Steps towards an ecology of the Internet / Jun 2025

Every ten years, the city of Aarhus throws a giant conference to discuss new agendas for critical action and theory in computing. Back in 2016, Hamed Haddadi, Jon Crowcroft and I posited the idea of personal data stores, a topic that is just now becoming hot due to agentic AI. Well, time flies, and I'm pleased to report that our second dicennial thought experiment on "Steps towards an Ecology for the Internet" will appear at the 2025 edition of Aarhus this August!

This time around, we projected our imaginations forward a decade to imagine an optimistic future for the Internet, when it has exceeded a trillion nodes. After deciding in the pub that this many nodes was too many for us to handle, we turned to our newfound buddies in conservation to get inspiration from nature. We asked Sam Reynolds, Alec Christie, David Coomes and Bill Sutherland first year undergraduate questions about how natural ecosystems operate across all levels of scale: from DNA through to cells through to whole populations. We spent hours discussing the strange correspondences between the seeming chaos in the low-level interactions between cells through to the extraordinary emergent discipline through which biological development typically takes place.

Then, going back to the computer scientists in our group and more widely (like Cyrus Omar who I ran into at Bellairs), it turns out that this fosters some really wild ideas for how the Internet itself could evolve into the future. We could adopti biological process models within the heart of the end-to-end principle that has driven the Internet architecture for decades!

New preprint survey on energy-aware deep learning on embedded hardware / May 2025

Josh Millar has just released the latest survey paper he lead on energy-aware approaches to optimise deep-learning training and inference on embedded devices, such as those benchmarked in "Benchmarking Ultra-Low-Power µNPUs" recently.

We present an overview of such approaches, outlining their methodologies, implications for energy consumption and system-level efficiency, and their limitations in terms of supported network types, hardware platforms, and application scenarios. We hope our review offers a clear synthesis of the evolving energy-aware DL landscape and serves as a foundation for future research in energy-constrained computing.

Any comments, please do let any of us know!

Out-of-the-box LLMs are not ready for conservation decision making / May 2025

Our paper on how the careful design of LLMs is crucial for expert-level evidence retrieval has been published today in PLOS One and is available fully open access!

Our findings suggest that, with careful domain-specific design, LLMs could potentially be powerful tools for enabling expert-level use of evidence syntheses and databases. However, general LLMs used "out-of-the-box" are likely to perform poorly and misinform decision-makers. By establishing that LLMs exhibit comparable performance with human synthesis experts on providing restricted responses to queries of evidence syntheses and databases, future work can build on our approach to quantify LLM performance in providing open-ended responses.

In a nutshell, we tested 10 LLMs with six different retrieval strategies on their ability to answer questions related to conservation, benchmarked against the Conservation Evidence database that has been hand-assembled by experts over the last two decades. In some of the retrieval scenarios, models were only allowed to use their pretrained knowledge, whereas in others they had access to the relevant parts of the hand-curated database.

We found that language models had very varying results when relying only on their pretrained data, and were particularly bad at answering questions about reptile conservation. However, given some extra training with the CE database, their performance improved dramatically. When we put these models head to head with human experts (from the conservation evidence team), with a set of questions and with RAG access to the database, we found that the models were just as good as our experts, but answered the questions much much much faster (near instant).

Essentially, LLMs without extra training are likely to perform poorly and misinform decision-makers. This is crucial when considering how to build AI infrastructure for public policymaking.

New preprint on benchmarking ultra-low power neural accelerators / Mar 2025

Josh Millar just released our latest preprint on how to make sense of the growing number of dedicated, ultra-low-power 'neural network accelerators' that are found in many modern embedded chipsets. My interest in this derives from wanting to decouple from the cloud when it comes to low-latency local environments, and this needs fast tensor operations in hardware. Josh found a huge number of interesting NPUs in modern low-cost chips, ranging from ESP32-based boards over to ARM ones. All of these have quite a variety of tradeoffs, from the operations supported (which affects which models can be run on them) to the amount of memory and CPU power.

Updated preprint on LLMs for evidence-based decision support / Jan 2025

We have just updated our preprint on using LLMs for evidence decision support with more evaluation results and corrections from peer review.

Our findings suggest that, with careful domain-specific design, LLMs could potentially be powerful tools for enabling expert-level use of evidence syntheses and databases. However, general LLMs used "out-of-the-box" are likely to perform poorly and misinform decision-makers. By establishing that LLMs exhibit comparable performance with human synthesis experts on providing restricted responses to queries of evidence syntheses and databases, future work can build on our approach to quantify LLM performance in providing open-ended responses.

LIFE metric published in Royal Society Phil Trans B / Jan 2025

After some years of hard work, our Mapping LIFE on Earth biodiversity metric was published today in a special issue of the Royal Society Philosophical Transactions B! The idea behind LIFE is that although human-driven habitat loss is known to be the greatest cause of the biodiversity crisis, we do not yet have robust spatially explicit metrics that quantify the relative impacts of human actions on species extinctions. And that's what LIFE provides: a way to compare the relative impacts of some landuse anywhere in the world, in a manner that is globally applicable.

Horizon scan on AI and conservation published / Dec 2024

Back in July 2024, a large group of conservation and computer scientists got together in the CCI to prioritise the storm of AI-related projects that have been kicking off around the world. Our key goal was to harness AI to accelerate the positive impact of conservation efforts, while minimising harm caused through either the direct or indirect use of AI technologies.

The first horizon scan resulting from this has just been published in Trends in Ecology and Evolution. If you're looking for a gentle introduction to some of the terms in AI from a non-experts perspective, the first section does a good job of defining a glossary as well.

Towards verifiable, privacy-preserving carbon emissions claims / Dec 2024

Customers of online services may want to take carbon emissions into account when deciding which service to use, but it's currently difficult to do so due to the lack of reliable emissions data that is comparable across online services. There's a lot of muddled data out there, and calculating accurate carbon emissions across a computing pipeline involves a number of stakeholders, none of whom are incentivised to accurately report their emissions for competitive reasons!

In this LOCO paper, Jessica Man lead our exploration of mechanisms to support verifiable and privacy-preserving emissions reporting across a chain of energy suppliers, cloud data centres, virtual machine hosting services providers and cloud services providers. The idea is that all of this can ultimately be exposed to APIs that can be consumed by client devices in order to let consumers make direct choices about their decisions based on relative environmental impacts.

Towards a frugal userspace for Linux / Dec 2024

All the work we've been doing on biodiversity (such as LIFE) comes at a fairly large computation and storage cost due to the amount of data that we churn through. This gets worse when you consider the exploratory nature of science -- we sometimes just need to mess around with the large dataset to test hypotheses which are often shown to be wrong. So then, when the LOCO conference came around, we wrote up our thoughts on what a frugal Linux userspace might look like.

The key insight is that the Linux kernel already exposes a number of namespace mechanisms (that we use in Docker, for example), and so we explore a new OS architecture which defaults to deterministic, reusable computation with the careful recording of side-effects. This in turn allows Linux to guide complex computations towards previously acquired intermediate results, but still allowing for recomputation when required by the user. We're putting this together into a new shell known as "Shark", and this first abstract describes our early results.

Prototyping carbon-aware domain name resolution / Dec 2024

Ryan Gibb and I have been thinking about how the current Internet architecture fails to treat the carbon emissions associated with networked services as a first-class metric. So when the LOCO conference came up, we tried extending the DNS with load balancing techniques to consider the carbon cost of scheduling decisions. A next step was then to build a custom DNS server written in OCaml to actively wake machines running networked services as a side effect of the name resolution.

Extending DNS means that we maintain compatibility with existing Internet infrastructure, unlocking the ability for existing applications to be carbon-aware. This is very much a spiritual follow on to the Signposts project that I worked on back in 2013, and have always wanted to return to!
