  The 5 types of programmers

In my code journeys and programming adventures I’ve encountered many strange foes, and even stranger allies. I’ve identified at least five different kinds of code warriors, some make for wonderful comrades in arms, while others seem to foil my every plan. However they all have their place in the pantheon of software development. Without a healthy mix of these different programming styles you’ll probably find your projects either take too long to complete, are not stable enou...

  Functional Programming Is Hard, That's Why It's Good

Odds are, you don’t use a functional programming language every day. You probably aren’t getting paid to write code in Scala, Haskell, Erlang, F#, or a Lisp Dialect. The vast majority of people in the industry use OO languages like Python, Ruby, Java or C#–and they’re happy with them. Sure, they might occasionally use a “functional feature” like “blocks” now and then, but they aren’t writing functional code.And yet, for years we’v...

  Gaussian Blur Algorithm

Usually, image processing software will provide blur filter to make images blur. There are many algorithms to implement blur, one of them is called Gaussian Blur Algorithm. It utilizes Gaussian distribution to process images. This article is to introduce Gaussian Blur algorithm, you will find this is a simple algorithm. In fact, it is a kind of data smoothing which can be used in many situations. 1. Gaussian Blur theory The so called blur can be understood as taking a pixel as the average valu...

  The Golden Age of Design in Startups

I just returned from Dave McClure’s excellent Warm Gun Conference, and I haven’t been this excited to be a designer in a while. The entire event was about design, metrics, and products, and even more importantly the people at the conference were many of the who’s who in Bay Area design. From what I saw and experienced there I daresay there are signs we’re entering a golden age of Design. The evidence: 1. The startups being invested in are designer-led. Take the...

  Server monitoring shell scripts

There are many open source server monitoring software such as cacti and nagios. Besides these, can we write our own shell scripts to monitor them? The shell scripts written by ourselves can fulfill our special requirements better and have a more detailed coverage. Below are some commonly used shell scripts used by Evangelist, an Oracle DBA. 1. Check network gateway traffic #!/bin/bash #network #Mike.Xu while : ; do time='date +%m"-"%d" "%k":"%M' day='date +%m"-"%d' rx_before='...
