binary serialization

by Robert Withers

Does Pharo have stream classes to binary de/serialize an object, such that the protocol accepts an object as an argument and converts it to a byteArray? -- thanks, Robert

Re: [Pharo-dev] Slack?

by Dimitris Chloupis

extremely, nothing comes remotely close. Pretty much every open source project has at least one channel in freenode.net, quakenet is very popular with gamers . #python has around 2000 people online at all times, #clojure 700 , #java 466 , #c++ 1000, #emacs 1000, there is even irc channels for computets back from the 80s like my first computer Amstrad CPC 6128 at #cpc etc Blender which the program I use the most has around 5 channels, Blender also is a bit special in that all the development effort is coordinated via irc meetings usually every Sunday where all main devs are required to attend , moderated by the project leader , and make decisions on how the project should proceed, which features should go in and when the releases should come out. The project leader then publishes the meeting notes on the website which is a summary of the irc chat. There are other projects that follow similar approach to their development too like mypaint and Gimp.

Re: [Pharo-dev] [Vm-dev] Re: issue with large file path on windows

by Thierry Goubier

Hi Eliot, I believe everytime this comes up, it is not an issue of filetree making files too long for the filesystem, it is an issue of Pharo not being able to read or write a valid file for the filesystem. It is easy to "fix" filetree to workaround bugs in FilePlugin on Windows, but I'm not sure it's the right way to solve the problem ;) Simply because someone will hit it when reading a random, valid file one day.

updated Cryptography

by Robert Withers

I am attaching the .mcz as I am unsure where to publish it. I fixed a few issues (hex is lowercase and inputs to SecureRandom) and all tests pass green in the latest Pharo 5.0. Is there a good place for this to live? -- thanks, Robert
