it's raining.. bitcoins?!?

Worked a lot with my new bitcoin mining rig this weekend.  It's running pretty smooth and trending around 800 mhash/s.  I've got another nice fan coming tomorrow to improve the air flow a bit inside the case which should bring down the temp a few more degrees.  What's next?  It's an Ubuntu system, but I think my next step is I need to boot into windows long enough to unlock the bios limitations.  Generally this is useful for overclocking, but I'm actually looking to do the reverse.  I want to underclock the memory and voltage since I'm not actually using those aspects of the video card.  This will generate less heat, thereby allowing me to raise the core clock speed of the gpu.  The end result?  More mhash/s at the same temperature.  At least that's the goal.  We'll see how that works.  Not looking forward to putting Windows on the box though.. might just borrow a hard drive with Windows on it long enough to do the unlock.  Hmmm....

Is the pool open yet?

Is the pool open yet? The short answer, no.

At the start of the pool season I was on top of things. I got an early start, got the cleaning supplies I would need, started working. The waterways blue and looking good. There was just one problem. After a few days water started leaking out of the pool pump. *sigh*

Unfortunately I was afraid this might happen. The first big freeze last fall caught me by surprise and I had to do a rush job on closing the pool. I figured something would go wrong.

Back to the spring opening, water leaking out everywhere. I called around to the local pool shops. They either only deal with in-ground pools or they were currently booked solid with openings and were not accepting new customers. Damn.

I finally found a guy using google local search. Excellent! I gave him a call, explained the situation, and later that day he came out to take a look. After taking a look the pool guy said he thought he could fix the motor, he would pick up the part he needed and come back the next day. I tried working with the guy, he seemed nice and genuine enough. At this point he has basically disappeared with the money I gave him for a new pump (after the repair did not resolve the issue), and the phone number he was using has been disconnected.

I contacted a couple other local shops again and there's not much help to be found. *sigh* I give up. I'll figure it out. It's not rocket science or a complex software development issue. It's PVC pipe, some fittings, some wrapping, and a motor. Ordered a replacement pump online (1/2 the cost of what I was taken for locally) and I'll install the darn thing myself.

The pool WILL open. :)
