Being developer with a scripting background and recently delivering
products for Windows as well, I am constantly amazed at the incredibly
shoddy quality of the basic Windows utilities.
For example, try the following stuff in a batch file (without using
"echo off") and place a directory "something" in one of the places
where this script will look for it
if exist something\NUL goto havehome
for /D %%I in (.. c: d: c:\* d:\*) do (
if exist %%I\something\NUL (
echo Picking the installation in %CD%
Note that as opposed on the command line, one needs to double some
percent signs. Note that %CD% echoes a wrong value, but one can't
write %%CD%% since that is echoed just verbatim. Note that the
execution echo of the for loop command is _mangled_ at the front.
"Windows can't be too complicated to support" is a sentiment for those
who have never tried it. For us, supporting Windows for what amounts
to be a _working_ console application, has proven to be a terrible
resource drain, tying developers into absolutely ridiculous fiddling
In a similar vein, making AUCTeX support Windows installations has
been tying up a lot of resources (most problems stemming from path
name differences) that were not anticipated up front.
Currently I have the problem that Windows barfs at one of our
customers because of too many open files (512 or so). There are no
documented limits for tuning I can find, and I don't even know where
How Microsoft managed to become a "platform of choice" is certainly a
marketing feat second to none. The system as such can only be
described as mostly unusable, unmaintained and unmaintainable in its
most basic parts.
