The Bletchley Park codebreakers depicted in the film The Imitation Game (this year’s Oscar winner for Best Adapted Screenplay) worked around the clock to crack the secret of Nazi communications during World War II, but they weren’t all about work. They also used their skills for play.
Mark Saltveit, World Palindrome Champion and editor of The Palindromist Magazine, has spent years researching palindrome history and recently published an article on Vocabulary.com where he shares his discovery that many well-known palindromes originated from a bit of spirited competition among the cryptanalysts of Bletchley Park.
It started with mathematician J.H.C. Whitehead’s* “Step on no pets,” which was answered by Peter Hilton’s “Sex at noon taxes,” and ended, after many rounds of increasingly heated one-upmanship with “what many consider the best palindrome ever.” No, not the Panama one, amateurs. This one:
Doc, note: I dissent. A fast never prevents a fatness. I diet on cod.
The palindrome first came to light when it was the winner of a 1967 magazine contest. The person who submitted it admitted that he had not composed it himself, but had heard it from someone else who had also not composed it. Saltveit has now traced it back to Peter Hilton, the young mathematician who in the film pleads to use information from their partial decryption to save his brother on a naval convoy that is about to be attacked. (That did not happen in real life. Hilton did not have a brother on a naval convoy.)
It makes sense that those with a talent for uncovering meaning from patterns in strings of symbols would have a knack for creating palindromes. After all, a palindrome is just a meaningful string of symbols constrained by a specific type of pattern. In particular, Hilton’s talent for visualizing two streams of information at once came in handy. He composed the champion palindrome in his head, without writing anything down, over the course of five hours, while lying in bed with his eyes closed.

A prefeitura da metrópole argumenta com estatísticas: o uso de bicicletas na cidade cresceu 10% no último trimestre e bateu seu recorde. Elas já são 16% do tráfego de veículos no centro da cidade. É preciso fazer mais ciclovias e estações de aluguel.
Não, não é o paulistano Fernando Haddad. É seu colega londrino, que investe R$ 4 bilhões para melhorar a infraestrutura cicloviária de Londres e aumentar a segurança dos ciclistas. Fora do Brasil, o transporte a pedal não é uma mesquinha questão partidária. É uma imposição econômica.
Todo ano, o mundo produz mais de 130 milhões de bicicletas - o dobro do que fabrica de carros. E essa diferença continua crescendo, entre outros motivos, porque uma invenção centenária está, enfim, seduzindo o mercado: a e-bike.
A bicicleta motorizada existe desde o fim do século 19, mas apenas nos últimos anos a tecnologia evoluiu ao ponto de popularizar a produção de motores elétricos realmente eficientes e de baterias leves, recarregáveis e duradouras. Tudo isso combinado a sensores que captam o movimento e a força da pedalada e transferem para a roda a energia que faltava. O resultado é uma bicicleta que aplaina qualquer cidade.
After more than two years of discussion, over 200 design issues, 17 drafts, and 30 implementations, the HTTP/2 and HPACK specifications have now been approved by the IETF’s steering group for publication as standards-track RFCs. The result is that HTTP/2 will help provide faster user experience for browsing, reduce the amount of bandwidth required, and make the use of secure connections easier.
The HTTP Working Group began work on HTTP/2 in 2012 by selecting Google’s SPDY protocol as the starting point, holding a series of six interim meetings to incorporate community feedback. This resulted in substantial changes to the format of the protocol, its compression scheme, and its mapping to the semantics of HTTP.
The resulting protocol is designed to allow a seamless switch between HTTP/1 and HTTP/2, with minimal changes to applications and APIs, while at the same time offering improved performance and better use of network resources. Web users largely will be able to benefit from the improvements offered by HTTP/2 without having to do anything different.
A key point in the protocol development process was the iteration the working group did between protocol updates, and implementations and testing. Certain draft protocol versions were labelled by the working group as “implementation drafts”, and the participants — many web browser and web server providers — updated their implementations and tested out the protocol changes. Most of the interim meetings included part of a day spent on hands-on interoperability testing and discussion. The result is a thoroughly validated protocol that has been shown to interoperate and that meets the needs of many major stakeholders.
The HTTP/2 work specifically embodies the key IETF tenet about the value of “rough consensus and running code.”

Recently a random troll online asked me “what era do you think you’re living in?” when I posted about white violence and racism.
The fact that of all the evidence, of all the violent murders, that the one with the clearest, most undeniable evidence (oh but all of them are already past the point of reasonable burdens of proof, as well), of a man being choked to death, for supposedly selling cigarettes illegally, that people are anry and upset at what is clearly an extrajudicial murder, is “offensive” - on the cast of a movie that is all about white violence and extra judicial murders?
It is not just the murderers, it is the multitudes who will excuse and protect them - that is the danger. MLK wrote about the White Moderate who will stand by and protect the murderers, to tell everyone “wait, just a bit longer” while they are murdered in the streets.
That is the decade I live in, and the the decade we all live in, still.

...Meanwhile, I propose a new social norm. My strong suspicion is that we'd all be better off if Americans developed a broad aversion to people being fired for public missteps that have nothing to do with their jobs. That norm would do more good than bad even if you think some people deserve to be fired. Sure, I'd advise against taking flip photographs at a military cemetery. But whatever one thinks of that error in judgment, there's no reason it should cause a woman to lose her job helping developmentally disabled adults.An insensitive Halloween costume may justify a dirty look or scolding or even shaming. It should not deprive someone of their livelihood! It's strange when you think about it, this notion of getting sacked as a general purpose punishment that an angry faction of the public demands of an at-first-reluctant employer. The target, the mob demands, should have to find a new job, or go on welfare, or move back in with their mom, or perhaps starve. It's not even clear what's meant to happen. Let's rethink this.People should usually feel ashamed of themselves for thinking, "I should get that stranger fired." Companies should be left alone when one of their employees does something offensive while "off-duty." Since some Internet trolls will break that rule, here's another: Companies should expect to get more criticism for caving to the demands of trolls than for letting a briefly unpopular employee keep performing his or her duties, even amid an episode of obsessive public shaming. After all, these things always blow over, the attention span of the Internet being short, while losing one's job is, for many, a setback with consequences that last years. And have any of these firings achieved any social good? I defy anyone to produce hard evidence to that effect.Here's what corporations should say in the future: "Sorry, we have a general policy against firing people based on social media campaigns. We're against digital mobs."But note the one exception built into what I propose. Sometimes people do stupid things in the public eye that relate directly to their jobs. If, say, a DEA agent writes a Facebook post bragging about how many innocent black people he's going to lock up for drug trafficking next month, then it's obviously legitimate to demand his immediate termination. But generally speaking, Americans ought to be averse to the notion of companies policing the speech and thoughts of employees when they're not on the job. Instead, many are zealously demanding that companies police their workers more, as if failing to fire someone condones their bad behavior outside work. Few general standards work out best in every last circumstance. But the one I suggest would be better than what we've got.
