Part-Human, Part-Machine Transistor Devised 77

asukasoryu writes "Man and machine can now be linked more intimately than ever, according to a new article in the journal ACS Nano Letters. Scientists have embedded a nano-sized transistor inside a cell-like membrane and powered it using the cell's own fuel. To create the implanted circuit, the UC scientists combined a carbon nanotube transistor, lipid bilayer coating, ion pump, and ATP. The ion pump changes the electrical charge inside the cell, which then changes the electrical charge going through the transistor, which the scientists could measure and monitor."

Objective-C Enters Top Ten In Language Popularity 351

bonch writes "Objective-C has entered the top 10 of the Tiobe Programming Community Index. Last year, it was at #39. The huge jump is attributed to its use in iPhone and iPad development. C, of which Objective-C is a strict superset, has reclaimed the #1 spot from Java, which slides to #2. Tiobe also explains how it determines its rankings."

Atlantis Blasts Off On Final Mission 143

shuz writes "Space shuttle Atlantis lifted off today on its STS-132 mission to the International Space Station — the final flight for the venerable vehicle. The mission involves three spacewalks over 12 days (PDF), during which the team will replace six batteries on the port truss which store energy from solar panels on that truss, bolt on a spare space-to-ground Ku-band antenna, and attach a new tool platform to Canada's Dextre robotic arm." NASA has video of the historic launch and reader janek78 adds this quote from the mission summary: "Atlantis lifted off on its maiden voyage on Oct. 3, 1985, on mission 51-J. Later missions included the launch of the Magellan probe to Venus on STS-30 in May 1989, Galileo interplanetary probe to Jupiter on STS-34 in October 1989, the first shuttle docking to the Mir Space Station on STS-71 in June1995, and the final Hubble servicing mission on STS-125 in May 2009."

Exam Board Deletes C and PHP From CompSci A-Levels 663

VitaminB52 writes "A-level computer science students will no longer be taught C, C#, or PHP from next year following a decision to withdraw the languages by the largest UK exam board. Schools teaching the Assessment and Qualifications Alliance's (AQA) COMP1 syllabus have been asked to use one of its other approved languages — Java, Pascal/Delphi, Python 2.6, Python 3.1, Visual Basic 6, and VB.Net 2008. Pascal/Delphi is 'highly recommended' by the exam board because it is stable and was designed to teach programming and problem-solving."

Re-Purposing the Netherlands' Dike System For Power Generation 132

vikingpower writes "Built in reaction to a major flood that killed 1,800 in the '50s, the Dutch system of dikes, sluices, surge barriers, and dams has been dubbed 'one of the seven wonders of the modern world' by the American Society of Engineers. Now there are proposals to use the system differently, e.g. as tidal power plants, by punching holes in them. Any civil engineer's mouth will probably be watering when thinking of the mega-projects this could give rise to."

How Many Hours a Week Can You Program? 547

An anonymous reader writes "How many hours a week should a full-time programmer program? Trying to program anywhere near 40 wears me out. On a good week, I can do 20. Often, it is around 10 or 15. I'm talking about your programming session at the console, typing — including, of course, stopping and thinking for a minute, but not meetings, reading programming books, notes, specifications, etc., which by comparison feel like lunch breaks. I rarely get called to meetings (which is good) but that means to keep my brain from overheating I spend several hours a week surfing the web (usually reading tech news but also a few stops on Facebook, email, etc.). I should add that I am interrupted a few times per day. Me and another guy maintain an intranet site of a couple dozen web apps for an IT department, so we work on a few different things: phone calls, bug fixes, feature adds, as well as writing new web apps from the ground up, all in a day's work. And I know that wears a person out more than if they had just one project to work on. I wonder if programming is like mental sprinting, not walking, so you can only do it in bursts. Am I normal or stealing?"

The Pirate Party of Canada Is Official 430

wasme writes "The Pirate Party of Canada has become the first Pirate Party outside of Europe to become an official political party. Elections Canada confirmed with the party that the PPCA has gained 'eligible for registration' status, and can run in elections starting June 14. From the PPCA's official announcement: 'We are pleased to announce that as of April 12, 2010, the Pirate Party of Canada is officially eligible for Party Status. After 10 months of dedication and hard work, we have reached eligible status, which only leaves a 60-day "purgatory" period. After that, we will field candidates in subsequent federal elections, and begin the real work of a political party.'"

The Best, Worst, and Ugliest OSes of the Decade 378

itwbennett writes "Hundreds of Operating Systems were released during the past decade, finding their way into microdevices, watches, refrigerators, mobile phones, cars, motorcycles, jets, even the International Space Station. Some worked; some even worked well. Others, sadly, didn't. And some were just ahead of their time. Blogger Tom Henderson takes a look back at the best and worst OSes of the decade. Among the worst? Vista, as you'd suspect, along with WinME. But what about GNU Hurd? And some of the best? Solaris/OpenSolaris 10, Mac OS X, and newcomer Google Android."

After 8 Years of Work, Be-Alike Haiku Releases Official Alpha 411

NiteMair writes "The Haiku project has finally released an official R1 alpha, after 8 years of development. This marks a significant milestone for the project, and it also debuts the first official/publicly available LiveCD ISO image that can be easily booted and used to install Haiku on x86 hardware. Haiku is a desktop operating system inspired by BeOS after Be, Inc. closed its doors in 2001. The project has remained true to the BeOS philosophy while integrating modern hardware support and features along the way." Eugenia adds this link to an article describing the history of the OS, along with a review of the alpha version."

Comment Been in Baltimore for a while (Score 1) 863

These meters have been all around downtown Baltimore for a couple years now and while I agree that the round-trip to the ticket dispenser is annoying from an efficiency standpoint, it's still FAR better than coin meters if only for the sole reason that they take credit/debit cards. I don't keep change in my car (great way to get your car broken into in some parts). I haven't deliberately carried coins in my pockets for probably a decade.

The biggest problem I've had with the electronic meters is that you can't add time to an existing ticket. You have to either pay more in advance to 'make sure' you won't run out of time or you'll end up paying double for overlapping time. If I return back early and there's significant time remaining, I usually take the ticket back to the dispenser leaving it in the credit card slot or similar visible place so the next person can use it.

What do I really want? I'd like for people that touch my car while parallel parking to get an automatic citation. Let me decide whether to wave the fine or not. Hooking parking into the EZPass system would also be nice, so the parking spots know when I'm there, I'm automatically microbilled, and a ticket is no longer necessary.

Bike Projector Makes Lane For Rider Screenshot-sm 856

hh4m writes "Whether it's San Francisco, New York, or any bicyclistic city in between, you're destined to witness biker after biker dancing with danger, especially at night when visibility is uncomfortably low. Alex Tee and Evan Gant's LightLane device was recently just a concept but is soon to enter reality as a much-needed visual declaration of personal biking space. With a dire shortage of dedicated lanes, LightLane provides urban cyclists with a solution that adapts to them and any route they make take. The compact projector mounts easily to the rear of a bike frame and projects a bike lane-inspired linear pattern that provides great visibility and a familiarity that helps catch a driver's attention."

Comment Re:BRL-CAD, Emacs, and GCC for some perspective (Score 1) 66

It's not a big deal except to the PLplot devs as an arbitrary line being passed. Kudos to them for making ten thousand measured changes to their code, hope they make it to the next decimal place up. Probably not unlike the mild nod of appreciation you might feel when you hit 100,000.

It's a rather meaningless metric in general simply because there are massive differences in commit styles across projects and even within the same project. Even less meaningful than the meaningless lines-of-code metric. As an example, BRL-CAD's commits were almost universally 'huge' commits until it went open source. Then the more iterative 'chatter' commit style of most open source projects was adopted where they became much much smaller and considerably more frequent, communicating intent much better. Revision history that's actually useful! Even now, there are some devs that commit early, commit often, and others on the project that still have a tendency to commit big when left unchecked.
