Interesting SSL Issue

Shortly after I upgraded to OS X 10.9.2, I was connecting to, and I got an SSL error. At the time, I didn't think anything of it (after all, sites have bad SSL certificates all the time). However, I noticed it again today when looking at the page for Reaper of Souls, and decided to look into it again. When I did, I found something very unusual: my system has a second copy of the DigiCert root CA certificate in the "login" keychain. For those of you who aren't familiar, OS X uses a hierarchy of …

Pebble Steel First Impressions

I've had an article sitting in Draft status since June 2013 about the Pebble smartwatch which I bought during their Kickstarter campaign. The article essentially said that the Pebble has awesome features, but feels like a toy and scuffs if you look at it askance. I was planning on going into detail about how apps like httpebble and smartwatch+ feel immensely hackish.

Well, as of today, I'm confident reporting that Pebble has resolved all of these issues with the Pebble Steel and Pebble OS 2.0.

Pebble Steel on table

I'm going to talk (briefly!) about both of these new releases. All of the …

A Rant on Redis

It's been a while since I posted, and I've been spending a lot of time fighting with Redis, one of the darling databases of the NoSQL era, at work, so I thought I'd grace y'all with a brief rant on Redis, what it's good at, what it's bad at, and so on.

What is Redis?

Redis is an open-source moderately-structured in-memory key-value store. This means that, unlike full relational databases, it doesn't have a fixed schema, and it can't perform server-side operations like joining and filtering data1, and theoretically it's faster. Redis looks an awful lot like memcache, but …

GPG (2013 Update)

In light of all of the hullabaloo about PRISM and other spying technology, I thought it'd be good to remind all of your dear readers that we've had the technology to ensure private communications on the Internet for 22 years in the form of Pretty Good Privacy (and the much-more-commonly-used implementation, GnuPG). Ars Technica had an okay article about e-mail encryption with PGP which I recommend reading, although you should keep in mind that most security professionals would consider infrastructural PKI like SSL and S/MIME to be compromised by nation-state-level adversaries (and all associated MIC contractors).

Anyhow, my GPG …

My Storage Problem

Storage is cheap, or so we're told. Amazon will sell me storage for $0.055/GB/month in “the cloud”; 3.5" hard drives are hovering around $0.06/GB. However, my laptop has a little 250GB SATA drive that is (a) slow and (b) getting full. So I desire to replace it with a fast little SSD. But that raises the question of what to do with my stuff. I'm asking you, Internet. Details below the fold.

60,000 scrobbles

I used to post these on Facebook as Notes, but since the Timeline refactor, I frankly have no idea how to use Notes; so I guess I'll just post on my own blog. I use (me) to track my music-listening habits (and sometimes for other things). As of some time recently, I've passed 60,000 scrobbled plays since 2006. Yay!


Here's a graph I made (click for ps version; gnuplot continues to be the best thing ever):


Cheers, all.
