8000
Port 8000 is a common alternative HTTP port for development.
Where 8000 fits
Why 8000 is special
Python's built-in web server, many application frameworks and countless tutorials default to 8000 for the same reason as 8080: it is memorable and does not require administrative privileges to bind.
Same number, different meanings
How 8000 is understood across different contexts — never implying one meaning because of another.
- Mathematics
Python's built-in web server, many application frameworks and countless tutorials default to 8000 for the same reason as 8080: it is memorable and does not require administrative privileges to bind.
- Technology & computing
Python's built-in server and a long list of frameworks default to 8000 for the same reasons as 8080 — memorable, and bindable without administrative rights. It is probably the first port number a large share of programmers ever typed deliberately.
- Geography
Fourteen peaks exceed 8,000 m, and above about that height the human body deteriorates faster than it can recover regardless of acclimatisation. The first person to climb all fourteen finished in 1986.

1 × 4,096 + f × 256 + 4 × 16 + 0 × 1 = 8,000
Read as powers of two: 4,096 + 2,048 + 1,024 + 512 + 256 + 64 = 8,000.

8 × 1,000 = 8,000. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
