Hardly effective. Dongles are still allowed.

Especially "Is a smartphone detected?".

The past 3 routers I used had a random number sequence 20 or so number long on a sticker on the back. That sequence was the initial key and after a physical reset that will be the key again.

I always rather like "Secret" and "Above your paygrade" as multiple user passwords but "I forgot" would be a cool one too.
Now I just have to go back to a place where multiple user passwords are a thing again.

Vlad Tepes had similar ideas.

I haven't got an advice on what to buy. I do have an advice on what not to buy.
Don't trust a Trust
I have one. It is too slow. If I use it as an UPS and pull the wall plug the computer first shuts down due to power loss and then the UPS comes up and I can immediately restart my PC without putting the plug back in the wall.
It drops the power long enough to kill the PC. How can they not have detected that during testing?
It is useful for some other use cases, but not as an UPS. Just as an easy 240V power supply.

If driving over the ocean isn't going to stop him the Darién Gap will do nothing because then you can simply drive over the Caribbean sea and avoid that swamp all together.

Obligatory XKCD

I see a third option. If he can change the application maybe he can split the UI and the heavy lifting. Or maybe the application already has that option. The responsiveness of the local UI and the brute force of having the heavy lifting on a company owned cloud.
If the load gets to big maybe some of the heavy lifting can be shifted to overnight work. You know, just like Pixar does (or used to do).

Not all work can be done from home.

In some hyperfocussing modes my memory is almost output only. In those modes I can get loads done. It also means that I barely notice the passage of time because nothing new is stored in my memory.
I can forget to sleep in such a mode and only fall out of it because I get really hungry. Really as in: first I need some sugar so I don't pass out before I get some real food.

I really had to learn to comment well in such modes because it also means I can't really remember why I made choices.

Assuming there are no down sides I see no issue in using the placebo effect to get more energy.

The Sansa Clip is similarly sized as the iPod Shuffle. It has a micro SD card slot and later firmware updates allow FLAC and OGG.
It is a great player that survived my abuse for years, with only a silicone skin over it.
I have no direct experience on the successor Sansa Clip + but I would assume that it is similarly awesome.

Yep, but I prefer paying $2500 to iRiver over paying $1200 to Sony.

Not that I would buy either. They are a tad out of my price range and I can't see Spotify support in the list.

The mass difference between an entangled cat and a non entangled cat is the mass of the tread it got entangled in.
