A Brief Scientific Biography of Robin Milner
A Brief Scientific Biography of Robin Milner Gordon Plotkin, Colin Stirling & Mads Tofte Robin Milner was born in 1934 to John Theodore Milner and Muriel Emily Milner. His father was an infantry officer and at one time commanded the Worcestershire Regiment. During the second world war the family led a nomadic existence in Scotland and Wales while his father was posted to different parts of the British Isles. In 1942 Robin went to Selwyn House, a boarding Preparatory School which is normally based in Broadstairs, Kent but was evacuated to Wales until the end of the war in 1945. In 1947 Robin won a scholarship to Eton College, a public school whose fees were a long way beyond the family’s means; fortunately scholars only paid what they could afford. While there he learned how to stay awake all night solving mathematics problems. (Scholars who specialised in maths were expected to score 100% on the weekly set of problems, which were tough.) In 1952 he won a major scholarship to King’s College, Cambridge, sitting the exam in the Examinations Hall which is 100 yards from his present office. However, before going to Cambridge he did two years’ national military service in the Royal Engineers, gaining a commission as a second lieutenant (which relieved his father, who rightly suspected that Robin might not be cut out to be an army officer). By the time he went to Cambridge in 1954 Robin had forgotten a lot of mathematics; but nevertheless he gained a first-class degree after two years (by omitting Part I of the Tripos). -
The History of Standard ML
The History of Standard ML DAVID MACQUEEN, University of Chicago, USA ROBERT HARPER, Carnegie Mellon University, USA JOHN REPPY, University of Chicago, USA Shepherd: Kim Bruce, Pomona College The ML family of strict functional languages, which includes F#, OCaml, and Standard ML, evolved from the Meta Language of the LCF theorem proving system developed by Robin Milner and his research group at the University of Edinburgh in the 1970s. This paper focuses on the history of Standard ML, which plays a central rôle in this family of languages, as it was the first to include the complete set of features that we now associate with the name “ML” (i.e., polymorphic type inference, datatypes with pattern matching, modules, exceptions, and mutable state). Standard ML, and the ML family of languages, have had enormous influence on the world of programming language design and theory. ML is the foremost exemplar of a functional programming language with strict evaluation (call-by-value) and static typing. The use of parametric polymorphism in its type system, together with the automatic inference of such types, has influenced a wide variety of modern languages (where polymorphism is often referred to as generics). It has popularized the idea of datatypes with associated case analysis by pattern matching. The module system of Standard ML extends the notion of type-level parameterization to large-scale programming with the notion of parametric modules, or functors. Standard ML also set a precedent by being a language whose design included a formal definition with an associated metatheory of mathematical proofs (such as soundness of the type system). -

MACALESTER COLLEGE HONORS PAPER IN COMPUTER SCIENCE Porting the Embedded Xinu Operating System to the Raspberry Pi Author: Advisor: Eric Biggers Shilad Sen May 5, 2014 Abstract This thesis presents a port of a lightweight instructional operating system called Em- bedded Xinu to the Raspberry Pi. The Raspberry Pi, an inexpensive credit-card-sized computer, has attracted a large community of hobbyists, researchers, and educators since its release in 2012. However, the system-level software running on the Raspberry Pi has been restricted to two ends of a spectrum: complex modern operating systems such as Linux at one end, and very simple hobbyist operating systems or simple “bare-metal” programs at the other end. -

THE PENNSYLVANIA STATE UNIVERSITY SCHREYER HONORS COLLEGE DEPARTMENT OF SECURITY AND RISK ANALYSIS BENEFITS OF CYBER SECURITY LABS ON RASPBERRY PI’S CARSON BROWN SPRING 2019 A thesis submitted in partial fulfillment of the requirements for baccalaureate degrees in Information Science and Technology and Security and Risk Analysis with honors in Security and Risk Analysis Reviewed and approved* by the following: Michael Hills Associate Teaching Professor of Information Sciences and Technology Thesis Supervisor Edward J. Glantz Teaching Professor of Information Sciences and Technology Honors Adviser * Signatures are on file in the Schreyer Honors College. i ABSTRACT With the growing number of cyber-attacks occurring in the world today, the need for robust cyber security education has never been greater. With many universities putting together their own respective cyber security curriculums, it is imperative to establish the most efficient ways to teach cyber security. This study intends to guide the decision makers toward using hardware, in our case Raspberry Pis, to perform labs instead of on virtual machines, which are the current standard. The beginning chapters will dive deeper into the studies purpose and explain to the reader to the current cyber security landscape. The next chapter describes how the labs and surveys were devised and explain the decision to use a Raspberry Pi as the Hardware for the study. The following chapters examine the results of the study and how they may impact future studies and curriculum. The final chapter discusses how this study can be continued and what further steps should be taken by those who believe in Raspberry Pis in the classroom. -
The Next Big Thing in Open Automation Is Here. Are You Ready?
The Next Big Thing in Open Automation Is Here. Are You Ready? Page | 1 © Western Reserve Controls, Inc. * 1485 Exeter Dr. Akron, Ohio 44306 * 330-733-6662 * [email protected] THE NEW AUTOMATION INDUSRTY DISRUPTOR Open Controllers… Open Networks… Open I/O devices… the world of Open Architecture automation is here with the Raspberry Pi and other Single Board Computers (SBC) becoming the IBM PCs of our time. From educational projects to industry disrupting Industrial Automation applications, Open Architecture Control & I/O Systems are changing the way many OEMs and Systems Integrators are thinking when it comes to implementing their next automation project. At WRC we believe the next 3-5 years will tell if this new generation of low cost SBCs and connected I/O will change the Automation Industry competitive landscape or fade away like so many other over-hyped automation technologies that have come and gone before. No matter what happens, when you hear people call When you hear people call SBCs SBCs like the Raspberry Pi a “prototyping platform”, like the Raspberry Pi a “prototyping a “hobbyist toy” or an “educational tool,” just platform”, a “hobbyist toy” or an remember what they said about the IBM PC. We’re “educational tool,” just remember going to start seeing these low-cost SBCs what they said about the IBM PC. everywhere and there’s no turning back! So the question is: Will your automation business be ready to take advantage of this new technology or become a victim of it like the once large corporations that fell to the lowly IBM PC? For example, if you’re a controls supplier, machine builder, Systems Integrator or End User there’s no doubt small, low-cost, SBCs like the Raspberry Pi will have an impact on your business in the next 3-5 years. -

Full PE a ∨ false → a a ∨ true → true of combinational logic is noted to be equivalent to Boolean minimisation.

Technical reports published by the University of Cambridge Computer Laboratory are freely available via the Internet: http://www.cl.cam.ac.uk/techreports/ ISSN 1476-2986 Abstract Most modern compilers are based on variants of the Control Flow Graph. Developments on this representation—specifically, SSA form and the Program Dependence Graph (PDG)—have focused on adding and refining data dependence information, and these suggest the next step is to use a purely data-dependence-based representation such as the VDG (Ernst et al.) or VSDG (Johnson et al.). This thesis studies such representations, identifying key differences in the information car- ried by the VSDG and several restricted forms of PDG, which relate to functional programming and continuations. We unify these representations in a new framework for specifying the shar- ing of resources across a computation. We study the problems posed by using the VSDG, and argue that existing techniques have not solved the sequentialization problem of mapping VSDGs back to CFGs. -
