Just a quick tip to revive the blog from a month long silence. I am alive and kicking. I have been occupied with a quest to rescue princess & maidens on video game console.

As it is almost summer, I am also enjoying the beautiful outdoors in Wellington. All this means, little time for blogging. I will try to post a few more times before the end of year.

Unfortunately, you can’t convince VLOOKUP to act nice.

Hey VLOOKUP, I know you are awesome and all, but can you cut me some slack here?
