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.Read more »

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.Read more »

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.Read more »

It took quite a few months to get the time to work on this blog. I had AltSci Cell and AltSci Blog updated to the new blog system back in November. I ported most of AltSci Concepts to the new blog system a few months ago, but I didn't want to convert it until I had comment working. You can see there are no comments at the bottom of this page because I'm not ready to backport the comments to AltSci Cell yet. But if you go to any of the posts on AltSci Concepts you'll be able to post your comment.
In all the years of AltSci, only a handful of people have commented. The main purpose has been to collect a large corpus of spam (389245 spam comments from 67085 unique IPs, 9683389 csrf spam attempts rejected) which I've had to filter at times. But the opportunity to post responses is a valuable part of the Internet. That's probably why sites like Hacker News and Reddit are so valuable: they let you comment on important topics where the comments are disabled or too toxic to post in. That doesn't mean that these sites are infallible. In fact, that's a lot of the controversy in any open forum -- people post in a thread that is going to stay linked to that website for a long time and time increases a search engine rankings. When should the post be deleted? When should the admins leave it alone? These problems are not trivial to solve. If you think they are... please create a thread to discuss this post and e-mail me a link.Read more »
