Wanelo Tech Blog: The Big Switch: How We Rebuilt Wanelo from Scratch and Lived to Tell About It

Just published my first contribution to Wanelo Blog on the subject of rewriting technology stack from scratch, and moving from Java to Ruby.

Feel free to leave comments here also!

Inspiring. What makes it more interesting is that you started it from scratch which I find very difficult to do. So, good job for that.

@Sing you clearly did not even read the post, did you? Because the answer to your moronic question is the subject of the entire blog post. Doh!

Car or Auto Make-Model-Year Database : For Breakfast

Make Model What?If you like me were tasked with loading a database of recent car makes/models/years, you would start by looking on the web and seeing if someone else just has it out there, readily available, hopefully for free, but perhaps for a tiny nominal fee.?If only it was that simple... I looked and looked, and couldn't find anything that would fit the above requirements. So I thought, who would know about US car models better than Kelly Blue Book? So I went on their site, and sure enough they have a javascript file that lists all known to them makes and models of used cars. Since the file is public, I figured it's not really "evil" if I scrape and parse it for my own benefit. Disagree? Have a better source? Then leave a comment.Anyway, to cut the long story short, I'm hoping to save a day or so to someone else who may, like me, be looking for this information. The ruby module shown below retrieves and parses the javascript from KBB site into a Ruby da…

On Ruby on Rails with PostgreSQL, and Acts as Paranoid

Back a few years ago I was researching differences between PostgreSQL and MySQL databases, and chose PostgreSQL because at the time it supported foreign key constraints and many other fantastic SQL extensions that make developer's life a lot easier. Today I am sure MySQL is just as functional as PostgreSQL, and it does appear to be a more popular choice as the Rails DB than MySQL. I still prefer PostgreSQL, it just feels more natural to me coming out of Oracle background, so I am probably biased (who isn't?) Anyway, in the last year and a half or so, I've been writing Rails apps that use PG-based databases and found a few random tricks I'd love to share here. Opinions differ here, but just like accountants like the ancient double entry accounting system, I personally prefer a double validation system - where Rails validates my objects before/after updates, but the database double checks this using proper constraints. Rail's validation system is very robust and ext…

Ruby on Rails Hosting: From HostingRails to RailsMachine in a shake of a tail

Rails hosting is a hot subject, and with everyone asking everyone else about their experience, I thought its only fair to share my own experience, even though it is relatively limited. Introduction I started with a shared "professional" hosting plan from HostingRails. It was around $30/month, and included non-root SSH access to a shared server, and additional 150Mb of RAM for total of 200Mb (although that's actually quite misleading, see below). I stayed on this plan for about 3-4 months, and then decided to switch to a virtual hosting plan from RailsMachine - their single server plan, for about $100/month (that includes dedicated 384Mb of RAM and a root access to my virtual server). This post describes the reasons behind switching, and compares pros and cons of each hosting plan. Our needs included the following setup: One application running in two instances (one production, and one test) Two-mongrel instances per application (so total of 4 mongrels) Capistrano base…
