dc443··on Claude Opus 5.5 Intelligence, Performance and Price Analysis (Max)
i assume you mean 6 Luna, because we've had 5.6 luna for ages
dc443··on How Bluesky draws its logo on screenshots
but you didn't read the part where the mechanism is explained? it doesn't do anything like capturing information. it just marks a button "sensitive" causing it to be hidden in a screenshot, thus revealing an icon that was put there underneath the button.
dc443··on GPU Offload in Rust: Portable, Safe, and Fast
I just read this tool up and down but still can't conceive of a use case.
dc443··on Greg K-H: "Writing new code in Rust is a win for all of us"
What i don't get is why people gravitate toward trying to show off how many symbols they're able to manipulate in their brain without screwing something up.

It's a computer. It does what it was instructed to do, all 50 million or so of them. To think you as a puny human have complete and utter mastery over it is pure folly every single time.

As time goes on I become more convinced that the way to make progress in computing and software is not with better languages, sure, those are very much appreciated, since language has a strong impact on how you even think about problems, but it's more about tooling and how we can add abstractions to the software to leverage the computer we already got to alleviate the eye gouging complexity of trying to manage it all by trying to predict how it will behave with our pitiful neuron sacs.

Well he DOES have a threadripper now.
dc443··on Why cryptography is not based on NP-complete problems
slightly off topic but I would like to understand better why there is handwringing going around about cryptosystems being broken by future quantum computers. Don't we already have quantum resistant cryptosystems? Why not just switch to them across the board?
dc443··on I learned Vulkan and wrote a small game engine with it
Thank you. I hope to see progress in these areas when I visit later. I was hoping to be able to go all in on wgpu but if there are still legitimate reasons like this one to build a native app, then so be it.
dc443··on I learned Vulkan and wrote a small game engine with it
Do you know if these things I found offer any hope for being able to continue rendering a scene smoothly while we handle GPU memory management operations on worker threads?

dc443··on I learned Vulkan and wrote a small game engine with it
> WGPU doesn't support multiple threads updating GPU memory without interference, which Vulkan supports.

This is really helpful for me to learn about, this is a key thing I want to be able to get right for having a good experience. I really hope WGPU can find a way to add something for this as an extension.

I wonder how much less ergonomic is is for getting there via Vulkan. For the ray tracing shaders.
dc443··on Raspberry Pi 5
Damn that is pretty impressive. I just drive my 3d printer and run the unifi controller interface with mine. Thanks for the inspiration.
dc443··on x86 is dead, long live x86
I've been hoarding apple devices too. I have a 12 inch macbook, recently brought it up to Ventura. But the blasted thing won't hold a charge. The battery is fine over 90% health but something is causing power drain while it sleeps even when I try to hibernate it.

It's impossible to find a use case for the thing. I might have to sell it.

dc443··on Guide to running Llama 2 locally
I have 2x 3090 do you know if it's feasible to use that 48GB total for running this?
dc443··on State-of-the-art open-source chatbot, Vicuna-13B, just released model weights
Ouch. I got this wrong and was under the impression that GPT4 got this wrong for half an hour, and then figured out after reading it again after returning from a walk that this is one hell of a trick question. My brain automatically assumed that a man's widow is the man's dead wife, but I see that the correct way to interpret this is to realize that it means the man is the one who is dead.

It's pretty awesome to realize that from now onward my computers are going to be able to help catch more and more of the holes that clearly exist in my cognition.

dc443··on Apple Detection of Flashing Lights
There should be an option to control and limit the severity of flashing that is brought about with the flash light for notifications accessibility setting. I like to use it because I don't want to make my phone obnoxiously loud, because i can't hear its vibration, and I still want to get a chance to perceive the notifications, but usually the light is too damn bright and I do worry it could trigger epilepsy in innocent passersby. Having an alternative flashing behavior like a smooth pulsation would be excellent.
dc443··on NP-complete isn't always hard
Could you give some examples of how BDDs are impactful?
dc443··on VALL-E: Microsoft’s new zero-shot text-to-speech model
The commenter you're responding to is talking about Lovelace architecture based GeForce RTX 40x0 products. The Quadro line isn't even released yet on this architecture. You are talking about the specific Quadro RTX 4000 product, which is a TU104 (turing arch, 2 gens behind, with 2560 processors and 8GB memory). The commenter you're responding to is referring to something like a GeForce RTX 4090 which sports an AD102 (lovelace arch, with 16384 processors and 24GB memory).

You were merely an unfortunate casualty of Nvidia's product marketing scheme (and a commenter's slightly imprecise reference to it) here.

dc443··on Some notes on using esbuild
For other readers, it took me a while to figure out that esm.sh is a website you can go to which explains what it is.
dc443··on Goodbye, Clean Code (2020)
The point your parent post was making was that regardless of whether or not you actually got fired doesn't actually matter. The signal you should be paying attention to (which you are surely aware of, since you say this episode still bothers you) is that the environment was a toxic one so if they did fire you they would have been doing you a favor. At least from a silver linings point of view.
dc443··on Economic costs of war
It's hard for me to believe that a modern brick school costs the same as 1.667 miles of concrete pavement, but it does not change the point he makes. It just makes concrete pavement sound really, really expensive.
dc443··on The Google Fitbit Deal: Hazardous to competition, privacy, and our health [pdf]
You took the words out of my mouth. What on earth did I just read? Don't they have video recordings?
dc443··on Show HN: Instantly search 2M recipes
As an avocado fan I have trouble grappling with the concept of guac made without them. Isn't that sorta like orange juice made from things that are not oranges? Feels almost oxymoronic. Good suggestion though.
dc443··on Advice to my young self: forget side projects and focus on your job
It's like a little puzzle snack type of a thing that I've certainly never been lucky enough to need to solve in 15 years of programming yet.

Yes, I think it's really limited in utility. But it can offer some insight into how quick and flexible you are generally speaking.

My first impression is you can do a quick DFS recursive function that does a swap (can prolly use xor operator) on the left & right pointers

dc443··on Planet Ceres is an 'ocean world' with sea water beneath surface, mission finds
Based on the linked (very cool) map, I don’t think what you say is accurate? A flyby of Ceres would be slightly harder than entering Mars orbit, and entering Ceres orbit would be harder than entering Neptune orbit.
dc443··on Roman Finger Counting
And the Babylonians, whose base-60 system's legacy lives on in our timekeeping, used the finger segments on one hand and entire fingers on the 2nd hand to count to 60.
dc443··on Libc++'s Implementation of std::string
I'm not sure that is optimization is relevant now that your CPU's native architecture will be just as efficient with the 8 byte length as the 4 byte one.
dc443··on Reality has a surprising amount of detail (2017)
I find the refrigerator and McDonald's bathroom stall both to be a fairly straightforward metaphysical deduction from the generation of life on this planet and its consequent blossoming of civilization. Both of those things are byproducts that support the functional needs of humans which are the ultimate result of evolutionary dynamics in carbon based life forms found on the planet.

These things which are crazy complex (which you did not pick particularly complex examples of, better examples might be quantum computers or nuclear reactors, but that's ok) are a natural result of the process that evolution kicked off (this is the accident that you refer to) that allowed people to be a thing, which, when they do their thing results in astounding advancements that necessitate complex designs to fulfill their function. I personally don't believe there needs to be a better reason to explain why we have refrigerators, mcdonald's bathroom stalls, quantum computers, and nuclear reactors other than "because we can". That is to say, once humans became capable of inventing those things, it was inevitable that they would proliferate.

dc443··on Reality has a surprising amount of detail (2017)
I have personally stumbled upon this paradigm (value craftsmanship on tools that will have a relevant shelf life), and I credit my ongoing satisfaction with my career to this, at least in part.

Without getting into details and specifics, something I highly enjoy doing, I'm referring to things like Vim, tmux, unix utilities and software, various Linux administration knowledge. Various electronics concepts. I now consciously and deeply evaluate a potential skill to learn based on how likely it is going to improve my life in the long term.

dc443··on Ask HN: CS, still a good career in 3-5 years?
I think you're overthinking it. I totally get where you're coming from, but overwhelmingly what you wrote makes me feel that you've given up on actually enjoying what you do for work. You should place more value on that, if for no other reason than when you enjoy something, it's a positive feedback loop for improving everything: your own mood, your productivity, your self-improvement motivations, and your compensation.
dc443··on Guide to Deep Work
I like what you said but i think grandparent's use of management is not the management that you're referring to.
