Corps put value on TCO, repairability, sturdiness, LTS... Not on looks and image.
obarthelemy commented on Ask HN: Does having a betting/gambling company in your CV hurt your career?    · Posted by u/suddengunter

I used to be involved in hiring for a consultancy. We didn't care for previous employers as long as they were legal, we cared about projects, technologies, challenges... Then again we were open-minded, we did work for a quasi-pornsite and a very official gambling site.

My guess would be that some companies will object, but very few. Probably the same for which your religion, marital status, sexual orientation... will matter, so maybe not very desirable employers ?

That's not what the article nor the judgement say though...

It doesn't even need to be a startup: hearing aids are techically inferior to mid-range earbuds, yet cost more than 10x more. I'm guessing it's a certification+distribution issue, like for smartphones in the US. I've heard Bose has something in test though ?
obarthelemy commented on Ask HN: Android low latency audio in 2023    · Posted by u/techon

The initiative seems to have been abandoned. The results they managed to achieve were nowhere near adequate for live performance. The best results they got on the best possible hardware was about 14ms, which -- as you know -- isn't adequate for real-time audio performance.

My guess, based on experience with Rasberry Pi's: to do better than that, you need all drivers on the phone to have PREEMPT_RT patches, and contention with GPUs may be a deal-killer.

You might be interested in this approach:

PiPedal delivers sub-4ms latency (measured using loopback) without dropouts using a Raspberry PI that's accessed from a phone using Wi-Fi direct. (disclosure: I'm the author).

A few observations:

- An SMP_PREEMPT or SMP_RT Linux kernel is mandatory. Audio threads need to run with high real-time priority.

- Real-time and audio and GPUs don't seem to play well together. PiPedal delivers stable low-latency audio -- I think -- primarily because it runs headless.

- On Raspberry pi, GPUs have a dire effect on low-latency audio. Using non-GPU graphics drivers helps.

- SD card i/o has a moderately dire effect on low-latency audio. Ethernet and Wi-Fi i/o seems to have little to no effect on low-latency audio. Drive i/o to USB-connected storage devices is less of a problem with the caveat that the USB 2.0 ports share a bus, and USB 3.0 ports share a separate bus. The storage device should be on a USB 3.0 port, and the UBS audio device should be on a USB 2.0 port.

- All of this requires a Linux kernel later than ~5.15. Round about that time, the kernel ingested a significant portion of the PREEMPT_RT patches; and USB audio is essentially unusable prior to 5.10. This disqualifies a lot of ARM SOCs which still have 4.x kernels!

Contention with SD card i/o may just reflect the fact that full PREEMPT_RT patches haven't yet been propagated into mainline device drivers for that i/o path. Or that the patch set doesn't exist at all. A PREEMPT_RT kernel doesn't fix the problem.

Significantly, the Linux 5.1x audio and SMP_PREEMPT improvements post-date the Android real-time audio initiative. It might be time for Google to take another kick at the can. But in the meantime, real-time audio on Android remains borked.

Very interesting, thank you.
obarthelemy commented on Ask HN: Why is there no major push towards Android for Servers and Desktops?    · Posted by u/eternityforest

I'm very puzzled by the lack of Android desktops. Most users (not high-end users) would rather use the same OS and apps on all their devices, and Android is perfectly OK for content consumption, Office-type work, social and comms, light games...

There were a few very early attempts at Android laptops, but as for tablets (only worse), w/o any support from Google (Playstore category, guidelines...) those floundered.

I blame mostly ChromeOS, preferred by Google because it fixed the NIH issue and because why build one good ecosystem when you can build an OK one AND a bad one ? I'm still making "Android desktops" from TV boxes for the elderly around me. Android's support for standard webcams and other USB devices is a boon. It only really needs an LTS version, and some devices/apps guidelines and vetting. Not sexy enough for Googleheads, I guess ?
