I typically cover software packages that do actual calculations to advance scientific knowledge, but here I'm exploring a slightly stranger tool in the arsenal of scientific computation.

Linux Journal was a print magazine for 17+ years, then a digital one for the next 7+. What shall we be now? That's the Big Question, and there are many answers, some of which are already settled.

It was the summer of 2007 and I was at Linux World Expo in San Francisco. I had just finished updating the second edition of Knoppix Hacks and in addition to attending the conference I was there to promote it and my other books at the O'Reilly booth. Somehow I got word that Linux Journal was looking for new authors and was holding an event at a nearby bar later that day.

More than ever, small to mid-sized businesses demand and rely on their networks to carry out mission-critical business activities. As always, however, budgets and expertise constrain these companies from using complex managed switches to run their networks.

I've covered scientific software in previous articles that either analyzes image information or actually generates image data for further analysis. In this article, I introduce a tool that you can use to analyze images generated as part of medical diagnostic work.

I've been installing a lot of POE devices recently, and the different methods for providing power over Ethernet cables can be very confusing. There are a few standards in place, and then there's a method that isn't a standard, but is widely used. 802.3af or Active PoE:

In my last few articles, I've written about data science and machine learning. In case my enthusiasm wasn't obvious from my writing, let me say it plainly: it has been a long time since I last encountered a technology that was so poised to revolutionize the world in which we live.

In the April 2017 issue, I wrote about how to use ticketing systems as a sysadmin to organize your tasks better.

I've covered several scientific packages in this space that generate nice graphical representations of your data and work, but I've not gone in the other direction much. So in this article, I cover a popular image processing package called ImageJ.

Zero downtime is, of course, a mythical holy grail. According to IDC senior market analyst Prabhitha Sheethal Dcruz:
