Re: [Pharo-users] DBXTalk/Garage: GAMySQLDriver#execute: raises exception when int field is NULL

by Esteban A. Maringolo

I don't know about the instructions because I don't maintain the DBXTalk/Garage website. But for Pharo 5 the #stable/#release version is 0.5, which in the case of MySQL should load the package Garage-Mysql-GuillermoPolito.24. You should load it by executing: Gofer it smalltalkhubUser: 'DBXTalk' project: 'Garage'; configurationOf: 'Garage'; load. #ConfigurationOfGarage asClass project stableVersion load: 'mysql'. Regards!

Re: Pharo 5 accented chars bug/regression

by Milan Vavra

Thank you all, your feedback is appreciated. You have raised many points and so I probably won't be addressing them all. But thanks again for all. I did read all the responses. I will re-read them for more inspiration. I understand posting on this list is like going into a room with over a 100 people and saying something. So if 100 people spend 10 minutes to read this - that's a lot of minutes. So I don't want to waste your time. Feel free NOT to read this. But if you do read this, there is an attempt at a joke towards the end. You might even find it funny. Or not. I'm posting this through Nabble and it seems to post everything I post twice. Once as 'Pharo Smalltalk Users mailing list' and as 'Milan Vavra' too. I have no idea why. Enlighten me if you can. My original motivation was and is to be able to show to a potential employer before and/or during the interview the sort problem fixing that I can do. Even should the job have nothing to do with Smalltalk or Pharo (then it might be an opportunity for a little Pharo/Smalltalk evangelism but I digress). If there is an easy way to show that version X has a problem - then I can show that I have the skills to fix that. If it is fixed in the meantime I can just point to the fixed version Y and say: "yeah, I fixed that". If there is some supporting evidence that should give more credibility to my other claims that are unverifiable due to the fact that they involved proprietary code that I just can not show anyone. So their value in an interview is limited because it depends on trust or a reference from someone else (trust again but vested in the reference). But the Pharo fix should be an independently verifiable claim. Of course there is a chance that I hired someone to fix that issue for me and I don't have the skills. So a few follow up questions should be in order to see whether or not I know what I am talking about. On positive feedback. I think negative feedback is ok. Please do give me negative feedback. I can take it. It can point me to perceived problems I were not aware of. What I do want however is ***constructive*** feedback. Actionable feedback. If you have a strong opinion state it clearly but it should be of the kind: "To do [thing] is stupid/ugly/whatever. We/you should do [something else] because [explanation]." I think Peter raised the issue: "is it fair that everyone gets mentioned even though their contributions are not comparable". I am not ashamed to say: "YES!". However it is not the same as saying that what I can (potentially, you have not seen it yet) do is more valuable than what others did in making Pharo happen in the first place. I had a minor role in the movie. But I deserve a place in the credits. If there were no you (all of you who have contributed so far) Pharo would not be what it is today. A sexy development environment. If there were no me, someone else would have to step up and do what I did. I am fully aware of that. Me trying to contribute is a "thank you" of sorts to all of you. Small contribution with big impact. In a way it is not that small a contribution considering the impact it can have on Pharo adoption. In Smalltalk "a little code goes a long way". Consider this scenario, a true story: I first downloaded my first Pharo back when 3.0 was new. On Windows XP. I played with it a little. Got excited (sooooo sexy!). But then came the blow. What? I can not type Ä? Is my keyboard broken? Severed cable? No? Oh ok. It just won't let me. There goes my contact management application. Bummer. It seems the IDE is not used by anyone in the Czech Republic on Windows. Otherwise someone would have noticed. Oh. Well. I don't have the skill to debug this yet. I am not sure how to report this. Oh well let's wait until someone fixes this. And it gave me the impression Pharo 3.0 is immature technology. This could be happening in any country that uses Ä as part of their language - Latvia, Lithuania, Serbia, Slovakia (Russia, Bulgaria, Croatia - for the russian characters). A year later Pharo 4.0 came out and it still was not fixed. Then Pharo 5.0 - same story. I have been learning Smalltalk in small steps on Squeak and Pharo trying things from SBE and PBE and my contact management example based on an excellent video by Laurent Laffont. To cut a long story short only this month I have reached the point that I was thinking maybe now I have what it takes to fix this. And the excellent videos of the Pharo MOOC definitely played a part too. Thanks to everyone involved. Anyway I tried to debug this issue and it worked. So what if you were able to wave the magic wand to make that bug go away? I have that wand. I'll see if I can jump through the hoops of the contribution process although it might take some time. On a lighter note, I had a bright vision of how I could get some credit for being able to fix this. I would find hire some really hot hostess or two for an upcoming Pharo conference in Prague. They would have the following on their T-shirts. One: 'Ä, Ä, Ä, Anyone?' and the other 'Ð ,Ð, Ð, Ð, Ð, Ð, Anyone?' and 'Ask me how' on the back. :-). And their job would be to hand out my email address to anyone interested. Or even point to me standing in the distance. I bet they would command some attention. Mentoring. It would be nice to know how to find a mentor for the contribution process, possibly beyond.

Re: [Pharo-users] Don't understand Array creation syntax

by Damien Pollet

I don't understand what you've understoodâ¦ Parentheses need to be paired for the outer literal array to be recognized. Technically, opening parentheses could become elements, but not closing parentheses, since then there would be nothing to close the literal array. And it would be strange to read if you could have several ((( but only one ) at the end. Instead, pairs of parentheses enclose an array, which is nice because it makes it possible to have literal arrays as elements inside literal arrays. If you want a single parenthesis as an element, you have to explicitly write is using the symbol syntax.

Re: [Pharo-users] [Raspberry Pi] Accessing GPIO pins on Raspberry Pi?

by jean baptiste arnaud

Wiring pi imply that you configure a little bit GPIO also. Small manipulation that I do not remember really well. You can check http://wiringpi.com/reference/setup/ If I remember well, you need also i2c. I now that you need to setup it before using GPIO. The code was proof of concept and early binding of the wiringPi it is incomplete but you should be able to blink led. The VM do not had been update since a long time (It will be re-up soon), so with WiringPi and a 4.0 should work. In 5.0 I do not know depending if there are some change in FFI in the image side. ------ Message d'origine ------ De : "Thierry Goubier" <thierry.goubier(a)gmail.com> Ã : "Any question about pharo is welcome" <pharo-users(a)lists.pharo.org> EnvoyÃ© 14/06/2016 11:36:55 Objet : Re: [Pharo-users] [Raspberry Pi] Accessing GPIO pins on Raspberry Pi? >Hi Steven, > >I'm also interested.

Re: [Pharo-users] [Raspberry Pi] Accessing GPIO pins on Raspberry Pi?

by Henrik Johansen

There doesn't seem to be many Pharoisms in WiringPi; for a much snappier experience, you might want to check out Squeak instead. Raspbian ships with both Spur and Non-Spur VM's included (courtesy of Scratch) which include optimized BitBlt primitives (may be absent from the old Pharo VM) + it uses bitmap fonts and has less configurable, but faster tools. Since WiringPi uses FFI though, you'd have to find and load that manually before the actual WiringPi package, no metacello config for squeak afaict.

Hi Steven, I'm also interested. I'll received a Pi 3 soon and I'll want to use the GPIO as well, as well as looking at performances issues, especially at the IDE level. Have you tried to use: - command line manipulation of the GPIO via OSProcess ? Create a GPIO file access: echo 11 > /sys/class/gpio/export Configure the Pin Direction (In/Out): echo out > /sys/class/gpio/gpio11/direction Write a value to turn on the LED using the GPIO11: echo 1 > /sys/class/gpio/gpio11/value *Now your led should be ON!!!* Write a value to clear the LED using the GPIO11 echo 0 > /sys/class/gpio/gpio11/value *Now your led should be OFF!!!* Delete the created GPIO (11) echo 11 > /sys/class/gpio/unexport (you can run those commands from Pharo) Those commands reach ~ 4 kHz on toggling on or off a gpio pin.

My bad, the leds were not on the right pins. Now all my leds are off and my wiring is ok. It still doesn't work, but i'm not sure whether my setup is wrong or if it just doesn't work anymore on Pharo5. I will attempt to use the library outside Pharo, reconfigure a Pharo image & vm and then try it again. In the meantime if anyone does success at this, please let me know i am very interested by using the GPIO pins from Pharo. Steven.
