FYI I've been going thru 2 Racket tutorials (http://docs.racket-lang.org/continue/index.html and http://docs.racket-lang.org/more/index.html). Very informative, and they run fine on my laptop. (OSX Intel 10.6.7 Racket 5.1)
In addition, I am trying to run them on Amazon EC2 with some challenges (doing it with Jauny AMI and Racket textual build 5.1 for Jaunty.). Most of the tutorials work fine except 2 places: 1. Following along the system (aka '/more') tutorial: When evaluating (require readline), REPL sometimes hangs but not all the time. 2. Following along the blog webapp: When running model-3.rkt (sqlite3) fails due to missing something. (libsqlite.so ?) [I realize there is v5 now but this was done with sqlite v4 from PLanet per tutorial. Lots of warnings and complaints during require phase, it seems.] I can run sqlite3 by itself fine. It can read and dump some test sql via shell. JUST TO BE CLEAR, I don't expect anyone to go out of their way to fix the above, JUST TO BE CLEAR. Lots of other things can be blamed, I understand. Network, EC2 particulars, Jaunty AMI, etc. Question is: Has anybody done this on EC2 or other 'cloud' platform? If so, I would love to hear/read about pitfalls. Also, if you know running Racket on Xen or other virtual setup is not advisable, please let me know before I spend too much time/effort. 3. One more. This observation regards Dr Racket. Sometimes I cannot type [ or ]. It becomes ( or ). First I thought my machine was acting up. But I noticed that I can type 'cond([' fine. So I am thinking its the Dr who is 'helping me too much'. If so, Dr should consider that '[' appears in other places beside 'cond(['. Question: Am I the only one experiencing this issue with '['? Sorry to bring down the intelligence level of this mailing list with my questions about 'immediate utility'. My apologies. Cheers, jGc PS: I am keeping a note here (http://pixbyfunc.appspot.com/pub/racketoncloud/first.html). It's not quite done yet but you can look at the issues surrounding sqlite3 in case you want to duplicate. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
