ffmpeg has come a long way since the pre-1.0 days. With its elaborate system of routing filter outputs, its ability to capture video from video cards, and support for GPU-based encoding, it has become quite the powerhouse in the video world.
This article outlines how we built ffmpeg to capture video from a Blackmagic Design DeckLink mini and encode it using Intel’s QuickSync technology (h264_qsv).

I recently discovered that my Galaxy S7 Edge was reporting its display resolution as 640dpi, when I expected it to be approximately 534dpi. What’s the big deal, you ask? Well, it’s causing dynamically sized elements on screen to be approximately 17% bigger than they were intended to be drawn. Some users might like this, as it will make elements just a little easier to tap on. But others might not like it, because you can’t display as much information on the screen.

We’ve enjoyed using our Amazon Echo for the past few months. Its built-in features provide some useful and fun capabilities, but the availability of the Alexa Skills Kit promises to really help the device maximize its potential. ASK allows third-party developers to build “skills” to add all-new features to Echo. Naturally, I couldn’t help but take a stab at building an Alexa Skill myself.

Recently, some changes at work have me doing more WordPress work than I’ve ever done before. I am mainly helping a group within our division deploy the sites they are building for clients. After doing a few of these, I’m just stunned by how difficult it is to move a site from one domain to another.
Given how common it must be for WordPress developers to develop a site on one hostname, e.g. “dev.MYCLIENT.com” or “MYCLIENT.ourdevenvironment.com”, before moving it to its final destination, it’s really hard to believe how hard WordPress makes this.

I recently needed to compile Titanium Mobile SDK from scratch. I was a little intimidated by the process. And as I feared, I ran into some nasty issues.

a fairly large-scale (100+ JS modules, 40K lines of JS) app with Titanium Mobile SDK

A couple of times, I’ve found it necessary to know what version of google play services I’m dealing with. For example, when I was using a number of Titanium modules that were dependent on google play services, I had version conflicts. But Google Play Services versioning is a nightmare. This article tries to make sense of it all.

Note: this series of articles applies to CentOS 7; for CentOS 6, see this series.
CentOS (and of course, it’s upstream distro, Red Hat Enterprise Linux) has an
extremely powerful, but somewhat poorly documented, tool for rapidly deploying machines
and managing their configuration: kickstart. Kickstart lets you build a custom
installation that can run hands-free. So not only is the installation quick and easy
for you, you can be confident that your machines are configured exactly the way you
want them to be.

I was very excited to see that the OpenELEC team had released version 4.0, based on
XBMC Gotham. I read a lot before attempting an upgrade, and I still had huge problems
with the upgrade from OpenELEC 3.2.
