Published the next article in my series on embedded development.
Interrupts and Timers. The previous post ended with a dilemma: how can we toggle the LED every second and read input from the serial port? One of the ways we can do this is with a timer interrupt. To introduce the topic, we'll first take a quick tour before diving into the subject in more detail ...

Only got about a half hour on the telescope tonight, but I did get two images out. The first is a rather heavily processed (most astro images are) composite of Jupiter and Ganymede, and the second is notable ad the first shot of Venus through the scope. There was heavy cloud cover, and these had to be timed to breaks in the cover (many frames were lost due to the clouds); it was also not quite dark yet. Still, decently happy with how they turned out. The Jupiter image was really useful for learning that workflow.

A half of hour of observing and several hours of processing...

Astrobin links: http://www.astrobin.com/186253/ and http://www.astrobin.com/186251/. These links have more technical info about the shots if you're into that sort of thing.

I use Lynkeos and Pixinsight because I've got Linux and OS X, though I've been thinking of grabbing a windows machine for this.

It's alive! Powered by Ada, though the code is a little hacky.

In a fit of insomnia, I started hacking on a #golang client for https://keybase.io/. Right now, it can be used to look up users on the site, download their public keys, upload an armoured OpenPGP key file (i.e. not from the keyring), and delete keys from the account. Tomorrow, I should be getting OpenPGP keyrings hooked in, which will allow me to add support for signing things. Then I have to bug the Keybase team to figure out how to use my client for verifying oneself on the site.

Started a series on embedded programming for people who know some C already.
Introduction to embedded programming. Some friends have become interested in doing some embedded or bare-metal programming. I've started writing some articles on the subject to help them get started. There's a Bitbucket repository for these tutorials as well. Getting started (added 2015-06-19) ...

The drive train mostly works (still needs a few tweaks to get timing down just right). Now to get some sensors hooked up.

Last night, I finally got a chance to do some astrophotography. I've had the telescope for a while but only recently got an SLR and adapter for it. They aren't very good, but these are the first four pictures to come out of that.

It was rather impromptu. The nights here have been so overcast (among every other reason I dislike the Bay area, you can add the low number of clear nights) that I'd given up hope. I chanced to look out about 22:00, saw a star, and quickly got the scope set up without acclimating. It was amazing to see Saturn in opposition, though there wasn't a whole lot else to see given the light pollution here.

Spaced on the fact that I need to get plane tickets (and a hotel) for GopherCon. I was living in Denver when we started planning, but now that I'm in California, guess I should get on that. Not sure I'll make it out there what with my living situation now.

This will be most effective if people actually call and email their congress people.
Reddit, Mozilla, Tumblr, Imgur, and over 6,000 other websites are protesting NSA surveillance. Join them.
