The 7200.11 debacle! It was unbelievable that it happened- as far as I remember, Seagate was the leader in reliability before then, I had created five or six RAIDs with Seagate drives with 100% reliability.
But when they released the 7200.11 versions....ALL 7200.11 models would spin down after idle for X minutes and then start clicking...the data was still intact, but for the drive to work again you had to pull the power.
I unfortunately built an eight drive RAID5 with these drives before the issue was know, which made it very difficult for me to diagnose the issue. (All drives seemed perfectly fine when powered and working for the first 5-10 minutes or whenever they were in use, but as soon as a single drive of the RAID idled, the RAID5 acted like a drive was bad).
I still have a box with eight 1TB Seagate 7200.11 drives that I never updated. I have never bought another Seagate drive for RAID since, always WD or Hitachi.
Yup. I had built a gaming/workstation desktop using 2x 7200.11's in RAID-0. It started acting up, at a lan party of all things, which made me suspect the RAID controller on the motherboard, especially after using the drives separately seemed to work ok. But then one of the drives died and then the other, both at pretty much the least convenient moments possible.
Nope, seen many examples of this recently (but I'm a web developer, and we usually pass around links to the latest and greatest). Of course, I can't think of one off the top of my head now...
Actually, it's not very water soluble at all. It's a large cyclohexane that's relatively non-polar (the first comment in that reddit link agrees). Approximately 5000 gallons of the chemical spilled into the river, so there likely isn't very much of the chemical mixed in with the water. Most likely not enough to seriously harm anyone.
It's not insoluble, it is up to 3% soluble. "Most likely not enough to harm anyone." For some reason the state has declared it a federal disaster?
check out this green ice- look, it's not soluble! Fine to drink! http://i.imgur.com/pzBsLRP.jpg
Its solubility maxes out at 3%. ~5000 gallons in a river is hardly enough to get to those levels. The news is reporting that the concentration is about 3ppm. 3ppm of 4-methylcyclohexane methanol is about 0.021g of the chemical in 1L of water. The lowest LD50 for ingesting the chemical I've found is 800mg/kg. This means you'd have to drink 3086L of water for it to be lethal. The LD50 for skin contact is at least double the ingestion LD50.
That being said, I'm not going to take the risk, and I've only used water out of water bottles since this started.
Sghodas- I think you are missing the point. By your math and 'rational' it seems there shouldn't be an issue. This spill was not some homogeneous mixture you can easily calculate in PPM. This chemical has travelled wholly through the water plant into the water supply- solubility doesn't matter. Two to seven days have elapsed between intake from river, through filtration/ozone treatment, to holding water tower, then into public use. How many PPM do you think are in the green ice cubes someone found in their freezer? And at what PPM does ingestion cause long-term health effects?
LD50 is fairly useless as it gives no indication of the toxicity of lower levels of the substance. It takes a large volume for some chemicals to kill you, but a much smaller amount can make your life very unpleasant.
The "68" recording had me wondering if this was a real person, which was terrifying. Some people have been saying this could be a soundboard operated by a person, which does seem plausible. I probably would have said Cirrus, Socrates, particle, decibel, hurricane, dolphin, tulip.
Only it couldn't because that's not even close to what the article was saying.
It was pointing out that looking the part gives opportunities which might otherwise be closed. Therefore spending your meagre savings buying fancy clothes can be seen as an investment.
I'm not addressing the validity of the article's point vs yours, but the summary was not correct.
Unfortunately I don't have access to that particular configuration; if you or anyone else has any ideas as to why it crashes we'd love to hear them here or over at the Github page!
