    Sure. And as you can see I ran the numbers against a prius too. The point of the exercise was not to compare a brand new SUV to a brand new Prius. Rather it was to compare the cost of changing from an existing gas guzzler SUV to a new car, which addresses the point the OP made about his cost per mile of his car. My point is that his cost per mile is too low. And once you do factor in the entire cost, fuel economy really doesn't enter into the economics at all, for a significant portion of the car's lifetime. In fact on the Prius numbers, the cost per mile doesn't settle on the pure fuel cost until about 300,000 miles (that is not comparing it to any other vehicle).

    My SUV certainly did cost $10,000. As I said I've put 30,000 miles on it since I bought it. And right now if you were in the market for a vehicle you probably could find a used one for that price still, though there is a run on used vehicles, so prices are a bit higher. I could have bought a $5000 car and reduced my costs. But going green and buying a hybrid is not likely to make economic sense for the length of time I'd drive it.

    Hate to reply to my own post, but if I put the cost of continuing to drive my gas guzzler against a Prius at $26,000 and 50 MPG (if I had one I could never get that as my driving is mostly highway), it's about 80,000 miles before the Prius becomes more economical. It's fun and eye opening to crunch these numbers. And of course I'm not taking into account loans or maintenance costs, which could make the break-even point sooner or later. And obviously I'm pitting my used vehicle against a new one, which will always have a much higher initial cost per mile. To me, though, it also says it is rarely economical to buy a brand new vehicle.

    Including the purchase of the car is very important in these calculations. For some reason people die of sticker shock at the pumps but have no problem paying at least that much per month in payments on their car. Having said all this, if we reduce it to numbers I don't think you'll find fuel economy factors into the cost as much as you say or would like it to. For example, spending $45,000 on a fuel efficient jetta vs $10,000 on a SUV gas guzzler. The SUV at 14 MPG will drive for 122,000 miles on the difference in cost alone. And actually it's far more than that as the actual cost of paying for the $45k car is going to be closer to $50 or even $60 depending on the interest rate and the length of the loan.

    Let's play with some numbers. With car purchase cost in mind, at $4 a gallon (picking a number here), I drove my SUV about 30,000 miles since I bought it at say 14 MPG (a lot of highway miles) gives me a cost of about 61 cents a mile (2100 gallons or $8400 in gas). The cost of driving the same distance in the $45k car (40 MPG -- we'll be generous) is about $3000 in gas, which in total is about $1.60 a mile.

    Eventually the car will obviously beat the SUV in terms of cost, but it will be quite a while. I was curious, and since my linear algebra skills are bad I chucked the numbers into LibreOffice and found that with these hypothetical numbers, the 40 MPG car will only become cheaper than the SUV in $/mile at the 200,000 mile mark. Really fascinating.

    I can attest that not all German cars can safely go 100 mph even on the Autobahn! I got my rental car just barely up to 100 mph, and at that speed the steering was so sensitive that a bump to the steering wheel would have probably rolled the car. And there's no way it would have taken a curve at that speed. A short, wide sports car this rental car was definitely not! So despite the Autobahn being designed for speed (parts of it are, parts of it aren't), to routinely drive over 80 mph is probably unsafe for a lot of drivers and cars.

    I was nowhere near Berlin where I've heard drivers are really fast; most cars were doing about 120-130 kph most of the time, which was completely comfortable. Despite the marginally higher average speed over an American freeway, I felt much safer because drivers didn't tailgate, they always passed on the left (it's illegal to pass on the right, and illegal to be driving such that someone has to pass you on the right). Also they strictly obeyed speed limits when they were in place, such as across bridges where the limit drops to 80 kph in a few places. Compared to drivers in America, it was very nice.

    Banning them outright is indeed silly. Incandescents work very well for things like ovens, outdoor porch lights in -40 weather. Also they really are more environmentally friendly in places like a closet that you only turn the light on a few times a day for maybe a minute or two, where a fluorescent bulb would never warm up and have its lifespan significantly shortened by frequent starts.

    Now a room that is lit for an hour or more a day, yeah for sure I ditched all my incandescents a long time ago and haven't regretted it, even in fixtures with glass covers. The thing I like most about compact fluorescents is that I can get a much brighter bulb with less heat and watts. Where I'd have a 60 watt bulb in a lamp before (hate indirect lighting!), I can no put a 75 or 80 virtual watt CF. Little 25 apparent watt fluorescent bulbs are excellent in a reading lamp. This said, I'm not convinced they are actually cheaper and I can't say they've saved me money. They don't seem to significantly outlast incandescents, and while they do use less electricity, the savings are not that much compared to TVs, Computers, Fridges, Stoves, Furnaces, AC, etc.

    My shop is lit with a row of fluorescent tubes and a bunch of very large (200 watt) incandescent bulbs. Winters are brutal on the fluorescent bulbs. They flicker a lot while the ballast warms up. As well we replace more fluorescent tubes each year in the shop than bulbs (why would cold affect the tubes?). Which is nice because the bulbs are 20 feet overhead. Getting reliable, energy-efficient replacements for these bulbs would be very nice but I haven't seen any yet.

    Something I didn't realize until recently is that in the northern latitudes (Canada, northern US), GPS coverage has occasional small gaps in it. My John Deere dealer was saying that in some areas every few days about 6pm (happens to be that time in those areas) GPS coverage drops below 1 meter accuracy levels, and in those areas GPS guidance on farm machines becomes unusable for about an hour or so. As well sometimes a satellite goes offline for maintenance. As agriculture is becoming very reliant on GPS (hence John Deere lobbying in washington against LTE usage of adjacent frequencies), this is a problem. Because of this John Deere now uses GPS and GLONASS together to get better coverage. When Galileo provides coverage, it will use those signals too. The point is, more GPS systems simply improve reliability for everyone, if the Chinese allowed western use of their signals.

    I can't disagree with your take on the politics. I do take issue with the technology. Gnome certainly has had problems with being over-designed and over-abstracted. And I won't argue with your assertion about stupid UI choices.

    Compiling Gnome, though, is pretty easy using but time consuming using jhbuild. Most users of course aren't affected in the least by the build process. Qt's build process is self-contained, but takes hours still. The end result is really the same for end users. Having every widget toolkit re-implement every wheel is fairly tiresome. Why not use lower-level libraries like libxml that already work well, and most importantly, are C-based.

    As for the language, basing it on C was a wise choice. It's a far more portable language than C++ or Objective C, and *way* easier to bind other languages too. The GObject model works very well in other languages. Programming GTK+ in C++ is a joy (doesn't need moc either). GTK+ in Python is slick too, and actually manages to be fairly pythonic, unlike PyQt, which is really just C++ code in a python syntax.

    Writing new GObject code is a chore, since there's a lot of boilerplate code to implement vtables, etc, but using GObject apis in regular C code is quite easy. I don't think Gobject is a BS OO extension anymore than C++ is. Functionally and under the hood they are fairly equivalent. No language support is a pain, but Vala is nice for providing that. I basically consume GObject code in other languages, and there has never been any issue there.

    The tl;dr version of this post is that when you say that Gnome has made every mistake possible and that C and Gobject are responsible for Gnome being in a sorry state strikes me as being a rather baseless claim.
