Open an administrator command prompt, and do this command:

fsutil fsinfo ntfsinfo [your drive]

The Bytes Per Cluster is the equivalent of the allocation unit.

There are also performance problems with short file name creation slowing things down. Microsoft recommends turning off short filename creation if you have more than 300k files in a folder [1]. The less unique the first 6 characters are, the more of a problem this is.

[1] How NTFS Works from http://technet.microsoft.com, search for "300,000"

This is what the "Unhandled exception" says on framework 4.5 when trying to save a file with a long filename:

The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

I did this for a home folder where all the folders are on the desktops of the corresponding users, reachable through a shortcut which did not have the appropriate permissions, so that users couldn't see it even if it was there. So I used Robocopy with the parameter to overwrite the file with the right settings:

FOR /F "tokens=*" %G IN ('dir /b') DO robocopy  "\\server02\Folder with shortcut" "\\server02\home\%G\Desktop" /S /A /V /log+:C:\RobocopyShortcut.txt /XF *.url *.mp3 *.hta *.htm *.mht *.js *.IE5 *.css *.temp *.html *.svg *.ocx *.3gp *.opus *.zzzzz *.avi *.bin *.cab *.mp4 *.mov *.mkv *.flv *.tiff *.tif *.asf *.webm *.exe *.dll *.dl_ *.oc_ *.ex_ *.sy_ *.sys *.msi *.inf *.ini *.bmp *.png *.gif *.jpeg *.jpg *.mpg *.db *.wav *.wma *.wmv *.mpeg *.tmp *.old *.vbs *.log *.bat *.cmd *.zip /SEC /IT /ZB /R:0

As you see there are many file types which I set to ignore (just in case), just set them for your needs or your case scenario.

It was tested on Windows Server 2012, and every switch is documented on Microsoft's sites and others.

If you are using tortoise git you can right-click on a file and git a diff by: Right-clicking on the first file and through the tortoisegit submenu select "Diff later" Then on the second file you can also right-click on this, go to the tortoisegit submenu and then select "Diff with yourfilenamehere.txt"

e.g.

string str = null;
string retString = null;
str = "This is substring test";
retString = str.Substring(8, 9);

This return "substring"

C# substring sample source

"SELECT * FROM tablename WHERE field1 = 'value' && field2 = 'value2'";

becomes

"SELECT * FROM tablename WHERE field1 = ? && field2 = ?";

which is passed to the $mysqli::prepare:

$stmt = $mysqli->prepare(
  "SELECT * FROM tablename WHERE field1 = ? && field2 = ?");
$stmt->bind_param( "ss", $value, $value2); 
// "ss' is a format string, each "s" means string
$stmt->execute();

$stmt->bind_result($col1, $col2);
// then fetch and close the statement

OP comments:

so if i have 5 parameters, i could potentially have "sssis" or something (depending on the types of inputs?)

Right, one type specifier per ? parameter in the prepared statement, all of them positional (first specifier applies to first ? which is replaced by first actual parameter (which is the second parameter to bind_param)).

mysqli will take care of escaping and quoting (I think).

I had sort of the opposite issue as the original poster: I was getting the full path when I only wanted the filename. I used Gabriël's solution to get just the filename, but in the process I discovered why you get the full path on some machines and not others.

Any computer joined to domain will give you back the full path for the filename. I tried this on several different computers with consistent results. I don't have an explanation for why, but at least in my testing it was consistent.

I've always used:

unique = (arr) => arr.filter((item, i, s) => s.lastIndexOf(item) == i);

But recently I had to get unique values for:

["1", 1, "2", 2, "3", 3]

And my old standby didn't cut it, so I came up with this:

uunique = (arr) => Object.keys(Object.assign({}, ...arr.map(a=>({[a]:true}))));

if some directory/folder does not exist but somehow you navigated to that directory in that case you can see this Error,

for example:

• currently, you are in "mno" directory (path = abc/def/ghi/jkl/mno
• run "sudo su" and delete mno
• goto the "ghi" directory and delete "jkl" directory
• now you are in "ghi" directory (path abc/def/ghi)
• run "exit"
• after running the "exit", you will get that Error
• now you will be in "mno"(path = abc/def/ghi/jkl/mno) folder. that does not exist.

so, Generally this Error will show when Directory doesn't exist.

to fix this, simply run "cd;" or you can move to any other directory which exists.

You should consider using a SharedModule for the essential material components of your app, and then import every single module you need to use into your feature modules. I wrote an article on medium explaining how to import Angular material, check it out:

https://medium.com/@benmohamehdi/how-to-import-angular-material-angular-best-practices-80d3023118de

Initially I tried with:

from operator import neg, pos
from time import strptime, mktime
from datetime import datetime, tzinfo, timedelta

class MyUTCOffsetTimezone(tzinfo):
    @staticmethod
    def with_offset(offset_no_signal, signal):  # type: (str, str) -> MyUTCOffsetTimezone
        return MyUTCOffsetTimezone((pos if signal == '+' else neg)(
            (datetime.strptime(offset_no_signal, '%H:%M') - datetime(1900, 1, 1))
          .total_seconds()))

    def __init__(self, offset, name=None):
        self.offset = timedelta(seconds=offset)
        self.name = name or self.__class__.__name__

    def utcoffset(self, dt):
        return self.offset

    def tzname(self, dt):
        return self.name

    def dst(self, dt):
        return timedelta(0)


def to_datetime_tz(dt):  # type: (str) -> datetime
    fmt = '%Y-%m-%dT%H:%M:%S.%f'
    if dt[-6] in frozenset(('+', '-')):
        dt, sign, offset = strptime(dt[:-6], fmt), dt[-6], dt[-5:]
        return datetime.fromtimestamp(mktime(dt),
                                      tz=MyUTCOffsetTimezone.with_offset(offset, sign))
    elif dt[-1] == 'Z':
        return datetime.strptime(dt, fmt + 'Z')
    return datetime.strptime(dt, fmt)

But that didn't work on negative timezones. This however I got working fine, in Python 3.7.3:

from datetime import datetime


def to_datetime_tz(dt):  # type: (str) -> datetime
    fmt = '%Y-%m-%dT%H:%M:%S.%f'
    if dt[-6] in frozenset(('+', '-')):
        return datetime.strptime(dt, fmt + '%z')
    elif dt[-1] == 'Z':
        return datetime.strptime(dt, fmt + 'Z')
    return datetime.strptime(dt, fmt)

Some tests, note that the out only differs by precision of microseconds. Got to 6 digits of precision on my machine, but YMMV:

for dt_in, dt_out in (
        ('2019-03-11T08:00:00.000Z', '2019-03-11T08:00:00'),
        ('2019-03-11T08:00:00.000+11:00', '2019-03-11T08:00:00+11:00'),
        ('2019-03-11T08:00:00.000-11:00', '2019-03-11T08:00:00-11:00')
    ):
    isoformat = to_datetime_tz(dt_in).isoformat()
    assert isoformat == dt_out, '{} != {}'.format(isoformat, dt_out)

Add a div inside your infowindow

<div id=\"mydiv\">YourContent</div>

Then set the size using css. works for me. This asumes all infowindows are the same size!

#mydiv{
width:500px;
height:100px;
}

Contributing to ferrix example,

class Battery():

    def __init__(self, battery_size = 60):
        self.battery_size = battery_size
    def get_range(self):
        if self.battery_size == 70:
            range = 240
        elif self.battery_size == 85:
        range = 270

        message = "This car can go approx " + str(range)
        message += "Fully charge"
        print(message)

My message will not execute, because none of my conditions are fulfill therefore receiving " UnboundLocalError: local variable 'range' referenced before assignment"

def get_range(self):
    if self.battery_size <= 70:
        range = 240
    elif self.battery_size >= 85:
        range = 270

If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:

• Bootstrap Datetime Picker 1

• Bootstrap Datetime Picker 2

The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.

Using reflog didn't work for me.

What worked for me was similar to as described here. Open the file in .git/logs/refs named after the branch that was rebased and find the line that contains "rebase finsihed", something like:

5fce6b51 88552c8f Kris Leech <[email protected]> 1329744625 +0000  rebase finished: refs/heads/integrate onto 9e460878

Checkout the second commit listed on the line.

git checkout 88552c8f

Once confirmed this contained my lost changes I branched and let out a sigh of relief.

git log
git checkout -b lost_changes

Like this:

List<String> list = new ArrayList<String>();

String[] a = list.toArray(new String[0]);

Before Java6 it was recommended to write:

String[] a = list.toArray(new String[list.size()]);

because the internal implementation would realloc a properly sized array anyway so you were better doing it upfront. Since Java6 the empty array is preferred, see .toArray(new MyClass[0]) or .toArray(new MyClass[myList.size()])?

If your list is not properly typed you need to do a cast before calling toArray. Like this:

    List l = new ArrayList<String>();

    String[] a = ((List<String>)l).toArray(new String[l.size()]);

RemoteSigned: all scripts you created yourself will be run, and all scripts downloaded from the Internet will need to be signed by a trusted publisher.

OK, change the policy by simply typing:

Set-ExecutionPolicy RemoteSigned

I was not able to get this working entirely based on the suggestions above. Including the DataTypeAttribute [DataType(DataType.Date)] seemed to solve my issue, see:

Model

[Required]
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:d}", ApplyFormatInEditMode = true)]
public DateTime RptDate { get; set; }

View

@Html.EditorFor(m => m.CLPosts.RptDate)

HTH

string = string.replace(/[&\/\\#,+()$~%.'":*?<>{}]/g,'_');

Alternatively, to change all characters except numbers and letters, try:

string = string.replace(/[^a-zA-Z0-9]/g,'_');

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

Google Calendar Link

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

the parameters being:

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

Update Feb 2018:

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

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

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

New parameters:

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

Notes:

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

With library fpp, you can easily create time series with date format: time_ser=ts(data,frequency=4,start=c(1954,2))

here we start at the 2nd quarter of 1954 with quarter fequency.

It's usually just easier to skip the mouse altogether--or it would be if Sublime didn't mess up multiselect when word wrapping. Here's the official documentation on using the keyboard and mouse for multiple selection. Since it's a bit spread out, I'll summarize it:

Where shortcuts are different in Sublime Text 3, I've made a note. For v3, I always test using the latest dev build; if you're using the beta build, your experience may be different.

If you lose your selection when switching tabs or windows (particularly on Linux), try using Ctrl + U to restore it.

Mouse

Windows/Linux

Building blocks:

• Positive/negative:
  • Add to selection: Ctrl
  • Subtract from selection: Alt In early builds of v3, this didn't work for linear selection.
• Selection type:
  • Linear selection: Left Click
  • Block selection: Middle Click or Shift + Right Click On Linux, middle click pastes instead by default.

Combine as you see fit. For example:

• Add to selection: Ctrl + Left Click (and optionally drag)
• Subtract from selection: Alt + Left Click This didn't work in early builds of v3.
• Add block selection: Ctrl + Shift + Right Click (and drag)
• Subtract block selection: Alt + Shift + Right Click (and drag)

Mac OS X

Building blocks:

• Positive/negative:
  • Add to selection: ?
  • Subtract from selection: ?? (only works with block selection in v3; presumably bug)
• Selection type:
  • Linear selection: Left Click
  • Block selection: Middle Click or ? + Left Click

Combine as you see fit. For example:

• Add to selection: ? + Left Click (and optionally drag)
• Subtract from selection: ?? + Left Click (and drag--this combination doesn't work in Sublime Text 3, but supposedly it works in 2)
• Add block selection: ?? + Left Click (and drag)
• Subtract block selection: ??? + Left Click (and drag)

Keyboard

Windows

• Return to single selection mode: Esc
• Extend selection upward/downward at all carets: Ctrl + Alt + Up/Down
• Extend selection leftward/rightward at all carets: Shift + Left/Right
• Move all carets up/down/left/right, and clear selection: Up/Down/Left/Right
• Undo the last selection motion: Ctrl + U
• Add next occurrence of selected text to selection: Ctrl + D
• Add all occurrences of the selected text to the selection: Alt + F3
• Rotate between occurrences of selected text (single selection): Ctrl + F3 (reverse: Ctrl + Shift + F3)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: Ctrl + Shift + L

Linux

• Return to single selection mode: Esc
• Extend selection upward/downward at all carets: Alt + Up/Down Note that you may be able to hold Ctrl as well to get the same shortcuts as Windows, but Linux tends to use Ctrl + Alt combinations for global shortcuts.
• Extend selection leftward/rightward at all carets: Shift + Left/Right
• Move all carets up/down/left/right, and clear selection: Up/Down/Left/Right
• Undo the last selection motion: Ctrl + U
• Add next occurrence of selected text to selection: Ctrl + D
• Add all occurrences of the selected text to the selection: Alt + F3
• Rotate between occurrences of selected text (single selection): Ctrl + F3 (reverse: Ctrl + Shift + F3)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: Ctrl + Shift + L

Mac OS X

• Return to single selection mode: ? (that's the Mac symbol for Escape)
• Extend selection upward/downward at all carets: ^??, ^?? (See note)
• Extend selection leftward/rightward at all carets: ??/??
• Move all carets up/down/left/right and clear selection: ?, ?, ?, ?
• Undo the last selection motion: ?U
• Add next occurrence of selected text to selection: ?D
• Add all occurrences of the selected text to the selection: ^?G
• Rotate between occurrences of selected text (single selection): ??G (reverse: ???G)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: ??L

Notes for Mac users

On Yosemite and El Capitan, ^?? and ^?? are system keyboard shortcuts by default. If you want them to work in Sublime Text, you will need to change them:

1. Open System Preferences.
2. Select the Shortcuts tab.
3. Select Mission Control in the left listbox.
4. Change the keyboard shortcuts for Mission Control and Application windows (or disable them). I use ^?? and ^??. They defaults are ^? and ^?; adding ^ to those shortcuts triggers the same actions, but slows the animations.

In case you're not familiar with Mac's keyboard symbols:

• ? is the escape key
• ^ is the control key
• ? is the option key
• ? is the shift key
• ? is the command key
• ? et al are the arrow keys, as depicted

The code can be cleaned up, but if you are using a list to store your tuples, any such lookup will be O(N).

If lookup speed is important, you should use a dict to store your tuples. The key should be the 0th element of your tuples, since that's what you're searching on. You can easily create a dict from your list:

my_dict = dict(my_list)

Then, (VALUE, my_dict[VALUE]) will give you your matching tuple (assuming VALUE exists).

It should be

r.append("\n");

But I recommend you to do as below,

r.append(System.getProperty("line.separator"));

System.getProperty("line.separator") gives you system-dependent newline in java. Also from Java 7 there's a method that returns the value directly: System.lineSeparator()

You can pass the tv_sec parameter to some of the formatting function. Have a look at gmtime, localtime(). Then look at snprintf.

I just read the Javadoc 1.5 reference here, and only the code with <and > must be enclosed inside {@code ...}. Here a simple example:

 /** 
 * Bla bla bla, for example:
 *
 * <pre>
 * void X() {
 *    List{@code <String>} a = ...;
 *    ...
 * }
 * </pre>
 *
 * @param ...
 * @return ...
 */
 .... your code then goes here ...

You should check the EOF after reading from file.

fscanf_s                   // read from file
while(condition)           // check EOF
{
   fscanf_s               // read from file
}

To remove the ", " part which is immediately followed by end of string, you can do:

str = str.replaceAll(", $", "");

This handles the empty list (empty string) gracefully, as opposed to lastIndexOf / substring solutions which requires special treatment of such case.

Example code:

String str = "kushalhs, mayurvm, narendrabz, ";
str = str.replaceAll(", $", "");
System.out.println(str);  // prints "kushalhs, mayurvm, narendrabz"

NOTE: Since there has been some comments and suggested edits about the ", $" part: The expression should match the trailing part that you want to remove.

• If your input looks like "a,b,c,", use ",$".
• If your input looks like "a, b, c, ", use ", $".
• If your input looks like "a , b , c , ", use " , $".

I think you get the point.

you can resize it by displaying svg in image tag and size image tag i.e.

<img width="200px" src="lion.svg"></img>

If you are using the Python wrappers, then (assuming your matrix name is mat):

• mat.shape gives you an array of the type- [height, width, channels]

• mat.size gives you the size of the array

Sample Code:

import cv2
mat = cv2.imread('sample.png')
height, width, channel = mat.shape[:3]
size = mat.size

Please check this example here: Accessing Structure Members

There is explained that the right way to do it is like this:

strcpy(s1.name , "Egzona");
printf( "Name : %s\n", s1.name);

Your id will be passed through as #1, #2 etc. However, # is not valid as an ID (CSS selectors prefix IDs with #).

here's a pure Javascript alternative:

var mydiv = document.getElementById("myDiv");
var aTag = document.createElement('a');
aTag.setAttribute('href',"yourlink.htm");
aTag.innerText = "link text";
mydiv.appendChild(aTag);

In version 1.1.1:

• Ctrl+H
• Check the regular exp icon .*
• Search: ><
• Replace: >\n<

Try following command;

ALTER TABLE Person11
ADD CONSTRAINT col_1_def
DEFAULT 'This is not NULL' FOR Address

Use Swift closures :

class TheCell: UITableViewCell {

    var tapCallback: (() -> Void)?

    @IBAction func didTap(_ sender: Any) {
        tapCallback?()
    }
}

extension TheController: UITableViewDataSource {
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            let cell = tableView.dequeueReusableCell(withIdentifier: TheCell.identifier, for: indexPath) as! TheCell {
            cell.tapCallback = {
                //do stuff
            }
            return cell
    }
}

If you want to pursue a "simple" solution, you might find this class I put together useful:

http://www.architectshack.com/TextFileEncodingDetector.ashx

It does the BOM detection automatically first, and then tries to differentiate between Unicode encodings without BOM, vs some other default encoding (generally Windows-1252, incorrectly labelled as Encoding.ASCII in .Net).

As noted above, a "heavier" solution involving NCharDet or MLang may be more appropriate, and as I note on the overview page of this class, the best is to provide some form of interactivity with the user if at all possible, because there simply is no 100% detection rate possible!

Snippet in case the site is offline:

        /*
         * Simple class to handle text file encoding woes (in a primarily English-speaking tech 
         *      world).

         *      are going to read the whole file into memory at some point, then best to pass

         *      
         *  - The UTF-8 detection heuristic only works for western text, as it relies on 
         *      the presence of UTF-8 encoded accented and other characters found in the upper 
         *      ranges of the Latin-1 and (particularly) Windows-1252 codepages.

         * 
         * CHANGELOG:
         *  - 2012-02-03: 
         *    - Simpler methods, removing the silly "DefaultEncoding" parameter (with "??" operator, saves no typing)
         *    - More complete methods
         *      - Optionally return indication of whether BOM was found in "Detect" methods
         *      - Provide straight-to-string method for byte arrays (GetStringFromByteArray)

When you create an App, a file called styles.xml will be created in your res/values folder. If you change the styles, you can change the background, text color, etc for all your layouts. That way you don’t have to go into each individual layout and change the it manually.

styles.xml:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.AppBaseTheme" parent="@android:style/Theme.Light">
    <item name="android:editTextColor">#295055</item> 
    <item name="android:textColorPrimary">#295055</item>
    <item name="android:textColorSecondary">#295055</item>
    <item name="android:textColorTertiary">#295055</item>
    <item name="android:textColorPrimaryInverse">#295055</item>
    <item name="android:textColorSecondaryInverse">#295055</item>
    <item name="android:textColorTertiaryInverse">#295055</item>

     <item name="android:windowBackground">@drawable/custom_background</item>        
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

parent="@android:style/Theme.Light" is Google’s native colors. Here is a reference of what the native styles are: https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/themes.xml

The default Android style is also called “Theme”. So you calling it Theme probably confused the program.

name="Theme.AppBaseTheme" means that you are creating a style that inherits all the styles from parent="@android:style/Theme.Light". This part you can ignore unless you want to inherit from AppBaseTheme again. = <style name="AppTheme" parent="AppBaseTheme">

@drawable/custom_background is a custom image I put in the drawable’s folder. It is a 300x300 png image.

#295055 is a dark blue color.

My code changes the background and text color. For Button text, please look through Google’s native stlyes (the link I gave u above).

Then in Android Manifest, remember to include the code:

<application
android:theme="@style/Theme.AppBaseTheme">

If both are not going to be modified (no adding/deleting items - modifying existing ones is fine as long as you pay heed to threading issues), you can simply pass around data.begin() + 100000 and data.begin() + 101000, and pretend that they are the begin() and end() of a smaller vector.

Or, since vector storage is guaranteed to be contiguous, you can simply pass around a 1000 item array:

T *arrayOfT = &data[0] + 100000;
size_t arrayOfTLength = 1000;

Both these techniques take constant time, but require that the length of data doesn't increase, triggering a reallocation.

I think that you could use a POST or PATCH method to handle this since they typically design for this.

• Using a POST method is typically used to add an element when used on list resource but you can also support several actions for this method. See this answer: How to Update a REST Resource Collection. You can also support different representation formats for the input (if they correspond to an array or a single elements).

  In the case, it's not necessary to define your format to describe the update.

• Using a PATCH method is also suitable since corresponding requests correspond to a partial update. According to RFC5789 (http://tools.ietf.org/html/rfc5789):

  Several applications extending the Hypertext Transfer Protocol (HTTP) require a feature to do partial resource modification. The existing HTTP PUT method only allows a complete replacement of a document. This proposal adds a new HTTP method, PATCH, to modify an existing HTTP resource.

  In the case, you have to define your format to describe the partial update.

I think that in this case, POST and PATCH are quite similar since you don't really need to describe the operation to do for each element. I would say that it depends on the format of the representation to send.

The case of PUT is a bit less clear. In fact, when using a method PUT, you should provide the whole list. As a matter of fact, the provided representation in the request will be in replacement of the list resource one.

You can have two options regarding the resource paths.

• Using the resource path for doc list

In this case, you need to explicitely provide the link of docs with a binder in the representation you provide in the request.

Here is a sample route for this /docs.

The content of such approach could be for method POST:

[
    { "doc_number": 1, "binder": 4, (other fields in the case of creation) },
    { "doc_number": 2, "binder": 4, (other fields in the case of creation) },
    { "doc_number": 3, "binder": 5, (other fields in the case of creation) },
    (...)
]

• Using sub resource path of binder element

In addition you could also consider to leverage sub routes to describe the link between docs and binders. The hints regarding the association between a doc and a binder doesn't have now to be specified within the request content.

Here is a sample route for this /binder/{binderId}/docs. In this case, sending a list of docs with a method POST or PATCH will attach docs to the binder with identifier binderId after having created the doc if it doesn't exist.

The content of such approach could be for method POST:

[
    { "doc_number": 1, (other fields in the case of creation) },
    { "doc_number": 2, (other fields in the case of creation) },
    { "doc_number": 3, (other fields in the case of creation) },
    (...)
]

Regarding the response, it's up to you to define the level of response and the errors to return. I see two levels: the status level (global level) and the payload level (thinner level). It's also up to you to define if all the inserts / updates corresponding to your request must be atomic or not.

• Atomic

In this case, you can leverage the HTTP status. If everything goes well, you get a status 200. If not, another status like 400 if the provided data aren't correct (for example binder id not valid) or something else.

• Non atomic

In this case, a status 200 will be returned and it's up to the response representation to describe what was done and where errors eventually occur. ElasticSearch has an endpoint in its REST API for bulk update. This could give you some ideas at this level: http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/bulk.html.

• Asynchronous

You can also implement an asynchronous processing to handle the provided data. In this case, the HTTP status returns will be 202. The client needs to pull an additional resource to see what happens.

Before finishing, I also would want to notice that the OData specification addresses the issue regarding relations between entities with the feature named navigation links. Perhaps could you have a look at this ;-)

Node.js absolutely does scale on multi-core machines.

Yes, Node.js is one-thread-per-process. This is a very deliberate design decision and eliminates the need to deal with locking semantics. If you don't agree with this, you probably don't yet realize just how insanely hard it is to debug multi-threaded code. For a deeper explanation of the Node.js process model and why it works this way (and why it will NEVER support multiple threads), read my other post.

So how do I take advantage of my 16 core box?

Two ways:

• For big heavy compute tasks like image encoding, Node.js can fire up child processes or send messages to additional worker processes. In this design, you'd have one thread managing the flow of events and N processes doing heavy compute tasks and chewing up the other 15 CPUs.
• For scaling throughput on a webservice, you should run multiple Node.js servers on one box, one per core and split request traffic between them. This provides excellent CPU-affinity and will scale throughput nearly linearly with core count.

Scaling throughput on a webservice

Since v6.0.X Node.js has included the cluster module straight out of the box, which makes it easy to set up multiple node workers that can listen on a single port. Note that this is NOT the same as the older learnboost "cluster" module available through npm.

if (cluster.isMaster) {
  // Fork workers.
  for (var i = 0; i < numCPUs; i++) {
    cluster.fork();
  }
} else {
  http.Server(function(req, res) { ... }).listen(8000);
}

Workers will compete to accept new connections, and the least loaded process is most likely to win. It works pretty well and can scale up throughput quite well on a multi-core box.

If you have enough load to care about multiple cores, then you are going to want to do a few more things too:

1. Run your Node.js service behind a web-proxy like Nginx or Apache - something that can do connection throttling (unless you want overload conditions to bring the box down completely), rewrite URLs, serve static content, and proxy other sub-services.

2. Periodically recycle your worker processes. For a long-running process, even a small memory leak will eventually add up.

3. Setup log collection / monitoring

PS: There's a discussion between Aaron and Christopher in the comments of another post (as of this writing, its the top post). A few comments on that:

• A shared socket model is very convenient for allowing multiple processes to listen on a single port and compete to accept new connections. Conceptually, you could think of preforked Apache doing this with the significant caveat that each process will only accept a single connection and then die. The efficiency loss for Apache is in the overhead of forking new processes and has nothing to do with the socket operations.
• For Node.js, having N workers compete on a single socket is an extremely reasonable solution. The alternative is to set up an on-box front-end like Nginx and have that proxy traffic to the individual workers, alternating between workers for assigning new connections. The two solutions have very similar performance characteristics. And since, as I mentioned above, you will likely want to have Nginx (or an alternative) fronting your node service anyways, the choice here is really between:

Shared Ports: nginx (port 80) --> Node_workers x N (sharing port 3000 w/ Cluster)

vs

Individual Ports: nginx (port 80) --> {Node_worker (port 3000), Node_worker (port 3001), Node_worker (port 3002), Node_worker (port 3003) ...}

There are arguably some benefits to the individual ports setup (potential to have less coupling between processes, have more sophisticated load-balancing decisions, etc.), but it is definitely more work to set up and the built-in cluster module is a low-complexity alternative that works for most people.

Maybe you been given sudo access to only some programs/paths? Then there is no way to do what you want. (unless you will hack it somehow)

If it is not the case then maybe you can write bash script:

cat > myscript.sh
#!/bin/sh
ls -hal /root/ > /root/test.out 

Press ctrl + d :

chmod a+x myscript.sh
sudo myscript.sh

Hope it help.

What have you tried? This should work.

h1 { font-size: 20pt; }
h2 { font-size: 16pt; }

It is very simple with moment below code will return diffrence in hour from current time:

moment().diff('2021-02-17T14:03:55.811000Z', "h")

It's used by std::vector<> because std::vector<> typically allocates more memory than there are objects in the vector<>.

You have to use Convert.FromBase64String to turn a Base64 encoded string into a byte[].

This will search and replace all non ASCII letters:

String resultString = subjectString.replaceAll("[^\\x00-\\x7F]", "");

To copy artifact in specified location use copy instead of get.

mvn org.apache.maven.plugins:maven-dependency-plugin:3.1.2:copy \
  -DrepoUrl=someRepositoryUrl \
  -Dartifact="com.acme:foo:RELEASE:jar" -Dmdep.stripVersion -DoutputDirectory=/tmp/

If you are confident in your input parameters, you can use this single line of code which uses the native Split and Join functions and Excel native Application.pathSeparator.

Split(Join(Split(strPath, "."), Application.pathSeparator), Application.pathSeparator)

If you want a more extensive function, the code below is tested in Windows and should also work on Mac (though not tested). Be sure to also copy the supporting function GetPathSeparator, or modify the code to use Application.pathSeparator. Note, this is a first draft; I should really refactor it to be more concise.

This works:

<div>
    <input type="text" 
        style="margin: 5px; padding: 4px; border: 1px solid; 
        width: 200px; width: calc(100% - 20px);">
</div>

The first 'width' is a fallback rule for older browsers.

Another good use for *args and **kwargs: you can define generic "catch all" functions, which is great for decorators where you return such a wrapper instead of the original function.

An example with a trivial caching decorator:

import pickle, functools
def cache(f):
  _cache = {}
  def wrapper(*args, **kwargs):
    key = pickle.dumps((args, kwargs))
    if key not in _cache:
      _cache[key] = f(*args, **kwargs) # call the wrapped function, save in cache
    return _cache[key] # read value from cache
  functools.update_wrapper(wrapper, f) # update wrapper's metadata
  return wrapper

import time
@cache
def foo(n):
  time.sleep(2)
  return n*2

foo(10) # first call with parameter 10, sleeps
foo(10) # returns immediately

This will show you the table name and column name

select table_name,column_name from information_schema.columns
where column_name like '%breakfast%'

You can slice along the columns of a DataFrame by referring to the names of each column in a list, like so:

data = pandas.DataFrame(np.random.rand(10,5), columns = list('abcde'))
data_ab = data[list('ab')]
data_cde = data[list('cde')]

Well, I totally agree with answers already exist on this point:

• bootstrap.yml is used to save parameters that point out where the remote configuration is and Bootstrap Application Context is created with these remote configuration.

Actually, it is also able to store normal properties just the same as what application.yml do. But pay attention on this tricky thing:

• If you do place properties in bootstrap.yml, they will get lower precedence than almost any other property sources, including application.yml. As described here.

Let's make it clear, there are two kinds of properties related to bootstrap.yml:

• Properties that are loaded during the bootstrap phase. We use bootstrap.yml to find the properties holder (A file system, git repository or something else), and the properties we get in this way are with high precedence, so they cannot be overridden by local configuration. As described here.
• Properties that are in the bootstrap.yml. As explained early, they will get lower precedence. Use them to set defaults maybe a good idea.

So the differences between putting a property on application.yml or bootstrap.yml in spring boot are:

• Properties for loading configuration files in bootstrap phase can only be placed in bootstrap.yml.
• As for all other kinds of properties, place them in application.yml will get higher precedence.

The maven dependency plugin can potentially solve your problem.

If you have a pom with all your project dependencies specified, all you would need to do is run

mvn dependency:copy-dependencies

and you will find the target/dependencies folder filled with all the dependencies, including transitive.

Adding Gustavo's answer from below: To download the dependency sources, you can use

mvn dependency:copy-dependencies -Dclassifier=sources

(via Apache Maven Dependency Plugin doc).

You can not create URI from resources inside of the jar file. You can simply write it to the temp file and then use it (java8):

Path path = File.createTempFile("some", "address").toPath();
Files.copy(ClassLoader.getSystemResourceAsStream("/path/to/resource"), path, StandardCopyOption.REPLACE_EXISTING);

try this (if the Java EE V6)

package crunch;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
@WebServlet(name="hello",urlPatterns={"/hello"})
public class HelloWorld extends HttpServlet {
  public void doGet(HttpServletRequest request,
                    HttpServletResponse response)
      throws ServletException, IOException {
    PrintWriter out = response.getWriter();
    out.println("Hello World");
  }
}

now reach the servlet by http://127.0.0.1:8080/yourapp/hello

where 8080 is default tomcat port, and yourapp is the context name of your applciation

Set the "AutoSizeColumnsMode" property to "Fill".. By default it is set to 'NONE'. Now columns will be filled across the DatagridView. Then you can set the width of other columns accordingly.

DataGridView1.Columns[0].Width=100;// The id column 
DataGridView1.Columns[1].Width=200;// The abbrevation columln
//Third Colulmns 'description' will automatically be resized to fill the remaining 
//space

Depends on your use case.

If you want to do some animation of children blending in, use the react animation add-on: https://facebook.github.io/react/docs/animation.html Otherwise, make the rendering of the children dependent on props and add the props after some delay.

I wouldn't delay in the component, because it will probably haunt you during testing. And ideally, components should be pure.

Usually a good place to start when you run into problems is the manual. The page on configuring email explains that there's a big difference between the PHP mail command running on MSWindows and on every other operating system; it's a good idea when posting a question to provide relevant information on how that part of your system is configured and what operating system it is running on.

Your PHP is configured to talk to an SMTP server - the default for an MSWindows machine, but either you have no MTA installed or it's blocking connections. While for a commercial website running your own MTA robably comes quite high on the list of things to do, it is not a trivial exercise - you really need to know what you're doing to get one configured and running securely. It would make a lot more sense in your case to use a service configured and managed by someone else.

Since you'll be connecting to a remote MTA using a gmail address, then you should probably use Gmail's server; you will need SMTP authenticaton and probably SSL support - neither of which are supported by the mail() function in PHP. There's a simple example here using swiftmailer with gmail or here's an example using phpmailer

The best option according to me is to have key/value pairs file as it could be read from other scripting languages.

Other thing is I would prefer to have an option for comments in the values file - which can be easy achieved with eol option in for /f command.

Here's the example

values file:

;;;;;; file with example values ;;;;;;;;

;; Will be processed by a .bat file
;; ';' can be used for commenting a line

First_Value=value001

;;Do not let spaces arround the equal sign
;; As this makes the processing much easier
;; and reliable

Second_Value=%First_Value%_test

;;as call set will be used in reading script
;; refering another variables will be possible.

Third_Value=Something

;;; end

Reading script:

@echo off

:::::::::::::::::::::::::::::
set "VALUES_FILE=E:\scripts\example.values"
:::::::::::::::::::::::::::::

FOR /F "usebackq eol=; tokens=* delims=" %%# in (
    "%VALUES_FILE%"
) do (
    call set "%%#"
)

echo %First_Value% -- %Second_Value% -- %Third_Value%

By convention, in Python world, the shortcut for numpy is np, so:

In [1]: import numpy as np

In [2]: a = np.array([[1,2],[3,4]])

Second:

In Numpy, dimension, axis/axes, shape are related and sometimes similar concepts:

dimension

In Mathematics/Physics, dimension or dimensionality is informally defined as the minimum number of coordinates needed to specify any point within a space. But in Numpy, according to the numpy doc, it's the same as axis/axes:

In Numpy dimensions are called axes. The number of axes is rank.

In [3]: a.ndim  # num of dimensions/axes, *Mathematics definition of dimension*
Out[3]: 2

axis/axes

the nth coordinate to index an array in Numpy. And multidimensional arrays can have one index per axis.

In [4]: a[1,0]  # to index `a`, we specific 1 at the first axis and 0 at the second axis.
Out[4]: 3  # which results in 3 (locate at the row 1 and column 0, 0-based index)

shape

describes how many data (or the range) along each available axis.

In [5]: a.shape
Out[5]: (2, 2)  # both the first and second axis have 2 (columns/rows/pages/blocks/...) data

Objective-C

You can use (see NSString Class Reference)

- (id)initWithData:(NSData *)data encoding:(NSStringEncoding)encoding

Example:

NSString *myString = [[NSString alloc] initWithData:myData encoding:NSUTF8StringEncoding];

Remark: Please notice the NSData value must be valid for the encoding specified (UTF-8 in the example above), otherwise nil will be returned:

Returns nil if the initialization fails for some reason (for example if data does not represent valid data for encoding).

Prior Swift 3.0

String(data: yourData, encoding: NSUTF8StringEncoding)

Swift 3.0 Onwards

String(data: yourData, encoding: .utf8)

See String#init(data:encoding:) Reference

You could try something like this:

[a-zA-Z]{2}[0-9]{6}

Here is a break down of the expression:

[a-zA-Z]    # Match a single character present in the list below
               # A character in the range between “a” and “z”
               # A character in the range between “A” and “Z”
   {2}         # Exactly 2 times
[0-9]       # Match a single character in the range between “0” and “9”
   {6}         # Exactly 6 times

This will match anywhere in a subject. If you need boundaries around the subject then you could do either of the following:

^[a-zA-Z]{2}[0-9]{6}$

Which ensures that the whole subject matches. I.e there is nothing before or after the subject.

or

\b[a-zA-Z]{2}[0-9]{6}\b

which ensures there is a word boundary on each side of the subject.

As pointed out by @Phrogz, you could make the expression more terse by replacing the [0-9] for a \d as in some of the other answers.

[a-zA-Z]{2}\d{6}

I had the same problem (changing a parameter from the HTTP request in the Filter). I ended up by using a ThreadLocal<String>. In the Filter I have:

class MyFilter extends Filter {
    public static final ThreadLocal<String> THREAD_VARIABLE = new ThreadLocal<>();
    public void doFilter(HttpServletRequest request, HttpServletResponse response, FilterChain chain) {
        THREAD_VARIABLE.set("myVariableValue");
        chain.doFilter(request, response);
    }
}

In my request processor (HttpServlet, JSF controller or any other HTTP request processor), I get the current thread value back:

...
String myVariable = MyFilter.THREAD_VARIABLE.get();
...

Advantages:

• more versatile than passing HTTP parameters (you can pass POJO objects)
• slightly faster (no need to parse the URL to extract the variable value)
• more elegant thant the HttpServletRequestWrapper boilerplate
• the variable scope is wider than just the HTTP request (the scope you have when doing request.setAttribute(String,Object), i.e. you can access the variable in other filtrers.

Disadvantages:

• You can use this method only when the thread which process the filter is the same as the one which process the HTTP request (this is the case in all Java-based servers I know). Consequently, this will not work when
  • doing a HTTP redirect (because the browser does a new HTTP request and there is no way to guarantee that it will be processed by the same thread)
  • processing data in separate threads, e.g. when using java.util.stream.Stream.parallel, java.util.concurrent.Future, java.lang.Thread.
• You must be able to modify the request processor/application

Some side notes:

• The server has a Thread pool to process the HTTP requests. Since this is pool:

  1. a Thread from this thread pool will process many HTTP requests, but only one at a time (so you need either to cleanup you variable after usage or to define it for each HTTP request = pay attention to code such as if (value!=null) { THREAD_VARIABLE.set(value);} because you will reuse the value from the previous HTTP request when value is null : side effects are guaranteed).
  2. There is no guarantee that two requests will be processed by the same thread (it may be the case but you have no guarantee). If you need to keep user data from one request to another request, it would be better to use HttpSession.setAttribute()
• The JEE @RequestScoped internally uses a ThreadLocal, but using the ThreadLocal is more versatile: you can use it in non JEE/CDI containers (e.g. in multithreaded JRE applications)

Change the last line to

q + theme(axis.text.x = element_text(angle = 90, vjust = 0.5, hjust=1))

By default, the axes are aligned at the center of the text, even when rotated. When you rotate +/- 90 degrees, you usually want it to be aligned at the edge instead:

The image above is from this blog post.

Forwarding the example by @ritiek, I'm a beginner in ML too, maybe this kind of formatting will help see the name instead of just class number.

images = np.vstack([x, y])

prediction = model.predict(images)

print(prediction)

i = 1

for things in prediction:  
    if(things == 0):
        print('%d.It is cancer'%(i))
    else:
        print('%d.Not cancer'%(i))
    i = i + 1

Bootstrap 4

Create a responsive navbar sidebar "drawer" in Bootstrap 4?
Bootstrap horizontal menu collapse to sidemenu

Bootstrap 3

I think what you're looking for is generally known as an "off-canvas" layout. Here is the standard off-canvas example from the official Bootstrap docs: http://getbootstrap.com/examples/offcanvas/

The "official" example uses a right-side sidebar the toggle off and on separately from the top navbar menu. I also found these off-canvas variations that slide in from the left and may be closer to what you're looking for..

http://www.bootstrapzero.com/bootstrap-template/off-canvas-sidebar http://www.bootstrapzero.com/bootstrap-template/facebook

Use the astype method.

>>> x = np.array([[1.0, 2.3], [1.3, 2.9]])
>>> x
array([[ 1. ,  2.3],
       [ 1.3,  2.9]])
>>> x.astype(int)
array([[1, 2],
       [1, 2]])

You are writing to memory you do not own:

int board[2][50]; //make an array with 3 columns  (wrong)
                  //(actually makes an array with only two 'columns')
...
for (i=0; i<num3+1; i++)
    board[2][i] = 'O';
          ^

Change this line:

int board[2][50]; //array with 2 columns (legal indices [0-1][0-49])
          ^

To:

int board[3][50]; //array with 3 columns (legal indices [0-2][0-49])
          ^

When creating an array, the value used to initialize: [3] indicates array size.
However, when accessing existing array elements, index values are zero based.

For an array created: int board[3][50];
Legal indices are board[0][0]...board[2][49]

EDIT To address bad output comment and initialization comment

add an additional "\n" for formatting output:

Change:

  ...
  for (k=0; k<50;k++) {
     printf("%d",board[j][k]);
  }
 }

       ...

To:

  ...
  for (k=0; k<50;k++) {
     printf("%d",board[j][k]);
  }
  printf("\n");//at the end of every row, print a new line
}
...  

Initialize board variable:

int board[3][50] = {0};//initialize all elements to zero

While I like Alex Martelli's answer, it doesn't seem Pythonic to me. That is, I thought an important part of being Pythonic is to be easily understandable. With that goal, <= isn't easy to understand.

While it's more characters, using issubset() as suggested by Karl Voigtland's answer is more understandable. Since that method can use a dictionary as an argument, a short, understandable solution is:

foo = {'foo': 1, 'zip': 2, 'zam': 3, 'bar': 4}

if set(('foo', 'bar')).issubset(foo):
    #do stuff

I'd like to use {'foo', 'bar'} in place of set(('foo', 'bar')), because it's shorter. However, it's not that understandable and I think the braces are too easily confused as being a dictionary.

I asked the same question to Xamarin support team, they replied with following:

You can develop an app with Xamarin for commercial usage - there is no extra charge! We only require you to comply with Visual Studio's licensing terms,

which means that in companies of less than 250 employees with less than $1million USD annual revenue, you may use Visual Studio completely free (including Xamarin) for up to 5 developers.

However after you pass those barriers, you would need a Visual Studio license (which includes Xamarin).

Refer the screenshot below.

If BranchA has not been pushed to a remote then you can reorder the commits using rebase and then simply merge. It's preferable to use merge over rebase when possible because it doesn't create duplicate commits.

git checkout BranchA
git rebase -i HEAD~113
... reorder the commits so the 10 you want are first ...
git checkout BranchB
git merge [the 10th commit]

You might also want to look at the DigestUtils class of the apache commons codec project, which provides very convenient methods to create MD5 or SHA digests.

As noted in the release email, linked to from the release tweet and noted in large orange warning that appears on the front page of the documentation, and less orange, but still present, in the readme on the repository and the release on pypi:

xlrd has explicitly removed support for anything other than xls files.

In your case, the solution is to:

• make sure you are on a recent version of Pandas, at least 1.0.1, and preferably the latest release. 1.2 will make his even clearer.
• install openpyxl: https://openpyxl.readthedocs.io/en/stable/
• change your Pandas code to be:

  df1 = pd.read_excel(
       os.path.join(APP_PATH, "Data", "aug_latest.xlsm"),
       engine='openpyxl',
  )
  

Just to add to the other answers, I found that the simplest solution to achieve the rounded corners was to set the following as a background to your Edittext.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <solid android:color="@android:color/white"/>
    <corners android:radius="8dp"/>

</shape>

robocopy yourfolder yourdestination /MON:0

should do it, although you may need some more options. The switch at the end will re-run robocopy if more than 0 changes are seen.

If you like to have the modal fade in rather than slide in (why is it called .fade anyway?) you can overwrite the class in your CSS file or directly in bootstrap.css with this:

.modal.fade{
    -webkit-transition: opacity .2s linear, none;
    -moz-transition: opacity .2s linear, none;
    -ms-transition: opacity .2s linear, none;
    -o-transition: opacity .2s linear, none;
    transition: opacity .2s linear, none;
    top: 50%;
}

If you don't want any effect just remove the fade class from the modal classes.

An easy way to see all the properties on a particular DOM node in Chrome (I'm on v.69) is to right click on the element, select inspect, and then instead of viewing the "Style" tab click on "Properties".

Inside of the Properties tab you will see all the properties for your particular element.

I offen manage css/js plugin with composer which install it under vendor. I symlink those to the web/bundles directory, that's let composer update bundles as needed.

exemple:

1 - symlink once at all (use command fromweb/bundles/

ln -sf vendor/select2/select2/dist/ select2

2 - use asset where needed, in twig template :

{{ asset('bundles/select2/css/fileinput.css) }}

Create a dictionary of (sorted word, list of word). All the words that are in the same list are anagrams of each other.

from collections import defaultdict

def load_words(filename='/usr/share/dict/american-english'):
    with open(filename) as f:
        for word in f:
            yield word.rstrip()

def get_anagrams(source):
    d = defaultdict(list)
    for word in source:
        key = "".join(sorted(word))
        d[key].append(word)
    return d

def print_anagrams(word_source):
    d = get_anagrams(word_source)
    for key, anagrams in d.iteritems():
        if len(anagrams) > 1:
            print(key, anagrams)

word_source = load_words()
print_anagrams(word_source)

Or:

word_source = ["car", "tree", "boy", "girl", "arc"]
print_anagrams(word_source)

Answered here: Convert an image to grayscale in HTML/CSS

You don't even need to use two images which sounds like a pain or an image manipulation library, you can do it with cross browser support (current versions) and just use CSS. This is a progressive enhancement approach which just falls back to color versions on older browsers:

img {
  filter: url(filters.svg#grayscale);
  /* Firefox 3.5+ */
  filter: gray;
  /* IE6-9 */
  -webkit-filter: grayscale(1);
  /* Google Chrome & Safari 6+ */
}
img:hover {
  filter: none;
  -webkit-filter: none;
}

and filters.svg file like this:

<svg xmlns="http://www.w3.org/2000/svg">
  <filter id="grayscale">
    <feColorMatrix type="matrix" values="0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0" />
  </filter>
</svg>

Aria is used to improve the user experience of visually impaired users. Visually impaired users navigate though application using screen reader software like JAWS, NVDA,.. While navigating through the application, screen reader software announces content to users. Aria can be used to add content in the code which helps screen reader users understand role, state, label and purpose of the control

Aria does not change anything visually. (Aria is scared of designers too).

aria-hidden:

aria-hidden attribute is used to hide content for visually impaired users who navigate through application using screen readers (JAWS, NVDA,...).

aria-hidden attribute is used with values true, false.

How To Use:

<i class = "fa fa-books" aria-hidden = "true"></i>

using aria-hidden = "true" on the <i> hides content to screen reader users with no visual change in the application.

aria-label

aria-label attribute is used to communicate the label to screen reader users. Usually search input field does not have visual label (thanks to designers). aria-label can be used to communicate the label of control to screen reader users

How To Use:

<input type = "edit" aria-label = "search" placeholder = "search">

There is no visual change in application. But screen readers can understand the purpose of control

aria-labelledby

Both aria-label and aria-labelledby is used to communicate the label. But aria-labelledby can be used to reference any label already present in the page whereas aria-label is used to communicate the label which i not displayed visually

Approach 1:

<span id = "sd"> Search </span>

<input type = "text" aria-labelledby = "sd">

aria-labelledby can also be used to combine two labels for screen reader users

Approach 2:

<span id = "de"> Billing Address </span>

<span id = "sd"> First Name </span>

<input type = "text" aria-labelledby = "de sd">

The last question has an easy answer:

Meaning I am running R64. If I were running 32 bit R it would return 4. Just because you are running a 64 bit OS does not mean you will be running 64 bit R, and from the error message it appears you are not.

EDIT: If the package has binaries, then they are in separate directories. The specifics will depend on the OS. Notice that your LoadLibrary error occurred when it attempted to find the dll in ...rJava/libs/x64/... On my MacOS system the ...rJava/libs/...` folder has 3 subdirectories: i386, ppc, and x86_64. (The ppc files are obviously useless baggage.)

from the terminal u can simply say

expoort FLASK_APP=app_name.py
export FLASK_ENV=development
flask run

or in ur file

if __name__ == "__main__":
    app.run(debug=True)

You can do:

int[] data = {10,20,30,40,50,60,71,80,90,91};

private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
    {
        MessageBox.Show("closing");
    }

Alternatively, create a figure() object using the figsize argument and then use add_subplot to add your subplots. E.g.

import matplotlib.pyplot as plt
import numpy as np

f = plt.figure(figsize=(10,3))
ax = f.add_subplot(121)
ax2 = f.add_subplot(122)
x = np.linspace(0,4,1000)
ax.plot(x, np.sin(x))
ax2.plot(x, np.cos(x), 'r:')

Benefits of this method are that the syntax is closer to calls of subplot() instead of subplots(). E.g. subplots doesn't seem to support using a GridSpec for controlling the spacing of the subplots, but both subplot() and add_subplot() do.

You can use this:

<div @click="f1(), f2()"></div> 

Either you can change the button type to submit

<button type="submit"  onclick="submitform()" id="save">Save</button>

Or you can hide the submit button, keep another button with type="button" and have click event for that button

<form>
    <button style="display: none;" type="submit" >Hidden button</button>
    <button type="button" onclick="submitForm()">Submit</button>
</form>

search ⇒ find something anywhere in the string and return a match object.

match ⇒ find something at the beginning of the string and return a match object.

The post Reset Demystified in the blog Pro Git gives a very no-brainer explanation on git reset and git checkout.

After all the helpful discussion at the top of that post, the author reduces the rules to the following simple three steps:

That is basically it. The reset command overwrites these three trees in a specific order, stopping when you tell it to.

1. Move whatever branch HEAD points to (stop if --soft)
2. THEN, make the Index look like that (stop here unless --hard)
3. THEN, make the Working Directory look like that

There are also --merge and --keep options, but I would rather keep things simpler for now - that will be for another article.

Use number formatter to format the value, as required. Please check this.

You can only return from inside a function and not from a loop.

It seems like your return should be outside the while loop, and your complete code should be inside a function.

def func():
    N = int(input("enter a positive integer:"))
    counter = 1
    while (N > 0):
        counter = counter * N
        N -= 1
    return counter  # de-indent this 4 spaces to the left.

print func()

And if those codes are not inside a function, then you don't need a return at all. Just print the value of counter outside the while loop.

pthread.h is a header for the Unix/Linux (POSIX) API for threads. A POSIX layer such as Cygwin would probably compile an app with #include <pthreads.h>.

The native Windows threading API is exposed via #include <windows.h> and it works slightly differently to Linux's threading.

Still, there's a replacement "glue" library maintained at http://sourceware.org/pthreads-win32/ ; note that it has some slight incompatibilities with MinGW/VS (e.g. see here).

git branch --set-upstream <<origin/branch>> is officially not supported anymore and is replaced by git branch --set-upstream-to <<origin/branch>>

Echo with preceding space and without newline

As stated by Pedro earlier, echo without new line and with preceding space works (provided "9" is a true [BackSpace]).

<nul set /p=.9    Hello everyone

I had some issues getting it to work in Windows 10 with the new console but managed the following way.
In CMD type:

echo .?>bs.txt

I got "?" by pressing [Alt] + [8]
(the actual symbol may vary depending upon codepage).

Then it's easy to copy the result from "bs.txt" using Notepad.exe to where it's needed.

@echo off
<nul set /p "_s=.?    Hello everyone"
echo: here

Arrays.sort(yourArray)

will do the job perfectly

Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:

type: "GET",    
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
    withCredentials: true
},
success: function (data) {
    alert(data);
});

Regular expression works too:

import re
with open("depression.txt") as f:
     l = re.split(' ', re.sub('\n',' ', f.read()))[:-1]

print (l)

['I', 'feel', 'empty', 'and', 'dead', 'inside']

var str = "texttexttext";
var arr = ["asd", "ghj", "xtte"];
for (var i = 0, len = arr.length; i < len; ++i) {
    if (str.indexOf(arr[i]) != -1) {
        // str contains arr[i]
    }
}

edit: If the order of the tests doesn't matter, you could use this (with only one loop variable):

var str = "texttexttext";
var arr = ["asd", "ghj", "xtte"];
for (var i = arr.length - 1; i >= 0; --i) {
    if (str.indexOf(arr[i]) != -1) {
        // str contains arr[i]
    }
}

If you have the text in variable foo:

if (! /^[a-zA-Z0-9]+$/.test(foo)) {
    // Validation failed
}

This will test and make sure the user has entered at least one character, and has entered only alphanumeric characters.

As already mentioned, you can get a performance increase from having your python code compiled into bytecode. This is usually handled by python itself, for imported scripts only.

Another reason you might want to compile your python code, could be to protect your intellectual property from being copied and/or modified.

You can read more about this in the Python documentation.

You can use HttpEntity to read both Body and Headers.

   @RequestMapping(value = "/restURL")
   public String serveRest(HttpEntity<String> httpEntity){
                MultiValueMap<String, String> headers = 
                httpEntity.getHeaders();
                Iterator<Map.Entry<String, List<String>>> s = 
                headers.entrySet().iterator();
                while(s.hasNext()) {
                    Map.Entry<String, List<String>> obj = s.next();
                    String key = obj.getKey();
                    List<String> value = obj.getValue();
                }
                
                String body = httpEntity.getBody();

    }

Use TimeSpan.Parse to convert the string

You can use a List-Comprehension to make it a one-liner:

[fl.readline() for i in xrange(17)]

More about list comprehension in PEP 202 and in the Python documentation.

Sometimes in Windows whitespaces in paths are not recognized correctly

If you have a path problem and path seems like

c:\Program Files\....

try changing it in an old DOS format like

"C:\Progra~1\...

You can use dir /x to check correct syntax (third column)

C:\>dir /x ... 11.01.2008 15:47 <DIR> DOCUME~1 Documents and Settings 01.12.2006 09:10 <DIR> MYPROJ~1 My Projects 21.01.2011 14:08 <DIR> PROGRA~1 Program Files ...

In my pc JAVA_HOME is (and it works)

"C:\Progra~1\Java\jdk1.8.0_121"

Tested in Windows 10

The code commented works as well, just choose which do you prefer

You want a block element that has what CSS calls shrink-to-fit width and the spec does not provide a blessed way to get such a thing. In CSS2, shrink-to-fit is not a goal, but means to deal with a situation where browser "has to" get a width out of thin air. Those situations are:

• float
• absolutely positioned element
• inline-block element
• table element

when there are no width specified. I heard they think of adding what you want in CSS3. For now, make do with one of the above.

The decision not to expose the feature directly may seem strange, but there is a good reason. It is expensive. Shrink-to-fit means formatting at least twice: you cannot start formatting an element until you know its width, and you cannot calculate the width w/o going through entire content. Plus, one does not need shrink-to-fit element as often as one may think. Why do you need extra div around your table? Maybe table caption is all you need.

No idea why the cast works, but Foo::MEMBER isn't allocated until the first time Foo is loaded, and since you're never loading it, it's never allocated. If you had a reference to a Foo somewhere, it would probably work.

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

You just also need to apply the color to 'tbody' element as that's the table body that's been causing our trouble by peeking underneath.
table, tbody, tr, th, td{ background-color: rgba(0, 0, 0, 0.0) !important; }

As mentioned in Takahiko Kawasaki's answer, java represents Unicode strings in the form of modified UTF-8 and in JVM-Spec CONSTANT_UTF8_info Structure, 2 bytes are allocated to length (and not the no. of characters of String).
To extend the answer, the ASM jvm bytecode library's putUTF8 method, contains this:

public ByteVector putUTF8(final String stringValue) {
    int charLength = stringValue.length();
    if (charLength > 65535) {   
   // If no. of characters> 65535, than however UTF-8 encoded length, wont fit in 2 bytes.
      throw new IllegalArgumentException("UTF8 string too large");
    }
    for (int i = 0; i < charLength; ++i) {
      char charValue = stringValue.charAt(i);
      if (charValue >= '\u0001' && charValue <= '\u007F') {
        // Unicode code-point encoding in utf-8 fits in 1 byte.
        currentData[currentLength++] = (byte) charValue;
      } else {
        // doesnt fit in 1 byte.
        length = currentLength;
        return encodeUtf8(stringValue, i, 65535);
      }
    }
    ...
}

But when code-point mapping > 1byte, it calls encodeUTF8 method:

final ByteVector encodeUtf8(final String stringValue, final int offset, final int maxByteLength /*= 65535 */) {
    int charLength = stringValue.length();
    int byteLength = offset;
    for (int i = offset; i < charLength; ++i) {
      char charValue = stringValue.charAt(i);
      if (charValue >= 0x0001 && charValue <= 0x007F) {
        byteLength++;
      } else if (charValue <= 0x07FF) {
        byteLength += 2;
      } else {
        byteLength += 3;
      }
    }
   ...
}

In this sense, the max string length is 65535 bytes, i.e the utf-8 encoding length. and not char count
You can find the modified-Unicode code-point range of JVM, from the above utf8 struct link.

like say a class .c1 has height:40px; how do I get rid of this height property?

Sadly, you can't. CSS doesn't have a "default" placeholder.

In that case, you would reset the property using

 height: auto;

as @Ben correctly points out, in some cases, inherit is the correct way to go, for example when resetting the text colour of an a element (that property is inherited from the parent element):

a { color: inherit }

And now the easy way

update my_table m, -- let create a temp table with populated values
    (select 1 as id, 20 as value union -- this part will be generated
     select 2 as id, 30 as value union -- using a backend code
     -- for loop 
     select N as id, X as value
        ) t
set m.value = t.value where t.id=m.id -- now update by join - quick

The original code for the Cocoa frameworks came from the NeXTSTEP libraries Foundation and AppKit (those names are still used by Apple's Cocoa frameworks), and the NextStep engineers chose to prefix their symbols with NS.

Because Objective-C is an extension of C and thus doesn't have namespaces like in C++, symbols must be prefixed with a unique prefix so that they don't collide. This is particularly important for symbols defined in a framework.

If you are writing an application, such that your code is only likely ever to use your symbols, you don't have to worry about this. But if you're writing a framework or library for others' use, you should also prefix your symbols with a unique prefix. CocoaDev has a page where many developers in the Cocoa community have listed their "chosen" prefixes. You may also find this SO discussion helpful.

If all steps (in existing answers) dont work , Just close eclipse and again open eclipse .

I wrote a mixin for some syntactic sugar ;)
Maybe someone likes this way of writing if-then-else better than using guards

depends on Less 1.7.0

https://github.com/pixelass/more-or-less/blob/master/less/fn/_if.less

Usage:

.if(isnumber(2), {
    .-then(){
        log {
            isnumber: true;
        }
    }
    .-else(){
        log {
            isnumber: false;
        }
    }
});

.if(lightness(#fff) gt (20% * 2), {
    .-then(){
        log {
            is-light: true;
        }
    }
});

using on example from above

.if(@debug, {
    .-then(){
        header {
            background-color: yellow;
            #title {

Are you sure the page you are redirecting too doesn't have a redirection within that if no session data is found? That could be your problem

Also yes always add whitespace like @Peter O suggested.

The requirement is 2 digits after decimal. There should be no limit for digits before decimal point. So, solution should be,

public class DecimalDigitsInputFilter implements InputFilter {

    Pattern mPattern;

    public DecimalDigitsInputFilter() {
        mPattern = Pattern.compile("[0-9]*+((\\.[0-9]?)?)||(\\.)?");
    }

    @Override
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
        Matcher matcher = mPattern.matcher(dest);
        if (!matcher.matches())
            return "";
        return null;
    }
}

And use it as,

mEditText.setFilters(new InputFilter[]{new DecimalDigitsInputFilter()});

Thanks to @Pinhassi for the inspiration.

Here is my function for finding multiple occurrences. Unlike the other solutions here, it supports the optional start and end parameters for slicing, just like str.index:

def all_substring_indexes(string, substring, start=0, end=None):
    result = []
    new_start = start
    while True:
        try:
            index = string.index(substring, new_start, end)
        except ValueError:
            return result
        else:
            result.append(index)
            new_start = index + len(substring)

One of many solutions is to create an @Injectable() class which holds data that you want to show in the header. Other components can also access this class and alter this data, effectively changing the header.

Another option is to set up @Input() variables and @Output() EventEmitters which you can use to alter the header data.

Edit Examples as you requested:

@Injectable()
export class HeaderService {
    private _data;
    set data(value) {
        this._data = value;
    }
    get data() {
        return this._data;
    }
}

in other component:

constructor(private headerService: HeaderService) {}

// Somewhere
this.headerService.data = 'abc';

in header component:

let headerData;

constructor(private headerService: HeaderService) {
    this.headerData = this.headerService.data;
}

I haven't actually tried this. If the get/set doesn't work you can change it to use a Subject();

// Simple Subject() example:
let subject = new Subject();
this.subject.subscribe(response => {
  console.log(response); // Logs 'hello'
});
this.subject.next('hello');

I'm posting this here, because I've spent like 3 and 4 hours on it, and I've only found answers like those one above, that say do add the executionTime, but it doesn't solve the problem in the case that you're using ASP .NET Core. For it, this would work:

At web.config file, add the requestTimeout attribute at aspNetCore node.

<system.webServer>
  <aspNetCore requestTimeout="00:10:00" ... (other configs goes here) />
</system.webServer>

In this example, I'm setting the value for 10 minutes.

The S parameter does not do anything on its own.

/S      Modifies the treatment of string after /C or /K (see below) 
/C      Carries out the command specified by string and then terminates  
/K      Carries out the command specified by string but remains  

Try something like this instead

Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)

You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.

Shell("perl a.pl c:\temp")

-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1

wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn

DIVs do not have a value property.

Technically, according to the DTDs, they shouldn't have a value attribute either, but generally you'll want to use .getAttribute() in this case:

function overlay()
{
    var cookieValue = document.getElementById('demo').getAttribute('value');
    alert(cookieValue);
}

If your code doesn't require the file to be truncated first, you can use the FileMode.OpenOrCreate to open the filestream, which will create the file if it doesn't exist or open it if it does. You can use the stream to point at the front and start overwriting the existing file?

I'm assuming your using a streams here, there are other ways to write a file.

As your question confirms, they are different: & is ONLY string concatenation, + is overloaded with both normal addition and concatenation.

In your example:

• because one of the operands to + is an integer VB attempts to convert the string to a integer, and as your string is not numeric it throws; and

• & only works with strings so the integer is converted to a string.

As mentioned above, if your data contains tab characters, commas, or newlines in your data then it's going to be very hard to export and import it with CSV. Values will overflow out of the fields and you will get errors. This problem is even worse if any of your long fields contain multi-line text with newline characters in them.

My method in these cases is to use the BCP command-line utility to export the data from SQL server, then use LOAD DATA INFILE .. INTO TABLE command in MySQL to read the data file back in. BCP is one of the oldest SQL Server command line utilities (dating back to the birth of SQL server - v6.5) but it is still around and still one of the easiest and most reliable ways to get data out.

To use this technique you need to create each destination table with the same or equivalent schema in MySQL. I do that by right clicking the Database in SQL enterprise manager, then Tasks->Generate Scripts... and create a SQL script for all the tables. You must then convert the script to MySQL compatible SQL by hand (definitely the worst part of the job) and finally run the CREATE TABLE commands on the MySQL database so you have matching tables to the SQL server versions column-wise, empty and ready for data.

Then, export the data from the MS-SQL side as follows.

bcp DatabaseName..TableName out TableName.dat -q -c -T -S ServerName -r \0 -t !\t!

(If you're using SQL Server Express, use a -S value like so: -S "ComputerName\SQLExpress")

That will create a file named TableName.dat, with fields delimited by ![tab]! and rows delimited by \0 NUL characters.

Now copy the .dat files into /tmp on the MySQL server and load on the MySQL side like so:

LOAD DATA INFILE '/tmp/TableName.dat' INTO TABLE TableName FIELDS TERMINATED BY '!\t!' LINES TERMINATED BY '\0';

Don't forget that the tables (TableName in this example) must be created already on the MySQL side.

This procedure is painfully manual when it comes to converting the SQL schema over, however it works for even the most difficult of data and because it uses flat files you never need to persuade SQL Server to talk to MySQL, or vice versa.

Since some codes gave a wrong result for Edge and Opera, I suggest to try this code:

$popularBrowsers = ["Opera","OPR/", "Edg", "Chrome", "Safari", "Firefox", "MSIE", "Trident"];

$userAgent = $_SERVER['HTTP_USER_AGENT'];
$userBrowser = 'Other less popular browsers';
foreach ($popularBrowsers as $browser) {
    if (strpos($userAgent, $browser) !== false) {
        $userBrowser = $browser;
        break;
    }
}

switch ($userBrowser) {
    case 'OPR/':
        $userBrowser = 'Opera';
        break;
    case 'MSIE':
        $userBrowser = 'Internet Explorer';
        break;

    case 'Trident':
        $userBrowser = 'Internet Explorer';
        break;

    case 'Edg':
        $userBrowser = 'Microsoft Edge';
        break;
}

echo "Your browser: " . $userBrowser;

See wp_get_post_terms(), you'd do something like so:

global $post;
$terms = wp_get_post_terms( $post->ID, 'YOUR_TAXONOMY_NAME',array('fields' => 'ids') );

print_r($terms);

This question is about whether an element exists and all answers check if it doesn't exist :) Minor difference but worth mentioning.

Based on jQuery documentation the recommended way to check for existence is

if ($( "#myDiv" ).length) {
    // element exists
}

If you prefer to check for missing element you could use either:

if (!$( "#myDiv" ).length) {
    // element doesn't exist
}

or

if (0 === $( "#myDiv" ).length) {
    // element doesn't exist
}

Note please that in the second option I've used === which is slightly faster than == and put the 0 on the left as a Yoda condition.

I know this is an old question, but I shall post my answer for posterity...

It depends on the system that you are building and the particular business rules in place.

I am building a moderate to large scale CRM in MongoDb, C# (Backend API), and Angular (Frontend web app) and found ObjectId utterly terrible for use in Angular Routing for selecting particular entities. Same with API Controller routing.

The suggestion above worked perfectly for my project.

db.contacts.insert({
 "id":db.contacts.find().Count()+1,
 "name":"John Doe",
 "emails":[
    "[email protected]",
    "[email protected]"
 ],
 "phone":"555111322",
 "status":"Active"
});

The reason it is perfect for my case, but not all cases is that as the above comment states, if you delete 3 records from the collection, you will get collisions.

My business rules state that due to our in house SLA's, we are not allowed to delete correspondence data or clients records for longer than the potential lifespan of the application I'm writing, and therefor, I simply mark records with an enum "Status" which is either "Active" or "Deleted". You can delete something from the UI, and it will say "Contact has been deleted" but all the application has done is change the status of the contact to "Deleted" and when the app calls the respository for a list of contacts, I filter out deleted records before pushing the data to the client app.

Therefore, db.collection.find().count() + 1 is a perfect solution for me...

It won't work for everyone, but if you will not be deleting data, it works fine.

YOU JUST CAN'T. There's no exact code to use for setting a forever cookie but an old trick will do, like current time + 10 years.

Just a note that any dates beyond January 2038 will doomed you for the cookies (32-bit int) will be deleted instantly. Wish for a miracle that that will be fixed in the near future. For 64-bit int, years around 2110 will be safe. As time goes by, software and hardware will change and may never adapt to older ones (the things we have now) so prepare the now for the future.

See Year 2038 problem

NSIndexPath * index = [self.menuTableView indexPathForSelectedRow];
[self.menuTableView deselectRowAtIndexPath:index animated:NO];

place this code according to your code and you will get your cell deselected.

The whole thing to em is, that the size is relative to the base. So I would say you could keep the font sizes by altering the base.

Example: If you base is 16px, and p is .75em (which is 12px) you would have to raise the base to about 20px. In this case p would then equal about 15px which is the minimum I personally require for mobile phones.

echo $a | grep -bo cat | sed 's/:.*$//'

Follow below steps:

• 1. Ensure to delete all the contents of the jar folder located in your local except the jar that you want to keep.
     For example files like .repositories, .pom, .sha1, .lastUpdated etc.
• 2. Execute mvn clean install -o command

This will help to use local repository jar files rather than connecting to any repository.

A solution using pathlib.Path, which is independent of the OS used:

import zipfile
from pathlib import Path

def zip_dir(path: Path, zip_file_path: Path):
    """Zip all contents of path to zip_file"""
    files_to_zip = [
        file for file in path.glob('*') if file.is_file()]
    with zipfile.ZipFile(
        zip_file_path, 'w', zipfile.ZIP_DEFLATED) as zip_f:
        for file in files_to_zip:
            print(file.name)
            zip_f.write(file, file.name)

current_dir = Path.cwd()  
zip_dir = current_dir / "test"
tools.zip_dir(
    zip_dir, current_dir / 'Zipped_dir.zip')

CSS Clip-Path

Using a clip-path is a new, up and coming alternative. Its starting to get supported more and more and is now becoming well documented. Since it uses SVG to create the shape, it is responsive straight out of the box.

• CanIUse
• Clip Path Generator

div {_x000D_
  width: 200px;_x000D_
  min-height: 200px;_x000D_
  -webkit-clip-path: polygon(0 0, 0 100%, 100% 100%, 100% 25%, 75% 0);_x000D_
  clip-path: polygon(0 0, 0 100%, 100% 100%, 100% 25%, 75% 0);_x000D_
  background: lightblue;_x000D_
}

<div>_x000D_
  <p>Some Text</p>_x000D_
</div>

CSS Transform

I have an alternative to web-tiki's transform answer.

body {_x000D_
  background: lightgreen;_x000D_
}_x000D_
div {_x000D_
  width: 200px;_x000D_

  position: relative;_x000D_
  overflow: hidden;_x000D_
}_x000D_
div.bg {_x000D_
  width: 200%;_x000D_

<div>_x000D_
  <div class="bg"></div>_x000D_
  <p>Some Text</p>_x000D_

I had a similar thing to work on, and this is how I did it.

import os

rootdir = os.getcwd()

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        #print os.path.join(subdir, file)
        filepath = subdir + os.sep + file

        if filepath.endswith(".html"):
            print (filepath)

Hope this helps.

from itertools import count, izip

def enumerate(L, n=0):
    return izip( count(n), L)

# if 2.5 has no count
def count(n=0):
    while True:
        yield n
        n+=1

Now h = list(enumerate(xrange(2000, 2005), 1)) works.

To declare a string literal as an output column, leave the Table off and just use Test. It doesn't need to be associated with a table among your joins, since it will be accessed only by its column alias. When using a metadata function like getColumnMeta(), the table name will be an empty string because it isn't associated with a table.

SELECT
  `field1`, 
  `field2`, 
  'Test' AS `field3` 
FROM `Test`;

Note: I'm using single quotes above. MySQL is usually configured to honor double quotes for strings, but single quotes are more widely portable among RDBMS.

If you must have a table alias name with the literal value, you need to wrap it in a subquery with the same name as the table you want to use:

SELECT
  field1,
  field2,
  field3
FROM 
  /* subquery wraps all fields to put the literal inside a table */
  (SELECT field1, field2, 'Test' AS field3 FROM Test) AS Test

Now field3 will come in the output as Test.field3.

A clean way of deep copying objects having nested objects inside is by using lodash's cloneDeep method.

For Angular, you can do it like this:

Install lodash with yarn add lodash or npm install lodash.

In your component, import cloneDeep and use it:

import * as cloneDeep from 'lodash/cloneDeep';
...
clonedObject = cloneDeep(originalObject);

It's only 18kb added to your build, well worth for the benefits.

I've also written an article here, if you need more insight on why using lodash's cloneDeep.

Yet Another Option:

>>> [re.split(r'(\d+)', s) for s in ('foofo21', 'bar432', 'foobar12345')]
[['foofo', '21', ''], ['bar', '432', ''], ['foobar', '12345', '']]

you can also override ToString() if your list item have more than one string

public class ListItem
{

    public string string1 { get; set; }

    public string string2 { get; set; }

    public string string3 { get; set; }

    public override string ToString()
    {
        return string.Join(
        ","
        , string1 
        , string2 
        , string3);

    }

}

to get csv string:

ListItem item = new ListItem();
item.string1 = "string1";
item.string2 = "string2";
item.string3 = "string3";

List<ListItem> list = new List<ListItem>();
list.Add(item);

string strinCSV = (string.Join("\n", list.Select(x => x.ToString()).ToArray()));

It is possible to horisontally center the div this way:

html:

<div class="container">
    <div class="inner">content</div>
</div>

css:

.container {
    left: 0;
    right: 0;
    bottom: 0; /* or top: 0, or any needed value */
    position: fixed;
    z-index: 1000; /* or even higher to prevent guarantee overlapping */
}

.inner {
    max-width: 600px; /* just for example */
    margin: 0 auto;
}

Using this way you will have always your inner block centered, in addition it can be easily turned to true responsive (in the example it will be just fluid on smaller screens), therefore no limitation in as in the question example and in the chosen answer.

Scikit-Learn is just telling you it doesn't recognise the argument "stratify", not that you're using it incorrectly. This is because the parameter was added in version 0.17 as indicated in the documentation you quoted.

So you just need to update Scikit-Learn.

Justin's answer did not work for me (Chromium 18, Firefox 43.0.1). jQuery's .focus() creates visual highlight, but text cursor does not appear in the field (jquery 3.1.0).

Inspired by https://www.sitepoint.com/jqueryhtml5-input-focus-cursor-positions/ , I added autofocus attribute to the input field and voila!

function addfield() {
    n=$('table tr').length;
    $('table').append('<tr><td><input name=field'+n+' autofocus></td><td><input name=value'+n+'></td></tr>');
    $('input[name="aa"'+n+']').focus();
}

AS Scott mentioned here http://weblogs.asp.net/scottgu/archive/2010/09/30/asp-net-security-fix-now-on-windows-update.aspx After windows installed security update for .net framework, you will meet this problem. just modify the configuration section in your web.config file and switch to a different cookie name.

It also important taking in account how you access the Arguments in the code of the application.

In my c# application I used the ServiceBase class:

 class MyService : ServiceBase
{

    protected override void OnStart(string[] args)
    {
       }
 }

I registered my service using

sc create myService binpath= "MeyService.exe arg1 arg2"

But I couldn't access the arguments through the args variable when I run it as a service.

The MSDN documentation suggests not using the Main method to retrieve the binPath or ImagePath arguments. Instead it suggests placing your logic in the OnStart method and then using (C#) Environment.GetCommandLineArgs();.

To access the first arguments arg1 I need to do like this:

class MyService : ServiceBase
 {

    protected override void OnStart(string[] args)
    {

                log.Info("arg1 == "+Environment.GetCommandLineArgs()[1]);

       }
 }

this would print

       arg1 == arg1

  DefaultTreeModel treeModel;

  public TestTree( ) {
    super("Tree Test Example");
    setSize(400, 300);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
  }

  public void init( ) {
    // Build up a bunch of TreeNodes. We use DefaultMutableTreeNode because the
    // DefaultTreeModel can use it to build a complete tree.
    DefaultMutableTreeNode root = new DefaultMutableTreeNode("Root");
    DefaultMutableTreeNode subroot = new DefaultMutableTreeNode("SubRoot");
    DefaultMutableTreeNode leaf1 = new DefaultMutableTreeNode("Leaf 1");
    DefaultMutableTreeNode leaf2 = new DefaultMutableTreeNode("Leaf 2");

    // Build our tree model starting at the root node, and then make a JTree out
    // of it.
    treeModel = new DefaultTreeModel(root);
    tree = new JTree(treeModel);

    // Build the tree up from the nodes we created.
    treeModel.insertNodeInto(subroot, root, 0);
    // Or, more succinctly:
    subroot.add(leaf1);
    root.add(leaf2);

    // Display it.
    getContentPane( ).add(tree, BorderLayout.CENTER);
  }

  public static void main(String args[]) {
    TestTree tt = new TestTree( );
    tt.init( );
    tt.setVisible(true);
  }
}

I could not restart IIexpress. This is the solution that worked for me

1. Cleaned the build
2. Rebuild

Go to this key on Registry Editor (Run | Regedit) HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

change key Cache to something like C:\Windows\Temp

My similar problem was solved like this.

I think the fastest and simplest way would be to use an XmlReader, this will not require any recursion and minimal memory foot print.

Here is a simple example, for compactness I just used a simple string of course you can use a stream from a file etc.

  string xml = @"
    <parent>
      <child>
        <nested />
      </child>
      <child>
        <other>
        </other>
      </child>
    </parent>
    ";

  XmlReader rdr = XmlReader.Create(new System.IO.StringReader(xml));
  while (rdr.Read())
  {
    if (rdr.NodeType == XmlNodeType.Element)
    {
      Console.WriteLine(rdr.LocalName);
    }
  }

The result of the above will be

parent
child
nested
child
other

A list of all the elements in the XML document.

A line feed means moving one line forward. The code is \n.
A carriage return means moving the cursor to the beginning of the line. The code is \r.

Windows editors often still use the combination of both as \r\n in text files. Unix uses mostly only the \n.

The separation comes from typewriter times, when you turned the wheel to move the paper to change the line and moved the carriage to restart typing on the beginning of a line. This was two steps.

eburgos, I've modified your code slightly because when you have multiple datatables in your dataset it was just overwriting them in the spreadsheet so you were only left with one sheet in the workbook. I basically just moved the part where the workbook is created out of the loop. Here is the updated code.

private void ExportDSToExcel(DataSet ds, string destination)
{
    using (var workbook = SpreadsheetDocument.Create(destination, DocumentFormat.OpenXml.SpreadsheetDocumentType.Workbook))
    {
        var workbookPart = workbook.AddWorkbookPart();
        workbook.WorkbookPart.Workbook = new DocumentFormat.OpenXml.Spreadsheet.Workbook();
        workbook.WorkbookPart.Workbook.Sheets = new DocumentFormat.OpenXml.Spreadsheet.Sheets();

        uint sheetId = 1;

        foreach (DataTable table in ds.Tables)
        {
            var sheetPart = workbook.WorkbookPart.AddNewPart<WorksheetPart>();
            var sheetData = new DocumentFormat.OpenXml.Spreadsheet.SheetData();
            sheetPart.Worksheet = new DocumentFormat.OpenXml.Spreadsheet.Worksheet(sheetData);                

            DocumentFormat.OpenXml.Spreadsheet.Sheets sheets = workbook.WorkbookPart.Workbook.GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>();
            string relationshipId = workbook.WorkbookPart.GetIdOfPart(sheetPart);

            if (sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Count() > 0)
            {
                sheetId =
                    sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Select(s => s.SheetId.Value).Max() + 1;
            }

            DocumentFormat.OpenXml.Spreadsheet.Sheet sheet = new DocumentFormat.OpenXml.Spreadsheet.Sheet() { Id = relationshipId, SheetId = sheetId, Name = table.TableName };
            sheets.Append(sheet);

            DocumentFormat.OpenXml.Spreadsheet.Row headerRow = new DocumentFormat.OpenXml.Spreadsheet.Row();

            List<String> columns = new List<string>();
            foreach (DataColumn column in table.Columns)
            {
                columns.Add(column.ColumnName);

                DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell();
                cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String;
                cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(column.ColumnName);
                headerRow.AppendChild(cell);
            }

            sheetData.AppendChild(headerRow);

            foreach (DataRow dsrow in table.Rows)
            {
                DocumentFormat.OpenXml.Spreadsheet.Row newRow = new DocumentFormat.OpenXml.Spreadsheet.Row();
                foreach (String col in columns)
                {
                    DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell();
                    cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String;
                    cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(dsrow[col].ToString()); //
                    newRow.AppendChild(cell);
                }

                sheetData.AppendChild(newRow);
            }
        }
    }
}

See the below code (taken from this post)

Put this code in a Module in VBA (Developer Tab -> Visual Basic)

Dim TimerActive As Boolean
Sub StartTimer()
    Start_Timer
End Sub
Private Sub Start_Timer()
    TimerActive = True
    Application.OnTime Now() + TimeValue("00:01:00"), "Timer"
End Sub
Private Sub Stop_Timer()
    TimerActive = False
End Sub
Private Sub Timer()
    If TimerActive Then
        ActiveSheet.Cells(1, 1).Value = Time
        Application.OnTime Now() + TimeValue("00:01:00"), "Timer"
    End If
End Sub

You can invoke the "StartTimer" function when the workbook opens and have it repeat every minute by adding the below code to your workbooks Visual Basic "This.Workbook" class in the Visual Basic editor.

Private Sub Workbook_Open()
    Module1.StartTimer
End Sub

Now, every time 1 minute passes the Timer procedure will be invoked, and set cell A1 equal to the current time.

I was uninstalled compass 1.0.1 and install compass 0.12.7, this fix problem for me

$ sudo gem uninstall compass

If the table has an ID:

const tableObject = document.getElementById(tableId);
const rowCount = tableObject[1].childElementCount;

If the table has a Class:

const tableObject = document.getElementsByClassName(tableClass);
const rowCount = tableObject[1].childElementCount;

If the table has a Name:

const tableObject = document.getElementsByTagName('table');
const rowCount = tableObject[1].childElementCount;

Note: index 1 represents <tbody> tag

For anyone looking for a clean way to encode a POST request in Swift 5.

You don’t need to deal with manually adding percent encoding. Use URLComponents to create a GET request URL. Then use query property of that URL to get properly percent escaped query string.

let url = URL(string: "https://example.com")!
var components = URLComponents(url: url, resolvingAgainstBaseURL: false)!

components.queryItems = [
    URLQueryItem(name: "key1", value: "NeedToEscape=And&"),
    URLQueryItem(name: "key2", value: "vålüé")
]

let query = components.url!.query

The query will be a properly escaped string:

key1=NeedToEscape%3DAnd%26&key2=v%C3%A5l%C3%BC%C3%A9

Now you can create a request and use the query as HTTPBody:

var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = Data(query.utf8)

Now you can send the request.

Your problem are the cr (carriage return)

http://jsfiddle.net/NT9KB/210/

you can use:

document.getElementById("img").src = "data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=="

More info... Some times .swp files might be holded by vm that was running in backgroung. You may see permission denied message when try to delete the files.

Well, note that the request contains binary data, so I'm not posting the request as such - instead, I've converted every non-printable-ascii character into a dot (".").

public interface IContainsMyModel
{
    ViewModel Model { get; }
}

public class ViewModel : IContainsMyModel
{
    public string MyProperty { set; get; }
    public ViewModel Model { get { return this; } }
}

public class Composition : IContainsMyModel
{
    public ViewModel ViewModel { get; set; }
}

Use IContainsMyModel in your layout.

Solved. Interfaces rule.

You can use "wildcards" with MATCH so assuming "ASDFGHJK" in H1 as per Peter's reply you can use this regular formula

=INDEX(G:G,MATCH("*"&H1&"*",G:G,0)+3)

MATCH can only reference a single column or row so if you want to search 6 columns you either have to set up a formula with 6 MATCH functions or change to another approach - try this "array formula", assuming search data in A2:G100

=INDIRECT("R"&REPLACE(TEXT(MIN(IF(ISNUMBER(SEARCH(H1,A2:G100)),(ROW(A2:G100)+3)*1000+COLUMN(A2:G100))),"000000"),4,0,"C"),FALSE)

Now docker-compose supports variable substitution.

Compose uses the variable values from the shell environment in which docker-compose is run. For example, suppose the shell contains POSTGRES_VERSION=9.3 and you supply this configuration in your docker-compose.yml file:

db:
  image: "postgres:${POSTGRES_VERSION}"

When you run docker-compose up with this configuration, Compose looks for the POSTGRES_VERSION environment variable in the shell and substitutes its value in. For this example, Compose resolves the image to postgres:9.3 before running the configuration.

A useful hack for me is to set the (selects) display to inline-flex. Cuts the arrow right out of my select button. Without all of the added code.

If a website's directory does NOT have an "index...." file, AND .htaccess has NOT been used to block access to the directory itself, then Apache will create an "index of" page for that directory. You can save that page, and its icons, using "Save page as..." along with the "Web page, complete" option (Firefox example). If you own the website, temporarily rename any "index...." file, and reference the directory locally. Then restore your "index...." file.

You can use the Mock.call_args_list attribute to compare parameters to previous method calls. That in conjunction with Mock.call_count attribute should give you full control.

There are some guys at Mozilla working on implementing a PDF reader using HTML5 and JavaScript. It is called pdf.js and one of the developers just made an interesting blog post about the project.

There might be a chance that you have install node.js while your visual studio code was open. Once node.js is install successfully, Simply close the VS Code and Start it again. It will work. Thank you

The await inside your asynchronous method is trying to come back to the UI thread.

Since the UI thread is busy waiting for the entire task to complete, you have a deadlock.

Moving the async call to Task.Run() solves the issue.
Because the async call is now running on a thread pool thread, it doesn't try to come back to the UI thread, and everything therefore works.

Alternatively, you could call StartAsTask().ConfigureAwait(false) before awaiting the inner operation to make it come back to the thread pool rather than the UI thread, avoiding the deadlock entirely.

In case you want a secondary splash screen (after the native one), here is a simple example that works:

class SplashPage extends StatelessWidget {
  SplashPage(BuildContext context) {
    Future.delayed(const Duration(seconds: 3), () {
      // Navigate here to next screen
    });
  }

  @override
  Widget build(BuildContext context) {
    return Text('Splash screen here');
  }
}

To call the method, you need to qualify function with self.. In addition to that, if you want to pass a filename, add a filename parameter (or other name you want).

class MyHandler(FileSystemEventHandler):

    def on_any_event(self, event):
        srcpath = event.src_path
        print (srcpath, 'has been ',event.event_type)
        print (datetime.datetime.now())
        filename = srcpath[12:]
        self.dropbox_fn(filename) # <----

    def dropbox_fn(self, filename):  # <-----
        print('In dropbox_fn:', filename)

This is surely Eclipse related issue. The thing which worked for me is creating a new server in eclipse server tab. Then run your application in this new server, it should work.

// Set flash data 
$this->session->set_flashdata('message_name', 'This is my message');
// After that you need to used redirect function instead of load view such as 
redirect("admin/signup");

// Get Flash data on view 
$this->session->flashdata('message_name');

please go to .env file and change the value of AWS_DEFAULT_REGION to special area u want to...

AWS_DEFAULT_REGION = Asia/Dhaka

I would suggest Travis for Open source project. It's just simple to configure and use.

Simple steps to setup:

1. Should have GITHUB account and register in Travis CI website using your GITHUB account.
2. Add .travis.yml file in root of your project. Add Travis as service in your repository settings page.

Now every time you commit into your repository Travis will build your project. You can follow simple steps to get started with Travis CI.

The reason why @Resource(name = "{your child class name}") works but @Autowired sometimes don't work is because of the difference of their Matching sequence

Matching sequence of @Autowire
Type, Qualifier, Name

Matching sequence of @Resource
Name, Type, Qualifier

The more detail explanation can be found here:
Inject and Resource and Autowired annotations

In this case, different child class inherited from the parent class or interface confuses @Autowire, because they are from same type; As @Resource use Name as first matching priority , it works.

Be careful of a global temp table solution as this may fail if two users use the same routine at the same time as a global temp table can be seen by all users...

You should try this

import java.util.Scanner;

public class Time_converter {

    public static void main(String[] args) {

        Scanner input = new Scanner (System.in);
        int seconds;
        int minutes ;
        int hours;
        System.out.print("Enter the number of seconds : ");
        seconds = input.nextInt();
        hours = seconds / 3600;
        minutes = (seconds%3600)/60;
        int seconds_output = (seconds% 3600)%60;


        System.out.println("The time entered in hours,minutes and seconds is:");
        System.out.println(hours  + " hours :" + minutes + " minutes:" + seconds_output +" seconds"); 
    }

}

You should be able to declare a cursor to be a bind variable (called parameters in other DBMS')

like Vincent wrote, you can do something like this:

begin
  open :yourCursor
    for 'SELECT "'|| :someField ||'" from yourTable where x = :y'
      using :someFilterValue;
end;

You'd have to bind 3 vars to that script. An input string for "someField", a value for "someFilterValue" and an cursor for "yourCursor" which has to be declared as output var.

Unfortunately, I have no idea how you'd do that from C++. (One could say fortunately for me, though. ;-) )

Depending on which access library you use, it might be a royal pain or straight forward.

Here is an example that's working for me with MVC and Javascript in the Razor. The first function calls an action via ajax on my controller and passes two parameters.

        function redirectToAction(var1, var2)
        {
            try{

                var url = '../actionnameinsamecontroller/' + routeId;

                $.ajax({
                    type: "GET",
                    url: url,
                    data: { param1: var1, param2: var2 },
                    dataType: 'html',
                    success: function(){
                    },
                    error: function(xhr, ajaxOptions, thrownError){
                        alert(error);
                    }
                });

            }
            catch(err)
            {
                alert(err.message);
            }
        }

Use the ajaxStart to start your progress bar code.

           $(document).ajaxStart(function(){
            try
            {
                // showing a modal
                $("#progressDialog").modal();

                var i = 0;
                var timeout = 750;

                (function progressbar()
                {
                    i++;
                    if(i < 1000)
                    {
                        // some code to make the progress bar move in a loop with a timeout to 
                        // control the speed of the bar
                        iterateProgressBar();
                        setTimeout(progressbar, timeout);
                    }
                }
                )();
            }
            catch(err)
            {
                alert(err.message);
            }
        });

When the process completes close the progress bar

        $(document).ajaxStop(function(){
            // hide the progress bar
            $("#progressDialog").modal('hide');
        });
