 I would like to ask Emmanuel Brethel to go to the stage and the friendly guy from the projector service told me I have to put off one or two fingers one is for Mac or digital the other is for VGA you know you know which finger is what good so I will try it and maybe who has been here Monday good you remember that a joke with the three logicings going to a bar yeah somebody told me there was a major bug in it and he was totally right that bug that joke was not passable and now we will have quick service prototyping and later we will have the bug resolution before we get a quick prototyping I need a better vector Victor in you are back are you better no he is better good okay now please a big hand to Emmanuel Brethel about quick service prototyping like him on Facebook hi everybody I'm going to talk about spots which is a library to quickly prototype services and basically help you into implementing things more than setting them up so what he takes to build a service usually after the command line arguments you will set logging you will set up the service and you will also have your task that is a job you will have to manage them and then you will have your implementation in Facebook we love thrift we use it everywhere and this is what it looks like to make a simple service kind of handle arguments set the logging here are trained by a thrift handler and the thrift transport and I start the service what's part does it kind of remove some of the few steps you have to do so you don't have to handle arguments anymore you don't have to handle logings you still have to set up the service somehow you don't have to manage your task and you have to do the implementation because that's what you want to do right so this is the same example here I'm importing stuff from spots I'm creating my thrift handler but I don't then I just register the task and then I initialize the service where it gets a bit more interesting is if you start adding more tasks here I'm adding a periodic task that will be triggered every second basically and all I have to do is I implement the task and register the service the task story and then start the service and even more tasks there is a default tornado HTTP task that does not much but then you can subclass that and basically do the do what you want with it there is other tasks supported like cues and directory watcher deboss every through three twiz the you might actually implement any other kind of task all it will do it was it will help you into starting the other loop of your of your task and shut it down when you need to how to get it people install spots and otherwise you can go and get it from github and aside from that we are also hiring so you can come and talk to me if you're looking for something different thank you thank you so much I need Udo Spallek wait wait wait you have to be liked you're from Facebook so you won okay Udo Spallek Udo you're here very good so to fix the bug with the three logic and what I missed out the bartender asked him do you all want to have a beer and now the joke is easier to understand because the first one says I do not know the second one says I do not know the third one says yes now it works bigger than I thought okay he is still working who will be staying for Sunday in Berlin make sure to look around because there is a crazy American billionaire who will be hiding money around Berlin and that's not even a joke or at least I have watched TV this morning for five minutes and they told there will be hidden envelopes of money most likely even euros so our next speaker will talk about Blinky's asking adventure so I guess that's a return of the blink tag in HTML your stage give him a hand well actually Blinky is this little guy here he's blinking and here's Blinky source code it's nothing complicated there's some delays in a loop and now Blinky is first nervous in front of this whole crowd and secondly sad because he doesn't have any friends how do we fix that we can use the threading module because threads are easier right okay this is different screen than I tried with okay so the only thing that changed here is there's a different function to print the Blinkies it's you know an external function there we make more Blinkies in a list and then we just start them and they're all blinking happily the problem here is well Blinky is happy now because he has friends until a system upgrade comes along with a new enterprise ready print Blinkies 2.0 function that does a little more than previously and we have trouble because all these Blinkies are trying to print themselves well print all the Blinkies so they're overwriting each other's lines and it's just a huge mess and we should use some blocking here but you know this is a problem that you know library changed we don't have control over it so you know that's a problem so what do we do we look at what Node.js does and we use callbacks and futures now what this does is every time we call it non-blocking or a long function we add a callback to it specifying what needs to be done next after this sleep is done so here we schedule open eyes here we schedule close eyes everything works everything's nice the good thing is that if you schedule something the entire thing runs in a block there's no interruptions the print Blinkies can't introduce any interruptions because it would have to change its signature we would have to call it a different way so everything's nice the problem here is these two functions are a loop right well it's not really a loop it's a trampoline thingy there but what we want is a loop what it does is a loop and we would like it to look like a loop and this is what async.io which async.io solves somebody some of you probably heard of async.io and what async.io does is let us use a loop for it we use this yield from which lets us know that this is a function that can result in a context switch it can switch to another you know like thread of execution so we have to be careful because things can change from this function to this function but in between these yield from it's again run in a single block without any interruptions so I hope this cleared up for some of you what async.io is all about and all these other async things and thank you thank you so much you earned your lightning torque man superhero card and do you know what's the big brother of Blinky Clippy who remembers Clippy so you're trying to rise your hand do you need help with that that's Clippy and we also need baptiste miss Pellon miss Pellon oh it's the French miss Pellon our next speaker will be Udo Spalik about the Triton Unconference in Leipzig 2014 a bartender says we do not serve faster than light particles here a tachyon walks into a bar now the stage for Udo about the Triton Unconference in Leipzig give him a big hand hello my name is Udo Spalik I come from the Triton Foundation and I would like to invite you to the Triton Unconference in Leipzig it's a town nearby Berlin on one hour of the way 2014 1114 and we are talking there about the Triton framework and other stuffs the functional technical details there are users developers and so on you may ask what is Triton because it's not very known because it's just a small it has just a small domain of use first for the name we come from far away from Planet Neptune one of the biggest satellites is Triton with I and we name our our applications in the Triton framework all with names from the Satellites of Neptune Triton looks like this you can see three clients on the right side you see a GTK client in the middle you see some some web client some prototype of a web client and on the left down you can see a client which is for Python a library the architecture of Triton is client server based it's if you like multi-tier framework with web connections we use several protocols to bind the clients to the server we use usually usually for for persistence Postgres SQL or SQLite and we support a little bit my SQL but it doesn't work very good one special thing is the module tree you see on the left on the bottom there all functionality in the system is served by modules and we have good inheritance inheritance in the modules so you can build upon other modules your own modules for your special things you want to do the special things you want to do with Triton is usually something like accounting and invoicing sales purchases inventory stock manufacturing resource planning project management and party relationship management which is a little bit bigger approach than just customer relationship management so it's a business-related framework we use this Triton the most prominent user of Triton is GNU Health it is a medical record system it provides hospital information system and for the future it will provide an health information system because Jamaica decided to use GNU Health for organizing and managing their hospitals this is one view of an earlier version of GNU Health you see a patient record of a person and you see it's just the stuff you want to put in when you're a doctor and you want to see when you have a patient in front of you just install Triton use your favorite distribution you can just install it but you can also use Pi Pi source packages or whatever you need so I invite you again for the Triton Unconference thanks everybody Triton Unconference and I forgot my super hero card is Sein Verlust Anton I need you on stage Anton Tiorin are you here Anton you're here very good our next speaker will be Baptiste Miss Pellon about yet another conference announcement and he's adequately ready okay give him a big hand for yet another conference announcement thank you hi everyone like I said before I'm Baptiste I'm one of the Django core developers and I'm here today to announce you yet another conference I hope you're not bored of this so first I'm going to tell you a little bit of the story behind his conference last month I was on a train in Italy back from another conference I went with my friends Mark Daniele and me we were all on this Italian train so we had a lot of time to chat and we were thinking about Django about how the Django the Django source code is a bit complicated and there are some parts that only a few people know about and when we try to get other people to contribute we often need to review their code and if their code touches these parts that we don't know about it makes it really hard for us to accept it or reject it so we are looking for solution how we can get this knowledge to spread inside the Django team but also inside the community so we started thinking what if what if we could put the whole Django team inside one room at one time how would it look like maybe something like this but seriously we had this idea for a conference and we called it Django under the hood the idea is this we're gonna have a two-day conference on the first day there is gonna be there are gonna be eight talks eight one-hour talk very technical by prominent members of the Django community and the Django core team this is the the program that we want to work with and it's not been fully announced yet but that's what we're running with six heavily technical talk to spread the knowledge that these people have amongst the core team and amongst the community and I know you're all very curious because this is all very exciting where is it and when is it is going to take place quite soon actually on the 14th and 15th of November this is a Friday and a Saturday and it's going to take place in Amsterdam which should make it easily reachable for a lot of people we hope in Europe and in the whole world and the reason I'm standing here today not just to announce it to everyone of you but we're also looking for sponsors we're looking for sponsors to give us money so we can bring as much of the Django core team and of the Django community to this place at once we're gonna use the money we get for travel grants to get everybody as many people as we can to this conference so if you if all of this interests you or if you want to get in touch with us our website which we just launched yesterday with the help of the awesome Olas is Django under the hood.com you can reach us at hello at Django under the hood.com or follow us on Twitter at Django under the hood thank you very much thank you very much Baptiste our next speaker will be talking about the configurable omnipotent custom application in the created network engine it will be unturned urine and I like long titles that fills the gap between two talks so while he's setting up I set up an email address that's jokes at lightning talk man.com so if you think those jokes suck mine are even better mail them to me if you find bugs mail them to me and until you mail give Anton a big hand for the configurable omnipotent custom application in the created network engine Anton your stage. Hello my name is Anton I work at Yandex three days ago I introduced you one of our open source project named the elliptics and today it's time to another one project it's project named cocaine and it's application cloud platform it's platform as a service and this name means nothing this name is just a name and I hope that each of you will see a technology behind this name and not only name so we started to develop cocaine at Yandex two years ago to solve problem with unifying our infrastructure as some of you could know Yandex is quite large company and there are about hundreds of different projects in Yandex so it's easy hard to it's quite hard sorry to maintain this project so we started to do this awesome thing so five minutes not enough to describe you to introduce your all features of our platform so I tried to introduce most important of them first of all cocaine has a pluggable architecture and each component of this platform is a plugin when it comes to storage for example it's used to store your code to save to store applications of your settings and it is provided as a service for read and write for your applications we use elliptics and if you want to use Cassandra for example you just need to implement your own plugin and after that it will work by magic and you need not change anything in your code we have automatic load balancing we use IBBS to communicate our well-known entry point to the cloud with backends we have all information about size of cues and each worker of your application in the cloud so we could spawn more workers for you if Lord is loading is growing now sorry and if there are a lot of workers in idle state we will kill for you of course we have isolation it's based on Docker technology thanks for Docker team for that awesome thing we support any language of course but we have frameworks only for seven languages Python C++ core Rabi, Perl, Java and not JS sorry for the last and it's easy to write your own framework framework implements IO between query of platform and your worker and for example Python framework is written pure Python and it's easy to maintain it's easy to explain to somebody and it's easy to understood and it's really necessary to write frameworks pure language flexible protocol we don't use HTTP in our platform we have our own protocol it supports streaming multi it looks like HTTP 2.0 and it allows you to communicate between your applications in the cloud and for example if you have a huge monster big application you could divide it into parts and after that communicate between them without reinventing communication system so the bottom line is if you need your own infrastructure if you need your own private cloud you should take a look at this project and I'm glad to ask or sorry I'm glad to answer any questions about that thank you thank you so much we need Lucas Bednar on the stage and we have the first crowd source choke knock knock race condition who's there that brings me is Lucas here Lucas knock knock get to the stage there are only two hard things in computer science cash invalidation naming things and off by one errors now enough with the jokes I wanted to try something different no no no no no no no no it's shamelessly stolen from Bobby McFerrin and he was telling the story that it worked in every culture so I was thinking will it work in programmer culture I have to test it and thank you so much for being part of it you remember Pavlov being in a bar the door bell rings and he says oh shit I forgot to feed the dogs black screen I remember the blue screens that was my first deployed largely deployed application the customer just deployed some spare server standing around and regularly it was a virtual machine running on faulty memory chips with a wrong driver and I was deploying it with PostgreSQL 8.0 beta 3 and it crashed every day the server not PostgreSQL and I didn't know it it took something like two weeks until somebody called me oh it's wrong we need the next one it's harder to find Vlad and Zalin Vlad you're here and he's got a Macintosh so that's a 201 you know none one so it took two weeks or three weeks until somebody reached me by phone and told me oh the application is not working can you take care of it I try to log on the server and to know well I reached a system administrator and he told me oh if I would always call you when a server blue screens you would have a bad time and there was running a better version of PostgreSQL which nowadays is discontinued because it's unsupportable but it never lost any data and what did Vlad and Kali in at EuroPython give him a big hand for a story and don't start yet I need Abraham Martin to move to the stage very good now you can start okay hi I'm Kali there is Vlad my colleague and friend and I'm going to talk about what we did that EuroPython it starts at the party like everything starts at the party but there we kind of did the party of our own and at that party we reversed the APIs and created Zippa which are the APIs reversed and they are it's a package for magic Pythonic REST clients and I'm going to finish with the buzzwords right now so what you can do for start you can import from Zippa any kind of client REST client you want like here I'm importing the GitHub API under the hood it magically transforms your import into a client it translate that API dash github dash com into API dot github dot com and you can do you can get resources like this very simple it translates gh dot user into slash user automatically and you can print the login name or do whatever you want with it you can easily create and delete stuff like an August what's the most awesome feature it supports simple iterators you can iterate throughout the resource and it follows the link header and actually iterates through the entire collection and it also supports filtering those iterators so you can iterate through all Django repositories sorted by creation orders by their creation order everything it does it's not hard coded into the client so it's a general purpose what in this example it's not that we implemented the GitHub client we just used Zippa to create a github client so where to use it you can use it to quickly access any API without a native client given that that API is written restfully and also to test your own APIs or if you want to develop an API and you don't want to write the client you can just give Zippa as a client and that's it we want to thank Claudia Poppa, Daniel Hayler which contributed already to this project and also the hacker fleet we just launched the pip package from the boat yesterday and you can join us tomorrow we want to make it pass the Python 3 test right now works only on Python 2 and we also need to write documentation and examples and that's it thank you please set up I need Pablo Zelais and Celia Quintas or Zintas to come to the stage can you make you show yourself so I know you're moving and the first crowd show crowd source choke was by Emil Stenquist and that was a race condition and I got a follow-up joke which was linked to an external website clickbait in jokes contribution you can't believe it so that joke is a broad grammar has one problem he thinks oh I will solve it with threads now two has problems now four men client okay hello everyone and sorry for problems first it's Lukas that's a race condition absolutely we we using threads here Lukas the foreman client your stage okay hello again and my name is Lukas Bednar and I work for FMQE infrastructure department and I would like to say something about the foreman client I'm not I'm not sure if you everybody is familiar with the foreman this is actually what they say about themselves it's a complete life cycle management tool for physical and virtual servers what what actually does it mean it's it takes care about provisioning machine configuration machine and also it monitors your machines it is able to manage many services like the FTP server DNS DHCP puppet master BMC BMC it's some kind of encapsulation of power management that means you don't need to care about if it's a bare metal machine or virtual machine if it's controlled by open-stack or whatever we just want to proceed with power cycle and that's it here's just a small list of supported computer resources of course bare metal open-stack of it is easy to and more the most important thing for automation purposes is it has a rest API so we can script everything so let's find suitable vapor for the Python but unfortunately there was nothing so no problem we can write it and share it it wasn't so hard you know it's just a weapon in the request to the APIs and here it is but for men is quite young project and it is under fast development so the API is changing logical structure there are new version of the API so we had to introduce a lot of logic into it and it got the quite complex and hard maintainable also no schema available so it was the problem so I we just got rid got sick of it and said stop and we just took look and there it was the good documentation which was also generated from the API so let's look at it look at it here is the HTML form it per its tells you everything about the all methods you can call also the parameters and so on and also it provides you in the JSON format so that's that's actually let's generate both client on the fire from the documentation and it worked actually we implemented it for a version a version one but we got it for free also for version two because we auto-generated it from the documentation or once we generated from the documentation it also has documentation included inside of the module automatically because we have all documentation you know there if you want if you're interested or you need to manage your infrastructure by four men you can fork this project and and play it with it but I have second thing why I'm talking about because yesterday I attended the presentation about elastic search clients and actually they did the same they followed the same pattern you know I was considering that like the crazy idea to generate the API from the documentation but apparently I am I'm not alone who wanted who just did the same also the risk order but I was trying to use that but it wasn't compatible with the format documentation so so that's it so I think it's interested idea to to try write some kind of clients driven by AP documentation it improves the documentation of the API and it's it's fun thank you and if you want use it then now Abraham are you are you Abraham very good here's Abraham I have to thank Patrick for the threats joke and another crowd sourcing joke from Uwe what's the favorite activity of bits no they drive on the bus so if you have other crowd sourcing jokes and sources jokes about crowdsourcing you can send them to jokes at lightningtalkman.com you can also send jokes that are not about crowdsourcing I'm crowdsourcing jokes to jokes at lightningtalkman.com and I'm very happy I want to have it in a clear type thing Abraham Martin of the University of Cambridge will talk about HSTS give him a big hand and start hello how many of you are using HSTS well only a few ten as much so but how many of you know about HSTS okay so the same hands so HSTS is basically HSTS is an RCC which is really well it's pretty new because RCCs you know take a lot of time to be approved and to be practical to be in a final product so basically HSTS solves the following problem let's say we have a we are browsing our bank web page and we type bank.com which HTTP and we get a response from the bank web page where it shows the welcome page in HTTP and it has a button that follows the link to the secure login using HTTPS and also sometimes they also send us cookies or session with session content inside basically when we click the login button we are redirected using our browser to an HTTPS secure login in our bank web page but imagine you are in an insecure place for example the Euro Python where anyone can just create an access point and you maybe doesn't notice and you connect to it and it can act as a man in the middle with doing the network connection and you so you send the same request bank.com and instead of what they copy the same web page the same you the same web page but with a little change in the URL so you end up connecting securely to this different web page because it still has a certificate which is valid but with a different typo some well most of the users doesn't check if the there is a green lock or even an extended certificate which also says the company name in this case PayPal so most users will notice that they have changed the URL and they are now in an unsecured web page that is fake and even when you start an HTTP connection you end up sending the well the web server may end up sending the session cookie and all the cookies through HTTP although you later connect to them using HTTPS so you could think okay I'm safe because I have my web server which uses redirect all the HTTP calls to HTTPS but if you have money in the middle and you send the same request the money in the middle also can send you an HTTP redirect to a different a different URL and you will notice so at the end do you have this configuration but the money in the middle does the same thing and we have the same problem at as the beginning so it doesn't solve the problem so we have the HTTP a strict transport security to the rescue and basically what it does is the first time we visit the web page we send the request and then we get back the web page plus a header that it's called a strict transport security so the browser learns that this web page from now on use it should be accessed using HTTPS only so you any other request that you send it will transform to an HTTPS connection the same goes for if you have your configuration as a redirection it doesn't matter if you first serve an HTTP web page and then you redirect to an HTTPS or you do it using your web config your web server configuration so the next time the user tries to go to bank.com using HTTP or rather as most of us does without putting HTTP or HTTPS the browser knows that this web page is in this secure list and doesn't allow you to do a request using HTTP but instead it changes the URL to HTTPS so it's impossible for a man in the middle to have this connection and redirect you to another URL and it's really really easy you only have to include this on your app as a configuration and also it's almost compatible with all the web browsers so please keep your users safe. Very exact timing Abraham. That's very important for browser security to have exact timing. We need Pablo, Pablo, Zedais and Celia, Zintas, Kintas I've got the Latin pronunciation to the stage and I need Yves, Yves Hilbisch. Yves are you here? Are you crashing another economy with some hedge funding? No as we are talking about banks do you remember that ATM who was addicted to money? He suffered from withdrawals. Okay that worked well. Now our next speakers will be Celia and Pablo about the PyArgentina community. You look quite ready and now you're pulling back. Give him a hand until he's ready. Okay this is my first time here in Europe Python I think for Celia as well. Second one but it's the first time we're going to talk a bit about what the Argentinian community in Python is doing. So it's a bit of a lot so we're gonna be quick. So well to use a bit of enterprise philosophy we have a mission and vision to integrate like the Argentinian Python users to share experiences and to spread the Pythonic word like among developers also in companies universities are more important like to foster and create like a very active community. Also like the Python Argentinian community is the point of reference for Python use and distribution and okay we have a lot of activities like the community has been growing steadily like we've reached like a thousand and three hundred members only on the mailing list very active by the way like more than 400 messages per month we have a lot of a lot of members not only for from Argentina but also from other Spanish speaking countries even from Cuba it's not on the map but there's a Cuban guy I'm working with him and okay we have also very active IRC channel I don't know why but the most active members call it the channel of love you gotta ask them and we have a very active also web portal and just a minute okay a very regular meetings all over the country like most of the times in Buenos Aires but all over great chance to meet to face face to face to grab some beers and talk about the future of Python and the world okay let's go to the event like this is the event I like the most are the pycams we also have conferences but this is the the one I like the most like it's just it's like a four-day sprint there are also like sort of like lightning talks and a lot of projects people from very different backgrounds like I don't know on the last one we saw like a 40 year old Googler explaining very basic software an 18 year old newbie and a lot of like very interesting products have emerged from this could maybe some of you if you work the mobile you know cocos to the and okay now let's move on to the we have done six already we also the community also translated the official Python tutorial to to Spanish and it's available in printed and PDF versions it's being actively delivered to universities and schools and we have a couple of conferences like since 2009 we have a pycams every time in a different city like Argentina is very centralized and we try to fight this by organizing in different cities next one is going to be in October in Rafaela and we also have a lot of local events like Pi Days which with shorter and quicker talks but a lot of them and with a main focus on introductory topics okay and now to use the last two minutes Celia is going to talk a bit about another conference okay I'm the side by part of the of the group we make the past year the first site by calling Argentina we make it in Patagonia we have three two trainings several talks international keynotes with Bravo from Machavi development we have also a parallel workshop of robot programming for high school students we have 200 participants and 60 students working with the my with robots and Python the next one is in October in a few weeks is going to be open to poster and submission and it's going to be in by a blanket close to Buenos Aires also this year we have a pilot this group that are already working with us in the sci-fi conference organization and they have in a lot of meetups in the Django girls so this is where can we find us and thank you very much thank you so much this month brings a lot of good news from South America first we win the World Cup and then you tell us about a great community yeah and we have we have a short question what is the best way to divide eight eight seven and one okay another crowd so joke by Morton Preckig volt an SQL statement walks into a bar he sees two tables and asked may I join you I'll use that again at PG conf Europe I need Erica Erica on the stage and our next speaker if you wish the Python once about oh Python quant platform I was reading PQ as a Python Q platform so give him a weekend for the Python quant platform if you wish well thank you some of you might know me and if you know me you know that I'm doing fight finance mainly with Python actually so this is about a project that we started recently is very nascent but I just want to demonstrate what we've been doing so far as well we're based financial engineering with Python something we do since quite a while but now we're trying to unify and yeah to bring it on a single platform it has collaborative features it scales it yeah it is for individuals teams and companies many for all those who are doing quant finance actually the analytical core components are many comprised of the things that we've been doing since years at now we started decision what you see in the left-hand side of the slide a couple of years ago I think six years ago DX analytics kind of a recent thing that we did and we now using I Python and all the things that the wonderful Python world offers us to integrate this on a platform actually I mean it's powered by a full-fledged Python stack anaconda I don't know if you're using anaconda but if you're not just give it a try as a wonderful distribution by continuing analytics all the folks from continue our round you have to try it we love it you should love it as well so give it a try I've been written this book Python for finance for people who want to use Python in the finance space but still there are a couple of hurdles to take and what we want to do with the platform is kind of to make it as simple as possible to implement financial workflows and applications by using Python the project currently uses a standard Linux server there's nothing special about that Python for anything in the back end and jQuery in the front end the status is we're only eight weeks in so it's pre-alpha we use it internally for example for training is pretty good and what we have achieved so far that we have integrated ipython notebook and the shell we have a file management with power base shell access to the server which you can use for women editing I will show this in a second kid integration with a chat room user administration under the hood and this what we've been focusing on actually that we started building it from bottom up actually using Linux and everything about rights and roles and group management and so forth to have kind of a collaborative scalable environment but let me come to the brief demonstration this is how it looks like maybe I should do it a little bit oh it doesn't show on the left-hand side unfortunately is it my fault yes lots of stuff missing ah here we go perfect thank you I don't know if I was that so you see we have been writing a rapper around the ipython but I would show this in a second we have file upload a file management system we can upload we can download stuff for example I can navigate the platform here for example to the public folder someone else has done obviously an untitled notebook in here I could maybe try to delete this in a second yes I really want to do oh well this is not your notebook you're not allowed to delete that so it's pretty safe to share stuff and you can be sure that you and only you are allowed to change or to delete stuff that you've been providing on the platform so we have this complete user management and rights and roles stuff in there you see the shell integration here we can of course run ipython shell in there I kind of editing on the server so this is a file from the server where the women editor open to edit the file but of course you can edit any other file you can have the python shell of course again the hello your python simple example and you see it's all anaconda powered and it's based on redhead linux server so again nothing special about that but try it out anaconda and I think the main thing where people are using right now in the world is the ipython notebook if I fire this up and you see I can change a little bit the thing that we have a full workspace takes maybe a second to load it I don't know I'm gonna do it again I don't know I did it a couple of times before there's always when you do a live demo actually so don't use this tool for a second trading here for example I see another one which opens immediately I don't know what this isn't firing up if the analytics one you see here of course you can do all the things that they used to do and with an ipython here we're using our proprietary analytic stuff for example do complex derivatives analytics here for multi-risk derivative which is pretty hard to value and see we can even do numerical stuff which is very compute intensive and all the things the last thing I want to show it's actually really the last thing so we're something like a chat room where you can chat with people with colleagues you can upload files for example we have included something that you have little profiles a little bit of internal social network and what we also have implemented is that you can upload for example research paper or whatever and you can share with the colleagues have a look at the PDF file this is very interesting a new publishing publication which might be of interest for what we are doing so if you're interested in that actually it's pre alpha as I said but what we have done is a a simple landing page you can go to quant quant dash platform.com and there on the platform you can register if we're interested in it while Erica is setting up to talk about code week in Europe I need a Remco event Remco are you here can you move yeah and be prepared very good as we were talking about database jokes we were very happy that the British Met Office moved all its stuff to PostgreSQL because it's a great database and I love it on the other hand I'm not really sure why the British meteorological office really needs a database to forecast the weather now we'll have Erica and she will be speaking about the code week in Europe give her a big hand I made sure that I'm a first-name basis with her because I would not dare to pronounce your last name Erica so yeah hi I'm Erica I'm not Erica Erica I'm Erica Pogorel this is how I pronounced my last name and I want to talk to you today a little bit about me is my second time at Europe part Python and I work with peer-to-peer University we are distributed team so we don't have an office and we're all about peer learning so what I do that there is I help people I help I build tools to for people to actually be able to learn from each other to teach each other and stuff like that and I use Python all the time which is cool so one good project that we have is a project called mechanical MOOC which is a kind of a platform that we use and one of the content that we have one of the courses that we have is gentle introduction to Python so this might be a hint for you if you need to build a community you're in your local space and you know to learn Python and this is essentially an experimental MOOC which means that it's headless so there is no a centered Instructure there really you know so people are just what we did with with we grouped the cohorts locally and now that people are learning from each other and teach each other and all we do is fire up an email once a week you know to suggest the topic that they should learn about to progress slowly so another good actually another good project that we are doing is play with your music and this is actually a collaboration between New York University peer-to-peer University MIT Media Lab and Peter Gabriel he was actually kind enough to provide us with all the materials that learners can actually build upon they can reverse engineer them and you know he's even included in the process of learning with interviews and stuff like that and we were really grateful that he provided us with that because that really eases up the tension in the copyright sphere so since we already know now that we are quite musical we can sign up for that course too and this is my afternoon project my co-cat's project this is a group of young women and men mostly women because our one rule is that there has to be more women than men but we are learning to code you know and we don't have a sponsor and that we are searching for one right now but it would be nice to have some so the aim is to show these people that want to know about our work process process and the aim is to show them how a simple app can actually come to production so how do you start it and everything else and we meet every week without exception because we believe that you know you have to be very consistent with learning so we did something very special this year European Commission actually trusted with with a task to enable people to participate in a code we key you this is a thing a very simple Django app we decided that we are gonna put our code kittens which are you know people who are actually not that they don't know about programming that much they will actually build it and they did and first they did a mock-up you know to demonstrate how it will work or how it will look like and then they researched about tools and they decided to use Django because it has already built in a lot of stuff and we decided to give them the deadline you know so which made them really kick up a year and they all of a sudden suddenly everybody was finding more time to learn which was great and it turns out that the if we let them go through the turmoil of maintaining their own code they actually learn a lot you know because now after six months they actually know where did they write the spaghetti code and stuff like that and you know from ourselves or from themselves and each other and which is good so that they decided that they will have a reflected long this is something we're factoring is like a hackathon and we already have 300 events so if you want to help with that it's like you can go and you can try to break our app and put an issue and get help and we're going to be very happy about that so and I just want to quickly say what what a code week is this is a week which is dedicated it's happening in October and it's dedicated to coding so we are celebrating coding and it aims to get more people excited about coding so if you have a meetup or a coding club that meets meets that week please add it to our nice build app and join us at the code week thanks thank you very good now I need Ramco when to prepare and Christian Tisma Chris are you here start walking to a stage where you are next now you have no slides so you can start immediately slides very good very good now give Ramco when the big hands for being without slides totally prepared about our beautiful minds so first of all can I ask all of you just for five minutes very humbly to close your laptops put away your mobile and just be here for the moment so I'm Ramco this is Ludwig I met Ludwig on Wednesday and I was telling him that I was going to give a lightning talk and then he told me yeah I really want to have some more podium experience in the future and I said okay why don't you join me on the podium I'll do the talking but in the meantime you get some proper podium experience give a hand to Ludwig because because from here on really for him it will be a much easier step to giving an actual lightning talk and that's what we want in the community so I hope I can take these five minutes or four and a half to put some interesting thoughts into your beautiful minds that's also why I call this presentation beautiful minds it's you I was walking around in the Spanish desert near Zaragoza a couple of weeks ago and basically for a little while I've been thinking about what will be my next thing my next business or venture however you call it and then it sort of was like maybe I should change the world and make it get a little bit better better than the way I found it in and that's what my talk is going to be about because then I came to Europe Python and it all made sense so how does one change the world it never starts with big big ideas it starts with big ideas but it's always the small things that matter we know this from peer to peer it's like small individually decentralized elements you put them into play but their volume makes it work so first of all what I want to what I want for you to realize is that we're not mere developers we are the engineers building the future of tomorrow we have with what we do combined our combined effort we have such an impact in what people do in tomorrow's technology this is really something that comes that gives us great power but also comes with great responsibility and it's just really do we as a community want our future to be about control or to be about freedom interesting to think about so we have quite a unique position in this and the unique position is I've had a few companies before this and whenever I was hiring tech people they didn't really care about the money I mean in the end they did care about the money they need to have it covered but the funny thing is that I think most of you hear it's like yeah money income we have it covered so the questions you get as an employer is not like how much money I make but it's more like how much time do I get to invest in myself and how much of my time can I for example contribute to the community to code I want to give away to helping people with making documentation all that kind of stuff so actually it's pretty interesting because what this signifies is that we are taking a step up in the muscle of pyramid where you have this income thing somewhere in the middle and if you have that covered it grants you a lot of freedom and what happens then as people start teaching I mean I've been involved as a volunteer here with the open tech school in Berlin and people come together it's like yeah we have some time and we like to teach other people so that's what they do and they ask nothing in return but they get a lot in return because I think fundamentally our genetic code is made up in such a way that we care about ourselves first but then we care about the others so it's really fundamentally what we are and fundamentally part of our happiness how much we can help the other and this community has such freedoms in doing this it is amazing to realize I think that most people and maybe you don't realize it yourself yet but unless the world economy is going to collapse we have great freedom we have income stability we have it covered so from here I think what is interesting is however beautiful things we're doing within the community is maybe also think a bit more about how to step outside of the community and how to bring these values outside to other people and it's an interesting example today I just moved into a new apartment and it's inside an alley this is the one minute thing oh the last sentencing uh okay think about this if you want to hear more look uh search me out I'll tell you the entire story thank you thank you Ramco Wendt now the first good news we finished the regular lightning talk list and we are going on to overflow number one Staglis by Christian Tismar and I need David Moore David Moore like M-O-H-R are you here please prepare to come to the stage our next speaker Christian Tismar a long time about Staglis best ever forever give him a big hand thank you very much I will be very quick and leave some time for the others who come after me I just want to motivate everybody you should try out Staglis formally Staglis python because it has become so much better very compatible you got binary installers which are working on OS 10 or windows they are compatible they run with with the existing packages and other binary installers together you can just put it in replace your c python keep all all extensions inside or undo that again it's just fun to do that you got great debugger support uh the debuggers like the the professional ring IDE py charm and py def they are all supporting Staglis so uh binary compatible extensions which are most important as uh py qt and py side and they work great and uh so just try it out install py side for instance we have a pip installer which does that with with binary wheels so you can try everything in in half a minute okay then you can run the py side demos and I wanted to tell a lot more but I had not enough time to finish my slides so the rest comes tomorrow on this print see you thank you very much 15 times Staglis as ever our next speaker David Moore please set up and Philip power Philip can you make yourself visible he is here move to the stage our next speaker David Moore will talk about stellar compiling a small subset of python and why he's setting up I've got something for you what do you get if you cross a historical question and a joke so if you like better jokes just mail them to me okay you're good with setting up Schrödinger and Heisenberg will be the next joke which you can hear on another conference now it's David Moore give him a big hand about stellar hi everyone I'm David Moore I'm currently studying at the University of New Mexico in Albuquerque USA and I'm going to talk to you a little bit about this project I'm working on and I'm going to try to compile a small subset of python uh so essentially where I'm coming from is we all know python is fast enough and that is a mantra I'm not disagreeing with but uh unfortunately doesn't work for the stuff that I want to do um and eventually you know it's just getting tired to having to you know rewrite your stuff in C because you need performance and I like python it works for everything else so why can't I stick to that uh so a little bit of background about where I'm coming from is uh we're working on stochastic simulations uh kinetic Monte Carlo simulations which are in itself very very basic but you need lots and lots and lots of trajectories so in the end it's very very time consuming to to collect that data uh and the code is a little bit special uh in that it's not like the whole simulation is important there is no 80 20 distribution uh they don't work with arrays you don't have differential equations to solve so a lot of the tools that are highly optimized for python don't actually work in this situation um and another important part is that you you get a lot of variants basically a lot of different kind of programs that basically do the same stuff but here and there they vary so that's a problem of course that's been around for forever and we all know how to solve it it's usually with object oriented programming so you know when we try to speed the stuff up there's a lot of tools and you know I tried them all and unfortunately they don't work very well for me and I think that's because they have tiny little bit different use cases um in particular with them they all strive for be most inclusive you know have being able to use python as easily as possible uh when the language itself doesn't have the accelerated feature uh but for the simulations what you actually want is you want to guarantee that everything runs quickly um so you don't want integration you just don't want to have to deal with python at that level because it's too slow so what I want to do is uh create a domain specific language which actually just is a little subset of python um you know throw out the stuff that is not necessarily required to write a simulation no dynamic features statically typed and then implement it as library uh and support at least a little bit of oh so that I can nicely structure my code but I don't have to worry about like all the fancy features which are actually expensive and difficult to implement um so there's my the approach that I'm taking with this is uh actually work with a python byte code so I get a lot of stuff for free that python already does with the source code you could potentially use multiple inheritance all that kind of stuff to get to the result that you then want to run and then just transform it to lvm intermediate and yeah just run it because at that point when you're doing an ad runtime we have type information and actually I can study I can infer all the types execute it return the data back to python and be very happy um so yeah this is actually just a quick overview I don't have any code to present yet because it needs a little bit of cleanup before I can you know let other people look at it uh but it's going to be ready to share soon and I would love to get some feedback if anyone's around on the weekend thank you we have two minutes more for a final late lightning talk by Philipp Bauer Mozaik please set up your computer fast I've got another crowdsourced joke from Alex Wilmer a python walks into the bar the bartender asks the python how did you do that you don't have legs so it must have wiggled into the bar um german conference regulations make it clear that we will have to have a coffee break at half past three so this is so this is our final lightning talk I just want to tell you a little about some of the features we're planning for the future of plone this is work done at the plone Mozaik sprint in Barcelona earlier this year and since I can't type fast enough I'm going to show you a pre-recorded screencast that I actually didn't do myself so here it is uh this is about uh custom custom layouts and a layout editor called the Mozaik layer uh editor where which allows you to create content which uh asco suga who made the screencast uh creates here uh using the latest plone version not plone five like five future in autumn uh store this uh theme this is the uh Mozaik theme editor uh adding a field that was pre-added to the content and adding now static text fields that will be stored on the instance and the theme pretty intuitive this is a rich text editor and uh the the layouts you can create with this can be reused either on specific content or whole sections in the site and they allow you to create uh say landing pages or specific site layouts that you can always use with specific content types I'm gonna skip this part because it's a little boring which shows you that you actually can save uh that uh that layout on say a event so events have a new layout so you don't have to program your view in an editor but you just drag and drop the fields wherever you want them set these uh stored views as default views for the instances and there you go uh the second feature is um okay I was too fast I can't remember the type of themed layouts yeah so here we are creating a new content type with dexterity uh which has the layout support enabled so this is a default feature of Plone we create a new content type it's a schema it's a folder has the layout feature and navigation route and this allows you to have a sub site in your Plone site that has its own theme so here we add a new uh object an instance which is the sub site with the uh already enabled editor uh the music editor now we copy content from the default Plone site to this new uh container that we added and here we set a theme which is a bootstrap theme now and now we edit that bootstrap theme with the music editor and add static and dynamic content to that and all the content that we copy to is there and also uses the same theme so these the theme is inherited and can be overwritten by different uh items this is another theme built in and you see you can pretty easily edit content this is kind of the future of content layout prototype editing uh which you can actually really give um your content editors um I'm gonna finish here so yeah I think that's pretty awesome this will land in Plone 5.x I guess 5.5, 5.1, 5.2 uh sometime next year we're really actively working on it and there's a product called the inter uh Plone intranet product uh which will rely on this technology heavily in the future and um just one more thing uh Nate's just created a option to have free like zero euros clone hosting on Heroku we will uh announce that after the sprint thank you thank you very much now that concludes the final lightning talks we just ran over four minutes into the break we'll have a coffee break that's 26 minutes until four o'clock then the closing will be here so please again give a big hand to all the speakers and the audience thank you for enjoying the lightning talks have a great time be back at four o'clock for the closing of the conference
