You can buy high (97-99) CRI LEDs for things like the film industry, where it really does matter. They are very expensive, but can pay for themselves with longer service life, and lower power draw for long term installations.

The CRI on regular LED bulbs was climbing for a long time, but it seems as though 90ish is “good enough” most of the time.

You can just issue new certificates one per year, and otherwise keep your personal root CA encrypted. If someone is into your system to the point they can get the key as you use it, there are bigger things to worry about than them impersonating your own services to you.

A lot of businesses use the last 4 digits separately for some purposes, which means that even if it’s salted, you are only getting 110,000 total options, which is trivial to run through.

Don’t joke about this, the college professors will hear you.

An immutable OS is useful for things like an alarm clock, where if you accidentally muted the sound system, you could oversleep. There’s an obvious downside if you’re someone that watches porn on your alarm clock computer, but sometimes compromises must be made.

He only believes in the first 22 words of the first amendment. If you want to speak about what he has done, or (far worse) gather with others that share your beliefs to speak extra loud… straight to jail.

In 2003 (or thereabouts) I was a paying user of an Apple music product. They deliberately broke the way that I used their product, then once someone found a workaround, they broke that, too.

I tried to be their customer, and they kicked me out for not using Windows or MacOS. Now I’m emotionally invested in not giving them any money, ever.

This and systemctl cat $unit are my favorites.

Yeah, but then you have to limit your fashion selection! Imagine restricting yourself to wearing a hat over some silly fear of death.

“You wouldn’t put on a tricorn hat, would you?”

I actually would, if I could find a nice one…

“…and leave your job to sail the seas?”

… That’s an option? I didn’t even consider-

“And you certainly wouldn’t drink rum, and fire cannons, and carry a saber and tell silly parrot related puns.”

Cost is obviously a big factor. Almost every printer can change to any nozzle size and layer height for just the cost of the nozzle. Print volume is a major limitation, depending on your use case. The filaments it can print will probably be the same across any relatively low cost printers, with the only significant change being direct drive vs. Bowden.

Bed leveling is huge, and makes probably the most difference in print quality on low cost printers these days. If there’s an easy way to tension the belts, that’s a plus. If there isn’t a power switch on the front (or even if there is), a emergency stop switch can be a help, like if the nozzle is running into the bed.

Maintenance varies from printer to printer, generally you’re aiming for tight but not too tight on any belts or rollers. If the pulleys on the motors aren’t preinstalled, use something like loctite blue to fix them in place better.

Also make sure if you plan to buy a printer that it’s got a decent amount of community around it. Running into the same problems with a bunch of other people is a big plus as a beginner, so popular printers are better.

Teaching Tech made a calibration guide website that I’ve had a lot of good experiences with.

Last time I tried freecad, the geometry solver was incorrect, so it would sometimes create two (or more) shapes from a fully constrained part. Since learning about openSCAD, I’ve seen no reason to give it another try.

I’m an extremely wealthy arabic numeral, and all my wealth is tied up in high quality French made cookware. If you pay shipping, I’ll deliver a truckload of cookware to your commercial warehouse facility, and you can keep one pallet as payment.

I accept Steam gift cards, Bitcoins, and pork belly futures.

My great uncle said he hoped for a quiet death.

A major factor is the window manager you use, and the settings of that window manager. I’m not up to speed with it, but I think this one is GNOME.

It depends on how much other people care about your data, and how much physical control you have over the devices. If you’re in “nation states would like to have it” territory, you should never have unencrypted data at rest, or on the wire. If you’re a regular home user and all your computer stuff is inside your own house, you’re probably fine. In between, there’s a lot of possibilities. Encryption is cheap.

An r320 is new enough that iDrac Express (two IPs on one interface) is available in the BIOS. The server needs a license for some features (like remotely attaching an ISO, and remote KVM), but not for the basics like controlling the power.

My favorite ML result was (details may be inaccurate, I’m trying to recall from memory) a model that analyzed scan images from MRI machines, that would have far more confidence of the problems it was detecting if the image was taken on a machine with an old manufacture date. The training data had very few negative results from older machines, so the assumption that an image taken on an old machine showed the issue fit the data.

There was speculation about why that would happen in the training data, but the pattern noticing machine sure noticed the pattern.

I don’t see her here posting a comment…

This year I made the switch on my gaming PC (Windows to Arch). Next year, my target is replacing my CNC controller system, probably using raspbian on a raspberry model 3. That will bring the Windows count down to 1, which is about as low as my household can go.
