Budapest public transport has a tram with see-through panels so people can peek into the mechanics of how the tram works. They even have signs explaining parts.

It's pretty fun. Every time I catch it I love to watch people marveling at it, kids and adults alike. 😄

@stevengharris @pja It's so nice when people remember things like that. It was a feature I was very proud of. It was, though, a source of a bug on the first Compaq, as I recall.

@Pat I saw that. I'm new to Mastodon and I know that other places may have 500 char limits and I didn't know how they would handle it, nor how I should add a CW at the right place. I'm learning... :) How is the best way to do long posts?

@pja @danb My favorite feature was to have the floppy drive light up and make noises like data was being accessed. Later we discovered Smalltalk and could pull together quick demos that felt a bit closer to reality.

This is a Toot for all you old school applications developers

Back in the day there was a system prototyping app called DBDemo (Dan Briklin’s Demo). I “discovered” it at the time we were developing new major systems for an Australian Government department. At the time we started it had not been decided whether the new system would be PC based client/server or IBM traditional 3270 terminal based - and it didn’t matter

A systems analyst sat with our “super users” and developed the system logic. The result was packaged on 3.5” fdd and distributed to regular users for thorough testing. This cycle was repeated several times until everyone was happy with the result. DBDemo allowed the various steps of the system to be completed WITOUT any coding.

A system map of screen images was produced and handed over to the system developers. All that was required was to fill in the logic stems.

The system was developed on time and under budget - a first for us!

DBDemo was a great tool!

@danb One of the (many) things I love about this verse is how it goes from saying what the chords are — “the fourth, the fifth” — to describing their emotional function — “The minor fall, the major lift.”

If he had stuck with just naming the chords, it would have been something like “the minor sixth, return to fourth” — losing all the magic of that line.

Not everybody is able to describe the details of their craft with such poetry. A thing to strive for.

@geniodiabolico Yes! That's what I meant by "the music itself is merged with the words" but, if you don't remember the song well, that probably wasn't clear enough in part 9 of my thread. Thanks!

Oops! Secret "chord", not "cord". I guess having a degree in electrical engineering goes deep.

So, maybe the line about not caring is to introduce that maybe you should care. The next line shows that there is beauty in the details of how things are developed. 10/10

But then, the music itself is merged with the words, illustrating the meaning viscerally, and it works. The teaching of the view from a craftsperson is also merged with history (David), faith (the Lord), spirituality (Hallelujah), memories of special times with family (hearing Psalms), and more. That rich combination is a unique hook to this song for me. 9/

I found this dive into the mechanics jarring because to me, as one who likes music but has no clue how to compose it, it was like a magician revealing the mundane, esoteric details of a trick in the middle of the trick itself. 8/

The song writer then acknowledges that the listener probably does not care for the details. But, like so many engrossed in their craft, the writer then goes on to explain the details in the language of the craft even if you do not want to hear it nor understand what it means. (How many times have you watched other people's eyes glaze over as you explained something you cared about?) 7/

However, the product usually is not successful and you know that likelihood while building it. When something succeeds it is a wonderful surprise. You try, often in vain, to somehow understand why it succeeded to help you and others in the future. Engineers love to explain to others how to do things, even to a fault.) 6/

(People often ask me if I knew if VisiCalc was going to be such an important product. I answer that of course I felt that way, but I have felt that way about so many other products that were nowhere near as influential. As a creator, one usually feels what you are doing is special. That is one of the things that drives you to work so hard and long on it. 5/

Here is what I hear as one who loves to create things:

The verse starts with a song writer telling a story about when King David (who tradition says wrote the Biblical Psalms, many of which were explicitly listed as songs to be song and have been popular for thousands of years) wrote something that was especially successful (pleased the Lord). He did not expect it to be the big hit it was (with reference to the baffled king). 4/

(For those that don't know me, here is where I am coming from: I am a product creator. I helped develop some arguably successful products, including the trailblazing spreadsheet in 1979, the popular software prototyping tool Dan Bricklin's Demo Program in 1985, and the early iPad ink app NoteTakerHD in 2010. Also, of course, many less successful ones.) 3/

Why is the line "…you don't really care for music…" there? And why does it go on to break a third wall and reveal some mechanics of writing a beloved song? 2/

This is an engineer's reaction to the first verse of Leonard Cohen’s Hallelujah.

Last night, while watching the documentary "Hallelujah: Leonard Cohen, A Journey, A Song" on Netflix, I kept being struck by the first verse: "Now I've heard there was a secret cord / That David played, and it pleased the Lord / But you don't really care for music, do ya? / It goes like this, the fourth, the fifth / The minor fall, the major lift / The baffled king composing Hallelujah". 1/
