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

https://medium.com/@svenvc/rediscovering-the-ux-of-the-legendary-hp-35-scien...

<Article-Announcement-Screenshot.png>

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.

Sven

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

That is one of my main goals.

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

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

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.

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.

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.

Thank you, Esteban, I am glad you like it. Thanks for the medium.com recommendation too !

Best regards,

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

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

Apparently it already got posted on YC News

so it needs votes and comments to survive.

Let's try again - it is hard to get up the rankings, both votes & comments help - thanks.

Great article Sven!

Thank you, Geert.

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: http://smallworks.eu/web/blog/2014-05-01-dark-theme-for-pharo HTH, Sven

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.

fantastic piece of work Sven, thanks for doing that for the community

Is now on Reddit too: http://www.reddit.com/r/programming/comments/293is3/rediscovering_the_ux_of_...

Vote up guys!

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.

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

You're welcome.

Thanks for sharing, FV

p.s.: I used one HP-35 at school from my father. I love the RPN method when I understood it :-)

You are actually the first real person that I heard of that used one ! Cool.

I got it from the "computation" bussines of my grandfather. It was new on the box, together with a lot of old stuff. The problem were the batteries, I had to adapt another batteries to it.

Yeah, I believe most people put it on a power supply now.

I don't where is it now.

Too bad, it is worth a lot of money today ;-)
