Apple will randomize your MAC when connecting to networks to maintain privacy. It’s a per-network setting that can be toggled off for your own private network if you want to.

Why is port 22 open? Is this on your router as well or just the server?

This is SSH, which you should pretty much never have open (to the internet! Local is fine) MC is by default 25565. You will have every bot on the internet probing that port.

You’re saying that data centers are replacing batteries constantly…just imagine the labor costs on that (and the down time), not even considering the material cost.

I’m the tech doing the battery replacements. The big boy UPSes are typically a 3-5 year replacement cycle. Something like this:

(I just picked the last one on my phone so not a great picture, they’re about the size of a small refrigerator)

On rack mount and desktop style UPSes 18-36 months isn’t unreasonable. Some of the smaller UPSes, like APC 750s, go through batteries even faster. My personal theory is that they just get and stay too hot.

There is typically zero downtime while servicing any of them, every critical system has redundant power supply and battery replacements usually don’t interrupt power output anyway. It would take multiple failures to cause any sort of significant downtime, and if it would, we just do them during scheduled downtime.

I’ve had exactly two dishwashers completely stop functioning in my entire life. Both were GE post Haier and within the last 6 years. Also had a Haier made GE microwave completely fail.

I replaced the microwave (and the matching stove) with Samsung and haven’t had one bit of trouble with either.

I thought I had just gotten a lemon, but three separate failures within a couple of years has really soured my opinion of them. I was a lot more worried about the Samsung appliances I bought, but they’ve been a dream.

Note: I am not recommending Samsung appliances, at all. I got an amazing deal and fully expected them to fail shortly after the warranty was up. I’ve had to repair several of my friends and family’s washers, dryers, and refrigerators. Samsung’s poor reputation is well earned, I just got lucky

It’s just easier to access and in a prettier box, covered in advertisements.

It is the only approved method for data destruction for the several banks and government agencies I support. If they trust it, I trust it.

I have checked a couple of times out of curiosity, after a secure erase the drive is as clean as if it had been DBANed. Sometimes things are standards because they work properly.

You buy a budget printer if you want to get into 3d printers. You buy a prusa if you want to get into 3d printing.

If you want to learn how everything works, you should get a kit. After it’s assembled you should be able to print nearly endlessly with nothing more than basic maintenance.

Hollywood is in St. Mary’s county. So is California (also a town, just about 15 minutes down the highway) for that matter.

It’s a public GitHub repo, there was nothing private about anything there
