The case is like :

 mysql connects will localhost when network is not up.
 mysql cannot connect when network is up.

You can try the following steps to diagnose and resolve the issue (my guess is that some other service is blocking port on which mysql is hosted):

1. Disconnect the network.
2. Stop mysql service (if windows, try from services.msc window)
3. Connect to network.
4. Try to start the mysql and see if it starts correctly.
5. Check for system logs anyways to be sure that there is no error in starting mysql service.
6. If all goes well try connecting.
7. If fails, try to do a telnet localhost 3306 and see what output it shows.
8. Try changing the port on which mysql is hosted, default 3306, you can change to some other port which is ununsed.

This should ideally resolve the issue you are facing.

Ahh, it is really simple

just add

white-space:pre-wrap;

to your displaying element css

I mean if you are showing result using <p> then your css should be

p{
   white-space:pre-wrap;
}

You need to analyze the JSON calls using Wireshark, so you will see if you include the charset in the formation of the JSON page or not, for example:

• If the page is simple if text / html

0000  48 54 54 50 2f 31 2e 31  20 32 30 30 20 4f 4b 0d   HTTP/1.1  200 OK.

• If the page is of the type including custom JSON with MIME "charset = ISO-8859-1"

0000  48 54 54 50 2f 31 2e 31  20 32 30 30 20 4f 4b 0d   HTTP/1.1  200 OK.

Why is that? because we can not put on the page of JSON a goal like this:

In my case I use the manufacturer Connect Me 9210 Digi:

• I had to use a flag to indicate that one would use non-standard MIME: p-> theCgiPtr-> = fDataType eRpDataTypeOther;
• It added the new MIME in the variable: strcpy (p-> theCgiPtr-> fOtherMimeType, "text / html; charset = ISO-8859-1 ");

It worked for me without having to convert the data passed by JSON for UTF-8 and then redo the conversion on the page ...

On invoking overridable method from constructors

Simply put, this is wrong because it unnecessarily opens up possibilities to MANY bugs. When the @Override is invoked, the state of the object may be inconsistent and/or incomplete.

A quote from Effective Java 2nd Edition, Item 17: Design and document for inheritance, or else prohibit it:

There are a few more restrictions that a class must obey to allow inheritance. Constructors must not invoke overridable methods, directly or indirectly. If you violate this rule, program failure will result. The superclass constructor runs before the subclass constructor, so the overriding method in the subclass will be invoked before the subclass constructor has run. If the overriding method depends on any initialization performed by the subclass constructor, the method will not behave as expected.

Here's an example to illustrate:

public class ConstructorCallsOverride {
    public static void main(String[] args) {

        abstract class Base {
            Base() {
                overrideMe();
            }
            abstract void overrideMe(); 
        }

        class Child extends Base {

            final int x;

            Child(int x) {
                this.x = x;
            }

            @Override
            void overrideMe() {
                System.out.println(x);
            }
        }
        new Child(42); // prints "0"
    }
}

Here, when Base constructor calls overrideMe, Child has not finished initializing the final int x, and the method gets the wrong value. This will almost certainly lead to bugs and errors.

On object construction with many parameters

Constructors with many parameters can lead to poor readability, and better alternatives exist.

Here's a quote from Effective Java 2nd Edition, Item 2: Consider a builder pattern when faced with many constructor parameters:

Traditionally, programmers have used the telescoping constructor pattern, in which you provide a constructor with only the required parameters, another with a single optional parameters, a third with two optional parameters, and so on...

The telescoping constructor pattern is essentially something like this:

public class Telescope {
    final String name;
    final int levels;
    final boolean isAdjustable;

    public Telescope(String name) {
        this(name, 5);
    }
    public Telescope(String name, int levels) {
        this(name, levels, false);
    }
    public Telescope(String name, int levels, boolean isAdjustable) {       
        this.name = name;
        this.levels = levels;
        this.isAdjustable = isAdjustable;
    }
}

And now you can do any of the following:

new Telescope("X/1999");
new Telescope("X/1999", 13);
new Telescope("X/1999", 13, true);

You can't, however, currently set only the name and isAdjustable, and leaving levels at default. You can provide more constructor overloads, but obviously the number would explode as the number of parameters grow, and you may even have multiple boolean and int arguments, which would really make a mess out of things.

As you can see, this isn't a pleasant pattern to write, and even less pleasant to use (What does "true" mean here? What's 13?).

Bloch recommends using a builder pattern, which would allow you to write something like this instead:

Telescope telly = new Telescope.Builder("X/1999").setAdjustable(true).build();

Note that now the parameters are named, and you can set them in any order you want, and you can skip the ones that you want to keep at default values. This is certainly much better than telescoping constructors, especially when there's a huge number of parameters that belong to many of the same types.

Related questions

• When would you use the Builder Pattern?
• Is this a well known design pattern? What is its name?

You can use the 'netstat' command for this. There's a description of doing this sort of thing here.

Immediately after your execute statement you can have an if statement. For example

ResultSet rs = statement.execute();
if (!rs.next()){
//ResultSet is empty
}

If you really need to check then it's better to use abstract base classes rather than concrete classes. For an integer that would mean:

>>> import numbers
>>> isinstance(3, numbers.Integral)
True

This doesn't restrict the check to just int, or just int and long, but also allows other user-defined types that behave as integers to work.

/// <summary>
/// Method return a read-only collection of the names of the constants in specified enum
/// </summary>
/// <returns></returns>
public static ReadOnlyCollection<string> GetNames()
{
    return Enum.GetNames(typeof(T)).Cast<string>().ToList().AsReadOnly();   
}

where T is a type of Enumeration; Add this:

using System.Collections.ObjectModel; 

In Objective-C, a @synchronized block handles locking and unlocking (as well as possible exceptions) automatically for you. The runtime dynamically essentially generates an NSRecursiveLock that is associated with the object you're synchronizing on. This Apple documentation explains it in more detail. This is why you're not seeing the log messages from your NSLock subclass — the object you synchronize on can be anything, not just an NSLock.

Basically, @synchronized (...) is a convenience construct that streamlines your code. Like most simplifying abstractions, it has associated overhead (think of it as a hidden cost), and it's good to be aware of that, but raw performance is probably not the supreme goal when using such constructs anyway.

You could try using json-lib's JSONAssert class:

JSONAssert.assertEquals(
  "{foo: 'bar', baz: 'qux'}",
  JSONObject.fromObject("{foo: 'bar', baz: 'xyzzy'}")
);

Gives:

junit.framework.ComparisonFailure: objects differed at key [baz]; expected:<[qux]> but was:<[xyzzy]>

You can utilize the dependency management mechanism.

If you create entries in the <dependencyManagement> section of your pom for spring-security-web and spring-web with the desired 3.1.0 version set the managed version of the artifact will override those specified in the transitive dependency tree.

I'm not sure if that really saves you any code, but it is a cleaner solution IMO.

Just adding on more details around InformationHiding, found This link is really good source with examples

InformationHiding is the idea that a design decision should be hidden from the rest of the system to prevent unintended coupling. InformationHiding is a design principle. InformationHiding should inform the way you encapsulate things, but of course it doesn't have to.

Encapsulation is a programming language feature.

If a program forgets to free a few Megabytes before it exits the operating system will free them. But if your program runs for weeks at a time and a loop inside the program forgets to free a few bytes in each iteration you will have a mighty memory leak that will eat up all the available memory in your computer unless you reboot it on a regular basis => even small memory leaks might be bad if the program is used for a seriously big task even if it originally wasn't designed for one.

plt.errorbar can be used to plot x, y, error data (as opposed to the usual plt.plot)

import matplotlib.pyplot as plt
import numpy as np

x = np.array([1, 2, 3, 4, 5])
y = np.power(x, 2) # Effectively y = x**2
e = np.array([1.5, 2.6, 3.7, 4.6, 5.5])

plt.errorbar(x, y, e, linestyle='None', marker='^')

plt.show()

plt.errorbar accepts the same arguments as plt.plot with additional yerr and xerr which default to None (i.e. if you leave them blank it will act as plt.plot).

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

Font awesome is just a font so you can use the font size attribute in your CSS to change the size of the icon.

So you can just add a class to the icon like this:

.big-icon {
    font-size: 32px;
}

For moving a virtual machine you need not clone the VM, just copy the VM files (after powering the VM off) to external HDD and register the same on destination host.

the ansible doc is quite clear https://docs.ansible.com/ansible/latest/collections/ansible/builtin/copy_module.html for parameter src it says the following:

Local path to a file to copy to the remote server.
This can be absolute or relative.
If path is a directory, it is copied recursively. In this case, if path ends with "/", 
only inside contents of that directory are copied to destination. Otherwise, if it 
does not end with "/", the directory itself with all contents is copied. This behavior 
is similar to the rsync command line tool.

So what you need is skip the / at the end of your src path.

  copy: src=/home/vagrant/dist dest=/usr/share/nginx/html/

pd.wide_to_long

You can add a prefix to your year columns and then feed directly to pd.wide_to_long. I won't pretend this is efficient, but it may in certain situations be more convenient than pd.melt, e.g. when your columns already have an appropriate prefix.

df.columns = np.hstack((df.columns[:2], df.columns[2:].map(lambda x: f'Value{x}')))

res = pd.wide_to_long(df, stubnames=['Value'], i='name', j='Date').reset_index()\
        .sort_values(['location', 'name'])

print(res)

   name        Date location  Value
0  test    Jan-2010        A     12
2  test    Feb-2010        A     20
4  test  March-2010        A     30
1   foo    Jan-2010        B     18
3   foo    Feb-2010        B     20
5   foo  March-2010        B     25

Think of a jar file as the root of a directory structure. Yes, you need to add them all separately.

Like this.

import java.util.Date;
import java.util.GregorianCalendar;

/**
 * DateDiff -- compute the difference between two dates.
 */
public class DateDiff {
  public static void main(String[] av) {
    /** The date at the end of the last century */
    Date d1 = new GregorianCalendar(2000, 11, 31, 23, 59).getTime();

    /** Today's date */
    Date today = new Date();

    // Get msec from each, and subtract.
    long diff = today.getTime() - d1.getTime();

    System.out.println("The 21st century (up to " + today + ") is "
        + (diff / (1000 * 60 * 60 * 24)) + " days old.");
  }

}

Here is an article on Java date arithmetic.

use this to convert string to datetime:

Datetime DT = DateTime.ParseExact(STRDATE,"dd/MM/yyyy",System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat)

If the string was constructed in the same program, I would recommend using this:

String newline = System.getProperty("line.separator");
boolean hasNewline = word.contains(newline);

But if you are specced to use \n, this driver illustrates what to do:

class NewLineTest {
    public static void main(String[] args) {
        String hasNewline = "this has a newline\n.";
        String noNewline = "this doesn't";

        System.out.println(hasNewline.contains("\n"));
        System.out.println(hasNewline.contains("\\n"));
        System.out.println(noNewline.contains("\n"));
        System.out.println(noNewline.contains("\\n"));

    }

}

Resulted in

true
false
false
false

In reponse to your comment:

class NewLineTest {
    public static void main(String[] args) {
        String word = "test\n.";
        System.out.println(word.length());
        System.out.println(word);
        word = word.replace("\n","\n ");
        System.out.println(word.length());
        System.out.println(word);

    }

}

Results in

test
.
7
test

Tensorflow provides an op to automatically apply an exponential decay to a learning rate tensor: tf.train.exponential_decay. For an example of it in use, see this line in the MNIST convolutional model example. Then use @mrry's suggestion above to supply this variable as the learning_rate parameter to your optimizer of choice.

The key excerpt to look at is:

# Optimizer: set up a variable that's incremented once per batch and
# controls the learning rate decay.
batch = tf.Variable(0)

learning_rate = tf.train.exponential_decay(
  0.01,                # Base learning rate.
  batch * BATCH_SIZE,  # Current index into the dataset.
  train_size,          # Decay step.
  0.95,                # Decay rate.
  staircase=True)
# Use simple momentum for the optimization.
optimizer = tf.train.MomentumOptimizer(learning_rate,
                                     0.9).minimize(loss,
                                                   global_step=batch)

Note the global_step=batch parameter to minimize. That tells the optimizer to helpfully increment the 'batch' parameter for you every time it trains.

I would have thought that something like this would be much better, since you're adding a variable, so why not restrict access and make it cleaner? Your getter/setters should do what they say on the tin.

public abstract class ExternalScript extends Script {

    private String source;

    public void setSource(String file) {
        source = file;
    }

    public String getSource() {
        return source;
    }
}

Bringing this back to the question, do you ever bother looking at where the getter/setter code is when reading it? If they all do getting and setting then you don't need to worry about what the function 'does' when reading the code. There are a few other reasons to think about too:

• If source was protected (so accessible by subclasses) then code gets messy: who's changing the variables? When it's an object it then becomes hard when you need to refactor, whereas a method tends to make this step easier.
• If your getter/setter methods aren't getting and setting, then describe them as something else.

Always think whether your class is really a different thing or not, and that should help decide whether you need anything more.

• Ruby require is more like "include" in other languages (such as C). It tells Ruby that you want to bring in the contents of another file. Similar mechanisms in other languages are:

  • using <namespace> directive in C#.
  • import <package> in Java.

• Ruby include is an object-oriented inheritance mechanism used for mixins.

There is a good explanation here:

[The] simple answer is that require and include are essentially unrelated.

"require" is similar to the C include, which may cause newbie confusion. (One notable difference is that locals inside the required file "evaporate" when the require is done.)

The Ruby include is nothing like the C include. The include statement "mixes in" a module into a class. It's a limited form of multiple inheritance. An included module literally bestows an "is-a" relationship on the thing including it.

You can also do any mathematical changes in the process or use MySQL functions to modify the values.

I have never had any luck with any scrollable content placed inside a stackpanel (anything derived from ScrollableContainer. The stackpanel has an odd layout mechanism that confuses child controls when the measure operation is completed and I found the vertical size ends up infinite, therefore not constrained - so it goes beyond the boundaries of the container and ends up clipped. The scrollbar doesn't show because the control thinks it has all the space in the world when it doesn't.

You should always place scrollable content inside a container that can resolve to a known height during its layout operation at runtime so that the scrollbars size appropriately. The parent container up in the visual tree must be able to resolve to an actual height, and this happens in the grid if you set the height of the RowDefinition o to auto or fixed.

This also happens in Silverlight.

This answer, based on another one (link at end), is about the difference between two dates.
You can see how it works because it's simple, also it includes splitting the difference into
units of time (a function that I made) and converting to UTC to stop time zone problems.

function date_units_diff(a, b, unit_amounts) {_x000D_
    var split_to_whole_units = function (milliseconds, unit_amounts) {_x000D_
        // unit_amounts = list/array of amounts of milliseconds in a_x000D_
        // second, seconds in a minute, etc., for example "[1000, 60]"._x000D_
        time_data = [milliseconds];_x000D_
        for (i = 0; i < unit_amounts.length; i++) {_x000D_
            time_data.push(parseInt(time_data[i] / unit_amounts[i]));_x000D_
            time_data[i] = time_data[i] % unit_amounts[i];_x000D_
        }; return time_data.reverse();_x000D_
    }; if (unit_amounts == undefined) {_x000D_
        unit_amounts = [1000, 60, 60, 24];_x000D_
    };_x000D_
    var utc_a = new Date(a.toUTCString());_x000D_
    var utc_b = new Date(b.toUTCString());_x000D_
    var diff = (utc_b - utc_a);_x000D_
    return split_to_whole_units(diff, unit_amounts);_x000D_
}_x000D_
_x000D_
// Example of use:_x000D_
var d = date_units_diff(new Date(2010, 0, 1, 0, 0, 0, 0), new Date()).slice(0,-2);_x000D_
document.write("In difference: 0 days, 1 hours, 2 minutes.".replace(_x000D_
   /0|1|2/g, function (x) {return String( d[Number(x)] );} ));

How my code above works

A date/time difference, as milliseconds, can be calculated using the Date object:

var a = new Date(); // Current date now.
var b = new Date(2010, 0, 1, 0, 0, 0, 0); // Start of 2010.

var utc_a = new Date(a.toUTCString());
var utc_b = new Date(b.toUTCString());
var diff = (utc_b - utc_a); // The difference as milliseconds.

Then to work out the number of seconds in that difference, divide it by 1000 to convert
milliseconds to seconds, then change the result to an integer (whole number) to remove
the milliseconds (fraction part of that decimal): var seconds = parseInt(diff/1000).
Also, I could get longer units of time using the same process, for example:
- (whole) minutes, dividing seconds by 60 and changing the result to an integer,
- hours, dividing minutes by 60 and changing the result to an integer.

I created a function for doing that process of splitting the difference into
whole units of time, named split_to_whole_units, with this demo:

console.log(split_to_whole_units(72000, [1000, 60]));
// -> [1,12,0] # 1 (whole) minute, 12 seconds, 0 milliseconds.

This answer is based on this other one.

If you have a class Car

public class Car {
    private Color externalColor;
}

And the property Color is a class

@Data
public class Color {
    private Integer id;
    private String name;
}

And you want to convert Color to an Enum

public class CarDTO {
    private ColorEnum externalColor;
}

Simply add a method in Color class to convert Color in ColorEnum

@Data
public class Color {
    private Integer id;
    private String name;

    public ColorEnum getEnum(){
        ColorEnum.getById(id);
    }
}

and inside ColorEnum implements the method getById()

public enum ColorEnum {
...
    public static ColorEnum getById(int id) {
        for(ColorEnum e : values()) {
            if(e.id==id) 
                return e;
        }
    }
}

Now you can use a classMap

private MapperFactory factory = new DefaultMapperFactory.Builder().build();
...
factory.classMap(Car.class, CarDTO.class)
    .fieldAToB("externalColor.enum","externalColor")
    .byDefault()
    .register();
...
CarDTO dto = mapper.map(car, CarDTO.class);

As everyone else has mentioned, the first task is to add the certificate to the Trusted Root Authority.

There is a custom exe (selfssl.exe) which will create a certificate and allow you to specify the Issued to: value (the URL). This means Internet explorer will validate the issued to url with the custom intranet url.

Make sure you restart Internet Explorer to refresh changes.

If you already have it as a DateTime, use:

string x = dt.ToString("yyyy-MM-dd");

See the MSDN documentation for more details. You can specify CultureInfo.InvariantCulture to enforce the use of Western digits etc. This is more important if you're using MMM for the month name and similar things, but it wouldn't be a bad idea to make it explicit:

string x = dt.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);

If you have a string to start with, you'll need to parse it and then reformat... of course, that means you need to know the format of the original string.

Here is a Perl script that prints out Git diff commands for a given file as found in a Git log command.

E.g.

git log pom.xml | perl gldiff.pl 3 pom.xml

Yields:

git diff 5cc287:pom.xml e8e420:pom.xml
git diff 3aa914:pom.xml 7476e1:pom.xml
git diff 422bfd:pom.xml f92ad8:pom.xml

which could then be cut and pasted in a shell window session or piped to /bin/sh.

Notes:

1. the number (3 in this case) specifies how many lines to print
2. the file (pom.xml in this case) must agree in both places (you could wrap it in a shell function to provide the same file in both places) or put it in a binary directory as a shell script

Code:

# gldiff.pl
use strict;

my $max  = shift;
my $file = shift;

die "not a number" unless $max =~ m/\d+/;
die "not a file"   unless -f $file;

my $count;
my @lines;

while (<>) {
    chomp;
    next unless s/^commit\s+(.*)//;
    my $commit = $1;
    push @lines, sprintf "%s:%s", substr($commit,0,6),$file;
    if (@lines == 2) {
        printf "git diff %s %s\n", @lines;
        @lines = ();
    }
    last if ++$count >= $max *2;
}

A string to char array is as simple as

String str = "someString"; 
char[] charArray = str.toCharArray();

Can you explain a little more on what you are trying to do?

* Update *

if I am understanding your new comment, you can use a byte array and example is provided.

byte[] bytes = ByteBuffer.allocate(4).putInt(1695609641).array();

for (byte b : bytes) {
   System.out.format("0x%x ", b);
}

With the following output

0x65 0x10 0xf3 0x29

I did so

Field in model:

[Required]
[Display(Name = "User name")]
public string UserName { get; set; }

Razor:

<li>
  @Html.TextBoxFor(m => m.UserName, new { placeholder = Html.DisplayNameFor(n => n.UserName)})
</li>

Encountered similar issue, my server is behind nginx. There's no error in web server's (Python flask) log, but some error messsage in nginx log.

[crit] 31054#31054: *269464 open() "/var/cache/nginx/proxy_temp/3/45/0000000453" failed (13: Permission denied) while reading upstream

I fixed this issue by correcting the permission of directory:

/var/cache/nginx

The easiest way for me is just like:

            try {
                FileWriter writer = new FileWriter("C:/Your/Absolute/Path/YourFile.txt");
                writer.write("Wow, this is so easy!");
                writer.close();
            } catch (IOException e) {
                e.printStackTrace();
            }

Useful tips & tricks:

• Give it a certain path:

  new FileWriter("C:/Your/Absolute/Path/YourFile.txt");

• New line

  writer.write("\r\n");

• Append lines into existing txt

  new FileWriter("log.txt");

Hope it works!

I discovered today that we can now debug Javascript With the developer tool bar plugins integreted in IE 8.

• Click ? Tools on the toolbar, to the right of the tabs.
• Select Developer Tools. The Developer Tools dialogue should open.
• Click the Script tab in the dialogue.
• Click the Start Debugging button.

You can use watch, breakpoint, see the call stack etc, similarly to debuggers in professional browsers.

You can also use the statement debugger; in your JavaScript code the set a breakpoint.

Use: Arrays.copyOf(yourArray,n);

It should just be

name[0].firstChild.nodeValue

I was getting this problem and I'm using Spring's RestTemplate on the client and Spring Web on the server. Both APIs have very poor error reporting, making them extremely difficult to develop with.

After many hours of trying all sorts of experiments I figured out that the issue was being caused by passing in a null reference for the POST body instead of the expected List. I presume that RestTemplate cannot determine the content-type from a null object, but doesn't complain about it. After adding the correct headers, I started getting a different server-side exception in Spring before entering my service method.

The fix was to pass in an empty List from the client instead of null. No headers are required since the default content-type is used for non-null objects.

if you want to apply separate css classes for same element with conditions in Vue.js you can use the below given method.it worked in my scenario.

html

 <div class="Main" v-bind:class="{ Sub: page}"  >

in here, Main and Sub are two different class names for same div element. v-bind:class directive is used to bind the sub class in here. page is the property we use to update the classes when it's value changed.

js

data:{
page : true;
}

here we can apply a condition if we needed. so, if the page property becomes true element will go with Main and Sub claases css styles. but if false only Main class css styles will be applied.

I solved this error using the bellow i get it from here

ionic cordova run browser will load those native plugins that support browser platform.

Maybe you should try it with -quality 100 -size "1024x1024", because resize often gives results that are ugly to view.

I know this is years later but I ran into the same problem. The solution I found was to change the window title in main.cpp. I guess once the w.show(); is called the window title can no longer be changed. In my case I just wanted the title to reflect the current directory and it works.

int main(int argc, char *argv[]) 
{
QApplication a(argc, argv);
MainWindow w;
w.setWindowTitle(QDir::currentPath());
w.show();

return a.exec();
}

Yes, use gzip for this. The best way is to read data as input and redirect the compressed to output file i.e.

cat test.csv | gzip > test.csv.gz

cat test.csv will send the data as stdout and using pipe-sign gzip will read that data as stdin. Make sure to redirect the gzip output to some file as compressed data will not be written to the terminal.

I think you should build a dataset/datatable in code and bind the grid to that.

Once I faced with the issue when I did not know which the element currently stored in my variable (svg or html) but I needed to get it width and height. I created this function and want to share it:

function computeDimensions(selection) {
  var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGGraphicsElement) { // check if node is svg element
    dimensions = node.getBBox();
  } else { // else is html element
    dimensions = node.getBoundingClientRect();
  }
  console.log(dimensions);
  return dimensions;
}

Little demo in the hidden snippet below. We handle click on the blue div and on the red svg circle with the same function.

var svg = d3.select('svg')
  .attr('width', 50)
  .attr('height', 50);

function computeDimensions(selection) {
    var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGElement) {
    dimensions = node.getBBox();
  } else {
    dimensions = node.getBoundingClientRect();
  }
  console.clear();
  console.log(dimensions);
  return dimensions;
}

var circle = svg
    .append("circle")
    .attr("r", 20)
    .attr("cx", 30)
    .attr("cy", 30)
    .attr("fill", "red")
    .on("click", function() { computeDimensions(circle); });
    
var div = d3.selectAll("div").on("click", function() { computeDimensions(div) });

* {
  margin: 0;
  padding: 0;
  border: 0;
}

body {
  background: #ffd;
}

.div {
  display: inline-block;

Basically in JDBC most of these properties are not configurable in the API like that, rather they depend on implementation. The way JDBC handles this is by allowing the connection URL to be different per vendor.

So what you do is register the driver so that the JDBC system can know what to do with the URL:

 DriverManager.registerDriver((Driver) Class.forName("com.mysql.jdbc.Driver").newInstance());

Then you form the URL:

 String url = "jdbc:mysql://[host][,failoverhost...][:port]/[database][?propertyName1][=propertyValue1][&propertyName2][=propertyValue2]"

And finally, use it to get a connection:

 Connection c = DriverManager.getConnection(url);

In more sophisticated JDBC, you get involved with connection pools and the like, and application servers often have their own way of registering drivers in JNDI and you look up a DataSource from there, and call getConnection on it.

In terms of what properties MySQL supports, see here.

EDIT: One more thought, technically just having a line of code which does Class.forName("com.mysql.jdbc.Driver") should be enough, as the class should have its own static initializer which registers a version, but sometimes a JDBC driver doesn't, so if you aren't sure, there is little harm in registering a second one, it just creates a duplicate object in memeory.

Here are the basics. I'm not sure that any of these count as "clear and simple" though.

And just what's wrong with sar? :)

public void Each<T>(IEnumerable<T> items, Action<T> action)
{
    foreach (var item in items)
        action(item);
}

... and call it thusly:

Each(myList, i => Console.WriteLine(i));

 private void MainTimesheetForm_Load(object sender, EventArgs e)
        {
            ListViewItem newList = new ListViewItem("1");
            newList.SubItems.Add("2");
            newList.SubItems.Add(DateTime.Now.ToLongTimeString());
            newList.SubItems.Add("3");
            newList.SubItems.Add("4");
            newList.SubItems.Add("5");
            newList.SubItems.Add("6");
            listViewTimeSheet.Items.Add(newList);

        }

Using @Marc Gravell 's answer, I found a way to use the following method:

source.TakeWhile(x => x != value).Count();

in order to get -1 when the item cannot be found:

internal static class Utils
{

    public static int IndexOf<T>(this IEnumerable<T> enumerable, T item) => enumerable.IndexOf(item, EqualityComparer<T>.Default);

    public static int IndexOf<T>(this IEnumerable<T> enumerable, T item, EqualityComparer<T> comparer)
    {
        int index = enumerable.TakeWhile(x => comparer.Equals(x, item)).Count();
        return index == enumerable.Count() ? -1 : index;
    }
}

I guess this way could be both the fastest and the simpler. However, I've not tested performances yet.

You can change build versiyon.For example i tried QT 5.6.1 but it didn't work.Than i tried QT 5.7.0 .So it worked , Good Luck! :)

Had a similar issue. But it is important to understand the root cause and it may vary for different use cases.

Scenario 1
You are trying to decrypt a value which was not encoded correctly in the first place.

byte[] encryptedBytes = Base64.decodeBase64(encryptedBase64String);

If the String is misconfigured for certain reason or has not been encoded correctly, you would see the error " Input length must be multiple of 16 when decrypting with padded cipher"

Scenario 2
Now if by any chance you are using this encoded string in url (trying to pass in the base64Encoded value in url, it will fail. You should do URLEncoding and then pass in the token, it will work.

Scenario 3
When integrating with one of the vendors, we found that we had to do encryption of Base64 using URLEncoder but then we need not decode it because it was done internally by the Vendor

UrlConnection is an awkward API to work with. HttpClient is by far the better API and it'll spare you from loosing time searching how to achieve certain things like this stackoverflow question illustrates perfectly. I write this after having used the jdk HttpUrlConnection in several REST clients. Furthermore when it comes to scalability features (like threadpools, connection pools etc.) HttpClient is superior

When using the .html() method, a htmlString must be the parameter. (source) Put your string inside a HTML tag and it should work or use .text() as suggested by farzad.

Example:

<div class="demo-container">
    <div class="demo-box">Demonstration Box</div>
</div>

<script type="text/javascript">
$("div.demo-container").html( "<p>All new content. <em>You bet!</em></p>" );
</script>

Meaning the 2nd parameter('master') of the "git push" command -

$ git push origin master

can be made clear by initiating "push" command from 'news-item' branch. It caused local "master" branch to be pushed to the remote 'master' branch. For more information refer

https://git-scm.com/docs/git-push

where <refspec> in

[<repository> [<refspec>…?]

is written to mean "specify what destination ref to update with what source object."

For your reference, here is a screen capture how I verified this statement.

along with these two variants, there is also jade.renderFile which generates html that need not be passed to the client.

usage-

var jade = require('jade');

exports.getJson = getJson;

function getJson(req, res) {
    var html = jade.renderFile('views/test.jade', {some:'json'});
    res.send({message: 'i sent json'});
}

getJson() is available as a route in app.js.

Separation of presentation and data drives my commit messages here.

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

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

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

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

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

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

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

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

You can use Calendar.getActualMaximum method:

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, month-1);
int numDays = calendar.getActualMaximum(Calendar.DATE);

And month-1 is Because of month takes its original number of month while in method takes argument as below in Calendar.class

public int getActualMaximum(int field) {
   throw new RuntimeException("Stub!");
}

And the (int field) is like as below.

public static final int JANUARY = 0;
public static final int NOVEMBER = 10;
public static final int DECEMBER = 11;

From the docs of the flush method:

Flushes the output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

The buffering is mainly done to improve the I/O performance. More on this can be read from this article: Tuning Java I/O Performance.

string[] lines = File.ReadLines("c:\\file.txt").ToArray();

Although one wonders why you'll want to do that when ReadAllLines works just fine.

Or perhaps you just want to enumerate with the return value of File.ReadLines:

var lines = File.ReadAllLines("c:\\file.txt");
foreach (var line in lines)
{
    Console.WriteLine("\t" + line);
}

/^(?:(25[0-5]|2[0-4]\d|1\d\d|[1-9]\d|\d)\.){3}(?1)$/m

The easiest way without fiddling with command line:

1. launch Xcode once.
2. run ios simulator
3. drag the ios simulator icon to dock it.

Next time you want to use it, just click on the ios simulator icon in the dock.

                            my text 1.
                        </p>
                    </li>
                    <li>
                        <p>
                            my text 2.
                        </p>
                    </li>
                </ol>
            </li>
        </ol>

just add ToList() method to end of your list, where bind to datagridview DataSource:

dataGridView1.DataSource = MyList.ToList();

If you change the ManagementObjectSearcher to the following:

ManagementObjectSearcher searcher = 
       new ManagementObjectSearcher("root\\CIMV2", 
       @"SELECT * FROM Win32_PnPEntity where DeviceID Like ""USB%"""); 

So the "GetUSBDevices() looks like this"

static List<USBDeviceInfo> GetUSBDevices()
{
  List<USBDeviceInfo> devices = new List<USBDeviceInfo>();

  ManagementObjectCollection collection;
  using (var searcher = new ManagementObjectSearcher(@"SELECT * FROM Win32_PnPEntity where DeviceID Like ""USB%"""))
    collection = searcher.Get();      

  foreach (var device in collection)
  {
    devices.Add(new USBDeviceInfo(
    (string)device.GetPropertyValue("DeviceID"),
    (string)device.GetPropertyValue("PNPDeviceID"),
    (string)device.GetPropertyValue("Description")
    ));
  }

  collection.Dispose();
  return devices;
}

}

Your results will be limited to USB devices (as opposed to all types on your system)

Wow, that was easier than I thought:

git checkout -b newbranch v1.0

You might be interested in the calc approach:

font-size: calc(4vw + 4vh + 2vmin);

done. Tweak values till matches your taste.

I like

if ('string'[/^str/]) ...

If you want to get the date like 12-3-2016, separate each day, month, and year value, then copy-paste this code:

$day = date("d");
$month = date("m");
$year = date("y");
print "date" . $day . "-" . $month . "-" . $year;

on socket.io 1.3 i've accomplished this in 2 lines

var usersSocketIds = Object.keys(chat.adapter.rooms['room name']);
var usersAttending = _.map(usersSocketIds, function(socketClientId){ return chat.connected[socketClientId] })

From the ECMAScript specification, Section 11.9.3 The Abstract Equality Comparison Algorithm:

The comparison x == y, where x and y are values, produces true or false. Such a comparison is performed as follows:

• If Type(y) is Boolean, return the result of the comparison x == ToNumber(y).

Thus, in, if (1 == true), true gets coerced to a Number, i.e. Number(true), which results in the value of 1, yielding the final if (1 == 1) which is true.

if (0 == false) is the exact same logic, since Number(false) == 0.

This doesn't happen when you use the strict equals operator === instead:

11.9.6 The Strict Equality Comparison Algorithm

The comparison x === y, where x and y are values, produces true or false. Such a comparison is performed as follows:

• If Type(x) is different from Type(y), return false.

I usually open them with 7-Zip... It allows at least to see packages and classes and resources.
Should I need to see methods or fields, I would use Jad but of course, it is better to rely on (good) JavaDoc...

Now, somewhere on SO was mentioned some Eclipse plug-ins, to find in which jar file a class is located, perhaps they can do more (ie. what you requested).

[EDIT] Reference to SO thread. Not what is asked, but somehow related, thus useful: Java: How do I know which jar file to use given a class name?

Most people advise against using global variables. If you want the same logger class in different modules you can do this

logger.js

  module.exports = new logger(customConfig);

foobar.js

  var logger = require('./logger');
  logger('barfoo');

If you do want a global variable you can do:

global.logger = new logger(customConfig);

This is the simplest variant: just use array of integers....

 <li ng-repeat="n in [1,2,3,4,5]">test {{n}}</li>

I use layers to describe the architect or technology stack within a component of my solutions. I use tiers to logically group those components typically when network or interprocess communication is involved.

Handling bytes and unsigned integers with BigInteger:

byte[] b = ...                    // your integer in big-endian
BigInteger ui = new BigInteger(b) // let BigInteger do the work
int i = ui.intValue()             // unsigned value assigned to i

I had the same problem with one of my projects, however, none of the above helped to solve the warning. I checked the detailed build logfile, I used AsmSpy to verify that I used the correct versions for each project in the affected solution, I double checked the actual entries in each project file - nothing helped.

Eventually it turned out that the problem was a nested dependency of one of the references I had in one project. This reference (A) in turn required a different version of (B) which was referenced directly from all other projects in my solution. Updating the reference in the referenced project solved it.

Solution A
+--Project A
   +--Reference A (version 1.1.0.0)
   +--Reference B
+--Project B
   +--Reference A (version 1.1.0.0)
   +--Reference B
   +--Reference C
+--Project C
   +--Reference X (this indirectly references Reference A, but with e.g. version 1.1.1.0)

Solution B
+--Project A
   +--Reference A (version 1.1.1.0)

I hope the above shows what I mean, took my a couple of hours to find out, so hopefully someone else will benefit as well.

There's nothing here explaining the use of multiple variables, so I'll chuck it in just incase someone needs it in the future.

You need to concatenate multiple variables:

header('Location: http://linkhere.com?var1='.$var1.'&var2='.$var2.'&var3'.$var3);

It depends on the specific use case.

If your table is static and only has a short list of values (and there is just a small chance that this would change during a lifetime of DB), I would recommend this construction:

CREATE TABLE Foo 
(
    FooCode VARCHAR(16), -- short code or shortcut, but with some meaning.
    Name NVARCHAR(128), -- full name of entity, can be used as fallback in case when your localization for some language doesn't exist
    LocalizationCode AS ('Foo.' + FooCode) -- This could be a code for your localization table... 
)

Of course, when your table is not static at all, using INT as primary key is the best solution.

try this..

<tr ng-repeat='item in items'>
<td>{{item.Name}}</td>
<td>{{item.Price}}</td>
<td>{{item.Quantity}}</td>
</tr>

It seems some what center of the screen. So I would like to do like this

body { 
     background: url('http://oi44.tinypic.com/33tjudk.jpg') no-repeat center center fixed;    
     background-size:cover; 
     text-align: 0 auto; // Make the play button horizontal center
}

#play_button {
    position:absolute;  // absolutely positioned
    transition: .5s ease;
    top: 50%;  // Makes vertical center
} 

For people who are still getting error despite of passing absolute path, should check that if file has a valid name. For me I was trying to create a file with '/' in the file name. As soon as I removed '/', I was able to create the file.

Most of the jQuery Ajax methods return an XMLHttpRequest (or the equivalent) object, so you can just use abort().

See the documentation:

• abort Method (MSDN). Cancels the current HTTP request.
• abort() (MDN). If the request has been sent already, this method will abort the request.

var xhr = $.ajax({
    type: "POST",
    url: "some.php",
    data: "name=John&location=Boston",
    success: function(msg){
       alert( "Data Saved: " + msg );
    }
});

//kill the request
xhr.abort()

UPDATE: As of jQuery 1.5 the returned object is a wrapper for the native XMLHttpRequest object called jqXHR. This object appears to expose all of the native properties and methods so the above example still works. See The jqXHR Object (jQuery API documentation).

UPDATE 2: As of jQuery 3, the ajax method now returns a promise with extra methods (like abort), so the above code still works, though the object being returned is not an xhr any more. See the 3.0 blog here.

UPDATE 3: xhr.abort() still works on jQuery 3.x. Don't assume the update 2 is correct. More info on jQuery Github repository.

Jython approach

Java is supposed to be platform independent, and to call a native application (like python) isn't very platform independent.

There is a version of Python (Jython) which is written in Java, which allow us to embed Python in our Java programs. As usually, when you are going to use external libraries, one hurdle is to compile and to run it correctly, therefore we go through the process of building and running a simple Java program with Jython.

We start by getting hold of jython jar file:

https://www.jython.org/download.html

I copied jython-2.5.3.jar to the directory where my Java program was going to be. Then I typed in the following program, which do the same as the previous two; take two numbers, sends them to python, which adds them, then python returns it back to our Java program, where the number is outputted to the screen:

import org.python.util.PythonInterpreter; 
import org.python.core.*; 

class test3{
    public static void main(String a[]){

        PythonInterpreter python = new PythonInterpreter();

        int number1 = 10;
        int number2 = 32;
        python.set("number1", new PyInteger(number1));
        python.set("number2", new PyInteger(number2));
        python.exec("number3 = number1+number2");
        PyObject number3 = python.get("number3");
        System.out.println("val : "+number3.toString());
    }
}

I call this file "test3.java", save it, and do the following to compile it:

javac -classpath jython-2.5.3.jar test3.java

The next step is to try to run it, which I do the following way:

java -classpath jython-2.5.3.jar:. test3

Now, this allows us to use Python from Java, in a platform independent manner. It is kind of slow. Still, it's kind of cool, that it is a Python interpreter written in Java.

DateTime Picker can be used to pick both date and time that is why it is called 'Date and Time Picker'. You can set the "Format" property to "Custom" and set combination of different format specifiers to represent/pick date/time in different formats in the "Custom Format" property. However if you want to change Date, then the pop-up calendar can be used whereas in case of Time selection (in the same control you are bound to use up/down keys to change values.

For example a custom format " ddddd, MMMM dd, yyyy hh:mm:ss tt " will give you a result like this : "Thursday, August 20, 2009 02:55:23 PM".

You can play around with different combinations for format specifiers to suit your need e.g MMMM will give "August" whereas MM will give "Aug"

for group headers/footers:

=iif(RunningValue(*group on field*,CountDistinct,"*parent group name*") Mod 2,"White","AliceBlue")

You can also use this to “reset” the row color count within each group. I wanted the first detail row in each sub group to start with White and this solution (when used on the detail row) allowed that to happen:

=IIF(RunningValue(Fields![Name].Value, CountDistinct, "NameOfPartnetGroup") Mod 2, "White", "Wheat")

See: http://msdn.microsoft.com/en-us/library/ms159136(v=sql.100).aspx

Try this. Note there's no database specified - it just runs "on the server"

psql -U postgres -c "drop database databasename"

If that doesn't work, I have seen a problem with postgres holding onto orphaned prepared statements.
To clean them up, do this:

SELECT * FROM pg_prepared_xacts;

then for every id you see, run this:

ROLLBACK PREPARED '<id>';

In your home directory, you should edit .bash_profile if you have Git for Windows 2.21.0 or later (as of this writing).

You could direct .bash_profile to just source .bashrc, but if something happens to your .bash_profile, then it will be unclear why your .bashrc is again not working.

I put all my aliases and other environment stuff in .bash_profile, and I also added this line:

echo "Sourcing ~/.bash_profile - this version of Git Bash doesn't use .bashrc"

And THEN, in .bashrc I have

echo "This version of Git Bash doesn't use .bashrc. Use .bash_profile instead"

(Building on @harsel's response. I woulda commented, but I have no points yet.)

Don't forget "compare with clipboard".

Something that I use all the time in IntelliJ and which has no equivalent in Eclipse.

I found the following command to run from command line:

vlc.exe --extraintf=http:logger --verbose=2 --file-logging --logfile=vlc-log.txt

I have come to point out the answer nobody seems to see here. You can fullfill all requests you have made with pure CSS and it's very simple. Just use Media Queries. Media queries can check the orientation of the user's screen, or viewport. Then you can style your images depending on the orientation.

Just set your default CSS on your images like so:

img {
   width:auto;
   height:auto;
   max-width:100%;
   max-height:100%;
}

Then use some media queries to check your orientation and that's it!

@media (orientation: landscape) { img { height:100%; } }
@media (orientation: portrait) { img { width:100%; } }

You will always get an image that scales to fit the screen, never loses aspect ratio, never scales larger than the screen, never clips or overflows.

To learn more about these media queries, you can read MDN's specs.

Centering

To center your image horizontally and vertically, just use the flex box model. Use a parent div set to 100% width and height, like so:

div.parent {
   display:flex;
   position:fixed;
   left:0px;
   top:0px;
   width:100%;
   height:100%;
   justify-content:center;
   align-items:center;
}

With the parent div's display set to flex, the element is now ready to use the flex box model. The justify-content property sets the horizontal alignment of the flex items. The align-items property sets the vertical alignment of the flex items.

Conclusion

I too had wanted these exact requirements and had scoured the web for a pure CSS solution. Since none of the answers here fulfilled all of your requirements, either with workarounds or settling upon sacrificing a requirement or two, this solution really is the most straightforward for your goals; as it fulfills all of your requirements with pure CSS.

EDIT: The accepted answer will only appear to work if your images are large. Try using small images and you will see that they can never be larger than their original size.

With dplyr it's now also possible to access a specific column of a dataframe by simply using double curly braces {{...}} around the desired column name within the function body, e.g. for col_name:

library(tidyverse)

fun <- function(df, col_name){
   df %>% 
     filter({{col_name}} == "test_string")
} 

select LAST_LOAD_TIME, ELAPSED_TIME, MODULE, SQL_TEXT elapsed from v$sql
  order by LAST_LOAD_TIME desc

More complicated example (don't forget to delete or to substitute PATTERN):

select * from (
  select LAST_LOAD_TIME, to_char(ELAPSED_TIME/1000, '999,999,999.000') || ' ms' as TIME,
         MODULE, SQL_TEXT from SYS."V_\$SQL"
    where SQL_TEXT like '%PATTERN%'
    order by LAST_LOAD_TIME desc
  ) where ROWNUM <= 5;

Boost.Regex is very good and is slated to become part of the C++0x standard (it's already in TR1).

Personally, I find Boost.Xpressive much nicer to work with. It is a header-only library and it has some nice features such as static regexes (regexes compiled at compile time).

Update: If you're using a C++11 compliant compiler (gcc 4.8 is NOT!), use std::regex unless you have good reason to use something else.

You can also press F1 to open the Command Palette and then remove the > via Backspace. Now you can search for files, too.

Here is a solution that will match the pattern against the full path and not just the base filename.

It uses fnmatch.translate to convert a glob-style pattern into a regular expression, which is then matched against the full path of each file found while walking the directory.

re.IGNORECASE is optional, but desirable on Windows since the file system itself is not case-sensitive. (I didn't bother compiling the regex because docs indicate it should be cached internally.)

import fnmatch
import os
import re

def findfiles(dir, pattern):
    patternregex = fnmatch.translate(pattern)
    for root, dirs, files in os.walk(dir):
        for basename in files:
            filename = os.path.join(root, basename)
            if re.search(patternregex, filename, re.IGNORECASE):
                yield filename

Because linux is a built-in macro defined when the compiler is running on, or compiling for (if it is a cross-compiler), Linux.

There are a lot of such predefined macros. With GCC, you can use:

cp /dev/null emptyfile.c
gcc -E -dM emptyfile.c

to get a list of macros. (I've not managed to persuade GCC to accept /dev/null directly, but the empty file seems to work OK.) With GCC 4.8.1 running on Mac OS X 10.8.5, I got the output:

That's 236 macros from an empty file. When I added #include <stdio.h> to the file, the number of macros defined went up to 505. These includes all sorts of platform-identifying macros.

If that helps anyone, (even if this is kind of poor as we must only allow this for dev purpose) here is a Java solution as I encountered the same issue. [Edit] Do not use the wild card * as it is a bad solution, use localhost if you really need to have something working locally.

public class SimpleCORSFilter implements Filter {

public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
    HttpServletResponse response = (HttpServletResponse) res;
    response.setHeader("Access-Control-Allow-Origin", "my-authorized-proxy-or-domain");
    response.setHeader("Access-Control-Allow-Methods", "POST, GET");
    response.setHeader("Access-Control-Max-Age", "3600");
    response.setHeader("Access-Control-Allow-Headers", "Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");
    chain.doFilter(req, res);
}

public void init(FilterConfig filterConfig) {}

public void destroy() {}

}

is just going to look for a div with class="outer inner", is that correct?

No, '.outer .inner' will look for all elements with the .inner class that also have an element with the .outer class as an ancestor. '.outer.inner' (no space) would give the results you're thinking of.

'.outer > .inner' will look for immediate children of an element with the .outer class for elements with the .inner class.

Both '.outer .inner' and '.outer > .inner' should work for your example, although the selectors are fundamentally different and you should be wary of this.

This worked for me:
chmod 700 .ssh chmod 600 .ssh/id_rsa chmod 644 .ssh/id_rsa.pub

Then, type this: ssh-add ~/.ssh/id_rsa

As Sqlite doesn't have a date type you will need to do string comparison to achieve this. For that to work you need to reverse the order - eg from dd/MM/yyyy to yyyyMMdd, using something like

where substr(column,7)||substr(column,4,2)||substr(column,1,2) 
      between '20101101' and '20101130'

clearfix is the same as overflow:hidden. Both clear floated children of the parent, but clearfix will not cut off the element which overflow to it's parent. It also works in IE8 & above.

There is no need to define "." in content & .clearfix. Just write like this:

.clr:after {
    clear: both;
    content: "";
    display: block;
}

HTML

<div class="parent clr"></div>

What methods of ‘clearfix’ can I use?

2.5X FASTER and MOST EFFECTIVE method than other's regular expressions methods:

/// <summary>
/// Returns a new string in which all occurrences of a specified string in the current instance are replaced with another 
/// specified string according the type of search to use for the specified string.
/// </summary>
/// <param name="str">The string performing the replace method.</param>
/// <param name="oldValue">The string to be replaced.</param>
/// <param name="newValue">The string replace all occurrences of <paramref name="oldValue"/>. 
/// If value is equal to <c>null</c>, than all occurrences of <paramref name="oldValue"/> will be removed from the <paramref name="str"/>.</param>
/// <param name="comparisonType">One of the enumeration values that specifies the rules for the search.</param>
/// <returns>A string that is equivalent to the current string except that all instances of <paramref name="oldValue"/> are replaced with <paramref name="newValue"/>. 
/// If <paramref name="oldValue"/> is not found in the current instance, the method returns the current instance unchanged.</returns>

    if (oldValue == null)
    {
        // Same as original .NET C# string.Replace behavior.
        throw new ArgumentNullException(nameof(oldValue));
    }

    int @charsUntilStringEnd = str.Length - startSearchFromIndex;
    resultStringBuilder.Append(str, startSearchFromIndex, @charsUntilStringEnd);


    return resultStringBuilder.ToString();

}

Note: ignore case == StringComparison.OrdinalIgnoreCase as parameter for StringComparison comparisonType. It is the fastest, case-insensitive way to replace all values.

Advantages of this method:

• High CPU and MEMORY efficiency;
• It is the fastest solution, 2.5 times faster than other's methods with regular expressions (proof in the end);
• Suitable for removing parts from the input string (set newValue to null), optimized for this;
• Same as original .NET C# string.Replace behavior, same exceptions;
• Well commented, easy to understand;
• Simpler – no regular expressions. Regular expressions are always slower because of their versatility (even compiled);
• This method is well tested and there are no hidden flaws like infinite loop in other's solutions, even highly rated:

@AsValeO: Not works with Regex language elements, so it's not universal method

@Mike Stillion: There is a problem with this code. If the text in new is a superset of the text in old, this can produce an endless loop.

Benchmark-proof: this solution is 2.59X times faster than regex from @Steve B., code:

// Results:
// 1/2. Regular expression solution: 4486 milliseconds
// 2/2. Current solution: 1727 milliseconds — 2.59X times FASTER! than regex!

// Notes: the test was started 5 times, the result is an average; release build.

const int benchmarkIterations = 1000000;

const string newValue = "Fod";
long totalLenght = 0;

Stopwatch regexStopwatch = Stopwatch.StartNew();
string tempString1;
for (int i = 0; i < benchmarkIterations; i++)

Original idea – @Darky711; thanks @MinerR for StringBuilder.

If you don't have the UITextView handy (for example, you're sizing table view cells), you'll have to calculate the size by measuring the string, then accounting for the 8 pt of padding on each side of a UITextView. For example, if you know the desired width of your text view and want to figure out the corresponding height:

NSString * string = ...;
CGFloat textViewWidth = ...;
UIFont * font = ...;

CGSize size = CGSizeMake(textViewWidth - 8 - 8, 100000);
size.height = [string sizeWithFont:font constrainedToSize:size].height + 8 + 8;

Here, each 8 is accounting for one of the four padded edges, and 100000 just serves as a very large maximum size.

In practice, you may want to add an extra font.leading to the height; this adds a blank line below your text, which may look better if there are visually heavy controls directly beneath the text view.

This is my working solution:

select tabname as table_name
from syscat.tables
where tabschema = 'schema_name' -- put schema name here
      and type = 'T'
order by tabname

If you install the Travis CI Client you can use travis restart <job#> to manually re-run a build from the console. You can find the last job# for a branch using travis show <branch>

travis show master
travis restart 48 #use Job number without .1
travis logs master

UPDATE: Sadly it looks like this doesn't start a new build using the latest commit, but instead just restarts a previous build using the previous state of the repo.

I wrote my own index-of function, inspired by strpos() in PHP.

<xsl:function name="fn:strpos">
    <xsl:param name="haystack"/>
    <xsl:param name="needle"/>
    <xsl:value-of select="fn:_strpos($haystack, $needle, 1, string-length($haystack) - string-length($needle))"/>
</xsl:function>

<xsl:function name="fn:_strpos">
    <xsl:param name="haystack"/>
    <xsl:param name="needle"/>
    <xsl:param name="pos"/>
    <xsl:param name="count"/>
    <xsl:choose>
        <xsl:when test="$count &lt; 0">
            <!-- Not found. Most common is to return -1 here (or maybe 0 in XSL?). -->
            <!-- But this way, the result can be used with substring() without checking. -->
            <xsl:value-of select="string-length($haystack) + 1"/>
        </xsl:when>
        <xsl:when test="starts-with(substring($haystack, $pos), $needle)">
            <xsl:value-of select="$pos"/>
        </xsl:when>
        <xsl:otherwise>
            <xsl:value-of select="fn:_strpos($haystack, $needle, $pos + 1, $count - 1)"/>
        </xsl:otherwise>
    </xsl:choose>
</xsl:function>

Try print(e.message) this should be able to print your exception.

try:
    connection = manager.connect("I2Cx")
except Exception, e:
    print(e.message)

in my case I have used - (Hyphen) in my script name in case of Jenkinsfile Library. Got resolved after replacing Hyphen(-) with Underscore(_)

Interestingly, I kept getting that error. What fixed it for me was creating a config called gacutil.exe.config in the same directory as gacutil.exe. The config content (a text file) were:

<?xml version ="1.0"?> <configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <requiredRuntime safemode="true" imageVersion="v4.0.30319" version="v4.0.30319"/>
    </startup> </configuration>

I'm posting this here for reference and ask if anyone knows what's actually happening under the hood. I'm not claiming this is the "proper" way of doing it

Add:

#ifdef _WIN32
if (AttachConsole(ATTACH_PARENT_PROCESS)) {
    freopen("CONOUT$", "w", stdout);
    freopen("CONOUT$", "w", stderr);
}
#endif

at the top of main(). This will enable output to the console only if the program is started in a console, and won't pop up a console window in other situations. If you want to create a console window to display messages when you run the app outside a console you can change the condition to:

if (AttachConsole(ATTACH_PARENT_PROCESS) || AllocConsole())

As @DSM points out, you can do this more directly using the vectorised string methods:

df['Date'].str[-4:].astype(int)

Or using extract (assuming there is only one set of digits of length 4 somewhere in each string):

df['Date'].str.extract('(?P<year>\d{4})').astype(int)

An alternative slightly more flexible way, might be to use apply (or equivalently map) to do this:

df['Date'] = df['Date'].apply(lambda x: int(str(x)[-4:]))
             #  converts the last 4 characters of the string to an integer

The lambda function, is taking the input from the Date and converting it to a year.
You could (and perhaps should) write this more verbosely as:

def convert_to_year(date_in_some_format):
    date_as_string = str(date_in_some_format)  # cast to string
    year_as_string = date_in_some_format[-4:] # last four characters
    return int(year_as_string)

df['Date'] = df['Date'].apply(convert_to_year)

Perhaps 'Year' is a better name for this column...

Just my two cents:

git ls-files | grep -x relative/path

where relative/path can be easily determined by pressing tab within an auto-completion shell. Add an additional | wc -l to get a 1 or 0 output.

Assuming you want to use a regex and you want/need Unicode-cognisant 2.x code that is 2to3-ready:

>>> import re
>>> rx = re.compile(u'[\W_]+', re.UNICODE)
>>> data = u''.join(unichr(i) for i in range(256))
>>> rx.sub(u'', data)
u'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\xaa\xb2 [snip] \xfe\xff'
>>>

The distance estimate provided by iOS is based on the ratio of the beacon signal strength (rssi) over the calibrated transmitter power (txPower). The txPower is the known measured signal strength in rssi at 1 meter away. Each beacon must be calibrated with this txPower value to allow accurate distance estimates.

While the distance estimates are useful, they are not perfect, and require that you control for other variables. Be sure you read up on the complexities and limitations before misusing this.

When we were building the Android iBeacon library, we had to come up with our own independent algorithm because the iOS CoreLocation source code is not available. We measured a bunch of rssi measurements at known distances, then did a best fit curve to match our data points. The algorithm we came up with is shown below as Java code.

Note that the term "accuracy" here is iOS speak for distance in meters. This formula isn't perfect, but it roughly approximates what iOS does.

protected static double calculateAccuracy(int txPower, double rssi) {
  if (rssi == 0) {
    return -1.0; // if we cannot determine accuracy, return -1.
  }

  double ratio = rssi*1.0/txPower;
  if (ratio < 1.0) {
    return Math.pow(ratio,10);
  }
  else {
    double accuracy =  (0.89976)*Math.pow(ratio,7.7095) + 0.111;    
    return accuracy;
  }
}   

Note: The values 0.89976, 7.7095 and 0.111 are the three constants calculated when solving for a best fit curve to our measured data points. YMMV

The links in Dave's post are great. Just to put a few technical details about the google links into an answer here on SO:

Google Calendar Link

<a href="http://www.google.com/calendar/event?action=TEMPLATE&text=Example%20Event&dates=20131124T010000Z/20131124T020000Z&details=Event%20Details%20Here&location=123%20Main%20St%2C%20Example%2C%20NY">Add to gCal</a>

the parameters being:

• action=TEMPLATE (required)
• text (url encoded name of the event)
• dates (ISO date format, startdate/enddate - must have both start and end time - the button generator will let you leave the endtime blank, but you must have one or it won't work.)
  • to use the user's timezone: 20131208T160000/20131208T180000
  • to use global time, convert to UTC, then use 20131208T160000Z/20131208T180000Z
  • all day events, you can use 20131208/20131209 - note that the button generator gets it wrong. You must use the following date as the end date for a one day all day event, or +1 day to whatever you want the end date to be.
• details (url encoded event description/details)
• location (url encoded location of the event - make sure it's an address google maps can read easily)

Update Feb 2018:

Here's a new link structure that seems to support the new google version of google calendar w/o requiring API interaction:

https://calendar.google.com/calendar/r/eventedit?text=My+Custom+Event&dates=20180512T230000Z/20180513T030000Z&details=For+details,+link+here:+https://example.com/tickets-43251101208&location=Garage+Boston+-+20+Linden+Street+-+Allston,+MA+02134

New base url: https://calendar.google.com/calendar/r/eventedit

New parameters:

• text (name of the event)
• dates (ISO date format, startdate/enddate - must have both start and end time)
  • an event w/ start/end times: 20131208T160000/20131208T180000
  • all day events, you can use 20131208/20131209 - end date must be +1 day to whatever you want the end date to be.
• ctz (timezone such as America/New_York - leave blank to use the user's default timezone. Highly recommended to include this in almost all situations. For example, a reminder for a video conference: if three people in different timezones clicked this link and set a reminder for their "own" Tuesday at 10:00am, this would not work out well.)
• details (url encoded event description/details)
• location (url encoded location of the event - make sure it's an address google maps can read easily)
• add (comma separated list of emails - adds guests to your new event)

Notes:

• the old url structure above now redirects here
• supports https
• deals w/ timezones better
• accepts + for space in addition to %20 (urlencode vs rawurlencode in php - both work)

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

More discussion on worksheet code names can be found here.

    BaseClass.call(this);
    // add your stuff
    var morePrivates;
    this.isNotPrivate = 'I know';
}
var o = MiddleClass.prototype = Object.create(BaseClass.prototype);
MiddleClass.prototype.constructor = MiddleClass;
// add your prototype stuff
o.stuff_is_never_private = 'whatever_except_getter_and_setter';



// TopClass extends MiddleClass
function TopClass(toBePrivate){
    MiddleClass.call(this);
    // add your stuff
    var morePrivates;
    this.isNotPrivate = 'I know';
}
var o = TopClass.prototype = Object.create(MiddleClass.prototype);
TopClass.prototype.constructor = TopClass;
// add your prototype stuff
o.stuff_is_never_private = 'whatever_except_getter_and_setter';


// to be continued...

Create "instance" with getter and setter:

function doNotExtendMe(toBePrivate){
    var morePrivates;
    return {
        // add getters, setters and any stuff you want
    }
}

If this code is in your .htaccess file (without the check for mod_rewrite.c)

DirectoryIndex index.php
RewriteEngine on

RewriteCond $1 !^(index\.php|assets|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php/$1 [L,QSA]

and you can visit any page on your site with getting a 500 server error I think it's safe to say mod rewrite is switched on.

You can delete the service:

sc delete ServiceName

Then recreate the service.

    return text.match(regex);

words_in_text('Düsseldorf, Köln, ??????, ???, ??????? !@#$');

// returns array ["Düsseldorf", "Köln", "??????", "???", "???????"]

This regex will match all words in the text of any language...

$small = substr($big, 0, 100);

For String Manipulation here is a page with a lot of function that might help you in your future work.

Do you merely want to print the string that way, or do you want that to be the internal representation of the string? If the latter, create it as a raw string by prefixing it with r: r"Hello\tWorld\nHello World".

>>> a = r"Hello\tWorld\nHello World"
>>> a # in the interpreter, this calls repr()
'Hello\\tWorld\\nHello World'
>>> print a
Hello\tWorld\nHello World

Also, \s is not an escape character, except in regular expressions, and then it still has a much different meaning than what you're using it for.

To do this easily, the use of Stack is better. Create a Stack Then inside Stack add Align or Positioned and set position according to your needed, You can add multiple Container.

Container
  child: Stack(
    children: <Widget>[
      Align(
         alignment: FractionalOffset.center,
         child: Text(
            "? 1000",
         )
      ),
      Positioned(
        bottom: 0,
        child: Container(
           width: double.infinity,
           height: 30,
           child: Text(
             "Balance", ,
           )
         ),
       )
    ],
  )
)

Stack a widget that positions its children relative to the edges of its box.

Stack class is useful if you want to overlap several children in a simple way, for example having some text and an image, overlaid with a gradient and a button attached to the bottom.

With next variant I have no reaction:

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); //before     
dialog.setContentView(R.layout.logindialog);

So, I try to use next:

dialog.supportRequestWindowFeature(Window.FEATURE_NO_TITLE); //before     
dialog.setContentView(R.layout.logindialog);

This variant work excellent.

I would do something like this but i bet there is a simpler way. i think the sql from linqtosql would use a select from person Where NOT EXIST(select from your exclusion list)

static class Program
{
    public class Person
    {
        public string Key { get; set; }
        public Person(string key)
        {
           Key = key;
        }
    }
    public class NotPerson
    {
        public string Key { get; set; }
        public NotPerson(string key)
        {
           Key = key;
        }
    }
    static void Main()
    {

       List<Person> persons = new List<Person>()
       { 
           new Person ("1"),
           new Person ("2"),
           new Person ("3"),
           new Person ("4")
       };

       List<NotPerson> notpersons = new List<NotPerson>()
       { 
           new NotPerson ("3"),
           new NotPerson ("4")
       };

       var filteredResults = from n in persons
                             where !notpersons.Any(y => n.Key == y.Key)
                             select n;

       foreach (var item in filteredResults)
       {
          Console.WriteLine(item.Key);
       }
    }
 }

You can use in-place operator new. This would be a bit horrible, and I'd recommend keeping in a factory.

Car* createCars(unsigned number)
{
    if (number == 0 )
        return 0;
    Car* cars = reinterpret_cast<Car*>(new char[sizeof(Car)* number]);
    for(unsigned carId = 0;
        carId != number;
        ++carId)
    {
        new(cars+carId) Car(carId);
    }
    return cars;
}

And define a corresponding destroy so as to match the new used in this.

Whilst you certainly can use MySQL's IF() control flow function as demonstrated by dbemerlin's answer, I suspect it might be a little clearer to the reader (i.e. yourself, and any future developers who might pick up your code in the future) to use a CASE expression instead:

UPDATE Table
SET    A = CASE
         WHEN A > 0 AND A < 1 THEN 1
         WHEN A > 1 AND A < 2 THEN 2
         ELSE A
       END
WHERE  A IS NOT NULL

Of course, in this specific example it's a little wasteful to set A to itself in the ELSE clause—better entirely to filter such conditions from the UPDATE, via the WHERE clause:

UPDATE Table
SET    A = CASE
         WHEN A > 0 AND A < 1 THEN 1
         WHEN A > 1 AND A < 2 THEN 2
       END
WHERE  (A > 0 AND A < 1) OR (A > 1 AND A < 2)

(The inequalities entail A IS NOT NULL).

Or, if you want the intervals to be closed rather than open (note that this would set values of 0 to 1—if that is undesirable, one could explicitly filter such cases in the WHERE clause, or else add a higher precedence WHEN condition):

UPDATE Table
SET    A = CASE
         WHEN A BETWEEN 0 AND 1 THEN 1
         WHEN A BETWEEN 1 AND 2 THEN 2
       END
WHERE  A BETWEEN 0 AND 2

Though, as dbmerlin also pointed out, for this specific situation you could consider using CEIL() instead:

UPDATE Table SET A = CEIL(A) WHERE A BETWEEN 0 AND 2

HTML5 download attribute

Just to allow user to download the image or other file you may use the HTML5 download attribute.

Static file download

<a href="/images/image-name.jpg" download>
<!-- OR -->
<a href="/images/image-name.jpg" download="new-image-name.jpg"> 

Dynamic file download

In cases requesting image dynamically it is possible to emulate such download.

If your image is already loaded and you have the base64 source then:

function saveBase64AsFile(base64, fileName) {
    var link = document.createElement("a");

    document.body.appendChild(link); // for Firefox

    link.setAttribute("href", base64);
    link.setAttribute("download", fileName);
    link.click();
}

Otherwise if image file is downloaded as Blob you can use FileReader to convert it to Base64:

function saveBlobAsFile(blob, fileName) {
    var reader = new FileReader();

    reader.onloadend = function () {    
        var base64 = reader.result ;
        var link = document.createElement("a");

        document.body.appendChild(link); // for Firefox

        link.setAttribute("href", base64);
        link.setAttribute("download", fileName);
        link.click();
    };

    reader.readAsDataURL(blob);
}

Firefox

The anchor tag you are creating also needs to be added to the DOM in Firefox, in order to be recognized for click events (Link).

IE is not supported: Caniuse link

To get the shape as a list of ints, do tensor.get_shape().as_list().

To complete your tf.shape() call, try tensor2 = tf.reshape(tensor, tf.TensorShape([num_rows*num_cols, 1])). Or you can directly do tensor2 = tf.reshape(tensor, tf.TensorShape([-1, 1])) where its first dimension can be inferred.

With Pillow, you can also draw on an image using the ImageDraw module. You can draw lines, points, ellipses, rectangles, arcs, bitmaps, chords, pieslices, polygons, shapes and text.

from PIL import Image, ImageDraw
blank_image = Image.new('RGBA', (400, 300), 'white')
img_draw = ImageDraw.Draw(blank_image)
img_draw.rectangle((70, 50, 270, 200), outline='red', fill='blue')
img_draw.text((70, 250), 'Hello World', fill='green')
blank_image.save('drawn_image.jpg')

we create an Image object with the new() method. This returns an Image object with no loaded image. We then add a rectangle and some text to the image before saving it.

It is a shorthand for Nullable<int>. Nullable<T> is used to allow a value type to be set to null. Value types usually cannot be null.

To add to the above: If interrupt is not working, you can restart the kernel.

Go to the kernel dropdown >> restart >> restart and clear output. This usually does the trick. If this still doesn't work, kill the kernel in the terminal (or task manager) and then restart.

Interrupt doesn't work well for all processes. I especially have this problem using the R kernel.

Separate the business rules for age from the actions e.g. (NB just typed, not checked)

enum eAgerange { eChild, eYouth, eAdult, eAncient};
eAgeRange ar;
if(age <= 8) ar = eChild;
else if(age <= 15) ar = eYouth;
else if(age <= 100) ar = eAdult;
else ar = eAncient;
switch(ar)
{
 case eChild: 
     // action
 case eYouth:
     // action
 case eAdult:
     // action
 case eAncient:
     // action
 default: throw new NotImplementedException($"Oops {ar.ToString()} not handled");
}

For PHPStorm 2020.3.2 on ubuntu inorder to reset expiration license, you should run following commands:

sudo rm ~/.config/JetBrains/PhpStorm2020.3/options/other.xml 
sudo rm ~/.config/JetBrains/PhpStorm2020.3/eval/*          
sudo rm -rf .java/.userPrefs

DOM stands for Document Object Model. It is the W3C(World Wide Web Consortium) Standard. It define standard for accessing and manipulating HTML and XML document and The elements of DOM is head,title,body tag etc. So the answer of your first statement is

Statement #1 You can add multiple classes to a single DOM element.

Explanation : "div class="cssclass1 cssclass2 cssclass3"

Here tag is element of DOM and i have applied multiple classes to DOM element.

request.referer is set by Rack and is set as follows:

def referer
  @env['HTTP_REFERER'] || '/'
end

Just do a redirect_to request.referer and it will always redirect to the true referring page, or the root_path ('/'). This is essential when passing tests that fail in cases of direct-nav to a particular page in which the controller throws a redirect_to :back

Most Secure Solution, JS only

As mentioned by alko989, there is a major security flaw with _blank (details here).

To avoid it from pure JS code:

const openInNewTab = (url) => {
  const newWindow = window.open(url, '_blank', 'noopener,noreferrer')
  if (newWindow) newWindow.opener = null
}

Then add to your onClick

onClick={() => openInNewTab('https://stackoverflow.com')}

The third param can also take these optional values, based on your needs.

This is just a suggestion that follows Dax's answer. (I would put it in a comment at that answer, but I don't have enough reputation yet to comment on others questions).

Id's should be unique for every field, so, if you have multiple date fields in your form (or forms), you could use the class element instead of the ID:

 $(function() { $( ".datepicker" ).datepicker({ dateFormat: 'yy-mm-dd' }); });

and your input as:

 <input type="text" class="datepicker" name="your-name" />

Now, every time you need the date picker, just add that class. PS I know, you still have to use the js :(, but at least you're set for all your site. My 2 cents...

M2_HOME (and the like) is not to be used as of Maven 3.5.0. See MNG-5607 and Release Notes for details.

Below is an other approach that was useful for me

convertLittleEndianByteArrayToBigEndianByteArray (byte littlendianByte[], byte bigEndianByte[], int ArraySize){
    int i =0;

    for(i =0;i<ArraySize;i++){
      bigEndianByte[i] = (littlendianByte[ArraySize-i-1] << 7 & 0x80) | (littlendianByte[ArraySize-i-1] << 5 & 0x40) |
                            (littlendianByte[ArraySize-i-1] << 3 & 0x20) | (littlendianByte[ArraySize-i-1] << 1 & 0x10) |
                            (littlendianByte[ArraySize-i-1] >>1 & 0x08) | (littlendianByte[ArraySize-i-1] >> 3 & 0x04) |
                            (littlendianByte[ArraySize-i-1] >>5 & 0x02) | (littlendianByte[ArraySize-i-1] >> 7 & 0x01) ;
    }
}

Create-react-app Version 2+ answer

For recent (> v2) versions of create-react-app (and possible older as well), add the following line to your package.json, then rebuild.

"homepage": "./"

You should now see the build/index.html will have relative links ./static/... instead of links to the server root: /static/....

If someone comes looking for configuring log4j2 programmatically in Java, then this link could help: (https://www.studytonight.com/post/log4j2-programmatic-configuration-in-java-class)

Here is the basic code for configuring a Console Appender:

ConfigurationBuilder<BuiltConfiguration> builder = ConfigurationBuilderFactory.newConfigurationBuilder();

builder.setStatusLevel(Level.DEBUG);
// naming the logger configuration
builder.setConfigurationName("DefaultLogger");

// create a console appender
AppenderComponentBuilder appenderBuilder = builder.newAppender("Console", "CONSOLE")
                .addAttribute("target", ConsoleAppender.Target.SYSTEM_OUT);
// add a layout like pattern, json etc
appenderBuilder.add(builder.newLayout("PatternLayout")
                .addAttribute("pattern", "%d %p %c [%t] %m%n"));
RootLoggerComponentBuilder rootLogger = builder.newRootLogger(Level.DEBUG);
rootLogger.add(builder.newAppenderRef("Console"));

builder.add(appenderBuilder);
builder.add(rootLogger);
Configurator.reconfigure(builder.build());

This will reconfigure the default rootLogger and will also create a new appender.

After reading all the answers and comments on this question, I thought to do a small experiment.

I generated 50,000 random booleans and called sum and count on them.

Here are my results:

>>> a = [bool(random.getrandbits(1)) for x in range(50000)]
>>> len(a)
50000
>>> a.count(False)
24884
>>> a.count(True)
25116
>>> def count_it(a):
...   curr = time.time()
...   counting = a.count(True)
...   print("Count it = " + str(time.time() - curr))
...   return counting
... 
>>> def sum_it(a):
...   curr = time.time()
...   counting = sum(a)
...   print("Sum it = " + str(time.time() - curr))
...   return counting
... 
>>> count_it(a)
Count it = 0.00121307373046875
25015
>>> sum_it(a)
Sum it = 0.004102230072021484
25015

Just to be sure, I repeated it several more times:

>>> count_it(a)
Count it = 0.0013530254364013672
25015
>>> count_it(a)
Count it = 0.0014507770538330078
25015
>>> count_it(a)
Count it = 0.0013344287872314453
25015
>>> sum_it(a)
Sum it = 0.003480195999145508
25015
>>> sum_it(a)
Sum it = 0.0035257339477539062
25015
>>> sum_it(a)
Sum it = 0.003350496292114258
25015
>>> sum_it(a)
Sum it = 0.003744363784790039
25015

And as you can see, count is 3 times faster than sum. So I would suggest to use count as I did in count_it.

Python version: 3.6.7

I would dump your query so you can take a look at the SQL that was actually executed and see how that differs from what you wrote.

You should be able to do that with the following code:

$queries = DB::getQueryLog();
$last_query = end($queries);
var_dump($last_query);
die();

Hopefully that should give you enough information to allow you to figure out what's gone wrong.

As the more recent MySQL documentation on view restrictions says:

Before MySQL 5.7.7, subqueries cannot be used in the FROM clause of a view.

This means, that choosing a MySQL v5.7.7 or newer or upgrading the existing MySQL instance to such a version, would remove this restriction on views completely.

However, if you have a current production MySQL version that is earlier than v5.7.7, then the removal of this restriction on views should only be one of the criteria being assessed while making a decision as to upgrade or not. Using the workaround techniques described in the other answers may be a more viable solution - at least on the shorter run.

You could try this

=IF(ISNA(VLOOKUP(<single column I value>,<entire column E range>,1,FALSE)),FALSE, TRUE)

-or-

=IF(ISNA(VLOOKUP(<single column I value>,<entire column E range>,1,FALSE)),"FALSE", "File found in row "   & MATCH(<single column I value>,<entire column E range>,0))

you could replace <single column I value> and <entire column E range> with named ranged. That'd probably be the easiest.

Just drag that formula all the way down the length of your I column in whatever column you want.

Here you can check palindrome a number of String dynamically

import java.util.Scanner;

public class Checkpalindrome {
 public static void main(String args[]) {
  String original, reverse = "";
  Scanner in = new Scanner(System.in);
  System.out.println("Enter How Many number of Input you want : ");
  int numOfInt = in.nextInt();
  original = in.nextLine();
do {
  if (numOfInt == 0) {
    System.out.println("Your Input Conplete");
   } 
  else {
    System.out.println("Enter a string to check palindrome");
    original = in.nextLine();

    StringBuffer buffer = new StringBuffer(original);
    reverse = buffer.reverse().toString();

  if (original.equalsIgnoreCase(reverse)) {
    System.out.println("The entered string is Palindrome:"+reverse);
   } 
  else {
    System.out.println("The entered string is not Palindrome:"+reverse);
    }
 }
   numOfInt--;
    } while (numOfInt >= 0);
}
}

When you don't want the user to see the comment use:

<%-- comment --%>

If you don't care / want the user to be able to view source and see the comment you can use:

<!-- comment -->

When in doubt use the JSP comment.

you can use solutions without adding "Access-Control-Allow-Origin": "*", if your server is already using Proxy gateway this issue will not happen because the front and backend will be route in the same IP and port in client side but for development, you need one of this three solution if you don't need extra code 1- simulate the real environment by using a proxy server and configure the front and backend in the same port

2- if you using Chrome you can use the extension called Allow-Control-Allow-Origin: * it will help you to avoid this problem

3- you can use the code but some browsers versions may not support that so try to use one of the previous solutions

the best solution is using a proxy like ngnix its easy to configure and it will simulate the real situation of the production deployment

For HTML5, html5 lib has been abandoned for years now. The only HTML5 library I can find with a recent update and maintenance records is html5-php which was just brought to beta 1.0 a little over a week ago.

        foreach (string key in browser.Capabilities.Keys)
        {
            Literal1.Text += "<tr><td>" + key + "</td><td>" + browser[key] + "</tr>";

    myObj['Base'] = [];
    myObj['Base']['Base.panel.panel_base'] = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',  AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };

    console.log(myObj);

    if ('Base' in myObj) {
      console.log('Base found');

      if ('Base.panel.panel_base' in myObj['Base'])  {
        console.log('Base.panel.panel_base found'); 


      console.log('old value: ' + myObj['Base']['Base.panel.panel_base'].Context);  
      myObj['Base']['Base.panel.panel_base'] = 'new Value';
      console.log('new value: ' + myObj['Base']['Base.panel.panel_base']);
      }
    }

Output:

• Base found
• Base.panel.panel_base found
• old value: Base
• new value: new Value

The array operation works. There is no problem.

Iteration:

     Object.keys(myObj['Base']).forEach(function(key, index) {            
        var value = objcons['Base'][key];                   
      }, myObj);

I encountered a similar problem in my project. After struggling a lot, I found this solution:

if ($.datepicker.parseDate("dd/mm/yy","17/06/2015") > $.datepicker.parseDate("dd/mm/yy","20/06/2015"))
    // do something

You DO NOT NEED plugins like jQuery Validate or Moment.js for this issue. Hope this solution helps.

You can sharpen an image using an unsharp mask. You can find more information about unsharp masking here. And here's a Python implementation using OpenCV:

import cv2 as cv
import numpy as np

def unsharp_mask(image, kernel_size=(5, 5), sigma=1.0, amount=1.0, threshold=0):
    """Return a sharpened version of the image, using an unsharp mask."""
    blurred = cv.GaussianBlur(image, kernel_size, sigma)
    sharpened = float(amount + 1) * image - float(amount) * blurred
    sharpened = np.maximum(sharpened, np.zeros(sharpened.shape))
    sharpened = np.minimum(sharpened, 255 * np.ones(sharpened.shape))
    sharpened = sharpened.round().astype(np.uint8)
    if threshold > 0:
        low_contrast_mask = np.absolute(image - blurred) < threshold
        np.copyto(sharpened, image, where=low_contrast_mask)
    return sharpened

def example():
    image = cv.imread('my-image.jpg')
    sharpened_image = unsharp_mask(image)
    cv.imwrite('my-sharpened-image.jpg', sharpened_image)

>> "1,2,3,4".split(",")
=> ["1", "2", "3", "4"]

Or for integers:

>> "1,2,3,4".split(",").map { |s| s.to_i }
=> [1, 2, 3, 4]

Or for later versions of ruby (>= 1.9 - as pointed out by Alex):

>> "1,2,3,4".split(",").map(&:to_i)
=> [1, 2, 3, 4]

User could change user agent . Try testing for webkit prefixed property in style object of body element

Use max-width on the images too. Change:

.erb-image-wrapper img{
    width:100% !important;
    height:100% !important;
    display:block;
}

to...

.erb-image-wrapper img{

It appears you're missing an important point here: JavaScript is a single-threaded execution environment. Let's look again at your code, note I've added alert("Here"):

var isPaused = false;

function firstFunction(){
    isPaused = true;
    for(i=0;i<x;i++){
        // do something
    }
    isPaused = false;
};

function secondFunction(){
    firstFunction()

    alert("Here");

    function waitForIt(){
        if (isPaused) {
            setTimeout(function(){waitForIt()},100);
        } else {
            // go do that thing
        };
    }
};

You don't have to wait for isPaused. When you see the "Here" alert, isPaused will be false already, and firstFunction will have returned. That's because you cannot "yield" from inside the for loop (// do something), the loop may not be interrupted and will have to fully complete first (more details: Javascript thread-handling and race-conditions).

That said, you still can make the code flow inside firstFunction to be asynchronous and use either callback or promise to notify the caller. You'd have to give up upon for loop and simulate it with if instead (JSFiddle):

function firstFunction()
{
    var deferred = $.Deferred();

    var i = 0;
    var nextStep = function() {
        if (i<10) {
            // Do something
            printOutput("Step: " + i);
            i++;
            setTimeout(nextStep, 500); 
        }
        else {
            deferred.resolve(i);
        }
    }
    nextStep();
    return deferred.promise();
}

function secondFunction()
{
    var promise = firstFunction();
    promise.then(function(result) { 
        printOutput("Result: " + result);
    });
}

On a side note, JavaScript 1.7 has introduced yield keyword as a part of generators. That will allow to "punch" asynchronous holes in otherwise synchronous JavaScript code flow (more details and an example). However, the browser support for generators is currently limited to Firefox and Chrome, AFAIK.

I too wanted to do something similar, this is what I found: (SDK 3.1.3)

I have a view controller A (itself owned by a Nav controller) which loads VC B on a button press:

In AViewController.m

BViewController *bController = [[BViewController alloc] initWithNibName:@"Bnib" bundle:nil];
[self.navigationController pushViewController:bController animated:YES];
[bController release];

Now VC B has its interface from Bnib, but when a button is pressed, I want to go to an 'edit mode' which has a separate UI from a different nib, but I don't want a new VC for the edit mode, I want the new nib to be associated with my existing B VC.

So, in BViewController.m (in button press method)

NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"EditMode" owner:self options:nil];
UIView *theEditView = [nibObjects objectAtIndex:0];
self.editView = theEditView;
[self.view addSubview:theEditView];

Then on another button press (to exit edit mode):

[editView removeFromSuperview];

and I'm back to my original Bnib.

This works fine, but note my EditMode.nib has only 1 top level obj in it, a UIView obj. It doesn't matter whether the File's Owner in this nib is set as BViewController or the default NSObject, BUT make sure the View Outlet in the File's Owner is NOT set to anything. If it is, then I get a exc_bad_access crash and xcode proceeds to load 6677 stack frames showing an internal UIView method repeatedly called... so looks like an infinite loop. (The View Outlet IS set in my original Bnib however)

Hope this helps.

You should try

if (row.Table.Columns.Contains("US_OTHERFRIEND"))

I don't believe that row has a columns property itself.

Arrays have a property .length that returns the number of elements.

var st =
    {
        "itema":{},
        "itemb":
        [
            {"id":"s01","cd":"c01","dd":"d01"},
            {"id":"s02","cd":"c02","dd":"d02"}
        ]
    };

st.itemb.length // 2

Do you use some AJAX framework? Using jQuery it would be:

$.getScript('script.js');

If you're not using any framework then see the answer by Harmen.

(Maybe it is not worth to use jQuery just to do this one simple thing (or maybe it is) but if you already have it loaded then you might as well use it. I have seen websites that have jQuery loaded e.g. with Bootstrap but still use the DOM API directly in a way that is not always portable, instead of using the already loaded jQuery for that, and many people are not aware of the fact that even getElementById() doesn't work consistently on all browsers - see this answer for details.)

UPDATE:

It's been years since I wrote this answer and I think it's worth pointing out here that today you can use:

• SystemJS
• ModuleLoader
• jspm.io

to dynamically load scripts. Those may be relevant to people reading this question.

In Windows 7, if you have just created it manually with Windows Explorer, the directory structure is similar to this one:

C:
  \AAA
    \BBB
      \CCC
        \DDD

And running the code suggested in the original question to clean the directory C:\AAA, the line di.Delete(true) always fails with IOException "The directory is not empty" when trying to delete BBB. It is probably because of some kind of delays/caching in Windows Explorer.

The following code works reliably for me:

static void Main(string[] args)
{
    DirectoryInfo di = new DirectoryInfo(@"c:\aaa");
    CleanDirectory(di);
}

private static void CleanDirectory(DirectoryInfo di)
{
    if (di == null)
        return;

    foreach (FileSystemInfo fsEntry in di.GetFileSystemInfos())
    {
        CleanDirectory(fsEntry as DirectoryInfo);
        fsEntry.Delete();
    }
    WaitForDirectoryToBecomeEmpty(di);
}

private static void WaitForDirectoryToBecomeEmpty(DirectoryInfo di)
{
    for (int i = 0; i < 5; i++)
    {
        if (di.GetFileSystemInfos().Length == 0)
            return;
        Console.WriteLine(di.FullName + i);
        Thread.Sleep(50 * i);
    }
}

This is the best solution ever rather than hacking CSS.

Other than the options mentioned above, there are a couple of other Solutions.

1. Modifying the project file (.CsProj) file

MSBuild supports the EnvironmentName Property which can help to set the right environment variable as per the Environment you wish to Deploy. The environment name would be added in the web.config during the Publish phase.

Simply open the project file (*.csProj) and add the following XML.

<!-- Custom Property Group added to add the Environment name during publish
  The EnvironmentName property is used during the publish for the Environment variable in web.config
  -->
  <PropertyGroup Condition=" '$(Configuration)' == '' Or '$(Configuration)' == 'Debug'">
    <EnvironmentName>Development</EnvironmentName>
  </PropertyGroup>
  <PropertyGroup Condition=" '$(Configuration)' != '' AND '$(Configuration)' != 'Debug' ">
    <EnvironmentName>Production</EnvironmentName>
  </PropertyGroup>

Above code would add the environment name as Development for Debug configuration or if no configuration is specified. For any other Configuration the Environment name would be Production in the generated web.config file. More details here

2. Adding the EnvironmentName Property in the publish profiles.

We can add the <EnvironmentName> property in the publish profile as well. Open the publish profile file which is located at the Properties/PublishProfiles/{profilename.pubxml} This will set the Environment name in web.config when the project is published. More Details here

<PropertyGroup>
  <EnvironmentName>Development</EnvironmentName>
</PropertyGroup>

3. Command line options using dotnet publish

Additionaly, we can pass the property EnvironmentName as a command line option to the dotnet publish command. Following command would include the environment variable as Development in the web.config file.

dotnet publish -c Debug -r win-x64 /p:EnvironmentName=Development

1. Go to the site-packages directory where pip is installing your packages.
2. You should see the egg file that corresponds to the package you want to uninstall. Delete the egg file (or, to be on the safe side, move it to a different directory).
3. Do the same with the package files for the package you want to delete (in this case, the psycopg2 directory).
4. pip install YOUR-PACKAGE

If you want to save lines of code and leave the most flexible solution, we can deserialize the json string to a dynamic object:

p = lambda:None
p.__dict__ = json.loads('{"action": "print", "method": "onData", "data": "Madan Mohan"}')

>>>> p.action
output: u'print'

>>>> p.method
output: u'onData'

another version:

var yy = (new Date().getFullYear()+'').slice(-2);

If you have Xdebug installed you can override every setting by setting:

xdebug.force_display_errors = 1;
xdebug.force_error_reporting = -1;

force_display_errors

Type: int, Default value: 0, Introduced in Xdebug >= 2.3 If this setting is set to 1 then errors will always be displayed, no matter what the setting of PHP's display_errors is.

force_error_reporting

Type: int, Default value: 0, Introduced in Xdebug >= 2.3 This setting is a bitmask, like error_reporting. This bitmask will be logically ORed with the bitmask represented by error_reporting to dermine which errors should be displayed. This setting can only be made in php.ini and allows you to force certain errors from being shown no matter what an application does with ini_set().

you can try this along, it may help to give a shorter code on large function.

$('#menu li a').on('click', function(){
    $('li a.current').toggleClass('current');
});

And if you want to run a second function after the first one finishes, see this stackoverflow answer.

Another great free parser - http://bncscripts.com/free-php-rss-parser/ It's very light ( only 3kb ) and simple to use!

I had a similar problem where I didn't want to change the Python module search path and needed to load a module relatively from a script (in spite of "scripts can't import relative with all" as BrenBarn explained nicely above).

So I used the following hack. Unfortunately, it relies on the imp module that became deprecated since version 3.4 to be dropped in favour of importlib. (Is this possible with importlib, too? I don't know.) Still, the hack works for now.

Example for accessing members of moduleX in subpackage1 from a script residing in the subpackage2 folder:

#!/usr/bin/env python3

import inspect
import imp
import os

def get_script_dir(follow_symlinks=True):
    """
    Return directory of code defining this very function.
    Should work from a module as well as from a script.
    """
    script_path = inspect.getabsfile(get_script_dir)
    if follow_symlinks:
        script_path = os.path.realpath(script_path)
    return os.path.dirname(script_path)

# loading the module (hack, relying on deprecated imp-module)
PARENT_PATH = os.path.dirname(get_script_dir())
(x_file, x_path, x_desc) = imp.find_module('moduleX', [PARENT_PATH+'/'+'subpackage1'])
module_x = imp.load_module('subpackage1.moduleX', x_file, x_path, x_desc)

# importing a function and a value
function = module_x.my_function
VALUE = module_x.MY_CONST

A cleaner approach seems to be to modify the sys.path used for loading modules as mentioned by Federico.

#!/usr/bin/env python3

if __name__ == '__main__' and __package__ is None:
    from os import sys, path
    # __file__ should be defined in this case
    PARENT_DIR = path.dirname(path.dirname(path.abspath(__file__)))
   sys.path.append(PARENT_DIR)
from subpackage1.moduleX import *

On Windows you can use

netstat -na | find "your_port"

to narrow down the results. You can also filter for LISTENING, ESTABLISHED, TCP and such. Mind it's case-sensitive though.

for(std::map<std::string, std::map<std::string, std::string> >::iterator outer_iter=map.begin(); outer_iter!=map.end(); ++outer_iter) {
    for(std::map<std::string, std::string>::iterator inner_iter=outer_iter->second.begin(); inner_iter!=outer_iter->second.end(); ++inner_iter) {
        std::cout << inner_iter->second << std::endl;
    }
}

or nicer in C++0x:

for(auto outer_iter=map.begin(); outer_iter!=map.end(); ++outer_iter) {
    for(auto inner_iter=outer_iter->second.begin(); inner_iter!=outer_iter->second.end(); ++inner_iter) {
        std::cout << inner_iter->second << std::endl;
    }
}

One possibility, reducing the longer form before expanding all:

string.replaceAll("Milan Vasic", "Milan").replaceAll("Milan", "Milan Vasic")

Another way, treating Vasic as optional:

string.replaceAll("Milan( Vasic)?", "Milan Vasic")

Others have described solutions based on lookahead or alternation.

ToggleImageButton which implements Checkable interface and supports OnCheckedChangeListener and android:checked xml attribute:

public class ToggleImageButton extends ImageButton implements Checkable {
    private OnCheckedChangeListener onCheckedChangeListener;

some thing as follows ::

Add this After the body tag

This is a rough sketch, you will need to modify it according to your needs.

<script>
var f = document.createElement("form");
f.setAttribute('method',"post");
f.setAttribute('action',"submit.php");

var i = document.createElement("input"); //input element, text
i.setAttribute('type',"text");
i.setAttribute('name',"username");

var s = document.createElement("input"); //input element, Submit button
s.setAttribute('type',"submit");
s.setAttribute('value',"Submit");

f.appendChild(i);
f.appendChild(s);

//and some more input elements here
//and dont forget to add a submit button

document.getElementsByTagName('body')[0].appendChild(f);

</script>
