Most of my "favorited" comments on here are by software people with confident yet incorrect statements (usually by way of vastly underestimating complexity) about one of my domains of expertise. I can't find it but one of the

In addition to the other comments, in general o-rings are actually very difficult to use for vacuum sealing. Unintuitively, at least until you have some experience in seal design, lower pressure differentials are much harder to seal than la

I don't think this looks bad but I think this will look dated very fast. The exterior looks like a continuation of the last 20 years of car designs in general, not an update to Ferrari design. An exception is the rear-end which is a go

The flipper zero was already in a grey area because it easily enables one to do things in licensed bands and do things you’re not allowed to do in unlicensed bands. They can’t plausibly add even more functions in this area and still sell to

I'll give you another one: In Japanese there is the (unserious) term "enbug" which is the opposite of debug.

Tokyo is relatively dense but it's nothing like what you expect from movies or from visiting there for a few days. The majority of people live in buildings 3 storeys or less (above 3 storeys there are a lot more requirements). There&#x

If you are on the near side of the moon[1], you will always see Earth see around Earth as it rotates and as the moon orbits it. You will also see it in different phases, like how we see lunar phases from Earth. If you are on the far side of

At my workplace someone always orders the what they perceive to be the "best" cables. They aren't thunderbolt, they are just oversized with thick braiding. They are all so stiff and heavy you can barely handle a phone while c

Personally, I like Apple's iWork. Keynote is slightly less fiddly than Powerpoint. I like that in Numbers you can have multiple movable tables on one screen without constraining column widths etc to each other. I also like that Pages i

15 years ago I had a 7GB mobile data plan (in Japan). After 7GB, it was throttled to 100kbps. If I tethered my PC and there was an update available, or browsed modern sites (especially while tethered), this could easily be wiped out in a fe

If I had to guess, with so many devices (speakers, microphone, webcam) on top of any external ones you connect, having multiple inputs especially one that can't possibly connect your computer to those devices, is virtually guaranteeing

The historical reason why is that UK homes were wired early in history for lighting with a ring circuit going throughout the house, and this was also literally set in stone so impractical to phase out for a long time. So the regulations had

Making different rules depending on the class of e-bikes make sense vs just pretending all e-bikes are "bikes" and allowed everywhere bikes are, even though at some point they are more akin to motorcycles. In Europe this is mostly

I had a new one yesterday. In Apple Music (iPhone), you can long hold on a song or album and press "add to playlist" and then select the playlist. The next action you probably want to do is long hold on another album and tap &quot

>Screens are getting bigger and bigger, yet they make things smaller and harder to click on. And despite things being smaller, there's also white space everywhere so there is less information on your screen. The trend in UIs is maki

These projects are cool but to me they seem like they all come from the place: a programmer opens up a CAD program, and within days concludes that they would prefer if they could use their existing scripting skills to make something instead

I use ABS as a baseline, it holds up well, is easier to sand than most other materials, and is soluble in acetone which gives you some nice methods for smoothing layer lines as well as adhering parts together. It requires a heated chamber t

It becomes pretty weak even on a hot day in the sun and in a hot car can melt (not into a puddle but into al dente pasta).

"It just works" has become true for the top brands of consumer 3d printers in general. They are not simple devices (and neither is a 2D printer), but I don't think they are more complex than they need to be. It's just th

Those voltage standards are kind of meant for very local things. If you really get into industrial things, one should look to industrial standards that work over longer distances. That is things like RS422, RS485, and increasingly industria

The remaster from a few years ago is great. It has minor graphical improvements such that it looks how you remember it.

The rain thing is true anywhere I've driven. Even worse, when there are old white lines grinded away for some change, and new white lines added 0.5 lanes away. In certain wet conditions the old lines become equally or more "white&

It varies a lot in the US. Major highway in Florida? Very visible lines. Minor highway in Colorado with all the paint and reflectors scraped off by snowplows, even if the road is in good condition? Not as visible. Rural somewhere? Good luck

I live close to you and I agree it's bad. But trust me, it's way worse in North America (where I also drive annually or so).

Might be some mistaken confirmation bias there. Canadian registered vehicles are required to have "daytime running lights" while American cars are not. You might be seeing low beams vs no beams, as opposed to high beams vs low bea

by johnwalkr 11mo ago
High also refers to the lack of beam cut-off or masking[1], not only the intensity. In UK English, the terms are "full beam" and "dipped beam" to reflect this. [1] For older US cars, it was more about intensity as the ma

On a previous HN (I think) discussion about stickers, one person scanned the lid of their old laptop, printed the whole thing as a sticker, applied it to their new laptop and then continued to put more stickers on top of that.

The whole MacBook lid fades from UV over time, and underneath any stickers will be darker.
