Show HN: Prodscape.net – Map your mobile app
Hello HN,<p>Long-time lurker, first-time poster here. I've created a service that creates a "flow map" of your mobile app.<p>Check it out at: <a href="https://prodscape.net" rel="nofollow">https://prodscape.net</a>.<p>The goal is to reduce last-minute regressions, promote holistic discussion, and help develop more ownership within an organization. This is something that I would have liked to have had when I was working at a big company.<p>Some caveats:<p><pre><code> 1.) Only iOS is currently supported but Android-support will be coming soon.
2.) You need a developer-signed IPA file (see the guide on creating an IPA file here: https://prodscape.net/finding-ipa.html).
</code></pre>
I would appreciate your thoughts on:<p><pre><code> 1.) your barriers to trying it
2.) your impressions of the map
3.) whether you're interested in applying this within your team
4.) anything else.
</code></pre>
<i>Don't have access to an IPA file?</i> Email me at illahi@prodscape.net and I will send you one to try.<p>Thanks!

Show HN: All desktop software calculators are wrong, so I had to build my own
A new calculator software cannot really bring attention (<a href="https://chachatelier.fr/chalk/" rel="nofollow">https://chachatelier.fr/chalk/</a>)<p>However, I wrote a full article explaining why I had to build something "new" that does not behave like usual desktop calculator softwares :<p><<a href="https://chachatelier.fr/chalk/article/chalk.html" rel="nofollow">https://chachatelier.fr/chalk/article/chalk.html</a>><p>TL;DR
All "small" calculator softwares I know share the same design flaws. And the GUI is not the only stumbling block in their poor efficiency. Handling correctly numerical approximations - expected or not - is crucial to trust the results. It is usually not done in lightweight tools. It should. So I prove that if I could do it, OS manufacturers could as well.

Hi guys. I just write an SQL builder. I want to know what you think.
Show HN: Mailwitness – Digital Signatures over Email
Hi HN,
I'm Marek Dopiera and I wanted to share the digital signature solution which I made with my software house. Your feedback would be much appreciated.<p>We've just launched it - it's a service for signing documents over e-mail - <a href="https://mailwitness.com" rel="nofollow">https://mailwitness.com</a>. It still has some rough edges, but hopefully it is useful already.<p>To sign a PDF with somebody, you e-mail them the PDF and put sign@mailwitness.com in CC. If they agree, they need to forward it to sign@mailwitness.com. When they do, you all get your document signed. You can generate PDFs from e-mail, too for convenience.<p>We made this to raise the safety bar of agreements made via e-mail. Via anecdotal evidence, we know that if people do not use services like DocuSign or HelloSign, they consider an e-mail conversation as proof or they print, sign and scan documents. I think we're offering more safety and convenience, because we're preventing the documents from alteration, forging fakes and backdating (by using OpenTimestamp, which essentially constructs a Merkle tree and puts its root into a Bitcoin transaction).<p>I'm hoping that our service becomes useful also because it doesn't require any sign-up (just one confirmation e-mail for Ts&Cs), it's free (in the basic model) and doesn't require the extra cognitive load on learning a web app or a mobile app.<p>You may argue, that one can create a fake e-mail account and use that. That's a valid point, but the reality proves that verification via e-mail is enough for lots of people (vide the agreements over e-mail or DocuSign or HelloSign). In the future we may create paid options, which would include extra identity verification. Even without that extra option, things are not as bad, though: if you use your work e-mail, it's usually your employer who verified your identity.<p>Another question you might have is spoofing. If your e-mail has a valid DKIM signature (which is the case for most major e-mail providers), we'll accept your message. If it doesn't we'll send you a message to verify that you can also receive e-mail.<p>For data safety, we have designed the service such that we discard the documents as soon as we process an e-mail (usually a low number of seconds).<p>Finally, there is legal safety. We operate under the EU law, which qualifies us as a "Trust service provider" and puts requirements on our service. What we do, qualifies as an "Advanced Digital Signature" and according to the EU law, cannot be denied legal effect based on the grounds that it is digital.<p>Monetization path is unclear yet - I want to see if this catches on and if yes, how people are going to use it. Some options include extra services like using your own certificate rather than ours or identity verification.<p>I would really love to hear your feedback - especially for what reasons you would not use it.<p>Thank you

Show HN: I made a privacy-first minimalist Backblaze
Creator here. I was looking for something as simple as Backblaze Personal [1] but privacy focused and open source. This is my attempt to build that.<p>Uses PyQt6 [2] for the GUI and Pyinstaller [3] for creating the platform specific binaries. The backup engine under the hood is Restic [4]. The server code is written in Laravel [5]. All the code is on GitHub [6].<p>I actually really like Backblaze (even use B2 for this offering behind the scenes) so this isn't meant to throw shade their way. Just wanted a private open source alternative. Something like Bitwarden but for backups.<p>[1] <a href="https://backblaze.com" rel="nofollow">https://backblaze.com</a><p>[2] <a href="https://pypi.org/project/PyQt6" rel="nofollow">https://pypi.org/project/PyQt6</a><p>[3] <a href="https://pyinstaller.readthedocs.io/en/stable" rel="nofollow">https://pyinstaller.readthedocs.io/en/stable</a><p>[4] <a href="https://github.com/restic" rel="nofollow">https://github.com/restic</a><p>[5] <a href="https://laravel.com" rel="nofollow">https://laravel.com</a><p>[6] <a href="https://github.com/blobbackup/blobbackup" rel="nofollow">https://github.com/blobbackup/blobbackup</a>
