Back in college we used a Pi (not the latest gen because their code was out of date but whatever) and being a local with a car, I volunteered to get them for classmates who couldn't. This was back when you could really only buy them in

Oh yeah the branches too. It's made it super easy for me to ticket the issue, maybe the MR + branch in one click, and add it as a worktree. Honestly worktrees have saved my multitasking. I know Jira/Bitbucket do similar, but that&

Agreed. That's why the documentation is important. If the issue ticket says "I saw this but once. It took 2 days of reproducing and it could only be done if the moon was in a waning phase while 3 dogs bathed simultaneously" a

I've had great success with gitlab and it's issue + mr (they use "merge requests" which tbh feels more appropriate) tracker. I make an issue ticket, dump all symptoms, logs, relevant configs, whatever into it. Then I mak

This is the perfect spot to use a bitfield. You can tell it signed or unsigned, and the compiler will deal with it all and optimize. No bit ops to get wrong or maintain. Very readable and scalable.

That's an interesting write up and I hope the API change yields more useful data types. I'm not sure about the 28 byte size field, though. The way the rest of the code works it seems like a typo and sound be 8 bytes. I may dig int

Also the M7 is a superscaler. It's not mentioned often, but if the task allows it, you can use what's essentially 1.5x the execution units of the smaller cores. It's not a complete 2x, but I'm sure it helps.

As an FPGA developer: much agreed. We know exactly what's happening every clock cycle (or at least can), and often are able to have extremely deterministic computation. You can do this on micros, but anything with good performance will

My initial thought is you're getting escape sequences or other signals to trigger the bell/chime. I've never had it crash a terminal but I've never really used a macbook. A common one I'll see in gnome terminal is t

People deal with grief differently and that's ok, but for me it meant cutting out people who made fun of things that would've kept more of my family alive (I also stopped laughing at covidiot memes). If everyone masked & vaxxe

Early on he made fun of people who wore masks. I'd watched almost every video for years before that but as one of many impacted by others not taking covid seriously, I went cold turkey.

People poke fun that I prefer paper docs (notably boarding passes/tickets). However, last night I tried something new that involved starting a rental time and stopping it on my phone. That was the only way (despite it being a physical

What's the purpose though? You can put your own code on the app processor too. I don't know Android kernel dev but presumably with aosp you can do whatever the RV core does either in the A class core or using one of the many SoMs

Great for experimentation, but that's where it should end. If this is a cash grab or anyone is seriously considering buying it I think better products do or could exist. They'd be easier -> cheaper to design, maintain, source a

by Neywiny 2y ago
Yeah. As I'm sure you're aware, you can get Linux capable RV. I mean you can build mmu-less as well but there's plenty of I think it's M extension cores out there. This isn't that. This is a design that happens to u

This is like, barely risc-v. As far as I can tell, there's a risc-v management micro, an esp32 that I'm not easily finding a part number for so may as well be Tenscilica, and an app processor that's ARM based. I don't un

Because you've just changed what the password is. For example if your password is X, with hash Y, the server identifies Y as your password. Then I come along and steal Y. The server has no concept of X, so to the server you and I are e

I highly recommend Dark Waters (it's on Netflix in the US as of a few days ago). It covers a lot of PFAS history and politics in the US. It also finally convinced someone I know to stop thinking it's fine to eat teflon flakes and

There was a video, I don't remember who the host was but it was a STEM educator, who picked up a medieval sword at a museum (with permission) and remarked at how light it was. Since then I've internally thought about how unrealist

Huh. It never occurred to me that the word chipset was the descendent of a set of chips. That's nifty

So it looks like pretty much yes. I think the only real advantage I saw was the auth stuff. I guess this'll be a good tool in the toolbelt for when that time comes

I just needed simple values. It worked fine for me. I should've fuzzed it to check, but really I think all I needed was 1-2 decimal places.

I think recently I had to make my own because strtod was too large for my embedded system. I just wanted simple xx.yy type strings, so it was as easy as parsing 2 integers, convert, divide, add, done. I often wish these functions had more v

Unsure on funding, but this is a proof of concept. It'll show that the modeling, design practices, manufacturing, etc are working. The "meta" of the plane. For example, while as you point out the air frame of the final produc

I might recommend a slightly higher end micro with a mipi csi interface but otherwise agree. This is so much work to do what microcontrollers can do almost effortlessly.

I got offered a job (through some automated recruiting methods, I'm not that special) where the concept was to write SO answers with extremely tight style restrictions. I ended up turning it down because I disagreed with their style gu

I appreciate that the linked post is 9 years old. That's usually my problem with duplicates so I have to put in my post every possible duplicate and why it didn't work.

It's a 2-3x performance improvement according to don't benchmarks ( https://github.com/nopnop2002/esp-idf-benchmark ) but in general think it's more that espressif aren't trying to be the highest perf
