Privacy-leak detector for Java

I can provide a automated detection of privacy-leaks in Java classes using a custom static analysis tool.

Pronunciation-aware dictionary look-up

Algorithms for pronunciation-aware searches in dictionaries and other databases.

Software for finding wave-induced cracks

I have an application for finding wave-induced cracks in video inspections of sub-sea structures available for interested customers.

Case statements in Ada

A short screencast introducing the viewers to some of the benefits of how case statements work in Ada, and how the static coverage checking in the compiler helps preventing errors. The presentation includes some Ada 2012 features and also gives a basic introduction of subtypes (subsets). (Alternative version.)

Command-line driver generator

An Open Source tool for generating command-line interfaces to Ada packages.

Sound recording and playback for Ada

An Open Source sound library for Ada providing recording and playback support.

POSIX in Ada

An appendix to the book Understanding Unix/Linux Programming making it Ada-based instead of C-based.

POSIX file descriptors as Ada streams

An Open Source Ada package wrapping a POSIX file descriptor (as declared in the POSIX.IO package from the POSIX Ada API) as an Ada stream. This allows you to stream Ada objects to/from any kind of file opened with the POSIX Ada API using just the standard stream attributes of Ada.

Mathematical modelling

Mathematical models designed to solve problems for your business.

Software development

Software development on a consultancy basis. I can provide time estimates and hourly rates, or fixed-price quotes depending on your needs. I have experience in a large variety of programming languages, among others: Ada, C, C++, Python, Oracle PL/SQL, Pascal, SPARK and Fortran.

Review of coding standards

Coding standards can benefit from a critical review from an experienced software developer. I provide reviews and constructive comments for coding standards for Ada source text.

Source code review

I can provide critical source text reviews, either during development or as an independent review of a final product before delivery/acceptance.

Software innovations

New business use of existing software technology, and development of new programming techniques.

Data analysis and processing

Analysis of and data processing for biological experiments.

Generating integration tests from use-cases

Slides from my talk on using tools to generate integration tests from use-cases at Driving IT in Copenhagen.

Generazione di test di integrazione da casi d'uso

I gave a presentation on semi-automatic test-generation from use-cases at Linux Day 2015 in Cagliari. Slides and examples are available for download.

More SPARK 2014

Thanks to an interesting question on Stackoverflow, I got around to set up a repository for collecting SPARK 2014 examples.

Ada DevRoom at FOSDEM 2016

Earlier today the list of DevRooms at FOSDEM 2016 was announced. This includes an Ada DevRoom organised by Ada-Belgium. Please submit proposals for presentations to <adafosdem@ls.kuleuven.be>.

Ada User Journal 36.3 is out

I just picked up my copy of Ada User Journal 36.3 from my mailbox. I really look forward to read the paper by A. A. Lovelace (even if it appears to be a reprint ;-).

HTTP redirector

Are you tired of having all kinds of people tracking which links you click, and which pages you visit on the web? My HTTP redirector attempts to solve this problem by providing you with a local, non-logging replacement for some of the trackers out there. The tool is Open Source and written in Ada.

Gopher concurrency exercises

I was pointed to some interesting programming exercises by a fellow Ada programmer. I took a few hours out of the calendar to solve them in Ada. One interesting observation is that the hardest part of the exercises was to make nice terminations of the programs. The actual synchronisation and communication is easy to do in Ada.

LEGO brain - MR scanners

I have built a model of a human brain in LEGO for an exhibition at Medical Museion in Copenhagen.

Combining SPARK 2014 and Ada 2012

I have created a minimal example showing how SPARK 2014 proofs and Ada 2012 run-time checks of the same contracts can be done. In the example there is a simple increment procedure with a precondition, which either can be checked at compile-time (by a SPARK 2014 prover) or at run-time (by compiler-inserted checks).

Persistent Containers

I have done some work on persistent containers for Ada 2012 in connection with a paper I have submitted to the Ada Europe 2015 conference. While I expect to keep the interface to the containers unchanged, I plan to change the implementation drastically.
