Using the OpusFile library with Microsoft Visual Studio for Windows

The "opus" codec performs pretty well across a wide range of bit rates. When doing voice chat over the internet, or streaming music, or even including compressed music for a soundtrack for a game or other application, it is a pretty reasonable choice. Especially since it's free, as in beer!

What is this I don't even? Android Google sign-in hell.

I recently changed the password for my two non-work Google accounts. As part of that, my Android smartphone (a Samsung Galaxy II with Android 4.3) got signed out of all of its Google services, and started asking me to log in.

DFRobot Nova Basic Kit -- Test Report

The kind folks at DFRobot sent me a sample of their "Nova Basic Kit" to test out.

A reference for those milling ABS plastic enclosures

I had a hard time finding good feed and speed numbers for milling holes in plastic ABS enclosures ("project boxes.")
After a number of failed attempts, where the plastic would just melt and burr and become a mess, I found something that works for me, at least on the Desktop ShopBot at my local TechShop:

Making things

I make things. At work, I make software -- and, being super busy, I don't have much time to blog about all the cool stuff we do to grow IMVU.
During my "copious" spare time, I do things that aren't software. Like hardware.

What loading a home page should not look like

I like watching Anime. Netflix has a lot of good things, many of which come from the American importer/distributor Funimation. But Funimation has started not making everything they have available to Netflix; instead they have a subscription service specifically for their own site. This service is about as expensive as a Netflix streaming subscription (I think one dollar cheaper?) I'm afraid this is the future of streaming video, unless someone can come up with a $30/month all-high-quality-programming streaming video service. But I digress.

Lead Game Tester: 60 dollars a year?

I recently saw this ad:

A whole 60 dollars a year? That's cheaper than outsourcing to Congo! (the poorest nation on Earth).

Job recruiting scam pro-tip: Proofread your ads!

A very large number

Here's a number. Anyone care to guess what it is?

Range queries in key/value stores, part two

In my previous blog entry, I talked about cross-shard transactional integrity for key/value stores, and how SQL databases have solved this problem. I also poked fun at some of the best known key/value stores for not quite solving all of my problems for me, for free. Go read it, it's fun times!

Cross-shard transactional integrity

I've been looking at NoSQL data stores for online transaction processing lately. Yes, related to work :-)

The basic model of a key/value store, where the value is a JSON object or similar, only gets you so far. The bonus with it is that it is very, very easy to horizontally partition ("shard" or "federate"). The draw-back is that you really can't do any online queries on anything other than primary key values. If you're trying to do a query on, say, "any foobar created between 2011-01-05 and 211-01-06" then you're screwed -- you have to traverse the entire data store to find that.
