at some point, I'll have to try a linux gps map and see if its as good as the commercial ones. would be nice to have a fully open source gps system in my car
There is GpsDrive and navit for navigation engines and UIs. I have played around with navit some on a raspberry pi and you can load maps from Open Street Map into it. I would suggest checking OSM for some locations you are familiar with to get a better feel for the accuracy of open source maps. In my experience it depends on the the users in a given are, if they are like myself they will map out almost everything they can, if there aren't many users or ones who aren't obsessive things might not be as up to date.
The question becomes at what point is it financially better to replace the vehicle. A junk yard will give you something like $250 for a vehicle that they show up and haul off, even more if you can still manage to get it into their lot, I have never managed this but came close once. Now at the age of vehicles we are talking about they are what is considered fully depreciated and typically would be worth $1500-$2000 running as a used car to a buyer. I had a vehicle that was fully depreciated for several years until it ceased to work so for that whole time it cost me very little to continue to own it, no major repairs, no additional depreciation, no random stupid shit going wrong, no car payment, cheap to insure. My philosophy has always been to drive them until they suffer the catastrophic failure that isn't worth fixing and get them hauled off and get my $250-$350 from the junk yard.
Modern engines should last that long with regular maintenance, it is all the other crap that fails first. My previous car had 260,000 miles on it and the engine ran great, the automatic transmission went out on it, I have a jeep with 378,000 miles on it and it runs great but is is rusty piece of junk. The most major thing I had to do to that engine was when I replaced the valley pan gasket, intake manifold gaskets and valve cover gaskets since they all leaked a bit and all that only took a day to do and that is taking it easy on a weekend. I also had one of the coil packs fail but that only took about 30 minutes to change most of which was getting to the auto parts store.
While this is true alcohols will push it very far out of either of those bounds. Using a lower octane fuel your car may be dumping an additional 10-15% more fuel in. Now using an alcohol fuel it could be dumping in close to 2 (ethanol) to almost 3 (methanol) times the fuel which would probably put your injectors out of their duty cycle range at the pressure you are running them at. So your options are to either put in bigger injectors, or put in a higher pressure fuel pump, and you should probably put in a higher volume fuel pump any way since you will be moving a substantially larger volume of fuel all the time.
It is more than a little modification. If you are looking to go for miles per gallon ethanol and especially methanol suck compared to gasoline and diesel. They are however excellent fuels for race or performance applications as you can release more energy for a given air charge than you can with gasoline or diesel. Those alcohols also have a higher octane rating and a higher latent heat so you can run higher compressions or higher boost. As far as modifications to properly utilize them you need to adjust the fuel air mixture (bigger injectors or jets if carbureted), adjust the timing, make the fuel system alcohol safe (E100 or M100 are completely different monsters than the E10 blend sold everywhere), this includes the tank, lines filters, pumps, injectors or carburetor, and valves(there is some debate on this). Alcohol vehicles are also harder to start when cold, and I don't even mean cold like it is now when they probably wouldn't start unless you installed a glow plug like system as well. While these things are doable (doing it on my project car that I am doing a full restoration on) they aren't exactly simple on an existing vehicle. Granted you could just adjust the timing and fuel air mixture and call it good but you will have to replace the rest of the stuff when it does fail. The flex fuel vehicles wouldn't need the replacement of parts but they are a compromise since they can run on E0 up to E85 and don't seem to do any of it well.
Well there isn't much gain to be had for electric motors. Cheap crappy ones can be had that get 85%, good ones get around 90%, and I think I read a while back that someone had one that was something like 98% efficient. The biggest problem with electric vehicles is the amount of power needed to drive a vehicle. Gasoline has something like 33KWh of energy in each gallon about 10KWh is actually used to make the car move, the other ~2/3 of that energy is lost as waste heat (friction and combustion).
If we compare a couple of vehicles lets say my 02 BMW 325i and a 2013 Nissan Leaf. My car has a 16 gallon tank which provides me with about 160KWh of usable energy to make the car move and if run from full to empty on the interstate would probably get me something like 500 to 550 miles from where I started. Now looking at a Nissan Leaf with its 24KWh battery and estimated range of 84 miles (EPA estimate which is in the middle of the range). For the leaf to go 500 miles it would need a battery about 6 times the size with a capacity of 144KWh. Also of note the leaf has better aerodynamics so it gets a benefit my car doesn't. So it looks like for a reasonable sized vehicle you do need about 150KWh of energy to go 500 miles. So if you want an electric car with better range you would only see at best a 15% increase in range from better electric motors, but still would need an additional 5x increase in battery capacity to match the range of my car.
Note I actually like electric vehicles and this was not to diminish their usefulness. The next car that gets purchased will probably be an electric for my wife since she has the ideal driving profile for someone who should be using an electric car. Also both cars could be substantially lighter which would extend the range of both of them.
How many times do you think those Mormon kids get doors slammed in their faces in just one day?
I am never mean to them, and don't slam doors in their face. If it is a nice day I am more than happy to sit outside with them on the front stoop and have a discussion about their religion. A number of them have left questioning their own religion which is probably for the better since they hopefully have learned enough to think critically about things.
I had thought that the Catholic church was accepting of science, with the earth being ~4 billion years old and evolution, for a while now. The biggest difference with the Pope Francis over his predecessors seems to be his views on economic issue, which hopefully will spark a wider debate on the issue.
the freaking pope walks up and slaps him with a live trout while declaring him to be an ignorant boob.
I'd pay to see that, but the pope as well as Catholicism has been out of favor with creationists for a while since they are willing to accept science, so I don't think that this would do much.
That still happens but it isn't right after the show aired. The trick is to have friends who aren't dicks and reveal the ending but can offer good recommendations. As an added bonus TV isn't a driving factor in what any of us do. This weekend is going to be prime TV watching for my family since it is going to be so damn cold out and there aren't that many projects that need doing.
If your bottles of hot sauce can't be used as a weapon then it really isn't hot sauce. Considering the stuff I have walked through with it is really a crap shoot, my old SLR camera with the metal body 20 questions, wipe for explosives, and off to get patted down. A handful of shotgun shells forgotten in a coat pocket sent through the x-ray machine walk right through unaware.
To my American friends: I am honestly terrified by the thought of crossing your border, and I am not alone.
Don't feel alone I am terrified at the thought of crossing my country's border as well, even as a citizen. Every country it s so much simpler, two simple questions of work or recreation and how long I am staying, then get the simple stamp on the passport and walk on through. The last time I came back to the US was from Israel and had gone through their proper security. Didn't even have to take off my steel toe boots when going through security there. I get here and have my stuff rummaged through, get searched, questioned why I was in Israel, and go for additional screening.
This is probably the most likely explanation, the old don't ascribe to malice what can be explained by incompetence. Just like there are large swaths of the American public who are applauding this ruling to help keep us safe from them evil doers. These are people like my mother who believe there is a terrorist under every rock and behind every blade of grass and expose the "if you have nothing to hide", or "protect the children" crap and that we need to stop these statistical anomalies at all cost.
Reminds me of a story my AI prof told about creating an expert system for deciding when cheese was fully ripened.
The cheese company had a person who's job it was to check the cheese and would go and poke the wheels to see if they were ready. The company created a robot to go and do the same job and trained it by having it poke fully ripened and unripened cheese. The problem was that when it was put it use it failed miserably at correctly and consistently telling if the cheese was ripe. The problem was the wrong input, the old cheese tester would poke the cheese not to see how squishy it was but was poking it to let some of the smell out. I don't know how true this story was and it was told to me almost 15 years ago but it seemed reasonable.

Why worry about air resistance, it can have rather interesting effects that would probably help improve DC.
But to do that they first have to rule that it isn't a tax so there is standing to sue.
