Does someone know how to change the port for an SSH based cache?
The `user@host:port` pattern doesn't work on my machine.

An investigation of the two-dimensional non-Hermitian Su-Schrieffer-Heeger Model
This communication presents an examination of a two-dimensional, non-Hermitian Su -Schrieffer-Heeger (SSH) model, which is differentiated from its conventional Hermitian counterpart by incorporating gain and/or loss terms, mathematically represented by imaginary on-site potentials. The time-reversal symmetry is disrupted due to these on-site potentials. Exceptional points in a non-Hermitian system feature eigenvalue coalescence and non-trivial eigenvector degeneracies. Utilization of the rank-n…

@… - is there any known issue with using codeberg if on a work-related laptop is Zscaler installed?
git push via ssh -> if Zscaler is on, it's not working.
(I guess it's related to Zscaler not codeberg, but just asking...)

Exploring Topological and Localization Phenomena in SSH Chains under Generalized AAH Modulation: A Computational Approach
The Su-Schrieffer-Heeger (SSH) model serves as a canonical example of a one-dimensional topological insulator, yet its behavior under more complex, realistic conditions remains a fertile ground for research. This paper presents a comprehensive computational investigation into generalized SSH models, exploring the interplay between topology, quasi-periodic disorder, non-Hermiticity, and time-dependent driving. Using exact diagonalization and specialized numerical solvers, we map the system's pha…

Got a little post about how to use #SSH from #Windows workstations; hopefully will complement folks running #Linux game servers to easily manage their game files with

Howto SSH with graphical app on Windows
The game servers we offer to clients usually run Linux for cost and performance reasons, but one of the common complaints from people is that managing the files on those servers is too difficult. "I can't just drag and drop files to it" or "There's no graphical interface to browse files". This guide will provide a couple tools to hopefully alleviate those issues.

Despite being a person who gets confused by SSH keys every time I have to set them up I actually got things working today. Huzzah!

Crikey, just (finally) nailed the 'family photo gallery in a frame' functionality for my mum (with failing memory, in an assisted living situation) across the world. Can control it from here in Aotearoa (via screen share or ssh) with the extraordinarily handy 'RaspberryPi Connect' functionality. The key technologies are:
- Firefox (in kiosk mode),
- Immich (

Grr wanted to add a vagrant freebsd machine but It kept not adding ssh keys. password config did not work. While the fedora base ismage worked.

Photo-induced directional transport in extended SSH chains
We investigate the current-voltage characteristics of an extended Su-Schrieffer-Heeger (SSH) chain under irradiation by arbitrarily polarized light, demonstrating its potential as a light-controlled rectifier. Irradiation of light induces anisotropy in the system, enabling directional current flow and active control of rectification behavior. Our analysis demonstrates that, under optimized light parameters, the rectification efficiency can exceed 90\%. Moreover, the direction of rectification-w…

I’ve never seen this memory issue on #MacOS before. I had left Safari with Mela’s share sheet/importer app snippet open overnight and came back to a nearly unresponsive computer. I assume one of these has a memory leak. I was able to reboot via the shell using SSH from another device.

Sometimes EDITOR=nano on some weird machine I ssh'd to and I just finish editing the config file and move on without having feelings about it.

Finally restricted access to SSH via source IP Address rather than relying on banning IP Address based on failed attempts, only.

One-dimensional interacting Su-Schrieffer-Heeger model at quarter filling: An exact diagonalization study
This study explores the ground-state phase diagram and topological properties of the spinless 1D Su-Schrieffer-Heeger (SSH) model with nearest-neighbor (NN) interactions at quarter filling. We analyze key physical quantities such as the local electron density distribution, correlation functions for bond-order-wave (BOW) and charge-density-wave (CDW) -- by integrating twisted boundary conditions with the Lanczos technique and employing high-precision numerical diagonalization methods, complement…

Dynamically stable topological edge states in an extended Su-Schrieffer-Heeger ladder with balanced perturbation
The on-site potentials may break the symmetry of a system, resulting in the loss of its original topology protected by the symmetry. In this work, we study the counteracting effect of non-Hermitian terms on real potentials, resulting in dynamically stable topological edge states. We show exactly for a class of systems that the spectrum remains unchanged in the presence of balanced perturbations. As a demonstration, we investigate an extended non-Hermitian Su-Schrieffer-Heeger(SSH) ladder. We fi…
