Homebrew CPU
Magic-1 is a homebuilt minicomputer. It doesn't use an off-the-shelf microprocessor, but rather has a custom CPU made out of 74 Series TTL chips. Altogether there are more than 200 chips in Magic-1 connected together with thousands of individually wrapped wires. And, it works. Not only the hardware, but there's also a full ANSI C compiler for Magic-1 (retargeted LCC), and a rudimentary homebrew operating system. You can even telnet into Magic-1 and play Original Adventure.

[SecurityFocus] Oracle taken to task for time to fix vulnerabilities. Després d'esperar 650 dies a que Oracle publiqués l'actualització per eliminar sis vulnerabilitats crítiques, es publiquen els detalls de les mateixes.
The public release of the advisories--along with instructions outlining techniques to exploit all but one of the flaws--marks the latest incident between independent security researchers and software companies, two groups frequently at odds over when, or even if, to disclose vulnerabilities.
(...)
Red Database Security told Oracle of the flaws between July and September of 2003, according to the security firm's advisories. The company communicated with Oracle about the issues and, three months ago, gave the database maker until the July quarterly patch to fix the issues.
(...)
decided to publish these vulnerabilities because it is possible to mitigate the risk of these vulnerabilities by using the workarounds provided in the advisories," Red Database's Kornbrust said in the explanation introducing each flaw report. The reports were posted to the company's Web site, to the Full-Disclosure mailing list, and to the BugTraq mailing list, which is operated by SecurityFocus.
The high-severity flaws occur in the Oracle Forms and Oracle Reports components included in various versions of Oracle's Application Server and could allow an attacker to execute program code. Another flaw, also in Oracle Reports, could allow an attacker to overwrite files on the targeted server. The three remaining flaws are of lesser severity, according to Red Database.
