The BasicsBuild a Progressive Web App In #vuejs, from Zero to Hero!The concept of Progressive Web Apps (PWAs) is a framework agnostic approach which seeks to combine discoverability and accessibility of a website with the functionality of a native app.Since couple of years I see an increasing interest technologies which bridge the gap between web- and native-apps.In 2018 PWAs have made a great step towards mainstream adoption. By now, plenty of companies like Pinterest, Uber, Twitter, Trivago, The Washington Post, Starbucks, have already created PWAs to run parallel to their native apps.The reason is obvious, plenty of these companies report very promising numbers, mostly as astonishing as the 97 percent of increase in conversions Trivago has seen.Why should we start developing PWAs now?In (...)

How Artists Can Set Up Their Own Neural Network — Part 3 — Image GenerationAlright, so we’ve installed linux and the neural network now it’s time to actually run it!First though I want to apologize for the delay in getting these last two parts of the #tutorial series out. As I explained in my Skonk Works post, I’ve been learning so fast that it’s actually been kind of hard to catch time to digest and write any of it down.For instance, this tutorial series began with teaching you how to install Ubuntu 16.04, but support for Ubuntu 16.04 has just ended and you really should install Ubuntu 18.04, which is what I did after wiping my desktop and turning it into a fulltime personal cloud server! This is good because now I have a completely dedicated Linux machine to run neural network batch jobs on (...)

Apprendre caméra en main - Les Cahiers pédagogiques
▻http://www.cahiers-pedagogiques.com/Apprendre-camera-en-main
Comme toujours, des membres de #Seenthis à l’honneur, le réseau social le mieux fréquenté du monde.

La dimension collective et l’ouverture se vivent également au travers d’un projet #tutorat mené avec la classe de CP de l’école primaire voisine et son enseignant, Emmanuel Veneau. L’#école est située au cœur du Garros, quartier classé prioritaire où habitent un grand nombre de familles défavorisées, avec cette particularité de se situer dans un environnement à dominante rurale. Les enfants ont du mal à se projeter dans un avenir scolaire au long cours, voient le lycée voisin comme un espace inaccessible, à la limite de l’interdit. Les lycéens de leur côté vont très peu dans le quartier. Au-delà de la différence d’âge, le projet associe deux univers proches géographiquement et pourtant étrangers.

Les professeurs imaginent la création « d’une sorte de chaîne verticale de transmission » propre à ouvrir les frontières invisibles. Le travail de collaboration se déroule tout au long de l’année. Il commence par l’accueil de la classe de CP au lycée. « C’est un moment fort et drôle avec la venue de jeunes enfants. Il y a une certaine attente de l’équipe éducative et des élèves car les visites se font depuis quelques années. » Les lycéens de la spécialité cinéma effectuent la visite et préparent une projection pour montrer aux enfants différentes formes filmiques. Ils ont reçu auparavant une formation sur l’animation de séances auprès des petits par le partenaire culturel Ciné 32 qui assure des interventions en milieu scolaire.

#OpenStreetMap #Carto is the style used for the Standard tile layer of OpenStreetMap.

This independent site includes unofficial #tutorials to set-up a development environment of OpenStreetMap Carto and to manage this software. It will allow exploiting the style and also being able to contribute to the developments.

To implement this site I kept track of technical notes that have been useful to me and that I hope will also be of help to master OpenStreetMap Carto fast, learning all most relevant aspects from the ground up.

Let me set the stage: you’ve come up with a great idea for a web app, and you’ve decided to build it with React. By way of completely arbitrary example, let’s say it’s a guitar chord finder with an interactive guitar neck and a submission form (like, say, this one).Shameless self-promotion!You’ve made a couple to-do lists, watched a couple tutorials, and you think you’ve got the hang of all this “props” stuff, so you jump right in. It’s going well enough — you’ve got your top level app component, maybe a form, a guitar component… and then, it starts to dawn on you. You’re going to need a guitar… with six strings… with twelve frets each… which all need to communicate information about whether or not they’re muted, pressed, or open…which need to be able to communicate with the form and express a chord… (...)

I received the following email a few days ago:Jeff,It seems that you know about iterators. Maybe you can explain some weird behavior. If you run the code below you will find that the function is treated differently just because it has a ‘yield’ in it somewhere, even if it’s completely unreachable.def func(): print("> Why doesn’t this line print?") exit() # Within this function, nothing should matter after this point. The program should exit yield "> The exit line above will exit ONLY if you comment out this line."x = func()print(x)When I run the code, I get the following output from the print() call: <generator object func at 0x10e968a50>.So what’s going on here?

All it took was this simple weekly approach and patience.Building and promoting a new consumer product is one of the most challenging things you can do as an entrepreneur. While there are many approaches on how to design, test, build and promote apps, usually they don’t seem to bring real results.Then you start wondering, maybe it’s the product? Maybe there’s not enough market feat? Or is it bad execution? Or maybe we should grow the marketing and branding budget! Maybe we’re not targeting the right audience? Maybe we should build more features!When you start questioning everything, things usually get even worse. You start defocusing from the main goal and start wasting energy and money on all kinds of wide approaches.The worst is when you think it’s all a matter of growing your marketing (...)

Build your Logistic Regression model from scratchLogistic regression is the most famous machine learning algorithm after linear regression. In a lot of ways, linear regression and logistic regression are similar. But, the biggest difference lies in what they are used for. Linear regression algorithms are used to predict/forecast values but logistic regression is used for classification tasks. If you are shaky on the concepts of linear regression, check this out. There are many classification tasks done routinely by people. For example, classifying whether an email is a spam or not, classifying whether a tumour is malignant or benign, classifying whether a website is fraudulent or not, etc. These are typical examples where machine learning algorithms can make our lives a lot easier.
