Take what you wish, leave the rest in peace.


Look with all your eyes, look. -Jules Verne

The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. -H.P. Lovecraft

Freedom has no barcode. -J.G. Ballard

RELIGION, n. A daughter of Hope and Fear, explaining to Ignorance the nature of the Unknowable. -Ambrose Bierce

There is something to be learned from a rainstorm. When meeting with a sudden shower, you try not to get wet and run quickly along the road. But doing such things as passing under the eaves of houses, you still get wet. When you are resolved from the beginning, you will not be perplexed, though you still get the same soaking. This understanding extends to everything. -Yamamoto Tsunetomo

Who then is free? The wise man, who is lord over himself, whom neither poverty, or death, nor bonds affright, who bravely defies his passions, and scorns ambition, who in himself is whole and rounded, so that nothing outside can rest on the polished surface, and against whom Fortune in her onset is ever defeated. -Horace

Quis custodiet ipsos custodes?

Who will watch the watchers? -Juvenal

It takes a very long time to become young. -Pablo Picasso

Brother HL-2170W 23ppm Laser Printer with Wireless and Wired Network Interfaces

Posted by John on 24th August 2009

It was also time to drop the the old inkjet beast off at the component recycler; wanted to make the most of any drive over there. After considerable research I chose a good home black and white laser printer :

Brother HL-2170W 23ppm Laser Printer with Wireless and Wired Network Interfaces

Figuring conservatively (getting 80% of rated service on toner / drum, etc.) and rounding up (to more expensive) it looks to work out to about 3.1 cents per page, for the hardware side of things, over the cost-effective life of the printer before recycling it. (the drum is too expensive; at 12k sheets, it’s less expensive to recycle and start again; of course, 12k will likely never happen for me, hah).

Add paper costs (obtained locally) of another .9 cents for nice, jam-resistant in the past “internal use quality” paper, about 4 cents a page. Costs go down with “more enterprise grade” hardware, but up-front costs sure rise. I will manually duplex the tiny amount of printouts I need per month, since it’s a rare day that I actually print a page. I just got tired of inkjet “tech” drying out, and in my limited experience this isn’t a factor with lasers.

CanoScan 8800F film and negative scanner

Posted by John on 24th August 2009

Just ordered a new multi-purpose scanner, I was long overdue.


Canon CanoScan 8800F Color Film/Negative/Photo/Document Scanner

Max. Power Consumption 18W (1.5W standby) seems pretty good.

It’s Energy Star rated, etc. and it’s gotten pretty good reviews for film, negatives, and slides besides the usual scan objects.

Then you see Canon’s top non-film scanner for the home / home office market (aka me) :

Canon LiDE200 Color Image Scanner

2.5W (1.4W Standby) – USB power only, no power converter or cable needed. one wire, yup.

I know that’s geekdom, but that’s pretty cool for the scan device to be using a whopping 2.5 watts while actively scanning in documents, etc. Even though I went for the first one, and will leave it unplugged when not in use (the vast majority of the time) the efficiency of the standard one is intriguing.

How to Encrypt and Erase a Hard Drive by Digital Trends

Posted by John on 24th August 2009

Reasonable and basic intro for folks.

How to Encrypt and Erase a Hard Drive – by Digital Trends 2009 08/23

One thing many neglect : a true benefit of running your hard disks as FDE / Full Disk Encryption is that when you are done, there should be nothing to erase; the data is useless without your high-quality key.

Excerpt :


We discussed the importance of backing up the data stored on your computer’s hard drive in a previous story. But what happens if your computer is lost or stolen? Notebooks are particularly vulnerable. A thoroughly executed back-up plan will alleviate data loss, but do you want strangers perusing the highly personal information you’ve stored on that machine? We didn’t think so; that’s why we put together this guide to keeping your electronic data secure.

First, we’ll take you through the process of encrypting the data on your hard drive, so that you can use passwords to control who can see it. And since no computer lasts forever, we’ll show you how to scrub your hard drive so that no one will ever be able to retrieve anything from it when you decide it’s time to put it out to pasture.


Of course, I’ve enjoying watching many a hard drive scrub, and then sleep with the fishes. Commercial hard drive shredding is a fun day at the office ;)
