According to the article, it's an hour (ish) for the initial setup, around 20 minutes to provision new infrastructure (add or remove instances), and around 10 seconds to deploy. The key point being you don't need to add a new server every time you push code.
I've always wanted to take the machine learning class but it looks too fast paced.

Today's Xcode 4 release definitely includes the final iOS 4.3 SDK.
The only button I'm offered in the iOS Dev Center says:

> Xcode 4 and iOS SDK 4.3

https://developer.apple.com/devcenter/ios/index.action
The XCode package you download from the iOS Developer Portal includes the latest iOS SDK, as always. It's not a coincidence that iOS 4.3 and XCode 4 were released on the same day.
I'm fine with proprietary tech, but Adobe Flash and Acrobat are unsafe, buggy and drive my CPU mad.

After reading your comment, I have once again searched for a setting within Chrome to remove the built-in Flash, but I can't find it. That leaves Chromium and Iron.
And then there was Cartagr.am
Since my only iOS project is a single-developer one, I plan on refactoring into Xcode 4, since it lets me rethink how I structure the app. I never did a Universal iOS build of the app that I work on because I got frustrated with making it work in Xcode 3 -- it's worlds easier in 4 (if there is a better word for worlds there, use that one instead. you have no idea how much better).

I simply cannot sing the praises of how much sense Workspaces make, especially when dealing with a Universal iOS app. As a recovering Visual Studio user, they were the feature I was genuinely looking for in Xcode.

You might want to take that approach...Xcode 4 in developer preview seemed to misbehave if I imported a 3.2 project, but that could be because it was developer preview.

That's the time to do from-zero provisioning. It is roughly comparable with the amount of time it takes to get a bare-metal VPS spun up and running, if you have Capistrano tasks which are sufficiently up to date to do it for you. (Upload keys, create accounts, apt-get big nasty list of software, install rails, install all gems and dependencies, set config files, check out code, etc etc.)

(If you are doing toy applications, you can get a Heroku instance spun up in under a minute, but I have never had a non-toy Heroku application work on the first try. There is virtually invariably a gem which works fine locally and then dies hard when you expose it to the Heroku environment. After you've debugged and addressed this, subsequent deploys on Heroku take about as long as subsequent deploys via Capistrano.)

Heroku is a wonderful, wonderful system, but "git push look-ma-no-sysadminning-whee" it is not.
What made launching at SXSW a "do or die" situation? Sure, it's free publicity, but is that worth burnout and product that was rushed out the door?

The ML class has become popular and has been split into different streams. You might try the intro class. Plenty of direction is supplied in that class.
I disagree. There are 400-450 million Firefox users that absolutely will benefit in huge ways from this update. There may have been a time for a while there where some chunk of those users felt like Chrome could offer them more, but that time is gone now.

I'd go a step further and say that now there are going to be an increasing number of Chrome users who will compare to Firefox 4 and want the performance and feature improvements that it has over Chrome and that may hold true for some time.

So, yes, you could look at it that way.
"With respect to the atoms..."

The only sane choice here is for Elixir atoms to be Erlang atoms, in the fullest sense of "to be", so that restriction is coming from Erlang, not Elixir. Erlang does exactly what you say; the memory leak in question is when you blow out that table. The Erlang language and runtime permit dynamic atom construction, which is useful because atoms are also the way functions and modules are referenced and it's nice to be able to dynamically compute such things, but if you continuously generate new atoms, you'll run out of memory.
I am using firefox 4 beta and its almost as fast as chrome plus some extensions I can't live without are not mature enough in chrome for example
pentadactyl + nosquint (hinting doesnt work well with vimium + autozoom), gmail checker (checks multiple gmail accounts), firebug and other development extensions.

You are right, if you are not hooked on some extensions chrome is a good option, my wife is a full time chrome user.

Something else that perplexes me is that even when a window has focus sometimes it still won't scroll. Doesn't matter how many times I click on it. But if I go to the sidebar and jiggle that, it gains the ability to respond to the scroll wheel again. Odd.
It's been decreasing consistently over the last few releases. If we don't find any major flaws in the RC, we'll ship it as final in a week or two. If we do, you can add a few days to that estimate.

When I worked on Akamai's DNS server, I was told that most ISPs cached much more aggressively than we told them to. We would set TTLs at...I want to say 5 seconds...because we were directing traffic based on real-time network conditions; but most ISPs would cache for at least an hour.

Exact numbers may be off, of course; it was a few years ago.

No, I think that the parent post was referring to the transmitters on the radio device. The transmitting and receiving antennas are different, and they place the receiving antenna in a null of the transmitters.

This is easy and practical because they're in a location which is fixed by the PCB/housing. There's no phased array required.
My favorite line in that, after the interviewer asked PG what the big successes for YC were and he answered AirBnB and Dropbox:

I glanced over the rubber docs and it sadly looks like too many ruby projects; big promises, shaky implementation (opinionated in questionable ways), extremely thin documentation.

There are better building blocks if you're going to roll your own EC2 stack (fog and sumo come to mind).

And if you lack the knowledge to roll your own then no, commands like the following are not the answer:

./script/generate vulcanize complete_passenger_mysql

Yes, this may work sometimes and set you up with "something".
But there is insufficient documentation about what this "something" actually is, what the rationale behind it was, and how someone who needs a tool like rubber is supposed to keep it running and in good shape.
It wasn't planned. When we initially sat down to plan the schedule out two months ago, I thought there was enough time to get the iPhone app done. Without that intense of a workload. And then some bugs more serious than I (or any of us) had predicted happened.

FWIW, pretty much the entire time we were in the office working, so was Justin -- asking what he could do to help, if there was anything to test, that needed doing to free up some time, etc. Working that much kind of sucks. But, there are much worse ways to work that hard than with a bunch of smart people who are working just as hard as you are.

No one really knows if there's a bubble before it bursts. They are easier to see in hindsight.

On the one hand everyone in the world is getting a smartphone since the pricing for chips has come down so much this year. That will make the market for mobile computing/commerce/you-name-it huge.

On the other hand, Facebook hasn't really nailed their business model. Yes, it's pulling in a lot of cash, but not enough to justify its valuation. Assume Facebook IPOs in 2012 and because everyone except newborns is on the network, the price gets bid sky-high, but they fail to grow revenue. Investors get scared and pull out and take the rest of the tech market with it. Then Facebook grows credits to the be the biggest payment platform in the world and the whole market goes up again.

Like PG said, market valuations are a sine wave. They are educated guesses, no one knows anything for sure.

No, cue the you're assuming you won't get Xcode 4 with Lion rabble. Seriously. Don't jump to conclusions yet.

Can you clarify the $5-hurts-FOSS argument? I don't mean to sound crass, but there are people who pay more than $5 for coffee. If a one-time charge of $5 to build OS X versions of your FOSS project is a, as you say, "[sizable] obstacle" to entering FOSS development, that's a genuine surprise to me. Especially since Xcode 3 is still absolutely free. If I were a committer on your project I'd buy it myself and donate it, for crying out loud.

They anticipated this, undoubtedly, and put the button right there: "Looking for Xcode 3 because $5 is too much? Here it is!" You're really only paying for the improved GUI. Does your FOSS project use Xcode as its primary development platform, or is it just using the compiler toolchain?

This revolt to $5 is absolutely stunning. Even more worth thinking about is that all the commenting about it on HN equates to far more than $5 in billable time...how many copies could the revolting have purchased?
It's just better business to make the price $0. $5 doesn't seem expensive. It just seems... odd.
I am actually rather shocked that people are being charged extra for DNS - surely the answer is to get any sort of cheap VPS and put DNS on that box? Then again, why are you depending for all aspects of your site's working at all, on a service which costs $2/month?

Even a 128MB RAM VPS could comfortably handle a huge number of requests.

That is an interesting question. However, just because OS X is certified Unix, doesn't mean that the stripped down version of it is also Unix.

To be honest, I'm not sure what value Apple got out of certifying.

Ditto. And I stuck with Chrome until Xmarks started giving me grief. Upgraded to the FF beta about three months ago, and really liked the improvement over 3.6. Even when the Xmarks / Chrome thing sorted itself out, I found that wasn't reason enough to go back. I've also started using a privacy plug-in called Cocoon (also in beta) that I'm really pleased with. Currently, it's FF only.

One other thing. It's small, and non technical, but I find I really like the very compact implementation of the pin tab feature. The way FF adds subtle indicators when the content on a pinned page updates is especially nice.

The upvote has two uses:

1) interesting comment that contributes to discussion with which I may or may not agree with.

2) I agree.

The first use case is preferable to the second one. If you happen to agree with a comment that isn't interesting nor contributes anything to the discussion, then maybe your agreement with it is irrelevant as well.

Extensions. Firefox has the greatest browser extension ecosystem bar-none. In the past, you had to choose between Chrome's performance, and Firefox 3's extensions.

Certainly Firefox was playing catch-up in performance, but we're there now. Chrome is still far far behind in terms of extensions, and showing no sign of catching up.
The thing I'd really like to see in a portable computer is a touch-interface/mouse-interface hybrid. For example, you dock your iPad in a keyboard docking station (with mouse), and the interface morphs into standard OSX, with all the power and abilities that come along with that. Take it out of the keyboard dock, and it's an iPad again, with the finger friendly iOS touch interface (and limited to touch apps). Desktop apps and touch apps could share data, but would ideally have different interfaces. E.g. OSX's Mail.app and iOS's Mail app.

For HP of course, substitute webOS "slate" for iPad and custom desktop Linux distribution for OSX (I wish).

College freshman with an idea. How should I spend my summer?
I'm a freshman at MIT majoring in computer science. I have a startup idea that I'm really excited about, but don't think I have the technical expertise to build it.

I have about 1.5 years of programming experience, and enough web development under my belt that I could build a sloppy but working prototype.

My question: this summer, should I jump right into building my idea? Or should I do other things to raise my programming IQ (internship/side projects/reading/your suggestions) until I feel more technically confident?
I haven't seen this in the comments yet (might have missed it), but I had always assumed that I was ALREADY paying for Xcode w/ my $99 developer connection fee. $5 is a small amount, for sure, but just seems like yet another way that are trying to squeeze me.
The point is not how to solve one particular restriction, but that every IT department has bizarre and stupid restrictions. And that, over time, all these papercuts to the soul will take their toll.

Full disclosure: I'm one of the rubber devs.

But, did you look at any of the wiki pages? I think all of your questions are answered right there:

https://github.com/wr0ngway/rubber/wiki

I think you largely missed the point of rubber. Rubber could use something like fog (and indeed, we plan to), but it's not a fog competitor. It allows you to do role-based deployment with capistrano.

At the core of it, you have a set of roles (e.g., app, db, redis, web, resque_worker) and a set of machines belonging to those roles. You have role-based config and you can interact with subsets of your cluster through those roles.

heroku is good at what it does. But there is simply no way I could have built Mogotest on it. And most of the rubber projects I've come across would never work on heroku.
The creator states:

This works in Audacity, and probably any other audio program that can import raw PCM data. I imported it﻿ as 22050hz 8-bit stereo audio in Adobe Audition, but it seemed to sound mostly the same in Audacity.
All I did to the audio was master it slightly to make it sound less harsh to the ears, as well as remove a long section of noise.

Did you import it with a 22050hz sample rate?

>I've always considered Xcode to be the nicest IDE to use in terms of user interface, though it wasn't exactly pretty. It's just the competition was so ugly and cluttered. I've often likened saying Xcode 3 was the prettiest IDE to saying that it was the nicest smelling dog crap. Xcode 4 however, genuinely is pretty. I love looking at it and admiring the amount of work that has gone into it. Apple has had some of the prettiest developer tools in terms of Interface Builder, Instruments, Quartz Composer etc for quite a while, but Xcode was dated. It now feels like the sort of user interface you'd expect from Apple.

Looking at the screenshots, I don't see how it's prettier than, say Visual Studio 2010. Maybe it's subjective?

There's a lot of competition in this space from some pretty big, well established players.

I'm wondering what you're bringing that isn't available yet? What's your differentiation?

The issue you're going to face (because you're a small team) is that you won't be able to reach feature parity with your competitors. I'd suggest to focus on one aspect of your product first, execute it perfectly, and then possibly expand.

Also, does your product actually serve a need? Unless it has all the features of MailChimp, Socialblaze, Wordpress, etc... I would rather just use all of these products independently. Otherwise, you'd still end up using them for certain things.
Even though there is a lot more to Reddit than Hacker News it is still interesting to see the difference.

Part of the memory increase was caused by the new JIT. There has indeed been work done recently to bring memory back down. You can see a list of fixed and still-open bugs here:

For example, this bug significantly reduced memory usage, and was fixed less than a month ago:

However, there are many memory vs. speed trade-offs in software, and as memory continues to get cheaper, you'll likely see all browsers choosing to use more memory in order to run faster.
