Hi everyone,

things have been rather distressingly quiet the last couple of months. Nobody to blame but myself, mind you. I'd like to put together a more structured meeting than we've had for the last little while, but I'm going to need some help and a bit more time and organization. I have rather a lot more time on my hands these days, so I'm gung ho to invest some of that time in revitalizing this group.

I think this month (May) we'll have an informal Maude's meeting, and I'd like to spend some time hearing about things people have enjoyed in the past, or things that you'd like to see in the future. Also, I'll be recruiting people to present on subjects, so think of something you want an excuse to read up on and volunteer!

This month's meeting will be held at Maude Hunter's, at 7:00PM, May 5th (the first Tuesday of the month). If you're new to the group, you'll be able to recognize us by my dorky sticker-festooned Mac laptop on the table.

See you all there,
-pvh

Hi Peter,

I'll try to come out to Maude on the 5th. This should be possible, as
I'm back in town on the 4th.
In terms of future talks, I'd be willing to talk on a big array of
things - hopefully we'll get a chance to discuss this on the 5th :)

cheers,
Grigory.

I can't make it. I'll be at BSDCan in Ottawa.

I like the tech talks. Maude's sounds good, but could we have the
usual tech talk with blackboard first? I've got something to
volunteer: I recently use Perl's Parse::RecDescent to make a little
SQL-like language parser for a database report generator. I thought
Darren might be interested in something to use for Muldis.

Yes, I would be interested to see this talk of yours. I could learn something
from it or possibly even adapt your code directly.

Meanwhile if you have any written material about your project to peruse, please
post it.

P.S. I did just, after the posts about code samples, release another update or
two to the Muldis D (v0.64.0) language spec (with further updates in VC but
unreleased), and also another corresponding release of the Set::Relation
(v0.10.0) module. The latter features short-hands for the common desire to
rank/order/limit simply in terms of a list of attribute/column names to order
by, saving the relative verbosity of having to define a higher order function /
closure that the general case of sorting in terms of arbitrary value expressions
requires. It also features a short-hand for the analogy to "select ...,
count(*) from foo group by ...", saving the relative verbosity of a hof/closure
that the general case of per-group aggregate operators requires.

P.P.S. Hmm, perhaps I have now just been inspired to add another, more general
short-hand function for using other aggregate operators without needing a full
closure for per-group aggregation as summary() does; it would take an argument
that is a set of attr-name-src:attr-name-new:agg-func-name triples. Or maybe
that's overkill?

Wow! Awesome, yes, absolutely. I just didn't want to nettle people into giving a talk on such short notice given that I didn't really have anything in mind to talk about myself.

In that case, I'll send out a proper meeting announcement next week then if we'll have an actual talk. In fact, now that I'm thinking of it, I'll chip in and give a short talk with examples on interpreting the SQLite VM bytecode since it is so beautiful and lovely in its own special way. It's really actually quite interesting and accessible. Hell, I figured it out.
