pharo vm + plugins
by Robert Withers Dec. 19, 2015

Dec. 19, 2015

What is the link to help me build a 32-bit spur 50 VM? I want to build the crypto plugins. I have been having trouble with ubuntu building but I think CMake worked for me before. I will try, but I could loose the ability to even run the normal vm. sigh. Otherwise, I am really looking for the crypto plugins that are external for Ubuntu 32-bit. If you have generated these plugins, please email them to me, straightwawy, sos I can benefit from them and run the performance test to work on optimizing the FEC code. manythanks, -- . .. .. ^,^ robert

picking up a little speed
by Robert Withers Dec. 19, 2015

I was looking at Zinc to see how it works. My SecureSession was built without my knowing about all of Zinc and it looks delicious on the control side. Here is my latest stats: 100 KB data chunks received: 22 send time: 54 ms, rate: 325.926 Mbs. receive time: 143 ms. rate: 123.077 Mbs. -- . .. .. ^,^ robert

TCP server for Pharo?
by Denis Kudriashov Dec. 18, 2015

Dec. 18, 2015

Hi. I need simple TCP server which process incoming connection in separate processes. I see Zinc ZnServer subclasses implement something like that. But I'm not sure that it is good idea to reuse it. Zinc server has http related methods which I'm not need. What you think? (I don't want to implement another one incoming connections loop)

Serious issue with OSProcess on Mac
by Alexandre Bergel Dec. 18, 2015

Dec. 18, 2015

Hi! On my mac, using Spur, the following expression: (PipeableOSProcess command: 'ls /tmp') output return an empty string. This breaks completely the Git integration :-( Thierry has asked for credential to commit in the vm source code, but he is still waiting for a reply.

Re: [Pharo-dev] potential to include cryptography in base image
by Sven Van Caekenberghe Dec. 18, 2015

Dec. 18, 2015

Robert, I think that the Pharo community, part of which is more business oriented, is absolutely interested in more and better Crypto code. In any case, I am. What we absolutely want, if it is not already the case (I did not check), is that the Crypto code can be loaded using 1 single action (through our validated Monticello configurations and Catalog mechanism) - I am sure you will find help to achieve and maintain (through a CI process) that goal. Whether it should be a base part of the image is another question. Modularity is a huge goal for Pharo. This is a much harder discussion (as the same can be said of or asked for for many packages that are generally useful: XML, CSV, JSON, SQL, ...). In any the case, the first step is the one described in the previous paragraph. Then you need traction, usage, and maybe demand for full inclusion.

OT: Convince me github is a wise choice

Hi Ben, Hi All, I'm quite conservative when it comes to relying on others' infrastructure so I need some help making me take the plunge.

Specifically what is there to prevent some third party from buying github, or of github going public and the board taking the decision, or github on its own, deciding to charge for hosting, keeping the data hostage to extract payment? What safeguards are in place to prevent this? I'm not interested in "this will never happen" arguments. I'm interested in hard data please. [4] Provides pragmatic advice for cutting over.

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

Bugs I found during the lectures in Yaounde
by stepharo Dec. 17, 2015

Dec. 17, 2015

Hi today and yesterday I'm giving 6 hours of pharo lecture to 100 students and we have fun. Here are the bugs I found (I'm working on the latest 50) - we cannot bring menu in certain part of the debugger (may inspector) - class definitions are not logged in changes - when we write self shoulnt: [Dice new faces: 20 ] raise: Error the debugger does not show the create menu for the method faces: It would be good to record this. I have a reeeeeeallllly slow internet connection and only from time to time. Stef
