Ed Zitron Voice: Is that good?
hengheng··on Don't throw away your old PC–it makes a better NAS than anything you can buy
Depending on how you build it, you could run homeassistant next to your smb, which lends itself to all sorts of add-ons such as calibre-web for displaying eBooks and synchronizing progress.

Of course, gitea and surroundings, or similar ci/cd can be a fun thing to dabble with if you aren't totally over that from work.

Another fun idea is to run the rapidly developing immich as a photo storage solution. But in general, the best inspiration is the awesome-selfhosted list.

hengheng··on General principles for the use of AI at CERN
In your opinion, what would instead justify the total cost of devoting 10'000 people's lives to basic research?
hengheng··on General principles for the use of AI at CERN
That is equivalent to a continuous draw of 150 MW. Not great, not terrible.

Far less power than those projected gigawatt data centers that are surely the one thing keeping AI companies from breaking even.

hengheng··on Free interactive tool that shows you how PCIe lanes work on motherboards
Look into CXL, Oculink, and riser cables.
hengheng··on AMD continues to chip away at Intel's x86 market share
How's AMD's engineering support these days? I've heard through the grapevine that many laptops were mostly engineered by intel engineers, creating a natural moat because the laptop brands are used to not having to do much PCB layout or thermals.

AMD, I heard, seemed less capable, or less interested, or couldn't justify at their quantities, to do the same, which meant their engineering support packages were good for atx mainboards only, and maybe the occasional console.

This must have changed a while ago, does anyone have the tea?

hengheng··on Tiny electric motor can produce more than 1,000 horsepower
I agree insofar as the motor is not a Big Ticket Item, opposed to ICE cars where the engine block is going to be 10% or more.

Tesla (I know) claimed a 30kg (?) weight loss on their Cybertruck (I know) just from moving their 12V systems to 48V, allowing for lighter cables at lower currents. Not all such potential is untapped, and my hunch is that there is more to be had with structural battery integration, battery cooling, and high voltage wiring.

hengheng··on Trump directs nuclear weapons testing to resume for first time in over 30 years
To me the real question is what kind of trust has eroded that Americans stopped electing smart people into office.
hengheng··on 10M people watched a YouTuber shim a lock; the lock company sued him – bad idea
That explains so much. Done to well for a goof channel, eclectic assortment of skills ("tactical garden trowel" vs fully equipped metal shop vs perfect video production), all fat trimmed off the videos.

I kinda want tvtropes to put a name on his slapstick humor. It's like looking over the shoulder of that weird uncle that seems to live in an entirely different world.

hengheng··on Intel Announces Inference-Optimized Xe3P Graphics Card with 160GB VRAM
How can you tell without knowing the bus width?
hengheng··on Ryanair flight landed at Manchester airport with six minutes of fuel left
Write it as a children's book. A literal ELI5.

(Knowing, of course, that it will still be read mainly by engineers. But that's the charm.)

hengheng··on BYD builds fastest car
Chiron still has that Piëch handwriting on it. It's driveable enough to take your wife to the opera. Full regulatory compliance, low wind noise at high speeds, all that. I don't want to say it is compromised, but it's not as extreme as it could be.

The closer ICE comparison would be Koenigsegg (447 kph/278 mph), Hennessy Venom GT (435/270) and SSC Tuatara (455/283, no shenanigans). SSC have reached 295, they were clearly aiming for 300. It's no 308 but it's reasonably close.

All these are also relatively small companies with relatively low budgets -- none of the big manufacturers seem interested in top speeds anymore.

hengheng··on Building the heap: racking 30 petabytes of hard drives for pretraining
> we prob don't want to have it in Europe

Best indicator as to what that is.

hengheng··on Building the heap: racking 30 petabytes of hard drives for pretraining
My guess is automated surveillance, which is also where this whole play has to be headed.
hengheng··on US to retire its only icebreaker, stranding polar research
Has the research aspect ever been more than a fig leaf and a "might as well"?

Strong parallel to rockets and high-altitude planes used for atmospheric research ...

hengheng··on 25L Portable NV-linked Dual 3090 LLM Rig
I've also learned the hard way to Google "AM4 main board tier list" before buying.

Some boards can run a 5950X in name only, while others can comfortably run it close to double its spec power all day. VRMs are a real differentiator for this tier of hardware.

(If anyone can comment on the airflow required for 400-500W Epyc CPUs with the tiny VRM heatsinks that Supermicro uses, I'm all ears.)

hengheng··on Meta Ray-Ban Display
I don't even think it's cynical anymore to assume that this is the entire reason why Meta are pursuing this.

They see themselves in a race to produce the most radical, most efficient machine that produces the most effective addictive response. Content has been interchangeable for decades, everything is about the naked control over people's attention, because that is having power over people.

There is a very modernist logic in the whole effort. Everything must be taken to its extremes, nothing is ever enough, and nothing good sits in the middle of anything, and having values is only a detriment in this race.

hengheng··on Learning Lens Blur Fields
I can't imagine there being enough information for true fingerprinting of individual devices. With ten million iPhones being made per month, surely the blur patterns have to have some overlap?
hengheng··on Google to obey South Korean order to blur satellite images on maps
It's the same with military sites in France, where satellite images are blurred but you still get street view, and if that doesn't exist, you can still look at ground level photos, like so https://maps.app.goo.gl/Kr2822pASFRPLJHR7

Compliance is fun.

hengheng··on Intel Arc Pro B50 GPU Launched at $349 for Compact Workstations
Needs a PCIe bifurcation chip on the main board for all we know. Compatibility is going to be fun.
hengheng··on Garmin beats Apple to market with satellite-connected smartwatch
On my Fenix 6, Bluetooth volume control broke after a few years, and now the volume slider does nothing, which the hivemind confirmed.

So, it is in fact worse than not getting upgrades, the software actually deteriorated over its lifecycle.

hengheng··on US Intel
I've seen US startup people deal with manufacturing. There is a class gap that leaves no real space for skilled blue-collar work to exist and also be business critical, and fully integrated into the team. That is how a three-week turnaround for a milled prototype part ends up being tolerated.
hengheng··on Hand-picked selection of articles on AI fundamentals/concepts
Surprised to see something on hackernews that isn't an AI picked selection of articles :-)

hengheng··on Benchmark Framework Desktop Mainboard and 4-node cluster
The recent qwen3 models run fine on CPU + GPU, and so does gpt-oss. LM Studio and Ollama are turnkey solutions where the user has to know nothing about memory management. But finding benchmarks for these hybrid setups is astonishingly difficult.

I keep thinking that the bottleneck has to be CPU RAM, and for a large model the difference would be minor. For example with an 100 GByte model such as quantised gpt-oss-120B, I imagine that going from 10G to 24G would scale up my tk/s like 1/90 -> 1/76, so 20% advantage? But I can't find much on the high-level scaling math. People seem to either create calculators that oversimplify, or they seem too deep into the weeds.

I'd like a new anandtech please.

hengheng··on The future is not self-hosted
I can't see community-hosting taking off. I do not trust anybody telling me about E2E encryption that I can not prove.

I barely trust Google.

I trust the long bearded neighborhood nerd much less than most companies. Even if I probably am that person in my neighborhood. But nobody should trust me, and I am not going to tell them to trust me.

Even if everything is encrypted, I can almost guarantee that the community shared server will be confiscated by the police once in the next three decades.

hengheng··on Show HN: Tinder but it's only pictures of my wife and I can only swipe right
Can't try because Android phone best phone, but I already have a request.

Can we get messages? It isn't that uncommon where I live to have several instant messaging apps, and having a separate channel for chats with my partner is actually great. Easier to manage alerts and notifications, doesn't mix with the other channels, etcetera.

hengheng··on How Tesla is proving doubters right on why its robotaxi service cannot scale
That was the moment the veil was lifted.

There's a model Y with The Sticker on it in my street, introduced years after he showed his colors like that. No, dear neighbor, when you bought that car, you knew.
