FOSDEM is a non-commercial, volunteer-organized, two-day conference celebrating free and open-source software development. The conference has a geographic focus on European open source ecosystems and projects. FOSDEM is primarily aimed at developers, across the entire range of software and aims to enable them to meet and discuss the status of projects. We look into ten years of FOSDEM conference data to start getting to grips with the open source phenomenon and also explore techniques for data review and exploratory data analysis using (of course) open source python tools.
Interest in Sustainable Finance is growing What is “Sustainable Finance”? A working definition is: A financial system that takes into account environmental, social and governance considerations to ensure long term sustainability of the human economy. You can imagine that with a scope and ambition that sweeping, the devil hidden in the details will be of gargantuan size. The definitions of so-called ESG factors, the incorporation of sustainability into business strategies, the governance, policies and risk management applicable to ESG Risks, the ESG and climate-related disclosures and the development of “green” financial products are all topics that combine urgency, complexity and potentially dramatic impact.
Bending the Curve - Sustainability as a One Dimensional Exercise The opening of the Global Scenario Group report “Bending the Curve: Toward Global Sustainability” by Paul Raskin, Gilberto Gallopin, Pablo Gutman, Al Hammond and Rob Swart, published in 1998 goes as follows: Over the last few centuries, a mere heartbeat of historic time, humanity has moved to the brink of a new evolutionary milestone - the planetary phase of civilization. The world economy is expanding and becoming more integrated, profoundly reshaping the cultural and political landscape everywhere.
According to wikipedia Conflation is the merging of two or more sets of information, texts, ideas, opinions, etc., into one, often in error. This may lead to misunderstandings, as the fusion of distinct subjects might obscure analysis of relationships which are emphasized by contrasts. Why does conflation happen in the first place? There are several possible factors which in some contexts may be co-existing and overlapping: gratuitous (over)simplification driven by laziness or habit literacy gaps in either the originator or the receiver of information an objective to frame, mislead or otherwise be economical with the truth In this blog post we discuss a number of interrelated financial terms whose precise meaning is frequently intentionally or unintentionally obscured.
9 things they do not tell you about risk management Risks don’t fall from the sky, they are generated by other people Informal Risk Management was practiced by individuals since time immemorial. This is the domain of intuitive decision-making, assessing a situation on the spot and taking immediate action to avoid obvious risks. Over aeons empirical risk management has collected a treasure of heuristics, rules of thumb and colorful Risk Management One-Liners such as: There is never only one cockroach.
Graphs seem to be everywhere in modern data science: Graphs (and the related concept of Networks) have emerged from a relative mathematical and physics niche to an ubiquitous model for describing and interpreting various phenomena. While the scholarly account of how this came about would probably need a dedicated book, there is no doubt that one of the key factors that increased the visibility of the graph concept is the near universal adoption of digital social networks.
Data Types are a fundamental building block of data science Data science is about data, but data are not simple and tame beasts. They have character and attitude, which can cause a lot of friction between them and the data scientist. There is a lot of sweat and tears involved when confronting data, but data scientists can do worse than know how to handle in particular Data Type quirks. Namaly a good fraction of data science involves not modelling data, not transforming data, not even cleaning data but simply goading data around the right containers, providing them with the right stage that fits their character.
What is the future of stress testing? To speculate on the future of Stress Testing we need first a basic definition what stress testing is. Broadly speaking, the goal of Stress Testing is to assess how a system would behave under adverse conditions that - while not the most likely outcome with the knowledge of today - are within the realm of the plausible. There are, broadly speaking, two types of stress testing: The Real stress testing version and Hypothetical stress testing version.
Introduction: What is FOSDEM? FOSDEM is a non-commercial, volunteer-organized event centered on free and open-source software development (with a geographic focus on the European open source ecosystems / projects). FOSDEM is aimed at developers and anyone interested in the free and open-source software movement. It aims to enable developers to meet and to promote the awareness and use of free and open-source software. FOSDEM is held annually since 2001, usually during the first weekend of February, at the Université Libre de Bruxelles Solbosch campus in the southeast of Brussels, Belgium.
Risk, Randomness, Uncertainty and other Ambiguous Terms Uncertainty versus Risk is a popular discussion topic among risk managers, especially after major risk management disasters. The debate can get really hairy and drift into deep philosophical areas about the nature of knowledge etc. Yet the significance of having an as clear as possible language toolkit around these terms should not be underestimated. Practical risk management typically shuns too deep excursions into the meaning of things, yet that is not quite compatible with the use of sophisticated methods and tools (such as a Risk Model ) that assumes an understanding of the scope and limitations of “knowledge”.
Is the size of global debt truly “astronomical”? The notion of astronomical numbers and figures is quite frequently seeping in everyday language when large quantities of something are encountered in “normal” life. The strict definition of astronomical is obviously something of, or relating to, astronomy and astronomical observations but in common usage it also denotes something enormously or inconceivably large. This is, of course, because astronomical figures are inconceivably large!
The role of simulation in risk management and decision support A Simulation is a simplified imitation of a process or system that represents with some fidelity its operation over time. In the context of risk management and decision support simulation can be a very powerful tool as it allows us to assess potential outcomes in a systematic way and explore what-if questions in ways that might otherwise be not feasible. Simulation is used when the underlying model is too complex to yield explicit analytic models (An analytic model is one can be “solved” exactly or with standard numerical methods, for example resulting in a formula).
What is Risk Compensation? Risk Compensation is a behavioral model of human attitudes towards risk which suggests that people might adjust their behavior in response to the perceived level of risk. It follows that, depending on the strength of the effect, that it might counteract and even annul the impact of risk mitigation, if the updated attitude and behavior modifies the actual underlying risk Examples of potential risk compensation effects abound A prominent example of potential risk compensation in recent times that established the concept in more formal terms in public policy debates concerned the beneficial role of safety belts in automobiles.
Agent-Based Models: The origins and early years According to Wikipedia an agent-based model (ABM) is ABM: class of computational models for simulating the actions and interactions of autonomous agents (both individual or collective entities such as organizations or groups) with a view to assessing their effects on the system as a whole. A cellular automaton is a particular class of ABM. It is a discrete dynamical model used and studied in a variety of fields: computer science, mathematics, physics, complexity science, theoretical biology among others.
A survey of existing definitions of risk: When looking up the meaning of Risk we are confronted with a surprising situation. There is no satisfying and authoritative general purpose one-line definition that we can adopt without second thoughts. Let us start with the standard dictionary definitions: The online Merriam Webster Dictionary defines risk as the possibility of loss or injury The online Cambridge Dictionary opines that risk means the possibility of something bad happening The Oxford English (Concise, Hardcover!

What is a Risk Taxonomy? There are formal definitions of risk taxonomies (and we will go over those below), but it might be useful to first look at a very intuitive example of a risk taxonomy: the classification of fire hazards (also known as fire classes) Everybody knows (or should know!) that the different types of fire (the underlying Risk in this context) cannot be treated the same way because they respond in different ways to the substances used to suppress the fire.
The new IFRS 9 financial reporting standard: IFRS 9 (and the closely related CECL) is a brand new financial reporting standard developed and approved by the International Accounting Standards Board (IASB). Strictly speaking IFRS 9 concerns only the accounting and reporting of financial instruments (e.g. bank loans and similar credit products). Yet the introduction of the IFRS 9 standard has significant repercussions beyond financial reporting, and touches e.g., bank risk management as well.
Data Scientists Have No Future: The working definition of a Data Scientist seems to be in the current overheated environment: doing whatever it takes to get the job done in a digital #tech domain that we have long neglected but which is now coming back to haunt us! That is nice urgency while it lasts, but it is not a serious job description for the future. You will always find entrepreneurial institutions to offer degrees and certifications on the latest trending hashtag.
