Try using tqdm.notebook.tqdm instead of tqdm, as outlined here.

This could be as simple as changing your import to:

from tqdm.notebook import tqdm

Good luck!

EDIT: After testing, it seems that tqdm actually works fine in 'text mode' in Jupyter notebook. It's hard to tell because you haven't provided a minimal example, but it looks like your problem is caused by a print statement in each iteration. The print statement is outputting a number (~0.89) in between each status bar update, which is messing up the output. Try removing the print statement.

You can also use the hmisc package that will give you the following percentiles:

0.05, 0.1, 0.25, 0.5, 0.75, 0.9 , 0.95

Just use the describe(table_ages)

I thought I would contribute by providing a concrete example of the practical use of the scale function. Say you have 3 test scores (Math, Science, and English) that you want to compare. Maybe you may even want to generate a composite score based on each of the 3 tests for each observation. Your data could look as as thus:

student_id <- seq(1,10)
math <- c(502,600,412,358,495,512,410,625,573,522)
science <- c(95,99,80,82,75,85,80,95,89,86)
english <- c(25,22,18,15,20,28,15,30,27,18)
df <- data.frame(student_id,math,science,english)

Obviously it would not make sense to compare the means of these 3 scores as the scale of the scores are vastly different. By scaling them however, you have more comparable scoring units:

z <- scale(df[,2:4],center=TRUE,scale=TRUE)

You could then use these scaled results to create a composite score. For instance, average the values and assign a grade based on the percentiles of this average. Hope this helped!

Note: I borrowed this example from the book "R In Action". It's a great book! Would definitely recommend.

It is better to not subset the variables inside aes(), and instead transform your data:

df1 <- unstack(df,form = price~product)
df1$skew <- rep(letters[2:1],each = 4)

p1 <- ggplot(df1, aes(x=p1, y=p3, colour=factor(skew))) + 
        geom_point(size=2, shape=19)
p1

Maybe you want to use CSS "clip-path" (Works with transparency and background)

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

Just set your default CSS on your images like so:

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

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

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

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

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

Centering

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

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

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

Conclusion

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

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

One of the reason may be improper date/time of your PC.

In Ubuntu PC to check the date and time using:

date

Example, One of the ways to update date and time is:

date -s "23 MAR 2017 17:06:00"

This problem was due to the use of AngularJS 1.1.5 (which was unstable, and obviously had some bug or different implementation of the routing than it was in 1.0.7)

turning it back to 1.0.7 solved the problem instantly.

have tried the 1.2.0rc1 version, but have not finished testing as I had to rewrite some of the router functionality since they took it out of the core.

anyway, this problem is fixed when using AngularJS vs 1.0.7.

I got the color range to be asymmetric simply by changing the symkey argument to FALSE

symm=F,symkey=F,symbreaks=T, scale="none"

Solved the color issue with colorRampPalette with the breaks argument to specify the range of each color, e.g.

colors = c(seq(-3,-2,length=100),seq(-2,0.5,length=100),seq(0.5,6,length=100))

my_palette <- colorRampPalette(c("red", "black", "green"))(n = 299)

Altogether

heatmap.2(as.matrix(SeqCountTable), col=my_palette, 
    breaks=colors, density.info="none", trace="none", 
        dendrogram=c("row"), symm=F,symkey=F,symbreaks=T, scale="none")

Try this example and see if it fits your needs, there are three main aspects to it.

1. Line.Stretch is set to fill.

2. For horizontal lines the VerticalAlignment of the line is set Bottom, and for VerticalLines the HorizontalAlignment is set to Right.

3. We then need to tell the line how many rows or columns to span, this is done by binding to either RowDefinitions or ColumnDefintions count property.

Is there a good interactive 3D graph library out there?

The accepted answer suggests the following program, which apparently has python bindings: http://ubietylab.net/ubigraph/

Edit

I'm not sure about the interactivity of NetworkX, but you can definitely make 3D graphs. There is at least one example in the gallery:

http://networkx.lanl.gov/examples/drawing/edge_colormap.html

And another example in the 'examples'. This one, however, requires that you have Mayavi.

http://networkx.lanl.gov/examples/3d_drawing/mayavi2_spring.html

$(".oSlider-rotate").slider({
     min: 10,
     max: 74,
     step: .01,
     value: 24,
     slide: function(e,ui){
                 $('.user-text').css('transform', 'scale(' + ui.value + ')')

            }                
  });

This will solve the issue

Unless there is some other requirement not specified, I would simply convert your color image to grayscale and work with that only (no need to work on the 3 channels, the contrast present is too high already). Also, unless there is some specific problem regarding resizing, I would work with a downscaled version of your images, since they are relatively large and the size adds nothing to the problem being solved. Then, finally, your problem is solved with a median filter, some basic morphological tools, and statistics (mostly for the Otsu thresholding, which is already done for you).

Here is what I obtain with your sample image and some other image with a sheet of paper I found around:

The median filter is used to remove minor details from the, now grayscale, image. It will possibly remove thin lines inside the whitish paper, which is good because then you will end with tiny connected components which are easy to discard. After the median, apply a morphological gradient (simply dilation - erosion) and binarize the result by Otsu. The morphological gradient is a good method to keep strong edges, it should be used more. Then, since this gradient will increase the contour width, apply a morphological thinning. Now you can discard small components.

At this point, here is what we have with the right image above (before drawing the blue polygon), the left one is not shown because the only remaining component is the one describing the paper:

Given the examples, now the only issue left is distinguishing between components that look like rectangles and others that do not. This is a matter of determining a ratio between the area of the convex hull containing the shape and the area of its bounding box; the ratio 0.7 works fine for these examples. It might be the case that you also need to discard components that are inside the paper, but not in these examples by using this method (nevertheless, doing this step should be very easy especially because it can be done through OpenCV directly).

For reference, here is a sample code in Mathematica:

f = Import["http://thwartedglamour.files.wordpress.com/2010/06/my-coffee-table-1-sa.jpg"]
f = ImageResize[f, ImageDimensions[f][[1]]/4]
g = MedianFilter[ColorConvert[f, "Grayscale"], 2]
h = DeleteSmallComponents[Thinning[
     Binarize[ImageSubtract[Dilation[g, 1], Erosion[g, 1]]]]]
convexvert = ComponentMeasurements[SelectComponents[
     h, {"ConvexArea", "BoundingBoxArea"}, #1 / #2 > 0.7 &], 
     "ConvexVertices"][[All, 2]]
(* To visualize the blue polygons above: *)
Show[f, Graphics[{EdgeForm[{Blue, Thick}], RGBColor[0, 0, 1, 0.5], 
     Polygon @@ convexvert}]]

If there are more varied situations where the paper's rectangle is not so well defined, or the approach confuses it with other shapes -- these situations could happen due to various reasons, but a common cause is bad image acquisition -- then try combining the pre-processing steps with the work described in the paper "Rectangle Detection based on a Windowed Hough Transform".

In C++, your source files are usually parsed from top to bottom in a single pass, so any variable or function must be declared before they can be used. There are some exceptions to this, like when defining functions inline in a class definition, but that's not the case for your code.

Either move the definition of integrate above the one for getSkewNormal, or add a forward declaration above getSkewNormal:

double integrate (double start, double stop, int numSteps, Evaluatable evalObj);

The same applies for sum.

The height in percent of the containing element (like "20%").

So I think they mean the element where the div is in?

Try to make the bounds's size integer.

#include <math.h>
....

    if (ratio > 1) {
        bounds.size.width = resolution;
        bounds.size.height = round(bounds.size.width / ratio);
    } else {
        bounds.size.height = resolution;
        bounds.size.width = round(bounds.size.height * ratio);
    }

HTML:

<style>
#foo, #bar{
    width: 50px; /* use any width or height */
    height: 50px;
    background-position: center center;
    background-repeat: no-repeat;
    background-size: cover;
}
</style>

<div id="foo" style="background-image: url('path/to/image1.png');">
<div id="bar" style="background-image: url('path/to/image2.png');">

JSFiddle

...And if you want to set or change the image (using #foo as an example):

jQuery:

$("#foo").css("background-image", "url('path/to/image.png')");

JavaScript:

document.getElementById("foo").style.backgroundImage = "url('path/to/image.png')";

Dirk has explained how to plot the density function over the histogram. But sometimes you might want to go with the stronger assumption of a skewed normal distribution and plot that instead of density. You can estimate the parameters of the distribution and plot it using the sn package:

> sn.mle(y=c(rep(65, times=5), rep(25, times=5), rep(35, times=10), rep(45, times=4)))
$call
sn.mle(y = c(rep(65, times = 5), rep(25, times = 5), rep(35, 
    times = 10), rep(45, times = 4)))

$cp
    mean     s.d. skewness 
41.46228 12.47892  0.99527 

This probably works better on data that is more skew-normal:

Before take the width make the parent display show ,then take the width and finally make the parent display hide. Just like following

$('#parent').show();
var tableWidth = $('#parent').children('table').outerWidth();
 $('#parent').hide();
if (tableWidth > $('#parent').width())
{
    $('#parent').width() = tableWidth;
}

Using Javascript:

document.querySelector('#edit-submitted-first-name').required = false;

Using jQuery:

$('#edit-submitted-first-name').removeAttr('required');

With Node and HTML alone you won't be able to achieve what you intend to; it's not like using PHP, where you could do something like <title> <?php echo $custom_title; ?>, without any other stuff installed.

To do what you want using Node, you can either use something that's called a 'templating' engine (like Jade, check this out) or use some HTTP requests in Javascript to get your data from the server and use it to replace parts of the HTML with it.

Both require some extra work; it's not as plug'n'play as PHP when it comes to doing stuff like you want.

For Current date and time as the name for a file on the file system. Now call the string.Format method, and combine it with DateTime.Now, for a method that outputs the correct string based on the date and time.

using System;
using System.IO;

class Program
{
    static void Main()
    {
        //
        // Write file containing the date with BIN extension
        //
        string n = string.Format("text-{0:yyyy-MM-dd_hh-mm-ss-tt}.bin",
            DateTime.Now);
        File.WriteAllText(n, "abc");
    }
}

Output :

C:\Users\Fez\Documents\text-2020-01-08_05-23-13-PM.bin

"text-{0:yyyy-MM-dd_hh-mm-ss-tt}.bin"

text- The first part of the output required Files will all start with text-

{0: Indicates that this is a string placeholder The zero indicates the index of the parameters inserted here

yyyy- Prints the year in four digits followed by a dash This has a "year 10000" problem

MM- Prints the month in two digits

dd_ Prints the day in two digits followed by an underscore

hh- Prints the hour in two digits

mm- Prints the minute, also in two digits

ss- As expected, it prints the seconds

tt Prints AM or PM depending on the time of day

Apple lifted the restrictions on non-Objective C/C/C++ apps -- you just can't load code that isn't in the app bundle.

MonoTouch lets you use .NET languages -- C# is directly supported, but if you have Windows, you can make assemblies in any .NET language and use it.

There are rumors that Apple is going to support other languages directly -- I keep hearing ruby, but they are just rumors.

I think Lua is being used for game logic on a lot of apps.

EDIT (in 2018): Generally you can use any language that you can get to compile for iOS or even install language interpreters. The main thing you cannot do is load code from the Internet that wasn't in the app bundle.

People do this all of the time anyway (see React Native apps loading JavaScript from servers), but, technically, it's not allowed. The main thing that will get you attention from Apple if you make some kind of App Store that loads whole App-like things.

EDIT (in 2020): from @Pylot in comments: I know this is a long time ago, but now at least technically you can load code that isn’t embedded in the app, as you can write with JavaScript using the webview. Not staying your answer is wrong or anything, I definitely agree with you. but I was looking for something and found this post on the way. Figured if anyone sees this it might help them out.

I would suggest hinterland extension.

In other answers I couldn't find the method for how to install it from pip, so this is how you install it.

First, install jupyter contrib nbextensions by running

pip install jupyter_contrib_nbextensions

Next install js and css file for jupyter by running

jupyter contrib nbextension install --user

and at the end run,

jupyter nbextension enable hinterland/hinterland

The output of last command will be

If you have trouble with caching ajax you can turn it off:

$.ajaxSetup({cache: false});

var byteCharacters = atob(response.data);
var byteNumbers = new Array(byteCharacters.length);
for (var i = 0; i < byteCharacters.length; i++) {
  byteNumbers[i] = byteCharacters.charCodeAt(i);
}
var byteArray = new Uint8Array(byteNumbers);
var file = new Blob([byteArray], { type: 'application/pdf;base64' });
var fileURL = URL.createObjectURL(file);
window.open(fileURL);

You return a base64 string from the API or another source. You can also download it.

I reached the point that I set, up to max_iter=1200000 on my LinearSVC classifier, but still the "ConvergenceWarning" was still present. I fix the issue by just setting dual=False and leaving max_iter to its default.

With LogisticRegression(solver='lbfgs') classifier, you should increase max_iter. Mine have reached max_iter=7600 before the "ConvergenceWarning" disappears when training with large dataset's features.

core.autocrlf=input is the right setting for what you want, but you might have to do a git update-index --refresh and/or a git reset --hard for the change to take effect.

With core.autocrlf set to input, git will not apply newline-conversion on check-out (so if you have LF in the repo, you'll get LF), but it will make sure that in case you mess up and introduce some CRLFs in the working copy somehow, they won't make their way into the repo.

        if word not in std_embeddings_index :
            word_vector = np.array(np.random.uniform(-1.0, 1.0, 300))
            std_embeddings_index[word] = word_vector
        else:
            word_vector = std_embeddings_index[word]
        sent_vector = sent_vector + word_vector

    return sent_vector

def cosine_sim(sent1, sent2):
    return cosineValue(get_sentence_vector(sent1), get_sentence_vector(sent2))

I did run for the given sentences and found the following results

s1 = "This is a foo bar sentence ."
s2 = "This sentence is similar to a foo bar sentence ."
s3 = "What is this string ? Totally not related to the other two lines ."

print cosine_sim(s1, s2) # Should give high cosine similarity
print cosine_sim(s1, s3) # Shouldn't give high cosine similarity value
print cosine_sim(s2, s3) # Shouldn't give high cosine similarity value

Instead of getViewById(), use

MenuItem item = getToolbar().getMenu().findItem(Menu.FIRST);

replacing the Menu.FIRST with your menu item id.

@Marton had an important objection to the accepted answer on the grounds that the pipe creates a new collection on each change detection. I would instead create an HtmlService which provides a range of utility functions which the view can use as follows:

@Component({
  selector: 'app-myview',
  template: `<div *ngFor="let i of html.keys(items)">{{i + ' : ' + items[i]}}</div>`
})
export class MyComponent {
  items = {keyOne: 'value 1', keyTwo: 'value 2', keyThree: 'value 3'};
  constructor(private html: HtmlService){}
}

@Injectable()
export class HtmlService {
  keys(object: {}) {
    return Object.keys(object);
  }
  // ... other useful methods not available inside html, like isObject(), isArray(), findInArray(), and others...
}

After a lot of trial and error I found this solved my problems. This is used to display photos on TVs via a browser.

• It Keeps the photos aspect ratio
• Scales in vertical and horizontal
• Centers vertically and horizontal

• The only thing to watch for are really wide images. They do stretch to fill, but not by much, standard camera photos are not altered.

  Give it a try :)

In your controller, render the new action from your create action if validation fails, with an instance variable, @car populated from the user input (i.e., the params hash). Then, in your view, add a logic check (either an if block around the form or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car is set.

Add the following in your index.php file. I first came across this when I moved my application from my XAMPP server to Apache 2.2 and PHP 5.4...

I would advise you do it in your index.php file instead of the php.ini file.

if( ! ini_get('date.timezone') )
{
    date_default_timezone_set('GMT');
}

Just wanted to add that while:

git checkout -b {branchName}

Creates a new branch, it also checks out that branch / makes it your current branch. If, for some reason, all you want to do is snap off a branch but not make it your current branch, then you would use the following command:

git branch {branchName}

In the first command, "checkout" makes said branch your current branch, and the "-b" means: this branch doesn't exist yet, so make it for me.

A dirty trick I somtimes use, is hiding variables in the 'name' attribute (that I normally don't use for other purposes):

select onFocus=(this.name=this.value) onChange=someFunction(this.name,this.value)><option...

Somewhat unexpectedly, both the old and the new value is then submitted to someFunction(oldValue,newValue)

Run the following command at your node.js command prompt where "<git path>" is the path to your git bin folder:

set PATH=%PATH%;<git path>;

So, like this:

set PATH=%PATH%;C:\Program Files\Git\bin;

Or this: (Notice the (x86) )

set PATH=%PATH%;C:\Program Files (x86)\Git\bin;

This will add git to your path variables. Be sure you type it correctly or you could possibly delete your path vars which would be bad.

Difficulties with defining, what's legal and not were already adressed and whitelists were suggested. But Windows supports more-than-8-bit characters. Wikipedia states, that (for example) the

modifier letter colon [(See 7. below) is] sometimes used in Windows filenames as it is identical to the colon in the Segoe UI font used for filenames. The [inherited ASCII] colon itself is not permitted.

Therefore, I want to present a much more liberal approach using Unicode characters to replace the "illegal" ones. I found the result in my comparable use-case by far more readable. Plus you can even restore the original content from the replacements. Possible choices and research are provided in the following list:

1. Instead of * (U+002A * ASTERISK), you can use one of the many listed, for example U+2217 * (ASTERISK OPERATOR) or the Full Width Asterisk U+FF0A *
2. Instead of ., you can use one of these, for example · U+22C5 dot operator
3. Instead of ", you can use “ U+201C english leftdoublequotemark (Alternatives see here)
4. Instead of / (/ SOLIDUS U+002F ), you can use / DIVISION SLASH U+2215 (others here)
5. Instead of \ (\ U+005C Reverse solidus), you can use ? U+29F5 Reverse solidus operator (more)
6. Instead of [ (U+005B Left square bracket) and ] (U+005D Right square bracket), you can use for example U+FF3B[ FULLWIDTH LEFT SQUARE BRACKET and U+FF3D ]FULLWIDTH RIGHT SQUARE BRACKET (from here, more possibilities here)
7. Instead of :, you can use U+2236 : RATIO (for mathematical usage) or U+A789 ? MODIFIER LETTER COLON, (see colon (letter), sometimes used in Windows filenames as it is identical to the colon in the Segoe UI font used for filenames. The colon itself is not permitted) (See here)
8. Instead of ;, you can use U+037E ; GREEK QUESTION MARK (see here)
9. For |, there are some good substitutes such as: U+0964 ? DEVANAGARI DANDA, U+2223 | DIVIDES or U+01C0 | LATIN LETTER DENTAL CLICK (Wikipedia). Also the box drawing characters contain various other options.
10. Instead of , (, U+002C COMMA), you can use for example ‚ U+201A SINGLE LOW-9 QUOTATION MARK (see here)
11. For ? (U+003F ? QUESTION MARK), these are good candidates: U+FF1F ? FULLWIDTH QUESTION MARK or U+FE56 ? SMALL QUESTION MARK (from here, two more from Dingbats Block, search for "question")

For additional ideas, you can also look for example into this block. In Windows, these special characters should theoretically be able to be typed by using an alt-code, but I only found a solution to insert it in Microsoft Office in this Microsoft article using ALT + X. It can of course still be copied instead of typed.

You're running your Python 3 code with a Python 2 interpreter. If you weren't, your print statement would throw up a SyntaxError before it ever prompted you for input.

The result is that you're using Python 2's input, which tries to eval your input (presumably sdas), finds that it's invalid Python, and dies.

xargs fails with with backslashes, quotes. It needs to be something like

ls -1 |tr \\n \\0 |xargs -0 -iTHIS echo "THIS is a file."

xargs -0 option:

-0, --null
          Input  items are terminated by a null character instead of by whitespace, and the quotes and backslash are
          not special (every character is taken literally).  Disables the end of file string, which is treated  like
          any  other argument.  Useful when input items might contain white space, quote marks, or backslashes.  The
          GNU find -print0 option produces input suitable for this mode.

ls -1 terminates the items with newline characters, so tr translates them into null characters.

This approach is about 50 times slower than iterating manually with for ... (see Michael Aaron Safyans answer) (3.55s vs. 0.066s). But for other input commands like locate, find, reading from a file (tr \\n \\0 <file) or similar, you have to work with xargs like this.

If you are looking for a range of columns, you can try this:

df.iloc[7:] = df.iloc[7:].astype(float)

The examples above will convert type to be float, for all the columns begin with the 7th to the end. You of course can use different type or different range.

I think this is useful when you have a big range of columns to convert and a lot of rows. It doesn't make you go over each row by yourself - I believe numpy do it more efficiently.

This is useful only if you know that all the required columns contain numbers only - it will not change "bad values" (like string) to be NaN for you.

To help guard against SQL injection, I normally try to use functions wherever possible. In this case, you could do:

...
SET @TableName = '<[db].><[schema].>tblEmployees'
SET @TableID   = OBJECT_ID(TableName) --won't resolve if malformed/injected.
...
SET @SQLQuery = 'SELECT * FROM ' + OBJECT_NAME(@TableID) + ' WHERE EmployeeID = @EmpID' 

On windows 10 run cmd.exe with admin rights then type :

1) cd \Python27\scripts

2) pip install requests

It should work. My case was with python 2.7

If your .so file is in elf format, you can use readelf program to extract symbol information from the binary. This command will give you the symbol table:

readelf -Ws /usr/lib/libexample.so

You only should extract those that are defined in this .so file, not in the libraries referenced by it. Seventh column should contain a number in this case. You can extract it by using a simple regex:

readelf -Ws /usr/lib/libstdc++.so.6 | grep '^\([[:space:]]\+[^[:space:]]\+\)\{6\}[[:space:]]\+[[:digit:]]\+'

or, as proposed by Caspin,:

readelf -Ws /usr/lib/libstdc++.so.6 | awk '{print $8}';

Assuming your controller's action method is something like this:

public ActionResult AllCategories(int id = 0)
{
    return View(db.Categories.Include(p => p.Products).ToList());
}

Modify your models to be something like this:

public class Product
{
    [Key]
    public int ID { get; set; }
    public int CategoryID { get; set; }
    //new code
    public virtual Category Category { get; set; }
    public string Title { get; set; }
    public string Description { get; set; }
    public string Path { get; set; }

    //remove code below
    //public virtual ICollection<Category> Categories { get; set; }
}

public class Category
{
    [Key]
    public int CategoryID { get; set; }
    public string Name { get; set; }
    //new code
    public virtual ICollection<Product> Products{ get; set; }
}

Then your since now the controller takes in a Category as Model (instead of a Product):

foreach (var category in Model)
{
    <h3><u>@category.Name</u></h3>
    <div>
        <ul>    
            @foreach (var product in Model.Products)
            {
                // cut for brevity, need to add back more code from original
                <li>@product.Title</li>
            }
        </ul>
    </div>
}

UPDATED: Add ToList() to the controller return statement.

Here is a function that will allow you to remove all localStorage items with exceptions. You will need jQuery for this function. You can download the gist.

You can call it like this

let clearStorageExcept = function(exceptions) {
  let keys = [];
  exceptions = [].concat(exceptions); // prevent undefined

  // get storage keys
  $.each(localStorage, (key) => {
    keys.push(key);
  });

  // loop through keys
  for (let i = 0; i < keys.length; i++) {
    let key = keys[i];
    let deleteItem = true;

    // check if key excluded
    for (let j = 0; j < exceptions.length; j++) {
      let exception = exceptions[j];
      if (key == exception) {
        deleteItem = false;
      }
    }

    // delete key
    if (deleteItem) {
      localStorage.removeItem(key);
    }
  }
};

Without converting to list and probably the simplest way would be something like below. This may be useful during a interview when they ask not to use sets

a=[1,2,3,3,3]
dup=[]
for each in a:
  if each not in dup:
    dup.append(each)
print(dup)

======= else to get 2 separate lists of unique values and duplicate values

a=[1,2,3,3,3]
uniques=[]
dups=[]

for each in a:
  if each not in uniques:
    uniques.append(each)
  else:
    dups.append(each)
print("Unique values are below:")
print(uniques)
print("Duplicate values are below:")
print(dups)

in older bash (or in sh) that does not support declare -A, following style can be used to emulate key/value

# key
env=staging


# values
image_dev=gcr.io/abc/dev
image_staging=gcr.io/abc/stage
image_production=gcr.io/abc/stable

img_var_name=image_$env

# active_image=${!var_name}
active_image=$(eval "echo \$$img_var_name")

echo $active_image

You can watch your container element using the useRef hook. Note that you need to watch the ref's current value specifically, otherwise it won't work.

Example:

  const containerRef = useRef();
  const { current } = containerRef;

  useEffect(setLinksData, [current]);

return (
    <div ref={containerRef}>
      // your child elements...
    </div>
)

Another way to do it if you "own" the module is to use module_function.

module UsefulThings
  def a
    puts "aaay"
  end
  module_function :a

  def b
    puts "beee"
  end
end

def test
  UsefulThings.a
  UsefulThings.b # Fails!  Not a module method
end

test

If you create the machine account on the DC first, then you can change the name and join the domain in one reboot.

Turns out it is possible to enter a host name directly into the playbook, so running the playbook with hosts: imac-2.local will work fine. But it's kind of clunky.

A better solution might be defining the playbook's hosts using a variable, then passing in a specific host address via --extra-vars:

# file: user.yml  (playbook)
---
- hosts: '{{ target }}'
  user: ...

Running the playbook:

ansible-playbook user.yml --extra-vars "target=imac-2.local"

If {{ target }} isn't defined, the playbook does nothing. A group from the hosts file can also be passed through if need be. Overall, this seems like a much safer way to construct a potentially destructive playbook.

Playbook targeting a single host:

$ ansible-playbook user.yml --extra-vars "target=imac-2.local" --list-hosts

playbook: user.yml

  play #1 (imac-2.local): host count=1
    imac-2.local

Playbook with a group of hosts:

$ ansible-playbook user.yml --extra-vars "target=office" --list-hosts

playbook: user.yml

  play #1 (office): host count=3
    imac-1.local
    imac-2.local
    imac-3.local

Forgetting to define hosts is safe!

$ ansible-playbook user.yml --list-hosts

playbook: user.yml

  play #1 ({{target}}): host count=0

Annotate your util classes with @Ignore. This will cause JUnit not to try and run them as tests.

You can use the following solution to accomplish your goal:

struct student 
{
    char name[20];
    char country[20];
};
void main()
{
    struct student S={"Wolverine","America"};
    struct student X;
    X=S;
    printf("%s%s",X.name,X.country);
}

One use of reinterpret_cast is if you want to apply bitwise operations to (IEEE 754) floats. One example of this was the Fast Inverse Square-Root trick:

https://en.wikipedia.org/wiki/Fast_inverse_square_root#Overview_of_the_code

It treats the binary representation of the float as an integer, shifts it right and subtracts it from a constant, thereby halving and negating the exponent. After converting back to a float, it's subjected to a Newton-Raphson iteration to make this approximation more exact:

float Q_rsqrt( float number )
{
    long i;
    float x2, y;
    const float threehalfs = 1.5F;

    x2 = number * 0.5F;
    y  = number;
    i  = * ( long * ) &y;                       // evil floating point bit level hacking
    i  = 0x5f3759df - ( i >> 1 );               // what the deuce? 
    y  = * ( float * ) &i;
    y  = y * ( threehalfs - ( x2 * y * y ) );   // 1st iteration
//  y  = y * ( threehalfs - ( x2 * y * y ) );   // 2nd iteration, this can be removed

    return y;
}

This was originally written in C, so uses C casts, but the analogous C++ cast is the reinterpret_cast.

Store username and password in .git-credentials

.git-credentials is where your username and password(access token) is stored when you run git config --global credential.helper store, which is what other answers suggest, and then type in your username and password or access token:

https://${username_or_access_token}:${password_or_access_token}@github.com

So, in order to save the username and password(access token):

git config —-global credential.helper store
echo “https://${username}:${password_or_access_token}@github.com“ > ~/.git-credentials

This is very useful for github robot, e.g. to solve Chain automated builds in the same docker repository by having rules for different branch and then trigger it by pushing to it in post_push hooker in docker hub.

An example of this can be seen here in stackoverflow.

document.getElementById("tblBlah").rows[i].columns[j].innerHTML;

Should be:

document.getElementById("tblBlah").rows[i].cells[j].innerHTML;

But I get the distinct impression that the row/cell you need is the one clicked by the user. If so, the simplest way to achieve this would be attaching an event to the cells in your table:

function alertInnerHTML(e)
{
    e = e || window.event;//IE
    alert(this.innerHTML);
}

var theTbl = document.getElementById('tblBlah');
for(var i=0;i<theTbl.length;i++)
{
    for(var j=0;j<theTbl.rows[i].cells.length;j++)
    {
        theTbl.rows[i].cells[j].onclick = alertInnerHTML;
    }
}

That makes all table cells clickable, and alert it's innerHTML. The event object will be passed to the alertInnerHTML function, in which the this object will be a reference to the cell that was clicked. The event object offers you tons of neat tricks on how you want the click event to behave if, say, there's a link in the cell that was clicked, but I suggest checking the MDN and MSDN (for the window.event object)

You can make a simple setInterval.

function someJsClass()_x000D_
{_x000D_
  var _resizeInterval = null;_x000D_
  var _lastHeight = 0;_x000D_
  var _lastWidth = 0;_x000D_
  _x000D_
  this.Initialize = function(){_x000D_
    var _resizeInterval = setInterval(_resizeIntervalTick, 200);_x000D_
  };_x000D_
  _x000D_
  this.Stop = function(){_x000D_
    if(_resizeInterval != null)_x000D_
      clearInterval(_resizeInterval);_x000D_
  };_x000D_
  _x000D_
  var _resizeIntervalTick = function () {_x000D_
    if ($(yourDiv).width() != _lastWidth || $(yourDiv).height() != _lastHeight) {_x000D_
      _lastWidth = $(contentBox).width();_x000D_
      _lastHeight = $(contentBox).height();_x000D_
      DoWhatYouWantWhenTheSizeChange();_x000D_
    }_x000D_
  };_x000D_
}_x000D_
_x000D_
var class = new someJsClass();_x000D_
class.Initialize();

EDIT:

This is a example with a class. But you can do something easiest.

When you send bytes from a buffer with a normal TCP socket, the send function returns the number of bytes of the buffer that were sent. If it is a non-blocking socket or a non-blocking send then the number of bytes sent may be less than the size of the buffer. If it is a blocking socket or blocking send, then the number returned will match the size of the buffer but the call may block. With WebSockets, the data that is passed to the send method is always either sent as a whole "message" or not at all. Also, browser WebSocket implementations do not block on the send call.

But there are more important differences on the receiving side of things. When the receiver does a recv (or read) on a TCP socket, there is no guarantee that the number of bytes returned corresponds to a single send (or write) on the sender side. It might be the same, it may be less (or zero) and it might even be more (in which case bytes from multiple send/writes are received). With WebSockets, the recipient of a message is event-driven (you generally register a message handler routine), and the data in the event is always the entire message that the other side sent.

Note that you can do message based communication using TCP sockets, but you need some extra layer/encapsulation that is adding framing/message boundary data to the messages so that the original messages can be re-assembled from the pieces. In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message. The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message.

Using the size attribute is the most practical solution, however there are quirks when it is applied to select elements with only two or three options.

• Setting the size attribute value to "0" or "1" will mostly render a default select element (dropdown).
• Setting the size attribute to a value greater than "1" will mostly render a selection list with a height capable of displaying at least four items. This also applies to lists with only two or three items, leading to unintended white-space.

Simple JavaScript can be used to set the size attribute to the correct value automatically, e.g. see this fiddle.

$(function() {
    $("#autoheight").attr("size", parseInt($("#autoheight option").length)); 
});

As mentioned above, this solution does not solve the issue when there are only two or three options.

If you have a List<List<int>> k you can do

List<int> flatList= k.SelectMany( v => v).ToList();

set variable as

@JsonIgnore

This allows variable to get skipped by json serializer

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

Below command solved the issue:

npm config set strict-ssl false

My requirements were a bit stricter:

• I had to retain case info (the strings are paths to files displayed to the user, but it's a windows app so internally all operations must be case insensitive)
• I needed keys to be as small as possible (it did make a difference in memory performance, chopped off 110 mb out of 370). This meant that caching lowercase version of keys is not an option.
• I needed creation of the data structures to be as fast as possible (again made a difference in performance, speed this time). I had to go with a builtin

My initial thought was to substitute our clunky Path class for a case insensitive unicode subclass - but:

• proved hard to get that right - see: A case insensitive string class in python
• turns out that explicit dict keys handling makes code verbose and messy - and error prone (structures are passed hither and thither, and it is not clear if they have CIStr instances as keys/elements, easy to forget plus some_dict[CIstr(path)] is ugly)

So I had finally to write down that case insensitive dict. Thanks to code by @AaronHall that was made 10 times easier.

Implicit vs explicit is still a problem, but once dust settles, renaming of attributes/variables to start with ci (and a big fat doc comment explaining that ci stands for case insensitive) I think is a perfect solution - as readers of the code must be fully aware that we are dealing with case insensitive underlying data structures. This will hopefully fix some hard to reproduce bugs, which I suspect boil down to case sensitivity.

Comments/corrections welcome :)

Use somethings like this :

public static class PropertyExtension{       

   public static void SetPropertyValue(this object p_object, string p_propertyName, object value)
   {
    PropertyInfo property = p_object.GetType().GetProperty(p_propertyName);
    property.SetValue(p_object, Convert.ChangeType(value, property.PropertyType), null);
   }
}

or

public static class PropertyExtension{       

   public static void SetPropertyValue(this object p_object, string p_propertyName, object value)
   {
    PropertyInfo property = p_object.GetType().GetProperty(p_propertyName);
    Type t = Nullable.GetUnderlyingType(property.PropertyType) ?? property.PropertyType;
    object safeValue = (value == null) ? null : Convert.ChangeType(value, t);

    property.SetValue(p_object, safeValue, null);
   }
}

You can use SysInternals NTFSInfo by Mark Russinovich from the command line and it converts fsutil fsinfo ntfsinfo into more readable information, especially MFT Table info.

Got the same problem, found the following bug report in SQL Server 2012 If still relevant see conditions that cause the issue - there are some workarounds there as well (didn't try though). Failover or Restart Results in Reseed of Identity

I'm not exactly sure what's causing this. You can try looking in your socket.py (mine is a different version, so line numbers from the trace don't match, and I'm afraid some other details might not match as well).

Anyway, it seems like a good practice to put your url fetching code in a try: ... except: ... block, and handle this with a short pause and a retry. The URL you're trying to fetch may be down, or too loaded, and that's stuff you'll only be able to handle in with a retry anyway.

Change "Data" to whatever sheet name you're testing for...

On Error Resume Next 

Set DataSheet = Sheets("Data")

If DataSheet Is Nothing Then

     Sheets.Add(after:=ActiveSheet).Name = "Data"
     ''or whatever alternate code you want to execute''
End If

On Error GoTo 0

I think you can use date() function to achive this

$date = '19:24:15 06/13/2013'; 
echo date('h:i:s a m/d/Y', strtotime($date));

This will output

07:24:15 pm 06/13/2013

Live Sample

h is used for 12 digit time
i stands for minutes
s seconds
a will return am or pm (use in uppercase for AM PM)
m is used for months with digits
d is used for days in digit
Y uppercase is used for 4 digit year (use it lowercase for two digit)

Updated

This is with DateTime

$date = new DateTime('19:24:15 06/13/2013');
echo $date->format('h:i:s a m/d/Y') ;

Here is the complete process to create a local repo and push the changes to new remote branch

1. Creating local repository:-

   Initially user may have created the local git repository.

   $ git init :- This will make the local folder as Git repository,

2. Link the remote branch:-

   Now challenge is associate the local git repository with remote master branch.

   $ git remote add RepoName RepoURL

   usage: git remote add []

3. Test the Remote

   $ git remote show --->Display the remote name

   $ git remote -v --->Display the remote branches

4. Now Push to remote

   $git add . ----> Add all the files and folder as git staged'

   $git commit -m "Your Commit Message" - - - >Commit the message

   $git push - - - - >Push the changes to the upstream

Yes Jython does this, but it may or may not be what you want

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.activity_add_customer, container, false);
        setHasOptionsMenu(true);
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.menu_sample, menu);
    super.onCreateOptionsMenu(menu,inflater);

maybe you need to set your window-size dimension. just like:

options = webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
options.add_argument('--window-size=1920x1080');

browser = webdriver.Chrome(options=options,executable_path = './chromedriver')

if also not working, try increase window-size dimension.

The let command supports most of the basic operators one would need:

let a=b==5?c:d;

Naturally, this works only for assigning variables; it cannot execute other commands.

First, please do not use extract(), it can be a security problem because it is easy to manipulate POST parameters

In addition, you don't have to use variable variable names (that sounds odd), instead:

foreach($_POST as $key => $value) {
  echo "POST parameter '$key' has '$value'";
}

To ensure that you have only parameters beginning with 'item_name' you can check it like so:

$param_name = 'item_name';
if(substr($key, 0, strlen($param_name)) == $param_name) {
  // do something
}

You are just returning a memory address, it's allowed but probably an error.

Yes if you try to dereference that memory address you will have undefined behavior.

int * ref () {

 int tmp = 100;
 return &tmp;
}

int main () {

 int * a = ref();
 //Up until this point there is defined results
 //You can even print the address returned
 // but yes probably a bug

 cout << *a << endl;//Undefined results
}

So I did some speed comparisons to get the fastest way. List comprehensions are indeed very fast. The only way to get close is to avoid bytecode getting exectuded during construction of the list. My first attempt was the following method, which would appear to be faster in principle:

l = [[]]
for _ in range(n): l.extend(map(list,l))

(produces a list of length 2**n, of course) This construction is twice as slow as the list comprehension, according to timeit, for both short and long (a million) lists.

My second attempt was to use starmap to call the list constructor for me, There is one construction, which appears to run the list constructor at top speed, but still is slower, but only by a tiny amount:

from itertools import starmap
l = list(starmap(list,[()]*(1<<n)))

Interesting enough the execution time suggests that it is the final list call that is makes the starmap solution slow, since its execution time is almost exactly equal to the speed of:

l = list([] for _ in range(1<<n))

My third attempt came when I realized that list(()) also produces a list, so I tried the apperently simple:

l = list(map(list, [()]*(1<<n)))

but this was slower than the starmap call.

Conclusion: for the speed maniacs: Do use the list comprehension. Only call functions, if you have to. Use builtins.

You should have sdiff for side-by-side merge of file differences. Take a read of man sdiff for the full story.

codaddict's solution works fine, but this one is a bit more efficient: (Python syntax)

password = re.compile(r"""(?#!py password Rev:20160831_2100)
    # Validate password: 2 upper, 1 special, 2 digit, 1 lower, 8 chars.
    ^                        # Anchor to start of string.
    (?=(?:[^A-Z]*[A-Z]){2})  # At least two uppercase.
    (?=[^!@#$&*]*[!@#$&*])   # At least one "special".
    (?=(?:[^0-9]*[0-9]){2})  # At least two digit.
    .{8,}                    # Password length is 8 or more.
    $                        # Anchor to end of string.
    """, re.VERBOSE)

The negated character classes consume everything up to the desired character in a single step, requiring zero backtracking. (The dot star solution works just fine, but does require some backtracking.) Of course with short target strings such as passwords, this efficiency improvement will be negligible.

There is one important thing to mention:

$("#txt_name").val();

will return the current real value of a text field, for example if the user typed something there after a page load.

But:

$("#txt_name").attr('value')

will return value from DOM/HTML.

public boolean FileExists(String fname) {
        File file = getBaseContext().getFileStreamPath(fname);
        return file.exists();
}

Here's a solution that uses more modern syntax and is less verbose than the ones already provided:

const canvas = document.querySelector("canvas");
const ctx = canvas.getContext("2d");
const video = document.querySelector("video");

video.addEventListener('play', () => {
  function step() {
    ctx.drawImage(video, 0, 0, canvas.width, canvas.height)
    requestAnimationFrame(step)
  }
  requestAnimationFrame(step);
})

Some useful links:

• MDN Documentation for window.requestAnimationFrame()
• Can I use requestAnimationFrame?

An example, just to make this a 15 seconds answer -

Say you have "styles.xaml" in a WPF library named "common" and you want to use it from your main application project:

1. Add a reference from the main project to "common" project
2. Your app.xaml should contain:

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/Common;component/styles.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

  await new Promise(resolve => setTimeout(resolve, 2000));

make sure your calling function is async

verified and working fine

Coffeescript doesn't support javascript ternary operator. Here is the reason from the coffeescript author:

I love ternary operators just as much as the next guy (probably a bit more, actually), but the syntax isn't what makes them good -- they're great because they can fit an if/else on a single line as an expression.

Their syntax is just another bit of mystifying magic to memorize, with no analogue to anything else in the language. The result being equal, I'd much rather have if/elses always look the same (and always be compiled into an expression).

So, in CoffeeScript, even multi-line ifs will compile into ternaries when appropriate, as will if statements without an else clause:

if sunny   
  go_outside() 
else   
  read_a_book().

if sunny then go_outside() else read_a_book()

Both become ternaries, both can be used as expressions. It's consistent, and there's no new syntax to learn. So, thanks for the suggestion, but I'm closing this ticket as "wontfix".

Please refer to the github issue: https://github.com/jashkenas/coffeescript/issues/11#issuecomment-97802

I wanted to replicate Unix/Linux's cp -r as closely as possible. I came up with the following:

xcopy /e /k /h /i srcdir destdir

Flag explanation:

/e Copies directories and subdirectories, including empty ones.
/k Copies attributes. Normal Xcopy will reset read-only attributes.
/h Copies hidden and system files also.
/i If destination does not exist and copying more than one file, assume destination is a directory.

I made the following into a batch file (cpr.bat) so that I didn't have to remember the flags:

xcopy /e /k /h /i %*

Usage: cpr srcdir destdir

You might also want to use the following flags, but I didn't:
/q Quiet. Do not display file names while copying.
/b Copies the Symbolic Link itself versus the target of the link. (requires UAC admin)
/o Copies directory and file ACLs. (requires UAC admin)

Of course you can, say for example, you want to use the DescriptionAttribue on your enum values:

using System.ComponentModel.DataAnnotations;

public enum Duration 
{ 
    [Description("Eight hours")]
    Day,

    [Description("Five days")]
    Week,

    [Description("Twenty-one days")] 
    Month 
}

Now you want to be able to do something like:

Duration duration = Duration.Week;
var description = duration.GetDescription(); // will return "Five days"

Your extension method GetDescription() can be written as follows:

using System.ComponentModel;
using System.Reflection;

public static string GetDescription(this Enum value)
{
    FieldInfo fieldInfo = value.GetType().GetField(value.ToString());
    if (fieldInfo == null) return null;
    var attribute = (DescriptionAttribute)fieldInfo.GetCustomAttribute(typeof(DescriptionAttribute));
    return attribute.Description;
}

I was also a bit confused between adjustResize and adjustPan when I was a beginner. The definitions given above are correct.
AdjustResize : Main activity's content is resized to make room for soft input i.e keyboard
AdjustPan : Instead of resizing overall contents of the window, it only pans the content so that the user can always see what is he typing
AdjustNothing : As the name suggests nothing is resized or panned. Keyboard is opened as it is irrespective of whether it is hiding the contents or not.

I have a created a example for better understanding

you can then adapt then format with elements format foundable here

Replace bigint(20) not null auto_increment by bigserial not null and datetime by timestamp

I faced this problem and this is how I solved it.

1) Delete all the migration records from your app's migration directory. These are files named 0001_,0002_,0003_ etc. Be careful as to not delete the _init__.py file.

2) Delete the db.sqlite3 file. It will be regenerated later.

Now, run the following commands:

python manage.py makemigrations appname
python manage.py migrate

Be sure to write the name of your app after makemigrations. You might have to create a superuser to access your database again. Do so by the following

python manage.py createsuperuser

By printing multiple values separated by a comma:

print "I have", card.price

The print statement will output each expression separated by spaces, followed by a newline.

If you need more complex formatting, use the ''.format() method:

print "I have: {0.price}".format(card)

or by using the older and semi-deprecated % string formatting operator.

"returning a reference is evil because, simply [as I understand] it makes it easier to miss deleting it"

Not true. Returning a reference does not imply ownership semantics. That is, just because you do this:

Value& v = thing->getTheValue();

...does not mean you now own the memory referred to by v;

However, this is horrible code:

int& getTheValue()
{
   return *new int;
}

If you are doing something like this because "you don't require a pointer on that instance" then: 1) just dereference the pointer if you need a reference, and 2) you will eventually need the pointer, because you have to match a new with a delete, and you need a pointer to call delete.

I think you're confused about what binary is. Binary and decimal are just different representations of a number - e.g. 101 base 2 and 5 base 10 are the same number. The operations add, subtract, and compare operate on numbers - 101 base 2 == 5 base 10 and addition is the same logical operation no matter what base you're working in.

zero(myarray); is all you need in C++.

Just add this to a header:

template<typename T, size_t SIZE> inline void zero(T(&arr)[SIZE]){
    memset(arr, 0, SIZE*sizeof(T));
}

For example, to set the background to your favorite/Branding color

Add Below Meta property to your HTML code in HEAD Section

Hiding Safari User Interface Components

Set the apple-mobile-web-app-capable meta tag to yes to turn on standalone mode. For example, the following HTML displays web content using standalone mode.

<meta name="apple-mobile-web-app-capable" content="yes">

Changing the Status Bar Appearance

You can change the appearance of the default status bar to either black or black-translucent. With black-translucent, the status bar floats on top of the full screen content, rather than pushing it down. This gives the layout more height, but obstructs the top. Here’s the code required:

<meta name="apple-mobile-web-app-status-bar-style" content="black">

For more on status bar appearance, see apple-mobile-web-app-status-bar-style.

For Example:

In my case, some domains worked, while some did not. Adding a reference to my organization's proxy Url in my web.config fixed the issue.

<system.net>
    <defaultProxy useDefaultCredentials="true">

    </defaultProxy>
</system.net>

What do you mean by "not always reliable"? If the system succeeds in setting your socket non non-blocking, it will be non-blocking. Socket operations will return EWOULDBLOCK if they would block need to block (e.g. if the output buffer is full and you're calling send/write too often).

This forum thread has a few good points when working with non-blocking calls.

I was the same when, in a fragment, I wanted to populate a ListView (in a single TextView) with the mac address of BLE devices scanned over some time.

What I did was this:

public class Fragment01 extends android.support.v4.app.Fragment implements ...
{
    private ListView                listView;
    private ArrayAdapter<String>    arrayAdapter_string;

...

@Override
public void onActivityCreated(Bundle savedInstanceState)
{
    ...
    this.listView= (ListView) super.getActivity().findViewById(R.id.fragment01_listView);
    ...
    this.arrayAdapter_string= new ArrayAdapter<String>(super.getActivity(), R.layout.dispositivo_ble_item, R.id.fragment01_item_textView_titulo);
    this.listView.setAdapter(this.arrayAdapter_string);
}


@Override
public void onLeScan(BluetoothDevice device, int rssi, byte[] scanRecord)
{
    ...
    super.getActivity().runOnUiThread(new RefreshListView(device));
}


private class RefreshListView implements Runnable
{
    private BluetoothDevice bluetoothDevice;

    public RefreshListView(BluetoothDevice bluetoothDevice)
    {
        this.bluetoothDevice= bluetoothDevice;
    }

    @Override
    public void run()
    {
        Fragment01.this.arrayAdapter_string.add(new String(bluetoothDevice.toString()));
        Fragment01.this.arrayAdapter_string.notifyDataSetChanged();
    }
}

Then the ListView began to dynamically populate with the mac address of the devices found.

If the long string to multiple lines confuses you. Then you may install mz-tools addin which is a freeware and has the utility which splits the line for you.

Download Mz-tools

If your string looks like below

SqlQueryString = "Insert into Employee values(" & txtEmployeeNo.Value & "','" & txtContractStartDate.Value & "','" & txtSeatNo.Value & "','" & txtFloor.Value & "','" & txtLeaves.Value & "')"

Simply select the string > right click on VBA IDE > Select MZ-tools > Split Lines

There is an alternative approach I used when I couldn't rely on the EXCEPTION block at the bottom of my procedure. I had variables declared at the beginning:

my_value VARCHAR := 'default';
number_rows NUMBER := 0;
.
.
.
SELECT count(*) FROM TABLE INTO number_rows (etc.)

IF number_rows > 0 -- Then obtain my_value with a query or constant, etc.
END IF;

Try this function. I just wrote it and haven't had much of a chance to test it, but my preliminary tests are promising.

        }
        else

            if (processElement.IndexOf(":") > -1)
            {
                arrElementData = processElement.Replace(": \"", ":").Replace("\",", "").Replace("\"", "").Split(':');
                newNode = returnXmlDoc.CreateElement(arrElementData[0]);
                for (int i = 1; i < arrElementData.Length; i++)
                {
                    newNode.InnerText += arrElementData[i];
                }

                appendToNode.AppendChild(newNode);
            }
        }
    }

    return returnXmlDoc;
}

The best place to find answers to general (and somewhat easy questions) such as this is to read up on PHP docs. Specifically in your case you can read more on objects. You can store stdObject and instantiated objects within an array. In fact, there is a process known as 'hydration' which populates the member variables of an object with values from a database row, then the object is stored in an array (possibly with other objects) and returned to the calling code for access.

-- Edit --

class Car
{
    public $color;
    public $type;
}

$myCar = new Car();
$myCar->color = 'red';
$myCar->type = 'sedan';

$yourCar = new Car();
$yourCar->color = 'blue';
$yourCar->type = 'suv';

$cars = array($myCar, $yourCar);

foreach ($cars as $car) {
    echo 'This car is a ' . $car->color . ' ' . $car->type . "\n";
}

It's a sort of dummy table with a single record used for selecting when you're not actually interested in the data, but instead want the results of some system function in a select statement:

e.g. select sysdate from dual;

See http://www.adp-gmbh.ch/ora/misc/dual.html

You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start(). The headers will be sent automatically when any HTML is output.

Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.

Move the session_start() to the top of your document :

<?php    session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php';    // more PHP code here. 

It took us a day to resolve this problem. The solution is forcing your webservice to use version 11.0.0 in your web.config file.

try this code to zoom the whole page in fireFox

-moz-transform: scale(2);

if I am using this code, the whole page scaled with y and x scroll not properly zoom

so Sorry to say fireFox not working well using "-moz-transform: scale(2);"

Simply you can't zoom your page using css in fireFox

Selecting a HTTP response code is quite an easy task and can be described by simple rules. The only tricky part which is often forgotten is paragraph 6.5 from RFC 7231:

Except when responding to a HEAD request, the server SHOULD send a representation containing an explanation of the error situation, and whether it is a temporary or permanent condition.

Rules are as following:

1. If request was successful, then return 2xx code (3xx for redirect). If there was an internal logic error on a server, then return 5xx. If there is anything wrong in client request, then return 4xx code.
2. Look through available response code from selected category. If one of them has a name which matches well to your situation, you can use it. Otherwise just fallback to x00 code (200, 400, 500). If you doubt, fallback to x00 code.
3. Return error description in response body. For 4xx codes it must contain enough information for client developer to understand the reason and fix the client. For 5xx because of security reasons no details must be revealed.
4. If client needs to distinguish different errors and have different reaction depending on it, define a machine readable and extendible error format and use it everywhere in your API. It is good practice to make that from very beginning.
5. Keep in mind that client developer may do strange things and try to parse strings which you return as human readable description. And by changing the strings you will break such badly written clients. So always provide machine readable description and try to avoid reporting additional information in text.

So in your case I'd returned 400 error and something like this if "Roman" is obtained from user input and client must have specific reaction:

{
    "error_type" : "unsupported_resource",
    "error_description" : "\"Roman\" is not supported"
}

or a more generic error, if such situation is a bad logic error in a client and is not expected, unless developer made something wrong:

{
    "error_type" : "malformed_json",
    "error_description" : "\"Roman\" is not supported for \"requestedResource\" field"
}

I don't see any problem, unless you are not managing them using a connection pool.

If you use connection pool, these connections are re-used instead of initiating new connections. so basically, leaving open connections and re-use them it is less problematic than re-creating them each time.

Short and fast Base64 JavaScript Decode Function without Failsafe:

function decode_base64 (s)
{
    var e = {}, i, k, v = [], r = '', w = String.fromCharCode;
    var n = [[65, 91], [97, 123], [48, 58], [43, 44], [47, 48]];

    for (z in n)
    {
        for (i = n[z][0]; i < n[z][1]; i++)
        {
            v.push(w(i));
        }
    }
    for (i = 0; i < 64; i++)
    {
        e[v[i]] = i;
    }

    for (i = 0; i < s.length; i+=72)
    {
        var b = 0, c, x, l = 0, o = s.substring(i, i+72);
        for (x = 0; x < o.length; x++)
        {
            c = e[o.charAt(x)];
            b = (b << 6) + c;
            l += 6;
            while (l >= 8)
            {
                r += w((b >>> (l -= 8)) % 256);
            }
         }
    }
    return r;
}

This is the solution which can avoid using function:

alias addone='{ num=$(cat -); echo "input: $num"; echo "result:$(($num+1))"; }<<<'

test result

addone 200
input: 200
result:201

REST vs. SOAP Web Services

I am seeing a lot of new web services are implemented using a REST style architecture these days rather than a SOAP one. Lets step back a second and explain what REST is.

What is a REST web service?

The acronym REST stands for representational state transfer, and this basically means that each unique URL is a representation of some object. You can get the contents of that object using an HTTP GET, to delete it, you then might use a POST, PUT, or DELETE to modify the object (in practice most of the services use a POST for this).

Who's using REST?

All of Yahoo's web services use REST, including Flickr and Delicious.

APIs use it, pubsub, bloglines, Technorati, and both eBay, and Amazon have web services for both REST and SOAP.

Who's using SOAP?

Google seams to be consistent in implementing their web services to use SOAP, with the exception of Blogger, which uses XML-RPC. You will find SOAP web services in lots of enterprise software as well.

REST vs. SOAP

As you may have noticed the companies I mentioned that are using REST APIs haven't been around for very long, and their APIs came out this year mostly. So REST is definitely the trendy way to create a web service, if creating web services could ever be trendy (lets face it you use soap to wash, and you rest when your tired). The main advantages of REST web services are:

• Lightweight - not a lot of extra XML markup Human Readable Results

• Easy to build - no toolkits required. SOAP also has some advantages:

Easy to consume - sometimes Rigid - type checking, adheres to a contract Development tools For consuming web services, its sometimes a toss up between which is easier. For instance Google's AdWords web service is really hard to consume (in ColdFusion anyway), it uses SOAP headers, and a number of other things that make it kind of difficult. On the converse, Amazon's REST web service can sometimes be tricky to parse because it can be highly nested, and the result schema can vary quite a bit based on what you search for.

Whichever architecture you choose make sure its easy for developers to access it, and well documented.

This works:

<html>
<head></head>
<body>

<object type="text/html" id="htmlFrame" style="border: none;" standby="loading" width="100%"></object> 

<script type="text/javascript">
  var element = document.getElementById("htmlFrame"); 
  element.setAttribute("data", "attributeValue"); 
</script>

</body>
</html>

If you put this in a file, open in it a web browser, the javascript will execute and and the "data" attribute + value will be added to the object element.

Note: If you simply look at the HTML source, you wil NOT see the attribute. This is because the browser is showing you the static source sent by the webserver, NOT the dynamically rendered DOM. To inspect the DOM, use a tool like Firebug. This will show you what DOM the browser has rendered, and you will be able to see the added attribute.

Using Firefox + Firebug or Google Chrome, you can right click on a part of a page and do "Inspect Element". This will bring up a view of the rendered DOM.

I ran into this issue as well, but in order to use a safe pipe in my angular module, I installed the safe-pipe npm package, which you can find here. FYI, this worked in Angular 9.1.3, I haven't tried this in any other versions of Angular. Here's how you add it step by step:

1. Install the package via npm install safe-pipe or yarn add safe-pipe. This will store a reference to it in your dependencies in the package.json file, which you should already have from starting a new Angular project.

2. Add SafePipeModule module to NgModule.imports in your Angular module file like so:

   import { SafePipeModule } from 'safe-pipe';
   
   @NgModule({
       imports: [ SafePipeModule ]
   })
   export class AppModule { }
   
   

3. Add the safe pipe to an element in the template for the Angular component you are importing into your NgModule this way:

<element [property]="value | safe: sanitizationType"></element>

4. Here are some specific examples of the safePipe in an html element:

<div [style.background-image]="'url(' + pictureUrl + ')' | safe: 'style'" class="pic bg-pic"></div>
<img [src]="pictureUrl | safe: 'url'" class="pic" alt="Logo">
<iframe [src]="catVideoEmbed | safe: 'resourceUrl'" width="640" height="390"></iframe>
<pre [innerHTML]="htmlContent | safe: 'html'"></pre>

You are using improper syntax. If you read the docs mysqli_query() you will find that it needs two parameter.

mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )

mysql $link generally means, the resource object of the established mysqli connection to query the database.

So there are two ways of solving this problem

mysqli_query();

$myConnection= mysqli_connect("$db_host","$db_username","$db_pass", "mrmagicadam") or die ("could not connect to mysql"); 
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysqli_query($myConnection, $sqlCommand) or die(mysqli_error($myConnection));

Or, Using mysql_query() (This is now obselete)

$myConnection= mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("mrmagicadam") or die ("no database");        
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysql_query($sqlCommand) or die(mysql_error());

As pointed out in the comments, be aware of using die to just get the error. It might inadvertently give the viewer some sensitive information .

Sample program to mouse hover using Selenium java WebDriver :

public class Mhover {
    public static void main(String[] args){
       WebDriver driver = new FirefoxDriver();
       driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
       driver.get("http://www.google.com");
       WebElement ele = driver.findElement(By.id("gbqfba"));
       Actions action = new Actions(driver);
       action.moveToElement(ele).build().perform();
    }
}

OK turns out what you really want is this: http://inputsimulator.codeplex.com/

Which has done all the hard work of exposing the Win32 SendInput methods to C#. This allows you to directly send the windows key. This is tested and works:

InputSimulator.SimulateModifiedKeyStroke(VirtualKeyCode.LWIN, VirtualKeyCode.VK_E);

Note however that in some cases you want to specifically send the key to the application (such as ALT+F4), in which case use the Form library method. In others, you want to send it to the OS in general, use the above.

Old

Keeping this here for reference, it will not work in all operating systems, and will not always behave how you want. Note that you're trying to send these key strokes to the app, and the OS usually intercepts them early. In the case of Windows 7 and Vista, too early (before the E is sent).

SendWait("^({ESC}E)") or Send("^({ESC}E)")

Note from here: http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.aspx

To specify that any combination of SHIFT, CTRL, and ALT should be held down while several other keys are pressed, enclose the code for those keys in parentheses. For example, to specify to hold down SHIFT while E and C are pressed, use "+(EC)". To specify to hold down SHIFT while E is pressed, followed by C without SHIFT, use "+EC".

Note that since you want ESC and (say) E pressed at the same time, you need to enclose them in brackets.

1. Find the process id [PS ID]
2. Execute jcmd [PS ID] Thread.print

You're looking for case:

case when action = 2 and state = 0 then 1 else 0 end as state

MySQL has an if syntax (if(action=2 and state=0, 1, 0)), but case is more universal.

Note that the as state there is just aliasing the column. I'm assuming this is in the column list of your SQL query.

def int2base(a, base, numerals="0123456789abcdefghijklmnopqrstuvwxyz"):
    baseit = lambda a=a, b=base: (not a) and numerals[0]  or baseit(a-a%b,b*base)+numerals[a%b%(base-1) or (a%b) and (base-1)]
    return baseit()

explanation

In any base every number is equal to a1+a2*base**2+a3*base**3... The "mission" is to find all a 's.

For everyN=1,2,3... the code is isolating the aN*base**N by "mouduling" by b for b=base**(N+1) which slice all a 's bigger than N, and slicing all the a 's that their serial is smaller than N by decreasing a everytime the func is called by the current aN*base**N .

Base%(base-1)==1 therefor base**p%(base-1)==1 and therefor q*base^p%(base-1)==q with only one exception when q=base-1 which returns 0. To fix that in case it returns 0 the func is checking is it 0 from the beggining.

advantages

in this sample theres only one multiplications (instead of division) and some moudulueses which relatively takes small amounts of time.

It actually depends on what is being used to print the result. Usually, the result is the same, just as you say -

Historically carriage return is supposed to do about what the home button does: return the caret to the start of the line.

\n is supposed to give you a new line but not move the caret.

If you think about old printers, you're pretty much thinking how the original authors of the character sets were thinking. It's a different operation moving the paper feeder and moving the caret. These two characters express that difference.

Try to list all files' names in the directory by calling:

File file = new File(".");
for(String fileNames : file.list()) System.out.println(fileNames);

and see if you will find your files in the list.

You can use EditText.setText(...) to set the current text of an EditText field.

Example:

yourEditText.setText(currentUserName);

The answer below is apparently obsolete now, but works with older drivers. See comments.

If you have the connection string you could also use MongoDatabase directly:

var db =  MongoDatabase.Create(connectionString);
var coll = db.GetCollection("MyCollection");

Both worked for me.

SELECT * FROM TABLE(SYSPROC.ENV_GET_INST_INFO());

or

SELECT * FROM SYSIBMADM.ENV_INST_INFO;

You can use this function to query for any element on the page, regardless of if it is nested inside of an iframe (or many iframes):

function querySelectorAllInIframes(selector) {
  let elements = [];

  const recurse = (contentWindow = window) => {

    const iframes = contentWindow.document.body.querySelectorAll('iframe');
    iframes.forEach(iframe => recurse(iframe.contentWindow));
    
    elements = elements.concat(contentWindow.document.body.querySelectorAll(selector));
  }

  recurse();

  return elements;
};

querySelectorAllInIframes('#elementToBeFound');

Note: Keep in mind that each of the iframes on the page will need to be of the same-origin, or this function will throw an error.

The numpy and scipy libraries include the composite trapezoidal (numpy.trapz) and Simpson's (scipy.integrate.simps) rules.

Here's a simple example. In both trapz and simps, the argument dx=5 indicates that the spacing of the data along the x axis is 5 units.

from __future__ import print_function

import numpy as np
from scipy.integrate import simps
from numpy import trapz


# The y values.  A numpy array is used here,
# but a python list could also be used.
y = np.array([5, 20, 4, 18, 19, 18, 7, 4])

# Compute the area using the composite trapezoidal rule.
area = trapz(y, dx=5)
print("area =", area)

# Compute the area using the composite Simpson's rule.
area = simps(y, dx=5)
print("area =", area)

Output:

area = 452.5
area = 460.0

When using NOT IN, you should also consider NOT EXISTS, which handles the null cases silently. See also PostgreSQL Wiki

SELECT mac, creation_date 
FROM logs lo
WHERE logs_type_id=11
AND NOT EXISTS (
  SELECT *
  FROM consols nx
  WHERE nx.mac = lo.mac
  );

Ljava.lang.String;@ is returned where you used string arrays as strings. Employee.getSelectCancel() does not seem to return a String[]

It is purely a string:

startInfo.Arguments = "-sk server -sky exchange -pe -n CN=localhost -ir LocalMachine -is Root -ic MyCA.cer -sr LocalMachine -ss My MyAdHocTestCert.cer"

Of course, when arguments contain whitespaces you'll have to escape them using \" \", like:

"... -ss \"My MyAdHocTestCert.cer\""

See MSDN for this.

Use:

std::map<std::string, std::string>::const_iterator

instead:

std::map<std::string, std::string>::iterator

All you need to do is make an array of fields and then set it to the class you want like shown below.

Field fld[] = (class name).class.getDeclaredFields();   
for(Field x : fld)
{System.out.println(x);}

For example if you did

Field fld[] = Integer.class.getDeclaredFields();
          for(Field x : fld)
          {System.out.println(x);}

you would get

public static final int java.lang.Integer.MIN_VALUE
public static final int java.lang.Integer.MAX_VALUE
public static final java.lang.Class java.lang.Integer.TYPE
static final char[] java.lang.Integer.digits
static final char[] java.lang.Integer.DigitTens
static final char[] java.lang.Integer.DigitOnes
static final int[] java.lang.Integer.sizeTable
private static java.lang.String java.lang.Integer.integerCacheHighPropValue
private final int java.lang.Integer.value
public static final int java.lang.Integer.SIZE
private static final long java.lang.Integer.serialVersionUID

There is another way to pass parameters to a controller by injecting $routeParams into your controller and then using url parameters described here What's the most concise way to read query parameters in AngularJS?

Check your Pattern (DD-MMM-YYYY) and the input for the parse("29-11-2018") method. Input to the parse method should follow : DD-MMM-YYYY i,e. 21-AUG-2019

In My Code:

String pattern = "DD-MMM-YYYY";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(pattern);

    try {
        startDate = simpleDateFormat.parse("29-11-2018");// here no pattern match 
        endDate = simpleDateFormat.parse("28-AUG-2019");// Ok 
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

java.lang.Integer is not a super class of BigInteger. Both BigInteger and Integer do inherit from java.lang.Number, so you could cast to a java.lang.Number.

See the java docs http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Number.html

Try this:

...JOIN sys.allocation_units a ON 
  (a.type=2 AND a.container_id = p.partition_id)
  OR (a.type IN (1, 3) AND a.container_id = p.hobt_id)

Just adding in for JupyterLab users. Ctrl, (advanced settings) and pasting the below in User References under keyboard shortcuts does the trick for me.

There's some proposition over the web (and this page) to use ViewConfiguration.getScaledTouchSlop() to have a device-scaled value for SWIPE_MIN_DISTANCE.

getScaledTouchSlop() is intended for the "scrolling threshold" distance, not swipe. The scrolling threshold distance has to be smaller than a "swing between page" threshold distance. For example, this function returns 12 pixels on my Samsung GS2, and the examples quoted in this page are around 100 pixels.

With API Level 8 (Android 2.2, Froyo), you've got getScaledPagingTouchSlop(), intended for page swipe. On my device, it returns 24 (pixels). So if you're on API Level < 8, I think "2 * getScaledTouchSlop()" should be the "standard" swipe threshold. But users of my application with small screens told me that it was too few... As on my application, you can scroll vertically, and change page horizontally. With the proposed value, they sometimes change page instead of scrolling.

if you are using es6 this should work:

<input {...{ "customattribute": "somevalue" }} />

Expanding on @gecco 's answer, the following is an example that'll show you the difference:

def foo(**kwargs):
    for entry in kwargs.items():
        print("Key: {}, value: {}".format(entry[0], entry[1]))

# call using normal keys:
foo(a=1, b=2, c=3)
# call using an unpacked dictionary:
foo(**{"a": 1, "b":2, "c":3})

# call using a dictionary fails because the function will think you are
# giving it a positional argument
foo({"a": 1, "b": 2, "c": 3})
# this yields the same error as any other positional argument
foo(3)
foo("string")

Here you can see how unpacking a dictionary works, and why sending an actual dictionary fails

You could also use the below code to redirect to the main page (home):

{ path: '', redirectTo: 'home', pathMatch: 'full'}

After specifying your redirect as above, you can redirect the other pages, for example:

{ path: 'add-new-registration', component: AddNewRegistrationComponent},
{ path: 'view-registration', component: ViewRegistrationComponent},
{ path: 'home', component: HomeComponent}

For me error occurred with this setup:

AndroidAnnotations Spring Android RestTemplate Module and ...

GsonHttpMessageConverter

Android annotations has some problems with this converted to generate POST request without parameter. Simply parameter new Object() solved it for me.

You must have some virtual function declared in one of the parent classes and never implemented in any of the child classes. Make sure that all virtual functions are implemented somewhere in the inheritence chain. If a class's definition includes a pure virtual function that is never implemented, an instance of that class cannot ever be constructed.

If you're not too worried in accuracy after days, you can simply do the maths

function timeSince(when) { // this ignores months
    var obj = {};
    obj._milliseconds = (new Date()).valueOf() - when.valueOf();
    obj.milliseconds = obj._milliseconds % 1000;
    obj._seconds = (obj._milliseconds - obj.milliseconds) / 1000;
    obj.seconds = obj._seconds % 60;
    obj._minutes = (obj._seconds - obj.seconds) / 60;
    obj.minutes = obj._minutes % 60;
    obj._hours = (obj._minutes - obj.minutes) / 60;
    obj.hours = obj._hours % 24;
    obj._days = (obj._hours - obj.hours) / 24;
    obj.days = obj._days % 365;
    // finally
    obj.years = (obj._days - obj.days) / 365;
    return obj;
}

then timeSince(pastDate); and use the properties as you like.

Otherwise you can use .getUTC* to calculate it, but note it may be slightly slower to calculate

function timeSince(then) {
    var now = new Date(), obj = {};
    obj.milliseconds = now.getUTCMilliseconds() - then.getUTCMilliseconds();
    obj.seconds = now.getUTCSeconds() - then.getUTCSeconds();
    obj.minutes = now.getUTCMinutes() - then.getUTCMinutes();
    obj.hours = now.getUTCHours() - then.getUTCHours();
    obj.days = now.getUTCDate() - then.getUTCDate();
    obj.months = now.getUTCMonth() - then.getUTCMonth();
    obj.years = now.getUTCFullYear() - then.getUTCFullYear();
    // fix negatives
    if (obj.milliseconds < 0) --obj.seconds, obj.milliseconds = (obj.milliseconds + 1000) % 1000;
    if (obj.seconds < 0) --obj.minutes, obj.seconds = (obj.seconds + 60) % 60;
    if (obj.minutes < 0) --obj.hours, obj.minutes = (obj.minutes + 60) % 60;
    if (obj.hours < 0) --obj.days, obj.hours = (obj.hours + 24) % 24;
    if (obj.days < 0) { // months have different lengths
        --obj.months;
        now.setUTCMonth(now.getUTCMonth() + 1);
        now.setUTCDate(0);
        obj.days = (obj.days + now.getUTCDate()) % now.getUTCDate();
    }
    if (obj.months < 0)  --obj.years, obj.months = (obj.months + 12) % 12;
    return obj;
}

I use HAVING for constraining a query based on the results of an aggregate function. E.G. select * in blahblahblah group by SOMETHING having count(SOMETHING)>0

Try this code:

import java.util.Scanner;

public class BasicElement {
    public static void main(String[] args){
        Scanner input = new Scanner(System.in);
        int hours;
        System.out.print("Enter the hours to convert:");
        hours =input.nextInt();
        int d=hours/24;
        int m=hours%24;
        System.out.println(d+"days"+" "+m+"hours");     

    }
}

You can try using a simple library like

After installing via gradle and adding permissions initiate SmsVerifyCatcher in method like onCreate activity:

    smsVerifyCatcher = new SmsVerifyCatcher(this, new OnSmsCatchListener<String>() {
    @Override
    public void onSmsCatch(String message) {
        String code = parseCode(message);//Parse verification code
        etCode.setText(code);//set code in edit text
        //then you can send verification code to server
    }
});

Also, override activity lifecicle methods:

  @Override
protected void onStart() {
    super.onStart();
    smsVerifyCatcher.onStart();
}

@Override
protected void onStop() {
    super.onStop();
    smsVerifyCatcher.onStop();
}

/**
 * need for Android 6 real time permissions
 */
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    smsVerifyCatcher.onRequestPermissionsResult(requestCode, permissions, grantResults);
}


public String parseCode(String message) {
    Pattern p = Pattern.compile("\\b\\d{4}\\b");
    Matcher m = p.matcher(message);
    String code = "";
    while (m.find()) {
        code = m.group(0);
    }
    return code;
}

I had the same problem even when I created a fresh project. I was creating the Java project within Eclipse, then mavenize it, then going into java build path properties removing src/ and adding src/main/java and src/test/java. When I run Maven update it used to give nested path error.
Then I finally realized -because I had not seen that entry before- there is a <sourceDirectory>src</sourceDirectory> line in pom file written when I mavenize it. It was resolved after removing it.

When it says that, just open the shell and do git status. That will give you a decent idea of what could be wrong and the state of your repo.

I can't give you a specific error for this as it happens for many reasons in Github for Windows, like say some problem in updating submodules etc.

into Chrome, right click -> Inspect Element. Go to the tab active tracking of resources and if you have not already. Now the left hand sidebar thingy down until you see "Cookies", click below your domain name and to remove a cookie just right-click on it and "Delete"

From the Maven docs, sounds like it's just a difference in which repository you install the package into:

• install - install the package into the local repository, for use as a dependency in other projects locally
• deploy - done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.

Maybe there is some confusion in that "install" to the CI server installs it to it's local repository, which then you as a user are sharing?

Think about it as array of array.

If you do this str[x][y], then there is array of length x where each element in turn contains array of length y. In java its not necessary for second dimension to have same length. So for x=i you can have y=m and x=j you can have y=n

For this your declaration looks like

String[][] test = new String[4][]; test[0] = new String[3]; test[1] = new String[2];

etc..

If you intend to use this output in production, then use the Trace class members. This makes the code portable, you can wire up different types of listeners and output to the console window, debug window, log file, or whatever else you like.

If this is just some temporary debugging code that you're using to verify that certain code is being executed or has the correct values, then use the Debug class as Zach suggests.

If you absolutely must use the console, then you can attach a console in the program's Main method.

use some thing like

import java.io.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;

//method to convert Document to String
public String getStringFromDocument(Document doc)
{
    try
    {
       DOMSource domSource = new DOMSource(doc);
       StringWriter writer = new StringWriter();
       StreamResult result = new StreamResult(writer);
       TransformerFactory tf = TransformerFactory.newInstance();
       Transformer transformer = tf.newTransformer();
       transformer.transform(domSource, result);
       return writer.toString();
    }
    catch(TransformerException ex)
    {
       ex.printStackTrace();
       return null;
    }
} 

Following the suggestion by JiminP....

I made a jsFiddle that will "smoothly" transition between two spans in case anyone is interested in seeing this in action. You have two main options:

1. one span fades out at the same time as the other span is fading in
2. one span fades out followed by the other span fading in.

The first time you click the button, number 1 above will occur. The second time you click the button, number 2 will occur. (I did this so you can visually compare the two effects.)

Try it Out: http://jsfiddle.net/jWcLz/594/

Details:

Number 1 above (the more difficult effect) is accomplished by positioning the spans directly on top of each other via CSS with absolute positioning. Also, the jQuery animates are not chained together, so that they can execute at the same time.

HTML

<div class="onTopOfEachOther">
    <span id='a'>Hello</span>
    <span id='b' style="display: none;">Goodbye</span>
</div>

<br />
<br />

<input type="button" id="btnTest" value="Run Test" />

CSS

.onTopOfEachOther {
    position: relative;
}
.onTopOfEachOther span {
    position: absolute;
    top: 0px;
    left: 0px;
}

JavaScript

$('#btnTest').click(function() {        
    fadeSwitchElements('a', 'b');    
}); 

function fadeSwitchElements(id1, id2)
{
    var element1 = $('#' + id1);
    var element2 = $('#' + id2);

    if(element1.is(':visible'))
    {
        element1.fadeToggle(500);
        element2.fadeToggle(500);
    }
    else
    {
         element2.fadeToggle(500, function() {
            element1.fadeToggle(500);
        });   
    }    
}

To clear the history, simply do:

this.appView.clearHistory();

You are going to need to call the SmsManager class. You are probably going to need to use the STATUS_ON_ICC_READ constant and maybe put what you get there into your apps local db so that you can keep track of what you have already read vs the new stuff for your app to parse through. BUT bear in mind that you have to declare the use of the class in your manifest, so users will see that you have access to their SMS called out in the permissions dialogue they get when they install. Seeing SMS access is unusual and could put some users off. Good luck.

Here is the link that goes into depth on the Sms Manager

you can easily use

document.documentElement.clientWidth

Please Note: The following answer only applied to WPF under the 3.5 Framework as NET 4.0 runtime has it's own datetime control.

By default WPF 3.5 does not come with a date time picker like winforms.

However a date picker has been added in the WPF tool kit produced by Microsoft which can be downloaded here. I guess it will become part of the framework in a future release.

It is simple to add a reference to the WPFToolkit.dll, see it in the tool box and distribute with your application by following the instructions on the website.

Before this was available other people had created 3rd party pickers (which you may prefer) or alternatively used the less ideal solution of using the winforms control in a WPF application.

Update: This so question is very similar this one which also has a link to a walk through for the datepicker along with other links.

Although this thread dates back to 2014, the issue can still be current to many of us. Here is how I dealt with it in a jQuery 1.12 /PHP 5.6 context:

• jQuery sent its XHR request using only limited headers; only 'Origin' was sent.
• No preflight request was needed.
• The server only had to detect such a request, and add the "Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN'] header, after detecting that this was a cross-origin XHR.

PHP Code sample:

if (!empty($_SERVER['HTTP_ORIGIN'])) {
    // Uh oh, this XHR comes from outer space...
    // Use this opportunity to filter out referers that shouldn't be allowed to see this request
    if (!preg_match('@\.partner\.domain\.net$@'))
        die("End of the road if you're not my business partner.");

    // otherwise oblige
    header("Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN']);
}
else {
    // local request, no need to send a specific header for CORS
}

In particular, don't add an exit; as no preflight is needed.

Given an array you can use the Array.ConvertAll method:

int[] myInts = Array.ConvertAll(arr, s => int.Parse(s));

Thanks to Marc Gravell for pointing out that the lambda can be omitted, yielding a shorter version shown below:

int[] myInts = Array.ConvertAll(arr, int.Parse);

A LINQ solution is similar, except you would need the extra ToArray call to get an array:

int[] myInts = arr.Select(int.Parse).ToArray();

I had this issues and solved if by adding a symlink to mysql_config.

I had installed mysql with homebrew and saw this in the output.

Error: The `brew link` step did not complete successfully

Depending on how you got mysql it will be in different places. In my case /usr/local/Cellar/mysql
Once you know where it is you should be able to ma a symbolic link to where python is looking for it. /usr/local/mysql

This worked for me.

ln -s /usr/local/Cellar/mysql/<< VERSION >>/bin/mysql_config   /usr/local/mysql/bin/mysql_config

Yes, simply set it to another value:

$_POST['text'] = 'another value';

This will override the previous value corresponding to text key of the array. The $_POST is superglobal associative array and you can change the values like a normal PHP array.

Caution: This change is only visible within the same PHP execution scope. Once the execution is complete and the page has loaded, the $_POST array is cleared. A new form submission will generate a new $_POST array.

If you want to persist the value across form submissions, you will need to put it in the form as an input tag's value attribute or retrieve it from a data store.

You can use {} arround your variable, to separate it from what's after:

echo "{$test}y"

As reference, you can take a look to the Variable parsing - Complex (curly) syntax section of the PHP manual.

The .NET framework actually provides an interface that you can use for notifying subscribers when a property has changed: System.ComponentModel.INotifyPropertyChanged. This interface has one event PropertyChanged. Its usually used in WPF for binding but I have found it useful in business layers as a way to standardize property change notification.

In terms of thread safety I would put a lock under in the setter so that you don't run into any race conditions.

Here are my thoughts in code :) :

public class MyClass : INotifyPropertyChanged
{
    private object _lock;

    public int MyProperty
    {
        get
        {
            return _myProperty;
        }
        set
        {
            lock(_lock)
            {
                //The property changed event will get fired whenever
                //the value changes. The subscriber will do work if the value is
                //1. This way you can keep your business logic outside of the setter
                if(value != _myProperty)
                {
                    _myProperty = value;
                    NotifyPropertyChanged("MyProperty");
                }
            }
        }
    }

    private NotifyPropertyChanged(string propertyName)
    {
        //Raise PropertyChanged event
    }
    public event PropertyChangedEventHandler PropertyChanged;
}


public class MySubscriber
{
    private MyClass _myClass;        

    void PropertyChangedInMyClass(object sender, PropertyChangedEventArgs e)
    {
        switch(e.PropertyName)
        {
            case "MyProperty":
                DoWorkOnMyProperty(_myClass.MyProperty);
                break;
        }
    }

    void DoWorkOnMyProperty(int newValue)
    {
        if(newValue == 1)
        {
             //DO WORK HERE
        }
    }
}

Hope this is helpful :)

Why don't you just stash the vbscript in a batch/vbscript file hybrid. Name the batch hybrid Converter.bat and you can execute it directly as Converter from the cmd line. Sure you can default ALL scripts to run from Cscript or Wscript, but if you want to execute your vbs as a windows script rather than a console script, this could cause some confusion later on. So just set your code to a batch file and run it directly.

Check the answer -> Here

And here is an example:

Converter.bat

::' VBS/Batch Hybrid
::' --- Batch portion ---------
rem^ &@echo off
rem^ &call :'sub
rem^ &exit /b

:'sub
rem^ &echo begin batch
rem^ &cscript //nologo //e:vbscript "%~f0"
rem^ &echo end batch
rem^ &exit /b

'----- VBS portion -----
Dim tester
tester = "Convert data here"
Msgbox tester

For your purpose, this simple class should be all you need:

class Timer {
    private $time = null;
    public function __construct() {
        $this->time = time();
        echo 'Working - please wait..<br/>';
    }

    public function __destruct() {
        echo '<br/>Job finished in '.(time()-$this->time).' seconds.';
    }
}


$t = new Timer(); // echoes "Working, please wait.."

[some operations]

unset($t);  // echoes "Job finished in n seconds." n = seconds elapsed

you can check ZBarSDK to reads QR Code and ECN/ISBN codes it's simple to integrate try the following code.

- (void)scanBarcodeWithZBarScanner
  {
// ADD: present a barcode reader that scans from the camera feed
ZBarReaderViewController *reader = [ZBarReaderViewController new];
reader.readerDelegate = self;
reader.supportedOrientationsMask = ZBarOrientationMaskAll;

ZBarImageScanner *scanner = reader.scanner;
// TODO: (optional) additional reader configuration here

// EXAMPLE: disable rarely used I2/5 to improve performance
 [scanner setSymbology: ZBAR_I25
               config: ZBAR_CFG_ENABLE
                   to: 0];

//Get the return value from controller
[reader setReturnBlock:^(BOOL value) {

}

and in didFinishPickingMediaWithInfo we get bar code value.

    - (void) imagePickerController: (UIImagePickerController*) reader
   didFinishPickingMediaWithInfo: (NSDictionary*) info
   {
    // ADD: get the decode results
    id<NSFastEnumeration> results =
    [info objectForKey: ZBarReaderControllerResults];
    ZBarSymbol *symbol = nil;
    for(symbol in results)
    // EXAMPLE: just grab the first barcode
    break;

    // EXAMPLE: do something useful with the barcode data
    barcodeValue = symbol.data;

    // EXAMPLE: do something useful with the barcode image
    barcodeImage =   [info objectForKey:UIImagePickerControllerOriginalImage];
    [_barcodeIV setImage:barcodeImage];

    //set the values for to TextFields
    [self setBarcodeValue:YES];

    // ADD: dismiss the controller (NB dismiss from the *reader*!)
    [reader dismissViewControllerAnimated:YES completion:nil];
   }

I had a similar kind of issue, but with some differences...

In my case, my main form has a Control (vendor) which value I used to update a Query in my DB, using the following code:

Sub Set_Qry_PedidosRealizadosImportados_frm(Vd As Long)
Dim temp_qry As DAO.QueryDef

'Procedimento para ajustar o codigo do cliente na Qry_Pedidos realizados e importados
'Procedure to adjust the code of the client on Qry_Pedidos realizados e importados
Set temp_qry = CurrentDb.QueryDefs("Qry_Pedidos realizados e importados")
temp_qry.SQL = "SELECT DISTINCT " & _
            "[Qry_Pedidos distintos].[Codigo], " & _
            "[Qry_Pedidos distintos].[Razao social], " & _
            "COUNT([Qry_Pedidos distintos].[Pedido Avante]) As [Pedidos realizados], " & _
            "SUM(IIf(NZ([Qry_Pedidos distintos].[Pedido Flexx], 0) > 1, 1, 0)) As [Pedidos Importados] " & _
            "FROM [Qry_Pedidos distintos] " & _
            "WHERE [Qry_Pedidos distintos].Vd = " & Vd & _
            " Group BY " & _
            "[Qry_Pedidos distintos].[Razao social], " & _
            "[Qry_Pedidos distintos].[Codigo];"
End Sub

Since the beginning my subform record source was the query named "Qry_Pedidos realizados e importados".

But the only way I could update the subform data inside the main form context was to refresh the data source of the subform to it self, like posted bellow:

Private Sub cmb_vendedor_v1_Exit(Cancel As Integer)
'Codigo para atualizar o comando SQL da query
'Code to update the SQL statement of the query 
    Call Set_Qry_Pedidosrealizadosimportados_frm(Me.cmb_vendedor_v1.Value)

'Codigo para forçar o Access a aceitar o novo comando SQL
'Code to force de Access to accept the new sql statement
    Me!Frm_Pedidos_realizados_importados.Form.RecordSource = "Qry_Pedidos realizados e importados"
End Sub

No refresh, recalc, requery, etc, was necessary after all...

In my case, I had to do the following while running with Junit5

@SpringBootTest(classes = {abc.class}) @ExtendWith(SpringExtension.class

Here abc.class was the class that was being tested

Instead of overwriting the html every time, just toggle the class.

$('#click_advance').click(function() {
    $('#display_advance').toggle('1000');
    $("i", this).toggleClass("icon-circle-arrow-up icon-circle-arrow-down");
});

A very simple, non-technical rule-of-thumb would be that clustered indexes are usually used for your primary key (or, at least, a unique column) and that non-clustered are used for other situations (maybe a foreign key). Indeed, SQL Server will by default create a clustered index on your primary key column(s). As you will have learnt, the clustered index relates to the way data is physically sorted on disk, which means it's a good all-round choice for most situations.

Exporting without default means it's a "named export". You can have multiple named exports in a single file. So if you do this,

class Template {}
class AnotherTemplate {}

export { Template, AnotherTemplate }

then you have to import these exports using their exact names. So to use these components in another file you'd have to do,

import {Template, AnotherTemplate} from './components/templates'

Alternatively if you export as the default export like this,

export default class Template {}

Then in another file you import the default export without using the {}, like this,

import Template from './components/templates'

There can only be one default export per file. In React it's a convention to export one component from a file, and to export it is as the default export.

You're free to rename the default export as you import it,

import TheTemplate from './components/templates'

And you can import default and named exports at the same time,

import Template,{AnotherTemplate} from './components/templates'

You can use any of the following:

\b      #A word break and will work for both spaces and end of lines.
(^|\s)  #the | means or. () is a capturing group. 


/\b(stackoverflow)\b/

Also, if you don't want to include the space in your match, you can use lookbehind/aheads.

(?<=\s|^)         #to look behind the match
(stackoverflow)   #the string you want. () optional
(?=\s|$)          #to look ahead.

The collection view has a layout object. In your case, it is probably a flow layout (UICollectionViewFlowLayout). Set the flow layout's itemSize property.

Simply use the delegate approach.

int val;
Thread thread = new Thread(() => { val = Multiply(1, 2); });
thread.Start();

Now make Multiply function that will work on another thread:

int Multiply(int x, int y)
{
    return x * y;
}

Hi please check the below link

https://www.postgresql.org/docs/current/xfunc-sql.html

EX:

CREATE FUNCTION sum_n_product_with_tab (x int)
RETURNS TABLE(sum int, product int) AS $$
    SELECT $1 + tab.y, $1 * tab.y FROM tab;
$$ LANGUAGE SQL;

I think the pattern priestc mentions is more likely to be the usual cause of this issue when using PostgreSQL.

However I feel there are valid uses for the pattern and I don't think this issue should be a reason to always avoid it. For example:

try:
    profile = user.get_profile()
except ObjectDoesNotExist:
    profile = make_default_profile_for_user(user)

do_something_with_profile(profile)

If you do feel OK with this pattern, but want to avoid explicit transaction handling code all over the place then you might want to look into turning on autocommit mode (PostgreSQL 8.2+): https://docs.djangoproject.com/en/dev/ref/databases/#autocommit-mode

DATABASES['default'] = {
    #.. you usual options...
    'OPTIONS': {
        'autocommit': True,
    }
}

I am unsure if there are important performance considerations (or of any other type).

In the left list, right click on "AppIcon" and click on "Open in finder" A folder with name "AppIcon.appiconset" will open. Paste all the graphics with required resolution there. Once done, all those images will be visible in this same screen(one in your screen shot). then drag them to appropriate box. App icons have been added. Same process for Launch images. Launch images through this process are added for iOS 7 and below. For iOS 8 separate LaunchScreen.xib file is made by default.

Well, you pretty much gave yourself the answer. In your CSS give the containing element a min-width. If you have to support IE6 you can use the min-width-trick:

#container {
    min-width:800px;
    width: auto !important;
    width:800px;
}

That will effectively give you 800px min-width in IE6 and any up-to-date browsers.

Go to [Tools, Options], section "Web Forms Designer" and enable the option "Enable Web Forms Designer". That should give you the Design and Split option again.

In my case for exact same error, I was also not the only developer.

So I went to commit & push my changes at same time, seen at bottom of the Commit dialog popup:

...but I made the huge mistake of forgetting to hit the Fetch button to see if I have latest, which I did not.

The commit successfully executed, however not the push, but instead gives the same mentioned error; ...even though other developers didn't alter same files as me, I cannot pull latest as same error is presented.

The GUI Solution

Most of the time I prefer sticking with Sourcetree's GUI (Graphical User Interface). This solution might not be ideal, however this is what got things going again for me without worrying that I may lose my changes or compromise more recent updates from other developers.

STEP 1

Right-click on the commit right before yours to undo your locally committed changes and select Reset current branch to this commit like so:

STEP 2

Once all the loading spinners disappear and Sourcetree is done loading the previous commit, at the top-left of window, click on Pull button...

...then a dialog popup will appear, and click the OK button at bottom-right:

STEP 3

After pulling latest, if you do not get any errors, skip to STEP 4 (next step below). Otherwise if you discover any merge conflicts at this point, like I did with my Web.config file:

...then click on the Stash button at the top, a dialog popup will appear and you will need to write a Descriptive-name-of-your-changes, then click the OK button:

...once Sourcetree is done stashing your altered file(s), repeat actions in STEP 2 (previous step above), and then your local files will have latest changes. Now your changes can be reapplied by opening your STASHES seen at bottom of Sourcetree left column, use the arrow to expand your stashes, then right-click to choose Apply Stash 'Descriptive-name-of-your-changes', and after select OK button in dialog popup that appears:

IF you have any Merge Conflict(s) right now, go to your preferred text-editor, like Visual Studio Code, and in the affected files select the Accept Incoming Change link, then save:

Then back to Sourcetree, click on the Commit button at top:

then right-click on the conflicted file(s), and under Resolve Conflicts select the Mark Resolved option:

STEP 4

Finally!!! We are now able to commit our file(s), also checkmark the Push changes immediately to origin option before clicking the Commit button:

P.S. while writing this, a commit was submitted by another developer right before I got to commit, so had to pretty much repeat steps.

Try renaming the default file. In my case, a recent move to IIS7.5 gave the 405 error. I changed index.aspx to default.aspx and it worked immediately for me.

Use strncpy

e.g.

strncpy(dest, src + beginIndex, endIndex - beginIndex);

This assumes you've

1. Validated that dest is large enough.
2. endIndex is greater than beginIndex
3. beginIndex is less than strlen(src)
4. endIndex is less than strlen(src)

var obj = {name: 'Krishna', gender: 'male'};
angular.forEach(obj, function(value, key) {
    console.log(key + ': ' + value);
});

yields the attributes of obj with their respective values:

name: Krishna
gender: male

ConcurrentHashMap allows concurrent access to data. Whole map is divided into segments.

Read operation ie. get(Object key) is not synchronized even at segment level.

But write operations ie. remove(Object key), get(Object key) acquire lock at segment level. Only part of whole map is locked, other threads still can read values from various segments except locked one.

SynchronizedMap on the other hand, acquire lock at object level. All threads should wait for current thread irrespective of operation(Read/Write).

inline if:

(('hypothesis') ? 'truthy conclusion' : 'falsey conclusion')

truthy conclusion: statements executed when hypothesis is true

falsey conclusion: statements executed when hypothesis is false

your example:

var c = ((a < b) ? 'a<b statements' : '!(a<b) statements');

string texts[] = {"Apple", "Banana", "Orange"};
for( unsigned int a = 0; a < sizeof(texts); a = a + 1 )
{
    cout << "value of a: " << texts[a] << endl;
}

Nope. Totally a wrong way of iterating through an array. sizeof(texts) is not equal to the number of elements in the array!

The modern, C++11 ways would be to:

• use std::array if you want an array whose size is known at compile-time; or
• use std::vector if its size depends on runtime

Then use range-for when iterating.

#include <iostream>
#include <array>


int main() {
    std::array<std::string, 3> texts = {"Apple", "Banana", "Orange"};
    // ^ An array of 3 elements with the type std::string

    for(const auto& text : texts) {   // Range-for!
        std::cout << text << std::endl;
    }
}

Live example

You may ask, how is std::array better than the ol' C array? The answer is that it has the additional safety and features of other standard library containers, mostly closely resembling std::vector. Further, The answer is that it doesn't have the quirks of decaying to pointers and thus losing type information, which, once you lose the original array type, you can't use range-for or std::begin/end on it.

Option a) Create a virtualenv, activate it and install:

virtualenv .venv
source .venv/bin/activate
pip install -r requirements.txt

Option b) Install in your homedir:

pip install --user -r requirements.txt

My recommendation use safe (a) option, so that requirements of this project do not interfere with other projects requirements.

Simply get the current item from pager and then ask your adapter to the fragment of that position.

 int currentItem = viewPager.getCurrentItem();
    Fragment item = mPagerAdapter.getItem(currentItem);
    if (null != item && item.isVisible()) {
       //do whatever want to do with fragment after doing type checking
        return;
    }

Use the new "on" event syntax.

$(document).ready(function() {
  $('form').on('submit', function(e){
    // validation code here
    if(!valid) {
      e.preventDefault();
    }
  });
});

Thanks for the responses. I think I've solved the problem just now.

Since LD_PRELOAD is for setting some library proloaded, I check the library that ld preloads with LD_PRELOAD, one of which is "liblunar-calendar-preload.so", that is not existing in the path "/usr/lib/liblunar-calendar-preload.so", but I find a similar library "liblunar-calendar-preload-2.0.so", which is a difference version of the former one.

Then I guess maybe liblunar-calendar-preload.so was updated to a 2.0 version when the system updated, leaving LD_PRELOAD remain to be "/usr/lib/liblunar-calendar-preload.so". Thus the preload library name was not updated to the newest version.

To avoid changing environment variable, I create a symbolic link under the path "/usr/lib"

sudo ln -s liblunar-calendar-preload-2.0.so liblunar-calendar-preload.so

Then I restart bash, the error is gone.

For understanding templates, it's of huge advantage to get the terminology straight because the way you speak about them determines the way to think about them.

Specifically, Area is not a template class, but a class template. That is, it is a template from which classes can be generated. Area<int> is such a class (it's not an object, but of course you can create an object from that class in the same ways you can create objects from any other class). Another such class would be Area<char>. Note that those are completely different classes, which have nothing in common except for the fact that they were generated from the same class template.

Since Area is not a class, you cannot derive the class Rectangle from it. You only can derive a class from another class (or several of them). Since Area<int> is a class, you could, for example, derive Rectangle from it:

class Rectangle:
  public Area<int>
{
  // ...
};

Since Area<int> and Area<char> are different classes, you can even derive from both at the same time (however when accessing members of them, you'll have to deal with ambiguities):

class Rectangle:
  public Area<int>,
  public Area<char>
{
  // ...
};

However you have to specify which classed to derive from when you define Rectangle. This is true no matter whether those classes are generated from a template or not. Two objects of the same class simply cannot have different inheritance hierarchies.

What you can do is to make Rectangle a template as well. If you write

template<typename T> class Rectangle:
  public Area<T>
{
  // ...
};

You have a template Rectangle from which you can get a class Rectangle<int> which derives from Area<int>, and a different class Rectangle<char> which derives from Area<char>.

It may be that you want to have a single type Rectangle so that you can pass all sorts of Rectangle to the same function (which itself doesn't need to know the Area type). Since the Rectangle<T> classes generated by instantiating the template Rectangle are formally independent of each other, it doesn't work that way. However you can make use of multiple inheritance here:

class Rectangle // not inheriting from any Area type
{
  // Area independent interface
};

template<typename T> class SpecificRectangle:
  public Rectangle,
  public Area<T>
{
  // Area dependent stuff
};

void foo(Rectangle&); // A function which works with generic rectangles

int main()
{
  SpecificRectangle<int> intrect;
  foo(intrect);

  SpecificRectangle<char> charrect;
  foo(charrect);
}

If it is important that your generic Rectangle is derived from a generic Area you can do the same trick with Area too:

class Area
{
  // generic Area interface
};

class Rectangle:
  public virtual Area // virtual because of "diamond inheritance"
{
  // generic rectangle interface
};

template<typename T> class SpecificArea:
  public virtual Area
{
  // specific implementation of Area for type T
};

template<typename T> class SpecificRectangle:
  public Rectangle, // maybe this should be virtual as well, in case the hierarchy is extended later
  public SpecificArea<T> // no virtual inheritance needed here
{
  // specific implementation of Rectangle for type T
};

umh.. like that?

firstElementChild might not be available in IE<9 (only firstChild)

on IE<9 firstChild is the firstElementChild because MS DOM (IE<9) is not storing empty text nodes. But if you do so on other browsers they will return empty text nodes...

my solution

child=(elem.firstElementChild||elem.firstChild)

this will give the firstchild even on IE<9

i think i am having a bit of confusion here. :) But seems no one else have ..

Are you asking which one to use in this scenario? If Yes then And is the correct answer.

If you are asking about how the operators are working, then

In php both AND, && and OR, || will work in the same way. If you are new in programming and php is one of your first languages them i suggest using AND and OR, because it increases readability and reduces confusion when you check back. But if you are familiar with any other languages already then you might already have familiarized the && and || operators.

I had PHP7.2 on a Ubuntu 16.04 server and it solved my problem:

sudo apt-get install zip unzip php-zip

Update

Tried this for Ubuntu 18.04 and worked as well.

You can use this code to convert a json file to csv file After reading the file, I am converting the object to pandas dataframe and then saving this to a CSV file

import os
import pandas as pd
import json
import numpy as np

data = []
os.chdir('D:\\Your_directory\\folder')
with open('file_name.json', encoding="utf8") as data_file:    
     for line in data_file:
        data.append(json.loads(line))

dataframe = pd.DataFrame(data)        
## Saving the dataframe to a csv file
dataframe.to_csv("filename.csv", encoding='utf-8',index= False)

Here is my method to do post request first pass in method map and data like

HashMap<String, String> param = new HashMap<String, String>();

param.put("Name", name);
param.put("Email", email);
param.put("Password", password);
param.put("Img_Name", "");

final JSONObject result = doPostRequest(map,Url);

public static JSONObject doPostRequest(HashMap<String, String> data, String url) {

    try {
        RequestBody requestBody;
        MultipartBuilder mBuilder = new MultipartBuilder().type(MultipartBuilder.FORM);

        if (data != null) {


            for (String key : data.keySet()) {
                String value = data.get(key);
                Utility.printLog("Key Values", key + "-----------------" + value);

                mBuilder.addFormDataPart(key, value);

            }
        } else {
            mBuilder.addFormDataPart("temp", "temp");
        }
        requestBody = mBuilder.build();


        Request request = new Request.Builder()
                .url(url)
                .post(requestBody)
                .build();

        OkHttpClient client = new OkHttpClient();
        Response response = client.newCall(request).execute();
        String responseBody = response.body().string();
        Utility.printLog("URL", url);
        Utility.printLog("Response", responseBody);
        return new JSONObject(responseBody);

    } catch (UnknownHostException | UnsupportedEncodingException e) {

        JSONObject jsonObject=new JSONObject();

        try {
            jsonObject.put("status","false");
            jsonObject.put("message",e.getLocalizedMessage());
        } catch (JSONException e1) {
            e1.printStackTrace();
        }
        Log.e(TAG, "Error: " + e.getLocalizedMessage());
    } catch (Exception e) {
        e.printStackTrace();
        JSONObject jsonObject=new JSONObject();

        try {
            jsonObject.put("status","false");
            jsonObject.put("message",e.getLocalizedMessage());
        } catch (JSONException e1) {
            e1.printStackTrace();
        }
        Log.e(TAG, "Other Error: " + e.getLocalizedMessage());
    }
    return null;
}

Diffrence between Foreach & map :

Map() : If you use map then map can return new array by iterating main array.

Foreach() : If you use Foreach then it can not return anything for each can iterating main array.

If you have multiply rows to delete and you don't want to alter the structure of your tables you can use cursor. 1-You first need to select rows to delete(in a cursor) 2-Then for each row in the cursor you delete the referencing rows and after that delete the row him self.

Ex:

--id is primary key of MainTable
    declare @id int
    set @id = 1
    declare theMain cursor for select FK from MainTable where MainID = @id
    declare @fk_Id int
    open theMain
    fetch next from theMain into @fk_Id
    while @@fetch_status=0
    begin
        --fkid is the foreign key 
        --Must delete from Main Table first then child.
        delete from MainTable where fkid = @fk_Id
        delete from ReferencingTable where fkid = @fk_Id
        fetch next from theMain into @fk_Id
    end
    close theMain
    deallocate theMain

Try to create a php.ini file in root and write the following command in and save it.

disable_functions =

Using this code will enable the phpinfo() function for you if it is disabled by the global PHP configuration.

If you are using the batch conversion, in the window click "options" in the "Batch conversion settings-output format" and tick the two boxes "save transparent color" (one under "PNG" and the other under "ICO").

Following on from brillout.com's answer, and also Roman Nurik's answer, and relaxing somewhat the the 'no SVG' requirement, you can desaturate images in Firefox using only a single SVG file and some CSS.

Your SVG file will look like this:

<?xml version="1.0" encoding="UTF-8"?>
<svg version="1.1"
     baseProfile="full"
     xmlns="http://www.w3.org/2000/svg">
    <filter id="desaturate">
        <feColorMatrix type="matrix" values="0.3333 0.3333 0.3333 0 0
                                             0.3333 0.3333 0.3333 0 0
                                             0.3333 0.3333 0.3333 0 0
                                             0      0      0      1 0"/>
    </filter>
</svg>

Save that as resources.svg, it can be reused from now on for any image you want to change to greyscale.

In your CSS you reference the filter using the Firefox specific filter property:

.target {
    filter: url(resources.svg#desaturate);
}

Add the MS proprietary ones too if you feel like it, apply that class to any image you want to convert to greyscale (works in Firefox >3.5, IE8).

edit: Here's a nice blog post which describes using the new CSS3 filter property in SalmanPK's answer in concert with the SVG approach described here. Using that approach you'd end up with something like:

img.desaturate{
    filter: gray; /* IE */
    -webkit-filter: grayscale(1); /* Old WebKit */
    -webkit-filter: grayscale(100%); /* New WebKit */
    filter: url(resources.svg#desaturate); /* older Firefox */
    filter: grayscale(100%); /* Current draft standard */
}

IIS automatically defined .ttf as application/octet-stream which seems to work fine and fontshop recommends .woff to be defined as application/octet-stream

No, this seems perfectly reasonable. There is a List<T>.AddRange() method that basically does just this, but requires your collection to be a concrete List<T>.

Configurations above didn't work for me. I tried a lot of combinations of keys, this one work fine:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>mydomain.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
    </dict>
</dict>

Both of these solutions are here in other forms. I found these a little more practical, clear, and useful:

Using dd:

BADLINESCOUNT=1
ORIGINALFILE=/tmp/whatever
dd if=${ORIGINALFILE} of=${ORIGINALFILE}.tmp status=none bs=1 count=$(printf "$(stat --format=%s ${ORIGINALFILE}) - $(tail -n${BADLINESCOUNT} ${ORIGINALFILE} | wc -c)\n" | bc )
/bin/mv -f ${ORIGINALFILE}.tmp ${ORIGINALFILE}

Using truncate:

BADLINESCOUNT=1
ORIGINALFILE=/tmp/whatever
truncate -s $(printf "$(stat --format=%s ${ORIGINALFILE}) - $(tail -n${BADLINESCOUNT} ${ORIGINALFILE} | wc -c)\n" | bc ) ${ORIGINALFILE}
