MACLISP manual (The Pitmanual)

Από το maclisp.info:

“MACLISP is a dialect of the LISP Programming Language that ran on DEC PDP10 and Honeywell Multics in the 1970’s and early 1980’s. […] The long-awaited, comprehensive summary of MACLISP, a webbed version of Kent Pitman’s The Revised Maclisp Manual, is finally available.”

5 Rules of Data Normalization poster

Χρειάζεστε ένα γρήγορο ξεσκόνισμα στις κανονικές μορφές; Αυτό το poster από το 1989 είναι αρκετά βολικό. Και μια και το έφερε η κουβέντα, εάν σας περισσεύουν $10, ορίστε τι έχει να πει ο C.J. Date για την πρώτη κανονική μορφή (1NF): What First Normal Form Really Means.

HostDB: The Best Damn host2DNS/DHCP Script Ever Written

Το είδα σήμερα στο Everything Sysadmin. Θα ήθελα να γράψω περισσότερα για το εργαλείο, αφού το δοκίμαζα πρώτα, αλλά “There’s only 20 people on the mailing list“. Οπότε γράφω το post για να μάθει περισσότερος κόσμος για το εργαλείο. Άλλωστε ο Tom Limoncelli δε γράφει μπούρδες.

2007 ACM Turing Award

O Ιωσήφ Σηφάκης, αν δε κάνω λάθος, είναι ο πρώτος Έλληνας στον οποίο απονέμεται βραβείο Turing (θα μπορούσαμε να πούμε το αντίστοιχο του Nobel Prize για τους Πληροφορικούς). Από την ανακοίνωση της ACM:

“ACM, the Association for Computing Machinery, has named Edmund M. Clarke, E. Allen Emerson, and Joseph Sifakis the winners of the 2007 A.M. Turing Award, widely considered the most prestigious award in computing, for their original and continuing research in a quality assurance process known as Model Checking. Their innovations transformed this approach from a theoretical technique to a highly effective verification technology that enables computer hardware and software engineers to find errors efficiently in complex system designs. This transformation has resulted in increased assurance that the systems perform as intended by the designers.”

Ένα πρόσφατο και εξαιρετικό άρθρο του κ. Σηφάκη μπορεί να βρει κανείς στο IEEE/Computer: The Discipline of Embedded Systems Design (mirror εδώ).

HOWTO: Resetting a Communicator 9500 to factory defaults

(This is the result of googling arround for sometime)

If you happen to have a Nokia Communicator 9500, you might want to reset it to factory defaults. You have two options to accomplish that and here is how:

* Remove the battery.
* Place it back.
* For as long as the Nokia handshake is visible on the PDA screen, keep CTRL-SHIFT-F pressed. After a while a menu is displayed asking whether you want to reset to factory defaults or not.
Use Rebooter, the excellent freeware utility of Roman Keller; available for download from SymbianGear.com.

Microsoft offers to buy Yahoo for $44.6 billion

Η είδηση “γεμίζει” το Hacker News: Η Microsoft θέλει να αγοράσει το Yahoo!

Είναι ώρα να κάνω επανάλληψη στο “The Nature of the Firm“:

“[…] why, if by organizing one can eliminate certain costs and in fact reduce the cost of production, are there any market transactions at all? Why is not ah all production carried on by one big firm? “

Υ.Γ. Μη ξεχνάμε, billion = 10⁹ και όχι 10¹²

Update (2008/05/04): Microsoft withdraws its proposal.

IT audit forum

Steve Shofner wrote to cisaca-l:

I was recently looking for other good sources of information regarding
IT Audit on the web, discussion groups in particular. There aren’t too
many. So, I’ve started one in Google Groups. It is a place for IT
Auditors to ask questions, get answers, and collaborate on IT Audit
matters.

This Purdue group is a great resource. However, if you, like me, are
also interested in other points of view as well, please check out the
following link: http://groups.google.com/group/it-audit-forum

I’ll be leaving some invitations with other groups as well. So,
hopefully, it will blossom into another diverse resource for
information.

Please spread the word….

Spreading the word then.
