Converting 32-bit code to 64-bit code

Some resources for avoiding pitfalls when moving C or C++ software from a 32-bit computer to a 64-bit computer:

In 2008, legendary computer scientist Donald Knuth complained about gcc on 64-bit platforms forcing the wasteful use of 64-bit pointers, when 32-bit pointers would suffice, and that the man page advertised an option to permit this, although it's only available for the obsolete MIPS platform. This Ubuntu bug page pursues the question.

A collection of useful tools for converting between machine-readable and human-readable timestamps. (The Unix Epoch is the number of seconds since midnight GMT January 1, 1970. This number is used for file creation and modification times and other system purposes.)

Windows audio patch for Dorling Kindersley DK software

If you're trying to run an old educational CD-ROM game by Dorling Kindersley (DK) on Windows XP, you'll probably see an error message like this:

"Sound Software is not installed properly or has been disabled" or "1058 Sound Decompression Software not installed properly".

There's a patch to fix the problem. It's available through Global Software Publishing's support website. (GSP bought the DK Interactive Learning back catalog.) Here is a direct link to the DK audio patch file.

DIY machine shop: Four essential tools you can build from recycled parts | News | Engineering for Change

Pat Delany's open-source designs for human-powered machine tools that can be built with inexpensive scrap for about $200. The Multimachine, built out of an auto engine block, serves as a grinder, mill, lathe, and saw. The 16" swing screw-cutting lathe is made of concrete and scrap steel, using techniques that date back to World War I. A hand-powered drill can be built with scrap wood and parts for $1. A treadle-powered generator uses a car's alternator to turn human power into electricity that can charge batteries and mobile phones. (A commenter suggests "a flywheel on the bottom horizontal shaft, at the opposite end of the shaft to the large driving wheel. Firstly, this would stop the frame from toppling over if the ground was uneven. Secondly, once the mechanism was up to speed, the effort required would be much less than the initial start-up; it would simply be a case of keeping the flywheel up to speed.")

Delany and his open-source designs are featured in the latest issue of Makezine. has even more information on these projects and historical do-it-yourself machine building.

MORE: The Open Source Machine site also has how-to articles for building an air compressor, hydraulic press, and screw press, for blacksmithing, and farm shop work from the early 20th century and U. S. Army courses on drafting, welding, machine tools, lathes, milling machines, and band saws.

Doctor Sam Parnia Believes Resurrection Is A Medical Possibility - SPIEGEL ONLINE

Resuscitation science has advanced tremendously, but the key techniques to bringing someone back from cardiac arrest aren't as widely known and used as they should be, says the author of Erasing Death. Chest compressions, no more than 8 breaths a minute with an ambu bag, cooling the body (down to about 32 degrees Celsius, or about 90 degrees Fahrenheit). "We use pads that get attached to the thighs and the upper body. In a matter of hours, the cooling machine brings the body temperature down to the desired level. But you could also do this at home, if you found someone there in cardiac arrest. Call an ambulance, administer CPR and place a bag of frozen peas or other frozen vegetables on the patient. It helps to protect the brain....

"Most brain damage after resuscitation occurs not within the first few minutes of death, but in the hours up to the first 72 hours after resuscitation. But with proper post resuscitation care, we can minimize that.... A recent study found that the optimal length of resuscitation to yield higher survival is at least 40 minutes. Yet most doctors will stop within 20 minutes.... As long as hospitals don't require their resuscitation doctors to implement all the nuances required to save brains and lives after cardiac arrest through fully trained specialists, survival rates in general will not improve."
