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

by Mark Bratcher

Esteban I think this is a versioning issue. The installation instructions for DBXTalk/Garage show 0.1. I looked all over the DBXTalk website, and the smalltalkhub.com location for the package, but I couldn't find any listing of what version is the latest to use. Do you know what the latest version is I should pull? Thanks Mark On 6/13/2016 12:06 PM, Esteban A.

Sven could you update the class comments of such classes and we should finish to get rid of them. Your solution is much nicer.

I do not know. And someone should do it and this is at least a week of work. Then the problem is that we should help students. Now if you have more information I would be interested. Stef

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

by Steven Costiou

Hi, i have tried to make it work but so far i can't get it right. Have you been able to work with it ? I used pharo 5 latest non spur image with the non spur vm. It works on a raspberry 3 but it is very slow. I tried the led examples, the leds do not seem to be affected (some are on, some off, with a variable intensity). Is there any specific settings needed for this to work ? Thanks, Steven.

Hi Milan, First of all, welcome in our community. We do not maintain StackOverflow and the experience that you have there is not representative for our project. This mailing list(s), the Slack team and the issue tracker are. Btw, debugging for 2 days is a great way to start learning Pharo. And we do appreciate the effort. Please do engage with us.

>From what I have seen pharo on stackoverflow has becoming less and less active when we created the Slack channel. Also this mailing list helps a lot. I used to be a supporter of stackoverflow but I have to agree with others, its moderation is beyond stupid. I also found some tricks to make managing the mailing list easier, I created filters in my gmail account to gather anything concering pharo and put it in one place and I use Thunderbird to make the experience smoother. Mailing list and Slack is all we need.
