You’ve likely at least heard of Marion Stokes, the woman who constantly recorded television for over 30 years. She comes up on reddit and other places every so often as a hero archivist who fought against disinformation and disappearing history. But who was Marion Stokes, and why did she undertake this project? And more importantly, what happened to all of those tapes? Let’s take a look.
Marion the Librarian
Marion was born November 25, 1929 in Germantown, Philadelphia, Pennsylvania. Noted for her left-wing beliefs as a young woman, she became quite politically active, and was even courted by the Communist Party USA to potentially become a leader. Marion was also involved in the civil rights movement.
Get a handle on this bad boy! Okay, so those voids are really more for airing out your palms, I’d imagine, because palm sweat sure is real — you should see the pads of my Kinesis. This kind of looks like two sawed-off machine guns kissing, and I mean that in the best possible and non-violent way.

And yet, pricing (oh yeah, this is gonna be A Thing You Can Buy) will be around $115-155, depending upon whether you want the base kit, or the add-ons, too, minus switches and key caps.
So let’s get into the particulars here. As you can see, there are key wells and thumb clusters, inspired by other keyboards including your bog standard Maltrons, Kinesis Advantages and more modern, open-source takes like the Dactyl. [ntc490] loves the key well-thumb cluster combination, and I do, too (hello from the Glove80). And miraculously, the keys are hot-swappable via sockets.

So please do go visit the thread if this keyboard appeals to you at this price point. I love it, but I would need more rows of keys, personally. The top reddit comment mentions this as well, and [ntc490] says that because the thing is modular, it can easily accommodate more keys in both the wells and the thumb clusters. I seriously want one of these. Just with a few more keys.
The Internet has spoiled us. You assume network packets either show up pretty quickly or they are never going to show up. Even if you are using WiFi in a crowded sports stadium or LTE on the side of a deserted highway, you probably either have no connection or a fairly robust, although perhaps intermittent, network. But it hasn’t always been that way. Radio networks, especially, used to be very hit or miss and, in some cases, still are.
Perhaps the least reliable network today is one connecting things in deep space. That’s why NASA has a keen interest in Delay Tolerant Networking (DTN). Note that this is the name of a protocol, not just a wish for a certain quality in your network. DTN has been around a while, seen real use, and is available for you to use, too.
Think about it. On Earth, a long ping time might be 400 ms, and most of that is in equipment, not physical distance. Add a geostationary orbital relay, and you get 600 ms to 800 ms. The moon? The delay is 1.3 sec. Mars? Somewhere between 3 min and 22 min, depending on how far away it is at the moment. Voyager 1? Nearly a two-day round trip. That’s latency!
Looking for a unique vacation spot? Have at least $10 million USD burning a hole in your pocket? If so, then you’re just the sort of customer the rather suspiciously named “GRU Space” is looking for. They’re currently taking non-refundable $1,000 deposits from individuals looking to stay at their currently non-existent hotel on the lunar surface. They don’t expect you’ll be able to check in until at least the early 2030s, and the $1K doesn’t actually guarantee you’ll be selected as one of the guests who will be required to cough up the final eight-figure ticket price before liftoff, but at least admission into the history books is free with your stay.
This never happened.
The whole idea reminds us of Mars One, which promised to send the first group of colonists to the Red Planet by 2024. They went bankrupt in 2019 after collecting ~$100 deposits from more than 4,000 applicants, and we probably don’t have to tell you that they never actually shot anyone into space. Admittedly, the Moon is a far more attainable goal, and the commercial space industry has made enormous strides in the decade since Mars One started taking applications. But we’re still not holding our breath that GRU Space will be leaving any mints on pillows at one-sixth gravity.
Speaking of something which actually does have a chance of reaching the Moon on time — on Saturday, NASA rolled out the massive Space Launch System (SLS) rocket that will carry a crew of four towards our nearest celestial neighbor during the Artemis II mission. There’s still plenty of prep work to do, including a dress rehearsal that’s set to take place in the next couple of weeks, but we’re getting very close. Artemis II won’t actually land on the Moon, instead performing a lunar flyby, but it will still be the first time we’ve sent humans beyond Low Earth Orbit (LEO) since Apollo 17 in 1972. We can’t wait for some 4K Earthrise video.
My son went over to a friends house this afternoon, when my wife had been planning on helping him with his French homework. This meant she had an hour or so of unexpected free time. Momentarily at a loss, she asked me what she should do, and my reply was “slack off”, meaning do something fun and creative instead of doing housework or whatever. Take a break! She jokingly replied that slacking off wasn’t on her to-do list, so she wouldn’t even know how to start.
But as with every joke, there’s more than a kernel of truth to it. We often get so busy with stuff that we’ve got to do, that we don’t leave enough time to slack, to get bored, or to simply do nothing. And that’s a pity, because do-nothing time is often among the most creative times. It’s when your mind wanders aimlessly that you find inspiration for that upgrade to the z-stage on your laser cutter, or whatever the current back-burner project of the moment is.
You don’t get bored when you’re watching TV, playing video games, or scrolling around the interwebs on your phone, and it’s all too easy to fall into these traps. To get well and truly bored requires discipline these days, so maybe putting “slack” into your to-do list isn’t a bad idea after all. My wife was right! And that’s why I volunteered to take my son to parkour on Sundays – it’s and hour of guaranteed, 100% uninterruptible boredom. How do you make sure you get your weekly dose of slack?

Join Hackaday Editors Elliot Williams and Tom Nardi as they swap their favorite hacks and stories from the week. In this episode, they’ll start off by marveling over the evolution of the “smart knob” and other open hardware input devices, then discuss a futuristic propulsion technology you can demo in your own kitchen sink, and a cheap handheld game system that get’s a new lease on life thanks to the latest version of the ESP32 microcontroller.
From there they’ll cover spinning CRTs, creating custom GUIs on Android, and yet another thing you can build of out that old Ender 3 collecting dust in the basement. The episode wraps up with a discussion about putting Valve’s Steam Deck to work and a look at the history-making medical evacuation of the International Space Station.

An important aspect in software engineering is the ability to distinguish between premature, unnecessary, and necessary optimizations. A strong case can be made that the initial design benefits massively from optimizations that prevent well-known issues later on, while unnecessary optimizations are those simply do not make any significant difference either way. Meanwhile ‘premature’ optimizations are harder to define, with Knuth’s often quoted-out-of-context statement about these being ‘the root of all evil’ causing significant confusion.
We can find Donald Knuth’s full quote deep in the 1974 articleStructured Programming with go to Statements, which at the time was a contentious optimization topic. On page 268, along with the cited quote, we see that it’s a reference to making presumed optimizations without understanding their effect, and without a clear picture of which parts of the program really take up most processing time. Definitely sound advice.
And unlike back in the 1970s we have today many easy ways to analyze application performance and to quantize bottlenecks. This makes it rather inexcusable to spend more time today vilifying the goto statement than to optimize one’s code with simple techniques like zero-copy and binary message formats.
