Something like one year ago I switched from Linux to Mac OS X. It was
not an easy switch if you think that my desktop on Linux used to be this one
, that is, just fvmw2 with a minimal configuration, super fast virtual desktop, border-less windows.
Why I switched after more than 12 years of Linux? Actually I didn't
decided to switch, just I got a macbook because I wanted to hack a bit
with the iPhone SDK and with Mac OS X itself. I installed Linux and Mac
OS X in multi boot, and for a few weeks the user interface of Mac OS X
was impossible to use for me. But after a few more weeks I was using only Mac OS X for everything.
For the first time I had a system that was working out of the box
in all of its parts, it was a good desktop experience with consistent
behavior. Screen sharing was cool when working with remote people, no
need to hack configuration files or to check why my webcam was not
working. To try new programs was as simple as downloading the disk
image, opening it, and click on the icon
. And.. as optional,
the system still usable and responsive while it was performing a lot of
I/O! Not something Linux users are used to see.
Note that I'm not the kind of guy that don't want to hack with the system he is using. I even wrote
, my drivers
, in the past
.
But it was years ago and I was still willing to trust that Linux after
all was young and that it was improving in the desktop side. Now enough
is enough, with my computer I want just to focus on what I'm doing
without spending hours trying to fix unrelated desktop stuff.
The strength of Linux, or why Mac OS X is weak as development environment
When I say environment
I don't think about an IDE or
something like this. I used to program with a terminal and vim, and I
still code this way on Mac OS X, so in this respect nothing changed.
What I'm missing are a number of important tools that made the Linux
experience so much comfortable. So here is my list of what's wrong with
Mac OS X, or if you want to read it the other way around, of what is
cool with Linux.
Valgrind
. If you are serious about writing C code you can't live without valgrind
.
Valgrind turns you into a better programmer. The code you produce is
times more reliable after you discover this tool. It is invaluable, and
guess what... it started to be usable for Mac OS X only lately, then
Snow Leopard came and broken everything already. There are patches that
make it barely working with issues (AFAIK things will get better when
the new source code of Darwin will be relased), but, this is one of the
most important tools of a C developer together with the compiler, it
must be rock solid.
Apt-get
. Homegrow, Fink, and alike, are great tools, but
seriously, they are no way as cool as the apt-get in a good
distribution like Debian or Ubuntu. You can find tons of libraries,
full systems, with perfect dependencies, fully managed by people that
are serious users of this projects, that will tell you that something
changed in this new release when you upgrade, "do you want to
automatically fix your old config file?" or things like this.
And... the coverage
of tools is impressive. From
the mainstream to the almost unknown library, there is almost
everything. Want the GD lib for Tcl? There is. Want an old release of a
lib? Sure. Documentation, full application servers, everything. I can
turn a freshly installed Debian system into a production server with
everything inside to run a web application in one hour or less (every
system administrator can). It's wonderful. And guess what? Developers
need to simulate the systems they are developing for, in short time and
without too much efforts in order to be productive.
API stability
. Mac OS X API, excluding the POSIX calls, change
simply too often for my tastes, and there is nowhere the same amount of
information you can find about Linux. For instance I compiled nmap
yesterday for snow leopard, and guess what, it was not working, unable
to open the interfaces. The compiled binary I downloaded from
insecure.org worked against the loopback interface but not against the
wifi one. The interface to capture raw frames from the airport extreme
changed again with snow leopard, breaking valuable programs like Kismac
. It's not an open platform so this changes are even worse.
/proc filesystem
I know Mac OS X exposes similar informations in other ways, but I
sincerely miss the proc filesystem, it was a quick way to explore what
was going behind the scenes without having to remember hard-to-remember
names to grep.
Compiler
. Don't know why but gprof does not work with the
standard GCC (the one installed by the official Apple SDK). Tried to
compile applications with --arch i386 too, still not working. I bet
there is a trivial way to fix it, didn't googled, but it's not OK
profiling does not work out of the box with the official compiler.
This are the things that I'm remembering just now, but there
are more, little problems that I encounter in my everyday programming
experience with Mac OS X that I didn't had with Linux. I still continue
to use Mac OS X as my first development platform because while I code I
also want a good desktop to surf the web, tweet, chat, and so on, but
in order to do my paywork (that's about web development mostly) and my
open source development with Redis I've to use a Linux box constantly
in order to be more productive.
