www.smalltalkhub.com not reachable from digitalocean host in NewYork2

by Yanni Chiu

I can ping: www.smalltalkhub.com (88.190.31.116) from two other machines (home and another host provider), but I cannot see 88.190.31.116 from a digitalocean box located in NewYork2. I can see squeaksource.com, ss3.gemtalksystems.com, ci.infria.fr but not smalltalkhub.com. Very frustrating, since I want to run my build from this machine. Any ideas? Is it on some sort of ban list? The firewall rules allow all outgoing connections.

Pharo Wiki cleanup

by Camillo Bruni

In my attempt to make the contribution process for Pharo a bit simpler I cleaned up the fogbugz wikis which where left a bit unmaintained. There are now 5 important top-level categories: Welcome Page: https://pharo.fogbugz.com/default.asp?W41 Documentation: https://pharo.fogbugz.com/default.asp?W69 Changelog: https://pharo.fogbugz.com/default.asp?W2 Wishlist: https://pharo.fogbugz.com/default.asp?W50 Responsibilities: https://pharo.fogbugz.com/default.asp?W66 I removed old cruft that was documenting long gone features of ancient pharo versions ;). I would be more than happy to get some feedback and improve these websites gradually.

Re: [Pharo-users] New Mars examples: Package Browser and Test Runner

by Esteban A. Maringolo

I love native windowing. This looks really well! This statement from your blog: "Now I really think that âmore handsâ should be involved to grow and improve this working version." It is really important. There are lots of interesting projects and tools that were practically abandoned because the creator dedicated his/her time to something new. Pareto principle everywhere.

New Mars examples: Package Browser and Test Runner

by Carla F. Griggio

Hi everyone! I want to let you know that I've just posted a screencast in my blog about the new Mars Package Browser and Test Runner<http://marsonpharo.wordpress.com/2013/09/24/marspackagebrowser-and-marstest…> . These examples are not really intended as being the definitive package browser or test runner, but to start experiencing how is it to build a real application using Mars and to showcase some widgets. Anyway, it's cool :) The Package browser is not so different to the system browser example I showed before, but the Test Runner is definitely my favorite example so far. I give more details in the screencast<http://www.youtube.com/watch?v=RlBr42uaqxE>and the blog post<http://marsonpharo.wordpress.com/2013/09/24/marspackagebrowser-and-marstest…>. Any feedback is appreciated! Cheers, Carla.

Encoding issues with DBXTalk

by Esteban A. Maringolo

I'm trying to search for an object in the database by means of the following query: session readOneOf: User where: [:one | one name = 'MartÃn']. There is no matching row in the database. But I get the following error: DBXRecoverableError: RECOVERABLE OpenDBX: ERROR: invalid byte sequence for encoding "UTF8": 0xed 0x6e 0x27 On the other hand, if I insert a row manually, when I get the name back (read from the database) I get 'MartÃÂn' instead of the original 'MartÃn'. Should I define the encoding I want to use somewhere else? Regards, Esteban A. Maringolo

Maybe you should use MethodWrappers. http://forum.world.st/MethodWrappers-td3829576.html On 09/23/2013 09:56 AM, Alejandro Pulver wrote: > Hello, > > I would like to intercept all messages sent in the system, as part of a > small project to investigate if the information can be used in useful > ways (autocompletion, object compatibility detection, etc). > > It will also involve filtering, aggregating and enabling/disabling it > for space and time conservation, > > I'm new to Pharo, but had some success by changing the main perform > (perform:withArguments: IIRC) method in Object, and making others use it > instead of the primitives. > Someone told me it doesn't capture most messages because of > optimizations done by the system. > > My other thought was to use the profiler's spyOn as an approximation. > > What do you think? > > Thanks in Advance, > Alejandro

Capturing messages

by Alejandro Pulver

Hello, I would like to intercept all messages sent in the system, as part of a small project to investigate if the information can be used in useful ways (autocompletion, object compatibility detection, etc). It will also involve filtering, aggregating and enabling/disabling it for space and time conservation, I'm new to Pharo, but had some success by changing the main perform (perform:withArguments: IIRC) method in Object, and making others use it instead of the primitives. Someone told me it doesn't capture most messages because of optimizations done by the system. My other thought was to use the profiler's spyOn as an approximation. What do you think? Thanks in Advance, Alejandro
