duality··on Everything everywhere is securities fraud
Do these "life hacks" apply in other developed countries, or is the US special in this way too?
duality··on The student loan crisis is really an underemployment catastrophe
If a company is okay with employees "cross training" is that a problem? They're not forced to train employees, but the good ones will.
duality··on Richard Baldwin on the “inhumanely fast” next phase of globalization
I stopped reading when he said IBM Watson was somehow key in this "globotics" revolution. Even IBM seems to have stopped advertising Watson.
duality··on A gentle introduction to persistent homology
Can anyone working in this field comment on how it's applied? For example, what is computed? Homology groups, just the ranks of these groups, or something else? Given these, what does one learn about the data set under analysis? https://en.wikipedia.org/wiki/Topological_data_analysis#Appl... is pretty scant on detail.
duality··on Many Swiss farmers use honor system to sell their products
Very likely different forms of "lower social cohesion."
duality··on Zanzibar: Consistent, Global Authorization System
What is the right data format to move around? JSON?
duality··on Quantum transitions take time – the news is its experimental demonstration
Not sure exactly what you're linking the Wikipedia article on quantum states, but if you like it as a reference, check out https://en.wikipedia.org/wiki/Quantum_state#Mixed_states. The operation of "projecting out" the E&M field in my previous comment would be realized on the density matrix as a partial trace over the electromagnetic field. You can also take the partial trace of this field of the Hamiltonian operator to see the effective dynamics of the atom when "ignoring" the E&M field. This is a fully quantum description of the state, so I stand by the statement that your claim "An atom can be described by its quantum state only if it's isolated and in that case its energy is constant." is incorrect.
duality··on Quantum transitions take time – the news is its experimental demonstration
"An atom can be described by its quantum state only if it's isolated and in that case its energy is constant."

How do you figure? As a contradiction, take your atom+electromagnetic field system, describe the transition from excited atom to unexcited atom + photon state, and project out the E&M field. Voila, now you have a quantum description of an atom transitioning between different energy states. Its dynamics may look funny, i.e. they may appear nonlocal, they may not conserve energy, etc. but that's different from saying "there is not a quantum description of these dynamics" which is what you're claiming.

duality··on Stadia Founder's Edition
Maybe a different class of games will do best on a streaming platform.
duality··on Stadia Founder's Edition
How did you buy Inbox? Wasn't it free?

Seems like a false equivalence "free skin on top of Gmail" != paid-for service like this one.

duality··on Antitrust Troubles Snowball for Tech Giants as Lawmakers Join In
Going to prison doesn't exempt you from the law from the rest of your life.
duality··on Antitrust Troubles Snowball for Tech Giants as Lawmakers Join In
Is regulation really "one and done"? MS got fined (repeatedly) around 2000 so they're done with regulation?

They at least have shady sales tactics.

duality··on Open-Source `Great Satan’ No More, Microsoft Wins over Skeptics
Makes me think of Paul Graham's essay on submarine articles: http://www.paulgraham.com/submarine.html.
duality··on Google Cloud Is Down
FWIW they might still be.
duality··on Google’s Dominance Is No Longer a Sure Thing
It's possible they're looking elsewhere for a reason. In other words, selection bias.
duality··on US newspapers run more photos of school shooting suspects than victims (2018)
That's a far cry from "just the facts" reporting. Is that sort of editorializing in reporting really a step in the right direction?
duality··on Google’s Shadow Work Force: Temps Who Outnumber Full-Time Employees
In my experience, many fintech/Wall Street firms outsource their recruitment efforts to "head hunting" firms.
duality··on Why We’re Switching to gRPC
"Basically any fundamentally correct buffer encoded as message A will decode successfully as message B for any B."

This is incorrect. I suspect you're overextending proto3's treatment of unknown fields to include discarding incorrectly typed fields too. If A has field 1 types as an int, and B has field 1 typed as a string, an A message with field 1 set will not parse as a B message. However, if the A message has no fields set, or sets a field number unknown to B, that could parse successfully with "leftover" unknown fields.

duality··on Google faces first investigation by its European lead authority over GDPR
The EU copyright directive won't help its image once enacted. They may come to wish it remained more about boring fish quotas.
duality··on Japan Begins Experiment of Opening to Immigration
This will likely prove to be a false equivalence.
duality··on Japan Begins Experiment of Opening to Immigration
Mass migration seems to be for economic benefits. A handful of people may immigrate out of appreciation of their new host culture, but millions or tens of millions doing so? Seems unlikely to me. They'll go to earn more money.
duality··on Japan Begins Experiment of Opening to Immigration
It is weird to hear: 1) stop having so many kids, it's bad for the Earth, and 2) we're not having enough kids, let's substitute with immigrants.
duality··on Amazon S3 Batch Operations
But would a batch delete by any other name smell just as sweet?
duality··on Compile-Time DI vs. Run-Time DI
The creators of Guice mention how configuring the dependency graph in Java was a big advantage it offers over older XML-based frameworks like Spring.
duality··on Google Continues Slump After Ad Revenue Growth Slows
Interesting. So they're reporting on a competitor and are known to try to move markets with their stories. Is there oversight? Since I have no legal training I ask naively, do protections for journalism cover a situation where reporters aim to influence and persuade (like editorials) rather than provide "just the facts?"
duality··on Google Continues Slump After Ad Revenue Growth Slows
I wonder if Bloomberg, which also sells ad spots, is an unbiased source of information here.
duality··on Alphabet Announces First Quarter 2019 Results
Is this "buy the rumor, sell the news" in action?
duality··on Visualising per Capita CO2 Emissions – Criticise the US and Canada, Not China
I've wondered why environmental advocacy groups are not more vocal in support of curtailing immigration into the US. If the American lifestyle is more resource intense, wouldn't that be a natural stance to take?
duality··on Buck: A high-performance build tool
Can anyone who's used both compare Buck to Blaze/Bazel?
duality··on Learn TLA+ (2018)
Regardless, thanks for the informative site.
