Fused-filament is actually welding because the molten material is the same as the 'base' material. The real problem is shrinkage in going from melt to solid. The same problem occurs in 2-part polymers since they shrink as they both polymerize and cool. (They get bleep-ing HOT during the process!) Some of the other processes (selective UV curing, selective laser sintering) avoid that problem and produce much better surface quality but at the cost of even longer build times and extremely more expensive materials.

Submission + - Tesla Model S has hidden ethernet port, user runs Firefox on the 17" Screen (dragtimes.com) 1

Submitted by FikseGTS
FikseGTS writes: A Tesla Model S owner located a 4 pin connector on the left side of the Tesla Model S dashboard that turns out to be a disguised ethernet networking port. After crafting his owns patch cable to connect with the Tesla’s port, a networking connection was established between the Tesla Model S and a laptop computer.

The Model S is running a 100 Mbps, full duplex ethernet network and 3 devices were found with assiged IP addresses in the 192.168.90.0 subnet. Some ports and services that were open on the devices were 22 (SSH), 23 (telnet),53 (open domain), 80 (HTTP), 111 (rpcbind), 2049 (NFS), 6000 (X11). Port 80 was serving up a web page with the image or media of the current song being played. The operating system is modified version of Ubuntu using an ext3 filesystem. Using X11 it also appears that someone was able to somewhat run Firefox on both of the Model S screens.

Is a jailbroken Tesla Model S on the way?

Submission + - Nest Halts Sales of Nest Protect After Discovering Dangerous Flaw (thestar.com)

Submitted by fructose
fructose writes: It seems that the Nest Protect has a flaw in it's software that, under the right circumstances, could disable the alarm and not notify the owners of a fire. To remedy this flaw, they are disabling the Nest Wave feature through automatic updates. Owners who don't have their Nest Protects connected to their WiFi net or don't have a Nest account are suggested to either update the device manually or return it to Nest for a full refund. While they work out the problem, all sales are being halted to prevent unsafe units from being sold. There have been no reported incidents resulting from this flaw, but they aren't taking any chances. Considering the potential danger involved, I'd say this is a pretty safe move.

Submission + - Five Year Old uncovers XBOX ONE log in flaw. (bbc.co.uk)

Submitted by Smiffa2001
Smiffa2001 writes: The BBC are reporting that five-year-old Kristoffer Von Hassel from San Diego has uncovered a (frankly embarrassing) security flaw within the XBOX ONE log in screen. Apparently by entering an incorrect password in the first prompt and then filling the second field with spaces, a user can log in without knowing a password to an account.

Young Kristoffer's Dad has submitted the flaw to Microsoft — who have patched the flaw — and have generously provided four free games, $50, a year-long subscription to Xbox Live and an entry on their list of Security Researcher Acknowledgements.

Submission + - Wearables Are Already Wearing Out Their Welcome (itworld.com)

Submitted by itwbennett
itwbennett writes: In a new white paper based on an Internet survey of 'thousands of Americans', the consulting firm Endeavor Partners has concluded that wearables (at least in their current incarnation) may already be on their way out. The survey found that one-third of American consumers who have owned a wearable product stopped using it within six months. Meanwhile, eBay is rapidly filling with second-hand smartwatches: At the time of this writing, an eBay search turned up 2,465 results for 'Samsung Galaxy Gear'.

Submitted by Anonymous Coward
An anonymous reader writes: Article in latest issue of IEEE Security+Privacy has the estimate and lots of other juicy stuff (paywall, but original pdf here http://research.microsoft.com/...). Microsoft authors accuse industry of using O(N) solutions (where N is number of users) even when O(logN) or better solutions exist.

“We appear to have lost sight of the original goal. We are pursuing substitute goals, such as password complexity and expiration, as ends in themselves long after it has become clear that they do little for the original problem.”

Submission + - Exposure to Morning Sunlight Helps Managing Weight

Submitted by jones_supa
jones_supa writes: A new Northwestern Medicine study reports the timing, intensity and duration of your light exposure during the day is linked to your weight — the first time this has been shown. People who had most of their daily exposure to even moderately bright light in the morning had a significantly lower body mass index (BMI) than those who had most of their light exposure later in the day, the study found. It accounted for about 20 percent of a person’s BMI and was independent of an individual’s physical activity level, caloric intake, sleep timing, age or season. About 20 to 30 minutes of morning light is enough to affect BMI. The senior author Phyllis C. Zee rationalizes this by saying that light is the most potent agent to synchronize your internal body clock that regulates circadian rhythms, which in turn also regulate energy balance. The study was small and short. It included 54 participants (26 males, 28 females), an average age of 30. They wore a wrist actigraphy monitor that measured their light exposure and sleep parameters for seven days in normal-living conditions. Their caloric intake was determined from seven days of food logs. The study was published April 2 in the journal PLOS ONE. Giovanni Santostasi, a research fellow in neurology at Feinberg, is a co-lead author.

Submission + - Reversible USB Cables That Will Make Life Easier: First Pictures (ibtimes.co.uk)

Submitted by concertina226
concertina226 writes: The USB Implementers Forum, which oversees the Universal Serial Bus specification, announced plans to develop a new USB standard in December to replace the current microUSB standard, almost universally used to power smartphones and tablets today.

"The specification is anticipated to be completed in July 2014. We could see products with the new cable by end of year," the USB IF told CNET at the Intel Develop Forum conference in Shenzhen, China.

The new Type-C cables will run on the USB 3.1 standard, which supports 10Gbps transfer rates, although the USB prong itself will measure 8.3mm x 2.5 mm, which is slightly smaller than the common USB cable ports in PCs but slightly larger than the microUSB cables used to connect mobile phones.

Submission + - Converter Makes JSON as Understandable as a Spreadsheet (programmableweb.com)

Submitted by CowboyRobot
CowboyRobot writes: Eric Mill, a developer at the Sunlight Foundation, has created a JSON-to-CSV converter where users can simply paste JSON code into a box and have the code automatically reformatted and re-colored, then converted into an easily readable table of data. A complete CSV of the table data can also be downloaded. The converter uses JavaScript so it runs without a server and the JSON conversions happen inside the browser.

Submission + - Council dumps Microsoft Windows XP for Google Chromebooks, saves £400,000 (v3.co.uk)

Submitted by girlmad
girlmad writes: Google has scored a major win on the back of Microsoft’s Windows XP support cut-off. The London Borough of Barking and Dagenham has begun moving all its employees over to Samsung Chromebooks and Chromeboxes ahead of the 8 April deadline. The council was previously running 3,500 Windows XP desktops and 800 XP laptops, and is currently in the process of retiring these in favour of around 2,000 Chromebooks and 300 Chromeboxes. It estimates the savings at around £400,000, no small change.

Submission + - What THE FUCK is up with autoplay on story pages? 2

Submitted by ScuzzMonkey
ScuzzMonkey writes: I'm not here often enough to bitch about all the other poorly-considered site changes that are apparently in the works, but the autoplay audio summary? Not cool. Maybe this is the April Fools Joke this year, I don't know, but if so, it's not funny, particularly with no readily apparent means of disabling it.

If there is nothing else showing how much this site is changing for the worse under new management, there you go. There are some transgressions that every geek knows to be verboten. Audio playing automatically when you hit a web page is one of them. Bring on the blink tags if you want to try for retro funny.

Submission + - Supreme Court skeptical of computer-based patents (usatoday.com)

Submitted by walterbyrd
walterbyrd writes: The case, Alice Corp. v. CLS Bank International, poses huge risks for both sides. If the court upholds the patent or rules only narrowly against it without affecting most others, the problem of too many patents — and patent lawsuits — will continue. In that case, Justice Stephen Breyer said, future competition could move from price and quality to "who has the best patent lawyer."
