Staycation: day five.

Power still off, but outside is warming up. So now it’s a big ice rink outside with people playing bumper cars with the real things.

Not interested in partaking in that particular contact sport, and as a result I’m still not leaving the house even if the worry about frozen pipes is fading.

Instead trying to see how far I can get on the remaining merge window pulls on just battery power. Not very far I bet, but at least something.

PGE claims power back tonight. Of course, they did that yesterday too…

I met the original creator of #RTIC last week and what they're doing felt exciting. It is AFAIK the leading hard real-time solution for #Rust. I'm thinking that could something similar as #Jailhouse (a partitioning #hypervisor) be used to provide environment inside Linux to run workloads for something like RTIC . #rustlang

To this day even tho I've contributed #Intel #SGX support to the kernel, I don't know how to check the chain as an end user.

E.g. Signal claims to use Intel SGX. How do I verify that for my benefit? There really should be some sort of universal standard for attestation of SGX/TDX/SNP workloads.

I mean the workload itself can be with a proprietary technology but attestation should be standardised. With that we could perhaps have something like certification chain that goes from data center up to the web browser.

I think confidential computing today is broken because of this and for most somewhat useless, expect in the white papers speaking about military grade security and all that :-) The hardware is expensive, attestation is broken and even the terminology is broken. In normal crypto-terminology confidentiality does not guarantee integrity. Better name would be thus trusted computing and somewhat easier to put into your mouth too. I've hated that term since I first heard about it.

Another thing learned from local #rustlang meet up. There is one really useful sounding application for #Rust #embedded #USB stack: #firmware updates from web browser.

Some audio hardware uses #WebMIDI for this but this would widen the scope.

I'm not sure tho how the access would be provided to the device if the USB stack was compiled in wasm.

I learned over the weekend (I was at a local #rustlang meetup) that interrupt controller caps #riscv for competing with #ARM on real-time tasks. I also learned about #CLIC. Just wondering are there any other extensions making waves or is CLIC where the world is converging.

Great my money was literally stolen by #Amazon. No delivery and no refund because 30 days from delivery date was passed. A delivery date, of which I had no idea.

Would be nice if all package managers understood/aliased all common English verbs meaning "remove this package", because I can never remember if it's "remove", "erase", or "uninstall".

Right, someone reminded me yesterday that if you want rigid memory allocation scheme with heap, you can implement that with heapless crate. It will deliver allocation errors from pre-allocated heap per-allocation. For stuff that I might be doing with #Rust in user space that is good enough.

The de-facto response from Rust application for OOM is panic.

LOL, took year after grabbing #kilohearts #phaseplant to realize how take pitch tracking away from sampler: set harmonics to zero.

i like to phase plant as a replacement for one shot sample player because a sound can be mixed fully within a plugin which makes stuff easy to translate between projects and even #DAW's. you get nicely self-contained packages from #preset's. it provides measurable value over using stock plugins this way.

also one thing that is IMHO done better in any other synth i'm aware is preset management as you can easily configure additional directories, which can be e.g. in dropbox.

they've really thought of these boring file management aspects, which make it one of the best options for being a go-to synth.

cool my #riscv #keystone page table bootstrapping fixes for #cva6 are all merged to upstream. i debugged the issues over a month so nice to see that it was worth it. actually learning how #opensbi is implemented was in all cases definitely a good lesson to learn.

In 99,999% of cases it would be better if people would work out with existing and established open source communities to enable #Rust rather than making their "better" completely new version of any possible asset.

It is slow, tedious, complicated and sometimes even quite discouraging but if you are successful then you are also doing something of high measurable value. And by going through the long and hard path also the end users will get the governance of long-term support, which they IMHO deserve.

At least for me the end user is the king of the hill, not developers. We need to do the hard and nasty part.

We must never forget him and his contributions to our world forever - especially due to circumstances of injustice and the cause he became a martyr for.

Hmm... Does any of the standalone spreadsheets, such as #LibreOffice Calc, have equivalent to excellent #GoogleFinance function in Google Sheets? While at #Intel I used that to fill my tax reports and some of my co-workers used my "app" too but I've lost in since...

I'd rather redo it in standalone spreadsheet rather than browser...
