Re: Logical equivalence

This is an example of converse vs contrapositive. The contrapositive of a proposition is always true if the proposition is true, while the converse is not necessarily true. No it isn't. For an implication p -> q: its contrapositive is ~q -> ~p and its converse is q -> p. No implication is present i...

Re: Why can't we talk to our computers yet?

In order to talk to your computer, you'd have to use some sort of standard language. I mean, it's theoretically possible to emulate the language processing of a brain; but that's insanely complicated and still not perfect or cleanly converted machine instructions. Speech to text of say, bash script,...

Re: Office

I don't really bother with Office that much. It's definitely not worth spending money on; it's not even worth pirating as far as I'm concerned. Honestly if I need a quick word processor I just use Google Docs, and I have OpenOffice installed on my computers so I can easily read any M$ docs I come ac...

Re: Is Java is a bad language for beginners?

TBH, OOP still feels like a dumb abstraction to me. It's not how code actually runs. If you write in C, getting your hands dirty with pointers and dynamic memory, you get a lot closer to the The Real Thing, and it makes actually understanding CPU & memory architecture a lot easier. Though I have...

Re: Debian vs Ubuntu

Ubuntu was my first serious experience with Linux. But this time around I've decided to stick with Debian and I'm liking it. It has GNOME and the repositories, so I don't feel like I'm missing anything. Plus, any functional OS+GUI that will run smoothly on a P3 with 256MB of RAM gets a thumbs up IMO...

I was under the impression that most lead-acid UPSs use shallow-cell batteries, especially in that price range. A few deep discharges and that thing will likely be toast.

Re: do errors 'hurt' my PC?

First off all, an "error" in compiling means the compilation didn't work. The machine code either wasn't generated or was immediately discarded. So no damage there. Depending on your BIOS it is possible, I think, to change clock speed multipliers or force off fans. It is extraordinary unli...

Re: Python List Comprehension for Prime Numbers

Cool. Now I have it working in one line: print [x for x in range(2,1000) if not [y for y in range(2, int(x**0.5)+1) if x%y ==0]] I guess adding 1 to the square root of your factor range is important. Here's a better way. Yikes. What do these lines do? s = [False]*2 + [True]*(n-2) and s[i*i : n : i] ...

Re: Why did you switch to Java?

I learned with C/C++, but I started using Java because it's incredibly easy to make powerful programs that do everything C/C++ can do, except instead of dealing with terrible conventions or weird syntax (seriously, do we need to differentiate between a pointer and direct reference in this day and a...

Re: Python List Comprehension for Prime Numbers

Yes, thanks, that's the comp. I'm looking for. But, for some reason, if I change the comp. to only check the factors through num**0.5, it ends up not working right and gives several composite numbers. Also for some reason my createprimelist is giving me some weird syntax error. def isprime(num): ret...

Re: Should I pay for Yahoo Mail Plus?

But I'm thinking of ponying up the $20 for POP3 access, for two reasons.

GMail offers that, and so much more, for free. Plus even with the free version you only have a few, unobtrusive text-based ads.

Re: Python List Comprehension for Pime Numbers

That recursively defined (?) list comp. is pretty cool. I'll have to look over it. I've seen that technique, or something similar, used before, but I specifically didn't want to do something like that (i.e. creating a list of composite numbers). I wanted to do something like: for num in range(blah) ...

Python List Comprehension for Prime Numbers

In an attempt to wrap my head around Python's list comprehension, I wrote a program that uses list comprehension to assemble a list of prime numbers. Here's what I have so far, though it's not as concise as I want it to be: list = [] for i in range(2,1000): primeflag=True for num in list: if(i%num==...
