Half of New York City’s best and brightest technologists live or work in Brooklyn, yet we travel to Manhattan every week for the best tech talks.

Not anymore! BK Tech Talks are presentations about the most interesting problems and solutions that New Yorkers are working on.

Presentations should be 30-45 minutes long and are for a technical audience. Don’t be afraid to show source code. And if you’re afraid to read code, this Meetup isn’t for you. If you would like to present or there’s something you’d like to hear about, please let us know.

The first few presentations: “MTA BusTime: Real Time GPS Tracking of New York City Buses” and “Bitcoin is Not a Currency” look awesome.

So? What are you waiting for? Come join the Meetup and we’ll see you in Brooklyn!

In a fresh commit, Rails edge now has the ability to automatically add query plan info to the standard Rails logger:

# Log the query plan for queries taking more than this (works
# with SQLite, MySQL, and PostgreSQL)
config.active_record.auto_explain_threshold_in_seconds = 0.5

… which will yield something like:

+----+-------------+-------+-------+---------------+---------+---------+-------+------+-------------+
| id | select_type | table | type  | possible_keys | key     | key_len | ref   | rows | Extra       |
+----+-------------+-------+-------+---------------+---------+---------+-------+------+-------------+
|  1 | SIMPLE      | users | const | PRIMARY       | PRIMARY | 4       | const |    1 |             |
|  1 | SIMPLE      | posts | ALL   | NULL          | NULL    | NULL    | NULL  |    1 | Using where |
+----+-------------+-------+-------+---------------+---------+---------+-------+------+-------------+
2 rows in set (0.00 sec)

Hot.

A little shell script that lets you generate sparklines at the command line:

spark 0 30 55 80 33 150

You can also pipe stuff to spark—see this wiki page for some clever examples.

This is pretty cute.  I like the idea of putting inside your prompt, think there’s some interesting information you pull to put there.

Maybe a graph of how many times you had to run `sed` to actually get your prompt to render?

A trigger is an action that is performed when text matching some regular expression is received in a terminal session.

What can Triggers Do?

Various actions may be assigned to triggers. These include:

• Bounce Dock Icon: Makes the dock icon bounce until the iTerm2 window becomes key.
• Ring Bell: Plays the standard system bell sound once.
• Run Command: Runs a user-defined command.
• Run Coprocess: Runs a Coprocess.
• Send Growl Alert: If Growl is enabled, a Growl alert is sent.
• Send Text: Sends user-defined text back to the terminal as though the user had typed it.
• Show Alert: Shows an alert box with user-defined text.

iTerm2 is so frackin’ cool
