I'm tourist in Zig land too, follow Kristoff / A. Kelley etc, Tiger Beetle DB (written in Zig) and stuff, but only as observer / bystander.

Last time I check an NVidia situation was for DGX Spark (the GB10 chip), it has regular LPDDR5X which by JEDEC standard cannot go beyond ~270 GB/sec, ie 8533 Mbit/s on a 256 lanes bus.

So yeah Lemire seems to go "OMG unified memory, they're following Apple path..." ok, but Apple pulled off a much faster interconnect, 800 GB/s ballpark, and I'm trying to understand (not really, I'm asking you to try understand, he he) how is this laptop faring in that regard.

In his role, devising as set of general guidelines to use as compass when things (inevitably! and often!) get very very muddy and Right v. Wrong is hard to tell apart -- both objectively, and also from the point of view of being a community leader with ton of vested interest -- is essentially one half of his job. Other half is abide to said guidelines.

So @kristoff_it last week sat down, came up with three simple rules short enough he can print on a business card (or hang on his office wall or whatever), and posted them here to test if they make sense to the wider community.

TLDR: yes can seem bland / generic but within context it makes sense to me author needed to distill his ethics in a nutshell.

Yes of course that was a brain fart of mine. Watt is Joule per second not certainly Joule per hour. I made the point of "lecturing" readers on power v. energy since Antirez (OP) wrote _"50W of energy usage..."_ (instead of power consumption) and it's a mistake people often make. So my side point was: ok 50W but for how long.

The other thing I'm arguing is 50W is nothing to be shocked by. I would like to see an argument for the opposite. I'd like to know what's the power consumption of playing eg. Baldur's Gate for a couple hours on a gaming rig and I wager we surpass that by a margin.

Now, the data center economy of scales. You're saying they almost certainly exists. Okay whatever I don't know. Requests served in parallel. Amortizing memory access for model weights. Likely. I'm writing this with some thinly veiled dismissive attitude because I believe that it would be very useful to have hard data on whether or not serving many users v. just one user makes LLMs more efficient. It's an important point with wide ranging implications.

If there is scale, like you claim, and one day a wealthy patron gifts me a 40k USD rig where I can run a frontier LLM locally, then I'd still be making selfish use of the commons (energy, which belong to the planet, all of us, that kinda stuff) because the efficient/responsible choice is to pool and use a cloud vendor (or pool your rig with neighbors etc).

But saying a machine can be more efficient if it serves many users sounds to me a bit like nine women making a baby in a month.

Washing machine 900W. Hair dryer 1500W. Pizza oven 2000W. So yeah, you say 50W, yeah sure same as video rendering or gaming I guess, yet not really an OMG-level number.

And frankly I'm not quite sure there's anything like economy of scale where it gets more efficient if you serve more users (like some sibling comments seem to imply).

Last thing, and I know many know but also many others don't or have forgotten: Watts is a rate of consumption, not an absolute amount. That is Joule, energy. So you say 50W, but what you pay for (or the planet pays, whatever) generally is the amount of energy, hence you need to say for how long that consumption was sustained. 50W over 2 hours, that's 100 Joules, the actual resource you consumed and paid for.

Power (watts) is like speed (m/s). You say 50 miles an hour, need to say how long was the drive, so we know how far you got.

I have to say, I don't identify myself as a anarchist (maybe a bit of a sympathizer), yet I'm middle aged and finding myself a little dissatisfied by many things I see around me, so if I see people making the equation anarchist = degenerate, my immediate reaction is "yeah let's slow it down shall we."

Now, I'm aware that when you need to say something is "gateway" that's a bit of a red flag, i.e. "milk before meat" (describing something as friendly and innocent at first, then only later showing the more aggressive indoctrination) is exactly what cults do. Having said that, I'd grant that the late David Graeber is quite the straight shooter so I think he's in the clear here.

From the looks of it, this seems like a serious corporate backed project made by employees of the Ant Group, the chinese fintech giant. A more fair comparison would be with Google's Fuchsia OS (defunct) or Huawei's HarmonyOS. It may succeed, it may fail, but it's nothing like a couple of kids doing a passion project to learn Rust.

I've learned the acronym here on HN, googled for a second and found "the fine article" as explanation, but now that you ask I've checked wiktionary... and apparently the commonly accepted meaning is derogatory (the f*king article, like "RTFM", "read the F-ing manual).

Lesson learned, won't be saying "TFA" again unless I mean f-ing

I've never used one, but I assume there are professionals for hire to do this.

In fact I've read one of the advantage of going with a publisher (as opposed to self-publishing) is they give you an editor. But again, I'd expect a freelance market to exist.

"A monad is just a monoid in the category of endofunctors."

Maybe it is, maybe it isn't, but none of that is simple. There's that math joke about proof methods, and this would be "proof by intimidation".

When describing a process: "To measure the inverse reactive current in unilateral phase detractors, just use an ordinary turbo encabulator". Why "just"? Are there other methods? For what reason is this the preferred one?

When giving advice: "Why don't you just use a bash script?" This implies your suggestion is simpler or more economical than my proposed approach, therefore better, but you aren't supporting its alleged superiority with arguments I can counter, only implying it.
