I Use Erlang Hot Code Updates
At Underjord, a small Elixir consulting team, we embrace the unique capability of Erlang's hot code updates, a feature that allows code changes without stopping the system—a rarity in most runtimes. While Elixir, built on Erlang, supports this, the standard Elixir release process via mix release doesn't facilitate it directly, requiring a patchwork of resources like "Learn You Some Erlang" and AppSignal guides. Influential voices like Bryan Hunter and Chris Keathley advocate for mastering this skill, as exemplified by WhatsApp's success. We use hot code updates for minor tweaks, especially with Nerves on embedded devices, streamlining development by avoiding full firmware uploads. However, full-scale hot code updates demand meticulous care akin to database migrations, with no shortcuts available. More tooling support would be beneficial.

Typesetting and printing a family memoir (2017)
In the 1980s, my great-uncle, André Klat, penned his memoirs on a typewriter, chronicling our family history from 1760 and his life in Egypt. The copy I received was nearly illegible due to excessive photocopying. Determined to preserve this legacy, I embarked on a journey to typeset and print the memoirs as a family gift. Having previously used LaTeX and Prince, I found them unsatisfactory and decided to create my own typesetting system. This involved scanning 236 pages, converting them via OCR, and meticulously proofreading. I designed a custom markup language and incorporated features like automatic hyphenation and kerning. Inspired by early 20th-century French books, I chose Minion Pro for its classic appeal and crafted a cover to complement my great-uncle's brother's 1969 philosophy book. A fascinating discovery was the fate of their furniture company, Ediar, which I traced to its current owners, thanks to Nael Badr. My passion for typography shone through in the details, such as using half spaces before French punctuation and selecting a font with real small caps. The source code for this project is available on GitHub.
Controversy: The memoirs' unclear fate of the Ediar company raises questions about its history post-1960.

Fat cells have a 'memory' of obesity – why it's hard to keep weight off
In a recent study published in Nature, researchers have discovered that human fat cells retain a 'memory' of obesity, which may explain the difficulty in maintaining weight loss. This memory is linked to changes in the epigenome, affecting gene activity in fat cells. Even after significant weight loss, such as through surgery, these epigenetic changes persist, impairing normal fat cell function. The study, involving both humans and mice, highlights that genes associated with inflammation and fibrosis remain active, while those aiding normal fat function are suppressed. This suggests that long-term care is necessary to prevent weight regain. However, the study does not establish a causal link between these epigenetic changes and physical outcomes, which remains a point of contention. The findings emphasize the importance of preventing obesity initially and may help reduce the stigma associated with it.
Australia increasingly hostile toward secure messaging apps
The Guardian reports on the increasing hostility in Australia towards secure messaging apps, highlighting the case of Session, an encrypted messaging app developed by the Oxen Privacy Tech Foundation (OPTF).
