 Hello, EMF 2024, planning has already begun hello EMF and welcome to the beginning of the end of this one planning for the next one begins of course tomorrow a lot of people have from a lot of teams have done a lot of work over the last few months to make this event happen a lot of it hopefully was invisible so we're gonna have a whistle stop tour through the various teams that have been involved in this event not all of them I'm afraid just the ones I managed to collo in the bar last night and we'll begin with the with the site where everything always starts yes hello this is going to be a bit powerpoint karaoke because I haven't really gone through these slides in any detail and I didn't write any of them people have just done them for me so yes we got here Wednesday of last week Tuesday Tuesday of last week and and go into the field and just plug the internet in which is quite easy this time and this is kind of the state of our storage unit before the event you'll you'll see that it's very tidy and it won't be like that by the end of next week we had some vehicles we had some vehicles that broke as they tend to do we had some more vehicles these also broke because as they tend to do but they are all still just about drivable um we have a shit truck um which is great actually I really like the amount of time you spend running a festival is mostly dealing with fluids of some sort or another and um and uh we produced a lot of wastewater because you all like showers which I find a bit weird just get rid of that spider um fluids more fluids we had we had a really quite significantly increased plumbing operation this time um including some tremendous artwork from ben here um installation plumbing um we had a shower on top of a tank that's our crew shower which uh we were using for build up and um oh hang on yeah so we did put a lot of we we bought a lot of plumbing fittings hopefully we can return some of them um we there was like a thousand pound screw fix order because we're like how many pipes do we know I don't know just just just stick a load on screw fix um lots of lighting 1.2 kilometers of this festoon lighting which is important so you can see where you're going on trip everything's we got these radios um which were quite nice um we got we got upgraded I think we got upgraded because I told the guy who was hiring them to us they were all nerds and um and they were like oh we've sent you all of the nice radios and I'm like oh shit well hopefully we don't lose any then um we got a battery back our repeater which actually proved useful when the power failed yesterday um that was on the grid power obviously like oh the grid power's not going to fail but we might as well get a battery on there anyway um which was good um we had a significantly increased gas set up this time for the volunteer catering which we were like oh we'll sort that out and then a couple of weeks ago we were like oh we're not going to be able to sort that out ourselves so we had like one inch gas pipe and all sorts of nonsense installed by a supplier um I think they have to come and uninstall it as well we had a lot of construction stuff which you may have seen around the the kind of boring stuff like sinks and work tops and things again this is this is something that we were like oh well just finesse it while we're on site and then it's like oh we need quite a lot of wood and things and post boxes and sinks and I don't even know what else I didn't do any of that signage um we we have to pay for signage because the council likes us too so you will probably have seen those signs on the way in um we changed them a little bit over the last time because last time it said eastern castle and the castle got a lot of visitors so um we uh we there's there's a bit of an art to all of this which we are still learning it turns out steam festival Jesus there was a steam there was a steam festival last weekend and and they were not very good at finding the right entrance and a lot of them came in here and they're like is this the steam festival I'm like does it look like a steam festival it's the complete opposite of a steam festival I didn't go to the steam festival I think Mark did great it was good apparently you should go next year um power which I'm also doing this was our power plan for this year you're not expected to read that um we have slightly improved I wanted to improve it further but I didn't have enough time the out the computational power planning software from last time so that pre-calculates all of the stuff and tells me whether either the cables are too long or you know the breakers won't be able to trip in time and stuff like that um that's all kind of printed out and then Matt laminates it all and um scribbles on it and uh and well basically what happens is our power supplier sends us a slightly different set of stuff from what I plan for and um and then we have to spend our ages working out if we've got enough sockets for everything so that was last Saturday or something we also had two power deliveries this time we got some build-up power with this um fetching pink generator which broke and um twice and uh and um and some other stuff some diesel this is the fluids again oh god there's another spider um I didn't know what you were talking about with these spiders there's the third one um and uh yeah so we got that that arrived last Wednesday and uh gave us enough stuff to run our heated blankets and so on the important stuff and and uh we also got this hybrid power box which you may have seen on kind of beautifully displayed along the track way down there um which we got primarily because we need a backup power source for the festoon sight lighting but uh we also used it for build-up so we could turn the generator and have a turned generator off and have a nice quiet night um it also runs python it turns out didn't do a huge amount of hacking on that one because it's not being used for much in during the actual event it maybe it saved us a little bit of diesel as well because it's more if the generators are quite inefficient when you run them at a low load so um if you can do it off the battery instead that's more efficient in theory but that's the start of our like battery power and renew slightly more renewable things we'd love to get into not burning so much diesel but especially given the prices have gone up substantially this year uh for various reasons but uh it's hard to get power in a field it turns out and uh diesel is quite an efficient way of bringing it and then our main power turned up a few days later on this enormous not a high ab um thing uh we we're a big fan of this truck it has visited our events several times before and um it can lift generators an implausibly long distance um that's where we put the you will you will probably have seen the the hybrid power thing during the event and that is just basically a big ups um it's even lead acid it's not even lithium um and then we did an increased amount of testing this year thanks to all the power team who went to a huge amount of work to get basically more tests than we needed we have so much data on this now which we're probably won't do anything with but um we have 30 odd pages of electrical completion certificates um these slides are in a slightly random order so please forgive me if i'm not yeah so in 2016 we had a bit of a fuel shortage um the photo on the left there is the first outing of this it's now it's now past the statute of limitations on this photo um this is benny draining some red diesel from the telehandler to put in the generator because we ran that low um 2018 we were okay for fuel although the tanks unexpectedly arrived empty whether they thought we thought they were going to be delivered full so that wasn't terribly handy this year uh well um we bought a lot of diesel basically we increased the the we've increased the length of the event by the day we've increased the build up that means we have to turn the generators on earlier we've got one more generator than we have previously we've got four grids on site this time um and that means that we have more generators running at lower load drinking more fuel it's about 300 quids worth of diesel a day just to run those generators at idle um and uh so that was the fuel delivery of 6 000 litres that was about and then we got another 4 000 so um it was about 16 000 pounds worth of diesel i think including that um because we pay road prices for it now thanks to um thanks to the government very kindly changing the law while diesel prices were going up so i think we're good the power hasn't gone out yet i think we we we rather overestimated the the amount of diesel we'd need to run the generators so we didn't end up with a diesel shortage but we did end up with a lot of time faffing about with spreadsheets and trying to work out whether we would have a diesel shortage um which is terribly surprisingly hard we broke a few generators or rather they broke themselves um the fetching pink one broke while i was having a shower um and then when we turned it on again it would not sustain the correct voltage so yeah that's going back hopefully we'll get a replacement tomorrow because we'll need it and then the other one the alternated cable fell off which was not terribly useful well a lot of rcd programming this is me lying in the field trying to program an impenetrable user interface it's just horrible um we had a lot of trips of these for some reason this year which we'd not had in the past especially given that we were more fastidious in setting them up correctly this time but you know that's why null sector went dead a few times hopefully it will not anymore touch wood um and we did a lot of earth testing including of a tent peg i can tell you that a single tent peg is not an acceptable source of earth 580 ohms not good enough has to be below 200 and finally we got power monitoring working last scene i believe in 2016 which i was doing through rs485 but this time we kind of had the tacit approval of our supplier to reprogram the controllers to enable dhcp and and plug them into the internet well not directly into the internet obviously um so we all of that is on dashboard.umf.camp and uh i will have to save it so that we know how much fuel these generators drink when they're on certain amounts of load least used power distribution box nothing plugged in most used quite a lot of thing plugged in thank you for using 16 amp plugs we prefer them um and uh if you haven't then just chop the end of chop chop a meter off the end of your 13 amp cable reel and wire a plug in a socket on there and then you can use it as both that stands for itself that's that do not do that i don't know who did that or where they did that but don't do that i think that's actually shorted out that fuse i can't tell no not good not good at all co2 monitoring we also had for the first time this year thanks to graham who is also known for the lasers at null sector um we unfortunately uh so we've we've been looking at this from a covid safety perspective trying to keep co2 below 600 ppm means there's less chance of covid transmission that was true in pretty much all the stages most of the time as far as i can tell we don't have data for stage b as far as i know so maybe that one was a bit marginal but the rest the high lines on there are null sector and unfortunately we only just realized that these ndir based co2 sensors are triggered by stage smoke so those numbers are a bit useless but at least we know that it's below that level and now the lighting team yes an enormous amount of reading of regulations and design and testing goes into the power network far more than you would expect and the thing to remember is if your power goes off in the drizzle late at night it's not a failure of the power system that is working as intended to keep you safe and alive so uh lie will talk now about the lighting that's been so hi everybody uh on top of all the power stuff there's a lot of us that now do site lighting as a separate team so that means we have our own budget and we've managed to pull off a few bigger projects this year so the one of the ones you probably seen are the tent markers or pole toppers around the site and they light up this year rather than just stuffing festoon in the top of it on top of a ladder on top of a gator on top of some rather dodgy ground so it's a lot of eddy strip some esp and a lot of python put it all together and we get some nice color things that hopefully in the future we can reuse again for multiple uh event uh of course it goes into a lovely dashboard as everyone does with a nice bit of python uh in future we should be able to have synchronized lighting across the site as well it runs on art net as well as just being separately configurable which is what we use this year as we did run out of time a little bit and the other big thing that we got working last night is the hillside balls uh if you might have seen on the hillside over on that side last night big rgb uh rgb w uh festoon array uh full of these small little balls that we uh ordered lovely from china renting would have been uh meant many many more times is more expensive than just simply buying them so we now have them and they look great however i don't have any pictures of them yet because i only finished getting them done last night so please take pictures tonight uh here it is testing and it runs on a point-to-point link from the hillside over to here art net again we seem to love that sort of stuff so if you have any content as well we we're a little bit low it's 60 pixels by 19 pixels they're not the biggest thing in the world uh send me a message on ilc or try and find someone like me in the site power team and we might be able to get it on the site this evening no speaking of that networking i also am not entirely sure what order these slides are in now this has been there quite a few people editing this simultaneously um but uh yes a little bit about the network uh those of you came to 2018 will remember we put in a street cabinet down there down at the main road where our internet connection is terminated and then a whole load of fiber all the way up here this is what that looks like inside that's our circuit and mostly test devices because the fiber uh is then patched in on the right there and comes through the ducts all the way up to the site to this we found that we'd left ourselves a little note from 2018 that didn't quite work as expected but that was really handy for early build up because this was day minus eight i believe the the splice chamber there coming out of the manhole and providing immediate internet access um well after matt had done a little bit of fiddling looked a little bit like that with slightly less lightning than we were led to believe from the diagram that will provide it um so we now have uh thanks to uh some energetic rotting in the first week we now have fiber all the way to the very end of the site and we also have ropes pulled down all the way to null sector should we choose to use this site again into years time the fiber will hopefully all be there waiting for us as it was this time uh this is what the network looks like physically um you will see uh a lot of things that you can't read um we uh we like to patch wherever possible patch our fibers passively so that no single decay is a point of failure if there's a power outage in an area so when we look at the logical diagram here which is even harder to read you can see almost everything is connected back to the core switch um and only a few things are mostly copper downlinked and mostly within very short ranges from their upstream switch everything comes back to the nock DC as we call it thank you to the construction team for building us this uh this flap in our air conditioning hole to keep all our cables nice and dry onto this table we have two splice closures in there now one from last time and a new one from this time that's the new fiber that goes all the way to the end and the patch from there into our core switch which is the bottom one not the microdick at the top that's a general overview we've got our servers down in the bottom left um our ups is in the bottom right uh some pox stuff above it some servers there and yes the the not quite load bearing table mostly for the relatively light switches and all the fibers this is a manhole this is the one down by null sector which is a new one that we've run fiber to this year after removing many many ants here's a typical decay so these are the locked portable toilets that you'll find around site um this is what they look like inside this one is by an underground manhole so you can see the other end of one of those splice closures sitting on the real there um and below it a real of fiber going to another decay nearby I think probably half of our decays now are served underground and the rest are on grass or running a long festoon yes and each one has a little switch and many many of these were constructed these go on top of the decay uh wireless access point the ohm light which up until this event was a very useful measure of whether the network was working in a given area we did actually have one stuck in the decay down by null sector which many people decided to report to us so we had a little bit change in our automation this time uh for many years we've been using a mammoth google spreadsheet um which uh was for a time a reasonable solution everything was driven from that we decided this was the year we're going to switch to using net box um net box we didn't have too many custom fields most of it is stock net box but anyone who's using net box will know getting a large amount of data into net box is very tedious so we did have a smaller spreadsheet driving it um I think we used about four or five sheets from that um but then once everything was in net box we ran that once to import it into net box um and then that drove everything it drove the provisioning the dns uh the switches um the dns servers and also the monitoring systems as well um and once it had run of course we could update net box if there was a last minute request and uh everything would filter downstream so these are the two main spreadsheets that we use um this is all the switches and where they're assigned to which switches they are how many ports are needed on each of the private vlands um and this is the other main one which is a master addressing plan which again creates prefixes in net box I don't know if this will play there you go this is running at 30 times speed so it takes a full 15 minutes to generate an enormous amount of data in net box from from those two spreadsheets basically um I don't have anything else to say about that so I'm not going to let it run all the way to the end and there we go in that box 141 devices I don't know is it say how many interfaces quite a lot anyway uh feeding things like this is our iSinger magvis map uh dashboard which has been sitting up in the knock looking mostly green all weekend and all of these all of these tools are in our github account um with the exception of ansible uh that we just need to make sure it doesn't have anything any usernames and passwords in it before we publish that that is how much bandwidth we've been using we had again a one gig link thanks to sky connect for sponsoring that um it was uh it was mostly mostly okay thank you very much for being considerate for the most part that is a flat line at one gig of it um but again thank you for stopping when we asked you to stop and many thanks to the people who emailed in asking to do a thing that would use a lot of bandwidth and didn't when we asked them not to so thank you for being considerate um no thanks for for this this is someone uh tripping on a fiber and dragging it at least five meters uh so that all of the slack and the actual fiber was pulled right out of the switch leaving just the connector this is actually not just a network down issue this is a safety issue because a a very very thin strand of glass fiber is quite dangerous if you get it in your skin other than that the most interesting thing that happened this weekend was a power cut which didn't really affect the site well it didn't affect the site because we're all on generators but it did affect the street cabinet um we have a ups down there uh so the circuit from our provider goes into an nte device uh a demarcation device which fortunately has two power supplies one on the mains one on the ups so we got early notice of this but it turns out that ups is a very hard to calibrate if they have 0.0 percent load so there was a bit of a panic not knowing how long the power cut was going to last and how long the ups would last um i think we were probably going to be okay for about three hours but um just in case here's another ups um and and just in case here's a tele handler bringing your generator down from the site uh we did actually win win that race but only by about five minutes impressively uh according to western powers website uh even though it only affected 300 properties it was back within 45 minutes we were back within 40 not not bragging um and i'll pass over now to ak to talk a little bit about the wi-fi and some of the logistical issues we've had so um across the event we've seen about um almost 11 000 unique devices on the network which is about uh 3.6 device per visitor assuming around 3000 visitors uh five and a half thousand devices of those were smart devices smartphones and tablets and such um 3100 esp so those are the expressive devices which are um this chipset is also that's being used in the batch and around um 1800 workstation laptops etc and this was on the wireless uh and the wired network by the way for the wireless network uh we've seen a peak of about 3000 wi-fi clients and this was across 97 80 to 11 ac access points uh from aruba and the peak of traffic was around uh 750 megabits of traffic uh something different of then wi-fi is the uh this logistical situation we had to go through to get all the equipment from the Netherlands and Germany to um to the UK so and that's just because of the um changed regulation situation with the united kingdom and because of this we needed to apply for a um what what we call in uh atah karnet uh or this is a sort of passport for goods um so we had to apply this uh through the uh local dutch chamber of commerce or camera from cope handle portal and then once we've got this karnet we needed to use a rather expensive courier um to get all the equipment uh into the country and pallet shipment was not really an option for this uh because it would probably take too long um so with this uh camera from cope handle website we ran into some quirks so one of them is that we in the portal portal we could only um have a list of 45 lines but we needed 300 uh and then we could maybe group um yeah our the items we had on a part product basis but then we ran into a limitation where we could have maximum uh 255 characters of serial numbers in this list so this was a bit interesting so after some contact with the uh camera from cope handle um we found a workaround and that was that we could upload some custom pdf um which in a specific format and then we just put in a like general number of uh we had some telecommunications equipment so many kilos so many uh this value and then it worked and they accepted it and shipped the karnet in the same day so in the end it worked out fine but the the hurdles we had to jump to are a bit inconvenient sort of say and we'll pass it on to logistics yeah okay yeah speaking of logistics the sheer amount of stuff that has to get here at the right time and get to the right amount of the right place on the site uh and then off again at the end is is staggering um so i'll hand over now to pes to talk a little bit about logistics i'm pes head of our logistics team a team that consisted of just me on site until one day before build please volunteer uh it turns out the field starts quite empty everything you see around you has been delivered and most of it has come through the logistics team all the stuff you've seen on the previous slides from the the furniture the bathroom the showers the big top the beer all the plants the club marty has all come through the team and we've had to position it on site liaise with all different suppliers and get things the way they needed to be we've accepted a truly ludicrous amount of deliveries uh and uh worked individually with over 75 different suppliers in the logistics tent we've had over 400 individual packages come into and out of the tent over the course the event and i'm just going to call out some of my personal favorites which include a 46 parcel amazon delivery which went all the way to null sector it was the delivery driver's entire route he came here dropped of everything that was it done there was an entire tesco van of milk for weight limit reasons they're only allowed to put four bottles of milk in each pallet so the entire van was just our milk nothing else she was also clocking off afterwards uh all of the wood chips you've seen around site which has been magically appearing wherever mud is it's not magic the team helps but uh it's been a lot of effort getting that distributed and my personal favorite are firewood supplier who delivered all of our firewood and rang me an hour before he was supposed to deliver everything telling us he'd accidentally set fire to all of his wood and all of his shed so that was a bit of a disaster but the wood got here we had wood it was all fine uh i limited myself to only three slides because i don't want to run over so passing over to funds yes it turns out that if your amazon app is telling you the driver is eight stops away the other seven stops are actually different teams have used a slightly different address for the site so we were graced again this year with the marvellous phone network i hope you all used it there was of course dex and uh sip but also an auger phone system and here's sam to talk about that thank you so yes uh my name sam i um head up the pock phone operations team um so a bit of the the couple of guys from event phone who've been able to help they've already headed back to germany but um we had deployed 38 decked antennas they look much like the wireless access points but they're a bit flatter and have four leds on them um if that's the only real difference you can spot uh we also deployed 35 sip phones so pretty much every tent had a had a wired sip phone um i also staged 35 sip phones in my office at home two weeks ago uh with a lot of cables um 54 pots phones the the wired dial up the old-fashioned kind of you know analog twisted pear copper that that math you did um he had those devices we also had two um dual mode gsm lte cells on site which you may or may not have noticed um and i'll talk a little bit about that later and we also got a wi-fi calling working which was a sort of pock knock thing because phones are just ip these days um but we we managed to do that thursday with a bit of hackery um few calls that so we had 390 decked devices on the network uh 250 sip 54 pots um 16700 calls internally through the system which is quite a lot for that so people were some people must have just been sat there like yeah dialing with it um we also deployed a jam bones server which is uh like a your own private programmable twilio type service um so if you build created applications into total 69 applications on that but half of those were probably my workshop um 846 calls so some of the 555 numbers you saw around like you could call matt's booty call app and things like that there were some cards distributed um 555 duck if you haven't tried it by the way just this was yeah the wi-fi calling um so previously as you may have noticed wi-fi calling didn't work um mainly because we have a german ip range and the uk carriers think you're in germany and won't let you use wi-fi calling when you're abroad um so we tunneled all the traffic for wi-fi calling back um through an l2tp tunnel to my isp um and currently all of your carriers think you're at my house so yeah 290 uh 2983 unique ip addresses which i think should be pretty much a unique mobile if they'd attach to the wi-fi um so that's yeah the number of phones not a lot of traffic though or in terms of volumes i mean it's you know it's voice calls it was we were doing that's a daily 600 megabytes a day transferred over that link and it was you know a few hundred kilobits a second um but it makes it quite useful uh the cellular stats so the say the phones that connected 3400 odd unique sim cards connected to our mobile network with that rough breakdown of different carriers um so yeah 720 calls and over the 4g about 27 gigabytes up and down of data over 4g uh and you may have had an sms saying you were in jersey um it's complicated um i can explain it more later if you're interested by finding the bar but if you did if you could forward the message to that number um it would really help us to build up a record because we can then look to they're trying to filter those out because you shouldn't get them but because of the the hack or the way it works you do um so yeah if you if you have that message please forward it to that number we just we're just logging the content of the text they're not even recording your numbers but we can then build a trainer spam filter to block them and that's me none of us would be here without a ticket well i i i hope no one's here without a ticket and here to talk about how the website uh works and how it has evolved this year is marked from team web uh try and keep this brief because there's not that much interesting infrastructure we try and keep the instructor boring um so uh since 2018 um we obviously had a massive uh rush to rework the website to sell t-shirts when the event was cancelled um but since then we've had uh 1400 commits uh almost 40 different contributors uh adding a whole load of extra functionality this year um so i just want to do a quick call out if if anyone wants to get involved in the website just check out our github repository and and have a look and um you know only on the issues or anything issue give us a pull request uh if you want to be on this on this list so thank you to uh uh uh ian and um robert for sorting out the reworking all the volunteering this year um john for the schedule rework john for the stage screens john for the village workshops um john for the attendee content page uh john has done a lot of stuff this year um he's he and if anyone's around do what who is happy to uh do the artwork he's he did all the artwork for the interstitial pages on the on these screens but he would rather someone who's confident with art um could could do that as well uh the herald interface from sam uh wise payments from j um and then various people did um bar training guidance from the wiki api documentation um that's all the new stuff this year learnings from this from the last few years um i know far too much about the the inner thoughts of canith rights now i don't use pip and it's not great um we're trying to get rid of gulp as well um and in fact it would be nice to get rid of javascript but there's only limit there's a limit to what we can do there um one of the it was only a week before the event that we realized that um the schedule was all showing wrong because um javascript's months are zero zero based so we had the we had the event starting in may do use docker we've we've dockerized the website that was another thing john did and it's it just makes everything much nicer and also staging ticket sales this year although the website can cope with very fast ticket sales it's not fun for anyone so we've been focusing on a voucher system and that just works much nicer and it's fairer um it would be nice to also stage arrivals oh sorry yeah this is this is the tickets ticket sales you can see them mostly sort of um creeping up with a few a few sort of initial tranches where people sort of panicked and bought them in a rush but actually most of the time that's not necessary um in contrast this is this is the arrivals um on thursday um the the peak is due to train delays and then everybody getting on a bus and you can actually see the train arrivals um if if people could just sort of arrive at different times that would be great just to spread out the load for the arrivals team that'd be that'd be lovely um um this is the combination of all the different um proposal uh content that people have proposed so so starting off with the call for participation but the massive ramp up the end is people adding their own stuff on site um which is great to see we had 561 proposals uh in total and uh over a thousand messages sent using the messaging system uh and then just because you have to have graphs for this kind of stuff you can see the um traffic to the website during the event um showing that people check the schedule at about eight in the morning and then sort of tail off and go to sleep at about two thanks uh i'm going to talk very briefly about about volunteering um and how it's evolved over the years um i don't it sometimes surprises me um that people that people don't know that emf is entirely not for not for profit uh any profit that we do make which is looking increasingly unlikely this year uh is plumbed into the the following event so everyone here on the auger team has bought their own ticket um we started in 2012 with 500 people and our mantra was everyone is a volunteer and that worked pretty well um this year we have uh six times well five times as many people checked in not everyone who bought a ticket checked in 556 unique people signed up for a volunteer shift thank you very much helping on site is great we need that we also need help build up we will need help next week tearing things down if you can stay a bit longer um i think we're gonna say uh come by the info tent in the morning yeah um because there is a lot to do and a lot of people who did the build up are now leaving or have left um are absolutely exhausted uh we need people to help us roll everything back in again equally uh if you are interested in planning the event for next time please get in touch a lot of team leads are quite keen to find co-leads or to hand over entirely for the next event uh but the time to talk to us about that is not a few weeks before the event it is many months before the event not tomorrow um but in a few months if that's something that interests you please do get in touch um here is an email address you can use volunteer at emfcamp.org um if you did do a volunteer shift you were awarded with a lovely meal from our volunteer kitchen i don't know if joe is here joe oh sorry behind me joe um yeah okay so uh this year has been the first year that we've had supplier deliveries um we got booker set up for the first time which resulted in uh an interesting um interesting situation you can see on the board there if you can notice uh that every one of those items has a one in the quantity column so there's an interesting feature on the booker website uh where you can create these shopping lists uh to add to your cart later if you then remove the contents of the shopping list from the cart the quantity resets to zero which you may not notice when you then add everything to the cart again we were a little surprised when our delivery on wednesday had one loaf of bread and one packet of corn flakes however we did have some really amazing local suppliers including pengethly farm who have supplied us with oh 1500 eggs over the course of the event including 500 of which james from pengethly drove over in his car on saturday we also had pj jones um who've come over all the way from wales and seemed really really interested in the event it's really lovely to have them apparently they go up at two o'clock in the morning which is even earlier than our breakfast shift 800 servings of crumble i'm told that was very popular uh v one of our volunteers made that speaking of which uh we have so many people to thank this hasn't quite updated with everybody i put on there uh you might remember fish he's the guy in the chef jacket who never seems to sleep or leave the kitchen um he's also kind and considerate despite that he's left a buffet open all night for the security people uh one of whom came by at four o'clock last night to request uh some of these crumble uh also have to thank pinglass who did our breakfast shift last year fish wanted to thank him for being he says the other half of his brain nicholas who signed up just to do breakfast made the mistake of turning up three days early and ended up doing 50 of the kitchen workload until other volunteers showed up thank you so much v we've already mentioned v is a dishwasher in a fine dining kitchen in their day job and has been blossoming into a full-on full-time chef in our kitchen here uh just amazing work it's delicious food that they've been making briny has her own catering experience done festival catering themselves um came by about nine p.m. volunteer to just do all our washing up all of it and then came back the next day and did it again uh noam and pescota who i'm told were really incredibly valuable for coordinating our angels on shift thank you natty and robert helping with planning all through those months before you know where we're trying to get everything going get all our menus planned really really helpful um one final thing i should mention which i don't have on these slides which is if you were kind enough to volunteer for our closing shift between nine p.m. and midnight you deserve a special reward may not remember to give it to you dropped by the kitchen later today thank you and i think what's happened here is that i've edited the slides while they were already presenting and there is now a feature that stops someone doing this which will prevent surprises like i had last time when will put in the slide saying many executive producer david croft um i don't know if there's anyone here from first aid who wants to talk about first aid oh yes there we go so we've only got 106 slides to get through um for the first aid um so we sit at the back in if you've come and seen us you've probably been been hurt but there hasn't been any really serious incidents on site um which which is really good if you've died put your hand up i can see no hands because the blinding lights which which is which is good but in seriousness um a couple of weeks ago um we had some a lot of issues our license was pending on all of the first aid cover and things like that we had to make some really rapid change very very rapidly make lots of people disappointed that they weren't going to be able to come to emf um so thank you for those who could come and attend because they're qualifications so just some statistics we've had an a and e consultant on site we've had nurses we've had free a and e consultants i'm now told free gps uh free gps we've had nurses we've had minor injuries specialists we've had paramedics we've had um everything from frek free up to a and e consultant so they're keeping you safe and it's it's been really good some of the low lights will i say cool um is a lot of the sort of slipshirts and falls um that's been our bread and butter as it were um our most serious incident was someone cut themselves and needed to um be stitched so we were able to do that on site the whole point that we wanted to do was to stop things going out to hospitals um a lot of obviously we we know the NHS is under pressure and we know that there's a lot of stress there we haven't sent a single person off site they've all been able to be treated here because of the the people that have helped who here didn't pack appropriately for the british countryside definitely more you're lying um yeah massive thank you for everybody for being sensible massive thank you for all our volunteers for oms who provided the ambulance next to us and for nip about who did all of our safeguarding on site um i think that's it thank you very much for not dying so another thing people often don't realize about emf is that we deliberately try to keep the ticket price as low as possible to make the event as accessible as possible so your ticket pays for the basic infrastructure it pays for the tents the toilets the sanitation and so on and so forth and all of the shiny stuff comes from sponsorship and support of of of our supporters i'm very tired um john t i'm sure we'll be thanking the sponsors in his closing presentation but i want to thank now our supporters who give us things that may just can't buy you can't buy an internet connection to a field in herford for one week for example we couldn't buy 50 switches and put them in the storage unit for two years in between events so i would just like to say a special thanks to all of these supporters sky connect lonap event info sargasso pylon one mythic beasts i3d ask for and contact thank you very much we would like to do better i fully accept that the network we built this year is not the one that we would like to have built it is in fact in a few respects worse than the one we built last time a logistical issues of shipping 50 very heavy switches from the netherlands meant that we couldn't quite build the network we wanted we would like to get some of that kit here in the uk if your company is mothballing um switches that are more modern than our 2000 era switches that we're currently using in the network um if you are removing servers that you don't need uh that are more modern than our eight-year-old servers that are currently running in the nok dc um switches with 10 gig or better up links uh can you help us with the connectivity to the site which it may or may not be here we don't know yet but please talk knock at emfcamp.org if you have something to give away and it's useful we do have storage we can take it at any time you don't have to store it for us we'll take it we'll arrange someone to come and pick it up clean it um sanitize it and put it in storage um so please get in touch if you have something to offer and if you'd like to volunteer for the next event get in touch volunteer at emfcamp.org for everyone who helped build this event all of my colleagues all of the volunteers everyone who came first set up everyone who will stay for teardown many thanks
