Re: Accessing Linux Applications From Within MS Windows

Just my $0.02, but I far prefer VNC to X tunneling. X tunnels always feel a bit laggy to me.

... and X-tunnelled emacs looks crappy on my work machine, but that's probably not universal :).

Re: Google Interview Question: A fully Multithreaded Approa

Really interesting. I'm not sure I get the math - how does one arrive at the 10^(2.44*10^6) value? multichoose is a derivative of choose from probability.

Re: Google Interview Question: A fully Multithreaded Approa

Your differential encoding scheme is clever, but I think it fails if given adversarial input. For example, what if the given numbers are "1, 99999999, 1, 99999999, ...."? Since you'll need 4 bytes to encode each difference, the encoded set won't fit in 1 MB. In my implementation I sort th...

Re: Google Interview Question: A fully Multithreaded Approa

Yeah, ok, epic fail on my part. Sort and store is the question, I should've focused on answering that. Differential encoding + insertion sort (as other, smarter posters have said) is the way to go :).

Re: Google Interview Question: A fully Multithreaded Approa

OK, so I guess the storing is actually interesting after all, based on my edit above. The encoding I would use is a variable length integer, encoded as a series of bytes where the topmost bit indicates a stop bit. I think that should allow you to encode each offset using an average of 8 bits per off...

Re: Google Interview Question: A fully Multithreaded Approa

The point of this question is the sort, not the store. The answer to the storage part is "using disk". (Storing 1M 4-byte integers in 1MB is just not possible, in general. There's more entropy than bits to encode it.) Sorry, I realized that's only true if the array is unordered...

Re: How does Xeon E 5645 2.4 GHz compare to i-7 2600K 3.4 GH

The E5645 is capable of dual-socket operation, so if you're using a single socket system and running lightly threaded applications to boot, then you're paying a premium for the wrong chip! If you look at the uni-socket Sandy Bridge Xeons, the prices are pretty comparable to the consumer gear.

I'd say three 1333MHz DDR channels per socket is not a bad attempt for memory bandwidth.
