4 months ago | Aishwarya Singhal: Aishwarya Singhal

I have been working on Scala in my spare time for the past ~3 months now and I absolutely love it! It is extremely powerful, the syntax is sleek and it has an API for almost every basic operation! My choice of IDE so far has been Eclipse which I am a big fan of while [...]

Lets Play with Scala

7 months ago | Aishwarya Singhal: Aishwarya Singhal

Sometime earlier this year, I read a blog  and an article. These are interesting thoughts and coming from the Java space of enterprise applications, I know exactly how bad performance and unmaintainable the code can get. Scala’s claim of reducing the code by a factor of 2 or 3 is extremely tempting! Add to that a lot [...]

1. Removing a column from a table in SQLite There’s no straight forward way in SQLite so you need to copy the contents into a new table drop and recreate the table and put the data back in. In short, its a big mess. Thankfully rails manages that for us. 2. Creating static data I [...]

Implementing Pagination in Rails

Implementing pagination in Rails is dead easy. I used a plug in called will_paginate. The usual one that’s downloaded when you say “gem install mislav-will_paginate” didn’t work for me.

Ruby, JQuery and AJAX

about 1 year ago | Aishwarya Singhal: Aishwarya Singhal

Since my last post, I got busy with some pressing project work and Ruby on Rails took the backseat. But I picked it up again last week and, as promised, tried a “real” app. Now Ruby is all cool and stuff, but there are gotchas everywhere and I noticed a few that I thought I’ll [...]

The obvious answer to the latter is to use a seperate database schema, but speed? How about an in-memory database? See, now we are [...]
