|
| |
ObHack: tuning a piano by yourself without a strobe or chromatic tuner. Use a reasonable quality portable electronic keyboard (one that you know is 'in tune' properly, or use a guitar tuner to tune the keyboard) and match the notes up by ear (chorus off for better precision). To deaden strings (so you only hear one or two at a time), cut up a large... more »

white board hanger
|
| |
/me needs a place to write stuff out sometimes, and paper isn't always big enough to fit everything so I can see it. Home office lacked a white board. Bought a decent sized white board (finally) for about $20 at a local Target (pens + eraser extra) but they didn't have an easel to mount it on.

mortise lock work

I did some things to it, removed some parts for features not needed (all I want is the doorknob mechanism, I lock the door with a separate deadbolt) and put it all back together. Things worked okay after that. A couple of years after that fix I... more »

In the spirit of the new year and the thread lamenting the lack of alt.hackers posts, here is one minor contribution. I have been using the same email (VM under Emacs) and news (slrn) readers for more than 15 years.

Is that it?

I must admit I don't look here often, but did alt.hackers just go 0 for 2010? So sad. obhack: Lots of script kiddies attempting to open /setup.php on my web server. Seemed like a great place to put a script to log the IP addresses so I can break their routing (my less than elegant means of banning them... more »

Lost RAID

Not sure if this counts as a hack but seeing as this group has been dead for an age.. Client has a Dell Storage array, 10 hot swappable disks in a shelf which is split so 7 slots are assigned to one SCSI port and the other 7 are assigned to the other port. Each port is attached to a different server,... more »
