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 cycle it. Took my daughter an afternoon.

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 the rails, which would make access easier? There is usually a generous margin beside the tracks.

This would also allow bigger panels to be used.

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 specific knot, I can do likewise. When I see a knot I recognise, I immediately know how to untie and re-tie it.

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 useful ones (especially for sailing)

* Clove hitch * Reef knot * Rolling hitch * Sheet bend

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 think that method is just as good (or bad) now as it was then.

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 unscientific observations!) greying typically begins in small areas, and often on the temples - not what I'd expect if caused by UV damage.

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 colour hair.

This is distinct from UV bleaching of the pigments in the hair.

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

(forgot to say I'm a former post-doc in Cell Biology)

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 only have single bands in any vertical lane. Any other bands show that the antibody is binding to other molecules.

The evidence of painting out the background is likely someone cleaning up other bands, where the antibody has bound to something other than the intended target. So, they are making out the antibody is better than it actually is.

Copy-pasted bands could be evidence of attempting to make a weak band look stronger, or even adding a band where one didn't exist - potentially the entire blot is fabricated.

Either way, like someone else said, this is like fabricating parts of a data sheet.

It doesn't excuse it, but like someone else said, scientists would never just trust an antibody they bought. They'd do their own tests. Labs will also share notes amongst each other, along the lines of "that antibody is bad, and also strongly binds XYZ. You should try this other one instead".

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 on weekends away from university. But when the political side began being pressed home more and more, it didn't sit well with my beliefs. Oh, and I met my now wife at that time, and didn't want to go disappearing off.

I ended up getting a PhD, doing academia for a couple of years, then moving in to industry. Some of it was fun, but the itch for proper adventure has never really left.

Now with a young daughter, we have mild family adventures, which are fun in their own right, but I do hope to have bigger adventures one day. Hopefully with my wife and daughter.

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 victims will find them.

One problem of the central cooldown is that it restricts the choice to be able to consume a package immediately, and some people might think that a problem.

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.

It's basically rabid conservation and tragedy of the commons writ large

How is this like "tragedy of the commons"?

Call it what you want, but a new life stage begins when we have serious responsibility for another human.

For some this comes early, like a "child" looking after a sick parent. For others (like me) this comes with having children.

My wife and I look back on the years we thought we were adults, because we lived on our own, had jobs and a cat, and chuckle to ourselves at how grown up we thought we were. This type of pretending to be an adult we call "adulting".

AWS Graviton and Microsoft Cobalt are arm-based.

if I had my way, job interviews would be exclusively audio only.

The problem just shifts. People with attractive voices would then have an advantage.

Something people often don't consider is the limited resources for doing science - time, money, etc.

The positive side to "bias" is intuition. This is where a bias ("I'm pretty sure it'll turn out to work like XYZ, so I'll do this experiment next, rather than getting bogged down in some other area.") massively shortcuts the amount of resources required to come to a scientific conclusion.

During my PhD, I made many such shortcuts, following my nose. If I didn't, and tried to do everything objectively, I'd still be optimising buffers, and other such things.

This would just be impractical. Nothing would ever get done. Too many potential experiments.

I buy 95% of my books second hand.

Secondhand book stores are also usually much more interesting than even good new stores.

Hopefully this wouldn't trigger autoimmune conditions.

The current state of terms and conditions is a clear failure of modern law.

No one is reading them, and it would be practically impossible to do so. Signing something you cannot practically read and understand clearly does not mean you actually accept them.

How can we wake people up to this absurdity? The law should exist to help society. When it is not helping, reform it.

This is what I find interesting - the response from most companies is "we will need fewer engineers because of AI", not "we can build more things because of AI".

What is driving companies to want to get rid of people, rather than do more? Is it just short-term investor-driven thinking?
