Re: [Pharo-dev] [Pharo-users] What is the craziest bug you ever face

by Dimitris Chloupis

For me it was when I was making the CPP library. CPP for those that do not know is a library I made that allows Pharo to control a C++ application. Its a very simple IPC bridge using shared memory mapped files. I was surprised how easy it was to make it from the C++ side Pharo side was a different story. UFFI is brilliantly simple to use BUT, as much as the Pharo rocks for debugging Pharo code it works under one caveat. The caveat being that your code makes no usage of UFFI or any FFI. Because the Pharo debugger has no means to debug UFFI. People may not realize it but practically UFFI is C coding. It make look like your usual Pharo code but make no mistake its C all the way. So the practice is to make sure the code works in C first. However if it works in C but for some strange reason it makes Pharo freak out you are all by yourself. Pharo code that can crash Pharo is the one that needs debugging the most. So to find these bug which fortunately there were not many I had to crash Pharo countless times and move extremely slow and step by step. None the less I success was the final result and I learned a ton in the process.

Re: [Pharo-dev] ExternalForm was removed 10 days ago in 60413

by Pavel Krivanek

It's own please, because it is a subclass of Form and in UnifiedFFI it would make a dependency of FFI on graphics -- Pavel 2017-03-09 12:15 GMT+01:00 Esteban Lorenzano <estebanlm(a)gmail.com>: > wellâ¦ it was removed and I put it on OSWindows-SDL2 because it was the > only place where it was being used. > We can move it again to a more general place (Like UnifiedFFIâ¦ or itâs > own). > > Esteban > > > On 9 Mar 2017, at 11:54, Aliaksei Syrel <alex.syrel(a)gmail.com> wrote: > > > > ... and was moved to OSWindow-SDL2 as OSSDL2ExternalForm. > > > > If we require external form but don't want to depend on OSWindow what is > the right way to go?

Re: [Pharo-dev] Archive Page for Pharo TechTalks

by Dimitris Chloupis

I kept the first few talks in this repo https://gitlab.com/Kilon/pharo-techtalks/tree/master I have mentioned it before but I mention it once again to remind people or maybe you want to add those to the website. Its easy to link directly to each audio file if you want.

Still happen at times but it has been fixed and now I get a usual 1mb/s and I feel like I am in heaven. I use monticello and Spotter all the time, Spotter never went cookoo on me. Monticello on the other hand has this bad habit when one makes a local commit, I am using only git with pharo for ages now via filetree, of contacting servers which to me at least makes zero sense , after it was explained to me why it became bellow zero sense. So basically if the connection is dropped , Monticello fails which is bad , but if connection becomes slow, Monticello freezes which is much worse. And to be Frank once more, I have stopped (not completely I still using it part time) using Pharo since I failed to integrate it to my workflow and I am back coding in Python for reasons that are technical and personal. Nonetheless I want to see Pharo succeed and for doing so we live in a time that simplicity of code design is a huge deal to a world of ever evolving more complex code. So my object is simple: Do not make Pharo code more complex , please. Of course I can be blamed for wanting to turn Pharo into Python, but I do not mind such blame.

Re: [Pharo-dev] ExternalForm was removed 10 days ago in 60413

by Esteban Lorenzano

wellâ¦ it was removed and I put it on OSWindows-SDL2 because it was the only place where it was being used. We can move it again to a more general place (Like UnifiedFFIâ¦ or itâs own).
