Yesterday I gave @fredy a shelving unit that was in my backyard and upon inspection, we noticed that there was a little smashed egg crusted onto the top shelf.

I had no idea how that had gotten there, so I went looking in my back yard this morning and found the source

@MLE_online @fredy That's kind of sad. We found a couple of smashed eggs under the cover of our trailer. Apparently a nest had been built on the yoke and the wind blowing the cover had pushed it off.

I don't know who the genius is at Nvidia who convinces these tech bros that their new "killer app" can only work on Nvidia GPUs but they are two for two (Crypto and AI). Can't wait for the third iteration of this game.

Alright, lots of heavy discussions today, so let's talk about something silly!

What is a movie that always makes you laugh?

Personal pick:

Anything Mel Brooks, but Robin Hood: Men in Tights, it's just funny every time I watch it.

ChuckMcManis,
@ChuckMcManis@chaos.social avatar

@RickiTarr "Date Night", just too much to relate to in that movie. Also "Galaxy Quest" which is the best Star Trek spoof ever. Finally "My Cousin Vinny" because who can't watch Melissa Torme say "Like you blend?"

You write safe Rust.

I disabled SIGSEGV in my C++.

We are not the same.

In all seriousness, I'd love if anyone had a better solution to this problem. But there doesn't seem to be any SFR bit I can set to make the STM32H7 flash IP not throw a bus fault on an ECC failure.

So if you ever have a bug in your firmware that writes to the same flash ECC block twice without erasing it, that flash block will become toxic and any future attempt to deref any address within it will segfault. Not good if you're trying to make a robust, log-structured data store (in which any bug or unexpected power cycle poisons the entire key-value store, segfaulting future reads).

Turning off faults when writing, or when doing CRC checks on read data, allows graceful degradation when things go wrong.

Still trying to figure out why the bootloader seems to be stepping on non-blank flash cells (it should be appending at the end), but at least it's not soft-bricking the board by throwing the bootloader into a fault handler before it reaches the DFU flow.

ChuckMcManis,
@ChuckMcManis@chaos.social avatar

@azonenberg @dok So, in a sense, it was working as intended and notifying you that the flash had been corrupted. 😉 At Netapp we had NVRAM that would hold the current checksums when we had a raid stripe "open" (it was being modified but had not yet been committed).

My partner has put over 800 miles on her new plug in hybrid, and she still has over half of the original tank of gas from the dealership.

PHEVs are seriously the best of both worlds if you're not ready to take the leap to a fully electric vehicle.

@kwf
Noting that a 10kW Solar panel setup would top up a car, but you'd need two or three powerwalls (or equivalents) to hold on to the energy between production and refueling. So call it $50K for "lifetime gas" 🙂 If you don't grid tie your gas station you don't need PG&E's permission, just the city/county for the big "shade structure" you're putting up in your back yard.

A friend of my parents gave them a whole box of pieces of glass for doing stained glass, and they don't want it, so I grabbed a few pieces and I am grinding them up in my rock tumbler to try an experiment for ceramics class.

The rock tumbler is pleasantly quiet when full of glass versus when it's full of rocks

@MLE_online That looks like a very nice tumbler! I have only had crappy tumblers which I apparently use wrong because they are both noisy and the motor stops working and smokes.

I started borrowing DVDs from my public library last year, and now, I cannot figure out how people tolerate watching movies with all the dang commercial interruptions on cable/satellite TV. 🤔

ChuckMcManis,

@ai6yr Yup. One of the things a network attached storage devices does well is be a repository for your video data. I've created personal archives of my purchased digital content when the industry supplied "digital code" for a digital copy to a service that ceased to exist stopped working. Not only no commercials but every month, they are still available.

A question for developers.

Has ChatGPT replaced Google (or other search engine) when you need to look up something about a development project, environment, etc.?

ChuckMcManis,

@davew No "no" vote? Is that "I rely on search"? because that is increasingly becoming the same as "I look first on ChatGPT"

There's an article in the local paper today about my city updating its municipal code to add some new things to its list of activities banned in public parks, like camping.

But the article also briefly mentions some other things that are also bafflingly banned in public parks here, like flying a kite or bringing your own BBQ.

The article gives no explanation for why these other activities were previously banned, and now I feel like I have to put on my reporter hat and start researching.

I am unsure if this is click bait (outrage baiting?) or is CNBC trying to make their wealthy readers feel good? 🤔

ChuckMcManis,
@ChuckMcManis@chaos.social avatar

@ai6yr I think it is a bit more subtle than this. If you don't "have" to work you can just sit on the couch and watch TV. But for most people that doesn't feel "productive." I advise people who are "failing" at retirement to do volunteer work. A lot of non-profits can give you things to do which are both productive and rewarding in ways other than a paycheck.

ChuckMcManis,
@ChuckMcManis@chaos.social avatar

@ai6yr Exactly. I know a lot of people who, through stock options usually, reached the level that their investments grew at a rate where they could pay themselves the equivalent of their old 'take home' pay after taxes. My favorite is a guy who bought a tug boat and drives around the Sound in WA rescuing rich people who have gotten into trouble with their yachts. 😃

Archivist/Photographer question: My Dad, who was a professional photographer for 50 years, has moved into a memory care facility. I'm trying to organize his catalog. For photographers with 1TB+ of photos, do you use a system? Archivists same question. I may build a sqlite application to identify images by keywords but flat file system isn't going to work. Could be by date? by subject? by something else? Storage is a 2TB NVME SSD in USB-3.0 adapter.

I'm continuing to suspect that the CPUC is deliberately making California Net Energy Metering as convoluted as possible to make sure consumers don't stand a chance.

ChuckMcManis,
@ChuckMcManis@chaos.social avatar

@kwf This is absolutely true. When I installed solar in 2003 on my roof the 'E1' plan was pure watts for watts and at true up time you paid $0.11/kWh for the net used energy (you didn't get anything back if you generated more than you used). My bill that year was $89.00 of which $54 was the $4.50/month meter reading fee). 1/2

ChuckMcManis,
@ChuckMcManis@chaos.social avatar

@kwf PG&E successfully convinced the PUC that this was "unfair" because they go no money for their costs of maintaining the transmission infrastructure. This started the process of 'buying' at one rate and 'selling' at a different rate. Today, the most cost effective solution is to completely disconnect from the electricity grid. Even when that denies California excess power you might generate. That makes me sad. 2/fin

I find it notable that when the police brutalize people, a significant number of people observing this will blame the actions of the police on someone else. It is almost like they believe that police officers have no agency of their own.

Maybe they just like to beat up on people and it doesn't matter to them if they are asked to do so by a University or an elected representative, they are there to inflict cruelty, period.

My combat bot, "Footloose" is coming together. I had a lot of problems with the shuffling mechanism due to the 3D printed cams deforming over time. Amazingly, I found a business that could laser cut an aluminum set for me with a 24 hour turnaround, and the locomotion is now much more stable. Weapon is working, (and fun to test!) Now I'm going to add a wedge in the front and figure out how to shave off about 20g overall to make weight. Almost there...

Drat. Kitchen sink has a leak now. I wonder if it's because they loosed everything up but did not remove it. Think I'll fix this one myself, because:
A. doesn't leak unless you fill the non-disposal side of the sink
B. It's just one seal (tightened the P-trap and no issues there now)
C. The plumber charges more per hour than my own hourly rate writing software (!).
D. I will learn plumbing just to avoid the annoyance of dealing with caustic/flakey/expensive plumbers, in this case (easy to avoid this leak - not use that sink until it's fixed). Non-pressurized side of the plumbing system.

Surgeon has a sink that leaks and calls the plumber, the plumber crawls under the cabinet and fixes it in 15 minutes and charges him $500. The surgeon says, "Gee, I'm a surgeon and even I don't make $2000/hr." and the plumber responds, "Yeah, I didn't make $2000/hr as a surgeon either."

Assembling the trigger crossbar board over lunch.

Not thrilled with the paste print quality, very inconsistent. the top left corner was way too thick as the board flexed during printing, the middle BGA skipped some pads, and the WLCSP in the bottom right was near perfect.

These big boards bend too much in my paste fixture, I need to find a way to prevent that before I do any more boards of this scale.

@azonenberg This is so freakin' next level dude. I salute you. I shared it with the best rework tech I know and she said, "I would have have sent it back to the engineer to respin the board!"
