Same for Firefox. I thought the poll was closed when I visited. Now I can check it works on Chromium. I wonder how many people tried to participate before but has not the proper browser to do it and not even a clue about that. How could be this pull be made more open and accessible?

But I recommend to not have running servers/services in the saved image, but instead to save (better auto build) a new clean image with nothing open (close all windows), nothing running, just your code. And then use a startup script. Either use a run.st file which does all the work, or a class side 'MyStart startForProduction'.

Re: [Pharo-users] running Pharo8 in Digitalocean

by Sven Van Caekenberghe

Hi, Everybody is free to do whatever they want, of course. My advice would be to not use graphical tools to deploy server applications (unless as add ons afterwards, like a dashboard or management app). Use Linux (Ubuntu is the safest choice). Stick with headless (no gui) command line tools. Pharo is very good at this. The following book chapter explain things reasonably well: https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessf… Nowadays, you would use Baselines and git though. I can give you more info if you want. Feel free to ask questions.

Re: [Pharo-users] ifCurtailed prompts debug window

Also, #ifCurtailed: is supposed to fire if there's a long return that would have passed through it, while #on:do: doesn't care about long returns in the least.

Re: [Pharo-users] running Pharo8 in Digitalocean

by Sanjay Minni

Hi Eventually in a Digitalocean Ubuntu droplet, I connected from Windows 10 to a Ubuntu Graphical desktop, installed PharoLauncher and couple of images and got seaside up, installed Mongo DB and a Pharo App. pretty smooth and can share how to step by step if anybody is interested. (note: no additional software is required on Windows 10 except chrome - as SSH, Remote Desktop is inbuilt, Chrome only for its VNC app) Question: what is the best way to run and leave the Pharo App as a seaside server running. Currently I am running thru the X Desktop and if I Disconnect / logout from the remote desktop session then the pharo app may go down. also is that the most stable and resource optimised way further: is Apache recommended ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] ifCurtailed prompts debug window

by Ben Coman

With the first, you are not defining for the Error to be handled, only what to do when the stack unwinds abnormally. In the second you are defining for the Error to be handled, so it does that. cheers -ben On Sat, 16 May 2020 at 01:00, Vitor Medina Cruz <vitormcruz(a)gmail.com> wrote: > Hello, > > On Windows 10 and Pharo 8, If I do: > > [ Error signal ] ifCurtailed: [ Transcript show: 'error' ]. > > the debug window pops up, when I close, 'error' is print in the > Transcript.

Re: [Pharo-users] [ANN] What are good reasons to use Smalltalk?

by horrido

I've changed the word "developers" to "people". In a poll, it's hard to keep the question's answers brief and to the point. You don't want to be too wordy. So I have to choose my words very, very carefully so that I can be as concise as possible. I don't know how successful I am.
