jarbus··on Why isn't the industry freaking out about DeepSeek 4.1 Flash?
Thank you for posting this, I didn't realize just how good 4.1 flash was. it far surpases gpt-luna in the limited testing I did: luna would take so many tokens that implementing a new feature would be nearly as expensive as if i just did it with sol 6.1, but 4.1 flash can do it for basically 1/6th the price, if not less. Obviously depends on the feature, but very very impressed.
jarbus··on Navier-Stokes – Tristan Buckmaster [pdf]
The ego behind the frontier labs is growing evermore concerning
jarbus··on Building Without Predicting
This sounds so interesting and fun. I’d love to do something like this but I lack the experience in construction to actually pull it off. Also, I like to host, and I feel that this kind of lifestyle is incompatible with the average person, who probably wouldn’t want to visit for more than an hour.
jarbus··on Thoughts About Scaling Law
Maybe just me, but I have a feeling that we are currently stuck at 100-200k effective context window due to a parameter limitation, specifically the hidden dimension of the model, which would be an incredibly expensive dimension to increase vs adding optimizations elsewhere. I don’t think we are done scaling parameters yet.
jarbus··on Fairphone is now officially available in the United States
Praying that fairphone somehow makes a foldable one day. My next phone will probably be a fold 8 because I really want a nice reading experience on the go, but I love the philosophy and love my framework laptop.
jarbus··on Retire the Abstractions
Personally I think we will just become more ambitious with our abstractions since the LLMs can generate more complex stuff at the lower level. To take the article's examples, LLMs will write kernels that fuse 3+ layers of a model, so the abstractions can enable more complex forms of kernel fusion.
jarbus··on I'm switching my phone from Android to Linux
I really want to love mobile Linux, and have given it multiple shots before. But I just don't see how it will catch up with iOS/Android in the same way it caught up with Windows/Mac:

- OEMs have poured an enormous amount of resources into the camera software, Linux cameras are years behind from what I understand. - Android/iOS have thoroughly optimized the UX in all sorts of subtle ways, the big one being their keyboards. I literally can't type a single correct sentence on any of the mobile linux keyboards that I've tried because there's so much proprietary magic needed under the hood to figure out what the user is trying to say (autocorrect mostly, but I recall something about how apple also virtually adjusted the sizes of the keys to make it easier to type) - GPS, banking, and now keys for your house and car all need to work.

jarbus··on Why is everyone trying to build a solid-state battery?
I’m still a novice on the material science behind it, but what is QuantumScape lacking here if anything, and why is it a dealbreaker?
jarbus··on How to write English prose (2023)
As someone who generally liked the article, this is perhaps the strongest argument against it. Prose like this requires even native speakers to really focus. I wouldn't write this way for anything intended to be read by an unknown person.
jarbus··on UnifiedIR for Julia
I was unaware of alternative IRs for julia (albeit I started learning much more about compilers once I left the julia ecosystem). What other IRs is this supposed to replace? And why not just go with MLIR directly?
jarbus··on Phosh 0.56.0
Thanks for sharing your experience, I'm glad to hear that mobile linux is practical for some people. What do you do for GPS? And in day-to-day use, doesn't WayDroid drain the battery?
jarbus··on Phosh 0.56.0
Tap to pay isn't itself a dealbreaker, for me it's more a representation of the status-quo and what is to come, specifically how more and more of the modern world will rely on integrations with proprietary software and hardware on phones. Tap to pay with credit cards isn't too big of a deal, but the wallet as a whole (i.e. boarding passes for airplanes, gift cards, ChargePoint tap-in) is a major feature.
jarbus··on Phosh 0.56.0
Linux has long been the most practical laptop OS for me, but I can't see it ever being competitive with mobile OSes, and that's coming from someone who wants it to succeed (I've installed postmarketOS on a OP6T). I just don't see how it will overcome the various issues (app support, tap-to-pay, camera quality, etc).
jarbus··on From Julia to Rust: a differentiable tensor stack for scientific computing
really interesting perspective, as an ex-julia user, can't really argue with the main points. I will say that julia is delightful to use and code in, whereas the article's main point is that rust becomes bearable once you don't have to code yourself, haha.
jarbus··on Show HN: 10x better performance from the Coding Harnesses with LLM-wiki
Where is this 10x number coming from?
jarbus··on A Git forge for the agentic era
Is the site broken for me, or is there literally zero information on what this is besides the title of this HN post? I’ve never seen a waitlist for such little information
jarbus··on TurboQuant: A first-principles walkthrough
This is incredible. Interactive demos like this make mathematics 10x more accessible
jarbus··on I'll buy your electronics to feed our robot
This is really cool. In the demo, how do they just yank the chip off the board? I'd have assumed it would be somehow soldered on or something.
jarbus··on The behavioral cost of personalized pricing
This is why I like buying in a physical store. I also think the only solution to this practice is really just to avoid buying as much as possible. I never get food delivery and only get uber to go to and from the mechanic. Ditto for the medical system, I got charged $400 for a strep throat test. I’ll just stay home until I feel better
jarbus··on The truth Elon left out
I think the court of public opinion also matters greatly to be honest, especially when you are responsible for a dangerous technology
jarbus··on Think of Pavlov
It can be an exhausting way to view relationships, but I think it’s true. I’d argue there also is plenty of room for intimacy and vulnerability when it’s genuine. I think people appreciate these traits when they are genuine and appropriate, and prefer it to a fake aura of confidence
jarbus··on The Gentle Seduction (1989)
Didn’t realize we could post short stories on here. This one was really nice :)

I wrote a similar sci fi short story set in the near future if anyone is interested:

jarbus··on Toad is a unified experience for AI in the terminal
This looks really cool. I wonder if they support vi keybinds
jarbus··on GNU Unifont
Been a proud user for a while at jarbus.net :)
jarbus··on Evolution Strategies at the Hyperscale
This is pretty cool :) I had worked on a similar project earlier this year, but applied to GA and not ES

jarbus··on Unison 1.0
This is so so, cool, but I feel like most of the features are lost once you need to use complex dependencies that aren’t in unison.
jarbus··on What I learned about creativity from a man painting on a treadmill (2024)
Love this. I feel this narrative is woefully under-appreciated. I think there’s something beautiful about watching people who aren’t near the top of their field, “normal” people who are just trying to have fun. But that doesn’t make a good story usually. I’ve tried writing some fiction along these lines, and it requires quite a bit more narrative to convey.
jarbus··on Helion: A high-level DSL for performant and portable ML kernels
I posted this 5 days ago, how did this resurface?
jarbus··on Terence Tao: The role of small organizations in society has shrunk significantly
Side tangent, but I absolutely love how Tao uses mastodon
jarbus··on Are we decentralized yet?
Mastodon has been great so far
