  I like to have pinned browser tabs on any window (mail, calendar etc) that do not disappear. These two together help with that:

• PHP-Activate 0.2.0

  Sander @ October 5, 2023 at 8:59 am

  I've released php-activate 0.2.0, a PHP project version manager for Linux systems using native PHP packages.

  Made for those working with multiple projects using a variety of PHP versions, this script will switch to the correct PHP version for the local shell session. It does not require sudo, so even works in IDEs.

  The latest version adds support for the Fish shell. #projects #phpactivate

  When you want to create an exception to a add_header directive in nginx that is declared in an include, just declare it before it, as successive declarations of the same header are ignored. #til

• On personal goals

  Sander @ September 22, 2023 at 9:12 am

  Today, I've realised my overarching goal as a software engineer: create digital experiences that help improve mental health for the people using them.

  Unwittingly I myself have trended towards community software where capitalism, media manipulation and corporate influence is minimised (open-source, privacy first, self-hosting), and writing software with these values in mind.

  In my experience, capitalism and corporate software distort the incentives of software for the financial benefit of it's backers. Media manipulation uses information overload and content agendas to influence the news cycle and change the common values we live by. This ultimately is more important to them than the wellbeing of the person experiencing the artifact, but not to me.

  How have I been unwittingly trying to create positive user experiences:

  • Having ownership over your content through blogging software that does not demand your attention.
  • Creating a safe space for content consumption of trusted resources.
  • Reducing friction in everyday tasks also benefits mental health and reduces frustration.
  • Having peace of mind working on technologies that avoid complexity,
  • Building foundational projects to help understand how to think about replacement products that contain these values.
  • Helping people make time for oneself.

  Made a Linux shell script called BreakAware that calculates the time since your last break as I couldn't find an alternative to Pandan (macOs).

  BreakAware is a lightweight and user-friendly Fish shell script designed to help you maintain a healthy work-life balance. It tracks the time since your last break, whether it's due to PC sleep, hibernation, logout, or session locking. BreakAware empowers you to be more aware of how you spend your time and encourages you to take regular breaks, enhancing your productivity and well-being.

  If you want an example of why we need a viable open source phone ecosystem, try and share some assorted music files from your non-Apple pc to another person’s iPhone. #technology

  Updated my Notetaker tool rundown, with a new current pick. https://brain.vandragt.com/books/workflows/page/notetaking-tools

• RAM Usage Nerdery

  Sander @ August 25, 2023 at 11:49 am

  I've been wondering how much RAM I used on my 32GB Ubuntu derivative workstation, mainly used for web development using docker containers and light vm experimentation. Yes when I spotcheck with htop I have enough RAM free, but do I actually need 32GB, when I'm in the market for a new device or an upgrade?

  It turns out, yes I do ideally.

  The setup

  On startup I've been running this script to save the memory stats into a csv file:

  #!/usr/bin/env bash
  while true
    do free  | grep Mem | tr --squeeze-repeats ' ' ',' | tee --append ~/memory.csv
    sleep 10
  done

  Today (after 15 days) I pulled the stats into a database and browsed it:

  sqlite-utils insert /tmp/mem.db memory-stats memory.csv --csv
  datasette /tmp/mem.db

  Sorting by the available column shows that the lowest value I get is 11.9GB available to be freed.

  The available column is the sum of the Free column plus the portions of the Buffers and Cache columns (or the Buff/cache column) that can be relinquished immediately. The Available column is an estimate, not an exact figure. https://www.howtogeek.com/456943/how-to-use-the-free-command-on-linux/#the-available-column

  I think it's a reasonable measure. This system does not have zram memory compression enabled, that would help probably.

  It has 4GB swap, I did not measure it's usage.

  Hopefully this review helps for people who want to measure their own usage.

  You can search GitHub wikis by using the search bar and then filtering by wiki. That's almost as nice as keeping your notes in a Lamb instance ;-) #TIL

  We really now need a norobots.txt / terms of use for a persons identity to centrally state how a persons information can be not used by big tech. Something linked to indieauth perhaps?
