4th Copper Tape Circuit

4th Copper Tape Circuit Video

Fourth try is a charm. For a while now I’ve been trying to learn how to make cheap and quick copper tape circuits as described briefly in Bunnie’s 2018 Toorcamp Keynote talk where he discusses the elements for electronics development that has so far provided him with much success. Toorcamp in 2018 happened to provide me with the copper tape used in this circuit, so I thought I’d give a shout out to my Neg9 crew and those who shared the weekend with me.

SM5 Assembler

SM5 assembler [sig]
git clone https://www.altsci.com/repo/sm5asm.git

I present the SM5 assembler. Derived from the SM5 emulator, it works well in creating new programs for the SM5 architecture. It was necessary as part of a challenge called Game Copy Protection ROM in OpenCTF 2019. It also contains a small patch to sm5emu that improves the stability and benefits the user.

Why would someone want an assembler for an architecture that is not commercially available? If an FPGA version of this architecture were created, an assembler would be handy. But until such a time, I used the assembler to create a challenge which tested the ability for users to adapt to new architectures, SM5 being an architecture that only a handful of people in the world have experience with.

A simple patch for mtpfs to close a few bugs. The severity of these bugs is unknown so the priority of fixing them depends on your risk tolerance. The most certain of the bugs occurred once during an rsync and the drawback was that the user had to reboot their phone.

BikeIM 0.5.1


May 5, 2017

On Thursday of this week (May 4, 2017) I released a mail client. It's pretty humble, but I've been using it for a decade and so it was worth it to me to iron out a handful of bugs and make it good enough for other people to use. Currently it won't be much use to you if you run Windows, Mac OSX, don't run your own mail server, or don't understand what fetchmail is*. But those things are fixable and I intend to fix them in the months to come. That means this blog post doesn't have to cater to end users, so I won't attempt to. This blog post will be about how I came to write a mail client and why it makes sense in 2017.

* The wording of that sentence was pretty bad so I'll reverse it. BikeIM-0.5 is usable to you if you run Postfix, if you run Dovecot, if you run OpenSMTPD, if you run fetchmail, if you use GnuPG, if you use Mutt, if you run Linux or *BSD, if you use Git, and understand how to report bugs.
