Re: [Pharo-project] A test crashes (win32) cogvm

by Igor Stasenko

yes.. i had similar crashes.. and always involving the progress bar(s). but i was unable to find a fully reproducible case. :( On 3 April 2012 16:31, Martin Dias <tinchodias(a)gmail.com> wrote: > Hi > > Almost 100% of the timesÂ (but not always)Â I run certain Fuel test, the vm > crashes.

[Pharo-project] SS3 downtime - today 2pm PDT

by Dale Henrichs

We are in the process of tracking down the root cause of inordinate i/o delays on http://ss3.gemstone.com[1]. In the meantime, we're going to tweak some of the system settings and will cycle the stone. The plan is to cycle the stone this afternoon at 2PM PDT and the system should be down for just a few minutes ... if that will cause any inconvenience let me know and I'll reschedule ...

[Pharo-project] Fuel and Pharo Kernel

by Pavel Krivanek

Hi, I tried the Fuel with Pharo Kernel and... it works well. It needs only very few modifications (removing of some dependencies). But the really great thing is that the FLPackageLoader seems to work quite well too. I do strongly recommend to add Fuel very early in the development of 1.5 into the basic kernel packages. I can not wait to see a Pharo image without the Compiler ;-) -- Pavel

Mariano, We are on shared hardware in the VMware data center and I've seen occasional high i/o delays that are not related to GemStone activity...we're looking into this...

You know, when I first saw that it is possible to 'copy' a version to different repos from the ui, i was thrilledâ¦ but it takes too much time to copy 10 versions to 3 repos. Gofer is better but not yet good in this regard ;) best -tobias

Re: [Pharo-project] HMI

by Ben Coman

I am an electrical engineer whose work includes SCADA programing for operator interfaces of industrial plants using Citect [1] and a bit of Wonderware [2]. Both of these products include very nice sample projects for their tutorials - which would provide a student a good introduction to the functionality required of a HMI development tool. What do you mean two-tier HMI? In my work, tier1 would be a PLC containing the running control model of the plant, providing measured values to the control logic programmed in the PLC and driving relays and actuators. Tier2 is the HMI that provides the mimic of the PLC as a graphical representation of the plant, colourizing warning and alarm conditions, fill levels of tanks and allowing the operator to send commands to the PLC to start machinery. Something doing this based in Smalltalk would be wonderful.

Server-side (Pharo) will simulate network components and their data, and provide relevant events for client (Amber). The latter will present network items, their state and associated information, and provide UI to control them. An important part of this system is a communication layer between Amber and Pharo. > > > Benefits for the Student > > > The student will gain experience in building client-server applications with advanced UI and providing two-way communication between client and server. > > > Benefits for the Community > > An ability to create highly interactive web-based applications is a must-have feature for any modern development system. Amber is a bleeding edge in this area in Smalltalk world. A good communication layer between Amber and (for example) Pharo is a very appealing decision for building complex client-server systems. > > > > > > Best regards, > Dennis Schetinin > Sent with Sparrow (http://www.sparrowmailapp.com/?sig) > > > On Monday, 2 April 2012 Ð³. at 21:47, Janko MivÅ¡ek wrote: > > >> Hi Dennis, >> >> I'd suggest to go ahead.
