Interesting.
The TLS layer is actually a negotiation process. Could you check your Firefox settings for me?
Type: about:config
What do you see in the 'security.tls.version.min field?
What operating system are you on? Also what version of FireFox?
Is it highly unusual for both Microsoft IIS and latest version of Firefox to negotiate all the way down to a warning level. The next time you see that happen could you take note of the server listed at the bottom of the codeproject page?

It's going from bad to worse; it says:
This might void your warranty!
I took my chances so here goes:
security.tls.version.min;1
I am using:
Windows 10 Home Build 1709 OS Build 16299.431
Firefox 60.0.1

Hi,

I would recommend setting your TLS minimum above TLS 1.0 but ultimately it's your choice.

I can only think of a few things that would cause Microsoft Windows 10.16299.431 with Firefox 60.0.1 to connect to Microsoft IIS here at codeproject and negotiate all the way down to a warning level. None of them are good things.

Something strange must be going on with Mozilla. When I try to access CP using SeaMonkey the page load arrows just circle endlessly but the page won't load. If I paste the same link into Chrome it loads normally.

Doesn't Windows 10 Home allow changing the user interface language? Try going to Settings | Region and Language, and see if you have an option to "Add a Language".

That doesn't seem to work.

Human race just 0.01% of all life but has destroyed over 80% of wild mammals – study | Environment | The Guardian[^]
Forgetting the provocative headline (don't want this to turn into Soapbox material) some of the statistics in this study are staggering.
Quote: Bacteria are indeed a major life form – 13% of everything – but plants overshadow everything, representing 82% of all living matter. All other creatures, from insects to fungi, to fish and animals, make up just 5% of the world’s biomass.
Quote: Of all the mammals on Earth, 96% are livestock and humans, only 4% are wild mammals

How much memory does a 8 bit computer need?
Practical answer: As much as you can squeeze onto the circuit board. In the past that used to be much less than what you hoped for and also far less than the 64k the processor could address.
Simple answer: 64k minus ROM, Video memory and memory mapped I/O devices is what's left for RAM in the memory map. In this case that would be exactly 32k. Today you can have that in one IC for two bucks. No need for a memory board, just put it onto the processor board.
Traumatized answer: 4k is not very much, but all there was in the old computer. Since then I have put together a few computers and all of them got as much memory as I could afford, preferrably the maximum. That would be those 32k, right?
Wrong. It turned out that I could squeeze a little more onto a memory board: Circuit board Design[^]
That's a full little board and every pin of those ICs is used. It divides up the 32k area into two 16k areas and provides the logic to switch each of them between 256 memory pages.
Fully loaded, this board will give an 8 bit processor access to 2 x 256 x 16k memory (plus the 32k of the rest of the memory map). That's 8 Mb! I hope that will last a while.
Edit: I also found a way to integrate the page switching into the stack protocol for calling subroutines (plus mapping logical to physical pages). This way the code will not be aware that it's running in paged memory. I can call anything at any time and the code will not notice anything of the bank switching.

Nice one... Not that I ever remember that the 64k memory stopped me from doing things, but 8Mb sound fascinating...
Not sure however I have heard those numbers in my days of C64... Amiga 500 with its 512k was a dream...

I saw a Z80 S-100 CP/M system that was full to the brim with 64k memory boards, but I guess that was was done more recently.
Look at this magazine from 1980[^]. They have an article about those 'upcoming' 16 bit processors, 8086, Z8000 and 68000. They came to the conclusion that those processors are neat, but not for home use. They needed at least 128k, if not more and who could afford to go to the limit?

As I recall, the Z8000 went virtually unnoticed in comparison with those other two 16-bit processors. I also remember that many people called the 68000 a 32-bit CPU. Another amusing memory is buying my first PC that had an 8MHz 8088. Back then no one had heard of the word "overclocked."

That's because it was 32 bit internally (data-bus, command-set), and therefor was a small miracle of the time by being forwad-compatible with later itself...

Ahh, then my little 8 bit CPU actually is a 16 bit CPU. It has 16 general purpose registers, each also 16 bits wide.
This actually is cheating. What counts is how many data lines go to the bus, not what the CPU can do internally.

It is cheating only if there is nothing behind those 16 bit registers... In 68000 there was an instruction set that was designed to work with 32 bit addressing too (the idea was to create binary code that continues to work as the CPU evolves)...
It was designed to be the first step and with 68020 they hit it.

Yes, the 68010 68008 was analogous to the 8088 with a multiplexed data bus but the 68020 had true non-multiplexed, 32-bit data bus.

And don't overlook that any pre-68020 program would run perfectly fine on a 68020 (or later) - not in an emulation mode, but 100% as native programs. The 68020 added a few instructions, as we have seen dozens of times in other architectures as well, but the architeture of the 68K and 6010 was carried on.
It is a pity that the 68K series didn't win the CPU battles. The instruction set is so clean that is resembles a RISC, the addressing modes are logical, ... the x86 is a terrible mess, in comparison. (It is actually so messy that have not dared to look into the x64, from fear of finding a similar mess.)
I could make a long list of processors with fewer data or address lines than the width of the CPU registers and internal data paths. It is, actually, quite common. Logically, the MMS of the 386 handled 32 bit addesses, but if my memory is right, it had only 25 physical address lines, so it could handle at most 32 MByte physical RAM.
Some of the early 8-bit CPUs had only 8 address lines, yet addressed 64K: The most significant 8 bits where sent out first, and one clock cycle later, the least significant 8 bits followed on the same lines. I believe some (quasi) 16-bit CPUs used similar methods for transferring 16 bit data values over 8 data lines.
On the other hand: The machine on which I did my first serious programming was a 16-bit "mini" (cabinet size) with 25 address lines: Through a quite fancy memory management system for its time, it could juggle segments around for up to 64 simultaneous users (plus background / daemon processes). That didn't make it a 25 bit CPU. It even had hardware for 48 bit floating point arithmetic, operating on triplets of 16 bit words; that didn't make it a 48 bit CPU. (Funny detail: It had this special machine instruction to reduce by one and multiply by 3, MIX3, which was tailored to Fortran float arrays, indexed from 1 rather than 0. So this instruction converted from the "logical" array index to the value to be added to the array base address to find the array eleement.)
The 8080 had an 8 bit architecture. Some instructions allowed two registers to be paired, as if they were one 16 bit register, but this was limited to a subset of operations. 8086 had 16-bit data paths and 20 bit addresses (that didn't make it a 20 bit CPU!) - you could operate on register halves, such as AH and AL (Accumulator High and Low), but the special case was splitting them up, the normal was to treat them as 16 bit registers.

There were various variants of the 80386. The original version (later renamed 80386DX) was a full 32-bit processor, with a 32/32-bit data/address bus. The 80386SX used the same instruction set, but had a 16/24-bit data/address bus. Other variants had a 16/26-bit data/address bus. Lastly, there was a 486-compatible chipset that replaced an 80386DX/80387DX combination with a single chip that did most of the work, and an additional chip that provided the FERR signal and not much else.
