*thousands, not thousandths, right?

The correct number is fourty six thousand, two hundred and fifty five square mm.

ash_091··on The hidden engineering of runways
I don’t think anything you said is wrong, but I do think you’re misreading the intent of the channel.

Practical Engineering is very deliberately framed as edutainment. The animations, pacing, and level of depth are conscious choices meant to keep non-specialists engaged rather than to maximize technical rigor.

In that sense, it belongs alongside other popular "science-y" channels like Kurzgesagt, Vsauce, and Technology Connections: content that prioritizes narrative and engagement over completeness or instruction.

The target audience is the broad middle of the technical bell curve. Animations of runway layers may make the video less appealing to you, but more accessible to a much larger, less technical audience.

Different goals imply different success criteria. If the goal is reach rather than comprehensive education, a million views in seven days looks like success.

ash_091··on Ask HN: ADHD – How do you manage the constant stream of thoughts and ideas?
+1, Todoist has changed things for me drastically.

I was diagnosed with ADHD a year and a half ago in my ~mid 30s. The meds (Vyvanse) help somewhat, but the real key to improvement for me has been using Todoist.

IME the real trick is using it consistently, and for everything. My routines (e.g. morning routine: meds, eat, coffee, brush teeth, brush the dog's teeth, etc etc) are all in Todoist, not because I struggle to focus on getting that stuff done in the morning (well, sometimes, perhaps) but because starting the day with do-easy-thing, mark-it-done, repeat, sets up the rest of the day to be run by Todoist instead of the bit of my brain that goes "I know we should be getting ready to leave but WHAT IF YOU WROTE AN APP TO DO THIS COOL THING, JUST QUICKLY TRY THAT NOW, YOU CAN LEAVE AFTER".

I had a similar experience with org-mode too. It was great at work where I'm at my desk all day, and made a huge difference, but not having a good mobile experience makes it impractical for day-to-day home use.

ash_091··on TurboDiffusion: 100–200× Acceleration for Video Diffusion Models
So with 108,000 (60 X 1,800) Bob Ross PPUs (parallel painting units) we should be able to achieve a stable 60FPS!
ash_091··on I sell onions on the Internet (2019)
How about a site which parses your credit card / bank statement to find out where you're spending money and provides tips to save cash based on that spending (which could be sourced from community submissions + voting)

E.g. I buy supermarket gift cards from a slightly obscure site which sells them at a 5% discount. Super easy way to save a few hundred dollars a year. The hardest thing was discovering that this was an option.

ash_091··on I cracked a $200 software protection with xcopy
> I'm not understanding why TFA author has such an attitude about this

To me it reads like an ego trip rather than any kind of righteous vendetta against the author. Implicit in "look at the dumb thing this other person did" is "I'm smarter than them because I noticed the dumb thing".

ash_091··on C100 Developer Terminal
While I agree with your general sentiment, the 10 key being on the "wrong" side could be good, perhaps, in some cases?

Historically I've done some heavy spreadsheet work where the resting position of my hands which minimizes movement is right hand on the mouse, left hand on the 10 keys. On a normal keyboard that has the disadvantage of causing a "closed" posture which isn't entirely comfortable.

Outside of that kind of niche use case though, it definitely feels like a strange choice for developers.

ash_091··on Roblox is a problem but it's a symptom of something worse
NFC tags in custom "avatars" unique to and customizable by each kid, turning friends into collectables? I would've been all over that in my early teens.
ash_091··on Git 3.0 Defaults to "main" Branch Instead of "master
In the spirit of genuine curiosity, who is making you feel like less of a person wrt the choice of main/master, and how are they doing that?

It sounds like you're saying that git maintainers are intending for you to feel like less of a person because you don't agree with their choice, but I don't understand how you arrived at that conclusion.

ash_091··on Virgin and Qantas to ban use of portable power banks after string of fires
A train can go from "cruising speed" to letting passengers off to escape a fire in about a minute.

A plane might take anywhere from five minutes to several hours to be able to safely let passengers out.

Personally I feel that's a good enough reason to impose more robust restrictions on Things Which May Cause Fire on planes compared to trains. Especially in the case of lithium batteries where they're more or less impossible to extinguish one they're going.

ash_091··on Nearly all UK drivers say headlights are too bright
> most people in my life react negatively if I express emotion that what they are doing is upsetting

Right. I guess they feel accused, as though you're attacking their behaviour rather than sharing how it makes you feel, and instinctively become defensive in response?

It's wonderful to meet people who don't think this way. My partner is incredible at this, I can tell her "when you X I feel Y" and know without a doubt her reaction will come from a place of trying to work together to understand whether the problem and solution exist in X, Y or both.

ash_091··on Nearly all UK drivers say headlights are too bright
The recommended 3 second gap is a much bigger distance than most people recognise, especially at high speed.

On another note- I feel sad that you could tell your mate "the way you're driving is making me uncomfortable" and be met with basically "your discomfort isn't valid because [technology] so I won't change my behaviour".

MIG is for hobbyists. Real programmers use TIG.
ash_091··on What happened to Apple's legendary attention to detail?
Is this generally true for laptops / phones?

I've often wondered why I can tell by touch whether a device is charging or not from the slight "vibration" sensation I get when gently touching the case.

ash_091··on How I bypassed Amazon's Kindle web DRM
> we just didn't care. Upper management seemed happy enough

This is very relatable. Management want X, engineers recognise X is dumb and deliver something that sorta looks like X, management see something that looks like X and are happy.

ash_091··on Getting syntax highlighting wrong
Are we sure this guy isn't trolling us? The advice about theming while using a yellow-on-black blog format, the "dark mode" toggle which makes the whole page black except for a spotlight focused on the mouse cursor... I'm not sure.
ash_091··on Getting syntax highlighting wrong
> Close your eyes (not yet! Finish this sentence first) and try to remember what color your color theme uses for class names? Can you? If the answer for both questions is “no”, then your color theme is not functional.

I'm sure this varies person-to-person, but for me at least this is not a good test.

I couldn't list the notes in Clair De Lun, but I'd certainly notice if I heard the wrong note played. In much the same way, I have no idea what color classes are in my theme, but I certainly notice when it's wrong.

Agreed, I had to check a couple of other pages on his site to make sure it wasn't ironically done for just that particular post.

ash_091··on Sea Rise Simulator (2023)
It's a "paperclips" situation.

Someone vibe coded this with the prompt "write a webapp which shows the effects of rising sea level as accurately as possible". The AI decided that the way to determine the outcome as accurately as possible was to simply cause the rising sea level and observe the result.

ash_091··on The AI coding trap
The "thinking & coding" vs "thinking & fixing" graph is interesting. I've found this to be the case recently as I've been trying out Codex. I expected to spend a lot of time fixing the AI's code. Weirdly that has led to me spending a long time fixing issues which turn out to be nothing to do with the code.

Most recently I was struggling to get an authentication setup working. I spent at least an hour combing through the code looking for the mistake. The issue turned out to be that the VM I was working on had a broken ipv6 configuration.

ash_091··on Why do some gamers invert their controls?
I said "pivot point", as in the center of rotation. All rotations have a pivot point.

ash_091··on Why do some gamers invert their controls?
Yes. I clarified that "you" meant something different from the usual meaning in the comment you're replying to.

Are you making a joke? I feel like I'm being whooshed.

ash_091··on Why do some gamers invert their controls?
GP is talking about third person perspective games. "You" (the character you're playing) aren't the camera. You are the character the camera points to.

The camera is hovering somewhere above/behind the player character. To move the field of view left while keeping the player centered in the FOV, the camera has to translate/orbit right.

ash_091··on Why do some gamers invert their controls?
IIRC Halo had a neat system for setting inversion like this.

Instead of asking the player "do you want inversion or not", it instructed the player "look up" and observed their input.

ash_091··on Why do some gamers invert their controls?
If the lever is on your side of the pivot point, you'd have to invert both horizontal and vertical axes. I don't have any data, but I certainly don't know anyone who plays with both axes inverted (in first person games).
ash_091··on Ultrasonic Chef's Knife
> Or that can cut through bread easily without a serrated edge?

Yes. Absolutely. IME a quality sharpened chefs' knife is far better at cutting bread cleanly than a serrated knife, which by contrast will leave a rough edge and loads of crumbs.

I spent a solid ten minutes researching this and couldn't find any suggestion that there's any problem with the title.

Could you explain how it's ungrammatical?
