1 - Create an empty folder, it will contain the files created in the next steps.
2 - Create a file named project.json with the following content (adjust the port number and rootDirectory as appropriate):

All Swing-related operations happen on a dedicated thread (the EDT - Event Dispatch Thread). If this thread gets blocked, the UI becomes non-responsive.
Therefore, if you want to delay an operation you cannot use Thread.sleep. Use a javax.swing.Timer instead. For example the following Timer will re...
When ASP.NET handles a request, a thread is assigned from the thread pool and a request context is created. The request context contains information about the current request which can be accessed through the static HttpContext.Current property. The request context for the request is then assigned t...
This returns information about a specific classifier ID you have trained. This includes information about its current status (i.e., if it is ready or not).

While the Java Date class has several constructors, you'll notice that most are deprecated. The only acceptable way of creating a Date instance directly is either by using the empty constructor or passing in a long (number of milliseconds since standard base time). Neither are handy unless you're lo...

When assigning, since self retains blockProperty, block should not contain a strong reference to self. Those mutual strong references are called a "retain cycle" and will prevent the...

A query engine is required in order to execute SPARQL queries over a dataset. Query engines may be embedded in applications, or accessed remotely. Remote access may be through a vendor-specific API, or through the SPARQL protocol if an implementation supports it. This documentation will not cover ho...
git diff myfile.txt
Shows the changes between the previous commit of the specified file (myfile.txt) and the locally-modified version that has not yet been staged.
This also works for directories:

git commit -m 'Fix UI bug' --date 2016-07-01
The --date parameter sets the author date.
This date will appear in the standard output of git log, for example.
To force the commit date too:
GIT_COMMITTER_DATE=2016-07-01 git commit -m 'Fix UI bug' --date 2016-07-01
The date parameter accepts t...
pd.read_excel('path_to_file.xls', sheetname='Sheet1')
There are many parsing options for read_excel (similar to the options in read_csv.
pd.read_excel('path_to_file.xls',
sheetname='Sheet1', header=[0, 1, 2],
skiprows=3, index_col=0) # etc.
Output some information about a known remote: origin
git remote show origin
Print just the remote's URL:
git config --get remote.origin.url
With 2.7+, it is also possible to do, which is arguably better than the above one that uses the config command.
git remote get-url origin
In case your project needs to be based on a specific Symfony version, use the optional second argument of the new command:

$ symfony new my_project_name 3.1
# use a specific Symfony version
