I heard some points of criticism to how React deals with reactivity and it's focus on "purity". It's interesting because there are really two approaches evolving. There's a mutable + change tracking approach and there's an immutability + referential equality testing approach. It's difficult to mix and match them when you build new features on top. So that's why React has been pushing a bit harder on immutability lately to be able to build on top of it. Both have various tradeoffs but others are doing good research in other areas, so we've decided to focus on this direction and see where it leads us.

I did want to address a few points that I didn't see get enough consideration around the tradeoffs. So here's a small brain dump.

"Compiled output results in smaller apps" - E.g. Svelte apps start smaller but the compiler output is 3-4x larger per component than the equivalent VDOM approach. This is mostly due to the code that is usually shared in the VDOM "VM" needs to be inlined into each component. The tr

Background: we've had a conversation about using full words vs. single letters in function names. One argument against using full words was that it leads to long, Java-like names like getPropertyFromDictionaryOptionCurried.

The problem

Long names like getPropertyFromDictionaryOptionCurried are bad not because they are made of full words. They are bad because they are saying too much.

If single letters read more naturally than full words, then this would be an improvement:

When I switched over the C# compiler team, I had hoped that I would be able to give some insight into how the design team works, what decisions we make, etc. Language design is a very esoteric field, and there's not a lot written about it (though “Design and evolution of C++“ is a pretty good read). I had hoped that I would be able to do this with concrete examples, as that makes it much easier.

I've been watching for candidate topics to write about, but haven't yet come up with any good ones. One of the problems is that features have a tendency to morph in design (and in whether they'll make it into Whidbey) as time goes by, and it would be bad for me to say, “we're talking about doing“ and then have us decide it wasn't a good idea. Or, for us to decide that doesn't fit into our schedule, or it would break existing code, or any of the other reasons that might cause us t

let's start off with the simplest use case. we'll make an 'index.html' page, and assume we've setup our js bundler to output bundle.js

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
