Via MJ whose blog I discovered by a referer entry in my logs I notice that IOL has RSS Feeds for their news, this is excellent news since I always liked their news but could never be bothered using an actual browser to read their site regularly.
I have been spending a lot of time looking at network dumps of SMPP traffic to assist in debugging some network issues. I was a bit rusty on some of the finer details of all the various TCP packet headers and my reference was at home. Google found an amazing resource on firewall.cx titled Anylising the TCP header.
The document spans 7 sections covering the following:
Section 1: Source & Destination Port Number
Section 2: Sequence & Acknowledgement Numbers
Section 3: Header Length
Section 4: TCP Flag Options
Section 5: Window Size, Checksum & Urgent Pointer
Section 6: TCP Options
Section 7: Data
It is beautifully colorful and well written. Something that can easily be passed on to someone who does not know a lot about networking or as a simple resource to just catch up on forgotten knowledge.
Firewall.cx has huge amounts of very good documentation on it, well worth poking around in for networking people.
I have a lot of files that I keep related to my photography and need to be able to find them again later on. I have given a lot of thought to how to organise the photos so that I can find them by associated categories and based on date.
A few months ago I decided to move away from my flat directory structure, with directories being category names, to something more advanced. I gave the opensource tools available a look and non of them really looked easy enough or powerfull enough to do what I need to do. Someone at worked showed me ACDSee and its great categorisation system and I thought I would use this as the tool to store archive my photos with. I remember ACDSee from the mid 90’s and figured a product this old and mature would be a safe bet.
As it turns out the introduction of the database into ACDSee is by no means mature, I discovered this when the application crashed half way through making a backup and then corrupting it’s database. Some reading of their forums got me to this thread which suggests I am not the only person suffering from this DB issue. I managed to recover the database after hours of messing around and immediatly exported it to a text format. Now I am starting down the road of developing my own archival system.
The full entry contains details of how I store my files, this is as much intended for someone to get some ideas for their own workflow and for me to document how I work so that I can write the archival system to compliment my workflow.
I first came to London in March 2000, we had offices in 1 Canada Square which is the tallest building in Europe at the moment. It was the first building to be built on the Canary Wharf estate. I took a couple of photos with my Epson PhotoPC 600 of the area.
When I discovered these photos again a couple of nights ago I had a look for other old photos around Canary Wharf and found one I took in 2002 from roughly the same angle as the earlier one but just from further away. The 2002 photo was taken with my Olympus C3000 Zoom camera.
Today I went back to the same spot and took another shot with my new camera. Unfortunately I cannot go to the same place as the 2000 photo since there is now a modern flat complex.
The full entry has the 3 photos for a comparison of the growth of this area.
Attached to St. Pancras station in London is a huge victorian Gothic style building, it is the old hotel that was operated by the Midlands Railway. Eventually when the hotel closed it became offices and now its empty but listed as a Grade 1 historic building.
