Installation of Blazor on Mac OS X

October 31, 2020 by Nathaniel Avery in Install, Basics

Blazor is a feature of .Net that allows for client-side web applications to be built via CSS, HTML, and C#. Apps written in Blazor can be written on almost any platform, including the Mac. This blog post walks through the installation process as documented on the MS Blazor Tutorial website.

Blazor’s tech stack is part of Microsoft’s .Net developer platform. Because of that, the first thing we need to do is install the .Net Software Developer Kit (SDK).

Install CentOS 8 on VMware Fusion 11.5 Error - Pane is Dead

January 24, 2020 by Nathaniel Avery in Bugs

Problem:

Installing CentOS 8 on VMware Fusion 11.5 produces an error.

“Pane is dead” appears at the bottom of the screen. Rebooting doesn’t make the problem go away.

Solution:

The easiest solution I can find is to conduct a custom install selecting Red Hat 8 as the OS and set the BIOS type to UEFI. When the virtual machine boots, attach the CentOS 8 .iso file, reboot, and continue the install as normal.

Root Cause:

As best I can figure it, the root cause seems to be tied to how Fusion identifies CentOS 8. Fusion appears to identify it as “CentOS 5 or earlier 64-bit” which has either hardware settings, drivers, or both, that are incompatible with the CentOS 8 installer.

Edit:

While I used UEFI, the custom install option will also work with “Legacy BIOS” selected.

Troubleshooting - AWS EC2 - "Load key '/documents/awskey.pem' : bad permissions

November 27, 2019 by Nathaniel Avery in Bugs, Tip

Problem:

This error is encountered when attempting to connect to an EC2 instance via SSH with a .pem file that doesn’t have the appropriate linux filesystem permissions in place.

Recommended Fix:

CD to the directory where the file exists
Type : sudo chmod 400 <filename>

The next time you run ssh it should work.

Background:

I ran into this issue on a Macbook Pro running OS X. My file permissions were “too open” for use. The file permissions before I made the change were set to 0644 which threw the error.

Installation of Cisco UCS Platform Emulator on VMware Fusion - Mac OS X

June 30, 2015 by Nathaniel Avery

The Cisco UCS Platform emulator allows a person to simulate a complex Cisco UCS environment. The emulator is a great way to familiarize yourself with UCS Manager. Several examples of UCS PE installs exist online, but I found very few for Mac OS X users with VMware Fusion. These videos aim to rectify that.

Note - The videos are a little long as they are real time. The video is cut only in a few places for the sake of time.
