All the studies i checked (sorry no ref, that was 15 years ago) on the subject correlated closely drops of burglary with increase of outdoor lightning in the same area.
But why not explore other sources of lighting? glowing plants for example (they had some success with kickstarter a few months ago)
Red Hat (and the Fedora project) is trying to prevent the balkanization of Linux userspace with projects like systemd, which only Ubuntu rejects.
Only Ubuntu rejects systemd ? As far as I know only three distros adopted systemd so far: Fedora (after all it is developed by their community), Arch (as it tends to rush toward shiny new anything (not necessarily a bad thing)), and OpenSuse (I don't have really any satisfying explanation for that move). Fedora is RedHat's testbed, and they've been known to drop tested techs before inclusion into RedHat.
From my point of view, the only project "balkanized" by systemd is GNOME, I don't get why a Desktop Environment would consider a hard-depend on a specific init daemon (if systemd can still be considered that, after including an httpd, some qrcode libs and a hard-depend to dbus).
It sounds like plain biochemistry given a new window dressing.
Not exactly... there's actually something new here (2-3 years old in fact).
There are 3 "levels" of Computational chemistry :
- ab-initio method : a resolution of the Schrödinger equation for the studied system with only a few approximations mandatory to solve problem more complex than the hydrogen atom. This method is fairly demanding on number crunching power and is applied on models of hundreds of atoms.
- semi-empirical method : this method is based on the Hartree-Fock method used in ab-initio with the inclusion of approximation issued from experimental data. This method is applied on models of thousands of atoms.
- molecular mechanics : this method uses drastic approximations in order to obtain a Newtonian system (linear system of equations). The major drawback of this method is that it does not allow chemical reactions, but conformational changes may be studied in solvated systems. This method may be used to model system of 100.000s atoms. This method was mainly developed to study biological systems (a middle sized solvated protein gives a system of 100.000 atoms) because a lot of biological phenomenons may be explained conformational changes (life use the "soft" chemistry beautifully).
However some biological mechanisms still involve some chemical reactions, and to describe those using today's computing power some techniques were developed in order to mix molecular mechanics and semi-empirical methods. In order to observe a localized reaction, only a small subset of the system is solved using the semi-empirical method, the remaining is solved using molecular mechanics. This is what is presented in the article...
This technique (QM/MM : quantum mechanics / molecular mechanics) was described and used as soon as 1995 but its use increased during the last 3 years due to the availability of the mandatory computing power ( http://scholar.google.com/scholar?q=qmmm&hl=en&lr= &btnG=Search ).
QMMM is not new, but its application field is widening...
The tools I was referring to were parts of the Mandrake control center.
What I wanted to say is that those tools do not cover all the options of the config files (/etc), they only propose "the most used one". The problem is that those tools often consider to be the only process to be allowed to edit those files and crash if they found out that the file was manually edited.
What I think is that these GUIs are great as long as you use only them. But what i like in Linux is that you can fiddle everywhere so I prefere not using them.
I remember a "samba configuration tool" which systematically destroyed any manual config done to/etc/samba/smb.conf and that was not allowing the a proper config... as the computers were given to others to use these tools had to be disabled in order to avoid any : "oh what does this pretty icons do?" click "Answer : wreck havock in your network shares!"
There were also some really funny (the 10 first times only) videocard detection tools that would keep on bringing back the options they wanted me to use (it was on a stereoscopic system and each time I was connecting a second display the detection system would remove the stereoscopic options....)
There is a magic word : dcc
Stand for "Distant C compiler" if I remember well
This dcc interface itself with the portage system allowing to compile on several computer at the same time.
It is also available on certain mod of knoppix and on the gentoo livecd.
This is the perfect solution for old hardware.
Those two are pretty different :
Mandrake is designed for the newcommer or someone who want to install a system in less than 30 minutes without being bothered by hardware problems (autodetection wizard). The obtained system is quite rigid and require to enjoy GUI config tools (cause some of them cannot be bypassed).
Gentoo is tailored by the user himself which results in a longer installation (can be up to 2 days) process, and a minimum of automatisation (some kind of autodetection but you are encouraged to avoid it), all this in order to get the system you want (ie most of the time faster than any precompiled distros).
To compare distros with cars Mandrake would be an easy to drive automatic and Gentoo would be a custom car...

Furthermore, having glanced over systemd sourcecode, I wouldn't consider it maintainable for the time being (it is a hardcoded feast ... https://plus.google.com/107219817074938512538/posts/PiJKFD49RUW for a few examples).
i like that one too: "If you make something idiot-proof, the universe creates a better idiot."
