Simple statistics package?
by Esteban Maringolo March 8, 2021

March 8, 2021

Hi, I need to perform simple statistical analysis over a small set of objects (~10-1000 max), basic stuff like getting the quartiles, mean, average of a certain set and perform moving averages. I'm looking for something where I can pass a collection of objects of my domain, an accessor and get the values mentioned above. I know there is PolyMath, but it seems to be oriented towards heavy number crunching and mathematical abstractions as its input. E.g. The PMHistogram works on pure numbers, so once I build it, I cannot know which of my objects fall into what group of the histogram. Does such a thing exist? Regards! Esteban A. Maringolo

Strings in Playground are read only in Pharo 9
by Markus Wedel March 1, 2021

March 1, 2021

Hi all, strings in Playground are read only in Pharo 9.0 Build 1153 so that 'hello' at: 2 put: $a; yourself ctrl+p This throws an error: âModification forbidden: âhelloâ is read-only, hence its field cannot be modified with $a which is actually a very nice error message but is this supposed to happen? The example does work in Pharo 8 without problems. Greetings Markus

Hello happy Pharoers Today we could access our building where the M1 machine is and Pablo packaged it so that you can test the first version. Pablo wrote a little blog post for you. https://thepharo.dev/2021/02/16/first-apple-m1-pharo-version/ Let us since we do not have the M1 at hand and waiting to be able to make it accessible from our build farmâ¦ but we are not responsible for it and we were waitingâ¦. But the crew was fixing other VM glitches. So we will be ready soon to focus on the Jit version.

Problem with Dictionary and Associations
by David＠totallyobjects.com Feb. 17, 2021

Feb. 17, 2021

I am using STON to objects out to disk. Up to two days ago, I was reading them in as Dictionaries and converting to objects from there. All of a sudden yesterday morning, I got an error saying that the association is only indexable with integers. Even so, I don't seem to be able to access the contents. Fistly, any ideas why this has changed and secondly, any ideas how to fix it? David Totally Objects Sent from my Huawei tablet

Hack to show timestamp and author on versions of methods
by Davide Varvello Feb. 11, 2021

Feb. 11, 2021

Hi Guys In my opinion it is really uncomfortable working without the timestamp of a specific version of a method, I read the explanation of Esteban in the previous thread (http://forum.world.st/pharo-8-method-versions-how-to-see-author-timestamp-t…) but probably it will take some time before to see a new VersionBrowser and the history based on git is not really a solution to me. So it took a day of debugging but I discovered the flow of "versions" in Pharo 8 and I added the logic of the timestamp and the author of a method. Basically I created a subclass of MessageList I named it VersionMessageList, in this way the original MessageList is preserved for other goals I can safely ignore. Now 1) You can file-in VersionMessageList.st (see below) and 2) You have to change VersionBrowser >> initializePresenters using VersionMessageList this way: VersionBrowser >> initializePresenters messageList := self instantiate: VersionMessageList . .... Be careful, it's a hack and it's working on Pharo8, I don't know if it works on Pharo9 Cheers Davide VersionMessageList.st <http://forum.world.st/file/t77843/VersionMessageList.st> -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
