Agreed, one of my great pleasures during COVID when I had terrible insomnia and couldn't sleep was to cycle down to Billingsgate in the morning and eat one of the fantastic bacon and scallop rolls from the cafe in the market. Definitely going to miss the place.
I had honestly made my peace with it moving to Dagenham. It makes sense for the Farringdon area, it makes sense for transport links, it even makes sense for the traders, who mostly live out that way. To close the existing markets without building a new one is cultural vandalism.
Unlikely, dead dark stars being dark matter candidates is a theory known as MACHOs (massive compact halo objects)
If they exist we would expect to detect them as they pass between another star and earth creating a gravitational lens. You can estimate the number of these MACHOs by looking at a bunch of stars for a long period of time and counting the number of microlensing events you see.
A team did this in 2000 and found that while there were some events, there weren't enough to explain all of the dark matter around the Milky Way. https://arxiv.org/abs/astro-ph/0001272
Dark matter is probably a grouping of several phenomena like this. Should not discount MACHOs just because it doesn't explain all the dark matter observations. I think I remember reading in Carroll's Astrophysics Intro that MACHO's can explain about 10-20% of dark matter. Dark matter could be potentially be explained fully by multiple dark matter explanations, each adding to the overall phenomena.
Could also be some mix of some of the proposed answers, and possibly even things that haven't yet been considered. To contrast, sort of like performance improvements in new CPUs aren't any one single thing but a lot of little incremental improvements.
That's not how gravity works. The "kicks" from star death aren't shooting them to the outside of the galazy where they just park.
The "kicks" are just tranforming the galactic orbital path from the typical "visible star path" to a different set of paths. The objects still would pass through the visible layer at some point, so the lensing events would still occur.
You know, assuming the described calculated results are true.
When the remains form surely they contribute to microlensing. But after they out of the visible Galaxy boundary, they stop. And given the end up 2-3 times from the boundary, they spent the vast majority of the time there without contributing to lensing.
Now consider that according to the paper 30% is going to leave the Galaxy. Those after the initial travel will never contribute to anything.
In many cases the status page of a service is an unreliable indicator (e.g. AWS's) so I find HN / Twitter to be a much better signal that an incident that affects many people is happening.
Oh right, because they don’t want cross-site scripts to be able to see redirected URLs since they could contain secrets. I wish we could completely do away with cross-site scripts and just have nice things!
Yea, so instead it would just encourage more 3rd party libraries doing random things on your site. This is what happens in native. Instead of embedding an ad in an iframe and isolating its damage you embed your ad service's library in your code and it spies on way more activity than it ever could otherwise.
It's pretty funny that such an RPC framework as the browser exists that gives the end user a genuinely decent sandbox, yet all it receives is criticism for its flaws. People will then happily install a screen dimmer or "productivity" tool with superuser privileges from a completely untrusted source.
I would also be okay (ish) with explicitly isolated third-party code execution, like your example of an iframe to a different domain. I'm pretty sure that should already be the case with iframes, in fact (you obviously shouldn't be able to embed an iframe to facebook.com on your website and then use your website's JavaScript to inspect the DOM on that facebook.com iframe).

I actually have a bottle of this on the shelf next to me. It's by far my favourite vodka out of what I've tried, but it's hard to tell how much of that is placebo because I know it's also the most expensive.
