Having stopped using Fractal this week, and now having a #Matrix @element web tab open at all times in Firefox, appears to be quite problematic for laptop CPU temperatures and power consumption (on Linux, with Wayland).

My global system monitor (and about:performance in Firefox) tells me that the Element web client constantly eats 10-15% of one CPU vCore even when Element's tab is not focused, thus keeps waking the CPU, leading to high temperatures and crappy battery life 🫠

What are the odds?

I check to see what’s next on #tcm tonight. Lost Horizon 1937 in 20 minutes.

I surf the guide and click over to The Cooler 2003. The movie is about 50 minutes in. The scene is the reveal of the new casino and Alec Baldwin launches into a monologue about this exact film….lost horizon and Shanghai-La

It’s the #matrix lol #movie

ElementX is *so* much faster than the current stable versions of Element and its various soft forks (I'm currently using SchildiChat).

As I've said before, I'm guessing it will take another 6-12 months for all the Matrix 2.0 upgrades to be rolled out and fully stabilized in the various app and server software. But if ElementX performance is anything to go by, the new and improved Matrix ecosystem will be well worth an open-minded test.

How does one ban all accounts from an entire home server from joining their #Matrix rooms?

I found this doc that talks about "ban lists" but it seems like we have to run some separate bot to do this? matrix.org/docs/communities/mo

@matrix ... help please ?? 😅

@jopa Matrix on enemmän reaaliaikaiseen viestintään (lue: chat) suunniteltu protokolla ja sisältää esim päästä päähän -salauksen oletuksena.

Vähän eri tarkoitus kuin AP:lla, mutta myös paljon yhteistä. Kumpikin on avoin standardi jossa kuka tahansa on tervetullut tekemään clienttejä, serveritoteutuksia tai mitä vaan integraatiota.

Element ja Fluffychat on clienttejä Matrixille, eli samat tunnukset toimii kummassakin vaikka yhtä aikaa. Clienttejä on pitkä lista ja kuka vaan voi tehdä omansa.

#matrix.fi:hacklab.fi -kanavalla on suomenkielistä keskustelua aiheesta. Tervetuloa jos on jotain kysyttävää.

arXiv.orgFrom short-sighted to far-sighted: A comparative study of recursive machine learning approaches for open quantum systemsAccurately modeling open quantum system dynamics is crucial for advancing quantum technologies, yet traditional methods struggle to balance accuracy and efficiency. Machine learning (ML) provides a promising alternative, particularly through recursive models that predict system evolution based on past history. While these models have shown success in predicting single observables, their effectiveness in more complex tasks, such as forecasting the full reduced density matrix (RDM), remains unclear. We extend history-based recursive ML approaches to complex quantum systems, comparing four physics-informed neural network (PINN) architectures: (i) single-RDM-predicting PINN (SR-PINN), (ii) SR-PINN with simulation parameters (PSR-PINN), (iii) multi-RDMs-predicting PINN (MR-PINN), and (iv) MR-PINN with simulation parameters (PMR-PINN). These models are applied to the spin-boson (SB) model and the Fenna-Matthews-Olson (FMO) complex. Our results show that SR-PINN and PSR-PINN, constrained by a narrow history window, fail to capture complex quantum evolution, leading to unstable long-term predictions, especially in nonlinear and highly correlated dynamics. In contrast, MR-PINN and PMR-PINN improve accuracy by extending the forecast horizon, incorporating long-range correlations, and reducing error propagation. Surprisingly, explicitly including simulation parameters such as temperature and reorganization energy in PSR-PINN and PMR-PINN does not consistently enhance accuracy and can even reduce performance, suggesting that these effects are already encoded in the RDM evolution. These findings highlight the limitations of short-sighted recursive forecasting and demonstrate the superior stability and accuracy of far-sighted approaches for long-term predictions.

Some subtle advertising here from Element/Matrix

I wonder what inspired them?
