Greenwich

I was at a loose end again today so I decided to have an 'anorak day' where I go off and do something self-indulgently geeky. I have never been to the National Maritime Museum in Greenwich so I set off for London late this morning.

I got to Waterloo at lunchtime so I popped across the road to Auberge, a Belgian-style bar/bistro I discovered a couple of months back. After a steak-frites and a glass of Leffe I headed off to Greenwich. 

The Jubilee Line was out of service due to engineering work so I decided to take the boat. The Thames Clippers are a scheduled service rather than a tourist excursion and I got a 1/3rd discount because of my travelcard.   The boat trip from by the London Eye took about 40 minutes and landed me right at Greenwich. 

After a pleasant walk through the grounds of Wren's old Naval College designed for Charles II I got to the museum. I was slightly disappointed with the display, but I'm not sure what I was expecting. The main exhibition space was closed as they were setting up for a new exhibition which opens in a week or so. 

Most of the rest of the collection consisted of  a selection of small boats, maritime art, old naval uniforms and static displays on Liners and London as a port. It was all quite interesting, but not compelling.  The Royal Naval Museum in Portsmouth makes for a better day out, but of course that has the whole of the rest of the Historic Dockyard to entertain you.

I suspect Greenwich's main value is its library and archive which provide an important resource for the serious historian, and there is enough to entertain the casual visitor with the Maritime Museum, the historic buildings in the park and the old Observatory  at the top of the hill.

I visited the Observatory a few years ago and found its display, on astronomy and timekeeping, very interesting;  I'll probably revisit it next time I'm in Greenwich with some time on my hands.

New Toy

I have been thinking of getting a quiet low-power PC to replace my file server at home. After a bit of looking around this system fitted the bill. My system isn't quite the same as the one in the link as they appear to have replaced the Celeron 220 CPU with an Atom during the last few days. I guess it's axiomatic that any PC is obsolete as soon as it ships.

The system is designed to run Windows Home Server but I got a £50 discount for discarding that. The system has two 500GB disk drives and 1GB of RAM so it is an ideal platform to run an OpenSolaris server with everything mirrored across the two disks using ZFS. The basic installation went very smoothly. All I need to do now is make some minor tweaks to the network configuration and set up my ZFS filesystems.

Future plans for the system include setting up an IMAP server, adding SlimServer software to stream music, and getting a GPS receiver so that I can run a stratum 1 clock (NTP timekeeping projects are what allows me to buy new toys at the moment).

Useful software - synctoy

Synctoy is a really useful piece of free software from Microsoft, and I never thought I would use all of those words together in the same sentence. I have a laptop here which I use to manage my photographs, music files, Internet access, lesson plans and materials and anything else which needs a PC.

I also have a Linksys NSLU2 which is a tiny Linux-based NAS/fileserver device which takes two external USB disks and can export their filesystems using SAMBA . The server can be configured to perform nightly backups from one hard disk to the other, giving a poor man's RAID. There is a thriving Linux development community for the NSLU2, which has ported all kinds of Linux software, but so far I just use it as a fileserver.

I run weekly backups from the laptop to a directory on the fileserver using Norton Ghost, but I also needed to mirror my laptop home directory to a directory on the fileserver. This was the first task which led me to look for file synchronisation software.

So far I have been very pleased with synctoy, it has a preview mode which lets me see the difference in content between two directory trees without modifying them. It also lets me synchronise a directory tree from the fileserver to a directly-attached USB disk on the laptop to give me an additional level of backup of irreplacable files such as pictures and lesson materials which I have created.

Fighting identity theft (via unsolicited e-mail)

I was amused by a story in The Register about the fact that the Metropolitan Police's efforts to notify potential victims of identity theft. Apparently some of those notified are treating the mail from the Met as a hoax.
How long before the phishers start copying the Met's mail?
