  • Officials from Indonesia’s nuclear energy regulatory agency have traced the source of contamination to a steel manufacturer in the Cikande industrial area known as Peter Metal Technology, or PMT. Some of the highest levels of contamination detected in the area were reportedly found in the company’s furnace, which is about 1.5 miles southwest of the BMS Foods facility where the shrimp was processed.

    Investigators think that radioactive dust was released into the environment after PMT inadvertently smelted scrap metal containing cesium-137. “Because it’s airborne, the contamination can be carried by wind,” said Bara Khrishna Hasibuan, a senior adviser to Indonesia’s Ministry of Food Affairs, at a Sept. 30 press conference.

    Scrap metal was commonly used as a raw material by PMT, according to the Indonesian outlet Antara News. It’s unclear how it may have become contaminated with cesium-137. Biegalski, whose area of expertise includes nuclear forensics, told CR that the “easiest explanation” is that a medical or industrial device containing cesium-137 was inadvertently reprocessed as scrap metal. The radioactive material could have become gaseous after entering the PMT furnace and then been released from the facility’s smokestack, he said.

















  • But if someone creates a file called HEAD, should it overwrite a file called head?

    That shouldn’t matter to the “nontechnical” end-user at all. To the nontechnical user, even the abstraction of “creating a file” has largely gone away. You create a document, and changes you make to it are automatically persisted to storage, either local or cloud.

    Only the technical command-line user cares about whether /usr/bin/HEAD and /usr/bin/head are the same path. And only in a specific circumstance — such as the early days of Mac OS X, where the Macintosh and Unix cultures collided — could the bug that I described emerge.
