Phaas - anyone interested in setting up Pharo as a Service?
by Andy Burnett Jan. 29, 2013

Jan. 29, 2013

We would love to develop more of our ideas in Pharo, but we are completely allergic to doing sys admin. We don't want to deal with anything below the Pharo application level. What I would ideally like to see if something like Heroku, or similar, but for Pharo. However, just wishing won't make it happen, so I am wondering if there is anyone out there who is thinking about this, and whether there are enough of us to constitute are market. Our requirements are pretty simple. We need a way of uploading an image, and some standard for of persistence. At this point, we would be perfectly happy to make compromises by agreeing that it had to be e.g. Mongo or whatever (although ideally it would be gemstone). We just want to make some progress on this. Personally, I think lots of bits are coming together. We now have various persistence options, websockets (both in Zinc and Aida-web), OAuth ( in both places again), and lots of other exciting elements. We just want a really simple way to take advantage of them. Does anyone else feel this need?

The way to get this stuff started is to first make sure you can automatically provision whole boxes. There is some work done for this for a gemstone-seaside box: there are chef scripts, mostly by Willem and Norbert https://github.com/noha/virtual-gemstone The place to talk about this is this weekend at FOSDEM. There are devrooms focusing on these issues: Configuration Systems Management (Puppet & Chef), Testing and Automation (the Jenkins guys) Virtualisation on saturday and Cloud on sunday I'm not sure at what market heroku and appfog are aiming. They don't seem to have the right incentives to perform well, as they make more money if you need more instances. Might be perfect for hosting marketing campaigns or so, but definitely not for freemium based business models. DevOps on Hetzner servers might be a lot cheaper. Stephan

petit parser
by Hilaire Fernandes Jan. 28, 2013

Jan. 28, 2013

Hello I try to extent the example of the arithmetic evaluator[1], I don't understand the magic underneath nor how you will make it works with substraction. Changing method add to: add ^ prod, ($+ asParser / $- asParser) trim, term to parse mixture addition and substraction is wrong: parser parse: '1 - 2 + 6' -> #(1 $- #(2 $+ 6)) The precedence is wrong. How will you make it work? It seems to me the way to handle precedence in the example is not suited for extension Thanks Hilaire [1] http://pharobooks.gforge.inria.fr/PharoByExampleTwo-Eng/latest/

>> . > > I built CloudFoundry so that you uploaded a .st file (in my ESUG example it was 'aida.st') that was used to build the image. The server executed the .st file and saved the resulting image (it could load .mcz files directly or execute a Metacello script). Whenever your application was needed, a copy of the saved image was used. > > James Foster James, can I check a few assumptions - I want to make sure I am not putting words in VMWare's mouth, or missing an opportunity. 1. Is it the case that CloudFoundry.com has no current plans to offer gemstone as a hosted option? 2. Your work on getting Aida to run was targeted at the cloudfoundry.org, And therefore it would require someone to set up a separate hosting operation - using the cloudfoundry code - in order for us to use your work? If 1 and 2 are true, is there anyway that we can use the .com side in pursuit of this PhaaS objective? I assume not, but I would hate to miss the simple fix :-) Cheers Andy

MenuMorph - dual column?
by Ben Coman Jan. 27, 2013

Jan. 27, 2013

I have a MenuMorph with too many items, such that it fills the screen top to bottom and there are still some not shown. Is there some inbuilt way to have the menu come up in two columns? I could otherwise work at manually segregating menuitems into submenus, but the menus are dynamically generated and I'd prefer multiple columns. cheers -ben

<<< I would prefer to upload a MetacelloConfiguration (or something similar) instead of an image. I like to think about the image as a temporary runtime. Not something where I store code or someting I deploy. I would love to have something like: $ pharo -v 1.4-summer myProject.ston where myProject.ston would contain all the necessary information to load my project (dependencies, repositories, etc). This command would create an image with my project on the fly from a stock Pharo 1.4-summer and launch it. It would recreate the image everytime I want to work on my project (or when it is deployed). The problem right now is the loading time for dependencies (try to load seaside in a pristine image, you'll get the point). All the other bricks are there.>>> Sounds like a very good idea. Does anything like that exist already? Also, it raises the question of what should be in the base image. Cheers Andy

Nautilus SBD IC buttons
by Francois Stephany Jan. 27, 2013

Jan. 27, 2013

Am I the only to never use the buttons on the right in Nautilus? In practice, when do you need to see the bytecode/decompiled versions of a method? Is there a way to trigger the Instance and class variables buttons with a keyboard shortcut? Is there a way to remove completely the panel containing those buttons? Cheers, Fa

I would like to suggest that anyone who is interested joins, and we can produce a first attempt at a plan - and maybe some running code :-). Anyone else interested?

> > you could use cloudfoundry for that :) > > http://www.cloudfoundry.org/ > > Esteban Yup, cloudfoundry could be great too. Particularly if it made it easier to get gemstone running. I think it is important that we try to reach a consensus on this, purely to minimise duplicated work. It would be great if - for example - the pharo consortium were able to issue a new cartridge when they issue a new pharo release. So that the hosted version of pharo is automatically kept up to date. My vision is that we end up with a one-click hosting model in just the same way we have one click pharo. That would be fantastic :-)
