Since Mar 2017: With the addition of Firebase Cloud Functions, and Firebase's deeper integration with Google Cloud, this is now possible.
With Cloud Functions you can use the Google Cloud Node package to do epic operations on Cloud Storage. Below is an example that gets all the file URLs into an array from Cloud Storage. This function will be triggered every time something's saved to google cloud storage.
Note 1: This is a rather computationally expensive operation, as it has to cycle through all files in a bucket / folder.
Note 2: I wrote this just as an example, without paying much detail into promises etc. Just to give an idea.
const functions = require('firebase-functions');
const gcs = require('@google-cloud/storage')();
// let's trigger this function with a file upload to google cloud storage
exports.fileUploaded = functions.storage.object().onChange(event => {
const object = event.data; // the object that was just uploaded
const bucket = gcs.bucket(object.bucket);
const signedUrlConfig = { action: 'read', expires: '03-17-2025' }; // this is a signed url configuration object
var fileURLs = []; // array to hold all file urls
// this is just for the sake of this example. Ideally you should get the path from the object that is uploaded :)
const folderPath = "a/path/you/want/its/folder/size/calculated";
bucket.getFiles({ prefix: folderPath }, function(err, files) {
// files = array of file objects
// not the contents of these files, we're not downloading the files.
files.forEach(function(file) {
file.getSignedUrl(signedUrlConfig, function(err, fileURL) {
console.log(fileURL);
fileURLs.push(fileURL);
});
});
});
});
I hope this will give you the general idea. For better cloud functions examples, check out Google's Github repo full of Cloud Functions samples for Firebase. Also check out their Google Cloud Node API Documentation
Look up NR
and FNR
in the awk manual and then ask yourself what is the condition under which NR==FNR
in the following example:
$ cat file1
a
b
c
$ cat file2
d
e
$ awk '{print FILENAME, NR, FNR, $0}' file1 file2
file1 1 1 a
file1 2 2 b
file1 3 3 c
file2 4 1 d
file2 5 2 e
If you're using Swift, it's as simple as:
subviews.map { $0.removeFromSuperview }
It's similar in philosophy to the makeObjectsPerformSelector
approach, however with a little more type safety.
$fruit = array('apple', 'banana', 'pear', 'grape');
$commasaprated = implode(',' , $fruit);
Merger two image png and jpg/png [Image Masking]
//URL or Local path

//if you want to make same size
list($width, $height) = getimagesize($dest_url);
list($newWidth, $newHeight) = getimagesize($src_url);
$dest = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($dest, $dest1, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);
list($src_w, $src_h) = getimagesize($src_url);

To confirm you video is in the correct format (resolution, bitrate, codec, etc.) check with the official documentation - extract below:
Standard definition (Low quality)
Video codec - H.264
Video resolution - 176 x 144 px
Video frame rate - 12 fps
Video bitrate - 56 Kbps
Audio codec - AAC-LC
Audio channels - (mono)
Audio bitrate - 24 Kbps
Standard definition (High quality)
Video codec - H.264
Video resolution - 480 x 360 px
Video frame rate - 30 fps
Video bitrate - 500 Kbps
Audio codec - AAC-LC
Audio channels - 2 (stereo)
Audio bitrate - 128 Kbps
High definition 720p (N/A on all devices)
Video codec - H.264
Video resolution - 1280 x 720 px
Video frame rate - 30 fps
Video bitrate - 2 Mbps
Audio codec - AAC-LC
Audio channels - 2 (stereo)
Audio bitrate - 192 Kbps
If you want to use standard extra data field, you would do something like this:
private Uri imageUri;
....
Intent intent = new Intent(this, GoogleActivity.class);
intent.putExtra(Intent.EXTRA_STREAM, imageUri.toString());
startActivity(intent);
this.finish();
The documentation for Intent says:
EXTRA_STREAM added in API level 1
String EXTRA_STREAM
A content: URI holding a stream of data associated with the Intent,
used with ACTION_SEND to supply the data being sent.
Constant Value: "android.intent.extra.STREAM"
You don't have to use the built-in standard names, but it's probably good practice and more reusable. Take a look at the developer documentation for a list of all the built-in standard extra data fields.
Path.GetDirectoryName(Application.ExecutablePath)
eg. value:
C:\Projects\ConsoleApplication1\bin\Debug
I had the same problem. I changed the order of the scripts in the head part, and it worked for me. Every script the plugin needs - needs to stay close.
For example:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script type="text/javascript" src="http://cloud.github.com/downloads/malsup/cycle/jquery.cycle.all.latest.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#slider').cycle({
fx: 'fade'
});
});
</script>
Okay. So this is a very old question and has great answers from that time. But a lot has changed since then.
Now, in 2020, if you are working with Kotlin and want to change the fragment then you can do the following.
In your app level build.gradle
file add the following,
dependencies {
def fragment_version = "1.2.5"
// Kotlin
implementation "androidx.fragment:fragment-ktx:$fragment_version"
// Testing Fragments in Isolation
debugImplementation "androidx.fragment:fragment-testing:$fragment_version"
}
In your activity
supportFragmentManager.commit {
replace(R.id.frame_layout, YourFragment.newInstance(), "Your_TAG")
addToBackStack(null)
}

A refinement to JustinStolle's edit (Eran Yogev's use of BlockCopy).
The proposed solution is indeed faster than using Encoding. Problem is that it doesn't work for encoding byte arrays of uneven length. As given, it raises an out-of-bound exception. Increasing the length by 1 leaves a trailing byte when decoding from string.
For me, the need came when I wanted to encode from DataTable
to JSON
.
I was looking for a way to encode binary fields into strings and decode from string back to byte[]
.
I therefore created two classes - one that wraps the above solution (when encoding from strings it's fine, because the lengths are always even), and another that handles byte[]
encoding.
I solved the uneven length problem by adding a single character that tells me if the original length of the binary array was odd ('1') or even ('0')
As follows:
public static class StringEncoder
{
static byte[] EncodeToBytes(string str)
{
byte[] bytes = new byte[str.Length * sizeof(char)];
System.Buffer.BlockCopy(str.ToCharArray(), 0, bytes, 0, bytes.Length);
return bytes;
}
static string DecodeToString(byte[] bytes)
{
char[] chars = new char[bytes.Length / sizeof(char)];
System.Buffer.BlockCopy(bytes, 0, chars, 0, bytes.Length);
return new string(chars);
}
}
public static class BytesEncoder
{
public static string EncodeToString(byte[] bytes)
{
bool even = (bytes.Length % 2 == 0);
char[] chars = new char[1 + bytes.Length / sizeof(char) + (even ? 0 : 1)];
chars[0] = (even ? '0' : '1');
System.Buffer.BlockCopy(bytes, 0, chars, 2, bytes.Length);
return new string(chars);
}
public static byte[] DecodeToBytes(string str)
{
bool even = str[0] == '0';
byte[] bytes = new byte[(str.Length - 1) * sizeof(char) + (even ? 0 : -1)];
char[] chars = str.ToCharArray();
System.Buffer.BlockCopy(chars, 2, bytes, 0, bytes.Length);
return bytes;
}
}
No one has mentioned this yet, and this may not be a common problem, but I had a similar problem with Xcode 5: Make sure you have a default keychain selected in the Mac's Keychain Access. I trying out a fresh install of Mountain Lion and deleted one keychain, which happened to be the default. After setting another keychain as the default (right-click on the keychain and select Make Keychain "Keychain_name" default"), Xcode was able to set up the valid signing identities.

You need to update to the latest gradle
version to solve this issue.
Please make sure you are on the latest Android Studio
and then update your project level build.gradle
by updating this dependency
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:4.0.0'
}
}
It might show a popup asking your permission to update gradle
, please update and it will download the latest distribution automatically and the issue will be resolved.
Or else you can
Get Latest Gradle 5.6.4 from here and Add it manually
If you don't want to download it manually:
Open YourProject > gradle > wrapper > gradle-wrapper.properties
and replace
distributionUrl=https\://services.gradle.org/distributions/gradle-version-number-all.zip
With
distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip
Rebuild the project or just run gradle sync again.
That would be the ALL_DIRECTORIES view:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28320/statviews_1075.htm#i1576965
The universal adb driver installer worked for me. I went from an HTC to a Samsung to a LG Nexus. The drivers are all over the place for me.
Download and install LINQPad, it works for SQL Server, MySQL, SQLite and also SDF (SQL CE 4.0).
Steps for open SDF Files:
Click Add Connection
Select Build data context automatically and Default (LINQ to SQL), then Next.
Under Provider choose SQL CE 4.0.
Under Database with Attach database file selected, choose Browse to select your .sdf file.
Click OK.
Add this line to Preferences -> Key Bindings - User
opening file:
{ "keys": ["alt+l"], "command": "open_in_browser"}
Add this line to Tools -> Build System -> New Build System...
opening file, and save with name "OpenWithChrome.sublime-build"
"shell_cmd": "C:\\PROGRA~1\\Google\\Chrome\\APPLIC~1\\chrome.exe $file"
Then you can browse/open the file by selecting Tools -> Build System -> OpenWithChrome
and pressing F7
or Ctrl+B
key.
This should also work and is a closer answer to what is asked in the question:
for i in range(len(x)):
if valeur.item(i) <= 0.6:
print ("this works")
else:
print ("valeur is too high")
for me the following commands worked:
$ brew install mysql
$ brew services start mysql
I believe that variable names aren't stored in pyc/pyd/pyo files, so you can not retrieve the exact code lines if you don't have source files.
I had to reinstall protractor for it to pull the updated webdriver-manager
module. Also, per @Mark’s comment, the package-lock.json
may be locking the dependency.
npm uninstall protractor
npm install --save-dev protractor
Then, make sure to check the maxChromedriver
value in node_modules/protractor/node_modules/webdriver-manager/config.json
after re-install to verify it matches the desired Chrome driver version.
$this is a special variable and it refers to the same object ie. itself.
it actually refer instance of current class
here is an example which will clear the above statement
<?php
class Books {
/* Member variables */
var $price;
var $title;
/* Member functions */
function setPrice($par){
$this->price = $par;
}
function getPrice(){
echo $this->price ."<br/>";
}
function setTitle($par){
$this->title = $par;
}
function getTitle(){
echo $this->title ." <br/>";
}
}
?>
Please use this tested working code. This function will return a list of all the CSV files with absolute CSV file paths in your specified path.
import os
from glob import glob
def get_csv_files(dir_path, ext):
os.chdir(dir_path)
return list(map(lambda x: os.path.join(dir_path, x), glob(f'*.{ext}')))
print(get_csv_files("E:\\input\\dir\\path", "csv"))
In later Elasticsearch versions (7.x), types were removed. Updating a mapping can becomes:
curl -XPUT "http://localhost:9200/test/_mapping" -H 'Content-Type: application/json' -d'{
"properties": {
"new_geo_field": {
"type": "geo_point"
}
}
}'
As others have pointed out, if the field exists, you typically have to reindex. There are exceptions, such as adding a new sub-field or changing analysis settings.
You can't "create a mapping", as the mapping is created with the index. Typically, you'd define the mapping when creating the index (or via index templates):
curl -XPUT "http://localhost:9200/test" -H 'Content-Type: application/json' -d'{
"mappings": {
"properties": {
"foo_field": {
"type": "text"
}
}
}
}'
That's because, in production at least, you'd want to avoid letting Elasticsearch "guess" new fields. Which is what generated this question: geo data was read as an array of long
values.
Yes, the DataTable.Select
method supports boolean operators in the same way that you would use them in a "real" SQL statement:
DataRow[] results = table.Select("A = 'foo' AND B = 'bar' AND C = 'baz'");
See DataColumn.Expression in MSDN for the syntax supported by DataTable's Select
method.

I've found the Sync with Active Document
button in the solution explorer to be the the most effective (this may be a vs2013 feature!)
updated() should be what you're looking for:
Called after a data change causes the virtual DOM to be re-rendered and patched.
The component’s DOM will have been updated when this hook is called, so you can perform DOM-dependent operations here.
I don't know how it crazy it looks but it does the job really well
ascii2hex(){ a="$@";s=0000000;printf "$a" | hexdump | grep "^$s"| sed s/' '//g| sed s/^$s//;}
Created this when I was trying to see my name in HEX ;) use how can you use it :)
Might sound stupid, But Params doesn't allow multidimensional array. Whereas you can pass a multidimensional array to a function.
If you're not restricted to JQuery, you can use the prototype.js framework. It has a class called Hash: You can even use JQuery & prototype.js together. Just type jQuery.noConflict();
var h = new Hash();
h.set("key", "value");
h.get("key");
h.keys(); // returns an array of keys
h.values(); // returns an array of values

So I made 2020 answer here
My directory looks like this
+-- docker-compose.yml
+-- mongo-entrypoint
+-- entrypoint.js
My docker-compose.yml
looks like this
version: '3.4'
services:
mongo-container:
# If you need to connect to your db from outside this container
network_mode: host
image: mongo:4.2
environment:
- MONGO_INITDB_ROOT_USERNAME=admin

volumes:
- "$PWD/mongo-entrypoint/:/docker-entrypoint-initdb.d/"
command: mongod
Please change admin
and pass
with your need.
Inside mongo-entrypoint
, I have entrypoint.js
file with this content:
var db = connect("mongodb://admin:pass@localhost:27017/admin");
db = db.getSiblingDB('new_db'); // we can not use "use" statement here to switch db
db.createUser(
{
user: "user",
pwd: "pass",
roles: [ { role: "readWrite", db: "new_db"} ],
passwordDigestor: "server",
}
)
Here again you need to change admin:pass
to your root mongo credentials in your docker-compose.yml
that you stated before. In additional you need to change new_db
, user
, pass
to your new database name and credentials that you need.
Now you can:
docker-compose up -d
And connect to this db from localhost, please note that I already have mongo cli, you can install it or you can exec to the container above to use mongo
command:
mongo new_db -u user -p pass
Or you can connect from other computer
mongo host:27017/new_db -u user -p pass

Try with this script, maybe will be useful:
SELECT CAST('TRUE' as bit) -- RETURN 1
SELECT CAST('FALSE' as bit) --RETURN 0
Anyway I always would use a value of 1 or 0 (not TRUE or FALSE). Following your example, the update script would be:
Update Table Set BitField=CAST('TRUE' as bit) Where ID=1

If I may quote my answer to the question StompChicken mentioned:
The core issue here is that stemming algorithms operate on a phonetic basis with no actual understanding of the language they're working with.
As they have no understanding of the language and do not run from a dictionary of terms, they have no way of recognizing and responding appropriately to irregular cases, such as "run"/"ran".
If you need to handle irregular cases, you'll need to either choose a different approach or augment your stemming with your own custom dictionary of corrections to run after the stemmer has done its thing.
We can use relative path instead of absolute path:
$assetPath: '~src/assets/images/';
$logo-img: '#{$assetPath}logo.png';
@mixin logo {
background-image: url(#{$logo-img});
}
.logo {
max-width: 65px;
@include logo;
}
Something along the lines of
StringWriter errors = new StringWriter();
ex.printStackTrace(new PrintWriter(errors));
return errors.toString();
Ought to be what you need.
Relevant documentation:
As Mingyu pointed out, there is a problem in formatting. Other than that, I would strongly recommend not using the Derived class's name while calling super()
since it makes your code inflexible (code maintenance and inheritance issues). In Python 3, Use super().__init__
instead. Here is the code after incorporating these changes :
class Car(object):
condition = "new"
def __init__(self, model, color, mpg):
self.model = model
self.color = color
self.mpg = mpg
class ElectricCar(Car):
def __init__(self, battery_type, model, color, mpg):
self.battery_type=battery_type
super().__init__(model, color, mpg)
Thanks to Erwin Mayer for pointing out the issue in using __class__
with super()
I have written a small web application in javascript for showing count of the number of downloads of all the assets in the available releases of any project on Github. You can try out the application over here: http://somsubhra.github.io/github-release-stats/
If this is a personal script, rather than one you're planning on distributing, it might be simpler to write a shell function for this:
function warextract { jar xf $1 $2 && mv $2 $3 }
which you could then call from python like so:
warextract /home/foo/bar/Portal.ear Binaries.war /home/foo/bar/baz/
If you really feel like it, you could use sed to parse out the filename from the path, so that you'd be able to call it with
warextract /home/foo/bar/Portal.ear /home/foo/bar/baz/Binaries.war
I'll leave that as an excercise to the reader, though.
Of course, since this will extract the .war out into the current directory first, and then move it, it has the possibility of overwriting something with the same name where you are.
Changing directory, extracting it, and cd-ing back is a bit cleaner, but I find myself using little one-line shell functions like this all the time when I want to reduce code clutter.
I fixed this by passing the redirect url to the FacebookRedirectLoginHelper::getAccessToken()
in my callback function:
Changing from
try {
$accessToken = $helper->getAccessToken();
}
...
to
try {
$accessToken = $helper->getAccessToken($fbRedirectUrl);
}
...
I am developing on a vagrant box, and it seems FacebookRedirectLoginHelper::getCurrentUrl()
had issues generating a valid url.
Here's an example that actually filters for BIN files. Also Windows now want you to save files to user locations, not system locations, so here's an example (you can use intellisense to browse the other options):
var saveFileDialog = new Microsoft.Win32.SaveFileDialog()
{
DefaultExt = "*.xml",
Filter = "BIN Files (*.bin)|*.bin",
InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments),
};
var result = saveFileDialog.ShowDialog();
if (result != null && result == true)
{
// Save the file here
}
ALTER TABLE `0_ms_labdip_details` DROP INDEX column_tcx

Note that sometimes you will want to use the class type name inside its own definition, for example when using Python Typing module, e.g.
class Tree:
def __init__(self, left: Tree, right: Tree):
self.left = left
self.right = right
This will also result in
NameError: name 'Tree' is not defined
That's because the class has not been defined yet at this point. The workaround is using so called Forward Reference, i.e. wrapping a class name in a string, i.e.
class Tree:
def __init__(self, left: 'Tree', right: 'Tree'):
self.left = left
self.right = right
The command for commiting all changed files:
git commit -a -m 'My commit comments'
-a
= all edited files
-m
= following string is a comment.
This will commit to your local drives / folders repo. If you want to push your changes to a git server / remotely hosted server, after the above command type:
git push
GitHub's cheat sheet is quite handy.
I also came across this issue while using the Quarkus microservice framework:
public class SomeResource {
@GET
@RolesAllowed({"basic"})
public Response doSomething(@Context SecurityContext context) {
// ...
}
}
// this will generate an QuerySyntax exception, as the authorization module
// will ignore the Entity annotation and use the class name instead.
@Entity(name = "users")
@UserDefinition
public class User {
// ...
}
// do this instead
@Entity
@Table(name = "users")
@UserDefinition
public class User {
// ...

If you wrap the container in a dummy P
tag you will get the container HTML also.
All you need to do is
var x = $('#container').wrap('<p/>').parent().html();
Check working example at http://jsfiddle.net/rzfPP/68/
To unwrap()
the <p>
tag when done, you can add
$('#container').unwrap();
The import wizard does offer that option. You can either use the option to write your own query for the data to import, or you can use the copy data option and use the "Edit Mappings" button to ignore columns you do not want to import.
you should do as:
getline(name, sizeofname, '\n');
strtok(name, " ");
This will give you the "joht" in name then to get next token,
temp = strtok(NULL, " ");
temp will get "smith" in it. then you should use string concatination to append the temp at end of name. as:
strcat(name, temp);
(you may also append space first, to obtain a space in between).
There are a lot of good answers on this thread. My solution for this issue was to write a script.
Name this 'git-scriptname' (and make it executable and put it in your PATH, like any script), and you can invoke it like a normal git command by running
$ git scriptname
The actual functionality is just the last line. Here's the source:
#!/usr/bin/env zsh
#
# Show a side-by-side diff of a particular file how it currently exists between:
# * the file system
# * in HEAD (latest committed changes)
function usage() {
cat <<-HERE
USAGE
$(basename $1) <file>
Show a side-by-side diff of a particular file between the current versions:
* on the file system (latest edited changes)
* in HEAD (latest committed changes)
HERE
}
if [[ $# = 0 ]]; then
usage $0
exit
fi
file=$1
diff -y =(git show HEAD:$file) $file | pygmentize -g | less -R
For those who need to figure out simple way
Try getActivity().onBackPressed();
You likely want to use onupdate=datetime.now
so that UPDATEs also change the last_updated
field.
SQLAlchemy has two defaults for python executed functions.
default
sets the value on INSERT, only onceonupdate
sets the value to the callable result on UPDATE as well.Yes, for scalar values, a combination of implode and array_slice will do:
$bar = implode(array_slice($array, 0, 1));
$bin = implode(array_slice($array, 1, 1));
$ipsum = implode(array_slice($array, 2, 1));
Or mix it up with array_values
and list
(thanks @nikic) so that it works with all types of values:
list($bar) = array_values(array_slice($array, 0, 1));
On the selected answer I see that when initially the page is loaded the selection of first option is prior fixed and therefore gives the option of all the categories in selection 2.
You can avoid that by adding the first option as the following in both the select tag:- <option value="none" selected disabled hidden>Select an Option</option>
<select name="select1" id="select1">
<option value="none" selected disabled hidden>Select an Option</option>
<option value="1">Fruit</option>
<option value="2">Animal</option>
<option value="3">Bird</option>
<option value="4">Car</option>
</select>
<select name="select2" id="select2">
<option value="none" selected disabled hidden>Select an Option</option>
<option value="1">Banana</option>
<option value="1">Apple</option>
<option value="1">Orange</option>
<option value="2">Wolf</option>
<option value="2">Fox</option>
<option value="2">Bear</option>
<option value="3">Eagle</option>
<option value="3">Hawk</option>
<option value="4">BWM<option>
</select>
The default value is indeed false.
However you can't use a local variable is it's not been assigned first.
You can use the default keyword to verify:
bool foo = default(bool);
if (!foo) { Console.WriteLine("Default is false"); }
exec
is not an expression: a statement in Python 2.x, and a function in Python 3.x. It compiles and immediately evaluates a statement or set of statement contained in a string. Example:
exec('print(5)') # prints 5.
# exec 'print 5' if you use Python 2.x, nor the exec neither the print is a function there
exec('print(5)\nprint(6)') # prints 5{newline}6.
exec('if True: print(6)') # prints 6.
exec('5') # does nothing and returns nothing.
eval
is a built-in function (not a statement), which evaluates an expression and returns the value that expression produces. Example:
x = eval('5') # x <- 5
x = eval('%d + 6' % x) # x <- 11
x = eval('abs(%d)' % -100) # x <- 100
x = eval('x = 5') # INVALID; assignment is not an expression.
x = eval('if 1: x = 4') # INVALID; if is a statement, not an expression.
compile
is a lower level version of exec
and eval
. It does not execute or evaluate your statements or expressions, but returns a code object that can do it. The modes are as follows:
compile(string, '', 'eval')
returns the code object that would have been executed had you done eval(string)
. Note that you cannot use statements in this mode; only a (single) expression is valid.
compile(string, '', 'exec')
returns the code object that would have been executed had you done exec(string)
. You can use any number of statements here.
compile(string, '', 'single')
is like the exec
mode but expects exactly one expression/statement, eg compile('a=1 if 1 else 3', 'myf', mode='single')
You want to use the live()
function. See the docs.
For example:
$("#anchor1").live("click", function() {
$("#anchor1").append('<a class="myclass" href="#">test4</a>');
});
Correct answer is simply:
SELECT a.group_id
FROM a
LEFT JOIN b ON a.group_id=b.group_id and b.user_id = 4
where b.user_id is null
and a.keyword like '%keyword%'
Here we are checking user_id = 4
(your user id from the session). Since we have it in the join criteria, it will return null values for any row in table b that does not match the criteria - ie, any group that that user_id is NOT in.
From there, all we need to do is filter for the null values, and we have all the groups that your user is not in.
Separation of concerns is the biggy.
Being able to tease these components apart makes the code easier to re-use and independently test. If you don't actually know what MVC is, be careful about trying to understand people's opinions as there is still some contention about what the "Model" is (whether it is the business objects/DataSets/DataTables or if it represents the underlying service layer).
I've seen all sorts of implementations that call themselves MVC but aren't exactly and as the comments in Jeff's article show MVC is a contentious point that I don't think developers will ever fully agree upon.
A good round up of all of the different MVC types is available here.
It's indeed doable to query the manifest or blob info from docker registry server without pulling the image to local disk.
You can refer to the Registry v2 API to fetch the manifest of image.
GET /v2/<name>/manifests/<reference>
Note, you have to handle different manifest version. For v2 you can directly get the size of layer and digest of blob. For v1 manifest, you can HEAD the blob download url to get the actual layer size.
There is a simple script for handling above cases that will be continuously maintained.
You can create your custom helper function here
function plusToDate(currentDate, unit, howMuch) {
var config = {
second: 1000, // 1000 miliseconds
minute: 60000,
hour: 3600000,
day: 86400000,
week: 604800000,
month: 2592000000, // Assuming 30 days in a month
year: 31536000000 // Assuming 365 days in year
};
var now = new Date(currentDate);
return new Date(now + config[unit] * howMuch);
}
var today = new Date();
var theDayAfterTommorow = plusToDate(today, 'day', 2);
By the way, this is generic solution for adding seconds or minutes or days whatever you want.
The Return type of the length() method of the String class is int.
public int length()
Refer http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#length()
So the maximum value of int is 2147483647.
String is considered as char array internally,So indexing is done within the maximum range. This means we cannot index the 2147483648th member.So the maximum length of String in java is 2147483647.
Primitive data type int is 4 bytes(32 bits) in java.As 1 bit (MSB) is used as a sign bit,The range is constrained within -2^31 to 2^31-1 (-2147483648 to 2147483647). We cannot use negative values for indexing.So obviously the range we can use is from 0 to 2147483647.

I created a jar
library called JCDP (Java Colored Debug Printer).
For Linux it uses the ANSI escape codes that WhiteFang mentioned, but abstracts them using words instead of codes which is much more intuitive.
For Windows it actually includes the JAnsi library but creates an abstraction layer over it, maintaining the intuitive and simple interface created for Linux.
This library is licensed under the MIT License so feel free to use it.
Have a look at JCDP's github repository.
In your example parts of your passed-in URL are not URL encoded (for example the colon should be %3A, the forward slashes should be %2F). It looks like you have encoded the parameters to your parameter URL, but not the parameter URL itself. Try encoding it as well. You can use encodeURIComponent
.
Facebook uses what's called the Open Graph Protocol to decide what things to display when you share a link. The OGP looks at your page and tries to decide what content to show. We can lend a hand and actually tell Facebook what to take from our page.
The way we do that is with og:meta
tags.
The tags look something like this -
<meta property="og:title" content="Stuffed Cookies" />
<meta property="og:image" content="http://fbwerks.com:8000/zhen/cookie.jpg" />
<meta property="og:description" content="The Turducken of Cookies" />
<meta property="og:url" content="http://fbwerks.com:8000/zhen/cookie.html">
You'll need to place these or similar meta tags in the <head>
of your HTML file. Don't forget to substitute the values for your own!
For more information you can read all about how Facebook uses these meta tags in their documentation. Here is one of the tutorials from there - https://developers.facebook.com/docs/opengraph/tutorial/
Facebook gives us a great little tool to help us when dealing with these meta tags - you can use the Debugger to see how Facebook sees your URL, and it'll even tell you if there are problems with it.
One thing to note here is that every time you make a change to the meta tags, you'll need to feed the URL through the Debugger again so that Facebook will clear all the data that is cached on their servers about your URL.

Custom Buttons appear in their respective image colors. Setting the button type to "System" in the storyboard (or to UIButtonTypeSystem
in code), will render the button's image with the default tint color.
(tested on iOS9, Xcode 7.3)
For showing result of batch file in text file, you can use
this command
chdir > test.txt
This command will redirect result to test.txt.
When you open test.txt you will found current path of directory in test.txt

You can also use HeapWalker from the Netbeans Profiler or the Visual VM stand-alone tool. Visual VM is a good alternative to JHAT as it is stand alone, but is much easier to use than JHAT.
You need Java 6+ to fully use Visual VM.

We all know that Java does not provide anything like the unsigned keyword. Moreover, a byte
primitive according to the Java's spec represents a value between -128
and 127
. For instance, if a byte
is cast
to an int
Java will interpret the first bit
as the sign
and use sign extension.
127
to its binary string representation ??Nothing prevents you from viewing a byte
simply as 8-bits and interpret those bits as a value between 0
and 255
. Also, you need to keep in mind that there's nothing you can do to force your interpretation upon someone else's method. If a method accepts a byte
, then that method accepts a value between -128
and 127
unless explicitly stated otherwise.
So the best way to solve this is convert the byte
value to an int
value by calling the Byte.toUnsignedInt()
method or casting it as a int
primitive (int) signedByte & 0xFF
. Here you have an example:
public class BinaryOperations
{
public static void main(String[] args)
{
byte forbiddenZeroBit = (byte) 0x80;
buffer[0] = (byte) (forbiddenZeroBit & 0xFF);
buffer[1] = (byte) ((forbiddenZeroBit | (49 << 1)) & 0xFF);
buffer[2] = (byte) 96;
buffer[3] = (byte) 234;
System.out.println("8-bit header:");
printBynary(buffer);
}
public static void printBuffer(byte[] buffer)
{
for (byte num : buffer) {
printBynary(num);
}
}
public static void printBynary(byte num)
{
int aux = Byte.toUnsignedInt(num);
// int aux = (int) num & 0xFF;
String binary = String.format("%8s', Integer.toBinaryString(aux)).replace(' ', '0');
System.out.println(binary);
}
}
8-bit header:
10000000
11100010
01100000
11101010
I would like to argue one point - that you cannot augment the original assembly - using Mono.Cecil you can inject [InternalsVisibleTo(...)]
to the 3pty assembly. Note there might be legal implications - you're messing with 3pty assembly and technical implications - if the assembly has strong name you either need to strip it or re-sign it with different key.
Install-Package Mono.Cecil
And the code like:
static readonly string[] s_toInject = {
// alternatively "MyAssembly, PublicKey=0024000004800000... etc."
"MyAssembly"
};
static void Main(string[] args) {
const string THIRD_PARTY_ASSEMBLY_PATH = @"c:\folder\ThirdPartyAssembly.dll";
var parameters = new ReaderParameters();
var asm = ModuleDefinition.ReadModule(INPUT_PATH, parameters);
foreach (var toInject in s_toInject) {
var ca = new CustomAttribute(
asm.Import(typeof(InternalsVisibleToAttribute).GetConstructor(new[] {
typeof(string)})));
ca.ConstructorArguments.Add(new CustomAttributeArgument(asm.TypeSystem.String, toInject));
asm.Assembly.CustomAttributes.Add(ca);
}
asm.Write(@"c:\folder-modified\ThirdPartyAssembly.dll");
// note if the assembly is strongly-signed you need to resign it like
// asm.Write(@"c:\folder-modified\ThirdPartyAssembly.dll", new WriterParameters {
// StrongNameKeyPair = new StrongNameKeyPair(File.ReadAllBytes(@"c:\MyKey.snk"))
// });
}

A template class is like a macro, only a whole lot less evil.
Think of a template as a macro. The parameters to the template get substituted into a class (or function) definition, when you define a class (or function) using a template.
The difference is that the parameters have "types" and values passed are checked during compilation, like parameters to functions. The types valid are your regular C++ types, like int and char. When you instantiate a template class, you pass a value of the type you specified, and in a new copy of the template class definition this value gets substituted in wherever the parameter name was in the original definition. Just like a macro.
You can also use the "class
" or "typename
" types for parameters (they're really the same). With a parameter of one of these types, you may pass a type name instead of a value. Just like before, everywhere the parameter name was in the template class definition, as soon as you create a new instance, becomes whatever type you pass. This is the most common use for a template class; Everybody that knows anything about C++ templates knows how to do this.
Consider this template class example code:
#include <cstdio>
template <int I>
class foo
{
void print()
{
printf("%i", I);
}
};
int main()
{
foo<26> f;
f.print();
return 0;
}
It's functionally the same as this macro-using code:
#include <cstdio>
#define MAKE_A_FOO(I) class foo_##I \
{ \
void print() \
{ \
printf("%i", I); \
} \
};
MAKE_A_FOO(26)
int main()
{
foo_26 f;
f.print();
return 0;
}
Of course, the template version is a billion times safer and more flexible.
My observations based on a few tests has been that whichever name differs from the property name is one which takes effect:
For eg. consider a slight modification of your case:
@JsonProperty("fileName")
private String fileName;
@JsonProperty("fileName")
public String getFileName()
{
return fileName;
}
@JsonProperty("fileName1")
public void setFileName(String fileName)
{
this.fileName = fileName;
}
Both fileName
field, and method getFileName
, have the correct property name of fileName
and setFileName
has a different one fileName1
, in this case Jackson will look for a fileName1
attribute in json at the point of deserialization and will create a attribute called fileName1
at the point of serialization.
Now, coming to your case, where all the three @JsonProperty differ from the default propertyname of fileName
, it would just pick one of them as the attribute(FILENAME
), and had any on of the three differed, it would have thrown an exception:
java.lang.IllegalStateException: Conflicting property name definitions
Pay attention that in http.Request header "Host" can not be set via Set
method
req.Header.Set("Host", "domain.tld")
but can be set directly:
req.Host = "domain.tld"
:
req, err := http.NewRequest("GET", "http://10.0.0.1/", nil)
if err != nil {
...
}
req.Host = "domain.tld"
client := &http.Client{}
resp, err := client.Do(req)
I think the best way to do this would be:
git diff remotes/origin/HEAD
Assuming that you have the this refspec registered. You should if you have cloned the repository, otherwise (i.e., if the repo was created de novo locally, and pushed to the remote), you need to add the refspec explicitly.

To remove untracked files / directories do:
git clean -fdx
-f - force
-d - directories too
-x - remove ignored files too ( don't use this if you don't want to remove ignored files)
Use with Caution!
These commands can permanently delete arbitrary files, that you havn't thought of at first. Please double check and read all the comments below this answer and the --help section, etc., so to know all details to fine-tune your commands and surely get the expected result.

This isn't directly answering the question, but to me, it looks like you might want the functionality of collections.Counter.
from collections import Counter
to_count = ["foo", "foo", "bar", "baz", "foo", "bar"]
count = Counter(to_count)
print(count)
print("acts just like the desired dictionary:")
print("bar occurs {} times".format(count["bar"]))
print("any item that does not occur in the list is set to 0:")
print("dog occurs {} times".format(count["dog"]))
print("can iterate over items from most frequent to least:")
for item, times in count.most_common():
print("{} occurs {} times".format(item, times))
This results in the output
Counter({'foo': 3, 'bar': 2, 'baz': 1})
acts just like the desired dictionary:
bar occurs 2 times
any item that does not occur in the list is set to 0:
dog occurs 0 times
can iterate over items from most frequent to least:
foo occurs 3 times
bar occurs 2 times
baz occurs 1 times
You can encapsulate your block of code with a try ... catch statement, and when you run your code, if the column doesn't exist it will throw an exception. You can then figure out what specific exception it throws and have it handle that specific exception in a different way if you so desire, such as returning "Column Not Found".
For an unmanaged DLL file, you need to first check if it is a 16-bit DLL file (hopefully not).
Then check the IMAGE\_FILE_HEADER.Machine

Someone else took the time to work this out already, so I will just repeat here:
To distinguish between a 32-bit and 64-bit PE file, you should check IMAGE_FILE_HEADER.Machine field. Based on the Microsoft PE and COFF specification below, I have listed out all the possible values for this field: http://download.microsoft.com/download/9/c/5/9c5b2167-8017-4bae-9fde-d599bac8184a/pecoff_v8.doc

You can add full text to an existing instance by changing the SQL Server program in Programs and Features. Follow the steps below. You might need the original disk or ISO for the installation to complete. (Per HotN's comment: If you have SQL Server Express, make sure it is SQL Server Express With Advanced Services.)
Directions:
On the Installation Type screen, select the appropriate SQL Server instance.
Advance through the rest of the wizard.

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to [Ljava.lang.Integer;
you try to cast an Array of Object to cast into Array of Integer. You cant do it. This type of downcast is not permitted.
You can make an array of Integer, and after that copy every value of the first array into second array.
There is a library called BoofCV which claims to better than ZBar and other libraries.
Here are the steps to use that (any OS).
Pre-requisites:
pip install pyboof
Class to decode:
import os
import numpy as np
import pyboof as pb
pb.init_memmap() #Optional
class QR_Extractor:
# Src: github.com/lessthanoptimal/PyBoof/blob/master/examples/qrcode_detect.py
def __init__(self):
self.detector = pb.FactoryFiducial(np.uint8).qrcode()
def extract(self, img_path):
if not os.path.isfile(img_path):
print('File not found:', img_path)
return None
image = pb.load_single_band(img_path, np.uint8)
self.detector.detect(image)
qr_codes = []
for qr in self.detector.detections:
qr_codes.append({
'text': qr.message,
'points': qr.bounds.convert_tuple()
})
return qr_codes
Usage:
qr_scanner = QR_Extractor()
output = qr_scanner.extract('Your-Image.jpg')
print(output)

Is because by the way python is designed the alternatives would hardly work. Python is designed to allow methods or functions to be defined in a context where both implicit this
(a-la Java/C++) or explicit @
(a-la ruby) wouldn't work. Let's have an example with the explicit approach with python conventions:
def fubar(x):
self.x = x
class C:
frob = fubar
Now the fubar
function wouldn't work since it would assume that self
is a global variable (and in frob
as well). The alternative would be to execute method's with a replaced global scope (where self
is the object).
The implicit approach would be
def fubar(x)
myX = x
class C:
frob = fubar
This would mean that myX
would be interpreted as a local variable in fubar
(and in frob
as well). The alternative here would be to execute methods with a replaced local scope which is retained between calls, but that would remove the posibility of method local variables.
However the current situation works out well:
def fubar(self, x)
self.x = x
class C:
frob = fubar
here when called as a method frob
will receive the object on which it's called via the self
parameter, and fubar
can still be called with an object as parameter and work the same (it is the same as C.frob
I think).

iText has more than one way of doing this. The PdfStamper
class is one option. But I find the easiest method is to create a new PDF document then import individual pages from the existing document into the new PDF.
// Create output PDF
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.getInstance(document, outputStream);
document.open();
PdfContentByte cb = writer.getDirectContent();
// Load existing PDF
PdfReader reader = new PdfReader(templateInputStream);
PdfImportedPage page = writer.getImportedPage(reader, 1);
// Copy first page of existing PDF into output PDF
document.newPage();
cb.addTemplate(page, 0, 0);
// Add your new data / text here
// for example...
document.add(new Paragraph("my timestamp"));
document.close();
This will read in a PDF from templateInputStream
and write it out to outputStream
. These might be file streams or memory streams or whatever suits your application.
A singleton should be used when managing access to a resource which is shared by the entire application, and it would be destructive to potentially have multiple instances of the same class. Making sure that access to shared resources thread safe is one very good example of where this kind of pattern can be vital.
When using Singletons, you should make sure that you're not accidentally concealing dependencies. Ideally, the singletons (like most static variables in an application) be set up during the execution of your initialization code for the application (static void Main() for C# executables, static void main() for java executables) and then passed in to all other classes that are instantiated which require it. This helps you maintain testability.
Easy steps to Integrate ckeditor with php pages
step 1 : download the ckeditor.zip file
step 2 : paste ckeditor.zip file on root directory of the site or you can paste it where the files are (i did this one )
step 3 : extract the ckeditor.zip file
step 4 : open the desired php page you want to integrate with here page1.php
step 5 : add some javascript first below, this is to call elements of ckeditor and styling and css without this you will only a blank textarea
<script type="text/javascript" src="ckeditor/ckeditor.js"></script>
And if you are using in other sites, then use relative links for that here is one below
<script type="text/javascript" src="somedirectory/ckeditor/ckeditor.js"></script>
step 6 : now!, you need to call the work code of ckeditor on your page page1.php below is how you call it
<?php
// Make sure you are using a correct path here.
include_once 'ckeditor/ckeditor.php';
$ckeditor = new CKEditor();
$ckeditor->basePath = '/ckeditor/';
$ckeditor->config['filebrowserBrowseUrl'] = '/ckfinder/ckfinder.html';
$ckeditor->config['filebrowserImageBrowseUrl'] = '/ckfinder/ckfinder.html?type=Images';
$ckeditor->config['filebrowserFlashBrowseUrl'] = '/ckfinder/ckfinder.html?type=Flash';
$ckeditor->config['filebrowserUploadUrl'] = '/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Files';
$ckeditor->config['filebrowserImageUploadUrl'] = '/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Images';
$ckeditor->config['filebrowserFlashUploadUrl'] = '/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Flash';
$ckeditor->editor('CKEditor1');
?>
step 7 : what ever you name you want, you can name to it ckeditor by changing the step 6 code last line
$ckeditor->editor('mycustomname');
step 8 : Open-up the page1.php, see it, use it, share it and Enjoy because we all love Open Source.
Thanks
SO thread 'Multiply two arrays element wise, where one of the arrays has arrays as elements' has an example of constructing an array from arrays. If the subarrays are the same size, numpy makes a 2d array. But if they differ in length, it makes an array with dtype=object
, and the subarrays retain their identity.
Following that, you could do something like this:
In [5]: result=np.array([np.zeros((1)),np.zeros((2))])
In [6]: result
Out[6]: array([array([ 0.]), array([ 0., 0.])], dtype=object)
In [7]: np.append([result[0]],[1,2])
Out[7]: array([ 0., 1., 2.])
In [8]: result[0]
Out[8]: array([ 0.])
In [9]: result[0]=np.append([result[0]],[1,2])
In [10]: result
Out[10]: array([array([ 0., 1., 2.]), array([ 0., 0.])], dtype=object)
However, I don't offhand see what advantages this has over a pure Python list or lists. It does not work like a 2d array. For example I have to use result[0][1]
, not result[0,1]
. If the subarrays are all the same length, I have to use np.array(result.tolist())
to produce a 2d array.
Simple Steps, follow them and i guess it will solve your problem

Then include the progress bar your body tag,
<div class="progress" id="PreLoaderBar">
<div class="indeterminate"></div>
</div>
then it will start as your page loads, and now what you have to do is just hide this when the page loads,or set the visibility to none, or hidden, using javascript,
document.onreadystatechange = function () {
if (document.readyState === "complete") {
console.log(document.readyState);
document.getElementById("PreLoaderBar").style.display = "none";
}
}
Let me Know if you face any problems and also, you can add any type of progress bar you can easily find them, for this example i have used a indeterminate progress bar.
You can't select a sheet in a non-active workbook.
You must first activate the workbook, then you can select the sheet.
workbooks("A").activate
workbooks("A").worksheets("B").select
When you use Activate it automatically activates the workbook.
Note you can select >1 sheet in a workbook:
activeworkbook.sheets(array("sheet1","sheet3")).select
but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.
I had this error coming up between 2 Linux boxes. Easily solved by installing RSYNC on the remote box as well as the local one.
This is a pretty clean way to do it:
myStr = ("firstPartOfMyString"+
"secondPartOfMyString"+
"thirdPartOfMyString")
I think, bwawok's answer is wrong at some point:
if you do
git reset --soft c14809fa
It will make your local files changed to be like they were then, but leave your history etc. the same.
According to manual: git-reset, "git reset --soft"...
does not touch the index file nor the working tree at all (but resets the head to <commit>, just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.
So it will "remove" newer commits from the branch. This means, after looking at your old code, you cannot go to the newest commit in this branch again, easily. So it does the opposide as described by bwawok: Local files are not changed (they look exactly as before "git reset --soft"), but the history is modified (branch is truncated after the specified commit).
The command for bwawok's answer might be:
git checkout <commit>
You can use this to peek at old revision: How did my code look yesterday?
(I know, I should put this in comments to this answer, but stackoverflow does not allow me to do so! My reputation is too low.)
If you don't want to recompute the previous command you can create a macro that scans the current terminal buffer, tries to guess the -supposed- output of the last command, copies it to the clipboard and finally types it to the terminal.
It can be used for simple commands that return a single line of output (tested on Ubuntu 18.04 with gnome-terminal
).
Install the following tools: xdootool
, xclip
, ruby
In gnome-terminal
go to Preferences -> Shortcuts -> Select all
and set it to Ctrl+shift+a
.
Create the following ruby script:
cat >${HOME}/parse.rb <<EOF
#!/usr/bin/ruby
stdin = STDIN.read
d = stdin.split(/\n/)
e = d.reverse
f = e.drop_while { |item| item == "" }
g = f.drop_while { |item| item.start_with? "${USER}@" }
h = g[0]
print h
EOF
In the keyboard settings add the following keyboard shortcut:
bash -c '/bin/sleep 0.3 ; xdotool key ctrl+shift+a ; xdotool key ctrl+shift+c ; ( (xclip -out | ${HOME}/parse.rb ) > /tmp/clipboard ) ; (cat /tmp/clipboard | xclip -sel clip ) ; xdotool key ctrl+shift+v '
The above shortcut:
What platform? If using .NET, use System.Uri.TryCreate
, not a regex.
For example:
static bool IsValidUrl(string urlString)
{
Uri uri;
return Uri.TryCreate(urlString, UriKind.Absolute, out uri)
&& (uri.Scheme == Uri.UriSchemeHttp
|| uri.Scheme == Uri.UriSchemeHttps
|| uri.Scheme == Uri.UriSchemeFtp
|| uri.Scheme == Uri.UriSchemeMailto
/*...*/);
}
// In test fixture...
[Test]
void IsValidUrl_Test()
{
Assert.True(IsValidUrl("http://www.example.com"));
Assert.False(IsValidUrl("javascript:alert('xss')"));
Assert.False(IsValidUrl(""));
Assert.False(IsValidUrl(null));
}

There is a get method in HashMap:
for (String keys : objectSet.keySet())
{
System.out.println(keys + ":"+ objectSet.get(keys));
}
To understand the name: A stack trace is a a list of Exceptions( or you can say a list of "Cause by"), from the most surface Exception(e.g. Service Layer Exception) to the deepest one (e.g. Database Exception). Just like the reason we call it 'stack' is because stack is First in Last out (FILO), the deepest exception was happened in the very beginning, then a chain of exception was generated a series of consequences, the surface Exception was the last one happened in time, but we see it in the first place.
Key 1:A tricky and important thing here need to be understand is : the deepest cause may not be the "root cause", because if you write some "bad code", it may cause some exception underneath which is deeper than its layer. For example, a bad sql query may cause SQLServerException connection reset in the bottem instead of syndax error, which may just in the middle of the stack.
-> Locate the root cause in the middle is your job.
Key 2:Another tricky but important thing is inside each "Cause by" block, the first line was the deepest layer and happen first place for this block. For instance,
Exception in thread "main" java.lang.NullPointerException
at com.example.myproject.Book.getTitle(Book.java:16)
at com.example.myproject.Author.getBookTitles(Author.java:25)
at com.example.myproject.Bootstrap.main(Bootstrap.java:14)
Book.java:16 was called by Auther.java:25 which was called by Bootstrap.java:14, Book.java:16 was the root cause. Here attach a diagram sort the trace stack in chronological order.
In my case (delete/insert data in my data structure) I needed to clear recycle pool and then notify data set changed!
mRecyclerView.getRecycledViewPool().clear();
mAdapter.notifyDataSetChanged();
I know this thread is old, but I just solved the problem for myself on OS X differently than described here.
Basically I reinstalled Python 2.7 through brew, and it comes with pip.
Install Xcode if not already:
xcode-select –install
Install Brew as described here:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Then install Python through Brew:
brew install python
And you're done. In my case I just needed to install pyserial.
pip install pyserial
In case you already have a "Configuration" with many migrations and want to keep this as is, you can always create a new "Configuration" class, give it another name, like
class MyNewContextConfiguration : DbMigrationsConfiguration<MyNewDbContext>
{
...
}
then just issue the command
Add-Migration -ConfigurationTypeName MyNewContextConfiguration InitialMigrationName
and EF will scaffold the migration without problems. Finally update your database, from now on, EF will complain if you don't tell him which configuration you want to update:
Update-Database -ConfigurationTypeName MyNewContextConfiguration
Done.
You don't need to deal with Enable-Migrations as it will complain "Configuration" already exists, and renaming your existing Configuration class will bring issues to the migration history.
You can target different databases, or the same one, all configurations will share the __MigrationHistory table nicely.

I've changed the original code to make it clearer and also to put it working fine in IE and also FF..
Original code HERE
How's this for an explantation to the layman. One way computers represent numbers is by counting discrete units. These are digital computers. For whole numbers, those without a fractional part, modern digital computers count powers of two: 1, 2, 4, 8. ,,, Place value, binary digits, blah , blah, blah. For fractions, digital computers count inverse powers of two: 1/2, 1/4, 1/8, ... The problem is that many numbers can't be represented by a sum of a finite number of those inverse powers. Using more place values (more bits) will increase the precision of the representation of those 'problem' numbers, but never get it exactly because it only has a limited number of bits. Some numbers can't be represented with an infinite number of bits.
Snooze...
OK, you want to measure the volume of water in a container, and you only have 3 measuring cups: full cup, half cup, and quarter cup. After counting the last full cup, let's say there is one third of a cup remaining. Yet you can't measure that because it doesn't exactly fill any combination of available cups. It doesn't fill the half cup, and the overflow from the quarter cup is too small to fill anything. So you have an error - the difference between 1/3 and 1/4. This error is compounded when you combine it with errors from other measurements.
A different approach that I found ugly compared to the classic dict+append, but that works:
df = df.T
df[0] = ['1/1/2013', 'Smith','test',123]
df = df.T
df
Out[6]:
Date Name Action ID
0 1/1/2013 Smith test 123
I think your expectations and reality don't match (but when do they ever ;))
Basically, where you think the file is written and where the file is actually written are not equal (hmmm, perhaps I should write an if
statement ;))
public class TestWriteFile {
public static void main(String[] args) {
BufferedWriter writer = null;
try {
//create a temporary file
String timeLog = new SimpleDateFormat("yyyyMMdd_HHmmss").format(Calendar.getInstance().getTime());
File logFile = new File(timeLog);
// This will output the full path where the file will be written to...
System.out.println(logFile.getCanonicalPath());
writer = new BufferedWriter(new FileWriter(logFile));
writer.write("Hello world!");
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
// Close the writer regardless of what happens...
writer.close();
} catch (Exception e) {
}
}
}
}
Also note that your example will overwrite any existing files. If you want to append the text to the file you should do the following instead:
writer = new BufferedWriter(new FileWriter(logFile, true));
Your family tree should use directed relations. This way you won't have a cycle.
C++14 (C++17 recommended) boost prf
Enum singleton
The simplest way to implement a Singleton that is thread-safe is using an Enum
public enum SingletonEnum {
INSTANCE;
public void doSomething(){
System.out.println("This is a singleton");
}
}
This code works since the introduction of Enum in Java 1.5
Double checked locking
If you want to code a “classic” singleton that works in a multithreaded environment (starting from Java 1.5) you should use this one.
public class Singleton {
private static volatile Singleton instance = null;
private Singleton() {
}
public static Singleton getInstance() {
if (instance == null) {
synchronized (Singleton.class){
if (instance == null) {
instance = new Singleton();
}
}
}
return instance ;
}
}
This is not thread-safe before 1.5 because the implementation of the volatile keyword was different.
Early loading Singleton (works even before Java 1.5)
This implementation instantiates the singleton when the class is loaded and provides thread safety.
public class Singleton {
private static final Singleton instance = new Singleton();
private Singleton() {
}
public static Singleton getInstance() {
return instance;
}
public void doSomething(){
System.out.println("This is a singleton");

You might need to allow different combinations of data in your intent filter to get it to work in different cases (http/
vs https/
, www.
vs no www.
, etc).
For example, I had to do the following for an app which would open when the user opened a link to Google Drive forms (www.docs.google.com/forms
)
Note that path prefix is optional.
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" />
<data android:scheme="https" />
<data android:host="www.docs.google.com" />
<data android:host="docs.google.com" />
<data android:pathPrefix="/forms" />
</intent-filter>
**Add Route function to direct the routine what you want**
public class SomeController : ApiController
{
[HttpGet()]
[Route("GetItems")]
public SomeValue GetItems(CustomParam parameter) { ... }
[HttpGet()]
[Route("GetChildItems")]
public SomeValue GetChildItems(CustomParam parameter, SomeObject parent) { ... }
}
If your Linux system supports it, clock_gettime(CLOCK_MONOTONIC) should be a high resolution timer that is unaffected by system date changes (e.g. NTP daemons).
The difference isn't in performance, but in capability. When using a reference directly you have more power over explicitly using a type of iterator (e.g. List.iterator() vs. List.listIterator(), although in most cases they return the same implementation). You also have the ability to reference the Iterator in your loop. This allows you to do things like remove items from your collection without getting a ConcurrentModificationException.
This is ok:
Set<Object> set = new HashSet<Object>();
// add some items to the set
Iterator<Object> setIterator = set.iterator();
while(setIterator.hasNext()){
Object o = setIterator.next();
if(o meets some condition){
setIterator.remove();
}
}
This is not, as it will throw a concurrent modification exception:
Set<Object> set = new HashSet<Object>();
// add some items to the set
for(Object o : set){
if(o meets some condition){
set.remove(o);
}
}
Yes, there is.
Variable can be local, field, or constant (although this is technically wrong). It's vague like attribute. Also, you should know that some people like to call final non-static (local or instance) variables
"Values". This probably comes from emerging JVM FP languages like Scala.
Field is generally a private variable on an instance class. It does not mean there is a getter and a setter.
Attribute is a vague term. It can easily be confused with XML or Java Naming API. Try to avoid using that term.
Property is the getter and setter combination.
Some examples below
public class Variables {
//Constant
public final static String MY_VARIABLE = "that was a lot for a constant";
//Value
final String dontChangeMeBro = "my god that is still long for a val";
//Field
protected String flipMe = "wee!!!";
//Property
private String ifYouThoughtTheConstantWasVerboseHaHa;
//Still the property
public String getIfYouThoughtTheConstantWasVerboseHaHa() {
return ifYouThoughtTheConstantWasVerboseHaHa;
}
//And now the setter
public void setIfYouThoughtTheConstantWasVerboseHaHa(String ifYouThoughtTheConstantWasVerboseHaHa) {
this.ifYouThoughtTheConstantWasVerboseHaHa = ifYouThoughtTheConstantWasVerboseHaHa;
}
}
There are many more combinations, but my fingers are getting tired :)
You can make responsive grid of squares with verticaly and horizontaly centered content only with CSS. I will explain how in a step by step process but first here are 2 demos of what you can achieve :
Now let's see how to make these fancy responsive squares!
The trick for keeping elements square (or whatever other aspect ratio) is to use percent padding-bottom
.
Side note: you can use top padding too or top/bottom margin but the background of the element won't display.
As top padding is calculated according to the width of the parent element (See MDN for reference), the height of the element will change according to its width. You can now Keep its aspect ratio according to its width.
At this point you can code :
HTML :
<div></div>
CSS
div {
width: 30%;
padding-bottom: 30%; /* = width for a square aspect ratio */
}
Here is a simple layout example of 3*3 squares grid using the code above.
With this technique, you can make any other aspect ratio, here is a table giving the values of bottom padding according to the aspect ratio and a 30% width.
Aspect ratio | padding-bottom | for 30% width
------------------------------------------------
1:1 | = width | 30%
1:2 | width x 2 | 60%
2:1 | width x 0.5 | 15%
4:3 | width x 0.75 | 22.5%
16:9 | width x 0.5625 | 16.875%
As you can't add content directly inside the squares (it would expand their height and squares wouldn't be squares anymore) you need to create child elements (for this example I am using divs) inside them with position: absolute;
and put the content inside them. This will take the content out of the flow and keep the size of the square.
Don't forget to add position:relative;
on the parent divs so the absolute children are positioned/sized relatively to their parent.
Let's add some content to our 3x3 grid of squares :
HTML :
<div class="square">
<div class="content">
.. CONTENT HERE ..
</div>
</div>
... and so on 9 times for 9 squares ...
CSS :
.square {
float:left;
position: relative;
width: 30%;
padding-bottom: 30%; /* = width for a 1:1 aspect ratio */
margin:1.66%;
overflow:hidden;
}
.content {
position:absolute;
height:80%; /* = 100% - 2*10% padding */
width:90%; /* = 100% - 2*5% padding */
padding: 10% 5%;
}
RESULT <-- with some formatting to make it pretty!
Horizontally :
This is pretty easy, you just need to add text-align:center
to .content
.
RESULT
Vertical alignment
This becomes serious! The trick is to use
display:table;
/* and */
display:table-cell;
vertical-align:middle;
but we can't use display:table;
on .square
or .content
divs because it conflicts with position:absolute;
so we need to create two children inside .content
divs. Our code will be updated as follow :
HTML :
<div class="square">
<div class="content">
<div class="table">
<div class="table-cell">
... CONTENT HERE ...
</div>
</div>
</div>
</div>
... and so on 9 times for 9 squares ...
CSS :
.square {
float:left;
position: relative;
width: 30%;
padding-bottom : 30%; /* = width for a 1:1 aspect ratio */
margin:1.66%;
overflow:hidden;
}
.content {
position:absolute;
height:80%; /* = 100% - 2*10% padding */
width:90%; /* = 100% - 2*5% padding */
padding: 10% 5%;
}
.table{
display:table;
height:100%;
width:100%;
}
.table-cell{
display:table-cell;
vertical-align:middle;
height:100%;
width:100%;
}
We have now finished and we can take a look at the result here :
EXEC sp_spaceused @oneresultset = 1
show in 1 row all of the result
if you execute just 'EXEC sp_spaceused' you will see two rows Work in SQL Server Management Studio v17.9
I'm using this:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(myUrl);
System.Diagnostics.Stopwatch timer = new Stopwatch();

statusCode = response.StatusCode.ToString();
response.Close();
timer.Stop();
Short answer: Yes. Use Python's urllib to pull the historical data pages for the stocks you want. Go with Yahoo! Finance; Google is both less reliable, has less data coverage, and is more restrictive in how you can use it once you have it. Also, I believe Google specifically prohibits you from scraping the data in their ToS.
Longer answer: This is the script I use to pull all the historical data on a particular company. It pulls the historical data page for a particular ticker symbol, then saves it to a csv file named by that symbol. You'll have to provide your own list of ticker symbols that you want to pull.
import urllib
base_url = "http://ichart.finance.yahoo.com/table.csv?s="
def make_url(ticker_symbol):
return base_url + ticker_symbol
output_path = "C:/path/to/output/directory"
def make_filename(ticker_symbol, directory="S&P"):
return output_path + "/" + directory + "/" + ticker_symbol + ".csv"
def pull_historical_data(ticker_symbol, directory="S&P"):
try:
urllib.urlretrieve(make_url(ticker_symbol), make_filename(ticker_symbol, directory))
except urllib.ContentTooShortError as e:
outfile = open(make_filename(ticker_symbol, directory), "w")
outfile.write(e.content)
outfile.close()

There are several ways to do that. But do not just update to the earlier revision as suggested here.
The easiest way to revert the changes from a single revision, or from a range of revisions, is to use the revision log dialog. This is also the method to use of you want to discard recent changes and make an earlier revision the new HEAD.
Show All
or Next 100
to show the revision(s) you are interested in.Context Menu
? Revert
changes from this revision.Context Menu
? Revert to this revision
. This will discard all changes after the selected revision. You have reverted the changes within your working copy. Check the results, then commit the changes.
All solutions are explained in the "How Do I..." part of the TortoiseSVN docs.
Since it has been a couple years and it doesn't seem possible to do this (using npm alone), a solution to this problem is to use the Nexus Repository Manager (from Sonatype). Nexus supports multiple repositories, lets you order them, and also proxies/caches to improve speed.
A free version and pro/paid version exist. The feature that supports this is described at: https://help.sonatype.com/repomanager3/node-packaged-modules-and-npm-registries
The relevant information is duplicated below so if/when the above URL/link stops working the information is still here.
A repository group is the recommended way to expose all your npm registries repositories from the repository manager to your users, without needing any further client side configuration. A repository group allows you to expose the aggregated content of multiple proxy and hosted repositories with one URL to npm and other tools.
It lets you create private npm registries
A private npm registry can be used to upload your own packages as well as third-party packages.
And
To reduce duplicate downloads and improve download speeds for your developers and CI servers, you should proxy the registry hosted at https://registry.npmjs.org. By default npm accesses this registry directly. You can also proxy any other registries you require.
So a quick bulleted list of things you do to get this working is:
Install Nexus
Create a local/private repo (or point to your private repo on another server)
Create a GROUP that lists your private repo, and the public repo.
Configure your $HOME/.npmrc file to point to the "GROUP" just created.
Publish your private npm packages to the local repo.
Users now can run a one time setup.
npm config set registry https://nexus/content/groups/GROUP
npm install
.
npm install my-private-package
npm install lodash any-other-public-package
And both your public and private packages can be installed via a simple npm install
command. Nexus finds the package searching each repo configured in the group and returns the results. So npm still thinks there is just one registry but behind the curtain there are multiple repos being used.
IMPORTANT NOTE: When you publish your components, you'll need to specify the npm publish --registry https://nexus/content/repositories/private-repo my-private-package
command so your package is published to the correct repo.
Remember that in git
you have:
HEAD
pointer, which tells you what commit you're working onPlease include detailed explanations about:
--hard
,--soft
and--merge
;
In increasing order of dangerous-ness:
--soft
moves HEAD
but doesn't touch the staging area or the working tree.--mixed
moves HEAD
and updates the staging area, but not the working tree.--merge
moves HEAD
, resets the staging area, and tries to move all the changes in your working tree into the new working tree.--hard
moves HEAD
and adjusts your staging area and working tree to the new HEAD
, throwing away everything.concrete use cases and workflows;
--soft
when you want to move to another commit and patch things up without "losing your place". It's pretty rare that you need this.--
# git reset --soft example
touch foo // Add a file, make some changes.
git add foo //
git commit -m "bad commit message" // Commit... D'oh, that was a mistake!
git reset --soft HEAD^ // Go back one commit and fix things.
git commit -m "good commit" // There, now it's right.
--
Use --mixed
(which is the default) when you want to see what things look like at another commit, but you don't want to lose any changes you already have.
Use --merge
when you want to move to a new spot but incorporate the changes you already have into that the working tree.
Use --hard
to wipe everything out and start a fresh slate at the new commit.

As some of my servers are on an old Ubuntu LTS versions, I can't easily upgrade git to the latest version (which supports the -C option as described in some answers).
This trick works well for me, especially because it does not have the side effect of some other answers that leave you in a different directory from where you started.
pushd /X/Y
git pull
popd
Or, doing it as a one-liner:
pushd /X/Y; git pull; popd
Both Linux and Windows have pushd and popd commands.
Per issue 12987, Blundell's answer crashes (at least on my 2.3 VM). Instead, I intercept a call to console.log with a special prefix:
// intercept calls to console.log
web.setWebChromeClient(new WebChromeClient() {
public boolean onConsoleMessage(ConsoleMessage cmsg)
{
// check secret prefix
if (cmsg.message().startsWith("MAGIC"))
{
String msg = cmsg.message().substring(5); // strip off prefix
/* process HTML */
return true;
}
return false;
}
});
// inject the JavaScript on page load
web.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String address)
{
// have the page spill its guts, with a secret prefix
view.loadUrl("javascript:console.log('MAGIC'+document.getElementsByTagName('html')[0].innerHTML);");
}
});
web.loadUrl("http://www.google.com");
For immutable objects, assignment creates a new copy of values, for example.
x=7
y=x
print(x,y)
x=10 # so for immutable objects this creates a new copy so that it doesnot
#effect the value of y
print(x,y)
For mutable objects, the assignment doesn't create another copy of values. For example,
x=[1,2,3,4]
print(x)
y=x #for immutable objects assignment doesn't create new copy
x[2]=5
print(x,y) # both x&y holds the same list
On windows:
py -3.4x32 -m venv venv34
or
py -2.6.2 -m venv venv26
This uses the py
launcher which will find the right python executable for you (assuming you have it installed).
... WHERE date_column >='2012-12-25' AND date_column <'2012-12-26'
may potentially work better(if you have an index on date_column) than DATE
.
This also includes the last date
$begin = new DateTime( "2015-07-03" );
$end = new DateTime( "2015-07-09" );
for($i = $begin; $i <= $end; $i->modify('+1 day')){
echo $i->format("Y-m-d");
}
If you dont need the last date just remove =
from the condition.
Use df.count()
to get the number of rows.
RanRag has already answered it for your specific question.
However, more generally, what you are doing with
if [[ "$string" =~ ^hello ]]
is a regex match. To do the same in Python, you would do:
import re
if re.match(r'^hello', somestring):
# do stuff
Obviously, in this case, somestring.startswith('hello')
is better.

Rachel's solution is working fine, although you need to use the third party script from raw.githubusercontent.com
By now there is a feature they show on the landing page when advertisng the "modular" script. You can see a legend there with this structure:
<div class="labeled-chart-container">
<div class="canvas-holder">
<canvas id="modular-doughnut" width="250" height="250" style="width: 250px; height: 250px;"></canvas>
</div>
<ul class="doughnut-legend">
<li><span style="background-color:#5B90BF"></span>Core</li>
<li><span style="background-color:#96b5b4"></span>Bar</li>
<li><span style="background-color:#a3be8c"></span>Doughnut</li>
<li><span style="background-color:#ab7967"></span>Radar</li>
<li><span style="background-color:#d08770"></span>Line</li>
<li><span style="background-color:#b48ead"></span>Polar Area</li>
</ul>
</div>
To achieve this they use the chart configuration option legendTemplate
legendTemplate : "<ul class=\"<%=name.toLowerCase()%>-legend\"><% for (var i=0; i<segments.length; i++){%><li><span style=\"background-color:<%=segments[i].fillColor%>\"></span><%if(segments[i].label){%><%=segments[i].label%><%}%></li><%}%></ul>"
You can find the doumentation here on chartjs.org This works for all the charts although it is not part of the global chart configuration.
Then they create the legend and add it to the DOM like this:
var legend = myPie.generateLegend();
$("#legend").html(legend);

When buffer size gets full. There are several options you can try:
1) Increase the size of the DBMS_OUTPUT buffer to 1,000,000
2) Try filtering the data written to the buffer - possibly there is a loop that writes to DBMS_OUTPUT and you do not need this data.
3) Call ENABLE at various checkpoints within your code. Each call will clear the buffer.
DBMS_OUTPUT.ENABLE(NULL) will default to 20000 for backwards compatibility Oracle documentation on dbms_output
You can also create your custom output display.something like below snippets
create or replace procedure cust_output(input_string in varchar2 )
is
out_string_in long default in_string;
string_lenth number;
loop_count number default 0;
begin
str_len := length(out_string_in);
while loop_count < str_len
loop
dbms_output.put_line( substr( out_string_in, loop_count +1, 255 ) );
loop_count := loop_count +255;
end loop;
end;

Possibly not the best solution in terms of what you are asking. I have still not determined an efficient method for removing anonymous function declared inline with the event listener invocation.
I personally use a variable to store the <target>
and declare the function outside of the event listener invocation eg:
const target = document.querySelector('<identifier>');
function myFunc(event) {
function code;
}
target.addEventListener('click', myFunc);
Then to remove the listener:
target.removeEventListener('click', myFunc);
Not the top recommendation you will receive but to remove anonymous functions the only solution I have found useful is to remove then replace the HTML element. I am sure there must be a better vanilla JS method but I haven't seen it yet.
This is the simplest answer I could create after reviewing others' answers:
def r5tor7():
while True:
cand = (5 * r5()) + r5()
if cand < 27:
return cand
cand
is in the range [6, 27] and the possible outcomes are evenly distributed if the possible outcomes from r5() are evenly distributed. You can test my answer with this code:
from collections import defaultdict
def r5_outcome(n):
if not n:
yield []
else:
for i in range(1, 6):
for j in r5_outcome(n-1):
yield [i] + j
def test_r7():
d = defaultdict(int)
for x in r5_outcome(2):
s = sum([x[i] * 5**i for i in range(len(x))])
if s < 27:
d[s] += 1
print len(d), d
r5_outcome(2)
generates all possible combinations of r5() results. I use the same filter to test as in my solution code. You can see that all of the outcomes are equally probably because they have the same value.
When signing into the server to execute the code use this instead:
ssh -X username@servername
the -X
will get rid of the no display name and no $DISPLAY environment variable

:)
On your project folder, open up the bin\Debug subfolder and you'll see the compiled result.
You can use a for loop:
for (i in 1:nrow(df)) {
df$col3[i] <- df$col1[i] + df$col2[i]
}

There are a few answers outlining differences between <depedencies>
and <dependencyManagement>
tags with maven.
However, few points elaborated below in a concise way:
<dependencyManagement>
allows to consolidate all dependencies (used at child pom level) used across different modules -- clarity, central dependency version management<dependencyManagement>
allows to easily upgrade/downgrade dependencies based on need, in other scenario this needs to be exercised at every child pom level -- consistency<dependencies>
tag is always imported, while dependencies provided at <dependencyManagement>
in parent pom will be imported only if child pom has respective entry in its <dependencies>

I had this problem. Code worked fine when running locally but not when on server. Using psPing (https://technet.microsoft.com/en-us/sysinternals/psping.aspx) I realised the applications port wasn't returning anything. Turned out to be a firewall issue. I hadn't enabled my applications port in the Windows Firewall.
Administrative Tools > Windows Firewall with Advanced Security added my applications port to the Inbound Rules and it started working.
Somehow the application port number had got changed, so took a while to figure out what was going on - so thought I'd share this possibility in case it saves someone else time...
Imo, you should try MySQL Connector/Node.js which is the official Node.js driver for MySQL. See ref-1 and ref-2 for detailed explanation. I have tried mysqljs/mysql which is available here, but I don't find detailed documentation on classes, methods, properties of this library.
So I switched to the standard MySQL Connector/Node.js
with X DevAPI
, since it is an asynchronous Promise-based client library and provides good documentation.
Take a look at the following code snippet :
const mysqlx = require('@mysql/xdevapi');
const rows = [];
mysqlx.getSession('mysqlx://localhost:33060')
.then(session => {
const table = session.getSchema('testSchema').getTable('testTable');
// The criteria is defined through the expression.
return table.update().where('name = "bar"').set('age', 50)
.execute()
.then(() => {
return table.select().orderBy('name ASC')
.execute(row => rows.push(row));
});
})
.then(() => {
console.log(rows);
});

where job_no like '0711%' or job_no like '0712%')
)
I know that this looks crazy, as you can just stick to using OR in your WHERE clause. why the subquery? How ever, the subquery approach will be useful when you have to match details from a different source.

You can also stringify the object and then again parse to make the normal object. For example like:-
const obj = JSON.parse(JSON.stringify(mongoObj))
Imagine a <span>
element inside a <div>
. If you give the <span>
element a height of 100px and a red border for example, it will look like this with
display: inline
display: inline-block
display: block
Code: http://jsfiddle.net/Mta2b/
Elements with display:inline-block
are like display:inline
elements, but they can have a width and a height. That means that you can use an inline-block element as a block while flowing it within text or other elements.
Difference of supported styles as summary:
margin-left
, margin-right
, padding-left
, padding-right
margin
, padding
, height
, width

Use MS Access. I have a file of 2,673,404 records. It will not open in notepad++ and excel will not load more than 1,048,576 records. It is tab delimited since I exported the data from a mysql database and I need it in csv format. So I imported it into Access. Change the file extension to .txt so MS Access will take you through the import wizard.
MS Access will link to your file so for the database to stay intact keep the csv file
%c
is designed for a single character a char, so it print only one element.Passing the char array as a pointer you are passing the address of the first element of the array(that is a single char) and then will be printed :
s
printf("%c\n",*name++);
will print
i
and so on ...
Pointer is not needed for the %s because it can work directly with String of characters.
Use .rsplit()
or .rpartition()
instead:
s.rsplit(',', 1)
s.rpartition(',')
str.rsplit()
lets you specify how many times to split, while str.rpartition()
only splits once but always returns a fixed number of elements (prefix, delimiter & postfix) and is faster for the single split case.
Demo:
>>> s = "a,b,c,d"
>>> s.rsplit(',', 1)
['a,b,c', 'd']
>>> s.rsplit(',', 2)
['a,b', 'c', 'd']
>>> s.rpartition(',')
('a,b,c', ',', 'd')
Both methods start splitting from the right-hand-side of the string; by giving str.rsplit()
a maximum as the second argument, you get to split just the right-hand-most occurrences.
This should work...
var displayDate = new Date().toLocaleDateString();
alert(displayDate);
But I suspect you are trying it on something else, for example:
var displayDate = Date.now.toLocaleDateString(); // No!
alert(displayDate);
So many questions here. I see at least two, maybe three:
*args
being used for?The first question is trivially answered in the Python Standard Library reference:
pop(key[, default])
If key is in the dictionary, remove it and return its value, else return default. If default is not given and key is not in the dictionary, a KeyError is raised.
The second question is covered in the Python Language Reference:
If the form “*identifier” is present, it is initialized to a tuple receiving any excess positional parameters, defaulting to the empty tuple. If the form “**identifier” is present, it is initialized to a new dictionary receiving any excess keyword arguments, defaulting to a new empty dictionary.
In other words, the pop
function takes at least two arguments. The first two get assigned the names self
and key
; and the rest are stuffed into a tuple called args
.
What's happening on the next line when *args
is passed along in the call to self.data.pop
is the inverse of this - the tuple *args
is expanded to of positional parameters which get passed along. This is explained in the Python Language Reference:
If the syntax *expression appears in the function call, expression must evaluate to a sequence. Elements from this sequence are treated as if they were additional positional arguments
In short, a.pop()
wants to be flexible and accept any number of positional parameters, so that it can pass this unknown number of positional parameters on to self.data.pop()
.
This gives you flexibility; data
happens to be a dict
right now, and so self.data.pop()
takes either one or two parameters; but if you changed data
to be a type which took 19 parameters for a call to self.data.pop()
you wouldn't have to change class a
at all. You'd still have to change any code that called a.pop()
to pass the required 19 parameters though.
With 500k documents, there is no reason to scale whatsoever. A typical laptop with an SSD and 8GB of ram can easily do 10s of millions of records, so if you are trying to pick because of scaling your choice doesn't really matter. I would suggest you pick what you like the most, and perhaps where you can find the most online support with.
The other answers here are great references on using proguard. However, I haven't seen an issue discussed that I ran into that was a mind bender. After you generate a signed release .apk, it's put in the /release
folder in your app but my app had an apk that wasn't in the /release
folder. Hence, I spent hours decompiling the wrong apk wondering why my proguard changes were having no affect. Hope this helps someone!
To provide an up-to-date answer: The best way to do this today is to use css grid layout like this:
.container {
display: grid;
grid-template-columns: 1fr 1fr 1fr;
grid-template-rows: auto;
grid-template-areas:
"top-left top-middle top-right"
"bottom bottom bottom"
}
.item-a {
grid-area: top-left;
}
.item-b {
grid-area: top-middle;
}
.item-c {
grid-area: top-right;
}
.item-d {
grid-area: bottom;
}
and the HTML
<div class="container">
<div class="item-a">1</div>
<div class="item-b">2</div>
<div class="item-c">3</div>
<div class="item-d">123</div>
</div>
I had the same issue, what worked for me:
Use the FULL path to the folder in your If Not Exist code. Then you won't even have to CD anymore:
If Not Exist "C:\Documents and Settings\John\Start Menu\Programs\SoftWareFolder\"
Here is a good short video explanation: https://www.youtube.com/watch?v=Acm-MD_6934
According to Ecma International Identifier Names are tokens that are interpreted according to the grammar given in the “Identifiers” section of chapter 5 of the Unicode standard, with some small modifications. An Identifier is an IdentifierName that is not a ReservedWord (see 7.6.1). The Unicode identifier grammar is based on both normative and informative character categories specified by the Unicode Standard. The characters in the specified categories in version 3.0 of the Unicode standard must be treated as in those categories by all conforming ECMAScript implementations.this standard specifies specific character additions:
The dollar sign ($) and the underscore (_) are permitted anywhere in an IdentifierName.
Further reading can be found on: http://www.ecma-international.org/ecma-262/5.1/#sec-7.6
Ecma International is an industry association founded in 1961 and dedicated to the standardization of Information and Communication Technology (ICT) and Consumer Electronics (CE).
Use a subquery:
SELECT * FROM
(
SELECT * FROM users ORDER BY rand() LIMIT 20
) T1
ORDER BY name
The inner query selects 20 users at random and the outer query orders the selected users by name.
