Turning off auto-email checks would probably make me a lot more productive. Juha Haataja writes:

available immediately! There is a recent report
(in PDF) about the cost of e-mail interruption: “The time it takes the
average employee to recover from an email interrupt and to return to
their work at the same work rate at which they left it, is on average
64 seconds.” Thus, if you receive 50 e-mails in a day, you might lose
almost on hour of productive time. Thus, setting in your mail program
the interval between e-mail checks to one hour is a good tactic, as is
disabling all notifications of received e-mail.

A recent /. post prod me to do some research on CD-Rs for archival purposes. It looks like the MAM-A (and MAM-E in Europe) lines of CD-Rs, with the combination of Phtalocyanine dye and superior uniformity/quality make it ideal for archiving (and it looks like there aren’t many other players in the market anymore). Their top of the line Gold/Gold (650MiB) goes for $0.94/pop in quantities of 100 ($1.48/GiB), while the Silver/Gold (700MiB) can is $0.66 in quantities of 100 ($0.97/GiB).

Of course, doing large backups makes one wonder, why not DVD-Rs? And why not? A 50/pack of MAM-A DVD-Rs is $169.99 for 50, which comes out to $3.40/disc, or $0.78/GiB.

BTW, doing searching for the cost/GiB conversions has firmly convinced me that separate binary unit notation really is needed, otherwise evil marketing causes confusion.

• DVD FAQ: DVD-R – interestingly enough, while CD-Rs are sold labeled in MiBs, DVD-Rs aren’t.
• MAM-A Technology: Technical Papers – some actually useful information here
• Mitsui Chemicals sells CD-R/DVD-R production – trivia bits; MAM stands for Mitsui Advanced Media

So, I’m not quite running around with my head cut off, but I haven’t really had a chance to post anything recently. Last week was spent trying to tie up loose ends, filling out lots of paperwork (class registration, financial crap, etc.) and this weekend was topped off by coming down with a nice little bug. My first class starts tomorrow, so we’ll see how it goes. In the meantime, I’ve realized that I’ve acquired almost 40 open browser windows (it’d be too scary to count the number of tabs).

• iSpeakIt – takes a webpage and converts it w/ Text-to-speech into sound-file — hmm, not to impugn the authors here, but selling this for $10? This is pretty trivial to do w/ standard system calls (probably can be done in Applescript even).

  My thoughts: listings are fine, but for large sites, it probably makes sense to organize by role (more specifically function) – need to come back to this later

Matt has a writeup of how the Lazyweb helped him set up VNC to get his PC and Mac to happily coexist.

Hey, notice that windowsupdate.com is now running Linux? via, Akamai, but still, a good poke in the eye regardless. As if Blaster and Sobig.F in a week weren’t enough.

I haven’t been keeping track of BlogShares much, although it looks like my site’s been doing pretty well recently. With how busy I’m going to be this fall, I’m sure to be spending more time than ever on the blog.^*

A WikiWhiteboard with SVG would be perfect for mapping out stuff. Actually, having relational diagramming primitives and multiple layers would be perfect, but beggars can’t be choosers (one step at a time). via paranoidfish

I started noticing the worm spoofs this morning around 10AM. Doing some legwork seemed to reveal it as a Sobig variant, and about a half hour later the virus definition popped up in the AV scanner. Around the net, a lot of people are clarifying that this isn’t an “email worm,” but a “Windows worm,” which in some sense is true, however, while the worm only propagates through infected W32 machines, the spoofings/spoofed bounces affect (and highlight the problems) of the entire email system, and highlight the need to some sort of authN/dsig system.

Perhaps signed headers would be a simple way of solving the problem – it’d require some extra key servers, but you could implement this on a per-server basis, or even the user level (mta level would be better, it would save bandwidth and allow realms of trust), and is completely backwards compatible…

(While perhaps resource intensive, it would certainly create a trusted path, and could be done completely voluntarily (ie, deployed when the cost of sifting/sending bad emails outweighs the cost of the decrypting the signatures of each message).

todo: look up proposals for various systems/frameworks that can verify paths, senders, recipients, but still maintain some semblance of privacy or anonymity
