Soon after, I started asking questions on dedicated forums, learned how to use IRC to chat with developers, and contributed my first bug reports. As my contributions increased, I made a career move from industry to open source software. Over the past 20 years, I've learned a lot about using and contributing to free and open source software and working with communities and developers. Here are 10 of the key areas you'll find in an open source project and some tips for managing them better. read more

Recently, Andrey Ryabinin tried to fix what he felt was a problem with how CGroups dealt with low-memory situations. In the current kernel, low-memory situations would cause Linux to recuperate memory from all CGroups equally. But instead of being fair, this would penalize any CGroup that used memory efficiently and reward those CGroups that allocated more memory than they needed...

Since ancient times, we've known that one of the most effective ways to learn something is by teaching it to someone else. I've put that strategy into practice by teaching Python in my community. If you want to learn Python for free and have fun at the same time, I recommend you consider doing the same. read more

If you last updated your IT security standards five or more years ago, chances are they don't line up well with the realities of today's DevOps and site reliability engineering (SRE) practices. One particularly sticky topic is testing in production—and, thus, testing with production data—because DevOps and SRE blur the line between what is production and what is not; what is a test and what is not. To clear up some of the confusion, we'll dig into these questions: read more

Business documents often require special handling. Enter Electronic Document Interchange, or EDI. EDI is more than simply transferring files using email or http (or ftp), because these are documents like orders and invoices. When you send an invoice, you want to be sure that: 1. It goes to the right destination, and is not intercepted […]

Suppose you wake up one day and decide to finally use that recipe video you keep watching all over social media. You get the ingredients, organize the necessary utensils, and start to follow the recipe steps. You cut this, cut that, then start heating the oven at the same time you put butter and onions in a pan. Then, your phone reminds you: you have a dinner appointment with your boss, and you're already late! You turn off everything and leave immediately, stopping the cooking process somewhere near the end.
