[eurolisp] Student internship
by Thomas F. Burdick 22 Jul '06

22 Jul '06

If you know anybody who would be interested in this, please pass it along. thanks! The Cadence Design Systems VCAD group in Munich, Germany, is looking for a University student intern for a period of two to six months. You would be working on one of the following projects, depending on our needs and your strengths: * Project planning and scheduling software. This will be used to track our utilization of our developers, and to aid in planning for on-going and future projects. * Package configuration management software. We deliver to our customers custom configurations built out of a large number of pieces of software and other intellectual property. We are rewriting the system we use to specify, track, and build these deliveries. * Common Lisp bindings to a large C++ library. We are working on a system to automatically generate the low-level bindings, as well as designing a higher-level interface meant for direct use by application programmers. The implementation language for all of the above will most likely be Common Lisp, although lesser languages such as Java, Perl, and Tcl may play a role as well. We are looking for someone who either has experience programming in a Lisp language, or is interested in learning Lisp in a production environment, and is comfortable in several mutually unrelated programming languages (eg, C, Smalltalk, and PostScript; or Java, Prolog, and SPARC assembly language). Our environment is Unix-based (Solaris and Linux), so you should have a basic familiarity with Unix. Other things that would be nice, but are not required: some theoretical familiarity with relational databases (eg, you took a database class or read the textbook from one); Windows programming experience; Oracle experience; experience with C++, SQL, and Prolog. Virtual CAD (VCAD) is a group within Cadence providing EDA (Electronic Design Automation) related services. The internship is with the software development group within VCAD. Cadence's software products are scripted with the SKILL language, a Lisp language with two dialects: one Franz Lisp-like dialect, and one Scheme-like dialect. The VCAD software group also uses Common Lisp where appropriate. If you are interested, please contact Thomas F. Burdick (tfb(a)cadence.com), and Jim Newton (jimka(a)cadence.com) For more information about VCAD, see: http://www.cadence-europe.com/solutions/vpage.cfm?pID=1 http://www.cadence-europe.com/eEuronews/mar_05/features.html

[eurolisp] Fwd: Lisp (and Prolog, and a bit of KR) job, University of Newcastle upon Tyne, UK

Some of you may be interested in the following Lisp job announcement (forwarded from comp.lang.lisp). Arthur ---- Doorgestuurd Usenet-bericht ---- Van: Hamish Harvey <hamish(a)hamishharvey.com> Newsgroepen: comp.lang.lisp Onderwerp: Lisp (and Prolog, and a bit of KR) job, University of Newcastle upon Tyne, UK Datum: Fri, 08 Jul 2005 12:44:37 +0100 URL: news://<dalov5$kmp$1(a)ucsnew1.ncl.ac.uk> > I imagine that, regardless of the resurgent status of Lisp, jobs are still > thin enough on the ground for job notices to be welcomed here! > > The School: http://www.ceg.ncl.ac.uk/ > The University: http://www.ncl.ac.uk/ > The job: http://www.ncl.ac.uk/vacancies/vacancy.phtml?ref=D528R > > The Earth Systems Engineering group in the School of Civil Engineering and > Geosciences at the University of Newcastle upon Tyne, UK, are developing > software to support flood risk management. The core of this software is a > computation engine capable of taking definitions of rather complex, > multi-dimensional calculations and enacting them. The computation engine > will implement a domain specific language (DSL) designed to support the > expression of these computations in a declarative way. This language and > computation engine are being designed to provide the core of a wide range > of decision support systems from tools to support interactive analysis of > ill-specified problems to flood forecasting systems which depend on the > continuous, unattended assimilation of incoming data. > > The calculations involved in flood risk management involve embedding > numerical simulation of (parts of) the flooding system within layers of > higher level calculations to derive measures of flood risk (e.g. in > expected annual damage), or change in flood risk resulting from particular > interventions, or the sensitivity of particular outputs to uncertainty, > or .... The goal, in general, is to maximise the value of investment in > measures to address flood risk. Aspirations in the flood risk management > community far exceed what is feasible using current technology. To the > extent that such calculations are currently possible, they are achieved > using combinations of software packages and a great deal of munging of data > files. This approach is tedious and error-prone. It almost completely > obscures the structure and meaning of the underlying calcualtions, imposing > huge cognitive load on those undertaking them. It will not scale much > beyond the complexity of problem currently being tackled. > > The DSL under development by contrast allows these calculations, in their > full multi-dimensional glory, to be expressed succinctly in a form which is > amenable to human understanding but which can be compiled into an > executable form. Humans are more involved in defining calculations than > doing them. The language is declarative, based around a formalisation of > the concept of a "reference frame", which allows the structure of a > calculation (and of data sets) to be expressed explicitly (in imperative > implementations this structure is implicit in the control structure of the > code). > > The design of the semantics of the language is well progressed, but subject > to refinement as implementation proceeds. A limited prototype computation > engine exists which implements basic aspects of this language. The position > available is for a software developer to join me in working on this > prototype, which is written in Common Lisp (making extensive use of Lisp's > code-which-writes-code-which-writes-code capabilities). The work will > involve significant creative input at the abstract, conceptual level as > well as in translating from this abstract level into working code. It will > also involve applying the developing prototype to realistic flood risk > analysis case studies. > > Initial prototyping is using an ad hoc, s-expression-based concrete syntax > for the language. A further thread of development is to express the > language in a full knowledge representation language (which may dictate > changes to the abstract syntax). Part of the purpose of developing the > language is to support the expression of complex calculations succinctly in > a knowledge representation language. This language will then provide a > point of integration of a wide range of tools which operate in terms of the > structure of the calculation definitions, of which the computation engine > is but one. > > A draft report on the software is available. This has been written for an > audience of flood risk management professionals, not computer scientists or > software developers. It still needs a great deal of polishing, but > nonetheless sets out the breadth of the vision behind this project.

The intention is to obtain additional funds to continue this work for > some time, though this is subject to the vagaries of academic funding.
