Can you help me find this info?

by Victor RENE

Hello, I am new to Pharo and would like to understand a few things. I can search by myself, but I do not know the code base yet, so: [Questions] Pharo image: Serialization, deserialization, where is the code? Pharo vm (Cog/Spur): Rendering loop and event loops. done with SDL2, where is the code? Message passing, object hierarchy lookup, where is the code? Pharo minimal: How to get a working version? The builds I tried (4.0) crashed. [Purpose] My goal is work out an image/vm with minimum overhead. For example, let's say I want to build a modern multi-touch application. Pharo's environment looks promising on the live coding/debugging side, but what about the performance? Lack of responsiveness would not be acceptable (think about design differences between Android/iOS). [Context] I want to understand if the object oriented nature of Smalltalk is the reason for the lack of apps of this nature (as far as I can tell). For example, games have been done with Lisp: Jack and Daxter (on the PS2, by Naughty Dogs). There are also game engines for the JVM (https://www.lwjgl.org/) Dedicated hardware has been built for either Lisp or Forth. I can't seem to find any hardware built specifically to power Smalltalk software. Yet as far as I can tell, it's the big time for software virtual machines, because the new generation of hardware will be supporting them. (https://news.ycombinator.com/item?id=10032295) UPDATE: I am reading through "Evaluating message passing control techniques in Smalltalk" (https://www.researchgate.net/publication/2440118_Evaluating_Message_Passing…) I am getting a better picture of the whole, please direct to more such papers.

Transcript clear works for me in Pharo 4 and 5 images.

What version of Pharo? `Transcript clear.` does exactly that. :) On Mon, May 2, 2016 at 8:49 AM, phil(a)highoctane.be <phil(a)highoctane.be> wrote: > I am looking for a way to clear the Transcript. > > There is no direct command like Transcript clear available. > > I do not want to reopen a new one, just be able to clear one with code, so > that I can leave the window placed properly where I want it. > > TIA > Phil >

Best way to clear the Transcript?

by phil＠highoctane.be

I am looking for a way to clear the Transcript. There is no direct command like Transcript clear available. I do not want to reopen a new one, just be able to clear one with code, so that I can leave the window placed properly where I want it. TIA Phil

You have also Natural Smalltalk from hernan. It sounds like a good basis.

for NLP Olivier started to work on Phonetix Now there is https://github.com/mark-watson/nlp_smalltalk But the lince is GPL3.0 and it looks simple... not sure it is worth to polute your life with such license.

marcus may be we should slowly deprecated ast into cachedParseTree or something like that. Le 30/4/16 Ã 22:25, Sean P. DeNigris a Ã©crit : > Why does CompiledMethod understand both?

Hello, I added a "MachineLearning" repository to Smalltalkhub a while back, but I got sidetracked before adding anything beyond a naive KNN classifier, which was really just to help prototype the testing framework. That said, my plans involve expanding the library extensively this summer in conjunction with my research, starting in about 6 days. I work on natural language processing, so it is possible that I was already planning to build some of the models you were intending to use. What models were you looking for? I also added a parallel NLP repository, which is similarly barren but for a naive IBM Model 1 translation model, which probably won't help you. Relatedly, I was contemplating building an RSS classifier myself, and would gladly use one, were it to exist.
