Also, the machine runs more then just my media center (webserver, subversion repository, backup jobs) and none of those crash.
Here I am probably posting too late to be seen. Anyway.
I can't help but notice that one class of software, that being computationally non-intensive, relatively little memory access, etc, works great, and the one specific piece of software that absolutely thrashes the CPU and memory crashes... So if you hadn't replaced your hardware this is where I'd have started, run memtest86+ on that dude overnight, maybe bonnie++ to exercise the I/O the next night, see what errors are reported. Thermal / overheating problems?
I see you've replaced all the hardware but the tuner, and it still crashes, which would seem to isolate the problem to that one specific piece of hardware. Flaky USB cable? Connector? Who knows.
There has historically been USB flaky-ness in Linux. Many years ago, I had kernel crashes merely transferring lots of files on a tiny flash drive. But last week I transferred 500 gigs off a hard drive in a USB enclosure no problemo whatsoever. You can see if there is USB weirdness by a similar scheme. If you can't transfer 500 GB of video MPEG data without crashing, maybe its a kernel USB problem.. try to transfer 500 GB of any USB data to compare... Try sticking an "old" 500 GB drive in an enclosure, "dd if='whatever usb device as seen in dmesg' of=/dev/null" and see if it crashes. Run it a couple times?
I have had some success with my truly ancient PCHDTV card... A bit out of date, not sold anymore. But I only paid like $75 for it when it was brand new, back when dinos roamed the earth. Probably its great great grandchild the PCHDTV HD-5500 would work, its current hardware, and its about $100. Or sometimes "new and improved" isn't necessarily so good. I'm sure an hour with google would leave you as a very well informed buyer.
Did you try a purpose built distro? My experience has been quite the opposite,
And my experience is the opposite of yours, in that big generic distros like Debian and its downstreams like Ubuntu have a large staffing advantage in fixing the problems that develop. Also distros like Debian are install once, upgrade forever. No need to wipe the drive and restart from bare metal when upgrading like other OS, or when the purpose built distro's developers evaporate away. And better security support, important if you make the system available over the internet (remote programming, etc). And better integration with other software, such as setting up gnump3d to serve up my mythmusic directory was about a 60 second job. And better utility set, I use unison to sync my media files across all relevant machines, don't know if thats even available on a small time purpose built distro. And better choice of support programs, I use munin to monitor all my machines including the myth boxes.
I suggest you try 0.23 as most of your concerns have been addressed.
Except for the hardware problem that makes his backend crash. I know its a hardware problem, not software, because I've been doing what he claims can't be done with the same software, for many years on multiple sets of hardware.
Most likely outcome is he upgrades the software on the crashy hardware, notice it still crashes, and post to slashdot again that the myth software doesn't work.
Instead, you have made a select group of people very rich and very powerful. Was it worth it?
Well, since they also happen to be the ones in charge of almost everything, I think they'd say yes. The lower classes are too busy drugging up and watching TV, and the middle classes are kept busy with B.S. distractions like "gay marriage" and federal vs state control of abortion. When Bush/Haliburton said "mission accomplished" they meant it literally. Just not the mission the gullible thought it was.
1) Some folks loudly and publicly claim birth control devices can't be used to prevent pregnancy because in the heat of the moment they are too inconvenient. Personally I think those people are making mating calls not accurately describing others. Regardless of who's personal life they're talking about, they'll use the same anti-marketing on this device.
2) STDs rates probably trend toward the stupid, addicted, and poor. Not exactly a marketing droid's dream. Giving them to unmarried people for free will get the loudmouth neo-puritans whom run the USA all twisted up. Could probably sell plenty to nervous people whom almost certainly are not infected, but from a public health perspective those would be wasted.
3) Dumb reactions. Thankfully most STDs aren't fatal, but you'll still have endless idiotic reactions to positive results. Can't catch it on the first try. Spray some bactine or windex on it and that'll prevent it. I suppose they'll be an increase in "heat of passion" murders when the spouse fails.
Yes but the embarrassment of whipping out my "three-inch-long bio-detector" and then waiting "just 24 hours" for the results before continuing is going to ruin the mood. Oh you meant that kind of eating out. In that case I apologize for the worlds geekiest "your momma" joke. On on "Mothers Day" no less.
If you're running a censored local or national Internet that depends on injecting falsified DNS responses, it's bad.
Fixed that typo for you. Note that it has little to no interaction with IP-level blocking or "semitransparent" web proxies, don't worry, China can still oppress their subjects.
Another attempt to solve things in a hierarchical way that should have been rather fixed with p2p web of trusts
False dilemma. You can do both at the same time. BGP IP routing on the net overall is vaguely hierarchical in regards to whom pays for transit and whom peers for free, but is vaguely p2p web of trust in that the DFZ pretty much trust each other to share good routes, or at least folks trust each other at carrier hotels. Some carriers trust some of their customers so much they're practically peering, in that they don't filter their "customers" advertisements, some not so trusting. Whats more P2P than an IXP like MAE-EAST, MAE-WEST, etc, where you trust your BGP peers not to screw up (and they occasionally fail you, of course)
If you want decent precision with a minimum of effort, why not use a Dremel tool?
Butcher. Put it in the vise on my CNC milling machine, conversational G-code at the keyboard, accurate to about a ten thousandth of an inch in a fraction of a second.
I'm sure someone richer than me would use a lasercutter, which even rounds the edges nicely.
A ".kids" domain would be a better choice, where you are voluntarily naming your content as child-safe, as there's unlikely to be a push to force you into that category above and beyond your own desire to be there.
Until the first lawsuit that demanded women with suntans, showing their faces, or bare ankles either be forced into or forced off of.kids either inside or outside of Islamic nations.
Also the first lawsuit in favor of or opposition to anything vaguely sex education related.
Also the first lawsuit in favor of or opposition to anything vaguely religious. For example, personally I don't think the bible is acceptable reading for small children due to the sex and violence, and the distinctly anti-multicultural outlook. Its at least rated R in my opinion. Not that it doesn't have value for adults much like an R-rate movie, just inappropriate for children.
#5 was a good try, but weak. The problem isn't the majority Christians but the fringes... Moslem women showing ankles, or their faces, or having a suntan belong, according to them, in.xxx
It's gambling with other people's coastlines, they're willing to take that risk if it means a more profitable well, simple as that.
Don't forget that a regulation applied to all companies merely increases the cost of everyones oil. Its not like anyones profit will change.
Whats more destructive, a bit of oil on the coasts of a major drilling site, or doubling the cost of petroleum... There is a fair argument that we're better off with the occasional leak rather than committing economic suicide...
Put another way, you can invest that money in solar panels or in unused relief wells, which is better?
Now implementing the "brazil rule" in the GoM, that would be interesting. Brazil Petrobras used to force drillers to activate the BOP on a live drilling string... chop clean thru that baby, live. That might be a reasonable middle ground. Knowing this BOP worked in a worst case scenario is a better (although more expensive) test than the kind of tests they do now.
in order to relieve pressure on the main well in the event of a blowout
Journalist interpretation alert! That would be a pretty useless plan of action.
How it actually works is they pump heavy drilling mud down the second hole faster than the main is leaking and obviously at a higher pressure. Thus filling the main with heavy drilling mud, shutting it off. This works; obviously the well didn't kick when it was being drilled, while it was full of heavy drilling mud, it kicked while it was empty/being pumped out at close up time. Once the well stops venting you pour even denser cement in, and wait for it to cure undisturbed. That permanently closes it.
Pressure creep. A gross estimate is about a PSI per foot of well depth. Its unlikely the actual pressure at the bottom of the well could exceed 20K PSI. Whats squirting out the top, order of magnitude less. Maybe, extreme cases, you can go plus or minus 50%, maybe. So, people whom know what they're talking about, knowing the drilling mud was around 18 pounds per gallon, and roughly how deep the well is, pretty much know how much pressure the stuff is boiling out of the well. However, the breathless journalists and political hacks feed on each other and one up each other for dramatic reasons. The wildest screamers blew thru 100K psi about two days ago, and I think we're well on our way to nuclear fusion pressure range in journalist-land.
Flow rate creep. An entire modest oilfield might produce 100K barrels per day. Real flow rate out of this well is probably in the range of 2K to 10K bpd. The screaming journalists and hacks recently blew thru 60K bpd, some beyond 200K bpd. We are rapidly approaching the point where the journalists-types will report figures better suited to the entire production of the country of saudi arabia, etc.
Unit changes. The flow is probably a modest 5K BPD. That doesn't sound as cool, so a couple days ago the journalists switched to gallons per day. As the flow decreases, I expect the screamers to switch to pounds per day, finally maybe milliliters per day, just to keep the numbers up.
Flow rate exaggeration. 5K BPD is like a firehose, vaguely. Journalists, over the past few days, have worked their way up on top of each other from adjectives like "dribbling" up to descriptions more in line with a Saturn-V rocket motor at full blast. Its going to flutter the "dome" around like a garden hose hitting a gnat. Uh huh, Yeah right.
I don't understand why they can't just bury it under 100 tons of concrete.
I see you're modded as funny... Serious answer though is the bottom of the GoM is pretty much just muck/slime/goo. It'll just bubble out via the next easiest path.
Ironically, the currently winning theory at the oildrum is the blow out was caused by a cement failure. Something down there doesn't cement-seal very well, so the simplistic solution of dumping more is possibly not the best engineering solution.
Does't the oil business have contingency plans for this kind of thing?!
Ummm, you'll notice they're working like an anthill stirred up with a stick, not exactly sitting around posting to slashdot all day waiting to decide what to do. You can accuse BP, the drillers, the Haliburton cement crew, the govt, and others involved, of many different things, but not having a plan and implementing it at warp speed is just not an educated accusation.
To make a very long story very short, oil naturally biodegrades over time by water internal-chemistry organisms, not oil internal-chemistry organisms. At a rate directly proportional to the surface area of the drop. Giant "ball" of oil the size of a football stadium will take much longer than a nearly infinite cloud of little microscopic droplets.
If a life form existed on earth with oil based protoplasm rather than water, you wouldn't need the dispersant because that life form could live inside the volume of the oil as opposed to upon the surface...
Think about bio sources of oil in the ocean. if there were no way to degrade oil, the oceans would be full of cod liver oil and whale oil. Similar with natural seeps of crude.
Much like radioactivity, crude is mostly harmless when properly distributed at an extremely low level in a large volume... its concentrated stuff thats the problem.
Those classes were also a complete waste of my time.
Ahhh, but the school got your money... follow the money, then you'll understand the reason why the world finds all schools equivalent, but schools have arcane transfer requirements.
I had a similar experience taking calculus four times at four different schools.
You make a good point, but what are you going to do about the students who are motivated and intelligent enough to pass a class without attending class?
Even worse, the school makes more money by forcing classes than by testing out.
In a travesty of justice, I had to take 1st semester calculus in high school (skipped a grade, long story) and at a community college to get my A.S. degree (not worth the paper its printed on, however), and at a state university that I transferred out of, and finally at a private college. All because 1st semester calc never, ever transfers. I am not kidding, this was my life.
In a way I didn't mind taking calc for the 4th time, because my employer was tuition reimbursing me for the full cost (back when that was possible) and GPA always likes an A+. It was kind of ridiculous to go from a somewhat below average calc student in high school to basically writing the answer key to each test at the private college. Calc really is simple, the fourth time around.
The only exception I can provide, where attendance should be mandatory, is my chemistry lecture used to end with advice for the upcoming lab. You can kill other people in chemistry lab, if you completely screw up. Better to have the 90 year old American professor lecture the kids about safety rather than the foreign definitely non-english speaking TAs. I never understood a word my quantitative chem analysis TA said, but I still got a pretty good grade. That the professor felt the need to instruct us about the TA's lab, would indicate he may have known something about his TAs language skills and sympathized with us...

In the United States, software piracy remained at 20%, the lowest level of software theft of any nation in the world.
I'll try harder to get my percentage up for next year, okay?
What happened is that Mandriva could not out-compete Ubuntu when it came to user-friendliness, probably because
Ubuntu is based on the superior Debian distribution and Mandriva is a Red Hat based distribution? And Debian is a lot more active than RHAT?

I can afford it. No return hassles. No sales tax. No need for a warranty. No elevated expectations. Can they do this with Windows?
Did that years ago, at piratebay.
Actually an at home STD test kit isn't a bad idea
I think it would work with three problems:
1) Some folks loudly and publicly claim birth control devices can't be used to prevent pregnancy because in the heat of the moment they are too inconvenient. Personally I think those people are making mating calls not accurately describing others. Regardless of who's personal life they're talking about, they'll use the same anti-marketing on this device.

See wikipedia "Bile" entry... Similar concept but in an ocean rather than the guts.
