Submission + - Forensics Expert says Al-Qaeda Images Altered

WerewolfOfVulcan writes: Wired reports that researcher Neal Krawetz revealed some veeeeeery interesting things about the Al-Qaeda images that our government loves to show off.

From the article: "Krawetz was also able to determine that the writing on the banner behind al-Zawahiri's head was added to the image afterward. In the second picture above showing the results of the error level analysis, the light clusters on the image indicate areas of the image that were added or changed. The subtitles and logos in the upper right and lower left corners (IntelCenter is an organization that monitors terrorist activity and As-Sahab is the video production branch of al Qaeda) were all added at the same time, while the banner writing was added at a different time, likely around the same time that al-Zawahiri was added, Krawetz says." Why would Al-Qaeda add an IntelCenter logo to their video? Why would IntelCenter add an Al-Qaeda logo? Methinks we have bigger fish to fry than Gonzo and his fired attorneys... }:-) The article contains links to Krawetz's presentation and the source code he used to analyze the photos.

Chances are you're just a rabid anti-Notes troll, but I'll bite anyway.

Lotus Domino and Microsoft Exchange are different products: the first is a "groupware" platform that happens to do mail, the other is a mail server that might be linked to some other Microsoft platforms (notably: sharepoint). The Notes client can be used for accessing "databases" (which are actually a container with semi-structured data and application logic in one), for which IBM provides a "mail database" that is kinda capable of handling mail. Outlook is a superb mail client that does nothing else unless you've got someone willing to create "outlook foms" that link to other MS technologies.

The good about Domino/Notes:

  • Domino is multiplatform, Notes kinda (current Linux client is barely usable)
  • Security is a design fundamental in Notes/Domino. Notes has been doing private key crypto and signed code before Exchange was even conceived.
  • Domino/Notes is way better when integration company processes/workflows in your mail environment.
  • Restoring backed up mails/documents/databases can be done relatively easy, and has been like that for at least 12 years.
The bad:
  • The Notes UI is infamous because it is so different from Windows and counter-intuitive to some people. This is for the major part historical (i.e.: Notes has been developed as a multiplatform client, and it includes a lot of legacy). If you want you can easily update the design of your mail database and replace it with an open source one (try that with Outlook ;-) -- see for that. If you really want, you can just use outlook with Lotus Domino natively with the DAMO plugin.
  • The learning curve for Domino administration is steeper than that of MS Exchange. The impact of a good administrator versus a not-so-good one will be much more visible in a Domino environment than in an Exchange/outlook environment. Getting both to go further than a couple of machines requires good admins regardless of the technology
The actual cost per user won't differ that much between either platform, and the featureset is different. If you're a Microsoft shop and have an all-windows datacenter, SQL Server, Sharepoint portal and whatnot you'll be installing Exchange. If you're not already linked as much to Microsoft technologies chances are that Domino/Notes is a better choice. If you're sensitive regarding security (or having to abide to certain security regulations), Domino/Notes is probably your best shot (a lot of banks think so, anyway).

So, it's not a black and white issue, and there are very good reasons why Notes and Domino can be a better choice for a particular situation.

Disclaimer: I know a thing or two about IBM/Lotus technologies (and of Microsoft and Linux, so don't hold that against me ;-)
