Something seems to have changed in Twitter. Last Wednesday I got my first "you have notifications" email since 2018, which is a nice fix!

@mithro @enjoy_digital @cr1901 @LoveMHz @MakeMHz Agreed! I'm rather proud of that, for sure.

@suarezvictor @mithro @tannewt @whatnick Fomu has docs that were programmatically generated as well: rm.fomu.im I think mostly what you want is to pass `csr_svd` to the `Builder` to generate a SVD file: github.com/betrusted-io/b… You can also do litex.soc.doc.generate_docs(): github.com/betrusted-io/b…

I justreleased a first draft of filesystem support on Xous using PDDB as a backing! `std::fs::File` and friends now behave like you think they should on Xous. More information at xobs.io/experimental-r…

@josh_triplett @yaahc_ cc-rs works fine for RISC-V code, so I suspect that line in the comments is outdated. We build our version of compiler-builtins using C code: github.com/betrusted-io/c… I'm more wondering if the Rust builders have a RISC-V C compiler, so we could start upstreaming Xous support.

@yaahc_ I considered adding it upstream, but this comment made me hesitate: github.com/rust-lang/comp… Do the Rust distribution containers support RISC-V C compilation yet? If not, where should I look?

I've been working on a new embedded operating system called Xous. It's a memory protected microkernel. I just released a port of Rust's standard library for it. So nice to have an allocator again. xobs.io/porting-rust-s…

@woohuiren > okay, found out that viewqwest was leaking traffic on equinix IX and -nobody- is doing BGP filters. So technically isn't your fault. Still having routing issues :(

@DPMHackaday @GovTechSG We can't post pictures for one very mundane reason: they could be used to buy out the entire supply chain while a tender is ongoing.

I put together some of my thoughts on the @GovTechSG Trace Together Token at xobs.io/trace-together… -- tl;dr is that the hardware looks good, and we'll have to wait to see how the software looks

I was invited to review Singapore's #TraceTogether contact tracing token. Thoughts at bunniestudios.com/blog/?p=5820 My favorite insight: Singapore needs a token to serve two groups: the underprivileged, and iPhone users. Both don't own a phone, but for different reasons. @GovTechSG

@jim_mussared The Token's protocol is different, and the app will be updated to be compatible with both protocols. The Token relies exclusively on broadcast beacons rather than using a Gatt server. In that sense, it's closer in spirit to the Exposure Notification Protocol.

I got invited to the GovTech offices yesterday to take a look at the TraceTogether Token they developed. It's a sound approach they're taking. It was great to meet Minister Vivian Balakrishnan and hear some of the reasoning behind the Trace Together decisions.
