PDF Lecture vs DB40X Utilisation & Stats

We interpret the word “Lecture” as a living and dynamically changing event. It’s the conversation and interaction between moderator and audience. PDF Lecture is designed to handle this kind of dynamic presentation like no other app. Tools like PowerPoint and Keynote are great to create and perform a predefined and static presentation. Beside this, they barely allow deviations from a predefined path and do not offer a way to log such changes and share them with the audience. PDF Lecture has been developed to fit exactly these needs. How to use PDF Lecture? • Create your slides with your favourite app • Export your content as PDF • Open and combine multiple PDFs • Use the Editing Tools to arrange your slides • Plug an external display or projector and run your presentation • Make your best presentation using the Lecture Tools • Use a Laser Pointer to steer the focus of your audience • Zoom to details on your page with a simple pinch gesture • Use your Apple Pencil to draw, note and highlight during your presentation • Add scribble pages to explain something in detail • Interact with the participants with ease • Share the final outcome with your audience PDF Lecture is designed for an evolving and dynamically changing presentation. It starts where other apps end, so we hope you like it. We are constantly developing, testing and improving the app and a bunch of new features are in the pipeline right now. Stay tuned for updates and improvements.

DB40X is a high-precision scientific calculator compatible with DB48X and inspired by the legendary HP48 series from Hewlett-Packard. It is not an emulator, but a redesign from scratch, which is faster, and delivers never seen before capabilities like computations in arbitrary precision. Like the original HP48, DB40X supports an unlimited stack, RPN and algebraic operations, complex numbers, based numbers, vectors, matrices, text, symbolic computations, numerical solving and integration, graphing and plotting, statistics, engineering units, and well over 1000 built-in functions. DB40X adds several HP50G capabilities, including a library of equations and constants covering mathematics, physics or chemistry. Using modern technologies, DB40X goes well beyond the original HP48 in many ways: - It is significantly faster, uses less memory, and features a higher-resolution 240x400 pixels graphical display. - Integer and decimal values can have an arbitrarily large number of digits, so you can compute log(pi) with 200 digits in a few keystrokes. - The six function keys feature up to three function per key, giving quick access to up to 18 related functions at a time. - Complex numbers can mix and match polar and rectangular form. - Symbolic operations extend to complex numbers, vectors and matrices. - Based numbers can be in any base from 2 to 36, and support any number of bits, making it easy to emulate a 23-bit or 512-bit processor. - Text is represented using Unicode instead of the proprietary HP encoding, facilitating data exchange with the rest of the world. - Multiple graphs can be distinguished using bitmap patterns. - Engineering units include all the modern evolutions of the SI system, and can be configured by the user, e.g. to integrate currency units with the exchange rate du jour. Converting between USD/hour and EUR/day has never been so easy! - A built-in hyperlinked help system documents functions simply by holding the corresponding key, and combine a quick start guide, a user manual and a reference manual. DB40X will run many user RPL programs as is. However, since it is not an emulator, it will not run any HP binary object, and notably will not run HP48 games or anything involving system RPL. Version 0.7.14 is an early-access release. Please consult https://github.com/c3d/db48x/blob/stable/doc/5-Unimplemented.md for a list of HP48 commands that are not yet implemented. DB40X is part of a family of compatible RPL calculators that include DB48X and DB50X. DB40X lacks the ability to write programs or data to disk, and RPL programs are limited to 40K.
