The fact that you know the shortcuts for select all, copy, and paste puts you in the top percentile of users. Most people don't even know that's possible, and certainly not with keyboard shortcuts. (The point being that for most users the f

It seems I misunderstood inline caching. If the call site itself is modified then it can be as fast as the JIT compiler. Interesting.

I didn't mean to imply that messages are faster than JIT compiled calls. There's still at least one level of indirection in the optimal case, not sure about in practice. However Dalvik being faster today doesn't mean that Obj-C is suddenly

This guy should know better being an iPhone developer. > but it also has the property that method calls in Objective-C are very slow and the more code that you write in Objective-C instead of in C/C++ the slower your codebase becomes. O

This is so true. I like me some Linux, but OS X has won me over. I thought the iPod was a fad for people with money to waste, until I got a Mac and discovered how much thought Apple puts into their products. Sure I had a HDD based MP3 playe

They should be. I like Ruby, Python, and C but you can't help but be jealous of more robust platforms such as Erlang. We'd do well to stop inventing more of the same crap and actually advancing the state of the art. C isn't going anywhere n

Now all he needs is a velcro glove to hold the iPad comfortably with one hand.

This will be possible when the new annotations API is live.

Ah yes that's true. You can use Protocol Buffers but still over HTTP. You'd have to use Erlang to get around HTTP, which obviously won't work for everyone.

Awesome. If functions are allowed as data, evaluated as they're encountered, this has great potential.

Have a look at Riak. It scales up (and down) very well. And it's been in production use for a while now.

Not sure if kd-trees are lesser known, but they are neat. I only learned about them recently so to me they were "lesser known". "In computer science, a kd-tree (short for k-dimensional tree) is a space-partitioning data structure for organi

I must not understand monads. I thought I knew the basics of how to use them, and have used them in the little bit of Haskell I have written, but that makes no sense at all to me. What are the apples and oranges supposed to represent? Why w

Marco is right on as usual. My use of the iPad is similar anyway. While you might be better off with a MacBook Air if you find yourself using iPad + keyboard a lot, it's still about $1000 cheaper to get the iPad.

There are open-source libraries (mostly MIT and BSD licensed) for all the key things you need: cookies, sessions, serving static files, talking to DBs, templates, etc. I pieced together a web service using node-machine[1] at the core (port

You could do it with a plain old text editor afaics. It looks like a regular Cappuccino project. (edit: that is, if you only want to deploy it for the web. I don't know about building a desktop version) Btw it does support labels, they're j

I can submit a link to any URL in my control and swap it out for something else later. That can apply to every single link on the web. By that logic they should maintain a whitelist of not only redirection services such as shorteners, but f

The parts that are written in C are mainly the lisp interpreter itself, and some windowing stuff. Unless you are doing something really strange you never need to dive into the C internals.

I love js2-mode and only use espresso-mode for JSON. Do you know of any comparison of the two modes I could read to get more info on this?

You can also put (server-start) in your .emacs config.

You can bring up Emacs' buffer list sorted with the most recently used at the top (bs-show). This is equivalent to alt-tab in the worst case. Because I can search this list (it's a standard Emacs buffer), I can get to anywhere in the end or

There are operations where the mouse is more efficient than the keyboard and vice versa. Anyone who says otherwise is selling something. That said, I often trade the time + context switch of moving to the mouse for a slightly less-efficient

That is technically true, but no one would actually be productive in that environment. Switching to the file you want is an O(n) operation with that workflow. That would drive anyone insane. In proper editors you can switch to the file you

Wow. I was using CarbonEmacs 22.3 till now, so I'm not sure if it's the switch from CarbonEmacs or just v23, but startup is about 1-2 seconds now instead of 5-10 (2ghz Core Duo "Yonah"). Either way, I'm sold!

So, Emacs can be any or all of 4 things depending on your point of view. 1) lisp interpreter 2) text editor library written in lisp 3) a very flexible text editor 4) whatever you want to make it Because it's a general purpose programming la

What I see is you ignoring a significant chunk of the market, and entering a market with more competition, and more fierce competition to boot, from bigger dev houses. If anything it makes more sense to go for Mac + Linux instead of Windows
