The posts are text only so the memory usage doesn't grow very fast. You can post images using Markdown but the images themselves have to be hosted elsewhere. I've created a few million posts on a development laptop and the memory usage was not bad (can't remember the exact number).
Right now there is no memory limit or handling for when memory reaches a certain point. Pruning based on FIFO or fewest replies could work, or OS level techniques to handle memory limitations like swap.
I will add some screenshots to the repo. Thanks for the suggestion.
The bigger problem is that the amount of information you can consume using RSS feeds is declining. Most sites don't publish RSS feeds of their content any more.
Sadly RSS is left over from a time when things were more open. Now everything is an app and everyone wants you to stay in their walled garden.
Having a baby caused me to transition to this style for personal projects. I spend a lot less time in front of the computer now and when I do it's for shorter times.
I've found this approach does give a better result and eliminates false starts. When I'm at the computer now I have already thought through what I'm going to do completely and writing the code is just a minor detail.
Open source router firmwares like DD-WRT or Android handsets would be good platforms for some kind of mesh network.
Having a wireless AP with a webserver and forum software would be a simple option for communicating with your immediate neighbors (who could communicate with theirs).
CPAN is large and comprehensive but every time I've had to use it I've had to watch a minimum of 20 minutes of scrolling compilation, installing dependencies and running tests. Ruby and python install what I need in a few seconds so I can get back to work.
Maybe it's a question of perl putting a lot of things in CPAN versus other languages putting more in the standard library?
It's regex search the of the url itself and the page title. It doesn't match against the full document if that's what you mean. That's an interesting idea though.
