Re: Can't install MySQL driver

> a bit off topic: I wanted to use GOODS with Seaside, but have had not > enough time to make GOODS server runnable from Squeak on Linux > (currently the server package is built for Windows only, with notice > that "it can be rewritten for others using OSProcess"). Let me clarify. First, GOODS server can be run outside of Squeak. It is just an executable file. I'm sure you can download and build GOODS from http://www.garret.ru/~knizhnik/goods.html. Then just run the goodsrv program outside of Squeak. GOODS client is still necessary in Squeak to access the server. The GoodsServer package for Squeak was written because I was tired of doing just what I stated, e.g. starting goodsrv outside of Squeak. I just wanted to launch it from my program in Squeak. I wrote it with only Windows in mind, but in the latest edition on SqueakMap, I included a contribution from Marco Paga <marco(a)marco-paga.de> that provides a Linux compatible version. I don't have Linux so I cannot tell you if it works or how to troubleshoot errors on that side of the equation. I should update the SqueakMap documentation to reflect this.... Regards, John

May I suggest making the results available even to those who have not / could not participate? As an example, I am an educator and would like to share these results with my students and colleagues. Ivan Ivan Tomek School of Computer Science Acadia University Canada -----Original Message----- From: squeak-dev-bounces(a)lists.squeakfoundation.org [mailto:squeak-dev-bounces@lists.squeakfoundation.org]On Behalf Of Jeff Eastman Sent: Monday, August 30, 2004 8:28 PM To: squeak-dev(a)lists.squeakfoundation.org Subject: Smalltalk Market Research Windward Solutions is conducting a research project to understand the current Smalltalk market and how newer technologies such as Java and the Web are impacting customer commitment.

If you have recently worked or are working in the Smalltalk space we solicit your assistance. We have posted a brief market survey at ( http://www.windwardsolutions.com/smalltalksurvey.htm), and it should not take much of your time to respond.

Of course, you can use the ODBC package and install a MySQL ODBC driver. I use this to access MySQL and SQL Server in my job duties (on 3.7). > And if I want to use a serious relational database with the current > image it would have to be PostgreSQL, right? Or any relational database that provides an ODBC-provider -- which would be all the serious ones (and some not-so serious ones). > Which of these approaches do most people use when they want to use a > database with Squeak? Or do people use databases with Squeak? We do a ton of work with databases and Squeak 3.6 / 3.7. That's all I do! Select this, insert that, delete (whoops)....rollback > I know I could consider some kind of object oriented > database like GOODS, but that seems to offer only persistence, not the > automatic indexing and fast searching on any part of the data that SQL > databases can do. We also use GOODS quite a bit when we have options to be more efficient in our development and not bridge the object-relational divide. Of course, with GOODs the onus for indexing rests with you (e.g. keep the necessary maps as objects in the database as well). Indexing is easy (with dictionaries or btrees), but the more general problem is keeping your indexes up-to-date. GOODS supports fast searching if you utilize the indexes you already have (like relational databases) -- and it is slow if you perform "full table scans" (like relational databases). Regards, John

from preamble: "Change Set: WantsToBeTopmost-Refactor-dgd Date: 31 August 2004 Author: Diego Gomez Deck Generalization of the already implemented mechanism to promote flaps to topmost objects. This new method will allow other type of morphs but flaps to benefit and become topmost citizens. For instance, a DockingBarMorph like http://swiki.agro.uba.ar/small_land/uploads/234/menubar.png can share the benefit. " !

kernel, Squeak and memory
by Jan B. Krejci 31 Aug '04

31 Aug '04

Hello, After I have installed kernel 2.6.8-1.521 to Fedora Core 2, Squeak encounters the high memory problem again, according to Ned's probe script (and my eyes :) ). Using older kernel 2.6.5-1.358 and -mmap parameter, it runs OK. With the newer one, even -mmap parameter does not help. Any idea? Is there a chance that recompiling the VM with new kernel headers may help? Regards to all brave Squeak heros! .:jbk:. Jan B. Krejci
