GZGavinZhao — Wed, 03 Jun 2026 16:28:19 +0000

My reMarkable is still stuck on a super old version (v3.3 I think), precisely because of xochitl being closed source and there's no stable and efficient way of driving the display. It's super sad because I would love to have much more things appearing on my tablet yet I cannot develop reMarkable apps easily. I'm not talking about browsers, but more like my Linear TODO list, calendar, etc., so I don't have to reach for my phone.

I really want to try for further reverse engineering of xochitl now that I've heard those AI tools have gotten so good at doing it.

Man I really wish one day I could run mainline Linux kernel on this tablet with the display just works.

Yeah as much as I like Prusa, I really hope they figure out how to cut down their prices because, let's be real, most of the people buying a 3D printer don't give a cent about how "open" it is, and if Prusa continues this trend I'm afraid it'll become obsolete. Having competitors with genuinely good products (like Bambu, despite them not being a good company) is healthy, but not helpful if Prusa doesn't do anything to catch up to their competitor.s

Oops my bad, I mixed up Flashforge and Snapmaker. It was Flashforge that also started closing down their ecosystem. Snapmaker has been having a good track record so far with their open-source Klipper-based firmware and I hope they continue to do so!

I assume you're into multi-material printing and want a true multi-extruder setup. Then, quality wise your remaining options are: Prusa, Flashforge, and Snapmaker. Snapmaker very recently just shot themselves in the foot in a similar way that Bambu did, so you're left with Prusa and Flashforge. Of the two remaining, I really only trust Prusa.

Yes you pay a lot more, but I guess that's some sense voting with your wallet... I'm personally going to buy a Prusa after I stabilize where I live.

My understanding is that you got your printer when the firmware was not blocking you from doing all of that. Right now if you want to remote print (and don't want to do it via sending models to Bambu Cloud), you can get away if you enable LAN only and developer mode. However, what if the newer firmware forces you to create an online account and connect to Bambu cloud to do the setup? What if Bambu decides to limit the features you can use if you print using a SD card? It has been quite a worrying trend, and now the company is trying to legally threaten an open-source developer building on top of Bambu's AGPL code trying to make remote print without going through Bambu servers possible. Other ppl more knowledgeable on the issue, please correct me if I'm misunderstanding the situation.

It's always sad to think what more can be achieved / how faster we might've arrived at M3 support if Asahi Lina is still active.

*sad Android noises

Maybe some folks more familiar with iOS can comment on how reliable this is on the software side. For example, what's stopping me from feeding a video stream as camera input?

Speaking from personal experience, 99% people/students don't, and that is the problem.

I want one for HiFi headphones / IEMs! I feel really bad to order two or three models that I want and have to return all but one, because I can't really tell the difference just by looking at the specs sheet. My ears should be the ultimate judgement.

As always, honorable mention to Typst [0] as a good balance between the readability & simplicity of Markdown with the flexibility & composability of LaTeX. I think and hoping that Typst will be the future, but for now I'm happy with Markdown.

Always baffles me why some people think and act like being proud of their state/country/race and criticizing its actions are mutually exclusive.

New comment by GZGavinZhao in "Async/Await on the GPU"

GZGavinZhao — Tue, 17 Feb 2026 19:53:54 +0000

One concern I have is that this async/await approach is not "AOT"-enough like the Triton approach, in the sense that you know how to most efficiently schedule the computations on which warps since you know exactly what operations you'll be performing at compile time.

Here with the async/await approach, it seems like there needs to be manual book-keeping at runtime to know what has finished, what has not, and _then_ consider which warp should we put this new computation in. Do you anticipate that there will be measurable performance difference?

New comment by GZGavinZhao in "Zulip.com Values"

GZGavinZhao — Tue, 10 Feb 2026 14:07:17 +0000

UI and user ergonomics continues to be Zulip's biggest blocker to wider adoption. I understand that to many people not having E2EE and truly independent self hosting (e.g. push notification issues) is a deal breaker, but for many organizations the current level of openness from its values is enough.

I really wish Zulip could find someone to re-design the interface around the channels/threads model to make it easier to use and more friendly to beginners. I am personally never bothered by the design and got used to its interface quite quickly, but I know many many people who got turned away by its design or uses it in a Slack/Discord way by posting everything into "general chat".

reMarkable just open-source your display drivers and E-ink render stack please. I'm pretty sure the pressure curve issue can be solved just by tuning a few parameters in the code. I appreciate reMarkable for adhering to GPL and giving us trivial root access to the machines, but while you're there I really don't see why you don't just do it fully.

Even with the limited amount of usability, the community has already made some amazing additions, for example KOReader. Imagine how far we'd get if we can just write any app we want for reMarkable. I would completely get a typefolio and ditch my laptop if I have the ability to *easily* write my own app on the reMarkable without going through the loops of binary patching and other quirks.

On Android there is a similar app called "Forest". I used it five or six years ago, not sure if it still exists now.
