The Demise of the Mildly Dynamic Website

It me:

Broadly, these are websites which are still web pages, not web applications; they’re pages of essentially static information, personal websites, blogs, and so on, but they are slightly dynamic. They might have a style selector at the top of each page, causing a cookie to be set, and the server to serve a different stylesheet on every subsequent page load.

This rings sadly true to me:

Suppose a company makes a webpage for looking up products by their model number. If this page were made in 2005, it would probably be a single PHP page. It doesn’t need a framework — it’s one SELECT query, that’s it. If this page were made in 2022, a conundrum will be faced: the company probably chose to use a statically generated website. The total number of products isn’t too large, so instead their developers stuff a gigantic JSON file of model numbers for every product made by the company on the website and add some client-side JavaScript to download and query it. This increases download sizes and makes things slower, but at least you didn’t have to spin up and maintain a new application server. This example is fictitious but I believe it to be representative.

Also, I never thought about “serverless” like this:

Recently we’ve seen the rise in popularity of AWS Lambda, a “functions as a service” provider. From my perspective this is literally a reinvention of CGI, except a) much more complicated for essentially the same functionality, b) with vendor lock-in, c) with a much more complex and bespoke deployment process which requires the use of special tools.

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.)
