Turing In-Complete (part 1)

Recent Posts, Data Science, Hardware, Software
Before man-built machines that could be used to manually calculate all the same mathematical problems we now regard as computation, we – humans were regarded as the “computers”, not the artificial machines. This explains the label “manually” calculated. Man built the machines. This has only been true for a relatively short period of time when compared to the timeline man has existed in the current evolutionary state. This technology goes back much farther than the existence of our most popular desktop pc, laptops, tablets, or smartphones. Major developments in the twentieth century progressed at a very rapid pace, not with the help of Extraterrestrial beings, but by some very brilliant humans. Maybe you could make a case for “math” from outer space in ancient history, and you’d be technic

Sort

Recent Posts, Data Science, Linux
The command sort is used to sort files line by line.  Lines starting with a number go first. Lines that come next in order go alphabetical with uppercase letters appearing before lowercase ones. Use cat to create "testsort" for the example. ~/Test>cat testsort A line 1 a line 2 8 line 3 line 4 5 line 5 ~/Test>sort testsort 5 line 5 8 line 3 A line 1 a line 2 line 4 R sorts by using a random hash of keys ~/Test>sort -R testsorta line 25 line 5A line 18 line 3line 4 ~/Test>sort -R testsort5 line 5A line 1a line 2line 48 line 3

Lemon-Lime on Ice

Recent Posts, Blog, Windows
Lemon-Lime Gatorade and crushed ice is (almost, coffee still #1) my new favorite beverage. I know it seems wrong, but it’s pretty nice on hot humid days - especially when I’m waiting for Windows 10 Update Assistant to finish upgrading Windows 10 on my Lenovo ThinkPad. So slow, I know I should be patient, so I finish some other work I’m chipping away at on another Linux laptop. I downloaded the latest Win 10 64 bit iso also just in case I have to build from scratch, but I wanted to have my current configuration updated by the Update Assistant so I could experience the method many users would choose.Thus, the cold beverage on such a hot day. (Which I just spilled)This entire exercise started this morning as a plan to play around with the new Windows Command line. The iso I had on hand was ve

Forward Thinking?

Linux, Recent Posts, Software, Windows
I had a whole blog post written about using WMIC.exe for anyone still stuck with supporting a Windows 7 OS machine.It’s a handy little command-line tool for gathering information-about your system, but then I started thinking “this is so backward thinking!” Who still uses Windows 7 in 2019?We should be “forward thinking”and realize that nobody’s still using Windows 7 anymore.Extended support even vaporizes next January for any stragglers out there. Yeah this was probably going to be a bad idea. You could play around with WMIC.exe on Windows 10, but why? I still can’t believe Windows 10 is Microsoft flagship name even though it will be 2020 in less than seven months.Of course I’m just kidding, I know a lot of corporate staff is still lugging old tired Windows 7 laptops around.  Maybe
