Waiting For Darkness | Julia Programming Language

The nights will soon be growing longer as the dog days of summer draw to a close and we slowly ease closer to Fall. Cooler nights, rain, and wind will become the norm. We retreat to the inner sanctum with the radio (podcasts) playing in the background. A hot cup of coffee, dim light on above the workbench, trusty low powered laptops displaying simple terminals which facilitate exploring the possibilities of learning some new tips and tricks. No GUIs to distract into a mindless point and click wandering. Cold dark dreary weather is perfect for perusing through some deep technical papers, thick computer books (yes, actual books made of paper and ink), or “help” files often neglected but often associated with our favorite coding language, IDE, or debugging programs. Like Alchemists searc...

Weather Data

Recent Posts, Tech Tips
Weather alerts, weather Alerts, notifications everywhere. The iPhone notifications from multiple weather apps are handy, and when you hear the notification alerts from other people’s phones going off around you, you’re going to look at your screen. Something is going on, or soon will be. In the old days, we listened to our radios for weather forecasts, often the local television station weather broadcast. Later on, the soothing sounds of the Weather Channel’s greatest hits played while our local forecast rolled across the screen in-between weather people pointing to a green screen and looking off-camera to create a less confusing presentation illusion. It all worked very nicely. Now we can view the weather in our computer browsers or on a phone app.You can easily view the weather in...

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...
