Udemy – The Complete Oracle SQL Certification Course

link:: https://www.udemy.com/the-complete-oracle-sql-certification-course

This course is lead by instructor Imtiaz Ahmad, a Senior Software Engineer by trade and enthusiastic trainer @ Job Ready Programmer. I stress his credentials because the truth is anyone can teach programming, I could spin up a course right now on Udemy by doing nothing but copying a book that I like, trimming it down and reading the lines. That is not a course, that would be a dictation, and frankly a waste of my time.

What I look for in a course is an instructor whose been out in the flames for a while, gotten burnt, learned his lesson and can now teach me things to look out for. I think the best teachers do this almost instinctively, they’re wisest words seem to come as offhand remarks, quick references, or unintentional tangents peppered throughout the course. These moments where you tear away the veil of student – teacher – computer screen, and you see yourself applying the course in real life. That’s where I get my money’s worth, that is the gold nugget that short of having an apprenticeship I won’t get anywhere else. Imtiaz brings this real life knowledge to you in this course, showing you how you might see things written in the real world, variations in the use of SQL, and how you should write it to best utilize Oracle 12G.

Don’t Smash That SD Card!

Stop! Wait! I know what you’re thinking. This SD card has more the 50MB on it, but Windows won’t format it properly. Even Disk Management is failing.

For anyone who backs up their Raspberry Pi images or re-images their SD cards, this can be a huge hassle. Let alone if that unfortunate moment has come and your SD card or USB stick is showing no memory available at all. The formatting is just ruined. Breathe deep there are utilities out there to help.

Fedora 24+ Remote Desktop (VNC)

One issue I’ve found written about on forums (without resolution) and experienced with much frustration is getting remote desktop via VNC to work on Fedora 24 server and newer. It seems like something has changed in the matrix and running the standard setup for vnc server on Fedora that worked on Fedora 19/20/21/22/23.. just doesn’t seem to work. Now as curious as I am, I’m not going to go install a VM of any of those versions of Fedora and track down the minutia of differences. What I will describe though is how to get it to work.

If you’ve been trying this and can’t seem to get it to work, the problem may lie on the TigerVNC viewer for Windows. For me the Windows VNC client keeps connecting properly but the screen is always blank. I noticed the vncserver instances that I started on my Fedora server were all 24 bit and the Windows TigerVNC viewer kept “connecting” to 32 bit sessions. What did work for me was switching to RealVNC viewer, the connection worked perfectly on my local server.

The step by step instructions are as follows:
