Re: 1638: "Backslashes"

And as usual for the internetz, there's a cat involved in this comic (not to mention the quite serious UNIXy discussion here) :lol:

Re: 1103: "Nine"

My microwave uses an "analog" pot to set time, but to compensate, I never set up my morning alarm to an "exact" hour. I'd never dial in 9:00, it would be 8:57 or 9:09, or anything in the vicinity. I thought I was the only one doing this, but it turns out it is quite a common patt...

Re: 1039: "RuBisCO"

This comic made me recall Eurotrip, the Amsterdam scene. Was very surprised that this hasn't been mentioned in the thread yet.

Re: "Ahead Stop" discussion (#781)

Second driving/highway related comic in a row... I would guess that Randall has wasted a lot of time in driving recently. :)

Re: "Dependencies" discussion(#754)

In addition to the things mentioned by smartboyathome: also, *ANY* self-respecting programming language has a reference compiler written in the same language. You need C to compile GCC, a C compiler, and you need Free Pascal to compile Free Pascal. Same goes for Haskell, Lisp, Python, etc. . People ...

Re: "Semicontrolled Demolition" Discussion

One half of the Chernobyl reactor #4 exploded due to an operator error. The other half was just badly designed.

Re: What would you do with an infinitely fast computer?

I strictly disagree with you. There's a fallacy in your logic, which I think comes from that you implicitly assume you can run an infinite algorithm on the infinite computer. Let's propose the following simplified framework: each instruction on the infinite computer takes some time k, which is incr...

Re: What would you do with an infinitely fast computer?

I think Yakk is assuming that the infinite computer can run a countably infinite number of steps in finite wall time (which seems reasonable for any definition of 'infinitely fast computer') and has unbounded memory (for reasons discussed). Since the set of programs which halt is countable, and eac...

Re: What would you do with an infinitely fast computer?

Huh? You'll finish running that in at most Graham's number cubed iterations of my triangle algorithm, roughly (O(max( algorithm number, halting steps )^3 ) to be formal). I don't need to change what I described one iota. ... Supposing the algorithm that takes graham's number steps to halt is earlie...

Re: What would you do with an infinitely fast computer?

I don't see a problem. I thought you'd fall in this trap. As you correctly stated, the situation with finite memory is not interesting at all. You'd enumerate and correctly execute all halting programs that fit in memory. But you wouldn't execute an infinite number of programs that don't fit, so yo...

Re: What would you do with an infinitely fast computer?

Do a triangle walk. Enumerate programs 1 through infinity. Run program 1 for 1 step. Run programs 1 through 2 for 2 steps. Run programs 1 through 3 for 3 steps. ... Notice that this runs every program for an arbitrary number of steps. Nah, this logic doesn't work because of two things: 1) More gene...

Re: What would you do with an infinitely fast computer?

I would make a program that generates every possible program and runs it. After 0 seconds I would have already done everything that is in this thread and everything that isn't. I win. You don't win, because you cannot do that. Just that the computer is infinitely fast doesn't mean you can execute a...

Re: What would you do with an infinitely fast computer?

Argh! I was just about to create a thread like this one :mrgreen: Anyway, here's the list of things I'd do: 1) Calculate the next 10 Mersenne primes. Then I'd contact GIMPS to request a few small private exponent subranges to test myself, chosen in a way that they contain the primes and launch the s...

Re: "Estimation" Discussion

Today I was clearing off a hard drive for an old Win98 computer to dual-boot a lightweight linux, and the time remaining number kept climbing up higher and higher. I got a cell phone picture (horrible quality) at 2.5 million MINUTES . It peaked around 5 million minutes, then instantly dropped back ...

Keyboard shortcuts for the comic

Hi, I've been reading the comic (and comment threads occasionally) for some years now and I thought it would be cool if there were some keyboard shortcuts to do "< Prev", "Random" and "Next >" on the comic page. I regularly watch a series of comics to kill a few minutes...
