comment Is there a distro of Linux without GUI? What do hosting companies install?
ok - but the point stands - you can't just switch to runlevel 2 and disable the gui.

comment Why is Internet access and Wi-Fi always so terrible at large tech conferences?
Sorry - but the point is though that doing this properly is b****y expensive in kit and links as well as people. As Joel described when he was talking about how to run a $99 conference when the vendor charges you $1000 for coffee there isn't much spare money. Since the hotels don't seem to be making much money I assume they couldn't absorb the cost of your setup without noticing. The real problem of course is that you can't know in advance how good/bad the setup is and so you wouldn't be willing to pay more for a good venue's promises.

On the other hand he talks about installing a private 45Mpbs upstream link and $20,000 of custom AP for 235 users. Are you willing to pay another few $100/person for good wifi?

Typical market information problem - if one place had stellar coverage but charged more to cover it, how many customers would understand that in advance over the other cheaper place who advertise "#1 A double plus good" coverage?

BYO isn't an option when a trade show is charging you $1000 for network access to your booth.

comment backing up large database with large amount of data in a small time limit then restoring it within a small time of limit?
But you have to be sure that the state of the database is valid to be copied while the DB is running.

comment Copying a large directory tree locally? cp or rsync?
The cpu overhead of the checksum is small compared to the disk/network i/o. Unless the disk are on the same system and the OS can do some clever drive-drive copy in the bus controller.

comment Any benefit or detriment from removing a pagefile on an 8GB RAM machine?
On Solaris it was/is even more involved. The swap file is mirroed in a ram disk like tmpfs so the memory is always almost full - but it is apparently provable that this is the optimal strategy.
