One way, as suggested in this post, is to mention version in pip as:

pip install -Iv MySQL_python==1.2.2

i.e. Use == and mention the version number to install only that version. -I, --ignore-installed ignores already installed packages.

This error is weird as many proposed answers and got mixed solutions. I tried them, add them. It was only when I added pip install --upgrade pip finally removed the error for me. But I have no time to isolate which is which,so this is just fyi.

You define the dependent module inside the setup.py of your own package with the "install_requires" option.

If your package needs to have some console script generated then you can use the "console_scripts" entry point in order to generate a wrapper script that will be placed within the 'bin' folder (e.g. of your virtualenv environment).

Support for TLS 1.0 and 1.1 was dropped for PyPI. If your system does not use a more recent version, it could explain your error.

Could you try reinstalling pip system-wide, to update your system dependencies to a newer version of TLS?

This seems to be related to Unable to install Python libraries

See Dominique Barton's answer:

Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.

On Debian-based systems I'd try:

apt-get update && apt-get upgrade python-pip

On Red Hat Linux-based systems:

yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)

On Mac:

sudo easy_install -U pip

You can also try to update openssl separately.

Note: Avoid using python setup.py install use pip install .

You need to remove all files manually, and also undo any other stuff that installation did manually.

If you don't know the list of all files, you can reinstall it with the --record option, and take a look at the list this produces.

To record a list of installed files, you can use:

python setup.py install --record files.txt

Once you want to uninstall you can use xargs to do the removal:

xargs rm -rf < files.txt

Or if you're running Windows, use Powershell:

Get-Content files.txt | ForEach-Object {Remove-Item $_ -Recurse -Force}

Then delete also the containing directory, e.g. /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/my_module-0.1.egg/ on macOS. It has no files, but Python will still import an empty module:

>>> import my_module
>>> my_module.__file__
None

Once deleted, Python shows:

>>> import my_module
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'my_module'

sudo apt-get install python-dev  # for python2.x installs
sudo apt-get install python3-dev  # for python3.x installs

It will install any missing headers. It solved my issue

setup.py is a Python file like any other. It can take any name, except by convention it is named setup.py so that there is not a different procedure with each script.

Most frequently setup.py is used to install a Python module but server other purposes:

Modules:

Perhaps this is most famous usage of setup.py is in modules. Although they can be installed using pip, old Python versions did not include pip by default and they needed to be installed separately.

If you wanted to install a module but did not want to install pip, just about the only alternative was to install the module from setup.py file. This could be achieved via python setup.py install. This would install the Python module to the root dictionary (without pip, easy_install ect).

This method is often used when pip will fail. For example if the correct Python version of the desired package is not available via pipperhaps because it is no longer maintained, , downloading the source and running python setup.py install would perform the same thing, except in the case of compiled binaries are required, (but will disregard the Python version -unless an error is returned).

Another use of setup.py is to install a package from source. If a module is still under development the wheel files will not be available and the only way to install is to install from the source directly.

Building Python extensions:

When a module has been built it can be converted into module ready for distribution using a distutils setup script. Once built these can be installed using the command above.

A setup script is easy to build and once the file has been properly configured and can be compiled by running python setup.py build (see link for all commands).

Once again it is named setup.py for ease of use and by convention, but can take any name.

Cython:

Another famous use of setup.py files include compiled extensions. These require a setup script with user defined values. They allow fast (but once compiled are platform dependant) execution. Here is a simple example from the documentation:

from distutils.core import setup
from Cython.Build import cythonize

setup(
    name = 'Hello world app',
    ext_modules = cythonize("hello.pyx"),
)

This can be compiled via python setup.py build

Cx_Freeze:

Another module requiring a setup script is cx_Freeze. This converts Python script to executables. This allows many commands such as descriptions, names, icons, packages to include, exclude ect and once run will produce a distributable application. An example from the documentation:

import sys
from cx_Freeze import setup, Executable
build_exe_options = {"packages": ["os"], "excludes": ["tkinter"]} 

base = None
if sys.platform == "win32":
    base = "Win32GUI"

setup(  name = "guifoo",
        version = "0.1",
        description = "My GUI application!",
        options = {"build_exe": build_exe_options},
        executables = [Executable("guifoo.py", base=base)])

This can be compiled via python setup.py build.

So what is a setup.py file?

Quite simply it is a script that builds or configures something in the Python environment.

A package when distributed should contain only one setup script but it is not uncommon to combine several together into a single setup script. Notice this often involves distutils but not always (as I showed in my last example). The thing to remember it just configures Python package/script in some way.

It takes the name so the same command can always be used when building or installing.

pip won't install binary packages and isn't well tested on Windows.

As Windows doesn't come with a compiler by default pip often can't be used there. easy_install can install binary packages for Windows.

Newer versions of pip have the ability to do what the OP wants via pip list -l or pip freeze -l (--list).
On Debian (at least) the man page doesn't make this clear, and I only discovered it - under the assumption that the feature must exist - with pip list --help.

There are recent comments that suggest this feature is not obvious in either the documentation or the existing answers (although hinted at by some), so I thought I should post. I would have preferred to do so as a comment, but I don't have the reputation points.

jQuery.load() is probably the easiest way to load data asynchronously using a selector, but you can also use any of the jquery ajax methods (get, post, getJSON, ajax, etc.)

Note that load allows you to use a selector to specify what piece of the loaded script you want to load, as in

$("#mydiv").load(location.href + " #mydiv");

Note that this technically does load the whole page and jquery removes everything but what you have selected, but that's all done internally.

This is now possible with C# 7.0's pattern matching. For example:

var myString = "abcDEF";

switch(myString)
{
    case string x when x.StartsWith("abc"):
        //Do something here
        break;
}

Use the logging module

def init_logging():
    rootLogger = logging.getLogger('my_logger')

    LOG_DIR = os.getcwd() + '/' + 'logs'
    if not os.path.exists(LOG_DIR):
        os.makedirs(LOG_DIR)
    fileHandler = logging.FileHandler("{0}/{1}.log".format(LOG_DIR, "g2"))
    rootLogger.addHandler(fileHandler)

    rootLogger.setLevel(logging.DEBUG)

    consoleHandler = logging.StreamHandler()
    rootLogger.addHandler(consoleHandler)

    return rootLogger

Get the logger:

logger = init_logging()

And start logging/output(ing):

logger.debug('Hi! :)')

If you want to do this from outside the script:

Python 2

from modulefinder import ModuleFinder
finder = ModuleFinder()
finder.run_script("myscript.py")
for name, mod in finder.modules.iteritems():
    print name

Python 3

from modulefinder import ModuleFinder
finder = ModuleFinder()
finder.run_script("myscript.py")
for name, mod in finder.modules.items():
    print(name)

This will print all modules loaded by myscript.py.

You can use unionByName to make this:

df = df_1.unionByName(df_2)

unionByName is available since Spark 2.3.0.

You do not need to calculate tree depths on the fly.

You can maintain them as you perform operations.

Furthermore, you don't actually in fact have to maintain track of depths; you can simply keep track of the difference between the left and right tree depths.

http://www.eternallyconfuzzled.com/tuts/datastructures/jsw_tut_avl.aspx

Just keeping track of the balance factor (difference between left and right subtrees) is I found easier from a programming POV, except that sorting out the balance factor after a rotation is a PITA...

In case someone wants to rename all the keys at once providing a list with the new names:

def rename_keys(dict_, new_keys):
    """
     new_keys: type List(), must match length of dict_
    """

    # dict_ = {oldK: value}
    # d1={oldK:newK,} maps old keys to the new ones:  
    d1 = dict( zip( list(dict_.keys()), new_keys) )

          # d1{oldK} == new_key 
    return {d1[oldK]: value for oldK, value in dict_.items()}

Using CliWrap:

var result = await Cli.Wrap("foobar.bat").ExecuteBufferedAsync();

var exitCode = result.ExitCode;
var stdOut = result.StandardOutput;

SELECT @var = col1,
       @var2 = col2
FROM   Table

Here is some interesting information about SET / SELECT

• SET is the ANSI standard for variable assignment, SELECT is not.
• SET can only assign one variable at a time, SELECT can make multiple assignments at once.
• If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
• When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value)
• As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.

if a device has an SD card, you use:

Environment.getExternalStorageState() 

if you don't have an SD card, you use:

Environment.getDataDirectory()

if there is no SD card, you can create your own directory on the device locally.

    //if there is no SD card, create new directory objects to make directory on device
        if (Environment.getExternalStorageState() == null) {
                        //create new file directory object
            directory = new File(Environment.getDataDirectory()
                    + "/RobotiumTestLog/");
            photoDirectory = new File(Environment.getDataDirectory()
                    + "/Robotium-Screenshots/");
            /*
             * this checks to see if there are any previous test photo files
             * if there are any photos, they are deleted for the sake of
             * memory
             */
            if (photoDirectory.exists()) {
                File[] dirFiles = photoDirectory.listFiles();
                if (dirFiles.length != 0) {
                    for (int ii = 0; ii <= dirFiles.length; ii++) {
                        dirFiles[ii].delete();
                    }
                }
            }
            // if no directory exists, create new directory
            if (!directory.exists()) {
                directory.mkdir();
            }

            // if phone DOES have sd card
        } else if (Environment.getExternalStorageState() != null) {
            // search for directory on SD card
            directory = new File(Environment.getExternalStorageDirectory()
                    + "/RobotiumTestLog/");
            photoDirectory = new File(
                    Environment.getExternalStorageDirectory()
                            + "/Robotium-Screenshots/");
            if (photoDirectory.exists()) {
                File[] dirFiles = photoDirectory.listFiles();
                if (dirFiles.length > 0) {
                    for (int ii = 0; ii < dirFiles.length; ii++) {
                        dirFiles[ii].delete();
                    }
                    dirFiles = null;
                }
            }
            // if no directory exists, create new directory to store test
            // results
            if (!directory.exists()) {
                directory.mkdir();
            }
        }// end of SD card checking

add permissions on your manifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Happy coding..

Your code "for /f "tokens=* delims=" %%x in (a.txt) do echo %%x" will work on most Windows Operating Systems unless you have modified commands.

So you could instead "cd" into the directory to read from before executing the "for /f" command to follow out the string. For instance if the file "a.txt" is located at C:\documents and settings\%USERNAME%\desktop\a.txt then you'd use the following.

cd "C:\documents and settings\%USERNAME%\desktop"
for /f "tokens=* delims=" %%x in (a.txt) do echo %%x
echo.
echo.
echo.
pause >nul
exit

But since this doesn't work on your computer for x reason there is an easier and more efficient way of doing this. Using the "type" command.

@echo off
color a
cls
cd "C:\documents and settings\%USERNAME%\desktop"
type a.txt
echo.
echo.
pause >nul
exit

Or if you'd like them to select the file from which to write in the batch you could do the following.

@echo off
:A
color a
cls
echo Choose the file that you want to read.
echo.
echo.
tree
echo.
echo.
echo.
set file=
set /p file=File:
cls
echo Reading from %file%
echo.
type %file%
echo.
echo.
echo.
set re=
set /p re=Y/N?:
if %re%==Y goto :A
if %re%==y goto :A
exit

To iterate on Avi Flax answer Object.keys(obj).length is correct for an object that doesnt have functions tied to it

example:

obj = {"lol": "what", owo: "pfft"};
Object.keys(obj).length; // should be 2

versus

arr = [];
obj = {"lol": "what", owo: "pfft"};
obj.omg = function(){
    _.each(obj, function(a){
        arr.push(a);
    });
};
Object.keys(obj).length; // should be 3 because it looks like this 
/* obj === {"lol": "what", owo: "pfft", omg: function(){_.each(obj, function(a){arr.push(a);});}} */

steps to avoid this:

1. do not put functions in an object that you want to count the number of keys in

2. use a seperate object or make a new object specifically for functions (if you want to count how many functions there are in the file using Object.keys(obj).length)

also yes i used the _ or underscore module from nodejs in my example

documentation can be found here http://underscorejs.org/ as well as its source on github and various other info

And finally a lodash implementation https://lodash.com/docs#size

_.size(obj)

Sorry, but there's to much coding going on here ...

I'll give the simplest one to you for free. I invented it back in 2005, although the javascript source now says it was their staff who came up with it - more than a year later!

Anyway, here it is, no javascript !!!

Just type in any URL you like, or a relative URL (to the pages location on server), it will always work.

Your code is correct. Kindly mark small correction.

     width: 750px;
     background-color: #777;
     display: block;
     **float: left;(wrong)**
     **float: right; (corrected)**
     border: 1px solid white;
}

Inline elements:

1. respect left & right margins and padding, but not top & bottom
2. cannot have a width and height set
3. allow other elements to sit to their left and right.
4. see very important side notes on this here.

Block elements:

1. respect all of those
2. force a line break after the block element
3. acquires full-width if width not defined

Inline-block elements:

1. allow other elements to sit to their left and right
2. respect top & bottom margins and padding
3. respect height and width

From W3Schools:

• An inline element has no line break before or after it, and it tolerates HTML elements next to it.

• A block element has some whitespace above and below it and does not tolerate any HTML elements next to it.

• An inline-block element is placed as an inline element (on the same line as adjacent content), but it behaves as a block element.

When you visualize this, it looks like this:

The image is taken from this page, which also talks some more about this subject.

If you want query parameters, you use @QueryParam.

public Todo getXML(@QueryParam("summary") String x, 
                   @QueryParam("description") String y)

But you won't be able to send a PUT from a plain web browser (today). If you type in the URL directly, it will be a GET.

Philosophically, this looks like it should be a POST, though. In REST, you typically either POST to a common resource, /todo, where that resource creates and returns a new resource, or you PUT to a specifically-identified resource, like /todo/<id>, for creation and/or update.

See my code which may help you. models.py

Try following

$.ajax({
    type: 'POST',
    url: 'Jqueryoperation.aspx?Operation=DeleteRow',
    contentType: 'application/json; charset=utf-8',
    data: { "Operation" : "DeleteRow", 
            "TwitterId" : 1 },
    dataType: 'json',
    cache: false,
    success: AjaxSucceeded,
    error: AjaxFailed
});

OR

$.ajax({
    type: 'POST',
    url: 'Jqueryoperation.aspx?Operation=DeleteRow&TwitterId=1',
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    cache: false,
    success: AjaxSucceeded,
    error: AjaxFailed
});

Use double quotes instead of single quotes in JSON object. I think this will solve the issue.

There's no real need to initialize to smallest/largest possible to find the smallest/largest in the array:

double largest = smallest = array[0];
for (int i=1; i<array_size; i++) {
    if (array[i] < smallest)
        smallest = array[i];
    if (array[i] > largest0
        largest= array[i];
}

Or, if you're doing it more than once:

#include <utility>

template <class iter>
std::pair<typename iter::value_type, typename iter::value_type> find_extrema(iter begin, iter end) {
    std::pair<typename iter::value_type, typename iter::value_type> ret;
    ret.first = ret.second = *begin;
    while (++begin != end) {
        if (*begin < ret.first)
           ret.first = *begin;
        if (*begin > ret.second)
           ret.second = *begin;
   }
   return ret;
}

The disadvantage of providing sample code -- I see others have already suggested the same idea.

Note that while the standard has a min_element and max_element, using these would require scanning through the data twice, which could be a problem if the array is large at all. Recent standards have addressed this by adding a std::minmax_element, which does the same as the find_extrema above (find both the minimum and maximum elements in a collection in a single pass).

Edit: Addressing the problem of finding the smallest non-zero value in an array of unsigned: observe that unsigned values "wrap around" when they reach an extreme. To find the smallest non-zero value, we can subtract one from each for the comparison. Any zero values will "wrap around" to the largest possible value for the type, but the relationship between other values will be retained. After we're done, we obviously add one back to the value we found.

unsigned int min_nonzero(std::vector<unsigned int> const &values) { 
    if (vector.size() == 0)
        return 0;
    unsigned int temp = values[0]-1;
    for (int i=1; i<values.size(); i++)
        if (values[i]-1 < temp)
            temp = values[i]-1;
    return temp+1;
}

Note this still uses the first element for the initial value, but we still don't need any "special case" code -- since that will wrap around to the largest possible value, any non-zero value will compare as being smaller. The result will be the smallest nonzero value, or 0 if and only if the vector contained no non-zero values.

Since you've already looked into strtok just continue down the same path and split your string using space (' ') as a delimiter, then use something as realloc to increase the size of the array containing the elements to be passed to execvp.

See the below example, but keep in mind that strtok will modify the string passed to it. If you don't want this to happen you are required to make a copy of the original string, using strcpy or similar function.

char    str[]= "ls -l";
char ** res  = NULL;
char *  p    = strtok (str, " ");
int n_spaces = 0, i;


/* split string and append tokens to 'res' */

while (p) {
  res = realloc (res, sizeof (char*) * ++n_spaces);

  if (res == NULL)
    exit (-1); /* memory allocation failed */

  res[n_spaces-1] = p;

  p = strtok (NULL, " ");
}

/* realloc one extra element for the last NULL */

res = realloc (res, sizeof (char*) * (n_spaces+1));
res[n_spaces] = 0;

/* print the result */

for (i = 0; i < (n_spaces+1); ++i)
  printf ("res[%d] = %s\n", i, res[i]);

/* free the memory allocated */

free (res);

res[0] = ls
res[1] = -l
res[2] = (null)

In regards to the octal misinterpretation of .js - I just used this...

parseInt(parseFloat(nv))

and after testing with leading zeros, came back everytime with the correct representation.

hope this helps.

I would have thought this would have been answered already - but surely what you want is this: box-shadow: 0 0 3px #CC0000;

Example: http://jsfiddle.net/vmzLW/

Input elements are inline by default. Add display:block to get the margins to apply. This will, however, break the buttons onto two separate lines. Use a wrapping <div> with text-align: center as suggested by others to get them on the same line.

This error would occur if any of the following variables were actually strings or null instead of arrays, in which case accessing them with an array syntax $var[$i] would be like trying to access a specific character in a string:

$catagory
$task
$fullText
$dueDate
$empId

In short, everything in your insert query.

Perhaps the $catagory variable is misspelled?

I tend to go for this pattern:

public class DogWithBreed
{
    public Dog Dog { get; set; }
    public string BreedName  { get; set; }
}

public IQueryable<DogWithBreed> GetDogsWithBreedNames()
{
    var db = new DogDataContext(ConnectString);
    var result = from d in db.Dogs
                 join b in db.Breeds on d.BreedId equals b.BreedId
                 select new DogWithBreed()
                        {
                            Dog = d,
                            BreedName = b.BreedName
                        };
    return result;
}

It means you have an extra class, but it's quick and easy to code, easily extensible, reusable and type-safe.

This is sort of an indirect answer, but this question got me thinking about the logic behind it, and I thought this might be worth sharing.

As everyone else has said, you use a do ... while loop when you want to execute the body at least once. But under what circumstances would you want to do that?

Well, the most obvious class of situations I can think of would be when the initial ("unprimed") value of the check condition is the same as when you want to exit. This means that you need to execute the loop body once to prime the condition to a non-exiting value, and then perform the actual repetition based on that condition. What with programmers being so lazy, someone decided to wrap this up in a control structure.

So for example, reading characters from a serial port with a timeout might take the form (in Python):

response_buffer = []
char_read = port.read(1)

while char_read:
    response_buffer.append(char_read)
    char_read = port.read(1)

# When there's nothing to read after 1s, there is no more data

response = ''.join(response_buffer)

Note the duplication of code: char_read = port.read(1). If Python had a do ... while loop, I might have used:

do:
    char_read = port.read(1)
    response_buffer.append(char_read)
while char_read

The added benefit for languages that create a new scope for loops: char_read does not pollute the function namespace. But note also that there is a better way to do this, and that is by using Python's None value:

response_buffer = []
char_read = None

while char_read != '':
    char_read = port.read(1)
    response_buffer.append(char_read)

response = ''.join(response_buffer)

So here's the crux of my point: in languages with nullable types, the situation initial_value == exit_value arises far less frequently, and that may be why you do not encounter it. I'm not saying it never happens, because there are still times when a function will return None to signify a valid condition. But in my hurried and briefly-considered opinion, this would happen a lot more if the languages you used did not allow for a value that signifies: this variable has not been initialised yet.

This is not perfect reasoning: in reality, now that null-values are common, they simply form one more element of the set of valid values a variable can take. But practically, programmers have a way to distinguish between a variable being in sensible state, which may include the loop exit state, and it being in an uninitialised state.

Please read this: http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx
You should set indicies for your html elements "name" attributes like planCompareViewModel[0].PlanId, planCompareViewModel[1].PlanId to make binder able to parse them into IEnumerable.
Instead of @foreach (var planVM in Model) use for loop and render names with indexes.

The compiler replaces null comparisons with a call to HasValue, so there is no real difference. Just do whichever is more readable/makes more sense to you and your colleagues.

Top Answer from Jon Adams

Here is how to implement this for the PowerShell folks

$IncommingPath = "F:\WebContent"
$Acl = Get-Acl $IncommingPath
$Ar = New-Object  system.security.accesscontrol.filesystemaccessrule("IIS AppPool\DefaultAppPool","FullControl","ContainerInherit, ObjectInherit", "None", "Allow")
$Acl.SetAccessRule($Ar)
Set-Acl $IncommingPath $Acl

Typing /** + then pressing Enter above a method signature will create Javadoc stubs for you.

As almost noted in comments to @BoltClock's answer, in modern browsers, you can actually add some html markup to pseudo-elements using the (url()) in combination with svg's <foreignObject> element.

You can either specify an URL pointing to an actual svg file, or create it with a dataURI version (data:image/svg+xml; charset=utf8, + encodeURIComponent(yourSvgMarkup))

But note that it is mostly a hack and that there are a lot of limitations :

• You can not load any external resources from this markup (no CSS, no images, no media etc.).
• You can not execute script.
• Since this won't be part of the DOM, the only way to alter it, is to pass the markup as a dataURI, and edit this dataURI in document.styleSheets. for this part, DOMParser and XMLSerializer may help.
• While the same operation allows us to load url-encoded media in <img> tags, this won't work in pseudo-elements (at least as of today, I don't know if it is specified anywhere that it shouldn't, so it may be a not-yet implemented feature).

Now, a small demo of some html markup in a pseudo element :

/* _x000D_
**  original svg code :_x000D_
*_x000D_
*<svg width="200" height="60"_x000D_
*     xmlns="http://www.w3.org/2000/svg">_x000D_

#log::after {_x000D_

As a workaround, you can use a code block to render the code literally. Just surround your text with triple backticks ```. It will look like this:

Note that using <pre> and <code> you get slightly different behaviour: &nbsp and <br /> will be parsed rather than inserted literally.

Use the join method from the Array type.

a.value = [a, b, c, d, e, f];
var stringValueYouWant = a.join();

The join method will return a string that is the concatenation of all the array elements. It will use the first parameter you pass as a separator - if you don't use one, it will use the default separator, which is the comma.

Open the file using Notepad++ and check the "Encoding" menu, you can check the current Encoding and/or Convert to a set of encodings available.

Better use StringBuilder since it is not synchronized and offers therefore better performance. StringBuilder is a drop-in replacement of the older StringBuffer.

This can be achieved purely with JavaScript.

I see the answer I wanted to write has been answered by lynx in comments to the question.

But I'm going to write answer anyway because just like me, people sometimes forget to read the comments.

So, if you just want to get an element's distance (in Pixels) from the top of your screen window, here is what you need to do:

// Fetch the element
var el = document.getElementById("someElement");  

use getBoundingClientRect()

// Use the 'top' property of 'getBoundingClientRect()' to get the distance from top
var distanceFromTop = el.getBoundingClientRect().top; 

Thats it!

Hope this helps someone :)

AFAIK there is no possibility beside from using keys or expect if you are using the command line version ssh. But there are library bindings for the most programming languages like C, python, php, ... . You could write a program in such a language. This way it would be possible to pass the password automatically. But note this is of course a security problem as the password will be stored in plain text in that program

A JSON document basically consists of lists and dictionaries. There is no obvious way to map such a datastructure on a two-dimensional table.

"Knowing about sites which handles such massive traffic gives lots of pointers for architects etc. to keep in mind certain stuff while designing new sites"

I think you can probably learn a lot from the design of Facebook, just as you can from the design of any successful large software system. However, it seems to me that you should not keep the current design of Facebook in mind when designing new systems.

Why do you want to be able to handle the traffic that Facebook has to handle? Odds are that you will never have to, no matter how talented a programmer you may be. Facebook itself was not designed from the start for such massive scalability, which is perhaps the most important lesson to learn from it.

If you want to learn about a non-trivial software system I can recommend the book "Dissecting a C# Application" about the development of the SharpDevelop IDE. It is out of print, but it is available for free online. The book gives you a glimpse into a real application and provides insights about IDEs which are useful for a programmer.

I had the same problem. For me the solution is to delete the remote file and let rsync create again.

df.index

• outputs the row names as pandas Index object.

list(df.index)

• casts to a list.

df.index['Row 2':'Row 5']

• supports label slicing similar to columns.

Late answer, but this is what I use to find and replace inside a text file:

with open("test.txt") as r:
  text = r.read().replace("THIS", "THAT")
with open("test.txt", "w") as w:
  w.write(text)

DEMO

with php you can use two redirections. It works same as refresh in some issues.

you can use a page redirect.php and post your last url to it by GET method (for example). then in redirect.php you can change header to location you`ve sent to it by GET method.

like this: your page:

<?php
header("location:redirec.php?ref=".$your_url);
?>

redirect.php:

<?php
$ref_url=$_GET["ref"];
header("location:redirec.php?ref=".$ref_url);
?>

that worked for me good.

Not only does std::vector make a copy of whatever you're pushing back, but the definition of the collection states that it will do so, and that you may not use objects without the correct copy semantics within a vector. So, for example, you do not use auto_ptr in a vector.

If you set unique parameters, then the cache does not work, for example:

$.ajax({
    url : "my_url",
    data : {
        'uniq_param' : (new Date()).getTime(),
        //other data
    }});

If the program you're using to execute your script needs parameters, you can put them at the end of the #! line:

#!/usr/bin/R --random --switches --f

Not knowing R, I can't test properly, but this seems to work:

axa@artemis:~$ cat r.test
#!/usr/bin/R -q -f
error
axa@artemis:~$ ./r.test
> #!/usr/bin/R -q -f
> error
Error: object "error" not found
Execution halted
axa@artemis:~$

Solution 1 - you need to change your backend to accept your incoming requests

Solution 2 - using Angular proxy see here

Please note this is only for ng serve, you can't use proxy in ng build

Note: the reason it's working via postman is postman doesn't send preflight requests while your browser does.

If you want to call a function on clicking of submit button then you have
to use ajax or jquery,if you want to call your php function after submission of form you can do that as :

<html>
<body>
<form method="post" action="display()">
<input type="text" name="studentname">
<input type="submit" value="click">
</form>
<?php
function display()
{
echo "hello".$_POST["studentname"];
}
if($_SERVER['REQUEST_METHOD']=='POST')
{
       display();
} 
?>
</body>
</html>

Here's the briefest explanation:

A Turing Complete system means a system in which a program can be written that will find an answer (although with no guarantees regarding runtime or memory).

So, if somebody says "my new thing is Turing Complete" that means in principle (although often not in practice) it could be used to solve any computation problem.

Sometimes it's a joke... a guy wrote a Turing Machine simulator in vi, so it's possible to say that vi is the only computational engine ever needed in the world.

I suggest you to use provider. Provide is good when you want to configure it first before to use (against Service/Factory)

Something like:

.provider('Magazines', function() {

    this.url = '/';
    this.urlArray = '/';
    this.organId = 'Default';

    this.$get = function() {
        var url = this.url;
        var urlArray = this.urlArray;
        var organId = this.organId;

        return {
            invoke: function() {
                return ......
            }
        }
    };

    this.setUrl  = function(url) {
        this.url = url;
    };

   this.setUrlArray  = function(urlArray) {
        this.urlArray = urlArray;
    };

    this.setOrganId  = function(organId) {
        this.organId = organId;
    };
});

.config(function(MagazinesProvider){
    MagazinesProvider.setUrl('...');
    MagazinesProvider.setUrlArray('...');
    MagazinesProvider.setOrganId('...');
});

And now controller:

function MyCtrl($scope, Magazines) {        

        Magazines.invoke();

       ....

}

Consider using SCSS. It's full compatible with CSS syntax, so a valid CSS file is also a valid SCSS file. This makes migration easy, just change the suffix. It has numerous enhancements, the most useful being variables and nested selectors.

You need to run it through a pre-processor to convert it to CSS before shipping it to the client.

I've been a hardcore CSS developer for many years now, but since forcing myself to do a project in SCSS, I now won't use anything else.

I catch the close event of the dialog box. This code then removes the <div> (#dhx_combo_list):

open: function(event, ui) { 
  //hide close button.
  $(this).parent().children().children('.ui-dialog-titlebar-close').click(function(){
    $("#dhx_combo_list").remove();
  });
},

Zend Framework can load and edit existing PDF files. I think it supports revisions too.

I use it to create docs in a project, and it works great. Never edited one though.

Check out the doc here

'T' represents a generic type. It means it can accept any type of class. The following article might help:

http://www.15seconds.com/issue/031024.htm

In 2018,

$('#datepicker').datepicker({
    format: "yyyy",
    weekStart: 1,
    orientation: "bottom",
    language: "{{ app.request.locale }}",
    keyboardNavigation: false,
    viewMode: "years",
    minViewMode: "years"
});

By implement this code in your ViewController you can get this effect Actually the trick is , hide the navigationBar when that Controller is launched

- (void)viewWillAppear:(BOOL)animated {
    [self.navigationController setNavigationBarHidden:YES animated:YES];
    [super viewWillAppear:animated];
}

and unhide the navigation bar when user leave that page do this is viewWillDisappear

- (void)viewWillDisappear:(BOOL)animated {
    [self.navigationController setNavigationBarHidden:NO animated:YES];
    [super viewWillDisappear:animated];
}

The method boolean shouldOverrideUrlLoading(WebView view, String url) was deprecated in API 24. If you are supporting new devices you should use boolean shouldOverrideUrlLoading (WebView view, WebResourceRequest request).

You can use both by doing something like this:

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
    newsItem.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            view.loadUrl(request.getUrl().toString());
            return true;
        }
    });
} else {
    newsItem.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    });
}

This might help. It contains many examples which will be useful in understanding.

http://www.w3schools.com/bootstrap/bootstrap_ref_comp_glyphs.asp

SELECT 
    u . *
FROM
    room u
        JOIN
    facilities_r fu ON fu.id_uc = u.id_uc
        AND (fu.id_fu = '4' OR fu.id_fu = '3')
WHERE
    1 and vizibility = '1'
GROUP BY id_uc
ORDER BY u_premium desc , id_uc desc

You must use OR here, not AND.

Since id_fu cannot be equal to 4 and 3, both at once.

It's an old question, but if you wanted to catch a backspace event on input, and not keydown, keypress, or keyup—as I've noticed any one of these break certain functions I've written and cause awkward delays with automated text formatting—you can catch a backspace using inputType:

document.getElementsByTagName('input')[0].addEventListener('input', function(e) {
    if (e.inputType == "deleteContentBackward") {
        // your code here
    }
});

some_string="ABCDEFGHIJKLMNOPQRSTUVWXYZ"
x=3 
res=[some_string[y-x:y] for y in range(x, len(some_string)+x,x)]
print(res)

will produce

['ABC', 'DEF', 'GHI', 'JKL', 'MNO', 'PQR', 'STU', 'VWX', 'YZ']

One thing that really hung me up, was when I inspected this html in the browser, instead of seeing it expanded to something like:

<button ng-click="removeTask(1234)">remove</button>

I saw:

<button ng-click="removeTask(task.id)">remove</button>

However, the latter works!

This is because you are in the "Angular World", when inside ng-click="" Angular all ready knows about task.id as you are inside it's model. There is no need to use Data binding, as in {{}}.

Further, if you wanted to pass the task object itself, you can like:

<button ng-click="removeTask(task)">remove</button>

In Spring 2.1.5 at least, the XML file can be conveniently replaced by annotations. Piggy backing on @Sembrano's answer, I have this. "Look ma, no XML".

It appears I to had list all the classes I need @Autowired in the @ComponentScan

@RunWith(SpringJUnit4ClassRunner.class)
@ComponentScan(
    basePackageClasses = {
            OwnerService.class
            })
@EnableAutoConfiguration
public class OwnerIntegrationTest {
    
    @Autowired
    OwnerService ownerService;
    
    @Test
    public void testOwnerService() {
       Assert.assertNotNull(ownerService);
    }
}

Make sure you image is a relative path such as:

@Url.Content("~/Content/images/myimage.png")

MVC4

<img src="~/Content/images/myimage.png" />

You could convert the byte[] into a Base64 string on the fly.

string base64String = Convert.ToBase64String(imageBytes);

<img src="@String.Format("data:image/png;base64,{0}", base64string)" />

You could use the undocumented

DBCC LOG(databasename, typeofoutput)

where typeofoutput:

0: Return only the minimum of information for each operation -- the operation, its context and the transaction ID. (Default)
1: As 0, but also retrieve any flags and the log record length.
2: As 1, but also retrieve the object name, index name, page ID and slot ID.
3: Full informational dump of each operation.
4: As 3 but includes a hex dump of the current transaction log row.

For example, DBCC LOG(database, 1)

You could also try fn_dblog.

For rolling back a transaction using the transaction log I would take a look at Stack Overflow post Rollback transaction using transaction log.

This will work with either an array, an object or a variable and also escapes the special characters that may break your JS :

function debugToConsole($msg) { 
        echo "<script>console.log(".json_encode($msg).")</script>";
}

Edit : Added json_encode to the echo statement. This will prevent your script from breaking if there are quotes in your $msg variable.

You can use row_number() to get the row number of the row. It uses the over command - the partition by clause specifies when to restart the numbering and the order by selects what to order the row number on. Even if you added an order by to the end of your query, it would preserve the ordering in the over command when numbering.

select *
from mytable
where row_number() over(partition by Name order by AddressLine) = 1

It's always dangerous to have NULL in the IN list - it often behaves as expected for the IN but not for the NOT IN:

IF 1 NOT IN (1, 2, 3, NULL) PRINT '1 NOT IN (1, 2, 3, NULL)'
IF 1 NOT IN (2, 3, NULL) PRINT '1 NOT IN (2, 3, NULL)'
IF 1 NOT IN (2, 3) PRINT '1 NOT IN (2, 3)' -- Prints
IF 1 IN (1, 2, 3, NULL) PRINT '1 IN (1, 2, 3, NULL)' -- Prints
IF 1 IN (2, 3, NULL) PRINT '1 IN (2, 3, NULL)'
IF 1 IN (2, 3) PRINT '1 IN (2, 3)'

use "Content-type: application/x-www-form-urlencoded" instead of "application/json"

Starting with Safari 5/Firefox 4, it’s easiest to use the FormData class:

var data = new FormData();
jQuery.each(jQuery('#file')[0].files, function(i, file) {
    data.append('file-'+i, file);
});

So now you have a FormData object, ready to be sent along with the XMLHttpRequest.

jQuery.ajax({
    url: 'php/upload.php',
    data: data,
    cache: false,
    contentType: false,
    processData: false,
    method: 'POST',
    type: 'POST', // For jQuery < 1.9
    success: function(data){
        alert(data);
    }
});

It’s imperative that you set the contentType option to false, forcing jQuery not to add a Content-Type header for you, otherwise, the boundary string will be missing from it. Also, you must leave the processData flag set to false, otherwise, jQuery will try to convert your FormData into a string, which will fail.

You may now retrieve the file in PHP using:

$_FILES['file-0']

(There is only one file, file-0, unless you specified the multiple attribute on your file input, in which case, the numbers will increment with each file.)

Using the FormData emulation for older browsers

var opts = {
    url: 'php/upload.php',
    data: data,
    cache: false,
    contentType: false,
    processData: false,
    method: 'POST',
    type: 'POST', // For jQuery < 1.9
    success: function(data){
        alert(data);
    }
};
if(data.fake) {
    // Make sure no text encoding stuff is done by xhr
    opts.xhr = function() { var xhr = jQuery.ajaxSettings.xhr(); xhr.send = xhr.sendAsBinary; return xhr; }
    opts.contentType = "multipart/form-data; boundary="+data.boundary;
    opts.data = data.toString();
}
jQuery.ajax(opts);

Create FormData from an existing form

Instead of manually iterating the files, the FormData object can also be created with the contents of an existing form object:

var data = new FormData(jQuery('form')[0]);

Use a PHP native array instead of a counter

Just name your file elements the same and end the name in brackets:

jQuery.each(jQuery('#file')[0].files, function(i, file) {
    data.append('file[]', file);
});

$_FILES['file'] will then be an array containing the file upload fields for every file uploaded. I actually recommend this over my initial solution as it’s simpler to iterate over.

Using constraints layout

1. Add a Guideline
2. Set the percentage to 50%
3. Constrain your view to the Guideline and the parent.

If you are having trouble changing it to a percentage, then see this answer.

You can try this method that is developed by Chucai Yi and Yingli Tian.

They also share a software (which is based on Opencv-1.0 and it should run under Windows platform.) that you can use (though no source code available). It will generate all the text bounding boxes (shown in color shadows) in the image. By applying to your sample images, you will get the following results:

Note: to make the result more robust, you can further merge adjacent boxes together.

Update: If your ultimate goal is to recognize the texts in the image, you can further check out gttext, which is an OCR free software and Ground Truthing tool for Color Images with Text. Source code is also available.

With this, you can get recognized texts like:

load your url helper when you create a function eg,

visibility function_name () {

     $this->load->helper('url');
}

the it will show you errors or a view you loaded.

Generally, using Promise.all() runs requests "async" in parallel. Using await can run in parallel OR be "sync" blocking.

test1 and test2 functions below show how await can run async or sync.

test3 shows Promise.all() that is async.

jsfiddle with timed results - open browser console to see test results

Sync behavior. Does NOT run in parallel, takes ~1800ms:

const test1 = async () => {
  const delay1 = await Promise.delay(600); //runs 1st
  const delay2 = await Promise.delay(600); //waits 600 for delay1 to run
  const delay3 = await Promise.delay(600); //waits 600 more for delay2 to run
};

Async behavior. Runs in paralel, takes ~600ms:

const test2 = async () => {
  const delay1 = Promise.delay(600);
  const delay2 = Promise.delay(600);
  const delay3 = Promise.delay(600);
  const data1 = await delay1;
  const data2 = await delay2;
  const data3 = await delay3; //runs all delays simultaneously
}

Async behavior. Runs in parallel, takes ~600ms:

const test3 = async () => {
  await Promise.all([
  Promise.delay(600), 
  Promise.delay(600), 
  Promise.delay(600)]); //runs all delays simultaneously
};

TLDR; If you are using Promise.all() it will also "fast-fail" - stop running at the time of the first failure of any of the included functions.

Run apt-get install build-essential on your system.

This package depends on other packages considered to be essential for builds and will install them. If you find you have to build packages, this can be helpful to avoid piecemeal resolution of dependencies.

The fastest way is to check if there is a non letter:

if (!/[^a-zA-Z]/.test(word))

Place right_ax before set_ylabel()

ax.right_ax.set_ylabel('AB scale')

You want to do this - set a function that will be executed to respond to the onclick event:

document.getElementById('buttonLED'+id).onclick = function(){ writeLED(1,1); } ;

The things you are doing don't work because:

1. The onclick event handler expects to have a function, here you are assigning a string

   document.getElementById('buttonLED'+id).onclick = "writeLED(1,1)";
   

2. In this, you are assigning as the onclick event handler the result of executing the writeLED(1,1) function:

   document.getElementById('buttonLED'+id).onclick = writeLED(1,1);
   

In my Angular Bootstrap dropdowns I initialize the JSON Array (vm.zoneDropdown) with ng-init (you can also have ng-init inside the directive template) and I pass the Array in a custom src attribute

<custom-dropdown control-id="zone" label="Zona" model="vm.form.zone" src="vm.zoneDropdown"
                         ng-init="vm.getZoneDropdownSrc()" is-required="true" form="farmaciaForm" css-class="custom-dropdown col-md-3"></custom-dropdown>

Inside the controller:

vm.zoneDropdown = [];
vm.getZoneDropdownSrc = function () {
    vm.zoneDropdown = $customService.getZone();
}

And inside the customDropdown directive template(note that this is only one part of the bootstrap dropdown):

<ul class="uib-dropdown-menu" role="menu" aria-labelledby="btn-append-to-body">
    <li role="menuitem" ng-repeat="dropdownItem in vm.src" ng-click="vm.setValue(dropdownItem)">
        <a ng-click="vm.preventDefault($event)" href="##">{{dropdownItem.text}}</a>
    </li>
</ul>

This solution worked for me:

First install django-phone-field

command: pip install django-phone-field

then on models.py

from phone_field import PhoneField
...

class Client(models.Model):
    ...
    phone_number = PhoneField(blank=True, help_text='Contact phone number')

and on settings.py

INSTALLED_APPS = [...,
                  'phone_field'
]

It looks like this in the end

Using MVVM Light Toolkit:

Assuming that there is an Exit command in view model:

ICommand _exitCommand;
public ICommand ExitCommand
{
    get
    {
        if (_exitCommand == null)
            _exitCommand = new RelayCommand<object>(call => OnExit());
        return _exitCommand;
    }
}

void OnExit()
{
     var msg = new NotificationMessageAction<object>(this, "ExitApplication", (o) =>{});
     Messenger.Default.Send(msg);
}

This is received in the view:

Messenger.Default.Register<NotificationMessageAction<object>>(this, (m) => if (m.Notification == "ExitApplication")
{
     Application.Current.Shutdown();
});

On the other hand, I handle Closing event in MainWindow, using the instance of ViewModel:

private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{ 
    if (((ViewModel.MainViewModel)DataContext).CancelBeforeClose())
        e.Cancel = true;
}

CancelBeforeClose checks the current state of view model and returns true if closing should be stopped.

Hope it helps someone.

Using " ; " as delimiter on windows issue got resolved.

java -cp "path of class files; testng jar file path" org.testng.TestNG testng.xml

ex:-

java -cp ".\bin;..\common_lib\*;" org.testng.TestNG testng.xml

I would approach this by using re.match in the following way:

import re
match = re.match(r"([a-z]+)([0-9]+)", 'foofo21', re.I)
if match:
    items = match.groups()
print(items)
>> ("foofo", "21")

No, there is no straightforward way because Python dictionaries do not have a set ordering.

From the documentation:

Keys and values are listed in an arbitrary order which is non-random, varies across Python implementations, and depends on the dictionary’s history of insertions and deletions.

In other words, the 'index' of b depends entirely on what was inserted into and deleted from the mapping before:

>>> map={}
>>> map['b']=1
>>> map
{'b': 1}
>>> map['a']=1
>>> map
{'a': 1, 'b': 1}
>>> map['c']=1
>>> map
{'a': 1, 'c': 1, 'b': 1}

As of Python 2.7, you could use the collections.OrderedDict() type instead, if insertion order is important to your application.

I totally agree with both the question and Martin's answer :). Even in Java, reading javadoc with generics is much harder than it should be due to the extra noise. This is compounded in Scala where implicit parameters are used as in the questions's example code (while the implicits do very useful collection-morphing stuff).

I don't think its a problem with the language per se - I think its more a tooling issue. And while I agree with what Jörg W Mittag says, I think looking at scaladoc (or the documentation of a type in your IDE) - it should require as little brain power as possible to grok what a method is, what it takes and returns. There shouldn't be a need to hack up a bit of algebra on a bit of paper to get it :)

For sure IDEs need a nice way to show all the methods for any variable/expression/type (which as with Martin's example can have all the generics inlined so its nice and easy to grok). I like Martin's idea of hiding the implicits by default too.

To take the example in scaladoc...

def map[B, That](f: A => B)(implicit bf: CanBuildFrom[Repr, B, That]): That

When looking at this in scaladoc I'd like the generic block [B, That] to be hidden by default as well as the implicit parameter (maybe they show if you hover a little icon with the mouse) - as its extra stuff to grok reading it which usually isn't that relevant. e.g. imagine if this looked like...

def map(f: A => B): That

nice and clear and obvious what it does. You might wonder what 'That' is, if you mouse over or click it it could expand the [B, That] text highlighting the 'That' for example.

Maybe a little icon could be used for the [] declaration and (implicit...) block so its clear there are little bits of the statement collapsed? Its hard to use a token for it, but I'll use a . for now...

def map.(f: A => B).: That

So by default the 'noise' of the type system is hidden from the main 80% of what folks need to look at - the method name, its parameter types and its return type in nice simple concise way - with little expandable links to the detail if you really care that much.

Mostly folks are reading scaladoc to find out what methods they can call on a type and what parameters they can pass. We're kinda overloading users with way too much detail right how IMHO.

Here's another example...

def orElse[A1 <: A, B1 >: B](that: PartialFunction[A1, B1]): PartialFunction[A1, B1]

Now if we hid the generics declaration its easier to read

def orElse(that: PartialFunction[A1, B1]): PartialFunction[A1, B1]

Then if folks hover over, say, A1 we could show the declaration of A1 being A1 <: A. Covariant and contravariant types in generics add lots of noise too which can be rendered in a much easier to grok way to users I think.

If it is in RelativeLayout you can use android:layout_toRightOf="@id/<id_of_desired_item>"

Or

If you want to align to the right corner of the device the place android:layout_alignParentRight="true"

If you only have one typeface you would like to add, and want less code to write, you can create a dedicated TextView for your specific font. See code below.

package com.yourpackage;
import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;

public class FontTextView extends TextView {
    public static Typeface FONT_NAME;


    public FontTextView(Context context) {
        super(context);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
        this.setTypeface(FONT_NAME);
    }
    public FontTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
        this.setTypeface(FONT_NAME);
    }
    public FontTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
        this.setTypeface(FONT_NAME);
    }
}

In main.xml, you can now add your textView like this:

<com.yourpackage.FontTextView
    android:id="@+id/tvTimer"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="" />

I'm doing a git repository statistics generator in ruby, it's called git_stats.

You can find examples generated for some repositories on project page.

Here is a list of what it can do:

• General statistics
  • Total files (text and binary)
  • Total lines (added and deleted)
  • Total commits
  • Authors
• Activity (total and per author)
  • Commits by date
  • Commits by hour of day
  • Commits by day of week
  • Commits by hour of week
  • Commits by month of year
  • Commits by year
  • Commits by year and month
• Authors
  • Commits by author
  • Lines added by author
  • Lines deleted by author
  • Lines changed by author
• Files and lines
  • By date
  • By extension

If you have any idea what to add or improve please let me know, I would appreciate any feedback.

I used the following two steps which I found in the comments/posts linked in the other answers:

Step one: Convert the x.509 cert and key to a pkcs12 file

openssl pkcs12 -export -in server.crt -inkey server.key \
               -out server.p12 -name [some-alias] \
               -CAfile ca.crt -caname root

Note: Make sure you put a password on the pkcs12 file - otherwise you'll get a null pointer exception when you try to import it. (In case anyone else had this headache). (Thanks jocull!)

Note 2: You might want to add the -chain option to preserve the full certificate chain. (Thanks Mafuba)

Step two: Convert the pkcs12 file to a Java keystore

keytool -importkeystore \
        -deststorepass [changeit] -destkeypass [changeit] -destkeystore server.keystore \
        -srckeystore server.p12 -srcstoretype PKCS12 -srcstorepass some-password \
        -alias [some-alias]

Finished

OPTIONAL Step zero: Create self-signed certificate

openssl genrsa -out server.key 2048
openssl req -new -out server.csr -key server.key
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

Cheers!

If you don't know exactly how to organize data in Redis, I did some performance tests, including the results parsing. The dictonary I used (d) had 437.084 keys (md5 format), and the values of this form:

{"path": "G:\tests\2687.3575.json",
 "info": {"f": "foo", "b": "bar"},
 "score": 2.5}

First Test (inserting data into a redis key-value mapping):

conn.hmset('my_dict', d)  # 437.084 keys added in 8.98s

conn.info()['used_memory_human']  # 166.94 Mb

for key in d:
    json.loads(conn.hget('my_dict', key).decode('utf-8').replace("'", '"'))
    #  41.1 s

import ast
for key in d:
    ast.literal_eval(conn.hget('my_dict', key).decode('utf-8'))
    #  1min 3s

conn.delete('my_dict')  # 526 ms

Second Test (inserting data directly into Redis keys):

for key in d:
    conn.hmset(key, d[key])  # 437.084 keys added in 1min 20s

conn.info()['used_memory_human']  # 326.22 Mb

for key in d:
    json.loads(conn.hgetall(key)[b'info'].decode('utf-8').replace("'", '"'))
    #  1min 11s

for key in d:
    conn.delete(key)
    #  37.3s

As you can see, in the second test, only 'info' values have to be parsed, because the hgetall(key) already returns a dict, but not a nested one.

And of course, the best example of using Redis as python's dicts, is the First Test

imagecopyresampled() will take a rectangular area from $src_image of width $src_w and height $src_h at position ($src_x, $src_y) and place it in a rectangular area of $dst_image of width $dst_w and height $dst_h at position ($dst_x, $dst_y).

If the source and destination coordinates and width and heights differ, appropriate stretching or shrinking of the image fragment will be performed. The coordinates refer to the upper left corner.

This function can be used to copy regions within the same image. But if the regions overlap, the results will be unpredictable.

- Edit -

If $src_w and $src_h are smaller than $dst_w and $dst_h respectively, thumb image will be zoomed in. Otherwise it will be zoomed out.

<?php
$dst_x = 0;   // X-coordinate of destination point
$dst_y = 0;   // Y-coordinate of destination point
$src_x = 100; // Crop Start X position in original image
$src_y = 100; // Crop Srart Y position in original image
$dst_w = 160; // Thumb width
$dst_h = 120; // Thumb height
$src_w = 260; // Crop end X position in original image
$src_h = 220; // Crop end Y position in original image

// Creating an image with true colors having thumb dimensions (to merge with the original image)
$dst_image = imagecreatetruecolor($dst_w, $dst_h);
// Get original image
$src_image = imagecreatefromjpeg('images/source.jpg');
// Cropping
imagecopyresampled($dst_image, $src_image, $dst_x, $dst_y, $src_x, $src_y, $dst_w, $dst_h, $src_w, $src_h);
// Saving
imagejpeg($dst_image, 'images/crop.jpg');

The mysql command by default uses UNIX sockets to connect to MySQL.

If you're using MariaDB, you need to load the Unix Socket Authentication Plugin on the server side.

You can do it by editing the [mysqld] configuration like this:

[mysqld]
plugin-load-add = auth_socket.so

Depending on distribution, the config file is usually located at /etc/mysql/ or /usr/local/etc/mysql/

Jeffrey Richter written:

Another way to think of this is that the C# compiler automatically assumes that you have the following using directives in all of your source code files:

using int = System.Int32;
using uint = System.UInt32;
using string = System.String;
...

I’ve seen a number of developers confused, not knowing whether to use string or String in their code. Because in C# string (a keyword) maps exactly to System.String (an FCL type), there is no difference and either can be used.

Most of the answers are correct but I want to add little more. The ternary operator is right-associative, which means it can be chained in the following way if … else-if … else-if … else :

function example() {
    return condition1 ? value1
         : condition2 ? value2
         : condition3 ? value3
         : value4;
}

Equivalent to:

function example() {
    if (condition1) { return value1; }
    else if (condition2) { return value2; }
    else if (condition3) { return value3; }
    else { return value4; }
}

Use PDFiumViewer. I searched for a long time till I came up with a similar solution, then I found this clean piece of code that does not rely on sending raw files to the printer (which is bad if they get interpreted as text files..) or using Acrobat or Ghostscript as a helper (both would need to be installed, which is a hassle):

https://stackoverflow.com/a/41751184/586754

PDFiumViewer comes via nuget, the code example above is complete. Pass in null values for using the default printer.

While Fosco's answer is not wrong there is a case to be considered with this one: mixed arrays. Imagine I have an array like this:

$a = array(
  "nice",
  "car" => "fast",
  "none"
);

Now, PHP allows this kind of syntax but it has one problem: if I run Fosco's code I get 0 which is wrong for me, but why this happens?
Because when doing comparisons between strings and integers PHP converts strings to integers (and this is kinda stupid in my opinion), so when array_search() searches for the index it stops at the first one because apparently ("car" == 0) is true.
Setting array_search() to strict mode won't solve the problem because then array_search("0", array_keys($a)) would return false even if an element with index 0 exists.
So my solution just converts all indexes from array_keys() to strings and then compares them correctly:

echo array_search("car", array_map("strval", array_keys($a)));

Prints 1, which is correct.

EDIT:
As Shaun pointed out in the comment below, the same thing applies to the index value, if you happen to search for an int index like this:

$a = array(
  "foo" => "bar",
  "nice",
  "car" => "fast",
  "none"
);
$ind = 0;
echo array_search($ind, array_map("strval", array_keys($a)));

You will always get 0, which is wrong, so the solution would be to cast the index (if you use a variable) to a string like this:

$ind = 0;
echo array_search((string)$ind, array_map("strval", array_keys($a)));

I created a method fixUntrustCertificate(), so when I am dealing with a domain that is not in trusted CAs you can invoke the method before the request. This code will gonna work after java1.4. This method applies for all hosts:

I will use collection.save(the_changed_dict) this way. I've just tested this, and it still works for me. The following is quoted directly from pymongo doc.:

save(to_save[, manipulate=True[, safe=False[, **kwargs]]])

Save a document in this collection.

If to_save already has an "_id" then an update() (upsert) operation is performed and any existing document with that "_id" is overwritten. Otherwise an insert() operation is performed. In this case if manipulate is True an "_id" will be added to to_save and this method returns the "_id" of the saved document. If manipulate is False the "_id" will be added by the server but this method will return None.

The session is a server side thing, you cannot access it using jQuery. You can write an Http handler (that will share the sessionid if any) and return the value from there using $.ajax.

# ## The cmds with titles to be closed.
titles= ["Ploter", "scanFolder"]

# ## Find the PIDs of the cmds with the above titles.
PIDList = []
for line in tasks:
    for title in titles:
        if  title in line['Window Title']:
           print line['Window Title']       
           PIDList.append(line['PID'])

for id in PIDList:
    os.system('taskkill /pid ' + id ) 

Hope it helps. Their might be numerous better solutions to mine.

Scripts are raw java embedded in the page code, and if you declare variables in your scripts, then they become local variables embedded in the page.

In contrast, JSTL works entirely with scoped attributes, either at page, request or session scope. You need to rework your scriptlet to fish test out as an attribute:

<c:set var="test" value="test1"/>
<%
  String resp = "abc";
  String test = pageContext.getAttribute("test");
  resp = resp + test;
  pageContext.setAttribute("resp", resp);
%>
<c:out value="${resp}"/>

If you look at the docs for <c:set>, you'll see you can specify scope as page, request or session, and it defaults to page.

Better yet, don't use scriptlets at all: they make the baby jesus cry.

I can't remember the last time if ever, I was grateful of the fact HttpWebRequest threw exceptions for status codes >= 400. To get around these issues you need to catch the exceptions immediately, and map them to some non-exception response mechanisms in your code...boring, tedious and error prone in itself. Whether it be communicating with a database, or implementing a bespoke web proxy, its 'nearly' always desirable that the Http driver just tell your application code what was returned, and leave it up to you to decide how to behave.

Hence HttpClient is preferable.

If you want to delete all of them by using "git rm". This is what I do:

git ls-files --deleted -z | xargs -0 git rm

This query lists of all the files that have been removed and deletes them from your git repository. Hope it helps.

You are confusing regular expression with shell globbing. If you want to use regular expression to match file names you could do:

$ ls | egrep '.+\..+'

You need to change the password directly in the database because at mysql the users and their profiles are saved in the database.

So there are several ways. At phpMyAdmin you simple go to user admin, choose root and change the password.

To take the definitions the other mentioned earlier a bit further, how about this perspective...

LDAP is Lightweight Directory Access Protocol. DAP, is an X.500 notion, and in X.500 is VERY heavy weight! (It sort of requires a full 7 layer ISO network stack, which basically only IBM's SNA protocol ever realistically implemented).

There are many other approaches to DAP. Novell has one called NDAP (NCP Novell Core Protocols are the transport, and NDAP is how it reads the directory).

LDAP is just a very lightweight DAP, as the name suggests.

I simply use:

setTimeout(function(){
    //reference/manipulate DOM here
});

And unlike document.addEventListener("DOMContentLoaded" //etc as in the very top answer, it works as far back as IE9 -- http://caniuse.com/#search=DOMContentLoaded only indicates as recently as IE11.

Interestingly I stumbled upon this setTimeout solution in 2009: Is checking for the readiness of the DOM overkill?, which probably could have been worded slightly better, as I meant "is it overkill to use various frameworks' more complicated approaches to check for the readiness of the DOM".

My best explanation for why this technique works is that, when the script with such a setTimeout has been reached, the DOM is in the middle of being parsed, so execution of the code within the setTimeout gets deferred until that operation is finished.

I was having the same problem too, how to debug JavaScript that is inside <script> tags. But then I found it under the Sources tab, called "(index)", with parenthesis. Click the line number to set breakpoints.

This is Chrome 71.

This is working for me on Centos

First: in file /etc/httpd/conf/httpd.conf

add

Listen 8079 

after

Listen 80

This till your server to listen to the port 8079

Second: go to your virtual host for ex. /etc/httpd/conf.d/vhost.conf

and add this code below

<VirtualHost *:8079>
   DocumentRoot /var/www/html/api_folder
   ServerName example.com
   ServerAlias www.example.com
   ServerAdmin [email protected]
   ErrorLog logs/www.example.com-error_log
   CustomLog logs/www.example.com-access_log common
</VirtualHost>

This mean when you go to your www.example.com:8079 redirect to

/var/www/html/api_folder

But you need first to restart the service

sudo service httpd restart

sh  -n   script-name 

Run this. If there are any syntax errors in the script, then it returns the same error message. If there are no errors, then it comes out without giving any message. You can check immediately by using echo $?, which will return 0 confirming successful without any mistake.

It worked for me well. I ran on Linux OS, Bash Shell.

If you face this issue in Linux, one of the common reasons can be that the folder "anaconda3" or "anaconda2" has root ownership. This prevents other users from writing into the folder. This can be resolved by changing the ownership of the folder from root to "USER" by running the command:

sudo chown -R $USER:$USER anaconda3

or sudo chown -R $USER:$USER <path of anaconda 3/2 folder>

Note: How to figure out whether a folder has root ownership? -- There will be a lock symbol on the top right corner of the respective folder. Or right-click on the folder->properties and you will be able to see the owner details

The -R argument lets the $USER access all the folders and files within the folder anaconda3 or anaconda2 or any respective folder. It stands for "recursive".

You will need to return the result of RedirectToAction.

1. Go to Build -> Generate Signed APK in Android Studio.
2. In the new window appeared, click on Create new... button.
3. Next enter details as like shown below and click OK -> Next.
4. Select the Build Type as release and click Finish button.
5. Wait until APK generated successfully message is displayed as like shown below.
6. Click on Show in Explorer to see the signed APK file.

IIRC ...

setSize sets the size of the component.

setPreferredSize sets the preferred size. The Layoutmanager will try to arrange that much space for your component.

It depends on whether you're using a layout manager or not ...

When writing queries with our server LIKE or INSTR (or CHARINDEX in T-SQL) takes too long, so we use LEFT like in the following structure:

select *
from little
left join big
on left( big.key, len(little.key) ) = little.key

I understand that might only work with varying endings to the query, unlike other suggestions with '%' + b + '%', but is enough and much faster if you only need b+'%'.

Another way to optimize it for speed (but not memory) is to create a column in "little" that is "len(little.key)" as "lenkey" and user that instead in the query above.

Since we're all guessing, I might as well give mine: I've always thought it stood for Python. That may sound pretty stupid -- what, P for Python?! -- but in my defense, I vaguely remembered this thread [emphasis mine]:

Subject: Claiming (?P...) regex syntax extensions

From: Guido van Rossum ([email protected])

Date: Dec 10, 1997 3:36:19 pm

I have an unusual request for the Perl developers (those that develop the Perl language). I hope this (perl5-porters) is the right list. I am cc'ing the Python string-sig because it is the origin of most of the work I'm discussing here.

You are probably aware of Python. I am Python's creator; I am planning to release a next "major" version, Python 1.5, by the end of this year. I hope that Python and Perl can co-exist in years to come; cross-pollination can be good for both languages. (I believe Larry had a good look at Python when he added objects to Perl 5; O'Reilly publishes books about both languages.)

As you may know, Python 1.5 adds a new regular expression module that more closely matches Perl's syntax. We've tried to be as close to the Perl syntax as possible within Python's syntax. However, the regex syntax has some Python-specific extensions, which all begin with (?P . Currently there are two of them:

(?P<foo>...) Similar to regular grouping parentheses, but the text
matched by the group is accessible after the match has been performed, via the symbolic group name "foo".

(?P=foo) Matches the same string as that matched by the group named "foo". Equivalent to \1, \2, etc. except that the group is referred
to by name, not number.

I hope that this Python-specific extension won't conflict with any future Perl extensions to the Perl regex syntax. If you have plans to use (?P, please let us know as soon as possible so we can resolve the conflict. Otherwise, it would be nice if the (?P syntax could be permanently reserved for Python-specific syntax extensions. (Is there some kind of registry of extensions?)

to which Larry Wall replied:

[...] There's no registry as of now--yours is the first request from outside perl5-porters, so it's a pretty low-bandwidth activity. (Sorry it was even lower last week--I was off in New York at Internet World.)

Anyway, as far as I'm concerned, you may certainly have 'P' with my blessing. (Obviously Perl doesn't need the 'P' at this point. :-) [...]

So I don't know what the original choice of P was motivated by -- pattern? placeholder? penguins? -- but you can understand why I've always associated it with Python. Which considering that (1) I don't like regular expressions and avoid them wherever possible, and (2) this thread happened fifteen years ago, is kind of odd.

To loop over the key/values, use a for in loop:

for (let key in myDictionary) {
    let value = myDictionary[key];
    // Use `key` and `value`
}

Set height and width parameters in CSS file

.ImageStyle{_x000D_
_x000D_
    max-height: 17vw;_x000D_
    min-height: 17vw;_x000D_
    max-width:17vw;_x000D_
    min-width: 17vw;_x000D_

Right from the PHP Docs: PHP 5.3 Windows binaries uses the static version of the MCrypt library, no DLL are needed.

This is ok but do not split the updateResources into different versions, just use the solution below (kotlin). Key is in "Configuration(context.resources.configuration)" it makes deep copy.

100% solution for API 21+. I have not tested for lower ones, but should work.

private fun updateResources(context: Context, language: String): Context {
    return Configuration(context.resources.configuration).run {
        Locale.setDefault(Locale(language).also { locale ->
            setLocale(locale)
        }).let {
            context.createConfigurationContext(this)
        }
    }
}

I have met with the exact same problem. And it turns out that the configuration file generated by gradle asks for java1.7.
While my system has java1.8 installed.

After modifying the compiler compliance level to 1.8. All things are working as expected.

There's no history in the database itself,but if you are using DataGrip data management tool then you can check the history thats your run in the datagrip.

you CAN give it environment variables. Just preppend env: before the variable name, like this:

value="${env:MY_HOME}/logs/message.log"

1. Right click on Drawable
2. Select New ---> Directory
3. Enter the directory name. Eg: logo.png(the location will already show the drawable folder by default)
4. Copy and paste the images directly into the drawable folder. While pasting you get an option to choose mdpi/xhdpi/xxhdpi etc for each of the images from a list. Select the appropriate option and enter the name of the image. Make sure to keep the same name as the directory name i.e logo.png
5. Do the same for the remaining images. All of them will be placed under the logo.png main folder.

WPF takes a slightly different approach than WinForms here. Instead of having the automation of a object built into the API, they have a separate class for each object that is responsible for automating it. In this case you need the ButtonAutomationPeer to accomplish this task.

ButtonAutomationPeer peer = new ButtonAutomationPeer(someButton);
IInvokeProvider invokeProv = peer.GetPattern(PatternInterface.Invoke) as IInvokeProvider;
invokeProv.Invoke();

Here is a blog post on the subject.

Note: IInvokeProvider interface is defined in the UIAutomationProvider assembly.

Using npm

Latest version while still respecting the semver in your package.json: npm update <package-name>. So, if your package.json says "react": "^15.0.0" and you run npm update react your package.json will now say "react": "^15.6.2" (the currently latest version of react 15).

But since you want to go from react 15 to react 16, that won't do. Latest version regardless of your semver: npm install --save react@latest.

If you want a specific version, you run npm install --save react@<version> e.g. npm install --save [email protected].

https://docs.npmjs.com/cli/install

Using yarn

Latest version while still respecting the semver in your package.json: yarn upgrade react.

Latest version regardless of your semver: yarn upgrade react@latest.

If you are looking for an objective analysis of both the editors, look at their origins and the philosophy behind their respective designs. Think, which one would suit you better and learn it (and learn it and learn it, because it takes time before you being to discover its true utility as against any IDE). An Introduction to Display Editing with Vi was written by Bill Joy and Mark Horton and he explains why he choose modal design and rationale for various key strokes ( it helps me to remember that CTRL-W +W (will switch to next Window and it will same for CTRL W+ CTRL W, just in case you held the CTRL key for a longer duration.

Here is a link to Emacs timeline and has the reference to Multics Emacs paper. Hereis RMS paper on Emacs, where I see the stress is on a programmable text editor (even way back in 1981 and before).

I have not read the emacs papers, but have read Bill Joy's vi paper a couple of times. Both are old, but still you will get the philosophy and you might choose to use the current tool (vim 7.x or emacs 25?)

Edit: I forgot to mention that it takes patience and imagination to read both these papers as it takes you back in time while reading it. But it is worth.

I strongly recommend Perlbrew. It lets you run multiple versions of Perl, install packages, hack Perl internals if you want to, all regular user permissions.

Based on Wakas Bukhary answer, you could make it async by puting the last line in the response scope.

$('#myform').submit(function(event) {

  event.preventDefault(); //this will prevent the default submit
  var _this = $(this); //store form so it can be accessed later

  $.ajax('GET', 'url').then(function(resp) {

    // your code here 

   _this.unbind('submit').submit(); // continue the submit unbind preventDefault
  })  
}

Use immutableJS

import { fromJS } from 'immutable';

// An object we want to clone
let objA = { 
   a: { deep: 'value1', moreDeep: {key: 'value2'} } 
};

let immB = fromJS(objA); // Create immutable Map
let objB = immB.toJS(); // Convert to plain JS object

console.log(objA); // Object { a: { deep: 'value1', moreDeep: {key: 'value2'} } }
console.log(objB); // Object { a: { deep: 'value1', moreDeep: {key: 'value2'} } }

// objA and objB are equalent, but now they and their inner objects are undependent
console.log(objA === objB); // false
console.log(objA.a === objB.a); // false
console.log(objA.moreDeep === objB.moreDeep); // false

Or lodash/merge

import merge from 'lodash/merge'

var objA = {
    a: [{ 'b': 2 }, { 'd': 4 }]
};
// New deeply cloned object:
merge({}, objA ); 

// We can also create new object from several objects by deep merge:
var objB = {
    a: [{ 'c': 3 }, { 'e': 5 }]
};
merge({}, objA , objB ); // Object { a: [{ 'b': 2, 'c': 3 }, { 'd': 4, 'e': 5 }] }

You can either write a spin loop (a loop that just loops for a long period of time performing some sort of computation to delay the function) or use:

setTimeout("Func1()", 3000);

This will call 'Func1()' after 3 seconds.

Edit:

Credit goes to the commenters, but you can pass anonymous functions to setTimeout.

setTimeout(function() {
   //Do some stuff here
}, 3000);

This is much more efficient and does not invoke javascript's eval function.

I have solved this issue as follows:

removed from chrome extension and install ext again. It will work ISA

tuple(set([6, 7, 8, 9, 10, 11, 12]).difference([6, 9, 12]))

It's very simple javascript code to trigger a download for the user:

window.open("<insert URL here>")

You don't want/need axios for this operation; it should be standard to just let the browser do it's thing.

Note: If you need authorisation for the download then this might not work. I'm pretty sure you can use cookies to authorise a request like this, provided it's within the same domain, but regardless, this might not work immediately in such a case.

As for whether it's possible... not with the in-built file downloading mechanism, no.

def f(x) -> str:
return x+4

print(f(45))

# will give the result : 
49

# or with other words '-> str' has NO effect to return type:

print(f(45).__class__)

<class 'int'>

This answer outlines two ways to workaround APIs that don't support CORS:

• Use a CORS Proxy
• Use JSONP if the API Supports it

One workaround is to use a CORS PROXY:

angular.module("app",[])
.run(function($rootScope,$http) { 
     var proxy = "//cors-anywhere.herokuapp.com";
     var url = "http://api.ipify.org/?format=json";
     $http.get(proxy +'/'+ url)
       .then(function(response) {
         $rootScope.response = response.data;
     }).catch(function(response) {
         $rootScope.response = 'ERROR: ' + response.status;
     })     
})

<script src="//unpkg.com/angular/angular.js"></script>
<body ng-app="app">
   Response = {{response}}
</body>

For more information, see

• GitHub: CORS Anywhere

Use JSONP if the API supports it:

 var url = "//api.ipify.org/";
 var trust = $sce.trustAsResourceUrl(url);
 $http.jsonp(trust,{params: {format:'jsonp'}})
   .then(function(response) {
     console.log(response);
     $scope.response = response.data;
 }).catch(function(response) {
     console.log(response);
     $scope.response = 'ERROR: ' + response.status;
 })

• AngularJS $http Service API Reference - $http.jsonp

then() function is related to "Javascript promises" that are used in some libraries or frameworks like jQuery or AngularJS.

A promise is a pattern for handling asynchronous operations. The promise allows you to call a method called "then" that lets you specify the function(s) to use as the callbacks.

For more information see: http://wildermuth.com/2013/8/3/JavaScript_Promises

And for Angular promises: http://liamkaufman.com/blog/2013/09/09/using-angularjs-promises/

Your code doesn't work (parse) because you have an extra ) at the end that causes a Parse Error. Count, you have 2 ( and 3 ). It would work fine if you fix that, but strtotime() returns a timestamp, so to get a human readable time use date().

$selectedTime = "9:15:00";
$endTime = strtotime("+15 minutes", strtotime($selectedTime));
echo date('h:i:s', $endTime);

Get an editor that will syntax highlight and show unmatched parentheses, braces, etc.

To just do straight time without any TZ or DST and add 15 minutes (read zerkms comment):

 $endTime = strtotime($selectedTime) + 900;  //900 = 15 min X 60 sec

Still, the ) is the main issue here.

simply run following on terminal if you don't have pip installed on your mac.

sudo easy_install pip

download python 3 here: python3

once you're done with these 2 steps, make sure to run the following to verify whether you've installed them successfully.

python3 --version
pip3 --version

Ganymede's version of WTP includes a revamped Javascript editor that's worth a try. The key version numbers are Eclipse 3.4 and WTP 3.0. See http://live.eclipse.org/node/569

If you are using netbeans 7 and greater with oracle xe do the following on netbeans :

1. go to services tab
2. under servers, remove glassfish
3. add back glassfish server
4. input port number 9090 for http access

Glassfish can use that one if available or some random port number is created

In Winform App(C#):

static string strFilesLoc = Path.GetFullPath(Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), @"..\..\")) + "Resources\\";

            {
                var result = File.ReadAllText(strFilesLoc + "FontFamily.txt").Trim();
                string[] items = result.Split(new char[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);

For those people using Python, you might consider Selenium Wire, a library for inspecting requests made by the browser during a test.

You get access to requests via the driver.requests attribute:

from seleniumwire import webdriver  # Import from seleniumwire

# Create a new instance of the Firefox driver
driver = webdriver.Firefox()

# Go to the Google home page
driver.get('https://www.google.com')

# Access requests via the `requests` attribute
for request in driver.requests:
    if request.response:
        print(
            request.url,
            request.response.status_code,
            request.response.headers['Content-Type']
        )

Prints:

https://www.google.com/ 200 text/html; charset=UTF-8
https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_120x44dp.png 200 image/png

...

The library gives you the ability to access headers, status code, body content, as well as the ability to modify headers and rewrite URLs.

Using .one ensures this is done only once and not repeatedly.

$(window).one("focus", function() {
    localStorage.clear();
});

It is okay to put several document.ready event listeners (if you need other events to execute multiple times) as long as you do not overdo it, for the sake of readability.

.one is especially useful when you want local storage to be cleared only once the first time a web page is opened or when a mobile application is installed the first time.

   // Fired once when document is ready
   $(document).one('ready', function () {
       localStorage.clear();
   });

If you want to assign dynamic bitmap image to bitmap variables

Example for kotlin

backgroundImage = Glide.with(applicationContext).asBitmap().load(PresignedUrl().getUrl(items!![position].img)).into(100, 100).get();

The above answers did not work for me

.asBitmap should be before the .load("http://....")

VBA uses a garbage collector which is implemented by reference counting.

There can be multiple references to a given object (for example, Dim aw = ActiveWorkbook creates a new reference to Active Workbook), so the garbage collector only cleans up an object when it is clear that there are no other references. Setting to Nothing is an explicit way of decrementing the reference count. The count is implicitly decremented when you exit scope.

Strictly speaking, in modern Excel versions (2010+) setting to Nothing isn't necessary, but there were issues with older versions of Excel (for which the workaround was to explicitly set)

I recommend this script by David Underhill, worked like a charm for me.

It adds these commands in addition natacado's filter-branch to clean up the mess it leaves behind:

rm -rf .git/refs/original/
git reflog expire --all
git gc --aggressive --prune

Full script (all credit to David Underhill)

#!/bin/bash
set -o errexit

# Author: David Underhill
# Script to permanently delete files/folders from your git repository.  To use 
# it, cd to your repository's root and then run the script with a list of paths
# you want to delete, e.g., git-delete-history path1 path2

if [ $# -eq 0 ]; then
    exit 0
fi

# make sure we're at the root of git repo
if [ ! -d .git ]; then
    echo "Error: must run this script from the root of a git repository"
    exit 1
fi

# remove all paths passed as arguments from the history of the repo
files=$@
git filter-branch --index-filter \
"git rm -rf --cached --ignore-unmatch $files" HEAD

# remove the temporary history git-filter-branch
# otherwise leaves behind for a long time
rm -rf .git/refs/original/ && \
git reflog expire --all && \
git gc --aggressive --prune

The last two commands may work better if changed to the following:

git reflog expire --expire=now --all && \
git gc --aggressive --prune=now

See my answer to Stack Overflow question Finish All previous activities.

What you need is to add the Intent.FLAG_CLEAR_TOP. This flag makes sure that all activities above the targeted activity in the stack are finished and that one is shown.

Another thing that you need is the SINGLE_TOP flag. With this one you prevent Android from creating a new activity if there is one already created in the stack.

Just be wary that if the activity was already created, the intent with these flags will be delivered in the method called onNewIntent(intent) (you need to overload it to handle it) in the target activity.

Then in onNewIntent you have a method called restart or something that will call finish() and launch a new intent toward itself, or have a repopulate() method that will set the new data. I prefer the second approach, it is less expensive and you can always extract the onCreate logic into a separate method that you can call for populate.

What I would use is

char *s = "abcd";

You can also pad the characters left by including a number following the X, such as this: string.format("0x{0:X8}", string_to_modify), which yields "0x00000C20".

function myfunction(){
    $('.classname').fancybox().trigger('click'); 
}

It works for me..

Maybe this can help: Advanced Python Scheduler

Here's a small piece of code from their documentation:

from apscheduler.schedulers.blocking import BlockingScheduler

def some_job():
    print "Decorated job"

scheduler = BlockingScheduler()
scheduler.add_job(some_job, 'interval', hours=1)
scheduler.start()

Before I go on, I have the latest version (v5.0.15) of OS X Server (yes, horrible, I know...however, the web server seems to work A-OK). I searched high and low for days trying to update (or at least get Apache to point to) a new version of PHP. My mcrypt did not work, along with other extensions and I installed and reinstalled PHP countless times from http://php-osx.liip.ch/ and other tutorials until I finally noticed a tid-bit of information written in a comment in one of the many different .conf files OS X Server keeps which was that OS X Server loads it's own custom .conf file before it loads the Apache httpd.conf (located at /etc/apache2/httpd.conf). The server file is located:

/Library/Server/Web/Config/apache2/httpd_server_app.conf

When you open this file, you have to comment out this line like so:

#LoadModule php5_module libexec/apache2/libphp5.so

Then add in the correct path (which should already be installed if you have installed via the http://php-osx.liip.ch/ link):

LoadModule php5_module /usr/local/php5/libphp5.so

After this modification, my PHP finally loaded the correct PHP installation. That being said, if things go wonky, it may be because OS X is made to work off the native installation of PHP at the time of OS X installation. To revert, just undo the change above.

Anyway, hopefully this is helpful for anyone else spending countless hours on this.

try this:

width:360px;
height:360px;
top: 50%; left: 50%;
margin-top: -160px; /* ( ( width / 2 ) * -1 ) */
margin-left: -160px; /* ( ( height / 2 ) * -1 ) */
position:absolute;

Bumming off Chris's idea, another option is to use pseudo elements so you don't need to use an absolutely positioned internal element.

<style>
.square {

<div class="square">
  <h1>Square</h1>
  <p>This div will maintain its aspect ratio.</p>
</div>

I've put together a demo here: http://codepen.io/tcmulder/pen/iqnDr

EDIT:

Now, bumming off of Isaac's idea, it's easier in modern browsers to simply use vw units to force aspect ratio (although I wouldn't also use vh as he does or the aspect ratio will change based on window height).

So, this simplifies things:

<style>
.square {
    /* width within the parent (could use vw instead of course) */
    width: 50%;
    /* set aspect ratio */
    height: 50vw;
}
</style>
<div class="square">
  <h1>Square</h1>
  <p>This div will maintain its aspect ratio.</p>
</div>

I've put together a modified demo here: https://codepen.io/tcmulder/pen/MdojRG?editors=1100

You could also set max-height, max-width, and/or min-height, min-width if you don't want it to grow ridiculously big or small, since it's based on the browser's width now and not the container and will grow/shrink indefinitely.

Note you can also scale the content inside the element if you set the font size to a vw measurement and all the innards to em measurements, and here's a demo for that: https://codepen.io/tcmulder/pen/VBJqLV?editors=1100

Before [locationManager startUpdatingLocation];, add an iOS8 location services request:

if([locationManager respondsToSelector:@selector(requestAlwaysAuthorization)])
    [locationManager requestAlwaysAuthorization];

Edit your app's Info.plist and add key NSLocationAlwaysUsageDescription with the string value that will be displayed to the user (for example, We do our best to preserve your battery life.)

If your app needs location services only while the app is open, replace:

requestAlwaysAuthorization with requestWhenInUseAuthorization and

NSLocationAlwaysUsageDescription with NSLocationWhenInUseUsageDescription.

simply do following command

Earlier when I wasn't granted permission to access the repo, I had also added the SSH pubkey to gitlab. At the point I could access the repo and run go mod vendor, the same problem as your happens. (maybe because of cache)

go mod vendor

go: errors parsing go.mod:
/Users/macos/Documents/sample/go.mod:22: git ls-remote -q https://git.aaa.team/core/some_repo.git in /Users/macos/go/pkg/mod/cache/vcs/a94d20a18fd56245f5d0f9f1601688930cad7046e55dd453b82e959b12d78369: exit status 128:
    fatal: could not read Username for 'https://git.aaa.team': terminal prompts disabled

After a while trying, I decide to remove the SSH key and terminal prompts filling in username and password. Everything is fine then!

On newer Windows OS versions you can use the command

sleep /w2000

in a DOS script (.cmd or .bat) to wait for 2s (2000 ms - substitute the time in ms you need). Be careful to include the /w argument - without it the whole computer is put to sleep! You can use -m instead of /m if you wish and optionally a colon (:) between the w and the number.

this code seems to have address the issue for me. it comes for a streaming class, ergo some of the nomenclature.

You can use the ObjectOutputStream class to write objects to an underlying stream.

outputStream = new ObjectOutputStream(new FileOutputStream(filename));
outputStream.writeObject(x);

And read the Object back like -

inputStream = new ObjectInputStream(new FileInputStream(filename));
x = (int[])inputStream.readObject()

Form elements can be accessed via the form's DOM element by name, not by "id" value. Give your form elements names if you want to access them like that, or else access them directly by "id" value:

document.getElementById("color").disabled = true;

edit — oh also, as pointed out by others, it's just "text", not "TextBox", for the "type" attribute.

You might want to invest a little time in reading some front-end development tutorials.

define function in .bashrc

function gitall() {
    file=${1:-.}
    comment=${2:-update}
    echo $file
    echo $comment
    git add $file && git commit -m '$comment' && git push origin master
}

in your terminal

gitall

default gitall will add all in current git repo

gitall some-file-to-add 'update file'

will add certain file to change, and use custom commit message

This is for SWIFT 3.0 and async. Most answers are sync solution which is gonna block your main thread if you have a very slow connection. This solution is better but not perfect because it rely on Google to check the connectivity so feel free to use an other url.

func checkInternetConnection(completionHandler:@escaping (Bool) -> Void)
{
    if let url = URL(string: "http://www.google.com/")
    {
        var request = URLRequest(url: url)
        request.httpMethod = "HEAD"
        request.cachePolicy = .reloadIgnoringLocalAndRemoteCacheData
        request.timeoutInterval = 5

        let tast = URLSession.shared.dataTask(with: request, completionHandler:
        {
            (data, response, error) in

            completionHandler(error == nil)
        })
        tast.resume()
    }
    else
    {
        completionHandler(true)
    }
}

No CSS required, visible class should like this: visible-md-block not just visible-md and the code should be like this:

<div class="containerdiv hidden-sm hidden-xs visible-md-block visible-lg-block">
    <div class="row">
        <div class="col-xs-4 col-sm-4 col-md-4 col-lg-4 logo">

        </div>
    </div>
</div>

<div class="mobile hidden-md hidden-lg ">
    test
</div>

Extra css is not required at all.

It depends what you want to do with each line. awk is a useful utility for this type of processing. Example:

 ls -l | awk '{print $9, $5}'

.. on my system prints the name and size of each item in the directory.

On Dreamhost, this worked:

<IfModule mod_rewrite.c>

# BEGIN WordPress
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

i had a similar requirement on 1 of the projects where you had to send huge number of emails each day, and the client wanted complete control over html templates for different types of emails.

due to the large number of emails to be sent, performance was a primary concern.

what we came up with was static content in sql server where you save entire html template mark up (along with place holders, like [UserFirstName], [UserLastName] which are replaced with real data at run time) for different types of emails

then we loaded this data in asp.net cache - so we dont read the html templates over and over again - but only when they are actually changed

we gave the client a WYSIWYG editor to modify these templates via a admin web form. whenever updates were made, we reset asp.net cache.

and then we had a seperate table for email logs - where every email to be sent was logged. this table had fields called emailType, emailSent and numberOfTries.

we simply ran a job every 5 minutes for important email types (like new member sign up, forgot password) which need to be sent asap

we ran another job every 15 minutes for less important email types (like promotion email, news email, etc)

this way you dont block your server sending non stop emails and you process mails in batch. once an email is sent you set the emailSent field to 1.

Pattern p = Pattern.compile("-?\\d+");
Matcher m = p.matcher("There are more than -2 and less than 12 numbers here");
while (m.find()) {
  System.out.println(m.group());
}

... prints -2 and 12.

-? matches a leading negative sign -- optionally. \d matches a digit, and we need to write \ as \\ in a Java String though. So, \d+ matches 1 or more digits.

Without any server side solution, Theres is only one way in which a secure page can get something from a insecure page/request and that's thought postMessage and a popup

I said popup cuz the site isn't allowed to mix content. But a popup isn't really mixing. It has it's own window but are still able to communicate with the opener with postMessage.

So you can open a new http-page with window.open(...) and have that making the request for you (that is if the site is using CORS as well)

XDomain came to mind when i wrote this but here is a modern approach using the new fetch api, the advantage is the streaming of large files, the downside is that it won't work in all browser

You put this proxy script on any http page

onmessage = evt => {
  const port = evt.ports[0]

  fetch(...evt.data).then(res => {
    // the response is not clonable
    // so we make a new plain object
    const obj = {
      bodyUsed: false,
      headers: [...res.headers],
      ok: res.ok,
      redirected: res.redurected,
      status: res.status,
      statusText: res.statusText,
      type: res.type,
      url: res.url
    }

    port.postMessage(obj)

    // Pipe the request to the port (MessageChannel)
    const reader = res.body.getReader()
    const pump = () => reader.read()
    .then(({value, done}) => done 
      ? port.postMessage(done)
      : (port.postMessage(value), pump())
    )

    // start the pipe
    pump()
  })
}

Then you open a popup window in your https page (note that you can only do this on a user interaction event or else it will be blocked)

window.popup = window.open(http://.../proxy.html)

create your utility function

function xfetch(...args) {
  // tell the proxy to make the request
  const ms = new MessageChannel
  popup.postMessage(args, '*', [ms.port1])

  // Resolves when the headers comes
  return new Promise((rs, rj) => {

    // First message will resolve the Response Object
    ms.port2.onmessage = ({data}) => {
      const stream = new ReadableStream({
        start(controller) {

          // Change the onmessage to pipe the remaning request
          ms.port2.onmessage = evt => {
            if (evt.data === true) // Done?
              controller.close()
            else // enqueue the buffer to the stream
              controller.enqueue(evt.data)
          }
        }
      })

      // Construct a new response with the 
      // response headers and a stream
      rs(new Response(stream, data))
    }
  })
}

And make the request like you normally do with the fetch api

xfetch('http://httpbin.org/get')
  .then(res => res.text())
  .then(console.log)

String string = "This is test string on web";
String splitData[] = string.split("\\s", 2);

Result ::
splitData[0] =>  This
splitData[1] =>  is test string  


String string = "This is test string on web";
String splitData[] = string.split("\\s", 3);

Result ::
splitData[0] =>  This
splitData[1] =>  is
splitData[1] =>  test string on web

By default split method create n number's of arrays on the basis of given regex. But if you want to restrict number of arrays to create after a split than pass second argument as an integer argument.

This might be because of the transitive dependencies.

Try to add/ remove the scope from the JSTL library.

This worked for me!

Modern linear algebra libraries include optimized versions of the most common operations. Many of them include dynamic CPU dispatch, which chooses the best implementation for the hardware at program execution time (without compromising on portability).

This is commonly a better alternative to performing manual optimization of your functinos via vector extensions intrinsic functions. The latter will tie your implementation to a particular hardware vendor and model: if you decide to swap to a different vendor (e.g. Power, ARM) or to a newer vector extensions (e.g. AVX512), you will need to re-implement it again to get the most of them.

MKL transposition, for example, includes the BLAS extensions function imatcopy. You can find it in other implementations such as OpenBLAS as well:

#include <mkl.h>

void transpose( float* a, int n, int m ) {
    const char row_major = 'R';
    const char transpose = 'T';
    const float alpha = 1.0f;
    mkl_simatcopy (row_major, transpose, n, m, alpha, a, n, n);
}

For a C++ project, you can make use of the Armadillo C++:

#include <armadillo>

void transpose( arma::mat &matrix ) {
    arma::inplace_trans(matrix);
}

You can use query parameters for filtering and path parameters for grouping. The following link has good info on this When to use pathParams or QueryParams

You can simply use the Glide API. It avoids all the boilerplate code and the task can be achieved in two lines of code. You refer this link https://blog.mindorks.com/downloading-and-showing-image-with-glide-library-in-android. Enjoy

Try the cex argument:

?par

• cex
  A numerical value giving the amount by which plotting text and symbols should be magnified relative to the default. Note that some graphics functions such as plot.default have an argument of this name which multiplies this graphical parameter, and some functions such as points accept a vector of values which are recycled. Other uses will take just the first value if a vector of length greater than one is supplied.

Here's a jQuery-ised function of Innuendo's answer, ready for use.

$.extend({
    keyCount : function(o) {
        if(typeof o == "object") {
            var i, count = 0;
            for(i in o) {
                if(o.hasOwnProperty(i)) {
                    count++;
                }
            }
            return count;
        } else {
            return false;
        }
    }
});

Can be called like this:

var cnt = $.keyCount({"foo" : "bar"}); //cnt = 1;

Never ever use a "background color" for your listview rows...

this will block every selector action (was my problem!)

good luck!

• Never, ever store local time without its UTC offset (or a reference to the time zone)—examples of how not to do it include FAT32 and struct tm in C.¹
• Understand that a time zone is a combination of
  • a set of UTC offsets (e.g. +0100 in winter, +0200 in summer)
  • rules for when the switchover happens (which may change over time: for example, in the 1990s the EU harmonized the switchover as being on the last Sundays in March and October, at 02:00 standard time/03:00 DST; previously this differed between member states).

¹ Some implementations of struct tm do store the UTC offset, but this has not made it into the standard.

If the DataGridView has been populated by DataSource = x (i.e. is databound) then you need to change the bound data, not the DataGridView cells themselves.

One way of getting to that data from a known row or column is thus:

(YourRow.DataBoundItem as DataRowView).Row['YourColumn'] = NewValue;

You can't. And it's a security measure. Imagine if someone writes JS that sets file input value to some sensitive data file?

re: VMware Workstation support for physical disks vs virtual disks.

I run Player with the VM Disk files on their own dedicated fast hard drive, independent from the OS hard drive. This allows both the OS and Player to simultaneously independently read/write to their own drives, the performance difference is noticeable, and a second WD Black or Raptor or SSD is cheap. Placing the VM disk file on a second drive also works with Microsoft Virtual PC.

In 2018:

<input type="number" pattern="\d*">

is working for both Android and iOS.

I tested on Android (^4.2) and iOS (11.3)
