R.I.P. Floppy Disk

Sony has announced that it is ending production of the venerable 3.5” floppy disk. Additional coverage at Ars Technica.

Things like this cause me to wax nostalgic (a sure sign of advancing age, at least in Internet terms,) but I’ll simply recall that my first OS (MS-DOS) came on something like 3-4 floppies. We also thought the boot-sector viruses that often rode around on floppies were a terrible scourge. If only we’d known what was to come.

Will Accept Smart Grid In Lieu Of Jetpack

So, it’s almost 2010 and there’s no sign of my jetpack. That’s fine, it probably wasn’t such a great idea anyway (it would suck to commute in the rain). What I am excited about is smart power grids.

I love finding out the origins of terms that we all take for granted and about which we don’t usually think in depth. Thanks, Ed.

Welcome to the Future

Where’s my jetpack?

Happy 2008. We’re a little behind, you know. We’re supposed to be going to Jupiter by 2010. As it stands, we might make it to Mars in my lifetime. Apparently we’re too busy with all the other pressing matters before us.
