I’d say it’s kind of nice. Something very pleasing about having the two lines, but it is not more functional as a result. The constants/conversions are very nice and well-implemented. Think some people will find them useful for day to day stuff or at school.
Oh wow, the whole thread is just people suggesting alternatives!! OP - enjoy your neovim and don’t listen to the rest. It’s a terrific editor and will be around for many decades more.
That thing holds it’s place in computing history. Kinda the first pocket computer?
He really likes it. The titanium back has given a great looking engraving of his initials. Now just hoping he didn’t lose it!
Respect for the 4 level stack!
Very nice! Was this a rebranding of another make or made by radioshack themselves?
Ah yes that’s a pretty nice graphing calculator, also looks pretty good in pink!
I think I like the buttons and the highly-specialised functionality. At least that’s what I think when people say ‘what’s the point, you have a far more powerful calculator in your pocket already’. Yes, one without buttons.
It is! Not mine sadly, but amazing to see such a thing. I didn’t have much time so apologies for not stopping down enough - I didn’t realise at the time!
Yes, looks like coated aluminium - not unlike a can but a little thicker and with no sharp edges. I’ve not seen these before but I think they are disposable/recyclable - i.e. a replacement for a plastic cup and far more pleasant to drink from. I took mine home as a souvenir, but I have had to unsquish it today taking it out of hold luggage.
Yes, in fact before I got my DM42 I had one holiday where we had no internet access in the evenings and as the children were small and slept early, I didn’t have much to do but I was able to learn a lot about using and programming free42.
You do have to remind yourself at the beginning that you’re using RPN, but after a while it feels a bit like working sums out on paper.
Just to clarify - means two taps of the esc key in succession will clear highlighting (ps I’m curious how other people do it!).
nmap <esc><esc> :noh<return>
Yes, I also have caps mapped to esc, but done in keyboard firmware so that holding it functions as ctrl.
In neovim I have two escapes mapped to :noh
Yeah, I think they need to tune their nibs before they let them out. No such thing as too much flow - just too little paper.
I was too stupid to realise how hard they were to do right.
That’s lovely - these calculators are very ‘dad’ style to me also (though my dad had a 70s style Casio). There’s something about the voyager HP calculators with their landscape format - they are really satisfying to use, I can see why he kept it on him!
It’s a Stilform fountain pen. They are a recent make using machined parts and bock nibs with a nifty magnetic cap. I’m having slight issues with the bock nibs though - they are going to need a bit more work to keep the flow how I like it.
I always thought of financial calculators as a sort of gelded single-function function machine and I didn’t really get them. However, that would ignore the vast number of models available from HP, and that their second ever pocket calculator was a financial one. It turns out that solving the time value of money equation is non-trivial, and the work done on that probably paved the way for calculators with a solver.
The other thing I didn’t appreciate until I had to use it, is that the interface of the 12c - with the 5 buttons in the top left for n, i, pv, pmt and fv is peak user interface. Press once to input data, but a second consecutive press of these buttons will trigger the solve and drop the result into x. It’s perfect, and means you can solve and use all the calculator functions and stack continuously. Most modern methods use a table, which is hard to extract and input information from the calculator.
Ah, it’s now obligatory!
