The next meetup will be on 6 January 2009. That's the first Tuesday of the month. I finally got around to updating the wiki with Abram's notes (thanks for those). Added links to them too. Anyone (or two) willing to do a presentation in January? -Rudolf O.

[toronto-lisp] My notes on the recent meeting
by Abram Hindle 03 Dec '08

03 Dec '08

Here are my toronto lisp users group notes. The topics are expressed in rough order of appearance. Sorry no hyperlinks right now. * LISP Meeting <2008-12-02 Tue> Overall the meeting was about communication, semantics, lexicons and models. Oh with a real lack of syntax (use sexprs) unless we need it. Gary probably led most of the discussion. How does this relate to LISP? Sexprs and expressability. *** Concurrency -> Expressability of Lisp - The language problem - ORC - stratego - programming rewriting - TXL etc - issue of performance - Adoption - low level lisp - sassy - assembler and scheme macros - call out to scheme - siag - scheme in a grid - proto scheme - natural language ??? - legalese - semantics - grammar - lexical - more semantics - more semantics - back to concurrency support - call return - grammar - did I mention semantics *** Convienance - Prolog to lisp and vice versa - erlang - concurrency convienance *** GUIs - Book: Humane interface - jeff raskin - ... missed some *** Visualization -> Diagrams - studies - communication - diagrams have limitations - discussion - making diagrams - executability *** Tree structured program - Book: Design Driven Design - macros are semantics independant - why bother making the syntax - work on semantics - SE & Tree Structure - Tree Specs - Executable specs - formal specs? - formal language for specs? - use sexprs - human translation to - formal?? - paraphrased: - gary says model driven design/arch/spec - fails due to a lack of lisp? - Elegance versus symbolics - nice drawings mean - problem is defined - once you can winnow SE down to diagrams - you're a real engineer - Book: Realistic Compiler Generator from MIT Press. *** Meeting Ended *** people in attendance - abram - brian - paul - justin - james - chris - gary

[toronto-lisp] Next meetup. Tuesday December 2nd?
by Rudolf 02 Dec '08

02 Dec '08

That's the first Tuesday of the month and that's what everyone seemed to agree on is a good date, right? I'm going to miss it again because of an exam :'( On the plus side I've been checking out the Processing language because of the course and wrote up an Emacs mode for it. -Rudolf O.

That's exactly what I was interested in knowing (in two senses: knowing that someone who knows some Clojure would be there :)#). I might print out (I'm between laptops) http://clojure.org/{concurrent_programming,refs,agents,other_libraries} and bring it to spark some questions for me. I'd also be interested in "getting started" type information that fell through any cracks in the documentation. I'm also interested in it from the perspective of using it for teaching courses that might traditionally use C or other specicalized concurrent, parallel, etc languages. [...]

I completely missed the discussion that set the first Thursday of the month to be the Toronto Lisp User Group meeting date, so I don't know if my question is ridiculous (e.g. akin to arguing about editors): Is it possible to consider another day for the regular meetings? I have a conflict with the first Thursday of the month (Royal Astronomical Society meetings on the first Thursday). Other Thursdays are good, and Tuesdays are good for me. If the day can't be changed, then I will simply have to choose to skip some meetings, when I wish to attend the RASC meetings. pt

Can someone (or two) give a summary of what went on? What was the presentation about, what was it like? Are there slides that can be viewed online? Sorry for missing out, I thought the cold I had would be destroyed by meds by 5pm, but nope :-/ -Rudolf

[toronto-lisp] Horse play
by Brian Connoy 19 Sep '08

19 Sep '08

Hi all, I have reason to believe one of the VB/C# pilots here at work, is going to jump ship. As well, a supporting contractor is on his final day today. In short, they are likely to be in a pinch soon with their in-house VB/C# development efforts. So why am I mentioning this here?!? My aim (as mentioned at a couple of the meets) is to lay the ground-work of a "Lisp shop". They don't know it yet, but Common Lisp is going to be their secret weapon. Although I don't play a role in the developments mentioned, one way to broaden the Lisp base is the 'ole Trojan Horse ploy ... a Common Lisp programmer smuggled inside a .NET horse! Interested equestrians are welcome to contact me for more details. BC
