The reason the OOM killer never kicks in is because you actually never run into an OOM, or almost never. What usually happens is that in near-OOM conditions, the kernel starts reclaiming memory pages backed by file (sometimes called "t

Note that π, like practically any constant or number normally found in mathemathics is constructive and contains a finite amount of information. What the author consider unphysical are the non-constructive reals: unfathomable numbers that c

There's an interesting paper[1] that argues that real numbers aren't physical, for the precise reasons you stated. That is, only the subset of real numbers that contain a finite amount of information (like constructive real number

It just means "cutting out" in a medical context. I'd say the fact that you can cut out genitalia is very tangential. In molecular biology it refers to removing a sequence of genetic material, so it's quite appropriate f

Thanks for the explanation. Do you know if it would be possible to fully create an ifd.bin knowing the specs of the mainboard? Basically the opposite of `ifdtool --dump`. I'm surprised because it seems to contain some pretty secretive

Unless new progress has been made that I'm not aware of, you need at least another blob beside the ME firmware (me.bin) to build a full coreboot image on the X230: there's the "Intel flash descriptor" (ifd.bin). I'm

No, it doesn't in any significant quantity [1]. Besides, there are practically no high Z elements in a fusion plasma. That's because they emit bremsstrahlung radiation (power grows like Z²) and rapidly cool off the plasma. If the
