  • Story Type: News Story
If you've lived through a major, natural disaster, you know that during the first few days you'll probably have to rely on a mental map, instead of using a smartphone as an extension of your brain. Where's the closest hospital with disaster care? What about shelters? Gas stations? And how many soft story buildings—with their propensity to collapse—will you have to zig-zag around to get there? read more

Do Linux distributions still matter with containers?

Some people say Linux distributions no longer matter with containers. Alternative approaches, like distroless and scratch containers, seem to be all the rage. It appears we are considering and making technology decisions based more on fashion sense and immediate emotional gratification than thinking through the secondary effects of our choices. We should be asking questions like: How will these choices affect maintenance six months down the road? What are the engineering tradeoffs? How does this paradigm shift affect our build systems at scale? read more

Cat-Proofing Your Screen Locker with Bash

by Mitch Frazier   I have a computer in my bedroom. I also have cats. Unfortunately, cats and screen lockers don't mix well, particularly at night. To be accurate, it's more a problem with the display power management than the actual screen locking. Here's the way it works: I run a script to "shut the lights off at night" (that is, lock the screen and force the display to power down), and that works great, until one of the cats jumps on the desk and causes the mouse to move and turn the display back on. And the cats don't even have to touch the mouse; the slight movement of the desk is enough to cause the mouse to react. Recently, I'd had enough of it and figured there had to be a way to disable the mouse and "refactor" the script.

Infrastructure monitoring: Defense against surprise downtime

Infrastructure monitoring is an integral part of infrastructure management. It is an IT manager's first line of defense against surprise downtime. Severe issues can inject considerable downtime to live infrastructure, sometimes causing heavy loss of money and material. Monitoring collects time-series data from your infrastructure so it can be analyzed to predict upcoming issues with the infrastructure and its underlying components. This gives the IT manager or support staff time to prepare and apply a resolution before a problem occurs. A good monitoring system provides: read more

When you think of the word wiki, chances are the first thing that comes to mind is Wikipedia. That's not a surprise, considering that Wikipedia did help put the concept of the wiki into the popular consciousness. Wikis, which are websites you can edit, are great tools for collaborating and organizing. But wikis usually require a lot of digital plumbing and a bit of care to use and maintain. All of that's overkill for personal use. read more
