AMD has great hardware, but their software is a different story. It’s poorly documented, unstable, and doesn’t deliver good performance for end users.

I’ve been working with the AMD MI300X for a few weeks, trying to get matrix multiplication running with tools like CK, Triton, or hipBLAS. However, the performance is only about 50% of the theoretical peak (FP16: 650 TFLOPS/s vs. 1300 TFLOPS/s in the whitepaper). Note that this is with matrices initialized to zero. When using random floats, performance drops by 20%—this is confirmed in AMD’s documentation.

Meanwhile, the H100, MI300X’s competitor, has a theoretical FP16 performance of 1000 TFLOPS, and I can achieve 800-900 TFLOPS with matrix multiplication using CUTLASS and random floats initialization.

AMD needs to improve their software quickly if they want to catch up with NVIDIA.
No AAA professionals in the entertainment profession have built a gen AI model up through their own vision that I'm aware of. AAA Nerds build the next version to distract away from flaws of the last and hope the api will get heavy use. I wouldn't expect output to be compelling with that attitude. I expect repulsive or parody clips to continue until some great creatives feel like building their replacements properly.
> This seems like hyperbole.

It's not, there are multiple historical examples of societies, including the US, that place a low value on human life.

Heck, you'll even find comments in this thread talking about how important it is to cut funding to the useless eaters... errr undeserving masses.

Current US society isn't that bad, however, there is a significant population of people that see no problems with things like child labor and completely privatizing education (and everything else for that matter).

> I don't think the US treats any children as disposable refuse, no matter how dissatisfied you are with the current system, I'm certain that isn't the intent.

I never said the current US policies treat kids that way. I do, however, see some disturbing rhetoric throughout this thread about how we spend to much time/money/effort on individuals the commenters deem as worthless.

That kind of gets to what I was trying to say, though. The 'just-so' story I hear often is that men in STEM fields are incredibly sexist and this is just how it is and certain policies are the only way to fix it. I'm willing to accept that might be true but I would like to know why.

I don't really buy the "computers were marketed towards men" argument that was mentioned a few child comments down. I also don't really buy into the idea that men are just inherently sexist and women aren't, especially since I've heard both mysogynist and mysandrist comments from women in my workplace...

Why are fields like law, medicine, and mathematics more receptive to women?
Don't confuse Electron with Web.
The word "computer" to describe a person who does computations dates back into the 1600s, and is exactly where we got the current word.

Up to around 1940, the vast majority of the world's computers were people, and there were legions of them across all areas of government and industry.

There were around 250 total automated computers in 1955, around 20,000 in 1965, so I doubt human computers were outnumberd until the 1970s/1980s at best.

Right. Because these things require some thought and analysis if you truly think that you yourself are having issues with screen time or other attention-related issues.

I may or may not have that right now but I for sure did some years ago. And if you are having issues with your attention? Boy, loading on more stuff that you are supposed to “attend to” for sure does not help. Someone who is having self-reported issues with their attention is not going to see some automated mindfulness message and go, oh wait time to slow down and take a good gander at what I want to spend my attention on right now.

On the contrary that will just tire them more. Which makes them more susceptible to losing their awareness or attention.

But people who think there is one-weird-trick to fixing these issues are incapable of understanding the +1 attention problem: that loading more stuff onto the person is not going to help.

Very true. I recently wasted days trying to setup IPSec on OpenWRT with no success. IPSec support is broken into dozens of packages without proper dependency resolution. No GUI support. Sparse documentation, and what little documentation is out there is outdated and mostly consists of sample configs rather than true documentation. You see, OpenWRT likes to break configs from version to version and the docs are never updated. You can't follow documentation from upstream because OpenWRT auto-generates the package's config files from its own configs. Which are sparsely documented.

"Helpful" forum posts mostly suggested to "use Wireguard" with a notion that IPSec is an archaic protocol that is not worth anyone's time to support, and the user is dumber for trying to use it.

Hardly.

> Yes, because it's most people. It's most of your addressable market, whatever you're selling. It's also their siblings and parents and spouses. Some of mine, too. Possibly even yours.

No, this is vastly overstated. Most people in the world never saw the headline of the linked article.

> The problem is that a lot of the news headlines intentionally lie. The pattern is, put a purposefully misleading statement in the headline, then correct it in the article.

The headline in question did not lie. Nor did it mislead. The headline is accurate. Of course there's more to the story, which one can read in the story if one chooses. But this notion of an intentional lie just seems to come from the minds of Tesla apologists and not from any reality outside their minds. I disagree entirely with the notion.

Here's a question: how would you rewrite the headline?

How about "Cybertruck’s Many Safety Defects Make It Worse Than 91 Percent of All 2024 Vehicles"? Would you prefer that?

If the managers are so checked-out that they can't even equitably distribute the work their teams have to do, it's really hard to see how any software no matter how magic could help. Seems like it would just give them excuses to be even more checked-out.
This makes a lot of sense and glad to see it (don't have to rely on ROCm adoption for Apple). Apple is smart to use under-valued hardware. Nvidia with its hold on CUDA have inflated hardware pricing/performance. Nvidia still leads in the largest scale SKUs but Apple's usage on pro/consumer devices is certainly below those needs.

This pattern follows how Apple would switch from PowerPC to Intel, SCSI to IDE, or between Nvidia/AMD for GPUs. It diversifies their supply chain and forces suppliers to compete on performance/price.

How is that keeping Microsoft from accessing your GPS, sensor data, wifi, camera/microphone etc? Sure, they can't get at SMS or your other apps and your work won't have access to your entire device but it means MS can still access your location (using GPS and nearby bluetooth/wifi), record audio/video, read/control sensors (accelerometer, proximity, gravity, temperature, pressure, magnetic field etc), have full network access, etc and can record and collect that data whenever they feel like it for the most part.

I'm amazed when people can remember specific details like that from decades ago. If you asked me to describe the specific leak I was chasing when I learned to use a memory profiler, there's no way I could tell you. It's just something I know now, and I use that knowledge when I need it.

It seems like some people have this sequential narrative of their experience in their head, where events are strictly ordered—but for me it's more like a pool, or an unordered set. I learn things Just In Time, they go in the pool, and eventually they fade away if no longer relevant (goodbye, VB6). That doesn't mean I don't care about the craft, it just means I'm focused on the future rather than the past.
Could be wrong but I don’t think the OpenFit version is for running or biking - it’s mainly for the gym.

I have the OpenRun version and use it for biking and running and it’s great. I’ve been using these a lot running and I prefer these over my Sony noise canceling over ear headphones. There is just something about being outside and still being connected to surroundings - yes for safety but even beyond that - I just run better with my ears open to the air.

I’ve tried several of the bone conducting variety. Shokz is the easiest to use. They also just released a new version that has even better sound called the OpenRun 2 or something similar and it seems to have an even bigger bone conducting audio device.
> if they say "none" and "none", i know what to expect.

Something tells me this is not the case. I expect that you have passed up some very good developers, but it seems like that is not what you are looking for if those are the types of questions you're asking. Most people don't have a "strongest" or "favorite" anything.

The Epic of Gilgamesh references him gloriously restoring ancient cities destroyed by the Flood. Of course, by the time is was written, Sumerian civilisation was already ~2,500-3,000 years old, so it's hard to tell if Sumerians thought those cities were theirs, or someone else's.

No?

It seems like you're just talking about a `Rectangle` in the abstract rather than the real limitation that even `class Rectangle` is subject to the rules of the runtime engine that renders said `Rectangle`...in a component tree...with the restrictions of the OS/GUI framework...

The process should be the reverse of that. Don't collect data unless you have been through the process of checking that it has a legal basis.
I don't really use a lot of script that wraps git; but so far the two things I do use---lazygit and github cli---don't have problems with this approach. Github CLI can identify the correct corresponding repo on Github, and also can choose the right user account associated with this repo if there are more than one authenticated user.

I mean, it seems to me that any script that tries to do something with git remote URL, should deal with any string that git thinks is a valid remote URL. `ssh-host-name:owner/repo` is not exactly an edge case.
Anyone who works closely with diffusion models knows the "world model" thing was hype. Diffusion models are really good at faking, starting with nonsensical large-scale structure and forcing it towards plausibility with lots of nice details.
Show HN: Tools for building AI React apps
Building tools to simplify how to build AI into React apps, called Hydra AI (short for "hydration".)

The idea is to build React components like normal, tell the AI when they should be used, and let the AI decide when to show them and what props to fill them with. The "list of things that are possible" in my app is, in a way, defined by the components that people can interact with, so why not just let AI control those on behalf of (or alongside) the user instead of trying to figure out all new AI logic?

Looking for people to try building something with Hydra!
Yup. IANA dind't have ccTLD retiring procedures yet, when Soviet Union collapsed in 1990. But would they want to, they could delist it at any point. IANA holds the registry for all TLDs and - that's extreme and unlikely - could delist .ru, .ir or .kp at any moment.

I seriously doubt it's ever a deliberate conspiracy in engineering apart from shenanigans like what happened at VW, but it's net effect of product managers, accountants, and contract manufacturers who modify PCBs and BOMs after it's passed off to them to save money on retail products. And so it's likely unintentional with negligence, but it benefits the company. Except for some Samsung appliances made ~ 2010-2014 which seemed to fail just after their warranties expired. I suspect highly-optimized designs for "consumables" like incandescent lightbulbs and parts for cars use data to tweak design life, more often than not, in their favor. And, with the pressures of multinational oligopolies and BlackRock/Vanguard/State Street.. there is little incentive to invest $100M into a moderately-superior incandescent lightbulb using yesterday's technology that lasts 100kh and 5k cycles and sells for $1 more than the next one. Maybe if we (perhaps a science/engineering nonprofit thinktank that spanned the world and gave away designs and manufacturing expertise) had quasi-communism for R&D, we could have very nice things.

It's not my fault if other people are too dumb to comprehend TCO because I would buy the $25 bulb if it had a 30 year warranty.

Chebyshev polynomials have as roots nth roots of unity, so of course these are going to show up. It's one way to define them.

https://en.wikipedia.org/wiki/Chebyshev_nodes

The nth roots of unity are incredibly well studied, and some of that stemmed in the 1700-1800s on trying to factor things. The entire field of analytic numbers theory has taken these ideas to incredible (think decades of study and research to be state of the art) depths.

As others have said, the plug-in system for Hugo is weaker than Jekyll. I think preprocessing is a viable alternative. I built something that generates markdown (especially the preambles) from a sqlite database. As a separate step, Hugo generates the web pages.

My code is messy, and probably not suitable for others, but it's here: https://github.com/ralexander-phi/rss-blogroll-network/blob/...

This uses a weekly web crawler run to populate the sqlite database (https://github.com/ralexander-phi/feed2pages-action/tree/mai...) and it generates a couple thousand pages which are then hosted on GitHub Pages (https://alexsci.com/rss-blogroll-network/).

My objection to strong types in python is philosophical. Python mimics natural language, and natural language rejects strong types for context resolved ambiguity.

In the way we resolve these issues in natural language, we can resolve bugs in python, that is, “do you mean integer ’3’ or string’3’” instead of insisting we define everything always forever.

To me, people who use type hinting are just letting me know they have written code that doesn’t check in line.

Totally believable if the debugging device was doing something with a serial port. I once hacked something together to interface a PC serial port to a Raspberry Pi. The PC serial is real-ish RS-232, with negative voltages. The Pi side was just 0/3.3V positive. I had a nice 18-volt power brick laying around, and just split it's output down the middle--what was 0 volt ground was used as -9 volts, the middle voltage was now 0 volt ground, and the 18-v line was now +9 V.

At first everything seemed OK. but when I plugged a monitor into the PI I Was Made To Realize a) the nice 18-volt PS really was high quality, and although it was transformer-isolated its output ground was tied to the wall socket earth, b) monitors also tie HDMI cable ground to earth, and so c) my lash-up now had dueling grounds that were 9V apart.
