Puntcon 2017 – Sunday 9th July

Conferences are fun, but don’t have ducklings. Or champagne. Many years ago the legendary Geek Punt Picnic morphed into PuntCon, the Cambridge leg of the alternative conference circuit. And after the undoubted success of our earlier ventures, we’re going to head off up river again on Sunday 9 July 2017.


In keeping with tradition there will be no talks, no presentations, no agenda and nothing to disturb the quiet delights of the river on a Sunday afternoon. But apart from that, it’s a conference and therefore probably tax-deductible.


The Official Invitation:


You are invited to Puntcon, the fourteenth great geek punt picnic, taking place on or about the River Cam on the afternoon of Sunday 9 July 2017.


Full details are here on Eventbrite. There’s a Facebook event, too, for those who want it.


Although it says there are 250 tickets that is ‘nominal’ as it’s a big river… but Eventbrite needed a number 🙂


How it Works:


As before, turn up outside the Mill public house on Mill Lane between 1200 and 1230. We will head off  between 1230 and 1300 – if you are late you can walk up river and catch us as we don’t punt very fast!  We will be heading upriver rather than along the Backs – more picnic places, fewer tourists.


Bring something to drink and something to eat. Actually, bring a lot to eat and a lot to drink – it’s thirsty work!


Punts will be booked/organised/commandeered for you so you do not need to hire one. We will take as many punts as we need [one for every six/twelve people] and head up river to a convenient picnic place on Grantchester Meadows where we will eat/drink/carouse. Those arriving late can join us there.


Anyone can punt. Anyone can be shown how to punt. But you are not expected to punt.


We normally get back to Scudamores around 1800. Those heading back to the railway station can be dropped at a bridge within walking distance.


Post punting we have the option of retiring to the pub or a restaurant and letting Sunday evening happen around us.


How Much


There is no registration fee or indeed any other cost. Bring food and drink and entertainment. Punt fare will be split between all comers – works out at fifteen quid per person. Infants are not expected to contribute.


The Invitees


Please feel free to invite other people – it’s a big river and there are lots of punts. This page is here to give us a rough idea of numbers in advance so I know how much bread to get, but there’s a Sainsburys five minutes walk away anyway…


Some idea of who’s coming is available via the facebook. Book your spot in a punt via eventbrite.


So come along — it’ll be fun.

The UK’s Digital Economy Bill – failure of an Act

It seems to be a cross-party consensus that anything called a “Digital Economy” Bill will demonstrate how out of touch with digital the authors of Government policy can be. Especially when they have an inability to say not to special interests making a narrow argument.

The current attempt tries to enhance the digital economy with adult content filtering, and then censorship, as a “digital” fix to a social problem of people getting enjoyment from looking at porn. Good luck with that, (although it’s one way for Cabinet Office to get 25 million accounts on Verify).

In the 8 months since the Digital Economy Bill was introduced, the digital world has moved on – treating broken policy intent as damage and simply engineering around it. The Bill received Royal Assent yesterday and is now and Act.

For example, the Act introduces mandatory blocking of websites which don’t implement restrictions on access. That block limits access to a domain name (so your browser can’t work out how to show you what’s on www.ParliamentPorn.uk).

Coincidentally, also yesterday, Ethereum announced the launch of their distributed ledger implementation of DNS, to go from a human readable web address to the content/IP address using the data on the ledger (or at least, bits of it), rather than asking your ISP – who is now required by law to lie to you in the UK, and already routinely would in other countries overseas.

The Act therefore incentivises the use of censorship resistant technologies by those who are most likely to have interest in looking at prohibited content… At least UK teenagers will be more engaged in the digital economy… The Bill assumed that people would use credit cards to assert their identity – because nothing could possibly go wrong with that.

Elsewhere in Ethereum

With the ethereum browser plugin giving cryptography, services, and payments, there wouldn’t be an “hard to explain” entries in your credit card history, just another single use address amongst many others, and fully protected from the state snoopers.

Ethereum contains its own currency with micropayments built in (it is the number 2 cryptocurrency behind bitcoin), and is now finalising the design of zero-knowledge proofs – so you can pay someone money, with the sender, recipient, and amount all able to be fully anonymous (which is a higher level than bitcoin, which is pseudonymous).

The systemic incentives in many ways are obvious – using internet agreements, it’s already been shown that a set of creators and contributors to a project can agree to a contract that automatically shares the proceeds in a pre-agreed and privacy preserving way – the “fair trade music industry”. Whether this project gets used or not is up to the world, but it’s possible, and possibility is what a digital economy can produce.

As a side effect of something else, the technically possible has already undermined the Digital Economy Act’s social intent.

A viewer can access something they want to, that otherwise they couldn’t, in a manner that is fully privacy preserving, and also ensure producers can get paid. You can get a trial app for your phone here (which also does secure comms using Signal based on your wallet address rather than email/phone number).

That is what a digital economy should enable, and indeed it does as a side effect… It’d just be nice if one day they did it deliberately…

Disclosure: in my day job, I was looking at (only) Part 5 of the Digital Economy Bill, which is also broken. The above is just me, just for fun.

Ps – the use of ether addresses as Signal endpoints is a rather genius idea, to build on top anything else. Although this story isn’t entirely new.
