Interestingly they penalise you for short-term storage:

Amazon Glacier is designed for use cases where data is retained for months, years, or decades. Deleting data from Amazon Glacier is free if the archive being deleted has been stored for three months or longer. If an archive is deleted within three months of being uploaded, you will be charged an early deletion fee. In the US East (Northern Virginia) Region, you would be charged a prorated early deletion fee of $0.03 per gigabyte deleted within three months
The only issue I see is that verifying archive integrity (you don't want to find out the archive was bad after you lost the local backup...) would be somewhat complicated, given their retrieval policies. Also, the billing for data-transfer out plus peak retrievals sounds so convoluted, I can't begin to work out what a regular test-restore procedure would cost me. Nevertheless, it's some exciting progress in remote storage!
To be fair, if improvements in hardware and software continue at the rate they have been, or some moderate percentage thereof, in 100 years it will be no problem to trawl a few exabytes of data for anything interesting.
Regardless of that, it still makes no sense to time-constrict a websites uptime. It's not as if websites run on manual labour! (well, it takes some to create one)
He's talking about the principles of psychology and escalation of anger. Studies show that when you actually hurt someone, your brain devalues that punch and makes you think you didn't hit very hard, but when you get punched your brain blows it out of proportion.

I'd guess that they ignore that problem and have baked the time it takes to get data from several tapes into the 3-4 hour estimate.

If you think about it, writes are more common than reads on average, so it's more efficient to just write to whatever tape is online and deal with the fragmentation problem on the read end, as opposed to queueing writes until the 'correct' tape can be brought online just save some time reading. Also in backup situations like this, it's more important to get the backup done in a timely manner.

Because this isn't reddit. Political stories used to be very rare here, as I'm sure you're aware, and that was a large part of the appeal.
What's even more important, you will be able to encrypt your backups without having to disclose the encryption key in case you ever need to restore (client-side encryption and decryption). This is not the case with Backblaze, which is why I switched to CrashPlan — but I'm still looking for other solutions.
Can anyone make sense of the retrieval fees? Seems like the most confusing thing ever. If I'm storing 4TB and one day I want to restore all 4TB, how much is it going to cost me?
Pure speculation: could be that poor kids were more likely to have dealt with similar problems or even just to have dealt with similar levels of suffering, and therefore respond with a little more short-term resilience.

Not like anyone can do follow-ups on this research any more.
There were a frightening number of children that were trapped in the old refrigerators. They often used them as hiding places and could not get out until they were redesined They had latches and even when there were interior releases it was not obvious to a child how to open it when in the dark and with limited leverage.
Even knowing a study like this would save lives I would find it hard to see it getting approved by modern ethics committees. It really says a lot about how our society has changes as anything. The society is much less Unitarian in its ethics simply sounding suspect is enough to get rejected.

Well, not if you interpret "stealing" as "misappropriating," but I don't think the quote is quite that literal. My interpretation of it is that good artists "borrow," that is, they take elements from others but they still belong to others. Great artists, however, "steal," meaning that they take elements from others and make them their own to the point where we start identify those elements with the "thief" instead of the originator. Someone who succeeds in doing that is probably a pretty damn good artist.

> Instead, the scientists designed a very small, rather dense, playhouse. It looked just like a normal kid's playhouse, except that it was the exact dimensions of the average home fridge. Not only that, the house was equipped with an infrared camera on the top, which took videos of the kid while they were inside, while at the same time keeping it dark, like it would be in a fridge with the door shut.
It should also be noted that the scientists teamed up with a psychiatrist, a child psychologist, and the parents to agree on the length of time the child would be allowed to cry before they helped it out. Three minutes. [1]

Hmm, three minutes of discomfort in a dark playhouse doesn't seem quite as bad as drowning or being burned alive. Especially when you consider the deaths that might be avoided as a result of the research.

i understand. i hoped tarsnap knew what blocks (do not) get reused.

it's unfortunate, because some backups happen to just lie around for very long. it would be nice to take advantage of (the low cost of) glacier for that.

that said, if it's not possible with tarsnap now, it's not possible now. :D. if you find a satisfying possibility to incorporate it in the new backend(s) design (if that's fixable in the backend(s) alone), i'd surely be pleased.
Oh, I absolutely agree that Glacier has lots of great use cases. I wish Tarsnap was able to make good use of it.
Yes, I use a custom class on my header that removes the rounded corners that appear on the navbar when you don't use the fixed class (don't know if it's still the same on 2.1).
Excellent! Is there any good open source client / backup application for this? I would start using it immediately. I'm currently using ridiculously expensive backup solution.

I agreed with him up until his solution. Because "controlling input" is also unsustainable when a community grows. Who is going to control input? If you're talking about HN, even Paul Graham tried to control input and it's not working. Or maybe he's not doing it enough.

Listen to the Mixergy.com interview with Paul Graham. At exactly 49:40 Paul says, "[hacker news] was originally called startup news but after 6 months we changed it to hacker news cause we got sick of reading about nothing but startup stuff." And yet here we are again, HN is nothing but startup news, I just gave up and joined in, no use swimming against the current. The sad part was that HN was originally a much better nursery to startups because all startups begin their life as a project, a hack, a mod, a solution. HN was all about code back then, which put off a lot of people who couldn't code (myself included) and slowly it turned into more startup news to allow for a larger audience.

The question is which came first?

Was it necessarily a bad thing?

How can PG / Should PG force the community back into more of a hacker culture than a startup culture?

I came up with an idea to control who the members of a community are by means of crowd-sourcing (http://www.chrisnorstrom.com/2011/02/invention-creating-and-...) but still, how can one control the hive-mind of the community to prevent it from wandering away from its original intent? We've seen what happens when one doesn't control the community. Maybe its time to play secret-dictator?
These are true statements about Python's strengths. I don't realistically see how those are going to help you get a job unless that job also takes an advanced degree, or at the very least a BS touching on a field you have specialized knowledge of.

You can always sign up to odesk and/or vworker and pick up some paid coding tasks there. You might even end up working full time (I have).
I've just graduated in Civil Engineering and many of my peers are seeking jobs in the industry (UK).

In terms of market conditions, you are quite right in that although volumes do fluctuate with economic conditions, work is always required (remedial work for example). Also, and I can only speak for the UK here, in tougher economic times the government often tenders large infrastructure projects to boost demand (think HSR).

The other reason civ eng is quite different is due to a high level of regulation and accreditation, in most countries you simply cannot practice (legally) if you are not chartered. This is one of the major factors that drove me away and into an industry where i could move much faster, with more freedom and lesser consequences (most of the time!!).

That's the thing, at the individual person level, everyone is always "looking at" moving to a lower tax area. They don't move.

> Glacier would be $10 a month for 1 terabyte. Fantastic.

+ the $120 or so per TB to transfer it outside of AWS if you need the whole thing back as fast as possible. Still likely to be very cheap as long as you treat it as a disaster recovery backup, though. Will definitively consider it.

(an alternative for you is a service like Crashplan, which also allows you very easy access to past file revisions via a java app and can be very cheap and also allow "peer to peer" backups with your friends/family; the downside with Crashplan is that it can be slow to complete a full initial backup to their servers or to get fully backed up again if you move large chunks of data around)

No sigh was necessary, I understand. I even mentioned that I have a NAS and off-site backup... so either you didn't read it all or you stopped the moment you encountered the word "Dropbox" and started typing.

That said, people DO use DropBox as backup.

If you take a walk around the British Library and asked every PhD student working there how they "Backup" their research and work in progress, I bet every single person who believes that they have a backup will say "Dropbox", and the only exceptions will be a few who don't really have a backup.

I know that because I ensured my girlfriend does have a real backup solution in place that is tested. Not one of her peers seems to.

DropBox is used for backup because they've made file sync so damn easy that most people can be convinced that if a file exists in many places, it is backed-up.

My whole point is that now storage for long term backup is priced in a way that is affordable to most, that consumer services may emerge that offer true backup to consumers and can successfully migrate people from lesser solutions (DropBox, stacks of CD-ROMs, etc).

One of the things about backup is that it needs to be easy. Currently the size and cost of backups make it expensive, and the only way to reduce the cost makes it difficult (HDD local copies stored at a friends' house for example).

By reducing the cost, perhaps we can finally increase the ease... and then a day may come in which most people have a real backup solution.

They store the last 30 days worth of versions of every file you modify. Dropbox could keep versions from the last 10 days in S3 but move the rest to Glacier. Restores for older versions wouldn't be instant, but if S3 storage is a nontrivial expense for them moving the bulk of previous versions to Glacier would cut down on costs.

Registration for Windows 8 Upgrade Starts
Home-use is probably the only situation Glacier is good for backup though.

A home user is fine with a 3.5-4 hour window before their backup becomes available for download (as it will probably take them days to download it anyway).

In a corporate environment, I don't want to wait around for 3.5-4 hours before my data even becomes available for restore in a disaster recovery situation.

Seems good for archive-only in a corporate environment (as the name implies).
Not necessarily. Plenty of commercial packages say "made for Redhat X.Y.Z".

The fact that something only runs on iOs means it's a fairly limited piece of software in terms of portability - which is an acceptable tradeoff for many things, but not for others.

Shall we stop there, or shall we test my claim?

You're missing my point. It's not about 'stopping there'. It's about robust observation. The best observations we can make are treated as correct until we can come up with something better. We used the known wrong model of the atom for a long time, but it was the best we had, and we learned a lot in doing so. Your "shall we stop there" argument is utter strawman nonsense, and not what I am arguing. Robust observation allows someone coming along later with better info, because it makes the observation more robust. I have no idea where you pulled this "stop as soon as a claim is made" crap from.

So you're saying that classification like taxonomy, the periodic table, and even SI units are 'not science', because these things are not due to a tested claim? If they're pseudoscience (as you are implying they must be, since they're all just 'claims') then isn't all science that uses them inherently suspect as a result?

Ideas must be compared to reality, and if reality disagrees, they must be discarded.

Which doesn't contradict what I said. Robust observation agrees with this sentiment exactly.

You're trying to paint me as a crazy pseudoscientist, but you're working from a faulty perception of what science is.

Here's another example: in medicine, there's a lot of work done on case studies for diseases with a low number of victims. It's just not viable to run double-blind studies with such low n, and repeat those studies until you find an answer. Case studies are a way of doing robust observation: "In previously similar situations, this was done, and this happened". It's not perfect, but it's a hell of a lot better than nothing. It's following scientific principles of do something, observe, report faithfully.

Similarly, the Mars exploration robots are out there looking at stuff for the first time. They are exploratory science. What would you have them do to make them fit your narrow vision of science - launch a robot into empty space to provide a control group representing the 'null hypothesis'?
Startups: Burn Fast or Burn Slow
Given it takes 3.5-4 hours to retrieve a backup before you can download it, probably not.
No, it doesn't.

Before you can design a bridge, you have to graduate with a four year degree in Civil Engineering. Then you have to pass the Engineer In Training (EIT) exam, then work for four years in the industry (helping with, but never actually able to sign off on, designs), then pass the Professional Engineer (PE) exam specific to the discipline you now have 4 years experience with.

Then you get to design your first bridge and put your stamp and signature on the plans.

So, with that knowledge, how exactly does civil engineering have problems with untrained entry level people signing off on designs for bridges that readers here are likely to drive over?
Great idea, have you got any more details?
I am 18. So yes, it was just a few months ago actually!

I understand it, yet I think it is an immature behavior. I believe it's better to be known for what you actually do and titles given to you by other people, than slapping a title next to your name.

Except when you bootstrap a startup, work nine to nine every single day for months and raise a million or two. Then you can probably say you're a CEO.
Well, it's an interesting topic.

I don't know why moss can't be (say) indifferent to its own growth. How does one know, other than that it seems to stand to reason?

It seems to me that even cute fuzzy animals are much more indifferent to things than people tend to be. Even people are often pretty indifferent when they are in slightly altered states, without fundamentally changing their brain structures. If I am totally ridiculously zonked on GHB and barbiturates and someone breaks my toe, I might notice that and still be indifferent until I dry up. The outrage only comes after I start making decisions and putting things together, otherwise maybe it is just something that happens.

Not that I suggest breaking bears' toes or anything.

It probably isn't safe to assume that the word "bozo" is applied in a remotely objective way. Or even that it has any kind of consensus definition.

So in any given case there is a good possibility that the "bozo detector" goes off mostly on people who don't like you, or whose lunches smell bad, or even people who might be competition, or people who are doing better than you are.

That's not really how I visualize functors. Let's go back to the function picture:

--- ---
|a| -- f --> |b|
--- ---

This is fairly simple--using f, you can go from a to b.

Now lets imagine a functor F (with f still being our function):

--- ---
|a| -- f --> |b|
--- ---
| |
|F|
\ /
V
---- ----
|a'| -- f' --> |b'|
---- ----

So a functor is just a function at a higher level. A function maps values of one type to values of another type. A functor maps types to other types. In Haskell, types in the Functor class always map types of kind * back onto * , so they're much like functions of type a -> a.

The crucial part to notice is that it not only maps between types but it also preserves functions. That is, you get new types corresponding to your old types and new functions corresponding to your old functions.

So the list type, for example, maps any type a to [a] and any function (a -> b) to ([a] -> [b]). In a sense, it is like a well-behaved function between types.

Coincidentally, thinking of functors like this is how I realized that functors in Haskell are not completely unrelated to functors in OCaml--they're just different reifications of the same mathematical idea.
