Sounds like a recipe for creating documentation that gets out of sync quickly/has bugs of its own, if you ask me... For instance, in the example, it seems weird multiplicity: (1 '*') when the method returns an empty collection if contact is nil (multiplicity 0) Cheers, Henry > On 23 Feb 2016, at 11:01 , Peter UhnÃ¡k <i.uhnak(a)gmail.com> wrote: > > > Because we may have code not present and still want to load the code. > > I think it's just visual, because it's still referenced as string in the pragma itself. > For example > > Person>>contact > <DCType: Contact multiplicity: #(1 '*')> > ^ contact ifNil: [ contact := OrderedCollection new ] > > But, > (Person>>#contact) pragmas first arguments first class == ByteSymbol > > Does it fail to load otherwise? > > Peter > > On Tue, Feb 23, 2016 at 10:43 AM, Alexandre Bergel <alexandre.bergel(a)me.com <mailto:alexandre.bergel@me.com>> wrote: > Just emerging from holidays.

Old compiler does not allowed <return: Point> only <return: #Point> And I think opal should behave the same (not fixed yet) 2016-02-23 11:01 GMT+01:00 Peter UhnÃ¡k <i.uhnak(a)gmail.com>: > > Because we may have code not present and still want to load the code. > > I think it's just visual, because it's still referenced as string in the > pragma itself. > For example > > Person>>contact > <DCType: Contact multiplicity: #(1 '*')> > ^ contact ifNil: [ contact := OrderedCollection new ] > > But, > (Person>>#contact) pragmas first arguments first class == ByteSymbol > > Does it fail to load otherwise? > > Peter > > On Tue, Feb 23, 2016 at 10:43 AM, Alexandre Bergel < > alexandre.bergel(a)me.com> wrote: > >> Just emerging from holidays.

Re: [Pharo-dev] Hackathon IoT. I used Pharo.

by Ben Coman

There is real business opportunity for "Industrial" Internet of Things. Morphic (and next Block) makes Pharo would make a fantastic platform for the HMI (Human Machine Intereface) of a factory or machine. And its good reoccurring work, as engineers are *paid* to consult on troubleshooting, optimising and modifying the factory automation code as factories evolve over time. Two significant enabling technologies are... OPC (Open Platform Computing) - This is *the* integration protocol for factories. Its the most widely adopted interoperability standard for secure, reliable and platform-independent information exchange for industrial automation. * Over 500 OPC Foundation members and thousands of OPC-compliant products https://opcfoundation.org/members * Understanding OPC: Open Connectivity via Open Standards http://www.automation.com/pdf_articles/Understanding_OPC_Kepware_eBook.pdf EtherCAT - Ethernet for Control Automation Technology adds real-time and other capabilities to classic Ethernet * Endorsed by more than 3,000 companies https://www.ethercat.org/en/members.php * What are the advantages of EtherCAT over other fieldbus technologies? https://www.youtube.com/watch?v=j3j6segCpEc * High speed servo control of motors over EtherCAT - simply not possible with any other industrial comms protocol https://www.youtube.com/watch?v=CXb_m8p3Yt4 * MCUs and EtherCAT Gear Up for the Industrial Internet of Things. http://www.digikey.com/en/articles/techzone/2015/aug/mcus-and-ethercat-gear… * The *biggest* advantages is the use of standard ethernet, doing away with proprietary hardware and consequent vendor lock in. https://www.youtube.com/watch?v=klxwX_44DcM (stop watching a 5:00) And now these two technology groups are now working together... https://opcfoundation.org/news/press-releases/opc-foundation-ethercat-techn… cheers -ben On Tue, Feb 23, 2016 at 3:30 PM, stepharo <stepharo(a)free.fr> wrote: > I'm interested too because we Rmod wants to check Pharo as a IoT platform in > the future > > Le 22/2/16 15:07, philippe.back(a)highoctane.be a Ã©crit : > > LoRa stuff with sensors etc. Integrated REST apis for that in Pharo. > > I'll do a writeup on my blog. > > Lots of opportunities for Pharo in that space. > > Phil > > On Feb 22, 2016 2:49 PM, "Serge Stinckwich" <serge.stinckwich(a)gmail.com> > wrote: >> >> Great !
