Recently we polled a small group of InfoQ editors, consultants and trainers asking them for their thoughts on the state of Agile adoption and what ideas, practices or techniques are emerging or being recognised as useful at the end of 2014. This is not a scientific study, rather an informal collection of opinions.
J’ai lu voici quelques mois un billet qui s’intitule The Rise of Worse is Better par Richard P. Gabriel, développeur Lisp (qui a d’ailleurs monté une société autour de ce langage dans les années 80). Vieux billet puisqu’il date de 1989 dans sa version original. Il est, à l’origine, une section dans un essai nommé Lisp: Good News, Bad News, How to Win Big. Dans ce billet, Gabriel expose deux visions du développement logiciel qu’il appelle la conception «The Right Thing» (approche MIT) et la conception «Worse is Better» (approche Stanford).
In this book, Sanjoy Mahajan shows us that the way to master complexity is through insight rather than precision. Precision can overwhelm us with information, whereas insight connects seemingly disparate pieces of information into a simple picture. Unlike computers, humans depend on insight. Based on the author’s fifteen years of teaching at MIT, Cambridge University, and Olin College, The Art of Insight in Science and Engineering shows us how to build insight and find understanding, giving readers tools to help them solve any problem in science and engineering.
Today I watched the Google I/O presentation about HTTPS everywhere and read a couple of articles, saying that Google is going to rank sites using HTTPS higher. Apart from that, SPDY has mandatory usage of TLS, and it’s very likely the same will be true for HTTP/2. Chromium proposes marking non-HTTPS sites as non-secure. And that’s perfect. Except, it’s not very nice for small site owners. In the presentation above, the speakers say “it’s very easy” multiple times. And it is, you just have to follow a dozen checklists with a dozen items, run your site through a couple of tools and pay a CA 30 bucks per year. I have run a couple of personal sites over HTTPS (non-commercial, so using a free StatCom certificate), and I still shiver at the thought of setting up a certificate. You may say that’s because I’m an Ops newbie, but it’s just a tedious process. But let’s say every site owner will have a webmaster on contract who will renew the certificate every year. What’s the point? The talk
Creating and working with well-designed aggregates is one of the least well understood tactical patterns found in Domain-Driven Design, Vaughn Vernon explains in two articles giving some guidelines to composing aggregate boundaries and alternatives to an ORM when storing them.
Customers come to us with a new product idea and they always ask the questions - how long will it take and how much will it cost us to deliver? Reality is uncertain, yet we as software developers are expected to deliver new products with certainty. This article shows how to do planning using reference class forecasting with the #NoEstimates paradigm which promises more accuracy in forecasts.
