Is there a way to specify the % of income that is allocated to cash holdings vs. investments? The modeller seems to assume that I will keep all future income as cash, which seems unrealistic.
The people who build FB's ads platform have their performance judged by metrics like revenue, eCPM, and internal relevance scores.
Building capabilities to add arbitrary human-defined rules into those optimization functions only makes their jobs more difficult and is a drag on hitting team targets. I'm curious why you think they're incentivized to do so.
IMO large social media platforms are actually much more capable of running these experiments than academics. (Disclaimer: I work on ads at one of these companies).
Platforms can accurately determine who engaged with an ad (basic logging on their sites), they have infrastructure to create statistically balanced ad experiments, and can also accurately determine whether a conversion happened (either through a conversion pixel or through data brokers).
Running these tests on behalf of advertising clients, or for internal research is fairly standard. If we couldn't prove statistically that our ads were working, I would have left a long time ago.
The 'skype' name in the network requests is more a remnant of a last minute change from the internal product name (Skype Teams) than a statement of the technologies underpinning the product.
The Teams comms/meeting stack was its own thing - an evolution (or frankenstein's monster mix) of Skype for Business and Skype Consumer technologies. That is one of the reasons why Teams did not have interop capabilities with SfB at launch.
Side note: The Skype for Business communications stack is a descendent of Lync/Office Communicator was completely separate from Skype Consumer (only thing it shared was branding).
This is akin to saying "I've heard enough of these NHTSA reports every week when car accidents happen. The thing is, I don't care. I just want things like this to never happen again."
A 0% error rate is a great aspirational target. But it's also important to acknowledge that a complex system may never be perfect. Insisting otherwise is ignoring reality.
There's plenty of reasons to be skeptical of the article, but this isn't one of them imo. It's pretty easy to find a few locations that fit that description, here's one: https://goo.gl/maps/GpJLjQBiLHvpQGA1A
(Note: the comment mentions a "jersey barrier", while the article describes a more generic "highway barricade")
