Makers

I recently finished Cory Doctrow’s new novel, Makers, which I really didn’t have time to read, but between geek book club and starting it on the plane to portland I was compelled. Like his last novel, Little Brother (which is YA fiction, but everyone should read anyway), I read it as an eBook on my n810, which is a bit of an odd reading experience, but one that is growing on me (No additional mass/volume per book! Searchable! Ever-Present! Until the damn battery runs out or it breaks!)
It is a pretty fun read, but I must say I liked the first two “lighter” sections better than the third. Some observations:

* Kettlewell seems to be largely borrowed, without the transparently symbolic name, from Willam Gibson’s character Hubertus Bigend

* Suzanne Church strikes me as a sort of composite of the notable female Internet-People, particularly Ana Marie Cox but Xeni Jardin also come to mind. I also wonder if the name isn’t a slight homage to Susan Kare, who is responsible for a starting portion of the art for early iconic computer interface elements (this is a stretch, but only a little). A little googling shows there is also a fairly appropriate real Suzanne Church, which must be a little confusing right now.

* The tech in the story is not embarrassingly wrong; its all plausible and sound except for some fanciful detours near the end. This does not normally happen when engineers read fiction, so good job Cory.

* Cory has clever ideas to try, and the hackers are damn well going to implement them. I suspect many of the things that seem clever in the book (RFID tagging all your crap to make it searchable, for example) won’t actually pan out if implemented, but I’m onboard with other things, especially the mechanical-computers-as-art hobby one of the main characters engages in.

Overall, a fun light read, worth the couple hours it takes to get through. Surprisingly, I think someone who isn’t well-versed in the workings of electronics could read the whole thing without missing much, which is remarkable considering how much fun can be had by those of us who are by working out the minutia of how the nifty plot device gadgets would actually work.

The Missing Modifier Key

My usage patterns of late have lead me to the conclusion that something critical has been omitted with modifier keys. Modifier keys are those keys that alter the meaning of keypresses, things like Shift, Alt, Ctrl, Windows, Apple, Option, Command, Function… (I think that covers most common modern keyboards, there have been others). The omission is that no environment I’m aware of reserves a key for the system; applications are always able to intercept the key-presses and do inconsistent things with them (I’m looking at YOU old fashioned text editors). A key reserved for the system (or, actually, the window manager in most stacks) would be useful in a variety of ways, all derived from implementing truly uniform behaviors system-wide. I’ll call this magical key “Sys” (for System Key, its a surprisingly little-used phrase).
Modifier keys have always contentious (and well-storied) things; see oldschool cokebottle jokes and this story about the early Macintosh (near the bottom, that isn’t the one about the symbol, but it may as well be here too). As such, I’ll provide two motivating examples for the addition (or forceful re-purposing) of a modifier:
* I’ve lately found myself hitting Ctrl+T and starting typing a query, expecting a fresh firefox tab preloaded to a google search box. Unfortunately, this doesn’t work so well something other than firefox has focus. I would like to be able to set Sys+T to “Bring the most recent Firefox window to the foreground (or launch it if there isn’t one), and pass it the command to open a new tab.” This should be easily possible with normal NetWM (or even ICCCM) capable window managers, as far as I understand the specs. There just isn’t a good interface for it (AFIK).

* Switching between Ctrl+C/Ctrl+V and Ctrl+Shift+C/Ctrl+Shift+V for copy/paste when switching between applications that have the luxury of following modern conventions and a terminal emulator is distracting and error prone. “Break” and “Background” are useful and have precedence, so I don’t begrudge the behavior, but the “correct” solution would be to have Sys+C and Sys+V manipulate the clipboard (which is (usually, mostly) managed above the application level anyway) in a context-insensitive way.

I know there are ways to approximate this behavior; many media players allow you to set global shortcuts to control them (which may conflict and are usually flaky); most environments have conventions which are theoretically consistent across applications (which are often disobeyed, particularly by still-useful applications written before the standard was established). This isn’t what I’m talking about. The “system only” nature of the key shouldn’t be optional. The window manager should trap anything between press and release of the sys key, including the presses themselves (press and release are separate signals for most keys on every keyboard design I know of), and handle the event, leaving applications completely unaware.
I’ll probably try to adapt XFCE (which seems to have pretty good facilities for this in place already) to as much of my desired behavior as is easily possible, using the windows key as my Sys, when I next have time for a little project like this (ha…). It may even be possible simply by abusing the keyboard preferences, which would be another victory for good old flexible Linux.
