Submission + - BitMessage: all the good things of bitcoin applied to e-mail (bitmessage.org)

flok writes: BitMessage allows you to send e-mails truly anonymous. It also hides from where you're sending, to what location you send your message to and the contents of the e-mail. It is like using PGP/GPG but without the hassle of distributing keys. The way it does all of this (technically) is copied from bitcoin. Remembering a BitMessage address might be a bit of a challenge though (e.g. BM-Gu86guT7aSL68SuMd7Uhkq9tYcAc7Hti).

Submission + - pinging a webserver like a pro (vanheusden.com)

flok writes: Pinging a webserver used to be boring. An endless of stream of black on white text with uninteresting numbers that no-one comprehends.
An end has come to this depressing situation with HTTPing v2.3.1!
This program which not only measures the network-latency but also the responsiveness of the webserver itself, introduces fancy graphics with lots of colors compatible with every terminal capable of displaying ncurses output!
Check out the youtube video to see what this is all about.

Submission + - Rise of the Bitcoin (ieee.org)

An anonymous reader writes: IEEE Spectrum has an article on the new custom built ASIC Bitcoin mining machines. Featured in the article is 66 billion hashes/second rig, and that is twice the speed of the best FPGA rig on the market. The whole thing is feeling more like custom car racing everyday.

Submission + - Tylenol may ease pain of existential distress, social rejection

Guppy writes: Does Tylenol reduce existential distress? Acetaminophen (Paracetamol) has been used to relieve mild-to-moderate physical pain for over a century, yet its actual mechanism of action continues to be debated; modern research has demonstrated an intriguing connection with the body's endocannabinoid system, raising the question of whether it may also have subtle psychological effects as well. A recent paper claims Acetaminophen can alter our response to existential challenge; previous findings have suggested that it may blunt the pain of social rejection as well.

Submission + - Get paid for your open source software enhancements/bugfixes (catincan.com) 1

flok writes: It is nice when your open source pet project is populair but sometimes the constant stream of feature requests can be intimidating. The CatInCan website can help you with prioritizing your efforts while making some money on the side. See it as a Kickstarter-variant where people can raise funds to get functionality in software realised or maybe to get that long ignored bug fixed. It works a most people like a financial incentive!

Submission + - OpenWLANMap - the free GPS replacement (openwlanmap.org)

flok writes: There are a couple of commercial products which can tell you where you are by the mac addresses from access points in your neighbourhood. E.g. the iphone uses this. There's now an open offering for this: OpenWLANMap. With this website, you can enter your access point mac address with your GPS location and then others can use that to navigate. There is also an App for your mobile which automatically enters this data and you can upload data from e.g. Airomap and other wardriving applications.

Submission + - Bill Gates and Paul Allen recreate the famous 1981 Microsoft photo (pureinfotech.com)

Krnl678 writes: One of the greatest fortunes in the history of the world started in 1981 when Bill Gates and Paul Allen, Microsoft co-founder, made a deal to license MS-DOS to IBM while retaining ownership of the software. To stamp the moment in history, they both took a picture surrounded by computer systems popular at that time; and now 32 years later Bill Gates and Paul Allen once again got together to recreate the iconic photograph.

Submission + - Internet Status

ZeroFactiX writes: So here's my question for everyone. I'm looking for the best site for monitoring the Internet backbone/ Core Routers. I've seen a few sites out there but nothing that has really impressed me. What I would like to see is just the status of the core routers/Hubs perferably with RSS/Twitter feed. I know each provider usually has a little status page, but they are hard to find and it is not worth looking up every site to look for an issue. Reason being is that lastnight there was an outage with Level3 which didn't last long but was a pain to verify.

So who's got a good tool?

Submission + - World's Biggest Bitcoin Exchange Under Major DDoS Attack

twoheadedboy writes: As the value of Bitcoins hit new highs this week of $142 per coin, the biggest exchange claimed to have been on the wrong end of a "major DDoS attack". Japan-based Mt.Gox said it appeared there were two motivations behind the attacks. First, to destabilise Bitcoin and, second, to abuse the system for profit. "“Attackers wait until the price of Bitcoins reaches a certain value, sell, destabilize the exchange, wait for everybody to panic-sell their Bitcoins, wait for the price to drop to a certain amount, then stop the attack and start buying as much as they can," the company said. Meanwhile, Bitcoin wallet site Instawallet has shut down, with security problems to blame. The company was hit by a breach earlier this week.

Submission + - Bitcoin: The Future of Global Currency? (newyorker.com)

An anonymous reader writes: As hard currencies the world over rise and fall with abandon reckless as the governments that print them and the banks that tender them, people are turning in ever larger numbers to decentralized electronic currency like bitcoin. "So is bitcoin going to save the global economy, or is it today’s answer to seventeenth-century tulip mania?" The New Yorker weighs in ...
