SDR software running on the ADALM Pluto.

This is a Linux industrial I/O (IIO) subsystem driver, targeting RF Transceivers. The industrial I/O subsystem provides a unified framework for drivers for many different types of converters and sensors using a number of different physical interfaces (i2c, spi, etc). See IIO for more information.
Provides details which are useful for programming the ADALM Pluto SDR.

A Hewlett Packard Infrared Signal Decoder
Martin Hepperle
June 2015
Several Hewlett Packard pocket calculators are able to send printer output via Infra-Red (IR) signals to a small portable printer. They use an HP-specific transmission protocol which is also called “Red Eye”. This protocol is different from the better known IrDA protocol. This document gives a brief overview of the format and describes hard- and software to build a decoder system for this protocol.
This system allows receiving the “Red Eye” signals with a computer via a serial or an USB interface.

This is just an example, the site contains a large number of documents written at MIT.

PDF Tools is, among other things, a replacement of DocView for PDF files. The key difference is, that pages are not pre-rendered by e.g. ghostscript and stored in the file-system, but rather created on-demand and stored in memory.

This rendering is performed by a special library named, for whatever reason, poppler, running inside a server program. This program is called epdfinfo and its job is it to successively read requests from Emacs and produce the proper results, i.e. the PNG image of a PDF page.

Actually, displaying PDF files is just one part of PDF Tools. Since poppler can provide us with all kinds of information about a document and is also able to modify it, there is a lot more we can do with it.
