How to avoid humiliating newcomers: A guide for advanced developers

Friday 16th of March 2018 07:01:00 AM

Every year in New York City, a few thousand young men come to town, dress up like Santa Claus, and do a pub crawl. One year during this SantaCon event, I was walking on the sidewalk and minding my own business, when I saw an extraordinary scene. There was a man dressed up in a red hat and red jacket, and he was talking to a homeless man who was sitting in a wheelchair. The homeless man asked Santa Claus, "Can you spare some change?" Santa dug into his pocket and brought out a $5 bill. He hesitated, then gave it to the homeless man. The homeless man put the bill in his pocket.

5 open source card and board games for Linux

Wednesday 14th of March 2018 07:01:00 AM

Gaming has traditionally been one of Linux's weak points. That has changed somewhat in recent years thanks to Steam, GOG, and other efforts to bring commercial games to multiple operating systems, but many of those games are not open source. Sure, the games can be played on an open source operating system, but that is not good enough for an open source purist.

You may be familiar with The FreeDOS Project. FreeDOS is a complete, free, DOS-compatible operating system that you can use to play classic DOS games, run legacy business software, or develop embedded PC applications. Any program that works on MS-DOS should also run on FreeDOS.

Can we automate open behaviors?

Tuesday 13th of March 2018 07:00:00 AM

When I began studying sales training and giving sales seminars, I realized I was discovering a few basic principles. These principles were applicable anywhere in the world—and they were as true in the past as they will be in the future.
