Considering Rust ...for Video

This is a follow up on my last post. After playing with Rust for the first time last Saturday (thanks Casey), I did a whole bundle of reading about it the next day, Sunday. I also got some tips from Kieran O’Leary on some work that had been done in the open source media space with Rust and that sent me into a spiral and flooded my RC syllabus with links. I had originally intended...

Considering Rust

I am now in an informal Iron Blogging challenge with Janice and Marianne in my Recurse Center batch, so I must talk about technical things and personal things and opinionated things, and NOT BE AFRAID!! This is a blog post ramping up to something more technical and more opinionated. Last Saturday, I paired with Casey, who helped me build something in Rust, a language that I’ve admired from afar (and wow, I saw a talk...

First week at Recurse Center

Okay. How do I talk about this? As many people who know me (many more than who actively read this blog), the Spring 2 batch started at Recurse Center, and I am in that batch! So I am in for 12 weeks (with a one-week break in the middle) of intense learning and programming. Anyway, I summarize all of that best in my syllabus here. I think the best way to articulate my feelings so...

Lenticular film, lenticular codec

Today I explored Reto Kromer’s Lenticular codec (original code written by Joakim Reuteler in 2012, adapted and added to AMIA Open Source in 2017-2018) because it is available, it is open, I know the author (always helps), it is written in C, and I know about lenticular film. Quick crash course in lenticular film: It was a film processing format used around the early 1930s to produce simple color film (tints things green and red)....

All the stuff between EBML and Matroska

Update with more information at the bottom of this post and also immediately below this sentence! Moritz Bunkus, the creator of MKVToolNix, also mentioned to me on twitter that “MKVToolNix v22’s info tool now contains a hex view that even highlights different parts (EBML ID, length field…).” This is much more useful than the general-purpose text editor I used for exploration. Sometimes investigating the GUI instead of just the CLI tools is fruitful! I was...

Making a Matroska Magic Hat

Hello! This blog post is going to scratch an itch I’ve had for a long time and really don’t know what prevented me from doing this when it first occurred to me years ago because it’s very simple. The itch is storing a Matroska file inside a Matroska file. This will go into the steps I took to make the file and what you might be able to do with it later. You will need...

Wild Wild Country and the Magnetic Media Crisis

Wild Wild Country is a six-part documentary series from Netflix about the Rajneesh Movement and especially their attempt to build a utopian city in rural Oregon in the 1980s. To tell this story, the documentary relies very heavily on archival regional television footage and “home movie” footage. And, as countless people have noted, mostly look terrible. This is largely just the state of the tapes (your home movies also probably look terrible), but I did...

Ethics and Archiving the Web

A couple of months ago, I got an email asking me if I’d be on a panel at an upcoming conference held at the New Museum, “Ethics and Archiving the Web.” What an honor! And this past weekend, the conference took place. I’ve been feeling a little bit burned out by conferences over the past year or so, primarily because I felt tired of like-minded people telling each other what they should be doing, while...

Aspect ratios in Errol Morris's Wormwood

Thanks to Peter Oleksik for sending me this “tip” last week: “The aspect ratios in Wormwood are BANANAS” I was curious and have some free time, as I was spared from family events this holiday season and don’t want to leave my apartment because it’s freezing outside, so I took a look. They are, indeed, BANANAS. For context into aspect ratios, you might want to read or re-read the duo blog posts Peter and I...

Introducing: Audiovisual Preservation Training

Hello! I think a proper introduction is in order. Audiovisual Preservation Training ✨ First, a backstory. I was homeschooled. Well, at least that’s what I tell people, because it’s easier to say things in three words than it is in three sentences. Actually, I spent high school doing correspondence courses via a combination of physical mail and the internet. I don’t know which was the cause and which was the result, but I’m pretty driven...

2017 Reflection and 2018 Goals

Welcome to the Ashley Blewer annual report. Here is last year’s. 2017 2017 was not good. We all know it was not good. I spent a lot of time getting hurt and staying hurt. I spent a lot of time supporting those hurting near me (even if not physically near me). I’ve experienced a lot of heartbreak from institutions and the people within them and have had to distance myself from a lot of people...

No Time To Wait! 2

Kieran O’Leary of Irish Film Archive did a perfect job summarizing the conference here, so I really recommend reading that one and only reading mine if you want a sub-par sequel. Or don’t even listen to either of us, just go watch the talks! Here you can find the schedule. Some of the major themes this year: Open source funding models So many of the talks went into the struggles of open source funding, from...

ffmprovisr gets a redesign

Introduction If you haven’t been to ffmprovisr in a while but check it out right now, you’ll notice it recently got a makeover (go check, we’ll wait)! ffmprovisr has been looking the same since its initial inception over three years ago, as I recently noticed while looking through old images. The most noticeable difference, at first, is going to be some of the visual changes, but ffmprovisr actually got a full, comprehensive redesign in terms...

CSS Grid and New Order

Hi! 👋 I gave my website a makeover. I gave it many makeovers! Here’s how that went for me last Sunday, bored and unwilling to do actually-productive and meaningful things. This is what I did and a love letter to CSS Grid Layout. Before First, here is what I was starting with, my previous website. Fine, minimal, Josephin Sans and Open Sans courtesy of Google Fonts, with skeleton for a CSS framework, normalize.css on top...
