Commited Facebook Suicide for the second time. Where do I start? … The first thing that jarred me was that my full birthday is published. This in combination with search engine visibility means that it’s spammer time. Next thing that happened is that the privacy settings had “Everyone”, “Friends of Friends”, and “Friends”. Nice and simple, I thought. But no, I have to exclude my full birthday again from everyone. (I know about how your friend’s applications can just mine everyone’s data through friends).
I have a problem where a project is using an older version of RSpec (currently the lastest version is RSpec 1.3.0). Therefore running spec spec/model/some_model_spec.rbgives me an error /spec/models/../spec_helper.rb:23: undefined method `use_transactional_fixtures=’The solution would be to use the older, vendored spec. Now, the spec binary that is installed as part of the gem installation should do this (some gems do checked for vendor’ed binaries) and my rspec is installed under vendor/plugins, not vendor/gems.

Some good Software Engineering pearls of wisdom : Coding Horror: The Xanadu Dream The bottom line is that a lot of the time it’s OK to create a solution that solves 80% of the problem. Always remember that shipping is a feature. Agile development, startups and government policy My recommendation to just about anyone with an idea is to just build the thing, iterate until you have some user traction, then pitch angel investors based on that traction.
Reading this article about Wellington Hazards just makes me want to plot it on a map. It took a while, but here is a map of Wellington Hazards / Contamination. Below is a screenshots of the hazards on Google Earth and Google Maps (Google Earth shot nicely prepared by Cameron). Let me know what do you think? Read on after the jump for hyper-technical explanation of how I made the map.
Came upon this really good post about people you should cherish: Rands In Repose: Your People Really good insight - “As we edit our days into these stories, there is always a risk of fiction. This is why you need to identify and nurture Your People.” What are Your People? “You tell these stories to Your People without reservation. Your People love your stories — fiction and all.
