[Ann] Calypso system browser

by Denis Kudriashov

Hi I am glad announce first initial version of new system browser called Calypso. It is implemented from scratch with idea to build model suitable for remote scenario. But as result it leads to more important goal: provide clean implementation of browser which people could understand and evolve. Calypso supports most features from Nautilus but also miss many of them. And there are many not nicely looking parts of UI which require more work. But in same time Calypso provides many new cool features with clean implementation underhood. I put many things from other smalltalks and old browsers which I always miss. I release Calypso in the state where I finish most design decisions which I think important for project evolution. Of course there are a lot of things to do and improve. But browser is fully working. And now it is important to community to participate in project and make browser great again :). We need escape from Nautilus pasta world. Please report any ideas/bugs on github page https://github.com/dionisiydk/Calypso/issues. I already fill it with my wishes. Next step I will work on documentation/class comments and I will publish couple of posts about Calypso internals. Read more details on my blog <http://dionisiydk.blogspot.fr/2016/12/calypso-new-system-browser-for-pharo.…>. It includes pictures, videos and loading script. Best regards, Denis

The user interface from the Epicea window already allows me to switch between current session and all sessions, and usually the decision of what to look at is based on whether I find what I am looking for or not.

Re: [Pharo-dev] Epicea user experience report

by Esteban Lorenzano

this is a debate we have with Stef time to time: my side: just descriptive names that explain them selves what they do. Stefâs side: cool fantasy names, that have some âpunchâ. After more than 2 years arguing... both arguments have pros and cons :) for example we can have several browsers then we need to identify them and just call them âclass browserâ is not enough. But of course, a newbie will have a hard time trying to figure out what âNautilusâ meansâ¦ (btwâ¦ the world many says "system browserâ and not âNautilusâ but then we have âmonticello browserâ and not âSCM package browserââ¦ and later we will have âIcebergâ and not âSCM project browserââ¦ so is not consistent either... also if everything is a browser then nothing is, etc., etc., etc. :) â¦ now, what I would like is a way to find tools both from his fantasy name and function (for example: âEpicea" and "change loggerâ)â¦ and a way to list those tools/components in both waysâ¦ Yeah, Iâm aware this approach âsolvesâ a problem by adopting both solutions instead proposing a synthesis, but wellâ¦ this is the better I was able to elaborate :) Any ideas are welcome, both on whatâs better and how to implement it.

Re: [Pharo-dev] Q: any work around ROS has been done on Pharo?

by Max Mattone

Hi Igor, I played with PhaROS quite a bit while I was working at Mines Douai. But at the time, cleanning instances was quite an issue.. I use to tend to work with rosMaster instances that already exists or build a new image everytime it get too slow because of those ros master instances... You can try: ''' PhaROSSystem cleanAll. ''' But I think it keeps some instances anyway. As far as I remember, I think they were working on rebuilding the networking interface to solve this issue. And Santi was also working on PhaROS2 looking for robustness... I dont know the statut of those projects. regards, maxmattone Le lun. 26 dÃ©c. 2016 Ã 00:09, Igor Stasenko <siguctua(a)gmail.com> a Ã©crit : > > Hmm okay, i created own ros package > and started an example nodelet that prints 'hello world' , when i push > messages from outside by ros.. > now the question is how i should gracefully stop these nodelets and let > them unsubscribe/die gracefully.. > because i now have 4 instances of ROSMaster in my image and all locked by > waiting for some mutex/semaphores and > telling them 'stop' waits forever and blocks everything.. > How i can clean this up? > > > > -- > Best regards, > Igor Stasenko. >
