For a while now a Mozilla software project that's been an "unsung hero" has been DeepSpeech as their speech-to-text engine. Sadly, following the recent major layoffs at Mozilla and restructuring along with a shift to focusing more on their profitable activities, DeepSpeech for now has an uncertain future.
Google Finally Begins Their Open-Source Dance Around Linux User-Space Threading
Way back in 2013 there was a presentation at the Linux Plumbers Conference around Google's work on user-level threads and how they were working on new kernel functionality for using regular threads in a cooperative fashion and building various features off that. Fast forward to today, that functionality has been in use internally at Google for a range of services for latency-sensitive services and greater control over user-space scheduling while now finally in 2020 they are working towards open-sourcing that work.
Microsoft Has A Large Presence At This Year's X.Org Conference
Years ago if saying Microsoft would have multiple developers presenting at the annual X.Org Developers' Conference (XDC) as well as being a sponsor, you'd probably raise some laughs. But this year for XDC2020 Gdansk (albeit virtual due to COVID-19), Microsoft engineers gave not just one talk but three on the opening day.
