EXIF / JPEG metadata
by Alistair Grant Nov. 30, 2025

Nov. 30, 2025

Hi Everyone, As far as I can tell, JPEGReadWriter in Pharo 7 doesn't read (or write) the image metadata, e.g. title, keywords, exposure time, etc. Is anyone aware of a package that does? Thanks! Alistair

The System Browser has recently started showing 2 comments tabs - one is text and one is formatted pretty. That seems odd and is not wanted - has anyone else seen this? Pharo 10 stable image - windows 64 - all reloaded recently...

Seems that Pharo is a magnet for this kind of project. I've been writing one as well and using it to organize my research notes. Does anyone working on personal info mgmt tools want to talk offline? I expect we're running into some of the same issues, both conceptual and technical. Evan

Embedding FAUST in Pharo - meet the FAUST team in Lyon
by Sebastian Jordan Montano Aug. 17, 2023

Aug. 17, 2023

Here is a message from Domenico: I tried to sent an email about this to the Pharo mailing list, but I am not sure it was forwarded. so: as ESUG in Lyon this year, I was chatting with some people of the FAUST (https://faust.grame.fr/) team at GRAME (https://www.grame.fr/) about my live coding with Pharo, the music with Pharo and if we could find a way to embed the Faust compiler in Pharo (https://faustdoc.grame.fr/manual/embedding/) one of the guys of the team would like to meet me during ESUG most probably with the director scientifiche Yann Orlarey. I told him that maybe the best thing is to join us for our usual beer-after-conference, maybe on Tuesday or on Thursday. if anybody wants to participate at the informal meeting, please express a preference about the day and time :). last but not least, GRAME is now part of INRIA,( https://team.inria.fr/emeraude/) looking forward for your reply, Pharo + FAUST could be a really cool thing. p.s. they would like to listen at to my talk on Monday morning but I guess this is a question for the esug-mailing list

Hi folks! Today I found this interesting paper via Stefan Marr on the performance differences of ast vs. bytecode interpreters (for meta compilation): https://stefan-marr.de/downloads/oopsla23-larose-et-al-ast-vs-bytecode-inte… It was a really interesting read. I do not remember seeing this on the list. If it was, please apologize double posting. Cheers! Steffen
