25 years ago, around this period, the InterBase 6 / Firebird 1 prerelease gaping security hole was detected: a user politically with password correct would gain database access

Posted by jpluimers on 2025/12/24

Before Firebird version 1.0 got released, a gaping security hole that InterBase introduced in 1994 before InterBase 6.0 (mostly written in C) got open sourced in 2000 was detected by the team that frantically tried the Firebird fork to first get building on various platforms, then released.

It had a maximum CVSS score of 10.0 because it could access the security database in read/write mode, thereby allowing adding users with SYSDBA privileges.

The detection is now about 25 years ago; on 20260109 the publication (by IBPhoenix) of the bug will be 25 years ago too.

So below are some links, including the original InterBase 6 source which was hard to find as the attachments of the original release links had not been archived in the Wayback Machine.

But first some of the code parts, which also shows the source file I did find back:

defaults read /Library/Preferences/SystemConfiguration/com.apple.airport.preferences |grep SSIDString
In prior versions of Mac OS X, you can opt for the same as the above command, or use the lengthier string below with heavy regex:

Chrome/chromium gripe: cumbersome screenshots; Firefox much better (but management hates employees having cancer)

Posted by jpluimers on 2025/12/22

  • Ctrl + Shift + S on Windows/Linux/Chrome OS
  • Command + Shift + S on MacOS

Too bad Mozilla also appears to be amongst the bad guys in firing an employee having cancer ¹.

On Chrome not so much and require opening the Chrome Developer Tools which take up precious screen estate, and saves the screenshot in the downloads folder instead of the clipboard. Many guides exist, for instance:

Adobe Photoshop Source Code – CHM

Posted by jpluimers on 2025/12/19

With the permission of Adobe Systems Inc., the Computer History Museum is pleased to make available, for non-commercial use, the source code to the 1990 version 1.0.1 of Photoshop. All the code is here with the exception of the MacApp applications library that was licensed from Apple. There are 179 files in the zipped folder, comprising about 128,000 lines of mostly uncommented but well-structured code. By line count, about 75% of the code is in Pascal, about 15% is in 68000 assembler language, and the rest is data of various sorts.
