Before Java 7:

 BufferedReader br = new BufferedReader(new FileReader("foo.txt"));
 String line;
 while ((line = br.readLine()) != null) {
   System.out.println(line);
 }

• add exception handling
• add closing the stream

Since Java 7, there is no need to close the stream, because it implements autocloseable

try (BufferedReader br = new BufferedReader(new FileReader("foo.txt"))) {
   String line;
   while ((line = br.readLine()) != null) {
       System.out.println(line);
   }
}

I created this test case: http://jsfiddle.net/ccQnK/1/ , I used the Javascript replace function with regular expressions to get the results that you want.

$(document).ready(function() {
    var myContent = '<div id="test">Hello <span>world!</span></div>';
    alert(myContent.replace(/(<([^>]+)>)/ig,""));
});

Even though you've accepted an answer, I want to post this method. I use jQuery to center it vertically instead of css (although both of these methods work). Here is a fiddle, and I'll post the code here anyways.

HTML:

<h1>Hello world!</h1>

Javascript (jQuery):

$(document).ready(function(){
  $('h1').css({ 'width':'100%', 'text-align':'center' });
  var h1 = $('h1').height();
  var h = h1/2;
  var w1 = $(window).height();
  var w = w1/2;
  var m = w - h
  $('h1').css("margin-top",m + "px")
});

This takes the height of the viewport, divides it by two, subtracts half the height of the h1, and sets that number to the margin-top of the h1. The beauty of this method is that it works on multiple-line h1s.

EDIT: I modified it so that it centered it every time the window is resized.

Do lines in the file have whitespace characters?

If so then

grep "\S" file.txt

Otherwise

grep . file.txt

Instead of using regex for spliting the text into sentences, you can also use nltk library.

>>> from nltk import tokenize
>>> p = "Good morning Dr. Adams. The patient is waiting for you in room number 3."

>>> tokenize.sent_tokenize(p)
['Good morning Dr. Adams.', 'The patient is waiting for you in room number 3.']

PHP iconv()

iconv("UTF-8", "ISO-8859-15", $input);

The copy buffer can't be accessed outside of nano, and nowhere I found any buffer file to read.

Here is a dirty alternative when in full NOX: Printing a given file line in the bash history.

So the given line is available as a command with the UP key.

sed "LINEq;d" FILENAME >> ~/.bash_history

Example:

sed "342q;d" doc.txt >> ~/.bash_history

Then to reload the history into the current session:

history -n

Or to make history reloading automatic at new prompts, paste this in .bash_profile:

PROMPT_COMMAND='history -n ; $PROMPT_COMMAND'

Note for AZERTY keyboards and very probably others layouts that require SHIFT for printing numbers from the top keys.

To toggle nano text selection (Mark Set/Unset) the shortcut is:

CTRL + SHIFT + 2

Or

ALT + a

You can then select the text with the arrows keys.

All of the others shortcuts works fine as the documentation:

CTRL + k or F9 to cut.

CTRL + u or F10 to paste.

Your hack of decrementing the count at the end is exactly that -- a hack.

Far better to write your loop correctly in the first place, so it doesn't count the last line twice.

int main() { 
    int number_of_lines = 0;
    std::string line;
    std::ifstream myfile("textexample.txt");

    while (std::getline(myfile, line))
        ++number_of_lines;
    std::cout << "Number of lines in text file: " << number_of_lines;
    return 0;
}

Personally, I think in this case, C-style code is perfectly acceptable:

int main() {
    unsigned int number_of_lines = 0;
    FILE *infile = fopen("textexample.txt", "r");
    int ch;

    while (EOF != (ch=getc(infile)))
        if ('\n' == ch)
            ++number_of_lines;
    printf("%u\n", number_of_lines);
    return 0;
}

Edit: Of course, C++ will also let you do something a bit similar:

int main() {
    std::ifstream myfile("textexample.txt");

    // new lines will be skipped unless we stop it from happening:    
    myfile.unsetf(std::ios_base::skipws);

    // count the newlines with an algorithm specialized for counting:
    unsigned line_count = std::count(
        std::istream_iterator<char>(myfile),
        std::istream_iterator<char>(), 
        '\n');

    std::cout << "Lines: " << line_count << "\n";
    return 0;
}

I found two other solutions if you know the line number but nothing else (no grep possible):

Assuming you need lines 20 to 40,

sed -n '20,40p;41q' file_name

or

awk 'FNR>=20 && FNR<=40' file_name

I suggest you check out chunked and disk.frame. They both have functions for reading in CSVs chunk-by-chunk.

In particular, disk.frame::csv_to_disk.frame may be the function you are after?

Things seems a little confused in the code in your question, so I am going to give you an example of what I think you are try to do.

First considerations are about mixing HTML, Javascript and CSS:

Why is using onClick() in HTML a bad practice?

Unobtrusive Javascript

Inline Styles vs Classes

I will be removing inline content and splitting these into their appropriate files.

Next, I am going to go with the "click" event and displose of the "change" event, as it is not clear that you want or need both.

Your function changeBackground sets both the backround color and the text color to the same value (your text will not be seen), so I am caching the color value as we don't need to look it up in the DOM twice.

CSS

#TheForm {
    margin-left: 396px;
}
#submitColor {
    margin-left: 48px;
    margin-top: 5px;
}

HTML

<form id="TheForm">
    <input id="color" type="text" />
    <br/>
    <input id="submitColor" value="Submit" type="button" />
</form>
<span id="coltext">This text should have the same color as you put in the text box</span>

Javascript

function changeBackground() {
    var color = document.getElementById("color").value; // cached

    // The working function for changing background color.
    document.bgColor = color;

    // The code I'd like to use for changing the text simultaneously - however it does not work.
    document.getElementById("coltext").style.color = color;
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

Color Values

CSS colors are defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF).

Hex values are written as 3 double digit numbers, starting with a # sign.

Update: as pointed out by @Ian

Hex can be either 3 or 6 characters long

Source: W3C

Numerical color values

The format of an RGB value in hexadecimal notation is a ‘#’ immediately followed by either three or six hexadecimal characters. The three-digit RGB notation (#rgb) is converted into six-digit form (#rrggbb) by replicating digits, not by adding zeros. For example, #fb0 expands to #ffbb00. This ensures that white (#ffffff) can be specified with the short notation (#fff) and removes any dependencies on the color depth of the display.

Here is an alternative function that will check that your input is a valid CSS Hex Color, it will set the text color only or throw an alert if it is not valid.

For regex testing, I will use this pattern

/^#(?:[0-9a-f]{3}){1,2}$/i

but if you were regex matching and wanted to break the numbers into groups then you would require a different pattern

function changeBackground() {
    var color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i;

    if (rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;
    } else {
        alert("Invalid CSS Hex Color");
    }
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

On jsfiddle

Here is a further modification that will allow colours by name along with by hex.

function changeBackground() {
    var names = ["AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond", "Blue", "BlueViolet", "Brown", "BurlyWood", "CadetBlue", "Chartreuse", "Chocolate", "Coral", "CornflowerBlue", "Cornsilk", "Crimson", "Cyan", "DarkBlue", "DarkCyan", "DarkGoldenRod", "DarkGray", "DarkGrey", "DarkGreen", "DarkKhaki", "DarkMagenta", "DarkOliveGreen", "Darkorange", "DarkOrchid", "DarkRed", "DarkSalmon", "DarkSeaGreen", "DarkSlateBlue", "DarkSlateGray", "DarkSlateGrey", "DarkTurquoise", "DarkViolet", "DeepPink", "DeepSkyBlue", "DimGray", "DimGrey", "DodgerBlue", "FireBrick", "FloralWhite", "ForestGreen", "Fuchsia", "Gainsboro", "GhostWhite", "Gold", "GoldenRod", "Gray", "Grey", "Green", "GreenYellow", "HoneyDew", "HotPink", "IndianRed", "Indigo", "Ivory", "Khaki", "Lavender", "LavenderBlush", "LawnGreen", "LemonChiffon", "LightBlue", "LightCoral", "LightCyan", "LightGoldenRodYellow", "LightGray", "LightGrey", "LightGreen", "LightPink", "LightSalmon", "LightSeaGreen", "LightSkyBlue", "LightSlateGray", "LightSlateGrey", "LightSteelBlue", "LightYellow", "Lime", "LimeGreen", "Linen", "Magenta", "Maroon", "MediumAquaMarine", "MediumBlue", "MediumOrchid", "MediumPurple", "MediumSeaGreen", "MediumSlateBlue", "MediumSpringGreen", "MediumTurquoise", "MediumVioletRed", "MidnightBlue", "MintCream", "MistyRose", "Moccasin", "NavajoWhite", "Navy", "OldLace", "Olive", "OliveDrab", "Orange", "OrangeRed", "Orchid", "PaleGoldenRod", "PaleGreen", "PaleTurquoise", "PaleVioletRed", "PapayaWhip", "PeachPuff", "Peru", "Pink", "Plum", "PowderBlue", "Purple", "Red", "RosyBrown", "RoyalBlue", "SaddleBrown", "Salmon", "SandyBrown", "SeaGreen", "SeaShell", "Sienna", "Silver", "SkyBlue", "SlateBlue", "SlateGray", "SlateGrey", "Snow", "SpringGreen", "SteelBlue", "Tan", "Teal", "Thistle", "Tomato", "Turquoise", "Violet", "Wheat", "White", "WhiteSmoke", "Yellow", "YellowGreen"],
        color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i,
        formattedName = color.charAt(0).toUpperCase() + color.slice(1).toLowerCase();

    if (names.indexOf(formattedName) !== -1 || rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;

Try regular expressions. You can find a certain pattern in your text and replace it with something that you want. I can't give you the exact code right now but you can test out your expressions using this.

If you are using numpy, printing a single (or multiply) strings to a file can be done with just one line:

numpy.savetxt('Output.txt', ["Purchase Amount: %s" % TotalAmount], fmt='%s')

How about using a simple loop to count the occurrences of number of spaces!?

txt = "Just an example here move along" _x000D_
count = 1_x000D_
for i in txt:_x000D_
if i == " ":_x000D_
   count += 1_x000D_
print(count)

Simply write to file string.Empty, when append is set to false in StreamWriter. I think this one is easiest to understand for beginner.

private void ClearFile()
{
    if (!File.Exists("TextFile.txt"))
        File.Create("TextFile.txt");

    TextWriter tw = new StreamWriter("TextFile.txt", false);
    tw.Write(string.Empty);
    tw.Close();
}

In JSX/ React prevent text from wrapping

<div style={{ whiteSpace: "nowrap", overflow: "hidden" }}>
   Text that will never wrap
</div>

word-wrap: break-word

But it's CSS3 - http://www.css3.com/css-word-wrap/.

copy the column paste it into notepad copy it again paste special as Text

if you need more speed and less accuracy then you could use raw lxml.

import lxml.html as lh
from lxml.html.clean import clean_html

def lxml_to_text(html):
    doc = lh.fromstring(html)
    doc = clean_html(doc)
    return doc.text_content()

Pure and simple, jar-friendly, Java 8+ solution

This simple method below will do just fine if you're using Java 8 or greater:

/**
 * Reads given resource file as a string.
 *
 * @param fileName path to the resource file
 * @return the file's contents
 * @throws IOException if read fails for any reason
 */
static String getResourceFileAsString(String fileName) throws IOException {
    ClassLoader classLoader = ClassLoader.getSystemClassLoader();
    try (InputStream is = classLoader.getResourceAsStream(fileName)) {
        if (is == null) return null;
        try (InputStreamReader isr = new InputStreamReader(is);
             BufferedReader reader = new BufferedReader(isr)) {
            return reader.lines().collect(Collectors.joining(System.lineSeparator()));
        }
    }
}

And it also works with resources in jar files.

About text encoding: InputStreamReader will use the default system charset in case you don't specify one. You may want to specify it yourself to avoid decoding problems, like this:

new InputStreamReader(isr, StandardCharsets.UTF_8);

Avoid unnecessary dependencies

Always prefer not depending on big, fat libraries. Unless you are already using Guava or Apache Commons IO for other tasks, adding those libraries to your project just to be able to read from a file seems a bit too much.

"Simple" method? You must be kidding me

I understand that pure Java does not do a good job when it comes to doing simple tasks like this. For instance, this is how we read from a file in Node.js:

const fs = require("fs");
const contents = fs.readFileSync("some-file.txt", "utf-8");

Simple and easy to read (although people still like to rely on many dependencies anyway, mostly due to ignorance). Or in Python:

with open('some-file.txt', 'r') as f:
    content = f.read()

It's sad, but it's still simple for Java's standards and all you have to do is copy the method above to your project and use it. I don't even ask you to understand what is going on in there, because it really doesn't matter to anyone. It just works, period :-)

You could try something like:

char ch;
fstream fin("file", fstream::in);
while (fin >> noskipws >> ch) {
    cout << ch; // Or whatever
}

You can use vertical-align and floating.

In most cases you want to vertical-align: middle, the image.

Here is a test: http://www.w3schools.com/cssref/tryit.asp?filename=trycss_vertical-align

vertical-align: baseline|length|sub|super|top|text-top|middle|bottom|text-bottom|initial|inherit;

For middle, the definition is: The element is placed in the middle of the parent element.

So you might want to apply that to all elements within the element.

Place the following in your jQuery mouseover event handler:

$(this).css('color', 'red');

To set both color and size at the same time:

$(this).css({ 'color': 'red', 'font-size': '150%' });

You can set any CSS attribute using the .css() jQuery function.

You need to define the button text and have valid HTML for the button. I would also suggest using .on for the click handler of the button

$(function () {_x000D_
  $('#Add').on('click', function () {_x000D_
    $('<p>Text</p>').appendTo('#Content');_x000D_
  });_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<div id="Content">_x000D_
    <button id="Add">Add Text</button>_x000D_
</div>

Also I would make sure the jquery is at the bottom of the page just before the closing </body> tag. Doing so will make it so you do not have to have the whole thing wrapped in $(function but I would still do that. Having your javascript load at the end of the page makes it so the rest of the page loads incase there is a slow down in your javascript somewhere.

Additionally to overflow:hidden, use

white-space:nowrap;

If you want some space at left and right of input view, you can add some padding like

private fun showAlertWithTextInputLayout(context: Context) {
    val textInputLayout = TextInputLayout(context)
    textInputLayout.setPadding(
        resources.getDimensionPixelOffset(R.dimen.dp_19), // if you look at android alert_dialog.xml, you will see the message textview have margin 14dp and padding 5dp. This is the reason why I use 19 here
        0,
        resources.getDimensionPixelOffset(R.dimen.dp_19),
        0
    )
    val input = EditText(context)
    textInputLayout.hint = "Email"
    textInputLayout.addView(input)

    val alert = AlertDialog.Builder(context)
        .setTitle("Reset Password")
        .setView(textInputLayout)
        .setMessage("Please enter your email address")
        .setPositiveButton("Submit") { dialog, _ ->
            // do some thing with input.text
            dialog.cancel()
        }
        .setNegativeButton("Cancel") { dialog, _ ->
            dialog.cancel()
        }.create()

    alert.show()
}

dimens.xml

<dimen name="dp_19">19dp</dimen>

Hope it help

InputStream is=getResources().openRawResource(R.raw.name);
BufferedReader reader=new BufferedReader(new InputStreamReader(is));
StringBuffer data=new StringBuffer();
String line=reader.readLine();
while(line!=null)
{

}
tvDetails.seTtext(data.toString());

• Basic Definition

TEXT and VarChar(MAX) are Non-Unicode large Variable Length character data type, which can store maximum of 2147483647 Non-Unicode characters (i.e. maximum storage capacity is: 2GB).

• Which one to Use?

As per MSDN link Microsoft is suggesting to avoid using the Text datatype and it will be removed in a future versions of Sql Server. Varchar(Max) is the suggested data type for storing the large string values instead of Text data type.

• In-Row or Out-of-Row Storage

Data of a Text type column is stored out-of-row in a separate LOB data pages. The row in the table data page will only have a 16 byte pointer to the LOB data page where the actual data is present. While Data of a Varchar(max) type column is stored in-row if it is less than or equal to 8000 byte. If Varchar(max) column value is crossing the 8000 bytes then the Varchar(max) column value is stored in a separate LOB data pages and row will only have a 16 byte pointer to the LOB data page where the actual data is present. So In-Row Varchar(Max) is good for searches and retrieval.

• Supported/Unsupported Functionalities

Some of the string functions, operators or the constructs which doesn’t work on the Text type column, but they do work on VarChar(Max) type column.

1. = Equal to Operator on VarChar(Max) type column

2. Group by clause on VarChar(Max) type column

   • System IO Considerations

As we know that the VarChar(Max) type column values are stored out-of-row only if the length of the value to be stored in it is greater than 8000 bytes or there is not enough space in the row, otherwise it will store it in-row. So if most of the values stored in the VarChar(Max) column are large and stored out-of-row, the data retrieval behavior will almost similar to the one that of the Text type column.

But if most of the values stored in VarChar(Max) type columns are small enough to store in-row. Then retrieval of the data where LOB columns are not included requires the more number of data pages to read as the LOB column value is stored in-row in the same data page where the non-LOB column values are stored. But if the select query includes LOB column then it requires less number of pages to read for the data retrieval compared to the Text type columns.

Conclusion

Use VarChar(MAX) data type rather than TEXT for good performance.

add layout_gravity and gravity with center value on TextView

<TextView
    android:text="welcome text"

The most important difference to be aware of is that with a stream opened in text mode you get newline translation on non-*nix systems (it's also used for network communications, but this isn't supported by the standard library). In *nix newline is just ASCII linefeed, \n, both for internal and external representation of text. In Windows the external representation often uses a carriage return + linefeed pair, "CRLF" (ASCII codes 13 and 10), which is converted to a single \n on input, and conversely on output.

From the C99 standard (the N869 draft document), §7.19.2/2,

A text stream is an ordered sequence of characters composed into lines, each line consisting of zero or more characters plus a terminating new-line character. Whether the last line requires a terminating new-line character is implementation-defined. Characters may have to be added, altered, or deleted on input and output to conform to differing conventions for representing text in the host environment. Thus, there need not be a one- to-one correspondence between the characters in a stream and those in the external representation. Data read in from a text stream will necessarily compare equal to the data that were earlier written out to that stream only if: the data consist only of printing characters and the control characters horizontal tab and new-line; no new-line character is immediately preceded by space characters; and the last character is a new-line character. Whether space characters that are written out immediately before a new-line character appear when read in is implementation-defined.

And in §7.19.3/2

Binary files are not truncated, except as defined in 7.19.5.3. Whether a write on a text stream causes the associated file to be truncated beyond that point is implementation- defined.

About use of fseek, in §7.19.9.2/4:

For a text stream, either offset shall be zero, or offset shall be a value returned by an earlier successful call to the ftell function on a stream associated with the same file and whence shall be SEEK_SET.

About use of ftell, in §17.19.9.4:

The ftell function obtains the current value of the file position indicator for the stream pointed to by stream. For a binary stream, the value is the number of characters from the beginning of the file. For a text stream, its file position indicator contains unspecified information, usable by the fseek function for returning the file position indicator for the stream to its position at the time of the ftell call; the difference between two such return values is not necessarily a meaningful measure of the number of characters written or read.

I think that’s the most important, but there are some more details.

The reason that this doesn't work is because the variable doesn't change with the textbox. When it initially runs the code it gets the value of the textbox, but afterwards it isn't ever called again. However, when you define the variable in the function, every time that you call the function the variable updates. Then it alerts the variable which is now equal to the textbox's input.

What you can do is the following:

.max-lines {_x000D_
  display: block;/* or inline-block */_x000D_
  text-overflow: ellipsis;_x000D_
  word-wrap: break-word;_x000D_
  overflow: hidden;_x000D_
  max-height: 3.6em;_x000D_
  line-height: 1.8em;_x000D_
}

<p class="max-lines">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc vitae leo dapibus, accumsan lorem eleifend, pharetra quam. Quisque vestibulum commodo justo, eleifend mollis enim blandit eu. Aenean hendrerit nisl et elit maximus finibus. Suspendisse scelerisque consectetur nisl mollis scelerisque.</p>

where max-height: = line-height: × <number-of-lines> in em.

This functionality can also be added using JavaScript. Carto.net has an example:

Using Node.js

sync mode:

var fs = require("fs");
var text = fs.readFileSync("./mytext.txt");
var textByLine = text.split("\n")

async mode:

var fs = require("fs");
fs.readFile("./mytext.txt", function(text){
    var textByLine = text.split("\n")
});

UPDATE

As of at least Node 6, readFileSync returns a Buffer, so it must first be converted to a string in order for split to work:

var text = fs.readFileSync("./mytext.txt").toString('utf-8');

Or

var text = fs.readFileSync("./mytext.txt", "utf-8");

vi can show all characters.

One of the disadvantages of using HTML for labels is when you need to write a localizable program (which should work in several languages). You will have issues to change just the translatable text. Or you will have to put the whole HTML code into your translations which is very awkward, I would even say absurd :)

gui_en.properties:

title.text=<html>Text color: <font color='red'>red</font></html>

gui_fr.properties:

title.text=<html>Couleur du texte: <font color='red'>rouge</font></html>

gui_ru.properties:

title.text=<html>???? ??????: <font color='red'>???????</font></html>

You could have the CSS first style the textbox, then have js change it:

<input type="text" style="background-color: yellow;" id="subEmail" />

js:

function changeColor() {
  document.getElementById("subEmail").style.backgroundColor = "Insert color here"
}

Just a note about the HtmlAgilityPack for posterity. The project contains an example of parsing text to html, which, as noted by the OP, does not handle whitespace at all like anyone writing HTML would envisage. There are full-text rendering solutions out there, noted by others to this question, which this is not (it cannot even handle tables in its current form), but it is lightweight and fast, which is all I wanted for creating a simple text version of HTML emails.

If you're on OpenWrt or using some old version of wget which doesn't gives you -i option:

#!/bin/bash
input="text_file.txt"
while IFS= read -r line
do
  wget $line
done < "$input"

Furthermore, if you don't have wget, you can use curl or whatever you use for downloading individual files.

I've had a few instances where I've needed inner shadows on text, and the following has worked out well for me:

.inner {
    color: rgba(252, 195, 67, 0.8);
    font-size: 48px;
    text-shadow: 1px 2px 3px #fff, 0 0 0 #000;
}

This sets the opacity of the text to 80%, and then creates two shadows:

• The first is a white shadow (assuming the text is on a white background) offset 1px from the left and 2px from the top, blurred 3px.
• The second is a black shadow which is visible through the 80% opacity text but not through the first shadow, which means it's visible inside the text letters only where the first shadow is displaced (1px from the left and 2px from the top). To change the blur of the this visible shadow, modify the blur parameter for the first layer shadow.

Caveats

• This will only work if the desired color of the text can be achieved without it having to be at 100% opacity.
• This will only work if the background color is solid (so, it won't work for the questioner's specific example where the text sits on a textured background).

this is my solution to the problem. I used it in a chatbot to replace the different words at once.

def mass_replace(text, dct):
    new_string = ""
    old_string = text
    while len(old_string) > 0:
        s = ""
        sk = ""
        for k in dct.keys():
            if old_string.startswith(k):
                s = dct[k]
                sk = k
        if s:
            new_string+=s
            old_string = old_string[len(sk):]
        else:
            new_string+=old_string[0]
            old_string = old_string[1:]
    return new_string

print mass_replace("The dog hunts the cat", {"dog":"cat", "cat":"dog"})

this will become The cat hunts the dog

It's also possible to assign newline and carriage return to variables and then append them to texts inside PowerShell scripts:

$OFS = "`r`n"
$msg = "This is First Line" + $OFS + "This is Second Line" + $OFS
Write-Host $msg

Perl string match can also be used for a simple yes/no.

my @foo=("hello", "world", "foo", "bar");

if ("@foo" =~ /\bhello\b/){
    print "found";
}
else{
    print "not found";
}

grep -n "YOUR SEARCH STRING" * > output-file

The -n will print the line number and the > will redirect grep-results to the output-file.
If you want to "clean" the results you can filter them using pipe | for example:
grep -n "test" * | grep -v "mytest" > output-file will match all the lines that have the string "test" except the lines that match the string "mytest" (that's the switch -v) - and will redirect the result to an output file.
A few good grep-tips can be found on this post

Wow, after few attempts I finally figured out how to deal with my text edits in vbs. The code works perfectly, it gives me the result I was expecting. Maybe it's not the best way to do this, but it does its job. Here's the code:

Option Explicit

Dim StdIn:  Set StdIn = WScript.StdIn
Dim StdOut: Set StdOut = WScript


Main()

Sub Main()

Dim objFSO, filepath, objInputFile, tmpStr, ForWriting, ForReading, count, text, objOutputFile, index, TSGlobalPath, foundFirstMatch
Set objFSO = CreateObject("Scripting.FileSystemObject")
TSGlobalPath = "C:\VBS\TestSuiteGlobal\Test suite Dispatch Decimal - Global.txt"
ForReading = 1
ForWriting = 2
Set objInputFile = objFSO.OpenTextFile(TSGlobalPath, ForReading, False)
count = 7
text=""
foundFirstMatch = false

Do until objInputFile.AtEndOfStream
    tmpStr = objInputFile.ReadLine
    If foundStrMatch(tmpStr)=true Then
        If foundFirstMatch = false Then
            index = getIndex(tmpStr)
            foundFirstMatch = true
            text = text & vbCrLf & textSubstitution(tmpStr,index,"true")
        End If
        If index = getIndex(tmpStr) Then
            text = text & vbCrLf & textSubstitution(tmpStr,index,"false")

    End If

Set objOutputFile = objFSO.CreateTextFile("C:\VBS\NuovaProva.txt", ForWriting, true)
objOutputFile.Write(text)
End Sub

strToAdd = "<tr><td><a href=" & chr(34) & "../../Logs/CF5.0_Features/Beginning_of_CF5.0_Features_TC" & CStr(index) & ".html" & chr(34) & ">Beginning_of_CF5.0_Features_TC" & CStr(index) & "</a></td></tr>"
If foundMatch = "false" Then
    textSubstitution = tmpStr
ElseIf foundMatch = "true" Then
    textSubstitution = strToAdd & vbCrLf & tmpStr
End If
End Function


Function getIndex(tmpStr)
Dim substrToFind, charAtPos, char1, char2
substrToFind = "<tr><td><a href=" & chr(34) & "../Test case "
charAtPos = len(substrToFind) + 1
char1 = Mid(tmpStr, charAtPos, 1)
char2 = Mid(tmpStr, charAtPos+1, 1)
If IsNumeric(char2) Then
    getIndex = CInt(char1 & char2)
Else
    getIndex = CInt(char1)
End If
End Function

Function foundStrMatch(tmpStr)
Dim substrToFind
substrToFind = "<tr><td><a href=" & chr(34) & "../Test case "
If InStr(tmpStr, substrToFind) > 0 Then
    foundStrMatch = true
Else
    foundStrMatch = false
End If
End Function

This is the original txt file

In your XML, you had used Textview, But in Java Code you had used EditText instead of TextView. If you change it into TextView you can set Text to to your TextView Object.

text = (TextView) findViewById(R.id.this_is_the_id_of_textview);
text.setText("TEST");

hope it will work.

It's easier to use only one code block, then you only need one redirection.

(
  echo Line1
  echo Line2
  ...
  echo Last Line
) > filename.txt

You must have a server-side script to handle your request, it can't be done using javascript.

To send raw data without URIencoding or escaping special characters to the php and save it as new txt file you can send ajax request using post method and FormData like:

JS:

var data = new FormData();
data.append("data" , "the_text_you_want_to_save");
var xhr = (window.XMLHttpRequest) ? new XMLHttpRequest() : new activeXObject("Microsoft.XMLHTTP");
xhr.open( 'post', '/path/to/php', true );
xhr.send(data);

PHP:

if(!empty($_POST['data'])){
$data = $_POST['data'];
$fname = mktime() . ".txt";//generates random name

$file = fopen("upload/" .$fname, 'w');//creates new file
fwrite($file, $data);
fclose($file);
}

Edit:

As Florian mentioned below, the XHR fallback is not required since FormData is not supported in older browsers (formdata browser compatibiltiy), so you can declare XHR variable as:

var xhr = new XMLHttpRequest();

Also please note that this works only for browsers that support FormData such as IE +10.

PdfTextStream (which you said you have been looking at) is now free for single threaded applications. In my opinion its quality is much better than other libraries (esp. for things like funky embedded fonts, etc).

Alternatively, you should have a look at Apache PDFBox, open source.

For people coming from the future, you can now do this purely in CSS.

.tooltip {
  position: relative;
  display: inline-block;
  border-bottom: 1px dotted black; 
  margin: 5rem;
}

/* Tooltip text */
.tooltip .tooltiptext {
  visibility: hidden;
  background-color: black;
  color: #fff;
  text-align: center;
  padding: 5px 0;
  border-radius: 6px;

  width: 120px;
  bottom: 100%;
  left: 50%;
  margin-left: -60px;

  position: absolute;
  z-index: 1;
}

/* Show the tooltip text when you mouse over the tooltip container */
.tooltip:hover .tooltiptext {
  visibility: visible;
}

<div class="tooltip">Hover over me
  <span class="tooltiptext">Tooltip text</span>
</div>

Replace whatever is in the address bar with this:

javascript:document.getElementById('serverTime').innerHTML='[text here]';

Example.

You can also use numpy loadtxt like

from numpy import loadtxt
lines = loadtxt("filename.dat", comments="#", delimiter=",", unpack=False)

There is an important detail that has been omitted in the answer above.

MySQL imposes a limit of 65,535 bytes for the max size of each row. The size of a VARCHAR column is counted towards the maximum row size, while TEXT columns are assumed to be storing their data by reference so they only need 9-12 bytes. That means even if the "theoretical" max size of your VARCHAR field is 65,535 characters you won't be able to achieve that if you have more than one column in your table.

Also note that the actual number of bytes required by a VARCHAR field is dependent on the encoding of the column (and the content). MySQL counts the maximum possible bytes used toward the max row size, so if you use a multibyte encoding like utf8mb4 (which you almost certainly should) it will use up even more of your maximum row size.

Correction: Regardless of how MySQL computes the max row size, whether or not the VARCHAR/TEXT field data is ACTUALLY stored in the row or stored by reference depends on your underlying storage engine. For InnoDB the row format affects this behavior. (Thanks Bill-Karwin)

Reasons to use TEXT:

• If you want to store a paragraph or more of text
• If you don't need to index the column
• If you have reached the row size limit for your table

Reasons to use VARCHAR:

• If you want to store a few words or a sentence
• If you want to index the (entire) column
• If you want to use the column with foreign-key constraints

Working my way through Fluent Python (Ramalho) - highly recommended. List comprehension one-ish-liners inspired by Chapter 2:

onlyascii = ''.join([s for s in data if ord(s) < 127])
onlymatch = ''.join([s for s in data if s in
              'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'])

A part from @djechlin answer, you should change the rows and columns. Since you are taken as 7 rows and 5 columns, but actually you want is 7 columns and 5 rows.

Do this way:-

int twoDm[][]= new int[5][7];

for(i=0;i<5;i++){
    for(j=0;j<7;j++) {
        System.out.print(twoDm[i][j]+" ");
    }
    System.out.println("");
}

I suposse this is the output you need:

title,intro,tagline

2.9,Gardena,CA

It can be done with this changes to your code:

import csv
import itertools

with open('log.txt', 'r') as in_file:
    lines = in_file.read().splitlines()
    stripped = [line.replace(","," ").split() for line in lines]
    grouped = itertools.izip(*[stripped]*1)
    with open('log.csv', 'w') as out_file:
        writer = csv.writer(out_file)
        writer.writerow(('title', 'intro', 'tagline'))
        for group in grouped:
            writer.writerows(group)

I would use a for loop to iterate over the lines in the text file:

for line in my_text:
    outputfile.writelines(data_parser(line, reps))

If you want to read the file line-by-line instead of loading the whole thing at the start of the script you could do something like this:

inputfile = open('test.dat')
outputfile = open('test.csv', 'w')

# sample text string, just for demonstration to let you know how the data looks like
# my_text = '"2012-06-23 03:09:13.23",4323584,-1.911224,-0.4657288,-0.1166382,-0.24823,0.256485,"NAN",-0.3489428,-0.130449,-0.2440527,-0.2942413,0.04944348,0.4337797,-1.105218,-1.201882,-0.5962594,-0.586636'

# dictionary definition 0-, 1- etc. are there to parse the date block delimited with dashes, and make sure the negative numbers are not effected
reps = {'"NAN"':'NAN', '"':'', '0-':'0,','1-':'1,','2-':'2,','3-':'3,','4-':'4,','5-':'5,','6-':'6,','7-':'7,','8-':'8,','9-':'9,', ' ':',', ':':',' }

for i in range(4): inputfile.next() # skip first four lines
for line in inputfile:
    outputfile.writelines(data_parser(line, reps))

inputfile.close()
outputfile.close()

You could do this using ANSI escape sequences. I've actually put together this class in Java for anyone that would like a simple workaround for this. It allows for more than just color codes.

https://gist.github.com/nathan-fiscaletti/9dc252d30b51df7d710a

(Ported from: https://github.com/nathan-fiscaletti/ansi-util)

Example Use:

StringBuilder sb = new StringBuilder();

System.out.println(
    sb.raw("Hello, ")
      .underline("John Doe")
      .resetUnderline()
      .raw(". ")
      .raw("This is ")
      .color16(StringBuilder.Color16.FG_RED, "red")
      .raw(".")
);

In SQL Server , cast text as datetime

select cast('5/21/2013 9:45:48' as datetime)

Using BeautifulSoup the easiest way with less code to just get the strings, without empty lines and crap.

tag = <Parent_Tag_that_contains_the_data>
soup = BeautifulSoup(tag, 'html.parser')

for i in soup.stripped_strings:
    print repr(i)

Another solution to the problem could be the following set of CSS rules:

.ellipsis{
 white-space:nowrap;
 overflow:hidden;
}

.ellipsis:after{
  content:'...';
}

The only drawback with the above CSS is that it would add the "..." irrespective of whether the text-overflows the container or not. Still, if you have a case where you have a bunch of elements and are sure that content will overflow, this one would be a simpler set of rules.

My two cents. Hats off to the original technique by Justin Maxwell

To make part of your text underlined and colored

in your strings.xml

<string name="text_with_colored_underline">put the text here and &lt;u>&lt;font color="#your_hexa_color">the underlined colored part here&lt;font>&lt;u></string>

then in the activity

yourTextView.setText(Html.fromHtml(getString(R.string.text_with_colored_underline)));

and for clickable links:

<string name="text_with_link"><![CDATA[<p>text before link<a href=\"http://www.google.com\">title of link</a>.<p>]]></string>

and in your activity:

yourTextView.setText(Html.fromHtml(getString(R.string.text_with_link)));
yourTextView.setMovementMethod(LinkMovementMethod.getInstance());

If all other options have failed, trying recreating the data import task and/or the connection manager. If you've made any changes since the task was originally created, this can sometimes do the trick. I know it's the equivalent of rebooting, but, hey, if it works, it works.

Use:

<Text>{`Hi,\nCurtis!`}</Text>

Result:

Hi,

Curtis!

Browsers are beginning to support advanced text metrics, which will make this task trivial when it's widely supported:

let metrics = ctx.measureText(text);
let fontHeight = metrics.fontBoundingBoxAscent + metrics.fontBoundingBoxDescent;
let actualHeight = metrics.actualBoundingBoxAscent + metrics.actualBoundingBoxDescent;

fontHeight gets you the bounding box height that is constant regardless of the string being rendered. actualHeight is specific to the string being rendered.

Spec: https://www.w3.org/TR/2012/CR-2dcontext-20121217/#dom-textmetrics-fontboundingboxascent and the sections just below it.

Support status (20-Aug-2017):

• Chrome has it behind a flag (https://bugs.chromium.org/p/chromium/issues/detail?id=277215).
• Firefox has it in development (https://bugzilla.mozilla.org/show_bug.cgi?id=1102584).
• Edge has no support (https://wpdev.uservoice.com/forums/257854-microsoft-edge-developer/suggestions/30922861-advanced-canvas-textmetrics).
• node-canvas (node.js module), mostly supported (https://github.com/Automattic/node-canvas/wiki/Compatibility-Status).

If you have bad luck and still has to use JSF 1, then the only solution is to use ­, ­ does not work.

You can use this my custom label! You can also use interface builder to set

import UIKit


class  YHYAttributedLabel : UILabel{
    
    
    @IBInspectable
    var underlineText : String = ""{
        
        didSet{

            self.attributedText = NSAttributedString(string: underlineText,
            attributes: [NSAttributedString.Key.underlineStyle: NSUnderlineStyle.single.rawValue])
        }
        
        
    }

}

nvarchar(max) is what you want to be using. The biggest advantage is that you can use all the T-SQL string functions on this data type. This is not possible with ntext. I'm not aware of any real disadvantages.

in my case, the file command tells a wrong encoding, so i tried converting with all the possible encodings, and found out the right one.

execute this script and check the result file.

for i in `iconv -l`
do
   echo $i
   iconv -f $i -t UTF-8 yourfile | grep "hint to tell converted success or not"
done &>/tmp/converted

Use try with resources. this will automatically close the resources.

try (BufferedReader br = new BufferedReader(new FileReader("C:/test.txt"))) {
    String line;
    while ((line = br.readLine()) != null) {
        System.out.println(line);
    }
} catch (Exception e) {

}

There is an appropriate PHP function: substr_replace($text, $replacement, $start).

For your case, because you already know all the possibilities of the text length (100, 1000 or 10000 words), you can simply use that PHP function like this:

echo substr_replace($your_text, "...", 20);

PHP will automatically return a 20 character only text with ....

Se the documentation by clicking here.

Pipe the content of your

Get-ChildItem -recurse | Get-Content | Select-String -pattern "dummy"

to fl *

You will see that the path is already being returned as a property of the objects.

IF you want just the path, use select path or select -unique path to remove duplicates:

Get-ChildItem -recurse | Get-Content | Select-String -pattern "dummy" | select -unique path

Use the File.WriteAllText method. It creates the file if it doesn't exist and overwrites it if it exists.

How about:

echo "hello" >> <filename>

Using the >> operator will append data at the end of the file, while using the > will overwrite the contents of the file if already existing.

You could also use printf in the same way:

printf "hello" >> <filename>

Note that it can be dangerous to use the above. For instance if you already have a file and you need to append data to the end of the file and you forget to add the last > all data in the file will be destroyed. You can change this behavior by setting the noclobber variable in your .bashrc:

set -o noclobber

Now when you try to do echo "hello" > file.txt you will get a warning saying cannot overwrite existing file.

To force writing to the file you must now use the special syntax:

echo "hello" >| <filename>

You should also know that by default echo adds a trailing new-line character which can be suppressed by using the -n flag:

echo -n "hello" >> <filename>

References

• echo(1) - Linux man page
• noclobber variable
• I/O Redirection

You could use CSS for this and create classes for the elements. So you'd have something like this

p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }

Then your HTML would read:

<p class="detail">My Name is: <span class="name">Tintinecute</span> </p>

It's a lot neater then inline stylesheets, is easier to maintain and provides greater reuse.

Here's the complete HTML to demonstrate what I mean:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <style type="text/css">
    p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
    span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }
    </style>
</head>
<body>
    <p class="detail">My Name is: <span class="name">Tintinecute</span> </p>
</body>
</html>     

You'll see that I have the stylesheet classes in a style tag in the header, and then I only apply those classes in the code such as <p class="detail"> ... </p>. Go through the w3schools tutorial, it will only take a couple of hours and will really turn you around when it comes to styling your HTML elements. If you cut and paste that into an HTML document you can edit the styles and see what effect they have when you open the file in a browser. Experimenting like this is a great way to learn.

:.,$d

This will delete all content from current line to end of the file. This is very useful when you're dealing with test vector generation or stripping.

Try this code to use:

/* For Mozile Firefox Browser */

::-moz-selection { background-color: #4CAF50; }

/* For Other Browser*/
::selection { background-color: #4CAF50; }

That's not possible with CSS, you will have to use the Javascript for that. Although you can set the width of the p to as much as 30 characters and next letters will automatically come down but again this won't be that accurate and will vary if the characters are in capital.

in my opinion strstr() is better than strpos(). because strstr() is compatible with both PHP 4 AND PHP 5. but strpos() is only compatible with PHP 5. please note that part of servers have no PHP 5

Above Code JAVA version: Thanks @William

public static List<Rect> detectLetters(Mat img){    
    List<Rect> boundRect=new ArrayList<>();

    Mat img_gray =new Mat(), img_sobel=new Mat(), img_threshold=new Mat(), element=new Mat();
    Imgproc.cvtColor(img, img_gray, Imgproc.COLOR_RGB2GRAY);
    Imgproc.Sobel(img_gray, img_sobel, CvType.CV_8U, 1, 0, 3, 1, 0, Core.BORDER_DEFAULT);
    //at src, Mat dst, double thresh, double maxval, int type
    Imgproc.threshold(img_sobel, img_threshold, 0, 255, 8);
    element=Imgproc.getStructuringElement(Imgproc.MORPH_RECT, new Size(15,5));
    Imgproc.morphologyEx(img_threshold, img_threshold, Imgproc.MORPH_CLOSE, element);
    List<MatOfPoint> contours = new ArrayList<MatOfPoint>();
    Mat hierarchy = new Mat();
    Imgproc.findContours(img_threshold, contours,hierarchy, 0, 1);

    List<MatOfPoint> contours_poly = new ArrayList<MatOfPoint>(contours.size());

     for( int i = 0; i < contours.size(); i++ ){             

         MatOfPoint2f  mMOP2f1=new MatOfPoint2f();
         MatOfPoint2f  mMOP2f2=new MatOfPoint2f();

         contours.get(i).convertTo(mMOP2f1, CvType.CV_32FC2);
         Imgproc.approxPolyDP(mMOP2f1, mMOP2f2, 2, true); 
         mMOP2f2.convertTo(contours.get(i), CvType.CV_32S);


            Rect appRect = Imgproc.boundingRect(contours.get(i));
            if (appRect.width>appRect.height) {
                boundRect.add(appRect);
            }
     }

    return boundRect;
}

And use this code in practice :

        System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
        Mat img1=Imgcodecs.imread("abc.png");
        List<Rect> letterBBoxes1=Utils.detectLetters(img1);

        for(int i=0; i< letterBBoxes1.size(); i++)
            Imgproc.rectangle(img1,letterBBoxes1.get(i).br(), letterBBoxes1.get(i).tl(),new Scalar(0,255,0),3,8,0);         
        Imgcodecs.imwrite("abc1.png", img1);

Same happened to me, I had to go into Packages and re-enable Tabs and Tree-View (both part of core).

Just adding to Tony Miller's answer as this got me 90% towards what I was looking for but still didn't work. Adding .length > 0; to the end of his code got my script working.

 $(function() {
    var foundin = $('*:contains("I am a simple string")').length > 0;
 });

Here is my answer:

    def draw_text(text, font_name, size, color, x, y, align="nw"):
        font = pg.font.Font(font_name, size)
        text_surface = font.render(text, True, color)
        text_rect = text_surface.get_rect()
        if align == "nw":
            text_rect.topleft = (x, y)
        if align == "ne":
            text_rect.topright = (x, y)
        if align == "sw":
            text_rect.bottomleft = (x, y)
        if align == "se":
            text_rect.bottomright = (x, y)
        if align == "n":
            text_rect.midtop = (x, y)
        if align == "s":
            text_rect.midbottom = (x, y)
        if align == "e":
            text_rect.midright = (x, y)
        if align == "w":
            text_rect.midleft = (x, y)
        if align == "center":
            text_rect.center = (x, y)
        screen.blit(text_surface, text_rect)

Of course, you'll need to import pygame, a font and a screen, but this is just a def to add on to the rest of the code, and then call "draw_text".

Here is the solution

TextView questionValue = (TextView) findViewById(R.layout.TextView01);
questionValue.setTypeface(null, Typeface.BOLD);

Got the same problem but didn't found a good solution yet for detecting it automatically . Now im using PsPad (www.pspad.com) for that ;) Works fine

A minor edition to @sastanin's solution, so that it can deal with newlines within quotes.

std::vector<std::vector<std::string>> readCSV(std::istream &in) {
    std::vector<std::vector<std::string>> table;

    while (!in.eof()) {
        CSVState state = CSVState::UnquotedField;
        std::vector<std::string> fields {""};
        size_t i = 0; // index of the current field
        for (char c : row) {
            switch (state) {
                case CSVState::UnquotedField:

                        case '\n': // newline
                                  table.push_back(fields);
                                  state = CSVState::UnquotedField;
                                  fields = vector<string>{""};
                                  i = 0;
                        default:  // end of quote
                                  state = CSVState::UnquotedField;
                                  break; }
                    break;
            }
        }
    }
    return table;
}

In order to be able to justify the text, you need to know the width of the image. You can just use the normal width of the image, or use a different width, but IE 6 might get cranky at you and not scale.

Here's what you need:

<style type="text/css">
#container { width: 100px; //whatever width you want }

#image {width: 100%; //fill up whole div }

#text { text-align: justify; }    
</style>

 <div id="container"> 
     <img src="" id="image" /> 
     <p id="text">oooh look! text!</p> 
 </div>

opacity will make both text and background transparent. Use a semi-transparent background-color instead, by using a rgba() value for example. Works on IE8+

 $<input name="currency">

See also: Restricting input to textbox: allowing only numbers and decimal point

This worked for me with inline text. It was tested in Firefox, Safari, Chrome, and Opera.

<p>Lorem ipsum dolor sit amet, consectetur <span>Some Text</span> adipiscing elit.</p>

span {
    visibility: hidden;
    word-spacing: -999px;
    letter-spacing: -999px;
}

span:after {
    content: "goodbye";
    visibility: visible;
    word-spacing: normal;
    letter-spacing: normal;
}

Just append() the text nodes:

$('#replyBox').append(quote); 

http://jsfiddle.net/nQErc/

This command:

iconv -f utf-8 -t utf-8 -c file.txt

will clean up your UTF-8 file, skipping all the invalid characters.

-f is the source format
-t the target format
-c skips any invalid sequence

Centered and middled content ?

Do it this way :

<table style="width:100%">
    <tr>
        <td valign="middle" align="center">Table once ruled centering</td>
    </tr>
</table>

I fiddled it here

Ha, let me guess .. you want DIVs ..

just make your first outter DIV behave like a table-cell then style it with vertical align:middle;

<div>
    <p>I want this paragraph to be at the center, but I can't.</p>
</div>

div {
    width:500px;
    height:100px;
    background-color:aqua;
    text-align:center;
    /*  there it is */
    display:table-cell;
    vertical-align:middle;
}

Android does not yet support full justification. We can use Webview and justify HTML instead of using textview. It works so fine. If you guys not clear, feel free to ask me :)

Simple JAVA code to calculate cosine similarity

  private double cosineSimilarity(List<Double> vector1, List<Double> vector2) {

    double normA = 0.0;
    double normB = 0.0;
    for (int i = 0; i < vector1.size(); i++) {
      dotProduct += vector1.get(i) * vector2.get(i);
      normA += Math.pow(vector1.get(i), 2);
      normB += Math.pow(vector2.get(i), 2);
    }
    return dotProduct / (Math.sqrt(normA) * Math.sqrt(normB));
  }

I know this question has been and gone, but if anyone else stumbled across this I wanted to let them know. This may sound an unintuitive thing to do but you could use a button with clickable set to false or what ever. This is because a button allows one to set drawableLeft, drawableRight, drawableTop etc in addition to text.

  <Button
  android:id="@+id/button1"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:background="@drawable/border_box1"
  android:drawableLeft="@drawable/ar9_but_desc"
  android:padding="20dp"
  android:text="@string/ar4_button1"
  android:textColor="@color/white"
  android:textSize="24sp" />

New Info: A button can have icons in drawableLeft, drawableRight, drawableTop, and drawableBottom. This makes a standard button much more flexible than an image button. The left, right, top etc is the relation to the text in the button. You can have multiple drawables on the button for example one left, one right and the text in the middle.

Given that Windows has no sys/socket.h, you might consider just doing something like this:

#ifdef __WIN32__
# include <winsock2.h>
#else
# include <sys/socket.h>
#endif

I know you indicated that you won't use WinSock, but since WinSock is how TCP networking is done under Windows, I don't see that you have any alternative. Even if you use a cross-platform networking library, that library will be calling WinSock internally. Most of the standard BSD sockets API calls are implemented in WinSock, so with a bit of futzing around, you can make the same sockets-based program compile under both Windows and other OS's. Just don't forget to do a

#ifdef __WIN32__
   WORD versionWanted = MAKEWORD(1, 1);
   WSADATA wsaData;
   WSAStartup(versionWanted, &wsaData);
#endif

at the top of main()... otherwise all of your socket calls will fail under Windows, because the WSA subsystem wasn't initialized for your process.

You need to "clear" the float after every 6 images. So with your current code, change the styles for containerdivNewLine to:

.containerdivNewLine { clear: both; float: left; display: block; position: relative; } 

Given some of the answers, to get the actual swap and RAM for a single application I came up with the following, say we want to know what 'firefox' is using

sudo smem | awk '/firefox/{swap+=$5; pss+=$7;}END{print "swap = "swap/1024" PSS = "pss/1024}'
or for libvirt;
sudo smem | awk '/libvirt/{swap+=$5; pss+=$7;}END{print "swap = "swap/1024" PSS = "pss/1024}'

this will give you the total in MB like so;

swap = 0 PSS = 2096.92
swap = 224.75 PSS = 421.455

No one here posted an answer with all of the correct CSS variations, so here it is:

-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;

Extending on Henry's example:

import tempfile
import shutil

FILE_UPLOAD_DIR = '/home/imran/uploads'

def handle_uploaded_file(source):
    fd, filepath = tempfile.mkstemp(prefix=source.name, dir=FILE_UPLOAD_DIR)
    with open(filepath, 'wb') as dest:
        shutil.copyfileobj(source, dest)
    return filepath

You can call this handle_uploaded_file function from your view with the uploaded file object. This will save the file with a unique name (prefixed with filename of the original uploaded file) in filesystem and return the full path of saved file. You can save the path in database, and do something with the file later.

public int GetResult(List<int> list){
int first = list.First();
return list.All(x => x == first) ? first : SOME_OTHER_VALUE;
}

The way i usually have my hierarchy of folder-

It's likely that the download was corrupted if you are getting an error with the disk image. Go back to the downloads page at https://developers.google.com/appengine/downloads and look at the SHA1 checksum. Then, go to your Terminal app on your mac and run the following:

openssl sha1 [put the full path to the file here without brackets] 

For example:

openssl sha1 /Users/me/Desktop/myFile.dmg 

If you get a different value than the one on the Downloads page, you know your file is not properly downloaded and you should try again.

Use split()

let mut split = "some string 123 ffd".split("123");

This gives an iterator, which you can loop over, or collect() into a vector.

for s in split {
    println!("{}", s)
}
let vec = split.collect::<Vec<&str>>();
// OR
let vec: Vec<&str> = split.collect();

troubleshooting-friendly style

You should not call .get() directly. Optional<>, that Stream::max returns, was designed to benefit from .orElse... inline handling.

If you are sure your arguments have their size of 2+:

list.stream()
    .map(u -> u.date)
    .max(Date::compareTo)
    .orElseThrow(() -> new IllegalArgumentException("Expected 'list' to be of size: >= 2. Was: 0"));

If you support empty lists, then return some default value, for example:

list.stream()
    .map(u -> u.date)
    .max(Date::compareTo)
    .orElse(new Date(Long.MIN_VALUE));

To exec into a running container named test, below is the following commands

If the container has bash shell

docker exec -it test /bin/bash

If the container has bourne shell and most of the cases it's present

docker run -it test /bin/sh

Answered a question such as this before, you can take a look at the results here:

Creating form to have fields and text next to each other - what is the semantic way to do it?

So to apply the same rules to your fiddle you can use display:inline-block to display your label and input groups side by side, like so:

CSS

input {
    margin-top: 5px;
    margin-bottom: 5px;
    display:inline-block;
    *display: inline;     /* for IE7*/
    zoom:1;              /* for IE7*/
    vertical-align:middle;
    margin-left:20px
}

label {
    display:inline-block;
    *display: inline;     /* for IE7*/
    zoom:1;              /* for IE7*/
    float: left;
    padding-top: 5px;
    text-align: right;
    width: 140px;
}

My use case: In my react app, Upon user click there is an API call performed to the backend. Based on the response, new tab is opened with the api response added as params to the new tab URL (in same domain).

The only caveat in my use case is that it takes more for 1 second for the API response to be received. Hence pop-up blocker shows up (if it is active) when opening up URL in a new tab.

To circumvent the above described issue, here is the sample code,

var new_tab=window.open()
axios.get('http://backend-api').then(response=>{
    const url="http://someurl"+"?response"
    new_tab.location.href=url;
}).catch(error=>{
    //catch error
})

Summary: Create an empty tab (as above line 1) and when the API call is completed, you can fill up the tab with the url and skip the popup blocker.

If you have a Java 8 Clock, then you can use clock.millis() (although it recommends you use clock.instant() to get a Java 8 Instant, as it's more accurate).

Why would you use a Java 8 clock? So in your DI framework you can create a Clock bean:

@Bean
public Clock getClock() {
    return Clock.systemUTC();
}

and then in your tests you can easily Mock it:

@MockBean private Clock clock;

or you can have a different bean:

@Bean
public Clock getClock() {
    return Clock.fixed(instant, zone);
}

which helps with tests that assert dates and times immeasurably.

If the list is sorted (as happens to be in the example) a binary search on index certainly works.

    public static Dog Find(List<Dog> AllDogs, string Id)
    {
        int p = 0;
        int n = AllDogs.Count;
        while (true)
        {
            int m = (n + p) / 2;
            Dog d = AllDogs[m];
            int r = string.Compare(Id, d.Id);
            if (r == 0)
                return d;
            if (m == p)
                return null;
            if (r < 0)
                n = m;
            if (r > 0)
                p = m;
        }
    }

Not sure what the LINQ version of this would be.

It is very easy to do, all you need to do is 1) download 5.6 from [1]: https://sourceforge.net/projects/xampp/files/XAMPP%20Windows/5.6.36/, the run the setup and install in folder "xampp"

2) download 7.6 from [https://sourceforge.net/projects/xampp/files/XAMPP%20Windows/7.4.2/xampp-portable-windows-x64-7.4.2-0-VC15-installer.exe/download][1] and run the setup in "xampp2"

NOte: after that you now have separate xampp installed in your system. all you do now is to run each xampp as a separate entity. Alway quite the 5.6 if you want to run 7.6

There is one thing that may be optimized in the suggested solutions. Having many calls to Replace() makes the code to do multiple passes over the same string. With very long strings the solutions may be slow because of CPU cache capacity misses. May be one should consider replacing multiple strings in a single pass.

You could make it through iframes... I made something, but my only problem for now is syncing those divs to scroll simultaneous... its terrible way, because its like you load 2 websites, but the only way I found... you could also work with divs and overflow I guess...

you have to do like this in your project level gradle file

allprojects {
    repositories {
        jcenter()
        maven { url "http://dl.appnext.com/" }
        maven { url "https://maven.google.com" }
    }
}

using vector::insert (const_iterator position, initializer_list il); http://www.cplusplus.com/reference/vector/vector/insert/

#include <iostream>
#include <vector>

int main() {
  std::vector<int> vec;
  vec.insert(vec.end(),{1,2,3,4});
  return 0;
}

As an alternate to adding a comma for each item you could just using String.Join:

var strgroupids = String.Join(",",  groupIds);

This will add the seperator ("," in this instance) between each element in the array.

This is working Oracle example but it should work in MySQL too.

You are missing smth - see IN after END Replace 'IN' with '=' sign for a single value.

SELECT empno, ename, job
  FROM scott.emp
 WHERE (CASE WHEN job = 'MANAGER' THEN '1'  
         WHEN job = 'CLERK'   THEN '2' 
         ELSE '0'  END) IN (1, 2)

You can also do it this way without the need of Linq:

List<int> numbers = new List<int>( Array.ConvertAll(sNumbers.Split(','), int.Parse) );

// Uses Linq
var numbers = Array.ConvertAll(sNumbers.Split(','), int.Parse).ToList();

code example with java 8+:

public class Person implements Serializable {

private String lastName;
private String firstName;

public Person() {
}

public Person(String firstName, String lastName) {
    this.firstName = firstName;
    this.lastName = lastName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public String getFirstName() {
    return firstName;
}

public String getLastName() {
    return lastName;
}

public void setLastName(String lastName) {
    this.lastName = lastName;
}

@Override
public String toString() {
    return "firstName: " + firstName + ", lastName: " + lastName;
}
}


public interface PersonMarshaller {
default Person fromStream(InputStream inputStream) {
    try (ObjectInputStream objectInputStream = new ObjectInputStream(inputStream)) {
        Person person= (Person) objectInputStream.readObject();
        return person;
    } catch (IOException | ClassNotFoundException e) {
        System.err.println(e.getMessage());
        return null;
    }
}

default OutputStream toStream(Person person) {
    try (OutputStream outputStream = new ByteArrayOutputStream()) {
        ObjectOutput objectOutput = new ObjectOutputStream(outputStream);
        objectOutput.writeObject(person);
        objectOutput.flush();
        return outputStream;
    } catch (IOException e) {
        System.err.println(e.getMessage());
        return null;
    }

}

}

Since the img is an inline element, Just use text-center on it's container. Using mx-auto will center the container (column) too.

<div class="row">
    <div class="col-4 mx-auto text-center">
        <img src="..">
    </div>
</div>

By default, images are display:inline. If you only want the center the image (and not the other column content), make the image display:block using the d-block class, and then mx-auto will work.

<div class="row">
  <div class="col-4">
    <img class="mx-auto d-block" src="..">
  </div>
</div>

I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer

You can't. You can only have one slide size and one orientation per presentation.

Are you projecting the presentation or delivering it on a laptop? If so, the size is sort of irrelevant.
Regardless of the slide size, the projected/displayed image will never be longer or wider than the projector/display accepts.

Another approach is to unload some logic from the backend and maek the browser do the job by using Javascript plugins such as:

jQuery time ago or its Rails Gem adaptation

The CGRectZero constant is equal to a rectangle at position (0,0) with zero width and height. This is fine to use, and actually preferred, if you use AutoLayout, since AutoLayout will then properly place the view.

But, I expect you do not use AutoLayout. So the most simple solution is to specify the size of the custom view by providing a frame explicitly:

customView = MyCustomView(frame: CGRect(x: 0, y: 0, width: 200, height: 50))
self.view.addSubview(customView)

Note that you also need to use addSubview otherwise your view is not added to the view hierarchy.

As it turns out, Git is smart enough not to drop a stash if it doesn't apply cleanly. I was able to get to the desired state with the following steps:

1. To unstage the merge conflicts: git reset HEAD . (note the trailing dot)
2. To save the conflicted merge (just in case): git stash
3. To return to master: git checkout master
4. To pull latest changes: git fetch upstream; git merge upstream/master
5. To correct my new branch: git checkout new-branch; git rebase master
6. To apply the correct stashed changes (now 2nd on the stack): git stash apply stash@{1}

you can try this:

$('div#someDiv').height('');

Try using TempData:

public ActionResult Create(FormCollection collection) {
  ...
  TempData["notice"] = "Successfully registered";
  return RedirectToAction("Index");
  ...
}

Then, in your Index view, or master page, etc., you can do this:

<% if (TempData["notice"] != null) { %>
  <p><%= Html.Encode(TempData["notice"]) %></p>
<% } %>

Or, in a Razor view:

@if (TempData["notice"] != null) {
  <p>@TempData["notice"]</p>
}

Quote from MSDN (page no longer exists as of 2014, archived copy here):

An action method can store data in the controller's TempDataDictionary object before it calls the controller's RedirectToAction method to invoke the next action. The TempData property value is stored in session state. Any action method that is called after the TempDataDictionary value is set can get values from the object and then process or display them. The value of TempData persists until it is read or until the session times out. Persisting TempData in this way enables scenarios such as redirection, because the values in TempData are available beyond a single request.

dplyr >= 1.0.0 using across

sum up each row using rowSums (rowwise works for any aggreation, but is slower)

df %>%
   replace(is.na(.), 0) %>%
   mutate(sum = rowSums(across(where(is.numeric))))

sum down each column

df %>%
   summarise(across(everything(), ~ sum(., is.na(.), 0)))

dplyr < 1.0.0

sum up each row

df %>%
   replace(is.na(.), 0) %>%
   mutate(sum = rowSums(.[1:5]))

sum down each column using superseeded summarise_all:

df %>%
   replace(is.na(.), 0) %>%
   summarise_all(funs(sum))

Sure. The easiest is probably to write a wrapper around preg_match:

function limitString($string, $limit = 100) {
    // Return early if the string is already shorter than the limit
    if(strlen($string) < $limit) {return $string;}

    $regex = "/(.{1,$limit})\b/";
    preg_match($regex, $string, $matches);
    return $matches[1];
}

EDIT : Updated to not ALWAYS include a space as the last character in the string

nzd$date <- format(as.Date(nzd$date), "%Y/%m/%d")

In the above piece of code, there are two mistakes. First of all, when you are reading nzd$date inside as.Date you are not mentioning in what format you are feeding it the date. So, it tries it's default set format to read it. If you see the help doc, ?as.Date you will see

format
A character string. If not specified, it will try "%Y-%m-%d" then "%Y/%m/%d" on the first non-NA element, and give an error if neither works. Otherwise, the processing is via strptime

The second mistake is: even though you would like to read it in %Y-%m-%d format, inside format you wrote "%Y/%m/%d".

Now, the correct way of doing it is:

> nzd <- data.frame(date=c("31/08/2011", "31/07/2011", "30/06/2011"), 
+                                       mid=c(0.8378,0.8457,0.8147))
> nzd
        date    mid
1 31/08/2011 0.8378
2 31/07/2011 0.8457
3 30/06/2011 0.8147
> nzd$date <- format(as.Date(nzd$date, format = "%d/%m/%Y"), "%Y-%m-%d")
> head(nzd)
        date    mid
1 2011-08-31 0.8378

In my case I imported pyxlsd module before module wich works with db Mysql. After I did put Mysql module first(upper in code) it became to work like a clock. Think there was some namespace issue.

They should be exactly the same. However, as a coding practice, I would rather see the Join. It clearly articulates your intent,

in build.gradle add Guava

    compile group: 'com.google.guava', name: 'guava', version: '27.0-jre'

and then

    public static List<String> splitByComma(String str) {
    Iterable<String> split = Splitter.on(",")
            .omitEmptyStrings()
            .trimResults()
            .split(str);
    return Lists.newArrayList(split);
    }

    public static String joinWithComma(Set<String> words) {
        return Joiner.on(", ").skipNulls().join(words);
    }

enjoy :)

For ease of use, ctypes is the way to go.

The following example of ctypes is from actual code I've written (in Python 2.5). This has been, by far, the easiest way I've found for doing what you ask.

import ctypes

# Load DLL into memory.

hllDll = ctypes.WinDLL ("c:\\PComm\\ehlapi32.dll")

# Set up prototype and parameters for the desired function call.
# HLLAPI

hllApiProto = ctypes.WINFUNCTYPE (
    ctypes.c_int,      # Return type.
    ctypes.c_void_p,   # Parameters 1 ...
    ctypes.c_void_p,
    ctypes.c_void_p,
    ctypes.c_void_p)   # ... thru 4.
hllApiParams = (1, "p1", 0), (1, "p2", 0), (1, "p3",0), (1, "p4",0),

# Actually map the call ("HLLAPI(...)") to a Python name.

hllApi = hllApiProto (("HLLAPI", hllDll), hllApiParams)

# This is how you can actually call the DLL function.
# Set up the variables and call the Python name with them.

p1 = ctypes.c_int (1)
p2 = ctypes.c_char_p (sessionVar)
p3 = ctypes.c_int (1)
p4 = ctypes.c_int (0)
hllApi (ctypes.byref (p1), p2, ctypes.byref (p3), ctypes.byref (p4))

The ctypes stuff has all the C-type data types (int, char, short, void*, and so on) and can pass by value or reference. It can also return specific data types although my example doesn't do that (the HLL API returns values by modifying a variable passed by reference).

In terms of the specific example shown above, IBM's EHLLAPI is a fairly consistent interface.

All calls pass four void pointers (EHLLAPI sends the return code back through the fourth parameter, a pointer to an int so, while I specify int as the return type, I can safely ignore it) as per IBM's documentation here. In other words, the C variant of the function would be:

int hllApi (void *p1, void *p2, void *p3, void *p4)

This makes for a single, simple ctypes function able to do anything the EHLLAPI library provides, but it's likely that other libraries will need a separate ctypes function set up per library function.

The return value from WINFUNCTYPE is a function prototype but you still have to set up more parameter information (over and above the types). Each tuple in hllApiParams has a parameter "direction" (1 = input, 2 = output and so on), a parameter name and a default value - see the ctypes doco for details

Once you have the prototype and parameter information, you can create a Python "callable" hllApi with which to call the function. You simply create the needed variable (p1 through p4 in my case) and call the function with them.

The current best practice is to configure Jackson within the application.yml (or properties) file.

Example:

spring:
  jackson:
    property-naming-strategy: SNAKE_CASE

If you have more complex configuration requirements, you can also configure Jackson programmatically.

import com.fasterxml.jackson.databind.PropertyNamingStrategy;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;

@Configuration
public class JacksonConfiguration {

    @Bean
    public Jackson2ObjectMapperBuilder jackson2ObjectMapperBuilder() {
        return new Jackson2ObjectMapperBuilder()
                .propertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);
        // insert other configurations
    }

} 

This is a simple JavaScript sound recorder and editor. You can try it.

https://www.danieldemmel.me/JSSoundRecorder/

Can download from here

https://github.com/daaain/JSSoundRecorder

declare you array as:

$car = array("bmw")

EDIT

now with powershell syntax:)

$car = [array]"bmw"

There is no WPF equivalent. System.Windows.Forms.Screen is still part of the .NET framework and can be used from WPF though.

See this question for more details, but you can use the calls relating to screens by using the WindowInteropHelper class to wrap your WPF control.

In my case I fixed this issue like below:-

1. First I removed (apache) C:\Users\myuserId\.m2\repository\org\apache

2. I added below dependencies in my pom.xml file

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   

3. I have changed the default socket by adding below lines in resource file ..\yourprojectfolder\src\main\resourcesand\application.properties(I manually created this file)

    server.port=8099
    [email protected]@
   

   for that I have added below block in my pom.xml under <build> section.

     <build>
     .
     .
    <resources>
       <resource>
           <directory>src/main/resources</directory>

       </resource>
   </resources>
      .
      .    
     </build>
   

My final pom.xml file look like

For Rails4:

So, what you're wanting is an inner join, so you really should just use the joins predicate:

  Foo.joins(:bar)

  Select * from Foo Inner Join Bars ...

But, for the record, if you want a "NOT NULL" condition simply use the not predicate:

Foo.includes(:bar).where.not(bars: {id: nil})

Select * from Foo Left Outer Join Bars on .. WHERE bars.id IS NOT NULL

Note that this syntax reports a deprecation (it talks about a string SQL snippet, but I guess the hash condition is changed to string in the parser?), so be sure to add the references to the end:

Foo.includes(:bar).where.not(bars: {id: nil}).references(:bar)

DEPRECATION WARNING: It looks like you are eager loading table(s) (one of: ....) that are referenced in a string SQL snippet. For example:

Post.includes(:comments).where("comments.title = 'foo'")

Currently, Active Record recognizes the table in the string, and knows to JOIN the comments table to the query, rather than loading comments in a separate query. However, doing this without writing a full-blown SQL parser is inherently flawed. Since we don't want to write an SQL parser, we are removing this functionality. From now on, you must explicitly tell Active Record when you are referencing a table from a string:

Post.includes(:comments).where("comments.title = 'foo'").references(:comments)

To add a bit of context to M.Ali's Answer you can convert a string to a uniqueidentifier using the following code

   SELECT CONVERT(uniqueidentifier,'DF215E10-8BD4-4401-B2DC-99BB03135F2E')

If that doesn't work check to make sure you have entered a valid GUID

In my case eclipse was using an old settings.xml file.

To avoid error on null value you can use this code:

{{ game.gameDate ? game.gameDate|date('Y-m-d H:i:s') : '' }}

Late answer here, but for anyone who needs to write special characters to a single line who find dbenham's answer to be about 80 lines too long and whose scripts may break (perhaps due to user-input) under the limitations of simply using set /p, it's probably easiest to just to pair your .bat or .cmd with a compiled C++ or C-language executable and then just cout or printf the characters. This will also allow you to easily write multiple times to one line if you're showing a sort of progress bar or something using characters, as OP apparently was.

@Autowired annotation is defined in the Spring framework.

@Inject annotation is a standard annotation, which is defined in the standard "Dependency Injection for Java" (JSR-330). Spring (since the version 3.0) supports the generalized model of dependency injection which is defined in the standard JSR-330. (Google Guice frameworks and Picocontainer framework also support this model).

With @Inject can be injected the reference to the implementation of the Provider interface, which allows injecting the deferred references.

Annotations @Inject and @Autowired- is almost complete analogies. As well as @Autowired annotation, @Inject annotation can be used for automatic binding properties, methods, and constructors.

In contrast to @Autowired annotation, @Inject annotation has no required attribute. Therefore, if the dependencies will not be found - will be thrown an exception.

There are also differences in the clarifications of the binding properties. If there is ambiguity in the choice of components for the injection the @Named qualifier should be added. In a similar situation for @Autowired annotation will be added @Qualifier qualifier (JSR-330 defines it's own @Qualifier annotation and via this qualifier annotation @Named is defined).

A statement contains a keyword.

An expression does not contain a keyword.

print "hello" is statement, because print is a keyword.

"hello" is an expression, but list compression is against this.

The following is an expression statement, and it is true without list comprehension:

(x*2 for x in range(10))

" Hello " , " This " , "is ", "Sorting ", "Example"

First of all you provided spaces in " Hello " and " This ", spaces have a lower value than alphabetic characters in Unicode, so it gets printed first. (The rest of the characters were sorted alphabetically).

Now upper case letters have a lower value than lower case letter in Unicode, so "Example" and "Sorting" gets printed, then at last "is " which has the highest value.

To be more international (and not only US colored ;-) ) just replace in the code above by

-(NSNumber *) getNumber
{
  NSString* localeIdentifier = [[NSLocale autoupdatingCurrentLocale] localeIdentifier];
  NSLocale *l_en = [[NSLocale alloc] initWithLocaleIdentifier: localeIdentifier] ;
  return [self getNumberWithLocale: [l_en autorelease] ];
}

use Illuminate\Http\Request;
public function store(Request $request){
   dd($request->all());
}

is same in context saying

use Request;
public function store(){
   dd(Request::all());
}

That way you haven't installed pip, you installed just the easy_install i.e. setuptools.

First you should remove all the packages you installed with easy_install using (see uninstall):

easy_install -m PackageName

This includes pip if you installed it using easy_install pip.

After this you remove the setuptools following the instructions from here:

If setuptools package is found in your global site-packages directory, you may safely remove the following file/directory:

setuptools-*.egg

If setuptools is installed in some other location such as the user site directory (eg: ~/.local, ~/Library/Python or %APPDATA%), then you may safely remove the following files:

pkg_resources.py
easy_install.py
setuptools/
setuptools-*.egg-info/

display: none;

This should make the element disappear and not take up any space.

Press Ctrl + H, should bring up the search that will include options to search via project, directory, etc.

Ctrl + Alt + G can be used to find selected text across a workspace in eclipse.

It's nice to see code and know what it does. If I see std::cout I know that's the cout stream of the std library. If I see cout then I don't know. It could be the cout stream of the std library. Or there could be an int cout = 0; ten lines higher in the same function. Or a static variable named cout in that file. It could be anything.

Now take a million line code base, which isn't particularly big, and you're searching for a bug, which means you know there is one line in this one million lines that doesn't do what it is supposed to do. cout << 1; could read a static int named cout, shift it to the left by one bit, and throw away the result. Looking for a bug, I'd have to check that. Can you see how I really really prefer to see std::cout?

It's one of these things that seem a really good idea if you are a teacher and never had to write and maintain any code for a living. I love seeing code where (1) I know what it does; and, (2) I'm confident that the person writing it knew what it does.

We can also use regular expression (/^([\w.-]+)@([\w-]+)((.(\w){2,3})+)$/i) to validate email address format is correct or not.

var emailRegex = new RegExp(/^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$/i);
 var valid = emailRegex.test(emailAddress);
  if (!valid) {
    alert("Invalid e-mail address");
    return false;
  } else
    return true;

There are a number of different $_SERVER (docs) properties that return information about the current page, but my preferred method is to use $_SERVER['HTTP_HOST']:

header("Location: " . "http://" . $_SERVER['HTTP_HOST'] . $location);

where $location is the path after the domain, starting with /.

I have created a Generic AsyncTask Listener which get result from AsycTask seperate class and give it to CallingActivity using Interface Callback.

new GenericAsyncTask(context,new AsyncTaskCompleteListener()
        {
             public void onTaskComplete(String response) 
             {
                 // do your work. 
             }
        }).execute();

Interface

interface AsyncTaskCompleteListener<T> {
   public void onTaskComplete(T result);
}

GenericAsyncTask

class GenericAsyncTask extends AsyncTask<String, Void, String> 
{
    private AsyncTaskCompleteListener<String> callback;

    public A(Context context, AsyncTaskCompleteListener<String> cb) {
        this.context = context;
        this.callback = cb;
    }

    protected void onPostExecute(String result) {
       finalResult = result;
       callback.onTaskComplete(result);
   }  
}

I've occasionally thought that it might serve a purpose to add a layer of security by obscuring the back-end interpreter through a remapping of .php or whatever to .aspx or whatever so that any potential hacker would be sent down the wrong path, at least for a while. I never bothered to try it and I don't do a lot of webserver work any more so I'm unlikely to.

However, I'd be interested in the perspective of an experienced server admin on that notion.

Take a look at boost::assign.

This is the activity the tools UI editor uses to render your layout preview. It is documented here:

This attribute declares which activity this layout is associated with by default. This enables features in the editor or layout preview that require knowledge of the activity, such as what the layout theme should be in the preview and where to insert onClick handlers when you make those from a quickfix

If you use Eclipse as your IDE I would recommend the excellent eclipse plugin memory analyzer

Another option is to use JVisualVM, it can read (and create) heap dumps as well, and is shipped with every JDK. You can find it in the bin directory of your JDK.

this is very simple approach to concatenate or append the character

       StringBuilder desc = new StringBuilder(); 
       String Description="this is my land"; 
       desc=desc.append(Description.charAt(i));

The error message is actually correct if not obvious. It says that your DOCTYPE must have a SYSTEM identifier. I assume yours only has a public identifier.

You'll get the error with (for instance):

<!DOCTYPE persistence PUBLIC
    "http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

You won't with:

<!DOCTYPE persistence PUBLIC
    "http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" "">

Notice "" at the end in the second one -- that's the system identifier. The error message is confusing: it should say that you need a system identifier, not that you need a space between the publicId and the (non-existent) systemId.

By the way, an empty system identifier might not be ideal, but it might be enough to get you moving.

You may want to consider using <<<

e.g.

<<<VARIABLE
this is some
random text
that I'm typing 
here and I will end it with the 
same word I started it with
VARIABLE

Btw - Some Coding environments don't know how to handle the above syntax.

You can use the spread operator to convert Map.keys() iterator in an Array.

let myMap = new Map().set('a', 1).set('b', 2).set(983, true)_x000D_
let keys = [...myMap.keys()]_x000D_
console.log(keys)

You should be able to set your credentials like this:

git remote set-url origin https://<USERNAME>:<PASSWORD>@bitbucket.org/path/to/repo.git

You can get the remote url like this:

git config --get remote.origin.url

you have to import spring-boot-starter-data-jpa as dependeny if you use spring boot

It's possible that this might work, but it might prove to be a bit of a nuisance at some point in the future (if not immediately).

<style> 
tbody td span {display: inline-block;
               width: 10em; /* this is the nuisance part, as you'll have to define a particular width, and I assume -without testing- that any percent widths would be relative to the containing `<td>`, not the `<tr>` or `<table>` */
               overflow: hidden; 
               white-space: nowrap; }

</style>

...

<table>

<thead>...</thead>
<tfoot>...</tfoot>

<tbody>

<tr>

<td><span title="some text">some text</span></td> <td><span title="some more text">some more text</span></td> <td><span title="yet more text">yet more text</span></td>

</tr>

</tbody>

</table>

The rationale for the span is that, as pointed out by others, a <td> will typically expand to accommodate the content, whereas a <span> can be given -and expected to keep- a set width; the overflow: hidden is intended to, but might not, hide what would otherwise cause the <td> to expand.

I'd recommend using the title property of the span to show the text that's present (or clipped) in the visual cell, so that the text's still available (and if you don't want/need people to see it, then why have it in the first place, I guess...).

Also, if you define a width for the td {...} the td will expand (or potentially contract, but I doubt it) to fill its implied width (as I see it this seems to be table-width/number-of-cells), a specified table-width doesn't seem to create the same issue.

The downside is additional markup used for presentation.

This is an ancient question, but why is everyone overlooking the simplest regexp-based solution? Normal regexp quantifiers are greedy, people! If you want to find the last instance of a pattern, just stick .* in front of it. Here's how:

$text = "The quick brown fox, fox, fox, fox, jumps over etc.";
$fixed = preg_replace("((.*)fox)", "$1DUCK", $text);
print($fixed);

This will replace the last instance of "fox" to "DUCK", like it's supposed to, and print:

When a dictionary is enumerated, it will yield KeyValuePair<TKey,TValue> objects... so you just need to specify "Value" and "Key" for DataTextField and DataValueField respectively, to select the Value/Key properties.

Thanks to Joe's comment, I reread the question to get these the right way round. Normally I'd expect the "key" in the dictionary to be the text that's displayed, and the "value" to be the value fetched. Your sample code uses them the other way round though. Unless you really need them to be this way, you might want to consider writing your code as:

list.Add(cul.DisplayName, cod);

(And then changing the binding to use "Key" for DataTextField and "Value" for DataValueField, of course.)

In fact, I'd suggest that as it seems you really do want a list rather than a dictionary, you might want to reconsider using a dictionary in the first place. You could just use a List<KeyValuePair<string, string>>:

string[] languageCodsList = service.LanguagesAvailable();
var list = new List<KeyValuePair<string, string>>();

foreach (string cod in languageCodsList)
{
    CultureInfo cul = new CultureInfo(cod);
    list.Add(new KeyValuePair<string, string>(cul.DisplayName, cod));
}

Alternatively, use a list of plain CultureInfo values. LINQ makes this really easy:

var cultures = service.LanguagesAvailable()
                      .Select(language => new CultureInfo(language));
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();

If you're not using LINQ, you can still use a normal foreach loop:

List<CultureInfo> cultures = new List<CultureInfo>();
foreach (string cod in service.LanguagesAvailable())
{
    cultures.Add(new CultureInfo(cod));
}
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();

I had this exception in the case of a test for checking some actual accessed URLs by users.

And the URLs are sometime contains an illegal-character and hang by this error.

So I make a function to encode only the characters in the URL string like this.

String encodeIllegalChar(String uriStr,String enc)
  throws URISyntaxException,UnsupportedEncodingException {
  String _uriStr = uriStr;
  int retryCount = 17;
  while(true){
     try{
       new URI(_uriStr);
       break;
     }catch(URISyntaxException e){
       String reason = e.getReason();
       if(reason == null ||
         !(
          reason.contains("in path") ||
          reason.contains("in query") ||
          reason.contains("in fragment")
         )
       ){
         throw e;
       }
       if(0 > retryCount--){
         throw e;
       }
       String input = e.getInput();
       int idx = e.getIndex();
       String illChar = String.valueOf(input.charAt(idx));
       _uriStr = input.replace(illChar,URLEncoder.encode(illChar,enc));
     }
  }
  return _uriStr;
}

test:

String q =  "\\'|&`^\"<>)(}{][";
String url = "http://test.com/?q=" + q + "#" + q;
String eic = encodeIllegalChar(url,'UTF-8');
System.out.println(String.format("  original:%s",url));
System.out.println(String.format("   encoded:%s",eic));
System.out.println(String.format("   uri-obj:%s",new URI(eic)));
System.out.println(String.format("re-decoded:%s",URLDecoder.decode(eic)));

.so files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.

.a files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar command -- a predecessor of tar that's now just used for making libraries) of the original .o object files.

.la files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?

Static and dynamic libraries each have pros and cons.

Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.

Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.

Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.

Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.

Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.

Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.

Dynamic libraries are especially useful for system libraries, like libc. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.

You can use the backtick operator:

& "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" `
    -verb:sync `
    -source:contentPath="c:\workspace\xxx\master\Build\_PublishedWebsites\xxx.Web" `
    -dest:contentPath="c:\websites\xxx\wwwroot\,computerName=192.168.1.1,username=administrator,password=xxx"

That's still a little too long for my taste, so I'd use some well-named variables:

$msdeployPath = "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe"
$verbArg = '-verb:sync'
$sourceArg = '-source:contentPath="c:\workspace\xxx\master\Build\_PublishedWebsites\xxx.Web"'
$destArg = '-dest:contentPath="c:\websites\xxx\wwwroot\,computerName=192.168.1.1,username=administrator,password=xxx"'

& $msdeployPath $verbArg $sourceArg $destArg

If it's not the Home edition of XP, you can use \\servername\c$

Note that you need to be an Administrator on the local machine, as the share permissions are locked down

After installing conda in Linux if you are trying to create env just type bash and hit Enter later you can create env

As mentioned by @Rafael Almeida, the problem you are having is caused by an untrusted SSL certificate. In my case, the SSL certificate was untrusted by my server. To get around this without compromising security, I downloaded the certificate, and installed it on the server (by simply double clicking on the .crt file and then Install Certificate...).

From this post:

To get the entire PC CPU and Memory usage:

using System.Diagnostics;

Then declare globally:

private PerformanceCounter theCPUCounter = 
   new PerformanceCounter("Processor", "% Processor Time", "_Total"); 

Then to get the CPU time, simply call the NextValue() method:

this.theCPUCounter.NextValue();

This will get you the CPU usage

As for memory usage, same thing applies I believe:

private PerformanceCounter theMemCounter = 
   new PerformanceCounter("Memory", "Available MBytes");

Then to get the memory usage, simply call the NextValue() method:

this.theMemCounter.NextValue();

For a specific process CPU and Memory usage:

private PerformanceCounter theCPUCounter = 
   new PerformanceCounter("Process", "% Processor Time",              
   Process.GetCurrentProcess().ProcessName);

where Process.GetCurrentProcess().ProcessName is the process name you wish to get the information about.

private PerformanceCounter theMemCounter = 
   new PerformanceCounter("Process", "Working Set",
   Process.GetCurrentProcess().ProcessName);

where Process.GetCurrentProcess().ProcessName is the process name you wish to get the information about.

Note that Working Set may not be sufficient in its own right to determine the process' memory footprint -- see What is private bytes, virtual bytes, working set?

To retrieve all Categories, see Walkthrough: Retrieving Categories and Counters

The difference between Processor\% Processor Time and Process\% Processor Time is Processor is from the PC itself and Process is per individual process. So the processor time of the processor would be usage on the PC. Processor time of a process would be the specified processes usage. For full description of category names: Performance Monitor Counters

An alternative to using the Performance Counter

Use System.Diagnostics.Process.TotalProcessorTime and System.Diagnostics.ProcessThread.TotalProcessorTime properties to calculate your processor usage as this article describes.

just a simple answer:

    public static int CountChars(string myString, char myChar)
    {
        int count = 0;
        for (int i = 0; i < myString.Length; i++)
        {
            if (myString[i] == myChar) ++count;
        }
        return count;
    }

If one of the inserts fail, or any part of the command fails, does SQL server roll back the transaction?

No, it does not.

If it does not rollback, do I have to send a second command to roll it back?

Sure, you should issue ROLLBACK instead of COMMIT.

If you want to decide whether to commit or rollback the transaction, you should remove the COMMIT sentence out of the statement, check the results of the inserts and then issue either COMMIT or ROLLBACK depending on the results of the check.

With PowerShell 5.1 in Windows 10 you can use:

Get-SmbMapping | Remove-SmbMapping -Confirm:$false

to install php5-curl under opensuse:

sudo yast2

->software ->software management ->search for curl ->check php5-curl case and accept.

after installation you need to restart apache server

iOS 8 users and above, please include this in App delegate to make it work.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)])
    {
        [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];
    }

    return YES;
}

And then adding this lines of code would help,

- (void)applicationDidEnterBackground:(UIApplication *)application
{
    UILocalNotification *notification = [[UILocalNotification alloc]init];
    notification.repeatInterval = NSDayCalendarUnit;
    [notification setAlertBody:@"Hello world"];
    [notification setFireDate:[NSDate dateWithTimeIntervalSinceNow:1]];
    [notification setTimeZone:[NSTimeZone  defaultTimeZone]];
    [application setScheduledLocalNotifications:[NSArray arrayWithObject:notification]];

}

The first value is the precision and the second is the scale, so 18,0 is essentially 18 digits with 0 digits after the decimal place. If you had 18,2 for example, you would have 18 digits, two of which would come after the decimal...

example of 18,2: 1234567890123456.12

There is no functional difference between numeric and decimal, other that the name and I think I recall that numeric came first, as in an earlier version.

And to answer, "can I add (-10) in that column?" - Yes, you can.

Test this query.

SELECT *,DATE(chat_reg_date) AS is_date,TIME(chat_reg_time) AS is_time FROM chat WHERE chat_inbox_key='$chat_key' 
                         ORDER BY is_date DESC, is_time DESC

I guess the simplest solution would be:

mProgressBar.setScaleY(3f);

The following would need extensive customisation to format the table correctly, but the bones of it works:

The output looks like this:

To select all anchors with the data attribute data-customerID==22, you should include the a to limit the scope of the search to only that element type. Doing data attribute searches in a large loop or at high frequency when there are many elements on the page can cause performance issues.

$('a[data-customerID="22"]');

In essence all you need to do are the following:

server = $1
branch = $2
git push $server $branch
ssh <username>@$server "cd /path/to/www; git pull"

I have those lines in my application as an executable called deploy.

so when I want to do a deploy I type ./deploy myserver mybranch.

I found after trying lots of convoluted examples that very simple approach worked for me.

I just wanted to take a dump of a db from local and import it on a remote instance:

on the local machine:

mongodump -d databasename

then I scp'd my dump to my server machine:

scp -r dump [email protected]:~

then from the parent dir of the dump simply:

mongorestore 

and that imported the database.

assuming mongodb service is running of course.

You should use strftime static method from datetime class from datetime module. Try:

import datetime
dtDate = datetime.datetime.strptime("07/27/2012", "%m/%d/%Y")

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

tl;dr

You asked:

I was looking for a one-liner like:

Ask and ye shall receive. Convert from terrible legacy class Date to its modern replacement, Instant.

myJavaUtilDate.toInstant().toString()

java.time

In Java 8 and later we have the new java.time package built in (Tutorial). Inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project.

The best solution is to sort your date-time objects rather than strings. But if you must work in strings, read on.

An Instant represents a moment on the timeline, basically in UTC (see class doc for precise details). The toString implementation uses the DateTimeFormatter.ISO_INSTANT format by default. This format includes zero, three, six or nine digits digits as needed to display fraction of a second up to nanosecond precision.

String output = Instant.now().toString(); // Example: '2015-12-03T10:15:30.120Z'

If you must interoperate with the old Date class, convert to/from java.time via new methods added to the old classes. Example: Date::toInstant.

myJavaUtilDate.toInstant().toString()

You may want to use an alternate formatter if you need a consistent number of digits in the fractional second or if you need no fractional second.

Another route if you want to truncate fractions of a second is to use ZonedDateTime instead of Instant, calling its method to change the fraction to zero.

Note that we must specify a time zone for ZonedDateTime (thus the name). In our case that means UTC. The subclass of ZoneID, ZoneOffset, holds a convenient constant for UTC. If we omit the time zone, the JVM’s current default time zone is implicitly applied.

String output = ZonedDateTime.now( ZoneOffset.UTC ).withNano( 0 ).toString();  // Example: 2015-08-27T19:28:58Z

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

Joda-Time

UPDATE: The Joda -Time project is now in maintenance mode, with the team advising migration to the java.time classes.

I was looking for a one-liner

Easy if using the Joda-Time 2.3 library. ISO 8601 is the default formatting.

Time Zone

In the code example below, note that I am specifying a time zone rather than depending on the default time zone. In this case, I'm specifying UTC per your question. The Z on the end, spoken as "Zulu", means no time zone offset from UTC.

Example Code

// import org.joda.time.*;

String output = new DateTime( DateTimeZone.UTC );

Output…

2013-12-12T18:29:50.588Z

You can use jQuery to select the jQuery object for that element. Then, get the underlying DOM element and call its click() method.

By id:

$("#my-link").each(function (index) { $(this).get(0).click() });

Or use jQuery to click a bunch of links by CSS class:

$(".my-link-class").each(function (index) { $(this).get(0).click() });

First, you need to convert your string to NSDate with its format. Then, you change the dateFormatter to your simple format and convert it back to a String.

Swift 3

let dateString = "Thu, 22 Oct 2015 07:45:17 +0000"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEE, dd MMM yyyy hh:mm:ss +zzzz"
dateFormatter.locale = Locale.init(identifier: "en_GB")

let dateObj = dateFormatter.date(from: dateString)

dateFormatter.dateFormat = "MM-dd-yyyy"
print("Dateobj: \(dateFormatter.string(from: dateObj!))")

The printed result is: Dateobj: 10-22-2015

The most efficient way is to take input make the logic and run

so the code is like this to make your own space maker

need = input("Write a string:- ")
result = ''
for character in need:
   result = result + character + ' '
print(result)    # to rid of space after O

but if you want to use what python give then use this code

need2 = input("Write a string:- ")

print(" ".join(need2))

I had to use the "=" binding instead of "&" because that was not working. Strange behavior.

In addition to the solution you accepted, you could also implement the special __lt__() ("less than") method on the class. The sort() method (and the sorted() function) will then be able to compare the objects, and thereby sort them. This works best when you will only ever sort them on this attribute, however.

class Foo(object):

     def __init__(self, score):
         self.score = score

     def __lt__(self, other):
         return self.score < other.score

l = [Foo(3), Foo(1), Foo(2)]
l.sort()

As simple as joining lists in python itself.

ansible -m debug -a msg="{{ '-'.join(('list', 'joined', 'together')) }}" localhost

localhost | SUCCESS => {
  "msg": "list-joined-together" }

Works the same way using variables:

ansible -m debug -a msg="{{ '-'.join((var1, var2, var3)) }}" localhost

Date and time formats are well described below

SimpleDateFormat (Java Platform SE 7) - Date and Time Patterns

There could be n Number of formats you can possibly make. ex - dd/MM/yyyy or YYYY-'W'ww-u or you can mix and match the letters to achieve your required pattern. Pattern letters are as follow.

• G - Era designator (AD)
• y - Year (1996; 96)
• Y - Week Year (2009; 09)
• M - Month in year (July; Jul; 07)
• w - Week in year (27)
• W - Week in month (2)
• D - Day in year (189)
• d - Day in month (10)
• F - Day of week in month (2)
• E - Day name in week (Tuesday; Tue)
• u - Day number of week (1 = Monday, ..., 7 = Sunday)
• a - AM/PM marker
• H - Hour in day (0-23)
• k - Hour in day (1-24)
• K - Hour in am/pm (0-11)
• h - Hour in am/pm (1-12)
• m - Minute in hour (30)
• s - Second in minute (55)
• S - Millisecond (978)
• z - General time zone (Pacific Standard Time; PST; GMT-08:00)
• Z - RFC 822 time zone (-0800)
• X - ISO 8601 time zone (-08; -0800; -08:00)

To parse:

2000-01-23T04:56:07.000+0000

Use: new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");

Hit this error trying to run terraform/terragrunt (Single go binary).

Using which terragrunt to find where executable was, got strange error when running it in local dir or with full path

bash: ./terragrunt: No such file or directory

Problem was that there was two installations of terragrunt, used brew uninstall terragrunt to remove one fixed it.

After removing the one, which terragrunt showed the new path /usr/bin/terragrunt everything worked fine.

You have to give a separate id to the label too.

<label for="foo" id="foo_label">text</label>

#foo_label {display: none;}

Or hide the whole row

<tr id="foo_row">/***/</tr>

#foo_row {display: none;}

1. Click somewhere on the chart to select it.

2. You should now see 3 new tabs appear at the top of the screen called "Design", "Layout" and "Format".

3. Click on the "Design" tab.

4. There will be a button called "Switch Row/Column" within the "data" group, click it.

You can use https://appery.io/ It is the same phonegap but in very convinient wrapper

You also can do type switches:

switch v := myInterface.(type) {
case int:
    // v is an int here, so e.g. v + 1 is possible.
    fmt.Printf("Integer: %v", v)
case float64:
    // v is a float64 here, so e.g. v + 1.0 is possible.
    fmt.Printf("Float64: %v", v)
case string:
    // v is a string here, so e.g. v + " Yeah!" is possible.
    fmt.Printf("String: %v", v)
default:
    // And here I'm feeling dumb. ;)
    fmt.Printf("I don't know, ask stackoverflow.")
}

In my case, I was creating an HttpClient inside a method that actually did the service call. Something like:

public void DoServiceCall() {
  var client = new HttpClient();
  await client.PostAsync();
}

In an Azure worker role, after repeatedly calling this method (without disposing the HttpClient), it would eventually fail with SocketException (connection attempt failed).

I made the HttpClient an instance variable (disposing it at the class level) and the issue went away. So I would say, yes, dispose the HttpClient, assuming its safe (you don't have outstanding async calls) to do so.

You can't use UIImagePickerController, but you can use a custom image picker. I think ELCImagePickerController is the best option, but here are some other libraries you could use:

Objective-C
1. ELCImagePickerController
2. WSAssetPickerController
3. QBImagePickerController
4. ZCImagePickerController
5. CTAssetsPickerController
6. AGImagePickerController
7. UzysAssetsPickerController

Thanx to @androidbloke,
I have added some library that I know for multiple image picker in swift.
Will update list as I find new ones.
Thank You.

You can use the str.split method.

>>> my_string = 'A,B,C,D,E'
>>> my_list = my_string.split(",")
>>> print my_list
['A', 'B', 'C', 'D', 'E']

If you want to convert it to a tuple, just

>>> print tuple(my_list)
('A', 'B', 'C', 'D', 'E')

If you are looking to append to a list, try this:

>>> my_list.append('F')
>>> print my_list
['A', 'B', 'C', 'D', 'E', 'F']

"creating an instance of a class" how about, "you are taking a class and making a new variable of that class that WILL change depending on an input that changes"

Class in the library called Nacho

variable Libre to hold the "instance" that will change

Nacho Libre = new Nacho(Variable, Scanner Input, or whatever goes here, This is the place that accepts the changes then puts the value in "Libre" on the left side of the equals sign (you know "Nacho Libre = new Nacho(Scanner.in)" "Nacho Libre" is on the left of the = (that's not tech talk, that's my way of explaining it)

I think that is better than saying "instance of type" or "instance of class". Really the point is it just needs to be detailed out more.... "instance of type or class" is not good enough for the beginner..... wow, its like a tongue twister and your brain cannot focus on tongue twisters very well.... that "instance" word is very annoying and the mere sound of it drives me nuts.... it begs for more detail.....it begs to be broken down better. I had to google what "instance" meant just to get my bearings straight..... try saying "instance of class" to your grandma.... yikes!

If you don't want to pollute your source code (after all this warning presents only with Microsoft compiler), add _CRT_SECURE_NO_WARNINGS symbol to your project settings via "Project"->"Properties"->"Configuration properties"->"C/C++"->"Preprocessor"->"Preprocessor definitions".

Also you can define it just before you include a header file which generates this warning. You should add something like this

#ifdef _MSC_VER
#define _CRT_SECURE_NO_WARNINGS
#endif

And just a small remark, make sure you understand what this warning stands for, and maybe, if you don't intend to use other compilers than MSVC, consider using safer version of functions i.e. strcpy_s instead of strcpy.

And it works fine, but I am having the concern whether the scripts added to be executed in this manner are being executed asynchronously. If yes then it can happen that work.js runs even before jQuery (or other libraries which I may add in future).

That shouldn't really be a concern: you queue up scripts to be executed in a certain JS context, and that context can't have a race condition as it's single-threaded.

However, the proper way to eliminate this concern is to chain the calls:

chrome.browserAction.onClicked.addListener(function (tab) {
    chrome.tabs.executeScript({
        file: 'thirdParty/jquery-2.0.3.js'
    }, function() {
        // Guaranteed to execute only after the previous script returns
        chrome.tabs.executeScript({
            file: 'work.js'
        });
    });
});

Or, generalized:

function injectScripts(scripts, callback) {
  if(scripts.length) {
    var script = scripts.shift();
    chrome.tabs.executeScript({file: script}, function() {
      if(chrome.runtime.lastError && typeof callback === "function") {
        callback(false); // Injection failed
      }
      injectScripts(scripts, callback);
    });
  } else {
    if(typeof callback === "function") {
      callback(true);
    }
  }
}

injectScripts(["thirdParty/jquery-2.0.3.js", "work.js"], doSomethingElse);

Or, promisified (and brought more in line with the proper signature):

function injectScript(tabId, injectDetails) {
  return new Promise((resolve, reject) => {
    chrome.tabs.executeScript(tabId, injectDetails, (data) => {
      if (chrome.runtime.lastError) {
        reject(chrome.runtime.lastError.message);
      } else {
        resolve(data);
      }
    });
  });
}

injectScript(null, {file: "thirdParty/jquery-2.0.3.js"}).then(
  () => injectScript(null, {file: "work.js"})
).then(
  () => doSomethingElse
).catch(
  (error) => console.error(error)
);

Or, why the heck not, async/await-ed for even clearer syntax:

function injectScript(tabId, injectDetails) {
  return new Promise((resolve, reject) => {
    chrome.tabs.executeScript(tabId, injectDetails, (data) => {
      if (chrome.runtime.lastError) {
        reject(chrome.runtime.lastError.message);
      } else {
        resolve(data);
      }
    });
  });
}

try {
  await injectScript(null, {file: "thirdParty/jquery-2.0.3.js"});
  await injectScript(null, {file: "work.js"});
  doSomethingElse();
} catch (err) {
  console.error(err);
}

Note, in Firefox you can just use browser.tabs.executeScript as it will return a Promise.

Each character is used to represent 6 bits (log2(64) = 6).

Therefore 4 chars are used to represent 4 * 6 = 24 bits = 3 bytes.

So you need 4*(n/3) chars to represent n bytes, and this needs to be rounded up to a multiple of 4.

The number of unused padding chars resulting from the rounding up to a multiple of 4 will obviously be 0, 1, 2 or 3.

To avoid this sort of trouble, you can use replace (which takes a plain string) instead of replaceAll (which takes a regular expression). You will still need to escape backslashes, but not in the wild ways required with regular expressions.

Ah, that would be because RegExp is not jQuery. :)

Try this page. jQuery.attr doesn't return a String so that would certainly cause in this regard. Fortunately I believe you can just use .text() to return the String representation.

Something like:

$("li").val("title").search(/sometext/i));

The message from Linus Torvalds may answer your question:

Modify/edit old commit messages

Short answer: you can not (if pushed).

extract (Linus refers to BitKeeper as BK):

Side note, just out of historical interest: in BK you could.

And if you're used to it (like I was) it was really quite practical. I would apply a patch-bomb from Andrew, notice something was wrong, and just edit it before pushing it out.

I could have done the same with git. It would have been easy enough to make just the commit message not be part of the name, and still guarantee that the history was untouched, and allow the "fix up comments later" thing.

But I didn't.

Part of it is purely "internal consistency". Git is simply a cleaner system thanks to everything being SHA1-protected, and all objects being treated the same, regardless of object type. Yeah, there are four different kinds of objects, and they are all really different, and they can't be used in the same way, but at the same time, even if their encoding might be different on disk, conceptually they all work exactly the same.

But internal consistency isn't really an excuse for being inflexible, and clearly it would be very flexible if we could just fix up mistakes after they happen. So that's not a really strong argument.

The real reason git doesn't allow you to change the commit message ends up being very simple: that way, you can trust the messages. If you allowed people to change them afterwards, the messages are inherently not very trustworthy.

To be complete, you could rewrite your local commit history in order to reflect what you want, as suggested by sykora (with some rebase and reset --hard, gasp!)

However, once you publish your revised history again (with a git push origin +master:master, the + sign forcing the push to occur, even if it doesn't result in a "fast-forward" commit)... you might get into some trouble.

Extract from this other SO question:

I actually once pushed with --force to git.git repository and got scolded by Linus BIG TIME. It will create a lot of problems for other people. A simple answer is "don't do it".

I feel a little stupid, but my issue was that I was running docker-compose, and my Dockerfile was in a ./deploy subdirectory. My ADD reference needed to be relative to the root of the project, not the Dockerfile.

Changed: ADD ./file.tar.gz /etc/folder/ to: ADD ./deploy/file.tar.gz /etc/folder/

Anyhow, thought I'd post in case someone ran into the same issue.

Try this:

sed "s/aaa=.*/aaa=xxx/g"

i post something into an iframe then read back the contents of the iframe with json parse...so sometimes it's not a json string

Try this:

if(response) {
    try {
        a = JSON.parse(response);
    } catch(e) {
        alert(e); // error in the above string (in this case, yes)!
    }
}

We, the Javascript lovers, don't have to use Ruby (Jekyll or Octopress) to generate static pages in Github pages, we can use Node.js and Harp, for example:

These are the steps. Abstract:

1. Create a New Repository

2. Clone the Repository

   git clone https://github.com/your-github-user-name/your-github-user-name.github.io.git
   

3. Initialize a Harp app (locally):

   harp init _harp
   

make sure to name the folder with an underscore at the beginning; when you deploy to GitHub Pages, you don’t want your source files to be served.

4. Compile your Harp app

   harp compile _harp ./
   

5. Deploy to Gihub

   git add -A
   git commit -a -m "First Harp + Pages commit"
   git push origin master
   

And this is a cool tutorial with details about nice stuff like layouts, partials, Jade and Less.

I've been using jquery ui timepicker

This works fine for me. It allows value to be entered even after focus changed and retrieved back. For example: 123.00, 12.12, 0.01, etc..

1.Integer.parseInt(getString(R.string.valuelength)) Specifies the length of the input digits.Values accessed from string.xml file.It is quiet easy to change values. 2.Integer.parseInt(getString(R.string.valuedecimal)), this is for decimal places max limit.

private InputFilter[] valDecimalPlaces;
private ArrayList<EditText> edittextArray;

valDecimalPlaces = new InputFilter[] { new DecimalDigitsInputFilterNew(
    Integer.parseInt(getString(R.string.valuelength)),
    Integer.parseInt(getString(R.string.valuedecimal))) 
};

Array of EditText values that allows to perform action.

for (EditText etDecimalPlace : edittextArray) {
            etDecimalPlace.setFilters(valDecimalPlaces);

I just used array of values that contain multiple edittext Next DecimalDigitsInputFilterNew.class file.

import android.text.InputFilter;
import android.text.Spanned;

public class DecimalDigitsInputFilterNew implements InputFilter {

    private final int decimalDigits;
    private final int before;

    public DecimalDigitsInputFilterNew(int before ,int decimalDigits) {
        this.decimalDigits = decimalDigits;
        this.before = before;
    }

    @Override
    public CharSequence filter(CharSequence source, int start, int end,
        Spanned dest, int dstart, int dend) {
        StringBuilder builder = new StringBuilder(dest);
        builder.replace(dstart, dend, source
              .subSequence(start, end).toString());
        if (!builder.toString().matches("(([0-9]{1})([0-9]{0,"+(before-1)+"})?)?(\\.[0-9]{0,"+decimalDigits+"})?")) {
             if(source.length()==0)
                  return dest.subSequence(dstart, dend);
             return "";
        }
        return null;
    }
}

For Show Current Date and Time on Textview

    /// For Show Date
    String currentDateString = DateFormat.getDateInstance().format(new Date());
    // textView is the TextView view that should display it
    textViewdate.setText(currentDateString);
    /// For Show Time

The CSS margin property can be used to affect all paragraphs:

p {
  margin: XXXem;
}

Replace XXX with your desired value; for no space at all use:

p {
  margin: 0em;
}

There isn't a "pure python" way to do this because some other process would have to launch python in order to run your solution. Every platform will have one or twenty different ways to launch processes and monitor their progress. On unix platforms, cron is the old standard. On Mac OS X there is also launchd, which combines cron-like launching with watchdog functionality that can keep your process alive if that's what you want. Once python is running, then you can use the sched module to schedule tasks.

If you look up the help page, one of the arguments to lapply is the mysterious .... When we look at the Arguments section of the help page, we find the following line:

...: optional arguments to ‘FUN’.

So all you have to do is include your other argument in the lapply call as an argument, like so:

lapply(input, myfun, arg1=6)

and lapply, recognizing that arg1 is not an argument it knows what to do with, will automatically pass it on to myfun. All the other apply functions can do the same thing.

An addendum: You can use ... when you're writing your own functions, too. For example, say you write a function that calls plot at some point, and you want to be able to change the plot parameters from your function call. You could include each parameter as an argument in your function, but that's annoying. Instead you can use ... (as an argument to both your function and the call to plot within it), and have any argument that your function doesn't recognize be automatically passed on to plot.

A third option, for a pipelined one-liner is to nest the -replaces:

PS> ("ABC" -replace "B","C") -replace "C","D"
ADD

And:

PS> ("ABC" -replace "C","D") -replace "B","C"
ACD

This preserves execution order, is easy to read, and fits neatly into a pipeline. I prefer to use parentheses for explicit control, self-documentation, etc. It works without them, but how far do you trust that?

-Replace is a Comparison Operator, which accepts an object and returns a presumably modified object. This is why you can stack or nest them as shown above.

Below code utilizes System.Drawing.Bitmap to load the image.

using System.Drawing;
using System.Drawing.Imaging;

public IActionResult Get()
{
    string filename = "Image/test.jpg";
    var bitmap = new Bitmap(filename);

    var ms = new System.IO.MemoryStream();
    bitmap.Save(ms, ImageFormat.Jpeg);
    ms.Position = 0;
    return new FileStreamResult(ms, "image/jpeg");
}

@CommonsWare's answer doesn't not actually work. I found that this is working properly :

map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(-33.88,151.21), 15));

Datetimes are comparable; so you can use max(datetimes_list) and min(datetimes_list)

This worked for me - if you have to log in Application_Start, do it before you modify the context. You will get a log entry, just with no source, like:

2019-03-12 09:35:43,659 INFO (null) - Application Started

I generally log both the Application_Start and Session_Start, so I see more detail in the next message

2019-03-12 09:35:45,064 INFO ~/Leads/Leads.aspx - Session Started (Local)

        protected void Application_Start(object sender, EventArgs e)
        {
            log4net.Config.XmlConfigurator.Configure();
            log.Info("Application Started");
            GlobalContext.Properties["page"] = new GetCurrentPage();
        }

        protected void Session_Start(object sender, EventArgs e)
        {
            Globals._Environment = WebAppConfig.getEnvironment(Request.Url.AbsoluteUri, Properties.Settings.Default.LocalOverride);
            log.Info(string.Format("Session Started ({0})", Globals._Environment));
        }

The latest specification allows line feed character, so a simple line break inside the attribute or entity 
 (note that characters # and ; are required) are OK.

Leading from answers from @Bozho and @aioobe, lexicographic comparisons are similar to the ordering that one might find in a dictionary.

The Java String class provides the .compareTo () method in order to lexicographically compare Strings. It is used like this "apple".compareTo ("banana").

The return of this method is an int which can be interpreted as follows:

• returns < 0 then the String calling the method is lexicographically first (comes first in a dictionary)
• returns == 0 then the two strings are lexicographically equivalent
• returns > 0 then the parameter passed to the compareTo method is lexicographically first.

More specifically, the method provides the first non-zero difference in ASCII values.

Thus "computer".compareTo ("comparison") will return a value of (int) 'u' - (int) 'a' (20). Since this is a positive result, the parameter ("comparison") is lexicographically first.

There is also a variant .compareToIgnoreCase () which will return 0 for "a".compareToIgnoreCase ("A"); for example.

I had the same problem on a methood that returns the status of the server. The application is deployed on multiple servers. So the easiest I found is to add

@CrossOrigin(origins = "*")
@RequestMapping(value="/schedulerActive")
public String isSchedulerActive(){
  //code goes here
}

This method is not secure but you can add allowCredentials for that.

do like

<input name="name" id="name" type="text" value="Name" 
   onblur="fillField(this,'Name');" onfocus="clearField(this,'Name');"/>

and js

function fillField(input,val) {
      if(input.value == "")
         input.value=val;
};

function clearField(input,val) {
      if(input.value == val)
         input.value="";
};

here is a demo fiddle of the same

It looks like we're going to be using ^(GIR ?0AA|[A-PR-UWYZ]([0-9]{1,2}|([A-HK-Y][0-9]([0-9ABEHMNPRV-Y])?)|[0-9][A-HJKPS-UW]) ?[0-9][ABD-HJLNP-UW-Z]{2})$, which is a slightly modified version of that sugested by Minglis above.

However, we're going to have to investigate exactly what the rules are, as the various solutions listed above appear to apply different rules as to which letters are allowed.

After some research, we've found some more information. Apparently a page on 'govtalk.gov.uk' points you to a postcode specification govtalk-postcodes. This points to an XML schema at XML Schema which provides a 'pseudo regex' statement of the postcode rules.

We've taken that and worked on it a little to give us the following expression:

^((GIR &0AA)|((([A-PR-UWYZ][A-HK-Y]?[0-9][0-9]?)|(([A-PR-UWYZ][0-9][A-HJKSTUW])|([A-PR-UWYZ][A-HK-Y][0-9][ABEHMNPRV-Y]))) &[0-9][ABD-HJLNP-UW-Z]{2}))$

This makes spaces optional, but does limit you to one space (replace the '&' with '{0,} for unlimited spaces). It assumes all text must be upper-case.

If you want to allow lower case, with any number of spaces, use:

^(([gG][iI][rR] {0,}0[aA]{2})|((([a-pr-uwyzA-PR-UWYZ][a-hk-yA-HK-Y]?[0-9][0-9]?)|(([a-pr-uwyzA-PR-UWYZ][0-9][a-hjkstuwA-HJKSTUW])|([a-pr-uwyzA-PR-UWYZ][a-hk-yA-HK-Y][0-9][abehmnprv-yABEHMNPRV-Y]))) {0,}[0-9][abd-hjlnp-uw-zABD-HJLNP-UW-Z]{2}))$

This doesn't cover overseas territories and only enforces the format, NOT the existence of different areas. It is based on the following rules:

Can accept the following formats:

• “GIR 0AA”
• A9 9ZZ
• A99 9ZZ
• AB9 9ZZ
• AB99 9ZZ
• A9C 9ZZ
• AD9E 9ZZ

Where:

• 9 can be any single digit number.
• A can be any letter except for Q, V or X.
• B can be any letter except for I, J or Z.
• C can be any letter except for I, L, M, N, O, P, Q, R, V, X, Y or Z.
• D can be any letter except for I, J or Z.
• E can be any of A, B, E, H, M, N, P, R, V, W, X or Y.
• Z can be any letter except for C, I, K, M, O or V.

tl;dr:

concat and append currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True to silence it. In the future the default will change to not sort, so it's best to specify either sort=True or False now, or better yet ensure that your non-concatenation indices match.

The warning is new in pandas 0.23.0:

In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned, link.

When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.

This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.

After some time the parameter sort was implemented in pandas.concat and DataFrame.append:

sort : boolean, default None

Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.

Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.

This has no effect when join='inner', which already preserves the order of the non-concatenation axis.

So if both DataFrames have the same columns in the same order, there is no warning and no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])

print (pd.concat([df1, df2]))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort is explicitly set (sort=None is the default value):

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=True))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=False))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a and b from df1 with a and b from df2 in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.

Lastly, if you pass sort=True, columns are sorted alphanumerically. If sort=False and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]}, 
                    columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]}, 
                    columns=['c','b','a','d'])

print (pd.concat([df1, df2]))

In your code:

placement_by_video_summary = placement_by_video_summary.drop(placement_by_video_summary_new.index)
                                                       .append(placement_by_video_summary_new, sort=True)
                                                       .sort_index()

In some cases it is tied to how the field is used. In some DB engines the field differences determine how (and if) you search for text in the field. CharFields are typically used for things that are searchable, like if you want to search for "one" in the string "one plus two". Since the strings are shorter they are less time consuming for the engine to search through. TextFields are typically not meant to be searched through (like maybe the body of a blog) but are meant to hold large chunks of text. Now most of this depends on the DB Engine and like in Postgres it does not matter.

Even if it does not matter, if you use ModelForms you get a different type of editing field in the form. The ModelForm will generate an HTML form the size of one line of text for a CharField and multiline for a TextField.

If you're going to be adding to this dictionary frequently you'd want to take a class based approach, something similar to @Latty's answer in this SO question 2d-dictionary-with-many-keys-that-will-return-the-same-value.

However, if you have a static dictionary, and you need only access values by multiple keys then you could just go the very simple route of using two dictionaries. One to store the alias key association and one to store your actual data:

alias = {
    'a': 'id1',
    'b': 'id1',
    'c': 'id2',
    'd': 'id2'
}

dictionary = {
    'id1': 1,
    'id2': 2
}

dictionary[alias['a']]

If you need to add to the dictionary you could write a function like this for using both dictionaries:

def add(key, id, value=None)
    if id in dictionary:
        if key in alias:
            # Do nothing
            pass
        else:
            alias[key] = id
    else:
        dictionary[id] = value
        alias[key] = id

add('e', 'id2')
add('f', 'id3', 3)

While this works, I think ultimately if you want to do something like this writing your own data structure is probably the way to go, though it could use a similar structure.

In seeking to fix the problem of pop-up, I discovered that Apple had a way around this concern.

Indeed, when you click on this link, if you installed the application, it is rerouted to it; otherwise, you will be redirected to the webpage, without any pop-up.

I 'tripped' across my solution after 2 days...XCODE 4.0

I've just upgraded to XCode 4.0 and this code signing issue has been a stunning frustrastion. And I've been doing this for over a year various versions...so if you are having problems, you are not alone.

I have recertified, reprovisioned, drag and dropped, manually edit the project file, deleted PROVISIIONING paths, stopped/started XCODE, stopped started keychain, checked spelling, checked bundle ID's, check my birth certificate, the phase of the moon, and taught my dog morse code...none of it worked!!!!

--bottom line---

1. Goto Targets... Build Settings tab
2. Go to the Code Signing identity block
   • Check Debug AND Distribution have the same code signing information ..in my case "IPhone Distribution:, dont let DEBUG be blank or not filled in.

If the Debug mode was not the same, it failed the Distribution mode as well...go figure. Hope that helps someone...

Figure: This shows how to find the relevant settings in XCode 4.5.

why does the Text take up the full space of the View, instead of just the space for "Hello"?

Because the View is a flex container and by default has flexDirection: 'column' and alignItems: 'stretch', which means that its children should be stretched out to fill its width.

(Note, per the docs, that all components in React Native are display: 'flex' by default and that display: 'inline' does not exist at all. In this way, the default behaviour of a Text within a View in React Native differs from the default behaviour of span within a div on the web; in the latter case, the span would not fill the width of the div because a span is an inline element by default. There is no such concept in React Native.)

How can the Text be floated / aligned to the right?

The float property doesn't exist in React Native, but there are loads of options available to you (with slightly different behaviours) that will let you right-align your text. Here are the ones I can think of:

1. Use textAlign: 'right' on the Text element

<View>
  <Text style={{textAlign: 'right'}}>Hello, World!</Text>
</View>

(This approach doesn't change the fact that the Text fills the entire width of the View; it just right-aligns the text within the Text.)

2. Use alignSelf: 'flex-end' on the Text

<View>
  <Text style={{alignSelf: 'flex-end'}}>Hello, World!</Text>
</View>

This shrinks the Text element to the size required to hold its content and puts it at the end of the cross direction (the horizontal direction, by default) of the View.

3. Use alignItems: 'flex-end' on the View

<View style={{alignItems: 'flex-end'}}>
  <Text>Hello, World!</Text>
</View>

This is equivalent to setting alignSelf: 'flex-end' on all the View's children.

4. Use flexDirection: 'row' and justifyContent: 'flex-end' on the View

<View style={{flexDirection: 'row', justifyContent: 'flex-end'}}>
  <Text>Hello, World!</Text>
</View>

flexDirection: 'row' sets the main direction of layout to be horizontal instead of vertical; justifyContent is just like alignItems, but controls alignment in the main direction instead of the cross direction.

5. Use flexDirection: 'row' on the View and marginLeft: 'auto' on the Text

<View style={{flexDirection: 'row'}}>
  <Text style={{marginLeft: 'auto'}}>Hello, World!</Text>
</View>

This approach is demonstrated, in the context of the web and real CSS, at https://stackoverflow.com/a/34063808/1709587.

6. Use position: 'absolute' and right: 0 on the Text:

<View>
  <Text style={{position: 'absolute', right: 0}}>Hello, World!</Text>
</View>

Like in real CSS, this takes the Text "out of flow", meaning that its siblings will be able to overlap it and its vertical position will be at the top of the View by default (although you can explicitly set a distance from the top of the View using the top style property).

Naturally, which of these various approaches you want to use - and whether the choice between them even matters at all - will depend upon your precise circumstances.

Was having an issue getting the "Run in Postman" links to work with the browsers until I added this to the .desktop file

MimeType=application/postman;x-scheme-handler/postman;

Also check your triggers.

Encountered this with a history table trigger which tried to insert the main table id into the history table id instead of the correct hist-table.source_id column.

The update statement did not touch the id column at all so took some time to find:

UPDATE source_table SET status = 0;

The trigger tried to do something similar to this:

FOR EACH ROW
BEGIN
    INSERT INTO `history_table` (`action`,`id`,`status`,`time_created`)
    VALUES('update', NEW.id, NEW.status, NEW.time_created);
END;

Was corrected to something like this:

FOR EACH ROW
BEGIN
    INSERT INTO `history_table` (`action`,`source_id`,`status`,`time_created`)
    VALUES('update', NEW.id, NEW.status, NEW.time_created);
END;

I might suggest the apache commons project. This project already provides a framework for doing what you need (i.e. flexible filtering of collections).

math.isnan()

or compare the number to itself. NaN is always != NaN, otherwise (e.g. if it is a number) the comparison should succeed.

Strange behaviour while debugging my app: require "active_support/notifications" (rdb:1) p ENV['RAILS_ENV'] "test" (rdb:1) p Rails.env "development"

I would say that you should stick to one or another (and preferably Rails.env)

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

According to the documentation, it is better to handle multiple exceptions through tuples or like this:

import sys

try:
    f = open('myfile.txt')
    s = f.readline()
    i = int(s.strip())
except IOError as e:
    print "I/O error({0}): {1}".format(e.errno, e.strerror)
except ValueError:
    print "Could not convert data to an integer."
except:
    print "Unexpected error: ", sys.exc_info()[0]
    raise

Tried a combination of some answers and this eventually worked:

sudo -H pip install --upgrade --ignore-installed awsebcli

Cheers

Make sure ~/.ssh/known_hosts is writable. That fixed it for me.

I had this same exact problem, except that i have never used IIS. While I was fixing another system bug, I had set the apache service to manual start, hoping to reduce the complexity of my system. After I fixed the other bug, apache wouldn't start. I futzed for a while, but all it took was setting apache back to automatic start: Start > Administrative Tools > Services.

Apparently when Apache starts this way, it claims port 80 before the SYSTEM process can.

hth someone. all my googling turned up the 'can't have IIS and Apache on the same machine.' this is for the other one percent of us.

The answer about threading is good, but you need to be a bit more specific about what you want to do.

If you have two functions that both use a lot of CPU, threading (in CPython) will probably get you nowhere. Then you might want to have a look at the multiprocessing module or possibly you might want to use jython/IronPython.

If CPU-bound performance is the reason, you could even implement things in (non-threaded) C and get a much bigger speedup than doing two parallel things in python.

Without more information, it isn't easy to come up with a good answer.

@media queries serve this purpose. Here's an example:

@media only screen and (max-width: 991px) and (min-width: 769px){
 /* CSS that should be displayed if width is equal to or less than 991px and larger 
  than 768px goes here */
}

@media only screen and (max-width: 991px){
 /* CSS that should be displayed if width is equal to or less than 991px goes here */
}

It specifies an "Anchor", or a position on the page, and allows you to "jump" or "scroll" to that position on the page.

Please see this page for more details.

Using JDK 1.6 or later

It has been pointed out by Justin in the comments below that keytool alone is capable of doing this using the following command (although only in JDK 1.6 and later):

keytool -importkeystore -srckeystore mypfxfile.pfx -srcstoretype pkcs12 
-destkeystore clientcert.jks -deststoretype JKS

Using JDK 1.5 or below

OpenSSL can do it all. This answer on JGuru is the best method that I've found so far.

Firstly make sure that you have OpenSSL installed. Many operating systems already have it installed as I found with Mac OS X.

The following two commands convert the pfx file to a format that can be opened as a Java PKCS12 key store:

openssl pkcs12 -in mypfxfile.pfx -out mypemfile.pem
openssl pkcs12 -export -in mypemfile.pem -out mykeystore.p12 -name "MyCert"

NOTE that the name provided in the second command is the alias of your key in the new key store.

You can verify the contents of the key store using the Java keytool utility with the following command:

keytool -v -list -keystore mykeystore.p12 -storetype pkcs12

Finally if you need to you can convert this to a JKS key store by importing the key store created above into a new key store:

keytool -importkeystore -srckeystore mykeystore.p12 -destkeystore clientcert.jks -srcstoretype pkcs12 -deststoretype JKS

You can use set with the /p argument:

SET /P variable=[promptString]

The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

So, simply use something like

set /p Input=Enter some text: 

Later you can use that variable as argument to a command:

myCommand %Input%

Be careful though, that if your input might contain spaces it's probably a good idea to quote it:

myCommand "%Input%"

There are two ways:

1. Use the axes methods of the subplot object (e.g. ax.set_xticks and ax.set_xticklabels) or
2. Use plt.sca to set the current axes for the pyplot state machine (i.e. the plt interface).

As an example (this also illustrates using setp to change the properties of all of the subplots):

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=3, ncols=4)

# Set the ticks and ticklabels for all axes
plt.setp(axes, xticks=[0.1, 0.5, 0.9], xticklabels=['a', 'b', 'c'],
        yticks=[1, 2, 3])

# Use the pyplot interface to change just one subplot...
plt.sca(axes[1, 1])
plt.xticks(range(3), ['A', 'Big', 'Cat'], color='red')

fig.tight_layout()
plt.show()

don't they both keep a value for another request?

Yes they do, but when the first one is void, the second one returns and object:

public void Keep(string key)
{
    _retainedKeys.Add(key); // just adds the key to the collection for retention
}

public object Peek(string key)
{
    object value;
    _data.TryGetValue(key, out value);
    return value; // returns an object without marking it for deletion
}

I think it is most useful as a compile-time reminder that the intention of the method is to override a parent method. As an example:

protected boolean displaySensitiveInformation() {
  return false;
}

You will often see something like the above method that overrides a method in the base class. This is an important implementation detail of this class -- we don't want sensitive information to be displayed.

Suppose this method is changed in the parent class to

protected boolean displaySensitiveInformation(Context context) {
  return true;
}

This change will not cause any compile time errors or warnings - but it completely changes the intended behavior of the subclass.

To answer your question: you should use the @Override annotation if the lack of a method with the same signature in a superclass is indicative of a bug.

ORIGINAL ANSWER
Give this a shot:

1. In Visual Studio, open your app.config or web.config file.
2. Go to the "XML" menu and select "Create Schema". This action should create a new file called "app.xsd" or "web.xsd".
3. Save that file to your disk.
4. Go back to your app.config or web.config and in the edit window, right click and select properties. From there, make sure the xsd you just generated is referenced in the Schemas property. If it's not there then add it.

That should cause those messages to disappear.

I saved my web.xsd in the root of my web folder (which might not be the best place for it, but just for demonstration purposes) and my Schemas property looks like this:

"C:\Program Files (x86)\Microsoft Visual Studio 10.0\xml\Schemas\DotNetConfig.xsd" "Web.xsd"

Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation semantics (the look and formatting) of a document written in a markup language. more info : http://en.wikipedia.org/wiki/Cascading_Style_Sheets CSS is not a programming language, and does not have the tools that come with a server side language like PHP. However, we can use Server-side languages to generate style sheets.

There is no notion of method overloading in Python. But you can achieve a similar effect by specifying optional and keyword arguments

I think it's all personal preference. My preferences come from using NHibernate, in .NET, with SQL Server, so they probably differ from what others use.

• Databases: The application that's being used.. ex: Stackoverflow
• Collections: Singular in name, what it's going to be a collection of, ex: Question
• Document fields, ex: MemberFirstName

Honestly, it doesn't matter too much, as long as it's consistent for the project. Just get to work and don't sweat the details :P

If you don't mind reading bytecode, javap should work fine. It's part of the standard JDK installation.

Usage: javap <options> <classes>...

where options include:
   -c                        Disassemble the code
   -classpath <pathlist>     Specify where to find user class files
   -extdirs <dirs>           Override location of installed extensions
   -help                     Print this usage message
   -J<flag>                  Pass <flag> directly to the runtime system
   -l                        Print line number and local variable tables
   -public                   Show only public classes and members
   -protected                Show protected/public classes and members
   -package                  Show package/protected/public classes
                             and members (default)
   -private                  Show all classes and members
   -s                        Print internal type signatures
   -bootclasspath <pathlist> Override location of class files loaded
                             by the bootstrap class loader
   -verbose                  Print stack size, number of locals and args for methods
                             If verifying, print reasons for failure

a more modern approach would be to use css flex-box.

div {_x000D_
  height: 50px;_x000D_
  background: grey;_x000D_
  display: flex;_x000D_
  align-items: center_x000D_
}

<div>_x000D_
  <label for='name'>Name:</label>_x000D_
  <input type='text' id='name' />_x000D_
</div>

a more complex example... if you have multible elements in the flex flow, you can use align-self to align single elements differently to the specified align...

div {_x000D_
  display: flex;_x000D_
  align-items: center_x000D_
}_x000D_
_x000D_
* {_x000D_
  margin: 10px_x000D_
}_x000D_
_x000D_
label {_x000D_
  align-self: flex-start_x000D_
}

<div>_x000D_
  <img src="https://de.gravatar.com/userimage/95932142/195b7f5651ad2d4662c3c0e0dccd003b.png?size=50" />_x000D_
  <label>Text</label>_x000D_
  <input placeholder="Text" type="text" />_x000D_
</div>

its also super easy to center horizontally and vertically:

div {_x000D_
  position:absolute;_x000D_
  top:0;left:0;right:0;bottom:0;_x000D_
  background: grey;_x000D_
  display: flex;_x000D_
  align-items: center;_x000D_
  justify-content:center_x000D_
}

<div>_x000D_
  <label for='name'>Name:</label>_x000D_
  <input type='text' id='name' />_x000D_
</div>

When doing django ranges with a filter make sure you know the difference between using a date object vs a datetime object. __range is inclusive on dates but if you use a datetime object for the end date it will not include the entries for that day if the time is not set.

    startdate = date.today()
    enddate = startdate + timedelta(days=6)
    Sample.objects.filter(date__range=[startdate, enddate])

returns all entries from startdate to enddate including entries on those dates. Bad example since this is returning entries a week into the future, but you get the drift.

    startdate = datetime.today()
    enddate = startdate + timedelta(days=6)
    Sample.objects.filter(date__range=[startdate, enddate])

will be missing 24 hours worth of entries depending on what the time for the date fields is set to.

Try adding All the following, In my application it is working fine with tomcat

 @EnableJpaRepositories("my.package.base.*")
 @ComponentScan(basePackages = { "my.package.base.*" })
 @EntityScan("my.package.base.*")   

I am using spring boot, and when i am using embedded tomcat it was working fine with out @EntityScan("my.package.base.*") but when I tried to deploy the app to an external tomcat I got not a managed type error for my entity.

$(".draggable")
.mousedown(function(e){
    $(this).on("mousemove",function(e){
        var p1 = { x: e.pageX, y: e.pageY };
        var p0 = $(this).data("p0") || p1;
        console.log("dragging from x:" + p0.x + " y:" + p0.y + "to x:" + p1.x + " y:" + p1.y);
        $(this).data("p0", p1);
    });
})
.mouseup(function(){
    $(this).off("mousemove");
});

This solution uses the "on" and "off" functions to bind an unbind a mousemove event (bind and unbind are deprecated). You can also detect the change in mouse x and y positions between two mousemove events.

rand() return a int between 0 and RAND_MAX. To get a random number between 0.0 and 1.0, first cast the int return by rand() to a float, then divide by RAND_MAX.

I just did the same. I did it in helper controller, my code is:

def get_controller_name
  controller_name    
end


def get_action_name
  action_name   
end

These methods will return current contoller and action name. Hope it helps

You may use GifAnimationDrawable library found in this link - https://github.com/Hipmob/gifanimateddrawable, and which convert any gif to AnimationDrawable. Enjoy :)

in regard of answer from @Perception, its true to be very memory-consuming when working with byte arrays, but you could also simply write back into the outputstream

@Path("/picture")
public class ProfilePicture {
  @GET
  @Path("/thumbnail")
  @Produces("image/png")
  public StreamingOutput getThumbNail() {
    return new StreamingOutput() {
      @Override
      public void write(OutputStream os) throws IOException, WebApplicationException {
        //... read your stream and write into os
      }
    };
  }
}

call your (windows-)git with cygpath as parameter, in order to convert the "calling path". I m confused why that should be a problem.

You can use matplotlib to plot the histogram and the PDF (as in the link in @MrE's answer). For fitting and for computing the PDF, you can use scipy.stats.norm, as follows.

import numpy as np
from scipy.stats import norm
import matplotlib.pyplot as plt


# Generate some data for this demonstration.
data = norm.rvs(10.0, 2.5, size=500)

# Fit a normal distribution to the data:
mu, std = norm.fit(data)

# Plot the histogram.
plt.hist(data, bins=25, density=True, alpha=0.6, color='g')

# Plot the PDF.
xmin, xmax = plt.xlim()
x = np.linspace(xmin, xmax, 100)
p = norm.pdf(x, mu, std)
plt.plot(x, p, 'k', linewidth=2)
title = "Fit results: mu = %.2f,  std = %.2f" % (mu, std)
plt.title(title)

plt.show()

Here's the plot generated by the script:

Remember Running Background, Running continuously are two different tasks.

For long-term background processes, Threads aren't optimal with Android. However, here's the code and do it at your own risk...

Remember Service or Thread will run in the background but our task needs to make trigger (call again and again) to get updates, i.e. once the task is completed we need to recall the function for next update.

Timer (periodic trigger), Alarm (Timebase trigger), Broadcast (Event base Trigger), recursion will awake our functions.

public static boolean isRecursionEnable = true;

void runInBackground() {
    if (!isRecursionEnable)
        // Handle not to start multiple parallel threads
        return;

    // isRecursionEnable = false; when u want to stop
    // on exception on thread make it true again  
    new Thread(new Runnable() {
        @Override
        public void run() {
            // DO your work here
            // get the data
            if (activity_is_not_in_background) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        // update UI
                        runInBackground();
                    }
                });
            } else {
                runInBackground();
            }
        }
    }).start();
}

Using Service: If you launch a Service it will start, It will execute the task, and it will terminate itself. after the task execution. terminated might also be caused by exception, or user killed it manually from settings. START_STICKY (Sticky Service) is the option given by android that service will restart itself if service terminated.

Remember the question difference between multiprocessing and multithreading? Service is a background process (Just like activity without UI), The same way how you launch thread in the activity to avoid load on the main thread (Activity thread), the same way you need to launch threads(or async tasks) on service to avoid load on service.

In a single statement, if you want a run a background continues task, you need to launch a StickyService and run the thread in the service on event base

reset has been replaced by flush with Django 1.5, see:

python manage.py help flush

I usually use the second one of these:

from matplotlib.pyplot import cm
import numpy as np

#variable n below should be number of curves to plot

#version 1:

color=cm.rainbow(np.linspace(0,1,n))
for i,c in zip(range(n),color):
   plt.plot(x, y,c=c)

#or version 2:

color=iter(cm.rainbow(np.linspace(0,1,n)))
for i in range(n):
   c=next(color)
   plt.plot(x, y,c=c)

Example of 2:

If you look at the JarFile API you'll see that it's a subclass of the ZipFile class.

The jar-specific classes mostly just add jar-specific functionality, like direct support for manifest file attributes and so on.

It's OOP "in action"; since jar files are zip files, the jar classes can use zip functionality and provide additional utility.

Is there an issue using the Date.toString().indexOf('Daylight Time') > -1

"" + new Date()

Sat Jan 01 100050 00:00:00 GMT-0500 (Eastern Standard Time)

"" + new Date(...)

This seems compatible with all browsers.

> selects immediate children

For example, if you have nested divs like such:

<div class='outer'>
    <div class="middle">
        <div class="inner">...</div>
    </div>
    <div class="middle">
        <div class="inner">...</div>
    </div>
</div>

and you declare a css rule in your stylesheet like such:

.outer > div {
    ...
}

your rules will apply only to those divs that have a class of "middle" since those divs are direct descendants (immediate children) of elements with class "outer" (unless, of course, you declare other, more specific rules overriding these rules). See fiddle.

div {_x000D_
  border: 1px solid black;_x000D_
  padding: 10px;_x000D_
}_x000D_
.outer > div {_x000D_
  border: 1px solid orange;_x000D_
}

<div class='outer'>_x000D_
  div.outer - This is the parent._x000D_
  <div class="middle">_x000D_
    div.middle - This is an immediate child of "outer". This will receive the orange border._x000D_
    <div class="inner">div.inner - This is an immediate child of "middle". This will not receive the orange border.</div>_x000D_
  </div>_x000D_
  <div class="middle">_x000D_
    div.middle - This is an immediate child of "outer". This will receive the orange border._x000D_
    <div class="inner">div.inner - This is an immediate child of "middle". This will not receive the orange border.</div>_x000D_
  </div>_x000D_
</div>_x000D_
_x000D_
<p>Without Words</p>_x000D_
_x000D_
<div class='outer'>_x000D_
  <div class="middle">_x000D_
    <div class="inner">...</div>_x000D_
  </div>_x000D_
  <div class="middle">_x000D_
    <div class="inner">...</div>_x000D_
  </div>_x000D_
</div>

Side note

If you, instead, had a space between selectors instead of >, your rules would apply to both of the nested divs. The space is much more commonly used and defines a "descendant selector", which means it looks for any matching element down the tree rather than just immediate children as the > does.

NOTE: The > selector is not supported by IE6. It does work in all other current browsers though, including IE7 and IE8.

If you're looking into less-well-used CSS selectors, you may also want to look at +, ~, and [attr] selectors, all of which can be very useful.

This page has a full list of all available selectors, along with details of their support in various browsers (its mainly IE that has problems), and good examples of their usage.

It worked for me. You can try with this also to show the keyboard:
