Mandrill warned customers on Wednesday that some email-related data may have been exposed after attackers tried to lasso some of its servers into a botnet.Data doesn’t appear to have been stolen, but some customers should take some security precautions, wrote Brandon Fouts, general manager of Mandrill, which is a platform for managing transactional email that is owned by The Rocket Science Group.“There’s not evidence that any customer data was queried or exported, but unfortunately we can’t completely rule out the possibility of access,” Fouts wrote in a blog post.Data that may have been exposed includes internal logs about emails sent, including sender and recipient addresses but not custom metadata or the content of messages, Fouts wrote.To read this article in full or to leave a comment, please click here

T-Mobile CEO ‘fairly confident’ net neutrality won’t kill Music Freedom

T-Mobile’s CEO says he’s confident that upcoming net neutrality rules won’t mean an end to the carrier’s “Music Freedom” promotion that allows unrestricted music streaming from certain sites.The rules, which were recently approved by the Federal Communications Commission but are not yet law, prohibit Internet providers from selectively blocking or slowing Web traffic and from offering paid traffic prioritization services. They’ve been opposed by Republican lawmakers and major telecommunications companies.John Legere said he’s still combing through the 400-page regulation, which the FCC passed after an unprecedented 4 million [m] public comments, but he doesn’t believe the service will be affected.To read this article in full or to leave a comment, please click here

Cumulus Networks, sFlow and data center automation

The Cumulus Linux platform makes it possible to run the same open source agent on switches, servers, and hypervisors – providing unified end-to-end visibility across the data center. The open networking model that Cumulus is pioneering offers exciting opportunities. Cumulus Linux allows popular open source server orchestration tools to also manage the network, and the combination of real-time, data center wide analytics with orchestration make it possible to create self-optimizing data centers.

Install and configure Host sFlow agent

The following command installs the Host sFlow agent on a Cumulus Linux switch:

sudo apt-get install hsflowd

Note: Network managers may find this command odd since it is usually not possible to install third party software on switch hardware. However, what is even more radical is that Cumulus Linux allows users to download source Continue reading

Ideovitra seeks to slay PC power vampires with SensyBee smart switch

There’s a vampire-slayer stalking the halls at Cebit.With SensyBee, a curvy little box that plugs into the back of a PC between the power supply and the wall outlet, turning the PC off when it is unused, Ideovitra hopes to eliminate PCs’ vampire power consumption.A typical desktop PC consumes around 200 watts when running—but still as much as 50W when in Windows 8’s “sleep” mode. Even when “turned off,” it can consume up to 20W, as the power supply and some other components remain powered up to perform functions such as wake-on-LAN, said Ideovitra’s sales manager David Chedotal.In the 6,500 hours a year that the average office PC lies unused, that vampire power consumption can add between 130 and 325 kilowatt-hours to the energy bill. At German electricity prices, that’s anywhere from €30 (US$32) to €90 wasted each year, according to Ideovitra.To read this article in full or to leave a comment, please click here

Apple Watch and its wireless tech

Apple hasn't called its upcoming Apple Watch "magical" as it did with the iPad in 2010, but its wireless components have some spellbinding features.Whether the embedded NFC (near field communication), Bluetooth and Wi-Fi elements contribute to the success of the Apple Watch sales is still an open question. Fashion and an array of apps could definitely trump the device's wireless tech.Why might the wireless tech not matter?So far, there aren't many NFC-ready point-of-sale terminals installed in the U.S. Likewise, there are relatively few hotel rooms that can be unlocked with a Bluetooth connection to the Apple Watch.MORE ON NETWORK WORLD: 12 most powerful Internet of Things companies Wi-Fi access points and hotspots seem to be everywhere, but there is disagreement over how important Wi-Fi will be on the Apple Watch.To read this article in full or to leave a comment, please click here

Pixometer app offers a smarter way to read dumb meters

So you want to track your water, electricity or gas consumption, but you still don’t have a smart meter on your supply? Pixolus has a mobile app that makes it easier to keep track of meter readings, even with dumb meters. Just tell the Pixometer app which meter you’re going to read, point the phone’s camera at it, and let the optical character recognition software do the work. Once the app gets a lock on the numbers, it speaks the reading out loud and stores it, and the date, in that meter’s file. You can even enter the price per kilowatt-hour, for electricity, or per cubic meter, for water, and the app will show you the expenditure since the last meter reading, and what that works out to per month.To read this article in full or to leave a comment, please click here

Proposed data breach notification bill criticized as too weak

Proposed legislation that would require U.S. businesses to notify affected customers after data breaches is too weak because it would preempt stronger breach notification laws in several states and it wouldn’t cover several classes of data, including geolocation and health information, critics told lawmakers.The proposed Data Security and Breach Notification Act covers only data linked to identity theft or financial fraud, including Social Security numbers, but would not require businesses and nonprofit groups to notify users if other information is stolen, said critics, including Democratic members of the House of Representatives Energy and Commerce Committee’s trade subcommittee.To read this article in full or to leave a comment, please click here

After a security enthusiast discovered a loophole that allowed him to register a valid SSL certificate for Microsoft’s live.fi domain, he tried to responsibly disclose the issue.

Hailing 50 spectacular years of spacewalking

Space walkImage by REUTERS/NASA/Handout via ReutersIt had to be quite the rush. The first spacewalk, or extravehicular activity (EVA) happened March 18, 1965, when cosmonaut Alexei Leonov first departed the Soviet Union's Voskhod 2 spacecraft to test the idea – he stayed out about 10 minutes.   American Edward White II took the US’ first spacewalk that year in June stepping out of the Gemini IV spacecraft. Since that time many have taken the plunge outside the their spacecraft to fix problems, make adjustments and even hit a golf ball, as one NASA astronaut did in 2006 – he shanked it. Take a look at some of the milestones of spacewalking.To read this article in full or to leave a comment, please click here

Tim Cook on Steve Jobs and why Apple Watch will be the first smartwatch that matters

It's too soon to tell if Apple Watch will be a smash hit, but CEO Tim Cook said in a new interview that the new device “will be the first modern smartwatch—the first one that matters.”Cook told Fast Company that the company hasn’t put any sales expectations on the watch because the need for an iPhone 5, 5c, 5s, 6, or 6 Plus to work “creates a ceiling.”But the watch will be an important step forward for the industry, just as the iPod, iPhone, and iPad were, because it will create a new computing experience.MORE: 10 mobile startups to watch “The inputs that work for a phone, a tablet, or a Mac don’t work as well on a smaller screen,” Cook said. “Most of the companies who have done smartwatches haven’t thought that through, so they’re still using pinch-to-zoom and other gestures that we created for the iPhone.”To read this article in full or to leave a comment, please click here
