Re: [Pharo-dev] [Vm-dev] Re: Random forest in Pharo

by Esteban Lorenzano

Hi, just to be clear. When we talk about MTVM, we talk about a MT-FFI, *not* a MTVM in general. In general, a âcommonâ approach to MT cannot be applied in Pharo (or Smalltalk in general) and to get a VM *and* an image working properly is an effort that makes what I called massive some mails above like a small stone compared to a mountain. Said that: - What is in plans is MT-FFI, and that will be available eventually. - There is an approach I want to re-work, that would allow us profit of multicores without going multithread: the âhydraâ experiment made some years ago by Igor creates a good basis to this. But is also a lot of of work (but a lot less than a complete MT), and not a real priority for nowâ¦ I hope to resume work on that area some dayâ¦ just not anytime soon.

- Go back to UPBE -- Fix so now the complete book is compiled as a single pdf once again -- Document Spotter in Pharo Tour chapter -- Document Nautilus Icons in Pharo Tour tutorial -- Create Nautilus icons in 3d just for fun -- Integrate pull request by bpietro with several improvements -Give a slack a try -- Create a a dedicate channel in slack pharoproject , documentation, for talking about documentation -- Integrate github commits so people logged in the channel get informed about any new commits in our books -Ephestos -- Prepare for a Blender Pharo API. Until now Ephestos allowed pharo users to use the Blender python API even with pharo syntax and python syntax but I have decided to implement a new API completely in Pharo that will further simplify the process and guard the pharo users from Blender technical details and make controlling Blender from Pharo much easier. My goal is to create a povray ( http://www.povray.org/ ) kind of language , more or less, with pharo for scripting Blender. -Pharo auto completion -- Keep studying auto completion , unfortunately I still need time to make sense of things , but I have figured out the basics.

Hi Robert, Nice to see you! Looks interesting I know that Chris did something gathering sources of entropy. Seems like the more the better. Could you just make the entropy sources optional such that if they exist we use them? I would have to go back and see what Chris did but he was following suggestions from Schneider in his secureRandom.

Confusing Date parsing

by Torsten Bergmann

Also Date readFrom: '9.7.2015' readStream pattern: 'ddmmyyyy'. works, but Date readFrom: '23.7.2015' readStream pattern: 'ddmmyyyy'. throws an error. I'm confused...

The usual downside of splitting resources applies. There are not that many "others" and maybe they would be drawn away from helping with the 64-bit vm. If the 64-bit vm goes slower for lack of resources then your footing for MTVM will shifting for a longer time. You may ultimately get where you want to go faster by helping with the 64-bit vm. The rapport built with other vm devs from working on 64-bit might could then be applied to MTVM.

Confusing Date parsing

by Torsten Bergmann

'9.7.2015' asDate returns the 7th of September, I would have expected 9th of July because in Date readFrom: comment it is stated: readFrom: aStream "Read a Date from the stream in any of the forms: <day> <month> <year> (15 April 1982; 15-APR-82; 15.4.82; 15APR82) <month> <day> <year> (April 15, 1982; 4/15/82) <year>-<month>-<day> (1982-04-15) (ISO8601)" According to this the order day, month, year with a $. as separator should be valid. When I try '15.4.82' asDate als does not work, it gives an error that the month is exceeded with 15... Looks like this is not correctly implemented/backed up by tests. Or the comment is just wrong. Should I open an issue? Thanks T.

[Cryptography port to Pharo] RandomGenerator class>>unpredictableStringsDo:

by Robert Withers

This is a message intended for anyone who was on the Cryptography team. I recently ported it to Pharo and had to make changes to RandomGenerator class>>unpredictableStringsDo:. This certainly removed some uncertainty from the results of this message. My question is what should I do about that? This method seems to require non-headless, as it is checking the mouse point and such. This being a crypto cornerstone, what the best answer here. Thank you, Robert

Re: [Pharo-dev] [Vm-dev] VM Maker: VMMaker.oscog-eem.1492.mcz

by Robert Withers

I think I have a 32-bit ubuntu install so these changes may not make a difference. Although, would I be able to run 64-bit images in the simulator on a 32-bit machine? That would be very cool. I would still be interested in building the latest VMMaker generated code in Pharo. In search of training and guidance, is there a write up on which packages to load (Cog, Cog.pharo, CogVMMakerPharoCompatibility, VMMaker.oscog, ...)? thank you, Robert On 10/18/2015 12:33 AM, commits(a)source.squeak.org wrote: > > Eliot Miranda uploaded a new version of VMMaker to project VM Maker: > http://source.squeak.org/VMMaker/VMMaker.oscog-eem.1492.mcz > > ==================== Summary ==================== > > Name: VMMaker.oscog-eem.1492 > Author: eem > Time: 17 October 2015, 5:32:12.348 pm > UUID: a0778a36-b0e9-4e06-af1a-0e50572c9db1 > Ancestors: VMMaker.oscog-eem.1491 > > x64 Cogit: > Get the Cogit to a state where the 64-bit Spur image starts simulating.

interesting recursive out-of-memory error

Hi All, this in a bleeding edge Pharo 5 image which had been left standing with a Playground open which, when I clicked on it after leaving it for over an hour, got into an infinite recursion failing to allocate an object as part of opening a file to write an error report to.

Re: [Pharo-dev] [Vm-dev] Re: Random forest in Pharo

by Robert Withers

Yes, exactly. I do realize I was consciously changing that effort synchronization order. I was doing so with the idea in mind that I and others might dig into working on the VM, for threading support, while Eliot maintains focus on 64-bits...a tall order, I know. I was barely familiar with the VM, slang, interpreter, it years ago... I'm totally unfamiliar with cog. I believe another item on that list ought to be modernizing slang. So many big items!

review needed : step through package list by package first character (Nautilus package pane)

by Nicolai Hess

see issue 15184 Systembrowser package navigation inconsistent behavior I think this change would be a good addition. It makes it easier to find a package resp. navigate by typing the key for the package name first character. please try it out and give feedback.

Re: [Pharo-dev] RPackage design documentation

by Thierry Goubier

Hi Esteban, just be carefull if you start to play with it. Endless loops, code loss and other nasty issues may happen when RPackage (overall) is desynchronized from the state of the system. The concept is simple, but the time needed to get it right was very significant. It was redesigned once already. At the same time, any time and knowledge you may gain about the RPackage internals will be very valuable for the Pharo community.

(+vm-dev) Esteban, thanks very much for your views.

But we want to move Pharo to 64bitsâ¦ we are losing a train here... > - FFI MT and of course you are buried in existing tasks, especially the transition to 64-bits. It is my humble opinion, without really knowing, that 64-bit would have to be redone after the MTVM completes. Kinda why I would desire MTVM before 64-bits, then I assume less work would be needed overall. But that's my uneducated guess. Perhaps Eliot could shine some light for us on the progress of MTVM and what's needed. Because of that assumption I've made and without the responsibilities you have, Esteban, but recognizing modernizing NB to FFI, my desired list is: - NB to FFI port (should be ready soon) - spur32 bits (should be ready soon, we are just waiting the NB to FFI) - FFI MT - spur64 bits (Eliot is working on the JIT, I need to manage the migration of Pharo) - FFI 64bits (0% done hereâ¦ just some stubs waiting for effort). But we want to move Pharo to 64bitsâ¦ we are losing a train here... > If *anyone* wants to collaborate in any part of this list (is a MASSIVE effort), I would be very happy and willing to provide as much assistance/guiding/peer programming as I can. Yes, please, and I appreciate you willingness to mentor.

There is no magic here, if you want something to happen while doing something else, you need to provide a way to be called back when that thing finishes. now we have: nbCall:module: to call FFI (will change to a more generic ffiCall:module:, btwâ¦ but weâll keep old notation some versions to provide backward compatibility) So I can imagine an API like this: ffiAsyncCall:callback:module: So yesâ¦ you need change.

Re: [Pharo-dev] Random forest in Pharo

by Robert Withers

Bonjour Stef, I believe the change everyone would be waiting for is a Multi-threaded VM, that supports threaded callouts and callbacks. So I suppose the questions become: - will existing NB syntax require change with the introduction of a MTVM? - to what degree will NB syntax need to be extended to support threaded callouts. - what NB syntax changes are needed for callbacks. - timing: when is MTVM expected and can we operate on the leading edge? Personally, in SqueakElib, I have my network and session layers working for encrypted connections, so I just have the presentation layer to go. Once done, I would be very interested in working in the VM with whomever is also interested with an eye towards threading (MTVM). I am no expert here so it will be a challenge I am looking forward to.

In pharodays presentations we explictly mentioned our strategy: - we keep NB syntax - we change the assembly generation to be able to get Spur. Stef I can tell you that if I could get a lua kind of jit now I would sign immediately and also for having pharo as a dll. Now it takes time to do soemthing.

Re: [Pharo-dev] Random forest in Pharo

by stepharo

Personally I do not want to be forced to deploy R or whatever when I deploy Pharo. Period. We have enough dependencies to external libraries dll and other. If for one of your project you want to use a hyper cool super hyper coool external libraries then perfect. Not for Pharo. Now we should focus on what is important for core pharo and my remark is about the core. About the FFI, would be good that people stop complaining and help. We supported Igor NB (Laurent wrote a tutorial that I spent time to revisit even if I never did a FFI call) so where were you? Where are you pharoers when it is about to write something for the community? For your information we are in discussion with ronie (I do not know the status of his back-end), esteban spent 4 months working on a new FFI front-end using NB syntax and back end using FFI. The idea is that we can plug the back-end of ronie. Our team on his **own** money will invite ronie to work with us (Now we lost the money of our of our sponsors so times will be difficult).

Re: [Pharo-dev] RPackage design documentation

Most my documentations are in the tests I wrote. I spent more time in the tests than the code In essence a tag is just a label you can put to a class it does not influence the package. A package is a list of class definition a list of method selectors Read the class comment because it explains all path I followed.

Hi I will study the palette as defined in Roassal and extract a Palette class to be used in Pharo. My goal is not to do the perfect thing first but to gain some knowledge. Pointers are welcome. Stef
