Scientists make exotic chemicals with high-pressure salt

Everything around you is made of elements that scientists have studied in quite some detail over the last 200 years. But all that understanding breaks down when these elements are subjected to high pressure and temperature. Now, using an advanced theoretical understanding and extreme conditions, researchers have converted table salt into exotic chemicals. Salt is made from one part sodium (Na) and one part chlorine (Cl). If somehow salt were transported to the center of the Earth, where the pressure is three million times that on the surface, its crystalline structure would change but the ratio of those two elements would remain the same. Vitali Prakapenka at the University of Chicago and his colleagues wanted to find out what would happen if there were an excess of either sodium or chlorine at such high pressures. Would the ratio between the elements change? “It might,” said Prakapenka, “because chemistry completely changes in such conditions.” If it did, the result would not just be formation of a new compound, but a serious revision of what we think about chemistry.

After sailing the domain name seas, Pirate Bay returns to Sweden

Aurich Lawson After nearly two weeks of bouncing its domain name around the globe, The Pirate Bay has returned to its home port. The notorious BitTorrent site originally went from .se to .sx (Sint Maarten), but it didn’t stop there—in recent days, it has shifted from .ac (Ascension Island) to .pe (Peru) to .gy (Guyana). Now, as of Thursday, it’s back to the comforts of .se (Sweden). Neither The Pirate Bay blog nor its Twitter feed offered any explanation. The move to .sx originally took place back in April 2013 when a Swedish prosecutor filed a motion to seize thepiratebay.se, piratebay.se, and thepiratebay.is. The registrar, the Internet Infrastructure Foundation, has said previously that it would only do so after being served by a Swedish court. “Our actions would largely be determined by the contents of the order and the issuing party,” the agency wrote in June 2012. “Accordingly, we will assess the situation on a case-by-case basis if such an order is issued.” Read 3 remaining paragraphs | Comments

US report predicts CO2 emissions have peaked, energy independence near

Well-sited wind power is cheaper than coal, but the good sites aren’t evenly distributed throughout the US. NREL/DOE Although there are some reasonable questions about the value of making long-term projections about energy use, doing so is one of the duties of the US’ Energy Information Agency. On Monday, the EIA released an overview of a report in which it attempts to track the trends in the energy economy of the US out to 2040. The report contains some eye-popping predictions, including a huge (but brief) boom in domestic oil production, a near balance between energy imports and exports, and a peak in carbon emissions that’s already in our past. Energy predictions are fraught with uncertainty, but this report contains more than most, since it’s predicated on having the entire period out to 2040 covered by legislation and rules that are already on the books. At the moment, that would include the expiration of a tax credit that promotes the installation of renewable power facilities, something that Congress has already renewed several times. Perhaps more significantly, the EPA’s rules governing greenhouse gas emissions from existing facilities are still being formulated but are likely to be in effect for most of the period under consideration. This probably explains why the EIA predicts that the slice of domestic energy production that comes from renewables only increases from 11 to 12 percent over the next 30 years.

Exponential algorithm making Windows XP miserable could be fixed

Tom Carden Windows XP is really old, and we would suggest that you don’t use it unless you really have no option. For the most part, however, that age doesn’t really manifest itself. Sure, the operating system is missing the security features, hardware acceleration, and built-in support for things like USB 3 that newer versions of Windows have, but old software doesn’t have the same issues as, say, old cars. Old software generally runs as well today as it did when it was brand new. But Windows XP users have noticed that this isn’t entirely true. A bunch of them have found that the old operating system is working considerably worse than when it was released in 2001. The problem is that—especially among those who are still using Internet Explorer 6 or 7—each time you boot your Windows XP machine, it slows to a crawl. There’s a built-in process, svchost.exe, chewing up the entire processor, sometimes for an hour or more at a time. Wait long enough after booting and the machine will eventually return to normalcy. But an hour can be a long time to wait. Loss of horsepower and trouble starting up are common enough problems in old cars, but we don’t really expect the same things to happen on old PCs.

Botnet forces infected Firefox users to hack the sites they visit

Sites browsed by hacked PCs (left) and SQL injection flaws found by the botnet (masked, right). KrebsonSecurity Investigative journalist Brian Krebs has uncovered an unusual botnet that forces infected PCs to scour websites for security vulnerabilities that can cough up proprietary data or be exploited in drive-by malware attacks. The botnet, dubbed “Advanced Power” by its operators, has discovered at least 1,800 webpages vulnerable to SQL injection attacks since May, Krebs reported in a post published Monday . SQL injection vulnerabilities exploit weaknesses in Web applications that allow attackers to send powerful commands to a website’s backend databases. From there, attackers can download login credentials or other database contents or cause sites to post links that silently redirect visitors to malicious websites. Advanced Power masquerades as a legitimate add-on for Mozilla’s Firefox browser. Once installed, it looks for vulnerabilities on sites visited by the infected machine.

Everything you need to know to install SteamOS on your very own computer

SteamOS in all its blue glory. Lee Hutchinson True to its word, Valve has released a beta version of SteamOS, the Linux-based operating system that it will use to power its living room Steam Machine consoles. The release coincides with a lucky group of 300 public beta testers being selected to actually receive Steam Machines to test on—the rest of us can still use the OS, but we’ll have to bring our own hardware. Valve had previously recommended that users who aren’t “intrepid Linux hackers” should wait a few more months before trying out SteamOS, but that’s not going to stop Ars from barreling head first into the midst of things! We downloaded the OS as quickly as we could after it went live and spent some time getting it whipped into shape on fresh hardware. Contrary to Valve’s warning, the install wasn’t complex or scary at all—though if you’ve never installed Linux before, it might take you a bit out of your comfort zone. The hardware Specs at a glance:The Ars Technica Steam Machine CPU Intel Pentium G3220 (Haswell), dual-core, 3.0 GHz GPU Zotac Geforce GTX660 (2GB) RAM 8 GB DDR3-1600 Motherboard MSI H81I (mini-ITX) Storage Western Digital WD Blue 7200 rpm 500GB HD Sound Onboard Network Onboard (wired gigabit Ethernet) PSU Antec VP-450, 450W Case BitFenix Prodigy, arctic white We didn’t receive a Steam Machine to test, so we set out to build our own. Our goals were to stick to known-good SteamOS hardware, and to keep the price between $5-600. Andrew Cunningham, Kyle Orland, and I all stuck our heads together and came up with the configuration at right. All items were purchased from NewEgg, and the total prior to shipping was $562.93.

Gmail blows up e-mail marketing by caching all images on Google servers

Ever wonder why most e-mail clients hide images by default? The reason for the “display images” button is because images in an e-mail must be loaded from a third-party server. For promotional e-mails and spam, usually this server is operated by the entity that sent the e-mail. So when you load these images, you aren’t just receiving an image—you’re also sending a ton of data about yourself to the e-mail marketer. Loading images from these promotional e-mails reveals a lot about you. Marketers get a rough idea of your location via your IP address. They can see the HTTP referrer , meaning the URL of the page that requested the image. With the referral data, marketers can see not only what client you are using (desktop app, Web, mobile, etc.) but also what folder you were viewing the e-mail in. For instance, if you had a Gmail folder named “Ars Technica” and loaded e-mail images, the referral URL would be “https://mail.google.com/mail/u/0/#label/Ars+Technica”—the folder is right there in the URL. The same goes for the inbox, spam, and any other location. It’s even possible to uniquely identify each e-mail, so marketers can tell which e-mail address requested the images—they know that you’ve read the e-mail. And if it was spam, this will often earn you more spam since the spammers can tell you’ve read their last e-mail. But Google has just announced a move that will shut most of these tactics down: it will cache all images for Gmail users. Embedded images will now be saved by Google and the e-mail content will be modified to display those images from Google’s cache, instead of from a third party server. E-mail marketers will no longer be able to get any information from images—they will see a single request from Google, which will then be used to send the image out to all Gmail users. Unless you click on a link, marketers will have no idea the e-mail has been seen. While this means improved privacy from e-mail marketers, Google will now be digging deeper than ever into your e-mails and literally modifying the contents. If you were worried about e-mail scanning , this may take things a step further. However, if you don’t like the idea of cached images, you can turn it off in the settings.

Ukranian fraudster and CarderPlanet “Don” finally sentenced to 18 years

401(K) 2012 In 2001, a group of 150 Russian-speaking hackers gathered at a restaurant in Odessa to found CarderPlanet . It ultimately became one of the world’s most notorious fraudulent credit card data websites, and it was shut down in 2004 . On Thursday, one of the site’s founders, Roman Vega (aka “Boa”), was sentenced to 18 years in prison by a United States federal judge. Vega’s case has been going on for quite some time. The Ukrainian credit card fraudster was arrested, prosecuted, and convicted in Cyprus in 2003. Then, he was brought to the United States in 2004 to face federal charges in California, to which he pleaded guilty. By 2007, Vega faced fresh charges in New York. By early 2009, Vega pleaded guilty to those charges, but then he attempted to withdraw his plea in 2011. Various motions were filed, but by May 2012, the judge denied his request and his plea stood.

Valve: First version of SteamOS to be released to the masses on Friday

Valve PC gamers who are champing at the bit to build their very own ” Steam Machines ” won’t have to wait long to start tinkering, as Valve has revealed that its recently announced SteamOS will be available this Friday. The announcement comes alongside word from Valve that its prototype Steam Machines , along with the companion Steam Controller , will be shipped out to 300 randomly selected US beta testers on Friday. Valve plans to notify the lucky testers via e-mail at 2 pm Pacific today, and beta participants will get a special badge on their Steam accounts so journalists and fellow players can start bugging them for their impressions incessantly. If you’re not part of that lucky group of 300, though, you’re probably more interested in the fact that “SteamOS will be made available when the prototype hardware ships… downloadable by individual users and commercial OEMs.” More information about that release is coming soon, the company says, but Valve is already warning that “unless you’re an intrepid Linux hacker already, we’re going to recommend that you wait until later in 2014 to try it out.” Read 2 remaining paragraphs | Comments

AT&T offers gigabit Internet discount in exchange for your Web history

AT&T is watching you browse. Seth Anderson AT&T’s “GigaPower” all-fiber network has launched in parts of Austin, Texas, with a price of $70 per month for download speeds of 300Mbps (which will be upgraded to a gigabit at no extra cost in 2014). The $70 price is only available if you agree to see targeted ads from AT&T and its partners, however. Interestingly, AT&T labels the Internet service with targeted ads as its “premier” service while calling the service without targeted ads “standard.” Not only is the price of the premier service (with ads) only $70 a month, but it comes with a waiver of equipment, installation, and activation fees. The standard service without ads is $99 a month, and there’s no mention of a waiver in AT&T’s announcement . “The waiver is part of the Premier package, so is not available with the standard service at this time,” AT&T told Ars.
