Yeah,it's incredibly easy just to offload loops or whatever into Fortran and just use F2py. As an aside, Fortran 90 is just about as easy as Numpy or Matlab, so it do 90% of my work in there. I just use F2py to compile my Fortran modules as Python modules. Then I have the flexibility of using an interpreter with the speed of Fortran.
I haven't used it, but PyPy is a very fast JIT compiler for python to speed up native Python code.
Why teach a crappy, relatively more difficult language like Java to children?
At least teach a hard but good language like Haskell or C.

Drives me crazy. At least with statisticians, R is by far the dominant package now. But in science, it's Matlab Matlab Matlab.
Python + Numpy/Scipy is such a better alternative now it's not even funny. It's actually a real language, and has loads of packages. And unlike Matlab, you don't have to pay extra money for additional packages (or any money).
The use of closed source software in science is a waste of scarce resources, and it hurts openness. Another thing is that every numerical type class I've had has used Matlab. It's really unfair to expect students to purchase a copy. I use Octave when I have to deal with this, but it is not perfectly compatible.
It's really different use cases. In practice, Arch seems to give a smoother desktop experience with minimal screwing around. It's pretty rare to have any sort of breakages, as long as you keep an eye on the website for any big changes. Security fixes are available immediately from upstream as part of normal updates, of course. Perhaps it is just my experience, but I just see more rando bugs with Debian than most other distros.
RHEL or Debian stable is probably better for an actual production environment. They are more stable in terms of API stability, but not necessarily so in terms of kernel panics, etc. Arch is bleeding edge, and things change a lot. That said, it gives you the newest stable packages that are current in terms of security and bug fixes. Sometimes this doesn't work out, as in KDE 4.0, but it's usually a good thing.
Debian Stable is certainly not up to date, and I've always had problems with lots of random bugs whose fixes haven't been backported. Sid is the only way to get modern packages, but it's an absolute clusterfuck. Ubuntu/Mint are nearly as bad, but they do clearly put work into making sure the desktop experience is relatively smooth.
Arch linux on the other hand has bleeding edge STABLE packages. I almost never have any issues. Arch packaging are typically very vanilla. Heavy patching like Debian does introduces a lot of problems (ie in urxvt). Upstream generally knows best. They wrote it.
Even at my large research university I still can't get access to a huge number of journals. My advisor, for example, literally does not have online journal access to some papers he has wrote.
And my Comcast internet is limited to 300 Gb/mo and the speed sucks balls. Most people are in fairly similar situation. A "cloud" drive ain't that useful. CLOUDS!
Netbooks used to be cool but they almost invariably have the same 1.6 Ghz atom and 1Gb of ram that they did 5 years ago. And they are actually more expensive than they were 5 years ago. 1 Gb is ok if you use LXDE or Openbox and don't go too wild with firefox tabs, but it kind of bites.
Upgrade the screen to 1366x768 and give it 2Gb and I'll bite, though. It really sucks that there apparently is no market for cheaper =12" laptops. The 1024x600 is usable once you get used to it, but it's never good.
In addition, starch-based plastics don't actually degrade any faster than petro based ones. Plastic bags will distinigrate relatively quickly, but they degrade into microplastics, which have a variety of negative effects on marine life.
The real problem with plastic is the creation of plastic marine debris. Plastic bags are the #1 source of plastic marine debris, which is quite harmful to ocean life.
I spend far less time dealing with retarded bullshit on Arch than on Ubuntu. Far less breakage and pacman is much faster than apt get. It takes longer to initially set up, but you get a system configured how you want and you don't have a cluster fuck update every 6 months.
Ubuntu has a lot more bugs and quirks, both from using unity and by heavily patching upstream packages.
Okay, if it is being propelled from just thermal emissions, it would need to be much, much hotter to provide thrust on the order of millinewtons. Photons have momentum, but it's really, really tiny. You need hundreds of megawatts to get just one measly newton of thrust. And that is not the mechanism this guy is claiming.
Scripting languages are always, always vastly slower than compiled languages like C or Fortran. That's why they are often used as "glue" languages, and you never want to do big loopy things in them.

Over half of the population is way too dumb to understand programming in the first place. It's better to start off with a good language.
Also, C is easier than Java. C++ maybe not, but then it sucks balls too.

These guys really can't think anything through.
Actually, pharmas spend more on marketing than they do on R&D now.
Christ just download Xubuntu instead.

And with the software as old as Archimedes.

That's just not true. Plastic bags are made from polyethylene the vast majority of the time.

There seems to be a troubling trend of people outside of STEM disciplines being gullible morons.

That's why most CRT monitors refused to display out-of-range signals. The ones that didn't have this protection had a shitty design.
Freenx is a great solution for less shitty X11 forwarding. It compresses and caches stuff and doesn't need nearly as much bandwidth.
