¿Cúal fue el primer lenguaje de programación?

Pagina de Luis Alejandro Guzman Busso

En 1946 Grace Hopper, cientifica en sistemas y oficial de la marina estadounidense creo el FLOW-MATIC, considerado el primer lenguage de computadora útil para resolver problemas de usuarios comerciales, especificamente para la computadora UNIVAC 1. Era ligeramente cercano al idioma inglés y visto como un lenguaje de ‘alto nivel’: fácil de usar por los programadores pero necesitaba ser traducido por otro programa (compilador) en un lenguaje que la computadora pudiera interpretar y llevar a cabo.

En 1957 la compañia IBM creó FORTRAN, lenguaje diseñado especificamente para uso científico. Su nombre proviene del ingles Formula-Translator, o traductor de fórmulas. Éste se convirtio en el primer lenguaje de programación de alto nivel para programadores disponible para programadores de espectro mas alto.

En 1958 surgió una versión mejorada llamada ALGOL (Algoritihmic Laguaje) y despues COBOL (Command Business Oriented Languaje); este ultimo se empleaba para organizar archivos y administrar bases de datos de negocios.

Learning Emacs – part 1: Introduction, entering emacs, and exiting emacs

Blasphemous Bits

So I’ve decided to learn Emacs. I’ve always been more of a Vi man previously, and I still consider some moderate amount of comfort with Vi to be a necessity for any Unix sysadmin. I’ve also used a few of the major IDE’s for programming: I use Eclipse with RadRails for all of my Ruby development, a friend who’s trying to get me to learn Java has introduced me to NetBeans, and I’ve played a bit with C# in Visual Studio.

So why learn Emacs? Well, there are a so many people on the net who swear by Emacs, including some who otherwise seem to be very sensible and non-masochistic. 🙂 It’s also supposed to be the environment of choice for Lisp and Scheme programming, which is something I’d like to learn more about. So, operating under the principle that “where there’s smoke there may be fire”, I’m going to…

Donald Trump

Fevered media speculation about Donald Trump’s psychological motivations and psychiatric diagnosis has recently encouraged mental health professionals to disregard the usual ethical constraints against diagnosing public figures at a distance. They have sponsored several petitions and a Feb. 14 letter to The New York Times suggesting that Mr. Trump is incapable, on psychiatric grounds, of serving as president.

Most amateur diagnosticians have mislabeled President Trump with the diagnosis of narcissistic personality disorder. I wrote the criteria that define this disorder, and Mr. Trump doesn’t meet them. He may be a world-class narcissist, but this doesn’t make him mentally ill, because he does not suffer from the distress and impairment required to diagnose mental disorder.

Mr. Trump causes severe distress rather than experiencing it and has been richly rewarded, rather than punished, for his grandiosity, self-absorption and lack of empathy. It is a stigmatizing insult to the mentally ill (who are mostly well behaved and well meaning) to be lumped with Mr. Trump (who is neither).

Bad behavior is rarely a sign of mental illness, and the mentally ill behave badly only rarely. Psychiatric name-calling is a misguided way of countering Mr. Trump’s attack on democracy. He can, and should, be appropriately denounced for his ignorance, incompetence, impulsivity and pursuit of dictatorial powers.

His psychological motivations are too obvious to be interesting, and analyzing them will not halt his headlong power grab. The antidote to a dystopic Trumpean dark age is political, not psychological.

Lots And Lots Of foldLeft Examples

Matt Malone's Old-Fashioned Software Development Blog

In my last post I reviewed the implementation of scala.List’s foldLeft and foldRight methods. That post included a couple of simple examples, but today I’d like to give you a whole lot more. The foldLeft method is extremely versatile. It can do thousands of jobs. Of course, it’s not the best tool for EVERY job, but when working on a list problem it’s a good idea to stop and think, “Should I be using foldLeft?”

Below, I’ll present a list of problem descriptions and solutions. I thought about listing all the problems first, and then the solutions, so the reader could work on his own solution and then scroll down to compare. But this would be very annoying for those who refuse, against my strenuous urging, to start up a Scala interpreter and try to write their own solution to each problem before reading my solution.

Last week Donald Trump told the US Army Corps of Engineers to stop their comprehensive environmental review of the Dakota Access Pipeline. It’s up to us to deny that request. Sorry, Donald.

Yesterday, things got worse. This review moved one step closer to being scrapped as the Acting Secretary of the Army Corps directed them to grant the final permit needed. It could happen any time now and construction could resume – unless we flood the Army Corps with comments telling them to continue their full environmental review of the pipeline.

If we succeed, DAPL will be forced through a multi-month review of its impact on drinking water, tribal rights and the climate. The only way to approve this pipeline without conducting the review would be to to disregard the hundreds of thousands of comments from people like you.

Join the resistance: send a comment to the Army Corps of Engineers demanding a comprehensive environmental review of the Dakota Access Pipeline.

The Standing Rock Sioux tribe, whose drinking water and sacred sites have been desecrated by this pipeline, already announced plans to sue to stop any action to expedite DAPL. Every comment we send bolsters their legal case that the federal government would be abandoning their own rules and procedures by illegally forcing the project through.

Not only is Trump’s administration full of Big Oil cronies, he also owns stock in the company behind Dakota Access. Illegally forcing this project through is an obvious example of corruption — not to mention a gross violation of Indigenous rights and the science of climate action.

To be honest, he’s holding a lot of the cards in this fight. But he’s also facing some of the most dedicated and most effective grassroots organizers in North America — the indigenous leaders who brought over 500 tribes together in this historic fight, the hundreds and thousands of people who stood out in the cold in North Dakota with them, not to mention the millions of people supporting this fight around the country, and the rest of the world — and I will never rule them out.

It’s our job to have their backs, and we can do that by flooding the Army Corps with comments against DAPL and fighting Trump’s plan to fast track this pipeline.

If the first 10 days of Trump’s administration have shown us anything, it’s that people are ready to resist in unheard of numbers. Let’s keep the pressure on.
