US businesses only cry "free market" when they're trying to kill regulatory legislation.

IMO buying and selling are a matter of gambling on which way you think other people gamble.

I know what .rar and .gz are. If .lz is something similar, maybe dark matter is a compression artifact.

I'm sure that hopping on the AI bandwagon will fix everything.

The fact that it makes a big cloud around a galaxy or cluster rather than collapsing puts a lot of constraints on what it can do.

For more info, you'll have to go to someone who knows more about it than what I've read on science-news websites.

Dark energy is a real puzzle. As I understand it, it's too weak by a factor of 10^30 or 10^60 in comparison from what we should expect the known vacuum energy would cause. You see this mentioned very occasionally, but most treatments of DE that a layman runs across just ignore it in favor of wringing their hands over some issue that is trivial in comparison.

Some boffin cam up with that idea, but they rule it out because DM apparently doesn't interact with itself (very much) other than by gravity, so it can't clump up tight like a star or a planet or a living thing. (Something to do with shedding energy, IIRC.)

But it's a cool idea. If I were a novelist I'd run with it.

Or just require logins, and require a modest microtransaction of $1 to create a login, or explicit administrator approval. Longtime actual users and contributors will be exempt through the administrator provision, and bots are free to create $1 accounts (which are bannable for abuse) thus funding the project. New actual users probably woud not be bothered if the rationale is explained.
If it's really worth it for them to crawl endless random URLs until the sun burns out its fuel, make them pay for the privilege.

What happens if you slam the door? Cause all the electrics to go haywire?

Interesting also how he fantasizes about needing get someone else to do it for him.

I think this is what he daydreams about when he wanks.

Because the Democrat Party (tm) finally saw the writing on the wall and the biggest supporters told his crusty old ass that if he ran he would 100% guarantee a trump victory, and he ultimately withdrew at the 11th hour. The important part is: it did not stop him from TRYING.
Maybe you forget about the part where the party basically had to have a fake as fuck primary due to low confidence in him (normally it would just be assumed), and when he was finally convinced not to run they had to push Kamala in as a nominated candidate, ultimately doing an end run around the democratic process--nobody outside of super delegates voted for her in a primary. The Democrat Party (tm) does not embrace democracy.

The problem with this argument, from the shop's point of view, is that the UK is in the middle of a shoplifting epidemic. The policing resources simply aren't there to deal with small scale (or even flagrant and much larger scale) shoplifting. It now seems to be rare for police officers to attend reports of shoplifting at all. And so effectively shoplifting becomes legalised, which is obviously hurting the big chain stores financially and potentially devastating for smaller shops.

Shops are trying to find some way to respond to this to protect themselves. They typically tell staff, even security staff, not to get physical with shoplifters as they walk out, not least because the risk of something worse happening and the business becoming liable for it is significant. But then the shoplifters know this and some of them will just walk in and openly empty a shelf into a bag and walk out again without paying because they know no-one will try to stop them.

Shops also know that our court system is completely overwhelmed at the moment and there is little chance of bringing any successful civil action to recover damages from shoplifters who aren't even being arrested by the police and put through the criminal justice system.

So what do they have left? Basically, they're trying to spot the "usual suspects" and refuse them entry in the first place, which is a less risky proposition in terms of potential for physical violence and quite effective because a lot of shoplifting is done by the same people, or they're trying to make it more physically difficult to steal goods, for example by using locking systems or keeping high value items behind counters where customers can't just pick them up. But these systems aren't perfect, far from it, and what we're discussing here today is one of the significant problems.

Obviously this kind of technology can have very bad consequences, as we see here. I don't think it should be used if it's not highly reliable, given the potential harm done in cases where it gets something wrong. But I do have some sympathy with the shops who are looking for something -- anything -- to reduce the threat they're facing because the rule of law has failed in retail settings.

How 'bout if I buy now and pay after I die?

The technology that was highlighted in that movie originated around that time or a bit before. It goes by several names, but WAMI (wide area motion imagery) is kind of the generic term; it allows a forensic tech to rewind and track objects (people, vehicles) after an event. With AI and persistent vision, bottomless data center storage, it will allow everything / everyone to be tracked at all times. People don't know that this is already deployed over many large cities; essentially global hawk drones with high resolution hemispherical cameras constantly flying patterns, watching everything.

Nothing says low pressure social interaction like having a camera all up in your face while you try to eat drink and be merry, amirite?
