2016 Cambridge DevSummit ('BSDCam')
The 2016 Cambridge DevSummit was scheduled for 15–17 August. Registration was at bsdcam.cl.cam.ac.uk. You can also find a city map, building floor plans, and overall schedule on the BSDCam website. Please also add yourself (and your guests) to the attendee list below, and be sure to add potential discussion/presentation topics for sessions you might be interested in participating in. The event is run "un-conference style" in that we brainstorm the actual session schedule on the first morning, with a focus on interactive topics that reflect the interests and exploit the knowledge of the attendees -- but there's also room for traditional talks, etc. There are plenty of break-out rooms for small groups to meet as they see fit.

Schedule
The schedule has been posted on the DevSummit website.
The main Devsummit room is FW11 (First floor, Northwest corner of the building); other rooms are available for break-out sessions and working groups. Coffee will be provided prior to events starting promptly at 10:00; lunch is at roughly 12:00 each day; we plan to conclude technical sessions at 17:00(ish). Lunch has been arranged (and is included in registration), and dinner bookings will be made (not included in your registration -- details the formal dinner will follow). We will confirm dinner head counts each morning in order to size reservations suitably. Note that the Tuesday-night dinner required an advanced RSVP, and no further seats are available.

Organiser |
Preferred day(s) |
Brief description |
Teaching with / about FreeBSD |
- |
This session will be about continuing to expand material to support teaching with and about FreeBSD -- from Cambridge's L41 to training material developed on using DTrace, etc. Notes: https://etherpad.net/p/teaching201608 |
|
Auditing, Tracing, and profiling tools |
- |
This session will be about ongoing work on DTrace, PMC, Audit, LLVM-based instrumentation, and more. |
|
Supporting new memory-safety and mitigation technologies in FreeBSD |
- |
New hardware technologies are arising, whether research systems such as CHERI, or Intel's recently announced CFI protections, etc. There are also a host of compiler-based safety techniques used for CFI and other forms of mitigation. This session will discuss whether new OS abstractions are needed, which technologies are most promising to support, and what the compatibility, security, and long-term maintenance implications are for FreeBSD. |
|
QEMU bsd-user RISC-V support |
Earlier is better |
Start work on Tier-2 Package support for RISC-V |
|
- |
We need to have easy ways to hook into provisioning systems like Cobbler, Packer, etc and then hand over to Configuration Engines like Ansible,SaltStack,Puppet,etc |

Floor plans are available here: Maps of the William Gates Building and surrounding area.
You are specially interested in the 1st floor (EU/UK counting: ground, 1st, 2nd), WGB 1st floor room map
Logistics
Cambridge, UK is located approximately 45 minutes North of London by train, with easy access by bus or train to St. Pancras International - Eurostar (45m rail), London Stansted Airport (40m rail), London Heathrow Airport (LHR - 2h rail), London Gatwick Airport (LGW - 2h rail), Manchester Airport (MIA - 4h rail), London Luton Airport (1h25m bus). European attendees may consider Eurostar or Stansted Airport preferred routes due to short transit time to Cambridge and lower prices. Visitors from the US or elsewhere will likely need to travel into one of London's major international airports, such as Heathrow or Gatwick. With the exception of Luton Airport, rail offers a more convenient but more expensive route to Cambridge than bus.
There is a bus ("The Universal") that travels past the railway station going west towards Churchill College, and then the William Gates Building. The Universal runs every 15 minutes on week days, every 20 minutes on Saturdays, and not at all on Sundays. Universal bus route map, Universal bus timetable. The William Gates Building is the first stop on JJ Thomson Avenue. It is probably faster to walk between the William Gates Building and Churchill College than take the bus, as the are quite close together.
Please note: during the summer, rail service in and out of Cambridge is sometimes disrupted on Sundays due to rail works on the track between London Kings Cross and Cambridge. Attendees are encouraged to avoid the need to travel by rail on Sundays.
Lodging
There is a 40-room block booking at Churchill College. The reference when booking is REF 39218, which attendees will need to mention when making their individual registrations and paying. They’re mostly en suite rooms, but there are a few that have shared bathrooms. Use Comp Lab Guest Accommodation Reservation Form.xls to reserve accommodation.
Bike Hire and Collection
Cambridge is slightly too large to be convenient to walk everywhere, but small enough to be ideal for a bicycle. If you have a car, please be aware that you will not be able to drive in the city centre and you probably won't want to drive near Cambridge. The roads were designed for horses and have adapted well to bicycles, but not to anything larger.
Rutland Cycling (previously Station Cycles) rents bicycles at a reasonable rate. Please book with them directly. You can probably just turn up and get a bike but it's better to send them an email to make sure that they're not going to be surprised when 30 people turn up at once.
Prepaid SIM Cards
If you need cellular service in the UK, a number of operators sell SIM cards. You can usually buy a SIM card for the Three (3) network from a vending machine at Heathrow Airport for ~£20. You can also often buy them from airport shops such as W.H. Smith. BrooksDavis reports that he uses £2-3/week of data while in Cambridge so if you will be in the UK often enough to keep your account alive, it's often a better deal to not activate the offered data bundle and just use the credit. If you take that option, top-ups can be purchased at most Airport shops and any mobile seller.
Network access
We will hand out "Lapwing tickets" during the opening session; these are preferred to the open WGB access point due to using JANET rather than a commercial DSL line. See http://www.ucs.cam.ac.uk/network/rules for University network access rules (AUP). Plan on bringing an Ethernet cable for possible wired access in your room (depending on accommodation).
Using eduroam (UniOfCam) with tickets on FreeBSD
I am not sure if you need the CA cert but I downloaded it following UCS instructions from: http://www.ucs.cam.ac.uk/mobiledevices/certificate-conversion.html The main trick was that UCS requires the outer (anonymous) identity to either be your real user name (which you normally do not want) or be empty. The identity (UniOfCam Ticket-Id) can be supplied with both the three dashes or without, so keeping it in seemed natural. The main thing pb helped me to find was that the Realm needs to be @wireless.cam.ac.uk: http://www.ucs.cam.ac.uk/network/other/radius#lapwing-tickets So here's a wpa_supplicant.conf that (once) worked for me. network={ ssid="eduroam" key_mgmt=WPA-EAP eap=TTLS PEAP phase1="peaplabel=0" phase2="auth=MSCHAPV2" anonymous_identity="@wireless.cam.ac.uk" identity="xxx-xxx-xxx@wireless.cam.ac.uk" password="xxxxxxxx" ca_cert="/tmp/AddTrustExternalCARoot.crt" } Note: in case you previously were using "lapwing" you want to change that, as the system was renamed mid-2014. /bz
This is what cperciva needed to get eduroam working using his credentials from a Canadian university; allegedly all Canadian universities do eduroam the same way, so this may be useful for members of other Canadian universities: network={ ssid="eduroam" proto=WPA WPA2 key_mgmt=WPA-EAP eap=PEAP group=CCMP TKIP identity="cperciva@sfu.ca" password="XXXXXXXX" }
Travel coordination
Registration is on the Cambridge Computer Laboratory website. The fee is 65 Pounds Sterling (GBP) and covers the costs of lunches, badges, shirts, etc.
You can co-ordinate travel and find people staying in the same place as you here:
