Napisałem sobie widget do KDE, który pokazuje stan baterii w kemperze - narazie status naładowania i kierunek prądu (taak - power jest odwrócone w victronie znaczy, że rozładowuje a "-" ładuje).

Całość implementacji jest ciekawa, bo podłączyłem sobie Raspberrypi zero 2W obok. Zrobiłem tam bridge do MQTT od CerboGX i tunel przez wireguard do mojego VPC. Potem laptop też ma tunel i przez niego czyta sobie z tego RPI. Jeszcze kilka drobiazgów było potrzebne, jak wysyłanie do mqt…

Nyt ollaan taas espoolaisen kuntoliikunnan ytimessä. Ei ole niin väliä, vaikkei saunaan, altaaseen tai maauimalan ulkoalueelle mahtuisi mutta hätä tulee, jos parkkipaikkaa ei löydy!
Maauimalan puolella on sellainen pari metriä syvä, 25 m leveä ja 50 m pitkä vedellä täyttynyt kuoppa ihan käyttämättä (ei autoja) niin siihen saisi helposti 2-kerroksisen parkkitalon.

M2-brane indices on Higgs vacua
As an exact count of protected states, the superconformal index provides a powerful probe into holography and quantum aspects of gravity, reproducing the Bekenstein-Hawking entropy of supersymmetric AdS black holes in the large-$N$ limit. As a step toward understanding quantum black hole microstates, we study the finite-$N$ index of the 3d ADHM quiver gauge theory, a UV description of the 3d $\mathcal N=8$ SCFT dual to M-theory on AdS$_4 \times S^7$. In this note, we analyze both microcanonical…
