FCC Proposes $48,000 Fine To Man Jamming Cellphones On Florida Interstate

jakedata Darwin shot and missed on this one (427 comments)

Imagine he was in an accident and rendered unconscious with his car still powering the jamming device. Assume it was a single car accident, no need to be cruel to others. Anyhow, nobody can call for help and nobody thinks to switch off the ignition in his vehicle which is clearly not running. If it jammed first responders communication equipment too, all the better. He could enjoy a nice long wait for an ambulance.

Ask Slashdot: What Tech Products Were Built To Last?

jakedata HP LaserJet 4M+ (702 comments)

It sits there in standby waiting for print jobs that almost never come, then with a wheeze the top fan blows out the accumulated dust, the lights dim briefly and I get my printout like it was 1999.

Prototype Volvo Flywheel Tech Uses Car's Wasted Brake Energy

No shatter. It's spun carbon fiber. You end up with a big bowl of carbon spaghetti.

Electric Bikes Get More Elegant Every Year (Video)

jakedata Re:pffffft.... (164 comments)

No room for disk brake on the front as the motor is a massively oversized hub. The goal is to put a disk brake on the rear and a heavy-duty cantilever on the front.

Until I can justify the price of the battery pack I want, it doesn't matter anyway.

Electric Bikes Get More Elegant Every Year (Video)

jakedata I built one 10 years ago (164 comments)

http://hardware.slashdot.org/story/04/10/03/2137229/e-bike-e-xperiences/

Based on a steel mountain bike frame, it's decidedly INelegant and heavy, but super-effective on a commute that rarely exceeds 20 MPH by car.

I got a solid 7 years out of a 36V 10AH NiMH battery pack before it croaked. Now it is resting in the basement until I decide to re-power it with some flavor of lithium.

In the original post I asked if the Golden Island machinery motor was any good. Neither the motor nor the controller gave me a day's trouble though the original wire was too thin.

I also asked about lead-acid batteries. They were garbage. Too heavy and the power faded below a useful level long before they were considered discharged. I got a good deal on an NiMH pack and was very pleased with it overall.

I have since lashed up a 48V test pack and really enjoyed the power it gives. The original controller seems to work fine at 48V, the capacitors are all rated 60v.

The best thing I did was add a Watts-UP meter so I can keep an eye on remaining capacity and monitor power flow.

The most alarming thing about the bike is the brakes which are marginally adequate for the combined weight of bike and rider. They need to be upgraded before I hit the road again.

Big Buck Bunny In 4K, 60 Fps and 3D-stereo

jakedata Re:Wow, Pixelicious! (102 comments)

Frankly, I thought I'd never be able to play 4K video on my system.

Windows Media Player is completely unable to handle it and YouTube@4K is jerky at best, even with all the tweaks in Chrome turned on.

I am running a Radeon HD7700, Seiki SE50UY04 and a Core 2 Quad with Windows 7 x64 and the latest Catalyst and VLC.

Once I turned on hardware decoding in VLC it played flawlessly. I can stream YouTube videos to VLC but I can't get them to send 4K yet.

Big Buck Bunny In 4K, 60 Fps and 3D-stereo

jakedata Wow, Pixelicious! (102 comments)

Finally some 4K content for my Seiki. Normally I just use it as a computer display. VLC has experimental support for hardware accelerated decoding which is absolutely necessary to play back 4K video.

It looks great, nice work folks.

Is It Time to Replace Your First HDTV? (Video)

jakedata I wish I could replace it (418 comments)

but it is a 36" Proton CRT with native 720p and 1080i. Lovely picture but it weighs around 250 lbs and wedged so thoroughly into the entertainment center that I might need to cut it out.

Compared to my 1st computer's memory ...

jakedata Re: Tandy 1000TL (587 comments)

It came standard with 512k but could be upgraded to 640k by inserting individual DIP RAM chips into sockets on the motherboard.

Of course the 1000TL had DOS 3.1 and Deskmate in ROM so you could decide to count that as well.

jakedata Does ROM count? (587 comments)

I had Hayden's Stimulating Simulations and a big pile of magazines to copy programs out of. That's pretty much like ROM.

The bicycle I most often ride is ...

jakedata Re:My e-bike made the /. front page in 2004 (356 comments)

You underestimate my next battery pack. It will be in the neighborhood of $800 when you add in the battery management board and quick charger. I have some lead acid on it now for testing the controller at 48 volts but that is impractical for real use.

The bicycle I most often ride is ...

jakedata My e-bike made the /. front page in 2004 (356 comments)

I used it to flatten out the hills 16 miles each way to and from work.

The best thing about it was passing the spandex-clad Harvard bike team while pedaling 20 mph uphill with my flannel shirt flapping in the breeze. Priceless...

The NiMH pack lasted until 2011. The bike is now offline until I can scrounge the money for a LiFePO4 pack.

Ask Slashdot: What Type of Asset Would You Not Virtualize?

jakedata gotta have a night light server (464 comments)

Imagine coming up from a stone cold shutdown. What would be a super thing to have? How about DNS and DHCP? AD too if that's your thing. Some nice little box that can wake up your LAN in 5 minutes so you can start troubleshooting the boot storm as the rest of your VMs try to start up and all get stuck in the doorway like the Three Stooges.

Gates Foundation Makes Progress On Reinvented Toilets

jakedata Re:Must be missing something... (167 comments)

I own several composting toilets. I am looking forward to something far better.

If you want to "flush" to the composting location then you need an ultra-low water head. This is problematic for many reasons. If you don't want a flush then you need to rely on gravity and need a vent fan to keep the bad air out of the house. This is problematic too.

If the compost gets too dry, the process slows, and you end up with fungus that attracts fungus flies. If the compost gets too wet, well ewww.... you have to clean out the system before it overflows.

In winter the compost may not generate enough heat to keep the system from freezing. More ewww...

It is especially difficult to run a system with guests. Imagine spending 10 minutes explaining how to use the toilet. What can go in, what can't, how to flush, what is that stuff down there...

Sleeping iPhones Send Phantom Data

jakedata Disable 3G, place next to amplified speakers (248 comments)

You can catch it in the act.

I just turned off WiFi and 3G, forcing my iPhone onto AT&T's 850 MHz 2G network.

Now any data transmitted triggers a very audible BRAPPPA-BRAP-BUZZ! through the speakers.

Turn up the volume and go to bed.

On EDGE it will take a long time upload all that data. It will be quite obvious if this is really happening.

Also, use cheap speakers, fancy ones might be shielded. I didn't even plug them into the phone.
