Good on you for creating something fun, but vibing something up and then trying to charge for it, when anyone else could produce the same product for less, is poor taste.

Multiple people I know, and myself included, have experience failure of their USB-C port on their phones. I don't think they are really durable enough.

> You know those really annoying shower controls in fancy hotels when you need to adjust two separate knobs for the pressure and temperature separately? That's clunky. I like being…

Just buy your kid a good quality pedal bike [0], and take the pedals off. That way they can learn to use the brakes, and when you put the pedals on, they will quickly learn to cycl…

What are the advantages to putting them between the rails, where you need trains to stop running in order to access them? If it's about using wasted land, why not put them beside t…

I used to read it every week, and always liked the fact they stated their biases upfront - "This newspaper believes XYZ". Now I just live under a rock, and don't read any news.

Totally agree. Programming is not art. Does my company pay thousands of engineers to make art? I think not! We're paid to solve a problem that the customer has.

I used to use that a lot, but now would favour bowline, for ease of tying and untying. Less beginner-friendly, though.

Knowing common knots is not just useful because they are handy, but they also represent a common toolkit - when sailing with someone, if I see they tie a certain thing with a speci…

Depends what you're doing. My favourite knot is the bowline. Non-slip loop, very strong, easy to tie, easy to undo. Can be used for tying two ropes together, ropes to things. Other…

All my university (Oxford, UK) exams were in-person and had written. I had 6 exams over 6 days in 2012, in which my entire undergraduate degree was examined. It's not easy, but I t…

If hair greying was mostly caused by UV damage, I would expect that the pattern of greying would be even, and begin on the top of the head. In contrast (based on my own unscientifi…

When most people think of age-related hair greying (which you referenced in your original post), they think of the phenomenon whereby hair follicles stop producing pigments that co…

After a quick skim, that article seems to be talking about something other than typical age-related greying. More photobleaching.

I've not heard that grey hair is sun damage. Do you have any sources for that?

I really recommend reading "Ravens in Winter" by Bernd Heinrich https://jake-reich.co.uk/blog/17

Images like this show how specifically the antibody binds to the antigen. Generally, the ideal is to have very specific binding. As such, this type of image (Western blot) would on…

Travel, adventure, camaraderie, to name a few. At university I started down the path of joining the infantry as an officer. At first it was great fun - getting paid to go camping o…

My home wifi doesn't reach my side the bed from the router downstairs. Best way to prevent doomscrolling.

A central package cooldown is not really any different to individual cooldowns. The main reason for the cooldown is so security companies can find the issues, not that unwitting vi…

I have cut myself once, and only once with a sharp knife. I was about 7 years old, and my grandfather gave me a new (sharp!) Swiss army knife.
