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 other day debugging a problem and saw others see it too: http

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 this kind of code, every time you execute code it's alwa

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 increases exponentially to fix.

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 rendered at higher resolution than downsampled is usual

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://github.com/Shopify/ghostferry/bl

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 also some new roland models I haven't tried. Many dealer

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 combustion byproduct like gas (which your air quality meter m

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 protectionism without fostering competition and innovation in or

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 to better product. This is distinctly not the case

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 underlying technology eventually have national security concerns.

How would you even differentiate between retries? If you isolate it by domain, the website can redirect you 10 times, each collecting an attestation token. They could perform statistical analysis with cookies. Websites could even force logg

McDonalds app requires safetynet (effectively the same as this proposal) passing to access their app. Is that really required? If you put a capability in, people will use (and abuse) it.

I don't understand how a probabilistic holdbacks can be effective if you can requests for the attestation token multiple times. If the holdback percentage is 10%, the probability of getting no attestation for 10 calls in a row would be

You're right, but I think it's mostly semantic and depends on how you define "performant" or "fast". Real-time software is about being "fast enough", every time. After all, slow and fast is subjective

I found this to be hard-ish to get started as well. However, it turns out you just need to write your program to be performant, and know a few tricks to tune the OS and the scheduler. After looking on the internet and failing to find materi
