Convert documents with Pandoc like a pro

Has anyone ever sent you a document in a format that just isn't quite right for you? Maybe you don't have access to the application used to create the document, or maybe you don't need the document so much as you need what's in it, or maybe you just flat out don't like the format. There's no wrong reason for disliking a file format. If it's not your preferred format, whether you find it cumbersome to use or you just don't like how its metadata is organized, then that's enough of a reason for you to convert it.

How to find new maintainers for your open source project

If there's one thing you can say about open source software (OSS), it's that it quietly yet inarguably runs our world. Most of the internet is built on open source software, and, these days, millions of developers build and maintain hundreds of thousands of open source packages in more than 250 programming languages. If that's not enough, enterprise companies continue to grow their investments in open source in 2020.

Serial communication on modern Linux

  • Groups: Linux; Story Type: News Story
As a systems engineer, I spend a lot of time in data centers configuring servers and other computer equipment. Two of the items I keep in my toolkit are an RS-232 serial-to-USB converter and a standard DB-9 serial cable. These can be indispensable when you have no other way to access a device. You may need to deploy a new router that has not yet been configured for your network. You might need to troubleshoot a firewall appliance that has become inaccessible via SSH. read more

Tips and tricks for optimizing container builds

  • (Posted by bob on May 13, 2020 9:10 PM EDT)
  • Story Type: News Story
How many iterations does it take to get a container configuration just right? And how long does each iteration take? Well, if you answered "too many times and too long," then my experiences are similar to yours. On the surface, creating a configuration file seems like a straightforward exercise: implement the same steps in a configuration file that you would perform if you were installing the system by hand. Unfortunately, I've found that it usually doesn't quite work that way, and a few "tricks" are handy for such DevOps exercises. read more

  • Story Type: Security, Tutorial; Groups: Linux
Have you ever thought about how secure your Linux machine really is? There are numerous Linux distros, each with its own default settings, on which you run dozens of software packages with different version numbers, and numerous services running in the background, which we hardly know or care about. To find the security posture—the overall security status of the software, network, and services running on your Linux machine—you could run a few commands and get bits and pieces of relevant information, but the amount of data you need to parse is huge.
