Setting the To value: cell in Excel’s Goal Seek to a Cell Reference
Sadly, it took awhile to “figure” this out. I was trying to solve a set of equations in Excel. I had one equation in one cell, say B1, that had a dependency on the value in A1. I had the second equation in cell C1 that also has a dependency on A1. I wanted to

pydotplus on macOS
I’ve been playing around with SciKit-Learn’s decision tree regression function. In one of the examples I was working on, they provided a demo script to print out a jpg of the decision tree. Cool! Unfortunately, my system didn’t have pydotplus installed. I’m using Anaconda, so issuing the following command took care of that issue: conda

Move to Trash Deletes Immediately
I had this issue when I first updated to macOS Mojave. To solve it, I performed the following command in Terminal: sudo rm -Ri ~/.Trash [enter your password] Then, Log out. Log back in.

Change: $mail = new PHPMailer(); To: $mail = new PHPMailer\PHPMailer\PHPMailer(); I’ll post (or edit this post) a

FTP on macOS High Sierra
As you may have noticed, FTP is no longer a part of macOS High Sierra. If you are in the Terminal, you’ll get something like this: Norms-iMac-Pro:~ norm$ ftp -bash: ftp: command not found An Apple Forum’s post has this reasoning. Fortunately, there is Homebrew to the rescue. As pointed out in that post, you

Installing GCC-7.3.0 on macOS High Sierra
I talked about getting GCC-5.3.0 running in a previous post. As part of some benchmark testing I’m doing for a new computer build, which I hope to write about in a future post, I ventured back into the world of parallel programming. I used the excellent instructions from Solarian Programmer found here to get GCC-7.3.0
