No U PNP
Previously on Deep Space Nine, we discussed (read: I complained about) the short life and quick death of DLNA. On the way, I mentioned DLNA's dependence on UPnP as an underlying autoconfiguration protocol. Let's talk a bit more about UPnP, because it's 1) an interesting protocol, 2) widely misunderstood, and 3)…

Fixing memory leaks in popular Python libraries
I was recently able to make a minimal example that reproduced a Celery memory leak. The memory leak would happen on the main Celery worker process that’s forked to make child processes, which makes the leak especially bad. Issue #4843 has been around for 3+ years and has 140+ comments, so this one has been causing a…

Turtle visual cortex is non-retinotopic
Most of the visual cortex studies I’ve read have been about mammalian vision. But mammals are not the only organisms with cortex, or at least tissue resembling cortex. This paper explores turtle visual cortex, in an area known as dCx. This dorsal region plays the role of the turtle primary vision center — as close as…

Conway's Game of Life on FPGA
When learning a new programming language, I like having a well defined yet non-trivial problem to solve. Conway’s Game of Life (GoL) fits this definition. It has enough depth to uncover various tradeoffs. So naturally, when I picked up Chisel hardware description language (HDL), I wanted to build Game of Life in FPGA…

Why I stopped releasing EasyOS as an ISO file
Some time ago I stopped releasing EasyOS as an ISO file, from then onward as a drive image file only. This has been contentious, and I receive emails from people lamenting the demise of the ISO. So, I should post some thoughts why I made this decision. Not an exhaustive rationale, just some thoughts while I think of…

Has the lead-crime hypothesis been debunked?
A couple of months ago a new paper was released that examined the lead-crime hypothesis. Its conclusion is that there's little evidence for an association, and if there is one it's pretty small. I haven't commented on it, but not because of its negative conclusion. It's because the paper is a meta-analysis. I'm fairly…
