Comment Consumer Friendly?! Why "Open Source" Tag? (Score 5, Informative) 319

I read through the article and a lot of blogs covering Riversimple. Here's what it looks like under the hood. It seems too early and preliminary for adoption. "Open Source" seems to have been employed purely as a buzzword to generate interest. Most of the detail is actually at the 40 Fires foundation website which will probably release design schematics. Their FAQ answers questions I had in mind and is a good place for a starting read. The codename for this car is Hybran. The EU welcomes Hydrogen cars as a strong "Green" alternative.

If you do compare it to other initiatives like OSCar, you would find this option from Riversimple probably at a better stage of adoption. But until they unveil their prototypes (16-Jun-2009 is not far) and manufacturing goals (however they intend to go about it,) consumers will be skeptical about adoption. They first have to hit a note on consumers _wanting_ it or _needing_ it before proposing an attractive business model. Most of the prior comments reflect that we are not yet ready. Design momentum on OSCar seems to have stalled in the year 2006.

In contrast another vehicle release earlier this year happened in India with a lot of buzz about a $2,500 car, the Nano from India. This car _can_ do more than 56 mpg on Gasoline. It isn't green, but you can grab one, drive one and feel much safer than the electric counterparts that roam about the cities. This car went through at least 2 yrs of testing because the average consumer was scared about safety. The adoption was further slowed down by slow manufacturing response from Tata Motors.

India has allowed an Electric car (REVA) to be used within City limits (for road safety and range concerns) manufactured by Reva. The vehicle (a modest 4 wheeler) which comes in multiple flavors has low adoption rates in cities which allow it. This car through evolution has been heavier than India's top selling gasoline small-car the Maruti Suzuki 800cc 4 seater, and offers lesser range within a city. It has a very short range of 80-100km and requires battery packs to be replaced every two years (or depending on usage.) From June, 2001 the adoption has been very slow. During July, 2008 at least 260 Reva's (multiple models) were sold which is a record high. The Reva is priced at a one time price tag of close to $6,500 with an installed set of batteries. These have to be replaced at about $1000 every year. There's some comprehensive information and links on the Wikipedia Article (Reva). The cost has been a factor in slowing down adoption added to the fact that electric charges are required almost on a nightly basis. India has welcomed the car with reduced parking charges and several cuts. The G-Whiz model sold outside India is far too pricey ($12000 in Chile) and does not enjoy these environment friendly regulatory benefits.

For crowded cities in India where pollution is a heavy problem, Electrical cars with limited range for office commuters who'd prefer some shade (where public transport is a little inconvenient with timings) has received early adoption. i would presume that countries facing rapid development and growth rates will have to take this more seriously. Scaling public transport infrastructure has always been a challenge in many developing countries owing to a myriad of reasons. The basis for creating indices to track air pollution is outlined quite well in this paper (PDF) from IOP.

As many earlier comments point out accurately, adoption of such alternatives will require regulatory laws from the government (Road taxation, Commercial tax holidays, Green Credits and a lot more.) The working business model for Leasing automobiles is already here. The period being talked about (20yrs) might need to be tweaked which is presumably because of high manufacturing and deployment costs on low initial volume.

There are some pitfalls of lightweight cars at an early stage. Their ride heights are incredibly low that restricts markets in which they can be adopted. It might even keep them out of developing countries until the designs are tested. IMHO coming up with a disruptive solution to personal transport and tagging it with another 20yr lease agreement without the support of an auto major who's made it over a decade selling small cars or energy efficient cars is asking too much from the consumer. The "Open Source" tag means too little unless auto manufacturers see this as the best way to go forward.

Student Who Released Code From Assignments Accused of Cheating 333

Death Metal sends in a story about Kyle Brady, a computer science major at San Jose State University, who recently ran into trouble over publishing the source code to his programming assignments after their due dates. One of Brady's professors contacted him and threatened to fail him if he did not take down the code. Brady took the matter to the Computer Science Department Chair, who consulted with others and decided that releasing the code was not an ethical violation. Quoting Cory Doctorow at Boing Boing: "There's a lot of meat on the bones of this story. The most important lesson from it for me is that students want to produce meaningful output from their course-assignments, things that have intrinsic value apart from their usefulness for assessing their progress in the course. Profs — including me, at times — fall into the lazy trap of wanting to assign rotework that can be endlessly recycled as work for new students, a model that fails when the students treat their work as useful in and of itself and therefore worthy of making public for their peers and other interested parties who find them through search results, links, etc. But the convenience of profs must be secondary to the pedagogical value of the university experience — especially now, with universities ratcheting up their tuition fees and trying to justify an education that can put students into debt for the majority of their working lives."

Open Source Car — 20 Year Lease, Free Fuel For Life 319

ruphus13 writes "The race for a hyper-fuel-efficient car is on in a big way. Now, Riversimple has tried to leverage the knowledge of the masses to bring its vision to reality soon with a car that gives the equivalent of 300 miles to the gallon. 'The idea to build an open source car isn't a new one, but you've got to give vehicle design company Riversimple credit for originality. The company plans to unveil its first car in London later this month, a small two-seater that weighs roughly 700 pounds. If you agree to lease one for 20 years (yes, 20), Riversimple will throw in the cost of fuel for the lifetime of the lease...The team decided to release the car's designs under an open source license in order to speed up the time it takes to develop the vehicle while also driving down the cost of its components.'"

Submission + - Airport Security, Paranoia and Convenience 1

betasam writes: "US Homeland security, in an effort to make "screening" faster came up with this millimeter ray scanning device. This looks like the full body scan from "Total Recall". Most people who are concerned about their privacy have objected to airport security body scans. There are claims that the scanner is "remotely reviewed" by a person who 'cannot' view the face of the person being scanned. That doesn't make people feel any safer. You could find an earlier British prototype showing the use of a full body scanner. Here is news of installation of such a device at Heathrow. This body scanner looks identical to the newer one.

I see another Slashdot story which shows an anti-hijacking safety bracelet. There was a 1976 patent following the 1972 Munich games by a Singapore Inventor Sai Kheong Kwan and a former Vice-Chancellor of the National University of Singapore. This is literally a handcuff which didn't make it. Governments are taking monitoring for security too serious and are probably not as well prepared in counter-measures. The inconvenience is weighing far too heavily against the advantages."

Submission + - IIS 6 Attack Could Let Hackers Snoop On Servers (infoworld.com)

snydeq writes: "A flaw in the way that Microsoft's software processes Unicode tokens has been found to give attackers a way to view protected files on IIS Web servers without authorization. The flaw, exposed by Nikolaos Rangos, could be used to upload files as well. Affecting IIS 6 users who have enabled WebDAV for sharing documents via the Web, the vulnerability is currently being exploited in online attacks, according to CERT, and is reminiscent of the well-known IIS unicode path traversal issue of 2001, one of the worst Windows vulnerabilities of the past decade."

Comment Hyperspace from Phoenix (Score 2, Interesting) 3

I did check out Hyperspace quite some time back when they were looking for developers to extend it further. It seems to be a remix of the Xen hypervisor, though heavily modified and possibly derived from a Citrix license. The idea is to provide what Borland managed to do with Sidekick and it isn't a product that is meant to just sit in the BIOS. Phoenix's Download page clearly shows that Hyperspace is an individual software product that can be bought. I'd certainly love to have a Sidekick like option today and an in-built paravirtualization module to switch between different kernels or Operating Systems without a reboot. This seems promising, although consumer adoption will probably be kicked in through OEMs more than Software Box sales.

Submission + - Phoenix BIOSOS? (technologyreview.com) 3

jhfry writes: An interesting development by an unexpected source, Phoenix Technologies is releasing a Linux based, virtualization enabled, BIOS based OS for computers (Technology Review). They implemented a full Linux distro right on the BIOS chips, and using integrated virtualization technology it "allows PCs and laptops to hot-switch between the main operating system, such as Windows, and the HyperSpace environment." So essentially they are "trying to create a new market using the ideas of a fast-booting, safe platform that people can work in, but remain outside of Windows."

Comment Chromium on Linux, no Chrome? (Score 1) 258

Why would Google put all the effort and keep their browser running on Windows with their own linux port being delayed? I have a pet theory to that. Google did in fact sponsor adoption of firefox and provided lots of plugins. Many of us *know* firefox can be a resource hog and also slower at rendering than many, we have few HTML rendering engines that can render most content. I believe that Google is abstaining from releasing a competitor to firefox on Linux platforms for some reason. The "Chrome" and "Chromium" stories are going to stay that way for a while until they have good reasoning to go native. They would still something similar to what they have done with Picasa (integrated wineserver approach.) It has worked before. So Chrome/Linux will be very similar to Chromium.
