Sending Emails from CSV/TSV Formatted Data through Gmail SMTP by Ruby

A Japanese version of this document is in TechRacho. I want to send e-mails to my students from my Excel-formatted list. I don't have any SMTP servers so that I use Gmail SMTP. The advantage of this program is:

• Email from your tabular data (Excel, CSV, TSV, etc.)
• Using Gmail SMTP (you don't worry whether your server is in spam blacklists)
• Customizable mail template, no Ads

This program is verified on Ruby 1.8.7 + ActionMailer 3.0.3 + fastercsv 1.5.4 + tlsmail 0.0.1.

[Eclipse]: Autocomplete Feature Shows only "No Default Proposals" on Eclipse

A Japanese version of this document is in TechRacho. I got new MacBookAir (Mid 2011, Lion) and build my development environment from scratch. When I installed Eclipse 3.7.0 + ADT, the code assist feature (autocomplete) does not work. It shows only "No Default Proposals" and no any other nominations available.

I solved this problem. This may not be ADT dependent, it may apply to all other Eclipse-based IDE.
