You might appreciate "Life: The Movie" if you haven't already read it.

The author details the ways in which entertainment has become the metric by which many Americans judge their lives.
>> "S.F. is a great city to just hang out in. Amazing food, great weather"

Great weather? really? Seems like it's often very windy and cloudy to me. The amount of fog around is just bizarre as well.
@cageface really? you can't refute my point, so you instead try to correct my spelling to make yourself look smarter?

Your point is purely rhetoric.

Does GNU invite being pitted against its namesake by hardcore oldtime Unix fans?

Still, focusing on whether 'NOFOO' name is appropiate or not is quite silly.
Apple is now suggesting that you use three-character class name prefixes, since they claim all the two character ones.

So you saw that talk at WWDC as well? Every engineer from Apple that I've spoken to and asked about this has gone "What?! Did he really say that? Ignore it. We don't recommend that. Not at all."

Seeing as you're writing ObjC using a compiler I've worked on, I think that probably understand the "low level shit" better than you do.

You work on LLVM? Props to you, if so. Thats an awesome project. However, if you work on gcc, I haven't used that in over a year :-)

(I kid. Props to you, either way. I can't do what I do without what you do.)
It worked nicely on my Incredible ;>
There's a huge difference between the overhead of a dynamic function call and a vtable lookup. No doubt there are some cases where even a vtable lookup is too expensive but there are millions upon millions of lines of production C++ in high-performance apps that use C++'s vtable dispatch.

What language would you choose to write something like Protools, Photoshop, Maya, Visual Studio etc in? Definitely not C and definitely not Obj-C.
I believe I have seen this at Huffington Post weeks ago
Remember, it's Apple, no dissent is allowed.

Frankly, most companies would probably do the same thing. You wouldn't want a highly negative thread in your forums. That might make potential customers question their zeal and wait for the next model before they make their purchase. Definitely not something you want if you're in the business of releasing new phones every year or so.
So? Apple is a company that tries to make money. It's not a goverment funded organisation that is founded to serve its users with a fair and allround content.

If Apple decides to delete those threads than they should be able to do so.
They have a hugely loyal user base. I think they have their attention whenever they want it.

They where clearly running this as a bit of customer development. They had no idea what people would pay, how many people would pay, and whether or not the thing would work. Their goal right now is to put some numbers around those metrics and see what they get.

After all, they're part of Conde Naste. It does seem rather strange to be donating to a site with such a huge backer behind it.

I think you'll see them roll out something much more sophisticated in the coming months.
Mel's Diner - We need your help to bring Mel's Back
What is Clojure performance like? I checked with http://shootout.alioth.debian.org and haven't found it there. We're doing some lightweight geometrical computations like figure intersections, etc (queued, not real time) and we built them in JRuby just for fun (JVM is a requirement here) so I'm wondering how would Clojure perform there.

I'm asking here because I don't know a bit of Lisp so I can't just quickly code a benchmark. Thanks!!
lol.....i am still trying to figure it out, maybe its German humour!
No one said they shouldn't be able to. It's interesting that they chose to though.
If you choose to attack someone's intelligence instead of presenting a factual counterargument then it behooves you to get your spelling right.

So again, how can you be sure that the reference you just released isn't the last live pointer to some huge datastructure that now has to be torn down reference-by-reference?
Interesting problem space, but not the only valid one, nor the only one likely to give one a sustainable advantage in the commercial space. In fact, there's probably more to be made in developing a heart-friendly Sachertorte-style dessert (trademark would keep one from calling it by that name) with an icing that is as good as or better than the original and marketing it (and a cookbook full of recipes that don't include your magical icing) via a twenty-minute PHP "project".

HNe is not about the outer reaches of computing possibilities (although the subject tends to interest most of us, and if you pay attention you'll find that Shannon is familiar to at least a significant subset of the population here), it is about creating and capitalizing on value. It is about marketable innovation. Nobody is likely to win a Fields or an Abel for finding a way to make $9.95/mo from a few tens of millions of people, but whoever does it is likely to drive a much nicer car than the guy whose life's work is able to pluck useful security intelligence from a billion digitized telephone conversations a day (but, since it is classified as top secret ordnance, can never be marketed). And if you want to be realistic about it at all, anything that approaches the limits of the IR noise floor with precision, even limiting the problem space to text, is going to be so classified. The work may be the source of great personal pride, but little else. (And when the fifty-year window opens, you'll be too old for a Fields.) So much for entrepreneurship.

Well, if we're talking about different hardware, this whole discussion is moot - CPU (not C-entral anymore..) architecture changes render "old" optimization techniques only situational today.

At any rate, the same is true for all languages, and _delirium's point is spot on: it's not the language that matters, it's the fact that bad (or slow, or inefficient, call it what you will) code is encountered regardless. It's time we stopped language wars, don't you think?
So you saw that talk at WWDC as well? Every engineer from Apple that I've spoken to and asked about this has gone "What?! Did he really say that? Ignore it. We don't recommend that. Not at all."

Regardless of what they say, Apple is still claiming new two-character prefixes, including the one I've been using for years.

You work on LLVM? Props to you, if so. Thats an awesome project. However, if you work on gcc, I haven't used that in over a year :-)

I'm a big fan of LLVM, but no, I've done nothing with it. That said, if you're using clang for your production builds, you're a much braver soul than me.

There are still plenty of codegen issues, especially in the new iPhone/ARM support. There's a reason Apple is still using GCC.
"Supermarkets (in the real world) that prevent you from comparing products on price, by putting items in different sized bundles."

At the HEB grocery stores in Texas, every price sticker includes price/ounce or price/count. I was surprised by how often buying in bulk is more expensive. Take eggs for instance, there's a 50-50 chance that eggs in the 18-pack will cost a few cents more than the eggs in the 12-pack.
I don't know about that. I read and discuss algorithms in the Wilmott forum. http://www.wilmott.com/index.cfm

There is actually alot of useful traffic that goes on there. Having said that, the Wilmott forum acts more like mathoverflow than stackoverflow in it's non tolerance for basic questions.

Arguably if Oracle was free we'd not be having any of these discussions.

That said, there's still some stuff to be learned from things like BigTable and Dynamo that simply weren't considered when building Oracle due to CAP. I'd wager that what you're seeing now is the dark ages of where we regress back to infancy, forgetting the lessons of the past (throwing out the schema? really?) before someone comes along and solves the root problems correctly.

Edit: Oh, and to your other point about tradeoffs. I'm not saying there aren't tradeoffs involved. The point is, the "tradeoff" should be "oh, please configure this table to not support custom WHERE clauses by materializing it into a simple K-V store. Thank you Mr. Database", or "relax consistency here so we can have availability across data centers on this table, thank you Mr. Database." But these should be easily described and diverge from the default, ACID-compliant, normalized, schema'd, and relationally-queryable data storage.
Degraded call quality and dropped calls are a consequence of signal attenuation. If the antenna experiences abnormal (normal being defined by typical behavior of competing devices) attenuation, then you will experience call degradation issues under conditions where your signal strength is not optimal.

Do they store any of your information?

They have access to:

This observation explains 99% of political debates. Everybody is making points that don't necessarily support their own anecdotal biases, but they keep charging ahead anyway.
That's not a great analogy. Using cheaper components to cut costs requires more engineering effort; this is a form of optimization. For a prototype, you might just use more expensive components if it's convenient, since the per-unit cost doesn't matter much.

When writing software, there's no direct analogy because usually the components we build our programs out of have hardly any per-unit cost. We don't save any money by using a crappy third-party library over a high-quality one. Using a library with lots of unnecessary features may be cheaper both for prototyping and for the final product.
I wouldn't use the term "interesting" so much as "foolish".

Much like Best Buy's recent firing/non-firing of that employee, the act itself only serves to add more fuel to the negative-PR fire.
It all depends who you associate with. If I only hung around with techies / startuppers I think I'd have to shoot myself too.

I'll take my "high in the desert" people over your "high in Williamsburg, Brooklyn" people any day. I agree that a lot of Burners are deeply annoying, but the core people who actually make it all happen (or the larger installations and camps) are often incredibly interesting, intellectually broad people, doing it all on a shoestring. If you think you're doing a lot with your life being in a startup you're probably not doing half of what they do in an average week.
I enjoy playing Skat, though I only play a few times a year, we usually need some relative visiting to get a game going. I also like playing Catan and Backgammon.
It would be nice if on the front page they addressed my privacy concerns in some way. I live in my Google account (gmail/docs/analytics, etc) and I'd like to know what information the app is going to have access to.

Something like Android's pre-install screen would be nice.
I tried to convince Isaac to include Clojure in the benchmarks. He will probably include it once Clojure 1.2 (which has implications for performance) is released, provided that all the benchmarks are ready.

Generally speaking, I found the following to be true:

Java < Scala < Clojure < ... < JRuby.

Clojure is relatively fast. It really depends on the program at hand, but in my experience, having to REALLY generalize, it's at least an order of magnitude faster than Ruby/JRuby.
The weird thing about S.F. is that the weather can vary tremendously from neighborhood to neighborhood. The Mission can be sunny any day of the year. The ironically named Sunset is almost always fogged in. We also seem to get our seasons backwards here. Summer tends to be cold and foggy but Sep-Dec can be beautiful.

It's not exactly San Diego weather here but coming from anywhere that snows it's pretty friendly.
The beauty of Creative Commons is that the more stringently copyright is policed the more the public will have little option but to engage with media under CC licenses.

People naturally want to share things which they find entertaining with their friends, and I see this as a psychological trait which is hard to suppress and isn't going away any time soon because it's a fundamental aspect of human culture. In a theoretical world of perfect copyright policing the only way to stay fully engaged in cultural exchange will be via media with CC type permissions.
It depends on what sort of image the company wants to uphold. Do they want to be the company that goes out of their way to protect the rights of their customers with some less than perfect products, or do they want to be the company with perfect products that uses its customers as a means to its end, nothing more, nothing less?

I doubt many people on the Apple forums weren't aware of the issue. Deleting the thread simply gives them more negative publicity.
Why Friends Matter at Work and in Life
This post reminded me how I always was kidding on my coworkers and friends. When working both on the same PC and needed to download some utility. I was going to Google homepage and typing:
"Dear Google, please help me. I looking for some information regarding this utility program, called XYZ. Do you, by any chance, know where from I can download it? Thank you very much in advance!"
"Without customers", do you mean operating solely on proprietary capital? Or does it mean "no customers, yet"?

(Please pardon my ignorance in this matter.)
Congrats on the launch guys! Do you have anything planned for Android? The reason I'm not mentioning iPhone here is because Android's default/primary contact list is in GMail, so it would probably make sense to integrate into Android contacts app and their alerts?

Ballmer says a lot of things. It has been years since Microsoft has successfully followed through on its intent to become a leader of some new industry. Even the Xbox, after ten years of investment, barely shows up on Microsoft's balance sheet, and I can't think of anything they've launched since that has had comparable success.
Yup, I have seen it too. They have it in quite a few sites. Its actually quite common. Not sure whats the deal with this guy.

We (nearlyweds.com) are a beta customer of Kiss. We use GA and Kiss right now. As much as I love GA, they do a crappy crappy job at tracking via conversion funnels, in fact it's almost useless for our business. The real story is that Kiss tracks people, not just visits. This gives us clarity and insight into our conversion funnels, which paths convert the best, which referral sources convert the best, and then on the back-end, because they track people, which sources produce the subscribers that last the longest, etc. We can set up funnels for just about anything.

There is also a psychological element at play here that has been interesting for us. When the product was free, we didn't prioritize optimizing our funnel aggressively. Now that monthly fees are looming, we are having to fish or cut bait and get real serious about which funnel projects to pursue or not to pursue. It's a very healthy restriction on our business (a la 37signals).
That's a very dangerous line to cross - ranking search results by, essentialy, ideology?
Very clever. I don't know who makes the stuff, but since childhood I associate that brand with innovative ad campaigns. Besides the good-natured absurdity of this one, issuing some unique versions strikes me as the modern equivalent of branded trading cards - generate buzz for your product as people spend time ensuring that they've seen them all.
He took on gravity... but did gravity win?
It means "trading their own money". "No customers yet" is actually worse than having customers, since you need to worry about actually finding them in addition to making money for them.
Not at all. It's in portuguese, tough.

Ask HN:  What is entry level in the web development world?
Bear with me, this might be a little long winded . . .

I have been doing freelance & startup work for almost two years and been mildly successful -- two companies I've been involved with (one heavily, one lightly) have been acquired, and I've got really good references.

Despite this, circumstances have me looking around for a full-time gig. Being both an HN and Rails enthusiast, most jobs I see tend to be of the startup-style, "wear a lot of hats and hit the ground running or else things break" variety. The problem is, over the last couple years I've found that I value a little security and time-cushion to learn and grow more than these jobs seem to have room for.

Out of college, I went to work for a Big 4 accounting firm in an IT specialty group. I had no idea what they even did when I was hired, but in two years I was a high performer. This was almost entirely due to the training and mentorship programs that existed within the company.

The hacker ethos exalts the autodidact. I taught myself everything I know about web development up to this point, but I'm now frustrated because my pace of growth is so much slower than I know it would be with a good mentor. I am a mediocre autodidact but a top tier learner in a classroom or mentorship situation. In the Big 4 Co., I got to where I did by asking tons of in-person questions every day. The web-forum/ Stack Overflow / IRC method of getting help pales in comparison.

So after all that, here are my questions:

Is it possible to get this kind of experience as a developer?

If so, is it possible to get it and work with cool tech?

How much is a lack of CS degree going to hurt me? I'm guessing that credentials are more important the more "secure" the job is.

How much should I study up on verbal CS interview puzzles, which I loathe and suck at?

To sum it all up: what exactly is an entry level position in web development, and where are the best places to work that actually have them?
I couldn't really get my family interested in Dominion - a little hardcore for them. Catan & poker seem to be the best bets, and Ticket to Ride works well.

I kind of want to try making my own game, although with so many unfinished side projects I'm not sure if I'll find the time.
That said, if you're using clang for your production builds, you're a much braver soul than me.

Hardly brave; I only use it personal projects (which target 10.6/64-bit Mac) and debug builds. Release/Ad Hoc/Distribution builds for what I work on uses llvm-gcc. But, I'm not responsible for those builds.
While I think those "German engineering" cliches are rather tired (and wrong, cf. Dieter Rams influence on Apple products), I don't see a big difference regarding complexity between Cappuccino and Qooxdoo regarding complexity. Both seem to embrace the desktop paradigm, both have an API that's close to traditional GUIs (very close in the case of Cappuccino).

(And it's not really that much easier getting graphics-intensive stuff done in Cappuccino, compared to something like Raphaël.)

Cappuccino just looks better by default. It shares this advantage with ext.js, compared to the e.g. Dijit (and qooxdoo). Whether that's actually worth that much is a good question, considering that any respectable outward-facing webapp is bound to have a style of their own and plenty of designers to make that happen. In that regard, I thin Cappuccino might be even more suited to intranet enterprise applications, where there's not that many designers around and having a default good look is definitely worth it (and having things look like a desktop app is actually an advantage).

In the end, the big difference is between the desktop way of doing things the more common jquery/dojo/YUI enhanced-web page style.
I've been meaning to write about this one day. There are some
things that change. For example, you learn to distinguish problems
that can be solved with money from those that can't. You can buy
your way out of a lot of schleps.

Life doesn't get an order of magnitude more enjoyable, because you
still can't buy your way out of the most serious types of problems,
but a lot of annoyances are removed.

The best part is what I thought would be the best part: not having
to worry about money. Before Viaweb I'd been living pretty hand
to mouth, doing occasional consulting. It felt like treading water,
in the sense that while it wasn't hard, I knew in the back of my
mind that I'd drown if I stopped. Getting rich felt like reaching
the shore.

One thing you learn when you get rich, though, is how few of your
problems were caused by not being rich. When you can do whatever
you want, you get a variant of the terror induced by the proverbial
blank page. There are a lot of people who think the thing stopping
them from writing that great novel they plan to write is the fact
that their job takes up all their time. In fact what's stopping
99% of them is that writing novels is hard. When the job goes away,
they see how hard.

I think the idea is that, if you're careful, you can avoid situations like this with a reference counting scheme.

With a garbage collector, there are more things that are out of the developer's control, like when exactly the garbage collector will run and for how long.

C languages don't magically always perform better than other languages, but they do give you a greater level of control over what happens when. Whether that's a good or a bad thing is up to you.

All too often this is the naive apologists cry: "It's their foo. They should be allowed to do with it whatever they want." It's a true enough statement, but it stumbles spectacularly wide of the point. Don't mistake the right to do something with the judgment of whether or not you should.
I'm totally not following here...

How can multiple insert statements be considered duplication if they are inserting different things to different tables?
My apps have multiple insert statements. They also have multiple calls to "print". Do you count that as a duplication as well?

We can continue the discussion by email if you prefer. It is interesting to me, but we may be getting off topic.
I'm surprised that the Monster section was about their AJAX performance. Theirs is a notoriously slow .NET implementation. The far more interesting performance problem is scaling their contextual search engine (acquired with Trovix.com).

I don't have enough hours in the day to go to all the film festivals, concerts, author readings, dance performances, gallery openings, and other similar events that are occurring all the time in SF.

If you're looking for people who are interested in things outside of tech, you should start going to some of these events, and meeting people. Join the SF Film Society, for a start! Maybe I'll see you around...
