Pretty Spikey!
1. MIT OCW
1.1. 18.02 - Multiple Variable Calculus
1.1.1. Sessions 06-08 + PS1
1.2. 8.01X+8.01L - Physics I - Classical Mechanics with Labs
1.2.1. Finished U/P Chapter 4 reading.
1.2.2. Received materials for 3 Low Voltage Power Supplies
1.3. 21G.701 Spanish
1.3.1. Finished Episode 2 'El Secreto'
1.3.2. Ordered English/Spanish Dictionary
2. CGR-101
2.1. Oscilloscope capture with manual trigger
2.2. Debugging waveform generation
3. objgraph
4. LA County index map
No changes.
5. Mill Controller #2
Old Controller #1 seems to be operational, but there are OpenGL errors with more recent X servers. Probably protocol mismatch. Not sure if Mesa3D can handle old clients on new servers.
6. WWVB Decoder
Need to re-think.
7. Santa Cruz Weather Station
Rain Gauge is still working!
8. Marble Computation
Collected materials (thin copper plate, copper PCB blanks) for prototyping.
8.1. Next Steps
8.1.1. Continue Reversible Computation Study
8.1.2. 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?
9. ca-r
Issue #33 seems to have fixed itself.
9.1. Next Step
Wait for further breakage.
10. us-index-map
10.1. 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.
11. Sun Ultra 10
Trying to see what state it is in. Fires up but no video. Need DB25M to debug over serial port.
11.1. Next steps
11.1.1. Serial debug
12. Apple iMac G4
Building userland may be a PITA due to lack of RAM. Build would often segfault.
12.1. Next steps
Not sure.
13. Davies Brothel
13.1. New case C1923172, consolidated with 15 Parties.
13.2. Next hearing 14jan2022. Still no PACER. Hearing update unavailable.
14. Peter Kim
14.1. Broadcom CSG Employee indicted for trade secret theft.
14.2. United States v. Kim (5:21-cr-00438).
14.3. Next hearing: 1/31/2022 01:30 PM
15. Linux Audio
15.1. 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.
15.1.1. Next steps
Loop analysis
15.2. CSound programming.
The FORTRAN of computer music. Getting up to speed.
15.3. Faust programming
15.3.1. 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.
16. EPICS
16.1. Next steps
16.1.1. CGR-101 SCPI interface
See above…
16.1.2. u3scpi network port testing
16.1.3. initial EPICS interface
16.1.4. u3scpi analog/digital port reconfiguration.
16.1.5. u3scpi 'DIGITIZER' subsystem.
17. 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.
17.1. Next steps
17.1.1. Validate remaining standard GPS messages
17.1.2. Investigate GPS chipset data logging
17.1.3. Investigate LoRA radio interface
18. wktcolor
18.1. Next steps
18.1.1. Explore how to get a minimal coloring
Need a specific planar graph four coloring.
19. wktplot
19.1. Next steps
Understand why -r doesn't solve the wktvor/wktdel "sliver at edge" problem. Explore biological cell Voronoi organization
20. AMDGPU
20.1. Next step
20.1.1. Reverse engineer HSAKMT programming.
21. Ninja v Make
21.1. Next Step
21.1.1. clean simple measurements
22. GMP Forth
22.1. Need to think about adding floating point support
22.2. Port to non-Linux OS
23. Swocer
Likely will suspend future efforts in favor of just using C++ directly. There's not much value in a wrapper that isn't able to leverage Ruby very much.
23.1. Most crashing addressed
Nullified 'handle' API free functions helped a lot. Still see some errors in operations.
23.2. Added outline for 'bottle' test
Added all functions believed to be needed for 'bottle' demo test. Test doesn't pass so is disabled.
23.3. Next steps
Swocer future. Check out what's needed for gears.
