This evening I read the iptables man page and Linux iptables Pocket Reference from cover-to-cover; my notes are here: Netfilter.
I think at this point I am ready to use iptables in anger for the first time in a long time, and the first time ever on a router.
However, before I take that on, I’m going to have a quick diversion into the following books, and then sleep, and I will do my iptables programming when I wake up tomorrow.
Things to read to learn about FPGA programming:
I’m learning more about FPGAs. Haven’t actually purchased one to play with yet though.
Here is a presentation of the work of Iain McGilchrist: The Divided Brain.
McGilchrist has written a number of books, including:
Today on IRC the BeagleV-Fire was brought to my attention. This computer system sports an FPGA and looks like just the thing to get as an entry-level system to learn about FPGA tech. These things seem to be hard to find at the moment but apparently they sell for around US$150 which is quite affordable for an entry-level system. And the manufacturer’s commitment to open hardware is encouraging. Click-through on the link to find a heap of developer resources.
Over on An Absolute Beginners Guide To Designing PCBs using Easy EDA – Make PCB From A Schematic I learned about How to Share Projects in PCBWay Community. Seems like a good service to me, haven’t used it yet but do intend to check it out.

Today: another unboxing video! This time we’re taking a look at the Sudake SDK07 and SKD08 IC clips / SMD grippers / test probes.
Originally I was going to demo these things in this video too, but the test circuit took like two hours to make, and then when I turned it on it didn’t even work, so I cancelled that and now this is just an unboxing video and not a demo. Stay tuned for the demo which I will do, just when I can find some more time.
These test clips are really great, they let you attach a probe to the foot of an integrated circuit or a surface mount device.
Be warned: there’s a bit of swearing and bad language in this video. What can I say? I’m just a passionate individual, ya know? :P

lol, I was watching Learn Electronics Repair #2 – Geforce GTX 280 GPU Graphics Card Repair Part 1 and I learned a new term: Spudger. You will have to click-through for the definition. :)
I took some time today to update the Affiliate Links page on the blog. Now there’s a table which catalogs most of the interesting equipment in my lab along with a link (or two) to where you can buy.
As part of today’s updating of my Patreon page and my YouTube branding I took new photos of the lab, you can see them over here: https://www.jj5.net/lab/
