Austrian Audio Hi-X25 are excellent open-back headphones available with or without Bluetooth. They punch above their weight for the price, sounding - to my ear, at least - as good as headphones double the price.
To be honest, I used to have an ISP with dynamic addresses and it wasn't a huge deal. The address only changed every month or two. I used afraid.org's dynamic DNS service to get a dynamic address that followed the changes and created CNAME records for my real domain pointing at that. The actual connection was fucking awful but the dynamic IPs never caused any problems.
As for services: Nextcloud is well worth looking into for file sync and photo backup, especially if you've already got a file server running.
"Bluesky" itself is trademarked and all the rest, but it uses AtProtocol which is a completely open federation protocol. AtProtocol doesn't have the support of ActivityPub because it's much newer and also more complicated (for good reason, but still).
The hardware is good and I like the idea in principle but Fairphone's support and software QA is dreadful and you need to hope you never need the former because of problems with the latter. My FP5 was bricked by an update they pushed out and after six weeks of trying to get a solution from their support (four weeks of which they didn't respond at all) I ended up claiming on insurance and buying a Pixel. According to the forums this problem is far from unique to me.
A firmware update from Fairphone bricked mine last year. Not impressed. Apparently it's happened to a lot of people who went to an alternative OS (Lineage) then back to stock. I just woke up one day to a paperweight on my bedside table and the support was horrendous: it took over six weeks to get any response and after another month of back-and-forth with responses taking a couple of days at a time I ended up just claiming on insurance.
The fundamental difference between religion/spirituality and science/reason, as far as I'm concerned is this: religion demands that you accept something as an indisputable truth and that questioning it is not only discouraged but forbidden and will be met with an arbitrarily horrific punishment (eternal damnation, etc), with what the specific something is dependent on the teacher, their interpretations and their intentions. As a mental framework, I don't think it's healthy for either individuals or societies to unquestioningly accept - or be made to accept - that any ideas are defacto sacred.
For your Steam Deck. And your Linux laptop. And your Windows desktop. And your next handheld, which might be an MSI Claw or Lenovo Legion. And so on...
I will never forgive Apple for fucking over the open web. When the iPhone launched it was web-only. You could 'install' web apps, and any device APIs - accelerated graphics, hardware sensors, location, offline storage, intents, contacts lists, push notifications - were user-selected and presented as standard JavaScript interfaces. One app, literally every platform, and iPhone was there first. It was in a period where every platform was rushing to support web applications with high-performance browser engines and Apple looked like they were going to do for websites-as-applications what they had done for USB ten years earlier: recognise it as the best way forward and push it hard, compatibility be damned.
Then the iPhone started selling well and they got fucking dollar signs in their eyes, realising how much money there was to be made forcing everyone to develop on their platform, in their language, for thier devices. Apps, distribution channels, operating system, services, devices, development, all of it on their terms and on thier platforms. The second they became mainstream they started locking everyone into their vertical ecosystem and wringing as much cash out as they could, exposing their hipocracy and showing that they were as anti-competetive and destructive as Microsoft at their 1990s worst.
In 1980, a large number of experts in business and general tech predicted that by 1990 most written communications would be fully electronic, something akin to email. What they didn't predict was the appearance of the fax machine, which was novel enough to be exciting but simple enough to be understood, and people flocked to it. As a result, electronic communication was stalled for about twenty years. I have no doubt that at some point in the future, Apps will be seen the same way but I think it will take a lot longer to get there.
As it happens, I've just finished setting up a system exactly like this for a completely off-grid setup. I needed a Raspberry Pi running Home Assistant to be completely self-contained to monitor an adjacent, larger system that is only powered up intermittently (close enough that the two systems have a common ground).
Short version: the Raspberry Pi and the Huawei LTE router I'm using for connectivity draw a steady 9W between them (there's a lot of monitoring going on). I went with an old pair of 80W panels in very suboptimal positioning, a simple MPPT charge controller and a 110Ah deep cycle leisure battery which costs about €45, €30 and €120 respectively. The system has been running a few months now and the battery had never, ever dropped below 12.4V. The Pi uses WireGuard to connect to my VPS so Home Assistant can be accessed with a web browser since the network I'm using on-site doesn't do public IP addresses.
Sony WF-C700N. I've had my pair for a long time and I wore them on an Interrailing holiday, which included two days of cross-country hiking in Finnmark. In Northern Norway. In February. Not -40°C, admittedly, but below -20°C. They worked a treat and both have big, clicky physical buttons that are easy to use even through a hat, a thick scarf and gloves.
For clarity, are you imagining imaginary unicorns or just regular non-imaginary unicorns?
