The solar sail reflects light instead of absorbing it so you get to double dip on photon momentum.

And sure, you can steer with the laser I suppose, but with that kind of super weak deltaV, you’re not going to be exactly doing donuts in the solar system.

Even the massive solar sail only imparts a super small amount of force. It’s only useful because it does so for free over a long period of time with no air resistance.

You’d be better off using a conventional thruster to do whatever steering you needed to do before letting the sail take over. It’s not like you need to steer around any obstacles.

Sure, but it would be less efficient than a sail, and since the incoming radiation would impart inertia on the solar panels, you would still be limited on where you could steer.

I ditched my smartphone spring of 2023. Still use it on WiFi at home, but every time I leave the house, I only carry a fliphone.

Every time a stranger asks me about it, they say something like “I wish I could ditch my smartphone.” Like I get it. It’s not easy. I can’t even go to a baseball game unless my wife has our tickets on her phone. Paying for parking sometimes requires an app.

Yet apparently everyone hates this thing that they are now required to carry around.

How did we get here?

Ironically, it didn't break, but when I was on the road and needed a power drill to fix something, I didn't feel bad about dropping $500 on a new Milwaukee from Ace hardware.

Power tools. If you are not a professional and need to buy a tool (if you can't borrow one), buy the cheap one.

I used a $30 Ryobi drill for over a decade and it was fine.

(For the US market. They still make sedans for Europe)

One of the temporary fixes for the Chevy Bolt fires was to update the software to detect if the battery was about to go up and then honk the horn to warn everyone which I think is hilarious.

If you sidegrade to a Casio F-91W, there’s a fun open-source project called Sensor Watch that repolaces the PCB to bring some nice features.

My watch can now tell me sunrise/sunset times, run 6 different count down timers, and act as a full dice set for DnD.

Like half of the water in the US goes to grow plants to feed animals that we eat. Fuck those animals, I want that water.

Nuts in brownies. Fucking don’t.

I mean to paraphrase Brenan Lee Mulligan: “if you have magic that can teleport things instantly, giving the task of delivering letters to Earth’s slowest bird is animal cruelty.”

 
 

Per my previous post, I’m working on updating my server that’s running a J3455 Celeron with 16gigs of ram.

Goals:

  • Support at least six hard drives (currently have six drives in software RAID 6). Can move 7th main drive to nvme.
  • Be faster at transcoding video. This is primarily so I can use PhotoPrism for video clips. Real-time transcoding 4K 80mbps video down to something streamabke would be nice. Despite getting QuickSync to work on the Celeron, I can’t pull more than 20fps unless I drop the output to like 640x480. Current build has no PCIe x16 slot.
  • Energy efficiency. Trying to avoid a dedicated video card.
  • Support more RAM. Currently maxed at 16gb.
  • Price: around $500
  • Server-grade hardware would be nice, but I want newer versions of quicksync and can’t afford newer server hardware. Motherboard choice is selected primarily because of chipset, number of SATA ports, and I found one open box.

Hoping to move my main drive to the NVME and keep the other six drives as-is without needing a reinstall.

Thoughts?

 

Everyone knows the tale of Brand X getting bought out by some faceless global conglomerate and going to shit, but does the opposite ever happen?
