Lots of thinking, from someone apparently experienced with lab testing of anti-germ precautiuons. Zero testing.

Disappointing. He actually has the lab equipment to measure some of his theories about denatured proteins et al.

That egg was totally still edible, even if you pierce it for the cooking, it should be good for at least a few days. If you do it right, it can be weeks. In Germany you can buy cooked eggs in the super market and they are not refrigerated.
It addresses this in the article, but in countries that wash the bacterial layer off (like the US), they have to be refrigerated. This is to minimize salmonella contamination, EU deals with this by vaccinating hens against salmonella instead.
Even though it had a hole in the shell?

This article was weird, in that he went through the whole thing about how effective the layers are without also mentioning there was a hole through all of them other than the egg white (until the end).

Eggs really don't go bad quickly. It is common knowledge that due to different washing techniques it's safer in Europe than in North America to keep them unrefrigerated (raw), but let's just say a certain spouse of mine is pretty callous about that - a tray of 30 of them from Costco doesn't fit in the fridge right now so it sits around for a few days - and we've had exactly zero issues from all that. And hardboiled eggs don't spoil very fast either. If it had been sitting out for a week, I'd take a careful sniff at it before consuming but overnight is nothing. Edit all this assumes the raw eggs are going to be cooked, of course.
Yeah. When I moved from the UK (back) to the US I didn't know any better, and spent a year or two storing (washed, US) eggs on the counter or in the cupboard for weeks at a time. Never had a problem. I absolutely don't recommend doing that, and now conscientiously refrigerate my eggs. I do not, however, stress that much if an egg spends a bit of time at room temperature. It's maybe a risk? But it's not very much of one, in my opinion.
It would be safe overnight.

Any food can be poison including if it's sealed before a use-by, it's about a percentage which a overnight boiled egg would be lower than for the English word 'safe'.

The claim is cooked eggs don't last as long as normal eggs, what is interesting is what is the percentage/graph?

Boiled Easter eggs are a tradition. You don't hear about mass deaths around Easter unlike rice that's been left out at pre-wedding to wedding parties etc.

A little off topic, but: we who have chickens know that fresh eggs last for weeks if left unwashed.
Odd, I never refrigerate eggs.
there are people who look specificly for old eggs , that they then pickle, also there are a wide variety of cultural food practices, probably banned here in the west, that involve eggs and other foods bieng "aged" under certain conditions personaly, I cant eat factory eggs, something in the feed comes through in the eggs and makes me a bit queezy, farm eggs no problem, tried factory eggs a bunch of times blech!,every time.

I would love to learn about such things but there seems to be very little writing about topics like this compared to all kinds of software niches.

What's up with engineers working in industrial contexts? From where I'm standing it seems like they are one of the groups that talk the least about what they do. You hear a lot more about science, law, finance... Is it due to IP issues? Is it a cultural thing? Is it just that I'm not looking in the right places?

>Is it just that I'm not looking in the right places?

Pretty much. That and there's a lot more talk about software because there seems to be this "conventional wisdom" that software people need to blog.

Anyway...

A few off the top of my head. The other thing to think about is that while there are tons of software blogs, sites and forums, 99% of it is just regurgitating the same crap.
