More than 40 years ago in 1968 ... A team led by Nikolai Nikolaevich Konstantinov creates a mathematical model of the motion of the animal (cat). The BESM-4 machine, executing a written program for solving ordinary (in the mathematical sense of the word) differential equations, draws a cartoon "Kitty" containing even by modern standards an amazing animation of cat movements created by a computer.

VLC, the exceptional open-source media player that pretty much runs on everything, has been one of the first programs I install on a new computer or smartphone for years. It's simple, powerful and free—I couldn't ask for anything more. Well, except maybe not having it play host to a critical (See update below) security vulnerability Read the rest
The fourth incarnation of the wonderful Raspberry Pi is upon us. A faster quard-core CPU, up to 4GB of RAM, gigabit ethernet and dual HDMI outputs are the upgrades; there's USB-C too, but just for power. The CPU boost is a big deal, say early users, but dual-4k displays and 4x the RAM bring it squarely into the realm of everyday desktop computing. Still $35; the 4GB model is $55.
Seriously look at this. True Gigabit Ethernet speed on Raspberry Pi 4.

Adam Bradley and Chris Blackburn noticed an unusual, mislabeled eBay listing for a rare beauty: an IBM System/360 in Nuremberg for peanuts. So they set out to do what any self-respecting IBM System/360 fan would do: buy it and fix it up. Thousands of Euros later, they've ... well, they've gotten it out of the building.
Read the rest... a once in a lifetime find. We decided we had to have it. Adam put in a bid of around 500 Euros and we waited. The advert finished the following day around midday. Luckily, Chris and Adam work together and as such the next morning in the office was rather tense! There was quite a flurry of bidding activity right at the end of the auction and with seconds to go and an exclamation of “Screw it!” Adam entered a bid of 4500 Euros. The hammer fell on 3710 Euros! We were now the proud owners of one IBM 360… or so we thought!
This is pioneering computer scientist and US Navy read admiral Grace Hopper (1906-1992) explaining the concept of a nanosecond. From the Computer History Museum:
(Hopper) held a B.S. in mathematics and physics from Vassar College (1928) and an M.S. (1930) and Ph.D in mathematics (1934) from Yale University.
Hopper began her career teaching at Vassar and taught there from 1931 to 1943, when she joined the u.s. Navy Reserve. Her first assignment was to work with Professor Howard Aiken of the Harvard Computation Laboratory on problems of military significance.
Hopper remained at Harvard until 1949, when she joined the Eckert-Mauchly Computer Corporation, led by the designers of the groundbreaking ENIAC computer system. There, she developed one of the world's first compilers and compiler-based programming languages. In 1959, Hopper played an important role in defining a new easy-to- use programming language. The result was COBOL, probably the most successful programming language for business applications in history.

Behold The Pasta PC, a computer that has a nutrition label in addition to a spec sheet, because he used sheets of pasta as the case. It works, but between the build (consider the thermals) and the antiquity of the Atom-based computer he sacrificed to make it, it's pretty hinky. [via MeFi]
My wife said something one day joking about making a PC out of Pasta... Never joke with me on such things because I may just do it... and do it I have. Behold... The LASAGNA PC V.1 Clickbait you say?! NAY! This is the real deal. The first ever crazy PC build on this Channel, and the first ever Pasta PC in the world. You're welcome.
Beautiful as it is, I'll admit that I'm slightly disappointed he didn't actually bake a PC into a lasagne. You could get away with what, about 160° without melting stuff on the board? Tasty. Read the rest
Ken Shirriff presents Iconic consoles of the IBM System/360 mainframes.
This article describes the various S/360 models and how to identify them from the front panels. I'll start with the Model 30, a popular low-end system, and then go through the remaining models in order. Conveniently IBM assigned model numbers rationally, with the size and performance increasing with the model number, from the stripped-down but popular Model 20 to the high-performance Model 195.
Each of the cabinets in the photo above contains a whopping 256 kilobytes of storage.

Read the rest"Think of them as nano apps," says Damien Woods, professor of computer science at Maynooth University near Dublin, Ireland, and one of two lead authors of the study. "The ability to run any type of software program without having to change the hardware is what allowed computers to become so useful. We are implementing that idea in molecules, essentially embedding an algorithm within chemistry to control chemical processes."
The system works by self-assembly: small, specially designed DNA strands stick together to build a logic circuit while simultaneously executing the circuit algorithm. Starting with the original six bits that represent the input, the system adds row after row of molecules—progressively running the algorithm. Modern digital electronic computers use electricity flowing through circuits to manipulate information; here, the rows of DNA strands sticking together perform the computation. The end result is a test tube filled with billions of completed algorithms, each one resembling a knitted scarf of DNA, representing a readout of the computation. The pattern on each "scarf" gives you the solution to the algorithm that you were running. The system can be reprogrammed to run a different algorithm by simply selecting a different subset of strands from the roughly 700 that constitute the system.
Over at EDGE.org, the must-read hub of intellectual inquiry and head-spinning science, Boing Boing pal and legendary book agent John Brockman is launching a new series of essays "from important third culture thinkers to address the empirically-driven and science related hot-button cultural issues of our time." First up is author George Dyson's "Childhood's End," a provocative riff on how the digital revolution has stripped much of our individual agency and that "to those seeking true intelligence, autonomy, and control among machines, the domain of analog computing, not digital computing, is the place to look." From EDGE:
Read the restThe spectacular success of digital computers in modeling real-world phenomena, encoded as algorithms with the results used as output to control something in the real world, has outshadowed very different ways that digital computers, and networks of digital computers, can be used. Algorithms and digital simulations have become so embedded in our culture and world view that we find it almost impossible to recognize that other forms of computation, without algorithms or digital models, effectively control much of the world.
We assume that a search engine company builds a model of human knowledge and allows us to query that model, or that some other company (or maybe it’s the same company) builds a model of road traffic and allows us to access that model, or that yet another company builds a model of the social graph and allows us to join that model — for a price we are not quite told.
A rare, fully-operational Enigma cipher machine from World War II will go up for auction at Sothebys tomorrow as part of an amazing History of Science & Technology auction (also including Richard Feynman's Nobel Prize). The Enigma is expected to go for around $200,000.
From a 1999 article I wrote for Wired:
Read the restGerman soldiers issued an Enigma were to make no mistake about their orders if captured: Shoot it or throw it overboard. Based on electronic typewriters invented in the 1920s, the infamous Enigma encryption machines of World War II were controlled by wheels set with the code du jour. Each letter typed would illuminate the appropriate character to send in the coded message.
In 1940, building on work by Polish code breakers, Alan Turing and his colleagues at the famed UK cryptography center Bletchley Park devised the Bombe, a mechanical computer that deciphered Enigma-encoded messages. Even as the Nazis beefed up the Enigma architecture by adding more wheels, the codes could be cracked at the Naval Security Station in Washington, DC - giving the Allies the upper hand in the Battle of the Atlantic. The fact that the Allies had cracked the Enigma code was not officially confirmed until the 1970s.

Paul Allen, billionaire co-founder of Microsoft, philanthropist, science fiction fan, and founder of Seattle's Museum of Pop Culture (formerly the Experience Museum Project), has died from complications of non-Hodgkin’s lymphoma. He was 65.
"From technology to science to music to art, I’m inspired by those who’ve blurred the boundaries, who’ve looked at the possibilities, and said, “What if...? In my own work, I’ve tried to anticipate what’s coming over the horizon, to hasten its arrival, and to apply it to people’s lives in a meaningful way." -- Paul Allen
Allen's professional timeline is quite something:
1953: Paul Allen is born January 21, 1953 in Seattle, Washington 1968: While at Lakeside School, Paul meets Bill Gates. A friendship that would later produce one of the world’s most innovative companies, Microsoft. 1969: Attends first rock concert, where he sees Jimi Hendrix at Seattle Center Coliseum 1975: Founds Microsoft 1982: In September, Paul is diagnosed with Hodgkin’s lymphoma.

Sandsifter throws random machine code instructions at microprocessors, just to see what happens.
The sandsifter audits x86 processors for hidden instructions and hardware bugs, by systematically generating machine code to search through a processor's instruction set, and monitoring execution for anomalies. Sandsifter has uncovered secret processor instructions from every major vendor; ubiquitous software bugs in disassemblers, assemblers, and emulators; flaws in enterprise hypervisors; and both benign and security-critical hardware bugs in x86 chips.
With the multitude of x86 processors in existence, the goal of the tool is to enable users to check their own systems for hidden instructions and bugs.
