+1. Yeap. You are on track, guys! The whole point is, that even if when we are involved commercially in a project, it's optimal to promote the usage of open source software anyhow, as a matter of enhancing community effort and investing time in a manner that you can benefit from it many times more in the future. Kudos.
OP here. Your concern is very valid and you are not alone, I have the same concerns.
However, at the moment we know of no other standard that actually renders alike among zillions of Desktops, smartphones, automated processing agents etc.
Can you really replace.pdf format with something of similar functionality AND not ask the majority of users to install X, Y, Z?
Sorry to be cynical, but here it goes: Next time your smartphone slows down horribly or plainly crashes, remember the above words of you.
It's how this game is played by you guys, yet all systems people frown upon the concept of "wrap around software deficiencies by buying more hardware"...
I also find inappropriate a similar recent evolvement within IEEE politics; in this case it relates to LGBT rights, see for yourself:
http://www.hrc.org/blog/entry/...
To be sure, LGBT rights are important and it is good that laws protect them - and more could and should be done about it.
The same applies for Human Rights, overall; no person in his secular humanist mind would ever object to that.
It is doubtful, though, that LGBT groups would ever add banners in their statutes in relation to engineers' rights and ethics,
so it is questionable why the reverse should ever be true. There is really no point in adding pompous statements
in relation to sex, sexual orientation, skin color, disabilities etc. Making such a list is itself a kind of discrimination (!),
since you hand-pick which kind of discrimination is bad, as if similar non-professional conduct is any more tolerable.
Sorry, that's not correct and, it's even not fair for those who really cherish a generic concept of citizenship
and may get discriminated for a reason not declared in the list.
Please, guys from the US, let's keep the focus on what the original subject is and, avoid making professional bodies
appear as vehicles for (valid) political ideals, which distract from the original cause and warrant conflicting agendas!
And if somebody goes against constitutional mandates, the juries are there to put things in order.
ACM carries a historic name, but subscriptions cannot justify buying just that. IMHO, most techie people do try it out and then have their memberships lapse.
I've been managing systems with hundreds of well-meaning and not-so- scientists, for years.
Generally, I subscribe to the school of thought that putting too many fences does more damage than good.
I know for myself, that I *can* create trouble in a zillion of ways on a system, that fencing against it is almost pointless:
* fork bombs
* malloc bombs
*/tmp overuse
*/dev/shm overuse
* deliver daemonized processes in the background
The first two you may handle a bit with the PAM limit techniques described by a fellow poster, but not without limiting the capabilities of the system (ie. you take out useful features, to enforce some policy). The rest you can attempt to handle with some other clumsy fencing techniques, but again not without side-effects.
In short, do not overengineer, yet be totally reactive: let the rules be relaxed in the beginning, monitor tightly, react quickly and be sure to have often your users at the other end of the phoneline/email justifying their tasks' activity. You'd be surprised how much you'll discover by doing that and policies will be far more justified.
> One thing that shouldn't be underestimated is the ability of a user (especially a young user) with *lots* of free time on his/her hands to figure out ways to game the system...
Also this!
Young users with lots of free time will give you a headache, one way or another. But you can often stop them by just blinking an eye.
To begin with, I'm a Pythonista for much of the time. Even so, I can see how you will probably land in the world of R; here is why:
* R comes with reasonable facilities for statistical processing and, on top of that, has important extensions that allow for remarkable features. Example:
Setup R language, with snowfall->snow->Rmpi extensions. The result of this would be *fault-tolerant* *scalable* code, within relatively simple codebase.
It cannot be overemphasized how much functionality you get out of the box in such setup, with basically zero code changes (in R).
* Python is great when it comes to integration with other languages/codebases. It could well be the best scripting language since... the invention of bread.
As another poster mentioned, it can also interface with R via Rpy, so it's not at all a black-or-white decision.
In short, both are first-class tools for scientific computing and you should compare and choose them on technical merits basis.
In case you are in position to help as the article suggests and,
you just need a little kick to get you in action, watch this one:

The biggest reason of interest is that it helps non-computer-science scientists write up computational codes, neither having to devote excessive amount of time in memory management, nor deviate from the classic imperative programming model. And, it is also important for a purely non-technical reason: a generation of domain experts in engineering and scientific domains where trained in FORTRAN codes.
As managers of High Performance Computing platforms, we generally take an a-religious approach and deliver to the users all possible permutations of language types that a given community may need. The following is a very common setup, containing both GNU & Intel compilers:

IFF you have even done wget/tar xvf/patch/make/make install - and wondered,
if this process could be ever improved and make sense, you have found your project!
EasyBuild allows you to tame scientific software of the following type:
* Download and build GROMACS over FFTW/3.3, applying patches X,Y,Z, using CUDA for speed.
Probably all you are missing over there are scheduled maintenance windows.
You give them a list once per month about what is about to change, get a confirmation, proceed with them available on standby for fixes on the spot or, rollback.
Try to think the big picture: how would you maintain the systems, if they were life-supporting medical equipment? Why not give same quality of service?!
OK, the rope won't do as much for accuracy as actually working out the math a bit, but nevertheless it WILL be better and more guaranteed result than a shotgun.
Also, if you can curry a shotgun for the post-apocalyptic world, you can as well carry a clay tablet with "355/113" written on it and save on the bullets for the moments that you will be in higher need... (having a monopoly on circular constructions might make you a highly sought target:-P )

The other Greek fellows that wrote around this article, I'd say that they portray well the different standing of opinions of the greek population at large, and even hint at the cause-effects of this "legal accident".
Most points are valid as opinions but I'd rather emphasize a couple points for clarity:
> In school is surely optional to pray and to attend the one hour per week religion class.
I'd differ in that: at the time I was in high school, the courses about religion WERE
compulsory to attend and formed part of the final grade. So, it is a form of coercion.
To be fair, most teachers had enough intellect to let things go by without mishaps.
> That "hold of the church over the state" i can not see it - i don't claim that you are lying but you exaggerate the situation.
Hm, we all wish it was the case: Few years ago my father made the claim in a related family debate,
that I am a citizen of a theocratic state. Of course, I gasped at the notion and refuted.
How wrong I was! the first line of the modern greek Constitution starts with: "In the Name of... Trinity" ! eh!!!
The only think that consoles me is, that our occidental neighbor, Italy, needs to make even more steps for state-religion separation:)
