micheda··on Ask HN: Who is hiring? (June 2026)
Logenta.ai | Founder/CTO | Germany

We're building an agentic data analytics companion for intralogistics.

Looking for a hands-on founder/CTO who can design and ship an agent-based system end-to-end. You're comfortable building an agent harness, write clean typed Python, and have experience with tools like uv, DuckDB, and PydanticAI. You must be based in Germany.

If this sounds like you, email: michele.dallachiesa+logenta-cto2@sigforge.com with subject "HN Who's Hiring - Logenta CTO". Include your CV and answer one question: "why me?".

micheda··on Show HN: MLtraq – Track and Collaborate on AI Experiments (Open-Source)
Hi! OP here, addressing one more question I received somewhere else:

3) “Can it also track the model's state during training if, e.g., there is an early stop, and then I want to continue the training process?”

With MLtraq, You can dump and load arbitrary objects, including model weights and other state parameters. Let's consider the example https://mltraq.com/howto/02-artifacts-storage/. MLtraq dumps and reloads from the filesystem the binary blobs referenced in the tracked metadata. Similarly, you can store artifacts in third-party services and data stores.

micheda··on Predictive analysis and mitigation of risks in project management [video]
Author here, happy to answer any questions! Accompanying description for the video:

Together with Oxford Global Projects, we have built a family of forecasting models for S-curves using data from a total of 2,700 years of combined construction activity, with an aggregate cash flow of USD 60bn.

The S-curve in project management is a graphical representation that illustrates the cumulative progress of a project over time. It is called an "S-curve" because its characteristic shape resembles the letter "S": It starts slowly, accelerates, and then levels off.

Project delays and budget overruns are often linked with anomalies within the expenditure profile, like a sluggish burn rate or unexpectedly high spending towards anticipated project completion. Timely identification of these anomalies empowers proactive intervention to realign projects on the path to success.

This short video shows how we're modelling expenditure curves to enable many use cases, including spending projections, cost overruns and underruns, outlier analysis, and more.

micheda··on Acceleration of public GitHub repositories at OpenAI | Anthropic | Cohere
Author here, happy to answer any questions! Accompanying description for the video:

Which repositories show the fastest growth? Are there any notable patterns worth highlighting? Let’s find out! The analysis considers 158 public GitHub code repositories at OpenAI, Anthropic and Cohere, created since August 2014, with an aggregate of 12k commits.

The S-curve in project management is a graphical representation that illustrates the cumulative progress of a project over time. It is called an "S-curve" because its characteristic shape resembles the letter "S": It starts slowly, accelerates, and then levels off.

The cumulative number of code commits over time can be used as raw data to model development progress “cost” with S-curves. Similar results can be obtained with the count of distinct authors (harder to control) and the count of modified files.

The animation illustrates the progression of commits over time, with normalisation applied to both axes. Each frame captures a snapshot of the repositories at a specific moment in time. A combination of the fastest and slowest repositories is highlighted with colors and labels. Quiet projects cluster in the top-left corner, and accelerating projects are found in the bottom-right area.

Over time, patterns tend to stabilise. Projects with synchronised acceleration can be attributed to coordinated commits from private repositories. The Python APIs for OpenAI, Anthropic, and Cohere stand out as some of the most active repositories, with OpenAI taking a prominent role in the Node.js / Typescript API development. 5 out of 8 of the most active repositories belong to OpenAI.

S-curves in software development are well-equipped to run simulations, comparative performance analyses, identify project delays and anomalies, and optimise resources in large teams with multiple projects.

micheda··on Homoscedasticity and Heteroscedasticity
In statistics, a sequence (or a vector) of random variables is homoscedastic if all its random variables have the same finite variance. This is also known as homogeneity of variance. The complementary notion is called heteroscedasticity.
micheda··on Ask HN: Best place to start learning about Markov Chains?
The hmm_filter project implements Viterbi-inspired algorithms and transition matrices in Python, might be also a useful learning resource: https://github.com/minodes/hmm_filter
micheda··on Reviewing Zeppelin and Jupyter Notebooks
Hi Ivan, author here. Happy to read that pynb is useful! it can be used in a similar way (I used it also this way until I required support also for Zeppelin), however, it's limited to Jupyter and there's no Markdown support as you already pointed out.
micheda··on Jupytext: Jupyter notebooks as Python scripts
Nice! similar to https://github.com/minodes/pynb , that converts Jupyter Notebooks to Python scripts you can run and back, preserving Markdown cells.
