Flowgram really sucks. During my visit, whenever I clicked the forward button, it either redirected me to a page extraneous to the advertised presentation, or just didn't do anything at all.

Granted, this is my first experience with Flowgram.

The "extraneous" pages were actual slides.

I'm with you on the bad first impression of FlowGram, though.

I agree, but you have to support your statement a little more.

After staring for 10 seconds at "Loading" thingie I gave up and hit "Back". I live in 2008 with dual core machine equipped with 3GB of RAM and hooked to the Internet via 8MBit fiber connection. I don't need to wait even a second for anything, let alone 10.

i watched this all the way through (interesting stuff around slide 15) and the one question i have is how do they control sequential writing to a singular 'haystack' file that is being (artificially) capped at 10GB.

they are using offsets to seek in this large file to limit their exposure to unnecessary file metadata.
