What an RAF pilot can teach us about being safe on the road

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

“Sorry mate, I didn’t see you”. Is a catchphrase used by drivers up and down the country. Is this a driver being careless and dangerous or did the driver genuinely not see you?

According to a report by John Sullivan of the RAF, the answer may have important repercussions for the way we train drivers and how as cyclists we stay safe on the roads.

John Sullivan is a Royal Air Force pilot with over 4,000 flight hours in his career, and a keen cyclist. He is a crash investigator and has contributed to multiple reports. Fighter pilots have to cope with speeds of over 1000 mph. Any crashes are closely analysed to extract lessons that can be of use…

A Story of Slavery in Modern America

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

The ashes filled a black plastic box about the size of a toaster. It weighed three and a half pounds. I put it in a canvas tote bag and packed it in my suitcase this past July for the transpacific flight to Manila. From there I would travel by car to a rural village. When I arrived, I would hand over all that was left of the woman who had spent 56 years as a slave in my family’s household.

Her name was Eudocia Tomas Pulido. We called her Lola. She was 4 foot 11, with mocha-brown skin and almond eyes that I can still see looking into mine—my first memory. She was 18 years old when my grandfather gave her to my mother as a gift, and when my family moved to the United States, we brought her with us…

What Happens When You Mix Java with a 1960 IBM Mainframe

IBM Mainframe

As an engineer for the U.S. Digital ServiceMarianne Bellotti has encountered vintage mainframes that are still being used in production — sometimes even powering web apps. Last month she entertained a San Francisco audience with tales about some of them, in a talk called “7074 says Hello World,” at Joyent’s “Systems We Love” conference.

Created under the Obama administration, The U.S. Digital Service was designed as a start-up-styled consultancy to help government agencies modernize their IT operations, drawing engineering talent from Google, Facebook and other web-scale companies.

Or, as President Obama put it last March, it’s “a SWAT team — a world-class technology office.”

So it was fascinating to hear Bellotti tell stories about some of the older gear still running, and the sometimes unusual ways it was paired with more contemporary technology…

Rails is f*cking boring! I love it.

Together with a friend I recently built Dropshare Cloud. We offer online storage for the file and screenshot sharing app Dropshare for macOS/iOS. After trying out Django for getting started (we both had some experience using Django) I decided to rewrite the codebase in Rails. My past experience developing in Rails made the process quick — and boring…

A Russian Slot Machine Hack Is Costing Casinos Big Time

Slot machine.

In early June 2014, accountants at the Lumiere Place Casino in St. Louis noticed that several of their slot machines had—just for a couple of days—gone haywire. The government-approved software that powers such machines gives the house a fixed mathematical edge, so that casinos can be certain of how much they’ll earn over the long haul—say, 7.129 cents for every dollar played. But on June 2 and 3, a number of Lumiere’s machines had spit out far more money than they’d consumed, despite not awarding any major jackpots, an aberration known in industry parlance as a negative hold. Since code isn’t prone to sudden fits of madness, the only plausible explanation was that someone was cheating…

Defeating Quantum Algorithms with Hash Functions

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

In this post I’ll explain why quantum computers are useless to find hash function collisions, and how we can leverage this powerlessness to build post-quantum signature schemes. I’ll then describe a quantum computing model that you can try at home, and  one where hash function collisions are easy to find…

TLS 1.3 FTW

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

In common slang, FTW is an acronym “for the win” and while that’s appropriate here, I think a better expansion is “for the world.”

We’re pleased to announce that we have sponsored the development of TLS 1.3 in OpenSSL. As it is one of the most widely-used TLS libraries, it is a good investment for the overall health and security of the Internet, so that everyone is able to deploy TLS 1.3 as soon as possible…

A Constructive Look At TempleOS

This is a repost promoting content originally published elsewhere. See more things Dan's reposted.

TempleOS is somewhat of a legend in the operating system community. Its sole author, Terry A. Davis, has spent the past 12 years attempting to create a new operating from scratch. Terry explains that God has instructed him to construct a temple, a 640×480 covenant of perfection. Unfortunately Terry also suffers from schizophrenia, and has a tendency to appear on various programming forums with a burst of strange, paranoid, and often racist comments. He is frequently banned from most forums
