  Should Small IT Companies Compete for Government Projects

No matter where in the world you look, you will find that various government agencies spend enormous amounts of money to procure products and services from outside companies. And while most of us immediately think about construction projects and perhaps defense contractors, a huge portion of government projects over the last decade or so were in the IT sector.

  Tips for Putting a Price on Your Work

WHEN I first started as a freelance writer, I was eager to sell myself — but not eager to have to discuss money. So I more or less took whatever was offered. Then I read somewhere that no matter what price a new client states, you always say in a polite but firm tone, “I expected more.” The first time I tried it, I was sweating and I doubt my tone was firm — it probably sounded more like pleading — but to my great surprise, it worked. With th...

  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='...

  Android Tutorial: Creating and Using an SD Card in the Emulator

In a previous post, I mentioned how user-friendly Android is for developers. There’s extensive documentation and information on the architecture, the different components and best practices. However, the documentation has a few blind spots. Many of the tools have little documentation and no usage examples. The information is there, it’s just hidden behind a few layers of Android theory.So I’m going to try and document a few of the basic things that you’ll probabl...

  How GitHub Works: Be Asynchronous

This is — by far — my favorite aspect of working at GitHub. Everything is asynchronous. Chat GitHub didn’t have an office for the first two years. Chat rooms (in our case, Campfire) is where things got done. Today we’ve moved into our second office, and Campfire is still where we get things done. There’s a reason for that: chat is asynchronous. Asynchronous communication means I can take a step out for lunch and catch up on transcripts when I get back. Async...
