To address the affects of global warming, a team of designers "propose building ice-making submarines that would ply polar waters and pop out icebergs to replace melting floes," reports NBC News: "Sea level rise due to melting ice should not only be responded [to] with defensive solutions," the designers of the submersible iceberg factory said in an animated video describing the vessel, which took second place in a recent design competition held by the Association of Siamese Architects. The video shows the proposed submarine dipping slowly beneath the ocean surface to allow seawater to fill its large hexagonal well. When the vessel surfaces, an onboard desalination system removes the salt from the water and a "giant freezing machine" and chilly ambient temperatures freeze the fresh water to create the six-sided bergs.

These float away when the vessel resubmerges and starts the process all over again.

A fleet of the ice-making subs, operating continuously, could create enough of the 25-meter-wide "ice babies" to make a larger ice sheet, according to the designers. Faris Rajak Kotahatuhaha, an architect in Jakarta and the leader of the project, said he sees the design as a complement to ongoing efforts to curb emissions.
"Experts praised the designers' vision but cast doubt on the project's feasibility."

dryriver writes: The BBC reports on a 50ft long and only 120kg heavy blimp-like UAV aircraft that is designed to fly at 70,000 feet, is entirely solar powered, uses variable-buoyancy for propulsion, and can essentially stay airborne in a self-powered way until it experiences mechanical or electrical failure. The Phoenix varies its buoyancy continuously using a helium-filled fuselage that also has an interior air sack that works a bit like a lung. It can inhale air and compress it on demand, making the aircraft temporarily heavier than air, and expel the inhaled air through a nozzle at the back of the aircraft, making the aircraft lighter than air again, creating some extra forward propulsion in the process.

The Phoenix -- which is a simple, cheap-to-build aircraft that its designers describe as "almost a disposable aircraft" -- could one day act as a satellite replacement flying at 70,000 feet. It may also be used for surveillance purposes or to release micro-satellites into earth orbit. The Phoenix has already completed short test-flights of 120m inside the hangar it was built in. This YouTube video shows just how gently the Phoenix rises into the air, hovers in place, and lands again. Unlike drones that need to land, refuel and then take to the skies again, the Phoenix may stay in the air for very long periods of time, landing only for periodic maintenance of its electrical and mechanical components.

The Verge mentioned in their review that the Surface Book 2's power supply can't charge the battery fast enough to prevent it from draining in some cases. Microsoft has since confirmed that "in some intense, prolonged gaming scenarios with Power Mode Slider set to 'best performance' the battery may discharge while connected to the power supply." Engadget reports: To let you choose between performance and battery life, the Surface Book has a range of power settings. If you're doing video editing or other GPU intensive tasks, you can crank it up to "best performance" to activate the NVIDIA GPU and get more speed. Battery drain is normally not an issue with graphics apps because the chip only kicks in when needed. You'll also need the "best performance" setting for GPU-intensive games, as they'll slow down or drop frames otherwise. The problem is that select titles like Destiny 2 use the NVIDIA chip nearly continuously, pulling up to 70 watts of power on top of the 35 watt CPU. Unfortunately, the Surface Book comes with a 102-watt charger, and only about 95 watts of that reaches the device, the Verge points out. Microsoft says that the power management system will prevent the battery from draining completely, even during intense gaming, but it would certainly mess up your Destiny 2 session. It also notes that the machine is intended for designers, developers and engineers, with the subtext that it's not exactly marketed as a gaming rig.

An anonymous reader writes "Video game designers and astronomers have been working different ends of the same problem: how to chart a galaxy full of stars. Astronomers start with observation, finding new and better ways to look into the sky and record what they can see. Game devs take the limited data we have as a starting point, and assume that everything else in the galaxy obeys roughly the same rules. They generate the rest of the galaxy procedurally from this data. But the information flow isn't simply one-way. As developers like David Braben improve their galaxy-creation models, astronomers can look at the models and see where they match (or not) with further observations, allowing them to improve their own scientific models in the process. "'The conflicts that show up are generally due to simplifications made in the models, for which new observations can provide improved guidelines. There's a continuously evolving and developing understanding of space, in which both models and observations play important roles.' ... Elite's model has expanded Braben's understanding of planet formation and distribution. Braben boasts that his games predicted extra-solar planets ('These were pretty close to those that have been since discovered, demonstrating that there is some validity in our algorithms'), and that the game's use of current planet-formation theories has shown the sheer number of different systems that can exist according to the rules, everything from nebulous gas giants to theoretically habitable worlds.""

Komi asks: "I work for a big semiconductor company, and I'm part of a group that is spear heading the Linux movement here. Right now everyone uses Sun machines to design, but you can get a cheaper Linux x86 machine that is four times faster. So it is my job to prove that Linux works. The problem is that I'm an analog circuit designer stuck in the role of sysadmin. So I need some advice on what goes into a network. It won't be that large right now, but it has to be scalable for up to a couple of hundred machines. If this works, then hopefully we'll convince all designers at my company to make the switch."

The Internet and its distinctive architecture have created a freer culture than we have ever had before -- or even imagined. The next few years will decide whether the Net will be made to conform to existing laws and values, or whether society will recognize it as a new kind of realm. The fighting has started. (Read More).

Universal Access to computing and the Net is edging closer to reality. One company after another is now offering computing equipment and Net access to new employees. enRamp announced last week that it's offering a program to provide complete technology benefits to associates and their families. This is definitely a great moral (and business) idea whose time is coming. (Read More).

If you click the read-more link below you will be treated to an excerpt from our own Jon Katz's new book Geeks. Regular readers know my aversion to paper books, but I've read this one, and it's worth your while. Katz explores Geek culture by following a couple of geek kids from Idaho to Chicago. It's a true story, and Jesse and Eric are Slashdot regulars. We don't feel right writing a review of the book since we'd be sadly biased, so read this chapter, and make up your own minds about it... but I hope you enjoy it. This is a story that I think many of us will understand.

Pundits in media and politics are already going into overdrive hyping 2000 as the year in which the Net will crash into the American political system like a tidal wave.

It's not going to happen. Washington is the last holdout against the wall-busting power of the Net. They'll go kicking and screaming, but not next year.

Since no studio could possible make a movie as simple or original as the "Blair Witch Project" any longer, they're blaming the success of the movie on the Net, calling it the "first Internet movie. Wait a minute... It's a great movie, but is it worth the cover of both "Time" and "Newsweek?" The hype is getting scarier than the movie.

The Internet is a World Without Walls rising up in the midst of a culture that's criss-crossed with them, and whose most powerful institutions -- politics, business, education, media -- depend on walls. The Information Architects of the Web are creating new kinds of wall-less, linked structures never seen in the world. In response, battles over walls and the Internet are breaking out all over the place, from MP3's to domain names. This collision is going to be a head-banger, one of the bruising economic and political tussles of the coming decade, perhaps beyond.
