Can we despite + this compete with GNU MP and still have a simple + solution? This is a discussion about libzahl's design + and future. + +(10:45-11:15) XML damage control, Silvan Jegen + + XML is a horrendously abused file format that suffers severely from + over-engineering. There arguably is one legitimate use case for (a subset + of) XML however: text markup. In this presentation I will show why that + is and how to best deal with XML when encountered in such circumstances. + + To ease the pain for people like me who have to work with XML every day, + I will first give an overview of different parsing strategies employed in + XML libraries and introduce the most bearable APIs of the ones available. + + The second part of the presentation is dedicated to the benchmarking of the + most sensible XML libraries and to the discussion of possible alternative + parsing approaches as well as their implementation. + +(11:20-11:50) Stali Pie B+, Manu Raster + + Report on readying Stali for the Raspberry Pie B+ (32 bit). It is + also a story about monsters and maiden when we take into comparison + other piles of code (kernels, distros etc.) and their build + systems. Portability conceptions encountered en route are + reviewed and ranked from 1 to 3 (depraved, naive and not too bad). + +(12:00-13:00) Lunch break + +(13:00-13:50) SCC and QBE for practical compilation, Roberto E. Vargas Caballero + + For now decades, we have witnessed a dramatic increase in the complexity + of compilers. Mainstream compilers have become huge C++ programs that try + to incorporate all the state-of-the-art research. SCC and QBE propose a + new approach to compilation where simplicity and predictability prime over + reckless efficiency. These new design constraints have security benefits + (as advocated by the "boring crypto" movement) and allow bootstrapping + new systems more easily. + +(14:00-14:25) ii-like chatting improvements, Jan Klemkow + + Since slcon2 I have made several improvements in my ii-like + chatting infrastructure. In this talk I will show the hole + picture of my different activities in this area. I will show + new features in my UCSPI tool chain, a new modular front end + 'lchat' and me idea of an runit integration. + +(14:30-15:15) text engine, Francesc Hervada-Sala + + Francesc will introduce his text engine experiment. + +(15:20-15:55) Suckless Image Processing, Enric Meinhardt-Llopis + + An image is an array of numbers. Since arrays of numbers are + natively represented in C, this language is well-suited for image + processing algorithms. Moreover, many complex image processing + algorithms are pipelines of simple, independent steps. Thus, + the UNIX programming environment is an ideal platform for image + processing, where several simple programs written in C share + information through UNIX pipes. In this talk, we will see many + examples of simple image processing utilities (blur, local maxima + detection, interpolation, warping, pointwise algebraic expressions, + morphological filters, block matching, optical flow, image fusion) + and how they are naturally combined to perform advanced imaging + techniques; in the selected example, we show a reflection removal + method based on the combination of several images. An important + issue, with far-reaching philosophical consequences, is the data + format written through the pipes. We explain why the farbfeld image + format---proposed by the suckless community---is inappropriate in + general, because of the need to represent negative and floating-point + pixel values. + +(15:55-16:10) Coffee break + +(16:10-16:30) shared farbfeld, Jan Klemkow + + Farbfeld is a very good base for general purpose image + processing. The Tools which were made so far demonstrate how + easy image processing could be divided into cooperative + programs. This talk will show an interface to speedup + the usage of different farbfeld tools with shared memory. + I will show and discuss an idea for an simple architecture of a + suckless like photoshop based on my interface, is first + implementation and some benchmarks i made. + +(16:35-17:15) Lightning talk session (please announce until Sep 23 for easier planning). + +(17:15-17:30) stali learnings Anselm R Garbe + + Anselm will present his learnings with stali since last slcon2. In + particular he will discuss his new goals with stali and reasoning + behind why making stali self-bootstrappable is a bad idea. + +(17:30-17:55) stapi - stali for Pi as bee hive observation platform, Anselm R Garbe + + Anselm will demonstrate his stali porting efforts for the Raspberr Pi + in order to have a nice platform for observing his beehives.
