An anonymous reader shares a report: Researchers Neil Gandal, JT Hamrick, Tyler Moore, and Tali Oberman have written a fascinating paper on Bitcoin price manipulation. Entitled "Price Manipulation in the Bitcoin Ecosystem" and appearing in the recent issue of the Journal of Monetary Economics the paper describes to what degree the Bitcoin ecosystem is controlled by bad actors. To many it's been obvious that the Bitcoin markets are, at the very least, being manipulated by one or two big players. "This paper identifies and analyzes the impact of suspicious trading activity on the Mt. Gox Bitcoin currency exchange, in which approximately 600,000 bitcoins (BTC) valued at $188 million were fraudulently acquired," the researchers wrote. "During both periods, the USD-BTC exchange rate rose by an average of four percent on days when suspicious trades took place, compared to a slight decline on days without suspicious activity. Based on rigorous analysis with extensive robustness checks, the paper demonstrates that the suspicious trading activity likely caused the unprecedented spike in the USD-BTC exchange rate in late 2013, when the rate jumped from around $150 to more than $1,000 in two months." The team found that many instances of price manipulation happened simply because the market was very thin for various cryptocurrencies including early Bitcoin.Read Replies (0)

Accurate location data is on smartphones, so why don't more wireless carriers use it to locate emergency callers? From a report, shared by a reader: Software on Apple's iPhones and Google's Android smartphones help mobile apps like Uber and Facebook to pinpoint a user's location, making it possible to order a car, check in at a local restaurant or receive targeted advertising. But 911, with a far more pressing purpose, is stuck in the past. U.S. regulators estimate as many as 10,000 lives could be saved each year if the 911 emergency dispatching system were able to get to callers one minute faster. Better technology would be especially helpful, regulators say, when a caller can't speak or identify his or her location. After years of pressure, wireless carriers and Silicon Valley companies are finally starting to work together to solve the problem. But progress has been slow. Roughly 80% of the 240 million calls to 911 each year are made using cellphones, according to a trade group that represents first responders. For landlines, the system shows a telephone's exact address. But it can register only an estimated location, sometimes hundreds of yards wide, from a cellphone call. That frustration is now a frequent source of tension during 911 calls, said Colleen Eyman, who oversees 911 services in Arvada, Colo., just outside Denver.Read Replies (0)

Lasrick shares "Don't fear the robopocalypse," an interview from the Bulletin of the Atomic Scientists with the former Army Ranger who led the team that established the U.S. Defense Department policy on autonomous weapons (and has written the upcoming book Army of None: Autonomous Weapons and the Future of War). Paul Scharre makes the case for uninhabited vehicles, robot teammates, and maybe even an outer perimeter of robotic sentries (and, for mobile troops, "a cloud of air and ground robotic systems"). But he also argues that "In general, we should strive to keep humans involved in the lethal force decision-making process as much as is feasible. What exactly that looks like in practice, I honestly don't know."
So does that mean he thinks we'll eventually see the deployment of fully autonomous weapons in combat?
I think it's very hard to imagine a world where you physically take the capacity out of the hands of rogue regimes... The technology is so ubiquitous that a reasonably competent programmer could build a crude autonomous weapon in their garage. The idea of putting some kind of nonproliferation regime in place that actually keeps the underlying technology out of the hands of people -- it just seems really naive and not very realistic. I think in that kind of world, you have to anticipate that there are, at a minimum, going to be uses by terrorists and rogue regimes. I think it's more of an open question whether we cross the threshold into a world where nation-states are using them on a large scale.

An anonymous reader quotes Open Source Observatory:
The City of Barcelona is migrating its computer systems away from the Windows platform, reports the Spanish newspaper El País. The City's strategy is first to replace all user applications with open-source alternatives, until the underlying Windows operating system is the only proprietary software remaining. In a final step, the operating system will be replaced with Linux... According to Francesca Bria, the Commissioner of Technology and Digital Innovation at the City Council, the transition will be completed before the current administration's mandate ends in spring 2019. For starters, the Outlook mail client and Exchange Server will be replaced with Open-Xchange. In a similar fashion, Internet Explorer and Office will be replaced with Firefox and LibreOffice, respectively. The Linux distribution eventually used will probably be Ubuntu, since the City of Barcelona is already running 1,000 Ubuntu-based desktops as part of a pilot...
Barcelona is the first municipality to have joined the European campaign 'Public Money, Public Code'. This campaign is an initiative of the Free Software Foundation Europe (FSFE) and revolves around an open letter advocating that publicly funded software should be free. Currently, this call to public agencies is supported by more than 100 organisations and almost 15,000 individuals. With the new open-source strategy, Barcelona's City Council aims to avoid spending large amounts of money on licence-based software and to reduce its dependence on proprietary suppliers through contracts that in some cases have been closed for decades.Read Replies (0)

An anonymous reader quotes BleepingComputer:
Unknown hackers (or hacker) have hijacked the DNS server for BlackWallet.co, a web-based wallet application for the Stellar Lumen cryptocurrency (XLM), and have stolen over $400,000 from users' accounts. The attack happened late Saturday afternoon (UTC timezone), January 13, when the attackers hijacked the DNS entry of the BlackWallet.co domain and redirected it to their own server. "The DNS hijack of Blackwallet injected code," said Kevin Beaumont, a security researcher who analyzed the code before the BlackWallet team regained access over their domain and took down the site. "If you had over 20 Lumens it pushes them to a different wallet," Beaumont added... According to Bleeping Computer's calculations, as of writing, the attacker collected 669,920 Lumens, which is about $400,192 at the current XML/USD exchange rate. The BlackWallet team and other XLM owners have tried to warn users via alerts on Reddit, Twitter, GitHub, the Stellar Community and GalacticTalk forums, but to no avail, as users continued to log into the rogue BlackWallet.co domain, enter their credentials, and then see funds mysteriously vanish from their wallets.Read Replies (0)

"Most code remains closed and proprietary, even though open source now dominates enterprise platforms," notes Matt Asay, former COO at Canonical (and an emeritus board member of the Open Source Initiative). "How can that be?" he asks, in an essay noting it's been almost 20 years since the launch of the Open Source Initiative, arguing that so far open source "hasn't changed the world as promised."
[T]he reason most software remains locked up within the four walls of enterprise firewalls is that it's too costly with too small of an ROI to justify open-sourcing it. At least, that's the perception. Such a perception is impossible to break without walking the open source path, which companies are unwilling to walk without upfront proof. See the problem? This chicken-and-egg conundrum is starting to resolve itself, thanks to the forward-looking efforts of Google, Facebook, Amazon, and other web giants that are demonstrating the value of open-sourcing code.
Although it's unlikely that a State Farm or Chevron will ever participate in the same way as a Microsoft, we are starting to see companies like Bloomberg and Capital One get involved in open source in ways they never would have considered back when the term "open source" was coined in 1997, much less in 2007. It's a start. Let's also not forget that although we have seen companies use more open source code over the past 20 years, the biggest win for open source since its inception is how it has changed the narrative of how innovation happens in software. We're starting to believe, and for good reason, that the best, most innovative software is open source.
The article strikes a hopeful note. "We're now comfortable with the idea that software can, and maybe should, be open source without the world ending. The actual opening of that source, however, is something to tackle in the next 20 years.Read Replies (0)

An anonymous reader quotes Engadget:
If you're starting a pop group in Japan, where giant rosters and virtual superstars are par for the course, how do you stand out? By tying yourself to something trendy -- and in 2018, that means cryptocurrency. Meet Kasotsuka Shojo (Virtual Currency Girls), a J-pop group where each of the eight girls represents one of the larger digital monetary formats. Yes, you're supposed to cheer for bitcoin or swoon over ethereum (what, no litecoin?). The group played its first concert on January 12th, and naturally you had to pay in cryptocurrency to be one of the few members of the general public to get in. The group's first single, "The Moon and Virtual Currencies and Me," warns listeners about the perils of fraud and extols the virtues of good online security.
"It isn't clear how French maid outfits symbolize cryptocurrency or blockchain technology," notes Quartz, "but they're popular costumes in Japan's anime and cosplay circles."Read Replies (0)

On the fifth anniversary of the death of Aaron Swartz, EFF activist Elliot Harmon posted a remembrance:
When you look around the digital rights community, it's easy to find Aaron's fingerprints all over it. He and his organization Demand Progress worked closely with EFF to stop SOPA. Long before that, he played key roles in the development of RSS, RDF, and Creative Commons. He railed hard against the idea of government-funded scientific research being unavailable to the public, and his passion continues to motivate the open access community. Aaron inspired Lawrence Lessig to fight corruption in politics, eventually fueling Lessig's White House run... It's tempting to become pessimistic in the face of countless threats to free speech and privacy. But the story of the SOPA protests demonstrates that we can win in the face of seemingly insurmountable odds.
He shares a link to a video of Aaron's most inspiring talk, "How We Stopped SOPA," writing that "Aaron warned that SOPA wouldn't be the last time Hollywood attempted to use copyright law as an excuse to censor the Internet... 'The enemies of the freedom to connect have not disappeared... We won this fight because everyone made themselves the hero of their own story. Everyone took it as their job to save this crucial freedom. They threw themselves into it. They did whatever they could think of to do.'"
On the anniversary of Aaron's death, his brother Ben Swartz, an engineer at Twitch, wrote about his own efforts to effect change in ways that would've made Aaron proud, while Aaron's mother urged calls to Congress to continue pushing for reform to the Computer Fraud and Abuse Act.
And there were countless other remembrances on Twitter, including one fro Cory Doctorow, who tweeted a link to Lawrence Lessig's analysis of the prosecution. And Lessig himself marked the anniversary with several posts on Twitter. "None should rest," reads one, "for still, there is no peace."Read Replies (0)
