Farewell Mr.Nash. Games and complexity. p vs np

Today, 24 of may 2015,  John Nash passed away in a traffic accident. His wife also passed away in the same accident....

Apart from his work on Game Theory (which I studied a bit back in university), he also had great implications in cryptography and problem complexity.

Here are a couple of good videos about P vs NP. The first one pretty approachable to everyone. Second one is a class from MIT 6.006 by Eric Demaine.





Here's a great talk by Eric Demain I just stumbled upon. This guy is really impressive, follow him everywhere. A true inspiring guy. He's teaching 'Introduction to Algorithms' and 'Advanced Algorithms and Data Structures'

[ANN] - Helm-dash 1.2.1 released

It's been a long time since any announcement on helm-dash. Now that we hit 100stars, we are happy to release a new version which supports third party docsets.

Kapeli keeps a list of user contributed docsets which aren't officially supported but in a contrib repo.

As the way to fetch the docsets changes completely from the official ones, I created a kind of adapter that fetches the docsets info and offers a curated version through a very simple API. The app that manages this is called dashes-to-dashes .  Every 20something minutes it updates the list of user contributed docsets, and makes it available for any helm-dash user who runs `m-x helm-dash-install-user-docset'.  The official ones are still available on 'm-x helm-dash-install-docset'.

There are some improvements in the support for windows, and a few bugfixes here and there.

Also, there's a branch waiting to land that will improve the userdoc trimming. When searching "rails | controller" it'll narrow the search just to 'ruby on rails' docset.

Stay tunned, and thanks for the support!

feh image viewer

My need for viewing images is really low. Just a few screenshots and funny pics, but I need some app to view them.

I usually use emacs for this task, but there's this little suckless app, feh , which is doing its job quite well. I use it to set the background image on my laptop

exec feh --bg-scale ~/dotfiles/wallpapers/sun.png

and I just configured it to accept vim-ish keybindings.
