[ANN] CoViD-19 Charts prototype
by Christian Haider March 20, 2020

March 20, 2020

Hi all, the corona virus is a bummer and it keeps me occupied more than is good for me, I guess. Since I am unhappy with some infos on the web (some are really nice!), because I want to see different numbers and charts. So, I used the opportunity to try out Amber for real. Here it is: https://covidcrt.uber.space It is still bare and simple, but here I can get a better picture of the development of this crisis. Especially, I wanted to see how the case increases develops (how fast is the increase increasing). I look at Italy, Germany and especially, the US. This is scary! >From today until Sunday, there will be a virtual hackaton from the German government [1]. I want to participate and will work on this. Anybody interested? You can apply until 14 o'clock GMT. (And yes, I know that it is stupid that Germany does it on its own, but better than nothing!). Technicalities (for people who want to play with the source): Everything is open and under MIT licence. 1. There is a small VisualWorks program loading the data from the John-Hopkins-University, transforming them and saving the data as JSON. The package is [CoViD19] in the public store. 2. The app is in Amber Smalltalk and the html is done with Silk. Silk is very exciting and makes web programming fun again. I am completely enthusiastic about it :-) ! Unfortunately, setting up the development environment is a bit complicated, because I issued a pull request[2] for an addition to Silk which is not incorporated yet. Therefore, after you did all the normal setup, you need to replace the Silk source files in ./node_modules\@ambers\silk\src with the files in [3]. Also, I disabled my dev buttons in the app. To open Helios, the browser, you have to enter require('amber/helpers').popupHelios() in the browser console of the dev tools. Happy hacking and good luck to everybody, Christian [1] https://wirvsvirushackathon.org/ [2] https://lolg.it/herby/silk/pulls/11 [3] https://covidcrt.uber.space/Silk.zip

business partnership
by Stéphane Ducasse Feb. 13, 2020

Feb. 13, 2020

Hi all! This is not a job offer, but kind of: I'm looking for a business partnership with other Smalltalk developers (Pharo). The story: Since many years I have changed all my work and all my customers to Smalltalk. So I am working 98% percent on Smalltalk, having a few projects in Switzerland. Three big projects will be open sourced soon in the next weeks. For some customers - who are using these projects in their business - it is vital to have another developer besides myself. The 3 open source projects are all Seaside based web applications: a school management software (Gymnasium), a media assets application (targeted for schools) and an e-learning platform (for learning languages). All three applications are already used in production. The goal: I am looking for standalone Pharo developers or companies who would like to build a partnership particular around these open source projects and in general. Currently I am offering a project for a new customer. Knowledge of the German language and nearness to Switzerland is very beneficial, since the applications do have a german UI and the customers do not speak Smalltalk :wink: If you are interested in a longterm partnership of this kind, please contact me via andreas.brodbeck(a)mindclue.ch. Cheers!

Pharo4pharo mailing-list announce
by Stéphane Ducasse Jan. 30, 2020

Jan. 30, 2020

Hi Tired of boring and dull discussions about the past? Tired and bored about the fact that the discussions are not about Pharo but about X, Z, K? Want to get in touch with other real pharo users? Want to have positive and nice discussions about Pharo? This mailing-list is for you https://lists.gforge.inria.fr/mailman/listinfo/lse-pharo4pharo I created a new mailing-list for Pharo 4 Pharo. The idea of this new mailing-list is to exchange between Pharo users on Pharo. If you want to talk about the weather and other cool fishing practices or how other languages are super cool, then you should use another mailing-list. You can consider that I’m [ ] an asshole [ ] an arrogant idiot [ ] other This is not my concern. My concern is: can we respect Pharo and users of Pharo that want to share what they are doing and ask questions about their language? If you join this mailing-list be warned that I (yes me the benevolent dictator of Pharo) will remove you from the mailing-list when you get on my nerves. If you do not like it, do not like me, do not appreciate it, do not join! S. BTW they are plenty of newsgroups about Smalltalk and you can join there. -------------------------------------------- Stéphane Ducasse http://stephane.ducasse.free.fr / http://www.pharo.org 03 59 35 87 52 Assistant: Julie Jonas FAX 03 59 57 78 50 TEL 03 59 35 86 16 S.

Fwd: [Pharo-dev] Characterizing Pharo Code: A Technical Report
