i don't do much but coped with small software projects in python this week. i found a very powerful language model architecture called sgconv that is one of the leading world models atm. the current state of the model it required 20GB of ram per layer, and would not run on my old system, so i poked at optimizing the ram usage. i removed temporaries from the kernel allocation and broke the core convolution phase into tiles so the ram usage could be controlled. the work is at https://github.com/ctlllll/SGConv/pull/5 . i am daydreaming of next adding implicit dealiasing to the convolution, which further increases speed and reduces memory requirements, and i think with some tuning it could be done in such a way that the kernel construction can be removed entirely. i would likely add pushes to that pull request if i did that. i found also a parametric generator for lasercut boxes and other parts, including gear stages. this was really exciting to me because i have spent a lot of personal energy trying to begin something similar, and fought hard with my dissociated parts, and mostly lost the work. i thought i would use the hears for the rotary encoder project, and poking at adding bolts to them to clip them in some way to shafts of the cheap motors i get which don’t have a D cut. i found the the code has existing code for bolts that is disabled and the issues for enabling them was disrupted by a question and answer session with a visitor. i added imperial measurements to the bold code to be easy to use in my country, and a command line option to specify the bolt standard, and enabled the code. this work is at https://github.com/florianfesti/boxes/pull/468 . it likely has bugs since i have not tested it, which requires a lasercutter, but there is a reasonable chance that it works well enough to use. in my xloem github user i forked the repository and there is a branch with the gear bolt work. it’s not the best way to attach a gear to a shaft, and i’m curious what the best way would be, but i wanted to try it. both of these projects were quite enjoyable to me, and i’m presently holding plans to continue them, but they are recreational and not what i intended to dedicate much time to. still, i do really appreciate the experiences of, despite my issues, meeting goals I find hard and used to be skilled it. i look for those successes and want to nurture them.
