All Horses Are the Same Color
Problem: Show that all horses are of the same color. “Solution”: We will show, by induction, that for any set of $ n$ horses, every horse in that set has the same color. Suppose $ n=1$, this is obviously true. Now suppose for all sets of $ n$ horses, every horse in the set has the same color. Consider any set $ H$ of…

Why Go is elegant and makes my code elegant
This is a enthusiast blog post. I’m not even gonna speak about how concurrency comes easy with Go. Honestly, I’m not good enough to speak about it. I’ll just speak about how using Go in my everyday programming makes me happy.

Backend for Front-end
In the good old days, applications were simple. A browser sent a request to a webapp endpoint; the latter fetched data from a database and returned the response. The rise of mobile clients and integrations with other apps upset this simplicity. I want to discuss one solution to handle the complexity in this post. The…

TDD Doesn't Work
Yeah, an in-depth study that repeated another study that was done a few years back. Both showed that TDD doesn’t work. The new one uses a multi-site, blind analysis, approach. It looks conclusive.

Lifetimes of cryptographic hash functions
Quick summary of my recommendations on compare-by-hash: If you are using compare-by-hash to generate addresses for data that can be supplied by malicious users, you should have a plan to migrate to a new hash every few years. For example, BitTorrent falls into this category, but rsync doesn't. Keep in mind that new…

A Look at Rust from 2012
Recently I was scrolling through brson’s Rust quote database and stumbled upon a link to the official Rust tutorial from the very beginning of 2013.

A dive into the AMD driver workflow
I ended up getting a response from high level people at AMD. It was still very light on any real technical information, but it did include some great phrases like “I am able to replicate the issues you are facing” and some mockable phrases like “We are hoping that this will improve your perception of AMD products and…
