Cloud Hosting why/when?

by Stephan Eggermont

When I see the enthousiast reactions to the cloud hosting tip, I often wonder why? What do you see as the advantages, and where does it provide a good fit? I can understand the 5 euro/month vps for a single instance case. As soon as I need redundancy, monitoring and scaling, I still need to understand so much of the underlying infrastructure that the step to DevOps seems awfully small. Neiher Heroku, nor AWS make scaling transparent, AFAIK. That is to say, they'll start up new instances just fine. That only helps when processing is the problem, not internal bandwidth. And solving the wrong problem only leads to high costs. The cost figures I've seen published on the web suggest that most larger scale usage would be better of with at least their regular demand covered by dedicated servers. I know hosting in the US is much more expensive than in Europe. Digitalocean at least seems to give more reasonable price/performance. AWS vs Hetzner seems uncomparable Your thoughts? Stephan

As far as I saw, the Tabs are not going through the theme to decide the look and feel. Could we work on this? Perhaps we can take the opportunity to try a new oo-design for the theme code: I proposed to have a theme strategy per morph and have the theme be a conglomerate of these strategies.

[ANN] Eclipse icon pack for Pharo 3.0

by Esteban Lorenzano

Hi, I want to share something I made experimenting with different enhancements for the look & feel for Pharo. The general idea is to create an environment who can be both modern and more appealing to newcomers, and as part of that I played with and "Eclipse Pack" , to make the environment a bit more familiar to outsiders :) you can install the icon pack executing: Gofer it smalltalkhubUser: 'estebanlm' project: 'EclipsePack'; package: 'EclipsePack'; load. ThemeIcons current: EclipseUIThemeIcons new. World resetWorldMenu. NautilusUI resetIconCaches. Then you can have something that looks more or less like this: or if you install the Glamour theme (which I like a lot more :), something like this: and... before all who hates java complains: no, this icons will not be included in the distribution... is just a candy (even if I use them everyday)... we need our own icons, not famfam, not eclipse... just pharo icons :) Enjoy, Esteban
