Currently, the Abstractions II conference, which
starts next week, requires all attendees to wear a wristband with an RFID tag
in it for the duration of the conference, including in bed and in the bathroom.

data will be handled. Please share this and
contact the organizers.

Shortly after I published Benchmarking

with a correction. It turns out the approach Jonathan and I used to time how

UPDATE: The test methodology is flawed! PostgreSQL can be faster than nodejs.
See the follow-up article.
Jonathan New wrote an interesting article on UUID creation in Postgres vs
Node. In it, he described the
performance tradeoff of generating a
UUID in the
database vs in the application. It's not very …
In order to set a strong password for the PostgreSQL database I provisioned on
Amazon RDS, I looked up the limits. In my case, there are two sources of
constraints:
I am building a web application that delegates authentication to a third party.
Once the third party authenticates the user, the app create a session for the
user - and maybe create the user, too, if they don't already exist!
My first draft of this had all the SQL queries in …
There was a particular moment when I realized I was very much a junior
developer.
Now, in school, I have done very well. I do well in my classes, I'm proud of
the code I write, and when I've worked with others I think I've been a
productive and active …
A year ago, I was learning about unit tests. I was also taking a compilers
course.
When I sat down to work on the first homework, I wasn't really in the mood.
Instead, I messed around with writing a test suite. When I couldn't think of
any other tests to …
