Comment Bayesian Mail Filter (Score 1) 190

I've used bmf via procmail on my ISP shell account for years, and it was extremely reliable and accurate. As an added bonus, it automatically forwarded spam to uce@ftc.gov.

When my ISP discontinued the use of procmail filters, I moved it to my home computer and configured two filters in Evolution: the first one to auto-remove mail marked by my ISP as suspected spam, and the next to pipe the mail through bmf and remove it if it tested positive for spam. When I say "auto-remove", I mean it's moved to a spam folder where I can double-check it in case false positives get through.

Comment Re:Tape drives not on list? (Score 1) 212

Hardly. I started using LTO tapes just a few years ago, taking my cue from our backup systems at the office. I have 12TB of media that I rotate between home and an off-site storage facility. A lot of my data is irreplaceable. Plus I'm a data pack rat. ;-)

Comment I'm not bothered by break-in attempts (Score 1) 241

I watch my daily security logs from time to time, but the only remote login attempts I see are my own. I can attribute this to several layers of security:

  • I'm using a dynamic IP address.
  • Access to my home network is gated through my router. Any incoming SSH connection is directed to a specific IP address on the inside, which is only configured when my computer happens to be running Linux.
  • ACL's on the router prohibit SSH connections from everywhere except specific source subnet's I've opened up, and some of those (like work) are only open at certain times during the day.
  • I'm subscribed to my Linux distributor's security updates, and apply them on a regular basis.

I won't claim that it's perfect protection, but one of the best things you can do to secure a system is to shut out all access by default and then only open tiny pinholes for the specific connections you need.

Comment This means very little to me (Score 3) 121

I've seldom trusted consumer reviews, not because they might be fake, but because "consumers" often lack enough experience with large enough numbers of competing products for their opinions to hold any weight. When I'm looking for reviews of a product, I want professional reviews from journalists who are dedicated to researching the genre.

Comment Easily worked around (Score 1) 126

The problem with claiming "innovation" in the pharmaceutical industry is that they can easily bypass existing patents simply by tweaking the processes or non-essential ingredients in creating a drug to make it just different enough to claim it as a different product. That doesn't really help society at all. The rate of discoveries of "high social value" has not risen significantly in the presence of patents. See Boldrin & Levine: "Against Intellectual Monopoly", Chapter 9.

Comment RAID + bacula (Score 2) 304

I have been using RAID for many years — RAID-1 at work as I only have two drives and don't need much storage space, and RAID-5 at home. A couple of years ago when I upgraded my computer at work, I downloaded at least three different backup systems to try out. The goals were simplicity of use, keeping historical versions of files, and relatively low storage space.

After setting up bacula, I never bothered with the other backup applications.

I found bacula to be highly flexible, adapted very well to the set of many virtual machines I use, and is the easiest to maintain. I just set it up once (or after any major re-partitioning) with a specific list of files and directories to back up or exclude, then practically forget about it. It's saved my files a number of times already from accidental deletion or overwriting, and I used it once for a full restore at home after upgrading my computer including a new RAID array.

At work my excess hard drive space is enough to store all my full and incremental backups locally, but I also have it back up critical files to a corporate NFS server. At home I use LTO-4 tapes, which provide plenty of backup storage for over 2 terabytes of data; and whenever it runs a full backup I take the used tapes off-site for extra security.

Comment Re:Patents should promote innovation (Score 2) 249

I've read evidence that industrial patents do not promote innovation, but hinder it instead. The most effective tools for profiting from either a product or a process are secrecy, complementary manufacturing, and market lead time. (Boldrin & Levine, [2008], "Against Intellectual Monopoly")

Comment Can't trust closed source apps (Score 1) 179

This is part of the reason I don't trust close-source applications that require Internet access. At least with open source I can take a look at the code and see, "hey — this program is running a key logger!" I can then modify the code and permissions and run the application without the offending network activity.

(I actually did that with one program, found on code.google.com no less. It was written with a key logger that uses a closed-source library called FlurryAgent.)

How To Stop the Next WikiLeaks 191

Hugh Pickens writes "Eli Lake reports that the U.S.'s 16 intelligence agencies are using a program called SureView that makes it easier to spy on the spies and catch whistleblowers early in the act. SureView is a type of auditing software that specializes in 'behavior-based internal monitoring' that monitors the intelligence officer's computer activity. If the officer acts like a potential leaker, sending an encrypted email or using an unregistered thumb drive, the analyst might push a button and watch a screen video of the officer's last hour of work. Once a case is made that a leak might be imminent, it is checkmate: the agent is thwarted. 'Had SureView been on Bradley Manning's machine, no one would know who Bradley Manning is today,' says Ryan Szedelo, manager for Raytheon's SureView software. The intelligence community has had auditing software for years. SureView came on the market in 2002. But the programs were buggy and often prone to false positives, alerting a network administrator too often to routine behavior. 'The technology has gotten substantially better in the last year,' says Jeffrey Harris, a former head of the National Reconnaissance Office. 'The problem with audit files was it took an army of people to understand them. Now we have rule-driven systems and expert systems that help us reason through the data.'"
