Trying to see if I can implement psychoacoustic bass enhancements and other advanced DSP techniques to improve Linux laptop speakers.

HW video decoding is now available and by default on in Chrome on at least Ubuntu with my Intel iGPU. I was also surprised when they turned it on under the radar. I saw this the ot…

I actually made this patch a while ago on lineageos but lost the patch. It is a very invasive change where I filtered for the world amber and the French equivalent...

Does this impact the western digital and SanDisk brands too? IIRC those brands got folded into Crucial.

For single-threaded, cooperative multitasking systems (such as JavaScript and what OP is discussing), async mutexes[1] IMO are a strong anti pattern and red flag in the code. For t…

This is like fighting complexity with even more complexity. Nix and bazel are definitely not close to actually achieving hermetic build at scale. And when they break the complexity…

So I don't understand where the meme of the blurry super-resolution based down sampling comes from. If that is the case, what is super-resolution antialiasing[1] then? Images when …

Neat! I worked on a similar formal verification of Ghostferry, which is a zero downtime data migration tool that powers the shard balancing tool at Shopify, also using TLA+: https:…

Devil's advocate: my bridge fell down because I didn't know the concrete didn't meet spec still seem like negligence?

There is the kawai novus5 which is a digital piano with the action and soundboard of a real upright piano and enough speakers to sound almost exactly like a real piano. There are a…

If I want to learn about this field and is somewhat familiar with only the classical approach to robotics, how should I get started?

Comparing gas vs electric seems incorrect. Should be comparing with induction instead. It is way more energy efficient (altho not necessarily more cost efficient). It produces no c…

I think people focus on protectionism because that is the traditional tool to fight things like foreign government's unfair subsidy practices. However, you cant just have protectio…

You're exactly right. I'm not asking for people to choose an inferior, pricier product. My thoughts is that China has the environment to have extreme competition which is leading t…

The progressive loss in consumer robotics company in the West to their Chinese counter parts has been disappointing. Much like drones, I suspect this is short sighted as the underl…
