If you're working in a large multi-module project, with several different application.properties files, then try adding your value to the parent project's property file.

If you are unsure which is your parent project, check your project's pom.xml file, for a <parent> tag.

This solved the issue for me.

Change the file name if your file name is like pandas.py or pd.py, it will shadow the real name otherwise.

No functions, no cursors. Try this

with cte as(
select CHAR(65) chr, 65 i 
union all
select CHAR(i+1) chr, i=i+1 from cte
where CHAR(i) <'Z'
)
select * from(
SELECT id, Case when LEN(data)>len(REPLACE(data, chr,'')) then chr+chr end data 
FROM table1, cte) x
where Data is not null

Idiomatic solution that uses only a single groupby

(df.groupby(['col5', 'col2']).size() 
   .sort_values(ascending=False) 
   .reset_index(name='count') 
   .drop_duplicates(subset='col2'))

  col5 col2  count
0    3    A      3
1    1    D      3
2    5    B      2
6    3    C      1

Explanation

The result of the groupby size method is a Series with col5 and col2 in the index. From here, you can use another groupby method to find the maximum value of each value in col2 but it is not necessary to do. You can simply sort all the values descendingly and then keep only the rows with the first occurrence of col2 with the drop_duplicates method.

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.

data['result'] = data['result'].map(lambda x: x.lstrip('+-').rstrip('aAbBcC'))

You can also use:

map.setView(new L.LatLng(40.737, -73.923), 8);

It just depends on what behavior you want. map.panTo() will pan to the location with zoom/pan animation, while map.setView() immediately set the new view to the desired location/zoom level.

Try this:

import java.util.Scanner;

    /* Logic: Consider first character in the string and start counting occurrence of        
              this character in the entire string. Now add this character to a empty
              string "temp" to keep track of the already counted characters.
              Next start counting from next character and start counting the character        
              only if it is not present in the "temp" string( which means only if it is
              not counted already)
public class Counting_Occurences {

    public static void main(String[] args) {


        Scanner input=new Scanner(System.in);
        System.out.println("Enter String");
        String str=input.nextLine();

        int count=0;
        String temp=""; // An empty string to keep track of counted
                                    // characters


        for(int i=0;i<str.length();i++)
        {

            char c=str.charAt(i);  // take one character (c) in string

            for(int j=i;j<str.length();j++)
            {

                char k=str.charAt(j);  
    // take one character (c) and compare with each character (k) in the string
            // also check that character (c) is not already counted.
            // if condition passes then increment the count.
                if(c==k && temp.indexOf(c)==-1)                                                                          
                {

                    count=count+1;

                }

            }

             if(temp.indexOf(c)==-1)  // if it is not already counted
             {


            temp=temp+c; // append the character to the temp indicating
                                         // that you have already counted it.

System.out.println("Character   " + c + "   occurs   " + count + "    times");
             }  
            // reset the counter for next iteration 
              count=0;

        }


    }


}

Sometimes you want to change the capitalization of a lot of file names on a case insensitive filesystem (e.g. on OS X or Windows). Doing git mv commands will tire quickly. To make things a bit easier this is what I do:

1. Move all files outside of the directory to, let’s, say the desktop.
2. Do a git add . -A to remove all files.
3. Rename all files on the desktop to the proper capitalization.
4. Move all the files back to the original directory.
5. Do a git add .. Git should see that the files are renamed.

Now you can make a commit saying you have changed the file name capitalization.

You can achieve that by using positioning.

Try

position: absolute;

to get the 100% height.

str = "aaaaabbbb"
newstr = str[-4:]

See : http://codepad.org/S3zjnKoD

public String removeDuplicates(String dupCharsString){
    StringBuffer buffer = new StringBuffer(dupCharsString);
    int step = 0;
    while(step <= buffer.length()){
        for( int i = step + 1; i < buffer.length(); i++ ){
            if( buffer.charAt(i) == buffer.charAt(step) ){
                buffer.setCharAt(i, ' ');
            }
        }
        step++;
    }
    return buffer.toString().replaceAll("\\s","");
}

The difference between memcpy and memmove is that

1. in memmove, the source memory of specified size is copied into buffer and then moved to destination. So if the memory is overlapping, there are no side effects.

2. in case of memcpy(), there is no extra buffer taken for source memory. The copying is done directly on the memory so that when there is memory overlap, we get unexpected results.

These can be observed by the following code:

//include string.h, stdio.h, stdlib.h
int main(){
  char a[]="hare rama hare rama";

  char b[]="hare rama hare rama";

  memmove(a+5,a,20);
  puts(a);

  memcpy(b+5,b,20);
  puts(b);
}

Output is:

hare hare rama hare rama
hare hare hare hare hare hare rama hare rama

very easy with android

int i=10000;
byte b1=(byte)Color.alpha(i);
byte b2=(byte)Color.red(i);
byte b3=(byte)Color.green(i);
byte b4=(byte)Color.blue(i);

You could include the 'ncurses' library, and use getch() instead of getchar().

It would make for a handy function. Also, note I'm using STUFF instead of SUBSTRING.

create function str2uniq(@s varchar(50)) returns uniqueidentifier as begin
    -- just in case it came in with 0x prefix or dashes...
    set @s = replace(replace(@s,'0x',''),'-','')
    -- inject dashes in the right places
    set @s = stuff(stuff(stuff(stuff(@s,21,0,'-'),17,0,'-'),13,0,'-'),9,0,'-')
    return cast(@s as uniqueidentifier)
end

Use toCharArray() method. It splits the string into an array of characters:

http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html#toCharArray%28%29

String str = "aabbab";
char[] chs = str.toCharArray();

All you need is a reluctant quantifier:

regex: /aa.*?aa/

aabbabcaabda   => aabbabcaa

aaaaaabda      => aaaa

aabbabcaabda   => aabbabcaa

aababaaaabdaa  => aababaa, aabdaa

You could use negative lookahead, too, but in this case it's just a more verbose way accomplish the same thing. Also, it's a little trickier than gpojd made it out to be. The lookahead has to be applied at each position before the dot is allowed to consume the next character.

/aa(?:(?!aa).)*aa/

As for the approach suggested by Claudiu and finnw, it'll work okay when the sentinel string is only two characters long, but (as Claudiu acknowledged) it's too unwieldy for longer strings.

Here's an alternative approach using an interface to describe the shape of an options object to be passed via the pipe in the markup.

@Pipe({
  name: 'textContentTruncate'
})
export class TextContentTruncatePipe implements PipeTransform {

  transform(textContent: string, options: TextTruncateOptions): string {
    if (textContent.length >= options.sliceEnd) {
      let truncatedText = textContent.slice(options.sliceStart, options.sliceEnd);
      if (options.prepend) { truncatedText = `${options.prepend}${truncatedText}`; }
      if (options.append) { truncatedText = `${truncatedText}${options.append}`; }
      return truncatedText;
    }
    return textContent;
  }

}

interface TextTruncateOptions {
  sliceStart: number;
  sliceEnd: number;
  prepend?: string;
  append?: string;
}

Then in your markup:

{{someText | textContentTruncate:{sliceStart: 0, sliceEnd: 50, append: '...'} }}

This depends on implementation, but the general rule is that the domain is checked against all SANs and the common name. If the domain is found there, then the certificate is ok for connection.

RFC 5280, section 4.1.2.6 says "The subject name MAY be carried in the subject field and/or the subjectAltName extension". This means that the domain name must be checked against both SubjectAltName extension and Subject property (namely it's common name parameter) of the certificate. These two places complement each other, and not duplicate it. And SubjectAltName is a proper place to put additional names, such as www.domain.com or www2.domain.com

Update: as per RFC 6125, published in 2011, the validator must check SAN first, and if SAN exists, then CN should not be checked. Note that RFC 6125 is relatively recent and there still exist certificates and CAs that issue certificates, which include the "main" domain name in CN and alternative domain names in SAN. I.e. by excluding CN from validation if SAN is present, you can deny some otherwise valid certificate.

Something different:

wc -l `tree -if --noreport | grep -e'\.php$'`

This works out fine, but you need to have at least one *.php file in the current folder or one of its subfolders, or else wc stalls.

To find the version of the subversion REPOSITORY you can:

1. Look to the repository on the web and on the bottom of the page it will say something like:
   "Powered by Subversion version 1.5.2 (r32768)."
2. From the command line: <insert curl, grep oneliner here>

If not displayed, view source of the page

<svn version="1.6.13 (r1002816)" href="http://subversion.tigris.org/"> 

Now for the subversion CLIENT:

svn --version

will suffice

You could add the default rule with the alter table,

ALTER TABLE mytable ADD COLUMN created_at TIMESTAMP DEFAULT NOW()

then immediately set to null all the current existing rows:

UPDATE mytable SET created_at = NULL

Then from this point on the DEFAULT will take effect.

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Build your own

Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

.a files are created with the ar utility, and they are libraries. To use it with gcc, collect all .a files in a lib/ folder and then link with -L lib/ and -l<name of specific library>.

Collection of all .a files into lib/ is optional. Doing so makes for better looking directories with nice separation of code and libraries, IMHO.

This is also known as the "inline if", or as above the ternary operator. https://en.wikipedia.org/wiki/%3F:

It's used to reduce code, though it's not recommended to use a lot of these on a single line as it may make maintaining code quite difficult. Imagine:

a = b?c:(d?e:(f?g:h));

and you could go on a while.

It ends up basically the same as writing:

if(b)
  a = c;
else if(d)
  a = e;
else if(f)
  a = g;
else
  a = h;

In your case, "string requestUri = _apiURL + "?e=" + OperationURL[0] + ((OperationURL[1] == "GET") ? GetRequestSignature() : "");"

Can also be written as: (omitting the else, since it's an empty string)

string requestUri = _apiURL + "?e=" + OperationURL[0];
if((OperationURL[1] == "GET")
    requestUri = requestUri + GetRequestSignature();

or like this:

string requestUri;
if((OperationURL[1] == "GET")
    requestUri = _apiURL + "?e=" + OperationURL[0] + GetRequestSignature();
else
    requestUri = _apiURL + "?e=" + OperationURL[0];

Depending on your preference / the code style your boss tells you to use.

this one also gives the no.of lines in a file.

a=open('filename.txt','r')
l=a.read()
count=l.splitlines()
print(len(count))

You can't "add" values to an array as the array length is immutable. You can set values at specific array positions.

If you know how to do it with one-dimensional arrays then you know how to do it with n-dimensional arrays: There are no n-dimensional arrays in Java, only arrays of arrays (of arrays...).

But you can chain the index operator for array element access.

String[][] x = new String[2][];
x[0] = new String[1];
x[1] = new String[2];

x[0][0] = "a1";
    // No x[0][1] available
x[1][0] = "b1";
x[1][1] = "b2";

Note the dimensions of the child arrays don't need to match.

Since you are providing a relative pathway to the image, the image location is looked for from the location in which you have the css file. So if you have the image in a different location to the css file you could either try giving the absolute URL(pathway starting from the root folder) or give the relative file location path. In your case since img and css are in the folder assets to move from location of css file to the img file, you can use '..' operator to refer that the browser has to move 1 folder back and then follow the pathway you have after the '..' operator. This is basically how relative pathway works and you can use it to access resoures in different folders. Hope it helps.

Reason for the error:

Column expands to the maximum size in main axis direction (vertical axis), and so does the ListView.

Solutions

So, you need to constrain the height of the ListView. There are many ways of doing it, you can choose that best suits your need.

1. If you want to allow ListView to take up all remaining space inside Column use Expanded.

   Column(
     children: <Widget>[
       Expanded(
         child: ListView(...),
       )
     ],
   )
   

2. If you want to limit your ListView to certain height, you can use SizedBox.

   Column(
     children: <Widget>[
       SizedBox(
         height: 200, // constrain height
         child: ListView(),
       )
     ],
   )
   

3. If your ListView is small, you may try shrinkWrap property on it.

   Column(
     children: <Widget>[
       ListView(
         shrinkWrap: true, // use it
       )
     ],
   )
   

In Swift 3

import UIKit

let TEXTFIELD_BLUE  = UIColor.blue
let TEXTFIELD_GRAY  = UIColor.gray

class DBTextField: UITextField {
    /// Tetxfield Placeholder Color
    @IBInspectable var palceHolderColor: UIColor = TEXTFIELD_GRAY
    func setupTextField () {
        self.attributedPlaceholder = NSAttributedString(string:self.placeholder != nil ? self.placeholder! : "",
                                                            attributes:[NSForegroundColorAttributeName: palceHolderColor])
    }
}

class DBLocalizedTextField : UITextField {
    override func awakeFromNib() {
        super.awakeFromNib()
        self.placeholder = self.placeholder
    }
}

maybe this can help..

SELECT constraint_name, constraint_type, column_name
from user_constraints natural join user_cons_columns
where table_name = "my_table_name";

Use Enum's static method, GetNames. It returns a string[], like so:

Enum.GetNames(typeof(DataSourceTypes))

If you want to create a method that does only this for only one type of enum, and also converts that array to a List, you can write something like this:

public List<string> GetDataSourceTypes()
{
    return Enum.GetNames(typeof(DataSourceTypes)).ToList();
}

You will need Using System.Linq; at the top of your class to use .ToList()

With ES6 arrow functions it will be like this:

//Let's say we have these cars
let cars = [ { brand: 'Porsche', top_speed: 260 },
  { brand: 'Benz', top_speed: 110 },
  { brand: 'Fiat', top_speed: 90 },
  { brand: 'Aston Martin', top_speed: 70 } ]

Array.prototype.sort() can accept a comparator function (here I used arrow notation, but ordinary functions work the same):

let sortedByBrand = [...cars].sort((first, second) => first.brand > second.brand)

// [ { brand: 'Aston Martin', top_speed: 70 },
//   { brand: 'Benz', top_speed: 110 },
//   { brand: 'Fiat', top_speed: 90 },
//   { brand: 'Porsche', top_speed: 260 } ]

The above approach copies the contents of cars array into a new one and sorts it alphabetically based on brand names. Similarly, you can pass a different function:

let sortedBySpeed =[...cars].sort((first, second) => first.top_speed > second.top_speed)

//[ { brand: 'Aston Martin', top_speed: 70 },
//  { brand: 'Fiat', top_speed: 90 },
//  { brand: 'Benz', top_speed: 110 },
//  { brand: 'Porsche', top_speed: 260 } ]

If you don't mind mutating the orginal array cars.sort(comparatorFunction) will do the trick.

Powershell Solution:

If you're running windows, you can use PowerShell to remove multiple branches at once...

git branch -D ((git branch | Select-String -Pattern '^\s*3\.2\..*') | foreach{$_.ToString().Trim()})
//this will remove all branches starting with 3.2.

git branch -D ((git branch | Select-String -Pattern 'feature-*') | foreach{$_.ToString().Trim()})
// this will delete all branches that contains the word "feature-" as a substring.

You can also fine tune how the pattern matching should work using Powershell's Select-String command. Take a look at powershell docs.

On a Mac (pdftex) I managed to include a png file simply with \includegraphics[width=1.2\textwidth]{filename.png}. But in order for that to work I had to comment out the following 2 packages:

%\usepackage[dvips]{epsfig}

%\usepackage[dvips]{graphicx}

...and simply use package graphicx:

\usepackage{graphicx}

It seems [dvips] is problematic when used with pdftex.

Using @joran's sample data,

ggplot(dat, aes(x=xx, fill=yy)) + geom_histogram(alpha=0.2, position="identity")

note that the default position of geom_histogram is "stack."

see "position adjustment" of this page:

docs.ggplot2.org/current/geom_histogram.html

Thank God, Microsoft got that figured out in WPF :)

Every Control, like a progress bar, button, form, etc. has a Dispatcher on it. You can give the Dispatcher an Action that needs to be performed, and it will automatically call it on the correct thread (an Action is like a function delegate).

You can find an example here.

Of course, you'll have to have the control accessible from other classes, e.g. by making it public and handing a reference to the Window to your other class, or maybe by passing a reference only to the progress bar.

It's pretty straightforward using [ to extract:

grep will give you the position in which it matched your search pattern (unless you use value = TRUE).

grep("^G45", My.Data$x)
# [1] 2

Since you're searching within the values of a single column, that actually corresponds to the row index. So, use that with [ (where you would use My.Data[rows, cols] to get specific rows and columns).

My.Data[grep("^G45", My.Data$x), ]
#      x y
# 2 G459 2

The help-page for subset shows how you can use grep and grepl with subset if you prefer using this function over [. Here's an example.

subset(My.Data, grepl("^G45", My.Data$x))

As of R 3.3, there's now also the startsWith function, which you can again use with subset (or with any of the other approaches above). According to the help page for the function, it's considerably faster than using substring or grepl.

subset(My.Data, startsWith(as.character(x), "G45"))
#      x y
# 2 G459 2

The use-case for CORS is simple. Imagine the site alice.com has some data that the site bob.com wants to access. This type of request traditionally wouldn’t be allowed under the browser’s same origin policy. However, by supporting CORS requests, alice.com can add a few special response headers that allows bob.com to access the data. In order to understand it well, please visit this nice tutorial.. How to solve the issue of CORS

This works, but there might be better solutions.

asking="hello! what's your name?"
asking = ''.join([c for c in asking if c not in ('!', '?')])
print asking

Update

the library already have Java/Kotlin support, see github.

Original

To simplify I did a class to be used simply, I added it on Encryption library to use it you just do as follow:

Add the gradle library:

compile 'se.simbio.encryption:library:2.0.0'

and use it:

Encryption encryption = Encryption.getDefault("Key", "Salt", new byte[16]);
String encrypted = encryption.encryptOrNull("top secret string");
String decrypted = encryption.decryptOrNull(encrypted);

if you not want add the Encryption library you can just copy the following class to your project. If you are in an android project you need to import android Base64 in this class, if you are in a pure java project you need to add this class manually you can get it here

Encryption.java

It's not smart enough to realize it's still a "vector" in math terms.

Say rather that it's smart enough to recognize a difference in dimensionality. :-)

I think the simplest thing you can do is select that row positionally using iloc, which gives you a Series with the columns as the new index and the values as the values:

>>> df = pd.DataFrame([list(range(5))], columns=["a{}".format(i) for i in range(5)])
>>> df
   a0  a1  a2  a3  a4
0   0   1   2   3   4
>>> df.iloc[0]
a0    0
a1    1
a2    2
a3    3
a4    4
Name: 0, dtype: int64
>>> type(_)
<class 'pandas.core.series.Series'>

func playVideo(url: URL) {

    let player = AVPlayer(url: url)

    let layer: AVPlayerLayer = AVPlayerLayer(player: player)
    layer.backgroundColor = UIColor.white.cgColor
    layer.frame = CGRect(x: 0, y: 0, width: 300, height: 300)
    layer.videoGravity = .resizeAspectFill
    self.view.layer.addSublayer(layer)

These are use in ruby on rails :-

<% %> :-

The <% %> tags are used to execute Ruby code that does not return anything, such as conditions, loops or blocks. Eg :-

<h1>Names of all the people</h1>
<% @people.each do |person| %>
  Name: <%= person.name %><br>
<% end %>

<%= %> :-

use to display the content .

Name: <%= person.name %><br>

<% -%>:-

Rails extends ERB, so that you can suppress the newline simply by adding a trailing hyphen to tags in Rails templates

<%# %>:-

comment out the code

Just to add another option to Dónal's answer, you can also still use the good old java.lang.Object.getClass() method.

Yes, #id selectors combined with a multiple selector (comma) is perfectly valid in both jQuery and CSS.

However, for your example, since <script> comes before the elements, you need a document.ready handler, so it waits until the elements are in the DOM to go looking for them, like this:

<script>
  $(function() {
    $("#segement1,#segement2,#segement3").hide()
  });
</script>

<div id="segement1"></div>
<div id="segement2"></div>
<div id="segement3"></div>

I was encountering the same problem. I had a Tooltip component that was receiving showTooltip prop, that I was updating on Parent component based on an if condition, it was getting updated in Parent component but Tooltip component was not rendering.

const Parent = () => {
   let showTooltip = false;
   if(....){ showTooltip = true; }
   return(
      <Tooltip showTooltip={showTooltip}></Tooltip>
   )
}

The mistake I was doing is to declare showTooltip as a let.

I realized what I was doing wrong I was violating the principles of how rendering works, Replacing it with hooks did the job.

const [showTooltip, setShowTooltip] =  React.useState<boolean>(false);

If you have created your HTML element dynamically, you'll want to disable the attribute via JS. There is a little trap however:

When setting elem.contentEditable you can use either the boolean false or the string "false". But when you set elem.spellcheck, you can only use the boolean - for some reason. Your options are thus:

elem.spellcheck = false;

Or the option Mac provided in his answer:

elem.setAttribute("spellcheck", "false"); // Both string and boolean work here. 

You can use jquery for this:

$('body').bind('copy paste',function(e) {
    e.preventDefault(); return false; 
});

Using jQuery bind() and specififying your desired eventTypes .

If you don't want to use Scheduled Tasks you can use the Windows Subsystem for Linux which will allow you to use cron jobs like on Linux.

To make sure cron is actually running you can type service cron status from within the Linux terminal. If it isn't currently running then type service cron start and you should be good to go.

The simplest is to do a PivotChart. Select your array of dates (with a header) and create a new Pivot Chart (Insert / PivotChart / Ok) Then on the field list window, drag and drop the date column in the Axis list first and then in the value list first.

Step 1:

Step 2:

\B is not \b e.g. negative \b

pass-key here is no word boundary beside - so it matches \B in your first example there are word boundary beside cat so it matches \b

similar rules apply for others too. \W is negative of \w \UPPER CASE is negative of \LOWER CASE

The key to debugging situations like these is to run the subquery/inline view on its' own to see what the output is:

  SELECT TOP 1 
         dm.marker_value, 
         dum.profile_id
    FROM DPS_USR_MARKERS dum (NOLOCK)
    JOIN DPS_MARKERS dm (NOLOCK) ON dm.marker_id= dum.marker_id 
                                AND dm.marker_key = 'moneyBackGuaranteeLength'
ORDER BY dm.creation_date

Running that, you would see that the profile_id value didn't match the u.id value of u162231993, which would explain why any mbg references would return null (thanks to the left join; you wouldn't get anything if it were an inner join).

You've coded yourself into a corner using TOP, because now you have to tweak the query if you want to run it for other users. A better approach would be:

   SELECT u.id, 
          x.marker_value 
     FROM DPS_USER u
LEFT JOIN (SELECT dum.profile_id,
                  dm.marker_value,
                  dm.creation_date
             FROM DPS_USR_MARKERS dum (NOLOCK)
             JOIN DPS_MARKERS dm (NOLOCK) ON dm.marker_id= dum.marker_id 
                                         AND dm.marker_key = 'moneyBackGuaranteeLength'
           ) x ON x.profile_id = u.id
     JOIN (SELECT dum.profile_id,
                  MAX(dm.creation_date) 'max_create_date'
             FROM DPS_USR_MARKERS dum (NOLOCK)
             JOIN DPS_MARKERS dm (NOLOCK) ON dm.marker_id= dum.marker_id 
                                         AND dm.marker_key = 'moneyBackGuaranteeLength'
         GROUP BY dum.profile_id) y ON y.profile_id = x.profile_id
                                   AND y.max_create_date = x.creation_date
    WHERE u.id = 'u162231993'

With that, you can change the id value in the where clause to check records for any user in the system.

JsonNode root = mapper.readTree(json);
root.at("/some-node").fields().forEachRemaining(e -> {
                              System.out.println(e.getKey()+"---"+ e.getValue());

        });

If you want to rewrite the url, you have to change your site virtualhost adding this lines:

### Enabling mod_rewrite
Options FollowSymLinks
RewriteEngine on

### Rewrite http:// => https://
RewriteCond %{SERVER_PORT} 80$
RewriteRule ^(.*)$ https://%{HTTP_HOST}$1 [R=301,NC,L]

But, if you want to redirect all your requests on the port 80 to the port 443 of the web servers behind the proxy, you can try this example conf on your haproxy.cfg:

Restart your command prompt and check your path variable (type: path). If you can't find find nodejs installation dir from output add it to the path variable and remember to restart cdm again...

It should be:

context.TableName.AddObject(TableEntityInstance);

Where:

1. TableName: the name of the table in the database.
2. TableEntityInstance: an instance of the table entity class.

If your table is Orders, then:

Order order = new Order();
context.Orders.AddObject(order);

For example:

 var id = Guid.NewGuid();

 // insert
 using (var db = new EfContext("name=EfSample"))
 {
    var customers = db.Set<Customer>();
    customers.Add( new Customer { CustomerId = id, Name = "John Doe" } );

    db.SaveChanges();
 }

Here is a live example:

public void UpdatePlayerScreen(byte[] imageBytes, string installationKey)
{
  var player = (from p in this.ObjectContext.Players where p.InstallationKey == installationKey select p).FirstOrDefault();

  var current = (from d in this.ObjectContext.Screenshots where d.PlayerID == player.ID select d).FirstOrDefault();

  if (current != null)
  {
    current.Screen = imageBytes;
    current.Refreshed = DateTime.Now;

    this.ObjectContext.SaveChanges();
  }
  else
  {
    Screenshot screenshot = new Screenshot();

    screenshot.ID = Guid.NewGuid();
    screenshot.Interval = 1000;
    screenshot.IsTurnedOn = true;
    screenshot.PlayerID = player.ID;
    screenshot.Refreshed = DateTime.Now;
    screenshot.Screen = imageBytes;

    this.ObjectContext.Screenshots.AddObject(screenshot);
    this.ObjectContext.SaveChanges();
  }
}

Well it depends on how you want to call this code.

Are you calling it from a button click on a form, if so then on the properties for the button on form, go to the Event tab, then On Click item, select [Event Procedure]. This will open the VBA code window for that button. You would then call your Module.Routine and then this would trigger when you click the button.

Similar to this:

Private Sub Command1426_Click()
    mdl_ExportMorning.ExportMorning
End Sub

This button click event calls the Module mdl_ExportMorning and the Public Sub ExportMorning.

A more explicit option is to project collection to an IEnumerable of KeyValuePair and then convert it to a Dictionary.

Dictionary<int, string> dictionary = objects
    .Select(x=> new KeyValuePair<int, string>(x.Id, x.Name))
    .ToDictionary(x=>x.Key, x=>x.Value);

In simple way, you can use the following code to clear all the text field, textarea, dropdown, radio button, checkbox in a form.

function reset(){
    $('input[type=text]').val('');  
    $('#textarea').val(''); 
    $('input[type=select]').val('');
    $('input[type=radio]').val('');
    $('input[type=checkbox]').val('');  
}

Simple way to differentiate UTF-8 and UTF-16 is to identify commonalities between them.

Other than sharing same unicode number for given character, each one is their own format.

UTF-8 try to represent, every unicode number given to character with one byte(If it is ASCII), else 2 two bytes, else 4 bytes and so on...

UTF-16 try to represent, every unicode number given to character with two byte to start with. If two bytes are not sufficient, then uses 4 bytes. IF that is also not sufficient, then uses 6 bytes.

Theoretically, UTF-16 is more space efficient, but in practical UTF-8 is more space efficient as most of the characters(98% of data) for processing are ASCII and UTF-8 try to represent them with single byte and UTF-16 try to represent them with 2 bytes.

Also, UTF-8 is superset of ASCII encoding. So every app that expects ASCII data would also accepted by UTF-8 processor. This is not true for UTF-16. UTF-16 could not understand ASCII, and this is big hurdle for UTF-16 adoption.

Another point to note is, all UNICODE as of now could be fit in 4 bytes of UTF-8 maximum(Considering all languages of world). This is same as UTF-16 and no real saving in space compared to UTF-8 ( https://stackoverflow.com/a/8505038/3343801 )

So, people use UTF-8 where ever possible.

just go into XML file and give id to your webView then in java paste these line:

   public class Main extends Activity {

private WebView mWebview;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.Your_layout_file_name);

    mWebview = (WebView)findViewById(R.id.id_you_gave _to_your_wenview_in_xml);
    mWebview.loadUrl("http://www.google.com");
    }   
}

As of powershell 5.0, you can now use the -Depth parameter in Get-ChildItem!

You combine it with -Recurse to limit the recursion.

Get-ChildItem -Recurse -Depth 2

Try using os.makedirs:

import os
import errno

try:
    os.makedirs(<path>)
except OSError as e:
    if errno.EEXIST != e.errno:
        raise

You can use jQuery serialize function along with get/post as follows:

$.get('server.php?' + $('#theForm').serialize())

$.post('server.php', $('#theform').serialize())

jQuery Serialize Documentation: http://api.jquery.com/serialize/

Simple AJAX submit using jQuery:

// this is the id of the submit button
$("#submitButtonId").click(function() {

    var url = "path/to/your/script.php"; // the script where you handle the form input.

    $.ajax({
           type: "POST",
           url: url,
           data: $("#idForm").serialize(), // serializes the form's elements.
           success: function(data)
           {
               alert(data); // show response from the php script.
           }
         });

    return false; // avoid to execute the actual submit of the form.
});

Here is some example code to help you get started:

package com.acme;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class FileArrayProvider {

    public String[] readLines(String filename) throws IOException {
        FileReader fileReader = new FileReader(filename);
        BufferedReader bufferedReader = new BufferedReader(fileReader);
        List<String> lines = new ArrayList<String>();
        String line = null;
        while ((line = bufferedReader.readLine()) != null) {
            lines.add(line);
        }
        bufferedReader.close();
        return lines.toArray(new String[lines.size()]);
    }
}

And an example unit test:

package com.acme;

import java.io.IOException;

import org.junit.Test;

public class FileArrayProviderTest {

    @Test
    public void testFileArrayProvider() throws IOException {
        FileArrayProvider fap = new FileArrayProvider();
        String[] lines = fap
                .readLines("src/main/java/com/acme/FileArrayProvider.java");
        for (String line : lines) {
            System.out.println(line);
        }
    }
}

Hope this helps.

input[type='checkbox', name='ProductCode']

That's the CSS way and I'm almost sure it will work in jQuery.

I have tried lots of different solutions available on internet but solution which works for me is available at below link.

https://www.java67.com/2017/07/how-to-sort-arraylist-of-objects-using.html

Pointer Lock API

While the cursor: none CSS solution is definitely a solid and easy workaround, if your actual goal is to remove the default cursor while your web application is being used, or implement your own interpretation of raw mouse movement (for FPS games, for example), you might want to consider using the Pointer Lock API instead.

You can use requestPointerLock on an element to remove the cursor, and redirect all mousemove events to that element (which you may or may not handle):

document.body.requestPointerLock();

To release the lock, you can use exitPointerLock:

document.exitPointerLock();

Additional notes

No cursor, for real

This is a very powerful API call. It not only renders your cursor invisible, but it actually removes your operating system's native cursor. You won't be able to select text, or do anything with your mouse (except listening to some mouse events in your code) until the pointer lock is released (either by using exitPointerLock or pressing ESC in some browsers).

That is, you cannot leave the window with your cursor for it to show again, as there is no cursor.

Restrictions

As mentioned above, this is a very powerful API call, and is thus only allowed to be made in response to some direct user-interaction on the web, such as a click; for example:

document.addEventListener("click", function () {
    document.body.requestPointerLock();
});

Also, requestPointerLock won't work from a sandboxed iframe unless the allow-pointer-lock permission is set.

User-notifications

Some browsers will prompt the user for a confirmation before the lock is engaged, some will simply display a message. This means pointer lock might not activate right away after the call. However, the actual activation of pointer locking can be listened to by listening to the pointerchange event on the element on which requestPointerLock was called:

document.body.addEventListener("pointerlockchange", function () {
    if (document.pointerLockElement === document.body) {
        // Pointer is now locked to <body>.
    }
});

Most browsers will only display the message once, but Firefox will occasionally spam the message on every single call. AFAIK, this can only be worked around by user-settings, see Disable pointer-lock notification in Firefox.

Listening to raw mouse movement

The Pointer Lock API not only removes the mouse, but instead redirects raw mouse movement data to the element requestPointerLock was called on. This can be listened to simply by using the mousemove event, then accessing the movementX and movementY properties on the event object:

document.body.addEventListener("mousemove", function (e) {
    console.log("Moved by " + e.movementX + ", " + e.movementY);
});

Save image to bitmap variable

using (var ms = new MemoryStream())
{
    Bitmap bmp = new Bitmap(imageToConvert);
    bmp.Save(ms, format);
    return ms.ToArray();
}

var fs = require("fs");
var filename = "./index.html";

function start(resp) {
    resp.writeHead(200, {
        "Content-Type": "text/html"
    });
    fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        resp.write(data);
        resp.end();
    });
}

I have a similar solution to the above and it works for opening, saving, file selecting. I paste it into its own module and use in all the Access DB's I create. As the code states it requires Microsoft Office 14.0 Object Library. Just another option I suppose:

Public Function Select_File(InitPath, ActionType, FileType)
    ' Requires reference to Microsoft Office 14.0 Object Library.

    Dim fDialog As Office.FileDialog
    Dim varFile As Variant


    If ActionType = "FilePicker" Then
        Set fDialog = Application.FileDialog(msoFileDialogFilePicker)
        ' Set up the File Dialog.
    End If
    If ActionType = "SaveAs" Then
        Set fDialog = Application.FileDialog(msoFileDialogSaveAs)
    End If
    If ActionType = "Open" Then
        Set fDialog = Application.FileDialog(msoFileDialogOpen)
    End If
    With fDialog
        .AllowMultiSelect = False
        ' Disallow user to make multiple selections in dialog box
        .Title = "Please specify the file to save/open..."
        ' Set the title of the dialog box.
        If ActionType <> "SaveAs" Then
            .Filters.Clear
            ' Clear out the current filters, and add our own.
            .Filters.Add FileType, "*." & FileType
        End If
        .InitialFileName = InitPath
        ' Show the dialog box. If the .Show method returns True, the
        ' user picked a file. If the .Show method returns
        ' False, the user clicked Cancel.
        If .Show = True Then
        'Loop through each file selected and add it to our list box.
            For Each varFile In .SelectedItems
                'return the subroutine value as the file path & name selected
                Select_File = varFile
            Next
        End If
    End With
End Function

For modern web browsers (After IE9)

See the Duplicate listed at the top of the page for correct information!

See answer here: How to control web page caching, across all browsers?

For IE9 and before

Do not blindly copy paste this!

The list is just examples of different techniques, it's not for direct insertion. If copied, the second would overwrite the first and the fourth would overwrite the third because of the http-equiv declarations AND fail with the W3C validator. At most, one could have one of each http-equiv declarations; pragma, cache-control and expires. These are completely outdated when using modern up to date browsers. After IE9 anyway. Chrome and Firefox specifically does not work with these as you would expect, if at all.

<meta http-equiv="cache-control" content="max-age=0" />
<meta http-equiv="cache-control" content="no-cache" />
<meta http-equiv="expires" content="0" />
<meta http-equiv="expires" content="Tue, 01 Jan 1980 1:00:00 GMT" />
<meta http-equiv="pragma" content="no-cache" />

Actually do not use these at all!

Caching headers are unreliable in meta elements; for one, any web proxies between the site and the user will completely ignore them. You should always use a real HTTP header for headers such as Cache-Control and Pragma.

|| is the or operator.

if(A || B){ do something }

#include <stdio.h>
main()
{
    char str[100];
    int num;
    while(1) {
        printf("Enter a number: ");
        scanf("%[^0-9]%d",str,&num);
        printf("You entered the number %d\n",num);
    }
    return 0;
}

%[^0-9] in scanf() gobbles up all that is not between 0 and 9. Basically it cleans the input stream of non-digits and puts it in str. Well, the length of non-digit sequence is limited to 100. The following %d selects only integers in the input stream and places it in num.

Create a script with name your-app.service (rest-app.service). We should place this script in /etc/systemd/system directory. Here is the sample content of the script

[Unit]
Description=Spring Boot REST Application
After=syslog.target

[Service]
User=javadevjournal
ExecStart=/var/rest-app/restdemo.jar
SuccessExitStatus=200

[Install]
WantedBy=multi-user.target

Next:

 service rest-app start

As many have already answered, mounting host volumes during the build is not possible. I just would like to add docker-compose way, I think it'll be nice to have, mostly for development/testing usage

Dockerfile

FROM node:10
WORKDIR /app
COPY . .
RUN npm ci
CMD sleep 999999999

docker-compose.yml

version: '3'
services:
  test-service:
    image: test/image
    build:
      context: .
      dockerfile: Dockerfile
    container_name: test
    volumes:
      - ./export:/app/export
      - ./build:/app/build

And run your container by docker-compose up -d --build

You can do this by displaying a div (if you want to do it in a modal manner you could use blockUI - or one of the many other modal dialog plugins out there) prior to the request then just waiting until the call back succeeds as a quick example you can you $.getJSON as follows (you might want to use .ajax if you want to add proper error handling)

$("#ajaxLoader").show(); //Or whatever you want to do
$.getJSON("/AJson/Call/ThatTakes/Ages", function(result) {
    //Process your response
    $("#ajaxLoader").hide();
});

If you do this several times in your app and want to centralise the behaviour for all ajax calls you can make use of the global AJAX events:-

$("#ajaxLoader").ajaxStart(function() { $(this).show(); })
               .ajaxStop(function() { $(this).hide(); });

Using blockUI is similar for example with mark up like:-

<a href="/Path/ToYourJson/Action" id="jsonLink">Get JSON</a>
<div id="resultContainer" style="display:none">
And the answer is:-
    <p id="result"></p>
</div>

<div id="ajaxLoader" style="display:none">
    <h2>Please wait</h2>
    <p>I'm getting my AJAX on!</p>
</div>

And using jQuery:-

$(function() {
    $("#jsonLink").click(function(e) {
        $.post(this.href, function(result) {
            $("#resultContainer").fadeIn();
            $("#result").text(result.Answer);
        }, "json");
        return false;
    });
    $("#ajaxLoader").ajaxStart(function() {
                          $.blockUI({ message: $("#ajaxLoader") });
                     })
                    .ajaxStop(function() { 
                          $.unblockUI();
                     });
});

Try it:

def showDf(df, count=None, percent=None, maxColumns=0):
    if (df == None): return
    import pandas
    from IPython.display import display
    pandas.set_option('display.encoding', 'UTF-8')
    # Pandas dataframe
    dfp = None
    # maxColumns param
    if (maxColumns >= 0):
        if (maxColumns == 0): maxColumns = len(df.columns)
        pandas.set_option('display.max_columns', maxColumns)
    # count param
    if (count == None and percent == None): count = 10 # Default count
    if (count != None):
        count = int(count)
        if (count == 0): count = df.count()
        pandas.set_option('display.max_rows', count)
        dfp = pandas.DataFrame(df.head(count), columns=df.columns)
        display(dfp)
    # percent param
    elif (percent != None):
        percent = float(percent)
        if (percent >=0.0 and percent <= 1.0):
            import datetime
            now = datetime.datetime.now()
            seed = long(now.strftime("%H%M%S"))
            dfs = df.sample(False, percent, seed)
            count = df.count()
            pandas.set_option('display.max_rows', count)
            dfp = dfs.toPandas()    
            display(dfp)

Examples of usages are:

# Shows the ten first rows of the Spark dataframe
showDf(df)
showDf(df, 10)
showDf(df, count=10)

# Shows a random sample which represents 15% of the Spark dataframe
showDf(df, percent=0.15) 

You can add the TextField as a child to a Container that has a BoxDecoration with border property:

new Container(
  margin: const EdgeInsets.all(15.0),
  padding: const EdgeInsets.all(3.0),
  decoration: BoxDecoration(
    border: Border.all(color: Colors.blueAccent)
  ),
  child: Text("My Awesome Border"),
)

Add your <script> to the bottom of your <body>, or add an event listener for DOMContentLoaded following this StackOverflow question.

If that script executes in the <head> section of the code, document.getElementsByClassName(...) will return an empty array because the DOM is not loaded yet.

You're getting the Type Error because you're referencing search_span[0], but search_span[0] is undefined.

This works when you execute it in Dev Tools because the DOM is already loaded.

If you are using Python on Ubuntu and you only want it to work on Ubuntu a substantially faster way is the use the terminal's locate program like this.

import subprocess

def find_files(file_name):
    command = ['locate', file_name]

    output = subprocess.Popen(command, stdout=subprocess.PIPE).communicate()[0]
    output = output.decode()

    search_results = output.split('\n')

    return search_results

search_results is a list of the absolute file paths. This is 10,000's of times faster than the methods above and for one search I've done it was ~72,000 times faster.

(I presume that you've concluded that it's an iptables problem by dropping the firewall completely (iptables -P INPUT ACCEPT; iptables -P OUTPUT ACCEPT; iptables -F) and confirmed that you can connect to the MySQL server from your Windows box?)

Some previous rule in the INPUT table is probably rejecting or dropping the packet. You can get around that by inserting the new rule at the top, although you might want to review your existing rules to see whether that's sensible:

iptables -I INPUT 1 -p tcp --dport 3306 -j ACCEPT

Note that iptables-save won't save the new rule persistently (i.e. across reboots) - you'll need to figure out something else for that. My usual route is to store the iptables-save output in a file (/etc/network/iptables.rules or similar) and then load then with a pre-up statement in /etc/network/interfaces).

This is a very frustrating part of XCode. Like many, I wasted hours on this when I switched to a newer version of xcode (version 8). The solution for me was to open the properties for my project and under the "App Icons and Launch Images" choose the "migrate" option for the icons. This made absolutely no sense to me as I already had all my icons there, but it worked! Unfortunately I now seem to have two copies of my launcher icons in the project though.

I am getting the error (...) javax.naming.NameNotFoundException: greetJndi not bound

This means that nothing is bound to the jndi name greetJndi, very likely because of a deployment problem given the incredibly low quality of this tutorial (check the server logs). I'll come back on this.

Is there any specific directory structure to deploy in JBoss?

The internal structure of the ejb-jar is supposed to be like this (using the poor naming conventions and the default package as in the mentioned link):

.
+-- greetBean.java
+-- greetHome.java
+-- greetRemote.java
+-- META-INF
    +-- ejb-jar.xml
    +-- jboss.xml

But as already mentioned, this tutorial is full of mistakes:

• there is an extra character (<enterprise-beans>] <-- HERE) in the ejb-jar.xml (!)
• a space is missing after PUBLIC in the ejb-jar.xml and jboss.xml (!!)
• the jboss.xml is incorrect, it should contain a session element instead of entity (!!!)

Here is a "fixed" version of the ejb-jar.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">
<ejb-jar>
  <enterprise-beans>
    <session>
      <ejb-name>greetBean</ejb-name>
      <home>greetHome</home>
      <remote>greetRemote</remote>
      <ejb-class>greetBean</ejb-class>
      <session-type>Stateless</session-type>
      <transaction-type>Container</transaction-type>
    </session>
  </enterprise-beans>
</ejb-jar>

And of the jboss.xml:

<?xml version="1.0"?>
<!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 3.2//EN" "http://www.jboss.org/j2ee/dtd/jboss_3_2.dtd">
<jboss>
  <enterprise-beans>
    <session>
      <ejb-name>greetBean</ejb-name>
      <jndi-name>greetJndi</jndi-name>
    </session>
  </enterprise-beans>
</jboss>

After doing these changes and repackaging the ejb-jar, I was able to successfully deploy it:

21:48:06,512 INFO  [Ejb3DependenciesDeployer] Encountered deployment AbstractVFSDeploymentContext@5060868{vfszip:/home/pascal/opt/jboss-5.1.0.GA/server/default/deploy/greet.jar/}

21:48:06,805 INFO  [ProxyFactory] Bound EJB Home 'greetBean' to jndi 'greetJndi'

That tutorial needs significant improvement; I'd advise from staying away from roseindia.net.

You can find answer in depth here.

But in general with float you need to be aware and take care of the surrounding elements and inline-block simple way to line elements.

Thanks

I wanted to add something very important. I use JohnnyHK method a lot but I noticed sometimes the changes didn't persist to the database. When I used .markModified it worked.

User.findOne({username: oldUsername}, function (err, user) {
   user.username = newUser.username;
   user.password = newUser.password;
   user.rights = newUser.rights;

   user.markModified(username)
   user.markModified(password)
   user.markModified(rights)
    user.save(function (err) {
    if(err) {
        console.error('ERROR!');
    }
});
});

tell mongoose about the change with doc.markModified('pathToYourDate') before saving.

Modifications to sys.path only apply for the life of that Python interpreter. If you want to do it permanently you need to modify the PYTHONPATH environment variable:

PYTHONPATH="/Me/Documents/mydir:$PYTHONPATH"
export PYTHONPATH

Note that PATH is the system path for executables, which is completely separate.

**You can write the above in ~/.bash_profile and the source it using source ~/.bash_profile

If you really want to create an array rather than a list use either

String[] names = ["lucas", "Fred", "Mary"]

or

def names = ["lucas", "Fred", "Mary"].toArray()

In phpmyadmin, If you need to add a boolean datatype column to an existing table with default value true:

ALTER TABLE books
   isAvailable boolean default true;

When you’re faced with a problem to solve (and frankly, who isn’t these days?), the basic strategy usually taken by we computer people is called “divide and conquer.” It goes like this:

• Conceptualize the specific problem as a set of smaller sub-problems.
• Solve each smaller problem.
• Combine the results into a solution of the specific problem.

But “divide and conquer” is not the only possible strategy. We can also take a more generalist approach:

• Conceptualize the specific problem as a special case of a more general problem.
• Somehow solve the general problem.
• Adapt the solution of the general problem to the specific problem.

- Eric Lippert

I believe many solutions already exist for this problem in server-side languages such as ASP.Net/C#.

I've outlined some of the major aspects of the problem

• Issue: We need to load data only for the desired language

  Solution: For this purpose we save data to a separate files for each language

ex. res.de.js, res.fr.js, res.en.js, res.js(for default language)

• Issue: Resource files for each page should be separated so we only get the data we need

  Solution: We can use some tools that already exist like https://github.com/rgrove/lazyload

• Issue: We need a key/value pair structure to save our data

  Solution: I suggest a javascript object instead of string/string air. We can benefit from the intellisense from an IDE

• Issue: General members should be stored in a public file and all pages should access them

  Solution: For this purpose I make a folder in the root of web application called Global_Resources and a folder to store global file for each sub folders we named it 'Local_Resources'

• Issue: Each subsystems/subfolders/modules member should override the Global_Resources members on their scope

  Solution: I considered a file for each

Application Structure

root/
    Global_Resources/
        default.js
        default.fr.js
    UserManagementSystem/
        Local_Resources/
            default.js
            default.fr.js
            createUser.js
        Login.htm
        CreateUser.htm

The corresponding code for the files:

Global_Resources/default.js

var res = {
    Create : "Create",
    Update : "Save Changes",
    Delete : "Delete"
};

Global_Resources/default.fr.js

var res = {
    Create : "créer",
    Update : "Enregistrer les modifications",
    Delete : "effacer"
};

The resource file for the desired language should be loaded on the page selected from Global_Resource - This should be the first file that is loaded on all the pages.

UserManagementSystem/Local_Resources/default.js

res.Name = "Name";
res.UserName = "UserName";
res.Password = "Password";

UserManagementSystem/Local_Resources/default.fr.js

res.Name = "nom";
res.UserName = "Nom d'utilisateur";
res.Password = "Mot de passe";

UserManagementSystem/Local_Resources/createUser.js

// Override res.Create on Global_Resources/default.js
res.Create = "Create User"; 

UserManagementSystem/Local_Resources/createUser.fr.js

// Override Global_Resources/default.fr.js
res.Create = "Créer un utilisateur";

manager.js file (this file should be load last)

res.lang = "fr";

var globalResourcePath = "Global_Resources";
var resourceFiles = [];

var currentFile = globalResourcePath + "\\default" + res.lang + ".js" ;

if(!IsFileExist(currentFile))
    currentFile = globalResourcePath + "\\default.js" ;
if(!IsFileExist(currentFile)) throw new Exception("File Not Found");

resourceFiles.push(currentFile);

// Push parent folder on folder into folder
foreach(var folder in parent folder of current page)
{
    currentFile = folder + "\\Local_Resource\\default." + res.lang + ".js";

    if(!IsExist(currentFile))
        currentFile = folder + "\\Local_Resource\\default.js";
    if(!IsExist(currentFile)) throw new Exception("File Not Found");

    resourceFiles.push(currentFile);
}

for(int i = 0; i < resourceFiles.length; i++) { Load.js(resourceFiles[i]); }

// Get current page name
var pageNameWithoutExtension = "SomePage";

currentFile = currentPageFolderPath + pageNameWithoutExtension + res.lang + ".js" ;

if(!IsExist(currentFile))
    currentFile = currentPageFolderPath + pageNameWithoutExtension + ".js" ;
if(!IsExist(currentFile)) throw new Exception("File Not Found");

Hope it helps :)

I had the same problem, my database log file size was about 39 gigabyte, and after shrinking (both database and files) it reduced to 37 gigabyte that was not enough, so I did this solution: (I did not need the ldf file (log file) anymore)

(**Important) : Get a full backup of your database before the process.

1. Run "checkpoint" on that database.

2. Detach that database (right click on the database and chose tasks >> Detach...) {if you see an error, do the steps in the end of this text}

3. Move MyDatabase.ldf to another folder, you can find it in your hard disk in the same folder as your database (Just in case you need it in the future for some reason such as what user did some task).

4. Attach the database (right click on Databases and chose Attach...)

5. On attach dialog remove the .ldf file (which shows 'file not found' comment) and click Ok. (don`t worry the ldf file will be created after the attachment process.)

6. After that, a new log file create with a size of 504 KB!!!.

In step 2, if you faced an error that database is used by another user, you can:

1.run this command on master database "sp_who2" and see what process using your database.

2.read the process number, for example it is 52 and type "kill 52", now your database is free and ready to detach.

If the number of processes using your database is too much:

1.Open services (type services in windows start) find SQL Server ... process and reset it (right click and chose reset).

2. Immediately click Ok button in the detach dialog box (that showed the detach error previously).

I think Todd is correct, but I think there's one other thing you should consider. You can reliably get the home directory from the JVM at runtime, and then you can create files objects relative to that location. It's not that much more trouble, and it's something you'll appreciate if you ever move to another computer or operating system.

File homedir = new File(System.getProperty("user.home"));
File fileToRead = new File(homedir, "java/ex.txt");

Create your custom navigation and give them classes you want, then you are ready to go. it's simple as that.

Let's see an example:

<div class="owl-carousel">_x000D_
      <div class="single_img"><img src="1.png" alt=""></div>_x000D_
      <div class="single_img"><img src="2.png" alt=""></div>_x000D_
      <div class="single_img"><img src="3.png" alt=""></div>_x000D_
      <div class="single_img"><img src="4.png" alt=""></div>_x000D_
</div>_x000D_
  _x000D_
<div class="slider_nav">_x000D_
 <button class="am-next">Next</button>_x000D_
 <button class="am-prev">Previous</button>_x000D_
</div>

In your js file you can do the following:

 $(".owl-carousel").owlCarousel({_x000D_
    // you can use jQuery selector_x000D_
    navText: [$('.am-next'),$('.am-prev')]_x000D_
 _x000D_
});

If you really want to layout manually, i'd suggest not to use a standard layout at all. Do it all on your own, here a kotlin example:

class ProgrammaticalLayout @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0) : ViewGroup(context, attrs, defStyleAttr) { 
    private val firstTextView = TextView(context).apply {
        test = "First Text"
    }

    private val secondTextView = TextView(context).apply {
        text = "Second Text"
    }

    init {
        addView(firstTextView)
        addView(secondTextView)
    }

    override fun onLayout(changed: Boolean, left: Int, top: Int, right: Int, bottom: Int) {
        // center the views verticaly and horizontaly
        val firstTextLeft = (measuredWidth - firstTextView.measuredWidth) / 2
        val firstTextTop = (measuredHeight - (firstTextView.measuredHeight + secondTextView.measuredHeight)) / 2
        firstTextView.layout(firstTextLeft,firstTextTop, firstTextLeft + firstTextView.measuredWidth,firstTextTop + firstTextView.measuredHeight)

        val secondTextLeft = (measuredWidth - secondTextView.measuredWidth) / 2
        val secondTextTop = firstTextView.bottom
        secondTextView.layout(secondTextLeft,secondTextTop, secondTextLeft + secondTextView.measuredWidth,secondTextTop + secondTextView.measuredHeight)
    }

    override fun onMeasure(widthMeasureSpec: Int, heightMeasureSpec: Int) { 
        // just assume we`re getting measured exactly by the parent
        val measuredWidth = MeasureSpec.getSize(widthMeasureSpec)
        val measuredHeight = MeasureSpec.getSize(heightMeasureSpec)

        firstTextView.measures(MeasureSpec.makeMeasureSpec(meeasuredWidth, MeasureSpec.AT_MOST), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED))
        secondTextView.measures(MeasureSpec.makeMeasureSpec(meeasuredWidth, MeasureSpec.AT_MOST), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED))

        setMeasuredDimension(measuredWidth, measuredHeight)
    }
}

This might give you an idea how this could work

In the case you are on something else then windows and your boss is forcing you to use azure devops, and you don't want to use SSH, and you want to use to plain old way, do the following.

You have to enable 'Alternate credentials' (I know it's annoying) or you need to create an access token. Creating an access token in this case is more like a temporary random password. If you use the windows tooling it is done for you.

Any way, go to Security in the profile context menu in the right upper corner.

Then if your boss/manager/dude that has the admin rights is favoring you the 'Alternate credentials' are enabled. Otherwise accept your fate and generate a 'Personal access token'.

If i go by Grodriguez's answer

System.out.println("" + value);
value = value.setScale(0, BigDecimal.ROUND_HALF_UP);
System.out.println("" + value);

This is the output

100.23 -> 100
100.77 -> 101

Which isn't quite what i want, so i ended up doing this..

System.out.println("" + value);
value = value.setScale(0, BigDecimal.ROUND_HALF_UP);
value = value.setScale(2, BigDecimal.ROUND_HALF_UP);
System.out.println("" + value);

This is what i get

100.23 -> 100.00
100.77 -> 101.00

This solves my problem for now .. : ) Thank you all.

From SQL Server 2016 you can use

DROP TABLE IF EXISTS dbo.Scores

Reference: DROP IF EXISTS - new thing in SQL Server 2016

It will be in SQL Azure Database soon.

It's not open source, but you can at least get a free personal use license to Prince, which really does a lovely job.

I had similar problem while using Silverlight web project...

I got resolved issue by setting startup page (In silverlight .aspx is the startup page).

In project browser right click your startup page and set it.!

see here my screen shot

You missed single quote sign:

SELECT * 
FROM TABLENAME 
WHERE DateTime >= '12/04/2011 12:00:00 AM' AND DateTime <= '25/05/2011 3:53:04 AM'

Also, it is recommended to use ISO8601 format YYYY-MM-DDThh:mm:ss.nnn[ Z ], as this one will not depend on your server's local culture.

SELECT *
FROM TABLENAME 
WHERE 
    DateTime >= '2011-04-12T00:00:00.000' AND 
    DateTime <= '2011-05-25T03:53:04.000'

I think .myi you can repair from inside mysql.

If you see these type of error messages from MySQL: Database failed to execute query (query) 1016: Can't open file: 'sometable.MYI'. (errno: 145) Error Msg: 1034: Incorrect key file for table: 'sometable'. Try to repair it thenb you probably have a crashed or corrupt table.

You can check and repair the table from a mysql prompt like this:

check table sometable;
+------------------+-------+----------+----------------------------+
| Table | Op | Msg_type | Msg_text | 
+------------------+-------+----------+----------------------------+ 
| yourdb.sometable | check | warning | Table is marked as crashed | 
| yourdb.sometable | check | status | OK | 
+------------------+-------+----------+----------------------------+ 

repair table sometable;
+------------------+--------+----------+----------+ 
| Table | Op | Msg_type | Msg_text | 
+------------------+--------+----------+----------+ 
| yourdb.sometable | repair | status | OK | 
+------------------+--------+----------+----------+

and now your table should be fine:

check table sometable;
+------------------+-------+----------+----------+ 
| Table | Op | Msg_type | Msg_text |
+------------------+-------+----------+----------+ 
| yourdb.sometable | check | status | OK |
+------------------+-------+----------+----------+

In the next major version of the library HttpClient interface is going to extend Closeable. Until then it is recommended to use CloseableHttpClient if compatibility with earlier 4.x versions (4.0, 4.1 and 4.2) is not required.

Linux kernel 5.0 source comments

I knew that x86 specifics are under arch/x86, and that syscall stuff goes under arch/x86/entry. So a quick git grep rdi in that directory leads me to arch/x86/entry/entry_64.S:

/*
 * 64-bit SYSCALL instruction entry. Up to 6 arguments in registers.
 *
 * This is the only entry point used for 64-bit system calls.  The
 * hardware interface is reasonably well designed and the register to
 * argument mapping Linux uses fits well with the registers that are
 * available when SYSCALL is used.
 *
 * SYSCALL instructions can be found inlined in libc implementations as
 * well as some other programs and libraries.  There are also a handful
 * of SYSCALL instructions in the vDSO used, for example, as a
 * clock_gettimeofday fallback.
 *
 * 64-bit SYSCALL saves rip to rcx, clears rflags.RF, then saves rflags to r11,
 * then loads new ss, cs, and rip from previously programmed MSRs.
 * rflags gets masked by a value from another MSR (so CLD and CLAC
 * are not needed). SYSCALL does not save anything on the stack
 * and does not change rsp.
 *
 * Registers on entry:
 * rax  system call number
 * rcx  return address
 * r11  saved rflags (note: r11 is callee-clobbered register in C ABI)
 * rdi  arg0
 * rsi  arg1
 * rdx  arg2
 * r10  arg3 (needs to be moved to rcx to conform to C ABI)
 * r8   arg4
 * r9   arg5
 * (note: r12-r15, rbp, rbx are callee-preserved in C ABI)
 *
 * Only called from user space.
 *
 * When user can change pt_regs->foo always force IRET. That is because
 * it deals with uncanonical addresses better. SYSRET has trouble
 * with them due to bugs in both AMD and Intel CPUs.
 */

and for 32-bit at arch/x86/entry/entry_32.S:

/*
 * 32-bit SYSENTER entry.
 *
 * 32-bit system calls through the vDSO's __kernel_vsyscall enter here
 * if X86_FEATURE_SEP is available.  This is the preferred system call
 * entry on 32-bit systems.
 *
 * The SYSENTER instruction, in principle, should *only* occur in the
 * vDSO.  In practice, a small number of Android devices were shipped
 * with a copy of Bionic that inlined a SYSENTER instruction.  This
 * never happened in any of Google's Bionic versions -- it only happened
 * in a narrow range of Intel-provided versions.
 *
 * SYSENTER loads SS, ESP, CS, and EIP from previously programmed MSRs.
 * IF and VM in RFLAGS are cleared (IOW: interrupts are off).
 * SYSENTER does not save anything on the stack,
 * and does not save old EIP (!!!), ESP, or EFLAGS.
 *
 * To avoid losing track of EFLAGS.VM (and thus potentially corrupting
 * user and/or vm86 state), we explicitly disable the SYSENTER
 * instruction in vm86 mode by reprogramming the MSRs.
 *
 * Arguments:
 * eax  system call number
 * ebx  arg1
 * ecx  arg2
 * edx  arg3
 * esi  arg4
 * edi  arg5
 * ebp  user stack
 * 0(%ebp) arg6

glibc 2.29 Linux x86_64 system call implementation

Now let's cheat by looking at a major libc implementations and see what they are doing.

What could be better than looking into glibc that I'm using right now as I write this answer? :-)

glibc 2.29 defines x86_64 syscalls at sysdeps/unix/sysv/linux/x86_64/sysdep.h and that contains some interesting code, e.g.:

/* The Linux/x86-64 kernel expects the system call parameters in
   registers according to the following table:

    syscall number  rax
    arg 1       rdi
    arg 2       rsi
    arg 3       rdx
    arg 4       r10
    arg 5       r8
    arg 6       r9

    The Linux kernel uses and destroys internally these registers:
    return address from
    syscall     rcx
    eflags from syscall r11

    Normal function call, including calls to the system call stub
    functions in the libc, get the first six parameters passed in
    registers and the seventh parameter and later on the stack.  The
    register use is as follows:

     system call number in the DO_CALL macro
     arg 1      rdi
     arg 2      rsi
     arg 3      rdx
     arg 4      rcx
     arg 5      r8
     arg 6      r9

    We have to take care that the stack is aligned to 16 bytes.  When
    called the stack is not aligned since the return address has just
    been pushed.


    Syscalls of more than 6 arguments are not supported.  */

and:

/* Registers clobbered by syscall.  */
# define REGISTERS_CLOBBERED_BY_SYSCALL "cc", "r11", "cx"

#undef internal_syscall6

    : "memory", REGISTERS_CLOBBERED_BY_SYSCALL);            \
    (long int) resultvar;                       \
})

which I feel are pretty self explanatory. Note how this seems to have been designed to exactly match the calling convention of regular System V AMD64 ABI functions: https://en.wikipedia.org/wiki/X86_calling_conventions#List_of_x86_calling_conventions

Quick reminder of the clobbers:

• cc means flag registers. But Peter Cordes comments that this is unnecessary here.
• memory means that a pointer may be passed in assembly and used to access memory

Tools - Android - Sdk manager - tab Sdk tools - install emulator 25.3.1

I had the same problem. I tried everything listed on this page. When I re-installed Composer it worked like before. I had a PHP version mismatch that was corrected with a new install establishing the dependencies with the PHP path installed in my system environment variables.

I DO NOT RECOMMEND the composer config -g -- disable-tls true approach.

By the way the way to reverse this is composer config -g -- disable-tls false.

i hope this will work too, try using"is_null"

<?php 
$web = the_field('website');
if (!is_null($web)) {
?>

....html code here

<?php
} else { 
    echo "Niente";
}
?>

http://php.net/manual/en/function.is-null.php

hope that suits you..

if you use

angularjs

you have just to write the right css in order to frame you div html code

<div 
style="height:51px;width:111px;margin-left:203px;" 
ng-click="nextDetail()">
</div>

JS Code(in your controller):

$scope.nextDetail = function()
{
....
}

What Harry S says is exactly right, but

int? accom = (accomStr == "noval" ? null : (int?)Convert.ToInt32(accomStr));

would also do the trick. (We Resharper users can always spot each other in crowds...)

run(s) of digits

This answer works with any count of digit groups. Example:

$ echo 'Num123that456are7899900contained0018166intext' \
   | sed -En 's/[^0-9]*([0-9]{1,})[^0-9]*/\1 /gp'

123 456 7899900 0018166

Expanded answer.

Is there any way to tell sed to output only captured groups?

Yes. replace all text by the capture group:

$ echo 'Number 123 inside text' \
   | sed 's/[^0-9]*\([0-9]\{1,\}\)[^0-9]*/\1/'

123

s/[^0-9]*                           # several non-digits
         \([0-9]\{1,\}\)            # followed by one or more digits
                        [^0-9]*     # and followed by more non-digits.
                               /\1/ # gets replaced only by the digits.

Or with extended syntax (less backquotes and allow the use of +):

$ echo 'Number 123 in text' \
   | sed -E 's/[^0-9]*([0-9]+)[^0-9]*/\1/'

123

To avoid printing the original text when there is no number, use:

$ echo 'Number xxx in text' \
   | sed -En 's/[^0-9]*([0-9]+)[^0-9]*/\1/p'

• (-n) Do not print the input by default.
• (/p) print only if a replacement was done.

And to match several numbers (and also print them):

$ echo 'N 123 in 456 text' \
  | sed -En 's/[^0-9]*([0-9]+)[^0-9]*/\1 /gp'

123 456

That works for any count of digit runs:

$ str='Test Num(s) 123 456 7899900 contained as0018166df in text'
$ echo "$str" \
   | sed -En 's/[^0-9]*([0-9]{1,})[^0-9]*/\1 /gp'

123 456 7899900 0018166

Which is very similar to the grep command:

$ str='Test Num(s) 123 456 7899900 contained as0018166df in text'
$ echo "$str" | grep -Po '\d+'
123
456
7899900
0018166

About \d

and pattern: /([\d]+)/

Sed does not recognize the '\d' (shortcut) syntax. The ascii equivalent used above [0-9] is not exactly equivalent. The only alternative solution is to use a character class: '[[:digit:]]`.

The selected answer use such "character classes" to build a solution:

$ str='This is a sample 123 text and some 987 numbers'
$ echo "$str" | sed -rn 's/[^[:digit:]]*([[:digit:]]+)[^[:digit:]]+([[:digit:]]+)[^[:digit:]]*/\1 \2/p'

That solution only works for (exactly) two runs of digits.

Of course, as the answer is being executed inside the shell, we can define a couple of variables to make such answer shorter:

$ str='This is a sample 123 text and some 987 numbers'
$ d=[[:digit:]]     D=[^[:digit:]]
$ echo "$str" | sed -rn "s/$D*($d+)$D+($d+)$D*/\1 \2/p"

But, as has been already explained, using a s/…/…/gp command is better:

$ str='This is 75577 a sam33ple 123 text and some 987 numbers'
$ d=[[:digit:]]     D=[^[:digit:]]
$ echo "$str" | sed -rn "s/$D*($d+)$D*/\1 /gp"
75577 33 123 987

That will cover both repeated runs of digits and writing a short(er) command.

Here's a snippet of how to get the creation time of files in the directory and find those which have been created 3 months ago (90 days ago to be exact):

    DirectoryInfo source = new DirectoryInfo(sourceDirectoryPath);

    // Get info of each file into the directory
    foreach (FileInfo fi in source.GetFiles())
    {
        var creationTime = fi.CreationTime;

        if(creationTime < (DateTime.Now- new TimeSpan(90, 0, 0, 0)))
        {
            fi.Delete();
        }
    }

The shortest solution without any dependencies:

await new Promise(resolve => setTimeout(resolve, 5000));

You can use SQL Management Objects to perform this. These are the same objects that Management Studio uses to execute queries. I believe Server.ConnectionContext.ExecuteNonQuery() will perform what you need.

 var text = File.ReadAllText(file, Encoding.GetEncoding(codePage));

List of codepages : http://msdn.microsoft.com/en-us/library/windows/desktop/dd317756(v=vs.85).aspx

you can edit all the columns at once by using this simple code via Foreach loop

        foreach (DataGridViewColumn item in datagridview1.Columns)
        {
            item.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;
        }

XAMPP for linux and mac comes with ProFTPD. Make sure to start the service from XAMPP control panel -> manage servers.

Further complete instructions can be found at localhost XAMPP dashboard -> How-to guides -> Configure FTP Access. I have pasted them below :

1. Open a new Linux terminal and ensure you are logged in as root.

2. Create a new group named ftp. This group will contain those user accounts allowed to upload files via FTP.

groupadd ftp

3. Add your account (in this example, susan) to the new group. Add other users if needed.

usermod -a -G ftp susan

4. Change the ownership and permissions of the htdocs/ subdirectory of the XAMPP installation directory (typically, /opt/lampp) so that it is writable by the the new ftp group.

cd /opt/lampp chown root.ftp htdocs chmod 775 htdocs

5. Ensure that proFTPD is running in the XAMPP control panel.

You can now transfer files to the XAMPP server using the steps below:

1. Start an FTP client like winSCP or FileZilla and enter connection details as below.

If you’re connecting to the server from the same system, use "127.0.0.1" as the host address. If you’re connecting from a different system, use the network hostname or IP address of the XAMPP server.

Use "21" as the port.

Enter your Linux username and password as your FTP credentials.

Your FTP client should now connect to the server and enter the /opt/lampp/htdocs/ directory, which is the default Web server document root.

2. Transfer the file from your home directory to the server using normal FTP transfer conventions. If you’re using a graphical FTP client, you can usually drag and drop the file from one directory to the other. If you’re using a command-line FTP client, you can use the FTP PUT command.

Once the file is successfully transferred, you should be able to see it in action.

Shell.Application

With Shell.Application you can emulate the way explorer.exe zips files and folders The script is called zipjs.bat:

call zipjs.bat unzip -source C:\myDir\myZip.zip -destination C:\MyDir -keep no -force no

call zipjs.bat list -source C:\myZip.zip\inZipDir -flat yes

:: lists content of a zip file and the content will be list as a tree (-flat no)
call zipjs.bat list -source C:\myZip.zip -flat no

:: prints uncompressed size in bytes
zipjs.bat getSize -source C:\myZip.zip

:: zips content of folder without the folder itself
call zipjs.bat zipDirItems -source C:\myDir\ -destination C:\MyZip.zip -keep yes -force no

:: zips file or a folder (with the folder itslelf)
call zipjs.bat zipItem -source C:\myDir\myFile.txt -destination C:\MyZip.zip -keep yes -force no

MAKECAB

Makecab is the default compressing tool coming with windows. Though it can use different compression algorithms (including zip) file format is always a .cab file. With some extensions it can be used on linux machines too.

compressing a file:

makecab file.txt "file.cab"

Compressing an entire folder needs a little bit more work. Here a directory is compressed with cabDir.bat:

call cabDir.bat ./myDir compressedDir.cab

Uncompressing is rather easy with expand command:

EXPAND cabfile -F:* .

More hackier way is by creating self-extracting executable with extrac32 command:

copy /b "%windir%\system32\extrac32.exe"+"mycab.cab" "expandable.exe"
call expandable.exe

TAR

With the build 17063 of windows we have the tar command:

::compress directory
tar -cvf archive.tar c:\my_dir
::extract to dir
tar -xvf archive.tar.gz -C c:\data

.NET tools

.net (and powershell) offers a lot of ways to compress and uncompress files. The most straightforward is with gzip stream. The script is called gzipjs.bat:

::zip
call gzipjs.bat -c my.file my.zip
::unzip
call gzipjs.bat -u my.zip my.file

The solution to the problem is that in your CREATE TABLE statement, you may add the constraint UNIQUE ( problemtextfield(300) ) after the column create definitions to specify a key length of 300 characters for a TEXT field, for example. Then the first 300 characters of the problemtextfield TEXT field would need to be unique, and any differences after that would be disregarded.

os.path.split(os.path.realpath(__file__))[0]

os.path.realpath(__file__)return the abspath of the current script; os.path.split(abspath)[0] return the current dir

Queue is an interface; you can't explicitly construct a Queue. You'll have to instantiate one of its implementing classes. Something like:

Queue linkedList = new LinkedList();

Using the multicol package and embedding your list in a multicols environment does what you want:

\documentclass{article}
\usepackage{multicol}

\begin{document}
\begin{multicols}{2}
\begin{enumerate}
    \item a
    \item b
    \item c
    \item d
    \item e
    \item f
\end{enumerate}
\end{multicols}
\end{document}

The align attribute is deprecated. Use CSS text-align instead. Also, the span will not center the text unless you use display:block or display:inline-block and set a value for the width, but then it will behave the same as a div (block element).

Can you post an example of your layout? Use www.jsfiddle.net

This is the dumbest answer to this question, but check the status of GitHub. This one got me :)

If it's not working from web.config, you need to set it from IIS.

In a recent project I changed the default activity in AndroidManifest.xml with:

<activity android:name=".MyAppRuntimePermissions">
</activity>

<activity android:name=".MyAppDisplay">
    <intent-filter>
        <action android:name="android.intent.activity.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

In Android Studio 3.6; this seems to broken. I've used this technique in example applications, but when I use it in this real-world application it falls flat. The IDE once again reports:

Error running app: Default activity not found.

The IDE still showed a configuration error in the "run app" space in the toolbar (yellow arrow in this screenshot)

To correct this error I've tried several rebuilds of the project, and finally File >> "Invalidate Cache/Restart". This did not help. To run the application I had to "Edit Configurations" and point at the specific activity instead of the default activity:

Doesn't have to be; "64-bit machine" can mean many things, but typically means that the CPU has registers that big. The sizeof a type is determined by the compiler, which doesn't have to have anything to do with the actual hardware (though it typically does); in fact, different compilers on the same machine can have different values for these.

To replace the old version with the new one, you need to change the link for it. Type that command to terminal.

brew link --force openssl

Check the version of openssl again. It should be changed.

I suggest that you should not do it like this. Action methods should be designed to be easily unit-tested. In this case, you should not access data directly from the request, because if you do it like this, when you want to unit test this code you have to construct a HttpRequestMessage.

You should do it like this to let MVC do all the model binding for you:

[HttpPost]
public void Confirmation(YOURDTO yourobj)//assume that you define YOURDTO elsewhere
{
        //your logic to process input parameters.

}

In case you do want to access the request. You just access the Request property of the controller (not through parameters). Like this:

[HttpPost]
public void Confirmation()
{
    var content = Request.Content.ReadAsStringAsync().Result;
}

In MVC, the Request property is actually a wrapper around .NET HttpRequest and inherit from a base class. When you need to unit test, you could also mock this object.

A Transaction represents a unit of work with a database.

In spring TransactionDefinition interface that defines Spring-compliant transaction properties. @Transactional annotation describes transaction attributes on a method or class.

@Autowired
private TestDAO testDAO;

@Transactional(propagation=TransactionDefinition.PROPAGATION_REQUIRED,isolation=TransactionDefinition.ISOLATION_READ_UNCOMMITTED)
public void someTransactionalMethod(User user) {

  // Interact with testDAO

}

Propagation (Reproduction) : is uses for inter transaction relation. (analogous to java inter thread communication)

+-------+---------------------------+------------------------------------------------------------------------------------------------------+
| value |        Propagation        |                                             Description                                              |

Isolation : Isolation is one of the ACID (Atomicity, Consistency, Isolation, Durability) properties of database transactions. Isolation determines how transaction integrity is visible to other users and systems. It uses for resource locking i.e. concurrency control, make sure that only one transaction can access the resource at a given point.

Locking perception: isolation level determines the duration that locks are held.

+---------------------------+-------------------+-------------+-------------+------------------------+
| Isolation Level Mode      |  Read             |   Insert    |   Update    |       Lock Scope       |
+---------------------------+-------------------+-------------+-------------+------------------------+
| READ_UNCOMMITTED          |  uncommitted data | Allowed     | Allowed     | No Lock                |
| READ_COMMITTED (Default)  |   committed data  | Allowed     | Allowed     | Lock on Committed data |
| REPEATABLE_READ           |   committed data  | Allowed     | Not Allowed | Lock on block of table |
| SERIALIZABLE              |   committed data  | Not Allowed | Not Allowed | Lock on full table     |
+---------------------------+-------------------+-------------+-------------+------------------------+

Read perception: the following 3 kinds of major problems occurs:

• Dirty reads : reads uncommitted data from another tx(transaction).
• Non-repeatable reads : reads committed UPDATES from another tx.
• Phantom reads : reads committed INSERTS and/or DELETES from another tx

Isolation levels with different kinds of reads:

+---------------------------+----------------+----------------------+----------------+
| Isolation Level Mode      |  Dirty reads   | Non-repeatable reads | Phantoms reads |
+---------------------------+----------------+----------------------+----------------+
| READ_UNCOMMITTED          | allows         | allows               | allows         |
| READ_COMMITTED (Default)  | prevents       | allows               | allows         |
| REPEATABLE_READ           | prevents       | prevents             | allows         |
| SERIALIZABLE              | prevents       | prevents             | prevents       |

for examples

No such file or directory can be also raised if you are trying to put a file argument to Popen with double-quotes.

For example:

call_args = ['mv', '"path/to/file with spaces.txt"', 'somewhere']

In this case, you need to remove double-quotes.

call_args = ['mv', 'path/to/file with spaces.txt', 'somewhere']

C:\Users\\Anaconda3

I just added above path , to my path environment variables and it worked. Now, all we have to do is to move to the .py script location directory, open the cmd with that location and run to see the output.

An example might have been useful, but if I understood you correctly, this would work:

echo "Hello: world" | cut -f1 -d":"

This will convert Hello: world into Hello.

"Unable to load the requested file"

Can be also caused by access permissions under linux , make sure you set the correct read permissions for the directory "views/home"

If you are using a data source, here's another way to do it without code behind.

Note the following key points:

• The ListItem of Value="0" is on the source page, not added in code
• The ListItem in the source will be overwritten if you don't include AppendDataBoundItems="true" in the DropDownList
• InitialValue="0" tells the validator that this is the value that should fire that validator (as pointed out in other answers)

Example:

<asp:DropDownList ID="ddlType" runat="server" DataSourceID="sdsType"
                  DataValueField="ID" DataTextField="Name" AppendDataBoundItems="true">
    <asp:ListItem Value="0" Text="--Please Select--" Selected="True"></asp:ListItem>
</asp:DropDownList>
<asp:RequiredFieldValidator ID="rfvType" runat="server" ControlToValidate="ddlType" 
                            InitialValue="0" ErrorMessage="Type required"></asp:RequiredFieldValidator>
<asp:SqlDataSource ID="sdsType" runat="server" 
                   ConnectionString='<%$ ConnectionStrings:TESTConnectionString %>'
                   SelectCommand="SELECT ID, Name FROM Type"></asp:SqlDataSource>

ravel() and flatten() functions from numpy are two techniques that I would try here. I will like to add to the posts made by Joe, Siraj, bubble and Kevad.

Ravel:

A = M.ravel()
print A, A.shape
>>> [1 2 3 4] (4,)

Flatten:

M = np.array([[1], [2], [3], [4]])
A = M.flatten()
print A, A.shape
>>> [1 2 3 4] (4,)

numpy.ravel() is faster, since it is a library level function which does not make any copy of the array. However, any change in array A will carry itself over to the original array M if you are using numpy.ravel().

numpy.flatten() is slower than numpy.ravel(). But if you are using numpy.flatten() to create A, then changes in A will not get carried over to the original array M.

numpy.squeeze() and M.reshape(-1) are slower than numpy.flatten() and numpy.ravel().

%timeit M.ravel()
>>> 1000000 loops, best of 3: 309 ns per loop

%timeit M.flatten()
>>> 1000000 loops, best of 3: 650 ns per loop

%timeit M.reshape(-1)
>>> 1000000 loops, best of 3: 755 ns per loop

%timeit np.squeeze(M)
>>> 1000000 loops, best of 3: 886 ns per loop

Also , with Anonymous types ( I prefer not to do this) -- this is just another approach.

void Main()
{
    var x = new
    {
        items = new[]
        {
            new
            {
                name = "command", index = "X", optional = "0"
            },
            new
            {
                name = "command", index = "X", optional = "0"
            }
        }
    };
    JavaScriptSerializer js = new JavaScriptSerializer(); //system.web.extension assembly....
    Console.WriteLine(js.Serialize(x));
}

result :

{"items":[{"name":"command","index":"X","optional":"0"},{"name":"command","index":"X","optional":"0"}]}

My Swift 5 implementation is to set the hight constraint of the tableView to the size of its content (contentSize.height). This method assumes you are using auto layout. This code should be placed inside the cellForRowAt tableView method.

tableView.heightAnchor.constraint(equalToConstant: tableView.contentSize.height).isActive = true

we can emulate a private property of a class using getter and setter.

eg 1

class FootballClub {
    constructor (cname, cstadium, ccurrentmanager) {
        this.name = cname;
        this._stadium  = cstadium;  //  we will treat this prop as private and give getter and setter for this.
        this.currmanager = ccurrentmanager;
    }

    get stadium( ) {
        return this._stadium.toUpperCase();
    }

}

let club = new FootballClub("Arsenal", "Emirates" , "Arteta")
console.log(club);
//FootballClub {
//    name: 'Arsenal',
//    _stadium: 'Emirates',
//    currmanager: 'Arteta'
//  }
console.log( club.stadium ); // EMIRATES
club.stadium = "Highbury"; // TypeError: Cannot set property stadium of #<FootballClub> which has only a getter

In the above example we have not given a setter method for stadium and thus we are not able to set a new value for this. In the next eg a setter is added for stadium

eg 2

class FootballClub {
    constructor (cname, cstadium, ccurrentmanager) {
        this.name = cname;
        this._stadium  = cstadium;  //  we will treat this prop as private and give getter and setter for this.
        this.currmanager = ccurrentmanager;
    }

    get stadium( ) {
        return this._stadium.toUpperCase();
    }

    set stadium(val) {
       this._stadium = val;
    }
}

let club = new FootballClub("Arsenal", "Emirates" , "Arteta")
console.log(club.stadium); // EMIRATES
club.stadium = "Emirates Stadium";
console.log(club.stadium); // EMIRATES STADIUM

There's an excellent presentation by Raymond Hettinger, titled Transforming Code into Beautiful, Idiomatic Python, in which he briefly addresses the history of the for ... else construct. The relevant section is "Distinguishing multiple exit points in loops" starting at 15:50 and continuing for about three minutes. Here are the high points:

• The for ... else construct was devised by Donald Knuth as a replacement for certain GOTO use cases;
• Reusing the else keyword made sense because "it's what Knuth used, and people knew, at that time, all [for statements] had embedded an if and GOTO underneath, and they expected the else;"
• In hindsight, it should have been called "no break" (or possibly "nobreak"), and then it wouldn't be confusing.*

So, if the question is, "Why don't they change this keyword?" then Cat Plus Plus probably gave the most accurate answer – at this point, it would be too destructive to existing code to be practical. But if the question you're really asking is why else was reused in the first place, well, apparently it seemed like a good idea at the time.

Personally, I like the compromise of commenting # no break in-line wherever the else could be mistaken, at a glance, as belonging inside the loop. It's reasonably clear and concise. This option gets a brief mention in the summary that Bjorn linked at the end of his answer:

For completeness, I should mention that with a slight change in syntax, programmers who want this syntax can have it right now:

for item in sequence:
    process(item)
else:  # no break
    suite

_{* Bonus quote from that part of the video: "Just like if we called lambda makefunction, nobody would ask, 'What does lambda do?'"}

How about

a["abc"] = [1, 2]

This will result in:

>>> a
{'abc': [1, 2]}

Is that what you were looking for?

If you just want to show label below the marker, then you can extend google maps Marker to add a setter method for label and you can define the label object by extending google maps overlayView like this..

<script type="text/javascript">
    var point = { lat: 22.5667, lng: 88.3667 };
    var markerSize = { x: 22, y: 40 };


    google.maps.Marker.prototype.setLabel = function(label){
        this.label = new MarkerLabel({
          map: this.map,
          marker: this,
          text: label
        });
        this.label.bindTo('position', this, 'position');
    };

    var MarkerLabel = function(options) {
        this.setValues(options);
        this.span = document.createElement('span');
        this.span.className = 'map-marker-label';
    };

    MarkerLabel.prototype = $.extend(new google.maps.OverlayView(), {
        onAdd: function() {
            this.getPanes().overlayImage.appendChild(this.span);
            var self = this;
            this.listeners = [
            google.maps.event.addListener(this, 'position_changed', function() { self.draw();    })];
        },
        draw: function() {
            var text = String(this.get('text'));
            var position = this.getProjection().fromLatLngToDivPixel(this.get('position'));
            this.span.innerHTML = text;
            this.span.style.left = (position.x - (markerSize.x / 2)) - (text.length * 3) + 10 + 'px';
            this.span.style.top = (position.y - markerSize.y + 40) + 'px';
        }
    });
    function initialize(){
        var myLatLng = new google.maps.LatLng(point.lat, point.lng);
        var gmap = new google.maps.Map(document.getElementById('map_canvas'), {
            zoom: 5,
            center: myLatLng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        });
        var myMarker = new google.maps.Marker({
            map: gmap,
            position: myLatLng,
            label: 'Hello World!',
            draggable: true
        });
    }
</script>
<style>
    .map-marker-label{
        position: absolute;
    color: blue;
    font-size: 16px;
    font-weight: bold;
    }
</style>

This will work.

If the python version is 3.X, it's okay.

I think your python version is 2.X, the super would work when adding this code

__metaclass__ = type

so the code is

__metaclass__ = type
class B:
    def meth(self, arg):
        print arg
class C(B):
    def meth(self, arg):
        super(C, self).meth(arg)
print C().meth(1)

This is not a PowerShell-specific answer, but you could authenticate against the share using "NET USE" first:

And then do whatever you need to do in PowerShell...

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '<

I am trying to parse JSON data returned from an ajax call, and the following is working for me:

Sample PHP code

$portfolio_array= Array('desc'=>'This is test description1','item1'=>'1.jpg','item2'=>'2.jpg');

echo json_encode($portfolio_array);

And in the .js, i am parsing like this:

var req=$.post("json.php", { id: "" + id + ""},
function(data) {
    data=$.parseJSON(data);
    alert(data.desc);
    $.each(data, function(i,item){
    alert(item);
    });
})
.success(function(){})
.error(function(){alert('There was problem loading portfolio details.');})
.complete(function(){});

If you have multidimensional array like below

$portfolio_array= Array('desc'=>'This is test description 1','items'=> array('item1'=>'1.jpg','item2'=>'2.jpg'));
echo json_encode($portfolio_array);

Then the code below should work:

var req=$.post("json.php", { id: "" + id + 
    function(data) {
    data=$.parseJSON(data);
    alert(data.desc);
    $.each(data.items, function(i,item){
    alert(item);
    });
})
.success(function(){})
.error(function(){alert('There was problem loading portfolio details.');})
.complete(function(){});

Please note the sub array key here is items, and suppose if you have xyz then in place of data.items use data.xyz

Because a dictionary is a single value. You need to use keyword expansion if you want to pass it as a group of keyword arguments.

You should be careful when implementing two-factor auth, you need to ensure your clocks on the server and client are synchronized, that there is protection in place against brute-force attacks on the token and that the initial seed used is suitably large.

I would recommend OAuth 2/3. You can find more information at http://oauth.net/2/

The parent probably isn't yet set when you are trying to access it.

Try this:

loginForm = new SubLogin();
loginForm.Show(this);
loginForm.CenterToParent()

These three dots are called spread operator. Spread operator helps us to create a copy state or props in react.

Using spread operator in react state

const [myState, setMyState] = useState({
    variable1: 'test',
    variable2: '',
    variable3: ''
});

setMyState({...myState, variable2: 'new value here'});

in the above code spread operator will maintain a copy of current state and we will also add new value at same time, if we don't do this then state will have only value of variable2 spread operator helps us to write optimize code

This solution may help.

An additional tip for SolidSmile's cheat is to scale (the proportionate re-sizing) by setting a width and using auto for height.

Ex:

#background {
    width: 500px;
    height: auto;
    position: absolute; 
    left: 0px; 
    top: 0px; 
    z-index: 0;
}

A TVF (table-valued function) is supposed to be SELECTed FROM. Try this:

select * from FN('myFunc')

You could just use list comprehension:

property_asel = [val for is_good, val in zip(good_objects, property_a) if is_good]

or

property_asel = [property_a[i] for i in good_indices]

The latter one is faster because there are fewer good_indices than the length of property_a, assuming good_indices are precomputed instead of generated on-the-fly.

Edit: The first option is equivalent to itertools.compress available since Python 2.7/3.1. See @Gary Kerr's answer.

property_asel = list(itertools.compress(property_a, good_objects))

In simple way you can go with explode($delimiter, $string);

But in a broad way, with Manual Programming :

        $string = "ab,cdefg,xyx,ht623";
        $resultArr = [];
        $strLength = strlen($string);
        $delimiter = ',';
        $j = 0;
        $tmp = '';
        for ($i = 0; $i < $strLength; $i++) {
            if($delimiter === $string[$i]) {
                $j++;
                $tmp = '';
                continue;
            }
            $tmp .= $string[$i];
            $resultArr[$j] = $tmp;
        }

Outpou : print_r($resultArr);

Array
(
    [0] => ab
    [1] => cdefg
    [2] => xyx
    [3] => ht623
)

You are calling:

JSON.parse(scatterSeries)

But when you defined scatterSeries, you said:

var scatterSeries = []; 

When you try to parse it as JSON it is converted to a string (""), which is empty, so you reach the end of the string before having any of the possible content of a JSON text.

scatterSeries is not JSON. Do not try to parse it as JSON.

data is not JSON either (getJSON will parse it as JSON automatically).

ch is JSON … but shouldn't be. You should just create a plain object in the first place:

var ch = {
    "name": "graphe1",
    "items": data.results[1]
};

scatterSeries.push(ch);

In short, for what you are doing, you shouldn't have JSON.parse anywhere in your code. The only place it should be is in the jQuery library itself.

Internet Explorer 9 and lower : You could use conditional comments to load an IE-specific stylesheet for any version (or combination of versions) that you wanted to specifically target.like below using external stylesheet.

<!--[if IE]>
  <link rel="stylesheet" type="text/css" href="all-ie-only.css" />
<![endif]-->

However, beginning in version 10, conditional comments are no longer supported in IE.

Internet Explorer 10 & 11 : Create a media query using -ms-high-contrast, in which you place your IE 10 and 11-specific CSS styles. Because -ms-high-contrast is Microsoft-specific (and only available in IE 10+), it will only be parsed in Internet Explorer 10 and greater.

@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
     /* IE10+ CSS styles go here */
}

Microsoft Edge 12 : Can use the @supports rule Here is a link with all the info about this rule

@supports (-ms-accelerator:true) {
  /* IE Edge 12+ CSS styles go here */ 
}

Inline rule IE8 detection

I have 1 more option but it is only detect IE8 and below version.

  /* For IE css hack */
  margin-top: 10px\9 /* apply to all ie from 8 and below */
  *margin-top:10px;  /* apply to ie 7 and below */
  _margin-top:10px; /* apply to ie 6 and below */

As you specefied for embeded stylesheet. I think you need to use media query and condition comment for below version.

Most of the answers have mentioned http://checkip.dyndns.org in solution. For us, it didn't worked out well. We have faced Timemouts a lot of time. Its really troubling if your program is dependent on the IP detection.

As a solution, we use the following method in one of our desktop applications:

    // Returns external/public ip
    protected string GetExternalIP()
    {
        try
        {
            using (MyWebClient client = new MyWebClient())
            {
                client.Headers["User-Agent"] =
                "Mozilla/4.0 (Compatible; Windows NT 5.1; MSIE 6.0) " +
                "(compatible; MSIE 6.0; Windows NT 5.1; " +
                ".NET CLR 1.1.4322; .NET CLR 2.0.50727)";

                try
                {
                    byte[] arr = client.DownloadData("http://checkip.amazonaws.com/");

                    string response = System.Text.Encoding.UTF8.GetString(arr);

                    return response.Trim();
                }
                catch (WebException ex)
                {
                    // Reproduce timeout: http://checkip.amazonaws.com:81/

                    // trying with another site
                    try
                    {
                        byte[] arr = client.DownloadData("http://icanhazip.com/");

                        string response = System.Text.Encoding.UTF8.GetString(arr);

                        return response.Trim();
                    }
                    catch (WebException exc)
                    { return "Undefined"; }
                }
            }
        }
        catch (Exception ex)
        {
            // TODO: Log trace
            return "Undefined";
        }
    }

Good part is, both sites return IP in plain format. So string operations are avoided.

To check your logic in catch clause, you can reproduce Timeout by hitting a non available port. eg: http://checkip.amazonaws.com:81/

Use all() method - it's designed to return items of Collection:

/**
 * Get all of the items in the collection.
 *
 * @return array
 */
public function all()
{
    return $this->items;
}

Your calculation is correct for DATE types, but if your values are timestamps, you should probably use EXTRACT (or DATE_PART) to be sure to get only the difference in full days;

EXTRACT(DAY FROM MAX(joindate)-MIN(joindate)) AS DateDifference

An SQLfiddle to test with. Note the timestamp difference being 1 second less than 2 full days.

You can use defaultdict in collections.

An example from doc:

s = [('yellow', 1), ('blue', 2), ('yellow', 3), ('blue', 4), ('red', 1)]
d = defaultdict(list)
for k, v in s:
    d[k].append(v)

If you are using unix, you need to write a shellscript to run you java batch first.

After that, in unix, you run this command "crontab -e" to edit crontab script. In order to configure crontab, please refer to this article http://www.thegeekstuff.com/2009/06/15-practical-crontab-examples/

Save your crontab setting. Then wait for the time to come, program will run automatically.

Some Bash tricks I use to set variables from commands

Sorry, there is a loong answer, but as bash is a shell, where the main goal is to run other unix commands and react to resut code and/or output, ( commands are often piped filter, etc... ).

Storing command output in variables is something basic and fundamental.

Therefore, depending on

• compatibility (posix)
• kind of output (filter(s))
• number of variable to set (split or interpret)
• execution time (monitoring)
• error trapping
• repeatability of request (see long running background process, further)
• interactivity (considering user input while reading from another input file descriptor)
• do I miss something?

First simple, old, and compatible way

myPi=`echo '4*a(1)' | bc -l`
echo $myPi 
3.14159265358979323844

Mostly compatible, second way

As nesting could become heavy, parenthesis was implemented for this

myPi=$(bc -l <<<'4*a(1)')

Nested sample:

SysStarted=$(date -d "$(ps ho lstart 1)" +%s)
echo $SysStarted 
1480656334

bash features

Reading more than one variable (with Bashisms)

df -k /
Filesystem     1K-blocks   Used Available Use% Mounted on
/dev/dm-0         999320 529020    401488  57% /

If I just want a used value:

array=($(df -k /))

you could see an array variable:

declare -p array
declare -a array='([0]="Filesystem" [1]="1K-blocks" [2]="Used" [3]="Available" [
4]="Use%" [5]="Mounted" [6]="on" [7]="/dev/dm-0" [8]="999320" [9]="529020" [10]=
"401488" [11]="57%" [12]="/")'

Then:

echo ${array[9]}
529020

But I often use this:

{ read foo ; read filesystem size using avail prct mountpoint ; } < <(df -k /)
echo $using
529020

The first read foo will just skip header line, but in only one command, you will populate 7 different variables:

declare -p avail filesystem foo mountpoint prct size using
declare -- avail="401488"
declare -- filesystem="/dev/dm-0"
declare -- foo="Filesystem     1K-blocks   Used Available Use% Mounted on"
declare -- mountpoint="/"
declare -- prct="57%"
declare -- size="999320"
declare -- using="529020"

Or

{ read -a head;varnames=(${head[@]//[K1% -]});varnames=(${head[@]//[K1% -]});
  read ${varnames[@],,} ; } < <(LANG=C df -k /)

Then:

declare -p varnames ${varnames[@],,} 
declare -a varnames=([0]="Filesystem" [1]="blocks" [2]="Used" [3]="Available" [4]="Use" [5]="Mounted" [6]="on")
declare -- filesystem="/dev/dm-0"
declare -- blocks="999320"
declare -- used="529020"
declare -- available="401488"
declare -- use="57%"
declare -- mounted="/"
declare -- on=""

Or even:

{ read foo ; read filesystem dsk[{6,2,9}] prct mountpoint ; } < <(df -k /)
declare -p mountpoint dsk
declare -- mountpoint="/"
declare -a dsk=([2]="529020" [6]="999320" [9]="401488")

(Note Used and Blocks is switched there: read ... dsk[6] dsk[2] dsk[9] ...)

... will work with associative arrays too: read foo disk[total] disk[used] ...

Dedicated fd using unnamed fifo:

There is an elegent way:

users=()
while IFS=: read -u $list user pass uid gid name home bin ;do
    ((uid>=500)) &&
        printf -v users[uid] "%11d %7d %-20s %s\n" $uid $gid $user $home
done {list}</etc/passwd

Using this way (... read -u $list; ... {list}<inputfile) leave STDIN free for other purposes, like user interaction.

Then

echo -n "${users[@]}"
       1000    1000 user         /home/user
...
      65534   65534 nobody       /nonexistent

and

echo ${!users[@]}
1000 ... 65534

echo -n "${users[1000]}"
      1000    1000 user       /home/user

This could be used with static files or even /dev/tcp/xx.xx.xx.xx/yyy with x for ip address or hostname and y for port number:

{
    read -u $list -a head          # read header in array `head`
    varnames=(${head[@]//[K1% -]}) # drop illegal chars for variable names
    while read -u $list ${varnames[@],,} ;do
        ((pct=available*100/(available+used),pct<10)) &&
            printf "WARN: FS: %-20s on %-14s %3d <10 (Total: %11u, Use: %7s)\n" \
                "${filesystem#*/mapper/}" "$mounted" $pct $blocks "$use"
     done
 } {list}< <(LANG=C df -k)

And of course with inline documents:

while IFS=\; read -u $list -a myvar ;do
    echo ${myvar[2]}
done {list}<<"eof"
foo;bar;baz
alice;bob;charlie
$cherry;$strawberry;$memberberries
eof

Sample function for populating some variables:

#!/bin/bash

declare free=0 total=0 used=0

getDiskStat() {
    local foo
    {
        read foo
        read foo total used free foo
    } < <(
        df -k ${1:-/}
    )
}

getDiskStat $1
echo $total $used $free

Nota: declare line is not required, just for readability.

About sudo cmd | grep ... | cut ...

shell=$(cat /etc/passwd | grep $USER | cut -d : -f 7)
echo $shell
/bin/bash

(Please avoid useless cat! So this is just one fork less:

shell=$(grep $USER </etc/passwd | cut -d : -f 7)

All pipes (|) implies forks. Where another process have to be run, accessing disk, libraries calls and so on.

So using sed for sample, will limit subprocess to only one fork:

shell=$(sed </etc/passwd "s/^$USER:.*://p;d")
echo $shell

And with Bashisms:

But for many actions, mostly on small files, Bash could do the job itself:

while IFS=: read -a line ; do
    [ "$line" = "$USER" ] && shell=${line[6]}
  done </etc/passwd
echo $shell
/bin/bash

or

while IFS=: read loginname encpass uid gid fullname home shell;do
    [ "$loginname" = "$USER" ] && break
  done </etc/passwd
echo $shell $loginname ...

Going further about variable splitting...

Have a look at my answer to How do I split a string on a delimiter in Bash?

Alternative: reducing forks by using backgrounded long-running tasks

In order to prevent multiple forks like

myPi=$(bc -l <<<'4*a(1)'
myRay=12
myCirc=$(bc -l <<<" 2 * $myPi * $myRay ")

or

myStarted=$(date -d "$(ps ho lstart 1)" +%s)
mySessStart=$(date -d "$(ps ho lstart $$)" +%s)

This work fine, but running many forks is heavy and slow.

And commands like date and bc could make many operations, line by line!!

See:

bc -l <<<$'3*4\n5*6'
12
30

date -f - +%s < <(ps ho lstart 1 $$)
1516030449
1517853288

So we could use a long running background process to make many jobs, without having to initiate a new fork for each request.

Under bash, there is a built-in function: coproc:

coproc bc -l
echo 4*3 >&${COPROC[1]}
read -u $COPROC answer
echo $answer
12

echo >&${COPROC[1]} 'pi=4*a(1)'
ray=42.0
printf >&${COPROC[1]} '2*pi*%s\n' $ray
read -u $COPROC answer
echo $answer
263.89378290154263202896

printf >&${COPROC[1]} 'pi*%s^2\n' $ray
read -u $COPROC answer
echo $answer
5541.76944093239527260816

As bc is ready, running in background and I/O are ready too, there is no delay, nothing to load, open, close, before or after operation. Only the operation himself! This become a lot quicker than having to fork to bc for each operation!

Border effect: While bc stay running, they will hold all registers, so some variables or functions could be defined at initialisation step, as first write to ${COPROC[1]}, just after starting the task (via coproc).

The function myBc lets you use the background task with simple syntax, and for date:

newConnector /bin/date '-f - +%s' @0 0
myDate '2000-01-01'
  946681200
myDate "$(ps ho lstart 1)" boottime
myDate now now ; read utm idl </proc/uptime
myBc "$now-$boottime" uptime

   3162 pts/20   R+     0:00  \_ ps --tty pts/20 fw

From there, if you want to end one of background processes, you just have to close its fd:

eval "exec $DATEOUT>&-"
eval "exec $DATEIN>&-"
ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
   4936 pts/20   Ss     0:00 bash
   5256 pts/20   S      0:00  \_ /usr/bin/bc -l
   6358 pts/20   R+     0:00  \_ ps --tty pts/20 fw

which is not needed, because all fd close when the main process finishes.

As everyone else said, but remember CultureInfo.InvariantCulture!

string s = dt.ToString("dd/M/yyyy", CultureInfo.InvariantCulture)

OR escape the '/'.

It is not guaranteed that the slicing returns a view or a copy. You can do

df['column'] = df['column'].fillna(value)

I like to make use of the css :before and a data-* attribute for the list

HTML:

<ul data-header="heading"> 
<li>list item </li>
<li>list item </li>
<li>list item </li>
</ul>

CSS:

ul:before{
    content:attr(data-header);
    font-size:120%;
    font-weight:bold;
    margin-left:-15px;
}

This will make a list with the header on it that is whatever text is specified as the list's data-header attribute. You can then easily style it to your needs.

I. Plain XSLT 1.0 solution:

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()" name="split">
  <xsl:param name="pText" select="."/>
  <xsl:if test="string-length($pText)">
   <xsl:if test="not($pText=.)">
    <br />
   </xsl:if>
   <xsl:value-of select=
    "substring-before(concat($pText,';'),';')"/>
   <xsl:call-template name="split">
    <xsl:with-param name="pText" select=
     "substring-after($pText, ';')"/>
   </xsl:call-template>
  </xsl:if>
 </xsl:template>
</xsl:stylesheet>

when applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

produces the wanted, corrected result:

123 Elm Street<br />PO Box 222<br />c/o James Jones

II. FXSL 1 (for XSLT 1.0):

Here we just use the FXSL template str-map (and do not have to write recursive template for the 999th time):

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:f="http://fxsl.sf.net/"
xmlns:testmap="testmap"
exclude-result-prefixes="xsl f testmap"
>
   <xsl:import href="str-dvc-map.xsl"/>

   <testmap:testmap/>

   <xsl:output omit-xml-declaration="yes" indent="yes"/>

   <xsl:template match="/">
     <xsl:variable name="vTestMap" select="document('')/*/testmap:*[1]"/>
     <xsl:call-template name="str-map">
       <xsl:with-param name="pFun" select="$vTestMap"/>
       <xsl:with-param name="pStr" select=
       "'123 Elm Street;PO Box 222;c/o James Jones'"/>
     </xsl:call-template>
   </xsl:template>

    <xsl:template name="replace" mode="f:FXSL"
         match="*[namespace-uri() = 'testmap']">
      <xsl:param name="arg1"/>

      <xsl:choose>
       <xsl:when test="not($arg1=';')">
        <xsl:value-of select="$arg1"/>
       </xsl:when>
       <xsl:otherwise><br /></xsl:otherwise>
      </xsl:choose>
    </xsl:template>
</xsl:stylesheet>

when this transformation is applied on any XML document (not used), the same, wanted correct result is produced:

123 Elm Street<br/>PO Box 222<br/>c/o James Jones

III. Using XSLT 2.0

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()">
  <xsl:for-each select="tokenize(.,';')">
   <xsl:sequence select="."/>
   <xsl:if test="not(position() eq last())"><br /></xsl:if>
  </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

when this transformation is applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

the wanted, correct result is produced:

123 Elm Street<br />PO Box 222<br />c/o James Jones

Countdown timer in one line

CountdownTimer(Duration(seconds: 5), Duration(seconds: 1)).listen((data){
})..onData((data){
  print('data $data');
})..onDone((){
  print('onDone.........');
});

CROSS APPLY to the rescue:

SELECT Orders.OrderNumber, topline.Quantity, topline.Description
FROM Orders
cross apply
(
    select top 1 Description,Quantity
    from LineItems 
    where Orders.OrderID = LineItems.OrderID
)topline

You can also add the order by of your choice.

Leaving aside the fact that they are private, since a and b are members of A, they are meant to be initialized by A's constructors, not by some other class's constructors (derived or not).

Try:

class A
{
    int a, b;

protected: // or public:
    A(int a, int b): a(a), b(b) {}
};

class B : public A
{
    B() : A(0, 0) {}
};

Edit: Generally try to avoid doing the below except as a last ditch effort to avoid deadlocks. Read the first comment from Stephen Cleary.

Quick fix from here. Instead of writing:

Task tsk = AsyncOperation();
tsk.Wait();

Try:

Task.Run(() => AsyncOperation()).Wait();

Or if you need a result:

var result = Task.Run(() => AsyncOperation()).Result;

From the source (edited to match the above example):

AsyncOperation will now be invoked on the ThreadPool, where there won’t be a SynchronizationContext, and the continuations used inside of AsyncOperation won’t be forced back to the invoking thread.

For me this looks like a useable option since I do not have the option of making it async all the way (which I would prefer).

From the source:

Ensure that the await in the FooAsync method doesn’t find a context to marshal back to. The simplest way to do that is to invoke the asynchronous work from the ThreadPool, such as by wrapping the invocation in a Task.Run, e.g.

int Sync() { return Task.Run(() => Library.FooAsync()).Result; }

FooAsync will now be invoked on the ThreadPool, where there won’t be a SynchronizationContext, and the continuations used inside of FooAsync won’t be forced back to the thread that’s invoking Sync().

Here is a great one http://download.oracle.com/javase/1.5.0/docs/api/

These languages are big. You cant expect a cheat sheet to fit on a piece of paper

Btw, now ruby already supports just strip without "!".

Compare:

p "abc".strip! == " abc ".strip!  # false, because "abc".strip! will return nil
p "abc".strip == " abc ".strip    # true

Also it's impossible to strip without duplicates. See sources in string.c:

static VALUE
rb_str_strip(VALUE str)
{
    str = rb_str_dup(str);
    rb_str_strip_bang(str);
    return str;
}

ruby 1.9.3p0 (2011-10-30) [i386-mingw32]

Update 1: As I see now -- it was created in 1999 year (see rev #372 in SVN):

Update2: strip! will not create duplicates — both in 1.9.x, 2.x and trunk versions.

This work for Checkbox too.

public class EnumToBoolConverter:IValueConverter
{
    private int val;
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        int intParam = (int)parameter;
        val = (int)value;

        return ((intParam & val) != 0);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        val ^= (int)parameter;
        return Enum.Parse(targetType, val.ToString());
    }
}

Binding a single enum to multiple checkboxes.

use "" with the string resource value.

Example :

<string>"value with spaces"</string>

OR

use \u0020 code for spaces.

Sure you can.

ALTER TABLE myTable ALTER COLUMN myColumn int NULL

Just substitute int for whatever datatype your column is.

A much simpler solution to this problem that allows letters, numbers and words as the label is the following code. More specifically, the line of code starting with "icon:". Any string or variable could be substituted for 'k'.

for (i = 0; i < locations.length; i++) 
      { 
      k = i + 1;
      marker = new google.maps.Marker({
      position: new google.maps.LatLng(locations[i][1], locations[i][2]),     
      map: map,
      icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=' + k + '|FF0000|000000'
});

--- the locations array holds the lat and long and k is the row number for the address I was mapping. In other words if I had a 100 addresses to map my marker labels would be 1 to 100.

Very similar to @Jonathan Wheeler:

If you do not want to remember, but not rewrite bar:

rm -r bar/
cp -r foo/ !$

!$ displays the last argument of your previous command.

I found in my case, this issue was caused by an improper configuration of build.gradle. I had two different versions of com.google.firebase. Once the versions were the same, the issue was solved

we can do like this:

in application.yml:

spring:
  profiles:
    active: test //modify here to switch between environments
    include:  application-${spring.profiles.active}.yml

in application-test.yml:

server:
  port: 5000

and in application-local.yml:

server:
  address: 0.0.0.0
  port: 8080

then spring boot will start our app as we wish to.

To extend the answer from @Kuroro, if you need to test if the property is empty, below should work.

public static bool PropertyExistsAndIsNotNull(dynamic obj, string name)
{
    if (obj == null) return false;
    if (obj is ExpandoObject)
    {
        if (((IDictionary<string, object>)obj).ContainsKey(name))
            return ((IDictionary<string, object>)obj)[name] != null;
        return false;
    }
    if (obj is IDictionary<string, object> dict1)
    {
        if (dict1.ContainsKey(name))
            return dict1[name] != null;
        return false;
    }
    if (obj is IDictionary<string, JToken> dict2)
    {
        if (dict2.ContainsKey(name))
            return (dict2[name].Type != JTokenType.Null && dict2[name].Type != JTokenType.Undefined);
        return false;
    }
    if (obj.GetType().GetProperty(name) != null)
        return obj.GetType().GetProperty(name).GetValue(obj) != null;
    return false;
}

You can simply return if you want to skip the current iteration.

Since you're in a function, if you return before doing anything else, then you have effectively skipped execution of the code below the return statement.

You should use the sessionStorage instead if you want the key to be deleted when the browser close.

This is bit out of context but in case you are here because you want to tag a specific commit like i do

Here's a command to do that :-

Example:

git tag -a v1.0 7cceb02 -m "Your message here"

Where 7cceb02 is the beginning part of the commit id.

You can then push the tag using git push origin v1.0.

You can do git log to show all the commit id's in your current branch.

Here's a nice class that is taken from here:

You mentioned that you've created an class that extends SQLiteOpenHelper and implemented the onCreate method. Are you making sure that you're performing all your database acquire calls with that class? You should only be getting SQLiteDatabase objects via the SQLiteOpenHelper#getWritableDatabase and getReadableDatabase otherwise the onCreate method will not be called when necessary. If you are doing that already check and see if th SQLiteOpenHelper#onUpgrade method is being called instead. If so, then the database version number was changed at some point in time but the table was never created properly when that happened.

As an aside, you can force the recreation of the database by making sure all connections to it are closed and calling Context#deleteDatabase and then using the SQLiteOpenHelper to give you a new db object.

These helped me a lot: I wanted to save values from my gridview, and it was reloading my gridview /overriding my new values, as i have IsPostBack inside my PageLoad.

You can safeguard yourself either of these two ways:

function myFunc(thing) {
    if (thing && thing.foo && thing.foo.bar) {
        // safe to use thing.foo.bar here
    }
}

function myFunc(thing) {
    try {
        var x = thing.foo.bar;
        // do something with x
    } catch(e) {
        // do whatever you want when thing.foo.bar didn't work
    }
}

In the first example, you explicitly check all the possible elements of the variable you're referencing to make sure it's safe before using it so you don't get any unplanned reference exceptions.

In the second example, you just put an exception handler around it. You just access thing.foo.bar assuming it exists. If it does exist, then the code runs normally. If it doesn't exist, then it will throw an exception which you will catch and ignore. The end result is the same. If thing.foo.bar exists, your code using it executes. If it doesn't exist that code does not execute. In all cases, the function runs normally.

The if statement is faster to execute. The exception can be simpler to code and use in complex cases where there may be many possible things to protect against and your code is structured so that throwing an exception and handling it is a clean way to skip execution when some piece of data does not exist. Exceptions are a bit slower when the exception is thrown.

You can't really compare NA with another value, so using == would not work. Consider the following:

You can just change your comparison from == to %in%:

ifelse(is.na(test$time) | test$type %in% "A", NA, "1")
# [1] NA  "1" NA  "1"

Regarding your other question,

I could get this to work with my existing code if I could somehow change the result of is.na(test$type) to return FALSE instead of TRUE, but I'm not sure how to do that.

just use ! to negate the results:

!is.na(test$time)
# [1]  TRUE  TRUE FALSE  TRUE

Here's the strsplit solution if s is a vector:

> s <- c("TGAS_1121", "MGAS_1432")
> s1 <- sapply(strsplit(s, split='_', fixed=TRUE), function(x) (x[2]))
> s1
[1] "1121" "1432"

Old question but nowadays CSS3 makes vertical alignment really simple!

Just add to the <div> this css:

display:flex;
align-items:center;
justify-content:center;

    align-items:center;_x000D_
    justify-content:center;_x000D_
}

<div class="img_thumb">_x000D_
    <a class="images_class" href="http://i.imgur.com/2FMLuSn.jpg" rel="images">_x000D_
       <img src="http://i.imgur.com/2FMLuSn.jpg" title="img_title" alt="img_alt" />_x000D_
    </a>_x000D_
</div>

String blah = "HellO";
int count = 0;
for (char c : blah.toCharArray()) {
    count++;
}
System.out.println("blah's length: " + count);

I like the idea of using a directive for this:

.directive('stopEvent', function () {
    return {
        restrict: 'A',
        link: function (scope, element, attr) {
            element.bind('click', function (e) {
                e.stopPropagation();
            });
        }
    };
 });

Then use the directive like:

<div ng-controller="OverlayCtrl" class="overlay" ng-click="hideOverlay()">
    <img src="http://some_src" ng-click="nextImage()" stop-event/>
</div>

If you wanted, you could make this solution more generic like this answer to a different question: https://stackoverflow.com/a/14547223/347216

Depending how you want to implement it (if there was a specific location you wanted the scripts) you could implement a @section within your _Layout which would enable you to add additional scripts from the view itself, while still retaining structure. e.g.

_Layout

<!DOCTYPE html>
<html>
  <head>
    <title>...</title>
    <script src="@Url.Content("~/Scripts/jquery.min.js")"></script>
    @RenderSection("Scripts",false/*required*/)
  </head>
  <body>
    @RenderBody()
  </body>
</html>

View

@model MyNamespace.ViewModels.WhateverViewModel
@section Scripts
{
  <script src="@Url.Content("~/Scripts/jqueryFoo.js")"></script>
}

Otherwise, what you have is fine. If you don't mind it being "inline" with the view that was output, you can place the <script> declaration within the view.

You can create a new row with $ in your data frame corresponding to the Means

DF$Mean <- rowMeans(DF[,2:4])

Just to add my two cents to @dbr's answer, following is an example of how to implement this sentence from the official documentation he's cited:

"[...] to return a string that would yield an object with the same value when passed to eval(), [...]"

Given this class definition:

class Test(object):
    def __init__(self, a, b):
        self._a = a
        self._b = b

    def __str__(self):
        return "An instance of class Test with state: a=%s b=%s" % (self._a, self._b)

    def __repr__(self):
        return 'Test("%s","%s")' % (self._a, self._b)

Now, is easy to serialize instance of Test class:

x = Test('hello', 'world')
print 'Human readable: ', str(x)
print 'Object representation: ', repr(x)
print

y = eval(repr(x))
print 'Human readable: ', str(y)
print 'Object representation: ', repr(y)
print

So, running last piece of code, we'll get:

Human readable:  An instance of class Test with state: a=hello b=world
Object representation:  Test("hello","world")

Human readable:  An instance of class Test with state: a=hello b=world
Object representation:  Test("hello","world")

But, as I said in my last comment: more info is just here!

If you have a package.json, you can install all the current project dependencies using:

npm install

Check you routes, the update on 9/28/2014 impacted us. We had to adjust our older servers and add new routes. Here is the article http://www.rackspace.com/knowledge_center/article/updating-servicenet-routes-on-cloud-servers-created-before-june-3-2013

use this library http://dart.googlecode.com/svn/branches/bleeding_edge/dart/lib/math/random.dart provided a good random generator which i think will be included in the sdk soon hope it helps

extern "C" is meant to be recognized by a C++ compiler and to notify the compiler that the noted function is (or will be) compiled in C style, so that while linking, it links to the correct version of the function from C.

In OSX El Capitan update when you do this:

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

it throws an error like

ln: /usr/lib/libmysqlclient.18.dylib: Operation not permitted

So to avoid this, what you can do is first locate libmysqlclient.18.dylib using the command

User$ locate libmysqlclient.18.dylib

In my case it returned /usr/local/mysql-5.5.24-osx10.5-x86_64/lib/libmysqlclient.18.dylib

So instead of usr/lib/ we will create symlink to usr/local/lib/ like this :

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/local/lib/libmysqlclient.18.dylib

Unfortunately as I am forced to use a windows server I have been unable to get openssl working in the way the above answer suggests.

However I was able to get a similar program called stunnel (which can be downloaded from here) to work. I got the idea from www.tech-and-dev.com but I had to change the instructions slightly. Here is what I did:

1. Install telnet client on the windows box.
2. Download stunnel. (I downloaded and installed a file called stunnel-4.56-installer.exe).
3. Once installed you then needed to locate the stunnel.conf config file, which in my case I installed to C:\Program Files (x86)\stunnel

4. Then, you need to open this file in a text viewer such as notepad. Look for [gmail-smtp] and remove the semicolon on the client line below (in the stunnel.conf file, every line that starts with a semicolon is a comment). You should end up with something like:

   [gmail-smtp]
   client = yes
   accept = 127.0.0.1:25
   connect = smtp.gmail.com:465
   

   Once you have done this save the stunnel.conf file and reload the config (to do this use the stunnel GUI program, and click on configuration=>Reload).

Now you should be ready to send email in the windows telnet client!
Go to Start=>run=>cmd.

Once cmd is open type in the following and press Enter:

telnet localhost 25

You should then see something similar to the following:

220 mx.google.com ESMTP f14sm1400408wbe.2

You will then need to reply by typing the following and pressing enter:

helo google

This should give you the following response:

250 mx.google.com at your service

If you get this you then need to type the following and press enter:

ehlo google

This should then give you the following response:

250-mx.google.com at your service, [212.28.228.49]
250-SIZE 35651584
250-8BITMIME
250-AUTH LOGIN PLAIN XOAUTH
250 ENHANCEDSTATUSCODES

Now you should be ready to authenticate with your Gmail details. To do this type the following and press enter:

AUTH LOGIN

This should then give you the following response:

334 VXNlcm5hbWU6

This means that we are ready to authenticate by using our gmail address and password.

However since this is an encrypted session, we're going to have to send the email and password encoded in base64. To encode your email and password, you can use a converter program or an online website to encode it (for example base64 or search on google for ’base64 online encoding’). I reccomend you do not touch the cmd/telnet session again until you have done this.

For example [email protected] would become dGVzdEBnbWFpbC5jb20= and password would become cGFzc3dvcmQ=

Once you have done this copy and paste your converted base64 username into the cmd/telnet session and press enter. This should give you following response:

334 UGFzc3dvcmQ6

Now copy and paste your converted base64 password into the cmd/telnet session and press enter. This should give you following response if both login credentials are correct:

235 2.7.0 Accepted

You should now enter the sender email (should be the same as the username) in the following format and press enter:

MAIL FROM:<[email protected]>

This should give you the following response:

250 2.1.0 OK x23sm1104292weq.10

You can now enter the recipient email address in a similar format and press enter:

RCPT TO:<[email protected]>

This should give you the following response:

250 2.1.5 OK x23sm1104292weq.10

Now you will need to type the following and press enter:

DATA

Which should give you the following response:

354  Go ahead x23sm1104292weq.10

Now we can start to compose the message! To do this enter your message in the following format (Tip: do this in notepad and copy the entire message into the cmd/telnet session):

From: Test <[email protected]>
To: Me <[email protected]>
Subject: Testing email from telnet
This is the body

Adding more lines to the body message.

When you have finished the email enter a dot:

.

This should give you the following response:

250 2.0.0 OK 1288307376 x23sm1104292weq.10

And now you need to end your session by typing the following and pressing enter:

QUIT

This should give you the following response:

221 2.0.0 closing connection x23sm1104292weq.10
Connection to host lost.

And your email should now be in the recipient’s mailbox!

Use jquery starts with attribute selector

$('[id^=editDialog]')

Alternative solution - 1 (highly recommended)

A cleaner solution is to add a common class to each of the divs & use

$('.commonClass').

But you can use the first one if html markup is not in your hands & cannot change it for some reason.

Alternative solution - 2 (not recommended if n is a large number) (as per @Mihai Stancu's suggestion)

$('#editDialog-0, #editDialog-1, #editDialog-2,...,#editDialog-n')

Note: If there are 2 or 3 selectors and if the list doesn't change, this is probably a viable solution but it is not extensible because we have to update the selectors when there is a new ID in town.

If you're not opposed to implicit type casting I'll offer this an alternative solution. Is it more readable with better formatting? You be the judge.

DECLARE  @StartDate datetime = '10/01/2012 08:40:18.000'
        ,@EndDate   datetime = '10/04/2012 09:52:48.000'

SELECT
    STR(ss/3600, 5) + ':' + RIGHT('0' + LTRIM(ss%3600/60), 2) + ':' + RIGHT('0' + LTRIM(ss%60), 2) AS [hh:mm:ss]
FROM (VALUES(DATEDIFF(s, @StartDate, @EndDate))) seconds (ss)

For a single dimension array, you use the Length property:

int size = theArray.Length;

For multiple dimension arrays the Length property returns the total number of items in the array. You can use the GetLength method to get the size of one of the dimensions:

int size0 = theArray.GetLength(0);

I have not used pyserial but based on the API documentation at https://pyserial.readthedocs.io/en/latest/shortintro.html it seems like a very nice interface. It might be worth double-checking the specification for AT commands of the device/radio/whatever you are dealing with.

Specifically, some require some period of silence before and/or after the AT command for it to enter into command mode. I have encountered some which do not like reads of the response without some delay first.

Escape the backslash:

if message.value[0] == "/" or message.value[0] == "\\":

From the documentation:

The backslash (\) character is used to escape characters that otherwise have a special meaning, such as newline, backslash itself, or the quote character.

I had the same problem. The only thing that solved it was merge the content of META-INF/spring.handler and META-INF/spring.schemas of each spring jar file into same file names under my META-INF project.

This two threads explain it better:

• maven assembly plugin and spring namespace handlers
• Thread: unable to locate Spring NamespaceHandler for XML schema namespace
