Re: [racket-users] Rosetta Code: Level 1st (that's FIRST) with TCL
Great news!

I took a quick look at: * http://rosettacode.org/wiki/Category:Tcl and * http://rosettacode.org/wiki/Category:Racket And they both have the line: The following 845 pages are in this category, out of 845 total. I *think* that means that both Tcl and Racket have 845 tasks impemented, but short of walking down a printout with a pen (and it's far to late to be doing that) -- I do believe that Tcl and Racket are now jointly the most popular programming languages on Rosetta Code. WELL DONE AND THANKS TO EVERYONE WHO HAS CONTRIBUTED (especially Racket) CODE ONTO ROSETTA CODE! And many, many thanks to the Racket team for producing a language which is now demonstrably as competent as any. (Although we all knew that before anyway, didn't we?)

Perhaps one (you) could make a task demonstrating how to make new binding constructs? /Jens Axel 2015-04-29 12:44 GMT+02:00 Stephen De Gabrielle spdegabrie...@gmail.com: Are there any tasks suitable for Rosetta Code that are difficult or impossible in other languages like Python or TCL?

Re: [racket-users] Handling concurrent requests in the web server
Hi Tim, I ran an experiment to test your servlet. The results are at this gist: https://gist.github.com/jeapostrophe/f7fd1e48be19300b7b15 You'll see that I ran it with serve/servlet, benchmarked with % ab -n 50 -c 5 http://localhost:9000/test 21 | tee ab.log and that I got the expected number of 5 concurrent requests serviced at a time. There is a bare possibility that it is working on OS X/my machine and not on yours, but I am more suspect of how you tested concurrency.
