Support for UNC filereferences?
by Stephan Eggermont Dec. 20, 2015

Dec. 20, 2015

Perhaps we should add a UNC class? From slack: Ilshad Khabibullin [14:05] Hi there! Are UNC `\\server-name\shared-folder-name` in Windows not supposed to be working with FileReference? Ilshad Khabibullin [14:22] looks like it works in VW, for example. I wonder if we can use `\\WIN-SO4HTUV4HAL\TestShared\newfile.txt' asFileReference ensureCreateFile` but it doesnât work. It creates reference `File @ \WIN-SO4HTUV4HAL\TestShared\newfile.txt` instead of proper one. Have anyone advice how to manage working UNC? Ilshad Khabibullin [14:36] @maxleske: I think it should create FileReference to this shared (via network) folder. Max Leske [14:37] (BTW: UNC is implemented in the FilePlugin of the VM) Ilshad Khabibullin [14:37] but it creates, I think, FileReference to âC:\WINâ¦..` by default, it gets âC:\| Max Leske [14:38] So has the file not been created on the share? Ilshad Khabibullin [14:38] @maxleske: wow thank you! trying.. â[14:38] ah.. itâs already.. Stephan Eggermont [14:38] asFileReference on String might not do the right thing â[14:41] @maxleske: what do you mean by FilePlugin? Does it mean that Windows distribution of Pharo 4 has it? Max Leske [14:43] The virtual machine has it. You shouldnât need to worry about it. UNC is provided transparently by the C implementation. You wonât find any references to UNC in the Smalltalk code Stephan Eggermont [14:43] String asFileReference is ^ FileSystem disk referenceTo: self Ilshad Khabibullin [14:44] so it is supposed to be working anyway Ilshad Khabibullin [15:52] played with ZnUrl and finally managed it: `'file://WIN-SO4HTUV4HAL/c:/TestShared' asUrl asFileReference children.` it works!!

[ANN] Pharo Consortium Sponsored Development Effort
by Mariano Martinez Peck Dec. 20, 2015

Dec. 20, 2015

Dear all, I am tremendously happy to announce you that Pharo Consortium will sponsor yet another development effort. In this particular case, it's my honor to carry on such an effort and I will be developing and improving a few things and ideas. All the contract and paperwork has already been done so it's time to start working. Regarding the developments itself, we discussed about these topics: 1) Experiment with a simpler yet more limited OSProcess alternative to execute OS commands. 2) Improving FileSystem in order to better deal with some POSIX stuff like symbolic links, unix file permissions, etc etc. I have already started with 1). OSProcess is super complete and it involves some packages (OSProcess / CommandShell) as well as some VM plugins (OSProcessPlugin, AIOPlugin). OSProcess provides lots of features (like forking the running image) but we would like to focus only in executing OS commands. In addition, OSProcess dates from quite some years ago when many of the current infrastructure features did not exist yet. So the idea is to think a simpler alternative to execute OS commands, using new features such as threaded FFI (for example, for reading async from pipes), pinned objects, etc. We want to use FFI as much as possible rather than VM plugins. >From the image side, we are thinking about an API which would look like a builder-like API (FileSystem, XStream, etc). We have been discussing with David Lewis (OSProcess author) as well as with Eliot Miranda, Esteban Lorenzano, Damien Pollet, Stephane Ducasse, etc in order to agree in a project that would be worth doing (otherwise we would continue using existing tools). And they have all been very kind with me providing positive discussions. I will soon do a survey to measure the most common use cases of OSProcess and related tools. If you have any thought, question, feedback, or whatever, please let us know. Finally, note that I will be doing this project together with another client's project (Quuve) and my life does not have much free time these days...so please be patient!!! Best, -- Mariano http://marianopeck.wordpress.com

Pharo Pholks, Is the spirit of #GivingTuesday, I am publishing my secure session code in progress. Some changes to pharo's internals will allow this there, though I am currently doing my work in Squeak.

What Strides In Pharo?
by horrido Dec. 18, 2015

Dec. 18, 2015

Perhaps one of you can respond to this guy *at Reddit*. I'm not up with all the Pharo developments. He has used Pharo and he seems to be most displeased with it... https://www.reddit.com/r/programming/comments/3wv7ik/who_uses_smalltalk/cy2… <https://www.reddit.com/r/programming/comments/3wv7ik/who_uses_smalltalk/cy2…> "What strides? How about you write an article explaining that? I've used Pharo extensively and the biggest language-level change that has come about is slots. That's hardly a huge revolutionary change (it's also an exceptionally complex model for what it is!). The point releases of Python or Ruby, see bigger changes than this! [0] Now the Pharo guys have done a fantastic job cleaning up the image. But there's a long long way to go there, and there's the tiny fact that no available Smalltalk system bootstraps! Until that happens, and Smalltalk has a reasonable deployment model (writing scripts to strip objects from the image and crossing your fingers doesn't count!), it's hard to take even this clean up effort seriously. [0] The biggest changes in Smalltalk since Smalltalk 80 have been syntax for dynamic arrays, which nobody uses, because it's non-standard; Traits, which nobody uses, because it's non-standard, and the vendor specific syntax for dealing with packages. You can keep saying it until you're blue in the face but in comparison to just about every other language, these are not major changes! This is no "modernizing." -- View this message in context: http://forum.world.st/What-Strides-In-Pharo-tp4867485.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

New version (47) of SecureSession for Pharo & Squeak
by Robert Withers Dec. 18, 2015

Dec. 18, 2015

Please load the SecureSession.47 and drive it about a bit. I am missing crypto plugins on Pharo, so avoid the performance test, tto stay responsive. Here are some of the changes: - frame-based pipeline - header per msg so no mutable session state - header is written with message in Asn1Der encoding. - most header fields currently optional - adding per-connection msgId to header - timeSent set also - reworked TransportEndpoint to be better scoped. Looking forward: - extend frames into the strategy utilities - events Any issues or questions, please reach out. Thanks, robert

Rocket Chat - An open source alternative to Slack
by Dimitris Chloupis Dec. 17, 2015

Dec. 17, 2015

So since Slack has been so successful for our community , far more that IRC has been in terms of participation and useful discussions (at least the 2 years I have been around) it made me wonder if I could find an open source alternative to Slack that is at least as good as it if not better without a very different workflow (so we have to learn everything from zero) all the big pros and something that could easily interface with Pharo. Ladies and gentlemen meet Rocket Chat https://rocket.chat/ The good news about Rocket chat is that it seems to have all the pros of Slack like close integration with tweeter, github etc etc . It has clients for all OS and mobile devices. But not the big cons like the 10.000 messages limit ( which we have long exceeded). Its open source and most importantly written in javascript and we know that pharo can interface with javascript in many diffirent ways . Hosted on Github and deployable with open source technologies. And even its license is MIT. The reviews I have read about it are very positive. So what do you think ?
