Re: [Pharo-users] help bij one of the last challenges of the chapterof network simulation of the oop book.

by Richard O'Keefe

We don't know what you are actually trying to do. WHICH book has the problem you are trying to solve? I spent some time looking at the code in your repository, and the KA* classes look very "passive". I don't really see any simulation going on anywhere but in the test cases, and that just feels wrong. I would expect a network simulator to model network nodes as Processes with SharedQueues of messages coming in and responding by sending messages through other SharedQueues.

Re: [Pharo-users] [ANN] XMLWriter moved to GitHub

by Torsten Bergmann

Hi Cyril, > This is really cool thanks! I just step in - looks like people where too shy so far. > Do you plan to also migrate XMLParserHTML and XPath? Yes - more is in the pipe already. You can follow activities on GH. > Also, I have a question. Why the "XML" prefix? I find it redundant > since there is already XML in the name. "pharo-contributions" is having also non-XML related repos. So this is a kind of simplistic repo-grouping for all XML related repos. For XMLWriter it is redundant - but I plan for XML-XMLWriter XML-XMLParser XML-XPath XML-Pastell XML-... so when you filter contribution repos in github for "xml" you will easier find or recognize it. Same in Iceberg when loaded. Hope this makes sense to you as well ... Bye T.

Status of Encryption / Keys / Etc

by Eric Gade

Hi all, I'm try to get an idea of the status of keys and key signing (cross platform if possible) in Pharo. Do we have general mechanisms for signing pieces of data, and for encrypting/decrypting based on public/private key pairs, including those set as the default for a given user on a given system? Thanks. -- Eric

Html5 inputs examples for seaside

by Oswall Verny Arguedas C.

I would like to know if you have examples of use for html5 inputs in Seaside 3.3. I am with the Seaside book on the website. I have examples of textInput and others, however I am interested in inputs of numbers, dates, months, html5 colors, apply calculations and get results. I have errors in syntax. I need to establish memory variables that should not persist and then perform calculations on methods and only totals persist. Thanks in advance. Oswall
