Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days

fluffy99 Re:Hoax (973 comments)

if it works, they should have no problem just selling off energy?

how much energy should there be released from the transformation process to the end product? what they claim or not?

Only works if the magic ingredients are cheaper than the resulting power. If if this is on the up&up, they dumped $50 of power into it and got $100 heat back out. Can you turn that heat into $50 of electricity? Did it consume more than $50 of ingredients, manhours, and reactor materials?

Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days

fluffy99 Re:He tried patenting it... (973 comments)

The sample was tested before being put in. Ash was pulled from the reaction and tested afterwards. That ash very likely contained stuff from the reactor casing. That they were not allowed to dissect and analyze the casing makes me wonder it it was actually constructed as described - an alumina casing with embedded inconel resistance heat wires. It wouldn't be the first time an experiment was tainted, either accidentally or intentional.

Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days

fluffy99 Re:He tried patenting it... (973 comments)

Have another look at that diagram. It looks fine to me. The SW is the power disconnect. They are measuring the 3-phase power into the control system and measuring what's being fed to the resistors. There are no doubled cables being measured. If the control system was somehow trying to sneak power using high frequency that the power meter couldn't sense, it would surely be noticed on the input side measurement but I didn't see any data that compared controller input power to output power..

I was more troubled by their method of estimating the radiating and conducting heat loss by using a thermal imaging camera and using "literature" to derive the crucial variables needed to use this method. There are much more scientific methods of measuring heat.

The real test will be if someone else can reproduce the results.

Drupal Fixes Highly Critical SQL Injection Flaw

fluffy99 Re:Is Drupal 6.x Affected? (53 comments)

I've seen no mention of whether or not Drupal 6.x is vulnerable; are they?

No, it won't be affected, as the API involved was introduced in Drupal 7.

No, but it's certainly an indicator of the quality of code. Don't be surprised if other vulnerabilities are discovered as everyone shifts their attention and starts scrutinizing the rest of the code. The code diff is below. It's a pretty amateurish mistake, and had someone reviewed or tested the original code, they'd have seen it didn't do what it was supposed to. The comments even give you a big hint what the next vulnerability is going could be.

Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life

fluffy99 Re:No mention on capacity though (395 comments)

In 2012 the US used 360 million gallons per day.
http://www.nacsonline.com/Your...
(360 million gal gas) x (33.4KWh) = about 12,000 GWh = 500 Gigawatts averaged over 24 hours.

Lets assume 25% of the vehicles convert to electric only, and they are 4x as efficient (your 25 mpg versus 100 mpge), thats 31 gigawatts

For comparison, the current US electric power production capacity is around 1100 Gigawatts with current average consumption around 500 Gigawatts. Realistically, you never have more than 80% of capacity online, and that last 10% is expensive gas turbines versus cheap coal.
http://www.eia.gov/electricity...

So after some significant hand waiving, and napkin doodling - I estimate that converting 25% of the cars to electric only will consume somewhere around 10% of the excess generation capacity in the US.

Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life

fluffy99 Re:No mention on capacity though (395 comments)

Going by http://www.nacsonline.com/Your..., an average gas station pumps 3000 gallons of gas. Or 4400 in CA http://energyalmanac.ca.gov/ga...

3000 Gallons of gas = about 110 MW*H. Averaged over 24 hours = 4.6 Megawatts.
4400 Gallons of gas = about 161 MW*H. Averaged over 24 hours = 6.7 Megawatts.

Buffering would have to be pretty big, considering surges of customers.

85 KW*hr in 5 minutes is about a megawatt of power. Even at 10,000 volts, you're talking 100 amps.

Ask Slashdot: Why Can't Google Block Spam In Gmail?

fluffy99 Re:Not me... (261 comments)

I don't have a Gmail account, but Google blocks all e-mail from my server to its accounts...

Than your email server is not configured correctly.

Agreed. Often the reverse DNS lookup isn't setup correctly, or you've sent too many emails that were flagged as spam.

Ask Slashdot: Why Can't Google Block Spam In Gmail?

fluffy99 Re:WTF? (261 comments)

Almost all the mails I find in Google's spam filters are false positives, including Fidelity mailings and many legitimate mailings such as e-newsletters. My gmail accounts get virtually no "real" spam, but Google seems to program its filters to catch something. Mostly it's press releases, some of which do look spammy, but as a journalist I need to receive some of them. But it could be any mailing that meets Google's spam criteria, including a series of rapid-fire emails back and forth or routine administrivia like dental appointment reminders. (Interestingly, it has never flagged LinkedIn notices as spam.)

If you're missing something important, check your Gmail spam folder. You may be surprised.

Or disable the filtering.....

Complain About Comcast, Get Fired From Your Job

fluffy99 Caller ID Anyone? (742 comments)

He might not have had to name his company, if he called from his office. Caller ID would have revealed that. His employer could fire him for conducting personal affairs using company resources, which might also include using company privileged info to find out Comcasts Controllers office phone number.

Complain About Comcast, Get Fired From Your Job

fluffy99 Re:And what's the problem ? (742 comments)

It was more than name dropping. There was a suggestion that he worked at company that could initiate an investigation by the Public Company Accounting Oversight Board (PCAOB), which could be interpreted as a threat. More than likely Comcast reached out to his employer to figure out if the threat was serious, and his employer got pissed.

If I mentioned I worked for the Police and that i could arrest them for theft, when I called to complain about a billing problem, would you have a problem with that?

Smart Battery Tells You When It's About To Explode

fluffy99 Re:what happens when a cell phone battery explodes (97 comments)

User was installing a new battery that failed due to shorting when installed.

Another story of it happening and photo of the aftermath
http://miami.cbslocal.com/2014...

Different incident. User dropped the phone and the physical damage caused the battery short.

The typical failure mode from dendrite formation is the battery slowly drains itself from the high resistance connection between the cathode and anode that forms, and not a thermal runaway but it can happen. This is a common failure mode for NiCad batteries, but Lithium batteries are much more heat sensitive and the electrolyte when heated too much can release oxygen to fuel a runaway reaction. Battery failures in portable electronics are typically due to physical damage or poor quality chinese made batteries, especially when they omit the protection circuits.

Possible Reason Behind Version Hop to Windows 10: Compatibility

fluffy99 Re:How badly coded are Windows applications? (349 comments)

I am an electronics technician and have been one since 1964 and I've never heard of that nomenclature.

It's 2.2 K, and 1.5 M.

Period.

But I'm America-centric which often bites me in the butt. :)

I'm very surprised you haven't seen this, or the similar notation on ceramic caps. It's used simply because a decimal is easy to miss when printing on small components.

Antarctic Ice Loss Big Enough To Cause Measurable Shift In Earth's Gravity

fluffy99 Re:PLEASE READ (232 comments)

A portion of that ice is sitting above sea level, so as it melts and the liquid water flows away there's less total water in the area.

Which Cars Get the Most Traffic Tickets?

fluffy99 Re:#6, VW Rabbit? Really? (261 comments)

Well the most popular color for the Prius C. is that glaring orange color.

To me, the data doesn't show what cars attract tickets or prove any bias. To do that you'd have to assume all drivers commit traffic violations at the same rate independent of car model. It probably better represents what cars people who like to speed prefer to drive, and possibly so bias on what car models are more popular in areas that have higher enforcement.

Except Google has servers in Canada. So the argument would be more like a German store, but they ship from a warehouse in Canada.
