As a man who used to have long hair for decades, this is just wrong. But also, usually using more than one shampoo + one conditioner is not going to make much difference.

Baby Shark. Because… it kinda looks like a shark? (Blue Mitsubishi Outlander Sport/ASX, depends on the country)

I made the jump recently, and although there are clear issues, I don’t see any reason to use windows as my primary gaming OS anymore. Some games still require some fiddling with proton versions, extra command line arguments, environment variables, etc. That is bad for the average user that just wants to click play and play. Also, I noticed that at least on my setup (alienware laptop with nvidia gpu), some games have clear performance issues compared to windows, mainly some UE games. But it’s not so bad to make me want to boot windows again.

And just some extra two cents: I’m still keeping a windows partition for those games that simply cannot run on linux, and it’s possible to keep your main library on the linux partition (I’m using btreefs) and use that same library on windows. You just have to install a driver on windows, and it works beautifully. Haven’t had any issues so far.

A laser, maybe, but definitely not LEDs. Vapor/gas lamps produce the narrowest frequency bands possible, because it comes from very well defined atomic transitions (Hz range). LEDs produce frequency bands with widths in the GHz/THz range, while semiconductor lasers can maybe reach KHz if they are really good. So, unfortunately, for this type of applications, vapor lamps would probably still be needed.

Edit: very good idea about using non-visible light!

It takes some fiddling, but it works, and is fantastic!
