Multiple Manufacturers Push Hydrogen Fuel Cell Cars, But Can They Catch Tesla?

0100010001010011 Re:Where do you fill up? (275 comments)

Both gasses are "natural gas"

They are natural gasses but they are not Natural Gas: Natural gas is a hydrocarbon gas mixture consisting primarily of methane, but commonly includes varying amounts of other higher alkanes and even a lesser percentage of carbon dioxide, nitrogen, and hydrogen sulfide.

You wouldn't be able to run the same car on that.

Why not? I make my living on large engines that run natural gas just fine. If you can run a car on propane you can run it on natural gas. You just have to account for knock and energy density. At which point Natural Gas runs better than propane. Methane has a Octane rating of 120. Propane has an octane rating of 112. (Most cars run on 87-93 in the US).

Honda has sold a natural gas vehicle in the US since 1998. https://en.wikipedia.org/wiki/...

And the US Department of Energy is trying to get companies to make a cheaper home filling station: http://www.cngnow.com/news/pos...

Multiple Manufacturers Push Hydrogen Fuel Cell Cars, But Can They Catch Tesla?

0100010001010011 Re:next gen batteries (275 comments)

> That should be enough to charge a decent battery in a few minutes.

Gasoline density is 32.4 MJ/L.

Assume a 60L tank (~16 gallons).

Assume you can fill up your vehicle in 10 minutes.

60 L/10 min * 34.4 MJ/L = 3.4 MW

That's nearly 7 times faster than your 500 kW charger. Assume a 475 mile (30 mpg * 60 L) / 765 km (60 L / (7.84 L / 100 km)) range from that gasoline fill up.

That means your "quick and speedy" 10 minute 500 kW fill up can provide all of 70 miles of range.

It's a matter of physics.

0100010001010011 Re:Where do you fill up? (275 comments)

That's why I don't get why they're pushing Hydrogen.

With CNG I can fill up at home. It'd be like installing a high current plug except I'd pipe NG to a compressor and let it fill up my car.

Natural Gas is already flowing through hundreds (thousands?) of pipelines across the US. There are already filling stations. Honda has offered a CNG fleet vehicle for ages.

Get the price of a home compressor down to a Level 2 charger ($1000) and let me by a CNG car.

Aereo Files For Bankruptcy

0100010001010011 Re:innovation thwarted (137 comments)

Split Comcast down the middle. Internet on one side. Cable TV on the other. Ma'Bell style.

Apply what ever laws for DSL to have dry loop DSL to Coax so that you have dry loop COAX.

Then you could have separate companies competing for your coax internet. Comcast wants to charge their prices? Fine. Some local startup (operating over the dry loop coax) could offer unlimited data. Maybe another offers a "Netflix" package since they have a local NetFlix mirror at their offices. They could pay any of the local fiber providers for backhaul to Netflix. Everyone wins (except for Comcast's internet division).

It will also force the Comcast Cable TV to innovate because they can't trap cord cutters by raising internet rates.

Coding Bootcamps Presented As "College Alternative"

0100010001010011 Re:Given how most spend their time in college... (226 comments)

> Oh, god, don't make me support those people's code.

Why? Do we make engineers 'support' the welds from a welder. Do we make engineers 'support' the plumbing from a plumber?

There is a huge gap between hiring a full engineer and hiring a technician. There should be an analogous range for software. Right now that gap is being filled by cheap Indian and Chinese programmers.

Coding Bootcamps Presented As "College Alternative"

0100010001010011 Re:Given how most spend their time in college... (226 comments)

Code Monkey == Wrench Monkey.

Which is what the US sorely needs. We stopped telling people to go into trades because EVERYONE HAS TO GO TO COLLEGE. I was told in high school I couldn't take welding because I was "going to college." Guess what jobs are in short supply these days? Welding, plumbing, etc.

Sometimes you just need a trade to do a job. Do I need someone that understands coupled classes or a hashtable to build me a website or implement an idea in C? No. If you put 5-10 good coders under a good software engineer I'd trust the output more than trying to hire 3-4 software engineers.

Companies don't hire all engineers, they hire techs as well. We don't need to hire all CS or SE majors but there is a place for them just like there is a place for someone that took a 19-week course on programming.

Joey Hess Resigns From Debian

0100010001010011 Re:Unfortunate, but not surprising (450 comments)

Is there a good *BSD that has figured out binary package management yet?

Not that I don't love being able to compile everything from scratch but I've stuck with debian for so long because apt-get "just works".

I think in 8 years of use I've had a handful of issues with it (or aptitude/dpkg) where as I've had many more with Windows dependencies.

Website Peeps Into 73,000 Unsecured Security Cameras Via Default Passwords

It's closer to a big window with blinds. If you don't close the blinds you can't complain about people being able to stand on the sidewalk and see.

Just because the window is a fancy box you plug into the internet it isn't my fault you didn't read how to close the blinds. No one is physically entering my house. I can still call you from my cell phone while standing our street.

Close your damn blinds.

Some Virgin Galactic Customers Demand Money Back

0100010001010011 Re:If the cause of the crash... (165 comments)

What about stuff that can't be controlled by the human? Some modern aircraft only fly because they have a computer doing most of the hard math for keeping the craft stable. The human's input is more or less a 'guide' to follow but a lot of the actuators are in the end controlled by some closed loop controller.

Why CurrentC Will Beat Out Apple Pay

0100010001010011 Re: Not a chance (631 comments)

Those debit 'protections' are when you run it as a debit card with PIN. Almost all debit cards can also be run as credit cards. When they are run as 'signature' credit cards credit card protections apply.

Never use your PIN anywhere but the ATM. Most especially not on any ole card reader you're handed in a restaurant. Most places assume debit and if you hit 'cancel' or 'change payment type' you can always get it to run as a credit card.

OpenBSD Drops Support For Loadable Kernel Modules

0100010001010011 Re:SYSTEM-D SUCKS! (162 comments)

To expand. If it's a script it has a script handler. If it has a script handler it can be rewritten.

There's no reason they couldn't add a few features from newer scripting languages to enable forking of functions or "own fun". If the kernel (the one running said script with said script handler) supports multiple cores/threads it could easily be the more modularized, etc.

All still from one script.

FTDI Removes Driver From Windows Update That Bricked Cloned Chips

I want to know why no one has made an ELM327 replacement.

With CAN, USB, Bluetooth all becoming ubiquitous I think it's time to update the old ODB chip.

Because "No Va" and "Nova" are different like "Notable" and "No Table".

If something was advertised as being 'notable' I wouldn't think that it had no table.
