After a lot of reading about AWS and the failures that have happened over the years, I’ve come to the conclusion that to be truly resilient against complete AZ failure, you need to have enough capacity running in both AZs to handle the entire load of your application.Continue reading AWS: hedging against AZ failure
Recently, I tried to upgrade my old OpenELEC 3.2.4 system to LibreELEC 8, which ships with Kodi 17. Things did not go well.Continue reading Kodi and RC6 bug on Intel NUC (Celeron 847)
We are in the middle of a massive migration to the AWS cloud. While we are excited by the prospects of ditching a lot of our hardware responsibilities, you can’t make a change this big without some pain.
So far, Snowball has been the biggest source of frustration.Continue reading AWS Adventures, part 1 – Snowball
I’ve used Picasa for over 10 years to manage my family’s photo library. We have about 50,000 images in there with 22,000 tags, stars, album memberships, etc. Now that Picasa will no longer be supported by Google, I had to find a replacement. And it really hasn’t been easy. I thought I’d share my strategy for anybody who might be in a similar situation.Continue reading Migrating away from Picasa 3
We’re in the process of building out some new Linux-based video encoders, and we want to output to a LOT of different destinations: live streams, archived versions on disk, high-quality versions for future editing, JPEG stills, etc.
QuickSync is a great way to get more out of our processors by offloading the encoding to the GPU. To figure out what architecture to invest in, we ran some tests with a Broadwell processor, the Core i7 5775C (3.3 GHz), and a Skylake processor, the Core i7-6700K (4.0 GHz).Continue reading Benchmarking QuickSync on Broadwell and Skylake

With the release of Media Server Studio 2017, Intel provides Linux with the ability to leverage QuickSync on Skylake processors. This is a welcome development, as Skylake’s graphics capabilities are significantly better than previous generations of Core processors.
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).Continue reading Building FFMPEG with support for Decklink Capture and QuickSync encoding (Skylake edition)
NOTE: this document covers Intel’s Media Server Studio 2016. If you want to use Media Server Studio 2017 with a Skylake processor, see this article.
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).Continue reading Building FFMPEG with support for DeckLink capture and h264_qsv encoding
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.Continue reading Galaxy S7 default config not using full display resolution
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.Continue reading Ruuvu: building an Alexa Skill for IMDb ratings with alexa-app
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.Continue reading Why is changing the hostname for a WordPress site so hard?
