Initially I thought this was a “vacation-related” tips request, then I remembered Lemmy is mainly US English not UK English. You can buy a pyrography set, an engraving tool some sandpaper and the things needed for acid etching for less than $10 With a little practice you can make a cheap gift more personal by adding the recipients name or a message personal to you both on wood plastic, metal or glass. I used some vinegar, a q-tip, 9v battery, electrical tape, salt and copper wire to acid etching a hunting knife last year as a gift.
Does everyone just forget that Hewlett Packard are Titanic-grade shitbergs. I wouldn’t trust them to help the UK government find Waldo! If there is ever a company guaranteed to create AI that will take over the world and enslave the human race, step aside Cyberdyne… it’s fucking HP here to cartridge-lock you into a human egg sac to feed our new AI overlords.
My dad still uses my iPhone6, still perfectly usable, admittedly that is a 9 year old phone but I’m not seeing anything making that one obsolete in the near future.
As you say modern phones are not progressing that fast any more, it’s time we made Apple and Google support OS updates for longer. Apple certainly charge app developers enough for the burden to be on them and not the 3rd parties.
Writing this on an iPX which got its last update this week, 6 years old now but I’m just waiting for my banking apps to require iOS17. People will blame development costs for excluding older phones but there is no reason iPhones should not get iOS updates for 10+ years to save App developers the work.
The answer is 1:1, conservation of energy means that 1kWh of energy going into the AC you introduce near as makes no difference 1kWh of heat energy into the world. The wonderful thing AC does is amplify that cooling or heating by moving heat from one place to another meaning modern systems can move 5kW of heat using only 1kW of energy. In this example 6kW is outside but you have removed 5kW from inside so it’s still just 1kW net.
If you want to reduce the impact of using your AC you need firstly insulate the crap out of your house to prevent heat escaping or entering. Then you can delve into the world of Mechanical Ventilation Heat Recovery (MVHR), sealing all the air gaps in your home, at least quad-glazing, and finally passive cooling (sun shades over your windows).
Edit: sorry forgot to say for solar powered AC - which is 100% of my systems. I’m ignoring the grid for the above as the only systems I install are combined with at least 3x kW of solar and batteries so they never use grid power.
