Transistor Made From Cotton Yarn 92

MrSeb writes "Altering the very fabric of technophilic society, a multinational team of material scientists have created electric circuits and transistors out of cotton fibers (abstract). Two kinds of transistor were created: a field-effect transistor (FET), much like the transistors found in your computer's CPU; and an electrochemical transistor, which is similar but capable of switching at lower voltages, and thus better suited for wearable computers. Cotton itself is an insulator, but by using various coatings, the team from Italy, France, and the United States was able to make conductor and semiconductor cotton 'wires' that retained most of their flexibility. The immediate use-cases are clothes with built-in sensors (think radiation or heartbeat monitors), but ultimately, think of how many thousands of interconnections are in every piece of cotton clothing — you could make a fairly powerful computer!"

Ask Slashdot: Best Android Tablet For Travel? 356

PerlJedi writes "I am planing a long trip (to Ireland), and want to buy an Android tablet to take along for the trip. I am a software engineer (I actually work for Slashdot), a Linux geek, and an Android fan. I would like to get a tablet primarily to use for entertainment (when I'm not working or building robots in my workshop, I'm usually playing with my phone), but something I could get some work done from in a pinch would be a major plus (all I need to be able to work is a Web browser, and an ssh terminal, preferably with a keyboard). My current cell phone is the Samsung Charge, rooted and running GummyCharge 2.1, and it is a good bet I'll want to root whatever tablet I get, if not right away, soon after getting it. From an entertainment standpoint I want something that is large enough to watch high definition videos on, with a battery life that will make it practical for use on a long flight. Having a decent camera would be a nice plus, but is not an absolute necessity. Having a forward facing camera for video chat would also be good, but is also not a necessity." PerlJedi's got a few options in mind; read on for the details of his reasoning and help him fulfill his quest.

We plan on releasing the updates that will allow you to unlock your bootloader in the coming months.' However, they do note this: 'It is our responsibility to caution you that not all claims resulting or caused by or from the unlocking of the bootloader may be covered under warranty,' and this: 'We strongly suggest that you do not unlock the bootloader unless you are confident that you understand the risks involved.' This looks like a new year gift to some."

Prospects Darken For Solar Energy Companies 435

Hugh Pickens writes "Although global demand for solar power is still growing — about 8% more solar panels will be installed this year compared with 2010 — bankruptcies, plummeting stock prices and crushing debt loads are calling into question the viability of the solar energy industry that since the 1970s has been counted on to advance the world into a new energy age. Only a handful of manufacturers are now profitable in the face of too much capacity, which has contributed to a plunge in prices as government subsidies have been curbed. Prices for solar panels started 2011 near $1.60 per watt, but a buildup of inventory forced manufacturers into a fire sale toward the end of the second quarter that has pushed prices to near $1 per watt now. 'The prices that we're seeing today are likely not covering manufacturing costs in many cases,' says Ralph Romero. With at least seven solar-panel manufacturers filing for bankruptcy or insolvency in the last several months and six of the 10 largest publicly traded companies making solar components reporting losses in the third quarter, public-market investors are punishing the solar sector, sending shares down nearly 57% this year. Although winners are expected to emerge eventually, the question is how much more carnage there will be before that happens. 'The fact of the matter is, nobody really knows which solar companies will be pushed out of business or be forced to merge,' writes industry analyst Rodolfo Avalos. 'Nobody also knows how long it will take for the solar industry to improve even when the forecasted solar global demand for the next 5-10 years is quite promising.'"

Intel Medfield SoC Specs Leak 164

MrSeb writes "Specifications and benchmarks of Intel's 32nm Medfield platform — Chipzilla's latest iteration of Atom and first real system-on-a-chip oriented for smartphones and tablets — have leaked. The tablet reference platform is reported to be a 1.6GHz x86 CPU coupled with 1GB of DDR2 RAM, Wi-Fi, Bluetooth, and FM radios, and an as-yet-unknown GPU. The smartphone version will probably be clocked a bit slower, but otherwise the same. Benchmark-wise, Medfield seems to beat the ARM competition from Samsung, Qualcomm, and Nvidia — and, perhaps most importantly, it's also in line with ARM power consumption, with an idle TDP of around 2 watts and load around 3W."

DigiTimes Lends Credence To Apple-Branded TVs For 2012 232

It's a rumor that goes back years (here's one example from this summer) that Apple is planning to produce dedicated TV sets branded with its own name; the main question seems to be when. DigiTimes (hat tip to CNet) is reporting that component-maker sources say that Apple has begun the process by ordering parts that hint at an offering next year of Apple TV sets (as opposed to Apple TV) in 32" and 37".

Report Condemns Japan's Response To Nuclear Accident 267

mdsolar sends this quote from an article at the NY Times: "From inspectors who abandoned the Fukushima Daiichi nuclear power plant as it succumbed to disaster to a delay in disclosing radiation leaks, Japan's response to the nuclear accident caused by the March tsunami fell tragically short, a government-appointed investigative panel said on Monday. ... In particular, an erroneous assumption that an emergency cooling system was working led to an hours-long delay in finding alternative ways to draw cooling water to the plant, the report said. All the while, the system was not working, and the uranium fuel rods at the cores were starting to melt."

What If Babbage Had Succeeded? 212

mikejuk writes "It was on this day 220 years ago (December 26 1791) that Charles Babbage was born. The calculating machines he invented in the 19th century, although never fully realized in his lifetime, are rightly seen as the forerunners of modern programmable computers. What if he had succeeded? Babbage already had plans for game arcades, chess playing machines, sound generators and desktop publishing. A Victorian computer revolution was entirely possible."

Ask Slashdot: Best Kit For a Home Media Server? 355

First time accepted submitter parkejr writes "I started off building a media library a few years ago with an old PC running Ubuntu. Folders for photos, ogg vorbis music from my CD collection, and x264 encoded mkv movies. I have a high spec machine for encoding, but over the years I've moved the server to a bigger case, with 8 TB of disk capacity, and reverted back to Debian, but still running with the same AMD Sempron processor and 2GB RAM. It's working well, it's also the family mail server, and the kids are starting to use it for network storage, and it runs both link and twonkyserver, but my disks are almost full, and there are no more internal slots. The obvious option to me is to add in a couple of SATA PCI cards, to give me 4 more drives, and buy an externally powered enclosure, but that doesn't feel very elegant. I'm a bit of an amateur, so I'd like some advice. Should I start looking at a rack system? Something that can accommodate, say, 10 3.5" drives (I'm thinking long term, and some redundancy)? Also, what about location — I could run some cat6 to the garage and move it out of the house, in case noise is an issue. Finally, what about file format, file system, and OS/software? I'm currently running with ext3 and Debian Squeeze. Happy with my audio encoding choice, but not sure about x264 and mkv. I'd also consider different media server software, too. Any comments appreciated."

Ask Slashdot: Best Inexpensive VPS Provider? 375

David Greene writes "After many years of waiting for my provider to upgrade DSL service from the measly 1.5 Mbps I have now, I've decided to go another route. Unfortunately, no other provider in the area (Twin Cities) offers static IPs and permission to run servers. I am looking for a VPS solution to host the public parts of my personal site. What can the Slashdot community recommend as a good, inexpensive VPS provider for personal use? This will mainly be hosting a blog and a couple of Free Software projects (wikis, git repositories, etc.). I would prefer something with KVM so I can manage my own OS install but I am open to other options. Root shell access is essential."

Average Web Page Approaches 1MB 319

MrSeb writes "According to new research from HTTP Archive, which regularly scans the internet's most popular destinations, the average size of a single web page is now 965 kilobytes, up more than 30% from last year's average of 702KB. This rapid growth is fairly normal for the internet — the average web page was 14KB in 1995, 93KB by 2003, and 300KB in 2008 — but by burrowing a little deeper into HTTP Archive's recent data, we can discern some interesting trends. Between 2010 and 2011, the average amount of Flash content downloaded stayed exactly the same — 90KB — but JavaScript experienced massive growth from 113KB to 172KB. The amount of HTML, CSS, and images on websites also showed a significant increase year over year. There is absolutely no doubt that these trends are attributable to the death throes of Flash and emergence of HTML5 and its open web cohorts." If you have a personal home page, how big is it?
