The cloud gives us collaboration, but old-fashioned apps give us ownership. Can’t we have the best of both worlds?
We would like both the convenient cross-device access and real-time collaboration provided by cloud apps, and also the personal ownership of your own data embodied by “old-fashioned” software.
This is a very in-depth look at the mindset and the challenges involved in building truly local-first software—something that Tantek has also been thinking about.
“Serverless”, is a buzzword. We can’t seem to agree on what it actaully means, so it ends up meaning nothing at all. Much like “cloud” or “dynamic” or “synergy”. You just wait for the right time in a meeting to drop it, walk to the board and draw a Venn Diagram, and then just sit back and wait for your well-deserved promotion.
That’s very true, and I do not like the term “serverless” for the rather obvious reason that it’s all about servers (someone else’s servers, that is). But these three principles are handy for figuring out if you’re building with in a serverlessy kind of way:
- You have no knowledge of the underlying system where your code runs.
- Scaling is an intrinsic attribute of the technology; so much so that it just happens automatically.
- You only pay for what you use.
Abstraction; scale; consumption.
Garrett’s observation is spot-on here:
This is a very important point:
It’s important not to try making the no-JS experience work like the full one. The interface has to be revisited. Some features might even have to be removed, or dramatically reduced in scope. That’s also okay. As long as the main features are there and things work nicely, it should be fine that the experience is not as polished.
When the game developer Blizzard Entertainment decommissioned some of their server blades to be auctioned off, they turned them into commemorative commodities, adding an etching onto the metal frame with the server’s name (e.g., “Proudmoore” or “Darkspear”), its dates of operation, and an inscription: “within the circuits and hard drive, a world of magic, adventure, and friendship thrived… this server was home to thousands of immersive experiences.” While stripped of their ability to store virtual memory or connect people to an online game world, these servers were valuable and meaningful as worlds and homes. They became repositories of social and spatial memory, souvenirs from WoW.
The carbon cost of collecting and storing data no one can use is already a moral issue.
So before you add another field, let alone make a new service, can you be sure it will make enough of a difference to legitimise its impact on the planet?
The way you build web pages—using
IntersectionObserver, for example—can have a direct effect on the climate emergency.
Webpages can be good citizens of battery life.
It’s important to measure the battery impact in Web Inspector and drive those costs down.
Harry takes a deep dive into the performance metric of “time to first byte”, or TTFB if you using initialisms that take as long to say as the thing they’re abbreviating.
This makes a great companion piece to Drew’s article on server timing headers.
Chris broke both his arms just to avoid speaking at the JAMstack conference in London. Seems a bit extreme to me.
Anyway, to make up for not being there, he made a website of his talk. It’s good stuff, tackling the split.
It’s cool to see the tech around our job evolve to the point that we can reach our arms around the whole thing. It’s worthy of some concern when we feel like complication of web technology feels like it’s raising the barrier to entry
IntersectionObserver to lazy load images—very handy for webmention avatars.
Tom makes an endpoint for generating QR codes so you don’t have to rely on the Google Charts API.
He also provides a good definition of “serverless”:
Now, serverless is a very silly buzzword dreamed up by someone from the consultant class who love coming up with terrible names, so I promise I won’t use it any further. Your code obviously run on a server. It just means it runs on a server someone else manages.
Amazon call it a ‘Lambda Function’. Google call it a ‘Cloud Function’. Microsoft Azure call it simply a ‘Function’. But none of those are very descriptive, because, well, anyone who writes any kind of programming language generally writes functions pretty much all the time in much the same way as anyone who writes English writes paragraphs, and we don’t call our blogging software “Cloud Paragraphs”. (Someone will now, I’m guessing.)
At Codebar the other night, I was doing an intro chat with some beginners. At one point I touched on DNS. This explanation is great for detailing what’s going on under the hood.
I would urge front-end developers to take a step back, breathe, and reassess. Let’s stop over engineering for the sake of it. Let’s think what we can do with the basic tools, progressive enhancement and a simpler approach to building websites. There are absolutely valid usecases for SPAs, React, et al. and I’ll continue to use these tools reguarly and when it’s necessary, I’m just not sure that’s 100% of the time.
This is my kind of URL nerdery. Remy ponders all the permutations of URLs ending with slashes, ending without slashes, ending with with a file extension…
This is a really clever technique from Scott that he unveiled at An Event Apart in Seattle. It uses a header sent by a service worker to distinguish between returning and new visitors—much neater than relying on a cookie. I’ve updated my service worker on The Session to use this technique now.
Harry breaks down
cache-control headers into steps that even I can understand. I’ll be using this a reference for sure.
Okay, I knew about the Python shortcut—I mentioned it in Going Offline—but I had no idea it was so easy to do the same thing for PHP. This is a bit of a revelation for me!
Once in the desired directory, run:
php -S localhost:2222
Now you can go to “localhost:2222” in your browser, and if you have an index.html or .php file in your root directory, you’re in business.
This is fascinating! A website that’s fast and nimble, not for performance reasons, but to reduce energy consumption. It’s using static files, system fonts and dithered images. And no third-party scripts.
Thanks to a low-tech web design, we managed to decrease the average page size of the blog by a factor of five compared to the old design – all while making the website visually more attractive (and mobile-friendly). Secondly, our new website runs 100% on solar power, not just in words, but in reality: it has its own energy storage and will go off-line during longer periods of cloudy weather.
Ping! That’s the sound of my brain going “service worker!”
I’ve sent them an email offering my help.
There are a lot of static site generators out there!
