Operation Wants To Mine 10% of All New Bitcoins 275

An anonymous reader writes: "Mining new Bitcoins is computationally expensive — you can't expect to do much on your standard home computer. Many miners have built custom rigs to mine more efficiently, but it was only a matter of time until somebody went industrial. Dave Carlson's goal is to mine 10% of all new Bitcoins from now on. He's built literally thousands of units. They collectively use 1.4 million BitFury mining chips, which are managed by a bunch of Raspberry Pis. 'The current rigs each contain 16 boards, with each board containing 16 BitFury chips, for a total of 256 mining chips on each rig. Carlson said about 90,000 processor boards have been deployed, which would put the number of rigs at about 5,600. A new board [being designed] will have 756 chips on each rig instead of 256.' Carlson says his company spent $3-5 million to get everything set up. They current generate 7,000 — 8,000 Bitcoins per month, which, at current rates, would be worth over $4 million."

New submitter Covalent writes "I'm a science teacher and have, over the years, accumulated a number of lost graphing calculators (mostly TI-83s). After trying to locate the owners, I have given up and have been loaning them out to students as needed. I want to something more nerd-worthy with them, though. I would feel wrong for selling them. What is the best use for bunch of old calculators?"

BitCoin Card To Launch In 2 Months, Says BitInstant 216

hypnosec writes "Charlie Shrem, co-founder of BitInstant LLC, has confirmed that a BitCoin-funded international debit/credit card should be available very soon. Giving a time frame of 6-8 weeks, Shrem said over an IRC chat session that the card will function like any other credit or debit card, and that it can be used at places where MasterCard is being accepted. Shrem has also said that the initial 1000-odd cards will be given for free and subsequent cards will carry a charge of around $10. Any transaction that is carried out through the card [will incur a] 1% BitCoin transfer fee on top of the $1.50 ATM withdrawal fee."

. IMHO the best feature Debian has is the ability to upgrade-in-place -- so you never have to do a reinstall to keep it up-to-date unless you want to.

Indeed, I have installations of Debian that are 13 years old. They've been through multiple hardware revisions, and are now virtualized, but apt-get dist-upgrade has done the trick all this time.

However, technical achievements aside, it's Debian's policy that's the real star.
