I love it now can we use it for a real clock? I mean do we get the warrantie that 1 min is 1 min? BTW we will have to write a nice animation chapter!

Re: [Pharo-dev] Bloc Animations

by Stephane Ducasse

And this is cool because your animation is not dependent on the machine speed Of course a faster machine means smoother animation not shorter one :) On Sun, Nov 26, 2017 at 12:13 AM, Aliaksei Syrel <alex.syrel(a)gmail.com> wrote: > Hi Sean, > > In Bloc it is exactly as described in the forwarded email.

Re: [Pharo-dev] I love the launcher!!!!

You can click on the setting of Pharo launcher Now they do not list theme :( In the setting if you "enable dev" you get access to the full pharo and there you can chose the theme you want.

Re: [Pharo-dev] Pharo 32bit on debian 9 stretch 64bit

by Norbert Hartl

Cyril, basically it should much more easy to install the vm on debian than what you described. The problem is that nobody put the updated installation instructions on the web site. Here they are http://forum.world.st/Latest-Debian-Ubuntu-and-CentOS-packages-of-the-pharo… <http://forum.world.st/Latest-Debian-Ubuntu-and-CentOS-packages-of-the-pharo…> The problem with it is that it won't help you at the moment. Last week we discovered that problem that debian 9 uses libssl 1.1 and that does not work with SqueakSSL plugin. The problem has been identified and Holger submitted a patch for the problem. https://github.com/OpenSmalltalk/opensmalltalk-vm/pull/174 <https://github.com/OpenSmalltalk/opensmalltalk-vm/pull/174> But there are even bigger problems. The current vms are in a bad shape. And it is really hard to get a patch in the vm. So there is no ETA when this will work.

Linux vm packages

by Norbert Hartl

Can we change linux installation instructions on the web site? I can't believe they aren't there, yet. Here is the description. http://forum.world.st/Latest-Debian-Ubuntu-and-CentOS-packages-of-the-pharo… <http://forum.world.st/Latest-Debian-Ubuntu-and-CentOS-packages-of-the-pharo…> This describes what to do for some linux distributions not only ubuntu. In the mail there are opensuse URLs. The all contain the word "latest" which means the development version. If this is exchanged with "stable" you get the stable version. The rest stays the same. I really should have checked this. Because it is just stupid that people spend a lot of work into that and it is not used nor published. If I can help please say so!!!! Norbert

Re: [Pharo-dev] Is SmalltalkCI working for Pharo projects?

by Ben Coman

The Raw Log of https://travis-ci.org/ba-st/Willow/jobs/307025742 says "The log length has exceeded the limit of 4 MB (this usually means that the test suite is raising the same exception over and over)." whereas the Raw Log from a working job https://travis-ci.org/ba-st/Willow/jobs/303028020 is 94kB. So you might start with some side-by-side diff tool to observe where these log files diverge. cheers -ben On 26 November 2017 at 03:40, Gabriel Cotelli <g.cotelli(a)gmail.com> wrote: > All the latest builds I've tried are failing in Travis with "out of > memory" errors aparently after running the tests.
