[ANN] ReStore for Pharo - object<>relational database framework

by John Aspinall

Hello, At ESUG 2018 I gave a presentation on some aspects of ReStore, my object<>relational database framework for Dolphin Smalltalk. Afterwards a number of people asked if ReStore was available for Pharo, the answer at the time unfortunately being âno". A year later I found myself with some spare time and decided to look at porting ReStore to Pharo (mainly to give myself some experience with Pharo). Iâm pleased to say ReStore is now available for Pharo and can be found at my GitHub account: https://github.com/rko281/ReStoreForPharo <https://github.com/rko281/ReStoreForPharo> Initially ReStore supports SQLite via UDBC and PostgreSQL via P3; kudos and thanks to the authors of these packages. Documentation largely remains on the âto doâ list but the ReadMe gives a flavour of what ReStore is and what it can do via a few simple examples. Please feel free to post any questions here and Iâll do my best to answer them. I hope some of you find ReStore useful! John Aspinall

Re: [Pharo-users] Calypso loading code spinner

by tbrunz

Hi Esteban, This sounds like your host OS is powering down your laptop's HDD while on battery, to save energy. Plugging it in triggers a different rule that selects "performance" over "energy savings" and keeps the drive up & spinning constantly. I would check the Win10 power management rules to verify this. You can also select a different power profile when on battery there, or create a new one (such as "power savings except for the hard drive" when on battery). -Ted -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Calypso loading code spinner

by Esteban Maringolo

Answering myself... It seems to be related with the power management because as soon as I plugged in my laptop the spinning effect went away (and also the whole environment got faster). Maybe it has to do with the guest OS power management, although I didn't see any noticeable slowdown in other apps within the VM. Is there any specific PM thing in the Pharo VM? Or should I look at the VBOX/Ubuntu settings. Regards. Esteban A.

Calypso loading code spinner

by Esteban Maringolo

It is happening to me very often that to access the source of a method, or sometimes to find senders/implementors, the Calypso browser takes a long time to load it. By long I mean from two to five seconds, sometimes longer. I'm running Pharo 7 within a VirtualBox VM with Ubuntu 16.04 in a Windows 10 host. Regards, Pharo 7.0.3 Build information: Pharo-7.0.3+build.164.sha.591a635c8922e5f1cff1d0b3fbf2e525b590d25f (64 Bit) Esteban A. Maringolo

Roassal 2 Stable: Problem browsing the source code of the examples

by Offray Vladimir Luna CÃ¡rdenas

Hi, We were at our usual data activism workshop, trying to visualize a tag cloud some Tweets about the civic strike in Colombia. Is happening all over Latin America, France, Hong Kong..., So would be nice to have a broad overview over the noise created by social media. Anyway, we installed the stable version of Roassal 2 over Pharo 7 and when trying to browse the source code of any example in the example browser we got the following error message when clicking on the Playground tab (nearby to the canvas): Instance of RBSequenceNode did not understand #formattedCodeWithMaxLineLength: This was a good opportunity to show other ways to approach to the code, but I think is important to improve a smoother experience for newcomers, including the ability to go from canvas to the source code in Roassal examples browser. Any clue about what is happening to the Roassal 2 Examples Browser? Thanks, Offray

Re: [Pharo-users] thesis on using ML for Pharo code completion

by HernÃ¡n Morales Durand

Hi Myroslava, I read your post (actually a few of them) and I have some questions: - I was surprised to read about n-gram model because at least in NLP was outperformed by modern DL approaches. But then I read you considered RNN (and maybe attention model?) so it sounds really interesting. - Do you plan to benchmark agains TabNine? I know they are a black box, but they seem to support Smalltalk https://github.com/zxqfl/TabNine/blob/master/languages.yml - ERNIE 2.0 supports continual learning (AFAIK this was only applied to NLP) so develop something which learns incrementally would be an option for your PhD? One problem, for me, of code prediction is gathering enough context information to make informed predictions (I ignore if there is something like GLUE benchmarks for code). This means to propose contextualized completions based on multiple factors: for example the class where I am positioned in the Browser, the recent used/written methods, etc. Of course the possibilities are infinite! Just thinking out loud.
