I have a nice application of this technique: when I saw some good discount of something online that I'm not sure whether I really need, I put it aside. Later when I looked at it again, it is often out of stock, so nothing to think about anymore.

I have quite different observations. IKEA's Zigbee devices are the least stable devices I own and with smaller feature set.

For example, I have more than a dozen Zigbee smart outlet around my home, and the IKEA one is the only one that ever hang and became uncontrollable, yet its also the only one without a physical button to toggle and without power monitoring.

One of IKEA's Zigbee remote controls I have also regularly drops connection and I have to remove its battery to reset it from time to time.

The ones I bought from AliExpress of unknown brands are, unfortunately, much cheaper, have more functionalities, and more reliable.


What brands from AliExpress can you recommend?


Don't have any particular brand recommendation. I have been mostly looking for products marketed as compatible with Tuya Zigbee. It seems they are manufactured under many different brands, and usually at the cheaper end, but they work well in general with ZHA.


Except it is hard to imagine there to be enough demand all the time to sustain this for every hour they work, and even in case there is, they would be happy busy making so many burgers for maybe eight hours in a row each day. And let's not ignore that making food is also not the only work for those working in a restaurant.


Not sure whether they are already doing this, but the fiber could simply connect to a relay rather than the operator themselves, that way the operator can still hide far from the connected system and use wireless outside jamming to control if that still makes sense.


Radio controlled drones carrier drones to which the kamikaze drones are linked by fiber. Move the carrier in low EW area then control the kamikazes in high EW areas using the carrier as a relay.


This would be the way. Essentially the system would be an air-to-ground TOW missile. I wonder how difficult it is to source fiber at the scale needed.

However, a drone can take hits in non-critical areas whereas the fiber is even harder to hit but vulnerable to any caliber or shrapnel sent up. May not be a huge issue, though.


> Electricity generation typically results in lots of waste heat

Typically, but may no longer be true with renewables. I don't think any of solar pv, wind, and hydro generates significant heat in the process of their power generation.


This is true, but I only learnt about it after many years into this career, and to be honest I don't enjoy it very much. I still enjoy working with machines more than people.


Canva and Affinity just released another news [1] which makes the pledge that

> We know this model has been a key part of the Affinity offering and we are committed to continue to offer perpetual licenses in the future. If we do offer a subscription, it will only ever be as an option alongside the perpetual model, for those who prefer it.

[1]: https://www.canva.com/newsroom/news/affinity-canva-pledge/


Guess we'll see how well this ages.


Companies always keep promises like this, so I'm sure we have nothing to worry about.


> Now the question is, will I ever get any updates to Photo/Design/Publisher?

They answered the question in their FAQ:

> Will my Affinity apps still get updates?

> Yes! We have many free updates planned for V2, with a continued focus on improvements and the features you ask for.


> If Affinity had a great business of their own, they wouldn’t need to sell.

They don't need to. They mentioned that in their FAQ:

> We have to say that selling Serif was not on our minds at all, but when Canva contacted us (only a couple of months ago!) there was something about it which just felt right.


Riiight. They had a fantastically enjoyable and profitable business going for themselves...but they decided they'd rather give up all control and sell their baby to a much larger corporate entity, give up the future upside from any growth, and play office politics instead of control their own destiny.

...because it just "felt right."


Not really. They did so because people pay MUCH more for much less functionality in Canva, and so accepting the offer gives them a payday they couldn't hope to accumulate themselves.


> "... Currently there are no plans for changes to our business model"

They mentioned exactly that in the FAQ:

> Canva’s business model is subscription, are there any plans to change how Affinity is sold?

> There are no changes to our current pricing model planned at this time, with all our apps still available as a one-off purchase.
