Indeed, as I could have told you or you could have learned from their website. I suggest you take a look at their description of how they pack their disks in and you will understand the heat issue I mentioned above.
What's the typical drive temperature in Backblaze's cases in their environment?
They are not saying apart from an entirely useless average for machines that are idle a lot of the time with drives spun down. I'm not entirely sure they know or care what their maximums are and how long drives are hot for. I suggest taking a look at their web pages that describe their pod designs to get a better idea of the situation instead of just taking my word that they shove drives in wherever they will fit without taking heat into account. Given their workflow that's not as stupid as it sounds but there are going to be some times when some drives get very hot due to a lack of airflow.
Backblaze has redundant servers. It's the only way their "jam drives in where they will fit" pod designs make sense. At max load most of those drives will still be idle. IMHO raidz2 is a better idea but it's not what they are doing.
Not exactly. Take a look at their web page and their "pod" design. They have jammed in drives where they will fit but they have very different loads to a normal data center so can get away with it most of the time. Unlike a normal data center they will never be running all the drives in a "pod" flat out so something that would be a smoking mess elsewhere merely has drives in the middle that cannot shed heat properly. That's not to excuse Seagate, it's just to point out why failure rates are higher than what the rest of us experience and probably with a different mode of failure as well.
Yes but if the drives are failing due to heat it's not really useful information for someone else with file servers with very good airflow. Their results should be taken as an strong indication and not 100% reliable unless you have a situation very similar to Backblaze.
Perhaps they don't keep the temperature as cool as they should in order to save a few bucks?
They have a few things about their "pod" design on their website and if you look at it you will see that you are correct. It looks like an utterly insane design until you consider that the things are mostly idle, so typically don't generate a lot of heat, and that they have distributed servers with distributed workloads so they can afford to lose one entirely for a while.
I also wonder if we'll ever get numbers from Backblaze on things like the actual temperature
We got some numbers earlier from another story but they were entirely useless since they were average temperatures on machines that are idle most of the time. Maximums could tell us something useful. I won't bother linking to the earlier story because it was like a high school project. If it wasn't for their niche use of distributed archiving where their machines are unlikely to get very hot (but possibly individual drives would get very hot) I'd call their server design a high school project as well, but it actually makes sense for them. If a disk dies they can just shut down the server it is on, drag it out of a rack and dig the drive out of the middle of the "pod" out from under all the other drives without impeding their operations. They can afford a lot of server downtime just to replace single disks because others server have copies.
I've got a large cardboard box full of dead Hitachi drives for some reason, along with a smaller number of dead Seagate drives. I've stopped buying both. Maybe I just have less dead Seagates due to being turned off that brand earlier.
If it's working for them in their packed in boxes with crap airflow and really poor heat transfer then it will work even better in conventional file servers with hot swap drives at the front and a heap of airflow.
Take it with a grain of salt when Backblaze say a drive is crap since it may only be crap in their very hostile environment, but if they didn't break it then it's very likely to work well anywhere.
Readers the post above can be better understood if you look back at his earlier posts about world government control and how 9/11 was a hoax. His bits about the Pentagon crash being entirely faked with no aircraft involved and a building being deliberately blown up (instead of being burnt down due to thousands of gallons of fuel splashing about) will especially enlighten where he is coming from.
He used his HR granted title of "engineer" to a leading hand in SOFTWARE with no project to lead and no subordinates as "proof" that he knew about civil engineering and that steel doesn't get soft in fires. His lines above such as the following make perfect sense in that context:
The proposed cure for Global warming is to massively tax the populace. No plans to clean up, no infrastructure to replace what gets lost in massive taxes, but a few people sure as hell get richer
He's pushing a very strange agenda with no reference to reality.
You literally can't think of a better solution to dictatorship than condemning everyone you ever know and yourself to eternal oblivion of death?
It's actually pretty damned good to have people who think they are God incarnate have someone whisper in their ear to remind them that they too are mortal. Do you have any better ideas?
Has it ever occurred to you that in a world where most people expect to be around in a few centuries, and for the foreseeable future unless a big war or planetary scale disaster happens, might be a world where wiser, more long sighted decisions generally are made?
While a know a couple of geriatrics that are very wise they could have been called that at 40 and the majority of the old are just as stupid as the majority of us in a different age bracket. I'd say take a look at Iran for that future you think you crave. A tiny elderly minority are running the place where the average age is in the twenties and the elderly are the warmongers with some pretty fucked up ideas that they can not adapt to a changing world.
You do realize that aging related intelligence decline would have to be fixed
That's not just a goalpost shift it's moving onto a different playing field.
The Canadian-German TV series "Lexx" had that as well in the first episode, but in that case the perverted meme was perverted even more when the harvested organs were not used for implants but fed to an organic machine. Dick Cheney kind of reminds me of the villain running the ATF in a parallel Earth near the end of the series, played by Malcolm McDowell.
If you were 18 and could fund college by selling blood, would you
Back then I gave it away. Having a price on it seems a bit perverse but I suppose some places do not have their health system up to scratch or don't have people willing to donate and have to pay for it.
From what has been written he's playing around almost at random instead of doing things in a way that can provide answers. Not science. Sympathetic magic. I think we'd all be better off if he was playing golf or if he funded professionals to do something or learned how to do things in a systematic way himself.
Neither has he which makes is a creepy belief in sympathetic magic (look it up if you don't get how aptly this term describes the situation). It's also a bit of a worry that so many people are using the word "research" to describe looking something up that has actually been researched by others but I suppose that's the new common usage.
There are too many variables in what this guy is doing to consider it in the same room as science or even logic. If he lives longer then which person's blood did it and what is it about that blood that did it - no way to answer it from the way he is doing it so it's a desperate and somewhat pathetic search for magic instead of actually learning anything useful.
When I read stuff like this it makes me happy that we all have a use-by date and will be replaced with others with different faults instead of the same old idiots ruling forever.
Bullshit. Reagan had decades of experience of treating every microphone as live. It was a joke obviously delivered deliberately to an audience to make Reagan look "tough". It really pissed off a lot of people because it depended on drunken people in the fractured Russian leadership with English as a second language hearing it as a joke - though the risk of anything happening as a consequence was close to zero if not actually zero.
See how a comment about "we will outlive you" being spun as a deadly threat going in the other direction to get an idea about how the joke pissed people off like a roast pig in a synagogue.
It was deliberate and "sending a message" to get people angry and make Reagan look really tough at home. The "thought the mike was cut" thing is utter bullshit from gutless weasel apologists and the joke never would have been taken seriously anyway. The saying about making sausages and making politics being very ugly to watch applies very much with that petty incident.
PayWave is awesome.... I've learned from past experience to have 3 credit cards: 2 in my wallet, 1 at home, that way if one gets compromised I have options until I get a new card
I think it's a guess for a quick theoretical example. My guess is they wouldn't take anything that could be blocked but I don't really know either.
To paraphrase a comic I roughly remember: "You'd even give the vote to soiled doves?" "It would help with economic policy. Cerberus has never met a whore who would abide credit."
Those fraudulent charges can max out the card and prevent you using it or getting a new one until you have managed to convince the bank they are fraudulent charges. Apparently quickly dealt with by some banks but weeks with others.

Good point, Malcolm McDowell played a different character earlier in the series.
Indeed - which is why I wrote "From what has been written".
I suggest reading a bit more and/or getting out a bit more.
You'll understand why there is the saying "it takes a village to raise a child".
Wake me up when it's finished and usable instead of a total mess with two control panels and a requirement to search instead of navigate a menu.

If it's "risk-free" why your post above about multiple cards to mitigate the risk?
Not exactly selling the idea well there.
