This is a reverse polish notation (ie stack-based) calculator program written in ANSI C. It uses a dynamically allocated stack, so it can hold any amount of data in the stack up to the memory limits of the computer you are running on. It is currently using double-precision floating point operations although I might write a version using GMP (GNU multi-precision library) instead which will be much more accurate.

This site is now on slicehost! Got a slice yesterday and have been setting it up. Will use it for all my sites from now on, unlimited configurability and its wicked fast even though i’ve only got the 256mb slice at the moment.

Well I setup a new server that’s running at home a few days ago, and i have moved this site to it which will result in it actually being up most of the time.
I’ve also used zoneedit, which is really cool, to point www.shadowservices.biz to the server.
Holidays right now, back to school in a few weeks. Looking forward to it actually, just drifting and playing games atm…
P.S: Server is a Celeron 2.4ghz, 256mb ram. The ram is constraining really but the processor is nice and fast for a web server…

But I can’t be bothered writing anything about it yet, still setting it up.
Blah.
P.S: Linux drivers awsome, apart from the NIC but got the drivers working for it now – They’re not in the kernel yet.

Wednesday: Drive down from Auckland to North Egmont, Stayed at the Camphouse.
Thursday: VERY wet, lots of ice and snow blowing around and mostly into us. Walked from North Egmont to Holly Hut. (3 hrs), but they were a interesting 3 hours! Could’nt see any views though.
Friday: Planned to get going in the morning, but little bits of cloud whistling around the hut at insane speeds – The whole hut would shake. Managed to do the 2 hour walk through the swamp and along some ridges in a break in the weather though, to Pouakai hut. Wind shooting around the hut with serious hail coming down the windows, so we cowered there for the rest of the day.
Saturday: STILL Blowing, so we changed our plans from the track completing the Pouakai Circuit back to North Egmont to taking the Mangorei track straight down and got a ride to north egmont to pick up our car and get changed into some dry(!) clothes, and drive back up to Auckland.
Did’nt get much walking done and spent ages in the huts barely able to go outside, but Thursday we did get frozen which always helps.

Should get my computer and my new Genius Ergo 525 2000dpi gaming mouse on Monday!
