Re: [Pharo-users] [COTDC] 89 - NullStream

by StÃ©phane Ducasse

I'm a stream doing nothing (NullObject pattern). I can be handy when a stream is needed and that we need to do nothing (for example a logging in off mode).

Hi Steph, It could be nice to have something between the Individual Member and the company first level support. Something like 'Freelance' for 1000â¬ maybe ?

Luckily, it's probably not going to be Stef taking care of the finance details :) Indeed I was thinking about the about the other range.

I have to see if works. *If not, I have no time to tweak it. *That would have the spring of 2009 (or maybe 2008!), and Pharo has definitely evolved since then. My smalltalk code at that time was probably very suboptimal -- so i too have definitely evolved since then. Nothing fancy: 2d display with little symbols (squares) of various colors, which would update according to state changes in the DB, and then you could right click and use a menu option to invoke a state change. And for the prototype, the db was simply an in-memory model. So I think i set up threads that would automatically change states of the devices, etc., so that it looked like a real world app. Report precsise bugs, > Send emails like that one, > sign the license agreement > are some ways to contribute :) > Great.

Priorities for me: easy GUI building, simple PDF generation, simple DB connectivity, and continued cross-platform portability... including mobile one day! Cheers, Cam

Re: [Pharo-users] Network save and load

by Janko MivÅ¡ek

WebDAV has additional advantage that is supported in many desktop apps like MS Office and LibreOffice. It essentially enables you to "save to the web" directly. For instance you can open an attachment in Aida/Scribo, edit it and save directly back to that attachment. No need to save localy, delete old attachment and attach back new one.

What I described should be WebDAV compatible (more or less, I haven't tried). >From where I stand, learning & configuring Apache and friends is a lot more complex and less fun than doing it in Smalltalk. But it also depends on what you want: as I said you have to consider account management, security and probably sharing. Sven

Well, aside from being a bit complex, ftp is also quite dated, and question is how many users would like to save to ftp or have ftp accounts. Maybe then WebDAV, it can be served by most web servers?

Thanks very much for your tips and examples, it is very valuable. Thanks a lot. On the server side I want to be server neutral, and use what ever resource is there: Apache, FTP.
