September 2019 - Pharo-users

Re: [Pharo-users] FFI beginner question

by Richard O'Keefe

What I want to do is to create a binding for the SoftPosit library. A typical function has an interface like quire16_t q16_fdp_add(quire16_t, posit16_t, posit16_t); where typedef struct { uint16_t v; } posit16_t; typedef struct { uint64_t v[2]; } quire16_t; A "quire" is a dot product accumulator. A "posit" is a number. {quire,posit}{8,16,32} are defined, and a number of other types.

Re: [Pharo-users] Reminder: Smalltalk Webcamp, 22nd of October

by Steve Quezadas

This is way too far for me. I am going to the one in portland in a week though. Also, it's nice to know where these pharo smalltalk conventions and camps are. What is the best way to learn about these? Through this maillist or is it posted somewhere?

Guillermo, I'm interested in helping, but at this point, I think I'd be most helpful working at improving documentation (mainly editing) rather than working on Pharo code itself. (I'd like to work toward that, though.) I'm still a newbie with Pharo, but I am a good writer/editor. And I expect that working with Pharo documentation would be another means of increasing my knowledge of the Pharo ecosystem -- so that's additional incentive for me. I gather that the PDF books are written using Pillar, which I know nothing about. Are there resources & guides for this tool/format that would help me learn how to make & edit these kinds of documents? Also, I've never contributed to an open source project; Pharo seems to be a good place to start doing so. I see that most of the documentation, web pages, booklets, etc. are in English so there's the advantage that English is my first language (and I actually paid attention in school :^). I'm also aware, from experience, that Documentation is rarely the first choice for developers to apply their time & enthusiasm... -Ted -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Code of Conduct

by Offray Vladimir Luna CÃ¡rdenas

But your reading of non-interest in CS within the sub-culture of blacks and women is a confirmation bias, reading from numbers in a circular fashion: low inscription numbers in sub-cultures show a non-interest, which is confirmed by those low numbers. I can tell you first hand that my impossibility to assist yearly to ESUG is not because the non-interest in the "Colombian subculture", which I belong to, about live coding or Smalltalk. In fact I learned Pharo by making Grafoscopio[1], despite of poor OOP undergrad classes and thanks to a self/family funded PhD studies that were *not* on computer science. But I know people here that is willing to learn and they don't have proper time/resources to do it. Despite the Colombia visa issues (and stupid jokes about Escobar at immigration and else where, because a Hispanic with a different visa has different issues, or not) and despite of the funding issues or my self learn English, that make my participation difficult in international events, I have privileges that many around have not. Instead of making them invisible, thinking in technology/code as being build "ex nihilo", disregarding context and people involve in such endeavors, I try to deconstruct them and be inclusive. That's why I care about diversity and respect being explicit in the community (for example in the CoC) [1] http://mutabit.com/grafoscopio/en.html But as said, your contributions to the project and the soundness of your arguments on the source code repository via PR, will be the more heavy that the longest mail thread we can have here.

Re: [Pharo-users] Where did all the Comments Go?

by Marcus Denker

Hello, This looks to me like a case where, due to some unknown reason, the image can not store the source in the .changes file. I have no idea why this happensâ¦ but it would explain why the comments disappear (as the comments are only in the source stored in the .changes file). > On 20 Sep 2019, at 23:59, Andrew Black <apblack(a)pdx.edu> wrote: > > My third attempt to post this ... > > Iâm coming back to Pharo after not having used it for several months.

Normally, SmaCC stores oneâs whole grammar _as a method comment_ in a method called definitionComment.

It looked fine, but as soon as I moved Calypso to another method, and then back again, the comment had disappeared.

Rather it is a code storage problem. I saw a File System primitive failure when I launched my new image, but ignored it; Iâm guessing that the comments disappear because they are only in the file system, whereas the code is in memory.

Re: [Pharo-users] Code of Conduct

I am a dark-skinned hispanic male from the United States and have not experienced any discriminatary practices whatsoever. Nor have I witnessed anything that I find that "is a problem" in the tech world. As far as "colleges are set up to make it easier for white males to succeed" is patently false. Most colleges, at least in the united states, are very biased to left-wing political views. So no.
