WHERE ...
      AND (@Location is null OR (Location like '%' + @Location + '%'))
      AND (@Date is null OR (Date = @Date))

This way it is more obvious the parameter is not used when null.

String one = object.getdata();
Log.d(one,"");

If you want to load the font from the network or easily style it, you can use:

https://github.com/shellum/fontView

Example:

<!--Layout-->
<com.finalhack.fontview.FontView
        android:id="@+id/someFontIcon"
        android:layout_width="80dp"
        android:layout_height="80dp" />

//Java:
fontView.setupFont("http://blah.com/myfont.ttf", true, character, FontView.ImageType.CIRCLE);
fontView.addForegroundColor(Color.RED);
fontView.addBackgroundColor(Color.WHITE);

See jquery docs example: http://api.jquery.com/jQuery.ajax/ (about 2/3 the page)

You may be looking for following code:

    $.ajax({
     url: 'ajax/test.html',
     success: function(data) {
     $('.result').html(data);
     alert('Load was performed.');
   }
});

The version of EnterpriseLibrary on my machine had other parameters. This was working:

        SqlParameter retval = new SqlParameter("@ReturnValue", System.Data.SqlDbType.Int);
        retval.Direction = System.Data.ParameterDirection.ReturnValue;
        cmd.Parameters.Add(retval);
        db.ExecuteNonQuery(cmd);
        object o = cmd.Parameters["@ReturnValue"].Value;

I found some slides about this issue.

http://de.slideshare.net/DroidConTLV/android-crash-analysis-and-the-dalvik-garbage-collector-tools-and-tips

In this slides the author tells that it seems to be a problem with GC, if there are a lot of objects or huge objects in heap. The slide also include a reference to a sample app and a python script to analyze this issue.

Furthermore I found a hint in comment #3 on this side: https://code.google.com/p/android/issues/detail?id=53418#c3

You can actually detect when the old modal closes by calling the hidden.bs.modal event:

    $('.yourButton').click(function(e){
        e.preventDefault();

        $('#yourFirstModal')
            .modal('hide')
            .on('hidden.bs.modal', function (e) {
                $('#yourSecondModal').modal('show');

                $(this).off('hidden.bs.modal'); // Remove the 'on' event binding
            });

    });

For people that have tried above,try generating the key with the -keypass and -storepass options as I was only inputting one of the passwords when running it like the React Native docs have you. This caused it to error out when trying to build.

keytool -keypass PASSWORD1 -storepass PASSWORD2 -genkeypair -v -keystore release2.keystore -alias release2 -keyalg RSA -keysize 2048 -validity 10000

NumberFormat currency = NumberFormat.getCurrencyInstance();
String myCurrency = currency.format(123.5);
System.out.println(myCurrency);

output:

$123.50

If you want to change the currency,

NumberFormat currency = NumberFormat.getCurrencyInstance(Locale.CHINA);
String myCurrency = currency.format(123.5);
System.out.println(myCurrency);

output:

?123.50

This is my sample code for load static variable

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class OnelinkConfig {
    public static int MODULE_CODE;
    public static int DEFAULT_PAGE;
    public static int DEFAULT_SIZE;

    @Autowired
    public void loadOnelinkConfig(@Value("${onelink.config.exception.module.code}") int code,
            @Value("${onelink.config.default.page}") int page, @Value("${onelink.config.default.size}") int size) {
        MODULE_CODE = code;
        DEFAULT_PAGE = page;
        DEFAULT_SIZE = size;
    }
}

while [ -n $(passwd) ]; do
        echo "Try again";
done;

You can use ax.figure.savefig(), as suggested in a comment on the question:

import pandas as pd

df = pd.DataFrame([0, 1])
ax = df.plot.line()
ax.figure.savefig('demo-file.pdf')

This has no practical benefit over ax.get_figure().savefig() as suggested in other answers, so you can pick the option you find the most aesthetically pleasing. In fact, get_figure() simply returns self.figure:

# Source from snippet linked above
def get_figure(self):
    """Return the `.Figure` instance the artist belongs to."""
    return self.figure

Another root cause of this problem might be a difference between HTTP/1.1 and HTTP/2.

Symptom: Some users, not all of them, reported to get a CORS error when using our Software.

Problem: The Access-Control-Allow-Origin header was missing sometimes.

Context: We had a Lambda in place, dedicated to handling OPTIONS request and replying with the corresponding CORS headers, such as Access-Control-Allow-Origin matching a whitelisted Origin.

Solution: The API Gateway seems to transform all headers to lower-case for HTTP/2 calls, but maintains capitalization for HTTP/1.1. This caused the access to event.headers.origin to fail.

Check if you're having this issue too:

Assuming your API is located at https://api.example.com, and your front-end is at https://www.example.com. Using CURL, make a request using HTTP/2:

curl -v -X OPTIONS -H 'Origin: https://www.example.com' https://api.example.com

The response output should include the header:

< Access-Control-Allow-Origin: https://www.example.com

Repeat the same step using HTTP/1.1 (or with a lowercase Origin header):

curl -v -X OPTIONS --http1.1 -H 'Origin: https://www.example.com' https://api.example.com

If the Access-Control-Allow-Origin header is missing, you might want to check case sensitivity when reading the Origin header.

I know this post is about adding a single line break but I thought I would mention that you can create multiple line breaks with the backslash (\) character:

Hello
\
\
\
World!

This would result in 3 new lines after "Hello". To clarify, that would mean 2 empty lines between "Hello" and "World!". It would display like this:

World!

Personally I find this cleaner for a large number of line breaks compared to using <br>.

Note that backslashes are not recommended for compatibility reasons. So this may not be supported by your Markdown parser but it's handy when it is.

SELECT created
  FROM dba_objects
 WHERE object_name = <<your table name>>
   AND owner = <<owner of the table>>
   AND object_type = 'TABLE'

will tell you when a table was created (if you don't have access to DBA_OBJECTS, you could use ALL_OBJECTS instead assuming you have SELECT privileges on the table).

The general answer to getting timestamps from a row, though, is that you can only get that data if you have added columns to track that information (assuming, of course, that your application populates the columns as well). There are various special cases, however. If the DML happened relatively recently (most likely in the last couple hours), you should be able to get the timestamps from a flashback query. If the DML happened in the last few days (or however long you keep your archived logs), you could use LogMiner to extract the timestamps but that is going to be a very expensive operation particularly if you're getting timestamps for many rows. If you build the table with ROWDEPENDENCIES enabled (not the default), you can use

SELECT scn_to_timestamp( ora_rowscn ) last_modified_date,
       ora_rowscn last_modified_scn,
       <<other columns>>
  FROM <<your table>>

to get the last modification date and SCN (system change number) for the row. By default, though, without ROWDEPENDENCIES, the SCN is only at the block level. The SCN_TO_TIMESTAMP function also isn't going to be able to map SCN's to timestamps forever.

Can you split up the query? Insert the stored proc results into a table variable or a temp table. Then, select the 2 columns from the table variable.

Declare @tablevar table(col1 col1Type,..
insert into @tablevar(col1,..) exec MyStoredProc 'param1', 'param2'

SELECT col1, col2 FROM @tablevar

Alternatively, you can use numpy underlying function:

>>> import numpy as np
>>> df = pd.DataFrame({"A": [10,20,30], "B": [20, 30, 10]})
>>> df['new_column'] = np.multiply(df['A'], df['B'])
>>> df
    A   B  new_column
0  10  20         200
1  20  30         600
2  30  10         300

or vectorize arbitrary function in general case:

>>> def fx(x, y):
...     return x*y
...
>>> df['new_column'] = np.vectorize(fx)(df['A'], df['B'])
>>> df
    A   B  new_column
0  10  20         200
1  20  30         600
2  30  10         300

If you want headless browser support then there is another approach you might adopt.

https://github.com/detro/ghostdriver

It was announced during Selenium Conference and it is still in development. It uses PhantomJS as the browser and is much better than HTMLUnitDriver, there are no screenshots yet, but as it is still in active development.

Array slicing like in Python (From the rebash library):

array_slice() {
    local __doc__='
    Returns a slice of an array (similar to Python).

    From the Python documentation:
    One way to remember how slices work is to think of the indices as pointing
    between elements, with the left edge of the first character numbered 0.
    Then the right edge of the last element of an array of length n has
    index n, for example:
    ```
    +---+---+---+---+---+---+
    | 0 | 1 | 2 | 3 | 4 | 5 |
    +---+---+---+---+---+---+
    0   1   2   3   4   5   6
    -6  -5  -4  -3  -2  -1
    ```

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1:-2 "${a[@]}")
    1 2 3
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0:1 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 1:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 2:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice -2:-3 "${a[@]}")" ] && echo empty
    empty
    >>> [ -z "$(array.slice -2:-2 "${a[@]}")" ] && echo empty
    empty

    Slice indices have useful defaults; an omitted first index defaults to
    zero, an omitted second index defaults to the size of the string being
    sliced.
    >>> local a=(0 1 2 3 4 5)
    >>> # from the beginning to position 2 (excluded)
    >>> echo $(array.slice 0:2 "${a[@]}")
    >>> echo $(array.slice :2 "${a[@]}")
    0 1
    0 1

    >>> local a=(0 1 2 3 4 5)
    >>> # from position 3 (included) to the end
    >>> echo $(array.slice 3:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice 3: "${a[@]}")
    3 4 5
    3 4 5

    >>> local a=(0 1 2 3 4 5)
    >>> # from the second-last (included) to the end
    >>> echo $(array.slice -2:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice -2: "${a[@]}")
    4 5
    4 5

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -4:-2 "${a[@]}")
    2 3

    If no range is given, it works like normal array indices.
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -1 "${a[@]}")
    5
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -2 "${a[@]}")
    4
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1 "${a[@]}")
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice 6 "${a[@]}"; echo $?
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice -7 "${a[@]}"; echo $?
    1
    '
    local start end array_length length
    if [[ $1 == *:* ]]; then
        IFS=":"; read -r start end <<<"$1"
        shift
        array_length="$#"

It seems that you've omitted the value attribute in HTML markup.

Add it there as <input value="" ... >.

Shift-tab doesn't seem to work on multi-lines in Aptana. It also doesn't work on single lines with a single preceding space. Any workarounds? I use shift-tab (outdent) to fix badly formatted code all the time.

I miss NetBeans ...

UPDATE: it works on multi-newlines, if the multi-lines have the same level of indentation. It should just continue outdenting the other lines that haven't reached the beginning of the new line yet. Is there an option to change this I wonder?

I had to disable this in chrome://flags

Create a listview item

ListViewItem item1 = new ListViewItem("sdasdasdasd", 0)
item1.SubItems.Add("asdasdasd")

You can import them as

import {concat, filter, orderBy} from 'lodash';

or as

import concat from 'lodash/concat';
import orderBy from 'lodash/orderBy';
import filter from 'lodash/filter';

the second one is much optimized than the first because it only loads the needed modules

then use like this

pendingArray: concat(
                    orderBy(
                        filter(payload, obj => obj.flag),
                        ['flag'],
                        ['desc'],
                    ),
                    filter(payload, obj => !obj.flag),

You can add Apache Commons Lang in Gradle like compile 'org.apache.commons:commons-lang3:3.4'

And use WordUtils.capitalizeFully(name)

You can get lat, lng from the place object i.e.

var place = autocomplete.getPlace();

var latitude = place.geometry.location.lat();
var longitude = place.geometry.location.lng();

As, Luc Touraille has already explained it very well where to use and not use forward declaration of the class.

I will just add to that why we need to use it.

We should be using Forward declaration wherever possible to avoid the unwanted dependency injection.

As #include header files are added on multiple files therefore, if we add a header into another header file it will add unwanted dependency injection in various parts of source code which can be avoided by adding #include header into .cpp files wherever possible rather than adding to another header file and use class forward declaration wherever possible in header .h files.

Yes. Only comments and the end tag for the html element are allowed after the end tag for the body.

Browsers may perform error recovery, but you should never depend on that.

git reset HEAD <file> 

for removing a particular file from the index.

and

git reset HEAD

for removing all indexed files.

Open database properties --> options and set Database read-only to False.

• Make sure you logged into the SQL Management Studio using Windows Authentication.
• Make sure your user has write access to the directory of the mdf and log files.

Did the trick for me...

I found the "cross module" answer above very helpful to my situation, but would want to expand on that, as there is another wrinkle to consider. If you have a submodule, it also can't see the pipes in the parent module in my testing. For that reason also, you may need to put pipes into there own separate module.

Here's a summary of the steps I took to address pipes not being visible in the submodule:

1. Take pipes out of (parent) SharedModule and put into PipeModule
2. In SharedModule, import PipeModule and export (for other parts of app dependent on SharedModule to automatically gain access to PipeModule)
3. For Sub-SharedModule, import PipeModule, so it can gain access to PipeModule, without having to re-import SharedModule which would create a circular dependency issue, among other problems.

Another footnote to the above "cross module" answer: when I created the PipeModule I removed the forRoot static method and imported PipeModule without that in my shared module. My basic understanding is that forRoot is useful for scenarios like singletons, which don't apply to filters necessarily.

It is not possible to dynamically change the value of a file field, otherwise you could set it to "c:\yourfile" and steal files very easily.

However there are many solutions to a multi-upload system. I'm guessing that you're wanting to have a multi-select open dialog.

Perhaps have a look at http://www.plupload.com/ - it's a very flexible solution to multiple file uploads, and supports drop zones e.t.c.

If you want to do it with multiline/multiple command/s then you can do this:

output=$( bash <<EOF
#multiline/multiple command/s
EOF
)

Or:

output=$(
#multiline/multiple command/s
)

Example:

#!/bin/bash
output="$( bash <<EOF
echo first
echo second
echo third
EOF
)"
echo "$output"

Output:

first
second
third

dplyr now has a function case_when that offers a vectorised if. The syntax is a little strange compared to mosaic:::derivedFactor as you cannot access variables in the standard dplyr way, and need to declare the mode of NA, but it is considerably faster than mosaic:::derivedFactor.

df %>%
mutate(g = case_when(a %in% c(2,5,7) | (a==1 & b==4) ~ 2L, 
                     a %in% c(0,1,3,4) | c == 4 ~ 3L, 
                     TRUE~as.integer(NA)))

EDIT: If you're using dplyr::case_when() from before version 0.7.0 of the package, then you need to precede variable names with '.$' (e.g. write .$a == 1 inside case_when).

Benchmark: For the benchmark (reusing functions from Arun 's post) and reducing sample size:

require(data.table) 
require(mosaic) 
require(dplyr)
require(microbenchmark)

set.seed(42) # To recreate the dataframe
DT <- setDT(lapply(1:6, function(x) sample(7, 10000, TRUE)))
setnames(DT, letters[1:6])
DF <- as.data.frame(DT)

DPLYR_case_when <- function(DF) {
  DF %>%
  mutate(g = case_when(a %in% c(2,5,7) | (a==1 & b==4) ~ 2L, 
                       a %in% c(0,1,3,4) | c==4 ~ 3L, 
                       TRUE~as.integer(NA)))
}

DT_fun <- function(DT) {
  DT[(a %in% c(0,1,3,4) | c == 4), g := 3L]
  DT[a %in% c(2,5,7) | (a==1 & b==4), g := 2L]
}

DPLYR_fun <- function(DF) {
  mutate(DF, g = ifelse(a %in% c(2,5,7) | (a==1 & b==4), 2L, 
                    ifelse(a %in% c(0,1,3,4) | c==4, 3L, NA_integer_)))
}

mosa_fun <- function(DF) {
  mutate(DF, g = derivedFactor(
    "2" = (a == 2 | a == 5 | a == 7 | (a == 1 & b == 4)),
    "3" = (a == 0 | a == 1 | a == 4 | a == 3 |  c == 4),
    .method = "first",
    .default = NA
  ))
}

perf_results <- microbenchmark(
  dt_fun <- DT_fun(copy(DT)),
  dplyr_ifelse <- DPLYR_fun(copy(DF)),
  dplyr_case_when <- DPLYR_case_when(copy(DF)),
  mosa <- mosa_fun(copy(DF)),
  times = 100L
)

This gives:

Based on solution You've already found How to apply CSS to iframe?:

var cssLink = document.createElement("link") 
cssLink.href = "file://path/to/style.css"; 
cssLink .rel = "stylesheet"; 
cssLink .type = "text/css"; 
frames['iframe'].document.body.appendChild(cssLink);

or more jqueryish (from Append a stylesheet to an iframe with jQuery):

var $head = $("iframe").contents().find("head");

Update 2016: seems to be working again.

Update August 2014: No longer works as of recent Chrome versions.

Yeah, the new state of affairs sucks. Fortunately it's not so hard as the other answers imply.

1. Browse in Chrome to chrome://extensions
2. Drag the .user.js file into that page.

Voila. You can also drag files from the downloads footer bar to the extensions tab.

Chrome will automatically create a manifest.json file in the extensions directory that Brock documented.

The best practice is to use a style sheet specifically for printing, and and set its media attribute to print.

In it, show/hide the elements that you want to be printed on paper.

<link rel="stylesheet" type="text/css" href="print.css" media="print" />

First of all, with regards to FormatType.JSON: JSON is not a member of FormatType, it's a possible value of the type. FormatType isn't even a composite type — it's a scalar.

Second, the only way to do this is to create a mapping table. The more common way to do this in Objective-C is to create a series of constants referring to your "symbols", so you'd have NSString *FormatTypeJSON = @"JSON" and so on.

This happened when I tried installing over top of an adhoc build.

#include <iostream.h>
#include<typeinfo.h>

template<class T>
void fun(T a)
{
  if(typeid(T) == typeid(int))
  {
     //Do something
     cout<<"int";
  }
  else if(typeid(T) == typeid(float))
  {
     //Do Something else
     cout<<"float";
  }
}

void main()
 {
      fun(23);
      fun(90.67f);
 }

Here is my sample, is based on Django + Dropzone. View has select(required) and submit.

<form action="/share/upload/" class="dropzone" id="uploadDropzone">
    {% csrf_token %}
        <select id="warehouse" required>
            <option value="">Select a warehouse</option>
                {% for warehouse in warehouses %}
                    <option value={{forloop.counter0}}>{{warehouse.warehousename}}</option>
                {% endfor %}
        </select>
    <button id="submit-upload btn" type="submit">upload</button>
</form>

<script src="{% static '/js/libs/dropzone/dropzone.js' %}"></script>
<script src="https://code.jquery.com/jquery-3.1.0.min.js"></script>
<script>
    var filename = "";

    Dropzone.options.uploadDropzone = {
        paramName: "file",  // The name that will be used to transfer the file,
        maxFilesize: 250,   // MB
        autoProcessQueue: false,
        accept: function(file, done) {
            console.log(file.name);
            filename = file.name;
            done();    // !Very important
        },
        init: function() {
            var myDropzone = this,
            submitButton = document.querySelector("[type=submit]");

            submitButton.addEventListener('click', function(e) {
                var isValid = document.querySelector('#warehouse').reportValidity();
                e.preventDefault();
                e.stopPropagation();
                if (isValid)
                    myDropzone.processQueue();
            });

            this.on('sendingmultiple', function(data, xhr, formData) {
                formData.append("warehouse", jQuery("#warehouse option:selected").val());
            });
        }
    };
</script>

It looks like a 32/64 bit mismatch. The ldd output shows that mainly libraries from /lib64 are chosen. That would indicate that you have installed a 64 bit version of the Oracle client and have created a 64 bit executable. But libaio.so is probably a 32 bit library and cannot be used for your application.

So you either need a 64 bit version of libaio or you create a 32 bit version of your application.

Size of some float types may exceed the size of int. This example shows a safe conversion of any float type to int using the int safeFloatToInt(const FloatType &num); function:

#include <iostream>
#include <limits>
using namespace std;

template <class FloatType>
int safeFloatToInt(const FloatType &num) {
   //check if float fits into integer
   if ( numeric_limits<int>::digits < numeric_limits<FloatType>::digits) {
      // check if float is smaller than max int
      if( (num < static_cast<FloatType>( numeric_limits<int>::max())) &&
          (num > static_cast<FloatType>( numeric_limits<int>::min())) ) {
         return static_cast<int>(num); //safe to cast
      } else {
        cerr << "Unsafe conversion of value:" << num << endl;
        //NaN is not defined for int return the largest int value
        return numeric_limits<int>::max();
      }
   } else {
      //It is safe to cast
      return static_cast<int>(num);
   }
}
int main(){
   double a=2251799813685240.0;
   float b=43.0;
   double c=23333.0;
   //unsafe cast
   cout << safeFloatToInt(a) << endl;
   cout << safeFloatToInt(b) << endl;
   cout << safeFloatToInt(c) << endl;
   return 0;
}

Result:

Unsafe conversion of value:2.2518e+15

If you want to find the button only by its class name and using jQLite only, you can do like below:

var myListButton = $document.find('button').filter(function() {
    return angular.element(this).hasClass('multi-files');
});

Hope this helps. :)

@gdbj's answer is a great explanation and the most up to date answer. Here's however a simpler approach.

So if you want to redirect all traffic from nginx listening to 80 to another container exposing 8080, minimum configuration can be as little as:

nginx.conf:

server {
    listen 80;

    location / {
        proxy_pass http://client:8080; # this one here
        proxy_redirect off;
    }

}

docker-compose.yml

version: "2"
services:
  entrypoint:
    image: some-image-with-nginx
    ports:
      - "80:80"
    links:
      - client  # will use this one here

  client:
    image: some-image-with-api
    ports:
      - "8080:8080"

Docker docs

While expression:

"string1" + "string2" + "string3"

will concatenate the string, you need to put a $ in front of the parenthesis to make it evaluate as a single argument when passed to a PowerShell command. Example:

Write-Host $( "string1" + "string2" + "string3" )

As a bonus, if you want it to span multiple lines, then you need to use the awkward backtick syntax at the end of the line (without any spaces or characters to the right of the backtick).

Example:

Write-Host $(`
    "The rain in "        +`
    "Spain falls mainly " +`
    "in the plains"       )`
    -ForegroundColor Yellow

(Actually, I think PowerShell is currently implemented a little bit wrong by requiring unnecessary backticks between parentheses. If Microsoft would just follow Python or Tcl parenthesis rules of allowing you to put as many newlines as you want between the starting and ending parenthesis then they would solve most of the problems that people don't like about PowerShell related to line continuation, and concatenation of strings.

I've found that you can leave the backticks off sometimes on line continuations between parenthesis, but it's really flaky and unpredictable if it will work... It's better to just add the backticks.)

What does

$ git config --get-regexp '^(remote|branch)\.'

returns (executed within your git repository) ?

Origin is just a default naming convention for referring to a remote Git repository.

If it does not refer to GitHub (but rather a path to your teammate repository, path which may no longer be valid or available), just add another origin, like in this Bloggitation entry

$ git remote add origin2 [email protected]:myLogin/myProject.git
$ git push origin2 master

(I would actually use the name 'github' rather than 'origin' or 'origin2')

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

Check if your gitHub identity is correctly declared in your local Git repository, as mentioned in the GitHub Help guide. (both user.name and github.name -- and github.token)

Then, stonean blog suggests (as does Marcio Garcia):

$ cd ~/.ssh
$ ssh-add id_rsa

Aral Balkan adds: create a config file

The solution was to create a config file under ~/.ssh/ as outlined at the bottom of the OS X section of this page.

Here's the file I added, as per the instructions on the page, and my pushes started working again:

Host github.com
User git
Port 22
Hostname github.com
IdentityFile ~/.ssh/id_rsa
TCPKeepAlive yes
IdentitiesOnly yes

You can also post the result of

ssh -v [email protected]

to have more information as to why GitHub ssh connection rejects you.

Check also you did enter correctly your public key (it needs to end with '==').
Do not paste your private key, but your public one. A public key would look something like:

ssh-rsa AAAAB3<big string here>== [email protected] 

(Note: did you use a passphrase for your ssh keys ? It would be easier without a passphrase)

Check also the url used when pushing ([email protected]/..., not git://github.com/...)

Check that you do have a SSH Agent to use and cache your key.

Try this:

 $ ssh -i path/to/public/key [email protected]

If that works, then it means your key is not being sent to GitHub by your ssh client.

The issue seems to be resolved with the new Eclipse. The plugin isn't available with Java Enterprise suite.

Keys must be comparable, but you haven't defined a suitable operator< for your custom class.

Here's my attempt to solve it in Java. Apologies for the non-standard formatting, but the code has a lot of duplication, and this is the best I can do to make it readable.

import java.util.Arrays;

public class Products {
    static int[] products(int... nums) {
        final int N = nums.length;
        int[] prods = new int[N];
        Arrays.fill(prods, 1);
        for (int
           i = 0, pi = 1    ,  j = N-1, pj = 1  ;
           (i < N)         && (j >= 0)          ;
           pi *= nums[i++]  ,  pj *= nums[j--]  )
        {
           prods[i] *= pi   ;  prods[j] *= pj   ;
        }
        return prods;
    }
    public static void main(String[] args) {
        System.out.println(
            Arrays.toString(products(1, 2, 3, 4, 5))
        ); // prints "[120, 60, 40, 30, 24]"
    }
}

The loop invariants are pi = nums[0] * nums[1] *.. nums[i-1] and pj = nums[N-1] * nums[N-2] *.. nums[j+1]. The i part on the left is the "prefix" logic, and the j part on the right is the "suffix" logic.

Recursive one-liner

Jasmeet gave a (beautiful!) recursive solution; I've turned it into this (hideous!) Java one-liner. It does in-place modification, with O(N) temporary space in the stack.

static int multiply(int[] nums, int p, int n) {
    return (n == nums.length) ? 1
      : nums[n] * (p = multiply(nums, nums[n] * (nums[n] = p), n + 1))
          + 0*(nums[n] *= p);
}

int[] arr = {1,2,3,4,5};
multiply(arr, 1, 0);
System.out.println(Arrays.toString(arr));
// prints "[120, 60, 40, 30, 24]"

In the project right click

-> new -> module
-> import jar/AAR package
-> import select the jar file to import
-> click ok -> done

Follow the screenshots below:

You will see this:

I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).

The only difference would be if you try to reassign it before the end of this very file.

@RestController is composition of @Controller and @ResponseBody, if we are not using the @ResponseBody in Method signature then we need to use the @Restcontroller.

Comparator<User> cmp = new Comparator<User>() {
    @Override
    public int compare(User user1, User user2) {
        return user1.date.compareTo(user2.date);
    }
};

Collections.max(list, cmp);

I know several responses have suggested exporting the file to csv or some other text format, and then comparing them. I haven't seen it mentioned specifically, but Beyond Compare 3 has a number of additional file formats that it supports. See Additional File Formats. Using one of the Microsoft Excel File Formats you can easily compare two Excel files without going through the export to another format option.

Well you are trying to compare Date with Nvarchar which is wrong. Should be

Where dates between date1 And date2
-- both date1 & date2 should be date/datetime

If date1,date2 strings; server will convert them to date type before filtering.

Since the question is so popular, it may be useful to add on what to do if you want to control the type property name and its value.

The long way is to write custom JsonConverters to handle (de)serialization by manually checking and setting the type property.

A simpler way is to use JsonSubTypes, which handles all the boilerplate via attributes:

[JsonConverter(typeof(JsonSubtypes), "Sound")]
[JsonSubtypes.KnownSubType(typeof(Dog), "Bark")]
[JsonSubtypes.KnownSubType(typeof(Cat), "Meow")]
public class Animal
{
    public virtual string Sound { get; }
    public string Color { get; set; }
}

public class Dog : Animal
{
    public override string Sound { get; } = "Bark";
    public string Breed { get; set; }
}

public class Cat : Animal
{
    public override string Sound { get; } = "Meow";
    public bool Declawed { get; set; }
}

This one liner gives you the IP address:

(Test-Connection -ComputerName $env:computername -count 1).ipv4address.IPAddressToString

Include it in a Variable?

$IPV4=(Test-Connection -ComputerName $env:computername -count 1).ipv4address.IPAddressToString

BigJacko's Javascript code worked for me, but in my case I first had to add some JQuery "noconflict" code. Here's the revised version that worked on my site:

<script type="text/javascript">
var $j = jQuery.noConflict(); 
jQuery(document).ready(function($j){
  $j('iframe').each(function() {
    var url = $j(this).attr("src");
      if ($j(this).attr("src").indexOf("?") > 0) {
        $j(this).attr({
          "src" : url + "&wmode=transparent",
          "wmode" : "Opaque"
        });
      }
      else {
        $j(this).attr({
          "src" : url + "?wmode=transparent",
           "wmode" : "Opaque"
        });
      }
   });
});
</script>

Another choice besides JObject is System.Json.JsonValue for Weak-Typed JSON object.

It also has a JsonValue blob = JsonValue.Parse(json); you can use. The blob will most likely be of type JsonObject which is derived from JsonValue, but could be JsonArray. Check the blob.JsonType if you need to know.

And to answer you question, YES, you may replace json with the name of your actual variable that holds the JSON string. ;-D

There is a System.Json.dll you should add to your project References.

sample code show custom dialog in kotlin:

fun showDlgFurtherDetails(context: Context,title: String?, details: String?) {

    val dialog = Dialog(context)
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
    dialog.setCancelable(false)
    dialog.setContentView(R.layout.dlg_further_details)
    dialog.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
    val lblService = dialog.findViewById(R.id.lblService) as TextView
    val lblDetails = dialog.findViewById(R.id.lblDetails) as TextView
    val imgCloseDlg = dialog.findViewById(R.id.imgCloseDlg) as ImageView

    lblService.text = title
    lblDetails.text = details
    lblDetails.movementMethod = ScrollingMovementMethod()
    lblDetails.isScrollbarFadingEnabled = false
    imgCloseDlg.setOnClickListener {
        dialog.dismiss()
    }
    dialog.show()
}

If you run ps -aux | dockerd you should see the tcp endpoint it is running on.

3 Ways to Install Applications On Android Without The Market

And don't forget to enable Unknown sources in your Android device Settings, before installing apk, else Android platform will not allow you to install apk directly

you need to type it in cmd not in the IDLE. becuse IDLE is not an command prompt if you want to install something from IDLE type this

>>>from pip.__main__ import _main as main
>>>main(#args splitted by space in list example:['install', 'requests'])

this is calling pip like pip <commands> in terminal. The commands will be seperated by spaces that you are doing there to.

String s1 = "Welcome"; // Does not create a new instance  
String s2 = new String("Welcome"); // Creates two objects and one reference variable  

As @kirbyfan64sos notes in a comment, /home is NOT your home directory (a.k.a. home folder):

The fact that /home is an absolute, literal path that has no user-specific component provides a clue.

While /home happens to be the parent directory of all user-specific home directories on Linux-based systems, you shouldn't even rely on that, given that this differs across platforms: for instance, the equivalent directory on macOS is /Users.

What all Unix platforms DO have in common are the following ways to navigate to / refer to your home directory:

• Using cd with NO argument changes to your home dir., i.e., makes your home dir. the working directory.
  • e.g.: cd # changes to home dir; e.g., '/home/jdoe'

• Unquoted ~ by itself / unquoted ~/ at the start of a path string represents your home dir. / a path starting at your home dir.; this is referred to as tilde expansion (see man bash)
  • e.g.: echo ~ # outputs, e.g., '/home/jdoe'

• $HOME - as part of either unquoted or preferably a double-quoted string - refers to your home dir. HOME is a predefined, user-specific environment variable:
  • e.g.: cd "$HOME/tmp" # changes to your personal folder for temp. files

Thus, to create the desired folder, you could use:

mkdir "$HOME/bin"  # same as: mkdir ~/bin

Note that most locations outside your home dir. require superuser (root user) privileges in order to create files or directories - that's why you ran into the Permission denied error.

I had a similar problem, made all the more infuriating by simply being very SLOW to update. I couldn't get my changes to take effect while working on the site to save my life (trying all manner of clearing my browser cache and cookies), but if I came back to the site later in the day or opened another browser, there they were.

I also solved the problem by disabling the Supercacher software at my host's cpanel (Siteground). You can also use the "flush" button for individual directories to test if that's it before disabling.

You can use just JavaScript:

window.location = 'http://address.com';

I don't have IE8 to test this out, but I'm pretty sure it should work:

<div class="screen">
   <!-- code -->
   <div class="innerdiv">
      text or other content
   </div>
</div>

and the css:

.screen{
position: relative;
}
.innerdiv {
position: absolute;
bottom: 0;
right: 0;
}

This should place the .innerdiv in the bottom-right corner of the .screen class. I hope this helps :)

Varargs can be used when we are unsure about the number of arguments to be passed in a method. It creates an array of parameters of unspecified length in the background and such a parameter can be treated as an array in runtime.

If we have a method which is overloaded to accept different number of parameters, then instead of overloading the method different times, we can simply use varargs concept.

Also when the parameters' type is going to vary then using "Object...test" will simplify the code a lot.

For example:

public int calculate(int...list) {
    int sum = 0;
    for (int item : list) {
        sum += item;
    }
    return sum;
}

Here indirectly an array of int type (list) is passed as parameter and is treated as an array in the code.

For a better understanding follow this link(it helped me a lot in understanding this concept clearly): http://www.javadb.com/using-varargs-in-java

P.S: Even I was afraid of using varargs when I didn't knw abt it. But now I am used to it. As it is said: "We cling to the known, afraid of the unknown", so just use it as much as you can and you too will start liking it :)

In a terminal put these:

cd C:\Program Files (x86)\Google\Chrome\Application

chrome.exe --disable-web-security --user-data-dir="c:/chromedev"

Well I have a few ideas, but I don't know if they are what your looking for.

You could use a service that holds all of the data and then just bind your activities to the service for data retrival.

Or package your data into a serializable or parcelable and attach them to a bundle and pass the bundle between activities.

This one may not be at all what your looking for, but you could also try using a SharedPreferences or a preference in general.

Either way let me know what you decide.

Try this - You have to import java.util.regex.*;

    Pattern pattern = Pattern.compile("\\s+");
    Matcher matcher = pattern.matcher(string);
    boolean check = matcher.find();
    String str = matcher.replaceAll(" ");

Where string is your string on which you need to remove duplicate white spaces

Some additional test-info on @Orwellophile code using a 17.9MB textfile.
Using the property values in the code-example "as is" will have a HUGE negative impact on performance, it takes 14.16 sec.

Setting the properties to the following do the same job at 3.91 sec (i.a. the archive will have the same container info which is: you can extract and test the archive with 7zip but there are no filename information)

Native 7zip 2 sec.

CoderPropID[] propIDs =  {
  //CoderPropID.DictionarySize,
  //CoderPropID.PosStateBits,
  //CoderPropID.LitContextBits,
  //CoderPropID.LitPosBits,
  //CoderPropID.Algorithm,
  //CoderPropID.NumFastBytes,
  //CoderPropID.MatchFinder,
  CoderPropID.EndMarker
};
object[] properties = {
  //(Int32)(dictionary),
  //(Int32)(posStateBits),
  //(Int32)(litContextBits),
  //(Int32)(litPosBits),
  //(Int32)(algorithm),
  //(Int32)(numFastBytes),
  //mf,
  eos
};

I did another test using native 7zip and a 1,2GB SQL backup file (.bak)
7zip (maximum compression): 1 minute
LZMA SDK (@Orwellophile with above property-setting): 12:26 min :-(
Outputfile roughly same size.

So I guess I'll myself will use a solution based on the c/c++ engine, i.a. either call the 7zip executable from c# or use squid-box/SevenZipSharp, which is a wrapper around the 7zip c/c++ dll file, and seems to be the newest fork of SevenZipSharp. Haven't tested the wrapper, but I hope is perform just as the native 7zip. But hopefully it will give the possibility to compress stream also which you obvious cannot if you call the exe directly. Otherwise I guess there isn't mush advantage over calling the exe. The wrapper have some additional dependencies so it will not make your published project "cleaner".

By the way it seems the .Net Core team consider implementing LZMA in the system.io class in .Core ver. 5, that would be great!

(I know this is kind of a comment and not an answer but to be able to provide the code snippet it couldn't be a comment)

I'm not sure but I commonly initialize an array to "" in that case I don't need worry about the null end of the string.

main() {
    void something(char[]);
    char s[100] = "";

    something(s);
    printf("%s", s);
}

void something(char s[]) {
    // ... do something, pass the output to s
    // no need to add s[i] = '\0'; because all unused slot is already set to '\0'
}

In Laravel (PHP) we can do it in the following clear and elegant way (using file modification timestamp):

<script src="{{ asset('/js/your.js?v='.filemtime('js/your.js')) }}"></script>

And similar for CSS

<link rel="stylesheet" href="{{asset('css/your.css?v='.filemtime('css/your.css'))}}">

Example HTML output (filemtime return time as as a Unix timestamp)

<link rel="stylesheet" href="assets/css/your.css?v=1577772366">

If you are using Laravel eloquent you may try this as well.

$result = self::select('*')
                    ->with('user')
                    ->where('subscriptionPlan', function($query) use($activated){
                        $query->where('activated', '=', $roleId);
                    })
                    ->get();

A simple method will be like this:

Match match1 = Regex.Match(<input_string>, @"(?=.{7})");   

match1.Success ensures that there are at least 8 characters.

Match match2 = Regex.Match(<input_string>, [^a-zA-Z]);

match2.Success ensures that there is at least one special character or number within the string.

So, match1.Success && match2.Success guarantees will get what you want.

This is possible with CSS3. Just use position: sticky, as seen here.

position: -webkit-sticky; /* Safari & IE */
position: sticky;
top: 0;

I'm not sure if this will still be useful to people, but with ES6 I have a way to do it that I find clean and useful.

class MyClass { 
  constructor ( arg1, arg2, arg3 )
  myFunction1 () {...}
  myFunction2 () {...}
  myFunction3 () {...}
}

module.exports = ( arg1, arg2, arg3 ) => { return new MyClass( arg1,arg2,arg3 ) }

And then you get your expected behaviour.

var MyClass = require('/MyClass.js')( arg1, arg2, arg3 )

Use the Len function

length = Len(myString)

/*$mpdf = new mPDF('',    // mode - default ''
 '',    // format - A4, for example, default ''
 0,     // font size - default 0
 '',    // default font family
 15,    // margin_left
 15,    // margin right
 16,     // margin top
 16,    // margin bottom
 9,     // margin header
 9,     // margin footer
 'L');  // L - landscape, P - portrait*/

>Try this its working fine for the multiple output parameter:

CREATE PROCEDURE [endicia].[credentialLookup]
@accountNumber varchar(20),
@login varchar(20) output,
@password varchar(50) output
AS
BEGIN
SET NOCOUNT ON;
SELECT top 1 @login = [carrierLogin],@password = [carrierPassword]
  FROM [carrier_account] where carrierLogin = @accountNumber
  order by clientId, id
END

Try for the result: 
SELECT *FROM [carrier_account] 
DECLARE @login varchar(20),@password varchar(50)
exec [endicia].[credentialLookup] '588251',@login OUTPUT,@password OUTPUT
SELECT 'login'=@login,'password'=@password

Your code should be contain WHILE before group by and having :

SELECT Email, COUNT(*)

FROM user_log

WHILE Email IS NOT NULL

GROUP BY Email

HAVING COUNT(*) > 1

ORDER BY UpdateDate DESC

This works too, with the semi-colon.

NAME=sam; echo $NAME

The Google Testing Blog discussed this problem recently:

So a naive answer is that writing test carries a 10% tax. But, we pay taxes in order to get something in return.

(snip)

These benefits translate to real value today as well as tomorrow. I write tests, because the additional benefits I get more than offset the additional cost of 10%. Even if I don't include the long term benefits, the value I get from test today are well worth it. I am faster in developing code with test. How much, well that depends on the complexity of the code. The more complex the thing you are trying to build is (more ifs/loops/dependencies) the greater the benefit of tests are.

So one does not have to find and replace the Object.keys method, another approach would be this code early in the execution of the script:

if(!Object.keys)
{
  Object.keys = function(obj)
  {
    return $.map(obj, function(v, k)
    {
      return k;
    });
  };
 }

Add this to method to UIView Category

- (UIImage*) capture {
    UIGraphicsBeginImageContext(self.bounds.size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    [self.layer renderInContext:context];
    UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return img;
}

For localhost on XAMPP. Open a cmd window and type

cd C:\xampp\mysql\bin
mysql.exe -u root -p

Attention! No semi-colon after -p Enter your password and type

use database_name;

to select the database you need.

Check if your table is there

show tables;

Import from your sql file

source sqlfile.sql;

I have put my file on C:\xampp\mysql\bin location in order to don't mix up with locations of sql file.

The CSS code would be:

box-shadow: 0 0 10px 5px white;

That will shadow the entire DIV no matter its shape!

I use this code to costum my bottom navigation item

BottomNavigationView navigation = this.findViewById(R.id.my_bottom_navigation);
Menu menu = navigation.getMenu();
menu.findItem(R.id.nav_wall_see).setTitle("Hello");

For Kotlin and bindings the code is:

binding.spinner.onItemSelectedListener = object : AdapterView.OnItemSelectedListener{
            override fun onNothingSelected(parent: AdapterView<*>?) {
            }

            override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {
            }
        }

Yes, buffering should be used for better performance. Use BufferedReader OR byte[] to store your temp data.

thanks.

Tables displaying the issue:

and ==

Moral of the story use ===

table generation credit: https://github.com/dorey/JavaScript-Equality-Table

I assume that you haven't set the TableName property of the DataTable, for example via constructor:

var tbl = new DataTable("dtImage");

If you don't provide a name, it will be automatically created with "Table1", the next table will get "Table2" and so on.

Then the solution would be to provide the TableName and then check with Contains(nameOfTable).

To clarify it: You'll get an ArgumentException if that DataTable already belongs to the DataSet (the same reference). You'll get a DuplicateNameException if there's already a DataTable in the DataSet with the same name(not case-sensitive).

How about subclassing json.JSONEncoder?

class DecimalEncoder(json.JSONEncoder):
    def default(self, o):
        if isinstance(o, decimal.Decimal):
            # wanted a simple yield str(o) in the next line,
            # but that would mean a yield on the line with super(...),
            # which wouldn't work (see my comment below), so...
            return (str(o) for o in [o])
        return super(DecimalEncoder, self).default(o)

Then use it like so:

json.dumps({'x': decimal.Decimal('5.5')}, cls=DecimalEncoder)

I think cookies might be what you are looking for; this is how most websites uniquely identify visitors.

Use the "has attribute" selector:

$('p[MyTag]')

Or to select one where that attribute has a specific value:

$('p[MyTag="Sara"]')

There are other selectors for "attribute value starts with", "attribute value contains", etc.

I've tried several of the answers here, and I think I have a solution that will work every time and manages permissions as well.

It is based on the clever solution from LEO. This post should contain all the code you need to make this work, and it should work on any phone and Android version ;)

In order to have the ability to pick a file from an SD card, you'll need this in your manifest:

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

Constants:

private static final int PICK_IMAGE = 456; // Whatever number you like
public static final int MY_PERMISSIONS_REQUEST_READ_EXTERNAL = 28528; // Whatever number you like
public static final String FILE_TEMP_NAME = "temp_image"; // Whatever file name you like

Check permission and launchImagePick if possible

if (ContextCompat.checkSelfPermission(getThis(),
        Manifest.permission.READ_EXTERNAL_STORAGE)
        != PackageManager.PERMISSION_GRANTED) {

    ActivityCompat.requestPermissions(getThis(),
            new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
            MY_PERMISSIONS_REQUEST_READ_EXTERNAL);
}
else {
    launchImagePick();
}

Permission response

@Override
public void onRequestPermissionsResult(int requestCode,
                                       @NonNull
                                         String permissions[],
                                       @NonNull
                                         int[] grantResults) {

    if (manageReadExternalPermissionResponse(this, requestCode, grantResults)) {
        launchImagePick();
    }
}

Manage permission response

public static boolean manageReadExternalPermissionResponse(final Activity activity, int requestCode, int[] grantResults) {

    if (requestCode == MY_PERMISSIONS_REQUEST_READ_EXTERNAL) {

        // If request is cancelled, the result arrays are empty.

        if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

            // Permission was granted, yay! Do the
            // contacts-related task you need to do.
            return true;

        } else if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_DENIED) {

            boolean showRationale = ActivityCompat.shouldShowRequestPermissionRationale(activity,
                    Manifest.permission.READ_EXTERNAL_STORAGE);

            if (!showRationale) {
                // The user also CHECKED "never ask again".
                // You can either enable some fall back,
                // disable features of your app
                // or open another dialog explaining
                // again the permission and directing to
                // the app setting.

            } else {
                // The user did NOT check "never ask again".
                // This is a good place to explain the user
                // why you need the permission and ask if he/she wants
                // to accept it (the rationale).
            }
        } else {
            // Permission denied, boo! Disable the
            // functionality that depends on this permission.
        }
    }
    return false;
}

Launch image pick

private void launchImagePick() {

    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/*");
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    startActivityForResult(intent, PICK_IMAGE);

    // see onActivityResult
}

Manage Image pick response

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == PICK_IMAGE) {

        if (resultCode == Activity.RESULT_OK) {
            if (data != null && data.getData() != null) {

                try {
                     InputStream inputStream = getContentResolver().openInputStream(data.getData())
                     if (inputStream != null) {

                        // No special persmission needed to store the file like that
                        FileOutputStream fos = openFileOutput(FILE_TEMP_NAME, Context.MODE_PRIVATE);

                        final int BUFFER_SIZE = 1 << 10 << 3; // 8 KiB buffer
                        byte[] buffer = new byte[BUFFER_SIZE];
                        int bytesRead = -1;
                        while ((bytesRead = inputStream.read(buffer)) > -1) {
                            fos.write(buffer, 0, bytesRead);
                        }
                        inputStream.close();
                        fos.close();

                        File tempImageFile = new File(getFilesDir()+"/"+FILE_TEMP_NAME);

                        // Do whatever you want with the File

                        // Delete when not needed anymore
                        deleteFile(FILE_TEMP_NAME);
                    }
                }
                catch (Exception e) {
                    e.printStackTrace();
                }
            } else {
                // Error display
            }
        } else {
            // The user did not select any image
        }
    }
}

That's all folks; this works for me on all the telephones I have.

I had the same issue but when i deleted the cached items from Temp folder the build failed.

In order to make the build work again I had to close the project and reopen it.

first, you have to create a handler.

var specialElementHandlers = {
    '#editor': function(element, renderer){
        return true;
    }
};

then write this code in click event:

doc.fromHTML($('body').get(0), 15, 15, {
    'width': 170, 
    'elementHandlers': specialElementHandlers
        });

var pdfOutput = doc.output();
            console.log(">>>"+pdfOutput );

assuming you've already declared doc variable. And Then you have save this pdf file using File-Plugin.

The only way that I know that enables you to use ajax cross-domain is JSONP (http://ajaxian.com/archives/jsonp-json-with-padding).

And here's a post that posts some various techniques to achieve cross-domain ajax (http://usejquery.com/posts/9/the-jquery-cross-domain-ajax-guide)

In the Google Maps API v2 Demo there is a MarkerDemoActivity class in which you can see how a custom Image is set to a GoogleMap.

// Uses a custom icon.
mSydney = mMap.addMarker(new MarkerOptions()
    .position(SYDNEY)
    .title("Sydney")
    .snippet("Population: 4,627,300")
    .icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)));

As this just replaces the marker with an image you might want to use a Canvas to draw more complex and fancier stuff:

Bitmap.Config conf = Bitmap.Config.ARGB_8888;
Bitmap bmp = Bitmap.createBitmap(80, 80, conf);
Canvas canvas1 = new Canvas(bmp);

// paint defines the text color, stroke width and size
Paint color = new Paint();
color.setTextSize(35);
color.setColor(Color.BLACK);

// modify canvas
canvas1.drawBitmap(BitmapFactory.decodeResource(getResources(),
    R.drawable.user_picture_image), 0,0, color);
canvas1.drawText("User Name!", 30, 40, color);

// add marker to Map
mMap.addMarker(new MarkerOptions()
    .position(USER_POSITION)
    .icon(BitmapDescriptorFactory.fromBitmap(bmp))
    // Specifies the anchor to be at a particular point in the marker image.
    .anchor(0.5f, 1));

This draws the Canvas canvas1 onto the GoogleMap mMap. The code should (mostly) speak for itself, there are many tutorials out there how to draw a Canvas. You can start by looking at the Canvas and Drawables from the Android Developer page.

Now you also want to download a picture from an URL.

URL url = new URL(user_image_url);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();   
conn.setDoInput(true);   
conn.connect();     
InputStream is = conn.getInputStream();
bmImg = BitmapFactory.decodeStream(is); 

You must download the image from an background thread (you could use AsyncTask or Volley or RxJava for that).

After that you can replace the BitmapFactory.decodeResource(getResources(), R.drawable.user_picture_image) with your downloaded image bmImg.

The Bitmap class is an implementation of the Image class. The Image class is an abstract class;

The Bitmap class contains 12 constructors that construct the Bitmap object from different parameters. It can construct the Bitmap from another bitmap, and the string address of the image.

This will set gravity of your textview.

If you know the number of levels in nested arrays you can simply do nested loops. Like so:

//  Scan through outer loop
foreach ($tmpArray as $innerArray) {
    //  Check type
    if (is_array($innerArray)){
        //  Scan through inner loop
        foreach ($innerArray as $value) {
            echo $value;
        }
    }else{
        // one, two, three
        echo $innerArray;
    }
}

if you do not know the depth of array you need to use recursion. See example below:

//  Multi-dementional Source Array
$tmpArray = array(
    array("one", array(1, 2, 3)),
    array("two", array(4, 5, 6)),
    array("three", array(

Youtube don't provide muting through url parameter (see http://code.google.com/apis/youtube/player_parameters.html).

You have to use javascript for that. see http://code.google.com/apis/youtube/js_api_reference.html for details.

However, please note the warning on the page linked above: "The deprecation of the YouTube JavaScript Player API was announced on January 27, 2015. YouTube Flash embeds have also been deprecated. See the deprecation policy for more information. Please migrate your applications to the IFrame API, which can intelligently use whichever embedded player – HTML () or Flash () – the client supports."

Html

<iframe class="youtube-player" id="player" type="text/html" src="http://www.youtube.com/embed/JW5meKfy3fY?wmode=opaque&autohide=1&autoplay=1&enablejsapi=1" frameborder="0">&lt;br /&gt;</iframe>

please note enablejsapi=1 in the url.

Javascript

var player =  iframe.getElementById('player');
player.mute();

What I normally do, similar to answer one:

var response = await httpClient.GetAsync(completeURL); // http://192.168.0.1:915/api/Controller/Object

if (response.IsSuccessStatusCode == true)
    {
        string res = await response.Content.ReadAsStringAsync();
        var content = Json.Deserialize<Model>(res);

// do whatever you need with the JSON which is in 'content'
// ex: int id = content.Id;

        Navigate();
        return true;
    }
    else
    {
        await JSRuntime.Current.InvokeAsync<string>("alert", "Warning, the credentials you have entered are incorrect.");
        return false;
    }

Where 'model' is your C# model class.

I find the syntax of the previous answers to be redundant and difficult to remember. Pandas introduced the query() method in v0.13 and I much prefer it. For your question, you could do df.query('col == val')

You can also access variables in the environment by prepending an @.

df.query('color not in @exclude')

Faced the same issue post Firefox update to 29.0.1, this is also listed out here https://bugzilla.mozilla.org/show_bug.cgi?id=947728

Solutions: They(Mozilla guys) have fixed this by introducing support for "-moz-appearance" for <input type="number">. You just need to have a style associated with your input field with "-moz-appearance:textfield;".

I prefer the CSS way E.g.:-

.input-mini{
-moz-appearance:textfield;}

Or

You can do it inline as well:

<input type="number" style="-moz-appearance: textfield">

You can also use find() like this:

ModelName::find($id, ['name', 'surname']);

The $id variable can be an array in case you need to retrieve multiple instances of the model.

This is the most important part in the code provided in the original post.

Button one = (Button) this.findViewById(R.id.button1);
final MediaPlayer mp = MediaPlayer.create(this, R.raw.soho);
one.setOnClickListener(new OnClickListener(){

    public void onClick(View v) {
        mp.start();
    }
});

To explain it step by step:

Button one = (Button) this.findViewById(R.id.button1);

First is the initialization of the button to be used in playing the sound. We use the Activity's findViewById, passing the Id we assigned to it (in this example's case: R.id.button1), to get the button that we need. We cast it as a Button so that it is easy to assign it to the variable one that we are initializing. Explaining more of how this works is out of scope for this answer. This gives a brief insight on how it works.

final MediaPlayer mp = MediaPlayer.create(this, R.raw.soho);

This is how to initialize a MediaPlayer. The MediaPlayer follows the Static Factory Method Design Pattern. To get an instance, we call its create() method and pass it the context and the resource Id of the sound we want to play, in this case R.raw.soho. We declare it as final. Jon Skeet provided a great explanation on why we do so here.

one.setOnClickListener(new OnClickListener(){

    public void onClick(View v) {
        //code
    }
});

Finally, we set what our previously initialized button will do. Play a sound on button click! To do this, we set the OnClickListener of our button one. Inside is only one method, onClick() which contains what instructions the button should do on click.

public void onClick(View v) {
    mp.start();
}

To play the sound, we call MediaPlayer's start() method. This method starts the playback of the sound.

There, you can now play a sound on button click in Android!

Bonus part:

As noted in the comment below^{Thanks Langusten Gustel!}, and as recommended in the Android Developer Reference, it is important to call the release() method to free up resources that will no longer be used. Usually, this is done once the sound to be played has completed playing. To do so, we add an OnCompletionListener to our mp like so:

mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
    public void onCompletion(MediaPlayer mp) {
        //code
    }
});

Inside the onCompletion method, we release it like so:

public void onCompletion(MediaPlayer mp) {
    mp.release();
}

There are obviously better ways of implementing this. For example, you can make the MediaPlayer a class variable and handle its lifecycle along with the lifecycle of the Fragment or Activity that uses it. However, this is a topic for another question. To keep the scope of this answer small, I wrote it just to illustrate how to play a sound on button click in Android.

Original Post

First. You should put your statements inside a block, and in this case the onCreate method.

Second. You initialized the button as variable one, then you used a variable zero and set its onClickListener to an incomplete onClickListener. Use the variable one for the setOnClickListener.

Third, put the logic to play the sound inside the onClick.

In summary:

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class BasicScreenActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {        
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_basic_screen);

        Button one = (Button)this.findViewById(R.id.button1);
        final MediaPlayer mp = MediaPlayer.create(this, R.raw.soho);
        one.setOnClickListener(new OnClickListener(){

            public void onClick(View v) {
                mp.start();
            }
        });
    }
}

One of my concerns with phpMyAdmin was that by default, all MySQL users can access the db. If DB's root password is compromised, someone can wreck havoc on the db. I wanted to find a way to avoid that by restricting which MySQL user can login to phpMyAdmin.

I have found using AllowDeny configuration in PhpMyAdmin to be very useful. http://wiki.phpmyadmin.net/pma/Config#AllowDeny_.28rules.29

AllowDeny lets you configure access to phpMyAdmin in a similar way to Apache. If you set the 'order' to explicit, it will only grant access to users defined in 'rules' section. In the rules, section you restrict MySql users who can access use the phpMyAdmin.

$cfg['Servers'][$i]['AllowDeny']['order'] = 'explicit'
$cfg['Servers'][$i]['AllowDeny']['rules'] = array('pma-user from all')

Now you have limited access to the user named pma-user in MySQL, you can grant limited privilege to that user.

grant select on db_name.some_table to 'pma-user'@'app-server'

For windows 8.1 & python 2.7 , I fixed the problem by following below steps

1 . Download and install graphviz-2.38.msi http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.38.msi

2 . Set the path variable

• Control Panel > System and Security > System > Advanced System Settings > Environment Variables > Path > Edit
• add 'C:\Program Files (x86)\Graphviz2.38\bin'

Using Android Studio (current version is 2.2.2 at moment) is very easy to add a fullscreen activity.

See the steps:

1. Right click on your java main package > Select “New” > Select “Activity” > Then, click on “Fullscreen Activity”.

2. Customize the activity (“Activity Name”, “Layout Name” and so on) and click “finish”.

Done!

Now you have a fullscreen activity made easily (see the java class and the activity layout to know how the things works)!

This is not only a 'newbie' scenario. I just ran across this compiler message (GCC 5.4) when refactoring a class to remove some constructor parameters. I forgot to update both the declaration and definition, and the compiler spit out this unintuitive error.

The bottom line seems to be this: If the compiler can't match the definition's signature to the declaration's signature it thinks the definition is not a constructor and then doesn't know how to parse the code and displays this error. Which is also what happened for the OP: std::string is not the same type as string so the declaration's signature differed from the definition's and this message was spit out.

As a side note, it would be nice if the compiler looked for almost-matching constructor signatures and upon finding one suggested that the parameters didn't match rather than giving this message.

Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming

Update March 2013

Git 1.8.2 added the possibility to track branches.

"git submodule" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).

# add submodule to track master branch
git submodule add -b master [URL to Git repo];

# update your submodule
git submodule update --remote 

If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".

Also see Vogella's tutorial on submodules for general information on submodules.

Note:

git submodule add -b . [URL to Git repo];
                    ^^^

See git submodule man page:

A special value of . is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.

See commit b928922727d6691a3bdc28160f93f25712c565f6:

submodule add: If --branch is given, record it in .gitmodules

This allows you to easily record a submodule.<name>.branch option in .gitmodules when you add a new submodule. With this patch,

$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>

reduces to

$ git submodule add -b <branch> <repository> [<path>]

This means that future calls to

$ git submodule update --remote ...

will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):

A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log within that submodule.

So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:

• cd in the submodule
• git fetch/pull to make sure it has the latest commits on the right branch
• cd back in the parent repo
• add and commit in order to record the new commit of the submodule.

gitslave (that you already looked at) seems to be the best fit, including for the commit operation.

It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).

Other alternatives are detailed here.

I think you may be confusing Javascript with jQuery methods. Vanilla or plain Javascript is something like:

function example() {
}

A function of that nature can be called at any time, anywhere.

jQuery (a library built on Javascript) has built in functions that generally required the DOM to be fully rendered before being called. The syntax for when this is completed is:

$(document).ready(function() {
});

So a jQuery function, which is prefixed with the $ or the word jQuery generally is called from within that method.

$(document).ready(function() {        
    // Assign all list items on the page to be the  color red.  
    //      This does not work until AFTER the entire DOM is "ready", hence the $(document).ready()
    $('li').css('color', 'red');   
});

The pseudo-code for that block is:

When the document object model $(document) is ready .ready(), call the following function function() { }. In that function, check for all <li>'s on the page $('li') and using the jQuery method .CSS() to set the CSS property "color" to the value "red" .css('color', 'red');

You can just add these code in AppServiceProvider class boot method.

Blade::extend(function($value, $compiler){
        $value = preg_replace('/(\s*)@switch\((.*)\)(?=\s)/', '$1<?php switch($2):', $value);
        $value = preg_replace('/(\s*)@endswitch(?=\s)/', '$1endswitch; ?>', $value);
        $value = preg_replace('/(\s*)@case\((.*)\)(?=\s)/', '$1case $2: ?>', $value);
        $value = preg_replace('/(?<=\s)@default(?=\s)/', 'default: ?>', $value);
        $value = preg_replace('/(?<=\s)@breakswitch(?=\s)/', '<?php break;', $value);
        return $value;
    });

then you can use as:

@switch( $item )
    @case( condition_1 )
        // do something
    @breakswitch
    @case( condition_2 )
        // do something else
    @breakswitch
    @default
        // do default behaviour
    @breakswitch
@endswitch

Enjoy It~

My apt-get was old and busted, so I had to install from source. Here is what worked for me:

# Get the latest version from nodejs.org. At the time of this writing, it was 0.10.24
curl -o ~/node.tar.gz http://nodejs.org/dist/v0.10.24/node-v0.10.24.tar.gz
cd
tar -zxvf node.tar.gz
cd node-v0.6.18
./configure && make && sudo make install

These steps were mostly taken from joyent's installation wiki.

Expanding on the answers provided here.

You can just do set idx = 1 to set a variable, but that syntax is not recommended because the variable name may clash with a set sub-command. As an example set w=1 would not be valid.

This means that you should prefer the syntax: set variable idx = 1 or set var idx = 1.

Last but not least, you can just use your trusty old print command, since it evaluates an expression. The only difference being that he also prints the result of the expression.

(gdb) p idx = 1
$1 = 1

You can read more about gdb here.

You can try this

 $('div.easy_editor').css({'border-width':'9px', 'border-style':'solid', 'border-color':'red'});

The $('div.easy_editor') refers to a collection of all divs that have the class easy editor already. There is no need to use each() unless there was some function that you wanted to run on each. The css() method actually applies to all the divs you find.

First of all open command prompt then open bin directory in cmd (i hope you're aware with cmd commands) go to bin directory of your MySql folder in WAMP program files.

run command

mysqldump -u db_username -p database_name > path_where_to_save_sql_file

press enter system will export particular database and create sql file to the given location.

i hope you got it :) if you have any question please let me know.

Unfortunately, modern browsers do not provide native support for HTTP PUT requests. To work around this limitation, ensure your HTML form’s method attribute is “post”, then add a method override parameter to your HTML form like this:

<input type="hidden" name="_METHOD" value="PUT"/>

To test your requests you can use "Postman" a google chrome extension

From the official Array Apple documentation:

init(_:) - Creates an array containing the elements of a sequence.

Declaration

Array.init<S>(_ s: S) where Element == S.Element, S : Sequence

Parameters

s - The sequence of elements to turn into an array.

Discussion

You can use this initializer to create an array from any other type that conforms to the Sequence protocol...You can also use this initializer to convert a complex sequence or collection type back to an array. For example, the keys property of a dictionary isn’t an array with its own storage, it’s a collection that maps its elements from the dictionary only when they’re accessed, saving the time and space needed to allocate an array. If you need to pass those keys to a method that takes an array, however, use this initializer to convert that list from its type of LazyMapCollection<Dictionary<String, Int>, Int> to a simple [String].

func cacheImagesWithNames(names: [String]) {
    // custom image loading and caching
 }

let namedHues: [String: Int] = ["Vermillion": 18, "Magenta": 302,
        "Gold": 50, "Cerise": 320]
let colorNames = Array(namedHues.keys)
cacheImagesWithNames(colorNames)

print(colorNames)
// Prints "["Gold", "Cerise", "Magenta", "Vermillion"]"

For you Windows XP users (who have no where command built-in), I have written a "where like" command as a rubygem called whichr.

To install it, install Ruby.

Then

gem install whichr

Run it like:

                string BaseWindow = driver.CurrentWindowHandle;
                ReadOnlyCollection<string> handles = driver.WindowHandles;

    else
    {
        int val = GetID(entity);
        var entry = GetEntryAsync(context, GetID(entity)).ConfigureAwait(false);
        context.Entry(entry).CurrentValues.SetValues(entity);

    }
    
    await context.SaveChangesAsync().ConfigureAwait(false);
}

This was in an async method, but I've forgot to put await before GetEntryAsync, and so I got this same error...

I assume you're asking about combinations in combinatorial sense (that is, order of elements doesn't matter, so [1 2 3] is the same as [2 1 3]). The idea is pretty simple then, if you understand induction / recursion: to get all K-element combinations, you first pick initial element of a combination out of existing set of people, and then you "concatenate" this initial element with all possible combinations of K-1 people produced from elements that succeed the initial element.

As an example, let's say we want to take all combinations of 3 people from a set of 5 people. Then all possible combinations of 3 people can be expressed in terms of all possible combinations of 2 people:

comb({ 1 2 3 4 5 }, 3) =
{ 1, comb({ 2 3 4 5 }, 2) } and
{ 2, comb({ 3 4 5 }, 2) } and
{ 3, comb({ 4 5 }, 2) }

Here's C++ code that implements this idea:

#include <iostream>
#include <vector>

using namespace std;

vector<int> people;
vector<int> combination;

void pretty_print(const vector<int>& v) {
  static int count = 0;
  cout << "combination no " << (++count) << ": [ ";
  for (int i = 0; i < v.size(); ++i) { cout << v[i] << " "; }
  cout << "] " << endl;
}

void go(int offset, int k) {
  if (k == 0) {
    pretty_print(combination);
    return;
  }
  for (int i = offset; i <= people.size() - k; ++i) {
    combination.push_back(people[i]);
    go(i+1, k-1);
    combination.pop_back();
  }
}

int main() {
  int n = 5, k = 3;

  for (int i = 0; i < n; ++i) { people.push_back(i+1); }
  go(0, k);

  return 0;
}

And here's output for N = 5, K = 3:

combination no 1:  [ 1 2 3 ] 
combination no 2:  [ 1 2 4 ] 
combination no 3:  [ 1 2 5 ] 
combination no 4:  [ 1 3 4 ] 
combination no 5:  [ 1 3 5 ] 
combination no 6:  [ 1 4 5 ] 
combination no 7:  [ 2 3 4 ] 
combination no 8:  [ 2 3 5 ] 
combination no 9:  [ 2 4 5 ] 
combination no 10: [ 3 4 5 ] 

I suppose you could use a DataView object instead, this would then allow you to take advantage of the RowFilter property as explained here:

http://msdn.microsoft.com/en-us/library/system.data.dataview.rowfilter.aspx

private void MakeDataView() 
{
    DataView view = new DataView();

    view.Table = DataSet1.Tables["Countries"];
    view.RowFilter = "CountryName = 'France'";
    view.RowStateFilter = DataViewRowState.ModifiedCurrent;

    // Simple-bind to a TextBox control
    Text1.DataBindings.Add("Text", view, "CountryID");
}

You can stash (save the changes in temporary box) then, back to master branch HEAD.

$ git add .
$ git stash
$ git checkout master

Jump Over Commits Back and Forth:

• Go to a specific commit-sha.

    $ git checkout <commit-sha>
  

• If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.

    # checkout a new branch, add, commit, push
    $ git checkout -b <branch-name>
    $ git add .
    $ git commit -m 'Commit message'
    $ git push origin HEAD          # push the current branch to remote 
  
    $ git checkout master           # back to master branch now
  

• If you have changes in the specific commit and don't want to keep the changes, you can do stash or reset then checkout to master (or, any other branch).

    # stash
    $ git add -A
    $ git stash
    $ git checkout master
  
    # reset
    $ git reset --hard HEAD
    $ git checkout master
  

• After checking out a specific commit if you have no uncommitted change(s) then, just back to master or other branch.

    $ git status          # see the changes
    $ git checkout master
  
    # or, shortcut
    $ git checkout -      # back to the previous state
  

For django forms you can do this;

form = UserLoginForm(data=request.POST) #getting the whole data from the user.
user = form.save() #saving the details obtained from the user.
username = user.cleaned_data.get("username") #where "username" in parenthesis is the name of the Charfield (the variale name i.e, username = forms.Charfield(max_length=64))

They do different things. exec replaces the current process with the new process and never returns. system invokes another process and returns its exit value to the current process. Using backticks invokes another process and returns the output of that process to the current process.

one thing need to mention on @LachlanB 's answer.

protected void Application_PostAuthorizeRequest()
    {
        if (IsWebApiRequest())
        {
            HttpContext.Current.SetSessionStateBehavior(SessionStateBehavior.Required);
        }
    }

If you omit the line if (IsWebApiRequest())

The whole site will have page loading slowness issue if your site is mixed with web form pages.

you have to use the To_Date() function to convert the string to date ! http://www.techonthenet.com/oracle/functions/to_date.php

Range("A1").value = Environ("Username")

This is better than Application.Username, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.

• Application Username is the name of the User set in Excel > Tools > Options
• Environ("Username") is the name you registered for Windows; see Control Panel >System

You need to either have the message be a fixed size, or you need to send the size or you need to use some separator characters.

This is the easiest case for a known size (100 bytes):

in = new DataInputStream(server.getInputStream());
byte[] message = new byte[100]; // the well known size
in.readFully(message);

In this case DataInputStream makes sense as it offers readFully(). If you don't use it, you need to loop yourself until the expected number of bytes is read.

It's used to add padding in UIScrollView

Without contentInset, a table view is like this:

Then set contentInset:

tableView.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 0, right: 0)

The effect is as below:

Seems to be better, right?

And I write a blog to study the contentInset, criticism is welcome.

Python Force-suppress all exponential notation when printing numpy ndarrays, wrangle text justification, rounding and print options:

What follows is an explanation for what is going on, scroll to bottom for code demos.

Passing parameter suppress=True to function set_printoptions works only for numbers that fit in the default 8 character space allotted to it, like this:

import numpy as np
np.set_printoptions(suppress=True) #prevent numpy exponential 
                                   #notation on print, default False

#            tiny     med  large
a = np.array([1.01e-5, 22, 1.2345678e7])  #notice how index 2 is 8 
                                          #digits wide

print(a)    #prints [ 0.0000101   22.     12345678. ]

However if you pass in a number greater than 8 characters wide, exponential notation is imposed again, like this:

np.set_printoptions(suppress=True)

a = np.array([1.01e-5, 22, 1.2345678e10])    #notice how index 2 is 10
                                             #digits wide, too wide!

#exponential notation where we've told it not to!
print(a)    #prints [1.01000000e-005   2.20000000e+001   1.23456780e+10]

numpy has a choice between chopping your number in half thus misrepresenting it, or forcing exponential notation, it chooses the latter.

Here comes set_printoptions(formatter=...) to the rescue to specify options for printing and rounding. Tell set_printoptions to just print bare a bare float:

np.set_printoptions(suppress=True,
   formatter={'float_kind':'{:f}'.format})

a = np.array([1.01e-5, 22, 1.2345678e30])  #notice how index 2 is 30
                                           #digits wide.  

#Ok good, no exponential notation in the large numbers:
print(a)  #prints [0.000010 22.000000 1234567799999999979944197226496.000000] 

We've force-suppressed the exponential notation, but it is not rounded or justified, so specify extra formatting options:

np.set_printoptions(suppress=True,
   formatter={'float_kind':'{:0.2f}'.format})  #float, 2 units 
                                               #precision right, 0 on left

a = np.array([1.01e-5, 22, 1.2345678e30])   #notice how index 2 is 30
                                            #digits wide

print(a)  #prints [0.00 22.00 1234567799999999979944197226496.00]

The drawback for force-suppressing all exponential notion in ndarrays is that if your ndarray gets a huge float value near infinity in it, and you print it, you're going to get blasted in the face with a page full of numbers.

Notice that rounding is consistent at 2 units precision, and exponential notation is suppressed in both the very large e+x and very small e-x ranges.

The way you have added a row into the table layout you can add multiple TableRow instances into your tableLayout object

tl.addView(row1);
tl.addView(row2);

etc...

It depends on what type of machine/encoding generated your import file.

If you're getting it from an English or Western European version of Windows, your best bet is probably setting it to 'WIN1252'. If you are getting it from a different source, consult the list of character encodings here:

http://www.postgresql.org/docs/8.3/static/multibyte.html

If you're getting it from a Mac, you may have to run it through the "iconv" utility first to convert it from MacRoman to UTF-8.

Try this:

if cookie and not cookie.isspace():
    # the string is non-empty
else:
    # the string is empty

The above takes in consideration the cases where the string is None or a sequence of white spaces.

To complete Sunit's answer, you can use a selector, not to the text string but to the textColorHint. You must add this attribute on your editText:

android:textColorHint="@color/text_hint_selector"

And your text_hint_selector should be:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:color="@android:color/transparent" />
    <item android:color="@color/hint_color" />
</selector>

BCrypt is a very good library, and there is a Java port of it.

I got the same problem, the solution is add the property data-dismiss="modal" to the button you are going to click.

If the project is maven placed it in src/main/resources, in the package phase it will copy it in ../WEB-INF/classes/hibernate.cfg.xml

Be sure to have both objects created in controller: @post and @comment for the post, eg:

@post = Post.find params[:post_id]
@comment = Comment.new(:post=>@post)

Then in view:

<%= form_for([@post, @comment]) do |f| %>

Be sure to explicitly define the array in the form_for, not just comma separated like you have above.

Handy one-liners

for D in *; do echo "$D"; done
for D in *; do find "$D" -type d; done ### Option A

find * -type d ### Option B

Option A is correct for folders with spaces in between. Also, generally faster since it doesn't print each word in a folder name as a separate entity.

# Option A
$ time for D in ./big_dir/*; do find "$D" -type d > /dev/null; done
real    0m0.327s
user    0m0.084s
sys     0m0.236s

# Option B
$ time for D in `find ./big_dir/* -type d`; do echo "$D" > /dev/null; done
real    0m0.787s
user    0m0.484s
sys     0m0.308s

just put as your last line of code:

system("pause");

This will definitely work for you.

android:windowSoftInputMode="adjustPan"

I know this is an old question that has an answer already, and there are a number of other decent answers. I see some answers that propose that you can solve this problem by looking up the correct insertion index in O(log n) - you can, but you can't insert in that time, because the array needs to be partially copied out to make space.

Bottom line: If you really need O(log n) inserts and deletes into a sorted array, you need a different data structure - not an array. You should use a B-Tree. The performance gains you will get from using a B-Tree for a large data set, will dwarf any of the improvements offered here.

If you must use an array. I offer the following code, based on insertion sort, which works, if and only if the array is already sorted. This is useful for the case when you need to resort after every insert:

function addAndSort(arr, val) {
    arr.push(val);
    for (i = arr.length - 1; i > 0 && arr[i] < arr[i-1]; i--) {
        var tmp = arr[i];
        arr[i] = arr[i-1];
        arr[i-1] = tmp;
    }
    return arr;
}

It should operate in O(n), which I think is the best you can do. Would be nicer if js supported multiple assignment. here's an example to play with:

Update:

this might be faster:

function addAndSort2(arr, val) {
    arr.push(val);
    i = arr.length - 1;
    item = arr[i];
    while (i > 0 && item < arr[i-1]) {
        arr[i] = arr[i-1];
        i -= 1;
    }
    arr[i] = item;
    return arr;
}

I have problem running the py files in my java code using eclipse/STS, getting PyException due to insufficient jvm heap memory. I have done the changes as mentioned below and I'm able to resolve this issue. Below is my System configuration.

And these are the changes I did in my workspace and voila it runs perfect now.

You could use the or operator:

return x or "default"

Note that this also returns "default" if x is any falsy value, including an empty list, 0, empty string, or even datetime.time(0) (midnight).

From your referenced page:

http://googlecode.blogspot.com/2009/12/google-analytics-launches-asynchronous.html

Firefox 3.6 is the first browser to officially offer support for this new feature. If you're curious, here are more details on the official HTML5 async specification.

You should be using where, select is a projection that returns the output of the statement, thus why you get boolean values. where is a filter that keeps the structure of the dataframe, but only keeps data where the filter works.

Along the same line though, per the documentation, you can write this in 3 different ways

// The following are equivalent:
peopleDf.filter($"age" > 15)
peopleDf.where($"age" > 15)
peopleDf($"age" > 15)

A (partial) practical work-around is to put things into a throw-away function.

Pasting

x = 1
x += 1
print(x)

results in

>>> x = 1
x += 1
print(x)
  File "<stdin>", line 1
    x += 1
print(x)

    ^
SyntaxError: multiple statements found while compiling a single statement
>>>

However, pasting

def abc():
  x = 1
  x += 1
  print(x)

works:

>>> def abc():
  x = 1
  x += 1
  print(x)
>>> abc()
2
>>>

Of course, this is OK for a quick one-off, won't work for everything you might want to do, etc. But then, going to ipython / jupyter qtconsole is probably the next simplest option.

I had the same problem when I was running the plotting commands in separate cells in Jupyter:

In [1]:  %matplotlib inline
         import matplotlib
         import matplotlib.pyplot as plt
         import numpy as np
In [2]:  x = np.array([1, 3, 4])
         y = np.array([1, 5, 3])
In [3]:  fig = plt.figure()
         <Figure size 432x288 with 0 Axes>                      #this might be the problem
In [4]:  ax = fig.add_subplot(1, 1, 1)
In [5]:  ax.scatter(x, y)
Out[5]:  <matplotlib.collections.PathCollection at 0x12341234>  # CAN'T SEE ANY PLOT :(
In [6]:  plt.show()                                             # STILL CAN'T SEE IT :(

The problem was solved by merging the plotting commands into a single cell:

In [1]:  %matplotlib inline
         import matplotlib
         import matplotlib.pyplot as plt
         import numpy as np
In [2]:  x = np.array([1, 3, 4])
         y = np.array([1, 5, 3])
In [3]:  fig = plt.figure()
         ax = fig.add_subplot(1, 1, 1)
         ax.scatter(x, y)
Out[3]:  <matplotlib.collections.PathCollection at 0x12341234>
         # AND HERE APPEARS THE PLOT AS DESIRED :)

IE11 uses an older version of the Grid specification.

The properties you are using don't exist in the older grid spec. Using prefixes makes no difference.

Here are three problems I see right off the bat.

repeat()

The repeat() function doesn't exist in the older spec, so it isn't supported by IE11.

You need to use the correct syntax, which is covered in another answer to this post, or declare all row and column lengths.

Instead of:

.grid {
  display: -ms-grid;
  display: grid;
  -ms-grid-columns: repeat( 4, 1fr );
      grid-template-columns: repeat( 4, 1fr );
  -ms-grid-rows: repeat( 4, 270px );
      grid-template-rows: repeat( 4, 270px );
  grid-gap: 30px;
}

Use:

.grid {
  display: -ms-grid;
  display: grid;
  -ms-grid-columns: 1fr 1fr 1fr 1fr;             /* adjusted */
      grid-template-columns:  repeat( 4, 1fr );
  -ms-grid-rows: 270px 270px 270px 270px;        /* adjusted */
      grid-template-rows: repeat( 4, 270px );
  grid-gap: 30px;
}

Older spec reference: https://www.w3.org/TR/2011/WD-css3-grid-layout-20110407/#grid-repeating-columns-and-rows

span

The span keyword doesn't exist in the older spec, so it isn't supported by IE11. You'll have to use the equivalent properties for these browsers.

Instead of:

.grid .grid-item.height-2x {
  -ms-grid-row: span 2;
      grid-row: span 2;
}
.grid .grid-item.width-2x {
  -ms-grid-column: span 2;
      grid-column: span 2;
}

Use:

.grid .grid-item.height-2x {
  -ms-grid-row-span: 2;          /* adjusted */
      grid-row: span 2;
}
.grid .grid-item.width-2x {
  -ms-grid-column-span: 2;       /* adjusted */
      grid-column: span 2;
}

Older spec reference: https://www.w3.org/TR/2011/WD-css3-grid-layout-20110407/#grid-row-span-and-grid-column-span

grid-gap

The grid-gap property, as well as its long-hand forms grid-column-gap and grid-row-gap, don't exist in the older spec, so they aren't supported by IE11. You'll have to find another way to separate the boxes. I haven't read the entire older spec, so there may be a method. Otherwise, try margins.

grid item auto placement

There was some discussion in the old spec about grid item auto placement, but the feature was never implemented in IE11. (Auto placement of grid items is now standard in current browsers).

So unless you specifically define the placement of grid items, they will stack in cell 1,1.

Use the -ms-grid-row and -ms-grid-column properties.

• CSS Grid auto placement in IE/EDGE
• CSS Grid not working in ie11 despite prefixes
• https://www.w3.org/TR/2011/WD-css3-grid-layout-20110407/#automatic-placement-of-grid-items

The Content-Type header is just used as info for your application. The browser doesn't care what it is. The browser just returns you the data from the AJAX call. If you want to parse it as JSON, you need to do that on your own.

The header is there so your app can detect what data was returned and how it should handle it. You need to look at the header, and if it's application/json then parse it as JSON.

This is actually how jQuery works. If you don't tell it what to do with the result, it uses the Content-Type to detect what to do with it.

How I redirect to an area is add it as a parameter

@Html.Action("Action", "Controller", new { area = "AreaName" })

for the href portion of a link I use

@Url.Action("Action", "Controller", new { area = "AreaName" })

i called activity_name.this.finish() after starting new intent and it worked for me.

I tried "FLAG_ACTIVITY_CLEAR_TOP" and "FLAG_ACTIVITY_NEW_TASK"

But it won't work for me... I am not suggesting this solution for use but if setting flag won't work for you than you can try this..But still i recommend don't use it

A little more elegant way of doing the same adding on to the above comment ..

<asp:GridView ID="grdParent" runat="server" BackColor="White" BorderColor="#DEDFDE"
                           AutoGenerateColumns="false"
                            OnRowDeleting="deleteRow"
                         GridLines="Vertical">
      <asp:BoundField DataField="IdTemplate" HeaderText="IdTemplate" />
      <asp:BoundField DataField="EntityId" HeaderText="EntityId"  />
    <asp:TemplateField ShowHeader="false">
        <ItemTemplate>
           <asp:LinkButton ID="lnkCustomize" Text="Delete"  CommandName="Delete"  CommandArgument='<%#Eval("IdTemplate") + ";" +Eval("EntityId")%>'  runat="server"> 
           </asp:LinkButton>   
        </ItemTemplate>   
    </asp:TemplateField>
     </asp:GridView>

And on the server side:

protected void deleteRow(object sender, GridViewDeleteEventArgs e)
{
    string IdTemplate= e.Values["IdTemplate"].ToString();
    string EntityId = e.Values["EntityId"].ToString();

   // Do stuff..
}

You can also get this error if you try to include a jar which was compiled with jdk 1.7 instead of 1.6.

In my case, I figured this out by trying to package my app with the Ant scripts provided by the SDK, instead of ADT, and I noticed these errors, which ADT did not show me:

  [dex] Pre-Dexing libjingle_peerconnection.jar -> libjingle_peerconnection-2f82c9bf868a6c58eaf2c3b2fe6a09f3.jar
   [dx]
   [dx] trouble processing:
   [dx] bad class file magic (cafebabe) or version (0033.0000)
   [dx] ...while parsing org/webrtc/StatsReport$Value.class
   [dx] ...while processing org/webrtc/StatsReport$Value.class

I recompiled my jar with jdk 1.6 and the error was fixed.

There are 2 ways in which you can get the values:-

1. Access the property of the object using dot notation (obj.property) .
2. Access the property of the object by passing in key value for example obj["property"]

Use where with a != operator in combination with whereNull

Code::where('to_be_used_by_user_id', '!=' , 2)->orWhereNull('to_be_used_by_user_id')->get()

If you using the node-mysql module, just remove the .connect and .end. Just solved the problem myself. Apparently they pushed in unnecessary code in their last iteration that is also bugged. You don't need to connect if you have already ran the createConnection call

Just as an FYI - "best" questions aren't the norm at SO, but I will give you a list of options, just as a service.

OK then. These two are the ones I used:

Komodo Edit

Aptana Studio 3

and then there is always Eclipse.

*UPDATE 20 March 2013 *

Well, Sublime Text 2 is the one to heavily consider. Heavily.

Use the below code for a setup session cookie, it will work until browser close. (make sure not close tab)

function setCookie(cname, cvalue, exdays) {
    var d = new Date();
    d.setTime(d.getTime() + (exdays*24*60*60*1000));
    var expires = "expires="+ d.toUTCString();
    document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
  }
  function getCookie(cname) {
    var name = cname + "=";
    var decodedCookie = decodeURIComponent(document.cookie);
    var ca = decodedCookie.split(';');
    for(var i = 0; i <ca.length; i++) {
      var c = ca[i];
      while (c.charAt(0) == ' ') {
        c = c.substring(1);
      }
      if (c.indexOf(name) == 0) {
        return c.substring(name.length, c.length);
      }
    }
    return false;
  }
  
  
  if(getCookie("KoiMilGaya")) {
    //alert('found'); 
    // Cookie found. Display any text like repeat user. // reload, other page visit, close tab and open again.. 
  } else {
    //alert('nothing');
    // Display popup or anthing here. it shows on first visit only.  
    // this will load again when user closer browser and open again. 
    setCookie('KoiMilGaya','1');
  }

If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".

Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".

Because that's not what strip() does. It removes leading and trailing characters that are present in the argument, but not those characters in the middle of the string.

You could do:

name= name.replace('(', '').replace(')', '').replace ...

or:

name= ''.join(c for c in name if c not in '(){}<>')

or maybe use a regex:

import re
name= re.sub('[(){}<>]', '', name)

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });

Here's the answer

Steps to follow:

1. Open the Visual Basic Editor. In Excel, hit Alt+F11 if on Windows, Fn+Option+F11 if on a Mac.

2. Insert a new module. From the menu: Insert -> Module (Don't skip this!).

3. Create a Public function. Example:

   Public Function findArea(ByVal width as Double, _
                            ByVal height as Double) As Double
       ' Return the area
       findArea = width * height
   End Function
   

4. Then use it in any cell like you would any other function: =findArea(B12,C12).

Jar File in the system path is:

C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib\ojdbc14.jar

ojdbc14.jar(it's jar file)

1. Right-click on your project
2. Select Build Path
3. Click on Configure Build Path
4. Click on Libraries, select Modulepath and select Add External JARs
5. Select the jar file from the required folder

For me, I just wanted to test a website that had an automatic http->https redirect. I think I had some certs installed already, so this alone works for me on Ubuntu 16.04 running curl 7.47.0 (x86_64-pc-linux-gnu) libcurl/7.47.0 GnuTLS/3.4.10 zlib/1.2.8 libidn/1.32 librtmp/2.3

curl --proto-default https <target>

iif has always been available in VB, even in VB6.

Dim foo as String = iif(bar = buz, cat, dog)

It is not a true operator, as such, but a function in the Microsoft.VisualBasic namespace.

If you have changed files you don't want to lose, you can push them. I have committed them in the detached mode and after that you can move to a temporary branch to integrate later in master.

git commit -m "....."
git branch my-temporary-work
git checkout master
git merge my-temporary-work
