A quick pass of bcwipe/shred/etc. just to make them less sensitive during transport, and physical destruction of drives. I pretty much just store the drives until I get enough of them and then angle grinder fun, or, if I have someone paying for it, a commercial drive destruction service (and if they let me, I throw personal drives in at the same time, since it's usually no marginal additional cost).

I haven't owned SSDs long enough to need to destroy any, but some physical destruction is the only way.

I do use full disk encryption on drives and then repurpose machines by changing the full disk encryption keys, but those machines haven't left my control -- it's just for changing e.g. a photo drive to a movie drive.

I'd be a bit conflicted if I were buying FusionIO or high end SSDs, but I generally buy 1) fast/big consumer SSDs and 2) big spinning drives, and keep both in service until they're essentially valueless.

IMO, degaussing is probably a good solution in a high volume environment as an early step, but it's not as good as physical destruction, and it wrecks the drive, so you really need physical destruction.

I dream of having an office with wet lab, machine shop, private SCIF/VTRs and a destruction facility with soundproofing.
That's ridiculous. There are tons of successful developments using public money besides SpaceX.
I agree with a lot of what you said. However, this:

"Competitors will not have the ability to compete on charging when they release cars because Tesla will already have an established network."

is dramatically wrong. They will absolutely compete on charging, stubbornly so, and probably leveraging politics in the process. The major energy companies will also get into the charging business (much like the oil companies did with gasoline stations), and they too will fight with Tesla on standards, and attempt to set their own. The one guarantee is that the energy industry, filled full of extremely powerful companies used to dominating and getting their way, will not simply go along with Musk because he got there first (ditto for Ford and GM). That's not to say Tesla's standard will or won't prevail (or whether several will win out), but rather that there will be a long fight over it, and the competition will be belligerent.
I started a blog today to keep track of my upcoming honours project. My plan is to post things for non-technical people (aka all of my friends) to try and give them some more insight into what a computer science degree is all about.

I'm hosting my blog using github pages, and using octopress, which makes it more fun to work on imo.
Dadgum has a great review of a J programming book here:

I think that is the point. I would tweak the definition a little and say "Legacy is anything that's not fashionable anymore, but working and still being used just because it's working."
HF trading provides liquidity and there is some debatable value to that purpose, but using the speed of light to profit from traders who didn't pay the toll to be closer to the marked pretty clearly doesn't benefit anyone but those in on the scam.

What's right with it? It's an awful language:

Not being able to import/include library code is bat-shit insane. You can't reliably check the type of things like arrays.

The 'this' value is 'wrong' in callbacks (by wrong, I mean, not what programmers actually need in that instance).

Javascript dates values are 1-based except for months which are zero based - be consistent!

Math.parseInt will produce correct results for 05, 06, 07, wrong results for 08, 09 - don't ASSUME a radix! (unless that radix is base 10).

It goes on regardless in the face of a large number of errors meaning that the location of an error can be much harder to find than is necessary - I believe that fail fast is infinitely superior to 'just muddle through and do something random with that invalid state'

You can't rely on getting decent stack traces out of it on error which makes debugging harder than it should be.

It's easy to accidently add globals.

I'd add lack of types: obviously that's a preference but when 30% of your tests just end up checking what a compiler could have done for you for free, then I say that;s a fault with the language.

That said, I really like array and object literals. It's not all bad. Just... about 86%
The issue with child support is that the state child support agencies often rely on bureau of labor figures to determine what someone with a particular job "should" be making, and don't consider variance in wages or cost of living when levying child support rates. So while the payments might be reasonable according to some bureaucrats rule book, they aren't reasonable in the real world (a common issue is men with large child support obligations wanting to start another family).

There have been numerous cases of actors whose child support obligations were set at the peak of their career and yet the CSA still expects them to be making the same money.
Hi.

Thanks for the advise and you're right, but this isn't my usual nightly routine. I took her out this weekend, like I do most weekends and I'm taking her away to Germany this summer - she wanted to go ever since I've known her. I'm not the perfect boyfriend, but I really do love my girlfriend and I do everything I can for her. Mine and her happiness comes first, period. The only reason I'm up tonight is because I wish I could give her more.
I agree that things often seem obvious in retrospect, even if they were not obvious before. But that's ok. The point of patents is not to protect things that are obvious in hindsight. The point is to protect things that are not obvious even after you see them. Things that make you want to say: ok, it's right in front of my eyes, but what is this magic?

That's something that would look great in a marble facade.
> And Oculus- so they have little revenue now? They have decent revenue at all for a product that has only been released to developers. You even admit that VR can completely change the world, but don't do the homework to understand they're probably less than 2 years from a product release with massive community and business support? What, did your deadline come up and you just had to submit?

Occulus is a big question mark, honestly. Nobody knows how much it will be worth down the road. Even if the hardware itself is cool, there are several issues facing that market:

- you need additional hardware to use it, and the additional hardware is at least going to cost 500-600 USD for a good experience with the Rift. Peripherals don't have an history of selling very well.

- Currently we don't know if there are going to be killer titles to drive the adoption, and Facebook has zero experience to make games as first party. So they have to rely 100% on third parties which may be an additional risk.

- Occulus is a hardware product. Usually margins on hardware tend to be thin (i.e. thinner than on software), especially as competition is unleashed.

- VR to completely change the world. Meh, we've heard this in the past 20 years every single time something new came out from Silicon Valley, yet the world is very much the same - there were very few massive disruptions. I could think of a dozen reasons why most people wouldn't want to use VR on a regular basis.

- The game industry is not in a very healthy state right now, and if supposedly the Rift is going to be mainly for gaming, I'm not sure what this says about its future.

Of course, the Occulus Rift could ending up being very big, but it's actually a risky investment at this stage since there's not much proof of what size you can expect in terms of market at all.
While we are on the subject, I would love to see "car chassis + engine + trans" as a service.
What's amazing is that Tesla has been providing NRE R&D for OTHER automotive companies for years already. Last year, $15 million of their revenue was from development services but as early as 2011, $55 million of revenue (>25%) was from basically doing powertrain design for companies like Toyota and Mercedes.

Tesla will definitely make a killing on batteries. I actually think the supercharger network is going to REMAIN proprietary as a competitive advantage for Tesla vs. other electric car companies. As someone who's done research in this in the past, there are already well-established standards adopted by the IEEE and companies like GE for charging. This is obviously to encourage the adoption of the technology.

However, since most electric charging networks are run by private companies or utilities, we may have the "roaming charge" issue that telecom had once upon a time. In other words, if you lived in Texas and got your electric charge from your local utility as part of your monthly bill, you may have to pay "roaming charge fees" for charging in California.

But if you're on the Tesla network, the "fuel" is part of your purchase price. This is Apple-level walled garden tactics and it demonstrates the foresight of Elon Musk and his team. What an incredible entrepreneur.
Lots of comments against this posting, but I don't find it that bad, I'm sure there are worse. If you think about the product they are building, I think this ad is suitable. They don't want to hire people who are afraid of sex. They want to hire sexually liberated developers. I don't find anything in the ad which is particularly offensive to women, unless you're just considering the photo (which I think changes if they think you are a guy or a girl).

The sexual innuendo fits. Clearly if you're offended by this, you're not the right person for this company, but I suggest they've done a good job of balancing the type of people they want to hire, without sounding like they only want horny boys who are trying to get the inside scoop on a hook-up app.
Fair enough. I just compose my mixins directly and bridge the gap through delegation. I wish these rants included the obvious solutions, I'm really tired of the argument of OOP sucks because...Java. Or OOP sucks because...single inheritance. There are plenty of things we can do to make our languages not suck, and this is not a fundamental limitation of OOP.

Upvotes for an intelligent debate.
I agree with you that it looks like a legitimate PR strategy, but in this case I don't buy that.

Look at the context of how this info was delivered. This wasn't some response to a journalist or a press release, it was a reply to a reddit thread that Palmer has frequently chatted on. At around about the same time that evening he also went in to if Star Wars lore about the Expanded Universe was being killed by Disney or not, or if Yuuzhan Vong was a force power in the balance prophecy. It seems unlikely this was a centrally masterminded PR strategy but just someone saying what was on their mind at the time. He may have good PR instincts, although even thinking that seems cynical to me, and it seems random enough to be an honest comment.
Thanks for the link.

As for CBS. I don't want your g@$
We've needed one for ages! Lithium ion is the best we can do so far, and it has two GAPING flaws:

* tons of energy is lost as heat
* volatility of the chemical storage mechanism occasionally causes that heat to get released as an explosion

I'd love to see Musk's solution end up in a massive increase in battery performance.
I see no harm in doing so. I have a ton of books in digital formats, just never thought about buying a physical copy before. The only reason I did so this time is because I have some travelling upcoming, so it's ideal to read on the plane.
Yes, but... there's a difference in what happens when you try to do away with them. Society without physical property rights requires everyone to abide by fair evaluation of what they need and what others need; otherwise, anti-communal individuals take things in order to enrich themselves. The people they take from are either non-violent and end up not being able to feed or clothe themselves—limited only by the conscience of the person taking unfairly—or else there's extra-legal armed conflict. Even if everyone agrees to the principle of equitable sharing, a communal ideal, there are still mismatches in different people's evaluation functions of need and ability.

I think the drug market can be viewed as a microcosm of that. There are no state-enforced property rights in drugs, at least none that anyone outside the drug trade takes seriously. It doesn't turn out very well for anyone involved in the market. Even those who get rich from it are at greatly increased risk of turning up dead.

Abolishing IP would affect income streams, but so does outsourcing, automation , and change in particular job markets or industries... the onward march of progress. I don't see that as a reason why it shouldn't be done.
Public money doesn't save incompetent people: read about Eike Batista from Brazil who had a net worth of 30 billion dollars in 2012 and now has a negative net worth (reported by Bloomberg in January 2014).
I always thought that the digital stock market should take a page from the cryptocurrencies and add a digital proof-of-work that will cap the speed of a transition. A "temporal tax" would keep the system from wild swings and reactions, similar to what we saw a few months back.
i didn't mean to say that MongoDB was the only database with that property. Yes, CouchDB does as well.
I'm still going to bet on the guy who has put something in space.
Sort of ... but there are pretty serious limitations.

1. You are locked into Rackspace as your provider. MongoHQ provides multiple cloud providers.

2. They force you to shard. This increases operational and application complexity ... and may not offer any real advantages for the amount of data that you have.

Here's the better idea. Get a 9 to 5 six figure job. It will be boring, I know. Life sucks like that sometimes. Most of us have one.

Next, live like a pauper, saving 60-70+% of that income. Spend your free time doing exactly 3 things 1. working on a side project 2. spending time with your girlfriend. 3. exercise (never count this out, no matter what your life circumstances otherwise)

Then just wait 5 more years. You will either have something going from your side project or you will have enough money saved to legitimately work full time on something without worrying about bills

As far as the idea, go for something as boring as possible. Preferably something that someone else is already paying money for but that the incumbent product is shitty or lacking in some major way. Fix it or make it signficantly cheaper. Business is just a wrapper around value.

Create value, get paid. That's how capitalism works.
Thanks for the comment! I'll have a look at the link.
Yes, and my "like" in the "like SpaceX" was meant to acknowledge that fact. Thus, not ridiculous at all.
Could someone please explain to me how the IPCC can be calling for urgent action when their models are looking increasingly busted?

http://judithcurry.com/2014/03/04/causes-and-implications-of...

I can see three main possibilities:

- their models aren't busted (Judith Curry is wrong, as are those whom she cites)

- their models are busted, and that increases the risk (i.e. risk increases as a result of forecasting being essentially impossible)

- their models are busted, and they're doubling down on a bad bet for political reasons
To be fair, Anonymous' trouble with the law has nothing to do with copyright, and people are not generally assaulted by SWAT teams for having folders containing copyright material shared with them. Even in the Megaupload case, the indictment included a long history of incriminating emails, not a single setup by an informant or slip-up.

But yes, if you want to run a file sharing site whose main purpose is uploading copyrighted material, you had better avoid leaving a paper trail containing anything damaging.
Wu-Tang Clan redefines music as art, will release only one copy of new album
It is hard to argue, however, that Javascript (the thing Cofeescript purports to improve) doesn't "allow you to write bad code easily" or "makes it hard to write bad code". I have avoided Coffeescript and probably will continue to do so, but it seems to at least try to make it a bit harder to write bad code, albeit not getting all the way there apparently.

> In practice I find most upper-middle-class-and-wealthier Americans just don't walk anywhere, especially not after dark.

We're actually in the midst of an urban renaissance. Being able to walk everywhere is one of the perks of being wealthy in America. Especially among people under 40. This is why there's so much angst over "gentrification": walkable neighborhoods are being rapidly bought up by the relatively wealthy. And because America is saddled with so much terrible sprawl, there are only so many walkable neighborhoods to go around -- hence skyrocketing real estate prices.

Along with gentrification comes lower crime. In fact there's no longer any overall correlation between crime and density in America. Crime in the cities (taken in aggregate) has fallen to the point where there's no longer any statistical difference between urban and suburan/rural crime rates.

Lots of people don't believe that, but that's just because they hold out-of-date beliefs, which they maintain through confirmation bias.
Thanks for asking.

I work as a web developer. I have been building eCommerce sites since I was 15~, I'm 23 now! I can do frond-end and back-end development, although I think I'm better at back-end development. I have good experience with HTML/CSS/Javascript, PHP/MySql, Java & Node.js. I also have some experience in building AI systems using ANNs, GAs, etc.
In C#, you define an interface, and in the same namespace as the interface, you define a set of extension methods to the interface. Any class that implements the interface gets the extension methods. The interface can even be empty.

namespace Yarp{
public interface IMixinFoo{
}
public static class IMixinFooExt{
public static void DoBar(this IMixinFoo _this){
Console.WriteLine("poo");
}
}
}

namespace Grog{
using Yarp;
class Baz : IMixinFoo{

public static void Main(string[] args){
Grog g = new Grog();
g.DoBar();

g = null;
g.DoBar(); // still works, if DoBar guards against a null-ref exception
}
}
}

Correction: both type 1 and type 2 diabetes have genetic risk factors. In fact, genetic factors are stronger with Type 1. I would expect to see subtype categories filter out into the mainstream in the next generation or so, as the explosion of diabetes in the developed world carries discussions of it out into the wider population. The current primary differentiator between Type 1 and 2 is Type 1 is an autoimmune disorder, while Type 2 is an insulin resistance disorder.
In the immortal words of Keanu Charles Reeves, "Whoa". So much admiration for this guy. For once, it's actually nice to see one of my heroes getting mainstream media coverage like this. The guy has broken through to the mainstream by being himself and staying true to his engineering roots. You look at a guy like Jobs and it was always such a hokey, patronizing, and calculated exercise with his Houdini-esque product launches. Elon's humility and grit should be an inspiration to all.
What's the point? The first person to get the transaction still makes money, so there is still an incentive to get the information first. Everything will just be on an arbitrary delay. And what's wrong with swings and reactions? That's supposed to happen as new information comes in which changes things. If the people reacting are wrong, they lose money and the people who see it make money.
"it's clearly none of Dropbox's business"

Actually, it's a core piece of Dropbox's business. One of the ways they save on storage is by comparing hashes of files (or even parts of files - how many bits of any two JPG or DOC files are identical?) being stored and, if identical, only store one copy of the file. That and they explain in plain english that they're allowed to do that.
That they explicitly say they do as much in their TOS puts the onus on the user to not store anything they're concerned about the privacy of on Dropbox's servers.
The combination of some very intelligent people with often very poor social skills will give a greater chance of things like this happening...

That said, they could be a little more honest about recognising why people don't like this deal...

He's established both things. First, that class hierarchies are bad when they break encapsulation (he calls this the engineering problem with them).

But he also argues that they don't accommodate change well by their nature (he refers to this as the semantic problem):

>> Furthermore, the idea of building software on top of a tree-shaped ontology would be broken even if our knowledge fit neatly into a tree. Ontologies are not used to build the real world, they are used to describe it from observation. As we learn more, we are constantly updating our ontology, sometimes moving everything around.

>> In software, this is incredibly destructive: Moving everything around breaks everything. In the real world, the humble Platypus does not care if we rearrange the ontology, because we didn’t use the ontology to build Australia, just to describe what we found there.
I live near 19th Street BART, and honestly I feel safer after dark in downtown Oakland than I do any time after 8 PM around the Powell Street station. I usually go for a run after sunset around Lake Merritt and there have only been a handful of occasions where I felt uncomfortable.

The other night I saw a young woman walking by the lake at 10 PM while talking on her iPhone -- and that seems normal for me as a newcomer, but my wife grew up in Oakland and tells stories from the 90's when it wasn't smart to park your car by Lake Merritt in the middle of the day on a weekend, let alone go for a walk by yourself at night with your phone out.

What I don't understand is given the skyrocketing real estate prices in San Francisco, versus the much cheaper and undeveloped density that the BART corridor could support in Oakland, why more high-density residential isn't springing up on this side of the bay.
