Motherboard + RAM

Do any of you happen to have an old motherboard + RAM + CPU which you don’t need any more?

I need something reasonably fast, Intel or AMD, with PCI slots. It is going to go in my MAME Cabinet and hold an AudioPCI running the fabulous DOS driver (thanks, !) and some flavor of MAME.

Really, I’m not too picky as to what it all is, so long as its reasonably quick and free. :D

WTF?

Ever written a bit of software, looked at it the next day, then not been able to figure out what the hell you were doing?

If I didn’t somehow forget to save after the last compile, it looks to me as if the odd captured data from last night is complete garbage, because I was feeding the SPI data straight into the MAX232. That… I don’t know how I could have gotten that wrong.

SSH Scanning

Anyone else noticing a lot of SSH scanning going on?

There just seems to be a whole bunch more lately, with most of it happening overnight. That is, 9pm – 3am EDT, 12am – 7am EDT, etc.

Now that I finally got DenyHosts working properly things seem to be a bit better. (I’d stupidly bolted on to a default hosts.allow which had an ALL : ALL : allow up near the top in the comments, which I didn’t read.)

I’m up to 650-some blocked hosts, and I’m fairly sure there will be another 10 or so today.

On The Edge

Well, after a few months of on again, off again, waiting for carryout, eating lunch, toilet, and bathtub reading I finished On The Edge: The Spectacular Rise and Fall of Commodore.

It’s quite worth reading if you have an interest in the history of Commodore / Amiga and are curious about where things went wrong. It assumes a fair bit about ones’ technical knowledge, just diving in and occasionally talking about how / why some decision or another was bad, but it’s pretty easy to read.

OS X 10.5

So… 10.5.

To start: Finder no longer sucks. I’m copying 85,000 files (old maildir archive) and it’s behaving as one would expect.

I’m having some weirdness sending photos over from my phone via Bluetooth. Not sure what is to blame yet.

New Terminal is interesting. Not sure if I prefer it or iTerm more, but the concept of building profiles which affect everything the old terminal could do is great.

Mail.app 3.0 seems nice. We’ll see how it does incorporating my old mail.

Stacks are excellent, particularly when /Applications is added as one.

Uhm… More later. Right now I’m particularly waiting for my music library to start copying back so I have stuff to listen to.

Disk Shuffling

So, I think with the install of OS X 10.5 and some potentially new-to-me 500GB hard disks I’m going to set things up as follows:

/Volumes/Alpha (320GB): Boot disk, OS, ~, iTunes Music, Apps, other normal stuffs.
/Volumes/Bravo (320GB): Photos, Misc Storage, 60GB (or so) partition for Bootcamp running XP, which will also be usable from VMware.
/Volumes/Charlie (500GB): Backups
/Volumes/Delta (500GB): Backups

Backups are things like sync’d copies of most of the home directories on rowla.nuxx.net, data from the other volumes in the machine, stuff from my work laptop, and various other things.

I’ll then have two external 320GB disks left over, and I think I’ll use those for offsite backups and backups of my parents machine and such.

The really nice thing about going to all internal disks is that there will be an overall power savings (no need to run external adapters), SMART stuff can be polled from all drives, there will be less noise, and I will (hopefully) avoid some of the external drive problems I’ve had with OS X in the past.

The VMware / Bootcamp thing should also be nice, because then I can have just one XP instance available virtualized for normal use (development work, Quicken, etc) or full speed, running natively if I want to play some games. With the VM essentially having its own spindle it should run quite quick as well.

rowla.nuxx.net Problems

Oh boy. I don’t need this now:

c0nsumer@rowla:~> dmesg
[...]
ad0: FAILURE - device detached
subdisk0: detached
ad0: detached
GEOM_MIRROR: Device hotbackup: provider ad0 disconnected.
c0nsumer@rowla:~>

No SMART warnings, nothing. On Sunday the disk reported a clean healthcheck with 17970 hours of power-on time. ad2 had 24195 hours reported in the same log file. I’d expect it to go soon, too.

Thankfully ad0 is one of the first two disks on a secondary pair of disks in the box which aren’t critical. I first copy backups to those disks then copy them from there down to my house each night. Having half of that mirror set gone isn’t horrible, but I’ll have to take care of it at some point.

Maybe I’ll just throw one of the 320GB disks I have here on there in its place and finally get around to moving all my backup drives here internally. Time to check prices on new disks at Newegg I guess.

UPDATE: For $120 I can get a 500GB Seagate which would go nicely in my Mac Pro as a backup volume. I could then use one of the 320GB disks it would be replacing it as the hot backup in rowla.nuxx.net. I’d then have a spare 320GB I could leave attached to the Mac Pro via the FW800 enclosure, turned off, as an offline backup of photos.

Or I can leave it and wait until the other half of the hotbackup mirror set (ad2) falls over. The replacement 500GB disk will probably be cheaper at that point and it’ll require no work to be done right now.

This will be decided tomorrow.
