[Tutorial] Rediscovering the UX of the legendary HP-35 Scientific Pocket Calculator

Sven Van Caekenberghe-2
Hi,

I have written a new, extensive, long form, introductory article about Pharo. 

  Rediscovering the UX of the legendary HP-35 Scientific Pocket Calculator

  A tutorial on Pharo, test and specification based immersive programming



It is a bit different because

 - it is based on a non-trivial example
 - it uses a backdrop story unrelated to Pharo
 - it uses several multimedia elements
 - it is published on medium.com which is a general publishing platform

The appendix describes several ways you can get the code. I think building both a Spec and Seaside UI from the same specification as well as reusing functional tests in different contexts is cool. Anyway, I hope you enjoy it.

The code was ready for some time, but you pushed me to finally write the text, I was postponing that - so thanks for the push !

Thanks for interesting article. It will help me sink my teeth further into Pharo

Damn, it is such a long time since I saw slide rule anywhere. Gulp, I shouldn't betray my age.

It looks like you forgot to mention the S word. It first appears in the Appendix and then in a URL. Watch out for the flames and the debates.

Sven. This is outstanding.

It is not only a comprehensive tutorial, but also is good loking, with
a little touch of nostalgia for those who used a RPN calculator in the
past :)

I wish we all could produce code and documentation the way you do.
Maybe cloning you is an option.

Congratulations.

Best regards,


ps: there is a typo in the first image of "Modelling the HP-35" section.

Well, if you just saw a slide rule, then it is OK, if you used one, then that is something else ;-)

Well, that is on purpose: in the Pharo community there is a general consensus that talking about Smalltalk or Lisp scares away people. Another goal of the article is to attract new people, if such a thing is possible.

Of course, Pharo is a Smalltalk, and is based on a long tradition/lineage that we are proud of. But going forward to the future, we want no restrictions.

Anyway, a fun fact is that the HP-35 came out in 1972, which was pretty ground breaking in terms of new technology, but Smalltalk did already exist then in the form of Smalltalk-72 - something to think about.

Fixed. Yes, I think too much about models ;-)

Yes, the HP-41 was the one I was dreaming about when I was young: it was so cool - it went on several Space Shuttle missions and they used that a lot in their ads - but it was way too expensive for me as a kid.

Great article Sven!

It would be great to also add a brief explanation in the appendix how newbies can get the great looking "optional" dark theme after downloading Pharo 3. #JustAnIdea

I understand, but the article is already quite long ;-) And I don't want to be too technical.

Now, in Pharo 4, the dark theme comes included, you just have to enable it. This is the original blog post announcing the dark theme:

Thanks; like I said, this last year we seem to have this friendly competition in trying to produce the best possible documentation. Everyone's contributions, combined, will eventually make a difference, I am sure.

Thanks Sebastian, I got lots of referrals from reddit.com !

I will do a short follow up after a week or so with some statistics, because I think this is important as well.

Hi,

 

I have written a new, extensive, long form, introductory article about Pharo. 

 

  Rediscovering the UX of the legendary HP-35 Scientific Pocket Calculator

 

  A tutorial on Pharo, test and specification based immersive programming

 

 

 

It is a bit different because

 

 - it is based on a non-trivial example

 - it uses a backdrop story unrelated to Pharo

 - it uses several multimedia elements

 - it is published on medium.com which is a general publishing platform

 

The appendix describes several ways you can get the code. I think building both a Spec and Seaside UI from the same specification as well as reusing functional tests in different contexts is cool. Anyway, I hope you enjoy it.

Yeah, I am beginning to realise that being interested in historic calculators puts you in a certain age bracket ;-)
