Android app download source?

Hello,

I recently upgraded the server version to v3 (YAY!!) however my android app version (using Obtainium) does not want to upgrade to 3.0.x it is still at 2.7.x

This is the same if I am checking on Droidify (my second app source). I can see that on github, there are APKs for v3 as well.

What is the recommended way to download the Android app? If it is obtainium, how should I configure it?

If it matters, I am running GrapheneOS on a Pixel device. Thanks.

Does anyone has a pet tortoise?

Hello all,

Hope you all are hydrating well in the heat. Me and my partner have recently gotten ourselves a young Eastern Hermann tortoise and wanted to get in touch with people who also have a tortoise/turtle. This will help us in getting advice, suggestions and potentially a friend for our young Olive.

Thanks!

Lecture 1 of Turbulence course

A few weeks ago, I posted an overview of a turbulence course I'm putting together. The first lecture is now up: https://www.youtube.com/watch?v=myI2dymuUHM

It covers briefly how the flow transitions from a laminar to a turbulent state and highlight the role of Reynolds number which is derived properly from scaling arguments on the momentum equation. Alongside, the limiting cases (Stokes and Euler), what the characteristic scales actually mean for pipe flow and flat plate boundary layers, and a look at the Kelvin-Helmholtz instability is discussed.

It's aimed at senior undergrad, postgrad students and engineers who want a deeper understanding, not just the results. Notes are shared in the comments of the video. Feedback (both positive and constructive) is welcomed and appreciated.

YT course on turbulent flows

Hi everyone! I've been invested in fluid mechanics research for a while now, and I've wanted to put together an introductory course on turbulence for some time. One that connects the physics directly to the equations that are derived from first principles. I've just posted an overview video kicking off that series. It's aimed at senior undergrads, postgrad students, and engineers who use turbulence models in solvers like ANSYS or OpenFOAM and want to understand what's actually going on under the hood.

The course covers two halves: the first on flow physics (Reynolds decomposition, RANS derivation, TKE budget, Kolmogorov theory, wall-bounded and free shear flows), and the second on modelling and computation (k-ε, k-ω SST, LES, solver implementation and data analysis). Lecture notes will be shared alongside each video.

If that sounds like something useful, the overview is here: https://www.youtube.com/watch?v=436HwwfMH4A

Happy to hear any thoughts on the structure or topics, always useful to know what gaps people feel are missing in existing resources.

Hello everyone,

While riding to work this morning, my phone slipped out of pocket and has been switched off ever since (1+ hour at the time of writing). I am based in Oxford, UK, if that is of any help. I am in bit of a panic as I have recently moved to UK and facing this situation for the first time.

Till now, I have contacted my mobile network provider and asked for a replacement sim thereby disabling the current sim. I was running GOS with sandboxed play services. I have also removed the device/logged sessions from my 2FA app (Ente Auth) and my primary bank. If anyone has an understanding, what else can I do to ensure that the device is not misused and I don't face further trouble?

Happy to answer questions.
