[Tim Mackinnon]

It’s very exciting watching the progress both in these email updates and the 
excellent more visual tweets.

This and the progress on Pharo 7 will make for a great Xmas!

Re: [Pharo-users] problem when running without changes file (on windows)

[Vincent.Blondeau]

Have you seen https://ci.inria.fr/moose/job/moose-7.0/ ? Roassal is loaded on 
it.

Ok, thanks for this crucial information! Would backporting be as simple as 
filing out the class and the single method from Pharo7 and filing in in 
Pharo6.1 ? (probably not)

 

I could also move y application to Pharo 7, but sofar I haven’t been able to 
load Roassal2 in Pharo 7 (32bit). Any information on how to achieve this (on 
windows)? No Moose 7.0 image with Roassal preloaded available either, AFAIK...

Still, in Pharo6 the absense of changes and sources files means also that FFI 
calls cannot be done.

UFFI uses the method source code to map arguments, and if no source code is 
available, FFI calls cannot be resolved.

 

This is solved in Pharo7 thanks to Vincent Blondeau by embedding argument names 
into the method (and thus not requiring source code anymore).

 

If you need it, you can take the FFICompilerPlugin class + 
(RBMethodNode>>ensureCachedArgumentNames) from Pharo7 and try to backport them 
on your Pharo6 installation.

When I run the application with the changes file present all is fine. When 
running with the changes file removed, it mostly works ok but apparently the 
functionality for e.g. creating png (linked to Cairo?) is not available. The

Hi,

 

You may want to look at https://github.com/VincentBlondeau/Cruiser that 
contains all the actions needed to perform a clean packaging (Still in dev 
though).

The only issue is that it works for Pharo 7 only and you’ll need to backport 
changes (I can help you on that). Some changes are related to new VM primitives 
so you have to use the current stable one (which should also running the Pharo 
6.1 images).

 

Don’t hesitate to ask me if you need advices or help on this.

 

I could try to make the tool work on Pharo 6, but it could be incomplete 
especially on the FFI and stdio part.

 

HTH,

 

Cheers,

Vincent

While not completely sure, I think they actually could work. Maybe you found in 
the way a couple of other methods to backport, but I think that it should not 
be that difficult.

 

This is the original issue that fixed this in Pharo7:

 

https://pharo.fogbugz.com/f/cases/21124/FFI-should-work-without-the-sources 

 

 

And here the PR with the fix:

 

https://github.com/pharo-project/pharo/pull/739 

 

 

There are a couple of more changes there, but not so many.

OK, I'll bite.

What does "code the competition" mean exactly?

I last used Smalltalk "in anger" pre-pharo with squeak.  I live ST and am 
looking for a way back "in" but
TBH the changes from Squeak are vast and I have too many ideas to work on and 
keep hitting walls.

I'm intrigued but need more direction.  Whatcha need - ELI5.

Re: [Pharo-users] My Keynote at the Salta Conference

No, the money isn't lost. I was merely suggesting that without some help, the
marketing opportunity for this competition would be lost.

I'm not sure you understand how much work is involved in this project. I
will be doing a great deal of the heavy lifting. I have to setup the
competition website server. I have to advertise or reach out to high schools
across the country. I have to get local media interested in covering the
competition. I have to look into producing the T-shirt swag, and shipping
the T-shirts to all contest participants, and at an affordable rate to fit
the budget. Those are only a few things off the top of my head.

Coding the actual contest problems according to David Buck's prescription
shouldn't be open-ended and shouldn't be a huge commitment. I imagine it
would be a couple of months of work during spare time.

Your request is really open ended and while maybe not you intent, sounds
like you want someone to deliver the whole thing for you.
That could be a 10 to 20 day commitment at a $1000/day - who knows from the
scope you've presented.  Its like your asking for a blank cheque.
And it "feels" like the full onus would be on the developer and that
responsibility can be off-putting.
Even people that may be inclined to help may not have the spare cycles for
that commitment.
They can be already be doing a *lot* of volunteer time to help Pharo which
suits their priorities.
Even people who believe your project is a priority may be caught up in
commitments they can't drop.
So there are a lot of precondition hurdles you need to hurdle to get
helpers.

So what you are doing is kicking off an "new" open source project.
And further, in essence what you are doing is building a mini-community of
helpers (even if that is one helper, and notice the distinction from pure
volunteer).
Now as ESR says... "When you start community-building, what you need to be
able to present is a plausible promise. Your program doesn't have to work
particularly well. It can be crude, buggy, incomplete, and poorly
documented. What it must not fail to do is (a) run, and (b) convince
potential co-developers that it can be evolved into something really neat
in the foreseeable future."

> I am nowhere near qualified to do so, as my knowledge of Pharo is limited.
>>

This is a red herring.  The majority of your "plausible promise" is the
model, with unit tests demonstrating its operation.
That should be able to be coded platform independently.

When you progress to needing platform specific knowledge (e.g. gui,
networking, web framerworks)
you can start by asking specific questions in relation to your "plausible
promise".
You can encourage people can install your "plausible promise" on their
machines to provide concrete examples to help the discussion,
The trick is, once someone has installed your "plausible promise" and see
it working in their infancy it becomes much more real for them,
sparks ideas for small improvements and they are *much* more likely be
inspired to help you.

So personally, in general I'm open to helping (and I'm quite susceptible to
being deeply drawn in)
I'm just not inspired enough right now to drop any of my other commitments
to take the lead with this.

Frankly to imply otherwise is off putting and doesn't help you case.

Getting no takers within a few days doesn't mean the end of the line.
It means that there is something wrong with your strategy.
I've given you a few tips.  I hope you can adapt and persevere.  It would
be great to see this succeed.

Please flood us with any technical questions you need to overcome.
Very happy to help in this regard and it builds your presence and people's
familiarity with you and the project
and *then* you are much more likely people are drawn in to become involved.

Hi Richard,

So the  that we gave you is now “lost"? Perhaps people didn’t understand 
what you expected from us other than money. What else is needed to make your 
project a success? We are supposed to “code the competition” as well? Anything 
else?

Is this practice of insulting people (“Doesn’t anyone care about promoting 
Pharo?”) supposed to be motivating? Is it a demonstration of you expertise at 
marketing? Does it build confidence about how the Smalltalk community will be 
perceived by the new arrivals?

I’ve appreciated your blog posts and your passion, but I’m put off by this 
approach.

James

P.S. I realize that I’m probably doing what I’m criticizing in you—throwing out 
negative comments from behind a keyboard to score points when I might not be so 
harsh in person.

[Pharo-users] Commit dates when migrating repos to github

[Ben Coman]

Just a quick note sharing something I learnt recently.

When migrating MCZ repos to git, set the commit-date of the first empty
commit back past the first MCZ date.
https://leewc.com/articles/making-past-git-commits/

After the MCZs have been exported, check the commit-date matches the author
date.
$ git log --format=fuller

or otherwise force it so...
$ git filter-branch --env-filter 'export
GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"'

Re: [Pharo-users] Reify RBLiteralNode and RBBlockNode args/return with MetaLink?

[Marcus Denker]

I already have a fix for i) i) How do I reify the value of an 
RB(Valuel|Literal|LiteralValue)Node? 

I will commit it later today.
