J1a SwapForth #video by jamesb beckman101, demonstrating synthesizing the CPU from #Verilog with #IceStorm. Looks like an IceStick. Demonstrates programming it interactively in a tiny #Forth with only 227 words (and a filesystem!) and generating a nice stable 1MHz square wave in software, displayed on his digital oscilloscope. #J1 #hardware

The J. Craig Venter Institute has created “JCV-syn3.0”, a reduced Mycoplasma mycoides with only 473 genes in 531 kilobases, of which they know the functions of two thirds; this is simpler than the simplest known autonomous natural life, Mycoplasma genitalium, which has 525 (?) genes. Its doubling time is about 180 minutes. #genetics #syn3.0 #biology

this office supply store in Palermo supposedly has 75g/m² acid-free printer #paper in stock for $110 per ream
45 square meters of 110g/m² #paper for AR$149, which is about US$10.
Pelletized recycled high-density #polyethylene costs AR$20/kg in 25-kg bags. #materials
Also you can buy green recycled high-density #polyethylene for AR$20/kg in 25-kg bags. #materials
Black 200-μm recycled #polyethylene film for agricultural use costs AR$1288 per roll, 4m×50m, for AR$6.44/m²; weighs 22kg, so that’s AR$58/kg. Sold retail by Ferretería Pompeya. #materials
black 100-μm #polyethylene film (presumably recycled) for agricultural use costs AR$440 for a roll of 2m×100m, AR$2.20/m², even cheaper than paper. #materials
Transparent 200-μm #polyethylene film is pricier than the black, probably because it’s not recycled: AR$1289 per 2m×50m roll (AR$12.89/m²). This is also for agricultural use; it’s not especially stretchy or sticky. It would be suitable for reducing airflow around a solar heat collector, if you don’t mind replacing it every month or two. #materials
Super-mega virgin high-density #polyethylene #geomembrane of 800 μm costs AR$629 per 7 m²; it comes in 7m×100m rolls, so you can get humongous sheets of it, although you need to plastic-weld it as shown if you want to do a waterproof installation of more than 7m width. #materials
a digital thermometer with 0.1° resolution and 1.5° error with an external sensor, good from -50° to 70°, for AR$125; from a shop called “Tu Medición” that sells all kinds of measuring #instruments
