A case against syntax highlighting

Anonymous
Wed 2-Jul-2014 20:05
I chanced upon this article while searching for *scientific* studies about the pros and cons of syntax highlighting. I didn't find such studies, but kudos for raising the topic! It is true that Linus does not back up his claims by experiments, like a speed reading test. But, amusingly, his most vocal critics here seem unaware that they too must back up their claims with figures instead of gut feelings. I think this topic deserves a methodical study. I'd surely love to see figures how much syntax highlighting helps or distracts depending on the circumstances.

Ha, I just found a scientific study about this:

http://www.ppig.org/papers/18th-hakala.pdf.

Here is a key part of the conclusion (page 51):

"A suprising finding was that the control scheme, black text on white background, resulted in the same overall search performance as the other coloring schemes.
...
The participants' overall comments on color usage were positive and they reported of perceived performance improvement. However, the results of the experiment do not support his intuition."

This makes the "this blog article is bullshit" comments above look quite amusing indeed.

Here's a good one:

I think it's a good one, because it was actually easier than #26! :)

> Writing to a TTY which is stopped due to flow control, ...... will block your process
I can't understand? The process will not blocked when TTY is stopped by flow control(ctrl+S), the foreground process will continue running. The only difference is I can't see the display until I type ctrl+Q again.

You're right Nyu... and this running process may be blocked when the TTY kernel buffer is full of non-displayed characters, if it outputs too much on stdout/stderr.
I guess the author has taken a shortcut when writing this, as the flow control stop is often used to block a too verbose process and to be able to read few lines before let it go on again.

En annan nackdel med syntaxfärger är att man skriver kod på ett mycket mer rörigt sätt just på grund av att den är lättare att läsa med färger. Utan färgerna (om man öppnar filen med `less`) blir den mer svårläst. Skriver man utan färger från början så blir man tvungen att arrangera koden på ett snyggare sätt, t.ex. genom att indentera variabelnamn, och den blir då lättläst både med färger och i svartvitt.

As one of the non-coder types I'd like a rendered MP3 of this great tune too.

Hi!
I'm struggling with RS485 communication:
Is it possible to configure a tty to automatically raise the RTS line before sending and lower the RTS line after sending?
Thank you for your input,
Helmut

It true that debugging do improve the understanding of the myth underlying the technologies, especially when debugging others's code in programming.

Very nice. Good of you to not attempt to debunk Kernighan but leverage his quote!

the VT100 was not a colour terminal as the text suggests, though.

Tracking down the ^Z problem in vim

I never run into this problem because I usually :!make. Is it necessary to really stop vim in order to do make?
