That's the reason why I was primarily exploring statically-compiled languages. Julia *might* be interesting since it is higher-level language with fantastic, close to C performance when one helps compiler by annotating data types. In short, I want to avoid fiddling with low-level languages, otherwise it would be simple to just use C/GTK or C++/Qt. (Java could probably also do the job, but I simply do not like it.) For the most critical part of the application, I anyway plan to use 3rd party C lib which does calculate planetary ephemeris, but for the custom libs using it, I want to use higher-level and type-safer language. > In any case there are always 3 rules, profile, profile and profile. > When it comes to performance assume nothing.

Right, it's just that Julia provides more 'traditional' dev work-flow, while with Pharo one has to unwrap one's head a bit. :-) > GUI wise you can do some pretty awesome stuff with morphic.Â That I still have to learn...

there is an an SQlite wrapper for pharo http://forum.world.st/ANN-Updated-SQLite3-wrapper-project-based-on-NB-td479… the screenshot you shared as Tudor said can be accomplished via Roassal and Morphic. Personally I find the whole performance question kinda irrelevant because if you really want to squeeze the most performance code those parts in C and call them from Pharo via its FFI. Not even Julia will able to outperform that since itself relies on C code for performance and its quite restrictive how you use its dynamic types to achieve high performance. In any case there are always 3 rules, profile, profile and profile. When it comes to performance assume nothing. In the vast majority of cases Pharo JIT VM should be more than enough. And if all you want to do is a business app I dont even know why you worry about performance. Business apps they are very low demand on performance. Pharo libraries dont get irrelevant because the language is so simple it barely changes and the changes usually dont brake compatibility. The only that broke AFAIK is the image format with the new Spur VM but that should not affect libraries. Pharo can do REPL via the playground, the whole deal is that is a lot more than that. GUI wise you can do some pretty awesome stuff with morphic.

Lawsuit Tracker app

by SaÅ¡a JaniÅ¡ka

Hello, I'm looking how to build GUI app with Pharo and today found out screenshot of Lawsuit Tracker (http://smallworks.eu/web/projects/lawsuit Tracker) which very much resembles 'typical' desktop/business application. The web site says: "It is made using Pharo, Glamour, Magritte and MongoDB." and in my case I'd replace MongoDB with Sqlite3, have need for more grpahical output - something like: http://saravali.de/screenshots.html but wonder about other components and whether they (Glamour/Magritte) are still relevant *today* ? Otoh, today I was re-reading some stuff about Julia language which looks as fine langauge, but it does not fit on one psotcard, although it provides more "classical" way of developing: editor+REPL along with Gtk(.jl) bindings. The language does perform very well, iow. it's quite fast which is good for my project, but it's a bit cumbersome since there is no support to compile end application, while it looks that Pharo has advantage here providing smoother way of deployment (multi-platform wise). Any hint? -- Even if you are considered to be the most sinful of all sinners, when you are situated in the boat of transcendental knowledge you will be able to cross over the ocean of miseries.

[Survey] Forking Operating System Proces in Pharo

by Mariano Martinez Peck

Dear all, As I mentioned in the thread "Pharo Consortium Sponsored Development Effort" [1] I built a survey about Forking Operating System Processes in Pharo. The idea of the survey is simple: I want to understand what people needs the most, which features would be useful, which ones would not, what is missing, what is wrong, etc etc etc. As always, since we have limited resources, we should optimize them as much as possible. I count with you so that we can make a roadmap together on this project. Please, feel free to forward this survey anywhere where there could be an interest. https://www.surveymonkey.com/r/DHR22TL Best regards, [1] http://forum.world.st/ANN-Pharo-Consortium-Sponsored-Development-Effort-td4… -- Mariano http://marianopeck.wordpress.com

This was stuck because of Spur and FFI rewrite. The idea is that Morphic event should not come from the VM anymore but from the SDL pluggin these events should be turned into OSEvents so that the system is not poluted by SDL knowleldge (image that tomorrow there is a new standard we do not want to rewrite again eveything. > Package validation > > what those mean exactly ? You publish your great software in a pharo 50 distribution inbox and a robot runs and checks that all the tests are green the rules you indicated as "should be working" should work. This way is package XML is not working people will not get it in the Pharo distributino and they will not say Pharo is crap. I loaded XML and Pharo does not work.
