Keeping Mastodon storage in check

· Software, www

For my Mastodon instance, I use Cloudflare R2; mainly for two reasons:

  • Storage was growing quickly (~80Gb during its peak); I am hosting my instance on a RPi4 (w/ 8Gb RAM) and the SSD was filling up rapidly,
  • I wanted something speedy to serve (big and cacheable) content (i.e. a CDN).

While I didn't care much about storage any more, I still wanted to make sure it was kept in check, also for two reasons:

Nature in an urban setting

· Misc

I’m very fortunate to have a handful of new trees, some grass and public seating bookend the street I live in. One of my favourite times of the day to be out on my balcony is dusk, because when the sun starts setting and the hustle and bustle of the city subsides, a group of Indian myna birds, attracted by that greenery, playfully chirps and flies between the trees. The tweeting draws out neighbours, too, and creates a beautiful moment of connection through nature in an otherwise man-made environment.

Kids and urban space

· Misc

My local council recently bought a bunch of warehouses and turned them into a public park with a playground. What used to be a barren, semi-industrial area suddenly came alive with people and plants. Everyone visiting the park looked in surprise at the playground wondering the same thing: ‘Where have all of these kids been hiding?’

Today’s urban spaces are designed for cars and commerce, making them particularly hostile towards kids. With most streets being considered unsafe, there has been a huge drop in outdoor play. This study, for example, claims that today just 27% of children play outside their homes, compared to 71% of the baby boomer generation. Or look at this fascinating map showing how an eight year old’s ‘range of exploration’ has changed from ~10 km a few generations ago to a mere ~300 metres today.

Al & Capitalism

· Misc

So, I would like to propose another metaphor for the risks of artificial intelligence. I suggest that we think about A.I. as a management-consulting firm, along the lines of McKinsey & Company. Firms like McKinsey are hired for a wide variety of reasons, and A.I. systems are used for many reasons, too. But the similarities between McKinsey — a consulting firm that works with ninety per cent of the Fortune 100 — and A.I. are also clear. Social-media companies use machine learning to keep users glued to their feeds. In a similar way, Purdue Pharma used McKinsey to figure out how to "turbocharge" sales of OxyContin during the opioid epidemic. Just as A.I. promises to offer managers a cheap replacement for human workers, so McKinsey and similar firms helped normalize the practice of mass layoffs as a way of increasing stock prices and executive compensation, contributing to the destruction of the middle class in America.

Flipper Zero: Waiting for SD card

· Hardware, Software

Just got myself a Flipper Zero because #whynot.

However, the updating process from 0.6x.y to 0.82.3 was not very smooth sailing:

  • First it was stuck in synchronising on the iOS app refusing to initiate the update (had to force quit + reboot Flipper Zero to get it to continue)
  • After that, once I managed to upload the new firmware, it was stuck on Waiting for SD card after the Flipper rebooted.

The SD card I tried was an old 2Gb Samsung SD I had lying around (have 3-4 of these).
