Is Pharo part of hactoberfest?

by Kasper Osterbye

I got an invitation to participate in something called hactoberfest? It is on the link: https://hacktoberfest.digitalocean.com <https://hacktoberfest.digitalocean.com/> It looks like fun, and a way to draw attention to open source software development. If Pharo (and its sub-projects) is not part of it, this link says how to participate: https://hacktoberfest.digitalocean.com/resources <https://hacktoberfest.digitalocean.com/resources> Best, Kasper

UK Smalltalk User Group Meeting - Wednesday, September 29th 2021

by Giovanni Corriga

The next meeting of the UK Smalltalk User Group will be on Wednesday, September 29th. For this month's meeting, we take a look at an example of an application written in Smalltalk. Specifically, one that fits in a cultural tradition that is as old as Smalltalk itself, if not older: that of using computers as tools to teach powerful ideas and to augment thinking. Dr. Geo ( http://drgeo.eu/ ) is an interactive geometry software with programming capabilities in Smalltalk. Dr. Geo aims to be an open, easy to study, modify and extend interactive geometry software. Ten years old kids use Dr. Geo to explore Euclidean geometric sketches; agile kids extend and program it with its embedded dynamic Pharo language and user interface. Hilaire Fernandes started the development of Dr. Geo in 1996. In 1998, he ported it to GNU/Linux at a time where no interactive geometry software existed on this system. It latter became officially a GNU application blessed by Richard Stallman. In the spirit of free software and access to source code, Dr. Geo integrated scripting and programmed figure as well as code introspection from the application itself in an interactive programming environment. Hilaire currently teaches in a junior high school in Geneva where he uses Dr. Geo to teach mathematics (geometry) and basic programming. 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/cbklbryccmbdc/ ) to receive the meeting details. Donât forget to bring your laptop and drinks!

How to run 32-bit image in 64-bit OS?

by HernÃ¡n Morales Durand

Hello, Is there any guide on how to set up an environment for running 32-bit images in 64-bit OS? I have a bunch of 32-bit Pharo images (for example Pharo7.0.4-0-32bit-ccd1f64.image) and I want to run them in a 64-bit macOS (BigSur 11.4 now). I don't use Pharo Launcher but I tried downloading the corresponding 32-bit VM with ZeroConf curl https://get.pharo.org/64/vm70 | bash And launching those images always result in the classic error: This interpreter (vers. 68021) cannot read image file (vers. 6521) Is there any Docker solution/example for this? Cheers, HernÃ¡n

ZnServer multi-tenanting

by vinref＠gmail.com

Hello I am planning some web apps, each of which at least initially will have a modest amount of traffic. Therefore it makes sense to use one image to run them all at the same time. I can do in a straightforward way from the delegate: ``` (ZnServer startOn: 1701) ``` ``` delegate: (ZnDefaultServerDelegate new ``` ``` at: '/' put: 'shop'; ``` ``` at: 'shop' put: [ :req | self serveShopPages: req ]; â¦) ``` and then: ``` #serveShopPages: aRequest ``` ``` | host | ``` ``` host := self getHostDetails: aRequest. ``` ``` â¦ ``` and ``` #getHostDetails: aRequest ``` ``` âLook in a class-side collection for cached host details.â ``` It is cumbersome though because each slot of the routing table I have to fetch the host details, but it is not too onerous. Most of the content will be static so I can cache it on the web-cache (nginx, ATS etc). Has anyone had any experience with multi-tenanting a ZnServer? It is hard to test the scaling as it depends on 1001 different things. Vince

Breakpoint in a DoIt method

by Jesus Mari Aguirre

I need to set breakpoints in a source code compiled using > aCompiledMethod := self class compiler > source: source; > noPattern: true; > context: thisContext; > requestor: self; > bindings: self bindings; > compileDoit This compiled method has noPattern so it is executed as MyClass>>DoIt: I want to set a breakpoint programmatically, so a tried: Breakpoint removeAll. > breakpointList do:[ :aBreakpointIndex | > breakpoint := Breakpoint > breakOnAST: ( aCompiledMethod ast statements at: 2 ) > inObject: MyClassInstance. > breakpoint enable]. and executing it doesn't rises Break Exception > result:= compiledMethod > valueWithReceiver: MyClassInstance > arguments:{MyClassInstance}. It seems the breakpoint is installed because if I try to see the breakpoints folder inspecting MyClassInstance, the debugger raises errorKeyNotFound: key #DoIt: not Found in method dictionary. Any ideas?

Upgrade job

by Otto Behrens

Hi, We are running a seaside app on GemStone 3.4.1 and develop in Pharo 6.1. Is there someone out there who would be interested in taking on the job of upgrading both GemStone, Pharo and Seaside to recent versions? This is in our environment, with numerous databases, testing and dev environments. It would be preferable if the person (or people) understand Monticello, Metacello and Seaside packages that work together. This would be on a contract basis until the project is complete. Please contact me directly if you are interested. Kind regards Otto Behrens
