Hence a single score is completely unsuitable to address the "quality" of the algorithm, because there is no single benchmark scenario.

So you're saying that no benchmark is meaningful because no single benchmark can be relied upon to be the final word under all circumstances? By that logic, measuring speed is not meaningful, because it's not the final word in all circumstances. Measuring the compression ratio is meaningless because it's not the final word in all circumstances. The footprint of the code is meaningless because it's not the final word in all circumstances.

Isn't it possible that a benchmark could be useful for some purposes other than being the final word in all circumstances?

Depending on what you're talking about, providing a huge table of every possible test doesn't make for easy comparisons. In the case of graphics cards, I suppose you could provide a list of every single game, including framerates on every single setting on every single game. It would be hard to gather all that data, and the result would be information overload, and it still wouldn't allow you to make a good comparison between cards. Even assuming you ad such a table, it would probably be more helpful to add or average the results somehow, providing a cumulative score. Of course, then you might want to weight the scores, possibly based on how popular the game is, or how representative it is of the actual capabilities of the card. But if that's the result that's actually helpful, why not design a single benchmark that's representative of what games do, rather than having to test so many games?

there's not a meaningful way to pick the "best" in that group that everyone will agree on

Metrics often don't provide a definitive answer about what the best thing is, with universal agreement. If I tell you Apple scores highest in customer satisfaction for smartphones last year, does that mean everyone will agree that the iPhone is the best phone? If a bunch of people are working at a helpdesk, and one closes the most tickets per hour, does that necessarily mean that he's the best helpdesk tech?

It's true that a lot of people misuse metrics, thinking that they always provide an easy answer, without understanding what they actually mean. That doesn't mean that metrics are useless.

If you're comparing a bunch of cars that get 32-35 mpg and go 130-140 mph, there's not a meaningful way to pick the "best" in that group that everyone will agree on

Yeah, but that's a really dumb metric since most people don't actually care what the top speed of a car is. Or to be more truthful, only morons care about top speed unless it's below 80mph, since you basically shouldn't be driving your car that fast. So really, in a metric like this, the "top speed" isn't a metric of "faster is better". It's a metric of "fast enough is good enough".

But if you were in the habit of doing car reviews, it might make sense to take a bunch of assessments, qualitative and quantitative, like acceleration and handling, MPG, physical attractiveness, additional features, and price (lower is better), and then weigh and average each score. That would enable you to come up with a final score which, while subjective, makes some attempt to enable an overall ranking of the cars. In fact, this is the sort of thing that reviewers sometimes do.

Since the "correct" weighting is a matter of opinion and everybody's use-case is different, a single-dimension metric isn't very useful...[snip] User A is trying to stream stuff that has to have latency less than 15 seconds, so for him the first algorithm is the best.

And these are very good arguments why such a metric should not be taken as an end-all be-all. Isn't that generally the case with metrics and benchmarks?

For example, you might use a benchmark to gauge the relative performance between two video cards. I test Card A and it gets 700. I test Card B and it gets a 680. However, in running a specific game that I like, Card B gets slightly faster framerates. Meanwhile, some other guy wants to use the video cards to mine Bitcoin, and maybe these specific benchmarks test entirely the wrong thing, and Card C, which scores 300 on the benchmark, is the best choice. Is the benchmark therefore useless?

No, not necessarily. if the benchmark is supposed to test general game performance, and generally faster benchmark tests correlate with faster game performance, then it helps shoppers figure out what to buy. If you want to shop based on a specific game or a specific use, then you use a different benchmark.

Regulation doesn't stop scams, it merely makes them more creative. Let's regulate 'till only lawyers can own a business? Scams could be not prevented but undone, by total transparency and traceability, which is easier to implement than you think ("the books have no trace of transactions involving you and this thing? then you don't own it").

But, unfortunately, transparency would expose powerful people and their tricks, so the powerful people allow STASI-like spying and your children groped at the airport, so you rebel and seek comfort in privacy. Checkmate, you lose.

I am against BTC regulation because every time you earn something real or money, from bitcoin or whatever, you should put it in the tax form else you're being dishonest. BTC, like virtual game goodies, fall in this category IMHO.

Can you explain in more detail?

I'm not an expert here, but I think the idea is to come up with a single quantifying number that represents the idea that very fast compression has limited utility if it doesn't save much space, and very high compression has limited utility if it takes an extremely long time.

Like, if you're trying to compress a given file, and one algorithm compressed the file by 0.00001% in 14 seconds, another compressed the file 15% in 20 seconds, and the third compressed it 15.1% in 29 hours, then the middle algorithm is probably going to be the most useful one. So why can't you create some kind of rating system to give you at least a vague quantifiable score of that concept? I understand that it might not be perfect-- different algorithms might score differently on different sized files, different types of files, etc. But then again, computer benchmarks generally don't give you a perfect assessment of performance. It just provides a method for estimating performance.

But maybe you have something in mind that I'm not seeing.

And don't misunderstand me. I'm not trying to claim that bitcoins aren't worth anything. But Garbage Pail Kids trading cards are probably still worth something. There may be someone in the world who would accept them as payment for goods and services. Does that make them a currency?

Does a currency need to be backed by some kind of country? Is there an expectation of stability of price? Do you need an area of economic activity where the currency is ubiquitously accepted as a form of payment? Maybe you know the answers to these questions. I don't. There are probably a lot of people in Congress who don't.

Though I don't remember Apple being explicit about it, it seems that their OS updates support the past 3 models. iOS7 was released when the iPhone 5s had not yet been released, and supported the iPhone 4, iPhone 4s, and iPhone 5. You can still buy an iPhone 4s, so I would expect that iOS8 will support it, but will not support the iPhone 4 anymore.

So you will probably be able to upgrade your current phone, though it'll probably be a bit slow and will lack some features. That's just an educated guess, though.
