Re: [Pharo-project] [squeak-dev] Experimental Cocoa OS-X based Squeak Cog JIT VM 5.8b4.

On 4.2.2beta1 these keys work as expected. I have to mention that I am still on Mac OS X 10.5.8. Perhaps the others are on Snow Leopard. Could that be a difference?

Are there any tests we could do to see the improvements? You can use the frame rate morphic to observe the rate rate you get in your application, compare to 4.x. Comparing to a 5.7 in 64bit mode may not be fair because with the same open/GL code it does a frame rate 25% better. I'm also interested in any drawing issues, yes it does lose it's mind when you resize the window (I might fix that someday), but I'm more concerned about drawing artifacts & visual differences between it now and 4.x -- =========================================================================== John M.

Ok, so I have Ken Brown & Mariano Martinez Peck saying the cntl-arrow keys work, and Tudor Girba saying they don't work. Obviously I need someone to document the behaviour in a 4.x VM and then in 5.8b4 so we understand what happens or doesn't happen. On 2010-08-29, at 7:45 AM, Ken G.

This is always a risk in any true open source software. Of course there are ways to avoid losing control even with very permissive licenses like MIT, like hearing your contributors, your porters, etc. That way the need to do a fork is minimized. If you discard good code for bad reasons you're most surely betting for a fork. Now, you can work only in VisualWorks, and some people can port (that is not the same as fork) to other platforms. In the way they can send you patches that make the original upstream version less platform dependent so that the porting is easier with time to new platforms, this is good for the project because can reach more platforms if it is really open in the development and contribution process. > I dont like several incompatible development streams for different dialects. And I would like to integrate contributions myself. > This don't need to happen, there are libraries (Sport, Grease) that put a layer between platform specifics and your code so that is easier for maintainers of the different ports to stay compatible. But again, the principal reason of forking is contribution process issues and not platform specific issues. > One way to do this is to have the primary implementation in VisualWorks and a reliable, not too intrusive way of exporting it to other dialects.

Don't worry about this right now. Just put a working version for VW and someone (I for sure) will step forward to contribute the porting to pharo. > Any thoughts about such a procedure?

There is NO way to have native Smalltlak driver for propietary databases. Even if I would love to have the database driver implemented in Smalltalk rather than calling a C library, this is not possible with propiertary databases. If you don't have a public protocol or API there is no way to build the driver. Do you think Oracle or Microsoft would do a Smalltalk driver? I doubt it.

[Pharo-project] OSProcess - can it pipe 1 MB?

by Schwab,Wilhelm K

I am trying to pipe roughly 1 MB of data into a program on Linux; I know it can handle the load, because I have tested it with by cat-ing a script and the data. I do not yet promise that my Pharo code is correct; if the program did not respond or returned junk, I would look to myself. But I am getting errors suggesting that AttachableFileStream is failing on writing to the pipe, and it's very suspicious that it simply can't handle the size of the string. Any ideas? Bill

My two cents long time in my blog on exactly the same subject: Its great to see a free version of Smalltalk at last measuring up to the needs of using it in an business sense and showing it to non-Smalltalkerâs and the âIT managersâ and not put them off. I am sure this is going to make it difficult for VA and Cincom to create new small-medium shop sales going forward especially with Seaside, Magritte and raft of other frameworks actually being born in Squeak. There obviously is the crying need for High Priority: Enusure very high reliability of the base Pharo. No bugs that are not fixable by the average developer with a bit of google and sending a few emails. If it needs that one expert in one other end.. business continuity is hugely impacted Primary: * better-faster VM aka Cog mainstream * Highly performant DBMS connectivity natively akin to JDBC through to all DBs no DB specific stuff like now, the Squeak DBX is not business friendly. * Comprehensive Web Services + XMLRPC * Pharo-Groovy bridge and / or Pharo-Ruby bridge ( or can we make Pharo work in tandem with a JVM..! this will help leverage the tons of frameworks in existence even if they are tad slower than native Java) * Configuration Management System plugin for SVN * Acceleration of easy docs and plugins/ web development related framework interfaces from Seaside viz flex/ silverlight: many that are possible as of now, but needs a Smalltalk expert to cobble it up * Have not really gone deeper with Webclient/ FTPClient/ SMTPClient et als. they need to be really simple/ highly reliable/ dumbed down for the average coder to pick snippets and make it work May be lots more.. I can bring in lot more thought this in terms of Generic/ Sectoral or Domain/ Type of Apps preferences viz: Banking/Insurance/Utilities/Technical/ Web vs GUI etc ...So first we should think hard on the segment you want to hit harder.. Secondary: * Better tools for GUI Dev and more standard GUI development capabilities * Make Pharo easily usable for a team of 100+ developers together in one/multiple locations with code synch issues, change / version control , performance ( a host of other stuff included) taken care of. * Pluggable to industry standard tools for development: Rational/ Together Soft viz for UML creation and conversion to code / reverse engineer code to UML Follow through with: * Pluggable with QTP/ Testing Automation tools.. Actually this is very important in the standard large volume development. Makes a huge difference for the risk mitigation for the company. really inexpensive , kind of not so highly technical staff runs this show in comparison to Unit Tests/ test automation through ST code is a more riskier investment and I have not seen in JAva/ .Net / or even Smalltalk large legacy projects unit test done and maintained well enough -Skrish
