Re: [Pharo-users] Roassal Performance Issues when applying layout

thatâs most probably a bug in new FFI-NB backend. I would love some help here :) In any case, I will get back to FFI-NB as soon as I finish migration.

Rocket Chat - An open source alternative to Slack

by Dimitris Chloupis

So since Slack has been so successful for our community , far more that IRC has been in terms of participation and useful discussions (at least the 2 years I have been around) it made me wonder if I could find an open source alternative to Slack that is at least as good as it if not better without a very different workflow (so we have to learn everything from zero) all the big pros and something that could easily interface with Pharo. Ladies and gentlemen meet Rocket Chat https://rocket.chat/ The good news about Rocket chat is that it seems to have all the pros of Slack like close integration with tweeter, github etc etc . It has clients for all OS and mobile devices. But not the big cons like the 10.000 messages limit ( which we have long exceeded). Its open source and most importantly written in javascript and we know that pharo can interface with javascript in many diffirent ways . Hosted on Github and deployable with open source technologies. And even its license is MIT. The reviews I have read about it are very positive. So what do you think ?

Re: [Pharo-users] get json data from external url

When putting non-ASCII in URLs it is best (needed) to construct the URL manually from components. ZnClient new url: (ZnUrl new scheme: #http; host: 'maps.googleapis.com'; addPathSegments: #(maps api geocode json); queryAt: #address put: 'Flughafen SchÃ¶nefeld, 12521 SchÃ¶nefeld, Germany'; queryAt: #sensor put: false; yourself); contentReader: [ :entity | NeoJSONReader fromString: entity contents ]; get.
