Looks like the graph is rendering a different expression than the one you are modifying. If you tap to select the graph element view there’s a graph config button you can tap to select which expressions are actually active for that view.
Microsoft won't even let you move your X-Box Live account to a different country/region. My wife has this problem now since her Live account is stuck in Europe and there's just no way to move it to the US. This is extra troublesome on the X-Box since some games are region locked so she has to order some games from Europe.
I think there may have been some misunderstanding here regarding his App store account though; I also see a comment on his blog indicating this. I moved from Europe to the US and can't remember having any problems moving my account to the US. I can imagine that it's problematic to have two accounts on the same device though.
It's basically a UI problem: while you can authorize content from multiple regions, updates and subscriptions require actually being logged in to the iTunes Store, and you can't log in to multiple regional iTunes Stores at the same time.
I suspect one of the reasons Apple hasn't "fixed" this is because doing so would require renegotiation with content providers, who'd most likely push for even more customer-hostile restrictions.
Packrat parsing has fairly horrible memory usage. LPEG is amazingly frugal in terms of code size, run time, and memory usage.
It's worth noting that the PEG ordered choice operator leads to much more restricted backtracking than occurs in most regex implementations, so LPEG has much more predictable performance. And unlike a DFA matched you still get straightforward capture handling.
I'd love for Amazon to remove the DRM from their books, and just sell books in epub format which can be read on any device without a Kindle app. That would solve Amazon's problem with iOS/Apple, and also be an ideal solution for end users. EDIT: what I mean is, music is now sold without DRM. Why do we still need DRM for ebooks? I'd love to be able to just put all my ebooks in a Dropbox folder, and not depend on Amazon to create an app for every platform where I want to read my books.
But if you'd like Amazon to make a concession as large as this, surely Apple should be asked to make a few concessions too?
Both companies sell IP - and both rely on a various forms of DRM to enforce scarcity. I think selling IP will eventually be seen as a fruitless (and unsustainable) pursuit - but for the time being this is a way both these companies are making a profit selling digital goods.
As far as I can remember, Apple/Steve Jobs talked the music industry into dropping DRM on music. As the leading ebooks store Amazon should be the one to push to remove DRM from books.
Well, I'm still waiting for the day when I can drag and drop one of these DRM free MP3s onto an iPod (without having to shackle my device to my computer via iTunes).
It's not exactly freedom in the best sense of the word ;)
The Dropbox app on iOS can play mp3 files so you don't have to use iTunes to sync your music.
iBooks having DRM is (IMO) a problem with the publishing industry, just as DRM on music used to be a problem with the music industry. I want Amazon, and Apple, to push the publishing industry into dropping DRM on books.
I think I'd like to be able to pay an author directly - that would be my ideal solution; and an ebook should necessarily cost less than a paper book. But I agree - removal of DRM should be a target.
You can do this yourself (you can Google for how-to). The process of stripping Kindle DRM-MOBI format and converting it into ePUB is about as simple as ripping a DVD.
GLM (http://glm.g-truc.net/) - A C++ mathematics library based on GLSL. It's not a new library, but I didn't know about until 2010. It's really convenient to use (almost) the same syntax in C++ as you do in GLSL.
Actually, Lua's table object is split into two parts. The array part, which is accessed using numerical indices, and the dictionary. It's done like that to enable fast array access, and I do find it an incredible useful feature in Lua.
In my experience 1-based indexing is not a problem when you're just writing Lua code. I've sometimes been frustrated when creating Lua bindings to C-modules which involved some kind of array access though.
I couldn't agree more. I've been a Spotify premium user from day one (I loathe commercials), and it's absolutely worth the monthly fee. As a premium user you also get the iOS/Android app, which lets you cache up to 3333 tracks on your mobile device for offline playing.
A personal hero for me as well. In addition to the projects listed in the wikipedia article, I'd like to mention TinyGL (http://bellard.org/TinyGL/), which was really useful for OpenGL on BeOS/BeBox (much faster than Mesa), and qemacs (http://bellard.org/qemacs/) for editing really large text files.
