Once we have this "official" logo, how do you expect it to be used? Do you expect organisations to use it in their literature as part of their branding identity? Should it get equal weighting as their corporate identity? Will all these commercial entities feel the logo strengthens their position in solidarity, or dilutes their position. You know that some our community differentiate Pharo from Smalltalk. Also an important question to determine early on, how will copyright and trademark rights of the logo be controlled? cheers -ben Of course, my stylized hot air balloon would be Logo Candidate Entry #1. > > If you think this is a good idea, I'll start organizing it.

Hi Phil, I don't like the diamond in the back, nor the colors (looks old). Also the square brackets and vertical bar are not horizontally centered. I still like the concept though.

I got a shot at this and this gives the following. What we should do: - ensure the [|] shape has the gold ratio (so it is naturally attractive). - make sure the square is positioned so that the golden ratio is also all over the place. Color wise, I went for blue because Smalltalk has a natural elegance and goes for no crap. Phil On Wed, May 3, 2017 at 12:49 PM, horrido <horrido.hobbies(a)gmail.com> wrote: > Esteban A.

I still like it but it can be done better. *[|]* seems to be a popular choice. I got two votes for this at LinkedIn. It looks rather plain to me, though. It lacks sizzle. Maybe the best way to settle this is to have a Smalltalk logo competition. People can submit their logo designs and a panel of judges can decide on the best one.

Hi Cyril, I want to try to write such a detector. I'll get back to you. Any chance you could give me (part of) a file that causes you trouble (one that is legal latin1, yet does not fail utf-8 while doing it wrong in utf-8) ?

How to detect encoding of a file

by Cyril Ferlicot D.

Hello, We have a problem using Moose because we have files which we don't know the encoding. Currently we have this implementation to get the content of a file: completeText self fileReference exists ifFalse: [ ^ '' ]. ^ self fileReference readStreamDo: [ :s | [ s contents ] on: Error do: [ [ s converter: Latin1TextConverter new; contents ] on: Error do: [ '' ] ] ] But, we have a problem because we have currently some files at Synectique in ISO-8859-1. The problem is that #contents is able to read some of the files without throwing an error, but the content is not right because it is not the good encoding. Thus I wonder if it is possible to get the Encoding of a FileReference in Pharo to be able to read the file with the right encoding? Something like the bash command `file -I myFile.txt`. -- Cyril Ferlicot https://ferlicot.fr http://www.synectique.eu 2 rue Jacques PrÃ©vert 01, 59650 Villeneuve d'ascq France
