Yay, loosening regulations on wall street. Lets let startups without enough financial knowledge and market power to create a real IPO jump into being publicly traded.

I see this going really well.
It depends on how fast you're growing, since technology keeps chugging along too.

One of the best things of a program like Udacity is that Udacity is free to quickly iterate on the curriculum to make sure it meets the needs of employers.

I've never heard of universities going to talk to companies that employ their alumni to learn what they could be doing to better prepare students. Udacity can do just that because it's part of the same ecosystem where its students are employed like Stanford, but it will be free from the bureaucracy of an academic institution, a luxury Stanford doesn't have.

This is a false dichotomy. There is much more opportunity out there than working for MegaCorp or overhyped low-paying RoR startups, especially if you have the chops.
Not really. People often talk about the Internet democratizing lots of things (music, news, etc.), but you have to pay for the Internet.
This was the next item on my list to hack on this week. This is awesome, I'd love to see more apps use these, I love pinned tabs in Chrome but I lose info.
Actually, they switched to Lucene.NET a year ago: http://blog.stackoverflow.com/2011/01/stack-overflow-search-... It sounds as though the search indexing isn't done by the database server anymore.

Awesome. Really dig this. It's simple and easy to implement. Good work.
Changing the title bar is ineffective; you either make the title blink between two states which is a blaring annoyance and terribly distracting (GChat), or you just add a modest little (1) that is hard to see (Facebook). I think the favicon is much better suited for this function; it conforms to what people are used to with mobile phone UI.

However, the problem with this library is it has to follow the limitations of favicons' dimensions. I think there should be an open standard for having alert badges like iPhone and Android phones put on top of home screen icons. The browser distributer could design theirs to match the UI so people could recognize them, and they could be allowed to extend just 2 or 3 pixels past the normal favicon boundaries to grab attention without being annoying or invisible.

You can tell when people want something when they're settling for several make-shift approaches at it within limitations.
Brilliant! One problem I've found is that it can't handle icons larger than 16x16 (it crops them).

Chrome has a desktop notification system similar to Growl. Not sure if Firefox and others implement it. I much prefer it over the titlebar modification which I just find plain irritating.
Excellent stuff. I find the best javascript micro libs are built with one specific purpose in mind, like at work or on a startup, then extracted out and open-sourced :)

I'd suggest adding a config option for how to handle certain digits or multiples - personally I would prefer to have 1..20 and then 20+, 30+, etc. because they're easier to grok at a glance. I guess that could be wrapped into it pretty easily for any given use case though.

I used to have that activated for GChat but got tired of it. I think it's more annoying than the title bar, but at least you can turn it off.

Alerts should be there when I want to look for them - they shouldn't pull me out of what I'm doing. If they have to pop up on the screen for me to notice them it probably means I'm paying attention to something else.
Use traits and you get this for free, without implementing all the plumbing yourself.

Inheritance has its place in game dev though. It's just that your hiearchy needs to be designed in the space of what you are actually building: not vehicles, weapons, and monsters but renderers, physics, AI, GUIs, etc. And you want to figure out how that stuff is going to work before you break it up into classes.
>To protect themselves

From what? People actually using and improving their drivers?

>to protect their IP

What's the fucking point? What is there to protect? It's what I don't understand in the first place.

>and to save time and resources.

I call bullshit. Opening their drivers would save more time and resources than they could ever hope to save by keeping it closed.

>Good documentation takes effort.

It takes much more effort to reverse engineer stuff. If you can't be assed to write documentation, give us undocumented code (side note: why are you writing undocumented code in the first place?). It's still infinitely better than keeping them closed. Everything is better than keeping them closed.

>Plus, have you seen the pattern that played out with the open source drivers for ATI cards? "Oh, if only those ATI bastards would release documentation!" (ATI releases documentation) "Oh, if only those ATI bastards would release example code!" (ATI releases example code) (etc)

One bad example doesn't prove or disprove anything. As a counterexample, look at the excellent Intel Graphics drivers for GNU/Linux - by far the most reliable graphic drivers I have used; nVidia doesn't even come close, and let's not get started about AMD/ATI. Free and open drivers are still infinitely superior to keeping them closed.

>This went on. By that point, it doesn't seem like a loss to not bother.

How is open sourcing something a bother? It's much more of a bother to keep them closed, for everyone involved, users and developers alike.

>unless you're suggesting they could fire the driver team and have the open source community do their work for them.

I am suggesting that the driver team should not, by any means, be the only ones with access to the source code and the right to fork, modify, fix and improve it. It's stupid and inflexible, and that's something the hard- and software industries have to learn already.

Good question. I just googled this: http://en.wikipedia.org/wiki/RAID#RAID_10_versus_RAID_5_in_R...

Summary: Slight benefit to read performance and greater resiliency in the case of drive failure with Raid 10.
The problem with de-duplication is that it actually takes resources to do that. At the rate we're serving requests, everything has to go as fast as possible. Normalizing can actually slow things down.

Our app is not quite the typical web app. we can't cache much, we serve 8-9 digits api request every day and we try to do it as quickly as possible. Every request is different and unique.

And don't worry, I'm not insulted :) Hopefully this conversation will give some insight to people about how we do things.
While I appreciate a good piece of code and the need to reinvent a wheel

That reeked of sarcasm.

There are two problems with OCSP stapling:

* It requires some configuration on the server side. So it probably won't be enabled for the great majority of sites until some future generation of upgrades enables it by default.

* If a MitM presents his evil server to the client, he's just going to opt out of sending the stapled OCSP response. So the browser's back in exactly the same situation where he has to block for 1 whole extra second to do traditional OCSP (and has the same hard decision to make about what to tell the user if it fails).

EDIT: Which is not to say that I don't think it's still a great idea. It just would have worked a lot better if it had been the original OCSP mechanism.

RAID-5 and RAID-6 suffer tremendously in their degraded state - instead of being able to read individual blocks from a single disk, you need to read all the disks (or all by 1 in RAID-6) for any blocks stored on the down drive.
Another very good reason to get rid of the unreasonable clusterfuck that are patents. Once and for all.

And magic is there to be shared. I can't even begin to imagine where we, as humanity, could be if people shared their results and benefited from incremental development off each others' discoveries instead of spending uncountable man-hours reinventing the wheel for the seven hundred and three billionth time.

It's still pretty expensive for archival storage without instant access requirements. Can somebody please do a tape based cloud storage service with slow file access but much cheaper per TB storage costs?
Those drives still cost about 20k or so to purchase, for only about a 25% increase for reads and 10% for writes (http://blog.serverfault.com/2011/02/09/our-storage-decision/) why would we pay that extra for so little gain?

Also, with FusionIO you are putting all of your eggs in one basket - drive wise. If that card dies you are done. In short we don't _need_ the FusionIO so why would we put out that kind of money for it?

Also we went to 96GB about a year or so ago when we setup those boxes it was a reasonable amount of memory to put in now - we are maxing the thing out at 288GB now.

"I think Xcode is one location where Apple is showing that it does care about developers by building a better product with better integrated tools (git for example ...)."

I guess this is a matter of opinion. Every time I am forced (read: paid) to use Xcode for some project, not only do I dislike the fact that I have to dig out my macbook because Apple's tools don't work on any other platform, but I find actually using them painful. It's been a few months since I've used it so maybe times-are-a-changing.

The last time I used Xcode (4.0.1?), it still basically seemed that it was using the iTunes container. Of course, I have no idea how much actual codebase Xcode shares with iTunes. Apple is probably just trying to be visually consistent between their products here. But I've never been a huge fan of iTunes either. I find the menus and configuration painful.

Though it's apparent that I'm not a huge Apple fan, I'm not trying to troll anyone here. Reading your statement, I saw your praise for their developer tools and it really made me think about the fact that, while a lot of Apple's hardware is competently designed, I'm not really a fan of their software whatsoever.

Off the top of my head, I can't think of a single app they've written (besides mail.app) that I like.

And kudos for them integrating git? Since pretty much every other developer tool includes support for it, I wouldn't say this is all that exceptional.
This is great advice.

This is how the Unreal Engine was architected and it makes it really easy to create new composite objects.

In contrast, when we did the first version of the MyMiniLife/FarmVille engine in flash, in the name of the speed, we made the mistake of not architecting the game object model in this way. We had to go through a painful refactor process 6-months after FarmVille's launch to fix-up the object model because we were duplicating behavior across objects that were really close to being the same...but not at the same time.

Couple other benefits of using this approach:

1/ You can let game designers dynamically create new objects without programmer intervention. Just let them mixup new components as they see fit through an editor.

2/ If you build a visual editor/CMS for your objects, you can do some pretty nifty stuff with custom editors/renderers for components. For example, the UnrealEditor at one point had a custom color picker for the ColorComponent that made it much easier to work with colors than entering R,G,B manually.

3/ If you build in serialization to your components at a low level, you can do things like have lazy deserialization of your components so that they are only instantiated/initialized once you access the component. This may not seem like a big deal at first but when you are working with tens of thousands of objects across millions of users, deserialization time ends up being significant.
I would still use inheritance to create a basic addComponent/componentFunction class. I don't think inheritance is meant to be used for creating as much sub-classes as possible.
But as with all software design, it is important to know where to draw the line. Where have you inherrited all you can?
What you describe is pretty much inheritance vs composition. A tradeoff as old as oop.
OK GO's (Band) programmer?
>for each of those there is a best solution.

This isn't necessarily true. For instance, if A and B are each measurable characteristics of potential solutions and your goal values A and B equally, if all other characteristics of solutions X and Y are equal, but X={A:2, B:7, ...} and Y={A:7, B:2, ...}, then X and Y are equally "good" solutions according to your goal.
This is very cool. Great job! I wonder how cpu intensive it'd be to generate a simple bounce animation.
Precisely. I get a chuckle every time I hear "there's a shortage of developers!"

I want to make a t-shirt with that on the front, and "PAY UP CHEAP ASS!" on the back.

Ask HN: Should I work at a startup?
Throwaway acct...

I'm a well-rounded developer. I'm good with people and I've managed to snag a ton of well-paying work for myself in the freelance world. This is highly convenient for freeing up time to spend with new young family.

And then I get a call about an opportunity to work at this awesome company. They're new, but doing really well. Lots of funding, growth, and revenue. The role suits my skills well. The company's offering is killer, and I could stand to become very rich as they become very rich.

We've really hit it off and I'm meeting again with the company's brass soon. I'm expecting an offer shortly thereafter.

I've never worked at a startup. I'm a little concerned about work hours (40-50 hours sounds less appetizing compared to lazy 25-30 very well paid freelance hours). But the truth is, I'm young (20's) and I don't feel like I've been super intellectually stimulated yet in the workplace. I'm thinking this gig could deliver it, along with other outlined pros.

This all happens on the same day Jeff Atwood chucks the deuce, like "I'm leaving to go hang with my kids more."

With these things in mind:

1. Broadly, should I take it?
2. What specific questions should I ask in order to flesh this out better?
This is cool. I am tired of switching between my browser and terminals.
It still exists, and it's still relevant /if/ you're in the situation Dave above describes - and you have sufficient clout to get stlport included in your code. In almost every other situation where you can actually use the stl, it's probably a better idea to use the libs that come with the compiler.
There does not exist a homogenous entity called "regulation" where more of it is good and less of it is bad. There are plenty of regulations that accomplish no useful purpose, and even more whose benefits are less than the costs they impose upon commerce.

I would hazard to guess that making it harder for small businesses to go public was one of those unintended consequences of regulation that do more harm than good. Sarbox, or at least a portion of it, ought to be repealed.
Cheers Joss! Agreed, that would be nice.. not sure what the best way to format that config would be though.

I don't come from a game development background, but I do find the realm interesting, and I'll probably have my crack at it soon enough.

This post is interesting, it kinda goes against what I think of when I think of OOP. I would have modeled it with inheritance of vehicles, weapons and monsters. But after reading this post I could see how that could be a bad idea.

But I'm curious in what you say. "Hierachy needs to be designed in the space of what you're actually building: renderers, physics, AI and GUIs." Do you care to explain this farther? Why those over the concrete objects? What do you even mean by it?

EDIT: Specifically how what do you mean by having inheritance of physics, renderers, AIs and GUIs?

EDIT II: Grammatical fixes.

The average Yale student has $9k in student loan debt at graduation in 2011. They adopted a no loan policy starting in the 2008-2009 academic year to replace loans with grants.

Harvard, Princeton, Columbia, and University of Pennsylvania have similar policies.

Also, at many of these schools, if you come from a family that has income under around $75-100k (the exact limits depend on the school) they will waive tuition and many fees.

The net result is that, at least for students from middle class and lower backgrounds, if you can get into an Ivy League school (or Stanford, Caltech, or MIT), there's a good chance your family will pay less and you'll end up with less debt than if you went to top tier state school--especially if it is a top state school out of your state.
