cesare··on Apple removes Scratch from iPad/iPhone/iTouch
"No, it's because (as far as I can tell) the Scratch iPhone app was acting as a Scratch interpreter which is explicitly not allowed on the App Store to begin with."

Which goes to show, once again, that this policy is really stupid and that it doesn't affect exclusively developers, but also the educational potential so vehemently touted by all the iPad/iPhone/iTouch fans.

cesare··on Apple removes Scratch from iPad/iPhone/iTouch
IMHO, this should cause more outrage than all the developer related policies.

Apple has always been a world apart, with a strong philosophy and its own priorities. But the culture around its products was all about fostering creativity.

I used to say to friends: get a Mac if you want an hassle-free computer to make things (music, graphics design and even programming. Does anyone remember HyperCard, which at one point was bundled with every mac?).

The argument that the iPad/iPhone/iPodTouch is not a computer is really myopic. It's the culture that has changed.

cesare··on Pharo Open Source Smalltalk Release 1.0
I've made some projects with Squeak in the past.

This Pharo image seems really clean. And the tutorial is a very nice addition.

My only disappointment with Squeak is that all the multimedia related stuff was really outdated and the performance was poor.

I've been subscribed to the mailing list for a while and it seemed to me that very few people were concerned with this. All the development was focused on developer tools.

There was a guy (couldn't remember his name/website) who was working on really interesting graphical stuff. He was rewriting the Morphic gui from scratch. I hope his work will be eventually merged with Pharo. EDIT: found it: http://www.jvuletich.org/Morphic3/Index.html

With strong and updated multimedia capabilities this could become a modern HyperCard.

cesare··on No, We're Not the stupid ones
"It is okay to expect people to invest a little time to learn how stuff works and to retain an adequate portion of that education."

Amen.

cesare··on The App Store: Quality control without the quality
It seems a pretty rational argument to me.

I have no idea why you're being downvoted.

cesare··on Computers shouldn't make people feel like idiots
Sure. They should take it for granted. </sarcasm>
cesare··on Alan Kay (1972). A Personal Computer for Children of All Ages
"right" in the same sense that it's a good idea to teach math at school even if only a very limited few will become mathematicians.
cesare··on Alan Kay (1972). A Personal Computer for Children of All Ages
The exact opposite of the iPad. Or, better, how the iPad could have been if the computer revolution would've gone right.

> I got an app rejected because the reviewer did not like the price I set.

That's a new one. At least for me.

Great advice. Otherwise, you might learn something. By doing. Which is so passé.

Why is this site called 'Hacker News' anyway?

cesare··on SICP in Clojure (In Progress)
The website runs on Drupal, which has multi user editing, revisions etc. The 'book' module (included in the default installation) is basically a wiki. So, the infrastructure is already in place.
cesare··on New iPhone app piracy over week one.
> These apps are distributed binary, yes?

Like OS X apps, iPhone apps are distributed as bundles (directories) containing all the required files (http://en.wikipedia.org/wiki/Application_Bundle).

The info.plist file is a plain xml of key/value pairs of properties that tell the OS how to handle the app, which kind of files can be opened with it etc.

AFAIK, the application that kids use to crack iPhone apps adds a key/value pair to the info.plist which is needed to load the app on a jailbroken device. So, you just need to check for its presence. If the key is there, the app has been cracked.

cesare··on New iPhone app piracy over week one.
IIRC, some apps just check the integrity of the info.plist file (which needs to be modified for the crack to work).

> I wonder if this project could use JOGL bindings...

It wouldn't make much sense. Opengl is for realtime 3d graphics. Here you just output the final rendered image, which is a bitmap.

cesare··on Matt Cutts 30 day challenge for October: No Microsoft Software
A more eye-opening challenge would be: no free-open source software for a month, no services using open source software (no sites running on an open source OS or server etc.) and no operating systems which are even partly open source (so no OSX either).

Another less radical but still quite interesting variant would allow using open source licensed software (BSD, Apache etc.) but no free software (GPL, LGPL etc.).

cesare··on Building iPhone Apps with HTML, CSS, and JavaScript
Have you read at least the titles of the chapters of the book?

Or the official Apple documentation (http://developer.apple.com/safari/)?

Edit: where in the book did you see how to use geolocation, vibration or any other feature which is not available with a web app developed for mobilesafari?
