Hi we are giving some skype lectures to cameron students with damien. A fun experience, because the network is so bad that I cannot demo Pharo interactively. But I'm learning from it. Stef

Status of Twitter (api/analysis/visualization) in Pharo?
by MartinW June 25, 2015

June 25, 2015

Hi, I want to do some interaction with the Twitter API (retrieve tweets based on hashtags mostly) and visualize results of some analyses using Roassal. I saw there are some projects on Smalltalkhub, but none has much/any/up-to-date documentation. What is the current status of these projects? Does anyone know about any up-to-date documentation or examples? I am thankful for all hints. Best regards, Martin. -- View this message in context: http://forum.world.st/Status-of-Twitter-api-analysis-visualization-in-Pharo… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

the importance of your story
by Tudor Girba June 25, 2015

June 25, 2015

Hi, I gave last week a talk at NDC Oslo on "Don't demo facts. Demo stories!". While the talk is less technical, I did exemplified the message by demoing Spotter in comparison with the search support from Eclipse. There are several things I would like to emphasize. I compared our solution with an "industry standard" one. We often think our system as being niche and perhaps not mature enough. We need to change that perception about our work. We build state of the art. One thing that I did not mention explicitly in the talk is the size of the implementation. The Spotter implementation is 3500 lines of code -- and that it is so large because it currently comes with its own widgets. Furthermore, the extensions average 8 lines per custom processor (including the method header and the pragma). This is orders of magnitude smaller than what is typically out there, and it is precisely the reason why we can compete even if we are fewer. But, to get out there and compete we have to set that high goal for ourselves. For example, with GT we do not want to compete. We want to outcompete. So can you. While details are important, high goals require us to get away from those details. Only polishing details will tend to limit you to incremental improvements. We need to jump from time to time. But, these jumps are hard. On the one hand, it is hard to find the right jump and convince people to jump with you. On the other hand, they are hard to predict. For example, Spotter would have not been predictable one year ago. Yet, dry goals are not enough to keep us going. We need stories that make us dream. And the beauty is that Pharo breaths such a story. We should not limit ourselves to that story only. For example, with GT we want to reinvent the developer experience by making the developer be able to mold visual tools to her context because that is the only effective way to build sustainable systems. This little point of view will turn the IDE upside down, and this is only possible in a system like Pharo. Choose your high goal and tell its story through the system that you build. And remember that Pharo already offers a beautiful story to start from. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Morphs automatic repositioning (and resizing)
by Mark Rizun June 25, 2015

June 25, 2015

Hello, everyone! Let's say I have morph which contains few other morphs. Is there any way to reposition all these submorphs (if needed resize, but it's optional), so that they do not intersect with each other? Thanks in advance, Mark -- View this message in context: http://forum.world.st/Morphs-automatic-repositioning-and-resizing-tp4834043… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Proposed fix for RFB. Please review
by Christer Assmundsson June 25, 2015

June 25, 2015

Hi all, I have fixed (?) an issue in RFB server that seems to solve a problem I had with initiating a session. After the fix it works at least with UltraVnc. Still not with tightVnc though, has to be some other problem with that. As I'm not very experienced with pharo I'd like to have somebody elses eyes on it before checking it in to SmaltalkHub (if I even have access to that). Quality status on the fix is "works on my machine" At the start of RFBSession>> sendFramebufferUpdate | updateRegion nRects sendCursor sendPosition | preferredEncoding ifNil: [^self]. "<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< new code" self beginUpdate. ... Reasoning: Until we know what encoding to use, we can't send updates. Just discard them. It will be picked up later. Technical: Futher down in the method we call "countRects" which is not set until we set encoding, and therefore the method fails with DNU. Please let me know how I should proceed. Best regards, Christer

Re: [Pharo-users] Moose

Hi Actually I am not using a specifc tool to generate feature models. For the moment, I am using XML Files to express features because tools like SPLOT use such format so it would be easy to export it into Moose. It would be nice to have the Frascati feature model file, just to test some new metrics and visualisations and better understand the code :) Abdelghani Â DeÂ : Alexandre Bergel <alexandre.bergel(a)me.com> ÃÂ : abdelghani ALIDRA <alidrandco(a)yahoo.fr> EnvoyÃ© le : Mercredi 24 juin 2015 17h03 ObjetÂ : Re: [Pharo-users] Moose Hi! No, we do not have a particular description of the text file. This was made in a very ad-hoc way, and very close to Familiar. Since I guess you are using your own platform to express features and variability, I guess this text description is not that useful for you.

Roasal: Putting a white background instead of a transparent one in word clouds
by Offray Vladimir Luna CÃ¡rdenas June 23, 2015

June 23, 2015

Hi, I have finally finished the first part of my visualization project of political discourses on Twitter. You can see the details here: http://mutabit.com/offray/static/blog/output/posts/visualizing-politiciansp… (As you can see Pharo was not used to extract the data, just to scrap it, structure it and visualize it). The politicians tag cloud look nice if the background is white, because the png background is transparent, but if you share it on Twitter, the black background makes the tag cloud invisible. I could use image editing programs to change the background from transparent to white, but I would like to know if there is a way to make that change inside Pharo/Roasal. Thanks for all your support in making this ideas possible. Cheers, Offray
