You realize that many of his novels are about how these laws fail?

Can you prove this? Or link a proof?

Then put 23456789 at the start. Doesn't contain 22 then but all digits in base 10.

In German it's called "Der Göffel" a mix of "Der Löffel" (spoon) and "Die Gabel" (fork). So it's masculine from the Löffel part.

It's funny how the word mix is backwards in German/English. English has fork at the end of the word and German spoon.

Correct me if I'm wrong but the Linux Kernel itself does not enforce a directory structure at all. It's the user space (including the init ram image) that mounts the system directories wherever they want them.

Edit: Besides inside mountable system filesystems like sysfs or /proc etc

That is called racing to sleep iirc and is a valid cpu scheduling technique. It works on the assumption that doing nothing (sleeping is the term there) is much more energy efficient than doing anything even if slowly, so much so that you make up the energy spent to boost to top speed.

And you can strongman this by first using the string 23456789 at the start. It does contain all base 10 digits but not 22.

That's mathematics. It do be like that sometimes. Counterexamples can be stupid but still valid.

It's on you to prove your claims.

See my other comment

Let me give another counterexample. Let x be the binary expansion of pi i.e. the infinite string representing pi in base 2.

Now you will not find 2 in this sequence by definition but it's still a non-repeating number.

Now one can validly say that we restricted our alphabet and we should look only for finite strings with digits that actually occure in the number. The answer is the string "23456789" concatenated with x.

No this does not work. Counter example can be found in the comments here of a non-repeating number that definitely does not contain all finite strings.

Edit: I think the confusion is about the word non-repeating. Non repeating does not mean a subsequence cannot repeat but that you cannot write the number as a rational or with a finite decimal representation. I.e. it's not 3.ba repeating. Where a is a finite sequence that repeats infinitely and b is a finite sequence.

Edit edit: another assumption you make is that pi does not go into a loop of some kind. You would need to prove that.

The thing is modern CPUs boost behavior is the intended, design for thing. We as humans should have a working regulator when top performance is acceptable even if damaging if sustained. A cpu also has that. That is a thermal/current/voltage limiter.

At least my takeaway from the post is that you one can't sustain a level of power/performance that is achievable in moderation / bursts.

But that's literally what the post is about. You cannot perform in burst mode sustainably. If you could that wouldn't be the top/burst speed anymore.

They really lost me there. Everybody knows everything evolved into crabs /s

A cpu will not do boost speeds sustainably. That is what its best performance is though. If I remove the thermal limiter my cpu will happily cook itself even though it is rated for 5GHz top frequency.

Edit: Saying there are no thermal constraints is like saying it will not break. You presume the conclusion there.

If there are no emotional constraints I will also function a lot better sustainably.

There is a lot of equipment that is rated for short bursts of power that would be destructive when sustained.

Military aircraft for example can often reach high speeds for a short duration. This is not improvised but designed and rated for.

Most modern CPUs have non sustainable boost speeds that they can reach but not sustain due to thermal limits.

Electric turbochargers often can only operate in short bursts.

There are countless more examples.

Can you prove this? Or link a proof?

They do this because it works on many people.

It's also about the social conflict between Vietnam and Korea veterans. Something largely forgotten today.

Now I want to know how hot Rudolph's nose would need to be such that its radiation could be picked up by these satellites.

I am sure it would still be very hot but I wouldn't be surprised if it was colder than one thinks.
