jesse_m··on FairEmail: Open-source, privacy friendly email app for Android
I love this app. I really like how it shows you tracking images and stuff in the emails.
jesse_m··on Unauthorized Bread: Jailbreaking IoT toasters
Radicalized is in paperback on Amazon: https://www.amazon.com/Radicalized-Cory-Doctorow/dp/12502292...

It has unauthorized bread in it.

Also, he gets more of a cut if you buy from him and no DRM! win-win
jesse_m··on Verified seL4 on secure RISC-V processors
One thing that seL4 requires is an mmu in order to support the isolation claims. The intel me type cpu would need to have some of these features that micorcontrollers don't usually have.
jesse_m··on Verified seL4 on secure RISC-V processors
That's not necessarily true. There are VMM or hypervisor projects that utilize seL4 for x86 and ARM [1][2][3]. In this situation there isn't really one that is in "control". You could also have other threads or components that have higher privileges that can maybe do other monitoring or control activities.

For what it's worth, the current draft of the hypervisor extensions is available here: https://github.com/riscv/riscv-isa-manual/releases/download/... and is Chapter 5

It does say this: The hypervisor extension has been designed to be efficiently emulable on platforms that donot implement the extension, by running the hypervisor in S-mode and trapping into M-modefor hypervisor CSR accesses and to maintain shadow page tables. The majority of CSR accessesfor type-2 hypervisors are valid S-mode accesses so need not be trapped. Hypervisors can supportnested virtualization analogously.

jesse_m··on Technical reasons to choose FreeBSD over GNU/Linux
Is the ports system similar to Gentoo's portage/ebuild system? I can get sources, configure the build, or get binaries (for some things) pretty easy through it.

The QA with the build farm would be nice though.

jesse_m··on Things Markdown got wrong
I can't stand the invisible syntax like double trailing space.

I can't stand the invisible syntax like a double trailing space is some valid syntax.
jesse_m··on SeL4 Design Principles
I think one of the big things here is that the refinement proofs from the models for isolation, IPC fast path, capability access control, and scheduling to C source to binary are strongest when the kernel is built with a particular configuration on particular hardware. When all of these are satisfied and you are on a trusted platform, you have very very strong guarantees that what is modeled is what you get. But it's not like this is hidden. They have make it pretty clear what the verified platforms and configurations are[1].

You should take a look at the verification chain though[1]. It is fairly extensive. It's not like they proved just a small part of a system in a general way.

The RISC-V proof is very close to being completed too. Gernot talked at the RISC-V Summit 2019: https://www.youtube.com/watch?v=2IXBoVIUuVI

I believe this was the HACMS program. Data61 has some more information: https://ts.data61.csiro.au/projects/TS/SMACCM/

It may be worth mentioning that it isn't the kernel that rebooted the system but some monitoring thread.

jesse_m··on We're making an open-source $30 GPS/mesh radio, would like advice
I think he's talking to the serval mesh guy
jesse_m··on Donald Knuth was framed
I haven't heard of the leo editor. I have used org mode in Emacs for little things. I also came across a reimplmentation of the tangling functionality: https://github.com/thblt/org-babel-tangle.py
jesse_m··on Ask HN: What are the underrated newsletters you like reading?
The Embedded Muse http://www.ganssle.com/tem-subunsub.html

Jack Ganssle has some really good content he's written for other publications as well.

jesse_m··on JMAP: Modern Mail Standard
Looks like there are some open source mail server projects that support it: https://jmap.io/software.html
jesse_m··on Show HN: Git-subcopy lets you link files across repositories
Is this similar to Android repo tool?
jesse_m··on Monorepo or Multirepo? Role-Based Repositories
Also Google's repo tool. I like the idea of manifests and the commands it includes for creating feature branches across repos
jesse_m··on Candidates for Mozilla's IRC Successor
fwiw, the Embedded Rust Working Group moved to matrix: https://rust-embedded.github.io/blog/newsletter-18/

how will we express the scale of something now?
jesse_m··on Firefox 66.0 Aims to Reduce Online Annoyances
I thought that when only web extension plugins were allowed shortcut extensions no longer worked. I was using keysnail. I was following https://bugzilla.mozilla.org/show_bug.cgi?id=1215061 but didn't know if it had been resolved. Thanks I'll check that out

jesse_m··on Firefox 66.0 Aims to Reduce Online Annoyances
Does this mean that custom emacs/vim keybindings can work again?
jesse_m··on Venus – RISC-V Simulator
I do believe Western Digital is going to start shipping their products with RISC-V processors soon
jesse_m··on Firefox 64 Released
If you use duck duck go as your search engine I think you can use their bang search functionality
jesse_m··on The Programming Languages Zoo
Yeah I'm familiar with OCaml I wasnt sure if there was a language progression that was suggested to go through. I was actually interested in using Menhir more too.
jesse_m··on The Programming Languages Zoo
Is there one of these languages to start with? Or would you choose one that interests you and study that one? There seems like some great content but I don't see a clear place to start
jesse_m··on Ask HN: Where can I obtain Google Glass(-like) devices for development purposes?
I've been looking at this too bit where do you source the wave guides?

Thanks I was using Tusky but had the wrong format for the name

Ahh thank you. I had the format wrong there
