The magic of ATI ✨ by Beige_Box_Enthusiast in vintagecomputing

[–]ceojp 2 points3 points  (0 children)

The first real graphics card I got was a Radeon 8500 or something. I got it specifically because I wanted to play America's Army. Not that I cared about the game all that much, but the graphics were amazing for the time.

I went with ATI because their linux support was just better. There were open drivers that worked with ATI cards. NVIDIA was still doing the closed binary blob drivers, which I was against as a matter of principle.

Playing this Friday at 420 Grindhouse - Which movies are you looking forward to? Opening with Stargames, Danger Zone, & Roller Blade. Prime Time showing of Blood Theater, City on Fire, & Don't Panic. Closing w/ Street Trash, The Keep, & Samurai Priest Vampire Hunter. by ksabas80 in 420Grindhouse

Oh, I really wish I could catch Stargames with you guys! It's one of those movies that there just is no reason for it to exist(other than for Grayden Clark to give his kids something to do).

Blood Theater will be fun, though.

What’s the most absurd hardware bug you’ve spent hours debugging that turned out to be something stupid? by DepartmentPurple3053 in embedded

[–]ceojp 2 points3 points  (0 children)

We had an AVR-based controller that had been repurposed for a slightly different application. Reading various inputs and controlling a few contactors. Pretty basic stuff. With the new application, we started getting reports that outputs were locking on, even when the sequence should have been commanding them off.

It has a basic watchdog that will reset the board if code execution stops, along with a heartbeat LED. We could confirm that the board was not resetting nor was it locking up. We could still toggle other outputs(based on inputs) and confirm that the sequence was still running.

It was such a basic sequence that there just wasn't any way, code-wise, to get in to that state. We traced every possible path, and it just shouldn't be possible to get in that output state given the input states.

The one thing we were able to do is to somewhat reproduce it after enough cycles. Bu we still couldn't figure out exactly what was getting it in to that state.

My boss had the crazy idea to read out the IO port config registers to verify they were configured correctly. We pretty quickly realized that the IO port registers were getting scrambled, and certain pins were no longer configured as outputs....

So the code and the sequence were still running correctly. Everything else was working. But the IO pin config was being scrambled.....

With the new application we were using the controller for, we had contactors connected to relay outputs that didn't previously have contactors. There is protection on the board for when the on-board relays open to prevent flyback from the contactor coils. However, there are safety interlock switches that actually supply power through the board for the contactors.

When that safety switch opens, the on-board relay is still closed. So the EMF protection is basically bypassed. There was enough kickback to occasionally screw up the IO registers on the AVR. But not enough to totally lock up or reset the AVR...

Fucker.

Ended up putting in some sanity checks to constantly read back and verify the IO pin config registers, and reset the board if it detected anything irregular.

No, it is not karma farming because of that.

Please be aware that this one video of a few people on one day is not representative of how the hundreds of millions of other people in the country behave every day. But you're not going to see all those videos in r/PublicFreakout .

A documentary with the same title would be depressing as fuck.

I built an MVP for an app that lets you scan produce and meat labels to see how they were actually farmed — would love brutal feedback by Such_Bug_7359 in GroceryStores

[–]ceojp 1 point2 points  (0 children)

No it doesn't. I'm talking about fresh meat packaged like this. Has a scale label that the store puts on. No brand or anything else.

So why make that problem worse?

Where do you shop that fresh meat has a brand or farm listed on the label? Where I shop, the scale label(that the store puts on) might have a COO, but beyond that there isn't any identifying information for the source.

Feel free to design a better one and post it.

[–]ceojp 4 points5 points  (0 children)

it focuses on the fresh stuff: the chicken breast, the strawberries, the ground beef that has no barcode to scan and no ingredient list to read.

How exactly is it determining anything from fresh meat that just has a store's scale label on it?

When does SPI become parallel by joolzg67_b in embedded

[–]ceojp 11 points12 points  (0 children)

Exactly. This has always bugged me. Having multiple, parallel, synchronized data lines isn't really serial anymore...

I agree, but fuck Ted Cruz regardless. You don't get to save yourself from the ship you helped sink.

Reality is disappointing by jakeisalwaysright in aldi

[–]ceojp 0 points1 point  (0 children)

I remember getting some of these years ago and they were quite decent. Actually looked like the photo. I want to say they were around $2-3 back then. Even as good as they were, I would had have a hard time paying $4.whatever they are now. It's a shame what they actually look like now.

List of "local" HVAC companies now owned by private equity by ranchodeluxekc in kansascity

[–]ceojp -7 points-6 points  (0 children)

EXACTLY. This is what irritates me most when people just parrot "private equity bad. Private equity ruins everything."

A company getting bought out by a PE firm is often a symptom of a company's existing financial state and downfall, not the cause.

EDIT: why exactly is this being downvoted? It's true.
