I already have problems following Proposition 1 where they introduce a different DNF with twice the clauses of the original CNF than claim that maximizing the satisfied clauses in …

Last time I read about that, the problem seemed to be buckling [1]. E.g. if you look at Euler's critical load [2] then the pressure that a slender column can withstand just depends…

I'd think that the distance limit for _terrestrial_ mobile networks comes from the guard interval of the OFDM modulation [1]. I.e. on longer distances the time-offset between diffe…

Yes, I can see the cabinet from my window, so maybe less than 100 meters cable. Inside big cities that seems to be the state-of-the-art. They must have placed a lot of cabinets in …

Right now the modem reports a (link layer) data rate of 98338000 bit/s. Wget tops out at 10.7 MB/s.

I'm currently on profile 17a, I pay for 100 Mbit (downstream), and get like 90 Mbit actual IP protocol bandwidth (wget tops out at 10.7 MB/s). But I think the ATM signalling that's…

> You can't get these speeds with even VDSL.. That's not quite true. At least in germany, VDSL2 with "supervectoring" profile 35b [1] is routinely used, advertised as 250 Mbit inte…

> Interestingly, videos don't seem to count? It must be a written description? Wondering the same myself. Googeling for this issue turns up this power-point [1] which seems to impl…

But you need to be aware of the downsides of becoming inadvertently over-reliant on GPS [1] [1] https://en.wikipedia.org/wiki/Death_by_GPS

> Why not just use Evil, the VIM emulation layer. To cite Xah [1]: "xah-fly-keys.el is a modal editing mode for emacs, like vi, but the design of key/command choice is based on com…

> Long love ergomacs! I recently stumbled over, and started using (and modifying) Xah's "xah-fly-keys" emacs bindings, which are a somewhat more radical implementation of the ideas…

My not very well-informed take on the situation is: Yes, Emacs seems to make a lot of progress in many directions. Latest git master does have elisp native compilation support (via…

> Also, the fact that it's not rewritable means that... > 1. Security bugs[2] will never be fixed[3], rendering the hardware unsafe to use over time. But on the other hand: securit…

I think this is called "green hydrogen" [1] which has application as an energy storage medium, but also more. Energy storage also does not imply, that that hydrogen needs to be tur…

I think the Linux desktop (at least when running under an xserver) does have an obscure keyboard-mouse function, see e.g. here [1]. This seems to be enabled by default when running…

What about: DjVu [1]? It's not very well known, but it's so elegant, and also efficient, especially for scanned files. [1] https://en.wikipedia.org/wiki/DjVu

I don't know anything about the details here, but with usual linear algebra stuff, bandwidth depends on the size of the kernel that fits into the local memory inside whatever IC yo…

Whether liquid or not, running the formula for kinetic energy of the counterweight, I'm getting something around 1 GJ (gigajoule) for a weight of 1 ton at 1500 m/s [1]. According t…

Scott Manley talked on youtube about the centrifugal force on the wheel being around 10 thousand g (in the full sized version). So how do you build something that touches a tunnel …

Yes, that's an intriguing idea. What I came up with was this: the launch arm has a second mass inside it, that will move (via centrifugal force) away from the center, in the same m…

You are right, it does not say anything about the Permanent Court of Arbitration's decision on the matter. I was more trying to make the point, that various court decisions related…

Interestingly, the United Nations Human Rights Office's has quite the opposite opinion regarding the Evron vs. Donziger case (the one in the US that lead to Donziger's house arrest…

Talking about international bodies, we should also consider the opinion of the United Nations Working Group on Arbitrary Dention, which is that "Noting all the above, the Working G…

The wikipedia page on Donziger [1] says that the main witness to those bribe accusations retracted his statement and gives [2] as a source for that retraction. It seems, that the U…
