= IFIP Working Group 2.11, Twenty-fourth Meeting =

== December 3rd (Tues) - 6th (Fri) in Edinburgh, Scotland, UK ==

The meeting will be hosted by [https://www.denotational.co.uk/ Ohad Kammar], who will write in the first person in the remainder. If you want to know anything, please email me. This page is not yet finished, I'll try to add the missing information as soon as possible.

The meeting will last 3.5 days; the first three days (Tues-Thur) will
be full-day whereas the last day (Fri) will be a half-day session.

=== Venue ===

[https://www.ed.ac.uk/timetabling-examinations/timetabling/room-bookings/bookable-rooms3/room/0401_01_1.07 Althaus-Reid Room, 1.07] ([http://exhibition.div.ed.ac.uk/rooms-renamed-in-honour-of-two-inspirational-female-theologians/ named after the theologian Marcella Althaus-Reid])

New College 
School of Divinity 
The University of Edinburgh 
Central Campus 
1 Mound Place 
Edinburgh EH1 2LU

This is unfortunately '''not''' the School of Informatics, which is about 15 minutes walk south from this venue.

I'll include a Google map soon with the venue, and populate it with other
relevant locations closer to the event.

==== WiFi Access ====

If you have eduroam credentials, you may use them to access the
eduroam network while at Edinburgh.

I'm looking into setting up guest accounts for participants without
eduroam credentials, and will put the information here closer to the date.

==== Workspace ====

A quiet area for shared use is available in the [https://www.ed.ac.uk/timetabling-examinations/timetabling/room-bookings/bookable-rooms3/room/0401_01_1.09 Porteous Room 1.09]
(you can read more about it
[https://exhibition.div.ed.ac.uk/porteous%E2%80%AFroom/ here]) on the
same floor as the main room.

== Travel ==

=== Travel to Edinburgh ===

==== Air ====

[https://www.edinburghairport.com/ Edinburgh Airport] is located
approximately 8 miles away from the city centre.

The [https://edinburghtrams.com/ Edinburgh tram] runs from the
airport every 7 minutes, the last tram from the airport leaves after
22:30 (see tram webpage).

The [https://airlink100.co.uk/ Airlink bus] (service 100) runs
between the airport and the city centre, reaching Waverley Bridge
railway station in 25 minutes. The route to and from the airport runs
24 hours a day every 10 minutes approximately during the day.

Most advance hire taxi companies will offer an airport pick-up
service. [https://www.taxis-edinburgh.co.uk/ Here's one], but any will
do. There's also a taxi hailing stand at the airport, follow the signs.

You can also fly into another main UK city and continue to Edinburgh by [[#Train|train]].

==== Train ====

Edinburgh is well-connected to most other main UK cities. There are a
few faster trains from London (about 4h25min) every day. You can use [https://www.nationalrail.co.uk/ National Rail] to plan your trip and link you to the appropriate provider.

I have enjoyed taking the Eurostar from the main continent to London. There is also the [https://www.sleeper.scot/ Caledonian Sleeper] that can get you to Edinburgh or London by 7am very slowly overnight.

=== Travel around Edinburgh ===

Edinburgh is somewhat hilly and the venue is located [https://upload.wikimedia.org/wikipedia/commons/f/ff/The_Mound%2C_Edinburgh%2C_18_September_2014.jpg up a slope].
If that is not a problem, then Edinburgh is quite walkable.

Public transportation is available. Check out [https://transportforedinburgh.com/ Transport for Edinburgh] for all the details.

* Buses. [https://www.lothianbuses.com/ Lothian buses] operates many of the relevant buses. You can pay contactless with a card or app and there's a capped pay program ('TapTapCap'). Here's the [https://www.lothianbuses.com/wp-content/uploads/2024/09/Network_Map_240908.pdf map], but I usually use Google maps for directions.

* Taxis. You can usually just hail a black cab from anywhere in the centre, see their [https://www.taxis-edinburgh.co.uk/ webpage] for advance bookings. Your favourite search engine will provide other taxi companies.

* Tram. The [https://edinburghtrams.com/ Edinburgh tram] stops fairly close to the venue, so can be an easy way to the venue.

* Uber operates in Edinburgh.

== Accommodation ==

The venue is located quite centrally, with many hotels nearby. I'll
filter out some 3-star and 4-star suggestions nearby soon, but you'll
probably find somewhere charming by your own (just watch out for scams).
The tram and buses make it easy to also stay somewhere away from the
centre and commute in if you prefer.

== Weather ==

Edinburgh has temperate (and temperamental) climate, and in December it will likely be close to zero degrees centrigade, typically above. It will be windy, and potentially rainy, so make sure you dress appropriately. Locals wear waterproof/resistant clothes. Umbrellas tend to be rather useless due to the wind, one typically recognises the tourists by their futile struggles to turn inside-out umbrellas
while getting soaked.

The days are quite short in December, and you might be able to catch
the sunrise heading into the venue in the morning. I recommend
avoiding missing most of the daylight completely, e.g., make sure you go
for a short walk outside during the lunch break.

== Tourism ==

Edinburgh offers many tourist attractions and museums, and many are located centrally and close to the venue. Entrance to museums and galleries is free. Entrance to some exhibitions in the museum or gallery will require buying a separate ticket.

The meeting takes place just after [https://www.visitscotland.com/things-to-do/events/st-andrews-day Saint Andrew's Day] weekend, and Monday will be a public holiday in Scotland.
That should not affect travel, although the airport and railway might be busier than usual.

[https://www.historicenvironment.scot/about-us/news/st-andrews-day-ticket-giveaway/ Historic Environment Scotland] offer free tickets to visit some Historic Scotland attractions on Saint Andrew's day, such as the Edinburgh Castle. Registration for [https://www.historicenvironment.scot/ticket-giveaway/ free tourism tickets] opens Tuesday 12 November 10am UK time until Thursday 28 November.

If you go to the Castle, try to get there before 1pm to see them fire the Cannon.

Very near the venue is Scott Monument which you can climb, for a fee,
during the day for a stunning view. There will be a German Christmas
Market nearby I believe.

There are several hills within the city and you can easily climb up. The easiest (and closest to the venue) is [https://ewh.org.uk/calton-hill/ Carlton Hill] and has a road and steps leading all the way up.

[https://www.geolsoc.org.uk/GeositesArthursSeat Arthur's Seat and the Salisbury Crags] are most visible from the centre. It takes about 1.5 hours roundtrip to get to the top. The grass can be slippery after a rain, and people can slip to their death, so wear good shoes and only climb during the day.

You can sometimes take a daytrip on a guided tour to the highlands or a whisky distillery. If you have the time, I recommend spending a few days in the former, and maybe visiting some of the latter.

I'll try to add more stuff here, especially if people send me recommendations or ask questions.

== Registration ==

Working on it, I'll put up more details soon.

== Talks ==

See below for the schedule (but note that the actual scheduling of talks will not be available until the meeting starts). Members: please add yourself and your topic, alphabetically ordered by surname:

* Edwin Brady [[WG211/M24Brady | "Normalisation by Compilation": Typechecking Dependent Types via the Scheme Runtime ]]
* Tiark Rompf [[WG211/M24Rompf | Rhyme: A Data-Centric Multi-Paradigm Query Language ]]

We will follow our usual format of interactive talks with an active audience, using a chess clock for timing, as follows. For each talk the speaker and the audience each get at most 25 minutes. The audience does not have to wait until the end of a talk to ask questions; interaction and discussion is encouraged. (But experience from previous meetings shows that it is useful to let the speaker at least finish the introduction before interrupting.) To ensure fairness, administration of the time used by each party is done using a chess clock. Operation of the clock rotates among participants. Both speaker and audience are expected to contribute to make talks and discussions engaging, interesting, and useful. Therefore, we observe a policy of no use of electronic devices during talks (other than the device the speaker uses to present slides). Bring paper and pen for making notes.

== Breadth-First Traversal Via Staging ==

Jeremy Gibbons (joint work with Oisin Kidney, Tom Schrijvers, Nick Wu)

An effectful traversal of a data structure iterates over every element, in some predetermined order, collecting computational effects in the process. Depth-first effectful traversal of a tree is straightforward to define compositionally, since it precisely follows the shape of the data. What about breadth-first effectful traversal? An indirect route is to factorize the data structure into shape and contents, traverse the contents, then rebuild the data structure with new contents. We show that this can instead be done directly using staging, expressed using a construction related to free applicative functors. The staged traversals lend themselves well to fusion; we prove a novel fusion rule for effectful traversals, and use it in another solution to Bird's "repmin" problem.

=IFIP Working Group 2.11, Twenty-second Meeting=

== April 3rd–4th 2023 in Delft, The Netherlands ==

The meeting will be hosted by [https://pdmosses.github.io Peter Mosses].

The meeting will last 2 full days; it will be followed by [https://symposium.eelcovisser.org EVCS: Eelco Visser Commemorative Symposium] on April 5th.

=== EVCS: Eelco Visser Commemorative Symposium ===

A commemorative symposium for [https://www.tudelft.nl/en/2022/eemcs/in-memoriam-eelco-visser-1966-2022 Eelco Visser] is to be held on April 5th 2023: the first anniversary of his untimely passing. It will bring together colleagues from various communities, with presentations of papers on topics related to his research and his other academic activities.

For further details, see [https://symposium.eelcovisser.org the symposium website].

=== Venue ===

The Twenty-second meeting of WG 2.11 takes place on the campus of
[https://www.tudelft.nl/en/ Delft University of Technology] (TU Delft)
in
[https://map.tudelftcampus.nl '''Building 36''']
located at Mekelweg 4, 2628 CD, Delft.

A co-located [https://languagedesign.org/meetings/Delft2023.html meeting of WG 2.16] takes place on the same days.

=== Travel ===

==== Getting to Delft ====

The city of Delft is located about halfway between ''The Hague (Den Haag)'' and ''Rotterdam''.

Delft has two '''train stations''':
* The main one '''Delft''' (“Delft Station” on travel planners) has frequent Intercity (IC) connections from Amsterdam, The Hague, Rotterdam, and other Dutch cities.
* The smaller '''Delft Campus''' station has only Sprinter connections – Intercity trains do ''not'' stop there.

You can reach Amsterdam and Rotterdam by '''high-speed trains''' from:
* Germany and Switzerland (''ICE International'' via Utrecht),
* Belgium and France (''Thalys''),
* England (''Eurostar'').

The '''closest airports''' to Delft are '''Schiphol Airport''' (AMS) and '''Rotterdam-The Hague Airport''' (RTM).
* Schiphol Airport has train connections to Delft (usually every 15 minutes, and taking about 40 minutes). Some connections are direct, for others you need to change at Leiden.
* Rotterdam-The Hague Airport has bus connections to Rotterdam.

To determine your route and travel time to (or in) Delft you can use [https://www.9292ov.nl '''9292'''].

For information about car parking, see the [https://www.tudelftcampus.nl/accessibility/ Contact and Accessibility] section on the TU Delft website.

==== In Delft ====

The main '''bus and tram station''' in Delft is next to Delft train station. Bus routes '''40''', '''69''', and '''174''' go from the station directly to the venue. The bus stop to get off at is '''Delft, Mekelpark'''.  The ride takes about 10 minutes.

'''Walking''' to the venue from the main Delft station takes about 30 minutes (2.5 km), and from Delft Campus train station about 15 minutes (1.3 km).

==== Train and bus tickets ====

You may now be able to check in and out using your [https://ovpay.nl/en/frequently-asked-questions#what-payment-methods-can-i-use-to-check-in-and-out contactless debit card, credit card or mobile phone]. That is already possible for all NS trains (for travel in 2nd class). The same goes for *most* bus and tram companies. See the [https://ovpay.nl/en OVpay] website for full details and updates.

You can also use an '''anonymous OV-chipcard''' to travel by all forms of public transportation in The Netherlands. This is a blue-coloured card with no personal details on it, and can therefore be used by anyone (but not for group travel). You can buy an OV-chipcard at the train station at an NS (Dutch Railways) ticketing machine or NS service desk. It can also be bought at large supermarkets (Albert Heijn, Jumbo) or tobacco shops (Primera, Readshop, Bruna). The price is €7.50. It remains valid for 5 years.

The OV-chipcard gives you access to travel in 2nd class. You need a balance of at least €20 to travel by train. You can charge credit on your OV-chipcard at the ticket machines at the train stations and tobacco shops. Once credit has been charged onto your card, you can check in at the designated posts or turnstiles, which are usually located close to or on the platform. Don’t forget to check out once you leave any form of public transport!

In trams and buses you can also buy a paper day-ticket or a single-use, disposable chipcard instead of an anonymous OV-chipcard. For metros you can buy a ticket at the ticket machines near the platform or metro station.

'''Note: Most ticket machines do not accept cash, nor do buses and trams.'''

=== Accommodation ===

We recommend that you stay at  [https://hotelarsenaal.com '''Hotel Arsenaal'''] or [https://www.grandcanaldelft.nl/en/ '''Hotel Grand Canal''']. These hotels are conveniently located within 5 minutes walking distance of Delft’s main station, between the station and the university campus.

Other conveniently located hotels in Delft include [https://all.accor.com/hotel/B5M3/index.nl.shtml Ibis Styles Hotel], [https://westcordhotels.com/hotel/hotel-delft/ WestCord Hotel], and [https://www.thesocialhub.co/delft/ The Social Hub].

=== Registration ===

The registration deadline was on Friday 10 March.

The registration fee covers:
* the group lunches and dinners on Monday 3 and Tuesday 4 April;
* the EVCS lunch and social dinner on the Wednesday 5 April.

=== Excursion ===

Based on the registered interest for an excursion and dinner on Sunday, we have now arranged:

* a '''combined canal and guided walking tour''' in Delft from 15:00 to 17:30, and

* a '''dinner''' from 18:30 to 21:00.

(There was insufficient interest/availability for a Thursday excursion.)

Please see [https://www.aanmelder.nl/excursiondinner here] for further details regarding the locations. Registration for the excursion and/or the dinner has now closed.

The fee is '''25 euro''' for the combined canal and guided walking tour, and '''45 euro''' for the dinner (3-course, incl. 2 drinks). The restaurant doesn’t need advance notice of dietary restrictions.

=== Social events ===

An excursion and dinner on Sunday 2 April have been arranged (see above).

EVCS concludes with a social dinner on Wednesday 5 April.

''For those planning to stay an extra night:'' on Thursday 6 April at 19:30, the Bachkoor Holland with the Concertgebouw Kamerorkest will perform Bach's [https://www.bachkoorholland.nl/agenda/matthaus-passion-2023 St. Matthew Passion in Nieuwe Kerk, Delft]. (The ticket site is only in Dutch: note that the "Rang 3" seats have no view of the podium.)

== Touristic information ==

Delft is known for many things. The first things that would come to mind are '''Delft’s Blue Pottery''', the painter '''Johannes Vermeer''', and the University of Technology. But Delft also played a very important role in history of the '''Dutch Golden Age''' and the reigning of the Dutch royals (House of Orange-Nassau). It is recommended to visit '''Prinsenhof Museum''' for the history of the Dutch royals. Stroll down the city centre to visit the Old and New Churches, where you’ll find the graves of Johannes Vermeer and one of our first leaders: '''Willem of Orange'''.

You can buy an OV-chipcard at the train station at an NS (Dutch Railways) ticketing machine or NS service desk. It can also be bought at large supermarkets (Albert Heijn, Jumbo) or tobacco shops (Primera, Readshop, Bruna). The price is €7.50. It remains valid for 5 years.

The OV-chipcard gives you access to travel in 2nd class. You need a balance of at least €20 to travel by train. You can charge credit on your OV-chipcard at the ticket machines at the train stations and tobacco shops. Once credit has been charged onto your card, you can check in at the designated posts or turnstiles, which are usually located close to or on the platform. Don’t forget to check out once you leave any form of public transport!

In trams and buses you can also buy a paper day-ticket or a single-use, disposable chipcard instead of an anonymous OV-chipcard. For metros you can buy a ticket at the ticket machines near the platform or metro station.

'''Note: Most ticket machines do not accept cash, nor do buses and trams.'''

== Touristic information ==

Delft is known for many things. The first things that would come to mind are '''Delft’s Blue Pottery''', the painter '''Johannes Vermeer''', and the University of Technology. But Delft also played a very important role in history of the '''Dutch Golden Age''' and the reigning of the Dutch royals (House of Orange-Nassau). It is recommended to visit '''Prinsenhof Museum''' for the history of the Dutch royals. Stroll down the city centre to visit the Old and New Churches, where you’ll find the graves of Johannes Vermeer and one of our first leaders: '''Willem of Orange'''.

We will follow our usual format of interactive talks with an active audience, but this time making use of a chess clock for timing, as follows. For each talk the speaker and the audience each get at most 25 minutes. The audience does not have to wait until the end of a talk to ask questions; interaction and discussion is encouraged. (But experience from previous meeting shows that it is useful to let the speaker at least finish their introduction before interrupting.) To ensure fairness, administration of the time used by each party is done using a chess clock. Operation of the clock rotates among participants. Both speakers and audience are expected to contribute to make talks and discussions engaging, interesting, and useful. Therefore, we observe a policy of no use of electronic devices during talks (other than the device the speaker uses to present slides). Bring paper and pen for making notes.

== Travel Recommendations ==

People travelling to Salem over the weekend have reported somewhat mixed experiences with the public transportation system, excerpt:

* JL: The commuter rail was substantially less easy than expected. I was expecting something that runs every 5-10 minutes, but actually it runs every 1-2 hours. Theer are trains from Chelsea at 2:40, 4:40 and 5:40 (verify on the the mbta website). From the airport, you take the 33 bus (free) to the blue line (airport T station) and then silver line 3 to the commuter rail at Chelsea. I don't know if one is supposed to pay for the silver line or not. The driver didn't seem very interested when I asked if it was necessary to pay, but other people were using tickets. At Chelsea, the train is just to the right of the bus stop. There is only one platform that says inbound. You wait there and cross the tracks to get to the outbound train. You need to wave at the train to get it to stop. I bought my ticket with the mticket app, so I don't know where or whether the tickets can be bought at the station. Taking a taxi or uber may be a simpler option.

* JG: I asked for directions at the airport information desk - they recommended instead going into the city and catching the commuter train from there. From the airport, take the Silver Line 1 bus to South Station, then the red then orange T lines to North Station, from where it is a short walk to the commuter rail station (underneath TD Garden, a sports stadium). At least there is a ticket office at North Station. Of course, the trains go no more frequently. I understand that the SL1 and T is free all the way to North Station (though in fact I walked from South Station to North Station, to get some daylight).

'''Relational Algebra by Way of Adjunctions''' by Jeremy Gibbons (based on joint work with Fritz Henglein, Ralf Hinze, and Nicolas Wu; this is an extension to the work I reported at [[WG211/M15Schedule | Meeting 15 in London]])

Bulk types such as sets, bags, and lists are monads, and therefore
support a notation for database queries based on comprehensions. This
fact is the basis of much work on database query languages. The
monadic structure
easily
explains most of standard relational
algebra - specifically, selections and projections - allowing for an
elegant mathematical foundation for those aspects of database query
language design.
Most, but not all: monads do not immediately offer an explanation of
relational join or grouping,
and hence important foundations for
those crucial aspects of relational algebra are missing.
The best they can offer is cartesian product followed by selection.
Adjunctions come to the
rescue: like any monad, bulk types also arise from certain adjunctions;
we show that by paying due attention to other important adjunctions,
we can elegantly explain the rest of standard relational algebra.
In particular, this leads directly to an efficient implementation, even of
joins.

'''Profunctor Optics and the Yoneda Lemma''' by Jeremy Gibbons (based on joint work with Guillaume Boisseau)

''Profunctor optics'' are a neat and composable representation of bidirectional data accessors, including lenses, and their dual, prisms. The profunctor representation exploits higher-order functions and higher-kinded type constructor classes; the relationship between this and the more familiar representation in terms of "getter" and "setter" functions is not at all obvious. We derive the profunctor representation from the concrete representation, making the relationship clear. It turns out to be a fairly direct application of the Yoneda Lemma, arguably the most important result in category theory. We hope this derivation aids understanding of the profunctor representation. Conversely, it serves to provide some insight into the Yoneda Lemma (which we will explain as we go along).

=IFIP Working Group 2.11, Eighteenth Meeting=

This page is, obviously, incomplete. As information is completed group members and visitors will be notified.

== June 4-7, 2018 in Kyoto, Japan. ==

The meeting will be held in Kyoto, Japan, hosted by Atsushi Igarashi.

The meeting will last 3.5 days; the first three days (June 4-6) will be full-day, whereas the last day (June 7) will be a half-day session.

=== Venue ===

The meeting will be held at Kyoto University.

=== Travel ===

[https://www.kansai-airport.or.jp/en/ Kansai International Airport], located south of Osaka, is the natural access route to Kyoto. From there you can reach Kyoto Station in 1 hour 15 minutes, using the Limited Express HARUKA (runs twice an hour). Another option is to use a shared taxi (shuttle), which you should book in advance, operated either by Yasaka Taxi or MK Taxi.
You can also fly first to Narita International Airport or Haneda International Airport in Tokyo, and then connect to [https://www.osaka-airport.co.jp/en/ Osaka Airport (ITM)] from which you can take a limousine bus or a shared taxi to Kyoto. (If you are a train fan, it may be a good idea to take Shinkansen (superexpress train) from Tokyo to Kyoto, although it's an expensive choice.) [http://www.centrair.jp/en/ The Central Japan International Airport], nearby Nagoya, provides an alternative access route. The Mu-Sky limited express to Nagoya runs every 30mn (and takes 30mn), and from there to Kyoto is just 35mn by Shinkansen (albeit a bit expensive).

The organizer will conduct a survey for those who would like to use the shuttle bus from the airport.

You can check timetables for trains inside Japan on [https://world.jorudan.co.jp/mln/en/?sub_lang=nosub Jorudan's Norikae-Annai] or on Google Maps.

=== Sento ===

Jeremy suggests the following: I thought it would be helpful - for those like myself, arriving early in the morning but not able to check in to a hotel in the afternoon - to point out that that it is easy to get a nice hot bath cheaply in Japan, in a public facility called a [http://www.sentoguide.info/etiquette/ sento]. You have to be comfortable being naked with strangers (of the same sex); but there is no better way to relax after a long flight. However, note that tattoos are not welcome.

As it happens, there is a basic sento in the basement of Kyoto Tower, which is just across the road from Kyoto Station where people are likely to arrive in the city, open from early to late: [https://www.keihanhotels-resorts.co.jp/kyoto-tower/en/ Kyoto Tower Daiyokujo Yuu 07:00-22:00 (basement 3F)]. But Atsushi has recommended a "super-sento" (a fancier place, with several different pools, masseurs, restaurant, a bit more expensive) called [http://hanano-yu.jp/ Hana-no-yu はなの湯], one station away from Kyoto Station, which is open from 10:00.
