It's called radiation hardening, there's many methods. Here's a pretty thorough paper about those used for the LHC detector:

One way is simply to use larger transistor, so that errors are more difficult to create in the first place.
You've got a point there, but shipping that book to where I live halfway around the world in New Zealand isn't doing climate change any favours.
I read that heat has yet to be proven to detriment a drive's life or performance within reason. Sure, 5000 degrees would be bad, but there apparently is no evidence that cooling drives matters.

I can't source the article, but seem to recall is was google related with the data coming from their experience with drives in their data centers. It possibly could have come from BackBlaze, though that is a distant second.

I used to run a small ISP, and found that I had a 10% failure rate on average of anything, before it was even used. Order 100 new servers, 10 will be dead on arrival. Order 1000 drives, 100 will be DOA. 100 network cables, all will work, that was about the only deviation.

With drives, the failure rates were better, however, I never allowed drives to be put into use that were not internally "certified". I would use SoftRAID, which is a Macintosh application, though I am sure there are equivalent on Linux and Windows. While this is nothing more than software RAID for the Mac, many of my servers were not Macintosh. I didn't use the RAID capacity of the software, rather using the drive certification feature instead. It takes about 8 hours per 1TB drive to "certify" it. This will run through every sector on the drive, and make sure it is ok. The softwares ability to "predict" that a drive was about to fail, or susceptible to failure, was very good. I would never use a drive that didn't pass.

One handy feature which I did run on non servers with the software, is that it can monitor the drive and tell me that is suspects failure to be imminent. This is not SMART, though SMART was a first line test, the software went deeper and logged aspects of the drive over time.

Once I started doing this, drive failure went to near nothing. I can't really measure failure in percentage or time, as we would outgrow the capacity of the drive, or the server would be taken out of commission for a faster server before a failure ever happened. Those drives were then given to friends or sold. As a result, we never had an in use failure once we started using this method of testing. 42U worth of server space, with a mix of 1U, 2U, 4U, and a few 6U NAS's, plus switching gear.

Do keep in mind, we were a small local ISP, and could take the time to perform these tests. Someone like BackBlaze has their system created in a way to deal with failure as part of the operation, and it would be a waste of time to perform these tests.
All of this is true, but the implication when we say something like "most of it was paid off" is that the money has actually been returned. In reality, most of it was paid off using new loans that are not under EESA. I could say "I paid off all the credit card debt I accumulated in the last 5 years" after I get two new credit cards and transfer my balances to them, but it would be a bit underhanded to say that.

:)
I was going to say exactly this. Who you take the money from is the most important part of this. Even if the site ends up looking exactly the same, it aligns your interests with the reader's.

There's a pdf on tpb, so there should be a legitimate version somewhere.
Two things:
First, I don't think that huge kinetic weapons would be the ideal choice for this kind of combat. If I'm attacking an asteroid with a huge ass gun on it, I'd first like to have some type of EMP type weapon developed to simply shut down the tracking/aiming/power supply of the asteroid's defenses. Just the threat of an attack like that from orbit would probably be enough, as it would likely shut down life support on the rock as well.

Secondly, assuming that such a weapon isn't developed, depending on what you're mining, it seems likely enough that it won't matter what shape the asteroid is in. For mining solid materials, it would probably be best just to blow these asteroids into manageable pieces and send the whole lot through your enormous space processing plants for extraction and refinement. In this case, you'd need space fleets to protect your "planet crackers" and to protect your processing vessels from other companies, pirates, etc.
> Rhodes was known as "The Empire Builder"

Maybe you misunderstood me. You say that he was a selfless Empire Builder - i.e. he had some zeal to build the English Empire for the good of the queen and England. Yet his true aim was making money (through the British South African Company).

> Who is teaching you this bullshit history?

> Demonizing historical figures instead of studying them in the context of their time is really pathetic.

Trying to whitewash history and historical figures is quite sad. Admittedly I learnt history from a different perspective than you (i.e. from the side of the oppressed and not the opressee).

Yet even in western countries, colonialism is now seen as a bad thing by the majority of people (a few nationalists and apologists notwithstanding).
> They've got cocaine, saliva

I'm not sure drug dealers are really getting a lot of demand for saliva. At least, I hope not. I mean, gross, right.
The study is interesting, but the linked press release is pretty sad, and has been roundly mocked across the internet.

You see, the headline is: "Rare earth metals scarcity: A ‘ticking time-bomb’ for the world, asks PwC?"

This headline would work better if the study was about rare earth metals. It's not. Also, I'm not entirely sure what "flurospar" is, but Google indicates it's some kind of paint. The actual study, as opposed to the press release, includes some discussion of "fluorspar", which is something quite different (although it's still not a metal or a rare earth...).

Again, the study is fine, and doesn't make any of those stupid mistakes, but the press release is shocking.

If I was a teacher that had to have working whiteboard pens all the time, I'd treasure some sort of holster that could hold a good whiteboard pen or two.

It's funny how whiteboard pens are these ugly things that we use all the time. I've never seen a really nice whiteboard pen (do they even exist?). All I've ever seen are those expo white-barreled pens that, while certainly functional, are incredibly spartan.

What would a "worlds-best" whiteboard pen look like? Does it have to be a round, fat plastic thing?
How to Create 3D Rolling Dice In Photoshop
Wow. That is idiotic. At my company, we give all the developers credit cards and tell them to buy what they need. But I try to beat them to it, as I'd rather they focus on coding.

E.g., last week I noticed a couple of developers trying to get a wireless mouse working; they couldn't find charged batteries. Time lost, 5-10m each. So I ordered a dozen sets and two chargers. Cost, maybe $40. (Thanks, Prime!) The opportunity cost of developer time is large (our rule of thumb is $250/hr), so most purchases (including all those you mention) are obvious wins.
Seven Steps to Creating a Data Driven Decision Making Culture.
I'm firmly in the ubiquity camp for this, but with a just-in-time delivery system rather than buying in one giant batch.

Every whiteboard should have a large stock of great pens. If I start to write with a balky pen, I throw it out instantly. (Please, HNers: if you ever see somebody put a bad pen back in the tray, smack them.) When we get down to a merely adequate number of markers in some room, I spend 60 seconds on Amazon and order a bunch more. Prime + One Click + purchase history search makes this a breeze.

WPS Flaw Can Lead to Compromise of Router PINs
How to get an Internship
Since UI, simple
First, the black box doesn't actually do anything safety-critical. It's a pure data recorder, and only comes into play _after_ an accident. You're thinking more of the flight control computers, as well as the air data inertial reference units (ADIRUs).

These components are indeed redundant; from the sounds of the report, one of the ADIRUs malfunctioned (there are three), sending incorrect angle-of-attack data (as well as a lot of other incorrect data). Although the flight computers have monitoring routines for identifying and disregarding erroneous inputs, there was an unforeseen scenario in which a very specific pattern of erroneous AOA data could avoid detection - and this happened here.

It's important to note that the plane was not in autopilot at the time - the autopilot disengaged itself immediately upon detecting an input discrepancy (several seconds prior to the actual pitch down event that caused the injuries) and the captain took manual control. However, due to the fly-by-wire system, the flight controls are normally processed through a rather complex system that (under normal circumstances) helps prevent accidents due to human error (eg, it's impossible to stall an Airbus A330 under normal conditions; the plane will respond to your commands until just before it stalls, at which point it'll force a pitch down or thrust increase to maintain lift).

This invalid AOA data made the flight computers believe the plane was indeed in a dangerously steep climb, in danger of a stall (the stall warnings even sounded multiple times during the flight), and automatic protections called for a pitch down movement (ie, a descent). Due to the precise timing needed for the AOA fault to go unnoticed, some of the flight computers were unaffected - as such, shortly after each of the two pitch down events, flight computer error detection systems triggered failovers - but not until the flight computer currently in charge triggered a descent. The second time this happened, none of the primary computers were eligible for controlling pitch angle (due to each having a pitch-angle-related failure already) and so control passed to a more primitive backup system - incidentally disabling the pitch angle protections that had caused the problems, and allowing the crew to regain control.
Okay, so use a better password creation rule/pattern set like the one in that comic. Just don't throw up your hands and say "oh well, everything will be cracked in 3 days so it's worthless to do anything."
Yes! Socks are definitely best dealt with in batches. I keep two kinds (white athletic and black dress). When one sort is looking raggedy (or the count has fallen below the minimum) I ditch all of that kind and replace them.

This has made me especially happy with dress socks. If you buy them at different times, then they are each a subtly different shade of black, which made me insane whenever I tried to match them.
And in this case, I am talking specifically about security policies for sites that store credit card information, like specialforces.com did. I do not believe that having no password is an acceptable trade-off in this situation.
Facebook now has asymmetric relationships with subscriptions, and the app platform noisiness has improved a great deal in recent years. I just block apps which are particularly noisy.
I suffer the same problem if
1. I do not have proper comments
2. If I less variables. Its always good to use a ton of variables and minimum Constants. When initializing the variable put in comments what it is for.

Whenever I write code I first of all put down all the logic in pseudocode in comments.

Then I write the actual code underneath the logic comments.

Works for me.

How does lung cancer relate to deficiency in the cell cycle?
That's not even near true. Many people are completely oblivious about their weight. Though I highly doubt you will do anything but hurting them by telling them that they're fat.
If your CRC generator gets damaged, then it will produce values that are inconsistent with the CRC checker, which is in another piece of equipment. At which point your component gets kicked out of the system entirely, and all is well. Note also that CRC is an error detection code, and cannot correct detected errors.

I've vowed to never buy seagate after going though 4 RMA's on 4 hard drives on a raid 10 array that failed one after the other within a month time frame. After talking to a service rep about how the new hard drives were failing within A DAY of use I was told 'rma'ed drives are recertified and cannot be bad' and thus was my fault. If you value your data or your time do not buy seagate, at least in my experience.

Personally i try not to lie whenever possible, i prefer brutal truth, i especially appreciate it when given to me, because bullshitting me doesn't help me at all, if you tell me the truth then i can learn from it, if you bullshit me, i wont realise there is a problem.

However, when talking with others, i always try to stick to brutal truth, but word it in the nicest way possible, because lets face it, some people cant take radical honesty. Sometimes i will omit the biggest negative and give smaller negative as constructive criticism and suggest an improvement. While its not full on honesty, i feel its much better than just bullshitting someone.
Wine Gifts  Tips to Ensure a Great Selection

I didn't say that GC was free ... malloc has overhead too.

For interactive programs, I would recommend two things to avoid (or hide) the pauses. Firstly schedule calls which run the GC when it won't be noticed: between frames in an arcade-style game, or just before accepting user input in a turn-based game. Secondly, size the minor heap large enough so that all computation between the scheduled GC runs can happen without invoking a minor sweep (but not too large that the minor heap is wasting memory -- some experimentation and tuning required).

I've written a couple of interactive games in OCaml that used this strategy and avoided visible GC pauses.
Programmers Go Bananas
Median suffers from the very real (ie, seen in a test flight) problem where one side of the plane can give bad data to two ADIRUs, so that's out. Supposedly there's a new system being deployed via a software update (see 7.1.1) that does more detailed monitoring of each channel individually - looking for oscillations, etc. They also got rid of this 1.2-second monitoring period. The report doesn't go into much detail about this though.

Keep in mind, we're not talking about analog noise here. We're talking about one type of data being labelled as another - but only part of the time. Analog filtering techniques might not be helpful, depending on how often it switches.

1. The .com was taken and I really liked Mixmatic as the name.

2. Thanks! I've been really concentrating on my design skills recently. Biggest tip to get good quickly: copy other designs and do it a lot. The design for this site leans heavily on the Instagram homepage. You just need to find another site that captures the feeling you're trying to create with your product and then put your own spin on it. Also looking up how books are laid out especially Renaissaincs era layouts that use the Golden Ratio like the Van der Graaf canon are very helpful. Email me I'd be glad to Skype some time.

I understand Paul has some support on HN, and I even understand why, but there is no way that he can win the election.

This isn't because of some conspiricy, but simply because what he believes isn't supported by enough people. Worse, many (most?) actively oppose at least some of his policies.

Not only will Democrats oppose him, but most Republicans don't believe he represents them (see recent comments from various Republicans about how they wouldn't vote for him)

(Personally, I think SOPA passing would be a minor price to pay compared to Paul becoming President (and I am totally opposed to SOPA - I just think its importance is much less than some of the things Paul would do))
The objection to something big and obnoxious that interrupts your use of the site is only one of the objections to ads. Yes, the pledge drive is annoying. But it only happens for a month or so a year, and it doesn't have all of the other problems associated with ads.

Other objections are that the advertisers would be the ones paying Wikipedia, and thus have the ultimate control; they can threaten to reduce advertising revenue in order to get objectionable material removed, they would incentivize people to put more advertising-friendly content that would draw people to lucrative pages and entice them to click on ads.

Ads are also a security and privacy risk. Advertisers who can inject content into pages can do varios nasty things. And advertisers tend to track what you do; tracking your Wikipedia browsing habits would likely be quite lucrative.

One of the worst things about the internet today is that so much of it is funded by advertising. This gives companies no incentive to act in my best interest; their only incentive as far as I am concerned is to get me to look at their page, so I can look at and click on ads. They are beholden to their advertisers, not their users.
