Where 295 fits
Why 295 is special
Disabling certificate checks to make development work, and then shipping that, is the single most common way TLS is made decorative.

Roman numerals
C C X C V
CCXCV uses the subtractive pair XC: ten before a hundred — a hundred minus ten.
Binary
1 0 0 1 0 0 1 1 1
1 × 256 + 0 × 128 + 0 × 64 + 1 × 32 + 0 × 16 + 0 × 8 + 1 × 4 + 1 × 2 + 1 × 1 = 295
Octal
4 4 7
4 × 64 + 4 × 8 + 7 × 1 = 295
Hexadecimal
1 2 7
1 × 256 + 2 × 16 + 7 × 1 = 295
Read as powers of two: 256 + 32 + 4 + 2 + 1 = 295.
In historical numeral systems
Egyptian
2 coils of rope, 9 hobbles, 5 strokes
2 × 100 + 9 × 10 + 5 × 1 = 295. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
4 vertical wedges (sixties place), 5 corner wedges + 5 vertical wedges (units place)
4 × 60 + 55 = 295. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
sigma, then koppa, then epsilon, marked as a numeral
sigma-koppa-epsilon + keraia
sigma + koppa + epsilon written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
resh, then tsadi, then he
resh-tsadi-he
resh (200) + tsadi (90) + he (5) = 295, written in descending order.
Maya
2 bars + 4 dots (upper, twenties place) over 3 bars (lower, units place)
14 × 20 + 15 = 295. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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.

Certificate validation is what makes an X.509 chain mean anything, and disabling it is the usual way TLS becomes decorative.

Technology & computing
CWE-295 covers failure to validate a certificate chain, hostname or expiry. Validation disabled during development and left in place is a recurring source of the weakness.

Common questions
Is 295 a prime number?
No, 295 is not prime.
What are the factors of 295?
The factors of 295 are 1, 5, 59, 295.
What is 295 in Roman numerals?
295 in Roman numerals is CCXCV. XC is subtractive: ten before a hundred — a hundred minus ten. Written additively it would be CCLXXXXV, which Roman inscriptions used freely — the strict subtractive form is a later convention.
