From hearing the details it seems that there is no real limitation to what you can execute as long as it runs on the instance. I get the feeling that if you zipped up all of the parts of python or ruby you need to ru you could execute a script using either of them as long as you initiated it from your node script. The key word here is probably "support" and that may be more of an issue if you want to edit your scripts with their web IDE.

It is also worth pointing out that you can fly to DC and NYC in under 2 hours from Louisville. You can fly to Chicago and get there before you took off thanks to the time change. So you have access to pretty much any of the "best" of those things listed here in about 3 hours including the time it takes you to drive to the airport, get through security and board.

I will second this. At the bottom of this article there is a reference the article I wrote a while ago when Amazon released this feature. I was planing on doing multipart uploading at that time using the FileReader but there was a bug in the way S3 did CORS so I didn't want to continue until that was fixed. They fixed it and I never came back to it. Maybe be a good time to try it again. Resuming a partial upload seemed like a good win to me.

This is great but sadly you can't resize images in the same version of mobile safari so it limits the usefulness for image uploads. There is a bug that makes large images incorrectly render to a canvas. It seems odd that this wasn't a use case they tested against.

There are probably any number of reasons, valid or not. The easiest to cite is "Who do I call if we have a problem with OpenJDK?"

Outside of OpenJDK there are other issues that make this a hard push for Enterprise customers. I haven't seen a large installation that uses memcached. Most go with something that is tailored for Java like Terracotta's bigmemory. Again it is "Who do we call if it breaks?"

Heroku is in an interesting place here I think. They are certainly on the right trail but this is VMWare's back yard now. Being a polyglot platform is probably a disadvantage for Heroku in this arena. If you look at VMWare they have a complete system tailored to work with Java. The hardest hurdle I see is that VMWare's solution can go from developer size deployments to production all on the hardware owned by the Enterprise. Heroku can't do that and I assume will never do that. Not "owning" the entire system will be an uphill battle for a lot of Enterprise customers.

Sadly I think the OpenJDK will scare off most "Enterprise" developers. I see this as a good option for testing/development but I have never seen an Enterprise use OpenJDK in production. Most are using Oracle's JDK or some other special purpose JDK. And if you can't make it look exactly like production most shops are not going to touch it.

Apple really needs to stop putting this type of stuff under NDA. I've had something like this since 3 weeks after WWDC but I was sitting on it waiting for the NDA to lift. So many people are ignoring the NDA that at this point it seems that maybe Apple is effectively not enforcing it.

I found this interesting when I saw it before. I had thought of something similar after seeing Nimbus Chameleon http://blog.jeffverkoeyen.com/nimbus-chameleon The difference for me however was I was just thinking iOS and was wondering if something could be created that utilized the UIAppearance APIs in UIKit http://developer.apple.com/library/ios/#documentation/uikit/...

Edit: I realized I ran into something that does almost exactly what I wanted a couple weeks ago on github https://github.com/robertwijas/UISS

I just picked a line out of the area to point to. I'll pose a few questions that go into more about why I believe this is code that isn't straightforward and in general a bad reference point for a beginner:

* Can you tell me why that entire block of code gets dispatched to one queue then right into the main queue?

* Can you tell me what queue the animation completion blocks run on and why it might matter?

* Can you tell me what queue the network request runs on?

* Do you think the animation completes before the network request finishes? Can you tell me why/why not?

* What happens if the network request fails?

I think the idea that Apple can't require MAS is wrong. Maybe they can't for everyone but I would bet they can for a lot of people and probably plan to. At some point developers will be buying the developer version of the OS that gets them around the sandbox.

It should stop that type of piracy for IAP for the most part. From what I have seen those hacks just fake receipts that will not pass this type of validation. What could happen at some point is jailbreak hacks using real receipts that do pass validation. For that to happen someone would have to make a real purchase and then give that receipt out. That makes it traceable back to the original receipt purchase and adds an initial hurdle. If this were to become popular it would be easy enough to just catalog the hacked receipts and reject them. Apple could do that or it could be something that gets integrated into the system before the request even goes to Apple. This type of server side validation is a pretty solid defense against piracy.

The videos for sessions 205 and 219 would probably be the first two I would recommend if you are an iOS developer.

The videos for sessions 600 and 601 would be good if you are developing web apps.

You are just counting EC2 cost. The AWS cost for 410TB of S3 storage is around $39k. You would need to add in BW cost on top of that.

It is also interesting that they seem to be using Akamai for a CDN instead of Cloudfront so not a completely AWS based solution.

I wish they went into what they are storing in S3. 410TB is a lot of storage. My initial guess was cached images but 80M objects breaks down to 5MB per object and that is a lot more than what is needed for image caching.
