dinner before meeting!
by D. Hugh Redelmeier 13 Apr '17

13 Apr '17

Stewart almost suggested this last month, so I'll propose it this month: Doner Kebab House 391 Yonge St. (East side, south of Gerrard St) <https://wiki.gtalug.org/pre-meeting_dinner#doner_kebab_house_turkish> <https://www.openstreetmap.org/node/3708420193> (Notice who put it on the map.) I thought that the place had closed to be replaced by condos but they still answer the phone. Backup: Ramen Raijin at 3 Gerrard East - <https://wiki.gtalug.org/pre-meeting_dinner#raijin_ramen> <https://www.openstreetmap.org/node/2454474820> (Look at when this was added to the map.) Time: 18:00. Bring cash since DKH does not take credit cards.

File tagger
by Christopher Browne 12 Apr '17

12 Apr '17

I'd alluded to a "file tagger" last night... Here's the one I was aware of... https://github.com/oniony/TMSU It sets up a SQLite database in a .tmsu directory, and allows attaching metadata via labelling files. The metadata lives in the database, separate from the files, so it has certain aspects of, erm, fragility. Furthermore, they've got a neat extension whereby you can mount the database as a filesystem via FUSE so you can explore the tags looking for files. Unfortunately, that has a strong propensity to fall over leaving the special filesystem pretty mussed up. So it's more interesting as a concept than as reality. Neat idea, nonetheless... -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"

Hardware Hack - help needed
by Giles Orr 12 Apr '17

12 Apr '17

I have a deceased Thinkpad 340CSE. I'd like to use it as a shell for a Raspberry Pi (the case has a lot of space). The original keyboard is a thing of beauty by modern laptop standards, with several millimetres of movement and a good feel - so I'd like to use it if at all possible. Unfortunately, a lot of searching has sent me repeatedly to a page on how to convert a T60 keyboard to USB - different keyboard, different connector(s). There's a full explanation with photos here: https://www.gilesorr.com/blog/thinkpad-retrofit-1.html If you have any suggestions, feel free to let me know on or off list. If you think I need to add more information to the web page, same thing: let me know. If you know someone who might be able to help, please forward this to them. Thanks! -- Giles https://www.gilesorr.com/ gilesorr(a)gmail.com

> Back in the days of the Commodore PET, I wanted to convert the keyboard >> into Dvorak layout. Nowadays, I'd find the keyboard translation table, >> edit that and blow a new ROM. > Usually keyboards are wired as a matrix with the lines in the cable representing the X and Y scan lines and each switch at the junction of a pair of scan lines. The output scan lines have resistor pullups so they are normally all in the high state. One set of 'input' scan lines (say X) is then sequentially made LOW and the other set of scan 'output' lines is read in and decoded. When a switch is closed, one output line will go low when some specific input line is activated. This scan operation can happen very fast, so the keyboard is repeatedly scanned at 60 times a second or faster. (This matrix arrangement minimizes the number of required connections to the keys.) Then a computer decodes the XY coordinates into a key code. This would not be difficult to do with an arduino type processor: you'd use the output parallel port lines as the keyboard output scan lines, and another parallel input port as the input scan lines. Send the decoded information out the Arduino usb port. We used to give this to our EE students at Ryerson as an exercise in assembly language programming.

computer to a good home.
by Alvin Starr 06 Apr '17

06 Apr '17

I was using this system as a file server for a number of years. The motherboard is a Asus SLI/KFN5-D with 2 AMD quad core Optron CPU's with something like 12G of ram. It also has a 3wear 8port raid controller with 8 SATA cables. The motherboard and case are ok but the power supply had a problem and in trying to fix it managed to fry the drives and drive enclosures. There are 2 4 drive SATA holders and 5 drive SATA holder but unfortunately the back-plane electronics look to be fried. If someone wants it they are welcome to it otherwise it will be going to the recycling dumpster. -- Alvin Starr || voice: (905)513-7688 Netvel Inc. || Cell: (416)806-0133 alvin(a)netvel.net ||
