Re: Mono 3.2.7 with hard float

*shameless plug* I managed to build this on a clean raspbian install, but there were a couple of gaps in the install instructions, so I wrote my findings here - http://neildanson.wordpress.com/2013/12/10/building-mono-on-a-raspberry-pi-hard-float/ Hopefully of use to someone (at least until it gets ...

Re: Raytracer in C# & F# running on Mono

Exciting news: F# version - under 5 minutes. That's over twice as fast on Raspbian! The C# version was around the 7 minute mark - so around 33% faster. Bad news still tho - bitmaps seem totally broken. The saved output is garbage for both versions. Identical garbage but garbage nonetheless. Identica...

Re: Raytracer in C# & F# running on Mono

Good news: **significantly** faster Bad news: don't know by how much yet So if you look on the 1st screenshot you'll seein the top left corner there are some numbers. That's the render time. It worked on Debian Wheezy. On Raspbian it gets to the rendering text on the Graphics object and barfs. So to...

Re: Raytracer in C# & F# running on Mono

I've installed Raspbian but not mono yet. I'll probably test in next couple of days - Daddy duties come first :)

Will post results here, but feel free to get code and try first :)

Re: Raytracer in C# & F# running on Mono

(redface) now the repo is public for anyone to clone.

Will be interested to see if hf enabled raspbian makes a significant difference on Mono as its almost all fp math!

Re: Raytracer in C# & F# running on Mono

"On my i7 at work it renders the 1280x720 scene in around a second. On my raspberry pi it renders in around 11 minutes " So around 600 times slower than an i7 on .net vs pi on Mono) Its almost all FP math so i'm guessing that Mono on debian on the pi is using soft fp? That would explain why it is qu...

Raytracer in C# & F# running on Mono

https://bitbucket.org/thedo666/raytracer I decided to port some old code a while back to F#. I then decided to tidy it a little and run it on my Raspberry Pi. I've attempted to make each version as idiomatic to the general language syntax as possible, so there are differences (although the scene ren...

Re: Options for languages to use on the Pi

I'll try it again and report back the full error. It was a 100% fresh debian squeeze image on an 8GB SD card.

IIRC it was complaining that it was out of disk space, but I'll double check tonight.

Re: Options for languages to use on the Pi

So suggestion wise Haskell seems to come pretty high. I've had a tiny bit of exposure to Haskell from colleagues at work, but am largely in the dark. Definitely worth a look for me. Maybe I'll finally understand type classes and monads (and why their more powerful in Haskell than computation express...

Options for languages to use on the Pi

By day I'm a professional C#/F# developer, and an ex Pascal/C/C++ dev. I've got my Pi set up and I'm thinking it might be fun to learn a new language - here are some options I'm thinking of....... 1: Erlang - seems like a perfect fit for the Pi in many ways. Given the scalability factor of Erlang, a...

Re: Programming with *insert language here*?

By day I'm a C#/F# dev, but many many moons ago I used to do lots of C++ and ASM. So I'm hoping to go back to basics and learn ARM ASM and relearn as many C++ tricks as I can without incurring the hit of relearning the internals Win32 to do anything remotely interesting.......

Re: Portable screens that dont cost an arm and a leg

<t>I've been watching the Raspberry Pi story unfold with great interest and like many people intend to buy one to try to help bring back some fun to my coding time. I've been looking into purchasing a small 5-10" screen that I can use on the device, so I can keep it all-in-one where appropriate and ...
