When I was in the market for a new machine, I had the same attitude. As I was about to hit "Buy" on a standard issue $2k MBP, my wife said, "What if we got you a top of the line machine?"
I replied that it would make no sense unless I was going to start running local inference or training my own models locally...
2 years later, and this MacBook Pro M4 Max w/48GB is the best $4k I've ever spent!
...that's...not how exponents work
While poetic, I suspect that the utility of including this in the prompt is much more pragmatic: models refined on datasets of turn-based interactions will have weights biased toward checking in with the "user". Saying "believe in yourself" probably introduces just enough of a counter-bias to push the model into a local basin of deeper thought.
Yes, Tylenol's molecular method of action has never been experimentally confirmed.
I have no particular dog in this fight, but I thought it might be pertinent to point out that we still don't know the exact mechanism behind why Tylenol works...

In graduate school he had a reputation for being the best at synthesizing LSD.
If you think Kekule's story is wild, you should read about how Kary Mullis came up with the idea for the polymerase chain reaction!

terminal-code has been replaced by a shell script which 1) Generates a syslog message at level LOG_EMERG; 2) reduces the user's disk quota by 100K; and 3) RUNS ED!!!!!!

When I was in graduate school, I was doing a lot of molecular dynamics simulations, but I did not have access to a lot of high-performance hardware. The math department had a 4-node Cray that was impossible to reserve time on, and the CS department had a 16-node Dell cluster that ran SGE and was decently reliable. When those resources ended up not being enough for my crazy array of tasks, I got resourceful and started gathering every single outdated CPU anyone anywhere on campus was getting rid of or had no use for, and built my own cluster in our lab. Before finishing my Ph.D. I had 12 SGI Indys, 8 PowerMac G3 6300s, 10 PowerMac G3 7600s, and 20+ Dell P3 towers in my "cluster".
NetBSD is the only thing that made that possible.

I've been working on RVW, my adaptation of the standard transformer model that is capable of online continual learning without catastrophic forgetting. I finally published the first pre-print of my early experiments:
https://doi.org/10.5281/zenodo.20064617Now I'm working on expanding the work into more parameters and improving performance. I just finished an extremely harsh test of a Nemotron-flavored RVW that consisted of stretches of a random assortment of domains interspersed with long runs of single domains. Across all of it the model didn't forget (and actually improved on some of the more challenging domains). PPL on SmolTalk is still in the ~18 range, which I'd like to get lower, but this is all with only 4B params.
Currently, I'm training a Llama 3.2-flavored RVW with only about 2B params to see how that turns out. Depending on results of that, I may take it to Gemma 4 next.

IIRC, there was always a way to filter out certain messages (or that may be an alt.org customization, but it's been a part of my config file for a while now).
For real! Valkyrie is the perfect "just bash things while only half paying attention" class. Great for when I'm playing to unwind (as opposed to playing as a challenge to myself).
At least there's still Samurai.
I think Douglas Adams had one of the best quotes regarding observing infinity:
"Infinity itself looks flat and uninteresting. Looking up into the night sky is looking into infinity – distance is incomprehensible and therefore meaningless."
It's been a while since I worked at Apple, but back in the day the entire OS X Server team made extensive use of kerberized NFS shares for moving around large files...
...the last version of Server shipped in 2021 (and the last real version shipped almost a decade before that).
My first job after finishing my undergrad degree was performing quality analysis on corn starch. As a condition of employment, I had to sign a paper saying anything I invented related to corn was property of my employer.
It's been more than a few years since I worked at Apple, but they were always unique in the tech space in that their retail division dwarfed headcount. If I recall correctly all of OS X Lion was produced by around 3,000 engineers (and probably less, since I think that count included iLife and iWork).
I've been working on an ML model capable of robust continuous learning, resistant to catastrophic forgetting without relying on replay, an external memory system, or unbounded parameter growth. Last week I confirmed the first non-toy, 580M parameter version soundly beat LoRA, EWC, and full fine tuning. This week I'm scaling up to 4.4B parameters...
We need benchmarks that can distinguish between continuous learning and long-context extrapolation.

Let's say, hypothetically, that you had a model that did not need to re-train in order to incorporate new information in its weights. What would you do with such a model?

Just what the title says: I'm wondering why we're still, years after ChatGPT, having to wait weeks or months for "the next version" of a model when so much else in the software world has moved toward continuous improvement?
Based on what you've already mentioned, there's a good chance you're familiar, but on the off chance you're not: "Funkungfusion" (or, really, anything off the Ninja Tune label) might be right up your alley.
Eh, I'm not so sure it'll be that big a deal. The whole supply chain is so twisted and tangled all the way up and down. Shuffling out one piece doesn't seem like it will, on its own, be so major. Samsung made the chips for the iPhone, then made their own phone, then Apple designed their own chips made by TSMC, now Apple is exploring the possibility of having Samsung make those chips again.
Also, it takes a willful ignorance of history for ARM to claim this is the first time they've manufactured hardware. I mean, maaaaybe, teeeeechnically that's true, but ARM was the Acorn RISC Machine, and Acorn was in the hardware business...at least as much as Apple was for the first iPhone.
Fun fact about that cannon: it took so long for the cannon to cool off between shots that the Byzantines were able to patch each hole it caused before the next shot.
