No-node app builders are certainly no panacea, and I say that as a co-founder of an app builder (Calcapp). However, if your requirements fall into a domain that is common enough that no-code tools exist, people who don't consider thems

Thanks, I see this behavior too. Interestingly enough, there's nothing on the page itself that can cause this behavior, this is all due to the sample calculator app embedded in an iframe element. We use the HTML5 History API to ensure

If the HN hive mind can agree on better terminology, I'd be happy to update the calculator.

Glad you like it. If you or anyone else need a calculator to share on Hacker News, let me know and I'll make sure it can be launched an unlimited number of times for free. (Otherwise, you'll quickly bump into the limits of our fre

There is actually a <noscript> element, but it isn't showing because the CSS opacity of the <body> element is set to 0. That's a fairly recent change which inadvertently broke the <noscript> text. We'll need

You can specify what separator to use as the first line in the CSV file: sep=, My experience is that Excel 2007 and later will correctly parse the file and use the specified separator. However, other software, such as Google Sheets, will si

The product is horizontal in the sense that it is applicable in a variety of domains, much like spreadsheets. Most of the ~10,000 apps that have been created with our beta relate to pricing and other economic calculations, often created by

The book looks great, I've ordered a copy. Thanks! As I mention elsewhere in the thread, we have been advised to not let the "newsworthiness" of our launch go to waste, meaning that we should take the opportunity to get some

by davidpolberger 9y ago
That's great advice. We have a B2B product and, as you say, we need to get our message out to these specific users. Frankly, I don't think that our "launch" will matter much down the road, but we have been advised to not
