What it takes to be a Web Developer

Did a lightning talk for DevCon DLSU last Wednesday. Not really liking the end result. My decision to deliver it in English is mainly to blame: I wrongly guessed that La Salle students would react better to English than Tagalog (the latter I prefer when giving talks), and all I got from it was having my lack of practice look more obvious.

I think the worst part about my talk was the way how the “sarcastic-whiny-tone” I use in my normal everyday Tagalog creeped into my usually more professional sounding English voice. I’ll probably have to do weeks of voice retraining to eliminate that. =/

Anyway, here is the video of the talk as well as the slides.

Notable CD-R King Items Holidays 2011 Edition

It’s been almost two and a half years since my post about hidden gems within the multitude of (often crappy) products found in CD-R King. Since that post, I’ve found a couple of new interesting finds worth a blog post.

No, there won’t be any obvious things here (e.g. the laptop, netbook, tablet, etc). I prefer not-so-obvious items that are mostly relevant to my interests.

RailsFTW v0.9 released, now with Rails 3.1

Thanks to a Battlefield 3 Beta losing streak that I blame on my sucky internet connection, I’ve decided to update my hack-job of a standalone Windows installer for Rails.

Now there are two separate installers, a Ruby 1.8.7 + Rails 3.0.10 installer and a Ruby 1.9.2 + Rails 3.1.0. Here’s a table to give a quick comparison between these two installers with RailsInstaller thrown into the mix:

	RailsInstaller 2	RailsFTW (Rails 3.1)	RailsFTW (Rails 3.0)
Ruby version	1.9.2-p290		1.8.7-p352
Rails version	3.1.0		3.0.10
File Size	~55MB	~20MB	~10MB
DB Adapter Gems	sqlite3, pg, tiny_tds (MS SQL Server)	sqlite3, mysql2
Additional Features	git, DevKit	–
Internet Connection Required?	Yes	No (Bundler will fail to connect to server but new apps will still work)	No
Compiled by	Some of the biggest names in the Ruby community	Some random third world developer. LOL

Take periodic screenshots in Ubuntu with scrot and cron

I had to log my hourly effort in my last gig (stupid policy IMO; what am I, a factory worker?) but since I’m not working on Windows, I couldn’t use ManicTime to do the tracking for me.

Taking a cue from oDesk, I decided to make a simple script that takes screenshots of my desktop every few minutes so that I could just review them at the end of the day. For this I used scrot for taking the screenshots and cron for the scheduling.

First install scrot:

$ sudo apt-get install scrot

Then write a script, say /path/to/home/scrot.sh:

#!/bin/sh
LOCATION="$(date +/path/to/home/Pictures/shots/%Y/%m/%d)"
mkdir -p $LOCATION
cd $LOCATION
DISPLAY=:0 scrot '%Y-%m-%d-%H%M.jpg' -q 20

This script will take a low quality screenshot of the desktop and put it in the Pictures/shots folder separated by date.

Set the permissions with chmod:

$ chmod u+x /path/to/home/scrot.sh

You can now test this by running:

$ /path/to/home/scrot.sh

Now time to add the script as a cron job. There are a lot of cron tutorials out there, but to summarize what you need to do, here are the basic steps:

Run crontab -e to edit the cron table file for your current user.

Add a line that will execute scrot.sh whenever you want it to run. For example, here’s the entry for running the script every three minutes on Monday to Friday:

*/3 * * * 1-5 /path/to/home/scrot.sh
