I just don’t know what to spend my 2p coupon on!

I love Amazon’s AutoRip feature. For just a few quid extra you get a real physical product and the convenience of downloading MP3s right now.
Recently though I’ve noticed cases where Amazon wants you to pay more to not receive the CD in the post. E.g. I came across these two in the last few minutes. Not that I’m complaining, mind.

I was searching the map for somewhere to explore this weekend when I came across, in an area I hadn’t previously visited, a landmark grandiosely called the “Temple of the Four Winds” which sounded like the perfect place for an adventure. So like a hero in a trashy fantasy story I set off on my quest.
The first notable thing I came across was this Buddhist (or perhaps Hindu?) shrine just off a path in the woods near High Wycombe. As it happens, this was way more interesting than the aforementioned temple, but more on that in a minute.
Oh yes, the Temple of the Four Winds. With the name like that it better be a huge awe inspiring structure. Here it is:
Not quite what I was expecting. (Although someone on Flickr has a much better photo.) Turns out it’s not even the “proper” Temple of the Four Winds which is apparently at Castle Howard. And you can’t even get close to it, in the winter at least, as it’s inside someone’s estate. I’ve no idea why the Ordnance Survey deemed it significant enough to put on a map.
A little disappointed I spied a much better destination nearby, West Wycombe hill. It’s very steep and once you get to the top there are fantastic views over High Wycombe and the Chiltern hills. There’s also this mausoleum structure which you can see from miles around:
After that I headed back to Marlow via Lane End conveniently arriving at the train station just before sunset. Alarmingly I was only a few miles away from the site of a vast chasm that opened in the earth this afternoon.
Some more photos I took on my travels:

I was recently alarmed to discover that my tea making regime is not ISO 3103 compliant. I have amended my practices and suggest you do also lest a surprise inspection visit from ISO Technical Committee 34 (Food products), Sub-Committee 8 (Tea) finds you non-compliant.

Went for a walk in the Chilterns today: out to this pleasant place with a duck pond called Russell’s Water. It is so muddy outside at the moment. Progress was significantly slowed trying to avoid bogs. Took a photo of one of the less muddy areas with some pleasant winter woodland:
Just as I was getting back to Henley I fell victim to the freak storm that travelled across the country this afternoon (it even made the news on Radio 4!). I got very very very wet. But at least it cleaned my boots.
Thought I’d try to get back into the habit of mapping my adventures for future reference, so here’s where I explored today:

Went adventuring in the Greenwich region a few weeks ago with acquaintance Blodgett. The highlight of the area is obviously the DLR, here I am at the front of number 83A:
The next exhibit is a sundial with embedded cannon which fires at noon:
At one point it stopped raining and there was a pleasant view from the observatory to the dome:
Itinerant ice cream salesmen are a menace to our society.
The Waterloo and City line is theoretically important as the base case in all inductive reasoning on the underground system.

I went to Rye Harbour with my parents last week on the one day over Christmas that didn’t rain. We visited the same place almost exactly four years ago as documented on this very blog, and I took a very similar set of photos. Reassuringly the red and black house is still intact. Good waves down on the beach this time.

I’ve been dogfooding my VHDL compiler for a project at work and now that it’s gotten to the point where it can simulate non-trivial designs, compile times are becoming significant. Especially when files use Xilinx primitives as the
vcomponents library takes a while to load.
At the moment I’m re-analysing every source file for each change I make, so obviously an improvement would be to write a makefile and only re-analyse the files that have changed and those that depend on them (e.g. an architecture must be re-analysed if the corresponding entity changed). But figuring out and maintaining the dependencies by hand is tedious and error prone so I’ve written a makefile generator that recursively finds the dependencies for previously analysed or elaborated units in a library. Invoke it like this:
nvc --make my_top_level >Makefile
make will do the minimum amount of work to rebuild all the out of date files. If the argument to
--make is an elaborated design then two convenience targets
wave will be added to run the simulation and run with waveform output respectively.
The code is fairly compact: only 400 or so lines of C.
This also turned out to be handy for solving a long-standing problem of not being able to bootstrap the standard and IEEE libraries with parallel make (
make -j). Previously the dependencies in the automake input file were incomplete, but now these are generated automatically by a
gen-deps target. The output (e.g. here) is then mangled with sed and committed into the git repository (this solves a chicken-and-egg problem where the
gen-deps target can only be run in an already built tree).

After a hiatus of over 20 years I got another Pirate Lego set for Christmas! My parents tracked down from eBay the one set I was missing from the 1989/90 Pirate range, 6270 “Forbidden Island”. Got all the bits and the original instructions! Flag was a bit borked by I replaced it with a spare on I had.
Here it is with the big pirate ship and raft. Probably acquired those on some previous Christmas. Apparently there’s some newfangled “Pirates of the Caribbean” themed pirate Lego: kids these days…
