Background: Limited data utilization in low-resource settings poses a barrier to the vaccine delivery ecosystem, undermining efforts to achieve equitable immunization coverage. In nomadic populations, individuals face an increased risk of missing crucial vaccination doses as children. One such population is the Maasai in Narok County, Kenya, where the absence of high-volume, quality data hampers accurate coverage estimates, impedes efficient resource allocation, and weakens the ability to deliver timely interventions. Additionally, data privacy concerns are heightened in groups […]

There is a scene in Plato that contains, in miniature, the catastrophe of Athenian public life. Two men meet at a courthouse. One is there to prosecute his own father for the death of a slave. The other is there to be indicted for indecency. [1] The prosecutor, Euthyphro, is certain he understands what decency requires. The accused, Socrates, is not certain of anything, and says so. They talk. Euthyphro’s confidence is striking. His own family thinks it […]

There is a particular failure mode that afflicts intelligent, well-informed people more than anyone else. It is not ignorance; they have the data. It is not a lack of analytical skill; they can follow the arguments. It is something more structural: an inability to feel how fast things are actually moving, even while holding the evidence in both hands. It has no clinical name, but it deserves one. Call it human amnesia. Not the clinical kind, but the […]

Modeling causal relationships in graph representation learning remains a fundamental challenge. Existing approaches often draw on theories and methods from causal inference to identify causal subgraphs or mitigate confounders. However, due to the inherent complexity of graph-structured data, these approaches frequently aggregate diverse graph elements into single causal variables, an operation that risks violating the core assumptions of causal inference. In this work, we prove that such aggregation compromises causal validity. Building on this conclusion, we propose a […]

Image Source: Vaultwarden Github Full text can also be viewed here. Password vaults are a convenient and secure way to manage multiple passwords. As data breaches become more and more common, security guidance changes lead to an inevitable mishmash of credentials that are impossible to remember when not used daily. The logic behind constantly-evolving password guidelines is beyond the scope of this guide, but recent word from NIST on password vaults recommends their use: Verifiers SHALL allow the […]

The data was fine. For now. That was the problem. Sharing something from my own work that stuck with me. Hope it resonates. I was not looking for it. I was in the middle of a data programme. SQL scripts, Power BI dashboards, process maps, the usual. Head down in the analysis, trying to make sense of what the systems actually held versus what people thought they held. Those two things are often quite different and the gap […]

No, no, I am not. But I managed to extend an enterprise-grade product with a new functionality. Does it work? Yes. Was it painful? Also yes. Is the code any good? Ehm. Let’s dive in, shall we? If you read my last piece on the “Synthetic Web,” you know I believe AI is a massive lever for productivity, but it requires a human to inject the variance, the taste, and the strategic direction. Recently, I decided to skip […]

A “market pulse” screen is basically the tab you keep open when you don’t want to stare at charts all day. It tells you what’s moving right now, what’s unusually volatile, and which names are starting to move together. Not in a research-paper way. In a product way. The kind of feed you could drop into a media platform or investing app and have it feel instantly useful. In this tutorial, we’ll build a minimal version of that […]
