Say you had received 10 bitcoins, you would have a private key which could generate a matching signature to unlock the public key it was transferred to.
When you spend say 4 coins, you create a transaction and publish it to the network. This transaction consists of
1) A point to the place in history where it was transferred to you
2) An amount, 4 bitcoins and an address of a recepient public key
3) An amount, 6 bitcoins and an address of a new public key you have just generated, and hold the private key for
Any attempt to respend this coin would be rejected by the network as it has been marked as used. To spend the remaining 6 you would have to point to its new location and if you had restored your wallet to an old version you'd have lost the private key for that, thus losing you all 10 sadly.
Apple Removes Wi-Fi Finders From App Store 461
jasonbrown writes "Apple on Thursday began removing another category of apps from its iPhone App Store. This time, it's not porn, it's Wi-Fi. Apple removed several Wi-Fi apps commonly referred to as stumblers, or apps that seek out available Wi-Fi networks near your location. According to a story on Cult of Mac, apps removed by Apple include WiFi-Where, WiFiFoFum, and yFy Network Finder."

I've not deployed DNSSEC, but i was interested by your comments about exposing zone data at least.
I did a quick google and it suggests that used to be the case but from bind 9.6.0 onwards it can use NSEC3 to hash the child names.
Worth looking into for anyone who is concerned.
Astronomers Discover the Coolest Known Sub-Stellar Body 60
Hugh Pickens writes "Science Daily reports that using the United Kingdom Infrared Telescope (UKIRT) in Hawaii, astronomers have discovered what may be the coolest sub-stellar body ever found outside our own solar system. Too small to be stars and with insufficient mass to maintain hydrogen-burning nuclear fusion reactions in their cores, 'brown dwarfs' have masses smaller than stars but larger than gas giant planets like Jupiter, with an upper limit in between 75 and 80 Jupiter masses. 'This looks like the fourth time in three years that the UKIRT has made a record breaking discovery of the coolest known brown dwarf, with an estimated temperature not far above 200 degrees Celsius,' says Dr. Philip Lucas at the University of Hertfordshire. Due to their low temperature these objects are very faint in visible light, and are detected by their glow at infrared wavelengths. The object known as SDSS1416+13B is in a wide orbit around a somewhat brighter and warmer brown dwarf, SDSS1416+13A, and the pair is located between 15 and 50 light years from the solar system, which is quite close in astronomical terms."

What the hell is a bad performance improvement?
Must be similar to a positive regression.
Submission + - NITdroid : GNU/Linux Android on Nokia n770+ (newlc.com)
rzr writes: "For the ones, who didn't notice that GNU/Linux Android is ported to many (if not all) platforms...
After the n810, now the n770 can support Android..
Note that n770 is the weakest Nokia Internet Tablet (64MB 252MHz) and near to become obsolete since Nokia did not release any updated firmware for years now (beside hacker's editions which are more buggy than official releases).
Don't set this fantastic little toy aside yet, since it's quite easy to install NITdroid if you follow this tutorial (w/ video)
The project is called NITdroid , the community is growing and a new website is about be online.
All this was possible because android and maemo are opensource and the most important : a few hackers devoted their time on this just because it was possible..."

Submission + - Community Codesigning Certificate for J2ME (darkskiez.co.uk)
darkskiez writes: "Nokia have "fixed" a bug which allowed you to install your own root certificates on your own mobile phones, this is no longer possible on Series60 v3 phones. This means that as a hobby developer you cannot make a mobile java application that runs as trusted with full api permissions, without purchasing a $300 to $500 certificate per year. This looks like it is being relaxed a little in the upcoming 3rd generation Mobile Information Device Profile.
In an attempt to reclaim a little more access to their own hardware, there has been limited success at patching some phone firmwares, and I have started a project to facilitate the purchasing of a shared codesigning certificates for the community."
