InstaCalc VS Calca

Shout out to https://instacalc.com/ . It's like a simple spreadsheet or calculator but with awesome support for dimensional analysis -- you can attach any units you want to a quantity and it will track it throughout the calculations. For example, here's a quick scratchpatch I used for calculating memory bandwidth / CPU transfer rates: https://instacalc.com/56842. - Source: Hacker News / 8 months ago

Neat! I used to use https://instacalc.com/ for simple calculations, you can share your calculations, but it doesn't have the notepad feature like this one. - Source: Hacker News / over 1 year ago

In the wide niche on the complexity scale between your basic Windows* calculator and MATLAB sits instacalc.com. Source: over 2 years ago

For quick ad-hoc calculations I like https://instacalc.com/ because:. Source: almost 3 years ago

Surprised no one has mentioned https://instacalc.com yet. Not a native Mac app but genius. - Source: Hacker News / about 3 years ago

This looks fantastic. I will definitely give it a spin. I've been tracking what I call "computational scratchpad" apps for a while now but haven't found one that fits my environment/workflow yet. Maybe Heynote will. Here are some others that I've looked at: * https://soulver.app Granddad of them all, Mac-only, proprietary, expensive * https://numi.app Mac-only, proprietary, semi-expensive.

This is all in calca syntax so you can download that for free and copy-paste this whole post into it and change the numbers for your car or electric rates. Calca is like a spreadsheet met a text editor, it's great. I don't work for Calca it's just a great tool. Source: 5 months ago

Soulver. Useful to do calculations. I often find it useful while coding. Calca is even more powerful (you can almost program in it), but a lot less polished. Source: 12 months ago

The flip side to this is that Julia is a very capable general purpose engineering calculator and simulator. For example, calculating friction in hvac ductwork, voltage drop in long electrical circuits, solar gains for windows or solar panels facing various directions, cost/benefit analyses of thicker or thinner roof insulation and so on... These are all 1 to 10 lines of code so there isn't a big porting cost in... - Source: Hacker News / 12 months ago
