Re: Domain Specific Languages?

We had a new coder join the team and he said he found it pretty readable. There's also some degree of support from the IDE (eclipse) -- although you always lose infrastructure when you go meta. We've had some (heated) discussion about how much we should code stuff up in "straight" Java, but my feeling is that once you get serious about removing duplication on a task like this you end up going dynamic anyway. The hard parts are: that designing a language, embedded or otherwise, always takes effort (and I'm frustrated at not having enough time to make the structure as clear as I'd like); that it's a fairly messy domain, so writing something really clean may simply be impossible. For those who are familiar with the relevant history, the current syntax is kinda half-way between the old dynamic mocks and jMock. We haven't quite made the AST clear, and have a lot of helper methods in the classes where we build up the rules. S. M3P Limited ------------------------ Yahoo!

[ANN] Pimki 1.8.092

Hi All, Am very happy to announce a new release of Pimki: The Wiki-based PIM to GetThingsDone! Pimki 1.8.092 is a maintenance release. It contains many small (and a few not-so-small :) bug fixes. Important note: this release is still based on Instiki 0.9.2. You cannot use Instiki 0.10.x snapshots directly. Snapshots from previous versions of both Pimki and Instiki should work fine. The next major version - Pimki2 - is now in alpha testing phase. It is fairly stable. A few features need more polishing, and the main issue remaining is integration with Instiki's still-under-development SQLite backend. Go to http://pimki.rubyforge.org for the full scoop. If you're running gems just run 'gem install Pimki' and it will be installed/upgraded for you. Otherwise just download, unzip and run! Cheers, Assaph ------------------------ Yahoo!

Re: Re: log4j

I've been using the log4j for the past several years in all my applications. Here are my suggestions. Never use commons logging. Log4j handles every logging need you could possible need. Common Logging is just a pain to use, because it is nanny type tool that thinks it knows best. Commons logging is also why it can be a pain to get log4j to work right in appservers. To my recollection only log4j gives you email appenders and support nested device contexts. These are two great features for web applications. I have email appender send me error messages from my web applications. NDC act like a stack. I push the domain or the user on the NDC stack. This way each message also tells me who the user was. ChainSaw works with both the XML file or a port. If you use ChainSaw with NDC stack, you can filter you log messages to a domain or specific user. You can also just use a Perl/Python/Ruby script to filter out the messages from your log.  If you are working with a remote server using the port based ChainSaw can be pretty useful, but most IT groups don't want to open up the port.

No. It's been a while, but I think the more common usage is to connect to the monitored app through a socket. I can't remember the name of the appender right now.

No. It's been a while, but I think the more common usage is to connect to the monitored app through a socket. I can't remember the name of the appender right now.
