Ex-developer and musician. I also do vintage electric piano repair and design and build vacuum tube amplifiers for guitarists. Some of the time I'm an exec at a consulting firm.

If you want to get hold of me, reply to one of my comments and we'll figure out how to connect.

I thought that too but they're surprisingly fast. I tracked a dot across the Atlantic (US East Coast to UK) and it took around 4-5 days, which is about right.

There's a very nice effect where if you zoom in, time slows.

This is nice, I enjoyed it. Was a couple points off the optimal score for day 8 but when I clicked "Show optimal" I couldn't then go back to see mine to compare. Either way, stretched the brain a bit.

Only nit: fix the walls. They take up one and a half spaces so are confusing, and they're sci-fi steel with flashing red lights. Turn them into one-square-only fences. You use fences to enclose horses, not raptor walls from Jurassic Park.

scrumper··on Daft Punk Easter Egg in the BPM Tempo of Harder, Better, Faster, Stronger?
Kinda ish. Healthy resting heartbeat is around 60bpm and comfortable exertion heart rate - like doing an indefinitely sustainable run, the kind of thing we evolved to do to run down prey - around double that. The most broadly popular styles of dance music tend to float around 120bpm. It just feels natural to humans. At a guess, some combination of biomechanics (muscle twitch speed, pendulum effect of limb sizes against their articulating joints), heart beat, what most people can manage in terms of sustained exercise (as mentioned above), and attention span linked to multiples of musical phrases.

Specifically about keeping tempo, human drummers don't really. They will move around a central tempo, slowing in verses and increasing tempo in choruses and as the song progresses. If you're hearing a fixed tempo in a song, it's because it was recorded with a click track in the drummer's ear. Super common these days because popular tastes for recorded music currently skew towards perfection.

It stems from franchise law which exists to give franchisees a modicum of protection from adverse practices by the much stronger party in the relationship.

One of my former clients was a top 10 automaker. I had a digital consultancy so was very close to their ICE division. They were obsessed with owning the screen, mostly so they could charge subscriptions for it. We were doing all sorts of wild pilots, like AI-powered language tutors for people stuck in their commutes. I was happy to take their money, but of course if any sane person wanted an AI powered language tutor they'd just install an app on their phone and use the bluetooth to talk to it.

OEM margins aren't great and their C suites are desperate to unlock any new revenue streams they can. This is inevitable, and it's a shame the nice thing we had is going away. The baller move would be for Apple to go buy an OEM and roll out a vehicle, but that seems to have stalled. It doesn't have to be self driving!

And as a comment on an article written by, and about, a man who works a manual labor job because he can't support himself as a writer despite having published novels.

Most guilty, indeed.

scrumper··on Hello-World iOS App in Assembly
I'm not sure this is entirely fair though I think you're mostly right. The comment you're replying to is right in terms of the value of understanding one or more levels of abstraction below the one you're working in. Conversely you're right in that learning assembler isn't going to do much to help you debug a failing Flutter app. It's just attacking the abstraction stack in detail from the opposite end - equally myopic.

But none the less valuable because of the additional perspective it brings. That's the real point of it, another lens through which to view and understand the mechanics of the application.

Well, most cellphones aren't subjected to the conditions found under three miles of frigid sea water. Epoxy is also really, really expensive.
scrumper··on Ryanair flight landed at Manchester airport with six minutes of fuel left
Okay that's fair.

I had no issue with the contribution itself, the route summary is helpful.

> And they did well enough by citing that the info came from an LLM.

In terms of acknowledging AI contribution, you're damned if you do, damned if you don't. Here it's sidetracked a discussion; but transparency is better than otherwise I suppose. Perhaps it just boils down to taste - and I don't like it.

Anyway, you made me think!

scrumper··on Ryanair flight landed at Manchester airport with six minutes of fuel left
I'm curious why you did that? It's not a very complicated sequence. The whole point of engaging in a discussion here is to think about the issues raised and offer a point of view while incorporating other perspectives into yours. You've spent your money to bypass the whole intent of this site; akin to you being hungry then sending someone else to a restaurant for you so you can later read their review of the food.

EDIT and you of most of the commenters here, with your industry background, are better placed to offer an opinion!

scrumper··on Ryanair flight landed at Manchester airport with six minutes of fuel left
I think the article says that someone saw 220kg written on a log - that's about 6 minutes worth at cruise. So yeah, it's zero basically.
scrumper··on Ryanair flight landed at Manchester airport with six minutes of fuel left
Correct, article says they landed with 220kg which is around 6 minutes of average fuel burn over an entire flight - bit less at cruise, a hell of a lot more at takeoff/climb.

So I don't think 220kg is enough to do a go-around in a 737 (well, a go-around would've been initiated with a bit more than 220kg in the tank - they burned some taxing to the gate - but you get my point.) I've read around 2,300kg for takeoff and climb on a normal flight in a 737-8. A go-around is going to use close to that, it's a full power takeoff but a much shorter climb phase up to whatever procedure is set for the airport and then what ATC tells you.

I just flew 172s but even with those little things we were told, your reserve is never to be used.

These people came very, very close to a disaster. Fortunately they had as much luck left as they did fuel.

scrumper··on Remember: Kurt Vonnegut Was 47
Irrelevant even if true, which it isn’t, so you’re both mean-spirited and wrong. Does this kind of comment soothe some wound?

Your characterization doesn’t make any sense anyway. A nepo baby how? He wasn’t in the construction business, working a cushy job in dad’s company. He sold cars and did PR work while trying to write. His family’s past seems to have conferred him no advantage whatsoever.

scrumper··on The Rise and Fall of the British Detective Novel (2010)
Yeah that's a good example. That genre tends to export well so platforms like Britbox are absolutely full of them.
scrumper··on AI-generated “workslop” is destroying productivity?
I've only seen it do prototypes of CRUD apps, e-commerce storefronts, dashboards - vanilla stuff in other words. Get an end-to-end skeleton up and running fast; it's really good for that.

Never seen it used for anything novel so I can't refute you.

scrumper··on AI-generated “workslop” is destroying productivity?
Yes true, that is a possibility and something that's quite hard to police remotely. It doesn't feel likely, everyone's working kind of the same, booking the same hours and overtime is no different, but I can't rule it out.

It'd mean that hundreds of people would all be goofing off silently. I'd expect at least overtime bookings to decrease and they haven't - even with our strong incentives to not book o/t.

scrumper··on AI-generated “workslop” is destroying productivity?
I was that manager. I dunno about your senior leader but with me it was coming from a healthy place. After a few months of ra-ra from the C suite about how we were now an AI-first company (we're a tech consultancy building one-off stuff for customers) and should be using it in all our customer projects, I asked the question, quite reasonably I thought, "so am I going to offer lower prices to my clients, or am I going to see much higher achieved margins on projects I sell?"

And, crickets. In practice I haven't seen any efficiencies despite my teams using AI in their work. I am not seeing delivery coming in under estimates, work costs what it always cost, we're not doing more stuff or better stuff, and my margins are the same. The only difference I can see is that I've had to negotiate a crapton of contractual amendments to allow my teams to use AI in their work.

I still think it's only good for demos and getting a prototype up and running which is like 5% of any project. Most technical work in enterprise isn't going from zero to something, it's maintaining something, or extending a big, old thing. AI stinks at that (today). You startup people with clean slates may have a different perspective.

scrumper··on The Rise and Fall of the British Detective Novel (2010)
The classic stories described in the article may have died out in print form, but many of the tropes live on healthily in British TV. There's a vast range of charismatic, rationally insightful detectives to choose from. Granted, a lot of them are police officers which isn't true to the spirit of the article, but many are amateurs. I saw the genre referred to once as "cosy mystery" which pretty much hits it on the head (with, presumably, a candlestick.)
scrumper··on Folks, we have the best π
That was fun, unexpected, learned something. I can barely calculate a restaurant tip but the thing I noticed was that our n=2 circle is smooth and continuous, the others have abrupt angle changes. Perhaps that is a clue to why "our" pi is the smallest.

Oh goody.

scrumper··on Nest 1st gen and 2nd gen thermostats no longer supported from Oct 25
You’ve got to use the one specific brand and type of battery they insist on. It’s some energizer lithium thing I’ll have to check for you and comment later. Anything else fails very fast, the correct ones last for years.
scrumper··on The Size of Adobe Reader Installers Through the Years
I'm generally looking at multi kilopage manuals where rapid search and navigation are important, and good zooming for diagrams. I didn't even try a browser as the machine is a bit constrained and I just thought it'd be too slow. But I'll try...
scrumper··on The Size of Adobe Reader Installers Through the Years
I was pretty shocked by this. I recently bought an old PC laptop to use in my workshop, to run some engine diagnostic software and machine control stuff that doesn't work on Mac. Of course one of the first things it needed was some PDF reading tool so I went for Reader, figuring Adobe's tool would be the least scummy. Installed it and suddenly I was getting McAfee popups? God knows what else it installed along with it. It's horrible. And the shop manual I'm trying to navigate while covered in oil keeps getting obscured by AI popups and ads. F'ing hell.

Maybe I will try this Sumatra thing that the article mentions. I'm coming from Mac where I have Preview built in, and I really don't have the bandwidth to research a goddamned PDF reader. Very disappointed in Adobe.

scrumper··on Perplexity Makes Longshot $34.5B Offer for Chrome
I second this. Perplexity is the only AI I actually pay for. It absolutely excels at the kind of deep search into narrow domains where expertise is concentrated in forums and specialist sites. Things like mechanical work on obscure classic vehicles, vacuum tube electronics, company tax arcana. It's also very very good at those questions you sometimes wake up with, where something happened in the news six months ago and you think, "Whatever came of that?"

Its deep research and Pro modes are great at synthesizing thorough briefings on complex topics too, to get up to speed on a new client or job responsibility for example.

It's not a chatbot for me, it's a brilliant, tireless little research minion.

As always with any LLM you should double-check its final, specific answers. It does occasionally hallucinate when information simply isn't available. Your research minion is just that - a minion, you have to have the context. It's not a teacher or guru.

EDIT: the bottom line is, it came along at exactly the right time for me. Google's search results are pages of ads, and DuckDuckGo insists on showing page after page of content-farm blogspam for the types of topics I search for. It cuts right through all that crap for me.

scrumper··on Trying to play an isomorphic piano (2022) [video]
I watched this, it's a fun video. Turns out an isomorphic piano is one where the gap between every key of the same type (white and black on a regular piano, but here "raised" and "lower", or "fat" and "skinny" or pick your own names) is a tone. There's a skinny raised key between every lower fat key. Chords are always the same shape in every key, but I'm not convinced that's much of an advantage. It looks hard to play, but the video host makes a good go of it.
scrumper··on No Hello
I've seen this a lot from Indian colleagues, some European colleagues, and people from various (not all) Latin American countries too both senior and subordinate to me. I see it occasionally from some older gen X and boomer USA and UK-born people without any obvious correlation to race or gender. In other words it's pretty broad, probably has some cultural aspect to it, but I can't map it to anything obvious.

I don't think it's a failed attempt at politeness actually, partly but not only because it's so obvious how to be courteous ("Hi! Hope you had a great weekend, when you get a sec could you tell me XYZ?" or "Hey - hope your day going well. I'm stuck on ABC and it's quite urgent, please get in touch asap.") and it's even more obviously discourteous. I think it's more that we don't have the same understanding of the medium. Slack/Teams/Chat to me is a lot more like text messaging than email, and it's not at all like walking over to someone's desk or phoning them. Their mental model of it probably differs. (They're wrong of course.)

Most charitable explanation is, they want a realtime chat and don't want to be pushy about it.

scrumper··on I let Claude Code write an entire book
I've seen worse at an airport bookshop. This was funny:

"The irony is delicious and deeply instructive. Every flaw we've identified in artificial intelligence exists, magnified and unchecked, in human intelligence. But here's the critical difference: when it appears in AI, we can see it, measure it, and try to fix it. When it appears in humans, we call it "just being human" and move on."

Poor Claude thinks it's all a bit unfair.

I didn't read much of it though, it made me feel a bit like I was a naughty avout being punished by reading pages from The Book.

scrumper··on Stone Soup AI (2024)
I first read this story in the back of the manual for a DOS program called Fractint in the very early '90s. It was a super-fast fractal generator made by a collective called the Stone Soup Group. It's still around but the SSG disappeared years ago.

The story stuck with me, I told it to my kids only a few weeks ago.

scrumper··on Launch HN: Maritime Fusion (YC W25) – Fusion Reactors for Ships
"First-wall power flux" - am I right in thinking that means the heat energy the innermost wall has to contain? Half a megawatt per square meter? Good lord. You're not making it out of 3/4" plywood then.

Maintenance isn't just about downtime though right? This is gonna have to be supported by your crews traveling globally with trade secret, exotic parts. Not even on the top ten hardest things about this of course.

It's an exciting bet for sure, so good luck - if it works, you're taking a big bite out of a really nasty carbon source.
