Platform 3 Chelmsford closed
Platform 3 Chelmsford (Viaduct Road) is closed, gone, shut down... for good it seems.
I visited last month to redeem a lunch time voucher to find it was only opening in the evening. Now the window of the shop shows a letter stating that the premises have been entered by National Rail. Has this company gone bust as well?

Large file synchronization
Efficiently synchronize copies of a large sparse file locally. I deal with a large amount of large sparse files because of virtualization and other technologies. Because of their size, often a small number of blocks have data and, of these, a small number of blocks are changed and need to be backed up. Using a log-based (snapshotting) file system on USB 2 as a backup device, I only want to write blocks if absolutely necessary.
So what's the solution? Some simple custom code that
- checks that both file sizes are identical;
- verifies that some metadata has changed (i.e time stamp, permissions or owner/group);
- reads both files block-by-block;
- writes only changed blocks to the destination file, and
- updates any changed metadata.
