Bash To Require Further Patching, As More Shellshock Holes Found

Waffle Iron Re:Time to retire bash! (323 comments)

Python? You serious? Bye bye one liners with for loops or anything else. I really doubt anyone wants to have pretty code enforced on them for something as simple as iterating through a few numbers one time, ever.

$ python -c 'for x in range(3): print "One"; print "Liner!"'

Could We Abort a Manned Mission To Mars?

Waffle Iron Re:No, who cares? (255 comments)

A single human on Mars could do in a week more than every previous rover on mars put together has accomplished to date.

Sure. And at only 100X the cost of all those missions, it would be such a bargain.

The Great Lightbulb Conspiracy

Waffle Iron Re:I dunno about LEDs, but CFLs don't last (595 comments)

I was looking at LED replacement bulbs at the hardware store the other day ($20 each). I am suspect as to their efficiency.

Get a Kill-A-Watt meter and test the power consumption of LEDs youself. All the ones I've checked have used just about exactly what it says on the package.

They have large heat sinks on the which get very hot. That is wasted energy.

They have heat sinks because the LEDs need to stay very cool to work properly. Incandecent bulbs don't use heat sinks because they need to heat up to thousands of degrees just to get a small fraction of the photons they emit into the visible range. Now which do you think is wasting more energy?

There is no way to pack an efficient transformer into such a small space.

I doubt that any CFL or LED on the market is using a plain 60Hz transformer. They're using switching power supplies, which can be very efficient. That's becuase they crank the frequency up to a range where a small transformer *is* efficient.

Houses need wired seperately with a lower voltage appropriate for powering LED lights.

You'd still need a switching power supply to match the low voltage to the exact needs and wiring pattern of the particular LEDs. That's why most every PC have a separate power supply on the motherboard just inches away from the main power supply to convert 5VDC to whatever the processor needs.

Not to mention the power loss of low-voltage wires. If you put 100W of LED lights (about 6 bulbs) in a room at the end of a 50-foot run at 5V, you'd be pulling 20 amps. If you used 14AWG wire, at 0.25 ohms for the 100 foot round trip, you'd have a 5V voltage drop just from the resistance of the wire. You would also be violating code, which would require you to install a dedicated 12AWG circuit just to power 100W. That's obviously completely unworkable.

In summary, all of your uninformed "gut feel" opinions on these technical issues are unsurprisingly wrong.

IBM Solar Concentrator Can Produce12kW/day, Clean Water, and AC

Waffle Iron Re:Plain solar panels cost less (268 comments)

Look at the frigging picture in the article. This thing is to be built like a radio telescope, probably with a price tag to match.

No, most PV panels are flat and fixed in place.

Waffle Iron Re:Plain solar panels cost less (268 comments)

It says it's parabolic right in the summary.

TFA shows a parabolic dish made of smaller mirrors. Those mirrors may look flat, but there's no way that they get "2000X" solar concentration unless each individual mirror is also precisely curved.

The whole setup looks far more expensive than conventional solar panels of the same area, or even a larger set of solar collectors capable of gathering the same amount of energy.

Seattle Passes Laws To Keep Residents From Wasting Food

Waffle Iron Re:This has nothing to do with wasting food (383 comments)

Actually, as soon as the garbage men show up, it's the governemnt's trash. I don't see why they shouldn't be free to do whatever they want with their property.

If it's the government's trash, why are they threatening ME with a fine if THEIR trash has too much food waste in it?

Because you have an agreement with the government that they will take possession of some types of your undesirable property in exchange for fixed fee. Part of the agreement is that different types of undesirable materials have to be segregated in order to reduce overall costs, direct and external. You did not properly segregate the materials as specified under the agreement, and therefore pay a specified surcharge. Presumably, this surcharge helps the government offset the cost of having to build a new landfill earlier because the current one is filled up with your otherwise compostable food waste.

Nobody is holding a gun to your head and forcing you to segreagate your waste according to the government's specifications. You're always free to load your garbage in your car, find a privately run landfill who will accept it as-is, and bring it there.

Mirrors are a whole lot cheaper than PVs.

Flat mirrors, maybe. Parabolic mirrors on gimbals with sun tracking mechanisms, maybe not so much.

other blatant examples of government micromanagement (like looking through your trash)

If you don't like the government's terms of service, you're always free to hire a private firm to come in an unmarked van and discreetly take away your food waste.

Seattle Passes Laws To Keep Residents From Wasting Food

Waffle Iron Re:Another terrible article courtesy of samzenpus (383 comments)

Get them in season (early winter months), still on the stalk, and cook them properly (refer to the Good Eats episode on Brussels sprouts, for exmaple). There will still be some variations in quality based on the exact batch you have, but the best vegetables I've ever eaten have been when I found particularly good stalks of Brussel sprouts.

Surprising Result of NYC Bike Lanes: Faster Traffic for Cars

Waffle Iron Re:Bikes lanes are nice (213 comments)

Your statement should apply equally to pedestrians and cyclists. However, pedestrians aren't the ones arguing that they'd be safer walking down the middle of the road than on the sidewalk.

Neither cyclists nor pedestrians travel down the middle of the road.

Because most pedestrians that are hit by an automobile are not on the sidewalk, they're in the road.

As I said, only a small fraction of cyclists are hit while traveling down the road not near an intersection.

At an intersection, by definition, YOU'RE IN THE ROAD, whether you had been on a sidewalk or not. Now read that last sentence again, because you seem to be incapable of understanding that simple geometric fact.

The issue is that motorists rarely look for objects moving faster than 0.5mph coming from a sidewalk. Maybe instead of making cyclists stop and dismount at every goddamned driveway as you want, we should address the original source of the risk and institute a nationwide comprehensive 15 mph speed limit.

I never suggested they didn't get killed by cars all the time. I said they manage to handle intersections just fine. That is, with an acceptable surivaval rate.

Where did you come up with that idea? Pedestrians are routinely killed at intersections, coming from sidewalks. Where do you get the idea that that's acceptable?

I don't hear nearly as much whining from pedestrians rights groups as I do from cyclists rights groups, so I assume that pedestrians have greater success in intersections than cyclists do. Of course, it's possible that cyclists are more whiney. Could go either way.

Maybe they're whiny because they hear unsubstantiated crap like this all the time from ill-informed people like you.

Surprising Result of NYC Bike Lanes: Faster Traffic for Cars

Waffle Iron Re:Bikes lanes are nice (213 comments)

Somehow pedestrians manage to handle intersections just fine, all while staying on sidewalks and crosswalks. Perhaps if navigating intersections is too challenging on a bicycle, one might dismount and walk the bike cross?

Pedestrians get killed by cars all the time. Please stop talking out of your ass.

Surprising Result of NYC Bike Lanes: Faster Traffic for Cars

Waffle Iron Re:Bikes lanes are nice (213 comments)

Yet only something like 5% of bike injuries involve being rear-ended by cars on roads.

Almost all other cases would involve intersections of some sort, where being on the sidewalk doesn't help or is counterproductive. You're still vulnerable to the high-speed cars while crossing roads, and you're more likely to collide because they're not looking at where you're coming from.

If we could only arrange for every segment of every bike trip to enjoy a 3% downhill grade, a stiff tail wind, 40 degF dewpoint and partly cloudy skies, then almost nobody would even bother to buy a car.

Waffle Iron Re:Bikes lanes are nice (213 comments)

You are not kept away from cars on a sidewalk.

Since drivers rarely look for traffic on sidewalks as they go in and out of driveways and side streets, you run a high risk of getting run over at every curb cut. At least when you're on the road, drivers usually see you when they bother to glance up from their cellphones.

It seems odd that the pigs are too irradiated to eat but seem to thrive and breed just fine.

2 Galileo Satellites Launched To Wrong Orbit

Waffle Iron Re:Stupid metric system (140 comments)

In fact 'imperial' system is stupid. It is even retarded.
12 inches to 1 foot, 3 feets to 1 yard, 1760 yards to 1 mile, ...
This is just moronic.
Compare to 1km = 1000m = 100000cm

My theory is that the illiterate medieval peasants who invented those systems had an intuitive knowledge that a duodecimal number system would make a lot more sense than decimal, and they ended up creating various half-assed implementations of it for their measurements. (The mile thing is different; it's a Roman decimal measurement of steps).

Unfortunately we did end up using decimal, and reinforced it with Arabic numerals, which makes those intuitions worse than useless in the modern world.

New EU Rules Will Limit Vacuum Cleaners To 1600W

Waffle Iron Re:My two cents (338 comments)

All you have to do is to tell people. People are not stupid.

Then how do you explain the fact that after well over a decade of people being "educated" that Triclosan in hand soap is useless and probably dangerous, almost every soap on the market is still laced with it?

I'll explain it: such education simply doesn't work. The average person can not hold enough factoids in their brains to make the correct decisions on all of the things they need to purchase in modern life. Morever, the manufacturers are constantly bombarding those same people with misinformation and half-truths to promote their products. (This soap is Antibacterial!!!)

Without a ban, tax tweaks, or large mandatory warning box on the package that says "This vacuum an ineficient power hog. Do not buy.", then absolutely nothing will happen. (I'll also point out that the difference between increasing the tax on one thing and rebating it on something else is purely academic. They're both effectively raising the share of overall tax burden on one set of goods and reducing it on the complementery set.)
