Tangentially related lecture: The hard parts of open source.

Collaborative engineering has more problems in collaboration than engineering. Those 'soft' skillsets do not correlate well with technical expertise, especially when filtered through asynchronous (and often pseudonymous) text-based communication. Additionally, some foundational assumptions about the nature of improving technology and society turn out to not work so good.

The patterns of behavior that people fall into because of software are rarely positive for themselves or others. Use and development both invite what Skinner would call superstitions: spurious connections between actions and outcomes. […]This extends to human interactions about software. People can be driven to sociopathy, apathy, obsessive placation, or anything in between, thanks to the sparse, arbitrary, and frankly batshit crazy stimuli they're subjected to.

We're not dutifully working around harmful narcissists out of conscious tolerance or demographic over-representation. They just blend in with all the other assholes we've become.

Here's one of my favourite scenes from 1999’s "The Talented Mr. Ripley": Tom’s first peek into the good life as Dickie and his friends are having an absolute blast in a Naples nightclub¹ and performing Tu Vuo' Fa l'Americano (alternative link).

I seriously wonder how the productions of Patricia Highsmith's novel inevitably ended up being so… glamoruous. There's nothing remarkable about Tom, apart from his insidious, innate drive to claw his way up the top of the bucket of rats. Neither is Highsmith's spiteful and contemptuous writing - yet I find myself quite pulled toward her Novels, be it the full Ripliad, "Strangers on a Train" or "Cry of the Owl", or dramatizations such as the excellent BBC ones or "Carol" (The Price of Salt).

The films, however, are a sight to behold. The Talended Mr. Ripley's cast is riveting. Quite the difference to view them as young as they were back then:

• Jude Law, a charming young philanderer, as opposed to the creepy old philanderer he now seems to be,
• Gwyneth Paltrow still interested in acting (and being great at it!) instead of hawking poison to the most gullible of affluent suckers,
• Matt Damon still possessing enough edge to hide his immense charisma and charm behind the mask of Tom's shifty, untrustworthy, barely-hidden malevolence,
• and Philip Seymour Hoffman, well, being alive.

So, please enjoy this blast from the past with Tu Vuo' Fa l'Americano as performed by Rosario Fiorello and the Guy Barker International Quintet. Or perhaps you'd enjoy the song as performed by the Gypsy Queens?
The meaning behind l'Americano fits with some of the story’s themes in a funny way, with Tom as narrator remarking that Americans immediately go for Italian suits, while in turn Italians have a penchant for English cuts.

The rest of the soundtrack is also swell, with Sinead O'Connor’s Lullaby for Cain eerily setting the mood, and composer Gabriel Yared building great soundscapes as well.

The flow of Benny Goodman's "Sing Sing Sing" visualized by moving letters. Neat.

I inherited a simple Telegram bot from someone. The ease of programming these small things really makes programming fun again.

You don't need any more than plain python and the requests module to run it.

The SonyDevWorld bot

• trawls the Latest updates and Open source archives pages from developer.sony.com
• and posts found items
• to the SMDW_downloads Telegram channel.

While working on the bot, I familiarized myself once again with deploying small isolated services with systemd and it's --user features. Pretty neat.

I also wrote a small ansible role to deploy the bot onto a server.

Building upon my previous explorations, I wanted to let people without an OS-wide dark-mode toggle try it out themselves directly.

For that, we use the styleSheets.cssRules browser API.

Try it! toggle dark/light

function toggleDark() {
  let stylesheets = document.styleSheets;
  for (let sheet of stylesheets) {
    try {
      ruleList = sheet.cssRules;
      if (ruleList == undefined) {
        continue;
      }
    } catch (e) {
      // Catch CORS denials and skip stylesheet
      continue;
    }
    let dark = "(prefers-color-scheme: dark)"
    let light = "(prefers-color-scheme: light)"
    for (let rule of ruleList) {
      /* type 4 == CSSMediaRule */
      if (rule.type !== 4) {
        continue;
      }
      let text = rule.media.mediaText;
      if (text.slice(0, 22) == "(prefers-color-scheme:") {
        rule.media.mediaText == dark ?
          rule.media.mediaText = light :
          rule.media.mediaText = dark
      }
    }
  }
}

Caveat: If testing this on local file:// URIs, CORS will bite you, either on Chrome or FF. On FF, at least you can remedy this by setting privacy.file_unique_origin=false in about:config. See CVE-2019-11730.

For Firefox, you'd be better off installing the website-dark-mode-switcher add-on instead.

I've recently reworked a whole lot of my pages to work with prefers-color-scheme. Not nearly as much work as I'd thought, lots of fun and the results look stunning.

See Dark Mode rework for details.

Calming, late-night highway music. Great for finding your inner peace in case you've lost track of it.

So we sit in empty rooms and dream our lives away
While the spirits come and go without a sound
Yeah just like you and me, they're tryin' to find a way, find a way, find a way home.

Official Video - Lyrics

Posting this mainly so I don't forget myself. In German, because that's the way I learnt it.

Knots

• Ankerstich, Prussig, Doppelter Prussig
• Mastwurf
• Halbmastwurf
• Halfmastwurf mit Sicherungsschlag -> "Halbmastwurf is never alone!"
• Achter
• Sackstich (Hausfrauenknoten)

Climbing

• Use eight-knot for securing to lap belt
• Use Halbmastwurf for belaying when securing a climber, keep end of rope (upwards?)
• Must be clipped in at the top with two counter-facing carabiners when rappelling
• When climbing along a rope course, have your two carabiners always clipped into opposite directions

Rappelling

• Have ready: Two carabiners at the ends of your "tentacles"
• Eighter metal piece for rappelling
• Prussig, at the back
• Using upper body strap, not lower

Misc

• Connect two ropes by weaving an eighter from both sides, it's the most practical that way

Man, does it feel great to run. I hadn't previously run more than five kilometers at a time regularly, but now I don't feel like I've even accomplished the bare minimum if I don't break ten. At some point, you don't even need music in your ears to keep you going, you just enter deeper into the zone.

Yes, this entry is pretty braggadocious. I felt the need to write it down nonetheless.

I'm beginning to warm up to Bluegrass music. Damn shame the Banjo's so heavily associated with red-state hillbillies when in actuality it is a very demanding and soulful instrument. The lyrics are wandering into darker territory, a welcome change from Country banalities.
