Great article!
aside: I've never seen Stack Exchange used as a blogpost medium (which normally this kind of write-up would be) and I like it! It's still formatted as Q&A so people with the same question can find it, and what's more, suggest edits or write alternative solutions (as OP explicitly invites here) on equal footing themselves. A collaborative quest for the answer, but not anonymized like a wiki.
Very cool, I've never used a slide ruler but I can see how in logarithmic space, that 3.3/2 scaling factor simply becomes a distance you add.
Makes me want to get one now, because I like the concept of memorizing ratios rather than recipes (thanks to the popular eponymous book), and this seems more convenient (and satisfying) for non-trivial computations than getting my screen dirty or dictating it to an assistant.
That's still consumption of images rather than participation in reality. Kids can absolutely read in excess as a form of escapism. Books are easier than dealing with real life when someone else does the thinking and problem solving for you. Certainly great for learning in moderation but you won't learn interpersonal skills or how to ride a bike just by reading about them.
I find this site so fascinating, seeing how all the massive power lines are hooked up to far-away power plants and gradually have their voltage stepped down as they connect to consumers. All the undersea cables and pipelines I didn't know about.
I saw a nice presentation by Michael Cruickshank with an intelligence background that was using public geospatial data like what this is based on to model how climate change would affect power outages in an African city. In that case he was trying to figure out where all the power infrastructure was that would be affected in a flooding and then model network effects to figure out which parts of the city would end up being affected. Really interesting work.
Michael presented at the Berlin Geomob. His website has a more general overview of what he does: https://www.michaelcruickshank.me/recentwork. That does not seem to include a lot of detail on what he presented. Possibly because he is trying to be responsible here.
The security angle did come during the presentation. This is not the type of information that a lot of governments would want to make public but also something that could help them. You can mine a lot of intelligence from public data. And his approach of doing some kind of scenario modelling on top of the open data actually is interesting. That's something that can be used for good and for evil. And obviously something that a lot of intelligence agencies are probably already doing.
> You can mine a lot of intelligence from public data. And his approach of doing some kind of scenario modelling on top of the open data actually is interesting.
That’s sort of how it happens in the intelligence world. A bunch of analysts can look at open source data - news snippets, public data sets etc, but once they analyze it and distill to some conclusions it may become sensitive or classified.
> It’s a double edged sword - secrecy leads to accidental damage by fishermen & anchors, so generally you want your cables and pipes charted.
Yeah, and the other edge of the sword is on display in the Baltic Sea nowadays, where "fishermen" accidentally keep dragging their anchors for miles across the sea bottom, always somehow exactly where the communication cables are.
I have license for boat and use nautical maps. They show me a cable, but not the hierarchy of the infrastructure. I see a cable, but can’t evaluate if half of town stays without electricity or only an island with dozen houses if I damage it.
However the available maps do not stop russian ships regularly dropping anchors on European infrastructure in Baltic see. Obviously charting them does not help. Maybe they should stay secret at the end.
You can hide the position of the cables from fishermen and the public. But if someone knows where they are, it is the KGB, I mean, FSB.
We should make information about infrastructure public.
There was a power outtage in Berlin, due to to an attack aginst a 'secret' cable bridge. If the map of cables would have been public, then the public may have had a chance to realize that having no backup cable is a bad idea for critical infrastructure.
There were backup cables. The bridge carried 5 cables, redundancy configuration would have been 3+2 afaik. But only for purposes of maintenance, not to protect against hostile action. For that, one should have taken care to not have all redundancies on the same bridge ;)
And in most environments, you cannot hide the location of those cables. Either they are visible directly, like all overhead power lines. No use in hiding those. And for the underground ones, you could try to hide them. But every backhoe operator will rightfully want a map of those anyways, so the information will come out in some way.
The only environment where hiding this kind of infrastructure would be possible is some state-does-everything soviet-like police state. Where comrade backhoe-operator wouldn't get a map, but he would get accompanied by a secret police supervisor who would tell him where to dig and where not to.
Would you feel comfortable making a decision on putting an anchor down on a cable if you knew it would only take out a few hundred houses worth of power.
I would imagine that any body that issues you a license should inform you to not anchor in proximity to cables, regardless of size / spec etc. if you put an anchor down on a charted cable, and the cable is where it should be, I think you’d be responsible for the cost of damage.
I anchor very carefully on the rocks or sandy seabed. I don’t anchor in seaweed areas and on pipes or cables. Additional attention from local newspaper is not desired.
In the EU all that data, including high res LiDAR data has to be made publicly available by the responsible authorities. also high res aerial imagery which with the lidar together you can use to build a 3D model of the surface and ground of military buildings/area in blender, because even that in many cases is not excluded or censored. It’s already used for “criminal activities” by metal detectorists and grave robbers a lot haha but it shouldn’t be too hard for foreign intelligence to render some maps for egoshooters from them to train their soldiers for missions in specific locations
Me too. I particularly recommend looking at the wind farms East of the UK and North of the Northern coast of Europe, and their connections back to land by power lines. Not something you think about when you imagine those seas looking at a regular map.
> most vegetables and legumes are missing necessary amino acids
In practice, there's no evidence of amino acid deficiency in vegans/vegetarians except ones that restrict even further (potato diet, fruitarians, etc)
https://pmc.ncbi.nlm.nih.gov/articles/PMC6893534/
Besides the ever-popular soybean being a complete protein, if you have normal variety in your diet, it's just not something you have to worry about.
>In practice, there's no evidence of amino acid deficiency in vegans/vegetarians
That is not what your linked article says. It says there is not evidence of protein deficiency, and the deficiency of amino acids is overstated. Not that there is no deficiency.
And vegan/vegetarian health is really a 2nd order variable here. Vegans and vegetarians could have massive amino acid surpluses and it remains a fact that vegetable proteins lack useful amino acids that meat has. Maybe the vegetarians are eating lots of eggs. Maybe they are taking lots of supplements. Maybe they are actually eating meat despite calling themselves vegans and vegetarians. It doesn't matter. There really is no disputing the fact about the composition of meat/vegetable protein.
> a fact that vegetable proteins lack useful amino acids that meat has.
This isn't a problem since you only need nine essential amino acids and they are present in adequate quantity in various vegetables and shrooms. The others are synthesized by ones body.
Only if those vegetables or shrooms were grown in natural sunlight (no greenhouse plastic/glass involved) and in a soil with abundant minerals, macronutrients, and high brix value.
Yeah thin clients [0] make a lot of sense with this kind of workflow. If you only really need text, living in the terminal and browser, it might make sense to use eink for eye comfiness and outdoor readability, something like this hack: https://maxogden.com/kindleberry-wireless. Or one of those eink android tablets.
Has the refresh rate on eink devices reached like 30-60fps?
It definitely looks cool and I might give it a try, but I do love my dark mode and color syntax. My understanding is that color on eink is pretty limited. It also isn't worth it to me if I'm going to be spending $500+ on a "monitor". But I'd definitely love if things moved in that direction.
Honestly if Apple wasn't so insistent on making the iPad not a general purpose computer I'd use that as my thin client.
They are still not great for high refresh rate, but I have a boox note air4C that can do fast-enough for video. It gets some ghosting (although it should be minimal for typing as you are fully changing from white to $color, backspaces might be a problem though). You will need a full refresh when scrolling but that is fast enough.
It's more like locking humans up in the matrix. Note lines like "preventing it from leaving the apparatus" in the build guide. Would an ordinary gamer be restricted from exiting such a contraption?
