Chroot into Raspberry Pi ARMv7 Image with Qemu
# raspbian stretch lite on ubuntu

### You can write the raspbian image onto the sd card,
# boot the pi so it expands the fs, then plug back to your laptop/desktop
# and chroot to it with my script 
# https://gist.github.com/htruong/7df502fb60268eeee5bca21ef3e436eb
# sudo ./chroot-to-pi.sh /dev/sdb
# I found it to be much less of a pain in the ass and more reliable
# than doing the kpartx thing

Cómo trabajar con git branches

Workflow con git

Para este proyecto seguiremos la metodología de tener una branch principal master (equivalente a release en otros proyectos), una branch dev (o development) para comprobar que todo funcione antes de enviar los cambios a master y múltiples "feature branches" para que cada colaborador pueda enacrgarse de una tarea definida, trabajarla y probarla a gusto antes de reunir los cambios en dev. Para más detalle y ejemplos pueden usar de esta lectura la sección Feature Branch Workflow.

fork() is evil; vfork() is goodness; afork() would be better; clone() is stupid

I recently happened upon a very interesting implementation of popen() (different API, same idea) called popen-noshell using clone(2), and so I opened an issue requesting use of vfork(2) or posix_spawn() for portability. It turns out that on Linux there's an important advantage to using clone(2). I think I should capture the things I wrote there in a better place. A gist, a blog, whatever.

This is not a paper. I assume reader familiarity with fork() in particular and Unix in general, though, of course, I link to relevant wiki pages, so if the unfamiliar reader is willing to go down the rabbit hole, they should be able to come ou

Edit and review github wiki on your local machine
First, clone your github wiki to your local machine
  1. Checkout your repository wiki via git.
     - You can find the URL at the lower-right of your wiki page (look for the label "Clone this wiki locally")
  2. Now that you have pulled down a local copy of your github repo wiki, create a new file in the repo called _Sidebar.md  - Note that other names might not work.
  3. Within the newly created _Sidebar.md file, you can add appropriate [[link]] markdown syntax.
  4. Add your new file to the local repository, and push via git push origin master.

With the same procedure, you can add a header(_Header.md) and footer(_Footer.md) file.

Stuff I wish I'd known sooner about service workers

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.
