Indeed. I write a lot of Objective-C code, and still drop into C++ for the CPU heavy tasks. Swapping out NS* containers for std::* alone gives a fairly high boost in performance.

All the C++ hate is blown way out of proportion. C++ is a great tool when you need performance. Tuning C++ isn't that difficult either. Contrary to what a commenter said above, steering clear of C++ at all costs is not what you should be doing. You should know when and how to use C++. It's useful more often than many people here seem to think. Especially if you develop for mobile devices.
That's a good question. Depends on what a record label is supposed to do. Some things that come to mind: Curation, publicity, managing (if not actually providing) distribution of recorded material.

Seems an MVP of a record label could start with next to nothing if you know how to promote on the cheap.

A more involved label might front a musician the cost of pressing physical material (CDs, vinyl) , maybe arrange tours (for those so inclined). Maybe help hire a decent producer when needed.

Anyone here work with or for, or own, a label?
It depends how you present the idea of adding machine-readable information to pages. After all, nobody is forced to do it, so you need to show some benefit before the "semantic web" will happen.

Schema.org is doing it with the SEO angle: mark up your pages like this, and they'll be presented better in search engines.

With VIE (https://github.com/bergie/VIE) we take a different angle: mark up your pages with RDFa, and they'll become editable.
I went to a talk by Yann LeCun [1] a few months back, "Learning Feature Hierarchies for Vision." The current state of the art in this field is mind-blowing to an outsider. The final demo was a program that he trained in a matter of seconds to recognize and distinguish faces of various random audience members, in real time, from different viewing angles.

I recommend Varnish (HTTP cache) where pages are returned instead of touching PHP. APC, a compiled PHP script cache and going to be used in PHP6 releases. Both should lower some resources required.

Most applications I see just reference-copy.

This article is really, really rudimentary, and not in the good ways. Why does it recommend "not copying data" without explaining references? Why is _Google_ recommending the use of bare mysql_query? I don't care if it's a toy example, they should be reinforcing best practices (or at least not-horrible practices) by using PDO or something similar.

Granted, most PHP programmers I know are not particularly competent. (I am, but I'm also weird enough to be willing to get competent with something like PHP.) But we can at least _try_ to hammer good practices into them.

The taxation of non-cash income has been a settled issue for decades (in the US).

They would tax Bitcoin receipts the same way they tax service-for-service or service-for-property exchanges. The government will calculate the fair market value of the services/property received at $X dollars (based on facts and circumstances such as the amount exchanged in similar cash-based transactions), deem the taxpayer to have received $X in income, and impose a tax of $Y on that deemed income.
And with a check or an American-style ACH payment (or British-style BACS payment), nothing at all. And both ACH and BACS provide many more services and essentially no practical downsides compared to Bitcoin. (Most people go through life never needing to make a payment anonymously.)

The thing is, people on the Bitcoin forums talk as if they have no idea how to set up a decent bank account. It's not hard. I do a substantial amount of banking and can't remember the last time I paid a bank fee. (Obviously you're correct that merchants do pay credit-card fees and thus that some of the prices I pay are affected by merchant fees, but I get services for that too.)
"Here in Vietnam you can buy a DVD of any recent Hollywood movie for 50 cents. Is it a coincidence that the domestic film industry is junk?"

Well I live in Sweden where DVDs/Blue Rays are quite expensive, but still the domestic film industry is still mostly junk. I don't think one factor has much relevance to the other ;)
Agreed. Said other bits in another comment, but:

-mysql_query()? BAD GOOGLE WEBMASTER, NO COOKIE FOR YOU. Seriously - there is no good reason not to use PDO, or at least MDB2. (Doctrine is better, but it's just a superset of PDO.)

-References are a modern PHP programmer's (quiet you, stop laughing!) best friend. "Don't use shortened variables because you'll copy data! Just reuse the $_POST['barf']!" Never mind that $foo = &$_POST['barf'] achieves both goals...

The statistics here seem more important than the individual cases. Not everyone who talks up penny stocks is long them either, but most of the people sending spam promoting various penny-stock pump-and-dump schemes have a selfish financial angle in doing so.

I'm not saying there's no reason to be interested in Bitcoin other than personal financial motives. The technology is legitimately interesting, but not nearly enough to have gotten the marketing push that it's gotten, particularly here. Only one thing explains that: the selfish incentives that the current implementation of Bitcoin provides. (Well, or extremist ideology.)
Agreed. You need to remember that all the stations are separate objects. So, on your techno stations, don't favorite soft rock. Oh, and pony up the cash for the paid service; it is worth every penny to not have commercials for business cards.

There's lots of factors why people might not be buying houses that have nothing to do with inflation: (1) it's not rational to buy a house when your abillity to meet payments looks undercertain; (2) it's harder to get loans; (3) there's been lots of media about people getting burnt; (4) we've exited the house-buying-mania bubble; (5) related t ofirst point butdifferent, you have much better labour flexibility by renting which is important in hard times.

You can already see evidence of this now. Houses are at
the lowest point in prices that they have been in
decades, but people still aren't buying, and they won't
until there's some indication that they won't ever be
this cheap.

"been in decades" - this would be true of Buffalo and Detroit, but certainly not of San francisco, New York, London, Perth, Sydney, Toronto, Calgary or other places I have an idea about.

I think first world property prices are still ridiculous.

It's madness to push people to leverage up in order to get into property just so they can store value. I'm not a hedge fund. I don't want to be compelled to behave like one to look after my savings. Now that the music has stopped, people are wising up that housing is not even reliable as a store of value irrespective of their sacrifices.

So some rough math shows that if you assume that the valuation of Groupon at $20 billion is based on that database of 56k merchants, you come out with an expected value of around $350k per merchant. That seems highly dubious to me, for a few reasons.

1. Many of these businesses are small restaurants, bars, etc. Notorious for going out of business.

2. The ones who don't go out of business can easily switch to other discount coupon providers.

Personally I've somehow ended up with way too many discount coupon providers sending email to my inbox. I suspect I'm not alone. Presumably I'm also not alone in the other behavior I see in myself - of those providers (Groupon, Living Social, Gilt Group, Bloomspot, Yelp deals, ... there might be more... I could care less), I am least likely to open Groupon emails.

So you shave .05 seconds off your PHP execution. Then I have to wait 12 seconds till the page is loaded, because front-end is not optimized at all.
We find that in regards to performance, C++ wins out by a large margin. However, it also required the most extensive tuning efforts, many of which were done at a level of sophistication that would not be available to the average programmer.

I am a fan of C++, so I liked the first part (that C++ wins, which is not really surprising). However it was not clear if the sophistication they talk about is regarding the Google's internal data-structures or the list of optimizations listed in Section VI-D? Many of these optimizations are not big surprises to a C++ programmer (where possible use hash_map, vector instead of list, initialize data structure outside of loop and try to reuse, and so on).

Overall, I do greatly appreciate the effort and their sharing the results.
Looks like twitter shut them down already.
Because if you don't provide a machine-readable description of your goods and services, somebody else will. And they'll get it wrong but you won't be able to get them to change it.
Interesting. I know the definitional difference between de and la and I know that de applies to indefinite things and so on. But the rules don't help here because to me (an English speaker with rudimentary French) la folie and la guerre aren't in different categories of definiteness to begin with. In English, war in general is just war, no different from madness in general being just madness. Thus I would never have constructed the sentence that way, and even after you explain it it still seems strange.

Once you tell me that la guerre is definite and la folie amorphous, then sure, I'd know to use the articles that way. But I would never have guessed this. It seems you have to know how the nouns feel to a French speaker; you can't simply compute the right answer from the concepts.
Well, that's great news.
I fail to see how that is addressing the problem stated.

The fact is that HTML5+JS is miles behind proper performance let alone cross browser compatibility.

Platinum should be shooting the lights out, then. There's only about 130 tons of the stuff mined each year (6% of the gold mined), it has more uses than gold (which increase the demand and reduce the supply as it's used up over time) as 50% of it is used for industrial uses, and it's sexier than gold - ask your girlfriend/wife if she'd prefer a platinum or gold ring. So if you really want a long-term store and one that is comparatively undervalued to gold, choose platinum.

Thanks for these. I read the article and thought "These are kinda basic..." whereas I just had to decide between implode and concatenation.

edit: in retrospect, what I was trying to say was essentially "Hacker news can write a better article on php optimization, just in the comments alone." Elitism? probably.
true, the warning is there for me whan I install my raplet, but it's not for when my contacts do, which would be the discomforting bit.

They're very different from amazon, google, and apple's current/coming offerings as they don't offer streaming on demand; they're a radio service. Even if there were 20 different on demand offerings, their business would still be valid as they're really selling their selection algorithms.

Ridiculous price, though. $1B? Seems very high for a service that only provides radio.
Dotcloud looks very interesting, but to me it's hard to consider next to strong competitors that have established their pricing... That said I'm very looking forward to see the dotcloud pricing announced.

Looking a bit closer:

1) "Take x, add 2 and add that to x" the second add should be "set x to that".
"Which is one more step." It is the same amount of steps, just a difference in how it is represented to the end user.

2) Hmm, never thought about that type of connection before. In my experience I had many years of "x = x + 1" in both Algebra class and when first exposed to Basic programing. I didn't encounter C (first exposure to extended operators) for at least another decade.

Whenever I see such an assignment statement I visualize this in my head...

x = x + 1
x = 5 + 1
x = --> 6 <-- (woosh)
x <---6 (woosh)

OnSwipe has made my iPad browsing experience significantly more infuriating since it forced itself on scores of unwitting Wordpress blogs. If your blog is hosted on wordpress.org, please test it on an iPad. If you can't do that, at least disable OnSwipe until you can.

Of its many annoying quirks, the worst is that it makes scrolling really choppy. On a tablet, this is utter UX fail. It also strips your blog of any unique design. And the link to switch to the standard site rarely works.

I am stunned that there is so much enthusiasm for a product that creates a problem while solving nothing apparent.

The problem with possible optimizations and tunning is that it requires constant effort. Projects often have serious deadlines and you simply can't constantly think about memory or allocation footprint and still do a good job in the amount of time you have, unless you're well above average.
Yeah, I've since found out about the 'divisible' aspect. Don't understand it yet. In particular, how different people can own fragments of one cryptographic unit, without there being any central coordination point.

As for storing in the cloud, uh, no thanks. Recent cloud upset providing an entirely expected illustration of the 'nothing can possiblie go wrong!' principle. Not to mention the mooted Internet Kill Switch being also a Cloud Switch.

One of the interesting details is that Go Pro required 786 lines of code as opposed to 850 lines of C++ code and 297 lines of Scala Pro code. Regular Go code was 902 lines. It certainly doesn't look like Go scores any expressiveness points over C++.
Keep in mind that since C++ is usually used for performance critical code, its compilers are often highly tuned and produce good code (see Intel's ICC for number crunching code).

A less popular language - or one that is usually used for less-critical code - will suffer.

C++ wasn't always so fast. See Kernighan and Pike, "The Practice of Programming" for a simple example where Java surprisingly beats C++.

It may just be because I've been writing a ton of C++ lately, but to me the C++ data declarations are the most readable of the bunch. The stuff with iterators is much uglier, of course, but so far I like the syntax of C++ a lot better than that of Go.
