Excellent work and very interesting to read. DX9s very occasionally pop up for sale for silly small money, and now I would seriously entertain getting one just for the fun of having a crack at installing your custom ROM.
Providing updates to everyone waiting simply wastes time and resources; again, you know roughly how long it's going to take as the estimated times are provided. Hassling the agent on your case is unnecessary.
Regarding leaving and returning Australia - Bridging Visa class Bs are made available if you have good reasons to be leaving and coming back.
I can see this from two sides - my (now ex) wife went through getting temporary then permanent residency in Australia; yes, it was a pain and expensive, but Australia has high standards of living etc, which is why lots of people want to come here. The other side is this - immigration is one of the reasons why there are not enough houses to buy or places to rent, making life difficult for citizens or people who have PR or TR. So if the process of having more immigrants who also require housing is expensive or difficult, I think you'll find a lot of people are not particular sympathetic.
I remember when blue LEDs started appearing in guitar FX pedals just out of novelty,resulting in a pedals becoming harder to use as when the pedal was on the brightness meant visibility of the controls was reduced. On pedals I made I always used fine sandpaper to increase the diffusion of each LED, and the result was significantly better. Early blue LEDs,especially, seemed to have a very narrow projection angle.
They sell LED dimming (and blackout) stickers on Amazon, and those things have been a lifesaver for me. My new USB-C charging block is brighter than the sun and the LED is functionally useless, so it's been masked with the blackout version of the stickers, but my Dyson fan which has a blue power LED (which turns to red when it's on heat mode) and BRIGHT WHITE LED temperature readout in heat mode has gotten the dimming treatment. Nice because you can still see the light, but 80% less bright, so I can sleep at night.
Dedicated stickers are probably the nicest option, but I've just used black electrical tape to completely black out a lot of blue LEDs electronics - especially in the bedroom like you. If you want to see the light, a few pinholes are enough to let some light through.
I've just stuck with a single printed page, placed inside the bag and it's outside pockets, with my flight and multiple sets of contact details. However, I haven't lost a bag over hundreds of flights while doing this, so am unsure of the effectiveness.... guess at least the ritual has been working in terms of heading off a loss proactively!
Might I suggest that swearing to learn to improve your swimming skills may be more beneficial to your long-term survival? Plus a lot more fun once you have more confidence in the water.
They've been working on those things in Tallinn for years, and I've only ever seen them operate in a very limited area, and even then it's not unusual to see them seemingly stuck at the nearby rail crossing. Meanwhile a human on a Bolt scooter ate their and their investor's lunch IMO.
In that case, I'm happy to be 'just' a good developer who has used an ORM to create a product that runs an entire company, and has been doing so reliably for 12 years and counting now. OTOH, I took over a role years ago where the 'great developer' before me left behind masses of crazily complicated and hard to understand SQL queries.
As long as you can deliver reliable and maintainable software in a relatively timely manner, it doesn't matter how it's done, and clients sure don't know or care either.
