Re: st: Re: choosing between sj and ssc...one more thing
A few comments I will add:
HOWEVER Stata's "net install" facility was designed to
specifically prohibit that action. Files referenced in a Stata
package file must live on the same machine. That restriction is
not technical, but security-driven; in a world where many authors
can no longer email me a 'foo.hlp' file, even in zipped format,
Stata's security constraints are surely appropriate. Thus the
necessity for anything "SSC-able" to live on the SSC server here
at BC. But I should remind authors of SSC packages that while
setting up a package entails some work on my part (less for a
second, third... package from the same author), updating the files
within it (and the package's distribution date) takes a few
seconds, with drag-n-drop.
* If you are going to maintain your own site, please try to match the
quality of SSC's documentation in your pkg file. In particular,
include the distribution date, so that adoupdate knows when you have
a new version available.
* Try to avoid having multiple versions of your files on separate
sites. It gets confusing when you see the same program name at
different locations and you don't know which is the most current or
even if they are the same program. If you ever submit your program
to SSC, make a point of making sure it always has the latest and
greatest version of your program, since (I suspect) many people are
going to go with SSC if there is doubt as to which version to use.
* SSC will not let you submit a program whose name is already in use
at SSC. So, if you maintain your own site, first use findit to make
sure that your program's name is unique. Keep in mind, however, that
people submitting to SSC are not obligated to avoid your program
names if your program isn't on SSC.
* I do sometimes make beta versions of my programs available from my
own site. When I do that i give the programs slightly different
names to avoid confusion with the officially released versions. I've
found that using net install is a far more reliable way of getting
programs correctly installed than just emailing your program to
somebody; even smart people will find ways to make mistakes!
* Rightly or wrongly, I tend to trust programs from SSC more than I
do programs from individual user sites, at least when I don't know
the authors. I figure Kit maintains the site well and insists on
some minimal standards with regards to documentation. You also get
usage statistics from SSC which can build (or bruise) your ego.
* Nonetheless, there are some great individual sites. For example,
I've always admired the way Roger Newson keeps old versions of his
programs around for those who are not fortunate enough to have the
latest and greatest version of Stata.
