For context, David Kriesel gave the infamous talk called “BahnMining” at 36C3 highlighting this. IIUC it’s only available in German: https://youtu.be/0rb9CfOvojk

Sadly, this isn't really right. Humanity settled on solar time. For somewhat obvious reasons.

Alas, I don't see my preferred method of changing the clock by 10 minutes every month taking hold. Basically ever. :D

I also don't think this is nearly as important for places that are not further away from the equator. If you are on the equator, you are almost certainly fine with no change throughout the year.

That method wont work, that is a too large change that happens to seldom. What you want is a leap second every hour for five months to switch between standard and daylight savings time and back, with a month of constant time around each solstice. That gives you a smooth transition without perceptible discontinuities.

> add more channels

and unfortunately increase latency even more with registered DIMMs. Comparing bandwidth increase (50 GB/s) to the stagnated latency (~80..120 ns total, less than ~0.1 GB/s) over last decades, I'm wondering, whether one still can call today's RAM random memory (though sure it can be accessed randomly). Similar to hard disk drives. Up to 300 MB/s sequentially but only up to less than 1 MB/s 4KB random (read).

Depends how pervasive OC3 would have gotten. A 1080p video stream is only about 7 Mbps today.

You only have to bundle about 110 ISDN channels to transfer that (four E1 or five T1 trunk lines).

Confirm/Cancel (like Yes/No) for dialog buttons has been known to be confusing and detrimental for decades now. The button names should always describe action to be taken, not a response to the text above.

My point is that the operator may be genuinely confused by a poor interaction model. Removing that interaction model entirely is certainly an option, but it's not clear that comparing "no dialog" vs "bad dialog" is a strong argument for "dialogs bad, better to have none" - you don't have data for the "good dialog" case, which may be better still.

Like the "Cancel subscription" dialog with options "Cancel" and "Cancel"...

There should be two dark modes: a simple dark mode, like most dark themes today, to work in dimmed lighting, and an actual night mode, designed to be legible but not mess with adaptation in total darkness. I don't know the research on this (and I'm sure military and aviation have lots of data here), but intuitively it should use mostly thin red and green lines.

You can radiate the excess energy away on the non-sun facing part. In theory.

There are even commercially available prototypes of that vacuum cooling technology, if you want to perform your own experiments with that concept: https://www.amazon.com/Thermos-Stainless-Ounce-Drink-Bottle/...

This isn't true. Take 9_A = 1001_2. 28_A = 11100_2, which is 5 bits long (3 set). The biggest number in this path is 52_A = 110100_2, which is 6 bits long (3 set). 5 ≯ 6, and 3 ≯ 3: neither of my interpretations of your statement holds.
fhars · 4 months ago
There is another interpretation, reading "bits" as "set bits" and assuming that textual description (especially the operator "of the") has a higher precedence than multiplication, then your initial number is 9 with 2 bits set, and the largest number is 52 with 3 bits set, and 3 < 2 * 3 + 1 = 7.

If you ignore performance and mathematical elegance and safety and just look at how much a language lets you get away with from a productivity standpoint, I think Ruby is a pretty standout winner and nobody else even comes close really...

Very clear APIs and syntax(with the possible exception of blocks which can be weird because they aren't quite functions), and tons of raw metaprogramming powers.

You can argue it sacrifices too much of the other things to deliver on these things, but it's hard to argue against it doing well at what it optimizes for!

Does Base https://github.com/garybernhardt/base still work with current versions?
