aylons commented on Classical statues were not painted horribly   worksinprogress.co/issue/... · Posted by u/bensouthwood

I will die on this hill, because I'm right. Painters put on the first layer in saturated colors like this, then add detail, highlight and shadow. The base layer stuck to the statues, and the rest was washed away.

This whole thing just won't go away because many people are operating outside their area of expertise on this subject.

Painters layer paint, starting with a saturated base color. These archaeologists are simply looking at the paint that was left in the crevices.

The archaeologists know that and say as much in TFA:

"The paints used in the reconstructions are chemically similar to the trace pigments found on parts of the surface of the originals. However, those pigments formed the underlayer of a finished work to which they bear a very conjectural relationship. Imagine a modern historian trying to reconstruct the Mona Lisa on the basis of a few residual pigments here and there on a largely featureless canvas.

How confident could we be that the result accurately reproduces the original?

This point is not actually disputed by supporters of the reconstructions. For example, Cecilie Brøns, who leads a project on ancient polychromy at the Ny Carlsberg Glyptotek in Copenhagen, praises the reconstructions but notes that ‘reconstructions can be difficult to explain to the public – that these are not exact copies, that we can never know exactly how they looked’."

I'm just happy that both VHDL and ADA are in the list.

Haha. Yeah I feel they’re exact opposites. Emacs is so DIY/wanting to control your experience and create the perfect tool for you.

I feel like ascii art loses something when it's not sized to a standard text mode (at least to width, like 132x132 is fine). At some point you're just using weird pixels and this is approaching that for me. Same goes for changing the color of the characters continuously; terminal colors are cool. I'm probably just a crazy purist
aylons · 6 months ago
It's not even just that: the shadows go mid-character, instead of using characters as pixels. It is just not ASCII ART at all, just some ASCII characters used as a filler.

Eno? Up until recently, that was the only way to generate virtual cards. It's a useful feature for retailers that are too small for me to trust their security. I guess I'll need to start using their website now that it is an option.

aylons commented on PCBs, copper pours, ground planes, and you   lcamtuf.substack.com/p/pc... · Posted by u/surprisetalk
iancmceachern · a year ago
The reason is that the copper is already there, it gets etched away. So it actually costs more to not have copper than to have it.
aylons · a year ago
Yes, but this costs pales in the cost of redoing in case of problems with side-etching and the overall tightened manufacturing constraints.

And yes, they get to recover the copper, at the very least to make treatment easier for discarding (copper is a very bad pollutant). But not only there's a cost, this is dealt with by waste treatment companies that will at most use the copper value to recoup some of the cost of the treatment.

> Other than increased miniaturization, the most striking change is the use of copper pours [...] Why did we start doing this?

We've been doing something a lot like this for as long as I can remember.

Back in the 1990s if there were any big unused copper areas on your PCB you'd mask them to save on etching acid - a gallon of acid would have a lifetime measured in square inches of copper removed, and the less copper you removed, the longer your acid would last.

Meanwhile, a lot of DIY etching processes were very basic. Sure, you could get translucent acid and a transparent bath and heat it to a controlled temperature and run bubbles through it and so on. But if you were on a budget, some room temperature ferric chloride in an old ice cream container would get the job done. And getting the etch resist onto the board? You could draw it by hand with special pens, use transfers, there were special printer toner transfer papers, or you could DIY UV photoresist using printable projector transparencies and the sun as your UV source.

This was not a super-scientific, tightly controlled process.

If you had narrow traces and narrow gaps on one part of your PCB, and large areas of copper to remove on another? Well, if you left it in the acid long enough to remove that large area, could be the narrow traces get etched away too.

So masking off any large areas meant all the copper getting etched was about the same width - thus compensating for the poorly controlled etching process.

Of course, these days professional PCB manufacturing is orders of magnitude cheaper than it used to be. When you send your design to pcbway or jlcpcb they have much tighter control over the process, so you no longer have to worry about this stuff.

aylons · a year ago
Well, you may not have to worry, but if you have large unpoured areas on a design with a professional PCB manufacturer (of the traditional, high-touch kind), they will ask if you want to pour some copper there. Reason being that it makes the process faster, more consistent and reduce possible side-etching on lanes. It may not a make a difference in most cases, but you may just save some time and effort by doing this.

Oh good. In the context of soldering "popcorning" typically means explosive steam formation that puffs up the package a part, often an expensive part because bigger / more complicated packaging is a risk factor. I was having trouble making that fit with the rest of the post.

I went through the same thing, it was a really unfortunate choice of words in the context.
aylons commented on Ethernet History Deepdive – Why Do We Have Different Frame Types?   lostintransit.se/2024/08/... · Posted by u/un_ess

Ironically, this version of the header published in 1980 is what we still use to this day.

IMHO Ethernet is one of the of great examples of backwards compatibility in the computing world. Even the wireless standards present frames to the upper layers like they're Ethernet. It's also a counterexample to the bureaucracy of standards bodies --- the standard that actually became widely used was the one that got released first. The other example that comes to mind is OSI vs DoD(TCP/IP).

Sounds like a cautionary tale: whatever gets released first will stick. If you make a blunder, generations will have to live with it (like IPv4).
