The proof is a sequence of extremely easy logical inference rules like if A=>B and A then B. You check the correctness of the proof by verifying that these rules are applied correctly. Obviously though, there is no way to prove that your mathematical model corresponds to reality. That is because mathematics is not concerned with reality.
Congrats, Holland. Way to go.

Hopefully this will spur europe to move forward, as a union, to enshrine net neutrality into law, and hopefully prod the US into action.
Weren't those complaints about nix's complexity though? The complaints about things like the nix filesystem were specific enough that it's a stretch to point toward Windows.

I agree with the sentiment, but "Google execs knowingly assisting illegal operations peddling illicit drugs from manufactures unknown?"

I think it's more like Google knowingly helping people bypass the pharmaceutical equivalent of DVD Region-coding.

The drugs people were buying were the same stuff you guys get down there in the states, they were just available for cheaper because Canadians pay less for drugs. It's also my understanding that Canada has stricter regulations on drug safety than the US, so your portrayal seems a bit FUD-y.

From wikipedia (http://en.wikipedia.org/wiki/Pharmacy#Internet_pharmacy)

"Canada is home to dozens of licensed internet pharmacies, many of which sell their lower-cost prescription drugs to U.S. consumers, who pay one of the world's highest drug prices.[11] In recent years, many consumers in the US and in other countries with high drug costs, have turned to licensed internet pharmacies in India, Israel and the UK, which often have even lower prices than in Canada.
In the United States, there has been a push to legalize importation of medications from Canada and other countries, in order to reduce consumer costs. While in most cases importation of prescription medications violates Food and Drug Administration (FDA) regulations and federal laws, enforcement is generally targeted at international drug suppliers, rather than consumers. There is no known case of any U.S. citizens buying Canadian drugs for personal use with a prescription, who has ever been charged by authorities."

The Prius was criticized for having only a single higher end model early on.

The variations here makes sense. The main variables seem to be of fairly modular components: battery, motor controller/inverter, wheels+tires, suspension and trim. And of course paint.

This fits exactly with the Apple strategy of pricing variation in an area that is valuable to the consumer (e.g. storage/RAM/CPU-clock), but fairly modular and easy to create and support.
I don't understand your reasoning..?
It depends on the scope of the proof. It's sloppy to say "this is proved to be correct". They should say "this is proved to be terminate with output X in a finite time, for input values in the range -Y:Y".

Everything can be proved to be "correct", for some definition of "correct" (i.e. "output undefined, program may not terminate").
A joke in bad taste, dude.

The early reviews of Model S handling and ride were very favorable, and it makes sense that they would be due to its very even weight and low center of gravity. I don't know if it's in the same class, though.

Very old news. Still, a very relevant object lesson in how this has come about. Not because the Netherlands is so progressive in tech legislation, but because of a few greedy mobile telecom operators were stupid and arrogant enough to offer politicians an easy scoring opportunity.

This also explains why despite this apparently progressive stand on net neutrality, there has been virtually no upheaval surrounding the court order to block the Pirate Bay, or the government support for ACTA.

Net neutrality in the Netherlands was a political "accident", not a sign of a certain political climate. Neither Dutch politicians nor the Dutch media really give a shit about digital civil rights.

The "2010 and later" section is empty. I guess it's possible that they stopped building new products which use GPL code in 2009, but somehow it seems unlikely that they stopped updating or patching old ones at the same time. If it takes them two or more years to ship the source, after they're already shipping the binaries, are they in compliance?

I tried Blekko for a bit this past fall and was not terribly impressed. I, frankly, don't understand what the /slash notation is doing. is it a filter? Is it a specific type of search?

However, I have been using DuckDuckGo almost exclusively for the past 2 months and I'm not sure that I'll be going back anytime soon. DDG is touted as being for the privacy conscious, but I can't say that was my primary motivation in switching. I have been increasingly unhappy with Google's 'bubbling' and my searches there increasingly felt like I was running in circles through crappy mailing list archives and spam sites and all their new 'features.'

DDG brought back memories of what drew me to Google in the first place, over a decade ago. It is clean, straightforward, and relevant. Yeah, I know it's running on Yahoo Search APIs which are running on Bing, but it's still a drastically different search experience.

Finally, doing a bit of research into DDGs extras and the !bang notation pages kind of sealed the deal for me. Want to know your IP address? just search "ip" Want lorem ipsum text, just search for that. Want to search the python documentation? Just use !python. Want to re-run your last search in Google? Just add !g Those features alone are enough to make it a true power user's search engine.

How is that meaningless? It's what determines a large portion of the price of the car and it's range. You don't think it's helpful to know that the Leaf has a 24 kwh battery and the low end Tesla has 40? I'd say the range "estimates" are the useless number. The range is 90% determined by the battery capacity. The range estimates are whatever number marketing pulls out of its ass. This is nothing like megapixels and megahertz.
Funny you asked. I signed up couple of days ago, deciding that slash tags should be the best way to get rid of all the crap in google's search results. I was a little confused though. Does Blekko expect me to choose which slash tag I want to use for my query? If that is the case, I think it will be hard for them to go mainstream. I can do it, no problem. But an average user will not be able to. I was expecting some sort of an intelligent algorithm which would decide which slash tags to use with my query. I think it all should be seamless to the user. They should curate the slash tags themselves and apply them to the search queries when relevant.

They've been around for a while. So I think it is fair to expect more powerful features from them. Color me worried. It would be a shame if they don't get more momentum. I think their idea of slash tags is a killer one. I just think they have not implemented enough or going to the wrong direction.

To sum up:
1) slash tags are just brilliant.
2) slash tags should be seamless to the user and be applied by Blekko automatically to each search query.
3) They should build their own slash tags, not relying on crows sourced ones. They should go crazy about this. Doesn't seem like they are.
4) More power to them. I love them
Apple: What Did You Do to AirPort Utility?
As long as your hardware can handle it, it's more than worth it. A few points:

1. I have a rule - never install server software on my base machine. Servers and server frameworks (like Rails, Jetty, PostgreSQL, etc.) are only allowed on server OS's (Ubuntu Server) running in a virtual machine. That keeps a lot of cruft and extraneous processes out of my base install, while also quarantining them into easily clonable virtual machines, should I want to recreate the vm for something. I only break that rule with one thing - I run Nginx on my host OS, and just point it at different vm appservers.

2. It helps separate your work for multiple clients. So you could setup three vm's for client 1 and three for client 2 like so - client1-webserver.vdi, client1-appserver.vdi, client1-dbserver.vdi; client2-webserver.vdi, client2-appserver.vdi, client2-dbserver.vdi.

3. It lets you more accurately simulate the production environment of an n-tier application locally, so your dev environment will be closer to prod than if you ran all these server apps directly on your base machine.

Only caveat is you need the hardware to support this. Enough disk space for multiple ~10GB vm's, enough RAM to hold them in memory, and a CPU with VT-x (and VT-d if possible) and lots of cores. I particularly like Intel's Sandy Bridge chips for this, since every core is hyperthreaded, making it appear to the OS to have twice as many cores as it actually does. Each vm can be assigned one more more core.

That's about it. Try it with Virtual Box and see what you think.

Why do people want a bigger battery? Why is it something to headline? Why would someone pay $20,000 for more kWh?

It's not because people want to masturbate to a bigger number for $20,000. Because they care about RANGE. That's it. That's what actually matters. The closer you get to that number the more relevant it is to the consumer. You can estimate it, massage it, even lie about it. But at the end of the day, that's what the consumer is actually buying.
Ouch. Well, it looks like you get to be an early adopter of IZ!
I must say I am really impressed by the speed and performance of SublimeText 2. If they can get the vintage mode (vim mode) right, I might really consider switching. At the moment it's nowhere near perfect.
The programs that can be proven are severely limited in power. For one, the tools to prove correctness of programs can't deal with data other than integers[1].

The way this usually works is that the proof is written and the code is then generated from the proof. That code is then incorporated in something larger, which has not been proven correct. Such is the case with algorithms. You can mathematically prove an algorithm correct. You can even write a proof and generate a program from it. Then you still have to use that algorithm and all the code using it can't be proven correct with current methods. That is why you will still have to test your program.

There are even entire programming languages designed for
the sole purpose of making formal, mathematical
verification of programs easier.

Yes, and their practical usefulness is still severely limited.

[1] Of course, in theory this means they can deal with any data; in practice it means they can't.
Remind me to never compete with you.
Yes. It is meaningless to know the Leaf has a 24 kWh battery and the Tesla has 40 kWh. Completely and utterly useless.

Range is determined by engine, weight, aerodynamics, and, yes, battery. The Leaf could, hypothetically, weigh half as much as the Tesla Roadster S, have a better coefficient of friction, a smaller engine, and get BETTER range with a smaller battery.

It's like telling people how big the gas tank is on a car. There's a hell of a lot more you need to know to figure out the range. To give an extreme example, just because my passenger van has a 30 gallon tank and my civic has a 11 gallon tank doesn't mean the van is going to win an endurance race.

Edit: Another concrete example, the Volkswagen 1L. It has a 1.7 gallon gas tank and gets a 400 mile range. [1] Your average Toyota might have a 50 mile range on the same amount of gas.

My advice is to be honest. Tell the new offer "I never heard back from you guys, so I accepted another offer. I wouldn't feel right leaving them in the lurch, so it'd a have to be a significantly more interesting offer and I'd need some time to sort things out here without disrupting plans they've made based on hiring me.". There's probably no need to tell your current boss anything until _after_ (if) the "significantly more interesting offer" eventuates.
Great thing to do but it doesn't seem to teach much of the basics. I'm not a developer but learning the core concepts of Programming at the moment and I can see someone doing the same thing for HTML may not understand anything about tags if they have no experience at all.
Yeah, but what if I'm buying a Tesla Model S... so all else is held equal? I don't understand how you don't see this as useful information when comparing options within a single line of vehicles.
You have to remember, developers close to a platform always live 6-12 months in the future, at least. (Talk to Brendan Eich about JavaScript, he's like 5 years in the future.)

What "finished" means in this context is that we've established which problems we're going to solve, and the solutions to those are well-understood. There aren't new problems that node-core is setting out to address by making changes to the binary itself.

The new hard things to tackle are above the core layer - CI, userland module documentation and discoverability, binary deployments, etc. There's quite a bit of polish and refinement to be done at the lower level, but the paths are clear at this point, as far as that goes.
This is all bad karma for Google. At some point they'll do this to the wrong person and, when that happens, I do hope that they pay the price in mega-bucks. This is no way to treat decent and honest partners. It is, without a doubt, being evil.

I experienced another surreal variant of this a few years ago. We had some 200 domains in GoDaddy's "Cash Parking" program. They were there for probably a year when someone made the observation that the ads on these parked domains were all served by Google. Google, at the time, offered something called "AdSense for Domains". We decided to switch all domains to Google's domain parking program and cut out GoDaddy. No delusions here, neither service was going to make any money but it seemed a better idea to let parked domains host relevant ads without unpaid GoDaddy ads.

Now, to be clear, when you make this switch Google controls the content on the domains and, of course, they own search.

All went well. The domains started to show ads as expected. Then, out of nowhere, Goggle kills our account. No recourse. No intelligent conversations. A totalitarian and decidedly-evil "we are done" of sorts.

Not one person from the office clicked on any ads. Far too busy making real money to do crap like that.

Several of the domains we parked belonged to clients for whom legitimate sites were being created. Google's actions were brutally violent. There's almost no other way to describe it.

Being that they are a de-facto monopoly I would imagine that a time might come when they migh lock horns with exactly the wrong person or entity and end-up on the receiving end of congressional action or some such thing. I really do hope this happens and that they suffer serious damage because of it.

It is so ironic and frustrating to come across site after site with crap content full of Google ads and, on the other hand, to see honest site operators being punished by having an important source of revenue cut-off like that.

I love many of Google's products but AdSense and AdWords' management, policies and their brutal handling of honest users who add nothing but value is nothing less than evil.

I don't like the fact that people either love Microsoft or don't. The same applies to Google and Apple. As developers, we should always objectively question all big companies and give them credit when they deserve it.
I, for instance, hate Microsoft for not living up to its potentials. I don't hate because it sells its software, but because, it creates a vendor-lock set of software, preventing integration of third party tools and making their clients completely dependent on them.

Well it makes sense, doesn't it? The costs for a mobile network provider are largely fixed and not really tied to consumption (it's maintenance and predictable/steady network upgrades).

Calls and SMS don't really cost the network anything (aside from inter-network fees). They're priced in such a way so that with the assumed amount of customers, they'll recoup their fixed costs. If people stop making calls and sending SMS, they lose that predicted income and have to recoup it from other sources (either the fixed monthly fees, data fees, or tacking on bullshit service charges).
The term "illicit drugs" is a little disingenuous. Google wasn't posting ads for heroine. They were posting ads for pharmacies that sold Claritin a few dollars cheaper than US sellers.

Slashtags are a way to build specific search domains. The easiest way to understand one is to build one for yourself.

Example: I built myself a /objc slashtag that includes Apple's docs, Stackoverflow, Cocoadev.com, Mike Ash's blog, and a few other sources.

Now, when I go to blekko and search, say, "calendars /objc", I get only info about calendars in objective-c from those sources, and no noise.

Edit: I find this rather more useful than DDGs ! Syntax in that it's user-extensible, and lets me aggregate many site searches into one slashtag, rather than just punting me to a specific site's engine.

flock() is not trivial to do in a portable way. For a unix-only flock(), check out the fs-ext addon. Same for mktemp.

I wouldn't be opposed to either being in core if it could be done in a clean way, but this is just adding another knob that can be done with an addon easily enough. If you care more about having flock() than about writing portable programs, then that's what the fs-ext addon is for.

What if you make a mistake in checking the proof? Sure, that may sound silly, but mistakes are the point at issue here.

The usual rejoinder is that you can use an automated proof checker/assistant like COQ. Now you're relying on a program. Is the program correct? Well, we checked it with itself...

I admit this is far better than not having a proof at all. As I said, it's a tool, and has pragmatic merit. My objection is it's not absolute proof - which is what "proof" sounds like to me. In reality, a proof is an argument for the truth of a claim, with a level of convincingness.

BTW: Admittedly, reducing a proof to simple rules makes it harder to get wrong, though this is rarely done by mathematicians. Also, it's a curious fact that some mathematicians have made mistakes in their proofs, but turned out to be right anyway, presumably because they could see that it was true, and the notation was secondary.
