[lisp-hh] Can't make it the 28th. :(
by Dirk Gerrits 21 Nov '04

21 Nov '04

Hello fellow Lispers, I was really looking forward to the Hamburg Lisp meeting next week. Talking to fellow Lispers on meetings like this always provides a nice distraction from the insanities of my "computer science" education. The subjects of the four scheduled talks also interest me greatly. Alas, I won't be able to attend. :( Not only have I had trouble arranging transportation for the day, but it seems I will be swamped in schoolwork for at least two more weeks. I don't think I can afford missing the better part of a weekend. Will there be any video recordings to ease my pain? In any case I wish those who do attend a good time, and I hope to see you on another occasion. Kind regards, Dirk Gerrits

[lisp-hh] Meeting November
by Edi Weitz 21 Oct '04

21 Oct '04

Moin! So, nach einigem Hin und Her ist nun zumindest sicher, daß wir am 28.11. den Raum wieder bekommen können, den wir beim letzten Mal schon hatten. Den habe ich jetzt gebucht. Nächstes Meeting also am Sonntag, 28.11.04 - 14 Uhr Landesjugendring Hamburg Güntherstr. 34 Wir haben diesmal leider NICHT den Beamer des LJR benutzen. Es wäre daher nett, wenn jemand einen besorgen könnte. Freiwillige bitte vor... :) Momentan habe ich die folgenden Leute als _potentiell_ Vortragende auf meiner Liste: - Pascal Costanza: AspectL - Mario Mommer: (incf ffi) - ein universelles FFI-Framework - Manuel Odendahl: bknr - Lothar Hotz: NetCLOS - Edi Weitz: SLIME-Demo Falls jemand auf dieser Liste jetzt schon weiß, daß er am 28.11. nicht kann, oder falls ich zu voreilig war und er gar nichts vortragen möchte, möge er mir das bitte kurz mitteilen. Danke. Grüße und bis dann, Edi.

I don't think that's necessary. Cheers, Edi.

Maybe we can just switch duties every month or so. If you do it now until the 1st of November, I'll do it in November. Does that sound reasonable? Arthur

Hi Mario, I would do this assuming there are other volunteers to divide the responsibility on. Because some days I won't be interested or too busy. I think things like passwords should be kept to a minimum. Presumably the initial configuration will be trivial, so feel free to give me the password and I'll see how trivial it is.

The situation has improved to the point that the packet loss has dropped from 100% to 45%. Kind regards, Dirk Gerrits

[lisp-hh] Re: [ANN] Erlisp website

Dirk, I wish you good luck. I recommend you to read Matthew Fuchs' PhD (1995) about Dreme. It's Erlang concepts taken to an implementation of Scheme. I'd appreciate a Common Lisp with real language-level concurrency (parallelism?), like in Erlang. The Dreme paper once made be believe a threading Oaklisp with a software write barrier as the basis for a generational GC would be doable on the Amiga (no time to figure it out :) -- Oaklisp also is a byte-code machine. The key was that each thread would have its own 1st generation memory pool, so allocation would be very fast, and copying to the shared heap would only occur when needed, i.e. for message passing. In my simple model, the GC would need to stop all threads (or rather wait until each reaches a safe point, e.g. doing I/O or consing). Each time I suggested adding Coroutines to CLISP, the proposal was turned down because "threads are the real thing". Gilbert Baumann once had coroutines in his copy of CLISP in 1998, but that was never integrated and I fear it's lost. IMHO, threads are not the real thing, because - they cost too much (resources for stack, context switch) - they introduce need for synchronization, where there was no need before. Erlang and Oz schow, among others, that it's possible to express some problems very elegantly using seemingly parallel constructs, but without the need for actual threads. >easier to use and less "low-level" than this industry best practice. IMHO, an approach similar to Erlang's, or also using constrained variables like in the Oz language could be a key to fun/beautiful/readable/verifyable concurrency, as opposed to the thread-stuck, thread-savy and thread-heavy industrial practice. I call the "Smalltalk lie" because it talks about message passing whereas all it's doing is synchronous (blocking) method calls, with all the known problems. Erlang does real message passing in my words, because the senders and receivers are autonomous. Although I have followed the evolution of Erlang for several years, I sadly haven't used it in a project. I tend to stick to single-threaded applications using CLISP, Kawa (Scheme in a JVM), or use Python's coroutines here and there, longing for a better world. [BTW, isn't there a better place for this than 3 mailing lists?] Regards, Jörg Höhle.

[lisp-hh] Too many mailing lists
by Pascal Costanza 14 Oct '04

14 Oct '04

Hi, We definitely have too many mailing lists. I have got three copies of each posting in recent discussions, and that doesn't really help to keep track of what's happening. We already had a brief discussion, and I think a consensus, that a European Lisp mailing list would be great. In order to help that mailing list become a reality, I can offer to write an introductory text for the respective website. (I would prefer a Wiki-style website so that later on people can change the text or, for example, translate it into French and other European languages.) If other people can take over the responsibility to set up the mailing list and later on promote it on the various channels, we should relatively quickly be done with this. Any volunteers?
