Back to "no rain" normal.

1. MIT OCW

1.1. 18.02 - Multiple Variable Calculus

1.1.1. Sessions 14-16, PS2

1.2. 8.01X+8.01L - Physics I - Classical Mechanics with Labs

1.2.1. Still in U/P Chapter 5 reading.

1.3. 21G.701 Spanish

1.3.1. Finished Episodes 4-6

2. CGR-101

2.1. Prefix handling

3. Mill Controller #2

Display controller motherboard dead. Looking for replacement with VGA and PS/2 connectors (may have laying around).

4. WWVB Decoder

Need to re-think.

5. Santa Cruz Weather Station

Added restart to systemd unit file. https://github.com/daniel-kelley/sczwx/pull/10

6. Marble Computation

Collected materials (thin copper plate, copper PCB blanks) for prototyping.

6.1. Next Steps

6.1.1. Continue Reversible Computation Study

6.1.2. Prototype Marble inverter

Using dual rail differential logic (left/,right/1), an inverter merely switches sides. Now thinking an over-center spring controlling a 'side gate' controlled by a pair of sense levers. Now that there's a pile of small magnets for physics experiments, maybe something that uses those?

7. ca-r

Issue #33 seems to have fixed itself.

7.1. Next Step

Wait for further breakage.

8. us-index-map

8.1. error analysis

Started an error analysis on the USGS topomaps_all.csv index file. Nothing obvious pops up, and the error reported by Maureen would be impossible to catch anyway.

9. Sun Ultra 10

Trying to see what state it is in. Fires up but no video. Need DB25M to debug over serial port.

9.1. Next steps

9.1.1. Serial debug

10. Apple iMac G4

Building userland may be a PITA due to lack of RAM. Build would often segfault.

10.1. Next steps

Not sure.

11. Davies Brothel

11.1. New case C1923172, consolidated with 15 Parties.

11.2. Next hearing 4/5/2022.

12. Peter Kim

12.1. Broadcom CSG Employee indicted for trade secret theft.

12.2. United States v. Kim (5:21-cr-00438).

12.3. Next hearing: 1/31/2022 01:30 PM

13. Linux Audio

13.1. pvanal to spectrogram

Enough of libriffr and libpvocf work to start pvoctool https://github.com/daniel-kelley/pvoctool. Have HDF5 output and text delimited output for octave. Can import PVOC data to octave spectrogram for display.

13.1.1. Next steps

Loop analysis

13.2. CSound programming.

The FORTRAN of computer music. Getting up to speed.

13.2.1. Next Steps

loscil demo
spectrogram loop point analysis

13.3. Faust programming

13.3.1. Next Steps

GAC Patch save/restore
LV2 autopatcher

Exploratory tool to generate (was pd, ecasound, now carla) patch for arbitrary LV2 plugin: hook up audio inputs to signal source, audio outputs to speakers, control inputs to control surface, etc.
OSC control surface

Some sort of GUI tool (knob/slider) to OSC messages. This may be as simple as a Faust UI program.
Faust/csound

See if a faust generated unit works.

14. EPICS

14.1. Next steps

14.1.1. CGR-101 SCPI interface

See above…

14.1.2. u3scpi network port testing

14.1.3. initial EPICS interface

14.1.4. u3scpi analog/digital port reconfiguration.

14.1.5. u3scpi 'DIGITIZER' subsystem.

15. Brini Tracker II

Maybe this can be simplified to just the GPS module in 'tracking' mode (which gets carried around), and a separate docking module to extract the data.

15.1. Next steps

15.1.1. Validate remaining standard GPS messages

15.1.2. Investigate GPS chipset data logging

15.1.3. Investigate LoRA radio interface

16. wktcolor

16.1. Next steps

16.1.1. Explore how to get a minimal coloring

Need a specific planar graph four coloring.

17. wktplot

17.1. Next steps

Understand why -r doesn't solve the wktvor/wktdel "sliver at edge" problem. Explore biological cell Voronoi organization
