The homelab power budget reality check: a Raspberry Pi 4 at 5-8W idle vs a used enterprise desktop at 30-60W idle (100W+ under load). At $0.15/kWh, that 50W difference costs ~$65/year. But the desktop gives you 16GB+ RAM, multiple NVMe slots, PCIe for 10GbE/GPU, and real CPU cores for CI/LLM workloads.
Mitigations: SFF/NUC form factor (15-25W), enable C-states, spin down HDDs, schedule heavy jobs off-peak. The break-even vs a new mini PC (N100/i5-1235U at 10-15W) is 3-5 years if you got the desktop free.
Use the right tool: Pi for always-on lightweight services (DNS, VPN, monitoring), desktop for bursty heavy workloads (builds, training, transcoding). They complement each other.

#Apple’s decade-long investment in #neuralprocessing, #unifiedmemory, and #powerefficientcomputing has positioned its devices for the #AIera. #Macs, particularly #MacMinis and #MacStudios, have become popular platforms for AI developers due to their performance, unified memory, #powerefficiency. Apple’s focus on vertical integration, enabling new capabilities through software, and its strong developer community have further contributed to this success. https://www.thedeepview.com/articles/how-apple-s-decade-long-bet-on-chips-won-ai?eicker.news #tech #media #news

Have you heard the claim "Changing 30 lines of code in the #Linux #kernel could cut energy use at some data centers by up to 30 percent" that made the news two or three weeks ago?
Did you wonder if it is really that simple as it sounds in many stories? Then you want to read the following article from @LWN. It describes things in a more nuanced and technical way, as yes, it is not that simple:

I've compiled all 20-80W power supply efficiency tests from Cybenetics into a Google Doc. Might be useful:
