125 billion parameters on a 12 GB graphics card: what Strata does differently

Strata brings Qwen3.8-Flash-Next, a language model with 125 billion parameters, to an ordinary gaming PC with 12 GB of graphics memory and 32 to 64 GB of RAM. Version 0.1.39 was released on 4 October 2026 for the project, which has only been public since 24 September and already had around 11,000 stars on GitHub on 5 October. This article explains what Strata is, how it works technically, what you need it for and where its limits are.

Mail from the ISS: SSTV images with a Raspberry Pi and a magnetic-base antenna

From 2 to 6 October 2026, the International Space Station is transmitting twelve images via SSTV on 437.550 MHz as part of ARISS Series 33. I received them in Meerane with a Raspberry Pi, an RTL-SDR stick, a simple magnetic-base antenna and OpenWebRX+, and on the first usable pass two images came through cleanly. The deciding factor was not the antenna, but a small script that tracks the frequency during the pass and saves the images itself.

120,314 emails from 26 years: My mailbox moves into its own archive

In September 2026 I merged Outlook, Thunderbird, Evolution and Cyrus mail from 26 years into a local mail archive running Stalwart and Roundcube. In the end there were 120,314 searchable emails, including more than 11,000 that had long been considered deleted. This post shows why Message-IDs do not detect duplicates, what Thunderbird really does when you delete something and how an archive can stay safe without any cloud.
