Slashdot reader RockDoctor brings an update on a project to build Babbage’s Analytical Engine: Between 1822 and 1847, Charles Babbage worked on a number of designs for general-purpose programmable computing engines, some parts of which were built during his lifetime and after. Since 2011 a group under the name of “Plan-28” have been working towards building a full version of the machine known as the Analytical Engine. (The group’s name refers to the series of Babbage’s plans which they are working to — versions 1 to 27 obviously having problems.) This week, they’ve released some updates on progress on their blog. Significant progress includes working on the machine’s “internal microcode” (in today’s terminology; remember, this is a machine of brass cogs and punched cards!) [and] archive work to bring the Science Museum’s material into a releasable form (the material is already scanned, but the metadata is causing eyestrain). “One of the difficulties in understanding the designs is the need to reverse engineer logical function from mechanical drawings of mechanisms — this without textual explanation of purpose or intention…” Progress is slow, but real. Last year marked the bicentennial of Ada Lovelace, who wrote programs for the Analytical Engine and it’s predecessor, the Difference Engine, and whose position as “the world’s first programmer” is celebrated in the name of the programming language Ada.

Researchers Are Reconstructing Babbage’s Analytical Engine

For that sum you could build a small forest of Burj Khalifas — the world’s tallest building, in Dubai, which each cost $1.5 billion. You could build almost six Large Hadron Colliders, built under the border between France and Switzerland to unlock the secrets of the universe, and at a cost a mere $5.8 billion. Or you could build five Oakland Bay Bridges in San Francisco, designed to withstand the strongest earthquake seismologists would expect within the next 1, 500 years at a cost of $6.5 billion… But what about historical buildings like the the pyramids. Although working out the cost of something built more than 4, 500 years ago presents numerous challenges, in 2012 the Turner Construction Company estimated it could build the Great Pyramid of Giza for $5 billion. That includes about $730 million for stone and $58 million for 12 cranes. Labor is a minor cost as it is projected that a mere staff of 600 would be necessary. In contrast, it took 20, 000 people to build the original pyramid with a total of 77.6 million days’ labor. Using the current Egyptian minimum wage of $5.73 a day, that gives a labor cost of $445 million. But whatever the most expensive object on Earth is, up in the sky is something that eclipses all of these things. The International Space Station. Price tag: $110 billion.

An anonymous reader writes: Humble Bundle announced a special “pay what you want” sale for four ebooks from No Starch Press, with proceeds going to the Electronic Frontier Foundation (or to the charity of your choice). This “hacker edition” sale includes two relatively new titles from 2015 — “Automate the Boring Stuff with Python” and Violet Blue’s “Smart Girl’s Guide to Privacy, ” as well as “Hacking the Xbox: An Introduction to Reverse Engineering” by Andrew “bunnie” Huang, and “The Linux Command Line”. Hackers who are willing to pay “more than the average” — currently $14.87 — can also unlock a set of five more books, which includes “The Maker’s Guide to the Zombie Apocalypse: Defend Your Base with Simple Circuits, Arduino, and Raspberry Pi”. (This level also includes “Bitcoin for the Befuddled” and “Designing BSD Rootkits: An Introduction to Kernel Hacking”.) And at the $15 level — just 13 cents more — four additional books are unlocked. “Practical Malware Analysis: The Hands-On Guide to Dissecting Malicious Software” is available at this level, as well as “Hacking: The Art of Exploitation” and “Black Hat Python.” Nice to see they’ve already sold 28, 506 bundles, which are DRM-free and available in PDF, EPUB, and MOBI format. (I still remember Slashdot’s 2012 interview with Make magazine’s Andrew “bunnie” Huang, who Samzenpus described as “one of the most famous hardware and software hackers in the world.”) Read more of this story at Slashdot.
