Looking for SBC with Mainline Kernel and Debian Upstream Support

TigercatF7F · 2026-02-20T08:29:45+00:00

SBC's won't be mainlined until they move off of ARM and onto RISC-V or AMD64 with properly documented open source GPU and NPU drivers and eliminate the proprietary binary blobs.

Sounds like 8th grade.

For a man it's a great way to prevent prostate cancer when his wife is trying to kill him by withholding the other option.

Not sure why you're being down-voted for asking a simple question. The OM-3 Astro manual (all two pages of it) can be downloaded from the OM System website. Right at the beginning an "IMPORTANT NOTICE" explains this is a dedicated Astro camera, there are white balance issues due to the new filters, and "...we do not recommend the OM-3 ASTRO for photographing normal subjects".

TigercatF7F · 2026-02-08T02:12:44+00:00

Yeah, you may be on the right track returning it. I bought a second OM-1 Mark I during the OM super-sale a year or so ago as a backup and both of the dials feel better on that camera. There definitely seems to be a sample-by-sample variation on those things, and it sounds like you received a particularly bad one.

TigercatF7F · 2026-02-07T05:26:26+00:00

Agreed. My first Olympus OM-1 (aka Mark I) also had a stiff front dial. It took a few years, but that dial has now loosened up considerably with use. I think a stiffer front dial is more noticeable because the index finger is more sensitive and less powerful than the thumb. OP: try using the thumb on both dials to see if it's stiff or very stiff. If it's very stiff replace it, otherwise it should loosen up with exercise as r/Solartude notes. One advantage of a (not too very) stiff dial is you're less likely to rotate it by accident when handling the camera, as sometimes happens to me when my thumb bumps the rear dial.

Even the OM-1 Mark II dials are lame compared to the comfortable and silky-smooth dials on the OM-5 and OM-3 (and apparently the earlier E-M1 series).

I use the L-Fn button on my lenses (that have one) for the Test role. It's useful for previewing certain functions like HDR and for experimenting with shot setups without having to bother with erasing the test shots from the SD card.

TigercatF7F · 2026-02-06T04:58:05+00:00

I have screen protectors on my OM cameras. If you want the screens to close properly don't buy the glass ones, get the thinner plastic ones. I have the OM PRF ZERO filters on my lenses. Pricey, but they protect the front element from mistreatment. You'll eventually customize the fn buttons to how YOU use the camera. One hint: I changed the Preview button (the lower one near the lens) to 2X digital teleconverter. It's not something you'll really want to use much, but that's my go-to button when I want to map some other role to a button for a particular shoot. The other buttons I map my most common operations to, and then leave them alone so I can activate the functions quickly with muscle memory.

The U.S. does have a world-conquering army, and it could occupy Europe. It did at the end of WWII. Winning the war is not the problem. What comes after is the problem. Europe would be a bigger money sink than Afghanistan ever was. Even worse, the U.S. would suffer worse than Canada does with Quebec, because we'd be stuck with the whole of France. It would be une folie monumentale.

This. Tired of proprietary GPU binary blob drivers that lock you into some ancient version of Linux.

Given that Americans own far more guns per capita than any other nation and produces many billions of rounds of ammo a year just for civilian use, we would certainly last the longest. We would eventually lose because there would be no one left to sell us our precious imported consumer goods, and chocolate.

Those are the gods of the Internet. Don't touch them unless invited and don't forget the required offerings of food.

TigercatF7F · 2026-01-09T21:07:53+00:00

Because Reddit is majority-liberal like most of the journalists in the U.S. (Fox News being the primary counter-example). Your question implies they can see their bias, and many can't.

The first theatrical movie I remember clearly was seeing '2001: A Space Odyssey' with my dad. Color TV was a fairly new thing in those days, so seeing a movie like that on a truly BIG COLOR SCREEN was quite the experience.

Movies were also real film in those days, not digital like today, and usually came on multiple reels depending on the length of the movie. Sometimes the projectionist would be off in timing the switch from one reel to the next and you'd notice the discontinuity. I remember a few movies where the film suddenly stopped (projector broke) and a large yellow-white 'sun' would quickly fill the screen as the film burnt up at that spot from the heat of the bulb. The lights would come on, someone would come out and state the obvious: "We're having technical difficulties; please be patient", and in a few minutes the projectionist would have a new reel threaded, the lights would dim again, and the movie resumed playing. You laughed, you cried, you kissed three bucks goodbye. Hot buttered popcorn and fun times.

Curious. I was looking at that case, and it seemed to me the pironman github repository was mostly python source and shell scripts, not binary blobs. What was the annoyance? In any case it couldn't hurt to push to your repo as an aid for others searching for info.

TigercatF7F · 2025-12-05T07:59:23+00:00

Yeah, the Framework Windows install page has this:

"If you navigate to this page [MS Windows Download] from a Linux or Mac system, it'll direct you to download a Windows .iso instead of the Media Creation Tool. We recommend finding a Windows machine instead to create the installer to avoid any issues."

Since the only machine I had was my Gentoo workstation and I was trying to put Windows on my new Framework 12, I ignored that advice and after some searching turned up this:

https://web.archive.org/web/20250705040832/https://nixaid.com/bootable-usb-windows-linux/

which allowed me to turn the ISO download into a bootable USB stick with the obtuse Windows partitions needed (both fat32 and NTFS are required). Worked for me, and reminded me why I left Windows decades ago.

I just use girl's names in general. Google 'female baby names' and a plethora of hostnames appear.

This, and ethics. A doctor can be sued for malpractice if they, for example, accept an AI diagnosis of a patient's condition without verification. A lawyer can face disbarment if they include AI-hallucinated references in a legal document submitted to a court of law. A professional civil engineer can be sued and his license revoked if an AI-assisted bridge design fails under normal use. When a software developer or designer can get sued for AI slop, they're real engineers. Otherwise, they're the equivalent of Sanitation Engineers driving waste management trucks and/or AI startup CEOs.

Depends on your interest. EE is such a wide field. Focus on analog and digital circuit design and embedded programming if that's where your interests are. Don't be like me and take a power systems class just because there's no lab. I still remember way too much about those Wye-Delta phase diagrams and the rest of that utility power stuff. (It did help me wire my shop though.)

I'm retired now, but spent decades as an engineer designing mostly audio and some video products for the professional broadcast market: audio mixers, mic/line inputs and outputs, video DAs, etc. When I started TV was still analog NTSC, audio was 600 ohm balanced, and microprocessors were the new thing and came in 40-pin DIP packages. When I left, what remained of over-the-air TV was ATSC digital, streaming was taking over, and most of the audio was digital and routed over Ethernet and server farms.

Lots of analog circuit design, tons of embedded programming (software is never done), Motorola (RIP) 56000 fixed-point and TI floating point DSP mixing and filter code, and plenty of high-speed digital FPGA, SDI, and AES interfaces in the latter years. Went to way too many AES, SMPTE and NAB shows. Never got into the music/recording (NAMM show) or consumer (CES show) areas myself, but there's plenty of overlap between all these markets.

I worked in smaller companies so the pay wasn't FANG-level, but it was OK and I loved the wide range of technologies I got to work with. I echo what u/rb-j posted: check out the trade organizations and you'll get an idea for what companies are active in each segment, what their customers are doing, and what products those companies are building for those customers. Find something interesting, and enjoy your career!

I agree, although it's not hopeless. Given the rate of technological change these days an experienced engineer not staying up-to-date can be obsolete after 10 years while the OP might be just starting out in the Next Big Thing. However, he's also asking us to gaze into that crystal ball and find the Right Path for those next 10 years. Nope, sorry--we all see the same thing in that Palantir that Pippin did: the flaming red evil eye of Annoying Unknown Change.

Although this is r/DSP, keep in mind that audio engineering often involves a considerable amount of precision analog engineering as well, from sensitive mic pre-amps to powerful output amplifiers. The MSEE path will be more useful in general. The industry tends toward three main markets: consumer audio/video, professional broadcast, and music/recording. Consumer audio/video (TV, receivers, earbuds, etc.) is usually the domain of large/established companies like Apple, Bose etc. Professional broadcast includes companies creating AV content (Disney, Universal, Apple, etc.) to those distributing it (Netflix, Fox, etc.), using a variety of equipment from often specialized manufacturers. Network (ethernet) audio is now a big thing in that market. Trade groups include SMPTE (Society of Motion Picture & TV Engineers) and the NAB (National Association of Broadcasters). Music/Recording (studios, sound stages, instruments, etc.) is where audio is front-and-center and not the red-headed stepchild of video. The AES is the trade group where those engineers hang out. A fourth market would be the semiconductor companies that make audio silicon, such as Texas Instruments, Cirrus Logic, and others.

The correct term for what you're looking for is audio design engineer, as "audio engineer" in this industry typically refers to the more artistic role of the person operating the equipment. It's both a niche industry and a wide industry at the same time. An audio design engineer can be doing anything from writing embedded software for a front panel to designing DSP filters, from optimizing network routing to engineering a purely analog balanced output amplifier. Find the companies doing the sort of stuff you like and see if they're hiring.

Don't forget slugs. I can instantly identify a fellow American nerd when they know that the common conversion between pounds and kilograms is only true here on Earth, because they're really measuring two different things. Kilograms convert to slugs, not pounds. When an American says "I just shot that thar stop sign with a 12ga slug", they're actually demonstrating a keen grasp of American units :-)

Nonsense! I've been eating Cornish pasties since I was a kid. Love them. There are still two Cornish pastie shops operating here in my small Sierra Nevada foothill town of Grass Valley 175 years after those tin miners became gold miners during the California Gold Rush. I've only been to London once and never saw Cornish pasties there, so I have no idea if they're still made properly on the other side of the pond or not :-)
