Amazon Pushes For National Internet Sales Tax

Late Adopter Not to mention the slippery slope (392 comments)

If Amazon concedes that states and localities have enforcement powers beyond their borders for taxing purposes, will Amazon also need to be subject to ALL of the sales regulations imposed by their customers' jurisdictions? Will I get a big pop-up saying that a switchknife of the length I've chosen isn't legal in my city? Will they have to check ID for M-rated games?

Neal Gafter On Java Under Oracle

Late Adopter Re:Still no way for overloading operators?? (130 comments)

You're right, strictly speaking, but what I was referring to was commutivity of the algorithm, not necessarily the result. You want to know that whatever decides (a gt b) is also going to decide whether (b gt a).

Neal Gafter On Java Under Oracle

Late Adopter Re:Still no way for overloading operators?? (130 comments)

Yes. At least for me with Cpp, using + for string concatenation leads to more headaches than it's worth. I prefer to use boost::format.

Neal Gafter On Java Under Oracle

Late Adopter Re:Still no way for overloading operators?? (130 comments)

Operators imply commutivity (a+b = b+a). You can't guarantee that if the function is implemented by a or b. It's a bad idea that leads to subtle errors down the road.

Is There a Hearing Aid Price Bubble?

Late Adopter Re:Since no one ever buys them... (698 comments)

Non-profits can and often do take in revenue in excess of their costs (they wouldn't be very stable otherwise!) The difference is what tax law allows them to do with those profits (reinvest in their business vs. distribute to the owners).

Amazon Folds In California Sales Tax Deal

Late Adopter Re:Actually... (639 comments)

The value of goods and services is in the eye of the beholder. Parties engage in trade (and employment) because the perception is that both sides stand to gain.

Amazon Folds In California Sales Tax Deal

Late Adopter Re:BS taxes (639 comments)

It's all a wash as long as total revenue as a percentage of GDP remains the same, right? You're just collecting it from somewhere else (incentivizing/disincentivizing different things).

That said, all the taxes you've listed are probably better for society than sales tax. Disincentivizing consumption and targeting the poor are two things that generally aren't great for an economy.

Is Tablet Success Bound To Their Crackability?

Late Adopter Re:Data Security Anyone? (339 comments)

But what about in a corporate environment, where the OWNER is distinct from the person in physical possession of the device? Can we at least have some basic infrastructure to ensure that when a device is going to be permitted to access sensitive resources/material, it has some verifiability of its state?

Google Is Grooming Chrome As a Game Platform

Late Adopter Re:Does anyone (127 comments)

If you only allow a subset you don't get native speed, you get the speed that your subset of instructions allows.

The inner sandbox uses static analysis to detect security defects in untrusted x86 code. Previously, such analysis has been challenging for arbitrary x86 code due to such practices as self-modifying code and overlapping instruc- tions. In Native Client we disallow such practices through a set of alignment and structural rules that, when observed, insure that the native code module can be disassembled reliably, such that all reachable instructions are identified during disassembly. With reliable disassembly as a tool, our validator can then insure that the executable includes only the subset of legal instructions, disallowing unsafe machine instructions. The inner sandbox further uses x86 segmented memory to constrain both data and instruction memory references. Leveraging existing hardware to implement these range checks greatly simplifies the runtime checks required to con- strain memory references, in turn reducing the performance impact of safety mechanisms.

As long as you weren't trying to write self-modifying code (and note most compilers won't do this), your performance impacts are basically restricted to checking non-local jumps. Not strictly native, but close enough.

not native speed as to sandbox you must create a vm like system.

That's provably untrue. See AppArmor and SE-Linux, both of which operate without creating a virtual machine (only implementing replacement system calls).

Ask Slashdot: Math Curriculum To Understand General Relativity?

Late Adopter Differential Geometry is the key (358 comments)

Differential Geometry will give you the mathematical foundation for expressing non-flat spaces. From there, GR is "just" the Einstein Field Equations and the implications thereof. And compared to, say, quantum mechanics, there's very few solvable exact solutions to make case studies out of (black holes and possible evolutions of the universe, really).

Springer has an OK book on Differential Geometry, and then you want to move on to Gravitation, by Misner, Thorne, and Wheeler.

What's the Carbon Footprint of Bicycling?

Late Adopter Re:Pure LOL (542 comments)

(I am reminded of the time in college when as a grader in a physics class, the students were asked to find how high a pressurized leak on a water tank would shoot into the air. Two student's answers had the water at escape velocity speeds, sending them into orbit the earth.)

I get your point re: reality checking, but as an aside, any velocity straight up without a sustaining acceleration will eventually come back down. Escape velocity is the speed tangential to the surface of the earth (i.e. on the least energetic orbital trajectory) that is in excess of what gravity can keep pulled to the surface (g $lt; v^2/r). And you still have to fight against air resistance trying to decelerate you while you're inside the atmosphere.

RIAA Math: Sell 1 Million Albums, Still Owe $500k

Or at least they've managed to make a large number of people, including you, think so. Surely for their purposes, that's good enough.

Calling BS On Unpaid Internships

Late Adopter Re:moronic proposition (427 comments)

Do you have evidence there's monopoly forces at work? From an outsider's perspective it appears to be a classic supply and demand problem with too many people who want to be interns.

Court on Video Games: Less Cleavage, More Carnage

Late Adopter Re:There is no obscenity exemption (397 comments)

That's the "strict constructionist" point of view. Many people (most?) hold a more moderate point of view that the Constitution shouldn't be interpreted in such strict black and white, and that if the Constitution held every exception to the rule the framer's had in mind, and WOULD have had in mind if they could predict all new situations, it would be as long as some of the bills congress passes, printed on 7000 sheets of paper.

GNOME To Lose Minimize, Maximize Buttons

Late Adopter Re:Why not actually try IT (797 comments)

You might want to change your Downloads folder to /tmp. It enables you to forget about the file once you're done using it (and encourages you to put it somewhere more meaningful than "Downloads" if you want to keep it).

NASA Wants Spacecraft For Mars Return Trip

Late Adopter Re:Big companies will design an expensive approach (193 comments)

It's in their interest to come up with a solution that could feasibly be purchased. Too cheap and not enough profit, but too expensive and Congress doesn't pay for it.

Smart Phone Gets Driver Out of a Speeding Ticket

Late Adopter Re:The smart phone got him off? (254 comments)

I'm not from the united states, and I wasn't talking specifically about them.

But you were responding to a comment that DID specifically refer to the US Constitution, and you called it "the most uninformed comment I've ever seen". You owe the author some evidence for that statement.

Microsoft Vehemently Denies Google's "Bing Sting"

Late Adopter Kobayashi Maru (596 comments)

Right. Google challenged Bing to a no-win scenario and now is getting all upset and accusing Bing's winning strategy as "cheating" because it didn't fall within their box of how they thought search engines were supposed to operate.
