Illuminating Window-Less Houses With a Plastic Bottle

RajivSLK Re:Lighting on ships... (240 comments)

You must be the biggest idiot in the world. The pop bottle skylights aren't for you in your single family home in pasadena. They are for people who earn less than $2/day. The free/cheap. The light pipes cost hundreds of dollars.

Illuminating Window-Less Houses With a Plastic Bottle

RajivSLK Re:Lighting on ships... (240 comments)

They have them in Victoria, BC as well. However, overtime the ones here have turned purple. The glass formula used for prisms contained magnesium.

However, I wouldn't say that this is the same thing as a pop bottle skylight at all. Glass blocks cost money and must be installed by a professional. The pop bottle is waste garbage that is free and can be installed easily.

Cold War Plan Tried To Put a Copper Ring Around the Earth

RajivSLK Re:handy (184 comments)

No it's not boneheaded at all. The US would obviously only launch the rockets containing the copper filaments in the case of a communications failure. That is during an attack in which the soviets were able to knocked out American communication the copper filaments would be launched and be used as a backup.

Seems like a smart contingency plan to me.

Bill Gates Is Beginning To Dream the Thorium Dream

RajivSLK Re:Finally! (327 comments)

Good! Take profits from the worst companies and use it for good. Nothing wrong with that- else-wise someone else will just take those profits.

The arm of the foundation charged with investing and growing the fund should simply chase the best investments without any restriction or influence from the charitable arm. It would be stupid not to.

Canada To Stop Producing Pennies In 2013

RajivSLK Re:Excellent; (362 comments)

The reason the penny costs so much to keep in circulation is not solely the cost of minting. If a penny costs $0.02 to mint but is used in 10,000 transaction in it's life time that would be ok.

The problem with the penny is that they don't get spent. The mint needs to keep producing new ones for retailers to give out and people go home and throw them in a coffee can.

Oddly, this is the exact argument in favour of $1, $2, and $5 coins. People don't spend coins as easily, they tend fall between couch cushions or collect in jars. Until those jars are emptied, and the couch cleaned those coins are basically a kind of interest free loan the government.

UK Cookie Consent Banners Draw Complaints

RajivSLK Re:Most users are not geeks (108 comments)

Clearly the law is misdirected. The law, if needed at all, should require web browsers to explain cookies and how to manage them upon install and on their start-up pages.

Perhaps, even require web browsers to make it easier to view cookies by domain or something. A standardized icon that you click which shows you all the locally stored information for a particular site.

Or maybe something akin to the "lock" icon that shows up when a site drops a cookie and clicking on it gives you the option of viewing and deleting (rejecting) the cookie.

Solar Panels For Every Home?

RajivSLK Re:Don't forget housing and condo boards (735 comments)

No it goes to the bond payments to pay for all the infrastructure in their new McMansion subdivision. That's the new way of building stuff. Instead of the developers and/or the city paying for things like streets, sewers, lights, electrics etc (and then recouping the cost from property taxes and sale of the houses) the developer/city issues a bond registered against to the new properties titles (or the HOA which is then registered against the property titles.)

They then sell the houses and the owners must pay $200 or whatever per month for the next 30 - 40 years on top of the cost of their houses. It basically supplements the property tax.

Solar Panels For Every Home?

RajivSLK Re:Extremely expensive (735 comments)

Seems like a good investment.

If you invested that $17,000 at say 11.1% (average stock market returns for the last 80 years) you would make $1,870/year. About same amount your are saving per year.

At the average return of the S&P 500 - 9% your $17,000 would generate only $1,530/year.

I'm not sure what the total life of your panels are and what maintenance costs may arise but even when you take into account the opportunity costs of the money it seems like a solid 10%+ return.

27 Reported Killed In Connecticut Elementary School Shooting

RajivSLK Re:And yet... (2987 comments)

If I was there with a gun things *would* have turned out differently. To be clear, I live in Canada and I don't own gun nor do I want to. However, had I been there with a gun either I would be dead or I would have killed the gun man that's for sure.

If two or three or five armed people were there then one of them would likely have killed this lunatic before the death toll could rise to this level.

Google's Image Search Now Requires Explicit Queries For Explicit Results

RajivSLK Re:Censorship (369 comments)

Those were the lazy mean parents. They yelled at their kids a lot when they were around but then genuinely didn't look after them. The strict parents of kids I knew always knew where their kids were. Always knew who their kids friends were and were diligent about having their kids call home and tell them what was up. They would never be able to get away with getting near alcohol poisoning because their parents would literally show up at the party and take them home. If they did skip out somehow then they wouldn't be grounded for quite a while.

I'm 30 now and looking back the kids that had somewhat strict parents are the ones who are doing well now. The ones who didn't are in the messed up group.

As Fish Stocks Collapse, Overpopulated Lobsters Resort to Cannibalism

RajivSLK Re:First lobster cannibal's thoughts (231 comments)

Interesting fact about lobsters, they haven't always been considered delicious. In colonial times, lobsters were considered "poverty food." They were harvested from tidal pools and served to children, to prisoners, and to indentured servants. In Massachusetts, some of the servants rebelled and demanded that they would not be forced to eat lobster more than three times a week.

In fact I met a old woman who told me that, when she was young, she would hide and eat her school lunch- her family was too poor to afford anything other than lobster and the other kids would tease her.

I just goes to show you how society, culture and advertising controls our behaviour, beliefs and taste buds.

As far as this lobster "overpopulated" lobster nonsense- call me when you can walk along the shore at low tide and just pick them up by the dozens (as was common in years past). That would be the natural equilibrium population before we started commercially harvesting.

This whole "overpopulated" is clearly perpetuated by someone who wants increased quotas.

NY Attorney General Subpoenas Craigslist For Post-Sandy Price Gougers

RajivSLK Re:Cracking Down On Free Enterprise? (458 comments)

Gouging is not 100% efficient- gouger's will inevitably buy and store more than they sell and still make a profit. Furthermore gouging causes people to hoard. If I know that gas will remain a roughly the same price it is now and likely return to normal in a week or so, I am probably just going to fill the tanks in all my cars and maybe get a small jerrycan before the storm. If I think gas will rocket to $20/gallon after the storm I am going to buy a 500 gallon tank rush to the pumps and suck them dry before everybody else does.

Our behavior will create massive shortages, nothing like what we currently see. Creating an incentive to direct supplies to a disaster area is something that government can do far more efficiently than price gouging.

Also, we haven't even talked about those people who can't afford increased prices. Those people would certainly go without in a gouging scenario. In a large disaster I would imagine that would result in civil unrest, increase crime and violence.

NY Attorney General Subpoenas Craigslist For Post-Sandy Price Gougers

RajivSLK Re:Cracking Down On Free Enterprise? (458 comments)

Allowing price gouging post disaster can be very dangerous because it exacerbates any shortages. No only are people in need vying for scare resources but price gougers who buy and hold much more than they individually need in an effort to reap a profit on resale. This causes more gouging and hoarding as people become scared that prices will increase. The ultimate result is that people will go without and possibly die while resources go unused.

$3,000 Tata Nano Car Coming To US

RajivSLK Re:Power steering isn't a safety feature. (658 comments)

Just to be pedantic - in most situations, ABS will NOT decrease your stopping distance, in fact, by definition not locking your tires reduces friction and actually increases stopping distances.

This is blatantly false. The friction between a locked sliding tire and the road is usually less than the friction that can be applied by braking system while the tire is still rolling. From wikipedia: http://en.wikipedia.org/wiki/Anti-lock_braking_system

ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces for many drivers;
Stopping distances were reduced in most of the tests compared with locked wheel braking, particularly on slippery surfaces, in which the improvement could be as much as 30 percent.

The Long-Term Effect of ABS in Passenger Cars and LTVs
From:www-nrd.nhtsa.dot.gov/Pubs/811182.PDF

Median Percent Reduction of Stopping Distance
ABS Enabled Versus ABS Disabled
Road Surface
Dry concrete: 5% reduction
Wet asphalt/concrete: 14% reduction
Wet Jennite 43% reduction
Wet epoxy 10% reduction
Gravel: 28% increase*
