Day 2 at dev8D 2010 – Lightening talks and Ruby on Rails coding lab
I attended the Ruby on Rails code lab and the following lightening talks:
- Cloud Computing – University of Southampton
- Interacting with the public data store (http://data.gov.uk)
- Web security – Ben Charlton, University of Kent
- Stay the hell out of pear_lib
- Symbian apps get started
- iPhone – Spotlight Kid
- Genetic algorithms
- Manufacturing for the masses – RepRap
- Stay out of core code at all costs, extend using plugins
- Check out OWASP top 10 tips web security tips
- Don’t save back up config files in the web root, for instance config.php.bak will be readable
- Symbian apps are easy to make
- RepRap rocks!
- Django handles configuring paths better than Ruby on Rails
Manufacturing for the masses, RepRap notes
A fantastic 3D printer that can create plastic mouldings.
- can print 50% of own parts (in 2.5 days)
- most non plastic parts are widely available
- costs approx €350
- future aims to be able to shred and recycle your own plastic bottles or use starch based sources
Some commercial outlets, such as Bits from bites, make t machines that don’t replicate themselves, but can replicate parts for a RepRap machine.
