Biofuels From Corn Can Create More Greenhouse Gases Than Gasoline

David_Hart Switch Grass (158 comments)

Anyone who knows anything about Ethanol knows that the two best sources are sugar cane and switch grass. Switch grass should be the choice for North America as it can grow just about anywhere. Corn, on the other hand, takes up valuable farm land, requires more water, and has higher production costs. Ethanol from corn is a nothing but a scam perpetrated by the corn industry. Believe this study or not, but there are much better options than corn...

Mercedes Pooh-Poohs Tesla, Says It Has "Limited Potential"

David_Hart Re:Myopic viewpoint (359 comments)

Personally, looking at Tesla, how the company is run and the products they make, I predict that within the next 20 years Tesla will sell more cars per year than Mercedes.

Mercedes has cars in multiple price ranges and doesn't have range issues (gas stations everywhere).

Until Telsa can figure out how to get the pricing down and sell cars near the $30,000.00 (or equivalent) price point AND increase the range AND have near ubiquitous fueling stops (supercharge stations) it's highly unlikely....

SSD-HDD Price Gap Won't Go Away Anytime Soon

David_Hart Re:RAID? (256 comments)

Thanks for posting real benchmarks. I can't afford/don't need a Mac Pro but if PCIe SSD become available on other systems, it's nice to know how fast it really operates.

You mean like this one...

Kids Can Swipe a Screen But Can't Use LEGOs

David_Hart Re:not trolling, really. well, maybe a little.. (355 comments)

Q: What's the most useless lego piece ?

I've always found the single square pieces to be the most useless and the easiest to lose. I could build a detailed model as a kid and the parts that always were prone to falling apart used the single square. Lego always included them in kits where a 1x3 or 1x4 would work better. I understand that they did it to provide a greater variety of pieces for building unique designs but I never ended up using them for anything....

How Apple's CarPlay Could Shore Up the Car Stereo Industry

David_Hart Re:Dead-end Market? (194 comments)

I'm confused. Wasn't the last car capable of a having an after-market head unit installed manufactured a solid 10 years ago? I fail to see the point. The number of such cars is on a rapid decline. For collectors if you're going to buy an ancient car, then wouldn't you be buying it for nostalgia's sake and want the old crappy radio that came with it?

Pretty much, unless you buy a car with just the basic radio. I traded in my 2003 Murano for a new car last summer and it was 10 years old. The A/C controls were built into the Bose radio system. It took an aftermarket company 7 years to release a control panel that would let you swap out the stereo system. Once they did, I was able to replace the crappy Bose with a Kenwood Navigation system without losing any functionality.

My new car is a 2014 Jeep Grand Cherokee and I have the Uconnect 8.4 infotainment system. It's a good system, but everything is built-in to the unit. It would be necessary to get an add-on module on top of a new stereo system to retain all of the current functionality. The only company that I know of that is on the cutting edge of developing these modules is iDataLink (http://maestro.idatalink.com/). They don't have a module for my car yet, but they do have modules for GM On Star, Ford Sync, and older Uconnect systems.

Personally, I wouldn't replace any stereo system to get CarPlay. In my opinion, its a dumbed down system because it requires you to use your cell phone for the majority of the functionality. Plus, if you have a family who all drive the car, everyone will need an iPhone. Give me a unit with built-in Garmin GPS any day....

Your StarCraft II Potential Peaked At Age 24

David_Hart Althetes or Coaches (102 comments)

Starcraft may be popular for strategy game players, but give me a FPS any day. I cut my teeth on Doom, Quake, Unreal, etc. In my opinion, if you want to measure reflexes, spacial awareness, and situational awareness, these are the games to study and would be closer to sports situations where muscle memory and learned strategy kicks in. Starcraft would be closer to what coaches have to do (i.e. football, making play decisions, etc.) than the athletes.

In any case, no matter what game I play, I do play differently than I used to. Much of this has to do with the compressed time I have available. For example, in FPS games I'm a bit more circumspect as I move through levels because I just don't have the time to start over from scratch multiple times. I used to re-play a game several times just to beat my last score or find the last 3 hidden treasure areas. This made me a much better online player as I would know each level completely by heart. Now, I'm lucky if I remember where I picked up that last weapon...

Bachelor's Degree: An Unnecessary Path To a Tech Job

David_Hart Re:It's just a badge... (287 comments)

Look at it this way. The HR person will have two stacks of resumes. One for people with a degree and one for people without. Odds are the only time they'll delve into the non-degree pile is if they find no one in main stack to fill the position. This isn't to say you MUST have a degree to get a job. I lack one and have been employed for a long time. But I'm realizing that as my age gets up there, it will be desirable to get one for my next job.

I actually saw a job posting for a network engineer that was giving preference to people with a Master's degree.

Bachelor's Degree: An Unnecessary Path To a Tech Job

David_Hart Re:If only (287 comments)

If only HR managers understood this or knew that computer science has nothing to do with computers. The entire computer industry was built by college dropouts and is ruled by technology that changes faster then a 4 year degree. Hire people that understand technology and can learn new tech on the run. Degrees are meaningless in tech and are becoming more so in all areas.

Degrees are not meaningless in Tech. They may be in some specific low end tech jobs, but that's a different question. The purpose of university is to teach you how to learn, communicate with others, and how to write. Granted, a large number of people in the tech world have enough natural curiosity to learn on their own without being taught. However, they miss the breadth of knowledge that a college graduate is exposed to (assuming that the college graduate was actually there to learn and not just party).

Bachelor's Degree: An Unnecessary Path To a Tech Job

David_Hart Re:H1B - a path to a Tech Job (287 comments)

I don't know the ins and outs of H1B, but don't they usually require a master degree?

No.

If I remember right, a 1 year TN visa for a Canadian required either a 4-year degree, a 2 year degree + 3 years experience, or 5 years of experience. I could be wrong, but I believe that the requirements for a H1B are similar.

Mathematicians Use Mossberg 500 Pump-Action Shotgun To Calculate Pi

David_Hart Re:Only in America... (307 comments)

I hate to break it to you, but the ancient term "America" refers to the whole continent, Canada included.

Nope - that would be "North America."

Hey, if you're going to be a pedant...

Ok, since we're being pedantic: technically, "America" refers to the entire landmass (made up of the continents of North and South America and associated islands). Still includes Canada, though.

I've never heard anyone refer to the American Continents as a singular; it's always been "the Americas."

Aw, geez, did I really get drawn back into this? You sneaky bastards.

I've always interpreted America to refer to the major continental land mass of North and South America and Americas to include all of the islands.

Ask Slashdot: Are You Apocalypse-Useful?

David_Hart Re:Farming (It's about skills, not profession..) (736 comments)

For example, my mother was a housewife but she volunteered for the local ambulance for years and grows her own garden every summer. So, she knows how to handle triage and grow food.

I'm into kayaking, hiking, sailing, and used to go fishing with my Dad all the time. I even know how to make flies for fly fishing. I'm also a good shot with a gun or bow. All of these are skills that could come in handy during an apocalypse. None of these are skills learned as part of my profession, but more as a part of growing up in Canada.

Can Web-Based Protests Be a Force for Change?

David_Hart Re:I don't think so... (76 comments)

Yeah, that Mozilla guy stepped down, but there aren't a lot of real consequences to that (save for him being out an easy paycheck ).

Take a look at Occupy Wall Street. That was a real movement with real impact. It was also systematically (and very effectively) shut down before it accomplished anything :(.

Occupy Wall Street was a protest by a bunch of unorganized 18 to 20 somethings with no leader, agenda, or coherent message. It had no impact whatsoever, other than on the local police overtime budget. Nothing real came out of it simply because there was no real foundation to build on.

If you want to talk about a movement that was systematically destroyed, take a look at the Tea Party. It was originally started by a coalition of conservatives and democrats for the express purposes of promoting of fiscal responsibility within government. It was systematically taken over by the conservative far right and bears no resemblance to what it originally stood for.

Ask Slashdot: How To Start With Linux In the Workplace?

David_Hart Office Printer... (451 comments)

The first time your boss buys a new office printer/scanner/fax machine with a tonne of fancy features (stapling, collating, etc), it will all fall apart. With Windows you just load the drivers and go. With Linux, well, good luck with that.....

There are just some things that are not worth the effort and running LINUX on office desktops is one of them.... Besides, it's much more fun playing with servers...

How Cochlear Implants Are Being Blamed For Killing Deaf Culture

David_Hart Re:Let it die (510 comments)

Or hell, keep using sign language on your kid even after getting the implant.

It's only dying because people are lazy.

Did you listen to yourself before you wrote this?

My thought is that anyone who was deaf and can now hear due to technology would be too busy learning about the wonderful world of sounds that we live in, hearing the voices of friends and family, exploring music, catching up on their education, etc.. None of this falls under the heading of being lazy.

Meet the Diehards Who Refuse To Move On From Windows XP

David_Hart Re:WTF.... (641 comments)

Though I will say one thing - I'm glad Win7's native explorer sucked enough to make me look for a replacement, because while XP's was Good Enough, now that I've gotten used to having a file manager that supports tabs, I couldn't possibly go back.

You don't have to. There is a free utility called Clover that adds tabs to Windows explorer....

Meet the Diehards Who Refuse To Move On From Windows XP

David_Hart WTF.... (641 comments)

I don't understand the nostalgia concerning Windows XP. It was always a mediocre version of Windows in comparison to NT and 2K. It's main claim to fame was that it was a major leap from 3.11 and wasn't as bad as Windows ME.

Win 7 is a huge improvement, once you disable the user access control (UAC). I agree that Win 8 is a mess with the touch UI. Once you get past it with Start8 or some other utility, it too is a huge improvement over XP. I also understand the frustration with settings, etc., being move around in the menus, but you get used to it after while.

The only thing that I re-enable in newer versions of Windows, that was enabled by default in XP, is the quick launch tool bar. Personally, I have been very happy to leave XP in the dust.

Why Are We Made of Matter?

David_Hart Re:civilizations' bottleneck (393 comments)

And that is why we do not hear any intelligent radio transmissions from other star systems.

But does it explain why there's apparently no intelligent postings on Slashdot?

There were originally equal amounts of facts and anti-facts. Computer Scientists are still trying to explain why anti-facts now make up 99.999% of the postings.

it's simple... facts are boring... anti-facts, better known under the scientific term "made up stuff", are much more fun....

So gamers will be popular either because they are known to be good or simply because they choose the right name and get publicity...

So this is like the difference between Morgan Freeman and Kim Kardashian.

Study: Exposure To Morning Sunlight Helps Managing Weight

David_Hart Sun, whole milk, dark chocolate... (137 comments)

First they tell us that dark chocolate is good for us because of the antioxidants and that it reduces the amount of fat that your body adsorbs from other foods.
http://www.scientificamerican....
http://www.medicalnewstoday.co...

Then they tell us that whole milk, cheese, etc. keeps us leaner
http://www.npr.org/blogs/thesa...

Now bathing in sunlight (don't forget the sunscreen) will help us manage our weight.

So, I guess this means that eating dark chocolate, chasing it down with whole milk, while sitting in the sun and reading (good thing I own a Kindle) will help me get rid of those unwanted pounds... Ahhh... This IS the life.... (grin)
