Leandra Becerra Lumbreras

Leandra Becerra Lumbreras ((claimed) August 31, 1887 - March 19, 2015)[2][3] was a purported Mexican revolutionary and supercentenarian who claimed to have been born August 31, 1887 which would have made her the longest living person in history.

Biography

Becerra claimed to have been born on August 31, 1887, to parents who were singers.[4][5] As The Daily Telegraph writes, this would have meant that "She was 27 when World War One erupted, 75 when John F. Kennedy was shot and over 100 when the Berlin Wall came down."[6]

From 1910 to 1917, Becerra claimed to have fought as a leader of the Adelitas in the Mexican Revolution. The Adelitas were a group of women who joined with their husbands in battle.[7] During the revolution, she was purportedly romantically involved with Margarito Maldonado, a revolutionary leader, who she said gave Becerra an old rifle that she still owned in 2014. Becerra recounted that Maldonado was "one of the great loves of her life."[8]

It has been reported that Becerra outlived her five children and several of her 20 grandchildren, but, as last reported, she still had 73 great-grandchildren and 55 great-great-grandchildren.[9][10]

Oldest living person

Becerra claimed to have lost her birth certificate in a move in 1974, meaning she could not conclusively prove her age.[11] Since she did not have her birth certificate, the Guinness World Records could not verify Becerra's claim and instead recognized Misao Okawa (1898-2015) as the world's oldest living person, and Jeanne Calment (1875-1997) as the longest-lived person in history.[12]

After her death on March 19, 2015, some media outlets reported that the Mexican government had confirmed that she was 127 at the time of her death,[13] but no officials have so far confirmed this.

A baptism record has been found of a Leandra Becerra Lumbreras of June 4, 1904.[14] This person was born in Joya de San Francisco, Bustamante, Tamaulipas, on March 13 of that year as the daughter of Calixto Becerra and Basilia Lumbreras and would have turned 111 six days before Becerra's death.[15] If this was her, however, she would've been six years old when the Mexican Revolution started.

gollark: <@151391317740486657> Do you know what "unsupported" means? PotatOS is not designed to be used this way.
gollark: Specifically, 22 bytes for the private key and 21 for the public key on ccecc.py and 25 and 32 on the actual ingame one.
gollark: <@!206233133228490752> Sorry to bother you, but keypairs generated by `ccecc.py` and the ECC library in use in potatOS appear to have different-length private and public keys, which is a problem.EDIT: okay, apparently it's because I've been accidentally using a *different* ECC thing from SMT or something, and it has these parameters instead:```---- Elliptic Curve Arithmetic---- About the Curve Itself-- Field Size: 192 bits-- Field Modulus (p): 65533 * 2^176 + 3-- Equation: x^2 + y^2 = 1 + 108 * x^2 * y^2-- Parameters: Edwards Curve with c = 1, and d = 108-- Curve Order (n): 4 * 1569203598118192102418711808268118358122924911136798015831-- Cofactor (h): 4-- Generator Order (q): 1569203598118192102418711808268118358122924911136798015831---- About the Curve's Security-- Current best attack security: 94.822 bits (Pollard's Rho)-- Rho Security: log2(0.884 * sqrt(q)) = 94.822-- Transfer Security? Yes: p ~= q; k > 20-- Field Discriminant Security? Yes: t = 67602300638727286331433024168; s = 2^2; |D| = 5134296629560551493299993292204775496868940529592107064435 > 2^100-- Rigidity? A little, the parameters are somewhat small.-- XZ/YZ Ladder Security? No: Single coordinate ladders are insecure, so they can't be used.-- Small Subgroup Security? Yes: Secret keys are calculated modulo 4q.-- Invalid Curve Security? Yes: Any point to be multiplied is checked beforehand.-- Invalid Curve Twist Security? No: The curve is not protected against single coordinate ladder attacks, so don't use them.-- Completeness? Yes: The curve is an Edwards Curve with non-square d and square a, so the curve is complete.-- Indistinguishability? No: The curve does not support indistinguishability maps.```so I might just have to ship *two* versions to keep compatibility with old signatures.
gollark: > 2. precompilation to lua bytecode and compressionThis was considered, but the furthest I went was having some programs compressed on disk.
gollark: > 1. multiple layers of sandboxing (a "system" layer that implements a few things, a "features" layer that implements most of potatOS's inter-sandboxing API and some features, a "process manager" layer which has inter-process separation and ways for processes to communicate, and a "BIOS" layer that implements features like PotatoBIOS)Seems impractical, although it probably *could* fix a lot of problems
