What a blast from the past!!! I worked on that ship for 4.5 months back in 2003 when it was the MSY Windsurf. Played the piano in the Lounge. Thanks for the smiles my friend!!! :)

Nah man. You’re good. Just trying to explain and be helpful.

Motivations behind actions matter. Reducing trade with the US may have several justifications. Among these are to “balance a trade deficit” and “to isolate America financially”.

So, while the actions taken to reduce trade with the US may be the same for both justifications, there is a distinction to be made as to the justification for said actions.

What gets me about this photo is how fundamentally unserious the whole scene appears. The body language of nearly everyone, the lack of focus, the shabbiness of it all… just embarrassing. I’ve seen high school clubs looking more competent and serious.

I know this is just an aesthetics thing, but it gets to me. 🤷

Believe it or not, it’s a Sobey’s, so big chain. I was pleasantly surprised that it happened so quickly. I don’t know if my local store is representative of the chain though.

At my grocery store in Canada each Canadian product has a Canadian Flag next to each shelf price sticker. Makes it easy to know what to grab.

And that the USA exists in 4 years. Not saying it won’t, but the chances are disturbingly higher than 0%.

This dude most certainly does not abide.

Like, most of the time I do.

Just not in this particular instance.

Nice pic. I’m a little jealous that you’ve been able to see it yourself, but mostly glad to know some people are getting the chance and taking the opportunity. Cheers! 😀

If you have binoculars you should try using them. It’s not so much about the magnification, but rather the amount of light collected. Basically, the diameter of the objective lens is bigger than your own eyeball lenses/irises, so therefore more light is collected and projected to your retina while using binoculars.

I’m in western Canada right now and have so far not had the right conditions to see it myself. I’m hoping that might change in the next day or two.

I’m not a geologist but I’ve read up on it a fair bit.

This Mars photo appears to be sandstone.

On earth sandstone is usually associated with ancient rivers, lake shores, and sea shores. But also sand dune fields.

The thing with sandstone though, is it’s not just sand. Rather, it’s sand plus time plus pressure plus cementation.

Now, the time part is obvious. What’s sandstone now was sand a long ass time ago (usually).

Pressure? That’s a little harder to understand for me here. Has mars ever had tectonic stuff going on to bury it (and hence have pressure applied), followed by erosion and uplift? Or am I incorrect and pressure is not a necessary condition? Maybe sandstone without pressure is a thing it’s just weaker and/or less dense? Maybe layers of volcanic basalt or something could have a similar effect? I don’t know and would love to have someone more knowledgeable fill this part out.

Cementation? This part, I’m nearly certain, REQUIRES water. On earth anyway, this happens when ground water absorbs chemicals from other rock/stuff (for example carbonates from sea shells, but there’s lots of other chemicals that can do this), then flows through the beds of buried sand, and some of those chemicals are deposited along with magical chemistry stuff happening, and your sand becomes sand stone.

So I don’t 100% know that the short answer to your question is “yes”, but I’m leaning towards a solid “yeah, probably, but I’m not a real geologist and Mars isn’t a real Earth so I dunno”.

Depending on your threat model you’re almost certainly fine.

I abide.

I got 2.7k on a post, but I just got lucky.

I can try to explain, but there are people who know much more about this stuff than I do, so hopefully someone more knowledgeable steps in to check my work.

What does ‘random’ or ‘noise’ mean? In this context, random means that any given bit of information is equally as likely to be a 1 or a 0. Noise means a collection of information that is either random or unimportant/non-useful.

So, you say “Compression saves on redundant data”. Well, if we think that through, and consider the definitions I’ve given above, we will reason that ‘random noise’ either doesn’t have redundant information (due to the randomness), or that much of the information is not useful (due to its characteristic as noise).

I think that’s what the person is describing. Does that help?

I’m not an Information Theory guy, but I am aware that, regardless of how clever one might hope to be, there is a theoretical limit on how compressed any given set of information could possibly be; and this is particularly true for the lossless compression demanded by this challenge.

Quote from the article:

The skepticism is well-founded, said Karl Martin, chief technology officer of data science company Integrate.ai. Martin’s PhD thesis at the University of Toronto focused on data compression and security.

Neuralink’s brainwave signals are compressible at ratios of around 2 to 1 and up to 7 to 1, he said in an email. But 200 to 1 “is far beyond what we expect to be the fundamental limit of possibility.”

If you’re a programmer, or think you might want to be one, I highly recommend this channel. He’s a savant at all sorts of low level things, quite funny and entertaining, and does a fantastic job of explaining what’s going on.

It’s not just a fat or muscle thing. Those both contribute of course; fat insulates and muscle produces more heat. But the real player is the surface area to volume ratio.

A bigger person has a lot more volume than they have a bigger surface area, and since heat is lost through the skin this has a major impact.

I agree that, if the detection is accurate and correct, it could be produced through non-biological processes, but, on earth, the molecule in question is known to be produced solely by biological processes. So when you say “easily”, I must disagree.

This is very preliminary data, and we shouldn’t get overexcited about the possible implications of this discovery, but I think it’s fascinating.
