CSS coverage, edit local files, inline breakpoints… [Chrome DevTools]

Be careful with the Let’s Encrypt’s deployment automation

31/08/2016 / Leave a Comment

I just noticed an error that had gone unseen: this very site was serving another site’s HTTPS certificate. I started digging what had gone wrong and noticed that EFF’s Certbot had touched the Apache configurations of this site even though I deployed a cert for another site. It had overwritten the configuration and even added more lines to … [Read more…]

The problem with Let’s Encrypt (or someone’s)

21/06/2016 / Leave a Comment

Let’s Encrypt gives you free DV certificates via easy to use, automated process. Just install their script, or choose one from the gazillion of custom ones, and you’re good to go with a strong encryption to your website and automatic renewals. One thing that really bothers me when people say that Let’s Encrypt is the … [Read more…]

The day was split in two sessions (a couple of hours each) and the goal was to first touch Sonic Pi gently, then get to play with it, and … [Read more…]

Sonic Pi workshop on the horizon

22/04/2016 / 1 Comment

A year ago I saw a job offering by a wee Finnish company called Mehackit. They were offering some sort of creative technology courses for secondary schools and needed teachers. I contacted them.

I had one thought wandering in my mind during the weekend: a blog post or a beginning of a series of blog posts titled Things I learned this week. I thought about it so much, you  know the hows and ifs and whys, that in the end I didn’t do it. So here are some keywords concerning … [Read more…]

Firefox marks non-HTTPS login pages insecure

26/01/2016 / Leave a Comment

This is really great. I love it. HTTPS, bring it on! So what Mozilla is aiming to do is to ship Firefox 44 with some new security enhancements: every page, that contains a login form, but is served over plain HTTP, will be marked with the so-really-user-friendly broken padlock. You’ll get the same lock if … [Read more…]
