statement on event-stream compromise

Hey everyone - this is not just a one off thing, there are likely to be many other modules in your dependency trees that are now a burden to their authors. I didn't create this code for altruistic motivations, I created it for fun. I was learning, and learning is fun. I gave it away because it was easy to do so, and because sharing helps learning too. I think most of the small modules on npm were created for reasons like this. However, that was a long time ago. I've since moved on from this module and moved on from that thing too and in the process of moving on from that as well. I've written way better modules than this, the internet just hasn't fully caught up.

@broros

otherwise why would he hand over a popular package to a stranger?

If it's not fun anymore, you get literally nothing from maintaining a popular package.

One time, I was working as a dishwasher in a restu

Deterministic save load in Factorio

One of the key parts of the save/load process in Factorio is that it must be deterministic. This means that for a given save file (when no external factors change) saving, exiting, and loading the save shouldn't change any observable behavior.

There are a few reasons and benefits for this strict requirement:

  • Without it: You couldn't join a running multiplayer game (and by proxy save, exit, and resume one)
  • Without it: the replay system wouldn't work if you ever saved, exited, and resumed playing.
  • With it: we can easily test that saving and loading produces no observable change letting us know we implemented save/load correctly.
  • With it: you won't see things change randomly as a result of "reloading" like you do in so many other games.

Quirks of C

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

Amazon's Build System

Prologue

I wrote this answer on stackexchange, here: https://stackoverflow.com/posts/12597919/

It was wrongly deleted for containing "proprietary information" years later. I think that's bullshit so I am posting it here. Come at me.

The Question

Amazon is a SOA system with 100s of services (or so says Amazon Chief Technology Officer Werner Vogels). How do they handle build and release?
