Re: [9fans] Musings on Interfaces

[Bakul Shah <bakul@bitblocks.com>]

Yesterday someone asked me how come the two 24" monitors on my desk @ work were turned off and I was using the laptop exclusively. Apart from having to be in meetings, the main reason is that acme on a hires "retina" display is more than good enough for programming. I still switch to vi for certain things (mainly because vi has become "transparent"  through decades of use). And occasionally notepad for Unicode requiring complex text layout. 3-4 column layout in acme works about right for me.

I’ve been working 10 to 12 hour days, six days a week lately. I just wanted to change things a bit. Nothing against acme. I’ve been using it for many years and it is a great tool.

Many of the original folks also use acme. I had did a poll years ago but can’t seem to find the results. As did I for many years, even after acme make its appearance. I had gotten a version of it working on my Unix using an Teletype 630 terminal, downloading the samterm and all. It was the main Plan 9 editor during my very brief tenure at Bell Labs in 1990. Acme came after I left with the arrival of Phil Winterbottom and his Alef language. The window manager was 8 1/2, which is like rio(1) without the bumpers one can use to move and resize the window.

I kept trying to use chording in sam and realized that part of the problem was that I could still use it in rio. So, I added a shell variable that turned that feature of rio off. After that subconscious chording stopped.

And that difference has an affect on the way one used the system. When I use acme, I mostly stay in acme, using the win program for my shell access. It becomes a kind of integrated environment. With sam, I seem to use tools like sed and awk in the rio windows, like sed and awk more than when I was using acme. I had a similar thing happen when in the 1980’s I dropped vi for ed. I used ed until the 1990’s when I was able to switch to sam full time.

The command language in acme using the Edit command is the same, but somehow it feels different. There is something to be said for the convenience of the command windows in sam.

Our tools should be, for the most part, transparent. It took about a week to switch back to sam from acme. That time is certainly a function of how much I used sam in the past.

It’s a very personal thing but for someone who first used 6th Edition Unix, ed and the old shell, and used all the versions of Unix that followed, these tools, both acme and sam, rio and 8 1/2, are an improvement to all that proceeded them and followed them.
