• [Old] US NIST ☛ Digital Forensics Using Perl to Harvest Hash Sets [PDF]

  For many reasons, the NSRL project is migrating to an open source environment, specifically using Linux, Apache, MySQL and Perl (LAMP) for the core technologies. To this end, our goal is to develop Perl code that can be used by computing nodes, running various operating systems (e.g. Windows, Linux, Mac OS), using common modules available from the Comprehensive Perl Archive Network (CPAN www.cpan.org). We have accomplished this for the actual calculation of the hash values; Digest::SHA version 4.3.1, Digest::MD5 version 2.33, Digest::MD4 version 1.3 and String::CRC32 version 1.2 have proven that they provide the expected results

  However, the computing nodes must both hash every file encountered and hash the contents of any "archive" type of file (e.g. zip file, tar file, cab file, uuencoded file). The diversity of the operating systems and possible archive file formats means that we need to provide an interface to allow third party applications to process the archive files unless and until Perl modules exist to handle these formats and can be tested.

• Anne Sturdivant ☛ What are Tiny Pages?

  A large refactor of weblog's base (and component) styles should include this new base, and use many of the new modern CSS tools we have now to work with, including CSS cascade layers. In order to get up-to-speed on many of the new tools, some which I've only read about, others I've used but not done a deep dive, I want to create individual case studies for each tool or set of tools. These will be done on tiny pages themselves but work to create a Tiny Pages base, so-called because I am aiming for a small footprint.

• Tony Finch ☛ sudon't – Tony Finch

  3. For auditing.

  I doubt I have ever seen or heard of sudo’s logs being used effectively.

  But (assuming there is in fact some practical use to it) sudo was better at logging who did what than other privilege escalation tools, such as login or su. In particular, sshd was for a long time unable to log which public key was used to authenticate, which is a sad omission especially for shared privileged accounts such as root.

• University of Toronto ☛ UEFI, BIOS, and other confusing x86 PC (firmware) terms

  IBM compatible x86 PCs have come with firmware since their first days. This firmware was called (the) BIOS, and so over time 'BIOS' became the generic term for 'IBM compatible x86 PC firmware' (which could come from various companies who carefully reimplemented it from scratch in ways that didn't violate IBM's copyrights). Over time, PC firmware ('BIOS') got more complex and acquired more (boot time) user interface features, like all sorts of splash screens, tuning options, semi-graphical interfaces, and so on. However, the actual BIOS API, primarily used at boot time, stayed more or less unchanged and as a result PCs kept booting in a simple and limited way, (mostly) using the Master Boot Record (MBR).
