Completed a course at BCIT: Relational Database and SQL

Back in December 2011, I just completed a 12-week evening course COMP 1630 at BCIT in downtown Vancouver. This was a great course worth 5 credits, and delved into database design, architecture, a little systems analysis, and a lot of SQL syntax. We learned about Crow’s Foot Notation in building an initial requirements design before translating that into actual tables, columns, indices, contraints, etc. It helped strengthen what I already knew of database systems and look forward to taking database administrator-type courses this year.

MacBook Pro boots up showing a folder with a flashing question mark

This dreaded flashing question mark inside a folder means that the startup disk is no longer able to find a Mac operating system to boot from. There are a few things you can try to do to fix this yourself. Reboot MacBook pro and then hold the Command (⌘) and R keys on your keyboard to startup from the macOS Recovery. I did this and was able to go through disk diagnostics telling me that there were some disk errors. I proceeded to fix what I could but found that on subsequent reboots to macOS Recovery showed different partition errors. Sometimes the disk utility completed successfully but other times it would stop repairing even if left overnight. If you did have a failing disk drive, the marked errors would be consistent and multiple passes will bypass these marked errors. I had erratic results however which led me to believe it may or may not be a bad disk. The next investigation should be to look at the disk drive connections to the SATA controller.

Unable to get to computer BIOS because monitor goes to sleep at startup?

I just enrolled in a course that requires running virtual machines on my Windows 10 Pro computer using VirtualBox. I couldn't start the virtual machines because of this error "The native API dll was not found (C:\WINDOWS\system32\WinHvPlatform.dll)". After doing some troubleshooting, I found this to mean that the hardware acceleration settings required by the CPU to support virtualization are currently disabled in my computer BIOS. I had to enable virtualization on my CPU chipset (VT-x/AMD-V). Seems easy enough, right? I rebooted my computer and was expecting to see the memory counter and options to get into the BIOS. It must have been so quick that it took me straight to Windows 10 login prompt right away. I tried again and as usual I am immediately back to Windows 10 login. Each time I reboot, there is a box that says my monitor is going to sleep and does not wake again until presented with Windows 10 login prompt. I can hear the disk and fans spinning during startup,

Troubleshooting Microphone Problems using Fortnite on PS4

My son has been playing the popular game called Fortnite www.epicgames.com/fortnite/ on PlayStation 4 for many months now. There is social component to the game where a team of players collaborate by using their headset and microphone in their party/group chats. One day, the microphone on my son’s headset stopped working in Fortnite. The troubleshooting that father-son had to go through to fix the issue is worth blogging about because I couldn’t stand seeing him get declined from Battle Royale party invites and just playing the game solo which isn’t as fun. For a few days, he would FaceTime his friends on our iPad so that they can talk on the side while playing Fortnite on PS4. You probably won’t want to go through that scene as well so I thought it’s time to put in some of the troubleshooting skills that we are so good at and put that to good use so that others can benefit from our experience. Here are 4 phases you will likely go through to try and fix this. 1) The first thing that
