You could say I'm on the segfault treadmill, but I'm also literally working at a treadmill desk and I don't want that treadmill to segfault

And even after you stopped triggering segfaults, you're probably only sort of done because who knows what other as-of-yet-untriggered segfaults are still hiding deep within the stacks.

The problem with segfaulting code is that you literally can't tell you're done until you're done. Fix one, bam, here's another that you weren't able to trigger because of the first one!

The extra shitty part is it forces everyone into an arms race: choosing to drive a non-SUV on a road full of SUVs comes out of your safety budget.
This is a classic prisoner's dilemma and it needs a strong external (i.e. regulatory) intervention to for e the system out of that zero sum state.

Senior Technical Support Engineer- AUS Remote - Australia

For the first time: @honeycomb.io is hiring open roles in Australia!!! We have this senior role open as well as a mid-level role. job-boards.greenhouse.io/honeycomb/jo...

Once we fill these, we will have a thriving APAC team of 5 people: Field CTO, account exec, customer architect, and 2 support.

The legacy observability vendors' obsession with "cardinality control" is so backwards.

Why *control* cardinality instead of *embracing* it? High-cardinality data isn't a bugβ€”it's the entire point. Your complex systems generate complex data.

Stop building tools that fight reality.

The End of Lookup - Rethinking Search as Infrastructure β€” Graphium Labs- Traditional keyword search is failing. A new, context-aware, intent-based search is emerging as essential infrastructure for better decision-making.

#SemanticSearch #DataInfrastructure #SearchArchitecture

Our latest post, www.graphiumlabs.com/blog/end-of-..., discusses how current search systems and tools are falling apart as they are required to handle an ever growing mass of data, and an increasing level of nuance and complexity.

100% Recall and 100% Precision in Modern Search β€” Graphium Labs- Precision and recall aren’t just technical jargonβ€”they make up the difference between trust and risk in modern search systems. And they matter more than most people think.

This post breaks down why understanding precision and recall is essential when building search and information retrieval systems for high stakes decision making:

In high-stakes environments, like medical diagnostics, legal research, and threat detection, the trade off between high recall and high precision isn’t just a theoretical optimization problem. The choice has real-world consequences.

24.07.2025 18:44 πŸ‘ 2 πŸ” 1 πŸ’¬ 1 πŸ“Œ 0

Ideally, users want both at 100% – all (good) signal, and zero noise. But the way search works under the hood often forces a trade off: higher recall requires looser filters to bring in more results, and consequentially, more irrelevant results or noise, which bring down precision.

24.07.2025 18:44 πŸ‘ 2 πŸ” 1 πŸ’¬ 1 πŸ“Œ 0

Precision means: β€œOf the results that were returned, how many were relevant (correct)?”

And recall says: β€œOf all the correct results, how many were returned?”

24.07.2025 18:44 πŸ‘ 2 πŸ” 1 πŸ’¬ 1 πŸ“Œ 0

In search and information retrieval systems, precision and recall are more than just evaluation metricsβ€”they reflect how well a system aligns with the user’s needs and expectations of relevance and completeness.

So when nuance is important, semantic search built on vector similarity tends to miss the mark by a really, really wide margin.

I'll start: vector embeddings don't encode semantics, they encode substitutability. It _looks right_ if you squint at it, or if the use case is pretty trivial (e.g. "brown" vs. "chocolate" when describing a sofa).

But opposites also have high substituability (good/bad, dark/light, rich/poor, etc.)

Still frame from the movie The Princess Pride of Inigo Montoya saying "I do not think that word means what you think it means" to Vizzini, overlaid with the text "I do not think these words mean what you think they mean" near Inigo Montoya's head, and the text "Semantic search is just vector embeddings cosine similarity" near Vizzini's head.

It's been bothering me for years how "Semantic" in "Semantic search", the way it's built these days, is semantically wrong.

So on this quite lovely Canada day, let's argue semantics about "Semantic".

Super excited to share this! I've known Saem for many years, and once we started talking about what we're building at Graphium Labs, having him join us as CEO felt inevitable.

Why "geometric" is bad:
Geometric refers to a geometric sequence in math, of the form a, ar, ar^2, ar^3, ..., ar^n.
If r>1 and the scale of something grows by the power, you lose control FAST. Nuclear meltdown fast. 99.9999% of the increase occurs in the last microsecond.
Fine -> BAD happens fast
