A Full Allocation Rate
by guzdial＠cc.gatech.edu 08 Jan '98

08 Jan '98

This is mostly to Ian, but others may have advice or be interested in the answer: Ian, I'm using your SystemMonitor (startFull) on several of my systems, and on one, I'm maxing out the "alloc" (allocation rate?) bar. What does that mean? I know what maxing out the memory means -- buy more memory, allocate more to Squeak. What does maxing out allocation mean? Thanks!

#isInteger
by sqrmax＠cvtci.com.ar 08 Jan '98

Hi. The method #isInteger is implemented the same way in Object and in Number. Is there any reason for this, like forced method caching or so? Shouldn't all the isSomething methods be implemented in Object as well? Andres.

Re: Swiki in NT?

We're going to try this ASAP. THANK YOU SO MUCH!!! I *really* appreciate your digging into this! Swiki's have taken off here at Tech much faster than I expected -- we have *FOUR* classes using them, with three other classes requesting them, plus four more being used by various research groups. (Why? Ward's Wiki is just a marvelous idea, and Swiki is cheap and easy to run.) I'm running out of server capacity!!! Moving to NTs will help alot. Many thanks!

Good stuff! Saw that you are thinking of a user interface where the class hierarchy browser and file browser look the same. Perhaps the work I'm doing is of interest- http://www.canis.uiuc.edu/~tyrrell/Oasis/Preview/preview.html This is a boilerplate testbed. It's not meant to look pretty, it's just to get the underlying infrastructure worked out. This is not the only way this system could appear- in fact, the two views shown are both generic, independent of thier contents. The contents, not the views, determine the "application". This is one of about a dozen "applications" currently using various incarnations of this same infrastructure. Les Tyrrell tyrrell(a)canis.uiuc.edu

bug in someInstance (?)
by Frank Zdybel 07 Jan '98

07 Jan '98

I don't know whether this has already been fixed in subsequent versions of Squeak, but as late as v. 1.2 primitiveSomeInstance had a bug in it, to wit in the event of primitive failure the imple- mentation did not restore the state of the stack properly by re-pushing the original argument. frank

Georg Gollman has his Squeak WebServer code available at: http://ftp.tuwien.ac.at/~go/Squeak/ Another Squeak webserver is Tim Jones' WebTalk, but you would have to get it from the Create FTP site (which has been down several days) or Tim at tim(a)thregecy.com . -- Dwight -----Original Message----- From: Mike Klein <mike(a)twinsun.com> To: squeak(a)cs.uiuc.edu <squeak(a)cs.uiuc.edu> Date: Tuesday, January 06, 1998 3:30 PM Subject: Re: Web Server | |> From vassili(a)objectpeople.com Tue Jan 6 06:41:34 1998 | |> Hi Mike, |> |> The web server is at CREATE (and probably other Squeak archives) under |> Applications.

Web Server

I heard that there was publicly availiable web server code for squeak. Anybody know where it is? Also, The UIUC archive doesn't have a Squeak category. Is there a Squeak archive anywhere? That is to say, Smaltalk code that works under squeak, not implementations of Squeak, which are widely availiable/accessable. -- Mike Klein
