Graphics on a Z80 system built in Yugoslavia. "The animation software was executed on my DIY TRS-80 clone with the 6MHz Z80B microprocessor, so one frame took a mere 10 minutes of rendering time, which translated to 24 hours for an average shot."  A few years later +Voja Antonic designed the Galaksija DIY Microcomputer and published the project in the first issue of “Računari u vašoj kući” (Computers in Your Home).

Interesting. At my last job they used forth on their embedded systems, so I had to learn it. It's not bad once I got past the learning curve a bit. The fact that you can add new words interactively is very handy for testing.
I was thinking it might be good to use in an fpga like this demo.
Cool!

When you sell bulk online storage cheap, how do you deal with a sudden increase in hard drive failure rates?
In August 2011 flooding in Thailand dramatically reduced supply of hard drives, and prices went up. Backblaze's business is unlimited write-mostly storage for $5/month, and they saved a million dollars by buying and shucking external hard drives instead of buying internal drives. But over the next year or so drives bought in this period showed shockingly high failure rates. Here's what they did, and what they found.
(For more recent 4TB drives, they note that things are looking a great deal better. Also note "nearly every manufacturer reduced the warranty on their drives during the crisis with consumer drives like the Seagate model ST3000DM001 being reduced from 3 years to 1 year")
Beginning in January 2012, Backblaze deployed 4,829 Seagate 3TB hard drives, model ST3000DM001, into Backblaze Storage Pods. In our experience, 80% of the hard drives we deploy will function at least 4 years. As of March 31, 2015, just 10% of the Seagate 3TB drives deployed in 2012 are still in service. This is the....

A big collection of retro-reading recommendations from +Blake Patterson - from The Soul of a New Machine to Masters of Doom by way of On the Edge and Insanely Great

Regular readers are likely aware of Tracy Kidder's Pulitzer Prize-winning book The Soul of a New Machine, an inside look at the experience of a team of Data General engineers racing to design a next-generation minicomputer back in the 1970s. It's an fascinating and highly enjoyable read that set ...

Quick game to find out how soon your regexp knowledge runs out.
 
Øv dig på regular expressions med Regex Golf. Sjovt.
Perfect! Hit Enter to try the next level (or see if you can make it shorter for more points). You have all the original test cases covered, but I tried some at random and found . Hmm... loading, I hope? If this doesn't work, maybe the old version does?

I have a very flexible Regex debugger that I run last calls, which tells me how good ( or not ) my Regex is. Which flavor of Regex does this game support??

Here's a nice retro idea: get hold of the 1980-vintage chess programs and devices and pit them against each other in a rerun of the first World Microcomputer Chess Championship. Unfortunately I can only find the first round of this rerun. It's pleasing to see so many 6502-based machines here though!
For Peter Jennings' telling of his groundbreaking 1k chess for the KIM, see here:
http://www.benlo.com/microchess/index.html
But if you prefer 1k chess on the Z80 in a ZX81, see

"My view of the country is intimate and messy. The best advice I can give to my fellow Americans after thirty years of China watching is that the more definitive a U.S expert assessment of China appears to be, the less likely it is to be true."
"The ground truth of my experience in the country did not support the narratives about China I studied in school. Every time I return to China the unlearning continues."
Thirty years ago this month my first year in China came to an end. What I remember most is that I returned to the United States assured I knew less about China than when I first arrived. It was a year of unlearning. The ground truth of my experience in the country did not support the narratives ...

How to survive on Venus, at least for a couple of hours - the evolving designs of the Soviet Venera probes.
Edit: I hadn't realised communications were lost for radio reasons, not probe survival reasons. "Venera-11 landed at 14° S 299° E. Conditions there were 92.6 atmospheres of pressure and a temperature of 452° C (846° F). It remained in radio contact for 95 minutes, until the bus vehicle moved out of range."
I've been reading about Russia's (former Soviet Union) Venera missions, and one thing about them that has impressed me is the incremental improvements the landers made in their lifespans before
