Interstellar Hydrogen Prevents Light-Speed Travel? 546

garg0yle writes "As if relativity wasn't enough to prevent us traveling at light speed, Professor William Edelstein of the Johns Hopkins University School of Medicine is now claiming that the interstellar hydrogen, compressed in front of the ship, would bring the journey to a shocking end. 'As the spaceship reached 99.999998 per cent of the speed of light, "hydrogen atoms would seem to reach a staggering 7 teraelectron volts," which for the crew "would be like standing in front of the Large Hadron Collider beam."'"

FCC Proposes 100Mbps Minimum Home Broadband Speed 461

oxide7 writes "The US Federal Communications Commission unveiled a plan on Tuesday that would require Internet providers to offer minimum home connection speeds by 2020, a proposal that some telecommunications companies panned as unrealistic. The FCC wants service providers to offer home Internet data transmission speeds of 100 megabits per second to 100 million homes by a decade from now, Commission Chairman Julius Genachowski said."

This article suggests that advertisements should be *more* intrusive, but his examples directly contradict the point. What bothers many people most about pop-up ads and their ilk is not that it requires them to view the content, it's the techniques used such as auto-reopening when you click to close, or opening tens or hundreds of windows. As the author correctly states, many people don't mind watching the pre-commercial on sites like cnn or hulu. The point isn't that those are *really* intrusive but that an advertisement done well in a clearly opt-in way is tolerated. As with the proxy sites he's a proponent of, the key to advertisement is NOT intrusion, it's doing the ad well and making it a clearly opt-in system that makes it good. When I go to hulu or cnn or whatever I have a clear choice - use the site and tolerate ads (assuming the nice model of not using ad-blockers to bypass them), or simply choose not to use the site. With the kind of intrusive pop-ups that the author talks about and suggests creating, it removes the opt-in aspect. Where there isn't opt-in, users WILL get mad at the advertisers and negatively impact them overall... so if they really want better, higher paying ads, the answer is to create good ads, pay for them in targeted spots that actually cover the market, and make sure that the users have essentially agreed to see the ad in exchange for the service. None of that sounds like it *needs* to be intrusive.

Half of Google News Users Browse But Don't Click 237

An anonymous reader writes with this excerpt from the International Business Times: "Nearly half of the users of Google News skim the headlines at the news aggregator site without clicking through to the publisher, according to new research. ... Outsell analyst Ken Doctor said in a statement that 'among the aggregators, Google's effect on the newspaper industry is particularly striking.' 'Though Google is driving some traffic to newspapers, it's also taking a significant share away," Doctor said. 'A full 44 percent of visitors to Google News scan headlines without accessing newspapers' individual sites.' ... With a number of US newspaper owners considering charging online, Outlook found that only 10 percent of those surveyed would be willing to pay for a print newspaper subscription to gain online access."

How Do You Volunteer Professional Services? 366

keefus_a writes "My wife and I usually take a week long vacation in the Spring and I tossed out the idea of volunteering abroad. Neither of us has a problem with doing manual labor, or whatever task is needed. However, I thought it might be of some value, and substantially more rewarding than our daily grind, if we could volunteer our professional services (I'm a network guy and my wife has a master's degree in counseling). The problem is that I haven't found any resources for doing so on a short-term basis. So I ask Slashdot. Has anyone ever done short-term volunteer work in your professional field? What organization did you contact? Or are we better off donating money to a particular cause and just working on a tan?"

Disney Releases 3D Texture Mapper Source Code 83

dsavi writes "Ptex, Walt Disney Animation Studio's cutting-edge 3D texture mapping library which was first used on nearly every surface in the 2008 animated feature Bolt, was released under the BSD license on Friday. Quoting the announcement on monophyl.com: 'We expect to follow Ptex with other open source projects that we hope the community will find beneficial. We will soon be launching a new Walt Disney Animation Studios Technology page under disneyanimation.com. It will include links to our open source projects as will as a library of recent publications.' This looks good for open source 3D graphics."

Google Hacked, May Pull Out of China 687

D H NG writes "Following a sophisticated attack on Google infrastructure originating from China late last year, Google has decided to take 'a new approach' to China. In their investigation, Google found that more than 20 large companies had been infiltrated and dozens of Chinese human rights activists' Gmail accounts had been compromised. Google has decided to 'review the feasibility of [its] business operations in China,' no longer censoring results in Google.cn, and if necessary, to 'shut down Google.cn, and potentially [Google's] offices in China.'"

Comcast Launches Broadband Meter 199

nlawalker writes "Beginning on Tuesday, January 12, Comcast high-speed internet users in Washington state will have access to an online tool that displays their bandwidth usage for the most recent three calendar (not billing) months of usage, including the current month. Washington is the second market to receive access to the tool, following its introduction in Portland. 'For the fraction of less than 1 percent of our customers who are concerned about exceeding our excessive use threshold, we believe this meter will help them monitor and calibrate their usage,' said spokesman Steve Kipp. Perhaps those who aren't using 250GB a month should take it as a challenge."

New "Wet Computer" To Mimic Neurons In the Brain 132

A new type of "wet computer" that mimics the actions of neurons in the brain is slated to be built thanks to a €1.8M EU emerging technologies program. The goal of the project is to explore new computing environments rather than to build a computer that surpasses current performance of conventional computers. "The group's approach hinges on two critical ideas. First, individual 'cells' are surrounded by a wall made up of so-called lipids that spontaneously encapsulate the liquid innards of the cell. Recent work has shown that when two such lipid layers encounter each other as the cells come into contact, a protein can form a passage between them, allowing chemical signaling molecules to pass. Second, the cells' interiors will play host to what is known as a Belousov-Zhabotinsky or B-Z chemical reaction. Simply put, reactions of this type can be initiated by changing the concentration of the element bromine by a certain threshold amount."

As other people have pointed out, the important thing is that neither Verilog or VHDL are sequential programming languages... They are hardware description languages, or could be thought of as parallel programming languages or simulation languages. In any case, students will make the biggest mistakes by: 1. Thinking that it's just like C/C++/Java/whatever, and 2.Using features of either language (which are both quite powerful), but that are unsynthesizeable.

Thus, an important part of any course on HDL should have a heavy focus on synthesizeable code, with many iterations of seeing not just the "right" way to do things, but why that is the right way and the alternatives wouldn't produce the same (presumably good) hardware as the alternative ways that look or seem similar.

There are many other languages to consider as well that may or may not end up being used widely in industry.. a sampling is...
SystemC
HandelC
BluSpec

Plus, there are many C-to-Verilog, C-to-VHDL or C-to-HW compilers out there that try to jump from sequential code with pragmas etc. to the HW....

In general, I would suggest thinking of this not as a language course, but as a hardware design course where the tools used happen to include a new language (for the students). It would be easy to concentrate on language syntax and end up with students that know syntax, but not how to make good HW descriptions....
