> One thing I think is tiny, but incredibly helpful in Ruby, and I don't understand why more languages don't have it - the ability to add "?" and "!" to operators. That's an actually useful convention.

My primary languages are Ruby and C. After working in Ruby for a while and then switching back to C I often find myself naming predicates with a trailing _q. I don't have an equivalent for !, though.
You might be surprised how well you can sell things by shutting up, listening, and addressing your customer's concerns directly rather than making a lot of noise.

There seems to be a recent meme around HN lately that you have to be a "hustler" to succeed. I think that's been misinterpreted a lot. Most of the hustle is in showing up, staying alert, and then applying just the right insight that will let your target know that your interests are their interests.

As recently as last summer, I felt that I had to make a lot of noise to make my ideas heard. I got nowhere. Instead, I've found that by listening to other people's ideas and then carefully suggesting ways to improve them, I end up with far more influence over how things actually turn out.
In C/C++, I was usually in the habit of adding "Is" in front of predicates. "something.IsDone()", "something.IsOver()", etc.

One of the devs here. It's definitely not intended to be a new language. My understanding is "text/traceur" was chosen because some of the features haven't been accepted officially into harmony yet (i.e. they are strawman proposals: http://wiki.ecmascript.org/doku.php?id=strawman:strawman), in particular classes/traits and async.
I'm considering of doing the same thing. My main motivation is to meet interesting people working on interesting stuff.

I am not talking about making noise. But it's pretty obvious that you can't sell anything if you don't make people aware of it's existence.

You can't be a quiet salesman, you can use silence to sell, but that is very very different.
I turned down a job at Google (not 300k but hey, it's Google!) to join a startup. The startup started to sink about 2 years later.

I learned a ton and didn't regret it for an instant. Moved on to a new startup 2 years ago when it became clear the first was a dead end. Google recruiters continued to ping me religiously every 6 months regardless.

Moral of the story: Google, MSFT, Facebook, etc will all still be there in 2 years. Especially if you're early in your career and don't need the cash today, go wherever you will learn the most.
Same, I was somewhat hoping the title was a typo and meant to say "iPad".
For those who don't know, Kyle Tress is an athlete, a skeleton slider to be more precise. I had to look this up, since the causal use of the verb "sliding" totally confused me. I was completely unaware of the existence of this sport, so ... one thing learned today already.

Exactly. All the time while I was studying I've lamented about contributing to open source, especially to the kernel. I've read tons of things, code, os books. I think I've teached myself a pretty good understanding of how it all works (never taking a os course at the university, majored in math).

Not a single patch came out of it over the course of almost 10 years (taking the time into account I dabbled around in Linux in high school).

Then the massive linux graphics stack rewrite broke my laptop. I've had no clue. Zero. Nada. But I've tried to fix it and actually succeeded somewhat. Then I've noticed that other stuff isn't working anymore in the new graphics stack (it was an old machine and devs were busy porting the newer chip generations). So I've started with more serious stuff. In retrospection, re-reading old mails and patches my lack of clue about the code, process and people is hilarious. But pretty soon some fools started to use my XVideo implementation (despite all the bugs) and reported problems. And I just wanted to get my laptop back into a working order with the cool new linux graphics stack.

I've had a reason to ship and users that bugged me. So I've shipped.

Now, two years later I'm a major contributor (even managed to once get a top 20 position by patches for a kernel release due to a major cleanup). In a specific area (Intel graphics memory manager) all patches are either reviewed by me or written by me.
Which font color is best for the eyes?
That's a fair point. Would the AST strawman proposal (http://wiki.ecmascript.org/doku.php?id=strawman:ast) get you most of the way there? If nothing else, it would make some metaprogramming of the source tree possible. Combine that with module loaders (http://wiki.ecmascript.org/doku.php?id=harmony:module_loader...) and I think you're pretty close to macros.
..and by making photography easy, fun and simple to share, Instagram encourages practice, which then increases the user's skills. It's an awesome feedback loop.
This is great content. I really wish someone had told me about the point of focusing really hard on the first (and often trivial) project you're given when I first started. I've only been in the workforce a year, from a business degree at a large bank, but these laws still apply.
What's interesting is that now the mobile apps are available for free users, I'm sorry to say that they are going to lose I little of my money as this was my primary reason for paying for spotify.

You're right, it isn't about living longer. It's about our cognitive abilities, perhaps.

Using your metaphor… I think, variable X is going to infinity _in both cases_. It's just that we operate in an environment where the infinity equals to what is a finite number (two or three digit integer) in another system.

Another way to put this: One can't experience anything except one's life. Therefore, life is infinite to person's subjective experience (the only experience available).

EDIT: Okay, I think I see where we disagree. In my view, while what you perceive may not be the "reality" in some absolute sense, it is the only reality for you nevertheless. And your death doesn't exist there, much like dragons or wizards. In short, yes, the fact that you can't perceive your own death means that you don't die. You seem to have different point of view.

There are a lot of people in the entrepreneurial community who jump up and down and say "Look at me, I'm an entrepreneur, this is what it means to be an entrepreneur, ideas are worthless execution is everything," etc.

There are also a lot of people in the entrepreneurial community who don't go to startup events because they're at their customer's offices, showing them how their products can help them.

The second kind is the quiet professional.
I'm on the Traceur team, but I don't speak for all of us (or Google). Personally, I think macros would be really cool, but they're a challenge in a language that isn't homoiconic, has both statements and expressions, and a pretty complex grammar. I don't know if it would be possible to design a general purpose macro system within those limitations that was usable by mere mortals.

I see macros as being useful for two things: 1) DSL-type "make my own inner language" stuff, and 2) conditional evaluation. JS is already pretty syntactically flexible, especially with object literals, so that covers some of (1). JS already has closures, so if we can get a nicer function literal syntax, that makes it tolerable to do (2) just by passing functions around (and it's more explicit, which is good to some people).

This is a very hard topic to compare to Kyle's experience. First of all, Kyle is already given an audience and the success is evaluated by some metrics about his psychical performance. While marketing, you have to create an audience first. Once you're visible, you can choose be silent or keep making noise. But, usually, this is not the case with startups.
Sorry but that is simply not true.

In order to get into that office it requires quite a lot of work and a lot of making people aware that you exist.

If you ever worked with sales you would know that there is no such thing as a quiet sales man. That doesn't mean they are noisy.
"You can also create your own iterable objects. Normally this is done via the yield keyword (discussed below in Generators) but it could be done explicitly by returning an object that has __iterator__"

This clearly seems to be borrowed from Python; even the double underscores are present, which looks a little odd in javascript.

Flipkart vs Infibeam : Customer Service
I ordered a book each from Flipkart and Infibeam to test how Cash-on-delivery concept works. Instead, i saw how different these 2 companies are in terms of Customer Service. The shipping (AFLwiz) provided by Infibeam is the worst i have ever encountered. 6days and the package is still lying in AFL's center hardly 6km from my place. After numerous calls, i decided to write a post and spread the message around. Avoid infibeam. I didn't pay a dime to them (Cash on delivery) but to the ones who prepaid the amount, this is a stressful exercise.

I know this is your choice. But seriously.

Why not pay for such a great service? Why quible over such a low price?

You might be different than most people. But paying 20USD for a couple of bears and drinks is nothing yet when it comes to pay for music ad libitum people suddenly become very aware of their money.

I am not casting any blame, just interested in why people rationalize like that.

Ultimately, even though every company might be challenging the patent system, they will look forward to do so without any damage to them.

Music, Sound Effects, Tiles, and 2D Art to Use in Your Games
In non-tech cases, my impression is that upstream billing isn't taken as solid proof of the amount of damage incurred. For example you might have a very expensive contract with a visits-your-house personal mechanic who you've agreed will be your exclusive car-repairer. Thus when you're hit in an accident, you automatically incur a large bill of $X, due to your pre-agreed subscription with the mechanic. But for either civil or criminal damage computation, a court would normally determine how much damage was caused by looking at what the repair cost would've been with a "normal" mechanic at prevailing rates instead.

The reason why older people 'cling' to old ideas is that as we age our neural pathways become calcified along current paths and connections, making it more difficult to change our minds about something. If aging were inhibited, presumably that problem would be one of the ones solved as well, so people's minds would remain as agile and flexible as they were in young adulthood, indefinitely, and hence able to change and adapt new ideas.

That's quite a leap of faith, IMO. It might be so that clinging to old ideas is a chemical "problem", or it might be how the brain works.

When studying other people, I come to the understanding that around 30 years of age, many people have decided on an ideology, decided which music they enjoy, what food they like, and many other interests. When presented with new information which might require change in that internal model, many people seem to ignore the new information rather than changing their model, because changing our internal model is hard, and it becomes harder the more elaborate our model of the world is. So, the older we get, the more elaborate our models, and the more reluctant to change we grow.

I'm know people are different - I am fighting this kind of stagnation in my mind every day - but I'm not convinced that the people who are most likely to become immortal are the ones that are the least prone to stagnation. I'm afraid it's quite the opposite.

A quote on Startup
Startups win by doing something small, really really well. Usually 10 features does not sell better than one good feature!
Wrong.

Being a quiet professional doesn’t pay off in the real world, aka our market-driven capitalist economy. Soldiers live and function in what is essentially a socialist culture with rigid, strictly enforced rank and class structure. Hence the refrain: “What the hell do you think you are, soldier? An individual!?!”

I’ve lived & worked in paramilitary cultures myself. They all have the same characteristics: Be a quiet professional, don’t make waves, conform, fit in, don’t question authority.
And when you’re getting shot at in Iraq or running around fighting forest fires (like I was), this makes sense.

But in a dynamic, entrepreneurial economy where people all the time come out of nowhere and make a name for themselves, being a quiet professional is sure path to peon-hood or, best case, middle management.

If you want more than the default station in life you've been handed, you gotta make noise and alert the world to your presence, it’s that simple. Either that, or you can play by the rules and hope that the man actually rewards you.

Those SEALs kicking doors, those Marines taking bullets, they do it so that people like you and me have the freedom to make noise, create new things, and maybe, if we’re lucky, make a small dent in the universe.

But they don’t do it so we can be like them; Because their world is more Soviet than anything else in the US of A.
Ask HN: A good online refresher for reading Mathematical notation?
Hi all,

Does anyone have any recommendations for a good basic guide to reading mathematical notation?

I've been playing with various things recently and reading a lot of academic papers on various topics such as cellular automata and vision systems and such like. However invariably these papers document their solutions using 'proper' mathematical notation.

While I can understand most of these concepts, I appear to have forgotten what all these squiggly symbols mean. Any suggestions?

Depends on how you define the immortal part. For example, my disk drive can't be immortal, but with proper care, the data contained on it can be.

Does data-dumped me count as immortality? I think it should. If you eliminate all the wacky religious stuff people believe in (though I assume most HN'ers are atheist), aren't we just big biological stores of information?

If so, "you can't die no matter what you do" is essentially true, in that you could be restored from a recent backup -- the same way as when a hard drive fails.

1. Yes. They might. The thing is, the politicians are much more likely to be immortal than the soldiers.

2. Yes, I agree that would be pretty sweet. Einstein was conservative too, though. It seems to me he refused to accept quantum physics because of a stagnating mind. I might be totally wrong.

3. I think we might become better at avoiding to repeat bad choices. I also think a lot of the people in their 20s who think immortality is just great underestimates the changes it would entail to human culture.
