If I ask myself again, computer architecture in a nutshell, what will I get from a quick writeup?
Websites that claim they can GPS track cell phones and look up personal information records? Most of the time, they’re a joke.

Plumbing is a consistent quality problem in homes. Why is this? What is the specific quality problem involved? Suffice it to say, every home’s plumbing is different, and any plumbers who come to work on the plumbing in a home must be willing to learn the specifics of a particular home and understand how that particular home works. And this is where the quality problem comes in. Quite often, plumbers aren’t interested in learning the specifics in great detail, so that is how the quality problems emerge. Walls are cut through randomly, pipes replaced haphazardly, hot water valve limits not calibrated correctly. And it’s not just water plumbing, it also extends to telecommunications, and in some cases electrical.
Alas, in either case, it is often times the homeowner who is most responsible for having the greatest understanding of the specifics of their local system. And this is where many homeowners can falter.
SD cards from Amazon? They were selling fakes here!

This is the best article I could find about fake SD cards. So, for purchases off of Amazon? Make sure that it is shipped and sold from Amazon, not some other company, in order to mitigate the risk of fakes.

Wikipedia doesn’t have much information on the subject of counterfeits.

Again, this would always be interesting, but I must keep saying the same thing. It would be nice to have a single standard site for item history, but for the time being that is something we can’t rely on. Nevertheless, it is interesting to see the various attempts made by different people.

More house systems, in order of construction. Note the importance of the quality of each system. If the system is mentioned, than there is an associated quality metric.

Notes on natural ventilation and sick building syndrome. Sometimes it’s just a “syndrome” because it is not possible to pinpoint a particular cause.

So now I’m reading up on getting the ODROID-C2… and upon a revist to Raspberry Pi, I’ve found out there was a new model of Raspberry Pi with a lot of competitive features… Raspberry Pi Model 3B+. Almost all the missing features you could have longed for from the previous Raspberry Pi models.

Also intersting is that.nowadays Raspberry Pi has an official power supply. However, I wouldn’t recommend it simply due to its size, which means surely it must not be as efficient as the mass market smartphone power supplies.

So how to you setup network boot? You have to write a value to one-time programmable memory: Network boot is disabled by default. So once you enable it, you cannot disable it.

Back-side illuminated sensors? They have their advantages in that the active matrix is behind the photodiodes, but they have disadvantages too, such as cross-talk. Suffice it to say, the main advantages are greater when the pixels are smaller, otherwise the active matrix doesn’t reflect too much light away from the photodiodes with larger pixels. That being said, these kinds of sensors are a major boon to modern smartphones, but only used in some modern DSLR cameras.

Powering the ODROID-C2? Your options:
Use a USB-to-2.5mm lead adapter with your USB power supply.
Use a USB On-The-Go cable with your USB power supply.
Use a dedicated 2.5mm power supply.
Yes, the community and documentation on ODROID-C2 is not as strong. What this basically means is that you can’t just hand it to a bunch of non-technical people and expect them to get by like you would with a Raspberry Pi for education. However, if you are already well accompanied with the development platform (you learned from a Raspberry Pi Zero!), then it is definitely worth it for the performance boost compared to Raspberry Pi 3.
