Submission + - Ask Slashdot: What's a good tool to detect corrupted files?

Volanin writes: Currently I use a triple boot system in my Macbook containing MacOS Lion, Windows 7 and finally Ubuntu Precise, on which I spend the great majority of my time. To share files between these systems, I have created a huge HFS+ home partition (MacOS native format which can also be read in Linux, and in Windows with Paragon HFS). But last week, while working on Ubuntu, my battery ran out and the computer suddenly powered off. When I powered it on again, the filesystem integrity was ok (after a scandisk by MacOS), but a lot of my files contents were silently corrupted (and my last backup was from August...). Mostly, these files are JPG pictures, MP3 musics and MPG/MOV videos with a few PDFs scattered around. I want to get rid of the corrupted files, since they waste space uselessly, but the only way I have to check for corruption is opening one by one. Is there a good set of tools to verify the integrity by filetype, so I can detect (and delete) my bad files?

Submission + - When Was Slashdot's Heyday? 5

An anonymous reader writes: In the past few years, Slashdot editors have introduced a multitude of changes to our site that have been met with mostly negative comments. Yesterday, SlashdotBI was introduced. A few weeks ago, Slashdot editors announced plans for their SlashdotTV. Slashdot's last overhaul occurred on January 25th 2011, which revamped the existing HTML and CSS code. In all of these announcements and many more, a multitude of Slashdot users have expressed concern that the site simply is not good enough as it was in the past. This concern goes back all the way to a 2000 Geeks in Space episode, where Rob "CmdrTaco" Malda asked the GIS panel: "When did Slashdot start sucking?" A lot of people reminisce about "the good old days" and how things were inherently "better" back then. My question to Slashdot users everywhere is: Is Slashdot's best years gone? When was Slashdot's heyday in terms of popularity, enjoyment, information, and intelligent discussions? How can Slashdot return back to what many users regard as their former glory?

Submission + - Email Systems 5

OneC0de writes: I have been the IT admin for a small/medium business for the last 3+ years. Currently our email system is a IMAP/POP/SMTP setup hosted through another company across the country. We've continually had email problems ranging from dropped connections, and missed messages, to our host forcing our users to a 500MB inbox which we regularly have to flush. We have Small Business Server 2008 in-house running our active directory/group policy. I have normally setup Exchange on SBS for most of my clients but this business in particular is pretty against Exchange (being a Windows product). The owners are ready to upgrade their email system, but are not sold on going to Exchange. Many users at this company are on Thunderbird and don't want to make the switch to Outlook. The owners have asked me to find other email server solutions. One thing their "Linux friend" suggested was iRedMail. They definitely want to host it in-house to save on cost and increase connectivity while at the main office where most emails are done. Many users in the office have 2GB — 10GB of emails stored from the last 7+ years, just on their local machines (not being backed up regularly). Right now there is no shared calendars, or global contact list but they don't see that as a much needed feature anyways. We also use SquirrelMail 1.49 for web access, but it seems old and outdated.

So I guess my question is, are there open-source, or cheap mail servers you would recommend? Is there a good argument for Exchange other than (it's free and sitting in your server room right now, just need to "turn it on")? Would you recommend Exchange or go against it? One of the things the owners would like is anti-spam, anti-virus, and maybe some kind of archiving capabilities. Many users in the office also have mobile phones and would like access to the emails while on the go. Suggestions, comments, complaints, free beer?
