@cnxsoft @SipeedIO The last one I bought from you "with sigrok" required a hacked up, windows-only binary build where you never provided source or Mac builds and it wasn't accepted into the Sigrok tree. Fool me twice. Yes, I'm going to keep bitching every time I see a similar announcement.

Low-cost, Sigrok compatible USB 3.0 logic analyzer takes up to 16 channels cnx-software.com/2025/11/12/69-… @SipeedIO SLogic16U3 offers up to 3.2 Gbps bandwidth, 800MS/s for four channels, and supports over 150+ protocols thanks to integration with Sigrok/PulseView open-source software. It goes for $69 on AliExpress: s.click.aliexpress.com/e/_c3h0qIhl

@markitnl @LundukeJournal No, even more free. github.com/uutils/coreuti… (I saved you the search only because I already had it open.)

Ubuntu throwing out battle tested GNU Core Utils for untested, incomplete, Rust-developed clones. Debian forcing a new dependency on Rust, potentially breaking and “sunsetting” several Debian platform ports in the process. Both examples of forced Rust adoption — resulting in lost functionality and buggier software — mandated by employees of Canonical.

@atc1441 @DeLonghiUK That's a V3 core with "fixed" encryption. Harder to glitch, but there was a USENIX talk on overwriting $a0 to break out. Crazy that a coffe maker has three 32-bit cores w/ 2@240Mhz. :-/

Unexpected ESP32 in this 50€ @DeLonghiUK Coffee Machine 😄 Just wanted to find out how their Spinning Capsule Barcode reader works 1/n

@dangerousproto Not to tag along (OK, maybe a bit) once you HAVE NMEA, if you need to convert it, reduce it, filter it, interpolate it, slice it, dice it... oh, wait. Channeled too much inner Ron Popeil there. GPSBabel (free, open source) does LOTS of NMEA stuff. gpsbabel.org/htmldoc-develo…

New tutorial: Learn NMEA GPS modules with the Bus Pirate! Connect any GPS module via UART, decode NMEA sentences in real-time, and extract coordinates/satellite data. Includes a full teardown of common NMEA sentences. docs.buspirate.com/docs/devices/n…

@SipeedIO I hope that unlike the last one I bought from you, you actually release the source like you're required to do under GPL so that Mac users - that were promised builds - can at least build it themselves. Double shame that your code was so messy it couldn't be upstreamed.

New-Gen Logic Analyzer #SLogic16U3 launching soon! 40x40x10mm, USB3 5Gbps, 800M@4CH, 400M@8CH, 200M@16CH, Start at 59$! Sign up now to secure your early-bird deal before it’s gone: indiegogo.com/projects/--327…

@SipeedIO Unless it captures analog, only the top makes sense. You've still not released the source and/or Mac build of the last one I bought, though, in violation of GPL.

Which logo for logic analyzer SLogic16U3 is better? vote in next twitter~

@RueNahcMohr @splinedrive Because it's in my browser history ... git.kernel.org/pub/scm/linux/…

@RueNahcMohr @splinedrive I don't know the guy, but I know he spent more years at Rivos, SiFive, and Facebook than he did at Google. (He's been in the news before; I'm not a stalker.) That code wouldn't have flown at Google. He rushed, signed off on submitted garbage, and took a reputation hit.

The logic destroyer wouldn’t really be a destroyer if KianV wasn’t running the official mainline Linux kernel 6.17.0-rc1 — lol.

@soy1cookie @cbostona2liter @davepl1968 I know this because I'm on my second one... This is a spinal cord stimulator. It's just above the belt (note pelvis 'wings' just to the left of the hardware at L4-L5-S1) and has wires anchroed up in the thoracic area. The device "scrambles" pain signals from hip, leg, feet.

@cbostona2liter @davepl1968 Yikes! WTF is this? Lord, I’m taking more seriously my lumbago 😨

So you want to be a software engineer...

@rodrigo_p_a @davepl1968 That said, SimH, the PDP11 simulator, HAS been ported to esp32, so you could probably get 2BSD and maybe 3BSD going. I had port of UNIXv7 about 80% running on a RISC-V micro (GD32V103) that was WAY wimpier than an ESP32. That very context switch was where I lost interest.

@davepl1968 You never stop! Dave, as you are an expert and an excellent programmer, is it possible to port an older version of BSD to the ESP32?

ESP32 Spectrum Analyzer I wrote for the M5Stack connected to a Macbook for flashing.

@rodrigo_p_a @davepl1968 It would be unpleasant. ESP32 doesn't have a very robust MMU. Either everything is a global and process A can scribble on process B (intentionally or otherwise) or pswtch() randomizes and copies all writable segments every context switch. It would be as awful/useless as XENIX/86.

@StarFiveTech Ah, so it's a slower part - 1.25 instead of 1.5. That's the "Lite" Sorry, but that doesn't work. You chose the contractor to supply cores from and they didn't deliver, years after delivery date. Why make another part using a defective GPU they can't produce drivers for?

@robertlipe Regarding the JH7110S (up to 1.25 GHz) We regret that the GPU part cannot be directly resolved by our team at this stage, it is handled through Imagination.

@BruceHoult @splinedrive Howdy!

@robertlipe @splinedrive ::wave;:

I think a lot of accounts that left in a rush because of the X takeover and everything behind it might actually come back to X. I really miss so many accounts; they’ve all vanished into thin air. Yeah, it’s a shame. There’s a weird vibe right now. When I started being active here in 2021, there were some really awesome people around, and I miss them all. They’ve all bailed. Now it’s just AI garbage and, I don’t know, Grok back and forth. Ugh, all this crap. It’s not technical anymore. Everything’s just vibe coding nonsense. I’m seriously losing it here at this point.

@splinedrive ...and I just found one of the three on bsky. :-) Which I also check about once a month, but it is WAY less filled with rage-inducing garbage, so that number might go up. Hard to imagine coming back here as a poster.

@splinedrive People are over social media in general. The billionaires have all unmasked. I've not opened FB since 2022 midterms. I'm one. I might peek in here once a month. You're one of about three accounts left here I actually read and interact with. Back to RSS & Forums for nerd stuff.

@savourymarrow @MilkV_Official Then you also got a refund. (I did.) Sophgo, the chip maker, was found "accidentally" shipping chips to a restricted country, so they got kicked out of the fab and lost rights to the process. taipeitimes.com/News/biz/archi…

🚀 We’re back with the ultimate RISC-V MINI ITX - Milk-V Titan! Powered by UltraRISC UR-DP1000, the most powerful RISC-V CPU in production yet! Supports UEFI boot & plug-and-play high-end GPUs. PRE-ORDER Now! Get $50 off for just $5 on Arace.tech🔥#riscv #ultrarisc

@splinedrive At least two. Next Ubuntu will boot on exactly ZERO hardware that you can buy today. Z E R O. IBM/RedHat even admitted today they can't ship ANYTHING in under two years. Hobbyists and skill-builders will still buy dev boards at hobbyist $ levels, but they just froze the market.

In my opinion, someone has been incentivized to stall the RISC-V market for the next two years. As a result, consumers are reluctant to invest in current hardware, believing they need to wait for RVA23.

@splinedrive Credit where it's due: enhanced string delimiters are a (welcome) core language feature of C++11. C++17's string_view isn't really involved, though string_view IS awesome for finally delivering a non-owning range. Here's a plain ole char array.

I love how std::string_view in C++ lets me keep ASCII art in the source without escaping backslashes or quotes and best of all it runs on my KianV RISC-V Linux SoC with 49 days uptime

@splinedrive @SipeedIO I know you're firmly Team Linux, but I also know you're Team Open Source, and them not honoring GPL is the kind of thing you probably care about more than many people will. The earlier model, at least, was probably RISC-V BL618. They never published the firmware source, either.

@SipeedIO Channels?

🚀 #SLogic16U3 hits 750MHz at 1.5Gsps! It means frontend support upto 750MHz bandwidth (500MHz recommended w/ shielded cables). 💰 old-school USB3 LA is $300 for 1Gsps, but now SLogic16U3 is $69 for 1.5Gsps!
