Summer Weeks 1-5

Week 1

This is the end of the end of my schooling, and the beginnning of my first summer off in 5 years. What to do? How to keep from drifting into the abyss?

Monday

There is not much left to school. My thesis is practically complete (all that’s left is paperwork), so I have finished that series and began a new one: Summer. I’m not going to start looking for a job just yet, I’m going to be spending this summer doing other things first, and starting looking for (probably remote) work in the Fall.

One thing I do need to do before I check out of school is finish my final Simulation of Discreet Systems project. It’s an elevator simulator, which I find incredibly ironic since my first project in pre-engineering in high school was a tiny motorized elevator, and I never did get the software quite right for it. Now I would definitely be able to come up with the good abstraction for such a thing. I really want to do this project over the top, so I’m going to make a Pygame visualization that shows people getting on and off the elevator. This is going to be fun. I’ve got the core logic written already, I just need to get it running and then I’ll start on the display. Visualization makes debugging 100000 times easier so I’ll do that before I even really test it.

Back from long lunch break and running some errands. Now that I’m vaccinated I don’t feel compelled to absolutely minimize every trip out anymore (I’m still trying to be relatively safe though).

I think I have the elevator working, I’m going to make a pygame animation of it tomorrow. I already have the sprites drawn and the image loading code in.

Tomorrow, I need to split up my sprites, then write the rest of the animation code. I think it’ll be pretty simple, at the start of an elevator action, it’ll send a command to the animation code to linearly move from its current position to the next (or change state, like opening door and such). And the people moving is the same thing. This’ll be so cool if I get it to work. I also made all the sprites SO ugly, I drew them in Tux Paint. Making graphical stuff in Pygame is really satisfying. Oh, also I need to add sounds: ding for door open, ding for door closed, movement sound for the elevator, and increasingly loud crowd sounds as the line gets longer. And a sound for taking the stairs once I implement that.

Wednesday

I’m working on redrawing a figure for my thesis. I had implicit permission to use it for my thesis, but not in a standard publication (in this case, arXiv). So, I’m redrawing it, with some of the info removed or changed. I get to brush up on my tikZ, which is not nearly as hard as I remember is being, I guess the practice paid off.

Done with that, and a few other small changes. I need to work on my simdis assignment, besides making the animation, I also need to write the report for it which might be non-trivial.

Done for the day, I have the drawing code basics working. Tomorrow, setting the scene and animating it.

Thursday

(didn’t blog, spent all day finishing the project)

Week 2

Went backpacking over the weekend, now to get through commencement

Monday

I’m in a weird place, not quite out of the grasp of the school but not yet completely taking part in what it is that I’m doing this summer. I feel a bit lost, tired. But also I had a very exhausting weekend: I went backpacking with my friend Greg, the first backpacking I’ve done in a long time. My body is tired, and after a bit of remembering what it’s like away from the city I find it increasingly unpleasant and hostile.

Today was about cleaning up. All my stuff from backpacking and a backlog of dishes and such from preparing for the trip.

Also, I was up until 2am playing card games (a Nomic variant) with my roommates. We had a lot of fun, and I shouldn’t be so quick to attibute my current lack of mental energy to some broad societal ill before noticing that I slept restlessly on the dirt one night, and the stayed up very late the next. There’s probably a correlation there.

So in other words, I’m fine. The start of this week isn’t such that I can start my work schedule just yet, but Thursday and Friday are work days. I need to fit in some singing practice today, then drive to mom’s and I won’t have any work until Thursday. That’s so hard for me to understand, not having work to do. But I have so much work to do, with all the portfolio building I have planned and hobbies I have going. I’m going to list them:

The first 4 are things I hope to finish this month.

Friday

This hasn’t been an office work sort of week, but next week and the week after will be, so I can accompish my software-related goals. Commencement is tommorrow, I think that’s as real as it gets for being done (for now).

Whew, using that paper template was a nightmare. It broke my bibliography, mangles links so they get forwarded through a broken .gov website, and just looks pretty ugly with its line numbers and huge margins. What a pain. Not as bad as reformatting a paper in word, though, by a long shot.

I feel really anxious, like there’s something I need to do. Commencement tomorrow is stressful, but it’s more than that. Isn’t today something important? I think it’s because I haven’t had a deadline in a week I feel like I’m probably failing some class. It’s weird that this whole summer I don’t have any deadlines.

I finished the submission, and stayed on overtime to learn to use freeCAD. I have a top secret project that’s going to require it.

Week 3

Got through commencement, letting the dust settle and organizing and planning

Thursday

I haven’t been doing any desk work this week, and that’s okay. I’m shifting my goals again - I want to quit any unfinished projects I started and focus on artificial life. I think I’ve gained a deeper understanding of the nature of what makes living things alive, and I want to put my feeling of knowledge to the test by trying to implement it. Cellular automata are really the best that we’ve got, and I think they’re tenable. Ackley’s random updates is VERY clever, since it adds robustness and I think it’s the only feature required for indefinite scalability.

So, I want to throw everything else he did out the window and only focus on 2d tiling CA with random updates. There are 3 directions to go, using MFM as the starting point:

Smoother and less complex are the first to work on, since being able to evolve and diversify the cells through stored, volatile programs feels important.

Friday

Other alife programs have really simple rules and so little state that it’s almost non-extistant. For example, Lenia (which is awesome) has a 2d grid of floating point scalars.

I have a fairly elegant idea for a neural-network-like MFM-inspired alife system, but I’m worried that it might not be expressive enough and it will end up being a huge mess by the time I’m done. This is the “Smoother” system mentioned yesterday and I’m not sure I’m ready to try and make it.

The simplified stored program MFM (less complex) might be just the right thing. Each cell has program memory and data memory, and the programs just consist of bit arrarys that act like matrices for the bit vector data.

Noon:

Got the program written, need to fix a few minor issues (accidentally allocated a megabyte of data on the stack which cause instant segfault) but then it should be running and I can hack together a quick anti-gui. Lunch time.

Week 4

The first full week of Summer, and I’m finally getting some work done on improving my website. As much as I like the retro look, I think I’m going to do some style updates, while keeping my anti-spa ethos in tact.

Monday

I feel refreshed today, and I feel like working. I also feel like laying around being anxious about nothing. I guess I can do both. Part of me wants to just work and work and work but moderation is key to long term productivity (ha, produtivity…), so I’ll take a lunch break, then come back and work another two hours before signing off and doing something non-work stuff.

Oops I skipped lunch.

I’m having trouble getting my website to run locally, I set up my emacs/slime/sbcl stack locally to run it interactively. I am also learning emacs for real this time, using a video. I might be able to obtain dual user status - emacs and vim. But it’ll cost me. I think it’s worth it though - lisp interaction modes in emacs are excellent, and vim mode is clunky. I think the main thing holding me back before was lacking a full keyboard, but now I have that so it’s time to learn emacs.

Anyway I skipped lunch so I’m quitting at 2 today, I’ll be back at it tomorrow.

Epilogue

I didn’t get back at it tomorrow, I had a lot going on this week and I felt better not adding my structured work on top of it. With my project in Bloomington starting week after next, I think it’s best to leave next week (week 5) unstructured since we’ll be working in a structured way for the next month.

Week 5

This isn’t a structured (work schedule) week. However, there are a few things I’d like to get done: - website improvements - Lisp mfm - finish intro to emacs video

I also have my creative pursuits, which work better the less I structure them. I will be practicing singing at least 3 times before my lesson on Thursday, and I’d like to make some visual art this week, too

Monday

Prepared grain spawn for shitake today. I have a few fabulous golden oyster jars, some under-hydrated pink oyster jars that are slowly colonizing, and my recently innoculated lion’s mane already on the shelf. The lion’s mane has some little star-like growths of thin mycelium, I think oysters have the best, dense fluffy mycelium and all others look weak by comparison.

My sleep has really been messed up lately, but I think it’s almost restored. I took a short semi-nap today after noon and just ate a very creative lunch (broccoli stir fry with msg and special K).

I made an art! And practiced music. I watched a CGP Grey video, and someone mentioned the hexagons (the bestagons) and I realized that my Lisp MFM should be hexagonal based, and recursive named-neighbors is the most elegant way to navigate the local plane (with a mechanism to prohibit excessive wandering - special variables and 3-space hexagonal embedding here we come).

The hexagons don’t need to be in an structured array, they can just be scattered about and linked together. I guess there does need to be a 1d array from which to select them. Fuck yes, this is going to be great.

Tuesday

I’ve developed the “tying the knot” code for making my 2d/3d hexagonal linked list. I’m really glad I took linear algebra so I understand the trick for making hexagon’s 3d coordinates and 6 directions act like a 2d hexagonal grid.

I did it! I have a working system, with empty cells and a res cell. Now I need to make a renderer for it… I think the best thing to do is make it in C using SDL and have shared memory, or maybe foriegn function call from lisp. Not sure, but I’m done programming for today.

Thursday

I’m going to burn through some more of the emacs tutorial, I really want to switch to editing lisp using emacs and not using evil mode.
