sata UMS

have to buy some disposable HDD for my mythtv cache... with the high prices of HDD i will buy one of those fancy usb3 enclosures, use the 1TB HDD that comes inside, and keep the usb3<->sata converter to use as a sata dock.

first, is it worth?

- the cheapest 1TB 3.5" drive goes from $75 to $200.
- usb3.0 enclosures with 1TB drivers goes from $69 to $140. averaging $80.

So, Price does checkout. it's even better than buying the bulky 3.5" drive!

- all regular HDD are 7500RPM, sata2-6gb/s, and have 32Mb~64Mb or cache.
- all usb3 enclosures are 5400RPM, sata2-6gb/s (counting the internal drive) and have 8mb~16mb of cache

The cache (32 vs 8mb) may make a big difference on accessing recently written files and random access of cached data. I do not expect to have such use case using the HDD as a mythtv cache disk. Also, performance of the regular drive is around 100Mb/s on sustained read and writes. the same reported over usb3 for the other drives. in fact, the same as reported on usb2 as well. the drive is the culprit.

7kRPM vs 5kRPM may make a difference in some cases, but again, for a mythtv cache writting/reading low bandwidth MPEG2 video steams, not the case.

So, performance does checkout.

Brands

brands. Previously i had nightmares with WD, and loved Hitachis. But hitachi sold in 2012 all it's SSD and 2.5" factories and brands to WD, and all it's 3.5" brands and factories to toshiba. So Hitachis are no more. Hence, i couldn't care less for brands at the moment.

simple rsync

How to use rsync logic to copy only modified/new files and not have to run any service on the other host.

basically you will have the same result/security/convenience as running scp
scp -r sourcefiles/* destination.host.com:/destination/

but with the added rsync logic:
rsync -r -v -e ssh sourcefiles/* destination.host.com:/destination/

usable tackaball

got a logitec usb trackman from ergo last week. really liked the middle style trackball, but missed scroll. the solution:

wrotenote-lx$ cat logitec_usb_trackball.sh 
#!/bin/sh
#                                              1 2 3 4 5 6 7 8 9
#xinput set-button-map "Logitech USB Trackball" 8 9 2 4 5 6 7 1 3
xinput set-button-map "Logitech USB Trackball" 1 9 2 4 5 6 7 1 3
#                                             LF  rt        lf RT
# LF = big left button
# RT = big right button
# lf = small left button
# rt = small right button

# liga emulacao do whell por movimento do mouse
xinput set-int-prop "Logitech USB Trackball" "Evdev Wheel Emulation" 8 1
# diz q par de botoes o movimento no eixo X "clica"
#xinput set-int-prop "Logitech USB Trackball" "Evdev Wheel Emulation X Axis" 8 6
xinput set-int-prop "Logitech USB Trackball" "Evdev Wheel Emulation Axes" 4 5 6 7

# apertar o botao 1 ativa emulacao acima
xinput set-int-prop "Logitech USB Trackball" "Evdev Wheel Emulation Button" 8 1



the buttons now do:
  • Big left button:

    • click for Button 1 (left click)
    • Hold for scroll on the trackball moviment (all four directions)

  • small left button: always button 1 (so i can drag things and select text)
  • small right button: Button 3 (right click) my least used button
  • Big Right button: middle click. I used that button a lot, to paste and thown windows to the bottom of my desktop zindex.
