Linguistic tangent: when did "learnings" oust "lessons" as the standard word for "things I have learned"?
"learnings" is a Briticism, innit ?

Not to this Brit. 'Lessons' all the way, both in corporate speak and in my multi-decade involvement in building training and education systems. We did used to identify 'key learning points' which would summarise the main things a student was expected to take away from a course, but I never saw this abbreviated to 'learnings'.
In my corporate experience, the main thing about lessons was whether they were 'identified' or actually 'learned', e.g. following a corporate post-mortem of some cockup/fiasco/disaster.

At the end what ROS provides for that cost, is a IPC, Logging, configuration and a startup tree (through launch system). Waaaay too expensive. - We have moved to standard sockets IPC, or protocol buffers. - For logging just trivial printing. - For configuration to libconfig - For launch system to simple shell scripts.
The beauty with using protobuf, libconfig or whatever is that they're libraries. If you find a better RPC/messaging library for your needs it's easy to replace one library, if you find a better config management you replace one library, if you want better logging you replace one library. I despise the framework approach, it ossifies bad decisions and then it becomes a monumental task to move away from the framework,…
Absolutely! The system is completely modular, and single pieces can be changed.

In a world of total surveillance, the difference between a police state and free society is who has access to the data and what laws are enforced preventing them abusing it. The benefits of all this spy tech are great - if we manage it right. I mean telephone tapping is an example
A valid ethical question is: will this technology do more good than bad? Or put differently: given the bad implications this technology will likely have, is it worth it? Example: "I have made this technology that makes me (and only me) earn 1 cent per day when managed right. Bad actors can use it to hack into hospitals and ransom them". Wouldn't you agree that this hypothetical technology is probably not worth it? In…
So the cost-benefit analysis approach is quite correct - and my personal take is that “surveillance technology” is another way of saying “external accurate memory” - everything I say or do, everyone I talk to and interact with.
We like having dash-cams because they make other peoples bad driving clear to the judge / insurance agent. Something like that for all aspects of your life seems good and that’s just the personal point. Once we start looking at how to aggregate medical data and provide it to researchers - I mean some doctor has come up with stick on Bluetooth ECG monitors - stick on and record for 48 hours.
The problems arise when the data is used unfairly. Look this guys is (social underdog) - we can use the recorded data to prosecute him. That only gets solved when the judges recorded data shows a clear bias … and we live in a fair open democratic society
If we don’t live in such a society then yea, this technology will Almost always have more cost than benefit - but that’s not the technology.

#25This article struck a personal note with me because around the same time (2008-2012) I was really getting into vision, and even got published as an undergrad for imaging sensor fusion work (...my first, only, and likely last only meaningful contribution to my species); while the wider MV/CV community was making incremental gains every few years (anyone else remember Histogram-of-Oriented-Gradients?), that's what they…
A lot of CV that used to be analytical (and benchmarked for metrics on synthetic data) is being replaced by train model on synthetic data to give answer.

Is it? As an Englishman, my instinctive tendency is to blame any corporate buzzword innovations on the US: but perhaps I'm wrong in this instance.

I don't reach the same conclusion when I look at all the documented privacy abuse that is happening, though.
