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...

Re: [Pharo-users] Personal wiki / information manager

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

New Memory Profiler
by Sebastian Jordan Montano Feb. 24, 2023

Feb. 24, 2023

Hello, I have been working on a new Memory Profiling for profiling object allocations. The profiler has reached a first stable version and I would like to share it with you. [ https://github.com/jordanmontt/illimani-memory-profiler | https://github.com/jordanmontt/illimani-memory-profiler ] The profiler gives some statistics, cool visualizations, like a heat-map, about the allocations and memory usage. If you want to profile the memory of some applications, this tool can help you. Also, if you have some use cases or you have some feedback please let us know because we are looking to improve the tool :) Cheers, Sebastian Jordan

Exercism's new test runner - review needed
by bajger＠gmail.com Feb. 24, 2023

Feb. 24, 2023

Hi there! \ Iâm looking for someone, who could do review of PR that implements new test runner for Exercism project that includes Pharo track. It is nice integration of using Pharo from command line, Docker (with different build args for loading correct baseline) and testing the test suite with json output (according to Exercism specific format). \ Exercism core maintainters lack knowledge of Pharo. Your help is welcome! PR here: https://github.com/exercism/pharo-smalltalk/pull/563 Related Docker part (already reviewed): https://github.com/exercism/pharo-smalltalk-test-runner/pull/16 Cheers, David

UK Smalltalk User Group Meeting - 22 February 2023
by Giovanni Corriga Feb. 14, 2023

Feb. 14, 2023

WebAssembly (WASM - https://wikiwand.com/en/Webassembly ) is an instruction format for portable high-performance code, run by a stack-based virtual machine. To Smalltalkers, this sounds very familiar. WASM is supported by the three most popular web browsers, and by other host platforms as well. Perhaps we can translate certain Smalltalk compiled methods to WASM, augmenting our support for physical processors and for livecoding the Web. For our February meeting, Craig Latta will describe his initial experiments, using the Epigram compilation framework ( https://thiscontext.com/epigram ). Craig Latta ( https://thiscontext.com/ ) is a research computer scientist in Berkeley and Amsterdam, with interests including livecoding, music performance, and interactive visualization. The discovery of a mysteriously-placed copy of the Blue Book at university led to stints at several exploratory labs, and a pursuit of improvisation wherever code is found. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/291365015/ ) to receive the meeting details.
