• 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?

• Anchor bugs in Blink engine browsers

  Sander @ August 3, 2023 at 9:03 am

  I've been looking into an issue for work where Google Chrome loads a URL ending in an anchor and scrolls to the incorrect position on the page. Imagine linking to the third heading on a page and Chrome scrolling to a indeterminable position above that. Firefox is not affected.

  After ruling out all JavaScript and the particular HTML source code, it turns out that disabling the html { scroll-behavior: smooth; } CSS style fixes the issue. My theory so I suspect there is a race condition between determining the length of a page and position of the element while scrolling? This results in bugreports such as "Anchorlink going to the wrong place"

  Regular behaviour is also partially broken

  What's more interesting is that blink based browsers are unable to scroll to the anchor even after the page is already loaded!

  Testcase:

  1. load https://downloads.vandragt.com/test-long.html#test This page has an id attribute test set on the header but is otherwise plain text. Any other page will also work though.
  2. The page loads and the scrollposition is correctly set at the test header.
  3. Scroll up a paragraph or more than a screen, and refresh the page. Notice the scrollposition isn't set.
  4. Optionally refresh many times, or press the Enter key in the address bar to attempt to reload the page. However the scroll-position is now permanently broken until you navigate away from the page.

  This results in bug-reports such as "It only goes to a place when you first enter the URL to the browser, it doesn’t go to the same place when you re-fresh the page". Together this erodes the trust in the application and honestly it's hard to believe this has not been more widely reported.

  There's probably an elaborate JavaScript solution but in my opinion a browser's bugs should be fixed by the browser, because in the future when the browser fixes itself a workaround might result in incorrect behaviour. #technology
