Apparently... very old radar guns were calibrated with a tuning-fork by the operator before use. If the tuning-fork was damaged, abused, mishandled its frequency would change. Using it would cause the radar to be miscalibrated.
At http://fsbench.netnation.com/ you'll find a nice python tool that will run Bonnie and/or IOzone with different parameters and stick the results in a MySQL database and make nice little tables from the data.
There is also some commentary and recommendations based on their results.
One more note about the tool... it's not well documented but works well when configured... note that you need a kernel that supports the filesystems to be tested (duh!), Use python 2.2, the database schema is somewhere in the comments.
First time I had seen this technique used was in 1994 when I was working for a medium sized subcontract assembly shop in Markham, Ontario.
The SMT pick and place machine was already installed and running. The owner wanted to start up a small run of a few 10s of boards before I was able to commision the Second hand SMT reflow oven he had purchased.
I decided that I wouldn't use the toaster oven to warm up my lunch after that.
The reflow oven's control system was a PC running windows 3.1. One could play minesweeper or solitaire while waiting for the boards to come out the other end when fine tuning a profile.
I used to visit Active Surplus regularly when I was a teenage geek (80s). Now I only visit Toronto once or twice in two years so I try to make the
pilgrimage when in town at least to see what stuff is still their from the 80s, 5 years ago, and what's new and interesting.
In the early 90s an aquaintance told me that Active started out in the 70s buying old computers in order to recuperate the gold plating from Connectors, Components, PC boards.
Some of the neat things that I actually remember buying
from there:
Ultrasonic motion detector boards, $1 or $2 CDN a piece
9" Phillips Green screen monitor $40 CDN (so other could watch TV while used my CoCo 3)
8088 Baby AT Motherboard (without ram) $5 CDN (when I finally decided to retire my CoCo and CoCo 3 and join the BORG^h^h^h^hDOS world in 1990.)
TouchTone(tm) keypads
pump and nozzle (from battery powered UZI Water pistols that were common in the mid 80s)
Medical Forceps and Clamps
80 Track Single Sided Double Density 5.25" floppy drives ($5 a piece) for use as a drive 2 and 3 with my Coco 3
A good selection of electronic instruments (scopes, hi-pot testers, signal generators, frequency counters, spectrum analyzers), some military stuff (radio sets, gyros, weird stuff)
Computer Party.
(I don't know if it is still in business) Brimley Road in Scarborough, opposite Scarborough
town center, just north of Ellesmere.
In the 90s, I bought a Tandy Model 200 for 40 Bucks.
Lots of older x86 stuff, some computers from the 80s, There was at least 1 old Electron Microscope there too though I never saw it powered up.
Sayal Electronics, Victoria park, just south of Gordon Baker on the Scarberian side of VP.
Some surplus components, used test equipment, power supplies, transformers, batteries.
I use my Palm III and iSilo (reader software available from iSilo.com) to read news and books (from Project Gutenberg) while on the bus. I also use it to store bus and train timetables.
Also, look into how much you would save since calls between you and your partner would remain in the same network or operator. Some operaters also offer friends and family type discounts.
I fall into the catagory of a GSM user with a fixed line at home. The fixed line is mainly used for Data and for longer calls. Nothing beats a mobile in terms of reachability (assuming you have good coverage, a charged battery, etc.)
Slides and Video.
