Aggrajag and Mortimer.CA, among others, wrote to inform us that Theo de Raadt has made public an email sent to him by Gregory Perry, who worked on the OpenBSD crypto framework a decade ago. The claim is that the FBI paid contractors to insert backdoors into OpenBSD's IPSEC stack. Mr. Perry is coming forward now that his NDA with the FBI has expired. The code was originally added ten years ago, and over that time has changed quite a bit, "so it is unclear what the true impact of these allegations are" says Mr. de Raadt. He added: "Since we had the first IPSEC stack available for free, large parts of the code are now found in many other projects/products." (Freeswan and Openswan are not based on this code.)

CNETNate writes "Is the American mains socket really so much worse than the Italian design? And does the Italian socket fail at rivaling the sockets in British homes? This feature explores, in a not-at-all-parodic-and-anecdotal fashion, the designs, strengths and weaknesses of Earth's mains adapters. There is only one conclusion, and you're likely not to agree if you live in France. Or Italy. Or in fact most places."

elREG writes to mention that Sun's ZFS now has built-in deduplication utilizing a master hash function to map duplicate blocks of data to a single block instead of storing multiples. "File-level deduplication has the lowest processing overhead but is the least efficient method. Block-level dedupe requires more processing power, and is said to be good for virtual machine images. Byte-range dedupe uses the most processing power and is ideal for small pieces of data that may be replicated and are not block-aligned, such as e-mail attachments. Sun reckons such deduplication is best done at the application level since an app would know about the data. ZFS provides block-level deduplication, using SHA256 hashing, and it maps naturally to ZFS's 256-bit block checksums. The deduplication is done inline, with ZFS assuming it's running with a multi-threaded operating system and on a server with lots of processing power. A multi-core server, in other words."
