This post is a follow up to the previous post about creating RAM disks on unRAID and macOS in order to test network transfer speeds. I actually used this method first, as it was the easier of the two and gave me exact transfer rates. The key is to use iPerf3. Installing iPerf3 on unRAID […]
I’ve been playing around with unRAID for about a month now and find it very interesting. I just purchased 2 10 GBE ASUS/Aquantia NICs and wanted to test the network transfer speed. Unfortunately, one quickly finds out the Array and/or SSD cache read speeds become the bottleneck and you don’t see the full 10 Gbps
I was trying to resize a sparsebundle disk image using Disk Utility and kept getting the error that the image resize had failed. The selected disk image could not be resized. Terminal to the rescue. The following command resized my disk image without any issues: hdiutil resize -size XXXg /pathTo/diskimage.dmg Change XXX to the size
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
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. Move to Trash now works as expected. Note: You can implement Delete Immediately… by holding down Option-Command-Delete.
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
I’ve been watching the Developing iOS 11 Apps with Swift podcast (yes, iTunes U content is now available as podcasts, which is cool because you can view them on your Mac) and playing around the Concentration app. This app really wants to be Portrait on an iPhone but Portrait or Landscape on an iPad, given
I’ve been using version 4.0.3 of Octave for some time, installed via the binary available from SourceForge. It works reasonably well, with the exception of having to return to Terminal to enter commands for paged output. I wanted to move up to the current version and managed to get version 4.2.1 installed using HomeBrew. In
I’ve been playing around with prime numbers recently, which (naturally?) extended into an investigation into parallel programming. I installed the latest version of GCC 5 (v5.3.0 at the time of writing) using these instructions and got OpenMP running (support is built-in). I’m fine with using Terminal but I thought it would be interesting to try
For whatever reason, probably because I do iPhone development and am always installing “stuff” on my computer and iOS devices, I’ve run into the dreaded iTunes 3014 error consistently when trying to restore my iPhone/iPad to put a new OS on it. I swear I tried this before and it didn’t work but I just
