Distribution Calculator vs Extended emulator of МК 61/54
Side-by-side comparison of two open source alternatives
Distribution Calculator
A calculator that can deal with distributions ergonomically, to allow users to easily arrive at fermi estimates that incorporate uncertainty. Tips: ■ The boxes represent the 90% confidence interval (5% to 95%) of your distributions ■ Swipe left or right to duplicate an input Try this example estimating the number of grams lost with a month of exercise lifting: 10 to 30 kg lifted per exercise × 0.25 to 0.75 meters lifted per exercise × 9.81 gravitational constant, to get to Jules (swipe left at the bottom to duplicate the input) × 10 reps per set × 3 to 4 sets per exercise ÷ 15% 35%, wild guess on chemical to physical efficiency conversion ÷ 4, jules to calories ÷ 6K to 8K, calories burnt to lose one gram of fat × 7 to 15 exercises in a gym session × 2 to 4 times a week × 4 weeks a month ÷ 10% to 30%, wild guess for share of loss that is due to the direct physical exercise (as opposed to higher burn rate, cost of building muscles, etc.) = ¿ to ? grams lost with the above exercise regime in a month
Extended emulator of МК 61/54
МК 61 was the best seller of all USSR programmable calculators of 1980-s (B3-34, MK-54, MK-56, MK-61, MK-52). Calculators are emulated on microcode level so they behave exactly like the original devices, including all non-documented features and inaccurate calculations. For ease of use application features saving and loading emulation states. This app's emulation engine Java code is based on C++ source of Felix Lazarev's emu145 project. Emulation was highly optimized for speed and should run in real time on any phone. It's an extended version of the original emulator МК 61/54 by Stanislav Borutsky (https://play.google.com/store/apps/details?id=com.cax.pmk). This version allows to export/import programs from external files and contains some UI improvements. Hint 0: you can found the list of all tips in the About dialog Hint 1: touch calculator's indicator to toggle slow/fast mode. Indicator's blinking looks better in slow mode. Hint 2: you can choose between MK-61 and MK-54 using menu option that becomes visible when calculator is switched off. Hint 3: with the menu "Import" you can import programs from external files, several such programs you can find in https://xvadim.github.io/xbasoft/pmk/pmk.html Hit 4: you can open menu by long tap on the "Вкл" label.
