CITIZENFOUR showing in Edinburgh

CITIZENFOUR, Laura Poitras's documentary on Edward Snowden, sold out for its two showings in Edinburgh. The movie is rated five-stars by the Guardian ("Gripping"), and four-stars by the Independent ("Extraordinary"), the Financial Times ("True-life spy thriller"), the Observer ("Utterly engrossing"), and the Telegraph ("Everybody needs to see it").

Kickstarter-like, OurScreen will arrange to show a film if enough people sign up to see it. I've scheduled a showing:

Cameo Edinburgh, 12 noon, Tuesday 2 December 2015

If 34 people sign up by Sunday 23 November, then the showing will go ahead.

Save our Universities


An open letter to my MSPs. Support and suggestions for how to carry
this forward as a campaign are solicited.

Dear Gavin Brown, Sarah Boyack, Alison Johnstone, Kezia Dugdale,
Cameron Buchanan and Neil Findlay,

I write to ask your help to preserve a secure future for Scottish
Universities.

Academics for all UK universities, including those in Scotland, have
faced falling wages and falling pensions over many years.  "The real
wages of academics have fallen by 13% since 2008, one of the largest
sustained wage cuts any profession has suffered since the Second World
War." So wrote Will Hutton in the Guardian, October 2013 [1].

In 2011, Universities UK imposed vastly reduced pensions on new
hires. Old hires who pay into the pension fund for forty years receive
a pension of one-half their final salary; new hires who do the same
receive a pension of one-half their average salary. Basing pensions on
average rather than final salary may be sensible, but to do so with no
adjustment in multiplier suggests employers are using this as an
excuse to slip in a large cut; it means new hires receive about 2/3
the benefits received by old hires. All staff also suffered other cuts
to pensions: additional caps and less good adjustment for inflation.
At the time, it was predicted that within a few years old hires would
be moved to the inferior scheme for new hires, and that is what has
now come to pass. [2]

Universities UK argue that the reductions are necessary to avoid a
deficit, but their claim has been widely criticised. Notably, a group
of prominent statisticians point out Universities UK inflated the
deficit by assuming a buoyant economy when predicting future salaries
but assuming a recession when predicting investment returns. [3]

A strong university system is one of the jewels in the crown of the
UK, and particularly for Scotland.  That excellence is a huge driver
of innovation and growth. If Scotland reduces its investment in
universities, it won't be long before we feel that loss throughout the
economy. [4,5]

Scotland has a University system second to none, and to keep it strong
we need pay and pensions that attract and retain the best minds
throughout the world.  We must have a system that is fair to both: old
hires must retain attractive conditions; new hires must have the bad
deal imposed on them in 2011 rolled back. Speaking as an old hire, I'd
settle for a small cut in pension if it meant bringing new hires onto
the same level: we must keep the system strong for the future.

The UCU has gone on strike over the issue (suspension of assessment,
which it hopes will minimise disruption for students). But UCU is
unlikely to succeed without political support.

I write to ask you, as my representative in the Scottish parliament,
will you direct the Scottish Funding Council to make fair treatment
for academics in Scottish Universities, both new hires and old, a top
priority?

Thank you for your consideration. Yours,

-- Philip Wadler

SNAPL


SNAPL will take place 3-6 May 2015 at Asilomar.
SNAPL provides a biennial venue to focus on big-picture questions, long-running research programs, and experience reports in programming languages. The ideal SNAPL paper takes one of two forms:
  • A promising idea that would benefit from discussion and feedback.
  • A paper about an ongoing research project that might not be accepted at a traditional conference.
Examples include papers that
  • lay out a research roadmap
  • summarize experiences
  • present negative results
  • discuss design alternatives
SNAPL is interested in all aspects of programming languages. The PC is broad and open-minded and receptive to interesting ideas that will provoke thought and discussion.
Interesting papers would combine the specific with the general. Submissions are limited to five pages (excluding bibliography), and must be formatted using ACM SIG style. The final papers can be up to 10 pages in length. Accepted papers will be published on an open-access site, probably arXiv CoRR.
To encourage authors to submit only their best work, each person can be an author or co-author of a single paper only. SNAPL will prefer experienced presenters and each submission must indicate on the submission site which co-author will present the paper at the conference.
SNAPL also accepts one-page abstracts. Abstracts will be reviewed lightly and all submitted abstracts will be published on the SNAPL 2015 web page. Authors of selected abstracts will be invited to give a 5-minute presentation at the gong show at the conference.
SNAPL is unaffiliated with any organization. It is a conference for the PL community organized by the PL community.

Important Dates

Submission: January 6, 2015
Decisions announced: February 20, 2015
Final versions due: March 20, 2015
Conference: May 3-6, 2015

Errata, please

This is a space where you can leave comments describing errata in any of my published papers. Please include bibliographic details of the paper, and a link to where the paper appears on my web page if you can. Thank you to Dave Della Costa for volunteering the first entry and inspiring the creation of this post, and to all who utilise this space to record and correct my errors for posterity.

The military and the referendum.


Many readers will have heard about Lord Dannat in the Telegraph arguing a vote for independence will dishonour Scotland's war dead.

Perhaps not as many will have heard that Jimmy Sinclair (the oldest surviving Desert Rat, aged 102), Colin May (Lieutenant Commander, Faslane), and sixteen others have written a letter slamming Dannat; at least, I didn't hear until this morning. "How dare he take their sacrifice in vain and try to turn it to political advantage?"

Both sides are reported by the BBC, though the headline mentions only one. (More #bbcbias?)

The case for Europe


Readers of this list will know that I don't always see eye-to-eye with Alex Salmond. Nonetheless, I think he put the case for Europe well this morning on the Today Program.
In a BBC interview just the other night, a spanish minister being
interviewed by Kirsty Wark despite being invited three or four times
refused to say that Spain would attempt to veto Scottish
membership. And the reason for that of course is that the Spanish
government have already said that in the circumstance of a consented
democratic referendum, as they put it, Spain would have nothing to say
about it.

We can go through legal opinion and expert opinion as much as we like.
I think the answer is in four figures: 1, 20, 25, and 60.

1% is the percentage of Scotland's population compared to the European Union.

20% is the percentage of the fish stocks of the entire European Union.

25% is the percentage of the renewable energy of the entire European Union offshore.

And 60% is the oil reserves that Scotland has.

Anyone who believes that a country [with these resources] is not
going to be welcome in the wider Europe doesn't understand the process
by which Europe accepts democratic results and that Scotland has a
huge amount of attractiveness to the rest of the European continent.

You can hear the original here, the relevant segment starts at around 8:00.

The British Biased Corporation

Scandalous! Nick Robinson asks Alex Salmond a question, and Salmond takes seven minutes to answer in detail.



On the evening news, Nick Robinson summarises Salmond's answer in a few seconds as 'He didn't answer'.


(Above spotted via Arc of Prosperity.)

And today, this.
I used to be a supporter of the BBC, but it's getting harder and harder to justify.

Dinna fash yersel — Scotland will dae juist fine!

One relentless lie behind 'No' is that Scotland is too wee to make it on its own, counterexamples such as Denmark, Sweden, Singapore, and Hong Kong being conveniently ignored. May this post from Thomas Widmann, a Dane residing in Scotland, help to dispel the disinformation. 
Pick a random person from somewhere on this planet. Ask them to name an alcoholic drink from Scotland, and it’s very likely they’ll reply “Whisky”. Ask them to name one from Denmark, and they’ll probably be tongue-tied. (They could answer “Gammel Dansk” or “Akvavit”, but they’re just not nearly as famous as whisky.)

Now repeat the exercise, but ask about a food item. Again, it’s likely they’ll have heard of haggis but that they’ll be struggling to name anything from Denmark.

Now try a musical instrument. Bagpipes and … sorry, cannot think of a Danish one.

A sport? Scotland has golf, of course. Denmark can perhaps claim ownership of handball, but it’s not associated with Denmark in the way that golf makes everybody think of Scotland.

A piece of clothing? Everybody knows the kilt, but I’d be very surprised if anybody can name one from Denmark.

A monster? Everybody knows what’s lurking in Loch Ness, but is there anything scary in Denmark?

The only category where Denmark perhaps wins is toys, where Lego surely is more famous than anything from Scotland (but many people don’t know Lego is from Denmark).

Denmark is also well-known for butter and bacon, of course, but these aren’t Danish in origin or strongly associated with Denmark in people’s minds.

Several famous writers and philosophers were Danish (e.g., Hans Christian Andersen and Søren Kierkegaard), but Scotland can arguably list more names of the same calibre, and the Scottish ones wrote in English, which makes them much more accessible to the outside world.

Scottish universities are also ranked better than the Danish ones in recent World rankings.

Finally, Scotland has lots of oil and wind, water and waves. Denmark has some, but not nearly as much, and most other countries have less than Denmark.

Because of all of this, I don’t worry about the details when it comes to Scottish independence. If Denmark can be one of the richest countries on the planet, of course Scotland can be one too.

Yes, there might be a few tough years while the rUK are in a huff and before everything has been sorted out. And of course there will be occasional crises in the future, like in any other country.

However, unless you subscribe to the school that Denmark and other small countries like Norway and Switzerland are complete failures because they don’t have nuclear weapons and a permanent seat on the UN’s Security Council, there’s simply no reason to assume Scotland won’t do exceptionally well as an independent country in the longer term.

So I’m not worried. Of course there are many details to sort out, but at the end of the day everything will be fine. Scotland will be a hugely successful independent country. Dinna fash yersel!

Krugman vs. Stiglitz, now with added Stiglitz

My last post quoted Joe Stiglitz, indirectly, to refute Paul Krugman's fear mongering. Now the man himself has spoken in the Sunday Herald.
As Scotland contemplates independence, some, such as Paul Krugman, have questioned the "economics".

Would Scotland, going it alone, risk a decline in standards of living or a fall in GDP? There are, to be sure, risks in any course of action: should Scotland stay in the UK, and the UK leave the EU, the downside risks are, by almost any account, significantly greater. If Scotland stays in the UK, and the UK continues in its policies which have resulted in growing inequality, even if GDP were slightly larger, the standards of living of most Scots could fall.

Cutbacks in UK public support to education and health could force Scotland to face a set of unpalatable choices - even with Scotland having considerable discretion over what it spends its money on.

But there is, in fact, little basis for any of the forms of fear-mongering that have been advanced. Krugman, for instance, suggests that there are significant economies of scale: a small economy is likely, he seems to suggest, not to do well. But an independent Scotland will still be part of Europe, and the great success of the EU is the creation of a large economic zone.

Besides, small political entities, like Sweden, Singapore, and Hong Kong have prospered, while much larger entities have not. By an order of magnitude, far more important is pursuit of the right policies.

Another example of a non-issue is the currency. There are many currency arrangements that would work. Scotland could continue using sterling - with or without England's consent.

Because the economies of England and Scotland are so similar, a common currency is likely to work far better than the euro - even without shared fiscal policy. But many small countries have managed to have a currency of their own - floating, pegged, or "managed."
