I have one as a watch bezel that I use in a pinch. Anything you need to scale, divide, or multiply in the real word doesn't need more than 2 significant digits of precision so it works. For example, I've used it to calculate how many grams of coffee will give me a 1:16 to the amount of water/coffee I want.
I have a Swiss Micros DM42, a modern clone of the HP42s on my desk and I have the plus42/free42 app on pretty much every device I own. Stack based calculators are great because the stack works as a little scratchpad when I'm trying to figure something out.
If I'm solving a problem of any complexity I'll move to a more appropriate tool like python or a spreadsheet, but for the simple math that needs to be done around the edges personally and professionally, I like a calculator. If I'm at my desk, I'll use the physical version.
Me too. Love my DM42. I also have an HP35s and two HP12Cs still on the batteries they were rocking over 10 years ago when I used them daily in my finance days.
To answer the op's question, any RPN calculator is wildly better than the default calculators on things like iOS once you take the time to learn to use it[1]. If you want a good calculator app, Thomas Okken's free42 is a great, free HP42S emulator which runs on iOS. I still prefer a physical calculator (eg the swissmicros has more screen space so you can see 4 lines of stack and dedicated function buttons) but it's much better than the default.
[1] Great support for complex numbers in polar or rectangular form, fewer keypresses for multi-step operations, no ambiguity (whatsoever) about operator order without any need for parentheses, vast number of memory slots (not just one), the ability to write a program to do anything you can do manually on the calculator so you can automate anything you do frequently, numerical integration and root finding etc etc there are many many benefits.
Bluesky is far from perfect, but I think you need a realistic comparison to other social media networks. Twitter is far more toxic if you are unable to curate your feed. Mastodon has a nice community, especially for tech, but lacks breadth.
There is a core group at Bluesky of people that left Twitter and they have an obvious slant, but I really don’t see this issue making the network worse than any other and only requires you to curate your feed like you have to do on every network.
I don’t really like this view of the world. I think they are correct about the lack of certainty and doing things while you can, but often big goals, like having a child, professional success, monetary success, etc. can cause us to miss life, too. Everything is a trade off. There’s always opportunity cost and you can always look back and see what you may have sacrificed to get where you are.
It’s needlessly depressing to wallow in this mindset. I personally value being a good person and my connections with people. Sure I could focus this energy on one human I bring into the world, but that’s not objectively better than anyone else I affect positively.
And I know having a child is a transformative experience. I’m lucky enough to have lots of little cousins and Have volunteered with programs for kids for years. Kids are amazing and bring magic to the world as you grow older. I just think that wrapping all of your identity and self worth up in a single goal is asking for disappointment. It’s not fair to you or the child.
Try to appreciate your real impact on the world. Did you improve someone’s day today? Did you restore someone’s faith in humanity? Is someone comforted right now by their trust in you? That’s the good stuff. Make that happen any way you can.
If you do want a child, go for it. Time IS ticking, but if you can’t or didn’t or are considering bring one into a bad situation or relationship to quell an existential fear, don’t worry. It’s fine. You can still find meaning and have an impact through your connections with others.
I really like having totp functionality. I use a yubikey for TOTP and boot into an air gapped machine with keypass to store the TOTP codes in case I lose or break the yubikey. I don’t store TOTP codes in my main password manager, but it’s not completely insane. You’re screwed if someone gets your decrypted password database, but you’re still protected from most other attack vectors.
