EXT4 is a next generation file system replacement for the EXT2/EXT3 family of Linux file systems. It was accepted as "stable" in the Linux 2.6.28 kernel in October 2008[1]. As of this writing, it's starting to appear as the default file system in newer versions of several Linux distros. While the developers did try to maintain some degree of backwards compatibility with EXT2/EXT3, there is quite a bit that's new and different with EXT4. Popular forensic tools like the Sleuthkit are not fully compatible with these changes in EXT4, although some of their functionality does still work.

I finished some major updates to the site last night, including upgrading to a newer, faster core database.  I also updated our DCCTV Player Library to include new features, better performance, and better layouts.  In doing the latter I was reminded of Joe Fragomeni's significant contributions to our DCCTV Player Library, and his continued contributions here and elsewhere to the entire multimedia evidence community.

It's been a very interesting and exciting year for Magnet Forensics.  New products, new acquisitions, new training opportunities, more awards & industry recognition, and still so many exciting things to come!  Don't miss the Magnet User Summit 2024, being held in Nashville, TN April 15th through 17th, 2024.  Be sure to also check out the pre-conference training opportunities.

For the last few weeks, I have been absolutely inundated and just haven't been able to spend as much time as I'd like to further developing Media-Geek.com features and services.  The great thing about this community concept, however, is that its success does not rely on any one individual...and many others have stepped up to the plate.  At some point today I suspect we will exceed 200 active professional forensic media related members!

Recently one of our members pointed out that the Member Forum RSS Feed wasn't working, so just in case you experienced this issue I wanted to let you know it was resolved moments ago.  RSS aggregators provide a great way to stay abreast of our site content, with seperate feeds available for various content areas throughout the site. 

Thanks everybody for keeping things moving forward lately, and don't forget to tell your peers and colleagues to Sign-up, Sign-in, and Contribute!

If someone uses the phrase "DVD Quality Video" in their marketing literature it usually means one of three things; (1) their product is crap, (2) they haven't the slightest clue about DVD-Video standards, or (3) they do understand the standards and are simply trying to mislead you...and their product is crap.

Now maybe I'm being a bit harsh here, but I take offense when companies attempt to mislead the "typical" consumer by using generalizations. The fact of the matter is that there are several standards for DVD-Video, along with other variables that can impact DVD-Video picture quality.

There ARE Non-square samples, and their shape IS NOT dependent on the # of scanning lines. There are also Non-Square picture elements in CCD and CMOS image sensors, but their electrical charge is never converted to digital in an analog CCTV camera.

Back in the day there actually were Non-Square pixel-based displays, but they were only used for special applications and are not found in the wild today.

If you are aware of a standard that defines the shape of 480i (NTSC) or 576i (PAL) non-square samples differently than through the use of the luminance sampling frequencies, please bring that to my attention. Thank you.
