+### Build

In my `~/.xinitrc` I have something like the following:
```sh

TODO
----
-
+- track energy usage rate
+- formalize message format and protocol
- tests (design is starting to take shape, so it is time)
- show how many Debian package updates are available
- show how many Debian package security-updates are available
- snooze time (if already alerted, when to re-alert?)
- text: subject/body
- monitor processes
+ - totals (grand and per state)
- zombies
+ - threads
- CPU hogs
- memory hogs
- memory leaks (if some process consistently grows)
+ - is select process up?
+ - log resource usage of select processes
+- monitor arbitrary HTTP endpoint availability
+ - is status within expected range?
+ - response time
+ - is responce time within acceptable range?
- report detailed status upon request (to a terminal)
- use color to indicate age of data
+- monitor logins
+ - totals (per time period)
+ - failures
+ - successes
+ - most recent
+ - success
+ - failure
+- monitor battery time remaining
+ - monitor accuracy (is percentage change rate on track to meet estimate?)
+ - adjust estimate based on observed inaccuracies in past estimates (Kalman?)
Redesign notes
--------------
intervals at runtime (which seems like a better idea than the above in-memory
DB one).

+Idea grab bag
+-------------
+
+- track devices:
+ - alert when never before seen device is plugged-in
+ - report history and trends on when and how-often each
+ device/category is plugged-in, how-long it stays plaugged-in, etc.
+- daemonize `khatus`, so we don't have to re-launch `X11` to re-launch `khatus`
+- interoperate with other khatus nodes
+ - prefix machine ID to each data source
+ (What should that ID be? Hostname? Pub key?)
+ - fetch remote data and process locally
+ - what transport to use?
+ - ssh + rsync + cache dumps per some interval?
+ - `A` can setup self penetration testing, by setting up probe of `A` on `B`
+ and fetching results from `B` to `A`
+- offline mode - quick disable all network-using subsystems (sensors, monitors, etc)
+- classify each sensor as either "local" or "remote" (what about `iwconfig`, et al?)
- store data with rrdtool
+- some kind of personal calendar thing integration
- monitor tracking numbers (17track should be easiest to get started with)
+- monitor password digests against known leaked password databases
- monitor stock prices
- monitor some item price(s) at some store(s) (Amazon, etc.)

+- vacation planning optimization
+ - I want to visit a set of places within some time period. Given the
+ current set of prices, a set of constraints (I need to stay some amount
+ of days at each, I must be in X at Y date, etc), which visiting dates for
+ each are cheapest?
- browse https://www.programmableweb.com/ for some more ideas
- GC trick: instead of actually doing GC, do a dummy run of building a status
bar at `BEGIN`, to fill-in the atimes for keys we need, then use the atimes
