The title is misleading, they have most likely only been dead for a few months since their bodies were found still decomposing.

You can take screenshots by plugging a usb stick into the scope

Most computers have an Embedded Controller (with integrated flash) that does a lot of motherboard/system specific stuff like power management, flashing leds and even scanning the keyboard matrix on laptops.

Smallest feature size no longer correlates with transistor density in recent years. So manufacturers just use the number to convey increases in transistor density.

That one has an i7-5557U, compared to the i7-6500U the current one is selling with, so probably an early prototype.

They say on their website "Atheros 802.11n w/ Two Antenna"
Wi-fi cards are actually a huge issue if you are concerned about privacy. You have no idea what the firmware is doing, and it has access to your entire memory through the pcie interface, and the internet at the same time.

> not going to the local police station whenever you stayed at a hotel/switched apartment/stayed at your friends/partners place
I've never heard of this and I grew up in China. Can you provide a source?

Cortex M cores don't have MMUs, so they cannot be affected. Also in embedded applications you would only be running trusted code anyway

It seems like the domain expired, and now it redirects to a gambling site.

I modified a kernel module to use the wifi enable/disable button on my hp laptop as a normal button. For some reason the bios sends an acpi event when the button is pressed, instead of just having it as a normal keyboard key, so there is a kernel driver to handle it.

Nuclear reactors need to be built next to a large body of water for cooling. So Japan didn't have a choice when they wanted to have nuclear power.

I'm also a 17 year old. I always say just have fun. So really, just do whatever you want and whatever makes you happy. Unless money is a big concern for you, you shouldn't go work in paying job. It's much less stressful when you are just messing around, instead of meeting someone else's deadline.
Also some of the comments here suggest socializing. Personally I'm not a very social person, when I get home from school I really just want to be left alone. I just want to say that if socializing is your thing, then go for it, but if it's not, don't feel that you are being pressured into it.
