ajford··on Pricing Changes for GitHub Actions
Sure, but that shouldn't be a time-dependent charge. If my build takes an hour to build on GH's hardware, sure thing, charge me for that time. But if my build takes an hour to build on _my_ hardware, then why am I paying GH for that hour?

I get being charged per-run, to recoup the infra cost, but what about my total runtime on my machine impacts what GH needs to spend to trigger my build?

Inclusivity and democratic governance of a project is a strike to you? Seems like perhaps your hat is showing...
ajford··on Aphantasia and Psychedelics
Interesting. I'm somewhere on the aphantasia spectrum, but I very rarely have vivid dreams. Most dreams I would describe it almost like remembering an audiobook instead of a movie.

But I do occasionally have a vivid dream, and though I can't be certain I could swear that I remember more vivid dreams as a child/early adolescent. But by the time I was entering college I rarely remember my dreams and the ones I do remember are like those I described above with little visualization.

It's really interesting to hear about how others perceive these sensory experiences.

ajford··on Aphantasia and Psychedelics
I interpreted it as more of "concepts" and not the word floating in space. That's closer to how I would describe my experience. With effort I can kinda force a static visualization but for lack of a better explanation it feels almost like a wireframe pre-render. Sounds similar to how you describe it.

Dreaming feel reminiscent to what an Audiobook feels like when thinking about the dream after waking up.

ajford··on Electromechanical reshaping offers safer eye surgery
LASIK is well known to only be a short to mid-term solution. The eyes age like the rest of you, and any correction will eventually be outpaced by the natural weakening of your ocular muscles to the point where you can no longer pull focus and require glasses. Further correction is possible, but from what I remember being told by my doctor and my own reading, the bounce-back from the surgery is rougher as you age.

I know a few folks from college who got it done and a bit over decade later they're going strong. My own surgery is just about hitting a decade (couple of months shy). That said, I have a family friend who had bladed LASIK done in their 50s (late 2000s) and their outcome was bad with total loss of sight in the affected eye. The result on their other eye was barely an improvement but plenty of scarring lead to halos and starbursts.

ajford··on Electromechanical reshaping offers safer eye surgery
I elected for LASIK as my near-sighted prescription was severe enough that I could only see about 6-8 inches in front of my eyes without my glasses.

Also, I could only get my prescription filled in high-index lenses as the normal lenses would be too thick for nearly any glasses shop to order and grind. And had been that way for at least a decade by the time I opted for LASIK.

Poor control of my eye reflexes meant that even after over a year of trying I still couldn't reliably wear contacts, and was a highly stressful part of my day when I managed to get them on.

I had a family friend that went for LASIK very early on (late 2000s iirc) and had a horrible outcome losing sight in one eye, and a couple of friends in college that had amazing outcomes, so I had seen both sides. Ultimately, the LASIK operation was a very quick and pleasant operation for me, and the results were beyond my expectations. Nearly a decade later, my eyesight is still fine though I think I'm starting to see some blurring at middle distances that wasn't there a couple years ago. Did get some strong starbursts at night for a couple of years but I've either gotten used to them or they've faded.

After wearing glasses for around 20 years of my life, I love the freedom of no longer wearing them.

ajford··on Feasibility study of a mission to Sedna - Nuclear propulsion and solar sailing
I always figured it was from Nuclear pearl-clutching and genuine fear about launch disasters. Especially after the various Apollo and shuttle disasters.

Though with how SpaceX has been blowing up rockets left and right, probably a good idea to not have nuclear materials launching until that's been resolved entirely.

Boca Chica beach is a mess now, I can only imagine what new Fallout installment we'd get if South Texas became irradiated from a failed launch.

ajford··on Cloudflare to introduce pay-per-crawl for AI bots
> As someone who has actually built working micro payments systems

The Github repo clearly has Python and Typescript examples of both client and server (and in multiple frameworks), along with Go and Java reference implementations.

Maybe check the whole repo before calling something vaporware?

ajford··on Elon Musk's DOGE Posts Classified Data on Its New Website
Yep. They claim all sorts of things, but there is no transparency or proof that any wastage or actual fraud was present.

It's all just ideological things that Project 2025/MAGA/Daddy Musk doesn't like. The CFPB is a perfect example. Musk wants to get into finance so he's gutting a department that only exists to protect consumers.

ajford··on Anyone can push updates to the doge.gov website
It's a damn shame the IRS funding is getting gutted and those billionaire 1% will be getting cuts anyways. Hard to go after those not paying when Daddy Trump and Daddy Musk cut the legs out from under the enforcement and audit folks.
ajford··on Nokia 5110 – Back from the Dead (2022)
Haven't used the M8, but I just set up an AGM M9 on Mint Mobile two days ago.

That said, that's kinda cheating since Mint is a T-Mobile MVNO and I haven't tried it outside my usual T-Mobile service area.

ajford··on Murderbot, she wrote
One of my favorite series in the last few years. The tech side of things are believable enough (at least compared to the usual handwavy nature of sci-fi books) and now I understand why, as it seems Wells has a history in IT!

I'm struggling to not gush about this book and trying to avoid spoilers, but if you like a good sci-fi action/adventure book with a strong lean towards a journey of self discover it's really worth a read.

ajford··on Exploring the Cost and Feasibility of Battery-Electric Ships
It seems like the profit-driven attitude put us in the ecological situation and maybe it's time to put the environmental impact first.

It also doesn't help that the bid/contract process is skewed to select the lowest bidder.

You can always forget to add some margin here or there, or fail to plan for problems that might pop up. It's easy to game the system because sunk costs make it nearly impossible to switch once you've started.

ajford··on Air traffic failure caused by two locations 3600nm apart sharing 3-letter code
And how many would assume that the incorrect unit abbreviation would mean something else? If I said Kbps and KBps, it's an entirely different unit of measure. NM and nm are VASTLY different, and unless you are already familiar with measurements in Aviation and know it's Nautical Miles, your first instinct is gonna be to read it as the unit it's supposed to be.

The article title is talking about location data and computers, I've seen many people forget floating point precision when comparing and getting bit by tiny differences at the 10^-9 or smaller. That seems just as obvious on the outset as non-unique location designations in what the average person would assume to be a dataset that's intentionally unique and unambiguous.

ajford··on Air traffic failure caused by two locations 3600nm apart sharing 3-letter code
I too first read it as nanometers. Perhaps it's just those with engineering/science backgrounds who have far more experience with nanometers than nautical miles?

I've never had cause to see the abbreviated form of nautical miles, but I know nanometers. Also, given purely the title I could see it being some kind of data collision due to precision errors between to locations that should be the same airport but perhaps two different sensors.

ajford··on Boeing Revokes Health Benefits for Striking Workers
Recently unionized at my workplace and the most vocal anti-union folks were high-level/long term employees that went "Well I have mine, I can negotiate my own wins", while saying they weren't willing to pay dues just because some folks couldn't negotiate on their own.

Ignoring that half the reason they can ask for whatever they want is that they are the last standing expert on some esoteric internal thing. Of course you get treated well! Too bad the rest of us don't have 15+ yrs here and practically own this or that piece code.

ajford··on A $1k Wheelchair
The question was would you spend that on a device you spend 8+hrs in each day, which is something people often ignore.

This is a device you _live_ in. This is someone's mobility and independence you're talking about. Not a "I spend 30 minutes to an hour a day riding", or a "I commute to work on this" but instead "I use this to enjoy life".

ajford··on Linux Horror Stories and Protection Spells (Volume I) (2021)
Well that's reductive and dismissive. These are perfectly understandable mistakes or scenarios one might find themselves and a simple method to avoid/rectify them.

Find is a very powerful and useful tool, and the author gave a clear example of when and where it might be useful. They also called out how to prevent accidents with `rm`.

ajford··on Why GitHub won
I taught my research group Git version control in college. It was part of a "new student/researcher onboarding" series that we put all the new grad students and undergrads through. But we were in Radio Astronomy, so there was a lot of data processing and modeling stuff that required being comfortable within a remote ssh session and the basics of Linux/bash/python. I know it was already being used in Radio Astronomy (at least in the sub-field of Pulsar Astronomy) at the time and was part of the reason I didn't get pushback when I proposed making sure our group was trained up on using it.

We switched to Git as a whole in early 2009 since it was already a better experience than SVN at the time. Could be off by a year or two, given how long ago this was and the fact that I was working with the group through the end of high school in 2007-2008.

We only added GitHub to our training later in 2011-2013 era, but we ran our own bare git repos on our department servers until then. And students/groups were responsible for setting up their own repos for their research projects (with assistance/guidance to ensure security on the server).

Last job also made use of our own internal bare repos, admittedly mirrors of our private GH projects, and our stack pulled from that mirror to ensure we always had an instance that was not dependent on an external vendor.

Current role also makes use of bare git repos for similar reasons.

I think the knowledge is there and plenty people do it, it's just not news/blog worthy anymore. It's not new or groundbreaking so it gets little attention.

ajford··on An open-source flow battery kit
Why wouldn't you take a scratch-build EV on the road? People build kit-cars all the time, and an EV has a much simpler control system.

This is a very simplified project to prove the concept and provide a test bed for further exploration, not an end-product by any stretch. This seems like the perfect project to test various membranes and electrolyte solutions.

ajford··on Please do not attempt to simplify this code
Given that the engineering safety folks are more than likely not the ones writing the code, I doubt it.
ajford··on New ways to catch gravitational waves
The university I studied at had a Gravitational Wave center under the Physics dept, and all the professors would joke about how LISA had been "less than a decade away" for 20 years.
ajford··on Google no longer developing Material Web Components
It's serving as both a demo of their generative AI and is an entertainment pre-show. It's not meant to be a presentation or deeply informative.

And how is that any different than any other piece of jewelry? It in no way impedes or impacts your life, just like hair color or cut, earrings, other necklaces, even wedding rings.

Why does it matter that it has a significance beyond "it's pretty"? As long as it's not obviously discriminatory in nature (like a necklace full of swastikas), then why does it have to pass your "decency" tests?

ajford··on NASA releases Hubble image taken in new pointing mode
Used to do radio astronomy before switching to software, and we would joke that you could fund all of US science grants for a decade by driving to the local airforce base and stealing couple of jets and their loadouts. It wasn't that far off from accurate, sadly.
ajford··on DJI ban passes the House and moves on to the Senate
I love the intention of the law, but it's so... flexible... in implementation that shitty implementers ended up making the browsing experience horrible with intrusive pop-ups and geo blocking.

On mobile every page load ends up with me spending the first minute or so on page dealing with the half-screen "don't sell my info" cookie dance, followed with the ad-block pop-ups.

ajford··on I sold TinyPilot, my first successful business
There's an entire section titled `Why Sell`.

> I missed writing code....

and

> My wife and I also wanted to start a family. TinyPilot only occupied about 20% of my time, but it occupied 90% of my stress. I would have done a terrible job juggling founder stress with new parent stress.

Changes in life circumstances changed his priorities. It wouldn't be the first or last person I've heard of that wanted to go back to coding after ending up in mgmt/founding something.

ajford··on How bad are satellite megaconstellations for astronomy?
Because telecoms keep pocketing the money instead of actually building out broadband. https://www.huffpost.com/entry/the-book-of-broken-promis_b_5...
ajford··on How bad are satellite megaconstellations for astronomy?
Ok, who funds it? National Science Foundation doesn't allocate nearly enough money as it is, let alone enough to replace the tens to hundreds of active telescopes producing scientific data every night. And those telescopes are already oversubscribed with people waiting in line for available time. So unless we're slowing astronomy to a halt, we'd need similar numbers of telescopes.

And none of that takes into account that many of these telescopes are used specifically as experimenter telescopes where a given scientist can use their own equipment to perform unique observations that cannot be easily done with space-based telescopes.

It took over a decade to produce the Webb telescope and get it into space, and still is a massive feat of engineering not easily reproduced. We're not nearly to a point where we can just write off ground-based observatories in place of space-based ones.
