Does anyone have experience running UBUNTU Linux (or KUBUNTU with the KDE) and BOINC?
I see it's possible, and there seems to be some assistance in getting it working. I'm not a Linux guy, I have not had time to explore it, but I'm getting interested in creating a "cheap server" farm and getting the most CPU operations per dollar for things like digital video and TV, multimedia storage farms, and, yes, WCG. I have found that I can build a dual core 2.8 full system (DDR2/667, SATA 3) for $300 (or a 3.2 with double the per-core cache for $400) and I don't want to spend the $100 for a WinXP license on top of that. It's a SiS 662 chipset (966L southbridge with builtin video, lan, etc)... That means loading the SMP kernel, probably on the 6.06 LTS release, and I'm wondering if anyone's tried BOINC on the SMP kernel (and does it use all cores?) Cheers FB |

Brink, speaking of wheat, I just transferred a batch into the primary fermenter, and it is bubbling away nicely (fermenting). When it is finished, I will transfer it to a secondary fermenter where I will add cherries to make a Cherry Wheat. I'm anxious to see how this one turns out because I used regular bread flour for the wheat -- blended in with malted barley, so it isn't a true, 100% wheat. Had some minor problems with the sparge (filtering from the mashtun) because I didn't have any rice hulls to add, but took a chance anyway because I have a heck of a bazooka in my tun -- 10 feet long. A bazooka is stainless steel mesh tubing, taken from the outside of a reinforced washing-machine hose. Always works extremely well.
Fred, I know next to nothing about computer systems, so I can't help you at all on that end. Regarding mead, I've never made one -- just a melomel once, which is as close as I got. Do you boil your honey, too? ... because I was under the impression that this will cause it to lose much of its aroma. I figured that you would just pasteurize it and then add it at the end. I see that there are no hops, so gravity during the boil wouldn't be an issue in that regard. As for our team, we're still plugging away and gaining on Texas A & M, which is good because we're about to be passed by Marist College, and the Teddies are gaining on us, too. But I think we are pretty secure in the Top-100 for the time being. So long as too many don't come up from behind, there are still many ahead of us that we are gaining on. Thanks again to everyone for their contributions. Cheers. |

Fred,
It is a bit early in the morning for me, and the brain is still a bit fuzzy..... but I am pretty sure that ubuntu is based on Debian linux which is what I run at home on a couple of computers. Yes, all cores will run with the SMP kernel. Downside is that currently using a linux o/s will only return half the points for the same amount of results as you would running windoze. I believe that there are plans afoot between boinc and wcg to right this injustice, but at this stage you will be a bit disadvantaged.

It is a slow march through the rankings - but a march none-the-less.

96th -Brink Yes!!! I hope this weekend goes well with my systems, two of the three have stopped at some point in the last week for no apparent reason. I'm heading to SLC for some skiing and will not be able to babysit them!  Dave |

I see that there are no hops, so gravity during the boil wouldn't be an issue in that regard. The honey is pasteurized and a bit more, you're right, it isn't boiled for any length of time. If there is fruit to be cooked, it's done first in the water (any raw fruit has to have all bacteria, molds, and yeasts killed before fermenting it), then the honey is added. I prefer a raw (unfiltered and unprocessed) honey, which does mean some debris pieces and other removables. I heat the honey to about 180 and stir until the foam stops rising to the top, then turn off the heat. The only time I did a cold fermentation was with fresh pressed apple cider from a local farm. I'd purchased a gallon once before, and left about 1/4 of it in the fridge, forgotten in the back, for about 3 weeks - at the end of which, I ended up with the best tasting hard cider I'd ever had. So I purchased a carboy's worth, threw in a couple pounds of honey for flavor complexity (dissolved in the cider by warming it a bit) and a bit of corn sugar to prime the yeast. I've still got bottles after 6 years which are still the best cider I've had. In fact, I'm going to chill a couple for Christmas dinner. I know (from personal experience and reading) that cold ferments with wild yeasts can be hazardous, especially from commercial fruit presses. I have read that the nasty strain of E Coli (O157 H7) likes to live in that environment (transferred in from the feces of cows used as fertilizer for the apple trees). I hesitate to take that chance and brew another batch, since the toxins can still survive even if the bacteria are killed in the fermentation, but I still enjoy the one I (in all ignorance) made.

Just watch the blizzard on Sunday/Monday! cheers FB |

I believe that there are plans afoot between boinc and wcg to right this injustice, but at this stage you will be a bit disadvantaged. I hope that gets resolved soon, for the sake of all Linux users. That sort of disadvantage is really quite discouraging. Thanks for the info on Ubuntu. You're right, it's a Debian variant. Cheers FB |
