  • As a hiring manager, I don’t give a shit about certs. AWS certs, for example, serve primarily as marketing material and free money. Soft skill certs like agile methodology (of which I have several) are equally bullshit in that everything is a pattern not a prescription yet many people miss that and shoot their teams in the foot. There are some security certs I do value, such as CISSP, because they can be required for certain industries and actually do carry some gravitas. Even those, though, aren’t necessarily valuable for the things I actually need my security folks to do.

    I’d say the market is maybe 30/70 split with folks like me and ATS or idiot hiring managers thinking your ability to memorize the specific GCP settings no one uses will actually make you understand why prod blew up. I refuse to get any; I actively support my team getting them as long as they know what they’re getting into.

    The first and third apply to TV, radio, podcasts, or possibly even reading. The second isn’t a guarantee (not conclusive for everyone) and can be solved with technology.

    The real science here is practicing good sleep hygiene. Your phone is one of many things that can fuck with that; it’s only a small part of it.



  • Adding extrinsic rewards for tasks like this can often introduce dark patterns eg maxing reviews to max rewards. It’s not as simple as “just pay someone to read papers.” As much as I detest academic publishers, it’s also not as simple as just throwing everything into open access (which we should do no matter what) and then having folks do it for the good of the community. There will have to be some experimentation with a balance of intrinsic and extrinsic rewards.

    In the US I directly pay for the funding for papers through tuition and taxes. I shouldn’t have to fucking pay a parasitic publisher on top of that just to access that shit. In math at least I don’t mind paying a little here and there for an MAA or AMS journal though.





  • Are you looking for an editor that can format YAML out-of-the-box or with plugins? In my experience, most editors only support a small number of formats out of the box and extend that functionality with plugins. I have yet to find a solid, production editor without a decent YAML formatter. If you’re using one of the common commercial ones, Red Hat maintains many that work explicitly for Ansible.



  • other given statements

    Perhaps this is our fundamental misunderstanding! I am operating under these statements

    P: I have nothing to hide Q: I should not be concerned about surveillance

    In my opinion, everything after this is OP’s proof, ie we have no given statements ergo you calling out modus ponens is meaningless because, from our foundations, we could theoretically have ~P^Q, P^~Q, P^Q, and P^Q. Our foundation provides no context on how P and Q interact, and, as both of us state, albeit for different reasons, we cannot conclude anything about their interaction.


  • Sure! Let’s go back to foundations. The foundation of modus ponens is, quoting your source,

    If P -> Q and P, then Q

    In order for this to work, we must have both P -> Q and P. Will you please quote OP that shows we have P -> Q, as I have asked from the beginning, instead of making personal attacks? Alternatively, if I’m missing something in my foundations, such as “P -> Q can always be assumed in any basic symbolic context without proof,” educate me. As you have bolded, we can use modus ponens if and only if (necessary and sufficient) we have its requirements. If we don’t, per your source, we cannot use it to prove anything.


  • From your source, we must first have P -> Q. You have not demonstrated that. Sure, if we assume that P -> Q, then P -> Q. That’s a tautology. OP’s goal is to prove P -> Q. I’ve said this multiple times as did OP. Your consistent sharing of a truth table is a necessary condition for P -> Q but it is not sufficient. If P -> Q, then the truth table is valid. That’s modus ponens. You still gotta show (or assume like you have been) that P -> Q.

    To quote OP,

    P -> Q

    I will be providing a proof by counterexample

    In other words, P -> Q is an unproven hypothesis. If P -> Q, then your truth table is correct. If we assume P -> Q, then your truth table is correct. But propositional calculus unfortunately requires we prove things, not just show things that will be true if our original assumption is true.


  • You didn’t read OP, regularly refused back anything up, and came in with ad hominem. When others vote in a way that disagrees with you, you claim a conspiracy. I think the only person here acting in bad faith is you. I have tried to expand OP’s understanding of their proposal and you have only attacked people. You have attempted to insult me multiple times. Granted, I did take a swipe at you begging the question, so you could argue some bad faith was merited, but you saying I’ve never done logic while missing me explaining to you the point you’re suddenly trying to make (“necessary but not sufficient”) continues the poor student metaphor.

    I’m sorry you found “good luck” to be patronizing. Does “have fun” work?



  • How so?

    OP said that, given A and B, they would prove A -> B via negation, meaning the truth table you built does not yet exist and must be proved.

    It is rather…

    OP is not trying to use language, OP is trying to use propositional calculus. Using language unattached to propositional calculus is meaningless in this context.

    This is textbook modus ponens

    No, it’s not. Textbook modus ponens is when you are given A -> B. We are given A and B and are trying to prove A -> B. Never in any of my reading have I ever seen someone say “We want to prove A -> B ergo given A and B, A -> B.” I mean, had I graded symbolic logic papers, I probably would have because it’s a textbook mistake to write a proof that just has the conclusion with none of the work. As the in group, we may assume A -> B in this situation; OP was taking some new tools they’ve picked up and applying them to something OP appears passionate about to prove our assumptions.

    how dare you

    I was responding to OP. Why are you getting mad at me instead of getting mad at OP? OP brought propositional logic to a relativistic conversation. My goal was show why that’s a bad idea. You have proven my point incredibly well.


  • You made the same leap that OP did.

    [I]t is logically accepted that there might be other reasons, even unknown.

    No, it’s not. That’s what I’m calling out. This doesn’t follow from A or B and requires further definition. While you’re using to explain case b, OP tried to use it to explain case c. In both cases, you are assuming some sort of framework that allows you to build these truth tables from real life. That’s where my ask for a consistent formal system comes from.

    In your case b, we have not(I have something to hide) and (I am not concerned about surveillance). Since OP is not saying that the two are necessary and sufficient, we don’t really care. However, in your case c, where we have I have nothing to hide and not(I am not concerned about surveillance), both of you say we are logically allowed to force that to make sense. It’s now an axiom that A and not B cannot be; it has not come from within our proof or our formal system. We waved our hands and said there’s no way for that to happen. Remember, we started with the assumption we could prove A -> B by negation, not that A -> B was guaranteed.

    If you’ll notice my last paragraph in my first post basically says the same thing your last paragraph says.



  • Some may have nothing to hide, but still be concerned about the state of surveillance

    This is where your proof falls apart. It follows from nothing you’ve established and relies on context outside of our proof, which does not work with propositional logic. Another commenter goes into a bit more detail with some pre-defined axioms; with the right axioms you can wave away anything. However you have to agree on your axioms to begin with (this is the foundation of things like non-Euclidean geometry; choose to accept normally unacceptable axioms).

    A rigorous proof using propositional calculus would have to start with the definitions of what things are, what hiding means, what surveillance is, how it relates to hiding, and slowly work your way to showing, based on the definitions and lemmas you’ve built along the way, how this actually works. Understanding how to build arithmetic from the Peano Axioms is a good foundation.

    However, by attempting to represent this conversation in formal logic, we fall prey to Gödel’s Incompleteness Theorems, which means something beyond the axioms in our system has to be based on faith. This arguably leads us back to the beginning, where “nothing to hide” and “state surveillance” fall under personal preference.

    Please note that I think “nothing to hide” is bullshit always and do not support heavy surveillance. I like the discussion you’ve started.

    I want someone who knows about these things to respond to this 2012 metastudy that ties naturally fluoridated groundwater to neurological problems. I have used this the past decade to say “well the science is unclear;” I found it back then (2013 at the latest) when I was trying to disprove a crank and really questioned my shit. There was a(n unrelated?) follow up later that questioned the benefits. Since this is very far from my area of expertise, I’m not championing these; I just want to understand why they’re wrong or at least don’t matter in the discourse.

    (Edit: for the educated, there could be a million ways these are wrong. Authors are idiots, study isn’t reproducible, industry capture, conclusions not backed up by data, whatever. I just don’t have the requisite knowledge to say these are wrong and therefore fluoridated water is both safe and useful)

    Update: great newer studies in responses! You can have a rational convo starting with these two that moves to newer stuff.


  • It’s even more funny because there’s so much stuff that really doesn’t belong in museums if you talk to curators. The average person thinks a Picasso would go for millions and be on display anywhere; there are sketches Picasso did that only have value because Picasso drew them not because they’re good Picassos or moving art. This piece has a good perspective. If we hoarded everything ever we’d get to the point where future generations couldn’t make any new art because there would be no space.

    I will never be able to actually touch one of these gems because no museum would let me. At the end of the day there’s not much difference between me flying across the world and standing in line with a bunch of people taking shitty selfies in front of a ton of protective glass to catch a glimpse of one side of this gem and seeing a virtual scan I can move around. Digitize it, send it back where it came from, and look toward new art.
