Try wild strawberries: they are intensely sweet and flavourful compared to their farmed counterparts. Their farmed counterparts have been bred for size and shippability, and taste and eat more like a potato than the original fruit. Wild strawberries are the only exception I can think of though.

Wireless Networking

Why Sys-Admins Are Disabling The Lights on WiFi Access Points (networkworld.com) 294

More than a dozen IT professionals said they've disabled the LEDs on wireless access points, according to a Network World article shared by Slashdot reader alphadogg: Some users don't want a beacon shining in their eyes as they try to get to sleep and others worry about the health effects of a blue light glowing all night. Some even resort to unplugging the gear when they're not using it.... "It seems when you are sick and laying in a hospital bed and have trouble sleeping, the single LED shining in your eyes is an issue," [says the wireless network staff specialist for Penn State College of Medicine]. "I get it and understand it..."

Network pros say they have begun asking vendors such as Cisco if they can provide an easier way to dim, rather than turn off the lights on the access points entirely, via wireless controllers. And some would like to see more granular control, such that the power light could be left on to comfort end users that the device is working, but blinking lights could be turned off or dimmed to avoid bothering them.

End users have tried "all sorts of makeshift fixes -- from Post-it notes to bandages to condom wrappers," but one network architect complains that when they disable the LEDs altogether, "I invariably get a ticket (or more) that the access point is offline and wireless is broken because there are no lights on..." On the plus side, when they then re-enable the LED lghts, "magically the wireless performance and coverage is perfect!"

That depends on two things:

The OpenGL stack. AMD hasn't put the same effort NVidia has into making OpenGL fast. At the moment, almost every 3D program on Linux is using OpenGL.

The porting technique. Some of the games are Linux native, while others use an API translation layer, which includes every game coded against DirectX.

Ah, but regenerative braking does help you in hilly terrain. Trucks waste a lot of energy countering gravity in mountainous areas. Regenerative braking also doesn't fade or wear out with repeated use, so is cheaper in the long run. Regenerative braking is totally worth it for long-haul trucking.

The programming laws for terrestrial broadcasters don't apply to online distribution, thus there are no "Canadian content" requirements for Netflix.

Personally I think we should scrap the Canadian content rules, though with the increasing irrelevance of terrestrial broadcast there's less and less point in doing so.

I would argue it's developers abandoning Windows and moving to Mac. None of the dozen developers where I work use Windows. We're all Linux and Mac, about half and half. I suspect that's why Microsoft created their Linux compatibility layer: to stop the exodus of developers.

Of the developers using Linux, it's a mix of people like me who have been using it for seventeen years and people who have only recently picked it up.

It's not a complete replacement though: the sales and marketing side is about half Windows, half Mac, and no Linux.

Comment Re:During Takeoff? (Score 3, Insightful) 275

Below 10,000 ft, airplanes are travelling at less than 250 mph. At takeoff, it's closer to 175 mph for a jet like a 737. At less than a perpendicular angle, the rate of travel across a field of view is less than that. If a person holds their arm out they can point with a lot of precision -- it's a lot easier than tracking an object at the same distance with binoculars. Furthermore, you must consider being at a distance away from the airplane. The greater the distance, the slower the plane is moving and the easier it is to aim at. Pointing straight up is rarely the issue, but if you're a mile away and the plane is on approach at say 2000 ft, that's only a 20 degree angle. Sitting in the cockpit of a 737, a pilot can see the edge of a taxiway -- the vertical field of view out the window is quite good. The lasers involved in these incidents are often much more powerful than a pen laser pointer and are many are strong enough to cause permanent eye damage. Unlike an incandescent bulb, lasers lose very little energy on the way to their targets. It's like those idiots on the highway who blind you with high beams at night, only much worse -- and I've had my night vision temporarily ruined by headlights a couple miles away. Lastly, there are lots of metal bits in a cockpit to reflect the laser, and the windshields are often marked by micro-abrasions from dust and insects, which can cause the whole windshield to glow.

Here is what it looks like from the cockpit. Are pilots bullshitting? Try driving a car down an unlit rural road at night with that in your eyes and report back to us.

A 1 watt laser is enough to flash the ISS. It doesn't take much.
