Re: Squeak logo-wear?
by Jan Theodore Galkowski 27 Oct '99

27 Oct '99

I want a few, for two adults and two kids (11 and 13). Among other reasons, I'd love to wear them to DisneyWorld during our Millenium trip next summer. --- ________________________________________________ Jan Theodore Galkowski demiourgos(a)smalltalk.org home.stny.rr.com/algebraist/ squeak.org/ www.smalltalk.org/ On Fri, 15 Oct 1999 18:06:12 Tim Rowledge wrote: >If I get time before OOPSLA I hope to get a sweatshirt and some badges run up >with the Squeak logo on.

Re: Why 'primitiveShutdownNetwork absent?

Hi, > If there's a real need for a shutdownNetwork primitive, I'd > be happy to include it and just have it be a noop on the Mac. > But is it really needed? The short answer is "yes". read the following written in my bad English if you want to know why. (somehow, I really lost the confidence in my skill of english, sigh.) ... I think I wrongly mixed two different things. The network shutdown and the PPP connection. There is the declaration for sqNetworkShutdown() exist in "sq.h". I think the porter is supposed to define the function to be "symmetric" to the sqNetworkInit(). On Windows, as far as I know, the network is automatically initialized by OS when the network API is called first time. The network is alive until the user select the "disconnect" button. On some UNIX, the user might have to invoke "ppp" command or something to start the network session if the machine is not directly connected to the network. Anyway, the network support code doesn't do anything about the network session. In either case, the symmetricity of the network support code seems kept. On ZaurusOS, the sqNetworkInit() have to call the network init API explicitly. Likewise, the application have to call the network shutdown API. In fact, there is no other way to shutdown the network session. Of course, I wrote the sqNetworkShutdown() to be called from ioExit(), but it is still better to have a way to call sqNetWorkShutdown() manually. > a. It's not entirely clear when you'd want to use this primitive, > since some other Squeak process might still be using the > network. Yes, but the same thing can be applied to the other primitive, such as the change of display depth and extent. If the user is sure to shutdown the network, I think the user should be able to. # I could put an OS-native button on the screen for it and # don't modify current Squeak, but I think it is not clean. > In contrast, primitiveInitializeNetwork is > implemented in a way that it does nothing if the network has > already been initialized, so every piece of code that uses > the network can safely begin by calling primitiveInitializeNetwork.

(In more sensible OS's with memory protection, of course, > this wouldn't happen.) As I wrote above, I just put the call to sqNetworkShutdown() in ioExit(). But I'm not so sure what is going to happen when ZaurusOS crashes. ... The situation of Mac seems somewhat special. Is it because the applications share the same address space with OS? I thought the user is supposed to reboot Mac when the VM crashes:-) Thank you. OHSHIMA Yoshiki Dept. of Mathematical and Computing Sciences Tokyo Institute of Technology

Oh, my lord, I'd _kill_ for someone who would actually _teach_ me how to do this in ST... Ain't gonna happen I know, but man that is the one thing I wish I could show people. Even speech means _NOTHING_ to most people. If they aren't quadriplegics and have nada else, then they will be there the same as ever. That is ST's real hurdle.

Why 'primitiveShutdownNetwork absent?
by ohshima＠is.titech.ac.jp 27 Oct '99

27 Oct '99

Hi, I'm about to finish writing the network support code for a PDA. I was a bit surprised When I found there is no primitive assigned for terminating the network session. Is it OK to assign primitive 226 for 'primitiveShutdownNetwork' and implement it in the similar way to primitiveInitializeNetwork? I wonder how people shutdown the PPP session. They just do it by using the host OS' function, or they just don't do that because they use fixed charge telephone?

telemorphic
by Stefan Rieken 27 Oct '99

27 Oct '99

Hello, There's still little info on telemorphic. Can anybody tell me how I should setup a telemorphic session? I got as far as connecting a remote user (simply "help -> telemorphic -> connect remote user"), but I can't get the user to get in contact. If anybody can tell me, I shall add his info on the Swiki. (Yes, I feel guilty about only asking questions here but never providing answers ;-) Greets, Stefan

John, I recommend a careful look at the extensive work done for Eiffel's memory reclamation and the issues involved, in <a href="http://www.eiffel.com/doc/oosc/page.html">OOSC-2</a>, about pages 304-314. Also, we're fortunate that a lot of this stuff <a href="http://www.eiffel.com/doc/manuals/technology/internal/gc/page.html">is online</a>, too.

I don't disagree with any of these sentiments, I think this is all great stuff. But as the token lawyer among us, I need to say the seriously unfun thing: Do we have the rights to those fonts? Under the Squeak license, certain Apple-owned fonts were within the scope of the license -- are these they? Are the new strikefonts unauthorized derivative works? I haven't done the download yet, but someone should check the licenses. It may be possible that each individual who has an Apple or Microsoft OS may be licensed to use certain fonts provided with those systems, but that we as a community may not be authorized to distribute same to non-licensees. Perhaps the simple expedient of finding the (C) owner and trying to get permission to use the fonts with the product? (OR focus instead on providing mechaisms to automate building of these fonts from existings fonts (which the person running the program is presumed to own a license to use if he has it)) At any rate, good work.
