...nse of running on a "virtual machine"", but isn't the interpreter itself a virtual machine? I'm not looking to emulate any particular processor - just interested in a tool that will help teach how a processor works.   Can LLVM help, or am I completely off track?   Thanks, M.

...there is an MMIX backend for gcc available. Also, although it isn't a virtual machine, the MIPS architecture is relatively simple and regular, and thus has been commonly used educationally as an introduction to machine architecture and code generation.

...th x86 directly. On the other hand, if you are only interested in a teaching tool, why not use something like SPIM for example? If your usage model is different than SPIM then explaining it may clarify how LLVM would fit. http://pages.cs.wisc.edu/~larus/spim.html - Daniel > Thanks, > M.

...o be an assembler that can also execute the code (it does not execute binary files). In addition, I'm probably asking for too much. Ideally, I'm looking for something like MS Visual Studio with that executes on a virtual software machine, whose source code is freely available.   Thanks, M.

Hi there, I can''t upgrade rspec on rails to 0.7.5.1. I followed the install guide on the website without sucsess. Here''s my env info: $ rails -v Rails 1.2.2 $ gem -v 0.9.2 $ spec -v RSpec-0.7.5.1 (r1395) - BDD for Ruby http://rspec.rubyforge.org/ $ spec ... <snip> ############################################################################ Your RSpec on Rails plugin

For those interested .... rake spec:models seems to clone the test database from development. If your dev db is empty, the models task fails mysteriously. Anyway, to make sure your dev db is at the current migration version, I added this dependency in lib/tasks task ''spec:models'' => ''db:migrate'' Now the dev db is migrated up with each test pass.

Hi there, Is it just me or do many other rspec / rpsec_on_rails users spend more time than they would like feeding the framework ? Don''t get me wrong, I love rpsec, but I seem to spend about 2/3 hours per week hunting down rspec problems. For example, today `rake spec:models` is broken. When I migrate, load fixtures and run `spec -cfs` all is well. When I run `rake spec:models`,

...terrupts, timers, DMA controllers, etc.. I know that your interpreter does not, but I thought I might add these peripherals in.   If you have any suggestions I'd appreciate hearing them. I know about the various PC emulators like BOCHS, but they're doing a lot more than I need.   Thanks, M.

I want this to be a function, so I don't want to just manually exclude a,c, and f.

I''d like to use a frameset to separate the content in an app I''m playing with into 3 separate panes. A 1/3 page width left pane will be for general navigation, (so rarely needs reloading). The main content separates into a top and bottom pane, (with the top pane being set by the nav pane, and the bottom pane being set by the top pane). Unfortunately, I''m new to

Hi there, I have a *really* weird issue with rspec on rails: Given a time meridian formatted using %p When I run `rake spec` the time meridian is converted to lower case: expected: "Today 08:00 PM", got: "Today 08:00 pm" Yet when I run `rake spec:models` and `spec -cfs app/models` the specs pass, ie the the time meridian is in upper case. Anyone got any ideas how I

Hello, On my previous TFTP server I had logging. I did see all requests in logfiles. On my current TFTP server I have also added the options '-v -v -v', but nog logging. At least I can't find it them in /var/log/*/* Where does tftpd-hpa writes it's logging? Groeten Geert Stappers -- Leven en laten leven

Hi there, I installed the rspec on rails plugin for a new project today and guess what -- it blows up! All by other rspec on rails projects are working fine. I updated all gems & still no joy. Any ideas how I can troubleshoot this one ? Here''s my setup: - ruby 1.8.4 (2005-12-24) [powerpc-darwin8.7.0] - Rails 1.2.5 Installed with svn: ruby script/plugin install
