The Sounds of Tech Past 231

itwbennett writes "If you're of a certain generation, the screech of a modem, the stuttering song of the dot matrix printer, and the wet slap of a mimeograph machine can transport you to simpler (or at least slower) times. JR Raphael has rounded up 20 tech sounds on the brink of extinction for your listening torture. We're only sorry we don't have smell-o-vision to bring you that sweet mimeograph scent."

3D Printer Models For Universal Construction Toy Connectors 76

dangle writes "F.A.T. Lab and Sy-Lab have officially released their Free Universal Construction Kit, allowing builders to freely interconnect parts from Lego, K'Nex, Fischertechnik, and other common building sets. ZomeTool and Zoob patterns will be available after related patents expire. The makers have also spent considerable effort investigating and anticipating legal complaints from manufacturers, using an Inverse Think of The Children Argument: Some may express concern that the Free Universal Construction Kit infringes such corporate prerogatives as copyright, design right, trade dress, trademarks or patents of the supported toy systems. We encourage those eager to enforce these rights to please think of the children — and we assert that the home printing of the Free Universal Construction Kit constitutes protected fair use." Model files are available over at Thingiverse. The designs are all covered by the CC BY-SA 3.0.

HP To Combine PC, Printer Divisions 142

itwbennett writes "Apotheker wanted to sell off HP's PC division, Whitman vowed not to, and now HP is combining the PC division with the printer division in an effort to cut costs, unnamed sources told the All Things D blog. Given that both divisions reported declining sales last quarter, is HP hoping that two wrongs make a right?"

The Laser Unprinter 168

MrSeb writes "You've heard of laser printers — and now a team of researchers from the University of Cambridge in England has created a laser unprinter that can remove ink without damaging the paper. Despite both methods using lasers, their (un)printing approaches are fundamentally very different. In a laser printer, a laser is used to give individual 'pixels' on a piece of paper a positive charge (a separate heat source is used to fuse toner). In the laser unprinter, picosecond pulses of green laser light are used to vaporize the toner, or ablate in scientific terms. The primary goal of unprinting is to cut down on the carbon footprint of the paper and printing industries. Manufacturing paper is incredibly messy business, with a huge carbon footprint. Recycling paper is a good step in the right direction, but it still pales in comparison to unprinting. In a worst-case scenario, The University of Cambridge unprinting method has half the carbon emissions of recycling; best-case, unprinting is almost 20 times as efficient."

Nanoscale Race Car Gets 3D Printed With a Laser 39

An anonymous reader writes "Researchers at the Vienna University of Technology have managed to perfect 3D printing at the nanoscale. What may look like a grain of sand to the human eye could in fact be a detailed racing car model, a reproduction of a famous church, or London Bridge. The 3D printer relies on a laser beam directed by mirrors through a liquid resin onto a surface. It can print at 5 meters per second, which is a world record, and the end result is only a few hundred nanometers in size. The next hurdle: printing with bio-material so we can start making our own body parts/organs."

Torvalds Calls OpenSUSE Security 'Too Intrusive' 311

jfruh writes "The balance between security and ease of use is always a tricky one to strike, and Linux distros tend to err on the side of caution. But no less a luminary than Linus Torvalds thinks openSUSE has gone too far. When his kid needed to call from school for the root password just so he could add a printer to a laptop, that's when Linus decided things had gone off the rails."

With Push for OS X Focus, CUPS Printing May Suffer On Other Platforms 267

CUPS is the popular open-source printing system that many projects have used successfully as a core, for desktop printing and as the basis of dedicated print servers. Reader donadony writes with word that Apple "has chosen to abandon certain Linux exclusive features, [while] continuing with popular Mac OS X features. The changeover is being attempted by Apple to set new printing standards that will not require 'drivers' in the future." However, as this message from Tim Waugh at Red Hat points out, all is not lost: "Where they are of use for the Linux environment, those orphaned features will continue to be maintained at OpenPrinting as a separate project."

FOIA Request Shows Which Printer Companies Cooperated With US Government 355

New submitter Dave_Minsky writes "The U.S. Secret Service responded to a FOIA request on Monday that reveals the names of the printer companies that cooperate with the government to identify and track potential counterfeiters. The Electronic Frontier Foundation revealed in 2005 that the U.S. Secret Service was in cahoots with selected laser printer companies to identify and track printer paper using tiny microscopic dots encoded into the paper. The tiny, yellow dots — less than a millimeter each — are printed in a pattern over each page and are only viewable with a blue light, a magnifying glass or a microscope. The pattern of dots is encodes identifiable information including printer model, and time and location where the document was printed." Easy enough to avoid government dots; just don't buy printers from Canon, Brother, Casio, HP, Konica, Minolta, Mita, Ricoh, Sharp, or Xerox.

Best Practice: Travel Light To China 334

Hugh Pickens writes "What may once have sounded like the behavior of a raving paranoid is now considered standard operating procedure for officials at American government agencies, research groups and companies as the NY Times reports how businesses sending representatives to China give them a loaner laptop and cellphone that they wipe clean before they leave and wipe again when they return. 'If a company has significant intellectual property that the Chinese and Russians are interested in, and you go over there with mobile devices, your devices will get penetrated,' says Joel F. Brenner, formerly the top counterintelligence official in the office of the director of national intelligence. The scope of the problem is illustrated by an incident at the United States Chamber of Commerce in 2010 when the chamber learned that servers in China were stealing information from four of its Asia policy experts who frequently visited China. After their trips, even the office printer and a thermostat in one of the chamber's corporate offices were communicating with an internet address in China. The chamber did not disclose how hackers had infiltrated its systems, but its first step after the attack was to bar employees from taking devices with them 'to certain countries,' notably China. 'Everybody knows that if you are doing business in China, in the 21st century, you don't bring anything with you,' says Jacob Olcott, a cybersecurity expert at Good Harbor Consulting. 'That's "Business 101" — at least it should be.'"

83-Year-Old Woman Gets New 3D-Printed Titanium Jaw 121

arnodf writes "The University of Hasselt (in Belgium) announced today (Google translation of Dutch original) that Belgian and Dutch scientists have successfully replaced an 83-year-old woman's lower jaw with a 3D-printed model. According to the researchers, 'It is the first custom-made implant in the world to replace an entire lower jaw. ... The 3D printer prints titanium powder layer by layer, while a computer controlled laser ensures that the correct particles are fused together. Using 3D printing technology, less materials are needed and the production time is much shorter than traditional manufacturing. The artificial jaw is slightly heavier than a natural jaw, but the patient can easily get used to it."

Ask Slashdot: Wireless Proximity Detection? 101

New submitter Cinnamon Whirl writes "As a chemist, I work in a both lab and office enviroments, and need access to data in both, without causing undue clutter in either. My company has recently purchased two Win7 tablets for trial usage with electronic lab notebooks, propietry software, SAP, email etc. These are also useful for sharing in meetings, etc. As part of this project, I have been wondering whether we can use these tablets to detect other devices by proximity. Examples could include finding the nearest printer or monitor or, perhaps trickier, could two roaming devices find each other? Although lab technology is rarely cutting edge, I can see a day when all our sensors and probes will broadcast data (wireless thermocouples are already available), and positioning information will become much more important. What technologies exist to do this? How accurate can the detection be?"

Pirate Bay To Offer Physical Item Downloads 343

lukehopewell1 writes "The Pirate Bay is offering users the chance to download and print out real objects using 3D printers in what the pirate site is hailing as 'the future.'" Amir Taaki mentions that among the new "physibles" uploaded to the Pirate Bay are "plans for a tabletop replica for a Warhammer 40k dreadnought that got taken down in December with a DMCA request." Downloadable 3D models have been around for a while; MakerBot users are probably all familiar with the Thingiverse. Couple TPB with a cheap method of accurate 3D scanning, though, and I wonder what illegal shapes will emerge.

US Chamber of Commerce Infiltrated By Chinese Hackers 173

SpzToid writes "The Wall Street Journal is now reporting that a group of hackers in China breached the computer defenses of the United States Chamber of Commerce. The intrusion was quietly shut down in May 2010, while FBI investigations continue. 'A spokesman for the Chinese Embassy in Washington, Geng Shuang, said cyberattacks are prohibited by Chinese law and China itself is a victim of attacks. ... Still, the Chamber continues to see suspicious activity, they say. A thermostat at a town house the Chamber owns on Capitol Hill at one point was communicating with an Internet address in China, they say, and, in March, a printer used by Chamber executives spontaneously started printing pages with Chinese characters.'" According the article, the group "gained access to everything stored on its systems" and may have "had access to the network for more than a year before the breach was uncovered."

How 3D Printing Could Help Keep the ISS In Orbit 200

Despite all the best intentions and meticulous overengineering, some of the equipment on spacecraft like the ISS inevitably breaks. An anonymous reader poses the question "Why carry out a very expensive launch into space to resupply the ISS, when astronauts could just manufacture replacement parts themselves?" Startup Made in Space is working on a space-oriented 3D printing system to make it easy to transmit the information needed to pop out complex shapes (as might be in delicate mechanical systems), but the founders are also talking about using 3D printers to jump-start construction if humans extend their presence from the Earth to other planets (or revisit the moon).

A little background: With my laptop being four years old, and the battery failing, I want to replace it with a device with 10 hours of battery. I am purchasing an Asus Transformer Prime after Christmas as a gift to myself; my plan is to replace my laptop completely for portable computing. I've already selected several apps that should meet my needs, including Polaris Office, and TeamViewer to remotely access my desktop. So are there any printing solutions for Android? Printing to my network printer at home is good enough."

Printers Could Be the Next Attack Vector 175

New submitter rcoxdav writes "Researchers have found that the upgradeable firmware on some laser printers can be easily updated and compromised. The updated firmware could then be used to do anything from overheating the printer to compromising a network. Quoting: 'In one demonstration of an attack based on the flaw, Stolfo and fellow researcher Ang Cui showed how a hijacked computer could be given instructions that would continuously heat up the printer’s fuser – which is designed to dry the ink once it’s applied to paper – eventually causing the paper to turn brown and smoke. In that demonstration, a thermal switch shut the printer down – basically, causing it to self-destruct – before a fire started, but the researchers believe other printers might be used as fire starters, giving computer hackers a dangerous new tool that could allow simple computer code to wreak real-world havoc.'"

Palantir, the War On Terror's Secret Weapon 276

hessian tips a story in BusinessWeek about Palantir, a system designed to aggregate disparate data points gathered by intelligence agencies and weave them into a more useful narrative. The article summarizes it thus: "Depending where you fall on the spectrum between civil liberties absolutism and homeland security lockdown, Palantir’s technology is either creepy or heroic." "The day Fikri drives to Orlando, he gets a speeding ticket, which triggers an alert in the CIA's Palantir system. An analyst types Fikri's name into a search box and up pops a wealth of information pulled from every database at the government's disposal. There's fingerprint and DNA evidence for Fikri gathered by a CIA operative in Cairo; video of him going to an ATM in Miami; shots of his rental truck's license plate at a tollbooth; phone records; and a map pinpointing his movements across the globe. All this information is then displayed on a clearly designed graphical interface that looks like something Tom Cruise would use in a Mission: Impossible movie."
