• Chris Done ☛ My blog now runs on a Raspberry Pi at home

  I grabbed a Raspberry Pi 5 (highly overpowered for a blog), connected it to my router via gigabit Ethernet, and got it running with a simple SD card for the root file-system. All logs (journald) are moved to tmpfs (‘volatile’ storage mode). The blog itself is sync’d via a webhook from GitHub, and is stored in tmpfs, too. Like this, it should run for a couple years without the SD card wearing out.

• Chloé Vulquin ☛ Tailscale on the Train

  Well, remember that a Tailscale exit node is fundamentally wireguard with some magic sprinkles. It remembers your identity since that is what it’s based on, and automatically switches how it will route your tunnel when it receives a UDP packet from your end. Your device will automatically send such a UDP packet when network conditions change. This can then be “resumed” unlike TCP because it’s not a stream based protocol. In the meanwhile, the requesting server will actually see the exit node’s IP, and so nothing will change for it. The practical consequence is that even if your IP changes, if you’re using a wireguard-based default route VPN (which is what a Tailscale exit node is), you no longer have the above failure condition. Even if things go poorly (and they will, repeatedly), you’ll be able to continue loading a given resource chunk by chunk (albeit with many retries) until you either get there, or a lengthier timeout is hit.

• Lee Yingtong Li ☛ Foreground segmentation with JBIG2 for improved PDF compression: pdf-segmented

  JBIG2 is an efficient image compression format for bi-level (bi-tonal) images, which is supported by the PDF file format and common PDF viewers. To date, tooling for producing documents using JBIG2 (particularly open source tooling) has been limited; I have previously presented file-jbig2pdf, a GIMP plugin for generating PDF files using JBIG2. This suffices for simple black-and-white documents, but does not assist when documents contain both black-and-white text and colour graphics.

  In the DjVu format designed specifically for archival, scanned documents can be separated into a black-and-white foreground layer which is losslessly compressed, and a colour background layer which is lossily compressed. This enables more efficient compression. PDF easily supports a similar structure (JBIG2 black-and-white foreground layer, on top of a colour background), and proprietary PDF software (particularly in scanners) can generate analogously structured PDF documents, but I am unaware of any open source software to do so.¹

• Martin Pitt: InstructLab evaluation with Ansible and Wordle

  During this quarter, all employees are asked to become familiar with using Hey Hi (AI) technologies. In the last months I explored using Hey Hi (AI) for code editing and pull request reviews, but I’ll write about that separately.

  But today is another Red Bait day of learning, so I looked at something more hands-on: Install and run InstructLab on my own laptop again, and experiment with it.

  TL/DR: This just reinforced my experience from the last two years about Hey Hi (AI) being too bad and too expensive for what I would expect it to do.

  • Red Hat ☛ LLM Compressor: Optimize LLMs for low-latency deployments

    The exponential growth in large language model (LLM) sizes has significantly outpaced improvements in hardware memory. As recent releases like Meta's Llama 4 Scout (109B parameters) and Llama 4 Maverick (400B parameters) show, deploying these massive models on limited hardware, even datacenter-class 80GB GPUs, requires substantial memory and compute optimizations.

• Android Authority ☛ Running out of memory in Android 16's Linux Terminal? Try this fix

  One of the most exciting new features in the second quarterly release of Android 15 is the Linux Terminal app. This app allows you to run full-fledged Linux applications on Android by booting an instance of the Debian distribution within a virtual machine. This virtual machine shares resources and hardware, such as processing power and storage, with the host Android device. By default, the Linux Terminal app is limited to 4GB of memory, which might be insufficient for demanding development workloads. Fortunately, there’s a simple workaround for this limitation.
