Contrary to all the other posts I suggest NOT using sudo
when installing gems.
Instead I recommend you install RVM and start a happy life with portable gem homes and different version of Ruby all living under one roof.
For the uninitiated, from the documentation:
RVM is a command line tool which allows us to easily install, manage and work with multiple ruby environments and sets of gems.
The reason why installing gems with sudo
is worse than just gem install
is because it installs the gems for ALL USERS as root
. This might be fine if you're the only person using the machine, but if you're not it can cause weirdness.
If you decide you want to blow away all your gems and start again it's much easier, and safer, to do so as a non-root user.
If you decide you want to use RVM
then using sudo
will cause all kinds of weirdness because each Ruby version you install through RVM
has its own GEM_HOME.
Also, it's nice if you can make your development environment as close to your production environment as possible, and in production you'll most likely install gems as a non-root user.
First make sure you have at least gem version 2.1.0
gem update --system
gem --version
# 2.6.4
To uninstall simply run:
gem uninstall --all
You may need to use the sudo
command:
sudo gem uninstall --all
Try: sudo chmod go-w /usr/local/bin
The /usr/local/bin directory is owned by the root
(i.e. administrator) account, so even if you can write to it, you can't change the permissions on it. The sudo
command means "run the following command as root", and works a lot like clicking that lock icon in the System Preferences dialogs.
on OSX mountain Lion: If you have brew
installed, then brew install mysql
and follow the instructions
on creating a test database with mysql on your machine.
You don't have to go all the way through, I didn't need to
After I did that I was able to bundle install and rake.
(January 2019) To install Ruby using the Rbenv script, follow these steps:
1. First, update the packages index and install the packages required for the ruby-build tool to build Ruby from source:
sudo apt-get remove ruby
sudo apt update
sudo apt install git curl libssl-dev libreadline-dev zlib1g-dev autoconf bison build-essential libyaml-dev libreadline-dev libncurses5-dev libffi-dev libgdbm-dev
2. Next, run the following curl command to install both rbenv and ruby-build:
curl -sL https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-installer | bash -
3. Add $HOME/.rbenv/bin to the system PATH.
If you are using Bash, run:
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
source ~/.bashrc
If you are using Zsh run:
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(rbenv init -)"' >> ~/.zshrc
source ~/.zshrc
4. Install the latest stable version of Ruby and set it as a default version with:
rbenv install 2.5.1
rbenv global 2.5.1
To list all available Ruby versions you can use:
rbenv install -l
5. Verify that Ruby was properly installed by printing out the version number:
ruby -v
# Output
ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]
SOURCE: How To Install Ruby on Ubuntu 18.04
EDIT: Install rubygems:
sudo apt-get install rubygems
A lot of people do a common mistake of thinking that 'rvm implode' does it . You need to delete all traces of any .rm files . Also , it will take some manual deletions from root . Make sure , it gets deleted and also all the ruby versions u installed using it .
If you want to work on a locally modified fork of a gem, the best way to do so is
gem 'pry', path: './pry'
in a Gemfile.
... where ./pry
would be the clone of your repository. Simply run bundle install
once, and any changes in the gem sources you make are immediately reflected. With gem install pry/pry.gem
, the sources are still moved into GEM_PATH
and you'll always have to run both bundle gem pry
and gem update
to test.
You can try export http_proxy=http://your_proxy:your_port
If you are on a *nix system, use this:
export http_proxy=http://${proxy.host}:${port}
export https_proxy=http://${proxy.host}:${port}
and then try:
gem install ${gem_name}
If you get an error similar like:
The following packages have unmet dependencies:
libmagickwand-dev : Depends: libmagickcore4-extra (= 8:6.6.9.7-5ubuntu3.2) but it is not going to be installed
Depends: libmagickcore-dev (= 8:6.6.9.7-5ubuntu3.2) but it is not going to be installed
You might want to start with this package: sudo apt-get install libgvc5

If you've read the previous sections, you will know what this means (and shame > on you if you have not).
We need to download AddTrustExternalCARoot-2048.pem. Open a Command Prompt and type in:
C:>gem which rubygems C:/Ruby21/lib/ruby/2.1.0/rubygems.rb Now, let's locate that directory. From within the same window, enter the path part up to the file extension, but using backslashes instead:
C:>start C:\Ruby21\lib\ruby\2.1.0\rubygems This will open a Explorer window inside the directory we indicated.
Step 3: Copy new trust certificate
Now, locate ssl_certs directory and copy the .pem file we obtained from previous step inside.
It will be listed with other files like GeoTrustGlobalCA.pem.

A problem I had on my Mac using rbenv was that when I first set it up, it loaded a bunch of ruby executables in /usr/local/bin - these executables loaded the system ruby, rather than the current version.
If you run
which bundle
And it shows /usr/local/bin/bundle you may have this issue.
Search through /usr/local/bin and delete any files that start with #!/user/bin ruby
Then run
rbenv rehash

The suggested answer only works for certain versions of ruby. Some commenters suggest using ruby-dev; that didn't work for me either.
sudo apt-get install ruby-all-dev
worked for me.
i had the same issue and tried all the answers without any luck.
steps i did to reproduce:
rvm instal 2.1.10
rvm gemset create my_gemset
rvm use 2.1.10@my_gemset
bundle install
however bundle install
installed Rails, but i still got
cannot load such file -- bundler/setup (LoadError)
finally running gem install rails -v 4.2
fixed it

Note that your pod specs will remain, and are located at ~/.cocoapods/ . This directory may also need to be removed if you want a completely fresh install.
They can be removed using pod spec remove SPEC_NAME
then pod setup
It may help to do pod spec remove master
then pod setup
bundler update --source gem-name
will update the revision hash in Gemfile.lock which you can compare with the last commit hash of that git branch (master by default).

Adding .gem
to vendor/cache
seems to work. No options required in Gemfile
.
In your Gemfile, add the following:
gem 'example', :git => 'git://github.com/example.git'
You can also add ref, branch and tag options,
For example if you want to download from a particular branch:
gem 'example', :git => "git://github.com/example.git", :branch => "my-branch"
Then run:
bundle install
I created my own Gem, but I did it in a directory that is not in my load path:
$ pwd
/Users/myuser/projects
$ gem build my_gem/my_gem.gemspec
Then I ran irb
and tried to load the Gem:
> require 'my_gem'
LoadError: cannot load such file -- my_gem
I used the global variable $: to inspect my load path and I realized I am using RVM. And rvm has specific directories in my load path $:
. None of those directories included my ~/projects directory where I created the custom gem.
So one solution is to modify the load path itself:
$: << "/Users/myuser/projects/my_gem/lib"
Note that the lib directory is in the path, which holds the my_gem.rb file which will be required in irb:
> require 'my_gem'
=> true
Now if you want to install the gem in RVM path, then you would need to run:
$ gem install my_gem
But it will need to be in a repository like rubygems.org.
$ gem push my_gem-0.0.0.gem
Pushing gem to RubyGems.org...

A better idea,
if you want to put the error message just beneath the text field, you can do like this
.row.spacer20top
.col-sm-6.form-group
= f.label :first_name, "*Your First Name:"
= f.text_field :first_name, :required => true, class: "form-control"
= f.error_message_for(:first_name)
What is error_message_for
?

Reinstalling RVM worked for me, but I had to reinstall all of my gems afterward:
rvm implode
\curl -sSL https://get.rvm.io | bash -s stable --ruby
rvm reload
Try updating your Ruby on Rails version to v3.0.5:
gem install rails --version 3.0.5
or v2.3.11:
gem install rails --version 2.3.11
If this isn't a new project you'll have to upgrade your application accordingly. If it was a new project, just delete the directory you created it in and create a new project again.
You need to install the entire ruby and not just the minimum package. The correct command to use is:
sudo apt install ruby-full
The following command will also not install a complete ruby:
sudo apt-get install ruby2.3-dev
You really should be using a Ruby version manager.
Using one properly would prevent and can resolve your permission problem when executing a gem update
command.
I recommend rbenv.
However, even when you use a Ruby version manager, you may still get that same error message.
If you do, and you are using rbenv, just verify that the ~/.rbenv/shims
directory is before the path for the system Ruby.
$ echo $PATH
will show you the order of your load path.
If you find that your shims directory comes after your system Ruby bin directory, then edit your ~/.bashrc
file and put this as your last export PATH command: export PATH=$HOME/.rbenv/shims:$PATH
$ ruby -v
shows you what version of Ruby you are using
This shows that I'm currently using the system version of Ruby (usually not good)
$ ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]
$ rbenv global 1.9.3-p448
switches me to a newer, pre-installed version (see references below).
This shows that I'm using a newer version of Ruby (that likely won't cause the Gem::FilePermissionError)
$ ruby -v
ruby 1.9.3p448 (2013-06-27 revision 41675) [x86_64-darwin12.4.0]
You typically should not need to preface a gem command with sudo. If you feel the need to do so, something is probably misconfigured.
For details about rbenv see the following:
Devise uses some generators to generate views and stuff it needs into your application. If you have run this generator, you can easily undo it with
rails destroy <name_of_generator>
The uninstallation of the gem works as described in the other posts.
To setup you Ruby development environment on Windows:
Install Ruby via RubyInstaller: http://rubyinstaller.org/downloads/
Check your ruby version: Start - Run - type in cmd
to open a windows console
ruby -v
ruby 2.0.0p353 (2013-11-22) [i386-mingw32]
For Ruby 2.4 or later, run the extra installation at the end to install the DevelopmentKit. If you forgot to do that, run ridk install
in your windows console to install it.
For earlier versions:
gem install {gem name}
. For example, to install rails, just run gem install rails
.Hope this helps.
I have solved this, eventually!
I re-installed Ruby and Rails under RVM. I'm using Ruby version 1.9.2-p136.
After re-installing under rvm, this error was still present.
In the end the magic command that solved it was:
sudo install_name_tool -change libmysqlclient.16.dylib /usr/local/mysql/lib/libmysqlclient.16.dylib ~/.rvm/gems/ruby-1.9.2-p136/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
Hope this helps someone else!
I have also met the same problem using rbenv + passenger + nginx. my solution is simply adding these 2 line of code to your nginx config:
passenger_default_user root;
passenger_default_group root;
the detailed answer is here: https://stackoverflow.com/a/15777738/445908
cocoapod on terminal follow this:
sudo gem update
sudo gem install cocoapods
pod setup
cd (project direct drag link)
pod init
open -aXcode podfile (if its already open add your pod file name ex:alamofire4.3)
pod install
pod update
I had the same issue today. I solve this problem by removing any PATH
in .bashrc
for older rvm
.
The following command installs ruby gem for ubuntu:
apt-get install libgemplugin-ruby
I did it after ruby was installed.
You can specify default options using the .gemrc
configuration file.
My gem version 2.0.3 and I was getting the same issue. This command resolved it:
gem install json --platform=ruby --verbose
In addition to specifying the path (as Jimmy mentioned) you can also force Bundler to use a local gem for your environment only by using the following configuration option:
$ bundle config local.GEM_NAME /path/to/local/git/repository
This is extremely helpful if you're developing two gems or a gem and a rails app side-by-side.
Note though, that this only works when you're already using git for your dependency, for example:
# In Gemfile
gem 'rack', :github => 'rack/rack', :branch => 'master'
# In your terminal
$ bundle config local.rack ~/Work/git/rack
As seen on the docs.
I have faced same issue after install macOS Catalina. I had try below command and its working.
sudo gem update
I needed to get the element as a string.
jQuery("#bob").get(0).outerHTML;
Which will give you something like:
<input type="text" id="bob" value="hello world" />
...as a string rather than a DOM element.

The easiest way is to create C# Process and launch external tool to print your PDF file

Code above launches RawFilePrinter.exe (similar to 2Printer.exe), but with better support. It is not free, but by making donation allow you to use it everywhere and redistribute with your application. Latest version to download: http://bigdotsoftware.pl/rawfileprinter
For me nothing from above worked. So I solved my problem with this workaround. Just check that you have added SYSTEM in directory folder. I hope it will help somoene.
import os
# create file
@staticmethod
def create_file(path):
if not os.path.exists(path):
os.system('echo # > {}'.format(path))
# append lines to the file
split_text = text_file.split('\n')
for st in split_text:
os.system('echo {} >> {}'.format(st,path))
Your problem is you have the b
in the open
flag.
The flag rt
(read, text) is the default, so, using the context manager, simply do this:
with open('sample.csv') as ifile:
read = csv.reader(ifile)
for row in read:
print (row)
The context manager means you don't need generic error handling (without which you may get stuck with the file open, especially in an interpreter), because it will automatically close the file on an error, or on exiting the context.
The above is the same as:
with open('sample.csv', 'r') as ifile:
...
or
with open('sample.csv', 'rt') as ifile:
...
This worked best for me
"0x%02X" % 5 # => 0x05
"0x%02X" % 17 # => 0x11
Change the (2) if you want a number with a bigger width (2 is for 2 hex printned chars) so 3 will give you the following

Better version using an Alias
Using an alias is a more efficient way to accomplish what you need and it also includes color. The following displays your results organized by group directories first, display in color, print sizes in human readable format (e.g., 1K 234M 2G) edit your ~/.bashrc
and add an alias for your account or globally by editing /etc/profile.d/custom.sh
Typing cls
displays your new LS command results.
alias cls="ls -lha --color=always -F --group-directories-first |awk '{k=0;s=0;for(i=0;i<=8;i++){;k+=((substr(\$1,i+2,1)~/[rwxst]/)*2^(8-i));};j=4;for(i=4;i<=10;i+=3){;s+=((substr(\$1,i,1)~/[stST]/)*j);j/=2;};if(k){;printf(\"%0o%0o \",s,k);};print;}'"
Folder Tree
While you are editing your bashrc or custom.sh include the following alias to see a graphical representation where typing lstree
will display your current folder tree structure
alias lstree="ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/ /' -e 's/-/|/'"
It would display:
|-scripts
|--mod_cache_disk
|--mod_cache_d
|---logs
|-run_win
|-scripts.tar.gz
Check out Javascript's Array API for details on the exact syntax for Array methods. Modifying your code to use the correct syntax would be:
var array = [];
calendars.forEach(function(item) {
array.push(item.id);
});
console.log(array);
You can also use the map()
method to generate an Array filled with the results of calling the specified function on each element. Something like:
var array = calendars.map(function(item) {
return item.id;
});
console.log(array);
And, since ECMAScript 2015 has been released, you may start seeing examples using let
or const
instead of var
and the =>
syntax for creating functions. The following is equivalent to the previous example (except it may not be supported in older node versions):
let array = calendars.map(item => item.id);
console.log(array);
=UNIQUE({filter(Core!L8:L27,isblank(Core!L8:L27)=false),query(ArrayFormula(countif(Core!L8:L27,Core!L8:L27)),"select Col1 where Col1 <> 0")})
Core!L8:L27 = list
Just Try this:

Go to SETTINGS->Location and Security-> Device Administrator and deselect the admin which you want to uninstall.
Now uninstall the application. If it still says you need to deactivate the application before uninstalling, you may need to Force Stop the application before uninstalling.
The best approach for you to communicate between the two controllers is to use events.
In this check out $on
, $broadcast
and $emit
.
In general use case the usage of angular.element(catapp).scope()
was designed for use outside the angular controllers, like within jquery events.
Ideally in your usage you would write an event in controller 1 as:
$scope.$on("myEvent", function (event, args) {
$scope.rest_id = args.username;
$scope.getMainCategories();
});
And in the second controller you'd just do
$scope.initRestId = function(){
$scope.$broadcast("myEvent", {username: $scope.user.username });
};
Edit: Realised it was communication between two modules
Can you try including the firstApp
module as a dependency to the secondApp
where you declare the angular.module
. That way you can communicate to the other app.
You may want to use Vim global marks.
This way you can quickly bounce between files, and even to the marked location in the file. Also, the key commands are short:
'C
takes me to the code I'm working with,
'T
takes me to the unit test I'm working with.
When you change places, resetting the marks is quick too:
mC
marks the new code spot,
mT
marks the new test spot.
for my example:
Windows XP ---> Synology:DS218+
Step2:
Enable Telnet service (?? Telnet ??)
or Enable SSH Service (?? SSH ??)
Step3: Launch the terminal on Windows (or via executing cmd

.blackText
{

<span class="redText">My Name is:</span> <span class="blackText">Tintincute</span>
It's also a good idea to avoid inline styling. Use a custom CSS class instead.

In Ubuntu you can apply this way,
path = default_storage.save('static/tmp/' + f1.name, ContentFile(f1.read()))
path12 = os.path.join(os.getcwd(), "static/tmp/" + f1.name)
data={} #can be anything u want to pass along with File
file1 = open(path12, 'rb')
header = {"Content-Disposition": "attachment; filename=" + f1.name, "Authorization": "JWT " + token}
res= requests.post(url,data,header)
Or echo 'put {path to file}' | sftp {user}@{host}:{dir}
, which would work in both unix and powershell.
Just had this happen to me.
Apparently Java's automatic updater installed and configured a new version of the JRE for me, while leaving the old JDK intact. So even though I did have a JDK, it didn't match the currently "active" JRE, which was causing the error.
Download a matching version of the JDK to the JRE you currently have installed, (In OP's case 151) That should do the trick.
To answer the original question: here is how you decode utf-8 in javascript:
http://ecmanaut.blogspot.ca/2006/07/encoding-decoding-utf8-in-javascript.html
Specifically,
function encode_utf8(s) {
return unescape(encodeURIComponent(s));
}
function decode_utf8(s) {
return decodeURIComponent(escape(s));
}
We have been using this in our production code for 6 years, and it has worked flawlessly.
Note, however, that escape() and unescape() are deprecated. See this.
It's not that key is a special word, but that dictionaries implement the iterator protocol. You could do this in your class, e.g. see this question for how to build class iterators.
In the case of dictionaries, it's implemented at the C level. The details are available in PEP 234. In particular, the section titled "Dictionary Iterators":
Dictionaries implement a tp_iter slot that returns an efficient iterator that iterates over the keys of the dictionary. [...] This means that we can write
for k in dict: ...
which is equivalent to, but much faster than
for k in dict.keys(): ...
as long as the restriction on modifications to the dictionary (either by the loop or by another thread) are not violated.
Add methods to dictionaries that return different kinds of iterators explicitly:
for key in dict.iterkeys(): ... for value in dict.itervalues(): ... for key, value in dict.iteritems(): ...
This means that
for x in dict
is shorthand forfor x in dict.iterkeys()
.
In Python 3, dict.iterkeys()
, dict.itervalues()
and dict.iteritems()
are no longer supported. Use dict.keys()
, dict.values()
and dict.items()
instead.

I think using the matrix.at<type>(x,y)
is not the best way to iterate trough a Mat object!
If I recall correctly matrix.at<type>(x,y)
will iterate from the beginning of the matrix each time you call it(I might be wrong though).
I would suggest using cv::MatIterator_
cv::Mat someMat(1, 4, CV_64F, &someData);;
cv::MatIterator_<double> _it = someMat.begin<double>();
for(;_it!=someMat.end<double>(); _it++){
std::cout << *_it << std::endl;
}

This is an update to Muhammed Neswine's answer
In Express 4.x, sendfile has been deprecated and sendFile function has to be used. The difference is sendfile takes relative path and sendFile takes absolute path. So, __dirname is used to avoid hardcoding the path.
var express = require('express');
var app = express();
var path = require("path");
app.get('/', function (req, res) {
res.sendFile(path.join(__dirname + '/folder_name/filename.html'));
});

Object.keys()

There is a lot of hate for this pattern in Java. However, an interface of static constants does sometimes have value. You need to basically fulfill the following conditions:
The concepts are part of the public interface of several classes.
Their values might change in future releases.
For example, suppose that you are writing an extension to a hypothetical query language. In this extension you are going to expand the language syntax with some new operations, which are supported by an index. E.g. You are going to have a R-Tree supporting geospatial queries.
So you write a public interface with the static constant:
public interface SyntaxExtensions {
// query type
String NEAR_TO_QUERY = "nearTo";
// params for query
String POINT = "coordinate";
String DISTANCE_KM = "distanceInKm";
}
Now later, a new developer thinks he needs to build a better index, so he comes and builds an R* implementation. By implementing this interface in his new tree he guarantees that the different indexes will have identical syntax in the query language. Moreover, if you later decided that "nearTo" was a confusing name, you could change it to "withinDistanceInKm", and know that the new syntax would be respected by all your index implementations.
PS: The inspiration for this example is drawn from the Neo4j spatial code.
I just discovered the Hmisc package:
Contains many functions useful for data analysis, high-level graphics, utility operations, functions for computing sample size and power, importing and annotating datasets, imputing missing values, advanced table making, variable clustering, character string manipulation, conversion of R objects to LaTeX and html code, and recoding variables.

An alternative would be to set a variable, and check whether it is defined:
SET ARG=%1
IF DEFINED ARG (echo "It is defined: %1") ELSE (echo "%%1 is not defined")
Unfortunately, using %1
directly with DEFINED
doesn't work.

If you do a lot with timing, I can recommend this little (20 line) context manager:
You code could look like this then:
#!/usr/bin/env python
# coding: utf-8
from timer import Timer
if __name__ == '__main__':
a, record = None, []
while not a == '':
with Timer() as t: # everything in the block will be timed
a = input('Type: ')
record.append(t.elapsed_s)
# drop the last item (makes a copy of the list):
record = record[:-1]
# or just delete it:
# del record[-1]
Just for reference, here's the content of the Timer context manager in full:
from timeit import default_timer
class Timer(object):
""" A timer as a context manager. """
def __init__(self):
self.timer = default_timer
# measures wall clock time, not CPU time!
# On Unix systems, it corresponds to time.time
# On Windows systems, it corresponds to time.clock
def __enter__(self):
self.start = self.timer() # measure start time
return self
def __exit__(self, exc_type, exc_value, exc_traceback):
self.end = self.timer() # measure end time
self.elapsed_s = self.end - self.start # elapsed time, in seconds
self.elapsed_ms = self.elapsed_s * 1000 # elapsed time, in milliseconds

"autoconf is an extensible package of M4 macros that produce shell scripts to automatically configure software source code packages. These scripts can adapt the packages to many kinds of UNIX-like systems without manual user intervention. Autoconf creates a configuration script for a package from a template file that lists the operating system features that the package can use, in the form of M4 macro calls."
"automake is a tool for automatically generating Makefile.in files compliant with the GNU Coding Standards. Automake requires the use of Autoconf."
Manuals:

Free online tutorials:
The main configure.ac used to build LibreOffice is over 12k lines of code, (but there are also 57 other configure.ac files in subfolders.)
From this my generated configure is over 41k lines of code.
And while the Makefile.in and Makefile are both only 493 lines of code. (But, there are also 768 more Makefile.in's in subfolders.)
It seems problem is not in JDK bug 6602600 ( it was solved at 2010-05-22), but in incorrect call of sleep(10) in circle. Addition note, that the main Thread must give directly CHANCE to other threads to realize thier tasks by invoke SLEEP(0) in EVERY branch of outer circle. It is better, I think, to use Thread.yield() instead of Thread.sleep(0)
The result corrected part of previous problem code is such like this:
.......................
........................
Thread.yield();
if (i % 1000== 0) {
System.out.println(i + "/" + counter.get()+ "/"+service.toString());
}
//
// while (i > counter.get()) {
// Thread.sleep(10);
// }
It works correctly with amount of outer counter up to 150 000 000 tested circles.
I Followed all the things mentioned in this thread but still facing same issue-

This is just additional info to answers in order to pass argument into the another file
Where you expect argument
PrintName.ps1
Param(
[Parameter( Mandatory = $true)]
$printName = "Joe"
)
Write-Host $printName
How to call the file
Param(
[Parameter( Mandatory = $false)]
$name = "Joe"
)
& ((Split-Path $MyInvocation.InvocationName) + "\PrintName.ps1") -printName $name
If you do not do not provide any input it will default to "Joe" and this will be passed as argument into printName argument in PrintName.ps1 file which will in turn print out the "Joe" string
Use a background worker and read only a limited number of lines. Read more only when the user scrolls.
And try to never use ReadToEnd(). It's one of the functions that you think "why did they make it?"; it's a script kiddies' helper that goes fine with small things, but as you see, it sucks for large files...
Those guys telling you to use StringBuilder need to read the MSDN more often:
Performance Considerations
The Concat and AppendFormat methods both concatenate new data to an existing String or StringBuilder object. A String object concatenation operation always creates a new object from the existing string and the new data. A StringBuilder object maintains a buffer to accommodate the concatenation of new data. New data is appended to the end of the buffer if room is available; otherwise, a new, larger buffer is allocated, data from the original buffer is copied to the new buffer, then the new data is appended to the new buffer.
The performance of a concatenation operation for a String or StringBuilder object depends on how often a memory allocation occurs.
A String concatenation operation always allocates memory, whereas a StringBuilder concatenation operation only allocates memory if the StringBuilder object buffer is too small to accommodate the new data. Consequently, the String class is preferable for a concatenation operation if a fixed number of String objects are concatenated. In that case, the individual concatenation operations might even be combined into a single operation by the compiler. A StringBuilder object is preferable for a concatenation operation if an arbitrary number of strings are concatenated; for example, if a loop concatenates a random number of strings of user input.
That means huge allocation of memory, what becomes large use of swap files system, that simulates sections of your hard disk drive to act like the RAM memory, but a hard disk drive is very slow.
The StringBuilder option looks fine for who use the system as a mono-user, but when you have two or more users reading large files at the same time, you have a problem.
I had to do something like this
CREATE OR REPLACE FUNCTION MYFUNC()

map
doesn't relate to a Cartesian product at all, although I imagine someone well versed in functional programming could come up with some impossible to understand way of generating a one using map
.
map
in Python 3 is equivalent to this:
def map(func, iterable):
for i in iterable:
yield func(i)
and the only difference in Python 2 is that it will build up a full list of results to return all at once instead of yield
ing.
Although Python convention usually prefers list comprehensions (or generator expressions) to achieve the same result as a call to map
, particularly if you're using a lambda expression as the first argument:
[func(i) for i in iterable]
As an example of what you asked for in the comments on the question - "turn a string into an array", by 'array' you probably want either a tuple or a list (both of them behave a little like arrays from other languages) -
>>> a = "hello, world"
>>> list(a)
['h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd']
>>> tuple(a)
('h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd')
A use of map
here would be if you start with a list of strings instead of a single string - map
can listify all of them individually:
>>> a = ["foo", "bar", "baz"]
>>> list(map(list, a))
[['f', 'o', 'o'], ['b', 'a', 'r'], ['b', 'a', 'z']]
Note that map(list, a)
is equivalent in Python 2, but in Python 3 you need the list
call if you want to do anything other than feed it into a for
loop (or a processing function such as sum
that only needs an iterable, and not a sequence). But also note again that a list comprehension is usually preferred:
>>> [list(b) for b in a]
[['f', 'o', 'o'], ['b', 'a', 'r'], ['b', 'a', 'z']]
You are trying to assign an array to ngClass, but the syntax for the array elements is wrong since you separate them with a ||
instead of a ,
.
Try this:
<section [ngClass]="[menu1 ? 'class1' : '', menu2 ? 'class1' : '', (something && (menu1 || menu2)) ? 'class2' : '']">
This other option should also work:
<section [ngClass.class1]="menu1 || menu2" [ngClass.class2] = "(menu1 || menu2) && something">
NDepend was already mentioned by Jesse (if you analyze .NET code) but let's explain exactly how it can help.
Is there a program/script that can scan an executable for DLL dependencies or execute the program in a "clean" DLL-free environment for testing to prevent these oops situations?
In the NDepend Project Properties panel, you can define what application assemblies to analyze (in green) and NDepend will infer Third-Party assemblies used by application ones (in blue). A list of directories where to search application and third-party assemblies is provided.
If a third-party assembly is not found in these directories, it will be in error mode. For example, if I remove the .NET Fx directory C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319
, I can see that .NET Fx third-party assemblies are not resolved:
Disclaimer: I work for NDepend
In my opinion the easiest and fastest way to get a Google Drive file ID is from Google Drive on the web. Right-click the file name and select Get shareable link. The last part of the link is the file ID. Then you can cancel the sharing.
Assuming you are using this plugin, you are misusing the .set
method. .set
must be passed the name of the key as a string as well as the value. I suppose you meant to write:
$.session.set("userName", $("#uname").val());
This sets the userName
key in session storage to the value of the input, and allows you to retrieve it using:
$.session.get('userName');
You can do it by using display:table;
in parent div and display: table-cell; vertical-align: middle;
in child div
<div style="display:table;">_x000D_
<div style="text-align: left; height: 56px; background-color: pink; display: table-cell; vertical-align: middle;">_x000D_
<div style="background-color: lightblue; ">test</div>_x000D_
</div>_x000D_
</div>

It's also worth noting that nowadays, there's less good reason to check for explicit orientation with getResources().getConfiguration().orientation
if you're doing so for layout reasons, as Multi-Window Support introduced in Android 7 / API 24+ could mess with your layouts quite a bit in either orientation. Better to consider using <ConstraintLayout>
, and alternative layouts dependent on available width or height, along with other tricks for determining which layout is being used, e.g. the presence or not of certain Fragments being attached to your Activity.
Assuming you have people is List of object
Map<String, String> phoneBook=people.stream()
.collect(toMap(Person::getName, Person::getAddress));
Now you need two steps :
1)
people =removeDuplicate(people);
2)
Map<String, String> phoneBook=people.stream()
.collect(toMap(Person::getName, Person::getAddress));
Here is method to remove duplicate
public static List removeDuplicate(Collection<Person> list) {
if(list ==null || list.isEmpty()){
return null;
}
Object removedDuplicateList =
list.stream()
.distinct()
.collect(Collectors.toList());
return (List) removedDuplicateList;
}

To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, you will create and use a hidden directory in your home directory.
Back up your computer. On the command line, in your home directory, create a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
In your preferred text editor, open or create a
~/.profile
file and add this line:
export PATH=~/.npm-global/bin:$PATH
On the command line, update your system variables:
source ~/.profile
To test your new configuration, install a package globally without using sudo
The return
statement exits a function from anywhere within the function:
function something(x)
{
if (x >= 10)
// this leaves the function if x is at least 10.
return;
// this message displays only if x is less than 10.
alert ("x is less than 10!");
}
Two points come to mind:
Security (but as long as you generate the string to be evaluated yourself, this might be a non-issue)
Performance: until the code to be executed is unknown, it cannot be optimized. (about javascript and performance, certainly Steve Yegge's presentation)
I use
decimal Debitvalue = 1156.547m;
decimal DEBITAMT = Convert.ToDecimal(string.Format("{0:F2}", Debitvalue));
Tried to do the solution with:
body {
overflow-y: scroll;
}
But I ended up with two scrollbars in Firefox in this case. So I recommend to use it on the html element like this:
html {
overflow-y: scroll;
}
From the documentation
Note that
filter(function, iterable)
is equivalent to[item for item in iterable if function(item)]
In python3, rather than returning a list; filter, map return an iterable. Your attempt should work on python2 but not in python3
Clearly, you are getting a filter object, make it a list.
shesaid = list(filter(greetings(), ["hello", "goodbye"]))
Use where_in()
$ids = array('20', '15', '22', '46', '86');
$this->db->where_in('id', $ids );
Try setting its position
to absolute. That takes it out of the flow of the document.
BTW you can pass the error message directly to sys.exit:
if len(sys.argv) < 2:
sys.exit('Usage: %s database-name' % sys.argv[0])
if not os.path.exists(sys.argv[1]):
sys.exit('ERROR: Database %s was not found!' % sys.argv[1])
You have two ways to enable it.
First, you can set the absolute path of the php module file in your httpd.conf file like this:
LoadModule php5_module /path/to/mods-available/libphp5.so
Second, you can link the module file to the mods-enabled directory:
ln -s /path/to/mods-available/libphp5.so /path/to/mods-enabled/libphp5.so
It depends a bit on context. Cardinality means the number of something but it gets used in a variety of contexts.
PERSON
table, for example, GENDER
is likely to be a very low cardinality column (there are probably only two values in GENDER
) while PERSON_ID
is likely to be a very high cardinality column (every row will have a different value).There are probably other situations where people talk about cardinality using a different context and mean something else.
This is what constructors are for! Override the model's initialize
method.
Use the after_initialize
method.
Anonymous ftp logins are usually the username 'anonymous' with the user's email address as the password. Some servers parse the password to ensure it looks like an email address.

Steps to resolve conflict:
"git checkout "MAIN_BRANCH"
"git merge origin/BRANCH_NAME_TO_BE_MERGED"
Auto-merging src/file1.py
CONFLICT (content): Merge conflict in src/file1.py
Auto-merging src/services/docker/filexyz.py
Auto-merging src/cache.py
Auto-merging src/props.py
CONFLICT (content): Merge conflict in src/props.py
Auto-merging src/app.py
CONFLICT (content): Merge conflict in src/app.py
Auto-merging file3
CONFLICT (content): Merge conflict in file3
Automatic merge failed; fix conflicts and then commit the result.
Now you can see it is showing "CONFLICT (content)", to those file which is having "CONFLICT", see your code and resolve them
Unmerged paths:
(use "git add <file>..." to mark resolution)
both modified: file3
both modified: src/app.py
both modified: src/props.py
both modified: src/utils/file1.py
git add file3
git add src/app.py
git add src/props.py
git add src/utils/file1.py

1.Load the jQuery loadScroll plugin after jQuery library, but before the closing body tag.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script><script src="jQuery.loadScroll.js"></script>
2.Add the images into your webpage using Html5 data-src attribute. You can also insert placeholders using the regular img's src attribute.
<img data-src="1.jpg" src="Placeholder.jpg" alt="Image Alt"><img data-src="2.jpg" src="Placeholder.jpg" alt="Image Alt"><img data-src="3.jpg" src="Placeholder.jpg" alt="Image Alt">
3.Call the plugin on the img tags and specify the duration of the fadeIn effect as your images are come into view
$('img').loadScroll(500); // in ms
In XAML, add and define a RowStyle Property for the DataGrid with a goal to set the Background of the Row, to the Color defined in my Employee Object.
<DataGrid AutoGenerateColumns="False" ItemsSource="EmployeeList">
<DataGrid.RowStyle>
<Style TargetType="DataGridRow">
<Setter Property="Background" Value="{Binding ColorSet}"/>
</Style>
</DataGrid.RowStyle>
And in my Employee Class
public class Employee {
public int Id { get; set; }
public string Name { get; set; }
public int Age { get; set; }
public string ColorSet { get; set; }
public Employee() { }
public Employee(int id, string name, int age)
{
Id = id;
Name = name;
Age = age;
if (Age > 50)
{
ColorSet = "Green";
}
else if (Age > 100)
{
ColorSet = "Red";
}
else
{
ColorSet = "White";
}
}
}
This way every Row of the DataGrid has the BackGround Color of the ColorSet
Property of my Object.
In an Instant App activity of a non-base feature you can call R.id.fromFeatureOne
and R.is.fromFeatureTwo
. So items from different resources are referred as of a single resource origin.
Both will be highlighted as acceptable and you can even jump to source. But build will result in an error: "cannot find symbol R.id" which is quite tricky to find the reason, as nothing is highlighted.
The solution is to call com.example.feature.one.R.is.fromFeatureOne
and com.example.feature.two.R.is.fromFeatureTwo
.

using return false in an onclick event stops the browser from processing the rest of the execution stack, which includes following the link in the href attribute.
In other words, adding return false stops the href from working. In your example, this is exactly what you want.
In buttons, it's not necessary because onclick is all it will ever execute -- there is no href to process and go to.

Code snippet above provides incorrect byte order in string, so I fixed it a bit.
char const hex[16] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B','C','D','E','F'};
std::string byte_2_str(char* bytes, int size) {
std::string str;
for (int i = 0; i < size; ++i) {
const char ch = bytes[i];
str.append(&hex[(ch & 0xF0) >> 4], 1);
str.append(&hex[ch & 0xF], 1);
}
return str;
}
There are two problems on our way to the absolute path:
The following code will give us all useful paths:
URL localPackage = this.getClass().getResource("");
URL urlLoader = YourClassName.class.getProtectionDomain().getCodeSource().getLocation();
String localDir = localPackage.getPath();
String loaderDir = urlLoader.getPath();
System.out.printf("loaderDir = %s\n localDir = %s\n", loaderDir, localDir);
Here both functions that can be used for localization of the resource folder are researched. As for class
, it can be got in either way, statically or dynamically.
If the project is not in the plugin, the code if run in JUnit, will print:
loaderDir = /C:.../ws/source.dir/target/test-classes/
localDir = /C:.../ws/source.dir/target/test-classes/package/
So, to get to src/rest/resources we should go up and down the file tree. Both methods can be used. Notice, we can't use getResource(resourceFolderName)
, for that folder is not in the target folder. Nobody puts resources in the created folders, I hope.
If the class is in the package that is in the plugin, the output of the same test will be:
loaderDir = /C:.../ws/plugin/bin/
localDir = /C:.../ws/plugin/bin/package/
So, again we should go up and down the folder tree.
The most interesting is the case when the package is launched in the plugin. As JUnit plugin test, for our example. The output is:
loaderDir = /C:.../ws/plugin/
localDir = /package/
Here we can get the absolute path only combining the results of both functions. And it is not enough. Between them we should put the local path of the place where the classes packages are, relatively to the plugin folder. Probably, you will have to insert something as src
or src/test/resource
here.
You can insert the code into yours and see the paths that you have.
Both JBoss and Tomcat are Java servlet application servers, but JBoss is a whole lot more. The substantial difference between the two is that JBoss provides a full Java Enterprise Edition (Java EE) stack, including Enterprise JavaBeans and many other technologies that are useful for developers working on enterprise Java applications.
Tomcat is much more limited. One way to think of it is that JBoss is a Java EE stack that includes a servlet container and web server, whereas Tomcat, for the most part, is a servlet container and web server.
FYI, you can compose conditional operators
var a = (truthy) ? 1 : (falsy) ? 2 : 3;
If your logic is sufficiently complex, then you might consider using an IIFE
var a = (function () {
if (truthy) return 1;
else if (falsy) return 2;
return 3;
})();
Of course, if you plan to use this logic more than once, then you aught to encapsulate it in a function to keep things nice and DRY.
If you are on MAC Install this globally

pip3 install MySQL-Python

This is because require()
does not exist in the browser/client-side JavaScript.
Now you're going to have to make some choices about your client-side JavaScript script management.
You have three options:
<script>
tag.CommonJS client side-implementations include (most of them require a build step before you deploy):
You can read more about my comparison of Browserify vs (deprecated) Component.
AMD implementations include:
Note, in your search for choosing which one to go with, you'll read about Bower. Bower is only for package dependencies and is unopinionated on module definitions like CommonJS and AMD.
boolean x;
for (x = false,
map.put("One", new Integer(1)),
map.put("Two", new Integer(2)),
map.put("Three", new Integer(3)); x;);
Ignoring the declaration of x
(which is necessary to avoid an "unreachable statement" diagnostic), technically it's only one statement.
I solved this issue by doing the following:
When using ECMAScript 6 modules from the browser, use the .js extension in your files and in the script tag add type = "module"
.
When using ECMAScript 6 modules from a Node.js environment, use the extension .mjs
in your files and use this command to run the file:
node --experimental-modules filename.mjs

This is a way to create tables dynamically using T-SQL stored procedures:

set @cmd = 'CREATE TABLE dbo.' + quotename(@MyTableName, '[') + '(ColumnName1 int not null,ColumnName2 int not null);';
Execute it as:
exec(@cmd);
^ BRANCH Selector
git checkout HEAD^2
Selects the 2nd branch of a (merge) commit by moving onto the selected branch (one step backwards on the commit-tree)
~ COMMIT Selector
git checkout HEAD~2
Moves 2 commits backwards on the default/selected branch
Defining both ~ and ^ relative refs as PARENT selectors is far the dominant definition published everywhere on the internet I have come across so far - including the official Git Book. Yes they are PARENT selectors, but the problem with this "explanation" is that it is completely against our goal: which is how to distinguish the two... :)
The other problem is when we are encouraged to use the ^ BRANCH selector for COMMIT selection (aka HEAD^ === HEAD~).
Again, yes, you can use it this way, but this is not its designed purpose. The ^ BRANCH selector's backwards move behaviour is a side effect not its purpose.
At merged commits only, can a number be assigned to the ^ BRANCH selector. Thus its full capacity can only be utilised where there is a need for selecting among branches. And the most straightforward way to express a selection in a fork is by stepping onto the selected path / branch - that's for the one step backwards on the commit-tree. It is a side effect only, not its main purpose.

I have a case where I am transforming a legacy DB2 z/os database timestamp (formatted as: "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
) into a SqlServer 2016 datetime2 (formatted as: "yyyy-MM-dd HH:mm:ss.SSS
) field that is handled by our Spring/Hibernate Entity Manager instance (in this case, the OldRevision Table). In the Class, I define the date as the java.util
type, and write the setter and getter in the normal way. Then, When handling the data, the code I have handling the data related to this question looks like this:
OldRevision revision = new OldRevision();
String oldRevisionDateString= oldRevisionData.getString("originalRevisionDate", "");
Date oldDateFormat = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ");
oldDateFormat.parse(oldRevisionDateString);
SimpleDateFormat newDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
newDateFormat.setTimeZone(TimeZone.getTimeZone("EST"));
Date finalFormattedDate= newDateFormat.parse(newDateFormat.format(oldDateFormat));
revision.setOriginalRevisionDate(finalFormattedDate);
em.persist(revision);
A simpler way to do the same case is:
SimpleDateFormat newDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
newDateFormat.setTimeZone(TimeZone.getTimeZone("EST"));
revision.setOriginalRevisionDate(
newDateFormat.parse(newDateFormat.format(
new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ")
.parse(rs.getString("originalRevisionDate", "")))));

1. How can I completely avoid reverse engineering of an Android APK? Is this possible?
That is impossible
2. How can I protect all the app's resources, assets and source code so that hackers can't hack the APK file in any way?
Developers can take steps such as using tools like ProGuard to obfuscate their code, but up until now, it has been quite difficult to completely prevent someone from decompiling an app.
It's a really great tool and can increase the difficulty of 'reversing' your code whilst shrinking your code's footprint.
Integrated ProGuard support: ProGuard is now packaged with the SDK Tools. Developers can now obfuscate their code as an integrated part of a release build.
3. Is there a way to make hacking more tough or even impossible? What more can I do to protect the source code in my APK file?
While researching, I came to know about HoseDex2Jar. This tool will protect your code from decompiling, but it seems not to be possible to protect your code completely.
Some of helpful links, you can refer to them.
My async function
const getAllRedis = async (key) => {
let obj = [];
await client.hgetall(key, (err, object) => {

})
return obj;
// res.send(obj);
});
}
You can't free types that aren't dynamically allocated. Although arrays are syntactically similar (int* x = malloc(sizeof(int) * 4)
can be used in the same way that int x[4]
is), calling free(firstName)
would likely cause an error for the latter.
For example, take this code:
int x;
free(&x);
free()
is a function which takes in a pointer. &x
is a pointer. This code may compile, even though it simply won't work.
If we pretend that all memory is allocated in the same way, x
is "allocated" at the definition, "freed" at the second line, and then "freed" again after the end of the scope. You can't free the same resource twice; it'll give you an error.
This isn't even mentioning the fact that for certain reasons, you may be unable to free the memory at x
without closing the program.
tl;dr: Just free the struct
and you'll be fine. Don't call free on arrays; only call it on dynamically allocated memory.
Hai Vu answer works great, just one comment:
In case you are using the global in other module and you want to set the global dynamically, pay attention to import the other modules after you set the global variables, for example:
# settings.py
def init(arg):
global myList
myList = []
mylist.append(arg)
# subfile.py
import settings
def print():
settings.myList[0]
# main.py
import settings
settings.init("1st") # global init before used in other imported modules
# Or else they will be undefined
import subfile
subfile.print() # global usage
It's really hard to tell, but one of the 9001 ads on the page may be clobbering the $
object.
jQuery provides the global jQuery
object (which is present on your page). You can do the following to "get" $
back:
jQuery(document).ready(function ($) {
// Your code here
});
If you think you're having jQuery problems, please use the debug (non-production) versions of the library.
Also, it's probably not best to be editing a live site like that ...
SQLite has a printf
function which does exactly that:
SELECT printf('%s-%.2d-%.4d', col1, col2, col3) FROM mytable
To activate the menus and submenus, even with params in the URL, use the code bellow:
// Highlight the active menu
$(document).ready(function () {
var action = window.location.pathname.split('/')[1];
// If there's no action, highlight the first menu item
if (action == "") {
$('ul.nav li:first').addClass('active');
} else {
// Highlight current menu
$('ul.nav a[href="/' + action + '"]').parent().addClass('active');
// Highlight parent menu item
$('ul.nav a[href="/' + action + '"]').parents('li').addClass('active');
}
});
This accepts URLs like:
/posts
/posts/1
/posts/1/edit
class FooObservableCollection : ObservableCollection<Foo>
{
protected override void InsertItem(int index, Foo item)
{
base.Add(index, Foo);
if (this.CollectionChanged != null)
this.CollectionChanged(this, new NotifyCollectionChangedEventArgs (NotifyCollectionChangedAction.Add, item, index);
}
}
var collection = new FooObservableCollection();
collection.CollectionChanged += CollectionChanged;
collection.Add(new Foo());
void CollectionChanged (object sender, NotifyCollectionChangedEventArgs e)
{
Foo newItem = e.NewItems.OfType<Foo>().First();
}
Add newWin.document.close();, like so:
function printDiv() {
var divToPrint = document.getElementById('printArea');
var newWin = window.open();
newWin.document.write(divToPrint.innerHTML);
newWin.document.close();
newWin.print();
newWin.close();
}
This makes IE happy. HTH, -Ted
import java.util.Date;
import java.text.SimpleDateFormat;
...
Date currentMonth = new Date();
String yyyyMM = new SimpleDateFormat("yyyyMM").format(currentMonth);
Date firstDateOfMonth = new SimpleDateFormat("yyyyMM").parse(yyyyMM);
...
my stupid solution. but it's work for me :D
The best way is not to write any initializing statements. This is because if you write
int a[]=new int[3]
then by default, in Java all the values of array i.e. a[0]
, a[1]
and a[2]
are initialized to 0
! Regarding the local variable hiding a field, post your entire code for us to come to conclusion.
If you want to save a file to a particular DIRECTORY and FILENAME here is some simple example. It also checks to see if the directory has or has not been created.
import os.path
directory = './html/'
filename = "file.html"
file_path = os.path.join(directory, filename)
if not os.path.isdir(directory):
os.mkdir(directory)
file = open(file_path, "w")
file.write(html)
file.close()
Hope this helps you!
The dangling images are ghosts from the previous builds and pulls, simply delete them with : docker rmi $(docker images -f "dangling=true" -q)
Best thing to use is HTMLAgilityPack. You can also look into using Fizzler or CSQuery depending on your needs for selecting the elements from the retrieved page. Using LINQ or Regukar Expressions is just to error prone, especially when the HTML can be malformed, missing closing tags, have nested child elements etc.
You need to stream the page into an HtmlDocument object and then select your required element.
// Call the page and get the generated HTML
var doc = new HtmlAgilityPack.HtmlDocument();
HtmlAgilityPack.HtmlNode.ElementsFlags["br"] = HtmlAgilityPack.HtmlElementFlag.Empty;
doc.OptionWriteEmptyNodes = true;
try
{
var webRequest = HttpWebRequest.Create(pageUrl);
Stream stream = webRequest.GetResponse().GetResponseStream();
doc.Load(stream);
stream.Close();
}
catch (System.UriFormatException uex)
{
Log.Fatal("There was an error in the format of the url: " + itemUrl, uex);
throw;
}
catch (System.Net.WebException wex)
{
Log.Fatal("There was an error connecting to the url: " + itemUrl, wex);
throw;
}
//get the div by id and then get the inner text
string testDivSelector = "//div[@id='test']";
var divString = doc.DocumentNode.SelectSingleNode(testDivSelector).InnerHtml.ToString();
[EDIT] Actually, scrap that. The simplest method is to use FizzlerEx, an updated jQuery/CSS3-selectors implementation of the original Fizzler project.
Code sample directly from their site:
using HtmlAgilityPack;
using Fizzler.Systems.HtmlAgilityPack;
//get the page
var web = new HtmlWeb();
var document = web.Load("http://example.com/page.html");
var page = document.DocumentNode;
//loop through all div tags with item css class
foreach(var item in page.QuerySelectorAll("div.item"))
{
var title = item.QuerySelector("h3:not(.share)").InnerText;
var date = DateTime.Parse(item.QuerySelector("span:eq(2)").InnerText);
var description = item.QuerySelector("span:has(b)").InnerHtml;
}
I don't think it can get any simpler than that.
This is because of ng-include
which creates a new child scope, so $scope.lineText
isn’t changed. I think that this
refers to the current scope, so this.lineText
should be set.
create two tabs, one with the formulas and then a second where you paste link the entire table. the second tab should have no problems when sorting!
There is a lot of lesson to learn handcrafting state machines in C, but let me also suggest Ragel state machine compiler:
http://www.complang.org/ragel/
It has quite simple way of defining state machines and then you can generate graphs, generate code in different styles (table-driven, goto-driven), analyze that code if you want to, etc. And it's powerful, can be used in production code for various protocols.
The following answer could be helpful for the first part of your question:
I got the same error message. In my case, it was due to not using quotes.
Although the column was supposed to have only numbers, it was a Varchar column, and one of the rows had a letter in it.
So I was doing this:
select * from mytable where myid = 1234
While I should be doing this:
select * from mytable where myid = '1234'
If the column had all numbers, the conversion would have worked, but not in this case.

A simple generic function I normally use.
const promisify = (fn, ...args) => {
return new Promise((resolve, reject) => {
fn(...args, (err, data) => {
if (err) {
return reject(err);
}
resolve(data);
});
});
};
How to use it
promisify(fn, arg1, arg2)

I had no problem making EditTextPreference read-only, by using:
editTextPref.setSelectable(false);
This works well when coupled with using the 'summary' field to display read-only fields (useful for displaying account info, for example). Updating the summary fields dynamically snatched from http://gmariotti.blogspot.com/2013/01/preferenceactivity-preferencefragment.html
private static final List<String> keyList;
static {
keyList = new ArrayList<String>();
keyList.add("field1");
keyList.add("field2");
keyList.add("field3");
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
for(int i=0;i<getPreferenceScreen().getPreferenceCount();i++){
initSummary(getPreferenceScreen().getPreference(i));
}
}
private void initSummary(Preference p) {
if (p instanceof PreferenceCategory) {
PreferenceCategory pCat = (PreferenceCategory) p;
for (int i = 0; i < pCat.getPreferenceCount(); i++) {
initSummary(pCat.getPreference(i));
}
} else {
updatePrefSummary(p);
}
}
private void updatePrefSummary(Preference p) {
if (p instanceof ListPreference) {
ListPreference listPref = (ListPreference) p;
p.setSummary(listPref.getEntry());
}
if (p instanceof EditTextPreference) {
EditTextPreference editTextPref = (EditTextPreference) p;
//editTextPref.setEnabled(false); // this can be used to 'gray out' as well
editTextPref.setSelectable(false);
if (keyList.contains(p.getKey())) {
p.setSummary(editTextPref.getText());
}
}
}
Looks like opencv lib is pretty sensitive to parameters passed to the methods. The following code worked for me using opencv 4.3.0:
win_name = "visualization" # 1. use var to specify window name everywhere
cv2.namedWindow(win_name, cv2.WINDOW_NORMAL) # 2. use 'normal' flag
img = cv2.imread(filename)
h,w = img.shape[:2] # suits for image containing any amount of channels
h = int(h / resize_factor) # one must compute beforehand
w = int(w / resize_factor) # and convert to INT
cv2.resizeWindow(win_name, w, h) # use variables defined/computed BEFOREHAND
cv2.imshow(win_name, img)

I have tried using php -l
and a couple of other tools.
However, the best one in my experience (your mileage may vary, of course) is scheck of pfff toolset. I heard about pfff on Quora (Is there a good PHP lint / static analysis tool?).
You can compile and install it. There are no nice packages (on my Linux Mint Debian system, I had to install the libpcre3-dev, ocaml, libcairo-dev, libgtk-3-dev and libgimp2.0-dev dependencies first) but it should be worth an install.
The results are reported like
$ ~/sw/pfff/scheck ~/code/github/sc/
login-now.php:7:4: CHECK: Unused Local variable $title
go-automatic.php:14:77: CHECK: Use of undeclared variable $goUrl.
I literally did this 1 hour ago.
Download the appropriate files for your OS. The Android SDK needs java in order to install. Once you get the Android SDK installed go get eclipse and install that. Basically download the file and unzip then in a directory. The android install is the same but it will install a lot more files. (5) Finally open eclipse and go to help > install new software >> and add the url to the plugin - I used this one https://dl-ssl.google.com/android/eclipse/

Warning! $array1 + $array2 overwrites keys, so my solution (for multidimensional arrays) is to use array_unique()
array_unique(array_merge($a, $b), SORT_REGULAR);
Notice:
5.2.10+ Changed the default value of
sort_flags
back to SORT_STRING.5.2.9 Default is SORT_REGULAR.
5.2.8- Default is SORT_STRING
It perfectly works. Hope it helps same.
I just had this error message happen. When searching for why, I figured out that there's a related issue that can occur if you're not paying attention - the same error occurs if the directory you are trying to move into does not exist.
Here is another alternative for adding leading to 0s to strings such as CUSIPs which can sometimes look like a number and which many applications such as Excel will corrupt and remove the leading 0s or convert them to scientific notation.
When I tried the answer provided by @metasequoia the vector returned had leading spaces and not 0
s. This was the same problem mentioned by @user1816679 -- and removing the quotes around the 0
or changing from %d
to %s
did not make a difference either. FYI, I am using RStudio Server running on an Ubuntu Server. This little two-step solution worked for me:
gsub(pattern = " ", replacement = "0", x = sprintf(fmt = "%09s", ids[,CUSIP]))
using the %>%
pipe function from the magrittr
package it could look like this:
sprintf(fmt = "%09s", ids[,CUSIP]) %>% gsub(pattern = " ", replacement = "0", x = .)
I'd prefer a one-function solution, but it works.
Table creation Syntax can be like:
Create table api_key(api_key_id INT NOT NULL IDENTITY(1,1)
PRIMARY KEY, date_added date DEFAULT
GetDate());
Insertion query syntax can be like:
Insert into api_key values(GETDATE());
Ok, so after running in the same issue, I have found a Solution.
This is what I did:
Step 1: Open ESET. Then click on Setup
Step 2: Click on Network protection
Step 3: Click on Troubleshooting wizard
Step 4: Find the Communication 10.0.75.2 (Default docker IP setting) Just check what the IP Range is defined inside your docker settings. Then look for for the IP which resides in that range.
Step 5: Click on the Unblock button, then you should receive this screen.
This solved the issue for myself.
You can then go to the Rules and check the rule that was added.
PS: This is my first post, sorry for any incorrect procedures.
You can use a bind variable at the SQLPlus level to do this. Of course you have little control over the formatting of the output.

EXEC GetGrantListByPI(args, :x);
PRINT x;
Use component scanning as given below, if com.project.action.PasswordHintAction
is annotated with stereotype annotations
<context:component-scan base-package="com.project.action"/>
EDIT
I see your problem, in PasswordHintActionTest
you are autowiring PasswordHintAction
. But you did not create bean configuration for PasswordHintAction
to autowire. Add one of stereotype annotation(@Component, @Service, @Controller
) to PasswordHintAction
like
@Component
public class PasswordHintAction extends BaseAction {
private static final long serialVersionUID = -4037514607101222025L;
private String username;
or create xml configuration in applicationcontext.xml
like
<bean id="passwordHintAction" class="com.project.action.PasswordHintAction" />
Try this:
$(":focus").each(function() {
alert("Focused Elem_id = "+ this.id );
});
My friend Brian wrote a comprehensive article on this. I think it is a great intro to how to use topics. https://www.brianstorti.com/vim-registers/
There is also another possible source of this error. In some J2EE / web containers (in my experience under Jboss 7.x and Tomcat 7.x) You have to add each class You want to use as a hibernate Entity into the file persistence.xml as
<class>com.yourCompanyName.WhateverEntityClass</class>
In case of jboss this concerns every entity class (local - i.e. within the project You are developing or in a library). In case of Tomcat 7.x this concerns only entity classes within libraries.
1 - (change)
is bound to the HTML onchange event. The documentation about HTML onchange says the following :
Execute a JavaScript when a user changes the selected option of a
<select>
element
Source : https://www.w3schools.com/jsref/event_onchange.asp
2 - As stated before, (ngModelChange)
is bound to the model variable binded to your input.
So, my interpretation is :
(change)
triggers when the user changes the input(ngModelChange)
triggers when the model changes, whether it's consecutive to a user action or notYou will want to use the YYYYMMDD for unambiguous date determination in SQL Server.

here is the style for Italian dates. Well, not just Italians, but that's the culture it's attributed to in Books Online.
I don't think there is a way to do that out-of-the-box. A possibly cleaner solution would be:
Stream.of(objects)
.filter(c -> c instanceof Client)
.map(c -> (Client) c)
.map(Client::getID)
.forEach(System.out::println);
or, as suggested in the comments, you could use the cast
method - the former may be easier to read though:
Stream.of(objects)
.filter(Client.class::isInstance)
.map(Client.class::cast)
.map(Client::getID)
.forEach(System.out::println);
Ideally, have a keyword table containing the fields:
Keyword
Id
Count (possibly)
with an index on Keyword. Create an insert/update/delete trigger on the other table so that, when a row is changed, every keyword is extracted and put into (or replaced in) this table.
You'll also need a table of words to not count as keywords (if, and, so, but, ...).
In this way, you'll get the best speed for queries wanting to look for the keywords and you can implement (relatively easily) more complex queries such as "contains Java and RCA1802".
"LIKE"
queries will work but they won't scale as well.
You can also use the CSS calc() function to subtract the width of your padding from the percentage of your container's width.
An example:
width: calc((100%) - (32px))
Just be sure to make the subtracted width equal to the total padding, not just one half. If you pad both sides of the inner div with 16px, then you should subtract 32px from the final width, assuming that the example below is what you want to achieve.
.outer {_x000D_
width: 200px;_x000D_
height: 120px;_x000D_
background-color: black;_x000D_
}_x000D_
_x000D_
.inner {_x000D_
height: 40px;_x000D_
top: 30px;_x000D_
position: relative;_x000D_
padding: 16px;_x000D_
background-color: teal;_x000D_
}_x000D_
_x000D_
#inner-1 {_x000D_
width: 100%;_x000D_
}_x000D_
_x000D_
#inner-2 {_x000D_
width: calc((100%) - (32px));_x000D_
}
_x000D_
<div class="outer" id="outer-1">_x000D_
<div class="inner" id="inner-1"> width of 100% </div>_x000D_
</div>_x000D_
_x000D_
<br>_x000D_
<br>_x000D_
_x000D_
<div class="outer" id="outer-2">_x000D_
<div class="inner" id="inner-2"> width of 100% - 16px </div>_x000D_
</div>
_x000D_
The basic difference is:
int i = Console.Read();
Console.WriteLine(i);
paste above code and give input 'c', and the output will be 99. That is Console.Read give int value but that value will be the ASCII value of that..
On the other side..
string s = Console.ReadLine();
Console.WriteLine(s);
It gives the string as it is given in the input stream.
You can turn off the "Disable Script Debugging"
option inside of Internet Explorer and start debugging with Visual Studio
if you happen to have that around.
I've found that it is one of few ways to diagnose some of those IE

This will give you the gridview row index for the value:
String searchValue = "somestring";
int rowIndex = -1;
foreach(DataGridViewRow row in DataGridView1.Rows)
{
if(row.Cells[1].Value.ToString().Equals(searchValue))
{
rowIndex = row.Index;
break;
}
}
Or a LINQ query
int rowIndex = -1;
DataGridViewRow row = dgv.Rows
.Cast<DataGridViewRow>()
.Where(r => r.Cells["SystemId"].Value.ToString().Equals(searchValue))
.First();
rowIndex = row.Index;
then you can do:
dataGridView1.Rows[rowIndex].Selected = true;
See: http://jsfiddle.net/thirtydot/cMNX2/8/

}
A simpler way to wait is to use System.currentTimeMillis()
, which returns the number of milliseconds since midnight on January 1, 1970 UTC. For example, to wait 5 seconds:
public static void main(String[] args) {
//some code
long original = System.currentTimeMillis();
while (true) {
if (System.currentTimeMillis - original >= 5000) {
break;
}
}
//more code after waiting
}
This way, you don't have to muck about with threads and exceptions. Hope this helps!
A simple way of generating a printable report from a Datagridview is to place the datagridview on a Panel object. It is possible to draw a bitmap of the panel.
Here's how I do it.
'create the bitmap with the dimentions of the Panel Dim bmp As New Bitmap(Panel1.Width, Panel1.Height)
'draw the Panel to the bitmap "bmp" Panel1.DrawToBitmap(bmp, Panel1.ClientRectangle)
I create a multi page tiff by "breaking my datagridview items into pages. this is how i detect the start of a new page:
'i add the rows to my datagrid one at a time and then check if the scrollbar is active. 'if the scrollbar is active i save the row to a variable and then i remove it from the 'datagridview and roll back my counter integer by one(thus the next run will include this 'row.
Private Function VScrollBarVisible() As Boolean
Dim ctrl As New Control
For Each ctrl In DataGridView_Results.Controls
If ctrl.GetType() Is GetType(VScrollBar) Then
If ctrl.Visible = True Then
Return True
Else
Return False
End If
End If
Next
Return Nothing
End Function
I hope this helps
you could JSONObject#has
, providing the key
as input and check if the method returns true
or false
. You could also
use optString
instead of getString
:
Returns the value mapped by name if it exists, coercing it if necessary. Returns the empty string if no such mapping exists
A Bash function can't return a string directly like you want it to. You can do three things:
This is also true for some other shells.
Here's how to do each of those options:
lockdir="somedir"
testlock(){
retval=""
if mkdir "$lockdir"
then # Directory did not exist, but it was created successfully
echo >&2 "successfully acquired lock: $lockdir"
retval="true"
else
echo >&2 "cannot acquire lock, giving up on $lockdir"
retval="false"
fi
echo "$retval"
}
retval=$( testlock )
if [ "$retval" == "true" ]
then
echo "directory not created"
else
echo "directory already created"
fi
lockdir="somedir"
testlock(){
if mkdir "$lockdir"
then # Directory did not exist, but was created successfully
echo >&2 "successfully acquired lock: $lockdir"
retval=0
else
echo >&2 "cannot acquire lock, giving up on $lockdir"
retval=1
fi
return "$retval"
}
testlock
retval=$?
if [ "$retval" == 0 ]
then
echo "directory not created"
else
echo "directory already created"
fi
lockdir="somedir"
retval=-1
testlock(){
if mkdir "$lockdir"
then # Directory did not exist, but it was created successfully
echo >&2 "successfully acquired lock: $lockdir"
retval=0
else
echo >&2 "cannot acquire lock, giving up on $lockdir"
retval=1
fi
}
testlock
if [ "$retval" == 0 ]
then
echo "directory not created"
else
echo "directory already created"
fi
You can also try this one as well with data-myTag
<select id="location">
<option value="a" data-myTag="123">My option</option>
<option value="b" data-myTag="456">My other option</option>
</select>
<input type="hidden" id="setMyTag" />
<script>
$(function() {
$("#location").change(function(){
var myTag = $('option:selected', this).data("myTag");
$('#setMyTag').val(myTag);
});
});
</script>
This is a late contribution, but there is a valid case for casting json_decode
with (array)
.
Consider the following:
$jsondata = '';
$arr = json_decode($jsondata, true);
foreach ($arr as $k=>$v){
echo $v; // etc.
}
If $jsondata
is ever returned as an empty string (as in my experience it often is), json_decode
will return NULL
, resulting in the error Warning: Invalid argument supplied for foreach() on line 3. You could add a line of if/then code or a ternary operator, but IMO it's cleaner to simply change line 2 to ...
$arr = (array) json_decode($jsondata,true);
... unless you are json_decode
ing millions of large arrays at once, in which case as @TCB13 points out, performance could be negatively effected.
Three years later, I ran into the same issue. Setting the path in user settings & PATH environment variable didn't help. I updated VSCode and that solved it.
I was getting this error though there were no (obvious) brackets in my URL, and in my situation the --globoff command will not solve the issue.
For example (doing this on on mac in iTerm2):
for endpoint in $(grep some_string output.txt); do curl "http://1.2.3.4/api/v1/${endpoint}" ; done
I have grep aliased to "grep --color=always". As a result, the above command will result in this error, with some_string highlighted in whatever colour you have grep set to:
curl: (3) bad range in URL position 31:
http://1.2.3.4/api/v1/lalalasome_stringlalala
The terminal was transparently translating the [colour\codes]some_string[colour\codes] into the expected no-special-characters URL when viewed in terminal, but behind the scenes the colour codes were being sent in the URL passed to curl, resulting in brackets in your URL.
Solution is to not use match highlighting.
erm it does work? I've just tested it?

There are three major types of cloud services: IaaS, PaaS, and SaaS. You’ve probably seen these abbreviations on the websites of cloud providers. Before going into details, let’s compare IaaS, PaaS, and SaaS to transportation:
On-premises IT infrastructure is like owning a car. When you buy a car, you’re responsible for its maintenance, and upgrading means buying a new car.
IaaS is like leasing a car. When you lease a car, you choose the car you want and drive it wherever you wish, but the car isn’t yours. Want an upgrade? Just lease a different car!
PaaS is like taking a taxi. You don’t drive a taxi yourself, but simply tell the driver where you need to go and relax in the back seat.
SaaS is like going by bus. Buses have assigned routes, and you share the ride with other passengers.

Inline code takes higher precedence than the other ones. To call your other function func () call it from the f1 ().
Inside your function, add a line,
function fun () {
// Your code here
}
function f1()
{
alert("f1 called");
//form validation that recalls the page showing with supplied inputs.
fun ();
}
Rewriting your whole code,
<!DOCTYPE html>
<html>
<head>
<script>
function fun()
{
alert("hello");
//validation code to see State field is mandatory.
}
function f1()
{
alert("f1 called");
//form validation that recalls the page showing with supplied inputs.
fun ();
}
</script>
</head>
<body>
<form name="form1" id="form1" method="post">
State: <select id="state ID">
<option></option>
<option value="ap">ap</option>
<option value="bp">bp</option>
</select>
</form>
<table><tr><td id="Save" onclick="f1()">click</td></tr></table>
</body>
</html>
You should probably re-write the script to return a value rather than output it. Instead of:
a=$( script.sh ) # Now a is a string, either "success" or "Failed"
case "$a" in
success) echo script succeeded;;
Failed) echo script failed;;
esac
you would be able to do:
if script.sh > /dev/null; then
echo script succeeded
else
echo script failed
fi
It is much simpler for other programs to work with you script if they do not have to parse the output. This is a simple change to make. Just exit 0
instead of printing success
, and exit 1
instead of printing Failed
. Of course, you can also print those values as well as exiting with a reasonable return value, so that wrapper scripts have flexibility in how they work with the script.
Maybe your firewall or a blocker application (PeerBlock etc.) is blocking your port
Use the "Edit top 200" option, then click on "Show SQL panel", modify your query with your WHERE clause, and execute the query. You'll be able to edit the results.
According to HTML5 drafts, the checked
attribute is a “boolean attribute”, and “The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.” It is the name of the attribute that matters, and suffices. Thus, to make a checkbox initially checked, you use
<input type=checkbox checked>
By default, in the absence of the checked
attribute, a checkbox is initially unchecked:
<input type=checkbox>
Keeping things this way keeps them simple, but if you need to conform to XML syntax (i.e. to use HTML5 in XHTML linearization), you cannot use an attribute name alone. Then the allowed (as per HTML5 drafts) values are the empty string and the string checked
, case insensitively. Example:
<input type="checkbox" checked="checked" />
You could initialize ReturnDate on the model before sending it to the view.
In the controller:
[HttpGet]
public ActionResult SomeAction()
{
var viewModel = new MyActionViewModel
{
ReturnDate = System.DateTime.Now
};
return View(viewModel);
}
Took some searching and reading to find a method that suited my situation, on form submit, run ajax to a remote php script, on success/failure inform user, on complete clear the form.
I had some default values, all other methods involved .val('') thereby not resetting but clearing the form.
I got this too work by adding a reset button to the form, which had an id of myform
:
$("#myform > input[type=reset]").trigger('click');
This for me had the correct outcome on resetting the form, oh and dont forget the
event.preventDefault();
to stop the form submitting in browser, like I did :).

I have used both R and MATLAB to solve problems and construct models related to Environmental Engineering and there is a lot of overlap between the two systems. In my opinion, the advantages of MATLAB lie in specialized domain-specific applications. Some examples are:
Functions such as streamline that aid in fluid dynamics investigations.
Toolboxes such as the image processing toolset. I have not found a R package that provides an equivalent implementation of tools like the watershed algorithm.
In my opinion MATLAB provides far better interactive graphics capabilities. However, I think R produces better static print-quality graphics, depending on the application. MATLAB's symbolic math toolbox is also better integrated and more capable than R equivalents such as Ryacas or rSymPy. The existence of the MATLAB compiler also allows systems based on MATLAB code to be deployed independently of the MATLAB environment-- although it's availability will depend on how much money you have to throw around.
Another thing I should note is that the MATLAB debugger is one of the best I have worked with.
The principle advantage I see with R is the openness of the system and the ease with which it can be extended. This has resulted in an incredible diversity of packages on CRAN. I know Mathworks also maintains a repository of user-contributed toolboxes and I can't make a fair comparison as I have not used it that much.
The openness of R also extends to linking in compiled code. A while back I had a model written in Fortran and I was trying to decide between using R or MATLAB as a front-end to help prepare input and process results. I spent an hour reading about the MEX interface to compiled code. When I found that I would have to write and maintain a separate Fortran routine that did some intricate pointer juggling in order to manage the interface, I shelved MATLAB.
The R interface consists of calling .Fortran( [subroutine name], [argument list]) and is simply quicker and cleaner.
The problem was in nulls in the values; then the concatenation does not work with nulls. The solution is as follows:
SELECT coalesce(a, '') || coalesce(b, '') FROM foo;
Why not use the API?
int h = 48; // height in pixels
int w = 48; // width in pixels
Bitmap scaled = Bitmap.createScaledBitmap(largeBitmap, w, h, true);
You are adding the formControlName
to the label and not the input.
You have this:
<div >
<div class="input-field col s12">
<input id="email" type="email">
<label class="center-align" for="email" formControlName="email">Email</label>
</div>
</div>
Try using this:
<div >
<div class="input-field col s12">
<input id="email" type="email" formControlName="email">
<label class="center-align" for="email">Email</label>
</div>
</div>
Update the other input fields as well.
Simply copy the file, add and commit it:
cp dir1/A.txt dir2/A.txt
git add dir2/A.txt
git commit -m "Duplicated file from dir1/ to dir2/"
Then the following commands will show the full pre-copy history:
git log --follow dir2/A.txt
To see inherited line-by-line annotations from the original file use this:
git blame -C -C -C dir2/A.txt
Git does not track copies at commit-time, instead it detects them when inspecting history with e.g. git blame
and git log
.
Most of this information comes from the answers here: Record file copy operation with Git
You need to use debug(@var)
. It's exactly like "print_r".
One easy way is to drag and drop. It will copy files to /sdcard/Download. You can copy whole folders or multiple files. Make sure that "Enable Clipboard Sharing" is enabled. (under ...->Settings)
you can use CHARINDEX
in t-sql.
select * from table where CHARINDEX(url, 'http://url.com/url?url...') > 0
#change-avatar-file
is a file input
#change-avatar-file
is a img tag (the target of jcrop)
The "key" is FR.onloadend Event
https://developer.mozilla.org/en-US/docs/Web/API/FileReader
$('#change-avatar-file').change(function(){
var currentImg;
if ( this.files && this.files[0] ) {
var FR= new FileReader();
FR.onload = function(e) {
$('#avatar-change-img').attr( "src", e.target.result );
currentImg = e.target.result;
};
FR.readAsDataURL( this.files[0] );
FR.onloadend = function(e){
//console.log( $('#avatar-change-img').attr( "src"));
var jcrop_api;
$('#avatar-change-img').Jcrop({
bgFade: true,
bgOpacity: .2,

I found mongo-connector useful. It is form Mongo Labs (MongoDB Inc.) and can be used now with Elasticsearch 2.x
Elastic 2.x doc manager: https://github.com/mongodb-labs/elastic2-doc-manager
mongo-connector creates a pipeline from a MongoDB cluster to one or more target systems, such as Solr, Elasticsearch, or another MongoDB cluster. It synchronizes data in MongoDB to the target then tails the MongoDB oplog, keeping up with operations in MongoDB in real-time. It has been tested with Python 2.6, 2.7, and 3.3+. Detailed documentation is available on the wiki.
https://github.com/mongodb-labs/mongo-connector https://github.com/mongodb-labs/mongo-connector/wiki/Usage%20with%20ElasticSearch
401 means "Unauthorized", so there must be something with your credentials.
I think that java URL
does not support the syntax you are showing. You could use an Authenticator instead.
Authenticator.setDefault(new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(login, password.toCharArray());
}
});
and then simply invoking the regular url, without the credentials.
The other option is to provide the credentials in a Header:
String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);
PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.
You can use jQuery UI and do something like this
Html:
<button id="callConfirm">Confirm!</button>
<div id="dialog" title="Confirmation Required">
Are you sure about this?
</div>?
Javascript:
$("#dialog").dialog({
autoOpen: false,
modal: true,
buttons : {
"Confirm" : function() {
alert("You have confirmed!");
},
"Cancel" : function() {
$(this).dialog("close");
}
}
});
$("#callConfirm").on("click", function(e) {
e.preventDefault();
$("#dialog").dialog("open");
});
?
You can easily do that by using lazy loading in react. For that you have to use lazy and suspense from react like that.
import React, { lazy, Suspense } from 'react';
const loadable = (importFunc, { fallback = null } = { fallback: null }) => {
const LazyComponent = lazy(importFunc);
return props => (
<Suspense fallback={fallback}>
<LazyComponent {...props} />
</Suspense>
);
};
export default loadable;
After that export your components like this.
export const TeacherTable = loadable(() =>
import ('./MainTables/TeacherTable'), {
fallback: <Loading />,
});
And then in your routes file use it like this.
<Route exact path="/app/view/teachers" component={TeacherTable} />
Thats it now you are good to go everytime your DOM is rendering your Loading compnent will be displayed as we have specified in the fallback property above. Just make sure that you do any ajax request only in componentDidMount()
This also works fine .Simple and easy.see http://jsfiddle.net/uZc8w/570/
$('#myimage').removeAttr("click");

echo.
echo The Date is %day%, %month% %date:~7,2%, %date:~10,4% the current time is: %time:~0,5%
pause
Outputs: The Date is Sunday, September 27, 2009 the current time is: 3:07

Yes, there is a way to write to the event log you are looking for. You don't need to create a new source, just simply use the existent one, which often has the same name as the EventLog's name and also, in some cases like the event log Application, can be accessible without administrative privileges*.
*Other cases, where you cannot access it directly, are the Security EventLog, for example, which is only accessed by the operating system.
I used this code to write directly to the event log Application:
using (EventLog eventLog = new EventLog("Application"))
{
eventLog.Source = "Application";
eventLog.WriteEntry("Log message example", EventLogEntryType.Information, 101, 1);
}
As you can see, the EventLog source is the same as the EventLog's name. The reason of this can be found in Event Sources @ Windows Dev Center (I bolded the part which refers to source name):
Each log in the Eventlog key contains subkeys called event sources. The event source is the name of the software that logs the event. It is often the name of the application or the name of a subcomponent of the application if the application is large. You can add a maximum of 16,384 event sources to the registry.
To convert a time in one timezone to another timezone in Python, you could use datetime.astimezone():
so, below code is to convert the local time to other time zone.
# Time conversion from local time
import datetime
import pytz
dt_today = datetime.datetime.today() # Local time
dt_India = dt_today.astimezone(pytz.timezone('Asia/Kolkata'))
dt_London = dt_today.astimezone(pytz.timezone('Europe/London'))
India = (dt_India.strftime('%m/%d/%Y %H:%M'))
London = (dt_London.strftime('%m/%d/%Y %H:%M'))
print("Indian standard time: "+India+" IST")
print("British Summer Time: "+London+" BST")
import pytz
for tz in pytz.all_timezones:
print(tz)
Using sqldf package:
library(sqldf)
sqldf("select a.*, b.cnt
from df a,
(select name, type, count(1) as cnt
from df
group by name, type) b
where a.name = b.name and
a.type = b.type")
# name type num cnt
# 1 black chair 4 2
# 2 black chair 5 2
# 3 black sofa 12 1
# 4 red sofa 4 1
# 5 red plate 3 1
Try to use switch case
statement but normally it's not the performance bottleneck.
in case you are interested in reading some data from a .txt
file and only extract few columns of that file into a new .txt
file with a customized header, the following code might be useful:
# input some data from 2 different .txt files:
civit_gps <- read.csv(file="/path2/gpsFile.csv",head=TRUE,sep=",")
civit_cam <- read.csv(file="/path2/cameraFile.txt",head=TRUE,sep=",")
# assign the name for the output file:
seqName <- "seq1_data.txt"
#=========================================================
# Extract data from imported files
#=========================================================
# From Camera:
frame_idx <- civit_cam$X.frame
qx <- civit_cam$q.x.rad.
qy <- civit_cam$q.y.rad.
qz <- civit_cam$q.z.rad.
qw <- civit_cam$q.w
# From GPS:
gpsT <- civit_gps$X.gpsTime.sec.
latitude <- civit_gps$Latitude.deg.
longitude <- civit_gps$Longitude.deg.
altitude <- civit_gps$H.Ell.m.
heading <- civit_gps$Heading.deg.
pitch <- civit_gps$pitch.deg.
roll <- civit_gps$roll.deg.
gpsTime_corr <- civit_gps[frame_idx,1]
#=========================================================
# Export new data into the output txt file
#=========================================================
myData <- data.frame(c(gpsTime_corr),
c(frame_idx),
c(qx),
c(qy),
c(qz),
c(qw))
# Write :
cat("#GPSTime,frameIdx,qx,qy,qz,qw\n", file=seqName)
write.table(myData, file = seqName,row.names=FALSE,col.names=FALSE,append=TRUE,sep = ",")
Of course, you should modify this sample script based on your own application.
