Battery life is shorter, and some are a tad heavier.

Doesn't just emacs render to a tty?

Or is this for some Emacs build with its own renderer?

Effort. AI is low effort, which signals you really don't care, you're out there for a quick buck.

It's insulting. It makes people feel irrelevant.

Apple doesn't like to be held hostage, it has the cash coffers, so it wouldn't surprise me if they're somehow buying dedicated production capacity for the future.

Not that they will start making memory themselves, but they have bankrolled production expansions in their suppliers before in exchange for guaranteed supply.

In any case, if my guess is right, it would take years to take effect.

90% of my model use is on local open-weights models.

The things that I need to automate do not need frontier models. Heck, even a gemma-4-12B-it-qat-UD-Q4_K_XL can deal with a lot of complexity if properly guided (it can run on 16GB of unified memory, for example on a base model Macbook Air).

I've been using it to translate Javascript to a custom scripting language in a product I work for, just by providing a system prompt and an MCP tool to call the target compiler to check for errors.

Sometimes it converges faster than Opus 4.6 (I've tried) because it doesn't over-think stuff.

If it were a person I would say it knows less, but it's still smart.

I mean, you don't need the most powerful tool at all times. We treat AI as one-size-fits-all, and once cost gets in the way, it will matter.

All leadership is like that. Even if you're not a people manager.

I'm an IC in a technical leadership position, all of these hold true with the added constraint that I cannot tell anyone what to do. I hold no carrot or stick.

I have to persuade, convince and influence, I have no reports (nor I want them) so to get anything done I need to get people to align and understand the value on its merits.

That's always an issue, but the industry seems to be moving away from 2D circuits.

Reducing trace length seems to be the way forward for faster/larger circuits. Signal propagation time on-die is becoming an issue.

Things like Huawei's Logic folding, or TSVs, and so on, attack the issue by reducing signal travel time.

This looks like another building block in that direction.

There's also some push at cooling chips from both sides.

Yeah, but it was probably the right call at the time.

Backward compatibility was a breath of fresh air at a time were code needed constant porting and rewriting. No two machines were alike.

It's one of the reasons the PC became so popular.

Everything is within spec, reproducible builds are not a goal of C/C++.

The compiler builders may take pity on you, but really there's no bug here, just unwarranted expectations.

It's still too unpredictable trying to be transparent IMHO.

Scalarization can fail in surprising ways just due to what a maximal atomic write can be on the target platform, and then it fall back to heap allocated objects.

Even if there's type erasure.

I much rather have the compiler balk at me than let me write something that may or may not work as expected.

The triple click is annoying.

I mean, select the word, then press check, then press continue.

It could be one single click and move to the next, show me my last result at the same time you ask me for the next one.

The influence has spread wide, there's one even in Buenos Aires: https://buenosaires.gob.ar/gcaba_historico/jardinbotanico/la...

I'm trying to figure out exactly how to best use AI, but not just as a chatbot user.

How to integrate it to solve useful problems. Make delightful products.

So many things that used to be intractable now are probabilistically solvable and that needs some things to be changed fundamentally and a lot of assumptions dropped.

The randomness that AI introduces poses a plethora of challenges.

I think local models will be a big thing eventually, not everything needs a frontier model and a lot of useful work can be done with surprisingly little hardware.

I also want to get back to non-LLM models.

It's like the e-everything trend of the 90s.

It's pushing an internal tech detail onto customer faces that only care about a problem being solved.

It's virtue signaling for investors and a usually misguided attempt to look trendy or cool.

It's kinda like that, there could be a proprietary fraud detection heuristic in there that you don't want to get out.

The most important thing a human translator does is certify that the translation is faithful.

Period.

You could do a machine translation if you want, but you better pore over every word in case you end up on the witness stand.

Not really, I've been using linux since the Slackware on diskette era. I know my way around recompiling a kernel (used to do it on a 486).

I also did dev on Windows, I know the internals pretty well (I even did embedded on CE, writing portable code across CE/95/NT family runtimes).

I still prefer Mac, it's much less likely to randomly break, mainly due to the fact that the hardware the software runs on is extremely predictable. I also like the care about muggle usability that Apple tends to pursue (granted, not perfect, but way better than the other two)

Like I care. I'm not that interesting.

They get updates forever, and even after they're usable anyway.

They even get serious security updates even after that period, and you can install linux if you really want to, but it makes no sense to me.

The issue is when it updates.

The moment it runs an update all bets are off. It's always audio for me, it breaks in the weirdest ways.

Mac updates are the best in the industry, period.

Close to zero chance of having an issue (unless you're messing with third-party kernel extensions).
