Jeremy nails it again with this beginner-friendly introduction to Service Workers and Progressive Web Apps. The foreword to the book says “you’ll gain a solid understanding of how to put this new technology to work for you right away” and I’d say that is very accurate.
One of the important things the book emphasizes is that any existing website can benefit from service workers, not only fancy single page apps.
I’ve been playing around with various CSS frameworks for the past eight years. All these frameworks like Foundation, Bootstrap and Blueprint have really only served one purpose for me: to disguise the fact that until now, layout in CSS has been a hack.
With this process, Kravets managed to get between 23% to 28% reduction in image size, which can add up to a lot of KB if you have many images on the page. I think this technique is a great discovery and a boost for image-heavy sites that don’t need to worry much about good IE support… but. But, I can’t help but think it does smell a bit hacky.
This kind of contrast trickery shouldn’t be done in CSS, it should be in the image format. And to be clear, I don’t mean to criticize Una’s discovery. If it’s possible to reduce contrast and then re-apply it on the fly with little perceptible loss in quality, surely those instructions could be passed along in the image files themselves and not have to rely on a separate stylesheet which may or may not load? I guess we’d need a new image format for that…
Over on Daring Fireball, John Gruber has some true words to say about those pesky floating sharing bars (or “dickbars” like he calls them) used by Medium and others.
During the years, my blog hosting has gone back and forth between a self-configured VPS and shared hosting. Thanks to a special WordCamp Europe 2015 offer, for the past couple of years I’ve been on Siteground shared hosting, which has worked fine. I certainly have no complaints: the site has been fast, setup was easy with free SSL, but… a nerd’s gotta be nerdy. As the subscription for my shared hosting was about to expire, I looked around for options, and decided to go for a small VPS on DigitalOcean for $5/month (yes that’s a referral link). One reason I chose them was their comprehensive set of tutorials, but I was still suprised how quickly and painlessly I got my virtual server set up with Ubuntu, Nginx, SSL and WordPress, in just a couple of hours. Simply by following instructions, so I can’t claim to be very clever.
Let’s see how long this lasts.
Next week, The Paciello Group is sponsoring a 24 hour live stream of webinars on Accessibility and Inclusive design for the fourth consecutive year. The videos will presumably be available on YouTube after the event too, at least I hope they will. 🙂
My main source of scientific news since childhood has gone independent. The future for the magazine looks bright I hope.
We are pleased to announce that New Scientist has been acquired by a company set up specifically to publish the magazine. This marks a return to independent ownership and operation for the first time in several decades.
I might even go back on my words in this tweet:
Come on! @newscientist you have a great digital mag, but no way to cancel except via phone?! Do you think I'll ever resubscribe?
On Tuesday, Daniel Bachhuber published a list of advanced tips on using WP-CLI. My favourites in his list are wp rewrite list --match= (for debugging rewrite rules) and --prompt (when you don’t remember the arguments). If you’re a WordPress developer and don’t know what WP-CLI is, stop everything right now and go to wp-cli.org.
Sam Biddle wrote for the Intercept on the recent WannaCry malware disaster. According to Sam, it’s not possible to name a single culprit for what happened, but militarism and greed are the two main forces at play here. This bit stood out to me:
Microsoft also did not create WannaCry. But it did create something something nearly as bad: Windows Vista, an operating system so horrendously bloated, broken, and altogether unpleasant to use that many PC users back in 2007 skipped upgrading altogether, opting instead to stick with the outdated Windows XP, a decision that has left many people on that decade-and-a-half-old operating system even today, years after Microsoft stopped updating it.
