(not a Twitter user) I saw the post linked below Carmacks post and I had assumed it's a comment to his post!

Yes, the way twitter mixes top posting for quotes and bottom posting for replies (which shouldn't really be separate features in the first place) and top posting again for timelines is really confusing if you are not a frequent user.

n=1, I was on a jury about a hit and run with a gun where flock cameras across the area were used as supporting evidence that the shooter was the acused. It painted a picture of his flight after the accident in his car.

Lots of other evidence was provided along it too. The defendant also left his phone on which was more damning, but it definitely helped us, as jurors, arrive to the "without reasonable doubt" conclusion

That's awesome.

In the US, they are everywhere - apartment buildings, houses, business. Amazon's Ring might the most popular, but there are many vendors.

All of these are "Artist's Impressions". My best guess is they run a simulation based on the data from the spacecraft and then can pan the camera around as they see fit

From the page:

[Image Description: A model image of what our home galaxy, the Milky Way, might look like edge-on, against a pitch-black backdrop. The Milky Way’s disc appears in the centre of the image, as a thin, dark-brown line spanning from left to right, with the hint of a wave in it. The line appears to be etched into a thin glowing layer of silver sand, that makes it look as if it was drawn with a coloured pencil on coarse paper. The bulge of the galaxy sits like a glowing, see-through pearl in the shape of a sphere in the centre of this brown line.]

That's an AI produced accessibility description so I thought it seemed wrong. But more directly from the article text: This is a new artist’s impression of our galaxy, the Milky Way, based on data from ESA’s Gaia space telescope.

Is it AI produced (if so, do they communicate it somewhere?) or do you believe it is?

The face-on galaxy image is credited to Stefan Payne-Wardenaar (https://stefanpw.myportfolio.com/home), whose Twitter and Bluesky bios say, "I make astronomy visualizations in Blender."

"The best Milky Way map, by Gaia (edge-on)"

The "by Gaia" implies the opposite to me. Unless the "artist's impressions" are from someone named Gaia???

"This is a new artist’s impression of our galaxy, the Milky Way, based on data from ESA’s Gaia space telescope."

I'm sure you know of headlines vs details; when it comes down to it, space science relies on marketing to get some funding and interest in it, and using 100% accurate headlines is not good marketing.

Further down, they explain the measurement errors involved:

" If you buy the same product twice, how much will chemical levels vary?

When we bought two samples of the same product, plastic chemical levels differed on average by 59%, calculated as Relative Percent Difference (RPD).

To test whether completely identical samples would show different levels of chemicals, we sent about 10% of our products in triplicate. This means we sent three copies of the product from the same batch – with matching lot number and expiration date – bought at the same store on the same day. We found that the triplicate samples differed less – on average by 33%.

Our lab’s quality control methodology lists 20% RPD as an acceptable margin of measurement error for duplicate samples, meaning if you tested the exact same sample twice, you could see up to a 20% difference purely due to measurement noise. Taking that into account, the RPD for two samples of the same product (not necessarily from the same lot) ranges from 39-59%. For samples with the same lot number and expiration date, the RPD narrows to 13-33%.

Within-product variability appears high, possibly because we are dealing with very small chemical concentrations measured in nanograms."

Yep, I saw that section. To my interpretation, these average percents are so much smaller than the variation seen, that it's basically /not/ addressing the outlier variations.

Perhaps plots would be better/less alarming than easy-to-cherry-pick tables, but I'm not expert on conveying this sort of data either...

How does tailscale help with securely self-hosting from home? I have it setup to interface securely with my PCs across networks (like at my inlaws), but not sure how it helps if i were to expose something to the world.

Thanks!

That is absolutely fantastic. Instant mayhem! Thank you for this.

Thank you! Very helpful as a newbie coming in.

> ... I have finally finished my steam loco after 10 years I do like looking at it and driving it.

That sounds fascinating! Could you share some more about your project?

It's about 1/11 scale of the real one, so the next size up from what Blondiehacks is building, and a bit more complicated and detailed. But essentially the same thing, a steam loco that runs on coal & water and works just like the real thing in every respect. See https://i.imgur.com/GuHR2j6.jpg

It can haul me and about 8 or 10 other people. It's a pretty popular hobby - look for live steam on YouTube.

"Blondyhacks" on YouTube is currently in the process of build model steam locomotive. You might want to check that out.

Or one of their previous projects if you'd like to binge start-to-finish.

Thank you for sharing, those are awesome exercises.
