Well, if its unbreakable, then its either snake oil, or some variation on the one-time-pad (really depends on your definition of unbreakable).

But having read the article, this is definetly snake oil.

I have a number of things running in the background after booting, so here’s some numbers for you:

• Steam: 1.1GiB
• Firefox: 1 GiB
• Discord: 500-600 MiB
• SchildiChat (Matrix Client): 300 MiB
• KeePassXC: 180 MiB
• KDE’s System Monitor (which I am using to get these values): 140 MiB

In addition to that, there’s always a number of systems services, most of which use a negligible amount of memory, but here’s some I’m just picking out because I recognize what they do:

• plasmashell (KDE Plasma): 380 MiB
• kwin_wayland (also KDE Plasma): 70 MiB
• Syncthing: 80 MiB
• kdeconnectd: 30 MiB
• pipewire: 7.5 MiB (though there are some other processes associated with pipewire in addition to the main one)
• systemd-logind: 1.8 MiB
• systemd: 3.7 MiB
• cupsd: 2 MiB
• XWayland: 45 MiB
• Xorg: 40 MiB

Of course, these are just a snapshot of the systems state, and can only really give you a very rough idea of how much memory something might use at one point in time.

If you want to make your board game more complicated (probably not, but I like the idea, so I’m just throwing it in here), you could use it as an opportunity to teach virtual memory, segmentation, paging and internal vs external fragmentation. Maybe players get certain processes with memory requirements and have to fit them into their own main memory, and whoever can fit the most processes wins, or whoever cannot allocate memory for a new process looses. (I’m just writing down what’s coming out of my head, I don’t want to hijack your game idea, sorry.)

Yes, TinyCore-Core comes without a GUI (like the commenter above said, headless). When they say 28 MB RAM, that might even be overestimating it a bit. All of TinyCore-Core fits into just 17 MB. Of course that goes up if you need to install things, and I don’t know if it comes with an ssh-Server out-of-the-box. So for a proper server setup, 28 MB sounds pretty reasonable.

It blows my mind, that there is an entire Linux Distro, that fits into a modern processor’s cache. Who needs RAM anyways? (unfortunately, because of how cache works, we can’t actually use it without RAM)

If you run your services off of a homelab rack that dims the lights whenever you power it on

If you are in this situation, then you definetly should get some more power, or at least a UPS to make sure you don’t trip a breaker.

Ooh, very cool!

Are the two different pictures different wavelengths, or do you just have two seperate sensors? (I have no idea how this works, just a highschool level understanding of x-rays.)

That sounds pretty plausible, but I’m not sure.

The windows are only very slightly off center, inconsistent, and even the ones above the clock are as well (although the clock mechanism could extend both up and down).

But I also don’t have any better explanation.

What exactly makes this stand out as AI to you, and not just cosplay?

I can’t really find any of the telltale signs of AI. The books on the shelf all look fine, the mirror on the left edge looks perfect and I can’t find anything immediately noticeable on the costume.

If this is AI, I think it’s probably just the face, maybe the whole person, but certainly not the whole picture. But maybe I missed something, please let me know.

One thing I don’t like about the “master key” metaphor: I do lockpicking as a hobby. And locks built for a master key are easier to pick, because you can open them with two keys. It seems kinda obvious when you think about it. (You gotta be careful when picking mastered locks though, the master wafers can fall into the keyway and permanently destroy the lock.)

Depending on the language, there might exist an automated tool for generating those kinds of diagrams from code.

This one isn’t super well known, but for small projects I really like raylib, and raygui. It gets impractical for complex GUIs, but it does make it really easy to quickly start something from scratch.

I didn’t read more than what’s in OP’s post, but I think the reason the researchers can be so sure is because there are ways to mathematically prove that something cannot be calculated by an algorithm (this is related to how we can mathematically prove that some things cannot be proven).

One classic, simple example of this is the halting problem. It boils down to the fact that we can prove that there is no algorithm that can take any algorithm as an input and determine if that algorithm will finish (halt) after finite time.

Great write up.

As an amateur radio enthusiast, I’d like to add a bit of info to the radio related tips:

Wifi Motion & WhoFi

Depending on how it works, a radio jammer will almost definetly make you more identifiable and not less. Think of it a bit like being in a dark room. You can sorta see other people (or their silhouettes), but if someone turns on a torch, then you can definetly see the torch. (And any jammer with enough power to “blind” a wifi router at any more than a few meters away only works at 2.4 GHz, or is probably illegal.)

Radio

(or “locating recievers”) This is physically impossible.

Now locate a radio transmitter is easy. Ham radio clubs often do regular “fox hunts” where teams try to find a hidden transmitter as fast as possible.

However, most digital devices are transmitting and recieving at the same time, for wifi or bluetooth. Even if you’re just downloading something, you are still transmitting (I think that’s probably what you meant).

Another note on Wifi and Bluetooth

This might be common knowledge here, I think I’ve seen a post about it before. When wifi/bluetooth are on, your phone actively searches for nearby networks/devices to connect to. It specifically looks for known networks/devices, and fingerprinting your phone based on which networks/devices it knows is incredibly easy.

So, when you aren’t using it, turn wifi/bluetooth off.

Also a note on Gait Recognition

Walking funny usually doesn’t work.

(sorry, no sources here, I’m in a bit of a hurry)

Edited my comment to fix, thanks!

This is less of a source and more like a compilation of resources, but for anything spacecraft related I can always recommend Atomic Rockets. For this specifically, the page on Heat Radiators.

amateur radio was illegal to encrypt

Amateur radio is still illegal to encrypt (with some exceptions for controlling satelites), because private communication isn’t the point of amateur radio.

Besides, (in most countries) there are some topics that are illegal to talk over amateur radio about, mainly stuff like politics and religion. You’re also not allowed to offer telecommunication services (i.e. pass messages on for others). Enforcing those sorts of laws would be impossible with encryption.

But to answer your question: I think we probably wouldn’t have had an internet. Authoritarian regimes thrive on stability and maintaining the status quo, I think someone high up would have quickly decided that developing that sort of tech is too risky.
