E July Update

Blog
Another hot and humid work week is coming to an end. It's been raining a lot, and that hasn't cooled things off. It's just steamy. The warm weather won't be around for too much longer, we'll just transition into cold and snowy soon enough. It's a good time to get out and about and try to enjoy the warm weather if you can. I like to have a lite weight laptop with me most of the time, but I'm not too keen on taking a very expensive one out into the somewhat harsh environment. Especially if I can get some productivity out of an older less expensive unit. Looking at the prices on the new MacBook Pro configurations makes me hesitant to upgrade my old MacBook Pro. In fact, I'll usually take my sub $200 IdeaPad or my long in the tooth netbook. They still work, and if either gets dropped or so...
Meltdown – How much will your CPU be affected?

Meltdown – How much will your CPU be affected?

Software, Tech Tips
Meltdown and Spectre were a hot topic this week for anyone who uses a computer. That would be a huge number of affected systems mainly because Intel chips were highlighted as having a design flaw (apparently for many years) that presents a “potential” Security weakness that could be capitalized on for some malicious activity. ARM and AMD chips also are identified as having the same or similar problems. The issue is how the CPU passes control to the kernel operations, then takes control back. Speculative execution is used to increase performance, but due to the CPU vulnerabilities, sensitive data may be exposed. Meltdown affects the isolation between applications and the operating system. This requires hardening the system against any exploits that could leverage these vulnerabilities. Anyw
End of Year

End of Year

Blog
It’s been an interesting year Security alerts, Cyber threats, Fake news, and more critical patch updates than you can shake a stick at. Robots are competing in the job market, A.I is looming, and cold air from the far north is sweeping across the land.  Whether it was a good year, a bad year, or nothing too impressive, it’s just about over now. The new year is coming fast. Are you smarter than you were a year ago at this time? Hopefully, the answer is yes if you put any effort into improving your skills, knowledge, and confidence level. Now you can set down some goals for next year. You can also reflect on your hopes for next year. New Year Goals One of my goals is to continue to improve and refine my command line skills for both Linux and Windows. It’s the same goal every year, but I k

Solus

Software
I thought that I might give the latest Solus MATE a try while I was looking at writing a few words about terminal run file managers. I used it a while back with the Budgie desktop and liked it a lot. It was a great OS for my laptop, but I was spending most of my time using Windows 10, Manjaro, and Ubuntu for some work I was doing and I think I just got distracted and forgot about it. No complaints, just sometimes circumstances send you in odd directions that you hadn’t planned on and some things get left behind. Anyhow, I was listening to the Late Night Linux podcast  https://latenightlinux.com/  the other day and remembered that I kind of liked that Solus “OS”. I probably shouldn't refer Solus as a spin or Distro since I believe it’s built as an Independent development. (not directly b
Nigel’s performance Monitor for Linux (nmon)

Nigel’s performance Monitor for Linux (nmon)

Tech Tips, Software
Linux has many available tools that simply just work. That’s why I prefer it over other operating systems. I can get things done, usually faster and much simpler from a command line in a terminal, or multiple terminals. Windows has useful and powerful shells, and I use them when I need to work on that OS, but I prefer to work in bash. I make use of simple, but elegant installation applications, most notably Apt and PacMan - depending on which of my two preferred distros I have installed. I can install simple, but powerful tools to pull out information about my system’s operation and performance. nmon: One of my goto tools is nmon. (Nigel’s performance Monitor for Linux) - originally used by IBM and released as open source in 2009. I wouldn’t categorize “nmon” as old school, but it
