I just finished 75 Hard and one thing that surprised me was how hard it was to find a really minimal way to track progress. Most of what I found was either overly complicated or bundled into big habit apps. So I built something simple for myself and put it up at 75hardcalculator.com.

You enter your start date and it shows: • What day you’re on • How many days are left • Your exact finish date • A simple 75-day visual so you can see the days stacking up

No account needed. Just a clean way to see where you are and how close you are to Day 75. If you’re in the middle of it (or about to start) and want something minimal, it might help.

Interesting, as an American, I read the date in the video (02.04.2025) as February 4th, 2025 (I agree that the DD/MM/YYYY format makes more sense, but dates are commonly listed MM/DD/YYYY everywhere here). It makes me realize when doing a worldwide release, it's important to be as explicit on the date as possible.

The input data is predictable, so it can easily be filtered out by a rule.

I built a service that makes sure your forms are always working — no more lost leads due to something breaking. Currently bringing in over 1k/mo: https://formtester365.com

It fills out the form as a human would (daily or on whatever weekly schedule you want) and then confirms it was received. It currently supports Gravity Forms on Wordpress due to their API for confirming submissions, but a new version that supports all web forms is nearly ready.

One of the main use cases is for agencies that want to make sure clients sites are always working.

I'm interested in reading that essay — is this the one? https://www.gutenberg.org/files/3250/3250-h/3250-h.htm

Thank you — I had tried a search on hn.agnolia.com for "natural gas" in the last week, but I see now that was the wrong search term...I posted simply because I wanted to see the discourse on this study.

This guy is doing something similar with heat pumps and water storage - specifically utilizing radiator and boiler along with heat pumps: https://www.2040energy.com

Great suggestion! I just added this — and it worked as expected (mostly). If the Apple Music app is in MiniPlayer mode, it will not automatically switch to the full player, but thankfully, closing the MiniPlayer immediately drops you into the search results. Thanks!

This makes me sad (even as I wish them the best). Postmark may be one of my favorite services 1) to actually use and 2) as a company. Their product is actually fun to use and powerful. As a company, Wildbit is one I've always had high respect for. Their "People-First" approach says it all, and they seem like a company that truly acted on that.

I understand the reasons for the acquisition, and I hear the message that product continuity is the goal, but I can't think of an example of a product acquisition that hasn't resulted in a worse experience (at least with a product as good as this one). I'd love to hear examples if anyone has any.

I'm happy for Postmark overall though, and I want to express gratitude for creating a great product and company.

My side project, FormTester 365 https://www.formtester365.com has been doing a little over $700/mo now. Many customers are agencies who want to be alerted if a client's web forms stop working.

It tests website forms daily (currently as a Gravity Forms plugin add on) and confirms that they were successfully submitted. I'm working to add support for general web forms in the next few months. Feel free to send me an email if you're interested in being notified when that feature rolls out — jon (at) creativeculturemedia.com
