La primera hoja de cálculo para PCs cumple 35 años

En la primavera de 1978 mientras que Dan Bricklin se sentaba en una de las clases del Máster que se estaba sacando en la Escuela de Empresariales de Harvard (Harvard Business School), se le ocurrió la idea de plasmar de forma electrónica lo que el profesor estaba haciendo en la pizarra. Éste, estaba dibujando una matriz con números en ciertas celdas y operaciones aritméticas en ciertas otras. Es decir, a Bricklin se le acababa de ocurrir la idea de crear una hoja de cálculo electrónica. ...

We are rate limiting the FCC to dialup modem speeds until they pay us for bandwidth

Since the FCC seems to have no problem with this idea, I’ve (through correspondence) gotten access to the FCC’s internal IP block, and throttled all connections from the FCC to 28.8kbps modem speeds on the Neocities.org front site, and I’m not removing it until the FCC pays us for the bandwidth they’ve been wasting instead of doing their jobs protecting us from the ”keep America’s internet slow and expensive forever” lobby. ...

ASCII Chart

The American Standard Code for Information Interchange (ASCII) was developed under the auspices of a committee of the American Standards Association, called the X3 committee, by its X3.2 (later X3L2) subcommittee, and later by that subcommittee’s X3.2.4 working group. The ASA became the United States of America Standards Institute or USASI and ultimately the American National Standards Institute. » Charles Torvalds | askapache.com

The Forgotten History Of CGI

The roots of CGI lie in the first mechanical aids to drawing and painting. The earliest of these were developed to help solve a problem every artist has found to be sticky: perspective. Before the introduction of geometric perspective, the realistic depiction of nature was not one of the purposes of art. Instead, artists chose the size and position of objects in a picture by their relative importance to one another. A distant castle might appear to be larger than one in the foreground simply because it was considered more important. ...

The Golden Age of Basic

I remember my first program, by which I mean one that I cobbled together myself, not simply typing in a complete listing from the manual. I was twelve, the year was 1985, and the computer a Texas Instruments TI-99/4A (a machine which was actually the first 16-bit home computer). My program was a very simple text adventure game, created by chaining together as many IF¦ THEN GOTO statements as I had patience for. ...

Programming Sucks

Every friend I have with a job that involves picking up something heavier than a laptop more than twice a week eventually finds a way to slip something like this into conversation: ”Bro,1 you don’t work hard. I just worked a 4700-hour week digging a tunnel under Mordor with a screwdriver.” They have a point. Mordor sucks, and it’s certainly more physically taxing to dig a tunnel than poke at a keyboard unless you’re an ant. But, for the sake of the argument, can we agree that stress and insanity are bad things? Awesome. Welcome to programming. ...

Programming is social

Programming is social, too. Most people think it’s not. With assistance from media portrayals of programmers and sloppy stereotypes of our own, they think most of us would prefer to work alone in the dark. Some do, of course, but even then most programmers I know like to talk shop with other programmers all the time. They like to talk about the places where they are stuck, as well as the places they used to be stuck. War stories are the currency of the programmer community. ...

Unsafe cookies leave WordPress accounts open to hijacking, 2-factor bypass

Yan Zhu, a staff technologist at the Electronic Frontier Foundation, came to that determination after noticing that WordPress servers send a key browser cookie in plain text, rather than encrypting it, as long mandated by widely accepted security practices. The cookie, which carries the tag ”wordpress_logged_in,” is set once an end user has entered a valid WordPress user name and password. It’s the website equivalent of a plastic bracelets used by nightclubs. Once a browser presents the cookie, WordPress servers will usher the user behind a velvet rope to highly privileged sections that reveal private messages, update some user settings, publish blog posts, and more. The move by WordPress engineers to allow the cookie to be transmitted unencrypted makes them susceptible to interception in many cases. ...
