Woke up today to the homeserver being unresponsive. Couldn't SSH, no video out when I connected a monitor, and even the reset button didn't do anything. Had to hold the power button to shut it down.

/var/log/syslog doesn't show anything interesting other than the issue happened at just after 4am. Log

Would something like this be a direct hardware failure? Like a power supply hiccup or something? It happening at 4am coincides with my electric car starting to charge, but the server is on a dedicated 20A circuit and behind a battery backup. I also don't see any power issues on my Sense monitor at that time though it has limited resolution.

Mainboard is a Supermicro H13SAE-MF and I'm using ECC RAM.

I've been running this hardware for over a year and never had this issue, but I'm running out of places to look.

Might be time to finally get IPMI working.

I've been researching micros for a new project. I've already got some prototype code running on an STM32F407 disco, but I thought I'd try finding a costed down option for the final design.

I was surprised to find that the STM32H725 is not only cheaper, but it can run at 550MHz, has twice the memory, and has more advanced peripherals. Even the power numbers are similar if you slow it down to 170MHz to match the STM32F4.

The only real knock I could find on the H7 is that its smallest package is 10x10 over 7x7 on the F4.

So what's the deal? Is the price based on the actual value of the chip or is there some legacy stuff priced in?

I've never worked with an M7 core. Any other caveats I should be worried about?

Here's the ad. Here's an article where the producers whine about the backlash because they did a lot of work or something.

I really didn't think I'd be able to find something wrong with every single shot, but it was actually pretty easy (though some are way worse than others).

• Family in car: Girl in the back has no headrest.
• Rear shot of car: Unprotected wrapped gifts on the roof while it's wet enough to warrant wipers. Presents aren't secured by anything. Presents somehow bounce up off the rear of the car when it's a hatchback.
• Guy on bakfiet (bike): pushes the right pedal straight down through the crank arm. Rear fork somehow bends like 45 degrees between the down tube and rear axle.
• Carolers: Despite the matching hats and jackets, dude in the front's song book is twice the size of everyone else's.
• Teddy bear: Teeth (gross). Woman on right wraps her hand around behind Teddy's head, but that hand becomes woman on the left's hand.
• Santa on sleigh: White car passes by in the background, but red car behind it somehow disappears. Maybe it somehow is driving on the sidewalk behind the parked car?
• Tree: Tree physically grows taller and larger when tie is cut. Fire in fireplace isn't moving. Guy's right arm briefly disappears. Actually, it looks like they might have manually spliced two takes here because there's a weird slice around the man's chest.
• Outside of the house: There's apparently already a Christmas tree behind the family that you can see through the window. Also, the space with the bookshelf in the previous shot doesn't exist here as the front door is right there.
• Sliding to a halt: The tracks in the snow left by the guy's hand and armpits make no sense.
• Snowfall: cyclist to the right has a reflection, person behind them doesn't. Cyclist randomly stops pedaling right at the end of the shot (maybe not, hard to tell).
• Ice rink: Dude's right leg briefly bends backwards before it becomes his left leg and his hood becomes his right hand. After he lands, his (new) right foot is either passing through the ice or really short. Also dude middle-right stops and reverses without moving his feet.
• Falling from roof: Lights move and stretch weird, also house has two different styles of bay window. Also, looks like it might be a townhouse in which case, why is only one entrance fenced?
• Tram: Everyone in the tram is facing the camera. Nobody's on their phone? There are a few frames where the door is 100% closed, but the woman's feet are still standing on the inside floor of the tram instead of dropping to the pavement.
• Dining table: So much going on. Is that some kind of hibachi grill/fondue set in the foreground? I'd be more concerned about that catching fire. Nobody is reacting to the fire appropriately. What the hell is even on fire? Is that like burger patties on a grill?
• Cookies: Why are there crumbs everywhere if these cookies were presumably put in as dough. Also what the hell kind of cookies are they? Are they supposed to be gingerbread heads?
• Grandparents: Gramps got a stump for a hand then grows fingers. WTF card game are they playing?
• Up-close faces: Not much to say about these unless they're supposed to be the old people from the previous shot, because they clearly aren't.
• Bicycle spray: Cars parked on the sidewalk. Car passes through bicycle parked on the right which is also parked in the street.
• Baking: Girl has no reaction to explosion. Lots going on in the background. Is that orange juice being stored on an open shelf? Wine/martini glasses hanging upside down from nothing? Dude's got some kind of industrial kitchen grade mixing device behind the girl and yet can't operate a Kitchen-Aid?
• Cat in tree: What the hell are the people in the background doing? They start to take cover immediately. Drone changes from four arms with rotors to some kind of square shape with rotors at each corner after it hits the tree. Not sure what the thing falling off the left side of the tree is supposed to be.
• Tree lighting: Guy in the background reacts before anything happens. Girl on the left reacts despite looking at the floor/being asleep? Design of the table to the left changes when the lights go out. I wonder if this is another splice job where they needed to go through manually to make the lights-out synchronized. Also, why is this man plugging this in in the middle of the room anyway?
• Outdoor shot: Road layout has issues. Cars are driving right by cars parked the wrong way. Lamp posts are in the street. There's a bizarre window jutting out of the roof across the street.
• McDonald's entrance shots: I could be convinced these are real. The guy is the same person from the tree explosion who was probably comped in, so maybe it's a real actor.
• Couple at McDonald's: The girl kind of mimes drinking her drink. Guy in the background is clearly holding a mug
• Carolers again: There's a weird fade with one of the building surfaces middle-left behind the carolers. This might be another manual comp (makes sense with the branding). Lamp behind them looks like a combination lamppost/sconce.

First time keeping saltwater fish. Started on the 11/22 using the recommended amount of Dr. Tim's and bio starter. Test kit was still in the mail, so didn't notice the ammonia was only at 0.5ppm until 12/1. Added more to get it up to 2ppm. Nitrate and nitrite were still at 0ppm.

I've added a small amount of bio maintain since then, but otherwise let it work its magic.

So a week and a half later, and I took the test in the pic above. There's definitely some change to nitrate/nitrite, but I could convince myself that ammonia is anywhere from 0.5ppm to 2ppm depending on lighting. Maybe I'm colorblind. It's especially hard to decipher through photos (which I just started taking today).

I'm hoping to get the fish by the 18th so I can have them ready for a Christmas surprise. I know patience is a virtue when it comes to fishless cycling, but am I screwed? I have another option to get pre-cycled filter material, but I was hoping to grow this on my own.

If it matters, I'm using the 10L kreisel from jellyfishart.com. Hoping to order the jellies on the 16th so they arrive by the 18th. They ship with a pre-cycled filter, but something about introducing all of that at the same time makes me nervous.

I know banned book lists are often enforced at the state level through public schools and movies aren't really a part of common curriculum, but is there a good list anywhere of films that the government might try to...say...remove from streaming?
