My first computer was a Radio Shack Color Computer 3 - 6809-based, running OS-9 Level II. It could run 32 processes at once, due to bank-switching a whole 1 Meg of memory.

After that, I got an AT&T 3b2, also known as a Convergent Safari. This was a Motorola 68010-based desktop.

Then, I graduated to a NeXT black&white "slab". I bought a used SPARCStation IPC in 1995, and put NetBSD 0.9 on it. I ran NetBSD on the IPC and a SPARCStation 10 until 2002.

I've been using Linux since 1997, starting with a DEC Alpha-based UDB, and downgrading to a x86 PC in 2002.

I run Arch linux, on my server and my laptop.

comment /proc/self/maps - 3rd mapped piece of file?
@Gilles - if you do readelf -h /usr/bin/cat, you can see that the .text and .rodata sections end up in the first LOAD segment. .data and .bss sections end up in the second LOAD segment. This 3rd mapped segment is something else.

comment Arch ntpd/ntpdate not synchronizng clock
This looks a little bit like a DNS problem, perhaps slow response, specifically the "Host name not found" lines. I just stopped and restarted ntpd on my arch linux server, and I didn't see those lines. What's available on raspi to debug DNS problems? Also, it probably doesn't matter, but why the "iburst" option? Seems a little weird to do that without a specific reason.

comment Why does a disk clone using dd take up more space on the target than the source image?
@Andrew - you make a good point. Sorry, I seem to have mis-read your question. I had to re-read it three times to understand your comment. Sorry for the potential mis-directrion.

comment Linux Kernel logical address space organisation
@sdaau - The arguments ac and av and automatic variable local will probably have different addresses on each invocation. Most modern Linux kernels have "Address Space Layout Randomization" to make exploiting buffer overflows harder.

comment Why is dd using direct slower writing to disk than to a file
@user3216949 - I think that's true, but I don't have direct knowledge. The block device is at the end of the user -> kernel -> file system -> disk drive layers. As I understand it, using the block device eliminates the file system layer(s) in the stack.
