EXIF / JPEG metadata

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

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

Pharo 6.0 and 6.1 64 bit freeze on MacMini
by Ted F.A.van Gaalen Jan. 27, 2020

Jan. 27, 2020

Hi, I reverted to 5.0 because Pharo 6.0 and 6.1 64 bit hangs on my Mac Mini with UDH 4K screen (may that has to do with?) with its maiden image (at first start after download when: I resize or go to full screen. Maybe VM problem? my mac Mini metrics: Hardware Overview: Model Name: Mac mini Model Identifier: Macmini6,2 Processor Name: Intel Core i7 Processor Speed: 2,6 GHz Number of Processors: 1 Total Number of Cores: 4 L2 Cache (per Core): 256 KB L3 Cache: 6 MB Memory: 4 GB Boot ROM Version: MM61.0106.B1F SMC Version (system): 2.8f0 maybe this problem was already reported, but could find it. Kind Regards TedvG

It seems the > only questions have been: 1) how to do them *right*, The default position would be leveraging someone else's experience, so this begs the question, what is wrong in namespace implementations in VW, Gemstone, Squeak (as our immediate neighbours, then plus Dolphin, SmalltalkX, other languages) Are there been any research papers around comparing these? I found the "Pharo on Gemstone VM" talk impressive. The "develop on Pharo deploy on Gemstone" philosophy seems like a nice synergy for Pharo's commercial future. So a naive approach would be to do namespaces just like Gemstone. Maybe its not the best, but would it be "good enough" -- perfection being the enemy of done and all that jazz. cheers -ben > and 2) where they fall on the endless prioritized todo list >

Parsing in VW
by Steffen MÃ¤rcker Dec. 3, 2019

Dec. 3, 2019

Dear all, I have two questions regarding parsing frameworks. 1) Do you have any insights on the performance of SmaCC VS Xtreams Parsing VS PetitParser? 2) Has anybody started to port PetitParser 2 from Pharo to VW? Is it worth the effort? Sorry for cross-posting, I thought this might interest both communities. Cheers, Steffen

Microsoft COM

Hi Pablo, At work I managed to remote control Internet Explorer with Excel VBA like this... [1] http://www.automateexcel.com/vba/automate-internet-explorer and went looking for how similar might be achieved from Pharo. IIUC I discovered this would be done via Microsoft's Component Object Model, and then I bumped into your repo... [2] https://github.com/tesonep/pharo-com Could you advise the status and your plans for this? Since I see its only a few months old I've probably stumbled onto it prematurely, but I see no documentation or tests to discover how to use it. So I'll curious whether it makes something like [1] possible? And could you show how that would be done? cheers -ben P.S. For context, at work I automated IE since the intranet document management system (OpenText) does authentication via a javascript function in the browser, which doesn't compute with Microsoft's MSXML.DOMDocument component. So I use IE to do the authentication and grab the raw XML from IE to then stuff it into MSXML.DOMDocument from which I pull the data I need. But I'd love to do it with Pharo instead (if I can get IT to white list it) cheers -ben

Richard Kenneth Eng is NOT Mr. Smalltalk
by Michael Zeder April 12, 2019

April 12, 2019

Dear community, I am a silent follower of this list. Now, I feel urged to speak up not on a technical, but a community matter. Every village deserves it's fool. And a wise man does not feed the troll (i did, and doing it right now, sorry). But if this fool is about to take over a considerable amount of public control, the community has to stand up against it. So, I put this to you: I frequently research on Smalltalk-related topics (computer scientist, try to devote time to open source dev next to my small enterprise). And more and more, I notice that Google search results show very much on top of the result list contributions by a self-appointed "Mr. Smalltalk" aka R.K.Eng. who excels at SEO and flooding social media. While self-initiatives are a thriving force for open communities, in this case: * one individual is hoging credit and applause, without ever having commited a single line of code, putting himself into focus (without having any profound knowledge; to the contrary: he shows a deep ignorance towards "our" and other languages, throwing around dubious advertisment slogans), * ...is throwing around with wrong claims (pulling off any potentially interested developer), * ...is starting pointless flame wars against other programming languages (again: detrimental to our community) * ...is doing SEO to make Google show his own results before FOSS community or sciences pages. * ...is getting traction (and money) for his own ends (publicity for the self-appointed "Mr. Smalltalk") * ...denies community leadership by merit (Pharo core developers do know, what they have created and where they want to go in the future, and which audience we should target, they don't need a clueless person telling them to "get into TIOBE index", just for example) * is claiming credit for the work, others have done, fostering his own publicity (not the interests of Pharo/VisualWorks etc). Here is the Medium thread that made me write this mail to you all. https://medium.com/@michael.z3d3r/who-is-this-self-appointed-mr-9ad9a18676eb https://medium.com/@richardeng/even-people-who-understand-prototypal-inheri… the bottom line of our tedious flame war in a screenshot: PS: a side note on Javascript (with lower S). wether you love or hate this quirky lovechild of Lisp and Self/Smalltalk, telling JS developers they are stupid and that they should abandon powerful Vue.js, for example, in favor of Amber Smalltalk [cudos to Amber devs! great thing!]) is utterly stupid! Every professional Javascript developer, who is trying Smalltalk the first time, because he/she has read in a post of "Mr. Smalltalk", that it is better, will instantly dismiss Smalltalk and be disappointed. I love Smalltalk (certainly more than JS), but it is detrimental, to throw around with these wrong claims (which in the end are only a self-serving, ego-centric, attention-greedy campaign to promote "Mr. Smalltalk" himself, a total newbie, who claims credit for the work of others). My suggestion: This community is open and inclusive. But we should clarify, that if a single individual repeatedly goes against those, who do the actual work, claims credits, insults people, then this person is not fit to be part of this community. It sheds a very bad light onto us. --> If R.K. Eng cannot respect community structure and decisions, we should exclude him officially and publicly take distance from this person. Thank you for your attention. Michael Zeder

why is asDictonary a class method
by Roelof Wobben March 31, 2019

March 31, 2019

Hello, Im busy with a new challenge from exercism. Where I have to keep track of a robot , where it facing and on that coordinate the robot is. so I made this function what the test wanted createDirection: aString position: aCollection Â Â Â self robot: (Robot directionLooking: aString) yourself. Â Â Â ^ self robot asDictonary I can see that on the first part a new robot is made with the right data. but the test wants the data back as a Dictonary that is why I made the self robot asDictonary line but to my suprise the compiler wants it be a class method where I expect it to be a instance method. Can someone explain to my why this is ? Roelof

How to generically find methods in class hierarchies? (Aka narrow spotter?)
by Tim Mackinnon March 31, 2019

March 31, 2019

Iâm wondering if there are better ways of finding things that I am missing. In another thread I was asking about how to wrap the lookup of an item at an index in a collection. I had browsed the collection hierarchy and not seen anything (I kept coming back to the fact that I dont find the protocol categories very helpful, particularly in the collection hierarchy). I had also used spotter - and to explain - if you type âwrapâ into spotter there are 400 methods that come up, and when you scroll down them, after about 100 the list starts to go blank (bug?). Spotter seems like the key however, but Iâm wondering if there is a way to search for âwrapâ methods in a hierarchy (limit it, and not search the full image)? I tried typing Collection, diving in and typing wrap - but that doesnât work. However I thought I had read that there was a way to search in a hierarchy - but I can seem to work it out? (Also - while the show inherited methods in Calypso is useful - I find itâs not great when you have half a concept in mind as depending on prefixes and some of the less common naming of things, it can be hard to find stuff when itâs alphabetical and not filtered. So is there a trick Iâm missing? Tim Ps - Peter spotter the method I was after was called atWrap:, so it doesnât begging with w, and hence I missed it. Sent from my iPhone
