  1. That's interesting, but it's still not much of a reason to go there. You don't need rocket fuel on Mars, except for the return trip.

    The Moon, Ceres, Titan, Callisto, all are easier to land and take-off from than Mars, and since you can land and take-off with much less fuel there's a lot more useful payload capacity to work with

    They're also even farther away than Mars is (except the Moon obviously). This is a big problem with any human mission: who wants to sit in a little tin can for 2 years? We've already seen that zero-g is really really bad for human health in the long term. You can get around that by building a ship with artificial gravity (through rotation), but that requires building a big-ass ship; we can't even do that yet, we can barely make a little space station in LEO out of modules. Don't forget the problem of radiation shielding: having humans out beyond the Van Allen belts for that long is going to expose them to a lot of hard radiation.

    We really should be sending a lot more humans to the Moon to try to build up infrastructure there before we even think about sending humans to places like Callisto. If we can mine resources and building materials on the Moon or from asteroids, and get good at building ships in zero-g shipyards, then we'll be positioned to send humans for much longer-duration missions. Remember the Discovery in 2001? That's the kind of ship you need for those missions, and you can't build that kind of ship on Earth.

    There's a problem with this comparison. When explorers traveled to the New World, it wasn't that hard to live there (temperate climate, plenty of animals to hunt for food). And the economic reasons were pretty obvious: there were bountiful natural resources to be had, including gold, silver, all kinds of new plants (chocolate became a huge thing in Europe after it was brought back from Central America), etc. Gold of course was one of the biggest drivers, and they did indeed bring a lot of gold back; some of it still sits on the seafloor because their ships sunk. Later, colonization became a big draw, and for good reason: Europe was crowded, and there was plenty of open space in the New World (though you might have to shoot some Natives...). And as I said before, there was a temperate climate (except maybe the northeast), with lots of vegetation, and lots of areas excellent for farming (including the entire southeast), so it was a pretty good place to live.

    What exactly is the economic case for traveling to Mars? There really isn't one that I've heard of. All the worlds in our solar system are uninhabitable by humans without extreme life-support measures (sealed habitats of some kind); they're not temperate, they usually don't have atmospheres, or if they do they're useless (Mars) or toxic (Venus), they certainly don't have any native life (maybe we'll find some microbes one day, but it's doubtful), they're too far from or too close to the Sun (Mars is cold; anything past Mars is frigid; Venus and Mercury are hellishly hot), so that leaves only one possible use that I can think of: mineral mining. But considering the distance and expense, is that really worth it?

    If you want valuable minerals, it's far more likely that you'll have an easier time, and far more profit, by mining near-Earth asteroids (and later, farther away ones using robotics), and maybe the Moon. There's tons of asteroids whizzing by the Earth constantly, and by most accounts they have far purer ores than normally found on a planetary body. Sending a robotic mission to prospect and capture an asteroid can be done in far less time than sending a ship to Mars.

    Now if your goal is colonization, first there's no profit in that at all. Also, all the things I mentioned above still apply there: these places are uninhabitable, unless you want to live underground or something. If you really want to spend money on having humans establish a permanent presence elsewhere, the Moon is a much more logical choice: it's very close by (astronomically speaking; it's only 3 days away instead of months or years). Shipping supplies back and forth, or evacuating someone for a medical emergency, would be far simpler and faster. However, there's the problem with the low (1/6 g) gravity which has unknown long-term health effects on humans, but Mars isn't much better there (1/3 g).

    If off-world manufacturing (low-g or zero-g) turns out to be advantageous, the Moon is a better place for that: it's nearby, and its gravity is lower than Mars'. If you need zero-g manufacturing, there's Lagrangian points here in the Earth-Moon system; no need to travel far for that.

    Honestly, until we find some kind of valuable mineral on Mars that we can't get in quantity here on Earth (without significant environmental problems), or on the Moon or from asteroids, the only good reason I can see for a serious human presence on Mars is tourism. But that's a heck of a long way to travel for a vacation; you'll need at least 18-24 months just for the travel time each way.

    I'm all for more offworld exploration, but all this "Let's go straight to Mars!!" talk is really annoying me, because it's completely impractical and puts the cart before the horse. We haven't done much more than just whack some golf balls on the Moon; we're not ready for sending humans that far, especially when there's no really compelling reason to do so, and there's important work to be done closer to home to improve our offworld abilities (namely: exploring the Moon more, establishing bases there, mining asteroids). I still haven't seen any good reasons for this line of thought. It wasn't even very long ago that we discovered water ice on the Moon.

    The Martian atmosphere has 1/200 the pressure of Earth's: in other words, it's barely even there, and really not enough to be useful for much.

    Mars is an interesting place geologically, but it's also a 6-18 month journey from Earth IIRC, which is far, far beyond anything we've ever attempted with manned missions. It's not a trip you can just go on, drive around in some rovers, take photos, and come back home; you need to establish a permanent settlement there of some kind. We've never done that anywhere offworld. The logical course of action is to build a base on the Moon first, so we can get some experience with building settlements on other worlds. The Moon is only 3 days away, and we've been there before with 50-year-old technology, so it's entirely feasible to do a lot more there now. There's still plenty of scientific work to do there, including looking for useful mineral deposits and other natural resources, to see if an economic case can be made for a more permanent human presence there.

    Jumping straight to Mars (or worse, Titan) is putting the cart before the horse.

    I don't have a good explanation, just my own extremely biased view.

    First, people are sheep, and RHAT is the 800lb gorilla of FOSS, especially in the US, so a lot of people just seem to go with them. RHAT is a US company, so they seem to be more popular in that country, along with their distro Fedora. Fedora features Gnome3, so people just use that.

    Also, from what I've read, when you suggest that people switch to KDE, they have two main excuses here: 1) KDE4.0 was a disaster, so they'll never go back, or 2) KDE has too many choices, and they want something they don't have to configure. Gnome3 doesn't have any configuration, so this mindset works well with people like that. (Yes, you'd think those people would be Apple fans, but apparently that mentality is very prevalent in the FOSS world these days too.) If there's something they want to change, they just download a tweak, even though these break every time Gnome gets updated, but they don't seem to mind that. Also, there's 3) they think KDE is ugly for some reason.

    No, none of it really makes any sense to me either. I wish I could give you a better explanation, but I suspect there's a lot of psychology involved.

    Finally, the thing about C++ being significantly slower than C isn't really true these days any more. C still has a place for low-level coding where you need more determinism, but you can do this with C++ too by disabling some features (namely exceptions) and restricting yourself to a subset of the language, as is done with avionics (yes, safety-critical avionics code is written in C++ these days).

    MATE and Xfce are moving to GTK3, however slowly.

    MATE is a fork of Gnome2, which uses Gtk2, so it makes sense that they'd want to move to a newer and still-maintained toolkit. However it may or may not happen; Gtk3 is notorious for bad maintenance, as it's developed and maintained by the Gnome3 devs, and basically they do whatever they want with it, without any regard whatsoever for other projects using it, backwards compatibility, or anything. LXDE ended up converting from Gtk to Qt for this and other reasons. These days, Qt is really the smart choice; it's well-maintained, it does a lot more than just graphics, it's well-designed and easy to develop with, and it's faster than Gtk too despite being C++-based.

    The shovelware is all crapware; on a Linux system, there's just no need for any of it.

    They could pre-install it, but it'd be rather pointless because there's much better free stuff available in a standard Linux distro.

    What companies like Dell could do is make a special Ubuntu version with the crapware running on WINE, and its Free counterparts not installed by default, so that they can get money from the shovelware vendors, and simultaneously not have to pay Microsoft any license fees for Windows. Then they could offer these laptops at a significant discount compared to the regular Win10 versions and still profit. But this idea is questionable: would the shovelware vendors actually pay to have their crapware pre-installed on an Ubuntu system, the way they do with a Windows one? If they don't, or they don't pay nearly as much, then the scheme doesn't work.

    Basically the way the whole system works right now is that you pay a bunch (probably $100) for a Windows license on a laptop you buy, but then you get a bigger discount because the shovelware vendors pay Dell the put their crapware on, and this more than makes up for the Windows license fee. Dell passes some of this savings on to the customer (because the other laptop vendors are doing the same thing, and trying to keep prices as low as possible as it's a tight market). The shovelware vendors do this because there's a chance with every customer that they're going to "upgrade" to the full version of the software, and they'll get a big fee from that. So when they pre-load Ubuntu instead, you save the Windows fee, but then you don't get to take advantage of all the shovelware subsidies, so the price is higher (plus the sales volume for Ubuntu is much smaller, so Dell probably charges extra for that). If the shovelware vendors don't think they're going to get many Ubuntu/WINE customers signing up for their crapware, then they're not going to offer these subsidies to Dell for preloading.

But they missed the boat with Android/iOS smartphones and their apps, and became mostly obsolete. They tried to get into the consumer space but didn't get far there. DEC made minicomputers for big businesses. Businesses just aren't like consumers; they don't care much about fashion, but they are very averse to going with trendy new vendors: "no one got fired for buying XYZ" (IBM, DEC, Microsoft, etc.). Once something proves itself in the enterprise space (even if it's crap) and gets entrenched, it's pretty hard to unseat, but when it does finally become obsolete, or the alternatives are just so much better/cheaper that businesses can't ignore them any more and keep buying from the overpriced vendors, then that company is dead. That's what happened to IBM and DEC, and more recently Blackberry. It might happen to Microsoft, but I doubt it'll be any time soon, though Linux has certainly made big inroads in the server space.
