The Rock That Broke The Nazi Enigma

Her name was Margaret Rock, also known as one of Chief Cryptographer Dilly Knox’s “girls” in Cottage 3 at Bletchley Park, working alongside Mavis Lever.

In August 1940 Knox complained the sexist Civil Service grading system had misclassified Rock as a linguist or clerk rather than a cryptanalyst, which capped her pay regardless of what she actually did. It wasn’t just an advocacy for fair pay, it was also Knox saying the scare quoted “professors” are just fancy titles and grades for men who were not doing any better work than the women.

The top UK salary allowed because of her gender was £195pa. For context, a male senior cryptanalyst at Bletchley on the higher Civil Service grades would have been earning many times more than her in 1940. Rock was doing fourth or fifth best work on the Enigma staff yet capped far below what the men received.

Indeed, it was Rock who broke the Abwehr Enigma (variant G) with Knox and Lever on December 8, 1941. Rock and Lever had cracked the GGG indicator system in October, the precursor stage. Despite the significance of this feeding into the “Double Cross” system and the D-Day deception, and despite being awarded the MBE in 1945, Rock was never graded fairly in her lifetime. She left GCHQ in 1963. The UK Civil Service want you to know this about her:

She remained single throughout her life and lived in her later years with her longtime friend from North Middlesex School, Norah Sheward.

OpenAI is Firing People on All Cylinders

It’s pretty clear from the John Oliver reporting, about OpenAI driving people to suicide, that the company is definitely on the wrong side of history. But it’s a different set of “missed targets”, based on Wall Street, that generates headlines like this one:

OpenAI Hits Back at Growth Fears, Says ‘Firing On All Cylinders’

Oh, really? Are we supposed to relate to the lack of growth as a real fear?

Like, were there not enough suicides already? Or, since they mention firing, were there not enough layoffs yet? OpenAI has been saying everyone will lose their jobs so, that must be the growth they “hit back” on.

Firing people, on all cylinders. Ok, then.

OpenAI is saying they are all about growth in something, without really acknowledging that lying and mass harms are what it has become most known for growing.

CA Tesla Kills One in “Veered” Crash Off Highway

The facts reported from this crash so far point to a sleeping young driver, fatally allowing “driverless” to veer off a major Highway.

An 18-year-old driver from Thousand Oaks died in a crash on southbound Highway 101 outside Ventura April 26.

The California Highway Patrol said it responded to reports of a car going off the roadway south of Seacliff shortly before 9 a.m. Officers said they found a gray Tesla car on the right shoulder with an unresponsive driver, CHP officials said in a news release.

In its preliminary investigation, the CHP said the driver apparently let the car drift to the right where it struck a metal guardrail and went over the side of the highway. The driver suffered major injuries and was pronounced dead at the scene, CHP said.

Officer Christian Givens said April 27 that the driver veered from the No. 1 lane in the center of the highway all the way to the right.

Notably, this reads to me as a physical guardrail failed to stop AI from killing a human.

SC Tesla Kills One in “Veered” Crash Into Pole

Tesla is a decade into their promise to deliver driverless as a safety device, and yet it still seems to increase the chances of a sudden unexplained death.

One person is dead after a crash in Colleton County Saturday night.

The South Carolina Highway Patrol said the crash happened just before 11:30 p.m. on Highway 21 near Fireman Lane.

The driver of a 2026 Tesla sedan was going south on Highway 21 when they drove off the right side of the road, according to Cpl Nick Pye. The driver then hit a curb, a utility pole and a fence before the car overturned.

A decade of deaths just like this and no resolution in sight? A 2026 model? Tesla has only just begun to admit their hardware design was also flawed from the start, beyond recurring obvious deadly software failures.

There are millions of Tesla vehicles on the road today which were sold on the promise of full autonomy, but without hardware capable of doing so.

Incapable. Read that as a death-wish to those who believed the lies. The fact that 2026 models still exhibit the “veered” death pattern, suggests the big upgrade effort still won’t achieve the most basic expected capabilities.
