="#" onclick="load_home()"> HOME </a> </div>_x000D_
<div id="content"> </div>

If you want a certain message, use this:

String phoneNo = "";//The phone number you want to text
String sms= "";//The message you want to text to the phone

Intent smsIntent = new Intent(Intent.ACTION_VIEW, Uri.fromParts("sms", phoneNo, null));
smsIntent.putExtra("sms_body",sms);
startActivity(smsIntent);

All you need to do is add the mat-icon-button directive to the button element in your template. Within the button element specify your desired icon with a mat-icon component.

You'll need to import MatButtonModule and MatIconModule in your app module file.

From the Angular Material buttons example page, hit the view code button and you'll see several examples which use the material icons font, eg.

<button mat-icon-button>
  <mat-icon aria-label="Example icon-button with a heart icon">favorite</mat-icon>
</button>

In your case, use

<mat-icon>thumb_up</mat-icon>

As per the getting started guide at https://material.angular.io/guide/getting-started, you'll need to load the material icon font in your index.html.

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

Or import it in your global styles.scss.

@import url("https://fonts.googleapis.com/icon?family=Material+Icons");

As it mentions, any icon font can be used with the mat-icon component.

To convert a valid JSON string back, you can use the json_decode() method.

To convert it back to an object use this method:

$jObj = json_decode($jsonString);

And to convert it to a associative array, set the second parameter to true:

$jArr = json_decode($jsonString, true);

By the way to convert your mentioned string back to either of those, you should have a valid JSON string. To achieve it, you should do the following:

1. In the Coords array, remove the two " (double quote marks) from the start and end of the object.
2. The objects in an array are comma seprated (,), so add commas between the objects in the Coords array..

And you will have a valid JSON String..

Here is your JSON String I converted to a valid one: http://pastebin.com/R16NVerw

I'm very late in the game, but this might help others. I hit this same problem with $.get and I didn't want to blindly turn off caching and I didn't like the timestamp patch. So after a little research I found that you can simply use $.post instead of $.get which does NOT use caching. Simple as that. :)

My solution requires no additional css and works with any combination of input-addon, input-btn and form-control. It just uses pre-existing bootstrap classes

The best way is you save this information, for example, in a structure:

typedef struct {
     int *array;
     int elements;
} list_s;

Implement all necessary functions such as create, destroy, check equality, and everything else you need. It is easier to pass as a parameter.

Just came up with this solution that seems to solve all my ajax problems.

For on ready events I now use this:

function loaded(selector, callback){
    //trigger after page load.
    $(function () {
        callback($(selector));
    });
    //trigger after page update eg ajax event or jquery insert.
    $(document).on('DOMNodeInserted', selector, function () {
        callback($(this));
    });
}

loaded('.foo', function(el){
    //some action
    el.css('background', 'black');
});

And for normal trigger events I now use this:

$(document).on('click', '.foo', function () {
    //some action
    $(this).css('background', 'pink');
});

JonH has covered very well the part on how to write the query. There is another significant issue that must be mentioned too, however, which is the performance characteristics of such a query. Let's repeat it here (adapted to Oracle):

SELECT EmployeeName FROM EmployeeTable WHERE LENGTH(EmployeeName) > 4;

This query is restricting the result of a function applied to a column value (the result of applying the LENGTH function to the EmployeeName column). In Oracle, and probably in all other RDBMSs, this means that a regular index on EmployeeName will be useless to answer this query; the database will do a full table scan, which can be really costly.

However, various databases offer a function indexes feature that is designed to speed up queries like this. For example, in Oracle, you can create an index like this:

CREATE INDEX EmployeeTable_EmployeeName_Length ON EmployeeTable(LENGTH(EmployeeName));

This might still not help in your case, however, because the index might not be very selective for your condition. By this I mean the following: you're asking for rows where the name's length is more than 4. Let's assume that 80% of the employee names in that table are longer than 4. Well, then the database is likely going to conclude (correctly) that it's not worth using the index, because it's probably going to have to read most of the blocks in the table anyway.

However, if you changed the query to say LENGTH(EmployeeName) <= 4, or LENGTH(EmployeeName) > 35, assuming that very few employees have names with fewer than 5 character or more than 35, then the index would get picked and improve performance.

Anyway, in short: beware of the performance characteristics of queries like the one you're trying to write.

I found an a bit different solution of my problem regarding this context. Thought worth sharing.

Most of the example create readStreams from file. But in my case readStream has to be created from JSON string coming from a message pool.

var jsonStream = through2.obj(function(chunk, encoding, callback) {
                    this.push(JSON.stringify(chunk, null, 4) + '\n');
                    callback();
                });
// message.value --> value/text to write in write.txt 
jsonStream.write(JSON.parse(message.value));
var writeStream = sftp.createWriteStream("/path/to/write/write.txt");

//"close" event didn't work for me!
writeStream.on( 'close', function () {
    console.log( "- done!" );
    sftp.end();
    }
);

//"finish" event didn't work for me either!
writeStream.on( 'close', function () {
    console.log( "- done!"
        sftp.end();
        }
);

// finally this worked for me!
jsonStream.on('data', function(data) {
    var toString = Object.prototype.toString.call(data);
    console.log('type of data:', toString);
    console.log( "- file transferred" );
});

jsonStream.pipe( writeStream );

No Yes, using the File API in newer browsers. See TJ's answer for details.

If you need to support older browsers as well, you will have to use a Flash-based uploader like SWFUpload or Uploadify to do this.

The SWFUpload Features Demo shows how the file_size_limit setting works.

Note that this (obviously) needs Flash, plus the way it works is a bit different from normal upload forms.

Strings are slower in joins and in real life they are very rarely really unique (even when they are supposed to be). The only advantage is that they can reduce the number of joins if you are joining to the primary table only to get the name. However, strings are also often subject to change thus creating the problem of having to fix all related records when the company name changes or the person gets married. This can be a huge performance hit and if all tables that should be related somehow are not related (this happens more often than you think), then you might have data mismatches as well. An integer that will never change through the life of the record is a far safer choice from a data integrity standpoint as well as from a performance standpoint. Natural keys are usually not so good for maintenance of the data.

I also want to point out that the best of both worlds is often to use an autoincrementing key (or in some specialized cases, a GUID) as the PK and then put a unique index on the natural key. You get the faster joins, you don;t get duplicate records, and you don't have to update a million child records because a company name changed.

The most efficient one is Ctrl + ..

It helps to automate insertions of using directives. It works if the focus is on a new identifier, e.g. class name.

Prefix the call with Module2 (ex. Module2.IDLE). I'm assuming since you asked this that you have IDLE defined multiple times in the project, otherwise this shouldn't be necessary.

The .title() method of a string (either ASCII or Unicode is fine) does this:

>>> "hello world".title()
'Hello World'
>>> u"hello world".title()
u'Hello World'

However, look out for strings with embedded apostrophes, as noted in the docs.

The algorithm uses a simple language-independent definition of a word as groups of consecutive letters. The definition works in many contexts but it means that apostrophes in contractions and possessives form word boundaries, which may not be the desired result:

>>> "they're bill's friends from the UK".title()
"They'Re Bill'S Friends From The Uk"

Had this issue after a reinstall today. Make sure the Application Experience service is started and not set to disabled. If its set to manual, I believe VS will start it.

I had to map FAKE/REAL to 0/1 but couldn't find proper answer.

Please find below how to map column name 'type' which has values FAKE/REAL to 0/1
(Note: similar can be applied to any column name and values)

df.loc[df['type'] == 'FAKE', 'type'] = 0
df.loc[df['type'] == 'REAL', 'type'] = 1

Assuming you cannot modify DDL (to create a unique constraint) or are limited to only being able to write DML then check for a null on filtered result of your values against the whole table

        left join 
    funds on funds.ID = T.ID and funds.date = T.date

    funds.ID is null

The ultimate question... Is WebKit supported by IE?

Kind of. Check out Chrome Frame, it's a plugin for Internet Explorer that makes it use the Webkit engine. The only quirk is that you have to persuade your visitors to install the plugin.

Update

Chrome Frame is no longer maintained or supported…

Get all tags from Docker Hub: this command uses the command-line JSON processor jq to select the tag names from the JSON returned by the Docker Hub Registry (the quotes are removed with tr). Replace library with the Docker Hub user name, debian with the image name:

curl -s 'https://registry.hub.docker.com/v2/repositories/library/debian/tags/' | jq -r '."results"[]["name"]'

Please try http://www.osjava.org/jardiff/ - tool is old and the dependency list is large. From the docs, it looks like worth trying.

From Bootstrap's docs about the remote option;

This option is deprecated since v3.3.0 and has been removed in v4. We recommend instead using client-side templating or a data binding framework, or calling jQuery.load yourself.

If a remote URL is provided, content will be loaded one time via jQuery's load method and injected into the .modal-content div. If you're using the data-api, you may alternatively use the href attribute to specify the remote source. An example of this is shown below:

<a data-toggle="modal" href="remote.html" data-target="#modal">Click me</a>

That's the .modal-content div, not .modal-body. If you want to put content inside .modal-body then you need to do that with custom javascript.

So I would call jQuery.load programmatically, meaning you can keep the functionality of the dismiss and/or other buttons as required.

To do this you could use a data tag with the URL from the button that opens the modal, and use the show.bs.modal event to load content into the .modal-body div.

HTML Link/Button

<a href="#" data-toggle="modal" data-load-url="remote.html" data-target="#myModal">Click me</a>

jQuery

$('#myModal').on('show.bs.modal', function (e) {
    var loadurl = $(e.relatedTarget).data('load-url');
    $(this).find('.modal-body').load(loadurl);
});

        let hexString = String(format: "#%02lX%02lX%02lX", lroundf(Float(r * 255)), lroundf(Float(g * 255)),
                               lroundf(Float(b * 255)))

            guard let data = htmlCSSString.data(using: String.Encoding.utf8) else {
                return nil
            }

            return try NSAttributedString(data: data,
                                          options: [.documentType: NSAttributedString.DocumentType.html,

            print("error: ", error)
            return nil

And final you can create UILabel:

func createHtmlLabel(with html: String) -> UILabel {
    let htmlMock = """
    <b>hello</b>, <i>world</i>
    """

    let descriprionLabel = UILabel()
    descriprionLabel.attributedText = htmlMock.htmlAttributed(family: "YourFontFamily", size: 15, color: .red)

    return descriprionLabel
}

Oracle's JVM implementation for Java 8 got rid of the PermGen model and replaced it with Metaspace.

mutable is mainly used on an implementation detail of the class. The user of the class doesn't need to know about it, therefore method's he thinks "should" be const can be. Your example of having a mutex be mutable is a good canonical example.

  $a = array(
      'blue' => 'nice',
      'car' => 'fast',
      'number' => 'none'
  );  
var_dump(array_search('car', array_keys($a)));
var_dump(array_search('blue', array_keys($a)));
var_dump(array_search('number', array_keys($a)));

Here is an example of code, that attempts to featch AJAX data from /Ajax/_AjaxGetItemListHelp/ URL. Upon success, it removes all items from dropdown list with id = OfferTransModel_ItemID and then it fills it with new items based on AJAX call's result:

if (productgrpid != 0) {    
    $.ajax({
        type: "POST",
        url: "/Ajax/_AjaxGetItemListHelp/",
        data:{text:"sam",OfferTransModel_ItemGrpid:productgrpid},
        contentType: "application/json",              
        dataType: "json",
        success: function (data) {
            $("#OfferTransModel_ItemID").empty();

            $.each(data, function () {
                $("#OfferTransModel_ItemID").append($("<option>                                                      
                </option>").val(this['ITEMID']).html(this['ITEMDESC']));
            });
        }
    });
}

Returned AJAX result is expected to return data encoded as AJAX array, where each item contains ITEMID and ITEMDESC elements. For example:

{
    {
        "ITEMID":"13",
        "ITEMDESC":"About"
    },
    {
        "ITEMID":"21",
        "ITEMDESC":"Contact"
    }
}

The OfferTransModel_ItemID listbox is populated with above data and its code should look like:

<select id="OfferTransModel_ItemID" name="OfferTransModel[ItemID]">
    <option value="13">About</option>
    <option value="21">Contact</option>
</select>

When user selects About, form submits 13 as value for this field and 21 when user selects Contact and so on.

Fell free to modify above code if your server returns URL in a different format.

This is not an Xcode bug, though the warning message is not helpful enough to describe the real cause.

This error message occurs when you have several files in your project that have the same name. You just have to delete or rename the files with duplicate names and the problem is solved.

You could also look at the [cxx-rtimers][1] on GitHub, which provide some header-only routines for gathering statistics on the run-time of any code-block where you can create a local variable. Those timers have versions that use std::chrono on C++11, or timers from the Boost library, or standard POSIX timer functions. These timers will report the average, maximum & minimum duration spent within a function, as well as the number of times it is called. They can be used as simply as follows:

#include <rtimers/cxx11.hpp>

void expensiveFunction() {
    static rtimers::cxx11::DefaultTimer timer("expensive");
    auto scopedStartStop = timer.scopedStart();
    // Do something costly...
}

1)

var merged = {};
for(key in obj1)
    merged[key] = obj1[key];
for(key in obj2)
    merged[key] = obj2[key];

2)

var merged = {};
Object.keys(obj1).forEach(k => merged[k] = obj1[k]);
Object.keys(obj2).forEach(k => merged[k] = obj2[k]);

OR

Object.keys(obj1)
    .concat(Object.keys(obj2))
    .forEach(k => merged[k] = k in obj2 ? obj2[k] : obj1[k]);

3) Simplest way:

var merged = {};
Object.assign(merged, obj1, obj2);

This uses the function and waits for it to complete.

http://jsfiddle.net/SN2t6/118/

function getMeta(url){
    var r = $.Deferred();

  $('<img/>').attr('src', url).load(function(){
     var s = {w:this.width, h:this.height};
     r.resolve(s)
  });
  return r;
}

getMeta("http://www.google.hr/images/srpr/logo3w.png").done(function(test){
    alert(test.w + ' ' + test.h);
});

Throwing an exception is the best way of dealing with constructor failure. You should particularly avoid half-constructing an object and then relying on users of your class to detect construction failure by testing flag variables of some sort.

On a related point, the fact that you have several different exception types for dealing with mutex errors worries me slightly. Inheritance is a great tool, but it can be over-used. In this case I would probably prefer a single MutexError exception, possibly containing an informative error message.

Just for completion.

This error might be as well the case if you have a foreign key with VARCHAR(..) and the charset of the referenced table is different from the table referencing it.

e.g. VARCHAR(50) in a Latin1 Table is different than the VARCHAR(50) in a UTF8 Table.

This will print out the query:

$query = "SELECT order_date, no_of_items, shipping_charge, SUM(total_order_amount) as test FROM `orders` WHERE DATE(`order_date`) = DATE(NOW()) GROUP BY DATE(`order_date`)";

$dave= mysql_query($query) or die(mysql_error());
print $query;

This will print out the results:

$query = "SELECT order_date, no_of_items, shipping_charge, SUM(total_order_amount) as test FROM `orders` WHERE DATE(`order_date`) = DATE(NOW()) GROUP BY DATE(`order_date`)";

$dave= mysql_query($query) or die(mysql_error());

while($row = mysql_fetch_assoc($dave)){
    foreach($row as $cname => $cvalue){
        print "$cname: $cvalue\t";
    }
    print "\r\n";
}

There is a getch() function in the ncurses library. You can get it by installing the ncurses-dev package.

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

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

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

This is untested code.

Though the first approach is advocated as 'the angular like' approach, I feel this adds overheads.

Consider if I want to use this myservice.foo function in 10 different controllers. I will have to specify this 'myService' dependency and then $scope.callFoo scope property in all ten of them. This is simply a repetition and somehow violates the DRY principle.

Whereas, if I use the $rootScope approach, I specify this global function gobalFoo only once and it will be available in all my future controllers, no matter how many.

The checked and selected attributes are allowed only two values, which are a copy of the attribute name and (from HTML 5 onwards) an empty string. Giving any other value is an error.

If you don't want to set the attribute, then the entire attribute must be omitted.

Note that in HTML 4 you may omit everything except the value. HTML 5 changed this to omit everything except the name (which makes no practical difference).

Thus, the complete (aside from variations in cAsE) set of valid representations of the attribute are:

<input ... checked="checked"> <!-- All versions of HTML / XHTML -->
<input ...          checked > <!-- Only HTML 4.01 and earlier -->
<input ... checked          > <!-- Only HTML 5 and later -->
<input ... checked=""       > <!-- Only HTML 5 and later -->

Documents served as text/html (HTML or XHTML) will be fed through a tag soup parser, and the presence of a checked attribute (with any value) will be treated as "This element should be checked". Thus, while invalid, checked="true", checked="yes", and checked="false" will all trigger the checked state.

I've not had any inclination to find out what error recovery mechanisms are in place for XML parsing mode should a different value be given to the attribute, but I would expect that the legacy of HTML and/or simple error recovery would treat it in the same way: If the attribute is there then the element is checked.

(And all the above applies equally to selected as it does to checked.)

Simply replace it with nothing:

var string = 'F0123456'; // just an example
string.replace(/^F0+/i, ''); '123456'

For (much) more power and flexibility, use a dedicated spellchecking library like PyEnchant. There's a tutorial, or you could just dive straight in:

>>> import enchant
>>> d = enchant.Dict("en_US")
>>> d.check("Hello")
True
>>> d.check("Helo")
False
>>> d.suggest("Helo")
['He lo', 'He-lo', 'Hello', 'Helot', 'Help', 'Halo', 'Hell', 'Held', 'Helm', 'Hero', "He'll"]
>>>

PyEnchant comes with a few dictionaries (en_GB, en_US, de_DE, fr_FR), but can use any of the OpenOffice ones if you want more languages.

There appears to be a pluralisation library called inflect, but I've no idea whether it's any good.

The -S switch makes sudo read the password from STDIN. This means you can do

echo mypassword | sudo -S command

to pass the password to sudo

However, the suggestions by others that do not involve passing the password as part of a command such as checking if the user is root are probably much better ideas for security reasons

Windows MySQL v5 throws an error but Linux and other versions only raise a warning. This needs to be fixed. WTF?

Also see an attempt to fix this as bug #19498 in the MySQL Bugtracker:

Bryce Nesbitt on April 4 2008 4:36pm:
On MS Windows the "no DEFAULT" rule is an error, while on other platforms it is often a warning. While not a bug, it's possible to get trapped by this if you write code on a lenient platform, and later run it on a strict platform:

Personally, I do view this as a bug. Searching for "BLOB/TEXT column can't have a default value" returns about 2,940 results on Google. Most of them are reports of incompatibilities when trying to install DB scripts that worked on one system but not others.

I am running into the same problem now on a webapp I'm modifying for one of my clients, originally deployed on Linux MySQL v5.0.83-log. I'm running Windows MySQL v5.1.41. Even trying to use the latest version of phpMyAdmin to extract the database, it doesn't report a default for the text column in question. Yet, when I try running an insert on Windows (that works fine on the Linux deployment) I receive an error of no default on ABC column. I try to recreate the table locally with the obvious default (based on a select of unique values for that column) and end up receiving the oh-so-useful BLOB/TEXT column can't have a default value.

Again, not maintaining basic compatability across platforms is unacceptable and is a bug.

How to disable strict mode in MySQL 5 (Windows):

• Edit /my.ini and look for line

  sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
  

• Replace it with

  sql_mode='MYSQL40'
  

• Restart the MySQL service (assuming that it is mysql5)

  net stop mysql5
  net start mysql5
  

If you have root/admin access you might be able to execute

mysql_query("SET @@global.sql_mode='MYSQL40'");

Put the following to your .bashrc

shopt -s extglob

It extends regexes. You can then move all files except one by

mv !(fileOne) ~/path/newFolder

Exceptions in relation to other commands

Note that, in copying directories, the forward-flash cannot be used in the name as noticed in the thread Why extglob except breaking except condition?:

cp -r !(Backups.backupdb) /home/masi/Documents/

so Backups.backupdb/ is wrong here before the negation and I would not use it neither in moving directories because of the risk of using wrongly then globs with other commands and possible other exceptions.

Because the concept of a List is incompatible with the concept of an automatically sorted collection. The point of a List is that after calling list.add(7, elem), a call to list.get(7) will return elem. With an auto-sorted list, the element could end up in an arbitrary position.

I was facing with this problem some time ago and I found java.util.LinkedList is best for my case. It has several methods, with different namings, but they're doing what is needed:

push()    -> LinkedList.addLast(); // Or just LinkedList.add();
pop()     -> LinkedList.pollLast();
shift()   -> LinkedList.pollFirst();
unshift() -> LinkedList.addFirst();

From the Bjarne Stroustrup C++0x FAQ:

__cplusplus

In C++11 the macro __cplusplus will be set to a value that differs from (is greater than) the current 199711L.

Although this isn't as helpful as one would like. gcc (apparently for nearly 10 years) had this value set to 1, ruling out one major compiler, until it was fixed when gcc 4.7.0 came out.

These are the C++ standards and what value you should be able to expect in __cplusplus:

• C++ pre-C++98: __cplusplus is 1.
• C++98: __cplusplus is 199711L.
• C++98 + TR1: This reads as C++98 and there is no way to check that I know of.
• C++11: __cplusplus is 201103L.
• C++14: __cplusplus is 201402L.
• C++17: __cplusplus is 201703L.

If the compiler might be an older gcc, we need to resort to compiler specific hackery (look at a version macro, compare it to a table with implemented features) or use Boost.Config (which provides relevant macros). The advantage of this is that we actually can pick specific features of the new standard, and write a workaround if the feature is missing. This is often preferred over a wholesale solution, as some compilers will claim to implement C++11, but only offer a subset of the features.

The Stdcxx Wiki hosts a comprehensive matrix for compiler support of C++0x features (archive.org link) (if you dare to check for the features yourself).

Unfortunately, more finely-grained checking for features (e.g. individual library functions like std::copy_if) can only be done in the build system of your application (run code with the feature, check if it compiled and produced correct results - autoconf is the tool of choice if taking this route).

To check if a grammar is LL(1), one option is to construct the LL(1) parsing table and check for any conflicts. These conflicts can be

• FIRST/FIRST conflicts, where two different productions would have to be predicted for a nonterminal/terminal pair.
• FIRST/FOLLOW conflicts, where two different productions are predicted, one representing that some production should be taken and expands out to a nonzero number of symbols, and one representing that a production should be used indicating that some nonterminal should be ultimately expanded out to the empty string.
• FOLLOW/FOLLOW conflicts, where two productions indicating that a nonterminal should ultimately be expanded to the empty string conflict with one another.

Let's try this on your grammar by building the FIRST and FOLLOW sets for each of the nonterminals. Here, we get that

FIRST(X) = {a, b, z}
FIRST(Y) = {b, epsilon}
FIRST(Z) = {epsilon} 

We also have that the FOLLOW sets are

FOLLOW(X) = {$}
FOLLOW(Y) = {z}
FOLLOW(Z) = {z}

From this, we can build the following LL(1) parsing table:

    a    b    z   $
X   a    Yz   Yz  
Y        bZ   eps
Z             eps

Since we can build this parsing table with no conflicts, the grammar is LL(1).

To check if a grammar is LR(0) or SLR(1), we begin by building up all of the LR(0) configurating sets for the grammar. In this case, assuming that X is your start symbol, we get the following:

(1)
X' -> .X
X -> .Yz
X -> .a
Y -> .
Y -> .bZ

(2)
X' -> X.

(3)
X -> Y.z

(4)
X -> Yz.

(5)
X -> a.

(6)
Y -> b.Z
Z -> .

(7)
Y -> bZ.

From this, we can see that the grammar is not LR(0) because there are shift/reduce conflicts in states (1) and (6). Specifically, because we have the reduce items Z → . and Y → ., we can't tell whether to reduce the empty string to these symbols or to shift some other symbol. More generally, no grammar with ε-productions is LR(0).

However, this grammar might be SLR(1). To see this, we augment each reduction with the lookahead set for the particular nonterminals. This gives back this set of SLR(1) configurating sets:

(1)
X' -> .X
X -> .Yz [$]
X -> .a  [$]
Y -> .   [z]
Y -> .bZ [z]

(2)
X' -> X.

(3)
X -> Y.z [$]

(4)
X -> Yz. [$]

(5)
X -> a.  [$]

(6)
Y -> b.Z [z]
Z -> .   [z]

(7)
Y -> bZ. [z]

Now, we don't have any more shift-reduce conflicts. The conflict in state (1) has been eliminated because we only reduce when the lookahead is z, which doesn't conflict with any of the other items. Similarly, the conflict in (6) is gone for the same reason.

Hope this helps!

If the program was written in C# you can get the source code in almost its original form using .NET Reflector. You won't be able to see comments and local variable names, but it is very readable.

If it was written C++ it's not so easy... even if you could decompile the code into valid C++ it is unlikely that it will resemble the original source because of inlined functions and optimizations which are hard to reverse.

Please note that by reverse engineering and modifying the source code you might breaking the terms of use of the programs unless you wrote them yourself or have permission from the author.

So far I found gettimeofday a good solution on iOS (iPad), when you want to perform some interval evaluation (say, framerate, timing of a rendering frame...) :

#include <sys/time.h>
struct timeval time;
gettimeofday(&time, NULL);
long millis = (time.tv_sec * 1000) + (time.tv_usec / 1000);

For me this is the correct way, This just worked:

    $linker = rawurldecode("$link");
    <a href="<?php echo $link;?>"   target="_blank"><?php echo $linker ;?></a>

This worked, and now links are displayed properly:

Look at the code for HashMap#toString() and AbstractMap#toString() in the OpenJDK sources:

class java.util.HashMap.Entry<K,V> implements Map.Entry<K,V> {
       public final String toString() {
           return getKey() + "=" + getValue();
       }
   }
 class java.util.AbstractMap<K,V> {
     public String toString() {
         Iterator<Entry<K,V>> i = entrySet().iterator();
         if (! i.hasNext())
            return "{}";

        StringBuilder sb = new StringBuilder();
        sb.append('{');
        for (;;) {
            Entry<K,V> e = i.next();
            K key = e.getKey();
            V value = e.getValue();
            sb.append(key   == this ? "(this Map)" : key);
            sb.append('=');
            sb.append(value == this ? "(this Map)" : value);
            if (! i.hasNext())
                return sb.append('}').toString();
            sb.append(", ");
        }
    }
}

So if the guys from OpenJDK did not find a more elegant way to do this, there is none :-)

If you are working in a browser that doesn't support tabindex="-1", you may be able to get away with just giving the things that need to be skipped a really high tab index. For example tabindex="500" basically moves the object's tab order to the end of the page.

I did this for a long data entry form with a button thrown in the middle of it. It's not a button people click very often so I didn't want them to accidentally tab to it and press enter. disabled wouldn't work because it's a button.

There are a couple of ways to address your problem, however this is probably the most straightforward:

Your main method is static, so it does not have access to instance members (isLeapYear field and isLeapYear method. One approach to rectify this is to make both the field and the method static as well:

static boolean isLeapYear;
/* (snip) */
public static boolean isLeapYear(int year)
{
  /* (snip) */
}

Lastly, you're not actually calling your isLeapYear method (which is why you're not seeing any results). Add this line after int year = kboard.nextInt();:

isLeapYear(year);

That should be a start. There are some other best practices you could follow but for now just focus on getting your code to work; you can refactor later.

Try this one. It's simple, and since it's 2016 I am sure it will work on most browsers.

<textarea id="text" cols="50" rows="5" onkeyup="check()" maxlength="15"></textarea> 
<div><span id="spn"></span> characters left</div>

function check(){
    var string = document.getElementById("url").value
    var left = 15 - string.length;
    document.getElementById("spn").innerHTML = left;
}

To change the radio button color programmatically you can use following:

yourradio button name.buttonDrawable?.setColorFilter(Color.parseColor( color_value), PorterDuff.Mode.SRC_ATOP)

Same principle as Loki's answer but shorter. Just keep in mind that shorter doesn't automatically mean better.

dinner = Optional.ofNullable(cage.getChicken())
  .orElse(getFreerangeChicken());

Note: This usage of Optional is explicitly discouraged by the architects of the JDK and the designers of the Optional feature. You are allocating a fresh object and immediately throwing it away every time. But on the other hand it can be quite readable.

I totally agree with the guys, it's better to use virtualenv so you can set a custom environment for every project. It ideal for maintenance because it's like a different world for every project and every update of an application you make won't interfere with other projects.

Here you can find a nutshell of virtualenv related to installation and first steps.

The other answers are helpful, but the JSON in your question isn't valid. I have formatted it to make it clearer below, note the missing single quote on line 24.

There are a lot of great articles on how to manipulate objects in Javascript (whether using Node JS or a browser). I suggest here is a good place to start: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Working_with_Objects

You have a couple of options:

• You can add the path to the DLLs to the Executable files settings under Tools > Options > Projects and Solutions > VC++ Directories (but only for building, for executing or debugging here)
• You can add them in your global PATH environment variable
• You can start Visual Studio using a batch file as I described here and manipulate the path in that one
• You can copy the DLLs into the executable file's directory :-)

As indicated here https://stackoverflow.com/a/1632004/330867, you can implement it by "filtering" what is originating the exit of this page.

As mentionned in the comments, here's a new version of the code in the other question, which also include the ajax request you make in your question :

var canExit = true;

// For every function that will call an ajax query, you need to set the var "canExit" to false, then set it to false once the ajax is finished.

function checkCart() {
  canExit = false;
  $.ajax({
    url : 'index.php?route=module/cart/check',
    type : 'POST',
    dataType : 'json',
    success : function (result) {
       if (result) {
        canExit = true;
       }
    }
  })
}

$(document).on('click', 'a', function() {canExit = true;}); // can exit if it's a link
$(window).on('beforeunload', function() {
    if (canExit) return null; // null will allow exit without a question
    // Else, just return the message you want to display
    return "Do you really want to close?";
});

Important: You shouldn't have a global variable defined (here canExit), this is here for simpler version.

Note that you can't override completely the confirm message (at least in chrome). The message you return will only be prepended to the one given by Chrome. Here's the reason : How can I override the OnBeforeUnload dialog and replace it with my own?

Thank you all for your help, I added this code and it seems it fixed the issue:

The new Toolbar cannot be used for inflating multiple line objects, so it is impossible to add Tabs to it.
If you want to use a Toolbar like a TabWidget you can insert some Tab Objects to it, but only with the old Holo style.

Here there is a custom Library that uses v7 Toolbar like TabWidget with the new Material Design animations, but it uses the same methods from the old ActionBar Tabs, so you can attach your ViewPager to it.

It work's using rules instead of loaders

module : {
  rules : [
    {
      test : /\.jsx?/,
      include : APP_DIR,
      loader : 'babel-loader'
    }
  ]
}

Let's try this way:

select 
    a.ip, 
    a.os, 
    a.hostname, 
    a.port, 
    a.protocol, 
    b.state
from a
left join b 
    on a.ip = b.ip 
        and a.port = b.port /*if you has to filter by columns from right table , then add this condition in ON clause*/
where a.somecolumn = somevalue /*if you have to filter by some column from left table, then add it to where condition*/

So, in where clause you can filter result set by column from right table only on this way:

...
where b.somecolumn <> (=) null

Since you have a leading / in your href, you are referencing a file that will be in the root-folder. In case you have your page in a folder on your computer, not serving it from a local webserver, the leading / will tell the browser to look in the root folder of your filesystem. So the browser expect the file to be at C:/favicon.ico or similar, which is probably not what you've expected.

If you have the favicon.ico in the same folder as the web page, you could just remove the leading slash, and the icon should be visible.

<link rel="shortcut icon" href="favicon.ico" />

Update:

As a debug option, your could try to add a tag that you know works. I borrowed this snippet from the StackOverflow source. Try replacing your link tag with this and see if you get the SO logo as your favicon.

<link rel="shortcut icon" 
      href="http://cdn.sstatic.net/stackoverflow/img/favicon.ico">

Update 2:

It appears that there is a bug reported on Chromium where the favicon isn't displayed if the file is loaded locally, without being served through a webserver.

I think this solve the problem :

boolean allOk = false;
try{
  q();
  allOk = true;
} finally {
  try {
     is.close();
  } catch (Exception e) {
     if(allOk) {
       throw new SomeException(e);
     }
  }
}

i was having this same issue with ie, then i inserted this meta tag and it allowed me to edit the borders in ie

It sounds like you need to create a wrapper around an instance you can invalidate:

public class Ref<T> where T : class
{
    private T instance;
    public Ref(T instance)
    {
        this.instance = instance;
    }

    public static implicit operator Ref<T>(T inner)
    {
        return new Ref<T>(inner);
    }

    public void Delete()
    {
        this.instance = null;
    }

    public T Instance
    {
        get { return this.instance; }
    }
}

and you can use it like:

Ref<Car> carRef = new Car();
carRef.Delete();
var car = carRef.Instance;     //car is null

Be aware however that if any code saves the inner value in a variable, this will not be invalidated by calling Delete.

I recently ran into the same thing, and suggest this function for MSTest:

public bool AssertThrows(Action action) where T : Exception
{
    try {action();
}
catch(Exception exception)
{
    if (exception.GetType() == typeof(T))
        return true;
}
    return false;
}

Usage:

Assert.IsTrue(AssertThrows<FormatException>(delegate{ newMyMethod(MyParameter); }));

There is more in Assert that a particular exception has occured (Assert.Throws in MSTest).

for (Map.Entry<String, Tab> entry : hash.entrySet()) {
    String key = entry.getKey();
    Tab tab = entry.getValue();
    // do something with key and/or tab
}

Works like a charm.

You missed the each= argument to rep():

R> n <- 3
R> rep(1:5, each=n)
 [1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5
R> 

so your example can be done with a simple

R> rep(1:8, each=20)

You are looking for the window.scrollTop() function.

$(window).scroll(function() {
    var height = $(window).scrollTop();

    if(height  > some_number) {
        // do something
    }
});

You could look into using BrowserStack: http://www.browserstack.com

While not free, it is rather cheap. It allows you to test against several iOS versions on both iPhone and iPad, along with Android, and various desktop browsers and OSs. It has proved quite invaluable to my workplace for doing just these sort of tests.

echo $string = str_replace( array( '-', '.' ), '', $string);

 api.com/users?ids[]=id1&ids[]=id2&ids[]=id3&ids[]=id4&ids[]=id5

IMO, above calls does not looks RESTful, however these are quick and efficient workaround (y). But length of the URL is limited by webserver, eg tomcat.

RESTful attempt:

POST http://example.com/api/batchtask

   [
    {
      method : "GET",
      headers : [..],
      url : "/users/id1"
    },
    {
      method : "GET",
      headers : [..],
      url : "/users/id2"
    }
   ]

Server will reply URI of newly created batchtask resource.

201 Created
Location: "http://example.com/api/batchtask/1254"

Now client can fetch batch response or task progress by polling

GET http://example.com/api/batchtask/1254

This is how others attempted to solve this issue:

Since some of the other answers include info on rebuilding, and my use case also required a rebuild, I had a better solution (compared to those).

There's still a way to easily target just the one single worker container that both rebuilds + restarts it in a single line, albeit it's not actually a single command. The best solution for me was simply rebuild and restart:

docker-compose build worker && docker-compose restart worker

This accomplishes both major goals at once for me:

1. Targets the single worker container
2. Rebuilds and restarts it in a single line

Hope this helps anyone else getting here.

Just use dt.Clear()

Also you can set your TableAdapter/DataAdapter to clear before it fills with data.

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

It's all a perceptual thing. Git is generally rather good at recognising moves, because GIT is a content tracker

All that really depends is how your "stat" displays it. The only difference here is the -M flag.

git log --stat -M

Handling Errors

A sort of an "older style" of error handling is available to us in VBScript, that does make use of On Error Resume Next. First we enable that (often at the top of a file; but you may use it in place of the first Err.Clear below for their combined effect), then before running our possibly-error-generating code, clear any errors that have already occurred, run the possibly-error-generating code, and then explicitly check for errors:

On Error Resume Next
' ...
' Other Code Here (that may have raised an Error)
' ...
Err.Clear      ' Clear any possible Error that previous code raised
Set myObj = CreateObject("SomeKindOfClassThatDoesNotExist")
If Err.Number <> 0 Then
    WScript.Echo "Error: " & Err.Number
    WScript.Echo "Error (Hex): " & Hex(Err.Number)
    WScript.Echo "Source: " &  Err.Source
    WScript.Echo "Description: " &  Err.Description
    Err.Clear             ' Clear the Error
End If
On Error Goto 0           ' Don't resume on Error
WScript.Echo "This text will always print."

Above, we're just printing out the error if it occurred. If the error was fatal to the script, you could replace the second Err.clear with WScript.Quit(Err.Number).

Also note the On Error Goto 0 which turns off resuming execution at the next statement when an error occurs.

If you want to test behavior for when the Set succeeds, go ahead and comment that line out, or create an object that will succeed, such as vbscript.regexp.

The On Error directive only affects the current running scope (current Sub or Function) and does not affect calling or called scopes.

Raising Errors

If you want to check some sort of state and then raise an error to be handled by code that calls your function, you would use Err.Raise. Err.Raise takes up to five arguments, Number, Source, Description, HelpFile, and HelpContext. Using help files and contexts is beyond the scope of this text. Number is an error number you choose, Source is the name of your application/class/object/property that is raising the error, and Description is a short description of the error that occurred.

If MyValue <> 42 Then
    Err.Raise(42, "HitchhikerMatrix", "There is no spoon!")
End If

You could then handle the raised error as discussed above.

DZinX's answer is a great answer for the question. I found this question and used DZinX's answer while looking for the inverse function: convert dates with the julian day-of-year into the datetimes.

I found this to work:

import datetime
datetime.datetime.strptime('1936-077T13:14:15','%Y-%jT%H:%M:%S')

>>>> datetime.datetime(1936, 3, 17, 13, 14, 15)

datetime.datetime.strptime('1936-077T13:14:15','%Y-%jT%H:%M:%S').timetuple().tm_yday

>>>> 77

Or numerically:

import datetime
year,julian = [1936,77]
datetime.datetime(year, 1, 1)+datetime.timedelta(days=julian -1)

>>>> datetime.datetime(1936, 3, 17, 0, 0)

Or with fractional 1-based jdates popular in some domains:

jdate_frac = (datetime.datetime(1936, 3, 17, 13, 14, 15)-datetime.datetime(1936, 1, 1)).total_seconds()/86400+1
display(jdate_frac)

>>>> 77.5515625

year,julian = [1936,jdate_frac]
display(datetime.datetime(year, 1, 1)+datetime.timedelta(days=julian -1))

>>>> datetime.datetime(1936, 3, 17, 13, 14, 15)

I'm not sure of etiquette around here, but I thought a pointer to the inverse functionality might be useful for others like me.

public void SomeMethod(List<DateTime> dates)
{
    // do something
}

If you use docker-compose just set UPLOAD_LIMIT

phpmyadmin:
    image: phpmyadmin/phpmyadmin

1. Open your favorite text editor
2. Create a new file named whatever.h
3. Put your function prototypes in it

DONE.

Example whatever.h

#ifndef WHATEVER_H_INCLUDED
#define WHATEVER_H_INCLUDED
int f(int a);
#endif

Note: include guards (preprocessor commands) added thanks to luke. They avoid including the same header file twice in the same compilation. Another possibility (also mentioned on the comments) is to add #pragma once but it is not guaranteed to be supported on every compiler.

Example whatever.c

#include "whatever.h"

int f(int a) { return a + 1; }

And then you can include "whatever.h" into any other .c file, and link it with whatever.c's object file.

Like this:

sample.c

#include "whatever.h"

int main(int argc, char **argv)
{
    printf("%d\n", f(2)); /* prints 3 */
    return 0;
}

To compile it (if you use GCC):

$ gcc -c whatever.c -o whatever.o
$ gcc -c sample.c -o sample.o

To link the files to create an executable file:

$ gcc sample.o whatever.o -o sample

You can test sample:

$ ./sample

For me I had reached the maximum numbers of files a user can own

Check your numbers with quota -s and that the number under files is not too close to the quota

You could try to split on (?<=\D)(?=\d)|(?<=\d)(?=\D), like:

str.split("(?<=\\D)(?=\\d)|(?<=\\d)(?=\\D)");

It matches positions between a number and not-a-number (in any order).

• (?<=\D)(?=\d) - matches a position between a non-digit (\D) and a digit (\d)
• (?<=\d)(?=\D) - matches a position between a digit and a non-digit.

Here's my implementation, behaving like the built-in string functions in libc (that is, it expects a c-string, it modifies it and returns it to the caller).

It trims leading spaces & shifts the remaining chars to the left, as it parses the string from left to right. It then marks a new end of string and starts parsing it backwards, replacing trailing spaces with '\0's until it finds either a non-space char or the start of the string. I believe those are the minimum possible iterations for this particular task.

// ----------------------------------------------------------------------------
// trim leading & trailing spaces from string s (return modified string s)
// alg:
// - skip leading spaces, via cp1
// - shift remaining *cp1's to the left, via cp2
// - mark a new end of string
// - replace trailing spaces with '\0', via cp2
// - return the trimmed s
//
char *s_trim(char *s)
{
    char *cp1;                              // for parsing the whole s
    char *cp2;                              // for shifting & padding

    // skip leading spaces, shift remaining chars
    for (cp1=s; isspace(*cp1); cp1++ )      // skip leading spaces, via cp1
        ;
    for (cp2=s; *cp1; cp1++, cp2++)         // shift left remaining chars, via cp2
        *cp2 = *cp1;
    *cp2-- = 0;                             // mark new end of string for s

    // replace trailing spaces with '\0'
    while ( cp2 > s && isspace(*cp2) )
        *cp2-- = 0;                         // pad with '\0's

    return s;
}

I have modified your jsfiddle, can make top most module as rootModule for rest of the modules. Below Modifications updated on your jsfiddle.

1. Second Module can injected in RootModule.
2. In Html second defined ng-app placed inside the Root ng-app.
