In working with Perl, Python, and Tcl developers in companies, many have a strong preference for using the ActiveState versions of these dynamic languages. Developers that use ActivePerl, ActivePython, and ActiveTcl appreciate how it saves them time by having easy access to pre-compiled modules through our package managers, and installers for a wide range of operating systems and platforms.
As part of our regular webinar series we are hosting our second technical webinar focused on Tcl. Join resident Tcl expert Jeff Hobbs, Director of Engineering at ActiveState and long-time Tcl community leader and member of the Tcl Core Team, as he reviews Tcl 8.5 and gives a sneak peak into what to expect from Tcl 8.6.
This is the third and last article in the "Concurrency in Tcl" series. The previous postings introduced event handling and threading as possible solutions to the problem of executing several things at the same time, using examples which required basically no communication between the various parts at all.
In the previous article we talked about pseudo-concurrency through events and mentioned threads as one possible solution to some of their limitations. This second article expands on that.
Threads compared to Events
First, in contrast to events, only the C level foundations are built into the core. Script access to threads requires a package: Thread.
So you wish to perform several things in parallel, or at least concurrently enough that the user can believe they are happening in parallel? Tcl supports this in multiple ways, actually too many for a single post to cover, so this post is the start of a small series about concurrency in Tcl. Here we'll talk about events and their management, followed by a post about threads, and finally a post about how we can make the parts of a parallel application talk to each other.
Well, originally I wanted to write down a list of my favorite of Tcl packages and then post about that. But after I wrote them down, I found that this list had only one entry: William Duquette’ssnit.
We're half way through December, and we just wanted to post a friendly reminder about our Season of Giving savings, since the deals end on December 31/09.

Development teams can finally hone their Perl, Python and Tcl programming skills with the new Business Training program ActiveState launched today. There are a lot of benefits to encouraging developers to polish their programming skills.
One obvious reason is that the development team could become better experts in coding with Perl, Python and Tcl. For their organization, this means a couple of things:
