Comment Speed specialism = iteration! (Score 1) 292

I'll hazard a guess that clock speed excels in one particular case: tight-loop iteration. You can't do that with parallelism (ignoring some fancy pipelining to get part-way there). The fastest way to get the 1 millionth result in a no-shortcut iterative sequence is to get the loop processing at the highest frequency possible.

Comment iPad = consumer device; computer = creative device (Score 1) 622

There's loads of money to be had selling a device has closed content delivery - the iPad is good at that. However, it is not really a device for being creative, which is what a computer excels at, and it's harder for a hardware manufacturer to make money out of that, unless you feed all output into a closed content delivery system...

Comment What is the solution? The cost of Free? (Score 1) 363

I'm not sure what the author wants to make, in real terms. Is it the user base, the third-party integration, the hardware infrastructure? Yes, all of the above, as they're all necessary, but that requires a new build, with different policies. However the viability reduces to the reality of money: money to build it, and money to sustain it. Facebook is now starting to explain the cost of Free.

Comment Better with a subtractive CMYK cell (Score 1) 511

A subtractive cell (stacked CMYK layers, to filter out R,G,B,All respectively) would let more light through than separate R, G, B windows. The article alludes to using a primary subtractive cell (Y) to help one combination, but it would only be 100% brighter for saturated yellows (not whites); CMYK would be about 250% brighter for all colours (not just yellow) with very good blacks.

Ogg Format Accusations Refuted 248

SergeyKurdakov sends in a followup to our discussion a couple of months ago on purported shortcomings to the Ogg format. The inventor of the format, Monty "xiphmont" Montgomery of the Xiph Foundation, now refutes those objections in detail, with the introduction: "Earnest falsehoods left unchallenged risk being accepted as fact." The refutation has another advantage besides authoritativeness: it's far better written than the attack.

Submission + - Building a Web 2.0 site to promote good comments?

MessyBlob writes: When a website invites comments, with any luck there will be more than a dozen responses, which is when the fun starts: you'll need to show the good ones to add value to the site, but at first you won't know which are good. Here's the problem: How can we get the good comments (among many) to bubble to the top: first you need to make them visible, have them rated, and then ensure that any potentially good new comments can be seen in order to be rated as good.

Most mainstream sites fail to do this, so what's the best way of giving all good comments a chance to add value to a site? Is it simply to have, say, 25% of the comments taken randomly from the lesser-rated list, presented among the highly-rated comments? Does time-ordering do the same? Is there a critical ratio of users vs commenters?

Comment Duty of Care on Web 2.0? (Score 1) 484

Yes, this is all about anonymous postings, but surely anyone can make up an identity online? Law has a habit of applying judgements to other cases (in the same country), and encourages prosecutors to take a punt in other countries. In what other cases would this frustrate the everyday running of the web? ISPs failing to moderate comments from their customers? Allowing file sharing?

Fine Print Says Game Store Owns Your Soul Screenshot-sm 262

mr_sifter writes "UK games retailer GameStation revealed that it legally owns the souls of thousands of customers, thanks to a clause it secretly added to the online terms and conditions for its website. The 'Immortal Soul Clause' was added as part of an attempt to highlight how few customers read the terms and conditions of an online sale. GameStation claims that 88 percent of customers did not read the clause, which gives legal ownership of the customer's soul over to the UK-based games retailer. The remaining 12 percent of customers however did notice the clause and clicked the relevant opt-out box, netting themselves a £5 GBP gift voucher in the process."

Comment Quality not quantity (Score 1) 69

This model seems to follow 'genetic programming' principles, but is flawed in many ways: (a) It assumes that most people know everything relevant to the problem under consideration - they often don't.

(b) What the model is looking for is an expert among the crowd. On average, you can find an expert among 1024 people, to predict 10 coin tosses - this is with random data having no relation to specialized wisdom.

(c) Eurovision (mentioned above) is in the rare category of scenarios that can make use of 'crowdsourcing prediction', but only because the simulation correlates to the probable reality: it's effectively a poll, where the opinions of lots of people are used to model the opinions of lots of people.

(d) Can you really assume that if someone gets it right 10 times, the same person will get it right a further 10 times? It needs to be the same specialism.

(e) You'd need to iron out the randomness by running lots of trials that will be of no use to anyone. Can this operate commercially?
