What up nerds, I'm Jerod and this is Changelog News for the week of Monday, February 13th, 2023. |
My favorite nerdy artifact from last night's Super Bowl was [Twitter user pattymo taking a picture of Rihanna floating above the field on her platform and overlaying Bowser, Kirby and Captain Falcon from Smash Bros on it. The tweet's text was an all caps: RIHANNA LOOK OUT](https://twitter.com/pattymo/status/16249480222... |
But I digress. Let's get into the news. |

How much can you really get out of a 4$ VPS? That is what Alice GG was wondering when she decided to perform her own load test to figure out if the promise of running your production app on such a low budget is realistic. |
So, she coded up a simple CRUD app in Go, hooked it up to MongoDB because... |

and deployed it all to a $4 VPS of an unnamed provider using Docker with docker-compse. |
She then used K6, an open source load testing suite that generates virtual users who continuously run test scenarios using JavaScript, to see what the machines was capable of. |

I'll leave out the gory details, you can read them if you'd like, but her final conclusion is this: "as long as you don’t plan on building the next Twitter, a very cheap VPS might be fine for the start of a project." |
She goes on to say YMMV, DYOR, and shares the source code to her app, K6 scenarios, and analysis script. |

Brett Cannon asked an interesting question on his blog the other day. Should we use TOML for `.env` files? He's specifically asking in the context of the Python extension for VS Code, which Brett helps to maintain, but it might be a good thing to consider across the broader developer ecosystem. |
If you aren't familiar with `.env` files, they are a very common way of defining configuration settings outside your app code so you can keep them out of source control and easily load them as environment variables at run-time. But, they have their problems. The two that Brett lists are that `.env` files don't have a s... |
His proposed solution to this: use TOML, which is a widely supported config file format for humans, as the format for `.env` files. |
Brett wants to know what you think! Is this a good idea or a bad idea? Do people like the idea of a e.g. .env.toml (or env.toml or .env with an assumption of TOML syntax)? Is this worth trying to get various tools to support? |

Nic Mulvaney and his team at Normally.com developed and wroute about a super cool hack. The challenge: count unique visitors to a website without using cookies, UIDS, or fingerprinting. |

Privacy is why they're doing this and how they're doing it is the following. "When the browser pings our server from a website for the first time, we send back a response with a header set to Cache-Control: no-cache, telling the browser to store the request in its cache but revalidate it with the origin server before e... |
If that sounds confusing to you, check out the blog post which has a nice image of the process. I'll also embed it in the chapter data so take a look there if your podcast app is cool like that. |

Chris Coyier says after a few months, he's still using the Arc browser. |

Here's what Chris has to say about it: "It’s Chrome under the hood, so any extension will work, it has the exact same platform features, it has the same DevTools, etc. But the UI and UX are pretty different! That could put it at risk for a switch-back, but so far I find nearly every choice Arc makes an improvement." |
Things Arc does that Chris likes include syncing tabs between computers, providing easily editable user stylesheets, building in a split view, which he says is great for writing, moving tabs to the side, which he's convinced is the future, and more. |
High praise from a web developer who's opinion is highly refined after decades of doing this stuff. Unfortunately for many of us, Arc is Mac only for now and you can't just go and download it. Instead, you pop your email into a Typeform to join the waitlist. |
