Re: [Pharo-users] in-image pharo user objet ?

by CÃ©drick BÃ©ler

Of course this can be enough but this could be more objectified. A string cannot be called a model to me. For now nothing prevents from having somebody use the id of someone else. When contributing it is associated to licence so I just find the actual model a bit weak. Then, additional functionalities could be built like storing other informations, certificates, having an external personal system that could be plugged upon each new image startup. But yes the actual solution is ok. Was just thinking loud as I try to develop personal information system, this is something that could be interesting for my use case ;-) Cheers, Cedrick > Le 27 dÃ©c. 2017 Ã 21:44, Offray Vladimir Luna CÃ¡rdenas <offray.luna(a)mutabit.com> a Ã©crit : > > Hi, > > I wonder why first and last name are not good enough.

Re: [Pharo-users] image/vm mismatch on raspberry pi model 3

by Greg Lewin

(I want to try https://github.com/pharo-iot/PharoThings on the pi) - I now see there is another VM on there ... I have just tried it with better results. Matching image-VM versions does seem to be a problem with Smalltalk. ...

image/vm mismatch on raspberry pi model 3

by Greg Lewin

Hi, Having copied a viable pair of image+changes and its associated sources file to a pi 3, in the same directory as the directory from the zip file (from https://ci.inria.fr/pharo/view/RaspberryPi/job/RaspberryPi-Publish/ws/64.zip) containing the VM code for a rpi, on running ./PharoS Pharo6.1 I get the message "This interpreter (vers. 6505) cannot read image file (vers. 6521)." How does one ensure a match between VM and image+sources on raspberry pi ? I have also tried one image pair from an earlier version and get a similar message. thanks Greg

Is there a way to set form colours using a 'fuzzy' option?

by Andy Burnett

I have an image with black text, and a white background. I would like to set the white pixels to transparent. I worked out how to do this, but of course it leaves me with a white halo around the text, where the border pixels are almost white, but not quite. In googling about this, I discovered that RMagick has the idea of replacing pixels which are almost any particular colour. I didn't find anything similar in the ColorForm class. Is there a way to do this within Pharo? Cheers Andy

Re: [Pharo-users] in-image pharo user objet ?

by Offray Vladimir Luna CÃ¡rdenas

Hi, I wonder why first and last name are not good enough. I have found the model clear and privacy aware. Such image id is complemented with remote credentials in remote repositories (SmalltalkHub, GitHub, etc) and I deploy distinct images for distinct projects or releases (which is now easier with PharoLauncher), so I fail to see other use cases.

Hi Juraj. You can find new version here https://github.com/SquareBracketAssociates/Booklet-Infrastructure <https://github.com/SquareBracketAssociates/Booklet-Infrastructure>.

Denis, I tried both. Running pharoconsole makes no difference. Same result as running Pharo.exe On Dec 27, 2017 10:47, "Denis Kudriashov" <dionisiydk(a)gmail.com> wrote: Hi.
