>PTX's instructions are analogous to writing assembly for CPUs

How else would you have understood it? At this level it's literally just pedantics. In the same way you can say C doesn't technically compile to assembly for CPUs. The point is that it's the lower abstraction level that is still (more or less) human readable. But just like in CUDA, you may want to write parts of your code in it if you want to benefit from things that the higher level language doesn't expose. The terminology might seem different, but in practice it is pretty analogous.

I believe CDC Cyber series of mainframes were installed in many countries. I knew of at least two, one in the institute that i studied in and another at a bank, both in Calcutta (aka Kolkata), India in late-80's/early-90's.

My first job was implementing a Personnel Information System using Cobol85 on a Cyber 180/840A in the above-mentioned institute. Its OS was named NOS/VE and it had its own system programming language named Cybil. There were racks of manuals which unfortunately i didn't understand much of since i was a noob fresh out of school. A lot of hardware and OS research/advances were first done in the mainframe world before being scaled down and adapted to smaller computers. I wish there were some special courses teaching how hardware/OS/Languages evolved from the beginning so that we can see concretely how a single idea started from simple origins and ended up as the highly complex implementations we have today. History gives you insight which you can never get by reading just the facts today.
We had one of these, at my first job. I wasn’t allowed to use it. I wrote most of my stuff in WordStar.

Come to think of it, I’m not sure I ever saw anyone actually spending a lot of time, writing anything. Most of us were allowed to play with it, but we weren’t really allowed to sit at it, and write docs.
Would love to know more about the tech stack and the idea behind the site. How it started, and why...
It can take quite a bit of engineering just to get the same source to produce the same results in many C or C++ toolchains. "Reproducible builds" require work; all sorts of trivial things like the length of pathnames can perturb the results. Not to mention having to have the same optimizer flags.

"Do these two binaries always behave the same for the same inputs" is practically an unsolvable problem in general. You can get fairly close with something like AFL (American fuzzy lop, a fuzzer and also a type of rabbit).

yes, it's really plug-and-play. and the standard to which every feature was held from the start inspires confidence in its future; as opposed to alacritty with its "just use another terminal then, we're not considering this", and wezterm, whose kitty keyboard protocol implementation had more bugs than not (can't hold it against them - the protocol is nice but the document called its "spec" is just ghastly). They're still great, of course.

Show HN: Prepare for exams with your own set of questions
What does this app do?

If you are preparing for exams and have a whole set of questions, you can organize your questions as per a simple structure, load them into the app and start revising.

Why this app?

I recently started preparing for AWS certifications. For revising the topics I used AI and AWS documentation to generate a huge set of questions. But then I didn't find any tool/app into which I could load these questions easily. Even the one that I found was a little complicated and not serving my purpose (sorry I forgot that app's name). So I quickly put together this app using plotly dash.

What was my requirement based on which this app is designed?

I wanted a simple interface where the app

1. shows the question with choices
2. I make a choice
3. The app shows the correct answer
4. Along with the correct answer, explanation and reference url are provided.

That's it. Simple process to memorize and master some topics.

I'm going to be using this extensively to prepare for my exams. I also plan to publish my question sets once my preparation is complete for each certificate. Hope someone finds this useful.

Initially I had plans to have score, analytics and such. But then I didn't want to spend too much time on this app. Maybe in future I will add those as well when I'm relatively free.

When the frequency of AC divided by the speed of light gets close to the length of your wire (ie. around 1Ghz), the regular rules of electricity no longer apply.

In the high frequency rules, you should consider that the energy you're sending down a wire is instead transmitted in the insulator - ie. it is effectively a radio wave guided by the conductors on either side.

If one of your conductors is not a wire but a ground plane, then the radio wave will travel in the insulator between the other wire and the closest bit of ground plane. Further away bits of ground plane, the signal gets effectively cancelled out because all the alternate paths the signal could take all have different path lengths and therefore phase shifts.

It's not that that future's unimaginable. It's more that it would be nice to have an easy path to knowing how these tools will be funded. They will suck time and effort out of the ecosystem of Python tools, which is fine, except it's not fine if they vanish or decay in X years' time because of funding issues.

I don't know the solution, and I really think these tools look about as great as tools can look, so I'm very keen to use them. I would just like some way to know that they'll be supported for 10 years at least.

Kitty on Mac has a few visual issues that Ghostty doesn't have:

- the text rendering looks slightly blurry when comparing side by side (Kitty looks blurry, Wezterm and Ghostty look crisp)

- when resizing the window, the window content 'wobbles' (Ghostty is stable, both Kitty and Wezterm have the resize wobble)

This wobbling effect is a known issue with Metal views (no idea tbh why Apple can't fix that in the window system), the solution is to 'anchor' the view to one window side during resizing (although not perfect, since during the maximize transition the window content doesn't scale), but the basic wobbling fix is fairly simple: https://github.com/floooh/sokol/pull/963

In general I have the impression that Kitty feels quite 'heavy' on macOS compared to both Wezterm and Ghostty (and iTerm2 which I used before feels heavier than all those combined).
it's a good argument

I can answer that from a very pragmatic point of view. I was able to download ghostty and get it to run the way I expected in about 5 minutes. Everything was smooth, intuitive, and the defaults were very good.

I tried many other terminal apps in the past and was always unimpressed, so I kept using Terminal.app. Ghostty is the first terminal emulator in years that worked better than Terminal.app.

That would be exactly the opposite thing to say if you want people to simmer down.
You are thinking in terms of authority instead of as a scientist synthesizing diverse evidence and considering possible biological mechanisms.

They are not vouching for those cited three doctors here, but considering their claims as weak evidence within a broader context.

If you’re going to look just at authority, consider that the authors of that blog are well respected cancer researchers who recently discovered a promising new cancer treatment in active clinical trials. I’m an academic in a related field, have met them personally, and can vouch for the fact that they are innovative out of the box thinkers with a lot of good ideas.

It is important to distinguish between quackery and open minded scientific thinking. This is how the “sausage” of new medical discoveries are made: by creative people thinking “off the rails.”

Again, I am not in any way advocating for high dose iodine to anyone- and I would not do it myself. Only that it can increase thyroid hormone levels through a well understood mechanism, and some people have treated their hypothyroidism this way.
I am legitimately confused at other people around me thinking that this exponentially evolving technological explosion will end at a steady state that will be at all familiar to us.

Well, in this case I think the subject also is corporations v. people, as people can't lobby to Congress to get tax breaks. In this particular issue, the problem is both that corporations aren't taxed enough AND that they can evade the law by getting special dispensations.

I'd be upset the most at:

> Congress might give Tesla even more tax breaks. A bill passed by the House of Representatives in the previous Congress would have retroactively reinstated a provision allowing full expensing of research and development expenses which could save the company up to $2.4 billion in taxes.

> I'd feel a lot more comfortable in the prospects of AI if their big boosters weren't so gung-ho about it replacing absolutely everything. Compilers (and by extension decompilers) are one of the areas where we have the ability to have formal proofs of correctness [1]--and the fact that AI people seem to be willing to throw all of that away in favor of their maybe-correct-but-does-it-really-matter-if-it's-not tools is extremely distressing to me.

God yes. These people are infuriating; it's as if they've abandoned the concept of provable correctness, or never understood it in the first place, and replaced it with "looks good enough to me on a few examples". Some sort of gambler's fallacy where if you get a right answer once it doesn't matter how many wrong answers you get.
I was, too, but I knew it would be a huge pain to track down (the crashes are very random). This is the kind of thing that MacsBug was good for.

You cannot buy a car in Europe without:

- lights permanently on ("safety", definitely not for your ability to get lost in the dark)

- continuously stores logs of speed, brakes, seatbelts, signal, vehicle inclination, GSM connection etc ("safety", called "black box" in Europe, also warns the driver when local speed limit exceeded)

- permanent GSM connection ("safety", definitely not for tracking, pinky promise!)

- continuously monitoring the driver's head/face ("safety", called driver drowsiness warning)

- engine turns off when stationary (the default setting can't be changed by the user, but by a car service with the right tools)

- car brakes on its own ("safety", but it's so bad I turn it off every time I power it on, it brakes when someone nearby but not right in front of you slows down, cannot be disabled permanently)

- signals left/right at least 3 times
I love the first two and especially the last point in the list so much.

AI code could be just assembly with loop unroll, memory alignment, registers and so on optimization. It need not be code a human would generally write but it will be optimal.

I should point out that UTC didn't begin until 1960...

The 28 minutes jump is likely Iceland coming into alignment with GMT, for much the same reasons as Ireland did; to improve trade and commerce in a world now using telegraphs, telephones and trains. We're ok becoming disconnected from mean solar time in order to connect more with each other.

Samoa skipped a day in 2011, jumping from UTC−11:00 to UTC+13:00, so that it could align with Australia and New Zealand, its biggest trading partners -- so Australia's Friday is also Samoa's Friday.

We'll always have discontinuities in civil timekeeping, as it's there to serve the whims of humans, not the other way around.
