Re: [Pharo-users] min:max:

A name like this would be clearer (although much more annoying): returnAtLeast: minValue butNoMoreThan: maxValue 10 returnAtLeast: 12 butNoMoreThan: 48 Thanks, cbc On Fri, Apr 20, 2018 at 12:51 PM, Hilaire <hilaire(a)drgeo.eu> wrote: > Hi, > > Out of curiosity. > > I always found the #min:max: confusing and lost in its expressiveness. > > One should write: > > 10 min: 48 max: 12 > > to expect 12. > > but logically one (at least me) may want to express it as: > > 10 min: 12 max: 48 > > Then when reading its source code, it is even more confusing: > > min: aMin max: aMax > ^ (self min: aMin) max: aMax > > Are not the argument names inversed in their meaning, if any? > > Hilaire > > -- > Dr. Geo > http://drgeo.eu > > > >

Re: [Pharo-users] Where do we go now ?

by Benoit St-Jean

I concur with Sean's comments.Â The problem is not using names : the problem is for new users. A very quick look at what's in Pharo 7 shows the following names : Iceberg, Ombu, Calypso, Flashback, Nautilus, Renraku, Zodiac, Shift, Zinc, Hermes, Beacon, Cargo, Hermes, Opal, Shoreline, Epicea, Balloon, BlueInk, Commander, Fuel, Glamorous, Glamour, Gofer, Hiedra, Metacello, Moose, Ring, Rubric, Shout, Spec, etc... How many Pharo *users* (not regular contributors!) know what those tools/frameworks/packages do ???Â Make the test and tell us how many out of 30 names you were able to identify correctly ! Unless we *clearly* publicize/describe what those names are, there's no way in a thousand years you could tell that BlueInk is not a package dealing with fonts (that was my first guess) ! Newcomers and (developers in general) expect a few things.Â For instance, there's a gazillion UI frameworks out there and, most of the time, the name used for them is one of a famous painter.Â VisualWorks had Chagall for instance. Or you'd expect some kind of hint from the name, e.g. XStreams, ScriptManager, RefactoringBrowser. Or somethings as simple as Regex, the regex package from Bykov.Â Or Announcements from the same guy. Or names that reveals something from an etymology standpoint, e.g. TelePharo. The simple fact that someone had to create a file to describe all those names/projects/framework on GitHub tells us a lot (https://github.com/AdamSadovsky/pharo-family/blob/master/catalog.txt) ! Unless we make it *EXTRA* clear and easily searchable and obvious what those names represent, it's just more confusion for the newcomer. Do you know what Celery is?Â Probably not!Â But if I ask you the same question for RabbitMQ, ActiveMQ, MQSeries, StormMQ, SnakeMQ, IronMQ, ZeroMQ, MQTT and MSMQ, you probably figured out it's related to message queues, right?Â Well, Celery is also related to message queues...Â See? There's nothing worse or more confusing than a bad/weird/unrelated name.Â For example, the biggest company in Canada is called "Canadian Tire".Â If you think you're gonna end up in a place specialized in tires, you're off for a big surprise !!!! On the other end of the spectrum, you have something like iTunes.Â Everybody knows iTunes.Â And I guess, even if you didn't know, you can kinda easily guess it's related to music.Â Your grandma might not exactly remember the name but she'll remember "Was it xTunes? zTunes? yTunes? It was something 'tunes', to music" ! And comparing other "names" with Pharo names makes no sense.Â Nike, Hibernate, Jenkins, Docker and Oracle cannot be compared to Epicea, BlueInk, Flashback and Opal.Â They just don't have the same visibility and public exposure.Â That is hopefully a problem that will vanish as Pharo gets more and more attention and users and gets known more and more.Â But in the meantime, those names merely help us differentiate implementations of solutions, for us the *regulars*. Was it really that hard to replace the old workspace with Workspace2 or WhateverWorkspace ?Â Or even better : get rid of the old Workspace and replace it with Playground while retaining the name "Workspace" ??? Did we really need to call it Playground and confuse every new Smalltalker out there that has seen the term "Workspace" for Dolphin, Smalltalk/X, VisualAge, VisualWorks, ObjectStudio, GNU Smalltalk, Amber, PharoJS, Smalltalk MT and every other Smalltalk around *EXCEPT* Pharo? Why are we trying to complicate things when we could just make it soooooooooooooo simple? Let's make it easy for **newcomers** to get their way around and know what the named tools/frameworks do.Â Get rid of duplicate tools (do we need more than one kind of Inspector?Â Do we need 2 compilers?Â Do we need 8 Delay schedulers?Â Do we need 2 system browsers? Do we need the duo Workspace/Playground) ?Â Make these extra tools available somewhere it can be loaded from if a user *really* wants them in their image, but let's keep those OUT of the image! ----------------- BenoÃ®t St-Jean Yahoo!

Projects using Magritte meta models

by Rafael Luque

Hi all, I'm studying Magritte reading the booklet, Seaside book chapter about it, and the source code in the image. Until now the examples I've found are related with Seaside. I wonder if there are other relevant projects I could study to discover other possible uses cases of Magritte. Thank you!

min:max:

by Hilaire

Hi, Out of curiosity. I always found the #min:max: confusing and lost in its expressiveness. One should write: Â Â Â 10 min: 48 max: 12 to expect 12. but logically one (at least me) may want to express it as: Â Â Â 10 min: 12 max: 48 Then when reading its source code, it is even more confusing: min: aMin max: aMax Â Â Â ^ (self min: aMin) max: aMax Are not the argument names inversed in their meaning, if any?

#(foo bar baz) min

by Herbert VojÄÃk

Hi all! Somehow intuitively I presume the subject line to return #bar, but it fails with ByteString not knowing min:, in Pharo 6.1. Is it a bug, bug fixed in Pharo 7, or a feature? Herby

Re: [Pharo-users] Best method for connecting to an Oracle 11g database

by Aaron Blakeman

Hi, I was trying garage, but I was using the instructions for installation from here: https://guillep.github.io/DBXTalk/garage/installation.html I was able to load garage from https://github.com/pharo-rdbms, but the method described at https://guillep.github.io/DBXTalk/garage/installation.html for loading the opendbx drivers don't appear to work. I'll play around with it a bit more. Thanks!

Re: [Pharo-users] Best method for connecting to an Oracle 11g database

by Esteban A. Maringolo

At the time my company tested Pharo to access Oracle databases, the OpenDBX driver support was lousy and it was hard to make it work in Windows. Also Garage isn't tested against it. So our resolution was that Oracle isn't supported by any driver for Pharo unless you are in Windows and can use ODBC to access it (and I don't know the current ODBC driver status for recent Pharo versions).
