thank you all you need 1 and in the book good other good online repeat 6 subjectivity slower the clearly on the so downloadable by applying the future of the Python system is is general you're talking about I would say it's my perfect future work like those in common everywhere of so
we can find him social
structure of and of all so on related areas of largest were higher in all of its to people who are used to to show of have you by contributor all 4 years I think I've worked on the 1st thing I worked on some of the some of the project which was safe and back and forth like what was failure 1 which doesn't mean that it's impossible to save and waiting for that particular was good it was also member 5 I was to work on them by links to the community so that was really of its center thank you community and I have a the project from the middle of the you might not work what climatologists is issued standard candles and so the start talking to the implementations of norm of life and so we don't want to throw libraries and language features so that's bigger snapshot of the current situation so basically everybody uses the of books about Canada quite a few deficiencies of but performance is 1 must of efficiency and reduce also were very interested in this world of the efficiency of our and but by a few people it's quite quite on library has great performance and serious getting there so that's good and according to the case that's the place of the following conditions are all of the news like hundreds of models agreements or something like that so let's make it quick all right arm was used survive before and was used by by those that typing by buying the criteria and was used so far I would like so think in almost all the languages we have 1st language is that well designed to be the 1st line of Javascript on pitch and the 1st 9 all those those of all the languages that grew to become have a given getting used and language work to really as well so for example PhD wasn't designed for for performance and they managed to have all good performance with our children which Facebook users other people let me see if we can do it we can do it so it that's what this is about life on because th or even like just the use of fast just food and things these days and so what a culture displayed today and it's pretty hard to switch between implementation of you have of 6 sentences and sentence of whatever and all so why can't we consider 6 instances they come from the somehow on the continent in the areas of and what will be the distance the rest what basically so implementations by the way what most extensions of trade you can use some of them so is if you we should treat like Python consisting of like that market you would say that like this extensions of it's current market theory so basically you survive use extensions and then on and a lot of competition would bring it everybody on their like it's something tomorrow bits by like I'm not gonna come in and like and news also something better variations of to the degree of and you basically it's all right and python implementation tomorrow that covers 100 per cent of Americans but if you don't see extensions evolve and your on implementations has to be really really attractive so let's not and so on work on just by biological neuronal firing patterns from this is the only force that even if you implement this year period it's natural because for example sigh all bypasses the runtime and groups synthesized structures and stuff like that and they have played by mode where don't do that anymore the conservation I and even human from the official the the you have to use all great reference counting of reference continues and slow and those who were not very interesting story from history here you can images having a reference counting the removing practically impossible so there was this experiment with a flat spectrum on and 1 . 1 4 it was revived by the industry a 2 years ago and yes it was much slower than regular supply so it's basically you have to choose between performance and current on 1 side and the CAPM model with is pretty so from the wonder like other languages have that's right things to all the library to see libraries right the don't it in there are like closed world use serious so my iPhone true families of CPA of the of the of the Jane and we were curious about
various modulates Jennifer moralist but based on GPS issues you want to promote talking about the use of handles which is also a set of users on and these don't make assumptions on the environment because so for example JNI I already tragedians already 1st so the superior based on the 1st and so can could we have something for all I think we can on it would stop words to to write remove all 4 of counting and stuff like that so that's not many changes look pretty massive changes for people engines mistake you can have your own CPA with certified basically so you can already do it to and it's a big political problems so good luck convincing people with math extensions to use of and yes if you if we want to build on that path would have to have between pairs and support from the people the sort of the code and I think it would be possible to like have incremental we we
and so it's a book about the war everything is about so well especially in this paper is the most flexible implementation around was mostly because it's the right and so you can search for example the garbage collector the stadium you can part of injuries on pretty quickly so I a jet of good speed of available all of which were true that it's the 1st all of which doesn't really mean anything that means that 1st order of interactive presentation of trust it would only growth and so all the logic of those from with other 1st and then everything would like to from and 1 of the principles of object is that to create good for what you use short of use by I you need 5 and has a lot of overhead if you use they implementations lexical come from that you can remove all the stuff that you don't use for example From integers objects most people cultures journals other objects with the is that much remained edges so that means that would to remove the cost of integers being object from all from transcriptions of the alright
so any In spite all we show the point of comparison so you have seen this is program written in pure python but on edge detection this is this program running on of some random view of human skin and so you can see that all these stories of somebody the negative coverage is that's not possible of so it's 0 . 4 1 this so
it's still that's what the interested on wearing that's so 258 appears light also so that the look so it is return that's how I remember all my work slow so it's 50 microns for some reason of it would be much worse for story of this and so it's a bit of a
certified mentioned there so we don't like to in Veracruz see growing problems should produce localized but it's a electrons to be able to call things that implement the CDM so most people know that most people in most of final you can call C we certified that you can also expose of Python functions to see so Jennifer CPI where you can and that by by expose functions to the world using different and it's also very very fast and part of the it's really fast and this you can do basically everything you can do with this it's like a different way of thinking but you can do the same thing other and water ice there is a progress of we're removing the kind of thinking about and they don't have to use for of President of South America so that's good you get all the hits without getting older but still yeah so as opposed to using word processing you can use our memory between words from OK I said that 1 basic concepts and this is but on the other what don't we can have so for example we could have a bridge between the basic right and then the right like this is the method I want to go do it on your own cause that's extensions of and that we could the nucleus bring the scientific study and what it would be great if we had that so
think that we have OK so implemented something confinement of analysis it's just regular by some other parts of the 1 of the properties that it's that the pretty it's about I assume it's important to point out that governments imposed on the critical value of this that is crucial to important of of and that stuff production because of so the variance of still not preclude theory doesn't work its this extension of with support and
with it's the without
and within the case where all what kind this is done over walk
around and we also have a literary all that energy is going to introduce you to use their this form the for example from about performance by we them by by Pollock similar we have examined certified which is can more recently of the summer and and so is from here and also could be due to absence of it was used by people on regularly right bindings for knowledge from the library is also very so as a summary of we can do 1 of a lot better than what we're doing right now but working on it making an antenna to implementation funded this because ecosystems pretty hard like this extension periods not really going to but at the same time it would work for a much better across the so yes thank you any
questions just 1 stupid maybe kind of that related questions because of course have so that in Python you perceive all all objects of that dereferencing claim getting absolute from objects costs something and 1 by by composites like if you have a chain of all of the references like from this object in this and this and this and then get this on the spot by by optimizing that a lot of those just do this this this the 2nd channel data the referencing by in the assembler was used in 2 differences for different on this point of what you can do much more efficiently than if you want to so in Python objects or implemented as dictionaries and survival intellectual to harsh your actually used in the computer dictionary and so on we will have the just 1 paragraphs works for 1st in and asked the so say the last slide helps needed how can we help would only or for example of right writings from your favorite libraries and set the example but when I all yeah bringing more libraries and law and the body chantries the thing that's like you will have to be afraid exposed of to so but differently the best way hundreds supposed see is compatible with life right so what's the catch of certified extensions so if it's not so great it allows you to do so many stumbling using the every everybody's fitting given by from stopping the associated or the laws of probability I know what you've already used citizens of the supervised can new so it is in lower isn't like that there is no analysis on survival and so although it's there was a status pageantry and type II approach it said 3 . 2 . 5 right now this fits well above 3 going to all the world's you already reaching 3 . 3 the during the but it's not that hard so right people can easily come and contribute so I that in making a call for people to put into place and 3 . 3 0 and we can come to this principle what would it make alone could indicate that they are alive this like fully you volunteer your project so when it's thank you they can't talk about dating could have reach like solution can work in the future will have thousands of C extensions and we can just get rid of them uh and but we would like to to migrate to buy and can mean we can we can cure migrated to if fine but it's not likely to happen this year so that's where we have heard this like it for example you can get like 90 per cent of the libraries working directly on there you won't get than the speed of something like those libraries and logical by the rest of your book with get faster because it's quite variable this is using the preference with social support from the sum of all using the bridge but if you want compatibility with its extensions right use the regions like it's ready for support for the work like you didn't always have an yes like usable looking for any of the rights of and thanks for the talk i will do your bridging oxygen like you have to interpret it to interpret as running at the same time or just you have all the it's about and I very clear and survival and they're on the same process so you can efficiently show memory from component all words it's not implemented yet but in the future of originality of past library to survive on the border between survival and very by without doing any the of the variables so that the provisions of law of the world not just the growth of the fact that of this it's in same process and and ask

Abstract Romain Guillebert - PyPy and the future of the Python ecosystem Python has a great versatile ecosystem but the competition is getting better, this talk is about how Python can keep up with these new languages and where PyPy fits into this. Recently we've seen the rise of new technologies like Go, Node.js and Julia, those have the ability to build an ecosystem on a clean slate and thus be better than Python in some aspects. What would it take to be as good as those technologies on those aspects without loosing all the things we love about Python ? This talk will describe my perfect future where Python keeps getting better, gets to keep it's great set of libraries and where PyPy fits in that future.
