Underscores do not work inside a word (so my_long_identifier won’t accidentally become mylongidentifier, but _foo_ will become foo)

Essentially, IPv4 addresses[2] are just numbers from 1 to 2147483647, for example 3405804031. However, since address routing is often based on common binary prefix, more intuitive methods like 203.0.113.255 are used. This notation is just a length-4 list of integers from 0 to 255. To convert from an integer to a common IP address, you divide-with-remainder with a constant divisor of 256. For example, 3405804031 /% 256 = (13303921,256), 13303921 /% 256 = (51968,113), 51968 /% 256 = (203,0), and 203 /% 256 = (0,203).[1] Collecting all the remainders in reverse order, then joining them with periods, produces 203.0.113.255. (This notation is just for people to read; aside from parsing code, none of IPv4 uses this notation.) When you enter an IPv4 address, the opposite happens — an expression like ((203 * 256 + 0) * 256 + 113) * 256 + 255, which evaluates to 3405804031, is performed. These octets are just numbers — using 203.000.113.255 or 203.00.113.255 in place of 203.0.113.255 is merely a choice of how to write the address, as 203 * 256 + 0 = 203 * 256 + 000. mraow
[1]: this operation can be omitted; I include it for symmetry. [2]: though all of this holds true for IPv6, I really didn’t feel like going through 128 bits of address

Many services including Gmail silently ignore periods in localparts, so foo.bar and foobar are the same address.
overall we need something to text
pretty much Matrix’s entire point
(plus send files)
also implemented in pretty much every server and client; I think even Element can send files
call
look into e.g. #matrixrtc:continuwuity.org — sable requires a setting to show the call button in non-DM rooms
video/screen share
unfortunately this is the only thing I’m not confident is supported
bonus for emojis, stickers
should be available with any im.ponies-compatible client such as sable
Not telemetry? Continuwuity just uses it to post release announcements to the admin room; I think there’s a way to disable it if you prefer.
Thanks; didn’t have it saved like that
There’s already Windows S mode — if you bought a device with S mode enabled, you need a Microsoft account to disable it.
