This is a list of some posts and talks I have read and watch during the last days. I write it to keep track of interesting content for myself, but you might also find it useful.
Jon Sneyers from Cloudinary posted Detecting the psychovisual impact of compression related artifacts using SSIMULACRA. It talks about SSIM (which I have covered in the past), used to compress images based as much as possible without affecting the visual appearance (no visible artifacts). Jon describes Cloudinary’s SSIMULACRA and benchmarks it agains the top perceptual metrics.
Tech companies: these are the perks (and benefits) I want. I agree with Tara’s points about what I find important in my job and hope more companies embrace them.
- Cloudinary released their Website Speed Test Image Analysis Tool, which is also integrated with WebPagetest.

- Nic Jansma and Shubhie Panicker gave a talk at Fluent Conf named “Reliably Measuring Responsiveness in the Wild”. The slides for the talk are already available. They are full with great insights and are a must if you are into web performance. They show how to on measure responsiveness using old and new Browser APIs like PerformanceObserver, and show examples from real sites and how these metrics affect conversion rates.

I’m from Alicante, Spain, and I was very happy to find out about React Alicante 2017. There are not many tech conferences in the area, and I hope it is a success. Unfortunately I won’t be able to attend, but i¡ll keep a close eye on it.
