Exactly!
Seriously:
* binutils/as with really good macro support using `sed`
* zoo of web servers (one's problem if Java version x.y.z.X.Y.Z is needed somewhere)
* Emacs (though nothing more that just text editing is useful in any "IDE")
* bind && sendmail are pride of security holes of past and present (there are alternatives
like exim and qmail for the latter, and some others for former)
* don't know any useful application of zoo of scripting languages except flame wars, otoh i'd
like to have shell be not as it was 20 years ago. Now python 3000 is going to be Java-like,
Ruby runs out of gas (afaik).
* cmake? Oh, man: shell (with one Linux and one libc it's not an autoconf-like mess any more),
ccache (which is 2 time faster shell + sed anyway)
* eCos? maybe, as well as zoo of other abandoned small/tiny OSes
* web browsers? lynx + nc + sed (quite seriously, even for some needed javascript)
* office? in case of bureaucracy maybe, FYI there's only MS there
* X and other useless stuff for what? for global warming?
* php, Tomcat, sdcc (same as above)
* Samba (see office)
* FreeBSD != FOSS, it's a BSD, LSD and such
* Darwin. Don't know, can't say anything
+ mplayer? yes, unless google will open all-codecs-and-file_formats-->ogg
and btw it runs on in pure text-mode using memory mapped framebuffer of modern VGAs just fine
i'd add xpdf (yea, needs X), free console fonts (terminus), inn2, slrn (nothing is hype, but
are very useful).
more importantly accessibility of PDF and web content to simple ASCII + images representations
and no JavaScript/Flash. No w3c handwaving, but real value of information with high SNR.
In case if you are an engineer in architecture, electronics, etc., you will have expensive
proprietary CAD systems, possibly based on Linux kernel and some version of GNU libc. Real
industry is not a joke, handcrafting or religion. Eclipse platform and derivatives doesn't
belong here or they are fancy solutions around basic functionality.
