Hackintoshing as a Sustainable Environmental Practice
https://opengears.medium.com/hackintoshing-as-a-sustainable-environmental-practice-78baf2cdd353
Is #YouTube reducing the average bitrate on 1080p videos for non-Premium users? I always hear about compression artefacts but rarely noticed them, until recently.
You'd think higher compression is good for #EnergyEfficiency. The impact of delaying the expansion of networking hardware is hard to assess. Energy spent on client-side decoding and new client hardware probably dominates.
Results of encoding settings are not obvious:

![Excerpt from "A Survey on Energy Consumption and Environmental Impact of Video Streaming" by Afzal et al.
«With the widespread creation of video coding standards, the complexity of new algorithms has
increased, which has also increased the decoding time and energy consumption [83].
[...]
Resolution. Energy consumption increases with the higher resolution and decoding overhead.
Furthermore, the decoding power, defined as the total power subtracted from the idle power of the
CPU, screen, and network, is not sensitive to the video content and bitrate variations within the
same resolution [217].
Framerate. Yue et al. [217] discovered that increasing the framerate of a video streaming from
30 to 60 frames per second for a given mobile phone resolution doubles the energy decoding. For
other cases, increasing from 7 to 15 and 15 to 30 the increase was more than double.»](https://static.mamot.fr/media_attachments/files/114/001/018/224/947/052/original/4bc2437a8635b390.png "Excerpt from \"A Survey on Energy Consumption and Environmental Impact of Video Streaming\" by Afzal et al.

After re:Invent I spent some time reading about serverless sustainability (both in general and specifically within AWS) and did a write up on the state of sustainability at the end of 2024. Great news: there are some interesting trends and tools to help you tailor your operations to be more carbon aware.

Tout juste avant le premier confinement de Covid, j'ai acheté un Mac mini usagé. Un modèle "late 2014", processeur i5, 16 Go de mémoire, 1 To de stockage. Devenu lent après une malheureuse mise à jour de MacOS, j'ai décidé de le passer à #Ubuntu (Jammy Jellyfish) 22.04, il y a deux ans environ. Amélioration instantanée de performance.
Je viens de terminer la mise à jour à 24.04 Noble Numbat ce matin. Tout roule encore mieux! Une machine qui a 10 ans!
I've been wanting to do this for a year now, and i don't know why it took me so long, but i feel like i slashed my carbon footprint by disabling pipelines for draft MRs

Note that Googlebot very much fails to pay attention to cacheing signals for #RSS files, and Google-Podcast* pays no attention at all to any of these signals. Please fix.
I am hoping to shame Google / Apple / Amazon / Spotify / PodBean into reducing the 99%+ waste from their sloppy behaviour... Eg #LOCO2024
*Why is Google-Podcast still polling my #RSS feed AT ALL, let alone ~140 times per day on a feed that hasn't changed since August?
In #Bielefeld laufen die Vorbereitungen auf die große #LinuxInstallParty (Samstag 15 Uhr in den @acmelabs) auf Hochtouren: 30 USB-Sticks wurden mit jeweils gut 50 Gigabytes GNU/Linux befüllt.
Die Fotos zeigen unsere USB-Stick-Kopiermaschine (vielen Dank fürs Ausleihen, @phillo!) und einen der Sticks im Betrieb. Den 64-GB-Stick könnt ihr zum Materialpreis (5€) mit nach Hause nehmen.
Wozu das Ganze? Damit ihr selbst erleben könnt, dass in euren alten Laptops noch viel Leben steckt, wenn ihr sie mit Linux statt Windows betreibt. In anderen Worten: Steigt von Windows 10 nicht auf Windows 11, sondern auf GNU/Linux um und behaltet eure Hardware, statt neue zu kaufen!
Um uns die Planung zu erleichtern, könnt ihr euer Kommen gern mit einer E-Mail an post@datenpunks.de ankündigen. Erwähnt dabei am besten euren Laptop-Hersteller.
@mathiasx and I were having an interesting back and forth, and his post got me thinking:
For all #softwaredev #programmer #cloudengineer types out there, what energy audit tools are out there right now that people could start leveraging to evaluate their code for being more efficient from a "reduce fossil fuel consumption" point of view?
Static analysis, CI tools, etc. All ideas welcome.
@grafana I feel like something like this is in your wheelhouse. Also, any @cncfambassadors in the environmental sustainment TAG know of some tooling?

I'm now working on fixing another small corner of climate change - inefficiency in #RSS #podcasting!
https://www.earth.org.uk/RSS-efficiency.html
One Android postcast app provider has already kindly tweaked theirs in response to my gentle enquiry, but so far #Apple and #Amazon - both polling at insane rates - have not rushed to fix up their servers similarly to follow basic netiquette! %-P
KDE e.V. is looking for a project lead and event manager for environmental sustainability project.

Had an interesting podcast recording on the ecological impact of computing with Loïc Lannelongue at Jesus College Cambridge yesterday. The college is very beautiful and Loic kindly showed me around after our discussions.
