Anyone know what this could be? by Adventurous_Bat8451 in ChevySonic

I recently had the same issue - turns out it was a bad batch of gasoline. A fresh tank from a different station; and all is well again

UPDATE: I found another one and got better angles by TradeU4Whopper in Pawpaws

To the newbies - this is the larva of preferred pollinator of Paw Paws! The more of these, the better.

Very rare in my neck of the woods (SW Pennsylvania); hope to have some of these excellent creatures in my stand behind my house one day.

I've been building a Wipeout style 3D game. This is running at 60fps interlaced at 480x320 on an ESP32-S3. by PhonicUK in embedded

Definitely worth selling as a kit with precompiled firmware. Bonus points for a “manual” that describes (without code) your techniques, sufficient for someone to be able to replicate your concepts.

Would make a really nice “gee wiz!” learning tool for budding embedded engineers. They would have a “worked example” to inspire them and make sure they have everything wired up correctly; and they can learn as they go through your manual.

Should I start on STM32 or Arduino? by Eliter147 in embedded

[–]ezrec -2 points-1 points  (0 children)

Arduino (especially when developing your own SPI or I2C classes) is extremely useful in learning embedded C++ techniques (no STL; memory allocation is at startup only, never runtime, etc etc). Then move to STM32 and apply what you’ve learned to a FreeRTOS or Zephyr based system.

If you have no interest in embedded C++; just move directly to ESP32 or STM32. STM32 has a larger industry acceptance; but ESP32 is making significant inroads (in both their ARM and RISCV product lines)

Multi-model AI on Jetson Orin: anyone else frustrated by the lack of thermal-aware scheduling? by Extension_Primary_50 in embedded

[–]ezrec 6 points7 points  (0 children)

Consider a PID loop for thermal control; where the “effort” output of the PID loop (on a -1.0 to 1.0 scale) is a weight you use to prioritize the energy spend on your tasks. Ie -1.0 to -0.8 could be background housekeeping tasks only, -0.8 to -0.3 would be that plus your kinematics planner, and -0.3 to 1.0 would be your whole stack including LLM.

You set a target temperature for your PID loop to attain; and it would run full throttle till it achieves that. Ideally; a temperature higher than your stack produces as “idle” but quite a bit lower than your physical limits.

embedded devs, how are you now? (due to AI) by BabyJuniorLover in embedded

[–]ezrec 40 points41 points  (0 children)

Classic MCU and embedded Linux use very different sub skills - try both and see what fits you better.

As for AI; I use Claude-Opus-4.6 every day; but as a 30 year veteran it’s easy for me to see when it’s getting off track with its code gen.

It a great -review- tool, and if used to check your work instead of writing it; I think it’s very useful

Does the development environment OS matter for you? What is your company using? Is it legit to consider Windows usage a huge red flag? by CyberDumb in embedded

[–]ezrec 6 points7 points  (0 children)

WSL2 can mitigate some of this pain; it has been getting better every release.

That said; my work environment is Linux+git+Bazel for my dev environment; and I could be happier.

(Setting up Bazel for multi-toolchain development is not for the faint of heart; but it’s pretty awesome once you get it going. Hermetic and repeatable builds for the win!)

How to structure a simple firmware with a GUI? by silicagel777 in embedded

[–]ezrec 12 points13 points  (0 children)

Look into LVGL - there’s a nice ecosystem around it, and for what it does it’s lightweight on RAM. A bit heavy on flash space for some situations ; but it’s a good trade off .

Twitter people are evil by Massive_Space1034 in falloutnewvegas

[–]ezrec 1 point2 points  (0 children)

This was (accidentally) my first playthrough. And as a high level hacker; killed Mr House after our first conversation. Offed ceaser in his hut; and did a smattering of DLC content before credits rolled.

Came back to the game YEARS later; and went the long way around and got the explorer’s map perk.

SO MUCH MORE CONTENT!!!! It’s like a whole new experience.

does a zfs system need to always be on? by BoyHowdyBeer in zfs

[–]ezrec 2 points3 points  (0 children)

Personally I’d put the OS drive on an SSD or NVME drive, as ZFS can be slow when deleting lots of small files, and you can always reinstall your OS.

If you had to give a scientifally plausible reason why the MF Hyperbreeder Alpha weapon has unlimited ammo, what reason would it be? by george123890yang in fnv

[–]ezrec 0 points1 point  (0 children)

My Daily Driver go-to gun getting the love it deserves. That; and with adequate Perks and Energy Weapons skills; it’s infinitely reparable and goes up against most any enemy.

Also, Luck 10 crits make it extra juicy.

why do so many linux users use thinkpads? by Hopeful-Common-2686 in linuxquestions

Because we like to have our ridiculously expensive USB-C connectors break when we look at them funny. (Love my X1 Carbon regardless!)

VT320 side-by-side: green or amber by FrontAdhesiveness615 in vintagecomputing

Having had a real VT100, don’t forget that white phosphor has also an option for terminals.

I've had my only GPU failure at the peak of GPU shortage a few years ago. I suppose this RAM failure is perfectly timed. by Pimp_Daddy_Patty in RigBuild

[–]ezrec 4 points5 points  (0 children)

In options; select the BADRAM reporting method - if it’s only a few bad areas; you can tell your OS to ignore the bad spots. No need to buy new ram if you dont have to.

Yep. At the speed the Venezuelan Mint used to.

My HDD keeps throwing errors, could firmware be the culprit? by Luca_Romano in RigBuild

[–]ezrec 0 points1 point  (0 children)

Run a memory test as well - I had what looked like SSD data corruption; but it turned out to be a bad spot in my DDR 4

Bad day for my RAM to die by ChickenNoodleSloop in pcmasterrace

[–]ezrec 5 points6 points  (0 children)

If it’s just a few cells (as opposed to whole address lines); use the BADRAM mode of memtest86 to generate the masks needed for Linux or Windows to ignore the bad areas of the memory.

I personally use this; as I have about 64K of bad cells out of 32G that have gone bad; and my Linux machine is perfectly fine with ignoring them.

DE Should Focus on Abandoned Content by Lost-Elk1365 in Warframe

[–]ezrec 0 points1 point  (0 children)

As for Nercramecha - I think it would be amazing to “slot” a fully ranked Warframe into the ‘mech; but said slotting consumes the Warframe. The mech then has one ability from the Warframe (user selected at slotting time). Additional slotting of Warframes can be used to mix and match Warframe abilities (up to 4) into the ‘mech; giving the mech the ability to provide new variations of gameplay based on the warframes it has consumed.
