What is eratosthenes?

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

What is Umbrel?

umbrelOS now pins any Docker container to the home screen — the app store stopped being the boundary.

umbrelOS 1.7 shipped in late April with home screen Shortcuts pointing at websites, custom ports and Docker containers, a text editor built into Files, advanced networking controls, folder sharing from external drives and seventeen new languages. The three patches since have been split between its own bugs — storage error screens, Tor connectivity — and inherited Linux kernel vulnerabilities, with emergency updates for CopyFail in early May and DirtyFrag a week later.

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

◆ Current state

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

◆ Where it's heading

The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.

◆ Prediction

With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.

2.5

umbrelOS now pins any Docker container to the home screen — the app store stopped being the boundary.

◆ Current state

umbrelOS 1.7 shipped in late April with home screen Shortcuts pointing at websites, custom ports and Docker containers, a text editor built into Files, advanced networking controls, folder sharing from external drives and seventeen new languages. The three patches since have been split between its own bugs — storage error screens, Tor connectivity — and inherited Linux kernel vulnerabilities, with emergency updates for CopyFail in early May and DirtyFrag a week later.

◆ Where it's heading

Umbrel is building a desktop metaphor on top of a personal server: 1.5 added encrypted backups, file history and GPU acceleration, and 1.7 adds shortcuts, a text editor and network shares. At the same time, shipping a full operating system means inheriting the kernel's vulnerability schedule, and two of the four releases in this window exist solely because of it. That is the ongoing cost of the model.

◆ Prediction

Expect the Files and home screen surfaces to keep absorbing desktop functionality, since that is where the last two feature releases have concentrated. Also expect the kernel CVE cadence to keep interrupting it — the two May releases arrived a week apart and neither was planned.
