> what computers are you buying that are more environmentally friendly?

Any computer that you can upgrade its parts? SSD, RAM, Wifi cards, etc.

The only parts that wear out on a modern laptop are the SSD and the battery. If I replace those, I can use it basically indefinitely, paying the penalty on performance and energy consumption depending on how old the CPU is.

Why would I throw out (or recycle) a perfectly good computer if I could simply fix or upgrade it? If you're not reusing it, then you could pass it down to somebody who would use it.

20+ year old computers are e-waste at this point thanks to software bloating and lack of hardware acceleration for at least h.264.

15 year old computers are very usable, but unfortunately most use SATA for storage which is definitely not optimal for SSDs.

10 year old computers are from when PC tech plateaued, for most use cases the difference in performance is imperceptible, and maybe you lose power efficiency.


nowadays macbook batteries aren't something i'd call "easy to replace" but it's not something a typical repair shop or meticulous individual wouldn't be able to do – most beater windows laptops don't have user-replacable batteries either fwiw

if the ssd is bricked you do need to replace the whole "logic board" tho which sucks


I miss the glowing apple on my white polycarbonate MacBook. What I don't miss is the shitty Intel GMA X3100 iGPU and Apple not releasing a 64 bit driver for it.

Should have spent the money on a MacBook Pro with a real GPU, I would have used that computer way longer than I had.


I miss the glowing logos too, but I guess this would force the screen to be ticker, which is a big no-no for Apple.

I think this April they should announce one with a beige shell, a rainbow logo, and a brown keyboard (with BELL on top of tge G) ;-).


Eh... Prohibiting access to MSN Messenger on school computers was one of the catalysts to me being a highly paid professional today.

Tell children they can't do X, some will find ways around it, tell their friends the workaround and maybe even get a profession out of it. Who knows, maybe one kid will find a text editor and a compiler laying around somewhere...

Fuck, I even tried to learn Russian by myself just to understand those old hacking forums. At least I got proficient in Cyrillic. I don't have children, but definitely I'd direct them to learn reading Chinese.


I have a personal 16 GB M4 Macbook Air and my wife’s work computer is a 24 GB M4 Macbook Pro. My laptop runs circles around her work’s.

Companies install so many invasive shit in the name of security theater and employee control that there is lots of waste going on.


If you ask an LLM to code whatever, it definitely won’t produce optimized code.

If you direct it to do a specific task to find memory and cpu optimization points, based on perf metrics, then it’s a completely different world.


You can also tell it the optimization to implement.

I asked Claude to find all the valid words on a Boggle board given a dictionary and it wrote a simple implementation that basically tried to search for every single word on the board. Telling it to prune the dictionary first by building a bit mask of the letters in each word and on the board and then checking if the word is even possible to have on the board gave something like a 600x speedup with just a simple prompt of what to do.

That does assume that one has an idea of how to optimize though and what are the bottlenecks.


Can we assume at this point if the problems are well known, the low hanging fruit has already been addressed? The Boggle example seems like a pretty basic optimization that anyone writing a Boggle-solver would do.

iOS is 19 years old, built on top of macOS, which is 24 years old, built on top of NeXTSTEP, which is 36 years old, built on top of BSD, which is 47 years old. We’re very far from greenfield.


If shipping then yes, customs got stricter thanks to Shein.

If flying then you can bring up to 1000 USD of stuff tax-free every 30 days. On top of a personal phone and watch. Plus 1000 USD of stuff you can purchase at the duty-free shop once you land.


If you left with a phone (pretty mic required), you can’t come back with an extra iPhone - since those are typically > $1000.

Of course, people will. It’s mostly the folks bringing back 5 new phones or whatever that get nailed. But mostly they only care if you’re obviously Brazilian of course hah


Yeah, this is more pronounced with watches.


Yeah, I now need a pyroceram skillet too!

But as the solo meat-eater human in my apartment, I ended up buying a gas-canister camping grill to barbecue steaks on my terrace on weekends and then I reheat the rare steaks through the week in the microwave. They get the Maillard reaction and flavor, they get to the correct doneness point when blasted with RF later on.

Cats get happy with the barbecuing, I also grill mushrooms and tofu for my wife and it’s very easy to clean afterwards.


Coleman stove. Mine lives in the back of my elderly Range Rover along with the recovery gear, a kettle, some dixies, and some basic staples (tea, coffee, aeropress, instant noodles). I've always got a few litres of drinking water, and in any case I live in Scotland where you're generally not terribly far from perfectly drinkable water that's just sitting right there on the ground often spilling majestically over rocks and waterfalls which are slippy as hell when you go to fill the dixies and which you will get to experience right up close, considerably closer than you intended.

There is nothing like sitting on the tailgate up at a remote hilltop site on a pleasant spring day, drinking a cup of tea outside in the sunshine while you wait for the third attempt at a firmware recovery on a radio repeater to finish, contemplating chucking some sausages on for lunch.

Except, possibly, sitting inside the transmitter shed has it gets buffeted by storm winds listening to the rain battering against the roof and drinking a nice hot cup of cocoa as you wait for the 17th attempt at a firmware recovery to finish.

And if you run out of the expensive special magic Coleman fuel, it runs just as well on mogas so you can pop the inlet hose off the injector rail, scoosh some into the stove tank, and get right on back to cooking your dinner.

Me? No, I'm going to be out on site all day long, I won't be in your Teams call. Tell you what, want to come with? It'll be good for you to see some of the hardware in use. Grab a steak or something to do for lunch.


Many of my good memories of youth have a green coleman stove with the red fuel tank somewhere in sight. I was often the one tasked with pumping it up.

[edit] youth...not you. That read weird.


I do not care much about the Maillard flavor, so even when I was using a gas grill I was using the kind with indirect heating, where the grill is enclosed in a box that has one opening on the bottom, where you put the flame. The opening is laterally from the grill, not under it, and it has a wall separating the grill from the flame.

With such a grill, the meat is cooked only by the hot air that comes from the flame without contact with something at higher temperatures, so the meat is browned only moderately at most.

Nowadays, I can cook meat in a microwave oven in a way that makes it pretty much equivalent with the meat cooked using that kind of grill with indirect heating.

I cut the meat in bite-sized pieces and I put them in a glass vessel covered by a glass lid, without adding water or anything else, except salt and seasonings spread on the meat.

Then I cook the meat in the microwave oven, using a low power, e.g. 400 W, and long times, e.g. 20 to 25 minutes for chicken meat and around 30 minutes for turkey meat.

I consider that meat cooked in this way has an optimum taste, but of course preferences vary.


I think it does more harm than good on recent models. The LLM has to override its system prompt to role-play, wasting context and computing cycles instead of working on the task.


Hah, yesterday I was discussing solar panels and moving shadows. I would have wasted money buying a commercial solar panel if I didn’t have this chat.

Learned a lot on how it works, to the point I’m confident that I can go the DIY route and spend my money in AliExpress buying components instead.

Why not ask a pro solar panel installer instead? I live in an apartment, of course they would say it’s not possible to place a solar panel on my terrace. I don’t believe in things not being possible.

But I had two semesters of electronics/robotics in my CS undergrad and I know to not to trust the LLM blindly and verify.


No need, at least when I was there when the day was still one, before the pandemic. And well, Firecracker is open source.

A few of the best technical presentations that I've watched were at a pre-SKO event. Nitro, Graviton and Firecracker.

Great engineering pieces, the three of them.
