Giving Thanks

1. MIT OCW

1.1. 18.01 - Single Variable Calculus

1.1.1. Sessions 74-76

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

Planning lab materials along with 8.02X (Electricity and Magnetism)

2. LA County index map

Various updates including county boundary. https://github.com/daniel-kelley/la-ca-6min-index

3. Mill Controller #2

Planning mill controller upgrade for 2022. Working concept is MachineKit on BeagleBoard Black. Probably will design own IO board for 5V I/O unless I can find something that's less expensive than what I can build.

4. WWVB Decoder

Prototyped Clock sync PLL. Works against clean waveforms, fails against actual waveforms. Need to think about de-noising.

5. Santa Cruz Weather Station

Rain Gauge still working.

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.

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 topomapsall.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 14jan2022. Still no PACER.

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

  1. loscil demo
  2. spectrogram loop point analysis

13.3. Faust programming

13.3.1. Next Steps

  1. GAC Patch save/restore
  2. 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.

  3. OSC control surface

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

  4. Faust/csound

    See if a faust generated unit works.

14. EPICS

14.1. Next steps

14.1.1. Started CGR-101 SCPI interface

  1. Will help test u3scpi
  2. Using flex/bison SCPI parser

    100% system commands done. Planning 'DIGITIZER' subsystem.

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

18. AMDGPU

18.1. Next step

18.1.1. Reverse engineer HSAKMT programming.

19. Ninja v Make

19.1. Next Step

19.1.1. clean simple measurements

20. GMP Forth

20.1. Need to think about adding floating point support

20.2. Port to non-Linux OS

21. Swocer

21.1. Most crashing addressed

Nullified 'handle' API free functions helped a lot. Still see some errors in operations.

21.2. Added outline for 'bottle' test

Added all functions believed to be needed for 'bottle' demo test. Test doesn't pass so is disabled.

21.3. Next steps

Swocer future. Check out what's needed for gears.
