print out ascii tables in python using data in the form: [ ('column 0 title', 'column 1 title' ..), ('row 0, column 0 data', 'row 0, column 1 data' ...) ...]
# I needed to print out ascii tables from data in the form:
# [ ('column 0 title', 'column 1 title' ..),
# ('row 0, column 0 data', 'row 0, column 1 data' ...) ...]
#
# and surprisingly it got complicated because of variable lengths of the data.
# I googled for 'standard' ways of doing this and I found suggestions like:

Low-value pull requests are worse than useless

Why do I feel insulted Re: automated bots making pull requests

An open source project is a lot of work. There are features to be built, bugs to be solved, releases to be made, documentation to be written and the inevitable support you have to provide via GitHub issues, Twitter and mailing lists.

Like anything worth doing, throughout this process there are hard problems that need to be solved. Valued contributors are ones who study the project's philosophy, understand the subject matter and are thinkers who gift their experience and time to the cause.

Therefore a person or a bot who joins in with a pull request that was a result of running a tool against the project's source code—like code linting or stripping of unnecessary whitespace—is a lowest form of contribution there is. It makes the statement: “Here, I didn't bother to see what current problems are in need of discussing/solving, so I ran a widely available script from the command-line t

Getting rock 0.9.9 to make 32-bit binaries with MSYS2 on Windows

It seems the command-line toolchain of choice changes every fortnight on Windows (except if you're in the MSVC camp, but that's a no-go for ooc at the time of this writing).

The new kid on the block is msys2, which I first had doubts about, but it turns out it's a great way to get a shell, install the packages you need via pacman (!) and get started with ooc on windows.

Debugging with jdb in scala

#Debugging Scala with JDB

It seems impossible to find answers on how to debug Scala with jdb on Google. I wanted to consolidate what I've learned in a easy to digest guide. Please feel free to comment with other tips I may have missed, or corrections to what's here.

##Classes Setting a breakpoint in a class is just like debugging java stop at my.package.ClassName:22

Fix Ubuntu and other Linux slow/hanging file copying via USB.

If your running a x64 bit Ubuntu or other Linux and find USB transfers hang at the end apply this fix:

echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes

I suggest you edit your /etc/rc.local file to make this change persistant across reboots.

sudo nano /etc/rc.local
