Those two books looks like OReilly ones. I found one with [a similar bird sketch](http://shop.oreilly.com/product/9780596809577.do#),

It's obviously meant to be an O'Relliy SSH book, but it's not the real O'Reilly SSH cover (pictured here in the JP edition: http://www.oreilly.co.jp/books/images/picture_large4-87311-287-7.jpeg )

@channel is indeed a reference to 2channel (hint: Shift key)

@AkiTanaka depends very much on the keyboard layout.

@Worse_Username What do you mean? Are there keyboards that don't output @ when Shift+2 is pressed?

@Wally: Most European keyboards have " on Shift-2, @ is shift-' e.g. on the UK layout: https://en.wikipedia.org/wiki/QWERTY#United_Kingdom

<p>I believe the company that they were fighting against,'SERN', is an obvious reference to the company CERN. SERN is known to operate the largest particle physics laboratory in the world, the same goes for the real CERN.</p>

Just like John Titor actually *existed* (most likely as a made-up character, but still). But this isn't programming nor computer-related, and neither is SERN/CERN.

<p>For example, I noticed the SQL database is referenced.</p>

SQL is mentioned, as the question suggests. They even used company and trademarked names:

Of particular interest is the fact that Oracle, the company that owns Java, is present. It's rare to find original trademarks in anime.

A book for "Goodle Endroid", a clear reference to Google Android, can also be seen:
