Its a shame nog being able to read the article, because it is not posted in the open web and I don't have Facebook or Google to pay with my privacy for the "privilege" of reading Fast Company. Anyway, I agree with Hilaire. It's pretty difficult to be between worlds trying to bridge education and informatics (or activisms) when one part is extremely focused in their own extreme of the bridge and the stuff at the other side is so alien.

You should also post your requirements on the GLASS list (http://forum.world.st/GLASS-f1460844.html) A number of people/businesses there use a /develop on Pharo, deploy on GemStone approach/. They will be able to give you some good advice on using GemStone/S for your database. > We need a web stack and we put Pharo & co in the comparative process. > My team have strong experience in load-balanced php / mysql deployment > that handles millions of records but we are ready to build on > something else though MySQL is still a requirement. > > Thanks for Garage + Glorp, I can prototype things.

Re: [Pharo-users] Continued Fractions

by phil＠highoctane.be

I need to match print ads sizes from various publications with a standardized list of ratios (e.g. 2:1, 1:1, 2:7...) plus a bunch of other metrics. So a rect of 1543@331 gives a float value that has can be best approximated by a continued fraction approach. But there are other complications. Now I am using a lookup table and try to match with just a distance. I am using DataFrame and hopefully more Roassal for all of this. Pharo can be a good tool to manage the object model of this problem space. I am prototyping something. We'll see how far I can get.

Re: [Pharo-users] Smalltalk gets a reference in fastcompany Kay interview

by Hilaire

Thanks to share the article. Alan Kay thought can be hard to follow, especially considering, in one hand, his main foci are education, educating, authoring media, and in the other hand, his audience is mainly in the computer field without much notion about education & al. His main vision, about computerized authoring tool to enlighten the mind is a strong and exciting assertion. In this vision, the users will build their own model to explore a given concept. Etoys was really what came close to this idea, with medias you can interconnect to build simulation, model, etc. It let you build these things more easily than any programming tool. However I am wondering if even talented young students or teachers can really embrace it. I know talented teachers and I doubt they could do it with Etoys. May be Etoys was just itching the surface of this vision.

Hi laurent Let us know how we can help. If necessary we can send our 15 year experience Java Architect and nearly the same in Pharo (Esteban) to meet you at Annecy. Did you see that Sven released also a native driver for SQL30? I do not remember. I do not know if you see but sorabito deploys everything in Pharo and they mixed also mustache and Seaside. BTW I know a german company that got a nice and large project for a large train company and they will use Pharo on the server (plus mobile apps and others). I can put you in contact also. Mariano and Quuve used Gemstone + magritte. But this is not the same techno :) Stef On Mon, Sep 18, 2017 at 12:22 PM, laurent <laurent.laffont(a)gmail.com> wrote: > Hi all, > > it's been a long time :) At work we are currently comparing several > technologies to start a business project that will hopefully be used by > thousands of people for several years ;) > > We need a web stack and we put Pharo & co in the comparative process.
