The public order bill is the kind of legislation you might expect to see in Russia, Iran or Egypt. Illegal protest is defined by the bill as acts causing “serious disruption to two or more individuals, or to an organisation”. Given that the Police Act redefined “serious disruption” to include noise, this means, in effect, all meaningful protest.

For locking or glueing yourself to another protester, or to the railings or any other object, you can be sentenced to 51 weeks in prison – in other words, twice the maximum sentence for common assault. Sitting in the road, or obstructing fracking machinery, pipelines and other oil and gas infrastructure, airports or printing presses (Rupert says thanks) can get you a year. For digging a tunnel as part of a protest, you can be sent down for three years.

Even more sinister are the “serious disruption prevention orders” in the bill. Anyone who has taken part in a protest in England or Wales in the previous five years, whether or not they have been convicted of an offence, can be served with a two-year order forbidding them from attending further protests. Like prisoners on probation, they may be required to report to “a particular person at a particular place at particular times on particular days”, “to remain at a particular place for particular periods” and to submit to wearing an electronic tag. They may not associate “with particular persons”, enter “particular areas” or use the internet to encourage other people to protest. If you break these terms, you face up to 51 weeks in prison. So much for “civilised” and “democratic”.

History: 20 years ago, Heather BJ Clifford and I wrote a book, Linux IP Stacks Commentary, which walked through the Linux TCP/IP stack code and commented it in detail. (Old-timers will remember the Lion's Unix Commentary, the book published by University xerographic copies on the sly. Same sort of thing.) CoriolisOpen published it. And a bit later sank into the west. Nothing has been done since, at least not by us.

Now: when I was released from my last job, I tried retirement. Wasn't for me. I started going crazy with nothing significant to do. So, going through old hard drives (that's another story), I found the original manuscript files, plus the page proof files, for that two-decade-old book. Aha! Maybe it's time for an update. But how to keep it fresh, as Torvalds continues to release new updates of the Linux kernel? Publish it on the Web. Carefully.

After four months (and three job interviews) I have the beginnings of the second edition up and available for reading. At the moment it's an updated, corrected, and expanded version of the "gray matter", the exposition portions of the first edition. In addition, I have put forth ideas for making the commentary portions easier to keep up to date, after they are initially written.

The URL for the alpha-beta version of this Web book is https://www.satchell.net/ipsta... for your reading pleasure. The companion e-mail address is up and running for you to provide feedback. There is no paywall.

Thanks to the work of Professor Donald Knuth (thank you!) on his WEB and CWEB programming languages, I have made modifications, to devise a method for integrating code from the GIT repository of the Linux kernel without making any modifications (let alone submissions) to said kernel code. The proposed method is described in the About section of the Web book. I have scaffolded the process and it works. But that's not the hard part.

The hard part is to write the commentary itself, and crib some kind of Markup language to make the commentary publishing quality. The programs I write will integrate the kernel code with the commentary verbiage into a set of Web pages. Or two slightly different sets of web pages, if I want to support a mobile-friendly version of the commentary.

Another reason for making it a web book is that I can write it and publish it as it comes out of my virtual typewriter. No hard deadlines. No waiting for the printers. And while this can save trees, that's not my intent.

The back-of-the-napkin schedule calls for me to to finish the expository text in September, start the Python coding for generating commentary pages at the same time, and start the writing the commentary on ICMP in October. By then, Linus should have version 6.0.0 of the Linux kernel released.
